PROXY STATEMENT

2018 Annual Meeting of Stockholders

This Proxy Statement is furnished in connection with the solicitation of proxies by the board of directors of Solar Senior Capital Ltd. (“Solar Senior Capital,” the “Company,” “we,” “us” or “our”) for use at the Company’s 2018 Annual Meeting of Stockholders (the “Meeting”) to be held on May 22, 2018 at 10:15 a.m., Eastern Time, at the offices of Eversheds Sutherland (US) LLP located at 1114 Avenue of the Americas, 40th Floor, New York, New York 10036 and at any postponements or adjournments thereof. This Proxy Statement, the accompanying proxy card and the Company’s Annual Report for the fiscal year ended December 31, 2017, are first being sent to stockholders on or about [            ], 2018.

We encourage you to vote your shares, either by voting in person at the Meeting or by granting a proxy (i.e., authorizing someone to vote your shares). If you properly sign and date the accompanying proxy card or vote by telephone or through the Internet, and the Company receives it in time for voting at the Meeting, the persons named as proxies will vote your shares in the manner that you specify. If you give no instructions on the proxy card, the shares covered by the proxy card will be voted FOR the election of the nominee as a director and FOR the other matters listed in the accompanying Notice of Annual Meeting of Stockholders.

If you are a “stockholder of record” (i.e., you hold shares directly in your name), you may revoke a proxy at any time before it is exercised by notifying the proxy tabulator, Broadridge Financial Solutions, Inc. (“Broadridge”), in writing, by submitting a properly executed, later-dated proxy, or by voting in person at the Meeting. Please send your notification to Solar Senior Capital Ltd., c/o Broadridge Financial Solutions, Inc., 51 Mercedes Way, Edgewood, NY 11717. Any stockholder of record attending the Meeting may vote in person whether or not he or she has previously voted his or her shares. If your shares are held for your account by a broker, bank or other institution or nominee (“Broker Shares”), you may vote such shares at the Meeting only if you obtain proper written authority from your institution or nominee and present it at the Meeting. All of our directors are encouraged to attend the Meeting. Stockholders have no dissenters’ or appraisal rights in connection with any of the proposals described herein.

Stockholders of record may also vote either via the Internet or by telephone. Specific instructions to be followed by stockholders of record interested in voting via the Internet or the telephone are shown on the enclosed proxy card. The Internet and telephone voting procedures are designed to authenticate the stockholder’s identity and to allow stockholders to vote their shares and confirm that their instructions have been properly recorded.

Purpose of Meeting

At the Meeting, you will be asked to vote on the following proposals:

1. To elect one director of the Company, who will serve for a term of three years, or until his successor is duly elected and qualified;

2. To approve a proposal to authorize the Company to sell shares of its common stock at a price or prices below the Company’s then current net asset value per share in one or more offerings, in each case subject to the approval of its board of directors and compliance with the conditions set forth in the proxy statement (including, without limitation, that the number of shares issued does not exceed 25% of the Company’s then outstanding common stock immediately prior to each such offering); and

3. To transact such other business as may properly come before the meeting.

Voting Securities

You may vote your shares, in person or by proxy, at the Meeting only if you were a stockholder of record at the close of business on March 27, 2018 (the “Record Date”). There were [            ] shares of the Company’s common stock outstanding on the Record Date. Each share of the common stock is entitled to one vote.

Quorum Required

A quorum must be present at the Meeting for any business to be conducted. The presence at the Meeting, in person or by proxy, of the holders entitled to cast a majority of the shares of common stock of the Company entitled to be cast on the record date will constitute a quorum. Abstentions will be treated as shares present for quorum purposes. Broker shares for which the nominee has not received voting instructions from the record holder and does not have discretionary authority to vote the shares on certain proposals (which are considered “Broker Non-Votes” with respect to such proposals) will be treated as shares present for quorum purposes. If a quorum is not present at the Meeting, the Chairman of the board of directors may adjourn the Meeting to permit further solicitation of proxies

Vote Required

Election of Director. The election of a director requires the affirmative vote of a plurality of the votes cast at the Meeting in person or by proxy. Stockholders may not cumulate their votes. If you vote “Withhold Authority” with respect to a nominee, your shares will not be voted with respect to the person indicated. Because directors are elected by plurality of the votes, and there are not more candidates seeking election than there are seats on the board of directors up for election at the Meeting, if the nominee receives at least one “FOR” vote, then it is expected that the nominee will be elected to the board of directors. Abstentions and Broker Non-Votes will not be included in determining the number of votes cast and, as a result, will have no effect on this proposal.

Approval of a Proposal to Authorize the Company to Sell Shares of its Common Stock at a Price or Prices Below the Company’s then Current Net Asset Value Per Share in One or More Offerings, in Each Case Subject to the Approval of its Board of Directors and Compliance with the Conditions Set Forth in the Proxy Statement (Including, Without Limitation, that the Number of Shares Issued Does Not Exceed 25% of the Company’s then Outstanding Common Stock Immediately Prior to Each Such Offering). The affirmative vote of (1) a majority of the outstanding shares of common stock entitled to vote at the Meeting; and (2) a majority of the outstanding shares of common stock entitled to vote at the Meeting that are not held by affiliated persons of the Company is required to approve this proposal. For purposes of this proposal, the Investment Company Act of 1940, as amended (the “1940 Act”), defines “a majority of the outstanding shares” as: (1) 67% or more of the voting securities present at the Meeting if the holders of more than 50% of the outstanding voting securities of such company are present or represented by proxy; or (2) 50% of the outstanding voting securities of the Company, whichever is the less. Abstentions and Broker Non-Votes will have the effect of a vote against this proposal.

Additional Solicitation. If there are not enough votes to approve any proposals at the Meeting, the stockholders who are represented may adjourn the Meeting to permit the further solicitation of proxies. The persons named as proxies will vote for such adjournment, unless such proxies are marked to be voted against any proposal for which an adjournment is sought, in order to permit the further solicitation of proxies.

Also, a stockholder vote may be taken on one or more of the proposals in this Proxy Statement prior to any such adjournment if there are sufficient votes for approval of such proposal(s).

Information Regarding This Solicitation

Our board of directors is making this proxy solicitation and the Company will bear the expense of the solicitation of proxies for the Meeting, including the cost of preparing, printing and mailing this Proxy Statement,

2

the accompanying Notice of Annual Meeting of Stockholders, and proxy card. If brokers, trustees, or fiduciaries and other institutions or the nominee holding shares in his name, or in the name of the nominee, which are beneficially owned by others, forward the proxy materials to, and obtain proxies from, such beneficial owners, we will reimburse such persons for their reasonable expenses in so doing. In addition, we will indemnify them against any losses arising out of that firm’s proxy soliciting services on our behalf.

