         The  Portfolio  is  managed  by A I M  Advisors,  Inc.  ("AIM")  and is
sub-advised by INVESCO Senior Secured Management, Inc. (the "Sub-advisor").  The
Sub-advisor  has  appointed   INVESCO  (NY),  Inc.   ("INVESCO   (NY)")  as  the

Sub-advisor  and INVESCO (NY) are all  indirect  wholly  owned  subsidiaries  of
AMVESCAP  PLC  ("AMVESCAP").  On May  29,  1998,  AMVESCAP  acquired  the  Asset
Management  Division  of  Liechtenstein  Global  Trust AG,  which  included  the
Sub-advisor and certain other  affiliates.  AMVESCAP and its subsidiaries are an
independent  investment  management group that has a significant presence in the
institutional and retail segment of the investment  management industry in North
America and Europe, and a growing presence in Asia.

ITEM 10.    CAPITAL STOCK, LONG-TERM DEBT, AND OTHER SECURITIES.

ITEM 10.1.  CAPITAL STOCK.

         The  Portfolio  is  organized as a trust under the laws of the State of
Delaware and intends to be classified as a partnership  for income tax purposes.
Under the Trust Instrument,  the Portfolio shall consist of one or more separate
and distinct  series.  Additional  series shall be established  by, and shall be
effective  upon, the adoption of a resolution by the trustees.  The trustees may
designate the relative  rights and  preferences of the interests of each series.
The Portfolio shall maintain  separate and distinct  records for each series.  A
series may issue any number of interests. Each holder of an interest in a series
shall be entitled to receive its pro rata share of all  distributions  made with
respect to that series.  On redemption  of an interest in a series,  an interest
holder shall be paid solely out of the assets belonging to that series.

         The  beneficial  interest  in  the  Portfolio  shall  be  divided  into
interests in one or more series.  The number of interests in the  Portfolio  and
each series shall be unlimited.  All interests  issued by the Portfolio shall be
fully paid and nonassessable. Interest holders shall have no preemptive or other
rights to subscribe to any additional  interests or other  securities  issued by
the Portfolio.  The trustees shall have full power and authority,  in their sole

                                      A-2
<PAGE>

discretion and without obtaining interest holder approval, (a) to issue original
or additional  interests at such times and on such terms and  conditions as they
deem appropriate,  (b) to establish and to change in any manner interests in any
series with such preference,  terms of conversion,  voting powers,  rights,  and
privileges  as the  trustees  may  determine  (but the  trustees  may not change
interests in a manner materially adverse to the interest holders), (c) to divide
or combine the interests in any series into a greater or lesser  number,  (d) to
classify or  reclassify  any  unissued  interests of any series into one or more
series, (e) to abolish any one or more series, (f) to issue interests to acquire
other  assets  (including  assets  subject  to,  and  in  connection  with,  the
assumption of liabilities) and businesses and (g) to take such other action with
respect to the interests as the trustees may deem desirable.

         The trustees  shall accept  investments in any series from such persons
and on such terms as they may from time to time authorize. At the trustees' sole
discretion,  such investments,  subject to applicable law, may be in the form of
cash or securities  in which that series is  authorized to invest.  The trustees
shall have the right to refuse to accept  investments  in any series at any time
without any cause or reason therefor whatsoever. Notwithstanding anything in the
Portfolio's  Trust  Instrument to the contrary,  (a) interests  shall be only be
issued in a transaction or  transactions  not requiring  registration  under the
1933 Act and (b) no  series  shall  at any  time  have  more  than 100  interest
holders.  In determining the number of interest  holders of any series, a person
owning an interest  through a  partnership,  grantor trust or S  corporation  (a
"flow-through  entity") shall be counted as a interest  holder if  substantially
all  the  value  of  that  person's  interest  in  the  flow-through  entity  is
attributable to that series and a principal purpose for using a tiered structure
was to satisfy the 100-interest holder condition. The trustees shall impose such
other  limitations on investments in the series as are necessary to avoid having
any series  treated as a  "publicly  traded  partnership"  within the meaning of
Section 7704 of the Code.

         The  Portfolio or any series may be  terminated  by a majority  vote of
interest holders of the Portfolio or the affected series,  respectively,  or the
trustees  by  written  notice  to the  interest  holders.  Any  series  shall be
terminated 120 days after an interest  holder in that series either (i) makes an
assignment  for the benefit of  creditors,  (ii) files a  voluntary  petition in
bankruptcy,  (iii) is  adjudicated  a  bankrupt  or  insolvent,  (iv)  files any
pleading admitting or failing to contest the material  allegations of a petition
filed  against  it in any  bankruptcy  or  insolvency  proceeding  or (v) seeks,
consents  to, or  acquiesces  in the  appointment  of a  trustee,  receiver,  or
liquidator  of the  interest  holder  or of all or any  substantial  part of its
assets,  unless,  within such 120 days, interest holders (excluding the interest
holder  with  respect  to whom  such  event  occurs)  owning a  majority  of the
interests in that series vote to continue that series.

         The trustees may, without interest holder approval, cause the Portfolio
or any series to merge or consolidate with or into any other entity or entities.
Any agreement of merger or  consolidation or certificate of merger may be signed
by a majority of trustees,  and facsimile  signatures  conveyed by electronic or
telecommunication means shall be valid.

         The  trustees  may,  without the prior  consent or vote of the interest
holders,  (i) cause to be organized or assist in  organizing  a  corporation  or
corporations under the laws of any jurisdiction or any other trust, partnership,
association, or other organization (each, a "successor entity") to take over all
of the trust  property or the assets  belonging to any series or to carry on any
business in which the trust or any series shall directly or indirectly  have any

                                      A-3
<PAGE>

interest,  (ii) sell,  convey, and transfer the Portfolio property or the assets
belonging to any series to any such successor  entity in exchange for the equity
interests thereof or otherwise and (iii) lend money to, subscribe for the equity
interests in, and enter into any contracts with, any such successor entity.

        The Board of Trustees of the Portfolio has an Audit Committee, comprised
of Miss Quigley and Messrs. Anderson, Bayley and Patterson, which is responsible
for reviewing and evaluating the audit function, including recommending firms to
serve as independent auditors of the Portfolio.  Each trustee and officer of the
Portfolio is also a director  and/or trustee and officer,  respectively,  of the
other investment companies registered under the 1940 Act that are managed by AIM
and that may be sub-advised and/or sub-administered by the Sub-Advisor,  INVESCO
(NY), INVESCO Asset Management Limited, INVESCO Asset Management (Japan) Limited
or INVESCO  Asia  Limited.  For the fiscal year ended  December  31,  1998,  the
Portfolio  paid Mr.  Anderson,  Mr.  Bayley,  Mr.  Patterson  and  Miss  Quigley
Trustees' fees and expense  reimbursements of $6,650, $5,450, $6,050 and $6,650,
respectively.  Mr. Anderson, Mr. Bayley, Mr. Patterson and Miss Quigley, who are
not  directors,  officers or employees of AIM or any  affiliated  company,  each
received  total  compensation  of  $106,850,   $90,650,   $98,600  and  $99,500,
respectively,  from the investment companies that are managed or administered by
AIM for which he or she  serves  as a  Director  or  Trustee.  Fees and  expense
disbursed to the Trustees contained no accrued or payable pension, or retirement
benefits.  Other  trustees  and  officers  receive  no  compensation  or expense
reimbursement from the Portfolio. As of April 1, 1999, the officers and Trustees
and their families as a group owned in the aggregate  beneficially  or of record
less  than 1% of the  outstanding  interests  of the  Portfolio.  The  Portfolio
requires  no  employees  since the  Sub-advisor  and other  third-party  service
providers  perform   substantially  all  of  the  services   necessary  for  the
Portfolio's operations.

ITEM 19.          CONTROL PERSONS AND PRINCIPAL HOLDERS OF SECURITIES.

         The Fund  invests  substantially  all of its  assets in the  Portfolio.
Because the Fund controls the Portfolio, the Fund may take actions affecting the
Portfolio without the approval of any other investor.

