(z)            The equipment of the Company and its subsidiaries has been maintained in a manner consistent with that of a reasonably prudent owner and such equipment is in good working condition, reasonable wear and tear excepted, except where the failure to so maintain such equipment would not have a Material Adverse Effect.

(aa)         The Company and its subsidiaries carry, or are covered by, insurance in such amounts and covering such risks as is adequate for the conduct of their respective businesses and the value of their respective properties from insurers of recognized financial responsibility and as is customary for companies engaged in similar businesses in similar industries.  Neither the Company nor any of its subsidiaries (i) has

12

received notice from any insurer or agent of such insurer that substantial capital improvements or other material expenditures will have to be made in order to continue such insurance or (ii) has any reason to believe that it will not be able to renew its existing insurance coverage as and when such coverage expires or to obtain similar coverage from similar insurers at a cost that would not have a Material Adverse Effect.

(cc)         The Company and its subsidiaries own or possess adequate rights to use all material patents, patent rights, patent applications, trademarks, service marks, trade names, trademark registrations, service mark registrations, copyrights, inventions, know-how (including trade secrets and other unpatented and/or unpatentable proprietary of confidential information, systems or procedures) and licenses necessary for the conduct of their respective businesses and have no reason to believe that the conduct of their respective businesses will conflict with; and neither the Company nor any of its subsidiaries has received any notice of infringement of or conflict with asserted rights of others with respect to any of such intellectual property which, individually or in the aggregate, if the subject of an unfavorable decision, ruling or finding, would have a Material Adverse Effect.

(dd)         Neither the Company nor any of its subsidiaries is involved in any strike, job action or labor dispute with any group of employees that might be expected to have a Material Adverse Effect, and, to the Company’s knowledge, no such action or dispute is threatened.

(ff)           Except as set forth in the Private Placement Memorandum, the Company and each of its subsidiaries has filed by the due date (including any extensions thereof) all federal, state and local income and franchise tax returns required to be filed through the date hereof and has paid all taxes (including withholding taxes, penalties and interest, assessments, fees and other charges) due thereon, other than those being contested in good faith and for which adequate reserves have been taken; and no tax deficiency has been determined adversely to the Company or any of its subsidiaries which has had (nor does the Company have any knowledge of any tax deficiency which, if determined adversely to the Company or any of its subsidiaries, might have) a Material Adverse Effect.

14

Adverse Effect; there has been no material spill, discharge, leak, emission, injection, escape, dumping or release of any kind onto such property or into the environment surrounding such property of Hazardous Materials due to or caused by the Company or any of its subsidiaries or with respect to which the Company or any of its subsidiaries have knowledge, except for any such spill, discharge, leak, emission, injection, escape, dumping or release which would not have or would not be reasonably likely to have a Material Adverse Effect; and the terms “hazardous wastes”, “toxic wastes”, “hazardous substances” and shall have the meanings specified in any applicable local, state, federal and foreign laws or regulations with respect to environmental protection.

(jj)           Assuming the accuracy of the representations and warranties of the Placement Agent contained in the Placement Agency Agreement and of the Purchasers contained in Section 5 and the compliance of such parties with the agreements set forth herein and therein, it is not necessary, in connection with the issuance and sale of the Securities, in the manner contemplated by Transaction Documents and the Private Placement Memorandum, to register the Securities under the Securities Act.

(kk)         The Company or any of its Affiliates (as defined in Rule 501(b) of Regulation D) have not engaged, and will not engage, directly or indirectly in any form of general solicitation or general advertising in connection with the offering of the Securities (as those terms are used in Regulation D) under the Securities Act or in any manner involving a public offering within the meaning of Section 4(2); and the Company has not entered, and will not enter, into any arrangement or agreement with respect to the distribution of the Securities, except for the Placement Agency Agreement, this Agreement and the Registration Rights Agreement, and the Company agrees not to enter into any such arrangement or agreement.

