  THIS ANNOUNCEMENT IS NOT AN OFFER TO PURCHASE OR A SOLICITATION OF AN OFFER
        TO SELL SHARES. THE OFFER IS MADE ONLY BY THE OFFER TO PURCHASE
         DATED AUGUST 12, 1999, AND THE RELATED LETTER OF TRANSMITTAL.

                      NOTICE OF OFFER TO PURCHASE FOR CASH
               3,800,000 OF THE ISSUED AND OUTSTANDING SHARES OF
                             AIM FLOATING RATE FUND
                          AT NET ASSET VALUE PER SHARE

AIM Floating Rate Fund (the "Fund") is offering to purchase 3,800,000 of its
issued and outstanding shares ("Shares") at a price equal to its net asset value
("NAV"), less any applicable early withdrawal charge, as of the close of the New
York Stock Exchange on the Expiration Date, September 10, 1999. The Offer will
expire at 5:00 p.m., New York City time on that date, unless extended, upon the
terms and conditions set forth in the Offer to Purchase dated August 12, 1999
and the related Letter of Transmittal, which together constitute the "Offer."
The Fund's NAV was $9.79 per Share as of August 6, 1999. The applicable early
withdrawal charge will be deducted from the proceeds of Shares tendered. The
purpose of the Offer is to provide liquidity to shareholders since the Fund is
unaware of any secondary market which exists for the Shares. The Offer is not
conditioned upon the tender of any minimum number of Shares.

If more than the number of Shares contemplated by this Offer are duly tendered
prior to the expiration of the Offer, assuming no changes in the factors
originally considered when the decision to make the Offer was made, the Fund
will either (1) extend the Offer period, if necessary, and increase the number
of Shares that the Fund is offering to purchase to an amount which it believes
will be sufficient to accommodate the excess Shares tendered as well as any
additional Shares that may be tendered during the extended Offer period or (2)
purchase the number of Shares sought on a pro rata basis.

Shares tendered pursuant to the Offer may be withdrawn at any time prior to
5:00 p.m., New York City time, on September 10, 1999, and, if not yet accepted
for payment by the Fund, Shares may also be withdrawn after October 8, 1999.

The information required to be disclosed by paragraph (d)(1) of Rule 13e-4 under
the Securities Exchange Act of 1934, as amended, is contained in the Offer to
Purchase and is incorporated herein by reference.

The Offer to Purchase and the related Letter of Transmittal contain important
information that should be read carefully before any decision is made with
respect to the Offer.

Requests for free copies of the Offer to Purchase, Letter of Transmittal and any
other tender offer documents may be directed to the address and telephone number
below. Shareholders who do not own Shares directly should effect a tender
through their broker, dealer or nominee.

         OFFER TO PURCHASE FOR CASH AT NET ASSET VALUE UP TO 3,800,000
                  OF ITS ISSUED AND OUTSTANDING COMMON SHARES

         THE EXPIRATION DATE AND THE WITHDRAWAL DEADLINE IS 5:00 P.M.,
          NEW YORK CITY TIME, ON SEPTEMBER 10, 1999, UNLESS EXTENDED.

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

To the Holders of Shares of AIM FLOATING RATE FUND:

     Commencing August 12, 1999, the Fund is offering to purchase up to
3,800,000 of its shares of common stock, par value $.001 per share (the
"Shares"), for cash at a price equal to their net asset value ("NAV"), less any
applicable Early Withdrawal Charge, as of the close of regular trading on the
New York Stock Exchange on September 10, 1999 (the "Initial Expiration Date"),
unless extended, upon the terms and conditions set forth in this Offer to
Purchase (the "Offer") and the related Letter of Transmittal.

     The Shares are not traded on an established secondary market and, to
provide liquidity to Fund shareholders, the Fund's board of directors (the
"Board") presently intends each quarter to consider making a tender offer for
all or a portion of its Shares at a price per Share equal to its then current
NAV, less any applicable early withdrawal charge. The NAV on August 6, 1999 was
$9.79 per Share. You may obtain current NAV quotations during the pendency of
the Offer by calling (800) 959-4246.

     If more than the number of Shares contemplated by this Offer are duly
tendered prior to the expiration of the Offer, assuming no changes in the
factors originally considered by the Board when it determined to make the Offer,
the Fund will either (1) extend the Offer period, if necessary, and increase the
number of Shares that the Fund is offering to purchase to an amount which it
believes will be sufficient to accommodate the excess Shares tendered as well as
any additional Shares that may be tendered during the extended Offer period or
(2) purchase the number of Shares sought on a pro rata basis.

     THIS OFFER IS BEING MADE TO ALL SHAREHOLDERS OF THE FUND AND IS NOT
CONDITIONED UPON ANY MINIMUM NUMBER OF SHARES BEING TENDERED.

     IMPORTANT: If you desire to tender all or any portion of your Shares, you
should do one of the following: (1) if you own your Shares through a broker,
dealer, commercial bank, trust company or other nominee (each a "Nominee"),
request your Nominee to effect the transaction for you or (2) if you own your
Shares directly, complete and sign the Letter of Transmittal and mail or deliver
it along with any Share certificate(s) and any other required documents to the
Fund's transfer agent, A I M Fund Services, Inc. (the "Transfer Agent"). If your
Shares are registered in the name of a Nominee, you must contact such Nominee if
you desire to tender your Shares.

     NEITHER THE FUND NOR ITS BOARD OF DIRECTORS MAKES ANY RECOMMENDATION TO ANY
SHAREHOLDER AS TO WHETHER TO TENDER OR REFRAIN FROM TENDERING SHARES. EACH
SHAREHOLDER MUST MAKE HIS OWN DECISION WHETHER TO TENDER SHARES, AND IF SO, HOW
MANY SHARES TO TENDER.

     NO PERSON HAS BEEN AUTHORIZED TO MAKE ANY RECOMMENDATION ON BEHALF OF THE
FUND AS TO WHETHER SHAREHOLDERS SHOULD TENDER SHARES PURSUANT TO THE OFFER. NO
PERSON HAS BEEN AUTHORIZED TO GIVE ANY INFORMATION OR TO MAKE ANY
REPRESENTATIONS IN CONNECTION WITH THE OFFER OTHER THAN THOSE CONTAINED HEREIN
OR IN THE LETTER OF TRANSMITTAL. IF GIVEN OR MADE, SUCH
<PAGE>   2

RECOMMENDATION AND SUCH INFORMATION AND REPRESENTATIONS MUST NOT BE RELIED UPON
AS HAVING BEEN AUTHORIZED BY THE FUND.

this Offer to Purchase and the Letter of Transmittal may be directed to the

distribution expenses will be assessed on Shares accepted for purchase which
have been held for less than the applicable holding period (see Section 3).

     The Offer is being made to all shareholders of the Fund and is not
conditioned upon any number of Shares being tendered. If more than the number of
Shares sought by the Fund are duly tendered prior to the expiration of the
Offer, assuming no changes in the factors originally considered by the Board
when it determined to make the Offer, the Fund will either (1) extend the Offer
period, if necessary, and increase the number of Shares that the Fund is
offering to purchase to an amount which it believes will be sufficient to
accommodate the excess Shares tendered as well as any additional Shares that may
be tendered during the extended Offer period or (2) purchase the number of
Shares sought on a pro rata basis.

     The Fund reserves the right, in its sole discretion, at any time or from
time to time, to extend the period of time during which the Offer is open by
giving oral or written notice of such extension to the Transfer Agent and making
a public announcement thereof (see Section 15). There is no assurance, however,
that the Fund will exercise its right to extend the Offer. If the Fund decides,
in its sole discretion, to increase (except for any increase not in excess of 2%
of the outstanding Shares) or decrease the number of Shares being sought and, at
the time that notice of such increase or decrease is first published, sent or
given to holders of Shares in the manner specified below, the Offer is scheduled
to expire at any time earlier than the tenth business day from the date that
such notice is first so published, sent or given, the Offer will be extended at
least until the end of such ten business day period.

     As of August 6, 1999 there were approximately 37,946,064 Shares issued and
outstanding and there were 10,387 record holders of Shares. The Fund has been
informed that no other director, officer or affiliate of the Fund intends to
tender any Shares pursuant to the Offer. The Shares currently are not traded on
any established secondary market. Current NAV quotations for the Shares can be
obtained by calling the Transfer Agent at (800) 959-4246.

     2. PROCEDURE FOR TENDERING SHARES. In order for you to tender any of your
Shares pursuant to the Offer, you may either: (a) request your Nominee to effect
the transaction for you, in which case a Letter of Transmittal is not required
or (b) if the Shares are registered in your name, send to the Transfer Agent, at
the address set forth below, any certificates for such Shares, a properly
completed and executed Letter of Transmittal and any other documents required
therein. Please contact the Transfer Agent at (800) 959-4246 as to any
additional documents which may be required.

     A. Procedures for Beneficial Owners Holding Shares through Brokers,
Dealers, or other Nominees. If your Shares are registered in the name of a
Nominee, you must contact such Nominee if you desire to tender your Shares. You
should contact such Nominee in sufficient time to permit notification of your
desire to tender to reach the Transfer Agent by the Expiration Date. No
brokerage commission will be charged on the purchase of Shares by the Fund
pursuant to the Offer. However, a broker or dealer may charge a fee for
processing the transaction on your behalf.

     B. Procedures for Registered Shareholders. If you will be mailing or
delivering the Letter of Transmittal and any other required documents to the
Transfer Agent to tender your Shares, they must be received on or prior to the
Expiration Date by the Transfer Agent at its address set forth below.

     Signatures on the Letter of Transmittal are not required to be guaranteed
unless (1) the proceeds for the tendered Shares will amount to more than
$50,000, (2) the Letter of Transmittal is signed by someone other than the
registered holder of the Shares tendered therewith, or (3) payment for tendered
Shares is to be sent

                                        4
<PAGE>   5

to a payee other than the registered owner of such Shares or to an address other
than the registered address of the registered owner of the Shares. In each of
those instances, all signatures on the Letter of Transmittal must be guaranteed
by an "eligible guarantor institution," as such term is defined in Rule 17Ad-15
under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), the
existence and validity of which may be verified by the Transfer Agent through
the use of industry publications; notarized signatures are not sufficient.

     Please note that those shareholders holding Shares in an Individual
Retirement Account ("IRA") that mail or deliver a Letter of Transmittal to
tender Shares must also provide the Transfer Agent with a completed IRA
distribution form.

     Payment for Shares tendered and purchased will be made only after receipt
by the Transfer Agent on or before the Expiration Date of a properly completed
and duly executed Letter of Transmittal and any other required documents. If
your Shares are evidenced by certificates, those certificates must also be
received by the Transfer Agent on or prior to the Expiration Date.

     THE METHOD OF DELIVERY OF ANY DOCUMENTS, INCLUDING CERTIFICATES FOR SHARES,
IS AT THE ELECTION AND RISK OF THE PARTY TENDERING THE SHARES. IF DOCUMENTS ARE
SENT BY MAIL, IT IS RECOMMENDED THAT THEY BE SENT BY REGISTERED MAIL, PROPERLY
INSURED, WITH RETURN RECEIPT REQUESTED.

     C. Determinations of Validity. All questions as to the validity, form,
eligibility (including time of receipt) and acceptance of tenders will be
determined by the Fund, in its sole discretion, which determination shall be
final and binding. The Fund reserves the absolute right to reject any or all
tenders determined by it not to be in appropriate form or the acceptance of or
payment for which would, in the opinion of counsel for the Fund, be unlawful.
The Fund also reserves the absolute right to waive any of the conditions of the
Offer or any defect in any tender with respect to any particular Shares or any
particular shareholder, and the Fund's interpretations of the terms and
conditions of the Offer will be final and binding. Unless waived, any defects or
irregularities in connection with tenders must be cured within such times as the
Fund shall determine. Tendered Shares will not be accepted for payment unless
the defects or irregularities have been cured within such time or waived.
Neither the Fund, the Transfer Agent nor any other person shall be obligated to
give notice of any defects or irregularities in tenders, nor shall any of them
incur any liability for failure to give such notice.

     D. Tender Constitutes an Agreement. A tender of Shares made pursuant to any
one of the procedures set forth above will constitute an agreement between the
tendering shareholder and the Fund in accordance with the terms and subject to
the conditions of the Offer.

     3. EARLY WITHDRAWAL CHARGE. The Fund will assess an Early Withdrawal Charge
on Shares accepted for purchase which have been held for less than four years.
The charge will be paid to AIM Distributors to recover its distribution
expenses. The Early Withdrawal Charge will be imposed on those Shares accepted
for tender based on an amount equal to the lesser of the then current NAV of the
Shares or the shareholder's cost of the Shares being tendered. Accordingly, the
Early Withdrawal Charge will not be imposed on increases in the NAV above the
initial purchase price. In addition, the Early Withdrawal Charge will not be
imposed on Shares derived from reinvestments of dividends or capital gain
distributions. The Early Withdrawal Charge imposed will vary depending on the
length of time the Shares have been owned since purchase (separate purchases
shall not be aggregated for these purposes), as set forth in the following
table:

<TABLE>

                                                               EARLY WITHDRAWAL CHARGE
YEAR OF TENDER AFTER PURCHASE                                  (AS A PERCENTAGE OF NAV)

<S>                                                            <C>
First.......................................................             3.0%

Fourth......................................................             1.0%
Fifth and following.........................................             0.0%
</TABLE>

                                        5
<PAGE>   6

     In determining whether an Early Withdrawal Charge is applicable to a tender
of Shares, the calculation will be determined in the manner that results in the
lowest possible amount being charged. Therefore, it will be assumed that the
tender is first of Shares acquired through dividend reinvestment and of Shares
held for over four years and then of Shares held longest during the four-year
period. The Early Withdrawal Charge will not be applied to dollar amounts
representing an increase in the NAV since the time of purchase.

     4. EXCHANGES. Tendering shareholders may, instead of receiving the proceeds
from the tender of Shares of the Fund in cash, elect to have those proceeds
invested in Class B shares that are subject to a contingent deferred sales
charge ("Class B shares") of certain open-end investment companies ("AIM Funds")
managed or advised by A I M Advisors, Inc. ("AIM Advisors") purchased at their
respective NAVs determined on the Expiration Date. The Early Withdrawal Charge
will be waived for Shares tendered in exchange for Class B shares in the AIM
Funds; however, such Class B shares will immediately become subject to a
contingent deferred sales charge equivalent to the Early Withdrawal Charge on
Shares of the Fund. Thus, such Class B shares may be subject to a contingent
deferred sales charge upon a subsequent redemption from the AIM Funds. The
purchase of such Class B shares will be deemed to have occurred at the time of
the Fund's purchase of the Shares pursuant to the Offer for purposes of
calculating the applicable contingent deferred sales charge.

     The prospectus for each AIM Fund describes its investment objectives and
policies. Shareholders can obtain a prospectus without charge by calling (800)
347-4246 and should consider these objectives and policies carefully before
requesting an exchange. Each tender for an exchange must involve proceeds from
Shares that have a NAV of at least $500.

     5. WITHDRAWAL RIGHTS. You may withdraw Shares tendered at any time prior to
the Expiration Date and, if the Shares have not yet been accepted for payment by
the Fund, at any time after October 8, 1999.

