 The Class A(2005-9) Notes

the Indenture Supplement to be known as the “CHASEseries Class A(2005-9) Notes.” 
  
 Section 2.02 Specification of Required Subordinated Amount and Other Terms. 
  
 (a) For the Class A(2005-9) Notes for any date of determination, the Class A Required Subordinated Amount of Class B Notes will be an
amount equal to 7.80347% of (i) prior to the occurrence of a Class A(2005-9) Adverse Event, the Adjusted Outstanding Dollar Principal Amount of the Class A(2005-9) Notes on such date of determination or (ii) on and after the date on which a Class
A(2005-9) Adverse Event shall have occurred, the greater of (1) the Adjusted Outstanding Dollar Principal Amount of the Class A(2005-9) Notes on such date of determination and (2) the Adjusted Outstanding Dollar Principal Amount of the Class
A(2005-9) Notes as of the close of business on the day immediately preceding the date on which such Class A(2005-9) Adverse Event shall have occurred. 
  
 (b) For the Class A(2005-9) Notes for any date of determination, the Class A Required Subordinated Amount of Class C Notes will be an
amount equal to 7.80347% of (i) prior to the occurrence of a Class A(2005-9) Adverse Event, the Adjusted Outstanding Dollar Principal Amount of the Class A(2005-9) Notes on such date or (ii) on and after the date on which a Class A(2005-9) Adverse
Event shall have occurred, the greater of (1) the Adjusted Outstanding Dollar Principal Amount of the Class A(2005-9) Notes on such date of determination and (2) Adjusted Outstanding Dollar Principal Amount of the Class A(2005-9) Notes as of the
close of business on the day immediately preceding the date on which such Class A(2005-9) Adverse Event shall have occurred. 
  
 (c) The Issuer may change the percentages or the formulas set forth in either clause (a) or (b) above without the consent of any
Noteholder so long as the Issuer has (i) received written confirmation from each Note Rating Agency that has rated any Outstanding Class A(2005-9) Notes that the change in either of such percentages or formulas, as applicable, will not result in a
Ratings Effect with respect to any Outstanding Class A(2005-9) Notes and (ii) delivered to the Indenture Trustee and the Note Rating Agencies a Master Trust Tax Opinion and an Issuer Tax Opinion. 
  
 Section 2.03 Interest Payment. 
  
 (a) For each Interest Payment Date, the amount of interest
due with respect to the Class A(2005-9) Notes shall be an amount equal to the product of (i)(A) a fraction, the numerator of which is the actual number of days in the related 

  

 5 

 
Interest Period and the denominator of which is 360, times (B) the Note Interest Rate in effect with respect to the related Interest Period,
times, (ii) the Outstanding Dollar Principal Amount of the Class A(2005-9) Notes determined as of the close of business on the Interest Payment Date preceding the related Note Transfer Date for the Class A(2005-9) Notes; provided,
however, that for the first Interest Payment Date, the amount of interest due with respect to the Class A(2005-9) Notes shall be an amount equal to the product of (x) the Outstanding Dollar Principal Amount of the Class A(2005-9) Notes on the
Issuance Date, (y) 27 divided by 360 and (z) the Note Interest Rate in effect with respect to the Class A(2005-9) Notes determined on September 16, 2005. Interest on the Class A(2005-9) Notes will be calculated on the basis of the actual number of
days elapsed and a 360-day year. 
  
 (b) Pursuant
to Section 3.03 of the Indenture Supplement, on each Note Transfer Date with respect to the Class A(2005-9) Notes, the Indenture Trustee shall deposit into the Class A(2005-9) Interest Funding Sub-Account the portion of CHASEseries Available Finance
Charge Collections allocable to the Class A(2005-9) Notes. 
  
 Section 2.04 Calculation Agent; Determination of LIBOR. 
  