In addition to the solicitation of proxies by the use of the mail, proxies may be solicited in person and/or by telephone or facsimile transmission by directors, officers or employees of the Company and/or officers or employees of Solar Capital Partners, LLC (“Solar Capital Partners”), the Company’s investment adviser. Solar Capital Partners and Solar Capital Management, LLC (“Solar Capital Management”), the Company’s administrator, are both located at 500 Park Avenue, New York, New York 10022. No additional compensation will be paid to directors, officers or regular employees of the Company or Solar Capital Partners for such services. The Company has also retained Morrow Sodali, LLC, 470 West Ave, Stamford, CT 06902, to assist in the solicitation of proxies for the Meeting for a fee of approximately $10,000, plus reimbursement of certain out of pocket expenses.

Stockholders may also provide their voting instructions by telephone or through the Internet. These options require stockholders to input the Control Number, which is located on each proxy card. After inputting this number, stockholders will be prompted to provide their voting instructions. Stockholders will have an opportunity to review their voting instructions and make any necessary changes before submitting their voting instructions and terminating their telephone call or Internet link. Stockholders who vote via the Internet, in addition to confirming their voting instructions prior to submission, will also receive an e-mail confirming their instructions upon request.

If a stockholder wishes to participate in the Meeting, but does not wish to give a proxy by telephone or electronically, the stockholder may still submit the proxy card originally sent with this Proxy Statement or attend the Meeting in person.

Any proxy given pursuant to this solicitation may be revoked by notice from the person giving the proxy at any time before it is exercised. Any such notice of revocation should be provided in writing and signed by the stockholder in the same manner as the proxy being revoked and delivered to the Company’s proxy tabulator.

Security Ownership of Certain Beneficial Owners and Management

The following table sets forth, as of the Record Date, the beneficial ownership of each current director, the nominee for director, the Company’s executive officers, each person known to us to beneficially own 5% or more of the outstanding shares of our common stock, and the executive officers and directors as a group.

Beneficial ownership is determined in accordance with the rules of the Securities and Exchange Commission (“SEC”) and includes voting or investment power with respect to the securities. Ownership information for those persons who beneficially own 5% or more of our shares of common stock is based upon reports filed by such persons with the SEC and other information obtained from such persons, if available.

3

Unless otherwise indicated, the Company believes that each beneficial owner set forth in the table has sole voting and investment power and has the same address as the Company. Our address is 500 Park Avenue, New York, New York 10022.

4

Set forth below is the dollar range of equity securities beneficially owned by each of our directors as of the Record Date. We are not part of a “family of investment companies,” as that term is defined in the 1940 Act.

PROPOSAL I: ELECTION OF DIRECTOR

Pursuant to the Company’s charter and bylaws, the board of directors is divided into three classes. Directors are elected for a staggered term of three years each, with a term of office of one of the three classes of directors expiring each year. Each director will hold office for the term to which he is elected or until his successor is duly elected and qualified.

Mr. David S. Wachter has been nominated for election for a three-year-term expiring in 2021. If elected, Mr. Wachter will continue to serve on the Company’s Audit Committee, Nominating and Corporate Governance Committee and Compensation Committee. Mr. Wachter is not being proposed for election pursuant to any agreement or understanding between Mr. Wachter and the Company or any other person or entity.

A stockholder can vote for or withhold his or her vote from the nominee. In the absence of instructions to the contrary, it is the intention of the persons named as proxies to vote such proxy “FOR” the election of the nominee named below. If the nominee should decline or be unable to serve as a director, it is intended that the proxy will vote for the election of such person as is nominated by the board of directors as a replacement. The board of directors has no reason to believe that the person named below will be unable or unwilling to serve.

THE BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE “FOR” THE ELECTION OF THE NOMINEE NAMED IN THIS PROXY STATEMENT.

Information about the Nominee and Directors

As described below under “Committees of the Board of Directors—Nominating and Corporate Governance Committee,” the board of directors has identified certain desired attributes for director nominees. Each of our directors and the director nominee has demonstrated high character and integrity, superior credentials and recognition in his respective field and the relevant expertise and experience upon which to be able to offer advice and guidance to our management. Each of our directors and the director nominee also has sufficient time available to devote to the affairs of the Company, is able to work with the other members of the board of directors and contribute to the success of the Company and can represent the long-term interests of the Company’s stockholders as a whole. Our directors and the director nominee have been selected such that the board of directors represents a range of backgrounds and experiences.

Certain information, as of the Record Date, with respect to the director nominee for election at the Meeting, as well as each of the current directors, is set forth below, including their names, ages, a brief description of their recent business experience, including present occupations and employment, certain directorships that each person holds, the year in which each person became a director of the Company, and a discussion of their particular experience, qualifications, attributes or skills that lead us to conclude, as of the Record Date, that such individual should serve as a director of the Company, in light of the Company’s business and structure. There were no legal proceedings of the type described in Item 401(f)(7) and (8) of Regulation S-K in the past 10 years against any of the directors, director nominee, or officers of the Company and none are currently pending.

Nominee for Director

Mr. Wachter is not an “interested person” of the Company as defined in the 1940 Act.

6

Nominee for Class I Director—Term Expiring 2021

Mr. Wachter’s extensive knowledge of private equity and investment banking provides the board of directors with the valuable insight of an experienced financial manager.

Current Directors

Mr. Gross is an “interested person” of the Company as defined in the 1940 Act due to his position as the Chief Executive Officer and President of the Company and a managing member of Solar Capital Partners, the Company’s investment adviser. Mr. Spohler is an “interested person” of the Company as defined in the 1940 Act due to his position as the Chief Operating Officer of the Company and a managing member of Solar Capital Partners, the Company’s investment adviser. Each of Mr. Hochberg and Mr. Potter is not an “interested person” of the Company as defined in the 1940 Act.

Class II Directors—Term Expiring 2019

Mr. Spohler’s depth of experience in managerial positions in investment management, leveraged finance and financial services, as well as his intimate knowledge of the Company’s business and operations, gives the board of directors valuable industry-specific knowledge and expertise on these and other matters.

7

Mr. Hochberg’s varied experience in investing in medical technology companies provides the board of directors with particular knowledge of this field, and his role as chairman of other companies’ board of directors brings the perspective of a knowledgeable corporate leader.

8

Class III Directors—Term Expiring 2020

Mr. Gross’ intimate knowledge of the business and operations of Solar Capital Partners, extensive familiarity with the financial industry and the investment management process in particular, and experience as a director of other public and private companies gives the board of directors valuable insight and positions him well to continue to serve as the Chairman of our board of directors.

9

Mr. Potter’s experience practicing as a corporate lawyer provides valuable insight to the board of directors on regulatory and risk management issues. In addition, his tenure in private equity and other investments and service as a director of both public and private companies provide industry-specific knowledge and expertise to the board of directors.

10

Information about Executive Officers Who Are Not Directors

The following information, as of the Record Date, pertains to our executive officers who are not directors of the Company.

Director Independence

In accordance with rules of the NASDAQ Stock Market, our board of directors annually determines each director’s independence. We do not consider a director independent unless the board of directors has determined that he has no material relationship with us. We monitor the relationships of our directors and officers through a questionnaire each director completes no less frequently than annually and updates periodically as information provided in the most recent questionnaire changes.

