Each of the Company and each Subsidiary is an entity duly incorporated or otherwise organized, validly existing and in good standing under the laws of the jurisdiction of its incorporation or organization (as applicable), with the requisite power and authority to own and use its properties and assets and to carry on its business as currently conducted. Neither the Company nor any Subsidiary is in violation of any of the provisions of its respective certificate or articles of incorporation, bylaws or other organizational or charter documents. Each of the Company and each Subsidiary is duly qualified to conduct business and is in good standing as a foreign corporation or other entity in each jurisdiction in which the nature of the business conducted or property owned by it makes such qualification necessary or appropriate, except where the failure to be so qualified or in good standing, as the case may be, could not, individually or in the aggregate, have or reasonably be expected to result in (i) an adverse effect on the legality, validity or enforceability of any Transaction Document, (ii) a material and adverse effect on the results of operations, assets, prospects, business or condition (financial or otherwise) of the Company and the Subsidiaries, taken as a whole, or (iii) an adverse impairment to the Company’s ability to perform on a timely basis its obligations under any Transaction Document (any of (i), (ii) or (iii), a “Material Adverse Effect”).

(c)           Authorization; Enforcement. The Company has the requisite corporate power and authority to enter into and to consummate the transactions contemplated by each of the Transaction Documents and otherwise to carry out its obligations thereunder.  The execution and delivery of each of the Transaction Documents by the Company and the consummation by it of the transactions contemplated thereby have been duly authorized by all necessary corporate

action on the part of the Company and no further corporate action is required by the Company or its stockholders in connection therewith.  Each Transaction Document has been (or upon delivery will have been) duly executed by the Company and, when delivered in accordance with the terms hereof, will constitute the valid and binding obligation of the Company enforceable against the Company in accordance with its 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).

(d)           No Conflicts. The execution and delivery of the Transaction Documents by the Company and the consummation and performance by the Company of the transactions contemplated thereby do not and will not (i) conflict with or violate any provision of the Company’s or any Subsidiary’s certificate or articles of incorporation, bylaws or other organizational or charter documents, (ii) conflict with, or constitute a default (or an event that with notice or lapse of time or both would become a default) under, or give to others any rights of termination, amendment, acceleration or cancellation (with or without notice, lapse of time or both) of, any agreement, credit facility, debt or other instrument (evidencing a Company or Subsidiary debt or otherwise) or other understanding to which the Company or any Subsidiary is a party or by which any property or asset of the Company or any Subsidiary is bound or affected, or (iii) result in a violation of any law, rule, regulation, order, judgment, injunction, decree or other restriction of any court or governmental authority to which the Company or a Subsidiary is subject (including federal and state securities laws and regulations), or by which any property or asset of the Company or a Subsidiary is bound or affected; except in the case of each of clauses (ii) and (iii), such as could not, individually or in the aggregate, have or reasonably be expected to result in a Material Adverse Effect.

(e)           Filings, Consents and Approvals.

(h)           SEC Reports; Financial Statements. The Company has filed all reports required to be filed by it under the Securities Act and the Exchange Act, including pursuant to Section 13(a) or 15(d) thereof, for the twelve months preceding the date hereof (or such shorter period as the Company was required by law to file such reports) (the foregoing materials including all exhibits and schedules thereto, being collectively referred to herein as the “SEC Reports” and, together with the Schedules to this Agreement, the “Disclosure Materials”) on a timely basis or has timely filed a valid extension of such time of filing and has filed any such SEC Reports prior to the expiration of any such extension.  As of their respective dates, the SEC Reports complied in all material respects with the requirements of the Securities Act and the Exchange Act and the rules and regulations of the Commission promulgated thereunder, and none of the SEC Reports, when filed, contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading.  The financial statements of the Company included in the SEC Reports comply in all material respects with applicable accounting requirements and the rules and regulations of the Commission with respect thereto as in effect at the time of filing.  Such financial statements have been prepared in accordance with U.S. generally accepted accounting principles applied on a consistent basis during the periods involved (“GAAP”), except as may be otherwise specified in such financial statements or the notes thereto, and fairly present in all material respects the financial position of the Company and its consolidated Subsidiaries as of and for the dates thereof and the results of operations and cash flows for the periods then ended, subject, in the

individually or in the aggregate, have or reasonably be expected to result in a Material Adverse Effect.  The Company is in compliance with the applicable requirements of the Sarbanes-Oxley Act of 2002 and the rules and regulations thereunder promulgated by the Commission, except where such noncompliance could not have or reasonably be expected to result in a Material Adverse Effect.

