                        ASSET PURCHASE AND SALE AGREEMENT

        This Asset Purchase and Sale Agreement (this "Agreement") is made and
entered into as of this 7th day of August, 2007, by and between DSX Energy
Limited, LLP, a Texas limited liability partnership ("DSX"), having as its
address 800 N. Shoreline Blvd., Suite 2570S, Corpus Christi, Texas 78401, KEBO
Oil & Gas, Inc. a Texas corporation ("KEBO") having as its address 607 Railroad
Avenue, Portland, Texas 78371, and the remaining parties identified on the
signature pages to this Agreement under the caption "Sellers" (subject to the
terms of Section 1.1.2, each a "Seller", and collectively, "Sellers"), and
Baseline Oil & Gas Corp., a Nevada corporation, having as its address 11811
North Freeway, Suite 200, Houston, Texas 77060 ("Purchaser"). Sellers and
Purchaser are sometimes collectively referred to in this Agreement as the
"Parties" or individually as a "Party".

                              W I T N E S S E T H:

      WHEREAS, Sellers are the owners of undivided interests in and to the
Assets (as defined below); and

      WHEREAS, KEBO is the current operator of record with respect to all of the
Assets; and

      WHEREAS, Sellers are willing to sell and deliver to Purchaser, and
Purchaser is willing to purchase and receive from Sellers, all of the rights and
interests of Sellers in and to the Assets upon the terms and conditions set
forth in this Agreement.

      NOW, THEREFORE, for and in consideration of the mutual promises of the
Parties contained in this Agreement and other good and valuable consideration,
the receipt and sufficiency of which are hereby acknowledged, the Parties agree
as follows:

                              1. PURCHASE AND SALE

1.1     Agreement to Sell and Purchase.

1.1.1   Subject to the terms and conditions of this Agreement, Purchaser agrees
        to purchase and receive from Sellers, and Sellers agree to sell, assign,
        transfer, convey, and deliver to Purchaser all of Sellers' rights and
        interests in and to the Assets, as of the Effective Date (as defined
        below).

1.1.2   Schedule 1.1.2 attached hereto identifies the owners of interests in the
        Assets in addition to DSX and KEBO ("Possible Sellers") and the
        corresponding percentage of the Full Interest Purchase Price (as defined
        below) allocable to each Possible Seller based upon its respective
        ownership interests in the Assets (in each case, its "Allocation
        Percentage"). Immediately following the execution of this Agreement by
        DSX, KEBO, and Purchaser, DSX shall circulate this Agreement among the
        Possible Sellers for execution. Each Possible Seller shall have until
        6:00 p.m., Central Daylight Time, on the third Business Day after the
        date on which this Agreement is executed by DSX and Purchaser (the
        "Participation Period") within which to evidence its election to
        participate in the sale of the Assets contemplated herein by executing
        and returning to Purchaser a counterpart of the signature page for this
        Agreement prepared for such Possible Seller. The failure of a Possible




        Seller to execute and return to Purchaser its signature page for this
        Agreement prior to the expiration of the Participation Period shall
        constitute an election by such Possible Seller not to sell its interests
        in the Assets to Purchaser. Subject to the terms of Sections 1.1.3 and
        2.3.1, upon the execution by a Possible Seller and return to Purchaser
        of such Possible Seller's signature page for this Agreement in a timely
        manner as provided in this Section 1.1.2, the terms of this Agreement
        shall become binding on and enforceable against such Possible Seller,
        and such Possible Seller shall become a "Seller" for purposes of this
        Agreement.

1.1.3   Notwithstanding the execution of this Agreement by DSX and one or more
        Possible Sellers in accordance with Section 1.1.2, if, prior to the
        expiration of the Participation Period, Sellers having, in the
        aggregate, Allocation Percentages of less than ninety-two percent (92%)
        do not execute and return to Purchaser signature pages for this
        Agreement in accordance with Section 1.1.2, Purchaser shall have the
        right to terminate this Agreement. If this Agreement is thus terminated
        by Purchaser, neither DSX, KEBO, the Possible Sellers who execute and
        return to DSX signature pages for this Agreement in accordance with
        Section 1.1.2, nor Purchaser shall have any further obligation or
        liability to the other Party under this Agreement or otherwise in
        connection with the transactions contemplated herein, subject, however
        to the terms of Section 14.2. If, prior to the expiration of the
        Participation Period, Possible Sellers having, in the aggregate,
        Allocation Percentages equal to or greater than ninety-two percent (92%)
        execute and return to Purchaser signature pages for this Agreement in
        accordance with Section 1.1.2, (i) Purchaser shall become obligated to
        tender to Sellers the Performance Deposit in accordance with the terms
        of Section 2.3.1, and (ii) Purchaser and Sellers shall execute an
        amendment to this Agreement that (w) establishes the Purchase Price (as
        defined below) in accordance with Section 2.2, (x) adds to this
        Agreement the final version of Exhibit B reflecting the undivided
        Working Interests of Sellers in each Well (as defined below) and the
        Allocated Value (as defined below) for such Well, (y) adds to this

