each share of Foothill California Common Stock, no par value, issued and

At the Effective Time of the Merger, the Surviving Corporation shall assume and

Merger, each outstanding and unexercised option, warrant and right to purchase
or acquire shares of Foothill California Common Stock shall, by virtue of the
Merger and without any action on the part of the holder thereof, be converted
into and become an option, warrant or right to purchase or acquire shares of the
Surviving Corporation's Common Stock on the basis of one share of the Surviving
Corporation's Common Stock for each share of Foothill California Common Stock
issuable pursuant to any such option, warrant or right, and under the same terms
and conditions and at an exercise price per share equal to the exercise price
per share applicable to any such Foothill California option, warrant or right.

         A number of shares of the Surviving Corporation's Common Stock shall be
reserved for issuance upon the exercise of options, warrants and other
securities equal to the number of shares of Foothill California Common Stock so

         3.4 Exchange of Certificates. After the Effective Time of the Merger,
each holder of an outstanding certificate representing shares of Foothill
California Common Stock may, at such shareholder's option, surrender the same
for cancellation to ChaseMellon Shareholder Services, Inc., as transfer agent
(the "Transfer Agent"), and each such holder shall be entitled to receive in
exchange therefor a certificate or certificates representing the number of
shares of the Surviving Corporation's Common Stock into which the surrendered
shares were converted as herein provided. Until so surrendered, each outstanding
certificate theretofore representing shares of Foothill California Common Stock
shall be deemed for all purposes to represent the number of whole shares of the
Surviving Corporation's Common Stock into which the shares of Foothill
California Common Stock were converted in the Merger.

Board of Directors of the Surviving Corporation in compliance with applicable
laws.
