      of
      any Person adverse to Lender (but only to the extent the claim of such Person

      and execute such financing statements and other documents as Lender may from
      time to time reasonably request in writing to maintain the perfected status
      of
      the Security Interest. Debtor shall not further encumber or grant a security
      interest in any of the Collateral except as provided for in the Loan
      Agreement.

          -

        
          

        

      

      
         

      

    

     

    (b) Debtor
      further agrees to take any other commercially reasonable action reasonably
      requested in writing by Lender if necessary to ensure the attachment, perfection
      and priority of, and the ability of Lender to enforce its security interest
      in
      any and all of the Collateral including, without limitation, (i) executing,
      delivering and, where appropriate, filing financing statements and amendments
      relating thereto under the UCC, to the extent, if any, that Debtor’s signature
      thereon is required therefor, (ii) complying with any provision of any
      statute, regulation or treaty of the United States as to any Collateral if
      compliance with such provision is a condition to attachment, perfection or
      priority of, or ability of Lender to enforce, its security interest in such
      Collateral, (iii) taking all actions required by any earlier versions of the
      UCC
      (to the extent applicable) or by other law, as applicable in any relevant UCC
      jurisdiction, or by other law as applicable in any foreign jurisdiction, (iv)
      obtaining waivers from landlords where any material portion of the tangible
      Collateral is located in form and substance reasonably satisfactory to Lender,
      and (v) executing such documents and cooperating with the Lender and any
      third-party to allow Lender to obtain control of any Collateral consisting
      of
      deposit accounts or investment property.

     

    3.3 Locations.
      Give
      Lender at least thirty (30) days prior written notice of Debtor’s intention to
      relocate any of the Collateral (other than Inventory in transit) or any of
      the
      records relating to the Collateral from the locations listed on Schedule
      1
      attached
      to this Security Agreement, in which event Schedule
      1
      shall be
      deemed amended to include the new location. Any additional filings or refilings
      requested in writing by Lender as a result of any such relocation in order
      to
      maintain the Security Interest in such Collateral shall be at Debtor’s
      expense.

     

    3.4 Insurance.
      Maintain insurance (including, without limitation, commercial general liability
      and property insurance) with respect to the Collateral consisting of tangible
      personal property in such amounts, against such risks, in such form and with
      responsible and reputable insurance companies or associations as is required
      by
      any governmental authority having jurisdiction with respect thereto or as is
      carried generally in accordance with sound business practice by companies in
      similar businesses similarly situated. If requested in writing by Lender, and
      if
      the existing third-party loss payee agrees to relinquish its position as loss
      payee, Debtor will obtain lender’s loss payable endorsements on applicable
      insurance policies in favor of Lender and will provide to Lender certificates
      of
      such insurance or copies thereof. If such request is made, and if the existing
      third-party loss payee agrees to relinquish its position as loss payee, Debtor
      shall use commercially reasonable efforts to cause each insurer to agree, by
      endorsement on the policy or policies or certificates of insurance issued by
      it
      or by independent instrument furnished to Lender, that such insurer will give
      thirty (30) days written notice to Lender before such policy will be altered
      or
      canceled. No settlement of any insurance claim shall be made without Lender’s
      prior consent, which consent will not be unreasonably withheld, conditioned
      or
      delayed. In the event of any insured loss, Debtor shall promptly notify Lender
      thereof in writing, and, after an Event of Default shall have occurred and
      be
      continuing, Debtor hereby authorizes and directs any insurer concerned to make
      payment of such loss directly to Lender as its interest may appear. Lender
      is
      authorized, in the name and on behalf of Debtor, to make proof of loss and
      to
      adjust, compromise and collect, in such manner and amounts as it reasonably
      shall determine, all claims under all policies; and Debtor agrees to sign,
      on
      written demand of Lender, all receipts, vouchers, releases and other instruments
      which may be necessary in aid of this authorization. After an Event of Default
      shall have occurred and be continuing, the proceeds of any insurance from loss,
      theft, or damage to the Collateral shall be held in a segregated account
      established by Lender and disbursed and applied at the discretion of Lender,
      either in reduction of the Obligations or applied toward the repair, restoration
      or replacement of the Collateral.

    3.5 Name;
      Legal Status.
      (a)
      Without providing at least 30 days prior written notice to Lender, Debtor will
      not change its name, its place of business or, if more than one, chief executive
      office, or its mailing address or organizational identification number if it
      has
      one, (b) if Debtor does not have an organizational identification number and
      later obtains one, Debtor shall forthwith notify Lender of such organizational
      identification number, and (c) Debtor will not change its type of organization
      or jurisdiction of organization.

     

    ARTICLE
      IV 

    RIGHTS
      AND REMEDIES

     

    4.1 Right
      to Cure.
      In case
      of failure by Debtor after receipt of written notice from Lender to procure
      or
      maintain insurance, or to pay any fees, assessments, charges or taxes (subject
      to Debtor’s right to contest in good faith, such assessments, charges or taxes)
      arising with respect to the Collateral, Lender shall have the right, but shall
      not be obligated, to effect such insurance or pay such fees, assessments,
      charges or taxes, as the case may be, and, in that event, the cost thereof
      shall
      be payable by Debtor to Lender immediately upon demand, together with interest
      at an annual rate of 8% from the date of disbursement by Lender to the date
      of
      payment by Debtor. If Lender effects any insurance on behalf of Debtor, Debtor
      thereafter may cancel such insurance so effected after providing Lender with
      evidence that Debtor or another secured party having cure rights similar to
      those set forth in this Section 4.1 has obtained insurance as required by this
      Security Agreement..

     

    4.2 Rights
      of Parties.
      Upon
      the occurrence and during the continuance of an Event of Default, in addition
      to
      all the rights and remedies provided in the Transaction Documents or in
      Article 9 of the UCC and any other applicable law, Lender may (but is under
      no obligation so to do):

     

    (a) require
      Debtor to assemble the Collateral at a place designated by Lender, which is
      reasonably convenient to the parties; and

     

    (b) take
      possession of all Collateral and of Debtor’s records pertaining to all
      Collateral that are necessary to properly administer and control the Collateral
      or the handling and collection of Collateral, and sell, lease or otherwise
      dispose of the Collateral in a commercially reasonable manner in whole or in
      part, at public or private sale, on or off the premises of Debtor;
      and

     

    (c) collect
      any and all money due or to become due and enforce in Debtor’s name all rights
      with respect to the Collateral; and

     

    (d) settle,
      adjust or compromise any dispute with respect to any Account; and

     

    (e)  receive
      and open mail addressed to Debtor; and

     

    (f)  on
      behalf of Debtor, endorse checks, notes, drafts, money orders, instruments
      or
      other evidences of payment.

     

    4.3 Power
      of Attorney.
      Upon
      the occurrence and during the continuance of an Event of Default, Debtor does
      hereby constitute and appoint Lender as Debtor’s true and lawful attorney with
      full power of substitution for Debtor in Debtor’s name, place and stead for the
      purposes of performing any obligation of Debtor under this Security Agreement
      and taking any action and executing any instrument which Lender may deem
      necessary to perform any obligation of Debtor under this Security Agreement,
      which appointment is irrevocable and coupled with an interest, and shall not
      terminate until the Obligations are paid in full.

    4.4 Right
      to Collect Accounts.
      Upon
      the occurrence and during the continuance of an Event of Default, and without
      limiting Debtor’s obligations under the Transaction Documents: (a) Debtor
      authorizes Lender to notify any and all debtors on the Accounts to make payment
      directly to Lender (or to such place as Lender may direct); (b) Debtor agrees,
      on written notice from Lender, to deliver to Lender promptly after receipt
      thereof, in the form in which received (together with all necessary
      endorsements), all payments received by Debtor on account of any Account; and
      (c) Lender may, at its option, apply all such payments against the Obligations
      or remit all or part of such payments to Debtor.

     

    4.5 Reasonable
      Notice.
      Written
      notice, when required by law, sent in accordance with the provisions of Section
      12.6 of the Loan Agreement and given at least ten (10) business days (counting
      the day of sending) before the date of a proposed disposition of the Collateral
      shall be reasonable notice.

     

    4.6 Limitation
      on Duties Regarding Collateral.  The
      sole duty of Lender with respect to the custody, safekeeping and physical
      preservation of the Collateral in its possession, under Section 9-207 of the
      UCC
      or otherwise, shall be to deal with it in the same manner as Lender deals with
      similar property for its own account. Neither Lender nor any of its directors,
      officers, employees or agents, shall be liable for failure to demand, collect
      or
      realize upon any of the Collateral or for any delay in doing so or shall be
      under any obligation to sell or otherwise dispose of any Collateral upon the
      request of Debtor or otherwise.

     

    4.7 Lock
      Box; Collateral Account.
      This
      Section 4.7 shall be effective only upon the occurrence and during the
      continuance of an Event of Default. If Lender so requests in writing, Debtor
      will direct each of its debtors on the Accounts to make payments due under
      the
      relevant Account or chattel paper directly to a special lock box to be under
      the
      control of Lender. Debtor hereby authorizes and directs Lender to deposit into
      a
      special collateral account to be established and maintained by Lender all
      checks, drafts and cash payments received in said lock box. All deposits in
      said
      collateral account shall constitute proceeds of Collateral and shall not
      constitute payment of any Obligation until so applied. At its option, Lender
      may, at any time, apply finally collected funds on deposit in said collateral
      account to the payment of the Obligations, in the order of application set
      forth
      in Section 4.8, or permit Debtor to withdraw all or any part of the balance
      on
      deposit in said collateral account. If a collateral account is so established,
      Debtor agrees that it will promptly deliver to Lender, for deposit into said
      collateral account, all payments on Accounts and chattel paper received by
      it.
      All such payments shall be delivered to Lender in the form received (except
      for
      Debtor’s endorsement where necessary). Until so deposited, all payments on
      Accounts and chattel paper received by Debtor shall be held in trust by Debtor
      for and as the property of Lender and shall not be commingled with any funds
      or
      property of Debtor.

