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

ARTICLE I
Sale of Fund Shares

1.1 The Underwriter agrees to sell to the Company those shares of the Designated Portfolios that the Accounts order, 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 the shares of the Designated Portfolios.

1.2 The Fund agrees to make shares of each Designated Portfolio available for purchase at the applicable net asset value per share by the Company on behalf of the Accounts on those days on which the Fund calculates such Designated Portfolio’s net asset value pursuant to rules of the SEC, and the Fund shall use reasonable efforts to calculate such net asset value on the days and

at the times described in the Fund’s prospectus (as of the close of the New York Stock Exchange on each day when the New York Stock Exchange is open for trading). Notwithstanding the foregoing, the Board of Trustees of the Fund (“Board”) may refuse to sell shares of any Designated Portfolio to any person, or suspend or terminate the offering of shares of any Designated Portfolio if such action is required by law or by regulatory authorities having jurisdiction, or is, in the sole discretion of the Board acting in good faith and in light of its fiduciary duties under federal and any applicable state laws, necessary in the best interest of the shareholders of such Designated Portfolio.

1.3 The Fund and the Underwriter agree that shares of the Fund will be sold only to Participating Insurance Companies or their separate accounts, or to certain Retirement Plans. No shares of any Designated Portfolios will be sold to the general public. However, it is understood by the Company that the Fund may sell shares of any Designated Portfolio to any person eligible to invest in that Designated Portfolio in accordance with applicable provisions of Section 817(h) under the Internal Revenue Code of 1986, as amended (“Code”) and the regulations thereunder, and that if such provisions are not applicable, then the Fund may sell shares of any Designated Portfolio to any person, including members of the general public. The Fund and the Underwriter will not sell shares of any Designated Portfolio to any insurance company or separate account unless an agreement containing provisions substantially the same as Sections 2.1, 3.4, 3.5 and 3.6 and Article VII of this Agreement is in effect to govern such sales.

1.4 The Fund agrees to redeem, on the Company’s request, any full or fractional shares of the Designated Portfolios 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, and receipt of requests for redemption by such designee by 4:00 p.m. New York time (the “Valuation Time”) shall constitute receipt by the Fund, except that the Fund reserves the right to suspend the right of redemption or postpone the date of payment or satisfaction upon redemption consistent with Section 22(e) of the 1940 Act and any rules or order thereunder, and in accordance with the procedures and policies of the Fund as described in the Fund’s then current prospectus.

1.5 For purposes of Sections 1.1 and 1.4, the Company shall be the designee of the Fund solely for receipt of purchase and redemption orders from the Accounts, and receipt by such designee shall constitute receipt by the Fund; provided that the Company receives the order prior to the Valuation Time on a Business Day and the Fund receives notice of such order by 9:30 a.m. New York time on the next following Business Day. “Business Day” shall mean any day on which the New York Stock Exchange is open for trading and on which the Fund calculates its net asset value pursuant to the rules of the SEC.

1.6 The Company agrees to purchase and redeem the shares of each Designated Portfolio offered by the Fund’s then current prospectus in accordance with the provisions of such prospectus. The Company shall use its best efforts, and shall reasonably cooperate with, the Fund to enforce stated prospectus policies regarding transactions in Designated Portfolio shares. The Company acknowledges that orders accepted by it in violation of the Fund’s stated policies may be subsequently revoked or cancelled by the Fund and that the Fund shall not be responsible for any losses incurred by the Company or the Contract owner as a result of such cancellation. In addition, the Company acknowledges that the Fund has the right to refuse any purchase order

for any reason, particularly if the Fund determines that a Designated Portfolio would be unable to invest the money effectively in accordance with its investment policies or would otherwise be adversely affected due to the size of the transaction, frequency of trading, or other factors.

1.7 In the event of net purchases, the Company shall pay for shares of a Designated Portfolio on the next Business Day after receipt of an order to purchase shares of such Designated Portfolio. Payment shall be in federal funds transmitted by wire by 11:00 a.m. New York time. If payment in federal funds for any purchase is not received or is received by the Fund after 11:00 a.m. New York time on such Business Day, the Company shall promptly, upon the Fund’s request, reimburse the Fund for any charges, costs, fees, interest or other expenses incurred by the Fund in connection with any advances to, or borrowing or overdrafts by, the Fund, or any similar expenses incurred by the Fund, as a result of portfolio transactions effected by the Fund based upon such purchase request. For purposes of Section 2.8 and 2.9 hereof, upon receipt by the Fund of the federal funds so wired, such funds shall cease to be the responsibility of the Company and shall become the responsibility of the Fund.

