Ladies and Gentlemen:

Bank One Issuance Trust, a Delaware statutory trust (the “Issuer”), and Bank One, Delaware, National Association (formerly known as First USA Bank, National Association) (the “Bank”), as originator (in such capacity, the “Originator”) and beneficiary (in such capacity, the “Beneficiary”) of the Issuer, propose to sell the notes of the series, classes and tranches designated in the applicable Terms Agreement (as hereinafter defined) (the “Notes”). The Notes will be issued pursuant to the Indenture, as supplemented by the Asset Pool One Supplement and the Indenture Supplement, each dated as of May 1, 2002, and a Terms Document having the date stated in the applicable Terms Agreement (as so supplemented and as otherwise modified or amended from time to time, the “Indenture”), between the Issuer and Xxxxx Fargo Bank Minnesota, National Association, as trustee (in such capacity, the “Indenture Trustee”). The Issuer will be operated pursuant to an Amended and Restated Trust Agreement, dated as of May 1, 2002, between the Bank, as Beneficiary, and Wilmington Trust Company, as owner trustee (the “Owner Trustee”) (the “Trust Agreement”). The Notes will be secured pursuant to the Asset Pool One Supplement, dated as of May 1, 2002 between the Issuer and Xxxxx Fargo Bank Minnesota, National Association, as collateral agent (the “Collateral Agent”) (the “Asset Pool Supplement”) by certain assets of the Issuer, initially including the Collateral Certificate and, subsequently, possibly including Receivables, as discussed below (the “Collateral”).

The Bank transfers credit card receivables to the First USA Credit Card Master Trust (the “First USA Credit Card Master Trust”) pursuant to an Amended and Restated Pooling and

Servicing Agreement, dated as of March 28, 2002 (as may be further amended from time to time, the “Pooling and Servicing Agreement”), as supplemented by the applicable Series Supplement (the “Series Supplement”; references herein to the Pooling and Servicing Agreement shall mean, unless otherwise specified, the Pooling and Servicing Agreement as supplemented by the Series Supplement), having the date stated in the applicable Terms Agreement, among the Bank, as transferor (in such capacity, the “Transferor”) and as servicer (in such capacity, the “Servicer”), and The Bank of New York (Delaware), as trustee (in such capacity, the “First USA Master Trust Trustee”). The assets of the First USA Credit Card Master Trust include, among other things, receivables (“Receivables”) arising under certain revolving credit card accounts (the “Accounts”). Pursuant to the Pooling and Servicing Agreement and the Transfer and Servicing Agreement, among the Bank, as Transferor, Servicer and Administrator, and the Issuer, dated as of May 1, 2002 (as amended from time to time, the “Transfer and Servicing Agreement”), the Bank has caused the First USA Credit Card Master Trust to issue to the Issuer a collateral certificate (the “Collateral Certificate”). The Collateral Certificate is an investor certificate under the Pooling and Servicing Agreement that represents undivided interests in certain assets of the First USA Credit Card Master Trust.

The Notes designated in the applicable Terms Agreement will be sold in a public offering by the Issuer through Banc One Capital Markets, Inc., as the representative of the underwriters listed on Schedule I to the applicable Terms Agreement (any underwriter through which Notes are sold shall be referred to herein as an “Underwriter” or, collectively, all such Underwriters may be referred to as the “Underwriters;” each representative thereof may be referred to herein together as “Representative,” which, if the context herein does require, shall include Banc One Capital Markets, Inc. in its capacity as Underwriter of any Notes or as Representative). Notes sold to the Underwriters for which Banc One Capital Markets, Inc. is the Representative shall be sold pursuant to a Terms Agreement by and between the Bank, the Trust and the Representative, a form of which is attached hereto as Exhibit A (a “Terms Agreement”), which incorporates by reference this Underwriting Agreement (the “Agreement,” which may include the applicable Terms Agreement if the context so requires). Any Notes sold pursuant to any Terms Agreement may include the benefits of a reserve account, letter of credit, surety bond, cash collateral account, cash collateral guaranty, collateral interest, guaranteed rate agreement, maturity guaranty facility, tax protection agreement, interest rate swap, spread account or other contract or agreement for the benefit of the Noteholders of such Series (“Credit Enhancement”). The term “applicable Terms Agreement” means the Terms Agreement dated the date hereof. To the extent not defined herein, capitalized terms used herein have the meanings assigned to such terms in the Indenture or the Pooling and Servicing Agreement. Unless otherwise stated herein or in the applicable Terms Agreement, as the context otherwise requires or if such term is otherwise defined in the Indenture or the Pooling and Servicing Agreement, each capitalized term used or defined herein or in the applicable Terms Agreement shall relate only to the Notes designated in the applicable Terms Agreement and no other Series, Class or Tranche of Notes issued by the Issuer.

The Bank has prepared and filed with the Securities and Exchange Commission (the “Commission”) in accordance with the provisions of the Securities Act of 1933, as amended, and the rules and regulations of the Commission thereunder (collectively, the “Act”), a shelf registration

statement on Form S-3 (having the registration number stated in the applicable Terms Agreement), including a form of prospectus, relating to the Notes and the Collateral Certificate. The registration statement as amended has been declared effective by the Commission. If any post-effective amendment has been filed with respect thereto, prior to the execution and delivery of the applicable Terms Agreement, the most recent such amendment has been declared effective by the Commission. Such registration statement, as amended at the time of effectiveness, including all material incorporated by reference therein and including all information (if any) deemed to be part of the registration statement at the time of effectiveness pursuant to Rule 430A under the Act, is referred to in this Agreement as the “Registration Statement.” The Bank proposes to file with the Commission pursuant to Rule 424(b) (“Rule 424(b)”) under the Act a supplement (the “Prospectus Supplement”) to the prospectus included in the Registration Statement (such prospectus, in the form it appears in the Registration Statement or in the form most recently revised and filed with the Commission pursuant to Rule 424(b) is hereinafter referred to as the “Basic Prospectus”) relating to the Notes and the method of distribution thereof. The Basic Prospectus and the Prospectus Supplement, together with any amendment thereof or supplement thereto, is hereinafter referred to as the “Prospectus.”