Our governance guidelines require any director who has previously been determined to be independent to inform the Chairman of the board of directors, the Chairman of the Nominating and Corporate Governance Committee and our Corporate Secretary of any change in circumstance that may cause his status as an independent director to change. The board of directors limits membership on the Audit Committee, the Nominating and Corporate Governance Committee and the Compensation Committee to independent directors.

In order to evaluate the materiality of any such relationship, the board of directors uses the definition of director independence set forth in the rules promulgated by the NASDAQ Stock Market. Rule 5605(a)(2) provides that a director of a BDC, shall be considered to be independent if he or she is not an “interested person” of the Company, as defined in Section 2(a)(19) of the 1940 Act.

The board of directors has determined that each of the directors is independent and has no relationship with us, except as a director and stockholder, with the exception of Michael S. Gross, as a result of his positions as the Chief Executive Officer and President of the Company and a managing member of Solar Capital Partners, and Bruce Spohler, as a result of his position as Chief Operating Officer of the Company and a managing member of Solar Capital Partners.

11

Board Leadership Structure

Our board of directors monitors and performs an oversight role with respect to the business and affairs of Solar Senior Capital, including with respect to investment practices and performance, compliance with regulatory requirements and the services, expenses and performance of service providers to Solar Senior Capital. Among other things, our board of directors approves the appointment of Solar Capital Partners, our investment adviser, and officers, reviews and monitors the services and activities performed by Solar Capital Partners and executive officers and approves the engagement, and reviews the performance of, our independent public accounting firm.

Under Solar Senior Capital’s bylaws, our board of directors may designate a chairman to preside over the meetings of the board of directors and meetings of the stockholders and to perform such other duties as may be assigned to him by the board of directors. We do not have a fixed policy as to whether the chairman of the board of directors should be an independent director and believe that we should maintain the flexibility to select the chairman and reorganize the leadership structure, from time to time, based on the criteria that is in the best interests of Solar Senior Capital and its stockholders at such times.

Presently, Mr. Gross serves as the Chairman of our board of directors. Mr. Gross is an “interested person” of Solar Senior Capital as defined in Section 2(a)(19) of the 1940 Act because he is the President and Chief Executive Officer of Solar Senior Capital, serves on the investment committee of Solar Capital Partners and is a managing member of Solar Capital Partners. We believe that Mr. Gross’ history with Solar Senior Capital, familiarity with its investment platform, and extensive knowledge of the financial services industry and the investment valuation process in particular qualify him to serve as the Chairman of our board of directors. We believe that Solar Senior Capital is best served through this existing leadership structure, as Mr. Gross’ relationship with Solar Senior Capital Partners provides an effective bridge and encourages an open dialogue between management and the board of directors, ensuring that both groups act with a common purpose.

Our board of directors does not currently have a designated lead independent director. We are aware of the potential conflicts that may arise when a non-independent director is chairman of the board of directors, but believe these potential conflicts are offset by our strong corporate governance policies. Our corporate governance policies include regular meetings of the independent directors in executive session without the presence of interested directors and management, the establishment of the Audit Committee, the Nominating and Corporate Governance Committee, and the Compensation Committee, which are comprised solely of independent directors and the appointment of a chief compliance officer, with whom the independent directors meet regularly without the presence of interested directors and other members of management, for administering our compliance policies and procedures.

We recognize that different board leadership structures are appropriate for companies in different situations. We re-examine our corporate governance policies on an ongoing basis to ensure that they continue to meet Solar Senior Capital’s needs.

Board’s Role in Risk Oversight

Our board of directors performs its risk oversight function primarily through (a) its three standing committees, which report to the entire board of directors and are comprised solely of independent directors, and (b) active monitoring of our Chief Compliance Officer and our compliance policies and procedures.

As described below in more detail under “Committees of the Board of Directors,” the audit committee, the nominating and corporate governance committee and the compensation committee assist the board of directors in fulfilling its risk oversight responsibilities. The audit committee’s risk oversight responsibilities include overseeing Solar Senior Capital’s accounting and financial reporting processes, Solar Senior Capital’s systems of internal controls regarding finance and accounting, and audits of Solar Senior Capital’s financial statements. The nominating and corporate governance committee’s risk oversight responsibilities include selecting, researching

12

and nominating directors for election by our stockholders, developing and recommending to the board of directors a set of corporate governance principles and overseeing the evaluation of the board of directors and our management. The compensation committee’s risk oversight responsibilities include reviewing and recommending to our board of directors for approval the First Amended and Restated Investment Advisory and Management Agreement (the “Advisory Agreement”), between the Company and Solar Capital Partners and the Amended and Restated Administration Agreement (the “Administration Agreement”), between the Company and the Solar Capital Management, and, to the extent that we compensate our executive officers directly in the future, reviewing and evaluating the compensation of our executive officers and making recommendations to the board of directors regarding such compensation.

Our board of directors also performs its risk oversight responsibilities with the assistance of the Chief Compliance Officer. The board of directors annually reviews a written report from the Chief Compliance Officer discussing the adequacy and effectiveness of the compliance policies and procedures of Solar Senior Capital and its service providers. The Chief Compliance Officer’s annual report addresses at a minimum (a) the operation of the compliance policies and procedures of Solar Senior Capital and its service providers since the last report; (b) any material changes to such policies and procedures since the last report; (c) any recommendations for material changes to such policies and procedures as a result of the Chief Compliance Officer’s annual review; and (d) any compliance matter that has occurred since the date of the last report about which the board of directors would reasonably need to know to oversee our compliance activities and risks. In addition, the Chief Compliance Officer meets separately in executive session with the independent directors at least once each year.

We believe that our board’s role in risk oversight is effective and appropriate given the extensive regulation to which we are already subject as a BDC. As a BDC, we are required to comply with certain regulatory requirements that control the levels of risk in our business and operations. For example, our ability to incur indebtedness is limited such that our asset coverage must equal at least 200% immediately after each time we incur indebtedness, we generally cannot invest in assets that are not “qualifying assets” unless at least 70% of our total assets consist of “qualifying assets” immediately prior to such investment, and we are not generally permitted to invest, subject to certain exceptions, in any portfolio company in which one of our affiliates currently has an investment.

We recognize that different board of directors’ roles in risk oversight are appropriate for companies in different situations. We re-examine the manners in which the board of directors administers its oversight function on an ongoing basis to ensure that they continue to meet Solar Senior Capital’s needs.

Committees of the Board of Directors

An Audit Committee, a Nominating and Corporate Governance Committee and a Compensation Committee have been established by our board of directors. During 2017, our board of directors held five Board of Directors meetings, five Audit Committee meetings, two Nominating and Corporate Governance Committee meetings and one Compensation Committee meeting. During 2017, all directors attended at least 75% of the aggregate number of meetings of the board of directors and of the respective committees on which they serve. We require each director to make a diligent effort to attend all board of director and committee meetings as well as encourage attendance at each annual meeting of our stockholders. Two of our directors attended the 2017 annual meeting of stockholders in person.

