(c) The documents incorporated by reference in the Prospectus, when they became effective or were filed with the Commission, as the case may be, conformed in all material respects to the requirements of the Act or the Exchange Act, as applicable, and the rules and regulations of the Commission thereunder, and none of such documents contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading; and any further documents so filed and incorporated by reference in the Prospectus or any further amendment or supplement thereto, when such documents become effective or are filed with the Commission, as the case may be, will conform in all material respects to the requirements of the Act or the Exchange Act, as applicable, and the rules and regulations of the Commission thereunder and will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading; provided, however, that this representation

-2-

and warranty shall not apply to any statements or omissions made in reliance upon and in conformity with information furnished in writing to the Company by an Underwriter expressly for use therein;

(d) The Registration Statement conforms, and the Prospectus and any further amendments or supplements to the Registration Statement or the Prospectus will conform, in all material respects to the requirements of the Act and the Trust Indenture Act and the rules and regulations of the Commission thereunder and do not and will not, as of the applicable effective date as to the Registration Statement and any amendment thereto and as of the applicable filing date as to the Prospectus and any amendment or supplement thereto, contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading; provided, however, that this representation and warranty shall not apply to any statements or omissions made in reliance upon and in conformity with information furnished in writing to the Company by an Underwriter expressly for use therein;

directly or indirectly by the Company, free and clear of all liens, encumbrances, equities or claims;

(h) The Notes have been duly authorized and, when issued and delivered pursuant to this Agreement and duly executed and authenticated pursuant to the Indenture (defined below), will constitute valid and legally binding obligations of the Company entitled to the benefits provided by the Indenture dated as of August 1, 2001, between the Company and Citibank, N.A., as Trustee (the "Trustee") (the "Base Indenture" and together with the Board Resolutions and the Officer's Certificate (as defined in the Base Indenture) establishing the form and terms of the Notes pursuant to
Section 3.01 of the Base Indenture, the "Indenture"), under which they are to be issued, which Base Indenture has been filed as an exhibit to the Registration Statement; the Indenture has been duly authorized and duly qualified under the Trust Indenture Act and constitutes a valid and legally binding obligation of the Company, enforceable against the Company in accordance with its terms, subject, as to enforcement, to the effects of bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and other similar laws relating to or affecting creditors' rights generally, general equitable principles (whether considered in a proceeding in equity or at law) and an implied covenant of good faith and fair dealing; and the Indenture conforms, and the Notes will conform, to the descriptions thereof in the Prospectus;

(i) The Subsidiary Guarantees have been duly and validly authorized by the Guarantors, and, when executed and endorsed upon the Notes and delivered in accordance with the terms of the Indenture, such Subsidiary Guarantees will be valid and binding obligations of the Guarantors, enforceable against the Guarantors in accordance with their terms; the issuances of the Subsidiary Guarantees are not subject to preemptive or other similar rights to subscribe to or purchase the same arising by operation of law or under the charter, bylaws or other organizational documents of any of the Guarantors or otherwise; the form of notation to be set forth on the Notes to evidence the Subsidiary Guarantees will be in the form contemplated by the Indenture; and the Subsidiary Guarantees conform in all material respects to the description thereof contained in the Registration Statement and the Prospectus.

enforceable against the Company in accordance with their terms, subject, as to enforcement, to the effects of bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and other similar laws relating to or affecting creditors' rights generally, general equitable principles (whether considered in a proceeding in equity or at law) and an implied covenant of good faith and fair dealing, and will be entitled to the benefits of the Indenture;

(iv) The Indenture has been duly authorized, executed and delivered by the Company and duly qualified under the Trust Indenture Act and, assuming due authorization, execution and delivery thereof by the Trustee, constitutes a valid and legally binding obligation of the Company, enforceable against the Company in accordance with its terms, subject, as to enforcement, to the effects of bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and other similar laws relating to or affecting creditors' rights generally, general equitable principles (whether considered in a proceeding in equity or at law) and an implied covenant of good faith and fair dealing;

(v) The Subsidiary Guarantees have been duly authorized; executed and delivered by the Guarantors, and, assuming due authentication of the Notes by the Trustee and upon payment for and delivery of the Notes in accordance with this Agreement, will constitute valid and binding obligations of the Guarantors, enforceable against the Guarantors in accordance with their terms, except as such enforcement may be limited by bankruptcy, insolvency, reorganization, moratorium or other similar laws or judicial decisions relating to or affecting creditors' rights generally and by general equitable principles (regardless of whether such enforceability is considered in a proceeding in equity or at law).

(vi) The statements made in the Prospectus under the captions "Description of Debt Securities" and "Description of Notes," insofar as they purport to constitute summaries of certain terms of the documents referred to therein, constitute accurate summaries of the terms of such documents in all material respects; and

(vii) Neither the Company nor the Guarantors is an "investment company" within the meaning of and subject to regulation under the Investment Company Act.

In addition, such counsel shall state that they have not independently verified the accuracy, completeness or fairness of the statements made or included in the Registration Statement, the Prospectus or the Exchange Act documents incorporated therein and that they take no responsibility therefor, except as and to the extent set forth in paragraph (vi) above. Such counsel shall state that, in the course of the preparation by the Company and the Guarantors of the Registration Statement and the Prospectus (excluding the Exchange Act documents incorporated therein), such counsel participated in conferences with certain officers and employees of the Company and the Guarantors, with representatives of Arthur Andersen LLP and with counsel to the Company and the Guarantors. Such counsel may state that they did not participate in the preparation of the Exchange Act documents incorporated therein or review

-11-

such documents prior to their filing with the Commission. Such counsel shall state that, based upon such counsel's examination of the Registration Statement, Prospectus and Exchange Act documents incorporated therein and such counsel's investigations made in connection with the preparation of the Registration Statement, and the Prospectus (excluding the Exchange Act documents incorporated therein) and such counsel's participation in the conferences referred to above,
(i) such counsel is of the opinion that the Registration Statement as of its effective date, and the Prospectus, as of its date, complied as to form in all material respects with the requirements of the Act, the Trust Indenture Act and the applicable rules and regulations of the Commission thereunder and that the Exchange Act documents incorporated therein complied as to form when filed in all material respects with the requirements of the Exchange Act and the applicable rules and regulations of the Commission thereunder, except that in each case such counsel need express no opinion with respect to the financial statements or other financial data contained or incorporated by reference in the Registration Statement, the Prospectus or the Exchange Act documents incorporated therein and (ii) such counsel had no reason to believe that the Registration Statement, as of its effective date (including the Exchange Act documents incorporated therein on file with the Commission on such effective date), contained any untrue statement of a material fact or omitted to state any material fact required to be stated therein or necessary in order to make the statements therein not misleading or that the Prospectus (including the Exchange Act documents incorporated therein) as of its date contained, or, as of the Time of Delivery, contains, any untrue statement of a material fact or omitted or omits to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, except that in each case such counsel need express no belief with respect to the financial statements or other financial data contained or incorporated by reference in the Registration Statement, the Prospectus or the Exchange Act documents incorporated therein.

In rendering the foregoing opinion, Simpson Thacher & Bartlett may state that such opinion is limited to the federal laws of the United States, the laws of the State of New York and the General Corporation Law of the State of Delaware, and that they are expressing no opinion as to the effect of the laws of any other jurisdiction. In addition, such counsel may state that they have relied as to certain matters on information obtained from public officials, officers of the Company and the Guarantors and other sources believed by them to be responsible;

(d) Gregory F. Pilcher, Senior Vice President, General Counsel and Secretary of the Company, shall have furnished to you his written opinion, dated the Time of Delivery, in form and substance satisfactory to you, to the effect that:

(i) The Company has been duly qualified as a foreign corporation for the transaction of business and is in good standing under the laws of each other jurisdiction in which it owns or leases properties or conducts any business so as to require such qualification or is subject to no material liability or disability by reason of the failure to be so qualified in any such jurisdiction;

(ii) Each Significant Subsidiary of the Company (other than Kerr-McGee Operating Corporation, Kerr-McGee Rocky Mountain Corporation and Kerr-McGee Oil & Gas Corporation) has been duly incorporated or organized, as the case may be, and is validly existing in good standing under the laws of its

-12-

jurisdiction of organization; and all of the issued shares of capital stock, membership interests or partnership interests, as the case may be, of each Significant Subsidiary have been duly and validly authorized and issued, are fully paid and non-assessable, and (except for directors' qualifying shares and except as otherwise set forth in the Prospectus) are owned directly or indirectly by the Company, free and clear of all liens, encumbrances, equities or claims;

(iii) To such counsel's knowledge and other than as set forth in the Prospectus, there are no legal or governmental proceedings pending to which the Company or any of its subsidiaries is a party or of which any property of the Company or any of its subsidiaries is the subject which could reasonably be expected, either individually or in the aggregate, to have a material adverse effect on the general affairs, management, financial position, stockholders' equity or results of operations of the Company and its subsidiaries, considered as a whole; and, to such counsel's knowledge, no such proceedings are threatened or contemplated by governmental authorities or threatened by others;

(iv) The issue and sale of the Notes being issued and delivered at the Time of Delivery and the compliance by the Company and the Guarantors with all of the provisions of the Notes, the Indenture, the Subsidiary Guarantees and this Agreement and the consummation of the transactions herein and therein contemplated will not conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default under, any material indenture, mortgage, deed of trust, loan agreement or other agreement or instrument known to such counsel to which the Company or any of its Significant Subsidiaries is a party or by which the Company or any of its Significant Subsidiaries is bound or to which any of the property or assets of the Company or any of its Significant Subsidiaries is subject, nor will such actions result in any violation of the provisions of the Certificate of Incorporation or By-laws of the Company or the Guarantors or any statute or any order, rule or regulation of any court or governmental agency or body having jurisdiction over the Company or any of its Significant Subsidiaries or any of their properties; and

(v) No consent, approval, authorization, order, registration or qualification of or with any such court or governmental agency or body is required for the issue and sale of the Notes being issued and delivered at the Time of Delivery or the consummation by the Company and the Guarantors of the transactions contemplated by this Agreement, the Indenture or the Subsidiary Guarantees, except such as have been obtained under the Act and the Trust Indenture Act and such consents, approvals, authorizations, registrations or qualifications as may be required under state securities or Blue Sky laws in connection with the purchase and distribution of the Notes by the Underwriters.