Records. If, however, Purchaser elects to destroy any of the Records, either
before or after the expiration of such seven (7) year period, Purchaser shall
give to Sellers written notice of such intent at least thirty (30) days prior to
such destruction, and Sellers shall have the option, at its expense, of having
such Records delivered to it. SELLERS MAKE NO REPRESENTATIONS OR WARRANTIES WITH

RESPONSIBILITY FOR ANY CONSEQUENCES BASED UPON, PURCHASER'S USE OF, OR RELIANCE
UPON, THE RECORDS.

or damage to property, relating in any way to, the Assets that occurred prior to

                              2. SALE AND PURCHASE

2.1 Purchase and Sale. At the Closing, Sellers shall sell, assign, transfer, and
convey to Purchaser, and Purchaser shall purchase and pay for, the Assets, and
Purchaser shall also assume the Assumed Obligations as set forth in Section
13.3.4.

2.2 Purchase Price. The purchase price to be paid by Purchaser to Sellers with
respect to the Assets (the "Purchase Price") shall equal the product obtained by
multiplying (i) the aggregate Allocation Percentages of DSX, KEBO, and those
Possible Sellers who execute and return to Purchaser signature pages for this
Agreement in a timely manner in accordance with Section 1.1.2, by (ii) ONE
HUNDRED MILLION AND NO/100 Dollars U.S. ($100,000,000.00) (the "Full Interest
Purchase Price"). If all Possible Sellers execute and return to Purchaser
signature pages for this Agreement in a timely manner in accordance with Section
1.1.2, the Purchase Price shall equal the Full Interest Purchase Price. To the
extent that the Purchase Price is less than the Full Interest Purchase Price,
such shortfall shall not be taken into account in determining whether (y) the
Deductible (as defined below) has been met for purposes of Section 3.5.2 or
Section 5.5.2, or (z) the Termination Threshold (as defined below) has been met
for purposes of Section 3.8. The amount of the Purchase Price is set in
consideration of Purchaser's assumption of the Assumed Obligations as set forth
in Section 13.3.4.


                                     Page 11


2.3     Performance Deposit.

2.3.1   If Possible Sellers having, in the aggregate, Allocation Percentages
        equal to or greater than ninety-two percent (92%) execute and return to
        Purchaser signature pages for this Agreement in accordance with Section
        1.1.2, Purchaser, as evidence of Purchaser's good faith intention to
        consummate the transactions contemplated hereby, shall tender to DSX, on
        behalf of Sellers, no later than 6:00 p.m., Central Daylight Time, on
        the second Business Day after the Participation Date, a cash performance
        deposit in the amount of TWO MILLION FIVE HUNDRED THOUSAND AND NO/100
        Dollars U.S. ($2,500,000.00) (the "Performance Deposit"). If Purchaser
        fails to tender to Sellers the Performance Deposit in a timely manner as
        provided in the immediately preceding sentence of this Section 2.3.1,
        Sellers shall have the right to terminate this Agreement. If this
        Agreement is thus terminated by Sellers, neither Sellers nor Purchaser
        shall have any further obligation or liability to the other Party under
        this Agreement or otherwise in connection with the transactions
        contemplated herein, subject, however, to the terms of Section 14.2.

2.3.2   If Sellers terminate this Agreement in accordance with Section 14.1.2 or
        Section 14.1.5 hereof, Sellers shall retain the Performance Deposit as
        liquidated damages; provided that nothing contained herein shall
        prohibit Purchaser from contesting the basis for Sellers' decision to
        terminate and seeking recovery of such Performance Deposit through any
        legal means available to it. The Parties agree that the Performance
        Deposit is a reasonable sum considering all the circumstances existing
        on the date of this Agreement, including the relationship of the sum to
        the range of harm to Sellers that reasonably could be anticipated and
        the anticipation that proof of actual damages would be costly or
        inconvenient. If this Agreement is otherwise terminated for any reason
        by either Sellers or Purchaser pursuant to the terms thereof, the
        Performance Deposit shall be returned to Purchaser, except to the extent
        otherwise provided in Section 8.10. In the event the transactions
        contemplated herein close, the Performance Deposit shall be retained by
        Sellers and credited against the Purchase Price payable by Purchaser
        hereunder.

