      Schedule 4.9, each of the Company and each of its Subsidiaries has good and
      marketable title to its properties and assets, and good title to its leasehold
      interests, in each case subject to no mortgage, pledge, lien, lease, encumbrance
      or charge, other than:




(a)           those
      resulting from taxes which have not yet become delinquent;




(b)           minor
      liens and encumbrances which do not materially detract from the value of the
      property subject thereto or materially impair the operations of the Company
      or
      any of its Subsidiaries, so long as in each such case, such liens and
      encumbrances have no effect on the lien priority of the Purchaser in such
      property; and




(c)           those
      that have otherwise arisen in the ordinary course of business, so long as they
      have no effect on the lien priority of the Purchaser therein.

      facilities, machinery, equipment, fixtures, vehicles and other properties owned,
      leased or used by the Company and its Subsidiaries are in good operating
      condition and repair and are reasonably fit and usable for the purposes for

      Company and its Subsidiaries are in compliance with all material terms of each
      lease to which it is a party or is otherwise bound.

      secrets, licenses, information and other proprietary rights and processes
      necessary for its business as now conducted and, to the Company’s knowledge, as
      presently proposed to be conducted (the “Intellectual Property”), without any
      known infringement of the rights of others.  There are no outstanding
      options, licenses or agreements of any kind relating to the foregoing
      proprietary rights, nor is the Company or any of its Subsidiaries bound by
      or a
      party to any options, licenses or agreements of any kind with respect to the

      the Company nor any of its Subsidiaries has received any communications alleging
      that the Company or any of its Subsidiaries has violated any of the patents,
      trademarks, service marks, trade names, copyrights or trade secrets or other
      proprietary rights of any other person or entity, nor is the Company or any
      of

      with Other Instruments.  Neither the Company nor any of its
      Subsidiaries is in violation or default of (x) any term of its Charter or
      Bylaws, or (y) except as set forth on Schedule 4.11, any provision of any
      indebtedness, mortgage, indenture, contract, agreement or instrument to which
      it
      is party or by which it is bound or of any judgment, decree, order or writ,
      which violation or default, in the case of this clause (y), has had, or could
      reasonably be expected to have, either individually or in the aggregate, a
      Material Adverse Effect.  The execution, delivery and performance of
      and compliance with this Agreement and the Related Agreements to which it is
      a
      party, and the issuance and sale of the Note by the Company and the other
      Securities by the Company each pursuant hereto and thereto, will not, with
      or
      without the passage of time or giving of notice, result in any such material
      violation, or be in conflict with or constitute a default under any such term
      or
      provision, or result in the creation of any mortgage, pledge, lien, encumbrance
      or charge upon any of the properties or assets of the Company or any of its
      Subsidiaries or the suspension, revocation, impairment, forfeiture or nonrenewal
      of any permit, license, authorization or approval applicable to the Company,
      its
      business or operations or any of its assets or properties.




4.12           Litigation.  Except
      as set forth on Schedule 4.12 hereto, there is no action, suit, proceeding
      or
      investigation pending or, to the Company’s knowledge, currently threatened
      against the Company or any of its Subsidiaries that prevents the Company or
      any
      of its Subsidiaries from entering into this Agreement or the other Related
      Agreements, or from consummating the transactions contemplated hereby or
      thereby, or which has had, or could reasonably be expected to have, either
      individually or in the aggregate, a Material Adverse Effect or any change in
      the
      current equity ownership of the Company or any of its Subsidiaries, nor is
      the
      Company aware that there is any basis to assert any of the
      foregoing.  Neither the Company nor any of its Subsidiaries is a party
      to or subject to the provisions of any order, writ, injunction, judgment or
      decree of any court or government agency or instrumentality.  There is
      no action, suit, proceeding or investigation by the Company or any of its
      Subsidiaries currently pending or which the Company or any of its Subsidiaries
      intends to initiate.




4.13           Tax
      Returns and Payments.  Each of the Company and each of its
      Subsidiaries has timely filed all tax returns (federal, state and local)
      required to be filed by it.  All taxes shown to be due and payable on
      such returns, any assessments imposed, and all other taxes due and payable
      by
      the Company or any of its Subsidiaries on or before the Closing, have been
      paid
      or will be paid prior to the time they become delinquent.  Except as
      set forth on Schedule 4.13, neither the Company nor any of its Subsidiaries
      has been advised:




(a)           that
      any of its returns, federal, state or other, have been or are being audited
      as
      of the date hereof; or




(b)           of
      any adjustment, deficiency, assessment or court decision in respect of its
      federal, state or other taxes.