Audit Committee. The Audit Committee operates pursuant to a charter approved by our board of directors, a copy of which is available on our website at http://www.solarseniorcap.com. The charter sets forth the responsibilities of the Audit Committee. The Audit Committee’s responsibilities include selecting the independent registered public accounting firm for the Company, reviewing with such independent registered public accounting firm the planning, scope and results of their audit of the Company’s financial statements, pre-approving the fees for services performed, reviewing with the independent registered public accounting firm the adequacy of internal control systems, reviewing the Company’s annual financial statements and periodic

13

filings and receiving the Company’s audit reports and financial statements. The Audit Committee also establishes guidelines and makes recommendations to our board of directors regarding the valuation of our investments. The Audit Committee is responsible for aiding our board of directors in determining the fair value of debt and equity securities that are not publicly traded or for which current market values are not readily available. The Board of Directors and Audit Committee utilize the services of nationally recognized third-party valuation firms to help determine the fair value of these securities. The Audit Committee is currently composed of Messrs. Hochberg, Wachter and Potter, all of whom are considered independent under the rules of the NASDAQ Stock Market and are not “interested persons” of the Company as that term is defined in Section 2(a)(19) of the 1940 Act. Mr. Hochberg serves as Chairman of the Audit Committee. Our board of directors has determined that Mr. Hochberg is an “audit committee financial expert” as that term is defined under Item 407 of Regulation S-K, as promulgated under the Exchange Act. Mr. Hochberg meets the current independence and experience requirements of Rule 10A-3 of the Exchange Act.

Nominating and Corporate Governance Committee. The Nominating and Corporate Governance Committee operates pursuant to a charter approved by our board of directors, a copy of which is available on our website at http://www.solarseniorcap.com. The members of the Nominating and Corporate Governance Committee are Messrs. Hochberg, Wachter and Potter, all of whom are considered independent under the rules of the NASDAQ Stock Market and are not “interested persons” of the Company as that term is defined in Section 2(a)(19) of the 1940 Act. Mr. Wachter serves as Chairman of the Nominating and Corporate Governance Committee. The Nominating and Corporate Governance Committee is responsible for selecting, researching and nominating directors for election by our stockholders, selecting nominees to fill vacancies on the board of directors or a committee thereof, developing and recommending to the board of directors a set of corporate governance principles and overseeing the evaluation of the board of directors and our management. The Nominating and Corporate Governance Committee currently does not consider nominees recommended by our stockholders.

The Nominating and Corporate Governance committee seeks candidates who possess the background, skills and expertise to make a significant contribution to the board of directors, the Company and its stockholders. In considering possible candidates for election as a director, the Nominating and Corporate Governance Committee takes into account, in addition to such other factors as it deems relevant, the desirability of selecting directors who:

The Nominating and Corporate Governance Committee has not adopted a formal policy with regard to the consideration of diversity in identifying director nominees. In determining whether to recommend a director nominee, the Nominating and Corporate Governance Committee considers and discusses diversity, among other factors, with a view toward the needs of the board of directors as a whole. The Nominating and Corporate Governance Committee generally conceptualizes diversity expansively to include, without limitation, concepts such as race, gender, national origin, differences of viewpoint, professional experience, education, skill and other qualities that contribute to the board of directors, when identifying and recommending director nominees. The Nominating and Corporate Governance Committee believes that the inclusion of diversity as one of many factors considered in selecting director nominees is consistent with the Nominating and Corporate Governance Committee’s goal of creating a board of directors that best serves the needs of Solar Senior Capital and the interest of its stockholders.

14

Compensation Committee. The Compensation Committee operates pursuant to a charter approved by our board of directors, a copy of which is available on our website at http://www.solarseniorcap.com. The charter sets forth the responsibilities of the Compensation Committee. The Compensation Committee is responsible for reviewing and recommending for approval to our board of directors the Advisory Agreement and the Administration Agreement. In addition, although we do not directly compensate our executive officers currently, to the extent that we do so in the future, the Compensation Committee would also be responsible for reviewing and evaluating their compensation and making recommendations to the board of directors regarding their compensation. Lastly, the compensation committee would produce a report on our executive compensation practices and policies for inclusion in our proxy statement if required by applicable proxy rules and regulations and, if applicable, make recommendations to the board of directors on matters related to compensation generally. The Compensation Committee has the authority to engage compensation consultants and to delegate their duties and responsibilities to a member or to a subcommittee of the Compensation Committee. The members of the Compensation Committee are Messrs. Hochberg, Wachter and Potter, all of whom are considered independent under the rules of the NASDAQ Stock Market and are not “interested persons” of the Company as that term is defined in Section 2(a)(19) of the 1940 Act. Mr. Potter serves as Chairman of the Compensation Committee.

Code of Ethics

The Company has adopted a code of ethics that applies to, among others, its senior officers, including its Chief Executive Officer and its Chief Financial Officer, as well as every officer, director and employee of the Company.

The Company intends to disclose amendments to or waivers from a required provision of the code of ethics on Form 8-K.

Compensation of Directors

The following table sets forth compensation of the Company’s directors, for the year ended December 31, 2017.

15

Our independent directors’ annual fee is $50,000. The independent directors also receive $1,250 ($500 if participating telephonically) plus reimbursement of reasonable out-of-pocket expenses incurred in connection with attending each board meeting and $500 plus reimbursement of reasonable out-of-pocket expenses incurred in connection with each committee meeting attended. In addition, the Chairman of the Audit Committee receives an annual fee of $3,750, the Chairman of the Nominating and Corporate Governance Committee receives an annual fee of $1,250 and the Chairman of the Compensation Committee receives an annual fee of $1,250. Further, we purchase directors’ and officers’ liability insurance on behalf of our directors and officers. In addition, no compensation was paid to directors who are interested persons of the Company as defined in the 1940 Act.

Compensation of Executive Officers

None of our officers receives direct compensation from the Company. As a result, we do not engage any compensation consultants. Mr. Gross, our Chief Executive Officer and President, and Mr. Spohler, our Chief Operating Officer, through their ownership interest in Solar Capital Partners, our investment adviser, are entitled to a portion of any profits earned by Solar Capital Partners, which includes any fees payable by us to Solar Capital Partners under the terms of the Advisory Agreement, less expenses incurred by Solar Capital Partners in performing its services under the Advisory Agreement. Messrs. Gross and Spohler do not receive any additional compensation from Solar Capital Partners in connection with the management of our portfolio.

Mr. Peteka, our Chief Financial Officer, Treasurer and Secretary and, through Alaric Compliance Services, LLC, Guy Talarico, our Chief Compliance Officer, are paid by Solar Capital Management, our administrator, subject to reimbursement by us of an allocable portion of such compensation for services rendered by such persons to the Company. To the extent that Solar Capital Management outsources any of its functions, we will pay the fees associated with such functions on a direct basis without profit to Solar Capital Management.

