    NOW
      THEREFORE,
      the
      Company and each of the Buyers, severally and not jointly, hereby agree as
      follows:

     

    1. PURCHASE
      AND SALE OF NOTES,

    b. The
      Closing Date.
      The

      shall
      be 10:00 a.m., New York City time, on the first Business Day following the

      The

      LLP, 525 West Monroe Street, Suite 1900, Chicago, Illinois 60661, or at such

      which
      instructions shall (among other things) specify that an aggregate of $5,000,000

    d. Overrides.
      

     

    (i) On
      the
      Closing Date, the Company shall, and shall cause each of the Subsidiaries that
      own any Real Property (as defined in Section
      3(bb))
      to,
      deliver to each of the Buyers Overrides, each duly and validly executed by
      the
      Company and each of the Subsidiaries (as applicable), providing such Buyer
      with
      perpetual overriding royalty interests, effective from the Closing Date, in
      the

      (3%), multiplied by such Buyer’s Allocation Percentage. 

    
      
        
        

      

      
        4

        
          

        

      

      
        
        

      

    

    (ii) During
      the period commencing on (and including) the one-year anniversary of the Closing
      Date and terminating on (and excluding) the two-year anniversary of the Closing
      Date, the Company shall have the right to purchase from the Buyers all (but
      not
      less than all) of the Overrides issued to the Buyers prior to the one-year
      anniversary of the Closing Date (the Override
      Exchange”),
      by
      delivery of a written notice of election (the date of delivery of the written
      notice, the “Override
      Exchange Election Date,”
and
      each such written notice, an “Override
      Exchange Notice”)
      to
      each of the Buyers, provided that the Conditions to Override Exchange (as set
      forth in Section
      1(d)(iii))
      are
      satisfied (or waived in writing by each of the Buyers). An Override Exchange
      Notice shall be irrevocable by the Company. The Company shall not be entitled
      or
      permitted to effect the Override Exchange, or deliver any Override Exchange
      Notice, unless the Company takes the same action, at the same time, with respect
      to all of the Overrides. No later than ten (10) Business Days following the
      Override Exchange Election Date, each of the Company and Buyers holding a
      majority in interest of the outstanding Overrides shall select an oil and gas
      industry recognized appraiser, independent of the Company, the Subsidiaries
      and
      each of the Buyers (each, an “Appraiser”
and
      together, the “Appraisers”),
      to
      determine the Fair Market Value of the Overrides held by each of the Buyers.
      The
      designation of an Appraiser by the Company and by Buyers holding a majority
      in
      interest of the outstanding Overrides, respectively, shall not be made without
      the prior consent of the other, which consent shall not be unreasonably
      withheld. Each Appraiser shall be directed to deliver a written report (each,
      a
“Valuation
      Report”)
      to the
      Company and each of the Buyers as to such Appraiser’s valuation of the Overrides
      (in the aggregate and as to those held by each Buyer) as promptly as
      practicable, and in no event later than forty-five (45) days after the Override
      Exchange Election Date (the “Valuation
      Deadline”).
      No
      later than three (3) Business Days prior to the Override Exchange Date, each
      Buyer shall deliver to the Company a written notice (an “Override
      Exchange Election Notice”)
      as to
      Buyer’s election (A) to receive Override Exchange Shares as (I) Common Override
      Exchange Shares or (II) on or after the Preferred Authorization (as defined
      in
Section
      4(z)),
      Preferred Override Exchange Shares, or a combination of Common Override Exchange
      Shares and Preferred Override Exchange Shares and, if a combination, as to
      the
      respective proportions thereof; or (B) to receive Warrants (“Override
      Warrants”)
      to
      purchase Warrant Shares (“Override
      Warrant Shares”)
      at an
      initial exercise price per share of $0.01. If the Company has delivered an
      Override Exchange Notice in accordance with this Section
      1(d)(ii) and
      each
      of the Conditions to Override Exchange (as set forth in Section
      1(d)(iii))
      are
      satisfied (or waived in writing by the Buyers), then, on the Override Exchange
      Date, the Company shall deliver to each of the Buyers a number (rounded to
      the
      nearest whole number, with 0.5 being rounded up) of Override Exchange Shares
      (or, if so elected by such Buyer in its Override Election Notice, Override
      Warrants to purchase a number of Warrant Shares) equal to the quotient of (X)
      the Fair Market Value of the Overrides held by such Buyer, divided by (Y) the
      arithmetic average of the closing price per share of the Common Stock on the
      Principal Market (as defined in Section
      3(s))
      on each
      of the twenty (20) consecutive Trading Days immediately preceding the Override
      Exchange Date (the “Applicable
      Average Share Price”).
      The
      failure of the Company to deliver the Override Exchange Shares (or Override
      Warrants, as applicable) in full on the Override Exchange Date shall constitute
      an Event of Default (as defined in the Notes). For purposes hereof, the
“Fair
      Market Value”
of
      the
      Overrides shall mean (I) if both Valuation Reports have been delivered on or
      prior to the Valuation Deadline, the arithmetic average of the valuations of
      the
      Overrides set forth in the Valuation Reports, (II) if only one Valuation Report
      is delivered on or prior to the Valuation Deadline, the valuation set forth
      in
      such Valuation Report, and (III) if neither Valuation Report has been delivered
      by the Valuation Deadline, the valuation set forth in the first Valuation Report
      delivered after the Valuation Deadline (the date that is two (2) Business Days
      after the Valuation Deadline, or, if neither Valuation Report has been delivered
      by the Valuation Deadline, the date that is two (2) Business Days after delivery
      of the first Valuation Report, being referred to herein as the “Valuation
      Determination Date”);
      “Override
      Exchange Date”
shall
      mean the twenty-first (21st) Trading Day after the Valuation Determination
      Date;
“Override
      Exchange Shares”
means,
      at each Buyer’s election as set forth in such Buyer’s Override Exchange Election
      Notice, shares of Common Stock (“Common
      Override Exchange Shares”),
      and/or, at any time on or after the Preferred Authorization, shares of
      convertible preferred stock of the Company having terms as provided in
Section
      1(d)(iv)
      (“Preferred
      Override Exchange Shares”);
      provided
      that, if
      any Buyer fails to deliver an Override Exchange Election Notice as required
      hereby, it shall be deemed to have elected to receive all of its Override
      Exchange Shares as Preferred Override Exchange Shares if the Preferred
      Authorization has occurred, or as Override Warrants if it has not; and
“Trading
      Day”
means
      any day on which the Common Stock is traded on its Principal Market;
provided
      that
“Trading Day” shall not include any day on which the Principal Market is open
      for trading for less than 4.5 hours.

    
      
        
        

      

      
        5

        
          

        

      

      
        
        

      

    

    (iii) For
      purposes of this Section
      1(d),
      “Conditions
      to Override Exchange”
means
      the following conditions: on each day during the period beginning on and
      including the Override Exchange Election Date and ending on and including the
      Override Exchange Date, (A) the Common Stock is quoted on the OTC Bulletin
      Board
      or listed on a national securities exchange and the Common Stock has not been
      suspended from trading on any such market or exchange nor (I) shall delisting
      or
      suspension by any such market or exchange have been threatened in writing by
      such exchange or (II) shall the Company have fallen below the minimum listing
      maintenance requirements of such exchange, and the Company otherwise satisfies
      all of the requirements for continued listing of the Common Stock on such
      exchange, (B) the Company and each of the Subsidiaries is (I) incorporated
      or
      organized and validly existing under the laws of the jurisdiction of its
      incorporation or organization and (II) in good standing under the requirements
      of any applicable regulatory authority, (C) the Company has filed all reports
      and other materials required to be filed under the Securities Exchange Act

      there does not exist any Event of Default (as defined in the Notes), (E) the

      the
      Override Exchange Shares (or Override Warrant Shares, as applicable) have been
      registered for public resale by the Buyers pursuant to an effective registration
      statement under the 1933 Act, in accordance with a registration rights agreement
      in form and substance acceptable to each of the Buyers. In the event that any
      of
      the Conditions to Override Exchange shall not be satisfied (and such failure
      is
      not waived in writing by all of the Buyers), the Override Exchange Notice shall
      be void and the Override Exchange contemplated thereby shall not be given any
      force or effect.

     

    (iv) The
      parties hereto agree that the Preferred Override Exchange Shares shall be
      perpetual, shall not bear dividends, shall be convertible into Common Stock
      on a
      one-for-one basis (i.e., one share of Common Stock for each Preferred Override
      Exchange Share, subject to a limitation on conversion substantially similar
      to
      the limitation on exercise set forth in the Warrants and subject to adjustment
      for stock splits, stock dividends, stock combinations, recapitalizations and
      similar events), shall be senior upon liquidation, winding up or dissolution
      of
      the Company to the Common Stock and any other class of preferred stock of the
      Company and shall have such other designations, powers, preferences and
      relative, participating, optional and other special rights, and qualifications,
      limitations and restrictions as shall be agreed upon by the Company and Marquis
      (all of the designations, powers, preferences and relative, participating,
      optional and other special rights, and qualifications, limitations and
      restrictions of the Preferred Shares being referred to as the “Preferred
      Rights”).
      The
      Company and Marquis agree to negotiate in good faith to agree upon the Preferred
      Rights (other than the Preferred Rights already set forth in this Section
      1(d)(iv))
      prior
      to the Override Exchange Election Date. The Preferred Rights, when and as agreed
      upon by the Company and Marquis, shall be promptly fixed by the board of
      directors of the Company (the “Board”)
      and
      set forth in a Certificate of Designations to be filed with the Secretary of
      State of the State of Delaware after the Preferred Authorization, in a form
      acceptable to each of the Company and Marquis (the “Certificate
      of Designations”).

