Ladies and Gentlemen:

Occidental Petroleum Corporation, a Delaware corporation (the "Company"), confirms its agreement with Banc of America Securities LLC ("Banc of America") and each of the underwriters named in Schedule A hereto (collectively, the "Underwriters," which term shall also include any underwriter substituted as hereinafter provided in Section 11 hereof), for whom Banc of America is acting as representative (in such capacity, the "Representative"), with respect to the sale by the Company and the purchase by the Underwriters of $300 million aggregate principal amount of the Company's 5.875% Senior Notes due January 15, 2007 (the "2007 Notes") and $500 million aggregate principal amount of the Company's 6.750% Senior Notes due January 15, 2012 (the "2012 Notes" and, together with the 2007 Notes, the "Notes"). The Notes are to be issued pursuant to an indenture (the "Indenture", which term, for the purpose of this Agreement, shall include the Officers' Certificate with respect to the Notes delivered pursuant to Sections 201 and 301 of the Indenture), dated as of April 1, 1998, between the Company and The Bank of New York, as trustee (the "Trustee").

The Company has filed with the Securities and Exchange Commission (the "Commission") a registration statement on Form S-3 (No. 333-79541) and, if applicable, one or more amendments thereto for the registration of, among other things, its senior debt securities, including the Notes, 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 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 Indenture has been qualified under the Trust Indenture Act of 1939, as amended (the "1939 Act"). Such registration statement (as amended, if applicable) and the prospectus constituting a part thereof, together with any prospectus supplement relating to the Notes (the "Prospectus Supplement"), including, in each case, all Incorporated Documents (as hereinafter defined), are referred to herein as the "Registration Statement" and the "Prospectus," respectively, except that, if any revised prospectus or revised prospectus supplement shall be provided to the Underwriters by the Company for use in connection with the offering of the Notes that is not required to be filed by the Company pursuant to Rule 424(b) of the 1933 Act Regulations, the term "Prospectus" shall refer to such revised prospectus or prospectus supplement, as the case may be, from and after the time it is first provided to the Underwriters for such use. Any registration statement filed pursuant to Rule 462(b) of the 1933 Act Regulations and relating to the Registration Statement 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. Any reference herein to the Registration Statement, any preliminary prospectus or the Prospectus shall be deemed to refer to and include the documents, financial statements and schedules incorporated or deemed to be incorporated by reference therein pursuant to Item 12 of Form S-3 under the 1933 Act, and any reference to any amendment or supplement to the Registration Statement or the Prospectus shall be deemed to refer to and include 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"). 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 Notes shall not be deemed to have supplemented the Prospectus.

For purposes of this Agreement, all references to the Registration Statement, any preliminary prospectus or the Prospectus 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").

The Company understands that the Underwriters propose to make a public offering of the Notes as soon as the Underwriters deem advisable after this Agreement has been executed and delivered.

SECTION 1 Representations and Warranties.

(a) The Company represents and warrants to the Underwriters as follows:

(i) 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 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 Notes, 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 Notes 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.

(ii) Each preliminary prospectus, if any, relating to the Notes 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 and at the Closing Time, the Registration Statement and the Prospectus, and any supplement or amendment thereto relating to the Notes, 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 Notes, 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 Notes 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.

(iii) This Agreement, the Indenture and the Notes (collectively, the "Transaction Documents") have been duly authorized by the Company. This Agreement and the Indenture have been duly executed and delivered by the Company, and the Transaction Documents conform in all material respects to the descriptions thereof in the Prospectus.

(iv) The Indenture (assuming the due execution and delivery thereof by the Trustee) is, and the Notes (when executed by the Company and authenticated in accordance with the Indenture and delivered to and paid for by the purchasers thereof) will be, the legal, valid and binding obligations of the Company, enforceable against the Company 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 Notes (when executed by the Company and authenticated in accordance with the terms of the Indenture and delivered to and paid for by the purchasers thereof) will be entitled to the benefits of the Indenture (subject to the exceptions set forth in the preceding sentence).

(v) The Company and each of Occidental Chemical Holding Corporation, a California corporation, and Occidental Oil and Gas Holding 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. The Company 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 the Company 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 the Company, 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 the Company.

(vi) 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 the Company 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.

