              ------------------------------
the several Underwriters as follows:

              (a)  Immediately following the execution of this Agreement, the 
Bank will prepare a Prospectus Supplement setting

                                        8

<PAGE>   9



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 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

                                        9

<PAGE>   10



(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.

              (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 

                                       10

<PAGE>   11
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 1999-1 Series Term Sheet and a report on Form 8-K setting
forth all Computational Materials described in Section 3 hereof provided to the
Bank by any of the Underwriters 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 
              -------------------
the performance of its obligations under this Agreement, including (i) the
printing of the 1999-1 Series Term Sheet and any Computational Materials

there shall not have occurred (i) any change, or any development involving a

trading in securities generally on the New York Stock Exchange or the National
Association of Securities Dealers National Market system, or any setting of
minimum prices for trading on such exchange or market system; (iii) any

or in the over-the-counter market which materially impairs the investment
quality of the Certificates or makes it impractical or inadvisable to market the
Certificates; (iv) any banking moratorium declared by Federal, Delaware or New
York authorities; or (v) any outbreak or escalation of major hostilities or
armed conflict, any declaration of war by Congress, or any other substantial
national or international calamity or emergency if, in the judgment of the

completion of the sale of and payment for the Certificates.

              (d)  At the Closing Date, the Bank shall have furnished to the
Representative certificates of a vice president or more senior officer of the

furnished to the Representative his 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 organized and is validly existing
        as a national banking association in good standing under the laws of the
        United States 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 Transfer and Administration Agreement and the

        and transfer the Receivables;

                   (ii) 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;

                   (iii) Each of the Pooling and Servicing Agreement and the 
        Transfer and Administration Agreement has been duly authorized,
        executed and delivered by the Bank and constitutes the legal, valid and
        binding agreement of the Bank enforceable against the Bank in accordance
        with its terms, subject, as to enforceability, to (A) the effect of
        bankruptcy, insolvency, moratorium, receiver ship, reorganization,
        liquidation and other similar laws relating to or affecting the

<PAGE>   14



        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;

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

                   (v)  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;

                   (vi) 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 organizational documents or by-laws or any
        material indenture, loan agreement or other material agreement to which
        the Bank is a party or by which the Bank is bound;

                   (vii) 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

                                       14

<PAGE>   15



        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;

                   (viii) 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 opinion) comply as to form with the Act and the Rules and
        Regulations;

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

                   (x)  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 his discussions with
        the Bank, its accountants and others, however, no facts have come to its
        attention that cause him 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
        opinion), contains any untrue statement of a 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
that the Representative may rely on its opinion to Moody's Investors Service,

              (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 
        Transfer and Administration 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 national
        banking associations 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
        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

                                       16

<PAGE>   17



        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 Pooling and Servicing Agreement 
        and this Agreement conform in all material respects to the descriptions
        thereof contained in the Prospectus;

                   (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

                                       17

<PAGE>   18



        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 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.

Agency Agreement, dated as of December 4, 1995, between BONY and the Trustee
(the "Agency Agreement"), and counsel for the Trustee, shall have furnished to
      ----------------
the Representative its 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;

                   (iv) The Supplement has been duly authorized, executed and 
        delivered by the Trustee, and the Pooling and Servicing Agreement
        constitutes a legal, valid and binding agreement of the Trustee,
        enforceable against the Trustee in accordance with its 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 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 against the Trustee 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

                                       19

<PAGE>   20



        unenforceable, in whole or in part against the Trustee, 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 performance by the Trustee of its obligations under
        the Pooling and Servicing 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 performance by the Trustee of its obligations under
        the Pooling and Servicing 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.

Trust 1999-1 (the "Owner Trust") in connection with the Transfer and
Administration Agreement and the Indenture dated as of the Closing Date, between
the Owner Trust and The Bank of New York, as indenture trustee, shall have
furnished to the Representative its 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:

<PAGE>   21



                   (i)  The Owner Trust is a business trust duly formed, validly
        existing and in good standing under the laws of the State of Delaware
        and has the power and authority to execute, deliver and perform its
        obligations under the Transfer and Administration Agreement and the
        Indenture;

                   (ii) The Transfer and Administration Agreement, the Indenture
        and the secured notes issued by the Owner Trust pursuant to the
        Indenture (the "Notes") have been duly authorized, executed and
                        -----
        delivered by the Owner Trust, and the Transfer and Administration
        Agreement, the Indenture and the Notes constitute legal, valid and
        binding agreements of the Owner Trust, enforceable against the Owner
        Trust 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 insolvency, receivership,
        conservatorship or reorganization of, or other similar occurrence with
        respect to, the Owner Trustee), (y) that the enforceability of the
        Transfer and Administration Agreement, the Indenture and the Notes
        against the Owner Trust 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 Transfer and Administration Agreement and the
        Indenture may be unenforceable, in whole or in part against the Owner
        Trust, but the inclusion of such provisions does not affect the validity
        of the Transfer and Administration Agreement and the Indenture, taken as
        a whole, and the Transfer and Administration 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;

                                       21

<PAGE>   22



                   (iii) The execution and delivery by the Owner Trust of the 
        Transfer and Administration Agreement, the Indenture and the Notes and
        the performance by the Owner Trust of its obligations under the Transfer
        and Administration Agreement, the Indenture and the Notes do not
        conflict with or result in a violation of (x) any law or regulation of
        the State of Delaware applicable to the Owner Trust, or (y) the Trust
        Agreement; and

                   (iv) The execution and delivery by the Owner Trust of the 
        Transfer and Administration Agreement, the Indenture and the Notes and
        the performance by the Owner Trustee of its obligations under the
        Transfer and Administration Agreement, the Indenture and the Notes do
        not require any approval, authorization or other action by, or filing
        with, any governmental authority of the State of Delaware having
        jurisdiction over the Owner Trust, except such as have been obtained,
        taken or made.

              (k)  Richards, Layton & Finger, counsel for the Owner Trustee in
connection with the Trust Agreement, dated as of February 22, 1999, between the
Bank and the Owner Trustee, shall have furnished to the Representative its
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 Owner 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 Trust Agreement;

                   (ii) The Trust Agreement has been duly authorized, executed 
        and delivered by the Owner Trustee, and the Trust Agreement constitutes
        a legal, valid and binding agreement of the Owner Trustee, enforceable
        against the Owner Trustee in accordance with its terms, except (x) as
        may be limited by bankruptcy, insolvency, reorganization,

                                       22

<PAGE>   23



        moratorium or other similar laws relating to or affecting the rights of
        creditors generally (as such laws would apply in the event of the
        insolvency, receivership, conservatorship or reorganization of, or other
        similar occurrence with respect to, the Owner Trustee), (y) that the
        enforceability of the Trust Agreement against the Owner Trustee 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 Trust Agreement may be
        unenforceable, in whole or in part against the Owner Trustee, but the
        inclusion of such provisions does not affect the validity of the Trust
        Agreement, taken as a whole, and the Trust 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;

                   (iii) The execution and delivery by the Owner Trustee of the
        Trust Agreement, and the performance by the Owner Trustee of its
        obligations under the Trust 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 Owner Trustee, or (y) the organizational documents of the Owner
        Trustee; and

                   (iv) The execution and delivery by the Owner Trustee of the 
        Trust Agreement and the performance by the Owner Trustee of its
        obligations under the Trust 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 Owner
        Trustee, except such as have been obtained, taken or made.

              (l)  The Representative shall have received evidence satisfactory
to the Representative and its counsel that, on or before the Closing Date,
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.

              (m)  The Class A Certificates shall be rated "AAA" by Standard &

              (n)  All proceedings in connection with the transactions 
contemplated by this Agreement and all documents incident thereto shall be

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 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,

                                       24

<PAGE>   25



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 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,

                                       25

<PAGE>   26



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.

              (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

                                       26

<PAGE>   27



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 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

obligation of the Bank enforceable against the Bank in accordance with its

laws affecting creditors' rights generally and subject, as to enforceability, to
general principles of equity (regardless of whether enforcement is pursuant to a

the Trustee, nor the issuance, sale and delivery of the Certificates, nor the
execution or delivery of this Agreement, the Transfer and Administration
Agreement or the Pooling and Servicing Agreement, nor the consummation of any of

terms of the Certificates, the Pooling and Servicing Agreement, the Transfer and
Administration Agreement or this Agreement, will result in the breach of any
term or provision of the organizational documents or by-laws of the Bank, or
conflict with, result in a breach, violation or acceleration of, or constitute a
default under, the terms of any indenture or other agreement or instrument to
which the Bank is a party or by which it or its properties is bound or may be
affected or any statute, order or regulation applicable to the Bank of any
court, regulatory body, administrative agency, governmental body or arbitrator
having jurisdiction over the Bank or will result in the creation of any Lien

breach or violation of, any indenture or other agreement or instrument, or

                           (l) No Federal, state or local tax, including
intangibles tax or documentary stamp tax, the non-payment of which would result
in the imposition of a Lien on the Receivables or of transferee liability on the
Trustee, is imposed with respect to the conveyance of the Receivables from the
Bank to the Trust, or in connection with the issuance of the Certificates by the
Trust, or the holding of the Receivables by the Trust, or in connection with any
of the other transactions contemplated by this Agreement, the Transfer and
Administration Agreement or the Pooling and Servicing Agreement. Any taxes, fees
and other governmental charges in connection with the execution, delivery and

                           (n)  No consent, approval, authorization, order,
registration or qualification of or with any court or governmental agency or
body is required for the execution, delivery and performance by the Bank of or
compliance by the Bank with this Agreement, the Transfer and Administration
Agreement, the Pooling and Servicing Agreement, or the Certificates or the
consummation of the transactions contemplated hereby or thereby except the
filing of Uniform Commercial Code financing statements with respect to the
Receivables.

                                   (ii) Each Underwriter, severally, represents
          and warrants to the Bank that (a) it has not and will not use any

                  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


                                        8

<PAGE>   9
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 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


                                       9
<PAGE>   10
(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.

                           (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

                                       10

<PAGE>   11
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 1999-2 Series Term Sheet and a report on Form
8-K setting forth all Computational Materials described in Section 3 hereof
provided to the Bank by any of the Underwriters 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
                           -------------------

          executed and delivered by the Bank;

                                   (v) 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;

                                   (vi) 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
          organizational documents or by-laws or any material indenture, loan
          agreement or other material agreement to which the Bank is a party or
          by which the Bank is bound;

                                   (vii) 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;

                                   (viii) 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 opinion) comply as to form with the Act and
          the Rules and Regulations;

                                   (ix) 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

                                   (x) 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 his discussions with the Bank, its accountants and others,
          however, no facts have come to its attention that cause him 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 opinion), contains any untrue
          statement of a 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.