The
      Company has no knowledge of any liability for any tax to be imposed upon its
      properties or assets as of the date of this Agreement that is not adequately
      provided for.




10


4.14           Employees.  Except
      as set forth on Schedule 4.14, neither the Company nor any of its Subsidiaries
      has any collective bargaining agreements with any of its
      employees.  There is no labor union organizing activity pending or, to
      the Company’s knowledge, threatened with respect to the Company or any of its
      Subsidiaries.  Except as disclosed in the Exchange Act Filings or on
      Schedule 4.14, neither the Company nor any of its Subsidiaries is a party to
      or
      bound by any currently effective employment contract, deferred compensation
      arrangement, bonus plan, incentive plan, profit sharing plan, retirement
      agreement or other employee compensation plan or agreement.  To the
      Company’s knowledge, no employee of the Company or any of its Subsidiaries, nor
      any consultant with whom the Company or any of its Subsidiaries has contracted,
      is in violation of any term of any employment contract, proprietary information
      agreement or any other agreement relating to the right of any such individual
      to
      be employed by, or to contract with, the Company or any of its Subsidiaries
      because of the nature of the business to be conducted by the Company or any
      of
      its Subsidiaries; and to the Company’s knowledge the continued employment by the
      Company and its Subsidiaries of their present employees, and the performance
      of
      the Company’s and its Subsidiaries’ contracts with its independent contractors,
      will not result in any such violation.  Neither the Company nor any of
      its Subsidiaries is aware that any of its employees is obligated under any
      contract (including licenses, covenants or commitments of any nature) or other
      agreement, or subject to any judgment, decree or order of any court or
      administrative agency that would interfere with their duties to the Company
      or
      any of its Subsidiaries.  Neither the Company nor any of its
      Subsidiaries has received any notice alleging that any such violation has
      occurred.  Except for employees who have a current effective
      employment agreement with the Company or any of its Subsidiaries, no employee
      of
      the Company or any of its Subsidiaries has been granted the right to continued
      employment by the Company or any of its Subsidiaries or to any material
      compensation following termination of employment with the Company or any of
      its
      Subsidiaries.  Except as set forth on Schedule 4.14, the Company is
      not aware that any officer, key employee or group of employees intends to
      terminate his, her or their employment with the Company or any of its
      Subsidiaries, nor does the Company or any of its Subsidiaries have a present
      intention to terminate the employment of any officer, key employee or group
      of
      employees.




4.15           Registration
      Rights and Voting Rights.  Except as set forth on
      Schedule 4.15 and except as disclosed in Exchange Act Filings, neither the
      Company nor any of its Subsidiaries is presently under any obligation, and
      neither the Company nor any of its Subsidiaries has granted any rights, to
      register any of the Company’s or its Subsidiaries’ presently outstanding
      securities or any of its securities that may hereafter be
      issued.  Except as set forth on Schedule 4.15 and except as disclosed
      in Exchange Act Filings, to the Company’s knowledge, no stockholder of the
      Company or any of its Subsidiaries has entered into any agreement with respect
      to the voting of equity securities of the Company or any of its
      Subsidiaries.




4.16           Compliance
      with Laws; Permits.  Neither the Company nor any of its
      Subsidiaries is in violation of any provision of the Sarbanes-Oxley Act of
      2002
      or any SEC related regulation or rule or any rule of the Principal Market (as
      hereafter defined) promulgated thereunder or any other applicable statute,
      rule,
      regulation, order or restriction of any domestic or foreign government or any
      instrumentality or agency thereof in respect of the conduct of its business
      or
      the ownership of its properties which has had, or could reasonably be expected
      to have, either individually or in the aggregate, a Material Adverse
      Effect.  No governmental orders, permissions, consents, approvals or
      authorizations are required to be obtained and no registrations or declarations
      are required to be filed in connection with the execution and delivery of this
      Agreement or any other Related Agreement and the issuance of any of the
      Securities, except such as have been duly and validly obtained or filed, or
      with
      respect to any filings that must be made after the Closing, as will be filed
      in
      a timely manner.  Each of the Company and its Subsidiaries has all
      material franchises, permits, licenses and any similar authority necessary
      for
      the conduct of its business as now being conducted by it, the lack of which
      could, either individually or in the aggregate, reasonably be expected to have
      a
      Material Adverse Effect.