 (a) The Issuer hereby agrees that for so long as any Class A(2005-9) Notes are Outstanding, there shall at all times be an agent appointed
to calculate LIBOR for each Interest Period (the “Calculation Agent”). The Issuer hereby initially appoints the Indenture Trustee as the Calculation Agent for purposes of determining LIBOR for each Interest Period. The Calculation Agent
may be removed by the Issuer at any time. If the Calculation Agent is unable or unwilling to act as such or is removed by the Issuer, or if the Calculation Agent fails to determine LIBOR for an Interest Period, the Issuer shall promptly appoint a
replacement Calculation Agent that does not control or is not controlled by or under common control with the Issuer or its Affiliates. The Calculation Agent may not resign its duties, and the Issuer may not remove the Calculation Agent, without a
successor having been duly appointed. 
  
 (b) On
each LIBOR Determination Date, the Calculation Agent shall determine LIBOR on the basis of the rate for deposits in United States dollars for a one-month period which appears on Telerate Page 3750 or on such comparable system as is customarily used
to quote LIBOR as of 11:00 a.m., London time, on such date. If such rate does not appear on Telerate Page 3750 or on a comparable system as is customarily used to quote LIBOR the rate for that LIBOR Determination Date shall be determined on the
basis of the rates at which deposits in United States dollars are offered by the Reference Banks at approximately 11:00 a.m., London time, on that day to prime banks in the London interbank market for a one-month period. The Calculation Agent shall
request the principal London office of each of the Reference Banks to provide a quotation of its rate. If at least two such quotations are provided, the rate for that LIBOR Determination Date shall be the arithmetic mean of the quotations. If fewer
than two quotations are provided as requested, the rate for that LIBOR Determination Date will be the arithmetic mean of the rates quoted by major banks in New York City, selected by the 

  

 6 

 
Beneficiary, at approximately 11:00 a.m., New York City time, on that day for loans in United States dollars to leading European banks for a one-month
period. 
  
 (c) The Note Interest Rate applicable
to the then current and the immediately preceding Interest Periods may be obtained by telephoning the Indenture Trustee at its corporate trust office at (612) 667-8058 or such other telephone number as shall be designated by the Indenture Trustee
for such purpose by prior written notice by the Indenture Trustee to each Noteholder from time to time. 
  
 (d) On each LIBOR Determination Date, the Calculation Agent shall send to the Indenture Trustee and the Beneficiary, by facsimile
transmission, notification of LIBOR for the following Interest Period. 
  
 Section 2.05 Payments of Interest and Principal. 
  
 (a) Any installment of interest or principal payable on any Class A(2005-9) Note which is punctually paid or duly provided for by the Issuer and the Indenture Trustee on the applicable Interest Payment Date or
Principal Payment Date shall be paid by the Paying Agent to the Person in whose name such Class A(2005-9) Note (or one or more Predecessor Notes) is registered on the Record Date, by wire transfer of immediately available funds to such Person’s
account as has been designated by written instructions received by the Paying Agent from such Person not later than the close of business on the third Business Day preceding the date of payment or, if no such account has been so designated, by check
mailed first-class, postage prepaid to such Person’s address as it appears on the Note Register on such Record Date, except that with respect to Notes registered on the Record Date in the name of the nominee of Cede & Co., payment shall be
made by wire transfer in immediately available funds to the account designated by such nominee. 
  
 (b) The right of the Class A(2005-9) Noteholders to receive payments from the Issuer will terminate on the first Business Day following
the Class A(2005-9) Termination Date. 
  
 Section 2.06 Form of
Delivery of Class A(2005-9) Notes; Depository; Denominations. 
  
 (a) The Class A(2005-9) Notes shall be delivered in the form of a global Registered Note as provided in Sections 2.02 and 3.01(i) of the Indenture, respectively. 
  
 (b) The Depository for the Class A(2005-9) Notes shall be
The Depository Trust Company, and the Class A(2005-9) Notes shall initially be registered in the name of Cede & Co., its nominee. 
  
 (c) The Class A(2005-9) Notes will be issued in minimum denominations of $1,000 and integral multiples of that amount. 
  

