Incorporated, PaineWebber Incorporated, Prudential Securities Incorporated and Salomon Smith Barney Inc. are acting as representatives (in such capacity, the "Representatives"), with respect to the issue and sale by the Trust and the - ----------------------- "Trust Originated Preferred Securities" and "TOPrS" are service marks of Merrill Lynch & Co., Inc.

purchase by the Underwriters, acting severally and not jointly, of the respective numbers of 8.16% Trust Originated Preferred Securities (liquidation amount of $25 per preferred security) of the Trust (the "Preferred Securities") set forth in said Schedule A, and with respect to the grant by the Trust to the Underwriters, acting severally and not jointly, of the option described in Section 2(b) hereof to purchase all or any part of the additional 1,000,000 Preferred Securities to cover over-allotments, if any. The aforesaid 20,000,000 Preferred Securities (the "Initial Securities") to be purchased by the Underwriters and all or any part of the 1,000,000 Preferred Securities subject to the option described in Section 2(b) hereof (the "Option Securities") are hereinafter called, collectively, the "Securities." The Preferred Securities will be guaranteed by the Guarantor with respect to distributions and payments upon liquidation, redemption and otherwise (the "Preferred Securities Guarantee") pursuant to the Preferred Securities Guarantee Agreement (the "Preferred Securities Guarantee Agreement"), dated as of January 20, 1999, between the Guarantor and The Bank of New York, as Trustee (the "Preferred Guarantee Trustee"), and entitled to the benefits of certain backup undertakings described in the Prospectus (as defined herein) with respect to the Guarantor's agreement pursuant to the Officers' Certificate (as defined herein) to pay all expenses relating to administration of the Trust (the "Undertakings"). The Offerors understand that the Underwriters propose to make a public offering of the Securities as soon as the Representatives deem advisable after this Agreement has been executed and delivered. The entire proceeds from the sale of the Securities will be combined with the entire proceeds from the sale by the Trust to the Guarantor of its common securities (the "Common Securities") guaranteed by the Guarantor, to the extent set forth in such guarantee, with respect to distributions and payments upon liquidation and redemption (the "Common Securities Guarantee" and, together with the Preferred Securities Guarantee the "Guarantees") pursuant to a Common Securities Guarantee Agreement (the "Common Securities Guarantee Agreement" and, together with the Preferred Securities Guarantee Agreement, the "Guarantee Agreements"), dated as of January 20, 1999 between the Guarantor and The Bank of New York, as Trustee, and will be used by the Trust to purchase $515,463,925 aggregate principal amount of 8.16% Subordinated Deferrable Interest Notes due 2039 (the "Subordinated Debt Securities") to be issued by Occidental and, if all or any part of the Option Securities are purchased, up to an additional $25,773,200 aggregate principal amount of Subordinated Debt Securities (the "Option Subordinated Debt Securities"). The Preferred Securities and the Common Securities will be issued pursuant to the amended and restated declaration of trust of the Trust, dated as of January 20, 1999 (the "Declaration"), among the Guarantor, as Sponsor, the trustees named therein (the "Trustees") and the holders from time to time of undivided beneficial interests in the assets of the Trust. The Subordinated Debt Securities will be issued pursuant to an indenture, dated as of January 20, 1999 (the "Base Indenture"), among the Guarantor and The Bank of New York, as trustee (the "Debt Trustee"), and an officers' certificate as provided for in the Base Indenture (the "Officers' Certificate," and together with the Base Indenture and any other amendments or supplements thereto, the "Indenture"). The Offerors have filed with the Securities and Exchange Commission (the "Commission") a shelf registration statement on Form S-3 (No. 333-69303) and, if applicable, one or more amendments thereto covering the registration of (i) the Securities and (ii) the debt securities of Occidental under the Securities Act of 1933, as amended (the "1933 Act"), and the offering thereof from time to time in accordance with Rule 415 of the rules and regulations of the 2

Commission under the 1933 Act (the "1933 Act Regulations"). Such registration statement (as amended, if applicable) has been declared effective by the Commission and the Base Indenture has been qualified under the Trust Indenture Act of 1939, as amended (the "1939 Act"). Promptly after execution and delivery of this Agreement, the Offerors will either (i) prepare and file a prospectus in accordance with the provisions of Rule 424(b) ("Rule 424(b)") of the 1933 Act Regulations or (ii) if the Offerors have elected to rely upon Rule 434 ("Rule 434") of the 1933 Act Regulations, prepare and file a term sheet (a "Term Sheet") in accordance with the provisions of Rule 434 and 424(b). The information included in such Term Sheet that was omitted from such registration statement at the time it became effective but that is deemed part of such registration statement at the time it became effective is referred to as "Rule 434 Information." Each prospectus used before such Rule 424(b) prospectus has been filed and any prospectus that omitted the Rule 434 Information, in each case that was used after such effectiveness and prior to the execution and delivery of this Agreement, is herein called a "preliminary prospectus." Such registration statement, including the exhibits thereto, schedules thereto, if any, and any documents, financial statements and schedules filed by the Company with the Commission under the Securities Exchange Act of 1934, as amended (the "1934 Act"), and so incorporated or deemed to be incorporated by reference (such incorporated documents, financial statements and schedules being herein called the "Incorporated Documents"), at the time it became effective and including the Rule 434 Information is herein called the "Registration Statement." Any related registration statement filed pursuant to Rule 462(b) of the 1933 Act Regulations is herein referred to as the "Rule 462(b) Registration Statement" and after such filing the term "Registration Statement" shall include the Rule 462(b) Registration Statement. The final prospectus, including the prospectus supplement relating to the Securities and the Incorporated Documents, in the form first furnished to the Underwriters for use in connection with the offering of the Securities (as amended, supplemented or replaced and provided to the Underwriters for use in connection with the offering of the Securities if such amendment, supplement or replacement is not required to be filed by the Offerors pursuant to Rule 424(b)) is herein called the "Prospectus." Notwithstanding the foregoing, for purposes of this Agreement any prospectus supplement prepared or filed with respect to an offering pursuant to the Registration Statement of a series of securities other than the Securities shall not be deemed to have supplemented the Prospectus. If Rule 434 is relied on, the term "Prospectus" shall refer to the preliminary prospectus dated January 8, 1999 together with the Term Sheet and all references in this Agreement to the date of the Prospectus shall mean the date of the Term Sheet. For purposes of this Agreement, all references to the Registration Statement, any preliminary prospectus, the Prospectus or any Term Sheet or any amendment or supplement to any of the foregoing shall be deemed to include the copy filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval system ("EDGAR"). SECTION 1. Representations and Warranties. The Offerors jointly and ------------------------------ severally represent and warrant to each of the Underwriters as follows: (a) The Incorporated Documents, when they were filed or became effective (or, if an amendment with respect to any such Incorporated Document was filed or became effective, when such amendment was filed or became effective) with the Commission, as the case may be, complied in all material respects with the requirements 3

of the 1934 Act and the rules and regulations of the Commission under the 1934 Act (the "1934 Act Regulations"), and any Incorporated Documents filed subsequent to the date hereof and prior to the termination of the offering of the Securities, will, when they are filed with the Commission, comply in all material respects with the requirements of the 1934 Act and the 1934 Act Regulations; no such Incorporated Document, when it was filed or became effective (or, if an amendment with respect to any such Incorporated Document was filed or became effective, when such amendment was filed or became effective) with the Commission, contained, and no Incorporated Document filed subsequent to the date hereof and prior to the termination of the offering of the Securities will contain, an untrue statement of a material fact or omitted, or will omit, to state a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were or will be made, not misleading. (b) Each preliminary prospectus relating to the Securities filed as part of the Registration Statement as originally filed or as part of any amendment thereto, or filed pursuant to Rule 424 of the 1933 Act Regulations, when so filed, and the Registration Statement, at the time it became effective, complied in all material respects with the provisions of the 1933 Act and the 1933 Act Regulations; at the date hereof, at the Closing Time (as defined herein) and at the Delivery Date (as defined herein), if applicable, the Registration Statement and the Prospectus, and any supplement or amendment thereto relating to the Securities, comply and will comply in all material respects with the provisions of the 1933 Act and the 1933 Act Regulations; and the Registration Statement and the Prospectus, and any such supplement or amendment thereto relating to the Securities, at all such times did not 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, in the light of the circumstances under which they were made, not misleading; except that this representation and warranty does not apply to statements or omissions in the Registration Statement, the Prospectus or any preliminary prospectus, or any amendment or supplement thereto, made in reliance upon information furnished to the Company in writing by any Underwriter expressly for use therein or to those parts of the Registration Statement that constitute the Trustee's Statement of Eligibility on Form T-1 under the 1939 Act (the "Form T-1"). There is no contract or document of a character required to be described in the Registration Statement or the Prospectus or to be filed as an exhibit to the Registration Statement that is not described or filed as required. In the event that the Registration Statement (including any prospectus filed as part of the Registration Statement), any preliminary prospectus or the Prospectus or any amendment or supplement to any of the foregoing was or is filed electronically pursuant to EDGAR, then the Registration Statement (including any prospectus filed as part thereof), such preliminary prospectus, the Prospectus and any such amendment or supplement delivered to the Underwriters for use in connection with the offering of the Securities was or will be, as the case may be, identical (as to content) to the electronically transmitted copy thereof filed with the Commission pursuant to EDGAR, except to the extent permitted by Regulation S-T. (c) This Agreement has been duly authorized by each of the Trust and Occidental and conforms in all material respects to the description thereof in the Prospectus. 4

(d) The Indenture has been duly authorized by Occidental. (e) The Indenture (assuming the due authorization, execution and delivery thereof by the Debt Trustee) is, and the Subordinated Debt Securities (when executed by Occidental and authenticated and issued in accordance with the Indenture and delivered to and paid for by the purchaser thereof) will be, the legal, valid and binding obligations of Occidental, enforceable against Occidental in accordance with their terms, except as such enforceability may be limited by (A) bankruptcy, insolvency, reorganization, moratorium or other similar laws now or hereafter in effect relating to or affecting the enforcement of creditors' rights generally and (B) general principles of equity (regardless of whether such enforcement is considered in a proceeding in equity or at law). The Preferred Securities (when executed by the Trust and authenticated in accordance with the terms of the Declaration and delivered to and paid for by the purchasers thereof) will be entitled to the benefits of the Declaration (subject to the exceptions set forth in the preceding sentence). (f) Occidental and each of Occidental Chemical Holding Corporation, a California corporation, and Occidental Oil and Gas Corporation, a California corporation (each a "Principal Domestic Subsidiary" and collectively the "Principal Domestic Subsidiaries") is a validly existing corporation in good standing under the laws of its state of incorporation. Occidental and each Principal Domestic Subsidiary has full corporate power and authority to own its properties and carry on its business as presently conducted, as described in the Prospectus, and is duly registered or qualified to conduct business, and is in good standing, in each jurisdiction in which it owns or leases property or transacts business and in which such registration or qualification is necessary, except as to jurisdictions where the failure to do so would not have a material adverse effect on Occidental and its subsidiaries, taken as a whole. All of the outstanding capital stock or other securities evidencing equity ownership of each Principal Domestic Subsidiary has been duly and validly authorized and issued and is fully paid and non-assessable, and is owned by Occidental, directly or indirectly through subsidiaries, free and clear of any security interest, claim, lien or encumbrance. There are no outstanding rights, warrants or options to acquire, or instruments convertible into or exchangeable for, any shares of capital stock or other equity interest in any such Principal Domestic Subsidiary, except for rights, warrants or options held by Occidental. (g) Except as contemplated in the Prospectus or reflected therein by the filing of any amendment or supplement thereto or any Incorporated Document, since the date of the most recent consolidated financial statements included or incorporated by reference in the Registration Statement and the Prospectus, unless Occidental has notified the Underwriters as provided in Section 4(d) hereof, there has not been any material adverse change in the consolidated financial condition of the Company and its subsidiaries, taken as a whole. (h) Occidental is not in violation of its Restated Certificate of Incorporation or Bylaws, in each case, as amended. The execution, delivery and performance of this Agreement and the consummation of the transactions contemplated herein (including, without limitation, the issuance and sale of the Preferred Securities, the Preferred 5

Securities Guarantee and the Subordinated Debt Securities) and compliance by the Trust and Occidental with their respective obligations under this Agreement and the Indenture will not conflict with or constitute a breach of or a default (with the passage of time or otherwise) under (A) the Restated Certificate of Incorporation or Bylaws of Occidental, in each case, as amended, or the certificate of trust, as amended (the "Certificate of Trust") of the Trust, (B) any agreement or instrument (which is, individually or in the aggregate, material to Occidental and its subsidiaries, taken as a whole, or the Trust) to which Occidental or the Trust is a party or by which either is bound or (C) any order of any court or governmental agency or authority presently in effect and applicable to Occidental, any Principal Domestic Subsidiary or the Trust. Except for orders, permits and similar authorizations required under the securities or Blue Sky laws of certain jurisdictions, including jurisdictions outside the United States, or required of any securities exchange on which any of the Securities might be listed, no consent, approval, authorization or other order of any regulatory body, administrative agency or other governmental body is legally required for the valid issuance and sale of the Securities. (i) To the best of Occidental's knowledge, the accountants who have audited and reported upon the consolidated financial statements filed with the Commission as part of the Registration Statement and the Prospectus are independent accountants as required by the 1933 Act. The consolidated financial statements included in the Registration Statement and Prospectus, or incorporated therein by reference, fairly present the consolidated financial position and results of operations of the entities to which such statements relate at the respective dates and for the respective periods to which they apply. Such consolidated financial statements have been prepared in accordance with generally accepted accounting principles consistently applied, except as set forth in the Registration Statement and Prospectus. (j) The Preferred Securities Guarantee Agreement has been duly authorized and, at the Closing Time, will have been duly executed by Occidental and (assuming the due authorization, execution and delivery by the Preferred Guarantee Trustee) constitutes the legal, valid and binding agreement of Occidental enforceable against Occidental in accordance with its terms, except as such enforceability may be limited by (A) bankruptcy, insolvency, reorganization, moratorium or other similar laws now or hereafter in effect relating to or affecting the enforcement of creditors' rights generally and (B) general principles of equity (regardless of whether such enforcement is considered in a proceeding in equity or at law). (k) The Preferred Securities, the Subordinated Debt Securities, the Preferred Securities Guarantee, the Declaration and the Indenture will conform in all material respects to the respective statements relating thereto contained in the Prospectus and will be in substantially the respective forms filed or incorporated by reference, as the case may be, as exhibits to the Registration Statement. (l) The Declaration has been duly authorized by the Regular Trustees (as defined in the Declaration), and, at the Closing Time, will have been duly executed and delivered by the Regular Trustees, and assuming due authorization, execution and delivery of the Declaration by the Property Trustee under the Declaration (the "Property 6

Trustee") and the Delaware Trustee under the Declaration (the "Delaware Trustee" and, together with the Regular Trustees and the Property Trustee, the "Trustees"), the Declaration will, at the Closing Time, be a valid and binding obligation of the Regular Trustees, enforceable against the Regular Trustees in accordance with its terms, except as such enforceability may be limited by (A) bankruptcy, insolvency, reorganization, moratorium or other similar laws now or hereafter in effect relating to or affecting the enforcement of creditors' rights generally and (B) general principles of equity (regardless of whether such enforcement is considered in a proceeding in equity or at law), and will conform in all material respects to all statements relating thereto in the Prospectus; and at the Closing Time, the Declaration will have been qualified under the 1939 Act. (m) The Preferred Securities have been duly authorized by the Declaration and, when issued and delivered pursuant to this Agreement against payment of the consideration set forth herein, will be validly issued and (subject to the terms of the Declaration) fully paid and non- assessable undivided beneficial interests in the Trust and will be entitled to the benefits of the Declaration; the issuance of the Preferred Securities is not subject to preemptive or other similar rights; and (subject to the terms of the Declaration) holders of Preferred Securities will be entitled to the same limitation of personal liability under Delaware law as extended to stockholders of private corporations for profit. (n) Additional Certifications. Any certificate signed by any officer or trustee of the Offerors and delivered to the Underwriters or to counsel for the Underwriters in connection with transactions contemplated hereby shall be deemed a representation and warranty by the respective Offeror to the Underwriters as to the matters covered thereby on the date of such certificate. SECTION 2. Sale and Delivery to Underwriters; Closing. ------------------------------------------ (a) Initial Securities. On the basis of the representations and warranties ------------------ herein contained and subject to the terms and conditions herein set forth, the Trust agrees to sell to each Underwriter, severally and not jointly, and each Underwriter, severally and not jointly, agrees to purchase from the Trust, at the price per security set forth in Schedule B, the number of Initial Securities set forth in Schedule A opposite the name of such Underwriter, plus any additional number of Initial Securities which such Underwriter may become obligated to purchase pursuant to the provisions of Section 11 hereof. (b) Option Securities. In addition, on the basis of the representations and ----------------- warranties herein contained and subject to the terms and conditions herein set forth, the Trust hereby grants an option to the Underwriters, severally and not jointly, to purchase up to an additional 1,000,000 Preferred Securities at the price per Preferred Security set forth in Schedule B, less an amount per Preferred Security equal to any distributions declared by the Trust and payable on the Initial Securities but not payable on the Option Securities. The option hereby granted will expire 30 days after the date hereof and may be exercised in whole or in part from time to time only for the purpose of covering over- allotments which may be made in connection with the offering and distribution of the Initial Securities upon notice by the Representatives to the Trust and the Guarantor setting forth the number of Option Securities as to which the several Underwriters are 7

then exercising the option and the time and date of payment and delivery (the "Delivery Date") for such Option Securities. Any such time and a Delivery Date shall be determined by the Representatives, but shall not be later than seven full business days after the exercise of said option, nor in any event prior to the Closing Time, as hereinafter defined. If the option is exercised as to all or any portion of the Option Securities, each of the Underwriters, acting severally and not jointly, will purchase that proportion of the total number of Option Securities then being purchased which the number of Initial Securities set forth in Schedule A opposite the name of such Underwriter bears to the total number of Initial Securities, subject in each case to such adjustments as the Representatives in their discretion shall make to eliminate any sales or purchases of fractional Preferred Securities. (c) Commission. As compensation to the Underwriters for their commitments ---------- hereunder and in view of the fact that the proceeds of the sale of the Securities will be used to purchase the Subordinated Debt Securities of Occidental, Occidental hereby agrees to pay to the Representatives, for the accounts of the several Underwriters, a commission per Preferred Security set forth in Schedule B as compensation to the Underwriters for their commitments under this Agreement. (d) Payment. Payment of the purchase price for, and delivery of ------- certificates for, the Initial Securities shall be made at the offices of Brown & Wood LLP, 10877 Wilshire Boulevard, Los Angeles, California 90024, or at such other place as shall be agreed upon by the Representatives and the Offerors, at 10:00 A.M. (Eastern time) on January 20, 1999 (unless postponed in accordance with the provisions of Section 10), or such other time not later than ten business days after such date as shall be agreed upon by the Representatives and the Offerors (such time and date of payment and delivery being herein called "Closing Time"). In addition, in the event that any or all of the Option Securities are purchased by the Underwriters, payment of the purchase price for, and delivery of certificates for, such Option Securities shall be made at the above-mentioned offices, or at such other place as shall be agreed upon by the Representatives, the Guarantor and the Trust, on each Delivery Date as specified in the notice from the Representatives to the Guarantor and the Trust. Payment shall be made to the Trust by wire transfer of immediately available funds to a bank account designated by the Trust to the Underwriters, against delivery to the Representatives for the respective accounts of the Underwriters of certificates for the Securities to be purchased by them. It is understood that each Underwriter has authorized the Representatives, for its account, to accept delivery of, receipt for, and make payment of the purchase price for, the Initial Securities and the Option Securities, if any, which it has agreed to purchase. Merrill Lynch, individually and not as representative of the Underwriters, may (but shall not be obligated to) make payment of the purchase price for the Initial Securities or the Option Securities, if any, to be purchased by any Underwriter whose funds have not been received by the Closing Time or the Delivery Date, as the case may be, but such payment shall not relieve such Underwriter from its obligations hereunder. At the Closing Time and on each Delivery Date, Occidental will pay, or cause to be paid, the commission payable at such time to the Underwriters under Section 2(c) hereof by wire transfer of immediately available funds to a bank account designated by Merrill Lynch. 8

(e) Denominations; Registration. Certificates for the Initial Securities --------------------------- and the Option Securities, if any, shall be in such denominations and registered in such names as the Representatives may request in writing at least one full business day before the Closing Time or the relevant Delivery Date, as the case may be. The certificates for the Securities will be made available for examination and packaging by the Representatives in The City of New York not later than 10:00 A.M. (Eastern time) on the business day prior to the Closing Time or the relevant Delivery Date, as the case may be. SECTION 3. Foreign Offerings. ----------------- Each Underwriter, severally and not jointly, represents and agrees that (i) it has not solicited, and will not solicit, offers to purchase any of the Securities from, (ii) it has not sold, and will not sell, any of the Securities to, and (iii) it has not distributed, and will not distribute, the Prospectus to, any person or entity in any jurisdiction outside of the United States (collectively "Foreign Offers and Sales") except, in each case, in compliance in all material respects with all applicable laws and, in connection with the initial offering of, or subscription for, any of the Securities, only with the prior written consent of Occidental and in full compliance with any requirements and procedures established by Occidental with respect to any such Foreign Offers and Sales. For the purposes of this paragraph, "United States" means the United States of America, its territories, its possessions (including the Commonwealth of Puerto Rico) and other areas subject to its jurisdiction. In particular and without limiting the generality of the foregoing: (a) Each Underwriter, severally and not jointly, agrees to distribute, in connection with any Foreign Offers and Sales, only those Prospectuses used in connection therewith that have been appropriately "stickered" for use in the jurisdiction in which such Foreign Offers and Sales are to be made.

SECTION 6. Conditions of Underwriters' Obligations. The obligations of the --------------------------------------- several Underwriters hereunder are subject to the accuracy of the representations and warranties of the Offerors contained in Section 1 hereof and the accuracy of the statements made in any certificate furnished by either Offeror pursuant to the provisions hereof, to the performance and observance by the Offerors of all covenants and agreements herein contained on its part to be performed and observed and to the following additional conditions precedent: (a) At the Closing Time, no stop order suspending the effectiveness of the Registration Statement shall have been issued and no proceedings for that purpose shall be instituted or threatened or, to the knowledge of the Offerors or the Underwriters, contemplated by the Commission; no stop order suspending the sale of the Securities in any jurisdiction designated by the Representatives pursuant to Section 4(f) shall have been issued and no proceedings for that purpose shall have been instituted or threatened or, to the knowledge of the Offerors or the Underwriters, shall be contemplated; any request of the Commission for additional information (to be included in the Registration Statement or Prospectus or otherwise) shall have been complied with to the satisfaction of the Representatives.

(b) The Underwriters shall have received an opinion from Robert E.

Each Principal Domestic Subsidiary is validly existing in good standing under the laws of its state of incorporation. (ii) Occidental has full corporate power and corporate authority to enter into and perform its obligations under this Agreement, the Declaration, the Indenture and each of the Guarantee Agreements, to borrow money as contemplated in this Agreement and the Indenture, and to issue, sell and deliver the Subordinated Debt Securities, and to purchase, own and hold the Common Securities issued by the Trust. 14

(iii) This Agreement, the Guarantee Agreements and the Subordinated Debt Securities have been duly authorized, executed and delivered by Occidental. (iv) The Declaration has been duly authorized, executed and delivered by the Guarantor and each of the Regular Trustees. (v) The Indenture has been duly authorized, executed and delivered by Occidental and (assuming the due authorization, execution and delivery of the Indenture by the Debt Trustee) is a valid and binding agreement of Occidental enforceable against Occidental in accordance with its terms, except that such enforceability may be limited by (A) bankruptcy, insolvency, reorganization, moratorium or other similar laws now or hereafter in effect relating to creditors' rights generally and (B) general principles of equity (regardless of whether enforcement is sought in a proceeding in equity or at law). (vi) No consent or approval of any United States governmental authority or other United States person or United States entity is required in connection with the issuance or sale of the Securities other than registration thereof under the 1933 Act, qualification of the Indenture under the 1939 Act, and such registrations or qualifications as may be necessary under the securities or Blue Sky laws of the various United States jurisdictions in which the Securities are to be offered or sold. (vii) The Subordinated Debt Securities have been duly authorized by Occidental and, when executed by Occidental and authenticated by the Debt Trustee in accordance with the terms of the Indenture (assuming the due authorization, execution and delivery of the Indenture by the Debt Trustee) and issued to and paid for by the Trust, will be entitled to the benefits of the Indenture and will be valid and binding obligations of Occidental enforceable against Occidental in accordance with their terms, except that such enforceability may be limited by (A) bankruptcy, insolvency, reorganization, moratorium or other similar laws now or hereafter in effect relating to creditors' rights generally and (B) general principles of equity (regardless of whether such enforcement is sought in a proceeding in equity or at law). (viii) The Registration Statement, including any Rule 462(b) Registration Statement, has become effective under the 1933 Act and the Indenture has been qualified under the 1939 Act, and, to the best of such counsel's knowledge, no stop order suspending the effectiveness of the Registration Statement or any Rule 462(b) Registration Statement has been issued and no proceedings for that purpose have been instituted or are pending or contemplated. (ix) The execution, delivery and performance of this Agreement, the Declaration, the Preferred Securities, the Common Securities, the Indenture, the Subordinated Debt Securities, the Guarantee Agreements and the Guarantees and the consummation of the transactions contemplated herein and therein and compliance by the Offerors with their respective obligations hereunder and 15

thereunder will not conflict with or constitute a breach of or a default (with the passage of time or otherwise) under (A) the Restated Certificate of Incorporation or Bylaws of Occidental, in each case, as amended, or the Declaration or the Certificate of Trust, (B) any statute, law or regulation to which Occidental or any Principal Domestic Subsidiary or any of their respective properties may be subject or (C) any judgment, decree or order, known to such counsel, after reasonable inquiry, of any court or governmental agency or authority entered in any proceeding to which Occidental or any Principal Domestic Subsidiary was or is now a party or by which it is bound, except that such counsel may state that the opinion set forth in clause (B) of this paragraph (ix) is limited to those statutes, laws or regulations in effect on the date of such opinion which, in such counsel's experience, are normally applicable to transactions of the type contemplated by this Agreement and that such counsel expresses no opinion as to the securities or Blue Sky laws of the various jurisdictions in which the Securities are to be offered. (x) The Registration Statement and the Rule 462(b) Registration Statement as of their respective effective dates, and the Prospectus, as of its date, including each Incorporated Document when such Incorporated Document was filed or became effective, or if any such Incorporated Document was amended, when such amendment was filed or became effective, appeared on their face to be appropriately responsive in all material respects to the applicable requirements of the 1933 Act or the 1934 Act, as the case may be, except that in each case such counsel need not express an opinion as to the financial statements and schedules and other financial data included or incorporated by reference therein or as to the Form T-1. (xi) The statements in the Prospectus under the captions "Certain Terms of the Subordinated Notes," "Description of Senior Debt Securities," "Description of Subordinated Debt Securities," "Description of Preferred Securities Guarantees" and "Relationship Among Preferred Securities, Preferred Securities Guarantees and Subordinated Debt Securities Held by Each Trust," insofar as they purport to summarize certain provisions of documents specifically referred to therein, are in all material respects accurate summaries of such provisions. (xii) Except as set forth in the Prospectus (including the Incorporated Documents), there is not pending or, to the knowledge of such counsel, after reasonable inquiry, threatened any action, suit or proceeding against Occidental or any of its subsidiaries before or by any court or governmental agency or body, which is likely (to the extent not covered by insurance) to have a material adverse effect on the consolidated financial condition of Occidental and its subsidiaries, taken as a whole. (xiii) All of the issued and outstanding Common Securities of the Trust are directly owned of record by the Guarantor free and clear of any security interest, mortgage, pledge, lien, encumbrance, claim or equity, except for the 16

restrictions on transfer set forth in the Declaration and except that such counsel may state that in rendering the opinion set forth in this paragraph (xiii) regarding security interests, mortgages, pledges, liens, encumbrances, claims and equities on the Common Securities of the Trust such counsel has not undertaken any independent investigation of the public record. (xiv) To the best of such counsel's knowledge, after reasonable inquiry, there is no contract or document of a character required to be described in the Registration Statement or the Prospectus or to be filed as an exhibit to the Registration Statement that is not described or filed as required. (xv) To the best of such counsel's knowledge, after reasonable inquiry, Occidental is not in violation of its Restated Certificate of Incorporation or Bylaws, in each case, as amended. (xvi) To the best of such counsel's knowledge, after reasonable inquiry, the execution and delivery of this Agreement and the Indenture by Occidental, the issuance and sale of the Subordinated Debt Securities and the performance by Occidental of its obligations under this Agreement and the Indenture will not conflict with or constitute a breach of or a default (with the passage of time or otherwise) under any agreement or instrument that is, individually or in the aggregate, material to Occidental and its subsidiaries, taken as a whole, and to which Occidental is a party or by which it is bound. (xvii) The Declaration and the Preferred Securities Guarantee have been duly qualified under the 1939 Act. (xviii) The Preferred Securities Guarantee Agreement has been duly authorized, executed and delivered by the Guarantor and, assuming due authorization, execution and delivery by The Bank of New York, constitutes a valid and binding obligation of the Guarantor, enforceable against the Guarantor in accordance with its terms, except as may be subject to or limited by (a) bankruptcy, insolvency, reorganization, moratorium or other similar laws now or hereafter in effect affecting creditors' rights generally, (b) the effect of general principles of equity, including, without limitation, concepts of materiality, reasonableness, good faith and fair dealing and the possible unavailability of specific performance or injunctive relief, regardless of whether considered in a proceeding in equity or at law, (c) requirements that a claim with respect to the Preferred Securities Guarantee denominated other than in United States dollars (or a judgment denominated other than in United States dollars in respect of such claim) be converted into United States dollars at a rate of exchange prevailing on a date determined pursuant to applicable law, (d) governmental authority to limit, delay or prohibit the making of payments outside the United States or in a foreign currency, composite currency or currency unit, and (e) the effect of general rules of contract law that limit the enforceability of provisions requiring indemnification of a party for liability for its own action or inaction to the extent 17

the action or inaction involves gross negligence, recklessness, willful misconduct or unlawful conduct. In rendering such opinion such counsel may state that with respect to certain matters he has relied upon advice of other counsel employed by Occidental who are more familiar with such matters. In addition, such counsel shall state that he has participated in conferences with officers and other representatives of the Offerors, outside counsel for the Offerors, representatives of the independent public accountants for Occidental, representatives of the Underwriters and counsel for the Underwriters, at which conferences the contents of the Registration Statement, the Rule 462(b) Registration Statement and Prospectus and related matters were discussed and, although he is not passing upon, and does not assume any responsibility for the accuracy, completeness or fairness of the statements contained in the Registration Statement, the Rule 462(b) Registration Statement or the Prospectus (other than as set forth in paragraph (xi) above) and has not made any independent check or verification thereof, on the basis of the foregoing, nothing has come to such counsel's attention that leads him to believe that either the Registration Statement (including the Incorporated Documents) at the time such Registration Statement became effective, (or if an amendment to the Registration Statement or an Annual Report on Form 10-K has been filed by Occidental with the Commission subsequent to the effectiveness of the Registration Statement and prior to the date of such statement, then at the time such amendment became effective or at the time of the most recent such filing (to the extent deemed to be incorporated by reference therein), as the case may be) or the Rule 462(b) Registration Statement at the time such Rule 462(b) Registration Statement became effective, 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, or that the Prospectus (including the Incorporated Documents) as of its date and as of the Closing Time contained or contains an untrue statement of a material fact or omitted or omits to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, except that such counsel need express no opinion with respect to the financial statements, schedules and other financial data included or incorporated by reference in the Registration Statement, the Rule 462(b) Registration Statement or Prospectus or with respect to the Form T-1.

omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; (ii) against any and all loss, liability, claim, damage and expense whatsoever (including, subject to the limitations set forth in subsection (c) below, the reasonable fees and disbursements of counsel chosen by the Underwriters), as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever, insofar as such loss, liability, claim, damage or expense arises out of any such untrue statement or omission, or any such alleged untrue statement or omission, if such settlement is effected with the written consent of Occidental; and (iii) against any and all expense whatsoever (including, subject to the limitations set forth in subsection (c) below, the reasonable fees and disbursements of counsel chosen by the Underwriters), as incurred, reasonably incurred in investigating, preparing or defending against any litigation, or investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever, based upon any such untrue statement or omission, or any such alleged untrue statement or omission; provided, however, that this indemnity shall not apply to any loss, liability, claim, damage or expense (A) to the extent arising out of or based upon any untrue statement or omission or alleged untrue statement or omission made in reliance upon the Form T-1 under the 1939 Act filed as an exhibit to the Registration Statement; or (B) to the extent arising out of any untrue statement or omission or alleged untrue statement or omission in the Prospectus, if such untrue statement or alleged untrue statement or omission or alleged omission is corrected in an amendment or supplement to the Prospectus and if, having previously been furnished by or on behalf of the Trust or Occidental with copies of the Prospectus, as so amended or supplemented, such Underwriter thereafter failed to deliver such Prospectus, as so amended or supplemented, prior to or concurrently with the sale of a Security or Securities to the person asserting such loss, liability, claim, damage or expense who purchased such Security or Securities that are the subject thereof from such Underwriter; or (C) as to which such Underwriter may be required to indemnify the Trust or Occidental pursuant to the provisions of subsection (c) of this Section 7; or (D) if such loss, liability, claim, damage or expense is covered by any other written agreement between the Trust or Occidental and such Underwriter pertaining to the sale of the Securities pursuant to which such Underwriter may be required to indemnify the Offerors for such loss, liability, claim, damage or expense. (b) Indemnification of the Trust. Occidental agrees to indemnify the ---------------------------- Trust against all loss, liability, claim, damage and expense whatsoever, as due from the Trust under Section 7(a) hereunder. (c) Indemnification of the Offerors. Each Underwriter agrees, ------------------------------- severally and not jointly, to indemnify and hold harmless the Offerors, their directors, their trustees, 22

each of their officers who signed the Registration Statement, and each person, if any, who controls the Offerors within the meaning of Section 15 of the 1933 Act against any and all loss, liability, claim, damage and expense described in the indemnity contained in subsection (a) of this Section 7, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement or the Prospectus in reliance upon and in conformity with written information furnished to the Trust or Occidental by or on behalf of any such Underwriter expressly for use in the Registration Statement or the Prospectus. (d) General. ------- (1) In case any action, suit or proceeding (including any governmental or regulatory investigation or proceeding) shall be brought against any Underwriter or any person controlling such Underwriter, based upon the Registration Statement or the Prospectus and with respect to which indemnity may be sought against the Trust or Occidental pursuant to this Section 7, such Underwriter or controlling person shall promptly notify Occidental in writing, and Occidental shall assume the defense thereof, including the employment of counsel and payment of all expenses. Any such Underwriter or any such controlling person shall have the right to employ separate counsel in any such action, suit or proceeding and to participate in the defense thereof, but the fees and expenses of such separate counsel shall be at the expense of such Underwriter or such controlling person, unless (A) the employment of such counsel shall have been specifically authorized in writing by Occidental, (B) Occidental shall have failed to assume the defense and employ counsel or (C) the named parties to any such action, suit or proceeding (including any impleaded parties) shall include both such Underwriter or such controlling person and the Trust or Occidental, and such Underwriter or such controlling person shall have been advised by such counsel that there may be one or more legal defenses available to it that are different from, or additional to, those available to the Trust or Occidental (in which case, if such Underwriter or such controlling person notifies Occidental in writing that it elects to employ separate counsel at the expense of Occidental, Occidental shall not have the right to assume the defense of such action, suit or proceeding on behalf of such Underwriter or such controlling person, it being understood, however, that Occidental shall not, in connection with any one such action or separate but substantially similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the reasonable fees and expenses of more than one separate firm of attorneys (in addition to any local counsel) for all such Underwriters and all such controlling persons, which firm shall be designated in writing by the Representatives, on behalf of all such Underwriters and all such controlling persons). (2) In case any action, suit or proceeding (including any governmental or regulatory investigation or proceeding) shall be brought 23

against the Trust or Occidental, any of their directors, officers or trustees, or any person controlling either Occidental or the Trust, with respect to which indemnity may be sought against any Underwriter pursuant to this Section 7, such Underwriter shall have the rights and duties given to Occidental by subsection (d)(i) of this Section 7, and Occidental, the Trust, their directors, officers and trustees and any such controlling person shall have the rights and duties given to the Underwriters by subsection (d)(i) of this Section 7. SECTION 8. Contribution. ------------ In order to provide for just and equitable contribution in circumstances in which the indemnity agreement provided for in Section 7 hereof is for any reason held to be unenforceable by the indemnified parties, although applicable in accordance with its terms, each indemnified party shall contribute to the aggregate losses, liabilities, claims, damages and expenses of the nature contemplated by said indemnity agreement incurred by such indemnified party, as incurred, (i) in such proportion as is appropriate to reflect the relative benefits received by Occidental, on the one hand, and each of the Underwriters, on the other hand, from the offering of the Securities or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Trust and Occidental, on the one hand, and of the Underwriters, on the other hand, in connection with the statements or omissions that resulted in such losses, liabilities, claims, damages and expenses. The relative benefits received by Occidental, on the one hand, and the Underwriters, on the other hand, shall be deemed to be in the same proportions as the total net proceeds from the sale of the Securities (before deducting expenses) received by the Trust as set forth on the cover page of the Prospectus, or, if Rule 434 is used, the corresponding location on the Term Sheet, on the one hand, and the total underwriting discounts and commissions received by each Underwriter, on the other hand, bear to the total purchase price to the public of the Securities as set forth on such cover page. The relative fault of the Trust or Occidental, on the one hand, and the Underwriters, on the other hand, 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 Occidental or by the Underwriters and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Underwriters' respective obligations to contribute pursuant to this Section 8 are several in proportion to the respective principal amount of Securities they have purchased hereunder, and not joint. Notwithstanding the provisions of this Section 8, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages that 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 1933 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 8, each person, if any, who controls an Underwriter within the meaning of Section 15 of the 1933 Act shall have the same rights to contribution as such Underwriter, and each director of Occidental, each officer of Occidental who signed the Registration Statement, each trustee of the Trust and each person, if any, who controls 24

Occidental or the Trust within the meaning of Section 15 of the 1933 Act shall have the same rights to contribution as Occidental. Any party entitled to contribution hereunder will, promptly after receipt of notice of commencement of any action, suit or proceeding against such party in respect of which a claim for contribution may be made against another party or parties under this Section 8, notify such party or parties from whom contribution may be sought, but the omission to so notify such party or parties shall not relieve the party or parties from whom contribution may be sought from any other obligation it or they may have otherwise than under this Section 8. SECTION 9. Representations, Warranties and Agreements to Survive Delivery. -------------------------------------------------------------- All representations, warranties and agreements contained in this Agreement or in certificates of officers or trustees of the Offerors submitted pursuant hereto, shall remain operative and in full force and effect, regardless of any investigation made by or on behalf of any Underwriter or controlling person, or by or on behalf of the Offerors, and shall survive delivery of the Securities to the Underwriters. SECTION 10. TERMINATION OF AGREEMENT. ------------------------ (a) The Representatives may terminate this Agreement, by notice to the Offerors, at any time at or prior to the Closing Time if (i) between the date hereof and the Closing Date, there shall have been any material adverse change in the consolidated financial condition of the Trust or of Occidental and its subsidiaries, taken as a whole, (ii) there shall have occurred any material adverse change in the financial markets in the United States or any outbreak or escalation of hostilities or other national or international calamity or crisis, the effect of which shall be such as to make it, in the reasonable judgment of the Representatives, impracticable to market or to enforce contracts for sale of the Securities, (iii) trading in any securities of Occidental shall have been suspended by the Commission or a national securities exchange in the United States, or if trading generally on the New York Stock Exchange shall have been suspended, or minimum or maximum prices for trading shall have been fixed, or maximum ranges for prices for securities shall have been required, by said exchange or by order of the Commission or any other governmental authority, or if a banking moratorium shall have been declared by either Federal or New York authorities, (iv) since the date of this Agreement, any nationally recognized securities rating agency in the United States shall have publicly announced that it has (A) placed the Securities or Occidental's long-term debt generally on what is commonly termed a "watch list" for possible downgrading or (B) downgraded the Securities or Occidental's long- term debt generally, or (v) the Offerors shall have failed to furnish or cause to be furnished the certificates, opinions or letters referred to in Section 6 hereof. (b) If this Agreement is terminated pursuant to this Section, such termination shall be without liability of any party to any other party except as provided in Section 5 hereof. SECTION 11. Default by One or More of the Underwriters. If one or more of ------------------------------------------ the Underwriters shall fail at Closing Time or a Delivery Date to purchase the Securities which it or they are obligated to purchase under this Agreement (the "Defaulted Securities"), the Representatives shall have the right, within 24 hours thereafter, to make arrangements for one or 25

more of the non-defaulting Underwriters, or any other underwriters, to purchase all, but not less than all, of the Defaulted Securities in such amounts as may be agreed upon and upon the terms herein set forth; if, however, the Representatives shall not have completed such arrangements within such 24-hour period, then: (a) if the number of Defaulted Securities does not exceed 10% of the number of Securities to be purchased on such date pursuant to this Agreement, each of the non-defaulting Underwriters shall be obligated, severally and not jointly, to purchase the full amount thereof in the proportions that their respective underwriting obligations hereunder bear to the underwriting obligations of all non-defaulting Underwriters, or (b) if the number of Defaulted Securities exceeds 10% of the number of Securities to be purchased on such date pursuant to this Agreement, this Agreement or, with respect to any Delivery Date which occurs after the Closing Time, the obligation of the Underwriters to purchase and of the Offerors to sell the Option Securities to be purchased and sold on such Delivery Date shall terminate without liability on the part of any non-defaulting Underwriter. No action taken pursuant to this Section shall relieve any defaulting Underwriter from liability in respect of its default. In the event of any such default which does not result in a termination of this Agreement, or, in the case of a Delivery Date which is after the Closing Time, which does not result in a termination of the obligation of the Underwriters to purchase and the Trust to sell the relevant Option Securities, as the case may be, either the Representatives or the Offerors shall have the right to postpone Closing Time or the relevant Delivery Date, as the case may be, for a period not exceeding seven days in order to effect any required changes in the Registration Statement or Prospectus or in any other documents or arrangements. As used herein, the term "Underwriter" includes any person substituted for an Underwriter under this Section 11. SECTION 12. Notices. All notices and other communications hereunder shall ------- be in writing and shall be deemed to have been duly given if delivered, mailed or transmitted by any standard form of telecommunication. Notices to the Underwriters shall be directed to them care of Merrill Lynch at 10877 Wilshire Boulevard, Suite 1900, Los Angeles, California 90024, attention of Harry T. McMahon III; notices to the Trust and Occidental shall be directed to them at 10889 Wilshire Boulevard, Los Angeles, California 90024, attention of Vice President and Treasurer. SECTION 13. Parties. This Agreement shall inure to the benefit of and be ------- binding upon the Underwriters and the Trust and Occidental and their respective successors. Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any person, firm or corporation, other than the Underwriters and the Trust and Occidental and their respective successors and the controlling persons and officers, directors and trustees referred to in Sections 7 and 8 and their heirs and legal representatives, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision herein contained. This Agreement and all conditions and provisions hereof are intended to be for the sole and exclusive benefit of the Underwriters and the Trust and Occidental and their respective successors, and said controlling persons and officers, directors and trustees and their heirs and legal 26

representatives, and for the benefit of no other person, firm or corporation. No purchaser of Securities from any Underwriter shall be deemed to be a successor by reason merely of such purchase. SECTION 14. GOVERNING LAW AND TIME. This Agreement shall be governed by and ---------------------- construed in accordance with the laws of the State of New York including, without limitation, Section 5-1401 of the New York General Obligations Law. Except as otherwise set forth herein, specified times of day refer to New York City time. SECTION 15. Effect of Headings.

Exhibit A 1. The statements in the Prospectus under the captions "Certain Terms of the Preferred Securities" and "Description of Preferred Securities," insofar as they constitute summaries of legal matters or documents, have been reviewed by us and are accurate in all material respects. 2. The Trust is not an "investment company" within the meaning of the 1940 Act. 3. The Trust has been duly created and is validly existing in good standing as a business trust under the Delaware Act; all filings required under the laws of the State of Delaware with respect to the creation and valid existence of the Trust as a business trust have been made; under the Delaware Act and the Declaration, the Trust has the business trust power and authority to (x) own property and conduct its business, all as described in the Prospectus, (y) enter into and perform its obligations under the Underwriting Agreement, and (z) issue and perform its obligations under the Preferred Securities and the Common Securities. 4. Assuming the Declaration has been duly authorized, executed and delivered by the Trustees and the Company, the Declaration is a valid and binding obligation of the Company and the Regular Trustees, enforceable against the Company and the Regular Trustees, in accordance with its terms, except to the extent that (x) enforcement thereof may be limited by (i) bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance or other similar laws now or hereafter in effect relating to creditors' rights generally and (ii) general principles of equity (regardless of whether enforceability is considered in a proceeding at law or in equity) and (y) the rights to indemnity and contribution contained therein may be limited by applicable law or the public policy underlying such laws. 5. Under the Delaware Act and the Declaration, the execution and delivery by the Trust of the Underwriting Agreement, and the performance by the Trust of its obligations thereunder, have been duly authorized by all necessary business trust action on the part of the Trust; and the Underwriting Agreement has been duly executed by the Trust. 6. The Common Securities have been duly authorized for issuance by the Declaration and, when issued and delivered pursuant to the Common Securities Subscription Agreement, will be validly issued and represent undivided beneficial interests in the assets of the Trust; and under the Delaware Act and the Declaration, the issuance of the Common Securities is not subject to preemptive rights. 7. The Preferred Securities have been duly authorized for issuance by the Declaration and, when issued, executed and authenticated in accordance with the Declaration and delivered and paid for in accordance with the Underwriting Agreement, will be validly issued, and (subject to the qualifications set forth herein) represent fully paid and non-assessable undivided beneficial interests in the assets of the Trust; the holders of the Preferred Securities, in their capacity as such, will be entitled to the same limitation of personal liability extended to stockholders of private corporations for profit organized under the General Corporation Law of the State of Delaware; and under the Delaware Act and the Declaration, the issuance of the Preferred Securities is not subject to preemptive rights. We note that the Preferred Security A-1

holders will be subject to the withholding provisions of Section 11.4 of the Declaration and may be required to make payment or provide indemnity or security as set forth in the Declaration. 8. The issuance and sale by the Trust of the Preferred Securities and the Common Securities, the execution, delivery and performance by the Trust of the Underwriting Agreement, the consummation of the transactions contemplated therein, and compliance by the Trust with its obligations thereunder will not violate any of the provisions of the Certificate of Trust or the Declaration or Applicable Law. As used in this opinion, "Applicable Law" shall mean those laws, rules and regulations of the State of Delaware that, in our experience, are normally applicable to transactions of the type contemplated by the Underwriting Agreement (other than state securities laws, as to which we express no opinion) but without our having made any special investigation with respect to any other laws, rules or regulations. 9. No authorization, approval, consent or order of any Delaware court or governmental authority or agency is required to be obtained by the Trust under Applicable Law in connection with the issuance and sale of the Common Securities and the Preferred Securities or the purchase by the Trust of the Subordinated Debt Securities except such as have been obtained and such as may be required by state securities laws, as to which such we express no opinion. 10. The Trust will be classified as a grantor trust and not as an association taxable as a corporation for United States federal income tax purposes. 11. The statements in the Prospectus under the caption "Certain United States Federal Income Tax Consequences", insofar as they constitute summaries of legal matters, have been reviewed by us and are accurate in all material respects.

In particular, the Trust shall not and the Trustees (including the Property Trustee) shall cause the Trust not to: (i) invest any proceeds received by the Trust from holding the Subordinated Notes, but shall distribute all such proceeds to Holders of Securities pursuant to the terms of this Declaration and of the Securities; (ii) acquire any assets other than the Subordinated Notes and any cash proceeds received with respect thereto; (iii) possess Trust property for other than a Trust purpose; (iv) make any loans or incur any indebtedness other than loans represented by the Subordinated Notes; (v) possess any power or otherwise act in such a way as to vary the assets of the Trust or the terms of the Securities in any way whatsoever; (vi) issue any securities or other evidences of beneficial ownership of, or beneficial interest in, the Trust other than the Securities; or (vii) other than as expressly provided in this Declaration and Exhibit A hereto, (A) direct the time, method and place of exercising any trust or power conferred upon the Subordinated Notes Trustee with respect to the Subordinated Notes, (B) waive any past default that is waivable under Section 513 of the Indenture, (C) exercise any right to rescind or annul any declaration that the principal of all the Subordinated Notes shall be due and payable or (D) consent to any amendment, modification or termination of the Indenture or the Subordinated Notes, where such consent shall be required, unless the Trust shall have received an opinion of counsel to the effect that such modification will not cause more than an insubstantial risk that for United States federal income tax purposes the Trust will not be classified as a grantor trust. Section 3.8 Powers and Duties of the Property Trustee. ----------------------------------------- (a) The legal title to the Subordinated Notes shall be owned by and held of record in the name of the Property Trustee for the benefit of the Trust and the Holders of the Securities. The right, title and interest of the Property Trustee to the Subordinated Notes shall vest automatically in each Person who may hereafter be appointed as Property Trustee as set forth in Section 5.6. Such vesting and cessation of title shall be effective whether or not conveyancing documents have been executed and delivered. (b) The Property Trustee shall not transfer its right, title and interest in the Subordinated Notes to the Regular Trustees or to the Delaware Trustee (if the Property Trustee does not also act as Delaware Trustee). 15

(c) The Property Trustee shall: (i) establish and maintain a segregated noninterest bearing bank account (the "Property Trustee Account") in the name of and under the exclusive control of the Property Trustee on behalf of the Trust and the Holders of the Securities and, upon the receipt of payments of funds made in respect of the Subordinated Notes held by the Property Trustee, deposit such funds into the Property Trustee Account and make payments to the Holders of the Preferred Securities and the Common Securities from the Property Trustee Account in accordance with Section 6.1. Funds in the Property Trustee Account shall be held uninvested until disbursed in accordance with this Declaration. The Property Trustee Account shall be an account which is maintained with a banking institution the rating on whose long term unsecured indebtedness is at least equal to the rating assigned to the Preferred Securities by a "nationally recognized statistical rating organization", as that term is defined for purposes of Rule 436(g)(2) under the Securities Act; (ii) engage in such ministerial activities as shall be necessary or appropriate to effect the redemption of the Preferred Securities and the Common Securities to the extent the Subordinated Notes are redeemed or mature; and (iii) upon notice of distribution issued by the Regular Trustees in accordance with the terms of the Preferred Securities and the Common Securities, engage in such ministerial activities as shall be necessary or appropriate to effect the distribution of the Subordinated Notes to Holders of Securities upon the Sponsor's election to dissolve the Trust in accordance with Section 8.1(a)(v). (d) The Property Trustee shall take all actions and perform such duties as may be specifically required of the Property Trustee pursuant to the terms of the Securities and this Declaration. (e) The Property Trustee shall have the power to take any Legal Action which arises out of or in connection with an Event of Default or the Property Trustee's duties and obligations under this Declaration, the Business Trust Act or the Trust Indenture Act. If the Property Trustee fails to enforce its rights under the Subordinated Notes after a Holder of Preferred Securities has made a written request, such Holder may, to the fullest extent permitted by law, institute a legal proceeding against the Subordinated Notes Issuer, to enforce the Property Trustee's rights under the Subordinated Notes, without first instituting any legal proceeding against the Property Trustee or any other person or entity. Notwithstanding the foregoing, if an Event of Default has occurred and is continuing and such event is attributable to the failure of the Subordinated Notes Issuer to pay interest, premium, if any, or principal on the Subordinated Notes on the date such interest, premium, if any, or principal is otherwise payable (or in the case of redemption, on the redemption date), then a Holder of Preferred Securities may directly institute a proceeding for enforcement of payment to such Holder of the principal of, premium, if any, or interest on, the Subordinated Notes having a principal amount equal to the aggregate liquidation amount of the Preferred Securities of such Holder (a "Direct Action"). Notwithstanding any payments made to such Holder of Preferred Securities by the Subordinated Notes Issuer in connection with a Direct Action, the Subordinated Notes Issuer shall remain obligated to pay the principal of, premium, if 16

any, or interest on the Subordinated Notes held by the Trust or the Property Trustee of the Trust, and the Subordinated Notes Issuer shall be subrogated to the rights of the Holder of such Preferred Securities with respect to payments on the Preferred Securities. Except as provided in the preceding sentences and in the Preferred Securities Guarantee, the Holders of Preferred Securities will not be able to exercise directly any other remedy available to the holders of the Subordinated Notes. (f) No resignation of the Property Trustee shall be effective unless either: (i) the Trust has been completely liquidated and the proceeds of the liquidation distributed to the Holders of Securities pursuant to the terms of the Securities; or (ii) a Successor Property Trustee has been appointed and accepted that appointment in accordance with Section 5.6. (g) The Property Trustee shall have the legal power to exercise all of the rights, powers and privileges of a holder of Subordinated Notes under the Indenture and, if an Event of Default occurs and is continuing, the Property Trustee shall, for the benefit of Holders of the Securities, enforce its rights as holder of the Subordinated Notes subject to the rights of the Holders pursuant to the terms of such Securities and this Declaration. (h) The Property Trustee may authorize one or more Persons (each, a "Paying Agent") to pay Distributions, redemption payments or liquidation payments on behalf of the Trust with respect to the Preferred Securities and any such Paying Agent shall comply with (S) 317(b) of the Trust Indenture Act. Any Paying Agent may be removed by the Property Trustee at any time and a successor Paying Agent or additional Paying Agents may be appointed at any time by the Property Trustee. (i) Subject to this Section 3.8, the Property Trustee shall have none of the powers or the authority of the Regular Trustees set forth in Section 3.6. (j) The Property Trustee must exercise the powers set forth in this Section 3.8 in a manner which is consistent with the purposes, functions and characterization for United States federal income tax purposes of the Trust set forth in Section 3.3 and the Property Trustee shall not take any action which is inconsistent with or contrary to the purposes, functions and characterization for United States federal income tax purposes of the Trust set out in Section 3.3.

In case an Event of Default has occurred (that has not been cured or waived pursuant to Section 2.6), the Property Trustee shall exercise such of the rights and powers vested in it by this Declaration, and use the same degree of care and skill in their exercise or use, as a prudent person would exercise or use under the circumstances in the conduct of his or her own affairs; (b) no provision of this Declaration shall be construed to relieve the Property Trustee from liability for its own negligent action, its own negligent failure to act, or its own willful misconduct, except that: (i) this Subsection shall not be construed to limit Subsection (a) of this Section; (ii) the Property Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer of the Property Trustee, unless it shall be proved that the Property Trustee was negligent in ascertaining the pertinent facts; (iii) the Property Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with the direction of the Holders of not less than a Majority in liquidation amount of the Securities at the time outstanding relating to the time, method and place of conducting any proceeding for any remedy available to the Property Trustee, or exercising any trust or power conferred upon the Property Trustee under this Declaration including, without limitation, with respect to the Securities; and (iv) no provision of this Declaration shall require the Property Trustee to expend or risk its own funds or otherwise incur financial liability in the performance of any of its duties hereunder or in the exercise of any of its rights or powers, if it shall have reasonable ground for believing that the repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it.