     To be effective, any notice of withdrawal must be timely received by the
Transfer Agent at the address set forth below. Any notice of withdrawal must
specify the name of the person having deposited the Shares to be withdrawn, the
number of Shares to be withdrawn, and, if the certificates representing such
Shares have been delivered or otherwise identified to the Transfer Agent, the
name of the registered holder(s) of such Shares as set forth in such
certificates and the number of Shares to be withdrawn. If the certificates have
been delivered to the Transfer Agent, then, prior to the release of such
certificate, you must also submit the certificate numbers shown on the
particular certificates evidencing such Shares and the signature on the notice
of the withdrawal must be guaranteed by an eligible guarantor institution.
Shareholders whose accounts are maintained through a Nominee should notify such
nominee prior to the Expiration Date if they wish to withdraw Shares.

     All questions as to the form and validity (including time of receipt) of
notices of withdrawal will be determined by the Fund in its sole discretion,
which determination shall be final and binding. Shares properly withdrawn shall
not thereafter be deemed to be tendered for purposes of the Offer. However,
withdrawn Shares may be retendered by following one of the procedures described
in Section 2 prior to the Expiration Date.

     6. PAYMENT FOR SHARES. For purposes of the Offer, the Fund will be deemed
to have accepted for payment (and thereby purchased) Shares that are tendered as
of the time that it gives, if and when it gives, oral or written notice to the
Transfer Agent of its election to purchase such Shares. Upon the terms and
subject to the conditions of the Offer, the Fund will accept for payment (and
thereby purchase) promptly after the Expiration Date Shares properly tendered.

     As directed by the Fund, the Transfer Agent will send payment for the
Shares directly to tendering shareholders, or in the case of tendering
shareholders electing an exchange in lieu of cash, directly to the Class B share
account of the designated AIM Funds. Certificates for Shares not purchased, or
for Shares not tendered included in certificates forwarded to the Transfer
Agent, will be returned promptly following the termination, expiration or
withdrawal of the Offer, without expense to the tendering shareholder.

     The Fund will pay all transfer taxes, if any, payable on the transfer to it
of Shares purchased pursuant to the Offer. If tendered certificates are
registered in the name of any person other than the person signing the

                                        6
<PAGE>   7

Letter of Transmittal, the amount of any such transfer taxes (whether imposed on
the registered holder or such other person) payable on account of the transfer
to such person will be deducted from the purchase price unless satisfactory
evidence of the payment of such taxes, or exemption therefrom, is submitted. The
Fund will not pay any interest on the purchase price under any circumstances.

     7. CERTAIN CONDITIONS OF THE OFFER. The Fund shall not be required to
accept for payment or to pay for any Shares tendered, and may terminate or amend
the Offer or may postpone the acceptance for payment of or payment for Shares
tendered, if: (1) such purchases would impair the Fund's status as a regulated
investment company under the Internal Revenue Code of 1986, as amended (the
"Code") (which would cause the Fund's income to be taxed at the corporate level
in addition to the taxation of shareholders who receive dividends from the
Fund); (2) in the judgment of the Board, the Portfolio would not be able to
liquidate portfolio securities in a manner that is orderly and consistent with
the Portfolio's investment objective and policies in order to purchase interests
in the Portfolio tendered by the Fund to effect the Offer; or (3) there is, in
the judgment of the Board, any (a) legal action or proceeding instituted or
threatened challenging the Offer or otherwise materially adversely affecting the
Fund, (b) declaration of a banking moratorium by federal or state authorities or
any suspension of payment by banks in the United States or New York State, that
is material to the Fund, (c) limitation imposed by federal or state authorities
on the extension of credit by lending institutions, (d) commencement of war,
armed hostilities or other international or national calamity directly or
indirectly involving the United States that is material to the Fund, or (e)
other event or condition that would have a material adverse effect on the Fund
or its shareholders if Shares tendered pursuant to the Offer were purchased.

     If the Fund determines to amend the Offer or to postpone the acceptance for
payment of or payment for Shares tendered, it will, to the extent necessary,
extend the period of time during which the Offer is open as provided in Section
15. Moreover, if any of the foregoing conditions is modified or waived in whole
or in part at any time, the Fund will promptly make a public announcement of
such modification or waiver and may, depending on the materiality of the
modification or waiver, extend the Offer period as provided in Section 15.

     8. PURPOSE OF THE OFFER. The Fund does not currently believe there will be
an active secondary market for its Shares. The Board has determined that it
would be in the best interest of shareholders for the Fund to take action to
attempt to provide liquidity to shareholders. To that end, the Board presently
intends each quarter to consider the making of a tender offer to purchase all or
a portion of the Fund's Shares at NAV. The Fund will at no time be required to
make any such tender offer.

     NEITHER THE FUND NOR THE BOARD MAKES ANY RECOMMENDATION TO ANY SHAREHOLDER
AS TO WHETHER TO TENDER OR REFRAIN FROM TENDERING ANY OR ALL OF SUCH
SHAREHOLDER'S SHARES AND HAS NOT AUTHORIZED ANY PERSON TO MAKE ANY SUCH
RECOMMENDATION. SHAREHOLDERS ARE URGED TO EVALUATE CAREFULLY ALL INFORMATION IN
THE OFFER, CONSULT THEIR OWN INVESTMENT AND TAX ADVISORS AND MAKE THEIR OWN
DECISIONS WHETHER TO TENDER SHARES AND, IF SO, HOW MANY SHARES TO TENDER.

     9. CERTAIN EFFECTS OF THE OFFER. The purchase of Shares pursuant to the
Offer will have the effect of increasing the proportionate interest in the Fund
of shareholders who do not tender their Shares. If you retain your Shares,
however, you will be subject to any increased risks that may result from the
reduction in the Fund's aggregate assets resulting from payment for the Shares,
including, for example, the potential for greater volatility due to decreased
diversification of the Portfolio and higher expenses. However, the Fund believes
that those risks will be reduced to the extent new Shares of the Fund are sold.
All Shares purchased by the Fund pursuant to the Offer will be retired by the
Board.

     10. SOURCE AND AMOUNT OF FUNDS. The aggregate purchase price if 3,800,000
Shares are tendered and accepted for payment pursuant to the Offer will be
approximately $37,202,000. The Fund expects to finance the Offer through cash on
hand and through borrowings under the line of credit established by the Fund and
certain other AIM Funds. Currently, the Fund and certain other AIM Funds have a
committed, unsecured line of credit with a syndicate of banks including The
Chase Manhattan Bank, as Administrative Agent, and State Street Bank and Trust
Company, as Operations Agent in the maximum aggregate principal amount of

                                        7
<PAGE>   8

$1,000,000,000. The interest paid under the line of credit is based on one of
the following rates: (i) an adjusted Eurodollar rate based on the London
InterBank Offered Rate plus a reserve percentage established by the Federal
Reserve System plus 0.40%; (ii) ABR, which is, for any day, a rate per annum
(rounded upwards, if necessary, to the next 1/16 of 1%) equal to the greater of
(a) the prime rate in effect on such day and (b) the federal funds rate in
effect on such day plus 1/2 of 1%; (iii) the federal funds rate plus 0.40%; or
(iv) a swing line rate, which is equal to the federal funds rate plus 0.40%. The
Fund expects to repay any amounts borrowed under the line of credit with the
proceeds of sales of additional Fund Shares or sales of the underlying
securities held by Floating Rate Portfolio (the "Portfolio").

     The Fund invests its assets in the Portfolio. In the event that the number
of tendered Shares significantly exceeds 3,800,000 and the Fund determines to
increase the number of Shares sought in the Offer, it may be necessary to sell
underlying securities held by the Portfolio and to conduct a simultaneous tender
offer at the Portfolio level to provide the Fund with additional liquidity.
Under these circumstances, the Fund would tender a portion of its interest in
the Portfolio sufficient to provide the additional liquidity necessary to effect
the Offer.

     Under the Investment Company Act of 1940, as amended (the "1940 Act"), the
Fund is not permitted to incur indebtedness unless immediately after such
incurrence the Fund has an asset coverage of 300% of the aggregate outstanding
principal balance of indebtedness. Additionally, under the 1940 Act the Fund may
not declare any dividend or other distribution upon any class of its capital
stock, or purchase any such capital stock, unless the aggregate indebtedness of
the Fund has, at the time of the declaration of any such distribution or at the
time of any such purchase, an asset coverage of at least 300% after deducting
the amount of such distribution or purchase price, as the case may be. If, in
the judgment of the Board, there is not sufficient liquidity of the assets of
the Fund, or availability of funds from borrowings, to pay for tendered Shares,
the Fund may terminate the Offer.

     11. SUMMARY OF SELECTED FINANCIAL INFORMATION. Set forth below is a summary
of selected financial information for the Fund for the year ended December 31,
1998. More comprehensive financial information is included in the Fund's annual
audited financial statements, which have been filed as an exhibit to the
Schedule 13E-4 filed with the Securities and Exchange Commission (the "SEC")
in connection with the Offer. The summary of selected financial information

     12. CERTAIN INFORMATION ABOUT THE FUND. The Fund is a continuously offered,
non-diversified, closed-end management investment company registered under the
1940 Act. The Fund was incorporated under the name "GT Global Floating Rate
Fund, Inc." in the State of Maryland on December 4, 1996 and is authorized under
Maryland law to do business as "AIM Floating Rate Fund." The Fund's investment
objective is to provide as high a level of current income and preservation of
capital as is consistent with investment in senior secured corporate loans
("Corporate Loans") and senior secured debt securities ("Corporate Debt
Securities"). The Fund seeks to achieve its objective by investing all of its
investable assets in the Portfolio, a separate, non-diversified, closed-end
management investment company that has the same investment objective as the
Fund. The Portfolio's investments primarily take the form of assignments of, or
participations in, Corporate Loans made by banks and other financial
institutions and Corporate Debt Securities. It is anticipated that the Corporate
Loans and Corporate Debt Securities will pay interest at rates that float or
reset at a margin above a generally recognized base lending rate such as LIBOR
or the prime rate of a designated U.S. bank. The Portfolio is managed by AIM
Advisors and is sub-advised by INVESCO Senior Secured Management, Inc. ("INVESCO
SSM"), a subsidiary of INVESCO (NY).

                                        9

     Except for the issuance by the Fund of approximately 1,956,854 Shares
during the past 40 business days, all at prices equal to NAV on the date of sale
and the Fund's purchase of approximately 1,131,033 Shares in its last offer to
purchase, which expired on June 11, 1999, there have not been any transactions
involving the Shares of the Fund that were effected during the past 40 business
days by the Fund, any executive officer or director of the Fund, any person
controlling the Fund, any executive officer or director of any corporation
ultimately in control of the Fund or by any associate or subsidiary of any of
the foregoing including any executive officer or director of any such
subsidiary.

     The principal executive offices of the Fund are located at 11 Greenway
Plaza, Suite 100, Houston, Texas 77046-1173.

     13. ADDITIONAL INFORMATION. The Fund has filed a statement on Schedule
13E-4 with the SEC which includes certain additional information relating to the
Offer. Such material may be inspected and copied at prescribed rates at the
SEC's public reference facilities at 450 Fifth Street, N.W., Washington, D.C.
20549; Seven World Trade Center, New York, New York 10048; and Room 3190, 500
West Madison Street, Suite 1400, Chicago, Illinois 60661. Copies of such
material may also be obtained by mail at prescribed rates from the Public
Reference Branch of the SEC at 450 Fifth Street, N.W., Washington, D.C. 20549.

     14. CERTAIN FEDERAL INCOME TAX CONSEQUENCES. The following discussion is a
general summary of the federal income tax consequences of a sale of Shares
pursuant to the Offer. You should consult your own tax adviser for a complete
description of those consequences to you.

     A sale of Shares pursuant to the Offer (regardless whether any of the cash
proceeds thereof are invested in Class B shares of an AIM Fund (see Section 4))
will be a taxable transaction for federal income tax purposes, either an
"exchange" or, under certain circumstances, a "dividend." In general, the
transaction should be treated as an exchange of the tendered Shares under
section 302 of the Code if the payment for the Shares (1) is "substantially
disproportionate" with respect to the shareholder, (2) results in a "complete
redemption" of the shareholder's interest in the Fund, or (3) is "not
essentially equivalent to a dividend" with respect to the shareholder. A
"substantially disproportionate" distribution generally requires a reduction of
at least 20% in the shareholder's proportionate interest in the Fund after all
Shares are tendered. A "complete redemption" of a shareholder's interest
generally requires that all Shares directly owned by or attributed to the
shareholder under section 318 of the Code be disposed of. A distribution "not
essentially equivalent to a dividend" requires that there be a "meaningful
reduction" in the shareholder's interest, which should occur if the shareholder
has a minimal interest in the Fund, exercises no control over Fund affairs and
suffers a reduction in his proportionate interest in the Fund.

     If any of these three tests for exchange treatment is met, you will
recognize gain or loss on the Fund's purchase of your Shares equal to the
difference between the amount of cash you receive for those Shares (including
any cash used to purchase Class B shares of AIM Funds) and your adjusted tax
basis for them. That gain or loss will be a capital gain or loss if you held the
Shares as capital assets.

     If none of the tests for exchange treatment can be met, you will be treated
as having received a dividend, a return of capital and/or a capital gain,
depending on (1) whether the Fund has sufficient earnings and profits to support
a dividend and (2) your tax basis for the Shares. To the extent the sale of your
Shares is treated as a dividend, your tax basis for the tendered Shares will be
transferred to any remaining Shares you continue to hold. If the sale of Shares
pursuant to the Offer is treated as a dividend to any tendering shareholder, a
constructive dividend may result to a non-tendering shareholder whose
proportionate interest in the Fund's earnings and assets is increased as a
result of the tender.

     Accordingly, the difference between dividend and exchange treatment is
important with respect to the amount and character of income that tendering
shareholders are deemed to receive. In addition, while the marginal federal tax
rates for dividends and capital gains remain the same for corporate
shareholders, the top federal tax rate on ordinary income of individuals (39.6%)
exceeds the maximum federal tax rates on their long-term capital gains -- 20%
for individuals' net capital gain recognized on securities held for more than
one year.

     The Transfer Agent generally will be required to withhold 31% of the gross
proceeds payable to an individual or certain other noncorporate shareholder
pursuant to the Offer unless the shareholder provides a taxpayer identification
number and certifies under penalties of perjury (1) that such number is correct
and (2) either that (a) the shareholder is exempt from backup withholding, (b)
the shareholder is not otherwise subject to backup withholding as a result of a
failure to report all interest or dividends, or (c) the Internal Revenue Service
has notified the shareholder that the shareholder is no longer subject to backup
withholding. Foreign shareholders may be required to provide the Transfer Agent
with a completed Form W-8, available from the Transfer Agent, in order to avoid
31% backup withholding.

     Unless a reduced rate of withholding or a withholding exemption is
available under an applicable tax treaty, a shareholder who is a nonresident
alien or a foreign entity may be subject to a 30% U.S. withholding tax on the
gross proceeds received by the shareholder from the sale of Shares pursuant to
the Offer if the proceeds are treated as a dividend under the rules described
above. Foreign shareholders should consult their tax advisors regarding
application of these withholding rules.

