(a) Indemnification of the Underwriters. The Bank and the Issuing Entity, jointly and severally, agree to indemnify and hold harmless each Underwriter and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Act and under Section 20 of the Exchange Act against any and all losses, claims, damages or liabilities to which they may become subject insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or based upon (1) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Prospectus (or in any revision or amendment thereof or supplement thereto) or any Preliminary Prospectus, or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, or (2) any untrue statement or alleged untrue statement of a material fact contained in any Issuer Free Writing Prospectus or any Issuing Entity Information (as defined in subsection 9(c)) contained in any Underwriter Free Writing Prospectus (as defined in subsection 9(c)) or in any Free Writing Prospectus for which the Bank or any person acting on its behalf provided, authorized or approved information that is prepared and published or disseminated by a person unaffiliated with the Bank or any other

19

offering participant that is in the business of publishing radio or television broadcasting or otherwise disseminating communications, or the omission or alleged omission to state a material fact required to make the statements therein, in light of the circumstances under which they were made, not misleading, and agrees to reimburse each such indemnified party for any legal or other expense reasonably incurred by it in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that neither the Bank nor the Issuing Entity will be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to the Bank or the Issuing Entity by any Underwriter specifically for use therein or any revision or amendment thereof or supplement thereto.

(b) Indemnification of the Bank and the Issuing Entity. Each Underwriter severally and not jointly agrees to indemnify and hold harmless the Bank, its directors, each of its officers who signed the Registration Statement, the Issuing Entity and each person, if any, who controls the Bank or the Issuing Entity within the meaning of Section 15 of the Act and under Section 20 of the Exchange Act against any and all losses, claims, damages or liabilities to which they may become subject insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statements or alleged untrue statements of any material fact contained in the Registration Statement, the Prospectus, or in any revision or amendment thereof or supplement thereto, any related Preliminary Prospectus or any Free Writing Prospectus, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made (i) in reliance upon and in conformity with written information furnished to the Bank or the Issuing Entity by such Underwriter through the Representative expressly for use in the Registration Statement, any Free Writing Prospectus, Preliminary Prospectus or the Prospectus (or any revision or amendment thereof or supplement thereto) or (ii) in any Underwriter Free Writing Prospectus and agrees to reimburse each such indemnified party for any legal or other expenses reasonably incurred by it in connection with investigating or defending any such loss, claim, damage or liability or action as such expenses are incurred; provided, that no Underwriter shall be obligated to so indemnify and hold harmless an indemnified party to the extent such losses, claims, damages or liabilities are caused by a misstatement or omission resulting from an error or omission in (A) the Issuing Entity Information (as hereinafter defined) which was not corrected by Issuing Entity Information subsequently supplied by the Bank or the Issuing Entity to the Underwriter at any time prior to the Time of Sale, or (B) the information contained in the Prospectus or Time of Sale Information.

20

(c) Indemnification Procedures. Each indemnified party shall give prompt written notice to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability which it may have otherwise than on account of this indemnity agreement; provided, that the indemnifying party is not materially prejudiced by such failure to so notify. An indemnifying party may participate at its own expense in the defense of any such action. In no event shall the indemnifying parties be liable for fees and expenses of more than one counsel separate from their own counsel for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances. 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 (x) includes an unconditional release of such indemnified party from all liability on any claims that are the subject matter of such action and (y) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

(d) Contribution and Limitation on Liability. In order to provide for just and equitable contribution in circumstances in which the indemnity agreement provided for in subsection 8(a) is for any reason held to be unavailable other than in accordance with its terms, the Bank and the Issuing Entity and the Underwriters shall contribute to the aggregate losses, liabilities, claims, damages and expenses of the nature contemplated by said indemnity agreement incurred by the Bank and the Issuing Entity and the Underwriters, as incurred, in such proportions that the Underwriters are responsible for that portion represented by the percentage that the underwriting discount and commissions bear to the initial public offering price appearing thereon and the Bank and the Issuing Entity are jointly and severally responsible for the balance. Notwithstanding the provisions of this subsection 8(d), no Underwriter shall be required to contribute any amount in excess of the underwriting discount or commission applicable to the Notes purchased by it hereunder. The Bank and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 8 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 any of the equitable considerations referred to above in this subsection 8(d). 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. For purposes of this Section 8, each person, if any, who controls an Underwriter within the meaning of Section 15 of the Act shall have the same rights to contribution as such Underwriter, and each director of the Bank, each officer of the Bank who signed the Registration Statement, and each person, if any, who controls the Bank within the meaning of Section 15 of the Act shall have the same rights to contribution as the Bank.

21

(e) Static Pool Information. For clarification purposes, in this Section 8 only, it is understood that the terms “Preliminary Prospectus” and “Prospectus” include static pool information required to be disclosed pursuant to Item 1105 of Regulation AB under the Act, without regard to whether such information is deemed to be a part of a prospectus under Item 1105(d) of Regulation AB under the Act.

Section 9. Offering Communications; Free Writing Prospectuses and ABS Informational and Computational Materials.

(a) Except as generally set forth in the applicable Terms Agreement, each Underwriter, severally, represents, warrants and agrees with the Bank and the Issuing Entity that it has not distributed and will not distribute any written materials that would be treated as “ABS informational and computational material”, as defined in Item 1101(a) of Regulation AB under the Act (“ABS Informational and Computational Material”). If the Bank and the Issuing Entity shall have agreed pursuant to the applicable Terms Agreement to the use of any Free Writing Prospectus, the provisions of this Section 9 shall apply with respect thereto.