(mm)       Neither the Company nor, to the Company’s knowledge, any of the Affiliates of the Company, has taken, directly or indirectly, any action designed to cause or result in, or which has constituted or which might reasonably be expected to constitute, the stabilization or manipulation of the price of the Securities to facilitate the sale or resale of such securities.

(nn)         The Company has not sold or issued any security of the same or similar class or series as any of the Securities or any security convertible into any of the Securities during the six-month period preceding the earlier of the date of this Agreement and the Closing Date, including any sales pursuant to Rule 144A, or Regulation D (other than shares issued in connection with the Merger or pursuant to employee benefit plans, qualified stock options plans or other employee compensation plans or pursuant to outstanding options, rights or warrants), and has no intention of making, and will not make, an offer or sale of such securities, for a period of six months after the date of the Purchase Agreement, except for the offering of Securities as contemplated by the Placement Agency Agreement, the Purchase Agreement and the Registration Rights Agreement.  As used in this paragraph, the terms “offer” and “sale” have the meanings specified in Section 2(a)(3) of the Securities Act.

(oo)         The Company will not offer or sell any of the Securities to any person who it does not reasonably believe is (i) a qualified institutional buyer as defined in Rule 144A or (ii) an “accredited investor” (as defined in Rule 501(a) of Regulation D of the Act.

(qq)         Except as described in the Private Placement Memorandum, no person will have, as a result of the transactions contemplated by the Transaction Documents, any valid right, interest or claim against or upon the Company, any subsidiary or a Purchaser for any commission, fee or other compensation pursuant to any agreement, arrangement or understanding entered into by or on behalf of the Company.

(rr)           Neither the Company nor any person acting on its behalf has provided the Purchasers or their agents or counsel with any information that constitutes or might constitute material, non-public information, other than the terms of the transactions contemplated hereby.  The Company acknowledges that the Purchasers will

16

be relying on the accuracy of this representation in effecting transactions in the securities of the Company.

(ss)         Each certificate signed by any officer of the Company and delivered to the Purchasers or counsel to the Purchasers shall be deemed to be a representation and warranty by the Company to the Purchasers as to the matters covered thereby.

7.                   Covenants.

(a)           Reasonable Best Efforts.  Each party hereto shall use its reasonable best efforts to timely satisfy each of the conditions to be satisfied by it as provided in Section 8 and Section 9 of this Agreement.

(b)           Form D and Blue Sky.  The Company agrees to file a Form D with respect to the Securities as required under Regulation D and to provide a copy thereof to the Purchasers promptly after such filing. The Company shall, on or before the Closing Date, take such action as the Company shall reasonably determine is necessary in order to obtain an exemption for or to qualify the Securities for, sale to the Purchasers at the Closing pursuant to this Agreement under applicable securities or “Blue Sky” laws of the states of the United States, and shall provide evidence of any such action so taken to the Purchasers on or prior to the Closing Date. The Company shall make all filings and reports relating to the offer and sale of the Securities required under applicable securities or “Blue Sky” laws of the states of the United States following the Closing Date.

(c)           Second Information Statement.  The Company shall use commercially reasonable efforts to effect the Charter Amendment as soon as practicable after the Closing.  Without limiting the generality of the foregoing, promptly following the Closing the Company shall respond to any Commission comments to the preliminary Second Information Statement and shall prepare and file with the Commission a definitive Second Information Statement meeting the requirements of Section 14(c) of the Exchange Act and the rules promulgated thereunder and shall promptly mail the Second Information Statement to the stockholders of the Company.  The Company will comply with Section 14(c) of the Exchange Act and the rules promulgated thereunder connection with the preparation and mailing of the Second Information Statement, and the Second Information Statement shall not, as of the date that the Second Information Statement (or any amendment thereof or supplement thereto) is first mailed to stockholders or at the effective date of the Charter Amendment, contain any statement which, at the time and in the light of the circumstances under which it is made, is false or misleading with respect to any material fact, or which omits to state any material fact necessary in order to make the statements therein not false or misleading or necessary to correct any statement in any earlier communication with respect to the same subject matter which has become false or misleading.  If the Company should discover at any time prior to the effectiveness of the Charter Amendment, any event relating to the Company or any of its subsidiaries or any of their respective affiliates, officers or directors that is required to be set forth in a supplement or amendment to the Second Information Statement, in addition to the

17

Company’s obligations under the Exchange Act, the Company will promptly inform the Purchasers thereof.

