INVESTMENT SUBADVISORY AGREEMENT

Milliman Financial Risk Management LLC

This Agreement, entered into as of November 10, 2014 by and between Transamerica Asset Management, Inc., a Florida corporation (referred to herein as “TAM”) and Milliman Financial Risk Management LLC, a Delaware limited liability company (referred to herein as the “Subadviser”).

TAM is the investment adviser to Transamerica Series Trust (the “Trust”), an open-end investment company registered under the Investment Company Act of 1940 (collectively with the rules and regulations promulgated thereunder and any exemptive orders thereunder, the “1940 Act”). TAM wishes to engage the Subadviser to provide certain investment advisory services to each series of the Trust listed on Schedule A hereto (collectively, the “Funds” and each, a “Fund”). The Subadviser desires to furnish services for the Trust and to perform the functions assigned to it under this Agreement for the considerations provided. Accordingly, the parties have agreed as follows:

1. Appointment. In accordance with the Investment Advisory Agreement between the Trust and TAM (the “Advisory Agreement”), TAM hereby appoints the Subadviser to act as subadviser with respect to the Funds for the period and on the terms set forth in this Agreement. The Subadviser accepts such appointment and agrees to render or cause to be rendered the services set forth for the compensation herein specified.

2. Subadvisory Services. In its capacity as subadviser to the Funds, the Subadviser shall have the following responsibilities:

(a) Subject to the supervision of the Trust’s Board of Trustees (the “Board”) and TAM, the Subadviser shall regularly provide the Funds with respect to such portion of each Fund’s assets as shall be allocated to the Subadviser by TAM from time to time (the “Allocated Assets”) with investment research, advice, management and supervision and shall furnish a continuous investment program for the Allocated Assets consistent with the Funds’ investment objectives, policies and restrictions, as stated in the Funds’ current Prospectus and Statement of Additional Information, and subject to such other restrictions and limitations as directed by the officers of TAM or the Trust by notice in writing to the Subadviser. The Subadviser shall, with respect to the Allocated Assets, determine from time to time what securities and other investments and instruments will be purchased, retained, sold or exchanged by the Funds and what portion of the Allocated Assets will be held in the various securities and other investments in which the Funds invest, and shall implement those decisions (including the negotiation and execution of investment documentation and agreements, including, without limitation, swap, futures, options and other agreements with counterparties, on the Funds’ behalf as the Subadviser deems appropriate from time to time in order to carry out its responsibilities hereunder, provided the Subadviser provides TAM prompt notice of any new

investment agreements and any material amendments to existing investment agreements and the opportunity for legal review), all subject to the provisions of the Trust’s Declaration of Trust and By-Laws (collectively, the “Governing Documents”), the 1940 Act and the applicable rules and regulations promulgated thereunder by the Securities and Exchange Commission (the “SEC”), interpretive guidance issued thereunder by the SEC staff and any other applicable federal and state law, as well as the investment objectives, policies and restrictions of the Funds referred to above, any written instructions and directions of the Board or TAM provided to the Subadviser from time to time, and any other specific policies adopted by the Board and disclosed to the Subadviser. The Subadviser’s responsibility for providing investment research, advice, management and supervision to the Funds is limited to that discrete portion of each Fund represented by the Allocated Assets and the Subadviser is prohibited from directly or indirectly consulting with any other subadviser for a portion of the Funds’ assets concerning Fund transactions in securities or other assets. The Subadviser is authorized to give instructions with respect to the Allocated Assets to the custodian of the Funds as to deliveries of securities and other investments and payments of cash for the account of the Funds. Subject to applicable provisions of the 1940 Act, the investment program to be provided hereunder may entail the investment of all or substantially all of the assets of the Funds in one or more investment companies.

(b) The Subadviser will place orders pursuant to its investment determinations for the Funds either directly with the issuer or with any broker or dealer, foreign currency dealer, futures commission merchant or others selected by it. In connection with the selection of such brokers or dealers and the placing of such orders, subject to applicable law, brokers or dealers may be selected who also provide brokerage and research services (as those terms are defined in Section 28(e) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) to the Funds and/or the other accounts over which the Subadviser or its affiliates exercise investment discretion. The Subadviser is authorized to pay a broker or dealer who provides such brokerage and research services a commission for executing a portfolio transaction for the Funds which is in excess of the amount of commission another broker or dealer would have charged for effecting that transaction if the Subadviser determines in good faith that such amount of commission is reasonable in relation to the value of the brokerage and research services provided by such broker or dealer. This determination may be viewed in terms of either that particular transaction or the overall responsibilities which the Subadviser and its affiliates have with respect to accounts over which they exercise investment discretion. The Board may adopt policies and procedures that modify and restrict the Subadviser’s authority regarding the execution of the Funds’ portfolio transactions provided herein.

