     Letter and the PSA Letter, the "No-Action Letters").
                                     -----------------   

              (ii)   Each Underwriter, severally, represents and warrants to the
     Bank that (a) it has not and will not use any information that constitutes
     "Computational Materials" with respect to the offering of the Certificates
     unless it has obtained the prior written consent of the Bank to such usage
     and (b) other than the 1997-10 Term Sheet, it has not and will not use any
     information that constitutes "Series Term Sheets," "ABS Term Sheets,"
     "Structural Term Sheets," or "Collateral Term Sheets" with respect to the
     offering of the Certificates.  For purposes hereof, "Series Term Sheet"
                                                          -----------------

          4.  Certain Agreements of the Bank.  The Bank covenants and agrees
              ------------------------------                                
with the several Underwriters as follows:

              (a)    Immediately following the execution of this Agreement, the
Bank will prepare a Prospectus Supplement setting forth the amount of
Certificates covered thereby and the terms thereof not otherwise specified in
the Basic Prospectus, the price at which such Certificates are to be purchased
by the Underwriters, the initial public offering price, the selling concessions
and allowances, and such other information as the

                                       8
<PAGE>
 
Bank deems appropriate.  The Bank will transmit the Prospectus including such
Prospectus Supplement to the Commission pursuant to Rule 424(b) by a means
reasonably calculated to result in filing that complies with all applicable
provisions of Rule 424(b).  The Bank will advise the Representative promptly of
any such filing pursuant to Rule 424(b).

              (b)  The Bank will advise the Representative promptly of any
proposal to amend or supplement the Registration Statement or the Prospectus and
will not effect such amendment or supplement without the consent of the
Representative, which consent will not unreasonably be withheld; the Bank will
also advise the Representative promptly of any request by the Commission for
any amendment of or supplement to the Registration Statement or the Prospectus
or for any additional information; and the Bank will also advise the
Representative promptly of any amendment or supplement to the Registration
Statement or the Prospectus and of the issuance by the Commission of any stop
order suspending the effectiveness of the Registration Statement or the
institution or threat of any proceeding for that purpose and the Bank will use
its best efforts to prevent the issuance of any such stop order and to obtain as
soon as possible the lifting of any issued stop order.

              (c)  If, at any time when a prospectus relating to the
Certificates is required to be delivered under the Act, any event occurs as a
result of which the Prospectus as then amended or supplemented would include an
untrue statement of a material fact or omit to state any material fact necessary
to make the statements therein, in the light of the circumstances under which
they were made, not misleading, or if it is necessary at any time to amend or
supplement the Prospectus to comply with the Act, the Bank promptly will advise
the Representative thereof and will prepare and file, or cause to be prepared
and filed, with the Commission an amendment or supplement which will correct
such statement or omission, or an amendment or supplement which will effect such
compliance. Any such filing shall not operate as a waiver or limitation on any
condition or right of the Underwriters hereunder.

              (d)  As soon as practicable, but not later than sixteen months
after the original effective date of the Registration Statement, the Bank will
cause the Trust to make generally available to Certificateholders an earnings
statement (or statements) of the Trust covering a period of at least twelve
months beginning after the effective date of the Registration Statement which
will satisfy the provisions of Section 11(a) of the Act and Rule 158 promulgated
thereunder.

                                       9
<PAGE>
 
              (e)  The Bank will furnish to the Underwriters copies of the
Registration Statement (one of which will be signed and will include all
exhibits), each related preliminary prospectus or prospectus supplement, the
Prospectus and all amendments and supplements to such documents, in each case as
soon as available and in such quantities as the Underwriters request.

              (f)  The Bank will promptly, from time to time, take such action
as any Underwriter may reasonably request to qualify the Certificates for
offering and sale under the securities laws of such jurisdictions as such
Underwriter may request and to comply with such laws so as to permit the
continuance of sales and dealings therein in such jurisdictions for as long as
may be necessary to complete the distribution of the Certificates, provided that
in connection therewith the Bank shall not be required to qualify as a foreign
corporation or dealer in securities or to file a general consent to service of
process in any jurisdiction.

              (g)  For a period from the date of this Agreement until the
retirement of the Certificates, the Bank will deliver to the Representative the
annual statements of compliance and the annual independent certified public
accountants' reports furnished to the Trustee pursuant to the Pooling and
Servicing Agreement, as soon as such statements and reports are furnished to the
Trustee.

              (h)  So long as any of the Certificates are outstanding, the Bank
will furnish to the Representative (i) as soon as practicable after the end of
the fiscal year all documents required to be distributed to Certificateholders
or filed with the Commission pursuant to the Securities Exchange Act of 1934, as
amended (the "Exchange Act"), or any order of the Commission thereunder and (ii)
              ------------                                                      
from time to time, any other information concerning the Bank filed with any
government or regulatory authority which is otherwise publicly available, as the
Representative reasonably requests.

              (i)  To the extent, if any, that the rating provided with respect
to the Certificates by the rating agency or agencies that initially rate the
Certificates is conditional upon the furnishing of documents or the taking of
any other actions by the Bank, the Bank shall use its best efforts to furnish
such documents and take any such other actions.

              (j)  The Bank will file with the Commission a report on Form 8-K
with respect to the 1997-10 Term Sheet and a report on Form 8-K setting forth
all Computational Materials

and identified by such Underwriter as such within the time period allotted for
such filing pursuant to the No-Action Letters.

          5.  Payment of Expenses.  The Bank will pay all expenses incident to
              -------------------

4(f) hereof, including filing fees and the fees and disbursements of counsel for
the Underwriters and in connection with the preparation of any blue sky and
legal investment survey, (vii) the printing and delivery to the Underwriters of
copies of the 1997-10 Term Sheet and any Computational Materials described in
Section 3 hereof, (viii) the printing and delivery to the Underwriters of copies
of the Prospectus and of each amendment or supplement thereto, (ix) the printing
and delivery to the Underwriters of copies of any blue sky or legal investment
survey prepared in connection with the Certificates, (x) any fees charged by
rating agencies for the rating of the Certificates, (xi) the fees and expenses,
if any, incurred with respect to any filing with the National Association of
Securities Dealers, Inc. and (xii) the fees and expenses of the Trustee and its
counsel.  The Underwriters have agreed to reimburse the Bank for expenses not to
exceed $190,813 incurred by the Bank in connection with the issuance and
distribution of the Certificates.

          6.  Conditions of the Obligations of the Underwriters.  The
              -------------------------------------------------      
obligations of the several Underwriters to purchase and pay for the Certificates
will be subject to the accuracy of the representations and warranties on the
part of the Bank herein, to the accuracy of the statements of officers of the
Bank made pursuant to the provisions hereof, to the performance by the Bank of
its obligations hereunder and to the following additional conditions precedent:

              (b)  On or prior to the date of the Prospectus and on or prior to

counsel.

              (c)  Subsequent to the execution and delivery of this Agreement,
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 Trust, or the Bank which, in the judgment of the Representative, materially
impairs the investment quality of the Certificates or makes it impractical or

Association of Securities Dealers National Market system, or any setting of

completion of the sale of and payment for the Certificates.

Representative certificates of a vice president or more senior officer of the

              (e)  Joanne Sundheim, Associate General Counsel of First USA Bank,
shall have furnished to the Representative her written opinion, addressed to the
Representative and dated the Closing Date, in form and substance satisfactory to
the Representative and its counsel, substantially to the effect that:

                   (i)   The Bank has been duly incorporated and is validly
          existing as a bank in good standing under the laws of the State of
          Delaware with full power and authority (corporate and other) to own
          its properties and conduct its business, as presently owned and
          conducted by it, and to enter into and perform its obligations under
          this Agreement, the CIA Agreement and the Pooling and Servicing
          Agreement (collectively referred to in this subsection (e) as the
          "Agreements"), and the Certificates and had at all times, and now has,
           ----------
          the power, authority and legal right to acquire, own and transfer the
          Receivables;

                   (ii)  The Bank is duly qualified to do business and is in
          good standing, and under state laws, as they are currently interpreted
          and enforced, has obtained all necessary licenses and approvals in
          each jurisdiction in which failure to qualify or to obtain such
          licenses or approvals would materially and adversely affect the
          enforce ability of any Receivable by the Bank or the Trustee or would
          adversely affect the ability of the Bank to perform its obligations
          under the Agreements or the Certificates;

                   (iii) The Certificates have been duly authorized, executed
          and delivered by the Bank and, when duly authenticated by the Trustee
          in accordance with the terms of the Pooling and Servicing Agreement
          and delivered to and paid for by the Underwriters in accordance with
          the terms of this Agreement, will be validly issued and outstanding
          and entitled to the benefits provided by the Pooling and Servicing
          Agreement;

                   (iv)  Each of the Agreements has been duly authorized,
          executed and delivered by the Bank and constitutes the legal, valid
          and binding agreement of the Bank enforceable

                                       13
<PAGE>
 
     against the Bank in accordance with its terms, subject, as to
     enforceability to (A) the effect of bankruptcy, insolvency, moratorium,
     receivership, reorganization, liquidation and other similar laws relating
     to or affecting the rights and remedies of creditors generally, and (B) the
     application of principles of equity (regardless of whether considered and
     applied in a proceeding in equity or at law) and the rights and powers of
     the FDIC;

                   (v)   The Trust is not now, and immediately following the 
     sale of the Certificates pursuant to the Underwriting Agreement will not
     be, required to register under the 1940 Act;

                   (vi)  No consent, approval, authorization or order of any 
     governmental agency or body is required for (A) the execution, delivery
     and performance by the Bank of its obligations under the Agreements or the
     Certificates, or (B) the issuance or sale of the Certificates, except such
     as have been obtained under the Act and as may be required under state
     securities or blue sky laws in connection with the purchase and
     distribution of the Certificates by the Underwriters and the filing of
     Uniform Commercial Code financing statements with respect to the
     Receivables and the approval of the Office of the State Bank Commissioner
     of the State of Delaware;

                   (vii) To the best knowledge of such counsel, neither the 
     execution and delivery of the Agreements or the Certificates by the Bank
     nor the performance by the Bank of the transactions therein contemplated
     nor the fulfillment of the terms thereof does or will result in any
     violation of any statute or regulation or any order or decree of any court
     or governmental authority binding upon the Bank or its property, or
     conflict with, or result in a breach or violation of any term or provision
     of, or result in a default under any of the terms and provisions of, the
     Bank's charter or by-laws or any material

                                       14
<PAGE>
 
          indenture, loan agreement or other material agreement to which the
          Bank is a party or by which the Bank is bound;

                   (viii) To the knowledge of such counsel after due
          investigation, there are no legal or governmental proceedings pending
          to which the Bank is a party or to which the Bank is subject which,
          individually or in the aggregate (A) would have a material adverse
          effect on the ability of the Bank to perform its obligations under the
          Agreements or the Certificates, (B) assert the invalidity of the
          Agreements or the Certificates, (C) seek to prevent the issuance, sale
          or delivery of the Certificates or any of the transactions
          contemplated by the Agreements or (D) seek to affect adversely the
          federal income tax or ERISA attributes of the Certificates described
          in the Prospectus;

                   (ix)   The Registration Statement and the Prospectus (except
          for the financial statements, financial schedules and other financial
          and operating data included therein, as to which such counsel
          expresses no view) comply as to form with the Act and the Rules and
          Regulations;

                   (x)    The Registration Statement has become effective under
          the Act, and the Prospectus Supplement will be filed with the
          Commission pursuant to Rule 424(b) thereunder; and

                   (xi)   Such counsel has not independently verified and is not
          passing upon, and does not assume any responsibility for, the
          accuracy, completeness or fairness of the information contained in the
          Registration Statement and Prospectus. Based upon discussion with the
          Bank, its accountants and others, however, no facts have come to its
          attention that cause it to believe that the Prospectus (except for the
          financial statements, financial schedules and other financial and
          statistical data included therein, as to which such counsel expresses
          no view), contains any untrue statement of a

                                       15
<PAGE>
 
     material fact or omits to state a material fact required to be stated
     therein or necessary in order to make the statements therein not
     misleading.

