WHEREAS, LIFE COMPANY will be the issuer of certain variable annuity contracts and/or variable life insurance contracts (“Contracts”) as set forth on Schedule A hereto, as the Parties hereto may amend from time to time, which Contracts (hereinafter collectively, the “Contracts”), if required by applicable law, will be registered under the 1933 Act; and

NOW, THEREFORE, in consideration of the mutual benefits and promises contained herein, the Parties hereto agree as follows:

Section 1. Available Funds

1.1 Availability.

SMFI will make Shares of each Fund available to LIFE COMPANY for purchase and redemption at net asset value and with no sales charges, subject to the terms and conditions of this Agreement. Shares of a Fund may be subject to distribution expenses under Rule 12b-1 under the 1940 Act. The Board of Directors of SMFI 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 if, in the sole discretion of the Directors acting in good faith and in light of their fiduciary duties under federal and any applicable state laws, such action is deemed in the best interests of the shareholders of such Fund.

1.2 Addition, Deletion or Modification of Funds.

The Parties hereto may agree, from time to time, to add other Funds to provide additional funding media for the Contracts, or to delete, combine, or modify existing Funds, by amending Schedule A hereto. Upon such amendment to Schedule A, any applicable reference to a Fund, SMFI, or its Shares herein shall include a reference to any such additional Fund. Schedule A, as amended from time to time, is incorporated herein by reference and is a part hereof.

1.3 No Sales to the General Public.

SMFI represents and warrants that no Shares of any Fund have been or will be sold to the general public, it being understood by the Parties that SMFI may sell shares of any Fund to any insurance companies and their separate accounts and to qualified persons or plans (“Qualified Persons”) that qualify and are eligible to invest in that Fund in accordance with applicable provisions of Section 817(h) of the Code and the regulations thereunder, the sale of which will not impair the tax treatment currently afforded the Contracts.

Section 2 Processing Transactions

2.1 Timely Pricing and Orders.

(a) SMFI or its designated agent will use its best efforts to provide LIFE COMPANY with the net asset value per Share for each Fund by 6:30 p.m. Eastern Standard Time on each Business Day. As used herein, “Business Day” shall mean any day on which (i) the New York

- 5 -

Stock Exchange is open for regular trading (ii) SMFI calculates the Fund’s net asset value, and (iii) LIFE COMPANY is open for business.

(b) LIFE COMPANY will use the data provided by SMFI each Business Day pursuant to paragraph (a) immediately above to calculate Account unit values and to process transactions that receive that same Business Day’s Account unit values. LIFE COMPANY will perform such Account processing the same Business Day, and will place corresponding orders to purchase or redeem Shares with SMFI by 9:30 a.m. Eastern Standard Time the following Business Day; provided, however, that SMFI shall provide additional time to LIFE COMPANY in the event that SMFI is unable to meet the 6:30 p.m. time stated in paragraph (a) immediately above. Such additional time shall be equal to the additional time that SMFI takes to make the net asset values available to LIFE COMPANY.

(c) With respect to payment of the purchase price by LIFE COMPANY and of redemption proceeds by SMFI, LIFE COMPANY and SMFI shall net purchase and redemption orders with respect to each Fund and shall transmit one net payment per Fund in accordance with Section 2.2, below.

(d) If SMFI provides materially incorrect Share net asset value information (as determined under SEC guidelines), LIFE COMPANY shall be entitled to an adjustment to the number of Shares purchased or redeemed to reflect the correct net asset value per Share, and any reasonable out-of-pocket expenses incurred by the LIFE COMPANY in adjusting the Share net asset value. Any material error in the calculation or reporting of net asset value per Share, dividend or capital gain information shall be reported promptly upon discovery to LIFE COMPANY.