(m)          Regulatory Permits. The Company and the Subsidiaries possess all certificates, authorizations and permits issued by the appropriate federal, state, local or foreign regulatory authorities necessary to conduct their respective businesses as described in the SEC Reports, except where the failure to possess such permits would not, individually or in the aggregate, have or reasonably be expected to result in a Material Adverse Effect (“Material Permits”), and neither the Company nor any Subsidiary has received any notice of proceedings relating to the revocation or modification of any Material Permit.

(n)           Title to Assets.

No Intellectual Property has been or is now involved in any cancellation, dispute or litigation, and, to the Company’s knowledge, no such action is threatened. No patent of the Company or any Subsidiary has been or is now involved in any interference, reissue, re-examination or opposition proceeding.

(ii)           All of the licenses and sublicenses and consent, royalty or other agreements concerning Intellectual Property to which the Company or any Subsidiary is a party or by which any of their assets are bound (other than generally commercially available, non-custom, off-the-shelf software application programs having a retail acquisition price of less than $10,000 per license) (collectively, “License Agreements”) are valid and binding obligations of the Company or its Subsidiaries that are parties thereto and, to the Company’s knowledge, the other parties thereto, enforceable in accordance with their terms, except to the extent that enforcement thereof may be limited by bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance or other similar laws affecting the enforcement of creditors’ rights generally, and, to the Company’s knowledge, there exists no event or condition which will

(iv)          To the Company’s knowledge, the conduct of the Company’s or Subsidiary’s business as currently conducted does not infringe or otherwise impair or conflict with (collectively, “Infringe”) any Intellectual Property rights of any third party, or violate any confidentiality obligation owed by the Company to a third party. To the Company’s knowledge, the Intellectual Property is not being Infringed by any third party. There is no litigation or order pending or outstanding or, to the Company’s knowledge, threatened, that seeks to limit or challenge or that concerns the ownership, use, validity or enforceability of any Intellectual Property or Confidential Information, and, to the Company’s knowledge, there is no valid basis for the same.

(v)           The consummation of the transactions contemplated by the Transaction Documents will not result in the alteration, loss, impairment of or restriction on the Company’s or any Subsidiary’s ownership or right to use any of the Intellectual Property.

(vi)          The Company and each Subsidiary has taken reasonable steps to protect the Company’s or Subsidiary’s rights in their Intellectual Property and Confidential Information. Except under confidentiality obligations, there has been no material disclosure of any Confidential Information to any third party.

(p)           Insurance. The Company and the Subsidiaries are insured by insurers of recognized financial responsibility against such losses and risks and in such amounts as are prudent and customary in the businesses in which the Company and the Subsidiaries are engaged.  The Company believes that it will be able to renew its existing insurance coverage as and when such coverage expires or to obtain similar coverage from similar insurers as may be necessary to continue its business without a material increase in cost.

(q)           Transactions With Affiliates and Employees. Except as set forth in the SEC Reports, none of the officers or directors of the Company and, to the knowledge of the Company, none of the employees of the Company is presently a party to any transaction with the Company or any Subsidiary (other than for services as employees, officers and directors), including any contract, agreement or other arrangement providing for the furnishing of services to or by, providing for rental of real or personal property to or from, or otherwise requiring payments to or from any officer, director or such employee or, to the knowledge of the Company, any entity in which any officer, director, or any such employee has a substantial interest or is an officer, director, trustee or partner.

(r)            Internal Accounting Controls. The Company is in material compliance with all provisions of the Sarbanes-Oxley Act that are applicable to the Company as of the

10

Closing. The Company maintains a system of internal accounting controls sufficient to provide reasonable assurance that (i) transactions are executed in accordance with management’s general or specific authorizations, (ii) transactions are recorded as necessary to permit preparation of financial statements in conformity with generally accepted accounting principles and to maintain asset accountability, (iii) access to assets is permitted only in accordance with management’s general or specific authorization, and (iv) the recorded accountability for assets is compared with the existing assets at reasonable intervals and appropriate action is taken with respect to any differences. The Company has established disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) for the Company and designed such disclosure controls and procedures to ensure that material information relating to the Company, including its Subsidiaries, required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the certifying officers by others within those entities, particularly during the period in which the Company’s most recently filed periodic report under the Exchange Act, as the case may be, is being prepared. The Company’s certifying officers have evaluated the effectiveness of the Company’s controls and procedures as of the end of the period covered by the most recently filed periodic report under the Exchange Act (such date, the “Evaluation Date”). The Company presented in its most recently filed periodic report under the Exchange Act the conclusions of the certifying officers about the effectiveness of the disclosure controls and procedures based on their evaluations as of the Evaluation Date. Since the Evaluation Date, there has not been any material reduction in the Company’s internal controls over financial reporting . Ernst & Young LLP, which expressed its opinion with respect to the consolidated financial statements to be incorporated by reference to the Company’s Annual Report on Form 10-K for the year ended June 30, 2005 into the Registration Statement, have advised the Company that they are, and to the knowledge of the Company they are, independent accountants as required by the Securities Act and the rules and regulations promulgated thereunder.