2.4 Determination of Adjusted Purchase Price. The net purchase price for the
Assets (the "Adjusted Purchase Price") shall be determined as follows:

        from or allocable to the Properties existing in pipelines, storage
        tanks, or other processing or storage facilities (including, without
        limitation, unsold inventories of plant products owned by Sellers if
        any) upstream of the delivery points to the relevant purchasers as of
        the Effective Date, the value to be based on the contract price
        applicable to such Hydrocarbons in effect as of the Effective Date (or
        the market value, if there is no contract price, in effect as of the
        Effective Date), less amounts payable as royalties, overriding
        royalties, and other, similar burdens upon such Hydrocarbons;

2.4.3   Plus the amount of all actual expenditures made or prepaid by Sellers
        that are incurred in connection with the Assets which are attributable

        including, without limitation: rentals, shut-in well payments, and other
        lease maintenance payments; operating costs; premiums on insurance
        policies allocable to the period on and after the Effective Date through
        the Closing Date; capital costs (including, without limitation, all
        drilling costs, completion costs, acreage expenditures, acquisition
        expenditures, seismic expenditures, and waterflood expenditures); and

        Sellers by the operator or operators (including, without limitation,
        KEBO or its Affiliates) of the Assets under applicable operating
        agreements (or if KEBO or its Affiliate is the operator in the absence
        of an operating agreement, the charges provided in Section 8.3 hereof),
        including, without limitation, unreimbursed expenses paid by Sellers on
        behalf of third parties to which Sellers are entitled to reimbursement
        under such operating agreements;

        determined in accordance with Section 3.7, and the amount of any

        ordinary course of business that are attributable to Hydrocarbon
        production from the Properties on and after the Effective Date through
        the Closing Date (net of any royalties and of any production, severance,
        sales, or other taxes actually paid by or on behalf of Sellers),
        together with any other monies or credits attributable to the ownership
        or operation of the Assets on and after the Effective Date through the
        Closing Date;

2.4.7   Less the amount of the Performance Deposit and all other advances and
        deposits relating to the Assets that are received by Sellers prior to
        the Closing Date and attributable to periods of time on or after the
        Effective Date;

2.4.8   Less an amount equal to the aggregate of all Title Indemnity Payments
        made in accordance with Article 3;

to an escrow agent determined by Sellers, an amount in immediately available
U.S. funds equal to the Purchase Price, plus or minus the adjustments provided

be required by the IRC and regulations thereunder or other Applicable Laws,
Sellers and Purchaser agree (i) that for tax reporting purposes, the Purchase
Price shall be allocated among the Assets as set forth in the final version of
Exhibit J attached to this Agreement pursuant to Section 1.1.3, and such
allocation shall be used in preparing Internal Revenue Service Form 8594 ("Form
8594") pursuant to the regulations under Section 1060 of the Code, and (ii) not
to assert, in connection with any tax return, tax audit, or similar proceeding,
any allocation of the Purchase Price that differs from that set forth in Exhibit
J to this Agreement. In the event of any adjustment of the Purchase Price
pursuant to the terms of this Agreement, Sellers and Purchaser shall adjust the
allocations reflected in Exhibit J accordingly and report such adjustments in
conformity with Section 1060 of the Code and the regulations thereunder.

and copying by Purchaser and shall grant to Purchaser access to such Properties

provide abstracts other than those presently in such Seller's possession, nor
will any existing title opinions be made current by any Seller. Sellers will use
reasonable commercial efforts to furnish to Purchaser all other information with
respect to the Assets that Purchaser may from time to time reasonably request,
except to the extent that any Seller determines in good faith that it is
prohibited by agreement with a third party from disclosing the information
covered thereby. Purchaser agrees to conduct its due diligence in a professional
and orderly manner and at its own cost and expense without disruption of any
Seller's normal and usual operations. PURCHASER SHALL INDEMNIFY AND HOLD
HARMLESS EACH SELLER, AND ITS AFFILIATES, TOGETHER WITH THEIR RESPECTIVE
PARTNERS, CO-VENTURERS, SHAREHOLDERS, MEMBERS, OFFICERS, DIRECTORS, TRUSTEES,
EMPLOYEES, AGENTS (INCLUDING, WITHOUT LIMITATION, RICHARDSON BARR SECURITIES,
INC.), AND REPRESENTATIVES (COLLECTIVELY, THE "SELLERS' GROUP"), FROM ANY AND
ALL CLAIMS, DEMANDS, DAMAGES, LOSSES, LIABILITIES, COSTS AND EXPENSES, INCLUDING
COURT COSTS AND REASONABLE ATTORNEY'S FEES (COLLECTIVELY, "COSTS"), ARISING OUT
OF, OR RESULTING FROM PURCHASER'S ACTS OR OMISSIONS IN CONNECTION WITH ITS
ACCESS TO THE ASSETS, REGARDLESS OF WHETHER SUCH COSTS ARE ATTRIBUTABLE, IN
WHOLE OR IN PART, TO THE NEGLIGENCE, SOLE OR CONCURRENT, OF THE SELLERS' GROUP.

3.2 Definitions. For purposes of this Agreement, the following expressions and
terms will have the meanings set forth hereinafter:

3.2.1   "Sellers' Title" shall mean, as to each Well, that (i) Sellers (and upon
        Closing, Purchaser), by virtue of their ownership interests therein, are
        collectively entitled to receive a fractional decimal interest of not
        less than the "Net Revenue Interest" set forth for each Well on Exhibit
        B, without reduction, suspension, or termination throughout the
        productive life of each Well (unless otherwise shown on Exhibit B); (ii)
        Sellers are collectively obligated to bear (and after the Closing,
        Purchaser shall be obligated to bear) a fractional decimal interest of
        not more than the "Working Interest" set forth for each Well on Exhibit
        B of the costs and expenses related to the maintenance, development,
        drilling, equipping, testing, completion, sidetracking, reworking and
        operation of each such Well, without increase throughout the productive
        life thereof (unless otherwise shown on Exhibit B); and (iii) such Well
        is free and clear of liens, encumbrances, and other defects or
        irregularities in title, except for Permitted Encumbrances.