2.2 Timely Payments.

LIFE COMPANY will wire payment for net purchases to a custodial account designated by SMFI by 2:00 p.m. Eastern Standard Time on the same day as the order for Shares is placed, to the extent practicable. SMFI will wire payment for net redemptions to an account designated by LIFE COMPANY by 2:00 p.m. Eastern Standard Time on the same day as the Order is placed, to the extent practicable, but in any event within five (5) calendar days after the date the order is placed in order to enable LIFE COMPANY to pay redemption proceeds within the time specified in Section 22(e) of the 1940 Act or such shorter period of time as may be required by law.

2.3 Applicable Price.

(a) Share purchase payments and redemption orders that result from purchase payments, premium payments, surrenders and other transactions under Contracts (collectively, “Contract transactions”) and that LIFE COMPANY receives prior to the close of regular trading on the New York Stock Exchange on a Business Day will be executed at the net asset values of the appropriate Funds next computed after receipt by SMFI or its designated agent of the orders. For purposes of this Section 2.3(a), LIFE COMPANY shall be the designated agent of SMFI for receipt of orders relating to Contract transactions on each Business Day and receipt by such designated agent shall constitute receipt by SMFI; provided that SMFI receives notice of such

- 6 -

orders by 9:30 a.m. Eastern Standard Time on the next following Business Day or such later time as computed in accordance with Section 2.1 (b) hereof.

(b) All other Share purchases and redemptions by LIFE COMPANY will be effected at the net asset values of the appropriate Funds next computed after receipt by SMFI or its designated agent of the order therefor, and such orders will be irrevocable.

2.4 Dividends and Distributions.

SMFI will furnish notice by wire or telephone (followed by written confirmation) on or prior to the payment date to LIFE COMPANY of any income dividends or capital gain distributions payable on the Shares of any Fund. LIFE COMPANY hereby elects to reinvest all dividends and capital gains distributions in additional Shares of the corresponding Fund at the ex-dividend date net asset values until LIFE COMPANY otherwise notifies SMFI in writing, it being agreed by the Parties that the ex-dividend date and the payment date with respect to any dividend or distribution will be the same Business Day. LIFE COMPANY reserves the right to revoke this election and to receive all such income dividends and capital gain distributions in cash.

2.5 Book Entry.

Issuance and transfer of SMFI Shares will be by book entry only. Stock certificates will not be issued to LIFE COMPANY. Shares ordered from SMFI will be recorded in an appropriate title for LIFE COMPANY, on behalf of its Account.

Section 3. Costs and Expenses

3.1 General.

Except as otherwise specifically provided in Schedule C, attached hereto and made a part hereof, each Party will bear all expenses incident to its performance under this Agreement.

3.2 Parties To Cooperate.

Section 4. Legal Compliance

4.1 Tax Laws.

(a) SMFI represents and warrants that each Fund is currently qualified as a regulated investment company (“RIC”) under Subchapter M of the Internal Revenue Code of 1986, as amended (the “Code”), and represents that it will use its best efforts to qualify and to maintain qualification of each Fund as a RIC.

(d) LIFE COMPANY represents and warrants that the Contracts currently are and will be treated as annuity contracts or life insurance contracts under applicable provisions of the Code and that it will use its best efforts to maintain such treatment; LIFE COMPANY will notify SMFI promptly upon having a reasonable basis for believing that any of the Contracts have ceased to be so treated or that they might not be so treated in the future.

(e) LIFE 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.

Section 5. Mixed and Shared Funding

5.1 General.

SMFI has received an order from the SEC exempting it from certain provisions of the 1940 Act and rules thereunder so that SMFI may be available for investment by certain other entities, including, without limitation, separate accounts funding variable annuity contracts or variable life insurance contracts, separate accounts of insurance companies unaffiliated with LIFE COMPANY, and trustees of qualified pension and retirement plans (collectively, “Mixed and Shared Funding”). The Parties recognize that the SEC has imposed terms and conditions for such orders that are substantially identical to many of the provisions of this Section 5. Sections 5.2 through 5.8 below shall apply pursuant to such an exemptive order granted to SMFI. SMFI hereby notifies LIFE COMPANY that it may be appropriate to include in the prospectus pursuant to which a Contract is offered disclosure regarding the potential risks of Mixed and Shared Funding.