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

opinion or opinions, dated the Closing Date, substantially to the effect that:

                                   (i) Each of the Pooling and Servicing
          Agreement and the Transfer and Administration 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 national banking associations 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 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

          Servicing Agreement and this Agreement conform in all material
          respects to the descriptions thereof contained in the Prospectus;

                                   (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;

          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 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.

(the "Agency Agreement"), and counsel for the Trustee, shall have furnished to
      ----------------
the Representative its 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;

                                   (iv) The Supplement has been duly authorized,
          executed and delivered by the Trustee, and the Pooling and Servicing
          Agreement constitutes a legal, valid and binding agreement of the
          Trustee, enforceable against the Trustee in accordance with its 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 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 against the Trustee 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 against the Trustee, 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 performance by the Trustee of its
          obligations under the Pooling and Servicing 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 performance by the Trustee of its
          obligations under the Pooling and Servicing 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)     Richards, Layton & Finger, counsel for First
USA Secured Note Trust 1999-2 (the "Owner Trust") in connection with the
Transfer and Administration Agreement and the Indenture dated as of the Closing
Date, between the Owner Trust and The Bank of New York, as indenture trustee,

          Transfer and Administration Agreement, the Indenture and the Notes
          constitute legal, valid and binding agreements of the Owner Trust,
          enforceable against the Owner Trust in accordance with their
          respective terms, except (x) as may be limited by bankruptcy,

          equity (regardless of whether considered or applied in a proceeding in
          equity or at law), and (z) that certain remedial provisions of the
          Transfer and Administration Agreement and the Indenture may be

          Transfer and Administration Agreement and the Indenture, taken as a
          whole, and the Transfer and Administration 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;


                                       21

<PAGE>   22
                                   (iii) The execution and delivery by the Owner
          Trust of the Transfer and Administration Agreement, the Indenture and
          the Notes and the performance by the Owner Trust of its obligations
          under the Transfer and Administration Agreement, the Indenture and the
          Notes do not conflict with or result in a violation of (x) any law or
          regulation of the State of Delaware applicable to the Owner Trust, or
          (y) the Trust Agreement; and

                                   (iv) The execution and delivery by the Owner
          Trust of the Transfer and Administration Agreement, the Indenture and
          the Notes and the performance by the Owner Trustee of its obligations

          having jurisdiction over the Owner Trust, except such as have been
          obtained, taken or made.

                           (k)     Richards, Layton & Finger, counsel for the
Owner Trustee in connection with the Trust Agreement, dated as of February 22,
1999, between the Bank and the Owner Trustee, shall have furnished to the
Representative its 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 Owner Trustee is a banking
          corporation duly organized, validly existing and in good standing

          other similar occurrence with respect to, the Owner Trustee), (y) that
          the enforceability of the Trust Agreement against the Owner Trustee
          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 Trust
          Agreement may be unenforceable, in whole or in part against the Owner
          Trustee, but the inclusion of such provisions does not affect the

          Trustee of the Trust Agreement and the performance by the Owner

                  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 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,


                                       24

<PAGE>   25
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 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,


                                       25

<PAGE>   26
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.

                           (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


                                       26

<PAGE>   27
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 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.

<PAGE>   28
                  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 underwriter, 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 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


                                       28

<PAGE>   29
          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 issued or passed on and shall only issue or pass on in the United
Kingdom any document received by it in connection with the issue of the
Certificates to a person who is of a kind described in Article 11(3) of the
Financial Services Act 1986 (Investment Advertisements) (Exemptions) Order 1996
(as amended) or who is a person to whom the document may otherwise lawfully be
issued or passed on, (x) it has complied and shall comply with all applicable
provisions of the Financial Services Act 1986 and other applicable laws and
regulations with respect to anything done by it in relation to the Certificates
in, from or otherwise involving the United Kingdom and (y) if that Underwriter
is an authorized person under the Financial Services Act 1986, it has only
promoted and shall only promote (as that term is defined in Regulation 1.02 of
the Financial Services (Promotion of Unregulated Schemes) Regulations 1991) to
any person in the United Kingdom the scheme described in the Prospectus if that
person is of a kind described either in Section 76(2) of the Financial Services
Act 1986 or in Regulation 1.04 of the Financial Services (Promotion of
Unregulated Schemes) Regulations 1991.

                  12.      Notices. All communications provided for or permitted
                           -------

                           ------------------------------------------
Underwriter severally represents that it will not, at any time that such
Underwriter is acting as an "underwriter" (as defined in Section 2(11) of the
Act) with respect to the 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

the Bank.

                           ----------

                  (h) On the earlier to occur of the first Distribution Date
with respect to the Rapid Amortization Period or the Class A Scheduled Payment
Date and on each Distribution Date thereafter, the Trustee shall pay in
accordance with Section 5.01 of the Agreement from the Distribution Account the
amount so deposited into the Distribution Account pursuant to subsection
4.09(f)(i) of the Agreement on the related Transfer Date in the following
priority:

                           (i) an amount equal to the lesser of such amount on
         deposit in the Distribution Account and the Class A Invested Amount
         shall be paid to the Class A Certificateholders; and

                           (ii) on the Class B Principal Commencement Date and

                  (i) The Accumulation Period is scheduled to commence at the
close of business on January 31, 2003; provided, however, that, if the

Accumulation Period Length (determined as described below) is less than 12
months, the date on which the Accumulation Period actually commences may, at
the option of the Servicer, upon written notice to the Trustee, be delayed to
the first Business Day of the month that is the number of months prior to the
Class A Scheduled Payment Date at least equal to the Accumulation Period Length
and, as a result, the number of Monthly Periods in the Accumulation Period will

and to the Class B Certificateholders from the Distribution Account the amount

                  (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 Excess Collateral Amount
will be reduced by the amount of such excess, but not more than the Excess
Collateral 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 Excess Collateral Amount to be a negative number, the
Excess Collateral Amount will be reduced to zero, and the Class B Invested
Amount will be reduced by the amount by which the Excess Collateral 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 Amount.  If


                                       47

<PAGE>   52



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 Excess Collateral 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 Excess Collateral 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 Excess
Collateral Amount to be a negative number, the Excess Collateral Amount shall
be reduced to zero and the Class B Invested Amount shall be reduced by the
amount by which the Excess Collateral 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 Excess Collateral 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 Excess Collateral Default Amount. If on any Distribution Date, the Excess
Collateral 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, the Excess
Collateral 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 Excess Collateral Amount for such Distribution Date
(an "Excess Collateral Charge-Off"). The Excess Collateral 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


                                       48

Excess Collateral 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 Excess Collateral Amount
will thereafter be reimbursed (but not by an amount in excess of the unpaid
principal balance of the Excess Collateral Amount) 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.

Monthly Period, to make the following distributions in the following priority:

                  (a) an amount equal to the Class A Required Amount, if any,
with respect to the related Monthly Period will be used to fund the Class A
Required Amount and be applied in accordance with subsection 4.09(a) of the
Agreement;

                  (b) an amount equal to the aggregate amount of Class A
Investor Charge-Offs, which have not been previously reimbursed (after giving
effect to the allocation with respect to the related Distribution Date of
certain other amounts applied for that purpose) will be distributed to the
Holder of the Exchangeable Transferor Certificate on Transfer Dates with
respect to the Revolving Period, but not exceeding the Transferor Interest in
Principal Receivables on such day (after giving effect to any new Principal
Receivables 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 with respect to the Class B Outstanding Principal Balance at the
applicable Class B Certificate Rate but has not been deposited in the
Distribution Account for the benefit of the Class B Certificateholders either
on such Transfer Date or on a prior Transfer Date and any other amounts due and
owing on the related Distribution Date pursuant to subsection 4.09(b)(i) of the

Class B Certificateholders;

                  (d) an amount equal to the aggregate Class B Investor Default
Amount, if any, for the related Distribution Date will be distributed to the
holder of the Exchangeable Transferor Certificate on Transfer Dates with
respect to the Revolving Period (but not exceeding the Transferor Interest in
Principal Receivables on such day (after giving effect to any new Principal
Receivables 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;

                  (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
Receivables 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;

                  (f) an amount equal to the Excess Collateral Minimum Monthly
Interest for such Transfer Date, plus the amount of any Excess Collateral
Minimum Monthly Interest previously due but not paid to the Excess Collateral
Holders on a prior Transfer Date will be paid to the Excess Collateral Holders
in accordance with subsection 5.01(c) of the Agreement;

                  (g) an amount equal to the Unpaid Investor Monthly Servicing
Fee, with respect to the related Distribution Date, will be paid to the
Servicer;

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;

                  (i) an amount equal to the aggregate amount by which the
Excess Collateral Amount has been reduced below the Excess Collateral Initial
Amount for reasons other than the payment of principal to the Excess Collateral
Holders (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
Receivables 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;

                  (j) on each Transfer Date from and after the Reserve Account
Funding Date, but prior to the date on which the Reserve Account terminates as
described in subsection 4.17(f) of the Agreement, an amount up to the excess, if
any, of the Required Reserve Account Amount over the Available Reserve Account
Amount shall be deposited into the Reserve Account; and

                  (k) the balance, if any, after giving effect to the payments
made pursuant to subparagraphs (a) through (j) above shall be paid to the Excess

                  (a) On each Distribution Date, the Servicer will apply or
cause the Trustee to apply an amount, not to exceed the Excess Collateral
Amount, equal to the product of (a) (i) during the Revolving Period, the Excess
Collateral Floating Allocation Percentage or (ii) during an

         shall be applied in priority first pursuant to subsections 4.09(a)(i)
         through (iii) of the Agreement and then pursuant to subsections
         4.09(b)(i) and (ii) and 4.13(c) and (d) of the Agreement; and

                           (ii) any such collections not applied in the

         Collateral Principal Collections) will, on Distribution Dates with
         respect to the Revolving Period, be applied as Available Investor

                  On each Distribution Date the Excess Collateral Amount shall
be reduced by the amount of Reallocated Excess Collateral Principal Collections

Distribution Date. In the event that such reduction would cause the Excess
Collateral Amount to be a negative number, the Excess Collateral Amount shall
be reduced to zero and the Class B Invested Amount shall be reduced by the
amount by which the Excess Collateral Amount would have been reduced below zero.
In the event that the reallocation of Collections of Principal Receivables
would cause the Class B Invested Amount to be a negative number on any
Distribution Date, Collections of Principal Receivables shall be reallocated on
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.

determine LIBOR on the basis of the rate for deposits in United States dollars
for a one-month period which appears on Telerate Page 3750 as of 11:00 a.m.,
London time, on such date. If such rate does not appear on 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 one-month period. The Trustee shall
request the principal London office of each of the Reference Banks to provide a
quotation of its rate. If at least two such quotations are provided, the rate
for that LIBOR Determination Date shall be the arithmetic mean of the
quotations. If fewer than two quotations are provided as requested, the rate for
that LIBOR Determination Date will be the arithmetic mean of the rates quoted by
major banks in New York City, selected by the Servicer, at approximately 11:00
a.m., New York City time, on that day for loans in United States dollars to
leading European banks for a one-month period.