3.2.2   "Permitted Encumbrances" shall mean:

        (a)    lessors' royalties, overriding royalties, payments out of
               production, reversionary interests, and other similar burdens
               affecting the aggregate Net Revenue Interest of all parties
               comprising Sellers if the net cumulative effect of such burdens
               does not operate to (i) reduce the aggregate Net Revenue Interest
               of Sellers in any Well to less than the Net Revenue Interest set
               forth for such Well in Exhibit B; or (ii) increase the aggregate
               Working Interest of Sellers in any such Well to greater than the


                                     Page 15


               Working Interest set forth for such Well in Exhibit B (unless the
               aggregate Net Revenue Interest of Sellers therein is increased in
               the same proportion);

        (b)    preferential rights to purchase, required third party consents to
               assignment, and similar agreements with respect to which, prior
               to the Closing, (i) waivers or consents are obtained from the
               appropriate parties; (ii) the appropriate time for asserting such
               rights has expired without an exercise of such rights; (iii) with
               respect to consents, such consent need not be obtained prior to
               assignment, or the failure to obtain such consent will not have a
               material adverse effect on the value of the affected Well, or may
               not reasonably be expected to subject Purchaser to liability in
               favor of any third party;

        (c)    all rights to consent by, required notices to, filings with, or
               other actions by Governmental Bodies in connection with the sale
               or conveyance of the Assets if the same are customarily obtained
               subsequent to such sale or conveyance;

        (d)    non-consent penalties applied against the interest of any Sellers
               arising under applicable operating agreements which are scheduled
               on Exhibit C and taken into account in the calculation of the
               interests shown on Exhibit B;

        (e)    easements, rights-of-way, servitudes, permits, surface leases,
               and other rights in respect of surface operations that are not a
               part of, but that burden, the Assets;

        (f)    such Title Defects as Purchaser has waived or released or is
               deemed to have waived pursuant to the terms of this Agreement;

        (g)    the terms and conditions of all Existing Contracts; provided,
               however, that the effect of such terms and conditions is
               reflected in the calculation of the Working Interests and Net
               Revenue Interests set forth for the Wells in Exhibit B;

        (h)    rights of reassignment, to the extent any exist as of the date of
               this Agreement, upon the surrender or expiration of any Lease;

        (i)    liens for taxes not yet due or not yet delinquent or, if due or
               delinquent, that are being contested in good faith;

        (j)    materialman's, mechanic's, repairman's, employee's, contractor's,
               operator's, and other similar liens or charges encumbering the
               Assets that arise in the ordinary course of business (i) if they
               have not been filed pursuant to Applicable Law, (ii) if filed,
               they have not yet become due and payable, or payment is being
               withheld as provided by Applicable Law, or (iii) if their
               validity is being contested in good faith by appropriate action;

        (k)    all rights reserved to or vested in any Governmental Body to
               control or regulate any of the Assets in any manner, and all
               Applicable Laws;


                                     Page 16


        (l)    all defects and irregularities of title that would not reasonably
               be expected to result in claims that would materially and
               adversely affect the title of any Seller to, or the ownership,
               operation, or value of, the Assets, including, without limitation
               (i) defects in the early chain of title consisting of the failure
               to recite marital status or the omission of succession or
               heirship proceedings; (ii) defects or irregularities arising out
               of the lack of a survey (but not defects or irregularities, the
               existence of which is demonstrated by a survey); (iii) defects or
               irregularities arising out of or relating to the lack of powers
               of attorney from corporations to execute and deliver documents on
               their behalf or lack of spousal joinder; (iv) defects of title
               which result from the failure to file assignments or other
               documents in the state or federal records so long as such
               assignments or other documents are properly recorded in the
               county records; and (v) irregularities cured by possession under
               applicable statutes of limitation and statutes relating to
               acquisitive (or liberative) prescription; and

        (m)    all other liens, charges, encumbrances, instruments, obligations,
               defects and irregularities affecting the Assets which,
               individually or in the aggregate, do not: (i) interfere
               materially with the operation, value, or use of any of the Wells;
               (ii) do not prevent Purchaser from receiving the proceeds of
               production from any of the Wells; (iii) do not reduce the
               aggregate interests of all Sellers with respect to Hydrocarbons
               produced from any Well below the Net Revenue Interest set forth
               for such Well on Exhibit B; or (iv) do not increase the aggregate
               share of the costs and expenses that Sellers are obligated to pay
               above the Working Interest set forth for such Well in Exhibit B
               without a proportionate increase in the Net Revenue Interest for
               such Well.

