      to adjustment as set forth below, the aggregate purchase price
      paid by the Buyer to the Sellers for the Interests shall be Nine Million Eight
      Hundred Four Thousand
      Eight Hundred Thirty-Nine Dollars ($9,804,839) less the sum of (a) Partnership
      Debt and
      (b)
      adjustments in accordance with Section
      3.3 (the
      "Purchase
      Price"). The
      Buyer
      shall pay the Purchase Price at Closing in cash, by wire transfer as directed
      by
      the Sellers, and such Purchase Price shall be allocated among the Sellers in
      the
      manner set forth on Exhibit
      B.

     

    3.2Additional
      Consideration.

     

    (a)
      Following each Reserve Determination Date, Buyer shall have prepared
and
      delivered to Sellers and Sellers shall have prepared and delivered to Buyer
      a
      Reserve Report setting
      forth the PDP Reserves and Proved Reserves in each CVR Well that is producing
      as
      of the
      Reserve Determination Date. In addition to the Purchase Price, Buyer shall
      pay
      to Sellers additional consideration for the CVR Wells ("Additional
      Consideration"), which
      additional

    

    
      
        
          
            14

          

        

        
        

      

      
        
        

        
          

        

      

      
        
        

        
          

        

      

    

     

    consideration
      shall be calculated, with respect to any Reserve Determination Date, in the
      following
      manner:

     

    (i) First,
      a
      value
      shall be determined for each CVR Well based upon

     

    the
      following formula:

     

    ((AxB)+(CxD))xB
      where

     

    A
      = the
      sum of (i) the MCFE of PDP Reserves for the CVR Well in the Reserve
      Report, and (ii) the MCFE of all production from the CVR Well since the
      Effective Time.

     

    B $3.00
      or,
      if Section
      3.2(d) applies,
      the Adjusted PDP Price.

     

    C
      = the
      MCFE
      of all Proved Reserves, other than PDP Reserves, for the CVR

     

    Well
      in
      the Reserve Report.

     

    D
      = $3.00
      or,
      if Section
      3.2(d) applies,
      the Adjusted Proved Price.

     

    E= The
      lesser of (i) .35 or (ii) the working interest, expressed as a
      percentage,

     

    retained
      by EBS in the CVR Well.

     

    (ii)
      Second,
      the
      aggregate value of all CVR Wells shall be determined by
      adding
      together all of the individual values for each CVR Well determined in
Section
      3
      .2(a)(i).

     

    (iii) Third,
      the
      cumulative Additional Consideration Offsets shall be subtracted from the value
      obtained in Section
      3.2(a)(ii); provided, however,
      that the calculations set forth in this Section
      3.2(a) shall
      be
      made in a manner such that the entire amount
      of
      deductions for Additional Consideration Offsets shall be applied solely against
      the
      Additional Consideration payments allocable to the Class A Limited Partners,
      in
accordance
      with their relative percentage ownership percentages as set forth in
Exhibit
      B, and
      payments of Additional Consideration to the Class B Limited Partners shall
      not
      be affected by Additional Consideration Offsets.

     

    (iv) Fourth,
      the
      cumulative value of Additional Consideration previously
      paid to Sellers shall be subtracted from the value obtained in Section
      3
      .2
      (a)(iii).

     

    (b)
      In
      determining the volumes of MCFE to be used in calculating the Additional
      Consideration, the average of the Proved Reserves and PDP Reserves in the
      Reserve Report
      prepared by the reserve engineer of each Party shall be utilized, provided
      that
      in no event shall
      the
      average ever exceed 125% of the Proved Reserves or PDP Reserves stated in the
      Reserve
      Report prepared by Buyer's reserve engineer. Unless otherwise approved by the
      other Party,
      Buyer shall use NSAI as their reserve engineer and Sellers shall utilize one
      of
      the reserve

    

    
      
        
          
            15

          

        

        
        

      

      
        
        

        
          

        

      

      
        
        

        
          

        

      

    

     

    engineering
      firms set forth on Exhibit
      M. All
      Reserve Reports shall be prepared in good faith utilizing reporting standards
      mandated by the SEC and each Party shall be responsible for the costs and
      expenses associated with the preparation of the Reserve Reports by their
      respective reserve
      engineers. In the event a Party fails to deliver a Reserve Report in a timely
      manner, such Reserve
      Report shall be disregarded, and the MCFE volumes in the other Party's Reserve
      Report shall
      be
      applied for purposes of this Section
      3.2.

     

    (c) The
      Additional Consideration, if any, shall be allocated among Sellers in
the
      manner set forth on Exhibit
      B (subject
      to necessary adjustments among the Sellers pursuant to Section 3.2(a)(iii)),
      and
      shall be paid to Sellers (i) within thirty (30) days following the applicable
      Reserve Report Delivery Date for any Additional Consideration paid in the form
      of WHT
      Stock
      and (ii) within ten (10) days following the applicable Reserve Report Delivery
      Date for
      any
      Additional Consideration paid in cash (in each case, referred to as an
"Additional
      Consideration Payment Date"). In
      no
      event will Buyer be required to make any payments of Additional Consideration
      prior to the Closing.

     

    (d) In
      the
      event EBS has commenced drilling of CVR Wells on or before the final
      Reserve Determination Date but it is not reasonably possible to complete a
      Reserve Report prior
      to
      the applicable Reserve Report Delivery Date, an additional Reserve Determination
      Date of
      not
      later than August 31, 2006, shall be permitted upon written request of the
      Sellers, provided,
      however,
      (i) such additional Reserve Determination Date shall be permitted only with
      respect
      to CVR Wells for which EBS has commenced drilling on or before June 30, 2006,
      and for
      which
      no Reserve Report has been delivered on or before the final Reserve Report
      Delivery Date,
      and
      (ii) any payments of Additional Consideration relating to such Reserve
      Determination Date
      shall be computed using the Adjusted PDP Price or the Adjusted Proved Price,
      as
      the case may
      be.

     

    (e)
      The
      Additional Consideration following the first two Reserve Determination
      Dates shall be comprised of sixty percent (60%) WHT Stock and forty percent
      (40%)
      cash; and after the final Reserve Determination Date, the Additional
      Consideration shall be
      comprised of a combination of WHT Stock and cash such that the total
      consideration paid to Sellers
      under this Agreement, including the Purchase Price and all Additional
      Consideration payments, shall be comprised of fifty percent (50%) WHT Stock
      and
      fifty percent (50%) cash; provided,
      however,
      Buyer may, in its sole discretion and based upon its own forecasts, adjust
      the
      ratio of WHT Stock to cash paid as Additional Consideration after any Reserve
      Determination Date as necessary to achieve a final composition of fifty percent
      (50%) WHT Stock and fifty percent (50%) cash for the total consideration paid
      to
      Seller under this Agreement.

     

    The
      number of shares of WHT Stock to be issued as Additional Consideration shall
      be
      calculated as follows:

     

    S=
      VIP

     

    where

     

    S
      =
      number of shares of WHT Stock

    

    
      
        
          
            16

          

        

        
        

      

      
        
        

        
          

        

      

      
        
        

        
          

        

      

    

    value
      of
      Additional Consideration to be comprised of WHT Stock

     

     

    P
      =  the
      average of the Closing Price of WHT Stock for the twenty (20)

     

    trading
      days following the applicable Reserve Determination Date

     

    (f) After
      the
      Closing, neither EBS nor Buyer shall have any obligation whatsoever to finance
      or otherwise contribute to the development of CVR Wells other than through
      the
      sale by EBS, through the Principals' marketing efforts, of interests in CVR
      Wells. Buyer
      shall have the option, but shall have no obligation, to fund CVR Wells subject
      to the Lease
      Bank Agreement in the manner set forth in the Lease Bank Agreement. In addition,
      Buyer shall
      have the option, but shall have no obligation, to fund twenty-five percent
      (25%)
      of CVR Wells
      not
      subject to the Lease Bank Agreement on standard partnership terms. Neither
      EBS
      nor Buyer
      shall be subject to any liability to Sellers on the basis of EBS's or Buyer's
      refusal to provide
      financing or any other support relating to the development of CVR
      Wells.

