Item 5.  Other Events

     Effective 5:00 p.m. (Eastern Daylight Time) on November 25, 1997, pursuant
to an Agreement and Plan of Merger (the "Merger Agreement") dated as of July 16,
1997, between Ansan Pharmaceuticals, Inc., a Delaware corporation (the
"Company"), and Discovery Laboratories, Inc., a Delaware corporation ("Old
Discovery"), Old Discovery merged with and into the Company (the "Merger"). In
connection with the Merger, the Company changed its name to Discovery
Laboratories, Inc. Concurrently with the effectiveness of the Merger, the
Company effected a 1-for-3 reverse split (the "Reverse Split") of its
outstanding Common Stock, par value $0.001 per share (the "Company Common
Stock"), and its outstanding Class A and Class B Warrants.

     As a consequence of the Merger and the Reverse Split, each share of Common
Stock of Old Discovery will be exchanged for 0.389157 shares of new Company
Common Stock and each share of Series A Convertible Preferred Stock of Old
Discovery (each of which was convertible into 4 shares of the Common Stock of
Old Discovery) will be exchanged for one share of Series B Convertible Preferred
Stock of the Company. Each share of Series B Convertible Preferred Stock of the
Company will be convertible into 1.556628 shares of new Company Common Stock.
Cash will be paid in lieu of fractional shares of new Company Common Stock.

     As a consequence of the Reverse Split, each share of Company Common Stock
outstanding immediately prior to the Merger will be exchanged for 1/3 of a share
of new Company Common Stock. Cash will be paid in lieu of fractional shares of
new Company Common Stock. Each Class A Warrant outstanding immediately prior to
the Merger will be exchanged for 1/3 of a new Class A Warrant and each Class B
Warrant outstanding at such time will be exchanged for 1/3 of a new Class B
Warrant. Each new Class A Warrant will be exercisable for one share of new
Company Common Stock and one new Class B Warrant at an exercise price of $19.50
per new Class A Warrant. Each new Class B Warrant will be exercisable for one
share of new Company Common Stock at an exercise price of $26.25 per Class B
Warrant.

     Continental Stock Transfer & Trust Company ("Continental") has been
retained by the Company to serve as exchange agent in connection with the Merger
and the Reverse Split. As soon as reasonably practicable, the Company will mail
transmittal letters to stockholders of record of Old Discovery at the effective
time of the Merger and will cause Continental to mail transmittal letters to
stockholders and warrantholders of record of the Company at the effective time
of the Merger. The transmittal letters will contain instructions for use in
effecting the surrender of securities for exchange (and for payment in lieu of
fractional shares of new Company Common Stock) pursuant to the Merger and the
Reverse Split.

     As of the effective time of the Merger, Louis R. Bucalo, Lindsay A.
Rosenwald, M.D. and Ilan Cohen resigned from the Board of Directors of the
Company, the size of the Board was increased to ten directors and Steve H.
Kanzer, C.P.A., Esq., James S. Kuo, M.D., Evan Myrianthopoulos, Jeurg F. Geigy,
Esq., Max Link, Ph.D., Herbert H. McDade, Jr., and Marc C. Rogers, M.D., former