(ii) so long as a Delaware Trustee is required pursuant to Section 5.1, no such resignation of the Trustee that acts as the Delaware Trustee shall be effective until a Successor Delaware Trustee has been appointed and has accepted such appointment by instrument executed by such Successor Delaware Trustee and delivered to the Trust, the Sponsor and the resigning Delaware Trustee. (d) The Holders of the Common Securities shall use their best efforts to promptly appoint a Successor Delaware Trustee (so long as a Delaware Trustee is required pursuant to Section 5.1) or Successor Property Trustee, as the case may be, if the Property Trustee or the Delaware Trustee delivers an instrument of resignation in accordance with this Section 5.6. (e) If no Successor Property Trustee or Successor Delaware Trustee shall have been appointed and accepted appointment as provided in this Section 5.6 within 60 days after delivery of an instrument of resignation or removal, the Property Trustee or Delaware Trustee resigning or being removed may petition any court of competent jurisdiction for appointment of a Successor Property Trustee or Successor Delaware Trustee. Such court may thereupon after such notice, if any, as it may deem proper and prescribe, appoint a Successor Property Trustee or Successor Delaware Trustee, as the case may be. Section 5.7 Vacancies Among Trustees. ------------------------ If a Trustee ceases to hold office for any reason and the number of Trustees is not reduced pursuant to Section 5.1, or if the number of Trustees is increased pursuant to Section 5.1, a vacancy shall occur. A resolution certifying the existence of such vacancy by a majority of the Regular Trustees shall be conclusive evidence of the existence of such vacancy. The vacancy shall be filled with a Trustee appointed in accordance with Section 5.6. Section 5.8 Effect of Vacancies. ------------------- The death, resignation, retirement, removal, bankruptcy, dissolution, liquidation, incompetence or incapacity to perform the duties of a Trustee, or any one of them, shall not operate to annul the Trust. Whenever a vacancy in the number of Regular Trustees shall occur, until such vacancy is filled by the appointment of a Regular Trustee in accordance with Section 5.6, the Regular Trustees in office, regardless of their number, shall have all the powers granted to the Regular Trustees and shall discharge all the duties imposed upon the Regular Trustees by this Declaration. Section 5.9 Meetings. -------- Meetings of the Regular Trustees shall be held from time to time upon the call of any Regular Trustee. Regular meetings of the Regular Trustees may be held at a time and place fixed by resolution of the Regular Trustees. Notice of any in-person meetings of the Regular Trustees shall be hand delivered or otherwise delivered in writing (including by facsimile, with a hard copy by overnight courier) not less than 48 hours before such meeting. Notice of any telephonic meetings of the Regular Trustees or any committee thereof shall be hand delivered or otherwise delivered in writing (including by facsimile, with a hard copy by overnight courier) not less than 24 hours before a meeting. Notices shall contain a brief statement of the time, place and anticipated purposes of the meeting. The presence (whether in person or by telephone) of a 27

Regular Trustee at a meeting shall constitute a waiver of notice of such meeting except where a Regular Trustee attends a meeting for the express purpose of objecting to the transaction of any activity on the ground that the meeting has not been lawfully called or convened. Unless provided otherwise in this Declaration, any action of the Regular Trustees may be taken at a meeting by vote of a majority of the Regular Trustees present (whether in person or by telephone) and eligible to vote with respect to such matter, provided that a Quorum is present, or without a meeting by the unanimous written consent of the Regular Trustees. Section 5.10 Delegation of Power. ------------------- (a) Any Regular Trustee may, by power of attorney consistent with applicable law, delegate to any other natural person over the age of 21 his or her power for the purpose of executing any documents contemplated in Section 3.6 including any registration statement or amendment thereto filed with the Commission or making any other governmental filing. (b) The Regular Trustees shall have power to delegate from time to time to such of their number or to officers of the Trust the doing of such things and the execution of such instruments either in the name of the Trust or the names of the Regular Trustees or otherwise as the Regular Trustees may deem expedient, to the extent such delegation is not prohibited by applicable law or contrary to the provisions of the Trust, as set forth herein. Section 5.11 Merger, Conversion, Consolidation or Succession to Business. ----------------------------------------------------------- Any corporation into which the Property Trustee or the Delaware Trustee, as the case may be, may be merged or converted or with which either may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Property Trustee or the Delaware Trustee, as the case may be, shall be bound by this Declaration, or any corporation succeeding to all or substantially all the corporate trust business of the Property Trustee or the Delaware Trustee, as the case may be, shall be the successor of the Property Trustee or the Delaware Trustee, as the case may be, 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. ARTICLE VI DISTRIBUTIONS Section 6.1 Distributions. ------------- Holders shall receive Distributions in accordance with the applicable terms of the relevant Holder's Securities. Distributions shall be made on the Preferred Securities and the Common Securities in accordance with the preferences set forth in their respective terms. If and to the extent that the Subordinated Notes Issuer makes a payment of interest (including Additional Interest (as defined in the Indenture)), premium, if any, and principal on the Subordinated Notes held by the Property Trustee (the amount of any such payment being a "Payment Amount"), the Property Trustee shall and is directed, to the extent funds are available for that purpose, to make a distribution (a "Distribution") of the Payment Amount to Holders. In 28

the event the Sponsor shall defer any payment of principal, premium, if any, or interest on the Subordinated Notes, the Trust shall, in like manner, defer payments of Distributions on the Securities, and additional Distributions shall accrue on such Securities for so long as the payment of principal, premium, if any, or interest on the Subordinated Notes is deferred. ARTICLE VII ISSUANCE OF SECURITIES Section 7.1 General Provisions Regarding Securities. --------------------------------------- (a) The Regular Trustees shall, on behalf of the Trust, issue one class of preferred securities representing undivided beneficial interests in the assets of the Trust having such terms as are set forth in Exhibit A and incorporated herein by reference (the "Preferred Securities"), and one class of common securities representing undivided beneficial interests in the assets of the Trust having such terms as are set forth in Exhibit A and incorporated herein by reference (the "Common Securities"). The Trust shall have no securities or other interests in the assets of the Trust other than the Preferred Securities and the Common Securities; (b) the Certificates shall be signed on behalf of the Trust by the Regular Trustees (or if there are more than two Regular Trustees by any two of the Regular Trustees). Such signatures may be the manual or facsimile signatures of the present or any future Regular Trustee. Typographical and other minor errors or defects in any such reproduction of any such signature shall not affect the validity of any Certificate. In case any Regular Trustee of the Trust who shall have signed any of the Certificates shall cease to be such Regular Trustee before the Certificate so signed shall be delivered by the Trust, such Certificate nevertheless may be delivered as though the person who signed such Certificate had not ceased to be such Regular Trustee; and any Certificate may be signed on behalf of the Trust by such persons who shall at the actual date of execution of such Security, be the Regular Trustees of the Trust, although at the date of the execution and delivery of the Declaration any such person was not such a Regular Trustee. Certificates shall be printed, lithographed or engraved or may be produced in any other manner as is reasonably acceptable to the Regular Trustees, as evidenced by their execution thereof, and may have such letters, numbers or other marks of identification or designation and such legends or endorsements as the Regular Trustees may deem appropriate, or as may be required to comply with any law or with any rule or regulation of any stock exchange on which Securities may be listed, or to conform to usage. A Preferred Security shall not be valid until authenticated by the manual signature of an authorized signatory of the Property Trustee. The signature shall be conclusive evidence that the Preferred Security has been authenticated under this Declaration. Upon a written order of the Trust signed by one Regular Trustee, the Property Trustee shall authenticate the Preferred Securities for original issue. The Property Trustee may appoint an authenticating agent acceptable to the Trust to authenticate Preferred Securities. An authenticating agent may authenticate Preferred Securities whenever the Property Trustee may do so. Each reference in this Declaration to authentication by the Property Trustee includes authentication by such agent. An authenticating agent has the same rights as the Property Trustee to deal with the Trust or an Affiliate; 29

(c) the consideration received by the Trust for the issuance of the Securities shall constitute a contribution to the capital of the Trust and shall not constitute a loan to the Trust; (d) upon issuance of the Securities as provided in this Declaration, the Securities so issued shall be deemed to be validly issued, fully paid and nonassessable; and (e) every Person, by virtue of having become a Holder or a Preferred Security Beneficial Owner in accordance with the terms of this Declaration, shall be deemed to have expressly assented and agreed to the terms of, and shall be bound by this Declaration. ARTICLE VIII DISSOLUTION AND TERMINATION OF TRUST Section 8.1 Dissolution and Termination of Trust. ------------------------------------ (a) The Trust shall dissolve and its affairs shall be wound up, upon the earliest to occur of the following: (i) upon the bankruptcy of the Sponsor or the Holder of the Common Securities; (ii) upon the filing of a certificate of dissolution or its equivalent with respect to the Sponsor, the filing of a certificate of cancellation with respect to the Trust upon the consent (other than in connection with a dissolution of the Trust pursuant to clause (v) of this Section 8.1(a)) of the Holders of at least a Majority in liquidation amount of the Securities, voting together as a single class, to file such certificate of cancellation, or the revocation of the charter of the Sponsor or the Holder of the Common Securities and the expiration of 90 days after the date of revocation without a reinstatement thereof; (iii) upon the entry of a decree of judicial dissolution of the Sponsor or the Trust or the Holder of the Common Securities; (iv) when all of the Securities shall have been called for redemption and the amounts necessary for redemption thereof shall have been paid to the Holders in accordance with the terms of the Securities; (v) upon the election by the Sponsor, effective upon notice to the Trust, the Property Trustee and the Delaware Trustee, to dissolve the Trust in accordance with the terms of the Securities and all of the Subordinated Notes held by the Property Trustee shall have been distributed to the Holders of Securities in exchange for all of the Securities; (vi) upon the written direction to the Property Trustee from the Sponsor at any time to terminate the Trust and, after satisfaction of liabilities to creditors of the Trust as provided by applicable law, the distribution of Subordinated Notes to Holders in exchange for the Securities, subject to the Regular Trustees' receipt of an opinion of 30

counsel experienced in such matters to the effect that the Holders of the Preferred Securities will not recognize any income, gain or loss for United States federal income tax purposes as a result of the dissolution of the Trust and such distribution to Holders; or (vii) before the issuance of any Securities, with the consent of all of the Regular Trustees and the Sponsor; and (b) As soon as is practicable after the occurrence of an event referred to in Section 8.1(a) or dissolution pursuant to Section 3.14 and upon the completion of the winding up of the Trust, one of the Regular Trustees (each Regular Trustee being hereby authorized to take such action) shall file a certificate of cancellation with the Secretary of State of the State of Delaware terminating the Trust. (c) The provisions of Section 3.9 and Article X shall survive the termination of the Trust. ARTICLE IX TRANSFER OF INTERESTS Section 9.1 Transfer of Securities. ---------------------- (a) Securities may only be transferred, in whole or in part, in accordance with the terms and conditions set forth in this Declaration and in the terms of the Securities. Any transfer or purported transfer of any Security not made in accordance with this Declaration shall be null and void; (b) subject to this Article IX, Preferred Securities shall be freely transferable; and (c) subject to this Article IX, the Sponsor and any Related Party may only transfer Common Securities to the Sponsor or a Related Party of the Sponsor; provided that, any such transfer shall not violate the Securities Act and is subject to the condition precedent that the transferor obtain the written opinion of counsel experienced in such matters that such transfer would not cause more than an insubstantial risk that: (i) the Trust would not be classified for United States federal income tax purposes as a grantor trust; and (ii) the Trust would be an Investment Company required to register under the Investment Company Act or the transferee would become an Investment Company required to register under the Investment Company Act. (d) Each Common Security that bears or is required to bear the legend set forth in this Section 9.1(d) shall be subject to the restrictions on transfer provided in the legend set forth in this Section 9.1(d), unless such restrictions on transfer shall be waived by the written consent of the Regular Trustees, and the Holder of each such Common Security, by such security holder's acceptance thereof, agrees to be bound by such restrictions on transfer. As used in this 31

Section 9.1(d) and in Section 9.1(c), the term "transfer" encompasses any sale, pledge, transfer or other disposition of any such Common Security. Any certificate evidencing a Common Security shall bear a legend in substantially the following form, unless otherwise agreed by the Regular Trustees (with written notice thereof to the Property Trustee): THE SECURITY EVIDENCED HEREBY HAS NOT BEEN REGISTERED UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD UNLESS SUCH OFFER AND SALE ARE REGISTERED UNDER OR ARE EXEMPT FROM REGISTRATION UNDER THE SECURITIES ACT. THE TRANSFER OF THE SECURITY EVIDENCED HEREBY IS ALSO SUBJECT TO THE RESTRICTIONS SET FORTH IN THE DECLARATION REFERRED TO BELOW. Section 9.2 Transfer of Certificates. ------------------------ (a) The Regular Trustees shall provide for the registration of Certificates and of transfers of Certificates, which will be effected without charge but only upon payment (with such indemnity as the Regular Trustees may require) in respect of any tax or other government charges which may be imposed in relation to it. Upon surrender for registration of transfer of any Certificate, the Regular Trustees shall cause one or more new Certificates to be issued in the name of the designated transferee or transferees. Every Certificate surrendered for registration of transfer shall be accompanied by a written instrument of transfer in form satisfactory to the Regular Trustees duly executed by the Holder or such Holder's attorney duly authorized in writing. Each Certificate surrendered for registration of transfer shall be canceled by the Regular Trustees. A transferee of a Certificate shall be entitled to the rights and subject to the obligations of a Holder hereunder upon the receipt by such transferee of a Certificate. By acceptance of a Certificate, each transferee shall be deemed to have agreed to be bound by this Declaration and the documents incorporated by reference herein. (b) Notwithstanding any other provisions of this Declaration, a Global Certificate may not be transferred as a whole, except by the Clearing Agency to a nominee of the Clearing Agency or by the Clearing Agency or any such nominee to a successor Clearing Agency or a nominee of such successor Clearing Agency. Section 9.3 Deemed Security Holders. ----------------------- The Trustees may treat the Person in whose name any Certificate shall be registered on the books and records of the Trust as the sole holder of such Certificate and of the Securities represented by such Certificate for purposes of receiving Distributions and for all other purposes whatsoever and, accordingly, shall not be bound to recognize any equitable or other claim to or interest in such Certificate or in the Securities represented by such Certificate on the part of any Person, whether or not the Trustees shall have actual or other notice thereof. 32

Section 9.4 Book Entry Interests. -------------------- (a) So long as Preferred Securities are eligible for book entry settlement with the Clearing Agency or unless otherwise required by law, all Preferred Securities that are so eligible may be represented by one or more, fully registered, global Preferred Security Certificates (each a "Global Certificate"), to be delivered to DTC, the initial Clearing Agency, by, or on behalf of, the Trust. Such Global Certificates shall initially be registered on the books and records of the Trust in the name of Cede & Co., the nominee of DTC, and no Preferred Security Beneficial Owner will receive a definitive Preferred Security Certificate representing such Preferred Security Beneficial Owner's interests in such Global Certificates, except as provided in Section 9.7. The transfer and exchange of beneficial interests in any such Security in global form shall be effected through the Clearing Agency in accordance with this Declaration and the procedures of the Clearing Agency therefor. (b) Except as provided below, Beneficial Owners of a Preferred Security in global form shall not be entitled to have certificates registered in their names, will not receive or be entitled to receive physical delivery of certificates in definitive form and will not be considered Holder of such Preferred Security in global form. (c) Any Global Certificate may be endorsed with or have incorporated in the text thereof such legends or recitals or changes not inconsistent with the provisions of this Declaration as may be required by the Clearing Agency, by any national securities exchange or by the National Association of Securities Dealers, Inc. as may be required to comply with any applicable law or any regulation thereunder or with the rules and regulations of any securities exchange or interdealer quotation system upon which the Preferred Securities may be listed or traded or to conform with any usage with respect thereto, or to indicate any special limitations or restrictions to which any particular Preferred Securities are subject. (d) Unless and until definitive, fully registered Preferred Security Certificates (the "Definitive Preferred Security Certificates") have been issued to the Preferred Security Beneficial Owners pursuant to Section 9.7: (i) the provisions of this Section 9.4 shall be in full force and effect with respect to such Preferred Securities; (ii) the Trust and the Trustees shall be entitled to deal with the Clearing Agency for all purposes of this Declaration (including the payment of Distributions on the Global Certificates and receiving approvals, votes or consents hereunder) as the Holder of the Preferred Securities and the sole holder of the Global Certificates and shall have no obligation to the Preferred Security Beneficial Owners; (iii) to the extent that the provisions of this Section 9.4 conflict with any other provisions of this Declaration, the provisions of this Section 9.4 shall control; and (iv) the rights of the Beneficial Owners of Preferred Securities in global form shall be exercised only through the Clearing Agency and shall be limited to those established by law and agreements between such Preferred Security Beneficial Owners and the Clearing Agency and/or the Clearing Agency Participants. The Clearing Agency 33

will make book entry transfers among the Clearing Agency Participants and receive and transmit payments of Distributions on the Global Certificates to such Clearing Agency Participants. DTC will make book entry transfers among the Clearing Agency Participants, provided, that solely for the purposes of determining whether the Holders of the requisite amount of Preferred Securities have voted on any matter provided for in this Declaration, so long as Definitive Preferred Security Certificates have not been issued, the Trustees may conclusively rely on, and shall be protected in relying on, any written instrument (including a proxy) delivered to the Trustees by the Clearing Agency setting forth the Preferred Securities Beneficial Owners' votes or assigning the right to vote on any matter to any other Persons either in whole or in part. Notwithstanding any other provisions of this Declaration (other than the provisions set forth in this Section 9.4(d)), a Preferred Security in global form may not be transferred as a whole except by the Clearing Agency to a nominee of the Clearing Agency or by a nominee of the Clearing Agency to the Clearing Agency or another nominee to a successor Clearing Agency or a nominee of such successor Clearing Agency. Section 9.5 Notices to Clearing Agency. -------------------------- Whenever a notice or other communication to the Preferred Security Holders is required under this Declaration, unless and until Definitive Preferred Security Certificates shall have been issued to the Preferred Security Beneficial Owners pursuant to Section 9.7, the Trustees shall give all such notices and communications, specified herein to be given to the Preferred Security Holders, to the Clearing Agency, and shall have no notice obligations to the Preferred Security Beneficial Owners. Section 9.6 Appointment of Successor Clearing Agency. ---------------------------------------- If any Clearing Agency notifies the Trust that it is unwilling or unable to continue its services as securities depositary with respect to the Preferred Securities if such Clearing Agency ceases to perform such services, or if at any time such Clearing Agency ceases to be a clearing agency registered as such under the Exchange Act when such Clearing Agency is required to be so registered to act as such depositary, then the Regular Trustees may, in their sole discretion, appoint a successor Clearing Agency with respect to such Preferred Securities. Section 9.7 Definitive Preferred Security Certificates Under Certain -------------------------------------------------------- Circumstances. - ------------- If: (a) a Clearing Agency notifies the Trust that it is unwilling or unable to continue its services as securities depositary with respect to the Preferred Securities, if such Clearing Agency ceases to perform such services, or if at any time such Clearing Agency ceases to be a clearing agency registered as such under the Exchange Act when such Clearing Agency is required to be so registered to act as such depositary, and a successor Clearing Agency is not appointed within 90 days after such discontinuance pursuant to Section 9.6; or 34

(b) the Regular Trustees (with the consent of the Sponsor) in their sole discretion determine that the Preferred Securities in global form shall be exchanged for certificated Preferred Securities; then: (i) Definitive Preferred Security Certificates shall be prepared by the Regular Trustees on behalf of the Trust with respect to such Preferred Securities; and (ii) upon surrender of the Global Certificates by the Clearing Agency, accompanied by registration instructions, the Regular Trustees shall cause Definitive Preferred Security Certificates to be delivered to Preferred Security Beneficial Owners of such Preferred Securities in accordance with the instructions of the Clearing Agency. Neither the Trustees nor the Trust shall be liable for any delay in delivery of such instructions and each of them may conclusively rely on and shall be protected in relying on, said instructions of the Clearing Agency. The Definitive Preferred Security Certificates shall be printed, lithographed or engraved or may be produced in any other manner as is reasonably acceptable to the Regular Trustees, as evidenced by their execution thereof, and may have such letters, numbers or other marks of identification or designation and such legends or endorsements as the Regular Trustees may deem appropriate, or as may be required to comply with any law or with any rule or regulation made pursuant thereto or with any rule or regulation of any stock exchange on which Preferred Securities may be listed, or to conform to usage. At such time as all interests in a Preferred Security in global form have been redeemed, exchanged, repurchased or canceled, such Preferred Security in global form shall be, upon receipt thereof, canceled by the Trust in accordance with standing procedures and instructions of the Clearing Agency. Section 9.8 Mutilated, Destroyed, Lost or Stolen Certificates. ------------------------------------------------- If: (a) any mutilated Certificates should be surrendered to the Regular Trustees, or if the Regular Trustees shall receive evidence to their satisfaction of the destruction, loss or theft of any Certificate; and (b) there shall be delivered to the Property Trustee or the Regular Trustees such security or indemnity as may be required by them to keep each of them harmless, then: in the absence of notice that such Certificate shall have been acquired by a bona fide purchaser, the Property Trustee or any Regular Trustee on behalf of the Trust shall execute and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or stolen Certificate, a new Certificate of like denomination. In connection with the issuance of any new Certificate under this Section 9.8, the Property Trustee or the Regular Trustees may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection 35

therewith. Any duplicate Certificate issued pursuant to this Section shall constitute conclusive evidence of an ownership interest in the relevant Securities, as if originally issued, whether or not the lost, stolen or destroyed Certificate shall be found at any time. ARTICLE X LIMITATION OF LIABILITY OF HOLDERS OF SECURITIES, TRUSTEES OR OTHERS Section 10.1 Liability. --------- (a) Except as expressly set forth in this Declaration, the Preferred Securities Guarantee, the Common Securities Guarantee and the terms of the Securities, the Sponsor shall not be: (i) personally liable for the return of any portion of the capital contributions (or any return thereon) of the Holders of the Securities, which shall be made solely from assets of the Trust; or (ii) be required to pay to the Trust or to any Holder of Securities any deficit upon dissolution of the Trust or otherwise. (b) Pursuant to (S) 3803(a) of the Business Trust Act, the Holders of the Securities, in their capacity as such, shall be entitled to the same limitation of personal liability extended to stockholders of private corporations for profit organized under the General Corporation Law of the State of Delaware. Section 10.2 Exculpation. ----------- (a) No Indemnified Person shall be liable, responsible or accountable in damages or otherwise to the Trust or any Covered Person for any loss, damage or claim incurred by reason of any act or omission performed or omitted by such Indemnified Person in good faith on behalf of the Trust and in a manner such Indemnified Person reasonably believed to be within the scope of the authority conferred on such Indemnified Person by this Declaration or by law, except that an Indemnified Person shall be liable for any such loss, damage or claim incurred by reason of such Indemnified Person's negligence (or, in the case of the Property Trustee, except as otherwise set forth in Section 3.9) or willful misconduct with respect to such acts or omissions. (b) An Indemnified Person shall be fully protected in relying in good faith upon the records of the Trust and upon such information, opinions, reports or statements presented to the Trust by any Person as to matters the Indemnified Person reasonably believes are within such other Person's professional or expert competence and who has been selected with reasonable care by or on behalf of the Trust, including information, opinions, reports or statements as to the value and amount of the assets, liabilities, profits, losses, or any other facts pertinent to the existence and amount of assets from which Distributions to Holders of Securities might properly be paid. 36

Section 10.3 Fiduciary Duty. -------------- (a) To the extent that, at law or in equity, an Indemnified Person has duties (including fiduciary duties) and liabilities relating thereto to the Trust or to any other Covered Person, an Indemnified Person acting under this Declaration shall not be liable to the Trust or to any other Covered Person for its good faith reliance on the provisions of this Declaration. The provisions of this Declaration, to the extent that they restrict the duties and liabilities of an Indemnified Person otherwise existing at law or in equity (other than duties imposed on the Property Trustee under the Trust Indenture Act), are agreed by the parties hereto to replace such other duties and liabilities of such Indemnified Person; (b) Unless otherwise expressly provided herein: (i) whenever a conflict of interest exists or arises between an Indemnified Person and any Covered Persons; or (ii) whenever this Declaration or any other agreement contemplated herein or therein provide that an Indemnified Person shall act in a manner that is, or provides terms that are, fair and reasonable to the Trust or any Holder of Securities, the Indemnified Person shall resolve such conflict of interest, take such action or provide such terms, considering in each case the relative interest of each party (including its own interest) to such conflict, agreement, transaction or situation and the benefits and burdens relating to such interests, any customary or accepted industry practices, and any applicable generally accepted accounting practices or principles. In the absence of bad faith by the Indemnified Person, the resolution, action or term so made, taken or provided by the Indemnified Person shall not constitute a breach of this Declaration or any other agreement contemplated herein or of any duty or obligation of the Indemnified Person at law or in equity or otherwise. (c) Whenever in this Declaration an Indemnified Person is permitted or required to make a decision: (i) in its "discretion" or under a grant of similar authority, the Indemnified Person shall be entitled to consider such interests and factors as it desires, including its own interests, and shall have no duty or obligation to give any consideration to any interest of or factors affecting the Trust or any other Person; or (ii) in its "good faith" or under another express standard, the Indemnified Person shall act under such express standard and shall not be subject to any other or different standard imposed by this Declaration or by applicable law. Section 10.4 Indemnification. --------------- (a) The Sponsor shall indemnify each Indemnified Person for, and hold each Indemnified Person harmless against, any loss, liability or expense incurred by such Indemnified Person by reason of any act or omission performed or omitted by such Indemnified Person without negligence or bad faith (or, in case of the Property Trustee, except as set forth in Section 37

3.9) on behalf of the Trust and in a manner such Indemnified Person reasonably believed to be within the scope of authority conferred on such Indemnified Person by this Declaration; (b) reasonable expenses (including reasonable legal fees and expenses) incurred by an Indemnified Person in defending any claim, demand, action, suit or proceeding shall, from time to time, be advanced by the Sponsor prior to the final disposition of such claim, demand, action, suit or proceeding upon receipt by the Sponsor of an undertaking by or on behalf of the Indemnified Person to repay such amount if it shall be determined that the Indemnified Person is not entitled to be indemnified as authorized in Section 10.4(a); and (c) the provisions of this Section 10.4 shall survive the termination of this Declaration or resignation or removal of any Trustee. Section 10.5 Outside Businesses. ------------------ Any Covered Person, the Sponsor, the Delaware Trustee and the Property Trustee (subject to Section 5.3(c)) may engage in or possess an interest in other business ventures of any nature or description, independently or with others, similar or dissimilar to the business of the Trust, and the Trust and the Holders of Securities shall have no rights by virtue of this Declaration in and to such independent ventures or the income or profits derived therefrom, and the pursuit of any such venture, even if competitive with the business of the Trust, shall not be deemed wrongful or improper. No Covered Person, the Sponsor, the Delaware Trustee, or the Property Trustee shall be obligated to present any particular investment or other opportunity to the Trust even if such opportunity is of a character that, if presented to the Trust, could be taken by the Trust, and any Covered Person, the Sponsor, the Delaware Trustee and the Property Trustee shall have the right to take for its own account (individually or as a partner or fiduciary) or to recommend to others any such particular investment or other opportunity. Any Covered Person, the Delaware Trustee and the Property Trustee may engage or be interested in any financial or other transaction with the Sponsor or any Affiliate of the Sponsor, or may act as depositary for, trustee or agent for, or act on any committee or body of holders of, securities or other obligations of the Sponsor or its Affiliates.

Section 11.2 Certain Accounting Matters. -------------------------- (a) At all times during the existence of the Trust, the Trust shall keep, or cause to be kept, full books of account, records and supporting documents, which shall reflect in reasonable detail, each transaction of the Trust. The books of account shall be maintained on the accrual method of accounting, in accordance with generally accepted accounting principles, consistently 38

applied. The Trust shall use the accrual method of accounting for United States federal income tax purposes.

(b) The Trust shall cause to be duly prepared and delivered to each of the Holders of Securities, any annual United States federal income tax information statement, required by the Code, containing such information with regard to the Securities held by each Holder as is required by the Code and the Treasury Regulations. Notwithstanding any right under the Code to deliver any such statement at a later date, the Trust shall endeavor to deliver all such statements within 30 days after the end of each Fiscal Year of the Trust. (c) The Trust shall cause to be duly prepared and filed with the appropriate taxing authority, an annual United States federal income tax return, on a Form 1041 or such other form required by United States federal income tax law, and any other annual income tax returns required to be filed by the Trust on behalf of the Trust with any state or local taxing authority. Section 11.3 Banking. ------- The Trust shall maintain one or more bank accounts in the name and for the sole benefit of the Trust; provided, however, that all payments of funds in respect of the Subordinated Notes held by the Property Trustee shall be made directly to the Property Trustee Account and no other funds of the Trust shall be deposited in the Property Trustee Account. The sole signatories for such accounts shall be designated by the Regular Trustees; provided, however, that the Property Trustee shall designate the signatories for the Property Trustee Account. Section 11.4 Withholding. ----------- The Trust shall comply with all withholding requirements under United States federal, state and local law.

To the extent that the Trust is required to withhold and pay over any amounts to any authority with respect to distributions or allocations to any Holder, the amount withheld shall be deemed to be a distribution in the amount of the withholding to the Holder.