11


4.17           Environmental
      and Safety Laws.  Neither the Company nor any of its Subsidiaries
      is in violation of any applicable statute, law or regulation relating to the
      environment or occupational health and safety, and to its knowledge, no material
      expenditures are or will be required in order to comply with any such existing
      statute, law or regulation.  Except as set forth on Schedule 4.17, no
      Hazardous Materials (as defined below) are used or have been used, stored,
      or
      disposed of by the Company or any of its Subsidiaries or, to the Company’s
      knowledge, by any other person or entity on any property owned, leased or used
      by the Company or any of its Subsidiaries.  For the purposes of the
      preceding sentence, “Hazardous Materials” shall mean:




(a)           materials
      which are listed or otherwise defined as “hazardous” or “toxic” under any
      applicable local, state, federal and/or foreign laws and regulations that govern
      the existence and/or remedy of contamination on property, the protection of
      the
      environment from contamination, the control of hazardous wastes, or other
      activities involving hazardous substances, including building materials;
      or




(b)           any
      petroleum products or nuclear materials.




4.18           Valid
      Offering.  Assuming the accuracy of the representations and
      warranties of the Purchaser contained in this Agreement, the offer, sale and
      issuance of the Securities will be exempt from the registration requirements
      of
      the Securities Act of 1933, as amended (the “Securities Act”), and will have
      been registered or qualified (or are exempt from registration and qualification)
      under the registration, permit or qualification requirements of all applicable
      state securities laws.




4.19           Full
      Disclosure.  Each of the Company and each of its Subsidiaries has
      provided the Purchaser with all information requested by the Purchaser in
      connection with its decision to purchase the Note and Warrant, including all
      information the Company and its Subsidiaries believe is reasonably necessary
      to
      make such investment decision.  Neither this Agreement, the Related
      Agreements, the exhibits and schedules hereto and thereto nor any other document
      delivered by the Company or any of its Subsidiaries to Purchaser or its
      attorneys or agents in connection herewith or therewith or with the transactions
      contemplated hereby or thereby, contain any untrue statement of a material
      fact
      nor omit to state a material fact necessary in order to make the statements
      contained herein or therein, in light of the circumstances in which they are
      made, not misleading.  Any financial projections and other estimates
      provided to the Purchaser by the Company or any of its Subsidiaries were based
      on the Company’s and its Subsidiaries’ experience in the industry and on
      assumptions of fact and opinion as to future events which the Company or any
      of
      its Subsidiaries, at the date of the issuance of such projections or estimates,
      believed to be reasonable.




12


4.20           Insurance.  Each
      of the Company and each of its Subsidiaries has general commercial, product
      liability, fire and casualty insurance policies with coverages which the Company
      believes are customary for companies similarly situated to the Company and
      its
      Subsidiaries in the same or similar business.




4.21           SEC
      Reports.  Except as set forth on Schedule 4.21, the Company has
      filed all proxy statements, reports and other documents required to be filed
      by
      it under the Securities Exchange Act 1934, as amended (the “Exchange
      Act”).  The Company has furnished the Purchaser copies
      of:  (i) its Annual Reports on Form 10-K for its fiscal years ended
      December 31, 2006; and (ii) the Form 8-K filings which it has made during the
      fiscal year 2007 to date (collectively, the “SEC Reports”).  Except as
      set forth on Schedule 4.21, each SEC Report was, at the time of its filing,
      in
      substantial compliance with the requirements of its respective form and none
      of
      the SEC Reports, nor the financial statements (and the notes thereto) included
      in the SEC Reports, as of their respective filing dates, contained any untrue
      statement of a material fact or omitted to state a material fact required to
      be
      stated therein or necessary to make the statements therein, in light of the
      circumstances under which they were made, not misleading.




4.22           Listing.  The
      Company’s Common Stock is listed or quoted, as applicable, on a Principal Market
      (as hereafter defined) and satisfies and at all times hereafter will satisfy,
      all requirements for the continuation of such listing or quotation, as
      applicable.  The Company has not received any notice that its Common
      Stock will be delisted from, or no longer quoted on, as applicable, the
      Principal Market or that its Common Stock does not meet all requirements for
      such listing or quotation, as applicable.  For purposes hereof, the
      term “Principal Market” means the NASD Over The Counter Bulletin Board, NASDAQ
      Capital Market, NASDAQ National Markets System, American Stock Exchange or
      New
      York Stock Exchange (whichever of the foregoing is at the time the principal
      trading exchange or market for the Common Stock).