     

    4.8 Application
      of Proceeds.
      Lender
      shall apply the proceeds resulting from any sale or disposition of the
      Collateral in the following order:

     

    (a) to
      the
      reasonable costs of any sale or other disposition;

     

    (b) to
      the
      reasonable expenses incurred by Lender in connection with any sale or other
      disposition, including attorneys’ fees;

     

    (c) to
      the
      payment of the Obligations then due and owing in any order selected by Lender
      in
      a commercially reasonable manner; and

     

    (d) to
      Debtor.

     

    4.9 Other
      Remedies.
      No
      remedy herein conferred upon Lender is intended to be exclusive of any other
      remedy, and each and every such remedy shall be cumulative and shall be in
      addition to every other remedy given under this Security Agreement and the
      Transaction Documents now or hereafter existing at law or in equity or by
      statute or otherwise. No failure or delay on the part of Lender in exercising
      any right or remedy hereunder shall operate as a waiver thereof nor shall any
      single or partial exercise of any right hereunder preclude other or further
      exercise thereof or the exercise of any other right or remedy.

      such prohibition or unenforceability without invalidating the remaining
      provisions of this Security Agreement in such jurisdiction or affecting the
      validity or enforceability of any provision in any other
      jurisdiction.

    2. BUYER
      REPRESENTATIONS AND WARRANTIES.

     

    Each
      Buyer, individually and not jointly and severally, represents and warrants,
      as
      of the date of this Agreement and the Closing Date, with respect to only itself,
      that:

     

    a. Investment
      Purpose.
      Such
      Buyer (i) is acquiring the Sub Notes (along with the related Guarantees) and
      the
      Warrant acquired by such Buyer hereunder, (ii) upon any exercise of the Warrant,
      will acquire the Warrant Shares issuable upon such exercise thereof, and (iii)
      upon any exercise of the Investor Share Option (as defined in each of the Sub
      Notes), will acquire the shares of Common Stock issuable upon such exercise
      thereof (the “Option
      Shares”
and,
      collectively with the Sub Notes, the Guarantees, the Warrant and the Warrant
      Shares, the “Securities”)
      for
      its own account and not with a view towards, or for resale in connection with,
      the public sale or distribution thereof, except pursuant to sales registered
      under, or exempted from the registration requirements of, the 1933 Act;
provided,
      however, that by making the representations herein, such Buyer does not agree
      to
      hold any of the Securities acquired by it for any minimum or other specific
      term
      and reserves the right to dispose of the Securities at any time in accordance
      with or pursuant to an effective registration statement or an exemption from
      registration under the 1933 Act.

    
      
         

      

      
        3

        
          

        

      

      
         

      

    

    b. Accredited
      Investor Status.
      Such
      Buyer is an “accredited investor” as that term is defined in Rule 501(a) of
      Regulation D.

     

    c. Reliance
      on Exemptions.
      Such
      Buyer understands that the Securities are being offered and sold to it in
      reliance on specific exemptions from the registration requirements of the
      securities laws and that the Company is relying in part upon the truth and
      accuracy of, and such Buyer’s compliance with, the representations, warranties,
      agreements, acknowledgments and understandings of such Buyer set forth herein
      in
      order to determine the availability of such exemptions and the eligibility
      of
      such Buyer to acquire the Securities. For purposes hereof, “securities
      laws”
means
      the securities laws, legislation and regulations of, and the instruments,
      policies, rules, orders, codes, notices and interpretation notes of, the
      securities regulatory authorities (including the SEC) of the United States
      and
      any applicable states and other jurisdictions. 

     

    d. Information.
      Such
      Buyer and its advisors, if any, have been furnished with all materials relating
      to the business, finances and operations of the Company and the Subsidiaries
      and
      materials relating to the offer and sale of the Securities that have been
      requested by such Buyer. Such Buyer and its advisors, if any, have been afforded
      the opportunity to ask questions of the Company. Neither such inquiries nor
      any
      other due diligence investigations conducted by such Buyer or its advisors,
      if
      any, or its representatives shall modify, amend or affect such Buyer’s right to
      rely on the Company’s representations and warranties contained in Section
      3
      below or
      contained in any of the other Transaction Documents. Such Buyer understands
      that
      its investment in the Securities involves a high degree of risk. Such Buyer
      has

      to
      make an informed investment decision with respect to its acquisition of the
      Securities. 

     

    e. No
      Governmental Review.
      Such
      Buyer understands that no Governmental Entity has passed on or made any
      recommendation or endorsement of the Securities or the fairness or suitability
      of an investment in the Securities nor have such authorities passed upon or
      endorsed the merits of the offering of the Securities. As used in this
      Agreement, “Governmental
      Entity”
means
      the government of the United States or any other nation, or any political
      subdivision thereof, whether state, provincial or local, or any agency
      (including any self-regulatory agency or organization), authority,
      instrumentality, regulatory body, court, central bank or other entity exercising
      executive, legislative, judicial, taxing, regulatory or administration powers
      or
      functions of or pertaining to government over the Company or any of the
      Subsidiaries, or any of their respective properties, assets or
      undertakings.

    f. Transfer
      or Resale.
      Such
      Buyer understands that: (i) the Securities have not been and are not being
      registered under the 1933 Act or any other securities laws, and may not be
      offered for sale, sold, assigned or transferred unless (A) subsequently
      registered thereunder, (B) such Buyer shall have delivered to the Company an
      opinion of counsel, in a generally acceptable form, to the effect that such
      Securities to be sold, assigned or transferred may be sold, assigned or
      transferred pursuant to an exemption from such registration, or (C) such
      Buyer provides the Company with reasonable assurance that such Securities can
      be
      sold, assigned or transferred pursuant to Rule 144 promulgated under the
      1933 Act, as amended (or a successor rule thereto) (“Rule
      144”);
      (ii) any sale of the Securities made in reliance on Rule 144 may be made
      only in accordance with the terms of Rule 144, and further, if Rule 144 is
      not
      applicable, any resale of the Securities under circumstances in which the seller
      (or the Person through whom the sale is made) may be deemed to be an underwriter
      (as that term is defined in the 1933 Act) may require compliance with some
      other
      exemption under the 1933 Act or any other securities laws; and
      (iii) neither the Company nor any other Person is under any obligation to
      register the Securities under the 1933 Act or any other securities laws.
      Notwithstanding the foregoing, the Securities may be pledged in connection
      with
      a bona fide margin account or other loan or financing arrangement secured by
      the
      Securities. As used in this Agreement, “Person”
means
      an individual, a limited liability company, a partnership, a joint venture,
      a
      corporation, a trust, an unincorporated organization or a Governmental Entity
      or
      any other legal entity.

     

    g. Legends.
      Such
      Buyer understands that the certificates or other instruments representing the
      Securities, except as set forth below, shall bear a restrictive legend in the
      following form (the “1933
      Act Legend”)
      (and a
      stop-transfer order may be placed against transfer of such
      certificates):

     

    THE
      SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE
      SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE SECURITIES LAWS. THE
      SECURITIES MAY NOT BE OFFERED FOR SALE, SOLD, TRANSFERRED OR ASSIGNED (I) IN
      THE
      ABSENCE OF (A) AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER
      THE
      SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE SECURITIES LAWS OR
      (B)
      AN OPINION OF COUNSEL, IN A GENERALLY ACCEPTABLE FORM, THAT REGISTRATION IS
      NOT
      REQUIRED UNDER SAID ACT OR APPLICABLE STATE SECURITIES LAWS OR (II) UNLESS
      SOLD
      PURSUANT TO RULE 144 UNDER SAID ACT. NOTWITHSTANDING THE FOREGOING, THE
      SECURITIES MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT OR
      OTHER
      LOAN OR FINANCING ARRANGEMENT SECURED BY THE SECURITIES.

    Upon
      the
      written request to the Company of a holder of a certificate or other instrument
      representing any Securities, the 1933 Act Legend shall be removed and the
      Company shall issue a certificate without the 1933 Act Legend to the holder
      of
      the Securities upon which it is stamped, if (i) such Securities are registered
      for resale under the 1933 Act, (ii) in connection with a sale transaction,
      such
      holder provides the Company with an opinion of counsel, in a generally
      acceptable form, to the effect that a public sale, assignment or transfer of
      the
      Securities may be made without registration under the 1933 Act, (iii) such
      holder provides the Company with reasonable assurances that the Securities
      can
      be sold pursuant to Rule 144 without compliance with Rule 144(e) or Rule 144(f)
      (or successors thereto), (iv) such holder provides the Company reasonable
      assurances that the Securities have been or are being sold pursuant to Rule
      144,
      or (v) such holder certifies, on or after the date that is six (6) months after
      the date on which such holder acquired the Securities (or is deemed to have
      acquired the Securities under Rule 144), that such holder is not an “affiliate”
of the Company (as defined in Rule 144). Any Option Shares issued pursuant
      to
      the Investor Share Option on or after the date that is six (6) months after
      the
      Closing Date to any Buyer that certifies that such Buyer is not an affiliate
      of
      the Company, as defined in Rule 144, shall be issued without the 1933 Act
      Legend. The Company shall be responsible for the fees of its transfer agent
      and
      all of The Depository Trust Company (the “DTC”)
      fees
      associated with such issuance. The Company acknowledges that a breach by it
      of
      its obligations hereunder will cause irreparable harm to the holders of the
      Securities. Accordingly, the Company acknowledges that the remedy at law for
      a
      breach of its obligations under this Section
      3(g)
      will be
      inadequate and agrees that, in the event of a breach or threatened breach of
      this Section
      3(g),
      such
      holder shall be entitled, in addition to all other available remedies, to an
      injunctive order and/or injunction restraining any breach and requiring
      immediate issuance and transfer, without the necessity of showing economic
      loss
      and without any bond or other security being required.