(e) On the date of the Prospectus at a time prior to the execution of this Agreement, at 9:30 a.m., New York City time, on the effective date of any post-effective amendment to the Registration Statement filed subsequent to the date of this Agreement and also at such Time of Delivery, Arthur Andersen LLP and PricewaterhouseCoopers

-13-

LLP shall have furnished to you letters, dated the respective dates of delivery thereof, in form and substance satisfactory to you, to the effect set forth in Annex C and Annex D hereto, respectively;

(f) (i) Neither the Company nor any of its subsidiaries shall have sustained since the date of the latest audited financial statements included or incorporated by reference in the Prospectus any loss or interference with its business from fire, explosion, flood or other calamity, whether or not covered by insurance, or from any labor dispute or court or governmental action, order or decree, otherwise than as set forth or contemplated in the Prospectus, and

(ii) since the respective dates as of which information is given in the Prospectus there shall not have been any change in the long-term debt of the Company and its subsidiaries considered as a whole, or any change, or any development involving a prospective change, in or affecting the general affairs, management, financial position, stockholders' equity or results of operations of the Company and its subsidiaries considered as a whole, otherwise than as set forth or contemplated in the Prospectus, the effect of which, in any such case described in clause (i) or (ii), is in your judgment so material and adverse as to make it impracticable or inadvisable to proceed with the public offering or the delivery of the Notes on the terms and in the manner contemplated in the Prospectus;

(g) On or after the date hereof (i) no downgrading shall have occurred in the rating accorded the Company's debt securities by any "nationally recognized statistical rating organization," as that term is defined by the Commission for purposes of Rule 436(g)(2) under the Act, and (ii) no such organization shall have publicly announced that it has under surveillance or review, with possible negative implications, its rating of any of the Company's debt securities;

(h) On or after the date hereof there shall not have occurred any of the following: (i) a suspension or material limitation in trading in securities generally on the New York Stock Exchange; (ii) a suspension or material limitation in trading in the Company's securities on the New York Stock Exchange; (iii) a general moratorium on commercial banking activities declared by either Federal or New York State authorities; (iv) the outbreak or escalation of hostilities involving the United States or the declaration by the United States of a national emergency or war, if the effect of any such event specified in this clause (iv) in your judgment makes it impracticable or inadvisable to proceed with the public offering or the delivery of the Notes on the terms and in the manner contemplated in the Prospectus; or
(v) there shall have been such a material adverse change in general economic, political or financial conditions, or the effect of international conditions on the financial markets in the United States shall be such, as to, in your judgment make it impracticable or inadvisable to proceed with the public offering and the delivery of the Notes on the terms and in the manner contemplated in the Prospectus;

-14-

(i) The Company and the Guarantors shall have complied with the provisions of Section 5(c) hereof with respect to the furnishing of prospectuses on the New York Business Day next succeeding the date of this Agreement;

(j) The Company and the Guarantors shall have furnished or caused to be furnished to you at the Time of Delivery certificates of officers of the Company and the Guarantors satisfactory to you as to the accuracy of the representations and warranties of the Company and the Guarantors herein at and as of the Time of Delivery, as to the performance by the Company and the Guarantors of all of their obligations hereunder to be performed at or prior to the Time of Delivery, as to the matters set forth in subsections (a) and (f) of this Section and as to such other matters as you may reasonably request.

8. (a) The Company and the Guarantors, jointly and severally, will indemnify and hold harmless each Underwriter against any losses, claims, damages or liabilities, joint or several, to which such Underwriter may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, the Registration Statement, the Prospectus, any amendment or supplement thereto, or any other prospectus relating to the Notes or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse each Underwriter for any legal or other expenses reasonably incurred by such Underwriter in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that neither the Company nor the Guarantors shall be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in any Preliminary Prospectus, the Registration Statement, the Prospectus, any such amendment or supplement, or any other prospectus relating to the Notes in reliance upon and in conformity with written information furnished to the Company by any Underwriter expressly for use therein.

(b) Each Underwriter will indemnify and hold harmless the Company and the Guarantors against any losses, claims, damages or liabilities to which the Company or the Guarantors may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, the Registration Statement, the Prospectus, any amendment or supplement thereto, or any other prospectus relating to the Notes, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in any Preliminary Prospectus, the Registration Statement, the Prospectus, any such amendment or supplement, or any other prospectus relating to the Notes in reliance upon and in conformity with written information furnished to the Company by such Underwriter expressly for use therein; and will reimburse the Company and the Guarantors for any legal or other expenses

-15-

reasonably incurred by the Company and the Guarantors in connection with investigating or defending any such action or claim as such expenses are incurred.

(c) Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party otherwise than under such subsection. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and, after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such subsection for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation. No indemnifying party shall, without the written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such action or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party.

(d) If the indemnification provided for in this Section 8 is unavailable to or insufficient to hold harmless an indemnified party under subsection (a) or (b) above in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Guarantors on the one hand and the Underwriters on the other from the offering of the Notes. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law or if the indemnified party failed to give the notice required under subsection (c) above, then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company and the Guarantors on the one hand and the Underwriters on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Company and the Guarantors on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting

-16-

expenses) received by the Company bear to the total underwriting discount received by the Underwriters, in each case as set forth in the table on the cover page of the Prospectus. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company and the Guarantors on the one hand or the Underwriters on the other and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Guarantors and the Underwriters agree that it would not be just and equitable if contributions pursuant to this subsection (d) were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this subsection (d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this subsection (d), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Notes underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters' obligations in this subsection (d) to contribute are several in proportion to their respective underwriting obligations and not joint.

(e) The obligations of the Company and the Guarantors under this Section 8 shall be in addition to any liability which the Company and the Guarantors may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls any Underwriter within the meaning of the Act; and the obligations of the Underwriters under this Section 8 shall be in addition to any liability which the respective Underwriters may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of the Company and the Guarantors (including any person who, with his or her consent, is named in the Registration Statement as about to become a director of the Company) and to each person, if any, who controls the Company within the meaning of the Act.

9. (a) If any Underwriter shall default in its obligation to purchase the Notes which it has agreed to purchase hereunder at the Time of Delivery, you may in your discretion arrange for you or another party or other parties to purchase such Notes on the terms contained herein at the Time of Delivery. If within thirty-six hours after such default by any Underwriter you do not arrange for the purchase of such Notes, then the Company shall be entitled to a further period of thirty-six hours within which to procure another party or other parties satisfactory to you to purchase such Notes on such terms. In the event that, within the respective prescribed periods, you notify the Company that you have so arranged for the purchase of such Notes, or the Company notifies you that it has so arranged for the purchase of such Notes, you or the Company shall have the right to

-17-

postpone the Time of Delivery for a period of not more than seven days, in order to effect whatever changes may thereby be made necessary in the Registration Statement or the Prospectus, or in any other documents or arrangements, and the Company agrees to file promptly any amendments or supplements to the Registration Statement or the Prospectus which in your opinion may thereby be made necessary. The term "Underwriter" as used in this Agreement shall include any person substituted under this
Section with like effect as if such person had originally been a party to this Agreement with respect to the Notes.

(b) If, after giving effect to any arrangements for the purchase of the Notes of a defaulting Underwriter or Underwriters by you and the Company as provided in subsection (a) above, the aggregate principal amount of such Notes which remains unpurchased does not exceed one-eleventh of the aggregate principal amount of all the Notes, then the Company shall have the right to require each non-defaulting Underwriter to purchase the principal amount of Notes which such Underwriter agreed to purchase hereunder and, in addition, to require each non-defaulting Underwriter to purchase its pro rata share (based on the principal amount of Notes which such Underwriter agreed to purchase hereunder at the Time of Delivery) of the Notes of such defaulting Underwriter or Underwriters for which such arrangements have not been made; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

(c) If, after giving effect to any arrangements for the purchase of the Notes of a defaulting Underwriter or Underwriters by you and the Company as provided in subsection (a) above, the aggregate principal amount of Notes which remains unpurchased exceeds one-eleventh of the aggregate principal amount of all the Notes to be purchased at such Time of Delivery, or if the Company shall not exercise the right described in subsection (b) above to require non-defaulting Underwriters to purchase Notes of a defaulting Underwriter or Underwriters, then this Agreement shall thereupon terminate, without liability on the part of any non-defaulting Underwriter or the Company, except for the expenses to be borne by the Company and the Underwriters as provided in Section 6 hereof and the indemnity and contribution agreements in Section 8 hereof; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

10. The respective indemnities, agreements, representations, warranties and other statements of the Company, the Guarantors and the several Underwriters, as set forth in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall remain in full force and effect, regardless of any investigation (or any statement as to the results thereof) made by or on behalf of any Underwriter or any controlling person of any Underwriter, or the Company, or any officer or director or controlling person of the Company, or the Guarantors, or any officer or director or controlling person of the Guarantors, and shall survive delivery of and payment for the Notes.

11. If this Agreement shall be terminated pursuant to Section 9 hereof, the Company and the Guarantors shall not then be under any liability to any Underwriter except as provided in Sections 6 and 8 hereof; but, if for any other reason, any Notes or the Subsidiary Guarantee are not delivered by or on behalf of the Company or the Guarantors, as applicable, as provided

-18-

herein, the Company and the Guarantors will reimburse the Underwriters for all out-of-pocket expenses approved in writing by you, including fees and disbursements of counsel, reasonably incurred by the Underwriters in making preparations for the purchase, sale and delivery of the Notes, but the Company and the Guarantors shall then be under no further liability to any Underwriter except as provided in Sections 6 and 8 hereof.

12. All statements, requests, notices and agreements hereunder shall be in writing, and if to the Underwriters shall be delivered or sent by mail or facsimile transmission to you c/o Lehman Brothers, Inc., 101 Hudson Street, Jersey City, New Jersey 07302, Attention: Fixed Income Syndicate (with a copy to the General Counsel); and if to the Company or the Guarantors shall be delivered or sent by mail or facsimile transmission to the address of the Company set forth in the Registration Statement, Attention: General Counsel; provided, however, that any notice to an Underwriter pursuant to Section 8(c) hereof shall be delivered or sent by mail or facsimile transmission to such Underwriter at its address set forth in its Underwriters' Questionnaire, or telex constituting such Questionnaire, which address will be supplied to the Company by you upon request. Any such statements, requests, notices or agreements shall take effect upon receipt thereof.

13. This Agreement shall be binding upon, and inure solely to the benefit of, the Underwriters, the Company, the Guarantors and, to the extent provided in Sections 8 and 10 hereof, the officers and directors of the Company and the Guarantors and each person who controls the Company or the Guarantors or any Underwriter, and their respective heirs, executors, administrators, successors and assigns, and no other person shall acquire or have any right under or by virtue of this Agreement. No purchaser of any of the Notes from any Underwriter shall be deemed a successor or assign by reason merely of such purchase.

14. Time shall be of the essence of this Agreement. As used herein, the term "business day" shall mean any day when the Commission's office in Washington, D.C. is open for business.

15. This Agreement shall be governed by and construed in accordance with the laws of the State of New York.

16. This Agreement may be executed by any one or more of the parties hereto in any number of counterparts, each of which shall be deemed to be an original, but all such respective counterparts shall together constitute one and the same instrument.

-19-

If the foregoing is in accordance with your understanding, please sign and return to us one for the Company, one for each of you, and one for each counsel counterparts hereof, and upon the acceptance hereof by each of you, this letter and such acceptance hereof shall constitute a binding agreement between each of the Underwriters and the Company.

Very truly yours,

MATTERS TO BE ADDRESSED IN COMFORT LETTERS OF ARTHUR ANDERSEN LLP

Arthur Andersen LLP shall furnish letters to the Underwriters, dated the respective date of delivery thereof, in form and substance satisfactory to the Underwriters, confirming that they are independent certified public accountants with respect to the Company and its subsidiaries within the meaning of the Act and the Exchange Act and the respective applicable rules and regulations adopted by the Commission thereunder and that they have performed a review of the unaudited interim financial information of the Company for the three-month and six-month periods ended June 30, 2001, and as at June 30, 2001, in accordance with the Statement on Auditing Standards No. 71, and stating in effect that:

(i) in their opinion the audited financial statements and financial statement schedules included or incorporated in the Registration Statement and the Prospectus and reported on by them comply in form in all material respects with the applicable accounting requirements of the Act and the Exchange Act and the related rules and regulations adopted by the Commission;

(ii) on the basis of a reading of the latest unaudited financial statements made available by the Company and its subsidiaries; their limited review, in accordance with standards established under Statement on Auditing Standards No. 71, of the unaudited interim financial information for the three-month and six-month periods ended June 30, 2001, and as at June 30, 2001; carrying out certain specified procedures (but not an examination in accordance with generally accepted auditing standards) which would not necessarily reveal matters of significance with respect to the comments set forth in such letter; a reading of the minutes of the meetings of the directors and audit committee of the Company and its subsidiaries; and inquiries of certain officials of the Company who have responsibility for financial and accounting matters of the Company and its subsidiaries as to transactions and events subsequent to December 31, 2000, nothing came to their attention which caused them to believe that:

(3) the information included or incorporated by reference in the Registration Statement and the Prospectus in response to Regulation S-K, Item 301 (Selected Financial Data), Item 302 (Supplementary Financial Information) and Item
503(d) (Ratio of Earnings to Fixed Charges) is in conformity with the applicable disclosure requirements of Regulation S-K.

