Exhibit 99(d)(50)

SUB-ADVISORY AGREEMENT

THIS SUB-ADVISORY AGREEMENT (“Agreement”) is made among GUIDESTONE FUNDS, a Delaware business trust (“Trust”), and GUIDESTONE CAPITAL MANAGEMENT, LLC (“Adviser”), a limited liability company organized under the laws of the State of Texas, and XXXXXX XXXX EQUITY MANAGEMENT, INC., a registered investment adviser organized under the laws of the State of New Jersey (“Sub-Adviser”).

WHEREAS, the Adviser has entered into an Investment Advisory Agreement (“Management Agreement”) with the Trust, an open-end management investment company registered under the Investment Company Act of 1940, as amended (“1940 Act”); and

WHEREAS, the Small Cap Equity Fund (“Fund”) is a series of the Trust; and

WHEREAS, under the Management Agreement, the Adviser has agreed to provide certain investment advisory services to the Fund; and

WHEREAS, the Adviser is authorized under the Management Agreement to delegate certain of its investment advisory responsibilities to one or more persons or companies; and

WHEREAS, the Board of Trustees of the Trust (“Board”) and the Adviser desire that the Adviser retain the Sub-Adviser to render investment advisory services for the portion of the Fund’s assets allocated to the Sub-Adviser, as determined from time to time by the Adviser, in the manner and on the terms hereinafter set forth; and

WHEREAS, the Sub-Adviser is willing to furnish such services to the Adviser and the Fund;

NOW, THEREFORE, in consideration of the premises and mutual covenants herein contained, the Trust, the Adviser and the Sub-Adviser agree as follows:

1. Appointment. The Adviser and the Trust hereby appoint and employ the Sub-Adviser as a discretionary investment manager, on the terms and conditions set forth herein, of those assets of the Fund which the Adviser determines to assign to the Sub-Adviser (those assets being referred to as the “Fund Account”). The Adviser may from time to time make additions to and withdrawals, including but not limited to cash and cash equivalents, from the Fund Account, subject to verbal notification and subsequent written notification to the Sub-Adviser. The Sub-Adviser will be an independent contractor and will have no authority to act for or represent the Trust or the Adviser in any way or otherwise be deemed an agent of the Trust or the Adviser except as expressly authorized in this Agreement or another writing by the Trust, the Adviser and the Sub-Adviser.

2. Acceptance of Appointment. The Sub-Adviser accepts that appointment and agrees to render the services herein set forth, for the compensation herein provided.

3. Duties as Sub-Adviser.

(a) Subject to the supervision and direction of the Board and of the Adviser, including all written guidelines, policies and procedures adopted by the Trust or the Adviser that are provided to the

Sub-Adviser, the Sub-Adviser will: (i) provide a continuous investment program with respect to the Fund Account; (ii) determine from time to time what investments in the Fund Account will be purchased, retained or sold by the Fund; and (iii) be responsible for placing purchase and sell orders for investments and for other related transactions with respect to the Fund Account. The Sub-Adviser will provide services under this Agreement in accordance with the Fund’s investment objective, policies and restrictions and the description of its investment strategy and style, all as stated in the Trust’s registration statement under the 1940 Act, and any amendments or supplements thereto (“Registration Statement”), which the Adviser shall provide to the Sub-Adviser in writing. The Sub-Adviser is authorized on behalf of the Fund Account to enter into and execute any documents required to effect transactions with respect to the Fund Account, provided that such transactions are in accord with the Registration Statement and with all written guidelines, policies and procedures adopted by the Trust or the Adviser that are provided to the Sub-Adviser.

