THIS AGREEMENT is made this 14 day of March, 2002, between JANUS ASPEN SERIES, an open-end management investment company organized as a Delaware business trust (the “Trust”), and Massachusetts Mutual Life Insurance Company, a life insurance company organized under the laws of the Commonwealth of Massachusetts (the “Company”), on its own behalf and on behalf of each segregated asset account of the Company set forth on Schedule A, as may be amended from time to time (the “Accounts”).

WHEREAS, the Trust has registered with the Securities and Exchange Commission as an open-end management investment company under the Investment Company Act of 1940, as amended (the “1940 Act”), and the beneficial interest in the Trust is divided into several series of shares, each series representing an interest in a particular managed portfolio of securities and other assets (the “Portfolios”); and

WHEREAS, the Trust has registered the offer and sale of a class of shares designated the Service Shares (“Shares”) of each of its Portfolios under the Securities Act of 1933, as amended (the “1933 Act”); and

WHEREAS, the Trust desires to act as an investment vehicle for separate accounts established for variable life insurance policies and variable annuity contracts to be offered by insurance companies that have entered into participation agreements with the Trust (the “Participating Insurance Companies”); and

WHEREAS, the Trust has received an order from the Securities and Exchange Commission granting Participating Insurance Companies and their separate accounts exemptions from the provisions of Section 9(a), 13(a), 15(a) and 15(b) of the 1940 Act, and Rules 6e-2(b)(15) and 6e-3(T)(b)(15) thereunder, to the extent necessary to permit shares of the Trust to be sold to and held by variable annuity and variable life insurance separate accounts of both affiliated and unaffiliated life insurance companies and certain qualified pension and retirement plans (the “Exemptive Order”); and

WHEREAS, the Company has registered or will register (unless registration is not required under applicable law) certain variable life insurance policies and/or variable annuity contracts under the 1933 Act (the “Contracts”); and

WHEREAS, the Company has registered or will register each Account as a unit investment trust under the 1940 Act; and

WHEREAS, the Company desires to utilize shares of one or more Portfolios as an investment vehicle of the Accounts;

NOW, THEREFORE, in consideration of their mutual promises, the parties agree as follows:

1.1 The Trust shall make shares of its Portfolios listed on Schedule B available to the Accounts at the net asset value next computed after receipt of such purchase order by the Trust (or its agent), as established in accordance with the provisions of the then current prospectus of the Trust. Shares of a particular Portfolio of the Trust shall be ordered in such quantities and at such times as determined by the Company to be necessary to meet the requirements of the Contracts. The Trustees of the Trust (the “Trustees”) may refuse to sell Shares of any Portfolio to any person, or suspend or terminate the offering of Shares of any Portfolio if such action is required by law or by regulatory authorities having jurisdiction or is, in the sole discretion of the Trustees 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 Portfolio.

1.2 The Trust will redeem any full or fractional shares of any Portfolio when requested by the Company on behalf of an Account at the net asset value next computed after receipt by the Trust (or its agent) of the request for redemption, as established in accordance with the provisions of the then current prospectus of the Trust. The Trust shall make payment for such Shares in the manner established from time to time by the Trust, but in no event shall payment be delayed for a greater period than is permitted by the 1940 Act.

1.3 For the purposes of Sections 1.1 and 1.2, the Trust hereby appoints the Company as its agent for the limited purpose of receiving and accepting purchase and redemption orders resulting from investment in the payments under the Contracts. Receipt by the Company shall constitute receipt by the Trust provided that i) such orders are received by the Company in good order prior to the time the net asset value of each Portfolio is priced in accordance with its prospectus and ii) the Trust receives notice of such orders by 10:00 a.m. New York 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 the Trust calculates its net asset value pursuant to the rules of the Securities and Exchange Commission.

1.4 Purchase orders that are transmitted to the Trust in accordance with Section 1.3 shall be paid for no later than 3:00 p.m. New York time on the same Business Day that the Trust receives notice of the order. Payments shall be made in federal funds transmitted by wire.

1.5 Issuance and transfer of the Trust’s Shares will be by book entry only. Stock certificates will not be issued to the Company or the Account. Shares ordered from the Trust will be recorded in the appropriate title for each Account or the appropriate subaccount of each Account.

1.6 The Trust shall furnish prompt notice to the Company of any income dividends or capital gain distributions payable on the Trust’s Shares. The Company hereby elects to receive all such income dividends and capital gain distributions as are payable on a Portfolio’s Shares in additional Shares of that Portfolio. The Trust shall notify the Company of the number of Shares so issued as payment of such dividends and distributions.

