Dear Sirs:

Anadarko Petroleum Corporation, a Delaware corporation (the “Company”), proposes to issue and sell its debt securities (the “Securities”) in one or more offerings on terms determined at the time of sale. The Securities will be issued in one or more series under an indenture specified in the applicable Terms Agreement (the “Indenture”). Each series of Securities to be issued may vary as to aggregate principal amount, currency, maturity, interest rate or rates and timing of payments thereof, redemption provisions, sinking fund requirements, conversion provisions, if any, and any other variable terms which the Indenture contemplates may be set forth in the Securities as issued from time to time.

The provisions included herein (the “Standard Provisions”) shall be incorporated by reference into each Terms Agreement. The term “you” or “your” as used herein, unless the context otherwise requires, shall mean such of the parties to whom these Standard Provisions are addressed as are named in the applicable Terms Agreement.

Each offering of Securities will be made through one or more of you or through an underwriting syndicate managed by one or more of you.

The representative or representatives of the Underwriters, if any, specified in a Terms Agreement are hereinafter referred to as the “Representatives.” The Terms Agreement relating to each offering of Securities shall specify the principal amount of each series of the Securities to be issued, whether such Securities are senior or subordinated debt securities, and their terms not otherwise specified in the Indenture, the names of the Underwriters participating in such offering (subject to substitution as provided in Section 9 hereof) and the principal amount of each series of the Securities which each Underwriter severally agrees to purchase (collectively, the “Firm Securities”), the names of such of you and such other Underwriters, if any, acting as co-managers in connection with such offering, the price at which each series of the Securities are to be purchased by the Underwriters from the Company, the initial public offering price of each such series and the time and place of delivery and payment. In addition, the Terms Agreement shall specify the maximum principal amount of each series of the Securities, if any (the “Additional Securities”), that the Company proposes to issue and sell to the Underwriters if and to the extent

that you shall have determined to exercise, on behalf of the several Underwriters, the right to purchase such Additional Securities. The Terms Agreement may take the form of an exchange of any standard form of written telecommunication between you and the Company. Each offering of Securities will be governed by these Standard Provisions, as supplemented by the applicable Terms Agreement, and these Standard Provisions and such Terms Agreement shall inure to the benefit of and be binding upon each Underwriter participating in the offering of such Securities.

Section 1. Representations and Warranties. The Company represents and warrants to each of you, and to each Underwriter named in a Terms Agreement as of the date thereof as follows:

(a) The Company has filed with the Commission a registration statement on Form S-3 (No. 333-192219), including a related prospectus or prospectuses, covering the registration of the Securities under the Act, which has become effective.

(b) The Registration Statement constitutes an “automatic shelf registration statement” (as defined in Rule 405 of the Act) filed within three years of the date of the applicable Terms Agreement, and the Company is a “well-known seasoned issuer” (as defined in Rule 405 of the Act). No order suspending the effectiveness of the Registration Statement has been issued by the Commission and no proceeding for that purpose or pursuant to Section 8A of the Act against the Company or related to the offering has been initiated or threatened by the Commission. The Company has not received from the Commission any notice pursuant to Rule 401(g)(2) objecting to use of the automatic shelf registration statement form. If at any time when any Securities remain unsold by the Underwriters the Company receives from the Commission a notice pursuant to Rule 401(g)(2) or otherwise ceases to be eligible to use the automatic shelf registration statement form, the Company will (i) promptly notify the Representatives, (ii) promptly file a new registration statement or post-effective amendment on the proper form relating to the Securities, in a form reasonably satisfactory to the Representatives, (iii) use its reasonable best efforts to cause such registration statement or post-effective amendment to be declared effective as soon as practicable, and (iv) promptly notify the Representatives of such effectiveness. The Company will take all other action reasonably necessary or appropriate to permit the public offering and sale of the Securities to continue as contemplated in the registration statement that was the subject of the Rule 401(g)(2) notice or for which the Company has otherwise become ineligible. References herein to the Registration Statement shall include such new registration statement or post-effective amendment, as the case may be. The Company has paid or shall pay the required Commission filing fees relating to the Securities within the time required by Rule 456(b)(1) without regard to the proviso therein and otherwise in accordance with Rules 456(b) and 457(r).

