PARTICIPATION AGREEMENT

THIS AGREEMENT, made and entered into as of the 15th day of December, 2004 (“Agreement”), by and among Principal Life Insurance Company, an Iowa life insurance company (“Insurer”), and Princor Financial Services Corporation, (“Contracts Distributor”), the principal underwriter with respect to the Contracts referred to below (collectively, Insurer and Contracts Distributor are referred to as the “Company”); Alliance Capital Management L.P., a Delaware limited partnership (“Adviser”), the investment adviser of the Fund referred to below; and AllianceBernstein Investment Research And Management, Inc., a Delaware corporation (“Distributor”), the Fund’s principal underwriter (collectively, the “Parties”),

WITNESSETH THAT:

WHEREAS the Company, the Distributor, and AllianceBernstein Variable Products Series Fund, Inc. (the “Fund”) desire that Class A shares (“shares”) of the Fund’s Portfolios listed on Schedule A (the “Portfolios”; reference herein to the “Fund” includes reference to each Portfolio to the extent the context requires) be made available by Distributor to serve as underlying investment media for those combination fixed and variable annuity contracts of the Insurer that are the subject of Insurer’s Form N-4 registration statement filed with the Securities and Exchange Commission (the “SEC”), File No. 811-02091 (the “Contracts”), to be offered through Contracts Distributor and other registered broker-dealer firms as agreed to by the Company; and

WHEREAS the Contracts provide for the allocation of net amounts received by the Company to separate series (the “Divisions”); of the Insurer’s “Separate Accounts” (as shown on

Schedule A-l) for investment in the shares of corresponding Portfolios of the Fund that are made available through the Separate Account to act as underlying investment media,

NOW, THEREFORE, in consideration of the mutual benefits and promises contained herein, the Fund and Distributor will make shares of the Portfolios available to the Company for this purpose at net asset value and with no sales charges, all subject to the following provisions:

Section 1. Additional Portfolios

The Fund has and may, from time to time, add additional Portfolios, which will become subject to this Agreement, if, upon the written consent of each of the Parties hereto, they are made available as investment media for the Contracts.

Section 2. Processing Transactions

2.1 Timely Pricing and Orders.

The Adviser or its designated agent will provide closing net asset value, dividend and capital gain information for each Portfolio to Insurer at the close of trading on each day (a “Business Day”) on which (a) the New York Stock Exchange is open for regular trading, (b) the Fund calculates the Portfolio’s net asset value and (c) Insurer is open for business. The Fund or its designated agent will use its best efforts to provide this information by 6:00 p.m., Eastern time. Insurer will use these data to calculate unit values, which in turn will be used to process transactions that receive that same Business Day’s Separate Account Division’s unit values. Such Separate Account processing will be done the same evening, and corresponding orders with

respect to Fund shares will be placed the morning of the following Business Day. The Company will use its best efforts to place such orders with the Fund by 10:00 a.m., Eastern time. The parties agree to modify the provisions of this paragraph as necessary to comply with changes in applicable law.

2.2 Timely Payments.

The Company will transmit orders for purchases and redemptions of Fund shares to Distributor, and will wire payment for net purchases to a custodial account designated by the Fund on the day the order for Fund shares is placed, to the extent practicable. Payment for net redemptions will be wired by the Fund to an account designated by the Company on the same day as the order is placed, to the extent practicable, and in any event be made within six calendar days after the date the order is placed in order to enable the Company to pay redemption proceeds within the time specified in Section 22(e) of the Investment Company Act of 1940, as amended (the “1940 Act”).

2.3 Redemption in Kind.

The Fund reserves the right to pay any portion of a redemption in kind of portfolio securities, if the Fund’s board of directors (the “Board of Directors”) determines that it would be detrimental to the best interests of shareholders to make a redemption wholly in cash.

