   NOW, THEREFORE, in consideration of the promises and of the covenants and
agreements hereinafter set forth, the parties hereto covenant and agree as
follows:


1. TRANSFER OF ASSETS OF THE ACQUIRED FUND TO THE ACQUIRING FUND IN EXCHANGE FOR
   THE ACQUIRING FUND SHARES, THE ASSUMPTION OF ALL ACQUIRED FUND LIABILITIES
   AND THE LIQUIDATION OF THE ACQUIRED FUND

   1.1  Subject to the requisite approval of the Acquired Fund shareholders and
the other terms and conditions herein set forth and on the basis of the
representations and warranties contained herein, the Acquired Fund agrees to
transfer all of the Acquired Fund's assets, as set forth in paragraph 1.2, to
the Acquiring Fund, and the Acquiring Fund agrees in exchange therefor: (i) to
deliver to the Acquired Fund the number of full and fractional Acquiring Fund
Shares determined by dividing the value of the Acquired Fund's net assets
computed in the manner and as of the time and date set forth in paragraph 2.1,
by the net asset value of one Acquiring Fund Share, computed in the manner and
as of the time and date set forth in paragraph 2.2; and (ii) to assume all
liabilities of the Acquired Fund, as set forth in paragraph 1.3. Such
transactions shall take place at the Closing.

   1.2  The assets of the Acquired Fund to be acquired by the Acquiring Fund
shall consist of all assets and property, including, without limitation, all
cash, securities (including loans as defined in the prospectus for the Acquired
Fund), commodities and futures interests and dividends or interests receivable,
that are owned by the Acquired Fund, and any deferred or prepaid expenses shown
as an asset on the books of the Acquired Fund (collectively, "Assets"), on the
closing date provided for in paragraph 3.1 (the "Closing Date").

   1.3  The Acquired Fund will endeavor to discharge all of its known
liabilities and obligations prior to the Closing Date. The Acquiring Fund shall
assume all of the liabilities of the Acquired Fund, whether accrued or
contingent, known or unknown, existing at the Valuation Date (as defined in
paragraph 2.1) (collectively, "Liabilities"). On or as soon as practicable prior
to the Closing Date, the Acquired Fund will declare and pay to its shareholders
of record one or more dividends and/or other distributions so that it will have
distributed substantially all (and in no event less than 98%) of its investment
company taxable income (computed without regard to any deduction for dividends
paid) and realized net capital gain, if any, for the current taxable year
through the Closing Date.

   1.4  Immediately after the transfer of assets provided for in paragraph 1.1,
the Acquired Fund will distribute to the Acquired Fund's shareholders of record,
determined immediately after the close of business on the Closing Date (the
"Acquired Fund Shareholders"), on a pro rata basis, the Acquiring Fund Shares
received by the Acquired Fund pursuant to paragraph 1.1, and upon such
distribution will completely liquidate. Such distribution and liquidation will
be accomplished, with respect to the Acquired Fund's shares, by the transfer of
the Acquiring Fund Shares then credited to the account of the Acquired Fund on
the books of the Acquiring Fund to open accounts on the share records of the
Acquiring Fund in the names of the Acquired Fund Shareholders. The aggregate net
asset value of Acquiring Fund Shares to be so credited to the Acquired Fund
Shareholders shall be equal to the aggregate net asset value of the Acquired
Fund shares owned by such shareholders on the Closing Date. All issued and
outstanding shares of the Acquired Fund will simultaneously be canceled on the
books of the Acquired Fund.  The Acquiring Fund shall not issue certificates
representing the Acquiring Fund Shares in connection with such exchange.  The
Acquired Fund will, thereafter, dissolve.

   1.5  Ownership of Acquiring Fund Shares will be shown on the books of the
Acquiring Fund's transfer agent.

   1.6  Any reporting responsibility of the Acquired Fund including, but not
limited to, the responsibility for filing of regulatory reports, tax returns, or
other documents with the Securities and Exchange Commission (the

                                       2


"Commission"), any state securities commission, and any federal, state or local
tax authorities or any other relevant regulatory authority, is and shall remain
the responsibility of the Acquired Fund.

   1.7  Shares issued and distributions made under the above provisions are
subject to provisions of Title 3, Subtitle 2 of the Maryland General Corporation
Law relating to dissenting shareholders, as applicable.

2. VALUATION

   2.1  The value of the Assets shall be the value computed immediately after
the close of business of the New York Stock Exchange and after the declaration
of any dividends on the Closing Date (such time and date being hereinafter
called the "Valuation Date"), using the valuation procedures in the then-current
prospectus and statement of additional information with respect to the Acquiring
Fund, and valuation procedures established by the Acquiring Fund's Board of
Directors.

   2.2  The net asset value of the Acquiring Fund Shares shall be the net asset
value per share of the Acquiring Fund's outstanding shares computed as of the
Valuation Date, using the valuation procedures set forth in the Acquiring Fund's
then-current prospectus and statement of additional information with respect to
the Acquiring Fund, and valuation procedures established by the Acquiring Fund's
Board of Directors.

   2.3  The number of the Acquiring Fund Shares to be issued (including
fractional shares, if any) in exchange for the Acquired Fund's assets shall be
determined by dividing the value of the net assets of the Acquired Fund,
determined using the same valuation procedures referred to in paragraph 2.1, by
the net asset value of an Acquiring Fund Share, determined in accordance with
paragraph 2.2.

   2.4  All computations of value shall be made by the Acquired Fund's
designated record keeping agent and shall be subject to confirmation by
Acquiring Fund's record keeping agent and by each fund's respective independent
accountants.

3. CLOSING AND CLOSING DATE

certificate of an authorized officer stating that (i) the Assets shall have been
delivered in proper form to the Acquiring Fund within two business days prior to
or on the Closing Date, and (ii) all necessary taxes in connection with the

transfer stamps, if any, have been paid or provision for payment has been made.

written instrument shall be presented for examination by the Custodian to the
custodian for the Acquiring Fund no later than five business days preceding the
Closing Date, and shall be transferred and delivered by the Acquired Fund as of
the Closing Date for the account of the Acquiring Fund duly endorsed in proper

under the 1940 Act in which the Acquired Fund's Assets are

                                       3

depositories. The cash to be transferred by the Acquired Fund shall be delivered
by wire transfer of federal funds on the Closing Date.

be credited on the Closing Date to the Secretary of the Acquiring Fund, or
provide evidence satisfactory to the Acquired Fund that such Acquiring Fund
Shares have been credited to the Acquired Fund's account on the books of the
Acquiring Fund.  At the Closing each party shall deliver to the other such bills
of sale, checks, assignments, share certificates, if any, receipts or other
documents as such other party or its counsel may reasonably request.

   3.4  In the event that on the Valuation Date (a) the primary trading market
for portfolio securities of the Acquiring Fund or the Acquired Fund shall be
closed to trading or trading thereupon shall be restricted, or (b) trading or
the reporting of trading on such exchange or elsewhere shall be disrupted so
that, in the judgment of the Board of Directors of the Acquired Fund and the
Board of Directors of the Acquiring Fund, accurate appraisal of the value of the
net assets of the Acquired Fund or the Acquiring Fund, respectively, is
impracticable, the Closing Date shall be postponed until the first business day
after the day when trading shall have been fully resumed and reporting shall
have been restored.

   3.5  The Acquired Fund and the Acquiring Fund shall file Articles of Transfer