(d)           Certificate of Amendment.  The Company agrees to file the Certificate of Amendment described in the Private Placement Memorandum increasing the number of authorized shares of its common stock no later than two business days after the expiration of 20 calendar days following the Company’s distribution to all its stockholders (current as of the record date associated therewith) of the Second Information Statement.

(e)           Lock-Up.  Except for the issuance of (i) 100 shares of the Company’s Series A Convertible Preferred Stock and (ii) shares of Common Stock issuable upon the automatic conversion of such 100 shares of Series A Convertible Preferred Stock, during the period beginning from the date hereof and continuing to and including the date 60 days after the date hereof, the Company agrees not to offer, sell, contract to sell or otherwise dispose of, except as provided hereunder, any securities of the Company that are substantially similar to the Securities, including but not limited to any securities that are convertible into or exchangeable for, or that represent the right to receive, common stock or any such substantially similar securities (other than pursuant to employee equity compensation plans or upon the conversion or exchange of convertible or exchangeable securities outstanding as of, the date of this Agreement), without the prior written consent of the Placement Agents.

(f)            Legend Removal.  In connection with any sale or disposition of the Securities by a Purchaser pursuant to Rule 144 or pursuant to any other exemption under the Securities Act such that the transferee acquires freely tradable shares and upon compliance by the Purchaser with the requirements of this Agreement, the Company shall or, in the case of Common Stock, shall cause the transfer agent for the Common Stock (the “Transfer Agent”) to issue replacement certificates representing the Securities sold or disposed of without restrictive legends.  Upon the earlier of (i) registration for resale pursuant to the Registration Rights Agreement or (ii) the Shares becoming freely tradable by a non-affiliate pursuant to Rule 144 the Company shall (A) deliver to the Transfer Agent irrevocable instructions that the Transfer Agent shall reissue a certificate representing shares of Common Stock without legends upon receipt by such Transfer Agent of the legended certificates for such shares, together with either (1) a customary representation by the Purchaser that Rule 144 applies to the shares of Common Stock represented thereby or (2) a statement by the Purchaser that such Purchaser has sold the shares of Common Stock represented thereby in accordance with the Plan of Distribution contained in the Registration Statement, and (B) cause its counsel to deliver to the Transfer Agent one or more blanket opinions to the effect that the removal of such legends in such circumstances may be effected under the Securities Act.  From and after the earlier of such dates, upon a Purchaser’s written request, the Company shall promptly cause certificates evidencing the Purchaser’s Securities to be replaced with certificates which do not bear such restrictive legends.  When the Company is required to cause an unlegended certificate to replace a previously issued legended certificate, if: (1) the unlegended certificate is not delivered to a Purchaser within three (3) business days of submission by that Purchaser of a legended certificate and supporting documentation to

18

the Transfer Agent as provided above and (2) prior to the time such unlegended certificate is received by the Purchaser, the Purchaser, or any third party on behalf of such Purchaser or for the Purchaser’s account, purchases (in an open market transaction or otherwise) shares of Common Stock to deliver in satisfaction of a sale by the Purchaser of shares represented by such certificate (a “Buy-In”), then the Company shall pay in cash to the Purchaser (for costs incurred either directly by such Purchaser or on behalf of a third party) the amount by which the total purchase price paid for Common Stock as a result of the Buy-In (including brokerage commissions, if any) exceeds the proceeds received by such Purchaser as a result of the sale to which such Buy-In relates.  The Purchaser shall provide the Company written notice indicating the amounts payable to the Purchaser in respect of the Buy-In.