2.4 Applicable Price.

The Parties agree that Portfolio share purchase and redemption orders by owners of the Contracts (“Contractowners”) resulting from their purchase payments, surrenders, partial withdrawals, routine withdrawals of charges, or other transactions under the Contracts will be executed at the net asset values as determined as of the close of regular trading on the New York

Stock Exchange (the “Close of Trading”) on the Business Day that the Company receives such orders and processes such transactions. Subject to the right of the Fund to reject any order, orders received by the Company prior to the Close of Trading on any Business Day and transmitted to the Distributor by 8:00 a.m. New York Time on the next Business Day will be executed by the Distributor at the net asset value determined as of the Close of Trading on the Business Day the order was received by the Company. For the purposes of this section, the Company shall be deemed to be the agent of the Fund for receipt of such orders from holders or applicants of contracts, and receipt by the Company shall constitute receipt by the Fund. Any orders received by the Company after the Close of Trading on a Business Day and all orders that are transmitted to the Distributor after 8:00 a.m. New York City time on the next Business Day, will be executed by the Distributor at the net asset value next determined. The Company hereby represents and warrants that it has adopted and implemented internal controls reasonably designed to prevent orders received after the Close of Trading on any Business Day from being submitted to the Distributor as or with orders received prior to the Close of Trading on such Business Day. The Company hereby elects to reinvest all dividends and capital gains distributions in additional shares of the corresponding Portfolio at the record-date net asset values until the Company otherwise notifies the Fund in writing, it being agreed by the Parties that the record date and the payment date with respect to any dividend or distribution will be the same Business Day. The parties agree to modify the provisions of this paragraph as necessary to comply with changes in applicable law.

Section 3. Costs and Expenses

3.1 General.

Except as otherwise specifically provided herein, each Party will bear all expenses incident to its performance under this Agreement.

3.2 Registration.

The Fund will bear the cost of its registering as a management investment company under the 1940 Act and registering its shares under the Securities Act of 1933, as amended (the “1933 Act”), and keeping such registrations current and effective; including, without limitation, the preparation of and filing with the SEC of Forms N-SAR, N-CSR, and Rule 24f-2 Notices respecting the Fund and its shares and payment of all applicable registration or filing fees with respect to any of the foregoing. The Company will bear the cost of registering the Separate Account as a unit investment trust under the 1940 Act and registering units of interest under the Contracts under the 1933 Act and keeping such registrations current and effective; including, without limitation, the preparation and filing with the SEC of Forms N-SAR and Rule 24f-2 Notices respecting the Separate Account and its units of interest and payment of all applicable registration or filing fees with respect to any of the foregoing.

3.3 Other (Non-Sales-Related) Expenses.

The Fund will bear the costs of preparing, filing with the SEC and setting for printing the Fund’s prospectus, statement of additional information and any amendments or supplements thereto (collectively, the “Fund Prospectus”), periodic reports to shareholders, Fund proxy material and other shareholder communications and any related requests for voting instructions from Participants (as defined below). The Company will bear the costs of preparing, filing with the SEC and setting for printing, the Separate Account’s prospectus, statement of additional information and any amendments or supplements thereto (collectively, the “Separate Account Prospectus”), any

periodic reports to owners, annuitants or participants under the Contracts (collectively, “Participants”), and other Participant communications.

Distributor and the Fund will make every reasonable effort to prevent the issuance 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.

(b) The Company shall immediately notify the Fund of (i) the issuance by any court or regulatory body of any stop order, cease and desist order or similar order with respect to the Separate Account’s registration statement under the 1933 Act relating to the Contracts or the Separate Account Prospectus, (ii) any request by the SEC for any amendment to such registration statement or Separate Account Prospectus, (iii) the initiation of any proceedings for that purpose or for any other purpose relating to the registration or offering of the Separate Account interests pursuant to the Contracts, or (iv) any other action or circumstances that may prevent the lawful offer or sale of said interests in any state or jurisdiction, including, without limitation, any circumstances in which said interests are not registered and, in all material respects, issued and sold in accordance with applicable state and federal law.

