WHEREAS, the beneficial interest in the Fund is divided into several series of shares, each designated a “Portfolio,” and representing the interest in a particular managed portfolio of securities and other assets; and

WHEREAS, the Fund is registered as an open-end management investment company under the Investment Company Act of 1940, as amended (the “1940 Act”) and its shares are registered under the Securities Act of 1933, as amended (the “1933 Act”); and

WHEREAS, the assets of each Portfolio of the Fund are managed by several entities (the “Advisers”), each of which is duly registered as an investment adviser under the federal Investment Advisers Act of 1940 and any applicable state securities laws; and

WHEREAS, the Company and the Sponsor have entered into a Vanguard Daily Valuation Agency Agreement dated as of September 14, 1999 (the “Agency Agreement”), which sets forth the operational provisions governing the purchase and redemption of shares of the Fund by the Accounts and related matters;

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

ARTICLE I. Sale of Fund Shares

1.1 The Sponsor and the Distributor agree to sell to the Company those shares of the Portfolios of the Fund listed on Schedule B that each Account orders, in accordance with the Agency Agreement.

1.2 The Fund, subject to the provisions of Article IX of this Agreement, agrees to make its shares available indefinitely for purchase at the applicable net asset value per share by the Company and its Accounts on those days on which the Fund calculates its net asset value pursuant to the rules of the SEC and the Fund shall use its best efforts to calculate such net asset value on each day which the New York Stock Exchange is open for trading.

Notwithstanding the foregoing, the Board of Trustees of the Fund (hereinafter the “Board”) may refuse to sell shares of any Portfolio to any person including, but not limited to, the Company, 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 Board, acting in good faith and in light of their fiduciary duties under federal and any applicable state laws, necessary in the best interests of the shareholders of such Portfolio. Further, it is acknowledged and agreed that the availability of shares of the Fund shall be subject to the Fund’s then current prospectus and statement of additional information, federal and state securities laws and applicable rules and regulations of the SEC and the NASD.

1.3 The Fund and the Sponsor agree that shares of the Fund will be sold only to Participating Insurance Companies and their separate accounts. No shares of any Portfolio will be sold to the general public.

1.4 The Fund and the Sponsor will not sell Fund shares to any Participating Insurance Company or its separate account unless an agreement containing a provision substantially the same as Section 2.6 of Article II of this Agreement is in effect to govern such sales.

1.5 The Fund agrees to redeem for cash, on the Company’s request, any full or fractional shares of the Fund held by an Account, in accordance with the Agency Agreement. The Fund reserves the right to suspend redemption privileges or pay redemptions in kind, as disclosed in the Fund’s prospectus or statement of additional information. The Fund agrees to treat the Company like any other shareholder in similar circumstances in making these determinations.

1.6 The Company agrees to purchase and redeem the shares of each Portfolio offered by the then current prospectus of the Fund and in accordance with the provisions of such prospectus and the accompanying statement of additional information.

1.7 Issuance and transfer of a Fund’s shares will be by book entry only. Stock certificates will not be issued to the Company or any Account. Shares ordered from the Fund will be recorded in an appropriate title for each Account or the appropriate subaccount of each Account. The Fund shall furnish to the Company the CUSIP number assigned to each Portfolio of the Fund identified in Schedule B hereto.

1.8 The Company hereby elects to receive all income, dividends and capital gain distributions as are payable on the Portfolio shares in additional shares of that Portfolio. The Company reserves the right to revoke this election and to receive all such income dividends and capital gain distributions in cash. The Fund shall notify the Company of the number of shares so issued as payment of dividends and distributions.

1.9 EXTRAORDINARY EVENTS. Notwithstanding anything to the contrary in the Agency Agreement, the Company is not authorized to accept as the Fund’s agent any individual purchase or redemption of shares in an amount which equals or exceeds the “Large Transaction Amount” for a Portfolio (as specified in Schedule C) where such order is the result of an “Extraordinary Event” of which the Company is aware, unless the Company has notified the Sponsor of such order as soon as practicable following the Company becoming aware of the Extraordinary Event and, with respect to purchases or redemptions of which the Company is aware as of 3:00 p.m. Eastern time on the trade date, in no event later than 3:00 p.m. Eastern time on the trade date. For these purposes, an “Extraordinary Event” shall mean an event outside normal operations such as an entire Account moving into or out of a Portfolio or an asset transfer arising from a merger, acquisition or divestiture. The Sponsor reserves the right to refuse any purchase order, or to delay settlement of any redemption order, which equals or exceeds the applicable Large Transaction Amount and results from an Extraordinary Event, which the Sponsor, in its sole discretion, deems disruptive or detrimental to the applicable Portfolio. The Sponsor reserves the right to amend or revise Schedule C at any time and will provide at least 24 hours’ advance notice of such revision to the Company.