(b) In accordance with the Fund’s investment policies described in the Registration Statement, the Sub-Adviser is responsible for avoiding investment of Fund Account assets in the securities issued by any company that is publicly recognized, as determined by GuideStone Financial Resources of the Southern Baptist Convention (“GuideStone Financial Resources”), as being in the alcohol, tobacco, gambling, pornography or abortion industries, or any company whose products, services or activities are publicly recognized, as determined by GuideStone Financial Resources, as being incompatible with the moral and ethical posture of GuideStone Financial Resources. The Adviser shall provide in writing to the Sub-Adviser a list of such prohibited companies, which the Adviser in its sole discretion will amend or supplement from time to time. The Adviser will provide the Sub-Adviser with such amendments or supplements on a timely basis, and any such changes shall become effective once they have been received by the Sub-Adviser. Unless instructed by the Adviser to the contrary, the Sub-Adviser will have a reasonable amount of time to divest of any existing portfolio holdings in any new prohibited company or come into compliance with any other restriction related thereto. If the Sub-Adviser has a question about whether any proposed transaction with respect to the Fund Account would be in compliance with such investment policies, it may consult with the Adviser during normal business hours, and the Adviser will provide instructions upon which the Sub-Adviser may rely in purchasing and selling securities for the Fund Account.

(c) The Sub-Adviser will select brokers and dealers to effect all portfolio transactions for the Fund Account subject to the conditions set forth herein. The Sub-Adviser will place all necessary orders with brokers, dealers or issuers, and will negotiate brokerage commissions, if applicable. The Sub-Adviser agrees that, in placing orders with brokers, it will seek to obtain the best net result in terms of price and execution, considering all of the circumstances, and shall maintain records adequate to demonstrate compliance with this requirement; provided that, on behalf of the Fund, and in compliance with Section 28(e) of the Securities Exchange Act of 1934, the Sub-Adviser may, in its discretion, use brokers (including brokers that may be affiliates of the Sub-Adviser to the extent permitted by Section 3(d) hereof) who provide the Sub-Adviser with research, analysis, advice and similar services to execute portfolio transactions, and the Sub-Adviser may pay to those brokers in return for brokerage and research services a higher commission than may be charged by other brokers, subject to the Sub-Adviser’s determining in good faith that such commission is reasonable in terms either of the particular transaction or of the overall responsibility of the Sub-Adviser to the Fund and its other clients and that the total commissions paid by the Fund will be reasonable in relation to the benefits to the Fund over the long term. Subject to seeking best execution, the Board or the Adviser may direct the Sub-Adviser to effect transactions in portfolio securities through broker-dealers in a manner that will help generate

resources to pay the costs of certain expenses that the Trust is required to pay or for which the Trust is required to arrange payment. The Sub-Adviser agrees to provide the Adviser with reports or other information regarding brokerage and benefits received therefrom, upon the Adviser’s reasonable request. In no instance will portfolio securities or other assets be purchased from or sold to the Sub-Adviser, its affiliated persons, any other investment sub-adviser that serves as sub-adviser to one or more series of the Trust, or any affiliated person thereof, except in accordance with the 1940 Act, the Investment Advisers Act of 1940, as amended (“Advisers Act”), and the rules under each, and all other federal and state laws or regulations applicable to the Trust and the Fund, or in accordance with an order of exemption received from the United States Securities and Exchange Commission (“SEC”). On occasions when the Sub-Adviser deems the purchase or sale of a security to be in the best interest of the Fund as well as other accounts advised by the Sub-Adviser, the Sub-Adviser, to the extent permitted by applicable laws and regulations, may, but shall be under no obligation to, aggregate the securities to be purchased or sold to attempt to obtain a more favorable price or lower brokerage commissions and efficient execution. Whenever the Sub-Adviser simultaneously places orders to purchase or sell the same security on behalf of the Fund Account and one or more other accounts advised by the Sub-Adviser, the orders will be allocated as to price and amount among all such accounts in a manner the Sub-Adviser believes to be equitable over time and consistent with its fiduciary obligations to each account.

(d) Except as permitted by law or an exemptive order or rule of the SEC, and the Trust’s policies and procedures adopted thereunder, the Sub-Adviser agrees that it will not execute without the prior written approval of the Adviser any portfolio transactions for the Fund Account with a broker or dealer which is (i) an affiliated person of the Trust, the Adviser or any sub-adviser for any series of the Trust; (ii) a principal underwriter of the Trust’s shares; or (iii) an affiliated person of such an affiliated person or principal underwriter. The Adviser agrees that it will provide the Sub-Adviser with a written list of such brokers and dealers and will, from time to time, update such list as necessary. The Sub-Adviser agrees that it will provide the Adviser with a written list of brokers and dealers that are affiliates of the Sub-Adviser and will, from time to time, update such list as necessary.