          (f) The Representative shall have received a letter from Skadden,
Arps, Slate, Meagher & Flom LLP, special counsel for the Bank, to the effect

          (g) The Representative shall have received an opinion of Skadden,
Arps, Slate, Meagher & Flom LLP, special counsel to the Bank, addressed to the
Representative, dated the Closing Date and satisfactory in form and substance to
the Representative and its counsel, to the effect that the Certificates will be

          (h) The Representative shall have received from Skadden, Arps, Slate,
Meagher & Flom LLP, counsel for the Underwriters, such opinion or opinions,
dated the Closing Date, substantially to the effect that:

               (i) Each of the Pooling and Servicing Agreement and the CIA
     Agreement (collectively referred to in this subsection (h) as the
     "Agreements") constitutes the valid and binding obligation of the Bank,
     -----------                                                            
     enforceable against the Bank in accordance with its terms, except (x) to
     the extent that the enforceability thereof may be limited by (a)
     bankruptcy, insolvency, receivership, reorganization, moratorium or other
     similar laws now or hereafter in effect relating to creditors' rights
     generally and the rights of creditors of Delaware chartered banks as the
     same may be applied in the event of the bankruptcy, insolvency,
     receivership, reorganization, moratorium or other similar event in respect
     of the Bank, (b) general principles of

                                       16
<PAGE>
 
     equity (regardless of whether enforceability is considered in a proceeding
     at law or in equity) and (c) the qualification that certain of the remedial
     provisions of the Agreements may be unenforceable in whole or in part, but
     the inclusion of such provisions does not affect the validity of the
     Agreements taken as a whole, and the Agreements, together with applicable
     law, contain adequate provisions for the practical realization of the
     benefits of the security created thereby and (y) such counsel expresses no
     opinion as to the enforceability of any rights to contribution or
     indemnification which are violative of public policy underlying any law,
     rule or regulation;

               (ii) The Certificates, when executed and authenticated in
     accordance with the terms of the Pooling and Servicing Agreement and
     delivered to and paid for by the Underwriters pursuant to this Agreement,
     will be duly and validly issued and outstanding and will be entitled to the
     benefits of the Pooling and Servicing Agreement;

               (iii) This Agreement has been duly authorized, executed and
     delivered by the Bank;

               (iv) Neither the execution, delivery or performance by the Bank
     of the Agreements or this Agreement, nor the compliance by the Bank with
     the terms and provisions thereof or hereof, will contravene any provision
     of any applicable law;

               (v)  Based on such counsel's review of applicable laws, no
     governmental approval, which has not been obtained or taken and is not in
     full force and effect, is required to authorize or is required in
     connection with the execution, delivery or performance of the Agreements by
     the Bank;

               (vi) The Certificates, the Agreements and this Agreement conform
     in all material respects to the descriptions thereof contained in the
     Prospectus;

                                       17
<PAGE>
 
               (vii) The Pooling and Servicing Agreement is not required to be
     qualified under the Trust Indenture Act of 1939, as amended, and the Trust
     is not required to be registered under the 1940 Act;
 
               (viii) The statements in the Prospectus under the heading
     "Certain Legal Aspects of the Receivables", to the extent that they
     constitute matters of law or legal conclusions with respect thereto, have
     been reviewed by such counsel and are correct in all material respects; and

               (ix) Each of the Registration Statement, as of its effective
     date, and the Prospectus, as of its date, appeared on its face to be
     appropriately responsive in all material respects to the requirements of
     the Act and the General Rules and Regulations under the Act, except that in
     each case such counsel expresses no opinion as to the financial data
     included therein or excluded therefrom or the exhibits to the Registration
     Statement, and such counsel does not assume any responsibility for the
     accuracy, completeness or fairness of the statements contained in the
     Registration Statement and the Prospectus.

          Such opinion shall also state that such counsel has participated in
conferences with officers and representatives of the Bank, counsel for the Bank,
representatives of the independent accountants of the Bank and the Underwriters
at which the contents of the Prospectus and related matters were discussed and,
although such counsel need not pass upon, and need not assume any responsibility
for, the accuracy, completeness or fairness of the statements contained in the
Prospectus and shall have made no independent check or verification thereof,
except for those made under the caption "Certain Legal Aspects of the
Receivables" to the extent set forth in paragraph (viii) above, on the basis of
the foregoing, no facts shall have come to such counsel's attention that shall
have led such counsel to believe that the Prospectus, as of its date, contained
an untrue statement of a material fact or omitted to state a material fact
necessary in order to make the statements therein, in light of the circumstances
under

                                       18
<PAGE>
 
which they were made, not misleading, except that such counsel need not express
an opinion or belief with respect to the financial statements, schedules and
other financial information included in such Prospectus or excluded therefrom.

New York, a New York banking corporation ("BONY"), in connection with the Agency

Agreement dated as of December 4, 1995 between BONY and the Trustee (the "Agency
                                                                          ------

- ---------                                                            
Representative their written opinion, addressed to the Representative and dated
the Closing Date, in form and substance satisfactory to the Representative and
its counsel, substantially to the effect that:

               (i)  BONY is a banking corporation duly organized, validly
     existing and in good standing under the laws of the State of New York and
     has the corporate power and authority to execute, deliver and perform its
     obligations under the Agency Agreement;

               (ii) the Certificates have been duly authenticated by BONY
     pursuant to the Agency Agreement and in accordance with the Pooling and
     Servicing Agreement;

               (iii) the Trustee is a banking corporation duly organized,
     validly existing and in good standing under the laws of the State of
     Delaware and has the corporate power and authority to execute, deliver and
     perform its obligations under the Pooling and Servicing Agreement and the
     CIA Agreement;

               (iv) the Supplement and the CIA Agreement have been duly
     authorized, executed and delivered by the Trustee, and the Pooling and
     Servicing Agreement and the CIA Agreement constitute the legal, valid and
     binding agreements of the Trustee enforceable against the Trustee in
     accordance with their respective terms, except (x) as may be limited by
     bankruptcy, insolvency, reorganization, moratorium or other similar laws
     relating to or affecting the rights of creditors generally (as such laws
     would apply in the event of the

                                       19
<PAGE>
 
     insolvency, receivership, conservatorship or reorganization of, or other
     similar occurrence with respect to, the Trustee), (y) that the
     enforceability of the Pooling and Servicing Agreement and the CIA Agreement
     may be subject to the application of general principles of equity
     (regardless of whether considered or applied in a proceeding in equity or
     at law), and (z) that certain remedial provisions of the Pooling and
     Servicing Agreement may be unenforceable in whole or in part, but the
     inclusion of such provisions does not affect the validity of the Pooling
     and Servicing Agreement taken as a whole, and the Pooling and Servicing
     Agreement, together with applicable law, contains adequate provisions for
     the practical realization of the benefits of the security provided thereby.
     Such counsel expresses no opinion as to the enforceability of any rights to
     contribution or indemnification that are violative of public policy
     underlying any law, rule or regulation;

               (v) the execution and delivery by the Trustee of the Supplement
     and the CIA Agreement and the performance by the Trustee of its obligations
     under the Pooling and Servicing Agreement and the CIA Agreement do not
     conflict with or result in a violation of (x) any law or regulation of the
     United States of America or the State of Delaware governing the banking or
     trust activities of the Trustee or (y) the amended and restated articles of
     association or by-laws of the Trustee; and

               (vi) the execution and delivery by the Trustee of the Supplement
     and the CIA Agreement and the performance by the Trustee of its obligations
     under the Pooling and Servicing Agreement and the CIA Agreement do not
     require any approval, authorization or other action by, or filing with, any
     governmental authority of the United States of America or the State of
     Delaware having jurisdiction over the banking or trust activities of the
     Trustee, except such as have been obtained, taken or made.

          (j) The Representative shall have received evidence satisfactory to
the Representative and its counsel that, on or before the Closing Date, UCC-1
financing statements have been filed in the appropriate filing offices of the
State of Delaware and such other jurisdictions as counsel to the Bank deems
appropriate to reflect the interest of the Trustee in the Receivables.

          (k) The Class A Certificates shall be rated "AAA" by Standard & Poor's

Standard & Poor's and rated at least "A2" by Moody's on the Closing Date, and

form and substance to the Representative and its counsel, and the Representative
and its counsel shall have received such information, certificates and documents
as any of them may reasonably request.

          7.   Indemnification and Contribution.
               -------------------------------- 

               (a) The Bank agrees to indemnify and hold harmless each 
Underwriter and each person, if any, who controls any 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 are based upon any untrue statement
or alleged untrue statement of any 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

                                       21
<PAGE>
 
statements therein not misleading, 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,
liability or action as such expenses are incurred; provided, however, that the
                                                   --------  -------          
Bank will not 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
by any Underwriter specifically for use therein or any revision or amendment
thereof or supplement thereto.  The foregoing indemnification with respect to
any untrue statement or omission in any preliminary prospectus or prospectus
supplement shall not inure to the benefit of any Underwriter from whom the
person asserting any such losses, claims, damages or liabilities purchased
Certificates, or any person controlling such Underwriter, if a copy of the
Prospectus (as then amended or supplemented if the Bank 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 Certificates 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 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 the Bank's officers who signed
the Registration Statement and each person, if any, who controls the Bank 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 statement
or alleged untrue statement of any 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 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

                                       22
<PAGE>
 
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 by such Underwriter specifically for
use therein 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) Promptly after receipt by an indemnified party under this Section
7 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 this Section
7, notify the indemnifying party in writing of the commencement thereof; but the
omission so to notify the indemnifying party will not relieve the indemnifying
party from any liability which it may have to any indemnified party other than
under this Section 7.  In the event that any such action is brought against any
indemnified party and it notified the indemnifying party of the commencement
thereof, the indemnifying party will be entitled to participate therein and, to
the extent that it may elect by written notice delivered to the indemnified
party promptly after receiving the aforesaid notice from such indemnified party,
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 7 for any legal or other expenses subsequently incurred
by such indemnified party in connection with the defense thereof other than
reasonable costs of investigation. No indemnifying party shall, without the
prior written consent of the indemnified party, effect any settlement of any
pending or threatened proceeding 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 includes an unconditional release
of such indemnified party from all liability on claims that are the subject
matter of such proceeding.

                                       23
<PAGE>
 
          (d) If the indemnification provided for in this Section 7 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 indemnifying 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 Bank on the one hand and the respective Underwriter on the other from the
offering of the Certificates 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 Bank on the one hand and of the respective
Underwriter 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 Bank
on the one hand and the respective Underwriter 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 Bank bear to the total underwriting
discounts and commissions received by such Underwriter.  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 Bank or by any
Underwriter 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), each Underwriter shall not be required to
contribute any amount in excess of the underwriting discount or commission
applicable to the Certificates purchased by it hereunder.  The Bank and the
Underwriters agree that it would not be just and equitable if contribution
pursuant to this subsection (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 any of the

                                       24
<PAGE>
 
equitable considerations referred to above in this subsection (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.

          8.   Survival.  The Bank and the Underwriters agree that the
               --------                                               
respective representations, warranties and agreements made by them herein and in
any certificate or other instrument delivered pursuant hereto shall be deemed
to be relied upon, in the case of the Bank, by each Underwriter and, in the case
of the Underwriters, by the Bank, notwithstanding any investigation heretofore
or hereafter made by or on behalf of the Bank or the Underwriters, and that the
respective representations, warranties and agreements (including without
limitation the indemnity and contribution agreement) made by the Bank and the
Underwriters herein or in any such certificate or other instrument shall survive
the delivery of and payment for the Certificates.

          9.   Termination.   This Agreement may be terminated in the sole
               -----------                                                
discretion of the Underwriters by notice to the Bank given at or prior to the
Closing Date in the event that the Bank shall have failed, refused or been
unable to perform all obligations and satisfy all conditions on its part to be
performed or satisfied hereunder at or prior thereto.  Termination of this
Agreement pursuant to this Section 9 shall be without liability of any party to
any other party except as provided in Sections 5 and 7 hereof.

          10.  Default by One or More of the Underwriters.  If one or more of
               ------------------------------------------                    
the Underwriters shall fail on the Closing Date to purchase the Certificates
which it or they are obligated to purchase under this Agreement (the "Defaulted
                                                                      ---------
Securities"), the lead Underwriter shall have the right, within 24 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, the Representative shall not have completed
such arrangements within such 24-hour period, then:

     (a) if the aggregate amount of Defaulted Securities does not exceed 10% of
     the aggregate principal

                                       25
<PAGE>
 
     amount of the applicable class of Certificates, each of the non-defaulting
     Underwriters of such class of Certificates shall be obligated to purchase
     the full amount thereof in the proportions that their respective
     underwriting obligations hereunder with respect to such class of
     Certificates bear to the underwriting obligations of all non-defaulting
     Underwriters of such class of Certificates, or

     (b) if the aggregate amount of Defaulted Securities exceeds 10% of the
     aggregate principal amount of the applicable class of Certificates, this
     Agreement shall terminate without liability on the part of any non-
     defaulting Underwriter.

     No action taken pursuant to this section shall relieve any defaulting
Underwriter from liability in respect of its default.

     In the event of any such default which does not result in a termination of
this Agreement, either the 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.

          11.  Representation of the Underwriters.  Each of the Underwriters
               ----------------------------------                           
represents and warrants to, and agrees with, the Bank that (w) it has only

Kingdom the scheme described in the

Financial Services Act 1986 or in Regulation 1.04 of the Financial Services
(Promotion of Unregulated Schemes) Regulations 1991.

               ------------------------------------------                   
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 Certificates, transfer, deposit or otherwise convey any Certificates into
a trust or other type of special purpose vehicle that issues securities or other
instruments backed in whole or in part by, or that represents interests in, such

                        -------------------- 

               (a)  On each Distribution Date, the Servicer shall calculate the
Class A Investor Default Amount. If on any Distribution Date, the Class A
Investor Default Amount for such Distribution Date exceeds the sum of the amount
allocated with respect thereto pursuant to subsection 4.09(a)(iii), subsection
4.13(a) and Section 4.14 of the Agreement with respect to the Monthly Period
immediately preceding such Distribution Date, the CIA Invested Amount will be
reduced by the amount of such excess, but not more than the lesser of the Class
A Investor Default Amount and the CIA Invested Amount for such Distribution
Date. In the event that, but for the limitation on the amount of such reduction
in the preceding sentence, such reduction would cause the CIA Invested Amount to
be a negative number, the CIA Invested Amount will be reduced to zero, and the
Class B Invested Amount will be reduced by the amount by which the CIA Invested
Amount would have been reduced below zero. In the event that such reduction
would cause the Class B Invested Amount to be a negative number, the Class B
Invested Amount will be reduced to zero, and the Class A Invested Amount will be
reduced by the amount by which the Class B Invested Amount would have been
reduced below zero, but not more than the Class A Investor Default Amount for
such Distribution Date (a "Class A Investor Charge-Off"). If the Class A
                           ---------------------------                   
Invested Amount has been reduced by the amount of any Class A Investor Charge-
Offs, it will be reimbursed on any Distribution Date (but not by an amount in
excess of the aggregate Class A Investor Charge-Offs) by the amount of Excess
Finance Charge Collections allocated and available for such purpose pursuant to
subsection 4.13(b) of the Agreement.