(c) (i) At the time of filing the Registration Statement and (ii) at the date of the Terms Agreement, the Company was not and is not an “ineligible issuer,” as defined in Rule 405.

(d) (i) (A) At the time the Registration Statement initially became effective, (B) at the time of each amendment thereto for the purposes of complying with Section 10(a)(3) of the Act (whether by post-effective amendment, incorporated report or form of prospectus), (C) on the Effective Date relating to the Securities and (D) on the Closing Date, the Registration Statement conformed and will conform in all material respects to the requirements of the Act, the Trust Indenture Act and the Rules and Regulations and did not and will not include any

untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading and (ii) (A) on its date, (B) at the time of filing the Prospectus pursuant to Rule 424(b) and (C) on the Closing Date, the Prospectus will conform in all material respects to the requirements of the Act, the Trust Indenture Act and the Rules and Regulations, and will not include any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. The preceding sentence does not apply to (i) statements in or omissions from any such document made in reliance upon and in conformity with written information furnished to the Company by any Underwriter through the Representatives, if any, specifically for use therein, it being understood and agreed that the only such information is that described as such in the Terms Agreement or (ii) that part of the Registration Statement that will constitute the Statement of Eligibility and Qualification under the Trust Indenture Act (Form T-1) of the Trustee under the Indenture (the “Form T-1”).

(e) As of the Applicable Time, neither (i) the General Use Issuer Free Writing Prospectus(es) issued at or prior to the Applicable Time, the Statutory Prospectus identified in a schedule to the Terms Agreement, and any other documents listed or disclosures stated in a schedule to the Terms Agreement to be included in the Disclosure Package, all considered together (collectively, the “Disclosure Package”), nor (ii) any electronic road show or other written communications reviewed and consented to by the Representatives and listed on Schedule II hereto (each a, “Company Additional Written Communication”) or any individual Limited Use Issuer Free Writing Prospectus, when considered together with the Disclosure Package, included any untrue statement of a material fact or omitted to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. The preceding sentences do not apply to statements in or omissions from any Statutory Prospectus, any Issuer Free Writing Prospectus or any Company Additional Written Communication in reliance upon and in conformity with written information furnished to the Company by any Underwriter through the Representatives specifically for use therein, it being understood and agreed that the only such information is that described as such in the Terms Agreement.

(f) Each Issuer Free Writing Prospectus, as of its issue date and at all subsequent times through the completion of the public offer and sale of the Securities or until any earlier date that the Company notified or notifies the Representatives as described in the next sentence, did not, does not and will not include any information that conflicted, conflicts or will conflict with the information then contained in the Registration Statement. If at any time following issuance of an Issuer Free Writing Prospectus there occurred or occurs an event or development as a result of which such Issuer Free Writing Prospectus conflicted or would conflict with the information then contained in the Registration Statement or as a result of which such Issuer Free Writing Prospectus, if republished immediately following such event or development, would include an untrue statement of a material fact or omitted or would omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances prevailing at that subsequent time, not misleading, (i) the Company has promptly notified or will promptly notify the Representatives and (ii) the Company has promptly amended or will promptly amend or supplement such Issuer Free Writing Prospectus to eliminate or correct such conflict, untrue statement or omission.

If applicable, the pro forma financial information set forth or incorporated by reference in the Registration Statement, the Prospectus and the Disclosure Package is, in all material respects, fairly presented and prepared on a basis consistent with the historical financial statements of the Company and its subsidiaries, except to the extent stated therein, and gives effect to assumptions used in the preparation thereof which have been made on a reasonable basis and in good faith.

(i) The Company has established and maintains disclosure controls and procedures (as such term is defined in Rule 13a-15 under the Exchange Act); such disclosure controls and procedures are designed to ensure that material information relating to the Company and its subsidiaries is made known to the chief executive officer and chief financial officer of the Company by others within the Company or any subsidiary, and such disclosure controls and procedures are reasonably effective to perform the functions for which they were established subject to the limitations of any such control system.

Each Significant Subsidiary is duly qualified or licensed to do business as a foreign corporation, partnership or limited liability company in good standing in each jurisdiction in which the conduct of its business or its ownership or leasing of property requires such qualification or licensing, except to the extent that the failure to be so qualified or licensed or be in good standing would not have a Material Adverse Effect. The issued and outstanding common stock or other equity interests of each of the Significant Subsidiaries have been duly authorized and validly issued and are fully paid and non-assessable and, except as disclosed in the Prospectus and the Disclosure Package, are owned by the Company free and clear of any mortgages, liens or similar encumbrances.