      Enforcement; Validity.
      Such
      Buyer is a validly existing limited partnership and has the requisite limited
      partnership power and authority to purchase the Securities pursuant to this
      Agreement. This Agreement has been duly and validly authorized, executed and
      delivered on behalf of such Buyer and is the valid and binding agreement of

      to Units.
      Such
      Buyer immediately prior to Closing will have good and marketable title to each
      of the Exchanged Securities owned by it, free and clear of any Liens. There
      are
      no preemptive, conversion, subscription or other rights, options, warrants
      or
      agreements granted or issued by, or binding upon, such Buyer for the purchase
      or
      acquisition of any of the Exchanged Securities. Upon delivery to the Company
      by
      such Buyer of the Exchanged Securities owned by it, good and marketable title
      to
      such Exchanged Securities (in the case of the Old Warrant, only with respect

      conveyed, transferred and delivered to the Company, free and clear of all Liens.
      

     

    k. No
      Conflict.
      Neither
      the execution and delivery of this Agreement or any Transaction Document by
      such
      Buyer nor the performance by such Buyer of the transactions contemplated hereby
      or thereby will, directly or indirectly, contravene, conflict with, or result
      in
      (with or without notice or lapse of time) a violation or breach of any of the
      Exchanged Securities owned by it, or give any Person the right (with or without
      notice or lapse of time) to declare a default or exercise any remedy under,
      or
      to accelerate the maturity or performance of, or to cancel, terminate, modify,
      withdraw or suspend any of the Exchanged Securities owned by
      it.

    a. Organization

      is
      duly qualified to do business and is in good standing in every jurisdiction
      in
      which its ownership of property or the nature of the business conducted makes
      such qualification necessary, except to the extent that the failure to be so
      qualified or be in good standing could not have and could not be, individually
      or in the aggregate, reasonably be expected to have a Material Adverse Effect.
      Except as set forth on Schedule
      3(a),

      free

      Adverse Effect”
means
      any material adverse effect on (i) the business, properties, assets, operations,
      results of operations, condition (financial or otherwise), credit worthiness
      or
      prospects of the Company and the Subsidiaries, taken as a whole, (ii) the
      transactions contemplated hereby or the agreements and instruments to be entered
      into in connection herewith, or (iii) the authority or ability of the Company
      or

      Stock, equity or similar interests of each of the Subsidiaries, in each case,
      free and clear of any Liens (as defined below), including
      any restriction on the use, voting, transfer, receipt of income or other
      exercise of any attributes of free and clear ownership by a current holder
      (other than restrictions arising under federal or state securities laws), and
      no
      such Subsidiary owns
      Capital Stock or holds an equity or similar interest in any other Person. As
      used in this Agreement, “Lien”
means
      with respect to any asset, any mortgage, lien, pledge, hypothecation, charge,
      security interest, encumbrance or adverse claim of any kind and any
      restrictive covenant, condition, restriction or exception of any kind that
      has
      the practical effect of creating a mortgage, lien, pledge, hypothecation,
      charge, security interest, encumbrance or adverse claim of any kind
      (including any of the foregoing created by, arising under or evidenced by any
      conditional sale or other title retention agreement, the interest of a lessor
      with respect to a Capital Lease Obligation, or any financing lease having
      substantially the same economic effect as any of the foregoing); “Subsidiary”

      or
      holds an equity or similar interest (at the time of this Agreement or at any

      and
      the amount of such obligation shall be the capitalized amount thereof,
      determined in accordance with GAAP; and “Capital
      Stock”
means

      designated) of capital stock of a corporation, any and all equivalent ownership
      interests in a Person (other than a corporation) and any and all warrants,
      rights or options to purchase any of the foregoing

      The
      Company and each of the Subsidiaries have the requisite corporate power and
      authority to enter into and perform their obligations under each of the
      Transaction Documents, and solely with respect to the Company, to issue the
      Securities in accordance with the terms hereof and thereof. The execution and

      the
      respective boards of directors, members, managers, stockholders or other
      equityholders, as applicable, of the Company and each of the Subsidiaries and

      further consent or authorization is required by the Company, any of the

      stockholders or other equityholders, as applicable. This Agreement and the
      other
      Transaction Documents dated of even date herewith to which the Company or any
      Subsidiary is a party have been duly executed and delivered by the Company
      and
      such Subsidiary, and constitute the valid and binding obligations of the Company
      and each such Subsidiary, enforceable against the Company and each such
      Subsidiary in accordance with their respective terms, except as may be limited
      by bankruptcy, insolvency, fraudulent conveyance or similar laws affecting

      the Transaction Documents dated after the date of this Agreement and on or
      prior
      to the Closing Date shall have been duly executed and delivered by the Company
      and each Subsidiary party thereto and shall constitute the valid and binding

      (i)
      result in a violation of the charter, certificate or articles of incorporation,
      certificate or articles of organization, bylaws, operating agreement,

      or would constitute a breach or default) under, or give to others any right
      of
      termination, amendment, acceleration or cancellation of, or other remedy with

      business of the Company and the Subsidiaries has not been and is not being

      statements and other documents required to be filed by it with the SEC pursuant
      to the reporting requirements of the 1934 Act (all of the foregoing filed since
      December 31, 2005 and prior to the date this representation is made (including
      all exhibits included therein and financial statements and schedules thereto
      and
      documents incorporated by reference therein) being referred to herein as the
      “SEC
      Documents”