EXHIBIT A TERMS OF 8.16% TRUST ORIGINATED PREFERRED SECURITIES 8.16% TRUST ORIGINATED COMMON SECURITIES Pursuant to Section 7.1 of the Amended and Restated Declaration of Trust, dated as of January 20, 1999 (as amended from time to time, the "Declaration"), the designation, rights, privileges, restrictions, preferences and other terms and provisions of the Preferred Securities and the Common Securities are set out below (each capitalized term used but not defined herein has the meaning set forth in the Declaration or, if not defined in such Declaration, as defined in the Prospectus referred to below): 1. Designation and Number. ---------------------- a. Preferred Securities. 21,000,000 Preferred Securities of the -------------------- Trust with an aggregate liquidation amount with respect to the assets of the Trust of Five Hundred Twenty-Five Million Dollars ($525,000,000), and a liquidation amount with respect to the assets of the Trust of $25 per Preferred Security, are hereby designated for the purposes of identification only as "8.16% Trust Originated Preferred Securities" (the "Preferred Securities"). The Preferred Security Certificates evidencing the Preferred Securities shall be substantially in the form attached hereto as Annex I, with such changes and additions thereto or deletions therefrom as may be required by ordinary usage, custom or practice or to conform to the rules of any stock exchange on which the Preferred Securities are listed. b. Common Securities. 649,485 Common Securities of the Trust with an ----------------- aggregate liquidation amount with respect to the assets of the Trust of Sixteen Million Two Hundred Thirty-Seven Thousand One Hundred Twenty-Five Dollars ($16,237,125), and a liquidation amount with respect to the assets of the Trust of $25 per Common Security, are hereby designated for the purposes of identification only as "8.16% Trust Originated Common Securities" (the "Common Securities"). The Common Security Certificates evidencing the Common Securities shall be substantially in the form attached hereto as Annex II, with such changes and additions thereto or deletions therefrom as may be required by ordinary usage, custom or practice. 2. Distributions. ------------- a. Periodic Distributions payable on each Security will be fixed at a rate per annum of 8.16% (the "Coupon Rate") of the stated liquidation amount of $25 per Security, such rate being the rate of interest payable on the Subordinated Notes to be held by the Property Trustee. Distributions in arrears for more than one quarterly period will bear interest thereon at the Coupon Rate (to the extent permitted by applicable law). The term "Distributions" as used in these terms includes such periodic cash distributions and any such interest payable unless otherwise stated. A Distribution is payable only to the extent that payments are made in respect of the Subordinated Notes held by the Property Trustee. The amount of Distributions payable for any period will be computed for any full quarterly Distribution period on the basis of a 360-day year of twelve 30-day months, and for any period shorter than a full quarterly Distribution period A-1

for which Distributions are computed, Distributions will be computed on the basis of the actual number of days elapsed in such a 30-day month. b. Distributions on the Securities will be cumulative, will accrue from January 20, 1999 and will be payable quarterly in arrears, on March 31, June 30, September 30 and December 31 of each year, commencing on March 31, 1999, except as otherwise described below. The Subordinated Notes Issuer has the right under the Indenture to defer payments of interest by extending the interest payment period from time to time on the Subordinated Notes for a period not exceeding 20 consecutive quarterly periods (each, an "Extension Period") but not beyond the maturity date of the Subordinated Notes and, as a consequence of such extension, Distributions will also be deferred. Despite such deferral, quarterly Distributions will continue to accrue with interest thereon (to the extent permitted by applicable law) at the Coupon Rate during any such Extension Period. Prior to the termination of any such Extension Period, the Subordinated Notes Issuer may further extend such Extension Period; provided that such Extension Period together with all such previous and further extensions thereof may not exceed 20 consecutive quarterly periods. Payments of accrued Distributions will be payable to Holders as they appear on the books and records of the Trust on the first record date after the end of the Extension Period. Upon the termination of any Extension Period and the payment of all amounts then due, the Subordinated Notes Issuer may commence a new Extension Period, subject to the above requirements. c. Distributions on the Securities will be payable to the Holders thereof as they appear on the books and records of the Trust on the relevant record dates. While the Preferred Securities remain in book entry only form, the relevant record dates shall be one Business Day prior to the relevant payment dates which payment dates correspond to the interest payment dates on the Subordinated Notes. Subject to any applicable laws and regulations and the provisions of the Declaration, each such payment in respect of the Preferred Securities will be made as described under the heading "Certain Terms of the Preferred Securities -- Book-Entry-Only Issuance -- The Depository Trust Company" in the Prospectus Supplement dated January 13, 1999 (the "Prospectus Supplement") to the Prospectus dated January 8, 1999 (as so supplemented the "Prospectus") of the Trust included in the Registration Statement on Form S-3 of the Sponsor, the Trust and certain other business trusts. The relevant record dates for the Common Securities shall be the same record dates as for the Preferred Securities. If the Preferred Securities shall not continue to remain in book entry only form, the relevant record dates for the Preferred Securities, shall conform to the rules of any securities exchange on which the securities are listed and, if none, shall be the 15/th/ day of the last month of each quarterly distribution period, even if that day is not a Business Day. Distributions payable on any Securities that are not punctually paid on any Distribution payment date, as a result of the Subordinated Notes Issuer having failed to make a payment under the Subordinated Notes, will cease to be payable to the Person in whose name such Securities are registered on the relevant record date, and such defaulted Distribution will instead be payable to the Person in whose name such Securities are registered on the special record date or other specified date determined in accordance with the Indenture. If any date on which Distributions are payable on the Securities is not a Business Day, then payment of the Distribution payable on such date will be made on the next succeeding day that is a Business Day (and without any interest or other payment in respect of any such delay) except that, if such Business Day is in the next succeeding calendar year, such payment shall be A-2

made on the immediately preceding Business Day, in each case with the same force and effect as if made on such date. d. In the event that there is any money or other property held by or for the Trust that is not accounted for hereunder, such property shall be distributed Pro Rata (as defined herein) among the Holders of the Securities. 3. Liquidation Distribution Upon Dissolution. ----------------------------------------- In the event of any voluntary or involuntary dissolution, winding-up or termination of the Trust, the Holders of the Securities on the date of the dissolution, winding-up or termination, as the case may be, will be entitled to receive out of the assets of the Trust available for distribution to Holders of Securities, after paying or making reasonable provision to pay all claims and obligations of the Trust in accordance with Section 3808(e) of the Business Trust Act, an amount equal to the aggregate of the stated liquidation amount of $25 per Security plus accrued and unpaid Distributions thereon to the date of payment (such amount being the "Liquidation Distribution"), unless, in connection with such dissolution, winding-up or termination, Subordinated Notes in an aggregate principal amount equal to the aggregate stated liquidation amount of such Securities, with an interest rate equal to the Coupon Rate of, and bearing accrued and unpaid interest in an amount equal to the accrued and unpaid Distributions on, such Securities, shall be distributed on a Pro Rata basis to the Holders of the Securities in exchange for such Securities, after paying or making reasonable provision to pay all claims and obligations of the Trust in accordance with Section 3808(e) of the Business Trust Act. If, upon any such dissolution, the Liquidation Distribution can be paid only in part because the Trust has insufficient assets available to pay in full the aggregate Liquidation Distribution, then the amounts payable directly by the Trust on the Securities shall be paid on a Pro Rata basis. 4. Redemption and Distribution. --------------------------- a. Upon the repayment of the Subordinated Notes in whole or in part, whether at maturity or upon redemption, the proceeds from such repayment or payment shall be simultaneously applied to redeem Securities having an aggregate liquidation amount equal to the aggregate principal amount of the Subordinated Notes so repaid or redeemed, at the redemption price for the Subordinated Notes, payable in cash (the "Redemption Price"). Holders will be given not less than 30 nor more than 60 days notice of such redemption. b. If fewer than all the outstanding Securities are to be so redeemed, the Common Securities and the Preferred Securities will be redeemed Pro Rata and the Preferred Securities to be redeemed will be as described in Paragraph 4(h)(ii) below. c. The Subordinated Notes are redeemable, in whole or in part, at the option of the Subordinated Notes Issuer, on one or more occasions, at any time on or after January 20, 2004, at a redemption price equal to 100% of the principal amount per Subordinated Note, plus, in each case, accrued and unpaid interest thereon at the date of the redemption for the Subordinated Notes. A-3

d. If, at any time, a Tax Event or an Investment Company Event (each as defined below, and each a "Special Event") shall occur and be continuing, the Subordinated Notes Issuer shall have the right, upon not less than 30 nor more than 60 days notice, to redeem the Subordinated Notes in whole or in part, for cash within 90 days following the occurrence of such Special Event, at a redemption price equal to 100% of the principal amount to be redeemed plus any accrued and unpaid interest thereon to the date of such redemption and, following such redemption, Securities with an aggregate liquidation amount equal to the aggregate principal amount of the Subordinated Notes so redeemed shall be redeemed by the Trust at the Redemption Price on a Pro Rata basis in accordance with paragraph 8 hereof. The Common Securities will be redeemed Pro Rata with the Preferred Securities, except that if an Event of Default has occurred and is continuing, the Preferred Securities will have priority over the Common Securities with respect to payment of the Redemption Price. e. The following terms used herein shall be defined as follows: (i) "Investment Company Event" means that the Trust shall have received an opinion of counsel experienced in practice under the Investment Company Act to the effect that, as a result of the occurrence of a change in law or regulation or a change in interpretation or application of law or regulation by any legislative body, court, governmental agency or regulatory authority (a "Change in 1940 Act Law"), there is more than an insubstantial risk that the Trust is or will be considered an Investment Company which is required to be registered under the Investment Company Act, which Change in 1940 Act Law becomes effective on or after the date of the Prospectus Supplement. (ii) "Tax Event" means that the Trust shall have received an opinion of counsel experienced in such matters to the effect that on or after the date of the Prospectus Supplement, as a result of (a) any amendment to, or change (including any announced proposed change) in, the laws (or any regulations thereunder) of the United States or any political subdivision or taxing authority thereof or therein, or (b) any official or administrative pronouncement or action, or judicial decision, interpreting or applying such laws or regulations, where such change or amendment becomes effective, or such pronouncement, action or decision is announced or occurs, in each case on or after the date of the Prospectus Supplement, there is more than an insubstantial risk that (i) the Trust is or will be within 90 days of the date of such opinion, subject to United States federal income tax with respect to interest accrued or received on the Subordinated Notes, (ii) the Trust is, or will be within 90 days of the date of such opinion, subject to more than a minimal amount of other taxes, duties, assessments or other governmental charges, or (iii) interest payable by the Subordinated Notes Issuer to the Trust on the Subordinated Notes is not, or within 90 days of the date of such opinion will not be, deductible, in whole or in part, by the Subordinated Notes Issuer for United States federal income tax purposes. f. The Trust may not redeem fewer than all the outstanding Securities unless all accrued and unpaid Distributions have been paid on all Securities for all quarterly Distribution periods terminating on or before the date of redemption. A-4

g. In the event that the Sponsor makes the election referred to in Section 8.1(a)(v) of the Declaration, the Regular Trustees shall dissolve the Trust and, after paying or making reasonable provision to pay all claims and obligations of the Trust in accordance with Section 3808(e) of the Business Trust Act, cause Subordinated Notes, held by the Property Trustee, having an aggregate stated liquidation amount of, with an interest rate identical to the Coupon Rate of, and accrued and unpaid interest equal to accrued and unpaid Distributions on and having the same record date for payment, as the Securities, to be distributed to the Holders of the Securities in liquidation of such Holders' interests in the Trust on a Pro Rata basis in accordance with paragraph 8 hereof. On and from the date fixed by the Regular Trustees for any distribution of Subordinated Notes and dissolution of the Trust: (i) the Securities will no longer be deemed to be outstanding, (ii) The Depository Trust Company (the "Depository") or its nominee (or any successor Clearing Agency or its nominee), as the record Holder of the Preferred Securities, will receive a registered global certificate or certificates representing the Subordinated Notes to be delivered upon such distribution and (iii) any certificates representing Securities, except for certificates representing Preferred Securities held by the Depository or its nominee (or any successor Clearing Agency or its nominee), will be deemed to represent beneficial interests in the Subordinated Notes having an aggregate principal amount equal to the aggregate stated liquidation amount of, with an interest rate identical to the Coupon Rate of, and accrued and unpaid interest equal to accrued and unpaid Distributions on such Securities until such certificates are presented to the Subordinated Notes Issuer or its agent for transfer or reissue. If the Subordinated Notes are distributed to Holders of the Securities, pursuant to the terms of the Indenture, the Subordinated Notes Issuer will use its best efforts to have the Subordinated Notes listed on the New York Stock Exchange or on such other exchange as the Preferred Securities were listed immediately prior to the distribution of the Subordinated Notes. h. Redemption or Distribution Procedures. ------------------------------------- (i) Notice of any redemption of, or notice of distribution of Subordinated Notes in exchange for the Securities (a "Redemption/Distribution Notice") will be given by the Trust by mail to each Holder of Securities to be redeemed or exchanged not fewer than 30 nor more than 60 days before the date fixed for redemption or exchange thereof which, in the case of a redemption, will be the date fixed for redemption of the Subordinated Notes. For purposes of the calculation of the date of redemption or exchange and the dates on which notices are given pursuant to this paragraph 4(h)(i), a Redemption/Distribution Notice shall be deemed to be given on the day such notice is first mailed, by first-class mail, postage prepaid, to Holders of Securities. Each Redemption/Distribution Notice shall be addressed to the Holders of Securities at the address of each such Holder appearing in the books and records of the Trust. No defect in the Redemption/Distribution Notice or in the mailing of either thereof with respect to any Holder shall affect the validity of the redemption or exchange proceedings with respect to any other Holder. (ii) In the event that fewer than all the outstanding Securities are to be redeemed, the Securities to be redeemed will be redeemed Pro Rata from each Holder of Securities, it being understood that, in respect of Preferred Securities registered in the name of and held of record by the Depository (or any successor Clearing Agency) or any other nominee, the distribution of the proceeds of such redemption will be made to each Clearing Agency A-5

Participant (or person on whose behalf such nominee holds such securities) in accordance with the procedures applied by such agency or nominee. (iii) If Securities are to be redeemed and the Trust gives a Redemption/Distribution Notice which notice may only be issued if the Subordinated Notes are redeemed as set out in this paragraph 4 (which notice will be irrevocable) then (A) while the Preferred Securities are in book entry only form, with respect to the Preferred Securities, by 12:00 noon, New York City time, on the redemption date, provided that the Subordinated Notes Issuer has paid the Property Trustee a sufficient amount of cash in connection with the related redemption or maturity of the Subordinated Notes, the Property Trustee will deposit irrevocably with the Depository (or successor Clearing Agency) funds sufficient to pay the Redemption Price with respect to the Preferred Securities and will give the Depository irrevocable instructions and authority to pay the Redemption Price to the Holders of the Preferred Securities, and (B) if the Preferred Securities are issued in definitive form, with respect to the Preferred Securities, and with respect to the Common Securities, provided that the Subordinated Notes Issuer has paid the Property Trustee a sufficient amount of cash in connection with the related redemption or maturity of the Subordinated Notes, the Property Trustee will pay the Redemption Price to the Holders of such Securities by check mailed to the address of the relevant Holder appearing on the books and records of the Trust on the redemption date. If a Redemption/Distribution Notice shall have been given and funds deposited as required, if applicable, then immediately prior to the close of business on the date of such deposit, or on the redemption date, as applicable, Distributions will cease to accrue on the Securities so called for redemption and all rights of Holders of such Securities so called for redemption will cease, except the right of the Holders of such Securities to receive the Redemption Price, but without interest on such Redemption Price. Neither the Regular Trustees nor the Trust shall be required to register or cause to be registered the transfer of any Securities which have been so called for redemption. If any date fixed for redemption of Securities is not a Business Day, then payment of the Redemption Price payable on such date will be made on the next succeeding day that is a Business Day (and without any interest or other payment in respect of any such delay) except that, if such Business Day falls in the next calendar year, such payment will be made on the immediately preceding Business Day, in each case with the same force and effect as if made on such date fixed for redemption. If payment of the Redemption Price in respect of Securities is improperly withheld or refused and not paid either by the Property Trustee or by the Sponsor as guarantor pursuant to the relevant Securities Guarantee, Distributions on such Securities will continue to accrue, from the original redemption date to the actual date of payment, in which case the actual payment date will be considered the date fixed for redemption for purposes of calculating the Redemption Price. (iv) Redemption/Distribution Notices shall be sent by the Regular Trustees on behalf of the Trust to (A) in respect of the Preferred Securities, the Depository or its nominee (or any successor Clearing Agency or its nominee) if the Global Certificates have been issued or if Definitive Preferred Security Certificates have been issued, to the Holder thereof, and (B) in respect of the Common Securities, to the Holder thereof. (v) Subject to the foregoing and applicable law (including, without limitation, United States federal securities laws), provided the acquiror is not the Holder of the Common Securities or the obligor under the Indenture, the Sponsor or any of its subsidiaries may A-6

at any time and from time to time purchase outstanding Preferred Securities by tender, in the open market or by private agreement. 5. Voting Rights Applicable to Preferred Securities. ------------------------------------------------ a. Except as provided under paragraphs 5(b) and 7 and as otherwise required by law and the Declaration, the Holders of the Preferred Securities will have no voting rights. b. Subject to the requirements of the third to last sentence of this paragraph, the Holders of a Majority in liquidation amount of the Preferred Securities, voting separately as a class, may direct the time, method, and place of conducting any proceeding for any remedy available to the Property Trustee, or exercising any trust or power conferred upon the Property Trustee under the Declaration, including (i) directing the time, method, and place of conducting any proceeding for any remedy available to the Subordinated Notes Trustee, or exercising any trust or power conferred on the Subordinated Notes Trustee with respect to the Subordinated Notes, (ii) waiving any past default and its consequences that is waivable under Section 513 of the Indenture, (iii) exercising any right to rescind or annul a declaration that the principal of all the Subordinated Notes shall be due and payable or (iv) consenting to any amendment, modification or termination of the Indenture or the Subordinated Notes where such consent shall be required, provided, however, that where a consent under the Indenture would require the consent or act of the Holders of greater than a majority in principal amount of Subordinated Notes affected thereby (a "Super Majority"), the Property Trustee may only give such consent or take such action at the direction of the Holders of at least the proportion in liquidation amount of the Preferred Securities which the relevant Super Majority represents of the aggregate principal amount of the Subordinated Notes outstanding. The Property Trustee shall not revoke any action previously authorized or approved by a vote of the Holders of the Preferred Securities. Other than with respect to directing the time, method and place of conducting any remedy available to the Property Trustee or the Subordinated Notes Trustee as set forth above, the Property Trustee shall not take any action in accordance with the directions of the Holders of the Preferred Securities under this paragraph unless the Property Trustee has obtained an opinion of counsel to the effect that for the purposes of United States federal income tax the Trust will not be classified as other than a grantor trust on account of such action. If the Property Trustee fails to enforce its rights under the Declaration, any Holder of Preferred Securities may institute a legal proceeding directly against any Person to enforce the Property Trustee's rights under the Declaration, without first instituting a legal proceeding against the Property Trustee or any other Person. Notwithstanding the foregoing, if an Event of Default has occurred and is continuing with respect to the Preferred Securities and such event is attributable to the failure of the Subordinated Notes Issuer to pay interest, premium, if any, or principal on the Subordinated Notes on the date such interest, premium, if any, or principal is otherwise payable (or in the case of redemption, on the redemption date), then a holder of Preferred Securities may institute a Direct Action for enforcement of payment to such holder of the principal of, premium, if any, or interest on, Subordinated Notes having a principal amount equal to the aggregate liquidation amount of the Preferred Securities of such holder on or after the respective due date specified in the Subordinated Notes. Notwithstanding any payments made to such Holder of Preferred Securities by the Subordinated Notes Issuer in connection with a Direct Action, the Subordinated Notes Issuer shall remain obligated to pay the principal of, premium, if any, and interest on the Subordinated Notes held by the Trust or the Property Trustee, and the Subordinated Notes Issuer A-7

shall be subrogated to the rights of the Holder of such Preferred Securities with respect to payments on the Preferred Securities to the extent of any payment made by the Subordinated Notes Issuer to such Holder in any Direct Action. Except as provided in the preceding sentences, the Holders of Preferred Securities will not be able to exercise directly any other remedy available to the holders of the Subordinated Notes. c. Any approval or direction of Holders of Preferred Securities may be given at a separate meeting of Holders of Preferred Securities convened for such purpose, at a meeting of all of the Holders of Securities in the Trust or pursuant to written consent. The Regular Trustees will cause a notice of any meeting at which Holders of Preferred Securities are entitled to vote, or of any matter upon which action by written consent of such Holders is to be taken, to be mailed to each Holder of record of Preferred Securities. Each such notice will include a statement setting forth (i) the date of such meeting or the date by which such action is to be taken, (ii) a description of any resolution proposed for adoption at such meeting on which such Holders are entitled to vote or of such matter upon which written consent is sought and (iii) instructions for the delivery of proxies or consents. d. No vote or consent of the Holders of the Preferred Securities will be required for the Trust to redeem and cancel Preferred Securities or to distribute the Subordinated Notes in accordance with the Declaration and the terms of the Securities. e. Notwithstanding that Holders of Preferred Securities are entitled to vote or consent under any of the circumstances described above, any of the Preferred Securities that are owned by the Sponsor or any Affiliate of the Sponsor shall not be entitled to vote or consent and shall, for purposes of such vote or consent, be treated as if they were not outstanding. 6. Voting Rights With Respect to Common Securities. ----------------------------------------------- a. Except as provided under paragraphs 6(b), 6(c) and 7 and as otherwise required by law and the Declaration, the Holders of the Common Securities will have no voting rights. b. The Holders of the Common Securities are entitled, in accordance with Article V of the Declaration, to vote to appoint, remove or replace any Trustee or to increase or decrease the number of Trustees. c. Subject to Section 2.6 of the Declaration and only after all Events of Default with respect to the Preferred Securities have been cured, waived or otherwise eliminated and subject to the requirements of the second to last sentence of this paragraph, the Holders of a Majority in liquidation amount of the Common Securities, voting separately as a class, may direct the time, method, and place of conducting any proceeding for any remedy available to the Property Trustee, or exercising any trust or power conferred upon the Property Trustee under the Declaration, including (i) directing the time, method, place of conducting any proceeding for any remedy available to the Subordinated Notes Trustee, or exercising any trust or power conferred on the Subordinated Notes Trustee with respect to the Subordinated Notes, (ii) waiving any past default and its consequences that is waivable under Section 513 of the Indenture, or (iii) exercising any right to rescind or annul a declaration that the principal of all the Subordinated A-8

Notes shall be due and payable, provided, however, that where a consent or action under the Indenture would require the consent or act of the Holders of greater than a majority in principal amount of Subordinated Notes affected thereby (a "Super Majority"), the Property Trustee may only give such consent or take such action at the direction of the Holders of at least the proportion in liquidation amount of the Common Securities which the relevant Super Majority represents of the aggregate principal amount of the Subordinated Notes outstanding. Pursuant to this paragraph 6(c), the Property Trustee shall not revoke any action previously authorized or approved by a vote of the Holders of the Common Securities. Other than with respect to directing the time, method and place of conducting any remedy available to the Property Trustee or the Subordinated Notes Trustee as set forth above, the Property Trustee shall not take any action in accordance with the directions of the Holders of the Common Securities under this paragraph unless the Property Trustee has obtained an opinion of counsel to the effect that for the purposes of United States federal income tax the Trust will not be classified as other than a grantor trust on account of such action. If the Property Trustee fails to enforce its rights under the Declaration, any Holder of Common Securities may, to the fullest extent permitted by law, institute a legal proceeding directly against any Person to enforce the Property Trustee's rights under the Declaration, without first instituting a legal proceeding against the Property Trustee or any other Person. Notwithstanding the foregoing, if an Event of Default has occurred and is continuing with respect to the Common Securities and such event is attributable to the failure of the Subordinated Notes Issuer to pay interest or principal on the Subordinated Notes on the date such interest or principal is otherwise payable (or in the case of redemption, on the redemption date), then a holder of Common Securities may institute a proceeding for enforcement of payment to such holder of the principal of, or interest on, Subordinated Notes having a principal amount equal to the aggregate liquidation amount of the Common Securities of such holder on or after the respective due date specified in the Subordinated Notes. d. Any approval or direction of Holders of Common Securities may be given at a separate meeting of Holders of Common Securities convened for such purpose, at a meeting of all of the Holders of Securities in the Trust or pursuant to written consent. The Regular Trustees will cause a notice of any meeting at which Holders of Common Securities are entitled to vote, or of any matter upon which action by written consent of such Holders is to be taken, to be mailed to each Holder of record of Common Securities. Each such notice will include a statement setting forth (i) the date of such meeting or the date by which such action is to be taken, (ii) a description of any resolution proposed for adoption at such meeting on which such Holders are entitled to vote or of such matter upon which written consent is sought and (iii) instructions for the delivery of proxies or consents. e. No vote or consent of the Holders of the Common Securities will be required for the Trust to redeem and cancel Common Securities or to distribute the Subordinated Notes in accordance with the Declaration and the terms of the Securities. 7. Amendments to Declaration and Indenture. --------------------------------------- a. In addition to any requirements under Section 12.1 of the Declaration, if any proposed amendment to the Declaration provides for, or the Regular Trustees otherwise propose to effect, (i) any action that would adversely affect the powers, preferences or special rights of the Securities, whether by way of amendment to the Declaration or otherwise, or (ii) the A-9

dissolution, winding-up or termination of the Trust, other than as described in Section 8.1 or Section 3.14 of the Declaration, then the Holders of outstanding Securities as a class, will be entitled to vote on such amendment or proposal (but not on any other amendment or proposal) and such amendment or proposal shall not be effective except with the approval of the Holders of at least a Majority in liquidation amount of the Securities, voting together as a single class; provided, however, that if any amendment or proposal referred to in clause (i) above would adversely affect only the Preferred Securities or the Common Securities, then only the affected class will be entitled to vote on such amendment or proposal and such amendment or proposal shall not be effective except with the approval of a Majority in liquidation amount of such class of Securities. b. In the event the consent of the Property Trustee as the holder of the Subordinated Notes is required under the Indenture with respect to any amendment, modification or termination of the Indenture or the Subordinated Notes, the Property Trustee shall request the direction of the Holders of the Securities with respect to such amendment, modification or termination and shall vote with respect to such amendment, modification or termination as directed by a Majority in liquidation amount of the Securities voting together as a single class; provided, however, that where a consent under the Indenture would require the consent of the Holders of greater than a majority in aggregate principal amount of the Subordinated Notes (a "Super Majority"), the Property Trustee may only give such consent at the direction of the Holders of at least the proportion in liquidation amount of the Securities which the relevant Super Majority represents of the aggregate principal amount of the Subordinated Notes outstanding; provided, further, that the Property Trustee shall not take any action in accordance with the directions of the Holders of the Securities under this paragraph 7(b) unless the Property Trustee has been furnished an opinion of counsel to the effect that for the purposes of United States federal income tax the Trust will not be classified as other than a grantor trust on account of such action. 8. Pro Rata. -------- A reference in these terms of the Securities to any payment, distribution or treatment as being "Pro Rata" shall mean pro rata to each Holder of Securities according to the aggregate liquidation amount of the Securities held by the relevant Holder in relation to the aggregate liquidation amount of all Securities outstanding unless, in relation to a payment, an Event of Default under the Indenture has occurred and is continuing, in which case any funds available to make such payment shall be paid first to each Holder of the Preferred Securities pro rata according to the aggregate liquidation amount of Preferred Securities held by the relevant Holder relative to the aggregate liquidation amount of all Preferred Securities outstanding, and only after satisfaction of all amounts owed to the Holders of the Preferred Securities, to each Holder of Common Securities pro rata according to the aggregate liquidation amount of Common Securities held by the relevant Holder relative to the aggregate liquidation amount of all Common Securities outstanding. 9. Ranking. ------- The Preferred Securities rank pari passu and payment thereon shall be made Pro Rata with the Common Securities except that, where an Event of Default occurs and is continuing A-10

under the Indenture in respect of the Subordinated Notes held by the Property Trustee, the rights of Holders of the Common Securities to payment in respect of Distributions and payments upon liquidation, redemption and otherwise are subordinated to the rights to payment of the Holders of the Preferred Securities. 10. Acceptance of Securities Guarantee and Indenture. ------------------------------------------------ Each Holder of Preferred Securities and Common Securities, by the acceptance thereof, agrees to the provisions of the Preferred Securities Guarantee and the Common Securities Guarantee, respectively, including the subordination provisions therein and to the provisions of the Indenture. 11.

The Trustee and the Company may assume that such ownership of any Bearer Security continues until (1) another certificate or affidavit bearing a later date issued in respect of the same Bearer Security is produced, (2) such Bearer Security is produced to the Trustee by some other Person, (3) such Bearer Security is surrendered in exchange for a Registered Security or (4) such Bearer Security is no longer Outstanding. The principal amount and serial numbers of Bearer Securities held by any Person, and the date of holding the same, may also be proved in any other manner which the Trustee deems sufficient. (e) Any request, demand, authorization, direction, notice, consent, waiver or other Act of the Holder of any Security shall bind every future Holder of the same Security and the Holder of every Security issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the Trustee or the Company in reliance thereon, whether or not notation of such action is made upon such Security. (f) If the Company shall solicit from the Holders any request, demand, authorization, direction, notice, consent, waiver or other Act, the Company may, at its option, by or pursuant to an Officers' Certificate delivered to the Trustee, fix in advance a record date for the determination of Holders entitled to give such request, demand, authorization, direction, notice, consent, waiver or other Act, but the Company shall have no obligation to do so. Any such record date, if so fixed, may vary from that specified in Section 316(c) of the Trust Indenture Act. If such a record date is fixed, such request, demand, authorization, direction, notice, consent, waiver or other Act may be given before or after such record date, but only the Holders of record at the close of business on such record date shall be deemed to be Holders for the purposes of determining whether Holders of the requisite percentage of Outstanding Securities or Outstanding Securities of a series, as the case may be, have authorized or agreed or consented to such request, demand, authorization, direction, notice, consent, waiver or other Act, and for that purpose the Outstanding Securities or Outstanding Securities of the series, as the case may be, shall be computed as of such record date; provided, that no such authorization, agreement or consent by the Holders on the record date shall be deemed effective, unless such request, demand, authorization, direction, notice, consent, waiver or other Act shall become effective pursuant to the provisions of Clause (a) of this Section 104 not later than six months after the record date. SECTION 105. Notices, Etc., to Trustee and Company. 10

Any request, demand, authorization, direction, notice, consent, waiver or Act of Holders or other document provided or permitted by this Indenture to be made upon, given or furnished to, or filed with, (1) the Trustee by any Holder or by the Company shall be sufficient for every purpose hereunder if made, given, furnished or filed in writing to or with the Trustee at its Corporate Trust Office, Attention: Corporate Trust Trustee Administration, or (2) the Company by the Trustee or by any Holder shall be sufficient for every purpose hereunder (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to the Company addressed to it, Attention: Treasurer, at the address of its principal office specified in the first paragraph of this instrument or at any other address previously furnished in writing to the Trustee by the Company.

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. In case, by reason of the suspension of regular mail service, or by reason of any other cause, it shall be impracticable to give such notice to Holders of Registered Securities by mail, then such notification as shall be made with the approval of the Trustee shall constitute a sufficient notification for every purpose hereunder. In any case where notice to Holders of Registered Securities is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder of a Registered Security shall affect the sufficiency of such notice with respect to 11

other Holders of Registered Securities or the sufficiency of any notice to Holders of Bearer Securities given as provided herein. In case, by reason of the suspension of publication of any Authorized Newspaper or Authorized Newspapers, or by reason of any other cause, it shall be impracticable to publish any notice to Holders of Bearer Securities as provided above, then such notification to Holders of Bearer Securities as shall be given with the approval of the Trustee shall constitute sufficient notice to such Holders for every purpose hereunder. Neither the failure to give notice by publication to Holders of Bearer Securities as provided above, nor any defect in any notice so published, shall affect the sufficiency of any notice to Holders of Registered Securities given as provided herein. SECTION 107. Conflict with Trust Indenture Act. If any provision hereof limits, qualifies or conflicts with the duties imposed by operation of Trust Indenture Act Section 318(c), the imposed duties shall control. SECTION 108. Effect of Headings and Table of Contents. The Article and Section headings herein and the Table of Contents are for convenience only and shall not affect the construction hereof. SECTION 109. Successors and Assigns. All covenants and agreements in this Indenture by the Company shall bind its successors and assigns, whether so expressed or not. SECTION 110. Separability Clause. In case any provision in this Indenture or in the Securities shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby. SECTION 111. Benefits of Indenture. Except as provided in the last paragraph of Section 401, nothing in this Indenture or in the Securities, express or implied, shall give to any Person, other than the parties hereto and their successors hereunder and the Holders of Securities, any benefits or any legal or equitable right, remedy or claim under this Indenture.