3.2.3   "Title Defect" shall mean any matter: (i) that would cause the title to
        any Well fail to be as reflected in Sellers' Title, or that reflects a
        failure in Sellers' title to any Property; (ii) has a Defect Value (as
        hereinafter defined) which is greater than $25,000; and (iii) as to
        which notice is provided to Sellers in a timely manner as provided for
        in Section 3.3.

3.2.4   "Allocated Value" means, with respect to each Well, the amount set forth
        on the final version of Exhibit B attached to this Agreement pursuant to
        Section 1.1.3 under the column styled "Allocated Value" for such Well.
        For purposes of this Agreement, Sellers and Purchaser agree and
        stipulate that the Allocated Values set forth in Exhibit B have been
        established solely for use in calculating adjustments to the Purchase
        Price as provided herein, and not for purposes of federal, state, local,
        or foreign income taxation, such Allocated Values being solely for the
        convenience of the Parties.

3.3 Notice of Title Defect. During the period of time between the execution of
this Agreement and September 21, 2007 (the "Due Diligence Period"), Purchaser
may review title to the Assets and may notify Sellers in writing (the "Title
Defect Notice") of any Title Defect; provided, however, Purchaser shall notify
Sellers of any Title Defect it discovers as soon as reasonably practicable after
its discovery. Any notice provided hereunder shall include appropriate evidence
to substantiate Purchaser's position, including a description of the Title
Defect, the basis for the Title Defect, the portion of the Well or Wells
affected by the Title Defect, the Allocated Value therefore, the amount by which
Purchaser reasonably believes, in accordance with the provisions of Section 3.6,


                                     Page 17


the value of the affected Well or Wells would be reduced if the Title Defect
were uncured (the "Defect Value"), and the computations and information upon
which Purchaser's belief is based. Purchaser will be deemed to have conclusively
waived any matter reflected in the public records of the county where the
Properties are located as of the end of the Due Diligence Period or in any
documents or records made available by Sellers to Purchaser pursuant hereto that
would otherwise qualify as a Title Defect but about which Purchaser fails to
notify Sellers in writing in the manner described above prior to the expiration
of the Due Diligence Period.

3.4 Remedies for Title Defects. For any Title Defect properly asserted by
Purchaser during the Due Diligence Period, subject to the termination rights of
both Parties pursuant to Section 3.8 hereof, Sellers shall have the option, in
their sole discretion, of (i) curing the Title Defect, (ii) contesting the Title
Defect or the Defect Value, or (iii) subject to the terms of Section 3.5.2,
reducing the Purchase Price by the amount of the Defect Value ("Title Indemnity
Payment").

3.5 Procedure for Resolving Title Defects. With respect to Title Defects
properly and timely asserted by Purchaser as provided herein, the following
procedures shall apply.

3.5.1   If Sellers contest the existence of a Title Defect or the Defect Value
        applicable thereto, Sellers shall so notify Purchaser in writing on or
        before five (5) days after Sellers' receipt of the Title Defect Notice
        ("Rejection Notice"). The Rejection Notice shall state with reasonable
        specificity the basis of Sellers' rejection of the Title Defect or the
        Defect Value. No later than five (5) days following Purchaser's receipt
        of the Rejection Notice, representatives of Purchaser and Sellers,
        knowledgeable in title matters, shall meet and either: (i) agree to
        mutually reject the particular Title Defect, or (ii) agree on the
        validity of such Title Defect and the Defect Value, in which case
        Sellers shall cure such Title Defect at their own expense and to their
        reasonable satisfaction and, failing such cure, make the Title Indemnity
        Payment therefor, subject to the limitations set forth in Section 3.5.2.
        If the Parties cannot agree on either option (i) or (ii) in the
        preceding sentence, the Title Defect or the Defect Value subject to the
        Rejection Notice shall be submitted to dispute resolution in accordance
        with the procedures set forth in Section 3.9. Each Title Defect as to
        which Sellers and Purchaser reach agreement hereunder concerning the
        validity of such Title Defect and its Defect Value or as to which such
        validity and/or Defect Value is finally determined pursuant to Section
        3.9 shall be referred to herein as a "Finally Determined Title Defect."

3.5.2   Notwithstanding the provisions of Section 3.5.1, and except as otherwise
        provided in Section 3.10, Sellers shall not be obligated to pay any
        Title Indemnity Payment, Environmental Indemnity Payment, or Casualty
        Loss Amount hereunder unless, and only to the extent that, the sum of
        (i) the aggregate Defect Values for all uncured, Finally Determined
        Title Defects, plus (ii) the aggregate Remediation Amounts for all
        unremedied Finally Determined Environmental Defects, plus (iii) the
        aggregate Casualty Loss Amounts for all unrepaired Finally Determined
        Casualty Losses, exceeds a deductible of five percent (5.0%) of the
        Purchase Price (the "Deductible"). If Purchaser asserts Finally
        Determined Title Defects for which Sellers elect to make a Title
        Indemnity Payment, and the sum of (x) the aggregate Defect Values for
        such uncured Finally Determined Title Defects plus (y) the aggregate
        Remediation Amounts for all unremedied Finally Determined Environmental


                                     Page 18


        Defects, plus (z) the aggregate Casualty Loss Amounts for all unrepaired
        Finally Determined Casualty Losses do not exceed the Deductible, no
        Title Indemnity Payment shall be made.

