At the Special Meeting, our stockholders will be asked to consider, among other things, a proposal to approve an amendment to our Certificate of Incorporation to increase our authorized capital stock so that we may complete our acquisition ("Acquisition") of substantially all of the assets of American CareSource Corporation ("ACS"). Stockholders should carefully review this Supplement and the Proxy Statement. The information in this Supplement replaces any inconsistent information in the Proxy Statement. You can vote your shares by completing and returning the proxy card included with your Proxy Statement. You can revoke a proxy at any time prior to its exercise at the adjourned Special Meeting by following the instructions in the Proxy Statement. Recent Developments ACS has received written notification of the termination of contractual relations from Pinnacol Assurance, which is the largest volume provider to ACS. The termination of this contract will result in a significant reduction in ACS' revenues. ACS' revenues from Pinnacol Assurance was as follows during the years ended December 31, 2001 and 2002, respectively, and during the six months ended June 30, 2003: Year Ended Year Ended Six Months Ended December 31, 2001 December 31, 2002 June 30, 2003 ---------------- ------------- ------------- ------------- ------------- ------------- Percentage of Percentage of Percentage of Amount Total Revenue Amount Total Revenue Amount Total Revenue ---------------- ------------- ------------- ------------- ------------- ------------- $1,163,041 45.7% $2,786,409 28.9% $1,936,799 40.5% ACS has a limited number of customers, a few of which account for a substantial portion of its business. During the last six months, ACS has received notice of the termination of contracts from customers representing in excess of 56% of ACS' revenues during the six months ended June 30, 2003. During the last six months, ACS has received written notification of the termination of contractual relations from Pinnacol Assurance and two of its other customers which in the aggregate accounted for over 51% of ACS' revenues during the fiscal year ended December 31, 2002 and accounted for over 56% of ACS' revenues during the six months ended June 30, 2003. The termination of these contracts will result in a significant reduction of ACS' revenues. Although a variety of reasons may be provided for the termination of each of the customer agreements, the termination of such an extensive amount of customer business may reflect a substantial level of customer dissatisfaction with the services provided by ACS. Although Patient Infosystems believes that it can provide assistance to ACS and that as a combined company, ACS will be able to provide better services, no assurance can be given that more customers will not terminate their relationships with ACS following the closing of the Acquisition. In addition, ACS generally does not have long-term contracts with its other customers. Significant declines in the level of use of ACS services by one or more of its remaining customers could have a material adverse effect on ACS' business and results of operations. Additionally, an adverse change in the financial condition of any of these customers, including an adverse change as a result of a change in governmental or private reimbursement programs, could have a material adverse effect on its business. Decrease in Number of Shares to be Issued to ACS As consideration for substantially all of ACS' assets, we had agreed to issue 18,000,000 shares of our common stock to ACS (1,500,000 shares after giving effect to the 1 for 12 reverse stock split which is also discussed in the Proxy Statement). As a result of, among other things, the recent developments disclosed above, we have agreed with ACS that we will issue only 13,200,000 shares of our common stock (1,100,000 shares after giving effect to the 1 for 12 reverse stock split) to ACS upon closing of the Acquisition. To the extent that fewer shares of our common stock will be issued, there will be a corresponding decrease in total stockholders' equity. In reviewing the information provided in the Proxy Statement, stockholders should consider the decrease in consideration provided to ACS and the corresponding reduction in pro forma total stockholders' equity from $1,919,014 to $1,247,014 as a result of the reduction in the purchase consideration.
