                                   WITNESSETH

                  WHEREAS, the Seller and the Distributor are parties to the
Transfer Agreement (as defined in Appendix A hereto) pursuant to which from time
to time the Distributor shall sell and the Seller shall purchase certain
distribution fee receivables in accordance with the terms thereof;

                  WHEREAS, the Seller, the Purchaser and the Program Agent
previously entered into that certain Amended and Restated Purchase and Sale
Agreement dated as of December 22, 1997 (as amended and supplemented prior to
the date hereof, the "Existing Purchase Agreement"); and

                  WHEREAS, the parties hereto desire that the Existing Purchase
Agreement, the Distributor Undertaking and the Advisor Undertaking (as such
terms are defined in the Existing Purchase Agreement) be combined, amended and
restated as set forth herein;

                  NOW, THEREFORE, for good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the parties hereto,
intending to be legally bound, hereby agree as follows:

                                   ARTICLE I
                      DEFINITIONS AND RULES OF CONSTRUCTION

                  Section 1.01. Definitions.

                  Capitalized terms not otherwise defined herein shall have the
meanings assigned to such terms in the Definitions List attached hereto as
Appendix A.

                  Section 1.02. Rules of Construction.

                  For all purposes of this Agreement, except as otherwise
expressly provided or unless the context otherwise requires (a) each use in this
Agreement of a singular version of a pronoun shall be deemed to include
references to the plural, and vice versa, (b) Article and Section headings are
for convenience of reference only and shall not affect the construction of this
Agreement, and (c) references to "this section" or words of similar import shall

<PAGE>   6

refer to the entire section and not to a particular subsection, and references
to "hereunder", "herein" or words of similar import shall be deemed to refer to
this entire Agreement and not to the particular section or subsection.

                                   ARTICLE II
               PURCHASE AND SALE OF RECEIVABLES; ADDITIONAL FUNDS

                  Section 2.01. Purchase of Receivables.

                  On each Purchase Date and subject to and upon the terms and
conditions set forth in this Agreement, the Seller shall sell, transfer, convey
and assign to the Purchaser on and as of such Purchase Date, all of the Seller's
right, title and interest in, to and under the Receivables and the Collections
and Ancillary Rights in respect thereof relating to the sales of Shares (other
than Excluded Shares) of each Fund for the Purchase Period to which such
Purchase Date relates, and the Purchaser shall purchase from the Seller such
Receivables and Ancillary Rights in respect thereof and Collections for an
amount equal to the aggregate Purchase Prices payable in respect of such
Receivables. The Purchase Prices to be paid by the Purchaser on each Purchase
Date shall be paid in immediately available funds by wire transfer to the
Seller's Account. Notwithstanding anything in this Agreement to the contrary,
the Purchaser shall not purchase on any Purchase Date and the Seller shall not
sell to the Purchaser any Receivables relating to any Excluded Shares.

                  Section 2.02. Purchase Notices and Funding Notices.

                  With respect to the Receivables to be purchased on any
Purchase Date, the Seller shall transmit or shall cause to be transmitted to the
Program Agent (with a copy to the Collection Agent), not later than 10:00 a.m.
(New York City time) on such proposed Purchase Date, by facsimile transmission a
Purchase Notice. The Seller agrees that it shall deliver from time to time prior
to the Termination Date, but no less frequently than once each calendar month, a
Purchase Notice, sufficient to initiate the sale of the Receivables for the
period from the immediately preceding Sale Cutoff Date to the Sale Cutoff Date
specified in such Purchase Notice, which Sale Cutoff Date shall not be more than
five (5) Business Days prior to the proposed Purchase Date. The Seller shall
provide the Program Agent (with a copy to the Collection Agent) with a Funding
Notice for each Funding Period for which it is reasonably anticipated that the
Funding Amount for such Funding Period will not be sufficient to cover the
maximum aggregate Purchase Prices of Receivables to be purchased by the
Purchaser during such Funding Period, which Funding Notice shall specify the
amount of such deficiency and shall be delivered to the Program Agent three (3)
Business Days prior to such Funding Period. The Purchaser shall by wire transfer
remit the amount of any such deficiency specified in a Funding Notice to the
Purchaser's Funding Account.

                  Section 2.03. Additional Funds and Companies.

                  Unless an Event of Termination (or an event which, with the
passage of time or notice, or both, would constitute an Event of Termination)
shall have occurred and be continuing, the Seller may request that on the
applicable Addition Effective Date an Additional Eligible Fund become a "Fund"
under this Agreement and if such Additional Eligible Fund is not

                                       2
<PAGE>   7

a series of an existing "Company" under this Agreement the Seller may request
that the investment company of which such Additional Fund is a series becomes a
"Company" under this Agreement; provided, that such additional investment
company (the "Additional Company") is registered with the SEC under the
Investment Company Act. On and as of such Addition Effective Date, (i) each
Additional Eligible Fund and Additional Company shall become a Fund and a
Company, respectively, hereunder, (ii) the Servicing Agreement shall be deemed
to be supplemented to reflect such addition, (iii) Schedules II and IV hereto
shall be deemed to be supplemented to add the applicable information relating to
such Fund set forth in the Additional Eligible Fund Addendum relating to such
Additional Eligible Fund and (iv) any reference in this Agreement to any change
or modification since the date of this Agreement to the underwriting agreement,
distribution plan, advisory agreement, prospectus, the fundamental investment
objectives or contingent deferred sales charge arrangement in respect of such
Additional Eligible Fund shall be deemed to refer to any change or modification
thereof since such Addition Effective Date.