(iii) they have performed certain other specified procedures as a result of which they determined that certain information of an accounting, financial or statistical nature (which is limited to accounting, financial or statistical information derived from the general accounting records of the Company and its subsidiaries) set forth in the Registration Statement and the Prospectus and in Exhibit 12 to the Registration Statement, including the information set forth under the captions "Selected Financial and Operating Data of Kerr-McGee" in the Prospectus and "Ratio of Earnings to Fixed Charges and Ratio of Earnings to Combined Fixed Charges and Preferred Stock Dividend Requirements" in the Prospectus, the information included or incorporated by reference in Items 1, 2, 6 and 7 of the Company's Annual Report on Form 10-K and the Company's Quarterly Reports on Form 10-Q, incorporated by reference in the Registration Statement and the Prospectus, agrees with the accounting records of the Company and its subsidiaries, excluding any questions of legal interpretation.

In any case where notice to Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders. Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver.

The Trustee shall have the right to decline to authenticate and deliver any Securities under this Section if the Trustee, being advised by counsel, determines that such action may not lawfully be taken or if the Trustee in good faith shall determine that such action would expose the Trustee to personal liability to existing Holders.

Each Security shall be dated the date of its authentication.

SECTION 3.04. Execution of Securities. The Securities shall be signed in the name and on behalf of the Company by the manual or facsimile signatures of the Chairman of the Board or its Vice Chairman or its President or one of its Vice Presidents under its corporate seal (which may be printed, engraved or otherwise reproduced thereon, by facsimile or otherwise), and attested by its Treasurer or Secretary or one of its Assistant Treasurers or Assistant Secretaries. Only such Securities as shall bear thereon a certificate of authentication substantially in the form hereinbefore recited, executed 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 Security executed by the Company shall be conclusive evidence that the Security so authenticated has been duly authenticated and delivered hereunder and that the Holder is entitled to the benefits of this Indenture.

In case any officer of the Company who shall have signed any of the Securities shall cease to be such officer before the Securities so signed shall have been authenticated and delivered by the Trustee, or disposed of by the Company, such Securities nevertheless may be authenticated and delivered or disposed of as though the person who signed such Securities had not ceased to be such officer of the Company; and any Security may be signed on behalf of the company by such persons as, at the actual date of the execution of such Security, shall be the proper officers of the Company, although at the date of the execution of this Indenture any such person was not such an officer.

SECTION 3.05. Exchange and Registration of Transfer of Securities. Securities of any series may be exchanged for a like aggregate principal amount of Securities of the same series of other authorized denominations. Securities to be exchanged shall be surrendered at the office or agency to be maintained by the Company in the Borough of Manhattan, The City of New York, as provided in
Section 10.02. The Trustee is hereby appointed "Security Registrar" for the purpose of the registration of Securities and of transfer of Securities in the Security Register as herein provided. The Company shall cause to be kept at the Corporate Trust Office of the Trustee a register for each series of Securities issued hereunder (hereinafter collectively referred to as the "Security Register") in which, subject to such reasonable regulations at it may prescribe, the Company shall provide for the registration of Securities and the transfer of Securities as in this Article Three provided. The Security Register shall be in written form or in any other form capable of being converted into written form within a reasonable time. Upon due presentment for registration of transfer of any Security of any series at such office or agency, the Company shall execute and the Trustee shall register, authenticate and deliver in the name of the transferee or transferees a new Security or Securities of the same series for an equal aggregate principal amount.


16

All Securities presented for registration of transfer or for exchange, redemption or payment shall (if so required by the Company or the Security Registrar) be duly endorsed by, or be accompanied by a written instrument or instruments of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the registered Holder or his attorney duly authorized in writing.

No service charge shall be made for any exchange or registration of transfer of Securities, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection therewith.

The Company shall not be required to exchange or register the transfer of (a) any Securities of any series for a period of 15 days next preceding any selection of Securities of that series to be redeemed, or (b) any Securities selected, called or being called for redemption except, in the case of any Security to be redeemed in part, the portion thereof not so to be redeemed.

SECTION 3.06. Mutilated, Destroyed, Lost or Stolen Securities. In case any temporary or definitive Security shall become mutilated or be destroyed, lost or stolen, the Company in the case of a mutilated Security shall, and in the case of a lost, stolen or destroyed Security may in its discretion, execute, and upon its request the Trustee shall authenticate and deliver, a new Security of the same series bearing a number, letter or other distinguished symbol not contemporaneously outstanding, in exchange and substitution for the mutilated Security, or in lieu of and in substitution for the Security so destroyed, lost or stolen, or if any such Security shall have matured or shall be about to mature, instead of issuing a substituted Security, the Company may pay or authorize the payment of the same without surrender thereof (except in the case of a mutilated Security). In every case the applicant for a substituted Security shall furnish to the Company and to the Trustee such security or indemnity as may be required by them to save each of them harmless, and, in every case of destruction, loss or theft, the applicant shall also furnish to the Company and to the Trustee evidence to their satisfaction of the destruction, loss or theft of such Security and of the ownership thereof.

The Trustee may authenticate any such substituted Security and deliver the same upon the written request or authorization of any officer of the Company. Upon the issuance of any substituted 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 and in addition a further sum not exceeding two dollars for each Security so issued in substitution.

Every substituted Security issued pursuant to the provisions of this
Section 3.06 by virtue of the fact that any Security is destroyed, lost or stolen shall constitute an additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Security 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 Securities of that series duly issued hereunder. All Securities 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 Securities and shall preclude (to the extent lawful) any and all other rights or remedies with respect to the replacement or payment of negotiable instruments or other securities without their surrender.


17

SECTION 3.07. Temporary Securities. Pending the preparation of definitive Securities of any series the Company may execute and the Trustee shall authenticate and deliver temporary Securities (printed or lithographed). Temporary Securities shall be issuable in any authorized denomination and substantially in the form of the definitive Securities but with such omissions, insertions and variations as may be appropriate for temporary Securities, all as may be determined by the Company. Every such temporary Security shall be executed by the Company and shall be authenticated by the Trustee upon the same conditions and in substantially the same manner, and with the same effect, as the definitive Securities. Without unreasonable delay the Company will execute and deliver to the Trustee definitive Securities of such series and thereupon any or all temporary Securities of such series may be surrendered in exchange therefore, at the Corporate Trust Office of the Trustee, and the Trustee shall authenticate and deliver in exchange for such temporary Securities an equal aggregate principal amount of definitive Securities. Such exchange shall be made by the Company at its own expense and without any charge therefor except that in case of any such exchange involving any registration of transfer the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto. Until so exchanged, the temporary Securities shall in all respects be entitled to the same benefits under this Indenture as definitive Securities authenticated and delivered hereunder.

If the Company shall establish pursuant to Section 3.01 that the Securities of a 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 shall, in accordance with Section 3.03 and the Company Order with respect to such series, authenticate and deliver one or more Global Securities in temporary or permanent form that (i) shall represent and shall be denominated in an amount equal to the aggregate principal amount of the Outstanding Securities of such series to be represented by one or more Global Securities, (ii) shall be registered in the name of the U.S. Depositary for such Global Security or Securities or the nominee of such depositary, and (iii) shall bear a legend substantially to the following effect: "This 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, unless and until this Security is exchanged in whole or in part for Securities in definitive form" and such other legend as may be required by the U.S. Depositary.

Notwithstanding any other provision of this Section or Section 3.07, unless and until it is exchanged in whole or in part for Securities in definitive form, a Global Security representing all or a portion of the Securities of a series may not be transferred except as a whole by the U.S. Depositary for such series to a nominee of such depositary or by a nominee of such depositary to such depositary or another nominee of such depositary or by such depositary or any such nominee to a successor U.S. Depositary for such series or a nominee of such successor depositary.

If at any time the U.S. Depositary for the Securities of a series notifies the Company that it is unwilling or unable to continue as U.S. Depositary for the Securities of such series or if at any time the U.S. Depositary for Securities of a series shall no longer be a clearing agency registered and in good standing under the Securities Exchange Act of 1934, as amended, or other applicable statute or regulation, the Company shall appoint a successor U.S. Depositary with respect to the Securities of such


18

series. If a successor U.S. Depositary for the Securities of such series is not appointed by the Company within 90 days after the Company receives such notice or becomes aware of such condition, the Company will execute, and the Trustee, upon receipt of a Company Order for the authentication and delivery of definitive Securities of such series, will authenticate and deliver, Securities of such series in definitive form in an aggregate principal amount equal to the principal amount of the Global Security or Securities representing such series in exchange for such Global Security or Securities.

The Company may at any time and in its sole discretion determine that the Securities of any series issued 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 definitive Securities of such series, will authenticate and deliver, Securities of such series in definitive form and in an aggregate principal amount equal to the principal amount of the Global Security or Securities representing such series in exchange for such Global Security or Securities.

If the Securities of any series shall have been issued in the form of one or more Global Securities and if an Event of Default with respect to the Securities of such series shall have occurred and be continuing, the Company will promptly execute, and the Trustee, upon receipt of a Company Order for the authentication and delivery of definitive Securities of such series, will authenticate and deliver Securities of such series in definitive form and in an aggregate principal amount equal to the principal amount of the Global Security or Securities representing such series in exchange for such Global Security or Securities.

If specified by the Company pursuant to Section 3.01 with respect to Securities of a series, the U.S. Depositary for such series of Securities may surrender a Global Security for such series of Securities in exchange in whole or in part for Securities of such series in definitive form on such terms as are acceptable to the Company and such depositary. Thereupon, the Company shall execute and the Trustee shall authenticate and deliver, without charge:

(1) to each Person specified by the U.S. Depositary a new Registered Security or Securities of the same series, of any authorized denomination as requested by such Person in an aggregate principal amount equal to and in exchange for such Person's beneficial interest in the Global Security; and

(2) to the U.S. Depositary a new Global Security in a denomination equal to the difference, if any, between the principal amount of the surrendered Global Security and the aggregate principal amount of Securities delivered to Holders thereof.

Upon the exchange of a Global Security in whole for Securities in definitive form, such Global Security shall be cancelled by the Trustee. Securities so issued in exchange for a Global Security shall be registered in such names and in such authorized denominations as the U.S. Depositary for such Global Security, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee. The Trustee shall deliver such Securities to the Persons in whose names such Securities are so registered.

SECTION 3.08. Payment of Interest; Interest Rights Preserved. Interest on any Security which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall


19

be paid to the Person in whose name that Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest.

Any interest on any Security which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date or within 30 days thereafter (herein called "Defaulted Interest") shall forthwith cease to be payable to the registered Holder on the relevant Regular Record Date by virtue of having been such Holder; and such Defaulted Interest may be paid by the Company, at its election in each case, as provided in clause (1) or (2) below:

(1) The Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Securities (or their respective Predecessor Securities) 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 Security 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 Date therefor to be mailed, first-class postage prepaid, to each Holder at his address as it appears in the Security Register not less than 10 days prior to such Special Record Date. The Trustee may, in its discretion, in the name and at the expense of the Company, cause a similar notice to be published at least once in a newspaper, customarily published in the English language on each Business Day and of general circulation in the Borough of Manhattan, The City of New York, but such publication shall not be a condition precedent to the establishment of such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been mailed as aforesaid, such Defaulted Interest shall be paid to the Persons in whose names the Securities (or their respective Predecessor Securities) are registered on such Special Record Date and shall no longer be payable pursuant to the following clause (2).