1.7A In the event of net redemptions, the Fund shall pay the redemption proceeds in federal funds transmitted by wire on the next Business Day after an order to redeem a Designated Portfolio’s shares is made in accordance with the provision of Section 1.4 hereof. Notwithstanding the foregoing, if the payment of redemption proceeds on the next Business Day would require the Designated Portfolio to dispose of securities or otherwise incur substantial additional costs and if the Fund had determined to settle redemption transactions for all shareholder of the Designated Portfolio on a delayed basis, proceeds shall be wired to the Company within seven (7) days and the Designated Portfolio shall notify in writing the person designated by the Company as the recipient for such notice of such delay by 3:00 p.m. New York time on the same Business Day that the Company transmits the redemption order to the Fund. For purposes of Section 2.8 and 2.9 hereof, upon receipt by the Company of the federal funds so wired, such funds shall cease to be the responsibility of the Fund and shall become the responsibility of the Company.

1.8 Unless otherwise determined by the Board, issuance and transfer of the shares of a Designated Portfolio will be by book entry only. Stock certificates will not be issued to the Company or any Account. Shares of a Designated Portfolio ordered from the Fund will be recorded in an appropriate title for each Account or the appropriate subaccount of each Account.

1.9 The Fund shall furnish same-day notice by 6:00 p.m. New York time by wire or telephone, followed by written confirmation, to the Company of any income, dividends or capital gain distributions payable on shares of the Designated Portfolios. The Company hereby elects to receive all such income, dividends, and capital gain distributions as are payable on shares of a Designated Portfolio in additional shares of that Designated Portfolio. The Fund shall notify the Company of the number of shares so issued as payment of such dividends and distributions. The Company reserves the right to revoke this election and to receive all such dividends and capital gain distributions in cash. The Fund shall use its best efforts to furnish advance notice of the day such dividends and distributions are expected to be paid.

1.10 The Fund shall use its best efforts to make the net asset value per share for each Designated Portfolio available to the Company on a daily basis as soon as reasonably practical

after the net asset value per share is calculated (normally by 6:30 p.m. New York time) and shall use its best efforts to make such net asset value per share available by 7:00 p.m. New York time. The Fund will provide NAV per share by modem with fax follow-up. Neither the Adviser nor the Fund shall be liable for any information provided to the Company pursuant to this Agreement, which information is based on incorrect information supplied by the Company or any other Participating Insurance Company.

1.11 If the Fund provides materially incorrect share net asset value information through no fault of the Company, the Company shall be entitled to an adjustment with respect to the Fund shares purchased or redeemed to reflect the correct net asset value per share. The determination of the materiality of any net asset value pricing error shall be based on the SEC’s recommended guidelines, if any. The correction of any such errors shall be made at the Company level and shall be made pursuant to the SEC’s recommended guidelines. 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 the Company. Upon notification by the Adviser of any overpayment due to a material error, the Company shall promptly remit to the Adviser any overpayment that has not been paid to Contract owners.

1.12 The Fund shall provide statements of account no less frequently than monthly (and if possible, shall provide the same daily or weekly on a rolling monthly basis) by the 15^thday of the following month.

1.13 (a) The Company may withdraw the Account’s investment in the Fund or a Portfolio of the Fund only: (i) as necessary to facilitate Contract Owner requests; (ii) as provided in Article VII; or (iii) in the event that the shares of another investment company are substituted for Portfolio shares in accordance with the terms of the Contracts upon the (x) requisite vote of the contract owners having an interest in the affected Portfolios and the written consent of the Fund (unless otherwise required by applicable law); (y) upon issuance of an SEC exemptive order pursuant to Section 26(c) of the 1940 Act permitting such substitution; or (z) as may otherwise be permitted under applicable law.

(b) The Company shall not, without the prior written consent of the Fund or upon 90 days’ written notice (unless otherwise required by applicable law), take any action to operate the Account as a management investment company under the 1940 Act.

(c) The Fund shall not, without the prior written consent of the Company or upon 90 days’ written notice (unless otherwise required by applicable law), take any action to operate the Fund as a unit investment trust under the 1940 Act.

(d) The Company shall not, without the prior written consent of the Fund (unless otherwise required by applicable law), solicit, induce or encourage Contract owners to change or modify the Fund or change the Fund’s investment adviser.

1.14 The Parties hereto acknowledge that the arrangement contemplated by this Agreement is not exclusive; the shares of the Designated Portfolios (and other Portfolios of the Fund) may be sold to other insurance companies (subject to Section 1.3 and Article VII hereof) and Retirement Plans and the cash value of the Contracts may be invested in other investment companies.