(c) Each Fund hereby authorizes any entity or person associated with the Subadviser which is a member of a national securities exchange to effect any transaction on the exchange for the account of such Fund which is permitted by Section 11(a) of the Exchange Act and Rule 11a2-2(T) thereunder, and such Fund hereby consents to the retention of compensation for such transactions in accordance with Rule 11a2-2(T)(a)(2)(iv).

- 2 -

Notwithstanding the foregoing, the Subadviser agrees that it will not deal with itself, or with Trustees of the Trust or any principal underwriter of the Funds, as principals or agents in making purchases or sales of securities or other property for the account of the Funds, nor will it purchase any securities from an underwriting or selling group in which the Subadviser or its affiliates is participating, or arrange for purchases and sales of securities between a Fund and another account advised by the Subadviser or its affiliates, except in each case as permitted by the 1940 Act and in accordance with such policies and procedures as may be adopted by the Funds from time to time, and will comply with all other provisions of the Governing Documents and the Funds’ then-current Prospectus and Statement of Additional Information relative to the Subadviser and its directors and officers.

(d) Unless TAM advises the Subadviser in writing that the right to vote proxies has been expressly reserved to TAM or the Trust or otherwise delegated to another party, the Subadviser shall exercise voting rights incident to any security purchased with, or comprising a portion of, the Allocated Assets, in accordance with the Subadviser’s proxy voting policies and procedures without consultation with TAM or the Funds. The Subadviser agrees to furnish a copy of its proxy voting policies and procedures, and any amendments thereto, to TAM. The Subadviser agrees to provide TAM in a timely manner with all information relating to the Subadviser necessary for preparation of the Funds’ proxy statements or other required mailings, as may be needed from time to time.

(e) The Subadviser will monitor the security valuations of the Allocated Assets. If the Subadviser believes that the Funds’ carrying value for a security does not fairly represent the price that could be obtained for the security in a current market transaction, the Subadviser will notify TAM promptly. In addition, the Subadviser will be available to consult with TAM in the event of a pricing problem and to participate in the Trust’s Valuation Committee meetings.

(f) The Subadviser represents and warrants that none of the information or work product utilized by it in connection with its provision of subadvisory services pursuant to this Agreement infringes on any third party patent, copyright, trade secret, trademark, or other intellectual property rights of any kind, without limitation, and that there is no actual or threatened claim or lawsuit by any third party for infringement of those rights. Subadviser further represents and warrants that it shall promptly inform TAM if, after the effective date, Subadviser receives an actual or threatened claim or lawsuit by any third party based on a violation of such rights.

3. Activities of the Subadviser. Nothing in this Agreement shall limit or restrict the right of any director, officer, or employee of the Subadviser to engage in any other business or to devote his or her time and attention in part to the management or other aspects of any other business, whether of a similar nature or a dissimilar nature, nor to limit or restrict the right of the Subadviser to engage in any other business or to render services of any kind, including investment advisory and management services, to any other fund, firm, individual or association. If the purchase or sale of securities for the Funds and one or more other accounts of the Subadviser is

- 3 -

considered at or about the same time, transactions in such securities will be allocated among the accounts in a manner deemed equitable by the Subadviser. Such transactions may be combined, in accordance with applicable laws and regulations, and consistent with the Subadviser’s policies and procedures as presented to the Board from time to time.

4. Allocation of Charges and Expenses. During the term of this Agreement, each Fund will bear all expenses not expressly assumed by TAM or the Subadviser incurred in the operation of such Fund and the offering of its shares. Without limiting the generality of the foregoing:

(a) Each Fund shall pay its allocable share of (i) fees payable to TAM pursuant to the Advisory Agreement; (ii) the cost (including brokerage commissions, if any) incurred in connection with purchases and sales of such Fund’s portfolio securities; (iii) expenses of organizing such Fund; (iv) filing fees and expenses relating to registering and qualifying and maintaining the registration and qualification of such Fund’s shares for sale under federal and state securities laws; (v) the compensation, fees and reimbursements paid to the Trust’s non-interested Trustees; (vi) custodian and transfer agent fees; (vii) legal and accounting expenses allocable to such Fund, including costs for local representation in the Trust’s jurisdiction of organization and fees and expenses of special counsel, if any, for the independent Trustees; (viii) all federal, state and local tax (including stamp, excise, income and franchise taxes) and the preparation and filing of all returns and reports in connection therewith; (ix) cost of certificates, if any, and delivery to purchasers; (x) expenses of preparing and filing reports with federal and state regulatory authorities; (xi) expenses of shareholders’ meetings and of preparing, printing and distributing proxy statements (unless otherwise agreed to by the Trust and TAM); (xii) costs of any liability, uncollectible items of deposit and other insurance or fidelity bonds; (xiii) any costs, expenses or losses arising out of any liability of, or claim for damage or other relief asserted against, the Trust for violation of any law; (xiv) expenses of preparing, typesetting and printing prospectuses and supplements thereto for existing shareholders and of reports and statements to shareholders; (xv) fees and expenses in connection with membership in investment company organizations and 12b-1 fees; and (xvi) any extraordinary expenses incurred by the Trust on behalf of such Fund.

5. Obligation to Provide Information. Each party’s obligation to provide information shall be as follows:

(a) TAM shall cause the Subadviser to be kept fully informed at all times with regard to the securities owned by each Fund, its funds available, or to become available, for investment, and generally as to the condition of each Fund’s affairs. TAM shall furnish the Subadviser with such other documents and information with regard to each Fund’s affairs as the Subadviser may from time to time reasonably request.

(b) The Subadviser, at its expense, shall supply the Board, the officers of the Trust and TAM with all information and reports reasonably required by them and reasonably available to the Subadviser relating to the services provided by the Subadviser hereunder, including such information the Funds’ Chief Compliance Officer reasonably believes necessary for compliance with Rule 38a-1 under the 1940 Act.

6. Compensation of the Subadviser. As compensation for the services performed by the Subadviser, TAM shall pay the Subadviser out of the advisory fee it receives with respect to each Fund, and only to the extent thereof, as promptly as possible after the last day of each month, a fee, computed daily at an annual rate set forth opposite each Fund’s name on Schedule A annexed hereto. The first payment of the fee shall be made as promptly as possible at the end of the month succeeding the effective date of this Agreement, and shall constitute a full payment of the fee due the Subadviser for all services prior to that date. If this Agreement is terminated as of any date not the last day of a month, such fee shall be paid as promptly as possible after such date of termination, shall be based on the average daily net assets of such Fund or, if less, the portion thereof comprising the Allocated Assets, in that period from the beginning of such month to such date of termination, and shall be prorated according to the ratio that the number of business days in such period bears to the number of business days in such month. The average daily net assets of each Fund, or portion thereof comprising the Allocated Assets, shall in all cases be based only on business days and be computed as of the time of the regular close of business of the New York Stock Exchange, or such other time as stated in such Fund’s then-current Prospectus or as may be determined by the Board.

7. Compensation of Trustees, Officers and Employees. No Trustee, officer or employee of the Trust or the Funds shall receive from the Trust or the Funds any salary or other compensation as such Trustee, officer or employee while he is at the same time a director, officer, or employee of the Subadviser or any affiliated company of the Subadviser, except as the Board may decide. This paragraph shall not apply to Trustees, executive committee members, consultants and other persons who are not regular members of the Subadviser’s or any affiliated company’s staff.

8. Term. This Agreement shall continue in effect with respect to each Fund, unless sooner terminated in accordance with its terms, for two years from its effective date, and shall continue in effect from year to year thereafter, provided such continuance is specifically approved at least annually by the vote of a majority of the Trustees who are not parties hereto or interested persons of any such party, cast in person at a meeting called for the purpose of voting on the approval of the terms of such renewal, and by either the Board or the affirmative vote of a majority of outstanding voting securities of such Fund.

9. Termination. This Agreement may be terminated with respect to each Fund at any time, without penalty, by the Board or by the shareholders of such Fund acting by vote of at least a majority of its outstanding voting securities. This Agreement may also be terminated by TAM

- 5 -

upon written notice to the Subadviser, without the payment of any penalty. The Subadviser may terminate the Agreement, without the payment of any penalty, only upon giving 90 days’ advance written notice to TAM. This Agreement shall terminate automatically in the event of its assignment by the Subadviser and shall not be assignable by TAM without the consent of the Subadviser. For the avoidance of doubt, it is understood that this Agreement may be amended, terminated or not renewed as to one or more Funds without affecting the other Funds hereunder.