5.2 Disinterested Directors.

SMFI agrees that its Board of Directors shall at all times consist of directors a majority of whom (the “Disinterested Directors”) are not interested persons of SMFI within the meaning of Section 2(a)(19) of the 1940 Act and the rules thereunder and as modified by any applicable orders of the SEC, except that if this condition is not met by reason of the death, disqualification, or bona fide resignation of any director, then the operation of this condition shall be suspended (a) for a period of forty-five (45) days if the vacancy or vacancies may be filled by the Board; (b) for a period of sixty (60) days if a vote of shareholders is required to fill the vacancy or vacancies; or (c) for such longer period as the SEC may prescribe by order upon application.

5.3 Monitoring for Material Irreconcilable Conflicts.

SMFI agrees that its Board of Directors will monitor for the existence of any material irreconcilable conflict between the interests of the Contractholders in all separate accounts of life insurance companies utilizing SMFI (“Participating Insurance Companies”), including each Account, and participants in all qualified retirement and pension plans investing in SMFI (“Participating Plans”). LIFE COMPANY agrees to inform the Board of Directors of SMFI of the existence of any such material irreconcilable conflict of which it is aware. The concept of a “material irreconcilable conflict” is not defined by the 1940 Act or the rules thereunder, but the

- 13 -

Parties recognize that such a conflict may arise for a variety of reasons, including, without limitation:

(a) an action by any state insurance or other 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 Contractholders or by Contractholders of different Participating Insurance Companies;

(f) a decision by a Participating Insurance Company to disregard the voting instructions of Contractholders; or

(g) a decision by a Participating Plan to disregard the voting instructions of Plan participants.

Consistent with the SEC’s requirements in connection with exemptive orders of the type referred to in Section 5.1 hereof, LIFE COMPANY will assist the Board of Directors in carrying out its responsibilities by providing the Board of Directors with all information reasonably necessary for the Board of Directors to consider any issue raised, including information as to a decision by LIFE COMPANY to disregard voting instructions of Contractholders. LIFE COMPANY’s responsibilities in connection with the foregoing shall be carried out with a view only to the interests of Contractholders.

5.4 Conflict Remedies.

(a) It is agreed that if it is determined by a majority of the members of the Board of Directors or a majority of the Disinterested Directors that a material irreconcilable conflict exists, LIFE COMPANY will, if it is a Participating Insurance Company for which a material irreconcilable conflict is relevant, at its own expense and to the extent reasonably practicable (as determined by a majority of the Disinterested Directors), take whatever steps are necessary to remedy or eliminate the material irreconcilable conflict, which steps may include, but are not limited to:

(i) withdrawing the assets allocable to some or all of the Accounts from SMFI or any Fund and reinvesting such assets in a different investment medium, including another Fund of SMFI, or submitting the question whether such segregation should be implemented to a vote of all affected Contractholders and, as appropriate, segregating the assets of any particular group (e.g., annuity Contractholders, life insurance Contractholders) that votes in favor of such

- 14 -

segregation, or offering to the affected Contractholders the option of making such a change; and

(ii) establishing a new registered investment company of the type defined as a “management company” in Section 4(3) of the 1940 Act or a new separate account that is operated as a management company.

(b) If the material irreconcilable conflict arises because of LIFE COMPANY’s decision to disregard Contractholders voting instructions and that decision represents a minority position or would preclude a majority vote, LIFE COMPANY may be required, at SMFI’s election, to withdraw each Account’s investment in SMFI or any Fund. No charge or penalty will be imposed as a result of such withdrawal. Any such withdrawal must take place within six (6) months after SMFI gives notice to LIFE COMPANY that this provision is being implemented, and until such withdrawal SMFI shall continue to accept and implement orders by LIFE COMPANY for the purchase and redemption of Shares of SMFI.

