Dear Shareholder:

         As you may be aware, AMVESCAP PLC, the parent company of your Fund's
investment advisor, has undertaken an integration initiative for its North
American mutual fund operations. In the first phase of the integration
initiative, A I M Distributers, Inc. became the sole distributor for all INVESCO
Funds and is now distributor for all INVESCO Funds and the AIM Funds (including
your Fund).

         As a result of this integration initiative, the independent directors
of your Board of Directors believe that your interests would best be served if
the AIM Funds and the INVESCO Funds had a unified board of directors/trustees.
The attached proxy statement seeks your vote in favor of the persons nominated
to serve as directors.

         The integration initiative also calls for changing the organizational
structure of the AIM Funds and the INVESCO Funds. To accomplish this goal,
AMVESCAP PLC has recommended that all INVESCO Funds and AIM Funds organized as
Maryland corporations change their form and state of organization to Delaware
statutory trusts. Your Board has approved redomesticating your Fund as a series
of an existing Delaware statutory trust. The attached proxy statement seeks your
approval of this redomestication.

         Your vote is important. Please take a moment after reviewing the
enclosed materials to sign and return your proxy card in the enclosed postage
paid return envelope. If you attend the meeting, you may vote your shares in
person. If you expect to attend the meeting in person, or have questions, please
notify us by calling (800) 952-3502. If we do not hear from you after a
reasonable amount of time, you may receive a telephone call from our proxy
solicitor, Georgeson Shareholder Communications, Inc., reminding you to vote
your shares.

Sincerely,

/s/ Robert H. Graham

                        SPECIAL MEETINGS OF SHAREHOLDERS
                         TO BE HELD ON OCTOBER 21, 2003

                                  INTRODUCTION

         Proposals 1, 2 and 3 that you are being asked to vote on relate to or
result from an integration initiative announced on March 27, 2003, by AMVESCAP
PLC ("AMVESCAP"), the parent company of A I M Advisors, Inc. ("AIM") and INVESCO
Funds Group, Inc. ("INVESCO"), with respect to its North American mutual fund
operations. The primary components of AMVESCAP's integration initiative are:

         -        Using a single distributor for all AMVESCAP mutual funds in
                  the United States, with A I M Distributors, Inc. ("AIM
                  Distributors"), the distributor for the retail mutual funds
                  advised by AIM (the "AIM Funds"), replacing INVESCO
                  Distributors, Inc. as the distributor for the retail mutual
                  funds advised by INVESCO (the "INVESCO Funds") effective July
                  1, 2003.

         -        Integrating back office support and creating a single platform
                  for back office support of AMVESCAP's mutual fund operations
                  in the United States, including such support services as
                  transfer agency and information technology, with the result
                  that shares of the AIM Funds and shares of the INVESCO Funds
                  generally will be able to be exchanged for shares of the same
                  or a similar class of each other.

         -        Rationalizing and streamlining the various AIM Funds and
                  INVESCO Funds, thereby reducing the number of smaller and less
                  efficient funds that compete for limited shareholder assets
                  and consolidating certain funds having similar investment
                  objectives and strategies.

         -        Rationalizing the contractual arrangements for the provision
                  of investment advisory and administrative services to the AIM
                  Funds and the INVESCO Funds, with the objective of having AIM
                  become the investment advisor and administrator for each
                  INVESCO Fund.

         -        Simplifying the organizational structure of the AIM Funds and
                  the INVESCO Funds so that they are all organized as Delaware
                  statutory trusts, using as few



                  entities as practicable. Proposals 2 and 3 relate to this
                  component of AMVESCAP's integration initiative.

         In considering the integration initiative proposed by AMVESCAP, the
directors/trustees of the AIM Funds and the directors of the INVESCO Funds who
are not "interested persons" (as defined in the Investment Company Act of 1940
(the "1940 Act")) of the Funds or their advisors determined that the
shareholders of both the AIM Funds and the INVESCO Funds would benefit if one
set of directors/trustees was responsible for overseeing the operation of both
the AIM Funds and the INVESCO Funds and the services provided by AIM, INVESCO
and their affiliates. Accordingly, these directors/trustees agreed to combine
the separate boards and create a unified board of directors/trustees. Proposal 1
relates to the election of directors of your Fund.

                INFORMATION ABOUT THE SPECIAL MEETINGS AND VOTING

PROXY STATEMENT

         We are sending you this Proxy Statement and the enclosed proxy card on
behalf of the series portfolios of Short-Term Investments Co. and Tax-Free
Investments Co. (each a "Company," and together, the "Companies") listed above
(each a "Fund," and together, the "Funds") because the Boards of Directors of
the Companies (the "Boards") are soliciting your proxy to vote at the Special
Meetings of Shareholders and at any adjournments of the Special Meetings
(collectively, the "Special Meetings"). This Proxy Statement gives you
information about the business to be conducted at the Special Meetings. However,
you do not need to attend a Special Meeting to vote your shares. Instead, you
may simply complete, sign and return the enclosed proxy card.

         The Companies intend to mail this Proxy Statement, the enclosed Notice
of Special Meetings of Shareholders and the enclosed proxy card on or about
August 25, 2003 to all shareholders entitled to vote. Shareholders of record of
any class of a Fund as of the close of business on July 25, 2003 (the "Record
Date") are entitled to vote at the applicable Special Meeting. The number of
shares outstanding of each class of each Fund on the Record Date can be found in
Exhibit A. Each share of a Fund that you own entitles you to one vote on each
proposal set forth in the table below that applies to the Fund (a fractional
share has a fractional vote).

         We have previously sent to shareholders the most recent annual report
for their Fund, including financial statements, and the most recent semiannual
report succeeding the annual report, if any. If you have not received such
report(s) or would like to receive an additional copy, please contact A I M Fund
Services, Inc., P.O. Box 4739, Houston, Texas 77210-4739, or call (800)
347-4246. We will furnish such report(s) free of charge.

TIME AND PLACE OF SPECIAL MEETINGS

         We are holding the Special Meetings at 11 Greenway Plaza, Suite 100,
Houston, Texas 77046-1173 on October 21, 2003, at 3:00 p.m., Central Time.

VOTING IN PERSON

         If you do attend a Special Meeting and wish to vote in person, we will
provide you with a ballot prior to the vote. However, if your shares are held in
the name of your broker, bank or other nominee, you must bring a letter from the
nominee indicating that you are the beneficial owner of the shares on the Record
Date and authorizing you to vote. Please call the applicable Company at (800)
952-3502 if you plan to attend a Special Meeting.

VOTING BY PROXY

         Whether you plan to attend a Special Meeting or not, we urge you to
complete, sign and date the enclosed proxy card and to return it promptly in the
envelope provided. Returning the proxy card will not affect your right to attend
a Special Meeting and vote.

         If you properly fill in and sign your proxy card and send it to us in
time to vote at the Special Meetings, your "proxy" (the individual named on your
proxy card) will vote your shares as you have directed. If you sign your proxy
card but do not make specific choices, your proxy will vote your shares as
recommended by the Board of your Company as follows and in accordance with
management's recommendation on other matters:

         -        FOR the election of all 16 nominees for directors of your
                  Company.

         -        FOR the proposal to approve an Agreement and Plan of
                  Reorganization (the "STIC Plan") to redomesticate each series
                  portfolio of Short-Term Investments Co. as a new series
                  portfolio of an existing Delaware statutory trust.

         -        FOR the proposal to approve an Agreement and Plan of
                  Reorganization (the "TFIC Plan") to redomesticate Tax-Free
                  Investments Co. as a Delaware statutory trust.

                                       3



         Your proxy will have the authority to vote and act on your behalf at
any adjournment of the Special Meetings.

         If you authorize a proxy, you may revoke it at any time before it is
exercised by sending in another proxy card with a later date or by notifying the
applicable Company's Secretary in writing to the address of such Company set
forth on the cover page of this Proxy Statement before the Special Meetings that
you have revoked your proxy. In addition, although merely attending a Special
Meeting will not revoke your proxy, if you are present at a Special Meeting you
may withdraw your proxy and vote in person. Shareholders may also transact any
other business not currently contemplated that may properly come before the
Special Meetings in the discretion of the proxies or their substitutes.

QUORUM REQUIREMENT AND ADJOURNMENT

         A quorum of shareholders is necessary to hold a valid meeting. A quorum
will exist for Proposals 1, 2 and 3 for a particular Company if shareholders
entitled to vote one-third of the issued and outstanding shares of such Company
on the Record Date are present at the Special Meetings in person or by proxy.

         Under the rules applicable to broker-dealers, if your broker holds your
shares in its name, the broker will be entitled to vote your shares even if it
has not received instructions from you. A "broker non-vote" occurs when a broker
has not received voting instructions from a shareholder and is barred from
voting the shares without shareholder instructions because the proposal is
non-routine.

         Abstentions and broker non-votes will count as shares present at the
Special Meetings for purposes of establishing a quorum.

         If a quorum is not present at a Special Meeting or a quorum is present
but sufficient votes to approve a Proposal are not received, the persons named
as proxies may propose one or more adjournments of the Special Meeting to permit
further solicitation of proxies. Any such adjournment will require the
affirmative vote of a majority of those shares represented at the Special
Meeting in person or by proxy. The persons named as proxies will vote those
proxies that they are entitled to vote FOR a Proposal in favor of such an
adjournment and will vote those proxies required to be voted AGAINST such
Proposal against such an adjournment. A shareholder vote may be taken on a
Proposal in this Proxy Statement prior to any such adjournment if sufficient
votes have been received and it is otherwise appropriate.

VOTE NECESSARY TO APPROVE EACH PROPOSAL

         PROPOSAL 1. The affirmative vote of a plurality of votes cast by the
shareholders of a Company is necessary to elect directors of that Company at a
Special Meeting, meaning that the director nominee with the most affirmative
votes for a particular slot is elected for that slot. In an uncontested election
for directors, the plurality requirement is not a factor. Abstentions will not
count as votes cast and will have no effect on the outcome of this proposal. We
expect that brokers will be entitled to vote on this proposal, but any broker
non-vote will have no effect on the outcome of this proposal.

         PROPOSAL 2. Approval of Proposal 2 requires the affirmative vote of a
majority of the issued and outstanding shares of Short-Term Investments Co. at
its Special Meeting.

                                       4



Abstentions and broker non-votes are counted as present but are not considered
votes cast at the Special Meeting. As a result, they have the same effect as a
vote against the STIC Plan because approval of the STIC Plan requires the
affirmative vote of a percentage of the outstanding voting securities.

         PROPOSAL 3. Approval of Proposal 3 requires the affirmative vote of a
majority of the issued and outstanding shares of Tax-Free Investments Co. at its
Special Meeting. Abstentions and broker non-votes are counted as present but are
not considered votes cast at the Special Meeting. As a result, they have the
same effect as a vote against the TFIC Plan because approval of the TFIC Plan
requires the affirmative vote of a percentage of the outstanding voting
securities.