     15. EXTENSION OF TENDER PERIOD; TERMINATION; AMENDMENTS. The Fund reserves
the right, at any time and from time to time, to extend the period of time
during which the Offer is pending by making a public announcement thereof. If
the Fund so elects to extend the tender period, the NAV for the Shares tendered
will be determined as of the close of regular trading on the New York Stock
Exchange on the Expiration Date, as extended. During any such extension, all
Shares previously tendered and not purchased or withdrawn will remain subject to
the Offer. The Fund also reserves the right, at any time and from time to time
up to and including the Expiration Date, to (a) terminate the Offer and not to
purchase or pay for any Shares, and (b) amend the Offer in any respect, by
making a public announcement. Such public announcement will be issued no later
than 9:00 a.m., New York City time, on the next business day after the
previously scheduled Expiration Date and will disclose the approximate number of
Shares tendered as of that date. Without limiting the manner in which the Fund
may choose to make a public announcement of extension, termination or amendment,
except as provided by applicable law or regulation (including Rule 13e-4(e)(2)
under the Exchange Act), the Fund shall have no obligation to publish, advertise
or otherwise communicate any such public announcement, other than by making a
release to the Dow Jones News Service.

     If the Fund materially changes the terms of the Offer or the information
concerning the Offer, or if it waives a material condition of the Offer, the
Fund will extend the Offer to the extent required by Rule 13e-4 under the
Exchange Act. These rules require that the minimum period during which an offer
must remain open following material changes in the terms of the Offer or
information concerning the Offer (other than a change in price or a change in
percentage of securities sought) will depend on the facts and circumstances,
including the relative materiality of such terms of information. If (i) the Fund
increases or decreases the consideration to be paid for Shares, or the Fund
increases the number of Shares being sought by an amount exceeding 2% of the
outstanding Shares, or the Fund decreases the number of Shares being sought and
(ii) the Offer is scheduled to expire at any time earlier than the expiration of
a period ending on the tenth business day from, and including, the date that
notice of such increase or decrease is first published, sent or given, the Offer
will be extended at least until the expiration of such period of ten business
days.

     16. MISCELLANEOUS. The Offer is not being made to, nor will tenders be
accepted from, shareholders in any jurisdiction in which the Offer or its
acceptance would not comply with the securities laws of such jurisdiction. The
Fund is not aware of any jurisdiction in which the Offer or tenders pursuant
thereto would not be in compliance with the laws of such jurisdiction. However,
the Fund reserves the right to exclude shareholders from the Offer in any
jurisdiction in which it is asserted that the Offer cannot lawfully be made. The
Fund believes such exclusion is permissible under applicable tender offer rules,
provided the Fund makes a good faith effort to comply with any state law deemed
applicable to the Offer. In any jurisdiction the securities laws of which
require the Offer to be made by a licensed broker or dealer, the Offer shall be
deemed to be made on the Fund's behalf by one or more registered brokers or
dealers licensed under the laws of such jurisdiction.

LADIES AND GENTLEMEN:

     Pursuant to the Offer to Purchase dated August 12, 1999 (the "Offer to
Purchase"), receipt of which is hereby acknowledged, the undersigned hereby
tenders to AIM Floating Rate Fund, a closed-end investment company incorporated
under the laws of the State of Maryland (the "Fund"), the shares described below
of its common stock, par value $.001 per share (the "Shares"), at a price equal
to the net asset value per Share ("NAV") calculated on the Expiration Date (as
defined in the Offer to Purchase), in cash, less any applicable Early Withdrawal
Charge, upon the terms and conditions set forth in the Offer to Purchase and
this Letter of Transmittal.

     The undersigned hereby sells to the Fund all Shares tendered hereby that
are purchased pursuant to the Offer and hereby irrevocably constitutes and
appoints A I M Fund Services, Inc. (the "Transfer Agent") as attorney in fact of
the undersigned, with full power of substitution (such power of attorney being
deemed to be an irrevocable power coupled with an interest), to present such
Shares and any Share certificates for cancellation of such Shares on the Fund's
books. The undersigned hereby warrants that the undersigned has full authority
to sell the Shares tendered hereby and that the Fund will acquire good title
thereto, free and clear of all liens, charges, encumbrances, conditional sales
agreements or other obligations relating to the sale thereof, and not subject to
any adverse claim, when and to the extent the same are purchased by it. Upon
request, the undersigned will execute and deliver any additional documents
necessary to complete the sale in accordance with the terms of the Offer.

information should be listed on a separate signed schedule attached hereto.

     5. Partial Tenders. If fewer than all of the Shares evidenced by any

represented by certificate(s) listed are deemed to have been tendered unless
otherwise indicated.

     6. Signatures on Letter of Transmittal, Authorization and Endorsements.

     (a) If the Letter of Transmittal is signed by the registered holder of the
Shares tendered hereby, the signature(s) must correspond with the name(s) in
which the Shares are registered.

     (b) If the Shares are held of record by two or more joint holders, all such

     (c) If any tendered Shares are registered in different names, it will be
necessary to complete, sign and submit as many separate Letters of Transmittal
as there are different registrations of Shares.

     (d) When this Letter of Transmittal is signed by the registered holder(s)
of the Shares listed and, if applicable, of the certificates transmitted hereby,
no endorsements of certificates or separate authorizations are required.

     (e) If this Letter of Transmittal or any certificates or authorizations are
signed by trustees, executors, administrators, guardians, attorneys in fact,

capacity, such persons should so indicate when signing, and must submit proper
evidence satisfactory to the Fund of their authority so to act.

     (f) Shareholders holding shares in an Individual Retirement Account ("IRA")
that mail or deliver a Letter of Transmittal to tender Shares must also provide
the Transfer Agent with a completed IRA distribution form.

     7. Transfer Taxes. The Fund will pay all transfer taxes, if any, payable on
the transfer to it of Shares purchased pursuant to the Offer. If tendered
certificates are registered in the name of any person other than the person(s)
signing this Letter of Transmittal, the amount of any transfer taxes (whether
imposed on the registered holder or such other persons) payable on account of
the transfer to such person will be deducted from the purchase price unless
satisfactory evidence of the payment of such taxes, or exemption therefrom, is
submitted.

     8. Irregularities. All questions as to the validity, form, eligibility
(including time of receipt) and acceptance of any tender of Shares will be
determined by the Fund, in its sole discretion, which determination shall be
final and binding. The Fund reserves the absolute right to reject any or all
tenders determined by it not to be in appropriate form or the acceptance of or
payment for which would, in the opinion of counsel for the Fund, be unlawful.
The Fund also reserves the absolute right to waive any of the conditions of the
Offer or any defect in any tender with respect to any particular Shares or any
particular shareholder, and the Fund's interpretations of the terms and
conditions of the Offer (including these instructions) will be final and
binding. Unless waived, any defects or irregularities in connection with tenders
must be cured within such time as the Fund shall determine. Tendered Shares will
not be accepted for payment unless the defects and irregularities have been
cured within such time or waived. Neither the Fund, A I M Advisors, Inc.,
INVESCO Senior Secured Management, Inc., nor the Transfer Agent, nor any other
person shall be obligated to give notice of defects or irregularities in
tenders, nor shall any of them incur any liability for failure to give any such
notice.

     9. Important Tax Information. A shareholder whose tendered Shares are
accepted for payment is required by law to provide the Transfer Agent (as payer)
with his or her correct taxpayer identification number, which is accomplished by
completing and signing the Signature Form.

                             AIM FLOATING RATE FUND
                          11 Greenway Plaza, Suite 100
                           Houston, Texas 77046-1173

DEAR SHAREHOLDER:

     As you know, AIM Floating Rate Fund (the "Fund") commenced operations on
May 1, 1997. The performance of the Fund has been positive: The yield since
inception calculated as a percentage of the net asset value as of June 30, 1999,
is 7.11%. The net asset value (NAV) of the Fund over that time period has
fluctuated between $10.02 and $9.82. In spite of recent market conditions and
subsequent NAV decreases, we continue to be satisfied with the overall credit
quality of the assets we own in the Fund.

     The Fund's Shares are not publicly traded. However, each quarter the Fund's
Board of Directors (the "Board") will consider whether to make a tender offer
for all or a portion of the Fund's issued and outstanding shares (the "Shares")
to provide liquidity for the Fund's shareholders. For the third quarter of 1999,
the Board has determined to purchase up to 3,800,000 of the Fund's Shares.

     Accordingly, we are enclosing a copy of the Fund's Offer to Purchase (the
"Offer to Purchase"), dated August 12, 1999. The Offer to Purchase is for cash
at net asset value ("NAV") per Share as of the expiration date of the offer,
less applicable "early withdrawal charges." Certain selected financial
information with respect to the Fund is also set forth in the Offer to Purchase.
We also enclose a Letter of Transmittal (the "Letter of Transmittal") for use by
record holders of Shares. You should read each of these documents carefully.

     If, after reviewing the information set forth in the Offer to Purchase and
Letter of Transmittal, you wish to tender Shares for purchase by the Fund,
please contact your broker, dealer or other nominee to effect the tender for
you. If you are the record owner of the Shares and intend to tender your Shares
yourself directly to the Transfer Agent, you should follow the instructions
contained in the Offer to Purchase, and the enclosed Letter of Transmittal,
which must be completed by you.

     Neither the Fund nor its Board of Directors is making any recommendation to
any holder of Shares as to whether to tender Shares. Each shareholder is urged
to consult his or her broker or tax adviser before deciding whether to tender
any Shares.

     The Fund's NAV on August 6, 1999 was $9.79 per Share. The Fund publishes
its NAV each week in the Wall Street Journal. It appears under the sub-heading
"Loan Participation Funds" within the listings of mutual funds and closed-end
funds. You may also obtain current NAV quotations by calling A I M Fund
Services, Inc., the Fund's Transfer Agent, at (800) 959-4246.

amount equal to the stated or determinable amount of the primary obligation in
respect of which such Guarantee Obligation is made and (b) the maximum amount
for which such guaranteeing person may be liable pursuant to the terms of the
instrument embodying such Guarantee Obligation, unless such primary obligation

respective Note on behalf of its portfolios, as Borrowers, and that such
portfolios will utilize the Loans thus made on their behalf. Unless otherwise
noted herein, no Fund shall make any designation, provide any notice or take any
other action on behalf of any Borrower unless such Borrower is an investment
portfolio of the Fund.


                    SECTION 2. AMOUNT AND TERMS OF COMMITMENTS

                  2.1 Commitments. (a) Subject to the terms and conditions
hereof; each Lender severally agrees to make revolving credit loans ("Loans") to
each Borrower, from time to


                                      -11-
<PAGE>   16
time during the Commitment Period in an aggregate principal amount outstanding
at any one time not to exceed the amount of such Lender's Commitment. During the
Commitment Period, a Borrower may use the Commitments available to it by
borrowing, prepaying Loans in whole or in part, and reborrowing, all in
accordance with the terms and conditions hereof.

                  (b) The Loans may from time to time be (i) Eurodollar Loans,
(ii) ABR Loans, (iii) Federal Funds Rate Loans or (iv) a combination thereof; as
determined by a Borrower and notified to the Operations Agent in accordance with
subsection 2.2, provided that no Loan shall be made as a Eurodollar Loan after
the day that is one month prior to the Termination Date.

                  2.2 Procedure for Borrowing. A Borrower may borrow under the
Commitments during the Commitment Period on any Business Day, provided that the
appropriate Fund on behalf of such Borrower shall give the Operations Agent
irrevocable notice (which notice must be received by the Operations Agent prior
to 1:00 P.M., New York City time on the requested Borrowing Date with respect to
ABR Loans and Federal Funds Rate Loans and on the date three Business Days prior
to the Borrowing Date with respect to Eurodollar Loans) specifying (i) the
Borrower, (ii) the amount to be borrowed, (iii) the requested Borrowing Date,
(iv) subject to subsection 2.1(b), whether the borrowing is to be of Eurodollar
Loans, ABR Loans, Federal Funds Rate Loans or a combination thereof and (v) the
Maturity Date for the borrowing. The aggregate amount of all borrowings by the
Borrowers under the Commitments on any Borrowing Date shall be in an amount
equal to (x) in the case of Federal Funds Rate Loans or Eurodollar Loans,
$5,000,000 or a whole multiple of $500,000 in excess thereof (or, if the then
Available Commitments are less than $5,000,000, such lesser amount), and (y) in
the case of ABR Loans, $1,000,000 or a whole multiple of $500,000 in excess
thereof (or, if the then Available Commitments are less than $1,000,000, such
lesser amount). Upon receipt of any such notice from the appropriate Fund on
behalf of a Borrower, the Operations Agent shall promptly notify each Lender
thereof. Each Lender will make the amount of its pro rata share of each
borrowing available to the Operations Agent for the account of such Borrower at
the office of the Operations Agent specified in subsection 9.2 prior to 2:00
P.M., New York City time, on the Borrowing Date requested by such Borrower in
funds immediately available to the Operations Agent. Such borrowing will then be
made available to such Borrower by the Operations Agent crediting the account of
the appropriate Borrower on the books of such office with the aggregate of the
amounts made available to the Operations Agent by the Lenders and in like funds
as received by the Operations Agent; provided that if, on the Borrowing Date of
any Loans of a Borrower, any Swing Line Loans to such Borrower shall be
outstanding, the proceeds of such Loans to such Borrower shall first be applied
to pay in full such Swing Line Loans, with any remaining proceeds to be made
available to such Borrower as provided above.

                  2.3 Commitment Fee: Other Fees. (a) Each Borrower severally
agrees to pay to the Operations Agent for the account of each Lender such
Borrower's pro rata portion (as allocated by AIM in its reasonable discretion)
of the commitment fee for the Commitment Period, computed at the rate of 0.09 of
1% per annum, in each case on the average daily amount


                                      -12-
<PAGE>   17
of the Available Commitment of such Lender during the period for which payment
is made, payable quarterly in arrears on the 15th day of each April, July,
October and January, and on the Termination Date or such earlier date as the
Commitments shall terminate as provided herein, commencing on the first of such
dates to occur after the date hereof. Solely for the purpose of calculating the
commitment fee, Swing Line Loans will not be deemed a utilization of the
Commitments of all Lenders.

                  (b) Each Borrower severally agrees to pay the Agents for the
accounts of the respective Agents the fees separately to agreed to. Such fees
shall be allocated by AIM in its reasonable discretion among the Borrowers
according to each Borrower's pro rata portion of such fees.

                  2.4 Termination or Reduction of Commitments. (a) Each Borrower
shall have the right, upon not less than three Business Days' notice to the
Administrative Agent by the appropriate Fund on behalf of such Borrower, to
terminate the Commitments with respect to such Borrower. All Borrowers, acting
together, shall have the right, upon not less than three Business Days' notice
to the Administrative Agent by all of the appropriate Funds, from time to time,
to terminate or reduce the amount of the Commitments. Any such reduction shall
be in an aggregate amount equal to $1,000,000 or a whole multiple of $1,000,000
in excess thereof. To the extent, if any, that the amount of the Loans then
outstanding exceeds the amount of the Commitments as then reduced, the Borrowers
shall be required to make a prepayment of a portion of the Loans then
outstanding equal to such excess amount. Any such termination of the Commitments
of a Borrower or of all Borrowers shall be irrevocable and shall be accompanied
by prepayment in full of the Loans of such Borrower or Borrowers then
outstanding.