               (b)  On each Distribution Date, the Servicer shall calculate the
Class B Investor Default

                                      47

Amount. If on any Distribution Date, the Class B Investor Default Amount for
such Distribution Date exceeds the amount of Excess Finance Charge Collections
and Reallocated Principal Collections which are allocated and available to fund
such amount pursuant to subsection 4.13(d) and Section 4.14 of the Agreement,
the CIA Invested Amount (after giving effect to any adjustments with respect
thereto as described in the preceding paragraph) will be reduced by the amount
of such excess but not more than the lesser of the Class B Investor Default
Amount and the CIA Invested Amount for such Distribution Date.  In the event
that, but for the limitation on the amount of such reduction in the preceding
sentence, such reduction would cause the CIA Invested Amount to be a negative
number, the CIA Invested Amount shall be reduced to zero and the Class B
Invested Amount shall be reduced by the amount by which the CIA Invested Amount
would have been reduced below zero, but not more than the Class B Investor
Default Amount for such Distribution Date (a "Class B Investor Charge-Off").
                                              ---------------------------    
The Class B Invested Amount will also be reduced by the amount of Reallocated
Class B Principal Collections in excess of the CIA Invested Amount pursuant to
Section 4.14 of the Agreement and the amount of any portion of the Class B
Invested Amount allocated to the Class A Certificates to avoid a reduction in
the Class A Invested Amount pursuant to subsection 4.12(a) of the Agreement. The
Class B Invested Amount will thereafter be reimbursed (but not by an amount in
excess of the unpaid principal balance of the Class B Certificates) on any
Distribution Date by the amount of Excess Finance Charge Collections allocated
and available for that purpose as described under subsection 4.13(e) of the
Agreement.

               (c)  On each Distribution Date, the Servicer shall calculate the
CIA Investor Default Amount. If on any Distribution Date, the CIA Investor
Default Amount for such Distribution Date exceeds the sum of the amount of
Excess Finance Charge Collections which are allocated and available to fund such
amount pursuant to subsection 4.13(h) of the Agreement and amounts applied with
respect to the CIA Investor Default Amount pursuant to the Exchangeable
Certificate Purchase Agreement (which amounts shall be applied as specified in
subsection 4.13(h) of the Agreement), the CIA Invested Amount (after giving
effect to any adjustments with respect thereto as described in the preceding
paragraphs) will be reduced by the amount of such excess but not more than the
lesser of the CIA Investor Default Amount and the CIA Invested

                                      48

                                      -----------------------            
Invested Amount will also be reduced by the amount of Reallocated Principal
Collections pursuant to Section 4.14 of the Agreement and the amount of any
portion of the CIA Invested Amount allocated to the Class A Certificates or the
Class B Certificates to avoid a reduction in the Class A Invested Amount,
pursuant to subsection 4.12(a) of the Agreement, or the Class B Invested Amount,
pursuant to subsection 4.12(b) of the Agreement, respectively. The CIA Invested
Amount will thereafter be reimbursed (but not by an amount in excess of the
unpaid principal balance of the CIA Certificates) on any Distribution Date by
the amount of Excess Finance Charge Collections allocated and available for that
purpose as described under subsection 4.13(i) of the Agreement.

transferred to the Trust on such day) and on Transfer Dates with respect to the
Amortization Period, will be deposited in the Principal Account and treated as a
portion of Available Investor Principal Collections for the related Distribution
Date;

               (c)  an amount equal to the amount of interest which has accrued

          (e) an amount equal to the aggregate amount by which the Class B
Invested Amount has been reduced below the initial Class B Invested Amount for
reasons other than the payment of principal to the Class B Certificateholders
(but not in excess of the aggregate amount of such reductions which have not
been previously reimbursed) will be distributed to the holder of the
Exchangeable Transferor Certificate on Transfer Dates with respect to the
Revolving Period, but not in an amount exceeding the Transferor Interest in
Principal Receivables on such day (after giving effect to any new Principal

equal to the product of (a)(i) during the Revolving Period, the CIA Floating
Allocation Percentage or (ii) during an Amortization Period, the CIA

     Agreement; and

     (and therefore not constituting Reallocated CIA Principal Collections)
     will, on Distribution Dates with respect to the Revolving Period, be
     applied as Available Investor Principal Collections.

cause the Trustee to apply an amount, not to exceed the Class B Invested Amount,
equal to the product of (a)(i) during the Revolving Period, the Class B Floating
Allocation Percentage or (ii) during an Amortization Period, the Class B

          On each Distribution Date the CIA Invested Amount shall be reduced by
the amount of Reallocated CIA Principal Collections and by the amount of
Reallocated Class B Principal Collections for such Distribution Date.  In the
event that such reduction would cause the CIA Invested Amount to be a negative
number, the CIA Invested Amount shall be reduced to zero and the Class B
Invested Amount shall be reduced by the amount by which the CIA Invested Amount
would have been reduced below zero.  In the event that the reallocation of

such Distribution Date in an aggregate amount not to exceed the amount which
would cause the Class B Invested Amount to be reduced to zero.

LIBOR on the basis of the rate for deposits in United States dollars for a
period equal to the relevant Interest Period which appears on Telerate Page 3750

Telerate Page 3750, 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 period equal to the

(the "Principal Funding Account"), bearing a designation clearly indicating
      -------------------------

Account ceases to be a Qualified Institution the Transferor shall notify the
Trustee, and the Trustee upon being notified (or the Servicer on its behalf)
shall, within ten (10) Business Days, establish a new Principal Funding Account
meeting the conditions specified above with a Qualified Institution, and shall

The Trustee, at the written direction of the Servicer, shall (i) make

               (a) The Servicer shall establish and maintain with a Qualified
Institution, which may be the Trustee, in the name of the Trustee, on behalf of
the Trust, for the benefit of the Investor Certificateholders, a segregated
trust account with the corporate trust department of such Qualified Institution
(the "Reserve Account"), bearing a designation clearly indicating that the funds
      ---------------

The Trustee shall possess all right, title and interest in all funds on deposit
from time to time in the Reserve Account and in all proceeds thereof.  The
Reserve Account shall be under the sole dominion and control of the Trustee for

holding the Reserve Account ceases to be a Qualified Institution the Transferor
shall notify the Trustee, and the Trustee upon being notified (or the Servicer
on its behalf) shall, within 10 Business Days, establish a new Reserve Account
meeting the conditions specified above with a Qualified Institution, and shall
transfer any cash or any investments to such new Reserve Account.  The Trustee,
at the written direction of the Servicer, shall (i) make withdrawals from the
Reserve Account from time to time in an amount up to the Available Reserve
Account Amount at such time, for the purposes set forth in this Supplement, and
(ii) on each Transfer Date (from and after the Reserve Account Funding Date)

                                      56

available for withdrawal on or prior to the following Transfer Date.  The
Trustee shall maintain for the benefit of the Investor Certificateholders
possession of the negotiable instruments or securities, if any, evidencing such
Permitted Investments.  No Permitted Investment shall be disposed of prior to
its maturity.  On each Transfer Date, all interest and earnings (net of losses
and investment expenses) accrued since the preceding Transfer Date on funds on
deposit in the Reserve Account shall be retained in the Reserve Account (to the
extent that the Available Reserve Account Amount is less than the Required
Reserve Account Amount) and the balance, if any, shall be deposited into the
Finance Charge Account for application as Collections of Finance Charge 
Receivables allocable to the Investor Certificates on such Transfer Date.  For
purposes of determining the availability of funds or the balance in the Reserve
Account for any reason under this Supplement, except as otherwise provided in
the preceding sentence, investment earnings on such funds shall be deemed not to
be available or on deposit.

               (c) On each Transfer Date with respect to the Accumulation Period
prior to the payment in full of the Invested Amount and the first Transfer Date
with respect to the Rapid Amortization Period, the Servicer shall calculate the
"Reserve Draw Amount" which shall be equal to the Principal Funding Investment

otherwise would be available for deposit in the Reserve Account under subsection
4.13(j) of the Agreement with respect to such Transfer Date.

               (d) In the event that for any Transfer Date the Reserve Draw
Amount is greater than zero, the Reserve Draw Amount, up to the Available
Reserve Account Amount, shall be withdrawn from the Reserve Account on such
Transfer Date by the Trustee (acting in accordance with the written instructions
of the Servicer), deposited into the Finance Charge Account for application in
accordance with Section 4.09 of the Agreement.

               (e) In the event that the Reserve Account Surplus on any Transfer
Date, after giving effect to all deposits to and withdrawals from the Reserve
Account with respect to such Transfer Date, is greater



                                      57

the Servicer, shall withdraw from the Reserve Account and deposit in the Finance
Charge Account an amount equal to such Reserve Account Surplus for application

            FIRST USA CREDIT CARD MASTER TRUST CLASS A FLOATING RATE
                    ASSET BACKED CERTIFICATE, SERIES 1997-10

Evidencing an undivided interest in a trust, the corpus of which consists of
receivables generated from time to time in the ordinary course of business in a
portfolio of VISA(R) and MasterCard(R)* credit card accounts generated
or to be generated by First USA Bank (the "Bank").

                 (Not an interest in or a recourse obligation
                 of First USA Bank or any affiliate thereof)

          This certifies that CEDE & CO. (the "Certificateholder") is the
registered owner of a fractional undivided interest in the First USA Credit Card
Master Trust (the "Trust") issued pursuant to the Pooling and Servicing 
Agreement, dated as of September 1, 1992 between the Bank, as Transferor (the
"Transferor") and as Servicer (the "Servicer"), and The Bank of New York
(Delaware), as trustee (the "Trustee") of the Trust (the "Agreement"; such term
to include any Supplement or amendment thereto) as supplemented by the Series

     Incorporated and MasterCard International Incorporated, respectively.
<PAGE>
 
plement"), dated as of December 23, 1997, between the Bank, as Transferor and
Servicer, and the Trustee.  The corpus of the Trust consists of all of the
Transferor's right, title and interest in a portfolio of receivables (the
"Receivables") existing in certain VISA/(R)/ and MasterCard/(R)/ revolving 
credit card accounts identified in the Agreement from time to time (the
"Accounts"), all Receivables generated under the Accounts from time to time
thereafter, all monies due or to become due and all amounts received with
respect to the Receivables in existence in the Accounts, all monies on deposit
in certain bank accounts (excluding any investment earnings on such deposited
amounts except as set forth in the Series 1997-10 Supplement), and all other
assets and interests constituting the Trust and all proceeds of the foregoing.

          Although a summary of certain provisions of the Agreement is set forth
below, this Class A Certificate does not purport to summarize the Agreement and
reference is made to the Agreement for information with respect to the
interests, rights, benefits, obligations, proceeds, and duties evidenced hereby
and the rights, duties and obligations of the Trustee. A copy of the Agreement
may be requested from the Trustee by writing to the Trustee at The Bank of New
York (Delaware), White Clay Center, Route 273, Newark, Delaware, 19711,
Attention: Bond Administration. To the extent not defined herein, the
capitalized terms used herein have the meanings ascribed to them in the
Agreement. This Certificate is one of a Series of Certificates entitled "First
USA Credit Card Master Trust Class A Floating Rate Asset Backed Certificates,
Series 1997-10" (the "Class A Certificates"), each of which represents a
fractional undivided interest in the Trust, and is issued under and is subject
to the terms, provisions and conditions of the Agreement, to which Agreement, as
amended from time to time, the Certificateholder by virtue of the acceptance
hereof assents and by which the Certificateholder is bound. In the case of any
conflict between terms specified in this Class A Certificate and terms specified
in the Agreement, the terms of the Agreement shall govern.

          The Transferor has structured the Agreement, the Class A Certificates
and the First USA Credit Card Master Trust Class B Floating Rate Asset Backed
Certificates, Series 1997-10 (the "Class B Certificates") with the intention  
that the Class A Certificates and the Class B Certificates will qualify under
applicable tax law as indebtedness,
<PAGE>
 
and the Transferor and each holder of a Class A Certificate (a "Class A
Certificateholder") or any interest therein, by acceptance of its Class A
Certificate or any interest therein, agrees to treat the Class A Certificates
for purposes of federal, state, local and foreign income or franchise taxes and
any other tax imposed on or measured by income, as indebtedness.

