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

ARTICLE 1

Sale of the Fund Shares

1.1 Subject to Section 1.3, the Fund shall make Shares of the Portfolios available to the Accounts at net asset value in accordance with the operational procedures mutually agreed to by the Fund and the Company from time to time and the provisions of the then current prospectuses and statements of additional information of the Portfolios (collectively, the “Prospectus”). Shares of a particular Portfolio of the Fund 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 Directors of the Fund (the “Directors”) may refuse to sell Shares of any Portfolio to any person (including the Company and the Accounts), or suspend or terminate the offering of Shares of any Portfolio, if such action is required by law or by regulatory authorities having jurisdiction in their sole discretion when acting in good faith and in light of their fiduciary duties under federal and any applicable state laws, if they deem such actions necessary in the best interests of the shareholders of such Portfolio.

1.1(a) If there are corrections to a Portfolio’s net asset value, the following provisions shall apply:

Fund/SERV Transactions. If the parties choose to use the National Securities Clearing Corporation’s Mutual Fund Settlement, Entry and Registration Verification (“Fund/SERV”) system, any corrections to a Portfolio’s net asset value for the prior Trade Date (as hereinafter defined) will be submitted through the Mutual Fund Profile with the correct net asset value and applicable date. If the corrections are dated later than Trade Date plus one, an electronic transmission should be sent in addition to the Mutual Fund Profile submission; or

Manual Transactions. If the parties choose not to use Fund/SERV, if there are technical problems with Fund/SERV, or if the parties are not able to transmit or receive information through Fund/SERV, any corrections to a Portfolio’s net asset value should be communicated by facsimile or by electronic transmission, and will include for each day on which an adjustment has occurred, the incorrect Portfolio net asset value, the correct net asset value, and, to the extent communicated to Portfolio shareholders, the reason for the adjustment.

1.1(b) Fund/SERV Transactions. If the parties choose to use Fund/SERV or any other NSCC service, the following provisions shall apply:

The Company and the Fund or its designee will each be bound by the rules of the National Securities Clearing Corporation (“NSCC”) and the terms of any NSCC agreement filed by it with the NSCC. Without limiting the generality of the following provisions of this section, the Company and the Fund or its designee will each perform any and all duties, functions, procedures and responsibilities assigned to it and as otherwise established by the NSCC applicable to Fund/SERV, the Mutual Fund Profile Service, the Networking Matrix Level utilized and any other relevant NSCC service or system (collectively, the “NSCC Systems”).

Any information transmitted through the NSCC Systems by any party or its delegate/designee to the other and pursuant to this Agreement will be accurate, complete, and in the format prescribed by the NSCC. Each party will adopt, implement and maintain procedures reasonably designed to ensure the accuracy of all transmissions through the NSCC Systems and to limit the access to, and the inputting of data into, the NSCC Systems to persons specifically authorized by such party.

On each Business Day (as hereinafter defined), the Company shall aggregate and calculate the net purchase and redemption orders for portfolio shares for each Account received by the Company prior to the Close of Trading (as hereinafter defined) on each Business Day. The Company shall communicate to the Fund or its designee for that Business Day, by Fund/SERV, the net aggregate purchase or redemption orders (if any) for each Account received by the Close of Trading on such Business Day (the “Trade Date”) no later than 7:00 a.m. Eastern Time (or such other time as may be agreed by the parties from time to time) on the Business Day following the Trade Date. All orders received by the Company after the Close of Trading on a Business Day shall not be transmitted to NSCC prior to the following Business Day. The Fund or its designee shall treat all trades communicated to the Fund or its designee in accordance with this provision as if received prior to the Close of Trading on the Trade Date.

All orders are subject to acceptance by the Fund or its designee and become effective only upon confirmation by the Fund or its designee. Upon confirmation, the Fund or its designee will verify total purchases

and redemptions and the closing share position for each Account. In the case of delayed settlement, the Fund or its designee shall make arrangements for the settlement of redemptions by wire no later than the time permitted for settlement of redemption orders by the ▇▇▇▇ ▇▇▇.