1.7 The Trust shall make the net asset value per Share for each Portfolio available to the Company on a daily basis as soon as reasonably practical after the net asset value per Share is calculated and shall use its best efforts to make such net asset value per Share available by 6 p.m. New York time. If the Trust provides the Company with materially incorrect share net asset value information, the Trust shall make an adjustment to the number of shares purchased or redeemed for the Accounts to reflect the correct share net asset value per share. Any material error in the calculation or reporting of net asset value per share, dividend or capital gains information shall be reported promptly upon discovery to the Company.

1.8 The Trust agrees that its Shares will be sold only to Participating Insurance Companies and their separate accounts and to certain qualified pension and retirement plans to the extent permitted by the Exemptive Order. No Shares of any Portfolio will be sold directly to the general public. The Company agrees that Trust Shares will be used only for the purposes of funding the Contracts and Accounts listed in Schedule A, as amended from time to time.

1.9 The Trust agrees that all Participating Insurance Companies shall have the obligations and responsibilities regarding pass-through voting and conflicts of interest corresponding to those contained in Section 2.8 and Article IV of this Agreement.

1.10 All orders accepted by the Company shall be subject to the terms of the then current prospectus of each Portfolio, including without limitation, policies regarding minimum account sizes, market timing and excessive trading. The Company shall use its best efforts, and shall reasonably cooperate with, the Trust to enforce stated prospectus policies regarding transactions in Shares, particularly those related to market timing. The Company acknowledges that orders accepted by it in violation of the Trust’s stated policies may be subsequently revoked or cancelled by the Trust and that the Trust shall not be responsible for any losses incurred by the Company or Contract or Account as a result of such cancellation. The Trust or its agent shall notify the Company of such cancellation prior to 12:00 p.m. EST on the next day following Business Day after any such cancellation.

In addition, the Company acknowledges that the Trust has the right to refuse any purchase order for any reason, particularly if the Trust determines that a Portfolio would be unable to invest the money effectively in accordance with its investment policies or would otherwise be adversely affected due to the size of the transaction, frequency of trading by the account or other factors. The Trust agrees to cooperate with the Company in establishing and communicating to the Company parameters for trades that the Trust will consider to be market timing activity prior to rejecting any trades. The Trust agrees to provide the Company with a written warning of its intention to begin rejecting trades before it begins rejecting trades due to market timing.

1.11 The Trust shall provide the Company account look-up access through DST Vision or a similar electronic look-up feature to review daily account balances.

2.1 The Trust shall prepare and be responsible for filing with the Securities and Exchange Commission and any sate regulators requiring such filing all shareholder reports, notices, proxy materials (or similar materials such as voting instructions solicitation materials), prospectuses and statements of additional information of the Trust. The Trust shall bear the costs of registration and qualification of its shares, preparation and filing of the documents listed in this Section 2.1 and all taxes to which an issuer is subject on the issuance and transfer of its shares.

The Trust shall provide the Company with a copy the Shares’ statement of additional information in a form suitable for duplication by the Company. The Trust (at its expense) shall provide the Company with copies of any Trust-sponsored proxy materials in such quantity as the Company shall reasonably require for distribution to Contract owners. The Trust will provide these documents within a reasonable period of time so that the Company can distribute them to contract owners in a timely manner.

2.3 (a) The Company shall bear the costs of printing and distributing the Trust’s Shares’ prospectus, statement of additional information, shareholder reports and other shareholder communications to owners of and applicants for policies for which Shares of the Trust are serving or are to serve as an investment vehicle. The Company shall bear the costs of distributing proxy materials (or similar materials such as voting solicitation instructions) to Contract owners. The Company assumes sole responsibility for ensuring that such materials

(b) If the Company elects to include any materials provided by the Trust, specifically prospectuses, SAIs, shareholder reports and proxy materials, on its web site or in any other computer or electronic format, the Company assumes sole responsibility for maintaining such materials in the form provided by the Trust and for promptly replacing such materials with all updates provided by the Trust

Except as provided in Section 2.5, the Company shall not use any Janus Mark on its own behalf or on behalf of the Accounts or Contracts in any registration statement, advertisement, sales literature or other materials relating to the Accounts or Contracts without the prior written consent of Janus Capital. All references contained in this Agreement to “the name or mark ‘Janus’” shall include but not be limited to the Janus logo, the website www.janus.com and any and all electronic links relating to such website. The Company will make no use of the name or mark “Janus” except as expressly provided in this agreement or expressly authorized by Janus Capital in writing. All goodwill associated with the name and mark “Janus” shall inure to the benefit of Janus Capital. Upon termination of this Agreement for any reason, the Company shall cease any and all use of any Janus Mark(s).