PROXY SOLICITATION

         The Companies have engaged the services of Georgeson Shareholder
Communications, Inc. ("Solicitor") to assist in the solicitation of proxies for
the Special Meetings. Solicitor's costs are estimated to be approximately
$11,049. The Companies expect to solicit proxies principally by mail, but the
Companies or Solicitor may also solicit proxies by telephone, facsimile or
personal interview. The Companies' officers will not receive any additional or
special compensation for any such solicitation. Each Fund will pay for its
proportionate share of the cost of soliciting proxies, the printing and mailing
of this Proxy Statement, the attached Notice of Special Meetings of
Shareholders, the enclosed proxy card, and any further solicitation.

OTHER MATTERS

         Management does not know of any matters to be presented at the Special
Meetings other than those discussed in this Proxy Statement. If any other
matters properly come before the Special Meetings, the shares represented by
proxies will be voted with respect thereto in accordance with management's
recommendation.

SHAREHOLDER PROPOSALS

         As a general matter, the Funds do not hold regular meetings of
shareholders. If you wish to submit a proposal for consideration at a meeting of
shareholders of your Fund, you should send such proposal to the applicable
Company at the address set forth on the first page of this Proxy Statement. To
be considered for presentation at a meeting of shareholders, the applicable
Company must receive proposals a reasonable time before proxy materials are
prepared for the meeting. Your proposal also must comply with applicable law.

         For a discussion of procedures that you must follow if you want to
propose an individual for nomination as a director, please refer to the section
of this Proxy Statement entitled "Proposal 1 - Committees of the Board -
Committee on Directors/Trustees."

                                  PROPOSAL 1 -
                              ELECTION OF DIRECTORS

WHICH FUNDS' SHAREHOLDERS WILL VOTE ON PROPOSAL 1?

         Proposal 1 applies to the shareholders of all Funds.

BACKGROUND

         In considering the integration initiative proposed by AMVESCAP, the
independent directors/trustees of the AIM Funds and the independent directors of
the INVESCO Funds determined that the shareholders of all the AIM Funds and the
INVESCO Funds would benefit if a unified board of directors/trustees was
responsible for overseeing the operation of both the AIM Funds and the INVESCO
Funds and the services provided by AIM, INVESCO and their affiliates.
Accordingly, the Boards of Directors/Trustees of the AIM Funds and the Boards of
Directors of the INVESCO Funds agreed to combine the separate boards and create
a unified board of directors/trustees.

STRUCTURE OF THE BOARD OF DIRECTORS

         Each Board currently consists of 12 persons. Ten of the current
directors are "independent," meaning they are not "interested persons" of the
Companies within the meaning of the 1940 Act. Two of the current directors are
"interested persons" because of their business and financial relationships with
the Companies and AIM, each Company's investment advisor, and/or AIM's parent,
AMVESCAP.

NOMINEES FOR DIRECTORS

         Each Company's Committee on Directors/Trustees (which consists solely
of independent directors) has approved the nomination of each of the 12 current
directors, as set forth below, to serve as director until his or her successor
is elected and qualified. In addition, each Company's Committee on
Directors/Trustees has approved the nomination of four new nominees, as set
forth below, to serve as director until his or her successor is elected and
qualified. These four new nominees were nominated to effect the proposed
combination of the Boards of Directors/Trustees of the AIM Funds and the Boards
of Directors of the INVESCO Funds.

         Each nominee who is a current director serves as a director or trustee
of the 17 registered investment companies comprising the AIM Funds. Each nominee
who is a current director oversees 86 portfolios that comprise the AIM Funds.
The business address of each nominee who is a current director is 11 Greenway
Plaza, Suite 100, Houston, Texas 77046-1173.

         Each new nominee serves as a director of ten registered investment
companies comprising the INVESCO Funds. Each new nominee currently oversees 46
portfolios which comprise the INVESCO Funds. The business address of each new
nominee is 4350 South Monaco Street, Denver, Colorado 80237.

         If elected, each nominee would oversee a total of 27 registered
investment companies currently comprising 132 portfolios.

DIRECTOR'S COMPENSATION

         Each director who is not affiliated with AIM is compensated for his or
her services according to a fee schedule which recognizes the fact that such
director also serves as a director or trustee of other AIM Funds. Each such
director receives a fee, allocated among the AIM Funds for which he or she
serves as a director or trustee, which consists of an annual retainer component
and a meeting fee component.

         Information regarding compensation paid or accrued for each director of
the Companies who was not affiliated with AIM during the year ended December 31,
2002 is found in Exhibit B.

RETIREMENT PLAN FOR DIRECTORS

         The directors have adopted a retirement plan for the directors of the
Companies who are not affiliated with AIM. The retirement plan includes a
retirement policy as well as retirement benefits for the non-AIM-affiliated
directors.

         The retirement policy permits each non-AIM-affiliated directors to
serve until December 31 of the year in which the director turns 72. A majority
of the directors may extend from time to time the retirement date of a director.

         Annual retirement benefits are available to each non-AIM-affiliated
director of the Companies and/or the other AIM Funds (each, a "Covered Fund")
who has at least five years of credited service as a director (including service
to a predecessor fund) for a Covered Fund. The retirement benefits will equal
75% of the director's annual retainer paid or accrued by any Covered Fund to
such director during the twelve-month period prior to retirement, including the

                                       13



amount of any retainer deferred under a separate deferred compensation agreement
between the Covered Fund and the director. The annual retirement benefits are
payable in quarterly installments for a number of years equal to the lesser of
(i) ten or (ii) the number of such director's credited years of service. A death
benefit is also available under the plan that provides a surviving spouse with a
quarterly installment of 50% of a deceased director's retirement benefits for
the same length of time that the director would have received the benefits based
on his or her service. A director must have attained the age of 65 (55 in the
event of death or disability) to receive any retirement benefit. Payment of
benefits under the plan is not secured or funded by the Companies.

DEFERRED COMPENSATION AGREEMENTS

         Messrs. Dunn, Fields, Frischling and Sklar and Dr. Mathai-Davis (the
"Deferring Directors") have each executed a Deferred Compensation Agreement
(collectively, the "Compensation Agreements"). Pursuant to the Compensation
Agreements, the Deferring Directors have the option to elect to defer receipt of
up to 100% of their compensation payable by the Companies, and such amounts are
placed into a deferral account. Currently, the Deferring Directors have the
option to select various AIM Funds in which all or part of their deferral
accounts shall be deemed to be invested. Distributions from the Deferring
Directors' deferral accounts will be paid in cash, generally in equal quarterly
installments over a period of up to ten (10) years (depending on the
Compensation Agreement) beginning on the date selected under the Compensation
Agreement. Each Board, in its sole discretion, may accelerate or extend the
distribution of such deferral accounts after the Deferring Director's retirement
benefits commence under the plan. Each Board, in its sole discretion, also may
accelerate or extend the distribution of such deferral accounts after the
Deferring Director's termination of service as a director of a Company. If a
Deferring Director dies prior to the distribution of amounts in his or her
deferral account, the balance of the deferral account will be distributed to his
or her designated beneficiary. The Compensation Agreements are not funded and,
with respect to the payments of amounts held in the deferral accounts, the
Deferring Directors have the status of unsecured creditors of the Companies and
of each other AIM Fund from which they are deferring compensation.

                                  PROPOSAL 2 -
             APPROVAL OF THE STIC PLAN TO REDOMESTICATE EACH SERIES
                     PORTFOLIO OF SHORT-TERM INVESTMENTS CO.
            AS NEW SERIES PORTFOLIOS OF SHORT-TERM INVESTMENTS TRUST

WHICH FUNDS' SHAREHOLDERS WILL VOTE ON PROPOSAL 2?

         Proposal 2 applies only to the shareholders of Cash Assets Portfolio,
Liquid Assets Portfolio and Prime Portfolio.

BACKGROUND

         Short-Term Investments Co. ("STIC") currently is organized as a
Maryland corporation. AMVESCAP has identified each series portfolio of STIC as
appropriate to be redomesticated as new series portfolios of Short-Term
Investments Trust ("STIT"), an existing open-end

                                       14



management investment company organized as a statutory trust under the Delaware
Statutory Trust Act.

         STIC's Board of Directors (the "STIC Board") has approved the STIC
Plan, which provides for a series of transactions to convert each of Cash Assets
Portfolio, Liquid Assets Portfolio and Prime Portfolio (each, a "Current Fund")
to a corresponding series (a "New Fund") of STIT. Under the STIC Plan, each
Current Fund will transfer all of its assets to a corresponding New Fund in
exchange solely for voting shares of beneficial interest in the New Fund and the
New Fund's assumption of all of the Current Fund's liabilities (collectively,
the "STIC Redomestication"). A form of the STIC Plan relating to the proposed
STIC Redomestication is set forth in Appendix I. If Proposal 2 is not approved
by the STIC shareholders, STIC will continue to operate as a Maryland
corporation.

         Approval of the STIC Plan requires the affirmative vote of a majority
of the issued and outstanding shares of STIC.

         The STIC Redomestication is being proposed primarily to provide STIC
with greater flexibility in conducting its business operations. The operations
of each New Fund following the STIC Redomestication will be substantially
similar to those of its predecessor Current Fund. As described below, STIT's
Amended and Restated Agreement and Declaration of Trust, as amended (the "STIT
Declaration") differs from STIC's Articles of Incorporation, and the amendments
and supplements thereto (the "STIC Articles of Incorporation") in certain
respects that are expected to improve STIC's and each Current Fund's operations.

REASONS FOR THE PROPOSED STIC REDOMESTICATION

         The STIC Redomestication is being proposed because, as noted above, AIM
and the STIC Board believe that the Delaware statutory trust organizational form
offers a number of advantages over the Maryland corporate organizational form.
As a result of these advantages, the Delaware statutory trust organizational
form has been increasingly used by mutual funds, including the majority of the
AIM Funds. STIT, like STIC, will operate as an open-end management investment
company registered with the Securities and Exchange Commission (the "SEC") under
the 1940 Act.

         The Delaware statutory trust organizational form offers greater
flexibility than the Maryland corporate form. A Maryland corporation is governed
by the detailed requirements imposed by Maryland corporate law and by the terms
of its articles of incorporation. A Delaware statutory trust is subject to fewer
statutory requirements. STIT is governed primarily by the terms of the STIT
Declaration. In particular, STIT has greater flexibility to conduct business
without the necessity of engaging in expensive proxy solicitations to
shareholders. For example, under Maryland corporate law, amendments to the STIC
Articles of Incorporation would typically require shareholder approval. Under
Delaware law, unless the Declaration of Trust of a Delaware statutory trust
provides otherwise, amendments to it may be made without first obtaining
shareholder approval. In addition, unlike Maryland corporate law, which
restricts the delegation of a board of directors' functions, Delaware law
permits the board of trustees of a Delaware statutory trust to delegate certain
of its responsibilities. For example, the board of trustees of a Delaware
statutory trust may delegate the responsibility of declaring dividends to duly
empowered committees of the board or to appropriate officers. Finally, Delaware
law permits the trustees to adapt a Delaware statutory trust to future
contingencies. For example, the

                                       15



trustees may, without a shareholder vote, change a Delaware statutory trust's
domicile or organizational form. In contrast, under Maryland corporate law, a
company's board of directors would be required to obtain shareholder approval
prior to changing domicile or organizational form.

