reorganization, moratorium and similar laws of general applicability, relating to or affecting creditors rights generally.



5.3 Purchase Entirely for Own Account. The Securities to be received by the Investor hereunder will be acquired for the
Investors own account, not as nominee or agent, and not with a view to the resale or distribution of any part thereof in violation of the 1933 Act, and the Investor has no present intention of selling, granting any participation in, or
otherwise distributing the same in violation of the 1933 Act. The Investor is not a registered broker dealer or an entity engaged in the business of being a broker dealer.



5.4 Investment Experience. The Investor acknowledges that it can bear the economic risk and complete
loss of its investment in the Securities and has such knowledge and experience in financial or business matters that it is capable of evaluating the merits and risks of the investment contemplated hereby.





---

5.5 Disclosure of Information. The Investor has had an opportunity to receive all
additional information related to the Company requested by it and to ask questions of and receive answers from the Company regarding the Company, its business and the terms and conditions of the offering of the Securities. The Investor acknowledges
receipt of copies of the SEC Filings. The Company has provided the Investor with all the information that the Investor has requested in order to decide whether to acquire the Shares and Warrants. Neither such inquiries nor any other due diligence
investigation conducted by the Investor shall modify, amend or affect the Investors right to rely on the Companys representations and warranties contained in this Agreement. The Investor acknowledges that the Company has disclosed to
such Investor that the Company is deferring the release of its third quarter 2003 financial results pending the review of certain transactions from earlier quarters in fiscal year 2003, and that the Company may be required to restate revenues from
the first and second quarters of fiscal year 2003, and possibly earlier periods as well, and that the Investor acknowledges the risks associated with such possible restatements, including but not limited to (i) the risk that the Companys
common stock may be delisted from the Nasdaq SmallCap Market, (ii) the risk that the Company may never regain compliance with the SECs reporting requirements, and (iii) the risk that the Company may be subject to certain penalties, which may
be substantial.



5.6 Restricted
Securities. The Investor understands that the Securities are characterized as restricted securities under the U.S. federal securities laws inasmuch as they are being acquired from the Company in a transaction not involving a public
offering and that under such laws and applicable regulations such securities may be resold without registration under the 1933 Act only in certain limited circumstances.



5.7 Legends. It is understood that, except as provided below, certificates evidencing such Securities
may bear the following or any similar legend:



(a) The securities represented hereby may not be transferred unless (i) such securities have been registered for sale pursuant to the Securities Act of 1933, as amended, (ii) such securities may be sold pursuant to Rule 144(k), or
(iii) the Company has received an opinion of counsel reasonably satisfactory to it that such transfer may lawfully be made without registration under the Securities Act of 1933 or qualification under applicable state securities laws.



(b) If required by the authorities of any
state in connection with the issuance of sale of the Securities, the legend required by such state authority.



Upon the earlier of (i) registration for resale pursuant to the Registration Rights Agreement and receipt by the Company of the
Investors written confirmation that such Securities will not be disposed of except in compliance with the prospectus delivery requirements of the 1933 Act or (ii) Rule 144(k) becoming available the Company shall, upon an Investors
written request, promptly cause certificates evidencing the Securities to be replaced with certificates which do not bear such restrictive legends, and Warrant Shares subsequently issued upon due exercise of the Warrants shall not bear such
restrictive legends provided the provisions of either clause (i) or clause (ii) above, as applicable, are satisfied with respect to such Warrant Shares. When the Company is required to cause unlegended certificates to replace previously issued
legended certificates, if unlegended certificates are not delivered to an Investor within three (3) Business Days of submission by that Investor of legended certificate(s) to the Companys transfer agent together with a representation letter in
customary form, the Company shall be liable to the Investor for liquidated damages (but only if such failure results in the Investor being subject to a buy-in in connection with a trade of the Securities) in an amount equal to 1.5% of the aggregate
purchase price of the Securities evidenced by such certificate(s) for each thirty (30) day period (or portion thereof) beyond such three (3) Business Day that the unlegended certificates have not been so delivered.



