      Confidential Information of the Company and its Subsidiaries and the Company’s
      and its Subsidiaries’ use of any Intellectual Property or Confidential
      Information owned by a third party, and, to the Company’s Knowledge, there is no
      valid basis for the same.





(e)           The
      consummation of the transactions contemplated hereby and by the other
      Transaction Documents will not result in the alteration, loss, impairment of
      or

      others within those entities, particularly during the period in which the
      Company’s most recently filed periodic report under the 1934 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

      contemplated by the Transaction Documents, any valid right, interest or claim
      against or upon


-15-


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 such Investor.





5.11           Prohibited
      Transactions.  During the last thirty (30) days prior to the date

      the
      Company and that each of the other Investors shall have an independent right
      to
      assert any claims against such Investor arising out of any breach or violation
      of the provisions of this Section 5.11.

      all
      material respects on the Closing Date with the same force and effect as if

      shall be true and correct in all respects when made, and shall be true and
      correct in all respects on the Closing Date with the same force and effect
      as if
      they had been made on and as of said date.  The Investors shall have

(i)           Upon
      the mutual written consent of the Company and the Investors;





(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
      an Investor (with respect to itself only) if any of the conditions set forth
      in
      Section 6.1 shall have become incapable of fulfillment, and shall not have
      been
      waived by the Investor; or





(iv)           By
      either the Company or any Investor (with respect to itself only) if the Closing

      rata portion of the Terminating Investor’s allocated portion of the total number

      portion of the Terminated Investor’s allocated portion of the Shares as
      otherwise agreed to among each of the other Investors electing to purchase
      a
      portion of the Terminated Investor’s allocated portion of the
      Shares).  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.  The
      Company will furnish to the Investors and/or their assignees such information
      relating to the Company and its Subsidiaries as from time to time may reasonably
      be requested by the 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 Company’s obligations to the Investors under
      the Transaction Documents.





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





7.5           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 Capital 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


-19-


Common
      Stock on the Nasdaq Capital 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.





7.6           Termination
      of Covenants.  The provisions of Sections 7.2 through 7.4 shall
      terminate and be of no further force and effect on 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.





7.7           Removal
      of Legends.  Upon the earlier of (i) registration for resale
      pursuant to the Registration Rights Agreement or (ii) Rule 144(k) becoming
      available the Company shall (A) deliver to the transfer agent for the Common
      Stock (the “Transfer Agent”) irrevocable instructions that the Transfer Agent
      shall reissue a certificate representing shares of Common Stock (or make
      available such shares in electronic format via DWAC) without legends upon
      receipt by such Transfer Agent of the legended certificates for such shares,
      together with either (1) a customary representation by the Investor that Rule
      144(k) applies to the shares of Common Stock represented thereby or (2) a
      statement by the Investor that such Investor 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 1933
      Act.  From and after the earlier of such dates, upon an Investor’s
      written request, the Company shall promptly cause certificates evidencing the
      Investor’s Securities to be replaced with certificates which do not bear such
      restrictive legends or to be replaced with unlegended shares made available
      electronically via DWAC, 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 an unlegended certificate (or electronic unlegended shares)
      to
      replace a previously issued legended certificate, if: (1) the unlegended
      certificate is not delivered (or unlegended electronic shares are not made
      available) to an Investor within three (3) Business Days of submission by that
      Investor of a legended certificate and supporting documentation to the Transfer
      Agent as provided above (a copy of which shall be given to the Company) and
      (2)
      prior to the time such unlegended certificate is received by the Investor (or
      unlegended electronic shares are made available to the Investor via DWAC),
      the
      Investor, or any third party on behalf of such Investor or for the Investor’s
      account, purchases (in an open market transaction or otherwise) shares of Common
      Stock to deliver in satisfaction of a sale by the Investor of shares represented
      by such certificate (a “Buy-In”), then the Company shall pay in cash to the
      Investor (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 Investor as a result of the sale to which such Buy-In
      relates.  The Investor shall provide the Company written notice
      indicating the amounts payable to the Investor in respect of the
      Buy-In.





7.8           Subsequent
      Equity Sales.  From the date hereof until such time as no Investor
      holds any of the Securities (but in no event beyond July 1, 2009), the Company
      shall be


-20-


prohibited
      from effecting or entering into an agreement to effect any Subsequent Financing
      involving a “Variable Rate Transaction”.  The term “Variable Rate
      Transaction” shall mean a transaction in which the Company issues or sells (i)
      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, 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.





7.9           Equal
      Treatment of Investors.  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 Investor by the Company and negotiated separately by each Investor, and
      is
      intended for the Company to treat the Investors as a class and shall not in
      any
      way be construed as the Investors acting in concert or as a group with respect
      to the purchase, disposition or voting of Securities or otherwise.