(c) If a material irreconcilable conflict arises because a particular state insurance regulator’s decision applicable to LIFE COMPANY conflicts with the majority of other state regulators, then LIFE COMPANY will withdraw each Account’s investment in SMFI within six (6) months after SMFI’s Board of Directors informs LIFE COMPANY that it has determined that such decision has created a material irreconcilable conflict, and until such withdrawal SMFI shall continue to accept and implement orders by LIFE COMPANY for the purchase and redemption of Shares of SMFI. No charge or penalty will be imposed as a result of such withdrawal.

(d) LIFE COMPANY agrees that any remedial action taken by it in resolving any material irreconcilable conflict will be carried out at its expense and with a view only to the interests of Contractholders.

(e) For purposes hereof, a majority of the Disinterested Directors will determine whether or not any proposed action adequately remedies any material irreconcilable conflict. In no event, however, will SMFI or any of its affiliates be required to establish a new funding medium for any Contracts. LIFE COMPANY will not be required by the terms hereof to establish a new funding medium for any Contracts if an offer to do so has been declined by vote of a majority of Contractholders materially adversely affected by the material irreconcilable conflict.

5.5 Notice to LIFE COMPANY.

SMFI will promptly make known in writing to LIFE COMPANY the Board of Directors’ determination of the existence of a material irreconcilable conflict, a description of the facts that give rise to such conflict and the implications of such conflict.

5.6 Information Requested by Board of Directors.

LIFE COMPANY and SMFI (or its investment adviser) will at least annually submit to the Board of Directors of SMFI such reports, materials or data as the Board of Directors may reasonably request so that the Board of Directors may fully carry out the obligations imposed

- 15 -

upon it by the provisions hereof or any exemptive order granted by the SEC to permit Mixed and Shared Funding, and said reports, materials and data will be submitted at any reasonable time deemed appropriate by the Board of Directors. All reports received by the Board of Directors of potential or existing conflicts, and all Board of Directors actions with regard to determining the existence of a conflict, notifying Participating Insurance Companies and Participating Plans of a conflict, and determining whether any proposed action adequately remedies a conflict, will be properly recorded in the minutes of the Board of Directors or other appropriate records, and such minutes or other records will be made available to the SEC upon request.

5.7 Compliance with SEC Rules.

If, at any time during which SMFI is serving as an investment medium for variable life insurance Contracts, 1940 Act Rules 6e-3(T) or, if applicable, 6e-2 are amended or Rule 6e-3 is adopted to provide exemptive relief with respect to Mixed and Shared Funding, SMFI agrees that it will comply with the terms and conditions thereof and that the terms of this Section 5 shall be deemed modified if and only to the extent required in order also to comply with the terms and conditions of such exemptive relief that is afforded by any of said rules that are applicable.

5.8 Other Requirements.

SMFI will require that each Participating Insurance Company and Participating Plan enter into an agreement with SMFI that contains in substance the same provisions as are set forth in Sections 4.1 (b), 4.1(d), 4.3(a), 4.4(b), 4.5(a), 5, and 10 of this Agreement.

(d) at the option of any Party in the event that (i) the Fund’s Shares are not registered, where required, and, in all material respects, issued and sold in accordance with any applicable federal or state law, or (ii) such law precludes the use of such Shares as an underlying investment medium of the Contracts issued or to be issued by LIFE COMPANY; or

(i) upon another Party’s material breach of any provision of this Agreement.

6.2 Notice Requirement for Termination.

No termination of this Agreement will be effective unless and until the Party terminating this Agreement gives prior written notice to the other Party to this Agreement of its intent to terminate, and such notice shall set forth the basis for such termination. Furthermore:

Such steps may include combining the affected Account with another Account, substituting other mutual fund shares for those of the affected Fund, or otherwise terminating participation by the Contracts in such Fund.