     

    (g) The
      Sellers acknowledge that from and after the Effective Time, the Principals
      shall bear sole responsibility, subject to Buyer's participation options set
      forth above, for
      securing financing for and developing, on behalf of EBS, all of the CVR Wells
      through the sale
      of
      interests in the CVR Wells to third parties. It is the Parties' intention that
      the proceeds of EBS's
      sales, through the Principals' sales efforts, of interests in CVR Wells will
      be
      sufficient to cover EBS's share of all drilling and completion costs in the
      CVR
      Wells. For each CVR Well, Westside
      will maintain a ledger comparing (i) the proceeds EBS has received, from and
      after the Effective
      Date, from the sale of interests in such CVR Well (the "CVR
      Promote Proceeds") with
      (ii)
      the
      drilling and completion costs actually paid by EBS from and after the Effective
      Date in respect of EBS's retained interest in such CVR Well (the "CVR
      Costs"), which,
      for each CVR Well,
      shall result in either an excess of CVR Promote Proceeds over CVR Costs (a
      "CVR
      Surplus")
      or
      an
      excess of CVR Costs over CVR Promote Proceeds (a "CVR
      Deficiency"). In
      the
event
      of
      a CVR Deficiency for any CVR Well, the Class A Limited Partners shall pay to
      EBS
      an amount
      equal to such CVR Deficiency, reduced by the cumulative amount of any CVR
Surpluses,
      to the extent not previously taken into account for purposes of this sentence,
      on CVR Wells
      previously completed (the "Net
      CVR Deficiency"). If
      the
      Class A Limited Partners should
      fail to pay EBS the full amount of any Net CVR Deficiency, the CVR Well in
      question will no longer constitute a CVR Well for all purposes of this
Section
      3.2.

     

    33Purchase
      Price Adiustments/Post-Closing Settlement. The
      Purchase Price

     

    shall
      be
      adjusted as follows:

    (a)The
      Purchase Price shall be adjusted upward by the following ("Sellers'
      Credits"):

     

    (1)
      the
      value of (i) all Inventory Hydrocarbons, such value to be based upon
      the
      prevailing market value for crude oil in effect as of the Effective Time
      adjusted for grade
      and
      gravity, less taxes and transportation fees deducted by the purchaser of such
      oil, such oil
      to be
      measured at the Effective Time by the operators of the Properties; and (ii)
      the
      value of all
      of
      EBS's unsold inventory of gas plant products, if any, attributable to the Leases
      at the Effective
      Time valued in the same manner as if such products had been sold;
      and

    

    
      
        
          
            17

          

        

        
        

      

      
        
        

        
          

        

      

      
        
        

        
          

        

      

    

     

    (2)
      the
      amount of any ad valorem, property, production, severance and similar
      taxes and assessments on the Properties paid by EBS after the Effective Time
      (but prior to
      the
      Closing) and attributable to the ownership of the Properties during the period
      after the Effective Time or attributable to production that occurs after the
      Effective Time.

     

    (b) The
      Purchase Price shall be adjusted downward by the following

     

    ("Buyer's
      Credits"):

     

    (1) the
      total
      sales value of all Hydrocarbons sold by EBS after the Effective
      Time, all of which are attributable to the Properties, and any other monies
      collected by EBS
      with
      respect to the ownership or operation of the Properties after the Effective
      Time, to the extent such monies are distributed or otherwise transferred by
      EBS
      to the Sellers prior to the Closing;

     

    (2) the
      amount of any ad valorem, property, production, severance and similar
      taxes and assessments on the Properties paid by EBS after the Effective Time
      and
      attributable to the ownership of the Properties during the period prior to
      the
      Effective Time or attributable to production that occurs prior to the Effective
      Time;

     

    (3)
      the
      amount of any net working capital deficit, as shown on the Financial
      Statements, excluding (A) all amounts with related parties, and (B) purchase
      price adjustment amounts taken into account in other paragraphs of this
Section
      3.2(b); and

     

    (4) the
      Allocated Value of any Casualty Loss affecting any of the

     

    Properties
      or any portion thereof.

     

    (c)
      Sellers shall prepare and deliver to Buyer, at least fifteen (15) days prior
      to
      Closing, Sellers' estimate of the adjusted Purchase Price to be paid at Closing,
      together with a preliminary statement setting forth Sellers' estimate of the
      amount of each adjustment to the Purchase Price to be made pursuant to this
      Section
      3.3. On
      or
      before Closing, Sellers and Buyer shall
      mutually prepare and agree to a closing statement substantially in the form
      set
      forth on Exhibit
      L
      evidencing the amount actually wire transferred and all adjustments to the
      Purchase Price
      taken into account at Closing, including all of the Buyer's and Sellers' Credits
      set forth in this
      Section
      3.3 (the
      "Settlement
      Statement"). The
      Settlement Statement shall be applied in determining the Purchase Price to
      be
      paid to Sellers at Closing.

     

    (d)
      Within 120 days after Closing, Buyer shall provide to Sellers, for Sellers'
      concurrence, an accounting (the "Post
      Closing Settlement Statement") of
      the
      actual amounts of Sellers'
      and Buyer's Credits for the adjustments set out in this Section 3.3. Within
      thirty (30) days
      after receipt of such statement from Buyer, Sellers shall deliver to Buyer
      a
      written report containing all of Sellers' proposed changes to such statement
      with explanations therefor, it being agreed
      that Sellers' failure to deliver such report to Buyer within such time period
      shall constitute
      acceptance by Sellers of Buyer's statement (unless failure is a result of
      Buyer's failure to
      provide necessary information or data to Sellers in a timely manner). Except
      for
      the changes raised by Sellers in their written report, no additional changes
      to
      the statement provided by Buyer shall
      be
      considered by the Parties. If Sellers have timely delivered such written report,
      the Parties shall
      then undertake to agree on the items in dispute and the adjusted Purchase Price
      no later than

    

    
      
        
          
            18

          

        

        
        

      

      
        
        

        
          

        

      

      
        
        

        
          

        

      

    

     

    thirty
      (30) days after the receipt by Buyer of the Post Closing Settlement Statement.
      The Parties shall
      attempt to resolve any disagreements on
      a
      best
      efforts basis. In
      the
      event
      such disagreements
      cannot be resolved, the matter shall be submitted to arbitration by either
      Party
      pursuant to the arbitration provisions of this Agreement. The difference between
      the final determination
      of the Purchase Price set forth on the final Post Closing Settlement Statement
      and that
      set
      forth on the Settlement Statement shall be added to or subtracted from, as
      the
      case may be,
      Additional Consideration payments following the date of such final
      determination. Buyer will
      prepare any information reasonably requested by Sellers in order for Sellers
      to
      prepare such statement
      or verify Buyer's written report. Notwithstanding any provision in this
      Agreement to the contrary, any Party may, at its own cost and expense, engage
      third party consultants for the purpose of preparing and reviewing the Post
      Closing Settlement Statement and determining the final Purchase Price
      adjustments under this Article
      III.

    TITLE
      MATTERS

     

     6.1
      Notice
      of Title Defect. Westside
      shall notify Sellers in writing as soon as reasonably
      practicable after Westside has knowledge thereof, and in any event on or before
      the final
      Reserve Determination Date, of any matter that would cause EBS's title to any
      or
      all of the Properties
      not to be Marketable Title ("Title
      Defect"), in
      each
      case together with an explanation of
      (a)
      the nature of such Title Defect, (b) the Properties (or portions thereof)
      affected thereby, and
      (c)
      Westside's proposed Defect Value (as hereinafter defined) for such Title Defect.
      Any matters that would otherwise constitute Title Defects but which are not
      specifically raised in writing
      (with the explanation as contemplated in the immediately preceding sentence)
      by
Westside
      prior to the final Additional Consideration Payment Date shall conclusively
      be
      deemed waived
      by
      Westside.