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 "Principal Funding Account"), bearing a designation clearly indicating that
      -------------------------
the funds deposited therein are held for the benefit of the Investor
Certificateholders. The Trustee shall possess all right, title and interest in
all funds on deposit from time to time in the Principal Funding Account and in
all proceeds thereof. The Principal Funding Account shall be under the sole
dominion and control of the Trustee for the benefit of the Investor
Certificateholders. If any time the institution holding the Principal Funding
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
transfer any cash or any investments to

Servicer, shall (i) make withdrawals from the Principal Funding Account from
time to time, in the amounts and for the purposes set forth in this Supplement,
and (ii) on each Transfer Date (from and after the commencement of the
Accumulation Period) prior to termination of the Principal Funding Account make
a deposit into the Principal Funding Account in the amount specified in, and
otherwise in accordance with, subsection 4.09(e) of the Agreement.

                  (b) Funds on deposit in the Principal Funding Account shall be
invested at the written direction of the Servicer by the Trustee in Permitted
Investments. Funds on deposit in the Principal Funding Account on any Transfer
Date, after giving effect to any withdrawals from the Principal Funding Account
on such Transfer Date, shall be invested in such investments that will mature so
that such funds will be 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 the Transfer Date occurring in the month following the
commencement of the Accumulation Period and on each Transfer Date thereafter
with respect to the Accumulation Period, the Trustee, acting at the Servicer's
written direction given on such Transfer Date, shall (x) transfer from the
Principal Funding Account to the Finance Charge Account the Principal Funding
Investment Proceeds on deposit in the Principal Funding Account, but not in
excess of the Covered Amount, for application as Class A Available Funds, Class
B Available Funds and Excess Collateral Available Funds pursuant to subsections
4.09(a), 4.09(b) and 4.09(c), respectively, of the Agreement and (y) pay any
excess Principal Funding Investment Proceeds to the Excess Collateral Holders.
An amount equal to any Principal Funding Investment Shortfall will be deposited
in the Finance Charge Account on each Transfer Date from the Reserve Account to
the extent funds are available pursuant to subsections 4.17(d), 4.17(e) and
4.17(f) of the Agreement. Principal Funding Investment Proceeds (including
reinvested interest) shall not be considered part of the amounts on deposit in

                  Section 4.17 Reserve Account.
                               ---------------

                  (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
      ---------------
deposited therein are held for the benefit of the Investor Certificateholders.
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
the benefit of the Investor Certificateholders. If at any time the institution
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) prior to termination of the Reserve Account make a deposit into
the Reserve Account in the amount specified in, and otherwise in accordance
with, subsection 4.13(j) of the Agreement.

                  (b) Funds on deposit in the Reserve Account shall be invested
at the written direction of the Servicer by the Trustee in Permitted
Investments. Funds on deposit in the Reserve Account on any Transfer Date, after
giving effect to any withdrawals from the Reserve Account on such Transfer Date,
shall be invested in such investments that will mature so that such funds will
be 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


                                       56

<PAGE>   61



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 Shortfall with respect to each Transfer Date with respect to
the Accumulation Period or the first Transfer Date with respect to the Rapid
Amortization Period; provided, however, that such amount will be reduced to the
                     --------  -------
extent that funds 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 than zero, the
Trustee, acting in accordance with the written instructions of 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 in
accordance with Section 4.09 of the Agreement.

                  (f) Upon the earliest to occur of (i) the termination of the
Trust pursuant to Article XII of the


                                       57

commenced, the occurrence of a Pay Out Event with respect to Series 1999-1 and
(iv) if the Accumulation Period has commenced, the earlier of the first Transfer
Date with respect to the Rapid Amortization Period and the Class A Scheduled 
Payment Date, the Trustee, acting in accordance with the written instructions of
the Servicer, after the prior payment of all amounts owing to the Series 1999-1
Certificateholders that are payable from the Reserve Account as provided herein,
shall withdraw from the Reserve Account and deposit in the Finance Charge
Account all amounts, if any, on deposit in the Reserve Account for application
in accordance with Section 4.09 of the Agreement, and the Reserve Account shall
be deemed to have terminated for purposes of this Supplement.

regulation there under, including, without limitation, an over-the-counter-
market or an interdealer quotation system that regularly disseminates firm buy
or sell quotations. In addition, any Assignee shall certify, prior to any
delivery or Transfer to it of any Excess Collateral that it is not and will not
become, for so long as it holds an interest in the Excess Collateral, a
partnership, Subchapter S corporation or grantor trust for U.S. federal income
tax purposes or, if it is such a Person, the Excess Collateral will represent
not more than 50% of the value of all of its assets. Each Initial Purchaser of
an interest in the Excess Collateral acknowledges that the Opinion of Counsel to
the effect that the Trust will not be treated as a publicly traded partnership
taxable as a corporation is dependent in part on the accuracy of its
certifications described in this subsection 11(c). For purposes of this Section
11, "Initial Purchaser" shall mean the Transferor, Bankers Trust (Delaware), not
in its individual capacity but solely in its capacity as owner trustee of the
First USA Secured Note Trust 1999-1 and The Bank of New York, not in its
individual capacity but solely in its capacity as indenture trustee for the
First USA Secured Note Trust 1999-1.

                  (d) Each Initial Purchaser of any interest in the Excess
Collateral shall, by its acceptance of the Excess Collateral, be deemed to have
certified and each Assignee shall certify to the Transferor, the Servicer and
the Trustee (i) that it has purchased its interest in the Excess Collateral for
investment only and not with a view to any public distribution thereof, (ii)
that it will not


                                       66
<PAGE>   71



offer, sell, pledge or otherwise transfer its interest in all or any portion of
the Excess Collateral, except in compliance with the Securities Act and other
applicable laws and only (1) to the Transferor or (2) to a limited number of
institutional "accredited investors" (as defined in rule 501(a)(1), (2), (3) or
(7) under the Securities Act) and in a transaction exempt from the registration
requirements of the Securities Act (upon delivery of the documentation required
by the Pooling and Servicing Agreement and, if the Trustee so requires, an
opinion of counsel satisfactory to the Trustee) and (iii) its purchase of its
interest in the Excess Collateral is not being made in reliance on the
Prospectus. No Excess Collateral Holders will have the right to require the
Transferor to register the Excess Collateral or any other securities under the
Securities Act or any other securities laws. Each holder by accepting a
beneficial interest in the Excess Collateral is deemed to represent that it is
an institutional "accredited investor" (as defined in rule 501(a)(1), (2), (3)
or (7) under the Securities Act).

                  (e) Any request for registration of transfer of all or any
portion of the Excess Collateral shall be made at the office of the Transfer
Agent and Registrar and shall be accompanied by a letter of representations from
the prospective Excess Collateral Holders substantially in the form attached as
Exhibit F, executed by the ultimate beneficial purchaser of the Excess
Collateral Amount (or any portion thereof) in person or by such prospective
Excess Collateral Holder's attorney thereunto duly authorized in writing, and
receipt by the Trustee of the writ ten consent of each of the Transferor and the
Servicer to such transfer, the Excess Collateral (or such portion thereof) shall
be transferred upon the Certificate Register. Such transfers of all or any
portion of the Excess Collateral shall be subject to the restrictions set forth
in this Section 11 and to such other restrictions as shall be set forth in the
letter of representations, substantially in the form attached as Exhibit F,
executed by the purchasing Excess Collateral Holder. Successive registrations
and registrations of transfers as aforesaid may be made from time to time as
desired, and each such registration shall be noted on the Certificate Register.

                  (f) No portion of the Excess Collateral or any interest
therein may be Transferred (including in the initial offering) to (a) an
"employee benefit plan" (as defined in Section 3(3) of ERISA), including
governmental


                                       67
<PAGE>   72



plans and church plans, (b) any "plan" (as defined in Section 4975(e)(1) of the
Code) including individual retirement accounts and Keogh plans, or (c) any other
entity whose underlying assets include "plan assets" (within the meaning of
Department of Labor Regulation Section 2510.3-101, 29 C.F.R. ss. 2510.3-101 or
otherwise under ERISA) by reason of a plan's investment in the entity,
including, without limitation, an insurance company general account.

                  (g) The Transferor and the Servicer will facilitate any
transfer of the Excess Collateral consistent with the requirements of this
Section 11, including assisting in the determination as to whether the number
of Targeted Holders would exceed ninety-nine.

                  SECTION 12. Compliance with Withholding Requirements.
                              ----------------------------------------
Notwithstanding any other provision of the Agreement, the Trustee and any Paying
Agent shall comply with all Federal withholding requirements with respect to
payments to the Excess Collateral Holders of interest, original issue discount,
or other amounts that the Trustee, any Paying Agent, the Servicer or the
Transferor reasonably believes are applicable under the Code. The consent of the
Excess Collateral Holders shall not be required for any such withholding. In the
event the Trustee or the Paying Agent withholds any amount from payments made to
any Excess Collateral Holders pursuant to federal withholding requirements, the
Trustee or the Paying Agent shall indicate to such Excess Collateral Holders the
amount withheld and all such amounts shall be deemed to have been paid to such
Excess Collateral Holder and the Excess Collateral Holders shall have no claim
therefor.

                  SECTION 13. Tax Characterization of the Excess Collateral. It
                              ---------------------------------------------
is the intention of the parties hereto that the provisions of Section 3.07 of
the Agreement shall not apply to cause the Excess Collateral to be treated as
debt for Federal, state and local income and franchise tax purposes, but rather
it is the intention of the parties hereto that Excess Collateral be treated for
Federal, state and local income and franchise tax purposes as an equity interest
in the assets of the Trust. In the event that the Excess Collateral is not so
treated, it is the intention of the parties that the Excess Collateral be
treated as an interest in a partnership that owns the Receivables.

