AGREEMENT made this 22^nd day of February, 2018, between John Hancock Advisers, LLC, a Delaware limited liability company (the "Adviser"), and Deutsche Investment Management Americas Inc., a Delaware corporation (the "Subadviser"). In consideration of the mutual covenants contained herein, the parties agree as follows:

1. APPOINTMENT OF SUBADVISER

The Subadviser undertakes to act as investment subadviser to, and, subject to the supervision of the Trustees of John Hancock Investment Trust (the "Trust") and the terms of this Agreement, to manage the investment and reinvestment of the assets of the Portfolios specified in Appendix A to this Agreement as it shall be amended by the Adviser and the Subadviser from time to time (the "Portfolios"). The Subadviser will be an independent contractor and will have no authority to act for or represent the Trust or Adviser in any way except as expressly authorized in this Agreement or another writing by the Trust and Adviser.

2. SERVICES TO BE RENDERED BY THE SUBADVISER TO THE TRUST

a. Subject always to the direction and control of the Trustees of the Trust, the Subadviser will manage the investments and determine the composition of the assets of the Portfolios in accordance with the Portfolios' registration statement, as amended and provided to the Subadviser from time to time. In fulfilling its obligations to manage the investments and reinvestments of the assets of the Portfolios, the Subadviser will:

i. obtain and evaluate pertinent economic, statistical, financial and other information affecting the economy generally and individual companies or industries the securities of which are included in the Portfolios or are under consideration for inclusion in the Portfolios;

ii. formulate and implement a continuous investment program for each Portfolio consistent with the investment objectives and related investment policies for each such Portfolio as described in the Trust's registration statement, as amended and provided to the Subadviser from time to time. The Adviser shall notify the Subadviser in advance of any amendments thereto relating to the Portfolio; Further, failure of the Subadviser to meet the investment objectives of the Portfolio as described in the Trust’s registration statement will not constitute a breach of this Agreement.

iii. take whatever steps are necessary to implement these investment programs by the purchase and sale of securities including the placing of orders for such purchases and sales;

iv. regularly report to the Trustees of the Trust with respect to the implementation of these investment programs; and

v. provide assistance to the Trust’s Custodian regarding the fair value of securities held by the Portfolios for which market quotations are not readily available.

b. The Subadviser, at its expense, will furnish (i) all necessary investment and management facilities, including salaries of personnel required for it to execute its duties faithfully, and (ii) administrative facilities, including bookkeeping, clerical personnel and equipment necessary for the efficient conduct of the management of the investments of the Portfolios (excluding determination of net asset value and shareholder accounting services).

c. The Subadviser will select brokers, dealers, futures commission merchants and other counterparties to effect all transactions for the Portfolios, including without limitation, with respect to transactions in securities, derivatives, foreign currency exchange, commodities and/or any other investments.  The Subadviser will place all orders with brokers, dealers, counterparties or issuers, and will negotiate brokerage commissions, spreads and other financial and non-financial terms, as applicable.  The Subadviser will always seek the best possible price and execution in the circumstances in all transactions.  Subject to the foregoing, the Subadviser is directed at all times to seek to execute transactions for the Portfolios in accordance with its trading policies, as disclosed by the Subadviser to the Portfolio from time to time, but in all cases subject to policies and practices established by the Portfolio and described in the Trust’s registration statement.  Notwithstanding the foregoing, the Subadviser may pay a broker-dealer that provides research and brokerage services a higher spread or commission for a particular transaction than otherwise might have been charged by another broker-dealer to the extent permitted by Section 28(e) of the Securities Exchange Act of 1934 and by the Trust’s registration statement, if the Subadviser determines that the higher spread or commission is reasonable in relation to the value of the brokerage and research services that such broker-dealer provides, viewed in terms of either the particular transaction or the Subadviser’s overall responsibilities with respect to accounts managed by the Subadviser. The Subadviser may use for the benefit of the Subadviser’s other clients, or make available to companies affiliated with the Subadviser or to its directors for the benefit of its clients, any such brokerage and research services that the Subadviser obtains from brokers or dealers.

d. On occasions when the Subadviser deems the purchase or sale of a security to be in the best interest of the Portfolio as well as other clients of the Subadviser, the 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 the Subadviser in the manner the Subadviser considers to be the most equitable and consistent with its fiduciary obligations to the Portfolio and to its other clients.

e. Subject to applicable laws and regulations, including Rule 10f-3 under the Investment Company Act of 1940, Subadviser may purchase securities from an unaffiliated syndicate member in an underwriting in which an affiliated broker-dealer participates in the management activities of the syndicate.
