ITEM 2.  ACQUISITION OF ASSETS.

         On December 28, 2000, United Therapeutics Corporation (the "Company")
announced the acquisition by UTSC Sub Acquisition, Inc., a Delaware corporation
("UTSC Sub") of all the assets and certain liabilities of Medicomp, Inc., a
Florida corporation ("Medicomp"), and Telemedical Procedures, LLC, a Florida
limited liability company ("Telemedical" and, together with Medicomp, the
"Medicomp Companies") pursuant to the terms of an Asset Purchase Agreement dated
as of December 28, 2000. UTSC Sub is a wholly owned subsidiary of Unither
Telemedicine Services Corporation, a Delaware corporation ("UTSC"), which is a
wholly owned subsidiary of the Company. The acquisition closed on December 29,
2000.

         The Company paid $8 million cash and issued approximately 260,000
shares of its common stock in exchange for the assets of the Medicomp
Companies. The stock component of the consideration is subject to adjustment.
Approximately 130,000 of the shares issued to Medicomp are subject to escrow
arrangements pursuant to the terms of an Escrow Agreement dated as of December
28, 2000 among the Company, UTSC Sub, Medicomp, Mahon, Patusky, Rothblatt and
Fisher, Chartered, as escrow agent, and Chicago Title, as successor escrow
agent.

         Medicomp may receive additional shares from the Company on the third
anniversary of the closing if the average closing price of the Company's common
stock over the 30 calendar days prior to the anniversary is less than $70.00 per
share, in order to achieve the equivalence of shares issued to Medicomp at the
closing valued at $70.00 per share (subject to a maximum of 600,000 shares).

         The Medicomp Companies (now UTSC Sub) are related cardiac monitoring
companies based in Florida specializing in providing cardiac Holter and event
monitoring analysis services remotely via proprietary peer-to-peer networks
using telephone dial-up and Internet connections. These services are designed
to address the needs of patients suspected of suffering from cardiac
arrhythmias and other abnormalities such as ischemic events. The companies
also design and manufacture the unique devices required to provide the
services. UTSC will continue this business under the Medicomp name. Ricardo
Balda, President of the Medicomp Companies, has become co-CEO of UTSC, is
serving as CEO of Medicomp, and will join the Board of Directors of the
Company.
