NOW, THEREFORE, in consideration of their mutual promises, the Fund, the Adviser and the Company agree as follows:

ARTICLE I. Purchase and Redemption of Fund Shares

1.1. The Fund agrees to make available to the Company for purchase on behalf of the Accounts those shares of a Portfolio of the Fund which the Company orders on behalf of the Accounts, executing such orders on a daily basis at the net asset value next computed after receipt by the Fund or its designee of the order for such shares, as established in accordance with the provisions of the then current prospectus of the Fund.

1.2. The Fund will not sell shares of any Portfolio to any other Participating Insurance Company separate account unless an agreement containing provisions similar in substance to Sections 2.1 and 2.2 of Article II, Sections 3.7 and 3.8 (other than the provision requiring the Fund to provide voting standards) of Article III and Article V of this Agreement is in effect to govern such sales, it being agreed and understood by Company and the Fund that this provision is not intended to prevent the Fund from selling its shares to any potential investor whose purchase of shares does not render the shares of the Fund or any Portfolio ineligible for continued or additional investment by the Company and its Account(s), and it being further understood and agreed by the Company and the Fund that this provision shall apply prospectively to participation agreements that the Fund enters into on or after the date hereof.

1.3. The Company shall be the designee of the Fund for receipt of purchase orders and requests for redemptions or exchanges of shares of a Portfolio (“Instructions”). The Business Day on which such Instructions are received in proper form by the Company and time

stamped by the Company by the close of trading of the New York Stock Exchange will be the date and time as of which Portfolio shares shall be deemed purchased, exchanged or redeemed as a result of such Instructions; provided that the Fund receives such Instructions by 9:30 a.m. Eastern Time on the next following business day. Instructions received in proper form by the Company and time stamped after the close of trading of the New York Stock Exchange on any given Business Day or received by the Fund after 9:30 a.m. Eastern Time on the next following business day shall be treated as if received on the next following Business Day. The Company warrants that all orders transmitted to the Fund by 9:30 a.m. Eastern Time on a Business Day were received by the Company in proper form and time stamped prior to the close of trading of the New York Stock Exchange 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 and its current prospectus.

The Fund shall calculate the net asset value per share of each Portfolio on each Business Day, and shall communicate these net asset values to the Company or its designee on a daily basis as soon as reasonably practicable after the calculation is completed (normally by 6:30 p.m. Eastern time). If the Fund is unable to meet the 6:30 p.m. time stated herein, the Fund shall provide additional time equal to the additional time it takes the Fund to make the net asset value available to the Company for the Company to place orders for the purchase and redemption of shares and make any applicable purchase payments.

The Company shall submit payment for the purchase of shares of a Portfolio in federal funds transmitted by wire to the Fund or to its designated custodian, which must receive such wires no later than the close of the Federal Reserve Bank of New York, which is 6:00 p.m.

Eastern time, on the Business Day following the Business Day on which such purchase orders were received by the Company.

Issuance and transfer of the Portfolio shares will be by book entry only. Stock certificates will not be issued to the Company or the Accounts. Portfolio shares purchased from the Fund will be recorded in the name of the appropriate Account or the appropriate subaccount of each Account.

The Fund shall furnish, on or before the ex-dividend date, notice to the Company of any income dividends or capital gain distributions payable on the shares of any Portfolio. The Company hereby elects to receive all such income dividends and capital gain distributions as are payable on shares of a Portfolio in additional shares of that Portfolio, and the Company reserves the right to change this election in the future. The Fund will notify the Company of the number of shares so issued as payment of such dividends and distributions.

Each party to this Agreement agrees that, in the event of a material error resulting from incorrect information or confirmations, the parties will seek to comply in all material respects with the provisions of applicable federal securities laws.