Section 10. Voting Procedures

Subject to the cost allocation procedures set forth in Section 3 and Schedule C hereof, LIFE COMPANY will cooperate with SMFI and AIC in distributing one set per year of proxy material furnished by SMFI to Contractholders to whom pass-through voting privileges are required to be extended and will solicit voting instructions from Contractholders. The Parties agree that any additional distributions shall require special arrangements and any related costs shall be the responsibility of SMFI. LIFE COMPANY will vote Shares in accordance with timely instructions received from Contractholders. LIFE COMPANY will vote Shares that are (a) not attributable to Contractholders to whom pass-through voting privileges are extended, or (b) attributable to Contractholders, but for which no timely instructions have been received, in the same proportion as Shares for which said instructions have been received from Contractholders, so long as and to the extent that the SEC continues to interpret the 1940 Act to require pass through voting privileges for Contractholders. Neither LIFE COMPANY nor any of its affiliates will in any way recommend action in connection with or oppose or interfere with the

- 19 -

solicitation of proxies for the Shares held for such Contractholders. LIFE COMPANY reserves the right to vote shares held in any Account in its own right, to the extent permitted by law. LIFE COMPANY shall be responsible for assuring that each of its Accounts holding Shares calculates voting privileges in a manner consistent with that of other Participating Insurance Companies or in the manner required by the Mixed and Shared Funding exemptive order obtained by SMFI. SMFI will notify LIFE COMPANY of any changes of interpretations or amendments to Mixed and Shared Funding exemptive order it obtains. SMFI will comply with all provisions of the 1940 Act requiring voting by shareholders, and in particular, SMFI either will provide for annual meetings (except insofar as the SEC may interpret Section 16 of the 1940 Act not to require such meetings) or will comply with Section 16(c) of the 1940 Act (although SMFI is not one of the trusts described in Section 16(c) of that Act) as well as with Sections 16(a) and, if and when applicable, 16(b). Further, SMFI will act in accordance with the SEC’s interpretation of the requirements of Section 16(a) with respect to periodic elections of directors and with whatever rules the SEC may promulgate with respect thereto.

Section 11. Foreign Tax Credits

SMFI agrees to consult in advance with LIFE COMPANY concerning any decision to elect or not to elect pursuant to Section 853 of the Code to pass through the benefit of any foreign tax credits to its shareholders.

Section 12. Indemnification

12.1 Of SMFI and AIC by LIFE COMPANY AND UNDERWRITER.

(a) Except to the extent provided in Sections 12.1(b) and 12.1(c), below, LIFE COMPANY agrees to indemnify and hold harmless SMFI, AIC, their affiliates, and each person, if any, who controls SMFI, AIC, or their affiliates within the meaning of Section 15 of the 1933 Act and each of their respective directors and officers, (collectively, the “Indemnified Parties” for purposes of this Section 12.1) against any and all losses, claims, damages, liabilities (including amounts paid in settlement with the written consent of LIFE COMPANY) or actions in respect thereof (including, to the extent reasonable, 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 actions:

(i) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any Contracts’s 1933 Act registration statement, any Contract Prospectus, the Contracts, or sales literature or advertising 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 LIFE COMPANY or UNDERWRITER by or on behalf of SMFI or AIC for use in any Contract’s 1933 Act, registration

- 20 -

statement, any Contract Prospectus, the Contracts, or sales literature or advertising or otherwise for use in connection with the sale of Contracts or Shares (or any amendment or supplement to any of the foregoing); or

(ii) arise out of or as a result of any other statements or representations (other than statements or representations contained in SMFI’s 1933 Act registration statement, SMFI Prospectus, sales literature or advertising of SMFI, or any amendment or supplement to any of the foregoing, not supplied for use therein by or on behalf of LIFE COMPANY, UNDERWRITER or their respective affiliates and on which such persons have reasonably relied) or the negligent, illegal or fraudulent conduct of LIFE COMPANY, UNDERWRITER or their respective affiliates or persons under their control (including, without limitation, their employees and “Associated Persons,” as that term is defined in paragraph (m) of Article I of FINRA’s By-Laws), in connection with the sale or distribution of the Contracts or Shares; or