1.1(c) Manual Transactions. If the parties choose not to use Fund/SERV, if there are technical problems with Fund/SERV, or if the parties are not able to transmit or receive information through Fund/SERV, or in the event there are rejected trades which require manual settlement due to exceptions processing, the following provisions shall apply:

Next Day Transmission of Orders. On each Business Day, the Company shall aggregate and calculate the net purchase and redemption orders for each Account received by the Company prior to the Close of Trading on such Business Day. Prior to 9:00 a.m. Eastern Time (or such other time as may be agreed by the parties from time to time) on the next following Business Day, the Company shall communicate to the Fund or its designee by e-mail or facsimile or, in the Company’s discretion, by telephone or any other method agreed upon by the parties, the net aggregate purchase or redemption orders (if any) for each Account received by the Close of Trading on the prior Business Day. All orders communicated to the Fund or its designee by the 9:00 a.m. deadline (or such other time as may be agreed by the parties from time to time) shall be treated by the Fund or its designee as if received prior to the Close of Trading on the Trade Date.

Purchases. The Company will use its best efforts to transmit each purchase order to the Fund or its designee in accordance with written instructions previously provided by the Fund or its designee to the Company. The Company will use its best efforts to initiate by wire transfer to BRIL or its designee purchase amounts no later than the close of the Federal Reserve Wire Transfer System (the “Fedwire System”) on the next Business Day following the Trade Date.

Redemptions. With respect to redemption orders placed by the Company by 9:00 a.m. Eastern Time (or such other time as may be agreed by the parties from time to time) on the first Business Day following the Trade Date, the Fund or its designee will use its best efforts to initiate by wire transfer to the Company proceeds of such redemptions no later than the close of the Fedwire System on the next Business Day following the Trade Date.

1.2 Subject to Section 1.3, the Fund will redeem any full or fractional Shares of any Portfolio when requested by the Company on behalf of an Account at net asset value in accordance with the operational procedures mutually agreed to by the Fund and the Company from time to time and the provisions of the Prospectus of the Portfolios. The Fund shall make payment for such Shares in accordance with Section 1.4, but in no event shall payment be delayed for a greater period than is permitted by the 1940 Act (including any Rule or order of the SEC thereunder).

1.3 (a) The Company will not aggregate orders received from its Contract owners after close of the New York Stock Exchange (generally, 4:00 p.m. Eastern Time) (the “Close of Trading”) with orders received before the Close of Trading, and represents and warrants that its internal control structure concerning the processing and transmission of orders is suitably designed to prevent or detect on a timely basis orders received after the Close of Trading from being aggregated with orders received before the Close of Trading and to minimize errors that could result in late transmission of orders. Orders received by the Company before the Close of Trading are eligible to receive that Business Day’s net asset value, and Orders received by the Company after the Close of Trading are eligible to receive the next Business Day’s net asset value.

(b) Notwithstanding anything to the contrary in this Agreement, the Fund shall accept purchase and redemption orders resulting from investment in and payments under the Contracts on each Business Day, provided that such orders are received prior to 9:00 a.m. Eastern Time and reflect instructions received by the Company from Contract owners in good order prior to the time the net asset value of each Portfolio is priced in accordance with the preceding paragraph and the Fund’s Prospectus on the prior Business Day. “Business Day” shall mean any day on which the New York Stock Exchange is open for trading and on which the Fund calculates its net asset value pursuant to the rules of the SEC. Purchase and redemption orders shall be provided by the Company in such written or electronic form (including, without limitation, facsimile) as may be mutually acceptable to the Company and the Fund. The Fund may reject purchase and redemption orders which are not in the form prescribed in the Fund’s Prospectus. In the event that the Company and the Fund agree to use a form of written or electronic communication which is not capable of recording the time, date and recipient of any communication and confirming good transmission, the Company agrees that it shall be responsible for confirming that any communication sent by the Company was in fact received by the Fund or its designee, in proper form and in accordance with the terms of this Agreement. The Fund and its agents or designees shall be entitled to rely upon, and shall be fully protected from all liability in acting upon, the instructions of the authorized individuals.

1.4 Purchase orders that are transmitted to the Fund or its designee in accordance with Section 1.3 shall be paid for on the next Business Day following the Trade Date. Payments shall be made in federal funds transmitted by wire. In the event that the Company shall fail to pay in a timely manner for any purchase order validly received by the Fund or its designee pursuant to Section 1.3, the Company shall hold the Fund or its designee harmless from any losses reasonably sustained by the Fund or its designee as the result of acting in reliance on such purchase order. Redemption orders that are transmitted to the Fund or its designee in accordance with Section 1.3 shall be paid for no later than the close of the Fedwire System on the next Business Day after the Fund receives notice of the order. Payments shall be made in federal funds transmitted by wire. In the event that the Fund or its designee shall fail to pay in a timely manner for any redemption order validly received by the Fund or its designee pursuant to Section 1.3, the Fund or its designee shall hold the Company harmless from any losses reasonably sustained by the Company as the result of acting in reliance on such redemption order.