Indemnification Agreements

We have entered into indemnification agreements with our directors. The indemnification agreements are intended to provide our directors the maximum indemnification permitted under Maryland law and the 1940 Act. Each indemnification agreement provides that Solar Senior Capital shall indemnify the director who is a party to the agreement (an “Indemnitee”), including the advancement of legal expenses, if, by reason of his or her corporate status, the Indemnitee is, or is threatened to be, made a party to or a witness in any threatened, pending, or completed proceeding, to the maximum extent permitted by Maryland law and the 1940 Act.

Certain Relationships and Transactions

We have entered into the Advisory Agreement with Solar Capital Partners. Mr. Gross, our Chairman, Chief Executive Officer and President, and Mr. Spohler, our Chief Operating Officer and board member, are managing members and senior investment professionals of, and have financial and controlling interests in, Solar Capital Partners. In addition, Mr. Peteka, our Chief Financial Officer, Treasurer and Secretary, serves as the Chief Financial Officer for Solar Capital Partners.

Solar Capital Partners and its affiliates may also manage other funds in the future that may have investment mandates that are similar, in whole and in part, with ours. For example, Solar Capital Partners presently serves as investment adviser to Solar Capital Ltd., a publicly traded BDC, which focuses on investing primarily in senior secured loans, mezzanine loans and equity securities. In addition, Michael S. Gross, our Chairman and Chief Executive Officer, Bruce Spohler, our Chief Operating Officer, and Richard L. Peteka, our Chief Financial Officer, serve in similar capacities for Solar Capital Ltd.

Solar Capital Partners and certain investment advisory affiliates may determine that an investment is appropriate for us and for one or more of those other funds. In such event, depending on the availability of such

16

investment and other appropriate factors, Solar Capital Partners or its affiliates may determine that we should invest side-by-side with one or more other funds. Any such investments will be made only to the extent permitted by applicable law and interpretive positions of the SEC and its staff, and consistent with Solar Capital Partners’ allocation procedures.

Related party transactions may occur among Solar Senior Capital Ltd. and Gemino Healthcare Finance, LLC, First Lien Loan Program LLC, NorthMill LLC and FLLP 2015-1, LLC. These transactions may occur in the normal course of business. No administrative fees are paid to Solar Capital Partners by Gemino Healthcare Finance, LLC, NorthMill LLC or First Lien Loan Program LLC.

In addition, we have adopted a formal code of ethics that governs the conduct of our officers and directors. Our officers and directors also remain subject to the duties imposed by both the 1940 Act and the Maryland General Corporation Law.

Regulatory restrictions limit our ability to invest in any portfolio company in which any affiliate currently has an investment. The Company obtained an exemptive order from the SEC on July 28, 2014 (the “Exemptive Order”). The Exemptive Order permitted us to participate in negotiated co-investment transactions with certain affiliates, each of whose investment adviser is Solar Capital Partners, in a manner consistent with our investment objective, positions, policies, strategies and restrictions as well as regulatory requirements and other pertinent factors, and pursuant to the conditions to the Exemptive Order. On June 13, 2017, the Company, Solar Capital Ltd., and Solar Capital Partners received an exemptive order that supersedes the Exemptive Order (the “New Exemptive Order”) and extends the relief granted in the Exemptive Order such that it no longer applies to certain affiliates only if their respective investment adviser is Solar Capital Partners, but also applies to certain affiliates whose investment adviser is an investment adviser that controls, is controlled by or is under common control with Solar Capital Partners and is registered as an investment adviser under the Investment Advisers Act of 1940, as amended. The terms and conditions of the New Exemptive Order are otherwise substantially similar to the Exemptive Order. We believe that it will be advantageous for us to co-invest with funds managed by Solar Capital Partners where such investment is consistent with the investment objectives, investment positions, investment policies, investment strategy, investment restrictions, regulatory requirements and other pertinent factors applicable to us.

We have entered into a license agreement with Solar Capital Partners, pursuant to which Solar Capital Partners has agreed to grant us a non-exclusive, royalty-free license to use the name “Solar Senior Capital.” In addition, pursuant to the terms of the Administration Agreement, Solar Capital Management provides us with the office facilities and administrative services necessary to conduct our day-to-day operations.

Board Consideration of the Investment Advisory and Management Agreement

Our board of directors determined at a meeting held on November 2, 2017, to re-approve the Advisory Agreement between the Company and Solar Capital Partners. In its consideration of the re-approval of the Advisory Agreement, the board of directors focused on information it had received relating to, among other things:

17

Based on the information reviewed and the discussions detailed above, the board of directors, including a majority of the directors who are not “interested persons” as defined in the 1940 Act, concluded that the fees payable to Solar Capital Partners pursuant to the Advisory Agreement were reasonable, and comparable to the fees paid by other management investment companies with similar investment objectives, in relation to the services to be provided. The board of directors did not assign relative weights to the above factors or the other factors considered by it. Individual members of the board of directors may have given different weights to different factors.

Section 16(a) Beneficial Ownership Reporting Compliance

Pursuant to Section 16(a) of the Exchange Act, the Company’s directors and executive officers, and any persons holding more than 10% of its common stock, are required to report their beneficial ownership and any changes therein to the SEC and the Company. Specific due dates for those reports have been established, and the Company is required to report herein any failure to file such reports by those due dates. Based solely on a review of copies of such reports and written representations delivered to the Company by such persons, the Company believes that there were no violations of Section 16(a) by such persons during the fiscal year ended December 31, 2017.

Independent Registered Public Accounting Firm

The Audit Committee and the independent directors of the board of directors have selected KPMG LLP to serve as the independent registered public accounting firm for the Company for the fiscal year ending December 31, 2018.

KPMG LLP has advised us that neither the firm nor any present member or associate of it has any material financial interest, direct or indirect, in the Company or its affiliates. It is expected that a representative of KPMG LLP will be present at the Meeting and will have an opportunity to make a statement if he or she chooses and will be available to answer questions.

Audit Committee Report

The Audit Committee of our board of directors operates under a written charter adopted by the board of directors. The Audit Committee is currently composed of Messrs. Hochberg, Wachter and Potter.

Management is responsible for the Company’s internal controls and the financial reporting process. The Company’s independent registered public accounting firm is responsible for performing an independent audit of the Company’s financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States) and expressing an opinion in conformity with U.S. generally accepted accounting principles. The Audit Committee’s responsibility is to monitor and oversee these processes. The Audit Committee is also directly responsible for the appointment, compensation and oversight of the Company’s independent registered public accounting firm.

Pre-Approval Policy

The Audit Committee has established a pre-approval policy that describes the permitted audit, audit-related, tax and other services to be provided by KPMG LLP, the Company’s independent registered public accounting firm (“KPMG”). The policy requires that the Audit Committee pre-approve the audit and non-audit services performed by the independent auditor in order to assure that the provision of such service does not impair the auditor’s independence.