                  (b) Interest accrued on the amount of any partial prepayment
pursuant to this subsection 2.4 to the date of such partial prepayment, together
with any amounts owing pursuant to Section 2.14, shall be paid on the date of
such partial prepayment. In the case of the termination of the Commitments,
interest accrued on the amount of any prepayment relating thereto, together with
any amounts owing pursuant to Section 2.14, and any unpaid commitment fee
accrued hereunder shall be paid on the date of such termination.

                  2.5 Repayment of Loans: Evidence of Debt. (a) Each Borrower
hereby severally unconditionally promises to pay to the Operations Agent for the
account of each Lender the then unpaid principal amount of each Loan of such
Lender to such Borrower on the Maturity Date for such Loan (or such earlier date
on which the Loans become due and payable pursuant to Section 7). Each Borrower
hereby further severally agrees to pay interest on the unpaid principal amount
of the Loans to such Borrower from time to time outstanding from the date hereof
until payment in full thereof at the rates per annum, and on the dates, set
forth in subsection 2.7.

                  (b) Each Lender shall maintain in accordance with its usual
practice an account or accounts evidencing indebtedness of each Borrower to such
Lender resulting from


                                      -13-
<PAGE>   18
each Loan of such Lender from time to time, including the amounts of principal
and interest payable and paid to such Lender from time to time under this
Agreement.

                  (c) The Operations Agent shall maintain the Register pursuant
to subsection 9.6 (d) (with a copy, as requested to the Administrative Agent),
and a subaccount therein for each Lender, in which shall be recorded (i) the
amount of each Loan made hereunder, (ii) the amount of any principal or interest
due and payable or to become due and payable from each Borrower to each Lender
hereunder and (iii) both the amount of any sum received by the Operations Agent
hereunder from each Borrower and each Lender's share thereof.

                  (d) The entries made in the Register and the accounts of each
Lender maintained pursuant to subsection 2.5(b) shall, to the extent permitted
by applicable law, be prima facie evidence of the existence and amounts of the
obligations of the Borrower therein recorded, provided, however, that the
failure of any Lender or the Operations Agent to maintain the Register or any
such account, or any error therein, shall not in any manner affect the
obligation of any Borrower to repay (with applicable interest) the Loans made to
such Borrower by such Lender in accordance with the terms of this Agreement.

                  (e) Each Fund agrees that, upon request to the Administrative
Agent, by any Lender, such Fund will execute and deliver to such Lender a
promissory note of the Fund on its own behalf or on behalf of a Borrower (as
applicable) evidencing the Loans of such Lender to such Borrower, substantially
in the form of Exhibit A with appropriate insertions as to date and principal
amount (a "Note").

                  (f) The obligations of each Borrower under its Notes shall be
several and not joint. Notwithstanding anything to the contrary contained in
this Agreement, the parties hereto acknowledge and agree that the sole source of
payment of the obligations of each Borrower hereunder, including, without
limitation, the principal of and interest on each Loan made hereunder to any
Borrower, the fees payable pursuant to Section 2.3 and any other amounts payable
hereunder shall be such Borrower and the revenues and assets of such Borrower,
and not the revenues and assets of any other Borrower or the revenues and assets
of the Fund issuing shares representing an interest in such Borrower (except to
the extent of such Borrower) or the revenues and assets of AIM or any of its
Affiliates (other than such Borrower).

                  2.6 Optional and Mandatory Prepayments. (a) Each Borrower may
at any time prepay the Loans made to it, in whole or in part, without premium or
penalty, provided that the appropriate Fund on behalf of such Borrower shall
give the Operations Agent irrevocable notice (which notice must be received by
the Operations Agent prior to 1:00 P.M. New York City time on the prepayment
date with respect to ABR Loans and Federal Funds Rate Loans and on the date
three Business Days prior to the prepayment date with respect to Eurodollar
Loans), specifying the date and amount of prepayment. Upon receipt of any such
notice the Operations Agent shall promptly notify each Lender thereof. If any
such notice is given, the amount specified in such notice shall be due and
payable on the date specified therein, together with


                                      -14-
<PAGE>   19
accrued interest on the amount prepaid and any amounts payable pursuant to
subsection 2.14. Optional partial prepayments shall be in an aggregate principal
amount equal to $1,000,000 or a whole multiple of $500,000 in excess thereof.

                  (b) If at any time and from time to time, either (i) for each
Borrower other than a Designated Borrower, the Asset Coverage Ratio for such
Borrower shall be less than 3 to 1 or (ii) for any Designated Borrower, the
Asset Coverage Ratio for such Designated Borrower shall be less than the
Designated Borrower Asset Coverage Ratio for such Designated Borrower, such
Borrower or Designated Borrower, as applicable, shall immediately repay the
Loans to such Borrower or Designated Borrower, as applicable, together with
accrued interest on the amount prepaid and any amounts payable pursuant to
subsection 2.14, to the extent necessary to ensure that the Asset Coverage Ratio
of such Borrower or Designated Borrower, as applicable, is not less than 3 to 1,
in the case of each Borrower other than a Designated Borrower, or is not less
than the Designated Borrower Asset Coverage Ratio, in the case of each
Designated Borrower.

                  (c) if at any time and from time to time, the aggregate amount
of Loans made to a Borrower then outstanding exceeds the borrowing limits
provided in such Borrowers Prospectus or under the 1940 Act, such Borrower shall
immediately prepay such Loans to the extent necessary to ensure that the
aggregate amount of Loans made to such Borrower then outstanding does not exceed
such limits, together with accrued interest on the amount prepaid and any
amounts payable pursuant to subsection 2.14.

                  2.7 Interest Rates and Payment Dates. (a) Each Eurodollar Loan
shall bear interest for each day during the Interest Period with respect thereto
at a rate per annum equal to the Eurodollar Rate determined for such day plus
the Applicable Margin.

                  (b) Each ABR Loan shall bear interest at a rate per annum
equal to the ABR plus the Applicable Margin.

                  (c) Each Federal Funds Rate Loan shall bear interest at a rate
per annum equal to the Federal Funds Rate plus the Applicable Margin.

                  (d) If all or a portion of (i) the principal amount of any
Loan, (ii) any interest payable thereon or (iii) any commitment fee or other
amount payable hereunder shall not be paid when due (whether at the stated
maturity, by acceleration or otherwise), such overdue amount shall bear interest
at a rate per annum which is (x) in the case of overdue principal, the rate that
would otherwise be applicable thereto pursuant to the foregoing provisions of
this subsection plus 2% per annum or (y) in the case of overdue interest,
commitment fee or other amount, the rate described in paragraph (c) of this
subsection plus 2% per annum, in each case from the date of such non-payment
until such amount is paid in full (as well after as before judgment).


                                      -15-
<PAGE>   20
                  (e) Interest shall be payable in arrears on each Interest
Payment Date, provided that interest accruing pursuant to paragraph (d) of this
subsection shall be payable from time to time on demand.

                  2.8 Computation of Interest and Fees. (a) Commitment fees and
interest shall be calculated on the basis of a 360-day year for the actual days
elapsed, except that in the case of ABR Loans based on the Prime Rate interest
shall be calculated on the basis of a 365- or 366-day year, as applicable, for
the actual days elapsed. Any change in the interest rate on a Loan resulting
from a change in either the Prime Rate or in the Federal Funds Rate shall become
effective as of the opening of business on the day on which such change becomes
effective. The Operations Agent shall as soon as practicable notify the Borrower
and the Lenders of the effective date and the amount of each such change in
interest rate.

                  (b) Each determination of an interest rate by the Operations
Agent pursuant to any provision of this Agreement shall be conclusive and
binding on each Borrower and the Lenders in the absence of manifest error.

                  2.9 Inability to Determine Interest Rate. If on a Borrowing
Date:

                  (a) the Operations Agent shall have determined (which
         determination shall be conclusive and binding upon the Borrowers) that,
         by reason of circumstances affecting the relevant market, adequate and
         reasonable means do not exist for ascertaining the Eurodollar Rate for
         such Interest Period, or

                  (b) the Operations Agent shall have received notice from the
         Majority Lenders that the Eurodollar Rate determined or to be
         determined for such Interest Period will not adequately and fairly
         reflect the cost to such Lenders (as conclusively certified by such
         Lenders) of making or maintaining their affected Loans during such
         Interest Period,

the Operations Agent shall give telecopy or telephonic notice thereof to the
Borrowers and the Lenders as soon as practicable thereafter. If such notice is
given, any Eurodollar Loans requested to be made shall be made as Federal Funds
Rate Loans. Until such notice has been withdrawn by the Operations Agent, no
further Eurodollar Loans shall be made.

                  2.10 Pro Rata Treatment and Payments. (a) Each borrowing by a
Borrower from the Lenders hereunder, each payment by a Borrower on account of
any commitment fee hereunder and any reduction of the Commitments of the
Lenders, shall be made pro rata according to the respective Commitment
Percentages of the Lenders. Each payment (including each prepayment) by a
Borrower on account of principal of and interest on the Loans shall be made pro
rata according to the respective outstanding principal amounts of the Loans of
such Borrower then held by the Lenders. All payments (including prepayments) to
be made by a Borrower hereunder, whether on account of principal, interest, fees
or otherwise, shall be made


                                      -16-
<PAGE>   21
without set off or counterclaim and shall be made prior to 2:00 P.M., New York
City time, on the due date thereof to the Operations Agent, for the account of
the Lenders or the Swing Line Lender, as the case may be, at the Operations
Agent's office specified in subsection 9.2, in Dollars and in immediately
available funds. The Operations Agent shall distribute such payments to the
Lenders or the Swing Line Lender, as the case may be, promptly upon receipt in
like funds as received. If any payment hereunder becomes due and payable on a
day other than a Business Day, such payment due date shall be extended to the
next succeeding Business Day, and, with respect to payments of principal,
interest thereon shall be payable at the then applicable rate during such
extension.

                  (b) Unless the Operations Agent shall have been notified in
writing by any Lender prior to a borrowing that such Lender will not make the
amount that would constitute its Commitment Percentage of such borrowing
available to the Operations Agent, the Operations Agent may assume that such
Lender is making such amount available to the Operations Agent, and the
Operations Agent may, in reliance upon such assumption, make available to the
appropriate Fund on behalf of the requesting Borrower a corresponding amount. If
such amount is not made available to the Operations Agent by the required time
on the Borrowing Date therefor, such Lender shall pay to the Operations Agent,
on demand, such amount with interest thereon at a rate equal to the Federal
Funds Rate for the period until such Lender makes such amount immediately
available to the Operations Agent. A certificate of the Operations Agent
submitted to any Lender with respect to any amounts owing under this subsection
shall be conclusive in the absence of manifest error. If such Lender's
Commitment Percentage of such borrowing is not made available to the Operations
Agent by such Lender within three Business Days of such Borrowing Date, the
Operations Agent shall also be entitled to recover such amount with interest
thereon at the rate per annum applicable to Federal Funds Rate Loans hereunder,
on demand, from the relevant Borrower.

                  2.11 Illegality. Notwithstanding any other provision herein,
if the adoption of or any change in any Requirement of Law or in the
interpretation or application thereof shall make it unlawful for any Lender to
make or maintain Eurodollar Loans as contemplated by this Agreement, (a) the
commitment of such Lender hereunder to make Eurodollar Loans shall forthwith be
canceled and (b) such Lender's Loans then outstanding as Eurodollar Loans, if
any, shall be converted automatically to Federal Funds Rate Loans on such date
as required by law. If any such conversion of a Eurodollar Loan occurs on a day
which is not the last day of the then current Interest Period with respect
thereto, the Borrower shall pay to such Lender such amounts, if any, as may be
required pursuant to subsection 2.14 as if such Eurodollar Loans had been
prepaid.

                  2.12 Requirements of Law. (a) If the adoption of or any change
in any Requirement of Law (other than changes to a Lender's articles or
certificate of incorporation, bylaws or other organizational documents) or in
the interpretation or application thereof or compliance by any Lender with any
directive from any central bank or other Governmental Authority made subsequent
to the date hereof:


                                      -17-
<PAGE>   22
                  (i) shall subject any Lender to any tax of any kind whatsoever
         with respect to this Agreement, any Note or any Eurodollar Loan by it,
         or change the basis of taxation of payments to such Lender in respect
         thereof (except for Non-Excluded Taxes covered by subsection 2.13 and
         changes in the rate of tax on the overall net income of such Lender);

                  (ii) shall impose, modify or hold applicable any reserve,
         special deposit, compulsory loan or similar requirement against assets
         held by, deposits or other liabilities in or for the account of;
         advances, loans or other extensions of credit by, or any other
         acquisition of funds by, any office of such Lender which is not
         otherwise included in the determination of the Eurodollar Rate
         hereunder; or

                   (iii) shall impose on such Lender any other condition;

and the result of any of the foregoing is to increase the cost to such Lender,
by an amount which such Lender reasonably deems to be material, of making or
maintaining Eurodollar Loans or to reduce any amount receivable hereunder in
respect thereof by an amount which such Lender reasonably deems to be material,
then, in any such case, each Borrower shall promptly pay such Lender such
additional amount or amounts as will compensate such Lender for such increased
cost or reduced amount receivable with respect to such Borrower's Loans.

                  (b) If any Lender shall have determined that the adoption of
or any change in any Requirement of Law regarding capital adequacy or in the
interpretation or application thereof or compliance by such Lender or any
corporation controlling such Lender with any request or directive regarding
capital adequacy (whether or not having the force of law) from any Governmental
Authority made subsequent to the date hereof shall have the effect of reducing
the rate of return on such Lender's or such corporation's capital as a
consequence of its obligations hereunder to a level below that which such Lender
or such corporation could have achieved but for such adoption, change or
compliance (taking into consideration such Lender's or such corporation's
policies with respect to capital adequacy) by an amount deemed by such Lender to
be material, then from time to time, each Borrower shall promptly pay to such
Lender such additional amount or amounts as will compensate such Lender for such
reduction with respect to such Borrower's Loans.

                  (c) If any Lender becomes entitled to claim any additional
amounts pursuant to this subsection, it shall promptly notify the Borrowers
(with a copy to the Administrative Agent) of the event by reason of which it has
become so entitled. A certificate as to any additional amounts payable pursuant
to this subsection submitted by such Lender to the Borrowers (with a copy to the
Administrative Agent) shall be conclusive in the absence of manifest error. The
agreements in this subsection shall survive the termination of this Agreement
and the payment of the Loans and all other amounts payable hereunder.