1.5 Issuance and transfer of Shares of the Portfolios will be by book entry only. Share certificates will not be issued to the Company or the Account. Shares ordered from the Fund will be recorded in the appropriate title for each Account or the appropriate sub-account of each Account.

1.6 The Fund agrees to provide the Company (via email or by a third party service such as Advisor Central), by 2:00pm Eastern Time on each Business Day, the total number of Portfolio Shares held by each Account as of the close of the immediately preceding Business Day.

1.7 The Fund or its designee shall furnish prompt written notice by email to the Company of any income, dividends or capital gain distribution payable on 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 Fund shall notify the Company in writing by email of the number of Shares so issued as payment of such income, dividends and distributions.

1.8 The Fund shall provide the Company via e-mail with a file that sets forth the net asset value per Share for each Portfolio, including dividend or daily accrual rate information and capital gain information 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 provide such file with such net asset value per Share, as well as dividends and capital gains information by 6:30 p.m. Eastern Time. If the Fund provides materially incorrect net asset value information, it shall make an adjustment to the number of Shares purchased or redeemed for any affected Account to reflect the correct net asset value. Any material error in the calculation or reporting of net asset value, dividend or capital gains information shall be reported promptly in writing by email upon discovery to the Company.

1.9 If there are corrections to a Portfolio’s net asset value, the determination of the materiality of any net asset value pricing error and its correction shall be based on the Fund’s guidelines regarding these errors. Any material error in the calculation or reporting of net asset value per share, dividend or capital gain information shall be reported promptly to the Company upon discovery. The Fund shall promptly reimburse the Company any amount owed under the Funds’ guidelines after the error is identified. Should a material miscalculation by the Fund or its agents result in a gain to the Company, the Company shall promptly reimburse

the Fund, the applicable Portfolios or its agents for any material losses incurred by the Fund, the applicable Portfolios or its agents as a result of the incorrect calculation. Should a material miscalculation by the Fund or its agents result in a gain to Contract owners, the Company will consult with the Fund or its designee as to what reasonable efforts shall be made to recover the money and repay the Fund, the applicable Portfolio or its agents. The Company shall then make such reasonable effort, at the expense of the Fund or its agents, to recover the money and repay the Fund, the applicable Portfolios or its agents; but the Company shall not be obligated to take legal action against Contract owners.

1.10 The Company agrees that it will not take any action to operate an Account as a management investment company under the 1940 Act without the Fund’s and the Underwriter’s prior written consent.

1.11 The Fund agrees that its Shares will be sold only to Participating Insurance Companies and their separate accounts. No Shares of any Portfolio will be sold directly to the general public. The Company agrees that Shares will be used only for the purposes of funding the Contracts and Accounts listed in Schedule A, as amended from time to time.

1.12 The Fund agrees that all Participating Insurance Companies shall have the obligations and responsibilities regarding conflicts of interest corresponding to those contained in Article 4 of this Agreement.

1.13 The Fund reserves the right to reject any purchase orders, including exchanges, for any reason, including if the Fund, in its sole opinion, believes any of the Company’s Contract owners is engaging in short-term or excessive trading into and out of a Portfolio or otherwise engaging in trading that may be disruptive to a Portfolio (“Market Timing”). The Company agrees that it will cooperate with the Underwriter and the Fund to monitor for Market Timing by Contract owners, to provide such relevant information about Market Timing to the Fund as it may reasonably request, including but not limited to such Contract owner’s identity, and to prevent Market Timing from occurring by or because of Contract owners. Failure of the Fund to reject any purchase orders that might be deemed to be Market Timing shall not constitute a waiver of the Fund’s rights under this section. Pursuant to Rule 22c-2 of the 1940 Act, on behalf of the Fund, the Underwriter and the Company agree that the Company will comply with the terms included in the attached Schedule C as of the effective date of this Agreement.

In addition, Insurer shall have a designated anti-money laundering compliance officer, and Insurer shall provide anti-money laundering training to its staff on an annual basis. Finally, Insurer’s anti-money laundering program shall provide for an independent audit of its anti-money laundering program on an annual basis. Insurer and BRIL will promptly inform each other in writing if Insurer or BRIL become aware of any violations of anti-money laundering laws by it or any of its Contract owners or if Insurer or BRIL is otherwise unable to comply with its obligations under this Section 3.9.

