WHEREAS, Adviser has entered into an Investment Advisory Agreement dated as of the 10^th day of April, 2002 (“Advisory Agreement”) with the Fund, which is engaged in business as an open-end investment company registered under the Investment Company Act of 1940, as amended (“1940 Act”); and

WHEREAS, the Fund is authorized to issue shares of separate series of the Fund, including the series set forth in Schedule A (the “Portfolio”); and

WHEREAS, Subadviser is engaged principally in the business of rendering investment subadvisory management services and is registered as an investment adviser under the Investment Advisers Act of 1940, as amended (“Advisers Act”); and

WHEREAS, the Fund and Adviser desire to retain Subadviser as a subadviser to furnish certain investment advisory services to Adviser and the Portfolio and Subadviser is willing to furnish such services;

NOW, THEREFORE, in consideration of the premises and mutual promises herein set forth, the parties hereto agree as follows:

Appointment. (A) Adviser hereby appoints Subadviser as its investment subadviser with respect to the Portfolio for the period and on the terms set forth in this Agreement, and (B) Subadviser hereby accepts such appointment and agrees to render the services herein set forth, for the compensation herein provided.

II.

Additional Series. In the event that the Fund establishes one or more series of shares other than the Portfolio with respect to which Adviser desires to retain Subadviser to render investment advisory services hereunder, Adviser shall so notify Subadviser in writing, indicating the subadvisory fee to be payable with respect to the additional series

of shares. If Subadviser is willing to render such services on the terms provided for herein, it shall so notify Adviser in writing, whereupon such series shall become a Portfolio hereunder, and this Agreement shall be amended accordingly.

III.	Duties of Subadviser.

Subadviser is hereby authorized and directed and hereby agrees to (i) furnish continuously an investment program for the Portfolio, and (ii) determine from time to time what investments shall be purchased, sold or exchanged and what portion of the assets of the Portfolio shall be held uninvested. Subadviser shall perform these duties subject always to (1) the overall supervision of Adviser and the Board of Directors of the Fund (the “Board”), (2) the Fund’s Articles and By-laws (as defined below), as amended from time to time, (3) the stated investment objectives, policies and restrictions of the Portfolio as set forth in the Fund’s then current Registration Statement (as defined below), (4) any additional policies or guidelines established by Adviser or Board that have been furnished in writing to Subadviser, provided that Subadviser shall have acknowledged receipt of, and had reasonable time to implement, such policies and guidelines, (5) applicable provisions of law, including, without limitation, all applicable provisions of the 1940 Act and the rules and regulations thereunder, and (6) the Section 851(b)(2), Section 851(b)(3) and Section 817(h) of the Internal Revenue Code of 1986, as amended (the “Code”) applicable to “regulated investment companies” (as defined in Section 851 of the Code), as amended from time to time, based on Subadviser’s reasonable interpretation of the provisions and any information provided by the Portfolio’s administrator, custodian or other service providers. In accordance with Section VII, Subadviser shall arrange for the execution of all orders for the purchase and sale of securities and other investments for the Portfolio’s account and will exercise full discretion and act for the Portfolio in the same manner and with the same force and effect as the Portfolio might or could do with respect to such purchases, sales, or other transactions, as well as with respect to all other things necessary or incidental to the furtherance or conduct of such purchases, sales, or other transactions, including, without limitation, management of cash invested in a private investment company or short-term vehicle, or short-term securities used as collateral for derivatives positions in the Portfolio.

Subadviser may, as permitted by rule, regulation or position of the staff of the Securities and Exchange Commission, utilize the personnel of its affiliates including foreign affiliates in providing services under this Agreement, provided that Subadviser remains solely responsible for the provision of services under this Agreement.

Subadviser shall have no responsibility with respect to maintaining custody of the Portfolio’s assets. Subadviser shall affirm security transactions with central depositories and advise the custodian of the Portfolio (“Custodian”) or such depositories or agents as may be designated by Custodian and Adviser promptly

of each purchase and sale of a portfolio security, specifying the name of the issuer, the description and amount or number of shares of the security purchased, the market price, the commission and gross or net price, the trade date and settlement date and the identity of the effecting broker or dealer. At the request of Adviser, Subadviser shall from time to time provide Custodian and Adviser with evidence of authority of its personnel who are authorized to give instructions to Custodian.