The Company shall furnish, or shall cause to be furnished, to the Trust or its designee, each piece of sales literature or other promotional material in which the Trust or its investment adviser is named, at least ten Business Days prior to its use. No such material shall be used if the Trust or its designee reasonably objects to such use within ten Business Days after receipt of such material. No review of sales literature or other promotional material produced by the Company shall be necessary if all references contained in such materials regarding Trust are identical to those references that appear in Trust’s current prospectus (or prospectuses) or statement of additional information.

2.6 The Company shall not give any information or make any representations or statements on behalf of the Trust or concerning the Trust or its investment adviser in connection with the sale of the Contracts other than information or representations contained in and accurately derived from the registration statement or prospectus for the Trust Shares (as such registration statement and prospectus may be amended or supplemented from time to time), reports of the Trust, Trust-sponsored proxy statements, or in sales literature or other promotional material approved by the Trust or its designee, except as required by legal process or regulatory authorities or with the written permission of the Trust or its designee.

2.7 The Trust shall not give any information or make ay representations or statements on behalf of the Company or concerning the Company, the Accounts or the Contracts other than information or representations contained in and accurately derived from the registration statement or prospectus for the Contracts (as such registration statement and prospectus may be amended or supplemented from time to time), or in materials approved by the Company for distribution including sales literature or other promotional materials, except as required by legal process or regulatory authorities or with the written permission of the Company.

2.8 So long as, and to the extent that the Securities and Exchange Commission interprets the 1940 Act to require pass-through voting privileges for variable policyowners, the Company will provide pass-through voting privileges to owners of policies whose cash values are invested, through the Accounts, in shares of the Trust. The Trust shall require all Participating Insurance Companies to calculate voting privileges in the same manner and the Company shall be responsible for assuring that the Accounts calculate voting privileges in the manner established by the Trust. With respect to each Account, the Company will vote shares of the Trust held by the Account and for which no timely voting instructions from policyowners are received as well as Shares it owns that are held by that Account, in the same proportion as those Shares for which voting instructions are received. The Company and its agents will in no way recommend or oppose or interfere with the solicitation of proxies for Trust shares held by Contract owners without the prior written consent of the Trust, which consent may be withheld in the Trust’s sole discretion. The Trust will use its best efforts to provide the Company with reasonable advance notice of proxy solicitations and prospectus supplements.

2.9 The Company shall notify the Trust of any applicable state insurance laws that restrict the Portfolios’ investments or otherwise affect the operation of the Trust and shall notify the Trust of any changes in such laws.

3.1 The Company represents and warrants that it is an insurance company duly organized and in good standing under the laws of the Commonwealth of Massachusetts and that it has legally and validly established each Account as a segregated asset account under such law on the date set forth in Schedule A.

3.2 The Company represents and warrants that each Account has been registered or, prior to any issuance or sale of the Contracts, will be registered as a unit investment trust in accordance with the provisions of the 1940 Act.

3.3 The Company represents and warrants that the Contracts or interests in the Accounts (1) are or, prior to issuance, will be registered as securities under the 1933 Act or, alternatively (2) are not registered because they are properly exempt from registration under the 1933 Act or will be offered exclusively in transactions that are properly exempt from registration under the 1933 Act. The Company further represents and warrants that the Contracts will be issued and sold in compliance in all material respects with all applicable federal and state laws; and the sale of the Contracts shall comply in all material respects with state insurance suitability requirements.

3.4 The Trust represents and warrants that is duly organized and validly existing under the laws of the State of Delaware.

3.5 The Trust represents and warrants that the Trust shares offered and sold pursuant to this Agreement will be registered under the 1933 Act and the Trust shall be registered under the 1940 Act prior to any issuance or sale of such Shares. The Trust shall amend its registration statement under the 1933 Act and the 1940 Act from time to time as required in order to effect the continuous offering of its Shares. The Trust shall register and qualify its Shares for sale in accordance with the laws of the various states only if and to the extent deemed advisable by the Trust.

3.6 The Trust represents and warrants that the investments of each Portfolio will comply with the diversification requirements set forth in Section 817(h) of the Internal Revenue Code of 1986, as amended, and the rules and regulations thereunder. The Trust will notify the Company immediately upon having a reasonable basis for believing any Portfolio has ceased to comply and will immediately take all reasonable steps to adequately diversify the Portfolio to achieve compliance. Further, the Trust will notify the Company immediately upon having a reasonable basis for believing that a variable contract of any other company or companies which use the Trust as an investment option fail to comply with the diversification requirements mentioned above.

4.1 The parties acknowledge that the Trust’s shares may be made available for investment to other Participating Insurance Companies. In such event, the Trustees will monitor the Trust for the existence of any material irreconcilable conflict between the interests of the contract owners of all Participating Insurance Companies. 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 Portfolio 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 Trustee shall promptly inform the Company if they determine that an irreconcilable material conflict exists and the implication thereof.