(s)           Solvency. Based on the financial condition of the Company as of the Closing (and assuming that the Closing shall have occurred): (i) the Company’s fair saleable value of its assets exceeds the amount that will be required to be paid on or in respect of the Company’s existing debts and other liabilities (including known contingent liabilities) as they mature; (ii) the Company’s assets do not constitute unreasonably small capital to carry on its business for the current fiscal year as now conducted and as proposed to be conducted including its capital needs taking into account the particular capital requirements of the business conducted by the Company, and projected capital requirements and capital availability thereof; and (iii) the current cash flow of the Company, together with the proceeds the Company would receive, were it to liquidate all of its assets, after taking into account all anticipated uses of the cash, would be sufficient to pay all amounts on or in respect of its debt when such amounts are required to be paid.  The Company does not intend to incur debts beyond its ability to pay such debts as they mature (taking into account the timing and amounts of cash to be payable on or in respect of its debt).

(t)            Certain Fees. Except for dealings with the Placement Agents (defined below), no brokerage or finder’s fees or commissions are or will be payable by the Company to any broker, financial advisor or consultant, finder, placement agent, investment banker, bank or other Person with respect to the transactions contemplated by the Transaction Documents. The

11

Purchasers shall have no obligation with respect to any fees or with respect to any claims (other than such fees or commissions owed by a Purchaser pursuant to written agreements executed by such Purchaser which fees or commissions shall be the sole responsibility of such Purchaser) made by or on behalf of other Persons for fees of a type contemplated in this Section that may be due in connection with the transactions contemplated by the Transaction Documents.

(u)           Certain Registration Matters. Assuming the accuracy of the Purchasers’ representations and warranties set forth in Section 3.2(b) to (e), no registration under the Securities Act is required for the offer and sale of the Securities by the Company to the Purchasers under the Transaction Documents.  The Company is eligible to register the resale of its Common Stock for resale by the Purchasers under Form S-3 promulgated under the Securities Act.  Except as set forth in Schedule 3.1(u), the Company has not granted or agreed to grant to any Person any rights (including “piggy-back” registration rights) to have any securities of the Company registered with the Commission or any other governmental authority that have not been satisfied.

(v)           Listing and Maintenance Requirements. Except as specified in the SEC Reports, the Company has not, in the two years preceding the date hereof, received notice from any Trading Market on which the Common Stock is or has been listed or quoted for trading to the effect that the Company is not in compliance with the listing or maintenance requirements thereof.  Except as specified in the SEC Reports, the Company is, and has no reason to believe that it will not in the foreseeable future continue to be, in compliance with the listing and maintenance requirements for continued listing of the Common Stock on the NASDAQ Capital Market. The issuance and sale of the Securities under the Transaction Documents does not contravene the rules and regulations of the Trading Market on which the Common Stock is currently listed or quoted, and no approval of the stockholders of the Company thereunder is required for the Company to issue and deliver to the Purchasers the maximum number of Securities contemplated by Transaction Documents, including such as may be required pursuant to the Nasdaq Stock Market, Inc. Marketplace Rules and NASDAQ Staff Interpretative Letters thereunder concerning stockholder approval requirements with regard to discounted private placements equal to 20% or more of the common stock or 20% or more of the voting power outstanding before such issuance.

(w)          Investment Company. The Company is not, and is not an Affiliate of, an “investment company” within the meaning of the Investment Company Act of 1940, as amended (the “Investment Company Act”). After giving effect to the transactions contemplated by this Agreement, the Company will not be, and will not be an Affiliate of, an “investment company” within the meaning of the Investment Company Act.

