5.Manager’s Use of the Services of Others. The Manager may (at its cost except as contemplated by Paragraph 4 of this Agreement) employ, retain or otherwise avail itself of the services or facilities of other persons or organizations for the purpose of providing the Manager or the Corporation or Fund, as appropriate, with such statistical and other factual information, such advice regarding economic factors and trends, such advice as to occasional transactions in specific securities or such other information, advice or assistance as the Manager may deem necessary, appropriate or convenient for the discharge of its obligations hereunder or otherwise helpful to the Corporation or Fund, as appropriate, or in the discharge of Manager’s overall responsibilities with respect to the other accounts which it serves as investment manager. The Manager may fully or partially delegate its duties as defined in this Agreement to a registered investment adviser (a “Subadviser”) provided the agreement between the Manager and Subadviser is approved by the Board of Directors of the Fund, and such delegation is consistent with the Act and any interpretations thereunder. The Subadviser may fully or partially delegate its duties as defined in any subadvisory agreements to another registered investment adviser (the “Delegate”), if such delegation is approved by the Board of Directors of the Fund, and such delegation is consistent with the Act and any interpretations thereunder. In connection with the delegation, the Delegate or Subadviser may be compensated from the advisory fees paid to the Manager under this Agreement. Although the fees and services under this Agreement may be transferred between the Manager, Subadviser and the Delegate, the fees and services will be limited to those specifically described in this Agreement and any investment sub-advisory agreements on behalf of the Fund.

6.Ownership of Records. All records required to be maintained and preserved by the Corporation or Fund pursuant to the provisions of rules or regulations of the Securities and Exchange Commission under Section 31(a) of the Act and maintained and preserved by the Manager on behalf of the Corporation or Fund, as appropriate, are the property of the Corporation or Fund, as appropriate, and will be surrendered by the Manager promptly on request by the Corporation or Fund, as appropriate.

7.Reports to Manager. The Corporation or Fund, as appropriate, shall furnish or otherwise make available to the Manager such prospectuses, financial statements, proxy statements, reports, and other information relating to the business and affairs of the Corporation or Fund, as appropriate, as the Manager may, at any time or from time to time, reasonably require in order to discharge its obligations under this Agreement.

8.Services to Other Clients. Nothing herein contained shall limit the freedom of the Manager or any affiliated person of the Manager to render investment supervisory and corporate administrative services to other investment companies, to act as investment manager or investment counselor to other persons, firms

or corporations, or to engage in other business activities; but so long as this Agreement or any extension, renewal or amendment hereof shall remain in effect or until the Manager shall otherwise consent, the Manager shall be the only investment manager to the Fund.

9.Limitation of Liability of Manager. Neither the Manager nor any of its officers, directors, or employees, nor any person performing executive, administrative, trading, or other functions for the Corporation or Fund (at the direction or request of the Manager) or the Manager in connection with the Manager’s discharge of its obligations undertaken or reasonably assumed with respect to this Agreement, shall be liable for any error of judgment or mistake of law or for any loss suffered by the Corporation or Fund in connection with the matters to which this Agreement relates, except for loss resulting from willful misfeasance, bad faith, or gross negligence in the performance of its or his duties on behalf of the Corporation or Fund or from reckless disregard by the Manager or any such person of the duties of the Manager under this Agreement.

10.Use of Manager’s Name. The Corporation or Fund may use the name “T. Rowe Price Institutional Income Funds, Inc.” and “T. Rowe Price Institutional Cash Reserves Fund,” or any other name derived from the name “T. Rowe Price” only for so long as this Agreement or any extension, renewal or amendment hereof remains in effect, including any similar agreement with any organization which shall have succeeded to the business of the Manager as investment manager. At such time as this Agreement or any extension, renewal or amendment hereof, or such other similar agreement shall no longer be in effect, the Corporation or Fund will (by corporate action, if necessary) cease to use any name derived from the name “T. Rowe Price,” any name similar thereto or any other name indicating that it is advised by or otherwise connected with the Manager, or with any organization which shall have succeeded to the Manager’s business as investment manager.

11.Term of Agreement.

Thereafter, this Agreement shall continue in effect from year to year, with respect to the Fund, subject to the termination provisions and all other terms and conditions hereof, so long as such continuation shall be specifically approved at least annually (a) by either the Board of Directors of the Corporation, or by vote of a majority of the outstanding voting securities of the Fund; (b) in either event by the vote, cast in person at a meeting called for the purpose of voting on such approval, of a majority of the directors of the Corporation, with respect to the Fund, who are not parties to this Agreement or interested persons of any such party; and (c) the Manager shall not have notified the Corporation, in writing, at least 60 days prior to April 30th or prior to April 30th of any year thereafter, that it does not desire such continuation. The Manager shall furnish to the Corporation, promptly upon its request, such information as may reasonably be necessary to evaluate the terms of this Agreement or any extension, renewal or amendment hereof.

12.Assignment and Amendment of Agreement. This Agreement shall automatically and immediately terminate in the event of its assignment. This Agreement may not be amended except pursuant to a written instrument executed on behalf of both parties. In the case of the Fund, approval of any such amendment shall be by resolution of a majority of the directors who are not parties to this Agreement or interested persons of any such party, and, if required by the 1940 Act, by the affirmative vote of a majority of the outstanding voting securities of the Fund.

13.Termination of Agreement. This Agreement may be terminated by either party hereto, without the payment of any penalty, upon 60 days’ prior notice in writing to the other party; provided, that in the case of termination by the Corporation, with respect to the Fund, such action shall have been authorized by resolution of a majority of the directors of the Corporation who are not parties to this Agreement or interested persons of any such party, or by vote of a majority of the outstanding voting securities of the Fund.

14.Miscellaneous.

A.Captions. The captions in this Agreement are included for convenience of reference only and in no way define or delineate any of the provisions hereof or otherwise affect their construction or effect.

B.Interpretation. Nothing herein contained shall be deemed to require the Corporation to take any action contrary to its Articles of Incorporation or By-Laws, or any applicable statutory or regulatory requirement to which it is subject or by which it is bound, or to relieve or deprive the Board of Directors of the Corporation of its responsibility for and control of the conduct of the affairs of the Fund.

C.Definitions. Any question of interpretation of any term or provision of this Agreement having a counterpart in or otherwise derived from a term or provision of the 1940 Act shall be resolved by reference to such term or provision of the 1940 Act and to interpretations thereof, if any, by the United States courts or, in the absence of any controlling decision of any such court, by rules, regulations or orders of the SEC validly issued pursuant to the 1940 Act. As used in this agreement, the terms “majority of the outstanding voting securities,” “affiliated person,” “interested person,” “assignment,” “broker,” “investment adviser,” “net assets,” “sale,” “sell,” and “security” shall have the meaning as such terms have in the 1940 Act, subject to such exemption as may be granted by the SEC by any rule, regulation, or order. Where the effect of a requirement of the federal securities laws reflected in any provision of this Agreement is made less restrictive by a rule, regulation, or order of the SEC, whether of special or of general application, such provision shall be deemed to incorporate the effect of such rule, regulation or order.