                  The term "Addition Effective Date" shall mean with respect to
any Additional Eligible Fund, the first date on which all of the following
conditions shall have been satisfied:

                  (i) the Program Agent shall have received a fully executed
                  Additional Eligible Fund Addendum, together with such signed
                  opinions of counsel to the applicable Company, the
                  Distributor, the Advisor and the Seller, each dated a date
                  reasonably near the Addition Effective Date, as the Program
                  Agent shall have reasonably requested, all in form, scope and
                  substance reasonably satisfactory to the Program Agent;
                  provided, however, that the Seller, the Advisor and the
                  Distributor will not be required to deliver a True Sale
                  opinion in connection with such addition;

                  (ii) the Program Agent shall have received such instruments,
                  certificates and documents regarding the addition of such
                  Additional Eligible Fund from the Distributor, the Seller, the
                  Advisor and the applicable Company, as the Program Agent shall
                  have reasonably requested; provided, however, that an
                  officer's certificate in the form of Exhibits B-1 and B-2
                  shall not be required;

                  (iii) the Program Agent and the Seller shall have agreed in
                  writing to any change in the Purchase Price Percentage
                  applicable to the Receivables relating to such Fund; and

                  (iv) the Program Agent shall have received evidence
                  satisfactory to it that (a) the conditions in respect of such
                  Additional Eligible Fund set forth in Section 3.01 of this
                  Agreement immediately after the Addition Effective Date shall
                  be satisfied, and (b) that on such Addition Effective Date the
                  Receivables relating to such Additional Eligible Fund shall
                  constitute Eligible Receivables.

                  (i) any Underwriting Agreement, any Distribution Plan, any
Advisory Agreement or any CDSC arrangement applicable to holders of Shares of
any Fund, in each case as in effect on the date of this Agreement (or as
hereafter modified, amended or supplemented with the consent of the Program
Agent), shall be terminated, no longer enforceable, or be otherwise ineffective,
in whole or in part, for any reason, whether voluntarily or involuntarily,
including without limitation by any Authority or as a result of any change in
Applicable Law, unless (x) in respect of the applicable Fund a replacement
Underwriting Agreement, Distribution Plan or Advisory Agreement, as the case may
be, has become effective and which has terms, in the reasonable opinion of the
Program Agent at least as favorable to the Distributor, the Advisor and the
Purchaser, as the Underwriting Agreement, the Distribution Plan or the Advisory
Agreement, as the case may be, each as in effect on the date of this Agreement
(or as hereafter modified, amended or supplemented with the consent of the
Program Agent), including, without limitation, in respect of the timing and
amount payable in respect of the Purchased Receivables relating to such Fund as
described in clause (h) above, and (y) no reasonable possibility of an Adverse
Effect shall arise as a result thereof; or

                  (j) except as a result of a Permitted Change in Control, the
Seller shall cease to own directly or indirectly a majority of the issued and
outstanding stock and a majority of the voting securities of the Distributor; or

                  (k) the Securities Investor Protection Corporation,
established under SIPA, shall have applied for a protective decree against the
Distributor and the Distributor shall have failed to obtain a dismissal of such
application within thirty (30) days after such application; or

                  (l) the SEC shall have revoked the broker/dealer registration
of the Distributor; or

                  (m) the Distributor shall have failed to meet the minimum
capital requirements prescribed from time to time by Rule 15c3-1 under the
Exchange Act and such failure is not cured within thirty (30) days after such
failure, it being understood that a determination by a relevant Authority shall
not be deemed conclusive evidence of such failure so long as the Distributor is
diligently contesting such determination in good faith by appropriate
proceedings; or

                  (n) the SEC or any other Authority shall have modified or
terminated or shall propose to modify, revoke, repeal or terminate Rule 12b-1 of
the Investment Company Act or the Conduct Rules in a manner which gives rise to
a reasonable possibility of an Adverse Effect; or

broker/dealer under the Exchange Act and with the NASD or the Advisor shall
cease to be registered as an investment advisor under the Investment Advisers
Act; or

                  (p) any Company, any Transfer Agent or any Sub-transfer Agent
shall fail to make or cause to be made in a timely manner any payment or deposit
required to be made under any Distribution Plan, Underwriting Agreement or any
Irrevocable Payment Instruction, or any Company or the Transfer Agent shall fail
to withhold from redemption proceeds paid to any holder of a Share any CDSCs
required to be withheld and remit such funds to the Demand

Deposit Account for further credit to the Collection Account in accordance with
any Irrevocable Payment Instruction and such failure shall continue for three
(3) Business Days, or any such Person shall be prevented by any Authority or by
any Applicable Law from doing so or any Company, the Transfer Agent or
Sub-transfer Agent shall so assert in writing; or

                  (q) each Company shall be required by any Authority or any
Applicable Law to suspend the sale of Shares of any Fund under circumstances
that gives rise to a reasonable possibility of an Adverse Effect; or

                  (r) each Company shall cease to regularly offer Shares of any
Fund to the public under circumstances that gives rise to a reasonable
possibility of an Adverse Effect; or

                  (s) except as a result of a Permitted Change in Control, A I M
Advisors, Inc. shall cease to act as the investment advisor of any Fund under
the applicable Advisory Agreement; or

                  (t) except as a result of a Permitted Change in Control or as
specifically consented to in writing by the Program Agent, the Seller, the
Advisor or the Distributor, as the case may be, shall (i) sell or otherwise
dispose of all or a substantial portion of its assets, other than as agreed to
in writing by the Program Agent, (ii) consolidate with or merge into any other
entity, or (iii) acquire all or substantially all of the assets of another
Person, unless the assets acquired are less than twenty-five percent (25%) of
the assets of the Seller, the Advisor or the Distributor, as the case may be;

then in respect of any occurrence of any such event, the Program Agent may in
respect of each such occurrence, by notice to the Seller to be given within
ninety (90) days of the Program Agent's receipt of notice of occurrence of each
such event, declare the Termination Date to have occurred (in which case the
Termination Date shall be deemed to have occurred); provided, that, upon the
occurrence of any event (without any requirement for the giving of notice)
described in subsection (f) or (k) of this Section 6.01, the Termination Date
shall be deemed to have automatically have occurred. Notwithstanding the
foregoing, if an Event of Termination shall have occurred as a result of a
breach of Section 4.01(k) or Section 5.01(t) and such breach relates solely to
the information prepared by a Sub-transfer Agent that constitutes an
Unaffiliated Agent (the "Affected Sub-transfer Agent"), then (i) the Purchaser
and the Program Agent, at the request of the Seller, hereby agree to negotiate
in good faith to amend this Agreement, the Collection Agency Agreement and the
Allocation Procedures to the extent necessary so as to permit the continued
purchase of Receivables which do not relate to such Affected Sub-transfer Agent,
and (ii) the Program Agent agrees that it shall not declare the Termination Date
to have occurred as a result of any such breach if either (A) the amendments
referred to in clause (i) above have been agreed upon by the Program Agent and
the Seller within thirty (30) days after the Seller has knowledge of any such
breach, or (B) the Seller shall have demonstrated to the reasonable satisfaction
of the Program Agent (to be evidenced by written confirmation from the Program
Agent), within thirty (30) days after the Seller has knowledge of any such
breach, that the systems, procedures and/or reporting practices of the Affected
Sub-transfer Agent have been modified so as to avoid further breaches relating
to the information to be prepared by such Affected Sub-transfer Agent.