Section 2. Purchase and Sale. The several commitments of the Underwriters to purchase, and the obligation of the Company to sell, Securities pursuant to any Terms Agreement shall be deemed to have been made on the basis of the representations and warranties herein contained and shall be subject to the terms and conditions herein set forth.

Payment of the purchase price for, and delivery of, any Firm Securities to be purchased by the Underwriters shall be made at such time and place and on such date as specified in the applicable Terms Agreement (unless postponed in accordance with the provisions of Section 9 hereof) (each such time and date being referred to herein as a “Closing Date”). Payment shall be made to the Company in Federal or other funds immediately available in New York City or by such other means as may be specified in the Terms Agreement against delivery to you for the respective accounts of the Underwriters of the Firm Securities to be purchased by them.

If so specified in the applicable Terms Agreement, the Underwriters shall have a one-time right to purchase, severally and not jointly, up to the principal amount of Additional Securities set forth in the applicable Terms Agreement at the purchase price set forth in the applicable Terms Agreement plus accrued interest, if any. Additional Securities may be purchased solely for the purpose of covering over-allotments made in connection with the offering of the Firm Securities. If any Additional Securities are to be purchased, each Underwriter agrees, severally and not jointly, to purchase the principal amount of Additional Securities (subject to such adjustments to eliminate fractions of $1,000 as you may determine) that bears the same proportion to the total principal amount of Additional Securities to be purchased as the principal amount of Firm Securities set forth opposite its name in the applicable Terms Agreement bears to the total principal amount of Firm Securities.

Payment of the purchase price for, and delivery of, any Additional Securities to be purchased by the Underwriters shall be made at such time (which may be the same as the Closing Date but shall in no event be earlier than the Closing Date nor later than ten business days after the giving of the notice hereinafter referred to) and place as shall be designated in a written notice from you to the Company of your determination, on behalf of the Underwriters, to purchase the principal amount, specified in such notice, of Additional Securities, or at such other time, in any event not later than 30 days after the Closing Date, as shall be designated in writing by the Underwriters. The time and date of such payment are hereinafter referred to as the “Option Closing Date.” The notice of the determination to exercise the option to purchase Additional Securities and of the Option Closing Date may be given at any time within 30 days after the date of the Terms Agreement.

Certificates evidencing the Firm Securities and Additional Securities shall be in definitive, global form and registered in the name of Cede & Co., as nominee for The Depository Trust Company, unless you shall request otherwise in writing not less than two full business days prior to the Closing Date or the Option Closing Date, as the case may be. The certificates evidencing the Firm Securities and Additional Securities shall be delivered to you at the Closing Date or the Option Closing Date, as the case may be, for the respective accounts of the several Underwriters, with any transfer taxes payable in connection with the transfer of the Securities to the Underwriters duly paid, against payment of the purchase price therefor.

Section 3. Covenants of the Company. The Company covenants with each of you, and with each Underwriter participating in the applicable offering of Securities, as follows with respect to such offering of Securities:

(a) As soon as practicable, following the execution of the applicable Terms Agreement, the Company will prepare the Prospectus setting forth the principal amount of each series of the Securities covered thereby and their terms not otherwise specified in the Indenture, the names of the Underwriters participating in the offering and the principal amount of each series of the Securities which each severally has agreed to purchase, the names of the Underwriters acting as co-managers in connection with the offering, the price at which each series of the Securities is to be purchased by the Underwriters from the Company, the initial public offering price of each such series, if applicable, the selling concession and reallowance applicable to each such series, if any, any Additional Securities information and such other information as you and the Company deem appropriate in connection with the offering of the Securities. The Company will transmit copies of the Prospectus to the Commission in compliance with Rule 424 under the Act and will furnish to the Underwriters named therein as many copies of the Prospectus and the Disclosure Package as you shall reasonably request for the purposes contemplated by the Act or the Rules and Regulations.