Any requests for audit, audit-related, tax and other services that have not received general pre-approval must be submitted to the Audit Committee for specific pre-approval, irrespective of the amount, and cannot commence until such approval has been granted. Normally, pre-approval is provided at regularly scheduled meetings of the Audit Committee. However, the Audit Committee may delegate pre-approval authority to one or more of its

19

members. The member or members to whom such authority is delegated shall report any pre-approval decisions to the Audit Committee at its next scheduled meeting. The Audit Committee does not delegate its responsibilities to pre-approve services performed by the independent registered public accounting firm to management. The Audit Committee pre-approved 100% of services described in this policy.

Review with Management

The Audit Committee has reviewed the audited financial statements and met and held discussions with management regarding the audited financial statements. Management has represented to the Audit Committee that the Company’s financial statements were prepared in accordance with the standards of the Public Company Accounting Oversight Board (United States).

Review and Discussion with Independent Registered Public Accounting Firm

The Audit Committee has reviewed and discussed the Company’s audited financial statements with management and KPMG, with and without management present. The Audit Committee included in its review results of KPMG’s examinations, the Company’s internal controls, and the quality of the Company’s financial reporting. The Audit Committee also reviewed the Company’s procedures and internal control processes designed to ensure full, fair and adequate financial reporting and disclosures, including procedures for certifications by the Company’s Chief Executive Officer and Chief Financial Officer that are required in periodic reports filed by the Company with the SEC. The Audit Committee is satisfied that the Company’s internal control system is adequate and that the Company employs appropriate accounting and auditing procedures.

The Audit Committee also has discussed with KPMG matters relating to KPMG’s assessment about the quality, as well as the acceptability, of the Company’s accounting principles as applied in its financial reporting as required by PCAOB Auditing Standard 16 (Communications with Audit Committees). In addition, the Audit Committee has discussed with KPMG their independence from management and the Company, as well as the matters in the written disclosures received from KPMG and required by Public Company Accounting Oversight Board Rule 3520 (Auditor Independence). The Audit Committee received a letter from KPMG confirming their independence and discussed it with them. The Audit Committee discussed and reviewed with KPMG the Company’s critical accounting policies and practices, internal controls, other material written communications to management, and the scope of KPMG’s audits and all fees paid to KPMG during the fiscal year. The Audit Committee has adopted guidelines requiring review and pre-approval by the Audit Committee of audit and non-audit services performed by KPMG for the Company. The Audit Committee has reviewed and considered the compatibility of KPMG’s performance of non-audit services with the maintenance of KPMG’s independence as the Company’s independent registered public accounting firm.

20

Conclusion

Based on the Audit Committee’s discussion with management and the independent registered public accounting firm, the Audit Committee’s review of the audited financial statements, the representations of management and the report of the independent registered public accounting firm to the Audit Committee, the Audit Committee recommended that the board of directors include the audited financial statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017 for filing with the SEC. The Audit Committee also recommended the selection of KPMG to serve as the independent registered public accounting firm for the year ending December 31, 2018.

The material contained in the foregoing Audit Committee Report is not “soliciting material,” is not deemed “filed” with the SEC, and is not to be incorporated by reference into any filing of the Company under the Securities Act of 1933, as amended, or the Exchange Act, whether made before or after the date hereof and irrespective of any general incorporation language in any such filing.

PROPOSAL II:

APPROVAL TO AUTHORIZE THE COMPANY TO SELL SHARES OF ITS COMMON STOCK AT A PRICE OR PRICES BELOW THE COMPANY’S THEN CURRENT NET ASSET VALUE PER SHARE IN ONE OR MORE OFFERINGS, IN EACH CASE SUBJECT TO THE APPROVAL OF ITS BOARD OF DIRECTORS AND COMPLIANCE WITH THE CONDITIONS SET FORTH IN THE PROXY STATEMENT.

The Company is a closed-end investment company that has elected to be regulated as a BDC under the 1940 Act. The 1940 Act prohibits the Company from selling shares of its common stock at a price below the then current net asset value (“NAV”) per share of such stock, exclusive of sales compensation, unless its stockholders approve such a sale and the Company’s board of directors make certain determinations. Shares of the Company’s common stock have traded at a price both above and below their NAV since they have begun trading on the NASDAQ Global Select Market.

Pursuant to this provision, the Company is seeking the approval of its common stockholders so that it may, in one or more public or private offerings of its common stock, sell or otherwise issue shares of its common stock, not exceeding 25% of its then outstanding common stock immediately prior to each such offering, at a price below its then current NAV, subject to certain conditions discussed below. The Company’s board of directors believes that having the flexibility for the Company to sell its common stock below NAV in certain instances is in the best interests of stockholders. If the Company were unable to access the capital markets as attractive investment opportunities arise, the Company’s ability to grow over time and continue to pay distributions to stockholders could be adversely affected.

While the Company has no immediate plans to sell shares of its common stock below NAV, it is seeking stockholder approval now in order to maintain access to the markets if the Company determines it should sell shares of common stock below NAV. These sales typically must be undertaken quickly. The final terms of any such sale will be determined by the board of directors at the time of sale. Also, because the Company has no immediate plans to sell any shares of its common stock, it is impracticable to describe the transaction or transactions in which such shares of common stock would be sold. Instead, any transaction where the Company sells such shares of common stock, including the nature and amount of consideration that would be received by the Company at the time of sale and the use of any such consideration, will be reviewed and approved by the board of directors at the time of sale. There will be no limit on the percentage below NAV per share at which shares may be sold by the Company under this proposal. However, the Company does not presently intend to sell shares of its common stock at a price that is more than 20% lower than the Company’s then current NAV, absent extenuating circumstances, including, but not limited to, circumstances that would require the Company to raise equity capital in order to avoid defaulting on its debt obligations. If this proposal is approved, no further authorization from the stockholders will be solicited prior to any such sale in accordance with the terms of this proposal. If approved, as required under the 1940 Act, the authorization would be effective for securities sold during a period beginning on the date of such stockholder approval and expiring on the earlier of the anniversary of the date of the Meeting or the date of the Company’s 2019 Annual Meeting of Stockholders. Stockholders approved similar proposals at the 2012, 2013, 2014, 2015, 2016 and 2017 Annual Meetings of Stockholders. However, notwithstanding such stockholder approvals, since the Company’s initial public offering on February 24, 2011, the Company has not sold any shares of its common stock in an offering that resulted in proceeds to the Company of less than the Company’s then current NAV per share.

Generally, common stock offerings by BDCs are priced based on the market price of the currently outstanding shares of common stock, less a small discount of approximately 5% (which may be higher or lower depending on market conditions), which means that such offerings are generally priced below the then current market price of the BDC’s common stock. Accordingly, even when shares of the Company’s common stock trade at a market price below NAV, this proposal would permit the Company to offer and sell shares of its common stock in accordance with pricing standards that market conditions generally require, subject to the conditions described below in connection with any offering undertaken pursuant to this proposal. This Proxy

22

Statement is not an offer to sell securities. Securities may not be offered or sold in the United States absent registration with the SEC or an applicable exemption from SEC registration requirements.

