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 A shares and Class I 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 FCST 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:

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 known or unknown class action claims outstanding as of the Effective Time that become payable after the Effective Time, any deferred or prepaid expenses shown as an asset on the books of the Acquired Fund at the Effective Time, books and records 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 FCST on behalf of the Acquired Fund to prepare and file Tax Returns pursuant to paragraph 5.14 of this Agreement.

1.3.Liabilities of the Acquired Fund.

(“JPMorgan”), which serves as the custodian for the Acquiring Fund, who have primary responsibility for the safekeeping of the assets of the Acquiring Fund.

Fiera Capital and the Acquired Fund shall use their best efforts to deliver to the Acquiring Fund all dividends, interest, proceeds from any class action claims, other payments or any other form of distribution made on or after the Closing Date to the Acquired Fund that have not been delivered by the Acquired Fund to the Acquiring Fund.

3.3.Share Records. FCST shall direct UMB Fund Services, Inc. (“UMB Fund Services”), in its capacity as transfer agent for the Acquired Fund (the “Transfer Agent”), to deliver to MainStay Funds at the Closing a certificate of an authorized officer of UMB Fund Services stating that its records contain the names and addresses of the Acquired Fund Shareholders and the number and percentage ownership of outstanding Acquired Fund Shares owned by each such Acquired Fund Shareholder immediately prior to the Closing. An officer of the Acquiring Fund shall issue and deliver to the Secretary of the Acquired Fund prior to the Effective Time a confirmation evidencing that the appropriate number of Acquiring Fund Shares will be credited to the Acquired Fund at the Effective Time, or provide other evidence reasonably satisfactory to the Acquired Fund as of the Effective Time that such Acquiring Fund Shares have been credited to the Acquired Fund’s accounts on the books of the Acquiring Fund.

3.4.Postponement of Effective Time. In the event that, at the Effective Time, (a) the NYSE or another primary trading market for portfolio securities of the Acquiring Fund or the Acquired Fund (each, an “Exchange”) 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 Trustees of FCST or the Board of Trustees of MainStay Funds, accurate appraisal of the value of the assets of the Acquired Fund or the Acquiring Fund, respectively, is impracticable, the Effective Time shall be postponed until the first business day after the day when trading shall have been fully resumed and reporting shall have been restored.