1.4. The Fund agrees to make Portfolio shares available for purchase by the Company for their separate Accounts listed in Schedule 1 on those days on which a Portfolio calculates its net asset value pursuant to rules of the SEC; provided, however, that the Board of Trustees of the Fund (hereinafter 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, in the best interests of the shareholders of any Portfolio (including without limitation purchase orders that individually or together with other contemporaneous orders represent large transactions in shares of any Portfolio, held for a relatively brief period of time). Such shares shall be purchased at the applicable net asset value per share, increased by any initial sales charge, if the Fund’s prospectus then in effect imposes such a charge on such purchases. It is not anticipated that the classes of shares that will be purchased by the Company on behalf of its Accounts will incur sales charges. Without limiting the foregoing, the Fund and the Fund’s transfer agent may take such other action (including, without limitation, rejecting specific purchase orders) as they deem necessary to reduce, discourage or eliminate frequent trading activity that the Fund or the Fund’s transfer agent, in their discretion, believe would be disruptive, after first investigating the matter with advance notice to, and the assistance of, the Company in identifying frequent trading, and after having provided the Company with reasonable opportunity to take action to eliminate or curb such activities by Contract owners who have been identified as participating in such trading. The Company has provided the Fund with a written description of its frequent trading policy and procedures and agrees to follow the Fund’s frequent trading policy and procedures as disclosed in the applicable Portfolio’s prospectus and the Fund’s Statement of Additional Information, as amended and supplemented from time to time, and to cooperate with the Fund and the Adviser to assist in the implementation of the Fund’s restrictions (in accordance with the terms hereof) on purchase, redemption and exchange activity on the part of Contract owners in the Accounts that the Fund or the Fund’s transfer agent, in their discretion, believe would be disruptive, including but not limited to providing information on Fund related Contract owner transactions, holdings and other information as may reasonably be requested by the Fund, the Adviser or their duly authorized

representatives. The Company shall provide copies of any significant amendments to its policies and procedures on frequent trading to the Fund.

1.5. The Fund agrees to redeem or exchange, upon the Company’s request, any full or fractional shares of the Fund held by the Company, executing such requests on a daily basis at the net asset value next computed after receipt by the Fund or its designee of the request for redemption, reduced by any redemption fee or deferred sales charge (neither of which apply to the class of shares purchased by the Company as of the effective date of this Agreement), if the Fund’s prospectus in effect as of the date of such redemption imposes such a fee or charge on such redemptions. For purposes of this Section 1.4, the Company shall be the designee of the Fund for receipt of requests for redemption and receipt by such designee shall constitute receipt by the Fund; provided that the Fund receives written (or facsimile) notice of such request for redemption by 9:30 a.m. Eastern Time on the next following Business Day; however the Company undertakes to use its best efforts to provide such notice to the Fund by no later than 9:00 A.M. Eastern time on the next following Business Day. Payment shall be made within the time period specified in the Fund’s prospectus or statement of additional information (“SAI”), provided, however, that in no event shall payment be delayed for a greater period than is permitted by the 1940 Act. In the event the Fund does not pay for the Fund shares that are redeemed on the next Business Day after a request to redeem shares is made, then the Fund shall apply any such delay in redemptions uniformly and pro rata to all record holders of shares of that Portfolio on the day the request is made. Payment shall be in federal funds transmitted by wire to the Company’s bank accounts as designated by the Company in writing from time to time. The Company further agrees to furnish, or cause to be furnished, to the extent permitted by its independent public accounting firm, to the Fund, the Adviser and their duly appointed agents a

copy of the Company’s SAS 70 report, in so far as its relates to procedures and controls involving the Fund, prepared by the Company’s independent auditor within a reasonable time such report is completed and to submit to an inspection by the Fund, the Adviser or their duly authorized agents of its books and records, in so far as they pertain to the Fund, upon reasonable notice.