    6.2Remedies
      for Title Defects.

     

     

    (a) Buyer
      shall be entitled to an Additional Consideration Offset for any Title
Defects
      at any time on or before the final Additional Consideration Payment Date. A
      notice requesting
      an Additional Consideration Offset for Title Defects must be timely and in
      writing and include appropriate documentation to substantiate the adjustment,
      or
      Buyer will be deemed to
      have
      waived its claim to such offset.

     

    (b) If
      Buyer
      gives notice under the previous section, the Parties will meet and use
      their
      best efforts to agree on the validity of the claim and, if applicable, the
      amount of the adjustment (the "Defect
      Value"), using
      the
      following criteria:

     

    (1)
      If
      the claim is based on EBS owning a different net revenue interest in
a
      Property than that shown on Exhibit
      D with
      respect to such Property, then the
      adjustment will be the absolute value of the number determined by the following
      formula:

     

    Adjustment
      = A x (1-[B/C])

     

    A
      =
      Allocated Value for the affected interest

     

    B
      =
      Correct net revenue interest for the affected interest

     

    C
      = Net
      revenue interest for the affected interest as shown on Exhibit
      D

     

    (2)
      If
      the claim is based on any other obligation or burden, the adjustment
will
      be
      the sum necessary to compensate Buyer for the adverse economic effect
      on
      the affected Property.

     

    (c) If
      the
      Defect Value cannot be determined based on the above criteria, and if
      the
      Parties cannot otherwise agree on the Defect Value or the Parties are unable
      to
      agree upon whether
      a
      Title Defect exists, subject to the provisions of Article
      6.2(d) below,
      the Parties may elect to resolve the dispute under the arbitration provisions
      in
      this Agreement.

     

    (d) No
      Additional Consideration Offset for Title Defects shall be made unless
and
      until
      the aggregate value of all Title Defects (herein called the "Aggregate
      Title Defect Value") exceeds
      a
      threshold of One Hundred Thousand Dollars ($100,000.00) and once the threshold
      is exceeded, all Defect Values shall be considered in applying this Article
      VI. Defect
      Values
      with an agreed individual value of less than Ten Thousand Dollars ($10,000.00)
      shall not be
      included in the calculation of the Aggregate Title Defect Value. For purposes
      of
      this section, the
      cost
      to cure a Title Defect shall not be considered in determining Aggregate Title
      Defect Value.

     

    (e)
      Sellers may, at their sole option, notify Westside at any time within ten
(10)
      business days after receiving notice from Buyer of a Title Defect that they
      elect to cure some
      or
      all of such Title Defects. No Additional Consideration Offset will be applied
      for Title Defects
      that Sellers cure. If any Title Defect is not cured within thirty (30) days
      after Sellers so

      Westside of their intention to cure, an Additional Consideration Offset will
      be
      applied as described in Section
      3.2.

      warranty or covenant herein set forth, or (2) the ownership of EBS after the

      EBS
      and the Buyer Group harmless from and against any and all Losses arising out

      Indemnification
      Procedures. In
      the
      event that any claim for which a Party providing
      indemnification (the "Indemnifying
      Party") would
      be
      liable to the other Party (the "Indemnified
      Party") is
      asserted against or sought to be collected by any third person, the Indemnified
      Party shall promptly notify the Indemnifying Party of such claim, specifying
      the
      nature of such claim and the amount of the estimated amount thereof to the
      extent then feasible (which

      Claim
      Notice (the "Indemnity

      Indemnified Party hereunder with respect to such claim, and (ii) if it
does
      not
      dispute such liability, whether or not it desires, at its sole cost and expense,
      to defend the
      Indemnified Party against such claim; provided however, that the Indemnified
      Party is hereby authorized
      prior to and during the Indemnity Notice Period to file any motion, answer
      or
      other pleading, submission or document which it shall deem necessary or
      appropriate to protect its interests. In the event that the Indemnifying Party
      notifies the Indemnified Party within the Indemnity

      manner as to avoid any risk of the Indemnified Party becoming subject to

      such claim, and
      the
      amount of any resulting Losses (including, without limitation, court costs
      and
      attorneys' fees)
      incurred by the Indemnified Party in connection with such defense, shall be
      conclusively deemed to be the liability of the Indemnifying Party
      hereunder.

     

    9.4
      Buyer's
      Sole Remedy. Buyer's
      sole remedy in the event of a Seller Indemnified Loss
      shall be recovery of any such Losses by way of an Additional Consideration
      Offset, except where
      such Seller Indemnified Loss is the result of gross negligence, fraud, or
      willful neglect on the
      part
      of any Seller.

     

    9.5
      Survival
      of Indemnity. Each
      Party's indemnity obligations under this Agreement shall
      survive the Closing and shall terminate upon the Final Additional Consideration
      Payment Date.

    Section
      2.1 The
      Loans.The
      Initial Loan and CVR Loans. Borrowers
      desire to borrow funds
      to
      (i) fund certain initial drilling operations described on Schedule
      2.1
      (the
      "Initial
      Development
      Operations") and
      (ii)
      to reimburse Parent for certain drilling costs and other capital projects
      related to the Properties described on Schedule
      2.1
      (the
      "Reimbursed
      Costs"). Borrowers
      also desire to borrow funds to be reimbursed for certain expenses incurred
      (including accounting,
      legal and other similar fees) or obtain advances to pay certain (i) expenses
      incurred by
      Borrowers in connection with preparation, execution, due diligence and the
      closing of the PSAs
      and
      relating to land and title work, and environmental assessment and review in
      connection
      with the Properties, (ii) expenses incurred by Borrowers and by Lender under
      Section
      7.1(z)
      and
      (iii)
      relating to filing fees which may be required to properly file any and all
      Security Documents
      (collectively, the "Closing
      Costs"). In
      addition to the Closing Costs, Borrowers have agreed
      to
      pay Lender an initial Facility Fee pursuant to Section
      71(bb). The
      aggregate amount of
      the
      advances under this Section
      2.1(a) shall
      be
      equal to $5,355,000 and shall consist of (1) the advance
      to fund the Initial Development Operations and the Reimbursed Cots in an amount
      of $5,100,000,
      (2) the payment of expenses to Lender in an amount of $85,000 (3) the payment
      for additional
      Closing Costs in an amount of $60,000, (4) the payment .for the Facility Fee
      in
      the aggregate
      amount of $105,000 and (5) the payment of the Administration Fee in the Amount
      of $5,000
      (collectively, the "Initial
      Loan"). Subject
      to the terms and conditions hereunder, Lender agrees to advance the Initial
      Loan
      to Borrowers and agrees to wire transfer the amount of the Initial Loan, less
      the initial Facility Fee, to the designated payees noted in the Wire Transfer
      Instructions on the Closing Date. Borrowers irrevocably authorize Lender to
      transfer the initial Facility Fee to Lender's account and the initial Facility
      Fee shall be deemed advanced by Lender to Borrowers and paid by Borrowers to
      Lender contemporaneously with Closing.

     

    On
      or
      before the 10th
      day
      following the last Reserve Report Delivery Date and so long
      as
      no Unmatured Event of Default or Event of Default shall have occurred and
      be

    continuing,
      Borrowers may request additional advances up to an aggregate amount of
$7,500,000

      3.2
      of
      the
EBS
      Production
      PSA (after applying any amounts described in item (a) (i.e.,
      adjustments for title defects) of the definition of "Additional Consideration
      Offsets" in
      the
      EBS Production PSA, but without regard to the application of any other
      Additional Consideration
      Offsets), for the CVR Wells ("CVR
      Loans"). To
      request a CVR Loan, Borrowers
      shall provide Lender a Request for Commitment at least five (5) Business
Days
      prior to the date of the requested CVR Loan specifying therein the CVR Well(s)
      for which
      CVR
      Loan(s) are being requested by Borrowers, and Borrowers shall certify
therein
      that all conditions and terms set forth in the EBS Production PSA in relation
      to
such
      CVR
      Wells have been satisfied. Each Request for Commitment in relation to CVR
Loans
      shall also include the applicable request for an advance of the additional
      Facility Fee
      pursuant to Section
      7.1(bb). Subject
      to the foregoing, Lender shall advance the CVR Loans to Borrowers on the
      requested date.