         The Fund has informed the  Portfolio  that  whenever it is requested to
vote on any proposal of the  Portfolio,  it will hold a meeting of  shareholders
and will cast its vote as instructed by its shareholders. It is anticipated that
any  other  investors  in the  Portfolio  would  follow  the  same or a  similar
practice.

         The address of the Fund is 11 Greenway Plaza, Suite 100, Houston, Texas
77046.

To the Shareholders and Board of Trustees of AIM Floating Rate Portfolio
(formerly GT Global Floating Rate Portfolio, 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, cash flows and the supplementary data present fairly, in
all material respects, the financial position of the AIM Floating Rate Portfolio
at December 31, 1998, and the results of its operations, the changes in its net
assets, cash flows and the supplementary data for the periods indicated, in
conformity with generally accepted accounting principles. These financial
statements and supplementary data (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.

</TABLE>
         --------------
         {.:}  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.

1. SIGNIFICANT ACCOUNTING POLICIES
Floating Rate Portfolio ("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 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 Portfolio to meet the requirements for qualification as
a "regulated investment company" under the Internal Revenue Code of 1986, as
amended ("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) DEFERRED ORGANIZATIONAL EXPENSES
Expenses incurred by the Portfolio in connection with its organization
aggregated $95,995. These expenses are being amortized on a straightline basis
over a five-year period.

                                       B-15
<PAGE>

(G) 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.

(H)  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.


(I) 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.

                                    ARTICLE V
                               MEETINGS OF HOLDERS

         Section 1.   No Annual Meetings.
                      ------------------

         There shall be no annual meeting of Holders, unless required by law.

         Section 2.   Special Meetings.
                      ----------------

         The Secretary  shall call a special meeting of Holders of any Series or
Class whenever ordered by the Trustees.

         The  Secretary  also  shall  call a special  meeting  of Holders of any
Series or Class upon the written  request of Holders owning at least ten percent
of the  Outstanding  Interests of such Series or Class  entitled to vote at such
meeting;  provided,  that (1) such  request  shall  state the  purposes  of such
meeting and the matters proposed to be acted on, and (2) the Holders  requesting
such  meeting  shall  have paid to the Trust the  reasonably  estimated  cost of
preparing and mailing the notice  thereof,  which the Secretary  shall determine
and specify to such Holders. If the Secretary fails for more than thirty days to
call a special  meeting  when  required  to do so, the  Trustees  or the Holders
requesting such a meeting may, in the name of the Secretary, call the meeting by
giving the required notice.  The Secretary shall not call a special meeting upon
the  request of Holders of any Series or Class to  consider  any matter  that is
substantially  the same as a matter voted upon at any special meeting of Holders
of such  Series  or Class  held  during  the  preceding  twelve  months,  unless
requested  by the holders of a majority  of the  Outstanding  Interests  of such
Series or Class entitled to be voted at such meeting.

         A special  meeting of  Holders of any Series or Class  shall be held at
such time and place as is determined by the Trustees and stated in the notice of
that meeting.

         Section 3.   Notice of Meetings; Waiver.
                      --------------------------

         The Secretary shall call a special meeting of Holders by giving written
notice of the place,  date,  time, and purposes of that meeting at least fifteen
days before the date of such meeting. The Secretary may deliver or mail, postage
prepaid,  the written  notice of any meeting to each Holder  entitled to vote at
such meeting.  If mailed,  notice shall be deemed to be given when  deposited in
the  United  States  mail  directed  to the  Holder at his or her  address as it
appears on the records of the Trust.

         Section 4.   Adjourned Meetings.
                      ------------------

         A meeting of Holders may be adjourned one or more times for any reason,


                                       4
<PAGE>

including the failure of the presence of a quorum to attending  the meeting.  No
notice of  adjournment  of a meeting to  another  time or place need be given to
Holders  if such  time and  place  are  announced  at the  meeting  at which the
adjournment  is taken or  reasonable  notice is given to persons  present at the
meeting, and if the adjourned meeting is held within a reasonable time after the
date set for the original meeting.  Any business that might have been transacted
at the original meeting may be transacted at any adjourned meeting. If after the
adjournment a new record date is fixed for the adjourned meeting,  the Secretary
shall give notice of the adjourned meeting to Holders of record entitled to vote
at  such  meeting.  Any  irregularities  in the  notice  of any  meeting  or the
nonreceipt  of any such notice by any of the Holders  shall not  invalidate  any
action otherwise properly taken at any such meeting.

         Section 5.   Validity of Proxies.
                      -------------------

         At all  meetings of Holders,  every  Holder of record  entitled to vote
thereat shall be entitled to vote either in person or by proxy, which term shall
include proxies provided through written, electronic, telephonic,  computerized,
facsimile, telecommunications,  telex or oral communication or by any other form
of  communication,  each  pursuant to such voting  procedures  and through  such
systems as are authorized by the Trustees or one or more  executive  officers of
the Trust. Unless the proxy provides  otherwise,  it shall not be valid for more
than  eleven  months  prior to the date of the  meeting.  All  proxies  shall be
delivered  to the  Secretary  or other  person  responsible  for  recording  the
proceedings  before being voted.  A proxy with respect to Interests  held in the
name of two or more persons  shall be valid if executed by one of them unless at
or prior to exercise of such proxy the Trust receives a specific  written notice
to the contrary from any one of them. Unless otherwise  specifically  limited by
their terms,  proxies shall entitle the Holder to vote at any  adjournment  of a
meeting of  Holders.  A proxy  purporting  to be  executed  by or on behalf of a
Holder shall be deemed valid unless challenged at or prior to its exercise,  and
the burden of proving invalidity shall rest on the challenger.  At every meeting
of Holders,  unless the voting is conducted by  inspectors,  the chairman of the
meeting shall decide all questions  concerning the qualifications of voters, the
validity of proxies,  and the  acceptance or rejection of votes.  Subject to the
provisions of the Delaware  Business Trust Act, the Trust  Instrument,  or these
Amended  and  Restated  By-Laws,  the  General  Corporation  Law of the State of
Delaware  relating to proxies,  and judicial  interpretations  thereunder  shall
govern all matters concerning the giving,  voting or validity of proxies,  as if
the Trust were a Delaware  corporation  and the Holders were  shareholders  of a
Delaware corporation.

         Section 6.   Record Date.
                      -----------

         The  Trustees  may fix in advance a date up to ninety days prior to the
date of any  meeting of Holders as a record  date for the  determination  of the
Holders entitled to notice of, and to vote at, any such meeting.  The Holders of
record  entitled to vote at a meeting of Holders  shall be deemed the Holders of
record at any  meeting  reconvened  after one or more  adjournments,  unless the
Trustees  have fixed a new record  date.  If the meeting of Holders is adjourned
for more than sixty days after the original date, the Trustees shall establish a
new record date.

         Section 7.   Action Without a Meeting.
                      ------------------------

         Holders  may take any action  without a meeting if a majority  (or such
greater amount as may be required by law) of the Outstanding  Interests entitled
to vote on the matter consent to the action in writing and such written consents
are filed with the records of Holders'  meetings.  Such written consent shall be
treated for all purposes as a vote at a meeting of the Holders.

certifying  the  ownership  of  Interests,  unless the  Trustees  may  otherwise
specifically authorize such certificates.

         Section 2.   Transfer of Interests.
                      ---------------------

         Interests  shall be  transferable  only by a transfer  recorded  on the
books of the  Trust by the  Holder  of  record  in  person or by his or her duly
authorized attorney or legal representative. Interests may be freely transferred
and the Trustees may, from time to time,  adopt rules and regulations  regarding
the method of transfer of such Interests.

Instrument ("Custodian").  The Custodian shall be appointed from time to time by
the Board of Trustees, who shall determine its remuneration.

         Section 2.   Termination of Custodian Agreement.

                             FLOATING RATE PORTFOLIO

                INVESTMENT MANAGEMENT AND ADMINISTRATION CONTRACT
                                     BETWEEN
                             FLOATING RATE PORTFOLIO
                                       AND
                              A I M ADVISORS, INC.


        Contract  made as of May  29,  1998,  between  Floating  Rate  Portfolio
("Portfolio"),  a  Delaware  business  trust,  and  A I M  Advisors,  Inc.  (the
"Adviser"), a Delaware corporation.

