AGREEMENT

NOW, THEREFORE, in consideration of their mutual promises, each Company and MML Trust agree as follows:

ARTICLE A. Form of Agreement

Although the parties have executed this Agreement in the form of a Master Participation Agreement for administrative convenience, this Agreement shall create a separate participation agreement for Fund, as though the Company, the MML Trust and MassMutual had executed a separate, identical form of participation agreement with each Fund. No rights, responsibilities or liabilities of any Fund shall be attributed to any other Fund.

ARTICLE I. Sale of VIP MML Trust Shares

1.1. The MML Trust agrees to sell to each Account those shares of MML Trust which the Company orders on behalf of each Account, executing such orders on a daily basis at the net asset value next computed after receipt by MML Trust or its designee of the order for the shares of MML Trust. For purposes of this Section 1.1, the Company shall be the designee of MML Trust for receipt of such orders attributable to the Contracts from and receipt by such designee shall constitute receipt by MML Trust provided that MML Trust receives notice of such order by 10:00 a.m. Eastern time on the next following Business Day. “Business Day” shall mean any day on which the New York Stock Exchange is open for trading and on which MML Trust calculates its net asset value pursuant to the rules of the Securities and Exchange Commission.

1.2. MML Trust agrees to make its shares available indefinitely for purchase at the applicable net asset value per share on those days on which MML Trust calculates its net asset value pursuant to rules of the SEC and MML Trust shall use reasonable efforts to calculate such net asset value on each day which the New York Stock Exchange is open for trading. Notwithstanding the foregoing, the Board of Trustees of MML Trust (the “Board”) may refuse to sell shares of any Fund to any person, or suspend or terminate the offering of shares of any Fund if such action is required by law or by regulatory authorities having jurisdiction or is, in the sole discretion of the Board acting in good faith and in light of their fiduciary duties under federal and any applicable state laws, necessary in the best interests of the shareholders of such Fund.

1.3. MML Trust and MassMutual agree that shares of MML Trust will be sold directly or indirectly only to the Companies and their separate accounts. No shares of any Fund will be sold to the general public.

1.4. MML Trust will not sell Fund shares directly or indirectly to any insurance company or separate account unless an agreement containing provisions substantially the same as Articles I, III, V, and VII of Article II of this Agreement is in effect to govern such sales.

1.5. MML Trust agrees to redeem for cash, on the Company’s request, any full or fractional shares of a Fund, executing such requests on a daily basis at the net asset value next computed after receipt by MML Trust or its designee of the request for redemption. For purposes of this Section 1.5, the Company shall be the designee of MML Trust for receipt of requests for redemption attributable to the Contracts and receipt by such designee shall constitute receipt by MML Trust; provided that MML Trust receives notice of such request for redemption in accordance with the procedures in Section 1.1. Redemptions may be made in kind only with the written consent of all parties hereto.

1.6. The Company and MML Trust agree that purchases and redemptions of Fund shares offered by the then current prospectus of MML Trust shall be made in accordance with the provisions of such prospectus. Without limiting the foregoing, the Company represents and warrants that all purchase and redemption orders it places under Sections 1.1 and 1.5 shall result

solely from Contract Owner transactions fully received and recorded by the Company before the time as of which each applicable Fund net asset value was calculated

1.7. The Company shall pay for MML Trust shares on the next Business Day after an order to purchase MML Trust shares is made in accordance with the provisions of Section 1.1 hereof. Payment shall be in federal funds transmitted by wire. For purpose of Sections 2.7, upon receipt by MML Trust of the federal funds wired, such funds shall cease to be the responsibility of the Company and shall become the responsibility of MML Trust.

1.8. Issuance and transfer of Fund shares will be by book entry only. Stock certificates will not be issued to the Company. Shares ordered from MML Trust will be recorded in an appropriate title for each Account.

1.9. MML Trust shall furnish same day notice (by wire or telephone, followed by written confirmation) to the Company, as agent for each Account, of any income, dividends or capital gain distributions payable on Fund shares. The Company hereby elects to receive all such income dividends and capital gain distributions as are payable on the Fund shares in additional shares of that Fund. The Company reserves the right to revoke this election and to receive all such income dividends and capital gain distributions in cash. MML Trust shall notify the Company, as agent for each Account, of the number of shares so issued as payment of such dividends and distributions.

