(b) The ratio indicates a less than one-to-one coverage because the earnings are inadequate to cover the fixed charges for the period. Pro forma combined earnings for the nine months ended September 30, 1997, and the Company's historical earnings for the years ended December 31, 2021 and 1994, were insufficient to cover its fixed charges. The amounts of the deficiencies were $35.1 million, $150 million and $20.5 million, respectively. (c) For purposes of computing the ratio, adjusted earnings consist of income before income taxes and cumulative effect of accounting change plus fixed charges and preferred stock dividends, net of preferred stock dividends of subsidiary and interest capitalized, and fixed charges and preferred stock dividends consist of interest expense, interest capitalized, the portion of rental expense attributable to interest, preferred stock dividends of subsidiary, and preferred stock dividends. The dividends on the 6 1/4% Cumulative Guaranteed Monthly Income Convertible Preferred Shares of Parker & Parsley Capital LLC, a subsidiary of Parker & Parsley, were recorded as interest expense for financial reporting purposes until those shares were converted into common stock of Parker & Parsley on July 28, 1997.

The Prospectus Supplement will also describe any material United States federal income tax consequences or other special considerations applicable to the series of Debt Securities to which the Prospectus Supplement relates, including those applicable to (a) Bearer Securities, (b) Debt Securities with respect to which payments of principal, premium or interest are determined with reference to an index or formula (including changes in prices of particular securities, currencies or commodities), (c) Debt Securities with respect to which principal, premium or interest is payable in a foreign or composite currency, (d) Debt Securities that are issued at a discount below their stated principal amount, bearing no interest or interest at a rate that at the time of issuance is below market rates ("Original Issue Discount Debt Securities"), and (e) variable rate Debt Securities that are exchangeable for fixed rate Debt Securities. Payments of interest on Registered Securities may be made at the option of the Company by check mailed to the registered holders thereof or, if so provided in the applicable Prospectus Supplement, at the option of a holder by wire transfer to an account designated by the holder. Except as otherwise provided in the applicable Prospectus Supplement, no payment on a Bearer Security will be made by mail to an address in the United States or by wire transfer to an account in the United States. Unless otherwise provided in the applicable Prospectus Supplement, Registered Securities may be transferred or exchanged at the office of the Trustee at which its corporate trust business is principally administered in the United States or at the office of the Trustee or the Trustee's agent in the Borough of Manhattan, the City and State of New York, at which its corporate agency business is conducted, subject to the limitations provided in the Indenture, without the payment of any service charge, other than any tax or governmental charge payable in connection therewith. Bearer Securities will be transferable only by delivery. Provisions with respect to the exchange of Bearer Securities will be described in the Prospectus Supplement relating to the Bearer Securities. All funds paid by the Company to a paying agent for the payment of principal, premium, or interest with respect to any Debt Securities that remain unclaimed at the end of two years after the principal, premium, or interest shall have become due and payable will be repaid to the Company, and the holders of the Debt Securities or any coupons appertaining thereto will thereafter look only to the Company for payment thereof. GLOBAL SECURITIES The Debt Securities of a series may be issued in whole or in part in the form of one or more Global Securities. A Global Security is a Debt Security that represents, and is denominated in an amount equal to, the aggregate principal amount of all outstanding Debt Securities of a series, or any portion thereof, in either case having the same terms, including the same original issue date, date or dates on which principal and interest are due, and interest rate or method of determining interest. A Global Security will be deposited with, or on behalf of, a Depositary, which will be identified in the Prospectus Supplement relating 6 9 to the Debt Securities. Global Securities may be issued in either registered or bearer form and in either temporary or definitive form. Unless and until it is exchanged in whole or in part for the individual Debt Securities represented thereby, a Global Security may not be transferred except as a whole by the Depositary to a nominee of the Depositary, by a nominee of the Depositary to the Depositary or another nominee of the Depositary, or by the Depositary or any nominee of the Depositary to a successor Depositary or any nominee of the successor. The specific terms of the depositary arrangement with respect to a series of Debt Securities will be described in the Prospectus Supplement relating to the Debt Securities. The Company anticipates that the following provisions will generally apply to depositary arrangements. Upon the issuance of a Global Security, the Depositary for the Global Security will credit, on its book-entry registration and transfer system, the respective principal amounts of the individual Debt Securities represented by the Global Security to the accounts of persons that have accounts with the Depositary ("participants"). The accounts shall be designated by the dealers or underwriters with respect to the Debt Securities or, if the Debt Securities are offered and sold directly by the Company or through one or more agents, by the Company or the agents. Ownership of beneficial interests in a Global Security will be limited to participants or persons that hold beneficial interests through participants. Ownership of beneficial interests in the Global Security will be shown on, and the transfer of that ownership will be effected only through, records maintained by the Depositary (with respect to interests of participants) or records maintained by participants (with respect to interests of persons other than participants). The laws of some states require that certain purchasers of securities take physical delivery of the securities in definitive form. Such limitations and laws may impair the ability to transfer beneficial interests in a Global Security. So long as the Depositary for a Global Security, or its nominee, is the registered owner or holder of the Global Security, the Depositary or nominee, as the case may be, will be considered the sole owner or holder of the individual Debt Securities represented by the Global Security for all purposes under the Indenture. Except as provided below, owners of beneficial interests in a Global Security will not be entitled to have any of the individual Debt Securities represented by the Global Security registered in their names, will not receive or be entitled to receive physical delivery of any of the Debt Securities in definitive form, and will not be considered the owners or holders thereof under the Indenture. Subject to the restrictions described under "Description of Debt Securities--Limitations on Issuance of Bearer Securities," payments of principal, premium and interest with respect to individual Debt Securities represented by a Global Security will be made to the Depositary or its nominee, as the case may be, as the registered owner or holder of the Global Security. Neither the Company, the Trustee, any paying agent or registrar for the Debt Securities, or any agent of the Company or the Trustee will have any responsibility or liability for (a) any aspect of the records relating to or payments made by the Depositary, its nominee, or any participants on account of beneficial interests in the Global Security or for maintaining, supervising or reviewing any records relating to the beneficial interests, (b) the payment to the owners of beneficial interests in the Global Security of amounts paid to the Depositary or its nominee, or (c) any other matter relating to the actions and practices of the Depositary, its nominee or its participants. Neither the Company, the Trustee, any paying agent or registrar for the Debt Securities, nor any agent of the Company or the Trustee will be liable for any delay by the Depositary, its nominee or any of its participants in identifying the owners of beneficial interests in the Global Security, and the Company and the Trustee may conclusively rely on, and will be protected in relying on, instructions from the Depositary or its nominee for all purposes. The Company expects that the Depositary for a series of Debt Securities or its nominee, upon receipt of any payment of principal, premium or interest with respect to a definitive Global Security representing any of the Debt Securities, will immediately credit participants' accounts with payments in amounts proportionate to their respective beneficial interests in the principal amount of the Global Security, as shown on the records of the Depositary or its nominee. The Company also expects that payments by participants to owners of beneficial interests in the Global Security held through the participants will be governed by standing instructions and customary practices, as is now the case with securities held for the accounts of customers and registered in street name. The payments will be the responsibility of the participants. Receipt by owners of beneficial interests in a temporary Global Security of payments of principal, premium or interest with respect thereto will be subject to the restrictions described under "Description of Debt Securities--Limitations on Issuance of Bearer Securities." If the Depositary for a series of Debt Securities is at any time unwilling, unable or ineligible to continue as depositary, the Company shall appoint a successor depositary. If a successor depositary is not appointed by the Company within 90 days, the Company will issue individual Debt Securities of the series in exchange for the Global Security representing the series of Debt Securities. In addition, the Company may at any time and in its sole discretion, subject to any limitations described in the Prospectus Supplement relating to the Debt Securities, determine no longer to have Debt Securities of a series represented by a Global Security and, in that event, will issue individual Debt Securities of the series in exchange for the Global Security representing the series of Debt Securities. Furthermore, if the Company so specifies with respect to the Debt Securities of a series, an owner of a beneficial interest in a Global Security representing Debt Securities of the series may, on terms acceptable to the Company, the Trustee, and the Depositary for the Global Security, receive individual Debt Securities of the series in exchange for the beneficial interests, subject to any limitations described in the Prospectus Supplement relating to the Debt Securities. In any such instance, an owner of a beneficial interest in a Global Security will be entitled to physical delivery of 7 10 individual Debt Securities of the series represented by the Global Security equal in principal amount to the beneficial interest and to have the Debt Securities registered in its name (if the Debt Securities are issuable as Registered Securities). Individual Debt Securities of the series so issued will be issued (a) as Registered Securities in denominations, unless otherwise specified by the Company, of $1,000 and integral multiples thereof if the Debt Securities are issuable as Registered Securities, (b) as Bearer Securities in the denomination or denominations specified by the Company if the Debt Securities are issuable as Bearer Securities, or (c) as either Registered Securities or Bearer Securities as described above if the Debt Securities are issuable in either form. See, however, "Description of Debt Securities--Limitations on Issuance of Bearer Securities" for a description of certain restrictions on the issuance of individual Bearer Securities in exchange for beneficial interests in a bearer Global Security. LIMITATIONS ON ISSUANCE OF BEARER SECURITIES The Debt Securities of a series may be issued as Registered Securities (which will be registered as to principal and interest in the register maintained by the registrar for the Debt Securities) or Bearer Securities (which will be transferable only by delivery). If the Debt Securities are issuable as Bearer Securities, certain special limitations and considerations will apply. In compliance with United States federal income tax laws and regulations, the Company and any underwriter, agent or dealer participating in an offering of Bearer Securities will agree that, in connection with the original issuance of the Bearer Securities and during the period ending 40 days after the issue date, they will not offer, sell or deliver any such Bearer Security, directly or indirectly, to a United States Person (as defined below) or to any person within the United States, except to the extent permitted under United States Treasury regulations. Bearer Securities will bear a legend to the following effect: "Any United States person who holds this obligation will be subject to limitations under the United States federal income tax laws, including the limitations provided in Sections 165(j) and 1287(a) of the Internal Revenue Code." The sections referred to in the legend provide that, with certain exceptions, a United States taxpayer who holds Bearer Securities will not be allowed to deduct any loss with respect to, and will not be eligible for capital gain treatment with respect to any gain realized on the sale, exchange, redemption or other disposition of, the Bearer Securities. For this purpose, "United States" includes the United States of America and its possessions, and "United States person" means a citizen or resident of the United States, a corporation, partnership or other entity created or organized in or under the laws of the United States, or an estate or trust the income of which is subject to United States federal income taxation regardless of its source. Pending the availability of a definitive Global Security or individual Bearer Securities, as the case may be, Debt Securities that are issuable as Bearer Securities may initially be represented by a single temporary Global Security, without interest coupons, to be deposited with a common depositary in London for Morgan Guaranty Trust Company of New York, Brussels Office, as operator of the Euroclear System ("Euroclear"), or Centrale de Livraison de Valeurs Mobilieres S.A. ("CEDEL") for credit to the accounts designated by or on behalf of the purchasers thereof. Following the availability of a definitive Global Security in bearer form, without coupons attached, or individual Bearer Securities and subject to any further limitations described in the applicable Prospectus Supplement, the temporary Global Security will be exchangeable for interests in the definitive Global Security or for the individual Bearer Securities, respectively, only upon receipt of a "Certificate of Non-U.S. Beneficial Ownership," which is a certificate to the effect that a beneficial interest in a temporary Global Security is owned by a person that is not a United States Person or is owned by or through a financial institution in compliance with applicable United States Treasury regulations. No Bearer Security will be delivered in or to the United States. If so specified in the applicable Prospectus Supplement, interest on a temporary Global Security will be paid to each of Euroclear and CEDEL with respect to that portion of the temporary Global Security held for its account, but only upon receipt as of the relevant interest payment date of a Certificate of Non-U.S. Beneficial Ownership. SUBORDINATION Debt Securities of a series may be subordinated ("Subordinated Debt Securities") to Senior Indebtedness (as defined below) to the extent set forth in the Prospectus Supplement relating thereto. The Company currently conducts substantially all its operations through subsidiaries, and the holders of Debt Securities (whether or not Subordinated Debt Securities) will be structurally subordinated to the creditors of the Company's subsidiaries. Subordinated Debt Securities of a series and any coupons appertaining thereto will be subordinate in right of payment, to the extent and in the manner set forth in the Indenture and the Prospectus Supplement relating to the Subordinated Debt Securities, to the prior payment of all indebtedness of the Company that is designated as "Senior Indebtedness" with respect to the series. "Senior Indebtedness," with respect to any series of Subordinated Debt Securities, will consist of (a) any and all amounts payable under or with respect to the Company's "Bank Indebtedness" and (b) any other indebtedness of the Company that is designated in a resolution of the Company's Board of Directors or in any supplemental indenture establishing any other series as Senior Indebtedness with respect to the series. "Bank Indebtedness" is defined as (i) the Credit Facility Agreement 8 11 (Primary Facility), dated as of August 7, 1997, between Pioneer Natural Resources USA, Inc. ("Pioneer USA"), as Borrower, and NationsBank of Texas, N.A., as Administrative Agent, CIBC Inc., as Documentation Agent, Morgan Guaranty Trust Company of New York, as Documentation Agent, The Chase Manhattan Bank, as Syndication Agent, and the Co-Agents and Lenders party thereto and (ii) the Credit Facility Agreement (364 Day Facility), dated as of August 7, 1997, between Pioneer USA, as Borrower, and NationsBank of Texas, N.A., as Administrative Agent, CIBC Inc., as Documentation Agent, Morgan Guaranty Trust Company of New York, as Documentation Agent, The Chase Manhattan Bank, as Syndication Agent, and the Co-Agents and Lenders party thereto, each as amended or modified from time to time, and each of which is incorporated by reference as an exhibit to the Registration Statement of which this Prospectus is a part. Upon any payment or distribution of assets of the Company to creditors or upon a total or partial liquidation or dissolution of the Company or in a bankruptcy, receivership or similar proceeding relating to the Company or its property, holders of Senior Indebtedness shall be entitled to receive payment in full in cash of the Senior Indebtedness before holders of Subordinated Debt Securities shall be entitled to receive any payment of principal, premium or interest with respect to the Subordinated Debt Securities, and until the Senior Indebtedness is paid in full, any distribution to which holders of Subordinated Debt Securities would otherwise be entitled shall be made to the holders of Senior Indebtedness (except that the holders may receive shares of stock and any debt securities that are subordinated to Senior Indebtedness to at least the same extent as the Subordinated Debt Securities). The Company may not make any payments of principal, premium or interest with respect to Subordinated Debt Securities, make any deposit for the purpose of defeasance of the Subordinated Debt Securities, or repurchase, redeem or otherwise retire (except, in the case of Subordinated Debt Securities that provide for a mandatory sinking fund, by the delivery of Subordinated Debt Securities by the Company to the Trustee in satisfaction of the Company's sinking fund obligation) any Subordinated Debt Securities if (a) any principal, premium or interest with respect to Senior Indebtedness is not paid within any applicable grace period (including at maturity), or (b) any other default on Senior Indebtedness occurs and the maturity of the Senior Indebtedness is accelerated in accordance with its terms, unless, in either case, the default has been cured or waived and the acceleration has been rescinded, the Senior Indebtedness has been paid in full in cash, or the Company and the Trustee receive written notice approving the payment from the representatives of each issue of "Designated Senior Indebtedness" (which will include the Bank Indebtedness and any other specified issue of Senior Indebtedness of at least $100 million). During the continuance of any default (other than a default described in clause (a) or (b) above) with respect to any Senior Indebtedness pursuant to which the maturity thereof may be accelerated immediately without further notice (except such notice as may be required to effect the acceleration) or the expiration of any applicable grace periods, the Company may not pay the Subordinated Debt Securities for a period (the "Payment Blockage Period") commencing on the receipt by the Company and the Trustee of written notice of the default from the representative of any Designated Senior Indebtedness specifying an election to effect a Payment Blockage Period (a "Blockage Notice"). The Payment Blockage Period may be terminated before its expiration by written notice to the Trustee and the Company from the person who gave the Blockage Notice, by repayment in full in cash of the Senior Indebtedness with respect to which the Blockage Notice was given, or because the default giving rise to the Payment Blockage Period is no longer continuing. Unless the holders of the Senior Indebtedness shall have accelerated the maturity thereof, the Company may resume payments on the Subordinated Debt Securities after the expiration of the Payment Blockage Period. Not more than one Blockage Notice may be given in any period of 360 consecutive days unless the first Blockage Notice within the 360-day period is given by or on behalf of holders of Designated Senior Indebtedness other than the Bank Indebtedness, in which case, the representative of the Bank Indebtedness may give another Blockage Notice within the period. In no event, however, may the total number of days during which any Payment Blockage Period or Periods is in effect exceed 179 days in the aggregate during any period of 360 consecutive days. After all Senior Indebtedness is paid in full and until the Subordinated Debt Securities are paid in full, holders of the Subordinated Debt Securities shall be subrogated to the rights of holders of Senior Indebtedness to receive distributions applicable to Senior Indebtedness. By reason of the subordination, in the event of insolvency, creditors of the Company who are holders of Senior Indebtedness, as well as certain general creditors of the Company, may recover more, ratably, than the holders of the Subordinated Debt Securities. EVENTS OF DEFAULT AND REMEDIES The following events are defined in the Indenture as "Events of Default" with respect to a series of Debt Securities: (a) Default in the payment of any installment of interest on any Debt Securities of that series or any payment with respect to the related coupons, if any, as and when the same shall become due and payable (whether or not, in the case of Subordinated Debt Securities, the payment shall be prohibited by reason of the subordination provisions described above) and continuance of the default for a period of 30 days; (b) Default in the payment of principal or premium with respect to any Debt Securities of that series as and when the same shall become due and payable, whether at maturity, upon redemption, by declaration, upon required 9 12 repurchase or otherwise (whether or not, in the case of Subordinated Debt Securities, the payment shall be prohibited by reason of the subordination provisions described above); (c) Default in the payment of any sinking fund payment with respect to any Debt Securities of that series as and when the same shall become due and payable; (d) Failure on the part of the Company to comply with the provisions of the Indenture relating to consolidations, mergers, and sales of assets;