         The STIC Redomestication will also have certain other effects on STIC,
its shareholders and management, which are described below under the heading
"STIT Compared to STIC."

WHAT THE PROPOSED STIC REDOMESTICATION WILL INVOLVE

         To accomplish the STIC Redomestication, each New Fund has been
established as a series of STIT. On the closing date, each Current Fund will
transfer all of its assets to the corresponding classes of the corresponding New
Fund in exchange solely for a number of full and fractional shares of the New
Fund equal to the number of full and fractional shares of common stock of the
corresponding classes of the Current Fund then outstanding and the New Fund's
assumption of the Current Fund's liabilities. Immediately thereafter, each
Current Fund will distribute those New Fund shares to its shareholders in
complete liquidation of such Current Fund. Upon completion of the STIC
Redomestication, each shareholder of each Current Fund will be the owner of full
and fractional shares of the corresponding New Fund equal in number and
aggregate net asset value to the shares he or she held in the Current Fund. As
soon as practicable after the consummation of the STIC Redomestication, each
Current Fund will be terminated and STIC will be dissolved as a Maryland
corporation.

         The obligations of STIC and STIT under the STIC Plan are subject to
various conditions stated therein. To provide against unforeseen events, the
STIC Plan may be terminated or amended at any time prior to the closing of the
STIC Redomestication by action of the STIC Board, notwithstanding the approval
of the STIC Plan by the shareholders of any Current Fund. However, no amendments
may be made that would materially adversely affect the interests of shareholders
of any Current Fund. STIC and STIT may at any time waive compliance with any
condition contained in the STIC Plan, provided that the waiver does not
materially adversely affect the interests of shareholders of any Current Fund.

         The STIC Plan authorizes STIC to acquire one share of each class of
each New Fund and, as the sole shareholder of each New Fund prior to the STIC
Redomestication, to do each of the following:

         -        Approve with respect to each New Fund a new investment
                  advisory agreement with AIM that will be substantially
                  identical to STIC's current investment advisory agreement with
                  AIM.

         -        Approve with respect to each New Fund a new administrative
                  services agreement with AIM that will be substantially
                  identical to each Current Fund's existing administrative
                  services agreement with AIM.

         -        Approve with respect to each New Fund a distribution agreement
                  with AIM Distributors. The proposed distribution agreement
                  will provide for substantially identical distribution services
                  as currently provided to each corresponding Current Fund by
                  AIM Distributors.

                                       16



         -        Approve a distribution plan pursuant to Rule 12b-1 under the
                  1940 Act with respect to each class of each New Fund that will
                  be substantially identical to the corresponding Current Fund's
                  existing distribution plan for that class.

         -        Approve with respect to each New Fund a custodian agreement
                  with State Street Bank and Trust Company and a transfer agency
                  and servicing agreement with A I M Fund Services, Inc., each
                  of which currently provides such services to the corresponding
                  Current Fund, and a multiple class plan pursuant to Rule 18f-3
                  of the 1940 Act which will be substantially identical to the
                  multiple class plan that exists for the corresponding Current
                  Fund.

         -        Ratify the selection of Tait, Weller & Baker, the accountants
                  for each Current Fund, as the independent public accountants
                  for each New Fund.

         -        Approve such other agreements and plans as are necessary for
                  each New Fund's operation as a series of an open-end
                  management investment company.

         STIT's transfer agent will establish for each shareholder an account
containing the appropriate number of shares of each class of each New Fund. Such
accounts will be identical in all respects to the accounts currently maintained
by STIC's transfer agent for each shareholder of the Current Funds. Shares held
in the Current Fund accounts will automatically be designated as shares of the
New Funds. Certificates for Current Fund shares issued before the STIC
Redomestication will represent shares of the corresponding New Fund after the
Redomestication. Shareholders of the New Funds will not have the right to demand
or require STIT to issue share certificates. Any account options or privileges
on accounts of shareholders under the Current Funds will be replicated on the
New Fund account. No sales charges will be imposed in connection with the STIC
Redomestication.

         Assuming your approval of Proposal 2, STIC currently contemplates that
the STIC Redomestication will be consummated on November 4, 2003.

THE FEDERAL INCOME TAX CONSEQUENCES OF THE STIC REDOMESTICATION

         STIC and STIT will receive an opinion of Ballard Spahr Andrews &
Ingersoll, LLP to the effect that the STIC Redomestication will qualify as a
"reorganization" within the meaning of Section 368(a) of the Internal Revenue
Code of 1986, as amended. Accordingly, the Current Funds, the New Funds and the
shareholders of the New Funds will recognize no gain or loss for Federal income
tax purposes as a result of the STIC Redomestication. Shareholders of the
Current Funds should consult their tax advisers regarding the effect, if any, of
the STIC Redomestication in light of their individual circumstances and as to
state and local consequences, if any, of the STIC Redomestication.

APPRAISAL RIGHTS

         Appraisal rights are not available to shareholders. However,
shareholders retain the right to redeem their shares of the Current Funds or the
New Funds, as the case may be, at any time before or after the STIC
Redomestication.

                                       17



STIT COMPARED TO STIC

         Structure of STIT

         STIT is an existing statutory trust established under the laws of the
State of Delaware by the filing of a certificate of trust in the office of the
Secretary of State of Delaware. STIT has established new series portfolios
corresponding to and having identical designations as the series portfolios of
STIC except that the new series portfolio corresponding to the Prime Portfolio
of STIC will be designated "STIC Prime." STIT has also established classes with
respect to each New Fund corresponding to and having identical designations as
the classes of each Current Fund. Each New Fund will have the same investment
objectives, policies, and restrictions as its predecessor Current Fund. STIT's
fiscal year is the same as that of STIC. No New Fund will have any operations
prior to the STIC Redomestication. Initially, STIC will be the sole shareholder
of each New Fund.

         As a Delaware statutory trust, STIT's operations are governed by the
STIT Declaration, STIT's Amended and Restated Bylaws (the "STIT Bylaws") and
applicable Delaware law rather than by the STIC Articles of Incorporation and
STIC's Amended and Restated Bylaws (the "STIC Bylaws") and applicable Maryland
law. Certain differences between the two domiciles and organizational forms are
summarized below. The operations of STIT will continue to be subject to the
provisions of the 1940 Act and the rules and regulations thereunder.

         Trustees and Officers of STIT

         Subject to the provisions of the STIT Declaration, the business of STIT
is managed by its trustees, who have all powers necessary or convenient to carry
out their responsibilities. The responsibilities, powers, and fiduciary duties
of the trustees of STIT are substantially the same as those of the directors of
STIC.

         All of the current officers of STIC currently serve as officers of STIT
and those current officers of STIC will perform the same functions on behalf of
the New Funds and STIT following the STIC Restructuring that they now perform on
behalf of the Current Funds and STIC.

         Shares of STIT

         The beneficial interests in the New Funds will be represented by
transferable shares, par value $0.01 per share. Shareholders do not have the
right to demand or require STIT to issue share certificates. The trustees have
the power under the STIT Declaration to establish new series and classes of
shares; STIC's directors currently have a similar right. The STIT Declaration
permits the trustees to issue an unlimited number of shares of each class and
series. STIC is authorized to issue only the number of shares specified in the
STIC Articles of Incorporation and may issue additional shares only with STIC
Board approval and after payment of a fee to the State of Maryland on any
additional shares authorized.

         Your Fund currently has the classes of shares set forth in Exhibit A.
STIT has established for each New Fund the classes that currently exist for its
predecessor Current Fund. Except as discussed in this Proxy Statement, shares of
each class of each New Fund will have rights, privileges, and terms
substantially similar to those of the corresponding class of the Current Fund.

                                       18



         Liability of Shareholders

         Shareholders of a Maryland corporation generally do not have personal
liability for the corporation's obligations, except that a shareholder may be
liable to the extent that he or she receives any distribution which exceeds the
amount which he or she could properly receive under Maryland law or where such
liability is necessary to prevent fraud.

         The Delaware Statutory Trust Act provides that shareholders of a
Delaware statutory trust shall be entitled to the same limitations of liability
extended to shareholders of private for-profit corporations. There is, however,
a remote possibility that, under certain circumstances, shareholders of a
Delaware statutory trust might be held personally liable for the trust's
obligations to the extent the courts of another state that does not recognize
such limited liability were to apply the laws of such state to a controversy
involving such obligations. The STIT Declaration provides that shareholders of
STIT shall not be subject to any personal liability for acts or obligations of
STIT and that every written agreement, obligation or other undertaking made or
issued by STIT shall contain a provision to the effect that shareholders are not
personally liable thereunder. In addition, the STIT Declaration provides for
indemnification out of STIT's property for any shareholder held personally
liable solely by reason of his or her being or having been a shareholder.
Therefore, the risk of any shareholder incurring financial loss beyond his or
her investment due to shareholder liability is limited to circumstances in which
STIT itself is unable to meet its obligations and the express disclaimer of
shareholder liabilities is determined not to be effective. Given the nature of
the assets and operations of STIT, the possibility of STIT being unable to meet
its obligations is considered remote, and even if a claim were brought against
STIT and a court determined that shareholders were personally liable, it would
likely not impose a material obligation on a shareholder.

         Election of Directors/Trustees; Terms

         The shareholders of STIC have elected a majority of the directors of
STIC. Each director serves until a successor is elected, subject to his or her
earlier death, resignation or removal in the manner provided by law (see below).
In the case of a vacancy on the STIC Board (other than a vacancy created by
removal by the shareholders), a majority of the directors may appoint a
successor to fill such vacancy. The right of the STIC Board to appoint directors
to fill vacancies without shareholder approval is subject to the provisions of
the 1940 Act.

         The current shareholders of STIT have elected the trustees of STIT.
Such trustees serve for the life of STIT, subject to his or her earlier death,
incapacitation, resignation, retirement or removal (see below). In the case of
any vacancy on the Board of Trustees of STIT (the "STIT Board"), a majority of
the trustees may appoint a successor to fill such vacancy. The right of the STIT
Board to appoint trustees to fill vacancies without shareholder approval is
subject to the provisions of the 1940 Act.

         Removal of Directors/Trustees

         A director of STIC may be removed by the affirmative vote of a majority
of the STIC Board, a committee of the STIC Board appointed for such purpose, or
the holders of a majority of the outstanding shares of STIC.

