                          SUPPLEMENTAL PROXY STATEMENT
                                 April 10, 2001

This Supplemental Proxy Statement is furnished in connection with a solicitation
of proxies  made by, and on behalf of, the Board of Trustees  of INVESCO  Global
Health  Sciences Fund ("Global  Health  Sciences Fund") to be used at the Annual
Meeting of Shareholders of the Global Health  Sciences Fund  ("Meeting"),  to be
held on May 8, 2001 at 1:00 p.m.  at 7800 East Union  Avenue,  Denver,  Colorado
80237, the principal executive offices of Global Health Sciences Fund.

On March 19,  2001, a Proxy  Statement  (the "Proxy  Statement"),  was mailed to
shareholders  of record as of March 9, 2001. This  Supplemental  Proxy Statement
sets forth a  modification  that  substantively  changes one of the terms of the
proposed  reorganization  of the Global Health  Sciences  Fund  described in the
Proxy Statement, and is incorporated therein by reference. The Board of Trustees
requests  that  shareholders  carefully  consider  this  modification,  and  all
information  contained in the Proxy  Statement,  in  determining  their vote. IN
LIGHT OF THE  MODIFICATION  SET  FORTH  IN THIS  SUPPLEMENTAL  PROXY  STATEMENT,
SHAREHOLDERS  THAT HAVE  ALREADY  VOTED THEIR  SHARES ON PROPOSALS 1 AND 2 TO BE
CONSIDERED  AT THE MEETING  CAN EITHER  RE-VOTE  THEIR  SHARES ON THE PROXY CARD
ENCLOSED HEREWITH,  OR DISREGARD THE PROXY CARD ENCLOSED HEREWITH AND HAVE THEIR
SHARES VOTED AS  INDICATED ON THEIR  ORIGINAL  PROXY CARD.  UNLESS  SHAREHOLDERS
SUBMIT A NEW PROXY CARD,  SHARES VOTED ON THE ORIGINAL PROXY CARD DELIVERED WITH
THE PROXY  STATEMENT WILL BE COUNTED IN DETERMINING  THE PROPOSALS  CONTAINED IN
THE PROXY  STATEMENT AND COUNTED IN DETERMINING  WHETHER A QUORUM IS REPRESENTED
AT THE  MEETING.  IF YOU HAVE NOT  ALREADY  VOTED YOUR  SHARES ON THE PROXY CARD
ENCLOSED  WITH THE PROXY  STATEMENT,  THE BOARD OF  TRUSTEES  REQUESTS  THAT YOU
CONSIDER THE MODIFICATION  SET FORTH IN THIS  SUPPLEMENTAL  PROXY STATEMENT,  AS
WELL AS THE INFORMATION  CONTAINED IN THE PROXY STATEMENT,  AND VOTE YOUR SHARES
ON THE PROXY CARD ENCLOSED HEREWITH.

PROPOSED  CONTINGENT DEFERRED SALES CHARGE TO BECOME A REDEMPTION FEE TO BE
RETAINED BY FUND

The Global  Health  Sciences  Fund's  Trustees  and INVESCO  Funds  Group,  Inc.
("INVESCO")  have  reconsidered the structure of the two percent (2%) Contingent
Deferred Sales Charge or "CDSC" referred to on pages 6, 11, 13, 17-22, and 29 of
the Proxy  Statement.  All references to  "Contingent  Deferred Sales Charge" or
"CDSC"  contained in the Proxy  Statement  are hereby  deleted and, as discussed
below,  replaced  with the term  "Redemption  Fee." As  described  in the  Proxy
Statement,  shareholders  of the Global  Health  Sciences  Fund,  upon  becoming
shareholders of the new open-end fund series of INVESCO  Counselor Series Funds,
Inc.  (the "New Fund"),  would have been  subject to a 2% CDSC if they  redeemed
their shares of the New Fund within twelve months.  This 2% CDSC would have been
retained by INVESCO in order to partially  offset increased  distribution  costs
that it expects to incur as a result of the proposed Reorganization.

It is now  proposed  that the  proceeds  from the 2% fee,  now  referred to as a
Redemption  Fee,  should be retained by the New Fund,  rather than INVESCO.  The
purposes of this  Redemption  Fee primarily  will be to  discourage  large scale
redemptions from the New Fund immediately  following the Reorganization,  and to

offset  potentially  increased New Fund operating  costs likely to result should
substantial  redemptions from the New Fund occur after the  Reorganization.  The
proposed  Redemption Fee will result in redeeming  shareholders  of the New Fund
bearing  at  least  a  portion  of  these  increased  Fund  operating  expenses.
Therefore,  with  this  modification  INVESCO  will be  giving  the New Fund the
opportunity to retain the proceeds from the Redemption Fee, should  shareholders
approve Proposal 2.

INVESCO  and the  Global  Health  Sciences  Fund's  Trustees  believe  that this
modification  to the terms of  Proposal 2 is clearly  in the best  interests  of
Global Health Sciences Fund shareholders because retention of the Redemption Fee
by the New Fund will serve as a direct financial benefit to the New Fund.

Shareholders  having  questions  concerning the proposed  Reorganization  should
contact INVESCO Funds Group, Inc. toll-free at 1(800) 528-8765.

             THE BOARD OF TRUSTEES UNANIMOUSLY RECOMMENDS A VOTE FOR
                      PROPOSALS 1 AND 2(A), 2(B) AND 2(C).