            FIRST USA CREDIT CARD MASTER TRUST CLASS A FLOATING RATE
                     ASSET BACKED CERTIFICATE, SERIES 1999-1

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, N.A. (the "Bank").

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

                                          This certifies that CEDE & CO. (the 
"Certificateholder") is the registered owner of a fractional undivided interest

"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 1999-1 Supplement (the "Series 1999-1
Supplement"), dated as of February 24, 1999, 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 1999-1 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 1999-1" (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 Certifi-


<PAGE>   79
cates, Series 1999-1 (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, 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 Excess Collateral, Series
1999-1 (the "Excess Collateral") (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 Excess Collateral,
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 Excess Collateral (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 $1,000,000,000.
The Class A Invested Amount for any monthly Distribution Date will be an amount
equal to $1,000,000,000, 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 5.08813% per annum on the Class A Initial Invested Amount from February
24, 1999 through March 18, 1999, and for each Interest Period thereafter, the
Class A Certificates will bear interest at a per annum rate


<PAGE>   80



of 0.15% 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 be distributed to the extent of available
funds on March 19, 1999, and on the nineteenth 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 1999-1 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 March 19, 1999 and on each Distribution
Date thereafter until the Scheduled Series 1999-1 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 Excess Collateral Floating Allocation Percentage
of Collections of Principal Receivables will be applied first as Reallocated
Princi-


<PAGE>   81
pal 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 1999-1 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



<PAGE>   82



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
Excess Collateral Adjusted 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 Excess Collateral
Holders on the Excess Collateral 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 Excess Collateral
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 February 2004 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 Excess Collateral Amount have been



<PAGE>   83



paid in full and (ii) the Scheduled Series 1999-1 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 Excess Collateral Holders, 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 October 19, 2006 (or if such day
is not a Business Day, the next succeeding Business Day) (the "Scheduled Series
1999-1 Termination Date"). After the Scheduled Series 1999-1 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



<PAGE>   84



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 1999-1 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 1999-1 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.

            FIRST USA CREDIT CARD MASTER TRUST CLASS B FLOATING RATE
                     ASSET BACKED CERTIFICATE, SERIES 1999-1

Evidencing an undivided interest in a trust, the corpus of which consists of

                  (Not an interest in or a recourse obligation

constituting the Trust and all proceeds of the foregoing.

                          Although a summary of certain provisions of the
Agreement is set forth below, this Class B 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 B Floating Rate Asset Backed
Certificates, Series 1999-1" (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 1999-1 (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 Certifi-


                                      B-3
<PAGE>   89
cates, the holders of the Class B Certificates and the holders of the First USA
Credit Card Master Trust Excess Collateral, Series 1999-1 (the "Excess
Collateral Holders") (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 Excess Collateral, 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 Excess Collateral (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 B Initial Invested Amount is $90,361,000.
The Class B Invested Amount for any monthly Distribution Date will be an amount
equal to (i) $90,361,000, 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 Excess Collateral 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 5.33813% per annum on the Class B Initial Invested Amount from February
24, 1999 through March 18, 1999 and for each Interest Period thereafter, the
Class B Certificates will bear interest


                                       B-4

<PAGE>   90



at a per annum rate of 0.40% 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 March 19, 1999, and on the nineteenth day of each
month there after, or if such day is not a Business Day, the next succeeding
Business Day until the earlier of the day on which the Class B Invested Amount
is paid in full and the Scheduled Series 1999-1 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 Collections
of Finance Charge Receivables and, in certain circumstances, from Reallocated
Principal Collections on March 19, 1999 and on each Distribution Date thereafter
until the Scheduled Series 1999-1 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 Percent age 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 Percent
age 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 Alloca-


                                      B-5
<PAGE>   91

tion Percentage of Collections of Principal Receivables and the Excess
Collateral 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 1999-1 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


                                       B-6

<PAGE>   92



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 Excess Collateral Adjusted 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 Excess Collateral Holders on the Excess Collateral 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 Excess Collateral 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 February 2004 Distribution Date if the Class A
Invested Amount is paid in full, Available Investor Principal Collections and 
Excess Principal Collections allocable to Series 1999-1 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 1999-1 are insufficient to pay in full the Class B Invested Amount on the
February 2004 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, se-


                                      B-7

quentially, 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 Excess Collateral Amount have been paid in full and (ii) the Scheduled
Series 1999-1 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 Excess Collateral Holders, 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 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


                                       B-8

<PAGE>   94



Certificates will be paid to the Class B Certificateholders on the February 2004
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 October 19, 2006 (or if such day
is not a Business Day, the next succeeding Business Day) (the "Scheduled Series
1999-1 Termination Date"). After the Series 1999-1 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 1999-1 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 1999-1 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.

will furnish written notice of the substance of such amendment to each Class B
Certificateholder.

                                   [Issue Description]


Ladies and Gentlemen:

     This letter sets forth our understanding with respect to certain matters 
relating to the above-referenced issue (the "Securities"). Agent will act as
trustee, paying agent, fiscal agent, or other such agent of Issuer with respect
to the Securities pursuant to a trust indenture, trust agreement, or other
such document dated as of September 1, 1992* (the "Document"). First Chicago
                          -----------------                    -------------  
Capital Markets, Inc.** 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
Agent make the following representations to DTC:

     1. Prior to closing on the Securities on February 24, 1999 there shall be
                                              ----------------- 
deposited with DTC one Security certificate registered in the name of DTC's
nominee, Cede & Co., for each 

*    As supplemented as of February 24, 1999

**   As Representative for itself, Bear, Stearns & Co. Inc, Credit Suisse First 
     Boston Corporation, Morgan Stanley & Co. Incorporated and Salomon Smith 
     Barney Inc.

<PAGE>   99
stated maturity of the Securities in the face amounts set forth on Schedule A
hereto, the total of which represents 100% of the principal amounts 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. Issuer: (a) understands that DTC has no obligations 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.

     3. In the event of any solicitation of consents from or voting by holders
of the Securities, Issuer or Agent shall establish a record date for such
purposes (with no provisions for revocation of consents or votes by subsequent
holders) and shall, to the extent possible, 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 5.

     4. In the event of a full or partial redemption, Issuer or Agent 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 Agent
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

<PAGE>   100
     5. In the event of an invitation to tender the Securities (including
mandatory tenders, exchanges, and capital changes), notice by Issuer or Agent 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 or (212) 709-1094, and receipt of such notices
shall be confirmed by telephoning (212) 709-6884. Notices to DTC pursuant to
the above by mail or by any other means shall be sent to:

                              Manager; Reorganization Department
                              Reorganization Window

                              New York, NY 10004-2695

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

     7. Issuer or Agent 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 to 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 Agent 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

     8. [Note: ISSUER MUST REPRESENT ONE OF THE FOLLOWING, AND CROSS OUT THE
OTHER:] [The interest accrual period is payment date to payment date.]

     9. Issuer or Agent shall provide a written notice of interest payment
information to a standard interest announcement service subscribed to by DTC as
soon as the information is available. In the unlikely event that no such
service exists, Issuer or Agent shall provide such notice directly to DTC
electronically, as previously arranged by Issuer or Agent and DTC, as soon as
the information is available. If electronic transmission is not available,
absent any other arrangements between Issuer or Agent and DTC, such information
should be sent by telecopy to DTC's Dividend Department at (212) 709-1723 or
(212) 709-1686, and receipt for such notices shall be confirmed by telephoning
(212) 709-1270. Notices to DTC pursuant to the above by mail or by any other

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

     15. In the event of a redemption, acceleration, or any other similar
transaction (e.g., tender made and accepted in response to Issuer's or Agent'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 Agent 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 Agent prior to payment, if required.

     16. In the event that Issuer determines that beneficial owners of
Securities shall be able to obtain certificated Securities, Issuer or Agent
shall notify DTC of the availability of certificates. In
<PAGE>   102
such event, Issuer or Agent shall issue, transfer, and exchange certificates in
appropriate amounts, as required by DTC and others.

     17. 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 (at which time DTC will confirm with Issuer or Agent the
aggregate principal amount of Securities outstanding). Under such
circumstances, at DTC's request Issuer and Agent shall cooperate fully with DTC
by taking appropriate action to make available one or more separate certificates
evidencing Securities to any DTC Participant having Securities credited to its
DTC accounts.

     18. Nothing herein shall be deemed to require Agent to advance funds on
behalf of Issuer.

     19. This Letter of Representations may be executed in any number of
counterparts, each of which when so executed shall be deemed to be an original,
but all such counterparts together shall constitute but one and the same
instrument.

     20. This Letter of Representations is governed by, and shall be construed
in accordance with, the laws of the State of New York.

                                                                      ----------

                       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 DTC. 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.]
<PAGE>   106
     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 Cede
& Co., as nominee of DTC. DTC's practice is to credit Direct Participants'
accounts, upon DTC's receipt of funds and corresponding detail information from
Issuer or Agent, on payable date in accordance with their respective holdings
shown on DTC's records. 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, Agent, or Issuer, subject to any statutory or regulatory requirements as
may be in effect from time to time. Payment of principal and interest to Cede &
Co. is the responsibility of Issuer or Agent, 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 Agent [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 Agent [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 Agent [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.

     The Security certificate(s) shall remain in Agent's custody as a "Balance

Custodian ("DWAC") system to increase the Participant's account by a specified
number of shares, units, or obligations (a "Deposit Instruction"). Agent shall,

     Issuer and Agent recognize that DTC does not in any way undertake to, and
shall not have any responsibility to, monitor or ascertain whether a transfer
of Securities could give rise to a transaction prohibited or not otherwise
permissible under the Employee Retirement Income Security Act of 1974 or under
Section 4975 of the Internal Revenue Code of 1986. Issuer and Agent acknowledge
that: a) so long as Cede & Co. is the sole record owner of the Securities, it
shall be entitled to all voting rights in respect thereof and to receive the
full amount of all principal, premium, if any, and interest payable with
respect thereto; and b) DTC shall treat any DTC Participant having Securities
credited to its DTC accounts as entitled to the full benefits of ownership of
such Securities even if the crediting of such Securities to the DTC accounts of
such Participant results from transfers or failures to transfer in violation of
such laws. (The treatment by DTC of the effects of the crediting by it of
Securities to the accounts of DTC Participants shall not affect the rights of
Issuer or purchasers, sellers, or holders of Securities against any DTC
Participant.)