(f) Indebtedness of the Company or any subsidiary of the Company is not paid within any applicable grace period after final maturity or is accelerated by the holders thereof because of a default, the total amount of the Indebtedness unpaid or accelerated exceeds $20 million, and the default remains uncured or the acceleration is not rescinded for 10 days after the date on which written notice specifying the failure and requiring the Company to remedy the same shall have been given to the Company by the Trustee or to the Company and the Trustee by the holders of at least 25% in aggregate principal amount of the Debt Securities of that series at the time outstanding; (g) The Company or any of its "Significant Subsidiaries" (defined as any subsidiary of the Company that would be a "significant subsidiary" as defined in Rule 405 under the Securities Act as in effect on the date of the Indenture) shall (1) voluntarily commence any proceeding or file any petition seeking relief under the United States Bankruptcy Code or other federal or state bankruptcy, insolvency or similar law, (2) consent to the institution of, or fail to controvert within the time and in the manner prescribed by law, any such proceeding or the filing of any such petition, (3) apply for or consent to the appointment of a receiver, trustee, custodian, sequestrator or similar official for the Company or any Significant Subsidiary or for a substantial part of its property, (4) file an answer admitting the material allegations of a petition filed against it in any such proceeding, (5) make a general assignment for the benefit of creditors, (6) admit in writing its inability or fail generally to pay its debts as they become due, (7) take corporate action for the purpose of effecting any of the foregoing, or (8) take any comparable action under any foreign laws relating to insolvency; (h) The entry of an order or decree by a court having competent jurisdiction for (1) relief with respect to the Company or any of its Significant Subsidiaries or a substantial part of any of their property under the United States Bankruptcy Code or any other federal or state bankruptcy, insolvency or similar law, (2) the appointment of a receiver, trustee, custodian, sequestrator or similar official for the Company or any Significant Subsidiary or for a substantial part of any of their property (except, any decree or order appointing the official of any Significant Subsidiary pursuant to a plan under which the assets and operations of the Significant Subsidiary are transferred to or combined with another Significant Subsidiary or Subsidiaries of the Company or to the Company), or (3) the winding-up or liquidation of the Company or any Significant Subsidiary (except any decree or order approving or ordering the winding-up or liquidation of the affairs of a Significant Subsidiary pursuant to a plan under which the assets and operations of the Significant Subsidiary are transferred to or combined with another Significant Subsidiary or Subsidiaries of the Company or to the Company), and the order or decree shall continue unstayed and in effect for 60 consecutive days, or any similar relief is granted under any foreign laws and the order or decree stays in effect for 60 consecutive days; (i) Any judgment or decree for the payment of money in excess of $20 million is entered against the Company or any subsidiary of the Company by a court of competent jurisdiction, which judgment is not covered by insurance, and is not discharged and either (1) an enforcement proceeding has been commenced by any creditor upon the judgment or decree, or (2) there is a period of 60 days following the entry of the judgment or decree during which the judgment or decree is not discharged or waived or the execution thereof stayed and, in either case, the default continues for 10 days after the date on which written notice specifying the failure and requiring the Company to remedy the same shall have been given to the Company by the Trustee or to the Company and the Trustee by the holders of at least 25% in aggregate principal amount of the Debt Securities of that series at the time outstanding; or (j) Any other Event of Default provided with respect to Debt Securities of that series. An Event of Default with respect to one series of Debt Securities is not necessarily an Event of Default for another series. 10 13 If an Event of Default described in clause (a), (b), (c), (d), (e), (f), (i) or (j) above occurs and is continuing with respect to any series of Debt Securities, unless the principal and interest with respect to all the Debt Securities of the series shall have already become due and payable, either the Trustee or the holders of not less than 25% in aggregate principal amount of the Debt Securities of the series then outstanding may declare the principal amount (or, if Original Issue Discount Debt Securities, the portion of the principal amount as may be specified in the series) of and interest on all the Debt Securities of the series due and payable immediately. If an Event of Default described in clause (g) or (h) above occurs, unless the principal and interest with respect to all the Debt Securities of all series shall have become due and payable, the principal amount (or, if Original Issue Discount Debt Securities, the portion of the principal amount as may be specified in the series) of and interest on all Debt Securities of all series then outstanding shall become and be immediately due and payable without any declaration or other act on the part of the Trustee or any holder of Debt Securities. If an Event of Default occurs and is continuing, the Trustee shall be entitled and empowered to institute any action or proceeding for the collection of the sums so due and unpaid or to enforce the performance of any provision of the Debt Securities of the affected series or the Indenture, to prosecute any such action or proceeding to judgment or final decree, and to enforce any judgment or final decree against the Company or any other obligor on the Debt Securities of the series. In addition, if there shall be pending proceedings for the bankruptcy or reorganization of the Company or any other obligor on the Debt Securities, or if a receiver, trustee, or similar official shall have been appointed for its property, the Trustee shall be entitled and empowered to file and prove a claim for the whole amount of principal, premium and interest (or, in the case of Original Issue Discount Debt Securities, the portion of the principal amount as may be specified in the terms of the series) owing and unpaid with respect to the Debt Securities. No holder of any Debt Security or coupon of any series shall have any right to institute any action or proceeding upon or under or with respect to the Indenture, for the appointment of a receiver or trustee, or for any other remedy, unless (a) the holder previously shall have given to the Trustee written notice of an Event of Default with respect to Debt Securities of that series and of the continuance thereof, (b) the holders of not less than 25% in aggregate principal amount of the outstanding Debt Securities of that series shall have made written request to the Trustee to institute the action or proceeding with respect to the Event of Default and shall have offered to the Trustee such reasonable indemnity as it may require against the costs, expenses, and liabilities to be incurred therein or thereby, and (c) the Trustee, for 60 days after its receipt of such notice, request, and offer of indemnity shall have failed to institute the action or proceeding and no direction inconsistent with the written request shall have been given to the Trustee pursuant to the provisions of the Indenture. Prior to the acceleration of the maturity of the Debt Securities of any series, the holders of a majority in aggregate principal amount of the Debt Securities of that series at the time outstanding may, on behalf of the holders of all Debt Securities and any related coupons of that series, waive any past default or Event of Default and its consequences for that series, except (a) a default in the payment of the principal, premium or interest with respect to the Debt Securities, or (b) a default with respect to a provision of the Indenture that cannot be amended without the consent of each holder affected thereby. In case of any waiver, the default shall cease to exist, any Event of Default arising therefrom shall be deemed to have been cured for all purposes, and the Company, the Trustee and the holders of the Debt Securities of that series shall be restored to their former positions and rights under the Indenture. The Trustee shall, within 90 days after the occurrence of a default known to it with respect to a series of Debt Securities, give to the holders of the Debt Securities of the series notice of all uncured defaults with respect to the series known to it, unless the defaults shall have been cured or waived before the giving of the notice; provided, however, that except in the case of default in the payment of principal, premium, or interest with respect to the Debt Securities of the series or in the making of any sinking fund payment with respect to the Debt Securities of the series, the Trustee shall be protected in withholding notice if it in good faith determines that the withholding of such notice is in the interest of the holders of the Debt Securities. MODIFICATION OF THE INDENTURE The Company and the Trustee may enter into supplemental indentures without the consent of the holders of Debt Securities for one or more of the following purposes: (a) To evidence the succession of another person to the Company pursuant to the provisions of the Indenture to consolidations, mergers and sales of assets and the assumption by the successor of the covenants, agreements, and obligations of the Company in the Indenture and in the Debt Securities; (b) To surrender any right or power conferred upon the Company by the Indenture, to add to the covenants of the Company such further covenants, restrictions, conditions, or provisions for the protection of the holders of all or any series of Debt Securities as the Board of Directors of the Company shall consider to be for the protection of the holders of the Debt Securities, and to make the occurrence, or the occurrence and continuance, of a default in any of the additional covenants, restrictions, conditions or provisions a default or an Event of Default under the Indenture (provided, however, that with respect to any such additional covenant, restriction, condition or provision, the supplemental indenture may provide for a period of grace after default, which may be shorter or longer than that allowed in the case of other defaults, may provide 11 14 for an immediate enforcement upon the default, may limit the remedies available to the Trustee upon the default, or may limit the right of holders of a majority in aggregate principal amount of any or all series of Debt Securities to waive the default); (c) To cure any ambiguity or to correct or supplement any provision contained in the Indenture, in any supplemental indenture, or in any Debt Securities that may be defective or inconsistent with any other provision contained therein, to convey, transfer, assign, mortgage or pledge any property to or with the Trustee, or to make such other provisions in regard to matters or questions arising under the Indenture as shall not adversely affect the interests of any holders of Debt Securities of any series; (d) To modify or amend the Indenture in such a manner as to permit the qualification of the Indenture or any supplemental indenture under the Trust Indenture Act as then in effect; (e) To add to or change any of the provisions of the Indenture to provide that Bearer Securities may be registerable as to principal, to change or eliminate any restrictions on the payment of principal or premium with respect to Registered Securities or of principal, premium or interest with respect to Bearer Securities, or to permit Registered Securities to be exchanged for Bearer Securities, so long as any such action does not adversely affect the interests of the holders of Debt Securities or any coupons of any series in any material respect or permit or facilitate the issuance of Debt Securities of any series in uncertificated form; (f) To comply with the provisions of the Indenture to consolidations, mergers, and sales of assets; (g) In the case of Subordinated Debt Securities, to make any change in the provisions of the Indenture to subordination that would limit or terminate the benefits available to any holder of Senior Indebtedness under such provisions (but only if the holder of Senior Indebtedness consents to the change); (h) To add guarantees with respect to the Debt Securities or to secure the Debt Securities; (i) To make any change that does not adversely affect the rights of any holder; (j) To add to, change or eliminate any of the provisions of the Indenture with respect to one or more series of Debt Securities, so long as any such addition, change or elimination not otherwise permitted under the Indenture shall (1) neither apply to any Debt Security of any series created prior to the execution of the supplemental indenture and entitled to the benefit of the provision nor modify the rights of the holders of any Debt Security with respect to the provision, or (2) become effective only when there is no Debt Security outstanding; (k) To evidence and provide for the acceptance of appointment by a successor or separate Trustee with respect to the Debt Securities of one or more series and to add to or change any of the provisions of the Indenture as shall be necessary to provide for or facilitate the administration of the Indenture by more than one Trustee; and (l) To establish the form or terms of Debt Securities and coupons of any series, as described under "Description of Debt Securities--General." With the consent of the holders of a majority in aggregate principal amount of the outstanding Debt Securities of each series affected thereby, the Company and the Trustee may from time to time and at any time enter into a supplemental indenture for the purpose of adding any provisions to, changing in any manner, or eliminating any of the provisions of the Indenture or of any supplemental indenture or modifying in any manner the rights of the holders of the Debt Securities of the series; provided, however, that without the consent of the holders of each Debt Security so affected, no such supplemental indenture shall (a) reduce the percentage in principal amount of Debt Securities of any series whose holders must consent to an amendment, (b) reduce the rate of or extend the time for payment of interest on any Debt Security or coupon or reduce the amount of any payment to be made with respect to any coupon, (c) reduce the principal of or extend the stated maturity of any Debt Security, (d) reduce the premium payable upon the redemption of any Debt Security or change the time at which any Debt Security may or shall be redeemed, (e) make any Debt Security payable in a currency other than that stated in the Debt Security, (f) in the case of any Subordinated Debt Security or coupons appertaining thereto, make any change in the provisions of the Indenture to subordination that adversely affects the rights of any holder under the provisions, (g) release any security that may have been granted with respect to the Debt Securities, (h) make any change in the provisions of the Indenture to waivers of defaults or amendments that require unanimous consent, (i) change any obligation of the Company provided for in the Indenture to pay additional interest with respect to Bearer Securities, or (j) limit the obligation of the Company to maintain a paying agency outside the United States for payment on Bearer Securities or limit the obligation of the Company to redeem certain Bearer Securities. 12 15 CONSOLIDATION, MERGER, AND SALE OF ASSETS The Company may not consolidate with or merge with or into any person, or convey, transfer or lease all or substantially all its assets, unless the following conditions have been satisfied: (a) Either (1) the Company shall be the continuing person in the case of a merger, or (2) the resulting, surviving or transferee person, if other than the Company (the "Successor Company"), shall be a corporation organized and existing under the laws of the United States, any State, or the District of Columbia and shall expressly assume all the obligations of the Company under the Debt Securities and coupons and the Indenture; (b) Immediately after giving effect to the transaction (and treating any indebtedness that becomes an obligation of the Successor Company or any subsidiary of the Company as a result of the transaction as having been incurred by the Successor Company or the subsidiary at the time of the transaction), no Default or Event of Default would occur or be continuing; (c) The Successor Company waives any right to redeem any Bearer Security under circumstances in which the Successor Company would be entitled to redeem the Bearer Security but the Company would not have been so entitled to redeem if the consolidation, merger, conveyance, transfer or lease had not occurred; and (d) The Company shall have delivered to the Trustee an officers' certificate and an opinion of counsel, each stating that the consolidation, merger or transfer complies with the Indenture. SATISFACTION AND DISCHARGE OF THE INDENTURE; DEFEASANCE The Indenture shall generally cease to be of any further effect with respect to a series of Debt Securities if (a) the Company has delivered to the Trustee for cancellation all Debt Securities of the series (with certain limited exceptions), or (b) all Debt Securities and coupons of the series not theretofore delivered to the Trustee for cancellation shall have become due and payable, or are by their terms to become due and payable within one year or are to be called for redemption within one year, and the Company shall have deposited with the Trustee as trust funds the entire amount sufficient to pay at maturity or upon redemption all the Debt Securities and coupons (and if, in either case, the Company shall also pay or cause to be paid all other sums payable under the Indenture by the Company). In addition, the Company shall have a "legal defeasance option" (pursuant to which it may terminate, with respect to the Debt Securities of a particular series, all its obligations under the Debt Securities and the Indenture with respect to the Debt Securities) and a "covenant defeasance option" (pursuant to which it may terminate, with respect to the Debt Securities of a particular series, its obligations with respect to the Debt Securities under certain specified covenants contained in the Indenture). If the Company exercises its legal defeasance option with respect to a series of Debt Securities, payment of the Debt Securities may not be accelerated because of an Event of Default. If the Company exercises its covenant defeasance option with respect to a series of Debt Securities, payment of the Debt Securities may not be accelerated because of an Event of Default related to the specified covenants. The Company may exercise its legal defeasance option or its covenant defeasance option with respect to the Debt Securities of a series only if (a) the Company irrevocably deposits in trust with the Trustee cash or U.S Government Obligations (as defined in the Indenture) for the payment of principal, premium, and interest with respect to the Debt Securities to maturity or redemption, as the case may be, (b) the Company delivers to the Trustee a certificate from a nationally recognized firm of independent accountants expressing their opinion that the payments of principal and interest when due and without reinvestment on the deposited U.S. Government Obligations plus any deposited money without investment will provide cash at such times and in such amounts as will be sufficient to pay the principal, premium and interest when due with respect to all the Debt Securities of the series to maturity or redemption, as the case may be, (c) 123 days pass after the deposit is made and during the 123-day period no default described in clause (g) or (h) under "Description of Debt Securities--Events of Default and Remedies" with respect to the Company occurs that is continuing at the end of the period, (d) no Default has occurred and is continuing on the date of the deposit and after giving effect thereto, (e) the deposit does not constitute a default under any other agreement binding on the Company and, in the case of Subordinated Debt Securities, is not prohibited by the provisions of the Indenture to subordination, (f) the Company delivers to the Trustee an opinion of counsel to the effect that the trust resulting from the deposit does not constitute, or is qualified as, a regulated investment company under the Investment Company Act of 1940, (g) the Company shall have delivered to the Trustee an opinion of counsel addressing certain federal income tax matters to the defeasance, and (h) the Company delivers to the Trustee an officers' certificate and an opinion of counsel, each stating that all conditions precedent to the defeasance and discharge of the Debt Securities of the series as contemplated by the Indenture have been complied with. 13 16 The Trustee shall hold in trust cash or U.S. Government Obligations deposited with it as described above and shall apply the deposited cash and the proceeds from deposited U.S. Government Obligations to the payment of principal, premium, and interest with respect to the Debt Securities and coupons of the defeased series. In the case of Subordinated Debt Securities and coupons related thereto, the money and U.S. Government Obligations so held in trust will not be subject to the subordination provisions of the Indenture. THE TRUSTEE The Company may appoint a separate Trustee for any series of Debt Securities. As used herein in the description of a series of Debt Securities, the term "Trustee" refers to the Trustee appointed with respect to the series of Debt Securities. The Company may maintain banking and other commercial relationships with the Trustee and its affiliates in the ordinary course of business, and the Trustee may own Debt Securities. DESCRIPTION OF CAPITAL STOCK The authorized capital stock of the Company consists of 500,000,000 shares of common stock, par value $.01 per share ("Common Stock"), and 100,000,000 shares of preferred stock, par value $.01 per share ("Preferred Stock"), of which one share has been designated as Special Preferred Voting Stock. COMMON STOCK All shares of Common Stock issued under the Registration Statement of which this Prospectus is a part will be fully paid and nonassessable. The holders of Common Stock are entitled to one vote for each share held on all matters submitted to a vote of common stockholders. The Common Stock does not have cumulative voting rights. Shares of Common Stock have no preemptive rights, conversion rights, redemption rights or sinking fund provisions. The Common Stock is not subject to redemption by the Company. Subject to the rights of the holders of any class of capital stock of the Company having any preference or priority over the Common Stock, the holders of Common Stock are entitled to dividends in such amounts as may be declared by the Board of Directors from time to time out of funds legally available for such payments and, in the event of liquidation, to share ratably in any assets of the Company remaining after payment in full of all creditors and provision for any liquidation preferences on any outstanding preferred stock ranking prior to the Common Stock. PREFERRED STOCK The Board of Directors, without further stockholder action, is authorized to issue up to 100,000,000 shares of Preferred Stock in one or more series and to fix and determine as to any series all the relative rights and preferences of shares in the series, including voting rights, dividend rights, liquidation preferences, terms of redemption and conversion rights. Special Preferred Voting Stock In connection with the Company's acquisition of Chauvco Resources Ltd., an Alberta, Canada corporation (the "Chauvco Transaction"), the Board of Directors has designated one share of the 100,000,000 authorized shares of Preferred Stock as Special Preferred Voting Stock (the "Voting Share"). The Montreal Trust Company of Canada, or any successor thereto (for purposes of this discussion, the "Share Trustee"), shall hold the Voting Share as trustee for and on behalf of, and for the use and benefit of, the holders of exchangeable shares (the "Exchangeable Shares") of Pioneer Natural Resources (Canada) Ltd., an indirectly-owned subsidiary of the Company ("Pioneer Canada"), and in accordance with the Voting and Exchange Trust Agreement described in "Description of Capital Stock--Pioneer Canada Exchangeable Shares." The Certificate of Designations for the Voting Share includes the following principal terms: Dividends. No dividend shall be paid to the Share Trustee as the holder of the Voting Share. Voting Rights. The Share Trustee, as the holder of record of the Voting Share, shall be entitled to all of the voting rights attached to the Voting Share, including the right to consent to or vote in person or by proxy the Voting Share, on any matter, question or proposition whatsoever that may properly come before the stockholders of the Company at a meeting thereof or with respect to any written consent sought by the Company from its stockholders. For each Exchangeable Share owned of record on the relevant record date, the holder thereof shall be entitled to instruct the Share Trustee to cast and exercise, in the manner instructed, a number of votes (including for purposes of a quorum) equal to the number of votes to which a holder of one share of Common Stock is entitled with respect to any matter, proposition or question on which the holders of Common Stock are entitled to vote. 14 17 Except as otherwise described herein or required by law, the holder of the Voting Share will vote together with the Common Stock as a single class and not as a separate class or series apart therefrom, including any vote to approve or adopt: (i) any plan of merger, consolidation or share exchange for which Delaware law requires a stockholder vote; (ii) any disposition of assets for which Delaware law requires a stockholder vote; and (iii) any dissolution of the Company for which Delaware law requires a stockholder vote. The holders of Exchangeable Shares have the right to submit stockholder proposals to the Trustee and the Trustee has agreed pursuant to the Voting and Exchange Trust Agreement to submit any such proposals to the Company. Such stockholder proposals may be considered at any meeting of the Company at which the holders of Common Stock of the Company are entitled to submit stockholder proposals. The Company has agreed pursuant to the Voting and Exchange Trust Agreement to accept all stockholder proposals submitted by the Trustee provided that not more than one proposal is submitted by the Trustee on behalf of any one holder of Exchangeable Shares. So long as any Exchangeable Shares are outstanding, the number of shares comprising the Special Preferred Voting Stock will not be increased or decreased, and no other term of the Special Preferred Voting Stock may be amended, except upon the approval of the holder of the Voting Share. Conversion. The Voting Share is not convertible into any other class or series of the capital stock of the Company or into cash, property or other rights. Redemption. The Voting Share may not be redeemed, except when no Exchangeable Shares are outstanding, in which case the Voting Share will be automatically redeemed. The redemption price due and payable upon the automatic redemption will be $1.00. The Voting Share will be deemed retired and will be canceled upon any purchase or other acquisition thereof by the Company. After cancellation, the Voting Share may not be reissued or otherwise disposed of by the Company. Liquidation. The Voting Share will rank prior to each share of Common Stock with respect to the distribution of assets upon a liquidation, dissolution or winding-up of the Company. In the event of any such liquidation, dissolution or winding-up, the holder of the Voting Share will be entitled to receive a liquidation preference of $1.00 before any distribution to the holders of Common Stock, but only after the liquidation preference of any other shares of preferred stock of the Company has been paid in full. Certain Covenants of the Company. For so long as the Voting Share is outstanding, the Company will (i) fully comply with all terms of the Exchangeable Shares and with all associated contractual obligations of the Company, and (ii) not amend, alter or repeal the terms and conditions of the Special Preferred Voting Stock, except with the approval of the holder of the Voting Share. CERTAIN PROVISIONS OF THE CERTIFICATE OF INCORPORATION AND BYLAWS The Company's Board of Directors is divided into three classes. The directors of each class are elected for three-year terms, with the terms of the three classes staggered so that directors from a single class are elected at each annual meeting of stockholders. Stockholders may remove a director only for cause. In general, the Board of Directors, not the stockholders, has the right to appoint persons to fill vacancies on the Board of Directors. The Amended and Restated Certificate of Incorporation of the Company (the "Restated Certificate") contains a "fair price" provision that requires the affirmative vote of the holders of least 80% of the Company's voting stock and the affirmative vote of at least 66 2/3% of the Company's voting stock not owned, directly or indirectly, by a Related Person (as defined below) to approve any merger, consolidation, sale or lease of all or substantially all of the Company's assets, or certain other transactions involving a Related Person. For purposes of this fair price provision, a "Related Person" is any person beneficially owning 10% or more of the voting power of the outstanding capital stock of the Company who is a party to the transaction at issue. The voting requirement is not applicable to certain transactions, including those that are approved by the Continuing Directors (as defined in the Restated Certificate) or that meet certain "fair price" criteria contained in the Restated Certificate. The Restated Certificate further provides that stockholders may act only at annual or special meetings of stockholders and not by written consent, that special meetings of stockholders may be called only by the Board of Directors, and that only business proposed by the Board of Directors may be considered at special meetings of stockholders. The Restated Certificate also provides that the only business (including election of directors) that may be considered at an annual meeting of stockholders, in addition to business proposed (or persons nominated to be directors) by the Company's directors, is business proposed (or persons nominated to be directors) by stockholders who comply with the notice and disclosure requirements set forth in the Restated Certificate. In general, the Restated Certificate requires that a stockholder give the Company notice of proposed business or nominations no later than 60 days before the annual meeting of stockholders (meaning the date on which the meeting is first scheduled and not postponements or adjournments thereof) or (if later) ten days after the first public notice of the annual meeting is sent to common stockholders. In general, the notice must also contain information about the stockholder proposing the business or nomination, his interest in the business, and (with respect to nominations for 15 18 director) information about the nominee of the nature ordinarily required to be disclosed in public proxy solicitations. The stockholder also must submit a notarized letter from each of his nominees stating the nominee's acceptance of the nomination and indicating the nominee's intention to serve as director if elected. The Restated Certificate also restricts the ability of stockholders to interfere with the powers of the Board of Directors in certain specified ways, including the constitution and composition of committees and the election and removal of officers. The Restated Certificate provides that approval by the holders of at least 66 2/3% of the outstanding voting stock of the Company is required to amend the provisions of the Restated Certificate discussed above and certain other provisions, except that (a) approval by the holders of at least 80% of the outstanding voting stock of the Company together with approval by the holders of at least 66 2/3% of the outstanding voting stock not owned, directly or indirectly, by the Related Person, is required to amend the fair price provisions, and (b) approval of the holders of at least 80% of the outstanding voting stock of the Company is required to amend the provisions prohibiting stockholders from acting by written consent. DELAWARE ANTI-TAKEOVER STATUTE The Company is a Delaware corporation and is subject to Section 203 of the Delaware General Corporation Law. In general, Section 203 prevents an "interested stockholder" (defined generally as a person owning 15% or more of the Company's outstanding voting stock) from engaging in a "business combination" (as defined in Section 203) with the Company for three years following the date that person becomes an interested stockholder unless (a) before that person became an interested stockholder, the Board of Directors approved the transaction in which the interested stockholder became an interested stockholder or approved the business combination, (b) upon completion of the transaction that resulted in the interested stockholder's becoming an interested stockholder, the interested stockholder owns at least 85% of the Company's voting stock outstanding at the time the transaction commenced (excluding stock held by directors who are also officers of the Company and by employee stock plans that do not provide employees with the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer), or (c) following the transaction in which that person became an interested stockholder, the business combination is approved by the Board of Directors and authorized at a meeting of stockholders by the affirmative vote of the holders of at least two-thirds of the outstanding voting stock of the Company not owned by the interested stockholder. Under Section 203, these restrictions also do not apply to certain business combinations proposed by an interested stockholder following the announcement or notification of one or certain extraordinary transactions involving the Company and a person who was not an interested stockholder during the previous three years or who became an interested stockholder with the approval of a majority of the Company's directors, if that extraordinary transaction is approved or not opposed by a majority of the directors before any person became an interested stockholder in the previous three years or who were recommended for election or elected to succeed such directors by a majority of such directors then in office. PIONEER CANADA EXCHANGEABLE SHARES In connection with the Chauvco Transaction, the Company issued the Voting Share and entered into the Support Agreement and the Voting and Trust Agreement, and assumed certain obligations with respect to the Exchangeable Shares issued by Pioneer Canada. The Exchangeable Shares have the rights and preferences summarized below. Voting Rights. The holders of Exchangeable Shares have voting rights or matters submitted to the holders of the Company's Common Stock as previously described in "Description of Capital Stock--Preferred Stock--Special Preferred Voting Stock." Dividends. Holders of Exchangeable Shares will be entitled to receive dividends equal to dividends paid from time to time by the Company on shares of the Common Stock. The declaration date, record date and payment date for dividends on the Exchangeable Shares will be the same as that for the corresponding dividends on the Common Stock. In the event of the liquidation, dissolution or winding-up of Pioneer Canada, a holder of Exchangeable Shares will be entitled to receive for each Exchangeable Share one share of Common Stock, together with a cash amount equal to the full amount of all unpaid dividends on the Exchangeable Shares. See "Description of Capital Stock--Pioneer Canada Exchangeable Shares--Voting and Exchange Trust Agreement." The rights, privileges, restrictions and conditions attaching to the Exchangeable Shares may be changed only with the approval of the holders thereof. 16 19 Redemption of Exchangeable Shares by Holders. Each Exchangeable Share is redeemable at the option of the holder for one share of Common Stock plus the amount equal of unpaid dividends thereon. The redemption price must be delivered on the date specified by the holder (not less than three nor more than ten business days after the redemption request) and is payable by Pioneer Canada, or, if it is unable to do so, by the Company. Redemption of Exchangeable Shares. Upon at least 120-days prior written notice by Pioneer Canada to the holders of Exchangeable Shares and subject to the Company's redemption call right (as described below), on the Automatic Redemption Date (as defined below) Pioneer Canada will redeem all but not less than all of the then outstanding Exchangeable Shares for one share of Common Stock for each Exchangeable Share plus an additional amount equivalent to the full amount of all unpaid dividends thereon. "Automatic Redemption Date" means December 18, 2003, unless (a) such date shall be extended at any time or from time to time to a specified later date by the Board of Directors of Pioneer Canada but not later than December 31, 2005, or (b) such date shall be accelerated at any time to a specified earlier date (but no earlier than the third anniversary of the first issuance of Exchangeable Shares) by the Board of Directors of Pioneer Canada if at such time there are issued and outstanding less than 5% of the number of Exchangeable Shares initially issued and outstanding in the Chauvco Transaction. Support Agreement Under the Support Agreement, the Company agreed that: (i) it will not declare or pay dividends on the Common Stock unless Pioneer Canada is able to and simultaneously pays an equivalent dividend on the Exchangeable Shares; (ii) it will advise Pioneer Canada in advance of the declaration of any dividend on the Common Stock and ensure that the declaration date, record date and payment date for dividends on the Exchangeable Shares are the same as that for the Common Stock; (iii) it will take all actions and do all things necessary to ensure that Pioneer Canada is able to provide to the holders of the Exchangeable Shares the equivalent number of shares of Common Stock in the event of a liquidation, dissolution, or winding-up of Pioneer Canada, a redemption request by a holder of Exchangeable Shares, or a redemption of Exchangeable Shares of Pioneer Canada; and (iv) it will not vote or otherwise take any action or omit to take any action causing the liquidation, dissolution or winding-up of Pioneer Canada. The Support Agreement also provides that, without the prior approval of Pioneer Canada and the holders of the Exchangeable Shares, the Company will not distribute additional shares of Common Stock or rights to subscribe therefor or other property or assets to all or substantially all holders of shares of Common Stock, nor change the Common Stock nor effect any tender offer, share exchange offer, issuer bid, take-over bid or similar transaction affecting the Common Stock, unless the same or an equivalent distribution on or change to the Exchangeable Shares (or in the rights of the holders thereof) is made simultaneously. The Company has agreed that so long as there remain outstanding any Exchangeable Shares not owned by the Company or any entity controlled by the Company, the Company will remain the beneficial owner, directly or indirectly, of all outstanding shares of Pioneer Canada other than the Exchangeable Shares. With certain limited exceptions, the Support Agreement may not be amended without the approval of the holders of the Exchangeable Shares. Under the Support Agreement, the Company has agreed not to exercise any voting rights attached to the Exchangeable Shares owned by it or any entity controlled by it on any matter considered at meetings of holders of Exchangeable Shares (including any approval sought from such holders in respect of matters arising under the Support Agreement). Voting and Exchange Trust Agreement Under the terms of the Voting and Exchange Trust Agreement, the Company will issue and grant to the Share Trustee the (i) rights of the holders of Exchangeable Shares to direct the voting of the 17 20 Voting Share in accordance with the Voting and Exchange Trust Agreement (the "Voting Rights"), and (ii) the Automatic Exchange Rights (as defined below) and the optional exchange right granted to the Share Trustee for the use and benefit of the holders of the Exchangeable Shares pursuant to the Voting and Exchange Trust Agreement to require the Company to purchase Exchangeable Shares from the holders thereof in exchange for shares of Common Stock upon the occurrence of a Pioneer Canada Insolvency Event (as defined herein). "Automatic Exchange Rights" means the rights granted to the Share Trustee for the benefit of the holders of the Exchangeable Shares pursuant to the Voting and Exchange Trust Agreement to automatically exchange the Exchangeable Shares for shares of Common Stock upon a Pioneer Liquidation Event (as defined herein). Voting Rights. Under the Voting and Exchange Trust Agreement, the Company will issue the Voting Share to the Share Trustee for the benefit of the holders (other than the Company and its subsidiaries) of the Exchangeable Shares. The Voting Share will have those voting rights with respect to the Company's Common Stock as previously discussed in "Description of Capital Stock--Special Preferred Voting Stock." Exchange Rights. Under the Voting and Exchange Trust Agreement, the Company will grant the Exchange Rights (as defined below) to the Trustee for the benefit of the holders of the Exchangeable Shares. "Exchange Rights" means the Automatic Exchange Rights and the optional exchange right granted to the Share Trustee for the use and benefit of the holders of the Exchangeable Shares pursuant to the Voting and Exchange Trust Agreement to require the Company to purchase Exchangeable Shares from the holders thereof in exchange for shares of Common Stock upon the occurrence of a Pioneer Canada Insolvency Event. Optional Exchange Right. Upon the occurrence and during the continuance of a Pioneer Canada Insolvency Event, a holder of Exchangeable Shares will be entitled to instruct the Share Trustee to exercise the optional Exchange Right with respect to any or all of the Exchangeable Shares held by such holder, thereby requiring the Company to purchase such Exchangeable Shares from the holder. Immediately upon the occurrence of a Pioneer Canada Insolvency Event or any event which may with the passage of time or the giving of notice become a Pioneer Canada Insolvency Event, Pioneer Canada and the Company will give written notice thereof to the Share Trustee. As soon as practicable thereafter, the Trustee will notify each holder of Exchangeable Shares of such event or potential event and will advise the holder of its rights with respect to the optional Exchange Right. "Pioneer Canada Insolvency Event" means any insolvency or bankruptcy proceeding instituted by or against Pioneer Canada, including any such proceeding under the Companies' Creditors Arrangement Act (Canada) and the Bankruptcy and Insolvency Act (Canada) and the admission in writing by Pioneer Canada of its inability to pay its debts generally as they become due and the inability of Pioneer Canada, as a result of solvency requirements of applicable law, to redeem any Exchangeable Shares tendered for redemption. The consideration for each Exchangeable Share to be acquired under the optional Exchange Right will be one share of Common Stock plus an additional amount equivalent to the full amount of all dividends declared and unpaid on the Exchangeable Share. If, as a result of liquidity or solvency provisions of applicable law, Pioneer Canada is unable to redeem all of the Exchangeable Shares tendered for redemption by a holder in accordance with the Exchangeable Share Provisions, the holder will be deemed to have exercised the optional Exchange Right with respect to the unredeemed Exchangeable Shares and the Company will be required to purchase such shares from the holder in the manner set forth above. Automatic Exchange Right. In the event of a Pioneer Liquidation Event, the Company will be required to acquire each outstanding Exchangeable Share by exchanging one share of Common Stock for each such Exchangeable Share, plus an additional amount equivalent to the full amount of all declared and unpaid dividends on the Exchangeable Shares. "Pioneer Liquidation Event" means: (i) any determination by the Company's Board of Directors to institute voluntary liquidation, dissolution or winding-up proceedings with respect to the Company or to effect any other distribution of assets of the Company among its stockholders for the purpose of winding up its affairs; or (ii) immediately upon the earlier of (A) receipt by the Company of notice of, and (B) the Company becoming aware of any threatened or instituted claim, suit, petition or other proceeding with respect to the involuntary liquidation, dissolution or winding-up of the Company or to effect any other distribution of assets of the Company among its stockholders for the purpose of winding- up its affairs. Delivery of Pioneer Common Stock The Company has agreed to ensure that all shares of Common Stock to be delivered by it under the Support Agreement or on the exercise of the Exchange Rights under the Voting and Exchange Trust Agreement are duly registered, qualified or approved under applicable Canadian and United States securities laws, if required so that such shares may be freely traded by the holder thereof (other than any restriction on transfer by reason of a holder being a "control person" of the Company for purposes of Canadian law or an "affiliate" of the Company for purposes of United States law). In addition, the Company will take all actions necessary to cause all such shares of Common Stock to be listed or quoted for trading on all stock exchanges or quotation systems on which outstanding shares of Common Stock are then listed or quoted for trading. 18 21 Call Rights The following section describes (i) the right of the Company, in the event of a proposed liquidation, dissolution or winding-up of Pioneer Canada, to purchase all of the outstanding Exchangeable Shares from the holders thereof on the effective date of any such liquidation, dissolution or winding-up in exchange for shares of Common Stock pursuant to the Plan of Arrangement (the "Liquidation Call Right"), (ii) the right of the Company to purchase all of the outstanding Exchangeable Shares from the holders thereof on the Automatic Redemption Date in exchange for shares of Common Stock pursuant to the Plan of Arrangement, and (iii) the overriding right of the Company, in the event of a proposed redemption of Exchangeable Shares by a holder thereof, to purchase from such holder on the redemption date the Exchangeable Shares tendered for redemption in exchange for shares of Common Stock pursuant to the Exchangeable Share Provisions. Optional Redemption By The Holders. Pursuant to the Exchangeable Share Provisions, a holder requesting Pioneer Canada to redeem the Exchangeable Shares will be deemed to offer such shares to the Company, and the Company will have an overriding redemption call right to acquire all but not less than all of the Exchangeable Shares that the holder has requested Pioneer Canada to redeem in exchange for one share of Common Stock for each Exchangeable Share, plus an additional amount equivalent to the full amount of all declared and unpaid dividends thereon. At the time of a redemption request by a holder of Exchangeable Shares, Pioneer Canada will immediately notify the Company. The Company must then advise Pioneer Canada within two business days as to whether the Company will exercise its redemption call right. If the Company does not advise Pioneer Canada within such two business day period, Pioneer Canada will notify the holder as soon as possible thereafter that the Company will not exercise its redemption call right. A holder may revoke his or her redemption request, at any time prior to the close of business on the business day preceding the redemption date, in which case the holder's Exchangeable Shares will neither be purchased by the Company nor redeemed by Pioneer Canada. If the holder does not revoke his or her redemption request, on the redemption date the Exchangeable Shares that the holder has requested Pioneer Canada to redeem will be acquired by the Company (assuming the Company exercises its redemption call right) or redeemed by Pioneer Canada, as the case may be, in each case for one share of Common Stock for each Exchangeable Share plus an additional amount equal to the full amount of all declared and unpaid dividends on the Exchangeable Shares. Liquidation Call Right. Pursuant to the Plan of Arrangement, the Company will be granted an overriding Liquidation Call Right, in the event of and notwithstanding a proposed Pioneer Canada Insolvency Event, to acquire all but not less than all of the Exchangeable Shares then outstanding in exchange for Common Stock and, upon the exercise by the Company of the Liquidation Call Right, the holders thereof will be obligated to transfer such shares to the Company. The acquisition by the Company of all of the outstanding Exchangeable Shares upon the exercise of the Liquidation Call Right will occur on the effective date of the voluntary or involuntary liquidation, dissolution or winding-up of Pioneer Canada. Optional Redemption By The Company. Pursuant to the Plan of Arrangement, the Company will be granted an overriding redemption call right, notwithstanding the proposed automatic redemption of the Exchangeable Shares by Pioneer Canada pursuant to the Exchangeable Share Provisions, to acquire on the Automatic Redemption Date all but not less than all of the Exchangeable Shares then outstanding in exchange for Common Stock plus an additional amount equal to the full amount of all declared and unpaid dividends on the Exchangeable Shares and, upon the exercise by the Company of the redemption call right, the holders thereof will be obligated to transfer such shares to the Company. Effect of Call Right Exercise. If the Company exercises one or more of its call rights, it will directly issue shares of Common Stock to holders of Exchangeable Shares and will become the holder of such Exchangeable Shares. The Company will not be entitled to exercise any voting rights attached to the Exchangeable Shares it so acquires. If the Company declines to exercise its call rights when applicable, it will be required, pursuant to the Support Agreement, to issue shares of Common Stock to Pioneer Canada which will, in turn, transfer such stock to the holders of Exchangeable Shares in consideration for the return and cancellation of such Exchangeable Shares. 19 22 DESCRIPTION OF DEPOSITARY SHARES The description set forth below and in any Prospectus Supplement of certain provisions of the Deposit Agreement (as defined below), Depositary Shares (as defined below) and Depositary Receipts (as defined below) does not purport to be complete and is subject to and qualified in its entirety by reference to the forms of Deposit Agreement and Depositary Receipts to each series of Preferred Stock that will be filed with the SEC in connection with the offering of the series of Preferred Stock. GENERAL The Company may, at its option, elect to offer fractional interests in shares of Preferred Stock, rather than shares of Preferred Stock. In the event such option is exercised, the Company will provide for the issuance by a depositary to the public of receipts for depositary shares ("Depositary Shares"), each of which will represent fractional interests of a particular series of Preferred Stock (which will be set forth in the Prospectus Supplement to a particular series of Preferred Stock). The shares of any series of Preferred Stock underlying the Depositary Shares will be deposited under a separate Deposit Agreement (the "Deposit Agreement") between the Company and a bank or trust company selected by the Company having its principal office in the United States and having a combined capital and surplus of at least $50 million. The Prospectus Supplement to a series of Depositary Shares will set forth the name and address of the depositary with respect to the Depositary Shares. Subject to the terms of the Deposit Agreement, each owner of Depositary Shares will be entitled, in proportion to the applicable fractional interests in shares of Preferred Stock underlying the Depositary Shares, to all the rights and preferences of the Preferred Stock underlying the Depositary Shares (including dividend, voting, redemption, conversion, and liquidation rights). The Depositary Shares will be evidenced by depositary receipts issued pursuant to the Deposit Agreement (the "Depositary Receipts"). Depositary Receipts will be distributed to those persons purchasing the fractional interests in shares of the related series of Preferred Stock in accordance with the terms of the offering described in the related Prospectus Supplement. DIVIDENDS AND OTHER DISTRIBUTIONS The depositary will distribute all cash dividends or other cash distributions received with respect to Preferred Stock to the record holders of Depositary Shares to the Preferred Stock in proportion to the numbers of the Depositary Shares owned by the holders on the relevant record date. The depositary shall distribute only the amount, however, as can be distributed without attributing to any holder of Depositary Shares a fraction of one cent, and the balance not so distributed shall be added to and treated as part of the next sum received by the depositary for distribution to record holders of Depositary Shares. In the event of a distribution other than in cash, the depositary will distribute property received by it to the record holders of Depositary Shares entitled thereto, unless the depositary determines that it is not feasible to make the distribution, in which case the depositary may, with the approval of the Company, sell the property and distribute the net proceeds from the sale to the holders. The Deposit Agreement will also contain provisions to the manner in which any subscription or similar rights offered by the Company to holders of the Preferred Stock shall be made available to the holders of Depositary Shares. REDEMPTION OF DEPOSITARY SHARES If a series of the Preferred Stock underlying the Depositary Shares is subject to redemption, the Depositary Shares will be redeemed from the proceeds received by the depositary resulting from the redemption, in whole or in part, of the series of the Preferred Stock held by the depositary. The depositary shall mail notice of redemption not less than 30 and not more than 60 days prior to the date fixed for redemption to the record holders of the Depositary Shares to be so redeemed at their respective addresses appearing in the depositary's books. The redemption price per Depositary Share will be equal to the applicable fraction of the redemption price per share payable with respect to the series of the Preferred Stock. Whenever the Company redeems shares of Preferred Stock held by the depositary, the depositary will redeem as of the same redemption date the number of Depositary Shares to shares of Preferred Stock so redeemed. If less than all the Depositary Shares are to be redeemed, the Depositary Shares to be redeemed will be selected by lot or pro rata as may be determined by the depositary. After the date fixed for redemption, the Depositary Shares so called for redemption will no longer be outstanding and all rights of the holders of the Depositary Shares will cease, except the right to receive the money, securities, or other property payable upon the redemption and any money, securities, or other property to which the holders of the Depositary Shares were entitled upon the redemption upon surrender to the depositary of the Depositary Receipts evidencing the Depositary Shares. 20 23 VOTING THE PREFERRED STOCK Upon receipt of notice of any meeting at which the holders of the Preferred Stock are entitled to vote, the depositary will mail the information contained in the notice of meeting to the record holders of the Depositary Shares to the Preferred Stock. Each record holder of the Depositary Shares on the record date (which will be the same date as the record date for the Preferred Stock) will be entitled to instruct the depositary as to the exercise of the voting rights pertaining to the number of shares of Preferred Stock underlying the holder's Depositary Shares. The depositary will endeavor, insofar as practicable, to vote the number of shares of Preferred Stock underlying the Depositary Shares in accordance with the instructions, and the Company will agree to take all action that may be deemed necessary by the depositary in order to enable the depositary to do so. AMENDMENT AND TERMINATION OF DEPOSITARY AGREEMENT The form of Depositary Receipt evidencing the Depositary Shares and any provision of the Deposit Agreement may at any time be amended by agreement between the Company and the depositary. However, any amendment that materially and adversely alters the rights of the existing holders of Depositary Shares will not be effective unless the amendment has been approved by the record holders of at least a majority of the Depositary Shares then outstanding. A Deposit Agreement may be terminated by the Company or the depositary only if (a) all outstanding Depositary Shares thereto have been redeemed or, (b) there has been a final distribution with respect to the Preferred Stock of the relevant series in connection with any liquidation, dissolution, or winding up of the Company and the distribution has been distributed to the holders of the related Depositary Shares. CHARGES OF DEPOSITARY The Company will pay all transfer and other taxes and governmental charges arising solely from the existence of the depositary arrangements. The Company will pay charges of the depositary in connection with the initial deposit of the Preferred Stock and any redemption of the Preferred Stock. Holders of Depositary Shares will pay transfer and other taxes and governmental charges and the other charges as are expressly provided in the Deposit Agreement to be for their accounts. RESIGNATION AND REMOVAL OF DEPOSITARY The depositary may resign at any time by delivering to the Company notice of its election to do so, and the Company may at any time remove the depositary, any such resignation or removal to take effect upon the appointment of a successor depositary and its acceptance of the appointment. The successor depositary must be appointed within 60 days after delivery of the notice of resignation or removal and must be a bank or trust company having its principal office in the United States and having a combined capital and surplus of at least $50 million. MISCELLANEOUS The depositary will forward to the holders of Depositary Shares all reports and communications from the Company that are delivered to the depositary and that the Company is required to furnish to the holders of the Preferred Stock. Neither the depositary nor the Company will be liable if it is prevented or delayed by law or any circumstance beyond its control in performing its obligations under the Deposit Agreement. The obligations of the Company and the depositary under the Deposit Agreement will be limited to performance in good faith of their duties thereunder and they will not be obligated to prosecute or defend any legal proceeding with respect to any Depositary Shares or Preferred Stock unless satisfactory indemnity is furnished. They may rely upon written advice of counsel or accountants, or information provided by persons presenting Preferred Stock for deposit, holders of Depositary Shares, or other persons believed to be competent and on documents believed to be genuine. DESCRIPTION OF WARRANTS The Company may issue Warrants for the purchase of Debt Securities, Preferred Stock or Common Stock. Warrants may be issued independently or together with Debt Securities, Preferred Stock or Common Stock offered by any Prospectus Supplement and may be attached to or separate from any such Offered Securities. Each series of Warrants will be issued under a separate warrant agreement (a "Warrant Agreement") to be entered into between the Company and a bank or trust company, as warrant agent (the "Warrant Agent"). The Warrant Agent will act solely as an agent of the Company in connection with the Warrants and will not assume any obligation or relationship of agency or trust for or with any holders or beneficial owners of Warrants.

PLAN OF DISTRIBUTION The Company may sell the Offered Securities within or outside the United States through underwriters, brokers or dealers, directly to one or more purchasers, or through agents. The Prospectus Supplement with respect to the Offered Securities will set forth the terms of the offering of the Offered Securities, including the name or names of any underwriters, dealers or agents, the purchase price of the Offered Securities and the proceeds to the Company from the sale, any delayed delivery arrangements, any underwriting discounts and other items constituting underwriters' compensation, the initial public offering price, any discounts or concessions allowed or reallowed or paid to dealers, and any securities exchanges on which the Offered Securities may be listed. If underwriters are used in the sale, the Offered Securities will be acquired by the underwriters for their own account and may be resold from time to time in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. The Offered Securities may be offered to the public either through underwriting syndicates represented by one or more managing underwriters or directly by one or more firms acting as underwriters. The underwriter or underwriters with respect to a particular underwritten offering of Offered Securities will be named in the Prospectus Supplement to the offering, and if an underwriting syndicate is used, the managing underwriter or underwriters will be set forth on the cover of the Prospectus Supplement. Unless otherwise set forth in the Prospectus Supplement thereto, the obligations of the underwriters or agents to purchase the Offered Securities will be subject to conditions precedent and the underwriters will be obligated to purchase all the Offered Securities if any are purchased. The initial public offering price and any discounts or concessions allowed or reallowed or paid to dealers may be changed from time to time. The Company may also sell the Offered Securities pursuant to one or more standby agreements with one or more underwriters in connection with the call for redemption of a specified class or series of any securities of the Company or any subsidiary of the Company. In such a standby agreement, the underwriter or underwriters would agree either (a) to purchase from 22 25 the Company up to the number of shares of Common Stock that would be issuable upon conversion of all the shares of the class or series of securities of the Company or its subsidiary at an agreed price per share of Common Stock, or (b) to purchase from the Company up to a specified dollar amount of Offered Securities at an agreed price per Offered Security which price may be fixed or may be established by formula or other method and which may or may not relate to market prices of the Common Stock or any other security of the Company then outstanding.