(iii) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in SMFI’s 1933 Act registration statement, SMFI Prospectus, sales literature or advertising of SMFI, or any amendment or supplement to any of the foregoing, 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 SMFI, AIC or their affiliates by or on behalf of LIFE COMPANY, UNDERWRITER or their respective affiliates for use in SMFI’s 1933 Act registration statement, SMFI Prospectus, sales literature or advertising of SMFI, or any amendment or supplement to any of the foregoing; or

(iv) arise as a result of any failure by LIFE COMPANY or UNDERWRITER to perform the obligations, provide the services and furnish the materials required of them under the terms of this Agreement, or any material breach of any representation and/or warranty made by LIFE COMPANY or UNDERWRITER in this Agreement or arise out of or result from any other material breach of this Agreement by LIFE COMPANY or UNDERWRITER; or

(v) arise as a result of failure by the Contracts issued by LIFE COMPANY to qualify as annuity contracts or life insurance contracts under the Code, otherwise than by reason of any Fund’s failure to comply with Subchapter M or Section 817(h) of the Code.

(b) LIFE COMPANY shall not be liable under this Section 12.1 with respect to any losses, claims, damages, liabilities or actions to which an Indemnified Party would otherwise be subject by reason of willful misfeasance, bad faith, or gross negligence in the performance by

- 21 -

that Indemnified Party of its duties or by reason of that Indemnified Party’s reckless disregard of obligations or duties under this Agreement.

(c) LIFE COMPANY shall not be liable under this Section 12.1 with respect to any action against an Indemnified Party unless SMFI or AIC shall have notified LIFE COMPANY in writing within a reasonable time after the summons or other first legal process giving information of the nature of the action 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 LIFE COMPANY of any such action shall not relieve LIFE COMPANY from any liability which they may have to the Indemnified Party against whom such action is brought otherwise than on account of this Section 12.1. Except as otherwise provided herein, in case any such action is brought against an Indemnified Party, LIFE COMPANY shall be entitled to participate, at their own expense, in the defense of such action and also shall be entitled to assume the defense thereof, with counsel approved by the Indemnified Party named in the action, which approval shall not be unreasonably withheld. After notice from LIFE COMPANY to such Indemnified Party of LIFE COMPANY’s election to assume the defense thereof, the Indemnified Party will cooperate fully with LIFE COMPANY and shall bear the fees and expenses of any additional counsel retained by it, and LIFE COMPANY will not be liable to such Indemnified Party under this Agreement for any legal or other expenses subsequently incurred by such Indemnified Party independently in connection with the defense thereof, other than reasonable costs of investigation.

12.2 Of LIFE COMPANY and UNDERWRITER by SMFI and AIC.

(a) Except to the extent provided in Sections 12.2(c), 12.2(d) and 12.2(e), below, SMFI and AIC agree to indemnify and hold harmless LIFE COMPANY, its affiliates, and each person, if any, who controls LIFE COMPANY, or its affiliates within the meaning of Section 15 of the 1933 Act and each of their respective directors and officers, (collectively, the “Indemnified Parties” for purposes of this Section 12.2) against any and all losses, claims, damages, liabilities (including amounts paid in settlement with the written consent of SMFI and/or AIC) or actions in respect thereof (including, to the extent reasonable, 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 actions:

(i) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in SMFI’s 1933 Act registration statement, SMFI Prospectus or sales literature or advertising of SMFI (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 SMFI or its affiliates by or on behalf of LIFE COMPANY, UNDERWRITER or their respective affiliates for use in SMFI’s 1933 Act registration statement, SMFI Prospectus, or in sales literature or advertising or otherwise for use

- 22 -

in connection with the sale of Contracts or Shares (or any amendment or supplement to any of the foregoing); or

(ii) arise out of or as a result of any other statements or representations (other than statements or representations contained in any Account’s 1933 Act registration statement, any Account Prospectus, sales literature or advertising for the Contracts, or any amendment or supplement to any of the foregoing, not supplied for use therein by or on behalf of SMFI, AIC or their affiliates and on which such persons have reasonably relied) or the negligent, illegal or fraudulent conduct of SMFI, AIC or their affiliates or persons under their control (including, without limitation, their employees and “Associated Persons” as that term is defined in Section (m) of Article I of FINRA’s By-Laws), in connection with the sale or distribution of SMFI Shares; or