         A trustee of STIT may be removed at any time by a written instrument
signed by at least two-thirds of the trustees or by vote of two-thirds of the
outstanding shares of STIT.

                                       19



         Meetings of Shareholders

         STIC is not required to hold annual meetings of shareholders and does
not intend to do so unless required by the 1940 Act. The STIC Bylaws provide
that a special meeting of shareholders may be called by the president or, in his
or her absence, the vice-president or by a majority of the STIC Board or holders
of shares entitled to cast at least 10% of the votes entitled to be cast at the
special meeting. Requests for special meetings must, among other things, state
the purpose of such meeting and the matters to be voted upon. No special meeting
needs to be called to consider any matter previously voted upon at a special
meeting called by the shareholders during the preceding twelve months, unless
requested by a majority of all shares entitled to vote at such meeting.

         STIT is not required to hold annual meetings of shareholders unless
required by the 1940 Act and does not intend to do so. The STIT Bylaws provide
that any trustee may call a special meeting of shareholders and the trustees
shall call a special meeting of the shareholders solely for the purpose of
removing one or more trustees upon written request of the holders of not less
than 10% of the outstanding shares of STIT. Special meetings may be called for
the purpose of electing trustees or for any other action requiring shareholder
approval, or for any matter deemed by the trustees to be necessary or desirable.

         Liability of Directors/Trustees and Officers; Indemnification

         Maryland law permits a corporation to eliminate liability of its
directors and officers to the corporation or its stockholders, except for
liability arising from receipt of an improper benefit or profit and from active
and deliberate dishonesty. The STIC Articles of Incorporation eliminate director
and officer liability to the fullest extent permitted under Maryland law. Under
Maryland law, indemnification of a corporation's directors and officers is
mandatory if a director or officer has been successful on the merits or
otherwise in the defense of certain proceedings. Maryland law permits
indemnification for other matters unless it is established that the act or
omission giving rise to the proceeding was committed in bad faith, a result of
active and deliberate dishonesty, or one in which a director or officer actually
received an improper benefit.

         Delaware law provides that trustees of a statutory trust shall not be
liable to the statutory trust or its shareholders for acting in good faith
reliance on the provisions of its governing instrument and that the trustee's
liabilities may be expanded or restricted by such instrument. Under the STIT
Declaration, the trustees and officers of STIT are not liable for any act or
omission or any conduct whatsoever in their capacity as trustees, except for
liability to the trust or shareholders due to willful misfeasance, bad faith,
gross negligence or reckless disregard of the duties involved in the conduct of
the office of trustee. Delaware law allows a statutory trust to indemnify and
hold harmless any trustee or other person against any and all claims and
demands. The STIT Declaration provides for the indemnification of its trustees
and officers to the extent that such trustees and officers act in good faith and
reasonably believe that their conduct is in the best interests of STIT, except
with respect to any matter in which it has been determined that such trustee
acted with willful misfeasance, bad faith, gross negligence or reckless
disregard of his or her duties.

                                       20



         Dissolution and Termination

         Maryland law provides that STIC may be dissolved by the vote of a
majority of the STIC Board and two-thirds of the shares entitled to vote on the
dissolution; however the STIC Articles of Incorporation reduce the required
shareholder vote from two-thirds to a majority of the shares entitled to vote on
the dissolution.

         Pursuant to the STIT Declaration, STIT or any series or class of shares
of beneficial interest in STIT may be terminated by: (1) a majority shareholder
vote of STIT or the affected series or class, respectively; or (2) if there are
fewer than 100 shareholders of record of STIT or of such terminating series or
class, the trustees pursuant to written notice to the shares of STIT or the
affected series or class.

         Voting Rights of Shareholders

         Shareholders of a Maryland corporation such as STIC are entitled to
vote on, among other things, those matters which effect fundamental changes in
the corporate structure (such as a merger, consolidation or sale of
substantially all of the assets of the corporation) as provided by Maryland law.

         The STIT Declaration grants shareholders power to vote only with
respect to the following: (i) election of trustees, provided that a meeting of
shareholders has been called for that purpose; (ii) removal of trustees,
provided that a meeting of shareholders has been called for that purpose; (iii)
termination of STIT or a series or class of its shares of beneficial interest,
provided that a meeting of shareholders has been called for that purpose; (iv)
sale of all or substantially all of the assets of STIT or one of its investment
portfolios; (v) merger or consolidation of STIT or any of its investment
portfolios, with certain exceptions; (vi) approval of any amendments to
shareholders' voting rights under the STIT Declaration; and (vii) approval of
such additional matters as may be required by law or as the trustees, in their
sole discretion, shall determine.

         Dissenters' Rights

         Under Maryland law, shareholders may not demand the fair value of their
shares from the successor company in a transaction involving the transfer of the
corporation's assets and are, therefore, bound by the terms of the transaction
if the stock is that of an open-end investment company registered with the SEC
under the 1940 Act and the value placed on the stock in the transaction is its
net asset value.

         Neither Delaware law nor the STIT Declaration confer upon shareholders
rights of appraisal or dissenters' rights.

         Amendments to Organization Documents

         STIC has the right to amend, alter, change or repeal any provision
contained in the STIC Articles of Incorporation in the manner prescribed by
statute, including any amendment that alters the contract rights, as expressly
set forth in the STIC Articles of Incorporation, of any outstanding stock, and
all rights conferred on shareholders are granted subject to this reservation.
The STIC Board may approve amendments to the STIC Articles of Incorporation to
classify or reclassify unissued shares of a class of stock without shareholder
approval. Other amendments

                                       21



to the STIC Articles of Incorporation may be adopted if approved by the
affirmative vote of a majority of all the votes entitled to be cast on the
matter. The directors have the power to alter, amend or repeal the STIC Bylaws
or adopt new bylaws at any time.

         Consistent with Delaware law, the STIT Board may, without shareholder
approval, amend the STIT Declaration at any time, except to eliminate any voting
rights pertaining to the shares of STIT, without approval of the majority of the
shares of STIT. The trustees have the power to alter, amend or repeal the STIT
Bylaws or adopt new bylaws at any time.

         The foregoing is only a summary of certain differences between and
among the STIC Articles of Incorporation and the STIC Bylaws and Maryland law,
and the STIT Declaration and STIT Bylaws and Delaware law. It is not a complete
list of the differences. Shareholders should refer to the provisions of the
governing documents of STIC and STIT and state law directly for a more thorough
comparison. Copies of the STIC Articles of Incorporation and STIC Bylaws and of
the STIT Declaration and STIT Bylaws are available to shareholders without
charge upon written request to STIC.

THE BOARD'S RECOMMENDATION ON PROPOSAL 2

         Your Board, including the independent directors, unanimously recommends
that you vote "FOR" this Proposal.

                                  PROPOSAL 3 -
                   APPROVAL OF THE TFIC PLAN TO REDOMESTICATE
             TAX-FREE INVESTMENTS CO. AS A DELAWARE STATUTORY TRUST

WHICH FUNDS' SHAREHOLDERS WILL VOTE ON PROPOSAL 3?

         Proposal 3 applies only to the shareholders of Cash Reserve Portfolio.

BACKGROUND

         Tax-Free Investments Co. ("TFIC") currently is organized as a Maryland
corporation. AMVESCAP has identified Cash Reserve Portfolio, the sole series
portfolio of TFIC, as appropriate to be redomesticated as a new series portfolio
of Tax-Free Investments Trust ("TFIT"), a newly created open-end management
investment company organized as a statutory trust under the Delaware Statutory
Trust Act.

         TFIC's Board of Directors (the "TFIC Board") has approved the TFIC
Plan, which provides for a series of transactions to convert Cash Reserve
Portfolio (the "Current Fund") to a corresponding series (the "New Fund") of
TFIT. Under the TFIC Plan, the Current Fund will transfer all of its assets to
the New Fund in exchange solely for voting shares of beneficial interest in the
New Fund and the New Fund's assumption of all of the Current Fund's liabilities
(collectively, the "TFIC Redomestication"). A form of the TFIC Plan relating to
the proposed TFIC Redomestication is set forth in Appendix I. If Proposal 3 is
not approved by the TFIC shareholders, TFIC will continue to operate as a
Maryland corporation.

         Approval of the TFIC Plan requires the affirmative vote of a majority
of the issued and outstanding shares of TFIC.

                                       22



         The TFIC Redomestication is being proposed primarily to provide TFIC
with greater flexibility in conducting its business operations. The operations
of the New Fund following the TFIC Redomestication will be substantially similar
to those of the Current Fund. As described below, TFIT's Declaration of Trust
(the "TFIT Declaration") differs from TFIC's Articles of Incorporation and the
amendments and supplements thereto (the "TFIC Articles of Incorporation") in
certain respects that are expected to improve TFIC's and the Current Fund's
operations.

REASONS FOR THE PROPOSED TFIC REDOMESTICATION

         The TFIC Redomestication is being proposed because, as noted above, AIM
and the TFIC Board believe that the Delaware statutory trust organizational form
offers a number of advantages over the Maryland corporate organizational form.
As a result of these advantages, the Delaware statutory trust organizational
form has been increasingly used by mutual funds, including the majority of the
AIM Funds. TFIT, like TFIC, will operate as an open-end management investment
company registered with the Securities and Exchange Commission (the "SEC") under
the 1940 Act. As permitted by SEC rules, TFIT will adopt as its own the
registration statement of TFIC.

         The Delaware statutory trust organizational form offers greater
flexibility than the Maryland corporate form. A Maryland corporation is governed
by the detailed requirements imposed by Maryland corporate law and by the terms
of its articles of incorporation. A Delaware statutory trust is subject to fewer
statutory requirements. TFIT will be governed primarily by the terms of the TFIT
Declaration. In particular, TFIT will have greater flexibility to conduct
business without the necessity of engaging in expensive proxy solicitations to
shareholders. For example, under Maryland corporate law, amendments to the TFIC
Articles of Incorporation would typically require shareholder approval. Under
Delaware law, unless the Declaration of Trust of a Delaware statutory trust
provides otherwise, amendments to it may be made without first obtaining
shareholder approval. In addition, unlike Maryland corporate law, which
restricts the delegation of a board of directors' functions, Delaware law
permits the board of trustees of a Delaware statutory trust to delegate certain
of its responsibilities. For example, the board of trustees of a Delaware
statutory trust may delegate the responsibility of declaring dividends to duly
empowered committees of the board or to appropriate officers. Finally, Delaware
law permits the trustees to adapt a Delaware statutory trust to future
contingencies. For example, the trustees may, without a shareholder vote, change
a Delaware statutory trust's domicile or organizational form. In contrast, under
Maryland corporate law, a company's board of directors would be required to
obtain shareholder approval prior to changing domicile or organizational form.

         The TFIC Redomestication will also have certain other effects on TFIC,
its shareholders and management, which are described below under the heading
"TFIT Compared to TFIC."