Insurer also agrees to provide BRIL with such information as it may reasonably request, including, but not limited to, the filling out of questionnaires, attestations and other documents, to enable the Fund and the Underwriter to fulfill their obligations under applicable Sanctions Laws and the USA PATRIOT ACT (including maintaining records for at least five years).

3.10 The Company acknowledges and agrees that it is the responsibility of the Company to determine investment restrictions under state insurance law applicable to any Portfolio, and that the Fund shall bear no responsibility to the Company for any such determination or the correctness of such determination. The Company has determined that the investment restrictions set forth in the current Prospectus are sufficient to comply with all investment restrictions under state insurance laws that are currently applicable to the Portfolios as a result of the Accounts’ investment therein. The Company shall inform the Fund of any additional investment restrictions imposed by state insurance law after the date of this Agreement that may become applicable to the Fund or any Portfolio from time to time as a result of the Accounts’ investment therein. Upon receipt of any such information from the Company, the Fund shall determine whether it is in the best interests of shareholders to comply with any such restrictions. If the Fund determines that it is not in the best interests of shareholders to comply with a restriction determined to be applicable by the Company, the Fund shall so inform the Company, and the Fund and the Company shall discuss alternative accommodations in the circumstances.

3.11 The Company represents and warrants that each Account is a “segregated asset account” and that interests in each Account are offered exclusively through the purchase of or transfer into a “variable contract,” within the meaning of such terms under Section 817 of the Code and the regulations thereunder. The Company will use its best efforts to continue to meet such definitional requirements, and it will notify the Fund immediately upon having a reasonable basis for believing that such requirements have ceased to be met or that they might not be met in the future.

ARTICLE 4

Potential Conflicts

4.1 The parties acknowledge that the Fund’s Shares may be made available for investment to other Participating Insurance Companies. In such event, the Directors of the Fund will monitor the Fund for the existence of any material irreconcilable conflict between the interests of the contract owners of all Participating Insurance Companies. A material irreconcilable 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 a Participating Insurance Company to disregard the voting instructions of contract owners. The Directors shall promptly inform the Company in writing if they determine that an irreconcilable material conflict exists and the implications thereof.

4.2 The Company agrees that it will promptly report any potential or existing conflicts of which it is aware to the Directors. The Company will assist the Directors in carrying out their responsibilities under the Shared Fund Exemptive Order by providing the Directors with all information reasonably necessary for them 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 Directors, or a majority of the Directors who are not affiliated with BAL or the Underwriter (the “Disinterested Directors”), 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 Directors) 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 Fund or any Portfolio and reinvesting such assets in a different investment medium, including (but not limited to) another Portfolio of the Fund, 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 Fund’s election, to withdraw the affected Account’s investment in the Fund 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 Directors. Any such withdrawal and termination must take place within 30 days after the Fund gives written notice that this provision is being implemented, subject to applicable law but in any event consistent with the terms of the Shared Fund Exemptive Order. Until the end of such 30 day period, the Fund shall continue to accept and implement orders by the Company for the purchase and redemption of Shares.

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 Fund and terminate this Agreement with respect to such Account within 30 days after the Fund 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 Directors. Until the end of such 30 day period, the Fund shall continue to accept and implement orders by the Company for the purchase and redemption of Shares.

4.6 For purposes of section 4.3 through 4.6 of this Agreement, a majority of the Disinterested Directors 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 Directors determine that any proposed action does not adequately remedy any irreconcilable material conflict, then the Company will withdraw the Account’s investment in the Fund and terminate this Agreement within 30 days after the Directors 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 Directors.

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

4.8 If and to the extent that (a) 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 application for the Shared Fund Exemptive Order) on terms and conditions materially different from those contained in the application for the Shared Fund Exemptive Order, or (b) the Shared Fund Exemptive Order is granted on terms and conditions that differ from those set forth in this Article 4, then the Fund and/or the Participating Insurance Companies, as appropriate, shall take such steps as may be necessary (a) 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, or (b) to conform this Article 4 to the terms and conditions contained in the Shared Fund Exemptive Order, as the case may be.