4.23           No
      Integrated Offering.  Neither the Company, nor any of its
      Subsidiaries or affiliates, nor any person acting on its or their behalf, has
      directly or indirectly made any offers or sales of any security or solicited
      any
      offers to buy any security under circumstances that would cause the offering
      of
      the Securities pursuant to this Agreement or any of the Related Agreements
      to be
      integrated with prior offerings by the Company for purposes of the Securities
      Act which would prevent the Company from selling the Securities pursuant to
      Rule
      506 under the Securities Act, or any applicable exchange-related stockholder
      approval provisions, nor will the Company or any of its affiliates or
      Subsidiaries take any action or steps that would cause the offering of the
      Securities to be integrated with other offerings.




4.24           Stop
      Transfer.  The Securities are restricted securities as of the date
      of this Agreement.  Neither the Company nor any of its Subsidiaries
      will issue any stop transfer order or other order impeding the sale and delivery
      of any of the Securities at such time as the Securities are registered for
      public sale or an exemption from registration is available, except as required
      by state and federal securities laws.




4.25           Dilution.  The
      Company specifically acknowledges that its obligation to issue the shares of
      Common Stock upon exercise of the Warrants are  binding upon the
      Company and enforceable regardless of the dilution such issuance may have on
      the
      ownership interests of other shareholders of the Company.




13


4.26           Patriot
      Act.   The Company certifies that, to the best of Company’s
      knowledge, neither the Company nor any of its Subsidiaries has been designated,
      nor is or shall be owned or controlled, by a “suspected terrorist” as defined in
      Executive Order 13224.  The Company hereby acknowledges that the
      Purchaser seeks to comply with all applicable laws concerning money laundering
      and related activities.  In furtherance of those efforts, the Company
      hereby represents, warrants and covenants that:  (i) none of the cash
      or property that the Company or any of its Subsidiaries will pay or will
      contribute to the Purchaser has been or shall be derived from, or related to,
      any activity that is deemed criminal under United States law; and (ii) no
      contribution or payment by the Company or any of its Subsidiaries to the
      Purchaser, to the extent that they are within the Company’s and/or its
      Subsidiaries’ control shall cause the Purchaser to be in violation of the United
      States Bank Secrecy Act, the United States International Money Laundering
      Control Act of 1986 or the United States International Money Laundering
      Abatement and Anti-Terrorist Financing Act of 2001.  The Company shall
      promptly notify the Purchaser if any of these representations, warranties or
      covenants ceases to be true and accurate regarding the Company or any of its
      Subsidiaries.  The Company shall provide the Purchaser all additional
      information regarding the Company or any of its Subsidiaries that the Purchaser
      deems necessary or convenient to ensure compliance with all applicable laws
      concerning money laundering and similar activities.  The Company
      understands and agrees that if at any time it is discovered that any of the
      foregoing representations, warranties or covenants are incorrect, or if
      otherwise required by applicable law or regulation related to money laundering
      or similar activities, the Purchaser may undertake appropriate actions to ensure
      compliance with applicable law or regulation, including but not limited to
      segregation and/or redemption of the Purchaser’s investment in the
      Company.  The Company further understands that the Purchaser may
      release confidential information about the Company and its Subsidiaries and,
      if
      applicable, any underlying beneficial owners, to proper authorities if the
      Purchaser, in its sole discretion, determines that it is in the best interests
      of the Purchaser in light of relevant rules and regulations under the laws
      set
      forth in subsection (ii) above.




4.27           ERISA.  Based
      upon the Employee Retirement Income Security Act of 1974 (“ERISA”), and
      the regulations and published interpretations thereunder:  (i) neither
      the Company nor any of its Subsidiaries has engaged in any Prohibited
      Transactions (as defined in Section 406 of ERISA and Section 4975 of theInternal
      Revenue Code of 1986, as amended (the “Code”)); (ii) each of the Company
      and each of its Subsidiaries has met all applicable minimum funding requirements
      under Section 302 of ERISA in respect of its plans; (iii) neither the Company
      nor any of its Subsidiaries has any knowledge of any event or occurrence which
      would cause the Pension Benefit Guaranty Corporation to institute proceedings
      under Title IV of ERISA to terminate any employee benefit plan(s); (iv) neither
      the Company nor any of its Subsidiaries has any fiduciary responsibility for
      investments with respect to any plan existing for the benefit of persons other
      than the Company’s or such Subsidiary’s employees; and (v) neither the Company
      nor any of its Subsidiaries has withdrawn, completely or partially, from any
      multi-employer pension plan so as to incur liability under the Multiemployer
      Pension Plan Amendments Act of 1980.