(2) The Company may make payment of any Defaulted Interest in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Securities 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.

Subject to the foregoing provisions of this Section, each Security delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Security shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Security.


20

SECTION 3.09. Persons Deemed Owners. Prior to due presentment of a Security for registration of transfer, the Company, the Trustee, the Authenticating Agent and any agent of the Company or the Trustee may treat the Person in whose name the Security is registered as the owner of such Security for the purpose of receiving payment of principal of, and (subject to Section 3.08) interest on, such Security and for all other purposes whatsoever, whether or not such Security be overdue, and neither the Company, the Trustee, the Authenticating Agent nor any agent of the Company or the Trustee shall be affected by notice to the contrary.

SECTION 3.10. Cancellation. All Securities surrendered for payment, redemption, registration of transfer or exchange shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee, and any such Securities and Securities surrendered directly to the Trustee for any such purpose shall be promptly cancelled by it. The Company may at any time deliver to the Trustee for cancellation any Securities previously authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever, and all Securities so delivered shall be promptly cancelled by the Trustee. No Securities shall be authenticated in lieu of or in exchange for any Securities cancelled as provided in this Section, except as expressly permitted by this Indenture. All cancelled Securities held by the Trustee shall be disposed of by the Trustee in its customary manner.

SECTION 3.11. Computation of Interest. Except as otherwise specified as contemplated by Section 3.01 for Securities of any Series, interest on the Securities of each series shall be computed on the basis of a 360-day year of twelve 30-day months.

SECTION 3.12. CUSIP Numbers. The Company in issuing the Securities may use "CUSIP" numbers (if then generally in use), and, if so, the Trustee shall use "CUSIP" numbers in notices of redemption as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Securities or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Securities, and any such redemption shall not be affected by any defect in or omission of such numbers. The Company will promptly notify the Trustee of any change in the "CUSIP" numbers.

ARTICLE FOUR

SECTION 4.01. Satisfaction and Discharge of Indenture. This Indenture shall cease to be of further effect (except as to any surviving rights of registration of transfer or exchange of Securities herein expressly provided for), and the Trustee, on demand of and at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture, when

(1) either

21

replaced or paid as provided in Section 3.06 and (ii) Securities for whose payment money has theretofore been deposited in trust or segregated and held in trust by the Company and thereafter repaid to the Company or discharged from such trust, as provided in Section 10.03) have been delivered to the Trustee for cancellation; or

(2) the Company has paid or caused to be paid all other sums payable hereunder by the Company; and

(3) the Company has delivered to the Trustee an Officers' Certificate and an Opinion of Counsel each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture have been complied with.

SECTION 4.02. Application of Trust Money. All money deposited with the Trustee pursuant to Section 4.01 shall be held in trust and applied by it, in accordance with the provisions of the Securities and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal (and premium, if any) and interest for whose payment such money has been deposited with the Trustee; but such money need not be segregated from other funds except to the extent required by law.

If an Event of Default described in clauses (a), (b), (c) or (g) or established pursuant to Section 3.01 with respect to Securities of any series at the time Outstanding occurs and is continuing, then and in each and every such case, unless the principal of all the Securities of such series shall have already become due and payable, either the Trustee or the Holders of not less than 25 percent in aggregate principal amount of the Securities of such series then Outstanding hereunder, by notice in writing to the Company (and to the Trustee if given by Holders), may declare the principal amount (or, if the Securities of that series are Original Issue Discount Securities, such portion of the principal amount as may be specified in the terms of that series) of all the Securities of such series to be due and payable immediately, and upon any such declaration the same shall become and shall be immediately due and payable, anything in this Indenture or in the Securities of such series contained to the contrary notwithstanding.

The foregoing provisions are, however, subject to the condition that if, at any time after the principal amount (or, if the Securities of that series are Original Issue Discount Securities, such portion of the principal amounts as may be specified in the terms of that series) of the Securities of any series (or of all the Securities, as the case may be) shall have been so declared due and payable, and before any judgment or decree for the payment of the moneys due shall have been obtained or entered as hereinafter provided, the Company shall pay or shall deposit with the Trustee a sum sufficient to pay all matured installments of interest upon


24

all the Securities of such series (or of all the Securities, as the case may be) and the principal of and premium, if any, on any and all Securities of such series (or of all the Securities, as the case may be) which shall have become due otherwise than by acceleration (with interest on overdue installments of interest, to the extent that payment of such interest is enforceable under applicable law, and on such principal and premium, if any, at the rate of interest or Yield to Maturity (in the case of Original Issue Discount Securities) borne by the Securities of such series (or at the rates of interest or Yields to Maturity of all the Securities, as the case may be), to the date of such payment or deposit) and the reasonable expenses of the Trustee, and any and all defaults under this Indenture, other than the nonpayment of principal of or premium, if any, or accrued interest on Securities of such series (or of all the Securities, as the case may be) which shall have become due by acceleration, shall have been cured or waived pursuant to Section 5.08 -- then and in every such case the Holders of a majority in aggregate principal amount of the Securities of such series (or of all the Securities, as the case may be) then Outstanding, by written notice to the Company and to the Trustee, may waive all defaults with respect to that series (or with respect to all Securities, as the case may be) and rescind and annul such declaration and its consequences; but no such waiver or rescission and annulment shall extend to or shall affect any subsequent default, or shall impair any right consequent thereon.

In case the Trustee or any Holder shall have proceeded to enforce any right under this Indenture and such proceedings shall have been discontinued or abandoned because of such rescission or annulment or for any other reason or shall have been determined adversely to the Trustee or to such Holder, then and in every such case the Company and the Trustee and the Holders shall be restored respectively to their several positions and rights hereunder, and all rights, remedies and powers of the Company and the Trustee and the Holders shall continue as though no such proceeding had been taken.

SECTION 5.03. Payment of Securities on Default; Suit Therefor.

The Company covenants that (a) in case default shall be made in the payment of any installment of interest upon any of the Securities of any series as and when the same shall become due and payable, and such default shall have continued for a period of 30 days, or (b) in case default shall be made in the payment of the principal of and premium, if any, on any of the Securities of any series as and when the same shall become due and payable, whether at maturity of the Securities of that series or upon redemption or by declaration, repayment or otherwise -- then, upon demand of the Trustee, the Company will pay to the Trustee, for the benefit of the Holders of the Securities of that series, the whole amount that then shall have become due and payable on all such Securities of that series for principal and premium, if any, or interest, or both, as the case may be, with interest upon the overdue principal and (to the extent that payment of such interest is enforceable under applicable law) upon the overdue installments of interest at the rate or Yield to Maturity (in the case of Original Issue Discount Securities) borne by the Securities of that series; and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including reasonable compensation to the Trustee, its agents, attorneys and counsel, and any expenses or liabilities incurred by the Trustee hereunder other than through its negligence or bad faith.

In case the Company shall fail to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, shall be entitled and empowered to institute any actions or proceedings at law or in equity for the collection of the sums so due and


25

unpaid, and may prosecute any such action or proceeding to judgment or final decree, and may enforce any such judgment or final decree against the Company or any other obligor upon such Securities and collect in the manner provided by law out of the property of the Company or any other obligor upon such Securities wherever situated the moneys adjudged or decreed to be payable.

In case there shall be pending proceedings for the bankruptcy or for the reorganization of the Company or any other obligor on the Securities of any series under any applicable bankruptcy, insolvency or similar law, or in case a receiver or trustee shall have been appointed for the property of the Company or such other obligor, or in the case of any other similar judicial proceedings relative to the Company or other obligor upon the Securities of any series, or to the creditors or property of the Company or such other obligor, the Trustee, irrespective of whether the principal of the Securities 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 5.03 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 (and premium, if any) and interest (or, if the Securities of that series are Original Issue Discount Securities, such portion of the principal amount as may be specified in the terms of that series) owing and unpaid in respect of the Securities of any series and, in case of any judicial proceedings, to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee and of the Holders allowed in such judicial proceedings relative to the Company or any other obligor on the Securities of any series, its or their creditors, or its or their property, and to collect and receive any moneys or other property payable or deliverable on any such claims, and to distribute the same after the deduction of its charges and expenses; and any receiver, assignee or trustee in bankruptcy or reorganization is hereby authorized by each of the Holders to make such payments to the Trustee, and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for compensation and expenses, including counsel fees incurred by it up to the date of such distribution. To the extent that such payment of reasonable compensation, expenses and counsel fees out of the estate in any such proceedings shall be denied for any reason, payment of the same shall be secured by a lien on, and shall be paid out of, any and all distributions, dividends, moneys, securities and other property which the Holders of the Securities of any series may be entitled to receive in such proceedings, whether in liquidation or under any plan of reorganization or arrangement or otherwise.

All rights of action and of asserting claims under this Indenture, or under any of the Securities, may be enforced by the Trustee without the possession of any of the Securities, or the production thereof on any trial or other proceeding relative thereto, and any such suit or proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall be for the ratable benefit of the Holders of all the Securities in respect of which such action was taken.

SECTION 5.04. Application of Moneys Collected by Trustee. Any moneys collected by the Trustee under this Article Five shall be applied in the order following, at the date or dates fixed by the Trustee for the distribution of such moneys, upon presentation of the several Securities in respect of which moneys have been collected, and stamping thereon the payment, if only partially paid, and upon surrender thereof if fully paid:


26

SECTION 5.05. Proceedings by Holders. No Holder of any Security of any series shall have any right by virtue of or by availing of any provision of this Indenture to institute any suit, action or proceeding in equity or at law 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 default and of the continuance thereof, as hereinbefore provided, and unless also the Holders of not less than 25 percent in aggregate principal amount of the Securities of that series then Outstanding, or, in the case of any Event of Default in respect of the Company described in clause (d), (e) or (f) of Section 5.01, 25 percent in aggregate principal amount of all Securities then Outstanding, or, in the case of any Event of Default in respect of a Guarantor described in clause (d), (e) or (f) of Section 5.01, 25 percent in aggregate principal amount of all Securities guaranteed hereunder by such Guarantor then Outstanding, shall have made written request upon the Trustee to institute such action, suit or proceeding 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 neglected or refused to institute any such action, suit or proceeding, it being understood and intended, and being expressly covenanted by the taker and Holder of every Security with every other taker and Holder and the Trustee, that no one or more Holders shall


27

have any right in any manner whatever by virtue of or by availing of any provision of this Indenture to affect, disturb or prejudice the rights of any other Holder, 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.

Notwithstanding any other provisions in this Indenture, however, the right of any Holder of any Security to receive payment of the principal of and premium, if any, and interest on such Security, on or after the respective due dates expressed in such Security, or to institute suit for the enforcement of any such payment on or after such respective dates shall not be impaired or affected without the written consent of such Holder.

SECTION 5.06. Proceedings by Trustee. 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 Trustee shall deem necessary to protect and enforce any of such rights, either by suit in equity or by action at law or by proceeding 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.