(e) In furnishing services hereunder, to the extent prohibited under, or necessary to comply with, the 1940 Act, the Sub-Adviser will not consult with any other sub-adviser to the Fund, any other series of the Trust, or any other investment company under common control with the Trust concerning transactions of the Fund in securities or other assets. For the avoidance of doubt, the foregoing restriction will not be deemed to prohibit the Sub-Adviser from consulting with: (i) any of its affiliated persons concerning transactions in securities or other assets; (ii) any of the other covered sub-advisers concerning compliance with paragraphs (a) and (b) of Rule 12d3-1; and (iii) a successor sub-adviser of the Fund in order to effect an orderly transition of sub-advisory duties so long as such consultations do not require the Sub-Adviser to provide specific recommendations regarding the purchase or sale of securities or concern transactions prohibited by Section 17(a) of the 1940 Act.

(f) The Sub-Adviser will maintain all books and records required to be maintained pursuant to the 1940 Act and the rules and regulations promulgated thereunder with respect to actions by the Sub-Adviser on behalf of the Fund, and will furnish the Board, the Adviser or the Fund’s administrator (“Administrator”) with such periodic and special reports as any of them reasonably may request. In compliance with the requirements of Rule 31a-3 under the 1940 Act, the Sub-Adviser hereby agrees

that all records that it maintains for the Fund are the property of the Trust, agrees to preserve for the periods prescribed by Rule 31a-2 under the 1940 Act any records that it maintains for the Trust and that are required to be maintained by Rule 31a-1 under the 1940 Act, and further agrees to surrender promptly to the Trust a complete set of any records that it maintains for the Fund upon request by the Trust.

(g) All transactions will be consummated by payment to or delivery by the custodian designated by the Trust (the “Custodian”), or such depositories or agents as may be designated by the Custodian in writing, of all cash and/or securities due to or from the Fund Account, and the Sub-Adviser shall not have possession or custody thereof. The Sub-Adviser shall advise the Custodian and confirm in writing to the Trust, to the Adviser and any other designated agent of the Fund, including the Administrator, all investment orders for the Fund Account placed by it with brokers and dealers at the time and in the manner set forth in Rule 31a-1 under the 1940 Act. For purposes of the foregoing sentence, communication via electronic means will be acceptable as agreed to in writing from time to time by the Adviser. The Trust shall issue to the Custodian such instructions as may be appropriate in connection with the settlement of any transaction initiated by the Sub-Adviser. The Trust shall be responsible for all custodial arrangements and the payment of all custodial charges and fees, and, the Sub-Adviser shall have no responsibility or liability with respect to custodial arrangements or the acts, omissions or other conduct of the Custodian, other than acts or omissions arising in reliance on instructions of the Sub-Adviser given within the scope of its duties hereunder to the Custodian, and except that it shall be the responsibility of the Sub-Adviser to notify the Adviser if the Custodian fails to confirm in writing proper execution of such instructions.

(h) The Sub-Adviser agrees to provide, at such times as shall be reasonably requested by the Board or the Adviser, the analysis and reports specified on Schedule A attached hereto, including without limitation monthly reports setting forth the investment performance of the Fund Account. The Sub-Adviser also agrees to make available to the Board and Adviser any economic, statistical and investment services that the Sub-Adviser normally makes available to its institutional or other customers.