ARTICLE II. Representations and Warranties

2.1 The Company represents and warrants that it is an insurance company duly organized and in good standing under applicable law; that it has legally and validly established each Account prior to any issuance or sale thereof as a segregated asset account under Section 733.220 of the Oregon Insurance Code; that it has and will maintain the capacity to issue all Variable Insurance Products that may be sold; and that it is properly licensed, qualified and in good standing to sell the Variable Insurance Products in all fifty states and the District of Columbia.

2.2 The Company represents and warrants that the Variable Insurance Products are registered under the 0000 Xxx.

2.3 The Company represents and warrants it has registered each Account as a unit investment trust in accordance with the provisions of the 1940 Act to serve as segregated investment accounts for the Variable Insurance Products.

2.4 The Fund represents and warrants that Fund shares sold pursuant to this Agreement shall be registered under the 1933 Act, duly authorized for issuance and sold in compliance with the laws of the State of Oregon and all applicable federal and state securities laws and that the Fund is and shall remain registered under the 0000 Xxx. 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, the Distributor, or the Sponsor.

2.5 The Fund represents that it is qualified as a Regulated Investment Company under Subchapter M of the Internal Revenue Code of 1986, as amended (the “Code”), and that it will make every effort to maintain qualification (under Subchapter M or any successor or similar provision) and (ii) it will notify the Company immediately upon having a reasonable basis for believing that it ceased to so qualify or that it might not so qualify in the future. The Fund acknowledges that any failure to qualify as a Regulated Investment Company will eliminate the ability of the subaccounts to avail themselves of the “look through” provisions of Section 817(h) of the Code, and that as a result the Variable Insurance Products will almost certainly fail to qualify as endowment or life insurance contracts under Section 817(h) of the Code.

2.6 The Company represents that the Variable Insurance Products will be treated as endowment or life 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 and the Sponsor immediately upon having a reasonable basis for believing that the Variable Insurance Products have ceased to be so treated or that they might not be so treated in the future.

2.7 The Fund currently does not intend to make any payments to finance distribution expenses pursuant to Rule 12b-1 under the 1940 Act or otherwise.

2.8 The Fund makes no representation as to whether any aspect of its operations (including, but not limited to, fees and expenses and investment policies) complies with the insurance laws or regulations of the various states except that the Fund represents that the Fund’s investment policies, fees and expenses are and shall at all times remain in compliance with the laws of the State of Oregon and the Fund and the Sponsor represent that their respective operations are and shall at all times remain in material compliance with the laws of the State of Oregon to the extent required to perform this Agreement.

2.9 The Distributor represents and warrants that it is a member in good standing of the NASD and is registered as a broker-dealer with the SEC. The Distributor further represents that it will sell and distribute the Fund shares in accordance with the laws of the State of Oregon and all applicable state and federal securities laws, including without limitation the 1933 Act, the 1934 Act, and the 0000 Xxx.

2.10 The Fund represents that it is lawfully organized and validly existing under the laws of the State of Delaware and that it does and will comply in all material respects with the 1940 Act and any applicable regulations thereunder.

2.11 The Sponsor represents and warrants that the Advisers to the Fund are, and the Sponsor shall use its best effort to cause the Advisers to remain, duly registered in all material respects under all applicable federal and state securities laws and to perform their obligations for the Fund in compliance in all material respects with the laws of the State of Oregon and any applicable state and federal securities laws.

2.12 The Fund and the Sponsor represent and warrant that all of their trustees, directors, officers, employees, investment advisers, and other individuals/entities dealing with the money and/or securities of the Fund are and shall continue to be at all times covered by a blanket fidelity bond or similar coverage for the benefit of the Fund in an amount not less than the minimum coverage required currently by Rule 17g-1 under the 1940 Act or other applicable laws or regulations 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 bonding company.

2.13 With respect to the Variable Insurance Products, which are registered under the 1933 Act, the Company represents and warrants that:

(a)

StanCorp Equities, Inc. is the principal underwriter for each such Account and any subaccounts thereof and is a registered broker-dealer with the SEC under the 1934 Act;

(b)

the shares of the Portfolios of the Fund are and will continue to be the only investment securities held by the corresponding subaccounts;

(c)

the number of Portfolios of the Fund available for investment by the Accounts will not constitute a majority of the total number of mutual funds or portfolio selections available for investment by the Accounts in any Variable Insurance Product that is a variable annuity; and

(d)

with regard to each Portfolio, the Company, if permitted by law, on behalf of the corresponding subaccount, will:

(i)

vote such shares held by it in the same proportion as the vote of all other holders of such shares; and

(ii)

refrain from substituting shares of another security for such shares unless the SEC has approved such substitution in the manner provided in Section 26 of the 1940 Act, or the Variable Insurance Products otherwise allow such substitution and SEC approval is not required.

