<PAGE>

1.   TRANSFER OF ASSETS OF THE ACQUIRED FUND IN EXCHANGE FOR THE ACQUIRING
     FUND SHARES AND ASSUMPTION OF THE ASSUMED LIABILITIES; LIQUIDATION AND
     TERMINATION OF THE ACQUIRED FUND.

     1.1 Subject to the terms and conditions herein set forth and on the basis
of the representations and warranties contained herein, the Acquired Fund will
transfer all of its assets as set forth in Paragraph 1.2 (the "Acquired Assets")
to the Acquiring Fund free and clear of all liens and encumbrances (other than
those arising under the Securities Act of 1933, as amended (the "Securities
Act"), liens for taxes not yet due and contractual restrictions on the transfer
of the Acquired Assets) and the Acquiring Fund agrees in exchange therefor: (i)
to issue to the Acquired Fund the number of Acquiring Fund Shares, including
fractional Acquiring Fund Shares, of each class with an aggregate net asset
value ("NAV") equal to the NAV of the Acquired Fund attributable to the
corresponding class of the Acquired Fund's shares (as described below), as
determined in the manner set forth in Paragraphs 2.1 and 2.2; and (ii) to assume
all of the liabilities and obligations of the Acquired Fund, whether accrued or
contingent, known or unknown, existing at the Closing Date (collectively, the
"Assumed Liabilities"). Such transactions shall take place at the Closing (as
defined in Paragraph 3.1 below). For purposes of this Agreement, the Class A
shares of the Acquired Fund correspond to the Class A shares of the Acquiring
Fund, the Class B shares of the Acquired Fund correspond to the Class B shares
of the Acquiring Fund, the Class C shares of the Acquired Fund correspond to the
Class C shares of the Acquiring Fund and the Class Y shares of the Acquired Fund
correspond to the Class Y shares of the Acquiring Fund, and the term "Acquiring
Fund Shares" should be read to include each such class of shares of the
Acquiring Fund.

     1.2 (a) The Acquired Assets shall consist of all of the Acquired Fund's
property, including, without limitation, all portfolio securities and
instruments, dividends and interest receivables, cash, goodwill, contractual
rights and choses in action of the Acquired Fund or the Acquired Trust in
respect of the Acquired Fund, all other intangible property owned by the

Exchange Commission (the "Commission") promulgated thereunder to the extent such
records pertain to the Acquired Fund.

         (b) The Acquired Fund has provided the Acquiring Fund with a list of
all of the Acquired Fund's securities and other assets as of the date of
execution of this Agreement, and the Acquiring Fund has provided the Acquired
Fund with a copy of the current fundamental investment policies and
restrictions and fair value procedures applicable to the Acquiring Fund. The
Acquired Fund reserves the right to sell any of such securities or other assets
before the Closing Date (except to the extent sales may be limited by
representations of the Acquired Fund contained herein or in the Acquired Fund
Tax Representation Certificate and made in connection with the issuance of the
tax opinion provided for in Paragraph 8.3 hereof) and agrees not to acquire any
portfolio security that is not an eligible investment for, or that would
violate an investment policy or restriction of, the Acquiring Fund.

<PAGE>

     1.3 The Acquired Fund will endeavor to discharge all of its known
liabilities and obligations that are or will become due prior to the Closing.

     1.4 On or as soon after the Closing Date as is conveniently practicable
(the "Liquidation Date"), the Acquired Trust shall liquidate the Acquired Fund
and distribute pro rata to its shareholders of record, determined as of the
close of regular trading on the New York Stock Exchange on the Closing Date (the
"Acquired Fund Shareholders"), the Acquiring Fund Shares received by the
Acquired Fund pursuant to Paragraph 1.1 hereof. Each Acquired Fund Shareholder
shall receive the number of full and fractional Acquiring Fund Shares of the
class corresponding to the class of shares of beneficial interest in the
Acquired Fund (the "Acquired Fund Shares") held by such Acquired Fund
Shareholder that have an aggregate NAV equal to the aggregate NAV of the
Acquired Fund Shares held of record by such Acquired Fund Shareholder on the
Closing Date. Such liquidation and distribution will be accomplished by the
Acquired Trust instructing the Acquiring Trust to transfer 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
established and maintained by the Acquiring Fund's transfer agent in the names
of the Acquired Fund Shareholders and representing the respective pro rata
number of the Acquiring Fund Shares due the Acquired Fund Shareholders. The
Acquired Trust shall promptly provide the Acquiring Trust with evidence of such
liquidation and distribution. All issued and outstanding Acquired Fund Shares
will simultaneously be cancelled on the books of the Acquired Fund, and the
Acquired Fund and the Acquired Trust will be dissolved. The Acquiring Fund shall
not issue certificates representing the Acquiring Fund Shares in connection with
such exchange.

     1.5 Ownership of Acquiring Fund Shares will be shown on the books of the
Acquiring Fund's transfer agent. Any certificates representing ownership of
Acquired Fund Shares that remain outstanding on the Closing Date shall be deemed
to be cancelled and shall no longer evidence ownership of Acquired Fund Shares.

     1.6 Any transfer taxes payable upon issuance of Acquiring Fund Shares in a
name other than the registered holder of the Acquired Fund Shares on the books
of the Acquired Fund as of that time shall, as a condition of such issuance and
transfer, be paid by the person to whom such Acquiring Fund Shares are to be
issued and transferred.

     1.7 Any reporting responsibility of the Acquired Trust with respect to the
Acquired Fund for periods ending on or before the Closing Date, including, but
not limited to, the responsibility for filing of regulatory reports, or other
documents with the Commission, any state securities commissions, and any
federal, state or local tax authorities or any other relevant regulatory
authority, is and shall remain the responsibility of the Acquired Fund.

determined as of the close of regular trading on the New York Stock Exchange
(generally, 4:00 p.m., Eastern time) on the Closing Date (the "Valuation Time").

Declaration of Trust, or By-Laws, and the Acquired Fund's then-current
prospectus and statement of additional information. The Acquiring Fund Adviser

     2.2 The number of shares of each class of Acquiring Fund Shares to be
issued (including fractional shares, if any) in exchange for the Acquired Assets
and the assumption of the Assumed Liabilities shall be determined by the
Acquiring Fund Adviser by dividing the NAV of the Acquired Fund attributable to
each class of the Acquired Fund's shares, as determined in accordance with
Paragraph 2.1, by the NAV of an Acquiring Fund Share of the corresponding class,
as determined in accordance with Paragraph 2.1.

     2.3 The Acquiring Fund and the Acquired Fund shall cause the Acquiring Fund
Adviser to deliver a copy of its valuation report to the other party at Closing

later than three (3) business days preceding the Closing Date. Such portfolio

with respect to the Acquiring Fund and the Acquired Trust Board with respect to
the Acquired Fund), 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.

Act, nor, to the knowledge of the Acquiring Fund, has any affiliated person of

adviser under Section 203(e) of the Investment Advisers Act or Rule 206(4)-4(b)
thereunder or of a broker-dealer under Section 15 of the Exchange Act, or for

Acquiring Trust, on behalf of the Acquiring Fund, to Bingham McCutchen LLP at
the Closing pursuant to Paragraph 6.3 (the "Acquiring Fund Tax Representation
Certificate") will not on the Closing Date contain any untrue statement of a

therein not misleading.

by the Acquiring Fund, followed by the distribution by the Acquired Fund, in
complete liquidation of the Acquired Fund, of Acquiring Fund Shares to the

carryforward, for its taxable year ending on the Closing Date.
