    Re:    Prospect Capital Corporation Shelf Registration Statement on Form N-2

Ladies and Gentlemen:

We have acted as special New York counsel to Prospect Capital Corporation, a Maryland corporation (the “Company”), in connection with the registration statement on Form N-2 (the “Registration Statement”) to be filed on the date hereof by the Company with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Securities Act”). The Registration Statement relates to the issuance and sale by the Company from time to time, pursuant to Rule 415 of the General Rules and Regulations of the Commission promulgated under the Securities Act (the “Rules and Regulations”), of an unspecified amount of securities of the Company, consisting of, among other things, (i) debt securities of the Company (the “Debt Securities”), which may be issued in one or more series under an indenture, dated as of February 16, 2012 (the “Indenture”), between the Company and American Stock Transfer & Trust Company, LLC, as trustee (the “Original Trustee”), as amended by the Agreement of Resignation, Appointment and Acceptance, dated as of March 12, 2012, by and among the Company, the Original Trustee and U.S. Bank National Association, as trustee (the “Agreement of Resignation, Appointment and Acceptance”), each as incorporated by reference as an exhibit to the Registration Statement, and (ii) such indeterminate amount of Debt Securities as may be issued upon conversion, exchange or exercise, as applicable, of any Debt Securities or other securities of the Company.

.

This opinion is being furnished in accordance with the requirements of sub paragraph (l) of item 25.2 of part C of Form N-2.

In rendering the opinion stated herein, we have examined and relied upon the following:

(a)the Registration Statement; and

(b)an executed copy of the Indenture.

We have also examined originals or copies, certified or otherwise identified to our satisfaction, of such records of the Company and such agreements, certificates and receipts of public officials, certificates of officers or other representatives of the Company and others, and such other documents as we have deemed necessary or appropriate as a basis for the opinion stated below.

In our examination, we have assumed the genuineness of all signatures, the legal capacity and competency of all natural persons, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as facsimile,

electronic, certified or photocopied copies, and the authenticity of the originals of such copies. As to any facts relevant to the opinion stated herein that we did not independently establish or verify, we have relied upon statements and representations of officers and other representatives of the Company and others and of public officials, including the factual representations and warrants contained in the Transaction Documents.

We do not express any opinion with respect to the laws of any jurisdiction other than the laws of the State of New York (“Opined-on Law”).

As used herein, “Transaction Documents” means the Indenture, the Agreement of Resignation, Appointment and Acceptance and the supplemental indentures thereto and any applicable underwriting or purchase agreement.

The opinion stated below presumes that all of the following (collectively, the “general conditions”) shall have occurred prior to the issuance of the Debt Securities:

(i) the Registration Statement, as finally amended (including all necessary post-effective amendments), has become effective under the Securities Act;

(ii) an appropriate prospectus supplement or term sheet with respect to such Debt Securities has been prepared, delivered and filed in compliance with the Securities Act and the applicable Rules and Regulations;

(iii) the applicable Transaction Documents shall have been duly authorized, executed and delivered by the Company and the other parties thereto, including, if such Debt Securities are to be sold or otherwise distributed pursuant to a firm commitment underwritten offering or other offering with underwriters or agents, the underwriting, sales agent or other agreement or purchase agreement with respect thereto;

(iv) the board of directors of the Company, including any duly authorized committee thereof, shall have taken all necessary corporate action to approve the issuance and sale of such Debt Securities and related matters and appropriate officers of the Company have taken all related action as directed by or under the direction of the board of directors of the Company; and

(v) the terms of the applicable Transaction Documents and the issuance and sale of such Debt Securities have been duly established in conformity with the articles of amendment and restatement of the Company so as not to violate any applicable law, the articles of amendment and restatement of the Company or the by-laws of the Company, or result in a default under or breach of any agreement or instrument binding upon the Company, and so as to comply with any requirement or restriction imposed by any court or governmental body having jurisdiction over the Company.

Based upon the foregoing and subject to the qualifications and assumptions stated herein, we are of the opinion that, with respect to any series of Debt Securities offered by the Company (the “Offered Debt Securities”), when (a) the general conditions shall have been satisfied, (b) the issuance, sale and terms of the Offered Debt Securities and related matters have been approved and established in conformity with the applicable Transaction Documents and (c) the certificates evidencing the Offered Debt Securities have been issued in a form that complies with the provisions of the applicable Transaction Documents and have been duly executed and authenticated in accordance with the provisions of the Indenture and any other