Unless Adviser advises Subadviser in writing that the right to vote proxies has been expressly reserved to Adviser or the Fund or otherwise delegated to another party, Subadviser shall exercise voting rights incident to any securities held in the Portfolio without consultation with Adviser or Fund, provided that Subadviser will follow any written instructions received in a timely manner from Adviser or Fund with respect to voting as to particular issues. Subadviser shall further respond to all corporate action matters incident to the securities held in the Portfolio including, without limitation, proofs of claim in bankruptcy and class action cases and shelf registrations. Adviser agrees and acknowledges that Adviser shall be responsible for any regulatory filings, including filings made on Form N-PX, with respect to the Portfolio’s proxy voting.

Upon request of Custodian and/or Fund, Subadviser shall provide assistance in connection with the determination of the fair value of securities in the Portfolio for which market quotations are not readily available, it being understood that Subadviser shall have no liability to the Adviser or the Fund for any valuation it may provide to the Adviser. The Fund and Adviser acknowledge that the designated pricing agent, and not the Subadviser, is responsible for providing valuation of the assets in the Portfolio, and any additional information provided by Subadviser shall be supplemental information to assist the Fund and its pricing agent to meet the Fund’s fair valuation obligations.

In the performance of its duties hereunder, Subadviser is and shall be an independent contractor and, except in connection with its duties as set forth in this Section III or as expressly provided for herein or otherwise expressly provided or authorized, shall have no authority to act for or represent the Portfolio or the Fund in any way or otherwise be deemed to be an agent of the Portfolio, the Fund or Adviser.

The Subadviser shall have no responsibility under this Agreement with respect to the management of assets of the Portfolio other than the portion of the Portfolio’s assets with respect to which the Subadviser provides investment advice.

The Subadviser is prohibited from consulting with any other Subadviser of the Fund, if any, or the subadviser to any other investment company (or separate series of an investment company) managed by the Adviser concerning the Fund’s transactions in securities or other assets, except for the purpose of complying with the conditions of Rule 12d3-1 (a) and (b) under the 1940 Act.

IV.

Compensation. For the services provided pursuant to this Agreement, Subadviser shall receive a subadvisory fee as set forth in Schedule 1, attached hereto and incorporated herein by reference. The subadvisory fee shall be payable monthly in arrears to Subadviser on or before the 10th day of the next succeeding calendar month. If this Agreement becomes effective or terminates before the end of any month, the subadvisory fee for the period from the effective date to the end of such month or from the beginning of such month to the date of termination, as the case may be, shall be prorated according to the proration which such period bears to the full month in which such effectiveness or termination occurs.

Expenses. During the term of this Agreement, Subadviser will bear all expenses incurred by it in the performance of its duties hereunder, other than those expenses specifically assumed by the Fund hereunder. The Fund shall assume and shall pay all brokers’ and underwriting commissions chargeable to the Fund in connection with the securities transactions to which the Portfolio is a party. Subadviser shall not be responsible for other expenses of the Fund, including, without limitation, fees of the Fund’s independent public accountants, transfer agent, custodian, and other service providers who are not employees of Subadviser; brokerage commissions and other transaction-related expenses; tax reporting; taxes levied against the Fund or any of its property; and interest expenses of the Fund.

VI.	Duties of Adviser. Adviser has furnished Subadviser with copies of each of the following documents and will furnish to Subadviser at its principal office all future amendments and supplements to such documents, if any, as soon as practicable after such documents become available:

(1)

The Articles of Incorporation of the Fund, as filed with the State of Minnesota, as in effect on the date hereof and as amended from time to time (“Articles”);

(2)

The by-laws of the Fund as in effect on the date hereof and as amended from time to time (“By-Laws”); and

(3)

The Fund’s most recent Registration Statement under the 1940 Act and the Securities Act of 1933, as amended (the “1933 Act”) on Form N-1A, as filed with the Securities and Exchange Commission (“SEC”) relating to the Portfolio and its shares and all amendments thereto (“Registration Statement”), which includes the Portfolio’s most recent prospectus (the “Prospectus”) and statement of additional information;

Adviser shall furnish Subadviser with any further documents, materials or information that Subadviser may reasonably request to enable it to perform its duties pursuant to this Agreement. Until Adviser delivers to Subadviser any supplements or amendments to the Fund’s documents described above,

Subadviser shall be fully protected in relying on the most recent versions of such documents previously furnished to Subadviser.