4.7 Market Timing

The Company agrees that it will take any and all actions reasonably necessary to ensure the compliance by Contractowners with the Fund’s policies prohibiting “market timing,” as set forth in the Fund’s current prospectus. In the event that it should come to the Company’s attention that any Contractowner is engaging in a pattern of purchases, redemptions and/or exchanges of shares of a Fund that may evidence “market timing,” the Company shall notify the Distributor of such pattern. The Company agrees to cooperate fully with the Distributor for the purpose of preventing “market timing”, and will furnish to the Distributor such information as Distributor may consider necessary or desirable to review the possible existence and extent of “market timing” by any Contractowner. The Company will take any and all such actions, to the extent permitted by law, as the Distributor may reasonably request in order to terminate any pattern of trading that the Distributor considers to be “market timing,” including, without limitation, refusing the orders of any Contractowner to purchase or exchange shares of the Fund.

Section 5. Mixed and Shared Funding

5.1 General.

The Fund has obtained an order exempting it from certain provisions of the 1940 Act and rules thereunder so that the Fund is available for investment by certain other entities, including, without limitation, separate accounts funding variable life insurance policies and separate accounts of insurance companies unaffiliated with Insurer (“Mixed and Shared Funding Order”). 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.

5.2 Disinterested Directors.

The Fund 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 Adviser or Distributor within the meaning of Section 2(a)(19) of the 1940 Act.

5.3 Monitoring for Material Irreconcilable Conflicts.

The Fund agrees that its Board of Directors will monitor for the existence of any material irreconcilable conflict between the interests of the participants in all separate accounts of life insurance companies utilizing the Fund, including the Separate Account. The Company agrees to inform the Board of Directors of the Fund of the existence of or any potential for 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 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;

(d) the manner in which the investments of any Portfolio are being managed;

(e) a difference in voting instructions given by variable annuity contract and variable life insurance contract participants or by participants of different life insurance companies utilizing the Fund; or

(f) a decision by a life insurance company utilizing the Fund to disregard the voting instructions of participants.

The 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 the Company to disregard voting instructions of Participants.

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, the Company and the other life insurance companies utilizing the Fund will, at their 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 separate accounts from the Fund or any Portfolio and reinvesting such assets in a different investment medium, including another Portfolio of the Fund, or submitting the question whether such segregation should be implemented to a vote of all affected participants and, as appropriate, segregating the assets of any particular group (e.g., annuity contract owners or participants, life insurance contract owners or all contract owners and participants of one or more life insurance companies utilizing the Fund) that votes in favor of such segregation, or offering to the affected contract owners or participants 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 Insurer’s decision to disregard Participant 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 Separate Account’s investment in the Fund. No charge or penalty will be imposed as a result of such withdrawal. Any such withdrawal must take place within six months after the Fund gives notice to Insurer that this provision is being implemented, and until such withdrawal Distributor and the Fund

shall continue to accept and implement orders by Insurer for the purchase and redemption of shares of the Fund.

(c) If a material irreconcilable conflict arises because a particular state insurance regulator’s decision applicable to Insurer conflicts with the majority of other state regulators, then Insurer will withdraw the Separate Account’s investment in the Fund within six months after the Fund’s Board of Directors informs Insurer that it has determined that such decision has created a material irreconcilable conflict, and until such withdrawal Distributor and Fund shall continue to accept and implement orders by the Company for the purchase and redemption of shares of the Fund.

(d) The 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 Participants.

(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 the Fund or Distributor be required to establish a new funding medium for any Contracts. The 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 Participants materially adversely affected by the material irreconcilable conflict.

5.5 Notice to the Company.

The Fund will promptly make known in writing to the 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.