        WHEREAS the Portfolio is registered under the Investment  Company Act of
1940, as amended ("1940 Act"), as a closed-end  management  investment  company;
and

        WHEREAS the Portfolio  desires to retain  Adviser as investment  manager
and  administrator to furnish certain  administrative,  investment  advisory and
portfolio  management  services  to the  Portfolio,  and  Adviser  is willing to
furnish such services;

        NOW,  THEREFORE,  in  consideration  of  the  premises  and  the  mutual
covenants herein contained, it is agreed between the parties hereto as follows:

1.    APPOINTMENT.  The Portfolio hereby appoints Adviser as investment  manager
and  administrator  for the period  and on the term set forth in this  Contract.
Adviser  accepts such  appointment  and agrees to render the services herein set
forth, for the compensation herein provided.

2.    DUTIES AS INVESTMENT MANAGER.

      (a)  Subject  to the  supervision  of the  Portfolio's  Board of  Trustees
("Board"),  Adviser  will  provide  a  continuous  investment  program  for  the
Portfolio,  including  investment  research and  management  with respect to all
securities and investments and cash  equivalents of the Portfolio.  Adviser will
determine  from  time to time what  securities  and  other  investments  will be
purchased,  retained  or sold by the  Portfolio,  and the  brokers  and  dealers
through whom trades will be executed.

      (b) Adviser agrees that in placing orders with brokers and dealers it will
attempt  to  obtain  the best net  results  in  terms  of price  and  execution.
Consistent  with this obligation  Adviser may, in its  discretion,  purchase and
sell portfolio securities to and from brokers and dealers who sell shares of the
Portfolio or provide the  Portfolio's or Adviser's  other clients with research,
analysis,  advice and similar services.  Adviser may pay to brokers and dealers,
in return for research and analysis,  a higher  commission or spread than may be
charged by other brokers and dealers,  subject to Adviser's  determining in good
faith  that  such  commission  or spread is  reasonable  in terms  either of the
particular  transaction  or of the  overall  responsibility  of  Adviser  to the
Portfolio and its other clients and that the total  commissions  or spreads paid
by the Portfolio will be reasonable in relation to the benefits to the Portfolio

<PAGE>

over the long term. In no instance will  portfolio  securities be purchased from
or sold to Adviser or any affiliated  person  thereof except in accordance  with
the federal  securities  laws and the rules and  regulations  thereunder and any
exemptive orders currently in effect.  Whenever  Adviser  simultaneously  places
orders to purchase or sell the same  security on behalf of the Portfolio and one
or more other accounts  advised by Adviser,  such orders will be allocated as to
price and amount among all such accounts in a manner believed to be equitable to
each account.  The Portfolio  recognizes that in some-cases.  this procedure may
adversely affect the results obtained for the Portfolio.

      (c) Adviser  will  oversee the  maintenance  of all books and records with
respect to the securities  transactions  of the Portfolio,  and will furnish the
Board  with such  periodic  and  special  reports  as the Board  reasonably  may
request.  In compliance with the  requirements of Rule 31a-3 under the 1940 Act,
Adviser  hereby agrees that all records which it maintains for the Portfolio are
the property of the Portfolio,  agrees to preserve for the periods prescribed by
Rule 31a-2 under the 1940 Act any records  which it maintains  for the Portfolio
and which are  required to be  maintained  by Rule 31a-1 under the 1940 Act, and
further  agrees to  surrender  promptly to the  Portfolio  any records  which it
maintains for the Portfolio upon request by the Portfolio.

3.    DUTIES AS  ADMINISTRATOR.  Adviser  will  administer  the  affairs  of the
Portfolio   subject  to  the   supervision   of  the  Board  and  the  following
understandings:

      (a) Adviser will supervise all aspects of the operations of the Portfolio,
including the oversight of transfer  agency and  custodial  services,  except as
hereinafter set forth; provided, however, that nothing herein contained shall be
deemed to relieve or deprive the Board of its  responsibility for control of the
conduct of the affairs of the Portfolio.

      (b) At Adviser's  expense,  Adviser will provide the  Portfolio  with such
corporate,  administrative  and clerical  personnel  (including  officers of the
Portfolio) and services as are reasonably  deemed  necessary or advisable by the
Board.

      (c) Adviser  will  arrange,  but not pay,  for the  periodic  preparation,
updating,  filing and  dissemination  (as applicable) of the  Portfolio's  proxy
material,   tax  returns  and  required  reports  with  or  to  the  Portfolio's
shareholders,  the  Securities  and Exchange  Commission  and other  appropriate
federal or state regulatory authorities.

      (d) Adviser will provide the Portfolio  with,  or obtain for it,  adequate
office  space  and  all  necessary  office  equipment  and  services,  including
telephone service, heat, utilities, stationery supplies and similar items.

4. FURTHER DUTIES.  In all matters relating to the performance of this Contract,
Adviser will act in  conformity  with the Agreement  and  Declaration  of Trust,
By-Laws and  Registration  Statement of the Portfolio and with the  instructions
and  directions of the Board and will comply with the  requirements  of the 1940
Act, the rules thereunder,  and all other applicable  federal and state laws and
regulations.

5. DELEGATION OF ADVISER'S DUTIES AS INVESTMENT MANAGER AND ADMINISTRATOR.  With
respect  to  the  Portfolio,  Adviser  may  enter  into  one or  more  contracts
("Sub-Advisory or Sub-Administration Contract") with a Sub-Adviser or

<PAGE>

Sub-Administrator   in  which   Adviser   delegates  to  such   sub-adviser   or
sub-administrator  the  performance  of any or-all of the services  specified in
Paragraphs 2 and 3 of this Contract,  provided that: (i) each  Sub-Advisory  and
Sub-Administration  Contract  imposes on the  sub-adviser  or  sub-administrator
bound  thereby all the duties and  conditions  to which  Adviser is subject with
respect to the services under Paragraphs 2, 3 and 4 of this Contract;  (ii) each
Sub-Advisory and Sub-Administration  Contract meets all requirements of the 1940
Act and rules thereunder;  and (iii) Adviser shall not enter into a Sub-Advisory
or  Sub-Administration  Contract  unless it is  approved  by the Board  prior to
implementation.

not to be deemed exclusive and Adviser shall be free to furnish similar services
to others so long as its services under this Contract are not impaired  thereby.

        NOW THEREFORE, in consideration of the promises and the mutual covenants
herein  contained,  it is agreed  between  the  parties  hereto as  follows:  

      1.  APPOINTMENT.  Adviser hereby  appoints  Sub-Adviser as sub-adviser and
sub-administrator  of the Portfolio for the period and on the terms set forth in
this Contract.  Sub-Adviser  accepts such  appointment  and agrees to render the
services herein set forth, for the compensation herein provided.

      2. DUTIES AS SUB-ADVISER.

      (a)  Subject  to the  supervision  of the  Portfolio's  Board of  Trustees
("Board")  and Adviser,  the  Sub-Adviser  will provide a continuous  investment
program for the Portfolio,  including  investment research and management,  with
respect to all securities and investments and cash equivalents of the Portfolio.
The Sub-Adviser will determine from time to time what securities and investments
will be  purchased,  retained  or sold by the  Portfolio,  and the  brokers  and
dealers through whom trades will be executed.

      (b) The  Sub-Adviser  agrees  that,  in placing  orders  with  brokers and
dealers,  it will  attempt to obtain the best net  results in terms of price and
execution.  Consistent  with  this  obligation,  the  Sub-Adviser  may,  in  its
discretion,  purchase  and sell  portfolio  securities  from and to brokers  and
dealers who provide the Portfolio's,  Adviser's,  or Sub-Adviser's other clients
with research,  analysis,  advice and similar services. The Sub-Adviser may pay,
in return for such services research and analysis, a higher commission or spread

<PAGE>

than may be charged by other brokers and dealers,  subject to the  Sub-Adviser's
determining in good faith that such  commission or spread is reasonable in terms
either of the  particular  transaction or of the overall  responsibility  of the
Sub-Adviser  to  the  Portfolio  and  its  other  clients  and  that  the  total
commissions  or spreads paid by the Portfolio  will be reasonable in relation to
the benefits to the Portfolio  over the long term. In no instance will Portfolio
securities  be  purchased  from or sold to the  Sub-Adviser,  or any  affiliated
person thereof,  except in accordance  with the federal  securities laws and the
rules and regulations  thereunder and any exemptive  orders currently in effect.
Whenever the  Sub-Adviser  simultaneously  places orders to purchase or sell the
same security on behalf of the Portfolio and one or more other accounts  advised
by the  Sub-Adviser,  such orders will be allocated as to price and amount among
all such  accounts in a manner  believed to be  equitable to each  account.  The
Portfolio  recognizes that in some cases this procedure may adversely affect the
results obtained for the Portfolio.