SECTION 5.07. Remedies Cumulative and Continuing. All powers and remedies given by this Article Five 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 5.05, every power and remedy given by this Article Five 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 5.08. Direction of Proceedings and Waiver of Defaults by Majority of Holders. The Holders of a majority in aggregate principal amount of the Securities of all 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 exercising any trust or power conferred on the Trustee with respect to the Securities of such series; provided, however, that (subject to the provisions of Section 6.01) the Trustee shall have the right to decline to follow any such direction if the Trustee, being advised by counsel, determines that the action or proceeding so directed may not lawfully be taken or if the Trustee in good faith shall determine that the action or proceedings so directed would involve the Trustee in personal liability. Subject to Section 5.02, the Holders of a majority in aggregate principal amount of the Securities of that series at the time Outstanding may on behalf of the Holders of all of the Securities of that series waive any past default or Event of Default described in clauses (a), (b), (c) or (g) of Section 5.01, or any other Event of Default for such series specified in the terms thereof as contemplated by
Section 3.01 (or, in the case of an event in respect of the Company specified in clause (d), (e) or (f) of Section 5.01, the Holders of a majority in aggregate principal amount of all the Securities then Outstanding may waive any such default or Event of Default, or, in the case of an event in


28

respect of a Guarantor specified in clause (d), (e) or (f) of Section 5.01, the Holders of a majority in aggregate principal amount of all the Securities guaranteed hereunder by such Guarantor then Outstanding may waive any such default or Event of Default), and its consequences except a default in the payment of interest, or premium, if any, on, or the principal of any of the Securities. Upon any such waiver the Company, the Trustee and the Holders of the Securities of that series (or of all of the Securities, as the case may be) shall be restored to their former positions and rights hereunder, respectively; but no such waiver shall extend to any subsequent or other default or Event of Default or impair any right consequent thereon. Whenever any default or Event of Default hereunder shall have been waived as permitted by this Section 5.08, said default or Event of Default shall for all purposes of the Securities of that series and this Indenture be deemed to have been cured and to be not continuing.

SECTION 5.09. Undertaking to Pay Costs. All parties to this Indenture agree, and each Holder of any Security 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, and that such court may in its discretion assess reasonable costs, including reasonable attorneys' fees and expenses, 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 5.09 shall not apply to any suit instituted by the Trustee, to any suit instituted by any Holder of the Securities of any series or group of such Holders, holding in the aggregate more than ten percent in principal amount of the Outstanding Securities of that series (or, in the case of any suit relating to or arising under clause (d), (e) or (f) of Section 5.01 in respect of the Company, ten percent in principal amount of the aggregate Outstanding Securities, or, in the case of any suit relating to or arising under clause (d), (e) or (f) of Section 5.01 in respect of a Guarantor, ten percent in principal amount of the aggregate Outstanding Securities guaranteed hereunder by such Guarantor) 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 Security against the Company on or after the due date expressed in such Security.

SECTION 6.10. Resignation and Removal; Appointment of Successor.

(b) The Trustee may resign at any time with respect to one or more or all series of Securities by giving written notice thereof to the Company. If an instrument of acceptance by a successor Trustee required by Section 6.11 shall not have been delivered to the Trustee within 30 days after the giving of such notice of resignation, the resigning Trustee may petition at the expense of the Company any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series.

(c) The Holders of a majority in aggregate principal amount of the Securities of one or more series (each series voting as a class) or all series at the time Outstanding may at any time remove the Trustee with respect to the applicable series or all series, as the case may be, and by written notice of such action to the Company, the Trustee and the successor Trustee, nominate with respect to the applicable series or all series, as the case may be, a successor Trustee which shall be deemed appointed as successor Trustee with respect to the applicable series unless within ten days after such nomination the Company objects thereto, in which case the Trustee so removed or any Holder of Securities of the applicable series who has been a bona fide holder of a Security or the applicable series for at least six months may, subject to the provisions of Section 5.09 on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to such series.

(1) the Trustee shall fail to comply with Section 310(b) of the Trust Indenture Act pursuant to Section 6.08 hereof after written request therefor by the Company or by any Holder who has been a bona fide Holder of a Security for at least six months, unless the Trustee's duty to resign is stayed in accordance with the provisions of Section 310(b) of the Trust Indenture Act, or

(2) the Trustee shall cease to be eligible under Section 6.09 and shall fail to resign after written request therefor by the Company or by any such Holder, or

(3) the Trustee shall become incapable of acting, or a decree or order for relief by a court having jurisdiction in the premises shall have been entered in respect of the Trustee in an involuntary case under the Federal bankruptcy laws, as now or hereafter constituted, or any other applicable Federal or State, bankruptcy, insolvency or similar law; or a decree or order by a court having jurisdiction in the premises for the appointment of a receiver or custodian or liquidator or trustee or assignee in bankruptcy or insolvency of the Trustee or of its property, or for the winding up of its affairs shall have been entered, or

34

shall make an assignment for the benefit of creditors, or shall fail generally to pay its debts as they become due, or corporate action shall be taken by the Trustee in furtherance of any such action,

then, in any such case, (i) the Company by a Board Resolution may remove the Trustee, or (ii) subject to Section 5.09, any Holder who has been a bona fide Holder of a Security for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

(e) If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of Trustee for any cause, with respect to the Securities of one or more series, the Company, by a Board Resolution, shall promptly appoint a successor Trustee to the vacated office. If, within one year after such resignation, removal or incapability, or the occurrence of such vacancy, a successor Trustee with respect to the Securities of any series shall be appointed by Act of the Holders of a majority in principal amount of the Outstanding Securities of such series delivered to the Company and the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance of such appointment, become the successor Trustee with respect to the Securities of such series and supersede the successor Trustee appointed by the Company. If no successor Trustee shall have been so appointed by the Company or the Holders and accepted appointment in the manner hereinafter provided, any Holder who has been a bona fide Holder of a Security of such series for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series.

Each notice shall include the name of the successor Trustee with respect to the Securities of such series and the address of its Corporate Trust Office.

SECTION 6.11. Acceptance of Appointment by Successor.

Every successor Trustee appointed hereunder shall execute, acknowledge and deliver to the Company and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee; but, on request of the Company or the successor Trustee, such retiring Trustee shall, upon payment of its charges, execute and deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee, and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder, subject nevertheless to its lien, if any, provided for in Section 6.07. Upon request of any such successor Trustee, the Company shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor Trustee all such rights, powers and trusts.

In case of the appointment hereunder of a successor Trustee with respect to the Securities of one or more (but not all) series, the Company, the predecessor Trustee and each successor


35

Trustee with respect to the Securities of any applicable series shall execute and deliver an indenture supplemental hereto which shall contain such provisions as shall be deemed necessary or desirable to confirm that all the rights, powers, trusts and duties of the predecessor Trustee with respect to the Securities of any series as to which the predecessor Trustee is not retiring shall continue to be vested in the predecessor Trustee, and 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 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.

No successor Trustee shall accept its appointment unless at the time of such acceptance such successor Trustee shall be qualified and eligible under this Article.

SECTION 6.12. Merger, Conversion, Consolidation or Succession to Business.

Any corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to all or substantially all of the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, provided such corporation shall be otherwise qualified and eligible under this Article, without the execution or filing of any paper or any further act on the part of any of the parties hereto. In case any Security shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Securities so authenticated with the same effect as if such successor Trustee had itself authenticated such Securities.

SECTION 6.13. Preferential Collection of Claims Against Company.

(a) Subject to Subsection (b) of this Section, if the Trustee shall be or shall become a creditor, directly or indirectly, secured or unsecured, of the Company within three months prior to a default, as defined in Subsection (e) of this Section, or subsequent to such a default, then, unless and until such default shall be cured, the Trustee shall set apart and hold in a special account for the benefit of the Trustee individually, the Holders of the Securities and the holders of other indenture securities, as defined in Subsection (c) of this Section:

(1) an amount equal to any and all reductions in the amount due and owing upon any claim as such creditor in respect of principal or interest, effected after the beginning of such three-month period and valid as against the Company and its other creditors, except any such reduction resulting from the receipt or disposition of any property described in paragraph (2) of this Subsection, or from the exercise of any right of set-off which the Trustee could have exercised if a petition in bankruptcy had been filed by or against the Company upon the date of such default; and

(2) all property received by the Trustee in respect of any claim as such creditor, either as security therefor, or in satisfaction or composition thereof, or otherwise, after the beginning of such three-month period, or an amount equal to the


36

proceeds of any such property, if disposed of, subject, however, to the rights, if any, of the Company and its other creditors in such property or such proceeds.

Nothing herein contained, however, shall affect the right of the Trustee

(A) to retain for its own account (i) payments made on account of any such claim by any Person (other than the Company) who is liable thereon, and (ii) the proceeds of the bona fide sale of any such claim by the Trustee to a third Person, and (iii) distributions made in cash, securities or other property in respect of claims filed against the Company in bankruptcy or receivership or in proceedings for reorganization pursuant to the Federal bankruptcy laws, as now or hereafter constituted, or any other Federal or State bankruptcy, insolvency or similar law;

(B) to realize, for its own account, upon any property held by it as security for any such claim, if such property was so held prior to the beginning of such three-month period;

(C) to realize, for its own account, but only to the extent of the claim hereinafter or mentioned, upon any property held by it as security for any such claim, if such claim was created after the beginning of such three-month period and such property was received as security therefor simultaneously with the creation thereof, and if the Trustee shall sustain the burden of proving that at the time such property was so received the Trustee had no reasonable cause to believe that a default as defined in Subsection (c) of this
Section would occur within three months; or

(D) to receive payment on any claim referred to in paragraph (B) or (C), against the release of any property held as security for such claim as provided in paragraph (B) or
(C), as the case may be, to the extent of the fair value of such property.

For the purposes of paragraphs (B), (C) and (D), property substituted after the beginning of such three-month period for property held as security at the time of such substitution shall, to the extent of the fair value of the property released, have the same status as the property released, and, to the extent that any claim referred to in any of such paragraphs is created in renewal of or in substitution for or for the purpose of repaying or refunding any pre-existing claim of the Trustee as such creditor, such claim shall have the same status as such pre-existing claim.

If the Trustee shall be required to account, the funds and property held in such special account and the proceeds thereof shall be apportioned between the Trustee, the Holders and the holders of other indenture securities in such manner that the Trustee, the Holders and the holders of other indenture securities realize, as a result of payments from such special account and payments of dividends on claims filed against the Company in bankruptcy or receivership or in proceedings for reorganization pursuant to the Federal bankruptcy laws, as now or hereafter constituted, or any other applicable Federal or State bankruptcy, insolvency or similar law, the same percentage of their respective claims, figured before crediting to the claim of the Trustee anything on account of the receipt by it from the Company of the funds and property in such


37

special account and before crediting to the respective claims of the Trustee and the Holders and the holders of other indenture securities dividends on claims filed against the Company in bankruptcy or receivership or in proceedings for reorganization pursuant to the Federal bankruptcy laws, as now or hereafter constituted, or any other applicable Federal or State bankruptcy, insolvency or similar law, but after crediting thereon receipts on account of the indebtedness represented by their respective claims from all sources other than from such dividends and from funds and property so held in such special account. As used in this paragraph, with respect to any claim, the term "dividends" shall include any distribution with respect to such claim, in bankruptcy or receivership or proceedings for reorganization pursuant to the Federal bankruptcy laws, as now or hereafter constituted, or any other applicable Federal or State bankruptcy, insolvency or similar law, whether such distribution is made in cash, securities, or other property, but shall not include any such distribution with respect to the secured portion, if any, of such claim. The court in which such bankruptcy, receivership or proceedings for reorganization is pending shall have jurisdiction (i) to apportion between the Trustee and the Holders and the holders of other indenture securities, in accordance with the provisions of this paragraph, the funds and property held in such special account and proceeds thereof, or (ii) in lieu of such apportionment, in whole or in part, to give to the provisions of this paragraph due consideration in determining the fairness of the distributions to be made to the Trustee and the Holders and the holders of other indenture securities with respect to their respective claims, in which event it shall not be necessary to liquidate or to appraise the value of any securities or other property held in such special account or as security for any such claim, or to make a specific allocation of such distributions as between the secured and unsecured portions of such claims, or otherwise to apply the provision of this paragraph as a mathematical formula.