1.10. MML Trust shall make the net asset value per share for each Fund available to the Company, as agent for each Account, on a daily basis as soon as reasonably practical after the net asset value per share is calculated (normally by 6:30 p.m. Eastern time) and shall use its best efforts to make such net asset value per share available by 7:00 p.m. Eastern time.

MML Trust shall see to it that all its shares are registered and authorized for issuance in accordance with applicable federal law and, if and to the extent deemed advisable by MML Trust, in accordance with applicable state laws prior to their sale.

Without limiting the scope of the foregoing, MML Trust will at all times comply with Section 817(h) of the Code and Treasury Regulation 1.817-5, relating to the investment diversification requirements for variable annuity, endowment, or life insurance contracts and any amendments or other modifications to such Section or Regulations. In the event of a breach of this Section 6.1 by MML Trust, it will take all reasonable steps to: (a) notify Company of such breach; and (b) adequately diversify affected Fund(s) so as to achieve compliance within the grace period afforded by Regulation 1.817-5. MML Trust will provide to the Companies the results of its diversification testing on a periodic basis.

6.2 Each Company will at all times ensure that the Contracts and Accounts remain eligible to “look-through” the Accounts to the Fund portfolios for purposes of investment diversification under Section 817(h) of the Code and Regulation 1.817-5 thereunder. In the event of a breach of this Section 6.2, the Company will take all reasonable steps to: (a) notify MML Trust of such breach; and (b) remedy the breach so as to achieve compliance within the grace period afforded by Regulation 1.817-5.

ARTICLE VII. Potential Conflicts

7.1. The MML Trust Board will monitor MML Trust for the existence of any material irreconcilable conflict between the interests of the contract owners of all separate accounts investing directly or indirectly in MML Trust. An irreconcilable material conflict may

arise for a variety of reasons, including: (a) an action by any state insurance regulatory authority; (b) a change in applicable federal or state insurance, tax, or securities laws or regulations, or a public ruling, private letter ruling, no-action or interpretative letter, or any similar action by insurance, tax, or securities regulatory authorities; (c) an administrative or judicial decision in any relevant proceeding; (d) the manner in which the investments of any Fund are being managed; (e) a difference in voting instructions given by variable annuity contract and variable life insurance contract owners; or (f) a decision by an insurer to disregard the voting instructions of contract owners. The MML Trust Board shall promptly inform each Company if it determines that an irreconcilable material conflict exists and the implications thereof.

7.2. Each Company will report any potential or existing conflicts of which it is aware to the MML Trust Board. The Company will assist the MML Trust Board in carrying out its responsibilities under applicable provisions of the 1940 Act, including, among others, Rule 6e-3(t)(b)(15), by providing the MML Trust Board with all information reasonably necessary for the MML Trust Board to consider any issues raised. This includes, but is not limited to, an obligation by the Company to inform the MML Trust Board whenever contract owner voting instructions are disregarded.

7.3. If it is determined by a majority of the MML Trust Board, or a majority of its disinterested trustees, that a material irreconcilable conflict exists, each Company shall, at their expense and to the extent reasonably practicable (as determined by a majority of the disinterested trustees), take whatever steps are necessary to remedy or eliminate the irreconcilable material conflict, up to and including: (1) withdrawing the assets allocable to some or all of the separate accounts from MML Trust or any Fund and reinvesting such assets in a different investment medium, including (but not limited to) another Fund of MML Trust, or submitting the question whether such segregation should be implemented to a vote of all affected Contract owners and, as appropriate, segregating the assets of any appropriate group (i.e., annuity contract owners, life insurance contract owners, or variable contract owners of one or more of the Companies) that votes in favor of such segregation, or offering to the affected Contract owners the option of making such a change; and (2) establishing a new registered management investment company or managed separate account.

7.4. If a material irreconcilable conflict arises because of a decision by a Company to disregard contract owner voting instructions and that decision represents a minority position or would preclude a majority vote, the Company may be required, at MML Trust’s election, to withdraw the affected Account’s investment in MML Trust and terminate this Agreement with respect to such Account; provided, however that such withdrawal and termination shall be limited to the extent required by the foregoing material irreconcilable conflict as determined by a majority of the disinterested members of the MML Trust Board. Any such withdrawal and termination must take place within six (6) months after MML Trust gives written notice that this provision is being implemented, and until the end of that six-month period MML Trust shall continue to accept and implement orders by the Company for the purchase (and redemption) of shares of MML Trust.