1.6. The Company agrees to purchase and redeem the shares of the Portfolios named in Schedule 2 offered by the then current prospectus and SAI of the Fund in accordance with the provisions of such prospectus and SAI. The Company shall not permit any person other than a Contract owner or policyholder, or their duly appointed representatives and designees, to give instructions to the Company which would require the Company to purchase, redeem or exchange shares of the Fund.

1.7 The Fund offers share classes which impose redemption fees in certain circumstances (“Redemption Fee Funds”) and, with respect to such Redemption Fee Funds, the Company agrees to monitor holding periods of Contract owners and to track such holding periods for purposes of the Fund’s assessment of redemption fees in conjunction with those transactions specifically subject to such fees, subject to any reasonable exceptions as set forth in the Redemption Fee Funds prospectuses. The Company shall maintain records supporting its calculations of redemption fees payable to each Fund and shall provide the Fund with access, to or copies of, such records upon the reasonable request of the Fund. Company shall calculate the amount of redemption fees payable to each Fund on a daily basis and such amount shall be netted against the redemption proceeds payable by the Company.

Nothing herein shall be construed to require actions on the part of Company that would, in the best judgment of the Company, constitute the violation or breach of any duty the

Company owes to Contract owners whose Contracts were purchased prior to the creation of the Redemption Fee Fund shares. The Company is not purchasing such Redemption Fee Funds as of the effective date of this Agreement and will not do so unless the Fund is notified otherwise in writing, signed by a duly authorized officer of the Company.

ARTICLE II. Representations and Warranties

2.1. The Company represents and warrants that the securities deemed to be issued by the Accounts under the Contracts are or, prior to any issuance or sale will be, registered under the 1933 Act (unless an exemption from registration is available) and, that the Contracts will be issued, offered and sold in compliance in all material respects with all applicable federal and state laws and regulations, including without limitation state insurance suitability requirements and National Association of Securities Dealers, Inc. (“NASD”) conduct rules. The Company further represents and warrants that it is an insurance company duly organized and in good standing under applicable state law and that it has legally and validly established the Accounts prior to the issuance or sale of units thereof as a segregated asset account under applicable insurance law and has registered the Accounts as unit investment trusts in accordance with the provisions of the 1940 Act (unless an exclusion from registration is available) to serve as segregated investment accounts for the Contracts, and that it will maintain such registration for so long as any Contracts are outstanding or until registration is no longer required under federal and state securities laws. The Company shall amend the registration statement under the 1933 Act for the Contracts and the registration statement under the 1940 Act for the Accounts from time to time as required in order to effect the continuous offering of the

Contracts or as may otherwise be required by applicable law. The Company shall register and qualify the Contracts for sale in accordance with the securities laws of the various states only if and to the extent deemed necessary by the Company.

2.2. The Company represents and warrants that the Contracts are currently and at the time of issuance will be treated as life insurance or annuity contracts under applicable provisions of the Internal Revenue Code of 1986, as amended (the “Code”) and the regulations issued thereunder, and that it will make every effort to maintain such treatment and that it will notify the Fund and the Adviser immediately upon having a reasonable basis for believing that the Contracts have ceased to be so treated or that they might not be so treated in the future. In addition, the Company represents and warrants that the Accounts are “segregated asset accounts” and that interests in the Accounts 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 issued thereunder and any amendments or other modifications to such section or such regulations (and any revenue rulings, revenue procedures, notices and other published announcements of the Internal Revenue Service interpreting these provisions). The Company shall continue to meet such definitional requirements, and it will notify the Fund and the Adviser 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. The Company represents and warrants that it will not purchase Fund shares with assets derived from tax-qualified retirement plans except indirectly, through Contracts purchased in connection with such plans.

2.3. The Fund represents and warrants that Fund shares sold pursuant to this Agreement shall be registered under the 1933 Act and duly authorized for issuance and sold in accordance with applicable state and federal law and that the Fund is and shall remain registered

under the 1940 Act for as long as the Fund shares are sold. The Fund shall amend the registration statement for its shares 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 Fund shall register and qualify the shares for sale in accordance with the laws of the various states only if and to the extent deemed advisable by the Fund.