Re:      Excess Collateral, Series 1999-1
         --------------------------------

Ladies and Gentlemen:

         In connection with our proposed purchase of $114,458,000 in principal
amount of First USA Credit Card Master Trust, Excess Collateral, Series 1999-1
(the "Excess Collateral"), we confirm that:

         1. We have received such information and documentation as we deem
necessary in order to make our investment decision. We understand that such
information and documentation speaks only as of its date and that the
information contained therein may not be correct or complete as of any time
subsequent to such date.

         2. We agree to be bound by the restrictions and conditions relating to
the Excess Collateral set forth in the Pooling and Servicing Agreement, dated as
of September 1, 1992, as amended and as supplemented by the Series 1999-1
Supplement dated as of February 24, 1999 (the "Series 1999-1 Supplement" and
together with the Pooling and Servicing Agreement, the "Pooling and Servicing
Agreement"), each by and between First USA Bank, N.A., as transferor and
servicer, and The Bank of New York (Delaware) and agree to be bound by, and not
to reoffer, resell, pledge or otherwise transfer (any such act, a "Transfer")
the Excess Collateral except in compliance with such restrictions and conditions
including but not limited to those in Section 11 of the Series 1999-1
Supplement.


                                       F-1

<PAGE>   128



         3. We understand that the Excess Collateral has not been and will not
be registered under the Securities Act of 1933, as amended (the "Securities
Act") or any state securities law and agree that the Excess Collateral may be
reoffered, resold, pledged or otherwise transferred only in compliance with the
Securities Act and other applicable laws and only (i) to the Transferor or (ii)
to a limited number of institutional "accredited investors" (as defined in Rule
501(a)(1), (2), (3) or (7) under the Securities Act) and in a transaction exempt
from the registration requirements of the Securities Act (upon delivery of the
documentation required by the Pooling and Servicing Agreement and, if the
Trustee so requires, an opinion of counsel satisfactory to the Trustee).

         4. We have neither acquired nor will we Transfer any Excess Collateral
we acquire (or any interest therein) or cause any Excess Collateral (or any
interest therein) to be marketed on or through an "established securities
market" within the meaning of Section 7704(b)(1) of the Internal Revenue Code of
1986, as amended (the "Code") and any treasury regulation thereunder, including,
without limitation, an over-the-counter-market or an interdealer quotation
system that regularly disseminates firm buy or sell quotations.

         5. We are not and will not become, for so long as we own any interest
in the Excess Collateral, a partnership, Subchapter S corporation or grantor
trust for United States federal income tax purposes or, if we are such a Person,
the Excess Collateral does not represent more than 50% of the value of all of
our assets.

         6. We are a person who is either (A)(i) a citizen or resident of the
United States, (ii) a corporation or other entity organized in or under the
laws of the United States or any political subdivision thereof or (iii) a
person not described in (i) or (ii) whose ownership of the Excess Collateral is
effectively connected with a such person's conduct of a trade or business
within the United States (within the meaning of the Code) or (B) an estate or
trust the income of which is includible in gross income for United States
federal income tax purposes. We agree that (a) if we are a person described in
clause (A)(i) or (A)(ii) above, we will furnish to the person from whom we are
acquiring an interest in the Excess Collateral, the Servicer and the Trustee, a
properly executed U.S. Internal Revenue Service Form W-9 and a new Form W-9, or
any successor applicable form, upon the expiration or obsolescence of any
previously delivered form or (b) if we are a person described in clause
(A)(iii)




                                       F-2


<PAGE>   129



above, we will furnish to the person from whom we are acquiring an interest in
the Excess Collateral, the Servicer and the Trustee, a properly executed U.S.
Internal Revenue Service Form 4224 and a new Form 4224, or any successor
applicable form, upon the expiration or obsolescence of any previously delivered
form (and, in each case, such other certifications, representations or opinions
of counsel as may be requested by the Trustee). We recognize that if we are a
tax-exempt entity, payments with respect to the Excess Collateral may constitute
unrelated business taxable income.

         7. We understand that a subsequent Transfer of the Excess Collateral
will be void if such Transfer would cause the number of Targeted Holders (as
defined in the Series 1999-1 Supplement) to exceed ninety nine.

         8. We understand that the opinion of tax counsel that the Trust is not
a publicly traded partnership taxable as a corporation is dependent in part on
the accuracy of the representations in paragraphs 4 and 5.

         9. We are an institutional "accredited investor" (as defined in Rule
501(a)(1), (2), (3), or (7) of Regulation D under the Securities Act) and have
such knowledge and experience in financial and business matters as to be capable
of evaluating the merits and risks of our investment in the Excess Collateral,
and we and any account for which we are acting are each able to bear the
economic risk of our or its investment.

         10. We are acquiring the Excess Collateral purchased by us for our own
account or for a single account (each of which is an institutional "accredited
investor") as to which we exercise sole investment discretion.

         11. We are not (a) an "employee benefit plan" (as defined in Section
3(3) of ERISA), including governmental plans and church plans, (b) a plan
described in Section 4975(e)(1) of the Internal Revenue Code of 1986, as amended
(the "Code") including individual retirement accounts and Keogh plans, or (c)
any other entity whose underlying assets include "plan assets" (as defined in
United States Department of Labor ("DOL") Regulation Section 2510.3-101, 29
C.F.R. Section 2510.3-101 or otherwise under ERISA) by reason of a plan's 
investment in the entity, including, without limitation, an insurance company
general account

         12. We understand that any purported Transfer of any Excess Collateral
Amount in contravention of the restrictions and



                                       F-3

<PAGE>   130


conditions in paragraphs 1 through 11 above (including any violation of the
representation in paragraph 5 by an investor who continues to hold an interest
in the Excess Collateral occurring any time after the Transfer in which it
acquired such Excess Collateral) shall be null and void and the purported
transferee shall not be recognized by the Trust or any other person as an Excess
Collateral Holder for any purpose.

         13. We further understand that, on any proposed resale, pledge or
transfer of any Excess Collateral, we will be required to furnish to the Trustee
and the Registrar, such certifications and other information as the Trustee or
the Registrar may reasonably require to confirm that the proposed sale complies
with the foregoing restrictions and with the restrictions and conditions of the
Excess Collateral and the Pooling and Servicing Agreement pursuant to which the
Excess Collateral were issued and we agree that if we determine to Transfer any
Excess Collateral, we will cause our proposed transferee to provide the
Transferor, the Servicer and the Trustee with a letter substantially in the form
of this letter. We further understand that Excess Collateral purchased by us
will bear a legend to the foregoing effect.

         14. The person signing this letter on behalf of the ultimate
beneficial purchaser of the Excess Collateral has been duly authorized by such
beneficial purchaser of the Excess Collateral to do so.

         You are entitled to rely upon this letter and are irrevocably
authorized to produce this letter or a copy hereof to any interested party in
any administrative or legal proceeding or official inquiry with respect to the
matters covered hereby.

                                     Very truly yours,

                                     [full legal name of purchaser]

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 Amount.  If


                                       47
<PAGE>   52


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 Excess Collateral 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 Excess Collateral 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 Excess
Collateral Amount to be a negative number, the Excess Collateral Amount shall
be reduced to zero and the Class B Invested Amount shall be reduced by the
amount by which the Excess Collateral 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 Excess Collateral 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 Excess Collateral Default Amount. If on any Distribution Date, the Excess
Collateral 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, the Excess
Collateral 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 Excess Collateral Amount for such Distribution Date
(an "Excess Collateral Charge-Off"). The Excess Collateral 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


                                       48
<PAGE>   53


Excess Collateral 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 Excess Collateral Amount
will thereafter be reimbursed (but not by an amount in excess of the unpaid
principal balance of the Excess Collateral Amount) 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.

Monthly Period, to make the following distributions in the following priority:

                  (a) an amount equal to the Class A Required Amount, if any,

Investor Charge-Offs, which have not been previously reimbursed (after giving
effect to the allocation with respect to the related Distribution Date of
certain other amounts applied for that purpose) will be distributed to the
Holder of the Exchangeable Transferor Certificate on Transfer Dates with
respect to the Revolving Period, but not exceeding the Transferor Interest in
Principal Receivables on such day (after giving effect to any new Principal
Receivables 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 with respect to the Class B Outstanding Principal Balance at the
applicable Class B Certificate Rate but has not been deposited in the
Distribution Account for the benefit of the Class B Certificateholders either
on such Transfer Date or on a prior Transfer Date and any other amounts due and
owing on the related Distribution Date pursuant to subsection 4.09(b)(i) of the

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
Receivables 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;

                  (f) an amount equal to the Excess Collateral Minimum Monthly
Interest for such Transfer Date, plus the amount of any Excess Collateral
Minimum Monthly Interest previously due but not paid to the Excess Collateral
Holders on a prior Transfer Date will be paid to the Excess Collateral Holders
in accordance with subsection 5.01(c) of the Agreement;

                  (g) an amount equal to the Unpaid Investor Monthly Servicing
Fee, with respect to the related Distribution Date, will be paid to the
Servicer;

Excess Collateral Amount has been reduced below the Excess Collateral Initial
Amount for reasons other than the payment of principal to the Excess Collateral
Holders (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
Receivables transferred to the Trust on such day) and on Transfer Dates with

related Distribution Date;

                  (j) on each Transfer Date from and after the Reserve Account
Funding Date, but prior to the date on which the Reserve Account terminates as
described in subsection 4.17(f) of the Agreement, an amount up to the excess, if
any, of the Required Reserve Account Amount over the Available Reserve Account

                  (a) On each Distribution Date, the Servicer will apply or
cause the Trustee to apply an amount, not to exceed the Excess Collateral
Amount, equal to the product of (a)(i) during the Revolving Period, the Excess
Collateral Floating Allocation Percentage or (ii) during an

                           (i) an amount equal to the sum of (x) the excess, if
         any, of the Class A Required Amount with respect to such related
         Monthly Period over the amount of Excess Finance Charge Collections
         with respect to such related Monthly Period and (y) the Class B
         Required Amount with respect to the related Monthly Period which amount
         shall be applied in priority first pursuant to subsections 4.09(a)(i)
         through (iii) of the Agreement and then pursuant to subsections
         4.09(b)(i) and (ii) and 4.13(c) and (d) of the Agreement; and

                           (ii) any such collections not applied in the
         foregoing manner (and therefore not constituting Reallocated Excess
         Collateral Principal Collections) will, on Distribution Dates with
         respect to the Revolving Period, be applied as Available Investor
         Principal Collections.