          The Trust's assets are allocated in part to the holders of the Class A
Certificates, the holders of the Class B Certificates and the holders of the
First USA Credit Card Master Trust CIA Certificates, Series 1997-10 (the "CIA
Certificates") (such holders together the "Investor Certificateholders") with
the remainder allocated to holders of other Series of Certificates issued by the
Trust, if any, and to the Transferor.  In addition to the Class A Certificates,
the Class B Certificates and the CIA Certificates, the Exchangeable Transferor
Certificate will be reissued pursuant to the Agreement and will represent the
Transferor's interest in the Trust.  The reissued Exchangeable Transferor
Certificate will represent the interest in the Principal Receivables not
represented by the Class A Certificates, the Class B Certificates and the CIA
Certificates (together the "Investor Certificates") or any other Series of
Certificates.  The Exchangeable Transferor Certificate may be exchanged by the
Transferor pursuant to the Agreement for one or more Series of Certificates and
a reissued Exchangeable Transferor Certificate upon the conditions set forth in
the Agreement.

          The Class A Initial Invested Amount is $700,000,000.  The Class A
Invested Amount for any monthly Distribution Date will be an amount equal to
$700,000,000, minus the aggregate amount of principal payments made to the Class
              -----                                                             
A Certificateholders prior to such Distribution Date and minus the excess, if
                                                         -----               
any, of the aggregate amount of Class A Investor Charge-Offs over the Class A
Investor Charge-Offs reimbursed prior to such date.

          The Class A Certificates will bear interest at the rate of 6.05875%
per annum on the Class A Initial Invested Amount from December 23, 1997 through
January 19, 1998, and for each Interest Period thereafter, the Class A 
Certificates will bear interest at a per annum rate of 0.09% in excess of LIBOR
as determined by the Trustee on the related LIBOR Determination Date (each such
rate as in effect from time to time, the "Class A Certificate Rate"). Interest
will
<PAGE>
 
be distributed to the extent of available funds on January 20, 1998, and on the
seventeenth day of each month thereafter, or if such day is not a Business Day,
the next succeeding Business Day until the earlier of the day on which the
Class A Invested Amount is paid in full and the Scheduled Series 1997-10
Termination Date (each such date a "Distribution Date"), in an amount equal to
the product of (a) the actual number of days in the related Interest Period
divided by 360, (b) the Class A Certificate Rate and (c) the Class A Outstanding
Principal Balance on the last day of the Monthly Period immediately preceding
such Distribution Date.  Interest for a Distribution Date will accrue from and
including the previous Distribution Date (or in the case of the first
Distribution Date, from and including the Closing Date), to, and including, the
day immediately preceding the current Distribution Date.  Interest payments will
be made from Collections of Finance Charge Receivables and certain other
amounts allocated to the Class A Certificates comprising Class A Available Funds
and, in certain circumstances, from Reallocated Principal Collections on January
20, 1998 and on each Distribution Date thereafter until the Scheduled Series
1997-10 Termination Date.  Interest will be payable monthly on each Distribution
Date to the Class A Certificateholders of record as of the related Record Date.
The Record Date with respect to any Distribution Date shall be the last day of
the calendar month preceding such Distribution Date.

          As described in the Agreement, Collections of Principal Receivables
with respect to any Monthly Period will be allocated on the related
Determination Date on the basis of the aggregate Investor Percentage of all
Series and the Transferor Percentage with respect to the Principal Receivables.
Such allocation will be performed both during the Revolving Period and any
Amortization Period.  Throughout the existence of the Trust, the Servicer will
allocate to the Transferor, as holder of the Exchangeable Transferor
Certificate, an amount equal to the Transferor Percentage of the aggregate
amount of Collections of Finance Charge Receivables and Principal Receivables
for each Monthly Period.  During the Revolving Period relating to the Investor
Certificates, the Class B Floating Allocation Percentage of Collections of
Principal Receivables and the CIA Floating Allocation Percentage of Collections
of Principal Receivables will be applied first as Reallocated Principal
Collections, to the extent required, and any remaining amounts together with the
Class A Floating Allocation Percentage of Principal Receivables will be
distributed first to the certificate-
<PAGE>
 
holders of other Series to the extent of the amount of Principal Shortfalls, if
any, and then to the Transferor in an amount not to exceed the amount of the
Transferor Interest.

          Unless a Pay Out Event has occurred, the Accumulation Period will
begin at the close of business on the last day of the Revolving Period and will
end on the earlier of (i) the commencement of the Rapid Amortization Period,
(ii) payment of the Invested Amount in full and (iii) the Scheduled Series
1997-10 Termination Date.  On each Transfer Date following the commencement of
the Accumulation Period, prior to the earlier of the payment of the Class A
Invested Amount in full and the commencement of the Rapid Amortization Period,
the Trustee will deposit in the Principal Funding Account an amount equal to the
least of (a) Available Investor Principal Collections with respect to the
preceding Monthly Period, (b) the applicable Controlled Deposit Amount and (c)
the Class A Adjusted Invested Amount prior to any such deposit on such day.
Amounts in the Principal Funding Account will be paid to the Class A
Certificateholders on the Class A Scheduled Payment Date.  After the full amount
of the Class A Invested Amount has been deposited in the Principal Funding
Account and beginning with the Transfer Date related to the Class B Principal
Commencement Date, prior to the commencement of the Rapid Amortization Period,
the Trustee will deposit in the Principal Funding Account an amount equal to the
least of (a) the Available Investor Principal Collections with respect to the
preceding Monthly Period remaining after application thereof to the Class A
Invested Amount, (b) the applicable Controlled Deposit Amount (minus the Class A
Monthly Principal with respect to such Transfer Date) and (c) the Class B
Adjusted Invested Amount prior to any such deposit on such day.  After payment
in full of the Class A Invested Amount, amounts in the Principal Funding Account
will be paid to the Class B Certificateholders on the Class B Scheduled Payment
Date.  After the full amount of the sum of the Class A Invested Amount and the
Class B Invested Amount has been deposited in the Principal Funding Account,
prior to the commencement of the Rapid Amortization Period, the Trustee will
deposit in the Principal Funding Account an amount equal to the least of (a) the
Available Investor Principal Collections with respect to the preceding Monthly
Period remaining after application thereof to the Class A Invested Amount and
the Class B Invested Amount, (b) the applicable Controlled Deposit Amount (minus
the Class A Monthly Principal and the Class B Monthly Principal with respect to
such Transfer
<PAGE>
 
Date) and (c) the CIA Adjusted Invested Amount prior to any such deposit on such
day.  After payment in full of the Class A Invested Amount and the Class B
Invested Amount, amounts in the Principal Funding Account will be paid to the
CIA Certificateholders on the CIA Scheduled Payment Date.  During the
Accumulation Period, the portion of Available Investor Principal Collections not
applied to Class A Monthly Principal, Class B Monthly Principal or CIA Monthly
Principal on a Transfer Date will generally be treated as Excess Principal
Collections.

          Upon written notice to the Trustee and satisfaction of certain
conditions, the Servicer may elect to postpone the commencement of the
Accumulation Period, and extend the length of the Revolving Period.

          Unless the Rapid Amortization Period has begun, funds on deposit in
the Principal Funding Account will be distributed to the Class A
Certificateholders on the January 2001 Distribution Date (the "Class A Scheduled
Payment Date").  If the aggregate principal amount of deposits made to the
Principal Funding Account are insufficient to pay in full the Class A Invested
Amount on the Class A Scheduled Payment Date the Rapid Amortization Period will
commence and on each Distribution Date thereafter until the Class A Invested
Amount is paid in full, the Class A Certificateholders will receive
distributions of Class A Monthly Principal and Class A Monthly Interest.

          If a Pay Out Event occurs during the Accumulation Period, the Rapid
Amortization Period will commence and any amount on deposit in the Principal
Funding Account will be distributed to the Certificateholders of each Class of
Certificates, sequentially, in order of seniority, on the Distribution Date
following the Monthly Period in which the Rapid Amortization Period commences.

          During the period beginning on the earlier of the day on which a Pay
Out Event occurs and the Class A Scheduled Payment Date if the Invested Amount
is not paid in full on such date, and ending on the earlier of (i) the date on
which the Class A Invested Amount, the Class B Invested Amount and the CIA
Invested Amount have been paid in full and (ii) the Scheduled Series 1997-10

tificate or to the holders of the certificates of any other Series or, if the
Accumulation Period has commenced, deposited in the Principal Funding Account,
but instead will be distributed to the Class A Certificateholders and, following
payment in full of the Class A Invested Amount, to the Class B
Certificateholders, and, following payment in full of the Class B Invested
Amount, to the CIA Certificateholders, monthly on each Distribution Date
beginning with the Distribution Date in the month following the commencement of
the Rapid Amortization Period.

          Subject to the Agreement, payments of principal are limited to the
unpaid Class A Invested Amount of the Class A Certificates, which may be less
than the unpaid balance of the Class A Certificates pursuant to the terms of the
Agreement.  All principal of and interest on the Class A Certificates is due and
payable no later than September 17, 2003 (or if such day is not a Business Day,
the next succeeding Business Day) (the "Scheduled Series 1997-10 Termination
Date").  After the Scheduled Series 1997-10 Termination Date, neither the Trust
nor the Transferor will have any further obligation to distribute principal or
interest on the Class A Certificates.

          The transfer of this Certificate shall be registered in the
Certificate Register upon surrender of this Certificate for registration of
transfer at any office or agency maintained by the Transfer Agent and Registrar
accompanied by a written instrument of transfer in a form satisfactory to the
Trustee and the Transfer Agent and Registrar duly executed by the
Certificateholder or such Certificateholder's attorney duly authorized in
writing, and thereupon one or more new Class A Certificates of authorized
denominations and for the same aggregate Undivided Interests will be issued to
the designated transferee or transferees.

          As provided in the Agreement and subject to certain limitations
therein set forth, Class A Certificates are exchangeable for new Class A
Certificates evidencing like aggregate Undivided Interests, as requested by the
Class A Certificateholder surrendering such Class A Certificates.  No service
charge may be imposed for any such exchange but the Transferor, Servicer, or
Transfer Agent and Registrar may require payment of a sum sufficient to cover
any tax or other governmental charge that may be imposed in connection
therewith.

          The Transferor, the Servicer, the Trustee, the Paying Agent and the
Transfer Agent and Registrar, and any agent of any of them, may treat the person
in whose name this Certificate is registered as the owner hereof for all
purposes, and neither the Transferor, the Servicer, the Trustee, the Paying
Agent and the Transfer Agent and Registrar, nor any agent of any of them or of
any such agent, shall be affected by notice to the contrary except in certain
circumstances described in the Agreement.

          The Agreement and any Supplement may be amended by the Transferor, the
Servicer and the Trustee, without the consent of certificateholders of any
Series then outstanding for any purpose, provided that (i) the Transferor shall
                                         --------                              
deliver an opinion of counsel acceptable to the Trustee to the effect that such
amendment will not adversely affect in any material respect the interest of such
certificateholders, and (ii) such amendment will not result in a withdrawal or
reduction of the rating of any outstanding Series.

          The Agreement and the Series 1997-10 Supplement may be amended by the
Transferor, the Servicer and the Trustee with the consent of the holders of
certificates evidencing undivided interests aggregating not less than 66-2/3%
of the investor interests of all Series adversely affected, for the purpose of
adding any provisions to, changing in any manner or eliminating any of the
provisions of the Agreement or the Series 1997-10 Supplement or of modifying in
any manner the rights of certificateholders of any then outstanding Series.  No
such amendment, however, may (a) reduce in any manner the amount of, or delay
the timing of, distributions required to be made on any such Series, (b) change
the definition of or the manner of calculating the interest of any
certificateholder of such Series, or (c) reduce the aforesaid percentage of
undivided interests the holders of which are required to consent to any such
amendment, in each case without the consent of all certificateholders of all
Series adversely affected.  Promptly following the execution of any amendment to
the Agreement, the Trustee will furnish written notice of the substance of such
amendment to each Class A Certificateholder.

                  (Not an interest in or a recourse obligation

          This certifies that CEDE & CO. (the "Certificateholder") is the

extent not defined herein, the capitalized terms used herein have the meanings
ascribed to them in the Agreement.  This Certificate is one of a  Series of
Certificates entitled "First USA Credit Card Master Trust Class B Floating Rate
Asset Backed Certificates, Series 1997-10" (the "Class B Certificates"), each of
which represents a fractional undivided interest in the Trust, and is issued
under and is subject to the terms, provisions and conditions of the Agreement,
to which Agreement, as amended from time to time, the Certificateholder by
virtue of the acceptance hereof assents and by which the Certificateholder is
bound.  In the case of any conflict between terms specified in this Class B
Certificate and terms specified in the Agreement, the terms of the Agreement
shall govern.

          The Transferor has structured the Agreement, the Class B Certificates
and the First USA Credit Card Master Trust Class A Floating Rate Asset Backed
Certificates, Series 1997-10 (the "Class A Certificates") with the intention
that the Class A Certificates and the Class B Certificates will qualify under
applicable tax law as indebtedness, and the Transferor and each holder of a
Class B Certificate (a "Class B Certificateholder") or any interest therein, by
acceptance of its Class B Certificate or any interest therein, agrees to treat
the Class B Certificates for purposes of federal, state, local and foreign
income or franchise taxes and any other tax imposed on or measured by income, as
indebtedness.

