1.1 THE TRANSACTIONS. Subject to the terms and conditions herein set forth and on the basis of the representations and warranties contained herein, the Selling Fund agrees to transfer all of the Selling Fund’s assets as set forth in paragraph 1.2 to the Acquiring Fund, subject to all of the Selling Fund’s liabilities as set forth in paragraph 1.3. The Acquiring Fund agrees to acquire those assets and, as consideration therefor, to assume such liabilities and to deliver to the Selling Fund the number of Merger Shares, including fractional Merger Shares, computed in the manner and as of the time and date set forth in Article II. Such transactions shall take place at the Closing (as defined in paragraph 3.1).

1.2 ASSETS TO BE ACQUIRED. The assets of the Selling Fund to be acquired by the Acquiring Fund shall consist of all assets, including, without limitation, all cash, securities, commodities, interests in derivative instruments, and dividends or interest or other receivables, that are owned by the Selling Fund and any prepaid expenses, other than unamortized reorganizational expenses, shown as an asset on the books of the Selling Fund as of the Closing (such assets, the “Acquired Assets”).

1.3 LIABILITIES TO BE ASSUMED. The Acquiring Fund shall assume all of the Selling Fund’s liabilities, debts, obligations, and duties as of the Valuation Date (as defined in paragraph 2.1) (such liabilities, the “Assumed Liabilities”). Each Acquiring Fund agrees that all rights to indemnification and all limitations of liability existing in favor of the corresponding Selling Fund’s current and former trustees and officers, acting in their capacities as such, shall survive each Reorganization and shall continue in full force and effect, without any amendment thereto. Each Acquiring Fund agrees that such rights and limitations may be asserted against the Acquiring Fund and its successors and assigns.

1.4 DISTRIBUTION. On or as soon after the Closing Date (as defined in paragraph 3.1) as is conveniently practicable (the “Liquidation Date”): (a) the Selling Fund will liquidate and distribute pro rata to the Selling Fund’s shareholders of record, determined as of the close of business on the Valuation Date (the “Selling Fund Shareholders”), the Merger Shares received by the Selling Fund pursuant to paragraph 1.1 above; and (b) the Selling Fund will thereupon proceed to terminate as set forth in paragraph 1.6 below. Such liquidation and distribution will be accomplished by the transfer of the Merger Shares then credited to the account of the Selling Fund on the books of the Acquiring Fund to open accounts on the share records of the Acquiring Fund in the names of the Selling Fund Shareholders and representing the respective pro rata number of the Merger Shares due such shareholders. All issued and outstanding shares of the Selling Fund will simultaneously be canceled on the books of the Selling Fund. The Merger Shares distributed to Selling Fund Shareholders will be of the share class or share classes of the Acquiring Fund identified in Exhibit B as corresponding to the share class or share classes held by such Selling Fund Shareholder in the Selling Fund immediately prior to the Closing (hereinafter, the “corresponding share class”). The Acquiring Fund shall not issue certificates representing the Merger Shares in connection with such distribution.

1.5 OWNERSHIP OF SHARES. Ownership of the Merger Shares will be shown on the books of State Street Bank and Trust Company (“State Street”), the Acquiring Fund’s transfer agent.

1.6 TERMINATION. The Selling Fund shall be terminated promptly following the Closing Date and the making of all distributions pursuant to paragraph 1.4, and shall cease to operate as a series of an investment company registered under the Investment Company Act of 1940, as amended (the “1940 Act”). Any reporting responsibility of the Selling Fund is and shall remain the responsibility of the Selling Fund up to and including the Closing Date and thereafter. The Selling Fund agrees that the liquidation and dissolution of the Selling Fund will be effected in the manner provided in the MassMutual Select Funds Declaration (defined below), as amended, in accordance with applicable law and that, on and after the Closing Date, the Selling Fund will not conduct any business except in connection with its liquidation and dissolution.

ARTICLE II

VALUATION

2.1 VALUATION OF ASSETS AND LIABILITIES. The value of the Selling Fund’s assets to be acquired by the Acquiring Fund hereunder shall be the value of such assets, less the value of the Assumed Liabilities attributable to the shares of the Selling Fund, computed as of the

close of regular trading on the New York Stock Exchange on the business day immediately preceding the Closing Date (such time and date, the “Valuation Date”), using the valuation procedures of the Acquiring Fund in a manner consistent with the Acquiring Fund’s then-current prospectus and statement of additional information and established by the Acquiring Trust’s Board of Trustees for determining net asset value.