There shall be established in one or more Board Resolutions or pursuant to authority granted by one or more Board Resolutions and, subject to Section 303, set forth, or determined in the manner provided, in an Officers' Certificate, or established in one or more indentures supplemental hereto: (1) the title of the Securities of the series (which shall distinguish the Securities of the series from all other Securities); (2) any limit upon the aggregate principal amount of the Securities of the series which may be authenticated and delivered under this Indenture (except for Securities authenticated and delivered upon registration of transfer of, or in exchange for, or in lieu of, other Securities of the series pursuant to Section 304, 305, 306, 906 or 1107 and, if the Securities of such series are subject to redemption or repurchase by the Company at the option of the Holders thereof, except for Securities of such series authenticated and delivered upon any such repurchase or redemption of any such Security in part, and except for any Securities which, pursuant to Section 303, are deemed never to have been authenticated and delivered hereunder); (3) whether Securities of the series are to be issuable as Registered Securities, Bearer Securities or both, whether any Securities of the series may be represented initially by a Security in temporary or definitive global form and, if so, the initial Depositary with respect to any such temporary or definitive global Security, and, if other than as provided in Section 304 or Section 305, as applicable, whether, and the circumstances under which, beneficial owners of interests in any such temporary or definitive global Security may exchange such interests for Securities of such series of like tenor of any authorized form and denomination and the Authorized Newspapers for publication of notices to holders of Bearer Securities; (4) the Person to whom any interest on any Registered Security of the series shall be payable, if other than 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, the manner in which, and the Person to whom, any interest on any Bearer Security of the 15

series shall be payable, if otherwise than upon presentation and surrender of the coupons appertaining thereto as they severally mature, and any additional or different terms with respect to the payment of interest on temporary or definitive global Securities; (5) the date or dates on which the principal of the Securities of the series is payable or the method of determination thereof; (6) the rate or rates (which may be fixed or variable) at which the Securities of the series shall bear interest, if any, or the method of calculating such rate or rates, the date or dates from which any such interest shall accrue, the Interest Payment Dates on which any such interest shall be payable and the Regular Record Date for any interest payable on any Registered Securities on any Interest Payment Date; (7) the place or places where, subject to the provisions of Section 1002, the principal of and any interest on Securities of the series shall be payable, any Registered Securities of the series may be surrendered for registration of transfer, Securities of the series may be surrendered for exchange and notices and demands to or upon the Company in respect of the Securities of the series and this Indenture may be served; (8) the period or periods within which, the price or prices at which and the terms and conditions upon which, Securities of the series may be redeemed, in whole or in part, at the option of the Company; (9) the obligation, if any, of the Company to redeem or purchase Securities of the series pursuant to any sinking fund or analogous provisions or at the option of a Holder thereof, the conditions, if any, giving rise to such obligation, and the period or periods within which, the price or prices at which and the terms and conditions upon which, Securities of the series shall be redeemed or purchased, in whole or in part, pursuant to such obligation, and any provisions for the remarketing of such Securities; (10) the denominations in which any Registered Securities of the series shall be issuable, if other than denominations of $1,000 and any integral multiple thereof, and the denomination or denominations in which any Bearer Securities of the series shall be issuable, if other than denominations of $5,000 and $100,000; (11) the currency or currencies, including composite currencies or currency units, in which Securities of the series may be denominated or in which payment of the principal of and any interest on the Securities of the series shall be payable, if other than the currency of the United States of America, and if so, whether the Securities of the series may be satisfied and discharged other than as provided in Article Four; (12) if the amounts of payments of principal of and any interest on the Securities of the series are to be determined with reference to an index, formula or other method, or 16

based on a coin or currency other than that in which the Securities are stated to be payable, the manner in which such amounts shall be determined and the calculation agent, if any, with respect thereto; (13) if other than the principal amount thereof, the portion of the principal amount of any Securities of the series which shall be payable upon declaration of acceleration of the Maturity thereof pursuant to Section 502; (14) if the Company will pay additional amounts on any of the Securities and coupons, if any, of the series to any Holder who is a Non- United States Holder (including any modification in the definition of such term), in respect of any tax, assessment or governmental charge withheld or deducted, under what circumstances, and with what procedures and documentation, the Company will pay such additional amounts, whether such additional amounts will be treated as interest or principal pursuant to this Indenture, and whether the Company will have the option to redeem such Securities rather than pay additional amounts (and the terms of any such option); (15) if other than as defined in Section 101, the meaning of "Business Day" when used with respect to any Securities of the series; (16) if the Securities of the series may be issued or delivered (whether upon original issuance or upon exchange of a temporary Security of such series or otherwise), or any installment of principal or interest is payable, only upon receipt of certain certificates or other documents or satisfaction of other conditions in addition to those specified in this Indenture, the forms and terms of such certificates, documents or conditions; (17) the right, if any, of the Company to defer payments of interest by extending the interest payment periods by a period of time to be determined by the Company, the Interest Payment Dates on which such interest shall be payable and whether and under what circumstances additional interest on amounts deferred shall be payable; (18) any addition to, or modification or deletion of, any Event of Default, covenant of the Company or other term or provision specified in this Indenture with respect to Securities of the series; (19) the terms, if other than those set forth in Article Fourteen, on which the Securities of the series will be subordinate to other Indebtedness of the Company; and (20) any other terms of the series, whether or not consistent with the other provisions of this Indenture. All Securities of any one series and the coupons appertaining to any Bearer Securities of such series shall be substantially identical, except as to denomination, the rate or rates of interest, if any, 17

the Stated Maturity, the date from which interest, if any, shall accrue, the other financial terms thereof and except as may otherwise be provided in or pursuant to an Officers' Certificate pursuant to this Section 301 or in any indenture supplemental hereto. All Securities of any one series need not be issued at the same time and, unless otherwise provided, a series may be reopened for issuances of additional Securities of such series. If any of the terms of the series are established by action taken pursuant to a Board Resolution, a copy of any appropriate record of such action shall be certified by the Secretary or an Assistant Secretary of the Company and delivered to the Trustee at or prior to the delivery of the Officers' Certificate setting forth the terms of the series. With respect to Securities of a series subject to a Periodic Offering, such Board Resolution or the Officers' Certificate or supplemental indenture setting forth or establishing the terms of such series may provide general terms for Securities of such series and provide either that the specific terms of particular Securities of such series shall be specified in a Company Order or that such terms shall be determined by the Company, or one or more of the Company's agents designated in an Officers' Certificate, in accordance with the Company Order as contemplated by the first proviso of the third paragraph of Section 303. SECTION 302. Denominations. Unless otherwise provided as contemplated by Section 301 with respect to any series of Securities, any Registered Securities of a series shall be issuable in denominations of $1,000 and any integral multiple thereof and any Bearer Securities of a series shall be issuable in denominations of $5,000 and $100,000. SECTION 303. Execution, Authentication, Delivery and Dating. The Securities shall be executed on behalf of the Company by its Chairman of the Board, its President, one of its Vice Presidents, its Treasurer, or one of its Assistant Treasurers under its corporate seal (or a facsimile thereof) reproduced thereon and attested by its Secretary or one of its Assistant Secretaries. The signature of any of these officers on the Securities may be manual or facsimile. Coupons shall bear the actual or facsimile signature of the Treasurer or an Assistant Treasurer of the Company. Securities and coupons, if any, appertaining thereto, bearing the manual or facsimile signatures of individuals who were at any time the proper officers of the Company shall bind the Company, notwithstanding that such individuals, or any of them, have ceased to hold such offices prior to the authentication and delivery of such Securities or did not hold such offices at the date of such Securities. At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Securities of any series, together with any coupons appertaining thereto, executed by the Company to the Trustee for authentication, together with a Company Order for the authentication and delivery of such Securities; and the Trustee, in accordance with such Company 18

Order, shall authenticate and deliver such Securities; provided, however, that, with respect to Securities of a series subject to a Periodic Offering, (a) such Company Order may be delivered by the Company to the Trustee prior to the delivery to the Trustee of such Securities for authentication and delivery, (b) the Trustee shall authenticate and deliver Securities of such series for original issue from time to time, in an aggregate principal amount not exceeding the aggregate principal amount established for such series, pursuant to a Company Order or pursuant to such procedures acceptable to the Trustee as may be specified from time to time by a Company Order, (c) the rate or rates of interest, if any, the Stated Maturity or Maturities, the original issue date or dates, the redemption provisions, if any, and any other terms of Securities of such series shall be determined by a Company Order or pursuant to such procedures and (d) if provided for in such procedures, such Company Order may authorize authentication and delivery pursuant to oral or electronic instructions from the Company, or the Company's duly authorized agent or agents designated in an Officers' Certificate, which oral instructions shall be promptly confirmed in writing; and provided, further, that, in connection with its original issuance, no Bearer Security or coupon shall be mailed or otherwise delivered to any Person who is not a Non-United States Holder or to any location in the United States. Except as permitted by Section 306, the Trustee shall not authenticate and deliver any Bearer Security, unless all appurtenant coupons for interest then matured have been detached and cancelled. In authenticating Securities, the form or terms of which have been established in or pursuant to one or more Officers' Certificates as permitted by Sections 201 and 301, and accepting the additional responsibilities under this Indenture in relation to such Securities, the Trustee shall be entitled to receive, and (subject to Section 601) shall be fully protected in relying upon, an Opinion of Counsel stating: (a) that the form and terms of such Securities, including any coupons, have been duly authorized by the Company and established in conformity with the provisions of this Indenture; and (b) that such Securities, together with any coupons appertaining thereto, when authenticated and delivered by the Trustee and issued by the Company in the manner and subject to any conditions specified in such Opinion of Counsel, will constitute valid and legally binding obligations of the Company, enforceable in accordance with their terms, subject to customary exceptions; provided, however, that, with respect to Securities of a series subject to a Periodic Offering, the Trustee shall be entitled to receive such Opinion of Counsel only once, at or prior to the time of the first authentication of Securities of such series, and that the Opinion of Counsel above may state: (x) that the forms of such Securities have been, and the terms of such Securities (when established in accordance with such procedures as may be specified from time to time in a Company Order, all as contemplated by and in accordance with a Board Resolution or an Officers' Certificate pursuant to Section 301, as the case may be) will have been, duly 19

authorized by the Company and established in conformity with the provisions of this Indenture; and (y) that such Securities, together with the coupons, if any, appertaining thereto, when (1) executed by the Company, (2) completed, authenticated and delivered by the Trustee in accordance with this Indenture and (3) issued by the Company in the manner and subject to any conditions specified in such Opinion of Counsel, will constitute valid and legally binding obligations of the Company, enforceable in accordance with their terms, subject to customary exceptions. With respect to Securities of a series subject to a Periodic Offering, the Trustee may conclusively rely, as to the authorization by the Company of any of such Securities, the form and terms thereof and the legality, validity, binding effect and enforceability thereof, upon the Opinion of Counsel and other documents delivered pursuant to Sections 201 and 301 and this Section, as applicable, at or prior to the time of the first authentication of Securities of such series, unless and until it has received written notification that such opinion or other documents have been superseded or revoked. In connection with the authentication and delivery of Securities of a series subject to a Periodic Offering, the Trustee shall be entitled to assume that the Company's instructions to authenticate and deliver such Securities do not violate any rules, regulations or orders of any governmental agency or commission having jurisdiction over the Company. Notwithstanding the provisions of Section 301 and of the preceding three paragraphs, if all Securities of a series are subject to a Periodic Offering, it shall not be necessary to deliver the Officers' Certificate otherwise required pursuant to Section 301 at or prior to the time of authentication of each Security of such series if such Officers' Certificate is delivered at or prior to the authentication upon original issuance of the first Security of such series to be issued. Each Registered Security shall be dated the date of its authentication; and, unless otherwise specified as contemplated by Section 301, each Bearer Security (including a Bearer Security represented by a temporary global Security) shall be dated as of the date of original issuance of the first Security of such series to be issued. The Trustee may appoint an authenticating agent acceptable to the Company to authenticate Securities. Unless otherwise provided in the appointment, an authenticating agent may authenticate Securities whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. No Security or coupon appertaining thereto shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose, unless there appears on such Security a certificate of authentication substantially in the form provided for herein, executed by the Trustee by the manual signature of one of its authorized signatories, and such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder. Notwithstanding the foregoing, if any Security shall have been duly 20

authenticated and delivered hereunder but never issued and sold by the Company, and the Company shall deliver such Security to the Trustee for cancellation as provided in Section 309, together with a written statement (which need not comply with Section 102 and need not be accompanied by an Opinion of Counsel) stating that such Security has never been issued and sold by the Company, for all purposes of this Indenture such Security shall be deemed never to have been authenticated and delivered hereunder and shall never be entitled to the benefits of this Indenture. SECTION 304. Temporary Securities. Pending the preparation of definitive Securities of any series, the Company may execute, and upon a Company Order the Trustee shall authenticate and deliver, temporary Securities that are printed, lithographed, typewritten, photocopied or otherwise produced, in any authorized denomination, substantially of the tenor of the definitive Securities in lieu of which they are issued, in registered form or, if authorized, in bearer form, with one or more coupons or without coupons, and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Securities may determine, as evidenced by their execution of such Securities. Such temporary Securities may be in global form. Except in the case of Securities represented by a temporary global Security (which shall be exchanged in accordance with the provisions of the three succeeding paragraphs), if temporary Securities for some or all of the Securities of any series are issued, the Company will cause definitive Securities representing such Securities to be prepared without unreasonable delay. After the preparation of such definitive Securities, the temporary Securities shall be exchangeable for such definitive Securities of like tenor upon surrender of such temporary Securities at any office or agency of the Company designated pursuant to Section 1002 in a Place of Payment for such series for the purpose of exchanges of Securities of such series, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Securities of any series (accompanied by any unmatured coupons appertaining thereto), the Company shall execute, and the Trustee shall authenticate and deliver in exchange therefor, a like principal amount of definitive Securities of the same series and of like tenor of authorized denominations; provided, however, that no definitive Bearer Security shall be delivered in exchange for a temporary Registered Security. Until so exchanged, the temporary Securities shall in all respects be entitled to the same benefits under this Indenture as definitive Securities. Unless otherwise specified as contemplated by Section 301, if Bearer Securities of any series are represented by a Security in temporary global form, any such temporary global Security shall be delivered to the Depositary for the benefit of Euro-clear or Cedel S.A., for credit to the respective accounts of the beneficial owners of such Securities (or to such other accounts as they may direct). Without unnecessary delay, but in any event not later than the date specified in, or determined pursuant to the terms of, any such temporary global Security (the "Exchange Date"), the Company shall deliver to the Trustee definitive Securities of the same series, in aggregate principal amount equal to the principal amount of such temporary global Security, executed by the Company. On or 21

after the Exchange Date, such temporary global Security shall be surrendered by the Depositary to the Trustee, as the Company's agent for such purpose, to be exchanged, in whole or from time to time in part, for definitive Securities of the same series and of like tenor without charge, and the Trustee shall authenticate and deliver, in exchange for each portion of such temporary global Security, an equal aggregate principal amount of definitive Securities of the same series of authorized denominations and of like tenor as the portion of such temporary global Security to be exchanged. The definitive Securities to be delivered in exchange for any such temporary global Security shall be in definitive bearer form or registered form, or shall be represented by a definitive global Security, or any combination thereof, as specified as contemplated by Section 301, and, if any combination thereof is so specified, as requested by the beneficial owner thereof. Unless otherwise specified in any such temporary global Security, the interest of a beneficial owner of Securities of a series represented by such temporary global Security shall be exchanged for definitive Securities of the same series and of like tenor following the Exchange Date, when the account holder instructs Euro-clear or Cedel S.A., as the case may be, to request such exchange on his behalf and delivers to Euro-clear or Cedel S.A., as the case may be, any certificate specified as contemplated by Section 301. Unless otherwise specified in such temporary global Security, any such exchange shall be made free of charge to the beneficial owners of such temporary global Security, except that a Person receiving definitive Securities must bear the cost of insurance, postage, transportation and the like, in the event that such Person does not take delivery of such definitive Securities in person at the offices of Euro-clear or Cedel S.A. Until exchanged in full as hereinabove provided, the temporary Securities of any series shall in all respects be entitled to the same benefits under this Indenture as definitive Securities of the same series and of like tenor authenticated and delivered hereunder, except that, unless otherwise specified as contemplated by Section 301, interest payable on a temporary global Security representing a series of Bearer Securities on an Interest Payment Date for Securities of such series occurring prior to the applicable Exchange Date shall be payable to Euro-clear and Cedel S.A. on such Interest Payment Date, upon delivery by Euro-clear and Cedel S.A. to the Trustee of any certificate specified as contemplated by Section 301, for credit, without further interest on or after such Interest Payment Date, to the respective accounts of the Persons who are the beneficial owners of such temporary global Security on such Interest Payment Date and who have each delivered to Euro-clear or Cedel S.A., as the case may be, any certificate specified as contemplated by Section 301. SECTION 305. Registration, Registration of Transfer and Exchange. (1) The Company shall cause to be kept, at one of its offices or agencies maintained pursuant to Section 1002, a register for the Securities accessible to the Trustee (the register maintained in such office or agency designated pursuant to Section 1002 being herein sometimes collectively referred to as the "Security Register"), in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Securities and of transfers of Securities. The Trustee is hereby appointed "Security Registrar" for the purpose of registering Securities and transfers of Securities as herein provided. 22

(2) Upon surrender for registration of transfer of any Security at an office or agency of the Company designated pursuant to Section 1002 for such purpose in a Place of Payment, the Company shall execute, and the Trustee or a duly appointed co-authenticating agent shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Registered Securities of the same series and of any authorized denominations, of a like aggregate principal amount and tenor. (3) Notwithstanding any other provisions (other than the provisions set forth in the seventh and eighth paragraphs) of this Section, a Security in global form representing all or a portion of the Securities of a series may not be transferred, except as a whole by the 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 Depositary for such series or a nominee of such successor Depositary. (4) At the option of the Holder, Registered Securities of any series may be exchanged for other Registered Securities of the same series of any authorized denominations and of a like aggregate principal amount, terms and tenor, upon surrender of the Securities to be exchanged at any such office or agency. Whenever any Securities are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Securities which the Holder making the exchange is entitled to receive. Bearer Securities may not be issued in exchange for Registered Securities. (5) At the option of the Holder, Bearer Securities of any series may be exchanged for Registered Securities of the same series of any authorized denominations and of a like aggregate principal amount, terms and tenor, upon surrender of the Bearer Securities to be exchanged at any such office or agency, with all unmatured coupons and all matured coupons in default thereto appertaining. If the Holder of a Bearer Security is unable to produce any such unmatured coupon or coupons or matured coupon or coupons in default, such exchange may be effected if the Bearer Securities are accompanied by payment, in funds acceptable to the Company and the Trustee, in an amount equal to the face amount of such missing coupon or coupons, or the surrender of such missing coupon or coupons may be waived by the Company and the Trustee if there is furnished to them such security or indemnity as they may require to save each of them and any Paying Agent harmless. If thereafter the Holder of such Security shall surrender to any Paying Agent any such missing coupon in respect of which such a payment shall have been made, such Holder shall be entitled to receive the amount of such payment; provided, however, that, except as otherwise provided in Section 1002, interest represented by coupons shall be payable only upon presentation and surrender of those coupons at an office or agency located outside the United States. Notwithstanding the foregoing, in case a Bearer Security of any series is surrendered at any such office or agency in exchange for a Registered Security of the same series and terms and like tenor after the close of business at such office or agency on (i) any Regular Record Date and before the opening of business at such office or agency on the relevant Interest Payment Date, or (ii) any Special Record Date and before the opening of business at such office or agency on the related proposed date 23

for payment of Defaulted Interest, such Bearer Security shall be surrendered without the coupon relating to such Interest Payment Date or proposed date for payment, as the case may be, and interest or Defaulted Interest, as the case may be, will not be payable on such Interest Payment Date or proposed date for payment, as the case may be, in respect of the Registered Security issued in exchange for such Bearer Security, but will be payable only to the Holder of such coupon when due in accordance with the provisions of this Indenture. (6) Whenever any Securities are so surrendered for exchange, the Company shall execute, and the Trustee or a duly appointed authenticating agent shall authenticate and deliver, the Securities which the Holder making the exchange is entitled to receive. (7) If at any time the Depositary for the Securities of a series notifies the Company that it is unwilling or unable to continue as Depositary for the Securities of such series, or if such Depositary shall cease to be eligible to act as such in respect of the Securities of such series, the Company shall appoint a successor Depositary with respect to the Securities of such series. If a successor Depositary for the Securities of such series is not appointed by the Company within 90 days after the Company receives such notice, 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 Security or Securities in global form representing such series, in exchange for such Security or Securities in global form in accordance with the instructions, if any, of the Depositary. (8) 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, or if an Event of Default with respect to the Securities of such series shall have occurred and shall be continuing, 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 Security or Securities in global form representing such series, in exchange for such Security or Securities in global form in accordance with the instructions, if any, of the Depositary. (9) Notwithstanding the foregoing, except as otherwise specified in the preceding two paragraphs or as contemplated by Section 301, any definitive global Security shall be exchangeable only as provided in this paragraph. If the beneficial owners of interests in a definitive global Security are entitled to exchange such interests for definitive Securities of such series and of like principal amount and tenor but of another authorized form and denomination, as specified as contemplated by Section 301, then, without unnecessary delay, but in any event not later than the earliest date on which such interests may be so exchanged, the Company shall deliver to the Trustee definitive Securities, in aggregate principal amount equal to the principal amount of such definitive global Security, executed by the Company. On or after the earliest date on which such interests may be so exchanged, such definitive global Security shall be surrendered by the Depositary with respect thereto 24

to the Trustee, as the Company's agent for such purpose, to be exchanged, in whole or from time to time in part, for definitive Securities without charge, and the Trustee shall authenticate and deliver, in exchange for each portion of such definitive global Security, an equal aggregate principal amount of definitive Securities of the same series of authorized denominations and of like tenor as the portion of such definitive global Security to be exchanged, which, unless the Securities of the series are not issuable both as Bearer Securities and as Registered Securities, as specified as contemplated by Section 301, shall be in the form of Bearer Securities or Registered Securities, or any combination thereof, as shall be specified by the beneficial owner thereof; provided, however, that notwithstanding the last paragraph of this Section 305, no such exchanges may occur during a period beginning at the opening of business 15 days before any selection of Securities of that series to be redeemed and ending on the relevant Redemption Date; and provided, further, that in connection with its original issuance, no Bearer Security or coupon delivered in exchange for a portion of a definitive global Security shall be mailed or otherwise delivered to any Person that is not a Non-United States Holder or to any location in the United States. If a Registered Security is issued in exchange for any portion of a definitive global Security after the close of business at the office or agency where such exchange occurs on (i) any Regular Record Date and before the opening of business at such office or agency on the relevant Interest Payment Date, or (ii) any Special Record Date and the opening of business at such office or agency on the related proposed date for payment of Defaulted Interest, interest or Defaulted Interest, as the case may be, will not be payable on such Interest Payment Date or proposed date for payment, as the case may be, in respect of such Registered Security, but will be payable on such Interest Payment Date or proposed date for payment, as the case may be, only to the Person to whom interest in respect of such portion of such definitive global Security is payable in accordance with the provisions of this Indenture. (10) Upon the exchange of a Security in global form for Securities in definitive form, such Security in global form shall be cancelled by the Trustee. All cancelled Securities and coupons held by the Trustee shall be disposed of by the Trustee in accordance with its customary practice and a certificate of such disposition delivered to the Company, unless the Company directs that such cancelled Securities be returned to it. Registered Securities issued in exchange for a Security in global form pursuant to this Section 305 shall be registered in such names and in such authorized denominations as the Depositary for such Security in global form, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee. The Trustee shall deliver such Registered Securities to the persons in whose names such Securities are so registered. (11) All Securities issued upon any registration of transfer or exchange of Securities shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Securities surrendered upon such registration of transfer or exchange. (12) Every Registered Security presented or surrendered for registration of transfer or for exchange shall (if so required by the Company or the Trustee) be duly endorsed, or be accompanied by a written instrument of transfer, in form satisfactory to the Company and the Security Registrar, duly executed, by the Holder thereof or his attorney duly authorized in writing. 25

(13) No service charge shall be made for any registration of transfer or exchange 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 with any registration of transfer or exchange of Securities, other than exchanges pursuant to Section 304, 906 or 1107 not involving any transfer, other than exchanges upon the Company's repurchase or redemption of any Securities in part at the option of the Holders thereof not involving any transfer, and other than exchanges of global Securities (or portions thereof) for Securities in definitive form in accordance with Section 305. The Company shall not be required (i) to issue, register the transfer of or exchange Securities of any series during a period beginning at the opening of business 15 days before any selection of Securities of that series to be redeemed and ending (except as otherwise provided in the first proviso in the ninth paragraph of this Section 305) at the close of business on (A) if Securities of the series are issuable only as Registered Securities, the day of the mailing of the relevant notice of redemption and (B) if Securities of the series are issuable as Bearer Securities, the day of the first publication of the relevant notice of redemption or, if Securities of the series are also issuable as Registered Securities and there is no publication, the mailing of the relevant notice of redemption, or (ii) to register the transfer of or exchange any Registered Security so selected for redemption, in whole or in part, except the unredeemed portion of any Registered Security being redeemed in part, or (iii) to exchange any Bearer Security so selected for redemption, except that such a Bearer Security may be exchanged for a Registered Security of that series and like tenor, terms and principal amount, provided that such Registered Security shall be simultaneously surrendered for redemption. SECTION 306. Mutilated, Destroyed, Lost and Stolen Securities and Coupons. If any mutilated Security or a Security with a mutilated coupon appertaining thereto is surrendered to the Trustee, the Company shall execute, and the Trustee shall authenticate and deliver in exchange therefor, a new Security of the same series of like tenor and principal amount and bearing a number not contemporaneously outstanding, with coupons corresponding to the coupons, if any, appertaining to the surrendered Security. If there shall be delivered to the Company and the Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any Security or coupon and (ii) such security or indemnity as may be required by them to save each of them and any agent of either of them harmless, then, in the absence of notice to the Company or the Trustee that such Security or coupon has been acquired by a bona fide purchaser, the Company shall execute, and upon its request the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen Security or in exchange for the Security to which a destroyed, lost or stolen coupon appertains (with all appurtenant coupons not destroyed, lost or stolen), a new Security of the same series and of like tenor and principal amount and bearing a number not contemporaneously outstanding, with coupons corresponding to the coupons, if any, appertaining to such destroyed, lost or stolen Security or to the Security to which such destroyed, lost or stolen coupon appertains. 26

In case any such mutilated, destroyed, lost or stolen Security or coupon has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Security, pay such Security or coupon; provided, however, that principal of and any interest on Bearer Securities shall, except as otherwise provided in Section 1002, be payable only at an office or agency located outside the United States and, unless otherwise specified as contemplated by Section 301, any interest on Bearer Securities shall be payable only upon presentation and surrender of the coupons appertaining thereto. Upon the issuance of any new Security under this Section, 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 (including the fees and expenses of the Trustee) connected therewith. Every new Security of any series issued pursuant to this Section in lieu of any destroyed, lost or stolen Security or in exchange for a Security to which a destroyed, lost or stolen coupon appertains, shall constitute an original additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Security and its coupons, if any, or the destroyed, lost or stolen coupon shall be at any time enforceable by anyone, and any such new Security and coupons, if any, shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Securities of that issue and their coupons, if any, duly issued hereunder. The provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities or coupons. SECTION 307. Payment of Interest; Interest Rights Preserved. Unless otherwise provided as contemplated by Section 301 with respect to any series of Securities, interest on any Registered Security which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall 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. In case a Bearer Security of any series is surrendered in exchange for a Registered Security of such series after the close of business (at an office or agency in a Place of Payment for such series) on any Regular Record Date and before the opening of business (at such office or agency) on the next succeeding Interest Payment Date, such Bearer Security shall be surrendered without the coupon relating to such Interest Payment Date, and interest will not be payable on such Interest Payment Date in respect of the Registered Security issued in exchange for such Bearer Security, but will be payable only to the Holder of such coupon when due in accordance with the provisions of this Indenture. Any interest on any Registered Security of any series which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date (herein called "Defaulted Interest") shall forthwith cease to be payable to the Holder on the relevant Regular Record Date by virtue of having 27

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 of such series (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 Registered 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 of Registered Securities, at his address as it appears in the Security Register, not less than 10 days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been so mailed, such Defaulted Interest shall be paid to the Persons in whose names the Securities (or their respective Predecessor Securities) are registered at the close of business 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 on the Registered Securities in any other lawful manner not inconsistent with the requirements of any securities exchange on which such Registered 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 and Section 305, 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. SECTION 308. Persons Deemed Owners. Prior to due presentment of a Registered Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name such 28

Registered Security is registered as the owner of such Registered Security for the purpose of receiving payment of principal of and (except as otherwise specified as contemplated by Section 301 and subject to Section 305 and Section 307) interest on such Registered Security and for all other purposes whatsoever, whether or not such Registered Security be overdue, and neither the Company, the Trustee nor any agent of the Company or the Trustee shall be affected by notice to the contrary. Title to any Bearer Security and any coupons appertaining thereto shall pass by delivery. The Company, the Trustee and any agent of the Company or the Trustee may treat the bearer of any Bearer Security and the bearer of any coupon as the absolute owner of such Bearer Security or coupon, as the case may be, for the purpose of receiving payment thereof or on account thereof and for all other purposes whatsoever, whether or not such Bearer Security or coupon be overdue, and neither the Company, the Trustee nor any agent of the Company or the Trustee shall be affected by notice to the contrary. None of the Company, the Trustee, any Paying Agent or the Security Registrar will have any responsibility or liability for any aspect of the records relating to, or payments made on account of, beneficial ownership interests of a Security in global form or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests. SECTION 309. Cancellation. All Securities and coupons surrendered for payment, redemption, registration of transfer or exchange or for credit against any sinking fund payment shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee. All Registered Securities and matured coupons so delivered shall be promptly cancelled by the Trustee. All Bearer Securities and unmatured coupons so delivered shall be held by the Trustee and, upon instruction by a Company Order, shall be cancelled or held for reissuance. Bearer Securities and unmatured coupons held for reissuance may be reissued only in replacement of mutilated, lost, stolen or destroyed Bearer Securities of the same series and like tenor and terms or the related coupons pursuant to Section 306. All Bearer Securities and unmatured coupons held by the Trustee pending such cancellation or reissuance shall be deemed to be delivered for cancellation for all purposes of this Indenture and the Securities. 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 (including Securities received by the Company in exchange or payment for other securities of the Company), and may deliver to the Trustee (or to any other Person for delivery to the Trustee) for cancellation any Securities previously authenticated hereunder which the Company has not issued and sold, 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 in the form of Securities for any particular series or as permitted pursuant to the terms of this Indenture. All cancelled Securities and coupons held by the Trustee may be disposed of and certification of their disposition delivered to the Company, unless by a Company Order the Company shall direct that such Securities be returned to it. Any cancelled Securities not disposed of shall be returned to the Company. 29