      Company’s consolidated balance sheet as of June 30, 2008, as included in the
      Company’s quarterly report on Form 10-Q for the period then ended, as filed with
      the SEC on August 15, 2008, being referred to herein as the “Latest
      Balance Sheet”).
      A
      complete and accurate list of the SEC Documents is set forth on Schedule
      3(f).
      The
      Company has made available to each Buyer or its respective representatives
      true
      and complete copies of the SEC Documents. Each of the SEC Documents was filed
      with the SEC within the time frames prescribed by the SEC for filing of such
      SEC
      Documents (including any extensions of such time frames permitted by Rule 12b-25
      under the 1934 Act pursuant to timely filed Forms 12b-25) such that each filing
      was timely filed (or deemed timely filed pursuant to Rule 12b-25 under the
      1934
      Act) with the SEC. As of their respective dates, the SEC Documents complied
      in
      all material respects with the securities laws. Except as set forth on
Schedule
      3(f),
      none of
      the SEC Documents, at the time they were filed with the SEC, contained any
      untrue statement of a material fact or omitted to state a material fact required
      to be stated therein or necessary in order to make the statements therein,
      in
      light of the circumstances under which they were made, not misleading. Except
      as
      set forth on Schedule
      3(f),
      since
      the filing of each of the SEC Documents, no event has occurred that would
      require an amendment or supplement to any such SEC Document and as to which
      such
      an amendment has not been filed and made publicly available on the SEC’s EDGAR
      system no less than five (5) Business Days prior to the date the representation
      is made. The Company has not received any written comments from the SEC staff
      that have not been resolved to the satisfaction of the SEC staff. As of their
      respective dates, the consolidated financial statements of the Company and
      the
      Subsidiaries included in the SEC Documents (including the notes thereto, the
      “Financial
      Information”)
      complied as to form in all material respects with applicable accounting
      requirements and the securities laws with respect thereto. Such consolidated
      financial statements have been prepared in accordance with GAAP, consistently
      applied, during the periods involved (except (i) as may be otherwise indicated
      in such financial statements or the notes thereto, or (ii) in the case of
      unaudited interim statements, to the extent they may exclude footnotes or may
      be
      condensed or summary statements) and fairly present in all material respects
      the
      financial position of the Company and the Subsidiaries as of the dates thereof
      and the results of their operations and cash flows for the periods then ended
      (subject, in the case of unaudited statements, to normal year-end audit
      adjustments that are not material individually or in the aggregate). As of
      the
      date hereof and as of the Closing Date, the Financial Information is true,
      accurate and complete, has been prepared in accordance with GAAP, is consistent
      with the books and records of the Company and its predecessors (which are true,
      accurate and complete), and fairly presents such information as of the dates,
      and for the periods, presented. Since the date of the Latest Balance Sheet,
      there has been no change in the Company’s reserve or accrual amounts or
      policies. Schedule
      3(f)
      lists
      all press releases, analyst reports, advertisements and other written
      communications with stockholders or other investors, or potential stockholders
      or other potential investors, on behalf of the Company or any of the
      Subsidiaries or otherwise relating to the Company or any of the Subsidiaries,
      issued, made, distributed, paid for or approved since December 31, 2005 by
      the
      Company, any of the Subsidiaries or any of their respective officers, directors
      or Affiliates (as defined in Section
      3(k)),
      by any
      Person engaged by (or otherwise acting on behalf of) the Company, any of the
      Subsidiaries or any of their respective officers, directors or Affiliates,
      or,
      to the Company’s Knowledge, by any stockholder of the Company. None of the
      Company, the Subsidiaries and their respective officers, directors and
      Affiliates or, to the Company’s Knowledge, any stockholder of the Company has
      made any filing with the SEC, issued any press release or made, distributed,
      paid for or approved (or engaged any other Person to make or distribute) any
      other public statement, report, advertisement or communication on behalf of
      the
      Company or any of the Subsidiaries or otherwise relating to the Company or
      any
      of the Subsidiaries that contains any untrue statement of a material fact or
      omits any statement of material fact necessary in order to make the statements
      therein, in the light of the circumstances under which they are or were made,
      not misleading or has provided any other information to any Buyer, including
      information referred to in Section
      2(d),
      that,
      considered in the aggregate, contains any untrue statement of a material fact
      or
      omits to state any material fact necessary in order to make the statements
      therein, in the light of the circumstances under which they are or were made,
      not misleading. Except as set forth on Schedule
      3(f),
      none of
      the Company, the Subsidiaries and their respective officers, directors,
      employees or agents has provided any Buyer with any material, non-public
      information. The Company is not required to file and will not be required to
      file any agreement, note, lease, mortgage, deed or other instrument entered
      into
      prior to the date this representation is made and in effect on the date this
      representation is made and to which the Company or any Subsidiary is a party
      or
      by which the Company or any Subsidiary is bound that has not been previously
      filed as an exhibit (including by way of incorporation by reference) to the
      Company’s reports filed or made with the SEC under the 1934 Act. The accounting
      firm that has expressed its opinion with respect to the consolidated financial
      statements included in the Company’s most recently filed annual report on Form
      10-K or 10-KSB (the “Audit
      Opinion”)
      is
      independent of the Company pursuant to the standards set forth in Rule 2-01
      of
      Regulation S-X promulgated by the SEC and such firm was otherwise qualified
      to
      render the Audit Opinion under applicable securities laws. Each other accounting
      firm that since such filing has conducted or will conduct a review or audit
      of
      any of the Company’s consolidated financial statements is independent of the
      Company pursuant to the standards set forth in Rule 2-01 of Regulation S-X
      promulgated by the SEC and is otherwise qualified to conduct such review or
      audit and render an audit opinion under applicable securities laws. There is
      no
      transaction, arrangement or other relationship between the Company and an
      unconsolidated or other off-balance-sheet entity that is required to be
      disclosed by the Company in its reports pursuant to the 1934 Act that has not
      been so disclosed in the SEC Documents. Since December 31, 2003, except as
      set
      forth on Schedule
      3(f),
      neither
      the Company nor any of the Subsidiaries nor any director, officer or employee,
      of the Company or any of the Subsidiaries has received or otherwise had or
      obtained Knowledge of any material complaint, allegation, assertion or claim,
      whether written or oral, regarding the accounting or auditing practices,
      procedures, methodologies or methods of the Company or any of the Subsidiaries
      or its internal accounting controls, including any complaint, allegation,
      assertion or claim that the Company or any of the Subsidiaries has engaged
      in
      questionable accounting or auditing practices. No attorney representing the
      Company or any of the Subsidiaries, whether or not employed by the Company
      or
      any of the Subsidiaries, has reported evidence of a material violation of
      securities laws, breach of fiduciary duty or similar violation by the Company
      or
      any of the Subsidiaries or any of their respective officers, directors,
      employees or agents to their respective boards of directors or any committee
      thereof or pursuant to Section 307 of the Sarbanes-Oxley Act of 2002, and the
      SEC’s rules and regulations promulgated thereunder. Since December 31, 2001,
      there have been no internal or SEC investigations regarding accounting or
      revenue recognition discussed with, reviewed by or initiated at the direction
      of
      any executive officer, board of directors or any committee thereof of the
      Company or any of the Subsidiaries. As of the date of this Agreement, the
      Company is not, and at no time since February 14, 2008 has been, a “shell
      company” (as defined in Rule 12b-2 under the Exchange Act).

    g. Absence
      of Certain Changes.
      Neither
      the Company nor any of the Subsidiaries has taken any steps, and neither the
      Company nor any such Subsidiary expects to take any steps to seek protection
      pursuant to any bankruptcy law, and neither the Company nor any Subsidiary
      has
      received any written notice or has any other knowledge or reason to believe
      that
      the creditors of such Person intend to initiate involuntary bankruptcy
      proceedings against the Company or any of the Subsidiaries or any knowledge

      debts mature or (iv) such Person has unreasonably small capital with which
      to conduct the business in which it is engaged as such business is now conducted

    j. Acknowledgment
      Regarding Buyers’ Purchase of Securities.
      The
      Company acknowledges and agrees that each Buyer is acting solely in the capacity
      of an arm’s length purchaser with respect to the Company in connection with this
      Agreement and the other Transaction Documents and the transactions contemplated
      hereby and thereby. The Company further acknowledges that each Buyer is not
      acting as a financial advisor or fiduciary of any party to this Agreement or

      of the other Transaction Documents (or in any similar capacity) with respect
      to
      this Agreement and the other Transaction Documents and the transactions
      contemplated hereby and thereby, and any advice given by any Buyer or any of
      its
      representatives or agents in connection with the Transaction Documents and

      neither
      the Company nor any of its Affiliates, nor any Person acting on the behalf
      of
      any of the foregoing, has engaged or will engage in any form of general
      solicitation or general advertising (within the meaning of Regulation D
      under the 1933 Act), including advertisements, articles, notices, or other
      communications published
      in any
      newspaper, magazine or similar media or broadcast over radio, television or
      internet or any seminar meeting whose attendees have been invited by general
      solicitation or general advertising, in connection with the offer or sale of
      the
      Securities. As used in this Agreement, “Affiliate”
means,
      with respect to any Person, a second Person (A) in which the first Person owns
      a
      five percent (5%) equity interest, or (B) that, directly or indirectly,
      (i) has a five percent (5%) equity interest in such first Person, (ii) has
      a common ownership with such first Person, (iii) controls such first

      purposes of this Section
      3(k).

     

    l. No
      Integrated Offering.
      Neither
      the Company nor any Subsidiaries, Affiliates of the foregoing or any Person
      acting on the behalf of any of the foregoing, has, directly or indirectly,
      made
      any offers or sales of any security or solicited any offers to purchase any
      security, under circumstances that would require registration of any of the
      Securities under the 1933 Act or cause this offering of the Securities to be
      integrated with prior offerings by the Company for purposes of the 1933 Act
      or
      any applicable stockholder approval requirements of any authority, nor will
      the
      Company, any Subsidiaries, any Affiliates of the foregoing, or any Person acting
      on behalf of any of the foregoing, take any action or steps that would require
      registration of the issuance of any of the Securities under the 1933 Act or
      cause the offering of the Securities to be integrated with other offerings
      for
      purposes of the 1933 Act or any applicable stockholder approval requirements

    m. Dilutive
      Effect.

      Company understands and acknowledges that the number of Warrant Shares that
      the
Company
      is
      obligated to issue upon exercise of the Warrant will increase in certain
      circumstances. The Company further acknowledges that its obligation to issue
      the
      Warrant Shares upon exercise of the Warrant is absolute and unconditional
      regardless of the dilutive effect that such issuance may have on the ownership
      interests of other stockholders of the Company. Taking the foregoing into
      account, the Company’s board of directors has determined in its good faith
      business judgment that the issuance of the Warrant and the consummation of
      the
      other transactions contemplated hereby and by the other Transaction Documents
      are in the best interests of the Company and its stockholders.

      a
      member of a union that relates to such employee’s relationship with the Company
      or of any of the Subsidiaries. Neither the Company nor any of the Subsidiaries

      or any of the Subsidiaries that such individual intends to leave the Company
      or
      any of the Subsidiaries or otherwise terminate such individual’s employment or
      relationship with the Company or any of the Subsidiaries. No such individual,
      to
      the Company’s Knowledge, is, has been, or is expected to be, in violation of any
      material term of any employment contract, confidentiality, disclosure or
      proprietary information agreement or non-competition agreement, or any other
      contract or agreement or any restrictive covenant, and the continued employment
      of each such individual does not, has not and will not subject the Company
      or
      any of the Subsidiaries to any liability with respect to any of the foregoing
      matters. Except as set forth on Schedule
      3(n),
      the
      Company and each of the Subsidiaries is and has been in compliance with all
      Laws
      relating to employment and employment practices, terms and conditions of

    r. Insurance.
      The
      Company and each of the Subsidiaries are insured by insurers of recognized
      financial responsibility against such losses and risks and in such amounts
      as
      management of the Company believes to be prudent and customary in the businesses
      in which the Company and the Subsidiaries are engaged. Neither the Company
      nor
      any Subsidiary has been refused any insurance coverage sought or applied for,
      and neither the Company nor any Subsidiary 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 as may
      be
      necessary to continue its business at a cost that would not reasonably be
      expected to have a Material Adverse Effect.