The Company and the Fund will at least annually submit to the Board of Directors of the Fund 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 upon it by the provisions hereof, 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 life insurance companies utilizing the Fund 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 the Fund is serving an investment medium for variable life insurance policies, 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, the Parties agree that they 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.

Section 6. Termination

Subject to the cost allocation procedures set forth in Section 3 hereof, Insurer will distribute all proxy material furnished by the Fund to Participants and will vote Fund shares in accordance with instructions received from Participants. The Company will vote Fund shares that are (a) not attributable to Participants or (b) attributable to Participants, but for which no instructions have been received, in the same proportion as Fund shares for which said instructions have been received from Participants. The Company agrees that it will disregard Participant voting instructions only to the extent it would be permitted to do so pursuant to Rule 6e-3 (T)(b)(15)(iii) under the 1940 Act if the Contracts were variable life insurance policies subject to that rule. Other participating life insurance

companies utilizing the Fund will be responsible for calculating voting privileges in a manner consistent with that of Insurer, as prescribed by this Section 10.

(i)

arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in the Separate Account’s 1933 Act registration

			statement, the Separate Account Prospectus, the Contracts or, to the extent prepared by Insurer or Contracts Distributor, 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 Insurer or Contracts Distributor by or on behalf of the Fund, Distributor or Adviser for use in the Separate Account’s 1933 Act registration statement, the Separate Account Prospectus, the Contracts, or sales literature or advertising (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 the Fund’s 1933 Act registration statement, Fund Prospectus, sales literature or advertising of the Fund, or any amendment or supplement to any of the foregoing, not supplied for use therein by or on behalf of Insurer or Contracts Distributor) or the negligent, illegal or fraudulent conduct of the Company or Contracts Distributor 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 the NASD’s By-Laws), in connection with the sale or distribution of the Contracts or Fund shares; or

			(iii) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in the Fund’s 1933 Act registration statement, Fund Prospectus, sales literature or advertising of the Fund, 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 the Fund, Adviser or Distributor by or on behalf of Insurer or Contracts Distributor for use in the Fund’s 1933 Act registration statement, Fund Prospectus, sales literature or advertising of the Fund, or any amendment or supplement to any of the foregoing; or

	(iv)		arise as a result of any failure by Insurer or Contracts Distributor to perform the obligations, provide the services and furnish the materials required of them under the terms of this Agreement.

(b) The 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 that Indemnified Party of its duties or by reason of that Indemnified Party’s reckless disregard of obligations or duties under this Agreement or to Distributor or to the Fund.

(c) The Company shall not be liable under this Section 12.1 with respect to any action against an Indemnified Party unless the Fund, Distributor or Adviser shall have notified Insurer 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 Insurer of any such action shall not relieve Insurer 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. 1. In case any such action is brought against an Indemnified Party, Insurer shall be entitled to participate, at its own expense, in the defense of such action. Insurer 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 delayed or withheld. After notice from Insurer to such Indemnified Party of Insurer’s election to assume the defense thereof, the Indemnified Party will cooperate fully with Insurer and shall bear the fees and expenses of any additional counsel retained by it, and Insurer 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 Indemnification of Insurer and Contracts Distributor by Adviser.

(a) Except to the extent provided in Sections 12.2(d) and 12.2(e), below, Adviser agrees to indemnify and hold harmless Insurer and Contracts Distributor, each of their directors and officers, and each person, if any, who controls Insurer or Contracts Distributor within the meaning of Section 15 of the 1933 Act (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 Adviser) 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, at

common law or otherwise, insofar as such losses, claims, damages, liabilities or actions are related to the sale, acquisition, or holding of the Fund’s shares and:

	(i)		arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in the Fund’s 1933 Act registration statement, Fund Prospectus, sales literature or advertising of the Fund or, to the extent not prepared by Insurer or Contracts Distributor, 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 Distributor, Adviser or the Fund by or on behalf of Insurer or Contracts Distributor for use in the Fund’s 1933 Act registration statement, Fund Prospectus, or in sales literature or advertising (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 the Separate Account’s 1933 Act registration statement, Separate 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 Distributor, Adviser, or the Fund) or the negligent, illegal or fraudulent conduct of the Fund, Distributor, Adviser or persons under their

			control (including, without limitation, their employees and Associated Persons), in connection with the sale or distribution of the Contracts or Fund shares; or

	(iii)		arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in the Separate Account’s 1933 Act registration statement, Separate Account 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 Insurer or Contracts Distributor by or on behalf of the Fund, Distributor or Adviser for use in the Separate Account’s 1933 Act registration statement, Separate Account 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 the Fund, Adviser or Distributor to perform the obligations, provide the services and furnish the materials required of them under the terms of this Agreement;

(b) Except to the extent provided in Sections 12.2(d) and 12.2(e) hereof, Adviser agrees 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, except as set forth in Section 12.2(c) below, the written consent of Adviser) 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 Portfolio to operate as a regulated investment company in compliance with (i) Subchapter M of the Code and regulations thereunder and (ii) Section 817(h) of the Code and regulations thereunder (except to the extent that such failure is caused by Insurer), including, without limitation, any income taxes and related penalties, rescission charges, liability under state law to Contract owners or Participants asserting liability against Insurer or Contracts Distributor pursuant to the Contracts, the costs of any ruling and closing agreement or other settlement with the Internal Revenue Service, and the cost of any substitution by Insurer of shares of another investment company or portfolio for those of any adversely affected Portfolio as a funding medium for the Separate Account that Insurer deems necessary or appropriate as a result of the noncompliance.

(c) The written consent of Adviser referred to in Section 12.2(b) above shall not be required with respect to amounts paid in connection with any ruling and closing agreement or other settlement with the Internal Revenue Service.

(d) Adviser shall not 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 or to Insurer, Contracts Distributor or the Separate Account.

(e) Adviser shall not be liable under this Section 12.2 with respect to any action against an Indemnified Party unless Insurer or Contracts Distributor shall have notified Adviser 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 Adviser of any such action shall not relieve Adviser 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. In case any such action is brought against an Indemnified Party, Adviser will be entitled to participate, at its own expense, in the defense of such action. Adviser also shall be entitled to assume the defense thereof (which shall include, without limitation, the conduct of any ruling request and closing agreement or other settlement proceeding with the Internal Revenue Service), with counsel approved by the Indemnified Party named in the action, which approval shall not be unreasonably withheld. After notice from Adviser to such Indemnified Party of Adviser’s election to assume the defense thereof, the Indemnified Party will cooperate fully with Adviser and shall bear the fees and expenses of any additional counsel retained by it, and Adviser 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.

12.3 Effect of Notice.

Any notice given by the indemnifying Party to an Indemnified Party referred to in Section 12.1(c) or 12.2(e) 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.

Section 13. Applicable Law

This Agreement will be construed and the provisions hereof interpreted under and in accordance with New York law, without regard for that state’s principles of conflict of laws.

Section 14. Execution in Counterparts

This Agreement may be executed simultaneously in two or more counterparts, each of which taken together will constitute one and the same instrument.

Section 15. Severability

If any provision of this Agreement is held or made invalid by a court decision, statute, rule or otherwise, the remainder of this Agreement will not be affected thereby.

Section 16. Rights Cumulative

Section 18. Headings

Advisor’s and Distributor’s consent will terminate with the termination of this Agreement. Advisor or Distributor may withdraw this consent as to any particular use of any such name or identifying marks at any time (i) upon Advisor’s or Distributor’s reasonable determination that such use would have a material adverse effect on the reputation or marketing efforts of Advisor, Distributor or Funds or (ii) if no series or class of shares continues to be offered through variable insurance contracts issued by the Company; provided however, that the Company may continue to use materials prepared or printed prior to the withdrawal of such authorization, and provided further
