American CareSource Holdings Signs Two New Client Agreements With Union Organizations in Midwest

American CareSource Holdings, Inc. (AMEX: XSI) announced today that it has signed new client service contracts with Iron Workers Local 295 Trust Fund, representing Iron Workers throughout the state of Indiana, and Operative Plasterers & Cement Masons Local 692, representing Plasterers and Mason Workers in Northwest Indiana. Both Local #395 and Local #692 are Taft-Hartley Health/Benefits Welfare Trust Funds.

Private sector unionized employees, including the building and construction trades, can obtain comprehensive health and other benefits through Taft-Hartley funds, also referred to as multiemployer plans. Taft-Hartley funds create economies of scale cost-savings because of their central administration and the pooling of resources. Under the two agreements, American CareSource will make available its full range of ancillary care services to each Union's member base through a network of ancillary care providers.

Commenting on today's news, David S. Boone, Chief Executive Officer of American CareSource, stated, "Winning these two new accounts represents another important milestone for the Company. We are extending our reach into the important union market in the Midwest. We are honored to have been chosen by these two important Indiana-based unions to provide their growing constituencies with value added, affordable ancillary healthcare benefits as an enhancement to their current programs. These agreements testify to the high-quality reputation of American CareSource and over time, we are looking forward to these new contracts paving the way for additional relationships with other key union organizations across the country."