     

    (a)Development
      Loans.

     

    (i) Prior
      to
      the Drawdown Termination Date, Lender may, but shall not
      be
      obligated to, make additional advances to Borrowers of the Development Loan(s)
      to be used exclusively for certain Development Operations such that the
total
      of
      such additional Development Loan advances under this Section
      2.1(b) plus
      the
      aggregate advances otherwise made pursuant to this Agreement (including
      but limited to Overhead Advances and advances to pay the Facility Fee
and,
      to
      the extent permitted under this Agreement, advances to pay Corporate Income
      Taxes) will not exceed the Maximum Loan Amount. Any Request for Commitment
      for a Development Loan in relation to a Development Operation shall
      be
      for a minimum of $1,000,000 (except in relation to the Committed Development
      Loan described below) and will be subject to Lender's approval in its
      sole
      and absolute discretion. Each Request for Commitment shall also include
(1)
      the
      applicable request for an advance of the additional Facility Fee payable
      pursuant to Section
      7.1(bb) and
      (2) a
      variance allowance not to exceed ten percent (10%)
      of
      the estimated expenses set forth in the Request for Commitment and supporting
      materials for each Development Operation (such allowance will be available
      only to the extent the actual costs of any Development Operation exceeds
      100% of the estimated costs). Notwithstanding the foregoing, Borrowers are
      hereby deemed to have provided the requisite Request for Commitment to
Lender
      for $5,000,000 of the Development Loans (the "Committed
      Development Loan")
      for
      certain Development Operations as more particularly described on Schedule
      2.1(b)(i) plus
      the
      applicable Facility Fee. Lender is hereby deemed to have
      committed to make such Committed Development Loan no later than March
15,
      2007,
      subject, however, to the satisfaction of all of the conditions set forth
herein.
      The Development Operations described on Schedule
      2.1(b)(i) that
      are
ultimately
      conducted with proceeds of the Committed Development Loan shall be subject
      to mutual agreement between Lender and Borrowers.

     

    (ii) Within
      ten (10) days after the receipt from Borrowers prior to the Drawdown
      Tetntination Date of a Request for Commitment listing all
      applicable

    

    
      
        
          
            921350_11

          

        

         

      

      
         

        
          

        

      

      
         

        
        

      

    

    expenditures
      that Borrowers desire to make to conduct a Development Operation, Lender
      shall notify Borrowers in writing whether in its sole and absolute discretion
      Lender will make an advance equal to the total estimated expenditures shown
      on
      such Request for Commitment. If Lender does not agree to make an advance as
      requested in any such Request for Commitment covering any Development
      Operation, Borrowers' participation in the proposed Development Operation
      identified in the applicable Request for Commitment cannot, by itself,
be
      urged
      as the basis of an Unmatured Event of Default or Event of Default; provided
      that
      Borrowers' compliance with the terms and conditions of this Agreement
      will at all times be evaluated in the context of its ownership and operation
      of all of the Properties, without regard to whether Lender has made an
advance
      with respect to a Development Operation on a particular Property. If
Lender
      agrees to make any such advance for a Development Operation, then Borrowers
      may participate in the Development Operation proposed in their Request
      for Commitment, and Lender shall advance the funds necessary to pay Borrowers'
      share of the costs and expenses attributable to such proposed operations
      (not to exceed the amount requested in the Request for Commitment). Any
      advances to be made by Lender under this Section
      2.1(b), if
      at
      all, shall be made
      within five (5) Business Days after receipt from Borrowers of a cost certificate
      in the form attached hereto as Exhibit
      "E" (the
      "Cost
      Certificate"), duly
      executed by an authorized officer of Borrowers, certifying the amount of
costs
      and
      expenses incurred and to be incurred by Borrowers in connection with
such
      approved Development Operation, together with the supporting documentation
      referred in the form of Cost Certificate, including, without limitation,
      the applicable AFE(s).

     

    (iii)
      Any
      Request for Commitment shall be made by Borrowers for business
      opportunities, projects, and/or uses that are described as Development
      Operations subject, without limitation, to the following:

     

    (1) All
      statements of costs and estimates provided to Lender shall
      be
      rendered in sufficient detail to give Lender complete and accurate information
      as to the purpose for and amount of all items included therein, and
      Lender shall be entitled to such additional information regarding such
expenditures
      as Lender may reasonably request. All such data shall be subject
      to audit by Lender's representatives at any time mutually agreeable to the
      parties.

     

    (2) Borrowers
      agree that, subject to any other conditions expressly
      set forth in this Agreement, with respect to any Development Operation
      consisting of a new-well drill or any other operation requiring Borrowers
      to expend more than $100,000, Lender's funding of such operation is further
      subject to the requirement that prior to or contemporaneously
      with the submission of a Request for Commitment covering
      each such operation Borrowers shall submit to Lender a then-current
      Title Opinion relating to the Leases covering the lands relating to such
      operations, unless a current Title Opinion covering such lands has

    

    
      
        
          
            921350_11

          

        

         

      

      
         

        
          

        

      

      
         

        
        

      

    

    already
      been provided hereunder following Closing, which confirms that Borrowers
      own Defensible Title thereto subject only to a first priority lien under the
      Deed of Trust in favor of Lender and Permitted Encumbrances.

     

    (3)
      Notwithstanding the foregoing or anything herein to the contrary,
      in no event shall Lender be obligated to make any Development Loans, including
      the Committed Development Loan, pursuant to this Section
      2.1(b) such
      that
      the aggregate advances made under this Agreement
      exceed the Maximum Loan Amount (less the aggregate amount
      of
      Facility Fees) for all combined Development Operations approved
      by Lender.

     

    (iv) No
      Unmatured Event of Default or Event of Default shall have occurred
      and be continuing and no Loan shall be advanced following the Drawdown
      Temiination Date.

     

    (v) Notwithstanding
      the thin's
      of this
Section
      2.1(b) and
      the
      definition of
      "Development Loans," to the extent no Event of Default has occurred and is
      continuing
      and the distributions to Parent pursuant to Section
      2.6(c) plus
      available Overhead
      Advances are insufficient to pay the current Corporate Income Taxes, Borrowers
      may, from time to time, submit a Request for Commitment for a Development
      Loan to be used by Parent for payment of the Corporate Income Taxes.
      Such Request for Commitment shall provide Lender all inforniation regarding
      the amount of Corporate Income Taxes due and payable and the date of
the
      requested Development Loan which may not be earlier than 20 days after
receipt
      of Request for Commitment by Lender; provided that Development Loans
for
      payment of Corporate Income Taxes, plus the applicable Facility Fee, shall
      be
the
      lesser of (i) the amount of tax payments generated on any amount paid in
principal
      (to be calculated by multiplying the aggregate amount of principal paid
by
      the
      current tax rate less any prior advances made to pay Corporate Income
Taxes),
      or (ii) an aggregate amount of $2,000,000 during any calendar year, but in
      no
      event
      an amount that would increase the total aggregate amount advanced above
      the
      $45,000,000 facility size.

     

    (b)
      Overhead
      Advances. Prior
      to
      the Drawdown Termination Date and if no Unmatured
      Event of Default or Event of Default exists, Lender will, from time to time,
      make
      certain advances to the Borrowers that constitute Loan proceeds hereunder
("Overhead
      Advances"), which
      may
      not, in the aggregate exceed $1,500,000. Each Overhead
      Advance shall be advanced by Lender contemporaneously with the distribution
      of
      Net
      Revenue pursuant to Section
      2.6(c); provided,
      however, that
      the
      application of the amount
      described in Section
      2.6(b) to
      be
      applied to Debt Service must be sufficient to pay
      all
      interest that is due and payable for all the outstanding Loans for an
      Overhead

    Advance
      to be available. The Overhead Advances will be in amounts required in
addition
      to the amount of Net Revenue paid to Borrowers under Section
      2.6(c), such
      that
the
      Net
      Revenue disbursed to Borrowers under Section
      2.6(c) together
      with such Overhead
      Advance will equal (but will not exceed) $250,000 per month. In lieu of using
      such
      amounts to pay Overhead Expenses, however, Borrowers may request that the
      aggregate amount available for Overhead Advances (and not otherwise advanced

by
      Lender
      in its sole discretion. In each such case, Borrowers shall provide Lender
sufficient
      information, acceptable to Lender, detailing the use of Overhead Advances.
      No
      Facility Fee will be payable in connection with the making of any Overhead
      Advance used to pay Overhead Expenses.