(iii) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any Contract’s 1933 Act registration statement, any Contract Prospectus, sales literature or advertising covering the Contracts, or any amendment or supplement to any of the foregoing, 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 statement or omission was made in reliance upon and in conformity with information furnished to LIFE COMPANY, UNDERWRITER or their respective affiliates by or on behalf of SMFI or AIC for use in any Contract’s 1933 Act registration statement, any Contract Prospectus, sales literature or advertising covering the Contracts, or any amendment or supplement to any of the foregoing; or

(iv) arise as a result of any failure by SMFI to perform the obligations, provide the services and furnish the materials required of it under the terms of this Agreement, or any material breach of any representation and/or warranty made by SMFI in this Agreement or arise out of or result from any other material breach of this Agreement by SMFI.

(b) Except to the extent provided in Sections 12.2(c), 12.2(d) and 12.2(e) hereof, SMFI and AIC agree to indemnify and hold harmless the Indemnified Parties from and against any and all losses, claims, damages, liabilities (including amounts paid in settlement thereof with, the written consent of SMFI and/or AIC) or actions in respect thereof (including, to the extent reasonable, legal and other expenses) to which the Indemnified Parties may become subject directly or indirectly under any statute, at common law or otherwise, insofar as such losses, claims, damages, liabilities or actions directly or indirectly result from or arise out of the failure of any Fund to operate as a regulated investment company in compliance with (i) Subchapter M of the Code and regulations thereunder, or (ii) Section 817(h) of the Code and regulations thereunder, including the failure (whether intentional or otherwise) of each Fund to comply with the diversification requirements set forth in Section 817(h) of the Code and the regulations promulgated thereunder, and including further, without limitation, any income taxes and related penalties, rescission charges, liability under state law to Contractholders asserting

- 23 -

liability against LIFE COMPANY pursuant to the Contracts, the costs of any ruling and closing agreement or other settlement with the IRS, and the cost of any substitution by LIFE COMPANY of Shares of another investment company or portfolio for those of any adversely affected Fund as a funding medium for each Account that LIFE COMPANY reasonably deems necessary or appropriate as a result of the noncompliance.

(c) Neither SMFI nor AIC shall be liable under this Section 12.2 with respect to any losses, claims, damages, liabilities or actions to which an Indemnified Party would otherwise be subject by reason of willful misfeasance, bad faith, or gross negligence in the performance by that Indemnified Party of its duties or by reason of such Indemnified Party’s reckless disregard of its obligations and duties under this Agreement.

(d) Neither SMFI nor AIC shall be liable under this Section 12.2 with respect to any action against an Indemnified Party unless the Indemnified Party shall have notified SMFI and/or AIC in writing within a reasonable time after the summons or other first legal process giving information of the nature of the action 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 SMFI or AIC of any such action shall not relieve SMFI or AIC from any liability which it may have to the Indemnified Party against whom such action is brought otherwise than on account of this Section 12.2. Except as otherwise provided herein, in case any such action is brought against an Indemnified Party, SMFI and/or AIC will be entitled to participate, at its own expense, in the defense of such action and also shall be entitled to assume the defense thereof with counsel approved by the Indemnified Party named in the action, which approval shall not be unreasonably withheld or delayed. After notice from SMFI and/or AIC to such Indemnified Party of SMFI’s or AIC’s election to assume the defense thereof, the Indemnified Party will cooperate fully with SMFI and AIC and shall bear the fees and expenses of any additional counsel retained by it, and SMFI and AIC will not be liable to such Indemnified Party under this Agreement for any legal or other expenses subsequently incurred by such Indemnified Party independently in connection with the defense thereof, other than reasonable costs of investigation.