                                THE PROGRAM AGENT

                  Section 7.01. Authorization and Action.

                  The Purchaser hereby irrevocably appoints and authorizes the
Program Agent to take such action as agent on its behalf and to exercise such
powers under this Agreement, and the other Facility Documents as are delegated
to the Program Agent by the terms hereof and thereof, together with such powers
as are reasonably incidental thereto. As to any matters not expressly provided
for by this Agreement or the other Facility Documents, the Program Agent shall
not be required to exercise any discretion or take any action, but shall be
required to act or to refrain from acting (and shall be fully protected in so
acting or refraining from acting) upon the instructions of the Purchaser;
provided, however, that the Program Agent shall not be required to take any
action which exposes the Program Agent to personal liability or which is
contrary to this Agreement, the other Program Documents or Applicable Law.

                  Section 7.02. Program Agent's Reliance, Etc.

                  Neither the Program Agent nor any of its directors, officers,
agents or employees shall be liable for any action taken or omitted to be taken
by it or them under or in connection with this Agreement or any of the other
Program Documents, except for its or their own gross negligence or willful
misconduct. Without limiting the generality of the foregoing, the Program Agent:
(i) may consult with legal counsel (including counsel for the Seller, the
Distributor or the Advisor), independent public accountants and other experts
selected by it and shall not be liable for any action taken or omitted to be
taken in good faith by it in accordance with the advice of such counsel,
accountants or experts; (ii) makes no warranty or representation to the
Purchaser and shall not be responsible to the Purchaser for any statements,
warranties or representations (whether written or oral) made in or in connection
with this Agreement or the other Program Documents; (iii) shall not have any
duty to ascertain or to inquire as to the performance or observance of any of
the terms, covenants or conditions of this Agreement or the other Program
Documents on the part of the Seller (as Servicer or otherwise), the Distributor
or the Advisor or to inspect the property (including the books and records) of
the Seller, the Distributor or the Advisor; (iv) shall not be responsible to the
Purchaser for the due execution, legality, validity, enforceability,
genuineness, sufficiency or value of this Agreement, the other Program Documents
or any other instrument or document furnished pursuant hereto or thereto; and
(v) shall incur no liability under or in respect of this Agreement or any other
Program Document by acting upon any notice, consent, certificate or other
instrument or writing (which may be by telecopier, telegram, cable or telex)
believed by it to be genuine and signed or sent by the proper party or parties.

                  Section 7.03. Indemnification.

                  The Purchaser agrees to indemnify the Program Agent (to the
extent not reimbursed by or on behalf of the Seller) from and against any and
all liabilities, obligations, losses, damages, penalties, actions, judgments,
suits, costs, expenses or disbursements of any kind or nature whatsoever which
may be imposed on, incurred by, or asserted against the Program Agent in any way
relating to or arising out of this Agreement or any other Program

                                       25
<PAGE>   30

Document or any action taken or omitted by the Program Agent under this
Agreement or any other Program Document; provided, that the Purchaser shall not
be liable for any portion of such liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements resulting
from the gross negligence or willful misconduct of the Program Agent. Without
limitation of the foregoing, the Purchaser agrees to reimburse the Program Agent
promptly upon demand for any out-of-pocket expenses (including counsel fees)
incurred by the Program Agent in connection with the preparation, execution,
delivery, administration, modification, amendment or enforcement (whether
through negotiations, legal proceedings or otherwise) or legal advice in respect
of rights or responsibilities under this Agreement or the other Program
Documents, to the extent that the Program Agent is not reimbursed for such
expenses by or on behalf of the Seller.

                  Section 7.04. Rights of the Program Agent.

                  The Seller hereby agrees that the Program Agent is hereby
authorized to deliver an Allocation Notice to the Collection Agent (i) upon the
occurrence of any Event of Termination (or event which with the passage of time
or notice, or both, would constitute an Event of Termination) which relates to
the Seller, the Distributor, the Advisor or any Significant Affiliate, or (ii)
at any time that the Program Agent in its sole discretion believes that the
event contemplated in Section 6.01(f) could occur in respect of the Seller, the
Distributor, the Advisor or any of their Significant Affiliates.

                                  ARTICLE VIII

                  Section 8.01. Undertakings; Payment of Damages.

                  The Seller hereby irrevocably and unconditionally agrees for
the benefit of (i) the Purchaser and the Program Agent, and (ii) in respect of
the obligations of the Distributor, the Transfer Agent and the Advisor under the
Facility Documents to cause the Distributor and the Transfer Agent to perform
and punctually and completely carry out each and every covenant of the
Distributor, the Advisor and the Transfer Agent under this Agreement, the
Transfer Agreement, the Servicing Agreement and each other Facility Document in
accordance with the terms thereof.

                  Section 8.02. Agreement Not Affected.

                  The Purchaser and the Program Agent may proceed to exercise
any right or remedy which it might have pursuant to this Article VIII without
regard to any actions or omissions of the Purchaser, the Program Agent or any
other Person. The validity of this Article VIII shall not be affected by any
action or inaction which may be taken under or in respect of any Program
Document. The Purchaser and the Program Agent at its option may proceed in the
first instance against the Seller to obtain a remedy under any Program Document
in the amount and in the manner set forth in such Program Document, without
being obliged to resort first to any claim or action against the Distributor,
the Advisor or the Transfer Agent.

                  Section 8.03. Waiver of Notice; No Offset; No Subrogation.