WHAT THE PROPOSED TFIC REDOMESTICATION WILL INVOLVE

         To accomplish the TFIC Redomestication, TFIT has been formed as a
Delaware statutory trust pursuant to the TFIT Declaration and the New Fund has
been established as the sole series of TFIT. On the closing date, the Current
Fund will transfer all of its assets to the corresponding classes of the New
Fund in exchange solely for a number of full and fractional shares of the New

                                       23



Fund equal to the number of full and fractional shares of common stock of the
corresponding classes of the Current Fund then outstanding and the New Fund's
assumption of the Current Fund's liabilities. Immediately thereafter, the
Current Fund will distribute those New Fund shares to its shareholders in
complete liquidation of the Current Fund. Upon completion of the TFIC
Redomestication, each shareholder of the Current Fund will be the owner of full
and fractional shares of the New Fund equal in number and aggregate net asset
value to the shares he or she held in the Current Fund. As soon as practicable
after the consummation of the TFIC Redomestication, the Current Fund will be
terminated and TFIC will be dissolved as a Maryland corporation.

         The obligations of TFIC and TFIT under the TFIC Plan are subject to
various conditions stated therein. To provide against unforeseen events, the
TFIC Plan may be terminated or amended at any time prior to the closing of the
TFIC Redomestication by action of the TFIC Board, notwithstanding the approval
of the TFIC Plan by the shareholders of the Current Fund. However, no amendments
may be made that would materially adversely affect the interests of shareholders
of the Current Fund. TFIC and TFIT may at any time waive compliance with any
condition contained in the TFIC Plan, provided that the waiver does not
materially adversely affect the interests of shareholders of the Current Fund.

         The TFIC Plan authorizes TFIC to acquire one share of each class of the
New Fund and, as the sole shareholder of the New Fund prior to the TFIC
Redomestication, to do each of the following:

         -        Approve with respect to the New Fund a new investment advisory
                  agreement with AIM that will be substantially identical to
                  TFIC's current investment advisory agreement with AIM.

         -        Approve with respect to the New Fund a administrative services
                  agreement with AIM that will be substantially identical to the
                  Current Fund's existing administrative services agreement with
                  AIM.

         -        Approve with respect to the New Fund a distribution agreement
                  with AIM Distributors. The proposed distribution agreement
                  will provide for substantially identical distribution services
                  as currently provided to the Current Fund by AIM Distributors.

         -        Approve a distribution plan pursuant to Rule 12b-1 under the
                  1940 Act with respect to each class of the New Fund that will
                  be substantially identical to the Current Fund's existing
                  distribution plan for that class.

         -        Approve with respect to the New Fund a custodian agreement
                  with State Street Bank and Trust Company and a transfer agency
                  and servicing agreement with A I M Fund Services, Inc., each
                  of which currently provides such services to the Current Fund,
                  and a multiple class plan pursuant to Rule 18f-3 of the 1940
                  Act which will be substantially identical to the multiple
                  class plan that exists for the Current Fund.

                                       24



         -        Elect the directors of TFIC as the trustees of TFIT to serve
                  without limit in time, except as they may resign or be removed
                  by action of TFIT's trustees or shareholders, and except as
                  they retire in accordance with TFIT's retirement policy for
                  trustees. TFIT's retirement policy for trustees is
                  substantially identical to TFIC's retirement policy for
                  directors.

         -        Ratify the selection of Ernst & Young LLP as the independent
                  public accountants for the New Fund.

         -        Approve such other agreements and plans as are necessary for
                  the New Fund's operation as a series of an open-end management
                  investment company.

         TFIT's transfer agent will establish for each shareholder an account
containing the appropriate number of shares of each class of the New Fund. Such
accounts will be identical in all respects to the accounts currently maintained
by TFIC's transfer agent for each shareholder of the Current Fund. Shares held
in the Current Fund accounts will automatically be designated as shares of the
New Fund. Certificates for Current Fund shares issued before the TFIC
Redomestication will represent shares of the New Fund after the TFIC
Redomestication. Shareholders of the New Fund will not have the right to demand
or require TFIT to issue share certificates. Any account options or privileges
on accounts of shareholders under the Current Fund will be replicated on the New
Fund account. No sales charges will be imposed in connection with the TFIC
Redomestication.

         Assuming your approval of Proposal 3, TFIC currently contemplates that
the TFIC Redomestication will be consummated on November 4, 2003.

THE FEDERAL INCOME TAX CONSEQUENCES OF THE TFIC REDOMESTICATION

         TFIC and TFIT will receive an opinion of Ballard Spahr Andrews &
Ingersoll, LLP to the effect that the TFIC Redomestication will qualify as a
"reorganization" within the meaning of Section 368(a) of the Internal Revenue
Code of 1986, as amended. Accordingly, the Current Fund, the New Fund and the
shareholders of the New Fund will recognize no gain or loss for Federal income
tax purposes as a result of the TFIC Redomestication. Shareholders of the
Current Fund should consult their tax advisers regarding the effect, if any, of
the TFIC Redomestication in light of their individual circumstances and as to
state and local consequences, if any, of the TFIC Redomestication.

APPRAISAL RIGHTS

         Appraisal rights are not available to shareholders. However,
shareholders retain the right to redeem their shares of the Current Fund or the
New Fund, as the case may be, at any time before or after the TFIC
Redomestication.

                                       25



TFIT COMPARED TO TFIC

         Structure of TFIT

         TFIT has been established under the laws of the State of Delaware by
the filing of a certificate of trust in the office of the Secretary of State of
Delaware. TFIT has established a sole series portfolio corresponding to Cash
Reserve Portfolio, the sole series portfolio of TFIC, except that the new series
portfolio will be designated "Tax-Free Cash Reserve Portfolio." TFIT has also
established classes with respect to the New Fund corresponding to and having
identical designations as the classes of the Current Fund. TFIT's fiscal year is
the same as that of TFIC. The New Fund will have the same investment objectives,
policies, and restrictions as the predecessor Current Fund. TFIT will not have
any operations prior to the TFIC Redomestication. Initially, TFIC will be the
sole shareholder of TFIT.

         As a Delaware statutory trust, TFIT's operations are governed by the
TFIT Declaration, TFIT's Bylaws and applicable Delaware law rather than by the
TFIC Articles of Incorporation, TFIC's Amended and Restated Bylaws (the "TFIC
Bylaws") and applicable Maryland law. Certain differences between the two
domiciles and organizational forms are summarized below. The operations of TFIT
will continue to be subject to the provisions of the 1940 Act and the rules and
regulations thereunder.

         Trustees of TFIT

         Subject to the provisions of the TFIT Declaration, the business of TFIT
will be managed by its trustees, who have all powers necessary or convenient to
carry out their responsibilities. The responsibilities, powers, and fiduciary
duties of the trustees of TFIT are substantially the same as those of the
directors of TFIC.

         The trustees of TFIT would be those persons elected at this Special
Meeting to serve as directors of TFIC. Information concerning the nominees for
election as directors of TFIC is set forth above under Proposal 1.

         Shares of TFIT

         The beneficial interests in the New Fund will be represented by
transferable shares, par value $0.001 per share. Shareholders do not have the
right to demand or require TFIT to issue share certificates. The trustees have
the power under the TFIT Declaration to establish new series and classes of
shares; TFIC's directors currently have a similar right. The TFIT Declaration
permits the trustees to issue an unlimited number of shares of each class and
series. TFIC is authorized to issue only the number of shares specified in the
TFIC Articles of Incorporation and may issue additional shares only with TFIC
Board approval and after payment of a fee to the State of Maryland on any
additional shares authorized.

         Your Fund currently has the classes of shares set forth in Exhibit A.
TFIT has established for the New Fund the classes that currently exist for the
Current Fund. Except as discussed in this Proxy Statement, shares of each class
of the New Fund will have rights, privileges, and terms substantially similar to
those of the corresponding class of the Current Fund.

                                       26



         Liability of Shareholders

         Shareholders of a Maryland corporation generally do not have personal
liability for the corporation's obligations, except that a shareholder may be
liable to the extent that he or she receives any distribution which exceeds the
amount which he or she could properly receive under Maryland law or where such
liability is necessary to prevent fraud.

         The Delaware Statutory Trust Act provides that shareholders of a
Delaware statutory trust shall be entitled to the same limitations of liability
extended to shareholders of private for-profit corporations. There is, however,
a remote possibility that, under certain circumstances, shareholders of a
Delaware statutory trust might be held personally liable for the trust's
obligations to the extent the courts of another state that does not recognize
such limited liability were to apply the laws of such state to a controversy
involving such obligations. The TFIT Declaration provides that shareholders of
TFIT shall not be subject to any personal liability for acts or obligations of
TFIT and that every written agreement, obligation or other undertaking made or
issued by TFIT shall contain a provision to the effect that shareholders are not
personally liable thereunder. In addition, the TFIT Declaration provides for
indemnification out of TFIT's property for any shareholder held personally
liable solely by reason of his or her being or having been a shareholder.
Therefore, the risk of any shareholder incurring financial loss beyond his or
her investment due to shareholder liability is limited to circumstances in which
TFIT itself is unable to meet its obligations and the express disclaimer of
shareholder liabilities is determined not to be effective. Given the nature of
the assets and operations of TFIT, the possibility of TFIT being unable to meet
its obligations is considered remote, and even if a claim were brought against
TFIT and a court determined that shareholders were personally liable, it would
likely not impose a material obligation on a shareholder.

         Election of Directors/Trustees; Terms

         The shareholders of TFIC have elected a majority of the directors of
TFIC. Each director serves until a successor is elected, subject to his or her
earlier death, resignation or removal in the manner provided by law (see below).
In the case of a vacancy on the TFIC Board (other than a vacancy created by
removal by the shareholders), a majority of the directors may appoint a
successor to fill such vacancy. The right of the TFIC Board to appoint directors
to fill vacancies without shareholder approval is subject to the provisions of
the 1940 Act.

         As set forth above, the TFIC Plan authorizes TFIC to acquire one share
of each class of the New Fund and, as the sole shareholder of TFIT prior to the
TFIC Redomestication, to elect the directors of TFIC as the trustees of TFIT.
Such trustees serve for the life of TFIT, subject to his or her earlier death,
incapacitation, resignation, retirement or removal (see below). In the case of
any vacancy on the Board of Trustees of TFIT (the "TFIT Board"), a majority of
the trustees may appoint a successor to fill such vacancy. The right of the TFIT
Board to appoint trustees to fill vacancies without shareholder approval is
subject to the provisions of the 1940 Act.

         Removal of Directors/Trustees

         A director of TFIC may be removed by the affirmative vote of a majority
of the holders of a majority of the outstanding shares of TFIC.

                                       27



         A trustee of TFIT may be removed at any time by a written instrument
signed by at least two-thirds of the trustees or by vote of two-thirds of the
outstanding shares of TFIT.

