                             DISTRIBUTION AGREEMENT


                  Amendment No. 1 , made this 1st day of March 1999 by and
between AIM SUMMIT FUND, INC., a Maryland corporation (the "Company") and A I M
DISTRIBUTORS, INC., a Delaware corporation (the "Distributor") to that certain
agreement made as of the 28th day of February, 1997 (the "Distribution
Agreement").

                  WHEREAS, the Company and the Distributor have entered into the
Distribution Agreement; and

                  WHEREAS, the Company has divided its common stock into two
classes named Class I Shares and Class II Shares; and

                  WHEREAS, the parties desire to clarify that the Distributor
will act as the principal distributor of both Class I Shares and Class II Shares
of Common Stock; and

                  WHEREAS, the Distributor is to be compensated by the Company
for distribution efforts relating to Class II Shares.

                  NOW, THEREFORE, in consideration of the premises and of other
good and valuable consideration by each of the parties hereto to the other party
paid and of the agreements, covenants and obligations herein contained and
intending to be legally bound, the parties hereto agree as follows:

1.                Except as set forth below, the terms "Company shares," "its
                  shares," "Company common stock" and "its common stock" as used
                  in the Distribution Agreement shall mean Class I Shares and
                  Class II Shares of the Company.

2.                Section 1(b) provides that the Distribution Agreement may be
                  continued by the affirmative vote of a specified percentage of
                  the holders of the Company's shares. Section 11 provides that
                  the Distribution Agreement may be terminated by the vote of a
                  majority of the outstanding voting securities of the Company.
                  In order to make it clear that the Distribution Agreement may
                  be continued or terminated, as the case may be, on a class
                  basis, all references to the Company's shares or to the
                  outstanding voting securities of the Company in paragraph 1(b)
                  and paragraph 11 of the Distribution Agreement shall mean
                  Class I Shares or Class II Shares of the Company, as the case
                  may be.

3.                A new paragraph 12 shall be added which reads in its entirety
                  as follows:

                  12.      Subject to the limitations, if any, of applicable law
                           including the applicable National Association of
                           Securities Dealers, Inc. ("NASD") Conduct Rules
                           (formerly, the NASD Rules of Fair Practice) regarding
                           asset-based sales charges, the Company shall pay to
                           the Distributor as a reimbursement for all or a
                           portion of such expenses, or as


   2


                           reasonable compensation for distribution of the Class
                           II Shares, an asset-based sales charge in an amount
                           equal to 0.05% per annum of the average daily net
                           asset value of the Class II Shares from time to time
                           (the "Distributor's 12b-1 Share"), such sales charge
                           to be payable pursuant to the distribution plan
                           adopted pursuant to Rule 12b-1 under the Investment
                           Company Act of 1940 Act (the "Plan"). The
                           Distributor's 12b-1 Share shall accrue daily and be
                           paid to the Distributor as soon as practicable after
                           the end of each such calendar month (unless the
                           Distributor shall specify a later date in written
                           instructions to the Company). The Distributor shall
                           maintain adequate books and records to permit
                           calculations periodically (but not less than monthly)
                           of, and shall calculate on a monthly basis, the
                           Distributor's 12b-1 Share to be paid to the
                           Distributor. The Company shall be entitled to rely on
                           Distributor's books, records and calculations
                           relating to Distributor's 12b-1 Share.

4.                Except as modified by this Amendment Agreement, the
                  Distribution Agreement is hereby ratified and confirmed and