5.           Representations
      and Warranties of the Purchaser.  The Purchaser hereby represents
      and warrants to the Company as follows (such representations and warranties
      do
      not lessen or obviate the representations and warranties of the Company set
      forth in this Agreement):




5.1           No
      Shorting.  The Purchaser or any of its affiliates and investment
      partners has not, will not and will not cause any person or entity, to directly

      be outstanding.

      Power and Authority.  The Purchaser has all necessary power and
      authority under all applicable provisions of law to execute and deliver this

      provisions.  All corporate action on the Purchaser’s part required for
      the lawful execution and delivery of this Agreement and the Related Agreements
      have been or will be effectively taken prior to the Closing.  Upon
      their execution and delivery, this Agreement and the Related Agreements will
      be
      valid and binding obligations of the Purchaser, enforceable in accordance with
      their terms, except:




(a)           as
      limited by applicable bankruptcy, insolvency, reorganization, moratorium or
      other laws of general application affecting enforcement of creditors’ rights;
      and




(b)           as
      limited by general principles of equity that restrict the availability of
      equitable and legal remedies.




5.3           Investment
      Representations.  The Purchaser understands that the Securities
      are being offered and sold pursuant to an exemption from registration contained
      in the Securities Act based in part upon the Purchaser’s representations
      contained in this Agreement, including, without limitation, that the Purchaser
      is an “accredited investor” within the meaning of Regulation D under the
      Securities Act of 1933, as amended (the “Securities Act”).  The
      Purchaser confirms that it has received or has had full access to all the
      information it considers necessary or appropriate to make an informed investment
      decision with respect to the Note and the Warrants to be purchased by it under
      this Agreement and the Warrant Shares acquired by it upon the exercise of the
      Warrants, respectively.  The Purchaser further confirms that it has
      had an opportunity to ask questions and receive answers from the Company
      regarding the Company’s and its Subsidiaries’ business, management and financial
      affairs and the terms and conditions of the Offering, the Note, the Warrants
      and

      The Company shall bear the full risk of loss from any loss of any nature

      and
      Security Agreement and the Security Agreement, (as defined in the Reaffirmation
      Agreement) and each other security agreement entered into by the Company and/or
      any of its Subsidiaries for the benefit of the Purchaser) and the Company and

      interruption, and such other hazards as the Purchaser shall specify in amounts
      and under insurance policies and bonds by insurers acceptable to the Purchaser
      and all premiums thereon shall be paid by the Company and the policies delivered
      to the Purchaser.  If the Company or any of its Subsidiaries fails to
      obtain the insurance and in such amounts of coverage as otherwise required
      pursuant to this Section 6.8, the Purchaser may procure such insurance and
      the
      cost thereof shall be promptly reimbursed by the Company and shall constitute
      Obligations.




19


(ii)           The
      Company’s insurance coverage shall not be impaired or invalidated by any act or
      neglect of the Company or any of its Subsidiaries and the insurer will provide
      the Purchaser with no less than thirty (30) days notice prior of
      cancellation;




(iii)           The
      Purchaser, in connection with its status as a lender loss payee, will be

6.9           Intellectual
      Property.  Each of the Company and each of its Subsidiaries shall
      maintain in full force and effect its existence, rights and franchises and

      it
      and reasonably deemed to be necessary to the conduct of its
      business.




6.10           Properties.  Each

      time to time make all needful and proper repairs, renewals, replacements,
      additions and improvements thereto; and, except as set forth on Schedule 6.10
      hereto, each of the Company and each of its Subsidiaries will at all times
      comply with each provision of all leases to which it is a party or under which
      it occupies property if the breach of such provision could, either individually
      or in the aggregate, reasonably be expected to have a Material Adverse
      Effect.




6.11           Confidentiality.  The
      Company will not, and will not permit any of its Subsidiaries to, disclose,
      and
      will not include in any public announcement, the name of the Purchaser, unless
      expressly agreed to by the Purchaser or unless and until such disclosure is
      required by law or applicable regulation, and then only to the extent of such
      requirement.  Notwithstanding the foregoing, the Company may disclose
      the Purchaser’s identity and the terms of this Agreement to its current and

(c)           become
      subject to (including, without limitation, by way of amendment to or

      perform the provisions of this Agreement, any Related Agreement or any of the
      agreements contemplated hereby or thereby;

      the
      Company nor any of its Subsidiaries shall at any time take any action or
      otherwise acquire any interest in any asset or property to the extent the effect

      be a “United States real property holding corporation” as such term is defined
      in Section 897(c)(2) of the Code and Treasury Regulation Section 1.897-2

7.           Covenants
      of the Purchaser.  The Purchaser covenants and agrees with the
      Company as follows:




7.1           Confidentiality.  The
      Purchaser will not disclose, and will not include in any public announcement,
      the name of the Company, unless expressly agreed to by the Company or unless
      and
      until such disclosure is required by law or applicable regulation, and then
      only
      to the extent of such requirement.