SECTION 310. Computation of Interest. Except as otherwise specified as contemplated by Section 301 for Securities of any series, (i) interest on any Securities which bear interest at a fixed rate shall be computed on the basis of a 360-day year of twelve 30-day months and (ii) interest on any Securities which bear interest at a variable rate shall be computed on the basis of the actual number of days in an interest period divided by 360. ARTICLE FOUR Satisfaction and Discharge SECTION 401. Satisfaction and Discharge of Indenture. Except as otherwise specified as contemplated by Section 301, this Indenture, upon a Company Request, shall cease to be of further effect as to all Outstanding Securities or all Outstanding Securities of any series, as the case may be (except as to (i) remaining rights of registration of transfer, substitution and exchange of Securities or Securities of such series, as the case may be, (ii) rights hereunder of Holders to receive payment of principal of and interest on all Outstanding Securities or all Outstanding Securities of such series, as the case may be, at the Stated Maturity thereof or, if any such Securities have been or, pursuant to clause (1)(B)(ii) of this Section 401, are to be called for redemption, at the applicable Redemption Date thereof and any other rights of the Holders of all Outstanding Securities or all Outstanding Securities of such series, as the case may be, as beneficiaries hereof with respect to the amounts deposited with the Trustee under this Section 401, (iii) the rights and the obligations of the Company or the Trustee under Sections 304, 305, 306, 1002 and 1003 and the immunities of the Trustee hereunder and the obligations of the Company to the Trustee under Section 607 and (iv) the obligation, if any, of the Company to pay additional amounts in respect of any such Securities as contemplated by Sections 301 and 1011, all of which shall survive), and the Company shall be deemed to have paid and discharged its entire indebtedness on all the Outstanding Securities or all Outstanding Securities of such series, as the case may be, and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of the Company's obligations under this Indenture, when (1) either (A) all Outstanding Securities or all Outstanding Securities of such series, as the case may be, theretofore authenticated and delivered, and all coupons, if any, appertaining thereto (other than (i) coupons appertaining to Bearer Securities surrendered for exchange for Registered Securities and maturing after such exchange, whose surrender is not required or has been waived as provided in Section 305, (ii) Securities or Securities of such series, as the case may be, and coupons, if any, which have been destroyed, lost or stolen and which have been replaced or paid as provided 30

in Section 306, (iii) coupons, if any, appertaining to Securities or Securities of such series, as the case may be, called for redemption and maturing after the relevant Redemption Date, whose surrender has been waived as provided in Section 1106, and (iv) Securities or Securities of such series, as the case may be, and coupons, if any, 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 1003) have been delivered to the Trustee for cancellation; or (B) the Company has irrevocably deposited or caused to be deposited with the Trustee, under the terms of an irrevocable trust agreement in form and substance satisfactory to the Trustee, as trust funds in trust solely for the benefit of the Holders of all Outstanding Securities, or the Holders of all Outstanding Securities of such series, as the case may be, money or direct non-callable obligations of, or non-callable obligations timely payments of which are guaranteed by, the United States of America, for the payment of which guarantee or obligation the full faith and credit of the United States is pledged ("U.S. Government Obligations"), maturing as to principal and interest in such amounts and at such times as are sufficient, without consideration of any reinvestment of such principal or interest, to pay and discharge at Stated Maturity or, in the case of any such Securities which have been or, pursuant to clause (ii) below, are to be called for redemption, on the relevant Redemption Date, as the case may be, all principal of and interest on all Outstanding Securities or all Outstanding Securities of such series, as the case may be. Such irrevocable trust agreement shall instruct the Trustee (i) to apply such money or the proceeds of said U.S. Government Obligations to the payment of said principal of and interest on the Securities or Securities of such series, as the case may be; and (ii) if the Securities or Securities of such series, as the case may be, are to be repaid at a Redemption Date and the Company has not given notice of redemption pursuant to Section 1104 (including where such Securities are not yet redeemable at the date of deposit) to give notice of redemption on such Redemption Date pursuant to Section 1104; (2) the Company has paid or caused to be paid all other sums payable hereunder by the Company with respect to the Securities or Securities of such series, as the case may be; 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 with respect to the Securities or the Securities of such series, as the case may be, and the payment or discharge of the entire indebtedness on all Securities or Securities of such series, as the case may be, have been complied with. Notwithstanding any such satisfaction and discharge, the Company shall not be discharged from any payment obligations in respect of the Securities or the Securities of such series, as the case 31

may be, which are deemed not to be Outstanding under Clause (iii) of the definition of "Outstanding" if such obligations continue to be valid obligations of the Company under applicable law. SECTION 402. Application of Trust Money. All money and U.S. Government Obligations (or any other obligations specified as contemplated by Section 301 with respect to any series of Securities, the principal of or any interest on which is payable other than in the currency of the United States of America) deposited with the Trustee pursuant to the trust agreement referred to in Section 401 shall be held in trust and applied by it, in accordance with the provisions of the Securities of the series with respect to which such deposit is made, this Indenture and such trust agreement, to the payment, either directly or through any Paying Agent (other than the Company) as the Trustee may determine, of the principal and interest amounts due at the Stated Maturity or the Redemption Date, as the case may be, with respect to the Securities of such series to the Persons entitled thereto. All money and U.S. Government Obligations (or any other obligations specified as contemplated by Section 301 with respect to any series of Securities, the principal of or any interest on which is payable other than in the currency of the United States of America) so deposited which remain unclaimed for two years after payment to such Persons has become due and payable shall be turned over to the Company in accordance with the provisions of Section 1003. ARTICLE FIVE Remedies SECTION 501. Events of Default. "Event of Default," wherever used herein, means, with respect to each series of the Securities individually, any one of the following events (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body): (1) default in the payment of any installment of interest upon any Security of such series when it becomes due and payable, and continuance of such default for a period of 30 days; provided, however, that a valid extension of an interest payment period by the Company in accordance with the terms of the Securities of such series shall not constitute a default in the payment of interest for this purpose; or (2) default in the payment of the principal of any Security of such series at its Maturity; or 32

(3) default in the performance, or breach, of any covenant or warranty of the Company in this Indenture (other than a covenant or warranty a default in whose performance or whose breach is elsewhere in this Section specifically dealt with or which has been expressly included in this Indenture solely for the benefit of a series of Securities other than such series), and continuance of such default or breach for a period of 90 days after there has been given, by registered or certified mail, to the Company by the Trustee or to the Company and the Trustee by the Holders of at least 25% in principal amount of the Outstanding Securities of such series a written notice specifying such default or breach and requiring it to be remedied and stating that such notice is a "Notice of Default" hereunder; or (4) the entry of a decree or order by a court having jurisdiction in the premises adjudging the Company a bankrupt or insolvent, or approving as properly filed a petition seeking reorganization, arrangement, adjustment or composition of or in respect of the Company under Federal bankruptcy law or any other applicable Federal or State law, or appointing a receiver, liquidator, assignee, trustee, sequestrator or other similar official of the Company or of any substantial part of its property, or ordering the winding up or liquidation of its affairs, and the continuance of any such decree or order unstayed and in effect for a period of 60 consecutive days; or (5) the institution by the Company of proceedings to be adjudicated a bankrupt or insolvent, or the consent by it to the institution of bankruptcy or insolvency proceedings against it, or the filing by it of a petition or answer or consent seeking reorganization or relief under Federal bankruptcy law or any other applicable Federal or state law, or the consent by it to the filing of such petition or to the appointment of a receiver, liquidator, assignee, trustee, sequestrator or similar official of the Company or of any substantial part of its property, or the making by it of an assignment for the benefit of creditors, or the admission by it in writing of its inability to pay its debts generally as they become due, or the taking of corporate action by the Company in furtherance of any such action, or (6) any other event designated as an "Event of Default" with respect to Securities of that series. SECTION 502. Acceleration of Maturity; Rescission and Annulment. If an Event of Default with respect to Securities of any series at the time Outstanding occurs and is continuing, then and in every such case the Trustee or the Holders of not less than 25% in principal amount of the Outstanding Securities of that series may declare the principal amount (or, if any of the Securities of that series are Discount Securities, such portion of the principal amount of such Securities as may be specified in the terms thereof) of and accrued interest, if any, on all of the Securities of that series to be due and payable immediately, by a notice in writing to the Company (and to the Trustee if given by Holders), and upon any such declaration such principal (or portion thereof) and accrued interest, if any, shall become immediately due and payable. 33

At any time after such a declaration of acceleration with respect to Securities of any series has been made and before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter in this Article provided, the Holders of a majority in principal amount of the Outstanding Securities of that series, by written notice to the Company and the Trustee, may rescind and annul such declaration and its consequences if: (1) the Company has paid or deposited with the Trustee a sum sufficient to pay (A) all overdue installments of interest on all Securities of such series; (B) the principal of any Securities of such series which have become due otherwise than by such declaration of acceleration and interest thereon at the rate or rates prescribed therefor in such Securities; (C) to the extent that payment of such interest is lawful, interest upon overdue installments of interest at the rate or rates prescribed therefor in such Securities or, if no such rate or rates is prescribed therefor in such Securities, at the rate of interest borne by such Securities; and (D) all sums paid or advanced by the Trustee hereunder and the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel and any other amount due the Trustee under Section 607; and (2) all Events of Default with respect to Securities of such series, other than the non-payment of the principal of and interest on Securities of such series which have become due solely by such declaration of acceleration, have been cured or waived as provided in Section 513. No such rescission shall affect any subsequent default or impair any right consequent thereon. SECTION 503. Collection of Indebtedness and Suits for Enforcement by Trustee. The Company covenants that if: (1) default is made in the payment of any installment of interest on any Security when such interest becomes due and payable and such default continues for a period of 30 days, or (2) default is made in the payment of the principal of any Security at the Maturity thereof, 34

the Company will, upon demand of the Trustee, pay to it, for the benefit of the Holders of such Securities, the whole amount then due and payable on such Securities for principal and interest, with interest upon the overdue principal and, to the extent that payment of such interest shall be legally enforceable, upon overdue installments of interest from the date such interest was due, at the rate or rates prescribed therefor in such Securities or, if no such rate or rates is prescribed therefor in such Securities, at the rate of interest borne by such Securities; and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel and any other amount due the Trustee under Section 607. If the Company fails to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Company or any other obligor upon such Securities and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of the Company or any other obligor upon such Securities, wherever situated. If an Event of Default with respect to Securities of any series occurs and is continuing, the Trustee may, in its discretion, proceed to protect and enforce its rights and the rights of the Holders of Securities of such series by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy. SECTION 504. Trustee May File Proofs of Claim. In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Company or any other obligor upon the Securities or the property of the Company or of such other obligor or their creditors, the Trustee (irrespective of whether the principal of the Securities 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 on the Company for the payment of overdue principal or interest) shall be entitled and empowered, by intervention in such proceeding or otherwise, (i) to file and prove a claim for the whole amount of principal and interest owing and unpaid in respect of the Securities and to file such other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel and any other amount due the Trustee under Section 607) and of the Holders of Securities and coupons allowed in such judicial proceeding, and (ii) to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same; 35

and any receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Holder of Securities and coupons 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 of Securities and coupons, to pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 607. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder of a Security or coupon any plan of reorganization, arrangement, adjustment or composition affecting the Securities or coupons or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder of a Security or coupon in any such proceeding. SECTION 505. Trustee May Enforce Claims Without Possession of Securities or Coupons. All rights of action and claims under this Indenture or the Securities or coupons may be prosecuted and enforced by the Trustee without the possession of any of the Securities or coupons or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Securities and coupons in respect of which such judgment has been recovered. SECTION 506. Application of Money Collected. Any money collected by the Trustee pursuant to this Article shall be applied in the following order, at the date or dates fixed by the Trustee, and, in case of the distribution of such money on account of principal or interest, upon presentation of the Securities or coupons, or both, as the case may be, and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid: First: To the payment of all amounts due the Trustee under Section 607; Second: To holders of Senior Indebtedness as provided in Article Fourteen; Third: To the payment of the amounts then due and unpaid for principal of and interest on the Securities and interest evidenced by coupons in respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable on such Securities and coupons for principal and interest, respectively; and Fourth: To the payment of the remainder, if any, to the Company. 36

SECTION 507. Limitation on Suits. No Holder of any Security of any series or any related coupons shall have any right to institute any proceeding, judicial or otherwise, with respect to this Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless: (1) such Holder has previously given written notice to the Trustee of a continuing Event of Default with respect to the Securities of that series; (2) the Holders of not less than 25% in principal amount of the Outstanding Securities of that series shall have made written request to the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee hereunder; (3) such Holder or Holders have offered to the Trustee reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request; (4) the Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding; and (5) no direction inconsistent with such written request has been given to the Trustee during such 60-day period by the Holders of a majority in principal amount of the Outstanding Securities of that series; it being understood and intended that no one or more Holders shall 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 Holders, or to obtain or to seek to obtain priority or preference over any other Holders or to enforce any right under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all the Holders. SECTION 508. Unconditional Right of Holders to Receive Principal and Interest. Notwithstanding any other provision in this Indenture, the Holder of any Security or coupon shall have the right, which is absolute and unconditional, subject to Article Fourteen, to receive payment of the principal of and (subject to Section 307) interest on such Security or payment of such coupon on the Stated Maturities or Maturities expressed in such Security or coupon (or, in the case of redemption, on the Redemption Date or, in the case of redemption or repurchase by the Company at the option of the Holder, on the date fixed for such redemption or repurchase, as the case may be) and to institute suit for the enforcement of any such payment and such rights shall not be impaired without the consent of such Holder. 37

SECTION 509. Restoration of Rights and Remedies. If the Trustee or any Holder of a Security or coupon has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceeding, the Company, the Trustee and the Holders of Securities and coupons shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted. SECTION 510. Rights and Remedies Cumulative. Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities or coupons in the last paragraph of Section 306, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders of Securities or coupons is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy. SECTION 511. Delay or Omission Not Waiver. No delay or omission of the Trustee or of any Holder of any Security or coupon to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to the Holders of Securities or coupons may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders of Securities or coupons, as the case may be. SECTION 512. Control by Holders of Securities. The Holders of a majority in principal amount of the Outstanding Securities of any series 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 that (1) such direction shall not be in conflict with any rule of law or with this Indenture, (2) the Trustee shall not have determined that the action so directed would be unjustly prejudicial to the Holders not taking part in such direction, and 38

(3) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction. SECTION 513. Waiver of Past Defaults. The Holders of not less than a majority in principal amount of the Outstanding Securities of any series, by notice to the Trustee (and without notice to any other Holder), may on behalf of the Holders of all the Securities of such series and any related coupons waive any past default hereunder and its consequences, except a default (1) in the payment of the principal of or interest on any Security of such series, or (2) in respect of a covenant or provision hereof which under Article Nine cannot be modified or amended without the consent of the Holder of each Outstanding Security of such series affected. Upon any such waiver, such default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other default or impair any right consequent thereon. SECTION 514. Undertaking for 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, suffered 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 shall not apply to any suit instituted by the Trustee, to any suit instituted by any Holder, or group of Holders, holding in the aggregate more than 10% in principal amount of the Outstanding Securities of any series, or to any suit instituted by any Holder of any Security or coupon for the enforcement of the payment of the principal of or interest on any Security or the payment of any coupon on or after the Stated Maturity or Maturities expressed in such Security or coupon (or, in the case of redemption, on or after the Redemption Date or, in the case of redemption or repurchase by the Company at the option of the Holder, on the date fixed for such redemption or repurchase, as the case may be). 39

SECTION 515. Waiver of Usury, Stay or Extension Laws. The Company covenants (to the extent that it may lawfully do so) that it will not at any time voluntarily (and that it will resist any effort to make it do so involuntarily) insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any usury, stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Indenture or the Securities; and the Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted. ARTICLE SIX The Trustee SECTION 601. Certain Duties and Responsibilities. (a) Except during the continuance of an Event of Default, (1) the Trustee undertakes to perform such duties and only such duties as are specifically set forth in this Indenture, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and (2) in the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture; but in the case of any such certificates or opinions which by any provision hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform to the requirements of this Indenture. (b) In case an Event of Default has occurred and is continuing with respect to the Securities of any series, the Trustee shall exercise such of the rights and powers vested in it by this Indenture with respect to the Securities of such series, and use the same degree of care and skill in their exercise, as a prudent person would exercise or use under the circumstances in the conduct of his own affairs. (c) No provision of this Indenture shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent failure to act, or its own willful misconduct, except that: 40

(1) this Subsection shall not be construed to limit the effect of Subsection (a) of this Section; (2) the Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer, unless it shall be proved that the Trustee was negligent in ascertaining the pertinent facts; and (3) the Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with the direction of the Holders of a majority in principal amount of the Outstanding Securities of any series relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Indenture with respect to the Securities of such series. (d) No provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it.

(2) the Trustee shall cease to be eligible under Section 608 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 shall be adjudged a bankrupt or insolvent or a receiver of the Trustee or of its property shall be appointed or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, then, in any such case, (i) the Company, by a Board Resolution, may remove the Trustee with respect to all Securities, or (ii) subject to Section 514, any Holder who has been a bona fide Holder of a Security for at least six months (or such shorter period as the Securities have been outstanding) may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee with respect to all Securities and the appointment of a successor Trustee or Trustees. (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 or Trustees with respect to the Securities of that or those series (it being understood that any such successor Trustee may be appointed with respect to the Securities of one or more or all of such series and that at any time there shall be only one Trustee with respect to the Securities of any particular series). 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 with respect to the Securities of any series 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 (or such shorter period as the Securities have been outstanding) 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. (f) The Company shall give notice of each resignation and each removal of the Trustee with respect to the Securities of any series and each appointment of a successor Trustee with respect to the Securities of any series in the manner provided in Section 106. Each notice shall include the name of the successor Trustee and the address of its Corporate Trust Office. SECTION 610. Acceptance of Appointment by Successor. (a) In case of the appointment hereunder of a successor Trustee with respect to all Securities, every such successor Trustee appointed shall execute, acknowledge and deliver to the 45

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 607. (b) 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 retiring Trustee and each successor Trustee with respect to the Securities of one or more series shall execute and deliver an indenture supplemental hereto, wherein each successor Trustee shall accept such appointment and which (1) shall contain such provisions as shall be necessary or desirable to transfer and confirm to, and to vest in, each successor Trustee all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series to which the appointment of such successor Trustee relates, (2) if the retiring Trustee is not retiring with respect to all Securities, shall contain such provisions as shall be deemed necessary or desirable to confirm that all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series as to which the retiring Trustee is not retiring shall continue to be vested in the retiring Trustee, and (3) 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 as co-trustees of the same trust and that each such 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; and, upon the execution and delivery of such supplemental indenture, the resignation or removal of the retiring Trustee shall become effective to the extent provided therein and each 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 with respect to the Securities of that or those series to which the appointment of such successor Trustee relates; but, on request of the Company or any successor Trustee, such retiring Trustee shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder with respect to the Securities of that or those series to which the appointment of such successor Trustee relates, subject, nevertheless, to its lien, if any, provided for in Section 607. (c) 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 referred to in paragraph (a) or (b) of this Section. (d) 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. 46

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 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 Securities 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 612. Preferential Collection of Claims Against Company. The Trustee shall comply with Trust Indenture Act Section 311(a), excluding any creditor relationship listed in Trust Indenture Act Section 311(b).

The Company covenants and agrees for the benefit of each series of Securities that it will duly and punctually pay the principal of and any interest on the Securities of that series in accordance with the terms of the Securities, any coupons appertaining thereto and this Indenture. An installment of principal or interest on the Securities shall be considered paid on the date it is due if the Trustee or a Paying Agent (other than the Company or an Affiliate of the Company) holds on that date funds (in the currency or currencies of payment with respect to such Securities) designated for and sufficient to pay such installment. Unless otherwise specified as contemplated by Section 301 with respect to any series of Securities, any interest due on Bearer Securities on or before Maturity shall be payable only upon presentation and surrender of the several coupons for such interest installments as are evidenced thereby as they severally mature. At the Company's option, payment of principal or interest may be made by check or by transfer to an account maintained by the payee (provided, in the case of Registered Securities, the Trustee has received written payment instructions at least fifteen days prior to any payment date) subject, in the case of Bearer Securities, to the provisions of Section 1002. 53

SECTION 1002. Maintenance of Office or Agency. If Securities of a series are issuable only as Registered Securities, the Company will maintain in each Place of Payment for such series an office or agency where Securities of that series may be presented or surrendered for payment, where Securities of that series may be surrendered for registration of transfer or exchange and where notices and demands to or upon the Company in respect of the Securities of that series and this Indenture may be served. If Securities of a series are issuable as Bearer Securities, the Company will maintain (A) in the Borough of Manhattan, The City of New York, an office or agency where any Registered Securities of that series may be presented or surrendered for payment, where any Registered Securities of that series may be surrendered for registration of transfer, where Securities of that series may be surrendered for exchange, where notices and demands to or upon the Company in respect of the Securities of that series and this Indenture may be served and where Bearer Securities of that series and related coupons may be presented or surrendered for payment in the circumstances described in the following paragraph (and not otherwise); (B) subject to any laws or regulations applicable thereto, in a Place of Payment for that series which is located outside the United States, an office or agency where Securities of that series and related coupons may be presented and surrendered for payment (including payment of any additional amounts payable on Securities of that series pursuant to Section 1011); provided, however, that, if the Securities of that series are listed on The London Stock Exchange, the Luxembourg Stock Exchange or any other stock exchange located outside the United States and such stock exchange shall so require, the Company will maintain a Paying Agent for the Securities of that series in London, Luxembourg or any other required city located outside the United States, as the case may be, so long as the Securities of that series are listed on such exchange; and (C) subject to any laws or regulations applicable thereto, in a Place of Payment for that series which is located outside the United States, an office or agency where any Registered Securities of that series may be surrendered for registration of transfer, where Securities of that series may be surrendered for exchange and where notices and demands to or upon the Company in respect of the Securities of that series and this Indenture may be served. The Company will give prompt written notice to the Trustee and the Holders of the location, and any change in the location, of any such office or agency. If at any time the Company shall fail to maintain any such required office or agency in respect of any series of Securities, or shall fail to furnish the Trustee with the address thereof, such presentations and surrenders of Securities of that series may be made, and notices and demands may be made or served, at the Corporate Trust Office of the Trustee, except that Bearer Securities of that series and the related coupons may be presented and surrendered for payment (including payment of any additional amounts payable on Bearer Securities of that series pursuant to Section 1011) at the place specified for that purpose as contemplated by Section 301 or, if no such place is specified, at the main office of the Trustee in London, and the Company hereby appoints the same as its agent to receive such respective presentations, surrenders, notices and demands. No payment of principal or interest on Bearer Securities shall be made at any office or agency of the Company in the United States, by check mailed to any address in the United States, by transfer to an account located in the United States or upon presentation or surrender in the United States of 54

a Bearer Security or coupon for payment, even if the payment would be credited to an account located outside the United States; provided, however, that, if the Securities of a series are denominated and payable in Dollars, payment of principal of and any interest on any such Bearer Security (including any additional amounts payable on Securities of such series pursuant to Section 1011) shall be made at the office of the Company's Paying Agent in the Borough of Manhattan, The City of New York, if (but only if) payment in Dollars of the full amount of such principal, interest or additional amounts, as the case may be, at all offices or agencies outside the United States maintained for the purpose by the Company in accordance with this Indenture is illegal or effectively precluded by exchange controls or other similar restrictions. The Company may also from time to time designate one or more other offices or agencies where the Securities of one or more series may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in accordance with the requirements set forth above for Securities of any series for such purposes. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency. Unless otherwise specified pursuant to Section 301 with respect to the Securities of any series, the Trustee shall be a Paying Agent and Transfer Agent for the Securities of such series (until replaced or removed by the Company in accordance with this Indenture), and the office or agency of the Company maintained in the Borough of Manhattan, The City of New York in respect of the Securities of such series for the purposes contemplated by this Section 1002 shall be the Corporate Trust Office of the Trustee located in the Borough of Manhattan, The City of New York. SECTION 1003. Money for Security Payments to Be Held in Trust. If the Company shall at any time act as its own Paying Agent with respect to any series of the Securities, it will, on or before each due date of the principal of or interest on any of the Securities of that series, segregate and hold in trust for the benefit of the Persons entitled thereto a sum sufficient to pay the principal or interest so becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein provided and will promptly notify the Trustee of its action or failure so to act. Whenever the Company shall have one or more Paying Agents for any series of the Securities, it will, on or prior to each due date of the principal of or interest on any Securities of that series, deposit with a Paying Agent a sum sufficient to pay the principal or interest so becoming due, such sum to be held in trust for the benefit of the Persons entitled to such principal or interest, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of its action or failure so to act. 55

The Company will cause each Paying Agent for any series of Securities (other than the Trustee) to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions of this Section, that such Paying Agent will: (1) hold all sums held by it for the payment of the principal of or interest on Securities of such series in trust for the benefit of the Persons entitled thereto until such sums shall be paid to such Persons or otherwise disposed of as herein provided; (2) give the Trustee notice of any default by the Company (or any other obligor upon the Securities of such series) in the making of any payment of principal or interest on the Securities of such series; and (3) at any time during the continuance of any such default, upon the written request of the Trustee, forthwith pay to the Trustee all sums so held in trust by such Paying Agent. 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 interest on any Security of any series and remaining unclaimed for two years after such principal 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 or any coupon appertaining thereto 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 and direction of the Company cause to be published once, in an Authorized Newspaper in each Place of Payment, 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 balance of such money then remaining will be repaid to the Company. SECTION 1004. Corporate Existence. Subject to Article Eight, the Company will do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence, rights (charter and statutory) and franchises; provided, however, that the Company shall not be required to preserve any such right or franchise if the Board of Directors shall determine that the preservation thereof is no longer desirable 56

in the conduct of the business of the Company and that the loss thereof is not disadvantageous in any material respect to the Holders. SECTION 1005. (Intentionally Omitted). SECTION 1006. (Intentionally Omitted). SECTION 1007. (Intentionally Omitted). SECTION 1008. (Intentionally Omitted). SECTION 1009. Statement by Officer as to Compliance; Notice of Certain Events. The Company will deliver to the Trustee, within 120 days after the end of each fiscal year of the Company ending after the date hereof, a brief certificate, signed by the principal executive officer, the principal financial officer or the principal accounting officer of the Company, as to the signer's knowledge of the Company's compliance with all conditions and covenants under this Indenture. For purposes of this Section 1009, such compliance shall be determined without regard to any period of grace or requirement of notice provided under any of the provisions of this Indenture. The Company's fiscal year ends on December 31 of each year. The Company will notify the Trustee in the event that such fiscal year changes. The Company will deliver to the Trustee, within 20 days after the occurrence thereof, notice of each acceleration which, with giving of notice by the Trustee or Holders and the lapse of time, would be an Event of Default within the meaning of Section 501(4). SECTION 1010. Waiver of Certain Covenants. The Company may omit in any particular instance to comply with any covenant or condition set forth in Section 1004 or 1011 with respect to the Securities of any series, if before or after the time for such compliance the Holders of at least a majority in principal amount of the Outstanding Securities of such series shall, by Act of such Holders, either waive such compliance in such instance or generally waive compliance with such covenant or condition, 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 1011. Additional Amounts. If specified as contemplated by Section 301, the Securities of a series may provide for the payment of additional amounts, and in such case, the Company will pay to the Holder of any Security of such series or any coupon appertaining thereto additional amounts as provided therein. Whenever in this Indenture there is mentioned, in any context, the payment of the principal of or any interest on, or in respect of, any Security of any series or payment of any related coupon, such mention shall be deemed to include mention of the payment of additional amounts provided for in this Section to the 57

extent that, in such context, additional amounts are, were or would be payable in respect thereof pursuant to the provisions of this Section, and express mention of the payment of additional amounts (if applicable) in any provisions hereof shall not be construed as excluding additional amounts in those provisions hereof where such express mention is not made. If the Securities of a series provide for the payment of additional amounts, at least 10 days prior to the first Interest Payment Date with respect to that series of Securities (or if the Securities of that series will not bear interest prior to Maturity, the first day on which a payment of principal is made), and at least 10 days prior to each date of payment of principal and any interest if there has been any change with respect to the matters set forth in the below-mentioned Officers' Certificate, the Company will furnish the Trustee and the Company's Paying Agent or Paying Agents, if other than the Trustee, with an Officers' Certificate instructing the Trustee and such Paying Agent or Paying Agents whether such payment of principal of and any interest on the Securities of that series shall be made to Holders of Securities of that series or any related coupons who are Non-United States Holders without withholding for or on account of any tax, assessment or other governmental charge described in the Securities of that series. If any such withholding shall be required, then such Officers' Certificate shall specify by country the amount, if any, required to be withheld on such payments to such Holders of Securities or coupons, and the Company will pay to the Trustee or such Paying Agent the additional amounts required by the Securities of such series and this Section. The Company covenants to indemnify the Trustee and any Paying Agent for, and to hold them harmless against, any loss, liability or expense reasonably incurred, without negligence or bad faith on their part, arising out of or in connection with actions taken or omitted by any of them in reliance on any Officers' Certificate furnished pursuant to this Section. ARTICLE ELEVEN Redemption of Securities SECTION 1101. Applicability of Article. Securities of any series which are redeemable before their Stated Maturity shall be redeemable in accordance with their terms and (except as otherwise specified as contemplated by Section 301 for Securities of any series) in accordance with this Article. SECTION 1102. Election to Redeem; Notice to Trustee. In the event that the Company elects to redeem Securities of any series, the Company shall, at least 60 days prior to the Redemption Date fixed by the Company (unless a shorter notice shall be satisfactory to the Trustee), notify the Trustee of such Redemption Date, of the principal amount of the Securities to be redeemed and of any other information necessary to identify the Securities of such series to be redeemed. 58