                  (b) On each Distribution Date, the Servicer will apply or
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

are called "Reallocated Class B Principal Collections"):
            -----------------------------------------

                           (i) an amount equal to the excess, if any, of the
         Class A Required Amount with respect to such related Monthly Period
         over the sum of (x) the amount of Excess Finance Charge Collections
         with respect to such related Monthly Period and (y) the amount of

         Principal Collections) will, on Distribution Dates with respect to the
         Revolving Period, be applied as Available Investor Principal
         Collections.

                  On each Distribution Date the Excess Collateral Amount shall
be reduced by the amount of Reallocated Excess Collateral 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 Excess
Collateral Amount to be a negative number, the Excess Collateral Amount shall
be reduced to zero and the Class B Invested Amount shall be reduced by the
amount by which the Excess Collateral Amount would have been reduced below zero.
In the event that the reallocation of Collections of Principal Receivables
would cause the Class B Invested Amount to be a negative number on any
Distribution Date, Collections of Principal Receivables shall be reallocated on
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.

determine LIBOR on the basis of the rate for deposits in United States dollars
for a one-month period which appears on Telerate Page 3750 as of 11:00 a.m.,
London time, on such date. If such rate does not appear on 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 one-month period. The Trustee shall
request the principal London office of each of the Reference Banks to provide a
quotation of its rate. If at least two such quotations are provided, the rate
for that LIBOR Determination Date shall be the arithmetic mean of the 
quotations. If fewer than two quotations are provided as requested, the rate for
that LIBOR Determination Date will be the arithmetic mean of the rates quoted by
major banks in New York City, selected by the Servicer, at approximately 11:00
a.m., New York City time, on that day for loans in United States dollars to
leading European banks for a one-month period.

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

                  (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 "Principal Funding Account"), bearing a designation clearly indicating that
      -------------------------
the funds deposited therein are held for the benefit of the Investor
Certificateholders. The Trustee shall possess all right, title and interest in
all funds on deposit from time to time in the Principal Funding Account and in
all proceeds thereof. The Principal Funding Account shall be under the sole
dominion and control of the Trustee for the benefit of the Investor
Certificateholders. If any time the institution holding the Principal Funding
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
transfer any cash or any investments to such new Principal Funding Account. The

                  (b) Funds on deposit in the Principal Funding Account shall be

Date, after giving effect to any withdrawals from the Principal Funding Account
on such Transfer Date, shall be invested in such investments that will mature so
that such funds will be 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 the Transfer Date occurring in the month following the

B Available Funds and Excess Collateral Available Funds pursuant to subsections
4.09(a), 4.09(b) and 4.09(c), respectively, of the Agreement and (y) pay any
excess Principal Funding Investment Proceeds to the Excess Collateral Holders.
An amount equal to any Principal Funding Investment Shortfall will be deposited
in the Finance Charge Account on each Transfer Date from the Reserve Account to
the extent funds are available pursuant to subsections 4.17(d), 4.17(e) and
4.17(f) of the Agreement. Principal Funding Investment Proceeds (including

                  Section 4.17  Reserve Account.
                                ---------------

                  (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
      ---------------
deposited therein are held for the benefit of the Investor Certificateholders.
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
the benefit of the Investor Certificateholders. If at any time the institution
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 be half) 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) prior to termination of the Reserve Account make a deposit into

Investments. Funds on deposit in the Reserve Account on any Transfer Date, after
giving effect to any withdrawals from the Reserve Account on such Transfer Date,

be 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


                                       56

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 Shortfall with respect to each Transfer Date with respect to
the Accumulation Period or the first Transfer Date with respect to the Rapid
Amortization Period; provided, however, that such amount will be reduced to the
                     --------  -------
extent that funds 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 than zero, the
Trustee, acting in accordance with the written instructions of 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 in
accordance with Section 4.09 of the Agreement.

                  (f) Upon the earliest to occur of (i) the termination of the
Trust pursuant to Article XII of the

Date with respect to the Rapid Amortization Period and the Class A Scheduled
Payment Date, the Trustee, acting in accordance with the written instructions of
the Servicer, after the prior payment of all amounts owing to the Series 1999-2
Certificateholders that are payable from the Reserve Account as provided herein,
shall withdraw from the Reserve Account and deposit in the Finance Charge
Account all amounts, if any, on deposit in the Reserve Account for application
in accordance with Section 4.09 of the Agreement, and the Reserve Account shall
be deemed to have terminated for purposes of this Supplement.

pursuant to Section 2.01 or 2.06 of the Agreement, (i) shall prove to have been
incorrect in any material respect when made or when delivered, which continues
to be incorrect in any material respect for a period of 60 days after the date
on which written notice of such failure, requiring the same to be remedied,
shall have been given to the Transferor by the Trustee, or to the Transferor and
the Trustee by the Holders of the Series 1999-2 Certificates evidencing
Undivided Interests aggregating more than 50% of the Invested Amount of this
Series 1999-2 and (ii) as a result of which the interests of the Series 1999-2

                  (c) the average Portfolio Yield for any three consecutive
Monthly Periods is less than the average Base Rate for such three consecutive
Monthly Periods;

Holders of Series 1999-2 Certificates evidencing Undivided Interests aggregating
more than 50% of the Invested Amount of this Series 1999-2 by notice then given
in writing to the Transferor and the Servicer (and to the Trustee if given by
the Certificateholders) may declare that a pay out event (a "Series 1999-2 Pay

Series 1999-2 Certificateholders immediately upon the occurrence of such event.

                  For purposes of Series 1999-2, the fifth sentence of
subsection 9.02(a) of the Agreement shall be amended to read in its entirety as
follows:

         "If, however, with respect to the portion of the Receivables allocable
         to any outstanding Series, the holders of more than 50% of the
         principal amount of the Class A Certificates and the Class B
         Certificates and in the case of the Excess Collateral Amount, holders
         of more than 50% of the principal amount of the Excess Collateral
         Amount as well as more than 50% of holders of interests in the right to
         receive interest payments in respect of the Excess Collateral Amount,
         instruct the Trustee not to sell the portion of the Receivables
         allocable to such Series, the Trust shall continue with respect to such
         Series pursuant to the terms of the Agreement and the Supplement."

                  SECTION 9. Series 1999-2 Termination. The right of the Series
                             -------------------------
1999-2 Certificateholders to receive payments from the Trust will terminate on
the first Business Day following the Series 1999-2 Termination Date.

                  SECTION 10. Periodic Finance Charges and Other Fees. The
                              ---------------------------------------
Transferor hereby agrees that, except as other wise required by any Requirement
of Law, or as is deemed by the Transferor to be necessary in order for the 
Transferor to maintain its credit card business, based upon a good faith
assessment by the Transferor, in its sole discretion, of the nature of the
competition in the credit card business, it shall not at any time reduce the
Periodic Finance Charges assessed on any Receivable or other fees on any
Account if, as a result of such reduction, the


                                       64

Transferor's reasonable expectation of the Portfolio Yield as of such date would
be less than the Base Rate.

                  SECTION 11. Transfers of Excess Collateral. (a) No portion of
                              ------------------------------
the Excess Collateral or any interest therein may be sold (including in the
initial offering), conveyed, assigned, hypothecated, pledged, participated, or
otherwise transferred (each, a "Transfer") except in accordance with this
                                --------
Section 11. No portion of the Excess Collateral or any interest therein may be
Transferred to any Person (other than Bankers Trust (Delaware), not in its
individual capacity but solely in its capacity as owner trustee of the First USA
Secured Note Trust 1999-2 and The Bank of New York, not in its individual
capacity but solely in its capacity as indenture trustee for the First USA
Secured Note Trust 1999-2) (each, an "Assignee"), unless the Assignee shall
                                      --------
have executed and delivered the certification referred to in subsection 11(e)
below. Any attempted Transfer that would cause the number of Targeted Holders to
exceed ninety-nine shall be void.

                  (b) Each Assignee shall certify to the Transferor, the
Servicer, and the Trustee that it is either (A)(i) a citizen or resident of the
U.S., (ii) a corporation, partnership or other entity organized in or under the
laws of the U.S. or any political subdivision thereof which, if such entity is a
tax-exempt entity, recognizes that payments with respect to the Excess
Collateral may constitute unrelated business taxable income or (iii) a Person
not described in (i) or (ii) whose ownership of any interest in the Excess
Collateral is effectively connected with the conduct of a trade or business
within the United States (within the meaning of the Code) or (B) an estate or
trust the income of which is includible in gross income for U.S. federal income
tax purposes. Each Assignee also shall agree that (a) if it is a person
described in clause (A)(i) or (A)(ii) above, it will furnish to the Person from
whom it is acquiring any interest in the Excess Collateral, the Servicer and the
Trustee, a properly executed U.S. Internal Revenue Service Form W-9 (and will
agree to furnish a new Form W-9, or any successor applicable form, upon the
expiration or obsolescence of any previously delivered form) or (b) if it is a
person described in clause (A)(iii) above, it will furnish to the person from
whom it is acquiring any interest in the Excess Collateral, the Servicer and the
Trustee, a properly executed U.S. Internal Revenue Service Form 4224 (and


                                       65
<PAGE>   70


will agree to furnish a new Form 4224, or any successor applicable form, upon
the expiration or obsolescence of any previously delivered form and comparable
statements in accordance with applicable U.S. laws), and, in each case, such
other certifications, representations or opinions of counsel as may be requested
by the Trustee.

                  (c) Each Initial Purchaser of any interest in the Excess
Collateral and any Assignee thereof shall certify to the Transferor, the
Servicer and the Trustee that, in the case of any Assignee, it has not acquired
and, in the case of each Initial Purchaser and any Assignee, it will not sell,
trade or transfer any interest in the Excess Collateral or cause an interest in
the Excess Collateral to be marketed on or through an "established securities
market" within the meaning of Section 7704(b)(1) of the Code and any treasury
regulation thereunder, including, without limitation, an over-the-counter-
market or an interdealer quotation system that regularly disseminates firm buy
or sell quotations. In addition, any Assignee shall certify, prior to any
delivery or Transfer to it of any Excess Collateral that it is not and will not
become, for so long as it holds an interest in the Excess Collateral, a
partnership, Subchapter S corporation or grantor trust for U.S. federal income
tax purposes or, if it is such a Person, the Excess Collateral will represent
not more than 50% of the value of all of its assets. Each Initial Purchaser of
an interest in the Excess Collateral acknowledges that the Opinion of Counsel to
the effect that the Trust will not be treated as a publicly traded partnership
taxable as a corporation is dependent in part on the accuracy of its
certifications described in this subsection 11(c). For purposes of this Section
11, "Initial Purchaser" shall mean the Transferor, Bankers Trust (Delaware), not
in its individual capacity but solely in its capacity as owner trustee of the
First USA Secured Note Trust 1999-2 and The Bank of New York, not in its
individual capacity but solely in its capacity as indenture trustee for the
First USA Secured Note Trust 1999-2.