(vii) The Company is not in violation of its Restated Certificate of Incorporation or Bylaws, in each case, as amended. The execution and delivery of this Agreement by the Company, the issuance and sale of the Notes and the performance by the Company of its obligations under this Agreement, the Indenture and the Notes 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 the Company, in each case, as amended, (B) any agreement or instrument (which is, individually or in the aggregate, material to the Company and its subsidiaries, taken as a whole) to which the Company is a party or by which it is bound or (C) any order of any court or governmental agency or authority presently in effect and applicable to the Company or any Principal Domestic Subsidiary. 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 Notes 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 Notes.

(viii) To the best of the Company'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.

(b) Additional Certifications. Any certificate signed by any officer of the Company 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 Company to the Underwriters as to the matters covered thereby on the date of such certificate.

Such counsel may state that "applicable laws" means the General Corporation Law of the State of Delaware and those laws, rules and regulations of the States of California and New York and the federal laws, rules and regulations of the United States of America, in each case, which, in such counsel's experience, are normally applicable to transactions of the type contemplated by this Agreement and the other Transaction Documents (other than the United States federal securities laws, state and foreign securities or blue sky laws, antifraud laws and the rules and regulations of the NASD), without his having made any special investigation as to the applicability of any other law, rule or regulation, and which are not the subject of a specific opinion herein referring expressly to a particular law or laws; "governmental authorities" means any court, regulatory body, administrative agency or governmental body of the States of California, Delaware or New York or the United States of America having

(vi) The Notes have been duly authorized by the Company and, when executed by the Company and authenticated by the Trustee in accordance with the terms of the Indenture (assuming the due authorization, execution and delivery of the Indenture by the Trustee) and issued to and paid for by the Underwriters in accordance with the terms of this Agreement, will be entitled to the benefits of the Indenture and will be valid and binding obligations of the Company enforceable against the Company in accordance with their respective terms, except (x) as may be subject to or limited by (A) bankruptcy, insolvency, reorganization, moratorium or other similar laws now or hereafter in effect relating to creditors' rights generally or (B) the effect of general principles of equity (regardless of whether such enforcement is sought in a proceeding in equity or at law) and (y) that the waiver contained in Section 515 of the Indenture may be deemed unenforceable.

(vii) 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.

(viii) The execution and delivery by the Company of each of the Transaction Documents and the consummation of the transactions contemplated thereby, including the issuance and sale of the Notes, 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 the Company, in each case, as amended, (B) any statute, law or regulation to which the Company 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 the Company 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 (viii) 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 Notes are to be offered.

(ix) The Registration Statement and the Rule 462(b) Registration Statement as of their respective effective dates, and the Prospectus, as supplemented by the Prospectus Supplement, as of the date of the Prospectus Supplement, 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 may state that, other than as set forth in clause (x) of this Section 6(b), such counsel assumes no responsibility for the accuracy, completeness or fairness of the statements contained in the Registration Statement or the Prospectus and 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 excluded therefrom or as to the Form T-1.

(x) The statements in the Prospectus under the captions "Description of Securities," "Description of Senior Debt Securities" and "Description of the Notes," insofar as they purport to summarize certain provisions of documents specifically referred to therein, fairly summarize such provisions in all material respects.

(xi) 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 the Company 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 the Company and its subsidiaries, taken as a whole.

(xii) 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.

(xiii) To the best of such counsel's knowledge, after reasonable inquiry, the Company is not in violation of its Restated Certificate of Incorporation or Bylaws, in each case, as amended.

(xiv) To the best of such counsel's knowledge, after reasonable inquiry, the execution and delivery of this Agreement and the Indenture by the Company, the issuance and sale of the Notes and the performance by the Company of its obligations under this Agreement, the Indenture and the Notes 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 the Company and its subsidiaries, taken as a whole, to which the Company is a party or by which it is bound.

In rendering such opinion such counsel may state that with respect to certain matters he has relied upon advice of other counsel employed by the Company 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 Company, outside counsel for the Company, representatives of the independent public accountants for the Company, 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 (x) 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 the Company 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 any 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.

(c) The Underwriter shall have received an opinion from Sidley Austin Brown & Wood LLP, counsel to the Underwriters, dated as of the Closing Time and in form and substance satisfactory to the Underwriters.

