Ladies and Gentlemen:

We have acted as counsel to CĪON Investment Corporation, a Maryland corporation (the "Company"), in connection with the preparation and filing by the Company with the Securities and Exchange Commission (the "Commission") of a registration statement on Form N-2, filed with the Commission on April 12, 2024 (as amended from time to time, the "Registration Statement"), under the Securities Act of 1933, as amended (the "Securities Act"), relating to possible offerings from time to time of up to an aggregate of $350,000,000 of the following securities of the Company: (1) shares of common stock, $0.001 par value per share, of the Company (“Common Stock”), (2) shares of preferred stock of the Company (“Preferred Stock”), (3) subscription rights to purchase Common Stock (“Subscription Rights”), (4) debt securities (“Debt Securities”) to be issued pursuant to a base indenture (“Indenture”) between the Company and U.S. Bank Trust Company, National Association, as trustee (the “Trustee”) and (5) warrants to purchase Common Stock, Preferred Stock or Debt Securities (“Warrants”). The Common Stock, Preferred Stock, Subscription Rights, Debt Securities and Warrants are collectively referred to herein as the “Securities.”

The Registration Statement provides that the Securities may be issued from time to time in amounts, at prices, and on terms to be set forth in one or more supplements to the final prospectus included in the Registration Statement at the time it becomes effective or in one or more free writing prospectuses.

As counsel to the Company, we have participated in the preparation of the Registration Statement and have examined and relied on originals or copies, certified or otherwise identified to our satisfaction, of such documents, corporate records and other instruments 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 opinions set forth below, including the following documents:

2. the Third Articles of Amendment and Restatement of the Articles of Incorporation of the Company, as amended (the "Charter");

3. the Bylaws of the Company (the "Bylaws");

4. a form of the Indenture;

5. forms of certificates evidencing the Common Stock and the Subscription Rights;

6. the form of warrant agreement;

10. the resolutions of the board of directors (the "Board") of the Company relating to, among other things, the authorization and approval of the preparation and filing of the Registration Statement (the "Resolutions").

We have not independently established the facts, or in the case of certificates of public officials, the other statements, so relied upon.

This opinion letter is limited to the effect of the Maryland General Corporation Law (the "MGCL") and as to the Debt Securities, the Rights and the Warrants constituting valid and legally binding obligations of the Company, the laws of the State of New York, in each case, as in effect on the date hereof, and we express no opinion as to the applicability or effect of any other laws of the State of Maryland or the laws of any other jurisdictions. Without limiting the preceding sentence, we express no opinion as to any federal or state securities or broker-dealer laws or regulations thereunder relating to the offer, issuance and sale of the Securities pursuant to the Registration Statement. This opinion letter has been prepared, and should be interpreted, in accordance with customary practice followed in the preparation of opinion letters by lawyers who regularly give, and such customary practice followed by lawyers who on behalf of their clients regularly advise opinion recipients regarding, opinion letters of this kind.