                                      -18-
<PAGE>   23
                  2.13 Taxes. (a) All payments made by any Borrower under this
Agreement and any Notes shall be made free and clear of; and without deduction
or withholding for or on account of; any present or future income, stamp or
other taxes, levies, imposts, duties, charges, fees, deductions or withholdings,
now or hereafter imposed, levied, collected, withheld or assessed by any
Governmental Authority, excluding net income taxes and franchise taxes (imposed
in lieu of net income taxes) imposed on the Agents or any Lender as a result of
a present or former connection between the Agents or such Lender and the
jurisdiction of the Governmental Authority imposing such tax or any political
subdivision or taxing authority thereof or therein (other than any such
connection arising solely from the Agents or such Lender having executed,
delivered or performed its obligations or received a payment under, or enforced,
this Agreement or any Note). If any such non-excluded taxes, levies, imposts,
duties, charges, fees, deductions or withholdings ("Non-Excluded Taxes") are
required to be withheld from any amounts payable to the Operations Agent or any
Lender hereunder or under any Note, the amounts so payable to the Operations
Agent or such Lender shall be increased to the extent necessary to yield to the
Operations Agent or such Lender (after payment of all Non-Excluded Taxes)
interest or any such other amounts payable hereunder at the rates or in the
amounts specified in this Agreement, provided, however, that a Borrower shall
not be required to increase any such amounts payable to any Lender that is not
organized under the laws of the United States of America or a state thereof if
such Lender fails to comply with the requirements of paragraph (b) of this
subsection. Whenever any Non-Excluded Taxes are payable by a Borrower, as
promptly as possible thereafter such Borrower shall send to the Administrative
Agent for its own account or for the account of such Lender, as the case may be,
a certified copy of an original official receipt received by such Borrower
showing payment thereof. If a Borrower fails to pay any Non-Excluded Taxes when
due to the appropriate taxing authority or fails to remit to the Administrative
Agent the required receipts or other required documentary evidence, such
Borrower shall indemnify the Operations Agent and the Lenders for any
Non-Excluded Taxes paid by the Operations Agent or any Lender and for any
incremental taxes, interest or penalties that may become payable by the
Operations Agent or any Lender as a result of any such failure. The agreements
in this subsection shall survive the termination of this Agreement and the
payment of the Loans and all other amounts payable hereunder.

                  (b) Each Lender that is not incorporated under the laws of the
United States of America or a state thereof shall:

                  (i) deliver to the Funds and the Operations Agent two duly
         completed copies of (A) United States Internal Revenue Service Form
         1001 or 4224, or successor applicable form, as the case may be, and (B)
         Internal Revenue Service Form W-9 or both Internal Revenue Service
         Forms W-8 and W-9, or successor applicable form, as the case may be;

                  (ii) deliver to the Funds and the Operations Agent two further
         copies of any such form or certification on or before the date that any
         such form or certification expires


                                      -19-
<PAGE>   24
         or becomes obsolete and after the occurrence of any event requiring a
         change in the most recent form previously delivered by it to the Funds;
         and

                  (iii) obtain such extensions of time for filing and complete
         such forms or certifications as may reasonably be requested by the
         Funds or the Agents;

unless in any such case an event (including, without limitation, any change in
treaty, law or regulation) has occurred prior to the date on which any such
delivery would otherwise be required which renders all such forms inapplicable
or which would prevent such Lender from duly completing and delivering any such
form with respect to it and such Lender so advises the Funds and the Agents.
Such Lender shall certify (A) in the case of a Form 1001 or 4224, that it is
entitled to receive payments under this Agreement without deduction or
withholding of any United States federal income taxes and (B) in the case of
Forms W-8 and W-9, that it is entitled to an exemption from United States backup
withholding tax. Each Person that shall become a Lender or a Participant
pursuant to subsection 9.6 shall, upon the effectiveness of the related
transfer, be required to provide all of the forms and statements required
pursuant to this subsection, provided that in the case of a Participant such
Participant shall furnish all such required forms and statements to the Lender
from which the related participation shall have been purchased.

                  2.14 Indemnity. Each Borrower severally agrees to indemnify
each Lender and to hold each Lender harmless from any loss or expense which such
Lender may sustain or incur as a consequence of (a) default by such Borrower in
making a borrowing of Eurodollar Loans after the Borrower has given a notice
requesting the same in accordance with the provisions of this Agreement, (b)
default by the Borrower in making any prepayment after the Borrower has given a
notice thereof in accordance with the provisions of this Agreement or (c) the
making of a prepayment of Eurodollar Loans on a day which is not the last day of
an Interest Period with respect thereto. Such indemnification may include an
amount equal to the excess, if any, of (i) the amount of interest which would
have accrued on the amount so prepaid, or not so borrowed, for the period from
the date of such prepayment or of such failure to borrow to the last day of such
Interest Period (or, in the case of a failure to borrow, the Interest Period
that would have commenced on the date of such failure) in each case at the
applicable rate of interest for such Loans provided for herein (excluding,
however, the Applicable Margin included therein, if any) over (ii) the amount of
interest (as reasonably determined by such Lender) which would have accrued to
such Lender on such amount by placing such amount on deposit for a comparable
period with leading banks in the interbank eurodollar market. This covenant
shall survive for twenty-four months after the termination of this Agreement and
the payment of the Loans and all other amounts payable hereunder.

                  2.15 Change of Lending Office. Each Lender agrees that if it
makes any demand for payment under subsection 2.12 or 2.13, it will use its best
efforts (consistent with its internal policy and legal and regulatory
restrictions and so long as such efforts would not be disadvantageous to it, as
determined in its sole discretion) to designate a different lending office


                                      -20-
<PAGE>   25
if the making of such a designation would reduce or obviate the need for a
Borrower to make payments under subsection 2.12 or 2.13.

                  2.16 Swing Line Commitment: Subject to the terms and
conditions hereof; the Swing Line Lender agrees to make available to each
Borrower a portion of the credit otherwise available under the Commitments from
time to time during the Commitment Period by making swing line loans ("Swing
Line Loans") to such Borrower in an aggregate principal amount not to exceed at
any one time outstanding the Swing Line Commitment; provided, however, that the
Swing Line Loans outstanding at any time, when aggregated with the Swing Line
Lender's other outstanding Loans hereunder, may not exceed the Swing Line
Lender's Commitment then in effect; and provided, further however, that on the
date of the making of any Swing Line Loan and while any Swing Line Loan is
outstanding, the sum of the aggregate principal amount of all outstanding Loans
and Swing Line Loans shall not exceed the total Commitments (less the Commitment
of any non-funding Lender referred to in Section 2.10(b)). During the Commitment
Period applicable to each Borrower, such Borrower may use the Swing Line
Commitment by borrowing, repaying and reborrowing, all in accordance with the
terms and conditions hereof. Each Swing Line Loan shall bear interest at a rate
per annum equal to the Federal Funds Rate plus the Applicable Margin.

                  2.17 Procedure for Swing Line Borrowing. Whenever a Borrower
desires that the Swing Line Lender make Swing Line Loans under Section 2.16, the
Borrower (or the Fund of which it is an investment portfolio) shall give the
Swing Line Lender irrevocable telephonic notice confirmed promptly in writing
(which telephonic notice must be received by the Swing Line Lender not later
than 4:00 P.M., New York City time, on the proposed Borrowing Date), specifying
the amount of each requested Swing Line Loan. Each borrowing under the Swing
Line Commitment shall be in an amount equal to $100,000 or an integral multiple
of $50,000 in excess thereof. Upon receipt of any such notice from a Borrower
(or the Fund on its behalf), the Swing Line Lender shall promptly notify the
Operations Agent thereof. The Swing Line Lender shall make the amount of such
borrowing available to the Borrower prior to 5:00 P.M., New York City time, on
the Borrowing Date requested by such Borrower. The proceeds of such Swing Line
Loan will then be made available to such Borrower on such Borrowing Date by the
Swing Line Lender transferring by wire or book entry to the appropriate
custodian of and for the account of such Borrower such Swing Line Loan in
immediately available funds.

                  2.18 Refunding of Swing Line Loans. (a) The Operations Agent,
on the seventh day (or if such day is not a Business Day, the next Business Day
following the seventh day) after the Borrowing Date with respect to any Swing
Line Loans to a Borrower shall, on behalf of such Borrower (and each Borrower
hereby irrevocably directs the Operations Agent to so act on its behalf and with
respect to such Borrower), upon notice given by the Operations Agent no later
than 1:00 P.M., New York City time, on the relevant refunding date, request each
Lender to make, and each Lender hereby agrees to make, a Loan to such Borrower,
at the rate applicable to the Swing Line Loans of such Borrower in an amount
equal to such Lender's Commitment Percentage of the amount of such Swing Line
Loans of such Borrower (the "Refunded Swing


                                      -21-
<PAGE>   26
Line Loans") outstanding on the date of such notice, to repay the Swing Line
Lender. Each Lender shall make the amount of such Loan available to the
Operations Agent at its office set forth in Section 9.2 in immediately available
funds, no later than 3:00 P.M., New York City time, on the date of such notice.
The proceeds of such Loans shall be distributed by the Operations Agent to the
Swing Line Lender and immediately applied by the Swing Line Lender to repay the
Refunded Swing Line Loans. Effective on the day such Loans are made, the portion
of the Swing Line Loans so paid shall no longer be outstanding as Swing Line
Loans.

                  (b) The making of any Swing Line Loan hereunder at the request
of a Borrower shall be subject to the satisfaction of the applicable conditions
precedent thereto set forth in Section 4.2 (unless otherwise waived in
accordance with Section 9.1) and with respect to the determination under Section
4.2(c) as to whether a Default or Event of Default shall have occurred with
respect to the requesting Borrower on the date of a request, the Swing Line
Lender shall be entitled to rely on, and shall not be obligated to make a Swing
Line Loan if it has received, a notice of the occurrence of any Default or Event
of Default with respect to the requesting Borrower.

                  (c) If prior to the making of a Loan to a Borrower pursuant to
Section 2.18(a) one of the events described in paragraph (e) of Section 7 shall
have occurred with respect to such Borrower, each Lender severally,
unconditionally and irrevocably agrees that it shall purchase a participating
interest in the applicable Swing Line Loans ("Unrefunded Swing Line Loans") in
an amount equal to the amount of Loans which would otherwise have been made by
such Lender pursuant to Section 2.18(a). Each Lender will immediately transfer
to the Operations Agent, in immediately available funds, the amount of its
participation (the "Swing Line Participation Amount") and the proceeds of such
participation shall be distributed by the Operations Agent to the Swing Line
Lender in such amount as will reduce the amount of the participating interest
retained by the Swing Line Lender in its Swing Line Loans to the amount of the
Loans which were to have been made by it pursuant to Section 2.18(a).

                  (d) Whenever, at any time after the Swing Line Lender has
received from any Lender such Lender's Swing Line Participation Amount, the
Swing Line Lender receives any payment on account of the Swing Line Loans, the
Swing Line Lender will distribute to such Lender its Swing Line Participation
Amount (appropriately adjusted, in the case of interest payments, to reflect the
period of time during which such Lender's participating interest was outstanding
and funded and, in the case of principal and interest payments, to reflect such
Lender's pro rata portion of such payment if such payment is not sufficient to
pay the principal of and interest on all Swing Line Loans then due); provided,
however, that in the event that such payment received by the Swing Line Lender
is required to be returned, such Lender will return to the Swing Line Lender any
portion thereof previously distributed to it by the Swing Line Lender.


                                      -22-
<PAGE>   27
                  (e) Each Lender's obligation to make the Loans referred to in
Section 2.18(a) and to purchase participating interests pursuant to Section
2.18(c) shall, subject to clause (ii) below, be absolute, irrevocable and
unconditional and shall not be affected by any circumstance, including, without
limitation, (i) any setoff; counterclaim, recoupment, defense or other right
which such Lender may have against the Swing Line Lender or any other Person for
any reason whatsoever; (ii) the occurrence or continuance of a Default or an
Event of Default (unless the Swing Line Lender shall have received notice of the
occurrence of a Default or Event of Default with respect to the requesting
Borrower that has not been waived or cured prior to the making of any Swing Line
Loan hereunder) or the failure to satisfy any of the other conditions specified
in Section 4; (iii) any adverse change in the condition (financial or otherwise)
of any Borrower; (iv) any breach of this Agreement or any other Loan Document by
any Borrower or any Lender; or (v) any other circumstance, happening or event
whatsoever, whether or not similar to any of the foregoing.

                    SECTION 3. REPRESENTATIONS AND WARRANTIES

                  To induce the Agents and the Lenders to enter into this
Agreement and to make the Loans, each Fund, on behalf of itself and on behalf of
each investment portfolio thereof which is a Borrower, represents and warrants
to the Agents and each Lender that on the date of this Agreement or on the date
of any borrowing, as applicable, (it being agreed that each Fund represents and
warrants only to matters with respect to itself and each investment portfolio
thereof which is a Borrower):

                  3.1 Financial Condition. The statement of assets and
liabilities as of the Borrower's most recently ended fiscal year for which
annual reports have been prepared and the related statements of operations and
of changes in net assets for the fiscal year ended on such date, copies of which
financial statements, certified by the independent public accountants for such
Borrower, have heretofore been delivered to each Lender, fairly present, in all
material respects, the financial position of such Borrower as of such date and
the results of its operations for such period, in conformity with GAAP.

                  3.2 No Change. Since the date of the statement of assets and
liabilities for the most recently ended fiscal year for which annual reports
have been prepared for the Borrower, there has been no development or event
which has had or could reasonably be expected to have a Material Adverse Effect
with respect to such Borrower.

                  3.3 Existence: Compliance with Law. Such Fund (a) is duly
organized, validly existing and in good standing under the laws of the
jurisdiction of its organization, (b) has the corporate power and authority as
to AIM Equity Funds, AIM International Funds, AIM Tax-Exempt, AIM Advisor Funds,
AIM Variable Insurance, AIM Summit Fund and AIM Floating Rate, and trust power
and authority as to AIM Funds Group, AIM Investment Securities, AIM Growth
Series, AIM Series Trust, AIM Investment Funds, GT Global Series and GT Global
Trust, and the legal right, to own its property and to conduct the business in


                                      -23-
<PAGE>   28
which it is currently engaged, (c) is duly qualified and in good standing under
the laws of each jurisdiction where its ownership of property or the conduct of
its business requires such qualification and (d) is in compliance with all
Requirements of Law except to the extent that the failure to comply therewith
could not, in the aggregate, reasonably be expected to have a Material Adverse
Effect. The shares of such Fund representing an interest in each Borrower have
been validly authorized and are duly registered for sale under the federal
securities laws.

                  3.4 Power: Authorization: Enforceable Obligations. Such Fund
has the corporate power and authority as to AIM Equity Funds, AIM International
Funds, AIM Tax-Exempt, AIM Advisor Funds, AIM Variable Insurance, AIM Summit
Fund and AIM Floating Rate, and trust power and authority as to AIM Funds Group,
AIM Investment Securities, AIM Growth Series, AIM Series Trust, AIM Investment
Funds, GT Global Series and GT Global Trust, and the legal right, to make,
deliver and perform the Loan Documents to which it is a party and to borrow
hereunder on its own behalf (as to AIM Summit Fund and AIM Floating Rate) or on
behalf of each investment portfolio thereof which is a Borrower and has taken
all necessary corporate or trust action to authorize the borrowings on the terms
and conditions of this Agreement and any Notes and to authorize the execution,
delivery and performance of the Loan Documents to which it is a party. No
consent or authorization of, filing with, notice to or other act by or in
respect of; any Governmental Authority or any other Person is required in
connection with the borrowings hereunder or with the execution, delivery,
performance, validity or enforceability of the Loan Documents to which such Fund
and any investment portfolio thereof which is a Borrower is a party. This
Agreement and each other Loan Document to which such Fund is a party will be
duly executed and delivered by such Fund on its own behalf or on behalf of each
investment portfolio thereof which is a Borrower. This Agreement constitutes,
and each other Loan Document to which such Fund is a party when executed and
delivered will constitute, a legal, valid and binding obligation of such Fund
and each investment portfolio thereof which is a Borrower enforceable against
such Fund and each investment portfolio thereof which is a Borrower in
accordance with its terms, except as enforceability may be limited by applicable
bankruptcy, insolvency, reorganization, moratorium or similar laws affecting the
enforcement of creditors' rights generally and by general equitable principles
(whether enforcement is sought by proceedings in equity or at law).

