Exhibit 99.1

HMS Income Fund, Inc. Declares Third Quarter Distributions and extends Conditional Fee Waiver Agreement

HOUSTON, TX, June 28, 2013 - The board of directors of HMS Income Fund, Inc. ("HMS Income Fund") recently declared distributions for the months of July – September 2013 in the amount of $0.00191781 per share, per day (which represents an annualized distribution rate of 7.00% based on HMS Income’s current $10.00 per share public offering price, if it were maintained everyday for a twelve-month period). Distributions will be paid on the first business day following the completion of each month to which they relate. All distributions will be paid in cash or reinvested in stock for those participating in the distribution reinvestment plan. 

On June 28, 2013, HMS Income Fund entered into an amendment to the amended and restated conditional fee waiver agreement with HMS Adviser LP, Main Street Capital Corporation and Main Street Capital Partners, LLC (collectively, the “Advisers”), whereby the Advisers have agreed to extend the fee waiver period through December 31, 2013 to allow the Advisers to waive fees upon the occurrence of any event, which in the Advisers’ sole discretion is deemed necessary, including, but neither limited to nor automatically triggered by, HMS Income Fund’s estimate that a distribution declared and payable to its stockholders during the fee waiver period represents, or would represent when paid, a return of capital for U.S. federal income tax purposes. The Advisers have no obligation to waive fees pursuant to the conditional fee waiver agreement after December 31, 2013, unless the fee waiver period is further extended.

Certain Information About Distributions

The determination of the tax attributes of HMS Income Fund’s distributions will be made annually as of the end of HMS Income Fund’s fiscal year based upon its taxable income and distributions paid, in each case, for the full year. Therefore, a determination as to the tax attributes of the distributions made on a quarterly basis may not be representative of the actual tax attributes for a full year. The actual tax characteristics of distributions to stockholders will be reported to stockholders annually on a Form 1099-DIV. The payment of future distributions on HMS Income Fund’s common stock is subject to the discretion of the Board and applicable legal restrictions, and therefore, there can be no assurance as to the amount or timing of any such future distributions.

Such statements are based on current expectations and assumptions with respect to, among other things, future economic, competitive and market conditions and future business decisions that may prove incorrect or inaccurate.  Certain factors could cause actual results to differ materially from those projected in these forward-looking statements and some of these factors are enumerated in the filings HMS Income Fund makes with the Securities and Exchange Commission. HMS Income Fund undertakes no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise.