     

    s. Regulatory
      Permits.

      certificates, authorizations, approvals, licenses and permits issued by the
      appropriate federal, state or foreign regulatory authorities necessary to
      conduct their respective businesses

      the
      Company and the Subsidiaries possess all Permits necessary to produce, extract,
      transport and sell the oil, gas and other minerals in that portion of Real
      Property that is producing oil, gas, minerals and/or other hydrocarbons at
      the
      time this representation is made. Except as set forth on Schedule
      3(s)
      or as
      could not reasonably be expected to have a Material Adverse Effect, the Company
      and the Subsidiaries do not have any reason to believe that they will not be
      able to obtain necessary Permits as and when necessary to enable the Company
      to
      produce, extract, transport and sell the oil, gas, minerals and other
      hydrocarbons in any Real Property. Except as set forth on Schedule
      3(s),
      the
      Company is not in violation of any of the rules, regulations or requirements
      of

      however,
      that, if after the date of this Agreement the Common Stock is listed on a
      national securities exchange, the “Principal
      Market”
shall
      mean such national securities exchange) and the Company has no Knowledge of
      any
      facts or circumstances which would reasonably lead to delisting or suspension,
      or termination of the trading of, the Common Stock by or on the Principal Market
      in the foreseeable future. Except as set forth on Schedule
      3(s),
      since

      to
      ensure that the information required to be disclosed by the Company in the
      reports that it files with or submits to the SEC (X) is recorded,
      processed, summarized and reported accurately within the time periods specified
      in the SEC’s rules and forms and (Y) is accumulated and communicated to the
      Company’s management, including its principal executive officer and principal
      financial officer, as appropriate to allow timely decisions regarding required
      disclosure. Except as set forth on Schedule
      3(t),
      the
      Company maintains internal control over financial reporting required by
      Rule 13a-14 or Rule 15d-14 under the 1934 Act; such internal
      control over financial reporting is, and has at all times been, effective and
      does not contain, and has not contained, any material weaknesses.

      (the
“Real
      Property Leases”).
      Except as set forth on Schedule

      Company or one of the Subsidiaries is the legal and equitable owner of a
      leasehold interest in all of the Real Property, and possesses good, marketable

      the
      ability of the Company or the Subsidiaries to realize the benefits of the rights
      provided to any of them under the Real Property Leases. Except as set forth
      on
Schedule

      Real
      Property Leases and no event has occurred which with the giving of notice or
      the
      passage of time or both could constitute a default under, or otherwise give
      any
      party the right to terminate, any of such Real Property Leases, or could
      adversely affect the Company’s or any of the Subsidiaries’ interest in and title
      to the Real Property subject to any of such Real Property Leases. No Real
      Property Lease is subject to termination, modification or acceleration as a
      result of the transactions contemplated hereby or by the other Transaction
      Agreements. Except as set forth on Schedule
      3(bb),
      all of
      the Real Property Leases will remain in full force and effect upon, and permit,
      the consummation of the transactions contemplated hereby (including the granting
      of leasehold mortgages). The Real Property is permitted for its present uses
      under applicable zoning laws, is permitted conforming structures and complies
      with all applicable building codes, ordinances and other similar Laws. Except

      there
      are no pending or threatened requests, applications or proceedings to alter

      locations within the boundaries of the appropriate Real Property Lease; and
      no
      such well is subject to penalties on allowables after the date hereof because
      of
      any overproduction or violation of applicable laws, rules, regulations, permits
      or judgments, orders or decrees of any court or governmental body or agency
      which would prevent such well from being entitled to its full legal and regular
      allowance from and after the date hereof as prescribed by any court or
      Governmental Entity. Except as set forth on Schedule
      3(bb),
      there

      under
      a production sales contract containing a “take or pay” or similar provision,
      production payment, buydowns, buyouts, or any other arrangement, (i) to deliver
      hydrocarbons, or proceeds from the sale thereof, attributable to any of the
      Real
      Property at some future time without then or thereafter receiving the full
      contract price therefore, or (ii) to deliver oil or gas (or cash in lieu
      thereof) from the Real Property to other owners of interests as a result of

      production from the portion of the Real Property. To the Company’s Knowledge,
      the Real Property Leases will by their terms remain in effect for at least
      as

      are
      otherwise maintained by operations. For purposes of this Agreement,

      successor thereto)), or on any day hereafter sales of all of the Securities
      cannot be made as a result of a breach or violation of this Section
      4(c),
      then,
      as partial relief for the damages to any holder of Securities by reason of
      any
      reduction of its ability to sell the Securities (which remedy shall not be
      exclusive of any other remedies available hereunder, at law or in equity),

      of
      the Warrant or any Investor Shares Option held by) such holder with respect
      to
      each thirty (30) day period occurring on and after such failure, breach or
      violation and prior to the date that the applicable annual or quarterly report
      is filed with the SEC or the breach or violation is cured, as applicable (in
      each case, pro rated for periods totaling less than thirty (30) days). The

Filing
      Delay Payments shall be paid on the earlier of (I) the last day of the calendar

      Business Day after the failure, breach or violation giving rise to the Filing
      Delay Payments is cured. Notwithstanding the foregoing, no Filing Delay Payments
      shall accrue with respect to any period after the later of (A) the one-year
      anniversary of the date hereof, and (B) the first date after the Override
      Exchange Date (or, if the Company fails to deliver an Override Exchange Notice
      by the two-year anniversary of the Closing Date, the first date after such
      two-year anniversary) as of which the holders of Securities may sell all of
      the
      Securities pursuant to Rule 144 without the requirement for compliance with
      Rule
      144(c) (or successor thereto). In the event the Company fails to make Filing
      Delay Payments in a timely manner, such Filing Delay Payments shall bear
      interest, in each case until paid in full, at the rate of one and one-half
      percent (1.5%) per month, prorated for partial months. For purposes hereof,

      (without regard to any limitation thereon) of the Warrant or the Investor Share
      Option, on each of the five (5) Trading Days immediately preceding the date
      of
      the failure, breach or violation initially giving rise to the Filing Delay
      Payments; (ii) “Aggregate
      Market Value”
of
      the
      Warrant Shares and the Option Shares held by any holder thereof means the sum

      the respective Market Values of all of the Warrant Shares and the Option Shares

      that
      such Buyer shall be consulted by the Company in connection with any such press
      release or other public disclosure prior to its release and shall be provided
      with a copy thereof upon request).

    (iii) The
      Company represents, warrants and covenants to each Buyer that, from and after
      the filing of the Announcing Form 8-K with the SEC (subject to Section
      4(n)),
      such
      Buyer shall not be in possession of any material non-public information received
      from the Company, any of the Subsidiaries or any of their respective officers,
      directors, employees or agents. Notwithstanding any provision herein to the
      contrary, the Company shall not, and shall cause each of the Subsidiaries and
      its and each of their respective officers, directors, employees and agents
      not
      to, provide any Buyer or Investor (as defined in Section
      4(k))
      with
      any material non-public information regarding the Company or any of the
      Subsidiaries from and after the filing of the Announcing Form 8-K with the
      SEC,
      without the express prior written consent of such Buyer or Investor. In the
      event of a breach of the foregoing covenant by the Company, any of the
      Subsidiaries, or any of its or their respective officers, directors, employees
      and agents, in addition to any other remedy provided herein or in the
      Transaction Documents, such Buyer or Investor shall have the right to make
      a
      public disclosure in the form of a press release, public advertisement or
      otherwise, of such material non-public information without the prior approval
      by
      the Company, the Subsidiaries, or any of its or their respective officers,
      directors, employees or agents. Buyers shall not have any liability to the
      Company, the Subsidiaries or any of its or their respective officers, directors,
      employees, stockholders or agents for any such disclosure. Notwithstanding
      anything to the contrary herein, in the event that the Company believes that
      a
      notice or communication to any Buyer or Investor contains material, non-public
      information relating to the Company or any of the Subsidiaries, the Company
      so
      shall indicate to such Buyer or Investor contemporaneously with delivery of
      such
      notice or communication, and such indication shall provide such Buyer or
      Investor the means to refuse to receive such notice or communication; and in
      the
      absence of any such indication, the holders of the Securities shall be allowed
      to presume that all matters relating to such notice or communication do not
      constitute material, non-public information relating to the Company or any
      of
      the Subsidiaries. Upon receipt or delivery by the Company or any of the
      Subsidiaries of any notice in accordance with the terms of the Transaction
      Documents, unless the Company has in good faith determined that the matters
      relating to such notice do not constitute material, non-public information
      relating to the Company or the Subsidiaries, the Company shall within one (1)
      Business Day after any such receipt or delivery publicly disclose such material,
      non-public information pursuant to the securities laws.

     

    k. Pledge
      of Securities.
      The
      Company acknowledges and agrees that the Securities may be pledged by Buyers
      or
      their transferees (each, including any such Buyer, an “Investor”)
      in
      connection with a bona fide margin agreement or other bona fide loan secured
      by
      the Securities. The pledge of Securities shall not be deemed to be a transfer,
      sale or assignment of the Securities hereunder, and no Investor effecting any
      such pledge of Securities shall be required to provide the Company with any
      notice thereof or otherwise make any delivery to the Company pursuant to this
      Agreement or any other Transaction Document, including Section
      2(f)
      of this
      Agreement. The Company hereby agrees to execute and deliver such documentation
      as a pledgee of the Securities may reasonably request in connection with a
      pledge of the Securities to such pledgee by an Investor.

      which might result in the termination by the Pension Benefit Guaranty
      Corporation (the “PBGC”)
      of any

      the
      PBGC of its intention to seek termination of any Plan or appointment of a

    (iii) Environmental

      manufacture handling, production or disposal of any Hazardous Materials in
      violation of the requirements of any Environmental Law or any other
      environmental, health or safety matter which affects such Person or its business
      operations or assets or any properties at which such Person has transported,
      stored or disposed of any Hazardous Materials, unless the foregoing could not
      reasonably be expected to have a Material Adverse Effect. 