6.2 The Fund represents that each Designated Portfolio is currently qualified (and for new Designated Portfolios, intends to qualify) as a Regulated Investment Company under Subchapter M of the Code, and that it will make every effort to maintain such qualification (under Subchapter M or any successor or similar provisions) and that it will notify the Company

immediately upon having a reasonable basis for believing that a Designated Portfolio has ceased to so qualify or that a Designated Portfolio might not so qualify in the future.

6.3 The Company represents that the Contracts are currently, and at the time of issuance shall be, treated as life insurance or annuity insurance contracts, under applicable provisions of the Code, and that it will make every effort to maintain such treatment, and that it will notify the Fund, the Adviser and the Underwriter immediately upon having a reasonable basis for believing the Contracts have ceased to be so treated or that they might not be so treated in the future. The Company agrees that any prospectus offering a contract that is a “modified endowment contract” as that term is defined in Section 7702A of the Code (or any successor or similar provision), shall identify such contract as a modified endowment contract. In addition, 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 every effort to continue to meet such definitional requirements, and it will notify the Fund, the Underwriter 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.

6.4 The Company agrees that if the Internal Revenue Service (“IRS”) asserts in writing in connection with any governmental audit or review of the Company (or, to the Company’s knowledge, of any Contract owner) that any Designated Portfolio has failed to comply with the diversification requirements of Section 817(h) of the Code or the Company otherwise becomes aware of any facts that could give rise to any claim against the Fund, Underwriter or Adviser as a result of such a failure or alleged failure:

(a) The Company shall promptly notify the Fund, the Underwriter and the Adviser of such assertion or potential claim;

(b) The Company shall consult with the Fund, the Underwriter and the Adviser as to how to minimize any liability that may arise as a result of such failure or alleged failure;

(c) The Company shall use its best efforts to minimize any liability of the Fund, the Underwriter and the Adviser resulting from such failure, including, without limitation, demonstrating, pursuant to Treasury Regulations, Section 1.817-5(a)(2), to the commissioner of the IRS that such failure was inadvertent;

(d) Any written materials to be submitted by the Company to the IRS, any Contract owner or any other claimant in connection with any of the foregoing proceedings or contests (including, without limitation, any such materials to be submitted to the IRS pursuant to Treasury Regulations, Section 1.817-5(a)(2)) shall be provided by the Company to the Fund, the Underwriter and the Adviser (together with any supporting information or analysis) within at least two (2) business days prior to submission;

(e) The Company shall cooperate, to the extent reasonable, with the Fund, the Underwriter and the Adviser in order to facilitate review by the Fund, the Underwriter and the Adviser of any written submissions provided to it or its assessment of the validity or amount of any claim against it arising from such failure or alleged failure;

(f) The Company shall not with respect to any claim of the IRS or any Contract owner that would give rise to a claim against the Fund, the Underwriter and the Adviser (i) compromise or settle any claim, (ii) accept any adjustment on audit, or (iii) forego any allowable administrative or judicial appeals, without the express written consent of the Fund, the Underwriter and the Adviser, which shall not be unreasonably withheld; provided that, the Company shall not be required to appeal any adverse judicial decision unless the Fund and the Adviser shall have provided an opinion of independent counsel to the effect that a reasonable basis exists for taking such appeal; and further provided that the Fund, the Underwriter and the Adviser shall bear the costs and expenses, including reasonable attorney’s fees, incurred by the Company in complying with this clause (f).

ARTICLE VII
Potential Conflicts

7.1 The Board 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 but not limited to: (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 Designated 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 Board shall promptly inform the Company if it determines that an irreconcilable material conflict exists and the implications thereof.

7.2 The Company and the Adviser will report any potential or existing conflicts of which each is aware to the Board. The Company will assist the Board in carrying out its responsibilities under the Shared Funding Exemption Order, by providing the Board with all information reasonably necessary for the Board to consider any issues raised. This includes, but is not limited to, an obligation by the Company to inform the Board whenever Contract owner voting instructions are disregarded. At least annually, and more frequently if deemed appropriate by the Board, the Company shall submit to the Adviser, and the Adviser shall at least annually submit to the Board, such reports, materials and data as the Board may reasonably request so that the Board may finally carry out the obligations imposed upon it by the conditions contained in the Shared Funding Exemption Order; and said reports, materials and data shall be submitted more frequently if deemed appropriate by the Board. The responsibility to report such information and conflicts to the Board will be carried out with a view only to the interests of the contract owners.

