PHARSIGHT CORPORATION

Employee Stock Purchase Plan Notice (“Notice”)

October 8, 2008

Dear ESPP Participant:

As you may know, Pharsight Corporation (the “ Company ”) has entered into an Agreement and Plan of Merger with Tripos (DE), Inc. (“ Parent ”) and Pearson Merger Corporation, a wholly-owned subsidiary of Parent (“ Merger Sub ”), whereby Merger Sub will merge with and into the Company (the “ Merger ”) and the Company will continue as the surviving corporation and a wholly-owned subsidiary of Parent. The Merger is currently expected to close on or about October 31, 2008 (the “ Effective Time ”).

Please read this Notice carefully, as it explains the effect of the Merger on your current participation in the Pharsight Corporation Amended and Restated 2001 Employee Stock Purchase Plan and 2001 UK Employee Stock Purchase Plan, as amended (either plan, the “ ESPP ”).

The ESPP will be terminated immediately prior to the Effective Time. After such date, you will no longer be able to purchase shares of common stock of the Company through payroll deductions under the ESPP.

You will, however, have one last opportunity to purchase shares of common stock of the Company under the ESPP before it is terminated. In connection with the upcoming Merger, the ESPP administrator will shorten all offering periods currently underway. Consequently, the purchase date of the current offering period will be changed to October 22, 2008, and your accumulated payroll deductions will automatically be applied to purchase shares of common stock of the Company on this new purchase date, unless you withdraw from participation in the ESPP before the new purchase date . Your shortened offering period is considered a fully-effective and completed offering period for all purposes under the ESPP.

If you do not want to purchase shares of common stock of the Company on the new purchase date, you may withdraw from the ESPP by completing a withdrawal notice, available from Quynh Trinh at QTrinh@pharsight.com and submitting it to her at QTrinh@pharsight.com or calling her at (650) 314-3810. Your completed withdrawal notice must be received before October 22, 2008, or your accumulated payroll deductions automatically will be applied to purchase shares of common stock of the Company under the ESPP.

If you do not withdraw from the ESPP as described in this Notice, each shares of common stock of the Company purchased on October 22, 2008, automatically will be converted into a right to receive the Merger consideration per share of common stock, which is $5.50 per share, at the Effective Time.

If you have any questions regarding the foregoing, please contact Quynh at (650) 314-3832.