      (c) The  Sub-Adviser  will  maintain all books and records with respect to
the securities  transactions  of the  Portfolio,  and will furnish the Board and
Adviser  with  such  periodic  and  special  reports  as the  Board  or  Adviser
reasonably may request.  In compliance with the requirements of Rule 31a-3 under
the 1940 Act, the Sub-Adviser  hereby agrees that all records which it maintains
for the Portfolio are the property of the Portfolio,  agrees to preserve for the
periods  prescribed  by Rule  31a-2  under  the  1940 Act any  records  which it
maintains  for the  Portfolio  and which are required to be  maintained  by Rule
31a-1  under the 1940 Act,  and  further  agrees to  surrender  promptly  to the
Portfolio any records  which it maintains for the Portfolio  upon request by the
Portfolio.

      3. DUTIES AS SUB-ADMINISTRATOR. Sub-Adviser will administer the affairs of
the Portfolio  subject to the supervision of the  Portfolio's  Board of Trustees
("Board"), the Adviser, and the following understandings:

      (a)  Sub-Adviser  will  supervise  all  aspects of the  operations  of the
Portfolio,  including  the oversight of transfer  agency and custodial  services
except  as  hereinafter  set  forth;  provided,  however,  that  nothing  herein
contained shall be deemed to relieve or deprive the Board of its  responsibility
for control of the conduct of the affairs of the Portfolio. 

      (b) At Sub-Adviser's expense,  Sub-Adviser will provide the Portfolio with
such corporate, administrative and clerical personnel (including officers of the
Portfolio) and services as are reasonably  deemed  necessary or advisable by the
Board. 

      (c) Sub-Adviser will arrange,  but not pay, for the periodic  preparation,
updating,   filing  and   dissemination   (as  applicable)  of  the  Portfolio's
prospectus,  proxy  material,  tax returns and  required  reports with or to the
Portfolio's  shareholders,  the  Securities  and Exchange  Commission  and other
appropriate  federal  or state  regulatory  authorities.  

      (d)  Sub-Adviser  will  provide  the  Portfolio  with,  or obtain  for it,
adequate office space and all necessary office equipment and services, including
telephone service,  heat,  utilities,  stationery supplies and similar items.

<PAGE>

      4. FURTHER  DUTIES.  In all matters  relating to the  performance  of this
Contract,  Sub-Adviser will act in conformity with the Agreement and Declaration
of Trust,  By-Laws and  Registration  Statement  of the  Portfolio  and with the
instructions  and directions of the Board and will comply with the  requirements
of the 1940 Act,  the rules  thereunder,  and all other  applicable  federal and
state laws and regulations. 

      5.    DELEGATION   OF    SUB-ADVISER'S    DUTIES   AS   SUB-ADVISER    AND
SUB-ADMINISTRATOR. With respect to the Portfolio, Sub-Adviser may enter into one
or more contracts ("Sub-Sub-Advisory or Sub-Sub-Administration  Contracts") with
a sub-sub-adviser  or  sub-sub-administrator  in which Sub-Adviser  delegates to
such sub-sub-adviser or  sub-sub-administrator  the performance of any or all of
the services  specified in Paragraphs 2 and 3 of this  Contract,  provided that:
(i) each  Sub-Sub-Advisory  and  Sub-Sub-Administration  Contract imposes on the
sub-sub-adviser  or  sub-sub-administrator  bound  thereby  all the  duties  and
conditions to which  Sub-Adviser  is subject with respect to the services  under
Paragraphs  2,  3  and  4 of  this  Contract;  (ii)  each  Sub-Sub-Advisory  and
Sub-Sub-Administration Contract meets all requirements of the 1940 Act and rules
thereunder,  and  (iii)  Adviser  shall  not enter  into a  Sub-Sub-Advisory  or
Sub-Sub-Administration  Contract  unless it is  approved  by the Board  prior to
implementation. 

      6. SERVICES NOT EXCLUSIVE. The services furnished by Sub-Adviser hereunder
are not to be deemed exclusive and Sub-Adviser  shall be free to furnish similar
services to others so long as its services  under this Contract are not impaired
thereby.  Nothing in this  Contract  shall  limit or  restrict  the right of any
director, officer or employee of Sub-Adviser, who may also be a Trustee, officer
or employee of the  Portfolio,  to engage in any other business or to devote his
or her time and  attention  in part to the  management  or other  aspects of any
other business, whether of a similar nature or a dissimilar nature.

or become a  Trustee,  officer,  employee  or agent of the  Portfolio,  shall be
deemed,  when rendering  services to the Portfolio or acting with respect to any

the Portfolio and not as an officer,  partner,  employee,  or agent or one under
the control or direction of Sub-Adviser even though paid by it.

      10.  DURATION AND TERMINATION.

      (a) This Contract shall become effective upon the date hereabove  written,

Trustees,  cast in person at a meeting  called for the purpose of voting on such
approval,  and (ii) by the  Board or by vote of a  majority  of the  outstanding

will automatically  terminate in the event of its assignment.

      11.  AMENDMENT.  No  provision of this  Contract  may be changed,  waived,
discharged or terminated  orally, but only by an instrument in writing signed by

      13.  MISCELLANEOUS.  The  captions  in  this  Contract  are  included  for
convenience  of  reference  only  and in no way  define  or  delimit  any of the
provisions  hereof or otherwise  affect  their  construction  or effect.  If any
provision of this  Contract  shall be held or made invalid by a court  decision,
statute, rule or otherwise, the remainder of this Contract shall not be affected
thereby.  This Contract  shall be binding upon and shall inure to the benefit of

              SUB-SUB-ADVISORY AND SUB-SUB-ADMINISTRATION CONTRACT
                                     BETWEEN

                               INVESCO (NY), INC.

      Contract  made  as  of  May  29,  1998,  between  INVESCO  Senior  Secured
Management,  Inc., a New York  corporation  ("Sub-Adviser"),  and INVESCO  (NY),
INC., a California corporation ("Secondary Sub-Adviser").

      WHEREAS Sub-Adviser has entered into a Sub-Advisory and Sub-Administration
Contract  with A I M Advisors,  Inc.  ("Adviser")  with respect to Floating Rate
Portfolio  (`Portfolio"),  a closed-end management investment company registered
under the Investment Company Act of 1940, as amended ("1940 Act"); and

      WHEREAS   Sub-Adviser   desires  to  retain   Secondary   Sub-Adviser   as
sub-sub-adviser  and  sub-sub-administrator  to  furnish  certain  advisory  and
administrative  services to the Portfolio,  and Secondary Sub-Adviser is willing
to furnish such services;

      NOW THEREFORE,  in  consideration of the promises and the mutual covenants
herein  contained,  it is agreed  between  the  parties  hereto as  follows:  

      1.  APPOINTMENT.  Sub-Adviser  hereby  appoints  Secondary  Sub-Adviser as
sub-sub-adviser and sub-sub-administrator of the Portfolio for the period and on
the  terms  set  forth in this  Contract.  Secondary  Sub-Adviser  accepts  such

("Board"),  Adviser, and the Sub-Adviser, the Secondary Sub-Adviser will provide
a continuous investment program for the Portfolio, including investment research
and  management,  for a  portion  of  the  investments  of the  Portfolio  to be
determined by the  Sub-Adviser  (the  "Sub-Sub-Advised  Assets").  The Secondary

Sub-Sub-Advised  Assets of the  Portfolio.  The  Secondary  Sub-Adviser  will be
responsible  for placing  purchase and sell orders for such  investments and for
other related  transactions.  The Secondary  Sub-Adviser  will provide  services
under this Agreement in accordance with the Portfolio's  investment  objectives,
policies and restrictions as stated in the Portfolio's  registration  statement.