ITEM 15 -- INDEMNIFICATION OF DIRECTORS AND OFFICERS Article Twelfth of the Amended and Restated Certificate of Incorporation of the registrant provides that the registrant must indemnify its officers and directors to the extent allowed by the Delaware General Corporation Law. Pursuant to Section 145 of the Delaware General Corporation Law, the registrant generally has the power to indemnify its present and former directors and officers against expenses and liabilities incurred by them in connection with any suit to which they are, or are threatened to be made, a party by reason of their serving in those positions so long as they acted in good faith and in a manner they reasonably believed to be in, or not opposed to, the best interests of the registrant, and with respect to any criminal action, they had no reasonable cause to believe their conduct was unlawful. With respect to suits by or in the right of the registrant, however, indemnification is generally limited to attorneys' fees and other expenses and is not available if the person is adjudged to be liable to the registrant unless the court determines that indemnification is appropriate. The statute expressly provides that the power to indemnify authorized thereby is not exclusive of any rights granted under any by-law, agreement, vote of stockholders or disinterested directors, or otherwise. The registrant also has the power to purchase and maintain insurance for its directors and officers. Additionally, Article Twelfth of the Amended and Restated Certificate of Incorporation provides that, in the event that an officer or director files suit against the registrant seeking indemnification of liabilities or expenses incurred, the burden will be on the registrant to prove that the indemnification would not be permitted under the Delaware General Corporation Law. The registrant has entered into Indemnification Agreements with each of its directors and officers. These agreements provide that the registrant must indemnify an officer or director for liabilities incurred to the fullest extent permitted by the Delaware General Corporation Law. The registrant must, within ten days of a request, indemnify an officer or director for expenses incurred in the defense of a claim or other proceeding. The obligation of the registrant to provide the indemnification does not apply if, before the date on which the registrant must provide the indemnification, the registrant's Board of Directors, or a representative chosen by the Board of Directors, concludes that indemnification would be improper under the Delaware General Corporation Law. The preceding discussion of the registrant's Amended and Restated Certificate of Incorporation, Section 145 of the Delaware General Corporation Law, and the Indemnification Agreements is not intended to be exhaustive and is qualified in its entirety by the Amended and Restated Certificate of Incorporation, Section 145 of the Delaware General Corporation Law, and the Indemnification Agreements.

ITEM 17 -- UNDERTAKINGS The undersigned registrant hereby undertakes: (a) To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement. (1) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933 (the "Securities Act"); (2) To reflect in the prospectus any facts or events arising after the effective date of this Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in this Registration Statement; and (3) To include any material information with respect to the plan of distribution not previously disclosed in this Registration Statement or any material change to the information in this Registration Statement; Provided, however, that clauses (1) and (2) above do not apply if the information required to be included in a post-effective amendment by those clauses is contained in periodic reports filed by the registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference into this Registration Statement; (b) That, for the purpose of determining any liability under the Securities Act, each such post- effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of the securities at that time shall be deemed to be the initial bona fide offering thereof; and (c) To remove from registration by means of a post-effective amendment any of the securities being registered that remain unsold at the termination of the offering. The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the registrant's annual report pursuant to Section 13(a) or 15(d) of the Exchange Act that is incorporated by reference in this Registration Statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of the securities at that time shall be deemed to be the initial bona fide offering thereof. II-9 37 The undersigned registrant hereby undertakes to file an application for the purpose of determining the eligibility of the trustee to act under subsection (a) of Section 310 of the Trust Indenture Act ("Act") in accordance with the rules and regulations prescribed by the Commission under Section 305(b)(2) of the Act. Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers, and controlling persons of the registrant pursuant to the provisions described in Item 15 above or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer, or controlling person of the registrant in the successful defense of any action, suit, or proceeding) is asserted by the director, officer, or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of the issue. II-10 38 SIGNATURES Pursuant to the requirements of the Securities Act of 1933, the registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-3 and has duly caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in Irving, Texas, on December 12, 1997.

1.1      PLAN OF ARRANGEMENT
         As promptly as practicable after the execution of this Agreement,
Chauvco will apply to the Court of Queen's Bench of Alberta (the "Court")
pursuant to Part 15 of the Business Corporations Act (Alberta) (the "ABCA") for
an interim order (the "Interim Order") providing for, among other things, the
calling and holding of the Chauvco Meeting (as hereinafter defined) for the
purpose of considering and, if deemed advisable, approving the arrangement (the
"Arrangement") under Part 15 of the ABCA and pursuant to this Agreement and the
Plan of Arrangement substantially in the form of Exhibit A hereto (the "Plan of
Arrangement"). If the Chauvco shareholders approve the Arrangement, thereafter
Chauvco will take the necessary steps to submit the Arrangement to the Court
and apply for a final order of the Court approving the Arrangement in such
fashion as the Court may direct (the "Final Order") and file Articles of
Arrangement in respect of the Arrangement. At 12:01 a.m. (the "Effective Time")
on the date (the "Effective Date") shown on the certificate of arrangement
issued by the Registrar under the ABCA giving effect to the Arrangement (which
shall be within 60 days after the date of the Final Order), the following shall
occur and shall be deemed to occur in the following order without any further
act or formality:
         (a) Chauvco shall subscribe for that number of common shares in the
capital of Chauvco Resources International Ltd. ("CRI") as is equal to (i) the
number of common shares of Chauvco (the "Chauvco Common Shares") which are
issued and outstanding three trading days prior to the Effective Date (the
"Record Date"), (ii) plus that number of Chauvco Common Shares which all
Optionholders (as hereinafter defined) would otherwise be entitled to acquire
on the exercise of their Chauvco Options (as hereinafter defined) on a fully
vested basis on the Record Date (other than Chauvco Common Shares that could be
acquired by Optionholders who exercise their right of dissent in accordance
with the Interim Order and who are ultimately entitled to be paid the fair
value of their Chauvco Options), (iii) less that number of common shares of CRI
then held by Chauvco, and (iv) less that number of Chauvco Common Shares held
by shareholders who have exercised their rights of dissent in accordance with
the Interim Order and who are ultimately entitled to be paid the
   2
                                     - 2 -
fair value for such shares. The subscription price for the common shares of CRI
shall be paid for in cash in the aggregate amount equal to US$5,000,000 plus
the fair market value on the Effective Date (as determined and adjusted in
accordance with Section 7.7) of the Gabon Securities (as hereinafter defined);
         (b) CRI shall purchase from CR International Limited ("CR"), a
wholly-owned subsidiary of Chauvco, for cash in an aggregate amount equal to
the fair market value thereof on the Effective Date (as determined and adjusted
in accordance with Section 7.7), (i) all of the issued and outstanding
securities of Chauvco Resources (Gabon) S.A., Chauvco Resources (Gabon-Ngalo)
S.A., Chauvco Resources (Gabon-Maga) S.A., Chauvco Resources (Gabon-Avomo) S.A.
and CR Trading Co. Ltd. (collectively, the "Gabon Subsidiaries"), (ii) 75% of
the issued and outstanding securities of Westoil Marine & Transport Co. Ltd.
("Westoil"), and (iii) all of its rights under a loan in the amount of U.S.
$909,421.60 made by CR to Olympic Marine Services International, Inc. (which
owns the remaining 25% of the issued and outstanding securities of Westoil),
any and all advances made by CR to Westoil, and any and all advances made by
Chauvco (all of which shall have first been assigned by Chauvco to CR) to the
Gabon Subsidiaries and Westoil (such securities in Section 1.1(b)(i), (ii) and
(iii) collectively, the "Gabon Securities");
         (c) Chauvco shall transfer, assign and convey to CRI, in consideration
for $1.00, all of Chauvco's right, title, benefit and interest in and to any
and all trademarks (including registrations and applications therefor), trade
names and the internet domain name "chauvco.com" owned by Chauvco as at the
Effective Time, and the other assets and property which are set out in Exhibit
F;
         (d) US Co Sub (as hereinafter defined) shall purchase from Chauvco all
of the issued and outstanding common shares of CRI (the "CRI Shares") in
consideration of the payment by way of promissory note of US Co Sub to Chauvco
in an amount equal to the subscription price paid for such CRI Shares by
Chauvco under Section 1.1(a);
         (e) each of the outstanding options to purchase Chauvco Common Shares
other than options held by a holder who has exercised its right of dissent in
accordance with the Interim Order and is ultimately entitled to be paid the
fair value of its options (collectively, the "Chauvco Options") (which includes
all outstanding options granted under Chauvco's stock option plan as amended
and restated on November 10, 2021 (the "Chauvco Option Plan")) will vest, if
not already vested, and be transferred to US Co Sub in consideration for one
(1) CRI Share and, in accordance with the election of each holder thereof (the
"Optionholder") and the remainder of this Section 1.1(e) and Section 1.1(f), a
number of shares of US Co common stock ("US Co Common Stock") determined in
accordance with the Exchange Ratio (as hereinafter defined) in which event, in
addition to transferring the Chauvco Options to US Co Sub, the Optionholder
will be required to make a payment to US Co Sub (the "Option Payment") in an
amount equal to the aggregate exercise price which the Optionholder would
otherwise be required to pay on the exercise of such options. As an alternative
to making the Option Payment, Optionholders will be entitled to elect to reduce
the number of shares of US Co Common Stock to be received by the number
obtained by dividing the Option Payment by the US Co Stock Price, as defined in
Section 1.3 (converted into Canadian dollars using the Currency Exchange Rate
(as hereinafter defined)). Each Optionholder will receive only a whole number
of shares of US Co Common Stock resulting from the transfer of his Chauvco
Options. In lieu of fractional shares of US Co Common Stock, each Optionholder
who would otherwise be entitled to receive such fractional shares shall be paid
by US Co Sub an amount
   3
                                     - 3 -
determined in accordance with the Plan of Arrangement in full satisfaction of
such fractional entitlement;
         (f) an Optionholder electing to make the Option Payment and receive
the applicable number of shares of US Co Common Stock under Section 1.1(e)
above shall give effect to the election by depositing with Montreal Trust
Company of Canada (the "Depositary"), prior to the date which is two (2) days
prior to the date of the Chauvco Meeting (the "Election Deadline"), a duly
completed letter of transmittal and election form (the "Option Letter of
Transmittal and Election Form") in the form provided by Chauvco along with the
proxy materials indicating such holder's election and by agreeing to pay the
Option Payment to the Depositary as agent for US Co Sub. Coincident with the
receipt of the CRI Shares and shares of US Co Common Stock, such Optionholder
shall pay the Option Payment to the Depositary as agent for US Co Sub less any
amounts receivable by such Optionholder in connection with fractional
entitlements under the Plan of Arrangement. In the event that an Optionholder
who has elected to make the Option Payment fails to make the Option Payment on
or before the day that is 60 days after the Effective Date, such Optionholder
shall be deemed to have elected the option to receive the reduced number of
shares of US Co Common Stock by not making the Option Payment. In the event
that an Optionholder has failed to validly make an election in the Option
Letter of Transmittal and Election Form pursuant to this paragraph, such
Optionholder shall be deemed to have elected the option to receive the reduced
number of shares of US Co Common Stock by not making the Option Payment;
         (g) each of the outstanding Chauvco Common Shares that are not held by
a shareholder who has exercised its right of dissent in accordance with the
Interim Order and is ultimately entitled to be paid the fair value of its
Chauvco Common Shares will be transferred to US Co Sub in consideration for one
(1) CRI Share and, at the election of the holders of the Chauvco Common Shares:
                  (i)      a number of shares of US Co Common Stock determined
                           in accordance with the Exchange Ratio. Each such
                           holder of Chauvco Common Shares will receive only a
                           whole number of shares of US Co Common Stock
                           resulting from the transfer of such holder's Chauvco
                           Common Shares to US Co Sub. In lieu of fractional
                           shares of US Co Common Stock, each holder of a
                           Chauvco Common Share who otherwise would be entitled
                           to receive such fractional share shall be paid by US
                           Co Sub an amount determined in accordance with the
                           Plan of Arrangement in full satisfaction of such
                           fractional entitlement; or
                  (ii)     a number of shares of Exchangeable Shares determined
                           in accordance with the Exchange Ratio. Each such
                           holder of Chauvco Common Shares will receive only a
                           whole number of Exchangeable Shares resulting from
                           the transfer of such holder's Chauvco Common Shares
                           to US Co Sub. In lieu of fractional Exchangeable
                           Shares, each holder of a Chauvco Common Share who
                           otherwise would be entitled to receive such
                           fractional share shall be paid by US Co Sub an
                           amount determined in accordance with the Plan of
                           Arrangement in full satisfaction of such fractional
                           entitlement;

                                     - 4 -
                           provided that such holders shall be entitled to elect
                           to receive a combination of shares of US Co Common 
                           Stock and Exchangeable Shares on the transfer of 
                           their Chauvco Common Shares;
         (h) a holder of Chauvco Common Shares shall give effect to the
election in Section 1.1(g) above by depositing with the Depositary, prior to
the Election Deadline, a duly completed letter of transmittal and election form
(the "Letter of Transmittal and Election Form") in the form provided by Chauvco
along with the proxy materials indicating such holder's election. In the event
that a holder of Chauvco Common Shares has failed to validly make an election
under Section 1.1(g) in the Letter of Transmittal and Election Form pursuant to
this paragraph, such holder shall be deemed to have elected the option under
Section 1.1(g)(i). Notwithstanding any provision to the contrary, holders of
Chauvco Common Shares who are not residents of Canada for the purposes of the
Income Tax Act (Canada) (the "ITA") will not be entitled to elect to receive
Exchangeable Shares under Section 1.1(g)(ii);
         (i) upon the transfer of shares referred to in Section 1.1(g) above:
(i) each holder of a Chauvco Common Share shall cease to be such a holder,
shall have his name removed from the register of holders of Chauvco Common
Shares and shall become a holder of the number of fully paid CRI Shares and
Exchangeable Shares and/or shares of US Co Common Stock to which he is entitled
as a result of the transfer of shares referred to in Section 1.1(g) and such
holder's name shall be added to the register of holders of such securities
accordingly; and (ii) US Co Sub shall become the legal and beneficial owner of
all of the Chauvco Common Shares so transferred;
         (j) holders of Chauvco Common Shares who are residents of Canada for
the purposes of the ITA and who have elected to receive Exchangeable Shares
under Section 1.1(g)(ii) above shall be entitled to make an income tax election
pursuant to subsection 85(1) of the ITA with respect to the transfer of their
Chauvco Common Shares to US Co Sub referred to in Section 1.1(g)(ii) by
providing two signed copies of the necessary election forms to US Co Sub within
90 days following the Effective Date, duly completed with the details of the
number of shares transferred and the applicable agreed amounts for the purposes
of such elections. Thereafter, subject to the election forms complying with the
provisions of the ITA, the forms will be signed by US Co Sub and returned to
such holders of Chauvco Common Shares for filing with Revenue Canada, Customs,
Excise and Taxation;
         (k) US Co shall issue to and deposit with the Depositary the Voting
Share (as defined in the Voting and Exchange Trust Agreement (as defined
herein)), in consideration of the payment to US Co of US $1, to be hereafter
held of record by the Depositary as trustee for and on behalf of, and for the
use and benefit of, the holders of the Exchangeable Shares, in accordance with
the Voting and Exchange Trust Agreement; and
         (l) US Co Sub shall be continued as a corporation under the ABCA and
its Articles of Continuance shall include the items set forth in Exhibit G.
1.2      US CO SUB
         (a) On or prior to the Effective Date, US Co shall (directly or
through a wholly-owned subsidiary incorporated in the United States)
incorporate a new corporation under the Company Act
   5
                                     - 5 -
(British Columbia) ("US Co Sub") to be named Pioneer Natural Resources (Canada)
Ltd. and shall include the following provisions in its memorandum of
association (or as may be amended by mutual agreement on the advice of outside
counsel to comply with the Company Act):
                  (i)      a class of common voting shares (the "US Co Sub
                           Common Shares") unlimited in number;
                  (ii)     a class of exchangeable shares (the "Exchangeable
                           Shares") unlimited in number; and
                  (iii)    a restriction on the business of US Co Sub;
all as set out in Exhibit G and, in connection with such incorporation, US Co
shall (directly or through a wholly-owned subsidiary incorporated in the United
States) cause US Co Sub to purchase from US Co that number of newly issued
shares of US Co Common Stock which will enable US Co Sub to satisfy its
obligation to deliver US Co Common Stock to holders of Chauvco Common Shares
and to Optionholders who transfer their Chauvco Common Shares or Chauvco
Options to US Co Sub under Sections 1.1(g)(i) and 1.1(e) above.
         (b) US Co shall cause US Co Sub to complete the transactions
contemplated herein.
1.3      EXCHANGE RATIO
                  As used herein, the term "Exchange Ratio" means in respect of
Exchangeable Shares or US Co Common Stock to be delivered upon the transfer of
Chauvco Common Shares or Chauvco Options to US Co Sub, a ratio of the number of
Exchangeable Shares or shares of US Co Common Stock per Chauvco Common Share or
Chauvco Option equal to:
         (a)      if the US Co Stock Price is less than US$33.50, (.493827);
         (b)      if the US Co Stock Price is at least US$33.50 but less than
US$39.01,
                  .493827 - ((US Co Stock Price - 33.50) X .042360)
                                         5.51
                  and
         (c)      if the US Co Stock Price is equal to or greater than $39.01,
(.451467).
The Exchange Ratio as so determined in each case shall be rounded to six
decimal places. The "US Co Stock Price" shall mean the average closing sales
price, regular way, per share of the US Co Common Stock on the NYSE in United
States dollars as reported in the Wall Street Journal over the ten (10)
consecutive trading days ending on the third trading day next preceding the
date of the Chauvco Meeting. Notwithstanding the foregoing, if the Exchange
Ratio is above .465116, US Co may elect to cause US Co Sub to deliver, in lieu
of Exchangeable Shares and shares of US Co Common Stock, a number of
Exchangeable Shares or shares of US Co Common Stock for each Chauvco Common
Share or Chauvco Option based on the Exchange Ratio as set forth above equal
   6
                                     - 6 -
to (.465116) and an amount in cash (in Canadian dollars) per Chauvco Common
Share or Chauvco Option equal to the product of (x) the US Co Stock Price
multiplied by the noon spot rate of exchange of US dollars to Canadian dollars
announced by the Bank of Canada on the day preceding the date of calculation
for the exchange (the "Currency Exchange Rate") and (y)
                           Exchange Ratio -- .465116
1.4      ADJUSTMENTS FOR CAPITAL CHANGES
         Prior to the Effective Time, Chauvco shall not recapitalize through a
subdivision of its outstanding shares into a greater number of shares, or a
combination of its outstanding shares into a lesser number of shares, or
reorganize, reclassify or otherwise change its outstanding shares into the same
or a different number of shares of other classes, or declare a dividend on its
outstanding shares payable in shares of its capital stock or securities
convertible or exchangeable into shares of its capital stock. Prior to the
Effective Time, US Co may with prior written consent of Chauvco recapitalize
through a subdivision of its outstanding shares into a greater number of
shares, or a combination of its outstanding shares into a lesser number of
shares, or reorganize, reclassify or otherwise change its outstanding shares
into the same or a different number of shares of other classes, or declare a
dividend on its outstanding shares payable in shares of its capital stock or
securities convertible or exchangeable into shares of its capital stock,
provided that, in connection therewith the Exchange Ratio shall be adjusted
appropriately so as to maintain the relative proportionate interests of the
holders of Chauvco Common Shares and the holders of the shares of US Co Common
Stock and provided further that, the consent of Chauvco may not be withheld if
the foregoing proviso is complied with. No such changes shall be made by US Co
other than those made in accordance with this Agreement.
1.5      DISSENTING SHAREHOLDERS
         Holders of Chauvco Common Shares may exercise rights of dissent with
respect to such shares in connection with the Arrangement pursuant to and in
the manner set forth in Section 184 of the ABCA and Section 3.1 of the Plan of
Arrangement (such holders referred to as "Dissenters" or as "Dissenting
Shareholders"). Chauvco shall give US Co (i) prompt notice of any written
demands of a right of dissent, withdrawals of such demands, and any other
instruments served pursuant to the ABCA and received by Chauvco and (ii) the
opportunity to participate in all negotiations and proceedings with respect to
such rights. Without the prior written consent of US Co, except as required by
applicable law, Chauvco shall not make any payment with respect to any such
rights or offer to settle or settle any such rights. The obligations in respect
of Dissenting Shareholders shall be apportioned between Chauvco and CRI as set
forth in the Plan of Arrangement.
1.6      OTHER EFFECTS OF THE ARRANGEMENT
         The Arrangement will, from and after the Effective Time, have all of
the effects provided by applicable law, including, without limitation, the
ABCA.

1.7      JOINT PROXY STATEMENT; FORM F-4, FORM S-4 AND FORM S-3 REGISTRATION 
         STATEMENT
         (a) As promptly as practicable after execution of this Agreement, US
Co and Chauvco shall prepare and file with the United States Securities and
Exchange Commission (the "SEC") a preliminary joint management information
circular and proxy statement (the "Joint Proxy Statement"), together with any
other documents required by the Securities Act of 1933, as amended (the
"Securities Act"), or the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), in connection with the Arrangement and the other transactions
contemplated hereby. The Joint Proxy Statement shall constitute (i) the
management information circular of Chauvco with respect to the meeting of
shareholders of Chauvco relating to the Arrangement and the approval of certain
matters in connection therewith (the "Chauvco Meeting") and (ii) the proxy
statement of US Co with respect to the meeting of stockholders of US Co with
respect to the issuance of US Co Common Stock from time to time upon exchange
of Exchangeable Shares and any other matters requiring approval of such
stockholders in connection with the Arrangement (the "US Co Stockholders
Meeting"). As promptly as practicable after the preliminary Joint Proxy
Statement is cleared by the SEC, US Co and Chauvco shall cause the Joint Proxy
Statement to be mailed to each company's respective stockholders. If either
Chauvco or US Co determines on the advice of its outside counsel (with the
concurrence of outside counsel for the other) that the offer and sale of the
Exchangeable Shares or the CRI Shares in connection with the Arrangement is
required to be registered under the Securities Act, then as applicable, US Co
shall cause US Co Sub to file with the SEC a registration statement on Form S-4
(or other applicable form) (such registration statement, the "Form S-4") and if
it is determined that the offer and sale of the CRI Shares is not otherwise
exempt from such registration, Chauvco and US Co shall (a) agree on appropriate
and equitable adjustments to the Plan of Arrangement so that CRI Shares that
would otherwise be issued to holders who are residents of the United States
shall instead be sold by a trustee or agent and the net proceeds of such sales
remitted to such holders and otherwise as may be necessary to avoid offers and
sales of the CRI Shares being deemed to take place within the United States, if
such adjustments will avoid the necessity for such registration or (b) if such
adjustments cannot reasonably be undertaken so as to avoid the necessity for
such registration, Chauvco shall cause CRI to file with the SEC a registration
statement on Form F-4 (or other applicable form) covering such offer and sale
(such registration statement, the "Form F-4") and the Joint Proxy Statement
shall also constitute the prospectuses of US Co Sub and CRI, as applicable,
with respect to such offer and sale and shall be included in the Form S-4 or
Form F-4, as applicable. Notwithstanding anything herein to the contrary,
neither Chauvco nor US Co shall be under any obligation to cause to be filed
the Form S-4 or Forms F-4 if it shall have determined on the advice of its
outside counsel (with the concurrence of outside counsel for the other) that
the offer and sale of the Exchangeable Shares and the CRI Shares pursuant to
the Arrangement is exempt from the registration requirements of Section 5 of
the Securities Act by virtue of Section 3(a)(10) thereof. In connection with
such determination, US Co and Chauvco shall prepare and file with the SEC a
request for no action (the "No Action Request") seeking to confirm the
availability of such exemption. If US Co determines on the advice of its
outside counsel (with the concurrence of outside counsel for Chauvco) that it
is necessary to file a registration statement on Form S-3 (or other applicable
form)(the "Form S-3") in order to register the US Co Common Stock to be issued
from time to time after the Effective Time upon exchange of the Exchangeable
Shares, then US Co shall file the Form S-3 with the SEC and use its best
efforts to maintain the effectiveness of such registration for the period that
such Exchangeable Shares remain outstanding, and US Co and Chauvco shall use
their best efforts to cause the Form S-3 to become effective.

         (b) Each party shall promptly furnish to the other party all
information concerning such party and its stockholders as may be reasonably
required in connection with any action contemplated by this Section 1.5. The
Joint Proxy Statement and, if required, the Form F-4, Form S-4 and Form S-3,
shall comply in all material respects with all applicable requirements of law.
Each of US Co and Chauvco will notify the other promptly of the receipt of any
comments from the SEC and of any request by the SEC for amendments or
supplements to the Joint Proxy Statement or the Form F-4, Form S-4 or Form S-3,
if required, or for additional information, and will supply the other with
copies of all correspondence with the SEC with respect to the Joint Proxy
Statement or the Form S-3, if required. Whenever any event occurs which should
be set forth in an amendment or supplement to the Joint Proxy Statement or the
Form F-4, Form S-4 or Form S-3, if required, US Co or Chauvco, as the case may
be, shall promptly inform the other of such occurrence and cooperate in filing
with the SEC, and/or mailing to stockholders of US Co or Chauvco, as may be
applicable, such amendment or supplement.
         (c) US Co and Chauvco shall take any action required to be taken under
any applicable provincial or state securities laws (including "blue sky" laws)
in connection with the issuance of the Exchangeable Shares, CRI Shares or US Co
Common Stock and the Arrangement; provided, however, that with respect to the
blue sky and Canadian provincial qualifications, neither US Co nor Chauvco
shall be required to register or qualify as a foreign corporation or reporting
issuer where any such entity is not now so registered or qualified except as to
matters and transactions arising solely from the offer and sale of the US Co
Common Stock, the CRI Shares or the issuance of the Exchangeable Shares.
1.8      REORGANIZATION
         The parties intend to adopt this Agreement and the Plan of Arrangement
as a qualified stock purchase under Section 338(d)(3) of the Internal Revenue
Code of 1986, as amended (the "Code").
1.9      MATERIAL ADVERSE EFFECT
         In this Agreement, any reference to any event, change or effect being
"material" with respect to any entity or group of entities means any material
event, change or effect related to the condition (financial or otherwise),
properties or business of such entity or group of entities. In this Agreement,
the term "Material Adverse Effect" used with respect to any party means any
event, change or effect that is materially adverse to the condition (financial
or otherwise), properties or business of such party and its subsidiaries, taken
as a whole; provided, that a Material Adverse Effect shall not include any
adverse effect resulting from changes in general economic conditions or
conditions generally affecting the industries in which US Co or Chauvco
operate.
1.10     CURRENCY
         Unless otherwise specified, all references in this Agreement to

         Except as set forth in a letter dated the date of this Agreement and
delivered by Chauvco to US Co concurrently herewith (the "Chauvco Disclosure
Letter") and subject to Sections 7.7 and 7.8 hereof, Chauvco hereby represents
and warrants to US Co that:
2.1      ORGANIZATION AND STANDING
         Chauvco and each partnership, joint venture, corporation, association
or other business entity of which more than 50% of the total voting power of

existing and in good standing under the laws of the jurisdiction of its
incorporation or formation, has full requisite power and authority to carry on
its business as it is currently conducted, and to own, lease and operate the

licensed to do business and is in good standing as a foreign corporation or

character of the properties owned or leased or the nature of the business

where the failure to be so qualified or licensed would not have a Material
Adverse Effect on Chauvco. The Chauvco Disclosure Letter sets forth a complete
list of the Chauvco Subsidiaries (and all other subsidiaries in which Chauvco

of each subsidiary's outstanding capital stock or other ownership interest
owned by Chauvco or another Chauvco Subsidiary and a description of any lien,

delivery of this Agreement by Chauvco and, subject to approval of this
Agreement and the Arrangement by the shareholders of Chauvco and approval by
the Court, the consummation by Chauvco of the Arrangement and the other
transactions contemplated hereby have been duly authorized by all necessary
corporate action on the part of Chauvco. This Agreement has been duly executed

be subject to (i) bankruptcy, insolvency, reorganization or other similar laws
affecting or relating to enforcement of creditors' rights generally and (ii)
general equitable principles.
         (b) Neither the execution, delivery and performance of this Agreement
or the Arrangement by Chauvco, nor the consummation of the transactions

decree, statute, law, ordinance, rule or regulation applicable to Chauvco or
any of the Chauvco Subsidiaries or their respective properties or assets, other

or in the aggregate, would not have a Material Adverse Effect on Chauvco.
2.3      GOVERNMENTAL CONSENTS
         No consent, approval, order or authorization of, or registration,
declaration or filing with, any court, administrative agency or commission or
other governmental authority or instrumentality, domestic or foreign (each a
"Governmental Entity"), is required to be obtained by Chauvco or any of the
Chauvco Subsidiaries in connection with the execution and delivery of this
Agreement or the Plan of Arrangement or the consummation of the transactions
contemplated hereby or thereby, except for: (i) the filing with the applicable

                                     - 11 -
the Arrangement or otherwise prevent Chauvco from performing its obligations

2.4      CAPITALIZATION
         The authorized capital stock of Chauvco consists of an unlimited
number of Chauvco Common Shares, no par value. At the close of business on
August 29, 1997, 48,464,312 Chauvco Common Shares were issued and outstanding,
and no Chauvco Common Shares were held by Chauvco in its treasury. As of August
29, 1997, an aggregate of 2,901,995 Chauvco Common Shares were reserved for
issuance pursuant to outstanding Chauvco Options granted under the Chauvco
Option Plan. All issued and outstanding Chauvco Common Shares have been duly
authorized, validly issued and are fully paid and non-assessable. Except in
connection with the Chauvco Option Plan and in connection with Chauvco's
shareholder rights plan adopted pursuant to that agreement dated April 24, 2022
between Chauvco and Montreal Trust Company of Canada (the "Chauvco SRP"), no
person, firm or corporation has any agreement or option or any right or
privilege, whether by law, pre-emptive or contractual, capable of becoming an
agreement, including convertible securities, warrants or convertible
obligations of any nature, for the purchase, subscription, allotment or
issuance of any of the unissued shares in the capital of Chauvco or of any
securities of Chauvco.
2.5      SECURITIES REPORTS AND FINANCIAL STATEMENTS
         Chauvco and all predecessor corporations to Chauvco have filed all
forms, reports and documents with the Commissions required to be filed by it or
them pursuant to relevant Canadian securities statutes, regulations, policies
and rules (collectively, the "Chauvco Securities Reports"), all of which have
complied in all material respects with all applicable requirements of such
statutes, regulations, policies and rules. None of the Chauvco Securities
Reports, at the time filed or as subsequently amended, contained any untrue
statement of a material fact or omitted to state a material fact required to be
stated therein or necessary in order to make the statements made therein, in
light of the circumstances under which they were made, not misleading. The
financial statements of Chauvco and such predecessor corporations contained in
the Chauvco Securities Reports complied in all material respects with the then
applicable accounting requirements and the published rules and regulations of
the relevant Canadian securities statutes with respect thereto, were prepared
in accordance with Canadian generally accepted accounting principles applied on
a consistent basis during the periods involved (except as may have been
indicated in the notes thereto or, in the case of unaudited statements, as
permitted by applicable laws, rules or regulations) and fairly present
(subject, in the case of the unaudited statements, to normal, year-end audit
adjustments) the consolidated financial position of Chauvco and such
predecessor corporations and the consolidated Chauvco Subsidiaries as at the
respective dates thereof and the consolidated results of their operations and
cash flows for the respective periods then ended. There has been no change in
the accounting policies or the methods of making accounting estimates of
Chauvco or its predecessor corporations or changes in estimates that are
material to such financial statements, except as described in the notes
thereto.

obligations, either accrued, absolute, contingent, or otherwise, or have any
knowledge of any potential liabilities or obligations, other than those (i)
disclosed in the Chauvco Securities Reports, (ii) set forth in the Chauvco
Disclosure Letter, (iii) incurred in the ordinary course of business since June
30, 1997; or (iv) which individually or in the aggregate would not reasonably
be expected to have a Material Adverse Effect on Chauvco.
2.7      INFORMATION SUPPLIED
         None of the information supplied or to be supplied by Chauvco for
inclusion or incorporation by reference in the Joint Proxy Statement (and, if
filed, the Form S-3, S-4 or F-4) will, at the time the Joint Proxy Statement is
mailed to the shareholders of Chauvco and at the time of the Chauvco Meeting
(and, if filed, at the time the Form S-3, S-4 or F-4 is declared effective),
contain any untrue statement of a material fact or omit to state any material
fact required to be stated therein or necessary to make the statements therein,
in light of the circumstances under which they are made, not misleading. The
Joint Proxy Statement will comply as to form in all material respects with the
provisions of the ABCA and applicable Canadian securities laws and the rules
and regulations promulgated thereunder.
2.8      NO DEFAULTS
         Neither Chauvco nor any Chauvco Subsidiary is, or has received notice

judgment, decree or order applicable to it; or (iii) any loan or credit
agreement, note, bond, mortgage, indenture, material contract, agreement,
lease, license or other instrument to which Chauvco or any Chauvco Subsidiary
is now a party or by which it or any of its properties or assets may be bound,
except in the case of item (iii) for defaults and violations which,
individually or in the aggregate, would not have a Material Adverse Effect on
Chauvco.
2.9      LITIGATION; INVESTIGATIONS
         There is no claim, action, suit or proceeding pending or, to the
knowledge of Chauvco, threatened, which would, if adversely determined,
individually or in the aggregate, have a Material Adverse Effect on Chauvco,
nor is there any judgment, decree, injunction, rule or order of any
Governmental Entity or arbitrator outstanding against Chauvco or any of the
Chauvco Subsidiaries having, or which, insofar as reasonably can be foreseen,
in the future could have, any such effect. There is no investigation pending
or, to the knowledge of Chauvco, threatened, against Chauvco or any of the
Chauvco Subsidiaries before any Governmental Entity which could have any such
effect.