(i) In accordance with procedures adopted by the Board, as amended from time to time, the Sub-Adviser will assist the Administrator and/or the Fund in determining the fair valuation of all portfolio securities held in the Fund Account and will use its reasonable efforts to arrange for the provision of valuation information or a price(s) for each portfolio security held in the Fund Account for which the Administrator does not obtain prices in the ordinary course of business from an automated pricing service. The Sub-Adviser shall promptly notify the Adviser if, for any reason, the Sub-Adviser believes that the price of any security or other investment in the Fund Account may not accurately reflect the value thereof. The Sub-Adviser will maintain adequate records with respect to securities valuation information provided hereunder and shall provide such information to the Adviser upon request, with such records being deemed Fund records.

(j) The Sub-Adviser shall provide reasonable assistance to provide information within its possession and control as needed in the preparation of (but not pay for) all periodic reports by the Trust or the Fund to shareholders of the Fund and all reports and filings required to maintain the registration and qualification of the Fund, or to meet other regulatory or tax requirements applicable to the Fund, under federal and state securities and tax laws. Upon the request of the Trust or the Adviser, the Sub-Adviser shall review draft reports to shareholders, Registration Statements or portions thereof that

relate to the Fund Account or the Sub-Adviser and other documents provided to the Sub-Adviser that relate to the Fund Account or the Sub-Adviser, provide comments on such drafts on a timely basis, and provide certifications or sub-certifications on a timely basis as to the accuracy of the Sub-Adviser’s information contained in such reports or other documents. The Sub-Adviser will prepare and cause to be filed in a timely manner Form 13F and, if required, Schedule 13G with respect to securities held for the Fund Account.

(k) As reasonably requested by the Trust on behalf of the Trust’s officers and in accordance with the scope of the Sub-Adviser’s obligations and responsibilities contained in this Agreement (i.e., with respect to the Fund Account and the Sub-Adviser’s provision of portfolio management services hereunder), the Sub-Adviser will provide reasonable assistance to the Trust in connection with the Trust’s compliance with the Xxxxxxxx-Xxxxx Act and the rules and regulations promulgated by the SEC thereunder, and Rule 38a-1 of the 1940 Act. Specifically, the Sub-Adviser agrees to (a) certify periodically, upon the reasonable request of the Trust, that with respect to the Fund Account and the Sub-Adviser’s provision of portfolio management services hereunder, it is in compliance with all applicable “federal securities laws”, as required by Rule 38a-l under the 1940 Act, and Rule 206(4)-7 under the Advisers Act; (b) upon request and reasonable prior notice, cooperate with third-party audits arranged by the Trust to evaluate the effectiveness of the Trust’s compliance controls by providing information that will reasonably assist the third party to assess the effectiveness of the Sub-Adviser’s controls; (c) upon request and reasonable prior notice, provide the Trust’s chief compliance officer with direct access to its chief compliance officer (or his/her designee); (d) upon request, provide the Trust’s chief compliance officer with periodic reports in the form and substance agreed to by the parties; and (e) promptly provide notice of any material compliance matters that relate to, or could reasonably be expected to have an impact on, the Fund Account, Fund, Trust or the performance of the Sub-Adviser’s duties under this Agreement.

(l) The Sub-Adviser will not be responsible for making any class action filings, including bankruptcies, on behalf of the Fund Account. The Sub-Adviser shall promptly provide the Trust and the Adviser with any notice addressed to the Trust or the Fund that it receives regarding class action claims or any other legal matters involving any asset held in the Fund Account and shall reasonably cooperate with the Trust and the Adviser to provide information within its possession and control necessary for the Trust or the Adviser to pursue and/or participate in any such action.

4. Further Duties. In all matters relating to the performance of this Agreement, the Sub-Adviser will act in conformity with the provisions of the Trust’s Trust Instrument, By-Laws and Registration Statement of which it has received written notice, with all written guidelines, policies and procedures adopted by the Trust as applicable to the Fund Account that are provided to the Sub-Adviser in writing, and with the written instructions and written directions of the Board and the Adviser; and will comply with the requirements of (i) the 1940 Act and Advisers Act and the rules under each; (ii) the requirements of Subchapter M of the Internal Revenue Code of 1986, as amended, applicable to regulated investment companies; (iii) the Commodity Exchange Act, as amended, and the rules and regulations adopted thereunder from time to time; and (iv) all other federal and state laws and regulations applicable to the Trust and the Fund. The Adviser agrees to provide to the Sub-Adviser copies of the Trust’s Trust Instrument, By-Laws, Registration Statement, written guidelines, policies and procedures adopted by the Trust as applicable to the Fund Account, written instructions and directions of the Board and the Adviser, and any amendments or supplements to any of these materials as soon as practicable after such materials become available.