2.4. The Fund will at all times invest money from the Contracts in such a manner as to ensure that the Contracts will be treated as variable contracts under the Code and the regulations issued thereunder. Without limiting the scope of the foregoing, the Fund represents and warrants that each Portfolio of the Fund will comply with Section 817(h) of the Code and Treasury Regulation 1.817-5, relating to the diversification requirements for variable annuity, endowment, or life insurance contracts and any amendments or other modifications to such Section or Regulations (and any revenue rulings, revenue procedures, notices, and other published announcements of the Internal Revenue Service interpreting these provisions). In the event the Fund should fail to so qualify, it will take all reasonable steps (a) to notify the Company of such breach and (b) to resume compliance with such diversification requirement within the grace period afforded by Treasury Regulation 1.817.5. The Fund and Adviser represent that each Portfolio is qualified as a Regulated Investment Company under Subchapter M of the Code and that it will maintain such qualification (under Subchapter M or any successor provision), and that it will notify the Company immediately upon having a reasonable basis for believing that it has ceased to so qualify or that it might not so qualify in the future.

2.5. If the Contracts purchase shares of a series and class of the Fund that have adopted a plan under Rule 12b-1 under the 1940 Act to finance distribution expenses (a “12b-1

Plan”), the Company agrees to provide the Trustees any information as may be reasonably necessary for the Trustees to review the Fund’s 12b-1 Plan or Plans.

2.8. The Fund and Adviser each represent and warrant that all of its respective directors, trustees, officers, employees, investment advisers, and transfer agent of the Fund are and shall continue to be at all times covered by a blanket fidelity bond (which may, at the Fund’s election, be in the form of a joint insured bond) or similar coverage for the benefit of the Fund in an amount not less than the minimal coverage as required currently by Section 17(g) and Rule 17g-1 under the 1940 Act or related provisions as may be promulgated from time to time. The aforesaid Bond shall include coverage for larceny and embezzlement and shall be issued by a reputable insurance company. The Adviser agrees to make all reasonable efforts to see that this bond or another bond containing these provisions is always in effect, and agrees to notify the Company in the event that such coverage no longer applies.

2.9. The Company represents and warrants that all of its directors, officers, employees, agents, investment advisers, and other individuals and entities dealing with the money and/or securities of the Fund are covered by a blanket fidelity bond or similar coverage in an amount not less than the equivalent of U.S. $10 million. The aforesaid bond shall include coverage for larceny and embezzlement and shall be issued by a reputable insurance company.

The Company agrees that any amount received under such bond in connection with claims that derive from arrangements described in this Agreement will be paid by the Company for the benefit of the Fund. The Company agrees to make all reasonable efforts to see that this bond or another bond containing these provisions is always in effect, and agrees to notify the Fund and the Adviser in the event that such coverage no longer applies.

2.10. The Fund and the Adviser represent that they will make a good faith effort to furnish information to the Company about the Fund not otherwise available to the Company which is required by state insurance law to enable the Company to obtain the authority needed to issue the Contracts in any applicable state.

The Company undertakes and agrees to comply, and to take full responsibility in complying with any and all laws, regulations, protocols and other requirements relating to money laundering, both United States and foreign, including, without limitation, the International Money Laundering Abatement and Anti-Terrorist Financing Act of 2001 (Title III of the USA Patriot Act), hereinafter, collectively with the rules, regulations and orders promulgated thereunder (the “Patriot Act”) and any requirements and/or requests in connection therewith, made by regulatory authorities, the Fund or their duly appointed agents, either generally or in respect of a specific transaction, and/or in the context of a “primary money laundering concern” as defined in the Patriot Act. The Company agrees as a condition precedent to any transaction taking or continuing to be in effect under this Agreement, to comply with any and all anti-money laundering laws, regulations, orders or requirements, and without prejudice to the generality of the above, to provide regulatory authorities, the Fund or its duly appointed agents, with all necessary reports and information for the Fund or its agents to fulfill their obligations, if any, under the Patriot Act for the purposes of the Fund or other third parties complying with any and