          The Trust's assets are allocated in part to the holders of the Class A
Certificates, the holders of the Class B Certificates and the holders of the
First USA Credit Card Master Trust CIA Certificates, Series 1997-10 (the "CIA
Certificates") (such holders together the "Investor Certificateholders") with
the remainder allocated to holders of other Series of Certificates issued by the
Trust, if any, and to the Transferor.  In addition to the Class A Certificates,
the Class B Certificates and the CIA Certificates, the Exchangeable Transferor
Certificate will be reissued pursuant to the Agreement and will represent the
Transferor's interest in the Trust.  The reissued Exchangeable Transferor
Certificate will represent the interest in the Principal Receivables not
represented by the Class A Certificates, the Class B Certificates and the CIA
Certificates (together the "Investor Certificates") or any other Series of
Certificates.  The Exchangeable Transferor Certificate may be exchanged by the
Transferor pursuant to the

                                      B-3
<PAGE>
 
Agreement for one or more Series of Certificates and a reissued Exchangeable
Transferor Certificate upon the conditions set forth in the Agreement.

          The Class B Initial Invested Amount is $63,253,000.  The Class B
Invested Amount for any monthly Distribution Date will be an amount equal to (i)
$63,253,000, minus (ii) the aggregate amount of principal payments made to the
             -----                                                            
Class B Certificateholders prior to such Distribution Date, minus (iii) the
                                                            -----          
aggregate amount of Class B Investor Charge-Offs for all prior Distribution
Dates, minus (iv) the aggregate amount of Reallocated Class B Principal
       -----                                                           
Collections for which the CIA Invested Amount has not been reduced for all prior
Distribution Dates, minus (v) an amount equal to the aggregate amount by which
                    -----                                                     
the Class B Invested Amount has been reduced to fund the Class A Investor
Default Amount on all prior Distribution Dates as described in the Agreement and
                                                                                
plus (vi) the aggregate amount of Excess Finance Charge Collections and certain
- ----                                                                           
other amounts allocated and available for purposes of reimbursing amounts
deducted pursuant to clauses (iii), (iv) and (v).

          The Class B Certificates will bear interest at the rate of 6.23875%
per annum on the Class B Initial Invested Amount from December 23, 1997 through
January 19, 1998 and for each Interest Period thereafter, the Class B 
Certificates will bear interest at a per annum rate of 0.27% in excess of 
LIBOR as determined by the Trustee on the related LIBOR Determination Date 
(each such rate as in effect from time to time, the "Class B Certificate Rate").
Interest will be distributed to the extent of available funds on January 20,
1998, and on the seventeenth day of each month thereafter, or if such day is not
a Business Day, the next succeeing Business Day until the earlier of the day on
which the Class B Invested Amount is paid in full and the Scheduled Series 1997-
10 Termination Date (each such date a "Distribution Date"), in an amount equal
to the product of (a) the actual number of days in the related Interest Period
divided by 360, (b) the Class B Certificate Rate and (c) the Class B Outstanding
Principal Balance on the last day of the Monthly Period immediately preceding
such Distribution Date. Interest for a Distribution Date will accrue from and
including the previous Distribution Date (or in the case of the first
Distribution Date, from and including the Closing Date), to, and including, the
day immediately preceding the current Distribution Date. Interest payments will
be made from Col-
 
                                      B-4
<PAGE>
 
lections of Finance Charge Receivables and, in certain circumstances, from
Reallocated Principal Collections on January 20, 1998 and on each Distribution
Date thereafter until the Scheduled Series 1997-10 Termination Date. Interest
will be payable monthly on each Distribution Date to the Class B
Certificateholders of record as of the related Record Date.  The Record Date
with respect to any Distribution Date shall be the last day of the calendar
month preceding such Distribution Date.

          As described in the Agreement, Collections of Principal Receivables
with respect to any Monthly Period will be allocated on the related
Determination Date on the basis of the aggregate Investor Percentage of all
Series and the Transferor Percentage with respect to the Principal Receivables.
Such allocation will be performed both during the Revolving Period and any
Amortization Period.  Throughout the existence of the Trust, the Servicer will
allocate to the Transferor, as holder of the Exchangeable Transferor
Certificate, an amount equal to the Transferor Percentage of the aggregate
amount of Collections of Finance Charge Receivables and Principal Receivables
for each Monthly Period.  During the Revolving Period relating to the Investor
Certificates, the Class B Floating Allocation Percentage of Collections of
Principal Receivables and the CIA Floating Allocation Percentage of Collections
of Principal Receivables will be applied first as Reallocated Principal
Collections, to the extent required, and any remaining amounts together with the
Class A Floating Allocation Percentage of Principal Receivables will be
distributed first to the certificateholders of other Series to the extent of
the amount of Principal Shortfalls, if any, and then to the Transferor in an
amount not to exceed the amount of the Transferor Interest.

          Unless a Pay Out Event has occurred, the Accumulation Period will
begin at the close of business on the last day of the Revolving Period and will
end on the earlier of (i) the commencement of the Rapid Amortization Period,
(ii) payment of the Invested Amount in full and (iii) the Scheduled Series
1997-10 Termination Date.  On each Transfer Date following the commencement of
the Accumulation Period, prior to the earlier of the payment of the Class A
Invested Amount in full and the commencement of the Rapid Amortization Period,
the Trustee will deposit in the Principal Funding Account an amount equal to the
least of (a) Available Investor Principal Collections with respect to the
preceding

                                      B-5
<PAGE>
 
Monthly Period, (b) the applicable Controlled Deposit Amount and (c) the Class A
Adjusted Invested Amount prior to any such deposit on such day.  Amounts in the
Principal Funding Account will be paid to the Class A Certificateholders on the
Class A Scheduled Payment Date.  After the full amount of the Class A Invested
Amount has been deposited in the Principal Funding Account and beginning with
the Transfer Date related to the Class B Principal Commencement Date, prior to
the commencement of the Rapid Amortization Period, the Trustee will deposit in
the Principal Funding Account an amount equal to the least of (a) the Available
Investor Principal Collections with respect to the preceding Monthly Period
remaining after application thereof to the Class A Invested Amount, (b) the
applicable Controlled Deposit Amount (minus the Class A Monthly Principal with
respect to such Transfer Date) and (c) the Class B Adjusted Invested Amount
prior to any such deposit on such day.  After payment in full of the Class A
Invested Amount, amounts in the Principal Funding Account will be paid to the
Class B Certificateholders on the Class B Scheduled Payment Date.  After the
full amount of the sum of the Class A Invested Amount and the Class B Invested
Amount has been deposited in the Principal Funding Account, prior to the
commencement of the Rapid Amortization Period, the Trustee will deposit in the
Principal Funding Account an amount equal to the least of (a) the Available
Investor Principal Collections with respect to the preceding Monthly Period
remaining after application thereof to the Class A Invested Amount and the Class
B Invested Amount, (b) the applicable Controlled Deposit Amount (minus the Class
A Monthly Principal and the Class B Monthly Principal with respect to such
Transfer Date) and (c) the CIA Adjusted Invested Amount prior to any such
deposit on such day.  After payment in full of the Class A Invested Amount and
the Class B Invested Amount, amounts in the Principal Funding Account will be
paid to the CIA Certificateholders on the CIA Scheduled Payment Date.  During
the Accumulation Period, the portion of Available Investor Principal Collections
not applied to Class A Monthly Principal, Class B Monthly Principal or CIA
Monthly Principal on a Transfer Date will generally be treated as Excess
Principal Collections.

          Upon written notice to the Trustee and satisfaction of certain
conditions, the Servicer may elect to postpone the commencement of the
Accumulation Period, and extend the length of the Revolving Period.

                                      B-6
<PAGE>
 
          On the January 2001 Distribution Date if the Class A Invested Amount
is paid in full, Available Investor Principal Collections and Excess Principal
Collections allocable to Series 1997-10 will be used to pay the Class B Invested
Amount as described in the Agreement.  If the Available Investor Principal
Collections and Excess Principal Collections allocable to Series 1997-10 are
insufficient to pay in full the Class B Invested Amount on the January 2001
Distribution Date, the Rapid Amortization Period will commence.

          If a Pay Out Event occurs during the Accumulation Period, the Rapid
Amortization Period will commence and any amount on deposit in the Principal
Funding Account will be distributed to the Certificateholders of each Class of
Certificates, sequentially, in order of seniority, on the Distribution Date
following the Monthly Period in which the Rapid Amortization Period commences.

          During the period beginning on the earlier of the day on which a Pay
Out Event occurs and the Class A Scheduled Payment Date if the Invested Amount
is not paid in full on such date, and ending on the earlier of (i) the date on
which the Class A Invested Amount, the Class B Invested Amount and the CIA
Invested Amount have been paid in full and (ii) the Scheduled Series 1997-10
Termination Date (the "Rapid Amortization Period"), collections of Principal
Receivables allocated to the Invested Amount will no longer be paid to the
holder of the Exchangeable Transferor Certificate or to the holders of the
certificates of any other Series or, if the Accumulation Period has commenced,
deposited in the Principal Funding Account, but instead will be distributed to
the Class A Certificateholders and, following payment in full of the Class A
Invested Amount, to the Class B Certificateholders, and, following payment in
full of the Class B Invested Amount, to the CIA Certificateholders, monthly on
each Distribution Date beginning with the Distribution Date in the month
following the commencement of the Rapid Amortization Period.

          Principal payments on the Class B Certificates will be, during the
Accumulation Period, funded by deposits to the Principal Funding Account or,
during the Rapid Amortization Period, made monthly, and will commence on the
date (the "Class B Principal Commencement Date") which is (a) with respect to
the Accumulation Period, the first Distribution Date on which an amount equal
to the Class A Invested Amount has been deposited in the Principal Funding
Account

                                      B-7
<PAGE>
 
and allocated to the Class A Certificates or (b) with respect to the Rapid
Amortization Period, the Distribution Date on which the Class A Invested Amount
has been paid in full or, if there are no Principal Receivables allocable to the
Investor Certificates remaining after payments have been made to the Class A
Certificates on such Distribution Date, the Distribution Date following the
Distribution Date on which the Class A Invested Amount has been paid in full.
After payment in full of the Class A Invested Amount, amounts deposited in the
Principal Funding Account for the benefit of the Class B Certificates will be
paid to the Class B Certificateholders on the January 2001 Distribution Date and
on each Distribution Date during the Rapid Amortization Period beginning with
the Class B Principal Commencement Date, and thereafter until the payment in
full of the Class B Invested Amount or the termination of the Trust, the
Percentage Allocation of all collections of Principal Receivables and certain
other amounts for the preceding Monthly Period remaining after payment in full
of the Class A Invested Amount will be distributed to the Class B 
Certificateholders.

          Subject to the Agreement, payments of principal are limited to the
unpaid Class B Invested Amount of the Class B Certificates, which may be less
than the unpaid balance of the Class B Certificates pursuant to the terms of the
Agreement.  All principal of and interest on the Class B Certificates is due and
payable no later than September 17, 2003 (or if such day is not a Business Day,
the next succeeding Business Day) (the "Scheduled Series 1997-10 Termination
Date").  After the Series 1997-10 Termination Date, neither the Trust nor the
Transferor will have any further obligation to distribute principal or interest
on the Class B Certificates.

          The transfer of this Certificate shall be registered in the
Certificate Register upon surrender of this Certificate for registration of
transfer at any office or agency maintained by the Transfer Agent and Registrar
accompanied by a written instrument of transfer in a form satisfactory to the
Trustee and the Transfer Agent and Registrar duly executed by the
Certificateholder or such Certificateholder's attorney duly authorized in
writing, and thereupon one or more new Class B Certificates of authorized
denominations and for the same aggregate Undivided Interests will be issued to
the designated transferee or transferees.

          As provided in the Agreement and subject to certain limitations
therein set forth, Class B Certificates are exchangeable for new Class B
Certificates evidencing like aggregate Undivided Interests, as requested by the
Class B Certificateholder surrendering such Class B Certificates.  No service
charge may be imposed for any such exchange but the Transferor, Servicer, or
Transfer Agent and Registrar may require payment of a sum sufficient to cover
any tax or other governmental charge that may be imposed in connection
therewith.

          The Transferor, the Servicer, the Trustee, the Paying Agent and the
Transfer Agent and Registrar, and any agent of any of them, may treat the person
in whose name this Certificate is registered as the owner hereof for all
purposes, and neither the Transferor, the Servicer, the Trustee, the Paying
Agent and the Transfer Agent and Registrar, nor any agent of any of them or of
any such agent, shall be affected by notice to the contrary except in certain
circumstances described in the Agreement.

          The Agreement and any Supplement may be amended by the Transferor, the
Servicer and the Trustee, without the consent of certificateholders of any
Series then outstanding for any purpose, provided that (i) the Transferor shall
                                         --------                              
deliver an opinion of counsel acceptable to the Trustee to the effect that such
amendment will not adversely affect in any material respect the interest of such
certificateholders, and (ii) such amendment will not result in a withdrawal or
reduction of the rating of any outstanding Series.

          The Agreement and the Series 1997-10 Supplement may be amended by the
Transferor, the Servicer and the Trustee with the consent of the holders of
certificates evidencing undivided interests aggregating not less than 66-2/3%
of the investor interests of all Series adversely affected, for the purpose of
adding any provisions to, changing in any manner or eliminating any of the
provisions of the Agreement or the Series 1997-10 Supplement or of modifying in
any manner the rights of certificateholders of any then outstanding Series.  No
such amendment, however, may (a) reduce in any manner the amount of, or delay
the timing of, distributions required to be made on any such Series, (b) change
the definition of or the manner of calculating the interest of any
certificateholder of such Series, or (c) reduce the aforesaid percentage of
undivided interests the holders of which are required to consent to any

such amendment, in each case without the consent of all certificateholders of
all Series adversely affected.  Promptly following the execution of any
amendment to the Agreement, the Trustee will furnish written notice of the
substance of such amendment to each Class B Certificateholder.