(d) Officer's Certificate. Except as contemplated in the Prospectus or reflected therein by the filing of any amendment or supplement thereto or any Incorporated Document, at the Closing Time, there shall not have been, since the date of the most recent consolidated financial statements included or incorporated by reference in the Prospectus, any material adverse change in the consolidated financial condition of the Company and its subsidiaries, taken as a whole. The Underwriters shall have received a certificate signed by an officer of the Company, dated as of the Closing Time, to the effect (i) that there has been no such material adverse change, (ii) that the representations and warranties of the Company contained in Section 1(a) hereof (other than Section 1(a)(vi)) are true and correct in all material respects with the same force and effect as though expressly made at and as of the date of such certificate, (iii) that the Company has complied with all agreements and satisfied all conditions required by this Agreement or the Indenture on its part to be performed or satisfied at or prior to the date of such certificate and (iv) that no stop order suspending the effectiveness of the Registration Statement has been issued and, to the best of such officer's knowledge, no proceedings for that purpose have been initiated or threatened by the Commission.

(e) Comfort Letter. At the Closing Time, the Underwriters shall have received a letter from the Company's independent public accountants, dated as of the Closing Time and in form and substance satisfactory to the Underwriters, containing statements and information of a type ordinarily included in accountants' "comfort letters" to underwriters with respect to the financial statements and certain financial information contained or incorporated by reference in the Registration Statement and the Prospectus; and, if financial statements for any assets, business or entity acquired by the Company are included or incorporated by reference in the Registration Statement or the Prospectus, the Underwriters shall have received a similar "comfort letter" from a firm of independent public accountants, dated as of the Closing Time and in form and substance satisfactory to the Representative, with respect to such financial statements and any financial information with respect to such assets, business or entity, as the case may be, contained or incorporated by reference in the Registration Statement and the Prospectus. Without limitation to the foregoing, the letter delivered by the Company's independent public accountants shall state that nothing has come to their attention that caused them to believe that at a specified date not more than five days prior to the date of such letter, there was any change in the outstanding capital stock of the Company or any increase in consolidated long-term debt of the Company or any decrease in the stockholders' equity of the Company, in each case as compared with the amounts shown on the most recent consolidated balance sheet of the Company incorporated by reference in the Registration Statement and Prospectus or, during the period from the date of such balance sheet to a specified date not more than five days prior to the date of such letter, there were any decreases, as compared with the corresponding period in the preceding year, in consolidated net sales and operating revenues or net income of the Company, except in each such case as set forth in or contemplated by the Registration Statement and Prospectus or except for such exceptions enumerated in such letter as shall have been agreed to by the Representative and the Company.

(f) Other Documents. At the Closing Time, counsel for the Underwriters shall have been furnished with resolutions of the Company's Board of Directors authorizing and approving the issuance and sale of the Notes and matters related thereto and such other documents and opinions as they may reasonably require for the purpose of enabling them to pass upon the issuance and sale of the Notes as herein contemplated and related proceedings, or in order to evidence the accuracy of any of the representations or warranties, or the fulfillment of any of the conditions, herein contained.

If any condition specified in this Section 6 shall not have been fulfilled when and as required to be fulfilled, this Agreement may be terminated by the Representative by notice to the Company at any time at or prior to the Closing Time, and any such termination shall be without liability of any party to any other party, except as provided in Section 5, and except that the indemnity and contribution agreements set forth in Sections 7 and 8 hereof and the provisions of Section 9 hereof shall remain in effect.

SECTION 7 Indemnification.

(a) Indemnification of the Underwriters. The Company agrees to indemnify and hold harmless each Underwriter and each person, if any, who controls an Underwriter within the meaning of Section 15 of the 1933 Act as follows:

(i) 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, insofar as such loss, liability, claim, damage or expense arises out of any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading, or arises out of any untrue statement or alleged untrue statement of a material fact contained in the Prospectus or the omission or alleged 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 the Company; 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 Company 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 Note or Notes to the person asserting such loss, liability, claim, damage or expense who purchased such Note or Notes that are the subject thereof from such Underwriter; or (C) as to which such Underwriter may be required to indemnify the Company pursuant to the provisions of subsection (b) of this Section 7; or (D) if such loss, liability, claim, damage or expense is covered by any other written agreement between the Company and such Underwriter pertaining to the sale of the Notes pursuant to which such Underwriter may be required to indemnify the Company for such loss, liability, claim, damage or expense.