all anti-money laundering requirements imposed by the Patriot Act, including, without limitation, enhanced due diligence obligations, the filing of Currency Transaction Reports and/or of Suspicious Activity Reports obligations, and/or the sharing of information requirements. In the event reports and information reasonably deemed satisfactory by the Fund are not received within a reasonable time period from the date of the request, the Fund reserve the right, to reject any transaction and/or cease to transact with the Company and/or the Accounts.

Further, the Company represents that the Company has not received notice of, and to the Company’s knowledge, there is no basis for, any claim, action, suit, investigation or proceeding that might result in a finding that the Company is not or has not been in compliance with the Patriot Act, and the rules and regulations promulgated thereunder.

2.11. The Company, the Fund and the Advisor each agree to notify the others immediately upon having a reasonable basis for believing that any of these representations and warranties are no longer true or accurate to a material extent.

2.12 The Company shall maintain and enforce policies and procedures reasonably designed to ensure that Portfolio share orders transmitted to the Fund are segregated by time of receipt in order to prevent Share orders from being executed at a price based on a previously determined net asset value.

2.13 The Company shall facilitate and cooperate with third-party audits arranged by the Fund or the Adviser to evaluate the effectiveness of its compliance controls.

No such material shall be used if the Fund or its designee reasonably object to such use within ten Business Days after receipt of such material.

3.2. The Company shall not give any information or make any representations or statements on behalf of the Fund or concerning the Fund in connection with the sale of the Contracts other than the information or representations contained in the registration statement or prospectus for the Fund shares, as such registration statement and prospectus may be amended or supplemented from time to time, or in reports or proxy statements for the Fund, or in sales literature or other promotional material approved by the Fund or its designee, except with the permission of the Fund.

3.3. For purposes of this Article III, the phrase “sales literature or other promotional material” includes, but is not limited to, portions of the following that use any logo or other trademark related to the Fund or its affiliates, and any of the following that refer to the Fund or an affiliate of the Fund: advertisements (such as material published, or designed for use in, a newspaper, magazine, or other periodical, radio, television, telephone or tape recording, videotape display, signs or billboard or electronic media), and sales literature (i.e., any written communication distributed or made generally available to customers or the public, including brochures, circulars, market letters and form letters, seminar texts, reprints or excerpts from any advertisement, sales literature or published article), educational training materials or other communications distributed or made generally available to some or all agents or employees, and registration statements, prospectuses, SAIs, shareholder reports, and any other communications distributed or made generally available with regard to the Fund.

The Fund shall provide to the Company a copy of its current prospectus within a reasonable period of its filing date, and provide other assistance as is reasonably necessary in order for the Company once each year (or more frequently if the prospectus for the Fund is supplemented or amended) to have the prospectus for the Contracts and the Fund’s prospectus printed together in one document. The Adviser shall be permitted to review and approve the typeset form of the Fund’s Prospectus prior to such printing. If the Company elects to include a copy of the Fund’s prospectus printed together with the prospectus for the Contracts as one document, the Fund shall promptly upon request provide by e-mail and/or disk, print-ready WORD, .pdf or other electronic files customarily used in the financial printing industry.

within a reasonable period of the filing date for definitive copies of such material. The Adviser shall be permitted to review and approve the typeset form of such proxy material, shareholder reports and communications prior to such printing.

(iii) vote Fund shares for which no instructions have been received in the same proportion as Fund shares of such Portfolio(s) for which instructions have been received,

The Company will vote Fund shares held in any segregated asset account, as well as shares owned by the Company, in the same proportion as Fund shares of such Portfolio for which voting instructions have been received from Contract owners, to the extent permitted by law.