                        CIA CERTIFICATE, SERIES 1997-10

Evidencing an undivided interest in a trust, the corpus of which consists of
receivables generated from time to time in the ordinary course of business in a
portfolio of VISA(R) and MasterCard(R)* credit card accounts generated or
to be generated by First USA Bank (the "Bank").

                 (Not an interest in or a recourse obligation
                  of First USA Bank or any affiliate thereof)

          This certifies that __________________________, in its capacity as
Administrative Agent on behalf of the Group E1 Investors (the
"Certificateholder") is the registered owner of a fractional undivided interest
in the First USA

Credit Card Master Trust (the "Trust") issued pursuant to the Pooling and
Servicing Agreement, dated as of September 1, 1992 between the Bank, as
Transferor (the "Transferor") and as Servicer (the "Servicer"), and The Bank of
New York (Delaware), as trustee (the "Trustee") of the Trust (the "Agreement";
such term to include any Supplement or amendment thereto) as supplemented by the
Series 1997-10 Supplement (the "Series 1997-10 Supplement"), dated as of
December 23, 1997, between the Bank, as Transferor and Servicer, and the
Trustee. The corpus of the Trust consists of all of the Transferor's right,
title and interest in a portfolio of receivables (the "Receivables") existing in
certain VISA(R) and MasterCard(R) revolving credit card accounts identified in
the Agreement from time to time (the "Accounts"), all Receivables generated
under the Accounts from time to time thereafter, all monies due or to become due
and all amounts received with respect to the Receivables in existence in the
Accounts, all monies on deposit in certain bank accounts (excluding any
investment earnings on such deposited amounts except as set forth in the Series
1997-10 Supplement), and all other assets and interests constituting the Trust
and all proceeds of the foregoing. The Receivables consist of amounts charged by
cardholders for goods and services and cash advances (such amounts, less the
amount of Discount Receivables, the "Principal Receivables"), plus the related
periodic finance charges (the "Periodic Finance Charges"), annual membership
fees ("Annual Membership Fees"), and amounts charged to the Accounts in respect
of cash advance finance charges, late fees, overlimit fees, return check fees
and similar fees and charges (the "Other Charges"). Receivables in an amount
equal to the product of the Yield Factor (initially 1.3%) and amounts charged by
cardholders for goods and services and cash advances (the "Discount
Receivables") will be allocated to the Certificates and treated as Finance
Charge Receivables (Discount Receivables, together with the Periodic Finance
Charges, Annual Membership Fees and Other Charges, the "Finance Charge
Receivables").

          Although a summary of certain provisions of the Agreement is set forth
below, this CIA Certificate does not purport to summarize the Agreement and
reference is made to the Agreement for information with respect to the
interests, rights, benefits, obligations, proceeds, and duties evidenced hereby
and the rights, duties and obligations of the Trustee. A copy of the Agreement
may be requested from the Trustee by writing to the Trustee at The Bank of New

(Delaware), White Clay Center, Route 273, Newark, Delaware, 19711, Attention:
Bond Administration. To the extent not defined herein, the capitalized terms
used herein have the meanings ascribed to them in the Agreement. This
Certificate is one of a Series of Certificates entitled "First USA Credit Card
Master Trust CIA Certificates, Series 1997-10" (the "CIA Certificates"), each of
which represents a fractional undivided interest in the Trust, and is issued
under and is subject to the terms, provisions and conditions of the Agreement,
to which Agreement, as amended from time to time, the Certificateholder by
virtue of the acceptance hereof assents and by which the Certificateholder is
bound. In the case of any conflict between terms specified in this CIA
Certificate and terms specified in the Agreement, the terms of the Agreement
shall govern.

          The Transferor has structured the Agreement, the CIA Certificates, the
Exchangeable Certificate Purchase Agreement, the First USA Credit Card Master
Trust Class A Floating Rate Asset Backed Certificates, Series 1997-10 (the
"Class A Certificates") and the First USA Credit Card Master Trust Class B
Floating Rate Asset Backed Certificates, Series 1997-10 (the "Class B
Certificates") with the intention that the CIA Certificates, the Class A
Certificates and the Class B Certificates will qualify under applicable tax law
as indebtedness, and the Transferor and each holder of a CIA Certificate (a "CIA
Certificateholder") or any interest therein, by acceptance of its CIA
Certificate or any interest therein, agrees to treat the CIA Certificates for
purposes of federal, state, local and foreign income or franchise taxes and any
other tax imposed on or measured by income, as indebtedness. Notwithstanding the
foregoing, in the event that the CIA Certificates are not classified as debt as
set forth above, it is the intention of the parties hereto that such CIA
Certificates be classified as interests in a partnership. In the event that the
yield to a CIA Certificateholder is not treated as a guaranteed payment but as
an allocation of partnership income, it is the intention of the parties that
gross income of the partnership be allocated to the CIA Certificateholders in an
amount equal to: (i) interest accrued on the CIA Certificates; (ii) any amount
that would, if the CIA Certificates were classified as debt, be treated as
original issue discount (to the extent not included in (i)); and (iii) any
losses previously allocated to the CIA Certificateholders. Losses shall be
allocated to a CIA Certificateholder only to the extent that the Invested Amount
is reduced by any such loss.

          The Trust's assets are allocated in part to the holders of the Class A
Certificates, the holders of the Class B Certificates and the holders of the CIA
Certificates (such holders together the "Investor Certificateholders") with the
remainder allocated to holders of other Series of Certificates issued by the
Trust and outstanding from time to time and to the Transferor.  In addition to
the Class A Certificates, the Class B Certificates and the CIA Certificates,
the Exchangeable Transferor Certificate will be reissued pursuant to the
Agreement and will represent the Transferor's interest in the Trust.  The
reissued Exchangeable Transferor Certificate will represent the interest in the
Principal Receivables not represented by the Class A Certificates, the Class B
Certificates and the CIA Certificates (together the "Investor Certificates") or
any other Series of Certificates.  The Exchangeable Transferor Certificate may
be exchanged by the Transferor pursuant to the Agreement for one or more Series
of Certificates and a reissued Exchangeable Transferor Certificate upon the
conditions set forth in the Agreement.  In addition, to the extent permitted for
any Series of Certificates by the related Supplement, the Certificateholders of
such Series may tender their Certificates and the Transferor may tender the 
Exchangeable Transferor Certificate in exchange for one or more Series of
Certificates and a reissued Exchangeable Transferor Certificate.

          The CIA Initial Invested Amount is $80,121,000.  The CIA Invested
Amount for any monthly Distribution Date will be an amount equal to (i) the CIA
Initial Invested Amount, minus (ii) the aggregate amount of principal payments
                         -----                                                 
made to the CIA Certificateholders prior to such Distribution Date, minus (iii)
                                                                    -----      
the aggregate amount of CIA Investor Charge-Offs for all prior Distribution
Dates allocated to the CIA Certificates, minus (iv) the aggregate amount of
                                         -----                             
Reallocated Principal Collections for all prior Distribution Dates which have
been used to fund the Class A Required Amount or the Class B Required Amount
allocated to the CIA Certificates, minus (v) an amount equal to the aggregate
                                   -----                                     
amount by which the CIA Invested Amount has been reduced to fund the Class A
Investor Default Amount and the Class B Investor Default Amount on all prior
Distribution Dates as described in the Agreement and allocated to the CIA
Certificates and plus (vi) the aggregate amount of Excess Finance Charge
                 ----                                                   
Collections and certain other amounts allocated and available for purposes of
reimbursing amounts deducted pursuant to the foregoing clauses (ii), (iii) and

                                      C-5

(iv); provided, however, that the CIA Invested Amount may not be reduced below

zero.

          The CIA Certificates will bear interest at the rate of _____% per
annum from December 23, 1997 through January 19, 1998, and for each Interest
Period thereafter, the CIA Certificates will bear interest at a per annum rate
of _____% in excess of LIBOR as determined by the Trustee on the related LIBOR
Determination Date (each such rate as in effect from time to time, the "CIA
Certificate Rate"). Interest will be distributed to the extent of available
funds on January 20, 1998, and on the seventeenth day of each month thereafter,
or if such day is not a Business Day, the next succeeding Business Day until the
earlier of the day on which the CIA Invested Amount is paid in full and the
Scheduled Series 1997-10 Termination Date (each such date a "Distribution
Date"), in an amount equal to the product of (a) the actual number of days in
the related Interest Period divided by 360, (b) the CIA Certificate Rate and (c)
the aggregate outstanding principal balance of the CIA Certificates on the last
day of the Monthly Period immediately preceding such Distribution Date. Interest
for a Distribution Date will accrue from and including the previous Distribution
Date (or in the case of the first Distribution Date, from and including the
Closing Date), to, and including, the day immediately preceding the current
Distribution Date. Interest payments will be made on January 20, 1998 and on
each Distribution Date thereafter until the Scheduled Series 1997-10 Termination
Date. Interest will be payable monthly on each Distribution Date to the CIA
Certificateholders of record as of the related Record Date. The Record Date with
respect to any Distribution Date shall be the last day of the calendar month
preceding such Distribution Date.

          The Bank, as Servicer, is entitled to receive as servicing
compensation a monthly servicing fee in an amount equal to, with respect to each
Series, one-twelfth of the product of the applicable Servicing Fee Percentage
and the Invested Amount for such Series with respect to the related Monthly
Period. The share of the Servicing Fee for each Monthly Period allocable to the
CIA Certificates shall be equal to one-twelfth of the product of the Series
Servicing Fee Percentage and the CIA Adjusted Invested Amount on the last day of
the preceding Monthly Period (the "CIA Monthly Servicing Fee").

                                      C-6
<PAGE>
 
          As described in the Agreement, Collections of Principal Receivables
with respect to any Monthly Period will be allocated on the related
Determination Date on the basis of the aggregate Investor Percentage of all
Series and the Transferor Percentage with respect to the Principal Receivables.
Such allocation will be performed both during the Revolving Period and any
Amortization Period. Throughout the existence of the Trust, the Servicer will
allocate to the Transferor, as holder of the Exchangeable Transferor
Certificate, an amount equal to the Transferor Percentage of the aggregate
amount of Collections of Finance Charge Receivables and Principal Receivables
for each Monthly Period. During the Revolving Period relating to the Investor
Certificates, the Class B Floating Allocation Percentage of Collections of
Principal Receivables and the CIA Floating Allocation Percentage of Collections
of Principal Receivables will be applied first as Reallocated Principal
Collections, to the extent required, and any remaining amounts together with the
Class A Floating Allocation Percentage of Principal Receivables will be
distributed first to the certificateholders of other Series to the extent of the
amount of Principal Shortfalls, if any, and then to the Transferor in an amount
not to exceed the amount of the Transferor Interest.

          Unless a Pay Out Event has occurred, the Accumulation Period will
begin at the close of business on the last day of the Revolving Period and will
end on the earlier of (i) the commencement of the Rapid Amortization Period,
(ii) payment of the Invested Amount in full and (iii) the Scheduled Series 1997-
10 Termination Date. During the Accumulation Period, the portion of Available
Investor Principal Collections not applied to Class A Monthly Principal, Class B
Monthly Principal or CIA Monthly Principal on a Transfer Date will generally be
treated as Excess Principal Collections.

          Upon written notice to the Trustee and satisfaction of certain
conditions, the Servicer may elect to postpone the commencement of the
Accumulation Period, and extend the length of the Revolving Period.

          On the January 2001 Distribution Date if the Class A Invested Amount
and the Class B Invested Amount each is paid in full, Available Investor
Principal Collections and Excess Principal Collections allocable to Series 1997-
10 remaining after payment in full of the Class A Invested Amount and the Class
B Invested Amount will be used to pay

                                      C-7
<PAGE>
 
the CIA Invested Amount until the earlier of the date on which the CIA Invested
Amount is paid in full and the Scheduled Series 1997-10 Termination Date, as
described in the Agreement.

          If a Pay Out Event occurs during the Accumulation Period, the Rapid
Amortization Period will commence and any amount on deposit in the Principal
Funding Account will be distributed to the Certificateholders of each Class of
Certificates, sequentially, in order of seniority, on the Distribution Date
following the Monthly Period in which the Rapid Amortization Period commences.

          During the period beginning on the earlier of the day on which a Pay
Out Event occurs and the Class A Scheduled Payment Date if the Invested Amount
is not paid in full on such date, and ending on the earlier of (i) the date on
which the Class A Invested Amount, the Class B Invested Amount and the CIA
Invested Amount have been paid in full and (ii) the Scheduled Series 1997-10
Termination Date (the "Rapid Amortization Period"), collections of Principal
Receivables allocated to the Invested Amount will no longer be paid to the
holder of the Exchangeable Transferor Certificate or to the holders of the
certificates of any other Series or, if the Accumulation Period has commenced,
deposited in the Principal Funding Account, but instead will be distributed to
the Class A Certificateholders and, following payment in full of the Class A
Invested Amount, to the Class B Certificateholders, and, following payment in
full of the Class B Invested Amount, to the CIA Certificateholders, monthly on
each Distribution Date beginning with the Distribution Date in the month
following the commencement of the Rapid Amortization Period.

