BOYNTON BEACH, Fla. and TAMPA BAY, Fla.--(BUSINESS WIRE)-- Jan. 19, 1999--Medical Industries of America, Inc. (Nasdaq:MIOA) and American Enterprise Solutions, Inc. (AESI) today jointly announced that the Companies have entered into a formal Letter of Intent to merge and will, upon completion of the merger, change its name.

Michael Morrell, Chief Executive Officer of MIOA said, "The merger with AESI will catapult the new combined company into the healthcare Internet business allowing MIOA to utilize the benefits of advanced Internet technologies to improve the quality of healthcare services while increasing profitability. The significant success that the Internet will provide to our healthcare companies and communities will finally start to reduce the unnecessary costs in the healthcare system and provide opportunities for additional profit centers that the Internet can bring. The merger will allow for the use of the Internet along with our new proprietary technologies to re-empower the patients and doctors in the management of their healthcare."

AESI is a Florida corporation that designs, develops, implements and operates Internet multi-media healthcare networks called "Community Health Information Utilities ("CHIUs"). These based utilities allow for the electronic connecting of all healthcare trading partners. These include doctors, hospitals, consumers, patients, employers, government agencies, managed care companies, insurance companies and all other providers and organizations. AESI also develops, manages and owns community healthcare delivery systems by incorporating and integrating all healthcare delivery services into a single-source delivery system. At the core of each enterprise is a CHIU.

The CHIU provides, over the Internet, clinical pathways and quality assurance applications and systems to maximize the flow of patient data and increase the ability of the physician, hospital, ancillary service and diagnostic center to service the patient. "The integration of the entire healthcare delivery system, through the use of the Company's technologies, creates substantial reductions in healthcare costs and provides improved profits over existing healthcare models," says Charles ("Chuck") Broes, Chief Executive Officer of AESI. Mr. Broes is a recognized healthcare visionary and believes that the development of the CHIU utilizing the Internet will be the formula for success by the healthcare industry in the 21st Century. Dr. Benedict Maniscalco, a leading cardiologist and one of the founders of AESI as well as its Chairman and visionary of the community healthcare enterprise model, is quoted as saying "until you re-empower the patient and physician, you can not deliver quality healthcare at the appropriate cost with measurable and meaningful outcomes."

The terms and conditions of the merger provide that MIOA and AESI shall be of equal value as of the time of closing. As a result, the shareholders of AESI will receive shares of common stock in MIOA equal to the number of shares of common stock held by the MIOA shareholders. The parties anticipate that, at the time of closing, the relative value of the MIOA shares will be $2.50 and that the merger will be subject to final negotiation, evaluation, execution of the merger agreement and shareholder and SEC approvals.

Initially, the merger will create revenues in excess of $100 million for the combined companies with unlimited growth potential. Michael Morrell will continue to serve MIOA as its Chairman and CEO until the completion of the merger, whereupon he will serve as Chairman of the combined companies. Dr. Maniscalco will serve the combined companies as its Vice Chairman and Chuck Broes will become the CEO of the combined companies.
