C. IICO or an affiliate of IICO, may also act as (i) transfer agent or shareholder servicing agent of the Corporation and/or as (ii) accounting services agent of the Corporation if at the time in question there is a separate agreement, “Shareholder Servicing Agreement” and/or “Accounting Services Agreement,” covering such functions between the Corporation and IICO, or such affiliate. The corporation, whether IICO, or its affiliate, which is the party to either such Agreement with the Corporation is referred to as the “Agent.” Each such Agreement shall provide in substance that it shall go into effect, or be amended, or a new agreement covering the same topics between the Corporation and the Agent may be entered into, only if the terms of such Agreement, such amendment or such new agreement have been approved by the Board of Directors of the Corporation, including the vote of a majority of the directors who are not “interested persons” as defined in the Investment Company Act of 1940, of either party to the Agreement, such amendment or such new agreement (considering IICO to be such a party even if at the time in question the Agent is an affiliate of IICO), cast in person at a meeting called for the purpose of voting on such approval. Such a vote is referred to as a “disinterested director” vote. Each such Agreement shall also provide in substance for its continuance, unless terminated, for a specified period which shall not exceed two years from the date of its execution and from year to year thereafter only if such continuance is specifically approved at least annually by a disinterested director vote, and that any disinterested director vote shall include a determination that (i) the Agreement, amendment, new agreement or continuance in question is in the best interests of the Corporation and its shareholders; (ii) the services to be performed under the Agreement, the Agreement as amended, new agreement or agreement to be continued are services required for the operation of the Corporation; (iii) the Agent can provide services the nature and quality of which are at least equal to those provided by others offering the same or similar services; and (iv) the fees for such services are fair and reasonable in light of the usual and customary charges made by others for services of the same nature and quality. Any such Agreement may also provide in substance that any disinterested director vote may be conditioned on the favorable vote of the holders of a majority (as defined in or under the Investment Company Act of 1940) of the outstanding shares of each class or series of the Corporation. Any such Agreement shall also provide in substance that it may be terminated by the Agent at any time without penalty upon giving the Corporation one hundred twenty (120)

3

days’ written notice (which notice may be waived by the Corporation) and may be terminated by the Corporation at any time without penalty upon giving the Agent sixty (60) days’ written notice (which notice may be waived by the Agent), provided that such termination by the Corporation shall be directed or approved by the vote of a majority of the Board of Directors of the Corporation in office at the time or by the vote of the holders of a majority (as defined in or under the Investment Company Act of 1940) of the outstanding shares of each class or series of the Corporation.

IV.        Brokerage

(a)    IICO may select brokers to effect the portfolio transactions of the Corporation on the basis of its estimate of their ability to obtain, for reasonable and competitive commissions, the best execution of particular and related portfolio transactions. For this purpose, “best execution” means prompt and reliable execution at the most favorable price obtainable. Such brokers may be selected on the basis of all relevant factors including the execution capabilities required by the transaction or transactions, the importance of speed, efficiency, or confidentiality, and the willingness of the broker to provide useful or desirable investment research and/or special execution services. IICO shall have no duty to seek advance competitive commission bids and may select brokers based solely on its current knowledge of prevailing commission rates.

(b)    Subject to the foregoing, IICO shall have discretion, in the interest of the Corporation, to direct the execution of its portfolio transactions to brokers who provide brokerage and/or research services (as such services are defined in Section 28(e) of the Securities Exchange Act of 1934) for the Corporation and/or other accounts for which IICO or one or more of its affiliates exercise “investment discretion” (as that term is defined in Section 3(x)(35) of the Securities Exchange Act of 1934); and in connection with such transactions, to pay commission in excess of the amount another adequately qualified broker would have charged if IICO determines, in good faith, that such commission is reasonable in relation to the value of the brokerage and/or research services provided by such broker, viewed in terns of either that particular transaction or the overall responsibilities of IICO and its investment advisory affiliates with respect to the accounts for which they exercise investment discretion. In reaching such determination, IICO will not be required to attempt to place a specified dollar amount on the brokerage and/or research services provided by such broker; provided that IICO shall be prepared to demonstrate that such determinations were made in good faith, and that all commissions paid by the Corporation over a representative period selected by its Board of Directors were reasonable in relation to the benefits to the Corporation.

V.        Compensation of IICO

As compensation in full for services rendered and for the facilities and personnel furnished under sections 1, II, and IV of this Agreement, the Corporation will pay to IICO for each day the fees specified in Exhibit A hereto.

The amounts payable to IICO shall be determined as of the close of business each day; shall, except as set forth below, be based upon the value of net assets computed in accordance with the Articles of Incorporation of the Corporation; and shall be paid in arrears whenever requested by 11CO.

4

shall be excluded the amount owed to the Corporation with respect to shares which have been sold but not yet paid to the Corporation by Waddell & Reed, Inc.

Notwithstanding the foregoing, if the laws, regulations or policies of any state in which shares of the Corporation are qualified for sale limit the operation and management expenses of the Corporation, IICO will refund to the Corporation the amount by which such expenses exceed the lowest of such state limitations.

VI.        Undertakings of IICO Liabilities