4.2 The Company agrees to promptly report any potential or existing conflicts of which it is aware to the Trustees. The Company will assist the Trustees in carrying out their responsibilities under the Exemptive Order by providing the Trustees with all information reasonably necessary for the Trustees to consider any issues raised including, but not limited to, information as to a decision by the Company to disregard Contract owner voting instructions.

4.3 If it is determined by a majority of the Trustees, or a majority of its disinterested Trustees, that a material irreconcilable conflict exists that affects the interests of Contract owners, the Company shall, in cooperation with other Participating Insurance Companies whose contract owners are also affected, at its expense and to the extent reasonably practicable (as determined by the Trustees) take whatever steps are necessary to remedy or eliminate the irreconcilable material conflict, which steps could include: (a) withdrawing the assets allocable to some or all of the Accounts from the Trust or any Portfolio and reinvesting such assets in a different investment medium, including (but not limited to) another Portfolio of the Trust, or submitting the question of whether or not 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 Participating Insurance Companies) that votes in favor of such segregation, or offering to the affected Contract owners the option of making such a change; and (b) establishing a new registered management investment company or managed separate account.

4.4 If a material irreconcilable conflict arises because of a decision by the 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 the Trust’s election, to

withdraw the affected Account’s investment in the 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 Trustees. Any such withdrawal and termination must take place within six (6) months after the Trust gives written notice that this provision is being implemented. Until the end of such six (6) month period, the Trust shall continue to accept and implement orders by the Company for the purchase and redemption of shares of the Trust.

4.5 If a material irreconcilable conflict arises because a particular state insurance regulator’s decision applicable to the Company conflicts with the majority of other state regulators, then the Company will withdraw the affected Account’s investment in the Trust and terminate this Agreement with respect to such Account within six (6) months after the Trustees inform 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 Trustees. Until the end of such six (6) month period, the Trust shall continue to accept and implement orders by the Company for the purchase and redemption of Shares of the Trust.

4.6 For purposes of Sections 4.3 through 4.6 of this Agreement, a majority of the disinterested Trustees shall determine whether any proposed action adequately remedies any irreconcilable material conflict, but in no event will the Company be required 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 Trustees determine that any proposed action does not adequately remedy any irreconcilable material conflict, then the Company will withdraw the Account’s investment in the Trust and terminate this Agreement within six (6) months after the Trustees inform 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 Trustees.

4.7 The Company shall at least annually submit to the Trustees such reports, materials or data as the Trustees may reasonably request so that the Trustees may fully carry out the duties imposed upon them by the Exemptive Order, and said reports, materials and data shall be submitted more frequently if deemed appropriate by the Trustees.

4.8 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 (as defined in the Exemptive Order) on terms and conditions materially different from those contained in the Exemptive Order, then the Trust and/or the Participating Insurance 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.

5.1 Indemnification By the Company. The Company agrees to indemnify and hold harmless the Trust and each of its Trustees, officers, employees and agents and each person, if any, who controls the Trust within the meaning of Section 15 of the 1933 Act (collectively, the “Indemnified Parties” for purposes of this Article V) against any and all losses, claims, damages, liabilities (including amounts paid in settlement with the written consent of the Company) or expenses (including the reasonable costs of investigating or defending any alleged loss, claim, damage, liability or expense and reasonable legal counsel fees incurred in connection therewith) (collectively, “Losses”), to which the Indemnified Parties may become subject under any statute or regulation, or at common law or otherwise, insofar as such Losses:

(a) arise out of or are based upon any untrue statements or alleged untrue statements of any material fact contained in the registration statement or prospectus for the Trust (or any amendment or supplement thereto), (collectively, “Trust Documents” for the purposes of this Article V), 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 indemnity 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 was accurately derived from written information furnished to the Trust by or on behalf of the Company for use in Trust Documents or otherwise for use in connection with the sale of the Contracts or Trust Shares; or

5.4 Neither the Company nor the Trust shall be liable under the indemnification provisions of Section 5.1 or 5.2, as applicable, with respect to any claim made against an Indemnified Party unless such Indemnified Party shall have notified the other party in writing within a reasonable time after the summons, or other first written notification, giving information of the nature of the claim shall have been served upon or otherwise received by such Indemnified Party (or after such Indemnified Party shall have received notice of service upon or other notification to any designated agent), but failure to notify the party against whom indemnification is sought of any such claim shall not relieve that party from any liability which it may have to the Indemnified Party in the absence of Sections 5.1 and 5.2.
