(a)will use the same skill and care in providing such services as are required to provide services to fiduciaryaccounts;

(b)will conform with all applicable provisions of the 1940 Act and rules and regulations of the Securities and Exchange Commission in all material respects and in addition will conduct its activities under this Agreement in accordance with any applicable laws and regulations of any governmental authority pertaining to its investment advisory activities, including all portfolio diversification requirements necessary for each Portfolio Segment to comply with subchapter M of the Internal Revenue Code as if it were a regulated investment companythereunder;

Segment. The Sub-Adviser agrees that it will not consult with any other sub-adviser engaged by the Adviser with respect to transactions in securities or other assets concerning a Fund Portfolio, except to the extent permitted by certain exemptive rules under the 1940 Act that permit certain transactions with a sub-adviser or its affiliates;

To assure fairtreatment of each Portfolio Segment and all other clients of Sub-Adviser in situations in which a Fund and one or more other clients’ accounts participate simultaneously in a buy or sell program involving the same security, such transactions will be allocated among each Portfolio Segment and such other clients in a manner deemed equitable by Sub-Adviser. Sub-Adviser is authorized to aggregate purchase and sale orders for securities held (or to be held) in each Portfolio Segment with similar orders being made on the same day for other eligible client accounts or portfolios managed by Sub-Adviser. When an order is so aggregated, the actual prices applicable to the aggregated transaction will be averaged and each Portfolio Segment and each other account or portfolio participating in the aggregated transaction will be treated as having purchased or sold its portion of the securities at such average price, and all transaction costs incurred in effecting the aggregated transaction will be shared on a pro-rata basis among the accounts or portfolios (including the Portfolio Segment) participating in the transaction. Adviser and the Fund understand that Sub-Adviser may not be able to aggregate transactions through brokers or dealers designated by Adviser with transactions through brokers or dealers selected by Sub-Adviser, in which event the prices paid or received by each Portfolio Segment will not be so averaged and may be higher or lower than those paid or received by other accounts or portfolios ofSub-Adviser;

(f)will report regularly to Adviser and to the Board of Directors and will make appropriate persons available for the purpose of reviewing with representatives of Adviser and the Board of Directors on a regular basis at reasonable times the management of each Portfolio Segment, including without limitation, review of the general investment strategies of each Portfolio Segment, the performance of each Portfolio Segment in relation to standard industry indices, stock market and interest rate considerations and general conditions affecting the marketplace, and will provide various other reports from time to time as reasonably requested byAdviser;

(g)will prepare such books and records with respect to each Portfolio Segment’ssecurities transactions as requested by Adviser and will furnish Adviser and the Fund’s Board of Directors such periodic and special reports as the Board or Adviser may reasonablyrequest;

(h)will vote all proxies with respect to securities in each Portfolio Segment;and

(i)will act upon reasonable instructions from Adviser which, in the reasonable determination of Sub-Adviser, are not inconsistent with Sub-Adviser’s fiduciary duties under this Agreement.