                  The Seller hereby waives any and all notices or demands to
which it may otherwise be entitled in connection with the pursuit of any remedy
hereunder, under any other Facility Document or, to the extent permitted under
Applicable Law; provided, that this sentence shall not constitute a waiver on
behalf of the Distributor, the Advisor or the Transfer Agent of any notice or
demand to which the Distributor, the Advisor or the Transfer Agent is entitled
under the Facility Documents. The obligations of the Seller under this Article
VIII shall not be subject to any defense, counterclaim or right of offset which
the Seller, the Distributor, the Advisor or any other Person has or may have
against the Purchaser, the Program Agent or any other Person, whether in respect
of this Agreement, any other Facility Document, any Purchased Receivables or
otherwise, but nothing herein shall limit the right of the Seller to pursue any
claim in a separate action.

                                   ARTICLE IX
                                  MISCELLANEOUS

                  Section 9.01. No Waiver; Modifications in Writing.

                  No failure or delay on the part of the Program Agent or the
Purchaser exercising any right, power or remedy hereunder shall operate as a
waiver thereof, nor shall any single or partial exercise of any such right,
power or remedy preclude any other or further exercise thereof or the exercise
of any other right, power or remedy. The remedies provided for herein are
cumulative and are not exclusive of any remedies that may be available to the
Program Agent and the Purchaser, at law or in equity. No amendment,
modification, supplement, termination or waiver of this Agreement shall be
effective unless the same shall be in writing and signed by each of the parties
hereto. Any waiver of any provision of this Agreement, and any consent to any
departure by any party to this Agreement from the terms of any provision of this
Agreement, shall be effective only in the specific instance and for the specific
purpose for which given. No notice to or demand on any party to this Agreement
in any case shall entitle the Seller, the Advisor or the Distributor to any
other or further notice or demand in similar or other circumstances.

                  Section 9.02. Payment.

                  Unless otherwise provided herein, whenever any payment to be
made hereunder shall be due on a non-Business Day, such payment shall be made on
the next succeeding Business Day. All amounts owing and payable by the Seller,
the Advisor or the Distributor to the Purchaser or the Program Agent under this
Agreement shall be paid in immediately available funds without counterclaim,
setoff, deduction, defense, abatement, suspension or deferment, but nothing
herein shall limit the right of the Seller, the Advisor or the Distributor to
pursue any claim in a separate action. Each of the Seller, the Advisor and the
Distributor hereby agrees to pay interest on any amounts payable by it under
this Agreement, which shall not be paid in full when due, for the period
commencing on the due date thereof until, but not including, the date the same
is paid in full at the Post-Default Rate. For purposes of calculating the
Post-Default Rate Interest, any amount received by or on behalf of the Purchaser
or the Program Agent after

                                       27
<PAGE>   32

3:00 p.m. (New York City time) shall be deemed to have been received on the next
succeeding Business Day.

contemplated hereby are actually consummated, the Seller agrees to promptly pay
on demand (i) all reasonable costs and expenses in connection with the
administration and any modification, amendment and waiver of this Agreement, the
Transfer Agreement, the Servicing Agreement and the other Facility Documents,
provided, however, that the Program Agent agrees to pay the reasonable costs
associated with any amendment or modification of the Facility Documents, if such

breach by, or by a change in circumstances relating to, the Seller, the

any of, the foregoing (each, an "Indemnified Party") from and against any and
all damages, losses, liabilities, expenses, obligations, penalties, actions,
suits, judgments and disbursements of any kind or nature whatsoever (including,
without limitation, the reasonable fees and disbursements of counsel)
(collectively the "Liabilities") that are incurred by or asserted or awarded
against any Indemnified Party, in each case arising out of or in connection with
or by reason of (and regardless of whether or not any such transactions are
consummated) any of the transactions contemplated by the Facility Documents,
including without limitation, any one or more of following:

                  (i) the execution, delivery, enforcement, performance,
         administration of, or otherwise arising out of or incurred in

         litigation or proceeding arising out of this Agreement or any other
         Facility Documents or the transactions contemplated hereby or thereby ;

         9.04(b)(ii) to indemnify any Indemnified Party in respect of any
         Liability described in this clause (ii) shall be limited, solely in
         respect of costs and expenses

         incurred in the preparation of any such defense during the period prior
         to the date that any service of process (whether as a party, as a
         witness or otherwise) is made on such Indemnified Party (or any other
         Person with custody over the Purchased Receivables, the Collections or
         Proceeds thereof) in respect thereof, to $100,000 in respect of such
         costs and expenses of such Indemnified Party relating to any single
         investigation, litigation or proceeding and to $200,000 in respect of
         all such costs and expenses of such Indemnified Party, incurred during
         any twelve month period, relating to all to such investigations,

         or otherwise) or the Advisor to perform any of its obligations,
         covenants, or agreement contained in any Facility Documents to which it
         is a party promptly and fully;

                  (iv) any representation or warranty made or deemed made by the
         Distributor, the Seller (as Servicer or otherwise) or the Advisor,

         certificate, written statement or report (including without limitation
         each Purchase Report, each Transfer Agent Report and each Sub-transfer
         Agent Report) delivered by or on behalf of any such Person in
         connection herewith or therewith is, or is alleged (by Persons other
         than the Indemnified Party) to have been false or misleading in any
         respect when made or any information (including without limitation any
         Sub-transfer Agent Report or any Transfer Agent Report) prepared or
         provided by the Seller, the Distributor, the Advisor, any of their
         Affiliates, any Sub-transfer Agent, Transfer Agent or by any other
         Person (including, without limitation, any Unaffiliated Agent) to the
         Purchaser or the Program Agent in writing for purposes of or in
         connection with any Facility Document shall fail to be true, correct
         and complete in all material respects on the date such information is
         stated or certified or any such information shall contain any material
         misrepresentation or any omission to state therein matters necessary to

         respect;

                  (v) any failure by the Distributor, the Seller (as Servicer or
         otherwise) or the Advisor to comply promptly and fully with any
         Applicable Law or any contractual obligation binding upon it;

                  (vi) any failure of any transfer of Receivables by the
         Distributor to the Seller under the Transfer Agreement or any failure
         of any transfer of Receivables by the Seller to the initial Purchaser
         under this Agreement to constitute a True Sale;

                  (vii) any failure to vest in the Purchaser a first priority
         perfected ownership interest in the Purchased Receivables, the
         Ancillary Rights with respect thereto and the Collections related
         thereto free and clear of all Adverse Claims;