      (b) The Secondary  Sub-Adviser  agrees that in placing orders with brokers

and dealers who provide the Portfolio's,  Adviser's,  Sub-Adviser's or Secondary
Sub-Adviser's  other  clients  with  research,   analysis,  advice  and  similar
services.  The Secondary  Sub-Adviser may pay to brokers and dealers,  in return
for such research and analysis services,  a higher commission or spread than may
be charged by other brokers and dealers,  subject to the  Secondary  Sub-Adviser
determining in good faith that such  commission or spread is reasonable in terms
either of the  particular  transaction or of the overall  responsibility  of the
Secondary  Sub-Adviser to the Portfolio and its other clients and that the total
commissions  or spreads paid by the Portfolio  will be reasonable in relation to
the benefits to the Portfolio  over the long term. In no instance will Portfolio
securities  be  purchased  from  or sold to the  Secondary  Sub-Adviser,  or any
affiliated person thereof, except in accordance with the federal securities laws

purchase or sell the same  security on behalf of the  Portfolio  and one or more
other  accounts  advised  by the  Secondary  Sub-Adviser,  such  orders  will be
allocated as to price and amount among all such accounts in a manner believed to
be equitable to each account.  The Portfolio  recognizes that in some cases this
procedure may adversely affect the results  obtained for the Portfolio.  

      (c) The  Secondary  Sub-Adviser  will  maintain all books and records with
respect to the securities  transactions  of the Portfolio,  and will furnish the
Board,  Adviser,  and Sub-Adviser  with such periodic and special reports as the
Board,  Adviser,  or Sub-Adviser  reasonably may request. In compliance with the
requirements of Rule 31a-3 under the 1940 Act, the Secondary  Sub-Adviser hereby
agrees that all records which it maintains for the Portfolio are the property of
the Portfolio, agrees to preserve for the periods prescribed by Rule 31a-2 under
the 1940 Act any records  which it  maintains  for the  Portfolio  and which are
required to be maintained  by Rule 31a-1 under the 1940 Act, and further  agrees
to surrender  promptly to the  Portfolio  any records which it maintains for the
Portfolio  upon request by the  Portfolio.

      (d) The Secondary Sub-Adviser will provide the Board, the Adviser, and the
Sub-Adviser on a regular basis with economic and investment analyses and reports
and make available to the Board,  the Adviser,  and the Sub-Adviser upon request
any  economic,   statistical  and  investment  services  normally  available  to
institutional  or other  customers of the  Secondary  Sub-Adviser.  

      3.  DUTIES AS SUB-SUB-ADMINISTRATOR. Secondary Sub-Adviser will administer
the affairs of the Portfolio subject to the supervision of the Portfolio's Board
of  Trustees  ("Board"),  the  Adviser,  the  Sub-Adviser,   and  the  following
understandings:

      (a) Secondary  Sub-Adviser will supervise all aspects of the operations of
the Portfolio, including the oversight of transfer agency and custodial services
except  as  hereinafter  set  forth;  provided,  however,  that  nothing  herein
contained shall be deemed to relieve or deprive the Board of its  responsibility
for  control of the conduct of the affairs of the  Portfolio.  

      (b) At Secondary Sub-Adviser's expense, Secondary Sub-Adviser will provide
the  Portfolio  with  such  corporate,  administrative  and  clerical  personnel
(including  officers of the  Portfolio)  and services as are  reasonably  deemed
necessary or advisable by the Board. 

<PAGE>

      (c) Secondary  Sub-Adviser  will  arrange,  but not pay, for the periodic
preparation,   updating,   filing  and  dissemination  (as  applicable)  of  the
Portfolio's prospectus, proxy material, tax returns and required reports with or

other  appropriate  federal  or  state  regulatory  authorities.  

      (d) Secondary  Sub-Adviser  will provide the Portfolio with, or obtain for
it,  adequate  office space and all  necessary  office  equipment  and services,
including telephone service,  heat,  utilities,  stationery supplies and similar
items.  

      4.  FURTHER  DUTIES.  In all matters  relating to the  performance of this
Contract,  Secondary  Sub-Adviser  will act in conformity with the Agreement and
Declaration of Trust,  By-Laws and  Registration  Statement of the Portfolio and
with the  instructions  and  directions  of the Board and will  comply  with the
requirements  of the 1940 Act, the rules  thereunder,  and all other  applicable
federal and state laws and regulations.

      5.  SERVICES  NOT   EXCLUSIVE.   The   services   furnished  by  Secondary
Sub-Adviser  hereunder are not to be deemed exclusive and Secondary  Sub-Adviser
shall be free to  furnish  similar  services  to others so long as its  services
under this Contract are not impaired  thereby.  Nothing in this  Contract  shall
limit or restrict  the right of any  director,  officer or employee of Secondary
Sub-Adviser, who may also be a Trustee, officer or employee of the Portfolio, to
engage in any other  business or to devote his or her time and attention in part
to the management or other aspects of any other  business,  whether of a similar
nature or a dissimilar nature.

                         AMENDMENT TO CUSTODIAN CONTRACT

      This Amendment to the Custodian Contract is made as of January 26, 1999 by
and between Floating Rate Portfolio (the "Fund") and State Street Bank and Trust
Company (the "Custodian"). Capitalized terms used in this Amendment without
definition shall have the respective meanings ascribed to such terms in the
Custodian Contract referred to below.

      WHEREAS, the Fund and the Custodian entered into a Custodian Contract
dated as of April 30, 1997 (as amended and in effect from time to time, the
"Contract"); and

      WHEREAS, the Fund and the Custodian desire to amend certain provisions of
the Contract to reflect revisions to Rule 17f-5 ("Rule 17f-5") promulgated under
Section 17(f) of the Investment Company Act of 1940, as amended (the "1940
Act"); and

      WHEREAS, the Fund and the Custodian desire to amend and restate certain
other provisions of the Contract relating to the terms and conditions of the
custody of assets of the Fund held outside of the United States.

      NOW THEREFORE, in consideration of the foregoing and the mutual covenants
and agreements hereinafter contained, the parties hereby agree to amend the
Contract; pursuant to the terms thereof, as follows:

I.    Article 3 of the Contract is hereby deleted, and Articles 4 through 17 of
      the Contract are hereby amended, as of the effective date of this
      Amendment, by renumbering same as Articles 5 through 18, respectively.

II.   New Articles 3 and 4 of the Contract are hereby added, as of the effective
      date of this Amendment, as set forth below.

3.    THE CUSTODIAN AS FOREIGN CUSTODY MANAGER. 

3.1.  DEFINITIONS.

Capitalized terms in this Article 3 of the Contract shall have the following
meanings:

"Country Risk" means all factors reasonably related to the systemic risk of
holding Foreign Assets in a particular country including, but not limited to,
such country's political environment; economic and financial infrastructure
(including any Mandatory Securities Depositories operating in the country);
prevailing or developing custody and settlement practices; laws and regulations
applicable to the safekeeping and recovery of Foreign Assets held in custody in
that country; and factors comprising the "prevailing country risk", including
the effects of foreign law on the safekeeping of Fund assets, the likelihood of
expropriation, nationalization, freezing, or confiscation of the Fund's assets
and any reasonably foreseeable difficulties in repatriating the Fund's assets.

"Eligible Foreign Custodian" has the meaning set forth in section (a)(1) of Rule
17f-5, including a majority-owned or indirect subsidiary of a U.S. Bank (as
defined in Rule 17f-5), a bank holding company meeting the requirements of an

<PAGE>

Eligible Foreign Custodian (as set forth in Rule 17f-5 or by other appropriate
action of the SEC), or a foreign branch of a Bank (as defined in Section 2(a)(5)
of the 1940 Act) meeting the requirements of a custodian under Section 17(f) of
the 1940 Act, except that the term does not include Mandatory Securities
Depositories.

"Foreign Assets" means any of the Fund's investments (including foreign
currencies) for which the primary market is outside the United States, currency
contracts that are settled outside the United States and such cash and cash
equivalents as are reasonably necessary to effect the Fund's transactions in
such investments.