                  (d) Each Initial Purchaser of any interest in the Excess
Collateral shall, by its acceptance of the Excess Collateral, be deemed to have
certified and each Assignee shall certify to the Transferor, the Servicer and
the Trustee (i) that it has purchased its interest in the Excess Collateral for
investment only and not with a view to any public distribution thereof, (ii)
that it will not


                                       66
<PAGE>   71


offer, sell, pledge or otherwise transfer its interest in all or any portion of
the Excess Collateral, except in compliance with the Securities Act and other
applicable laws and only (1) to the Transferor or (2) to a limited number of
institutional "accredited investors" (as defined in rule 501(a)(1), (2), (3) or
(7) under the Securities Act) and in a transaction exempt from the registration
requirements of the Securities Act (upon delivery of the documentation required
by the Pooling and Servicing Agreement and, if the Trustee so requires, an
opinion of counsel satisfactory to the Trustee) and (iii) its purchase of its
interest in the Excess Collateral is not being made in reliance on the
Prospectus. No Excess Collateral Holders will have the right to require the
Transferor to register the Excess Collateral or any other securities under the
Securities Act or any other securities laws. Each holder by accepting a
beneficial interest in the Excess Collateral  is deemed to represent that it is
an institutional "accredited investor" (as defined in rule 501(a)(1), (2), (3)
or (7) under the Securities Act).

                  (e) Any request for registration of transfer of all or any
portion of the Excess Collateral shall be made at the office of the Transfer
Agent and Registrar and shall be accompanied by a letter of representations from
the prospective Excess Collateral Holders substantially in the form attached as
Exhibit F, executed by the ultimate beneficial purchaser of the Excess
Collateral Amount (or any portion thereof) in person or by such prospective
Excess Collateral Holder's attorney thereunto duly authorized in writing, and
receipt by the Trustee of the written consent of each of the Transferor and the
Servicer to such transfer, the Excess Collateral (or such portion thereof) shall
be transferred upon the Certificate Register. Such transfers of all or any
portion of the Excess Collateral shall be subject to the restrictions set forth
in this Section 11 and to such other restrictions as shall be set forth in the
letter of representations, substantially in the form attached as Exhibit F,
executed by the purchasing Excess Collateral Holder. Successive registrations
and registrations of transfers as aforesaid may be made from time to time as
desired, and each such registration shall be noted on the Certificate Register.

                  (f) No portion of the Excess Collateral or any interest
therein may be Transferred (including in the initial offering) to (a) an
"employee benefit plan" (as defined in Section 3(3) of ERISA), including
governmental


                                       67
<PAGE>   72


plans and church plans, (b) any "plan" (as defined in Section 4975(e)(1) of the
Code) including individual retirement accounts and Keogh plans, or (c) any other
entity whose underlying assets include "plan assets" (within the meaning of
Department of Labor Regulation Section 2510.3-101, 29 C.F.R. Sections 2510.3-101
or otherwise under ERISA) by reason of a plan's investment in the entity,
including, without limitation, an insurance company general account.

                  (g) The Transferor and the Servicer will facilitate any
transfer of the Excess Collateral consistent with the requirements of this
Section 11, including assisting in the determination as to whether the number
of Targeted Holders would exceed ninety-nine.

                  SECTION 12. Compliance with Withholding Requirements.
                              ----------------------------------------
Notwithstanding any other provision of the Agreement, the Trustee and any Paying
Agent shall comply with all Federal withholding requirements with respect to
payments to the Excess Collateral Holders of interest, original issue discount,
or other amounts that the Trustee, any Paying Agent, the Servicer or the
Transferor reasonably believes are applicable under the Code. The consent of the
Excess Collateral Holders shall not be required for any such withholding. In the
event the Trustee or the Paying Agent withholds any amount from payments made to
any Excess Collateral Holders pursuant to federal withholding requirements, the
Trustee or the Paying Agent shall indicate to such Excess Collateral Holders the
amount withheld and all such amounts shall be deemed to have been paid to such
Excess Collateral Holder and the Excess Collateral Holders shall have no claim
therefor.

                  SECTION 13. Tax Characterization of the Excess Collateral. It
                              ---------------------------------------------
is the intention of the parties hereto that the provisions of Section 3.07 of
the Agreement shall not apply to cause the Excess Collateral to be treated as
debt for Federal, state and local income and franchise tax purposes, but rather
it is the intention of the parties hereto that Excess Collateral be treated for
Federal, state and local income and franchise tax purposes as an equity interest
in the assets of the Trust. In the event that the Excess Collateral is not so
treated, it is the intention of the parties that the Excess Collateral be
treated as an interest in a partnership that owns the Receivables.

            FIRST USA CREDIT CARD MASTER TRUST CLASS A FLOATING RATE
                     ASSET BACKED CERTIFICATE, SERIES 1999-2

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, N.A. (the "Bank").

                  (Not an interest in or a recourse obligation
                of First USA Bank, N.A, 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

<PAGE>   78



(the "Trustee") of the Trust (the "Agreement"; such term to include any
Supplement or amendment thereto) as supplemented by the Series 1999-2 Supplement
(the "Series 1999-2 Supplement"), dated as of February 24, 1999, 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 1999-2 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 1999-2" (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,


<PAGE>   79


Series 1999-2 (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, 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 Excess Collateral, Series 1999-2 (the
"Excess Collateral") (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 Excess Collateral, 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 Excess Collateral (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 $500,000,000. The Class
A Invested Amount for any monthly Distribution Date will be an amount equal to
$500,000,000, 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
5.12813% per annum on the Class A Initial Invested Amount from February 24, 1999
through March 18, 1999, and for each Interest Period thereafter, the Class A
Certificates will bear interest at a per annum rate of 0.19% in


<PAGE>   80


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 be distributed to the extent of available funds on March
19, 1999, and on the nineteenth 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 1999-2 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 March 19, 1999 and on each Distribution Date thereafter until the
Scheduled Series 1999-2 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 Excess Collateral Floating Allocation Percentage
of Collections of Principal Receivables will be applied first as Reallocated
Principal


<PAGE>   81


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 1999-2 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


<PAGE>   82


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 Excess Collateral Adjusted 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
Excess Collateral Holders on the Excess Collateral 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 Excess Collateral 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 February 2006 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
Excess Collateral Amount have been paid in


<PAGE>   83


full and (ii) the Scheduled Series 1999-2 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 Excess Collateral Holders, 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 October 20, 2008 (or if such day is not a Business
Day, the next succeeding Business Day) (the "Scheduled Series 1999-2 Termination
Date"). After the Scheduled Series 1999-2 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


<PAGE>   84


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 1999-2 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 1999-2 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.

to be duly executed on this 24th day of February, 1999.

                     ASSET BACKED CERTIFICATE, SERIES 1999-2

Evidencing an undivided interest in a trust, the corpus of which consists of

                  (Not an interest in or a recourse obligation

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

1999-2 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 B 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 B Floating Rate Asset Backed Certificates,
Series 1999-2" (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 1999-2 (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


                                      B-3
<PAGE>   89



the Class B Certificates and the holders of the First USA Credit Card Master
Trust Excess Collateral, Series 1999-2 (the "Excess Collateral Holders") (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 Excess Collateral, 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 Excess Collateral (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 B Initial Invested Amount is $45,180,000. The Class
B Invested Amount for any monthly Distribution Date will be an amount equal to
(i) $45,180,000, 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 Excess Collateral 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
5.37813% per annum on the Class B Initial Invested Amount from February 24, 1999
through March 18, 1999 and for each Interest Period thereafter, the Class B
Certificates will bear interest at a per annum rate of

                                      B-4

<PAGE>   90


0.44% 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 March 19, 1999, and on the nineteenth 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 B Invested Amount is paid in full and the
Scheduled Series 1999-2 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 Collections of Finance Charge Receivables and, in
certain circumstances, from Reallocated Principal Collections on March 19, 1999
and on each Distribution Date thereafter until the Scheduled Series 1999-2
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 Excess

                                      B-5

<PAGE>   91


Collateral 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 1999-2 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

                                      B-6

<PAGE>   92


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 Excess Collateral Adjusted 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
Excess Collateral Holders on the Excess Collateral 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 Excess Collateral 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 February 2006 Distribution Date if the Class A Invested
Amount is paid in full, Available Investor Principal Collections and Excess
Principal Collections allocable to Series 1999-2 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
1999-2 are insufficient to pay in full the Class B Invested Amount on the
February 2006 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.

                                      B-7

<PAGE>   93


                  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
Excess Collateral Amount have been paid in full and (ii) the Scheduled Series
1999-2 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 Excess Collateral Holders, 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
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 February 2006 Distribution Date
and on each Distribution Date during the Rapid Amortization Period beginning
with the Class B Principal Commencement Date, and thereafter

                                      B-8

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 October 20, 2008 (or if such day is not a Business
Day, the next succeeding Business Day) (the "Scheduled Series 1999-2 Termination
Date"). After the Series 1999-2 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 certificate-
holders 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 1999-2 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 1999-2 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.

Ladies and Gentlemen:

     This letter sets forth our understanding with respect to certain matters 
relating to the above-referenced issue (the "Securities"). Agent will act as
trustee, paying agent, fiscal agent, or other such agent of Issuer with respect
to the Securities pursuant to a trust indenture, trust agreement, or other
such document dated as of September 1, 1992* (the "Document"). Credit Suisse
                          -----------     -                    -------------  
First Boston Corporation 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
Agent make the following representations to DTC:

     1. Prior to closing on the Securities on February 24, 1999, there shall be
                                              -----------     -
deposited with DTC one Security certificate registered in the name of DTC's
nominee, Cede & Co., for each 

*    As supplemented as of February 24, 1999

**   As Representative for itself, First Chicago Capital Markets, Inc., Lehman
     Brothers Inc., Merril Lynch, Pierce, Fenner & Smith Incorporated and
     Morgan Stanley & Co. Incorporated.
<PAGE>   98
stated maturity of the Securities in the face amounts set forth on Schedule A
hereto, the total of which represents 100% of the principal amounts 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. Issuer: (a) understands that DTC has no obligations 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.

