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

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

1.1. Subject to the requisite approval of the Acquired Portfolio shareholders and the other terms and conditions herein set forth and on the basis of the representations and warranties contained herein, the Acquired Portfolio agrees to transfer all of the Acquired Portfolio’s assets, as set forth in paragraph 1.2, to the Acquiring Portfolio, and the Acquiring Portfolio agrees in exchange therefor: (i) to deliver to the Acquired Portfolio the number of full and fractional Class I and Class S Acquiring Portfolio Shares determined by dividing the value of the Acquired Portfolio’s net assets with respect to each class, 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 Portfolio Share of the same class, computed in the manner and as of the time and date set forth in paragraph 2.2; (ii) to deliver to the Acquired Portfolio the number of full and fractional Class S2 Acquiring Portfolio Shares determined by dividing the value of the Acquired Portfolio’s net assets with respect to Adviser Class (“Class A”) shares, 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 Portfolio Share of Class S2, computed in the manner and as of the time and date set forth in paragraph 2.2; and (iii) to assume the liabilities of the Acquired Portfolio, as set forth in paragraph 1.3. Such transactions shall take place at the closing provided for in paragraph 3.1 (the “Closing”).

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

1.3. The Acquired Portfolio will endeavor to discharge all of its known liabilities and obligations prior to the Closing Date. The Acquiring Portfolio shall assume the liabilities of the Acquired Portfolio set forth in the Acquired Portfolio’s Statement of Assets and Liabilities as of the Closing Date delivered by the Company, on behalf of the Acquired Portfolio, to the Trust, on behalf of the Acquiring Portfolio, pursuant to paragraph 7.2 hereof. On or as soon as practicable prior to the Closing Date, the Acquired Portfolio 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 theClosing Date.

1.4. Immediately after the transfer of assets provided for in paragraph 1.1, the Acquired Portfolio will: (i) distribute to the Acquired Portfolio’s shareholders of record with respect to its Class I and Class S shares, determined as of immediately after the close of business on the Closing Date, on a pro rata basis within that class, the Acquiring Portfolio Shares of the same class received by the Acquired Portfolio pursuant to paragraph 1.1; (ii) distribute to the Acquired Portfolio’s shareholders of record with respect to Class A shares, determined as of immediately after the close of business on the Closing Date, on a pro rata basis within that class, the Acquiring Portfolio Shares of Class S2 received by the Acquired Portfolio pursuant to paragraph 1.1; and (iii) completely liquidate. Such distribution and liquidation will be accomplished, with respect to each Class of the Acquired Portfolio’s shares, by the transfer of the Acquiring Portfolio Shares then credited to the account of the Acquired Portfolio on the books of the Acquiring Portfolio to open accounts on the share records of the Acquiring Portfolio in the names of Class A, Class I and Class S Acquired Portfolio’s shareholders, determined as of immediately after the close of business on the Closing Date (“Acquired Portfolio Shareholders”). The aggregate net asset value of Class I and Class S Acquiring Portfolio Shares to be so credited to Class I and Class S Acquired Portfolio Shareholders shall, with respect to each class, be equal to the aggregate net asset value of the Acquired Portfolio shares of that same class owned by such shareholders on the Closing Date. The aggregate net asset value of Class S2 Acquiring Portfolio Shares to be so credited to Class A Acquired Portfolio Shareholders shall be equal to the aggregate net asset value of the Acquired Portfolio shares of Class A owned by such shareholders on the Closing Date. All issued and outstanding Class I and Class S Acquired Portfolio shares will simultaneously be canceled on the books of the Acquired Portfolio, although share certificates representing interests in Class I and Class S shares of the Acquired Portfolio will represent a number of the class of Acquiring Portfolio Shares after the Closing Date, as determined in accordance with Section 2.3. All issued and outstanding Class A shares of the Acquired Portfolio will simultaneously be canceled on the books of the Acquired Portfolio, although share certificates representing interests in Class A Acquired Portfolio Shares will represent a number Class S2 Acquiring Portfolio Shares after the Closing Date, as determined in accordance with Section 2.3. The Acquiring Portfolio shall not issue certificates representing the Class I, Class S and Class S2 Acquiring Portfolio Shares in connection with such exchange.

1.5. Ownership of Acquiring Portfolio Shares will be shown on the books of the Acquiring Portfolio’s transfer agent, as defined in paragraph 3.3.

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

2.3.
