Item 8.01. Other Events.

On June 1, 2006, Gladstone Capital Corporation announced that its offer to amend
the terms of all stock options currently outstanding (the "Options") under the
Company's Amended and Restated 2001 Equity Incentive Plan, as amended, to
accelerate the expiration date of the Options to September 30, 2006 (the
"Offer") has been accepted. The Offer was made to the executive officers and
directors of the Company and the employees of the Company's external investment
adviser, Gladstone Management Corporation, who hold stock options (the
"Optionees"), and was conditional upon its acceptance by all of the Optionees.
All Optionees accepted the Offer prior to its expiration on May 31, 2006. The
Offer is more fully described in the Schedule TO and related documentation filed
by the Company with the Securities and Exchange Commission on April 12, 2006.

On April 11, 2006, the Company's Board of Directors accelerated in full the
vesting of all outstanding options other than options held by the Company's
non-employee Directors. Following the acceptance of the Offer, all Options must
be either exercised or terminated prior to September 30, 2006.

The Company intends to implement, effective October 1, 2006, the proposed
Investment Advisory and Management Agreement between the Company and Gladstone
Management Corporation and the Administration Agreement between the Company and
Gladstone Administration, LLC, a wholly owned subsidiary of Gladstone Management
Corporation, which was approved by the Company's stockholders on December 2,
2005.