    (v) Notwithstanding
      anything to the contrary contained in this Agreement, no Buyer will be entitled
      to receive, and the Company will not issue to any Buyer on any date, any Common
      Override Exchange Shares in excess of that number of shares of Common Stock
      that
      would cause such Buyer and its affiliates to beneficially own 4.99% of the
      shares of Common Stock outstanding immediately after such issuance. A Buyer’s
      delivery of an Override Exchange Election Notice shall constitute a
      representation that, upon issuance to such Buyer of the number of Common
      Override Exchange Shares requested in such Override Exchange Election Notice,
      such Buyer and its affiliates will not beneficially own, more than 4.99% of
      the
      shares of Common Stock immediately after giving effect to such issuance, and
      in
      no event shall the Company issue to such Buyer on any Option Exchange Date
      a
      number of shares of Common Stock in excess of the number of Common Override
      Exchange Shares that such Buyer requests in such Buyer’s Override Exchange
      Election Notice. For purposes of the foregoing, the aggregate number of shares
      of Common Stock beneficially owned by a Buyer and its affiliates shall include
      the number of Common Override Exchange Shares to be issued pursuant to this
      Agreement on the applicable Override Exchange Date in accordance with this
      Section
      1(d)(v),
      but
      shall exclude all other shares of Common Stock otherwise issuable to such Buyer
      and its affiliates pursuant to this Agreement and all other shares of Common
      Stock that would be issuable upon exercise, conversion or exchange of the
      unexercised, unconverted or unexchanged portion of any other securities of
      the
      Company beneficially owned by such Buyer and its affiliates (including the
      Warrants and any other warrants or convertible notes or preferred stock) subject
      to a limitation on conversion, exercise or exchange analogous to the limitation
      contained herein. Except as set forth in the preceding sentence, for purposes
      of
      this paragraph, beneficial ownership shall be calculated in accordance with
      Section 13(d) of the 1934 Act. For purposes of this Agreement, in determining
      the number of outstanding shares of Common Stock, a Buyer may rely on the number
      of outstanding shares of Common Stock as reflected in (1) the Company’s most
      recent Periodic Report (as defined in Section
      4(e)),
      (2) a
      more recent public announcement by the Company or (3) any other notice by the
      Company or its transfer agent setting forth the number of shares of Common
      Stock
      outstanding. Upon the written request of any Buyer, the Company shall promptly,
      but in no event later than one (1) Business Day following the receipt of such
      request, confirm in writing to any such Buyer the number of shares of Common
      Stock then outstanding. In any case, the number of outstanding shares of Common
      Stock shall be determined after giving effect to the issuance of Common Override
      Exchange Shares to such Buyer and its affiliates pursuant to this Agreement,
      and
      the conversion, exercise or exchange of securities of the Company by such Buyer
      and its affiliates, since the date as of which such number of outstanding shares
      of Common Stock was reported.

    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 Notes (along with the related Guarantees) and the
      Warrants purchased by such Buyer hereunder, (ii) upon any exercise of the
      Warrants (including any Override Warrants) will acquire the Warrant Shares
      (including Override Warrant Shares, as applicable) issuable upon such exercise
      thereof, (iii) in the event of any Override Exchange will acquire Override
      Exchange Shares or Override Warrants (as applicable), and (iv) upon any
      conversion of any Preferred Override Exchange Shares, will acquire the shares
      of
      Common Stock issuable upon conversion thereof (the “Conversion
      Shares”
and,
      collectively with the Notes, the Guarantees, the Warrants (including any
      Override Warrants) and the Warrant Shares (including any Override 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.

     

    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 (as defined in Section
      3(b)).
      Such
      Buyer understands that its investment in the Securities involves a high degree
      of risk. Such Buyer has sought such accounting, legal and tax advice as it
      has
      considered necessary 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):

    
      
        
        

      

      
        9

        
          

        

      

      
        
        

      

    

    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). 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

      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),
      the
      Company holds all right, title and interest in and to 100% of the Capital Stock,
      equity or similar interests of each of the Subsidiaries, in each case, free

      transactions contemplated hereby or the agreements and instruments to be entered

      to enter into the Transaction Documents and perform its obligations thereunder.

      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”

      Lease Obligation”
means,

      parties hereto in connection with the transactions contemplated hereby and
      thereby (collectively, 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 delivery of the Transaction
      Documents by the Company and each of the Subsidiaries and the consummation
      by
      the Company and each of the Subsidiaries of the transactions contemplated hereby
      and thereby, including the issuance of the Notes and the Warrants and the
      reservation for issuance and the issuance of the Warrant Shares issuable upon
      exercise of the Warrants (including the Override Warrant Shares issuable upon
      exercise of any Override Warrants), and the Override Exchange Shares upon any
      Override Exchange, have been (and upon the Preferred Authorization, the
      Conversion Shares issuable upon conversion of any Preferred Override Exchange
      Shares will have been) duly authorized by the respective boards of directors,
      members, managers, stockholders or other equityholders, as applicable, of the
      Company and each of the Subsidiaries, and no further consent or authorization
      is
      required by the Company, any of the Subsidiaries or any of their respective
      boards of directors, members, managers, 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 creditors’ rights generally and
      general principles of equity. As of the Closing, 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 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

      other
      governing documents, as applicable, of any such Person; (ii) conflict with,
      or constitute a breach or default (or an event which, with the giving of notice
      or passage of time or both, constitutes 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 respect to, any agreement, indenture

      business of the Company and the Subsidiaries has not been and is not being
      conducted, in violation of any Law of any Governmental Entity except as could
      not, individually or in the aggregate, reasonably be expected to have a Material

      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

      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

      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

      all material respects with the securities laws. Except as set forth on
Schedule

      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

      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))

      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,

      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

      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

    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
      of
      any fact that would reasonably lead a creditor to do so. Neither the Company
      nor
      any Subsidiary is as of the date this representation is made, nor after giving
      effect to the transactions contemplated hereby or by any of the other
      Transaction Documents, will be Insolvent (as defined below). As used in this
      Agreement, “Insolvent”

      assets is less than the amount required to pay such Person’s total indebtedness,

      liabilities, subordinated, contingent or otherwise, as such debts and
      liabilities become absolute and matured, (iii) such Person intends to
      incur, prior to the second anniversary of the date this representation is made,
      or believes that it will incur, prior to the second anniversary of the date
      this
      representation is made, debts that would be beyond its ability to pay as such
      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
      and is proposed to be conducted. Except as disclosed on Schedule
      3(g),
      since
      December 31, 2005, neither the Company nor any of the Subsidiaries has declared
      or paid any dividends or sold any assets outside of the ordinary course of
      business. Except as disclosed on Schedule
      3(g),
      since
      February 14, 2008, neither the Company nor any of the Subsidiaries has had
      any
      capital expenditures outside the ordinary course of its
      business.

      or body pending or, to the Company’s Knowledge, threatened against or affecting
      the Company or any of the Subsidiaries or any of their respective assets, and
      (ii) no officer of the Company nor, to the Company’s Knowledge, any officer or
      director of the Company or holder of more than five percent (5%) of the
      outstanding securities of the Company or any of the Subsidiaries has been
      involved in securities-related Litigation during the past ten (10) years. No
      Litigation disclosed on Schedule
      3(h)
      has, has
      had or, if determined adversely to the Company or any of the Subsidiaries,
      could
      reasonably be expected to have a Material Adverse Effect.

     

    i. Full
      Disclosure; No Undisclosed Events, Liabilities, Developments or
      Circumstances.

      circumstances exist that could reasonably be expected to be, cause or have
      a
      Material Adverse Effect. Other than the liabilities and obligations under this
      Agreement or as set forth on Schedule
      3(i),

      only liabilities of the Company or any Subsidiary (whether fixed or unfixed,

      inchoate, liquidated or unliquidated, or secured or unsecured, and regardless
      of
      when any action, claim, suit or proceeding with respect thereto is instituted)
      are the liabilities reflected on Schedule
      3(i),
      as of
      the date of this Agreement, all of which will be reflected on the Pro Forma
      Balance Sheet (as defined in Section
      4(y)).
      As of
      the Closing Date, the only liabilities of the Company (whether fixed or unfixed,
      known or unknown, absolute or contingent, asserted or unasserted, choate or
      inchoate, liquidated or unliquidated, or secured or unsecured and regardless
      of
      when any action, claim, suit or proceeding with respect thereto is instituted)
      are the liabilities reflected on Schedule
      3(i),
      as of
      the date of this Agreement, all of which will be reflected on the Pro Forma
      Balance Sheet. As of the Closing Date, the only liabilities of the Company
      (whether fixed or unfixed, known or unknown, absolute or contingent, asserted
      or
      unasserted, choate or inchoate, liquidated or unliquidated, or secured or
      unsecured and regardless of when any action, claim, suit or proceeding with

      those
      assumed or created pursuant to, or as a result of, this Agreement and the other
      Transaction Documents and the consummation of the Closing, and liabilities

      obligations of not more than $50,000 for
      operating expenses incurred in the ordinary course of business consistent with
      past practices subsequent to June 30, 2008, all of which will be reflected
      on
      the Pro Forma Balance Sheet. No representation or warranty or other statement
      made by the Company or the Subsidiaries in this Agreement or any of the other
      Transaction Documents, the Schedules hereto or any certificate or instrument
      delivered pursuant to this Agreement contains any untrue statement or omits
      to
      state a material fact necessary to make any such statement, in light of the
      circumstances in which it was made, not misleading.

