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 North American Funds (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. 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; 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 for purposes of enabling the Trust's Custodian to calculate net asset value. 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 investment affairs of the Portfolios (excluding determination of net asset value and shareholder accounting services). c. The Subadviser will select brokers and dealers to effect all transactions subject to the following conditions: The Subadviser will place all orders with brokers, dealers, or issuers, and will negotiate brokerage commissions if applicable. The Subadviser is directed at all times to seek to execute brokerage transactions for the Portfolios in accordance with such policies or practices as may be established by the Trustees and described in the Trust's registration statement as amended. The Subadviser may pay a broker-dealer which provides research and brokerage services a higher spread or commission for a particular transaction than otherwise might have been charged by another broker-dealer, 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. In accordance with Section 11(a) of the Securities Exchange Act of 1934, as amended, and Rule 11a-2-2(T) thereunder, and subject to any other applicable laws and regulations including Section 17(e) of the Investment Company Act of 1940 (the "Investment Company Act") and Rule 17e-1 thereunder, the Subadviser may engage its affiliates as broker-dealers to effect portfolio transactions in securities for the Portfolios. 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. The Subadviser will maintain all accounts, books and records with respect to the Portfolios as are required of an investment adviser of a registered investment company pursuant to the Investment Company Act and Investment Advisers Act of 1940 (the "Investment Advisers Act") and the rules thereunder. f. The Subadviser, including its Access Persons (as defined in subsection (e) of Rule 17j-1 under the Investment Company Act), agrees to observe and comply with Rule 17j-1 and its Code of Ethics (which shall comply in all material respects with Rule 17j-1, as the same may be amended from time to time). On a quarterly basis, the Subadviser will either (i) certify to the Adviser that the Subadviser and its Access Persons have complied with the Subadviser's Code of Ethics with respect to the Portfolio or (ii) identify any material violations which have occurred with respect to the Portfolio. In addition, the Subadviser will report at least annually to the Adviser concerning any other violations of the Subadviser's Code of Ethics which required significant remedial action and which were not previously reported. 3. COMPENSATION OF SUBADVISER The Adviser will pay the Subadviser with respect to each Portfolio the compensation specified in Appendix A to this Agreement. 4. LIABILITY OF SUBADVISER Neither the Subadviser nor any of its affiliates, officers, partners or employees, nor anyone who controls the Subadviser (or any of its affiliates, officers, partners or employees) within the meaning of Section 15 of the Securities Act of 1933 (the "1933 Act"), shall be liable to the Adviser or Trust for any loss suffered by the Adviser or Trust resulting from any error of judgment made in the good faith exercise of the Subadviser's investment discretion in connection with selecting Portfolio investments except for losses resulting from willful misfeasance, bad faith or gross negligence of, or from reckless disregard of, the duties of the Subadviser or any of its affiliates, partners or employees; and neither the Subadviser nor any of its affiliates, officers, partners or employees, nor anyone who controls the Subadviser (or any of its affiliates, officers, partners or employees) within the meaning of Section 15 of the 1933 Act, shall be liable to the Adviser or Trust for any loss suffered by the Adviser or Trust resulting from any other matters to which this Agreement relates (i.e., those other matters specified in Sections 2 and 8 of this Agreement), except for losses resulting from willful misfeasance, bad faith, or gross negligence in the performance of, or from disregard of, the duties of the Subadviser or any of its affiliates, partners or employees. 2 5.