3.2      AGREEMENT AUTHORIZED AND ITS EFFECT ON OTHER OBLIGATIONS

ordinance, rule or regulation applicable to US Co or any of the US Co
Subsidiaries or their respective properties or assets, other than any such

Effect on US Co.
3.4      CAPITALIZATION
         The authorized capital stock of US Co consists of 500,000,000 common
shares, U.S.$0.01 par value ("US Co Common Stock") and 100,000,000 preferred

   20
                                     - 20 -
Preferred Stock"). As of August 29, 1997, there were 73,555,501 shares of US Co
Common Stock outstanding, and 3,718,314 shares of US Co Common Stock were
reserved for issuance upon the exercise of stock options outstanding under US
Co's stock option plan; at the same date, no shares of US Co Preferred Stock
were outstanding. Except in connection with US Co's stock option plan, no
person, firm or corporation has any agreement or option or any right or
privilege, whether by law, pre-emptive or contractual, capable of becoming an
agreement, including convertible securities, warrants or convertible
obligations of any nature, for the purchase, subscription, allotment or
issuance of any of the unissued shares in the capital of US Co or of any
securities of US Co. US Co has no shareholder rights plan or similar
arrangement in place in connection with the US Co Common Stock or otherwise
(provided that US Co shall be entitled to institute such a plan or similar
arrangement prior to the Effective Date so long as such plan treats the holders
of Exchangeable Shares in substantially the same manner as the holders of US Co
Common Stock and provided the institution of the shareholder rights plan does
not have a tax impact on the holders of Exchangeable Shares.
3.5      SECURITIES REPORTS AND FINANCIAL STATEMENTS
         US Co and all predecessor corporations to US Co have filed all forms,
reports and documents required to be filed by them by the SEC or pursuant to
relevant United States securities statutes, regulations, policies and rules
(collectively, the "US Co Securities Reports"), all of which have complied in
all material respects with all applicable requirements of such statutes,
regulations, policies and rules. None of the US Co Securities Reports, at the
time filed or as subsequently amended, contained any untrue statement of a
material fact or omitted to state a material fact required to be stated therein
or necessary in order to make the statements made therein, in light of the
circumstances under which they were made, not misleading. The financial
statements of US Co and such predecessor corporations contained in the US Co
Securities Reports complied in all material respects with the then applicable
accounting requirements and the published rules and regulations of the relevant
United States securities statutes with respect thereto, were prepared in
accordance with United States generally accepted accounting principles applied
on a consistent basis during the periods involved (except as may have been
indicated in the notes thereto or, in the case of unaudited statements, as
permitted by applicable laws, rules or regulations) and fairly present
(subject, in the case of the unaudited statements, to normal, year-end audit
adjustments) the consolidated financial position of US Co and such predecessor
corporations and the consolidated US Co Subsidiaries as at the respective dates
thereof and the consolidated results of their operations and cash flows for the
respective periods then ended. There has been no change in the accounting
policies or the methods of making accounting estimates or changes in estimates
of US Co or its predecessor corporations that are material to such financial
statements, except as described in the notes thereto.
3.6      LIABILITIES
         US Co and the US Co Subsidiaries do not have any liabilities or
obligations, either accrued, absolute, contingent, or otherwise, or have any
knowledge of any potential liabilities or obligations, other than those (i)
disclosed in the US Co Securities Reports or those of its predecessors, (ii)
set forth in the US Co Disclosure Letter, (iii) incurred in the ordinary course
of business since June 30, 1997, or (iv) which individually or in the aggregate
would not reasonably be expected to have a Material Adverse Effect on US Co.

3.7      INFORMATION SUPPLIED
         None of the information supplied or to be supplied by US Co for
inclusion or incorporation by reference in the Joint Proxy Statement (and, if
filed, the Form F-4 or Form S-3) will, at the time the Joint Proxy Statement is
mailed to the shareholders of US Co and at the time of the US Co Stockholders
Meeting (and, if filed, at the time the Form F-4 or Form S-3 is declared
effective), contain any untrue statement of a material fact or omit to state
any material fact required to be stated therein or necessary to make the
statements therein, in light of the circumstances under which they are made,
not misleading. The Joint Proxy Statement will comply as to form in all
material respects with the provisions of applicable United States securities
laws and the rules and regulations of the SEC.
3.8      NO DEFAULTS
         Neither US Co nor any US Co Subsidiary is, or has received notice that
it would be with the passage of time, in default or violation of any term,
condition or provision of (i) its charter documents or bylaws; (ii) any
judgment, decree or order applicable to it; or (iii) any loan or credit
agreement, note, bond, mortgage, indenture, material contract, agreement,
lease, license or other instrument to which US Co or any US Co Subsidiary is
now a party or by which it or any of its properties or assets may be bound,
except in the case of item (iii) for defaults and violations which,
individually or in the aggregate, would not have a Material Adverse Effect on
US Co.
3.9      LITIGATION; INVESTIGATIONS
         There is no claim, action, suit or proceeding pending or, to the
knowledge of US Co, threatened, which would, if adversely determined,
individually or in the aggregate, have a Material Adverse Effect on US Co, nor
is there any judgment, decree, injunction, rule or order of any Governmental
Entity or arbitrator outstanding against US Co or any of the US Co Subsidiaries
having, or which, insofar as reasonably can be foreseen, in the future could
have, any such effect. There is no investigation pending or, to the knowledge
of US Co, threatened, against US Co or any of the US Co Subsidiaries before any
Governmental Entity which could have any such effect.

         (n) Exclusivity; Acquisition Transactions. Unless and until this
Agreement shall have been terminated by either party pursuant to Article 6
hereof, it shall not (and it shall cause its directors, representatives, agents
or affiliates (collectively "Representatives")) not to take or cause to take
(or cause any of the Chauvco Subsidiaries to take), directly or indirectly, any
of the following actions with any party other than US Co and its designees: (i)
solicit, encourage, initiate or participate in any negotiations, inquiries or
discussions with respect to any offer or proposal (x) to acquire in any manner,
directly or indirectly, all or any significant part of the business or assets
of Chauvco and the Chauvco Subsidiaries taken as a whole or (y) to acquire in
any manner, directly or indirectly, more than 25% of the voting power of the
capital shares of Chauvco, whether by arrangement, amalgamation, merger,
consolidation, other business combination, purchase of assets, tender or
exchange offer or otherwise (each of the foregoing, an "Acquisition
Transaction"), (ii) after the date hereof furnish or provide any information
with respect to, or otherwise take any action that facilitates, any inquiries
or the making of any proposal that constitutes, or may reasonably be expected
to lead to any inquiry, offer or proposal for, an Acquisition Transaction
except in the ordinary course of business (and unrelated to an Acquisition
Transaction) and as required by law or pursuant to a governmental request for
information, (iii) enter into or execute any agreement or arrangement relating
to an Acquisition Transaction, plan of reorganization, or other agreement
calling for the sale of all or any significant part of its business and
properties or the acquisition in any manner of more than 25% of the voting
power of the capital shares of Chauvco; or (iv), except as required by law,
make or authorize any public statement, recommendation or solicitation with
respect to any Acquisition Transaction or any offer or proposal relating to an
Acquisition Transaction other than with respect to the Arrangement (provided
that neither the Board of Directors of Chauvco nor any committee thereof shall
(x) withdraw or modify, or propose to withdraw or modify, in a manner adverse
to US Co, the approval and recommendation by such Board of Directors or such
committee of this Agreement, the Plan of Arrangement or the Arrangement or (y)
approve or recommend, or propose to approve or recommend, any Acquisition
Transaction, except with respect to either clause (x) or (y) in the case of a
Superior Transaction (as hereinafter defined) and then only at or after the
termination of this Agreement pursuant to Section 6.1(g)); and
         (o) Alternative Transaction. Notwithstanding the foregoing, prior to
the approval of this Agreement and the Arrangement by the holders of Chauvco
Common Shares at the Chauvco Meeting, nothing contained in this Agreement shall
prevent the Board of Directors of Chauvco (or its Representatives pursuant to
its instructions) from: (i) engaging in discussions or negotiations with (but
not soliciting or initiating such discussions or negotiations or encouraging
inquiries from) a party concerning an unsolicited Acquisition Transaction; or
(ii) providing non-public information in connection with an unsolicited
Acquisition Transaction with respect to Chauvco or the Chauvco Subsidiaries
that has previously been provided to US Co pursuant to a customary
confidentiality agreement (having terms substantially similar to the
Confidentiality Agreement (as hereinafter defined)), in each case if the
Chauvco Board of Directors first determines in good faith, based on the advice
of outside legal counsel, that such action is required by reason of the
fiduciary duties of the members of the Board of Directors of Chauvco to Chauvco
or to Chauvco's shareholders under applicable law and that such unsolicited
Acquisition Transaction involves consideration to the shareholders of Chauvco
with a value that the Board of Directors of Chauvco in good faith believe,
after receiving advice from Chauvco's financial advisors, is superior to the
consideration to the shareholders provided for in the Arrangement; provided
that in each such event, Chauvco first notifies US Co of such determination by
the Chauvco Board of Directors and further notifies US Co of the fact that it
is furnishing information to or entering into discussions or negotiations with
a
   30
                                     - 30 -
person or entity and Chauvco keeps US Co informed of the status (including all
terms and conditions thereof but not the identity of such person or entity) of
any such discussions or negotiations. Except to the extent expressly referenced
in this Section, nothing in this Section, however, shall relieve Chauvco from
complying with the other terms of this Agreement. If Chauvco or any Chauvco
Subsidiary receives any unsolicited offer or proposal to enter negotiations
relating to an Acquisition Transaction, Chauvco shall immediately notify US Co
thereof. On the date hereof, Chauvco shall immediately cease and cause to be
terminated any existing solicitation, initiation, encouragement, activity,
discussion or negotiation with any parties conducted heretofore by Chauvco or
any Representatives with respect to any Acquisition Transaction and, in
connection therewith, Chauvco shall exercise all rights to require the return
of information regarding Chauvco previously provided to such parties. In no
event may the Board of Directors of Chauvco or any committee thereof (x)
withdraw or modify, or propose to withdraw or modify, in a manner adverse to US
Co, the approval and recommendation by such Board of Directors or such
committee of this Agreement, the Plan of Arrangement or the Arrangement or (y)
approve or recommend, or propose to approve or recommend, any Acquisition
Transaction, except with respect to either clause (x) or (y) in the case of a
Superior Proposal and then only at or after the termination of this Agreement
pursuant to Section 6.1(g). As used in this Agreement, a "Superior Proposal"
means (x) a bona fide written offer for an Acquisition Transaction to acquire,
directly or indirectly, for consideration consisting of cash and/or securities,
more than 50% of the shares and/or voting power of the capital shares of
Chauvco then outstanding or all or substantially all the assets of Chauvco, and
(y) otherwise on terms which the Board of Directors of Chauvco determines in
its good faith judgment to be more favorable to Chauvco than the Arrangement
(based on the written opinion, with only customary qualifications, of Chauvco's
independent financial advisor that the value of the consideration provided for
in such proposal is superior to the value of the consideration provided for in
the Arrangement), for which financing, to the extent required, is then
committed or which, in the good faith judgment of the Board of Directors of
Chauvco, based on advice from Chauvco's independent financial advisor, is
reasonably capable of being financed by such third party and for which the
Board of Directors of Chauvco determines, in its good faith judgment, that such
proposed transaction is reasonably likely to be consummated without undue
delay;
         (p) Chauvco Options.  Ensure that the consent of the Optionholders as a
class is either obtained or not required;
         (q) Chauvco Affiliates.  On or prior to the Effective Time, cause its 
Affiliates (as such term is defined in the Exchange Act) to execute and deliver 
customary letters in connection with Rule 145 of the Securities Act;
         (r) Shareholders Rights Plan. Take such action as may be necessary so
that the Chauvco SRP shall be waived immediately prior to the Effective Time
and not apply to the transactions contemplated herein. Chauvco shall utilize
its best efforts to keep the Chauvco SRP in full force and effect unamended
until such waiver; and
         (s) International Contracts. Not enter into any binding contracts with
any party in any country upon which the U.S. Government has imposed
international economic sanctions with respect to U.S. persons doing business.

the character of its business provided nothing herein shall prevent the

contemporaneously with such termination tendered payment to US Co, or its

                                     - 39 -

                           forth in Exhibit E hereto.
7.4      INDEMNIFICATION AND RELATED MATTERS
         (a) US Co agrees that all rights to indemnification existing in favor
of the present or former directors and officers of Chauvco (as such) or any of
the Chauvco Subsidiaries or present or former directors and officers (as such)
of Chauvco or any of the Chauvco Subsidiaries serving or who served at
Chauvco's or any of the Chauvco Subsidiaries' request as a director or officer
of another corporation, partnership, joint venture, trust, employee benefit
plan or other enterprise, as provided in Chauvco's charter or bylaws or similar
documents of any of the Chauvco Subsidiaries in effect as of the date hereof
with respect to matters occurring prior to the Effective Time, shall survive
and shall continue in full force and effect and without modification for a
period of not less than the statutes of limitations applicable to such matters.
         (b) From and after the Effective Time, US Co shall and shall cause
Chauvco to indemnify and hold harmless to the fullest extent permitted under
the ABCA, each director and officer of US Co Sub, Chauvco or any Chauvco
Subsidiary including, without limitation, officers and directors, serving on or
prior to the date hereof against any costs and expenses (including reasonable
attorney's fees on a solicitor and his own client basis), judgments, fines,
losses, claims and damages and liabilities, and amounts paid in settlement
thereof with the consent of the indemnifying party, in connection with any
claim, action, suit, proceeding or investigation relating to any of the
transactions contemplated hereby or the Arrangement. In the event of any such
claim, action, suit, proceeding or investigation, US Co shall cause Chauvco to
pay the reasonable fees and expenses of counsel in advance of the final
disposition of any such claim, action, suit, proceeding or investigation to the
fullest extent permitted by law subject to the limitations imposed by the ABCA.
Without limiting the foregoing, in the event any such claim, action, suit,
proceeding or investigation is brought against any indemnified parties, (i) the
indemnified parties may retain counsel reasonably satisfactory to US Co and,
subject to limitations imposed by the ABCA, Chauvco shall (or US Co shall cause
Chauvco to) pay all reasonable fees and expenses of such counsel for the
indemnified parties promptly as statements therefor are received; and (ii) US
Co will use all reasonable efforts to assist in the defense
   40
                                     - 40 -
of such matter; provided, however, that neither Chauvco nor US Co shall be
liable for any settlement effected without its prior written consent. Any
indemnified party wishing to claim indemnification under this section, upon
learning of any such claim, action, suit, proceeding or investigation, shall
notify US Co (but the failure to so notify shall not relieve a party from any
liability which it may have under this section except to the extent such
failure prejudices such party). The indemnified parties as a group may retain
only one law firm in any jurisdiction to represent them with respect to each
such matter unless such counsel determines that there is, under applicable
standards of professional conduct, a conflict on any significant issue between
the positions of any two or more indemnified parties, in which event such
additional counsel may be required to be retained by the indemnified parties.
         (c) Subject to limitations imposed by the ABCA, Chauvco shall (or US
Co shall cause Chauvco to) pay all expenses, including attorney's fees on a
solicitor and his own client basis, as the same may be incurred by any
indemnified parties in any action by any indemnified party or parties seeking
to enforce the indemnity or other obligations provided for in this section;
provided, however, that Chauvco will be entitled to reimbursement for any
advances made under this section to any indemnified party who ultimately proves
unsuccessful in enforcing the indemnity as finally determined by a
non-appealable judgment in a court of competent jurisdiction, and payment of
such expenses in advance of the final disposition of the action shall be made
only upon receipt of any undertaking by the indemnified party to reimburse all
amounts advanced if such action ultimately proves unsuccessful.
         (d) There shall be maintained in effect for not less than six years
from the Effective Time the current policies of the directors' and officers'
liability insurance maintained by Chauvco in the amounts and with the coverages
in effect on the date of this Agreement. US Co may, however, substitute
therefor policies of at least the same coverage containing terms and conditions
which are no less advantageous, provided that such substitution shall not
result in any gaps or lapses in coverages with respect to matters occurring
prior to the Effective Time.
         (e) This section, which shall survive the consummation of this
Agreement and the Arrangement, is intended to benefit each person or entity
indemnified hereunder.
7.5      LOCK-UP AGREEMENTS
         Concurrently with the execution of this Agreement, Chauvco shall cause
those shareholders of Chauvco listed in Exhibit E hereto and US Co shall cause
those shareholders of US Co listed in Exhibit E hereto to execute and deliver
to the other lock-up agreements in such forms as may be mutually agreed by the
parties, acting reasonably.
7.6      EMPLOYEE MATTERS
         Subject to applicable law, US Co, the US Co Subsidiaries, and the
employee benefit plans and programs ("US Co Benefit Plans") of US Co shall
recognize the number of years of service currently recognized by Chauvco of
each individual employed by Chauvco or a Chauvco Subsidiary immediately prior
to the Effective Date, provided nothing in this provision shall require US Co
to amend any of the US Co Benefit Plans where such amendment would require
regulatory filings or approvals.

operations, debts or liabilities of CR and Chauvco which are being purchased by
CRI and with respect to the transactions contemplated in this Section 7.7
(provided that with respect to tax matters, the extent of the indemnity shall
be limited to that set out in (i)); (iv) provide that CR and Chauvco will
assume and be responsible for and will indemnify, defend and hold CRI harmless
from and against any liabilities CRI may be or become subject to which relate

which are not being purchased by CRI; (v) provide that Chauvco, subject to
confidentiality provisions, will retain copies of the books and records of such
companies; and (vi) provide that the Chauvco name shall not be used in

         (g) CRI shall on or prior to the Effective Date, be provided with
copies of all confidentiality agreements entered into by Chauvco in connection
with the strategic alternatives review process of Chauvco; and
         (h) the representations and warranties of Chauvco contained in this
Agreement shall be read as if the transactions in this Section 7.7 shall have

                           the Shares and Options set forth on Schedule A hereto
                           constitute all of the issued and outstanding Shares

                           the Shareholder. Except as otherwise set forth in
                           Schedule A, the Shareholder has sole power of
                           disposition, sole power of conversion, sole power to

                           each case with respect to all of the Shares and
                           Options attributable to the Shareholder set forth on
                           Schedule A hereto, with no material limitations,
                           qualifications or restrictions on such rights,
                           subject to applicable securities laws and the terms

                           this Agreement. This Agreement has been duly and
                           validly executed and delivered by the Shareholder and
                           constitutes a valid and binding agreement of the

                           trustee whose consent is required for the execution
                           and delivery of this Agreement or the consummation by
                           the Shareholder of the transactions contemplated

                           Options constitute community property, this Agreement
                           has been duly authorized, executed and delivered by,

                           extent that any conflict, breach, default or
                           violation would not interfere with the ability of the
                           Shareholder to perform the obligations hereunder.
                  (iv)     No Encumbrances. Except as required by Section 2, at

                           liens, claims, security interests, proxies, voting
                           trusts or agreement, understandings or arrangements

                           arrangements that do not limit or impair the
                           Shareholder's ability to perform his obligations
                           under this Agreement.

                           reasonably be expected to have effect of preventing

                           Shareholder's obligations under this Agreement,
                           provided however that the Shareholder shall be

                           reasonable request and without further
                           consideration, the Shareholder shall execute and
                           deliver such additional documents as may be
                           necessary or desirable to consummate and make
                           effective, in the most expeditious manner

         (d)      Severability. Whenever possible, each provision or portion of
                  any provision of this Agreement will be interpreted in such
                  manner as to be effective and valid under applicable law but
                  if any provision or portion of any provision of this
                  Agreement is held to be invalid, illegal or unenforceable in
                  any respect under any applicable law or rule in any
                  jurisdiction, such invalidity, illegality or unenforceability
                  will not affect any other provision or portion of any
                  provision in such jurisdiction, and this Agreement will be
                  reformed, construed and enforced in such jurisdiction as if
                  such invalid, illegal or unenforceable provision or portion
                  of any provision had never been contained herein.
         (e)      Specific Performance. Each of the parties hereto recognizes
                  and acknowledges that a breach by the Shareholder of any
                  covenants or agreements contained in this Agreement will
                  cause US Co to sustain damages for which it would not have an
                  adequate remedy at law for money damages, and therefore each
                  of the parties hereto agrees that in the event of any such
                  breach US Co shall be entitled to the remedy of specific
                  performance of such covenants and agreements and injunctive
                  and other equitable relief in addition to any other remedy to
                  which it may be entitled, at law or in equity.
         (f)      Remedies Cumulative. All rights, powers and remedies provided
                  under this Agreement or otherwise available in respect hereof
                  at law or in equity shall be cumulative and not alternative,
                  and the exercise of any thereof by any party shall not
                  preclude the simultaneous or later exercise of any other such
                  right, power or remedy by such party.
         (g)      No Waiver. The failure of any party hereto to exercise any
                  right, power or remedy provided under this Agreement or
                  otherwise available in respect hereof at law or in equity, or
                  to insist upon compliance by any other party hereto with its
                  obligations hereunder, and any custom or practice of the
                  parties at variance with the terms hereof, shall not
                  constitute a waiver by such party of its right to exercise
                  any such or other right, power or remedy or to demand such
                  compliance.
         (h)      No Third Party Beneficiaries. This Agreement is not intended
                  to be for the benefit of, and shall not be enforceable by,
                  any person or entity who or which is not a party hereto;
                  provided that, in the event of the Shareholder's death, the
                  benefits and obligations of such Shareholder hereunder shall
                  inure to his successors and heirs.
         (i)      Governing Law. This Agreement shall be governed and construed
                  in accordance with the laws of Alberta.
         (j)      Jurisdiction. Each party hereby irrevocably submits to the
                  exclusive jurisdiction of Alberta in any action, suit or
                  proceeding arising in connection with this Agreement, and
                  agrees that any such action, suit or proceeding shall be
                  brought only in such court (and waives any objection based on
                  forum non conveniens or any other objection to venue
                  therein); provided, however, that such consent to
                  jurisdiction is solely for the purpose referred to in this
                  paragraph and shall not be deemed to be a general submission
                  to the jurisdiction of Alberta other than for such purposes.

         (l)      Counterparts. This Agreement may be executed in counterparts,
                  each of which shall be deemed to be an original, but all of
                  which, taken together, shall constitute one and the same
                  Agreement. This Agreement shall not be effective as to any
                  party hereto until such time as this Agreement or a
                  counterpart thereof has been executed and delivered by each
                  party hereto.
7.       TERMINATION
         This Agreement shall terminate without any further action on the part
of any party hereto upon the earlier to occur of the Effective Time or the

for any breaches of the Agreement that occurred prior to such termination.

executed effective the 3rd day of September, 1997.

         Preferred Voting Stock"), upon the terms and conditions set forth in
         Exhibit D to the Combination Agreement, in substantially the form
         presented to and reviewed by each member of the Board, and hereby

Voting Stock shall be amended, except upon the approval of the holder of the
outstanding share of Special Preferred Voting Stock. At such time as no
Exchangeable Shares shall be outstanding, the Special Preferred Voting Stock
shall automatically be redeemed, with the $1.00 liquidation preference due and
payable upon such redemption.

Voting Stock is outstanding, the Company shall (i) fully comply with all terms
of the Exchangeable Shares and with all contractual obligations of the Company
associated with such Exchangeable Shares and (ii) not amend, alter, change or
repeal this Section 2 except upon the unanimous approval of the holder of the