2.2 VALUATION OF SHARES. The net asset value per share of the Merger Shares shall be the net asset value per share computed as of the close of regular trading on the New York Stock Exchange on the Valuation Date, using the valuation procedures of the Acquiring Fund in a manner consistent with the Acquiring Fund’s then-current prospectus and statement of additional information and established by the Acquiring Trust’s Board of Trustees for determining net asset value.

2.3 SHARES TO BE ISSUED. Holders of each class of Selling Fund shares will receive Merger Shares of the corresponding share class of the Acquiring Fund. The number of the Merger Shares to be issued (including fractional shares, if any) in exchange for the Selling Fund’s assets shall be the sum of the amounts determined in respect of each class of the Selling Fund by dividing the net assets of the Selling Fund attributable to that class by the net asset value per share of the corresponding share class of the Acquiring Fund determined in accordance with paragraph 2.2.

ARTICLE III

CLOSING AND CLOSING DATE

3.1 CLOSING DATE. The closing of the transactions contemplated by paragraph 1.1 (the “Closing”) shall take place on or about September 23, 2024 at 7:30 a.m., or such other time and date as the parties may agree (the “Closing Date”). The Closing shall be held at the offices of Ropes & Gray, LLP, or at such other time and/or place or manner (which may include a virtual closing) as the parties may agree.

3.2 EXAMINATION OF PORTFOLIO SECURITIES. The portfolio securities of the Selling Fund shall be made available by the Selling Fund to the custodian for the Acquiring Fund (the “Custodian”), for examination no later than five business days preceding the Valuation Date. On the Closing Date, such portfolio securities and all the Selling Fund’s cash shall be delivered by the Selling Fund to the Custodian for the account of the Acquiring Fund, such portfolio securities to be duly endorsed in proper form for transfer in such manner and condition as to constitute good delivery thereof in accordance with the custom of brokers or, in the case of portfolio securities held in the U.S. Treasury Department’s book-entry system or by the Depository Trust Company, Participants Trust Company or other third party depositories, by transfer to the account of the Custodian in accordance with Rule 17f-4, Rule 17f-5 or Rule 17f-7, as the case may be, under the 1940 Act, and accompanied by all necessary federal and state stock transfer stamps or a check for the appropriate purchase price thereof. The cash delivered shall be in the form of currency or certified or official bank checks, payable to the order of the custodian for the Acquiring Fund.

3.3 EFFECT OF SUSPENSION IN TRADING. In the event that on the Valuation Date (a) the New York Stock Exchange, the U.S. bond markets, or another primary trading market for portfolio securities of the Acquiring Fund or the Selling Fund shall be closed to trading or trading thereon shall be restricted; or (b) trading or the reporting of trading on said Exchange or elsewhere shall be disrupted so that accurate appraisal of the value of the net assets of the Acquiring Fund or the Selling Fund is impracticable, the Valuation Date shall, except as may otherwise be mutually agreed, be postponed until the first business day after the day when trading shall have been fully resumed and reporting shall have been restored.

3.4 TRANSFER AGENT’S CERTIFICATE. At the Closing, State Street, as transfer agent for the Selling Fund, shall deliver a certificate of an authorized officer setting forth from its records the names and addresses of the Selling Fund Shareholders and the number and percentage ownership of outstanding shares owned by each such shareholder, all as of the close of business on the Valuation Date. On the Closing Date, the Acquiring Fund shall issue and deliver or cause State Street to issue and deliver a confirmation to the Selling Fund evidencing the Merger Shares to be credited on the Closing Date to the Selling Fund’s account or provide evidence satisfactory to the Selling Fund that such Merger Shares have been credited to the Selling Fund’s account on the books of the Acquiring Fund. On the Liquidation Date, the Acquiring Fund will provide to the Selling Fund evidence reasonably satisfactory to the Selling Fund that such Acquiring Fund shares have been credited pro rata to open accounts in the names of Selling Fund shareholders as provided in Section 1.4.

3.5 OTHER CERTIFICATES. At the Closing, each party shall deliver to the other such bills of sale, checks, assignments, share certificates, if any, receipts and other documents as such other party or its counsel may reasonably request in connection with the transfer of assets, assumption of liabilities and liquidation contemplated by Section 1.

For the purposes of this subparagraph (n), a decline in the net asset value of the Acquiring Fund shall not constitute a material adverse change, and changes in portfolio securities, changes in the market value of portfolio securities or net redemptions shall be deemed to be in the ordinary course of business.

(s) The issuance of the Merger Shares pursuant to this Agreement will be in compliance with all applicable federal securities laws.

