	 	2.	 	BUYERS’ REPRESENTATIONS AND WARRANTIES.





Each Buyer represents and warrants, severally and not jointly, that:



2.1. Information. Buyer and its advisors, if any, have been furnished with all
materials relating to the business, finances and operations of the Company and materials relating
to the offer and sale of the Shares that have been requested by Buyer. Buyer and its advisors, if
any, have been afforded the opportunity to ask questions of the Company. Buyer understands that
its investment in the Shares involves a high degree of risk. Neither such inquiries nor any other
investigation conducted by or on behalf of Buyer or its advisors shall modify, amend or affect
Buyer’s right to rely on the truth, accuracy and completeness of the disclosure made to Buyer or
its advisors in respect of the Company or this transaction and the Company’s representations and
warranties contained in this Agreement.



2.2. No Governmental Review. Buyer understands that no United States federal or state

such authorities passed upon or endorsed the merits of the offering of the Shares.

involving the Company’s securities during the period beginning 30 days prior to the date of this

any shares of common stock currently held by Buyer shall be deemed to be held as “long” by Buyer.



2.4. Validity; Enforcement. Buyer has the requisite right, power, authority and
capacity to enter into this Agreement and to consummate the transactions contemplated hereby. This
Agreement has been duly and validly authorized, executed and delivered on behalf of Buyer and,

specified in its address on the Schedule of Buyers.



2.6. Legal, Tax or Investment Advice. Buyer understands that nothing in this
Agreement or any other materials presented to Buyer in connection with the purchase and sale of the
Shares constitutes legal, tax or investment advice. Buyer has consulted such legal, tax and
investment advisors as it, in its sole discretion, has deemed necessary or appropriate in
connection with its purchase of Securities.



2.7. Broker — Dealer. Buyer is not a registered broker dealer.




	 	3.	 	REPRESENTATIONS AND WARRANTIES OF THE COMPANY.





The Company represents and warrants to each of the Buyers that:



3.1. Good Standing; Qualification. The Company is duly organized and validly existing
in good standing under the laws of the State of California. Each of the Company and its
subsidiaries (as defined in Rule 405 under the Securities Act of 1933 (the “Securities Act”)) has
full power and authority to own, operate and occupy its properties and to conduct its business as
presently conducted and as described in the documents filed by the Company under the Securities
Exchange Act of 1934 (the “Exchange Act”), since September 30, 2005 through the date hereof,
including, without limitation, its most recent Annual Report on Form 10-K filed with the U.S.
Securities and Exchange Commission (the “Exchange Act Documents”) and is registered or qualified to
do business and in good standing in each jurisdiction in which the nature of the business conducted
by it or the location of the properties owned or leased by it requires such qualification and where
the failure to be so qualified would have a material adverse effect upon the condition (financial
or otherwise), earnings, or business (such business being as described in the Exchange Act
Documents), properties or operations of the Company and its subsidiaries, considered as one
enterprise, or impair the Company’s ability to perform on a timely basis its obligations under this
Agreement (any of the foregoing, a “Material Adverse Effect”), and no proceeding has been
instituted in any such jurisdiction, revoking, limiting or curtailing, or seeking to revoke, limit
or curtail, such power and authority or qualification.



3.2. Due Authorization and Valid Issuance. The Company has all requisite power and
authority to execute, deliver and perform its obligations hereunder, and this Agreement has been
duly authorized and validly executed and delivered by the Company and, assuming due execution and
delivery hereof by the Buyers, shall constitute a legal, valid and binding agreement of the Company
enforceable against the Company in accordance with their terms, except as rights to indemnity and
contribution may be limited by state or federal securities laws or the public policy underlying
such laws, except as enforceability may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium or similar laws affecting creditors’ and contracting parties’ rights
generally and except as enforceability may be subject to general principles of equity (regardless
of whether such enforceability is considered in a proceeding in equity or at law). The Shares
being purchased by the Buyer hereunder will, upon issuance and payment therefor pursuant to the
terms hereof, be duly authorized, validly issued, fully-paid and nonassessable.



3.3. Non-Contravention. The execution and delivery of this Agreement, the sale of
the Shares, the fulfillment of the terms of this Agreement and the consummation of the transactions
contemplated hereby will not (A) conflict with or constitute a violation of, or default (with the
passage of time or otherwise) under, (i) any contract, agreement or other instrument filed or
incorporated by reference as an exhibit to any of the Exchange Act Documents (any such contract,
agreement or instrument, an “Exchange Act Exhibit”), (ii) the charter, by-laws or other
organizational documents of the Company or any subsidiary, or (iii) assuming the correctness of the
representations and warranties of the Buyers set forth herein, any law, administrative regulation,
ordinance or order of any court or governmental agency, arbitration panel or authority applicable
to the Company or any subsidiary or their respective properties, except in the case of clauses (i)
and (iii) for any such conflicts, violations or defaults which do not have or would be reasonably
likely to result in a Material Adverse Effect or (B) result in the creation or imposition of any
lien, encumbrance, claim, security interest or restriction whatsoever upon any of the material
properties or assets of the Company or any subsidiary or an acceleration of indebtedness pursuant
to any obligation, agreement or condition contained in any Exchange Act Exhibit. Assuming the
correctness of the representations and warranties of the Buyers set forth herein, no consent,
approval, authorization or other order of, or registration, qualification or filing with, any
regulatory body, administrative agency, or other governmental body in the United States or any
other person is required for the execution and delivery of this Agreement and the valid issuance