(b) If at any time when the Prospectus (or in lieu thereof the notice referred to in Rule 173(a) under the Act) is required by the Act to be delivered in connection with sales of such Securities any event shall occur or condition exist as a result of which it is necessary to further amend or supplement the Prospectus in order that the Prospectus will not include an untrue statement of a material fact or omit to state any material fact necessary to make the statements therein not misleading in the light of circumstances existing at the time it is delivered to a purchaser or if it shall be necessary at any time to amend or supplement the Registration Statement or the Prospectus in order to comply with the requirements of the Act or the Rules and Regulations, the Company will, as soon as practicable, prepare and file (if required) with the Commission such amendment or supplement, whether by filing documents pursuant to the Exchange Act or otherwise, as may be necessary to correct such untrue statement or omission or to make the Registration Statement comply with such requirements.

(c) If the Disclosure Package is being used to solicit offers to buy the Securities at a time when the Prospectus is not yet available to prospective purchasers and any event shall occur or condition exist as a result of which it is necessary to amend or supplement the Disclosure Package in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if any event shall occur or condition exist as a result of which the Disclosure Package conflicts with the information contained in the Registration Statement then on file, or if, in the opinion of counsel for the Underwriters, it is necessary to amend or supplement the Disclosure Package to comply with applicable law, the Company will prepare, file with the Commission and furnish, at its own expense, to the Underwriters and to any dealer upon request, either amendments or supplements to the Disclosure Package so that the statements in the Disclosure Package as so amended or supplemented will not contain any statement of untrue material fact or omit to state a material fact necessary in order to make the statements not misleading, in the light of the circumstances when delivered to a prospective purchaser, or so that the Disclosure Package, as amended or supplemented, will no longer conflict with the Registration Statement, or so that the Disclosure Package, as amended or supplemented, will comply with applicable law.

(d) The Company will make generally available to its security holders as soon as practicable, but in any event not later than 18 months after the date of the Terms Agreement relating to such Securities, earnings statements of the Company and its subsidiaries (which need not be audited) complying with Section 11(a) of the Act and the Rules and Regulations (including, at the option of the Company, Rule 158 under the Act).

(e) The Company, during the period when the Prospectus (or in lieu thereof, the notice referred to in Rule 173(a) under the Act) is required by the Act to be delivered in connection with sales of such Securities, will give you notice of its intention to file any amendment to the Registration Statement or any amendment or supplement to the Prospectus or the Disclosure Package, whether pursuant to the Act or otherwise and will furnish you with copies of any such amendment or supplement or other documents proposed to be filed in a reasonable time for review by the Underwriters in advance of filing.

(f) The Company, during the period when the Prospectus (or in lieu thereof, the notice referred to in Rule 173(a) under the Act) is required by the Act to be delivered by you in connection with sales of Securities, will notify each of you, as soon as practicable, and confirm the notice in writing, of: (i) the effectiveness of any amendment to the Registration Statement; (ii) the mailing or delivery to the Commission for filing of any supplement to the Prospectus or the Disclosure Package, or any document to be filed pursuant to the Exchange Act; (iii) the receipt of any comments from the Commission with respect to the Registration Statement, the Prospectus or the Disclosure Package; (iv) any request by the Commission for any amendment to the Registration Statement or any amendment or supplement to the Prospectus or the Disclosure Package or for additional information; (v) the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or of the threat or initiation of any proceedings for that purpose or pursuant to Section 8A of the Act; and (vi) the receipt by the Company of any notice of objection of the Commission to the use of the Registration Statement or any post-effective amendment thereto pursuant to Rule 401(g)(2) under the Act. The Company will make every reasonable effort to prevent the issuance of any such stop order and, if any such stop order is issued, to obtain the lifting thereof at the earliest possible moment.

(g) The Company will deliver to each of you, as soon as practicable, as many conformed copies of the Registration Statement (as originally filed) and of each amendment thereto (including, except to the extent available on XXXXX, exhibits filed therewith or incorporated by reference therein and documents incorporated by reference in the Prospectus and the Disclosure Package pursuant to Item 12 of Form S-3 under the Act) as you may reasonably request and will also deliver to you, upon your request, a conformed copy of the Registration Statement and each amendment thereto for each of the Underwriters.