3.6 Value of Defects. The Defect Value for a Title Defect shall be determined as
follows:

3.6.1   If, because of the Title Defect, title to a particular Well fails
        completely with the effect that Sellers have no ownership interest in
        the relevant Well, the Defect Value shall be the Allocated Value of that
        Well.

3.6.2   If the Title Defect consists of a lien, encumbrance or other charge upon
        a Well which is liquidated in amount, the Defect Value shall be the
        amount necessary to pay the obligee to remove such Title Defect.

3.6.3   If the actual aggregate Net Revenue Interest of Sellers in a Well is
        less than the Net Revenue Interest set forth for such Well in Exhibit B
        throughout the remaining productive life of such Well, the Defect Value
        shall be an amount equal to (i) the ratio of (x) the difference obtained
        by subtracting the actual Net Revenue Interest for such Well from the
        Net Revenue Interest set forth for such Well on Exhibit B, to (y) the
        Net Revenue Interest set forth for such Well on Exhibit B, (ii)
        multiplied by the Allocated Value for such Well.

3.6.4   If the actual aggregate Net Revenue Interest of Sellers in a Well is
        less than the Net Revenue Interest set forth for such Well in Exhibit B
        for less than the remaining productive life of such Well, or if the
        actual aggregate Working Interest of Sellers in a Well is greater than
        the Working Interest set forth for such Well in Exhibit B without a
        proportionate increase in the relevant Net Revenue Interest, then the
        Defect Value shall be equal to the Allocated Value for such Well
        multiplied by a fraction (i) the numerator of which shall be the net
        present value, as of the Effective Date, of the aggregate interests of
        Sellers in the future net revenues from such Well set forth in that
        certain reserve report dated May 31, 2007, covering the Properties as of
        June 1, 2007, prepared by R. A. Lenser & Associates (the "Lenser Reserve
        Report"), a copy of which has been previously delivered to Purchaser,
        discounted at ten percent (10%) per annum (the "PV-NRI"), minus the net
        present value, as of the Effective Date, of the aggregate interests of
        Sellers in the future net revenues from such Well calculated based upon
        the same production, cost, and assumed future price estimates and such
        other methods, techniques and assumptions used in the preparation of the
        Lenser Reserve Report but taking into account the Title Defect, and (ii)
        the denominator of which shall be the PV-NRI.

3.6.5   If the Title Defect is one other than described in Sections 3.6.1
        through 3.6.4, the Defect Value shall be the amount agreed to by Sellers
        and Purchaser or, failing such agreement, the Defect Value shall be
        determined pursuant to Section 3.9 below.

3.7 Interest Additions. If Sellers discover that the actual aggregate Net
Revenue Interest of Sellers for a Well is greater than the Net Revenue Interest
shown for such Well on Exhibit B, and such Well is otherwise free of Title
Defects (an "Interest Addition"), then Sellers shall, from time to time, have
the right to give Purchaser written notice of such Interest Additions ("Interest


                                     Page 19


Addition Notice"), as soon as practicable but no later than the end of the Due
Diligence Period, stating with reasonable specificity the Well affected, the
particular Interest Addition claimed, and Sellers' good faith estimate of the
amount by which the Additional Interest increases the value of the affected Well
over and above the Allocated Value for such Well ("Interest Addition Value"). If
Purchaser agrees with the existence of the Interest Addition and Sellers' good
faith estimate of the Interest Addition Value, and such Interest Addition Value
exceeds $25,000, then the Interest Addition Value shall be applied as an offset
to any Title Indemnity Payment or Environmental Indemnity Payment required of
Sellers ("Offset"). If Purchaser contests the existence of the Interest Addition
or Sellers' good faith estimate of the Interest Addition Value, then Purchaser
shall so notify Sellers in writing on or before five (5) days after receipt of
the Interest Addition Notice ("Interest Addition Rejection Notice"). The
Interest Addition Rejection Notice shall state with reasonable specificity the
basis of Purchaser's rejection of the Additional Interest or the Interest
Addition Value. No later than five (5) days following delivery of the Interest
Addition Rejection Notice, representatives of Purchaser and Sellers,
knowledgeable in title matters, shall meet and either (i) agree to mutually
reject the Interest Addition, in which case Sellers shall waive the Interest
Addition, or (ii) agree on the validity of such Interest Addition and the
Interest Addition Value, in which case Sellers shall be entitled to an Offset.
If the Parties cannot agree on either option (i) or (ii) in the preceding
sentence, the Interest Addition subject to the Interest Addition Rejection
Notice shall be submitted to dispute resolution in accordance with the
procedures set forth in Section 3.9. If Purchaser fails to timely deliver an
Interest Addition Rejection Notice, Purchaser shall be deemed to have accepted
the validity of the Interest Addition and the Interest Addition Value, and
Sellers shall be entitled to an Offset as described above.