7.2           Non-Public
      Information.  The Purchaser will not effect any sales in the
      shares of the Company’s Common Stock while in possession of material, non-public
      information regarding the Company if such sales would violate applicable
      securities law.




7.3           Limitation
      on Acquisition of Common Stock of the Company.  Notwithstanding
      anything to the contrary contained in this Agreement, any Related Agreement
      or
      any document, instrument or agreement entered into in connection with any other
      transactions between the Purchaser and the Company, the Purchaser may not
      acquire stock in the Company (including, without limitation, pursuant to a
      contract to purchase, by exercising an option or warrant, by converting any
      other security or instrument, by acquiring or exercising any other right to
      acquire, shares of stock or other security convertible into shares of stock
      in
      the Company, or otherwise, and such contracts, options, warrants, conversion
      or
      other rights shall not be enforceable or exercisable) to the extent such stock
      acquisition would cause any interest (including any original issue discount)
      payable by the Company to the Purchaser not to qualify as “portfolio interest”
within the meaning of Section 881(c)(2) of the Code, by reason of
      Section 881(c)(3) of the Code, taking into account the constructive
      ownership rules under Section 871(h)(3)(C) of the Code (the “Stock Acquisition
      Limitation”).  The Stock Acquisition Limitation shall automatically
      become null and void without any notice to the Company upon the earlier to
      occur
      of either (a) the Company’s delivery to the Purchaser of a Notice of Redemption
      (as defined in the Note) or (b) the existence of an Event of Default (as defined
      in the Note) at a time when the average closing price of the Company’s common
      stock as reported by Bloomberg, L.P. on the Principal Market for the immediately
      preceding five trading days is greater than or equal to 150% of the Exercise
      Price (as defined in the Warrants).




8.           Covenants
      of the Company and the Purchaser Regarding Indemnification.




8.1           Company
      Indemnification.  The Company agrees to indemnify, hold harmless,
      reimburse and defend the Purchaser, each of the Purchaser’s officers, directors,

      claims, costs, expenses, liabilities, obligations, losses or damages (including
      reasonable legal fees) of any nature, incurred by or imposed upon the Purchaser
      which result, arise out of or are based upon: (i) any misrepresentation by
      the
      Company or any of its Subsidiaries or breach of any warranty by the Company
      or
      any of its Subsidiaries in this Agreement, any other Related Agreement or in
      any
      exhibits or schedules attached hereto or thereto; or (ii) any breach or default
      in performance by Company or any of its Subsidiaries of any covenant or
      undertaking to be performed by Company or any of its Subsidiaries hereunder,
      under any other Related Agreement or any other agreement entered into by the
      Company and/or any of its Subsidiaries and the Purchaser relating hereto or
      thereto.




24


8.2           Purchaser’s
      Indemnification.  The Purchaser agrees to indemnify, hold
      harmless, reimburse and defend the Company and each of the Company’s officers,
      directors, agents, affiliates, control persons and principal shareholders,
      at
      all times against any claims, costs, expenses, liabilities, obligations, losses
      or damages (including reasonable legal fees) of any nature, incurred by or
      imposed upon the Company which result, arise out of or are based
      upon:  (i) any misrepresentation by the Purchaser or breach of any
      warranty by the Purchaser in this Agreement or in any exhibits or schedules
      attached hereto or any Related Agreement; or (ii) any breach or default in
      performance by the Purchaser of any covenant or undertaking to be performed
      by
      the Purchaser hereunder, or any other agreement entered into by the Company
      and
      the Purchaser relating hereto.




9.           Exercise
      of the Warrants.




9.1           Mechanics
      of Exercise.




(a)           Provided
      the Purchaser has notified the Company of the Purchaser’s intention to sell the
      Warrant Shares and the Warrant Shares are included in an effective registration
      statement or are otherwise exempt from registration when sold:  (i)
      upon the exercise of the Warrants or part thereof, the Company shall, at its
      own
      cost and expense, take all necessary action (including the issuance of an
      opinion of counsel reasonably acceptable to the Purchaser following a request
      by
      the Purchaser) to assure that the Company’s transfer agent shall issue shares of
      the Company’s Common Stock in the name of the Purchaser (or its nominee) or such
      other persons as designated by the Purchaser in accordance with Section 9.1(b)
      hereof and in such denominations to be specified representing the number of
      Warrant Shares issuable upon such exercise; and (ii) the Company warrants
      that no instructions other than these instructions have been or will be given
      to
      the transfer agent of the Company’s Common Stock and that after the
      effectiveness date of a registration statement filed pursuant to the Securities
      Act the Warrant Shares issued will be freely transferable subject to the
      prospectus delivery requirements of the Securities Act and the provisions of
      this Agreement, and will not contain a legend restricting the resale or
      transferability of the Warrant Shares.