(h) The Company will cooperate with you to qualify the Securities for offering and sale under the applicable Blue Sky or securities laws of such states and other jurisdictions of the United States as you may designate, and will cooperate in maintaining such qualifications in effect for as long as may be required for the distribution of such Securities except that the Company shall not be obligated to file any general consent to service or to qualify as a foreign corporation or as a dealer in securities in any jurisdiction in which it is not so qualified. In each jurisdiction in which such Securities or the sale thereof shall have been qualified as above provided, the Company will cooperate with you to make and file such statements and reports in each year as may be required by the laws of such jurisdiction. The Company will cooperate in the determination of the eligibility for investment of the Securities under the laws of such jurisdictions as you reasonably request.

(i) If so specified in the applicable Terms Agreement, the Company will not, without your prior written consent, offer, sell, contract to sell or otherwise dispose of any securities of the Company designated in such Terms Agreement during the lock-up period specified in the applicable Terms Agreement, other than: (i) the Securities to be sold hereunder; (ii) the Common Stock, if any, issuable upon conversion of the Securities or conversion of any other existing securities convertible into Common Stock or upon exercise of any existing options to purchase Common Stock; (iii) options or shares of Common Stock sold or issued pursuant to any employee benefit plan or arrangement of the Company or any of its subsidiaries existing on the date of the applicable Terms Agreement; and (iv) Common Stock issuable in connection with any acquisition.

Section 4. Free Writing Prospectuses.

(a) Issuer Free Writing Prospectuses. The Company represents and agrees that, unless it obtains the prior consent of the Representatives, and each Underwriter represents and agrees, severally and not jointly, that, unless it obtains the prior consent of the Company and the Representatives, it has not made and will not make any offer relating to the Securities that would constitute an Issuer Free Writing Prospectus, or that would otherwise constitute a “free writing prospectus,” as defined in Rule 405, required to be filed with the Commission. Any such free writing prospectus consented to by the Company and the Representatives is hereinafter referred to as a “Permitted Free Writing Prospectus.” The Company represents that it has treated and agrees that it will treat each Permitted Free Writing Prospectus as an “issuer free writing prospectus,” as defined in Rule 433, and has complied and will comply with the requirements of Rules 164 and 433 applicable to any Permitted Free Writing Prospectus, including timely Commission filing where required, legending and record keeping. The Company represents that it has satisfied and agrees that it will satisfy the conditions under Rule 433 under the Act to avoid a requirement to file with the Commission any Company Additional Written Communication made in connection with the offering of the Securities.

(b) Term Sheets. If so indicated in the Terms Agreement, the Company will prepare a final term sheet relating to the Securities, containing only information that describes the final terms of the Securities and otherwise in a form consented to by the Underwriters, and will file such final term sheet within the period required by Rule 433(d)(5)(ii) following the date such final terms have been established for all classes of the offering of the Securities. Any such final term sheet is an Issuer Free Writing Prospectus and a Permitted Free Writing Prospectus for purposes of the Terms Agreement. The Company also consents to the use by any Underwriter of a free writing prospectus that contains only (i)(x) information describing the preliminary terms of the Securities or their offering or (y) information that describes the final terms of the Securities or their offering and that is included in the final term sheet of the Company contemplated in the first sentence of this subsection or (ii) other information that is not “issuer information,” as defined in Rule 433, it being understood that any such free writing prospectus referred to in clauses (i) or (ii) above shall not be an Issuer Free Writing Prospectus for purposes of these Standard Provisions.

Section 5. Conditions of Your Obligations. The obligations of the Underwriters to purchase Securities pursuant to any Terms Agreement are subject to the accuracy in all material respects, unless otherwise qualified by materiality (in which case such representations and warranties will be accurate), of the representations and warranties on the part of the Company herein contained as of the date of the Terms Agreement and as of the applicable Closing Date, to the performance by the Company in all material respects of all of its covenants and other obligations hereunder and to the following further conditions:

(a) The Prospectus and the final term sheet free writing prospectus shall have been filed with the Commission in accordance with the Rules and Regulations and Section 3(a) and Section 4(b) hereof.

(iv) The Registration Statement has become effective under the Act and, to such counsel’s knowledge, no stop order suspending the effectiveness of the Registration Statement has been issued under the Act, and no proceeding pursuant to Section 8A of the Act against the Company or in connection with the offering is pending or, to the knowledge of such counsel, threatened by the Commission.

obligations hereunder and under the Indenture in relation to the Securities do not and will not result in a violation of the Company’s certificate of incorporation or bylaws or the laws of the State of New York, other than state securities laws or “Blue Sky” laws, as to which such counsel need express no opinion.