September 30, 2005, increased as set forth in the next sentence. Other than in the ordinary course
of business, the Company has not issued any capital stock since the Reference Date other than

arrangement of any kind to which the Company is a party and relating to the issuance or sale of any

shareholder, the Board of Directors of the Company or others is required for the issuance and sale
of the Shares. The Company owns the entire equity interest in each of its subsidiaries, free and
clear of any pledge, lien, security interest, encumbrance, claim or equitable interest, other than

charter, bylaws, or other organizational document, or in violation of any law, administrative
regulation, ordinance or order of any court or governmental agency, arbitration panel or authority

would be reasonably likely to have a Material Adverse Effect, or is in default (and there exists no

respect in the performance of Exchange Act Exhibit, which would have or reasonably likely to result
in a Material Adverse Effect.



3.7. Governmental Permits, Etc. Each of the Company and its subsidiaries has all
necessary franchises, licenses, certificates and other authorizations from any foreign, federal,

Documents, (i) each of the Company and its subsidiaries owns or possesses sufficient rights to use

described in the Exchange Act Documents, except where the failure to currently own or possess would
not have or reasonably be expected to result in a Material Adverse Effect, (ii) to the knowledge of
the Company, neither the Company nor any of its subsidiaries is infringing any rights of a third
party with respect to any Intellectual Property, (iii) neither the Company nor any of its
subsidiaries has received any notice of, or has any knowledge of, any asserted infringement by the
Company or any of its subsidiaries of, any rights of a third party with respect to any Intellectual

a Material Adverse Effect if determined adversely to the Company and (iv) neither the Company nor
any of its subsidiaries has received any notice of, or has any knowledge of, infringement by a
third party with respect to any Intellectual Property rights of the Company or of any subsidiary
that, individually or in the aggregate, would have or reasonably be expected to result in a
Material Adverse Effect.

notes contained in the Exchange Act Documents present fairly, in accordance with generally accepted
accounting principles, the financial position of the Company and its subsidiaries as of the dates
indicated, and the results of its operations and cash flows for the periods therein specified

of, nor may any provision hereof be enforced by, any other person.



7.9. Publicity. The Company and each Buyer shall have the right to approve before
issuance any press releases or any other public statements with respect to the transactions
contemplated hereby; provided, however, that the Company shall be entitled, without
the prior approval of any Buyer, to make any press release or other public disclosure with respect
to such transactions as is required by applicable law and regulations.



7.10. Further Assurances. Each party shall do and perform, or cause to be done and
performed, all such further acts and things, and shall execute and deliver all such other
agreements, certificates, instruments and documents, as the other party may reasonably request in
order to carry out the intent and accomplish the purposes of this Agreement and the consummation of
the transactions contemplated hereby.



7.11. Termination. In the event that the Closing shall not have occurred with respect
to a Buyer within ten business days from the date of this Agreement due to the Company’s or such
Buyer’s failure to satisfy the conditions set forth in Sections 6 and 7 above (and the
non-breaching party’s failure to waive such unsatisfied condition(s)), the non-breaching party
shall have the option to terminate this Agreement with respect to such breaching party at the close
of business on such date without liability of any party to any other party.



7.12. Remedies. Each Buyer and each holder of the Shares shall have all rights and
remedies set forth in this Agreement and all of the rights that such holders have under any law.
Any person having any rights under any provision of this Agreement shall be entitled to enforce
such rights specifically (without posting a bond or other security), to recover damages by reason
of any breach of any provision of this Agreement and to exercise all other rights granted by law.



7.13. Obligations of Buyers Several and Not Joint. The obligations of each Buyer
hereunder are several and not joint with the obligations of any other Buyer, and no Buyer shall be
responsible in any way for the performance of the obligations of any other Buyer under any
Agreement. Nothing contained herein, and no action taken by any Buyer hereto, shall be deemed to
constitute the Buyers as a partnership, an association, a joint venture or any other kind of
entity, or create a presumption that the Buyers are in any way acting in concert or as a group with
respect to such obligations or the transactions contemplated hereby, provided that such obligations
or the transactions contemplated hereby may be modified, amended or waived in accordance with
Section 7.5 of this Agreement. Each Buyer shall be entitled to independently protect and enforce
its rights, including without limitation the rights arising out of this Agreement (provided, that
such rights may be modified, amended or waived in accordance with Section 7.5), and it shall not be
necessary for any other Buyer to be joined as an additional party in any proceeding for such
purpose.