(b)           The
      Purchaser will give notice of its decision to exercise its right to exercise
      the
      Warrants or part thereof by faxing or otherwise delivering an executed and
      completed notice of the number of shares to be subscribed to the Company (the
      “Form of Subscription”).  The Purchaser will not be required to
      surrender the Warrants until the Purchaser receives a credit to the account
      of
      the Purchaser’s prime broker through the DWAC system (as defined below),
      representing the Warrant Shares or until the Warrants have been fully
      exercised.  Each date on which a Form of Subscription is faxed or
      delivered to the Company in accordance with the provisions hereof shall be
      deemed a “Exercise Date.”  Pursuant to the terms of the Form of
      Subscription, the Company will issue instructions to the transfer agent
      accompanied by an opinion of counsel within one (1) business day of the date
      of
      the delivery to the Company of the  Form of Subscription and shall
      cause the transfer agent to transmit the certificates representing the Warrant
      Shares set forth in the applicable Form of Subscription to the Holder by
      crediting the account of the Purchaser’s prime broker with the Depository Trust
      Company (“DTC”) through its Deposit Withdrawal Agent Commission (“DWAC”) system
      within three (3) business days after receipt by the Company of the Form of
      Subscription (the “Delivery Date”).




25


(c)           The
      Company understands that a delay in the delivery of the Warrant Shares in the
      form required pursuant to Section 9 hereof beyond the Delivery Date could result
      in economic loss to the Purchaser.  In the event that the Company
      fails to direct its transfer agent to deliver the Warrant Shares to the
      Purchaser via the DWAC system within the time frame set forth in Section 9.1(b)
      above and the Warrant Shares are not delivered to the Purchaser by the Delivery
      Date, as compensation to the Purchaser for such loss, the Company agrees to
      pay
      late payments to the Purchaser for late issuance of the Warrant Shares in the
      form required pursuant to Section 9 hereof upon exercise of the Warrant in
      the
      amount equal to the greater of:  (i) $500 per business day after the
      Delivery Date; or (ii) the Purchaser’s actual damages from such delayed
      delivery.  The Company shall pay any payments incurred under this
      Section in immediately available funds upon demand and, in the case of actual
      damages, accompanied by reasonable documentation of the amount of such
      damages.  Such documentation shall show the number of shares of Common
      Stock the Purchaser is forced to purchase (in an open market transaction) which
      the Purchaser anticipated receiving upon such exercise, and shall be calculated
      as the amount by which (A) the Purchaser’s total purchase price (including
      customary brokerage commissions, if any) for the shares of Common Stock so
      purchased exceeds (B) the aggregate amount of the Exercise Price for the
      Warrants, for which such Form of Subscription was not timely
      honored.




10.           Offering
      Restrictions.  Except as previously disclosed in the SEC Reports
      or in the Exchange Act Filings, or stock or stock options granted to employees
      or directors of the Company (these exceptions hereinafter referred to as the
      “Excepted Issuances”), neither the Company nor any of its Subsidiaries will,
      prior to the full repayment of the Note (together with all accrued and unpaid
      interest and fees related thereto), (x) enter into any equity line of credit
      agreement or similar agreement or (y) issue, or enter into any agreement to
      issue, any securities with a variable/floating conversion and/or pricing feature
      which are or could be (by conversion or registration) free-trading securities
      (i.e.  common stock subject to a registration statement).




11.           Miscellaneous.




11.1           Governing
      Law, Jurisdiction and Waiver of Jury Trial.

      COMMENCED IN ANY SUCH COURT, AND THE COMPANY HEREBY WAIVES ANY OBJECTION THAT
      IT
      MAY HAVE BASED UPON LACK OF PERSONAL JURISDICTION, IMPROPER VENUE OR FORUM

      EARLIER OF THE COMPANY’S ACTUAL RECEIPT THEREOF OR THREE (3) DAYS AFTER DEPOSIT
      IN THE U.S. MAILS, PROPER POSTAGE PREPAID.