7.10          Right
      of First Refusal on Future Financings. From the date hereof until the first
      anniversary of the Closing Date, upon any financing by the Company of its Common
      Stock or Common Stock Equivalents at an effective price per share of $2.70
      or
      less (appropriately adjusted for any stock split, reverse stock split, stock
      dividend or other reclassification or combination of the Common Stock occurring
      after the date hereof), the primary purpose of which is the raising of capital
      (a “Subsequent Financing”), each Investor shall have the right to participate in
      such Subsequent Financing as provided herein.  At least five (5)
      Business Days prior to the closing of the Subsequent Financing, the Company
      shall deliver to each Investor a written notice of its intention to effect
      a
      Subsequent Financing (“Pre-Notice”), which Pre-Notice shall ask such Investor if
      it wants to review the details of such financing (such additional notice, a
      “Subsequent Financing Notice”).  Upon the request of an Investor, and
      only upon a request by such Investor, for a Subsequent Financing Notice, the
      Company shall promptly, but no later than one Business Day after such request,
      deliver a Subsequent Financing Notice to such Investor.  Any Investor
      who elects to receive a Subsequent Financing Notice shall keep the contents
      thereof confidential until the consummation or the abandonment of the Subsequent
      Financing.  The Subsequent Financing Notice shall describe in
      reasonable detail the proposed terms of such Subsequent Financing, the amount
      of
      proceeds intended to be raised thereunder, the Person with whom such Subsequent
      Financing is proposed to be effected, and attached to which shall be a term
      sheet or similar document relating thereto.  Each Investor shall
      notify the Company by 6:30 p.m. (New York City time) on the fifth (5th) Business
      Day
      after their receipt of the Subsequent Financing Notice of its willingness to
      provide the Subsequent Financing on the terms described in the Subsequent
      Financing Notice, subject to completion of mutually acceptable
      documentation.  If one or more Investors shall fail to so notify the
      Company of their willingness to participate in the Subsequent Financing, the
      Investors agreeing to participate in the


-21-


Subsequent
      Financing (the “Participating Investors”) shall have the right to provide all of
      the Subsequent Financing.  If one or more Investors fail to notify the
      Company of their willingness to provide all of the Subsequent Financing and
      the
      Participating Investors do not agree to provide all of the Subsequent Financing,
      the Company may effect the remaining portion of such Subsequent Financing on
      substantially the same terms and to the Persons set forth in the Subsequent
      Financing Notice; provided that the Company must provide the Investors with
      a
      second Subsequent Financing Notice, and the Investors will again have the right
      of first refusal set forth above in this Section 7.10, if the Subsequent
      Financing subject to the initial Subsequent Financing Notice is not consummated
      for any reason on the terms set forth in such Subsequent Financing Notice within
      60 Business Days after the date of the initial Subsequent Financing Notice
      with
      the Person identified in the Subsequent Financing Notice.  In the
      event the Company receives responses to Subsequent Financing Notices from
      Investors seeking to purchase more than the financing sought by the Company
      in
      the Subsequent Financing such Investors shall have the right to purchase their
      Pro Rata Portion (as defined below) of the Common Stock or Common Stock
      Equivalents to be issued in such Subsequent Financing.  “Pro Rata
      Portion” is the ratio of (x) the amount invested by such Investor pursuant to
      this Agreement (the “Subscription Amount”) and (y) the aggregate sum of all of
      the Subscription Amounts.  Notwithstanding the foregoing, this Section
      7.10 shall not apply in respect of the issuance of (a) shares of Common Stock
      or
      options to employees, consultants, officers or directors of the Company pursuant
      to any stock or option plan duly adopted by the Board of Directors of the
      Company or a majority of the members of a committee of non-employee directors
      established for such purpose and (b) securities upon the exercise of or
      conversion of any convertible securities, options or warrants issued and
      outstanding on the date of this Agreement, provided that such securities have
      not been amended since the date of this Agreement to increase the number of
      shares of Common Stock issuable thereunder or to lower the exercise or
      conversion price thereof.





8.        
         Survival and Indemnification.





8.1  Survival.  The
      representations, warranties, covenants and agreements contained in this
      Agreement shall survive the Closing of the transactions contemplated by this
      Agreement.





8.2  Indemnification.  The
      Company agrees to indemnify and hold harmless 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 thereof)
      (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


-22-


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 conflicts of interest 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.

      assets to another corporation without the prior written consent of the

      advice to funds affiliated with SRB Greenway Capital participating in this

      the
      transactions contemplated hereby, and that each of the Company and each Investor
      has relied for such matters on the advice of its own respective
      counsel.  Such expenses shall be paid not later than the
      Closing.  The Company shall reimburse the Investors upon demand for

      without limitation reimbursement of attorneys’ fees and disbursements, in
      connection


-24-


with
      any
      amendment, modification or waiver of this Agreement or the other Transaction
      Documents.  In the event that legal proceedings are commenced by any
      party to this Agreement against another party to this Agreement in connection
      with this Agreement or the other Transaction Documents, the party or parties
      which do not prevail in such proceedings shall severally, but not jointly,
      pay
      their pro rata share of the reasonable attorneys’ fees and other reasonable
      out-of-pocket costs and expenses incurred by the prevailing party in such
      proceedings.