      Promissory
      Note. The
      Loans
      described in Section
      2.1 and
      all
      other amounts
      due under this Agreement shall be evidenced by a promissory note (the
"Note")
      issued
      by
      Borrowers to Lender in the face amount of $45,000,000, in the form of
Exhibit
      "B," appropriately
      completed. The final maturity date of such Note shall be the Loan Termination
      Date and all amounts evidenced by the Note shall be secured by the Security
      Documents.

     

    Section
      2.2Interest.

     

    (a) Subject
      to the provisions of subsection (b) below, each Loan shall bear interest
      on the outstanding principal amount thereof at a rate per annum equal to the
      Interest
      Rate and shall be payable as set forth in Section
      2.6 hereof.

     

    (b) If
      any
      amount payable by Borrowers (other than interest) under any Loan Document
      is not paid when due (without regard to any applicable grace periods), whether
      at
      stated
      maturity by acceleration or otherwise, such amount shall thereafter bear
      interest at the Default Rate to the fullest extent permitted by applicable
      laws.
      Furthermore, while any
      Event
      of Default exists (either before or after acceleration), Borrowers shall pay
      interest
      on the principal amount of all outstanding Obligations at the Default Rate
      to
      the fullest extent permitted by applicable laws.

     

    (c) Interest
      on each Loan shall be due and payable in arrears on each Repayment
      Date applicable thereto and at such other times as may be specified herein.
      Interest
      hereunder shall be due and payable in accordance with the terms hereof before
      and
      after
      judgment, and before and after the commencement of any proceeding under any
      applicable
      bankruptcy, insolvency or other similar law of any jurisdiction now or
hereafter
      in effect, including the federal Bankruptcy Code, as amended from time to time.
      Interest
      which has accrued and is not paid when due shall be added to and become part
      of
the
      principal under the Note; provided,
      however, the
      capitalization of such accrued and unpaid interest pursuant to this sentence
      will not preclude Lender from declaring or maintaining
      an Event of Default based on Borrowers' failure to pay such amount to the
extent
      Lender has such right under any other provision of this Agreement or under
      any
      of the other Loan Documents.

     

    (d) All
      computations of interest and all fees shall be made on the basis of a
year
      of
      360 days and the actual number of days elapsed. Interest shall accrue on the
      day
on
      which
      the Loan is made, but shall not accrue on the day on which the Loan or such
      portion
      thereof is paid, provided that any Loan that is repaid on the same day on which
      it is
      made
      shall bear interest for one day.

      Interest Period), the percent of Net Revenue swept and applied by Lender shall
      automatically
      be increased to a percentage (up to 100% if necessary) necessary to sweep
a
      sufficient portion of the Net Revenue to pay (i) all Debt Service and other
      Obligations due
      for

      that
      Borrowers shall provide Lender at least three (3) Business Days' prior
written
      notice thereof, except in connection with Section
      2.4(b).

      disposition of Collateral, any insurance proceeds or the net proceeds from
      the
issuance
      of any equity of any Borrower on the Business Day following such Borrower's
      receipt of such proceeds, unless such proceeds are used with the prior written

      to
      promptly acquire replacement assets which are contemporaneously subjected to
      a
      first
      priority Lien in favor of Lender and otherwise on terms satisfactory to
      Lender.

     

    (b) Prepayments

     Section
      2.6 Application
      of Receipts.
      Net
      Revenue
      shall be calculated by Lender based
      on
      the Property Operating Statement. Borrowers shall prepare and deliver the
      Property Operating
      Statement to Lender no later than the last Business Day of each month. Such
      Property Operating
      Statement shall detail Borrowers' Gross Receipts and Expenses with respect
      to
      the month
      in
      which such Property Operating Statement is scheduled to be delivered and for
      any
other
      such amounts relating to any preceding months that were not previously accounted
      for in a Property
      Operating Statement. The first Property Operating Statement shall be delivered
      on April
      30,
      2006; provided,
      however, that
      this
      first Property Operating Statement shall cover the period
      from Closing through and including such date. On the Repayment Date at the
      end
      of each Interest
      Period, Gross Receipts for such Interest Period shall be applied as
      follows:

     

    (a) First,
      to
      the amount necessary to pay the Expenses.

     

    (b) Second,

      that,
      upon the occurrence and continuation of an Event of Default and to the extent
      required by Section
      2.2(e)
      above,
      the percentage of the Net Revenue to be applied for Debt Service and other
      Obligations
      to Lender shall be increased to one hundred percent (100%) or such other amount
      specified in Section
      2.2(e)
      above.
      The amount paid to Lender pursuant to this subpart
      (b) shall be applied first to any interest due on the Note, until all accrued
      interest is
      paid
      in full, and any remaining amounts paid pursuant to this subpart (b) shall
      be
applied
      to remaining outstanding principal under the Note.

     

    (c)
      Third, so long as no Event of Default shall have occurred and be continuing,
      any remaining amounts shall be paid to Borrowers by remitting such sums to
      the
      Borrower Operating Account in accordance with Section
      2.7(b)

     

    Section
      2.7 Borrower
      Sub-Account.Until all
      of
      Borrowers' Obligations have been fully
      satisfied, Borrowers shall direct and cause all Purchasers of Hydrocarbons,
      Pipeline Parties, the
      Operator, all account debtors of Borrowers, and any other customers of Borrowers
      to deposit all
      payments of any nature whatsoever due and owing by such Persons to Borrowers
      directly into an
      account maintained by Lender (the "Lender
      Account"); provided,
      however, that
      Purchasers of Hydrocarbons
      may make distributions to royalty interest owners and third-party working
      interest owners
      and may withhold Severance Taxes. Lender shall establish a sub-account (the
      "Borrower
      Sub-Account")
      on
      its
      internal books and records and shall credit to such Borrower Sub-Account all
      collected funds which constitute payments referred to in the preceding sentence.
      Borrowers authorize
      Lender to debit the Borrower Sub-Account for the payment of all Obligations
      hereunder
      when due and payable.

     

    (a)
      On
      each Repayment Date, provided
      that
      no
      Unmatured Event of Default or
      Event
      of Default has occurred and is continuing, and after satisfying all
      distributions to Lender
      pursuant to Section
      2.6(b), Lender
      will release to Borrowers the funds credited to the
      Borrower Sub-Account, by remitting such amounts to the Borrower Operating
Account,
      in order to pay (i) the Expenses which have been incurred and are due and
payable
      and which are referenced in the most recent Property Operating Statement
delivered
      to Lender and (ii) the amount payable to Borrowers pursuant to Section
      2.6(c), (iii)
      together with any Overhead Advances, if applicable (the "Net
      Revenue Reimbursement Amount"). Borrowers
      will have one hundred eighty (180) days after the receipt of such funds to
      contest the amounts of funds released, after which time the amounts released
      will be deemed conclusively correct absent manifest error, provided Borrowers
      may not contest any such amounts released for any reason after two hundred
      seventy (270) days after the receipt of such funds or after the Loan Termination
      Date. Borrowers
      shall be permitted, with prior reasonable notice and during Lender's normal
      business
      hours, to review at Lender's offices any documents in which specific references
      to
      and
      the calculation of the Net Revenue Reimbursement Amount distributed during
      the
ninety
      (90) day period preceding such review are made.