         Meetings of Shareholders

         TFIC is not required to hold annual meetings of shareholders and does
not intend to do so unless required by the 1940 Act. The TFIC Bylaws provide
that a special meeting of shareholders may be called by the president or, in his
or her absence, the vice-president or by a majority of the TFIC Board or holders
of shares entitled to cast at least 10% of the votes entitled to be cast at the
special meeting. Requests for special meetings must, among other things, state
the purpose of such meeting and the matters to be voted upon. No special meeting
needs to be called to consider any matter previously voted upon at a special
meeting called by the shareholders during the preceding twelve months, unless
requested by a majority of all shares entitled to vote at such meeting.

         TFIT is not required to hold annual meetings of shareholders unless
required by the 1940 Act and does not intend to do so. The TFIT Bylaws provide
that any trustee may call a special meeting of shareholders and the trustees
shall call a special meeting of the shareholders solely for the purpose of
removing one or more trustees upon written request of the holders of not less
than 10% of the outstanding shares of TFIT. Special meetings may be called for
the purpose of electing trustees or for any other action requiring shareholder
approval, or for any matter deemed by the trustees to be necessary or desirable.

         Liability of Directors/Trustees and Officers; Indemnification

         Maryland law permits a corporation to eliminate liability of its
directors and officers to the corporation or its stockholders, except for
liability arising from receipt of an improper benefit or profit and from active
and deliberate dishonesty. The TFIC Articles of Incorporation eliminate director
and officer liability to the fullest extent permitted under Maryland law. Under
Maryland law, indemnification of a corporation's directors and officers is
mandatory if a director or officer has been successful on the merits or
otherwise in the defense of certain proceedings. Maryland law permits
indemnification for other matters unless it is established that the act or
omission giving rise to the proceeding was committed in bad faith, a result of
active and deliberate dishonesty, or one in which a director or officer actually
received an improper benefit.

         Delaware law provides that trustees of a statutory trust shall not be
liable to the statutory trust or its shareholders for acting in good faith
reliance on the provisions of its governing instrument and that the trustee's
liabilities may be expanded or restricted by such instrument. Under the TFIT
Declaration, the trustees and officers of TFIT are not liable for any act or
omission or any conduct whatsoever in their capacity as trustees, except for
liability to the trust or shareholders due to willful misfeasance, bad faith,
gross negligence or reckless disregard of the duties involved in the conduct of
the office of trustee. Delaware law allows a statutory trust to indemnify and
hold harmless any trustee or other person against any and all claims and
demands. The TFIT Declaration provides for the indemnification of its trustees
and officers to the extent that such trustees and officers act in good faith and
reasonably believe that their conduct is in the best interests of TFIT, except
with respect to any matter in which it has been determined that such trustee
acted with willful misfeasance, bad faith, gross negligence or reckless
disregard of his or her duties.

                                       28



         Dissolution and Termination

         Maryland law provides that TFIC may be dissolved by the vote of a
majority of the TFIC Board and two-thirds of the shares entitled to vote on the
dissolution; however the TFIC Articles of Incorporation reduce the required
shareholder vote from two-thirds to a majority of the shares entitled to vote on
the dissolution.

         Pursuant to the TFIT Declaration, TFIT or any series or class of shares
of beneficial interest in TFIT may be terminated by: (1) a majority shareholder
vote of TFIT or the affected series or class, respectively; or (2) if there are
fewer than 100 shareholders of record of TFIT or of such terminating series or
class, the trustees pursuant to written notice to the shares of TFIT or the
affected series or class.

         Voting Rights of Shareholders

         Shareholders of a Maryland corporation such as TFIC are entitled to
vote on, among other things, those matters which effect fundamental changes in
the corporate structure (such as a merger, consolidation or sale of
substantially all of the assets of the corporation) as provided by Maryland law.

         The TFIT Declaration grants shareholders power to vote only with
respect to the following: (i) election of trustees, provided that a meeting of
shareholders has been called for that purpose; (ii) removal of trustees,
provided that a meeting of shareholders has been called for that purpose; (iii)
termination of TFIT or a series or class of its shares of beneficial interest,
provided that a meeting of shareholders has been called for that purpose; (iv)
sale of all or substantially all of the assets of TFIT or one of its investment
portfolios; (v) merger or consolidation of TFIT or any of its investment
portfolios, with certain exceptions; (vi) approval of any amendments to
shareholders' voting rights under the TFIT Declaration; and (vii) approval of
such additional matters as may be required by law or as the trustees, in their
sole discretion, shall determine.

         Dissenters' Rights

         Under Maryland law, shareholders may not demand the fair value of their
shares from the successor company in a transaction involving the transfer of the
corporation's assets and are, therefore, bound by the terms of the transaction
if the stock is that of an open-end investment company registered with the SEC
under the 1940 Act and the value placed on the stock in the transaction is its
net asset value.

         Neither Delaware law nor the TFIT Declaration confer upon shareholders
rights of appraisal or dissenters' rights.

         Amendments to Organization Documents

         TFIC has the right to amend, alter, change or repeal any provision
contained in the TFIC Articles of Incorporation in the manner prescribed by
statute, including any amendment that alters the contract rights, as expressly
set forth in the TFIC Articles of Incorporation, of any outstanding stock, and
all rights conferred on shareholders are granted subject to this reservation.
The TFIC Board may approve amendments to the TFIC Articles of Incorporation to
classify or reclassify unissued shares of a class of stock without shareholder
approval. Other amendments

                                       29



to the TFIC Articles of Incorporation may be adopted if approved by the
affirmative vote of a majority of all the votes entitled to be cast on the
matter. The directors have the power to alter, amend or repeal the TFIC Bylaws
or adopt new bylaws at any time.

         Consistent with Delaware law, the TFIT Board may, without shareholder
approval, amend the TFIT Declaration at any time, except to eliminate any voting
rights pertaining to the shares of TFIT, without approval of the majority of the
shares of TFIT. The trustees have the power to alter, amend or repeal the TFIT
Bylaws or adopt new bylaws at any time.

         The foregoing is only a summary of certain differences between and
among the TFIC Articles of Incorporation, the TFIC Bylaws and Maryland law, and
the TFIT Declaration, TFIT Bylaws and Delaware law. It is not a complete list of
the differences. Shareholders should refer to the provisions of the governing
documents of TFIC and TFIT and state law directly for a more thorough
comparison. Copies of the TFIC Articles of Incorporation and TFIC Bylaws and of
the TFIT Declaration and TFIT Bylaws are available to shareholders without
charge upon written request to TFIC.

                                   APPENDIX I

                           SHORT-TERM INVESTMENTS CO.

                      AGREEMENT AND PLAN OF REORGANIZATION

         AGREEMENT AND PLAN OF REORGANIZATION (the "Agreement"), dated as of
July 30, 2003, by and between Short-Term Investments Co., a Maryland corporation
(the "Company"), acting on its own behalf and on behalf of each of its series
portfolios, all of which are identified on Schedule A to this Agreement, and
Short-Term Investments Trust, a Delaware statutory trust (the "Trust"), acting
on its own behalf and on behalf of each of its series portfolios, all of which
are identified on Schedule A.

                                   BACKGROUND

         The Company is organized as a series management investment company and
is registered with the Securities and Exchange Commission under the Investment
Company Act of 1940, as amended. The Company currently publicly offers shares of
common stock representing interests in one or more separate series portfolios.
Each of these series portfolios is listed on Schedule A and is referred to in
this Agreement as a "Current Fund."

         The Board of Directors of the Company has designated multiple classes
of common stock that represent interests in each Current Fund. Each of these
classes is listed on Schedule B to this Agreement and is referred to in this
Agreement as a "Current Fund Class."

         The Company desires to change its form and place of organization by
reorganizing as the Trust. In anticipation of such reorganization, the Board of
Trustees of the Trust has established a series portfolio corresponding to each
of the Current Funds (each a "New Fund"), and has designated multiple classes of
shares of beneficial interest in each New Fund corresponding to the Current Fund
Classes (each a "New Fund Class"). Schedule A lists the New Funds and Schedule B
lists the New Fund Classes.

         Each Current Fund desires to provide for its Reorganization (each, a
"Reorganization" and collectively, the "Reorganizations") through the transfer
of all of its assets to the corresponding New Fund in exchange for the
assumption by such New Fund of the liabilities of the corresponding Current Fund
and the issuance by the Trust to such Current Fund of shares of beneficial
interest in the New Fund ("New Fund Shares"). New Fund Shares received by a
Current Fund will have an aggregate net asset value equal to the aggregate net
asset value of the shares of the Current Fund immediately prior to the
Reorganization (the "Current Fund Shares"). Each Current Fund will then
distribute the New Fund Shares it has received to its shareholders.

         Each Reorganization of each Current Fund is dependent upon the
consummation of the Reorganization of all of the other Current Funds, so that
the Reorganizations of all of the Current Funds must be consummated if any of
them are to be consummated. For convenience, the balance of this Agreement
refers only to a single Reorganization, but the terms and conditions hereof
shall apply separately to each Reorganization and to the Current Fund and the
corresponding New Fund participating therein, as applicable.

         The Reorganization is subject to, and shall be effected in accordance
with, the terms of this Agreement. This Agreement is intended to be and is
adopted by the Company, on its own

                                      AP-1



behalf and on behalf of the Current Funds, and by the Trust, on its own behalf
and on behalf of the New Funds, as a Plan of Reorganization within the meaning
of the regulations under Section 368(a) of the Internal Revenue Code of 1986, as
amended.

         NOW THEREFORE, the parties hereto, intending to be legally bound,
hereby agree as follows:

1        DEFINITIONS.

under applicable securities laws, books and records, deferred and prepaid
expenses shown as assets on a Current Fund's books, and other property owned by
a Current Fund at the Effective Time.

         1.2      "Closing" shall mean the consummation of the transfer of
Assets, assumption of Liabilities and issuance of shares described in Sections
2.1 and 2.2 of this Agreement, together with the related acts necessary to
consummate the Reorganization, to occur on the date set forth in Section 3.1.

         1.3      "Code" shall mean the Internal Revenue Code of 1986, as
amended.

the Company representing an interest in a Current Fund as shown on Schedule B.

         1.6      "Current Fund Shares" shall mean the shares of a Current Fund
outstanding immediately prior to the Reorganization.

         1.7      "Effective Time" shall have the meaning set forth in Section
3.1.

         1.8      "Liabilities" shall mean all liabilities of a Current Fund
including, without limitation, all debts, obligations, and duties of whatever
kind or nature, whether absolute, accrued, contingent, or otherwise, whether or
not determinable at the Effective Time, and whether or not specifically referred
to herein.

         1.9      "New Fund" shall mean each of the series portfolios of the
Trust, one of which shall correspond to one of the Current Funds as shown on
Schedule A.

         1.10     "New Fund Class" shall mean each class of shares of beneficial
interest in a New Fund, one of which shall correspond to one of the Current Fund
Classes as shown on Schedule B.