9.6           Amendments
      and Waivers.  Any term of this Agreement may be amended and the
      observance of any term of this Agreement may be waived (either generally or
      in a
      particular instance and either retroactively or prospectively), only with the
      written consent of the Company and the Investors.  Any amendment or
      waiver effected in accordance with this paragraph shall be binding upon each
      holder of any Securities purchased under this Agreement at the time outstanding,
      each future holder of all such Securities, and the Company.





9.7           Publicity.  Except
      as set forth below, no public release or announcement concerning the
      transactions contemplated hereby shall be issued by the Company or the Investors
      without the prior consent of the Company (in the case of a release or
      announcement by the Investors) or the Investors (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 Investors, as the case may be, shall allow
      the
      Investors 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 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 copies of the
      Transaction Documents.  In addition, the Company will make such other
      filings and notices in the manner and time required by the SEC or
      Nasdaq.





9.8           Severability.  Any
      provision of this Agreement 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.





9.9           Entire
      Agreement.  This Agreement, including the Exhibits and the
      Disclosure Letter, and the other Transaction Documents constitute the entire
      agreement among the parties hereof with respect to the subject matter hereof
      and
      thereof and supersede all prior agreements and understandings, both oral and
      written, between the parties with respect to the subject matter hereof and
      thereof.


-25-





9.10            Further
      Assurances.  The parties shall execute and deliver all such
      further instruments and documents and take all such other actions as may
      reasonably be required to carry out the transactions contemplated hereby and
      to
      evidence the fulfillment of the agreements herein contained.





9.11            Governing
      Law; Consent to Jurisdiction; Waiver of Jury Trial.  This
      Agreement shall be governed by, and construed in accordance with, the internal
      laws of the State of New York without regard to the choice of law principles
      thereof.  Each of the parties hereto irrevocably submits to the
      exclusive jurisdiction of the courts of the State of New York located in New
      York County and the United States District Court for the Southern District
      of
      New York for the purpose of any suit, action, proceeding or judgment relating
      to
      or arising out of this Agreement and the transactions contemplated
      hereby.  Service of process in connection with any such suit, action
      or proceeding may be served on each party hereto anywhere in the world by the
      same methods as are specified for the giving of notices under this
      Agreement.  Each of the parties hereto irrevocably consents to the
      jurisdiction of any such court in any such suit, action or proceeding and to
      the
      laying of venue in such court.  Each party hereto irrevocably waives
      any objection to the laying of venue of any such suit, action or proceeding
      brought in such courts and irrevocably waives any claim that any such suit,
      action or proceeding brought in any such court has been brought in an
      inconvenient forum. **EACH OF THE PARTIES HERETO WAIVES ANY RIGHT TO
      REQUEST A TRIAL BY JURY IN ANY LITIGATION WITH RESPECT TO THIS AGREEMENT AND
      REPRESENTS THAT COUNSEL HAS BEEN CONSULTED SPECIFICALLY AS TO THIS
      WAIVER.**





9.12           Independent
      Nature of Investors' Obligations and Rights.  The obligations of
      each Investor under any Transaction Document are several and not joint with
      the
      obligations of any other Investor, and no Investor shall be responsible in
      any
      way for the performance of the obligations of any other Investor under any
      Transaction Document.  The decision of each Investor to purchase
      Securities pursuant to the Transaction Documents has been made by such Investor
      independently of any other Investor.  Nothing contained herein or in
      any Transaction Document, and no action taken by any Investor pursuant thereto,
      shall be deemed to constitute the Investors as a partnership, an association,
      a
      joint venture or any other kind of entity, or create a presumption that the
      Investors are in any way acting in concert or as a group with respect to such
      obligations or the transactions contemplated by the Transaction
      Documents.  Each Investor acknowledges that no other Investor has
      acted as agent for such Investor in connection with making its investment
      hereunder and that no Investor will be acting as agent of such Investor in
      connection with monitoring its investment in the Securities or enforcing its
      rights under the Transaction Documents.  Each Investor 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 Investor
      to
      be joined as an additional party in any proceeding for such
      purpose.  The Company acknowledges that each of the Investors has been
      provided with the same Transaction Documents for the purpose of closing a
      transaction with multiple Investors and not because it was required or requested
      to do so by any Investor.