5. Proxies. Unless the Adviser gives written instructions to the contrary, provided the Custodian has timely forwarded the relevant proxy materials, the Sub-Adviser will vote in accordance with its policies and procedures all proxies solicited by or with respect to the issuers of securities in which assets of the Fund Account may be invested from time to time. The Adviser shall instruct the Custodian to forward or cause to be forwarded to the Sub-Adviser (or its designated agent) all relevant proxy solicitation materials.

6. Expenses. During the term of this Agreement, the Sub-Adviser will bear all expenses incurred by it in connection with its services under this Agreement other than the cost of securities purchased for the Fund Account and any expenses attributable to the positions in the Fund Account and the purchase or sale of any security for the Fund Account (including, without limitation, brokerage commissions, transactional fees and taxes, if any). The Trust and the Fund shall be responsible for all of their respective expenses, including without limitation custodial and administrator fees.

7. Compensation. The compensation of the Sub-Adviser for its services under this Agreement shall be calculated daily and paid monthly by the Trust, and not the Adviser, in accordance with the attached Schedule B. The Sub-Adviser shall not be responsible for any expenses incurred by the Adviser, the Fund or the Trust. If this Agreement becomes effective or terminates before the end of any month, the fee for the period from the effective date to the end of the month or from the beginning of such month to the date of termination, as the case may be, shall be pro-rated according to the proportion that such period bears to the full month in which such effectiveness or termination occurs. The Adviser shall be responsible for computing the fee based upon a percentage of the average daily net asset value of the assets of the Fund Account.

8. Limitation of Liability. The Sub-Adviser shall not be liable for any loss due solely to a mistake of investment judgment, but the Sub-Adviser shall be liable for any loss which is incurred by reason of an act or omission of its employee, partner, director or affiliate, if such act or omission involves willful misfeasance, bad faith or gross negligence, or breach of its duties or obligations hereunder, whether express or implied. Nothing in this paragraph shall be deemed a limitation or waiver of any obligation or duty that may not by law be limited or waived.

9. Indemnification.

(a) The Adviser shall indemnify the Sub-Adviser or any of its directors, officers, employees or affiliates for all losses, damages, liabilities, costs and expenses (including reasonable legal fees) (“Losses”) incurred by the Sub-Adviser by reason of or arising out of any act or omission by the Adviser under this Agreement, if such act or omission involves the gross negligence, willful misfeasance, bad faith or breach of fiduciary duty of the Adviser, or any breach of warranty, representation or agreement hereunder, except to the extent that such Losses arise as a result of the gross negligence, willful misfeasance or bad faith of the Sub-Adviser or the Sub-Adviser’s breach of fiduciary duty to the Adviser.

faith or breach of fiduciary duty of the Trust, or any breach of warranty, representation or agreement hereunder, except to the extent that such Losses arise as a result of the gross negligence, willful misfeasance or bad faith of the Sub-Adviser or the Sub-Adviser’s breach of fiduciary duty to the Trust.

(d) The Sub-Adviser shall indemnify the Trust or any of its trustees, officers, employees or affiliates for all losses, damages, liabilities, costs and expenses (including reasonable legal fees) (“Losses”) incurred by the Trust by reason of or arising out of any act or omission by the Sub-Adviser under this Agreement if such act or omission involves the gross negligence, willful misfeasance, bad faith or breach of fiduciary duty of the Sub-Adviser, or any breach of warranty, representation or agreement hereunder, except to the extent that such Losses arise as a result of the gross negligence, willful misfeasance or bad faith of the Trust or the Trust’s breach of fiduciary duty to the Fund.