Any Trustee which has resigned or been removed after the beginning of such three-month period shall be subject to the provisions of this Subsection as though such resignation or removal had not occurred.

SECTION 6.14. Appointment of Authenticating Agent.

At any time when any of the Securities remain Outstanding the Trustee may appoint an Authenticating Agent or Agents which shall be authorized to act on behalf of the Trustee to authenticate Securities issued upon exchange, transfer or partial redemption thereof or pursuant to Section 3.06, and Securities so authenticated shall be entitled to the benefits of this Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee hereunder. Wherever reference is made in this Indenture to the authentication and delivery of Securities by the Trustee or the Trustee's certificate of authentication, such reference shall be deemed to include authentication and delivery on behalf of the Trustee by an Authenticating Agent and a certificate of authentication executed on behalf of the Trustee by an Authenticating Agent. Each Authenticating Agent shall be acceptable to the Company and shall at all times be a bank or trust company or corporation organized and doing business and in good standing under the laws of the United States of America, or of any State, authorized under such laws to act as Authenticating Agent, having a combined capital and surplus of not less than $1,500,000 and subject to supervision or examination by Federal or State authorities. If such Authenticating Agent publishes reports of condition at least annually, pursuant to law or to the requirements of the aforesaid supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such Authenticating Agent shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. In case at any time an Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, such Authenticating Agent shall resign immediately in the manner and with the effect specified in this Section.

Any corporation into which an Authenticating Agent may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which such Authenticating Agent shall be a party, or any corporation succeeding to the corporate agency or corporate trust business of an Authenticating Agent, shall continue to be an Authenticating Agent without the execution or filing of any paper or any further act on the part of the Trustee or the Authenticating Agent.

An Authenticating Agent may at any time resign by giving written notice of resignation to the Trustee and to the Company. The Trustee may at any time terminate the agency of an Authenticating Agent by giving written notice of termination to such Authenticating Agent and to the Company. Upon receiving such a notice of resignation or upon such a termination, or in case at any time such Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, the Trustee may appoint a successor Authenticating Agent which shall be acceptable to the Company and shall mail notice of such appointment to all Holders, as their names and addresses appear on the Security Register. Any successor Authenticating Agent upon acceptance of its appointment hereunder shall become vested with all the rights, powers and duties of its predecessor hereunder, with like effect as if originally named as an Authenticating Agent herein. No successor Authenticating Agent shall be appointed unless eligible under the provisions of this Section.

The Trustee agrees to pay to each Authenticating Agent from time to time reasonable compensation for its services under this Section, and the Trustee shall be entitled to be reimbursed for such payments, subject to the provisions of Section 6.07.

Such written statement shall specify the basis of such opinion. If the Commission, after opportunity for a hearing upon the objections specified in the written statement so filed, shall enter an order refusing to sustain any of such objections or if, after the entry of an order sustaining one or more of such objections, the Commission shall find, after notice and opportunity for hearing, that all the objections so sustained have been met and shall enter an order so declaring, the Trustee shall mail copies of such material to all such Holders with reasonable promptness after the entry of such order and the renewal of such tender; otherwise the Trustee shall be relieved of any obligation or duty to such applicants respecting their application.

(4) any change to the amount, interest rate and maturity date of all other indebtedness owing by the Company (or by any other obligor on the Securities) to the Trustee in its individual capacity, on the date of such report, with a brief description of any property held as collateral security therefor, except an indebtedness based upon a creditor relationship arising in any manner described in Section 6.13(b)(2), (3), (4) or (6); (5) any change to the property and funds, if any, physically in the possession of the Trustee as such on the date of such report;

Delivery of such reports, information and documents to the Trustee is for informational purposes only and the Trustee's receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company's compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers' Certificates).

The Company may consolidate with, or sell or convey all or substantially all of its assets to, or merge with or into any other corporation, provided that in any such case, (i) either the Company shall be the continuing corporation, or the successor corporation shall be a corporation organized and existing under the laws of the United States of America or a State thereof and such successor corporation shall expressly assume the due and punctual payment of the principal of and interest on all the Securities, according to their tenor and the due and punctual performance and observance of all of the covenants and conditions of this Indenture to be performed by the Company by supplemental indenture satisfactory to the Trustee, executed and delivered to the Trustee by such corporation, and (ii) the Company or such successor corporation, as the case may be, shall not, immediately after such merger or consolidation, or such sale or conveyance, be in default in the performance of any such covenant or condition.

SECTION 8.02. Rights and Duties of Successor Corporation.

In case of any such consolidation, merger, sale or conveyance and upon any such assumption by the successor corporation, such successor corporation shall succeed to and be substituted for the Company, with the same effect as if it had been named herein as the Company, and the predecessor corporation shall be relieved of any obligation under this Indenture and the Securities and, in the event of such sale or conveyance may be dissolved and/or liquidated. Such successor corporation thereupon may cause to be signed, and may issue either in its own name or in the name of the Company, any or all of the Securities issuable hereunder which theretofore shall not have been signed by the Company and delivered to the Trustee; and, upon the order of such successor corporation, 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 Securities which previously shall have been signed and delivered by the officers of the Company to the Trustee for authentication, and any Securities which such successor corporation thereafter shall cause to be signed and delivered to the Trustee for that purpose. All the Securities so issued shall in all respects have the same legal rank and benefit under this Indenture as the Securities theretofore or thereafter issued in accordance with the terms of this Indenture as though all of such Securities 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 Securities thereafter to be issued as may be appropriate.

SECTION 8.03. Securities to be Secured in Certain Events.

If, after giving effect to any such consolidation or merger of the Company with or into any other corporation, or after giving effect to any sale or conveyance of the property of the Company as an entirety or substantially as an entirety to any other corporation, the corporation


45

formed by or resulting or surviving therefrom or which shall have received such property would have outstanding any Debt (as defined in Section 10.08) secured by any Mortgage (as defined in Section 10.08) on any Principal Property, or on any shares of stock or Debt (as defined in Section 10.08) of any Restricted Subsidiary, which such Debt could not at such time be incurred by such corporation under Section 10.08 without equally and ratably securing the Securities, the Company, prior to such consolidation, merger, sale or conveyance, will secure the Outstanding securities hereunder, equally and ratably with (or prior to) the Debt (as defined in Section 10.08) secured by such Mortgage.

SECTION 8.04. Officers' Certificate and Opinion of Counsel.

SECTION 8.05. Limitation on Lease of Properties as Entirety.

(C) the Company delivers to the Trustee an Officers' Certificate and an Opinion of Counsel, each stating that such consolidation or merger, and, if applicable, the assumption by the resulting or surviving Person of such Guarantor's obligations under each of its Guarantees hereunder, complies with the Indenture.

If the conditions set forth in (A), (B) and (C) above are otherwise satisfied, the consolidation or merger of any Guarantor with or into any Person shall not be or be deemed to be


46

a violation, default or breach by the Company or any Guarantor of any of the provisions of Article XV hereof.

In the event that a Guarantor is disposed of in its entirety (whether by merger, consolidation or sale of its capital stock), such Guarantor shall be released from its obligations under each of its Guarantees.

(d) to provide for the issuance under this Indenture of Securities in coupon form (including Securities registrable as to principal only) and to provide for exchangeability of such Securities with the Securities issued hereunder in fully registered form and to make all appropriate changes for such purpose; or

(e) to establish the form or terms of Securities of any series as permitted by Sections 2.01 and 3.01; or


47

(f) to cure any ambiguity or to correct or supplement any provision contained herein or in any supplemental indenture which may be defective or inconsistent with any other provision contained herein or in any supplemental indenture, or to make such other provisions in regard to matters or questions arising under this Indenture which shall not adversely affect the interests of any Holder; or

With the consent (evidenced as provided in Section 1.04) of the Holders of not less than 50% in aggregate principal amount of the Outstanding Securities of all series affected by such supplemental indenture (voting as one class), the Company, when authorized by a Board Resolution, and the Trustee may from time to time and at any time enter into an indenture or indentures supplemental hereto 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 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 Securities of each such series; provided, however, that no such supplemental indenture shall (i) change the Stated Maturity of any Security, or reduce the rate or change the time of payment of interest thereon, or reduce the principal amount thereof or any premium thereon, or make the principal thereof or interest or premium thereon payable in any coin or currency other than that provided in the Securities or reduce the amount of the principal of an Original Issue Discount Security that would be due and payable upon an acceleration of the Maturity thereof pursuant to Section 5.02 or the amount thereof provable in bankruptcy pursuant to Section 5.03 or impair the right to institute suit for enforcement of any such payment on or after the Stated Maturity thereof (or, in the case of redemption, on or after the Redemption Date), or adversely affect the right of repayment, if any, at the option of the Holder without the consent of the Holder of each Security so affected, or (ii) reduce the aforesaid percentage of Securities, the Holders of which are required to consent to any such supplemental indenture, or the Holders of which are required for any waiver (of compliance with certain provisions of this Indenture or certain defaults hereunder and their consequences) provided for in this Indenture, without the consent of the Holder of each Security so affected. A supplemental indenture which changes or eliminates any covenant or other provision of this Indenture which has expressly been included solely for the benefit of one or more particular

The Company may at any time, for the purpose of obtaining the satisfaction and discharge of this Indenture or for any other purpose, pay, or by Company Order direct any Paying Agent to pay, to the Trustee all sums held in trust by the Company or such Paying Agent, 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; and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be released from all further liability with respect to such money.

Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of or premium, if any, or interest on any Security and remaining unclaimed for three years after such principal or premium, if any or interest has become due and payable shall be paid to the Company on Company Request, or (if then held by the Company) shall be discharged from such trust; and the Holder of such Security shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Company cause to be published once, in a newspaper published in the English language, customarily published on each Business Day and of general circulation in the Borough of Manhattan, The City of New York, notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such publication, any unclaimed less than 30 days from the date of such publication, any unclaimed balance of such money then remaining will be repaid to the Company.

SECTION 10.04. 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, (1) 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 (2) 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 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 10.05. Maintenance of Principal Properties.

The Company will cause all Principal Properties to be maintained and kept in good physical condition, repair and working order and supplied with all necessary equipment and will cause to be made all necessary physical 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 or restrict the sale, abandonment or other disposition of any of such properties if such section is, in the judgment of the Company, desirable in the conduct of the business of the Company and its Subsidiaries as a whole.

SECTION 10.06. Statement 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 ending after the date hereof, a statement (which shall not be deemed an Officers' Certificate and need not conform with any of the provisions of Section 1.02) signed by the principal executive officer, principal financial officer or principal accounting officer of the Company and by the Treasurer or the Secretary or any Assistant Treasurer or any Assistant Secretary the Company, stating that in the course of the performance by the signers of their duties as officers of the Company and based upon a review made under their supervision of the activities of the Company during such year and of the Company's performance under this Indenture they would normally obtain knowledge whether or not the Company is in default in the performance of any covenant or agreement contained herein, stating whether or not they have obtained knowledge that the Company is in default in the performance of any such covenant or agreement, and if so, specifying each such default of which the signers have knowledge and the nature thereof. For purposes of this Section, such compliance shall be determined without regard to any period of grace or requirement of notice provided under this Indenture.