FURTHER CONDITIONS PRECEDENT TO OBLIGATIONS OF THE ACQUIRING FUND AND THE SELLING FUND

If any of the conditions set forth in paragraphs 8.2, 8.3, 8.4, and 8.5 below do not exist on or before the Closing with respect to the Selling Fund or the Acquiring Fund, either party to this Agreement shall, at its option, not be required to consummate the transactions contemplated by this Agreement. The conditions set forth in paragraphs 8.1 and 8.6 below may not be waived by either party to this Agreement, and must be satisfied prior to Closing.

8.1 This Agreement is adopted and the transactions contemplated hereby are approved by the affirmative vote of (i) at least a majority of the Trustees of the Selling Fund (including a majority of those Trustees who are not “interested persons” of the Selling Fund, as defined in Section 2(a)(19) of the 1940 Act) and (ii) at least a majority of the Trustees of the Acquiring Fund (including a majority of those Trustees who are not “interested persons” of the Acquiring Fund, as defined in Section 2(a)(19) of the 1940 Act).

8.2 On the Closing Date, the Commission shall not have issued an unfavorable report under Section 25(b) of the 1940 Act, nor instituted any proceeding seeking to enjoin the consummation of the transactions contemplated by this Agreement under Section 25(c) of the 1940 Act and no action, suit or other proceeding shall be threatened or pending before any court or governmental agency in which it is sought to restrain or prohibit, or obtain damages or other relief in connection with, this Agreement or the transactions contemplated herein.

8.3 All required consents of other parties and all other consents, orders, and permits of federal, state and local regulatory authorities (including those of the Commission and of state Blue Sky and securities authorities, including any necessary “no-action” positions of and exemptive orders from such federal and state authorities) deemed necessary by the Selling Trust, the Selling Fund, the Acquiring Trust or the Acquiring Fund to permit consummation, in all material respects, of the transactions contemplated hereby shall have been obtained, except where failure to obtain any such consent, order or permit would not involve a risk of a material adverse effect on the assets or properties of the Acquiring Fund or the Selling Fund, provided that either party hereto may for itself waive any of such conditions.

8.4 The Registration Statement shall have become effective under the 1933 Act and no stop order suspending the effectiveness thereof shall have been issued and, to the best knowledge of the parties hereto, no investigation or proceeding for that purpose shall have been instituted or be pending, threatened or contemplated under the 1933 Act.

8.5 There is no material litigation pending with respect to the matters contemplated by this Agreement.

8.6 For each Acquiring Fund and the corresponding Selling Fund, the parties hereto shall have received on the Closing Date an opinion from Ropes & Gray LLP, counsel to the Funds, dated as of the Closing Date, which opinion will be based on certain factual representations made by officers of each Trust and certain customary assumptions, in form and substance reasonably satisfactory to the parties, substantially to the effect that, on the basis of the existing provisions of the Code, Treasury regulations promulgated thereunder, current administrative rules and court decisions, while the matter is not free from doubt, generally for federal income tax purposes:

(a) The transfer of all of the Acquired Assets in exchange for the Merger Shares and the assumption by the Acquiring Fund of all of the Assumed Liabilities followed by the distribution of the Merger Shares pro rata to the Selling Fund Shareholders pursuant to this Agreement will constitute a “reorganization” within the meaning of Section 368(a) of the Code and the Acquiring Fund and the Selling Fund will each be a “party to a reorganization” within the meaning of Section 368(b) of the Code.

(b) Under Section 1032 of the Code, no gain or loss will be recognized by the Acquiring Fund upon the receipt of the Acquired Assets solely in exchange for the Merger Shares and the assumption by the Acquiring Fund of the Assumed Liabilities.

(c) Under Sections 361 and 357 of the Code, no gain or loss will be recognized by the Selling Fund with respect to the Acquired Assets in connection with the transfer of the Acquired Assets to the Acquiring Fund in exchange for the Merger Shares and the assumption by the Acquiring Fund of the Assumed Liabilities, or with respect to the distribution of the Merger Shares to Selling Fund Shareholders as consideration for their shares of the Selling Fund, except for (A) any gain or loss recognized on (1) “Section 1256 contracts” as defined in Section 1256(b) of the Code or (2) stock in a “passive foreign investment company” as defined in Section 1297(a) of the Code, and (B) any other gain or loss required to be recognized by reason of the Reorganization (1) as a result of the closing, if any, of the tax year of the Selling Fund, (2) upon the termination of a position, or (3) upon the transfer of such asset regardless of whether such a transfer would otherwise be a nontaxable transaction under the Code.