7.3 If it is determined by a majority of the Board, or a majority of its disinterested members, that a material irreconcilable conflict exists, the Company and any other Participating Insurance Companies shall, at their expense and to the extent reasonably practicable (as determined by a majority of the disinterested Board members), take whatever steps are necessary to remedy or eliminate the irreconcilable material conflict, up to and including: (a) withdrawing the assets allocable to some or all of the separate accounts from the Fund or any Designated Portfolio and reinvesting such assets in a different investment medium, which may include another Designated Portfolio of the Fund, or submitting to a vote of all affected contract owners the question whether such segregation should be implemented 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.

7.4 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 any Designated Portfolio and terminate this Agreement with respect to such Account provided, however, that such withdrawal and termination shall be limited to the extent required by the foregoing material irreconcilable conflict as determined by a majority of the disinterested members of the Board. The Company will bear the cost of any remedial action, including such withdrawal and termination. No penalty will be imposed by the Fund upon the affected Account for withdrawing assets from the Fund in the event of a material irreconcilable conflict. 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 effective date of such termination the Fund shall continue to accept and implement orders by the Company for the purchase (and redemption) of shares of such Designated Portfolio.

7.5 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 affected Designated Portfolio and terminate this Agreement with respect to such Account within six months after the Board informs the Company in writing that it has determined that such decision has created an irreconcilable material conflict; provided, however, that such withdrawal and termination shall be limited to the extent required by the foregoing material irreconcilable conflict as determined by a majority of the disinterested members of the Board. Until the effective date of such termination, the Fund shall continue to accept and implement orders by the Company for the purchase (and redemption) of shares of such Designated Portfolios.

7.6 For purposes of Sections 7.3 through 7.6 of this Agreement, a majority of the disinterested members of the Board 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 7.3 to establish a new funding medium for the Contract 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 Board determines that any proposed action

does not adequately remedy any irreconcilable material conflict, then the Company will withdraw an Account’s investment in any Designated Portfolio and terminate this Agreement within six (6) months after the Board informs the Company in writing of the foregoing determination; provided, however, that such withdrawal and termination shall be limited to the extent required by any such material irreconcilable conflict as determined by a majority of the disinterested members of the Board.

7.7 If and to the extent that Rule 6e-2 and Rule 6e-3(T) of the 1940 Act 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 Shared Funding Exemption Order) on terms and conditions materially different from those contained in the Shared Funding Exemption Order, then (a) the Fund and/or the Participating Insurance Companies, as appropriate, shall take such steps as may be necessary to comply with Rules 6e-2 and 6e-3(T), as amended, and Rule 6e-3, as adopted, to the extent such rules are applicable; and (b) Sections 3.4, 3.5, 3.6, 7.1, 7.2, 7.3, 7.4 and 7.5 of this Agreement shall continue in effect only to the extent that terms and conditions substantially identical to such Sections are contained in such Rule(s) as so amended or adopted.

ARTICLE VIII

(i)

arise out of or are based upon any untrue statements or alleged untrue statements of any material fact contained in the Registration Statement, prospectus, or statement of additional information for the Contracts or contained in the Contracts or sales literature 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 in writing to the Company by or on behalf of the Fund, the Adviser or the Underwriter for use in the

			Registration Statement, prospectus or statement of additional information for the Contracts or in the Contracts or sales literature for the Contracts (or any amendment or supplement) or otherwise for use in connection with the sale of the Contracts or shares of the Designated Portfolios; or

	(ii)		arise out of or as a result of statements or representations (other than statements or representations contained in the Registration Statement, prospectus, SAI or sales literature of the Fund not supplied by the Company or persons under its control) or wrongful conduct of the Company or persons under its control, with respect to the sale or distribution of the Contracts or shares of the Designated Portfolios; or

	(iii)		arise out of any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, prospectus, SAI or sales literature of the Fund or any amendment thereof or supplement thereto or the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading if such a statement or omission was made in reliance upon and in conformity with information furnished to the Fund by or on behalf of the Company; or

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

	(v)		(vi) arise out of or result from any material breach of any representation and/or warranty made by the Company in this Agreement or arise out of or result from any other material breach of this Agreement by the Company;

as limited by and in accordance with the provisions of Sections 8.1(b) and 8.1(c) hereof.