(q) the terms, if any, of the transfer, mortgage, pledge or assignment as security for the Debt Securities of the series of any properties, assets, moneys, proceeds, securities or other collateral, including whether certain provisions of the Trust Indenture Act are applicable and any corresponding changes to provisions of this Indenture as currently in effect; (r) any addition to or change in the Events of Default with respect to the Debt Securities of the series and any change in the right of the Trustee or the Holders to declare the principal of, and premium and interest on, such Debt Securities due and payable; (s) if the Debt Securities of the series shall be issued in whole or in part in the form of a Global Security or Securities, the terms and conditions, if any, upon which such Global Security or Securities may be exchanged in whole or in part for other individual Debt Securities in definitive registered form; and the Depositary for such Global Security or Securities and the form of any legend or legends to be borne by any such Global Security or Securities in addition to or in lieu of the legend referred to in Section 2.15; (t) any trustees, authenticating or paying agents, transfer agents or registrars; (u) the applicability of, and any addition to or change in the covenants and definitions currently set forth in this Indenture or in the terms currently set forth in Article X, 18 25 including conditioning any merger, conveyance, transfer or lease permitted by Article X upon the satisfaction of an Indebtedness coverage standard by the Company and Successor Company (as defined in Article X); (v) the terms, if any, of any Guarantee of the payment of principal of, and premium, if any, and interest on, Debt Securities of the series and any corresponding changes to the provisions of this Indenture as currently in effect; (w) the subordination, if any, of the Debt Securities of the series pursuant to Article XII and any changes or additions to Article XII; (x) with regard to Debt Securities of the series that do not bear interest, the dates for certain required reports to the Trustee; and (y) any other terms of the Debt Securities of the series (which terms shall not be prohibited by the provisions of this Indenture). All Debt Securities of any one series and the Coupons, if any, appertaining thereto shall be substantially identical except as to denomination and except as may otherwise be provided in or pursuant to such resolution of the Board of Directors and as set forth in such Officers' Certificate or in any such Indenture supplemental hereto. Section 2.04. EXECUTION OF DEBT SECURITIES. The Debt Securities and the Coupons, if any, shall be signed on behalf of the Company by its Chairman of the Board, its Vice Chairman, its President or a Vice President and by its Secretary, an Assistant Secretary, a Treasurer or an Assistant Treasurer. Such signatures upon the Debt Securities and Coupons may be the manual or facsimile signatures of the present or any future such authorized officers and may be imprinted or otherwise reproduced on the Debt Securities and Coupons. The seal of the Company, if any, may be in the form of a facsimile thereof and may be impressed, affixed, imprinted or otherwise reproduced on the Debt Securities and Coupons. Only such Debt Securities and Coupons as shall bear thereon a certificate of authentication substantially in the form hereinbefore recited, signed manually by the Trustee, shall be entitled to the benefits of this Indenture or be valid or obligatory for any purpose. Such certificate by the Trustee upon any Debt Security or Coupon executed by the Company shall be conclusive evidence that the Debt Security or Coupon so authenticated has been duly authenticated and delivered hereunder. In case any officer of the Company who shall have signed any of the Debt Securities or Coupons shall cease to be such officer before the Debt Securities or Coupons so signed shall have been authenticated and delivered by the Trustee, or disposed of by the Company, such Debt Securities or Coupons nevertheless may be authenticated and delivered or disposed of as though the Person who signed such Debt Securities or Coupons had not ceased to be such officer of the Company; and any Debt Security or Coupon may be signed on behalf of the Company by such Persons as, at the actual date of the execution of such Debt Security or Coupon, shall be the proper 19 26 officers of the Company, although at the date of such Debt Security or Coupon or of the execution of this Indenture any such Person was not such officer. Section 2.05. AUTHENTICATION AND DELIVERY OF DEBT SECURITIES. At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Debt Securities, with appropriate Coupons, if any, of any series executed by the Company to the Trustee for authentication, and the Trustee shall thereupon authenticate and deliver said Debt Securities and Coupons to or upon a Company Order. In authenticating such Debt Securities and Coupons, and accepting the additional responsibilities under this Indenture in relation to such Debt Securities and Coupons, the Trustee shall be entitled to receive, and (subject to Section 7.01) shall be fully protected in relying upon: (a) a copy of any resolution or resolutions of the Board of Directors, certified by the Secretary or Assistant Secretary of the Company, authorizing the terms of issuance of any series of Debt Securities and Coupons; (b) an executed supplemental Indenture, if any; (c) an Officers' Certificate; and (d) an Opinion of Counsel prepared in accordance with Section 13.05 which shall also state: (i) that the form of such Debt Securities and Coupons has been established by or pursuant to a resolution of the Board of Directors or by a supplemental Indenture as permitted by Section 2.01 in conformity with the provisions of this Indenture; (ii) that the terms of such Debt Securities and Coupons have been established by or pursuant to a resolution of the Board of Directors or by a supplemental Indenture as permitted by Section 2.03 in conformity with the provisions of this Indenture; (iii) that such Debt Securities and Coupons, when authenticated and delivered by the Trustee and issued by the Company in the manner and subject to any conditions specified in such Opinion of Counsel, will constitute valid and legally binding obligations of the Company, enforceable in accordance with their terms except as (A) the enforceability thereof may be limited by bankruptcy, insolvency or similar laws affecting the enforcement of creditors' rights generally and (B) rights of acceleration and the availability of equitable remedies may be limited by equitable principles of general applicability; (iv) that the Company has the corporate power to issue such Debt Securities and Coupons and has duly taken all necessary corporate action with respect to such issuance; (v) that the issuance of such Debt Securities and Coupons will not contravene the charter or by-laws of the Company or result in any material violation of any 20 27 of the terms or provisions of any law or regulation or of any indenture, mortgage or other agreement known to such counsel by which the Company is bound; (vi) that authentication and delivery of such Debt Securities and Coupons and the execution and delivery of any supplemental Indenture will not violate the terms of this Indenture; and (vii) such other matters as the Trustee may reasonably request. Such Opinion of Counsel need express no opinion as to whether a court in the United States would render a money judgment in a currency other than that of the United States. The Trustee shall have the right to decline to authenticate and deliver any Debt Securities or Coupons under this Section 2.05 if the Trustee, being advised by counsel, determines that such action may not lawfully be taken or if the Trustee in good faith by its board of directors or trustees, executive committee or a trust committee of directors, trustees or vice presidents shall determine that such action would expose the Trustee to personal liability to existing Holders. The Trustee may appoint an authenticating agent reasonably acceptable to the Company to authenticate Debt Securities and Coupons, if any, of any series. Unless limited by the terms of such appointment, an authenticating agent may authenticate Debt Securities whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as any Registrar, paying agent or agent for service of notices and demands. Unless otherwise provided in the form of Debt Security for any series, each Debt Security shall be dated the date of its authentication. Section 2.06. DENOMINATION OF DEBT SECURITIES. Unless otherwise provided in the form of Debt Security for any series, the Debt Securities of each series shall be issuable only as Registered Securities in such denominations as shall be specified or contemplated by Section 2.03. In the absence of any such specification with respect to the Debt Securities of any series, the Debt Securities of such series shall be issuable in denominations of $1,000 and any integral multiple thereof. Section 2.07. REGISTRATION OF TRANSFER AND EXCHANGE. (a) The Company shall keep or cause to be kept a register for each series of Registered Securities issued hereunder (hereinafter collectively referred to as the "Debt Security Register"), in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Registered Securities and the transfer of Registered Securities as in this Article II provided. At all reasonable times the Debt Security Register shall be open for inspection by the Trustee. Subject to Section 2.15, upon due presentment for registration of transfer of any Registered Security at any office or agency to be maintained by the Company in accordance with the provisions of Section 4.02, the Company shall execute and the Trustee shall authenticate and deliver in the name of the transferee or transferees a new Registered Security or Registered Securities of authorized denominations for a like 21 28 aggregate principal amount. In no event may Registered Securities, including Registered Securities received in exchange for Bearer Securities, be exchanged for Bearer Securities. Unless and until otherwise determined by the Company by resolution of the Board of Directors, the register of the Company for the purpose of registration, exchange or registration of transfer of the Registered Securities shall be kept at the corporate trust office of the Trustee and, for this purpose, the Trustee shall be designated "Registrar". Registered Securities of any series (other than a Global Security, except as set forth below) may be exchanged for a like aggregate principal amount of Registered Securities of the same series of other authorized denominations. Subject to Section 2.15, Registered Securities to be exchanged shall be surrendered at the office or agency to be maintained by the Company as provided in Section 4.02, and the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor the Registered Security or Registered Securities which the Holder making the exchange shall be entitled to receive. At the option of the Holder of Bearer Securities of any series, except as otherwise specified as contemplated by Section 2.03(8) or 2.03(19) with respect to a Global Security representing Bearer Securities, Bearer Securities of such series may be exchanged for Registered Securities (if the Debt Securities of such series are issuable as Registered Securities) or Bearer Securities of the same series, of any authorized denomination or denominations, of like tenor and aggregate principal amount, upon surrender of the Bearer Securities to be exchanged at the office or agency of the Company maintained for such purpose, with all unmatured Coupons and all matured Coupons in Default thereto appertaining; provided, however, that delivery of a Bearer Security shall occur only outside the United States. If such Holder is unable to produce any such unmatured Coupon or Coupons or matured Coupon or Coupons in Default, such exchange may be effected if such Holder's Bearer Securities are accompanied by payment in funds acceptable to the Company and the Trustee in an amount equal to the face amount of such missing Coupon or Coupons, or the surrender of such missing Coupon or Coupons may be waived by the Company and the Trustee if there be furnished to them such security or indemnity as they may require to save each of them and any paying agent harmless. If thereafter such Holder shall surrender to any paying agent any such missing Coupon in respect of which such a payment shall have been made, such Holder shall be entitled to receive the amount of such payment; provided, however, that, except as otherwise provided in Section 2.12, interest represented by Coupons shall be payable only upon presentation and surrender of those Cou pons at an office or agency located outside the United States. Whenever any Debt Securities are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Debt Securities that the Holder making the exchange is entitled to receive. Notwithstanding the foregoing, the exchange of Bearer Securities for Registered Securities will be subject to the provisions of United States income tax laws and regulations applicable to Debt Securities in effect at the time of such exchange. 22 29 (b) All Registered Securities presented or surrendered for registration of transfer, exchange or payment shall (if so required by the Company, the Trustee or the Registrar) be duly endorsed or be accompanied by a written instrument or instruments of transfer, in form satisfactory to the Company, the Trustee and the Registrar, duly executed by the Registered Holder or his attorney duly authorized in writing. All Debt Securities issued in exchange for or upon transfer of Debt Securities shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture as the Debt Securities surrendered for such exchange or transfer. No service charge shall be made for any exchange or registration of transfer of Debt Securities (except as provided by Section 2.09), but the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto, other than those expressly provided in this Indenture to be made at the Company's own expense or without expense or without charge to the Holders. The Company shall not be required (i) to issue, register the transfer of or exchange any Debt Securities for a period of 15 days next preceding any mailing of notice of redemption of Debt Securities of such series or (ii) to register the transfer of or exchange any Debt Securities selected, called or being called for redemption; provided, however, that, if specified pursuant to Section 2.03, any Bearer Securities of any series that are exchangeable for Registered Securities and that are called for redemption pursuant to Section 3.02 may, to the extent permitted by applicable law, be exchanged for one or more Registered Securities of such series during the period preceding the redemption date therefor. Prior to the due presentation for registration of transfer of any Debt Security, the Company, the Trustee, any paying agent or any Registrar may deem and treat the Person in whose name a Debt Security is registered as the absolute owner of such Debt Security for the purpose of receiving payment of principal of, and premium, if any, and interest on, such Debt Security and for all other purposes whatsoever, whether or not such Debt Security is overdue, and none of the Company, the Trustee, any paying agent or Registrar shall be affected by notice to the contrary. None of the Company, the Trustee, any agent of the Trustee, any paying agent or any Registrar will have any responsibility or liability for any aspect of the records relating to, or payments made on account of, beneficial ownership interests of a Global Security or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests. Section 2.08. TEMPORARY DEBT SECURITIES. Pending the preparation of definitive Debt Securities of any series, the Company may execute and the Trustee shall authenticate and deliver temporary Debt Securities (printed, lithographed, photocopied, typewritten or otherwise produced) of any authorized denomination, and substantially in the form of the definitive Debt Securities in lieu of which they are issued, in registered form or, if authorized, in bearer form with one or more Coupons or without Coupons, and with such omissions, insertions and variations as may be appropriate for temporary Debt Securities and Coupons, all as may be determined by the Company with the concurrence of the Trustee. Temporary Debt Securities and Coupons may contain such 23 30 reference to any provisions of this Indenture as may be appropriate. Every temporary Debt Security shall be executed by the Company and be authenticated by the Trustee upon the same conditions and in substantially the same manner, and with like effect, as the definitive Debt Securities. If temporary Debt Securities of any series are issued, the Company will cause definitive Debt Securities of such series to be prepared without unreasonable delay. Except as otherwise specified as contemplated by Section 2.03(8)(z) with respect to a series of Debt Securities issuable as Bearer Securities or as one or more Global Securities representing individual Bearer Securities of the series, (a) after the preparation of definitive Debt Securities of such series, the temporary Debt Securities of such series shall be exchangeable for definitive Debt Securities of such series upon surrender of the temporary Debt Securities of such series at the office or agency of the Company at a Place of Payment for such series, without charge to the Holder thereof, except as provided in Section 2.07 in connection with a transfer and except that a Person receiving definitive Bearer Securities shall bear the cost of insurance, postage, transportation and the like unless otherwise specified pursuant to Section 2.03, and (b) upon surrender for cancelation of any one or more temporary Debt Securities of any series (accompanied by any unmatured Coupons appertaining thereto), the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a like principal amount of definitive Debt Securities of the same series of authorized denominations and of like tenor; provided, however, that no definitive Bearer Security shall be delivered in exchange for a temporary Registered Security; and provided, further, however, that delivery of a Global Security representing individual Bearer Securities or a Bearer Security shall occur only outside the United States. Until so exchanged, temporary Debt Securities of any series shall in all respects be entitled to the same benefits under this Indenture as definitive Debt Securities of such series, except as otherwise specified as contemplated by Section 2.03(8)(y) with respect to the payment of interest on Global Securities in temporary form. Unless otherwise specified pursuant to Section 2.03, the Company will execute and deliver each definitive Global Security representing individual Bearer Securities and each Bearer Security to the Trustee at its principal office in London or such other place outside the United States specified pursuant to Section 2.03. Upon any exchange of a portion of a temporary Global Security for a definitive Global Security or for the individual Debt Securities represented thereby pursuant to Section 2.07 or this Section 2.08, the temporary Global Security shall be endorsed by the Trustee to reflect the reduction of the principal amount evidenced thereby, whereupon the principal amount of such temporary Global Security shall be reduced for all purposes by the amount to be exchanged and endorsed. Section 2.09. MUTILATED, DESTROYED, LOST OR STOLEN DEBT SECURITIES. If (a) any mutilated Debt Security or any mutilated Coupon with the Coupon Security to which it appertains (and all unmatured Coupons attached thereto) is surrendered to the Trustee at its corporate trust office (in the case of Registered Securities) or at its principal London office (in the case of Bearer Securities) or (b) the Company and the Trustee receive evidence to their satisfaction of the destruction, loss or theft of any Debt Security or any Coupon, and there is delivered to the Company and the Trustee such security or indemnity as may be required by them to save each of them and any paying agent harmless, and neither the Company nor the Trustee receives notice that such Debt Security or 24 31 Coupon has been acquired by a bona fide purchaser, then the Company shall execute and, upon a Company Order, the Trustee shall authenticate and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or stolen Debt Security or in exchange for the Coupon Security to which such mutilated, destroyed, lost or stolen Coupon appertained, a new Debt Security of the same series of like tenor, form, terms and principal amount, bearing a number not contemporaneously Outstanding, and, in the case of a Coupon Security, with such Coupons attached thereto that neither gain nor loss in interest shall result from such exchange or substitution. Upon the issuance of any substituted Debt Security, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses connected therewith. In case any Debt Security or Coupon which has matured or is about to mature or which has been called for redemption shall become mutilated or be destroyed, lost or stolen, the Company may, instead of issuing a substituted Debt Security or Coupon, pay or authorize the payment of the same (without surrender thereof except in the case of a mutilated Debt Security or Coupon) if the applicant for such payment shall furnish the Company and the Trustee with such security or indemnity as either may require to save it harmless from all risk, however remote, and, in case of destruction, loss or theft, evidence to the satisfaction of the Company and the Trustee of the destruction, loss or theft of such Debt Security or Coupon and of the ownership thereof; provided, however, that payment of principal of, and premium, if any, and interest on, Bearer Securities or Coupons shall, except as otherwise provided in Section 2.12, be payable only at an office or agency located outside the United States. Every substituted Debt Security of any series, with its Coupons, if any, issued pursuant to the provisions of this Section 2.09 by virtue of the fact that any Debt Security or Coupon is destroyed, lost or stolen shall constitute an original additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Debt Security or Coupon shall be found at any time, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Debt Securities of that series and Coupons, if any, duly issued hereunder. All Debt Securities and Coupons, if any, shall be held and owned upon the express condition that the foregoing provisions are exclusive with respect to the replacement or payment of mutilated, destroyed, lost or stolen Debt Securities or Coupons, and shall preclude any and all other rights or remedies, notwithstanding any law or statute existing or hereafter enacted to the contrary with respect to the replacement or payment of negotiable instruments or other securities without their surrender. Section 2.10. CANCELATION OF SURRENDERED DEBT SECURITIES. All Debt Securities surrendered for payment, redemption, registration of transfer or exchange and all Coupons surrendered for payment or exchange shall, if surrendered to the Company or any paying agent or a Registrar, be delivered to the Trustee for cancelation by it, or if surrendered to the Trustee, shall be canceled by it, and no Debt Securities or Coupons shall be issued in lieu thereof except as expressly permitted by any of the provisions of this Indenture. All canceled Debt Securities and Coupons held by the Trustee shall be destroyed (subject to the record retention requirements of the Exchange Act) and certification of their destruction delivered to the Company, unless otherwise directed. On request of the Company, the Trustee shall deliver to the Company canceled Debt Securities and Coupons held by the Trustee. If the Company shall acquire any of the Debt Securities or Coupons, however, such acquisition shall not operate as a redemption or satisfaction of the indebtedness represented thereby unless and until the same are delivered or surrendered to the 25 32 Trustee for cancelation. The Company may not issue new Debt Securities or Coupons to replace Debt Securities or Coupons it has redeemed, paid or delivered to the Trustee for cancelation. Section 2.11. PROVISIONS OF THE INDENTURE AND DEBT SECURITIES FOR THE SOLE BENEFIT OF THE PARTIES AND THE HOLDERS. Nothing in this Indenture or in the Debt Securities or Coupons, expressed or implied, shall give or be construed to give to any Person, other than the parties hereto, the Holders or any Registrar or paying agent, any legal or equitable right, remedy or claim under or in respect of this Indenture, or under any covenant, condition or provision herein contained; all its covenants, conditions and provisions being for the sole benefit of the parties hereto, the Holders and any Registrar and paying agents. Section 2.12. PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED. (a) Interest on any Registered Security that is payable and is punctually paid or duly provided for on any interest payment date shall be paid to the Person in whose name such Registered Security is registered at the close of business on the regular record date for such interest notwithstanding the cancelation of such Registered Security upon any transfer or exchange subsequent to the regular record date. In case a Coupon Security of any series is surrendered in exchange for a Registered Security of such series after the close of business (at an office or agency in a Place of Payment for such series) on any regular record date and before the opening of business (at such office or agency) on the next succeeding interest payment date, such Coupon Security shall be surrendered without the Coupon relating to such interest payment date and interest will not be payable on such interest payment date in respect of the Registered Security issued in exchange for such Coupon Security, but will be payable only to the Holder of such Coupon when due in accordance with the provisions of this Indenture. Payment of interest on Registered Securities shall be made at the corporate trust office of the Trustee (except as otherwise specified pursuant to Section 2.03), or at the option of the Company, by check mailed to the address of the Person entitled thereto as such address shall appear in the Debt Security Register or, if provided pursuant to Section 2.03 and in accordance with arrangements satisfactory to the Trustee, at the option of the Registered Holder by wire transfer to an account designated by the Registered Holder. (b) No interest shall be payable with respect to a Bearer Security or Coupon unless such certification requirements as are specified pursuant to Section 2.03(8)(z) are satisfied with respect to such Bearer Security or Coupon. Interest on any Coupon Security that is payable and is punctually paid or duly provided for on any interest payment date shall be paid to the Holder of the Coupon that has matured on such interest payment date upon surrender of such Coupon on such interest payment date at the principal London office of the Trustee or at such other Place of Payment outside the United States specified pursuant to Section 2.03. Interest on any Bearer Security (other than a Coupon Security) that is payable and is punctually paid or duly provided for on any interest payment date shall be paid to the Holder of the Bearer Security upon presentation of such Bearer Security and notation thereon on such interest payment date at the principal London office of the Trustee or at such other Place of Payment outside the United States specified pursuant to Section 2.03. 26 33 Unless otherwise specified pursuant to Section 2.03, at the direction of the Holder of any Bearer Security or Coupon payable in Dollars, and subject to applicable laws and regulations, payments in respect of such Bearer Security or Coupon will be made by check drawn on a bank in New York, New York, or, in accordance with arrangements satisfactory to the Trustee, by wire transfer to a Dollar account maintained by such Holder with a bank outside the United States. If such payment at the offices of all paying agents outside the United States becomes illegal or is effectively precluded because of the imposition of exchange controls or similar restrictions on the full payment or receipt of such amounts in Dollars, then, to the extent permitted by United States tax law, the Company will appoint an office or agent in the United States at which such payment may be made. Unless otherwise specified pursuant to Section 2.03, at the direction of the Holder of any Bearer Security or Coupon payable in a Foreign Currency, payment on such Bearer Security or Coupon will be made by a check drawn on a bank outside the United States or, in accordance with arrangements satisfactory to the Trustee, by wire transfer to an appropriate account maintained by such Holder outside the United States. Except as provided in this paragraph, no payment on any Bearer Security or Coupon will be made by mail to an address in the United States or by transfer to an account in the United States. (c) Subject to the foregoing provisions of this Section 2.12 and Section 2.17, each Debt Security of a particular series delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Debt Security of the same series shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Debt Security. Section 2.13. SECURITIES DENOMINATED IN FOREIGN CURRENCIES. (a) Except as otherwise specified pursuant to Section 2.03 for Bearer Securities of any series, payment of the principal of, and premium, if any, and interest on, Bearer Securities of such series denominated in any Currency will be made in such Currency. (b) Except as otherwise specified pursuant to Section 2.03 for Registered Securities of any series, payment of the principal of, and premium, if any, and interest on, Registered Securities of such series will be made in Dollars. (c) For the purposes of calculating the principal amount of Debt Securities of any series denominated in a Foreign Currency or in units of two or more Foreign Currencies (including European Currency Units) for any purpose under this Indenture, the principal amount of such Debt Securities at any time Outstanding shall be deemed to be the Dollar Equivalent of such principal amount as of the date of any such calculation. In the event any Foreign Currency or currencies or units of two or more Currencies in which any payment with respect to any series of Debt Securities may be made ceases to be a freely convertible Currency on United States Currency markets, for any date thereafter on which payment of principal of, or premium, if any, or interest on, the Debt Securities of a series is due, the Company shall select the Currency of payment for use on such date, all as provided in the Debt Securities of such series. In such event, the Company shall, as provided in the Debt Securities of such series, notify the Trustee of the Currency which it has selected to constitute the funds necessary to meet the Company's obligations on such payment date and of the amount of such Currency to be paid. Such 27 34 amount shall be determined as provided in the Debt Securities of such series. The payment to the Trustee with respect to such payment date shall be made by the Company solely in the Currency so selected. Section 2.14. WIRE TRANSFERS. Notwithstanding any other provision to the contrary in this Indenture, the Company may make any payment of monies required to be deposited with the Trustee on account of principal of, or premium, if any, or interest on, the Debt Securities (whether pursuant to optional or mandatory redemption payments, interest payments or otherwise) by wire transfer in immediately available funds to an account designated by the Trustee on or before the date such moneys are to be paid to the Holders of the Debt Securities in accordance with the terms hereof. Section 2.15. SECURITIES ISSUABLE IN THE FORM OF A GLOBAL SECURITY. (a) If the Company shall establish pursuant to Sections 2.01 and 2.03 that the Debt Securities of a particular series are to be issued in whole or in part in the form of one or more Global Securities, then the Company shall execute and the Trustee or its agent shall, in accordance with Section 2.05, authenticate and deliver, such Global Security or Securities, which (i) shall represent, and shall be denominated in an amount equal to the aggregate principal amount of, the Outstanding Debt Securities of such series to be represented by such Global Security or Securities, or such portion thereof as the Company shall specify in an Officer's Certificate, (ii) shall be registered in the name of the Depositary for such Global Security or Securities or its nominee, (iii) shall be delivered by the Trustee or its agent to the Depositary or pursuant to the Depositary's instruction and (iv) shall bear a legend substantially to the following effect: 'Unless and until it is exchanged in whole or in part for the individual Debt Securities represented hereby, this Global Security may not be transferred except as a whole by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary', or such other legend as may then be required by the Depositary for such Global Security or Securities. (b) Notwithstanding any other provision of this Section 2.15 or of Section 2.07 to the contrary, and subject to the provisions of paragraph (c) below, unless the terms of a Global Security expressly permit such Global Security to be exchanged in whole or in part for definitive Debt Securities in registered form, a Global Security may be transferred, in whole but not in part and in the manner provided in Section 2.07, only by the Depositary to a nominee of the Depositary for such Global Security, or by a nominee of the Depositary to the Depositary or another nominee of the Depositary, or by the Depositary or a nominee of the Depositary to a successor Depositary for such Global Security selected or approved by the Company, or to a nominee of such successor Depositary. (c) (i) If at any time the Depositary for a Global Security or Securities notifies the Company that it is unwilling or unable to continue as Depositary for such Global Security or Securities or if at any time the Depositary for the Debt Securities for such series shall no longer be eligible or in good standing under the Exchange Act or other applicable statute, rule or regulation, the Company shall appoint a successor Depositary with respect to such Global Security or Securities. If a successor Depositary for such Global Security or Securities is not appointed by the Company within 90 days after the Company receives such notice or becomes aware of such ineligibility, the Company shall execute, and the Trustee 28 35 or its agent, upon receipt of a Company Order for the authentication and delivery of such individual Debt Securities of such series in exchange for such Global Security, will authenticate and deliver, individual Debt Securities of such series of like tenor and terms in definitive form in an aggregate principal amount equal to the principal amount of the Global Security in exchange for such Global Security or Securities. (ii) The Company may at any time and in its sole discretion determine that the Debt Securities of any series or portion thereof issued or issuable in the form of one or more Global Securities shall no longer be represented by such Global Security or Securities. In such event the Company will execute, and the Trustee, upon receipt of a Company Order for the authentication and delivery of individual Debt Securities of such series in exchange in whole or in part for such Global Security, will authenticate and deliver individual Debt Securities of such series of like tenor and terms in definitive form in an aggregate principal amount equal to the principal amount of such series or portion thereof in exchange for such Global Security or Securities. (iii) If specified by the Company pursuant to Sections 2.01 and 2.03 with respect to Debt Securities issued or issuable in the form of a Global Security, the Depositary for such Global Security may surrender such Global Security in exchange in whole or in part for individual Debt Securities of such series of like tenor and terms in definitive form on such terms as are acceptable to the Company, the Trustee and such Depositary. Thereupon the Company shall execute, and the Trustee or its agent upon receipt of a Company Order for the authentication and delivery of definitive Debt Securities of such series shall authenticate and deliver, without service charge, (A) to each Person specified by such Depositary a new Debt Security or Securities of the same series of like tenor and terms and of any authorized denomination as requested by such Person in aggregate principal amount equal to and in exchange for such Person's beneficial interest in the Global Security; and (B) to such Depositary a new Global Security of like tenor and terms and in an authorized denomination equal to the difference, if any, between the principal amount of the surrendered Global Security and the aggregate principal amount of Debt Securities delivered to Holders thereof. (iv) In any exchange provided for in any of the preceding three paragraphs, the Company will execute and the Trustee or its agent will authenticate and deliver individual Debt Securities. In case a Coupon Security of any series is surrendered in exchange for a Registered Security of such series after the close of business (at an office or agency in a Place of Payment for such series) on any special record date and before the opening of business (at such office or agency) on the related proposed date of payment of Defaulted Interest, such Coupon Security shall be surrendered without the Coupon relating to such proposed date of payment and Defaulted Interest will not be payable on such proposed date of payment in respect of the Registered Security issued in exchange for such Coupon Security, but will be payable only to the Holder of such Coupon when due in accordance with the provisions of this Indenture. Upon the exchange of the entire principal amount of a Global Security for individual Debt Securities, such Global Security shall be canceled by the Trustee or its agent. Except as provided in the preceding paragraph, 29 36 Registered Securities issued in exchange for a Global Security pursuant to this Section 2.15 shall be registered in such names and in such authorized denominations as the Depositary for such Global Security, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee or the Registrar. The Trustee or the Registrar shall deliver such Registered Securities to the Persons in whose names such Registered Securities are so registered. (v) Payments in respect of the principal of and interest on any Debt Securities registered in the name of the Depositary or its nominee will be payable to the Depositary or such nominee in its capacity as the registered owner of such Global Security. The Company and the Trustee may treat the Person in whose name the Debt Securities, including the Global Security, are registered as the owner thereof for the purpose of receiving such payments and for any and all other purposes whatsoever. None of the Company, the Trustee, any Registrar, the paying agent or any agent of the Company or the Trustee will have any responsibility or liability for (A) any aspect of the records relating to or payments made on account of the beneficial ownership interests of the Global Security by the Depositary or its nominee or any of the Depositary's direct or indirect participants, or for maintaining, supervising or reviewing any records of the Depositary, its nominee or any of its direct or indirect participants relating to the beneficial ownership interests of the Global Security, (B) the payments to the beneficial owners of the Global Security of amounts paid to the Depositary or its nominee, or (C) any other matter relating to the actions and practices of the Depositary, its nominee or any of its direct or indirect participants. None of the Company, the Trustee or any such agent will be liable for any delay by the Depositary, its nominee, or any of its direct or indirect participants in identifying the beneficial owners of the Debt Securities, and the Company and the Trustee may conclusively rely on, and will be protected in relying on, instructions from the Depositary or its nominee for all purposes (including with respect to the registration and delivery, and the respective principal amounts, of the Debt Securities to be issued). The Trustee shall deliver individual Bearer Securities issued in exchange for a Global Security pursuant to this Section 2.15 to the Persons and in such authorized denominations as the Depositary for such Global Security, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee; provided, however, that individual Bearer Securities shall be delivered in exchange for a Global Security only in accordance with the procedures as may be specified pursuant to Section 2.03. Notwithstanding the foregoing, the exchange of Bearer Securities for Registered Securities will be subject to the provisions of United States income tax laws and regulations applicable to debt Securities in effect at the time of such exchange. Section 2.16. MEDIUM TERM SECURITIES. Notwithstanding any contrary provision herein, if all Debt Securities of a series are not to be originally issued at one time, it shall not be necessary for the Company to deliver to the Trustee an Officers' Certificate, resolutions of the Board of Directors, supplemental Indenture, Opinion of Counsel or written order or any other document otherwise required pursuant to Section 2.01, 2.03, 2.05 or 13.05 at or prior to the time of 30 37 authentication of each Debt Security of such series if such documents are delivered to the Trustee or its agent at or prior to the authentication upon original issuance of the first such Debt Security of such series to be issued; provided, that any subsequent request by the Company to the Trustee to authenticate Debt Securities of such series upon original issuance shall constitute a representation and warranty by the Company that, as of the date of such request, the statements made in the Officers' Certificate delivered pursuant to Section 2.05 or 13.05 shall be true and correct as if made on such date and that the Opinion of Counsel delivered at or prior to such time of authentication of an original issuance of Debt Securities shall specifically state that it shall relate to all subsequent issuances of Debt Securities of such series that are identical to the Debt Securities issued in the first issuance of Debt Securities of such series. A Company Order delivered by the Company to the Trustee in the circumstances set forth in the preceding paragraph, may provide that Debt Securities which are the subject thereof will be authenticated and delivered by the Trustee or its agent on original issue from time to time upon the telephonic or written order of Persons designated in such written order (any such telephonic instructions to be promptly confirmed in writing by such Person) and that such Persons are authorized to determine, consistent with the Officers' Certificate, supplemental Indenture or resolution of the Board of Directors relating to such written order, such terms and conditions of such Debt Securities as are specified in such Officers' Certificate, supplemental Indenture or such resolution. Section 2.17. DEFAULTED INTEREST. (a) Any interest on any Debt Security of a particular series which is payable, but is not punctually paid or duly provided for, on the dates and in the manner provided in the Debt Securities of such series and in this Indenture (herein called "Defaulted Interest") shall, if such Debt Security is a Registered Security, forthwith cease to be payable to the Registered Holder thereof on the relevant record date by virtue of having been such Registered Holder, and such Defaulted Interest may be paid by the Company, at its election in each case, as provided in clause (i) or (ii) below: (i) The Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Registered Securities of such series are registered at the close of business on a special record date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each such Registered Security of such series and the date of the proposed payment, and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as in this clause provided. Thereupon the Trustee shall fix a special record date for the payment of such Defaulted Interest which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Company of such special record date and, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the special record 31 38 date therefor to be mailed, first class postage pre-paid, to each Holder thereof at its address as it appears in the Security Register, not less than 10 days prior to such special record date. Notice of the proposed payment of such Defaulted Interest and the special record date therefor having been so mailed, such Defaulted Interest shall be paid to the Persons in whose names the Registered Securities of such series are registered at the close of business on such special record date. In case a Coupon Security of any such series is surrendered in exchange for a Registered Security of such series after the close of business (at an office or agency in a Place of Payment for such series) on any special record date and before the opening of business (at such office or agency) on the related proposed date of payment of Defaulted Interest, such Coupon Security shall be surrendered without the Coupon relating to such proposed date of payment and Defaulted Interest will not be payable on such proposed date of payment in respect of the Registered Security issued in exchange for such Coupon Security, but will be payable only to the Holder of such Coupon when due in accordance with the provisions of this Indenture. (ii) The Company may make payment of any Defaulted Interest on the Registered Securities of such series in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Registered Securities of such series may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Company to the Trustee of the proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee. (b) Any Defaulted Interest payable in respect of Bearer Securities of any series shall be payable pursuant to such procedures as may be satisfactory to the Trustee in such manner that there is no discrimination between the Holders of Registered Securities (if any) and Bearer Securities of such series, and notice of the payment date therefor shall be given by the Trustee, in the name and at the expense of the Company, in the manner provided in Section 13.03 not more than 25 days and not less than 20 days prior to the date of the proposed payment. Section 2.18. JUDGMENTS. The Company may provide pursuant to Section 2.03 for Debt Securities of any series that (a) the obligation, if any, of the Company to pay the principal of, and premium, if any, and interest on, the Debt Securities of any series in a Foreign Currency or Dollars (the "Designated Currency") as may be specified pursuant to Section 2.03 is of the essence and agrees that, to the fullest extent possible under applicable law, judgments in respect of Debt Securities of such series shall be given in the Designated Currency; (b) the obligation of the Company to make payments in the Designated Currency of the principal of, and premium, if any, and interest on, such Debt Securities shall, notwithstanding any payment in any other Currency (whether pursuant to a judgment or otherwise), be discharged only to the extent of the amount in the Designated Currency that the Holder receiving such payment may, in accordance with normal banking procedures, purchase with the sum paid in such other Currency (after any premium and cost of exchange) on the business day in the country of issue of the Designated Currency or in the international banking community (in the case of a composite currency) immediately following the day on which such Holder receives such payment; (c) if the amount in the Designated Currency that may be so purchased for any reason falls short of the amount originally due, the Company shall pay such additional amounts as may be necessary to compensate for such shortfall; and (d) any obligation 32 39 of the Company not discharged by such payment shall be due as a separate and independent obligation and, until discharged as provided herein, shall continue in full force and effect. ARTICLE III REDEMPTION OF DEBT SECURITIES Section 3.01. APPLICABILITY OF ARTICLE. The provisions of this Article shall be applicable to the Debt Securities of any series which are redeemable before their Stated Maturity except as otherwise specified as contemplated by Section 2.03 for Debt Securities of such series. Section 3.02. TAX REDEMPTION; SPECIAL TAX REDEMPTION. (a) Unless otherwise specified pursuant to Section 2.03, Bearer Securities of any series may be redeemed at the option of the Company in whole, but not in part, at any time, on giving not less than 30 or more than 60 days' notice in accordance with Section 3.03 (which notice shall be irrevocable), at the redemption price thereof (calculated without premium), if the Company has or will become obligated to pay additional interest on such Bearer Securities pursuant to Section 4.06 as a result of any change in, or amendment to, the laws (or any regulations or rulings promulgated thereunder) of the United States or any political subdivision or taxing authority thereof or therein, or any change in the application or official interpretation of such laws, regulations or rulings, which change or amendment becomes effective on or after the date on which any Person (including any Person acting as underwriter, broker or dealer) agrees to purchase any of such Bearer Securities pursuant to their original issuance, and such obligation cannot be avoided by the Company taking reasonable measures available to it; provided, that no such notice of redemption shall be given earlier than 90 days prior to the earliest date on which the Company would be obligated to pay such additional interest were a payment in respect of the Bearer Securities of that series then due. Prior to the publication of any notice of redemption pursuant to this Section 3.02(a), the Company shall deliver to the Trustee (i) an Officers' Certificate stating that the Company is entitled to effect such redemption and setting forth a statement of facts showing that the conditions precedent to the right of the Company so to redeem have occurred and (ii) an Opinion of Counsel to the effect that the Company has or will become obligated to pay such additional interest as a result of such change or amendment. (b) Unless otherwise specified pursuant to Section 2.03, if the Company shall determine that any payment made outside the United States by the Company or any of its paying agents in respect of any Bearer Security or Coupon would, under any present or future laws or regulations of the United States, be subject to any certification, documentation, information or other reporting requirement of any kind, the effect of which requirement is the disclosure to the Company, any paying agent or any governmental authority of the nationality, residence or identity of a beneficial owner of such Bearer Security or Coupon that is a United States Alien (other than such a requirement (i) that would not be applicable to a payment made by the Company or any one of its paying agents (A) directly to the beneficial owner or (B) to a custodian, nominee or other agent of the beneficial owner, or (ii) that can be satisfied by such custodian, nominee or other agent certifying to the effect that the beneficial owner is a United States Alien; provided, that, in any case referred to in clause (i)(B) or (ii), payment by the custodian, nominee or agent to the beneficial owner is not 33 40 otherwise subject to any such requirement), then the Company shall elect either (A) to redeem such Bearer Security or Coupon in whole, but not in part, at the redemption price thereof (calculated without premium) or (B) if the conditions of the next succeeding paragraph are satisfied, to pay the additional interest specified in such paragraph. The Company shall make such determination as soon as practicable and publish prompt notice thereof (the "Determination Notice"), stating the effective date of such certification, documentation, information or other reporting requirement, whether the Company elects to redeem the Bearer Security or Coupon or to pay the additional interest specified in the next succeeding paragraph and (if applicable) the last date by which the redemption of the Bearer Security or Coupon must take place, as provided in the next succeeding sentence. If any Bearer Security or Coupon is to be redeemed pursuant to this paragraph, the redemption shall take place on such date, not later than one year after the publication of the Determination Notice, as the Company shall specify by notice given to the Trustee at least 60 days before the redemption date. Notice of such redemption shall be given by the Company to the Holders of the Bearer Security or Coupon not more than 60 days or less than 30 days prior to the redemption date. Notwithstanding the foregoing, the Company shall not so redeem the Bearer Security or Coupon if the Company shall subsequently determine, not less than 30 days prior to the redemption date, that subsequent payments on the Bearer Security or Coupon would not be subject to any such certification, documentation, information or other reporting requirement, in which case the Company shall publish prompt notice of such subsequent determination, and any earlier redemption notice given pursuant to this paragraph shall be revoked and of no further effect. Prior to the publication of any Determination Notice pursuant to this paragraph, the Company shall deliver to the Trustee (1) an Officers' Certificate stating that the Company is entitled to make such determination and setting forth a statement of facts showing that the conditions precedent to the obligation of the Company to redeem the Bearer Security or Coupon or to pay the additional interest specified in the next succeeding paragraph have occurred and (2) an Opinion of Counsel to the effect that such conditions have occurred. If and so long as the certification, documentation, information or other reporting requirement referred to in the preceding paragraph would be fully satisfied by payment of a backup withholding tax or similar charge, the Company may elect to pay as additional interest such amounts as may be necessary so that every net payment made outside the United States following the effective date of such requirement by the Company or any of its paying agents in respect of any Bearer Security or Coupon of which the beneficial owner is a United States Alien (but without any requirement that the nationality, residence or identity of such beneficial owner be disclosed to the Company, any paying agent or any governmental authority), after deduction or withholding for or on account of such backup withholding tax or similar charge that (x) would not be applicable in the circumstances referred to in the parenthetical clause of the first sentence of the preceding paragraph or (y) is imposed as a result of presentation of any such Bearer Security or Coupon for payment more than 15 days after the date on which such payment became due and payable or on which payment thereof was duly provided for, whichever occurred later), will not be less than the amount provided in any such Bearer Security or Coupon to be then due and payable. If the Company elects to pay additional interest pursuant to this paragraph, the Company shall have the right to redeem the Bearer Security or Coupon at any time in whole, but not in part, at the redemption price thereof (calculated without premium), subject to the provisions of the last three sentences of the immediately preceding paragraph. If the Company elects to pay additional interest pursuant to this paragraph and the condition specified in the first sentence of this paragraph should no longer be satisfied, then the 34 41 Company shall redeem the Bearer Security or Coupon in whole, but not in part, at the redemption price thereof (calculated without premium), subject to the provisions of the last three sentences of the immediately preceding paragraph. Any redemption payments made by the Company pursuant to the two immediately preceding sentences shall be subject to the continuing obligation of the Company to pay additional interest pursuant to this paragraph. If the Company elects to, or is required to, redeem the Bearer Security or Coupon pursuant to this paragraph, it shall publish prompt notice thereof. If the Bearer Security or Coupon is to be redeemed pursuant to this paragraph, the redemption shall take place on such date, not later than one year after publication of the notice of redemption, as the Company shall specify by notice to the Trustee at least 60 days prior to the redemption date. Section 3.03. NOTICE OF REDEMPTION; SELECTION OF DEBT SECURITIES. In case the Company shall desire to exercise the right to redeem all or, as the case may be, any part of the Debt Securities of any series in accordance with their terms, a resolution of the Board of Directors of the Company or a supplemental Indenture, the Company shall fix a date for redemption and shall give notice of such redemption at least 30 and not more than 60 days prior to the date fixed for redemption to the Holders of Debt Securities of such series so to be redeemed as a whole or in part, in the manner provided in Section 13.03. The notice if given in the manner herein provided shall be conclusively presumed to have been duly given, whether or not the Holder receives such notice. In any case, failure to give such notice or any defect in the notice to the Holder of any Debt Security of a series designated for redemption as a whole or in part shall not affect the validity of the proceedings for the redemption of any other Debt Security of such series. Each such notice of redemption shall specify the date fixed for redemption, the redemption price at which Debt Securities of such series are to be redeemed, the Place or Places of Payment that payment will be made upon presentation and surrender of such Debt Securities, that any interest accrued to the date fixed for redemption will be paid as specified in said notice, that the redemption is for a sinking fund payment (if applicable), that, unless otherwise specified in such notice, Coupon Securities of any series, if any, surrendered for redemption must be accompanied by all Coupons maturing subsequent to the date fixed for redemption, failing which the amount of any such missing Coupon or Coupons will be deducted from the redemption price, if the Bearer Securities of any series are to be redeemed and any Registered Securities of such series are not to be redeemed, and if such Bearer Securities may be exchanged for Registered Securities not subject to redemption on the applicable redemption date pursuant to Section 2.15(c) or otherwise, the last date on which such exchanges may be made, that, if the Company defaults in making such redemption payment or if the Debt Securities of that series are subordinated pursuant to the terms of Article XII, the paying agent is prohibited from making such payment pursuant to the terms of this Indenture, that on and after said date any interest thereon or on the portions thereof to be redeemed will cease to accrue, that in the case of Original Issue Discount Securities original issue discount accrued after the date fixed for redemption will cease to accrue, the terms of the Debt Securities of that series pursuant to which the Debt Securities of that series are being redeemed and that no representation is made as to the correctness or accuracy of the CUSIP number, if any, listed in such notice or printed on the Debt Securities of that series. If less than all the Debt Securities of a series are to be redeemed the notice of redemption shall specify the CUSIP numbers of the Debt Securities of that series to be redeemed. In case any Debt Security of a series is to be redeemed in part only, the notice of redemption shall 35 42 state the portion of the principal amount thereof to be redeemed and shall state that on and after the date fixed for redemption, upon surrender of such Debt Security, a new Debt Security or Debt Securities of that series in principal amount equal to the unredeemed portion thereof, and in the case of a Bearer Security with appropriate Coupons, if any, will be issued. At least 60 days before the redemption date unless the Trustee consents to a shorter period, the Company shall give notice to the Trustee of the redemption date, the principal amount of Debt Securities to be redeemed and the series and terms of the Debt Securities pursuant to which such redemption will occur. Such notice shall be accompanied by an Officers' Certificate and an Opinion of Counsel from the Company to the effect that such redemption will comply with the conditions herein. If fewer than all the Debt Securities of a series are to be redeemed, the record date relating to such redemption shall be selected by the Company and given to the Trustee, which record date shall be not less than 15 days after the date of notice to the Trustee. On or prior to the redemption date for any Registered Securities, the Company shall deposit with the Trustee or with a paying agent (or, if the Company is acting as its own paying agent, segregate and hold in trust) an amount of money in the Currency in which such Debt Securities are denominated (except as provided pursuant to Section 2.03) sufficient to pay the redemption price of such Registered Securities or any portions thereof that are to be redeemed on that date. In the case of any redemption pertaining to Bearer Securities or Coupon Securities, the Company shall, no later than the business day prior to such redemption date, deposit with the Trustee or with a paying agent (other than the Company) an amount of money in the Currency in which such Debt Securities are denominated (except as provided pursuant to Section 2.03) sufficient to pay the redemption price of such Bearer or Coupon Securities or any portion thereof that are to be redeemed on the redemption date. If less than all the Debt Securities of like tenor and terms of a series are to be redeemed (other than pursuant to mandatory sinking fund redemptions) the Trustee shall select, in such manner as in its sole discretion it shall deem appropriate and fair, the Debt Securities of that series or portions thereof (in multiples of $1,000) to be redeemed. In any case where more than one Registered Security of such series is registered in the same name, the Trustee in its discretion may treat the aggregate principal amount so registered as if it were represented by one Registered Security of such series. The Trustee shall promptly notify the Company in writing of the Debt Securities selected for redemption and, in the case of any Debt Securities selected for partial redemption, the principal amount thereof to be redeemed. If any Debt Security called for redemption shall not be so paid upon surrender thereof on such redemption date, the principal, premium, if any, and interest shall bear interest until paid from the redemption date at the rate borne by the Debt Securities of that series. If less than all the Debt Securities of unlike tenor and terms of a series are to be redeemed, the particular Debt Securities to be redeemed shall be selected by the Company. Provisions of this Indenture that apply to Debt Securities called for redemption also apply to portions of Debt Securities called for redemption. Section 3.04. PAYMENT OF DEBT SECURITIES CALLED FOR REDEMPTION. If notice of redemption has been given as provided in Section 3.03, the Debt Securities or portions of Debt Securities of the series with respect to which such notice has been given shall become due and 36 43 payable on the date and at the Place or Places of Payment stated in such notice at the applicable redemption price, together with any interest accrued to the date fixed for redemption, and on and after said date (unless the Company shall default in the payment of such Debt Securities at the applicable redemption price, together with any interest accrued to said date) any interest on the Debt Securities or portions of Debt Securities of any series so called for redemption shall cease to accrue, any original issue discount in the case of Original Issue Discount Securities shall cease to accrue and any Coupons for such interest appertaining to any Coupon Securities to be redeemed, except to the extent described below, shall be void. On presentation and surrender of such Debt Securities at the Place or Places of Payment in said notice specified, the said Debt Securities or the specified portions thereof shall be paid and redeemed by the Company at the applicable redemption price, together with any interest accrued thereon to the date fixed for redemption. If any Coupon Security surrendered for redemption shall not be accompanied by all Coupons appertaining thereto maturing on or after the applicable redemption date, the redemption price for such Coupon Security may be reduced by an amount equal to the face amount of all such missing Coupons. If thereafter the Holder of such Coupon shall surrender to any paying agent outside the United States any such missing Coupon in respect of which a deduction shall have been made from the redemption price, such Holder shall be entitled to receive the amount so deducted. The surrender of such missing Coupon or Coupons may be waived by the Company and the Trustee, if there be furnished to them such security or indemnity as they may require to save each of them and any paying agent harmless. Any Debt Security that is to be redeemed only in part shall be surrendered at the corporate trust office or such other office or agency of the Company as is specified pursuant to Section 2.03 (in the case of Registered Securities) and at the principal London office of the Trustee or such other office or agency of the Company outside the United States as is specified pursuant to Section 2.03 (in the case of Bearer Securities) with, if the Company, the Registrar or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company, the Registrar and the Trustee duly executed by, the Holder thereof or his attorney duly authorized in writing, and the Company shall execute, and the Trustee shall authenticate and deliver to the Holder of such Debt Security without service charge, a new Debt Security or Debt Securities of the same series, of like tenor and form, of any authorized denomination as requested by such Holder in aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the Debt Security so surrendered, and, in the case of a Coupon Security, with appropriate Coupons attached; except that if a Global Security is so surrendered, the Company shall execute, and the Trustee shall authenticate and deliver to the Depositary for such Global Security, without service charge, a new Global Security in a denomination equal to and in exchange for the unredeemed portion of the principal of the Global Security so surrendered. In the case of a Debt Security providing appropriate space for such notation, at the option of the Holder thereof, the Trustee, in lieu of delivering a new Debt Security or Debt Securities as aforesaid, may make a notation on such Debt Security of the payment of the redeemed portion thereof. Section 3.05. MANDATORY AND OPTIONAL SINKING FUNDS. The minimum amount of any sinking fund payment provided for by the terms of Debt Securities of any series, resolution of the Board of Directors or a supplemental Indenture is herein referred to as a "mandatory sinking fund 37 44 payment", and any payment in excess of such minimum amount provided for by the terms of Debt Securities of any series, resolution of the Board of Directors or a supplemental Indenture is herein referred to as an "optional sinking fund payment". In lieu of making all or any part of any mandatory sinking fund payment with respect to any Debt Securities of a series in cash, the Company may at its option (a) deliver to the Trustee Debt Securities of that series (together with the unmatured Coupons, if any, appertaining thereto) theretofore purchased or otherwise acquired by the Company or (b) receive credit for the principal amount of Debt Securities of that series which have been redeemed either at the election of the Company pursuant to the terms of such Debt Securities or through the application of permitted optional sinking fund payments pursuant to the terms of such Debt Securities, resolution or supplemental Indenture; provided, that such Debt Securities have not been previously so credited. Such Debt Securities shall be received and credited for such purpose by the Trustee at the redemption price specified in such Debt Securities, resolution or supplemental Indenture for redemption through operation of the sinking fund and the amount of such mandatory sinking fund payment shall be reduced accordingly. Section 3.06. REDEMPTION OF DEBT SECURITIES FOR SINKING FUND. Not less than 60 days prior to each sinking fund payment date for any series of Debt Securities, the Company will deliver to the Trustee an Officers' Certificate specifying the amount of the next ensuing sinking fund payment for that series pursuant to the terms of that series, any resolution or supplemental Indenture, the portion thereof, if any, which is to be satisfied by payment of cash in the Currency in which the Debt Securities of such series are denominated (except as provided pursuant to Section 2.03) and the portion thereof, if any, which is to be satisfied by delivering and crediting Debt Securities of that series pursuant to this Section 3.06 (which Debt Securities, if not previously redeemed, will accompany such certificate) and whether the Company intends to exercise its right to make any permitted optional sinking fund payment with respect to such series. Such certificate shall also state that no Event of Default has occurred and is continuing with respect to such series. Such certificate shall be irrevocable and upon its delivery the Company shall be obligated to make the cash payment or payments therein referred to, if any, on or before the next succeeding sinking fund payment date. Failure of the Company to deliver such certificate (or to deliver the Debt Securities and Coupons, if any, specified in this paragraph) shall not constitute a Default, but such failure shall require that the sinking fund payment due on the next succeeding sinking fund payment date for that series shall be paid entirely in cash and shall be sufficient to redeem the principal amount of such Debt Securities subject to a mandatory sinking fund payment without the option to deliver or credit Debt Securities as provided in this Section 3.06 and without the right to make any optional sinking fund payment, if any, with respect to such series. Any sinking fund payment or payments (mandatory or optional) made in cash plus any unused balance of any preceding sinking fund payments made in cash which shall equal or exceed $100,000 (or a lesser sum if the Company shall so request) with respect to the Debt Securities of any particular series shall be applied by the Trustee on the sinking fund payment date on which such payment is made (or, if such payment is made before a sinking fund payment date, on the sinking fund payment date following the date of such payment) to the redemption of such Debt Securities at the Redemption Price specified in such Debt Securities, resolution or supplemental Indenture for 38 45 operation of the sinking fund together with any accrued interest to the date fixed for redemption. Any sinking fund moneys not so applied or allocated by the Trustee to the redemption of Debt Securities shall be added to the next cash sinking fund payment received by the Trustee for such series and, together with such payment, shall be applied in accordance with the provisions of this Section 3.06. Any and all sinking fund moneys with respect to the Debt Securities of any particular series held by the Trustee on the last sinking fund payment date with respect to Debt Securities of such series and not held for the payment or redemption of particular Debt Securities shall be applied by the Trustee, together with other moneys, if necessary, to be deposited sufficient for the purpose, to the payment of the principal of the Debt Securities of that series at its Stated Maturity. The Trustee shall select the Debt Securities to be redeemed upon such sinking fund payment date in the manner specified in the last paragraph of Section 3.03 and the Company shall cause notice of the redemption thereof to be given in the manner provided in Section 3.03 except that the notice of redemption shall also state that the Debt Securities are being redeemed by operation of the sinking fund. Such notice having been duly given, the redemption of such Debt Securities shall be made upon the terms and in the manner stated in Section 3.04. At least one business day before each sinking fund payment date, the Company shall pay to the Trustee (or, if the Company is acting as its own paying agent, the Company shall segregate and hold in trust) in cash a sum in the Currency in which the Debt Securities of such series are denominated (except as provided pursuant to Section 2.03) equal to any interest accrued to the date fixed for redemption of Debt Securities or portions thereof to be redeemed on such sinking fund payment date pursuant to this Section 3.06. The Trustee shall not redeem any Debt Securities of a series with sinking fund moneys or mail any notice of redemption of such Debt Securities by operation of the sinking fund for such series during the continuance of a Default in payment of interest on such Debt Securities or of any Event of Default (other than an Event of Default occurring as a consequence of this paragraph) with respect to such Debt Securities, except that if the notice of redemption of any such Debt Securities shall theretofore have been mailed in accordance with the provisions hereof, the Trustee shall redeem such Debt Securities if cash sufficient for that purpose shall be deposited with the Trustee for that purpose in accordance with the terms of this Article III. Except as aforesaid, any moneys in the sinking fund for such series at the time when any such Default or Event of Default shall occur and any moneys thereafter paid into such sinking fund shall, during the continuance of such Default or Event of Default, be held as security for the payment of such Debt Securities; provided, however, that in case such Event of Default or Default shall have been cured or waived as provided herein, such moneys shall thereafter be applied on the next sinking fund payment date for such Debt Securities on which such moneys may be applied pursuant to the provisions of this Section 3.06. 39 46 ARTICLE IV PARTICULAR COVENANTS OF THE COMPANY Section 4.01. PAYMENT OF PRINCIPAL OF, AND PREMIUM, IF ANY, AND INTEREST ON, DEBT SECURITIES. The Company, for the benefit of each series of Debt Securities, will duly and punctually pay or cause to be paid the principal of, and premium, if any, and interest on, each of the Debt Securities and pay any Coupons at the place, at the respective times and in the manner provided herein, in the Debt Securities and in the Coupons. Each installment of interest on the Debt Securities may at the Company's option be paid by mailing checks for such interest payable to the Person entitled thereto pursuant to Section 2.07(a) to the address of such Person as it appears on the Debt Security Register. Any interest due on Coupon Securities on or before the Stated Maturity of the related Debt Security, other than additional interest, if any, payable as provided in Section 4.06 in respect of principal of, or premium, if any, on such a Debt Security, shall be payable only upon presentation and surrender of the several Coupons for such interest installments as are evidenced thereby as they severally mature. Principal, premium and interest of Debt Securities of any series shall be considered paid on the date due if on such date the Trustee or any paying agent holds in accordance with this Indenture money sufficient to pay in the Currency in which the Debt Securities of such series are denominated (except as provided pursuant to Section 2.03) all principal, premium and interest then due and, in the case of Debt Securities subordinated pursuant to the terms of Article XII, the Trustee or such paying agent, as the case may be, is not prohibited from paying such money to the Holders on that date pursuant to the terms of this Indenture. The Company shall pay interest on overdue principal at the rate specified therefor in the Debt Securities and it shall pay interest on overdue installments of interest at the same rate to the extent lawful. Section 4.02. MAINTENANCE OF OFFICES OR AGENCIES FOR REGISTRATION OF TRANSFER, EXCHANGE AND PAYMENT OF DEBT SECURITIES. The Company will maintain in each Place of Payment for any series of Debt Securities and Coupons, if any, an office or agency where Debt Securities and Coupons of such series (but, except as otherwise provided in Section 2.12, unless such Place of Payment is located outside the United States, not Bearer Securities or Coupons) may be presented or surrendered for payment, where Debt Securities of such series may be surrendered for transfer or exchange and where notices and demands to or upon the Company in respect of the Debt Securities and Coupons of such series and this Indenture may be served. So long as any Bearer Securities of any series remain outstanding, the Company will maintain for such purposes one or more offices or agencies outside the United States in such city or cities specified pursuant to Section 2.03 and, if any Bearer Securities are listed on a securities exchange that requires an office or agency for the payment of principal of, and premium, if any, or interest on, such Bearer Securities in a location other than the location of an office or agency specified pursuant to Section 2.03, the Company will maintain for such purposes an office or agency in such location so long as any Bearer Securities are listed on such securities exchange and such exchange so requires. The Company will give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at 40 47 any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the corporate trust office of the Trustee (in the case of Registered Securities) and at the principal London office of the Trustee (in the case of Bearer Securities), and the Company hereby appoints the Trustee as its agent to receive all presentations, surrenders, notices and demands. The Company may also from time to time designate different or additional offices or agencies to be maintained for such purposes (in or outside of such Place of Payment), and may from time to time rescind any such designation; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligations described in the preceding paragraph. The Company will give prompt written notice to the Trustee of any such additional designation or rescission of designation and any change in the location of any such different or additional office or agency. Section 4.03. APPOINTMENT TO FILL A VACANCY IN THE OFFICE OF TRUSTEE. The Company, whenever necessary to avoid or fill a vacancy in the office of Trustee, will appoint, in the manner provided in Section 7.10, a Trustee, so that there shall at all times be a Trustee hereunder with respect to each series of Debt Securities. Section 4.04. DUTIES OF PAYING AGENTS, ETC. (a) The Company shall cause each paying agent, if any, other than the Trustee, to execute and deliver to the Trustee an instrument in which such agent shall agree with the Trustee, subject to the provisions of this Section 4.04, (i) that it will hold all sums held by it as such agent for the payment of the principal of, and premium, if any, or interest on, the Debt Securities of any series and the payment of any related Coupons (whether such sums have been paid to it by the Company or by any other obligor on the Debt Securities or Coupons of such series) in trust for the benefit of the Holders of the Debt Securities and Coupons of such series; (ii) that it will give the Trustee notice of any failure by the Company (or by any other obligor on the Debt Securities or Coupons of such series) to make any payment of the principal of, and premium, if any, or interest on, the Debt Securities of such series or any payment on any related Coupons when the same shall be due and payable; and (iii) that it will at any time during the continuance of an Event of Default, upon the written request of the Trustee, forthwith pay to the Trustee all sums so held by it as such agent. (b) If the Company shall act as its own paying agent, it will, on or before each due date of the principal of, and premium, if any, or interest on, the Debt Securities and Coupons, if any, of any series, set aside, segregate and hold in trust for the benefit of the Holders of the Debt Securities and Coupons of such series a sum sufficient to pay such principal, premium, if any, or interest so becoming due. The Company will promptly notify the Trustee of any failure by the Company to take such action or the failure by any other obligor on such Debt Securities or Coupons 41 48 to make any payment of the principal of, and premium, if any, or interest on, such Debt Securities or Coupons when the same shall be due and payable. (c) Anything in this Section 4.04 to the contrary notwithstanding, the Company may, at any time, for the purpose of obtaining a satisfaction and discharge of this Indenture, or for any other reason, pay or cause to be paid to the Trustee all sums held in trust by it or any paying agent, as required by this Section 4.04, such sums to be held by the Trustee upon the same trusts as those upon which such sums were held by the Company or such paying agent. (d) Whenever the Company shall have one or more paying agents with respect to any series of Debt Securities and Coupons, it will, prior to each due date of the principal of, and premium, if any, or interest on, any Debt Securities of such series, deposit with any such paying agent a sum sufficient to pay the principal, premium or interest so becoming due, such sum to be held in trust for the benefit of the Persons entitled thereto, and (unless any such paying agent is the Trustee) the Company will promptly notify the Trustee of its action or failure so to act. (e) Anything in this Section 4.04 to the contrary notwithstanding, the agreement to hold sums in trust as provided in this Section 4.04 is subject to the provisions of Section 11.05. Section 4.05. STATEMENT BY OFFICERS AS TO DEFAULT. The Company will deliver to the Trustee, on or before a date not more than four months after the end of each fiscal year of the Company (currently on a calendar year basis) ending after the date hereof, an Officers' Certificate stating, as to each officer signing such certificate, that (a) in the course of his performance of his duties as an officer of the Company he would normally have knowledge of any Default, (b) whether or not to the best of his knowledge any Default occurred during such year and (c) if to the best of his knowledge the Company is in Default, specifying all such Defaults and what action the Company is taking or proposes to take with respect thereto.