    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
      any
      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
      the
      transactions contemplated hereby and thereby is merely incidental to such
      Buyer’s purchase of the Securities. The Company further represents to each Buyer
      that the decision of each of the Company and each of the Subsidiaries to enter
      into the Transaction Documents has been based solely on the independent
      evaluation by such Person and its representatives.

     

    k. No
      General Solicitation.
      Except
      as set forth on Schedule
      3(k),
      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
      Person, (iv) is controlled by such first Person or (v) shares or is under common
      control with such first Person; and “control”
or
      “controls”
means
      that a Person has the power, direct or indirect, to conduct or govern the
      policies of another Person; provided
      however,
      that Longview shall not be considered to be an Affiliate of the Company for
      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
      of
      any authority.

     

    m. Dilutive
      Effect.
      The
      Company understands and acknowledges that the number of Warrant Shares
      (including any Override Warrant Shares, as applicable) that the Company is
      obligated to issue upon exercise of the Warrants (including any Override
      Warrants) will increase in certain circumstances. The Company further
      acknowledges that its obligation to issue the Warrant Shares (including any
      Override Warrant Shares) upon exercise of the Warrants including any Override
      Warrants), respectively, 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 Warrants (including any Override Warrants) 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.

      as set forth on Schedule
      3(n),
      neither
      the Company nor any of the Subsidiaries is involved in any labor union dispute

      of
      the employees of either the Company or any of the Subsidiaries is or has been
      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
      is a party to a collective bargaining agreement. Except as set forth on
Schedule

      executive officer (as defined in Rule 3b-7 under the 1934 Act) nor any other
      individual whose termination would be required to be disclosed on a Current
      Report on Form 8-K but that has not been so reported, has notified the Company
      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
      employment and wages and hours.

      the
      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
      and defensible title thereto, free and clear of all Liens (other than Permitted
      Liens) and other matters affecting title to such leasehold that could impair
      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
      3(bb),
      all of
      the Real Property Leases are valid and in full force and effect and are
      enforceable against all parties thereto. Except as set forth on Schedule
      3(bb),
      neither
      the Company nor any of the Subsidiaries nor, to the Company’s Knowledge, any
      other party thereto is in default in any material respect under any of such
      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
      as
      set forth on Schedule
      3(bb),
      there
      are no pending or threatened condemnation, eminent domain or similar
      proceedings, or litigation or other proceedings affecting the Real Property,
      or
      any portion or portions thereof. Except as set forth on Schedule
      3(bb),
      there
      are no pending or threatened requests, applications or proceedings to alter
      or
      restrict any zoning or other use restrictions applicable to the Real Property
      that would interfere with the conduct of the Company’s or any of the
      Subsidiaries’ business as conducted or proposed to be conducted (including as
      described to Buyers) at the time this representation is made. Except as set
      forth on Schedule
      3(bb),
      there
      are no restrictions applicable to the Real Property that would interfere with
      the Company’s or any Subsidiary’s making an assignment or granting of a
      leasehold or other mortgage to Buyers as contemplated by the Security Documents,
      including any requirement under any Real Property Leases requiring the consent
      of, or notice to, any lessor of any such Real Property. Except as set forth
      on
Schedule
      3(bb),
      all of
      the Real Property is located in the State of Texas. Except as set forth on
      Schedule
      3(bb),
      all of
      the wells on the Real Property have been drilled and completed at legal
      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
      are no joint operating agreements applicable to the Real Property. Neither
      the
      Company nor any of the Subsidiaries will be obligated, as of the Closing Date
      or
      thereafter, including by virtue of a prepayment arrangement, make-up right
      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
      past
      production by any such owner, the Company or the Subsidiaries or any of their
      respective predecessors in excess of the share to which it was entitled with
      respect to such Real Property. Except as set forth on Schedule
      3(bb),
      no
      Person has any call upon, option to purchase or similar right to obtain
      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
      long as oil, gas or other minerals are produced in paying quantities or they
      are
      otherwise maintained by operations.

      as
      promptly as reasonably practicable following the first date on which the Company

      of
      trading of the Common Stock on the Principal Market. The Company shall pay
      all
      fees and expenses in connection with satisfying its obligations under this

    i. Expenses.
      Subject
      to Section
      9(k)
      below,
      at the Closing, the Company shall pay each Buyer a reimbursement amount equal

      previously paid by the Company) incurred in connection with the Closing,
      including without limitation fees and expenses of attorneys, investigative
      and
      other consultants and travel costs and all other expenses relating to

      transactions contemplated thereby. The aggregate amount payable to each Buyer
      pursuant to the preceding sentence at Closing shall be withheld as an off-set

      in limitation thereof, following the Closing, the Company shall promptly
      reimburse each Buyer, each holder of Securities and the Collateral Agent for
      all
      of the respective out-of-pocket fees, costs and expenses incurred thereby in
      connection with any amendment, modification or waiver of any of the Transaction
      Documents, the enforcement of such Person’s rights and remedies under any of the

      Collateral Agent in any of the Collateral (as defined in the Security
      Agreement).

    j. Disclosure
      of Transactions and Other Material Information. 

     

    (i) Not
      later
      than 5:30 p.m. (New York City time) on the second (2nd)
      Business Day following the execution and delivery of this Agreement, the Company
      shall file the Announcing 8-K with the SEC. The “Announcing
      Form 8-K”
(A)
      shall describe the terms of the transactions contemplated by this Agreement
      and
      the other Transaction Documents, including the issuance of the Notes and the
      Warrants, (B) shall include as exhibits to such Form 8-K this Agreement
      (including the schedules hereto), the form of Note, the form of Warrant, the
      form of Security Agreement, the form of Guaranty, the form of Pledge Agreement,
      the form of Mortgage, the form of Account Control Agreement, the form of
      Supplemental Account Control Agreement and the form of Conveyance of Limited
      Overriding Royalty Interests, and (C) shall include any other information
      required to be disclosed therein pursuant to any securities laws or other
      Laws.

     

    (ii) Subject
      to the agreements and covenants set forth in this Section
      4(j),
      the
      Company shall not issue any press releases or any other public statements with
      respect to the transactions contemplated hereby or disclosing the name of any
      Buyer; provided,
      however, that the Company shall be entitled, without the prior approval of
      any
      Buyer, to make any press release or other public disclosure with respect to
      such
      transactions (A) in substantial conformity with the Announcing Form 8-K and
      contemporaneously therewith and (B) as is required by applicable Law, including
      as is required by Form 8-K or any successor form thereto (provided
      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.

     

    l. Notices.
      From the
      date of this Agreement until the first date following the Closing Date on which
      no Notes are outstanding and the Security Agreement has terminated (the period
      ending on such latest date, the “Security
      Period”),
      the
      Company shall and shall cause each of the Subsidiaries to:

     

    (i) Locations.
      Promptly (but in no event less than ten (10) days prior to the occurrence
      thereof) notify Buyers of the proposed opening of any new place of business
      or
      new location of Collateral (as defined in the Security Agreement), the closing
      of any existing place of business or location of Collateral, any change in
      the
      location of such Person’s books, records and accounts (or copies thereof), the
      opening or closing of any post office box, the opening or closing of any bank
      account or, if any of the Collateral consists of Goods (as defined in the
      Security Agreement) of a type normally used in more than one state, the use
      of
      any such Goods in any state other than a state in which such Person has
      previously advised a Buyer that such Goods will be used.

     

    (ii) Names
      and Trade Names.
      Notify
      Buyers in writing (A) at least thirty (30) days in advance of any change in
      such
      Person’s legal name and (B) within ten (10) days of the change of the use of any
      trade name, assumed name, fictitious name or division name not previously
      disclosed to all Buyers in writing.

    
      
        
        

      

      
        36

        
          

        

      

      
        
        

      

    

    (iii) ERISA
      Matters.
      Promptly notify Buyers of (x) the occurrence of any “reportable event” (as
      defined in the Employee Retirement Income Security Act of 1974, as amended
      (“ERISA”)),
      which might result in the termination by the Pension Benefit Guaranty
      Corporation (the “PBGC”)
      of any
      employee benefit plan (“Plan”)
      covering any officers or employees of such Person, any benefits of which are,
      or
      are required to be, guaranteed by the PBGC, (y) receipt of any notice from
      the
      PBGC of its intention to seek termination of any Plan or appointment of a
      trustee therefor or (z) its intention to terminate or withdraw from any
      Plan.