(ix) The Company is not, and immediately after giving effect to the offering and sale of the Securities and the application of the proceeds thereof as described in the Prospectus will not be, required to register as an “investment company,” as such term is defined in the Investment Company Act of 1940, as amended.

(x) The statements in the Prospectus under the captions “Description of the notes” and “Description of Debt Securities,” insofar as such statements constitute a summary of the terms of the Securities and the Indenture, fairly summarize the terms of the Securities and the Indenture in all material respects.

(xi) The statements included in the Disclosure Package and the Prospectus under the heading “Certain U.S. federal income tax considerations,” insofar as such statements summarize legal matters, agreements, documents or proceedings discussed therein, are accurate and fair summaries of such legal matters, agreements, documents or proceedings in all material respects.

Such special counsel shall also state that:

(A) Each of the Registration Statement, the documents incorporated by reference therein, the Prospectus and any supplements or amendments thereto (except the financial statements, financial schedules and other financial, accounting, reserve and production data contained or incorporated by reference therein and except for that part of the Registration Statement that contains the Form T-1 as to which such counsel need express no view), at the time it was filed with the Commission, appeared on its face to be appropriately responsive in all material respects to the requirements of the Act and the Exchange Act and the rules and regulations thereunder; and

(B) No information has come to such counsel’s attention that causes such special counsel to believe that (i) the Registration Statement, as of its effective date and as of the date of the Terms Agreement, 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; (ii) the Disclosure Package, as of the Applicable Time, contained any untrue statement of a material fact or omitted to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading or (iii) the Prospectus, as amended or supplemented, if applicable, as of its date and as of the Closing Date, contained or contains any untrue statement of a material fact or omitted or omits to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, except that in the case of each of clauses (i)-(iii) above, such counsel need not express any view as to the financial statements, financial schedules and other financial, accounting, reserve and production data contained or incorporated by reference therein and except for that part of the Registration Statement that contains the Form T-1.

With respect to subparagraphs (A) and (B) above, such counsel may state that their opinion and belief are based upon their participation in the preparation of the Registration Statement, the Prospectus and the Disclosure Package, and any amendments or supplements thereto, and review and discussion of the contents thereof, but are without independent check or verification except as specified and without assumption of any responsibility for the accuracy, completeness or fairness of the statements contained or incorporated therein except as otherwise provided in clauses (iii), (v), (x) and (xi) above.

In rendering such opinion, such special counsel may opine only as to the Federal laws of the United States, the laws of the States of New York and Texas and the General Corporation Law of the State of Delaware.

(c) Actions against Parties; Notification. Promptly after receipt by an indemnified party under this Section of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under subsection (a) or (b) above, notify the indemnifying party in writing of the commencement thereof; but the failure to notify the indemnifying party shall not relieve it from any liability that it may have under subsection (a) or (b) above except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided further that the failure to notify the indemnifying party shall not relieve it from any liability that it may have to an indemnified party otherwise than under subsection (a) or (b) above. In case any such action is brought against any indemnified party and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party under this Section for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof, provided that the indemnifying party shall reimburse any legal or other expenses incurred by such indemnified party for separate counsel (including a local counsel) if (i) the indemnified party shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the indemnifying party or (ii) the named parties in any such action (including any impleaded parties) include both the indemnifying party and the indemnified party and the indemnified party reasonably determines that representation of both parties by the same counsel would be inappropriate due to the actual or potential differing interest between them. It is understood and agreed that the indemnifying party shall not, in connection with any action or related action in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all indemnified parties. The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent (which consent shall not be unreasonably withheld), but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time the indemnified party shall have requested in writing that the indemnifying party reimburse the indemnified party for fees and expenses of counsel as contemplated by this Section 7, the indemnifying party shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by the indemnifying party of such request and (ii) the indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened action in respect of which any

indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party unless such settlement (i) includes an unconditional release of such indemnified party from all liability on any claims that are the subject matter of such action and (ii) does not include a statement as to, or an admission of, fault, culpability or a failure to act by or on behalf of an indemnified party. In no event shall the indemnifying party be liable for the fees and expenses of more than one counsel (in addition to appropriate local counsel) at any time for any indemnified party in connection with any one action or separate but substantially similar or related actions arising in the same jurisdiction out of the same general allegations or circumstances.

