             as supplemented December 4, 2003 and December 15, 2003

This supplement supercedes and replaces in its entirety the supplement dated
December 4, 2003.

Prior to November 25, 2003, INVESCO Funds Group, Inc. ("INVESCO") was the
investment advisor for your Fund. As of November 25, 2003, A I M Advisors, Inc.
("AIM") became the investment advisor for your Fund. Both INVESCO and AIM are
indirect wholly owned subsidiaries of AMVESCAP PLC.

On December 2, 2003 each of the Securities and Exchange Commission ("SEC") and
the Office of the Attorney General of the State of New York ("NYAG") filed civil
proceedings against INVESCO and Raymond R. Cunningham, in his capacity as the
chief executive officer of INVESCO. In addition, on December 2, 2003, the State
of Colorado filed civil proceedings against INVESCO. Neither your Fund nor any
other INVESCO Fund has been named as a defendant in any of these proceedings.

The SEC proceeding, filed in the United States District Court for the District
of Colorado [Civil Action No. 03-N-2421 (PAC)], alleges that INVESCO failed to
disclose in the INVESCO Funds' prospectuses and to the INVESCO Funds'
independent directors that INVESCO had entered into certain arrangements
permitting market timing of the INVESCO Funds. The SEC alleges violations of
Section 17(a) of the Securities Act of 1933, Section 10(b) of the Securities
Exchange Act of 1934 and Rule 10b-5 under that Act, Section 206(1) and 206(2) of
the Investment Advisers act of 1940, and Sections 34(b) and 36(a) of the
Investment Company Act of 1940. The SEC is seeking injunctions, including
permanent injunctions from serving as an investment advisor, officer or director
of an investment company; an accounting of all market timing as well as certain
fees and compensation received; disgorgement; civil monetary penalties; and
other relief.

The NYAG proceeding, filed in the Supreme Court of the State of New York (New
York County), is also based on the circumstances described above. The NYAG
proceeding alleges violation of Article 23-A (the "Martin Act") and Section 349
of the General Business Law of the State of New York and Section 63(12) of the
State of New York's Executive Law. The NYAG is seeking injunctions, including
permanent injunctions from directly or indirectly selling or distributing shares
of mutual funds; disgorgement of all profits obtained, including fees collected,
and payment of all




restitution and damages caused, directly or indirectly from the alleged illegal
activities; civil monetary penalties; and other relief.

The Colorado proceeding, filed in the Colorado District Court, in the City and
County of Denver, Colorado, is also based on the circumstances described above.
The Colorado proceeding alleges violations of Section 6-1-105(1) of the Colorado
Consumer Protection Act. The State of Colorado is seeking injunctions;
restitution, disgorgement and other equitable relief; civil monetary penalties;
and other relief.

No relief is being sought against your Fund or any of the INVESCO Funds in any
of these proceedings.

If INVESCO is unsuccessful in its defense of these proceedings, it could be
barred from serving as an investment advisor for any investment company
registered under the Investment Company Act of 1940, as amended (a "registered
investment company"). Similarly, if Mr. Cunningham is unsuccessful in his
defense of these proceedings, he could be barred from serving as an officer or
director of any registered investment company. Such results could also affect
the ability of AIM, or any other investment advisor directly or indirectly owned
by AMVESCAP, from serving as an investment advisor to any registered investment
company, including your Fund. Your Fund has been informed by AIM that, if either
of these results occur, AIM will seek exemptive relief from the SEC to permit it
to continue to serve as your Fund's investment advisor. There can be no
assurance that such exemptive relief will be granted.

In addition to the complaints described above, multiple lawsuits, including
class action and shareholder derivative suits, have been filed against certain
INVESCO Funds, AIM funds, INVESCO, AMVESCAP and certain related parties,
primarily based upon the allegations in the complaints described above. Such
lawsuits allege a variety of theories for recovery including, but not limited
to: (i) violation of various provisions of the Federal securities laws; (ii)
breach of fiduciary duty; and (iii) breach of contract. The lawsuits have been
filed in both Federal and state courts and seek such remedies as compensatory
damages; restitution; rescission; accounting for wrongfully gotten gains,
profits and compensation; injunctive relief; disgorgement; equitable relief;
interest and the payment of attorneys' and experts' fees. The following list
identifies such lawsuits that have been served as of the date of this
supplement:

         o        JERRY FATTAH, CUSTODIAN FOR BASIM FATTAH V. INVESCO ADVANTAGE
                  HEALTH SCIENCES FUND, ET AL., in the United States District
                  Court, District of Colorado (Civil Action Number 03-F-2456),
                  filed on December 4, 2003.

         o        JOEL GOODMAN V. INVESCO FUNDS GROUP, INC., ET AL., in the
                  District Court, City and County of Denver, Colorado (Case
                  Number 03CV9268), filed on December 5, 2003.

         o        L. SCOTT KARLIN, DERIVATIVELY ON BEHALF OF INVESCO FUNDS
                  GROUP, INC. V. AMVESCAP PLC, INVESCO, INC., ET AL., in the
                  United States District Court, District of Colorado (Civil
                  Action No. 03-MK-2406), filed on November 28, 2003.

         o        EDWARD LOWINGER AND SHARON LOWINGER V. INVESCO ADVANTAGE
                  HEALTH SCIENCES FUND, ET AL., in the United States District
                  Court, Southern District of New York (Civil Action No.
                  03-CV-9634), filed on December 4, 2003.

         o        RICHARD RAVER V. INVESCO FUNDS GROUP, INC., ET AL., in the
                  United States District Court, District of Colorado (Civil
                  Action No. 03-F-2441), filed on December 2, 2003.

More detailed information regarding each of the cases identified above is
provided in each fund's statement of additional information. Additional lawsuits
arising out of these circumstances and presenting similar allegations and
requests for relief may be filed against the funds, INVESCO, AMVESCAP and
related parties in the future. Information about any similar additional lawsuits
will be provided in the statement of additional information.

As a result of these developments, investors in the AIM and INVESCO Funds might
react by redeeming their investments. This might require the funds to sell
investments to provide for sufficient liquidity and could also have an adverse
effect on the investment performance of the funds.
