The reorganization will consist of the transfer of all of the assets of the Acquired Fund to the Acquiring Fund in exchange solely for Class C, Class I and Class Z shares of beneficial interest of the Acquiring Fund (the “Acquiring Fund Shares”), the assumption by the Acquiring Fund of all liabilities of the Acquired Fund, and the distribution, upon the Closing Date (as defined in paragraph 3.1), of the Acquiring Fund Shares to the shareholders of the Acquired Fund in complete liquidation of the Acquired Fund, all upon the terms and conditions hereinafter set forth in this Agreement (the “Reorganization”).

The Board of Trustees of AMT has determined, with respect to the Acquired Fund, that (1) participation in the Reorganization is in the best interests of the Acquired Fund and its shareholders, and (2) the interests of the existing shareholders of the Acquired Fund would not be diluted as a result of the Reorganization. The Board of Trustees of MainStay Funds has determined, with respect to the Acquiring Fund, that (1) participation in the Reorganization is in the best interests of the Acquiring Fund and its shareholders, and (2) the interests of the existing shareholders of the Acquiring Fund would not be diluted as a result of the Reorganization.

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

ARTICLE I

THE REORGANIZATION AND FUND TRANSACTIONS

1.1. The Reorganization. Subject to the requisite approval of the Acquired Fund’s shareholders and the other terms and conditions herein set forth and on the basis of the representations and warranties contained herein, at the Effective Time (as defined in paragraph 2.4), AMT shall assign, deliver and otherwise transfer the Assets (as defined in paragraph 1.2) of the Acquired Fund to MainStay Funds on behalf of the Acquiring Fund. In consideration of the foregoing, at the Effective Time, MainStay Funds shall, on behalf of the Acquiring Fund, deliver to AMT on behalf of the Acquired Fund, full and fractional Acquiring Fund Shares (to the third decimal place), and MainStay Funds shall assume the Liabilities (as defined in paragraph 1.3) of the Acquired Fund on behalf of the Acquiring Fund. The number of Acquiring Fund Shares to be delivered shall be determined as set forth in paragraph 2.3.

1.2. Assets of the Acquired Fund. The assets of the Acquired Fund to be transferred to the Acquiring Fund shall consist of all assets and property, including, without limitation, all cash, cash equivalents, securities, receivables (including securities, interests and dividends receivable), commodities and futures interests, rights to register shares under applicable securities laws, all rights of the Acquired Fund, any deferred or prepaid expenses shown as an asset on the books of the Acquired Fund at the Effective Time, books and records, any deferred tax benefit and any other property owned by the Acquired Fund at the Effective Time (collectively, the “Assets”). Notwithstanding the foregoing, copies of the applicable books and records may be retained as required by applicable law or as necessary for the Acquired Fund or AIM on behalf of the Acquired Fund to prepare and file tax returns pursuant to paragraph 5.13 of this Agreement.

1.3. Liabilities of the Acquired Fund. The Acquired Fund will use commercially reasonable efforts to discharge its known liabilities and obligations prior to the Effective Time, other than liabilities and obligations necessary or appropriate for the Acquired Fund’s normal investment operations that are incurred in the ordinary course of business consistent with past practice. The Acquiring Fund shall assume all liabilities, obligations and debts of the Acquired Fund, whether known or unknown,

absolute or contingent, accrued or unaccrued, existing at the Effective Time, and whether or not specifically referred to in this Agreement (collectively, the “Liabilities”).

1.4. Distribution of Acquiring Fund Shares. At the Closing (as defined below) (or as soon thereafter as is reasonably practicable), AMT, on behalf of the Acquired Fund, will distribute the Acquiring Fund Shares received from MainStay Funds pursuant to paragraph 1.1, pro rata to the record holders of the shares of the Acquired Fund determined as of the Effective Time (the “Acquired Fund Shareholders”) in complete liquidation of the Acquired Fund. Holders of Class A shares of the Acquired Fund will receive Class Z shares of the Acquiring Fund; holders of Class C shares of the Acquired Fund will receive Class C shares of the Acquiring Fund; holders of Class F shares of the Acquired Fund will receive Class I shares of the Acquiring Fund; and holders of Class Y shares of the Acquired Fund will receive Class I shares of the Acquiring Fund. Such distribution and liquidation will be accomplished 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 the Acquiring Fund Shares to be so credited to Acquired Fund Shareholders shall be equal to the aggregate net asset value of the then outstanding shares of beneficial interest of the Acquired Fund (the “Acquired Fund Shares”) owned by Acquired Fund Shareholders at the Effective Time. All issued and outstanding Acquired Fund Shares will simultaneously be redeemed and 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.