                                      AP-2



         1.11     "New Fund Shares" shall mean those shares of beneficial
interest in a New Fund issued to a Current Fund hereunder.

2        PLAN OF REORGANIZATION.

         2.1      The Company agrees, on behalf of each Current Fund, to assign,
sell, convey, transfer and deliver all of the Assets of each Current Fund to its
corresponding New Fund. The Trust, on behalf of each New Fund, agrees in
exchange therefor:

                  (a)      to issue and deliver to the corresponding Current
         Fund the number of full and fractional (rounded to the third decimal
         place) New Fund Shares of each New Fund Class designated on Schedule B
         equal to the number of full and fractional Current Fund Shares of each
         corresponding Current Fund Class designated on Schedule B; and

                  (b)      to assume all of the Current Fund's Liabilities.

Such transactions shall take place at the Closing.

         2.2      At the Effective Time (or as soon thereafter as is reasonably
practicable), (a) the New Fund Shares issued pursuant to Section 5.2 shall be
redeemed by each New Fund for $1.00 and (b) each Current Fund shall distribute
the New Fund Shares received by it pursuant to Section 2.1 to the Current Fund's
Shareholders in exchange for such Shareholders' Current Fund Shares. Such
distribution shall be accomplished through opening accounts, by the transfer
agent for the Trust (the "Transfer Agent"), on each New Fund's share transfer
books in the Shareholders' names and transferring New Fund Shares to such
accounts. Each Shareholder's account shall be credited with the respective pro
rata number of full and fractional (rounded to the third decimal place) New Fund
Shares of each New Fund Class due that Shareholder. All outstanding Current Fund
Shares, including those represented by certificates, shall simultaneously be
canceled on each Current Fund's share transfer books. The Trust shall not issue
certificates representing the New Fund Shares in connection with the
Reorganization. However, certificates representing Current Fund Shares shall
represent New Fund Shares after the Reorganization.

                                      AP-3



         2.3      Following receipt of the required shareholder vote and as soon
as reasonably practicable after the Closing, the status of each Current Fund as
a designated series of the Company shall be terminated; provided, however, that
the termination of each Current Fund as a designated series of the Company shall
not be required if the Reorganization shall not have been consummated.

         2.4      Following receipt of the required shareholder vote and as soon
as reasonably practicable after distribution of the New Fund Shares pursuant to
Section 2.2, the Company and the Trust shall cause Articles of Transfer to be
filed with the State Department of Assessments and Taxation of Maryland and,
following the filing of Articles of Transfer, the Company shall file Articles of
Dissolution with the State Department of Assessments and Taxation of Maryland to
dissolve the Company as a Maryland corporation; provided, however, that the
filing of Articles of Transfer and Articles of Dissolution as aforesaid shall
not be required if the Reorganization shall not have been consummated.

         2.5      Any transfer taxes payable on issuance of New Fund Shares in a
name other than that of the registered holder of the Current Fund Shares
exchanged therefor shall be paid by the person to whom such New Fund Shares are
to be issued, as a condition of such transfer.

         2.6      Any reporting responsibility of the Company or each Current
Fund to a public authority is and shall remain its responsibility up to and
including the date on which it is terminated.

3.       CLOSING.

         3.1      The Closing shall occur at the principal office of the Company
on November 4, 2003, or on such other date and at such other place upon which
the parties may agree. All acts taking place at the Closing shall be deemed to
take place simultaneously as of the Company's and the Trust's close of business
on the date of the Closing or at such other time as the parties may agree (the
"Effective Time").

         3.2      The Company or its fund accounting agent shall deliver to the
Trust at the Closing, a certificate of an authorized officer verifying that the
information (including adjusted basis and holding period, by lot) concerning the
Assets, including all portfolio securities, transferred by the Current Funds to
the New Funds, as reflected on the New Funds' books immediately following the
Closing, does or will conform to such information on the Current Funds' books
immediately before the Closing. The Company shall cause the custodian for each
Current Fund to deliver at the Closing a certificate of an authorized officer of
the custodian stating that (a) the Assets held by the custodian will be
transferred to each corresponding New Fund at the Effective Time and (b) all
necessary taxes in conjunction with the delivery of the Assets, including all
applicable federal and state stock transfer stamps, if any, have been paid or
provision for payment has been made.

         3.3      The Company shall deliver to the Trust at the Closing a list
of the names and addresses of each Shareholder of each Current Fund and the
number of outstanding Current Fund Shares of the Current Fund Class owned by
each Shareholder, all as of the Effective Time, certified by the Company's
Secretary or Assistant Secretary. The Trust shall cause the Transfer

                                      AP-4



Agent to deliver at the Closing a certificate as to the opening on each New
Fund's share transfer books of accounts in the Shareholders' names. The Trust
shall issue and deliver a confirmation to the Company evidencing the New Fund
Shares to be credited to each corresponding Current Fund at the Effective Time
or provide evidence satisfactory to the Company that such shares have been
credited to each Current Fund's account on such books. At the Closing, each
party shall deliver to the other such bills of sale, checks, assignments, stock
certificates, receipts, or other documents as the other party or its counsel may
reasonably request.

         3.4      The Company and the Trust shall deliver to the other at the
Closing a certificate executed in its name by its President or a Vice President
in form and substance satisfactory to the recipient and dated the Effective
Time, to the effect that the representations and warranties it made in this
Agreement are true and correct at the Effective Time except as they may be
affected by the transactions contemplated by this Agreement.

4.       REPRESENTATIONS AND WARRANTIES.

         4.1      The Company represents and warrants on its own behalf and on
behalf of each Current Fund as follows:

                  (a)      The Company is a corporation duly organized, validly
         existing, and in good standing under the laws of the State of Maryland,
         and its Charter is on file with the Maryland Department of Assessments
         and Taxation;

                  (b)      The Company is duly registered as an open-end series
         management investment company under the 1940 Act, and such registration
         is in full force and effect;

                  (c)      Each Current Fund is a duly established and
         designated series of the Company;

                  (d)      At the Closing, each Current Fund will have good and
         marketable title to its Assets and full right, power, and authority to
         sell, assign, transfer, and deliver its Assets free of any liens or
         other encumbrances; and upon delivery and payment for the Assets, the
         corresponding New Fund will acquire good and marketable title to the
         Assets;

                  (e)      The New Fund Shares are not being acquired for the
         purpose of making any distribution thereof, other than in accordance
         with the terms hereof;

                  (f)      Each Current Fund is a "fund" as defined in Section
         851(g)(2) of the Code; each Current Fund qualified for treatment as a
         RIC for each taxable year since it commenced operations that has ended
         (or will end) before the Closing and will continue to meet all the
         requirements for such qualification for its current taxable year (and
         the Assets will be invested at all times through the Effective Time in
         a manner that ensures compliance with the foregoing); each Current Fund
         has no earnings and profits accumulated in any taxable year in which
         the provisions of Subchapter M did not apply to it; and each Current
         Fund has made all distributions for each calendar year that has ended
         (or will end) before the Closing that are necessary to avoid the
         imposition of federal excise tax or has paid or provided for the
         payment of any excise tax imposed for any such calendar year;

                                      AP-5



                  (g)      During the five-year period ending on the date of the
         Reorganization, neither Company nor any person related to Company (as
         defined in Section 1.368-1(e)(3) of the Federal income tax regulations
         adopted pursuant to the Code without regard to Section
         1.368-1(e)(3)(i)(A)) will have directly or through any transaction,
         agreement, or arrangement with any other person, (i) acquired shares of
         a Current Fund for consideration other than shares of such Current
         Fund, except for shares redeemed in the ordinary course of such Current
         Fund's business as an open-end investment company as required by the
         1940 Act, or (ii) made distributions with respect to a Current Fund's
         shares, except for (a) distributions necessary to satisfy the
         requirements of Sections 852 and 4982 of the Code for qualification as
         a regulated investment company and avoidance of excise tax liability
         and (b) additional distributions, to the extent such additional
         distributions do not exceed 50 percent of the value (without giving
         effect to such distributions) of the proprietary interest in such
         Current Fund at the Effective Time. There is no plan or intention of
         the Shareholders who individually own 5% or more of any Current Fund
         Shares and, to the best of the Company's knowledge, there is no plan or
         intention of the remaining Shareholders to redeem or otherwise dispose
         of any New Fund Shares to be received by them in the Reorganization.
         The Company does not anticipate dispositions of those shares at the
         time of or soon after the Reorganization to exceed the usual rate and
         frequency of redemptions of shares of the Current Fund as a series of
         an open-end investment company. Consequently, the Company is not aware
         of any plan that would cause the percentage of Shareholder interests,
         if any, that will be disposed of as a result of or at the time of the
         Reorganization to be one percent (1%) or more of the shares of the
         Current Fund outstanding as of the Effective Time;

                  (h)      The Liabilities were incurred by the Current Funds in
         the ordinary course of their business and are associated with the
         Assets;

                  (i)      The Company is not under the jurisdiction of a court
         in a proceeding under Title 11 of the United States Code or similar
         case within the meaning of Section 368(a)(3)(A) of the Code;

                  (j)      As of the Effective Time, no Current Fund will have
         outstanding any warrants, options, convertible securities, or any other
         type of rights pursuant to which any person could acquire Current Fund
         Shares except for the right of investors to acquire its shares at net
         asset value in the normal course of its business as a series of an
         open-end diversified management investment company operating under the
         1940 Act;

                  (k)      At the Effective Time, the performance of this
         Agreement shall have been duly authorized by all necessary action by
         the Company's shareholders;

                  (l)      Throughout the five-year period ending on the date of
         the Closing, each Current Fund will have conducted its historic
         business within the meaning of Section 1.368-1(d) of the Income Tax
         Regulations under the Code in a substantially unchanged manner;

                  (m)      The fair market value of the Assets of each Current
         Fund transferred to the corresponding New Fund will equal or exceed the
         sum of the Liabilities assumed by the

                                      AP-6



         New Fund plus the amount of Liabilities, if any, to which the
         transferred Assets are subject; and

                  (n)      The total adjusted basis of the Assets of each
         Current Fund transferred to the corresponding New Fund will equal or
         exceed the sum of the Liabilities assumed by the New Fund plus the
         amount of Liabilities, if any, to which the transferred assets are
         subject.

