Mr. Schickling will participate in the non-employee director compensation arrangements described in the Company’s 2006 proxy statement. Under the terms of those arrangements, Mr. Schickling will receive, among other things, annual compensation of $12,000, a cash payment of $2,000 for each board meeting attended, and an initial option to purchase 100,000 shares of the Company’s common stock, which vests monthly over a two-year period. In addition, it is expected that Mr. Schickling will execute the Company’s standard form of indemnification agreement.

The Company’s press release announcing Mr. Schickling’s appointment is attached hereto as Exhibit 99.1.

In addition, on June 26, 2007, Philippe Chambon, a member of the board of directors of Pharsight Corporation (the “Company”), notified the Company that he will not stand for re-election to the board of directors at the Company’s 2007 annual meeting of stockholders, scheduled to be held August 8, 2007.