(g)           Subsequent Sales.  From the date hereof until ninety (90) days after the Closing Date, without the consent of the Required Holders (as defined below), neither the Company nor any Subsidiary shall issue shares of Common Stock or Common Stock Equivalents (as defined below). Notwithstanding the foregoing, the provisions of this Section 7(g) shall not apply to (i) the issuance of the Series A Convertible Preferred Stock pursuant to the terms of the Preferred Stock Purchase Agreement (as in effect on the date hereof) or the issuance of shares of Common Stock upon the automatic conversion of the Series A Convertible Preferred Stock pursuant to the Designations (as in effect on the date hereof); (ii) the issuance of Common Stock or Common Stock Equivalents upon the conversion or exercise of any securities of the Company or a subsidiary outstanding on the date hereof, provided that the terms of such security are not amended after the date hereof to decrease the exercise price or increase the Common Stock or Common Stock Equivalents receivable upon the exercise, conversion or exchange thereof or (iii) the issuance of any Common Stock or Common Stock Equivalents pursuant to any Company equity incentive plan approved by the Company’s stockholders and in place as of the date hereof.  As used herein, “Required Holders” means, (i) prior to Closing, (A) each Purchaser agreeing to purchase at least $1,000,000 of Securities and (B) the Purchasers agreeing to purchase a majority of the Securities to be sold hereunder and, (ii) after the Closing, (C) each Purchaser, or any transferee, holding at least 2,200,000 Shares (subject to adjustment for any stock split, reverse stock split or other similar transaction), and (D) the Purchasers, or their transferees, holding a majority of the Shares issued hereunder.  As used herein, “Common Stock Equivalents” means any securities of the Company or any subsidiary which would entitle the holder thereof to acquire at any time Common Stock, including without limitation, any debt, preferred stock, rights, options, warrants or other instrument that is at any time convertible into or exchangeable for, or otherwise entitles the holder thereof to receive, Common Stock.

(h)           Prohibition on Variable Rate Transactions.  From the date hereof until the earlier of (i) three years from the Closing Date or (ii) such time as no Purchaser holds any of the Securities, the Company shall be prohibited from effecting or entering into an agreement to effect any “Variable Rate Transaction”.  The term “Variable Rate Transaction” shall mean a transaction in which the Company (i) issues or sells any debt or equity securities that are convertible into, exchangeable or exercisable for, or include the right to receive additional shares of Common Stock either (A) at a conversion,

19

exercise or exchange rate or other price that is based upon and/or varies with the trading prices of or quotations for the shares of Common Stock at any time after the initial issuance of such debt or equity securities, or (B) with a conversion, exercise or exchange price that is subject to being reset at some future date after the initial issuance of such debt or equity security or upon the occurrence of specified or contingent events directly or indirectly related to the business of the Company or the market for the Common Stock or (ii) enters into any agreement, including, but not limited to, an equity line of credit, whereby the Company may sell securities at a future determined price.  For the avoidance of doubt, the issuance of a security which is subject to customary anti-dilution protections, including where the conversion, exercise or exchange price is subject to adjustment as a result of stock splits, reverse stock splits and other similar recapitalization or reclassification events, shall not be deemed to be a “Variable Rate Transaction.”

(i)            No Integration.  The Company shall not, and shall use its commercially reasonable 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 such that it would require stockholder approval prior to the closing of such other transaction unless stockholder approval is obtained before the closing of such subsequent transaction.

(j)            Equal Treatment of Purchasers.  No consideration shall be offered or paid to any person to amend or consent to a waiver or modification of any provision of any of the Transaction Documents unless the same consideration is also offered to all of the parties to the Transaction Documents.  For clarification purposes, this provision constitutes a separate right granted to each Purchaser by the Company and negotiated separately by each Purchaser, and is intended for the Company to treat the Purchasers as a class and shall not in any way be construed as the Purchasers acting in concert or as a group with respect to the purchase, disposition or voting of Securities or otherwise.