(d) Contribution. If the indemnification provided for in this Section is unavailable or insufficient to hold harmless an indemnified party under subsection (a) or (b) above, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities referred to in subsection (a) or (b) above (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other 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 Company on the one hand and the Underwriters on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by the Underwriters from the Company hereunder. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any action or claim which is the subject of this subsection (d). Notwithstanding the provisions of this subsection (d), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations in this subsection (d) to contribute are several in proportion to their respective underwriting obligations and not joint. The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7(d) were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to in this Section 7(d).

(e) Control Persons. The obligations of the Company under this Section shall be in addition to any liability which the Company may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls any Underwriter within the meaning of the Act; and the obligations of the Underwriters under this Section shall be in addition to any liability which the respective Underwriters may otherwise have and shall extend, upon the same terms and conditions, to each director of the Company, to each officer of the Company who has signed the Registration Statement and to each person, if any, who controls the Company within the meaning of the Act.

Section 8. Survival of Certain Representations and Obligations. The respective indemnities, agreements, representations, warranties and other statements of the Company or its officers and of the several Underwriters set forth in or made pursuant to the Terms Agreement (including these Standard Provisions) will remain in full force and effect, regardless of any investigation, or statement as to the results thereof, made by or on behalf of any Underwriter, the Company or any of their respective representatives, officers or directors or any controlling person, and will survive delivery of and payment for the Securities. If the purchase of the Securities by the Underwriters is not consummated for any reason other than because of the termination of the Terms Agreement pursuant to Sections 5(c)(iii), (iv), (vi), (vii) and (viii) or Section 9 hereof, the Company will reimburse the Underwriters for all out-of-pocket expenses (including fees and disbursements of counsel) reasonably incurred by them in connection with the

offering of the Securities, and the respective obligations of the Company and the Underwriters pursuant to Section 7 hereof shall remain in effect. In addition, if any Securities have been purchased under the Terms Agreement, the representations and warranties in Section 1 hereof and all obligations under Section 3 hereof shall also remain in effect.

Section 9. Default. If one or more of the Underwriters participating in an offering of Securities shall fail at the applicable Closing Date or Option Closing Date, as the case may be, to purchase the Securities which it or they are obligated to purchase at such time under the applicable Terms Agreement (the “Defaulted Securities”), then such of you as are named therein shall have the right, within 36 hours thereafter, to make arrangements for one or 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, during such 36 hours you shall not have completed such arrangements for the purchase of all of the Defaulted Securities, and if the Company shall not have completed arrangements for the purchase of all, but not less than all, of the Defaulted Securities by other underwriters satisfactory to such of you as are named in the applicable Terms Agreement, then:

(a) if the aggregate principal amount of Defaulted Securities does not exceed 10% of the aggregate principal amount of Firm Securities to be purchased pursuant to such Terms Agreement, the non-defaulting Underwriters shall be obligated to purchase the full amount thereof in the proportions that their respective underwriting obligations under the applicable Terms Agreement bear to the aggregate principal amount of Firm Securities set forth opposite the names of all such non-defaulting Underwriters; or

(b) if the aggregate principal amount of Defaulted Securities exceeds 10% of the aggregate principal amount of Firm Securities to be purchased pursuant to such Terms Agreement, the applicable Terms Agreement shall terminate, without any liability on the part of any non-defaulting Underwriter or the Company except, in each case, as provided in Sections 7 and 8 hereof.

No action taken pursuant to this Section shall relieve any defaulting Underwriter from liability to the Company or any non-defaulting Underwriter for damages in respect of any default of such Underwriter hereunder and the applicable Terms Agreement.

In the event of a default by any Underwriter or Underwriters as set forth in this Section which does not result in a termination of the applicable Terms Agreement, either you or the Company shall have the right to postpone the applicable Closing Date or Option Closing Date, as the case may be, for a period not exceeding seven days in order that any required changes in the Registration Statement or Prospectus or in any other documents or arrangements may be effected.

Section 10. 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 you, at the address indicated in the applicable Terms Agreement; and notices to the Company shall be directed to it at: 0000 Xxxx Xxxxxxx Xxxxx, Xxx Xxxxxxxxx, Xxxxx 00000-0000, attention of Vice President and Treasurer, or to such other address or person as may be designated in any such notice.