                  3.5 No Legal Bar. The execution, delivery and performance of
the Loan Documents to which such Fund and each investment portfolio thereof
which is a Borrower is a party, the borrowings hereunder and the use of the
proceeds thereof will not violate any Requirement of Law (including, without
limitation, the 1940 Act) or Contractual Obligation of such Fund or any
investment portfolio thereof which is a Borrower either of which could have a
Material Adverse Effect and will not result in, or require, the creation or
imposition of any Lien on any of their respective properties or revenues
pursuant to any such Requirement of Law or Contractual Obligation which could
have a Material Adverse Effect.

                  3.6 No Material Litigation. No litigation, investigation or
proceeding of or before any arbitrator or Governmental Authority is pending or,
to the knowledge of such Fund or any investment portfolio thereof which is a
Borrower, threatened by or against such Fund or any


                                      -24-
<PAGE>   29
investment portfolio thereof which is a Borrower or against any of their
respective properties or revenues (a) with respect to any of the Loan Documents
or any of the transactions contemplated hereby or thereby, or (b) which could
reasonably be expected to have a Material Adverse Effect.

                  3.7 No Default. Neither such Fund nor any investment portfolio
thereof which is a Borrower is in default under or with respect to any of its
Contractual Obligations in any respect which default could reasonably be
expected to have a Material Adverse Effect. No Default or Event of Default has
occurred and is continuing.

                  3.8 Ownership of Property. Neither such Fund nor any
investment portfolio which is a Borrower owns any real property.

                  3.9 No Burdensome Restrictions. No Requirement of Law or
Contractual Obligation of such Fund or any investment portfolio thereof which is
a Borrower could reasonably be expected to have a Material Adverse Effect.

                  3.10 Taxes. (a) Each Borrower has filed all tax returns which,
to the knowledge of such Fund and such Borrower, are required to be filed and
has paid all taxes shown to be due and payable on said returns or on any
assessments made against it or any of its property and all other taxes, fees or
other charges imposed on it or any of its property by any Governmental Authority
(other than any the amount or validity of which are currently being contested in
good faith by appropriate proceedings and with respect to which reserves in
conformity with GAAP have been provided on the books of such Fund or such
Borrower); no tax Lien has been filed, and, to the knowledge of such Fund and
each investment portfolio thereof which is a Borrower, no claim is being
asserted, with respect to any such tax, fee or other charge.

                  (b) Each Borrower is a "regulated investment company" as
defined in the Code.

                  3.11 Federal Regulations. If greater than 25% of the Total
Assets of a Borrower consists of "margin stock" (as defined in Regulation U),
the aggregate principal amount of the Loans will not exceed the sum of (i) 50%
of the aggregate market value (determined in accordance with Regulation U) of
"margin stock" owned by such Borrower plus (ii) the good faith loan value
(determined in accordance with Regulation U) of non-margin stock and all other
collateral (except puts, calls or combinations thereof) owned by such Borrower.
If requested by any Lender or the Administrative Agent from time to time, such
Fund on its own behalf (with respect to AIM Summit Fund and AIM Floating Rate)
or on behalf of each investment portfolio thereof which is a Borrower will
furnish to the Administrative Agent and each Lender a statement to the foregoing
effect in conformity with the requirements of Form FR G-3 (if applicable) or
Form FR U-1 referred to in Regulation U, as the case may be.

satisfy at or before maturity or before they become delinquent, as the case may
be, all its obligations of whatever nature (including taxes), except where (i)
the amount or validity thereof is currently being contested in good faith by
appropriate proceedings and reserves in conformity with GAAP with respect
thereto have been provided on the books of such Borrower, as the case may be or
(ii) the lack of timely payment thereof would not reasonably be expected to have
a Material Adverse Effect.

normal conduct of its business, except to the extent that failure to take such
actions could not reasonably be expected to have a Material Adverse Effect;
comply with all Contractual Obligations and Requirements of Law except to the
extent that failure to comply therewith could not, in the aggregate, be

useful and necessary in its business, if any, in good working order and
condition; maintain with financially sound and reputable insurance companies

engaged in the same or a similar business or as may otherwise be required by the
Securities and Exchange Commission or any successor Governmental Authority
(including, without limitation, (a) fidelity bond coverage as shall be required
by Rule 17g-1 promulgated under the 1940 Act or any successor provision and (b)

request, full information as to the insurance carried.

in conformity with GAAP and all Requirements of Law shall be made of all
dealings and transactions in relation to its business and activities; and permit
representatives of any Lender, at such Lender's expense, to visit and inspect
any of its properties and examine and make abstracts from any of its books and
records relating to the Borrowers, portfolio holdings or financial condition at
any reasonable time and as often as may reasonably be desired and to discuss the

Borrower with officers and employees of such Borrower and with its independent
certified public accountants.

         either case (i) or (ii) , if not cured or if adversely determined, as
         the case may be, could reasonably be expected to have a Material
         Adverse Effect;

                  (c) any litigation or proceeding affecting such Borrower in
         which the amount involved is $1,000,000 (or its equivalent in any other

         any other event shall occur or condition exist, the effect of which
         default or other event or condition is to cause, or to permit the
         holder or holders of such Indebtedness or beneficiary or

         such Borrower incurs any liability to any Plan which could reasonably
         be expected to have a Material Adverse Effect; or

                              SECTION 8. THE AGENTS

                  8.1 Appointment. Each Lender hereby irrevocably designates and
appoints each Agent as the agent of such Lender under this Agreement and the
other Loan Documents, and each such Lender irrevocably authorizes such Agent, in
such capacity, to take such action on its behalf under the provisions of this
Agreement and the other Loan Documents and to exercise such powers and perform
such duties as are expressly delegated to such Agent by the terms of this
Agreement and the other Loan Documents, together with such other powers as are
reasonably incidental thereto. Notwithstanding any provision to the contrary
elsewhere in this Agreement, the Agents shall not have any duties or
responsibilities, except those expressly set forth herein, or any fiduciary
relationship with any Lender, and no implied covenants, functions,
responsibilities, duties, obligations or liabilities shall be read into this
Agreement or any other Loan Document or otherwise exist against the Agents.

                  8.2 Delegation of Duties. Each Agent may execute any of its
duties under this Agreement and the other Loan Documents by or through agents or
attorneys-in-fact and shall be entitled to advice of counsel concerning all
matters pertaining to such duties.


                                      -39-
<PAGE>   44
                  8.3 Exculpatory Provisions. Neither of the Agents nor any of
their respective officers, directors, employees, agents, attorneys-in-fact or
Affiliates shall be (a) liable for any action lawfully taken or omitted to be
taken by it or such Person under or in connection with this Agreement or any
other Loan Document (except for its or such Person's own gross negligence, bad
faith or willful misconduct) or (b) responsible in any manner to any of the
Lenders for any recitals, statements, representations or warranties made by any
Fund or any Borrower or any officer of any Fund contained in this Agreement or
any other Loan Document or in any certificate, report, statement or other
document referred to or provided for in, or received by the Agents under or in
connection with, this Agreement or any other Loan Document or for the value,
validity, effectiveness, genuineness, enforceability or sufficiency of this
Agreement or any other Loan Document or for any failure of any Borrower to
perform its obligations hereunder or thereunder. The Agents shall not be under
any obligation to any Lender to ascertain or to inquire as to the observance or
performance of any of the agreements contained in, or condition of; this
Agreement or any other Loan Document, or to inspect the properties, books or
records of any Fund or any Borrower;

                  8.4 Reliance by Agents. The Agents shall be entitled to rely,
and shall be fully protected in relying, upon any Note, writing, resolution,
notice, consent, certificate, affidavit, letter, telecopy, telex or teletype
message, statement, order or other document or conversation reasonably believed
by it to be genuine and correct and to have been signed, sent or made by the
proper Person or Persons and upon advice and statements of legal counsel
(including, without limitation, counsel to the Funds or the Borrowers),
independent accountants and other experts selected by either of the Agents. The
Agents may deem and treat the payee of any Note as the owner thereof for all
purposes unless a written notice of assignment; negotiation or transfer thereof
shall have been filed with the Agents. The Agents shall be fully justified in
failing or refusing to take any action under this Agreement or any other Loan
Document unless it shall first receive such advice or concurrence of the
Required Lenders as it deems appropriate or it shall first be indemnified to its
satisfaction by the Lenders against any and all liability and expense which may
be incurred by it by reason of taking or continuing to take any such action. The
Agents shall in all cases be fully protected in acting, or in refraining from
acting, under this Agreement and the other Loan Documents in accordance with a
request of the Required Lenders, and such request and any action taken or
failure to act pursuant thereto shall be binding upon all the Lenders and all
future holders of the Loans.

                  8.5 Notice of Default. Neither the Administrative Agent, the
Operations Agent nor the Swing Line Lender shall be deemed to have knowledge or
notice of the occurrence of any Default or Event of Default hereunder unless the
Administrative Agent, the Operations Agent or the Swing Line Lender, as
applicable, has received notice from a Lender or a Borrower referring to this
Agreement, describing such Default or Event of Default and stating that such
notice is a "notice of default." In the event that the Administrative Agent
receives such a notice, the Administrative Agent shall give notice thereof to
the Lenders. The Administrative Agent shall take such action with respect to
such Default or Event of Default as shall be reasonably directed by the Required
Lenders; provided, that unless and until the Administrative Agent shall have
received such directions, the Administrative Agent may (but


                                      -40-
<PAGE>   45
shall not be obligated to) take such action, or refrain from taking such action,
with respect to such Default or Event of Default as it shall deem advisable in
the best interests of the Lenders.

                  8.6 Non-Reliance on Agents and Other Lenders. Each Lender
expressly acknowledges that neither of the Agents nor any of their respective
officers, directors, employees, agents, attorneys-in-fact or Affiliates has made
any representations or warranties to it and that no act by either Agent
hereinafter taken, including any review of the affairs of the Funds or
Borrowers, shall be deemed to constitute any representation or warranty by the
Agents to any Lender. Each Lender represents to each Agent that it has,
independently and without reliance upon either of the Agents or any other
Lender, and based on such documents and information as it has deemed
appropriate, made its own appraisal of and investigation into the business,
operations, property, financial and other condition and creditworthiness of the
Borrowers and made its own decision to make its Loans hereunder and enter into
this Agreement. Each Lender also represents that it will, independently and
without reliance upon either of the Agents or any other Lender, and based on
such documents and information as it shall deem appropriate at the time,
continue to make its own credit analysis, appraisals and decisions in taking or
not taking action under this Agreement and the other Loan Documents, and to make
such investigation as it deems necessary to inform itself as to the business,
operations, property, financial and other condition and creditworthiness of the
Borrowers. Except for notices, reports and other documents expressly required to
be furnished to the Lenders by the respective Agents hereunder, the Agents shall
not have any duty or responsibility to provide any Lender with any credit or
other information concerning the business, operations, property, condition
(financial or otherwise), prospects or creditworthiness of the Funds or the
Borrowers which may come into the possession of the Agents or any of their
respective officers, directors, employees, agents, attorneys-in-fact or
Affiliates.

                  8.7 Indemnification. The Lenders agree to indemnify each of
the Agents in its respective capacity as such (to the extent not reimbursed by
the Borrowers and without limiting the obligation of the Borrowers to do so),
ratably according to their respective Commitment Percentages in effect on the
date on which indemnification is sought (or, if indemnification is sought after
the date upon which the Commitments shall have terminated and the Loans shall
have been paid in full, ratably in accordance with their Commitment Percentages
immediately prior to such date), from and against any and all liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements of any kind whatsoever which may at any time
(including, without limitation, at any time following the payment of the Loans)
be imposed on, incurred by or asserted against such Agent in any way relating to
or arising out of; the Commitments, this Agreement, any of the other Loan
Documents or any documents contemplated by or referred to herein or therein or
the transactions contemplated hereby or thereby or any action taken or omitted
by such Agent under or in connection with any of the foregoing; provided that no
Lender shall be liable for the payment of any portion of such liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements resulting solely from such Agent's gross negligence,
bad faith or willful misconduct. The agreements in this subsection shall survive
the payment of the Loans and all other amounts, payable hereunder.


                                      -41-
<PAGE>   46
                  8.8 Agent in Its Individual Capacity. The Agents and their
respective Affiliates may make loans to, accept deposits from and generally
engage in any kind of business with any Fund or any Borrower as though the
Agents were not the Administrative Agent and the Operations Agent hereunder and
under the other Loan Documents. With respect to the Loans made by it, each of
the Agents shall have the same rights and powers under this Agreement and the
other Loan Documents as any Lender and may exercise the same as though it were
not the Agent, and the terms "Lender" and "Lenders" shall include the Agents in
their individual capacities.

                  8.9 Successor Agent. The Administrative Agent or the
Operations Agent may resign as Administrative Agent or Operations Agent upon 10
days' notice to the Lenders. If the Administrative Agent or the Operations Agent
shall resign as Administrative Agent or Operations Agent under this Agreement
and the other Loan Documents, then the Required Lenders shall appoint from among
the Lenders a successor agent for the Lenders, which successor agent shall be
approved by the Borrowers, whereupon such successor agent shall succeed to the
rights, powers and duties of the Agent, and the term "Administrative Agent" or
"Operations Agent", as applicable, shall mean such successor agent effective
upon such appointment and approval, and the former Agent's rights, powers and
duties as Agent shall be terminated, without any other or further act or deed on
the part of such former Agent or any of the parties to this Agreement or any
holders of the Loans. After any retiring Agent's resignation as Agent, the
provisions of this Section 8 shall inure to its benefit as to any actions taken
or omitted to be taken by it while it was Agent under this Agreement and the
other Loan Documents.


                            SECTION 9. MISCELLANEOUS

Required Lenders, the Administrative Agent may, from time to time, (a) enter
into with a Fund on its own behalf or on behalf of an investment portfolio
thereof which is a Borrower written amendments, supplements or modifications
hereto and to the other Loan Documents for the purpose of adding any provisions
to this Agreement or the other Loan Documents or changing in any manner the
rights of the Lenders or of such Borrowers hereunder or thereunder or (b) waive,
on such terms and conditions as the Required Lenders or the Administrative
Agent, as the case may be, may specify in such instrument, any of the
requirements of this Agreement or the other Loan Documents or any Default or
Event of Default and its consequences; provided, however, that no such waiver

subsection or reduce the percentage specified in the definition of Required
Lenders, or consent to the assignment or transfer by any Fund on its own behalf
or on behalf of any investment portfolio thereof which is a Borrower of any of
its rights and obligations under this Agreement and the other Loan Documents, in
each case without the written consent of all the Lenders, or (iii) amend, modify
or waive any provision of Section 8 without the written consent of the then

purpose for which given.

                  9.3 No Waiver: Cumulative Remedies. No failure to exercise and
no delay in exercising, on the part of either Agent or any Lender, any right,
remedy, power or privilege hereunder or under the other Loan Documents shall

exercise thereof or the exercise of any other right, remedy, power or privilege.
The rights, remedies, powers and privileges herein provided are cumulative and
not exclusive of any rights, remedies, powers and privileges provided by law.