(x)            Application of Takeover Protections. The Company has taken all necessary action, if any, in order to render inapplicable any control share acquisition, business combination, poison pill (including any distribution under a rights agreement) or other similar anti-takeover provision under the Company’s certificate of incorporation (or similar charter documents), the Company’s by-laws (as amended and in effect) or the laws of its state of incorporation that is or could reasonably be expected to become applicable to the Purchasers as a result of the Purchasers and the Company fulfilling their obligations or exercising their rights

12

under the Transaction Documents, including without limitation the Company’s issuance of the Securities and the Purchasers’ ownership of the Securities.

(y)           No Additional Agreements. The Company does not have any agreement or understanding with any Purchaser with respect to the transactions contemplated by the Transaction Documents other than as specified in the Transaction Documents.

(z)            Foreign Corrupt Practices.

The Company further represents to each Purchaser that the Company’s decision to enter into the Transaction Documents has been based solely on the independent evaluation by the Company and its representatives of the Transaction Documents and the transactions contemplated thereby.

(bb)         Disclosure; Price Manipulation.

13

the transactions contemplated hereby, furnished by or on behalf of the Company (including the Company’s representations and warranties set forth in this Agreement) are true and correct in all material respects and do not contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements made therein, in light of the circumstances under which they were made, not misleading. The Company has not taken and will not take any action designed to or that might reasonably be expected to cause or result in an unlawful manipulation of the price of the Common Stock to facilitate the sale or resale of the Securities.

No Securities were offered or sold to such Purchaser by means of any form of general solicitation or general advertising, and in connection therewith such Purchaser did not: (A) receive or review any advertisement, article, notice or other communication published in a newspaper or magazine or similar media or broadcast over television or radio, whether closed circuit or generally available; or (B) attend any seminar meeting or industry investor conference whose attendees were invited by any general solicitation or general advertising.

(g)           Reliance.

ARTICLE IV.

OTHER AGREEMENTS OF THE PARTIES

4.1           (a)           The Securities may only be disposed of pursuant to an effective registration statement under the Securities Act, to the Company or pursuant to an available exemption from, or in a transaction not subject to, the registration requirements of the Securities Act, and in compliance with any applicable state securities laws.  In connection with any transfer of the Securities other than pursuant to an effective registration statement, to the Company, to an Affiliate of a Purchaser or in connection with a pledge as contemplated in Section 4.1(b), the Company may require the transferor thereof to provide to the Company an opinion of counsel selected by the transferor, the form and substance of which opinion shall be reasonably satisfactory to the Company, to the effect that such transfer does not require registration of such transferred Securities under the Securities Act.

(b)           Certificates evidencing the Securities will contain the following legend, so long as is required by this Section 4.1(b) or Section 4.1(c):

[NEITHER THESE SECURITIES NOR THE SECURITIES ISSUABLE UPON EXERCISE OF THESE SECURITIES HAVE BEEN REGISTERED][THESE SECURITIES HAVE NOT BEEN REGISTERED] WITH THE SECURITIES AND EXCHANGE COMMISSION OR THE SECURITIES COMMISSION OF ANY STATE IN RELIANCE UPON AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT

16

PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR PURSUANT TO AN AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS AS EVIDENCED BY A LEGAL OPINION OF COUNSEL TO THE TRANSFEROR TO SUCH EFFECT, THE SUBSTANCE OF WHICH SHALL BE REASONABLY ACCEPTABLE TO THE COMPANY.  [THESE SECURITIES AND THE SECURITIES ISSUABLE UPON EXERCISE OF THESE SECURITIES][THESE SECURITIES] MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT SECURED BY SUCH SECURITIES.

The Company acknowledges and agrees that a Purchaser may from time to time pledge and/or grant a security interest in some or all of the Securities, in accordance with applicable securities laws, pursuant to a bona fide margin agreement in connection with a bona fide margin account and, if required under the terms of such agreement or account, such Purchaser may transfer pledged or secured Securities to the pledgees or secured parties.  Such a pledge or transfer would not be subject to approval or consent of the Company and no legal opinion of legal counsel to the pledgee, secured party or pledgor shall be required in connection with the pledge, but such legal opinion may be required in connection with a subsequent transfer following default by the Purchaser transferee of the pledge.  No notice shall be required of such pledge.  At the appropriate Purchaser’s expense, the Company will execute and deliver such reasonable documentation as a pledgee or secured party of Securities may reasonably request in connection with a pledge or transfer of the Securities including the preparation and filing of any required prospectus supplement under Rule 424(b)(3) of the Securities Act or other applicable provision of the Securities Act to appropriately amend the list of Selling Stockholders thereunder.