ARTICLE 5

Indemnification

5.1 The Company agrees to indemnify and hold harmless the Fund Parties and each of their respective Directors, officers, employees and agents and each person, if any, who controls a Fund Party within the meaning of Section 15 of the 1933 Act (collectively the “Indemnified Parties” for purposes of this Section 5.1) 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 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 common law or otherwise, insofar as such Losses:

(a) arise out of or are based upon any untrue statements or untrue statements of any material fact contained in the registration statement, prospectus(es) or statements of additional information for the Contracts or in the Contracts themselves or in sales literature or other promotional material generated or approved by the Company on behalf of the Contracts or Accounts (or any amendment or supplement to any of the foregoing) (collectively, “Company Documents” for the purposes of this Article 5), or arise out of or are based upon the 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 was made in reliance upon and was accurately derived from written information furnished to the Company by or on behalf of the Fund or Underwriter for use in Company Documents or otherwise for use in connection with the sale of the Contracts or Shares; or

(b) arise out of or result from statements or representations (other than statements or representations contained in and accurately derived from Fund Documents as defined in Section 5.2(a)) or wrongful conduct of the Company or persons under its control, with respect to the sale or acquisition of the Contracts or Shares; or

(c) arise out of or result from any untrue statement of a material fact contained in Fund Documents as defined in Section 5.2(a) or the omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading if such

statement or omission was made in reliance upon and accurately derived from written information furnished to the Fund or Underwriter by or on behalf of the Company; or

(d) arise out of or result from any failure by the Company to provide the services or furnish the materials required under the terms of this Agreement; or

(e) arise out of or result from any material breach of any representation and/or warranty made by the Company in this Agreement or any Related Agreement or arise out of or result from any other material breach of this Agreement or any Related Agreement by the Company.

5.2 The Underwriter and the Fund agree severally to indemnify and hold harmless the Company and each of its directors, officers, employees and agents and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act (collectively, the “Indemnified Parties” for purposes of this Section 5.2) against any and all losses, claims, damages, liabilities (including amounts paid in settlement with the written consent of the Fund Parties) or expenses (including the reasonable costs of investigating or defending any 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 of any material fact contained in the registration statement or Prospectus for the Fund (or any amendment or supplement thereto) (collectively, “Fund Documents” for the purposes of this Article 5), or arise out of or are based upon the 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 was made in reliance upon and was accurately derived from written information furnished to the Fund Parties by or on behalf of the Company for use in Fund Documents or otherwise for use in connection with the sale of the Contracts or Shares; or

(b) arise out of or result from statements or representations (other than statements or representations contained in and accurately derived from Company Documents) or wrongful conduct of a Fund Party or persons under its respective control, with respect to the sale or acquisition of the Contracts or Shares; or

(c) arise out of or result from any untrue statement of a material fact contained in Company Documents or the omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading if such statement or omission was made in reliance upon and accurately derived from written information furnished to the Company by or on behalf of the Fund Parties; or

(d) arise out of or result from any material breach of any representation and/or warranty made by the Underwriter or the Fund in this Agreement or any Related Agreement or arise out of or result from any other material breach of this Agreement or any Related Agreement by the Underwriter or the Fund.

5.3 Neither the Company, the Underwriter nor the Fund shall be liable under the indemnification provisions of Section 5.1 or 5.2, as applicable, with respect to any Losses incurred or assessed against any Indemnified Party to the extent such Losses arise out of or result 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.

5.4 Neither the Company, the Underwriter nor the Fund 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 parties 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.

5.5 In case any such action is brought against the Indemnified Parties, the indemnifying party shall be entitled to participate, at its own expense, in the defense of such action. The indemnifying party also shall be entitled to assume the defense thereof, with counsel reasonably satisfactory to the party named in such action. After notice from the indemnifying party to the Indemnified Party of an election to assume such defense, the Indemnified Party shall bear the fees and expenses of any additional counsel retained by it, and the indemnifying party will not be liable to the Indemnified 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. Neither party shall admit to wrong-doing nor make any compromise in any action or proceeding which may result in a finding of wrongdoing by the other party without the other party’s prior written consent, which shall not be unreasonably withheld. Any notice given by the indemnifying party to an indemnified party in or control of the litigation of any such claim by the indemnifying party shall in no event be deemed to be an admission by the indemnifying party of culpability, and the indemnifying party shall be free to contest liability among the parties with respect to the claim.

ARTICLE 6

Termination

6.1 This Agreement may be terminated by any party for any reason by sixty (60) days’ advance written notice to the other parties.

6.2 This Agreement may be terminated immediately upon written notice to the other parties at the option of either the Underwriter or the Fund upon institution of formal proceedings against the Company by FINRA, the SEC, the insurance commission of any state or any other regulatory body regarding the Company’s duties under this Agreement or related to the sale of the Contracts, the operation of the Account(s), the administration of the Contracts or the purchase of the Shares, or an expected or anticipated ruling, judgment or outcome which would, in the Fund’s or the Underwriter’s respective reasonable judgment, materially impair the Company’s ability to meet and perform the Company’s obligations and duties hereunder.