7.5. If a material irreconcilable conflict arises because a particular state insurance regulator’s decision applicable to a Company conflicts with the majority of other state regulators, then the Company will withdraw the affected Account’s investment in MML Trust and terminate this Agreement with respect to such Account within six (6) months after the MML Trust Board informs the Company in writing that it has determined that such decision has created an irreconcilable material conflict; provided, however, that such withdrawal and termination shall be limited to the extent required by the foregoing material irreconcilable conflict as determined by a majority of the disinterested members of the MML Trust Board. Until the end of the foregoing six-month period, MML Trust shall continue to accept and implement orders by the Company, on behalf of MML Trust, for the purchase (and redemption) of shares of MML Trust.

7.6. For purposes of Sections 7.3 through 7.6 of this Agreement, a majority of the disinterested members of the MML Trust Board shall determine whether any proposed action adequately remedies any irreconcilable material conflict, but in no event will MML Trust be required to establish a new funding medium for the Contracts. The Company shall not be required by Section 7.3 to establish a new funding medium for the Contracts if an offer to do so has been declined by vote of a majority of Contract owners materially adversely affected by the irreconcilable material conflict. In the event that the MML Trust Board determines that any proposed action does not adequately remedy any irreconcilable material conflict, then the Company will withdraw the Account’s investment in MML Trust and terminate this Agreement within six (6) months after the MML Trust Board informs the Company in writing of the foregoing determination, provided, however, that such withdrawal and termination shall be limited to the extent required by any such material irreconcilable conflict as determined by a majority of the disinterested members of the MML Trust Board.

7.7. If and to the extent that Rule 6e-2 and Rule 6e-3(T) are amended, or Rule 6e-3 is adopted, to provide exemptive relief from any provision of the 1940 Act or the rules promulgated thereunder with respect to mixed or shared funding on terms and conditions materially different from those contained in those rules currently then: (a) MML Trust and/or the Companies, as appropriate, shall take such steps as may be necessary to comply with Rules 6e-2 and 6e-3(T), as amended, and Rule 6e-3, as adopted, to the extent such rules are applicable; and (b) Sections 3.5, 3.6, 7.1, 7.2, 7.3, 7.4, and 7.5 of this Agreement shall continue in effect only to the extent that terms and conditions substantially identical to such Sections are contained in such Rule(s) as so amended or adopted.

Each Company agrees to indemnify and hold harmless MML Trust, each member of the MML Trust Board, and MML Trust officers and each person, if any, who controls MML Trust within the meaning of Section 15 of the 1933 Act (collectively, the “Indemnified Parties” for purposes of this Section 8.1) against any and all losses, claims, damages, liabilities (including amounts paid in settlement with the written consent of the Company) or litigation (including legal and other expenses), to which the Indemnified Parties may become subject under

any statute, regulation, at common law or otherwise, insofar as such losses, claims, damages, liabilities or expenses (or actions in respect thereof) or settlements are related to the sale or acquisition of, or investment in, MML Trust’s shares or the Contracts and:

(i)

arise out of or are based upon any untrue statements or alleged untrue statements of any material fact contained in the Disclosure Documents for the Contracts, or contained in the Contracts or sales literature or other promotional material for the Contracts (or any amendment or supplement to any of the foregoing), or arise out of or are based upon the omission or the alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, provided that this agreement to indemnify shall not apply as to any Indemnified Party if such statement or omission or such alleged statement or omission was made in reliance upon and in conformity with information furnished to the Company by or on behalf of MML Trust for use in any Disclosure Document relating to the Contracts or in the Contracts or sales literature or other promotional material (or any amendment or supplement) or otherwise for use in connection with the sale of the Contracts or MML Trust shares; or

(ii)

arise out of or as a result of statements or representations (other than statements or representations contained in the registration statement, prospectus or sales literature of MML Trust not supplied by the Company, or persons under its control) or wrongful conduct of the Company or persons under its control, with respect to the sale or distribution of the Contracts or MML Trust shares; or

(iii)

arise out of any untrue statement or alleged untrue statement of a material fact contained in a Disclosure Document or sales literature of MML Trust or any amendment thereof or supplement thereto or the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading if such a statement or omission was made in reliance upon and in conformity with information furnished to MML Trust by or on behalf of the Company; or

(iv)

arise as a result of any failure by the Company to provide the services and furnish the materials under the terms of this Agreement; or

(v)

arise out of or result from any material breach of any representation and/or warranty made by the Company in this Agreement or arise out of or result from any other material breach of this Agreement by the Company, as limited by and in accordance with the provisions of Sections 8.1(b) and 8.1(c) hereof.