     

    (iv) Environmental
      Matters.
      Immediately notify Buyers upon becoming aware of any investigation, proceeding,
      complaint, order, directive, claim, citation or notice with respect to any
      non-compliance with or violation of the requirements of any Environmental Law
      by
      such Person or the generation, use, storage, treatment, transportation,
      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. 

     

    (v) 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
      Adverse Effect, or the occurrence of any Event of Default (as defined in any
      Note) or the occurrence of any event which, if uncured, will become an Event
      of
      Default after notice or lapse of time (or both). 

     

    All
      of
      the foregoing notices shall be provided by the Company or applicable Subsidiary
      to such Buyers in writing.

     

    m. Compliance
      with Laws and Maintenance of Permits.
      During
      the Security 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
      to
      Marquis to conduct such tests of the relevant site(s) as are appropriate and
      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.

    
      
        
        

      

      
        37

        
          

        

      

      
        
        

      

    

    n. Inspection
      and Audits.
      During
      the Security Period, (i) the Company shall, and shall cause each of the
      Subsidiaries to, permit Buyers, or any Persons designated by a Buyer, to call
      at
      such Person’s places of business at any reasonable times and upon prior written
      notice, and, without unreasonable hindrance or delay, to inspect, examine and
      audit the Collateral and 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, the Collateral or any
      transactions between the parties hereto, and shall have the right to make such
      verification concerning such Person’s business as such Buyer may consider
      reasonable under the circumstances; and (ii) each Buyer, through their officers,
      employees or agents shall have the right, at any time and from time to time,
      in
      such Buyer’s name, to verify the validity, amount or any other matter relating
      to any of the Company’s and the Subsidiaries’ Accounts (as defined in the
      Security Agreement), by mail, telephone, telecopy, electronic mail or otherwise.
      Notwithstanding anything to the contrary herein, upon written request to the
      Company by any Buyer, the Company shall promptly provide such Buyer with any
      financial, operating or other type of information requested by such Buyer,
      subject to such Buyer’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 Buyer directly
      in
      response to such written request, of the restriction herein on the Company’s
      disclosure to such Buyer of material non-public information. The Company shall
      pay to such Buyer all costs and out-of-pocket expenses incurred by such Buyer
      in
      the exercise of its rights hereunder, and all of such fees, costs and expenses
      shall constitute Indebtedness under the Note of such Buyer, shall be payable
      on
      demand by the Company to such Buyer and, until paid, shall bear interest at
      the
      Applicable Interest Rate (as defined in the Notes).

     

    o. Insurance.
      During
      the Security Period, the Company shall, and shall cause each of the Subsidiaries
      to:

     

    (i) Keep
      the
      Collateral properly housed (to the extent possible) and insured for the full
      insurable value thereof against loss or damage by fire, theft, explosion,
      sprinklers, collision (in the case of motor vehicles) and such other risks
      with
      companies that regularly insure Persons engaged in businesses similar to that
      of
      such Person, such coverage and the premiums payable in respect thereof to be
      acceptable in scope and amount to the Collateral Agent. Original (or certified)
      copies of such policies of insurance have been or shall be, no later than ten
      (10) days prior to the Closing Date, delivered to Buyers, together with evidence
      of payment of all premiums therefor, and shall contain an endorsement, in form
      and substance reasonably acceptable to Collateral Agent, showing loss under
      such
      insurance policies payable to Collateral Agent. Such endorsement, or an
      independent instrument furnished to the Collateral Agent, shall provide that
      the
      insurance company shall give the Collateral Agent at least thirty (30) days
      written notice before any such policy of insurance is altered or canceled and
      that no act, whether willful or negligent, or default of the Company or the
      applicable Subsidiary or any other Person shall affect the right of the
      Collateral Agent to recover under such policy of insurance in case of loss
      or
      damage. In addition, the Company or the applicable Subsidiary shall cause to
      be
      executed and delivered to the Collateral Agent an assignment of proceeds of
      its
      business interruption insurance policies (if any).

    
      
        
        

      

      
        38

        
          

        

      

      
        
        

      

    

    (ii) Maintain,
      at its expense, such public liability and third party property damage insurance
      with companies that regularly insure Persons engaged in businesses similar
      to
      that of such Person, such coverage and the premiums payable in respect thereof
      to be acceptable in scope and amount to the Collateral Agent. 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 Buyers, together with evidence
      of
      payment of all premiums therefor; each such policy shall contain an endorsement
      showing the Collateral Agent as an additional insured thereunder and providing
      that the insurance company shall give Collateral Agent at least thirty (30)
      days
      written notice before any such policy shall be altered or canceled.

     

    (iii) If
      the
      Company or any of the Subsidiaries at any time or times hereafter shall fail
      to
      obtain or maintain any of the policies of insurance required above or to pay
      any
      premium relating thereto, any Buyer, without waiving or releasing any obligation
      or default by the Company hereunder, may (but shall be under no obligation
      to)
      obtain and maintain such policies of insurance and pay such premiums and take
      such other actions with respect thereto as such Buyer deems advisable. Such
      insurance, if obtained by a Buyer, may, but need not, protect the Company’s and
      the Subsidiaries’ interests or pay any claim made by or against the Company and
      the Subsidiaries with respect to the Collateral. Such insurance may be more
      expensive than the cost of insurance the Company and the Subsidiaries may be
      able to obtain on their own and may be cancelled only upon the Company and
      the
      Subsidiaries’ providing evidence that they have obtained the insurance as
      required above. All sums disbursed by Buyers in connection with any such
      actions, including court costs, expenses, other charges relating thereto and
      reasonable attorneys’ fees, shall constitute Indebtedness under the Notes of the
      applicable Buyers, shall be payable on demand by the Company to such Buyers
      and,
      until paid, shall bear interest at the Applicable Interest Rate (as defined
      in
      the Notes).

     

    p. Collateral.
      During
      the Security Period, the Company shall and shall cause the Subsidiaries to
      maintain the Collateral in good condition, repair and order shall make all
      necessary repairs to the Equipment (as defined in the Security Agreement) and
      replacements thereof so that the operating efficiency and the value thereof
      shall at all times be preserved and maintained, subject to normal wear and
      tear
      after the Closing Date.

     

    q. Taxes.
      During
      the Security Period, the Company shall and shall cause each of the Subsidiaries
      to file all required tax returns and pay all of its taxes when due, subject
      to
      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, a Buyer 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 Buyers shall constitute Indebtedness under the Notes of the
      applicable Buyers, shall be payable by the Company to such Buyers on demand,
      and, until paid, shall bear interest at the Applicable Interest Rate (as defined
      in the 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.

      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

    (iv) With
      respect to any Production Proceeds (as defined in the Mortgages) received by
      Company or any of the Subsidiaries during the Security Period which constitute
      (A) payment of oil or gas proceeds received on account of, or for the benefit

      and development rights, concessions, working interests and participation
      interests and hydrocarbon transportation facilities and businesses reasonably
      related thereto or in furtherance thereof, and (B) preserve, renew and keep
      in

      Subsidiaries shall be certificated or otherwise represented in tangible
      form.

      would prohibit or forgive it from paying all or any portion of any principal
      of,
      or interest or premium on any of the Notes as contemplated herein or therein,
      wherever enacted, now or at any time hereafter in force, or which may affect

      law,
      and covenants that it will not, by resort to any such law, hinder, delay or

      or
      other assets intended to be substituted therefor, (5) attaching an officer’s
      certificate certifying that the Permitted Collateral Disposition is in
      compliance with each of the requirements of clause (ii) of the immediately
      preceding sentence, and (6) attaching the form of release requested by the
      Company or its applicable Subsidiary to be authorized or, if necessary, executed
      by the Secured Parties (as defined in the Security Agreement) or the Collateral

      Subsidiary or securities convertible, exchangeable or exercisable into or for
      debt or equity
      securities of the Company or any Subsidiary (including debt securities with
      an
      equity component) or (z) engage in “farm-out” financing transactions or similar
      transactions which do not have operating obligations by the financing party
      as a

      Offering”),
      unless, after such Person has received an offer regarding a Future Offering
      that
      it has a bona fide intention to accept, such Person shall have first delivered
      to each Buyer (or designees appointed by respective Buyers) written notice
      (the
“Future
      Offering Notice”)
      reporting that it has received and is prepared to accept such offer and
      providing such Buyer an option (the “Buyer
      Purchase Option”)
      to
      purchase up to twenty-five percent (25%) of the total amount of securities,
      rights or interests to be issued or sold in such Future Offering, multiplied
      by
      such Buyer’s Allocation Percentage (the limitations referred to in this sentence