Section 11. Parties. These Standard Provisions shall inure to the benefit of and be binding upon you and the Company, and any Terms Agreement shall inure to the benefit of and be binding upon the Company and any Underwriter who becomes a party to a Terms Agreement, and their respective successors. Nothing expressed or mentioned herein or any Terms Agreement is intended or shall be construed to give any person, firm or corporation, other than the parties hereto or thereto and their respective successors and the controlling persons and officers and directors referred to in Section 7 hereof and their heirs and legal representatives, any legal or equitable right, remedy or claim under or in respect of these Standard Provisions or a Terms Agreement or any provision herein or therein contained. These Standard Provisions and any Terms Agreement and all conditions and provisions hereof and thereof are intended to be for the sole and exclusive benefit of the parties and their respective successors and such 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 any Securities from any Underwriter shall be deemed to be a successor by reason merely of such purchase.

Section 12. GOVERNING LAW. THESE STANDARD PROVISIONS AND EACH TERMS AGREEMENT, AND ANY CLAIM, CONTROVERSY OR DISPUTE ARISING UNDER OR RELATED TO THESE STANDARD PROVISIONS AND EACH TERMS AGREEMENT, SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

Section 13. Counterparts. The applicable Terms Agreement may be signed by the parties in counterparts which together shall constitute one and the same agreement among the parties and shall become effective at such time as each of the parties shall have signed such counterparts and shall have notified the other parties thereof.

Section 14. Absence of Fiduciary Relationship. The Company acknowledges and agrees that:

(a) No Other Relationship. The Underwriters have been retained solely to act as underwriters in connection with the sale of the Securities and that no fiduciary, advisory or agency relationship between the Company and the Underwriters have been created in respect of any of the transactions contemplated by the Terms Agreement (including these Standard Provisions incorporated by reference therein) or the Prospectus, irrespective of whether the Underwriters have advised or are advising the Company on other matters;

(b) Arm’s-Length Negotiations. The price of the Securities of each series set forth in the Terms Agreement was established by the Company following discussions and arm’s-length negotiations with the Representatives, and the Company is capable of evaluating and understanding and understands and accepts the terms, risks and conditions of the transactions contemplated by the Terms Agreement;

(c) Absence of Obligation to Disclose. The Company has been advised that the Underwriters and their affiliates are engaged in a broad range of transactions which may involve interests that differ from those of the Company, and that the Underwriters have no obligation to disclose such interests and transactions to the Company by virtue of any fiduciary, advisory or agency relationship; and

(d) Waiver. The Company waives, to the fullest extent permitted by law, any claims it may have against the Underwriters for breach of fiduciary duty or alleged breach of fiduciary duty and agrees that the Underwriters shall have no liability (whether direct or indirect) to the Company in respect of such a fiduciary duty claim or to any person asserting a fiduciary duty claim on behalf of or in right of the Company, including stockholders, employees or creditors of the Company.

Section 15. Patriot Act. In accordance with the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)), the Underwriters are required to obtain, verify and record information that identifies their respective clients, including the Company, which information may include the name and address of their respective clients, as well as other information that will allow the Underwriters to properly identify their respective clients.

Section 16. Waiver of Jury Trial. The Company and each of the Underwriters hereby irrevocably waives, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to the applicable Terms Agreement (including these Standard Provisions incorporated by reference therein) or the transactions contemplated hereby.

Section 17. Research Analyst Independence. The Company acknowledges that the Underwriters’ research analysts and research departments are required to be independent from their respective investment banking divisions and are subject to certain regulations and internal policies, and that such Underwriters’ research analysts may hold views and make statements or investment recommendations and/or publish research reports with respect to the Company and/or the offering that differ from the views of their respective investment banking divisions. The Company hereby waives and releases, to the fullest extent permitted by law, any claims that the Company may have against the Underwriters with respect to any conflict of interest that may arise from the fact that the views expressed by their independent research analysts and research departments may be different from or inconsistent with the views or advice communicated to the Company by such Underwriters’ investment banking divisions. The Company acknowledges that each of the Underwriters is a full service securities firm and as such from time to time, subject to applicable securities laws, may effect transactions for its own account or the account of its customers and hold long or short positions in debt or equity securities of the companies that may be the subject of the transactions contemplated by this Agreement.