3.8 Right to Terminate Agreement. Notwithstanding anything in Article 3, Article
4 or Article 5, if the sum of (i) the Defect Values for all Finally Determined
Title Defects (which, for purposes of this Section 3.8, shall include
preferential rights to purchase and required third person consents to assignment
that result in the exclusion of one or more Assets from the Closing pursuant to
Section 3.10, but shall exclude liens, encumbrances, or other charges upon a
Well as to which Sellers obtain releases upon Sellers' payment or discharge of
the indebtedness or other obligations secured thereby), plus (ii) the
Remediation Amounts for all Finally Determined Environmental Defects, plus (iii)
the Casualty Loss Amounts for all Finally Determined Casualty Losses that occur
prior to the Closing Date, equals or exceeds, independently of and without
regard to the Deductible, fifteen percent (15%) of the Full Interest Purchase
Price (the "Termination Threshold"), and Sellers elect not, or are unable, to
cure, remedy, or repair such Finally Determined Title Defects, Finally
Determined Environmental Defects, or Finally Determined Casualty Losses, either
Party may elect to terminate this Agreement without liability to the other
Party, in which case Purchaser shall be entitled to a refund of the Performance
Deposit.

3.9     Expert Determination.

3.9.1   If Sellers and Purchaser are unable to agree, as herein provided,
        regarding the existence of a Title Defect, Environmental Defect, or
        Casualty Loss, the applicable Defect Value, Remediation Amount (as
        hereinafter defined), or reduction in value resulting from a Casualty
        Loss, or any other matter to be resolved under this Article 3, Article
        4, or Article 5, the Parties shall promptly refer the matter for
        determination in the manner hereinafter provided to a person selected by


                                     Page 20


        mutual agreement of the Parties who possesses the requisite knowledge,
        skill and experience to determine the issue in question (the "Defect
        Expert"). The Defect Expert may enlist the advice of attorneys,
        accountants, geologists, landmen, or any petroleum engineer or
        environmental consultant mutually agreed upon by the Parties and any
        other neutral expert as reasonably necessary.

3.9.2   Upon referral to the Defect Expert, the Parties shall each deliver to
        the other and the Defect Expert a notice setting forth in adequate
        detail the issues to be determined by the Defect Expert and the decision
        (on a word-for-word basis) that such Party wishes the Defect Expert to
        make with respect to the issues to be determined (the "Decision
        Notice"); provided, however, in preparing their Decision Notice, each
        Party (as well as the Defect Expert) shall be bound by the terms of this
        Agreement. Within two (2) business days after the giving of the two
        Decision Notices, the Parties shall attend a meeting with the Defect
        Expert at a mutually acceptable time and place to discuss fully the
        content of such Decision Notice and, based thereon, determine whether
        either or both wish to modify their Decision Notices in any way. Any
        such modifications shall be discussed, so that when each Party finalizes
        its Decision Notice, it shall do so with full knowledge of the content
        of the other Party's final Decision Notice. The finalization of such
        Decision Notices and the delivery of same by each Party to the other
        shall occur at the meeting unless the Parties agree to have one or more
        additional meetings for such purposes. The Defect Expert shall be
        required to adopt the decision set forth in either final Decision Notice
        and shall have no power whatsoever to reach any other result. Such
        Defect Expert shall adopt the decision that, in his or her judgment, is
        the more fair and equitable and in conformity with this Agreement and
        industry standards.

3.9.3   The decision, made in writing and signed by the Defect Expert, shall
        determine such dispute. Such decision shall be made, signed and
        delivered to the Parties at the meeting unless otherwise agreed by the
        Parties. The expenses of the Defect Expert and any other expert retained
        by the Defect Expert under this Agreement shall be borne by the Party
        whose final Decision Notice was not chosen by the Defect Expert, except
        that each Party shall bear the compensation and expense of its own
        counsel, witnesses and employees. The determination and award of the
        Defect Expert shall be final and binding upon the Parties, and judgment
        may be entered thereon in any court of competent jurisdiction upon the
        application of either Party.

3.10    Preferential Purchase Rights and Consents to Assign.

3.10.1  Within five (5) days after the execution of this Agreement, Sellers
        shall send to the holder of each preferential right to purchase
        identified on Exhibit D a written notice offering to sell to such
        holder, in accordance with the contractual provisions applicable to such
        right, the Asset covered by such right on substantially the same terms
        as this Agreement and for the Allocated Value applicable to such Asset
        as set forth in Exhibit B, subject to adjustments in price in the same
        manner that the Purchase Price is adjusted pursuant to Section 2.4 of
        this Agreement. Similarly, within five (5) days after the execution of
        this Agreement, Sellers shall send to each party identified on Exhibit D
        from whom a consent to assignment is required prior to the Closing a
        written notice requesting such party to consent to the assignment of the
        affected Asset to Purchaser. Both Purchaser and Sellers shall use


                                     Page 21


        reasonable efforts to identify additional preferential rights to
        purchase and consents to assign and, if any such rights are identified,
        Sellers shall notify such holder(s) in accordance with the terms of this
        Section 3.10.1 within five (5) days of the identification of such
        additional rights.