      Raising Limitations”).
      No
      Future Offering Notice shall contain any material non-public information

      of
      any Buyer made within five (5) Business Days after its receipt of a Future
      Offering Notice (an “Additional
      Information Request”),
      the
      Company shall provide each Buyer with such additional information regarding
      the
      proposed Future Offering, including the name of the purchaser, and the terms
      and
      conditions and use of proceeds thereof, as such Buyer shall reasonably request.
      Each Buyer may exercise its Buyer Purchase Option by delivering written notice
      (the “Buyer
      Purchase Notice Date”)
      to the
      Company within five (5) Business Days after the later of (i) the Buyer’s receipt
      of a Future Offering Notice or (ii) the Buyer’s receipt of all of the
      information reasonably requested by the Buyer in an Additional Information
      Request, which notice shall state the quantity or percentage of securities,
      rights or interests being offered in the Future Offering that the Buyer will
      purchase. The Company or the Subsidiary, as appropriate, shall have sixty (60)
      days following the Buyer Purchase Notice Date to sell the securities, rights
      or
      interests of the Future Offering (other than the securities, rights or interests
      to be purchased by Buyers pursuant to this Section
      5(t)),
      upon
      terms and conditions no more favorable to the purchasers thereof than specified
      in the Future Offering Notice. The exercise of a Buyer Purchase Option shall
      be
      contingent upon, and contemporaneous with, the consummation of such Future
      Offering; provided,
      that
      notwithstanding a Buyer’s exercise of the Buyer Purchase Option with respect to
      a particular Future Offering, the determination to complete any such Future
      Offering shall be within the Company’s sole discretion. In connection with such
      consummation, each Buyer (if it exercises its Buyer Purchase Option) shall
      deliver to the Company duly and properly executed originals of any documents
      reasonably required by the Company to effectuate such Future Offering, together
      with payment of the purchase price for the securities, rights or interests
      being
      purchased by such Buyer in such Future Offering, and the Company or the
      Subsidiary, as appropriate, shall promptly issue to such Buyer the securities,
      rights or interests purchased thereby. In the event the Company or the
      Subsidiary, as appropriate, has not sold such securities, rights or interests
      of
      the Future Offering within such 60-day period, then the Company and the
      Subsidiaries shall not thereafter issue or sell such securities, rights or
      interests or any other securities, rights or interests subject to this
Section
      5(t) without
      first offering such securities, rights or interests to such Buyer in the manner
      provided in this Section
      5(t).
      Such
      Buyer shall not be required to participate or exercise its right of
      participation with respect to a particular Future Offering in order to exercise
      its right of participation with respect to later Future Offerings. The Capital
      Raising Limitations shall not apply to (i) any transaction involving the
      Company’s issuances of securities, rights or interests (A) as consideration in a
      merger or consolidation (the primary purpose or material result of which is
      not
      to raise or obtain equity capital or cash), (B) in connection with any strategic
      partnership or joint venture (the primary purpose or material result of which
      is
      not to raise or obtain equity capital or cash), or (C) as consideration for
      the
      acquisition of a business, product, license or other assets by the Company
      (the
      primary purpose or material result of which is not to raise or obtain equity
      capital or cash) or (ii) Exempted Issuances (as defined in the Warrants).

    u. Limits
      on Additional Issuances.
      Neither
      the Company nor any Subsidiary shall, in any manner, until at least 180 days
      after the Closing Date, issue or sell any Common Stock, Convertible Securities
      or Options (the “Equity
      Limitation”)
      or
      file any registration statement. The Equity Limitation shall not apply to (i)
      any transaction involving the Company’s issuances of securities (A) as
      consideration in a merger or consolidation (the primary purpose or material
      result of which is not to raise or obtain equity capital or cash), (B) in
      connection with any strategic partnership or joint venture (the primary purpose
      or material result of which is not to raise or obtain equity capital or cash),
      or (C) as consideration for the acquisition of a business, product, license
      or
      other assets by the Company (the primary purpose or material result of which
      is
      not to raise or obtain equity capital or cash),
      or (ii)
      Exempted Issuances (as defined in the Warrants). 

     

    v. No
      Integrated Offering.
      Neither
      the Company nor any of the Subsidiaries, nor any Affiliates of the foregoing
      or
      any Person acting on the behalf of any of the foregoing, shall, directly or
      indirectly, make any offers or sales of any security or solicit any offers
      to
      purchase any security, under any circumstances that would require registration
      of any of the Securities under the 1933 Act or cause the offering of the
      Securities to be integrated with prior offerings by the Company for purposes
      of
      the 1933 Act or the rules or requirements of any regulatory or self-regulatory
      authority.

     

    w. Regulation
      M.
      Neither
      the Company, nor any of the Subsidiaries nor any Affiliates of the foregoing
      will take any action prohibited by Regulation M under the 1934 Act, in
      connection with the offer, sale and delivery of the Securities contemplated
      hereby.

     

    x. Fundamental
      Changes; Line of Business.
      During
      the Reporting Period, the Company shall not, and shall not permit any of the
      Subsidiaries to, (i) except as contemplated by Section
      4(z),
      amend
      its organizational documents or change its fiscal year unless (A) such actions
      could not reasonably be expected to have a Material Adverse Effect; (B) such
      actions would not adversely affect any Buyer or any Buyer’s rights and remedies
      under this Agreement and the other Transaction Documents; and (C) each Buyer
      has
      received at least ten (10) days prior written notice of such amendment or
      change; or (ii) engage in any business other than the business currently
      conducted by the Company and the Subsidiaries, as disclosed in the Company's
      annual report on Form 10-K for the year ended December 31, 2007, and the
      business currently conducted by North Texas.

      provided pursuant to the Security Agreement, in form, scope and substance
      reasonably satisfactory to such Buyer.

     

    (d) The
      Company and the Subsidiaries, as applicable, shall have executed and delivered
      to such Buyer the Notes, the Warrants and the Overrides purchased by such
      Buyer.

      Closing Date, the Company shall have reserved out of its authorized and unissued
      Common Stock, solely for the purpose of effecting (A) the exercise of the
      Warrants (including any Override Warrants) and (B) any issuance of Common Stock
      pursuant to the Override Exchange or upon Conversion of any Preferred Override

      of

      stock combinations or other similar transactions involving the Common Stock
      that

      of
      such state or jurisdiction of incorporation or organization as of a date within
      sixteen (16) days of the Closing Date.

     

    (h) The

    (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. 

    
      
        
        

      

      
        55

        
          

        

      

      
        
        

      

    

    (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 Notes (or, if no Notes are outstanding,
      of the outstanding Warrants). 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.

    
      
        
        

      

      
        56

        
          

        

      

      
        
        

      

    

    (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.

     

    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 the Purchase Price
      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 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 Notes. Any such amendment shall bind all holders of
      the
      Notes and the Warrants. No such amendment shall be effective to the extent
      that
      it applies to less than all of the Notes or Warrants 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
      confirmation of transmission is mechanically or electronically generated and

      with a nationally recognized overnight delivery service, in each case properly
      addressed to the party to receive the same. The addresses and facsimile numbers

      nationally recognized overnight delivery service in accordance with clause
      (i),
      (ii) or (iii) above, respectively.

     

    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 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
      19
      of the
      Notes shall survive the redemption, repayment or surrender of such
      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 the 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 Notes (and in the case of Marquis, the Warrants
      and
      the Overrides).

    
      
        
        

      

      
        60

        
          

        

      

      
        
        

      

    

    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.

     

    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 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. 

    
      
        
        

      

      
        61

        
          

        

      

      
        
        

      

    

    p. Transfer
      Agent Instructions.
      The
      Company shall issue irrevocable instructions to its transfer agent in the form
      attached hereto as Exhibit
      L
      (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 (including any Override Warrant Shares) upon
      exercise of the Warrants (including any Override Warrants) or Conversion Shares
      upon conversion of any Preferred Override Exchange Shares (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 (including any Override Warrant
      Shares) and the Conversion 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.