(k)           Publicity.  Except as set forth below, no public release or announcement concerning the transactions contemplated hereby shall be issued by the Company or the Purchasers without the prior consent of the Company (in the case of a release or announcement by the Purchasers) or the Purchasers (in the case of a release or announcement by the Company) (which consents shall not be unreasonably withheld), except as such release or announcement may be required by law or the applicable rules or regulations of any securities exchange or securities market, in which case the Company or the Purchasers, as the case may be, shall allow the Purchasers or the Company, as applicable, to the extent reasonably practicable in the circumstances, reasonable time to comment on such release or announcement in advance of such issuance.  By 8:30 a.m. (New York City time) on the trading day immediately following the Closing Date (the “Disclosure Deadline”), the Company shall issue a press release disclosing the consummation of the transactions contemplated by this Agreement.  No later than the fourth trading day following the Closing Date, the Company will file a Current Report on Form 8-K attaching the press release described in the foregoing sentence as well as

20

copies of the Transaction Documents.  In addition, the Company will make such other filings and notices in the manner and time required by the Commission.  From and after the Disclosure Deadline, no Purchaser shall be deemed to be in possession of any material non-public information relating to the Company and, subject to the other terms of this Agreement, shall be free to effect transactions in securities of the Company.

8.                   Conditions to the Company’s Obligation to Sell the Securities.  The obligation of the Company hereunder to issue and sell the Securities to the Purchasers at the Closing is subject to the satisfaction, at or before the Closing Date, of each of the following conditions thereto, provided that these conditions are for the Company’s sole benefit and may be waived by the Company at any time in its sole discretion:

(a)           receipt by the Company of same-day funds in the full amount of the Purchase Price for the Securities being purchased hereunder; and

(b)           the accuracy of the representations and warranties made by the Purchasers and the fulfillment of those undertakings by such Purchasers prior to the Closing.

(b)           The Company shall have obtained any and all consents, permits, approvals, registrations and waivers necessary or appropriate for consummation of the purchase and sale of the Securities and the consummation of the other transactions contemplated by the Transaction Documents, all of which shall be in full force and effect.

(a)                                  The Company agrees to indemnify and hold harmless each Purchaser and the directors, officers, employees and agents of each such Purchaser against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject, under the Securities Act, the Exchange Act or other federal or state statutory law or regulation, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of, are based upon or related to any untrue statement or alleged untrue statement of a material fact contained in the Private Placement Memorandum or the omission or alleged omission to state therein, in light of the circumstances under which they were made, a material fact necessary to make the statements therein not misleading, and agrees to reimburse each such indemnified party for any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim as such expenses are incurred.

(b)                                 Promptly after receipt by an indemnified party under subsection (a) above of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; but the failure so to notify the indemnifying party (i) will not relieve it from liability under subsection (a) above unless and to the extent it did not otherwise learn of such action and such failure results in forfeiture by the indemnifying party of substantial rights and defenses; and (ii) will not, in any event, relieve it from any liability which it may have to any indemnified party otherwise than under subsection (a) above.  In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and, after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such subsection for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation.  No indemnifying party shall, without the written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such action or claim and (ii) does not include a statement as to, or an admission of, fault, culpability or a failure to act, by or on behalf of any indemnified party.

(c)                                  If the indemnification provided for in this Section 11 is unavailable to or insufficient to hold harmless an indemnified party under subsection (a) above in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall have a joint and several obligation to

25

contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by such indemnifying party, on the one hand, and such indemnified party, on the other hand, from the offering of the Securities.  The relative benefits received by the Company shall be deemed to be equal to the total net proceeds from the offering of the Securities (before deducting expenses) received by the Company.  The relative benefits received by the Purchaser shall be deemed to be equal to the value of receiving the Securities.  The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this subsection (c) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim.  Notwithstanding the provisions of this subsection (c), no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

(d)                                 The obligations of the Company under this Section 11 shall be in addition to any liability which the Company may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls any Purchaser within the meaning of the Securities Act.