                  (viii) any action or omission, not expressly required or
         contemplated to occur by the Facility Documents by the Distributor, the
         Seller (as Servicer or otherwise) or the Advisor, which has the effect
         of reducing or impairing the rights of the Purchaser or the Program
         Agent with respect to the Purchased Receivables and the Collections

                                       31
<PAGE>   36

         related thereto or under any Facility Document or which otherwise gives
         rise to an Adverse Effect;

                  (ix) any failure by the Distributor, the Seller (as Servicer
         or otherwise) or the Advisor, to make or cause to be made in the manner
         and when due any payment or deposit required to be paid by such party
         pursuant to any Facility Document;

                  (x) any failure of any Distribution Plan, any Irrevocable
         Payment Instruction, any Underwriting Agreement or any other Facility
         Document to comply with any Applicable Law, unless such failure results
         from the failure of the Program Agent to, at the written request of the
         Seller (which written request shall specify that such amendment is
         required for such document to comply with Applicable Law), consent to
         an amendment to any such document which could not give rise to a
         reasonable possibility of an Adverse Effect and which is necessary in
         order for such document to comply with the Applicable Law;

                  (xi) the execution, delivery, enforcement, performance,
         administration of, any Selling Agent's Agreement, the failure or
         alleged failure (by Persons other than the Indemnified Party) of any
         Selling Agent to perform its obligations under any Selling Agent's
         Agreement to which it is a party, any representation or warranty made
         by any Selling Agent is, or is alleged (by Persons other than the
         Indemnified Party) to have been false or misleading in any respect when
         made or deemed made, the failure of any Selling Agent to comply
         promptly and fully with Applicable Law, or any other action or omission
         by any Selling Agent not expressly required or contemplated to occur by
         the Program Documents;

                  (xii) the failure of any condition precedent set forth in
         Article III of this Agreement to be fully satisfied;

                  (xiii) any proceeding by or against the Distributor, the
         Seller (as Servicer or otherwise) or the Advisor seeking to adjudicate
         such Person, bankrupt or insolvent, or seeking liquidation, winding up,
         administration, reorganization, arrangement, adjustment, protection,
         relief, or composition of such Person or the debts of such Person under
         any Law relating to bankruptcy, insolvency, liquidation,
         administration, reorganization or relief of debtors or seeking the
         entry of an order for relief or the appointment of a receiver, trustee,
         custodian, administrator, liquidator, or other similar official for
         such Person or for a substantial part of such Person's property;

                  (xiv) any change in Applicable Law after May 2, 1995 which
         causes any of the representations and warranties of the Distributor or
         the Seller (as Servicer or otherwise) set forth herein or in any
         Facility Document to no longer be true and correct as though such
         representation or warranty had been made on the date of such change in
         Applicable Law or which alters the obligations of the Distributor, the
         Seller (as Servicer or otherwise), the Advisor or any Company as set
         forth in the Facility Documents other than in each case (i) a change in
         Law applicable on an industry wide basis resulting in a Complete
         Termination of the Distribution Plan of any Fund, or (ii) a reduction
         in the Maximum Aggregate Sales Charge Allowable or in the annual
         limitation on the amount

                                       32
<PAGE>   37

         payable by any Company in respect of the Sales Charge in respect of the
         Receivables relating to any Fund resulting solely from a change in Law
         applicable on an industry wide basis;

                  (xv) the adoption by any Company or any Fund of a Liquidation
         Plan;

                  (xvi) any amendment to the Prospectus in respect of a Fund in
         effect on the date hereof which changes the computation or timing of
         the CDSC or the rights of the Distributor in respect thereof;

                  (xvii) Free Redemptions in excess of the Annual Redemption
         Threshold, it being understood that the amount payable in respect of
         this clause from and after the first day upon which the Annual
         Redemption Threshold has been met, shall be an amount equal to the
         CDSCs that would have been payable upon the redemption of each Share
         relating to a Purchased Receivable had each such excess redemption not
         constituted a Free Redemption and shall be paid in arrears on each
         Monthly Settlement Date);

                  (xviii) any Adverse Claim in respect of the Receivables or the
         Collections; and

                  (xix) the Seller's Class A and C CDSC Portion being remitted
         to the Demand Deposit Account or the Collection Account, including
         without limitation, the Seller's failure to properly identify such
         amounts.

provided, however, that the Seller shall not be required to indemnify any
Indemnified Party in respect of any Liability to the extent such Liability: (I)
is found in a final, non-appealable judgment by a court of competent
jurisdiction to have resulted directly and primarily from one or more of the
following (A) such Indemnified Party's gross negligence or willful misconduct,
or (B) the Purchased Receivables proving to be uncollectible, except to the
extent that such uncollectibility is attributable to what would not have
occurred but for any one or more of the events described in clauses (i) through
(xix); (II) constitutes a liability arising out of a Take-out Transaction,
except to the extent such Liability is attributable to or would not have
occurred but for any one or more of the events described in clauses (i) through
(xix) above; or (III) constitutes consequential damages, it being understood
that the limitation set forth in clause (III) of this Section 9.04(b) is not
intended to preclude any Transferee from being the beneficiary of, or from
having the same rights to indemnification under this Section 9.04(b) that such
Transferee would have as Purchaser if it were the signatory to this Agreement
and the other Facility Documents to which the Purchaser is a party.

                  (c) Without prejudice to the survival of any other agreement
of the Seller hereunder, the agreement and obligations of the Seller contained
in this Section 9.04 shall survive the termination of this Agreement.

                  Section 9.05. Taxes.