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

    Sonterra
      Resources, Inc. (f/k/a River Capital Group, Inc.), a Delaware corporation (the
      “Company”),
      hereby certifies that, for Ten United States Dollars ($10.00) and other good
      and
      valuable consideration, the receipt and sufficiency of which are hereby
      acknowledged, Longview Marquis Master Fund, L.P., a British Virgin Island
      limited partnership (“Marquis”),
      the
      registered holder hereof, or its successors or permitted assigns (the
“Holder”),
      is
      entitled, subject to the terms and conditions set forth below, to purchase
      from
      the Company, at any time or times on or after the date hereof, but not after
      11:59 P.M. New York Time on the Expiration Date (as defined herein) ONE MILLION
      FIFTY THOUSAND (1,050,000) fully
      paid nonassessable shares of Common Stock (as defined in Section
      1(b))
      of the
      Company (the “Warrant
      Shares”)
      at the
      Warrant Exercise Price (as defined in Section
      1(b));
      provided,
      however, that in no event shall the Holder be entitled or required to exercise
      this Warrant for a number of Warrant Shares in excess of that number of Warrant
      Shares that, upon giving effect to such exercise, would cause the aggregate
      number of shares of Common Stock beneficially owned by the Holder and its
      Affiliates to exceed 4.99% of the outstanding shares of the Common Stock
      following such exercise. For purposes of the foregoing proviso, the aggregate
      number of shares of Common Stock beneficially owned by the Holder and its
      Affiliates shall include the number of shares of Common Stock issuable upon
      exercise of this Warrant with respect to which the determination of such proviso
      is being made, but shall exclude shares of Common Stock that would be issuable
      upon (i) exercise of the remaining, unexercised Warrants (as defined in Section
      1(b) below) beneficially owned by the Holder and its Affiliates and (ii)
      exercise, conversion or exchange of the unexercised, unconverted or unexchanged
      portion of any other securities of the Company beneficially owned by the Holder
      and its Affiliates subject to a limitation on conversion, exercise or exchange
      analogous to the limitation contained herein. Except as set forth in the
      preceding sentence, for purposes of this paragraph, beneficial ownership shall
      be calculated in accordance with Section 13(d) of the Exchange Act (as defined
      in Section 1(b)). For purposes of this Warrant, in determining the number of
      outstanding shares of Common Stock, a Holder may rely on the number of
      outstanding shares of Common Stock as reflected in (1) the Company’s most recent
      Periodic Report (as defined in Section 1(b)), (2) a more recent public
      announcement by the Company or (3) any other written (including e-mail) notice
      by the Company or its transfer agent setting forth the number of shares of
      Common Stock outstanding. Upon the written request of the Holder, the Company
      shall promptly, but in no event later than two Business Days following the
      receipt of such request, confirm in writing to the Holder the number of shares
      of Common Stock then outstanding. In any case, the number of outstanding shares
      of Common Stock shall be determined after giving effect to the conversion,
      exercise or exchange of securities of the Company, including this Warrant,
      by
      the Holder and its Affiliates since the date as of which such number of
      outstanding shares of Common Stock was reported.

    (a) Subject
      to the terms and conditions hereof, this Warrant may be exercised by the Holder
      hereof then registered on the books of the Company, in whole or in part, at
      any
      time on any Business Day on or after the opening of business on the date hereof

      delivery of a written notice, in the form of the exercise notice attached as
      Exhibit
      A
      hereto
      (the “Exercise
      Notice”),
      of
      such Holder’s election to exercise this Warrant, which notice shall specify the
      number of Warrant Shares to be purchased and, if such exercise is conditioned
      upon consummation of any transaction (an “Exercise
      Trigger Transaction”),
      such
      condition to exercise, (ii) (A) payment to the Company of an amount equal to
      the
      product of the Warrant Exercise Price multiplied by the number of Warrant Shares
      as to which this Warrant is being exercised (such product, the “Aggregate
      Exercise Price”),
      by
      check or wire transfer of funds, or (B) notifying the Company that this Warrant
      is being exercised pursuant to a Cashless Exercise (as defined in Section
      2(e)),
      and
      (iii) if required by Section
      2(f),
      unless
      the Holder has previously delivered this Warrant to the Company and it or a
      new
      replacement Warrant has not yet been delivered to the Holder, the surrender
      to a
      common carrier for overnight delivery to the Company as soon as practicable
      following such date, of this Warrant (or an indemnification undertaking, in
      customary form, with respect to this Warrant in the case of its loss, theft
      or
      destruction pursuant to Section
      10);
      provided,
      that if
      such Warrant Shares are to be issued in any name other than that of the Holder,
      such issuance shall be deemed a transfer and the provisions of Section
      7
      shall be
      applicable. In the event of any exercise of the rights represented by this
      Warrant in compliance with this Section
      2(a),
      on the
      second Business Day (the “Warrant
      Share Delivery Date”)
      following the date of its receipt of the Exercise Notice, the Aggregate Exercise
      Price (or notice of Cashless Exercise) and, if required by Section
      2(f)
      (unless
      the Holder has previously delivered this Warrant to the Company and a new or
      replacement Warrant has not yet been delivered to the Holder), this Warrant
      (or
      an indemnification undertaking, in customary form, with respect to this Warrant
      in the case of its loss, theft or destruction, pursuant to Section
      10)
      (the
“Exercise
      Delivery Documents”)
      (or,
      if the exercise of this Warrant is conditioned upon the consummation of an
      Exercise Trigger Transaction, on the later of such second Business Day and
      the
      date of consummation of such Exercise Trigger Transaction), (A) if the transfer
      agent for the Common Stock is participating in The Depository Trust Company
      (“DTC”)
      Fast
      Automated Securities Transfer Program and the Holder is eligible to receive
      shares through DTC, the Company shall credit such aggregate number of shares
      of
      Common Stock to which the Holder shall be entitled to the Holder’s or its
      designee’s balance account with DTC through its Deposit Withdrawal Agent
      Commission system, or (B) if not, the Company shall issue and deliver to the
      address specified in the Exercise Notice, a certificate, registered in the
      name
      of the Holder or its designee, for the number of shares of Common Stock to
      which
      the Holder shall be entitled. Upon the latest of (x) the date of delivery of
      the
      Exercise Notice, (y) the date of delivery of the Aggregate Exercise Price
      referred to in clause (ii)(A) above or notification to the Company of a Cashless
      Exercise referred to in Section
      2(e),
      and (z)
      if the exercise of this Warrant is conditioned upon the consummation of an
      Exercise Trigger Transaction, the date of such consummation, the Holder shall
      be
      deemed for all purposes to have become the holder of record of the Warrant
      Shares with respect to which this Warrant has been exercised (the date thereof
      being referred to as the “Deemed
      Issuance Date”),
      irrespective of the date of delivery of this Warrant as required by clause
      (iii)
      above or the certificates evidencing such Warrant Shares. 

     

    (b) If
      this
      Warrant is submitted for exercise, as may be required by Section 2(f),
      and
      unless the rights represented by this Warrant shall have expired or shall have
      been fully exercised, the Company shall, as soon as practicable and in no event
      later than five Business Days after receipt of this Warrant (the “Warrant
      Delivery Date”)
      and at
      its own expense, issue a new Warrant identical in all respects to this Warrant,
      except that it shall represent rights to purchase the number of Warrant Shares
      purchasable immediately prior to such exercise under this Warrant, less the
      number of Warrant Shares with respect to which such Warrant is exercised
      (together with, in the case of a Cashless Exercise, the number of Warrant Shares
      surrendered in lieu of payment of the Exercise Price).

     

    
      
        
        

      

      
        -5-

        
          

        

      

      
        
        

      

    

     

    (c) No
      fractional shares of Common Stock are to be issued upon the exercise of this
      Warrant, but rather the number of shares of Common Stock issued upon exercise
      of
      this Warrant shall be rounded up or down to the nearest whole number (with
      0.5
      rounded up).

    (d) If
      the
      Company shall fail for any reason or for no reason (x) to issue and deliver
      to
      the Holder within two Business Days of receipt of the Exercise Delivery
      Documents a certificate for the number of shares of Common Stock to which the
      Holder is entitled or to credit the Holder’s balance account with DTC for such
      number of shares of Common Stock to which the Holder is entitled upon the
      Holder’s exercise of this Warrant or (y) to issue and deliver to the Holder
      on the Warrant Delivery Date a new Warrant for the number of shares of Common
      Stock to which the Holder is entitled pursuant to Section
      2(b),
      if any,
      then the Company shall, in addition to any other remedies under this Warrant
      or
      the Securities Purchase Agreement or otherwise available to the Holder,
      including any indemnification under Section 8 of the Securities
      Purchase Agreement,
      pay as additional damages in cash to the Holder on each day after such second
      Business Day that such shares of Common Stock are not issued and delivered
      to
      the Holder, in the case of clause (x) above, or such third Business Day that
      such Warrant is not delivered, in the case of clause (y) above, an amount equal
      to the sum of (i) 0.5% of the product of (A) the number of shares of Common
      Stock not issued to the Holder on or prior to the Warrant Share Delivery Date
      and (B) the Weighted Average Price of the Common Stock on the Warrant Share
      Delivery Date, in the case of the failure to deliver Common Stock, and (ii)
      if
      the Company has failed to deliver a Warrant to the Holder on or prior to the
      Warrant Delivery Date, 0.5% of the product of (x) the number of shares of Common
      Stock issuable upon exercise of the Warrant as of the Warrant Delivery Date,
      and
      (y) the Weighted Average Price of the Common Stock on the Warrant Delivery
      Date.
      Alternatively, at the election of the Holder made in the Holder’s sole
      discretion, the Company shall pay to the Holder, in lieu of the additional
      damages referred to in the preceding sentence (but in addition to all other
      available remedies that the Holder may pursue hereunder and under the Securities
      Purchase Agreement
      (including indemnification pursuant to Section
      8
      thereof)), 110% of the amount that (A) the Holder’s total purchase price
      (including brokerage commissions, if any) for shares of Common Stock purchased
      to make delivery in satisfaction of a sale by such holder of the shares of
      Common Stock to which the Holder is entitled but has not received upon an
      exercise, exceeds (B) the net proceeds received by the Holder from the sale
      of
      the shares of Common Stock to which the Holder is entitled but has not received
      upon such exercise. If the Holder and the Company are unable to agree upon
      the
      determination of the Weighted Average Price, within one Business Day of such
      disputed determination being submitted to the Holder, then the Company shall
      immediately submit via facsimile the disputed determination of the Weighted
      Average Price to an independent, reputable investment banking firm agreed to
      by
      the Company and the Holder. The Company shall cause the investment banking
      firm
      to perform the determination and notify the Company and the Holder of the
      results no later than two Business Days after the date it receives the disputed
      determinations. Such investment banking firm’s determination shall be deemed
      conclusive absent manifest error.