     

    (iv) Default;
      Material Adverse Effect.
      Promptly advise Buyers of any material adverse change in the business, property,
      assets, operations or financial condition of such Person, any other Material

    m. Compliance
      with Laws and Maintenance of Permits.
      During
      the Sub Note Period, the Company shall, and shall cause each of the Subsidiaries
      to, maintain all governmental consents, franchises, certificates, licenses,
      authorizations, approvals and permits, the lack of which would reasonably
      be
      expected to have a Material Adverse Effect and to remain in compliance with
      all
      Laws (including Environmental Laws and Laws relating to taxes, employer and
      employee contributions and similar items, securities, ERISA or employee health
      and safety) the failure with which to comply would have a Material Adverse
      Effect on such Person. Following any determination by Marquis in its sole
      discretion that there is non-compliance, or any condition which requires any
      action by or on behalf of the Company or any of the Subsidiaries in order to
      avoid non-compliance, with any Environmental Law, Marquis may, at the Company’s
      expense, cause an independent environmental engineer reasonably acceptable

      prepare and deliver to Buyers a report setting forth the results of such tests,
      a proposed plan for remediation and an estimate of the costs thereof, and the
      Company and/or its applicable Subsidiary(ies) shall promptly undertake such
      recommended or necessary remedial actions as shall be necessary to avoid a
      Material Adverse Effect

     

    n. Inspection

      During
      the Sub Note Period, the Company shall, and shall cause each of the Subsidiaries
      to, permit the holders of the Warrant and the Sub Notes, or any Persons

      reasonable times and upon prior written notice, and, without unreasonable
      hindrance or delay, to inspect, audit, check and make extracts from such
      Person’s books, records, journals, orders, receipts and any correspondence and
      other data relating to such Person’s business or any transactions between the
      parties hereto, and shall have the right to make such verification concerning
      such Person’s business as such holder may consider reasonable under the
      circumstances. Notwithstanding anything to the contrary herein, upon written
      request to the Company by any such holder, the Company shall promptly provide
      such holder with any financial, operating or other type of information requested
      by such holder, subject to such holder’s execution of a confidentiality
      agreement reasonably acceptable to the Company with respect to such information,
      which execution shall constitute a waiver, with respect to any material
      non-public information regarding the Company and the Subsidiaries provided
      to
      such holder directly in response to such written request, of the restriction
      herein on the Company’s disclosure to such holder of material non-public
      information. The Company shall pay to any such holder all costs and
      out-of-pocket expenses incurred by such holder in the exercise of its rights
      hereunder, and all of such fees, costs and expenses shall constitute
      Indebtedness under the Sub Notes held by such holder, shall be payable on demand
      by the Company to such holder and, until paid, shall bear interest at the
      Applicable Interest Rate (as defined in the Sub Notes).

      companies that regularly insure Persons engaged in businesses similar to that
      of
      the Company or applicable Subsidiary, such coverage and the premiums payable
      in
      respect thereof to be acceptable in scope and amount to Buyer. Original (or
      certified) copies of such policies have been or shall be, no later than ten
      (10)
      days prior to the Closing Date, delivered to Buyer, together with evidence
      of
      payment of all premiums therefor.

    q. Taxes.
      During

      any extensions granted by the applicable taxing authority, including taxes
      imposed by federal, state or municipal agencies, and shall cause any Liens
      for
      taxes to be promptly released; provided, that Person shall have the right to
      contest the payment of such taxes in good faith by appropriate proceedings
      so
      long as (i) the amount so contested is shown on such Person’s financial
      statements; (ii) the contesting of any such payment does not give rise to a
      Lien
      for taxes; (iii) such Person keeps on deposit with the Collateral Agent (such
      deposit to be held without interest) an amount of money which, in the sole
      judgment of the Collateral Agent, is sufficient to pay such taxes and any
      interest or penalties that may accrue thereon; and (iv) if such Person fails
      to
      prosecute such contest with reasonable diligence, the Collateral Agent may
      apply
      the money so deposited in payment of such taxes. If the Company or a Subsidiary
      fails to pay any such taxes (other than taxes not yet due, subject to an
      extension or subject to a contest) and in the absence of any such contest by
      such Person, holders of the Warrant or Sub Notes may (but shall be under no
      obligation to) advance and pay any sums required to pay any such taxes and/or
      to
      secure the release of any Lien therefor, and any sums so advanced by such
      holders shall constitute Indebtedness of the Company to such holders, shall
      be
      payable by the Company to such holders on demand, and, until paid, shall bear
      interest at the Applicable Interest Rate (as defined in the Sub Notes).

      marks and trademarks to continue its business as presently proposed to be
      conducted by it (including as
      described to Buyers prior to the date hereof) or as hereafter conducted by
      it,
      unless the failure to maintain any of the foregoing would not reasonably be
      expected to have a Material Adverse Effect. 

     

    s. Patriot
      Act, Investor Secrecy Act and Office of Foreign Assets Control.
      As
      required by federal law and each
      Buyer’s
      policies and practices, Buyers may need to obtain, verify and record certain
      customer identification information and documentation in connection with opening
      or maintaining accounts, or establishing or continuing to provide services,
      and,
      from the date of this Agreement until the end of the Reporting Period, the
      Company agrees to, and shall cause each of the Subsidiaries to, provide such
      information to Buyers.

      customary drilling title opinion with respect to such drillsite. Upon written
      request to the Company by a Buyer, the Company shall promptly provide such
      Buyer
      with a copy of such drilling title opinion, subject to such Buyer’s execution of
      a confidentiality agreement reasonably acceptable to the Company with respect
      thereto; provided,
      however, that any such request shall constitute a waiver, with respect to any
      material non-public information regarding the Company and the Subsidiaries
      contained in such drilling title opinion, of the restriction herein on the
      Company’s disclosure to such Buyer of material non-public
      information.

      warranties that speak as of a specific date, which shall be true and correct
      as
      of such date) and the Company shall have performed, satisfied and complied

      Closing Date, which opinion(s) will collectively address, among other things,
      certain federal laws and the laws of the States of Delaware and New York

      reasonably satisfactory to such Buyer.

    8. INDEMNIFICATION.
      

     

    a. In
      consideration of each Buyer’s execution and delivery of the Transaction
      Documents and acquiring the Securities thereunder and in addition to all of
      the
      Company’s and the Subsidiaries’ other obligations under the Transaction
      Documents, the Company shall defend, protect, indemnify and hold harmless such
      Buyer and each other holder of the Securities and all of their stockholders,
      partners, officers, directors, members, managers, employees and direct or
      indirect investors and any of the foregoing Persons’ agents or other
      representatives (including those retained in connection with the transactions
      contemplated by this Agreement) (collectively, the “Indemnitees”)
      from
      and against any and all actions, causes of action, suits, claims, losses, costs,
      penalties, fees, liabilities and damages, and expenses in connection therewith
      (irrespective of whether any such Indemnitees is a party to the action for
      which
      indemnification hereunder is sought), and including reasonable attorneys’ fees
      and disbursements (the “Indemnified
      Liabilities”),
      incurred by any Indemnitees as a result of, or arising out of, or relating
      to
      (i) any misrepresentation or breach of any representation or warranty made
      by the Company or any of the Subsidiaries in any of the Transaction Documents
      or
      any other certificate, instrument or document contemplated hereby or thereby,
      (ii) any breach of any covenant, agreement or obligation of the Company or
      any of the Subsidiaries contained in the Transaction Documents or any other
      certificate, instrument or document contemplated hereby or thereby,
      (iii) any cause of action, suit or claim brought or made by any party
      (other than a cause of action, suit or claim that is brought or made by the
      Company on its own behalf and is not a stockholder derivative action, suit
      or
      claim) against such Indemnitees and arising out of or resulting from the
      execution, delivery, performance or enforcement of the Transaction Documents
      in
      accordance with the terms thereof or any other certificate, instrument or
      document contemplated hereby or thereby in accordance with the terms thereof
      (other than a cause of action, suit or claim brought or made against an
      Indemnitee by such Indemnitee’s owners, investors or Affiliates), (iv) any
      other transaction financed or to be financed in whole or in part, directly
      or
      indirectly, with the proceeds of the issuance of the Securities, or (v) the
      status of such Buyer or holder of the Securities as an investor in the Company
      (other than a cause of action, suit or claim brought by the Company against
      such
      Buyer or holder relating to a breach of any representation or warranty made
      by
      such Buyer or holder herein). To the extent that the foregoing undertaking
      by
      the Company may be unenforceable for any reason, the Company shall make the
      maximum contribution to the payment and satisfaction of each of the Indemnified
      Liabilities that is permissible under applicable law. 