VII.	Portfolio Transactions.

Subadviser agrees that, in executing portfolio transactions and selecting brokers or dealers, if any, it shall use its best efforts to seek on behalf of the Portfolio the best overall terms available. In assessing the best overall terms available for any transaction, Subadviser shall consider all factors it deems relevant, including the breadth of the market in, and the price of, the security, the financial condition and execution capability of the broker or dealer, and the reasonableness of the commission, if any, with respect to the specific transaction and on a continuing basis. In evaluating the best overall terms available, and in selecting the broker or dealer, if any, to execute a particular transaction, Subadviser may also consider the brokerage and research services (as those terms are defined in Section 28(e) of the Securities Exchange Act of 1934, as amended (“1934 Act”)) provided to Subadviser with respect to the Portfolio and/or other accounts over which Subadviser exercises investment discretion. Except to the extent prohibited or limited by law or regulation, Subadviser may, in its discretion, agree to pay a broker or dealer that furnishes such brokerage or research services a higher commission than that which might have been charged by another broker-dealer for effecting the same transactions, if Subadviser determines in good faith that such commission is reasonable in relation to the brokerage and research services provided by the broker or dealer, viewed in terms of either that particular transaction or the overall responsibilities of Subadviser with respect to the accounts as to which it exercises investment discretion (as such term is defined under Section 3(a)(35) of the 1934 Act). Subadviser shall, upon request from Adviser, provide such periodic and special reports describing any such brokerage and research services received and the incremental commissions, net price or other consideration to which they relate.

In no instance will portfolio securities be purchased from or sold to Subadviser, or any affiliated person thereof, except in accordance with the federal securities laws and the rules and regulations thereunder.

Subadviser may buy securities for the Portfolio at the same time it is selling such securities for another client account and may sell securities for the Portfolio at the time it is buying such securities for another client account. In such cases, subject to applicable legal and regulatory requirements, and in compliance with such procedures of the Fund as may be in effect from time to time, Subadviser may effectuate cross transactions between the Portfolio and such other account if it deems this to be advantageous. Adviser and the Fund acknowledge that, in the event of any such cross transaction, Subadviser may have a potential conflict of interest regarding the Portfolio and such other client account, and each of Adviser and Fund consents to any such cross transaction, provided that such cross

transaction is effected in compliance with the Portfolio’s Affiliated Trade Transactions Policy.

On occasions when Subadviser deems the purchase or sale of a security to be in the best interest of the Fund as well as other clients of Subadviser, Subadviser, 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. In such event, allocation of the securities so purchased or sold, as well as the expenses incurred in the transaction, will be made by Subadviser in the manner Subadviser considers to be equitable and consistent with its fiduciary obligations to the Fund and to its other clients.

VIII.

Ownership of Records. Subadviser shall maintain all books and records required to be maintained by Subadviser pursuant to the 1940 Act and the rules and regulations promulgated thereunder with respect to transactions on behalf of the Portfolio. In compliance with the requirements of Rule 31a-3 under the 1940 Act, Subadviser hereby agrees (A) that all records that it maintains for the Portfolio are the property of the Fund, (B) to preserve for the periods prescribed by Rule 31a-2 under the 1940 Act any records that it maintains for the Fund and that are required to be maintained by Rule 31a-1 under the 1940 Act, and (C) to surrender promptly to the Fund any records that it maintains for the Fund upon request by the Fund; provided, however, Subadviser may retain copies of such documents.