     

    (e) At
      any
      time after the Warrant Date (as defined in Section
      12),
      the
      Holder may, at its election exercised in its sole discretion, exercise this
      Warrant in whole or in part and, in lieu of making the cash payment otherwise
      contemplated to be made to the Company upon such exercise in payment of the
      Aggregate Exercise Price, elect instead to receive upon such exercise the “Net
      Number” of shares of Common Stock determined according to the following formula
      (a “Cashless
      Exercise”):

     

    
      
        
        

      

      
        -6-

        
          

        

      

      
        
        

      

    

     

    Net
      Number = (A
      x
      B) - (A x C)

    B

    For
      purposes of the foregoing formula:

    

    A=
      the
      total number of shares with respect to which this Warrant is then being
      exercised;

    

    B=
      the
      Weighted Average Price per share of Common Stock on the Trading Day immediately
      preceding the date of the delivery of the Exercise Notice; and

    

    C=
      the
      Warrant Exercise Price then in effect for the applicable Warrant Shares at
      the
      time of such exercise.

     

    (f) Book-Entry.
      Notwithstanding anything to the contrary set forth herein, upon exercise of
      this
      Warrant in accordance with the terms hereof, the Holder shall not be required
      to
      physically surrender this Warrant to the Company unless it is being exercised
      for all of the Warrant Shares represented by the Warrant. The Holder and the
      Company shall maintain records showing the number of Warrant Shares exercised
      and issued and the dates of such exercises or shall use such other method,
      reasonably satisfactory to the Holder and the Company, so as not to require
      physical surrender of this Warrant upon each such exercise. In the event of
      any
      dispute or discrepancy, such records of the Company establishing the number
      of
      Warrant Shares to which the Holder is entitled shall be controlling and
      determinative in the absence of error. Notwithstanding the foregoing, if this
      Warrant is exercised as aforesaid, the Holder may not transfer this Warrant
      unless the Holder first physically surrenders this Warrant to the Company,
      whereupon the Company will forthwith issue and deliver upon the order of the
      Holder a new Warrant of like tenor, registered as the Holder may request,
      representing in the aggregate the remaining number of Warrant Shares represented
      by this Warrant. The Holder, by acceptance of this Warrant, acknowledges and
      agrees that, by reason of the provisions of this paragraph, following exercise
      of any portion of this Warrant, the number of Warrant Shares represented by
      this
      Warrant may be less than the number stated on the face hereof. 

     

    Section
      3. Covenants
      as to Common Stock.
      The
      Company hereby covenants and agrees as follows:

     

    (a) This
      Warrant is, and any Warrants issued in substitution for or replacement of this
      Warrant will upon issuance be, duly authorized and validly issued.

     

    (b) All
      Warrant Shares that may be issued upon the exercise of the rights represented
      by
      this Warrant will, upon issuance and receipt of payment therefor from the Holder
      (including pursuant to a Cashless Exercise, as applicable), be validly issued,
      fully paid and nonassessable and free from all taxes, liens and charges with
      respect to the issue thereof.

     

    
      
        
        

      

      
        -7-

        
          

        

      

      
        
        

      

    

     

    (c) At
      all
      times through (and including) the Expiration Date, the Company will at all
      times
      have authorized and reserved at least 100% of the number of shares of Common
      Stock needed to provide for the exercise of the rights then represented by
      this
      Warrant.

     

    (d) The
      Company shall promptly secure the quotation or listing of the Warrant Shares
      on
      the Principal Market for the Common Stock and each other market or exchange
      on
      which the Common Stock is traded or listed and shall maintain, so long as any
      other shares of Common Stock shall be so traded or listed, such listing of
      all
      Warrant Shares from time to time issuable upon the exercise of this Warrant;
      and
      the Company shall so list, and shall maintain such listing of, any other shares
      of capital stock of the Company issuable upon the exercise of this Warrant
      on
      the Principal Market for such capital stock and each other market or exchange
      on
      which such capital stock is traded or listed. 

     

    (e) The
      Company will not, by amendment of its Certificate of Incorporation or through
      any reorganization, transfer of assets, consolidation, merger, dissolution,
      issue or sale of securities, or any other voluntary action, avoid or seek to
      avoid the observance or performance of any of the terms to be observed or
      performed by it hereunder, but will at all times in good faith assist in the
      carrying out of all the provisions of this Warrant and take all such action
      as
      may reasonably be requested by the Holder in order to protect the exercise
      privilege of the Holder against impairment, consistent with the tenor and
      purpose of this Warrant. Without limiting the generality of the foregoing,
      the
      Company (i) shall not increase the par value of any shares of Common Stock
      receivable upon the exercise of this Warrant above $0.001 per share, and
      (ii) shall take all such actions as may be necessary or appropriate in
      order that the Company may validly and legally issue fully paid and
      nonassessable shares of Common Stock upon the exercise of this Warrant.

     

    (f) This
      Warrant will be binding upon any entity succeeding to the Company by merger,
      consolidation or acquisition of all or substantially all of the Company’s
      assets.

     

    Section
      4. Taxes.
      The
      Company shall pay any and all taxes that may be payable with respect to the
      issuance and delivery of Warrant Shares upon exercise of this
      Warrant.

     

    Section
      5. Warrant
      Holder Not Deemed a Stockholder.
      Except
      as otherwise provided herein, the Holder, as holder of this Warrant, shall
      not
      be entitled to vote or be deemed the holder of shares of the Company for any
      purpose (other than to the extent that the Holder is deemed to be a beneficial
      owner of Warrant Shares under applicable securities laws after taking into
      account the limitation set forth in the first paragraph of this Warrant), nor
      shall anything contained in this Warrant be construed to confer upon the Holder,
      as holder of this Warrant, any of the rights of a stockholder of the Company
      or
      any right to vote, give or withhold consent to any corporate action (whether
      any
      reorganization, issue of stock, reclassification of stock, consolidation,
      merger, conveyance or otherwise), receive notice of meetings, receive dividends
      or subscription rights, or otherwise, prior to the Deemed Issuance Date of
      the
      Warrant Shares that the Holder is then entitled to receive upon the due exercise
      of this Warrant. In addition, nothing contained in this Warrant shall be
      construed as imposing any liabilities on the Holder to purchase any securities
      (except to the extent set forth in an Exercise Notice that has been delivered
      by
      the Holder to the Company) or as a stockholder of the Company, whether such
      liabilities are asserted by the Company or by creditors of the Company.
      Notwithstanding the foregoing, the Company will provide the Holder with copies
      of the same notices (without duplication if the Holder is also a stockholder
      of
      the Company) and other information given to the stockholders of the Company
      generally, contemporaneously with the giving thereof to the
      stockholders.

     

    
      
        
        

      

      
        -8-

        
          

        

      

      
        
        

      

    

     

    Section
      6. Representations
      of Holder.
      The
      Holder, by the acceptance hereof, represents that it is acquiring this Warrant,
      and upon exercise hereof (other than pursuant to a Cashless Exercise) will
      acquire the Warrant Shares, for its own account and not with a view towards,
      or
      for resale in connection with, the public sale or distribution of this Warrant
      or the Warrant Shares, except pursuant to sales registered, or exempted from
      registration, under the Securities Act; provided,
      however, that by making the representations herein, the Holder does not agree
      to
      hold this Warrant or any of the Warrant Shares for any minimum or other specific
      term and reserves the right to dispose of this Warrant and the Warrant Shares
      at
      any time in accordance with or pursuant to a registration statement or an
      exemption under the Securities Act. The Holder further represents, by acceptance
      hereof, that, as of the date of its acquisition of this Warrant, the Holder
      is
      an “accredited investor” as such term is defined in Rule 501(a)(3) of Regulation
      D promulgated by the Securities and Exchange Commission under the Securities
      Act. Each delivery of an Exercise Notice, other than in connection with a
      Cashless Exercise, shall constitute confirmation at such time by the Holder
      of
      the representations concerning the Warrant Shares set forth in the first two
      sentences of this Section
      6,
      unless
      contemporaneously with the delivery of such Exercise Notice, the Holder notifies
      the Company in writing that it is not making such representations (a
“Representation
      Notice”).
      If
      the Holder delivers a Representation Notice in connection with an exercise,
      it
      shall be a condition to the Holder’s exercise of this Warrant and the Company’s
      obligations set forth in Section
      2
      in
      connection with such exercise, that the Company receive such other
      representations as the Company considers reasonably necessary to assure the
      Company that the issuance of its securities upon exercise of this Warrant shall
      not violate any applicable registration requirements of United States or state
      securities laws.

     

    Section
      7. Ownership
      and Transfer.