(b) Indemnification of the Company. Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, its directors, each of its officers who signed the Registration Statement, and each person, if any, who controls the Company 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 Company by or on behalf of any such Underwriter expressly for use in the Registration Statement or the Prospectus.

(i) 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 Company pursuant to this Section 7, such Underwriter or controlling person shall promptly notify the Company in writing, and the Company 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 the Company, (B) the Company 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 Company, 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 Company (in which case, if such Underwriter or such controlling person notifies the Company in writing that it elects to employ separate counsel at the expense of the Company, the Company 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 the Company 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 Representative, on behalf of all such Underwriters and all such controlling persons).

(ii) In case any action, suit or proceeding (including any governmental or regulatory investigation or proceeding) shall be brought against the Company, any of the Company's directors or officers, or any person controlling the Company, 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 the Company by subsection (c)(i) of this Section 7, and the Company, the Company's directors and officers and any such controlling person shall have the rights and duties given to the Underwriters by subsection (c)(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, the Company and each Underwriter shall contribute to the aggregate losses, liabilities, claims, damages and expenses of the nature contemplated by said indemnity agreement incurred by the Company and the Underwriters, as incurred, (i) in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and each of the Underwriters, on the other hand, from the offering of the Notes 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 Company, 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 the Company, 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 Notes (before deducting expenses) received by the Company as set forth on the cover page of the Prospectus, 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 Notes as set forth on the cover page of the Prospectus. The relative fault of the Company, 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 the Company 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 Notes 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 Notes 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 the Company, each officer of the Company who signed the Registration Statement and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act shall have the same rights to contribution as the Company. 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 contained in certificates of officers of the Company 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 any

controlling person of any Underwriter, or by or on behalf of the Company, and shall survive each delivery of and payment for any of the Notes.

SECTION 10 Termination.

(a) The Representative may terminate this Agreement, by notice to the Company, 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 Company 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 Representative, impracticable to market or to enforce contracts for sale of the Notes or other debt securities, (iii) trading in any securities of the Company 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 Notes or the Company's long-term debt generally on what is commonly termed a "watch list" for possible downgrading or (B) downgraded the Notes or the Company's long-term debt generally, or (v) the Company 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.

SECTION 11 Default By One or More of the Underwriters.

If one or more of the Underwriters shall fail at Closing Time to purchase the Notes which it or they are obligated to purchase under this Agreement (the "Defaulted Notes"), the non-defaulting Underwriters shall have the right, within 24 hours thereafter, to make arrangements for one or more of such non-defaulting Underwriters, or any other underwriters, to purchase all, but not less than all, of the Defaulted Notes in such amounts as may be agreed upon and upon the terms herein set forth: if, however, such non-defaulting Underwriters shall not have completed such arrangements within such 24-hour period, then:

(a) if the aggregate principal amount of Defaulted Notes does not exceed 10% of the aggregate principal amount of the Notes, the non-defaulting Underwriters shall be obligated 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 aggregate principal amount of Defaulted Notes exceeds 10% of the aggregate principal amount of the Notes, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter.

No action 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, either the non-defaulting Underwriters or the Company shall have the right to postpone the Closing Time 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.

SECTION 12 Notices.

All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed or transmitted by any standard form of telecommunication. Notices to the Underwriters shall be directed to them c/o Banc of America Securities LLC, Bank of America Corporate Center, 100 North Tryon Street, Charlotte, North Carolina 28255, attention: Transaction Services. Notices to the Company shall be directed to it 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 Company 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 parties hereto and their respective successors and the controlling persons and officers and directors referred to in Sections 7 and 8 hereof and their heirs and legal representatives, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provisions herein contained. This Agreement and all conditions and provisions hereof are intended to be for the sole and exclusive benefit of the parties hereto and their respective successors and said controlling persons and officers and directors and their heirs and legal representatives, and for the benefit of no other person, firm or corporation. No purchaser of Notes shall be deemed to be a successor by reason merely of such purchase.

SECTION 14 Governing Law.

This Agreement and the rights and obligations of the parties created hereby shall be governed by and construed in accordance with the laws of the State of New York applicable to agreements made and to be performed in such State, including, without limitation, Section 5-1401 of the New York General Obligations Law.

If the foregoing is in accordance with your understanding of our agreement, please sign and return to the Company a counterpart hereof, whereupon this instrument along with all counterparts will become a binding agreement between the Underwriters and the Company in accordance with its terms.

Very truly yours,