     

    Any
      amounts deposited into the Lender Account owing to third-party working interest,
      overriding
      royalty interest and royalty interest holders whose interests in the Properties
      were created
      prior to the time such Properties became subject to any of the Security
      Documents or to taxing
      authorities for production taxes shall be released by Lender to Borrowers within
      two (2) Business

    to
      be
      paid so that Borrowers may return such amounts to such third-party working
      interest, overriding royalty interest and royalty interest holders and taxing
      authorities. Lender shall have the right to undertake audit procedures during
      normal business hours and upon reasonable prior notice
      to
      periodically confirm that such payments have been made by Borrowers. Lender
      shall have
      the
      right at its option, but not the obligation, to make such payments directly
      to
      the third-party
      working interest, overriding royalty interest and royalty interest holders
      and
      taxing authorities
      upon the occurrence of and during the continuance of an Event of Default or
      an
Unmatured
      Event of Default hereunder. Except as provided in this paragraph, upon the
      occurrence
      of and during the continuance of an Event of Default, any funds in the Borrower
      Sub-Account
      may be applied, at Lender's option, against all unpaid Obligations. Lender
      agrees to
      maintain accounting records with respect
      to
      the
      Borrower Sub-Account and make such records available
      to Borrowers upon reasonable request.

     

    Section
      2.8 Use
      of Proceeds. Initial
      Loan and CVR Loan proceeds may be used by Borrowers
      for the purposes described in Section
      2.1(a). Development
      Loan proceeds may be used
      by
      Borrowers for the purposes of funding Borrowers' share of costs and expenses
      relating to
      the
      conduct of the Development Operations pursuant to Section
      2.1(b) and
      approved by Lender
      in
      writing. Overhead Advances may be used only for purposes and only for the period
      specified
      in Section
      2.1(c). In
      no
      event shall funds from the Loans be used by Borrowers, directly or indirectly,
      for personal, family, household or agricultural purposes, or any other
purpose
      not specifically described in this Section
      2.8.

     

    Section
      2.9 Initial
      Swap Agreement. At
      or

      thereunder
      that in the aggregate subject not more than ninety percent (90%) of the notional
      volume
      of
      Borrowers' Net Revenue Interest share of Proved Developed Producing Reserves
      scheduled
      to be produced for the period commencing on the date of such initial Permitted
      Swap Agreement
      through and including December 31, 2007 (based on the Reserve Report(s)
      evaluated by
      Lender

      Loan
      Document shall be made free and clear of and without deduction for any and
      all
taxes,

      of
net
      income taxes), by the jurisdiction (or any political subdivision thereof) under

Lender
      the original or a certified copy of a receipt evidencing payment thereof. To
      the
      extent Borrowers pay any such Taxes on behalf of Lender to a taxing authority
      and any such
      taxing authority refunds any such Taxes during the term of this Agreement to
      Lender,
      Lender shall return any such amounts to Borrowers.

     Section
      3.2 Inability
      to Determine LIBOR Rate. If
      Lender
      determines in connection
      with any request for a Loan or continuation thereof for any reason that adequate
      and reasonable means do not exist for determining the LIBOR Rate, Lender will
      promptly so notify Borrowers
      if Lender reasonably determines that such event or events have any impact on
      the
application
      of the Interest Rate. In such event, Lender shall use, as the LIBOR Rate, the
      average LIBOR
      Rate for the two immediately preceding months (for one-month teiins) until
      Lender notifies Borrowers that the circumstances giving rise to such
      determination no longer exist.

Agreements)
      relating to the Working Interests and/or Net Revenue Interests in the Properties
      and relating
      to Permitted Swap Agreements will receive notification from Lender (as assignee)
      and Borrowers, in form and substance satisfactory to Lender, of the assignment
      into the Lockbox or directly
      into the Lender Account of all proceeds (the "Notice
      of Assignment of Proceeds") from
      sales
      of
      all production from or allocable to Borrowers' Net Revenue Interests in the
      Properties and
      all
      other Gross Receipts into the Lockbox or directly into the Lender Account

      use
      commercially reasonable efforts to obtain and deliver, within thirty (30) days
      after the Closing Date, from all Purchasers of Hydrocarbons, Pipeline Parties

      from
      selling any Hydrocarbon production
      to a Purchaser that refuses to execute and deliver to Lender a Notice of
      Assignment of
      Proceeds. If Borrower receives any Gross Receipts, Borrowers shall promptly
      notify Lender and
      follow Lender's instructions regarding submitting such proceeds to the Lockbox
      or the Lender

      gas pricing used will be determined by Lender based on eighty-five percent
      (85%)

      Lender's sole discretion,
      (A) the historical average basis differential between the pricing employed
      by independent third-party over-the-counter counterparties compared to
the
      prevailing wellhead prices at the production location and (B) any other
      adjustments as may be necessary including but not limited to gathering,
      transportation, and processing fees, and further adjusted to reflect the
      economic effect of transactions under any Permitted Swap Agreement.

     

    (ii) Average
      lease operating expenses and production taxes will be derived by the Engineer(s)
      who prepare such report from the Operator's best estimate

      to
      Lender's approval (which shall not be unreasonably withheld).

     

    (f) Notice
      of Investigations or Proceedings. Borrowers

            921350_11

          

        

         

      

      
         

        
          

        

      

      
         

        
        

      

    

    pursuant
      to a Permitted Swap Agreement in form and substance reasonably satisfactory
      to
Lender,
      such that up to but not more than ninety percent (90%) of the volume of
Borrowers'
      Net Revenue Interest share of the Proved Developed Producing Reserves scheduled
      to be produced during the term of this Agreement, but not beyond the Loan
Termination
      Date (based upon the most recent Reserve Report) and in an amount not to
exceed
      the sum of (i) the outstanding Obligations plus
      (ii) any
      undrawn availability under this
      Agreement plus
      (iii) the
      total
      availability under the Permitted Swap Agreement, are dedicated
      to the Permitted Swap Agreements or such other price risk management
program
      as approved by Lender; provided,
      however, if
      projected Net Revenue is insufficient to fully amortize the Loans by their
      stated maturity, as more particularly described
      in Section
      10.1(h)(i), Lender
      may require that Borrowers enter into one or more
      such
      swaps for a term or terms that extend beyond the Loan Termination Date.
      Borrowers and Lender shall endeavor to agree upon a swap strategy that will
      most
accurately
      reflect the make-up and pricing of the Hydrocarbons produced and sold by
Borrowers,
      but if the parties are unable to agree on the swap strategy, Borrowers shall
      not
be
      released from their obligation to implement the Permitted Swap Agreement(s)
      required
      by this Section
      7.1(x).

      environmental, engineering,
      technical, travel, legal and related expenses incurred by Lender in connection
      with the Credit Agreement and the Loan Documents and the transactions
contemplated
      thereunder (to be financed by Lender as a portion of the Initial Loan) up to
      a
      maximum
      of $85,000, and, thereafter, reimburse Lender for all such expenses incurred
      in
      connection therewith, including, without limitation, any subsequent amendment,

      (i)
      remedy all material matters set forth in the Environmental Report and any
environmental
      compliance issues listed on Schedule
      4.1(s) so
      as to
      be in compliance in all
      material respects with all applicable Environmental Laws and (ii) provide all
      relevant information
      to Lender in relation thereto.

     

    (bb)
      Facility
      Fee. The
      Facility Fee in relation to the Initial Fee shall be earned and
      payable by Borrowers to Lender out of the Initial Loan advances evidenced by

      Loan in the amount of the Facility Fee will be deemed to have been advanced
      by
Lender
      to
      Borrowers on the Closing Date, with such Facility Fee having been deemed
      contemporaneously paid by Borrowers to Lender. Each time Lender advances a

            921350_11

          

        

         

      

      
         

        
          

        

      

      
         

        
        

      

    

    (other
      than the Initial Loan), a Loan in the amount of an additional Facility Fee
      will
      be earned
      and Borrowers shall be deemed to have requested that Lender advance to
Borrowers
      such additional Facility Fee on such date, with such additional Facility Fee
      having been contemporaneously paid by Borrowers to Lender.