(d) Under Section 354 of the Code, no gain or loss will be recognized by the Selling Fund Shareholders upon their receipt of the Merger Shares solely in exchange for Selling Fund shares.

(e) Under Section 358 of the Code, the aggregate tax basis for the Merger Shares received by each Selling Fund Shareholder will be the same as the aggregate tax basis of the Selling Fund shares held by such shareholder immediately prior to the exchange, and, under Section 1223(1) of the Code, the holding period of the Merger Shares received by each Selling Fund Shareholder will include the period during which the Selling Fund shares exchanged therefor were held by such shareholder (provided the Selling Fund shares were held as capital assets).

(f) Under Section 362(b) of the Code, the tax basis of the Selling Fund assets acquired by the Acquiring Fund will be the same as the tax basis of such assets to the Selling Fund immediately prior to the Reorganization, adjusted for any gain or loss required to be recognized as described in (c) above, and, under Section 1223(2) of the Code, the holding period of the assets of the Selling Fund in the hands of the Acquiring Fund, other than certain assets with respect to which gain or loss is required to be recognized as described in (c) above, will include the period during which those assets were held by the Selling Fund.

(g) The Acquiring Fund will succeed to and take into account the items of the Selling Fund described in Section 381(c) of the Code, subject to the conditions and limitations specified in Sections 381, 382, 383, and 384 of the Code and the Treasury Regulations thereunder.

The opinion will note and distinguish certain published precedent. It is possible that the Internal Revenue Service or a court could disagree with Ropes & Gray LLP’s opinion, which therefore cannot be free from doubt.

Notwithstanding anything herein to the contrary, neither the Selling Fund nor the Acquiring Fund may waive the conditions set forth in this paragraph 8.6.

ARTICLE IX

EXPENSES

9.1 With respect to each Reorganization, each Acquiring Fund will bear the costs of certain reorganization-related administrative processing conducted by the Fund’s custodian in connection with the Reorganization (the “Acquiring Fund Custodian Fee”). All other expenses of the transactions, including without limitation, accounting, legal, and custodial expenses (except for the Acquiring Fund Custodian Fee) contemplated by this Agreement will be allocated among the Selling Funds in accordance with this paragraph, whether incurred before or after the date of this Agreement. Each Selling Fund will bear the direct merger costs, legal fees, audit fees, Registration Statement printing and mailing costs, as well as similar expenses incurred in connection with the consummation of the Reorganization and transaction costs (if any) associated with repositioning the Selling Fund prior to the Reorganization. Fees and expenses associated with printing and mailing the Registration Statement and legal fees will be allocated equally among the Selling Funds. Audit fees directly attributable to a specific Selling Fund will be allocated to that Fund. Notwithstanding any of the foregoing, expenses will in any event be paid by the party directly incurring such expenses if and to the extent that the payment by another person of such expenses would result in the disqualification of such party as a “regulated investment company” within the meaning of Section 851 of the Code or would prevent the Reorganization from qualifying as a “reorganization” under Section 368(a)(1) of the Code. If for any reason any transaction contemplated by this Agreement is not consummated, no party shall be liable to any other party for any damages resulting therefrom, including without limitation consequential damages, except that MML Investment Advisers LLC will bear all expenses incurred by the Funds in connection with or arising out of the transactions contemplated by this Agreement, other than any brokerage or other costs relating to transactions in portfolio securities of the Funds.

9.2 Each of the Selling Trust, the Acquiring Trust, the Selling Fund, and the Acquiring Fund represents that there is no person who has dealt with it who by reason of such dealings is entitled to any broker’s or finder’s or other similar fee or commission arising out of the transactions contemplated by this Agreement.

ARTICLE X

ENTIRE AGREEMENT

10.1 The Acquiring Fund and the Selling Fund agree that neither party has made any representation, warranty or covenant not set forth herein and that this Agreement constitutes the entire agreement between the parties.

ARTICLE XI

TERMINATION

11.1 This Agreement may be terminated by any party to this Agreement by providing notice to the other parties. If the transactions contemplated by this Agreement have not been substantially completed by September 2024, this Agreement shall automatically terminate on the last day of that month unless a later date is agreed to by both the Selling Fund and the Acquiring Fund.

11.2 Except to the extent provided in Section 9.2 above, in the event of termination of this Agreement, in the absence of willful default, there shall be no liability for damages on the part of any of the Acquiring Fund, the Selling Fund, the Acquiring Trust, the Selling Trust, or their respective trustees, directors, officers and affiliates, to any other party.