Unless otherwise provided pursuant to Section 2.03, the provisions of this Section 4.06 shall be applicable to Bearer Securities of any series. The Company will, subject to the exceptions and limitations set forth below, pay as additional interest to the Holder of any Bearer Security or Coupon that is a United States Alien such amounts as may be necessary so that every net payment on such Bearer Security or Coupon, after deduction or withholding for or on account of any present or future tax, assessment or other governmental charge imposed upon or as a result of such payment by the United States (or any political subdivision or taxing authority thereof or therein), will not be less than the amount provided in such Bearer Security or Coupon to be then due and payable. However, the Company will not be required to make any such payment of additional interest for or on account of: (a) any tax, assessment or other governmental charge that would not have been imposed but for (i) the existence of any present or former connection between such Holder (or between a fiduciary, settlor or beneficiary of, or a Person holding a power over, such Holder, if such Holder is an estate or a trust, or a member or shareholder of such Holder, if such Holder is a 42 49 partnership or corporation) and the United States, including such Holder (or such fiduciary, settlor, beneficiary, Person holding a power, member or shareholder) being or having been a citizen or resident thereof or being or having been engaged in trade or business or present therein or having or having had a permanent establishment therein or (ii) such Holder's past or present status for United States Federal income tax purposes as a personal holding company, foreign personal holding company or private foundation or other tax-exempt organization with respect to the United States or as a corporation that accumulates earnings to avoid United States Federal income tax; (b) any estate, inheritance, gift, sales, transfer or personal property tax or any similar tax, assessment or other governmental charge; (c) any tax, assessment or other governmental charge that would not have been imposed but for the presentation by the Holder of a Bearer Security or Coupon for payment more than 15 days after the date on which such payment became due and payable or on which payment thereof was duly provided for, whichever occurs later; (d) any tax, assessment or other governmental charge that is payable otherwise than by deduction or withholding from a payment on a Bearer Security or Coupon; (e) any tax, assessment or other governmental charge that would not have been imposed but for a failure to comply with applicable certification, documentation, information or other reporting requirement concerning the nationality, residence, identity or connection with the United States of the Holder or beneficial owner of a Bearer Security or Coupon if, without regard to any tax treaty, such compliance is required by statute or regulation of the United States as a precondition to relief or exemption from such tax, assessment or other governmental charge; or (f) any tax, assessment or other governmental charge imposed on a Holder that actually or constructively owns ten percent or more of the combined voting power of all classes of stock of the Company or that is a controlled foreign corporation related to the Company through stock ownership; nor shall additional interest be paid with respect to a payment on a Bearer Security or Coupon to a Holder that is a fiduciary or partnership or other than the sole beneficial owner of such payment to the extent a beneficiary or settlor with respect to such fiduciary or a member of such partnership or a beneficial owner would not have been entitled to the additional interest had such beneficiary, settlor, member or beneficial owner been the Holder of such Bearer Security or Coupon. Whenever in this Indenture there is mentioned, in any context, the payment of the principal of, or premium, if any, or interest on, any Debt Security or payment with respect to any Coupon of any series, such mention shall be deemed to include mention of the payment of additional interest provided for in the terms of such Debt Securities and this Section 4.06 to the extent that, in such context, additional interest is, was or would be payable in respect thereof pursuant to the provisions of this Section 4.06 and express mention of the payment of additional interest (if applicable) in any provisions hereof shall not be construed as excluding additional interest in those provisions hereof where such express mention is not made. 43 50 If the payment of additional interest becomes required in respect of the Debt Securities or Coupons of a series, at least ten days prior to the first interest payment date with respect to which such additional interest will be payable (or if the Debt Securities of that series will not bear interest prior to its Stated Maturity, the first day on which a payment of principal, and premium, if any, is made and on which such additional interest will be payable), and at least ten days prior to each date of payment of principal, and premium, if any, or interest if there has been any change with respect to the matters set forth in the below-mentioned Officers' Certificate, the Company will furnish the Trustee and each paying agent with an Officers' Certificate that shall specify by country the amount, if any, required to be withheld on such payments to Holders of Debt Securities or Coupons that are United States Aliens, and the Company will pay to the Trustee or such paying agent the additional interest, if any, required by the terms of such Debt Securities and this Section 4.06. The Company covenants to indemnify the Trustee and any paying agent for, and to hold them harmless against, any loss, liability or expense reasonably incurred without negligence or bad faith on their part arising out of or in connection with actions taken or omitted by any of them in reliance on any Officers' Certificate furnished pursuant to this Section 4.06.

Section 4.08. EXISTENCE. Subject to Article X, the Company will do or cause to be done all things necessary to preserve and keep in full force and effect its existence, rights (charter and statutory) and franchises; provided, however, that the Company shall not be required to preserve any such right or franchise if the Board of Directors shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Company and that the loss thereof is not disadvantageous in any material respect to the Holders. Section 4.09. MAINTENANCE OF PROPERTIES. The Company will cause all properties used or useful in the conduct of its business or the business of any Subsidiary to be maintained and kept in good condition, repair and working order and supplied with all necessary equipment and will cause to be made all necessary repairs, renewals, replacements, betterments and improvements thereof, all as in the judgment of the Company may be necessary so that the business carried on in connection therewith may be properly and advantageously conducted at all times; provided, however, that nothing in this Section shall prevent the Company from discontinuing the operation or maintenance of any of such properties if such discontinuance is, in the judgment of the Company, desirable in the conduct of its business or the business of any Subsidiary and not disadvantageous in any material respect to the Holders. Section 4.10. PAYMENT OF TAXES AND OTHER CLAIMS. The Company will pay or discharge or cause to be paid or discharged, before the same shall become delinquent, (a) all taxes, assessments and governmental charges levied or imposed upon the Company or any Subsidiary or upon the income, profits or property of the Company or any Subsidiary, and (b) all lawful claims for labor, materials and supplies which, if unpaid, might by law become a lien upon the property of the Company or any Subsidiary; provided, however, that the Company shall not be required to pay or 44 51 discharge or cause to be paid or discharged any such tax, assessment, charge or claim whose amount, applicability or validity is being contested in good faith by appropriate proceedings. Section 4.11. LIMITATION ON LIENS. The Company shall not, and shall not permit any of its Subsidiaries to, directly or indirectly, create or permit to exist any Lien on any Restricted Property, whether owned on the Issue Date or thereafter acquired, securing any obligation unless the Company contemporaneously secures the Debt Securities equally and ratably with (or prior to) such obligation. The preceding sentence shall not require the Company to secure the Debt Securities if the Lien consists of the following: (a) Permitted Liens; or (b) Liens securing Indebtedness if, after giving pro forma effect to the Incurrence of such Indebtedness (and the receipt and application of the proceeds thereof) or the securing of outstanding Indebtedness, the sum of (without duplication) (i) all Indebtedness of the Company and its Subsidiaries secured by Liens on Restricted Property (other than Permitted Liens) and (ii) all Attributable Indebtedness in respect of Sale/Leaseback Transactions with respect to any Restricted Property, at the time of determination does not exceed 10% of Consolidated Net Tangible Assets. Section 4.12. LIMITATION ON SALE/LEASEBACK TRANSACTIONS.

Section 6.02. COLLECTION OF INDEBTEDNESS BY TRUSTEE, ETC.

In case there shall be pending proceedings for the bankruptcy or for the reorganization of the Company or any other obligor upon the Debt Securities and Coupons, if any, of any series under Title 11 of the United States Code or any other Federal or State bankruptcy, insolvency or similar law, or in case a receiver, trustee or other similar official shall have been appointed for its property, or in case of any other similar judicial proceedings relative to the Company or any other obligor upon the Debt Securities of any series, its creditors or its property, the Trustee, irrespective of whether the principal of Debt Securities and Coupons, if any, of any series shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand pursuant to the provisions of this Section 6.02, shall be entitled and empowered, by intervention in such proceedings or otherwise, to file and prove a claim or claims for the whole amount of principal, premium, if any, and interest (or, if the Debt Securities of such series are Original Issue Discount Debt Securities, such portion of the principal amount as may be specified in the terms of such series) owing and unpaid in respect of the Debt Securities and Coupons of such series, and to file such other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for reasonable compensation to the Trustee, its agents, attorneys and counsel, and for reimbursement of all expenses and liabilities Incurred, and all advances made, by the Trustee except as a result of its negligence or bad faith) and of the Holders thereof allowed in any such judicial proceedings relative to the Company, or any other obligor upon the Debt Securities and Coupons of such series, its creditors or its property, and to collect and receive any moneys or other property payable or deliverable on any such claims, and to distribute all amounts received with respect to the claims of such Holders and of the Trustee on their behalf, and any receiver, assignee or trustee in bankruptcy or reorganization is hereby authorized by each of such Holders to make payments to the Trustee, and, in the event that the Trustee shall consent to the making of payments directly to such Holders, to pay to the Trustee such amount as shall be sufficient to cover reasonable compensation to the Trustee, its agents, attorneys and counsel, and all other reasonable expenses and liabilities Incurred, and all advances made, by the Trustee except as a result of its negligence or bad faith. All rights of action and of asserting claims under this Indenture, or under any of the Debt Securities and the Coupons, if any, appertaining thereto, of any series, may be enforced by the Trustee without the possession of any such Debt Securities or Coupons, or the production thereof in any trial or other proceedings relative thereto, and any such action or proceedings instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment (except for any amounts payable to the Trustee pursuant to Section 7.06) shall be for the ratable benefit of the Holders of all the Debt Securities or Coupons in respect of which such action was taken. In case of an Event of Default hereunder the Trustee may in its discretion proceed to protect and enforce the rights vested in it by this Indenture by such appropriate judicial proceedings as the 51 58 Trustee shall deem most effectual to protect and enforce any of such rights, either at law or in equity or in bankruptcy or otherwise, whether for the specific enforcement of any covenant or agreement contained in this Indenture or in aid of the exercise of any power granted in this Indenture, or to enforce any other legal or equitable right vested in the Trustee by this Indenture or by law.

Any moneys or other property collected by the Trustee pursuant to Section 6.02 with respect to Debt Securities and Coupons, if any, of any series shall be applied, after giving effect to the provisions of Article XII, if applicable, in the order following, at the date or dates fixed by the Trustee for the distribution of such moneys or other property, upon presentation of the several Debt Securities or Coupons of such series in respect of which moneys or other property have been collected, and the notation thereon of the payment, if only partially paid, and upon surrender thereof if fully paid: FIRST: To the payment of all money due the Trustee pursuant to Section 7.06; SECOND: In case the principal of the Outstanding Debt Securities in respect of which such moneys have been collected shall not have become due, to the payment of interest on the Debt Securities or Coupons of such series in the order of the maturity of the installments of such interest, with interest (to the extent that such interest has been collected by the Trustee) upon the overdue installments of interest at the rate or Yield to Maturity (in the case of Original Issue Discount Debt Securities) borne by the Debt Securities or Coupons of such series, such payments to be made ratably to the Persons entitled thereto, without discrimination or preference; THIRD: In case the principal of the Outstanding Debt Securities in respect of which such moneys have been collected shall have become due, by declaration or otherwise, to the payment of the whole amount then owing and unpaid upon the Debt Securities or Coupons of such series for principal and premium, if any, and interest, with interest on the overdue principal and premium, if any, and (to the extent that such interest has been collected by the Trustee) upon overdue installments of interest at the rate or Yield to Maturity (in the case of Original Issue Discount Debt Securities) borne by the Debt Securities or Coupons of such series; and, in case such moneys shall be insufficient to pay in full the whole amount so due and unpaid upon the Debt Securities and Coupons of such series, then to the payment of such principal and premium, if any, and interest, without preference or priority of principal and premium, if any, over interest, or of interest over principal and premium, if any, or of any installment of interest over any other installment of interest, or of any Debt Security or Coupon of such series over any Debt Security or Coupon of such series, ratably to the aggregate of such principal and premium, if any, and interest; and FOURTH: The remainder, if any, shall be paid to the Company, its successors or assigns, or to whomsoever may be lawfully entitled to receive the same, or as a court of competent jurisdiction may direct.