                  (a) Any and all payments by the Distributor, the Seller, the
Advisor, the Transfer Agent or any Company under this Agreement, the Transfer
Agreement, the Purchase Agreement, any Irrevocable Payment Instruction or any
other Facility Document shall be made

                                       33
<PAGE>   38

free and clear of and without deduction for any and all present or future taxes,
levies, imposts, deductions, charges or withholdings, and all liabilities with
respect thereto, excluding, taxes imposed on the recipient's income, and
franchise taxes imposed on the recipient, by (i) the United States federal
government, (ii) the jurisdiction under the laws of which the recipient is
organized or any political subdivision thereof, (iii) by the jurisdiction in
which is located the principal executive office of the recipient or any
political subdivision thereof or (iv) by any other jurisdiction which asserts
the authority to impose such tax on the basis of contacts the recipient
maintains with such jurisdiction other than the contacts arising out of the
transactions contemplated hereby (all such non-excluded taxes, levies, imposts,
deductions, charges, withholdings and liabilities being hereinafter referred to
as "Taxes"). If the Distributor, the Seller, the Advisor, the Transfer Agent or
any Company shall be required by Law to deduct any Taxes from or in respect of
any sum payable hereunder or under any other Facility Document, (i) the sum
payable hereunder or thereunder shall be increased as may be necessary so that
after making all required deductions (including deductions applicable to
additional sums payable under this Section 9.05) the recipient receives an
amount equal to the sum it would have received had no such deductions been made,
(ii) the Distributor, the Seller, the Advisor, the Transfer Agent or any Company
shall make such deductions and (iii) the Seller shall pay the full amount
deducted to the relevant taxation authority or other authority in accordance
with Applicable Law.

                  (b) In addition, the Seller agrees to pay any present or
future stamp or documentary taxes or any other excise or property taxes, charges
or similar levies which arise from any transfer of Receivables in connection
herewith or from the execution, delivery or registration of, or otherwise with
respect to, this Agreement, the Transfer Agreement or any other Facility
Document other than any such Tax imposed in respect of a Take-out Transaction
(hereinafter referred to as "Other Taxes").

                  (c) The Seller will indemnify the Program Agent and the
Purchaser for the full amount of Taxes or Other Taxes (including, without
limitation, any Taxes or Other Taxes imposed by any jurisdiction on amounts
payable under this Section 9.05) and any liability (including penalties,
interest and expenses) arising therefrom or with respect thereto, whether or not
such Taxes or Other Taxes were correctly or legally asserted, so long as there
is a reasonable basis for the assertion of such Taxes or Other Taxes. This
indemnification shall be made within 30 days from the date the Program Agent or
the Purchaser makes written demand therefor to the Seller.

                  (d) Within thirty (30) days after the date of any payment of
Taxes, the Seller will furnish to the Purchaser and the Program Agent the
original or a certified copy of a receipt evidencing payment thereof.

                  (e) Unless the Seller, the Distributor or the Advisor, as the
case may be, shall have assumed responsibility for contesting a Tax or Other Tax
described in paragraph (c) of this Section 9.05 as provided in the next
sentence, the Purchaser may, but shall have no obligation to contest, settle or
compromise such Tax or Other Tax. The Seller, the Distributor or the Advisor, as
the case may be, may pursue, at its sole cost and expense, such lawful rights as
are available at law to contest any Tax or Other Tax asserted against the
Purchaser or the Program Agent provided: (i) the Seller, the Distributor or the
Advisor, as the case may be, has assumed responsibility for such contest and the
Seller has conceded in writing its responsibility to

                                       34
<PAGE>   39

indemnify the Purchaser or the Program Agent, as the case may be, in accordance
with this Section, for the full amount of such Tax or Other Tax; (ii) such
contest is conducted in a manner which does not result in a Lien on the
Receivables and if the manner of contest does not defer the obligation to pay
the Tax or Other Tax, the Seller shall pay such Tax or Other Tax when due,
subject to the right to recover such Tax or Other Tax if the contest is
successful, (iii) to the extent not covered by Section 9.04(b), the Seller shall
have provided to the Purchaser or the Program Agent, as the case may be, such
undertakings as the Purchaser or the Program Agent, as the case may be, shall
request, in form and substance satisfactory to the Purchaser, or the Program
Agent, as the case may be, whereby the Seller agrees to hold the Purchaser or
the Program Agent, as the case may be, harmless from any and all liabilities,
costs and expenses which may arise as a consequence of such contest; (iv) the
Seller shall have furnished the Purchaser or the Program Agent, as the case may
be, with an opinion, in form and scope reasonably satisfactory to the Purchaser
or the Program Agent, as the case may be, of counsel reasonably satisfactory to
the Purchaser or the Program Agent, as the case may be, that there is a
meritorious basis for such contest; (v) the contest of such Tax or Other Tax may
be conducted in a manner which does not affect the liability of the Purchaser or
the Program Agent, as the case may be, for any tax not indemnified by Seller;
(vi) the contest of such Tax or Other Tax can be separated from any contest of
any other tax in respect of which the Seller has not indemnified Purchaser or
the Program Agent, as the case may be, without prejudicing the Purchaser's or
the Program Agent's, as the case may be, ability to deal with or otherwise
contest such other liability; and (vii) the Purchaser or the Program Agent, as
the case may be, has not waived its right to indemnification by the Seller in
respect of such Tax or Other Tax. The Seller shall keep the Purchaser or the
Program Agent, as the case may be, fully advised on a current basis concerning
any such contest, and, without limiting the foregoing: (a) the Seller shall give
the Purchaser or the Program Agent, as the case may be, reasonable notice of and
a reasonable opportunity to be present in person or by counsel at any proceeding
in connection therewith; (b) the Seller shall give the Purchaser or the Program
Agent, as the case may be, notice of any proposed filings or papers to be served
or filed by the Seller in connection with any such proceedings and a reasonable
opportunity to comment upon them; and (c) the Seller shall promptly supply the
Purchaser or the Program Agent, as the case may be, with copies of any filings
or papers served upon the Seller in connection with such proceedings; it being
understood that the Purchaser or the Program Agent, as the case may be, shall
bear its own costs incurred in connection with any participation by the
Purchaser or the Program Agent, as the case may be, or its counsel in the
contest as contemplated by this sentence.

                  (f) In the event the Seller shall pay a Tax or Other Tax
pursuant to this Section 9.05 and all or a portion of such Tax or Other Tax
previously paid by Seller is later refunded by the applicable Taxing Authority
the recipient of such refund shall pay to the Seller the portion of such refund
which relates to the amount previously paid by the Seller.

                  (g) Without prejudice to the survival of any other agreement
of the Seller hereunder, the agreements and obligations of the Seller contained
in this Section 9.05 shall survive the termination of this Agreement.

                  Section 9.06. Execution in Counterparts.

                  This Agreement may be executed in any number of counterparts
and by different parties hereto on separate counterparts, each of which
counterparts, when so executed and delivered, shall be deemed to be an original
and all of which counterparts, taken together, shall constitute but one and the
same Agreement.

