Item 8.01.  Other Events.

On August 30, 2007, Paul Mahon, Executive Vice President, Strategic Planning and General Counsel of United Therapeutics Corporation, adopted a prearranged trading plan in accordance with Securities and Exchange Commission Rule 10b5-1 and United Therapeutics’ Securities Trades by Company Personnel Policy.

Rule 10b5-1 of the Securities Exchange Act of 1934 permits officers and directors of public companies to adopt predetermined written plans for trading specified amounts of company stock when they are not in possession of material nonpublic information in order to gradually diversify their investment portfolios, to minimize the market effect of stock sales by spreading them out over an extended period of time, and to avoid concerns about initiating stock transactions while in possession of material nonpublic information.

The 10b5-1 plan adopted by Mr. Mahon involves a market order to sell 5,000 shares of United Therapeutics common stock on each of the first three Wednesdays in November 2007, with all such shares acquired through the exercise of employee stock options.  Shares will be sold under the plan on the open market at prevailing market prices subject to a minimum price threshold.

The plan will expire when the maximum amount of 15,000 shares has been sold or December 31, 2008, whichever first occurs.

The transactions under this plan will be disclosed publicly through Form 144 filings with the Securities and Exchange Commission.  Corresponding Form 4 filings will also be posted on United Therapeutics’ website.