At least 15 days before such record date, the Company shall mail to each Holder and the Trustee a notice that states the record date, the payment date and amount to be paid. 52 59 Section 6.04. LIMITATION ON SUITS BY HOLDERS. No Holder of any Debt Security or Coupon of any series shall have any right by virtue or by availing of any provision of this Indenture to institute any action or proceeding at law or in equity or in bankruptcy or otherwise, upon or under or with respect to this Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless such Holder previously shall have given to the Trustee written notice of an Event of Default with respect to Debt Securities of that same series and of the continuance thereof and unless the Holders of not less than 25% in aggregate principal amount of the Outstanding Debt Securities of that series shall have made written request upon the Trustee to institute such action or proceedings in respect of such Event of Default in its own name as Trustee hereunder and shall have offered to the Trustee such reasonable indemnity as it may require against the costs, expenses and liabilities to be Incurred therein or thereby, and the Trustee, for 60 days after its receipt of such notice, request and offer of indemnity shall have failed to institute any such action or proceedings and no direction inconsistent with such written request shall have been given to the Trustee pursuant to Section 6.06; it being understood and intended, and being expressly covenanted by the Holder of every Debt Security or Coupon with every other Holder and the Trustee, that no one or more Holders shall have any right in any manner whatever by virtue or by availing of any provision of this Indenture to affect, disturb or prejudice the rights of any Holders, or to obtain or seek to obtain priority over or preference to any other such Holder, or to enforce any right under this Indenture, except in the manner herein provided and for the equal, ratable and common benefit of all such Holders. For the protection and enforcement of the provisions of this Section 6.04, each and every Holder and the Trustee shall be entitled to such relief as can be given either at law or in equity. Notwithstanding any other provision in this Indenture, however, the right of any Holder of any Debt Security or Coupon to receive payment of the principal of, and premium, if any, and (subject to Section 2.12) interest on, such Debt Security or Coupon, on or after the respective due dates expressed in such Debt Security, and to institute suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder. Section 6.05. REMEDIES CUMULATIVE; DELAY OR OMISSION IN EXERCISE OF RIGHTS NOT A WAIVER OF DEFAULT. All powers and remedies given by this Article VI to the Trustee or to the Holders shall, to the extent permitted by law, be deemed cumulative and not exclusive of any thereof or of any other powers and remedies available to the Trustee or the Holders, by judicial proceedings or otherwise, to enforce the performance or observance of the covenants and agreements contained in this Indenture, and no delay or omission of the Trustee or of any Holder to exercise any right or power accruing upon any Default occurring and continuing as aforesaid, shall impair any such right or power, or shall be construed to be a waiver of any such Default or an acquiescence therein; and, subject to the provisions of Section 6.04, every power and remedy given by this Article VI or by law to the Trustee or to the Holders may be exercised from time to time, and as often as shall be deemed expedient, by the Trustee or by the Holders. Section 6.06. RIGHTS OF HOLDERS OF MAJORITY IN PRINCIPAL AMOUNT OF DEBT SECURITIES TO DIRECT TRUSTEE AND TO WAIVE DEFAULT. The Holders of a majority in aggregate principal amount of the Debt Securities of any series at the time Outstanding shall have the right to direct the time, method, and place of conducting any proceeding for any remedy available to the Trustee, or 53 60 exercising any trust or power conferred on the Trustee, with respect to the Debt Securities of such series; provided, however, that such direction shall not be otherwise than in accordance with law and the provisions of this Indenture, and that subject to the provisions of Section 7.01, the Trustee shall have the right to decline to follow any such direction if the Trustee being advised by counsel shall determine that the action so directed may not lawfully be taken, or if the Trustee shall by a responsible officer or officers determine that the action so directed would involve it in personal liability or would be unjustly prejudicial to Holders of Debt Securities of such series not taking part in such direction; and provided, further, however, that nothing in this Indenture contained shall impair the right of the Trustee to take any action deemed proper by the Trustee and which is not inconsistent with such direction by such Holders. Prior to the acceleration of the maturity of the Debt Securities of any series, as provided in Section 6.01, the Holders of a majority in aggregate principal amount of the Debt Securities of that series at the time Outstanding may on behalf of the Holders of all the Debt Securities and any related Coupons of that series waive any past Default or Event of Default and its consequences for that series specified in the terms thereof as contemplated by Section 2.03, except (a) a Default in the payment of the principal of, and premium, if any, or interest on, any of the Debt Securities or in the payment of any related Coupon and (b) a Default in respect of a provision that under Section 9.02 cannot be amended without the consent of each Holder affected thereby. In case of any such waiver, such Default shall cease to exist, any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture, and the Company, the Trustee and the Holders of the Debt Securities of that series shall be restored to their former positions and rights hereunder, respectively; but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon. Section 6.07. TRUSTEE TO GIVE NOTICE OF DEFAULTS KNOWN TO IT, BUT MAY WITHHOLD SUCH NOTICE IN CERTAIN CIRCUMSTANCES. The Trustee shall, within 90 days after the occurrence of a Default known to it with respect to a series of Debt Securities or Coupons, if any, give to the Holders thereof, in the manner provided in Section 13.03, notice of all Defaults with respect to such series known to the Trustee, unless such Defaults shall have been cured or waived before the giving of such notice; provided, that, except in the case of Default in the payment of the principal of, or premium, if any, or interest on, any of the Debt Securities or Coupons of such series or in the making of any sinking fund payment with respect to the Debt Securities of such series, the Trustee shall be protected in withholding such notice if and so long as the board of directors, the executive committee or a committee of directors or responsible officers of the Trustee in good faith determine that the withholding of such notice is in the interests of the Holders thereof. Section 6.08. REQUIREMENT OF AN UNDERTAKING TO PAY COSTS IN CERTAIN SUITS UNDER THE INDENTURE OR AGAINST THE TRUSTEE. All parties to this Indenture agree, and each Holder of any Debt Security or Coupon by his acceptance thereof shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit in the manner and to the extent provided in the Trust Indenture Act, and that such court may in its discretion assess reasonable costs, including reasonable attorneys' fees, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; but the provisions of this Section 6.08 shall not apply to any suit instituted by the Trustee, to any suit instituted by any Holder, 54 61 or group of Holders, holding in the aggregate more than ten percent in principal amount of the Outstanding Debt Securities of that series or to any suit instituted by any Holder for the enforcement of the payment of the principal of, or premium, if any, or interest on, any Debt Security or Coupon on or after the due date for such payment expressed in such Debt Security or Coupon. ARTICLE VII CONCERNING THE TRUSTEE Section 7.01. CERTAIN DUTIES AND RESPONSIBILITIES. The Trustee, prior to the occurrence of an Event of Default and after the curing or waiving of all Events of Default which may have occurred, undertakes to perform such duties and only such duties as are specifically set forth in this Indenture. In case an Event of Default has occurred (which has not been cured or waived), the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent man would exercise or use under the circumstances in the conduct of his own affairs. No provision of this Indenture shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent failure to act, or its own wilful misconduct, except that: (a) this subsection shall not be construed to limit the effect of the first paragraph of this Section 7.01; (b) prior to the occurrence of an Event of Default with respect to the Debt Securities of a series and after the curing or waiving of all Events of Default with respect to such series which may have occurred: (i) the duties and obligations of the Trustee with respect to Debt Securities and Coupons, if any, of any series shall be determined solely by the express provisions of this Indenture, and the Trustee shall not be liable except for the performance of such duties and obligations with respect to such series as are specifically set forth in this Indenture, and no implied covenants or obligations with respect to such series shall be read into this Indenture against the Trustee; and (ii) in the absence of bad faith on the part of the Trustee, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon any certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture; but in the case of any such certificates or opinions which by any provision hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform to the requirements of this Indenture; but the Trustee shall examine the evidence furnished to it pursuant to Section 5.03 to determine whether or not such evidence conforms to the requirement of this Indenture; 55 62 (iii) the Trustee shall not be liable for an error of judgment made in good faith by a responsible officer, unless it shall be proved that the Trustee was negligent in ascertaining the pertinent facts; and (iv) the Trustee shall not be liable with respect to any action taken or omitted to be taken by it with respect to Debt Securities of any series in good faith in accordance with the direction of the Holders of not less than a majority in aggregate principal amount of the Outstanding Debt Securities of that series relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Indenture with respect to Debt Securities of such series. None of the provisions of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any Personal financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if there shall be reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it. Whether or not therein expressly so provided, every provision of this Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of this Section. Section 7.02. CERTAIN RIGHTS OF TRUSTEE. Except as otherwise provided in Section 7.01: (a) the Trustee may rely and shall be protected in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note or other paper or document believed by it to be genuine and to have been signed or presented by the proper party or parties; (b) any request, direction, order or demand of the Company mentioned herein shall be sufficiently evidenced by a Company Order (unless other evidence in respect thereof be herein specifically prescribed); and any resolution of the Board of Directors may be evidenced to the Trustee by a copy thereof certified by the Secretary or an Assistant Secretary of the Company; (c) the Trustee may consult with counsel, and the advice of such counsel or any Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken or suffered or omitted by it hereunder in good faith and in accordance with such advice or Opinion of Counsel; (d) the Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request, order or direction of any of the Holders of Debt Securities or Coupons of any series pursuant to the provisions of this Indenture, unless such Holders shall have offered to the Trustee reasonable security or indemnity against the costs, expenses and liabilities which may be Incurred therein or thereby; 56 63 (e) the Trustee shall not be liable for any action taken or omitted by it in good faith and reasonably believed by it to be authorized or within the discretion or rights or powers conferred upon it by this Indenture; (f) prior to the occurrence of an Event of Default and after the curing of all Events of Default which may have occurred, the Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, approval or other paper or document, unless requested in writing to do so by the Holders of a majority in aggregate principal amount of the then Outstanding Debt Securities of a series affected by such matter; provided, however, that if the payment within a reasonable time to the Trustee of the costs, expenses or liabilities likely to be Incurred by it in the making of such investigation is not, in the opinion of the Trustee, reasonably assured to the Trustee by the security afforded to it by the terms of this Indenture, the Trustee may require reasonable indemnity against such costs, expenses or liabilities as a condition to so proceeding. The reasonable expense of every such investigation shall be paid by the Company or, if paid by the Trustee, shall be repaid by the Company upon demand; (g) the Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through agents or attorneys and the Trustee shall not be responsible for any misconduct or negligence on the part of any agent or attorney appointed by it with due care hereunder; and (h) if any property other than cash shall at any time be subject to a Lien in favor of the Holders, the Trustee, if and to the extent authorized by a receivership or bankruptcy court of competent jurisdiction or by the supplemental instrument subjecting such property to such lien, shall be entitled to make advances for the purpose of preserving such property or of discharging tax Liens or other prior Liens or encumbrances thereon. Section 7.03. TRUSTEE NOT LIABLE FOR RECITALS IN INDENTURE OR IN DEBT SECURITIES. The recitals contained herein, in the Debt Securities (except the Trustee's certificate of authentication) and in any Coupons shall be taken as the statements of the Company, and the Trustee assumes no responsibility for the correctness of the same. The Trustee makes no representations as to the validity or sufficiency of this Indenture or of the Debt Securities or Coupons, if any, of any series, except that the Trustee represents that it is duly authorized to execute and deliver this Indenture, authenticate the Debt Securities and perform its obligations hereunder, and that the statements made by it or to be made by it in a Statement of Eligibility and Qualification on Form T-1 supplied to the Company are true and accurate. The Trustee shall not be accountable for the use or application by the Company of any of the Debt Securities or of the proceeds thereof. Section 7.04. TRUSTEE, PAYING AGENT OR REGISTRAR MAY OWN DEBT SECURITIES. The Trustee or any paying agent or Registrar, in its individual or any other capacity, may become the owner or pledgee of Debt Securities or Coupons and subject to the provisions of the Trust Indenture Act relating to conflicts of interest and preferential claims may otherwise deal with the Company with the same rights it would have if it were not Trustee, paying agent or Registrar. 57 64 Section 7.05. MONEYS RECEIVED BY TRUSTEE TO BE HELD IN TRUST. Subject to the provisions of Section 11.05, all moneys received by the Trustee shall, until used or applied as herein provided, be held in trust for the purposes for which they were received, but need not be segregated from other funds except to the extent required by law. The Trustee shall be under no liability for interest on any moneys received by it hereunder. So long as no Event of Default shall have occurred and be continuing, all interest allowed on any such moneys shall be paid from time to time to the Company upon a Company Order. Section 7.06. COMPENSATION AND REIMBURSEMENT. The Company covenants and agrees to pay in Dollars to the Trustee from time to time, and the Trustee shall be entitled to, reasonable compensation for all services rendered by it hereunder (which shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust), and, except as otherwise expressly provided herein, the Company will pay or reimburse in Dollars the Trustee upon its request for all reasonable expenses, disbursements and advances Incurred or made by the Trustee in accordance with any of the provisions of this Indenture (including the reasonable compensation and the expenses and disbursements of its agents, attorneys and counsel and of all Persons not regularly in its employ) except any such expense, disbursement or advances as may arise from its negligence or bad faith. The Company also covenants to indemnify in Dollars the Trustee for, and to hold it harmless against, any loss, liability or expense Incurred without negligence, wilful misconduct or bad faith on the part of the Trustee, arising out of or in connection with the acceptance or administration of this trust or trusts hereunder, including the reasonable costs and expenses of defending itself against any claim of liability in connection with the exercise or performance of any of its powers or duties hereunder. The obligations of the Company under this Section 7.06 to compensate and indemnify the Trustee and to pay or reimburse the Trustee for expenses, disbursements and advances shall constitute additional indebtedness hereunder and shall survive the satisfaction and discharge of this Indenture. The Company and the Holders agree that such additional indebtedness shall be secured by a Lien prior to that of the Debt Securities and Coupons, if any, upon all property and funds held or collected by the Trustee, as such, except funds held in trust for the payment of principal of, and premium, if any, or interest on, particular Debt Securities and Coupons. When the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.01(g) or (h) occurs, the expenses and the compensation for the services are intended to constitute expenses of administration under any bankruptcy, insolvency, reorganization or other similar law. Section 7.07. RIGHT OF TRUSTEE TO RELY ON AN OFFICERS' CERTIFICATE WHERE NO OTHER EVIDENCE SPECIFICALLY PRESCRIBED. Except as otherwise provided in Section 7.01, whenever in the administration of the provisions of this Indenture the Trustee shall deem it necessary or desirable that a matter be proved or established prior to taking or suffering or omitting any action hereunder, such matter (unless other evidence in respect thereof be herein specifically prescribed) may, in the absence of negligence or bad faith on the part of the Trustee, be deemed to be conclusively proved and established by an Officers' Certificate delivered to the Trustee and such certificate, in the absence of negligence or bad faith on the part of the Trustee, shall be full warrant to the Trustee for any action taken, suffered or omitted by it under the provisions of this Indenture upon the faith thereof. 58 65 Section 7.08. SEPARATE TRUSTEE; REPLACEMENT OF TRUSTEE. The Company may, but need not, appoint a separate Trustee for any one or more series of Debt Securities. The Trustee may resign with respect to one or more or all series of Debt Securities at any time by giving notice to the Company. The Holders of a majority in principal amount of the Debt Securities of a particular series may remove the Trustee for such series and only such series by so notifying the Trustee and may appoint a successor Trustee. The Company shall remove the Trustee if: (a) the Trustee fails to comply with Section 7.10; (b) the Trustee is adjudged bankrupt or insolvent; (c) a receiver or other public officer takes charge of the Trustee or its property; or (d) the Trustee otherwise becomes incapable of acting. If the Trustee resigns, is removed by the Company or by the Holders of a majority in principal amount of the Debt Securities of a particular series and such Holders do not reasonably promptly appoint a successor Trustee, or if a vacancy exists in the office of Trustee for any reason (the Trustee in such event being referred to herein as the retiring Trustee), the Company shall promptly appoint a successor Trustee. No resignation or removal of the Trustee and no appointment of a successor Trustee shall become effective until the acceptance of appointment by the successor Trustee in accordance with the applicable requirements of this Section 7.08. A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall mail a notice of its succession to Holders of Debt Securities of each applicable series. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, subject to the Lien provided for in Section 7.06. If a successor Trustee does not take office within 60 days after the retiring Trustee gives notice of resignation or is removed, the retiring Trustee or the Holders of 25% in principal amount of the Debt Securities of any applicable series may petition any court of competent jurisdiction for the appointment of a successor Trustee for the Debt Securities of such series. If the Trustee fails to comply with Section 7.10, any Holder of Debt Securities of any applicable series may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee for the Debt Securities of such series. Notwithstanding the replacement of the Trustee pursuant to this Section 7.08, the Company's obligations under Section 7.06 shall continue for the benefit of the retiring Trustee. In the case of the appointment hereunder of a separate or successor trustee with respect to the Debt Securities of one or more series, the Company, any retiring Trustee and each successor or 59 66 separate Trustee with respect to the Debt Securities of any applicable series shall execute and deliver an Indenture supplemental hereto (i) which shall contain such provisions as shall be deemed necessary or desirable to confirm that all the rights, powers, trusts and duties of any retiring Trustee with respect to the Debt Securities of any series as to which any such retiring Trustee is not retiring shall continue to be vested in such retiring Trustee and (ii) that shall add to or change any of the provisions of this Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one trustee, it being understood that nothing herein or in such supplemental Indenture shall constitute such Trustees co-trustees of the same trust and that each such separate, retiring or successor Trustee shall be Trustee of a trust or trusts hereunder separate and apart from any trust or trusts hereunder administered by any other such Trustee. Section 7.09. SUCCESSOR TRUSTEE BY MERGER. If the Trustee consolidates with, merges or converts into, or transfers all or substantially all its corporate trust business or assets to, another corporation or banking association, the resulting, surviving or transferee corporation or banking association without any further act shall be the successor Trustee. In case at the time such successor or successors by merger, conversion or consolidation to the Trustee shall succeed to the trusts created by this Indenture any of the Debt Securities shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor trustee, and deliver such Debt Securities so authenticated; and in case at that time any of the Debt Securities shall not have been authenticated, any successor to the Trustee may authenticate such Debt Securities either in the name of any predecessor hereunder or in the name of the successor to the Trustee; and in all such cases such certificates shall have the full force which it is anywhere in the Debt Securities or in this Indenture provided that the certificate of the Trustee shall have. Section 7.10. ELIGIBILITY; DISQUALIFICATION. The Trustee shall at all times satisfy the requirements of Section 310(a) of the Trust Indenture Act. The Trustee shall have a combined capital and surplus of at least $50,000,000 as set forth in its most recent published annual report of condition. No obligor upon the Debt Securities or Coupons, if any, of a particular series or Person directly or indirectly controlling, controlled by or under common control with such obligor shall serve as Trustee upon the Debt Securities and Coupons of such series. The Trustee shall comply with Section 310(b) of the Trust Indenture Act; provided, however, that there shall be excluded from the operation of Section 310(b)(1) of the Trust Indenture Act this Indenture or any indenture or indentures under which other securities or certificates of interest or participation in other securities of the Company are outstanding if the requirements for such exclusion set forth in Section 310(b)(1) of the Trust Indenture Act are met. Section 7.11. PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY. The Trustee shall comply with Section 311(a) of the Trust Indenture Act, excluding any creditor relationship listed in Section 311(b) of the Trust Indenture Act. A Trustee who has resigned or been removed shall be subject to Section 311(a) of the Trust Indenture Act to the extent indicated therein. Section 7.12. COMPLIANCE WITH TAX LAWS. The Trustee hereby agrees to comply with all U.S. Federal income tax information reporting and withholding requirements applicable to it with 60 67 respect to payments of premium (if any) and interest on the Debt Securities, whether acting as Trustee, Security Registrar, paying agent or otherwise with respect to the Debt Securities. ARTICLE VIII CONCERNING THE HOLDERS Section 8.01. EVIDENCE OF ACTION BY HOLDERS. Whenever in this Indenture it is provided that the Holders of a specified percentage in aggregate principal amount of the Debt Securities of any or all series may take action (including the making of any demand or request, the giving of any direction, notice, consent or waiver or the taking of any other action) the fact that at the time of taking any such action the Holders of such specified percentage have joined therein may be evidenced (a) by any instrument or any number of instruments of similar tenor executed by Holders in Person or by agent or proxy appointed in writing, (b) by the record of the Holders voting in favor thereof at any meeting of Holders duly called and held in accordance with the provisions of Section 5.02 or (c) by a combination of such instrument or instruments and any such record of such a meeting of Holders. Section 8.02. PROOF OF EXECUTION OF INSTRUMENTS AND OF HOLDING OF DEBT SECURITIES. Subject to the provisions of Sections 7.01, 7.02 and 13.11, proof of the execution of any instrument by a Holder or his agent or proxy shall be sufficient if made in accordance with such reasonable rules and regulations as may be prescribed by the Trustee or in such manner as shall be satisfactory to the Trustee. The ownership of Registered Securities of any series shall be proved by the Debt Security Register or by a certificate of the Registrar for such series. The ownership of Bearer Securities shall be proved by production of such Bearer Securities or by a certificate executed by any bank or trust company, which certificate shall be dated and shall state on the date thereof a Bearer Security bearing a specified identifying number or other mark was deposited with or exhibited to the Person executing such certificate by the Person named in such certificate, or by any other proof of possession reasonably satisfactory to the Trustee. The holding by the Person named in any such certificate of any Bearer Security specified therein shall be presumed to continue for a period of one year unless at the time of determination of such holding (a) another certificate bearing a later date issued in respect of the same Bearer Security shall be produced, (b) such Bearer Security shall be produced by some other Person, (c) such Bearer Security shall have been registered on the Debt Security Register, if, pursuant to Section 2.03, such Bearer Security can be so registered, or (d) such Bearer Security shall have been canceled or paid. The Trustee may require such additional proof of any matter referred to in this Section 8.02 as it shall deem necessary. Section 8.03. WHO MAY BE DEEMED OWNER OF DEBT SECURITIES. Prior to due presentment for registration of transfer of any Registered Security, the Company, the Trustee, any paying agent 61 68 and any Registrar may deem and treat the Person in whose name any Registered Security shall be registered upon the books of the Company as the absolute owner of such Registered Security (whether or not such Registered Security shall be overdue and notwithstanding any notation of ownership or other writing thereon) for the purpose of receiving payment of or on account of the principal of and premium, if any, and (subject to Section 2.03) interest on such Registered Security and for all other purposes, and neither the Company nor the Trustee nor any paying agent nor any Registrar shall be affected by any notice to the contrary; and all such payments so made to any such Holder for the time being, or upon his order, shall be valid and, to the extent of the sum or sums so paid, effectual to satisfy and discharge the liability for moneys payable upon any such Registered Security. The Company, the Trustee and any paying agent may deem and treat the Holder of any Bearer Security or Coupon as the absolute owner of such Bearer Security or Coupon (whether or not such Debt Security shall be overdue and notwithstanding any notation of ownership or other writing thereon) for the purpose of receiving payment of or on account of the principal of and premium, if any, and (subject to Section 2.03) interest on such Bearer Security or Coupon and for all other purposes, and neither the Company nor the Trustee nor any paying agent shall be affected by any notice to the contrary; and all such payments so made to any such Holder for the time being, or upon his order, shall be valid and, to the extent of the sum or sums so paid, effectual to satisfy and discharge the liability for moneys payable upon any such Bearer Security or Coupon. None of the Company, the Trustee, any paying agent or the Registrar will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in a Global Security or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests. Section 8.04. INSTRUMENTS EXECUTED BY HOLDERS BIND FUTURE HOLDERS. At any time prior to (but not after) the evidencing to the Trustee, as provided in Section 8.01, of the taking of any action by the Holders of the percentage in aggregate principal amount of the Debt Securities of any series specified in this Indenture in connection with such action and subject to the following paragraph, any Holder of a Debt Security which is shown by the evidence to be included in the Debt Securities the Holders of which have consented to such action may, by filing written notice with the Trustee at its corporate trust office and upon proof of holding as provided in Section 8.02, revoke such action so far as concerns such Debt Security. Except as aforesaid any such action taken by the Holder of any Debt Security shall be conclusive and binding upon such Holder and upon all future Holders and owners of such Debt Security and all past, present and future Holders of Coupons, if any, appertaining thereto, and of any Debt Security issued upon transfer thereof or in exchange or substitution therefor, irrespective of whether or not any notation in regard thereto is made upon such Debt Security or such other Debt Securities or Coupons. Any action taken by the Holders of the percentage in aggregate principal amount of the Debt Securities of any series specified in this Indenture in connection with such action shall be conclusively binding upon the Company, the Trustee and the Holders of all the Securities and Coupons of such series. The Company may, but shall not be obligated to, fix a record date for the purpose of determining the Holders of Registered Securities entitled to give their consent or take any other 62 69 action required or permitted to be taken pursuant to this Indenture. If a record date is fixed, then notwithstanding the immediately preceding paragraph, those Persons who were Holders of Registered Securities at such record date (or their duly designated proxies), and only those Persons, shall be entitled to give such consent or to revoke any consent previously given or to take any such action, whether or not such Persons continue to be Holders of Registered Securities after such record date. No such consent shall be valid or effective for more than 120 days after such record date unless the consent of the Holders of the percentage in aggregate principal amount of the Debt Securities of such series specified in this Indenture shall have been received within such 120-day period. ARTICLE IX SUPPLEMENTAL INDENTURES Section 9.01. PURPOSES FOR WHICH SUPPLEMENTAL INDENTURE MAY BE ENTERED INTO WITHOUT CONSENT OF HOLDERS. The Company, when authorized by a resolution of the Board of Directors, and the Trustee may from time to time and at any time, without the consent of Holders, enter into an Indenture or Indentures supplemental hereto (which shall conform to the provisions of the Trust Indenture Act as in force at the date of the execution thereof) for one or more of the following purposes: (a) to evidence the succession pursuant to Article X of another Person to the Company, or successive successions, and the assumption by the Successor Company (as defined in Section 10.01) of the covenants, agreements and obligations of the Company in this Indenture and in the Debt Securities; (b) to surrender any right or power herein conferred upon the Company, to add to the covenants of the Company such further covenants, restrictions, conditions or provisions for the protection of the Holders of all or any series of Debt Securities and the Coupons, if any, appertaining thereto (and if such covenants are to be for the benefit of less than all series of Debt Securities, stating that such covenants are expressly being included solely for the benefit of such series) as the Board of Directors shall consider to be for the protection of the Holders of such Debt Securities, and to make the occurrence, or the occurrence and continuance, of a Default in any of such additional covenants, restrictions, conditions or provisions a Default or an Event of Default permitting the enforcement of all or any of the several remedies provided in this Indenture; provided, that in respect of any such additional covenant, restriction, condition or provision such supplemental Indenture may provide for a particular period of grace after Default (which period may be shorter or longer than that allowed in the case of other Defaults) or may provide for an immediate enforcement upon such Default or may limit the remedies available to the Trustee upon such Default or may limit the right of the Holders of a majority in aggregate principal amount of any or all series of Debt Securities to waive such default; (c) to cure any ambiguity or to correct or supplement any provision contained herein, in any supplemental Indenture or in any Debt Securities of any series that may be defective or inconsistent with any other provision contained herein, in any supplemental Indenture or in the 63 70 Debt Securities of such series; to convey, transfer, assign, mortgage or pledge any property to or with the Trustee, or to make such other provisions in regard to matters or questions arising under this Indenture as shall not adversely affect the interests of any Holders of Debt Securities of any series; (d) to modify or amend this Indenture in such a manner as to permit the qualification of this Indenture or any Indenture supplemental hereto under the Trust Indenture Act as then in effect, except that nothing herein contained shall permit or authorize the inclusion in any Indenture supplemental hereto of the provisions referred to in Section 316(a)(2) of the Trust Indenture Act; (e) to add to or change any of the provisions of this Indenture to provide that Bearer Securities may be registerable as to principal, to change or eliminate any restrictions on the payment of principal of, or premium, if any, on, Registered Securities or of principal of, or premium, if any, or interest on, Bearer Securities or to permit Registered Securities to be exchanged for Bearer Securities; provided, that any such action shall not adversely affect the interests of the Holders of Debt Securities or any Coupons of any series in any material respect or permit or facilitate the issuance of Debt Securities of any series in uncertificated form; (f) to comply with Article X; (g) in the case of any Debt Securities and Coupons, if any, appertaining thereto subordinated pursuant to Article XII, to make any change in Article XII that would limit or terminate the benefits available to any holder of Senior Indebtedness (or Representatives therefor) under Article XII; (h) to add Guarantees with respect to the Debt Securities or to secure the Debt Securities; (i) to make any change that does not adversely affect the rights of any Holder; (j) to add to, change or eliminate any of the provisions of this Indenture in respect of one or more series of Debt Securities; provided, however, that any such addition, change or elimination not otherwise permitted under this Section 9.01 shall (i) neither (A) apply to any Debt Security of any series created prior to the execution of such supplemental indenture and entitled to the benefit of such provision nor (B) modify the rights of the Holder of any such Debt Security with respect to such provision or (ii) shall become effective only when there is no such Debt Security Outstanding; (k) to evidence and provide for the acceptance of appointment hereunder by a successor or separate Trustee with respect to the Debt Securities of one or more series and to add to or change any of the provisions of this Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one Trustee; and (l) to establish the form or terms of Debt Securities and Coupons, if any, of any series as permitted by Sections 2.01 and 2.03. 64 71 The Trustee is hereby authorized to join with the Company in the execution of any such supplemental Indenture, to make any further appropriate agreements and stipulations which may be therein contained and to accept the conveyance, transfer, assignment, mortgage or pledge of any property thereunder, but the Trustee shall not be obligated to enter into any such supplemental Indenture which affects the Trustee's own rights, duties or immunities under this Indenture or otherwise. Any supplemental Indenture authorized by the provisions of this Section 9.01 may be executed by the Company and the Trustee without the consent of the Holders of any of the Debt Securities or Coupons, if any, appertaining thereto at the time Outstanding, notwithstanding any of the provisions of Section 9.02. In the case of Debt Securities or Coupons, if any, appertaining thereto subordinated pursuant to Article XII, an amendment under this Section 9.01 may not make any change that adversely affects the rights under Article XII of any holder of Senior Indebtedness then outstanding unless the holders of such Senior Indebtedness (or any group or Representative thereof authorized to give a consent) consent to such change. After an amendment under this Section 9.01 becomes effective, the Company shall mail to Holders of Debt Securities of each series affected thereby a notice briefly describing such amendment. The failure to give such notice to all such Holders, or any defect therein, shall not impair or affect the validity of an amendment under this Section 9.01. Section 9.02. MODIFICATION OF INDENTURE WITH CONSENT OF HOLDERS OF DEBT SECURITIES. Without notice to any Holder but with the consent (evidenced as provided in Section 8.01) of the Holders of not less than a majority in aggregate principal amount of the Outstanding Debt Securities of each series affected by such supplemental Indenture, the Company, when authorized by a resolution of the Board of Directors, and the Trustee may from time to time and at any time enter into an Indenture or Indentures supplemental hereto (which shall conform to the provisions of the Trust Indenture Act as in force at the date of execution thereof) for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Indenture or of any supplemental Indenture or of modifying in any manner the rights of the Holders of the Debt Securities of such series; provided, that no such supplemental Indenture, without the consent of the Holders of each Debt Security so affected, shall (a) reduce the percentage in principal amount of Debt Securities of any series whose Holders must consent to an amendment; (b) reduce the rate of or extend the time for payment of interest on any Debt Security or Coupon or reduce the amount of any payment to be made with respect to any Coupon; (c) reduce the principal of or extend the Stated Maturity of any Debt Security; (d) reduce the premium payable upon the redemption of any Debt Security or change the time at which any Debt Security may or shall be redeemed in accordance with Article III; (e) make any Debt Security or Coupon payable in Currency other than that stated in the Debt Security; (f) in the case of any Debt Security or Coupons, if any, appertaining thereto subordinated pursuant to Article XII, make any change in Article XII that adversely affects the rights of any Holder under Article XII; (g) release any security that may have been granted in respect of the Debt Securities; (h) make any change in Section 6.06 or this Section 9.02; (i) change any obligation of the Company to pay additional interest pursuant to Section 4.06; or (j) limit the obligation of the 65 72 Company to maintain a paying agency outside the United States for payment on Bearer Securities as provided in Section 4.02 or limit the obligation of the Company to redeem a Bearer Security as provided in Section 3.02(b). A supplemental Indenture which changes or eliminates any covenant or other provision of this Indenture which has been expressly included solely for the benefit of one or more particular series of Debt Securities and Coupons, if any, or which modifies the rights of the Holders of Debt Securities and Coupons of such series with respect to such covenant or other provision, shall be deemed not to affect the rights under this Indenture of the Holders of Debt Securities and Coupons, if any, of any other series. Upon the request of the Company, accompanied by a copy of a resolution of the Board of Directors authorizing the execution of any such supplemental Indenture, and upon the filing with the Trustee of evidence of the consent of Holders as aforesaid, the Trustee shall join with the Company in the execution of such supplemental Indenture unless such supplemental Indenture affects the Trustee's own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion but shall not be obligated to enter into such supplemental Indenture. It shall not be necessary for the consent of the Holders under this Section 9.02 to approve the particular form of any proposed supplemental Indenture, but it shall be sufficient if such consent shall approve the substance thereof. In the case of any Debt Securities or Coupons, if any, appertaining thereto, subordinated pursuant to Article XII, an amendment under this Section 9.02 may not make any change that adversely affects the rights under Article XII of any holder of Senior Indebtedness then outstanding unless the holders of such Senior Indebtedness (or any group or Representative thereof authorized to give a consent) consent to such change. After an amendment under this Section 9.02 becomes effective, the Company shall mail to Holders of Debt Securities of each series affected thereby a notice briefly describing such amendment. The failure to give such notice to all such Holders, or any defect therein, shall not impair or affect the validity of an amendment under this Section 9.02. Section 9.03. EFFECT OF SUPPLEMENTAL INDENTURES. Upon the execution of any supplemental Indenture pursuant to the provisions of this Article IX, this Indenture shall be and be deemed to be modified and amended in accordance therewith and the respective rights, limitations of rights, obligations, duties and immunities under this Indenture of the Trustee, the Company and the Holders shall thereafter be determined, exercised and enforced hereunder subject in all respects to such modifications and amendments, and all the terms and conditions of any such supplemental Indenture shall be and be deemed to be part of the terms and conditions of this Indenture for any and all purposes. The Trustee, subject to the provisions of Sections 7.01 and 7.02, may receive an Officers' Certificate and an Opinion of Counsel as conclusive evidence that any such supplemental Indenture complies with the provisions of this Article IX. 66 73 Section 9.04. DEBT SECURITIES MAY BEAR NOTATION OF CHANGES BY SUPPLEMENTAL INDENTURES. Debt Securities and Coupons, if any, of any series authenticated and delivered after the execution of any supplemental Indenture pursuant to the provisions of this Article IX may, and shall if required by the Trustee, bear a notation in form approved by the Trustee as to any matter provided for in such supplemental Indenture. New Debt Securities and Coupons of any series so modified as to conform, in the opinion of the Trustee and the Board of Directors, to any modification of this Indenture contained in any such supplemental Indenture may be prepared and executed by the Company, authenticated by the Trustee and delivered in exchange for the Debt Securities and Coupons of such series then Outstanding. Failure to make the appropriate notation or to issue a new Debt Security or Coupon of such series shall not affect the validity of such amendment. Section 9.05. PAYMENT FOR CONSENT. Neither the Company nor any Affiliate of the Company shall, directly or indirectly, pay or cause to be paid any consideration, whether by way of interest, fee or otherwise, to any Holder for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of this Indenture or the Debt Securities or Coupons, if any, appertaining thereto unless such consideration is offered to be paid to all Holders that so consent, waive or agree to amend in the time frame set forth in solicitation documents relating to such consent, waiver or agreement. ARTICLE X CONSOLIDATION, MERGER, SALE OR CONVEYANCE Section 10.01. CONSOLIDATIONS AND MERGERS OF THE COMPANY. The Company shall not consolidate with or merge with or into any Person, or convey, transfer or lease all or substantially all its assets, unless: (a) either (i) the Company shall be the continuing Person in the case of a merger or (ii) the resulting, surviving or transferee Person if other than the Company (the "Successor Company") shall be a corporation organized and existing under the laws of the United States, any State thereof or the District of Columbia and the Successor Company shall expressly assume, by an Indenture supplemental hereto, executed and delivered to the Trustee, in form satisfactory to the Trustee, all the obligations of the Company under the Debt Securities and Coupons, if any, according to their tenor, and this Indenture; (b) immediately after giving effect to such transaction (and treating any Indebtedness which becomes an obligation of the Successor Company or any Subsidiary of the Company as a result of such transaction as having been Incurred by the Successor Company or such Subsidiary at the time of such transaction), no Default or Event of Default would occur or be continuing; (c) the Successor Company waives any right to redeem any Bearer Security under circumstances in which the Successor Company would be entitled to redeem such Bearer Security but the Company would not have been so entitled to redeem if the consolidation, merger, conveyance, transfer or lease had not occurred; and (d) the Company shall have delivered to the Trustee an Officers' Certificate and an Opinion of Counsel, each stating that such consolidation, merger or transfer and such supplemental Indenture (if any) comply with this Indenture. Section 10.02. RIGHTS AND DUTIES OF SUCCESSOR CORPORATION. In case of any consolidation or merger, or conveyance or transfer of the assets of the Company as an entirety or virtually as an 67 74 entirety in accordance with Section 10.01, the Successor Company shall succeed to and be substituted for the Company, with the same effect as if it had been named herein as the party of the first part, and the predecessor corporation shall be relieved of any further obligation under the Indenture and the Securities. The Successor Company thereupon may cause to be signed, and may issue either in its own name or in the name of the Company, any or all the Debt Securities issuable hereunder which theretofore shall not have been signed by the Company and delivered to the Trustee; and, upon the order of the Successor Company, instead of the Company, and subject to all the terms, conditions and limitations in this Indenture prescribed, the Trustee shall authenticate and shall deliver any Debt Securities and Coupons, if any, appertaining thereto, which previously shall have been signed and delivered by the officers of the Company to the Trustee for authentication, and any Debt Securities and Coupons, if any, appertaining thereto, which the Successor Company thereafter shall cause to be signed and delivered to the Trustee for that purpose. All the Debt Securities and Coupons, if any, appertaining thereto so issued shall in all respects have the same legal rank and benefit under this Indenture as the Debt Securities and Coupons, if any, appertaining thereto theretofore or thereafter issued in accordance with the terms of this Indenture as though all such Debt Securities and Coupons had been issued at the date of the execution hereof. In case of any such consolidation, merger, sale or conveyance such changes in phraseology and form (but not in substance) may be made in the Debt Securities and Coupons, if any, appertaining thereto thereafter to be issued as may be appropriate. ARTICLE XI SATISFACTION AND DISCHARGE OF INDENTURE; DEFEASANCE; UNCLAIMED MONEYS Section 11.01. APPLICABILITY OF ARTICLE. If, pursuant to Section 2.03, provision is made for the defeasance of Debt Securities of a series and if the Debt Securities of such series are Registered Securities and denominated and payable only in Dollars (except as provided pursuant to Section 2.03), then the provisions of this Article XI relating to defeasance of Debt Securities shall be applicable except as otherwise specified pursuant to Section 2.03 for Debt Securities of such series. Defeasance provisions, if any, for Debt Securities denominated in a Foreign Currency or for Bearer Securities may be specified pursuant to Section 2.03. Section 11.02. SATISFACTION AND DISCHARGE OF INDENTURE; DEFEASANCE. (a) If at any time (i) the Company shall have delivered to the Trustee for cancelation all Debt Securities of any series theretofore authenticated and delivered (other than (A) Coupons appertaining to Bearer Securities of such series called for redemption and maturing after the relevant redemption date, surrender of which has been waived, (B) any Debt Securities and Coupons of such series which shall have been destroyed, lost or stolen and which shall have been replaced or paid as provided in Section 2.09 and (C) Debt Securities and Coupons for whose payment money has theretofore been deposited in trust and thereafter repaid to the Company as provided in Section 11.05) or (ii) all Debt Securities and the Coupons, if any, of such series not theretofore delivered to the Trustee for cancelation shall have become due and payable, or are by their terms to become due and payable within one year or are to 68 75 be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption, and the Company shall deposit with the Trustee as trust funds the entire amount in the Currency in which such Debt Securities are denominated (except as otherwise provided pursuant to Section 2.03) sufficient to pay at maturity or upon redemption all Debt Securities of such series not theretofore delivered to the Trustee for cancelation, including principal and premium, if any, and interest due or to become due on such date of maturity or redemption date, as the case may be, and if in either case the Company shall also pay or cause to be paid all other sums payable hereunder by the Company, then this Indenture shall cease to be of further effect (except as to any surviving rights of registration of transfer or exchange of such Debt Securities herein expressly provided for and rights to receive payments of principal of, and premium, if any, and interest on, such Debt Securities and any right to receive additional interest as provided in Section 4.06) with respect to the Debt Securities of such series, and the Trustee, on demand of the Company accompanied by an Officers' Certificate and an Opinion of Counsel and at the cost and expense of the Company, shall execute proper instruments acknowledging satisfaction of and discharging this Indenture. (b) Subject to Sections 11.02(c), 11.03 and 11.07, the Company at any time may terminate, with respect to Debt Securities of a particular series, (i) all its obligations under the Debt Securities of such series and this Indenture with respect to the Debt Securities of such series ("legal defeasance option") or (ii) its obligations with respect to the Debt Securities of such series under clause (c) of Section 10.01 and the related operation of Section 6.01(d) and the operation of Sections 6.01(e), (f), (i) and (j) ("covenant defeasance option"). The Company may exercise its legal defeasance option notwithstanding its prior exercise of its covenant defeasance option. If the Company exercises its legal defeasance option, payment of the Debt Securities of the defeased series may not be accelerated because of an Event of Default. If the Company exercises its covenant defeasance option, payment of the Debt Securities of the defeased series may not be accelerated because of an Event of Default specified in Sections 6.01(d), (e), (f), (i) and (j) (except to the extent covenants or agreements referenced in such Sections remain applicable). Upon satisfaction of the conditions set forth herein and upon request of the Company, the Trustee shall acknowledge in writing the discharge of those obligations that the Company terminates. (c) Notwithstanding clauses (a) and (b) above, the Company's obligations in Sections 2.07, 2.09, 4.02, 4.04, 5.01, 7.06, 7.10, 11.05, 11.06 and 11.07 shall survive until the Debt Securities of the defeased series have been paid in full. Thereafter, the Company's obligations in Sections 7.06, 11.05 and 11.06 shall survive. Section 11.03. CONDITIONS OF DEFEASANCE. The Company may exercise its legal defeasance option or its covenant defeasance option with respect to Debt Securities of a particular series only if: (a) the Company irrevocably deposits in trust with the Trustee money or U.S. Government Obligations for the payment of principal of, and premium, if any, and interest on, the Debt Securities of such series to maturity or redemption, as the case may be; 69 76 (b) the Company delivers to the Trustee a certificate from a nationally recognized firm of independent accountants expressing their opinion that the payments of principal and interest when due and without reinvestment on the deposited U.S. Government Obligations plus any deposited money without investment will provide cash at such times and in such amounts as will be sufficient to pay the principal, premium and interest when due on all the Debt Securities of such series to maturity or redemption, as the case may be; (c) 123 days pass after the deposit is made and during the 123-day period no Default specified in Section 6.01(g) or (h) with respect to the Company occurs which is continuing at the end of the period; (d) no Default has occurred and is continuing on the date of such deposit and after giving effect thereto; (e) the deposit does not constitute a default under any other agreement binding on the Company and, if the Debt Securities of such series are subordinated pursuant to Article XII, is not prohibited by Article XII; (f) the Company delivers to the Trustee an Opinion of Counsel to the effect that the trust resulting from the deposit does not constitute, or is qualified as, a regulated investment company under the Investment Company Act of 1940; (g) in the event of the legal defeasance option, the Company shall have delivered to the Trustee an Opinion of Counsel stating that (i) the Company has received from the Internal Revenue Service a ruling, or (ii) since the date of this Indenture there has been a change in the applicable Federal income tax law, in either case of the effect that, and based thereon such Opinion of Counsel shall confirm that, the Holders of Debt Securities of such series will not recognize income, gain or loss for Federal income tax purposes as a result of such defeasance and will be subject to Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such defeasance had not occurred; (h) in the event of the covenant defeasance option, the Company shall have delivered to the Trustee an Opinion of Counsel to the effect that the Holders of Debt Securities of such series will not recognize income, gain or loss for Federal income tax purposes as a result of such covenant defeasance and will be subject to Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such covenant defeasance had not occurred; and (i) the Company delivers to the Trustee an Officers' Certificate and an Opinion of Counsel, each stating that all conditions precedent to the defeasance and discharge of the Debt Securities of such series as contemplated by this Article XI have been complied with. Before or after a deposit, the Company may make arrangements satisfactory to the Trustee for the redemption of Debt Securities of such series at a future date in accordance with Article III. 70 77 Section 11.04. APPLICATION OF TRUST MONEY. The Trustee shall hold in trust money or U.S. Government Obligations deposited with it pursuant to this Article XI. It shall apply the deposited money and the money from U.S. Government Obligations through any paying agent and in accordance with this Indenture to the payment of principal of, and premium, if any, and interest on, the Debt Securities and Coupons, if any, of the defeased series. In the event the Debt Securities and Coupons, if any, of the defeased series are subordinated pursuant to Article XII, money and securities so held in trust are not subject to Article XII. Section 11.05. REPAYMENT TO COMPANY. The Trustee and any paying agent shall promptly turn over to the Company upon request any excess money or securities held by them at any time. Subject to any applicable abandoned property law, the Trustee and any paying agent shall pay to the Company upon request any money held by them for the payment of principal, premium or interest that remains unclaimed for two years, and, thereafter, Holders entitled to such money must look to the Company for payment as general creditors. Section 11.06. INDEMNITY FOR U.S. GOVERNMENT OBLIGATIONS. The Company shall pay and shall indemnify the Trustee and the Holders against any tax, fee or other change imposed on or assessed against deposited U.S. Government Obligations or the principal and interest received on such U.S. Government Obligations. Section 11.07. REINSTATEMENT. If the Trustee or any paying agent is unable to apply any money or U.S. Government Obligations in accordance with this Article XI by reason of any legal proceeding or by reason of any order or judgment of any court or government authority enjoining, restraining or otherwise prohibiting such application, the Company's obligations under this Indenture and the Debt Securities of the defeased series shall be revived and reinstated as though no deposit had occurred pursuant to this Article XI until such time as the Trustee or any paying agent is permitted to apply all such money or U.S. Government Obligations in accordance with this Article XI. ARTICLE XII SUBORDINATION OF DEBT SECURITIES Section 12.01. APPLICABILITY OF ARTICLE; AGREEMENT TO SUBORDINATE. The provisions of this Article XII shall be applicable to the Debt Securities of any series (Debt Securities of such series referred to in this Article XII as "Subordinated Debt Securities") designated, pursuant to Section 2.03, as subordinated to Senior Indebtedness. Each Holder by accepting a Subordinated Debt Security agrees that the Indebtedness evidenced by such Subordinated Debt Security is subordinated in right of payment, to the extent and in the manner provided in this Article XII, to the prior payment of all Senior Indebtedness and that the subordination is for the benefit of and enforceable by the holders of Senior Indebtedness. All provisions of this Article XII shall be subject to Section 12.12. 71 78 Section 12.02. LIQUIDATION, DISSOLUTION, BANKRUPTCY. Upon any payment or distribution of the assets of the Company to creditors upon a total or partial liquidation or a total or partial dissolution of the Company or in a bankruptcy, reorganization, insolvency, receivership or similar proceeding relating to the Company or its property: (a) holders of Senior Indebtedness shall be entitled to receive payment in full in cash of the Senior Indebtedness (including interest (if any), accruing on or after the commencement of a proceeding in bankruptcy, whether or not allowed as a claim against the Company in such bankruptcy proceeding) before Holders of Subordinated Debt Securities shall be entitled to receive any payment of principal of, or premium, if any, or interest on, the Subordinated Debt Securities; and (b) until the Senior Indebtedness is paid in full, any distribution to which Holders of Subordinated Debt Securities would be entitled but for this Article XII shall be made to holders of Senior Indebtedness as their interests may appear, except that such Holders may receive shares of stock and any debt securities that are subordinated to Senior Indebtedness to at least the same extent as the Subordinated Debt Securities. Section 12.03. DEFAULT ON SENIOR INDEBTEDNESS. The Company may not pay the principal of, or premium, if any, or interest on, the Subordinated Debt Securities or make any deposit pursuant to Article XI and may not repurchase, redeem or otherwise retire (except, in the case of Subordinated Debt Securities that provide for a mandatory sinking fund pursuant to Section 3.05, by the delivery of Subordinated Debt Securities by the Company to the Trustee pursuant to the first paragraph of Section 3.06) any Debt Securities (collectively, "pay the Subordinated Debt Securities") if (a) any principal, premium or interest in respect of Senior Indebtedness is not paid within any applicable grace period (including at maturity) or (b) any other default on Senior Indebtedness occurs and the maturity of such Senior Indebtedness is accelerated in accordance with its terms unless, in either case, (i) the default has been cured or waived and any such acceleration has been rescinded or (ii) such Senior Indebtedness has been paid in full in cash; provided, however, that the Company may pay the Subordinated Debt Securities without regard to the foregoing if the Company and the Trustee receive written notice approving such payment from the Representative of each issue of Designated Senior Indebtedness. During the continuance of any default (other than a default described in clause (a) or (b) of the preceding sentence) with respect to any Senior Indebtedness pursuant to which the maturity thereof may be accelerated immediately without further notice (except such notice as may be required to effect such acceleration) or the expiration of any applicable grace periods, the Company may not pay the Subordinated Debt Securities for a period (a "Payment Blockage Period") commencing upon the receipt by the Company and the Trustee of written notice of such default from the Representative of any Designated Senior Indebtedness specifying an election to effect a Payment Blockage Period (a "Blockage Notice") and ending 179 days thereafter (or earlier if such Payment Blockage Period is terminated (A) by written notice to the Trustee and the Company from the Person or Persons who gave such Blockage Notice, (B) by repayment in full in cash of such Designated Senior Indebtedness or (C) because the default giving rise to such Blockage Notice is no longer continuing). Notwithstanding the provisions described in the immediately preceding sentence (but subject to the provisions contained in the first sentence of this Section 12.03), unless the holders of such Designated Senior Indebtedness or the Representative of such holders shall have accelerated the maturity of such Designated Senior Indebtedness, the Company may resume payments on the 72 79 Subordinated Debt Securities after such Payment Blockage Period. Not more than one Blockage Notice may be given in any consecutive 360-day period, irrespective of the number of defaults with respect to any number of issues of Senior Indebtedness during such period; provided, however, that if any Blockage Notice within such 360-day period is given by or on behalf of any holders of Designated Senior Indebtedness (other than the Bank Indebtedness), the Representative of the Bank Indebtedness may give another Blockage Notice within such period; provided, further, however, that in no event may the total number of days during which any Payment Blockage Period or Periods is in effect exceed 179 days in the aggregate during any 360 consecutive day period. For purposes of this Section 12.03, no default or event of default which existed or was continuing on the date of the commencement of any Payment Blockage Period with respect to the Senior Indebtedness initiating such Payment Blockage Period shall be, or be made, the basis of the commencement of a subsequent Payment Blockage Period by the Representative of such Senior Indebtedness, whether or not within a period of 360 consecutive days, unless such default or event of default shall have been cured or waived for a period of not less than 90 consecutive days. Section 12.04. ACCELERATION OF PAYMENT OF DEBT SECURITIES. If payment of the Subordinated Debt Securities is accelerated because of an Event of Default, the Company or the Trustee shall promptly notify the holders of the Designated Senior Indebtedness (or their Representatives) of the acceleration. Section 12.05. WHEN DISTRIBUTION MUST BE PAID OVER. If a distribution is made to Holders of Subordinated Debt Securities that because of this Article XII should not have been made to them, the Holders who receive such distribution shall hold it in trust for holders of Senior Indebtedness and pay it over to them as their interests may appear. Section 12.06. SUBROGATION. After all Senior Indebtedness is paid in full and until the Subordinated Debt Securities are paid in full, Holders thereof shall be subrogated to the rights of holders of Senior Indebtedness to receive distributions applicable to Senior Indebtedness. A distribution made under this Article XII to holders of Senior Indebtedness which otherwise would have been made to Holders of Subordinated Debt Securities is not, as between the Company and such Holders, a payment by the Company on Senior Indebtedness. Section 12.07. RELATIVE RIGHTS. This Article XII defines the relative rights of Holders of Subordinated Debt Securities and holders of Senior Indebtedness. Nothing in this Indenture shall: (a) impair, as between the Company and Holders of either Subordinated Debt Securities or Debt Securities, the obligation of the Company, which is absolute and unconditional, to pay principal of, and premium, if any, and interest on, the Subordinated Debt Securities and the Debt Securities in accordance with their terms; or (b) prevent the Trustee or any Holder of either Subordinated Debt Securities or Debt Securities from exercising its available remedies upon a Default, subject to the rights of holders of Senior Indebtedness to receive distributions otherwise payable to Holders of Subordinated Debt Securities. 73 80 Section 12.08. SUBORDINATION MAY NOT BE IMPAIRED BY COMPANY. No right of any holder of Senior Indebtedness to enforce the subordination of the Indebtedness evidenced by the Subordinated Debt Securities shall be impaired by any act or failure to act by the Company or by its failure to comply with this Indenture. Section 12.09. RIGHTS OF TRUSTEE AND PAYING AGENT. Notwithstanding Section 12.03, the Trustee or any paying agent may continue to make payments on Subordinated Debt Securities and shall not be charged with knowledge of the existence of facts that would prohibit the making of any such payments unless, not less than two business days prior to the date of such payment, a responsible officer of the Trustee receives notice satisfactory to it that payments may not be made under this Article XII. The Company, the Registrar, any paying agent, a Representative or a holder of Senior Indebtedness may give the notice; provided, however, that, if an issue of Senior Indebtedness has a Representative, only the Representative may give the notice. The Trustee in its individual or any other capacity may hold Senior Indebtedness with the same rights it would have if it were not Trustee. The Registrar and any paying agent may do the same with like rights. The Trustee shall be entitled to all the rights set forth in this Article XII with respect to any Senior Indebtedness which may at any time be held by it, to the same extent as any other holder of Senior Indebtedness; and nothing in Article VII shall deprive the Trustee of any of its rights as such holder. Nothing in this Article XII shall apply to claims of, or payments to, the Trustee under or pursuant to Section 7.06. Section 12.10. DISTRIBUTION OR NOTICE TO REPRESENTATIVE. Whenever a distribution is to be made or a notice given to holders of Senior Indebtedness, the distribution may be made and the notice given to their Representative (if any). Section 12.11. ARTICLE XII NOT TO PREVENT DEFAULTS OR LIMIT RIGHT TO ACCELERATE. The failure to make a payment pursuant to the Debt Securities by reason of any provision in this Article XII shall not be construed as preventing the occurrence of a Default. Nothing in this Article XII shall have any effect on the right of the Holders or the Trustee to accelerate the maturity of either the Subordinated Debt Securities or the Debt Securities, as the case may be. Section 12.12. TRUST MONEYS NOT SUBORDINATED. Notwithstanding anything contained herein to the contrary, payments from money or the proceeds of U.S. Government Obligations held in trust under Article XI by the Trustee for the payment of principal of, and premium, if any, and interest on, the Subordinated Debt Securities or the Debt Securities shall not be subordinated to the prior payment of any Senior Indebtedness or subject to the restrictions set forth in this Article XII, and none of the Holders thereof shall be obligated to pay over any such amount to the Company or any holder of Senior Indebtedness of the Company or any other creditor of the Company. Section 12.13. TRUSTEE ENTITLED TO RELY. Upon any payment or distribution pursuant to this Article XII, the Trustee and the Holders shall be entitled to rely (a) upon any order or decree of a court of competent jurisdiction in which any proceedings of the nature referred to in Section 12.02 are pending, (b) upon a certificate of the liquidating trustee or agent or other Person making such payment or distribution to the Trustee or to such Holders or (c) upon the Representatives for the 74 81 holders of Senior Indebtedness for the purpose of ascertaining the Persons entitled to participate in such payment or distribution, the holders of the Senior Indebtedness and other Indebtedness of the Company, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Article XII. In the event that the Trustee determines, in good faith, that evidence is required with respect to the right of any Person as a holder of Senior Indebtedness to participate in any payment or distribution pursuant to this Article XII, the Trustee may request such Person to furnish evidence to the reasonable satisfaction of the Trustee as to the amount of Senior Indebtedness held by such Person, the extent to which such Person is entitled to participate in such payment or distribution and other facts pertinent to the rights of such Person under this Article XII, and, if such evidence is not furnished, the Trustee may defer any payment to such Person pending judicial determination as to the right of such Person to receive such payment. The provisions of Sections 7.01 and 7.02 shall be applicable to all actions or omissions of actions by the Trustee pursuant to this Article XII. Section 12.14. TRUSTEE TO EFFECTUATE SUBORDINATION. Each Holder by accepting a Subordinated Debt Security authorizes and directs the Trustee on his behalf to take such action as may be necessary or appropriate to acknowledge or effectuate the subordination between the Holders of Subordinated Debt Securities and the holders of Senior Indebtedness as provided in this Article XII and appoints the Trustee as attorney-in-fact for any and all such purposes. Section 12.15. TRUSTEE NOT FIDUCIARY FOR HOLDERS OF SENIOR INDEBTEDNESS. The Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior Indebtedness and shall not be liable to any such holders if it shall mistakenly pay over or distribute to Holders of Subordinated Debt Securities or the Company or any other Person, money or assets to which any holders of Senior Indebtedness shall be entitled by virtue of this Article XII or otherwise. Section 12.16. RELIANCE BY HOLDERS OF SENIOR INDEBTEDNESS ON SUBORDINATION PROVISIONS. Each Holder by accepting a Subordinated Debt Security acknowledges and agrees that the foregoing subordination provisions are, and are intended to be, an inducement and a consideration to each holder of any Senior Indebtedness, whether such Senior Indebtedness was created or acquired before or after the issuance of the Subordinated Debt Securities, to acquire and continue to hold, or to continue to hold, such Senior Indebtedness and such holder of Senior Indebtedness shall be deemed conclusively to have relied on such subordination provisions in acquiring and continuing to hold, or in continuing to hold, such Senior Indebtedness. ARTICLE XIII MISCELLANEOUS PROVISIONS Section 13.01. SUCCESSORS AND ASSIGNS OF COMPANY BOUND BY INDENTURE.