                  Section 9.07. Binding Effect; Assignment.

                  This Agreement shall be binding upon, and inure to the benefit
of, the parties hereto and their respective successors and assigns. Except as a
result of a Permitted Change in Control relating to the Seller, the Advisor or
the Distributor, neither the Seller nor the Distributor shall assign its rights
or obligations hereunder or in connection herewith or any interest herein
(voluntarily, or by operation of law or otherwise) without the Program Agent's
and the Purchaser's prior written consent. This Agreement and the Program
Agent's and the Purchaser's rights herein (including without limitation in
respect of the Purchased Receivables, the Collections and the Ancillary Rights
with respect thereto) shall be assignable, in whole or in part, by the Purchaser
and the Program Agent and their respective successors and assigns; provided,
however, that in connection with any proposed Take-out Transaction, prior to
distributing to potential investors any offering materials which contain
information describing the Seller, the Advisor, the Distributor or any of their
respective Affiliates, the Program Agent shall give the Seller a reasonable
opportunity to review and comment upon such portion of such materials. Unless
the Purchaser reasonably determines that disclosure is required in order to
comply with Law applicable to such Take-out Transaction, the Purchaser shall not
make any disclosure which the Seller reasonably identifies in its comments
pursuant to the preceding sentence as material, non-public information
concerning the Seller or any of its Affiliates, the release of which would have
a material adverse consequence to the Seller or any of its Affiliates (the
"Prohibited Financial Information"); provided, however, that in connection with
the initial offering of any securities in a Take-out Transaction involving any
Purchased Receivables, the Purchaser shall not make any disclosure which the
Seller reasonably identifies as Prohibited Financial Information. Subject to
Section 9.15, each of the Seller, the Advisor and the Distributor hereby
consents to the Purchaser and the Program Agent entering into the Take-out
Transactions.

                  Section 9.08. Governing Law; Submission to Jurisdiction.

                  (a) THIS AGREEMENT SHALL BE DEEMED TO BE A CONTRACT MADE UNDER
THE LAWS OF THE STATE OF NEW YORK AND FOR ALL PURPOSES SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAWS OF SAID STATE WITHOUT REGARD TO ITS
CONFLICTS OF LAWS PROVISIONS.

                  (b) Each of the Seller, the Advisor and the Distributor hereby
irrevocably submits itself to the non-exclusive jurisdiction of the courts of
the State of New York and to the non-exclusive jurisdiction of any Federal Court
of the United States located in the southern district of New York, for the
purposes of any suit, action or other proceeding arising out of this Agreement,
the Servicing Agreement, the Collection Agency Agreement or any of the
transactions contemplated hereby or thereby.

                  Section 9.09. Severability of Provisions.

                  Any provision of this Agreement which is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability without invalidating the
remaining provisions hereof or affecting the validity or enforceability of such
provision in any other jurisdiction.

                  Section 9.10. Confidentiality.

                  Unless otherwise required by Applicable Law, each of the
Seller, the Advisor and the Distributor agrees to use commercially reasonable
efforts to maintain the confidentiality of the Facility Documents (and all
drafts hereof and thereof) and the transactions contemplated thereby other than
the Transfer Agent's Agreement, the Underwriting Agreements, the Advisory
Agreements, the Distribution Plan and the Prospectuses in communications with
third parties and otherwise; provided, that such documents and the transactions
contemplated thereby may be disclosed (i) to third parties to the extent such
disclosure is consented to in writing by the Program Agent (which consent shall
not be unreasonably withheld) and such disclosure is made pursuant to a written
confidentiality agreement in form and substance substantially identical to this
Section 9.10, and (ii) the officers, partners, directors and employees, legal
counsel and auditors of the Seller, the Advisor and the Distributor.

                  Section 9.11. Intent of Agreement.

                  It is the intention of this Agreement that each purchase of
Receivables hereunder and the Ancillary Rights with respect thereto shall convey
to the Purchaser an undivided 100% ownership interest in such Purchased
Receivables, the Collections in respect thereto and the Ancillary Rights with
respect thereto on the Purchase Date therefor and that such transactions shall
constitute a True Sale and not a secured loan. If, notwithstanding such
intention, any conveyance of Receivables and the Collections and the Ancillary
Rights with respect thereto from the Seller to the Purchaser shall ever be
recharacterized as a secured loan and not a sale, it is the intention of this
Agreement that this Agreement shall constitute a security agreement under
Applicable Law, and that the Seller shall be deemed to have granted to the
Purchaser a duly perfected first priority security interest in all of the
Seller's right, title and interest in, to and under such Purchased Receivables,
the Collections and the Ancillary Rights in respect thereto free and clear of
any Adverse Claim.

                  Section 9.12. Liability to any Company.

                  No obligation or liability to any Company, the Seller, the
Advisor, the Distributor, any shareholder of any Fund or any Person contracting
with or related to any Company is intended to be assumed by the Program Agent or
the Purchaser under or as a result of this Agreement or the other Program
Documents and the transactions contemplated hereby and thereby and, to the
maximum extent permitted under provisions of Law, the Program Agent and the
Purchaser expressly disclaim any such assumption. The Seller shall indemnify,
defend and hold harmless the Program Agent and the Purchaser from any loss,
liability or expense incurred as a result of any claim that any such obligation
or liability has been so assumed.

                  Section 9.13. Merger.

                  The Facility Documents taken as a whole incorporate the entire
agreement between the parties thereto concerning the subject matter thereof. The
Facility Documents supersede any prior agreements among the parties relating to
the subject matter thereof.

                  Section 9.14. Further Acts.

                  Each party agrees that at any time, and from time to time, it
will do all such things and execute and deliver all such instruments,
assignments, other documents and assurances, as such other party or its counsel
reasonably deems necessary or desirable in order to carry out the express
intent, purpose and conditions of this Agreement and the other Facility
Documents and the transactions contemplated hereby and thereby, and without
limiting the generality of the foregoing, to the extent permitted by Applicable
Law, upon the Program Agent's or the Purchaser's written request from time to
time, each of the Seller, the Advisor and the Distributor shall make, execute,
acknowledge and deliver and file and record in the proper filing and recording
places all such instruments, and take all such actions, as the Program Agent or
the Purchaser may reasonably deem necessary or advisable for assuring or
confirming to the Purchaser its rights and interest in and to, and remedies in
respect of, the Purchased Receivables, the Ancillary Rights and the Collections
related thereto.

