On its own initiative, JH Advisers will apprise JHLICO and the Trust of important political and economic developments materially affecting the marketplace or the Subject Fund, and will furnish JHLICO and the Trust's Board of Trustees from time to time such information as is appropriate for this purpose. JH Advisers will also make its personnel available in Boston or other reasonable locations as often as quarterly to discuss the Subject Fund and JH Advisers' management thereof, to educate JHLICO sales personnel with respect thereto, and for such other purposes as the Trust or JHLICO may reasonably request. The Trust and JHLICO will provide timely information to JH Advisers regarding such matters as purchases and redemptions of shares in the Subject Fund and the cash requirements of, and cash available for investment in, the Fund. JHLICO will timely provide JH Advisers with copies of monthly accounting statements for the Subject Fund, and such other information (including, without limitation, reports concerning the classification of portfolio securities of the Subject Fund for purposes of Subchapter M of the Internal Revenue Code and Treasury Regulations Section 1.817) as may be reasonably necessary or appropriate in order for JH Advisers to perform its responsibilities hereunder. 3. ALLOCATION OF EXPENSES. Each party to this Agreement shall bear the costs and expenses of performing its obligations hereunder. In this regard, the Trust specifically agrees to assume the expense of: (a) brokerage commissions for transactions in the portfolio investments of the Trust and similar fees and charges for the acquisition, disposition, lending or borrowing of such portfolio investments; (b) custodian fees and expenses; (c) all taxes, including issuance and transfer taxes, and reserves for taxes payable by the Trust to federal, state or other governmental agencies; and (d) interest payable on the Trust's borrowings. Nothing in this Agreement shall alter the allocation of expenses and costs agreed upon between the Trust and JHLICO in the Investment Management Agreement or any other agreement to which they are parties. 3 4. SUB-ADVISORY FEES. For all of the services rendered with respect to the Subject Fund as herein provided, JHLICO shall pay to JH Advisers a fee (for the payment of which the Trust shall have no obligation or liability), based on the Current Net Assets of the Subject Fund, as set forth in Schedule I attached hereto and made a part hereof. Such fee shall be accrued daily and payable monthly, as soon as practicable after the last day of each calendar month. In the case of termination of this Agreement with respect to the Subject Fund during any calendar month, the fee with respect to such Fund accrued to but excluding the date of termination shall be paid promptly following such termination. For purposes of computing the amount of advisory fee accrued for any day, "Current Net Assets" shall mean the Subject Fund's net assets as of the most recent preceding day for which that Subject Fund's net assets were computed. 5. FUND TRANSACTIONS. In connection with the investment and reinvestment of the assets of the Subject Fund, JH Advisers is authorized to select the brokers or dealers that will execute purchase and sale transactions for the Fund and to use its best efforts to obtain the best available price and most favorable execution with respect to all such purchases and sales of portfolio securities for said Fund. JH Advisers shall maintain records adequate to demonstrate compliance with this requirement. Subject to this primary requirement, and maintaining as its first consideration the benefits to the Subject Fund and its shareholders, JH Advisers shall have the right subject to the control of the Board of Trustees, and to the extent authorized by the Securities Exchange Act of 1934, to follow a policy of selecting brokers who furnish brokerage and research services to the Subject Fund or to JH Advisers, and who charge a higher commission rate to the Subject Fund than may result when allocating brokerage solely on the basis of seeking the most favorable price and execution. JH Advisers shall determine in good faith that such higher cost was reasonable in relation to the value of the brokerage and research services provided. JH Advisers will not receive any tender offer solicitation fees or similar payments in connection with the tender of investments of any Fund. 6. OWNERSHIP OF INFORMATION, RECORDS, AND CONFIDENTIALITY. The Trust shall own and control all records maintained hereunder by JH Advisers on the Trust's behalf and, in the event of termination of this Agreement with respect to any Subject Fund for any reason, all records relating to that Fund shall be promptly returned to the Trust, free from any claim or retention of rights by JH Advisers, provided that (subject to the last paragraph of this Section 6) JH Advisers may retain copies of such records. JH Advisers also agrees, upon request of the Trust, promptly to surrender such books and records or, at its expense, copies thereof, to the Trust or make such books and records available for audit or inspection by representatives of regulatory authorities or other persons reasonably designated by the Trust. JH Advisers further agrees to maintain, prepare and preserve such books and records in accordance with the 1940 Act and rules thereunder, including but not limited to Rules 31a-1 and 31a-2, and to supply all information requested by any insurance regulatory authorities to determine whether all insurance laws and regulations are being complied with. JH Advisers shall supply the Board of Trustees and officers of the Trust and JHLICO with all statistical information regarding investments which is reasonably required by them and reasonably available to JH Advisers. JH Advisers shall not disclose or use any records or information obtained pursuant hereto in any manner whatsoever except as expressly authorized herein, and will keep confidential any information obtained pursuant hereto, and disclose such information only if the Trust has authorized such disclosure, or (after reasonable notice to the Trust) if such disclosure is expressly requested by applicable federal or state regulatory authorities. 4 7. LIABILITY; STANDARD OF CARE. No provision of this Agreement shall be deemed to protect JH Advisers or JHLICO against any liability to the Trust or its shareholders to which it might otherwise be subject by reason of any willful misfeasance, bad faith or negligence in the performance of its duties or the reckless disregard of its obligations and duties under this Agreement or the Investment Management Agreement. Nor shall any provision hereof be deemed to protect any trustee or officer of the Trust against any such liability to which he might otherwise be subject by reason of any willful misfeasance, bad faith or negligence in the performance his duties or the reckless disregard of his obligations and duties. Adviser shall employ only qualified personnel to manage the Subject Fund; shall comply with all applicable laws and regulations in the discharge of its duties under this Agreement; shall (as provided in Section 2 above) comply with the investment policies, guidelines and restrictions of the Subject Fund and with the provisions of the Trust's Declaration of Trust, Bylaws, prospectus and statement of additional information; shall manage the Subject Fund (subject to the receipt of, and based upon the information contained in, periodic reports from JHLICO or the custodian concerning the classification of Fund securities for such purposes) as a regulated investment company in accordance with subchapter M of the Internal Revenue Code of 1986, as amended (the "Code"), and Treasury Regulations Section 1.817-5(b); shall act at all times in the best interests of the Trust; and shall discharge its duties with the care, skill, prudence and diligence under the circumstances then prevailing that a prudent person acting in a like capacity and familiar with such matters would use in the conduct of a similar enterprise. However, JH Advisers shall not be obligated to perform any service not described in this Agreement, and shall not be deemed by virtue of this Agreement to have made any representation or warranty that any level of investment performance or level of investment results will be achieved. 8. DURATION AND TERMINATION OF THIS AGREEMENT. (a) Duration. This Agreement shall become effective with respect to the Subject Fund on the date hereof and, with respect to any additional Subject Fund, on the date of receipt by the Trust of notice from JH Advisers in accordance with Paragraph 1(b) hereof that it is willing to serve with respect to such Fund.