(c)           THE
      PARTIES DESIRE THAT THEIR DISPUTES BE RESOLVED BY A JUDGE APPLYING SUCH
      APPLICABLE LAWS.  THEREFORE, TO ACHIEVE THE BEST COMBINATION OF THE
      BENEFITS OF THE JUDICIAL SYSTEM AND OF ARBITRATION, THE PARTIES HERETO WAIVE

      THIS
      AGREEMENT, ANY OTHER RELATED AGREEMENT OR THE TRANSACTIONS RELATED HERETO OR

      be
      interpreted in such manner as to be effective and valid under applicable law,

      ineffective to the extent of such prohibition or invalidity or illegality,
      without invalidating the remainder of such provision or the remaining provisions
      thereof which shall not in any way be affected or impaired thereby.




27


11.3           Survival.  The
      representations, warranties, covenants and agreements made herein shall survive
      any investigation made by the Purchaser and the closing of the transactions
      contemplated hereby to the extent provided therein.  All statements as
      to factual matters contained in any certificate or other instrument delivered
      by
      or on behalf of the Company pursuant hereto in connection with the transactions
      contemplated hereby shall be deemed to be representations and warranties by
      the
      Company hereunder solely as of the date of such certificate or
      instrument.  All indemnities set forth herein shall survive the
      execution, delivery and termination of this Agreement and the Note and the
      making and repayment of the obligations arising hereunder, under the Note and
      under the other Related Agreements.




11.4           Successors.  Except
      as otherwise expressly provided herein, the provisions hereof shall inure to
      the
      benefit of, and be binding upon, the successors, heirs, executors and

      from time to time, other than the holders of Common Stock which has been sold
      by
      the Purchaser pursuant to Rule 144 or an effective registration
      statement.  The Purchaser may assign any or all of its rights
      hereunder or under any Related Agreement to any person and any such assignee
      shall succeed to the Purchaser’s rights with respect thereto; provided that the
      Purchaser shall not be permitted to effect any such assignment to a competitor
      of any Company unless an Event of Default (as defined in the Note) has occurred
      and is continuing.  Upon such assignment, the Purchaser shall be
      released from all responsibility for the Collateral (as defined in the Master
      Security Agreement, the Stock Pledge Agreement and each other security
      agreement, mortgage, cash collateral deposit letter, pledge and other agreements
      which are executed by the Company or any of its Subsidiaries in favor of the

      the
      Purchaser and such holder, be entitled to the same benefits as the Purchaser
      with respect to any security for the Obligations (as defined in the Master
      Security Agreement) in which such holder is a participant.  The
      Company agrees that each such holder may exercise any and all rights of banker's
      lien, set-off and counterclaim with respect to its participation in the
      Obligations (as defined in the Master Security Agreement) as fully as though
      the
      Company were directly indebted to such holder in the amount of such
      participation.  The Company may not assign any of its rights or
      obligations hereunder without the prior written consent of the
      Purchaser.  All of the terms, conditions, promises, covenants,
      provisions and warranties of this Agreement shall inure to the benefit of each
      of the undersigned, and shall bind the representatives, successors and permitted
      assigns of the Company.

      Agreement; Maximum Interest.  This Agreement, the Related
      Agreements, the exhibits and schedules hereto and thereto and the other
      documents delivered pursuant hereto constitute the full and entire understanding

      party shall be liable or bound to any other in any manner by any
      representations, warranties, covenants and agreements except as specifically
      set
      forth herein and therein.  Nothing contained in this Agreement, any
      Related Agreement or in any document referred to herein or delivered in
      connection herewith shall be deemed to establish or require the payment of
      a
      rate of interest or other charges in excess of the maximum rate permitted by
      applicable law.  In the event that the rate of interest or dividends
      required to be paid or other charges hereunder exceed the maximum rate permitted
      by such law, any payments in excess of such maximum shall be credited against
      amounts owed by the Company to the Purchaser and thus refunded to the
      Company.




28

      Agreement may be amended or modified only upon the written consent of the
      Company and the Purchaser.

      obligations of the Company and the rights of the Purchaser under this Agreement

      or
      noncompliance by another party under this Agreement or the Related Agreements,

      be a
      waiver of any such breach, default or noncompliance, or any acquiescence
      therein, or of or in any similar breach, default or noncompliance thereafter
      occurring.  All remedies, either under this Agreement or the Related
      Agreements, by law or otherwise afforded to any party, shall be cumulative
      and
      not alternative.