SECTION 1103. Selection by Trustee of Securities to be Redeemed. Unless otherwise specified as contemplated by Section 301 with respect to any series of Securities, if less than all the Securities of any series with the same issue date, interest rate, Stated Maturity and other terms are to be redeemed, the particular Securities to be redeemed shall be selected not more than 60 days prior to the Redemption Date by the Trustee, from the Outstanding Securities of such series not previously called for redemption, by such method as the Trustee shall deem fair and appropriate, which method may provide for the selection for redemption of portions (equal to the minimum authorized denomination for Securities of that series or any integral multiple thereof) of the principal amount of Registered Securities of such series of a denomination larger than the minimum authorized denomination for Securities of that series. The Trustee shall promptly notify the Company in writing of the Securities selected for redemption and, in the case of any Securities selected for partial redemption, the principal amount thereof to be redeemed. For all purposes of this Indenture, unless the context otherwise requires, all provisions relating to the redemption of Securities shall relate, in the case of any Securities redeemed or to be redeemed only in part, to the portion of the principal amount of such Securities which has been or is to be redeemed. SECTION 1104. Notice of Redemption. Unless otherwise specified as contemplated by Section 301 with respect to any series of Securities, notice of redemption shall be given in the manner provided in Section 106 to the Holders of Securities to be redeemed not less than 30 nor more than 60 days prior to the Redemption Date. All notices of redemption shall identify the Securities to be redeemed (including, if applicable, the CUSIP number thereof) and shall state: (1) the Redemption Date; (2) the Redemption Price; (3) if fewer than all the Outstanding Securities of any series are to be redeemed, the identification (and, in the case of partial redemption, the principal amounts) of the particular Securities to be redeemed; (4) that on the Redemption Date the Redemption Price will become due and payable upon each such Security (or portion thereof) to be redeemed, together with (if applicable) accrued and unpaid interest thereon and, if applicable, that interest thereon will cease to accrue on and after said date; 59

(5) the place or places where such Securities, together, in the case of Bearer Securities, with all coupons, if any, appertaining thereto maturing after the Redemption Date, are to be surrendered for payment of the Redemption Price, and (6) that the redemption is for a sinking fund, if such is the case. A notice of redemption published as contemplated by Section 106 need not identify particular Registered Securities to be redeemed. Notice of redemption of Securities to be redeemed at the election of the Company shall be given by the Company or, at the Company's request, by the Trustee in the name and at the expense of the Company. SECTION 1105. Deposit of Redemption Price. On or prior to any Redemption Date, the Company shall deposit with the Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 1003) an amount of money sufficient to pay the Redemption Price of, and, if accrued and unpaid interest on the Securities (or portions thereof) to be redeemed is, pursuant to the terms of this Indenture or such Securities, payable to the Persons entitled to receive the Redemption Price thereof, accrued interest on, all the Securities which are to be redeemed on that date. SECTION 1106. Securities Payable on Redemption Date. Notice of redemption having been given as aforesaid, the Securities so to be redeemed shall, on the Redemption Date, become due and payable at the Redemption Price therein specified, and from and after such date (unless the Company shall default in the payment of the Redemption Price and accrued interest) such Securities shall cease to bear interest and the coupons for such interest appertaining to any Bearer Securities so to be redeemed, except to the extent provided below, shall be void. Upon surrender of any such Security for redemption in accordance with said notice, together with all coupons, if any, appertaining thereto maturing after the Redemption Date, such Security shall be paid by the Company at the Redemption Price, together with accrued interest to the Redemption Date; provided, however, that installments of interest on Bearer Securities whose Stated Maturity is on or prior to the Redemption Date shall be payable only at an office or agency located outside the United States (except as otherwise provided in Section 1002) and, unless otherwise specified as contemplated by Section 301, only upon presentation and surrender of coupons for such interest; and provided, further, that, unless otherwise specified as contemplated by Section 301, installments of interest on Registered Securities whose Stated Maturity is on or prior to the Redemption Date shall be payable to the Holders of such Securities, or one or more Predecessor Securities, registered as such at the close of business on the relevant Regular Record Dates according to their terms and the provisions of Sections 305 and 307. 60

If any Bearer Security surrendered for redemption shall not be accompanied by all appurtenant coupons maturing after the Redemption Date, such Security may be paid after deducting from the Redemption Price an amount equal to the face amount of all such missing coupons, or the surrender of such missing coupon or coupons may be waived by the Company and the Trustee if there be furnished to them such security or indemnity as they may require to save each of them and any Paying Agent harmless. If thereafter the Holder of such Security shall surrender to the Trustee or any Paying Agent any such missing coupon in respect of which a deduction shall have been made from the Redemption Price, such Holder shall be entitled to receive the amount so deducted; provided, however, that interest represented by coupons shall be payable only at an office or agency located outside the United States (except as otherwise provided in Section 1002) and, unless otherwise specified as contemplated by Section 301, only upon presentation and surrender of those coupons. If any Security called for redemption shall not be so paid upon surrender thereof for redemption, the principal shall, until paid, bear interest from the Redemption Date at the rate prescribed therefor in the Security or, if no such rate is so prescribed, at the rate of interest borne by the Security. SECTION 1107. Securities Redeemed in Part. Any Registered Security which is to be redeemed only in part shall be surrendered at a Place of Payment therefor (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or his attorney duly authorized in writing), and the Company shall execute, and the Trustee shall authenticate and deliver to the Holder of such Security without service charge, a new Registered Security or Securities of the same series and of like tenor, of any authorized denomination as requested by such Holder, in aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the Security so surrendered. ARTICLE TWELVE Sinking Funds SECTION 1201. 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 301 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." If provided for by the terms of Securities of any series, the cash amount of any sinking fund payment may be subject to reduction as provided in Section 1202. Each 61

sinking fund payment shall be applied to the redemption of Securities of any series as provided for by the terms of Securities of such series. SECTION 1202. Satisfaction of Sinking Fund Payments with Securities. The Company (1) may deliver Outstanding Securities of a series with the same issue date, interest rate, and Stated Maturity and other terms (other than any previously called for redemption), together, in the case of any Bearer Securities of such series with the same issue date, interest rate, Stated Maturity and other terms, with all unmatured coupons appertaining thereto, and (2) may apply as a credit Securities of a series with the same issue date, interest rate, Stated Maturity and other terms 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, in each case in satisfaction of all or any part of any mandatory sinking fund payment with respect to the Securities of such series with the same issue date, interest rate, Stated Maturity and other terms; 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 sinking fund payment shall be reduced accordingly. SECTION 1203. Redemption of Securities for Sinking Fund. Not less than 60 days (or such shorter period as shall be acceptable to the Trustee) prior to each sinking fund payment date for any series of Securities, the Company will deliver to the Trustee an Officers' Certificate specifying the amount of the next ensuing sinking fund payment for that series pursuant to the terms of that series, 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 and crediting Securities of that series pursuant to Section 1202, and will also deliver to the Trustee any Securities to be so delivered. Not less than 30 days before each such sinking fund payment date, the Trustee shall select the Securities to be redeemed upon such sinking fund payment date in the manner specified in Section 1103 and cause notice of the redemption thereof to be given in the name of and at the expense of the Company in the manner provided in Section 1104. Such notice having been duly given, the redemption of such Securities shall be made upon the terms and in the manner stated in Sections 1106 and 1107. ARTICLE THIRTEEN Meetings of Holders of Securities SECTION 1301. Purposes for Which Meetings May Be Called.

ARTICLE FOURTEEN SUBORDINATION SECTION 1401. Securities Subordinate to Senior Indebtedness. Unless otherwise specified as contemplated by Section 301, the Securities shall be subordinated to Senior Indebtedness as set forth in this Article Fourteen. The Company covenants and agrees, and each Holder of a Security of any series by such Holder's acceptance thereof likewise covenants and agrees, that, to the extent and in the manner hereinafter set forth in this Article Fourteen, the indebtedness represented by the Securities of such series and the payment of the principal amount, interest and such other amounts as provided for in Section 301, if any, in respect of each and all of the Securities of such series are hereby expressly made subordinate and subject in right of payment to the prior payment in full of all Senior Indebtedness; provided, however, that no provision of this Article Fourteen shall prevent the occurrence of any default or Event of Default hereunder. "Senior Indebtedness" means the principal of (and premium, if any) and interest on (including interest accruing after the filing of a petition initiating any proceeding pursuant to any Federal bankruptcy law or any other applicable Federal or State law, but only to the extent allowed or permitted to the holder of such Indebtedness of the Company against the bankruptcy or any other insolvency estate of the Company in such proceeding) and other amounts due on or in connection with any Indebtedness of the Company incurred, assumed or guaranteed by the Company, whether outstanding on the date of the Indenture or thereafter incurred, assumed or guaranteed and all renewals, extensions and refundings of any such Indebtedness of the Company; provided, however, that the following will not constitute Senior Indebtedness: (a) any Indebtedness of the Company as to which, in the instrument creating the same or evidencing the same or pursuant to which the same is outstanding, it is expressly provided that such Indebtedness of the Company shall be subordinated to or pari passu with the Securities; (b) Indebtedness of the Company in respect of the Securities; (c) any Indebtedness of the Company constituting trade accounts payable arising in the ordinary course of business; (d) any Indebtedness of the Company initially issued to any other Oxy Capital Trust in connection with an issuance by such Oxy Capital Trust of preferred securities or other securities similar to preferred securities; and (e) any Indebtedness of the Company to any Subsidiary of the Company. 66

Upon any distribution of assets of the Company in the event of: (a) any insolvency or bankruptcy case or proceeding, or any receivership, liquidation, reorganization or other similar case or proceeding in connection therewith, relative to the Company or to its creditors, as such, or to its assets, or (b) any liquidation, dissolution or other winding up of the Company, whether voluntary or involuntary and whether or not involving insolvency or bankruptcy, or (c) any assignment for the benefit of creditors or any other marshalling of assets and liabilities of the Company, then and in such event (1) the holders of Senior Indebtedness shall be entitled to receive payment in full of all amounts due or to become due on or in respect of all Senior Indebtedness, or provision shall be made for such payment in cash, before the Holders of the Securities of any series are entitled to receive any payment on account of the principal amount, interest or such other amounts as may be provided for in Section 301, if any, in respect of the Securities of such series; and (2) any payment or distribution of assets of the Company of any kind or character, whether in cash, property or securities, by set-off or otherwise, to which the Holders or the Trustee would be entitled but for the provisions of this Article Fourteen, including any such payment or distribution which may be payable or deliverable by reason of the payment of any other Indebtedness of the Company being subordinated to the payment of the Securities of such series, shall be paid by the liquidating trustee or agent or other person making such payment or distribution, whether a trustee in bankruptcy, a receiver or liquidating trustee or otherwise, directly to the holders of Senior Indebtedness or their representative or representatives or to the trustee or trustees under any indenture under which any instruments evidencing any of such Senior Indebtedness may have been issued, ratably according to the aggregate amounts remaining unpaid on account of the principal of, and premium, if any, and interest on the Senior Indebtedness held or represented by each, to the extent necessary to make payment in full of all Senior Indebtedness remaining unpaid, after giving effect to any concurrent payment or distribution to the holders of such Senior Indebtedness. In the event that, notwithstanding the foregoing provisions of this Section 1402, the Trustee or the Holder of any Security of any series shall receive any payment or distribution of assets of the Company of any kind or character, whether in cash, property or securities, including any such payment or distribution which may be payable or deliverable by reason of the payment of any other Indebtedness of the Company being subordinated to the payment of the Securities of such series, 67

before all Senior Indebtedness is paid in full or payment thereof provided for, and if such fact shall then have been made known to the Trustee as provided in Section 1410, or, as the case may be, such Holder, then and in such event such payment or distribution shall be paid over or delivered forthwith to the trustee in bankruptcy, receiver, liquidating trustee, custodian, assignee, agent or other person making payment or distribution of assets of the Company for application to the payment of all Senior Indebtedness remaining unpaid, to the extent necessary to pay all Senior Indebtedness in full, after giving effect to any concurrent payment or distribution to or for the holders of Senior Indebtedness. For purposes of this Article Fourteen only, the words "cash, property or securities," or any combination thereof, shall not be deemed to include shares of capital stock of the Company as reorganized or readjusted, or securities of the Company or any other corporation provided for by a plan of reorganization or readjustment the payment of which is subordinated, at least to the extent provided in this Article Fourteen with respect to the Securities, to the payment of all Senior Indebtedness which may at the time be outstanding; provided, however, that (i) Senior Indebtedness is assumed by the new corporation, if any, resulting from any such reorganization or readjustment, and (ii) the rights of the holders of the Senior Indebtedness are not, without the consent of such holders, altered, in any manner adverse to such holders, by such reorganization or readjustment. The consolidation of the Company with, or the merger of the Company into, another corporation or the liquidation or dissolution of the Company following the conveyance or transfer of all or substantially all of its assets to another person upon the terms and conditions set forth in Article VIII shall not be deemed a dissolution, winding up, liquidation, reorganization, assignment for the benefit of creditors or marshalling of assets and liabilities of the Company for the purposes of this Section 1402 if the corporation formed by such consolidation or into which the Company is merged or the person which acquires by conveyance or transfer all or substantially all of the assets of the Company, as the case may be, shall, as a part of such consolidation, merger, conveyance or transfer, comply with the conditions set forth in Article VIII. SECTION 1403. Prior Payment to Senior Indebtedness upon Acceleration of Securities. In the event that any Securities of any series are declared due and payable before their Stated Maturity, then and in such event the holders of Senior Indebtedness shall be entitled to receive payment in full of all amounts due or to become due on or in respect of all Senior Indebtedness or provision shall be made for such payment in cash, before the Holders of the Securities of such series are entitled to receive any payment (including any payment which may be payable by reason of the payment of any other indebtedness of the Company being subordinated to the payment of the Securities of such series) by the Company on account of the principal of (or premium, if any) or interest or other amounts on Securities of such series or on account of the purchase or other acquisition of Securities of such series. In the event that, notwithstanding the foregoing, the Company shall make any payment to the Trustee or the Holder of any Securities of any series prohibited by the foregoing provisions of this Section 1403, and if such facts then shall have been known or thereafter shall have been made known 68

to the Trustee (as provided in Section 1410) or to such Holder, as the case may be, pursuant to the terms of this Indenture, then and in such event such payment shall be paid over and delivered forthwith to the Company by or on behalf of the person holding such payment for the benefit of the holders of Senior Indebtedness. The provisions of this Section 1403 shall not apply to any payment with respect to which Section 1402 would be applicable. SECTION 1404. Default in Senior Indebtedness. In the event and during the continuation of any default by the Company in the payment of principal, premium, if any, interest or any other payment due on any Senior Indebtedness of the Company, as the case may be, beyond any applicable grace period with respect thereto, or in the event that the maturity of any Senior Indebtedness of the Company has been accelerated because of a default, then, in any such case, no payment shall be made by the Company with respect to the principal (including redemption payments, if any) of, premium, if any, or interest or other amounts on the Securities until such default is cured or waived or ceases to exist or any such acceleration or demand for payment has been rescinded. SECTION 1405. Payment Permitted if No Default. Nothing contained in this Article Fourteen or elsewhere in this Indenture or in any of the Securities shall prevent (a) the Company, at any time except during the pendency of any case, proceeding, dissolution, liquidation or other winding up, assignment for the benefit of creditors or other marshalling of assets and liabilities of the Company referred to in Section 1402 or under the conditions described in Sections 1403 or 1404, from making payments at any time of the principal amount, interest or such other amounts as may be provided for in Section 301, if any, as the case may be, in respect of the Securities, or (b) the application by the Trustee or the retention by any Holder of any money deposited with it hereunder to the payment of or on account of the principal amount, interest or such other amounts as may be provided for in Section 301, if any, as the case may be, in respect of the Securities if the Trustee did not have, at the time provided in the proviso to the first paragraph of Section 1410, notice that such payment would have been prohibited by the provisions of this Article Fourteen. SECTION 1406. Subrogation Rights of Holders of Senior Indebtedness. Subject to the payment in full of all Senior Indebtedness, the Holders of the Securities of any series shall be subrogated to the extent of the payments or distributions made to the holders of such Senior Indebtedness pursuant to the provisions of this Article Fourteen to the rights of the holders of such Senior Indebtedness to receive payments or distributions of cash, property or securities applicable to the Senior Indebtedness until the principal amount, interest or such other amounts as provided for in Section 301, if any, as the case may be, in respect of the Securities of such series shall be paid in full. For purposes of such subrogation, no payments or distributions to the holders of the 69

Senior Indebtedness of any cash, property or securities to which the Holders of the Securities of such series or the Trustee would be entitled except for the provisions of this Article Fourteen, and no payments pursuant to the provisions of this Article Fourteen to the Company or to the holders of Senior Indebtedness by Holders of the Securities of such series or the Trustee, shall, as between the Company, its creditors other than holders of Senior Indebtedness and the Holders of the Securities of such series, be deemed to be a payment or distribution by the Company to or on account of the Senior Indebtedness. SECTION 1407. Provision Solely to Define Relative Rights. The provisions of this Article Fourteen are and are intended solely for the purpose of defining the relative rights of the Holders of the Securities of any series, on one hand, and the holders of Senior Indebtedness, on the other hand. Nothing contained in this Article Fourteen or elsewhere in this Indenture or in the Securities of any series is intended to or shall: (a) impair, as between the Company and the Holders of the Securities of such series, the obligation of the Company, which is absolute and unconditional, to pay to the Holders of the Securities of such series the principal amount, interest or such other amounts as may be provided for in Section 301, if any, as the case may be, in respect of the Securities of such series as and when the same shall become due and payable in accordance with the terms of the Securities of such series and this Indenture and which, subject to the rights under this Article Fourteen of the holders of Senior Indebtedness, is intended to rank equally with all other general obligations of the Company; or (b) affect the relative rights against the Company of the Holders of the Securities of such series and creditors of the Company other than holders of Senior Indebtedness; or (c) prevent the Trustee or the Holder of any Security of such series from exercising all remedies otherwise permitted by applicable law upon default under this Indenture, subject to the rights, if any, under this Article Fourteen of the holders of Senior Indebtedness to receive cash, property or securities otherwise payable or deliverable to the Trustee or such Holder. SECTION 1408. Trustee to Effectuate Subordination. Each Holder of a Security by such Holder's acceptance thereof authorizes and directs the Trustee on such Holder's behalf to take such action as may be necessary or appropriate to effectuate the subordination provided in this Article Fourteen and appoints the Trustee such Holder's attorney-in-fact for any and all such purposes. SECTION 1409. No Waiver of Subordination Provisions. No right of any present or future holder of any Senior Indebtedness to enforce subordination as herein provided shall at any time in any way be prejudiced or impaired by any act or failure to act on the part of the Company or by any act or failure to act, in good faith, by any such holder, or by 70

any noncompliance by the Company with the terms, provisions and covenants of this Indenture, regardless of any knowledge thereof any such holder may have or be otherwise charged with. Without in any way limiting the generality of the foregoing paragraph, the holders of Senior Indebtedness may, at any time and from time to time, without the consent of, or notice to, the Trustee or the Holders of the Securities of any series, without incurring responsibility to the Holders of the Securities of such series and without impairing or releasing the subordination provided in this Article Fourteen or the obligations hereunder of the Holders of the Securities of such series to the holders of Senior Indebtedness, do any one or more of the following: (i) change the manner, place or terms of payment or extend the time of payment of, or renew or alter, Senior Indebtedness, or otherwise amend or supplement in any manner Senior Indebtedness or any instrument evidencing the same or any agreement under which Senior Indebtedness is outstanding; (ii) sell, exchange, release or otherwise dispose of any property pledged, mortgaged or otherwise securing Senior Indebtedness; (iii) release any person liable in any manner for the collection of Senior Indebtedness and (iv) exercise or refrain from exercising any rights against the Company or any other person. SECTION 1410. Notice to Trustee. The Company shall give prompt written notice to the Trustee of any fact known to the Company which would prohibit the making of any payment to or by the Trustee in respect of the Securities of any series. Failure to give such notice shall not affect the subordination of the Securities of such series to Senior Indebtedness. Notwithstanding the provisions of this Article Fourteen or any other provision of this Indenture, the Trustee shall not be charged with knowledge of the existence of any facts which would prohibit the making of any payment to or by the Trustee in respect of the Securities of such series, unless and until the Trustee shall have received written notice thereof in accordance with Section 105 from the Company or a holder of Senior Indebtedness or from any trustee or agent therefor; and, prior to the receipt of any such written notice, the Trustee, subject to the provisions of Section 601, shall be entitled in all respects to assume that no such facts exist; provided, however, that if the Trustee shall not have received, at least three Business Days prior to the date upon which by the terms hereof any such money may become payable for any purpose (including, without limitation, the payment of the principal amount, interest or such other amounts as may be provided for in Section 301, if any, as the case may be, in respect of any Security of such series), the notice with respect to such money provided for in this Section 1410, then, anything herein contained to the contrary notwithstanding, the Trustee shall have full power and authority to receive such money and to apply the same to the purpose for which such money was received and shall not be affected by any notice to the contrary which may be received by it within three Business Days prior to such date. Subject to the provisions of Section 601, the Trustee shall be entitled to rely on the delivery to it of a written notice by a person representing himself to be a holder of Senior Indebtedness (or a trustee or agent on behalf of such holder) to establish that such notice has been given by a holder of Senior Indebtedness (or a trustee or agent on behalf of any such holder). In the event that the Trustee determines in good faith that further evidence is required with respect to the right of any person as 71

a holder of Senior Indebtedness to participate in any payment or distribution pursuant to this Article Fourteen, the Trustee may request such person to furnish evidence to the reasonable satisfaction of the Trustee as to the amount of Senior Indebtedness held by such person, the extent to which such person is entitled to participate in such payment or distribution and any other facts pertinent to the rights of such person under this Article Fourteen, and if such evidence is not furnished, the Trustee may defer any payment which it may be required to make for the benefit of such person pursuant to the terms of this Indenture pending judicial determination as to the right of such person to receive such payment. SECTION 1411. Reliance on Judicial Order or Certificate of Liquidating Agent. Upon any payment or distribution of assets of the Company referred to in this Article Fourteen, the Trustee, subject to the provisions of Section 601, and the Holders of the Securities of any series shall be entitled to rely upon any order or decree entered by any court of competent jurisdiction in which such insolvency, bankruptcy, receivership, liquidation, reorganization, dissolution, winding up or similar case or proceeding is pending, or a certificate of the trustee in bankruptcy, liquidating trustee, custodian, receiver, assignee for the benefit of creditors, agent or other person making such payment or distribution, delivered to the Trustee or to the Holders of Securities of such series, for the purpose of ascertaining the persons entitled to participate in such payment or distribution, the holders of Senior Indebtedness and other indebtedness of the Company, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Article Fourteen. SECTION 1412. Trustee Not Fiduciary for Holders of Senior Indebtedness. The Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior Indebtedness and shall not be liable to any such holders if the Trustee shall in good faith mistakenly pay over or distribute to Holders of Securities or to the Company or to any other person cash, property or securities to which any holders of Senior Indebtedness shall be entitled by virtue of this Article Fourteen or otherwise. The Trustee shall not be charged with knowledge of the existence of Senior Indebtedness or of any facts that would prohibit any payment hereunder unless the Trustee shall have received notice in accordance with Section 105. With respect to the holders of Senior Indebtedness, the Trustee undertakes to perform or to observe only such of its covenants or obligations as are specifically set forth in this Article Fourteen and no implied covenants or obligations with respect to holders of Senior Indebtedness shall be read into this Indenture against the Trustee. SECTION 1413. Rights of Trustee as Holder of Senior Indebtedness; Preservation of Trustee's Rights. The Trustee in its individual capacity shall be entitled to all the rights set forth in this Article Fourteen with respect to any Senior Indebtedness which may at any time be held by it, to the same 72

extent as any other holder of Senior Indebtedness, and nothing in this Indenture shall deprive the Trustee of any of its rights as such holder. Nothing in this Article Fourteen shall apply to claims of, or payments to, the Trustee under or pursuant to Section 607. SECTION 1414. Article Fourteen Applicable to Paying Agents. The term "Trustee" as used in this Article Fourteen shall (unless the context otherwise requires) be construed as extending to and including the Paying Agent within its meaning as fully for all intents and purposes as if the Paying Agent were named in this Article Fourteen in addition to or in place of the Trustee; provided, however, that Sections 1410 and 1412 shall not apply to the Company or any Affiliate of the Company if it or such Affiliate acts as Paying Agent. 73

In case an Event of Default has occurred (that has not been cured or waived pursuant to Section 2.06), the Preferred Guarantee Trustee shall exercise such of the rights and powers vested in it by 6

this Guarantee Agreement, and use the same degree of care and skill in their exercise or use, as a prudent person would exercise or use under the circumstances in the conduct of his or her own affairs.

EXHIBIT 4.4 OCCIDENTAL PETROLEUM CORPORATION -------------------------------- Officers' Certificate --------------------- Oxy Capital Trust I, a Delaware statutory business trust (the "Trust"), has offered to the public $525,000,000 aggregate liquidation amount of its 8.16% Trust Originated Preferred Securities (the "Preferred Securities"), representing undivided beneficial interests in the assets of the Trust and proposes to invest the proceeds from such offering, together with the proceeds of the issuance and sale by the Trust to the Company of $16,237,125 aggregate liquidation amount of its Common Securities (the "Common Securities" and, together with the Preferred Securities, the "Trust Securities"), in $541,237,125 aggregate principal amount of the Notes referred to below issued under the Indenture (as defined below). The Trust Securities will be issued pursuant to the terms of an Amended and Restated Declaration of Trust of the Trust, dated as of January 20, 1999 (the "Declaration"), among the Regular Trustees (as defined therein) (the "Regular Trustees"), the Delaware Trustee (as defined therein) (the "Delaware Trustee"), the Property Trustee (as defined therein) (the "Property Trustee"), Occidental Petroleum Corporation, a Delaware corporation (the "Company") and the holders from time to time of the Trust Securities.