Ladies and Gentlemen:
         We have acted as counsel for Pioneer Natural Resources Company, a
Delaware corporation (the "Company"), in connection with the registration under
the Securities Act of 1933 (the "Securities Act"), on a Registration Statement
on Form S-3 (No. 333- ) (the "Registration Statement") of the offer and sale
from time to time pursuant to Rule 415 under the Securities Act of the
following securities for an aggregate initial offering price not to exceed
$1,400,000,000: (i) debt securities of the Company ("Debt Securities"); (ii)
shares of preferred stock, par value $.01 per share, of the Company ("Preferred
Stock"); (iii) depositary shares representing fractional interests in Preferred
Stock ("Depositary Shares"); (iv) shares of common stock, par value $.01 per
share, of the Company ("Common Stock"); and (v) warrants to purchase Debt
Securities, Preferred Stock or Common Stock (the "Warrants", and, together with
the Debt Securities, Preferred Stock, the Depositary Shares and Common Stock,
the "Securities").
         For purposes of rendering the opinions contained in this letter, we
have reviewed those agreements, records, documents, and matters of law as we
have deemed relevant in order to render the opinions set forth herein,
including but not limited to (a) the Composite Certificate of Incorporation and

Debt Securities may be issued.
         As to certain questions of fact material to our opinions, we have
relied upon certificates from officers of the Company and other persons, as
appropriate, and upon certificates of public officials.
         Based upon and subject to the foregoing and subject further to the

such Debt Securities have been duly executed, authenticated, issued and
delivered in accordance with the provisions of the Indenture and the applicable
definitive purchase, underwriting or similar agreement approved by the Board
upon payment of the consideration therefor provided for therein, such Debt
Securities will be legally issued and will constitute valid and binding
obligations of the Company, enforceable against the Company in accordance with
their terms, except as such enforcement is subject to any applicable

creditors' rights generally and general principles of equity (regardless of
whether such enforceability is considered in a proceeding in equity or at law).
         2. With respect to shares of Preferred Stock, when both (A) the Board

the Secretary of State of the State of Delaware, and (B) certificates
representing the shares of Preferred Stock have been duly executed,
countersigned, registered and delivered either (i) in accordance with the
applicable definitive purchase, underwriting or similar agreement approved by
the Board upon payment of the consideration therefor (not less than the par
value of the Preferred Stock) provided for therein or (ii) upon conversion or
exercise of any other Security, in accordance with the terms of such Security
or the instrument governing such Security providing for such conversion or
exercise as approved by the Board, for the consideration approved by the Board
(not less than the par value of the Preferred Stock), then the shares of
Preferred Stock will be legally issued, fully paid and non assessable.

such Security or the instrument governing such Security providing for such
conversion or exercise as approved by the Board, for the consideration approved

         b. We have assumed that (i) the Registration Statement and any
amendments thereto (including post-effective amendments) will have become
effective and comply with all applicable laws; (ii) the Registration Statement

         e. We express no opinion as to the requirements of or compliance with 
federal or state securities laws or regulations.
         f. We note that the Indenture by its terms purports to be governed by
the laws of the State of New York and that the terms of the Warrants, when
determined, may be governed by the laws of a jurisdiction other than the State
of Texas or other than the General Corporation Law of the State of Delaware.
While we express no opinion with respect to the laws of the State of New York
or such other jurisdictions in rendering these opinions, we have assumed that
the internal laws of the State of New York and such other jurisdictions are the
same as the internal laws of the State of Texas. We have not conducted any
analysis to determine whether that assumption is correct.

the State of Texas, the General Corporation Law of the State of Delaware, and
the federal laws of the United States of America. You should be aware that we

         We consent to the filing of this opinion of counsel as Exhibit 5 to
the Registration Statement. We also consent to the reference to this firm under
the heading "Legal Opinions" in the Prospectus forming a part of the
Registration Statement. In giving this consent, we do not admit that this firm
is in the category of persons whose consent is required under Section 7 of the
Securities Act or the rules and regulations of the Securities and Exchange
Commission promulgated thereunder.
         We disclaim any duty to advise you regarding any changes in, or
otherwise communicate with you with respect to, the matters addressed herein.
                                                     Very truly yours,

                                                                   EXHIBIT 10.48
                        STOCK ACQUISITION LOAN AGREEMENT
     This Stock Acquisition Loan Agreement ("Agreement") is made and entered in
to as of June 15, 1995, between Parker & Parsley Petroleum Company, a Delaware 
corporation (the "Company") and Scott D. Sheffield (the "Executive").
                                   RECITALS:
     A. WHEREAS, the Board of Directors of Company (the "Board") deem it to be
in the best interest of the Company for the officers of the Company and its
Subsidiaries to accumulate and maintain significant stock ownership in the
Company;
     B. WHEREAS, Executive is an officer of Company or one of its Subsidiaries
and an employee of a Subsidiary of Company, and is desirous of accumulating
ownership of additional shares of the Company's common stock ("Shares"); and
     C. WHEREAS, the Board desires to provide Executive the means to acquire
Company's common stock;
     NOW, THEREFORE, in consideration of the foregoing and of the respective
covenants and agreements set forth below, the parties hereto agree as follows:
     1. Loan. In consideration of Executive's continued employment with any
Subsidiary of Company and other value received, Company agrees, from and after
the date hereof until the earlier to occur of (a) Executive's termination of
employment with any Subsidiary of the Company, or (b) June 22, 1995, to make
advances up to, but not in excess of $125,418 (the "Advances"), to Executive 
for the purchase of Shares. In consideration of the Advances and other value 
received, Executive promises to pay to Company the aggregate amount of all 
Advances, together with interest thereon at a rate per annum equal to 7.0625%, 
calculated on the basis of actual days elapsed, but computed as if each 
calendar year consisted of 365 or 366 days, as the case may be, as provided 
herein.
     2. Use of Advances. The Advances shall be used by Executive exclusively to
purchase Shares not later than June 22, 1995. Advances shall be made only upon
Executive's delivery to Company of written evidence satisfactory to Company of
Executive's purchase of Shares.
     3. Repayment of Loan. Advances shall be due and payable in three (3) equal
installments on each of June 15, 1996, 1997 and 1998 (each a "Payment Date"),
together with all interest then accrued but unpaid; provided, however,
Advances, together with all interest then accrued but unpaid shall be
immediately due and payable upon the termination of Executive's employment
prior to a Change in Control (as hereinafter defined) for a reason other than a
reason set forth in clause (c) of this paragraph; and provided further,
however, that amounts due under this Agreement on a Payment Date shall be
                                       1
   2
automatically forgiven by Company, without further obligation or liability
therefor by Executive, (a) in the event a Change in Control has occurred prior
to such Payment Date; (b) if Executive is then employed by Company or any
Subsidiary of Company (the "Employer"); or (c) if not employed by Employer on
such Payment Date and Executive's employment was terminated:
                  (i)      as the result of Executive's death;
                  (ii)     by Employer:
                           (A)      as a result of Executive's absence from his
                                    employment duties on a full time basis (1)
                                    for 180 consecutive calendar days due to
                                    Executive's incapacity arising from
                                    physical or mental impairment or illness;
                                    and (2) following Company's written notice
                                    of termination of employment (whether

                           Reductions), results in the Base Salary being less
                           than 65% of the highest Base Salary to which
                           Executive has ever been subject.

                           received for the actual period of existence thereof
                           exceeds the Highest Lawful Rate, the Company shall
                           refund to Executive the amount of such excess, and,
                           in such event, the Company shall not be subject to
                           any penalties provided by any law for contracting