8.1(b). Each Company shall not be liable under this indemnification provision with respect to any losses, claims, damages, liabilities or litigation incurred or assessed against an Indemnified Party as such may arise from such Indemnified Party’s willful misfeasance, bad faith, or gross negligence in the performance of such Indemnified Party’s duties or by reason of such Indemnified Party’s reckless disregard of obligations or duties under this Agreement or to any party to this Agreement, whichever is applicable.

8.1(c). Each Company shall not be liable under this indemnification provision with respect to any claim made against an Indemnified Party unless such Indemnified Party shall have notified the Company in writing within a reasonable time after the summons or other first legal process giving information of the nature of the claim shall have been served upon such Indemnified Party (or after such Indemnified Party shall have received notice of such service on any designated agent), but failure to notify the Company of any such claim shall not relieve the Company from any liability which it may have to the Indemnified Party against whom such action is brought otherwise than on account of this indemnification provision. In case any such action is brought against the Indemnified Parties, the Company shall be entitled to participate, at its own expense, in the defense of such action.

After notice from the Company to such party of the Company’s election to assume the defense thereof, the Indemnified Party shall bear the fees and expenses of any additional counsel retained by it, and the Company will not be liable to such party under this Agreement for any legal or other expenses subsequently incurred by such party independently in connection with the defense thereof other than reasonable costs of investigation.

8.1(d). The Indemnified Parties will promptly notify each Company of the commencement of any litigation or proceedings against them in connection with the issuance or sale of MML Trust shares, or the Contracts or the operation of MML Trust or the Accounts.

(i)

arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in the Disclosure Documents or prospectus or sales literature or other promotional material of MML Trust (or any amendment or supplement to any of the foregoing), or arise out of or are based upon the omission or the alleged omission to state therein a

material fact required to be stated therein or necessary to make the statements therein not misleading, provided that this agreement to indemnify shall not apply as to any Indemnified Party if such statement or omission or such alleged statement or omission was made in reliance upon and in conformity with information furnished to MassMutual or MML Trust by or on behalf of the Company for use in the registration statement or prospectus for MML Trust or in sales literature (or any amendment or supplement) or otherwise for use in connection with the sale of the Contracts or MML Trust shares; or

(ii)

arise out of or as a result of statements or representations (other than statements or representations contained in the Disclosure Documents or sales literature or other promotional material for the Contracts not supplied by MassMutual or persons under its control) or wrongful conduct of MML Trust or MassMutual or persons under their control, with respect to the sale or distribution of the Contracts or MML Trust shares; or

(iii)

arise out of any untrue statement or alleged untrue statement of a material fact contained in a Disclosure Document or sales literature or other promotional material covering the Contracts, or any amendment thereof or supplement thereto, or the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statement or statements therein not misleading, if such statement or omission was made in reliance upon and in conformity with information furnished to the Company by or on behalf of MML Trust; or

(iv)

arise as a result of any failure by MML Trust to provide the services and furnish the materials under the terms of this Agreement (including a failure, whether unintentional or in good faith or otherwise, to comply with the diversification requirements specified in Article VI of this Agreement); or

(v)

arise out of or result from any material breach of any representation and/or warranty made by MML Trust in this Agreement or arise out of or result from any other material breach of this Agreement by MML Trust; as limited by and in accordance with the provisions of Sections 8.2(b) and 8.2(c) hereof.

8.2(b). MML Trust shall not be liable under this indemnification provision with respect to any losses, claims, damages, liabilities or litigation to which an Indemnified Party would otherwise be subject by reason of such Indemnified Party’s willful misfeasance, bad faith, or gross negligence in the performance of such Indemnified Party’s duties or by reason of such Indemnified Party’s reckless disregard of obligations and duties under this Agreement or to any party under this Agreement, whichever is applicable.