6.3 This Agreement may be terminated immediately upon written notice to the other parties at the option of the Fund or the Underwriter if the Internal Revenue Service determines that the Contracts cease to qualify as annuity contracts or life insurance policies, as applicable, under the Code, or if the Fund or Underwriter reasonably believes that the Contracts may fail to so qualify or if interests in an Account under the Contracts are not registered, where required, and, in all material respects, are not issued or sold in accordance with any applicable federal or state law.

6.4 This Agreement may be terminated immediately upon written notice to the other parties by the Fund or the Underwriter, at either’s option, if either the Fund or the Underwriter shall determine, in its sole judgment exercised in good faith, that either (1) the Company shall have suffered a material adverse change in its business or financial condition, (2) the Company shall have been the subject of material adverse publicity which is likely to have a material adverse impact upon the business and operations of either the Fund or the Underwriter, or (3) the Company breaches any obligation under this Agreement or any Related Agreement in a material respect and such breach shall continue unremedied for thirty (30) days after receipt by the Company of notice in writing from the Fund or Underwriter of such breach.

6.5 This Agreement may be terminated immediately upon written notice to the other parties at the option of the Company if (A) the Internal Revenue Service determines that any Portfolio fails to qualify as a RIC under the Code or fails to comply with the diversification requirements of Section 817(h) of the Code and the Fund, upon written request fails to provide reasonable assurance that it will take action to cure such failure, or (B) the Company shall determine, in its sole judgment exercised in good faith, that either (1) the Fund or the Underwriter shall have been the subject of material adverse publicity which is likely to have a material adverse impact upon the business and operations of the Company, or (2) the Fund or Underwriter breaches any obligation under this Agreement or any Related Agreement in a material respect and such breach shall continue unremedied for thirty (30) days after receipt of notice in writing to the Fund or the Underwriter from the Company of such breach.

6.6 Notwithstanding any termination of this Agreement, the Fund and the Underwriter may continue to make available additional Shares of the Portfolios of the Fund pursuant to the terms and conditions of this Agreement, for all existing Contracts in effect on the effective date of termination of this Agreement (hereinafter referred to as “Existing Contracts”). Specifically, without limitation, if the Fund and Underwriter so agree to make additional Shares available, the owners of the Existing Contracts will be permitted to reallocate investments in the Fund (as in effect on such date), redeem investments in the Fund and/or invest in the Fund upon the making of additional purchase payments under the Existing Contracts. In the event of a termination of this Agreement pursuant to this Article 6, the Fund and the Underwriter shall promptly notify the Company in writing whether the Underwriter and the Fund will continue to make Shares available to Existing Contracts after such termination; if the Underwriter and the Fund will continue to make Shares so available, the provisions of this Agreement shall remain in effect with respect to transactions in Shares by such Existing Contracts except for Section 6.1 and thereafter either the Fund, Underwriter or the Company may terminate the Agreement as so continued pursuant to this Section 6.6 upon prior written notice to the other parties, such notice to be for a period that is reasonable under the circumstances but need not be greater than six months.

6.7 The provisions of Section 2.11, Articles 5, 7 and 8 and Section 10 of Schedule C shall survive the termination of this Agreement, and the provisions of Articles 2 and 4 shall survive the termination of this Agreement as long as Shares of the Fund are held on behalf of Contract owners.

ARTICLE 7

Schedule C

Shareholder Information Schedule entered into by and between BlackRock Investments, LLC and its successors, assigns and designees (“BRIL”) and the Intermediary.

For Schedule C, the following terms shall have the following meanings, unless a different meaning is clearly required by the contexts:

The term “Intermediary” shall mean Massachusetts Mutual Life Insurance Company, which is (i) a broker, dealer, bank, or other entity that holds securities of record issued by the Fund in nominee name; (ii) in the case of a participant directed employee benefit plan that owns securities issued by the Fund (1) a retirement plan administrator under ERISA or (2) any entity that maintains the plan’s participant records; or (iii) an insurance company separate account.

The term “Fund” shall mean any open-ended management investment company that is registered or required to register under Section 8 of the Investment Company Act of 1940 and for which BRIL acts as distributor, and includes (i) an investment adviser to or administrator for the Fund; and (ii) the transfer agent for the Fund. The term does not include any “excepted funds” as defined in SEC Rule 22c-2(b) under the Investment Company Act of 1940.¹