1940 Act Conditions for Sales below NAV

The Company’s ability to issue shares of its common stock at a price below NAV is governed by the 1940 Act. If stockholders approve this proposal, the Company will only sell shares of its common stock at a price below NAV per share if the following conditions are met:

Board Approval

On February 22, 2018, our board of directors, including a majority of the non-interested directors who have no financial interest in this proposal, approved this proposal as in the best interests of the Company and its stockholders and is recommending that the Company’s stockholders vote in favor of this proposal to offer and sell shares of the Company’s common stock at prices that may be less than NAV. In evaluating this proposal, our board of directors, including the non-interested directors, considered and evaluated factors including the following, as discussed more fully below:

Prior to approving this proposal, our board of directors met to consider and evaluate information that our management provided on the merits of our possibly raising additional capital and the merits of publicly offering shares of the Company’s common stock at a price below NAV. Our board of directors considered the objectives of a possible offering, the mechanics of an offering, establishing size parameters for an offering, the possible effects of dilution, common stock trading volume, and other matters, including that the Company’s common stock has frequently traded both above and below NAV in recent years. The board of directors evaluated a full range of offering sizes. However, the board of directors has not yet drawn any definite conclusions regarding the size of a contemplated capital raise at this time, to the extent the Company’s common stock were to trade below NAV. In determining whether or not to offer and sell common stock, including below NAV, the board of directors has a duty to act in the Company’s best interests and its stockholders and must comply with the other requirements of the 1940 Act.

Reasons to Offer Common Stock below NAV

The Company’s board of directors believes that having the flexibility for the Company to sell its common stock below NAV in certain instances is in the Company’s best interests and the best interests of its stockholders. If the Company were unable to access the capital markets when attractive investment opportunities arise, the Company’s ability to grow over time and to continue to pay distributions to stockholders could be adversely

23

affected. In reaching that conclusion, the Company’s board of directors considered the following possible benefits to its stockholders:

Current Market Conditions Have Attractive Opportunities

Current market opportunities have created, and we believe will continue to create for the foreseeable future, favorable opportunities to invest, including opportunities that, all else being equal, may increase the Company’s NAV over the longer-term, even if financed with the issuance of common stock below NAV. Stockholder approval of this proposal, subject to the conditions detailed below, is expected to provide the Company with the flexibility to invest in such opportunities. We believe that current market conditions provide attractive opportunities to use capital.

Market conditions also have beneficial effects for capital providers, including reduced competition, more favorable pricing of credit risk, more conservative capital structures and more creditor-friendly contractual terms. Accordingly, we believe that the Company could benefit from access to capital in this constrained credit market and that the current environment should provide attractive investment opportunities. The Company’s ability to take advantage of these opportunities will depend upon its access to capital.

Greater Investment Opportunities Due to Larger Capital Resources

The Company’s board of directors believes that additional capital raised through an offering of shares of its common stock, even at a price below NAV, may help it generate additional deal flow. Based on discussions with management, the Company’s board of directors believes that greater deal flow, which may be achieved with more capital, even if such capital is obtained through the issuance of common stock below NAV, would enable the Company to be a more significant participant in the private debt and equity markets and to compete more effectively for attractive investment opportunities. Management has represented to the Company’s board of directors that such investment opportunities may be funded with proceeds of an offering of shares of the Company’s common stock at a price below NAV. However, management has not identified specific companies in which to invest the proceeds of an offering given that specific investment opportunities will change depending on the timing of an offering, if any.

Higher Market Capitalization and Liquidity May Make the Company’s Common Stock More Attractive to Investors

If the Company issues additional shares, its market capitalization and the amount of its publicly tradable common stock will increase, which may afford all holders of its common stock greater liquidity even if such additional liquidity is created through the issuance of shares below NAV. A larger market capitalization may make the Company’s stock more attractive to a larger number of investors who have limitations on the size of companies in which they invest. Furthermore, a larger number of shares outstanding may increase the Company’s trading volume, which could decrease the volatility in the secondary market price of its common stock.

Maintenance or Possible Increase of Distributions

A larger and more diversified portfolio could provide the Company with more consistent cash flow, which may support the maintenance and/or growth of its distributions. The Company generally makes distributions to its stockholders monthly and for the year ended December 31, 2017 the Company declared total distributions of $1.41 per share of its common stock. Although management will continue to seek to generate income sufficient to pay the Company’s distributions in the future, the proceeds of future offerings, and the investments thereof, could enable the Company to maintain and/or possibly grow its distributions, which may include a return of capital.

24

Reduced Expenses Per Share

An offering that increases the Company’s total assets may reduce its expenses per share due to the spreading of fixed expenses over a larger asset base. The Company must bear certain fixed expenses, such as certain administrative, governance and compliance costs that do not generally vary based on its size. On a per share basis, these fixed expenses will be reduced when supported by a larger asset base.

Status as a BDC and RIC and Maintaining a Favorable Debt-to-Equity Ratio

As a BDC and a regulated investment company (“RIC”) for tax purposes, the Company is dependent on its ability to raise capital through the sale of common stock. RICs generally must distribute substantially all of their earnings from dividends, interest and short-term gains to stockholders as distributions in order to achieve pass-through tax treatment, which prevents the Company from using those earnings to support new investments. Further, for the same reason BDCs, in order to borrow money or issue preferred stock, must maintain a debt to equity ratio of not more than 1:1, which requires the Company to finance its investments with at least as much common equity as debt and preferred stock in the aggregate. Therefore, to continue to build the Company’s investment portfolio, and thereby support maintenance and growth of the Company’s distributions, the Company endeavors to maintain consistent access to capital through the public and private equity markets enabling it to take advantage of investment opportunities as they arise.

Exceeding the required 1:1 debt-to-equity ratio would have severe negative consequences for a BDC, including an inability to pay distributions, possible breaches of debt covenants and failure to qualify for tax treatment as a RIC. Although the Company does not currently expect that it will exceed the required 1:1 debt-to-equity ratio, the markets the Company operates in and the general economy remain volatile and uncertain. Even though the underlying performance of a particular portfolio company may not indicate impairment or an inability to repay indebtedness in full, the volatility in the debt capital markets may continue to impact the valuations of debt investments negatively and result in further unrealized write-downs of debt investments. Any such asset write- downs, as well as unrealized write-downs based on the underlying performance of the Company’s portfolio companies, if any, will negatively impact its stockholders’ equity and the resulting debt-to-equity ratio. Issuing new equity will improve the Company’s debt-to-equity ratio. In addition to meeting legal requirements applicable to BDCs, having a more favorable debt-to-equity ratio will also generally strengthen the Company’s balance sheet and give it more flexibility in its operations.