The Company shall deliver to the Trustee, as soon as possible and in any event within five days after the Company becomes aware of the occurrence of any Event of Default or an event which, with notice or the lapse of time or both, would constitute an Event of Default, an Officers' Certificate setting forth the details of such Event of Default or default and the action which the Company proposes to take with respect thereto.

SECTION 10.07. Corporate Existence.

SECTION 10.08. Limitation on Secured Debt.

The Company will not itself, and will not permit any Restricted Subsidiary to, incur, issue, assume or guarantee any notes, bonds, debentures or other similar evidences of indebtedness (such Notes, bonds, debentures or other similar evidences of indebtedness being hereinafter in this Article called "Debt"), secured by pledge of, or mortgage or other lien on, any Principal Property owned or leased by the Company or any Restricted Subsidiary, or any shares of stock or Debt of any Restricted Subsidiary (pledges, mortgages and other liens being


52

hereinafter in this Article called "Mortgage" or "Mortgages"), without effectively providing that the Securities (together with, if the Company shall so determine, any other Debt of the Company or such Restricted Subsidiary then existing or thereafter created which is not subordinated to the Securities) shall be secured equally and ratably with (or prior to) such secured Debt, so long as such secured Debt shall be so secured, unless, after giving effect thereto, the aggregate amount of all such secured debt (not including secured Debt permitted to be secured under clauses (1) to (7) below) plus the aggregate "value" (as defined in Section 10.09) of all sale and leaseback transactions (as defined in Section 10.09 but not including sale and leaseback transactions the proceeds of which have been or will be applied in accordance with Section 10.09(2)) would not exceed [5]% of Consolidated Net Tangible Assets; provided, however, that this Section shall not apply to, and there shall be excluded from secured Debt in any computation under this Section, Debt secured by:

(1) Mortgages on property of, or on any shares of stock or Debt of, the Company or a Restricted Subsidiary, existing on the date hereof;

(2) Mortgages on property of, or on any shares of stock or Debt of, any corporation existing at the time such corporation becomes a Restricted Subsidiary;

(3) Mortgages on property of a Restricted Subsidiary securing exclusively indebtedness of such Subsidiary owing to the Company or any other Restricted Subsidiary;

(4) Mortgages in favor of the United States of America, or any State or agency thereof or of any foreign country, or any agency, department or other instrumentality thereof, to secure progress, advance or other payments pursuant to any contract or provision of any statute;

(5) Mortgages on property, shares of stock or Debt existing at the time of acquisition thereof (including acquisition through merger or consolidation) or to secure the payment of all or any part of the purchase price or construction cost thereof or to secure any Debt incurred prior to, at the time of, or within 24 months after, the acquisition of such property or shares or Debt or the completion of any such construction for the purpose of financing all or any part of the purchase price or construction cost thereof;

(6) Mortgages on property of the Company or a Restricted Subsidiary to secure the payment of all or any part of the costs of exploration, drilling, mining, or development thereof for the purpose of increasing the production and sale or other disposition of oil, gas or other minerals or any indebtedness incurred to provide funds for all or any such purposes; and

(7) any extension, renewal or replacement (or successive extensions, renewals or replacements), as a whole or in part, of any Mortgage referred to in the foregoing clauses (1) to (6), inclusive; provided, that (i) such extension, renewal or replacement Mortgage shall be limited to all or a part of the same property, shares of stock or Debt that secured the Mortgage extended, renewal or replaced (plus improvements on such property) and (ii) the Debt secured by such Mortgage at such time is not increased.


53

For purposes of this Section 10.08, the sale or other transfer of any interest in property of the character commonly referred to as a "production payment" shall not be deemed to create secured Debt.

SECTION 10.09. Limitation on Sales and Leasebacks.

The Company will not itself, and it will not permit any Restricted Subsidiary to, enter into any arrangement with any bank, insurance company or other lender or investor (not including the Company or any Restricted Subsidiary) or to which any such lender or investor is a party, providing for the leasing by the Company or any such Restricted Subsidiary for a period, including renewals, in excess of three years of any Principal Property owned or leased by the Company or such Restricted Subsidiary which has been or is to be sold or transferred, more than 120 days after the completion of construction and commencement of full operation thereof, by the Company or any such Restricted Subsidiary to such lender or investor or to any person to whom funds have been or are to be advanced by such lender or investor on the security of such Principal Property (herein referred to as a "sale and leaseback transaction") unless either:

(1) the Company or such Restricted Subsidiary could create Debt secured by a Mortgage pursuant to Section 10.08 on the Principal Property to be leased back equal in amount to the amount realized or to be realized upon such sale and leaseback transaction without equally and ratably securing the Securities, or

(2) the Company, within 120 days after the sale or transfer shall have been made by the Company or by any such Restricted Subsidiary, applies an amount equal to the value of the Principal Property so sold and leased back at the time of entering into such arrangement to the retirement of Funded Debt of the Company; provided, that the amount to be applied to the retirement of Funded Debt of the Company shall be reduced by (a) the principal amount of any Securities delivered within 120 days after such sale to the Trustee for retirement and cancellation, and (b) the principal amount of Funded Debt, other than Securities, voluntarily retired by the Company within 120 days after such sale. Notwithstanding the foregoing, no retirement referred to in this clause (2) may be effected by payment at maturity or pursuant to any mandatory sinking fund payment or any mandatory prepayment provision.

As used in this Section 10.09, the term "value" shall mean, with respect to a sale and leaseback transaction, as of any particular time an amount equal to the greater of (i) the net proceeds of sale of the property leased pursuant to such sale and leaseback transaction, or (ii) the fair value of such property at the time of entering into such sale and leaseback transaction as determined by the Board of Directors, in each case multiplied by a fraction of which the numerator is the number of full years of remaining term of the lease (without regard to renewal options) and the denominator is the full years of the full term of the lease (without regard to renewal options).

It is understood that transactions entered into pursuant to Section 168(f)(8) of the Internal Revenue Code, as amended, are not Debt secured by a Mortgage within the meaning of Section 10.08 or sale and leaseback transactions prohibited by this Section 10.09.


54

SECTION 10.10. Waiver of Certain Covenants.

The Company may omit in any particular instance to comply with any covenant or condition set forth in Section 10.04, 10.05 and 10.07 through 10.09 or any covenant added for the benefit of any series of Securities as contemplated by Section 3.01, if before or after the time for such compliance the Holders of at least a majority in principal amount of the Securities at the time Outstanding shall, by Act of such Holders, waive such compliance in such instance, but no such waiver shall extend to or affect such covenant or condition except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the Company and the duties of the Trustee in respect of any such covenant or condition shall remain in full force and effect.

SECTION 10.11. Calculation of Original Issue Discount.

The Company shall file with the Trustee promptly at the end of each calendar year (i) a written notice specifying the amount of original issue discount (including daily rates and accrual periods) accrued on Outstanding Securities as of the end of such year and (ii) such other specific information relating to such original issue discount as may then be relevant under the Internal Revenue Code of 1986, as amended from time to time.

ARTICLE ELEVEN

REDEMPTION OF SECURITIES

SECTION 11.01. Applicability of Article. The provisions of this Article shall be applicable to the Securities of any series which are redeemable before their maturity except as otherwise specified as contemplated by Section 3.01 for Securities of such series.

SECTION 11.02. Notice of Redemption; Selection of Securities. In case the Company shall desire to exercise the right to redeem all, or, as the case may be, any part of the Securities of any series in accordance with their terms, it shall fix a date for redemption and shall mail or cause to be mailed a notice of such redemption at least 30 and not more than 60 days prior to the date fixed for redemption to the Holders of Securities of such series so to be redeemed as a whole or in part at their last addresses as the same appear on the Security Register. Such mailing shall be by first class mail. The notice if mailed 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 by mail or any defect in the notice to the Holder of any 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 Security of such series.

Each such notice of redemption shall specify the date fixed for redemption, the redemption price at which 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 Securities, that any interest accrued to the date fixed for redemption will be paid as specified in said notice, and that on and after said date any interest thereon or on the portions thereof to be redeemed will cease to accrue. If less than all the Securities of a series are to be redeemed the notice of redemption shall specify the numbers of the Securities of that series to be redeemed. In case any Security of a series is to be redeemed in part only, the notice of redemption shall state the portion of the principal amount thereof to be redeemed and shall state that on and after the date fixed for


55

redemption, upon surrender of such Security, a new Security or Securities of that series in principal amount equal to the unredeemed potion thereof will be issued.

On or before the redemption date specified in the notice of redemption given as provided in this Section 11.02, the Company will deposit with the Trustee or with one or more paying agents an amount of money sufficient to redeem on the redemption date all the Securities or portions thereof so called for redemption at the appropriate redemption price, together with accrued interest to the date fixed for redemption.

If all or less than all the Securities of a series are to be redeemed the Company will give the Trustee notice not less than 60 days prior to the redemption date as to the aggregate principal amount of Securities to be redeemed and the Trustee shall select, in such manner as in its sole discretion it shall deem appropriate, the Securities of that series or portions thereof (in multiples of $1,000, except as otherwise set forth in the applicable form of Security) to be redeemed.

SECTION 11.03. Payment of Securities Called for Redemption. If notice of redemption has been given as provided in Section 11.02 or Section 12.03, the Securities or portions of Securities of the series with respect to which such notice has been given shall become due and payable on the date and at the place or places 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 Securities at the applicable redemption price, together with any interest accrued to said date) any interest on the Securities or portions of Securities of any series so called for redemption shall cease to accrue. On presentation and surrender of such Securities at a place of payment in said notice specified, the said 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.

Upon presentation of any Security redeemed in part only, the Company shall execute and the Trustee shall authenticate and deliver to the Holder thereof, at the expense of the Company, a new Security or Securities of such series, of authorized denominations, in principal amount equal to the unredeemed portion of the Security so presented.

ARTICLE TWELVE

SINKING FUNDS

SECTION 12.01. Applicability of Article. The provisions of this Article shall be applicable to any sinking fund for the retirement of Securities of a series except as otherwise specified as contemplated by Section 3.01 for Securities of such series.

The minimum amount of any sinking fund payment provided for by the terms of Securities of any series is herein referred to as a "mandatory sinking fund payment", and any payment in excess of such minimum amount provided for by the terms of Securities of any series is herein referred to as an "optional sinking fund payment".

SECTION 12.02. Satisfaction of Mandatory Sinking Fund Payments with Securities. In lieu of making all or any part of any mandatory sinking fund payment with respect to any Securities of a series in cash, the Company may at its option (a) deliver to the Trustee Securities


56

of that series theretofore purchased or otherwise acquired by the Company, or
(b) receive credit for the principal amount of Securities of that series which have been previously delivered by the Trustee to the Company which have been redeemed either at the election of the Company pursuant to the terms of such Securities or through the application of permitted optional sinking fund payments pursuant to the terms of such Securities; provided that such Securities have not been previously so credited. Such Securities shall be received and credited for such purpose by the Trustee at the Redemption Price specified in such Securities for redemption through operation of the sinking fund and the amount of such mandatory sinking fund payment shall be reduced accordingly.