(b) Each Underwriter severally represents, warrants and agrees with the Bank and the Issuing Entity that other than the Preliminary Prospectus and the final Prospectus, it has not conveyed and will not convey, without the Bank’s prior written approval, to any potential investor in the Notes any other written material of any kind containing any “issuer information” as defined in Rule 433(h)(2) of the Act, that would constitute a “prospectus” or a “free writing prospectus”, each as defined in the Act, including, but not limited to any ABS Informational and Computational Materials; provided, however, each Underwriter may convey to one or more of its potential investors a Free Writing Prospectus containing only information permitted under Rule 134 of the Act, including bona fide estimates of the price range for the Notes and the final price of the Notes and information previously included in the Preliminary Prospectus, as well as a column or other entry showing the status of the subscriptions for each tranche of the Notes and/or expected pricing parameters of the Notes.

(c) Each Underwriter severally represents and warrants to the Bank and the Issuing Entity that each Free Writing Prospectus prepared by or on behalf of an Underwriter which is not listed on Annex I (each an “Underwriter Free Writing Prospectus”) did not, as of the date such Free Writing Prospectus was conveyed or delivered to any potential investor in the Notes, include any untrue statement of a material fact or omit any material fact necessary to make the statements contained therein, in light of the circumstances under which they were made, not misleading; provided, however, that such Underwriter makes no representation to the extent such misstatements or omissions were the result of any inaccurate information which was publicly available or provided to such Underwriter by the Bank or the Issuing Entity (such information, “Issuing Entity Information”), which information was not corrected by Issuing Entity Information subsequently supplied by the Bank or the Issuing Entity to such Underwriter prior to the Time of Sale.

22

(d) The Bank, the Issuing Entity and the Underwriters each agrees that any Free Writing Prospectus prepared by it shall contain the legend required by Rule 433 under the Act.

Section 10. Termination. Notwithstanding anything herein contained, this Agreement and the applicable Terms Agreement may be terminated in the absolute discretion of the Representative, by notice given to the Bank, if after the execution and delivery of this Agreement and the applicable Terms Agreement and prior to the Closing Date there shall have occurred (i) any change, or any development involving a prospective change, in or affecting particularly the business or properties of the Issuing Entity or the Bank which, in the judgment of the Representative, materially impairs the investment quality of the Notes or makes it impractical or inadvisable to market the Notes; (ii) any suspension or limitation on trading in securities generally on the New York Stock Exchange or the National Association of Securities Dealers National Market System, or any setting of minimum prices for trading on such exchange or market system; (iii) any suspension of trading of any securities of JPMorgan Chase & Co. on any exchange or in the over-the-counter market which materially impairs the investment quality of the Notes or makes it impractical or inadvisable to market the Notes; (iv) any banking moratorium declared by Federal, Delaware or New York authorities; or (v) any outbreak or escalation of major hostilities or armed conflict, any declaration of war by Congress, or any other substantial national or international calamity or emergency if, in the reasonable judgment of the Representative, the effect of any such outbreak, escalation, declaration, calamity, or emergency makes it impractical or inadvisable to proceed with completion of the sale of and payment for the Notes.

Section 11. Defaulting Underwriter.

(a) If any Underwriter defaults in its obligations to purchase Notes hereunder and the aggregate principal amount of the Notes that such defaulting Underwriter agreed but failed to purchase does not exceed 10% of the total principal amount of such Notes, the Representative may make arrangements satisfactory to the Bank for the purchase of such Notes by other persons, including the non-defaulting Underwriters, but if no such arrangements are made by the Closing Date, the non-defaulting Underwriters shall be obligated, in proportion to their commitments hereunder, to purchase the Notes that such defaulting Underwriter agreed but failed to purchase. If any Underwriter so defaults and the aggregate principal amount of the Notes with respect to which such default or defaults occur exceeds 10% of the total principal amount of such Notes and arrangements satisfactory to the Representative and the Bank for the purchase of such Notes by other persons are not made within 36 hours after such default, this Agreement will terminate without liability on the part of any non-defaulting Underwriter or the Bank, except as provided in Section 8 of this Agreement. Nothing herein will relieve a defaulting Underwriter from liability for its default.

23

(b) In the event of any such default which does not result in a termination of this Agreement, either the Representative or the Bank shall have the right to postpone the Closing Date for a period not exceeding seven days in order to effect any required changes in the Registration Statement or the Prospectus or in any other documents or arrangements.

Section 12. Reimbursement of Expenses. If for any reason other than as set forth in Section 11 of this Agreement the purchase of the Notes by the Underwriters is not consummated, the Bank shall remain responsible for the expenses to be paid or reimbursed by it pursuant to Section 6 of this Agreement and the respective obligations of the Bank, the Issuing Entity, and the Underwriters pursuant to Sections 7 and 8 of this Agreement shall remain in effect. If the purchase of the Notes by the Underwriters is not consummated for any reason other than solely because of the occurrence of any event specified in clause (ii), (iv) or (v) of Section 10 of this Agreement, the Bank will reimburse the Underwriters for all out-of-pocket expenses (including fees and disbursements of counsel for the Underwriters) reasonably incurred by them in connection with the offering of the Notes.

Section 13. Notices. Any action by the Underwriters hereunder may be taken by the Representative on behalf of the Underwriters, and any such action taken by the Representative shall be binding upon the Underwriters.