         4.2      The Trust represents and warrants on its own behalf and on
behalf of each New Fund as follows:

                  (a)      The Trust is a statutory trust duly organized,
         validly existing, and in good standing under the laws of the State of
         Delaware, and its Certificate of Trust has been duly filed in the
         office of the Secretary of State of Delaware;

                  (b)      The Trust is duly registered as an open-end
         management investment company under the 1940 Act. At the Effective
         Time, the New Fund Shares to be issued pursuant to Section 2.1 of this
         Agreement shall be duly registered under the Securities Act of 1933 by
         a Registration Statement filed with the SEC;

                  (c)      At the Effective Time, each New Fund will be a duly
         established and designated series of the Trust;

                  (d)      No New Fund has commenced operations nor will it
         commence operations until after the Closing;

                  (e)      Prior to the Effective Time, there will be no issued
         and outstanding shares in any New Fund or any other securities issued
         by the Trust on behalf of any New Fund, except as provided in Section
         5.2;

                  (f)      No consideration other than New Fund Shares (and each
         New Fund's assumption of the Liabilities) will be issued in exchange
         for the Assets in the Reorganization;

                  (g)      The New Fund Shares to be issued and delivered to
         each corresponding Current Fund hereunder will, at the Effective Time,
         have been duly authorized and, when issued and delivered as provided
         herein, will be duly and validly issued and outstanding shares of the
         New Fund, fully paid and nonassessable;

                  (h)      Each New Fund will be a "fund" as defined in Section
         851(g)(2) of the Code and will meet all the requirements to qualify for
         treatment as a RIC for its taxable year in which the Reorganization
         occurs;

                  (i)      The Trust, on behalf of the New Funds, has no plan or
         intention to issue additional New Fund Shares following the
         Reorganization except for shares issued in the ordinary course of its
         business as an open-end investment company; nor does the Trust, on
         behalf of the New Funds, have any plan or intention to redeem or
         otherwise reacquire any New Fund Shares issued pursuant to the
         Reorganization, other than in the ordinary

                                      AP-7



         course of such business or to the extent necessary to comply with its
         legal obligation under Section 22(e) of the 1940 Act;

                  (j)      Each New Fund will actively continue the
         corresponding Current Fund's business in substantially the same manner
         that the Current Fund conducted that business immediately before the
         Reorganization; and no New Fund has any plan or intention to sell or
         otherwise dispose of any of the Assets, except for dispositions made in
         the ordinary course of its business or dispositions necessary to
         maintain its qualification as a RIC, although in the ordinary course of
         its business the New Fund will continuously review its investment
         portfolio (as each Current Fund did before the Reorganization) to
         determine whether to retain or dispose of particular stocks or
         securities, including those included in the Assets, provided, however
         that this Section 4.2(j) shall not preclude any of the combinations of
         funds set forth on Schedule C to this Agreement; and

                  (k)      There is no plan or intention for any of the New
         Funds to be dissolved or merged into another corporation or statutory
         trust or "fund" thereof (within the meaning of Section 851(g)(2) of the
         Code) following the Reorganization, provided, however that this Section
         4.2(k) shall not preclude any of the combinations of Funds set forth on
         Schedule C.

         4.3      Each of the Company and the Trust, on its own behalf and on
behalf of each Current Fund or each New Fund, as appropriate, represents and
warrants as follows:

                  (a)      The fair market value of the New Fund Shares of each
         New Fund received by each Shareholder will be equal to the fair market
         value of the Current Fund Shares of the corresponding Current Fund
         surrendered in exchange therefor;

                  (b)      Immediately following consummation of the
         Reorganization, the Shareholders will own all the New Fund Shares of
         each New Fund and will own such shares solely by reason of their
         ownership of the Current Fund Shares of the corresponding Current Fund
         immediately before the Reorganization;

                  (c)      The Shareholders will pay their own expenses, if any,
         incurred in connection with the Reorganization;

                  (d)      There is no intercompany indebtedness between a
         Current Fund and a New Fund that was issued or acquired, or will be
         settled, at a discount; and

                  (e)      Immediately following consummation of the
         Reorganization, each New Fund will hold the same assets, except for
         assets distributed to shareholders in the course of its business as a
         RIC and assets used to pay expenses incurred in connection with the
         Reorganization, and be subject to the same liabilities that the
         corresponding Current Fund held or was subject to immediately prior to
         the Reorganization. Assets used to pay (i) expenses, (ii) all
         redemptions (other than redemptions at the usual rate and frequency of
         the Current Fund as a series of an open-end investment company), and
         (iii) distributions (other than regular, normal distributions), made by
         a Current Fund after the date of this Agreement will, in the aggregate,
         constitute less than one percent (1%) of its net assets.

                                      AP-8



5.       COVENANTS.

         5.1      As soon as practicable after the date of this Agreement, the
Company shall call a meeting of its shareholders (the "Shareholders Meeting") to
consider and act on this Agreement and, in connection therewith, the sale of all
of the Company's assets and the dissolution of the Company as a Maryland
corporation. The Board of Directors of the Company shall recommend that
shareholders approve this Agreement and, in connection therewith, sale of all of
the Company's assets and the dissolution of the Company as a Maryland
corporation. Approval by shareholders of this Agreement will authorize the
Company, and the Company hereby agrees, to vote on the matters referred to in
Sections 5.2 and 5.3.

         5.2      Prior to the Closing, the Company shall acquire one New Fund
Share in each New Fund Class of each New Fund for the purpose of enabling the
Company to elect the Company's directors as the Trust's trustees (to serve
without limit in time, except as they may resign or be removed by action of the
Trust's trustees or shareholders), to ratify the selection of the Trust's
independent accountants, and to vote on the matters referred to in Section 5.3.

         5.3      Immediately prior to the Closing, the Trust (on its own behalf
and with respect to each New Fund or each New Fund Class, as appropriate) shall
enter into a Master Investment Advisory Agreement, a Master Sub-Advisory
Agreement, if applicable, a Master Administrative Services Agreement, Master
Distribution Agreements, a Custodian Agreement, and a Transfer Agency and
Servicing Agreement; shall adopt plans of distribution pursuant to Rule 12b-l of
the 1940 Act, a multiple class plan pursuant to Rule 18f-3 of the 1940 Act; and
shall enter into or adopt, as appropriate, such other agreements and plans as
are necessary for each New Fund's operation as a series of an open-end
investment company. Each such agreement and plan shall have been approved by the
Trust's trustees and, to the extent required by law, by such of those trustees
who are not "interested persons" of the Trust (as defined in the 1940 Act) and
by the Company as the sole shareholder of each New Fund.

         5.4      The Company or the Trust, as appropriate, shall file with the
SEC one or more post-effective amendments to the Company's Registration
Statement on Form N-lA under the Securities Act of 1933, as amended, and the
1940 Act, as amended (the "Registration Statement"), which (i) will contain such
amendments to such Registration Statement as are determined by the Company to be
necessary and appropriate to effect the Reorganization and (ii) will register
the New Fund Shares to be issued pursuant to Section 2.1 of this Agreement, and
shall use its best efforts to have such post-effective amendment or amendments
to the Registration Statement become effective as of the Closing.

6.       CONDITIONS PRECEDENT.

         The obligations of the Company, on its own behalf and on behalf of each
Current Fund, and the Trust, on its own behalf and on behalf of each New Fund,
will be subject to (a) performance by the other party of all its obligations to
be performed hereunder at or before the Effective Time, (b) all representations
and warranties of the other party contained herein being true and correct in all
material respects as of the date hereof and, except as they may be affected by
the transactions contemplated hereby, as of the Effective Time, with the same
force

                                      AP-9



and effect as if made on and as of the Effective Time, and (c) the further
conditions that, at or before the Effective Time:

         6.1      The shareholders of the Company shall have approved this
Agreement and the transactions contemplated by this Agreement in accordance with
applicable law.

         6.2      All necessary filings shall have been made with the SEC and
state securities authorities, and no order or directive shall have been received
that any other or further action is required to permit the parties to carry out
the transactions contemplated hereby. All consents, orders, and permits of
federal, state, and local regulatory authorities (including the SEC and state
securities authorities) deemed necessary by either the Company or the Trust to
permit consummation, in all material respects, of the transactions contemplated
hereby shall have been obtained, except where failure to obtain such consults,
orders, and permits would not involve a risk of a material adverse effect on the
assets or properties of either a Current Fund or a New Fund, provided that
either the Company or the Trust may for itself waive any of such conditions.

         6.3      Each of the Company and the Trust shall have received an
opinion from Ballard Spahr Andrews & Ingersoll, LLP as to the federal income tax
consequences mentioned below. In rendering such opinion, such counsel may rely
as to factual matters, exclusively and without independent verification, on the
representations made in this Agreement (or in separate letters of representation
that the Company and the Trust shall use their best efforts to deliver to such
counsel) and the certificates delivered pursuant to Section 3.4. Such opinion
shall be substantially to the effect that, based on the facts and assumptions
stated therein and conditioned on consummation of the Reorganization in
accordance with this Agreement, for federal income tax purposes:

                  (a)      The Reorganization will constitute a reorganization
         within the meaning of section 368(a) of the Code, and each Current Fund
         and each New Fund will be "a party to a reorganization" within the
         meaning of section 368(b) of the Code;

                  (b)      No gain or loss will be recognized to a Current Fund
         on the transfer of its Assets to the corresponding New Fund in exchange
         solely for the New Fund's New Fund Shares and the New Fund's assumption
         of the Current Fund's Liabilities or on the subsequent distribution of
         those New Fund Shares to its Shareholders, in constructive exchange for
         their Current Fund Shares, in liquidation of the Current Fund;

                  (c)      No gain or loss will be recognized to a New Fund on
         its receipt of the corresponding Current Fund's Assets in exchange for
         New Fund Shares and its assumption of the Current Fund's Liabilities;

                  (d)      Each New Fund's basis for the corresponding Current
         Fund's Assets will be the same as the basis thereof in the Current
         Fund's hands immediately before the Reorganization, and the New Fund's
         holding period for those Assets will include the Current Fund's holding
         period therefor;

                  (e)      A Shareholder will recognize no gain or loss on the
         constructive exchange of Current Fund Shares solely for New Fund Shares
         pursuant to the Reorganization; and

                                     AP-10



                  (f)      A Shareholder's basis for the New Fund Shares of each
         New Fund to be received in the Reorganization will be the same as the
         basis for the Current Fund Shares of the corresponding Current Fund to
         be constructively surrendered in exchange for such New Fund Shares, and
         a Shareholder's holding period for such New Fund Shares will include
         its holding period for such Current Fund Shares, provided that such
         Current Fund Shares are held as capital assets by the Shareholder at
         the Effective Time.

         6.4      No stop-order suspending the effectiveness of the Registration
Statement shall have been issued, and no proceeding for that purpose shall have
been initiated or threatened by the SEC (and not withdrawn or terminated).

         At any time prior to the Closing, any of the foregoing conditions
(except those set forth in Sections 6.1 and 6.3) may be waived by the
directors/trustees of either the Company or the Trust if, in their judgment,
such waiver will not have a material adverse effect on the interests of the
Current Fund's Shareholders.

7.       EXPENSES.

         Except as otherwise provided in Section 4.3(c), all expenses incurred
in connection with the transactions contemplated by this Agreement (regardless
of whether they are consummated) will be borne by the parties as they mutually
agree.

8.       ENTIRE AGREEMENT.

         Neither party has made any representation, warranty, or covenant not
set forth herein, and this Agreement constitutes the entire agreement between
the parties.

9.       AMENDMENT.
