unites SMS with one of the world's largest and most profitable companies serving
the healthcare marketplace. We are excited about the opportunities that this
presents for our employees and customers and the value it provides to our
shareholders. We share a dedication to providing solutions that improve the
quality and efficiency of healthcare. I believe that this merger will enable us
to better meet the demands of today's changing healthcare marketplace."

         SMS specializes in information solutions for hospitals, provides
process and structural consulting, application services, and manages IT
infrastructures.

         Founded in 1969, SMS has over 30 years of network computing experience,