     

     (cc)
      Development

      2.1(b), Borrowers
      shall conduct all such Development Operations in accordance with and within
      the
      cost and time parameters specified in the Request for Commitment specific to
      those Development Operations; provided
      that
      Lender is not obligated to commit funds for Development Operations except
      as
      specifically described in
      Section
      2.1(b) for
      any
      specific Development Operations,
      including any associated cost overruns; and provided
      further that
      if
Borrowers
      are unable to conduct all such Development Operations within the amounts funded
      as the Development Loans described in the specified Request for Commitment,
      Borrowers shall use their own capital to conduct and complete all such
      Development

    Operations.
      Borrowers' intent, willingness and ability to conduct each of the Development
      Operations and the actual implementation of such Development Operations
is
      a
      material inducement to Lender's entry into this Agreement, in the absence of
      which Lender
      would not have done so. Time is of the essence in the proposal and conduct
      by
      Borrowers of each of the Development Operations approved by Lender.

     

    (dd)
      Protection
      Against Drainage. Until

      Borrowers
      shall act as a prudent operator in an effort to identify and prevent the
occurrence
      of any drainage of Hydrocarbons from the Properties and (ii) to the extent
      that
Properties
      are not operated by Borrowers, Borrowers shall utilize their property and

      Lender pursuant to the provisions of this Agreement which are not paid on or
      before
      the Closing Date in accordance with Section
      7.1(z)
      shall be payable within fifteen (15) days after Borrowers' receipt of an invoice
      therefor from either Lender or its third-party

    FURTHER
      RIGHTS OF LENDER

     

     Section
      8.1 Maintenance
      of Security Interests. Borrowers
      authorize Lender to execute alone any financing statement or other documents
      or
      instruments that Lender may require
      under Section
      6.2 to
      perfect, protect or establish any Lien hereunder or under any Security
      Documents and further authorizes Lender, upon notice to Borrowers, to sign
      Borrowers' names
      on
      the same. Borrowers hereby authorize Lender, during the continuance of any
      Event
      of Default,
      to appoint such Person or Persons as Lender may designate as its agent and
      attorney-in-fact
      to endorse the name of any Borrower on any checks, notes, drafts or other forms
      of
      payment or security that may come into the possession of either Lender or any
      Affiliate of Lender,
      to sign any Borrower's name on invoices or bills of lading, drafts against
      customers, notices of assignment, verifications and schedules and, generally,

      do all things necessary to carry
      out
      this Agreement and the Security Documents. The powers granted herein, being
      coupled
      with an interest, are irrevocable. Neither Lender nor the agent and
      attorney-in-fact shall be liable for any act or omission, error in judgment
      or
      mistake of law so long as the same is not malicious
      or grossly negligent. Upon payment and performance of all Obligations of
      Borrowers to
      Lender, such power of attorney will become null and void.

     

     Section

      of Obligations. In
      the
      event that Borrowers fail to purchase or
      maintain insurance in accordance with the requirements of this Agreement, or
      to
      pay any tax, assessment,
      government charge or levy, except as the same may be otherwise permitted
hereunder,
      or in the event that any Lien prohibited hereby shall not be paid in full or
      discharged, or
      in the
      event that Borrowers shall fail to perform or comply with any other covenant,
      promise or
      Obligation to Lender hereunder or under any Loan Document, Lender may, but
      shall
      not be required
      to, perform, pay, satisfy, discharge or bond the same for the account of
      Borrowers, and all
      monies so paid by Lender, including, without limitation, reasonable attorneys'
      fees and disbursements,
      shall be treated as an additional Obligation of Borrowers to Lender hereunder

      charge, rent or
      payment therefor, or place custodians in control thereof, remain on such
      premises and use the same
      and

      at
      any time after the date of this Agreement,
      any Affiliate of either Borrower proposes to drill any new Well(s) on an

such
      Affiliate-Owned Barnett Interest—Borrowers shall promptly prepare and submit to
      Lender a Request for Commitment requesting a Development Loan advance to

      or equitable
      right, remedy, or claim under or with respect to this Agreement or any provision
      of this Agreement.
      This Agreement and all of its provisions and conditions are for the sole and

    Section
      11.5 Governing
      Law; Submission to Process. Except
      to
      the extent that the law
      of
      another jurisdiction is expressly elected in a Loan Document, the Loan Documents
      shall be
      deemed
      contracts and instruments made under the laws of the State of Texas and shall
      be
construed
      and enforced in accordance with and governed by the laws of the State of Texas,
      without
      regard to principles of conflicts of law. This Agreement has been entered into
      in Houston,
      Texas and shall be performable for all purposes in Harris County, Texas. Subject
      to the provisions of Article
      XII, courts
      within the State of Texas shall have jurisdiction over any and all disputes
      between any Borrower and Lender, whether in law or equity, including, but not
      limited to,
      any
      and all disputes arising out of or relating to this Agreement or any other
      Loan
      Document; and
      venue
      in any such dispute whether in federal or state court shall be laid in Harris
      County, Texas.

     

    Section
      11.6 Limitation
      on Interest. Lender,
      Borrowers and any other parties to any Loan
      Documents intend to contract in strict compliance with applicable usury law
      from
      time to time in effect. In furtherance thereof, the parties stipulate and agree
      that none of the terms and provisions contained in the Loan Documents shall
      ever
      be construed to create a contract to pay, for
      the
      use, forbearance or detention of money, interest in excess of the maximum amount
      of interest
      permitted to be charged by applicable law from time to time in effect. No
      Borrower nor any
      present or future guarantors, endorsers or other Persons hereafter becoming
      liable for payment
      of any Obligation shall ever be liable for unearned interest thereon or shall
      ever be required
      to pay interest thereon in excess of the maximum amount that may be lawfully
      charged under applicable law from time to time in effect, and the provisions
      of
      this Section
      11.6 shall
      control
      over all other provisions of the Loan Documents which may be in conflict or
      apparent conflict
      herewith. Lender expressly disavows any intention to charge or collect excessive
      unearned
      interest or finance charges in the event the maturity of any Obligation is
      accelerated. If (a) the maturity of any Obligation is accelerated for any
      reason, (b) any Obligation is prepaid and as
      a
      result any amounts held to constitute interest are determined to be in excess
      of
      the legal maximum,
      or (c) Lender or any other holder of any or all of the Obligations shall
      otherwise collect
      moneys which are determined to constitute interest which would otherwise
      increase the interest
      on any or all of the Obligations to an amount in excess of that permitted to
      be
      charged by applicable
      law then in effect, then all such sums determined to constitute interest in
      excess of such
      legal limit shall, without penalty, be promptly applied to reduce the then
      outstanding principal
      of the related Obligations or, at Lender's or such holder's option, promptly
      returned to Borrowers
      or the other payor thereof upon such determination. In determining whether
      or
      not

    

    
      
        
          
            921350_11

          

        

         

      

      
         

        
          

        

      

      
         

        
        

      

    

    the
      interest paid or payable under any specific circumstance exceeds the maximum
      amount permitted
      under applicable law, Lender and Borrowers (and any other payors thereof) shall
      to the greatest
      extent pemiitted under applicable law, (x) characterize any non-principal
      payment as an expense,
      fee or premium rather than as interest, (y) exclude voluntary prepayments and
      the effects
      thereof, and (z) amortize, prorate, allocate and spread the total amount of
      interest throughout
      the entire contemplated term of the instruments evidencing the Obligations
      in
accordance
      with the amounts outstanding from time to time thereunder and the maximum legal
      rate of interest from time to time in effect under applicable law in order
      to
      lawfully charge the maximum amount of interest permitted under applicable
      law.

