Item 5. Other Events.

         On September 23, 2002, United Therapeutics Corporation (the “Company”) issued a press release announcing that all four Durable Medical Equipment Regional Carriers (DMERCs), which together make determinations to provide Medicare coverage for durable medical equipment and related drugs and supplies throughout the United States, have announced that they will provide reimbursement of Remodulin therapy retroactive to May 21, 2002. A copy of the press release is attached hereto and incorporated herein by this reference.

         On September 20, 2002, the Company closed on the purchase of a commercial property adjacent to its headquarters offices in Silver Spring, Maryland. The purchase price was approximately $1.7 million and was paid in cash. On September 24, 2002, the Company agreed on principal terms for the purchase of an additional contiguous commercial property for approximately $1.3 million in exchange for cash and a note payable, with settlement expected to occur in January 2003. Subject to zoning and other necessary governmental approvals, the Company plans to use these properties for the development, formulation and testing of the Company’s anti-cancer immunotherapeutic monoclonal antibody platform and for future expansion. The Company currently anticipates spending approximately $10 to $20 million over the next two to three years to redevelop these facilities. Pending commencement of such redevelopment of the properties, the Company anticipates leasing the properties to the existing commercial tenants.