3.8 Participating Insurance Companies shall be responsible for assuring that each of their separate accounts participating in a Portfolio calculates voting privileges as required by the Mixed and Shared Funding Exemptive Order and consistent with any reasonable standards that the Fund may adopt and provide in writing.

4.2. All expenses incident to performance by each party of its respective duties under this Agreement shall be paid by that party.

Unless otherwise agreed, the Company shall bear the expenses of printing copies of the current prospectus and profiles for the Contracts; printing copies of the Fund’s prospectus and profiles that are used in connection with offering the Contracts; distributing the Fund’s prospectus to owners of Contracts issued by the Company; and of distributing the Fund’s proxy materials and reports to such Contract owners. If the prospectus for the Contracts and the

Fund’s prospectus are printed together in one or more documents, printing costs shall be allocated to reflect the Fund’s share, pursuant to Section 4.3, of the total costs for printing the Fund’s prospectus(es) to be delivered to existing Contract owners investing in the Portfolio(s), determined according to the number of pages of the Fund’s respective portions of the documents.

4.5. In the event the Fund adds one or more additional Portfolios and the parties desire to make such Portfolios available to the respective Contract owners as an underlying investment medium, a new Schedule 2 or an amendment to this Agreement shall be executed by the parties authorizing the issuance of shares of the new Portfolios to the particular Accounts. The amendment may also provide for the sharing of expenses for the establishment of new Portfolios among Participating Insurance Companies desiring to invest in such Portfolios and the provision of funds as the initial investment in the new Portfolios.

ARTICLE V. Potential Conflicts

5.1. The Trustees will monitor the Fund for the existence of any material irreconcilable conflict between the interests of the Contract owners of all separate accounts investing in the Fund. 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 participating insurance companies or 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 Trustees shall promptly inform the Company if it determines that an irreconcilable material conflict exists and the implications thereof.

5.2. The Company has reviewed a copy of the Mixed and Shared Funding Exemptive Order, and in particular, has reviewed the conditions to the requested relief set forth therein. The Company agrees to be bound by the responsibilities of a participating insurance company as set forth in the Mixed and Shared Funding Exemptive Order, including without limitation the requirement that the Company 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 in monitoring such conflicts under the Mixed and Shared Funding Exemptive Order, by providing the Trustees in a timely manner with all information reasonably necessary for the Trustees to consider any issues raised. This includes, but is not limited to, an obligation by the Company to inform the Trustees whenever Contract owner voting instructions are disregarded and by confirming in writing, at the Fund’s request, that the Company are unaware of any such potential or existing material irreconcilable conflicts.

5.3. If it is determined by a majority of the Trustees, or a majority of its disinterested Trustees, that a material irreconcilable conflict exists, the Company shall, at its expense and to the extent reasonably practicable (as determined by a majority of the disinterested Trustees), take whatever steps are necessary to remedy or eliminate the irreconcilable material conflict, up to and including: (1) withdrawing the assets allocable to some or all of the separate accounts from 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 whether such segregation should be implemented to a vote of all affected Contract owners and, as appropriate, segregating the assets of any appropriate group (i.e., annuity contract owners, life insurance contract owners, or variable contract owners of one or more 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 (2) establishing a new registered management investment company or managed separate accounts. The Company’s obligations under this Section 5.3 shall not depend on whether other affected participating insurance companies fulfill a similar obligation.

5.4. If a material irreconcilable conflict arises because of a decision by the Company to disregard Contract owner voting instructions and that decision could conflict with the majority of Contract owner instructions, the Company may be required, at the Fund’s election, to withdraw the Accounts’ investment in the Fund and terminate this Agreement; 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 Fund gives written notice that this provision is being implemented, and until the end of the six month period the Fund shall continue to accept and implement orders by the Company for the purchase and redemption of shares of the Fund.