"Foreign Custody Manager" has the meaning set forth in section (a)(2) of Rule
17f-5.

"Mandatory Securities Depository" means a foreign securities depository or
clearing agency that, either as a legal or practical matter, must be used if the
Fund determines to place Foreign Assets in a country outside the United States
(i) because required by law or regulation; (ii) because securities cannot be
withdrawn from such foreign securities depository or clearing agency; or (iii)
because maintaining or effecting trades in securities outside the foreign
securities depository or clearing agency is not consistent with prevailing or
developing custodial or market practices.

3.2.  DELEGATION TO THE CUSTODIAN AS FOREIGN CUSTODY MANAGER.

The Fund, by resolution adopted by its Board of Trustees (the "Board"), hereby
delegates to the Custodian, subject to Section (b) of Rule 17f-5, the
responsibilities set forth in this Article 3 with respect to Foreign Assets held
outside the United States, and the Custodian hereby accepts such delegation as
Foreign Custody Manager of the Fund.

3.3.  COUNTRIES COVERED.

The Foreign Custody Manager shall be responsible for performing the delegated
responsibilities defined below only with respect to (a) the countries listed on
Schedule A hereto as approved by the Board, which list of Board-approved
countries may be amended from time to time by the Fund with the agreement of the
Foreign Custody Manager, and (b) the custody arrangements set forth on such
Schedule A. The Foreign Custody Manager shall list on Schedule A the Eligible
Foreign Custodians selected by the Foreign Custody Manager to maintain the
Fund's assets, which list of Eligible Foreign Custodians may be amended from
time to time in the sole discretion of the Foreign Custody Manager. Mandatory
Securities Depositories are listed on Schedule B to this Contract, which
Schedule B may be amended from time to time by the Foreign Custody Manager. The
Foreign Custody Manager will provide amended versions of Schedules A and B in
accordance with Section 3.7 of this Article 3.

Upon the receipt by the Foreign Custody Manager of Proper Instructions to open
an account or to place or maintain Foreign Assets in a country listed on
Schedule A, and the fulfillment by the Fund of the account opening requirements
for such country (if any), the Foreign Custody Manager shall be deemed to have
been appointed by the Board as Foreign Custody Manager with respect to that
country and to have accepted the delegation. Execution of this Amendment by the
Fund shall be deemed to be a Proper Instruction to open an account, or to place
or maintain Foreign Assets, in each Board-approved country listed on Schedule A


                                      2
<PAGE>

in which the Custodian has previously placed or currently maintains Foreign
Assets pursuant to the terms of the Contract. Following the receipt of Proper
Instructions directing the Foreign Custody Manager to close the account of the
Fund with the Eligible Foreign Custodian selected by the Foreign Custody Manager
in a designated country, the delegation by the Board to the Custodian as Foreign
Custody Manager for that country shall be deemed to have been withdrawn and the
Custodian shall immediately cease to be the Foreign Custody Manager of the Fund
with respect to that country.

The Foreign Custody Manager may withdraw its acceptance of delegated
responsibilities with respect to a designated country upon written notice to the
Fund. Thirty days (or such longer period as to which the parties agree in
writing) after receipt of any such notice by the Fund, the Custodian shall have
no further responsibility as Foreign Custody Manager to the Fund with respect to
the country as to which the Custodian's acceptance of delegation is withdrawn.

3.4.  SCOPE OF DELEGATED RESPONSIBILITIES.

      3.4.1.      SELECTION OF ELIGIBLE FOREIGN CUSTODIANS.

Subject to the provisions of this Article 3, the Foreign Custody Manager of the
Fund may place and maintain the Foreign Assets in the care of the Eligible
Foreign Custodians selected by the Foreign Custody Manager in each country
listed as "approved" on Schedule A, as such Schedule is amended from time to
time.

In performing its delegated responsibilities as Foreign Custody Manager to place
or maintain the Foreign Assets with an Eligible Foreign Custodian, the Foreign
Custody Manager shall determine that the Foreign Assets will be subject to
reasonable care, based on the standards applicable to custodians in the country
in which the Foreign Assets will be held by that Eligible Foreign Custodian,
after considering all factors relevant to the safekeeping of such assets,
including, without limitation, the factors specified in Rule 17f-5(c)(1).

      3.4.2.      CONTRACTS WITH ELIGIBLE FOREIGN CUSTODIANS.

The Foreign Custody Manager shall determine that the contract (or the rules or
established practices or procedures in the case of an Eligible Foreign Custodian
that is a foreign securities depository or clearing agency) governing the
foreign custody arrangements with each Eligible Foreign Custodian selected by
the Foreign Custody Manager will satisfy the requirements of Rule l7f-5(c)(2).

      3.4.3.      MONITORING.

In each case in which the Foreign Custody Manager maintains Foreign Assets with
an Eligible Foreign Custodian, selected by the Foreign Custody Manager, the
Foreign Custody Manager shall maintain a system to monitor (i) the
appropriateness of maintaining the Foreign Assets with such Eligible Foreign
Custodian, and (ii) the contract governing the custody arrangements established
by the Foreign Custody Manager with the Eligible Foreign Custodian (or the rules
or established practices and procedures in the case of an Eligible Foreign


                                       3
<PAGE>

Custodian selected by the Foreign Custody Manager which is a foreign securities
depository or clearing agency that is not a Mandatory Securities Depository).
The Foreign Custody Manager shall provide the Board with information at least
annually as to the factors used in such monitoring system. In the event the
Foreign Custody Manager determines that the custody arrangements with an
Eligible Foreign Custodian that it has selected are no longer appropriate, the
Foreign Custody Manager shall promptly transfer the Fund's Foreign Assets to
another Eligible Foreign Custodian in the market and shall notify the Board in
accordance with Section 3.7 hereunder.

3.5.  GUIDELINES FOR THE EXERCISE OF DELEGATED AUTHORITY.

For purposes of this Article 3, the Board shall be deemed to have considered and
determined to accept such Country Risk as is incurred by placing and maintaining
the Foreign Assets in each country for which the Custodian is serving as Foreign
Custody Manager of the Fund, and the Board shall be deemed to be monitoring on a
continuing basis such Country Risk to the extent that the Board considers
necessary or appropriate.

Notwithstanding any provision of this Contract to the contrary, the Fund and the
Custodian expressly acknowledge and agree that the Foreign Custody Manager,
shall not be delegated any responsibilities under this Article 3 with respect to
Mandatory Securities Depositories, and that the determination by or on behalf of
the Board to place the Foreign Assets in a particular country shall be deemed to
include the determination to place such Foreign Assets eligible for any
Mandatory Securities Depository with such Mandatory Securities Depository,
whether the Mandatory Securities Depository exists at the time the Foreign
Assets are acquired, or after the acquisition thereof.

3.6.  STANDARD OF CARE AS FOREIGN CUSTODY MANAGER OF THE FUND.

In performing the responsibilities delegated to it, the Foreign Custody Manager
shall exercise reasonable care, prudence and diligence such as a person having
responsibility for the safekeeping of assets of management investment companies
registered under the 1940 Act would exercise.

3.7.  REPORTING REQUIREMENTS.

The Foreign Custody Manager shall report at least quarterly on the Foreign
Assets held with each Eligible Foreign Custodian and, in connection therewith if
applicable, provide to the Board amended Schedules A or B at the end of the
calendar quarter in which an amendment to either Schedule has occurred. The
Foreign Custody Manager will make written reports notifying the Board of any
other material change in the foreign custody arrangements of the Fund defined in
this Article 3 promptly after the occurrence of the material change.

3.8. REPRESENTATIONS WITH RESPECT TO RULE 17F-5.

The Foreign Custody Manager represents to the Fund that it is a U.S. Bank as
defined in section (a)(7) of Rule 17f-5.



                                       4
<PAGE>

The Fund represents to the Custodian that the Board has determined that it is
reasonable for the Board to rely on the Custodian to perform the
responsibilities delegated pursuant to this Contract to the Custodian as the
Foreign Custody Manager of the Fund. 