          Principal payments on the CIA Certificates will be, during the
Accumulation Period, funded by deposits to the Principal Funding Account or,
during the Rapid Amortization Period, made monthly, and will commence on the
date (the "CIA Principal Commencement Date") which is (a) with respect to the
Accumulation Period, the first Distribution Date on which an amount equal to the
sum of the Class A Invested Amount and the Class B Invested Amount has been
deposited in the Principal Funding Account and allocated to the Class A
Certificates and the Class B Certificates or (b) with respect to the Rapid
Amortization Period, the Distribution Date on which the Class A Invested Amount
and the Class B Invested Amount have each been paid in full or, if there

                                      C-8
<PAGE>
 
are no Principal Receivables allocable to the Investor Certificates remaining
after payments have been made to the Class A Certificates and the Class B
Certificates on such Distribution Date, the Distribution Date following the
Distribution Date on which the Class A Invested Amount and the Class B Invested
Amount have each been paid in full. After payment in full of the Class A
Invested Amount and the Class B Invested Amount, amounts deposited in the
Principal Funding Account for the benefit of the CIA Certificates will be paid
to the CIA Certificateholders on the January 2001 Distribution Date and on each
Distribution Date during the Rapid Amortization Period beginning with the CIA
Principal Commencement Date, and thereafter until the payment in full of the CIA
Invested Amount or the termination of the Trust, the Percentage Allocation of
all Collections of Principal Receivables and certain other amounts for the
preceding Monthly Period remaining after payment in full of the Class A Invested
Amount and the Class B Invested Amount will be distributed to the CIA
Certificateholders.

          Subject to the Agreement, payments of principal are limited to the
unpaid CIA Invested Amount of the CIA Certificates, which may be less than the
unpaid balance of the CIA Certificates pursuant to the terms of the Agreement.
All principal of and interest on the CIA Certificates is due and payable no
later than September 17, 2003 (or if such day is not a Business Day, the next
succeeding Business Day) (the "Scheduled Series 1997-10 Termination Date").
After the Scheduled Series 1997-10 Termination Date, neither the Trust nor the
Transferor will have any further obligation to distribute principal or interest
on the CIA Certificates. In the event that the Invested Amount is greater than
zero on the Series Termination Date, the Trustee will sell or cause to be sold,
to the extent necessary, an amount of interests in the Receivables or certain of
the Receivables up to 110% of the sum of the Class A Invested Amount, the Class
B Invested Amount and the CIA Invested Amount at the close of business on such
date (but not more than the total amount of Receivables allocable to the
Investor Certificates), and shall pay the proceeds to the Class A
Certificateholders pro rata then to the Class B Certificateholders pro rata and
then to the CIA Certificateholders pro rata in final payment of the Investor
Certificates.

          The transfer of this Certificate shall be registered in the
Certificate Register upon surrender of this Certificate for registration of
transfer at any office or

                                      C-9

agency maintained by the Transfer Agent and Registrar accompanied by a written
instrument of transfer in a form satisfactory to the Trustee and the Transfer
Agent and Registrar duly executed by the Certificateholder or such
Certificateholder's attorney duly authorized in writing, and thereupon one or
more new CIA Certificates of authorized denominations and for the same aggregate
Undivided Interests will be issued to the designated transferee or transferees.

          As provided in the Agreement and subject to certain limitations
therein set forth, CIA Certificates are exchangeable for new CIA Certificates
evidencing like aggregate Undivided Interests, as requested by the CIA
Certificateholder surrendering such CIA Certificates. No service charge may be
imposed for any such exchange but the Transferor, Servicer, or Transfer Agent
and Registrar may require payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in connection therewith.

          The Transferor, the Servicer, the Trustee, the Paying Agent and the
Transfer Agent and Registrar, and any agent of any of them, may treat the person
in whose name this Certificate is registered as the owner hereof for all
purposes, and neither the Transferor, the Servicer, the Trustee, the Paying
Agent and the Transfer Agent and Registrar, nor any agent of any of them or of
any such agent, shall be affected by notice to the contrary except in certain
circumstances described in the Agreement.

          The Agreement and any Supplement may be amended by the Transferor, the
Servicer and the Trustee, without the consent of certificateholders of any
Series then outstanding for any purpose, provided that (i) the Transferor shall
                                         --------                              
deliver an opinion of counsel acceptable to the Trustee to the effect that such
amendment will not adversely affect in any material respect the interest of such
certificateholders, and (ii) such amendment will not result in a withdrawal or
reduction of the rating of any outstanding Series.

          The Agreement and the Series 1997-10 Supplement may be amended by the
Transferor, the Servicer and the Trustee with the consent of the holders of
certificates evidencing undivided interests aggregating not less than 66-2/3% of
the investor interests of all Series adversely affected, for the purpose of
adding any provisions to, changing in any manner or eliminating any of the
provisions

                                     C-10
<PAGE>
 
of the Agreement or the Series 1997-10 Supplement or of modifying in any manner
the rights of certificateholders of any then outstanding Series.  No such
amendment, however, may (a) reduce in any manner the amount of, or delay the
timing of, distributions required to be made on any such Series, (b) change the
definition of or the manner of calculating the interest of any certificateholder
of such Series, or (c) reduce the aforesaid percentage of undivided interests
the holders of which are required to consent to any such amendment, in each case
without the consent of all certificateholders of all Series adversely affected.
Promptly following the execution of any amendment to the Agreement, the Trustee
will furnish written notice of the substance of such amendment to each CIA
Certificateholder.

          The holder of this Certificate by its acceptance hereof agrees that it
will not institute or join against the Trust or the Transferor any bankruptcy,
reorganization, arrangement, insolvency or liquidation proceeding or other
proceeding under any federal or state bankruptcy or similar law, for one year
and a day after the payment in full of the last outstanding investor certificate
issued by the First USA Credit Card Master Trust; provided, that the foregoing
                                                  --------                    
shall not limit the right of the holder of this Certificate to file any claim in
or otherwise take any action with respect to any such bankruptcy,
reorganization, arrangement, insolvency or liquidation proceeding that was
instituted by any person other than a CIA Certificateholder.

          The holder hereof by its acceptance of this Certificate further agrees
that it will report its interest in the CIA Investor Principal Balance, with
respect to all taxes, in a manner consistent with the intended characterization
referred to in Section 3.07 of the Agreement.

          Neither this Certificate nor any interest herein may be sold conveyed,
assigned, hypothecated, pledged, participated, or otherwise transferred, except
in accordance with the Agreement, and any such transfer will be permitted only
if it consists of a pro rata percentage interest in all payments made with
respect to this Certificate and is in respect of at least $10,000,000 in
principal amount (or such smaller amount to which the Transferor may consent in
writing but not less than $20,000).

          Neither this Certificate nor any interest herein may be transferred to
any person, unless the transferee

                                     C-11
<PAGE>
 
shall have executed and delivered the certifications required by the Agreement
and the Exchangeable Certificate Purchase Agreement and each of the Transferor
and the Servicer shall have granted (provided that the proposed transferee
otherwise satisfies all conditions required by the Agreement and the
Exchangeable Certificate Purchase Agreement) its prior consent thereto. Such
consent shall be granted unless the Transferor determines in its sole and
absolute discretion that the proposed transfer would create a risk that the
Trust would be classified for federal or any applicable state tax purposes as an
association or publicly traded partnership taxable as a corporation.
Notwithstanding the foregoing, any attempted transfer of this Certificate or an
interest herein that would cause the aggregate number of (i) holders of a right
to receive interest or principal with respect to the CIA Certificates (or other
interests in the Trust), other than certificates (or other such interests) with
respect to which an opinion is rendered that such certificates (or other such
interests) will be treated as debt for federal income tax purposes, and (ii) any
holders of a right to receive any amount in respect of the Transferor Interest,
to exceed ninety nine shall be void.

          The holder of this Certificate or any interest therein hereby
certifies that it is either (A)(i) a citizen or resident of the United States,
(ii) a corporation, partnership or other entity organized in or under the laws
of the United States or any political subdivision thereof which, if a tax-exempt
entity, recognizes that payments with respect to this Certificate may constitute
unrelated business taxable income or (iii) a person not described in (i) or (ii)
whose ownership of this Certificate is effectively connected with the conduct of
a trade or business within the United States (within the meaning of the Code)
and whose ownership of any interest in this Certificate will not result in any
withholding obligation with respect to any payments with respect to this
Certificate by any person (other than withholding, if any, under Section 1446 of
the Code)and who will furnish to the Servicer and the Trustee a properly
executed United States Internal Revenue Service Form 4224 (and will agree to
provide a new Form 4224 upon the expiration or obsolescence of any previously
delivered form and comparable statement in accordance with applicable United
States laws), or (B) an estate or trust the income of which is includible in
gross income for United States federal income tax purposes.

          Unless the certificate of authentication hereon has been executed by
or on behalf of the Trustee, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement, or be valid for any purpose.

          IN WITNESS WHEREOF, the Transferor has caused this Certificate to be
duly executed on this 23rd day of December, 1997.

                                   [Issue Description]


Ladies and Gentlemen:

  This letter sets forth our understanding with respect to certain matters 
relating to the above-referenced issue (the "Securities"). Trustee will act as 
trustee with respect to the Securities pursuant to a trust indenture dated as of
                                                                           -----
September 1       , 1992* (the "Document"). Banc One Capital Corporation** 
- ------------------     -                    ------------------------------------
                                                     ["Underwriter"]
is distributing the Securities through The Depository Trust Company ("DTC").

  To induce DTC to accept the Securities as eligible for deposit at DTC, and to 
act in accordance with its Rules with respect to the Securities, Issuer and 
Trustee make the following representations to DTC:

  1. Prior to closing on the Securities on  December 23  , 1997 , there shall be
                                           --------------     --
deposited with DTC one Security certificate registered in the name of DTC's 
nominee, Cede & Co., for each stated maturity of the Securities in the face 
amounts set forth on Schedule A hereto, the total of
- -------------------------
*  As supplemented as of December 23, 1997
** As Representative for itself, Credit Suisse First Boston Corporation, 
   Goldman, Sachs & Co., J.P. Morgan Securities Inc. and Deutsche Morgan 
   Grenfell Inc.
<PAGE>
 
which represents 100% of the principal amount of such Securities. If, however, 
the aggregate principal amount of any maturity exceeds $200 million, one 
certificate will be issued with respect to each $200 million of principal amount
and an additional certificate will be issued with respect to any remaining 
principal amount. Each Security certificate shall bear the following legend:

        Unless this certificate is presented by an authorized representative of
     The Depository Trust Company, a New York corporation ("DTC"), to Issuer or
     its agent for registration of transfer, exchange, or payment, and any
     certificate issued is registered in the name of Cede & Co. or in such other
     name as is requested by an authorized representative of DTC (and any
     payment is made to Cede & Co. or to such other entity as is requested by an
     authorized representative of DTC), ANY TRANSFER, PLEDGE, OR OTHER USE
     HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL inasmuch as
     the registered owner hereof, Cede & Co., has an interest herein.

     2. In the event of any solicitation of consents from or voting by holders 
of the Securities, Issuer or Trustee shall establish a record date for such 
purposes (with no provision for revocation of consents or votes by subsequent 
holders) and shall send notice of such record date to DTC not less than 15 
calendar days in advance of such record date. Notices to DTC pursuant to this 
Paragraph by telecopy shall be sent to DTC's Reorganization Department at (212) 
709-6896 or (212) 709-6897, and receipt of such notices shall be confirmed by 
telephoning (212) 709-6870. Notices to DTC pursuant to this Paragraph by mail or
by any other means shall be sent to DTC's Reorganization Department as indicated
in Paragraph 4.