     

    Section
      11.7 Termination;
      Limited Survival. In
      their
      sole and absolute discretion, Borrowers and Lender may each, at any time that
      no
      Obligations are owing, elect in a notice delivered
      to the other to terminate this Agreement. Upon receipt of such a notice, if
      no
Obligations
      are then owing, this Agreement and all other Loan Documents shall thereupon
      be
      terminated and the parties thereto released from any prospective obligations
      thereunder. Notwithstanding
      the foregoing or anything herein to the contrary, any waivers or admissions
      made
      by
      Borrowers or Lender in any Loan Documents, and any obligations which any Person
      may
      have
      to indemnify or compensate Lender shall survive any termination of this
      Agreement or any other Loan Document. At the request and expense of Borrowers,
      Lender shall prepare and execute
      all necessary instruments to reflect and effect such teiiiiination of the Loan
      Documents; provided,
      however, that
      nothing in this Section
      11.7
      shall
      affect any and all continuing rights, validity
      and enforceability of the ORRI.

     

    Section
      11.8 Severability.
      If
      any
      teiin or provision of any Loan Document shall be deteimined to be illegal or
      unenforceable, all other terms and provisions of the Loan Documents shall
      nevertheless remain effective and shall be enforced to the fullest extent
      permitted by applicable law.

     

    Section
      11.9 Counterparts.
      This
      Agreement may be separately executed in any number
      of
      counterparts and by different parties hereto in separate counterparts, each
      of
      which when
      so
      executed shall be deemed to constitute one and the same Agreement.

      Assurances. The
      parties agree (a) to furnish upon request to each
      other such information, (b) to execute and deliver to each other such documents,
      and (c) to do
      such
      other acts and things, all as the other party may reasonably request for the
      purpose of carrying
      out the intent of this Agreement and the Loan Documents.

      if no
      Event of Default exists, Borrowers may,
      from
      time to time and prior to the spudding of a well on an undeveloped Lease or

provided,
      however, that
      Borrowers shall not be authorized to Sell a Promoted Interest under this

      Borrowers'
      remaining Net Revenue Interest in the applicable Lease or Unit would be less

      ORRI on Promoted Interests. Notwithstanding
      Borrowers' Sale of
      a
      Promoted Interest pursuant to this Section
      11.13,
      Lender
      will be entitled to receive and
      Borrowers shall convey to Lenders the ORRI in accordance with Section
      8.4 above,
      proportionately
      reduced to the highest Working Interest to which Borrower is or may become

      to
      which
      such Promoted Interest was Sold.

     

    (e) Partial
      Release of Lien on Promoted Interests. To
      the
      extent Borrowers Sell
      a
      Promoted Interest in accordance with the terms and conditions of this
Section
      11.13,
      Lender
      agrees, upon the written request of Borrowers, to promptly execute and
deliver
      to Borrowers a mutually acceptable release of Lender's Lien on such Promoted
      Interest.

      12.1 Arbitration.Borrowers and
      Lender and any other obligor party (the "parties")
      will
      attempt in good faith to resolve any controversy or dispute arising out of
      or
relating
      to this Agreement, the Loan Documents or Collateral promptly by negotiations
      between themselves.
      The negotiation process may be started by the giving of written notice by any
      party to
      the
      other parties in accordance with the terms of Section
      11.3,
      and
      the
      parties agree to negotiate
      in good faith, and select an independent mediator to facilitate the negotiations
      and conduct up to eight consecutive hours of mediated negotiations in Houston,
      Texas within 30 days after the notice is first sent. If, within 10 days after
      the initial notice, the parties are not able to agree
      upon a mediator, the party originally giving the notice shall promptly notify
      American Arbitration
      Association ("AAA"), 1331 Lamar, Suite 1180, Houston, Texas 77010, (713)
      739-1302.
      AAA
      will promptly designate a mediator who is independent and impartial, and AAA's
      decision
      about the identity of the mediator will be final and binding.

     

    (a) No
      arbitration may be commenced by any party unless and until a negotiation
      complying with the foregoing paragraph has been completed, and no litigation
      or
      other proceeding may ever be instituted at any time in any court for the
purpose
      of adjudicating, interpreting or, except as may be set forth in Section
      12.1(h), enforcing
      any rights or obligations of the parties hereto or any rights or obligations
      relating
      to the subject matter hereof, whether or not covered by the express terms of
      this Agreement,
      or for the purpose of adjudicating a breach or determination of the validity
      of
this
      Agreement, or for the purpose of appealing any decision of an
      arbitrator.

     

    (b) If
      a
      controversy or dispute is not resolved after completion of the negotiation
      process described above, then, upon notice by any party to the other parties
      (an
      "Arbitration
      Notice") and
      to
      AAA, the controversy or dispute shall be submitted to an arbitration
      panel for binding arbitration in Houston, Texas, in accordance with AAA's
Commercial
      Arbitration Rules (the "Rules").
      The
      parties agree that they will faithfully observe
      this Agreement and the Rules and that they will abide by and perform any
      award

    rendered
      by the arbitration panel. The arbitration shall be governed by the Federal
      Arbitration Act, 9 U.S.C. Section 1-16 (or by the same principles enunciated
      by
      such Act in
      the
      event it may not be technically applicable). The award or judgment of the
arbitration
      panel shall be final and binding on all parties and judgment upon the award
      or
judgment
      of the arbitration panel may be entered and enforced by any court having
jurisdiction.
      If any party becomes the subject of a bankruptcy, receivership or other
similar
      proceeding under the laws of the United States of America, any state or
      commonwealth or any other nation or political subdivision thereof, then, to
      the
      extent permitted
      or not prohibited by applicable law, any factual or substantive legal issues
      arising
      in or during the pendency of any such proceeding shall be subject to all of
      the
      foregoing mandatory mediation and arbitration provisions and shall be resolved
      in accordance
      therewith. The agreements contained herein have been given for valuable
consideration,
      are coupled with an interest and are not intended to be executory contracts.
      The
      fees
      and expenses of the arbitration panel will be shared by all parties engaged
      in
      the dispute
      or controversy on a basis determined to be fair and equitable by the arbitrator,
      taking
      into account the relative fault of each party, the relative credibility and
      merit of all claims
      and defenses made by each party and the cooperation, speed and efficiency of
      each
      party in conducting the arbitration proceedings and complying with the Rules
      and
with
      orders and requests of the arbitrator.

     

    (c) Promptly
      after the Arbitration Notice is given, each party will select an independent
      and
      impartial arbitrator who will in turn select an independent and impartial
third
      arbitrator (each such arbitrator must be experienced or have extensive
      familiarity with
      the
      oil and gas industry). If the arbitrators selected by the parties are unable
      to
      agree on
      a
      third arbitrator, then one of the parties shall notify AAA and AAA shall select
      the third
      arbitrator with oil and gas industry experience or familiarity. The decision
      of
      AAA with respect to the selection of the arbitrator will be final and binding
      in
      such case. Such three
      arbitrators will constitute the arbitration panel.

     

    (d) Within
      10
      days after the selection of the arbitration panel, the parties and their
      counsel will appear before the arbitration panel at a place and time in Houston,
      Texas,
      as
      may be designated by the arbitration panel for the purpose of each party making
      a
      one
      hour or less presentation and summary of the case. Thereafter, the arbitration
      panel will
      set
      dates and times for additional hearings until the proceeding is concluded.
      The
      desire and goal of the parties is, and the arbitration panel will be advised
      that its goal should
      be, to conduct and conclude the arbitration proceeding as expeditiously as
      possible. If any party or his counsel fails to appear at any scheduled hearing,
      the arbitration
      panel shall be entitled to reach a decision based on the evidence which has
      been
      presented to it by the parties who did appear. Any arbitral award may be
      confirmed by a Texas state court.

     

    (e)
      Any
      arbitral award may be enforced in the courts of the state of Texas or
of
      the
      United States of America for the Southern District of Texas, and, by execution
      and delivery
      of this Agreement, the parties hereby accept for themselves and in respect
      of
their
      property, generally and unconditionally, the nonexclusive jurisdiction of the
      aforesaid courts for said purpose and the parties hereby irrevocably waive
      to
      the fullest extent
      permitted by law any objection, including without limitation, any objection
      to

conditions
      of this Agreement.