(c)           Certificates evidencing the Shares and Warrant Shares shall not contain any legend (including the legend set forth in Section 4.1(b)): (i) following any sale of such Shares or Warrant Shares pursuant to a registration statement (including the Registration Statement) covering the resale of such Shares and Warrant Shares that is effective under the Securities Act, or (ii) following any sale of such Shares or Warrant Shares pursuant to Rule 144, or (iii) while such Shares or Warrant Shares are eligible for sale under Rule 144(k), or (iv) if such legend is not required under applicable requirements of the Securities Act (including judicial interpretations and pronouncements issued by the Staff of the Commission).  The Company shall cause its counsel to issue any legal opinion or instruction required by the Company’s transfer agent to comply with the requirements set forth in this Section. If all or any portion of a Warrant is exercised at any time when there is an effective registration statement to cover the resale of the Warrant Shares, such Warrant Shares shall be issued free of all legends. Following the occurrence of (i), (ii) or (iii) or at such earlier time as a legend is no longer required for the Shares and Warrant Shares under this Section 4.1(c), the Company will, no later than three (3) Trading Days following the delivery by a Purchaser to the Company or the Company’s transfer agent of a certificate representing Shares or Warrant Shares containing a restrictive legend (such third Trading Day, the “Legend Removal Date”), deliver or cause to be delivered to such Purchaser or its transferee a certificate representing such Shares or Warrant

17

Shares that is free from all restrictive and other legends.  The Company may not make any notation on its records or give instructions to any transfer agent of the Company that enlarge the restrictions on transfer set forth in this Section except as it may reasonably determine are necessary or appropriate to comply or to ensure compliance with those applicable laws that are enacted or modified after the Closing.

(d)           In addition to such Purchaser’s other available remedies, the Company shall pay to a Purchaser, in cash, as partial liquidated damages and not as a penalty, for each $1,000 of Shares or Warrant Shares (based on the Closing Price of the Common Stock on the date such Securities are submitted to the Company’s transfer agent) delivered for removal of the restrictive legend and subject to Section 4.1(c), $10 per Trading Day for each Trading Day commencing two (2) Business Days after the Legend Removal Date (increasing to $20 per Trading Day after the first five (5) Trading Days for which such damages have begun to accrue) for each Trading Day after the two (2) Business Days following the Legend Removal Date until such certificate is delivered without a legend (“Liquidated Damages”); provided, however, with respect to the Warrant Shares only, in the event the Liquidated Damages clause in this section 4.1(d) will cause the warrants issued by the Company in this transaction to be a liability on the Company’s balance sheet pursuant to Rule EITF 00-19 as interpreted by the Financial Accounting Standards Board or the accounting staff of the SEC, then and only then, the Liquidated Damages applicable to Warrant Shares delivered by any investor for removal of the restrictive legend shall be capped at $120 for each $1,000 of Warrant Shares delivered. Nothing herein shall limit such Purchaser’s right to pursue actual damages for the Company’s failure to deliver certificates representing any Securities as required by the Transaction Documents, and such Purchaser shall have the right to pursue all remedies available to it at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief.

4.2           Furnishing of Information. As long as any Purchaser owns the Securities, the Company covenants to timely file (or obtain extensions in respect thereof and file within the applicable grace period) all reports required to be filed by the Company after the date hereof pursuant to the Exchange Act.  As long as any Purchaser owns the Securities, if the Company is not required to file reports pursuant to such laws, it will prepare and furnish to the Purchasers and make publicly available in accordance with Rule 144(c) such information as is required for the Purchasers to sell the Shares and Warrant Shares under Rule 144. The Company further covenants that it will take such further action as any holder of Securities may reasonably request, all to the extent required from time to time to enable such Person to sell such Shares and Warrant Shares without registration under the Securities Act within the limitation of the exemptions provided by Rule 144.

4.3           Integration. The Company shall not, and shall use its best efforts to ensure that no Affiliate of the Company shall, sell, offer for sale or solicit offers to buy or otherwise negotiate in respect of any security (as defined in Section 2 of the Securities Act) that will be integrated with the offer or sale of the Securities in a manner that would require the registration under the Securities Act of the sale of the Securities to the Purchasers, or that will be integrated with the offer or sale of the Securities for purposes of the rules and regulations of any Trading Market.