SECTION 12.03. Redemption of Securities for Sinking Fund. Not less than 60 days prior to each sinking fund payment date for any series of Securities, the Company will deliver to the Trustee a certificate signed by the Treasurer or any Assistant Treasurer of the Company specifying the amount of the next ensuing sinking fund payment for that series pursuant to the terms of that series, the portion thereof, if any, which is to be satisfied by payment of cash and the portion thereof, if any, which is to be satisfied by delivering or crediting Securities of that series pursuant to Section 12.02 (which Securities will, if not previously delivered, accompany such certificate) and whether the Company intends to exercise its right to make a 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. In the case of the failure of the Company to deliver such certificate (or to deliver the Securities specified in this paragraph), 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 Securities subject to a mandatory sinking fund payment without the option to deliver or credit Securities as provided in Section 12.02 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 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 Securities at the Redemption Price specified in such Securities for operation of the sinking fund together with accrued interest to the date fixed for redemption. Any sinking fund moneys not so applied or allocated by the Trustee to the redemption of 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
12.03. Any and all sinking fund moneys with respect to the Securities of any particular series held by the Trustee on the last sinking fund payment date with respect to Securities of such series and not held for the payment or redemption of particular 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 Securities of that series at maturity.

The Trustee shall select the Securities to be redeemed upon such sinking fund payment date in the manner specified in the last paragraph of
Section 11.02 and the Company shall cause


57

notice of the redemption thereof to be given in the manner provided in Section 11.02 except that the notice of redemption shall also state that the Securities are being redeemed by operation of the sinking fund. Such notice having been duly given, the redemption of such Securities shall be made upon the terms and in the manner stated in Section 11.03.

On or before each sinking fund payment date, the Company shall pay to the Trustee in cash a sum equal to any interest accrued to the date fixed for redemption of Securities or portions thereof to be redeemed on such sinking fund payment date pursuant to this Section.

The Trustee shall not redeem any Securities of a series with sinking fund moneys or mail any notice of redemption of such Securities by operation of the sinking fund for such series during the continuance of a default in payment of interest on such Securities or of any Event of Default (other than an Event of Default occurring as a consequence of this paragraph) with respect to such Securities, except that if the notice of redemption of any such Securities shall theretofore have been mailed in accordance with the provisions hereof, the Trustee shall redeem such Securities if cash sufficient for that purpose shall be deposited with the Trustee for that purpose in accordance with the terms of this Article. 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 Securities; provided, however, that in case such Event of Default or default shall have cured or waived as provided herein, such moneys shall thereafter be applied on the next sinking fund payment date for such Securities on which such moneys may be applied pursuant to the provisions of this Section.

ARTICLE THIRTEEN

SECTION 13.03. Call of Meetings by Company or Holders.

In case at any time the Company, pursuant to a Board Resolution, or the Holders of not less than 10% in aggregate principal amount of the Outstanding Securities of any or all series, as the case may be, shall have requested the Trustee to call a meeting of Holders of Securities of all series, if they hold not less than 10% of all Outstanding Securities, or a meeting of Holders of Outstanding Securities of the series of which they hold not less than 10%, to take any action authorized in Section 13.01, by written request setting forth in reasonable detail the action proposed to be taken at the meeting, and the Trustee shall not have mailed notice of such meeting within 20 days after receipt of such request, then the Company or the Holders in the amount above specified may determine the time and the place for such meeting and may call such meeting to take any action authorized in Section 13.01 by mailing notice thereof as provided in Section 13.02.

SECTION 13.05. Regulations.

Notwithstanding any other provision of this Indenture, the Trustee may make such reasonable regulations as it may deem advisable for any meeting of Holders, in regard to the appointment of proxies, the appointment and duties of inspectors of votes, the submission and examination of proxies, certificates and other evidence of the right to vote, and such other matters concerning the conduct of the meeting as it shall think fit. Except as otherwise permitted or required by any such regulations, the holding of Securities shall be proved in the manner specified in Section 1.04 and the appointment of any proxy shall be proved in the manner specified in said Section 1.04; provided, however, that such regulations may provide that written instruments appointing proxies, regular on their face, may be presumed valid and genuine without the proof hereinbefore or in said Section 1.04 specified.

The Trustee shall, by an instrument in writing, appoint a temporary chairman of the meeting, unless the meeting shall have been called by the Company or the Holders as provided in Section 13.03, in which case the Company or the Holders calling the meeting, as the case may be, shall in like manner appoint a temporary chairman. A permanent chairman and a permanent secretary of the meeting may be elected by vote of the Holders of a majority in principal amount

Notwithstanding anything in this Section to the contrary, at any meeting of Holders, the presence of Persons holding or representing Securities with respect to which such meeting is being held in an aggregate principal amount sufficient under the appropriate provision of this Indenture to take action on any business for the transaction of which such meeting was called shall constitute a quorum, but, if less than a quorum is present, the Persons holding or representing a majority in aggregate principal amount of such Securities represented at the meeting may adjourn such meeting with the same effect, for all intents and purposes, as though a quorum had been present.

SECTION 13.06. Voting.

The vote upon any resolution submitted to any meeting of Holders of Securities with respect to which such meeting is being held shall be by written ballots on which shall be subscribed the signature of such Holders or proxies and the serial number or numbers and the principal amounts of the Securities held or represented by them.

At any time prior to (but not after) the evidencing to the Trustee, in the manner provided in Section 1.04, of the taking of any action by the Holders of the percentage in aggregate principal amount of the Securities specified in this Indenture in connection with such action, any Person who is the Holder of a Security the serial number of which is included in the Securities, the Holders of which have consented to such action may, by filing written notice with the Trustee at the Corporate Trust Office and upon proof of holding as provided in
Section 1.04, revoke such consent so far as concerns such Security, or if such Security is a Predecessor Security, so far as concerns the portion of such Security of which such Persons is the Holder. Except as aforesaid any such consent given by the Holder of any Security shall be conclusive and binding upon such Holder and upon all future Holders and owners of such Security and of any Security issued in exchange therefor or in lieu thereof, irrespective of whether or not any notation in regard thereto is made upon such Security. Any action taken by the Holders of the percentage in aggregate principal amount of the Securities 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.

ARTICLE FIFTEEN

GUARANTEES

SECTION 15.01. Guarantees. Each Guarantor of a particular series of Securities hereby unconditionally guarantees (each such guarantee to be referred to herein as a "Guarantee"), jointly and severally with each other Guarantor of the Securities of that series, if any, to each Holder of such Securities authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of this Indenture, such Securities or the obligations of the Company hereunder or thereunder, (i) the due and punctual payment of the principal of and any premium or interest on such Securities, whether at maturity or on an interest payment date, by acceleration, pursuant to an offer to purchase such Securities or otherwise, and interest on the overdue principal of and interest, if any, on such Securities, if lawful, and all other obligations of the Company to the Holders of such Securities or the Trustee hereunder or thereunder shall be promptly paid in full, all in accordance with the terms hereof and thereof including all amounts payable to the Trustee under Section 6.07 hereof, and (ii) in case of any extension of time of payment or renewal of any such Securities or any of such other obligations, the same shall be promptly paid in full when due or to be performed in accordance with the terms of the extension or renewal, whether at stated maturity, by acceleration or otherwise.

If the Company fails to make any payment when due of any amount so guaranteed for whatever reason, each Guarantor of the Securities of that series shall be obligated, jointly and severally with each other such Guarantor, if any, to pay the same immediately. Each Guarantor hereby agrees that its obligations hereunder shall be continuing, absolute and unconditional, irrespective of, and shall be unaffected by, the validity, regularity or enforceability of the Securities, this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Securities or the Trustee with respect to any provisions hereof or thereof, the recovery of any judgment against the Company, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of such Guarantor. Each Guarantor hereby waives diligence, presentment, demand of payment, demand of performance, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, the benefit of discussion, protest, notice and all demand whatsoever and covenants that its Guarantee shall not be discharged except by complete performance of the obligations contained in the Securities guaranteed by such Guarantee, in this Indenture and in this Article Fifteen. If any Holder of Securities of a series guaranteed hereby or the Trustee is required by any court or otherwise to return to the Company or any Guarantor of such Securities, or any custodian, trustee, liquidator or other similar official acting in relation to the Company or any Guarantor of such Securities, any amount paid by the Company or any Guarantor of such Securities to the Trustee or such Holder, this Article Fifteen, to the extent theretofore discharged with respect to any Guarantee of such Securities, shall be reinstated in full force and effect. Each Guarantor agrees that it shall not be entitled to any right of subrogation in relation to the Holders of Securities of a series guaranteed hereby by such Guarantor in respect of any obligations guaranteed hereby by such Guarantee until payment in full of all such obligations. Each Guarantor further agrees that, as between such Guarantor, on the one hand, and the Holders of Securities of a series guaranteed hereby by such Guarantor and the Trustee on the other hand, (i) the maturity of the obligations guaranteed hereby by such Guarantee may be accelerated as provided in Article Five hereof for


64

the purposes of such Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby and (ii) in the event of any acceleration of such obligations as provided in Article Five hereof, such obligations (whether or not due and payable) shall forthwith become due and payable by such Guarantor, jointly and severally with any other Guarantor of such Securities, for the purpose of this Article Fifteen. In addition, without limiting the foregoing, upon the effectiveness of an acceleration under Article Five, the Trustee may make a demand for payment on the Securities under any Guarantee thereof not discharged.

With respect to each Guarantee by a Guarantor, such Guarantor shall be subrogated to all rights of the Holder of any Securities guaranteed hereby by such Guarantee against the Company in respect of any amounts paid to such Holder by such Guarantor pursuant to the provisions of such Guarantee; provided that such Guarantor shall not be entitled to enforce, or to receive any payments arising out of or based upon, such right of subrogation until the principal of and interest on all such Securities shall have been paid in full.

The Guarantees provided in this Section 15.01 shall not be valid or become obligatory for any purpose with respect to a Security until the certificate of authentication on such Security shall have been signed by the Trustee or any duly appointed agent.

SECTION 15.02. Obligations of the Guarantor Unconditional. Nothing contained in this Article Fifteen or elsewhere in this Indenture or in any Security is intended to or shall impair, as between a Guarantor and the Holders of the Securities guaranteed by such Guarantor's Guarantee, the obligations of such Guarantor, which are absolute and unconditional, to pay to such Holders the principal of and interest on such Securities as and when the same shall become due and payable in accordance with the provisions of such Guarantee or is intended to or shall affect the relative rights of such Holders and creditors of such Guarantor, nor shall anything herein or therein prevent the Trustee or any such Holder from exercising all remedies otherwise permitted by applicable law upon Default under this Indenture in respect of cash, property or securities of such Guarantor received upon the exercise of any such remedy;

Upon any distribution of assets of a Guarantor referred to in this Article Fifteen, the Trustee, subject to the provisions of Sections 6.01 and 6.03, and the Holders of the Securities guaranteed hereby by such Guarantor shall be entitled to rely upon any order or decree made by any court of competent jurisdiction in which such dissolution, winding up, liquidation or reorganization proceedings are pending, or a certificate of the liquidating trustee or agent or other person making any distribution to the Trustee or to such Holders, for the purpose of ascertaining the persons entitled to participate in such distribution, the holders of other indebtedness of such Guarantor, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Article Fifteen.

SECTION 15.03. Article Fifteen Not To Prevent Events of Default. The payment of principal or interest on the Securities of any series by reason of any provision in this Article Fifteen shall not be construed as preventing the occurrence of an Event of Default.

SECTION 15.04. Execution and Delivery of Guarantee. To evidence a Guarantee, the Guarantor shall endorse a Guarantee Notation, substantially in the form of Exhibit A hereto, on each Security authenticated and delivered by the Trustee that is guaranteed by such Guarantee.


65

Each Guarantor hereby agrees that its Guarantee shall remain in full force and effect notwithstanding any failure to endorse the Guarantee Notation on each such Security.

If an officer whose signature is on the Securities guaranteed hereby no longer holds that office at the time the Trustee authenticates the Security on which a notation of a Guarantee is endorsed, such Guarantee shall be valid nevertheless.

The delivery of any Security by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of each Guarantee thereof.