(e) In no event shall SMFI or AIC be liable under the indemnification provisions contained in this Agreement to any individual or entity, including, without limitation, LIFE COMPANY, UNDERWRITER, with respect to any losses, claims, damages, liabilities or expenses that arise out of or result from (i) a breach of any representation, warranty, and/or covenant made by LIFE COMPANY or UNDERWRITER hereunder; (ii) the failure by LIFE COMPANY or any Participating Insurance Company to maintain its segregated asset account (which invests in any Fund) as a legally and validly established segregated asset account under applicable state law and as a duly registered unit investment trust under the provisions of the 1940 Act (unless exempt therefrom); or (iii) the failure by LIFE COMPANY to maintain its variable annuity or life insurance contracts (with respect to which any Fund serves as an underlying funding vehicle) as annuity contracts or life insurance contracts under applicable provisions of the Code.

12.3 Effect of Notice.

- 24 -

Any notice given by the indemnifying Party to an Indemnified Party referred to in Sections 12.1 (c) or 12.2(d) above of participation in or control of any action by the indemnifying Party will in no event be deemed to be an admission by the indemnifying Party of liability, culpability or responsibility, and the indemnifying Party will remain free to contest liability with respect to the claim among the Parties or otherwise.

- 25 -

independently developed or compiled by SMFI from information supplied to it by the LIFE COMPANY Protected Parties’ customers who also maintain accounts directly with SMFI, SMFI will hold such information or property in confidence and refrain from using, disclosing or distributing any of such information or other property except: (a) with LIFE COMPANY’S prior written consent; or (b) as required by law or judicial process.

Section 19. Trademarks and Fund Names

(a) Summit Investment Partners, Inc. (“Summit” or “licensor”), an affiliate of SMFI, owns all right, title and interest in and to the name, trademark and service xxxx “Summit Pinnacle” and such other tradenames, trademarks and service marks as may be set forth on Schedule B, as amended from time to time by written notice from Summit to LIFE COMPANY (the “Summit licensed marks” or the “licensor’s licensed marks”) and is authorized to use and to license other persons to use such marks. LIFE COMPANY and its affiliates are hereby granted a non-exclusive license to use the Summit licensed marks in connection with LIFE COMPANY’s performance of the services contemplated under this Agreement, subject to the terms and conditions set forth in this Section 19.

(b) The grant of license to LIFE COMPANY and its affiliates ( the “licensee”) shall terminate automatically upon termination of this Agreement. Upon automatic termination, the licensee shall cease to use the licensor’s licensed marks, except that LIFE COMPANY shall have

- 26 -

the right to continue to service any outstanding Contracts bearing any of the Summit licensed marks. Upon Summit’s elective termination of this license, LIFE COMPANY and its affiliates shall immediately cease to issue any new annuity or life insurance contracts bearing any of the Summit licensed marks and shall likewise cease any activity which suggests that it has any right under any of the Summit licensed marks or that it has any association with Summit, except that LIFE COMPANY shall have the right to continue to service outstanding Contracts bearing any of the Summit licensed marks.

(c) The licensee shall obtain the prior written approval of the licensor for the public release by such licensee of any materials bearing the licensor’s licensed marks. The licensor’s approvals shall not be unreasonably withheld.

(d) During the term of this grant of license, a licensor may request that a licensee submit samples of any materials bearing any of the licensor’s licensed marks which were previously approved by the licensor but, due to changed circumstances, the licensor may wish to reconsider.

• Limitations on the ability to have exchanges effected other than by mail in the event of excessive or abusive transfers;

• Limitations on transfers into any investment option within 30 days of having transferred out of it (other than in connection with an automatic transfer program);

• Limitations on any transfers among sub-accounts within 30 days of prior transfer (other than in connection with an automatic transfer program); or

LIFE COMPANY also represents and warrants that the Contract prospectuses contain language describing its policies regarding excessive trading.

(b) SMFI will monitor daily trading activities of each Fund for excessive trading or potentially abusive exchanges, and will notify the LIFE COMPANY if it detects such trading or exchanges from LIFE COMPANY’S Accounts.
