Re: SLR Investment Corp.

Registration Statement on Form N-2

Ladies and Gentlemen:

We have acted as counsel to SLR Investment Corp., a Maryland corporation (the “Company”), in connection with the preparation and filing by the Company with the Securities and Exchange Commission (the “Commission”) of an automatic shelf registration statement on Form N-2 on April 17, 2024 (the “Registration Statement”) under the Securities Act of 1933, as amended (the “Securities Act”), with respect to the offer, issuance and sale from time to time pursuant to Rule 415 under the Securities Act of up to $1,000,000,000 in aggregate offering amount of the following securities (collectively, the “Securities”):

(a) shares of the Company’s common stock, par value $0.01 per share (the “Common Stock”), including shares of Common Stock to be issued upon exercise of the Rights and/or Warrants (as such terms are defined below), or upon the conversion of any shares of Preferred Stock;

(b) shares of the Company’s preferred stock, par value $0.01 per share (the “Preferred Stock”), including shares of Preferred Stock to be issued upon exercise of the Warrants;

(c) subscription rights to purchase Common Stock (the “Rights”);

(d) debt securities of the Company, including debt securities to be issued upon exercise of the Warrants (the “Debt Securities”); and

(e) warrants representing rights to purchase Common Stock, Preferred Stock or Debt Securities (the “Warrants”).

The Registration Statement provides that the Securities may be issued from time to time, separately or together, in amounts, at prices and on terms to be set forth in one or more supplements (each, a “Prospectus Supplement”) to the final prospectus included in the Registration Statement at the time it becomes effective (the “Prospectus”).

The Debt Securities will be issued under (a) a base indenture (the “Base Indenture”), dated November 16, 2012, entered into by and between the Company and U.S. Bank National Association (the “Trustee”) and (b) one or more supplemental indentures containing the specific terms and conditions for each issuance of the Debt Securities (each a “Supplemental Indenture” and, together with the Base Indenture, the “Indenture”). The Warrants are to be issued under warrant agreements (each a “Warrant Agreement”) to be entered into by and between the Company and the purchasers thereof, or a warrant agent to be identified in the applicable warrant agreement. The Rights are to be issued under rights agreements to be entered into by and between the Company and the purchasers thereof, or a rights agent to be identified in the applicable rights agreement (the “Rights Agreement”).

This opinion is being furnished in accordance with the requirements of Item 25.2.l of Form N-2 in respect of the Rights, the Debt Securities and the Warrants.

As counsel to the Company, we have participated in the preparation of the Registration Statement and have examined the original or copy, certified or otherwise identified to our satisfaction as being a true copy of a form of Base Indenture pertaining to the Debt Securities, in the form filed as an exhibit to the Registration Statement.

With respect to such examination and our opinions expressed herein, we have assumed, without any independent investigation or verification, (i) the genuineness of all signatures on all documents submitted to us for examination, (ii) the legal capacity of all natural persons, (iii) the authenticity of all documents submitted to us as originals, (iv) the conformity to original documents of all documents submitted to us as conformed or reproduced copies and the authenticity of the originals of such copied documents, and (v) that all certificates issued by public officials have been properly issued. We also have assumed without independent investigation or verification the accuracy and completeness of all corporate records made available to us by the Company.

As to certain matters of fact relevant to the opinions in this opinion letter, we have relied upon certificates of public officials (which we have assumed remain accurate as of the date of this opinion letter) and upon certificates of officers of the Company. We have not independently established the facts, or in the case of certificates of public officials, the other statements, so relied upon. We have also relied, to the extent we have determined such reliance to be appropriate, without independent investigation and with the permission of Venable LLP, on the opinion on Venable LLP dated of even date herewith, as Maryland counsel to the Company, which is filed as Exhibit l.1 to the Registration Statement.

The opinions set forth below are limited to the effect of the laws of the State of New York as in effect on the date hereof, and we express no opinion as to the applicability or effect of the laws of any other jurisdiction.

In addition, we express no opinion herein concerning any statutes, ordinances, administrative decisions, rules or regulations of any county, town, municipality or special political subdivision (whether created or enabled through legislative action at the federal, state or regional level).

The opinions expressed below are subject to the effect of (i) applicable bankruptcy, insolvency, reorganization, receivership, moratorium, fraudulent conveyance and other similar laws affecting the rights and remedies of creditors generally, (ii) general principles of equity (including without limitation the availability of specific performance or injunctive relief and the application of concepts of materiality, reasonableness, conscionability, good faith and fair dealing), regardless of whether considered in a proceeding at law or in equity, (iii) federal and state securities laws or principles of public policy that may limit enforcement of rights to indemnity, contribution and exculpation, (iv) the effect and possible unenforceability of choice of law provisions, (v) the possible unenforceability of provisions purporting to waive rights or defenses where such waiver is against public policy, (vi) the possible unenforceability of provisions purporting to exonerate any party for negligence or malfeasance, or to negate any remedy of any party for fraud, (vii) the possible unenforceability of forum selection clauses, (viii) the possible unenforceability of provisions permitting modification of an agreement only in writing, and (ix) the possible unenforceability of provisions purporting to allow action without regard to mitigation of damages.