18

4.4           Securities Laws Disclosure; Publicity. By no later than 9:15 a.m. (New York time) on the date of execution of this Agreement or 9:15 a.m. (New York time) on the Trading Day following the execution of this Agreement, the Company shall issue a press release disclosing the consummation of the transactions contemplated hereby and file a Current Report on Form 8-K disclosing the consummation and material terms of the transactions contemplated hereby.  In addition, the Company will make such other filings and notices in the manner and time required by the Commission and the Trading Market on which the Common Stock is listed.  Notwithstanding the foregoing, the Company shall not publicly disclose the name of any Purchaser, or include the name of any Purchaser in any filing with the Commission (other than the Registration Statement and any exhibits to filings made in respect of this transaction in accordance with periodic filing requirements under the Exchange Act) or any regulatory agency or Trading Market, without the prior written consent of such Purchaser, except to the extent such disclosure is required by law or Trading Market regulations, in which case the Company shall provide the Purchasers with prior notice of such disclosure.

4.5           Non-Public Information. The Company covenants and agrees that neither it nor any other Person acting on its behalf will provide any Purchaser or its agents or counsel with any information that the Company believes constitutes material non-public information, unless prior thereto such Purchaser shall have executed a written agreement regarding the confidentiality and use of such information.  The Company understands and confirms that each Purchaser shall be relying on the foregoing representations in effecting transactions in securities of the Company.

4.6           Indemnification of Purchasers. In addition to the indemnity provided in the Registration Rights Agreement, the Company will (i) indemnify and hold each Purchaser and its directors, officers, stockholders, partners, employees and agents (each, a “Purchaser Party”) harmless from any and all losses, liabilities, obligations, claims, contingencies, damages, costs and expenses, including all judgments, amounts paid in settlements, court costs and reasonable attorney’s fees and costs of investigation (collectively, “Losses”) that any such Purchaser Party may suffer or incur as a result of or relating to any misrepresentation, breach or inaccuracy of any representation, warranty, covenant or agreement made by the Company in any Transaction Document and (ii) reimburse each such Purchaser Party for its reasonable legal and other expenses (including the cost of any investigation, preparation and travel) incurred in connection therewith, as such expense are incurred.

4.7           Use of Proceeds. The Company shall use the net proceeds from the sale of the Securities hereunder for working capital purposes and not for the satisfaction of any portion of the Company’s debt (other than payment of trade payables and accrued expenses in the ordinary course of the Company’s business and prior practices), to redeem any capital stock of the Company or to settle any outstanding Action.

4.8           Limitations on Issuance of Future Priced Securities and Issuance of Securities. During the one year period following the Closing, the Company shall not issue any “Future Priced Securities” as such term is described by NASD IM 4350-1. From the date hereof until ninety (90) days after the Effective Date, neither the Company nor any Subsidiary shall, without the prior written consent of the Purchasers holding at least two-thirds of the Shares issued under this Agreement, issue shares of Common Stock or Common Stock Equivalents, other than (i) the

19

issuance of the Securities, (ii) the issuance of securities upon the exercise or conversion of any Common Stock or Common Stock Equivalents issued by the Company prior to the date hereof (not including any amendments, modifications and reissuances thereof), (iii) the grants of options or warrants, or the issuance of additional securities under any duly authorized Company stock option, restricted stock or stock purchase plan in effect as of the date hereof (not including any amendments, modifications and reissuances thereof), (iv) the issuance of securities pursuant to one or more Strategic Transactions and (v) the issuance of securities constituting less than one percent (1%) of the number of shares of Common Stock, outstanding on the date hereof; provided, however, that such ninety (90) day period following the Effective Date set forth in this Section 4.9 shall be extended for the number of Trading Days during such period in which (i) trading in the Common Stock is suspended by any Trading Market or (ii) a Registration Statement is not effective or the prospectus included in such Registration Statement may not be used by the Purchasers for the resale of the Shares and Warrant Shares. For purposes of this Section 4.9, the number of shares of Common Stock outstanding refers to the actual number of shares of Common Stock outstanding and does not include any outstanding Common Stock Equivalents.

4.9           Listing of Securities. The Company shall: (i) in the time and manner required by each Trading Market on which the Common Stock is listed, prepare and file with such Trading Market an additional shares listing application covering the Shares and Warrant Shares, (ii) take all steps necessary to cause such shares to be approved for listing on each Trading Market on which the Common Stock is listed as soon as possible thereafter, (iii) provide to each Purchaser evidence of such listing, and (iv) maintain the listing of such Shares on each such Trading Market or another eligible securities market.