8.2(c). MML Trust shall not be liable under this indemnification provision with respect to any claim made against an Indemnified Party unless such Indemnified Party shall have notified MML Trust in writing within a reasonable time after the summons or other first legal process giving information of the nature of the claim shall have been served upon such Indemnified Party (or after such Indemnified Party shall have received notice of such service on any designated agent), but failure to notify MML Trust of any such claim shall not relieve MML Trust from any liability which it may have to the Indemnified Party against whom such action is brought otherwise than on account of this indemnification provision. In case any such action is brought against the Indemnified Parties, MML Trust will be entitled to participate, at its own expense, in the defense thereof. MML Trust also shall be entitled to assume the defense thereof, with counsel satisfactory to the party named in the action. After notice from MML Trust to such party of MML Trust’s election to assume the defense thereof, the Indemnified Party shall bear the fees and expenses of any additional counsel retained by it, and MML Trust will not be liable to such party under this Agreement for any legal or other expenses subsequently incurred by such party independently in connection with the defense thereof other than reasonable costs of investigation.

8.2(d). Each Company agrees promptly to notify MML Trust of the commencement of any litigation or proceedings against it or any of its officers or directors in connection with the issuance or sale of MML Trust shares or the Contracts or the operation of MML Trust or the Accounts.

ARTICLE X. Termination

10.1. This Agreement shall continue in full force and effect until the first to occur of:

(a)

termination by any party for any reason by four (4) months’ advance written notice delivered to the other parties; or

(c)

termination by a Company by written notice to MML Trust and MassMutual with respect to any Fund in the event any of such Fund’s shares are not registered, issued or sold in accordance with applicable state and/or federal law or such law precludes the use of such shares as an underlying investment medium of the Contracts issued or to be issued by the Company; or

(d)

termination by a Company by written notice to MML Trust and MassMutual with respect to any Fund in the event that such Fund ceases to qualify as a Regulated Investment Company under Subchapter M of the Code or under any successor or similar provision, or if the Company reasonably believes that the Fund may fail to so qualify; or

(e)

termination by a Company by written notice to MML Trust and MassMutual with respect to any Fund in the event that such Fund fails to meet the diversification requirements specified in Article VI hereof; or

(f)

termination by either MML Trust or MassMutual by written notice to a Company if either one or both of MML Trust or MassMutual, respectively, shall determine, in their sole judgment exercised in good faith, the Company and/or its affiliated companies has suffered a material adverse change in its business, operations, financial condition or prospects since the date of this Agreement or is the subject of material adverse publicity; or

10.2. Notwithstanding any termination of this Agreement, MML Trust and MassMutual shall at the option of each Company, continue to make available additional shares of MML Trust pursuant to the terms and conditions of this Agreement, to the extent necessary to fund all Contracts in effect on the effective date of termination of this Agreement (hereinafter referred to as “Existing Contracts”). Specifically, without limitation, the owners of the Existing Contracts shall be permitted to reallocate investments in MML Trust, redeem investments in MML Trust and/or invest in MML Trust upon the making of additional purchase payments under the Existing Contracts. The parties agree that this Section 10.2 shall not apply to: (a) any terminations under Article VII and the effect of such Article VII terminations shall be governed by Article VII of this Agreement; or (b) any termination occurring under the conditions described in Subsections 10.1(h) or (i) above.

10.3. The provisions of Articles II (Representations and Warranties), VIII (Indemnification), IX (Applicable Law) and XII (Miscellaneous) shall survive termination of this Agreement.

with Section 10.2, except that MML Trust and MassMutual shall have no further obligation to make MML Trust shares available to fund Contracts issued after termination.

10.4. Each Company shall not redeem MML Trust shares attributable to the Contracts (as opposed to MML Trust shares attributable to the Company’s assets held in the Account) except as: (i) necessary to implement Contract Owner initiated or approved transactions; (ii) required by state and/or federal laws or regulations or judicial or other legal precedent of general application (hereinafter referred to as a “Legally Required Redemption”); or (iii) necessary to effect a separate account transaction that is permitted by an order of the SEC pursuant to Section 26(c) of the 1940 Act. Upon request, the Company will promptly furnish to MML Trust and MassMutual the opinion of counsel for the Company (which counsel shall be reasonably satisfactory to MML Trust and MassMutual) to the effect that any redemption pursuant to clause (ii) above is a Legally Required Redemption. Furthermore, except in cases where permitted under the terms of the Contracts, the Company shall not prevent Contract owners from allocating payments to a Fund that was otherwise available under the Contracts without first giving MML Trust or MassMutual ninety (90) days notice of its intention to do so.