     3. In the event of any solicitation of consents from or voting by holders
of the Securities, Issuer or Agent shall establish a record date for such
purposes (with no provisions for revocation of consents or votes by subsequent
holders) and shall, to the extent possible, 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 5.

     4. In the event of a full or partial redemption, Issuer or Agent 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 Agent
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:

such notice shall be sent to DTC by a secure means in the manner set forth in

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

     15. In the event of a redemption, acceleration, or any other similar
transaction (e.g., tender made and accepted in response to Issuer's or Agent'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 Agent 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 Agent prior to payment, if required.

     16. In the event that Issuer determines that beneficial owners of
Securities shall be able to obtain certificated Securities, Issuer or Agent
shall notify DTC of the availability of certificates. In
<PAGE>   101
such event, Issuer or Agent shall issue, transfer, and exchange certificates in
appropriate amounts, as required by DTC and others.

     17. 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 (at which time DTC will confirm with Issuer or Agent the
aggregate principal amount of Securities outstanding). Under such
circumstances, at DTC's request Issuer and Agent shall cooperate fully with DTC
by taking appropriate action to make available one or more separate certificates
evidencing Securities to any DTC Participant having Securities credited to its
DTC accounts.

     18. Nothing herein shall be deemed to require Agent to advance funds on
behalf of Issuer.

     19. This Letter of Representations may be executed in any number of
counterparts, each of which when so executed shall be deemed to be an original,
but all such counterparts together shall constitute but one and the same
instrument.

     20. This Letter of Representations is governed by, and shall be construed
in accordance with, the laws of the State of New York.

     21. The following riders, attached hereto, are hereby incorporated into

                       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 DTC. 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.]
<PAGE>   105
     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 Cede
& Co., as nominee of DTC. DTC's practice is to credit Direct Participants'
accounts, upon DTC's receipt of funds and corresponding detail information from
Issuer or Agent, on payable date in accordance with their respective holdings
shown on DTC's records. 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, Agent, or Issuer, subject to any statutory or regulatory requirements as
may be in effect from time to time. Payment of principal and interest to Cede &
Co. is the responsibility of Issuer or Agent, 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 Agent [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 Agent [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 Agent [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.

     Issuer and Agent recognize that DTC does not in any way undertake to, and
shall not have any responsibility to, monitor or ascertain whether a transfer
of Securities could give rise to a transaction prohibited or not otherwise
permissible under the Employee Retirement Income Security Act of 1974 or under
Section 4975 of the Internal Revenue Code of 1986. Issuer and Agent acknowledge
that: a) so long as Cede & Co. is the sole record owner of the Securities, it
shall be entitled to all voting rights in respect thereof and to receive the
full amount of all principal, premium, if any, and interest payable with
respect thereto; and b) DTC shall treat any DTC Participant having Securities
credited to its DTC accounts as entitled to the full benefits of ownership of
such Securities even if the crediting of such Securities to the DTC accounts of
such Participant results from transfers or failures to transfer in violation of
such laws. (The treatment by DTC of the effects of the crediting by it of
Securities to the accounts of DTC Participants shall not affect the rights of
Issuer or purchasers, sellers, or holders of Securities against any DTC
Participant.)

Re: Excess Collateral, Series 1999-2
    --------------------------------


Ladies and Gentlemen:

         In connection with our proposed purchase of $57,230,000 in principal
amount of First USA Credit Card Master Trust, Excess Collateral, Series 1999-2
(the "Excess Collateral"), we confirm that:

         1. We have received such information and documentation as we deem
necessary in order to make our investment decision. We understand that such
information and documentation speaks only as of its date and that the
information contained therein may not be correct or complete as of any time
subsequent to such date.

         2. We agree to be bound by the restrictions and conditions relating to
the Excess Collateral set forth in the Pooling and Servicing Agreement, dated as
of September 1, 1992, as amended and as supplemented by the Series 1999-2
Supplement dated as of February 24, 1999 (the "Series 1999-2 Supplement" and
together with the Pooling and Servicing Agreement, the "Pooling and Servicing
Agreement"), each by and between First USA Bank, N.A., as transferor and
servicer, and The Bank of New York (Delaware) and agree to be bound by, and not
to reoffer, resell, pledge or otherwise transfer (any such act, a "Transfer")
the Excess Collateral except in compliance with such restrictions and conditions
including but not limited to those in Section 11 of the Series 1999-2
Supplement.


                                       F-1

<PAGE>   127


         3. We understand that the Excess Collateral has not been and will not
be registered under the Securities Act of 1933, as amended (the "Securities
Act") or any state securities law and agree that the Excess Collateral may be
reoffered, resold, pledged or otherwise transferred only in compliance with the
Securities Act and other applicable laws and only (i) to the Transferor or (ii)
to a limited number of institutional "accredited investors" (as defined in Rule
501(a)(1), (2), (3) or (7) under the Securities Act) and in a transaction exempt
from the registration requirements of the Securities Act (upon delivery of the
documentation required by the Pooling and Servicing Agreement and, if the
Trustee so requires, an opinion of counsel satisfactory to the Trustee).

         4. We have neither acquired nor will we Transfer any Excess Collateral
we acquire (or any interest therein) or cause any Excess Collateral (or any
interest therein) to be marketed on or through an "established securities
market" within the meaning of Section 7704(b)(1) of the Internal Revenue Code of
1986, as amended (the "Code") and any treasury regulation thereunder, including,
without limitation, an over-the-counter-market or an interdealer quotation
system that regularly disseminates firm buy or sell quotations.

         5. We are not and will not become, for so long as we own any interest
in the Excess Collateral, a partnership, Subchapter S corporation or grantor
trust for United States federal income tax purposes or, if we are such a Person,
the Excess Collateral does not represent more than 50% of the value of all of
our assets.

         6. We are a person who is either (A)(i) a citizen or resident of the
United States, (ii) a corporation or other entity organized in or under the laws
of the United States or any political subdivision thereof or (iii) a person not
described in (i) or (ii) whose ownership of the Excess Collateral is effectively
connected with a such person's conduct of a trade or business within the United
States (within the meaning of the Code) or (B) an estate or trust the income of
which is includible in gross income for United States federal income tax
purposes. We agree that (a) if we are a person described in clause (A)(i) or
(A)(ii) above, we will furnish to the person from whom we are acquiring an
interest in the Excess Collateral, the Servicer and the Trustee, a properly
executed U.S. Internal Revenue Service Form W-9 and a new Form W-9, or any
successor applicable form, upon the expiration or obsolescence of any previously
delivered form or (b) if we are a person described in clause (A)(iii)

                                       F-2

<PAGE>   128


above, we will furnish to the person from whom we are acquiring an interest in
the Excess Collateral, the Servicer and the Trustee, a properly executed U.S.
Internal Revenue Service Form 4224 and a new Form 4224, or any successor
applicable form, upon the expiration or obsolescence of any previously delivered
form (and, in each case, such other certifications, representations or opinions
of counsel as may be requested by the Trustee). We recognize that if we are a
tax-exempt entity, payments with respect to the Excess Collateral may constitute
unrelated business taxable income.

         7. We understand that a subsequent Transfer of the Excess Collateral
will be void if such Transfer would cause the number of Targeted Holders (as
defined in the Series 1999-2 Supplement) to exceed ninety nine.

         8. We understand that the opinion of tax counsel that the Trust is not
a publicly traded partnership taxable as a corporation is dependent in part on
the accuracy of the representations in paragraphs 4 and 5.

         9. We are an institutional "accredited investor" (as defined in Rule
501(a)(1), (2), (3), or (7) of Regulation D under the Securities Act) and have
such knowledge and experience in financial and business matters as to be capable
of evaluating the merits and risks of our investment in the Excess Collateral,
and we and any account for which we are acting are each able to bear the
economic risk of our or its investment.

         10. We are acquiring the Excess Collateral purchased by us for our own
account or for a single account (each of which is an institutional "accredited
investor") as to which we exercise sole investment discretion.

         11. We are not (a) an "employee benefit plan" (as defined in Section
3(3) of ERISA), including governmental plans and church plans, (b) a plan
described in Section 4975(e)(1) of the Internal Revenue Code of 1986, as amended
(the "Code") including individual retirement accounts and Keogh plans, or (c)
any other entity whose underlying assets include "plan assets" (as defined in
United States Department of Labor ("DOL") Regulation Section 2510.3-101, 29
C.F.R. Sections 2510.3-101 or otherwise under ERISA) by reason of a plan's
investment in the entity, including, without limitation, an insurance company
general account

         12. We understand that any purported Transfer of any Excess Collateral
Amount in contravention of the restrictions and

                                       F-3

<PAGE>   129


conditions in paragraphs 1 through 11 above (including any violation of the
representation in paragraph 5 by an investor who continues to hold an interest
in the Excess Collateral occurring any time after the Transfer in which it
acquired such Excess Collateral) shall be null and void and the purported
transferee shall not be recognized by the Trust or any other person as an Excess
Collateral Holder for any purpose.

         13. We further understand that, on any proposed resale, pledge or
transfer of any Excess Collateral, we will be required to furnish to the Trustee
and the Registrar, such certifications and other information as the Trustee or
the Registrar may reasonably require to confirm that the proposed sale complies
with the foregoing restrictions and with the restrictions and conditions of the
Excess Collateral and the Pooling and Servicing Agreement pursuant to which the
Excess Collateral were issued and we agree that if we determine to Transfer any
Excess Collateral, we will cause our proposed transferee to provide the
Transferor, the Servicer and the Trustee with a letter substantially in the form
of this letter. We further understand that Excess Collateral purchased by us
will bear a legend to the foregoing effect.

         14. The person signing this letter on behalf of the ultimate beneficial
purchaser of the Excess Collateral has been duly authorized by such beneficial
purchaser of the Excess Collateral to do so.

         You are entitled to rely upon this letter and are irrevocably
authorized to produce this letter or a copy hereof to any interested party in
any administrative or legal proceeding or official inquiry with respect to the
matters covered hereby.

                                       Very truly yours,

                                       [full legal name of purchaser]
