RECENT
EVENTS: DEREGISTRATION
The
Registration Statement on Form S-3 (Registration No. 333-98095) (the
“Registration Statement”) of Pharsight Corporation (“Pharsight”), pertaining to
the registration of certain shares of Pharsight’s common stock, par value $0.001
per share (“Pharsight Common Stock”), to which this Post-Effective Amendment
No. 1 relates, was filed with the Securities and Exchange Commission on
August 14, 2002, as amended on October 11, 2002 and October 30,
2002.
Pharsight,
Tripos (DE), Inc. (“Tripos”) and Pearson Merger Corporation, a wholly-owned
subsidiary of Tripos (“Merger Sub”), entered into an Agreement and Plan of
Merger dated as of September 8, 2008, pursuant to which, among other
things, Merger Sub would be merged with and into Pharsight, Pharsight would
survive as a wholly-owned subsidiary of Tripos and each outstanding share of
Pharsight Common Stock would be converted into the right to receive $5.50 in
cash, without interest (the “Merger”).
On
October 31, 2008, Pharsight effected the Merger pursuant to Section 251 of
the General Corporation Law of the State of Delaware. The Merger
became effective as specified in a Certificate of Merger filed with the
Secretary of State of the State of Delaware on October 31, 2008 (the “Merger
Date”).
As a
result of the Merger, Pharsight has terminated all offerings of Pharsight Common
Stock pursuant to its existing registration statements, including the
Registration Statement. In accordance with an undertaking made by
Pharsight in the Registration Statement to remove from registration, by means of
a post-effective amendment, any shares of Pharsight Common Stock which remain
unsold at the termination of the offering, Pharsight hereby removes from
registration all shares of Pharsight Common Stock registered under the
Registration Statement which remain unsold as of the Merger
Date.