Compliance with Covenants and Conditions Precedent. All covenants and conditions precedent provided for in the Indenture relating to the establishment of the series of Securities have been complied with. 3. Terms. The terms of the series of Securities established pursuant to this Officers' Certificate shall be as follows: (i) Title. The title of the series of Securities is the "8.16% Subordinated Deferrable Interest Notes due 2039" (the "Notes"). (ii) Aggregate Principal Amount. The aggregate principal amount of the Notes which may be authenticated and delivered pursuant to the Indenture (except for Notes authenticated and delivered upon registration of transfer of, or in exchange for, or in lieu of, other Notes pursuant to Sections 304, 305, 306, 906 and 1107 of the Indenture) is $541,237,125. (iii) Registered Securities in Book-Entry Form. Except as provided in paragraph (xxiii) below, the Notes will be issued in fully registered certificated form

without interest coupons. Pursuant to paragraph (xiii) below, the Notes may be issued in book-entry form ("Book-Entry Notes") and represented by one or more global notes (the "Global Notes") in fully registered form, without coupons. The initial Depositary with respect to the Global Notes will be The Depository Trust Company, as Depositary for the accounts of its participants. So long as the Depositary for a Global Note, or its nominee, is the registered owner of the Global Note, the Depositary or its nominee, as the case may be, will be considered the sole owner or holder of the Notes in book-entry form represented by such Global Note for all purposes under the Indenture. Book-Entry Notes will not be exchangeable for Notes in definitive form ("Definitive Notes") except that, if the Depositary with respect to any Global Note or Notes is at any time unwilling or unable to continue as Depositary and a successor Depositary is not appointed by the Company within 90 days, the Company will issue Definitive Notes in exchange for the Book-Entry Notes represented by any such Global Note or Notes. In addition, the Company may at any time and in its sole discretion determine not to have a Global Note or Notes, and, in such event, will issue Definitive Notes in exchange for the Book-Entry Notes represented by such Global Note or Notes in accordance with the provisions of Section 305 of the Indenture. 2

(iv) Persons to Whom Interest Payable. Interest will be payable to the Person in whose name a Note is registered at the close of business (whether or not a Business Day) on the Regular Record Date with respect to such Note, except for interest payable on a Note surrendered for redemption as set forth in paragraph (ix) below. (v) Stated Maturity. The principal amount of the Notes will be payable on January 20, 2039, subject to earlier redemption as set forth in paragraph (ix) below. (vi) Rate of Interest; Interest Payment Dates; Regular Record Dates; Accrual of Interest. The Notes will bear interest at the rate of 8.16% per annum (the "Coupon Rate"). Interest on the Notes will be payable quarterly in arrears on March 31, June 30, September 30 and December 31 of each year (each, an "Interest Payment Date"), commencing on March 31, 1999. In respect of any Notes of which the Property Trustee is the registered holder or any Notes which are in book-entry only form, the Regular Record Date shall be one Business Day before the relevant Interest Payment Date. Notwithstanding the foregoing sentence, if the Preferred Securities are no longer in book-entry only form or a Dissolution Event has occurred and subsequent thereto the Notes are not represented by a Global Note pursuant to the provisions of Section 305(7) of the Indenture, the Regular Record Date will be the 15th day of the last month of each quarterly distribution period (whether or not a Business Day) next preceding such Interest Payment Date. The Notes will bear interest from January 20, 1999 or from the most recent Interest Payment Date to which interest has been paid or duly provided for until the principal thereof is paid or made available for payment. Interest payments shall be the amount of interest accrued from and including the most recent Interest Payment Date in respect of which interest has been paid or duly provided for (or from and including January 20, 1999 if no interest has been paid or duly provided for with respect to such Note), to but excluding the next succeeding Interest Payment Date. The amount of interest payable for any period will be computed on the basis of a 360-day year of twelve 30-day months. Except as provided in the following sentence, the amount of interest payable for any period shorter than a full quarterly period for which interest is computed, will be computed on the basis of the actual number of days elapsed per 30-day month. In the event that any date on which interest is payable on the Notes is not a Business Day, then payment of interest payable on such date will be made on the next succeeding day which is a Business Day (and without any interest or other payment in respect of any such delay), except that, if such Business Day is in the next succeeding 3

calendar year, such payment shall be made on the immediately preceding Business Day, in each case with the same force and effect as if made on such date. (vii) Additional Interest. If at any time while the Property Trustee is the holder of any Notes, the Trust or the Property Trustee is required to pay any taxes, duties assessments or governmental charges of whatever nature (other than withholding taxes) imposed by the United States, or any other taxing authority, then, in any such case, the Company will pay as additional interest ("Additional Interest") on the Notes held by the Property Trustee, such additional amounts as shall be required so that the net amounts received and retained by the Trust and the Property Trustee after paying such taxes, duties, assessments or other governmental charges will be equal to the amounts the Trust and the Property Trustee would have received had no such taxes, duties, assessments or other governmental charges been imposed. (viii) Place of Payment; Registration of Transfer and Exchange; Notices to Company. Payment of the principal of and interest on the Notes will be made at the Corporate Trust Office of the Trustee in the Borough of Manhattan, The City of New York, or at any other office or agency designated by the Company for such purpose; provided, however, that, at the option of the Company, payment of interest may be made by check mailed to the address of the Person entitled thereto as such address shall appear in the Security Register. Notwithstanding the foregoing, so long as the registered holder of any Notes is the Property Trustee, the payment of the principal of and interest (including Additional Interest, if any) on such Notes held by the Property Trustee will be made at such place and to such account as may be designated by the Property Trustee. The Notes may be presented for exchange and registration of transfer at the Corporate Trust Office of the Trustee in the Borough of Manhattan, The City of New York, or at the office of any transfer agent hereafter designated by the Company for such purpose. Notices and demands to or upon the Company in respect of the Notes and the Indenture may be served at Occidental Petroleum Corporation, 10889 Wilshire Boulevard, Los Angeles, California 90024, Attention: Vice President and Treasurer. (ix) Redemption. The Notes are not entitled to any mandatory redemption or sinking fund payments. (a) Optional Redemption: The Notes will be redeemable, in whole or from time to time in part, at the option of the Company at any time on or after January 20, 2004 at a redemption price equal to 100% of the principal amount per Note to be redeemed plus, in each case, accrued and unpaid interest thereon to the Redemption Date (the "Redemption Price"). (b) Special Event Redemption: If, at any time, a Tax Event or an Investment Company Event (each as defined below, and each a "Special Event") shall occur and be continuing, the Company shall 4

have the right to redeem the Notes in whole or in part, for cash within 90 days following the occurrence of such Special Event, at the Redemption Price. i. "Investment Company Event" means that the Trust shall have received an opinion of counsel experienced in practice under the Investment Company Act that, as a result of the occurrence of a change in law or regulation or a change in interpretation or application of law or regulation by any legislative body, court, governmental agency or regulatory authority (a "Change in 1940 Act Law"), there is more than an insubstantial risk that the Trust is or will be considered an investment company which is required to be registered under the Investment Company Act of 1940, as amended, which Change in 1940 Act Law becomes effective on or after January 13, 1999. ii. "Tax Event" means that the Trust shall have received an opinion of counsel experienced in such matters to the effect that on or after January 13, 1999, as a result of (a) any amendment to, or change (including any announced proposed change) in, the laws (or any regulations thereunder) of the United States or any political subdivision or taxing authority thereof or therein, or (b) any official or administrative pronouncement or action, or judicial decision, interpreting or applying such laws or regulations, where such change or amendment becomes effective, or such pronouncement, action or decision is announced or occurs, in each case on or after January 13, 1999, there is more than an insubstantial risk that (i) the Trust is or will be within 90 days of the date of such opinion, subject to United States federal income tax with respect to interest accrued or received on the Notes, (ii) the Trust is, or will be within 90 days of the date of such opinion, subject to more than a minimal amount of other taxes, duties, assessments or other governmental charges, or (iii) interest payable by the Company to the Trust on the Notes is not, or within 90 days of the date of such opinion will not be, deductible, in whole or in part, by the Company for United States federal income tax purposes. (c) Notice of any redemption will be mailed at least 30 days but not more than 60 days before the redemption date to each Holder of the Notes to be redeemed. Unless the Company defaults in payment of the Redemption Price, on and after the redemption date, interest will cease to accrue on the Notes or portions thereof called for redemption. If less than all of the Notes are to be redeemed, the Notes (or portions thereof) to be redeemed shall be selected by the Trustee by such method as the Trustee shall deem fair and appropriate, provided that if, at the time of redemption, the Notes are registered as a Global Note, the Depositary shall determine the principal amount of such Notes held by each holder to be redeemed in accordance with its procedures. (d) If a partial redemption of the Notes would result in the delisting of the Preferred Securities from any national securities exchange or other organization on which 5

the Preferred Securities are then listed, the Company shall not be permitted to effect such partial redemption and may only redeem the Notes in whole. (x) Extension of Interest Payment Period. (a) Right to Extend. The Company shall have the right, at any time, and from time to time, during the term of the Notes to extend the interest payment period of such Notes for up to 20 consecutive quarterly periods (an "Extended Interest Payment Period"), provided no Event of Default has occurred and is continuing with respect to the Notes. To the extent permitted by applicable law, interest, the payment of which has been deferred because of the extension of the interest payment period pursuant to this paragraph, will bear interest thereon at the Coupon Rate for each quarterly period of the Extended Interest Payment Period. At the end of the Extended Interest Payment Period, the Company shall pay all interest accrued and unpaid on the Notes including any Additional Interest ("Deferred Interest") which shall be payable to the holders of the Notes in whose names the Notes are registered in the Security Register on the first Regular Record Date after the end of the Extended Interest Payment Period. Before the termination of any Extended Interest Payment Period, the Company may further extend such period, provided that such period together with all such further extensions thereof shall not exceed 20 consecutive quarterly periods. Upon the termination of any Extended Interest Payment Period and upon the payment of all Deferred Interest then due, the Company may select a new Extended Interest Payment Period, subject to the foregoing requirements. No interest shall be due and payable during an Extended Interest Payment Period, except at the end thereof. (b) Notice of Extension. i. If the Property Trustee is the only registered holder of the Notes at the time the Company selects an Extended Interest Payment Period, the Company shall give written notice to both the Regular Trustees and the Property Trustee of its selection of such Extended Interest Payment Period one Business Day before the earlier of (i) the next succeeding date on which Distributions on the Trust Securities are payable or (ii) the date the Trust is required to give notice of the record date or the date such Distributions are payable to the New York Stock Exchange or other applicable self-regulatory organization or to holders of the Preferred Securities, but in any event at least one Business Day before such record date. ii. If the Property Trustee is not the only holder of the Notes at the time the Company selects an Extended Interest Payment Period, the Company shall give the holders of the Notes written notice of its selection of such Extended Interest Payment Period ten Business Days before the earlier of (i) the next succeeding Interest Payment Date or (ii) the date the Company is required to give notice of the record or payment date of such interest payment to the New York 6

Stock Exchange or other applicable self-regulatory organization or to holders of the Notes. iii. The quarterly period in which any notice is given pursuant to paragraphs (a) or (b) of this subparagraph (ii) shall be counted as one of the 20 quarterly periods permitted in the maximum Extended Interest Payment Period permitted under this paragraph (x). (xi) Limitation of Transactions. If Notes are issued to the Trust or a trustee of the Trust and (i) there shall have occurred any event that would constitute an Event of Default or (ii) the Company shall be in default with respect of its payment or other obligations under the Preferred Securities Guarantee Agreement, dated as of January 20, 1999, between the Company and The Bank of New York or (iii) the Company shall have given notice of its election to defer payments of interest on the Notes by extending the interest payment period as provided in paragraph (xi) above, then (a) the Company will not declare or pay any dividend on, or make any distributions with respect to, or redeem, purchase, acquire or make a liquidation payment with respect to, any of its capital stock, and (b) the Company will not make any payment of interest, principal or premium, if any, on or repay, repurchase or redeem any debt securities (including guarantees) of the Company which rank pari passu with or junior to the Notes; provided, that, clause (a) above does not apply to (i) any stock dividends paid by the Company where the dividend stock is the same as that on which the dividend is being paid, (ii) purchases or acquisitions by the Company of shares of its common stock in connection with the satisfaction by the Company or any of its subsidiaries of their respective obligations under any benefit plans for directors, officers, agents or employees or the Company's dividend reinvestment or director, officer, agent or employee stock purchase plans, (iii) a reclassification of the Company's capital stock or the exchange or conversion of one class or series of its capital stock for another class or series of its capital stock, (iv) the purchase of fractional interests in shares of the Company's capital stock pursuant to the conversion or exchange provisions of such capital stock or security being converted or exchanged for capital stock, (v) dividends or distributions in shares of, or options, warrants or rights to subscribe for or purchase shares of, the Company's capital stock or (vi) any declaration by the Company of a dividend in connection with the implementation or extension of a stockholders' rights plan, or the issuance of stock under any such plan (including any such existing plan) in the future or the redemption or repurchase of any such rights pursuant thereto. (xii) Denominations. The Notes are issuable in denominations of $25 and integral multiples thereof. (xiii) Agreement to Subordinate. The Company covenants and agrees, and each holder of Notes issued hereunder by such holder's acceptance thereof likewise covenants and agrees, that all Notes shall be issued subject to the provisions of Article 7

FOURTEEN of the Indenture; and each holder of a Note, whether upon original issue or upon transfer or assignment thereof, accepts and agrees to be bound by such provisions. (xiv) Security Register; Paying Agent. The Security Register for the Notes will be initially maintained at the Corporate Trust Office of the Trustee. The Company hereby appoints the Trustee as the initial Paying Agent. (xv) Covenants as to the Trust. For so long as the Trust Securities remain outstanding, the Company will (i) maintain 100% direct or indirect ownership of the Common Securities of the Trust; provided, however, that any permitted successor of the Company under the Indenture may succeed to the Company's ownership of the Common Securities and (ii) use its reasonable efforts to cause the Trust (A) to remain a statutory business trust, except in connection with a distribution of Notes as provided in the Declaration the redemption of all of the Trust Securities or certain mergers, consolidations or amalgamations permitted by the Declaration, and (B) to continue to be treated as a grantor trust for United States federal income tax purposes. (xvi) Events of Default. For the Notes only, a valid extension of the interest payment period in accordance with paragraph (x) hereof shall not constitute a Default or Event of Default under the Indenture. For the Notes only, the voluntary or involuntary dissolution, winding-up or termination of the Trust, except in connection with (a) the distribution of the Notes to the holders of the Trust Securities in liquidation of the Trust, (b) the redemption of all the Trust Securities, or (c) mergers, consolidations or amalgamations, each as permitted by the Declaration, shall constitute an Event of Default. (xvii) Waiver of Past Defaults. For the Notes only, any waiver pursuant to Section 513 of the Indenture or any modification of such a waiver shall not be effective until the holders of a majority in liquidation amount of Trust Securities shall have consented to such waiver; provided, however, that if the consent of the holder of each Outstanding Security is required, such waiver shall not be effective until each holder of the Trust Securities shall have consented to such waiver. (xviii) Listing on Exchanges. If the Notes are to be issued as a Global Note in connection with the distribution of the Notes to the holders of the Preferred Securities upon a Dissolution Event, the Company will use its best efforts to list such Notes on the New York Stock Exchange or on such other exchange as the Preferred Securities are then listed. (xix) Direct Action. The Company and the Trustee acknowledge that pursuant to the Declaration, the holders of Preferred Securities are entitled, in the circumstances and subject to the limitations set forth therein, to commence a Direct Action (as defined therein) with respect to any Event of Default under the Indenture. 8

(xx) Supplemental Indentures. For the Notes only, any supplemental indenture referred to in Section 902 of the Indenture shall not be effective until the holders of a majority in liquidation amount of Trust Securities shall have consented to such supplemental indenture; provided, however, that if the consent of the holder of each Outstanding Security is required, such supplemental indenture shall not be effective until each holder of the Trust Securities shall have consented to such supplemental indenture. (xxi) Form. The Notes will be in substantially the form set forth in Exhibit A attached hereto and may have such other terms as are provided in such form. (xxii) Payment of Expenses. In connection with the offering, sale and issuance of the Notes to the Property Trustee in connection with the sale of the Trust Securities by the Trust, and the operation of the Trust, the Company shall: (a) pay all costs and expenses relating to the offering, sale and issuance of the Notes, including commissions to the underwriters payable pursuant to the Underwriting Agreement dated January 13, 1999 among the Company, the Trust and the underwriters named therein and compensation of the Trustee under the Indenture in accordance with the provisions of Section 607 of the Indenture; (b) pay all costs and expenses of the Trust (including, but not limited to, costs and expenses relating to the organization of the Trust, the offering, sale and issuance of the Trust Securities (including commissions to the underwriters in connection therewith), the fees and expenses of the trustees of the Trust, the costs and expenses relating to the operation of the Trust, including without limitation, costs and expenses of accountants, attorneys, statistical or bookkeeping services, expenses for printing and engraving and computing or accounting equipment, paying agent(s), registrar(s), transfer agent(s), duplicating, travel and telephone and other telecommunications expenses and costs and expenses incurred in connection with the acquisition, financing and disposition of Trust assets); and (c) pay any and all taxes (other than United States withholding taxes attributable to the Trust or its assets) and all liabilities, costs and expenses with respect to such taxes of the Trust. (xxiii) Dissolution Event. "Dissolution Event" means that as a result of an election by the Company, the Trust is to be dissolved in accordance with the Declaration and the Notes held by the Property Trustee are to be distributed to the holders of the Trust Securities pro rata in accordance with the Declaration. In connection with a Dissolution Event: (a) Definitive Notes may be presented to the Trustee by the Property Trustee in exchange for a Global Note in an aggregate principal amount equal to all Definitive Notes Outstanding to be registered in the name of the Depositary, or its nominee, and delivered by the Trustee to the Depositary for crediting to the accounts of its participants pursuant to the instructions of the Regular Trustees. The Company upon any such presentation shall execute a Global Note in such aggregate principal amount and deliver the same to the Trustee for authentication and delivery in accordance with the Indenture and this Officers' Certificate. Payments on the Notes issued as a Global Note will be made to the Depositary; and (b) if any Preferred Securities are held in non book-entry certificated form, Definitive Notes may be presented to the Trustee by the Property Trustee and any Preferred Security Certificate which represents Preferred Securities other than Preferred Securities held by the Depositary or its nominee ("Non Book-Entry Preferred Securities") will be deemed to represent beneficial interests in Notes presented to the Trustee by the Property Trustee having an aggregate principal amount equal to the aggregate liquidation amount of the Non Book-Entry Preferred Securities until such Preferred Security Certificates are presented to the Security Registrar for transfer or reissuance at which time such Preferred Security Certificate will be cancelled and a Note registered in the name of the holder of the Preferred Security Certificate or the transferee of the holder of such Preferred Security Certificate as the case may be, with an aggregate principal amount equal to the aggregate liquidation amount of the Preferred Security Certificate cancelled will be executed by the Company and delivered to the Trustee for authentication and delivery in accordance with the Indenture and this Officers' Certificate. On issue of such Notes, Notes with an equivalent aggregate principal amount that were presented by the Property Trustee to the Trustee will be deemed to have been cancelled. Each of the undersigned, for himself, states that he has read and is familiar with the provisions of Article Two of the Indenture relating to the establishment of the form of Security representing a series of Securities thereunder and Article Three of the Indenture relating to the establishment of a series of Securities thereunder and, in each case, the definitions therein relating thereto; that he is generally familiar with the other provisions of the Indenture and with the affairs of the Company and its acts and proceedings and that the statements and opinions made by him in this Certificate are based upon such familiarity; and that, in his opinion, he has made such 9

examination or investigation as is necessary to enable him to express an informed opinion as to whether or not the covenants and conditions referred to above have been complied with. Insofar as this Certificate relates to legal matters it is based, as provided for in Section 103 of the Indenture, upon the Opinion of Counsel delivered to the Trustee contemporaneously herewith pursuant to Section 303 of the Indenture and relating to the Notes. 10

THE BANK OF NEW YORK, as Trustee By:______________________________ Authorized Signatory 1

OCCIDENTAL PETROLEUM CORPORATION, a corporation duly organized and existing under the laws of the State of Delaware (herein referred to as the "Company"), for value received, hereby promises to pay to The Bank of New York, as Property Trustee of Oxy Capital Trust I (the "Trust"), or registered assigns, the Principal Amount specified above on the Maturity Date specified above (unless and to the extent earlier redeemed or repaid prior to such Maturity Date) and to pay interest thereon from January 20, 1999 or from the most recent Interest Payment Date to which interest has been paid or duly provided for, quarterly (subject to deferral as set forth herein) in arrears on March 31, June 30, September 30 and December 31, in each year, commencing with the first Interest Payment Date next succeeding the Original Issue Date, at the rate per annum specified above, until the principal hereof is paid or made available for payment. Interest payments for this Note will include interest accrued to but excluding each Interest Payment Date. The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided in the Indenture (as defined below), be paid to the Person in whose name this Note (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date, which shall be the close of business on the Business Day next preceding such Interest Payment Date if this Note is held by the Property Trustee or if this Note is in book-entry only form. Notwithstanding the foregoing sentence, if the Preferred Securities of the Trust are no longer in book-entry only form or a Dissolution Event has occurred and subsequent thereto this Note is not a Global Note pursuant to the provisions of Section 305(7) of the Indenture, such regular record date shall be the close of business on the 15/th/ day next preceding such Interest Payment Date. If any Interest Payment Date or Maturity with respect to this Note falls on a day that is not a Business Day, the payment due on such Interest Payment Date or at Maturity will be made on the following day that is a Business Day as if it were made on the date such payment was due and no interest shall accrue on the amount so payable for the period from and after such Interest Payment Date or Maturity, as the case may be. Except as otherwise provided in the Indenture, any interest not punctually paid or duly provided for on any Interest Payment Date (herein called "Defaulted Interest") will forthwith cease to be payable to the Holder on the Regular Record Date with respect to such Interest Payment Date by virtue of having been such Holder and may either (1) be paid to the Person in whose name this Note (or one or more Predecessor Securities) is registered at the close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Trustee (as defined below), notice of which shall be given to Holders of Notes not less than 10 days prior to such Special Record Date, or (2) be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Notes may be listed, and upon such notice as may be required by such exchange, all as more fully provided in the Indenture. Payment of the principal of and interest, if any, on this Note will be made at the Corporate Trust Office of the Trustee or at the office or agency of the Trustee maintained for that purpose in the Borough of Manhattan, The City of New York, and at any other office or agency maintained by the Company for such purpose, in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts; provided, however, that at the option of the Company, payment of interest may be made by check mailed to the address of the Person entitled thereto as such address shall appear in the Security Register; and provided, further, that the Holder of this Note shall be entitled to receive payments of principal of and interest, if any, on this Note by wire transfer of immediately available funds if appropriate wire transfer instructions have been received in writing by the Trustee not less than l5 days prior to the applicable payment date. Notwithstanding the foregoing, so long as the Holder of this Note is the Property Trustee, the payment of the principal of and interest on this Note will be made at such place and to such account as may be designated by the Property Trustee. The indebtedness evidenced by this Note is, to the extent provided in the Indenture, subordinate and junior in right of payment to the prior payment in full of all Senior Indebtedness, and this Note is issued subject to the provisions of the Indenture with respect thereto. Each Holder of this Note, by 2

accepting the same, (a) agrees to and shall be bound by such provisions, (b) authorizes and directs the Trustee on his or her behalf to take such action as may be necessary or appropriate to acknowledge or effectuate the subordination so provided and (c) appoints the Trustee his or her attorney-in-fact for any and all such purposes. Each Holder hereof, by his or her acceptance hereof, hereby waives all notice of the acceptance of the subordination provisions contained herein and in the Indenture by each holder of Senior Indebtedness, whether now outstanding or hereafter incurred, and waives reliance by each such Holder upon said provisions. Reference is hereby made to the further provisions of this Note set forth below, which further provisions shall for all purposes have the same effect as if set forth at this place. Unless the certificate of authentication hereon has been executed by the Trustee or its duly appointed co-authenticating agent by manual signature, this Note shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose. This Note is one of a duly authorized issue of securities (herein called the "Securities") of the Company (which term includes any successor corporation under the Indenture hereinafter referred to) issued and to be issued pursuant to such Indenture. This Note is one of a series designated by the Company as its 8.16% Subordinated Deferrable Interest Notes due 2039 (the "Notes"), limited in aggregate principal amount to $541,237,125. The Indenture does not limit the aggregate principal amount of other Securities which may be issued thereunder. The Company issued this Note pursuant to an Indenture, dated as of January 20, 1999 (herein called the "Indenture" which term, for the purpose of this Note, shall include the Officers' Certificate dated January 20, 1999, delivered pursuant to Sections 201 and 301 of the Indenture), between the Company and The Bank of New York, as trustee (herein called the "Trustee," which term includes any successor trustee under the Indenture), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and Holders of the Notes and of the terms upon which the Notes are, and are to be, authenticated and delivered. The Notes are issuable as Registered Securities, without coupons, in denominations of $25 and any amount in excess thereof which is an integral multiple of $25. As provided in the Indenture and subject to certain limitations therein set forth, Notes are exchangeable for a like aggregate principal amount of Notes of like tenor of any authorized denomination, as requested by the Holder surrendering the same, upon surrender of the Note or Notes to be exchanged at any office or agency described below where Notes may be presented for registration of transfer. The Notes are redeemable, in whole or in part, without penalty, at the option of the Company (i) before January 20, 2004, within 90 days of the occurrence of a Special Event, at a Redemption Price equal to 100% of the principal amount of this Note plus any accrued and unpaid interest thereon to the date of such redemption and (ii) on or after January 20, 2004, at a Redemption Price equal to 100% of the principal amount per Note plus any accrued and unpaid interest thereon to the date of such redemption. Notice of any redemption will be mailed at least 30 days but not more than 60 days before the Redemption Date to each Holder of the Notes to be redeemed. Unless the Company defaults in payment of the Redemption Price, on and after the Redemption Date, interest will cease to accrue on the Notes or portions thereof called for redemption. If less than all of the Notes are to be redeemed, the Notes (or 3

portions thereof) to be redeemed will be selected by the Trustee by such method as the Trustee shall deem fair and appropriate; provided that if, at the time of redemption, the Notes are registered as a Global Note, the Depositary shall determine the principal amount of such Notes held by each Holder to be redeemed in accordance with its procedures. Notwithstanding the foregoing, installments of interest whose Stated Maturity is prior to the Redemption Date of any Note will be payable to the Holder of such Note, or one or more Predecessor Securities, of record at the close of business on the relevant Regular Record Date referred to above, all as provided in the Indenture. All notices of redemption shall state the Redemption Date, the Redemption Price, if fewer than all the Outstanding Notes are to be redeemed, the identification (and, in the case of partial redemption, the principal amounts) of the particular Notes to be redeemed, that on the Redemption Date the Redemption Price will become due and payable upon each Note, or portion thereof, to be redeemed, that interest on each Note, or portion thereof, called for redemption will cease to accrue on the Redemption Date and the place or places where Notes may be surrendered for redemption. In the event of redemption of this Note in part only, a new Note or Notes of like tenor for the unredeemed portion hereof will be issued in authorized denominations in the name of the Holder hereof upon the cancellation hereof. For all purposes of this Note and the Indenture, unless the context otherwise requires, all provisions relating to the redemption by the Company of this Note shall relate, in the case that this Note is redeemed or to be redeemed by the Company only in part, to that portion of the principal amount of this Note that has been or is to be redeemed. If an Event of Default with respect to the Notes shall occur and be continuing, the principal of the Notes may be declared due and payable in the manner and with the effect provided in the Indenture. The Indenture permits, in certain circumstances therein specified, the amendment thereof without the consent of the Holders of the Securities. The Indenture also permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations under the Indenture of the Company and the rights of Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in aggregate principal amount of the Securities at the time Outstanding of each series to be affected. The Indenture also contains provisions permitting the Holders of a majority in aggregate principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all the Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Note issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Note. No reference herein to the Indenture and no provision of this Note or, subject to the provisions for satisfaction and discharge in Article Four of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and interest on this Note at the times, place and rate, and in the coin or currency, herein prescribed. 4

The Company shall have the right at any time, and from time to time, during the term of the Notes to extend the interest payment period of such Notes for up to 20 consecutive quarterly periods (an "Extended Interest Payment Period") provided no Event of Default has occurred and is continuing with respect to the Notes, at the end of which period the Company shall pay all interest then accrued and unpaid (together with interest thereon at the rate specified for the Notes to the extent that payment of such interest is enforceable under applicable law). Before the termination of any such Extended Interest Payment Period, the Company may further extend such Extended Interest Payment Period, provided, however, that such Extended Interest Payment Period together with all such further extensions thereof shall not exceed 20 consecutive quarterly periods. At the termination of any such Extended Interest Payment Period and upon the payment of all accrued and unpaid interest and any additional amounts then due, the Company may select a new Extended Interest Payment Period. The Indenture permits the Company, by irrevocably depositing, in amounts and maturities sufficient to pay and discharge at the Stated Maturity or Redemption Date, as the case may be, the entire indebtedness on all Outstanding Notes, cash or U.S. Government Obligations with the Trustee in trust solely for the benefit of the Holders of all Outstanding Notes, to defease the Indenture with respect to such Notes, and upon such deposit the Company shall be deemed to have paid and discharged its entire indebtedness on such Notes. Thereafter, Holders would be able to look only to such trust fund for payment of principal and interest at the Stated Maturity or Redemption Date, as the case may be. As provided in the Indenture and subject to certain limitations therein set forth, the transfer of Notes is registrable in the Security Register, upon surrender of a Note for registration of transfer at the Corporate Trust Office of the Trustee or at the office or agency of the Trustee in the Borough of Manhattan, The City of New York, or at such other offices or agencies as the Company may designate, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Notes of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees. No service charge shall be made by the Company, the Trustee or the Security Registrar for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith (other than exchanges pursuant to Sections 304, 906 or 1107 of the Indenture, not involving any transfer). Prior to due presentment of this Note for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Note is registered as the owner hereof for all purposes, whether or not this Note be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary. This Note shall be governed by and construed in accordance with the laws of the State of New York including, without limitation, Section 5-1401 of the New York General Obligations Law. All undefined terms used in this Note which are defined in the Indenture shall have the meanings assigned to them in the Indenture. 5

We have also examined originals or copies, certified or otherwise identified to our satisfaction, of such records of the Company and the Trust and such agreements, certificates of public officials, certificates of officers, trustees or other representatives of the Company, the Trust and others, as applicable, and such other documents, certificates and records as we have deemed necessary or appropriate as a basis for the opinions set forth herein. In our examination, we have assumed the legal capacity of all natural persons, the genuineness of all signatures, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as certified, conformed or photostatic copies, and the authenticity of the originals of such latter documents. In making our examination of documents executed, or to be executed by parties other than the Company or the Trust, we have assumed that such parties had, or will have the power, corporate or other, to enter into and perform all obligations thereunder and have also assumed the due authorization by all requisite action, corporate or other, and execution and delivery by such parties of such documents and that such documents constitute, or will constitute, valid and binding obligations of such parties. As to any facts material to the opinions expressed herein which were not independently established or verified, we have relied upon oral or written statements and representations of officers, trustees and other representatives of the Company, the Trust and others. In rendering our opinion, we have participated in the preparation of the Prospectus Supplement. Our opinion is conditioned on, among other things, the initial and continuing accuracy of the facts, information, covenants, and representations set forth in the documents referred to above and the statements and representations made by the Company and the Trust. In rendering our opinion, we have considered the provisions of the Internal Revenue Code of 1986, as amended, Treasury regulations (proposed, temporary and final) promulgated thereunder, judicial decisions and Internal Revenue Service rulings all as of the date hereof, and all of which are subject to change, which changes may be retroactively applied. A change in the authorities

Occidental Petroleum Corporation Oxy Capital Trust I January 20, 1999 Page 4 upon which our opinion is based could affect our conclusions. There can be no assurance, moreover, that any opinion expressed herein will be accepted by the Internal Revenue Service or, if challenged, by a court. Based solely upon the foregoing, we are of the opinion that under current United States federal income tax law, although the discussion set forth in the Prospectus Supplement under the heading "CERTAIN UNITED STATES FEDERAL INCOME TAX CONSEQUENCES" does not purport to discuss all possible United States federal income tax consequences of the purchase, ownership, and disposition of the Preferred Securities, in our opinion such discussion constitutes, in all material respects, a fair and accurate summary of the United States federal income tax consequences, to holders who purchase the Preferred Securities at their original issuance, of the purchase, ownership, and disposition of the Preferred Securities. Except as set forth above, we express no opinion to any party as to the tax consequences, whether United States federal, state, local or foreign, of the issuance of the Subordinated Notes, the Preferred Securities, the Common Securities, or any transactions related to or contemplated by such issuance. We are furnishing this opinion to you solely for your benefit in connection with the sale of the Preferred Securities pursuant to the Underwriting Agreement and this opinion is not to be used, circulated, quoted, or otherwise referred to for any other purpose without our written permission. This opinion is expressed as of the date hereof, and we disclaim any undertaking to advise you of changes of the facts stated or assumed herein or any subsequent changes in applicable law. We consent to the filing of this opinion as Exhibit 8.1 to the Form 8-K of the Company dated January 13, 1999 as filed with the Securities and Exchange Commission on January 20, 1999, and to the reference to Skadden, Arps, Slate, Meagher & Flom LLP therein under the caption "Legal Matters."