At the Closing, the Company shall reimburse the fees and expenses of Lowenstein Sandler, PC, counsel for the Xmark funds, in the amount of $8,250 in connection with the negotiation of the Transaction Documents, it being understood that Lowenstein Sandler, PC has not rendered any legal advice to the Company in connection with the transactions contemplated hereby and that the Company has relied for such matters on the advice of its own counsel. Except as specified in the Registration Rights Agreement, each party shall pay the fees and expenses of its advisers, counsel, accountants and other experts, if any, and all other expenses incurred by such party incident to the negotiation, preparation, execution, delivery and performance of the Transaction Documents.  The Company shall pay all stamp and other taxes and duties levied in connection with the sale of the Securities.

No provision of this Agreement may be waived or amended except in a written instrument signed by the Company and Purchasers holding no less than two-thirds of the Shares issued or issuable under this Agreement.  The Company shall provide prior notice to all Purchasers of any proposed waiver or amendment.  No waiver of any default with respect to any provision, condition or requirement of this Agreement shall be deemed to be a continuing waiver in the future or a waiver of any subsequent default or a waiver of any other provision, condition or requirement hereof, nor shall any delay or omission of either party to exercise any right hereunder in any manner impair the exercise of any such right.

5.5           Construction. The headings herein are for convenience only, do not constitute a part of this Agreement and shall not be deemed to limit or affect any of the provisions hereof.  The language used in this Agreement will be deemed to be the language chosen by the parties to express their mutual intent, and no rules of strict construction will be applied against any party.  This Agreement shall be construed as if drafted jointly by the parties, and no

21

presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any provisions of this Agreement or any of the Transaction Documents.

5.6           Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the parties and their successors and permitted assigns.  The Company may not assign this Agreement or any rights or obligations hereunder without the prior written consent of the Purchasers holding no less than two-thirds of the Shares issued or issuable under this Agreement. Any Purchaser may assign any or all of its rights under this Agreement to any Person to whom such Purchaser assigns or transfers any Securities, provided such transferee agrees in writing to be bound, with respect to the transferred Securities, by the provisions hereof that apply to the “Purchasers.”

5.7           No Third-Party Beneficiaries. This Agreement is intended for the benefit of the parties hereto and their respective successors and permitted assigns and is not for the benefit of, nor may any provision hereof be enforced by, any other Person.

5.8           Governing Law. All questions concerning the construction, validity, enforcement and interpretation of this Agreement shall be governed by and construed and enforced in accordance with the internal laws of the State of California, without regard to the principles of conflicts of law thereof.  Each party agrees that all Proceedings concerning the interpretations, enforcement and defense of the transactions contemplated by this Agreement and any other Transaction Documents (whether brought against a party hereto or its respective Affiliates, employees or agents) may be commenced in the state and federal courts sitting in the City of San Francisco (the “California Courts”).  Each party hereto hereby irrevocably submits to the non-exclusive jurisdiction of the California Courts for the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein (including with respect to the enforcement of the any of the Transaction Documents), and hereby irrevocably waives, and agrees not to assert in any Proceeding, any claim that it is not personally subject to the jurisdiction of any such California Court, or that such Proceeding has been commenced in an improper or inconvenient forum.  Each party hereto hereby irrevocably waives personal service of process and consents to process being served in any such Proceeding by mailing a copy thereof via registered or certified mail or overnight delivery (with evidence of delivery) to such party at the address in effect for notices to it under this Agreement and agrees that such service shall constitute good and sufficient service of process and notice thereof.  Nothing contained herein shall be deemed to limit in any way any right to serve process in any manner permitted by law.  Each party hereto hereby irrevocably waives, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.  If either party shall commence a Proceeding to enforce any provisions of a Transaction Document, then the prevailing party in such Proceeding shall be reimbursed by the other party for its reasonable attorney’s fees and other costs and expenses incurred with the investigation, preparation and prosecution of such Proceeding.

5.9           Survival. The representations, warranties, agreements and covenants contained herein shall survive the Closing and the delivery of the Shares and Warrants.

22

5.10         Execution. This Agreement may be executed in two or more counterparts, all of which when taken together shall be considered one and the same agreement and shall become effective when counterparts have been signed by each party and delivered to the other party, it being understood that both parties need not sign the same counterpart.  In the event that any signature is delivered by facsimile transmission, such signature shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if such facsimile signature page were an original thereof.