3.9. EFFECTIVE DATE AND TERMINATION OF THE CUSTODIAN AS FOREIGN CUSTODY MANAGER.

The Board's delegation to the Custodian as Foreign Custody Manager of the Fund
shall be effective as of the date hereof and shall remain in effect until
terminated at any time, without penalty, by written notice from the terminating
party to the non-terminating party. Termination will become effective thirty
days after receipt by the non-terminating party of such notice. The provisions
of Section 3.3 hereof shall govern the delegation to and termination of the
Custodian as Foreign Custody Manager of the Fund with respect to designated
countries.

3.10. FUTURE NEGOTIATIONS.

If at any time prior to termination of this Amendment the Custodian as a matter
of standard business practice, accepts delegation as Foreign Custody Manager for
its U.S. mutual fund clients on terms materially different than set forth in
this Amendment, the Custodian hereby agrees to negotiate with the fund in good
faith with respect thereto.

4.    DUTIES OF THE CUSTODIAN WITH RESPECT TO PROPERTY OF THE FUND HELD OUTSIDE
      THE UNITED STATES.

Fund, with any Foreign Sub-Custodian in an account that is identified as
belonging to the Custodian for the benefit of its customers, PROVIDED HOWEVER,
that (i) the records of the Custodian with respect to foreign securities of the
Fund which are maintained in such account shall identify those securities as
belonging to the Fund and (ii), to the extent permitted and customary in the

             foreign securities are held or traded, including, without
             limitation: (A) delivering money to the seller thereof or to a

             or (B) in the case of a purchase effected through a Foreign

             Contract, legal fees, accounting fees, and other operating

             amount of such payment, setting forth the purpose for which such
             payment is to be made, declaring such purpose to be a proper
             purpose, and naming the person or persons to whom such payment is
             to be made.

      4.4.3.      MARKET CONDITIONS; MARKET INFORMATION.

Notwithstanding any provision of this Contract to the contrary, settlement and
payment for Foreign Assets received for the account of the Fund and delivery of
Foreign Assets maintained for the account of the Fund may be effected in
accordance with the customary established securities trading or processing
practices and procedures in the country or market in which the transaction
occurs generally accepted by Institutional Clients, including, without
limitation, delivering Foreign Assets to the purchaser thereof or to a dealer
therefor (or an agent for such purchaser or dealer) against a receipt with the
expectation of receiving later payment for such Foreign Assets from such
purchaser or dealer. For purposes of this Contract, "Institutional Clients"
means U.S. registered investment companies or major U.S. based commercial banks,
insurance companies, pension funds or substantially similar institutions which,
as a part of their ordinary business operations, purchase or sell securities and
make use of global custody services.

The Custodian shall provide to the Board the information with respect to custody
and settlement practices in countries in which the Custodian employs a Foreign
Sub-Custodian, including without limitation information relating to Foreign
Securities Systems, described on Schedule C hereto at the time or times set
forth on such Schedule. The Custodian may revise Schedule C from time to time,
provided that no such revision shall result in the Board being provided with
substantively less information than had been previously provided hereunder and,
provided further, that the Custodian shall in any event provide to the Board and
to A I M Advisors, Inc. annually the following information and opinions with
respect to the Board-approved countries listed on Schedule A:

      (i)    legal opinions relating to whether local law restricts with respect
             to U.S. registered mutual funds (a) access of a fund's independent


                                       8
<PAGE>

             public accountants to books and records of a Foreign Sub-Custodian
             or Foreign Securities System, (b) a fund's ability to recover in
             the event of bankruptcy or insolvency of a Foreign Sub-Custodian or
             Foreign Securities System, (c) a fund's ability to recover in the
             event of a loss by a Foreign Sub-Custodian or Foreign Securities
             System, and (d) the ability of a foreign investor to convert cash
             and cash equivalents to U.S. dollars;

      (ii)   summary of information regarding Foreign Securities Systems; and

      (iii)  country profile information containing market practice for (a)
             delivery versus payment, (b) settlement method, (c) currency
             restrictions, (d) buy- in practices, (e) foreign ownership limits,
             and (f) unique market arrangements.

4.5.  REGISTRATION OF FOREIGN SECURITIES.

The foreign securities maintained in the custody of a Foreign Custodian (other
than bearer securities) shall be registered in the name of the Fund or in the
name of the Custodian or in the name of any Foreign Sub-Custodian or in the name
of any nominee of the foregoing, and the Fund agrees to hold any such nominee
harmless from any liability as a holder of record of such foreign securities,
except to the extent that the Fund incurs loss or damage due to failure of such
nominee to meet its standard of care as set forth in the Contract. The Custodian
or a Foreign Sub-Custodian shall not be obligated to accept securities on behalf
of the Fund under the terms of this Contract unless the form of such securities
and the manner in which they are delivered are in accordance with reasonable
market practice.

4.6.  BANK ACCOUNTS.

The Custodian shall identify on its books as belonging to the Fund cash
(including cash denominated in foreign currencies) deposited with the Custodian.
Where the Custodian is unable to maintain, or market practice does not
facilitate the maintenance of, cash on the books of the Custodian, a bank
account or bank accounts opened and maintained outside the United States on
behalf of the Fund in a Foreign Sub-Custodian shall be subject only to draft or
order by the Custodian or such Foreign Sub-Custodian, acting pursuant to the
terms of this Contract to hold cash received by or from or for the account of
the Fund.

4.7.  COLLECTION OF INCOME.

The Custodian shall use reasonable commercial efforts to collect all dividends,
income and other payments with respect to the Foreign Assets held hereunder to
which the Fund shall be entitled and shall credit such income, as collected, to
the Fund. In the event the Custodian or a Foreign Sub-Custodian must use
measures beyond those which are customary in a particular country to collect
such payments, the Fund and the Custodian shall consult as to such measures and
as to the compensation and expenses of the Custodian attendant thereto.



                                       9
<PAGE>

4.8.  SHAREHOLDER RIGHTS.

With respect to the foreign securities held under this Article 4, the Custodian
will use commercially reasonable efforts to facilitate the exercise by the Fund
of voting and other shareholder rights, subject always to the laws, regulations
and practical constraints that may obtain in the country where such securities
are issued. The Fund acknowledges that local conditions, including lack of
regulation, onerous procedural obligations, lack of notice and other factors may
have the effect of severely limiting the ability of the Fund to exercise
shareholder rights.

4.9.  COMMUNICATIONS RELATING TO FOREIGN SECURITIES.

The Custodian shall transmit promptly to the Fund written information
(including, without limitation, pendency of calls and maturities of foreign
securities and expirations of rights in connection therewith) received by the
Custodian via the Foreign Sub-Custodians from issuers of the foreign securities
being held for the account of the Fund. With respect to tender or exchange
offers, the Custodian shall transmit promptly to the Fund written information so
received by the Custodian from issuers of the foreign securities whose tender or
exchange is sought or from the party (or its agents) making the tender or
exchange offer. Subject to the standard of care to which the Custodian is held
under this Contract, the Custodian shall not be liable for any untimely exercise
of any tender, exchange or other right or power in connection with foreign
securities or other property of the Fund at any time held by it unless (i) the
Custodian or the respective Foreign Sub-Custodian is in actual possession of
such foreign securities or property and (ii) the Custodian receives Proper
Instructions with regard to the exercise of any such right or power, and both
(i) and (ii) occur at least two New York business days prior to the date on
which the Custodian is to take action to exercise such right or power.

4.10. LIABILITY OF FOREIGN SUB-CUSTODIANS AND FOREIGN SECURITIES SYSTEMS.

Each agreement pursuant to which the Custodian employs a Foreign Sub-Custodian
shall, to the extent possible consistent with prevailing market practice,
require the Foreign Sub-Custodian to exercise reasonable care in the performance
of its duties and to indemnify, and hold harmless, the Custodian from and
against any loss, damage, cost, expense, liability or claim arising out of or in
connection with such Foreign Sub-Custodian's performance of such obligations. At
the election of the Fund, the Fund shall be entitled to be subrogated to the
rights of the Custodian with respect to any claims against a Foreign
Sub-Custodian as a consequence of any such loss, damage, cost, expense,
liability or claim if and to the extent that the Fund has not been made whole
for any such loss, damage, cost, expense, liability or claim.