                  9.4 Survival of Representations and Warranties. All

severally, with respect to its pro rata portions as allocated by AIM in its
reasonable discretion (a) to pay or reimburse the Administrative Agent for its
reasonable out-of-pocket costs and expenses incurred in connection with the
development, preparation and execution of; and any amendment, supplement or
modification to, this Agreement and the other Loan Documents and any other
documents prepared in connection herewith or therewith, and the consummation and
administration of the transactions contemplated hereby and thereby, including,
without limitation, the reasonable fees and disbursements of counsel to the
Administrative Agent, (b) to pay or reimburse each Lender and either Agent for
all its reasonable out-of-pocket costs and expenses incurred in connection with
the enforcement or preservation of any rights under this Agreement with respect
to such Borrower, the other Loan Documents and any such other documents,
including, without limitation, the reasonable fees and disbursements of counsel
to each Lender and of counsel to the Administrative Agent, (c) to pay,
indemnify, and hold each Lender and the Agents harmless from, any and all
recording and filing fees and any and all liabilities with respect to, or
resulting from any delay in paying, stamp, excise and other taxes, if any, which
may be payable or determined to be payable in connection with the execution and
delivery of; or consummation or administration of any of the transactions
contemplated by, or any amendment, supplement or modification of; or any waiver
or consent under or in respect of; this Agreement, the other Loan Documents and
any such other documents with respect to such Borrower, and (d) to pay,
indemnify, and hold each Lender and the Agents harmless from and


                                      -44-
<PAGE>   49
against any and all other liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses or disbursements of any kind or
nature whatsoever arising from the execution, delivery, enforcement, performance
and administration of this Agreement, the other Loan Documents and any such
other documents (all the foregoing in this clause (d), collectively, the
"indemnified liabilities"), provided; that such Borrower shall have no
obligation hereunder to the Agents or any Lender with respect to indemnified
liabilities arising from (i) the gross negligence, bad faith or willful
misconduct of either of the Agents or any such Lender or (ii) legal proceedings
commenced against either of the Agents or any such Lender by any security holder
or creditor of a Borrower arising out of and based upon rights afforded any such
security holder or creditor solely in its capacity as such. The agreements in
this subsection shall survive repayment of the Loans and all other amounts
payable hereunder.

                  9.6 Successors and Assigns: Participations and Assignments.
(a) This Agreement shall be binding upon and inure to the benefit of each Fund,
the Borrowers, the Lenders, the Agents and their respective successors and
assigns, except that no Fund or any Borrower may assign or transfer any of its
rights or obligations under this Agreement without the prior written consent of
each Lender.

                  (b) Any Lender may, in the ordinary course of its business and
in accordance with applicable law, at any time sell to one or more banks
("Participants") participating interests in any Loan owing to such Lender, any
Commitment of such Lender or any other interest of such Lender hereunder and
under the other Loan Documents. In the event of any such sale by a Lender of a
participating interest to a Participant, such Lender's obligations under this
Agreement to the other parties to this Agreement shall remain unchanged, such
Lender shall remain solely responsible for the performance thereof; such Lender
shall remain the holder of any such Loan for all purposes under this Agreement
and the other Loan Documents, and the Borrowers and the Agents shall continue to
deal solely and directly with such Lender in connection with such Lender's
rights and obligations under this Agreement and the other Loan Documents. Any
agreement pursuant to which any Lender may grant such a participating interest
shall provide that such Lender shall retain the sole right and responsibility to
enforce the obligations of the Borrowers hereunder including the right to
approve any amendment, modification or waiver of any provision of this
Agreement; provided that such participation agreement may provide that such
Lender will not agree to any modification, amendment or waiver of this Agreement
described in clauses (i) of the proviso in Section 9.1 without the consent of
the Participant. Each Borrower agrees that if amounts outstanding under this
Agreement are due or unpaid, or shall have been declared or shall have become
due and payable upon the occurrence of an Event of Default, each Participant
shall, to the maximum extent permitted by applicable law, be deemed to have the
right of setoff in respect of its participating interest in amounts owing under
this Agreement to the same extent as if the amount of its participating interest
were owing directly to it as a Lender under this Agreement, provided that, in
purchasing such participating interest, such Participant shall be deemed to have
agreed to share with the Lenders the proceeds thereof as provided in subsection
9.7(a) as fully as if it were a Lender hereunder. Each Borrower also agrees that
each Participant shall be entitled to the benefits of subsections 2.12, 2.13 and
2.14 with respect to its participation in the


                                      -45-
<PAGE>   50
Commitments and the Loans outstanding from time to time as if it was a Lender;
provided that, in the case of subsections 2.12 and 2.13, such Participant shall
have complied with the requirements of said subsection and provided, further,
that no Participant shall be entitled to receive any greater amount pursuant to
any such subsection than the transferor Lender would have been entitled to
receive in respect of the amount of the participation transferred by such
transferor Lender to such Participant had no such transfer occurred.

                  (c) Any Lender may, in the ordinary course of its business and
in accordance with applicable law, at any time and from time to time assign to
any Lender or any affiliate thereof (but only if such affiliate, together with
its Affiliates, does not own of record 5% or more of the outstanding voting
securities of a Borrower and only if such affiliate is a "bank" (as such term is
defined in Section 2(a)(5) of the 1940 Act)) or, with the consent of each Fund,
the Administrative Agent and the Operations Agent (which in each case shall not
be unreasonably withheld), to a "bank" (as such term is defined in Section
2(a)(5) of the 1940 Act) (an "Assignee") all or any part of its rights and
obligations under this Agreement and the other Loan Documents pursuant to an
Assignment and Acceptance, substantially in the form of Exhibit B, executed by
such Assignee, such assigning Lender (and, in the case of an Assignee that is
not then a Lender or an affiliate thereof; by each Fund and the Administrative
Agent) and delivered to the Administrative Agent for its acceptance and (upon
the Administrative Agent's notice thereof to the Operations Agent) recording in
the Register by the Operations Agent; provided, however, that assignments to
banks other than Lenders or affiliates thereof must be in amounts of at least
$30,000,000 or, if less, the entire amount of the assignor's rights and
obligations. Upon such execution, delivery, acceptance and recording, from and
after the effective date determined pursuant to such Assignment and Acceptance,
(x) the Assignee thereunder shall be a party hereto and, to the extent provided
in such Assignment and Acceptance, have the rights and obligations of a Lender
hereunder with a Commitment as set forth therein, and (y) the assigning Lender
thereunder shall, to the extent provided in such Assignment and Acceptance, be
released from its obligations under this Agreement (and, in the case of an
Assignment and Acceptance covering all or the remaining portion of an assigning
Lender's rights and obligations under this Agreement, such assigning Lender
shall cease to be a party hereto). Notwithstanding any provision of this
paragraph (c) and paragraph (e) of this subsection, the consent of the Funds
shall not be required, and, unless requested by the Assignee and/or the
assigning Lender, new Notes shall not be required to be executed and delivered
on behalf of the Borrowers, for any assignment which occurs at any time when any
of the events described in Section 7(e) shall have occurred and be continuing.

                  (d) The Operations Agent, on behalf of the Borrowers, shall
maintain at the address of the Operations Agent referred to in subsection 9.2 a
copy of each Assignment and Acceptance delivered to it and a register (the
"Register") for the recordation of the names and addresses of the Lenders and
the Commitment of; and principal amount of the Loans owing to, each Lender from
time to time. The entries in the Register shall be conclusive, in the absence of
manifest error, and the Borrowers, the Agents and the Lenders may (and, in the
case of any Loan or other obligation hereunder not evidenced by a Note, shall)
treat each Person whose name is recorded in the Register as the owner of a Loan
or other obligation hereunder as the owner


                                      -46-
<PAGE>   51
thereof for all purposes of this Agreement and the other Loan Documents,
notwithstanding any notice to the contrary. Any assignment of any Loan or other
obligation hereunder not evidenced by a Note shall be effective only upon
appropriate entries with respect thereto being made in the Register. The
Register shall be available for inspection by the Borrowers or any Lender at any
reasonable time and from time to time upon reasonable prior notice.

                  (e) Upon its receipt of an Assignment and Acceptance executed
by an assigning Lender and an Assignee (and, in the case of an Assignee that is
not then a Lender or an affiliate thereof; by each Fund, the Administrative
Agent and the Operations Agent) and together with, in the case of an Assignee
that is not then a Lender or an affiliate thereof; payment by the assigning
Lender or Assignee to the Administrative Agent of a registration and processing
fee of $3,000, the Administrative Agent shall (i) promptly accept such
Assignment and Acceptance and provide notice thereof to the Operations Agent and
(ii) on the effective date determined pursuant thereto request the Operations
Agent to record the information contained therein in the Register and give
notice of such acceptance and recordation to the Lenders, the Funds and the
Borrowers.

                  (f) Each Fund and each Borrower authorizes each Lender to
disclose to any Participant or Assignee (each, a "Transferee") and any
prospective Transferee, subject to the provisions of subsection 9.16, any and
all financial information in such Lender's possession concerning the Funds or
any Borrower and their Affiliates which has been delivered to such Lender by or
on behalf of the Funds or the Borrowers pursuant to this Agreement or which has
been delivered to such Lender by or on behalf of the Funds or the Borrowers in
connection with such Lender's credit evaluation of the Borrowers and their
Affiliates prior to becoming a party to this Agreement.

                  (g) For avoidance of doubt, the parties to this Agreement
acknowledge that the provisions of this subsection concerning assignments of
Loans and Notes relate only to absolute assignments and that such provisions do
not prohibit assignments creating security interests, including, without
limitation, any pledge or assignment by a Lender of any Loan or Note to any
Federal Reserve Bank in accordance with applicable law.

                  9.7 Adjustments: Set-off. (a) If any Lender (a "Benefitted
Lender") shall at any time receive any payment of all or part of its Loans
(other than a Swing Line Loan), or interest thereon, or receive any collateral
in respect thereof (whether voluntarily or involuntarily, by set-off; pursuant
to events or proceedings of the nature referred to in Section 7(e), or
otherwise), in a greater proportion than any such payment to or collateral
received by any other Lender, if any, in respect of such other Lender's Loans,
or interest thereon, such Benefitted Lender shall purchase for cash from the
other Lenders a participating interest in such portion of each such other
Lender's Loan, or shall provide such other Lenders with the benefits of any such
collateral, or the proceeds thereof; as shall be necessary to cause such
Benefitted Lender to share the excess payment or benefits of such collateral or
proceeds ratably with each of the Lenders; provided, however, that if all or any
portion of such excess payment or benefits is thereafter


                                      -47-
<PAGE>   52
recovered from such Benefitted Lender, such purchase shall be rescinded, and the
purchase price and benefits returned, to the extent of such recovery, but
without interest.

                  (b) In addition to any rights and remedies of the Lenders
provided by law, each Lender shall have the right, without prior notice to any
Borrower, any such notice being expressly waived by each Borrower to the extent
permitted by applicable law, upon any amount becoming due and payable by a
Borrower hereunder (whether at the stated maturity, by acceleration or
otherwise) to set-off and appropriate and apply against such amount any and all
deposits (general or special, time or demand, provisional or final), in any
currency, and any other credits, indebtedness or claims, in any currency, in
each case whether direct or indirect, absolute or contingent, matured or
unmatured, at any time held or owing by such Lender or any branch or agency
thereof to or for the credit or the account of such Borrower. Each Lender agrees
promptly to notify such Borrower and the Agents after any such set-off and
application made by such Lender, provided that the failure to give such notice
shall not affect the validity of such set-off and application. Nothing herein
shall permit any set-off against any other Borrower of obligations of a
different Borrower.

                  9.8 Counterparts. This Agreement may be executed by one or
more of the parties to this Agreement on any number of separate counterparts
(including by facsimile transmission), and all of said counterparts taken
together shall be deemed to constitute one and the same instrument. A set of the
copies of this Agreement signed by all the parties shall be lodged with each
Fund and the Administrative Agent.

                  9.9 Severability. 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; and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

                  9.10 Integration. This Agreement and the other Loan Documents
represent the agreement of each Fund, each Borrower, the Agents and the Lenders
with respect to the subject matter hereof; and there are no promises,
undertakings, representations or warranties by the Agents or any Lender relative
to the subject matter hereof not expressly set forth or referred to herein or in
the other Loan Documents.

                  9.11 GOVERNING LAW. THIS AGREEMENT AND THE RIGHTS AND
OBLIGATIONS OF THE PARTIES HEREUNDER SHALL BE GOVERNED BY, AND CONSTRUED AND
INTERPRETED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

                  9.12 Submission To Jurisdiction: Waivers. Each Fund and each
Borrower hereby irrevocably and unconditionally:


                                      -48-

         of the Courts of the State of New York, the courts of the United States
         of America for the Southern District of New York, and appellate courts
         from any thereof;

                  (b) consents that any such action or proceeding may be brought
         in such courts and waives any objection that it may now or hereafter
         have to the venue of any such action or proceeding in any such court or
         that such action or proceeding was brought in an inconvenient court and
         agrees not to plead or claim the same;

                  (c) agrees that service of process in any such action or
         proceeding may be effected by mailing a copy thereof by registered or
         certified mail (or any substantially similar form of mail), postage
         prepaid, to such Fund or such Borrower at its address set forth in
         subsection 9.2 or at such other address of which the Administrative
         Agent shall have been notified pursuant thereto;

                  (d) agrees that nothing herein shall affect the right to
         effect service of process in any other manner permitted by law or shall
         limit the right to sue in any other jurisdiction; and

                  (e) waives, to the maximum extent not prohibited by law, any
         right it may have to claim or recover in any legal action or proceeding
         referred to in this subsection any special, exemplary, punitive or
         consequential damages.

obligation pursuant to subsection 2.13(b) of the Credit Agreement.

Agreement on behalf of itself, and, with respect to all Funds other than AIM
Summit Fund and AIM Floating Rate, certain of its respective investment
portfolios set forth beneath such Fund's name on Schedule I attached to the
Credit Agreement, the Lenders named therein, State Street Bank and Trust
Company, as Operations Agent (in such capacity, the "Operations Agent"), and The
Chase Manhattan Bank, as Administrative Agent for the Lenders (in such capacity,
the "Administrative Agent"). Unless otherwise defined herein, terms defined in
the Credit Agreement and used herein shall have the meanings given to them in
the Credit Agreement.

                  Societe Generale, New York Branch (the "Assignor") and
Citibank, N.A. (the "Assignee") agree as follows:

                  1. The Assignor hereby irrevocably sells and assigns to the
Assignee without recourse to the Assignor, and the Assignee hereby irrevocably
purchases and assumes from the Assignor without recourse to the Assignor, as of
the Effective Date (as defined in Schedule 1 hereto), the interest described in
Schedule 1 hereto (the "Assigned Interest") in and to the Assignor's rights and
obligations under the Credit Agreement.