5.11         Severability. If any provision of this Agreement is held to be invalid or unenforceable in any respect, the validity and enforceability of the remaining terms and provisions of this Agreement shall not in any way be affected or impaired thereby and the parties will attempt to agree upon a valid and enforceable provision that is a reasonable substitute therefor, and upon so agreeing, shall incorporate such substitute provision in this Agreement.

5.12         Replacement of Securities. If any certificate or instrument evidencing any Securities is mutilated, lost, stolen or destroyed, the Company shall issue or cause to be issued in exchange and substitution for and upon cancellation thereof, or in lieu of and substitution therefor, a new certificate or instrument, but only upon receipt of evidence reasonably satisfactory to the Company of such loss, theft or destruction and customary and reasonable indemnity, if requested.  The applicants for a new certificate or instrument under such circumstances shall also pay any reasonable third-party costs associated with the issuance of such replacement Securities.  If a replacement certificate or instrument evidencing any Securities is requested due to a mutilation thereof, the Company may require delivery of such mutilated certificate or instrument as a condition precedent to any issuance of a replacement.

5.13         Remedies. In addition to being entitled to exercise all rights provided herein or granted by law, including recovery of damages, each of the Purchasers and the Company will be entitled to specific performance under the Transaction Documents.  The parties agree that monetary damages may not be adequate compensation for any loss incurred by reason of any breach of obligations described in the foregoing sentence and hereby agrees to waive in any action for specific performance of any such obligation the defense that a remedy at law would be adequate.

5.14         Payment Set Aside. To the extent that the Company makes a payment or payments to any Purchaser pursuant to any Transaction Document or a Purchaser enforces or exercises its rights thereunder, and such payment or payments or the proceeds of such enforcement or exercise or any part thereof are subsequently invalidated, declared to be fraudulent or preferential, set aside, recovered from, disgorged by or are required to be refunded, repaid or otherwise restored to the Company, a trustee, receiver or any other Person under any law (including, without limitation, any bankruptcy law, state or federal law, common law or equitable cause of action), then to the extent of any such restoration the obligation or part thereof originally intended to be satisfied shall be revived and continued in full force and effect as if such payment had not been made or such enforcement or setoff had not occurred.

5.15         Independent Nature of Purchasers’ Obligations and Rights. The obligations of each Purchaser under any Transaction Document are several and not joint with the obligations of

23

any other Purchaser, and no Purchaser shall be responsible in any way for the performance of the obligations of any other Purchaser under any Transaction Document.  The decision of each Purchaser to purchase Securities pursuant to the Transaction Documents has been made by such Purchaser independently of any other Purchaser.  Nothing contained herein or in any Transaction Document, and no action taken by any Purchaser pursuant thereto, shall be deemed to constitute the Purchasers as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Purchasers are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by the Transaction Document.  Each Purchaser acknowledges that no other Purchaser has acted as agent for such Purchaser in connection with making its investment hereunder and that no Purchaser will be acting as agent of such Purchaser in connection with monitoring its investment in the Securities or enforcing its rights under the Transaction Documents.  Each Purchaser shall be entitled to independently protect and enforce its rights, including without limitation the rights arising out of this Agreement or out of the other Transaction Documents, and it shall not be necessary for any other Purchaser to be joined as an additional party in any proceeding for such purpose.

5.16         Obligations of Purchasers. The Company acknowledges that the obligations of each Purchaser under this Agreement are several and not joint with the obligations of any other Purchaser, and no Purchaser shall be responsible in any way for the performance of the obligations of any other Purchaser under this Agreement. The decision of each Purchaser to enter into to this Agreement has been made by such Purchaser independently of any other Purchaser. The Company further acknowledges that nothing contained in this Agreement, and no action taken by any Purchaser pursuant hereto, shall be deemed to constitute the Purchasers as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Purchasers are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated hereby. Each Purchaser shall be entitled to independently protect and enforce its rights, including without limitation, the rights arising out of this Agreement, and it shall not be necessary for any other Purchaser to be joined as an additional party in any proceeding for such purpose.

5.17         Legal Counsel. Each Purchaser has been represented by its own separate legal counsel in their review and negotiation of this Agreement and with respect to the transactions contemplated hereby. The Company has elected to provide all Purchasers with the same terms and Agreement for the convenience of the Company and not because it was required or requested to do so by the Purchasers. The Company acknowledges that such procedure with respect to this Agreement in no way creates a presumption that the Purchasers are in any way acting in concert or as a group with respect to this Agreement or the transactions contemplated hereby or thereby.
