Page 4 of 9

selecting a broker to effect a particular transaction to seek to obtain “best execution”, which means prompt and efficient execution of the transaction at the best obtainable price with payment of commissions which are reasonable in relation to the value of the brokerage services provided by the broker; and

Consistent with this policy, the Sub-Adviser, in selecting broker-dealers and negotiating commission rates, will take all relevant factors into consideration, including, but not limited to: the best price available; the reliability, integrity and financial condition of the broker-dealer; the size of and difficulty in executing the order; the broker’s execution capabilities and any research provided by the broker that aids the Sub-Adviser’s investment decision-making process; and the value of the expected contribution of the broker-dealer to the investment performance of the Company on a continuing basis. Subject to such policies and procedures and other written instructions as the Adviser or the Board of Directors may adopt, the Sub-Adviser shall have discretion to effect investment transactions through broker-dealers (including, to the extent permissible under applicable law, broker-dealer affiliates) who provide brokerage and/or research services, as such services are defined in section 28(e) of the 1934 Act, and to cause the Company to pay any such broker-dealers an amount of commission for effecting a portfolio investment transaction in excess of the amount of commission another broker-dealer would have charged for effecting that transaction, if the Sub-Adviser determines in good faith that such amount of commission is reasonable in relation to the value of the brokerage or research services provided by such broker-dealer, viewed in terms of either that particular investment transaction or the Sub-Adviser’s overall responsibilities with respect to the Company and other accounts to which the Sub-Adviser exercises investment discretion (as such term is defined in section 3(a)(35) of the 1934 Act. Allocation of orders placed by the Sub-Adviser on behalf of the Company to such broker-dealers shall be in such amounts and proportions as the Sub-Adviser shall determine in good faith in conformity with its responsibilities under applicable laws, rules and regulations. The Sub-Adviser will submit reports on brokerage placements to the Adviser as reasonably requested by the Adviser, in such form as may be mutually agreed to by the parties hereto, indicating the broker-dealers to whom such allocations have been made and the basis therefore.

Expenses. The Sub-Adviser shall bear all expenses incurred by it in connection with the performance of its services under this Agreement other than the cost (including brokerage commissions, transactional fees and taxes, if any) incurred in connection with purchases and sales of the Company’s portfolio securities. The Company will bear the costs or other expenses to be incurred in its operations, as agreed to by the Company, the Fund and the Adviser.

Compensation. For the services provided and the expenses assumed pursuant to this Agreement and for sub-advisory services to the Company and as sub-adviser to the Fund, the Adviser will pay and the Sub-Adviser agrees to accept as full compensation therefore, a single sub-advisory fee accrued daily and payable monthly on the average daily net assets in the Fund and the Company in accordance with Schedule B of the Fund Sub-Advisory Agreement.

8.	Services to Others. Adviser understands, and has advised the Board of Directors, that Sub-Adviser, its affiliates, principals, members, directors, officers and employees now, or

Page 5 of 9

may in the future render the same, similar or dissimilar services, including investment advisory and management services, to others, including investment companies, funds, firms, individuals, associations or accounts. Adviser has no objection to Sub-Adviser acting in such capacities and Sub-Adviser, its affiliates, principals, members, directors, officers and employees shall not be limited or restricted from providing such services, provided that whenever the Company and one or more other investment advisory clients of Sub-Adviser, its affiliates, principals, members, directors, officers and employees have available funds for investment, investments suitable and appropriate for each will be allocated in a manner believed by Sub-Adviser to be equitable to each. Sub-Adviser may group orders for the Company with orders for other funds and accounts to obtain the efficiencies that may be available on larger transactions when it determines that investment decisions are appropriate for each participating account. Sub-Adviser cannot assure that such policy will not adversely affect the price paid or received by the Company. Adviser recognizes, and has advised the Board of Directors, that in some cases this procedure may adversely affect the size and the opportunities of the position that the Company may obtain in a particular security. In addition, Adviser understands, and has advised the Board of Directors, that the persons employed by Sub-Adviser to assist in Sub-Adviser’s duties under this Agreement will not devote their full time to such service and nothing contained in this Agreement will be deemed to limit or restrict the right of Sub-Adviser or any of its affiliates to engage in and devote time and attention to other businesses or to render services of whatever kind or nature.

Limitation of Liability. Sub-Adviser, its officers, directors, employees, agents or affiliates will not be subject to any liability to the Trust, Adviser or the Company or their directors, officers, employees, agents or affiliates for any error of judgment or mistake of law or for any loss suffered by the Company, the Trust, any shareholder of the Company or the Adviser either in connection with the performance of Sub-Adviser’s duties under this Agreement or its failure to perform due to events beyond the reasonable control of the Sub-Adviser or its agents, except for a loss resulting from Sub-Adviser’s willful misfeasance, or gross negligence in the performance of its duties or by reason of its reckless disregard of its obligations and duties under this Agreement. Cayman Island, and United States’ State and Federal securities laws may impose liabilities under certain circumstances on persons who act in good faith, and therefore nothing herein shall in any way constitute a waiver or limitation of any right which Adviser may have under any applicable laws.

Under no circumstances shall any party hereto be liable to another for special, punitive or consequential damages, arising under or in connection with this Agreement, even if previously informed of the possibility of such damages.

10.

Indemnification. Adviser and the Sub-Adviser each agree to indemnify the other party (and each such party’s affiliates, employees, directors and officers) against any claim, damages, loss or liability (including reasonable attorneys’ fees) arising out of any third party claims brought against an indemnified party that are found to constitute willful misfeasance or gross negligence on the part of the indemnifying party.