5.5. 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 Accounts’ investment in the Fund and terminate this Agreement within six 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 the foregoing six month period, the Fund shall continue to accept and

implement orders by the Company for the purchase and redemption of shares of the Fund, subject to applicable regulatory limitation.

5.6. For purposes of Sections 5.3 through 5.6 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 Fund be required to establish a new funding medium for the Contracts. The Company shall not be required by Section 5.3 to establish a new funding medium for 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 particular Accounts’ investment in the Fund 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.

(g) at the option of the Company or the Fund upon a determination by a majority of the Trustees, or a majority of the disinterested Trustees, that an irreconcilable material conflict exists among the interests of (i) all Contract owners of variable insurance products of all separate accounts or (ii) the interests of the Participating Insurance Companies investing in the Fund as delineated in Article VII of this Agreement;

(h) at the option of the Company if the Fund ceases to qualify as a Regulated Investment Company under Subchapter M of the Code, or under any successor or similar provision, or if the Company reasonably believes that the Fund may fail to so qualify;

(i) at the option of the Company if the Fund fails to meet the diversification requirements specified in Section 2.6 hereof or if the Company reasonably believes that the Fund will fail to meet such requirements;

(j) at the option of any party to this Agreement, upon another party’s failure to cure a material breach of any provision of this Agreement within thirty days after written notice thereof;

7.2. It is understood and agreed that the right of any party hereto to terminate this Agreement pursuant to Section 7.1(a) may be exercised for cause or for no cause.

(vi) arise out of or result from a Contract failing to be considered a life insurance policy or an annuity Contract, whichever is appropriate, under applicable provisions of the Code thereby depriving the Fund of its compliance with Section 817(h) of the Code, unless such failure is due to the failure of the Fund or any of the other investment companies currently available as funding vehicles for the Contracts to invest the assets of any portfolio in such a manner as to ensure that the Contracts will be treated as annuity, endowment, or life insurance contracts, whichever is appropriate, under the Code and the regulations issued thereunder (or any successor provisions).

8.3. Indemnification Procedure

Any person obligated to provide indemnification under this Article VIII (“indemnifying party” for the purpose of this Section 8.3) shall not be liable under the indemnification provisions of this Article VIII with respect to any claim made against a party entitled to indemnification under this Article VIII (“indemnified party” for the purpose of this Section 8.3) unless such indemnified party shall have notified the indemnifying party in writing within a reasonable time after the summons or other first legal process giving information of the nature of the claim shall have been served upon such indemnified party (or after such party shall have received notice of such service on any designated agent), but failure to notify the indemnifying party of any such claim shall not relieve the indemnifying party from any liability which it may have to the indemnified party against whom such action is brought under the indemnification provisions of this Article VIII, except to the extent that the failure to notify results in the failure of actual notice to the indemnifying party and such indemnifying party is damaged solely as a result of failure to give such notice. In case any such action is brought against the indemnified party, the indemnifying party will be entitled to participate, at its own expense, in the defense thereof. The indemnifying party also shall be entitled to assume the defense thereof, with counsel satisfactory to the party named in the action. After notice from the indemnifying party to the indemnified party of the indemnifying party’s election to assume the defense thereof, the indemnified party shall bear the fees and expenses of any additional counsel retained by it, and the indemnifying party will not be liable to such party under this Agreement

for any legal or other expenses subsequently incurred by such party independently in connection with the defense thereof other than reasonable costs of investigation, unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment.

A successor by law of the parties to this Agreement shall be entitled to the benefits of the indemnification contained in this Article VIII. The indemnification provisions contained in this Article VIII shall survive any termination of this Agreement.

ARTICLE IX. Notices

Any notice shall be sufficiently given when sent by registered or certified mail, by facsimile transmission with a confirmation of receipt, or by recognized overnight courier or delivery service, to the other party at the address or fax number of such party set forth below or at such other address as such party may from time to time specify to the other party.