2.14 The Fund represents that it will comply with all provisions of the 1940 Act requiring voting by shareholders, and in particular the Fund will either provide for annual meetings or comply with Section 16(c) of the 1940 Act (although the Fund is not one of the trusts described in Section 16(c) of that Act) as well as with Sections 16(a) and, if and when applicable, 16(b). Further, the Fund will act in accordance with the SEC’s interpretation of the requirements of Section 16(a) with respect to periodic elections of trustees and with whatever rules the SEC may promulgate with respect thereto.

3.3 The Fund, at its own expense, shall provide the Company with copies of its reports to shareholders, other communications to shareholders, and, if required by applicable law, proxy material, in such quantity as the Company shall reasonably require for distributing to Variable Insurance Product owners. The Fund shall provide to the Company the prospectuses and annual reports referenced in this Agreement within fifteen (15) days prior to the Company’s obligation to mail, and the Company agrees to provide the Fund with advance notice of such date.

The Fund also shall be entitled to assume the defense thereof, with counsel satisfactory to the party named in the action. After notice from the Fund to such party or the Fund’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 Fund will not be liable to such party independently in connection with the defense thereof other than reasonable costs of litigation.

(d) The Company and the Sponsor agree promptly to notify the Fund of the commencement of any litigation or proceedings against it or any of its respective officers or directors in connection with this Agreement, the issuance or sale of the Variable Insurance Products, with respect to the operation of an Account, or the sale or acquisition of shares of the Fund.

7.4 Indemnification by the Distributor

(a) The Distributor agrees to indemnify and hold harmless the Company and each of its directors and officers and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act (collectively, the “Indemnified Parties” for purposes of this Section 7.4) against any and all losses, claims, damages, liabilities (including amounts paid in settlement with the written consent of the Sponsor) or litigation (including 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 expenses (or actions in respect thereof) or settlements are related to the sale or acquisition of the Fund’s shares or the Variable Insurance Products and:

(i)

arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in the registration statement or prospectus or sales literature of the Fund (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 the Distributor or the Fund by or on behalf of the Company for use in the registration statement or prospectus for the Fund or in sales literature (or any amendment or supplement thereto) or otherwise for use in connection with the sale of the Variable Insurance Products or Fund shares; or

(ii)

arise out of or as a result of statements or representations (other than statements or representations contained in the registration statement, prospectus or sales literature for the Variable Insurance Products not supplied by the Distributor or persons under its control) or unlawful conduct of the Fund, the Advisers or persons under their control, with respect to the sale or distribution of the Variable Insurance Products or Fund shares; or

(iii)

(iv)

result from any failure by the Distributor or the Fund to provide the services and furnish the materials under the terms of this Agreement; or

(v)

arise out of or result from any material breach of any representation and/or warranty made by the Distributor or the Fund in this Agreement or arise out of or result from any other material breach of this Agreement by the Distributor of the Fund;

as limited by and in accordance with the provisions of Sections 7.4(b) and 7.4(c) hereof.

(b) The Distributor shall not be liable under this indemnification provision with respect to any losses, claims, damages, liabilities 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 obligations and duties under this Agreement or to the Company or the Accounts, whichever is applicable.

(c) The Distributor 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 Distributor 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 any such service on any designated agent), but failure to notify the Distributor of any such claim shall not relieve the Distributor 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. In any case any such action is brought against the Indemnified Parties, the Distributor will be entitled to participate, at its own expense, in the defense thereof. The Sponsor also shall be entitled to assume the defense thereof, with counsel satisfactory to the party named in the action. After notice from the Distributor to such party of the Distributor’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 Distributor will not be liable to such party under this Agreement for any legal or other expenses subsequently incurred by each party independently in connection with the defense thereof other than reasonable costs of investigation.

(d) The Company agrees promptly to notify the Distributor of the commencement of any litigation or proceedings against it or any of its officers or directors in connection with the issuance or sale of the Variable Insurance Products or the operation of each account.

(d) termination by the Company by written notice to the Fund and the Sponsor with respect to any Portfolio in the event that such Portfolio 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 (in the event of such termination, the Company shall withdraw all assets allocable to the separate accounts from the Portfolio and shall reinvest such assets in a different investment medium, including, but not limited to, another Portfolio of the Fund); or

(e) termination by the Company by written notice to the Fund and the Sponsor with respect to any Portfolio in the event that such Portfolio fails to meet the diversification requirements as specified in Article VI hereof (in the event of such termination, the Company shall withdraw all assets allocable to the separate accounts from the Portfolio and shall reinvest such assets in a different investment medium, including, but not limited to, another Portfolio of the Fund); or

(f) termination by the Fund, the Sponsor, or the Distributor by written notice to the Company, if any of the Fund, the Sponsor, or the Distributor shall determine, in its sole judgment exercised in good faith, that the Company and/or its affiliated companies has suffered a material adverse change in its business, operations, or financial condition since the date of this Agreement or is the subject of material adverse publicity; or