 7 

 Section 2.07 Delivery and Payment for the Class A(2005-9) Notes. The Issuer shall execute and
deliver the Class A(2005-9) Notes to the Indenture Trustee for authentication, and the Indenture Trustee shall deliver the Class A(2005-9) Notes when authenticated, each in accordance with Section 3.03 of the Indenture. 
  
 Section 2.08 Supplemental Indenture. The Issuer may enter into a
supplemental indenture with respect to the Class A(2005-9) Notes as provided in Section 9.01 of the Indenture; provided, however, that any supplemental indenture which provides for an additional or alternative form of credit
enhancement for the Class A(2005-9) Notes shall, in addition to the requirements set forth in Section 9.01 of the Indenture, require confirmation from the Note Rating Agencies that have rated any Outstanding Notes of the CHASEseries that such change
in credit enhancement will not result in a Ratings Effect with respect to any Outstanding Notes of the CHASEseries. 
  
 Section 2.09 Appointment of co-Paying Agent and co-Transfer Agent. BDL is appointed as co-paying agent and as co-transfer agent in Luxembourg with
respect to the Class A(2005-9) Notes for so long as the Class A(2005-9) Notes are listed on the Luxembourg Stock Exchange. Any reference in this Terms Document, the Indenture Supplement, the Asset Pool Supplement and the Indenture to the Paying
Agent or the Transfer Agent shall be deemed to include BDL as co-paying agent or co-transfer agent, as the case may be, unless the context requires otherwise.

	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. 

  

	 	(b)	 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 

  

 18 

	 	 
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. 

  

	 	(c)	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 

  

 19 

	 	 
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, the Chase 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 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 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 

  

 20 

	 	 
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 of this Agreement. 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, 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 Prospectus or in any other documents or arrangements. 
  

	13.	If for any reason other than as set forth in Section 12 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 7 of this Agreement and the respective obligations of the Bank, the Issuer, and the Underwriters pursuant to Sections 9 and 10 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 clauses (ii), (iv) or (v) of Section 11 of this Agreement, 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 J.P.
Morgan Securities Inc. at 270 Park Avenue, Floor 10, New York, New York 10017, Attention: Eric Wiedelman, or to such other address as the Representative may designate in writing to the Bank. Notices to the Bank shall be given to it at 201 North
Walnut Street, Wilmington, Delaware 19801, Attention: David Penkrot, Senior Vice President, telephone: (302) 282-7450, telecopier: (302) 282-6605, with a copy to JPMorgan Chase & Co., 1 Bank One Plaza, Mail Suite IL1-0460, Chicago, Illinois
60670, Attention: Stephen R. Etherington, Senior Vice President -Structured Finance, telephone: (312) 732-1893, telecopier: (312) 732-3366. 

  

	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 12, 1994, addressed to Kidder, Peabody Acceptance Corporation I, Kidder, Peabody & Co.
Incorporated and Kidder Structured 

  

 21 

	 	 
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 12, 1994), with respect to the offering of the Notes. 

  

	 	(b)	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.	The Bank acknowledges and agrees that the Underwriters are acting solely in the capacity of an arm’s length contractual counterparty to the Bank with respect to the offering of
Notes contemplated hereby (including in connection with determining the terms of the offering) and not as a financial advisor or a fiduciary to, or an agent of, the Bank or any other person. Additionally, neither the Representative nor any other
Underwriter is advising the Bank or any other person as to any legal, tax, investment, accounting or regulatory matters in any jurisdiction. The Bank shall consult with its own advisors concerning such matters and shall be responsible for making
their own independent investigation and appraisal of the transactions contemplated hereby, and the Underwriters shall have no responsibility or liability to the Bank with respect thereto. Any review by the Underwriters of the Bank, the transactions
contemplated hereby or other matters relating to such transactions will be performed solely for the benefit of the Underwriters and shall not be on behalf of the Bank. 

  

 22 

	20.	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.