IX.	Reports and Meetings.

Subadviser shall furnish to the Board or Adviser, or both, as appropriate, such information, reports, evaluations, analyses and opinions as are required by law or that the Board or Adviser, as appropriate, may reasonably require, including, without limitation: compliance reporting and certification with respect to:

Affiliated Brokerage Transactions

Affiliated Underwritings

Subadviser shall make available in person to the Board and to Adviser personnel of Subadviser, as the Board or Adviser may reasonably request, to review the investments and the investment program of the Portfolio and the services provided by Subadviser hereunder.

X.	Services to Other Clients. Nothing contained in this Agreement shall limit or restrict (i) the freedom of Subadviser, or any affiliated person thereof, to render investment

management and corporate administrative services to other investment companies, to act as investment manager or investment counselor to other persons, firms, or corporations, or to engage in any other business activities, or (ii) the right of any director, officer, or employee of 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. Fund and Adviser understand that Subadviser, its affiliates and its agents perform investment advisory and management services for various clients. Fund and Adviser agree that Subadviser may give advice and take action in the performance of its duties with respect to any of its other clients which may differ from advice given or the timing or nature of action taken with respect to the Portfolio. Nothing in this Agreement shall be deemed to require Subadviser, its principals, affiliates, agents or employees to purchase or sell for the Portfolio any security which it or they may purchase or sell for its or their own account or for the account of any other client.

XI.

Subadviser’s Use of the Services of Others. Subadviser may, at its cost, employ, retain, or otherwise avail itself of the services or facilities of other persons or organizations for the purpose of providing Subadviser or the Fund or Portfolio, as appropriate, with such statistical and other factual information, such advice regarding economic factors and trends, such advice as to occasional transactions in specific securities, or such other information, advice, or assistance as Subadviser may deem necessary, appropriate, or convenient for the discharge of its obligations hereunder or otherwise helpful to the Fund or the Portfolio, as appropriate, or in the discharge of Subadviser’s overall responsibilities with respect to the other accounts that it serves as investment manager or counselor.

XII.

For purposes of this Agreement, “Related Persons” of a party are its officers, directors, and employees, and any person performing executive, administrative, trading, or other functions for the Fund, the Portfolio (at the direction or request of that party) or the party in connection with the party’s discharge of its obligations undertaken or reasonably assumed with respect to this Agreement. Neither Subadviser nor any of its Related Persons shall be liable for (i) any error of judgment or mistake of law or for any loss suffered by the Fund or Portfolio or (ii) any error of fact or mistake of law contained in any report or data provided by Subadviser, except for any error, mistake or loss resulting from willful misfeasance, bad faith, or gross negligence in the performance by Subadviser or such Related Person of Subadviser’s duties on behalf of the Fund or Portfolio or from reckless disregard by Subadviser or any such Related Person of the duties of Subadviser pursuant to this Agreement (each of which is referred to as a “Culpable Act”).

Notwithstanding the foregoing, any stated limitations on liability shall not relieve Subadviser from any responsibility or liability Subadviser may have under state or federal statutes or from responsibility or liability for errors by Subadviser in connection with the execution of trade orders.

Subadviser shall indemnify Adviser, the Fund and their respective Related Persons and hold them harmless from and against any and all actions, suits or claims whether

Schedule A

Thrivent Partner Healthcare Portfolio

Schedule 1

Dated September 8, 2017

Subadvisory Fee

Thrivent Partner Healthcare Portfolio

Compensation pursuant to Section IV of this Agreement shall be payable monthly in arrears and calculated in accordance with the following schedule applied to aggregate average daily net assets in the Thrivent Partner Healthcare Portfolio that are subject to the Subadviser’s investment discretion*:


Average Daily Net Assets**	Rate

First $50 million		0.500	%
Next $200 million		0.475	%
Next $250 million		0.450	%
Over $500 million		0.425	%

* For the avoidance of doubt, the assets that are subject to the Subadviser’s investment discretion shall include cash invested in a private investment company or short-term vehicle, or short-term securities used as collateral for derivatives positions in the Portfolio.

**When average daily net assets exceed the first breakpoint, multiple rates will apply, resulting in a blended rate, e.g., if average daily net assets are $75 million, a rate of 0.500% would apply to $50 million and a rate of .475% would apply to $25 million.