9. (a) The Bank and the Issuer, 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 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 related preliminary 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 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 none of the Bank or the Issuer 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 Issuer by any Underwriter specifically for use therein or any revision or amendment thereof or supplement thereto.

The foregoing indemnity with respect to any untrue statement or omission in any preliminary prospectus or prospectus supplement shall not inure to the benefit of any Underwriter (or to the benefit of any person controlling such Underwriter) from whom the person asserting any such losses, claims, damages or liabilities purchased Notes if a copy of the Prospectus (as then amended or supplemented if the Bank or the Issuer shall have furnished any amendments or supplements thereto) was not sent or given by or on behalf of such Underwriter to such person, if such is required by law, at or prior to the written confirmation of the sale of such Notes to such person and if the Prospectus (as so amended or supplemented) would have cured the defect giving rise to such loss, claim, damage or liability provided that the Bank or the Issuer shall have identified to such Underwriter in writing such defect prior to the delivery of such written confirmation by such Underwriter to such person.

(1) 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 Issuer and each person, if any, who controls the Bank or the Issuer 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 omissions, or alleged untrue statements of any material fact or omissions, made in the Registration Statement, the Prospectus, or in any revision or amendment thereof or supplement thereto or any related preliminary prospectus or prospectus supplement, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Bank or the Issuer by such Underwriter through the Representative expressly for use in the Registration Statement or such preliminary prospectus or the Prospectus, or any revision or amendment thereof or supplement thereto and agrees to reimburse such indemnified party for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage or liability or action as such expenses are incurred.

(2) 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 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.

10. In order to provide for just and equitable contribution in circumstances in which the indemnity agreement provided for in Section 9(a) is for any reason held to be unavailable

other than in accordance with its terms, the Bank and the Issuer 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 Issuer 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 Issuer are jointly and severally responsible for the balance. Notwithstanding the provisions of this Section 10, each Underwriter shall not 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 10 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 Section 10. 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, 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.

11. 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 not have occurred (i) any change, or any development involving a prospective change, in or affecting particularly the business or properties of the Owner Trust, the First USA Credit Card Master Trust 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 BANK ONE CORPORATION 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 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.

12. 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 7. Nothing herein will relieve a defaulting Underwriter from liability for its default.

In the event of any such default which does not result in a termination of this Agreement, any of 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 Prospectus or in any other documents or arrangements.

13. If for any reason other than as set forth in Section 12 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 7 and the respective obligations of the Bank, the Issuer, and the Underwriters pursuant to Sections 9 and 10 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 clauses (ii), (iv) or (v) of Section 11, the Bank 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 Notes.

14. 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. 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 given to Banc One Capital Markets Inc., as Representative at 1 Bank Xxx Xxxxx, Xxxx Xxxxx, XX0-0000, Xxxxxxx, Xxxxxxxx 00000, Attention: Xxxxxx X.

15. (a) Except as specifically set forth in the applicable Terms Agreement, each Underwriter, severally, represents and warrants to the Bank and the Issuer that it has not and will not use any information that constitutes “Computational Materials,” as defined in the Commission’s No-Action Letter, dated May 20, 1994, addressed to Xxxxxx, Peabody Acceptance Corporation I, Xxxxxx, Xxxxxxx & Co. Incorporated and Xxxxxx Structured Asset Corporation (as made generally applicable to registrants, issuers and underwriters by the Commission’s response to the request of the Public Securities Association dated May 27, 1994), with respect to the offering of the Notes.

(1) Except as specifically set forth in the applicable Terms Agreement, each Underwriter, severally, represents and warrants to the Bank and the Issuer that it has not and will not use any information that constitutes “ABS Term Sheets,” as defined in the Commission’s No-Action Letter, dated February 13, 1995, addressed to the Public Securities Association, with respect to the offering of the Notes.

16. Each Underwriter, severally, represents that it will not, at any time that such Underwriter is acting as an “underwriter” (as defined in Section 2(11) of the Act) with respect to the Notes, transfer, deposit or otherwise convey any Notes into a trust or other type of special purpose vehicle that is sponsored by such Underwriter or an Affiliate of such Underwriter and that issues securities or other instruments backed in whole or in part by, or that represents interests in, such Notes without the prior written consent of the Bank.

17. This Agreement shall become effective upon execution and delivery of the applicable Terms Agreement.

18. This Agreement shall inure to the benefit of and be binding upon the Bank, the Issuer, the Underwriters, any controlling persons referred to herein and their respective successors and assigns. Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any other person, firm or corporation any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision herein contained. No purchaser of Notes from any Underwriter shall be deemed to be a successor by reason merely of such purchase.

19. This Agreement may be signed in counterparts, each of which shall be an original and all of which together shall constitute one and the same instrument. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT GIVING EFFECT TO THE CONFLICT OF LAWS PROVISIONS THEREOF.

If the foregoing is in accordance with your understanding of our agreement, kindly sign and return to us the enclosed duplicate hereof, whereupon it will become a binding agreement between the Bank, the Issuer and the Underwriters in accordance with its terms.