     3. In the event of a full or partial redemption, Issuer or Trustee shall 
send a notice to DTC specifying: (a) the amount of the redemption or refunding; 
(b) in the case of a refunding, the maturity date(s) established under the 
refunding; and (c) the date such notice is to be mailed to Security holders or 
published (the "Publication Date"). Such notice shall be sent to DTC by a secure
means (e.g., legible telecopy, registered or certified mail, overnight delivery)
in a timely manner designed to assure that such notice is in DTC's possession no
later than the close of business on the business day before or, if possible, two
business days before the Publication Date. Issuer or Trustee shall forward such 
notice either in a separate secure transmission for each CUSIP number or in a 
secure transmission for multiple CUSIP numbers (if applicable) which includes a 
manifest or list of each CUSIP number submitted in that transmission. (The party
sending such notice shall have a method to verify subsequently the use of such 
means and the timeliness of such notice.) The Publication Date shall be not less
than 30 days nor more than 60 days prior to the redemption date or, in the case 
of an advance refunding, the date that the proceeds are deposited in escrow. 
Notices to DTC pursuant to this Paragraph by telecopy shall be sent to DTC's 
Call Notification Department at (516) 227-4039 or (516) 227-4190. If the party 
sending the notice does not receive a telecopy receipt from DTC confirming that 
the notice has been received, such party shall telephone (516) 227-4070. Notices
to DTC pursuant to this Paragraph by mail or by any other means shall be sent 
to:

          Manager: Call Notification Department
          The Depository Trust Company
          711 Stewart Avenue
          Garden City, NY 11530-4719

     4. In the event of an invitation to tender the Securities (including 
mandatory tenders, exchanges, and capital changes), notice by Issuer or Trustee 
to Security holders specifying the terms of the tender and the Publication Date 
of such notice shall be sent to DTC by a secure means in the manner set forth in
the preceding Paragraph. Notices to DTC pursuant to this Paragraph and notices
of other corporate actions by telecopy shall be sent to DTC's Reorganization
Department at (212) 709-1093


                                      -2-

or (212) 709-1094, and receipt of such notices shall be confirmed by telephoning

     5. All notices and payment advices sent to DTC shall contain the CUSIP 
number of the Securities.

     6. Trustee shall send DTC written notice with respect to the dollar amount 
per $1,000 original face value (or other minimum authorized denomination if less
than $1,000 face value) payable on each payment date allocated as to the 
interest and principal portions thereof preferably 5, but not less than 2,
business days prior such payment date. Such notices, which shall also contain
the current pool factor, any special adjustments to principal/interest rates
(e.g, adjustments due to deferred interest or shortfall), and Trustee contact's
name and telephone number, shall be sent by telecopy to DTC's Dividend
Department at (212) 709-1723, or if by mail or by any other means to:

          Manager; Announcements
          Dividend Department
          The Depository Trust Company
          7 Hanover Square, 22nd Floor
          New York, NY 10004-2695

     7. [Note: Issuer must represent one of the following, and cross out the 
other:] [The interest accrual period is payment date to payment date.]

     8. Trustee must provide DTC, no later than noon (Eastern Time) on the 
payment date, CUSIP numbers for each issuer for which payment is being sent, as 
well as the dollar amount of the payment for each issue. Notification of payment
details should be sent using automated communications.

     9. Interest payments and principal payments that are part of periodic 
principal-and-interest payments shall be received by Cede & Co., as nominee of 
DTC, or its registered assigns in same-day funds, no later than 2:30 p.m. 
(Eastern Time) on each payment date (in accordance with existing arrangements 
between Issuer or Trustee and DTC). Absent any other arrangements between Issuer
or Trustee and DTC, such funds shall be wired as follows:

          For credit to A/C The Depository Trust Company
          Dividend Deposit Account 066-026776

Issuer or Trustee shall provide interest payment information to a standard 
announcement service subscribed to by DTC. In the unlikely event that no such 
service exists, Issuer or Trustee shall provide interest payment information 
directly to DTC in advance of the interest payment date as soon as the 
information is available. This information should be conveyed directly to DTC 
electronically. If electronic transmission is not available, absent any other 
arrangements between Trustee and DTC, such information should be sent by 
telecopy to DTC's Dividend Department at (212) 709-1723 or


                                      -3-

     10.  DTC shall receive maturity and redemption payments allocated with 
respect to each CUSIP number on the payable date in same-day funds by 2:30 p.m. 
(Eastern Time). Absent any other arrangements between Trustee and DTC, such
payments shall be wired as follows:


          The Chase Manhattan Bank
          ABA 021000021
          For credit to A/C The Depository Trust Company

been furnished to Trustee.

     11.  DTC shall receive all reorganization payments and CUSIP-level detail 
resulting from corporate actions (such as tender offers, remarketings, or 
mergers) on the first payable date in same-day funds by 2:30 p.m. (Eastern 
Time). Absent any other arrangements between Trustee and DTC, such payments

          Reorganization Account 066-027608 


     12.  DTC may direct Issuer or Trustee to use any other number or address as
the number or address to which notices or payments of interest or principal may 
be sent.

     13.  In the event of a redemption, acceleration, or any other similar 
transaction (e.g., tender made and accepted in response to Issuer's or Trustee's
invitation) necessitating a reduction in the aggregate principal amount of 
Securities outstanding or an advance refunding of part of the Securities 
outstanding, DTC, in its discretion: (a) may request Issuer or Trustee to issue 
and authenticate a new Security certificate; or (b) may make an appropriate 
notation on the Security certificate indicating the date and amount of such 
reduction in principal except in the case of final maturity, in which case the 
certificate will be presented to Issuer or Trustee prior to payment, if 
required.

     14.  In the event that Issuer determines that beneficial owners of 
Securities shall be able to obtain certificated Securities, Issuer or Trustee 
shall notify DTC of the availability of certificates. In such event, Issuer or 
Trustee shall issue, transfer, and exchange certificates in appropriate amounts,
as required by DTC and others.

     15.  DTC may discontinue providing its services as securities depository 
with respect to the Securities at any time by giving reasonable notice to Issuer
or Trustee (at which time DTC will confirm with Issuer or Trustee the aggregate 
principal amount of Securities outstanding). Under such circumstances, at DTC's 
request Issuer and Trustee shall cooperate fully with DTC by taking

                                      -4-
<PAGE>
 
appropriate action to make available one or more separate certificates 
evidencing Securities to any DTC Participant having Securities credited to its 
DTC accounts.

     16. Issuer: (a) understands that DTC has no obligation to, and will not,
communicate to its Participants or to any person having an interest in the
Securities any information contained in the Security certificate(s); and (b)
acknowledges that neither DTC's Participants nor any person having an interest
in the Securities shall be deemed to have notice of the provisions of the
Security certificates by virtue of submission of such certificate(s) to DTC.

     17. Nothing herein shall be deemed to require Trustee to advance funds on 
behalf of Issuer.

     18. Rider 5A is incorporated herein.

                                                                      ----------

                      SAMPLE OFFICIAL STATEMENT LANGUAGE
                      DESCRIBING BOOK-ENTRY-ONLY ISSUANCE
                      -----------------------------------
(Prepared by DTC--bracketed material may be applicable only to certain issues)

     1.   The Depository Trust Company ("DTC"), New York, NY, will act as 
securities depository for the securities (the "Securities").  The Securities 
will be issued as fully-registered securities registered in the name of Cede & 
Co. (DTC's partnership nominee).  One fully-registered Security certificate will
be issued for [each issue of] the Securities, [each] in the aggregate principal 
amount of such issue, and will be deposited with DTC.  [If, however, the 
aggregate principal amount of [any] issue exceeds $200 million, one certificate 
will be issued with respect to each $200 million of principal amount and an 
additional certificate will be issued with respect to any remaining principal 
amount of such issue.]

     2.   DTC is a limited-purpose trust company organized under the New York 
Banking Law, a "banking organization" within the meaning of the New York Banking
Law, a member of the Federal Reserve System, a "clearing corporation" within the
meaning of the New York Uniform Commercial Code, and a "clearing agency" 
registered pursuant to the provisions of Section 17A of the Securities Exchange 
Act of 1934.  DTC holds securities that its participants ("Participants") 
deposit with DTC.  DTC also facilitates the settlement among Participants of 
securities transactions, such as transfers and pledges, in deposited securities 
through electronic computerized book-entry changes in Participants' accounts, 
thereby eliminating the need for physical movement of securities certificates.  
Direct Participants include securities brokers and dealers, banks, trust 
companies, clearing corporations, and certain other organizations.  DTC is owned
by a number of its Direct Participants and by the New York Stock Exchange, Inc.,
the American Stock Exchange, Inc., and the National Association of Securities 
Dealers, Inc.  Access to the DTC system is also available to others such as 
securities brokers and dealers, banks, and trust companies that clear through or
maintain a custodial relationship with a Direct Participant, either directly or 
indirectly ("Indirect Participants").  The Rules applicable to DTC and its 
Participants are on file with the Securities and Exchange Commission.

     3.   Purchases of Securities under the DTC system must be made by or 
through Direct Participants, which will receive a credit for the Securities on 
DTC's records.  The ownership interest of each actual purchaser of each Security
("Beneficial Owner") is in turn to be recorded on the Direct and Indirect 
Participants' records.  Beneficial Owners will not receive written confirmation 
from DTC of their purchase, but Beneficial Owners are expected to receive 
written confirmations providing details of the transaction, as well as periodic 
statements of their holdings, from the Direct or Indirect Participant through 
which the Beneficial Owner entered into the transaction.  Transfers of ownership
interests in the Securities are to be accomplished by entries made on the books 
of Participants acting on behalf of Beneficial Owners.  Beneficial Owners will 
not receive certificates representing their ownership interests in Securities, 
except in the event that use of the book-entry system for the Securities is 
discontinued.

     4.   To facilitate subsequent transfers, all Securities deposited by 
Participants with DTC are registered in the name of DTC's partnership nominee, 
Cede & Co.  The deposit of Securities with DTC and their registration in the 
name of Cede & Co. effect no change in beneficial ownership.  DTC has no 
knowledge of the actual Beneficial Owners of the Securities; DTC's records 
reflect only the identity of the Direct Participants to whose accounts such 
Securities are credited, which may or may not be the Beneficial Owners.  The 
Participants will remain responsible for keeping account of their holdings on 
behalf of their customers.

     5.   Conveyance of notices and other communications by DTC to Direct 
Participants, by Direct Participants to Indirect Participants, and by Direct 
Participants and Indirect Participants to Beneficial Owners will be governed by 
arrangements among them, subject to any statutory or regulatory requirements as 
may be in effect from time to time.

     [6.   Redemption notices shall be sent to Cede & Co.  If less than all of 
the Securities within an issue are being redeemed, DTC's practice is to 
determine by lot the amount of the interest of each Direct Participant in such 
issue to be redeemed.]

                                      -i-

<PAGE>
 
     7.   Neither DTC nor Cede & Co. will consent or vote with respect to 
Securities.  Under its usual procedures, DTC mails an Omnibus Proxy to Issuer as
soon as possible after the record date.  The Omnibus Proxy assigns Cede & Co.'s 
consenting or voting rights to those Direct Participants to whose accounts the 
Securities are credited on the record date (identified in a listing attached to 
the Omnibus Proxy).

     8.   Principal and interest payments on the Securities will be made to DTC.
 DTC's practice is to credit Direct Participants' accounts on payable date in
 accordance with their respective holdings shown on DTC's records unless DTC has
 reason to believe that it will not receive payment on payable date. Payments by
 Participants to Beneficial Owners will be governed by standing instructions and
 customary practices, as is the case with securities held for the accounts of
 customers in bearer form or registered in "street name," and will be the
 responsibility of such Participant and not of DTC, Trustee, or Issuer, subject
 to any statutory or regulatory requirements as may be in effect from time to
 time. Payment of principal and interest to DTC is the responsibility of Issuer
 or Trustee, disbursement of such payments to Direct Participants shall be the
 responsibility of DTC, and disbursement of such payments to the Beneficial
 Owners shall be the responsibility of Direct and Indirect Participants.

     [9.  A Beneficial Owner shall give notice to elect to have its Securities
purchased or tendered, through its Participant, to Trustee [or Tender/
Remarketing Agent], and shall effect delivery of such Securities by
causing the Direct Participant to transfer the Participant's interest in the
Securities, on DTC's records, to Trustee [or Tender/Remarketing Agent]. The
requirement for physical delivery of Securities in connection with an optional
tender or a mandatory purchase will be deemed satisfied when the ownership
rights in the Securities are transferred by Direct Participants on DTC's records
and followed by a book-entry credit of tendered Securities to Trustee [or
Tender/Remarketing Agent's], DTC account.]

     10.  DTC may discontinue providing its services as securities depository
with respect to the Securities at any time by giving reasonable notice to Issuer
or Agent. Under such circumstances, in the event that a successor securities
depository is not obtained, Security certificates are required to be printed and
delivered.

     11.  Issuer may decide to discontinue use of the system of book-entry
transfers through DTC (or a successor securities depository). In that event,
Security certificates will be printed and delivered.

     12.  The information in this section concerning DTC and DTC's book-entry
system has been obtained from sources that Issuer believes to be reliable, but
Issuer takes no responsibility for the accuracy thereof.

        REPRESENTATIONS FOR DEPOSIT/WITHDRAWAL AT CUSTODIAN ("DWAC") --
               to be included in DTC Letter of Representations 
               ------------------------------------------------

     The Security certificate(s) shall remain in Agent's custody as a "Balance 
Certificate" subject to the provisions of the Balance Certificate Agreement 
between Agent and DTC currently in effect.

     On each day on which Agent is open for business and on which it receives an
instruction originated by a Participant through DTC's Deposit/Withdrawal at 
Custodian ("DWAC") system to increase the Participant's account by a specified 
number of shares, units, or obligations (a "Deposit Instruction"), Agent shall, 
before 6:30 p.m. (Eastern Time) that day, either approve or cancel the Deposit 
Instruction through the DWAC system.

     On each day on which Agent is open for business and on which it receives an
instruction originated by a Participant through the DWAC system to decrease the
Participant's account by a specified number of shares, units, or obligations (a
"Withdrawal Instruction"), Agent shall, before 6:30 p.m. (Eastern Time) that
day, either approve or cancel the Withdrawal Instruction through the DWAC
system.

     Agent agrees that its approval of a Deposit or Withdrawal Instruction shall
be deemed to be the receipt by DTC of a new, reissued or reregistered 
certificated security on registration of transfer to the name of Cede & Co. for
the quantity of Securities evidenced by the Balance Certificate after the
Deposit or Withdrawal Instruction is effected.
