and authority to enter into this Agreement and to consummate the transactions
contemplated hereby. The execution and delivery of this Agreement and the

by the Company and the Shareholders, and no further action is required on the
part of the Company or the Shareholders to authorize this Agreement and the
transactions contemplated hereby. This Agreement has been duly executed and
delivered by the Company and the Shareholders, and, assuming the due
authorization, execution and delivery by the other parties hereto, constitutes a
valid and binding obligation of the Company and the Shareholders, enforceable
against the Company and the Shareholders in accordance with its terms.

     8.3 Counterparts. This Agreement may be executed in one or more
counterparts, all of which shall be considered one and the same agreement and
shall become effective when one or more counterparts have been signed by each of
the parties and delivered to the other party, it being understood that all
parties need not sign the same counterpart.

     8.4 Entire Agreement; Assignment. This Agreement, the Exhibits hereto, the
Disclosure Schedule, and the documents and instruments and other agreements
among the parties hereto referenced herein: (a) constitute the entire agreement
among the parties with respect to the subject matter hereof and supersede all
prior agreements and understandings both written and oral, among the parties
with respect to the subject matter hereof; (b) are not intended to confer upon
any other person any rights or remedies hereunder; and (c) shall not be assigned
by operation of law or otherwise, except that the Purchaser may assign its

hereunder.

     8.5 Severability. In the event that any provision of this Agreement or the
application thereof, becomes or is declared by a court of competent jurisdiction
to be illegal, void or unenforceable, the remainder of this Agreement will
continue in full force and effect and the application of such provision to other
persons or circumstances will be interpreted so as reasonably to effect the

purposes of such void or unenforceable provision.

     8.6 Other Remedies. Except as otherwise provided herein, any and all
remedies herein expressly conferred upon a party will be deemed cumulative with
and not exclusive of any other remedy conferred hereby, or by law or equity upon
such party, and the exercise by a party of any one remedy will not preclude the
exercise of any other remedy.

     8.7 Governing Law. This Agreement shall be governed by and construed in
accordance with the laws of the State of California, regardless of the laws that
might otherwise govern under applicable principles of conflicts of laws thereof.

     8.8 Rules of Construction. The parties hereto agree that they have been
represented by counsel during the negotiation and execution of this Agreement
and, therefor, waive the application of any law, regulation, holding or rule of
construction providing that ambiguities in an agreement or other document will
be construed against the party drafting such agreement or document.
