The American Stock Exchange has Approved the Listing of Common Stock of American
CareSource Holdings, Inc.

DALLAS, TX--(BUSINESS WIRE)--October 16, 2006-- American CareSource Holdings,
Inc. ("American CareSource"), a healthcare services company, today announced
that its shares of common stock have been approved for listing on the American
Stock Exchange (the "Exchange") based upon a review by an Exchange Listing
Qualifications Panel (the "Panel") which authorized approval of the listing
pursuant to Section 1203(c) of the American Stock Exchange Company Guide,
notwithstanding the fact that American CareSource does not fully satisfy the
Exchange's regular Initial Listing Standard 2 because its stock price has been
trading at less than $3.00. This approval is contingent upon American CareSource
being in compliance with all applicable listing standards on the date it begins
trading on the Exchange, and may be rescinded if American CareSource is not in
compliance with such standards on such date. The Panel's decision was based upon
its determination that American CareSource satisfies the minimum Alternative
Listing Standard B and its affirmative finding that the following mitigating
factors warrant listing pursuant to the Alternative Listing Standards: (1)
American CareSource's recent trends of growing revenues and declining losses,
(2) the health care industry experience of American CareSource's Board of
Directors and management, (3) American CareSource's particular niche in the
health care market, particularly ancillary benefits management, and (4) the
availability of capital to support American CareSource's plans.

company, is a comprehensive ancillary care service provider offering a national