5.8 Accredited Investor. The Investor is an
accredited investor as defined in Rule 501(a) of Regulation D, as amended, under the 1933 Act.



5.9 No General Solicitation. The Investor did not learn of the investment in the Securities as a result of any public advertising
or general solicitation.



5.10 Brokers and
Finders. No Person will have, as a result of the transactions contemplated by this Agreement, any valid right, interest or claim against or upon the Company, any Subsidiary or an Investor for any commission, fee or other compensation pursuant to
any agreement, arrangement or understanding entered into by or on behalf of the Investors.

sell and issue the Securities at the Closing is subject to the fulfillment to the satisfaction of the Company on or prior to the Closing Date of the following conditions, any of which may be waived by the Company:



(a) The representations and warranties made by the Investors
in Section 5 hereof, other than the representations and warranties contained in Sections 5.3, 5.4, 5.5, 5.6, 5.7, 5.8 and 5.9 (the Investment Representations), shall be true and correct in all material respects when made, and shall be

(ii) By the Company if any of the conditions set forth in
Section 6.2 shall have become incapable of fulfillment, and shall not have been waived by the Company;



(iii) By the Required Investors if any of the conditions set forth in Section 6.1 shall have become incapable of fulfillment, and shall

by the Company or the Required Investors of their obligations to effect the Closing pursuant to this Section 6.3, written notice thereof shall forthwith be given to the other parties hereto and the obligation of all parties to effect the Closing
shall be terminated, without further action by any party. Nothing in this Section 6.3 shall be deemed to release any party from any liability for any breach by such party of the terms and provisions of this Agreement or the other Transaction
Documents or to impair the right of any party to compel specific performance by any other party of its obligations under this Agreement or the other Transaction Documents.



7. Covenants and Agreements of the Company.



7.1 Reservation of Common Stock. The Company shall at all times reserve and keep available out of its
authorized but unissued shares of Common Stock, solely for the purpose of providing for the exercise of the Warrants, such number of shares of Common Stock as shall from time to time equal the number of shares sufficient to permit the exercise of
the Warrants issued pursuant to this Agreement in accordance with their respective terms.





---

7.2 Reports. So long as the Investors own at least 5% of the Companys
outstanding Common Stock, the Company will furnish to such Investors and/or their assignees such information relating to the Company and its Subsidiaries as from time to time may reasonably be requested by such Investors and/or their assignees;
provided, however, that the Company shall not disclose material nonpublic information to the Investors, or to advisors to or representatives of the Investors, unless prior to disclosure of such information the Company identifies such information as
being material nonpublic information and provides the Investors, such advisors and representatives with the opportunity to accept or refuse to accept such material nonpublic information for review and any Investor wishing to obtain such information
enters into an appropriate confidentiality agreement with the Company with respect thereto.



7.3 No Conflicting Agreements. The Company will not take any action, enter into any agreement or make any commitment that would
conflict or interfere in any material respect with the obligations to the Investors under the Transaction Documents.



7.4 Insurance. The Company shall not materially reduce the insurance coverages described in Section 4.19.



7.5 Compliance with Laws. The Company will comply in
all material respects with all applicable laws, rules, regulations, orders and decrees of all governmental authorities.



7.6 Listing of Underlying Shares and Related Matters. Promptly following the date hereof, the Company shall take all necessary
action to cause the Shares and the Warrant Shares to be listed on the Nasdaq SmallCap Market no later than the Closing Date. Further, if the Company applies to have its Common Stock or other securities traded on any other principal stock exchange or
market, it shall include in such application the Shares and the Warrant Shares and will take such other action as is necessary to cause such Common Stock to be so listed. The Company will use commercially reasonable efforts to continue the listing
and trading of its Common Stock on the Nasdaq SmallCap Market and, in accordance, therewith, will use commercially reasonable efforts to comply in all respects with the Companys reporting, filing and other obligations under the bylaws or rules
of such market or exchange, as applicable.