                  2. The Assignor (a) makes no representation or warranty and
assumes no responsibility with respect to any statements, warranties or
representations made in or in connection with the Credit Agreement or with
respect to the execution, legality, validity, enforceability, genuineness,
sufficiency or value of the Credit Agreement, any other Loan Document or any
other instrument or

<PAGE>   32



document furnished pursuant thereto, other than that the Assignor has not
created any adverse claim upon the interest being assigned by it hereunder and
that such interest is free and clear of any such adverse claim; (b) makes no
representation or warranty and assumes no responsibility with respect to the
financial condition of any Borrower, or any other obligor or the performance or
observance by any Borrower or any other obligor of any of their respective
obligations under the Credit Agreement or any other Loan Document or any other
instrument or document furnished pursuant hereto or thereto; and (c) attaches
any Notes held by it evidencing the Assigned Facility and (i) requests that the
Administrative Agent, upon request by the Assignee, exchange the attached Notes
for a new Note or Notes payable to the Assignee and (ii) if the Assignor has
retained any interest in the Assigned Facility, requests that the Administrative
Agent exchange the attached Notes for a new Note or Notes payable to the
Assignor, in each case in amounts which reflect the assignment being made hereby
(and after giving effect to any other assignments which have become effective on
the Effective Date).

                  3. The Assignee (a) represents and warrants that it is legally
authorized to enter into this Assignment and Acceptance, that it is a "bank" (as
defined in Section 2(a)(5) of the 1940 Act) and to its best knowledge, it is not
an "Affiliated person" (as defined in Section 2(a)(3) of the 1940 Act) of any
Borrower or AIM; (b) confirms that it has received a copy of the Credit
Agreement, together with copies of such other documents and information as it
has deemed appropriate to make its own credit analysis and decision to enter
into this Assignment and Acceptance; (c) agrees that it will, independently and
without reliance upon the Assignor, the Administrative Agent, the Operations
Agent or any other Lender and based on such documents and information as it
shall deem appropriate at the time, continue to make its own credit decisions in
taking or not taking action under the Credit Agreement, the other Loan Documents
or any other instrument or document furnished pursuant hereto or thereto; (d)
appoints and authorizes the Administrative Agent and the Operations Agent to
take such action as agent on its behalf and to exercise such powers and
discretion under the Credit Agreement, the other Loan Documents or any other
instrument or document furnished pursuant hereto or thereto as are delegated to
the Administrative Agent and the Operations Agent by the terms thereof, together
with such powers as are incidental thereto; and (e) agrees that it will be bound
by the provisions of the Credit Agreement and will perform in accordance with
its terms all the obligations which by the terms of the Credit Agreement are
required to be performed by it as a Lender including, if it is organized under
the laws of a jurisdiction outside the United States, its obligation pursuant to
subsection 2.13(b) of the Credit Agreement.

                  4. Following the execution of this Assignment and Acceptance,
it will be delivered to the Administrative Agent for acceptance by it and
recording by the Operations Agent pursuant to the Credit Agreement, effective as
of the Effective Date (which shall not, unless otherwise agreed to by the
Administrative Agent, be earlier than five Business Days after the date of such
acceptance by the Administrative Agent and recording by the Operations Agent).


<PAGE>   33


                  5. Upon such acceptance and recording, from and after the
Effective Date, the Operations Agent shall make all payments in respect of the
Assigned Interest (including payments of principal, interest, fees and other
amounts) to the Assignee whether such amounts have accrued prior to the
Effective Date or accrue subsequent to the Effective Date. The Assignor and the
Assignee shall make all appropriate adjustments in payments by the Operations
Agent for periods prior to the Effective Date or with respect to the making of
this assignment directly between themselves.

                  6. From and after the Effective Date, (a) the Assignee shall
be a party to the Credit Agreement and, to the extent provided in this
Assignment and Acceptance, have the rights and obligations of a Lender
thereunder and under the other Loan Documents and shall be bound by the
provisions thereof and (b) the Assignor shall, to the extent provided in this
Assignment and Acceptance, relinquish its rights and be released from its
obligations under the Credit Agreement.

                  7. This Assignment and Acceptance shall be governed by and
construed in accordance with the laws of the State of New York.

                                   REPORT OF
                            INDEPENDENT ACCOUNTANTS

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

To the Shareholders and Board of Trustees of AIM Floating Rate Fund (formerly GT
Global Floating Rate Fund, Inc.):

In our opinion, the accompanying statement of assets and liabilities, including
the portfolio of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of the AIM Floating Rate Fund at
December 31, 1998, and the results of its operations, the changes in its net
assets and the financial highlights for the periods indicated, in conformity
with generally accepted accounting principles. These financial statements and
financial highlights (hereafter referred to as "financial statements") are the
responsibility of the Fund's management; our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these financial statements in accordance with generally accepted
auditing standards which require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits, which included confirmation of investments owned at December 31, 1998 by
correspondence with the custodian and brokers, provide a reasonable basis for
the opinion expressed above.

       {.:}  Senior secured corporate loans and senior secured debt securities
             in the Fund's portfolio generally have variable rates which adjust
             to a base, such as the London Inter-Bank Offered Rate ("LIBOR"), on
             set dates, typically every 30 days but not greater than one year;
             and/or have interest rates that float at a margin above a widely
             recognized base lending rate such as the Prime Rate of a designated
             U.S. bank. Senior secured floating rate interests are, at present,
             not readily marketable and may be subject to restrictions on
             resale.
       {/\}  Senior secured floating rate interests often require prepayments
             from excess cash flow or permit the borrower to repay at its
             election. The degree to which borrowers repay, whether as a
             contractual requirement or at their election, cannot be predicted
             with accuracy. As a result, the actual remaining maturity may be
             substantially less than the stated maturities shown. However, it is
             anticipated that the senior secured floating rate interests will
             have an expected average life of three to five years.

                              FINANCIAL STATEMENTS
                               December 31, 1998

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

1. SIGNIFICANT ACCOUNTING POLICIES
GT Global Floating Rate Fund, Inc., d/b/a AIM Floating Rate Fund (the "Fund"),
is organized as a Maryland corporation and is registered under the Investment
Company Act of 1940, as amended ("1940 Act"), as a continuously offered
non-diversified, closed-end management investment company.

The Fund invests all of its investable assets in the Floating Rate Portfolio
("Portfolio"). The Portfolio is organized as a Delaware business trust and is
registered under the 1940 Act as a non-diversified, closed-end management
investment company.

The Portfolio has investment objectives, policies, and limitations substantially
identical to those of the Fund. Therefore, the financial statements of the Fund
and the Portfolio have been presented on a consolidated basis, and represent all
activities of both the Fund and the Portfolio. Through December 31, 1998, all of
the beneficial interest in the Portfolio was owned either by the Fund or INVESCO
(NY), Inc., the Portfolio's investment sub-sub-advisor which has a nominal
($100) investment in the Portfolio.

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of income and expenses during the reporting year. Actual
results could differ from those estimates. The following is a summary of
significant accounting policies in conformity with generally accepted accounting
principles consistently followed by the Fund in the preparation of the financial
statements.

(A) PORTFOLIO VALUATION
The Portfolio invests primarily in senior secured corporate loans ("Corporate
Loans") and senior secured debt securities ("Corporate Debt Securities") that
meet credit standards established by INVESCO Senior Secured Management, Inc.,
(the "Sub-Adviser"), formerly, Chancellor LGT Senior Secured Management, Inc.

When possible, A I M Advisors, Inc. (the "Manager") or the Sub-Adviser will rely
on quotations provided by banks, dealers or pricing services with respect to
Corporate Loans and Corporate Debt Securities. Whenever it is not possible to
obtain such quotes, the Sub-Adviser, subject to guidelines reviewed by the
Portfolio's Board of Trustees, values the Corporate Loans and Corporate Debt
Securities at Fair Value, which approximates market value. In valuing a
Corporate Loan or Corporate Debt Security, the Sub-Adviser considers, among
other factors, (i) the credit worthiness of the U.S. or non-U.S. Company
borrowing or issuing Corporate Debt Securities and any intermediate loan
participants, (ii) the current interest rate, period until next interest rate
reset and maturity of the Corporate Loan or Corporate Debt Security, (iii)
recent prices in the market for instruments of similar quality, rate, and period
until next interest rate reset and maturity.

(B) REPURCHASE AGREEMENTS
With respect to repurchase agreements entered into by the Portfolio, it is the
Portfolio's policy to always receive, as collateral, United States government
securities or other high quality debt securities of which the value, including
accrued interest, is at least equal to the amount to be repaid to the Portfolio
under each agreement at its maturity. Repurchase agreements are valued at cost
plus accrued interest.

(C) INTERMEDIATE PARTICIPANTS
The Portfolio invests primarily in Corporate Loans from U.S. or non-U.S.
companies (the "Borrowers"). The investment of the Portfolio in a Corporate Loan
may take the form of participation interests or assignments. If the Portfolio
purchases a participation interest from a syndicate of lenders ("Lenders") or
one of the participants in the syndicate ("Participant"), one or more of which
administers the loan on behalf of all the Lenders (the "Agent Bank"), the
Portfolio would be required to rely on the Lender that sold the participation
interest not only for the enforcement of the Portfolio's rights against the
Borrower but also for the receipt and processing of payments due to the
Portfolio under the Corporate Loans. As such, the Portfolio is subject to the
credit risk of the Borrower and a Participant. Lenders and Participants
interposed between the Portfolio and a Borrower, together with Agent Banks, are
referred to as "Intermediate Participants".

(D) INVESTMENT TRANSACTIONS
Investment transactions are accounted for on the trade date (date the order to
buy or sell is executed). The cost of investments sold is determined on a
first-in, first-out basis, unless otherwise specified. The Portfolio may trade
securities on other than normal settlement terms. This may increase the market
risk if the other party to the transaction fails to deliver and causes the
Portfolio to subsequently invest at less advantageous prices.

(E) TAXES
It is the policy of the Fund to meet the requirements for qualification as a
"regulated investment company" under the Internal Revenue Code of 1986, as
amended ("Code"). It is also the intention of the Fund to make distributions
sufficient to avoid imposition of any excise tax under Section 4982 of the Code.
Therefore, no provision has been made for Federal taxes on income, capital
gains, and unrealized appreciation of securities held, or excise tax on income
and capital gains.

(F) DISTRIBUTIONS TO SHAREHOLDERS
Distributions to shareholders from net investment income are declared daily and
paid or reinvested monthly. Income and capital gain distributions are determined
in accordance with Federal income tax regulations which may differ from
generally accepted accounting principles. These differences are primarily due to
differing treatments

                                       F-12
<PAGE>   14
of income and gains on various investment securities held by the Portfolio and
timing differences.

(G) DEFERRED ORGANIZATIONAL EXPENSES
Expenses incurred by the Fund or Portfolio in connection with its organization
aggregated $212,350. These expenses are being amortized on a straightline basis
over a five-year period.

(H) RESTRICTED SECURITIES
The Portfolio may invest all or substantially all of its assets in Corporate
Loans, Corporate Debt Securities or other securities that are rated below
investment grade by a nationally recognized statistical rating organization, or
in comparable unrated securities. The Portfolio is permitted to invest in
privately placed restricted securities. These securities may be resold in
transactions exempt from registration or to the public if the securities are
registered. Disposal of these securities may involve time-consuming negotiations
and expense, and prompt sale at an acceptable price may be difficult.

(I) SECURITIES PURCHASED ON A WHEN-ISSUED AND DELAYED
   DELIVERY BASIS
The Portfolio may purchase and sell interests in Corporate Loans and Corporate
Debt Securities and other portfolio securities on a when-issued and delayed
delivery basis, with payment and delivery scheduled for a future date. No income
accrues to the Portfolio on such interests or securities in connection with such
transactions prior to the date the Portfolio actually takes delivery of such
interests or securities. These transactions are subject to market fluctuations
and are subject to the risk that the value at delivery may be more or less than
the trade date purchase price. Although the Portfolio will generally purchase
these securities with the intention of acquiring such securities, they may sell
such securities before the settlement date. These securities are identified on
the accompanying Portfolio of Investments. The Portfolio has set aside
sufficient cash or liquid high grade debt securities as collateral for these
purchase commitments.

(J) INVESTMENT INCOME
Investment income is recorded on an accrual basis. Where a high level of
uncertainty exists as to collection of income on securities, income is recorded
net of all withholding tax with any rebate recorded when received. Facility fees
received are recognized as income over the expected life of the loan. Market
discounts are accreted over the stated life of each applicable security.

(K) LINE OF CREDIT
The Fund, along with certain other funds advised and/or administered by A I M
Advisors, Inc. ("AIM" or the "Manager"), has a line of credit with BankBoston
and State Street Bank and Trust Company. The arrangements with the banks allow
the Fund and certain other funds to borrow, on a first come, first served basis,
an aggregate maximum amount of $250,000,000. The Fund is limited to borrowing up
to 33 1/3% of the value of the Fund's total assets. On December 31, 1998, the
Fund had no outstanding loan balance.

For the year ended December 31, 1998, the weighted average outstanding daily
balance of bank loans (based on the number of days the loans were outstanding)
was $2,799,958 with a weighted average interest rate of 6.21%. Interest expense
for the year ended was $11,594.

transaction, Chancellor LGT was renamed INVESCO (NY), Inc., Senior Secured was
renamed INVESCO Senior Secured Management, Inc., and each of them is now an
indirect wholly-owned subsidiary of AMVESCAP PLC. A I M Distributors, Inc. ("AIM

such Fund's average daily net assets. The Portfolio pays investment management
and administration fees to the Manager at the annualized rate of 0.95% of the
Portfolio's average daily net assets.

AIM Distributors serves as the Fund's distributor. For the year ended May 29,
1998, GT Global, Inc. ("GT Global") served as the Fund's distributor.

Certain redemptions of common shares made within four years of purchase are
subject to an early withdrawal charge, in accordance with the fund's current
prospectus. For the period ended December 31, 1998, AIM Distributors and GT
Global collected early withdrawal charges in the amount of $475,585 and $77,982,
respectively for the Fund.

The Manager and AIM Distributors have undertaken to limit the Fund's expenses
(exclusive of brokerage commissions, taxes, interest, and extraordinary
expenses) to the maximum annual rate of 1.50% of the average daily net assets of
the Fund.

Effective as of the close of business September 4, 1998, the Fund, pursuant to a
transfer agency and service agreement, has agreed to pay AFS an annualized fee

billed by AFS monthly in arrears on a prorated basis of 1/12 of the annualized
fee for all such accounts.

For the period January 1, 1998 to September 4, 1998, GT Services, an affiliate
of the Manager and AIM Distributors, was the transfer agent of the Fund. For
performing shareholder servicing, reporting, and general transfer agent
services, GT Services received an annual maintenance fee of $17.50 per account,
a new account fee of $4.00 per account, a per transaction fee of $1.75 for all
transactions other than exchanges and a per exchange fee of $2.25. GT Services
was also reimbursed by the Fund for its out-of-pocket expenses for such items as
postage, forms, telephone charges, stationery and office supplies.

The Manager is the pricing and accounting agent for the Fund. The monthly fee
for these services to the Manager is a percentage, not to exceed 0.03% annually,
of the Fund's average daily net assets. The annual fee rate is derived based on
the aggregate net assets of the funds which comprise the following investment
companies: AIM Growth Series, AIM Investment Funds, AIM Investment Portfolios,
AIM Series Trust, G.T. Global Variable Investment Series and G.T. Global
Variable Investment Trust. The fee is calculated at the rate of 0.03% to the
first $5 billion of assets and 0.02% to the assets in excess of $5 billion. An
amount is allocated to and paid by each such fund based on its relative average
daily net assets.

The Trust pays each of its Trustees who is not an employee, officer or director
of the Manager, AIM Distributors or GT Services $5,000 per year plus $300 for
each meeting of the board or any committee thereof attended by the Trustee.