                  Section 9.15. Assignee Rights; Etc.

                  (a) Each of the Seller, the Advisor and the Distributor
acknowledges and agrees that any Person which purchases or otherwise acquires
any interest in any Purchased Receivables or the Ancillary Rights in respect
thereof (or the right to receive any Collections with respect thereto) in a
Take-out Transaction (each such Person, a "Transferee"), (and in the case of
indemnities, their respective Affiliates and their officers, directors,
employees and agents) shall each, to the extent of such Transferee's interest,
be a beneficiary of the representations, warranties, indemnities, covenants,
agreements and undertakings of the Seller, the Advisor and the Distributor under
this Agreement and the other Facility Documents to which it is a party;
provided, that such rights of the Transferees in a Take-out Transaction may be
enforced on behalf of such Transferees only by the Master Servicer for the
related Master Trust. Each of the Seller, the Advisor and the Distributor agree
to execute and deliver such instruments and documents and shall take all such
actions as the Program Agent, the Purchaser or any Master Trust shall reasonably
deem necessary in order to permit the Purchaser to convey any portion of its
right, title and interest in, to or under the Purchased Receivables or the
Ancillary Rights and Collections in respect thereof to any Transferee and to
confer upon any such Transferee the rights and privileges in and to the
Purchased Receivables and the Ancillary Rights in respect thereof to which such
Transferee has an interest and under the Facility Documents to the extent of
such transfer and assignment. Notwithstanding anything in this Section 9.15 to
the contrary, no Transferee shall be deemed to have assumed any of the
obligations or liabilities of the Seller or the Distributor under this Agreement
or any other Program Document. No such transfer to a Transferee shall alter the
obligations of the Seller, the Advisor or the Distributor hereunder.

                  (b) Subject to the other requirements set forth in Section
9.07, the Program Agent agrees that any written offering memorandum or circular
used in connection with any

                                       38
<PAGE>   43

Take-out Transaction involving Purchased Receivables which contains information
concerning the Seller or the Distributor shall (i) incorporate language
substantially in the form of Schedule VI hereto, and (ii) provide that the
securities which are the subject of such Take-out Transaction will be offered
only to institutional accredited investors (as defined in Rule 501(a) under the
Securities Act), to a qualified institutional buyer within the meaning of Rule
144A under the Securities Act and/or to any Person in a transaction exempt from
registration under the Securities Act. The Program Agent also agrees that each
Take-out Transaction involving Purchased Receivables shall be structured in a
manner so that the securities which are the subject of such Take-out Transaction
are to be offered and sold in a transaction exempt from registration under the
Securities Act.

                  Each of the Seller, the Advisor and the Distributor
acknowledges that under the documentation to be entered into in connection with
Take-out Transactions involving the Purchased Receivables (the "Take-out
Documents") the holders of the securities issued in connection with such
Take-out Transaction may have the right to consent to the Purchaser and the
Program Agent taking certain actions and consenting to certain amendments,
modifications or waivers under the Program Documents (collectively, the
"Actions"). The Program Agent agrees that without the prior written consent of
the Seller (which consent shall not be unreasonably withheld or delayed) the
Take-out Documents relating to any Take-out Transaction shall not provide that
more than the holders which in the aggregate have a 51% interest in the
securities of each class issued in connection with such Take-out Transaction
(the "Holders") be required to consent to the Purchaser or the Program Agent
taking any Action; provided, however, that with respect to any Action which
could affect the amount or timing of Collections relating to Purchased
Receivables or which amend or modify the Allocation Procedures, the Take-out
Documents may provide that the consent of the holders which in the aggregate
have a 66-2/3% interest in the securities of any class issued in connection with
such Take-out Transaction be required for the Purchaser or the Program Agent to
take any such Action; provided, further, that no Holders (other than Citibank
and Citicorp North America, Inc.) will be entitled to require that the Program
Agent declare the Termination Date to have occurred following any Event of
Termination.

                  Section 9.16. Specific Performance; Other Rights and Remedies.

                  The parties hereto recognize that certain of their rights
under this Agreement and the other Facility Documents are unique and,
accordingly, the parties hereto shall, in addition to such other remedies as may
be available to any of them at law or in equity or under this Agreement and the
other Facility Documents, have the right to enforce their rights hereunder and
thereunder by actions for injunctive permitted relief and specific performance
to the extent permitted by Applicable Law. The rights and remedies of the
Program Agent and the Purchaser under this Agreement and the other Facility
Documents are cumulative and are not in lieu of, but are in addition to, any
other rights and remedies which the Program Agent and the Purchaser may have
under or by virtue of any Applicable Law, or in equity, or any other agreement
or obligations to which the Program Agent and the Purchaser is a party. The
rights and remedies of the Program Agent and the Purchaser under this Agreement
and the other Facility Documents may be exercised from time to time and as often
as such exercise is deemed expedient. Without limiting the generality of the
foregoing, each of the Seller, the Advisor and the Distributor acknowledges and
agrees that it will be impossible to measure in money the damage to the

                                       39
<PAGE>   44

Program Agent or the Purchaser in the event of a breach of any of the terms and
provisions of this Agreement or any other Program Document, and that, in the
event of any such breach, the Program Agent and the Purchaser may not have an
adequate remedy at Law, although the foregoing shall not constitute a waiver of
any of the Program Agent's or the Purchaser's rights, powers, privileges and
remedies against or in respect of a breaching party, any collateral or any other
Person or thing under this Agreement, any other Facility Document or Applicable
Law. It is therefore agreed that each of the Program Agent and the Purchaser, in
addition to all other such rights, powers, privileges and remedies that it may
have, shall be entitled to injunctive relief, specific performance or such other
equitable relief as it may request to exercise or otherwise enforce any of the
terms of those provisions and to enjoin or otherwise restrain any act prohibited
thereby, and each of the Seller, the Advisor and the Distributor agree that it
shall not argue and hereby waives any defense that there is an adequate remedy
available at Law.

Agreement to be executed by their respective officers thereunto duly authorized,