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

(c) The Company shall not be liable under this indemnification provision with respect to any claim made against an Indemnified Party unless such Indemnified Party shall have notified the Company in writing within a reasonable time after the summons or other first legal process giving information of the nature of the claim shall have been served upon such Indemnified Party (or after such Indemnified Party shall have received notice of such service on any designated agent), but failure to notify the Company of any such claim shall not relieve the

Company from any liability that it may have to the Indemnified Party against whom such action is brought otherwise than on account of this indemnification provision, except to the extent that the Company has been prejudiced by such failure to give notice. In case any such action is brought against an Indemnified Party, the Company shall be entitled to participate, at its own expense, in the defense of such action. The Company also shall be entitled to assume the defense thereof, with counsel satisfactory to the party named in the action and to settle the claim at its own expense provided, however, that no such settlement shall, without the Indemnified Parties’ written consent, include any factual stipulation referring to the Indemnified Parties or their conduct. After notice from the Company to such party of the Company’s election to assume the defense thereof, the Indemnified Party shall bear the fees and expenses of any additional counsel retained by it, and the Company will not be liable to such party under this Agreement for any legal or other expenses subsequently incurred by such party independently in connection with the defense thereof other than reasonable costs of investigation.

(d) The Indemnified Parties will promptly notify the Company of (i) the issuance by any court or regulatory body of any stop order, cease and desist order, or other similar order with respect to the Fund’s registration statement under the 1933 Act or prospectus, (ii) any request by the SEC for any amendment to such registration statement or prospectus that may affect the offering of shares of the Fund, (iii) the initiation of any litigation or proceedings for that purpose or for any other purpose relating to the registration or offering of the Fund’s shares, or (iv) any other action or circumstances that may prevent the lawful offer or sale of shares of any Fund in any state or jurisdiction, including, without limitation, any circumstances in which (a) such shares are not registered and, in all material respects, issued and sold in accordance with applicable state and federal law, or (b) such law precludes the use of such shares as an underlying investment medium of the Contracts issued or to be issued by the Company. The Fund and Adviser will make every reasonable effort to prevent the issuance, with respect to any Designated Portfolio, of any such stop order, cease and desist order or similar order and, if any such order is issued, to obtain the lifting thereof at the earliest possible time.

8.2 Indemnification by the Underwriter and the Adviser

(a) The Underwriter and the Adviser agree to indemnify and hold harmless the Company and its affiliated broker-dealer and each of their directors and officers and each person, if any, who controls the Company or its broker-dealer subsidiary within the meaning of Section 15 of the 1933 Act (collectively, the “Indemnified Parties” for purposes of this Section 8.2) against any and all losses, claims, damages, liabilities (including amounts paid in settlement with the written consent of the Underwriter) or litigation (including reasonable legal and other expenses) to which the Indemnified Parties may become subject under any statute or regulation, at common law or otherwise, insofar as such losses, claims, damages, liabilities or expenses (or actions in respect thereof) or settlements are related to the sale or acquisition of shares of the Designated Portfolios or the Contracts; and

	(ii)		arise out of or as a result of statements or representations (other than statements or representations contained in the Registration Statement, prospectus, SAI or sales literature for the Contracts not supplied by the Fund, Adviser or Underwriter or persons under the control of any of them) or wrongful conduct of the Fund, Adviser or Underwriter or person under the control of any of them with respect to the sale or distribution of the Contracts or shares of the Designated Portfolios; or

	(iii)		arise out of any untrue statement or alleged untrue statement of a material fact contained in a Registration Statement, prospectus, SAI or sales literature for the Contracts, or any amendment thereof or supplement thereto, or the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, if such statement or omission was made in reliance upon and in conformity with information furnished to the Company by or on behalf of the Fund, Adviser or Underwriter; or

(c) The Underwriter and the Adviser shall not be liable under this indemnification provision with respect to any claim made against an Indemnified Party unless such Indemnified Party shall have notified the Underwriter or the Adviser in writing within a reasonable time after the summons or other first legal process giving information of the nature of the claim shall have been served upon such Indemnified Party (or after such Indemnified Party shall have received notice of such service on any designated agent), but failure to notify the Underwriter or the Adviser of any such claim shall not relieve the Underwriter or the Adviser from any liability which it may have to the Indemnified Party against whom such action is brought otherwise than on account of this indemnification provision, except to the extent that the Underwriter or the Adviser has been prejudiced by such failure to give notice. In case any such action is brought against an Indemnified Party, the Underwriter or the Adviser will be entitled to participate, at its own expense, in the defense thereof. The Underwriter and the Adviser also shall be entitled to assume the defense thereof, with counsel satisfactory to the party named in the action and to settle the claim at its own expense; provided, however, that no such settlement shall, without the Indemnified Parties’ written consent, include any factual stipulation referring to the Indemnified Parties or their conduct. After notice from the Underwriter or the Adviser to such party of the Underwriter’s or the Adviser’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 Underwriter or the Adviser 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.