(d) The current prospectus, statement of additional information, shareholder reports, marketing and other related materials of the Acquired Fund and each prospectus and statement of additional information of the Acquired Fund used at all times prior to the date of this Agreement conform or conformed at the time of its use in all material respects to the applicable requirements of the 1933 Act and the 1940 Act and the rules and regulations of the Commission thereunder and does not or did not at the time of its use include any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not materially misleading.

(e) At the Effective Time, AMT, on behalf of the Acquired Fund, will have good and marketable title to the Assets and full right, power, and authority to sell, assign, transfer and deliver such Assets hereunder free of any liens or other encumbrances, and upon delivery and payment for such Assets, MainStay Funds, on behalf of the Acquiring Fund, will acquire good and marketable title thereto, subject to no restrictions on the full transfer thereof, including such restrictions as might arise under the 1933 Act; provided, however, that certain Assets may be pledged against the Acquired Fund’s investment contracts, including options, futures, forward contracts and other similar instruments, in accordance with the terms of such contracts.

(f) AMT, on behalf of the Acquired Fund, is not engaged currently, and the execution, delivery and performance of this Agreement will not result, in (i) a material violation of Massachusetts law or of its Declaration of Trust or By-Laws, or a material breach of any agreement, indenture, instrument, contract, lease or other undertaking to which AMT, on behalf of the Acquired Fund, is a party or by which it is bound, including the Acquired Fund’s investment advisory agreement with AIM, which has been properly approved pursuant to Section 15(c) of the 1940 Act, or (ii) the acceleration of any material obligation, or the imposition of any material penalty, under any agreement, indenture, instrument, contract, lease, judgment or decree to which AMT, on behalf of the Acquired Fund, is a party or by which it is bound.

(2) No gain or loss will be recognized by the Acquired Fund upon the transfer of the Acquired Fund’s Assets to the Acquiring Fund solely in exchange for Acquiring Fund Shares and the assumption by the Acquiring Fund of the Acquired Fund’s Liabilities, or upon the distribution (whether actual or constructive) by the Acquired Fund of such Acquiring Fund Shares to the Acquired Fund Shareholders in liquidation, except that the Acquired Fund may be required to recognize gain or loss with respect to: (A) contracts described in Section 1256(b) of the Code; (B) stock in a passive foreign investment company, as defined in Section 1297(a) of the Code; or (C) any other gain or loss required to be recognized upon the termination of a position, or upon the transfer of such asset regardless of whether such a transfer would otherwise be a nontaxable transaction under the Code.

(3) No gain or loss will be recognized by the Acquiring Fund upon the receipt of the Acquired Fund’s Assets solely in exchange for Acquiring Fund Shares and the assumption by the Acquiring Fund of the Acquired Fund’s Liabilities.

(4) No gain or loss will be recognized by the Acquired Fund Shareholders upon the distribution to them by the Acquired Fund of the Acquiring Fund Shares solely in exchange for their Acquired Fund Shares as part of the Reorganization.

(5) The basis of the Acquiring Fund Shares received by each Acquired Fund Shareholder in the Reorganization will be the same as the basis of the shareholder’s Acquired Fund Shares exchanged therefor.

(6) The basis of the Acquired Fund’s Assets received by the Acquiring Fund in the Reorganization will be the same as the basis of the Acquired Fund’s Assets in the hands of the Acquired Fund immediately prior to the transfer, adjusted for any gain or loss required to be recognized in paragraph (2) above.

(7) The holding period for the Acquiring Fund Shares received by each Acquired Fund Shareholder in the Reorganization will include the period for which the shareholder held the Acquired Fund Shares exchanged therefor, provided that the shareholder held such Acquired Fund Shares as a capital asset at the time of the exchange.

(8) The holding period of the Acquired Fund’s Assets in the hands of the Acquiring Fund will include the period for which the Acquired Fund’s Assets were held by the Acquired Fund (except where investment activities of the Acquiring Fund have the effect of reducing or eliminating a holding period with respect to an Asset and except for any asset with respect to which gain or loss is required to be recognized as described in paragraph (2) above).

(9) The Reorganization will not result in the termination of the Acquired Fund’s taxable year, and the Acquiring Fund will succeed to and take into account those tax attributes of the Acquired Fund that are described in Section 381(c) of the Code, subject to the conditions and limitations specified in the Code, the regulations thereunder, and existing court decisions and published interpretations of the Code and regulations.

The delivery of such opinion is conditioned upon receipt by Dechert LLP of representations requested of AMT and Mainstay Funds on behalf of the Acquired Fund and the Acquiring Fund, respectively.