    
      
         

      

      
        46

        
          

        

      

      
         

      

    

    b. Promptly
      after receipt by an Indemnitee under this Section
      8
      of
      notice of the commencement of any action or proceeding (including any
      governmental action or proceeding) involving any Indemnified Liabilities, such
      Indemnitee shall, if any claim for Indemnified Liabilities in respect thereof
      is
      to be made against the Company under this Section
      8, deliver
      to the Company a written notice of the commencement thereof, and the Company
      shall have the right to participate in, and, to the extent the Company so
      desires, to assume control of the defense thereof with counsel mutually
      satisfactory to the Company and the Indemnitee, as the case may be. In any
      such
      proceeding, any Indemnitee may retain its own counsel, but, except as provided
      in the following sentence, the fees and expenses of that counsel will be at
      the
      expense of that Indemnitee, as the case may be, unless (i) the Company and
      the
      Indemnitee, as applicable, shall have mutually agreed to the retention of that
      counsel, (ii) the Company does not assume the defense of such proceeding in
      a
      timely manner or (iii) in the reasonable opinion of counsel retained by the
      Company, the representation by such counsel for the Indemnitee and the Company
      would be inappropriate due to actual or potential differing interests between
      such Indemnitee and any other party represented by such counsel in such
      proceeding. The Company shall pay reasonable fees for only one separate legal
      counsel (plus any local counsel) for the Investors, and such legal counsel
      shall
      be selected by Investors holding at least 2/3 in interest of the outstanding
      Sub
      Notes (or, if no Sub Notes are outstanding, of the outstanding Warrant). The
      Indemnitee shall cooperate fully with the Company in connection with any
      negotiation or defense of any such action by the Company and shall furnish
      to
      the Company all information reasonably available to the Indemnitee which relates
      to such action. The Company shall keep the Indemnitee fully apprised at all
      times as to the status of the defense or any settlement negotiations with
      respect thereto. The Company shall not be liable for any settlement of any
      action, claim or proceeding effected without its prior written consent;
provided,
      however, that the Company shall not unreasonably withhold, delay or condition
      its consent. The Company shall not, without the prior written consent of the
      Indemnitee, consent to entry of any judgment or enter into any settlement or
      other compromise with respect to any pending or threatened action or claim
      in
      respect of which indemnification or contribution may be or has been sought
      hereunder (whether or not the Indemnitee is an actual or potential party to
      such
      action or claim) which does not include as an unconditional term thereof the
      giving by the claimant or plaintiff to such Indemnitee of a release from all
      liability in respect to such litigation and such settlement shall not include
      any admission as to fault on the part of the Indemnitee. Following
      indemnification as provided for hereunder, the Company shall be subrogated
      to
      all rights of the Indemnitee with respect to all third parties, firms or
      corporations relating to the matter for which indemnification has been made.
      The
      failure to deliver written notice to the Company within a reasonable time of
      the
      commencement of any such action shall not relieve such Company of any liability
      to the Indemnitee under this Section
      8,
      except
      to the extent that the Company is prejudiced in its ability to defend such
      action.

     

    c. The
      indemnification required by this Section
      8
      shall be
      made by periodic payments of the amount thereof during the course of the
      investigation or defense, as and when bills are received or Indemnified
      Liabilities are incurred.

     

    d. The
      indemnity agreements contained herein shall be in addition to (i) any cause
      of
      action or similar right of the Indemnitee against the Company or others, and
      (ii) any liabilities the Company may be subject to pursuant to the
      law.

    
      
         

      

      
        47

        
          

        

      

      
         

      

    

    9. GOVERNING
      LAW; MISCELLANEOUS.

     

    a. Governing
      Law; Jurisdiction; Jury Trial.
      All
      questions concerning the construction, validity, enforcement and interpretation
      of this Agreement shall be governed by the internal laws of the State of New
      York, without giving effect to any choice of law or conflict of law provision
      or
      rule (whether of the State of New York or any other jurisdiction) that would
      cause the application of the laws of any jurisdiction other than the State
      of
      New York. Each party hereby irrevocably submits to the exclusive jurisdiction
      of
      the state and federal courts sitting in the New York City, borough of Manhattan,
      for the adjudication of any dispute hereunder or in connection herewith or
      with
      any transaction contemplated hereby or discussed herein, and hereby irrevocably
      waives, and agrees not to assert in any suit, action or proceeding, any claim
      that it is not personally subject to the jurisdiction of any such court, that
      such suit, action or proceeding is brought in an inconvenient forum or that
      the
      venue of such suit, action or proceeding is improper. Each party hereby
      irrevocably waives personal service of process and consents to process being
      served in any such suit, action or proceeding by mailing a copy thereof to
      such
      party at the address for such notices to it under this Agreement and agrees
      that
      such service shall constitute good and sufficient service of process and notice
      thereof. Nothing contained herein shall be deemed to limit in any way any right
      to serve process in any manner permitted by law. The parties acknowledge that
      each Buyer has executed each of the Transaction Documents to be executed by
      it
      in the State of New York and will have made the payment of any purchase price
      to
      be paid by it on the Closing Date pursuant to any Transaction Document from
      its
      bank account located in the State of New York. EACH PARTY HEREBY IRREVOCABLY
      WAIVES ANY RIGHT IT MAY HAVE, AND AGREES NOT TO REQUEST, A JURY TRIAL FOR THE
      ADJUDICATION OF ANY DISPUTE HEREUNDER OR IN CONNECTION HEREWITH OR ARISING
      OUT
      OF THIS AGREEMENT OR ANY TRANSACTION CONTEMPLATED HEREBY.

     

    b. Counterparts.
      This
      Agreement and any amendments hereto may be executed and delivered in one or
      more
      counterparts, and by the different parties hereto in separate counterparts,
      each
      of which when executed shall be deemed to be an original, but all of which
      taken
      together shall constitute one and the same agreement, and shall become effective
      when counterparts have been signed by each party hereto and delivered to the
      other parties hereto, it being understood that all parties need not sign the
      same counterpart. In the event that any signature to this Agreement or any
      amendment hereto is delivered by facsimile transmission or by e-mail delivery
      of
      a “.pdf” format data file, such signature shall create a valid and binding
      obligation of the party executing (or on whose behalf such signature is
      executed) with the same force and effect as if such facsimile or “.pdf”
signature page were an original thereof. At the request of any party each other
      party shall promptly re-execute an original form of this Agreement or any
      amendment hereto and deliver the same to the other party. No party hereto shall
      raise the use of a facsimile machine or e-mail delivery of a “.pdf” format data
      file to deliver a signature to this Agreement or any amendment hereto or the
      fact that such signature was transmitted or communicated through the use of
      a
      facsimile machine or e-mail delivery of a “.pdf” format data file as a defense
      to the formation or enforceability of a contract, and each party hereto forever
      waives any such defense.

     

    c. Headings.
      The
      headings of this Agreement are for convenience of reference and shall not form
      part of, or affect the interpretation of, this Agreement.

     

    d. Severability.
      If any
      provision of this Agreement shall be invalid or unenforceable in any
      jurisdiction, such invalidity or unenforceability shall not affect the validity
      or enforceability of the remainder of this Agreement in that jurisdiction or
      the
      validity or enforceability of any provision of this Agreement in any other
      jurisdiction.

    e. Entire
      Agreement; Amendments.
      This
      Agreement, together with the other Transaction Documents, supersedes all other
      prior oral or written agreements between each Buyer, the Company, the
      Subsidiaries, their Affiliates and Persons acting on their behalf with respect
      to the matters discussed herein, and this Agreement, together with the other
      Transaction Documents and the other instruments referenced herein and therein,
      contains the entire understanding of the parties with respect to the matters
      covered herein and therein and, except as specifically set forth herein or
      therein, neither the Company nor such Buyer makes any representation, warranty,
      covenant or undertaking with respect to such matters. As of the date of this
      Agreement, there are no unwritten agreement between the parties with respect
      to
      the matters discussed herein. No provision of this Agreement may be amended,
      modified or supplemented other than by an instrument in writing signed by the
      Company and the Buyers that purchased at least two-thirds (2/3) of the aggregate
      original principal amount of the Sub Notes on the Closing Date or, if prior
      to
      the Closing Date, by the Buyers listed on the Schedule
      of Buyers
      as being
      obligated to purchase at least two-thirds (2/3) of the aggregate original
      principal amount of the Sub Notes. Any such amendment shall bind all holders
      of
      the Notes and the Warrant. No such amendment shall be effective to the extent
      that it applies to less than all of the Notes or Warrant then
      outstanding.

     

    f. Notices.
      Any
      notices, consents, waivers or other communications required or permitted to
      be
      given under the terms of this Agreement must be in writing and will be deemed
      to
      have been delivered: (i) upon receipt, when delivered personally; (ii) upon
      receipt, when sent by facsimile (provided

    g. Successors
      and Assigns.
      This
      Agreement shall be binding upon and inure to the benefit of the parties and
      their respective successors and assigns, including any purchasers of the
      Securities. The Company shall not assign this Agreement or any rights or
      obligations hereunder without the prior written consent of the holders of at
      least two-thirds (2/3) of the aggregate principal of the Sub Notes then
      outstanding, including by merger or consolidation. Buyers may assign some or
      all
      of their rights hereunder without the consent of the Company; provided,
      however, that any such assignment shall not release a Buyer from its obligations
      hereunder unless such obligations are assumed by such assignee (as evidenced
      in
      writing) and the Company has consented to such assignment and assumption, which
      consent shall not be unreasonably withheld. Notwithstanding anything to the
      contrary contained in the Transaction Documents, Buyers shall be entitled to
      pledge the Securities in connection with a bona fide margin account or other
      loan or financing arrangement secured by the Securities. 

     

    h. No
      Third Party Beneficiaries.
      This
      Agreement is intended for the benefit of the parties hereto and their respective
      permitted successors and assigns and, to the extent provided in Section
      8
      hereof,
      each Indemnitee, and is not for the benefit of, nor may any provision hereof
      be
      enforced by, any other Person.