4.11. TAX LAW.

The Custodian shall have no responsibility or liability for any obligations now
or hereafter imposed on the Fund or the Custodian as custodian of the Fund by
the tax law of the United States or of any state or political subdivision
thereof. With respect to jurisdictions other than the United States, the sole
responsibility of the Custodian with regard to the tax law of any such
jurisdiction shall be to use reasonable efforts to (a) notify the Fund of the
obligations imposed on the Fund or the Custodian as custodian of the Fund by the


                                       10
<PAGE>

tax law of such jurisdictions, including responsibility for withholding and
other taxes, assessment or other governmental charges, certifications and
government reporting and (b) perform such ministerial steps as are required to
collect any tax refund, to ascertain the appropriate rate of tax withholding and
to provide such documents as may be required to enable each Fund to receive
appropriate tax treatment under applicable tax laws and any applicable treaty
provisions. The Custodian, in performance of its duties under this Section,
shall be entitled to treat each Fund as a Delaware business trust which is
"registered investment company" under the laws of the United States, and it
shall be the duty of each Fund to inform the Custodian of any change in the
organization, domicile or, to the extent within the knowledge of the Fund, other
relevant facts concerning tax treatment of the Fund and further to inform the
Custodian if the Fund is or becomes the beneficiary of any special ruling or
treatment not applicable to the general nationality and category of entity of
which the Fund is a part under general laws and treaty provisions. The Custodian
shall be entitled to rely on any information supplied by the Fund. The Custodian
may engage reasonable professional advisors disclosed to the Fund by the
Custodian, which may include attorneys, accountants or financial institutions in
the regular business of investment administration and may rely upon advice
received therefrom.

4.12. LIABILITY OF CUSTODIAN.

Except as may arise from the Custodian's own negligence or willful misconduct or
the negligence or willful misconduct of a Sub-Custodian, the Custodian shall be
without liability to the Fund for any loss, liability, claim or expense
resulting from or caused by Country Risk (as such term is defined in Article 3
hereof), regardless of whether assets are maintained in the custody of a Foreign
Sub-Custodian or a Foreign Securities Depository, the Custodian shall be without
liability for any loss, damage, cost, expense, liability or claim resulting from
nationalization, expropriation, currency restrictions, or acts of war or
terrorism, or any other similar loss beyond the reasonable control of the
Custodian or the Sub-Custodian.

The Custodian shall be liable to the Fund on account of any actions or omissions
of any Foreign Sub-Custodian to the same extent as such Foreign Sub-Custodian
shall be liable to the Custodian.

4.13. USE OF TERM "FUND"; ASSETS AND LIABILITIES

All references in this Article 4 or in Article 3 of this Agreement to "Fund"
shall mean the Fund, or a Portfolio of the Fund, as the context requires or as
applicable.

The Custodian shall maintain separate and distinct records for each Portfolio
and the assets allocated solely with such Portfolio shall be held and accounted
for separately from the assets of the Fund associated solely with any other
Portfolio. The debts, liabilities, obligations and expenses incurred, contracted
for or otherwise existing with respect to a particular Portfolio shall be
enforceable against the assets of such Portfolio only, and not against the
assets of the Fund generally or the assets of any other Portfolio.

III.  Except as specifically superseded or modified herein, the terms and
      provisions of the Contract shall continue to apply with full force and
      effect. In the event of any conflict between the terms of the Contract


                                       11
<PAGE>

      prior to this Amendment and this Amendment, the terms of this Amendment
      shall prevail. If the Custodian is delegated the responsibilities of
      Foreign Custody Manager pursuant to the terms of Article 3 hereof, in the
      event of any conflict between the provisions of Articles 3 and 4 hereof,
      the provisions of Article 3 shall prevail.

      IN WITNESS WHEREOF, each of the parties has caused this Amendment to be
executed in its name and behalf by its duly authorized representative as of the
date first above written.

                  (c) without limiting the generality of the foregoing,
            Chancellor LGT shall not, in connection with Chancellor LGT's duties

<PAGE>

                  authority of any Oral or Written Instruction, notice or other
                  instrument which conforms to the applicable requirements of
                  this Agreement, if any and that Chancellor LGT reasonably

Notwithstanding any other provisions of this Agreement, the following provisions
shall apply with respect to Chancellor LGT's computation of the Fund's and the
Portfolio's net asset value: Chancellor LGT shall be held to the exercise of
reasonable care in computing and determining net asset value as provided in
Section 4(a), above, but shall not be held accountable or liable for any losses,
damages or expenses of the Fund, the Portfolio or any Shareholder or former
Shareholder may incur arising from or based upon errors or delays in the
determination of such net asset value unless such error or delay was due to
Chancellor LGT's negligence or willful misfeasance in the computation and
determination of such net asset value. The parties hereto acknowledge, however,
that Chancellor LGT causing an error or delay in the determination of net asset
value may, but does not in an of itself, constitute negligence or willful
misfeasance. In no event shall Chancellor LGT be liable or responsible to the
Fund or the Portfolio or any other party for any error or delay which continued
or was undetected after the date of an audit of the Fund or the Portfolio
performed by the certified public accountants employed by the Fund or the
Portfolio if, in the exercise of reasonable care in accordance with generally
accepted accounting principles, such accountants should have become aware of
such error or delay in the course of performing such audit. Chancellor LGT's
liability for any such negligence or willful misfeasance which results in an
error in determination of such net asset value be limited to the direct
out-of-pocket loss the Fund, the Portfolio and/or any Shareholder or former
Shareholder shall actually incur.

            Without limiting the generality of the foregoing, Chancellor LGT
shall not be held accountable or liable to the Fund, the Portfolio, a
Shareholder or former Shareholder or any other person for any delays or losses,
damages or expenses any of them may suffer or incur resulting from (1)
Chancellor LGT's failure to receive timely and suitable notification concerning
quotations, corporate actions or similar matters relating to or affecting
portfolio securities of the Fund or the Portfolio or (2) any errors in the
computation of a net asset value based upon or arising out of quotations or
information as to corporate actions if received by Chancellor LGT from a source
that Chancellor LGT was authorized to rely upon. Nevertheless, Chancellor LGT
will use its best judgment in determining whether to verify through other
sources any information that it has received as to quotations or corporate
actions if Chancellor LGT has reason to believe that any such information is
incorrect.

<PAGE>

            SECTION 10. RECEIPT OF ADVICE. If Chancellor LGT is in doubt as to
any action to be taken or omitted by it, Chancellor LGT may request, and shall
be entitled to rely upon, directions and advice from the Fund or the Portfolio,
including Oral or Written Instructions where appropriate, or from counsel of its
own choosing (who may also be counsel for the Fund or the Portfolio), with
respect to any question of law. In case of conflict between directions, advice
or Oral and Written Instructions received by Chancellor LGT pursuant to this
Section, Chancellor LGT shall be entitled to rely on and follow the advice
received from counsel as described above. Chancellor LGT shall be protected in
any action or in action that it takes in reliance on any directions, advice or
Oral or Written Instructions received pursuant to this Section that Chancellor
LGT, after the receipt of the same, in good faith believes to be consistent with
such directions, advice or Oral or Written Instructions, as the case may be.
Notwithstanding the foregoing, nothing in this Section shall be construed as
imposing on Chancellor LGT any obligation to seek such directions, advice or
Oral or Written Instruction, or to act in accordance with them when received,
unless the same is a condition to Chancellor LGT's properly taking or omitting
to take such action under the terms of this Agreement.

            SECTION 11. INDEMNIFICATION OF CHANCELLOR LGT. The Fund and the
Portfolio agree, separately and not jointly, to indemnify and hold harmless
Chancellor LGT and its officers, directors, employees, nominees and
subcontractors, if any, from all taxes, charges, expenses, assessments, claims
and liabilities, including, without limitation, liabilities arising under the
1940 Act, the Securities Act of 1933, as amended, the Securities Exchange Act of
1934, as amended, the Commodities Exchange Act and any state or foreign

reasonable attorneys' fees and disbursements, arising directly or indirectly
from any action or thing that Chancellor LGT takes or omits to take or do:

Portfolio and Chancellor LGT.

            SECTION 18.  COUNTERPARTS.  This Agreement may be executed in two
or more counterparts, each of which shall be deemed an original, but all of
which together constitute one and the same instrument.