10. Use of Name. If this Agreement is terminated with respect to a Fund and the Subadviser no longer serves as subadviser to such Fund, the Subadviser reserves the right to withdraw from the Trust the right to the use of its name with respect to that Fund, or any name misleadingly implying a continuing relationship between such Fund and the Subadviser or any of its affiliates.

11. Liability of the Subadviser. The Subadviser may rely on information reasonably believed by it to be accurate and reliable. The Subadviser assumes no responsibility under this Agreement other than to render the services called for hereunder, in good faith, and shall not be liable for any error of judgment or mistake of law, or for any loss arising out of any investment or for any act or omission in the execution of securities transactions for the Funds, provided that nothing in this Agreement shall protect the Subadviser against any liability to TAM or the Funds to which the Subadviser would otherwise be subject by reason of willful misconduct, bad faith, or gross negligence in the performance of its duties or by reason of its reckless disregard of its obligations and duties hereunder. As used in this Section 11, the term the “Subadviser” shall include any affiliates of the Subadviser performing services for the Trust or the Funds contemplated hereby and the partners, shareholders, directors, officers and employees of the Subadviser and such affiliates. Federal and state securities laws impose liabilities under certain circumstances on persons who act in good faith, and nothing in this Agreement shall in any way constitute a waiver or limitation of any rights that either party may have under any such laws.

12. Dispute Resolution. If any dispute occurs between the parties, they shall attempt in good faith to resolve the dispute by mediation. In such mediation, the parties thereto will choose a mutually acceptable mediator. If such mediation fails after a good-faith effort has occurred, only then may a party institute litigation. If a party files a lawsuit, and both a state and a federal court have subject matter jurisdiction over all of the claims to be filed, then the party shall file such suit in federal district court. Both parties agree to waive the right to a trial by jury. The execution of this agreement shall impose no personal liability on the directors, officers or employees of TAM, the Trust, or Milliman.

13. Meanings of Certain Terms. For the purposes of this Agreement, each Fund’s “net assets” shall be determined as provided in such Fund’s then-current Prospectus and Statement of Additional Information and the terms “assignment,” “interested person,” and “majority of the outstanding voting securities” shall have the meanings given to them by Section 2(a) of the 1940 Act, subject to such exemptions as may be granted by the SEC by any rule, regulation or order.

14. Amendments. No provision of this Agreement may be changed, waived, discharged or terminated orally with respect to a Fund, but only by an instrument in writing signed by the party against which enforcement of the change, waiver, discharge or termination is sought. No material amendment of the Agreement shall be effective with respect to a Fund until approved, if so required by the 1940 Act, by vote of the holders of a majority outstanding voting securities of such Fund. Schedule A hereto may be amended at any time to add additional series of the Trust as agreed by the Trust, TAM and the Subadviser.

15. Books and Records. The Subadviser agrees that it will keep records relating to its services hereunder in accordance with all applicable laws, and in compliance with the requirements of Rule 31a-3 under the 1940 Act, the Subadviser hereby agrees that any records that it maintains for the Funds are the property of the Funds, and further agrees to surrender promptly to each Fund any of such records upon such Fund’s request. The Subadviser further agrees to arrange for the preservation of the records required to be maintained by Rule 31a-1 under the 1940 Act for the periods prescribed by Rule 31a-2 under the 1940 Act.

16. Independent Contractor. In the performance of its duties hereunder, the Subadviser is and shall be an independent contractor and, unless otherwise expressly provided herein or otherwise authorized in writing, shall have no authority to act for or represent a Fund or TAM in any way or otherwise be deemed to be an agent of a Fund or TAM.

17. Miscellaneous. This Agreement embodies the entire agreement and understanding between the parties hereto, and supersedes all prior agreements and understandings relating to the subject matter hereof. Should any part of this Agreement be held or made invalid by a court decision, statute, rule or otherwise, the remainder of this Agreement shall not be affected thereby. This Agreement shall be binding on and shall inure to the benefit of the parties hereto and their respective successors.

18. Governing Law. This Agreement shall be construed and the provisions thereof interpreted under and in accordance with the laws of the State of Florida and the applicable provisions of the 1940 Act.

19. Interpretation. Nothing contained herein shall be deemed to require the Trust to take any action contrary to its Governing Documents, or any applicable statutory or regulatory requirement to which it is subject or by which it is bound, or to relieve or deprive the Board of its responsibility for and control of the conduct of the affairs of the Trust.