7.7 Termination of Covenants. The provisions of Sections 7.2 through 7.5 shall terminate and be of no further force and effect upon the earlier of (i) the mutual consent of the Company and the Required Investors or (ii) the date on
which the Companys obligations under the Registration Rights Agreement to register or maintain the effectiveness of any registration covering the Registrable Securities (as such term is defined in the Registration Rights Agreement) shall
terminate.



8. Survival and Indemnification.



8.1 Survival. All representations, warranties,
covenants and agreements contained in this Agreement shall be deemed to be representations, warranties, covenants and agreements as of the date hereof and shall survive the execution and delivery of this Agreement for a period of three (3) years
from the date of this Agreement; provided, however, that the provisions contained in Section 7 hereof shall survive in accordance therewith.



8.2 Indemnification. The Company agrees to indemnify and hold harmless, on an after-tax and after insurance recovery basis, each
Investor and its Affiliates and their respective directors, officers, employees and agents from and against any and all losses, claims, damages, liabilities and expenses (including without limitation reasonable attorney fees and disbursements and
other expenses incurred in connection with investigating, preparing or defending any action, claim or proceeding, pending or threatened and the costs of enforcement hereof) (collectively, Losses) to which such Person may become subject
as a result of any breach of representation, warranty, covenant or agreement made by or to be performed on the part of the Company under the Transaction Documents, and will reimburse any such Person for all such amounts as they are incurred by such
Person.





---

8.3 Conduct of Indemnification Proceedings.Promptly after
receipt by any Person (the Indemnified Person) of notice of any demand, claim or circumstances which would or might give rise to a claim or the commencement of any action, proceeding or investigation in respect of which indemnity
may be sought pursuant to Section 8.2, such Indemnified Person shall promptly notify the Company in writing and the Company shall assume the defense thereof, including the employment of counsel reasonably satisfactory to such Indemnified Person, and
shall assume the payment of all fees and expenses; provided, however, that the failure of any Indemnified Person so to notify the Company shall not relieve the Company of its obligations hereunder except to the extent that the Company
is materially prejudiced by such failure to notify. In any such proceeding, any Indemnified Person shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless:
(i) the Company and the Indemnified Person shall have mutually agreed to the retention of such counsel; or (ii) in the reasonable judgment of counsel to such Indemnified Person representation of both parties by the same counsel would be
inappropriate due to actual or potential differing interests between them. The Company shall not be liable for any settlement of any proceeding effected without its written consent, which consent shall not be unreasonably withheld, but if settled
with such consent, or if there be a final judgment for the plaintiff, the Company shall indemnify and hold harmless such Indemnified Person from and against any loss or liability (to the extent stated above) by reason of such settlement or judgment.
Without the prior written consent of the Indemnified Person, which consent shall not be unreasonably withheld, the Company shall not effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could
have been a party and indemnity could have been sought hereunder by such Indemnified Party, unless such settlement includes an unconditional release of such Indemnified Person from all liability arising out of such proceeding.



9. Miscellaneous.



9.1 Successors and Assigns. This Agreement may not be
assigned by a party hereto without the prior written consent of the Company or the Required Investors, as applicable, provided, however, that an Investor may assign its rights and delegate its duties hereunder in whole or in part to an Affiliate or

inure to the benefit of and be binding upon the respective permitted successors and assigns of the parties. Nothing in this Agreement, express or implied, is intended to confer upon any party other than the parties hereto or their respective

that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof but shall be interpreted as if it were
written so as to be enforceable to the maximum extent permitted by applicable law, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction. To the extent
permitted by applicable law, the parties hereby waive any provision of law which renders any provision hereof prohibited or unenforceable in any respect.