     

    (a) The
      Company shall maintain at its principal executive offices (or such other office
      or agency of the Company as it may designate by notice to the Holder), a
      register for this Warrant, in which the Company shall record the name and
      address of the person in whose name this Warrant has been issued, as well as
      the
      name and address of each transferee. The Company may treat the person in whose
      name any Warrant is registered on the register as the owner and holder thereof
      for all purposes, notwithstanding any notice to the contrary, but in all events
      recognizing any transfers made in accordance with the terms of this
      Warrant.

     

    (b) This
      Warrant and the rights granted hereunder shall be assignable by the Holder
      hereof in accordance with the Securities Purchase Agreement and upon proper
      surrender of this Warrant, properly endorsed. 

     

    
      
        
        

      

      
        -9-

        
          

        

      

      
        
        

      

    

     

    Section
      8. Adjustment
      of Number of Warrant Shares.
      The
      Warrant Exercise price and the number of shares of Common Stock issuable upon
      exercise of this Warrant shall be adjusted from time to time as follows:

     

    (a) Adjustment
      of Warrant Exercise Price upon Subdivision or Combination of Common
      Stock.
      If the
      Company at any time after the date of issuance of this Warrant subdivides (by
      any stock split, stock dividend, recapitalization or otherwise) its outstanding
      shares of Common Stock into a greater number of shares, the Warrant Exercise
      Price in effect immediately prior to such subdivision will be proportionately
      reduced and the number of shares of Common Stock obtainable upon exercise of
      this Warrant will be proportionately increased. If the Company at any time
      after
      the date of issuance of this Warrant combines (by combination, reverse stock
      split or otherwise) its outstanding shares of Common Stock into a smaller number
      of shares, the Warrant Exercise Price in effect immediately prior to such
      combination will be proportionately increased and the number of shares of Common
      Stock obtainable upon exercise of this Warrant will be proportionately
      decreased. Any adjustment under this Section
      8(a)
      shall
      become effective at the close of business on the date the subdivision or
      combination becomes effective or, if earlier, the record date with respect
      to
      the subdivision or combination.

     

    (b) Certain
      Events.
      If any
      event occurs of the type contemplated by the provisions of this Section
      8
      but not
      expressly provided for by such provisions, then the Company’s Board of Directors
      will make an appropriate adjustment in the Warrant Exercise Price and the number
      of shares of Common Stock obtainable upon exercise of this Warrant so as to
      protect the rights of the Holder; provided that no such adjustment will increase
      the Warrant Exercise Price or decrease the number of shares of Common Stock
      obtainable as otherwise determined pursuant to this Section
      8.

     

    (c) Par
      Value.
      Notwithstanding anything to the contrary contained in this Section
      8,
      if, as
      a result of an adjustment pursuant to this Section
      8,
      the par
      value per share of Common Stock would be greater than the Warrant Exercise
      Price, then the Warrant Price shall be an amount equal to the par value per
      share of the Common Stock but the number of shares the holder of this Warrant
      shall be entitled to purchase shall be such greater number of shares of Common
      Stock as would have resulted from the Warrant Exercise Price that, absent such
      limitation, would have been in effect pursuant to this Section
      8.
      The
      foregoing adjustment shall not constitute a waiver of any claim arising against
      the Company by reason of any covenant contained in Section
      3(e).

     

    Section
      9. Purchase
      Rights; Dividends/Distributions of Assets; Reorganization, Reclassification,
      Consolidation, Merger or Sale.
      

     

    (a) In
      addition to any adjustments pursuant to Section
      8
      above,
      if at any time the Company grants, issues or sells any Options, Convertible
      Securities or rights to purchase stock, warrants, securities or other property
      pro rata to the record holders of any class of its capital stock (the
“Purchase
      Rights”),
      then
      the Holder will be entitled to acquire, upon the terms applicable to such
      Purchase Rights, the aggregate Purchase Rights that the Holder could have
      acquired if the Holder had held the number of shares of Common Stock acquirable
      upon complete exercise of this Warrant immediately before the date on which
      a
      record is taken for the grant, issuance or sale of such Purchase Rights, or,
      if
      no such record is taken, the date as of which the record holders of Common
      Stock
      are to be determined for the grant, issue or sale of such Purchase
      Rights.

     

    
      
        
        

      

      
        -10-

        
          

        

      

      
        
        

      

    

     

    (b) Any
      recapitalization, reorganization, reclassification, consolidation, merger,
      sale
      of all or substantially all of the Company’s assets to another Person or other
      transaction that is effected in such a way that holders of Common Stock are
      entitled to receive (either directly or upon subsequent liquidation) stock,
      securities or assets with respect to or in exchange for Common Stock is referred
      to herein as “Organic
      Change.”
Prior
      to the consummation of any (i) sale of all or substantially all of the Company’s
      assets to an acquiring Person or (ii) other Organic Change following which
      the
      Company is not a surviving entity, the Company will secure from the Person
      purchasing such assets or the successor resulting from such Organic Change
      (in
      each case, the “Acquiring
      Entity”)
      a
      written agreement (in form and substance satisfactory to the Holder) to deliver
      to the Holder, in exchange for this Warrant, a security of the Acquiring Entity
      evidenced by a written instrument substantially similar in form and substance
      to
      this Warrant and satisfactory to the Holder (including, an adjusted Warrant
      Exercise Price equal to the value for the Common Stock reflected by the terms
      of
      such consolidation, merger or sale, and exercisable for a corresponding number
      of shares of Common Stock acquirable and receivable upon exercise of this
      Warrant (without regard to any limitations on exercise), if the value so
      reflected is less than the Warrant Exercise Price in effect immediately prior
      to
      such consolidation, merger or sale). Prior to the consummation of any other
      Organic Change, the Company shall make appropriate provision (in form and
      substance satisfactory to the Holder), to ensure that the Holder will thereafter
      have the right to acquire and receive in lieu of or in addition to (as the
      case
      may be) the shares of Common Stock immediately theretofore acquirable and
      receivable upon the exercise of this Warrant (without regard to any limitations
      on exercise), such shares of stock, securities or assets that would have been
      issued or payable in such Organic Change with respect to or in exchange for
      the
      number of shares of Common Stock that would have been acquirable and receivable
      upon the exercise of this Warrant as of the date of such Organic Change (without
      taking into account any limitations or restrictions on the exerciseability
      of
      this Warrant).

     

    (c) Dividends;
      Distributions of Assets.
      If the
      Company shall declare or make any dividend or other distribution of its assets
      (or rights to acquire its assets) to holders of Common Stock, by way of return
      of capital or otherwise (including any dividend or other distribution of cash,
      stock or other securities, property or options by way of a dividend, spin off,
      reclassification, corporate rearrangement or other similar transaction) (a
      “Distribution”),
      at
      any time after the issuance of this Warrant, then, in each such case, the Holder
      shall be entitled to receive such Distribution, and the Company shall make
      such
      Distribution to the Holder, exactly as if the Holder had exercised this Warrant
      in full, without regard to any limitations on exercise (and, as a result, had
      held all of the shares of Common Stock that the Holder would have received
      upon
      such exercise), immediately prior to the record date for such Distribution,
      or
      if there is no record therefor, immediately prior to the effective date of
      such
      Distribution (but without the Holder’s actually having to so exercise this
      Warrant).

    (d) Notices.

     

    (i) As

      as reasonably practicable, but in no event later than two Business Days, upon
      any adjustment of the Warrant Exercise Price or number of shares of Common
      Stock
      obtainable upon exercise of this Warrant, the Company will give written notice
      thereof to the Holder, setting forth in reasonable detail, and certifying,
      the
      calculation of such adjustment; provided,
      however,
      that
      neither the timing of giving any such notice nor any failure by the Company
      to
      give such a notice shall effect any such adjustment or the effective date
      thereof.

     

    (ii) The
      Company will give written notice to the Holder at least 10 days prior to the
      date on which the Company closes its books or takes a record (A) with respect
      to
      any dividend or distribution upon the Common Stock, (B) with respect to any
      pro
      rata subscription offer to holders of Common Stock or (C) for determining rights
      to vote with respect to any Organic Change, dissolution or liquidation, provided
      that such information shall be made known to the public prior to or
      contemporaneously with such notice being provided to the Holder.

     

    (iii) The
      Company will also give written notice to the Holder at least 10 days prior
      to
      the date on which any Organic Change, dissolution or liquidation will take
      place, provided that such information shall be made known to the public prior
      to
      or contemporaneously with such notice being provided to the Holder.

      mutilated Warrant, the Warrant), issue a new Warrant of like denomination and
      tenor as this Warrant so lost, stolen, mutilated or destroyed.

      Except

      The

      are
      inserted for convenience only and do not constitute a part of this Warrant.
      All
      questions concerning the construction, validity, enforcement and interpretation
      of this Warrant 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.

     

    Section
      15. Rules
      of Construction.
      Unless

      in or attached to this Warrant, (b) 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 (c) the
      use
      of the word “including” in this Warrant shall be by way of example rather than
      limitation.

     

    Section
      16. Signatures. In
      the
      event that any signature to this Warrant 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.
      Notwithstanding the foregoing, the Company shall be obligated to deliver to
      the
      Holder an originally executed Warrant. 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 Warrant 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.