25

Trading History

Shares of BDCs may trade at a market price that is less than the value of the net assets attributable to those shares. The possibility that the Company’s shares of common stock will trade at a discount from NAV, or at premiums that are unsustainable over the long term, are separate and distinct from the risk that the Company’s NAV will decrease. Since the Company’s initial public offering on February 24, 2011, its shares of common stock have traded at both a discount and a premium to the net assets attributable to those shares. As of March 27, 2018, the Company’s shares of common stock traded at a [discount/premium] equal to approximately [    ]% of the net assets attributable to those shares based upon its NAV as of December 31, 2017. It is not possible to predict whether the shares that may be offered pursuant to this approval will trade at, above, or below NAV. The following table lists the high and low closing prices for our common stock for each fiscal quarter since the beginning of 2016, such sales prices as a percentage of NAV per share and monthly distributions per share.

Key Stockholder Considerations and Risk Factors

Dilutive Effect on Net Asset Value

Before voting on this proposal or giving proxies with regard to this matter, stockholders should consider the dilutive effect of the issuance of shares of the Company’s common stock at a price that is less than the NAV per share and the expenses associated with such issuance on the NAV per outstanding share of the Company’s common stock. Any sale of common stock at a price below NAV would result in an immediate dilution to existing common stockholders. This dilution would include reduction in the NAV per share as a result of the issuance of shares at a price below the NAV per share and a disproportionately greater decrease in a current stockholder’s interest in the earnings and assets of the Company and voting interest in the Company than the increase in the assets of the Company resulting from such issuance. It would also decrease the amount of net investment income per share available to stockholders through distributions. There will be no limit on the percentage below NAV per share at which shares may be sold by the Company under this proposal. However, the

26

Company does not presently intend to sell shares of its common stock at a price that is more than 20% lower than the Company’s then current NAV, absent extenuating circumstances. The board of directors of the Company has considered the potential dilutive effect of the issuance of shares at a price below the NAV per share and will consider again such dilutive effect when considering whether to authorize any specific issuance of shares of common stock below NAV. The Company will not be required to obtain any additional authorization from stockholders for such offerings until the 2019 Annual Meeting of Stockholders even if the dilution from such offerings is substantial.

Dilutive Effect on Market Price and Ownership Percentage

In addition, stockholders should consider the risk that the approval of this proposal could cause the market price of the Company’s common stock to decline in anticipation of sales of its common stock below NAV, thus causing the Company’s shares to trade at a discount to NAV. The 1940 Act establishes a connection between common share sale price and NAV because, when stock is sold at a sale price below NAV per share, the resulting increase in the number of outstanding shares reduces NAV per share. Stockholders should also consider that they will have no subscription, preferential or preemptive rights to additional shares of the common stock proposed to be authorized for issuance, and thus any future issuance of common stock will dilute such stockholders’ holdings of common stock as a percentage of shares outstanding to the extent stockholders do not purchase sufficient shares in the offering or otherwise to maintain their percentage interest. Further, if current stockholders of the Company do not purchase any shares to maintain their percentage interest, regardless of whether such offering is above or below the then-current NAV, their voting power will be diluted.

Other Dilutive Considerations

The precise extent of any such dilution cannot be estimated before the terms of a common stock offering are set. As a general proposition, however, the amount of potential dilution will increase as the size of the offering increases. Another factor that will influence the amount of dilution in an offering is the amount of net proceeds that we receive from such offering. The board of directors would expect that the net proceeds to us, which is typically 95% of the market price, will be equal to the price that investors pay per share less the amount of any underwriting discounts and commissions.

As discussed above, it should be noted that the maximum number of shares issuable below NAV that could result in such dilution is limited to 25% of the Company’s then outstanding common stock immediately prior to each such offering. As a result, the maximum amount of dilution to existing stockholders will be limited to no more than 20% of the Company’s then current NAV on each offering, assuming the Company were to issue the maximum number of shares at no more than par value, or $0.01 per share. Subject to the aforementioned 25% limit that is determined prior to each offering, there is no theoretical limit on the number of times that the Company can offer its common stock below NAV during the year following the approval of this proposal.

Conflict of Interest

In reaching its recommendation to the stockholders of the Company to approve this proposal, the board of directors considered a possible source of conflict of interest due to the fact that the proceeds from the issuance of additional shares of the Company’s common stock may increase the management fees that the Company pays to Solar Capital Partners as such fees are partially based on the amount of the Company’s gross assets, as well as the effect of the following factors:

27

The board of directors, including a majority of the non-interested directors who have no financial interest in this proposal, concluded that the benefits to the stockholders from increasing the Company’s capital base outweighed any possible detriment, including from any possible increase in management fees or dilution to existing stockholders.

Examples of Dilutive Effect of the Issuance of Shares Below NAV

The following table illustrates the level of NAV dilution that would be experienced by a nonparticipating stockholder in four different hypothetical offerings of different sizes and levels of discount from NAV per share, although it is not possible to predict the level of market price decline that may occur. Actual sales prices and discounts may differ from the presentation below.

The examples assume that Company XYZ has 1,000,000 common shares outstanding, $15,000,000 in total assets and $5,000,000 in total liabilities. The current NAV and NAV per share are thus $10,000,000 and $10.00, respectively. The table illustrates the dilutive effect on nonparticipating Stockholder A of (1) an offering of 50,000 shares (5% of the outstanding shares) at $9.50 per share after underwriting discounts and commissions (a 5% discount from NAV); (2) an offering of 100,000 shares (10% of the outstanding shares) at $9.00 per share after underwriting discounts and commissions (a 10% discount from NAV); (3) an offering of 200,000 shares (20% of the outstanding shares) at $8.00 per share after underwriting discounts and commissions (a 20% discount from NAV); and (4) an offering of 250,000 shares (25% of the outstanding shares) at $0.01 per share after underwriting discounts and commissions (a 100% discount from NAV).

Potential Investors

The Company has not yet solicited any potential buyers of the shares that it may elect to issue in any future offering in order to comply with the federal securities laws. No shares are earmarked for management or other affiliated persons of the Company. However, members of management and other affiliated persons may participate in a common stock offering, if any, on the same terms as others.

Approval of this proposal requires the affirmative vote of (1) a majority of the outstanding voting securities as of the Record Date; and (2) a majority of the outstanding voting securities as of the Record Date that are not held by affiliated persons of the Company, which includes directors, officers, employees, and 5% stockholders. For purposes of this proposal, the 1940 Act defines “a majority of the outstanding voting securities” as: (1) 67% or more of the voting securities present at the Meeting if the holders of more than 50% of the outstanding voting securities of the Company are present or represented by proxy; or (2) 50% of the outstanding voting securities of the Company, whichever is less. Abstentions and broker non-votes will have the effect of a vote against this proposal.

THE BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE “FOR” THE PROPOSAL TO AUTHORIZE THE COMPANY TO SELL SHARES OF ITS COMMON STOCK AT A PRICE OR PRICES BELOW THE COMPANY’S THEN CURRENT NET ASSET VALUE PER SHARE IN ONE OR MORE OFFERINGS, IN EACH CASE SUBJECT TO THE APPROVAL OF ITS BOARD OF DIRECTORS AND COMPLIANCE WITH THE CONDITIONS SET FORTH IN THE PROXY STATEMENT.