     

    i. Survival.
      Unless
      this Agreement is terminated under Section
      9(k),
      the
      representations and warranties of the Company and Buyers contained in
Sections 2
      and
3,
      the
      agreements and covenants set forth in Sections 4,
      5
      and
9,
      and the
      indemnification and contribution provisions set forth in Section
      8,
      shall
      survive the Closing. The Company acknowledges and agrees that the provisions
      of
Section
      15
      of the
      Sub Notes shall survive the redemption, repayment or surrender of such Sub
      Notes.

     

    j. Further
      Assurances.
      Each
      party shall do and perform, or cause to be done and performed, all such further
      acts and things, and shall execute and deliver all such other agreements,
      certificates, instruments and documents, as the other party may reasonably
      request in order to carry out the intent and accomplish the purposes of this
      Agreement and the consummation of the transactions contemplated
      hereby.

     

    k. Termination.
      In the
      event that the Closing shall not have occurred on or before the third Business
      Day following the date of this Agreement due to the Company’s or Buyers’ failure
      to satisfy the conditions set forth in Sections
      6
      and
7
      above
      (and the nonbreaching party’s failure to waive such unsatisfied condition(s)),
      the nonbreaching party (i.e., the Company in the case of a breach by a Buyer,
      and any Buyer in the case of a breach by the Company) shall have the option
      to
      terminate this Agreement with respect to such breaching party at the close
      of
      business on such date without liability of any party to any other party;
provided,
      however, that if this Agreement is terminated pursuant to this Section
      9(k),
      the
      Company shall be obligated to pay each Buyer (so long as such Buyer is not
      a
      breaching party) its transaction fees and reimbursement amounts as set forth
      in
Section
      4(i)
      as if
      such Buyer had purchased the Sub Notes (and in the case of Marquis, the
      Warrant).

     

    l. No
      Strict Construction.
      The
      language used in this Agreement will be deemed to be the language chosen by
      the
      parties to express their mutual intent, and no rules of strict construction
      will
      be applied against any party.

    
      
         

      

      
        51

        
          

        

      

      
         

      

    

    m. Remedies.
      Buyers
      and each holder of the Securities shall have all rights and remedies set forth
      in the Transaction Documents and all rights and remedies that Buyers and holders
      have been granted at any time under any other agreement or contract and all
      of
      the rights that Buyers and holders have under any law. Any Person having any
      rights under any provision of this Agreement shall be entitled to enforce such
      rights specifically (without any requirement to post a bond or other security
      or
      prove actual damages, which requirements each of the parties waives to the
      fullest extent permitted by Law), to recover damages by reason of any breach
      of
      any provision of this Agreement and to exercise all other rights granted by
      law.

     

    n. Rescission
      and Withdrawal Right.
      Notwithstanding anything to the contrary contained in (and without limiting
      any
      similar provisions of) the Transaction Documents, whenever a Buyer exercises
      a
      right, election, demand or option under a Transaction Document and the Company
      or any of the Subsidiaries does not timely perform its related obligations
      within the periods therein provided, then such Buyer may rescind or withdraw,
      in
      its sole discretion from time to time upon written notice to the Company, any
      relevant notice, demand or election in whole or in part without prejudice to
      its
      future actions and rights.

     

    o. Payment
      Set Aside.
      To the
      extent that the Company or any of the Subsidiaries makes a payment or payments
      to a Buyer pursuant to this Agreement, the Sub Notes, the Guaranty or any other
      Transaction Document or a Buyer enforces or exercises its rights hereunder
      or
      thereunder, and such payment or payments or the proceeds of such enforcement
      or
      exercise or any part thereof are subsequently invalidated, declared to be
      fraudulent or preferential, set aside, recovered from, disgorged by or are
      required to be refunded, repaid or otherwise restored to the Company or any
      of
      the Subsidiaries, by a trustee, receiver or any other Person under any law
      (including any bankruptcy law, state or federal law, common law or equitable
      cause of action), then to the extent of any such restoration the obligation
      or
      part thereof originally intended to be satisfied shall be revived and continued
      in full force and effect as if such payment had not been made or such
      enforcement or setoff had not occurred. 

     

    p. Transfer
      Agent Instructions.
      The
      Company shall issue irrevocable instructions to its transfer agent in the form
      attached hereto as Exhibit
      F
      (the
“Irrevocable
      Transfer Agent Instructions”),
      and
      any subsequent transfer agent, to issue certificates or credit shares to the
      applicable balance accounts at DTC, registered in the name of each Buyer or
      its
      nominee(s), for Warrant Shares upon exercise of the Warrant or Option Shares
      upon exercise of the Investor Share Option (as applicable), in such amounts
      as
      specified from time to time by each Buyer to the Company. On or before November
      14, 2008, the Company shall deliver to each Buyer a fully executed copy of
      the
      Irrevocable Transfer Agent Instructions (including execution by the Company’s
      transfer agent). The Company warrants that no instruction other than the
      Irrevocable Transfer Agent Instructions referred to in this Section
      9(p) and
      stop
      transfer instructions to give effect to Section
      2(g)
      will be
      given by the Company to its transfer agent and that the Securities shall
      otherwise be freely transferable on the books and records of the Company as
      and
      to the extent provided in this Agreement. If any Buyer provides the Company
      with
      an opinion of counsel, in a generally acceptable form, to the effect that a
      public sale, assignment or transfer of the Securities may be made without
      registration under the 1933 Act or such Buyer provides the Company with
      reasonable assurance that the Securities can be sold pursuant to Rule 144
      without any restriction as to the number of securities acquired as of a
      particular date that can then be immediately sold, the Company shall permit
      the
      transfer and, in the case of the Warrant Shares or the Option Shares, promptly
      instruct its transfer agent to issue one or more certificates or credit shares
      to the applicable balance accounts at DTC in such name and in such denominations
      as specified by such Buyer and without any restrictive legend. The Company
      acknowledges that a breach by it of its obligations hereunder will cause
      irreparable harm to each Buyer by vitiating the intent and purpose of the
      transactions contemplated hereby. Accordingly, the Company acknowledges that
      the
      remedy at law for a breach of its obligations under this Section
      9(p)
      will be
      inadequate and agrees, in the event of a breach or threatened breach by the
      Company of the provisions of this Section
      9(p),
      that
      each Buyer shall be entitled, in addition to all other available remedies,
      to an
      injunctive order and/or injunction restraining any breach and requiring
      immediate issuance and transfer, without the necessity of showing economic
      loss
      and without any bond or other security being required.

    q. Interpretative
      Matters.
      Unless
      the context otherwise requires, (a) all references to Sections, Schedules
      or Exhibits are to Sections, Schedules or Exhibits contained in or attached
      to
      this Agreement, (b) each accounting term not otherwise defined in this Agreement
      has the meaning assigned to it in accordance with GAAP, (c) words in the
      singular or plural include the singular and plural and pronouns stated in either
      the masculine, the feminine or neuter gender shall include the masculine,
      feminine and neuter, and (d) the use of the word “including” in this
      Agreement shall be by way of example rather than limitation.
      All
      references herein and in each of the other Transaction Documents to
“dollars”
or
      “$”
shall
      mean the lawful money of the United States of America.

     

    r. Independent
      Nature of the Buyers.
      The
      obligations of each Buyer hereunder are several and not joint with the
      obligations of any other Buyer, and no Buyer shall be responsible in any way
      for
      the performance of the obligations of any other Buyer hereunder. Each Buyer
      shall be responsible only for its own representations, warranties, agreements
      and covenants hereunder. The decision of each Buyer to acquire the Securities
      pursuant to this Agreement has been made by such Buyer independently of any
      other Buyer and independently of any information, materials, statements or
      opinions as to the business, affairs, operations, assets, properties,
      liabilities, results of operations, condition (financial or otherwise) or
      prospects of the Company or any of the Subsidiaries which may have been made
      or
      given by any other Buyer or by any agent or employee of any other Buyer, and
      no
      Buyer or any of its agents or employees shall have any liability to any other
      Buyer (or any other Person or entity) relating to or arising from any such
      information, materials, statements or opinions. Nothing contained herein, and
      no
      action taken by any Buyer pursuant hereto or thereto, shall be deemed to
      constitute the Buyers as a partnership, an association, a joint venture or
      any
      other kind of entity, or create a presumption that the Buyers are in any way
      acting in concert or as a group with respect to such obligations or the
      transactions contemplated hereby. Each Buyer shall be entitled to independently
      protect and enforce its rights, including the rights arising out of this
      Agreement, the Bridge Notes and the other Transaction Documents, and it shall
      not be necessary for any other Buyer to be joined as an additional party in
      any
      proceeding for such purpose.

     

    s. Waiver
      of Old Warrant Anti-Dilution Provisions.
      Longview hereby waives any adjustment to the Warrant Exercise Price (as defined
      in the Old Warrant (and in the New Longview Warrant)), or to the number of
      shares of Common Stock issuable upon exercise of the Old Warrant (or of the
      New
      Longview Warrant), pursuant to Section 8 of the Old Warrant (or of the New
      Longview Warrant), solely to the extent that such adjustment would directly
      result from the Company’s issuance of the Warrant, the Warrant Shares, the Sub
      Notes, the Option Shares, the Warrants (as defined in the Securities Purchase
      Agreement), the Warrant Shares (as defined in the Securities Purchase
      Agreement), the Override Exchange Shares or the Conversion Shares, all in
      accordance with the terms and conditions set forth in this Agreement, the
      Securities Purchase Agreement, the Warrants and the Sub Notes.

    IN
      WITNESS WHEREOF,
      Buyers
      and the Company have caused this Securities Exchange Agreement to be duly
      executed as of the date first written above.
