June 13, 2011

Dear Horizon Technology Finance Corporation Stockholder:

     We have previously mailed to you proxy materials, including a Proxy Statement dated June 1, 2011, in connection with the Special Meeting of Stockholders of Horizon Technology Finance Corporation (the “Company”) to be held at 10:00 a.m. on July 12, 2011 at the offices of the Company located at 312 Farmington Avenue, Farmington, Connecticut 06032 (the “Meeting”). Your vote is important and your participation is requested at this important Meeting.

     At the Meeting, you will be asked to approve a proposal to authorize flexibility for the Company, with the approval of its Board of Directors, to sell shares of its common stock (during the next 12 months) at a price below the then current net asset value per share in one or more offerings, subject to certain conditions as set forth in the Proxy Statement.

     THE BOARD OF DIRECTORS, INCLUDING THE INDEPENDENT DIRECTORS, UNANIMOUSLY RECOMMENDS THAT YOU VOTE “FOR” THE PROPOSAL.

     Your vote is very important. Approval of the Proposal requires the affirmative vote of the stockholders of the Company holding (1) a majority of the outstanding shares of the common stock of the Company entitled to vote at the Meeting and (2) a majority of the outstanding shares of the common stock of the Company entitled to vote at the Meeting that are not held by affiliated persons of the Company. Therefore, the vote of every stockholder is very important.

     If you do not give your broker or nominee specific instructions on how to vote for you or do not vote for yourself in accordance with the voting instructions on the proxy card contained in your proxy materials, by returning a proxy card or by other arrangement with your broker or nominee, your shares will be treated as not present at the Meeting and, as a result, will have no effect on the Company’s ability to obtain the approval of 67% or more of the voting securities present at the Meeting, but would have the same effect as a vote against the Proposal if the Company did not obtain the approval of 67% or more of the voting securities present and instead were seeking to obtain the affirmative vote of 50% of the outstanding voting securities of the Company.

     Please vote your proxy promptly without delay. Please submit your proxy in this important matter as promptly as possible (1) through the internet, (2) by marking, signing, and dating the enclosed proxy card or voting instruction form and returning it in the postage-paid return envelope provided, or (3) if you received a voting instruction form with telephonic instructions, by telephone.

     If you have any questions or need assistance voting your shares, please call D. F. King & Co., Inc., which is assisting us, toll-free at 1-800-800-487-4870.

     Thank you for your cooperation and continued support.

Sincerely,

Robert D. Pomeroy, Jr.
Chief Executive Officer