3.10.2  If an Asset (including, without limitation, an Existing Contract) is
        subject to a preferential right to purchase, right of first refusal,
        right of first offer, or similar right that is exercised prior to the
        Closing, then at Purchaser's option, (i) Sellers shall convey the
        affected Asset to Purchaser at the Closing subject to such outstanding
        preferential right to purchase or similar right, or (ii) the affected
        Asset shall be excluded from the Assets conveyed to Purchaser at the
        Closing, the Purchase Price shall be reduced by an amount equal to the
        full Allocated Value of the affected Asset without regard to the
        existence or status of amounts credited against the Deductible, and
        Sellers shall be entitled to retain all proceeds paid for the affected
        Asset by the person exercising such preferential right to purchase or
        similar right. No reduction of the Purchase Price pursuant to this
        Section 3.10.2 shall be taken into account in determining whether the
        Deductible has been met. If Purchaser purchases at the Closing an Asset
        burdened by a preferential right to purchase or similar right that has
        not been exercised as of the Closing Date, regardless of whether the
        time period for the exercise of such right has expired, no reduction of
        the Adjusted Purchase Price paid at the Closing shall be made with
        respect thereto. If, for any reason, such preferential right to purchase
        or similar right is successfully exercised by the holder thereof after
        the Closing, Purchaser shall be entitled to retain all proceeds paid for
        the affected Asset by the holder of the relevant preferential right to
        purchase or similar right. If the holder of such a preferential right to
        purchase or similar right notifies Sellers that it intends to consummate
        the purchase of an Asset to which its preferential purchase right
        applies, but the holder of such preferential right fails to consummate
        the purchase of the relevant Asset such that the holder's right expires
        or is terminated, whether before or after Closing, then Sellers, as
        promptly as possible thereafter, but in no event later than one hundred
        fifty (150) days after the Closing, shall so notify Purchaser. Within
        fifteen (15) days after Purchaser's receipt of such notice from Sellers,
        Sellers shall sell to Purchaser, and Purchaser shall purchase from
        Sellers, for a price equal to the Allocated Value of such Asset and
        subject to and in accordance with the other terms of this Agreement, the
        Asset to which such preferential right to purchase or similar right
        applies.

3.10.3  If an Asset (including, without limitation, an Existing Contract) is
        subject to a third person consent to assignment required to be obtained
        before the relevant Asset may be assigned, but the third party holding
        such right to consent neglects or refuses to give such consent prior to
        the Closing, Sellers will promptly so notify Purchaser and, at
        Purchaser's option, (i) Sellers shall convey the affected Asset to
        Purchaser at the Closing subject to such outstanding consent, in which
        case the Allocated Value applicable to the affected Asset shall be
        included in the Purchase Price paid by Purchaser at the Closing, or (ii)
        the affected Asset shall be excluded from the Assets conveyed at
        Closing, title thereto shall be retained by Sellers subject to the terms
        of this Section 3.10.3, and the Purchase Price shall be reduced by an
        amount equal to the full Allocated Value of the affected Asset without
        regard to the existence or status of amounts credited against the
        Deductible. After the Closing, Sellers shall continue to use their
        reasonable commercial efforts (which shall in no event include any
        obligation to pay money to the owners of such rights or undertake any


                                     Page 22


        legal obligation) to obtain all consents to assignment as promptly after
        the Closing as is possible. If Sellers obtain the relevant outstanding
        consent to assignment, and Purchaser has elected to exclude the affected
        Asset from the Assets conveyed at Closing, then within fifteen (15) days
        after Sellers' receipt of such consent, Sellers shall convey to
        Purchaser, and Purchaser shall purchase from Sellers, for a price equal
        to the Allocated Value of such Asset and subject to and in accordance
        with the other terms of this Agreement, the Asset to which such consent
        requirement applies. If such outstanding consent is not obtained prior
        to the expiration of one hundred fifty (150) days after the Closing
        Date, and Purchaser has elected to purchase and receive a conveyance of
        the affected Asset at the Closing, Purchaser shall have the right and
        option to reassign the affected Asset to Sellers, without representation
        or warranty as to title except as against those claiming the same by,
        through, or under Purchaser and subject only to those matters to which
        the Asset was subject at Closing, and Sellers shall refund to Purchaser
        the Allocated Value for such Asset subject to adjustment for revenues,
        expenses, and other matters attributable to such Asset since the
        Effective Date in accordance with Section 2.4. Upon such reassignment,
        Sellers shall have no further liability to Purchaser with respect to
        such Asset under this Section 3.10.3.

                               4. CASUALTY LOSS.

4.1 Casualty Loss. If, prior to the Closing, any of the Assets are substantially
damaged or destroyed by fire, explosion, accident, act of the public enemy, act
of God, or other similar event or occurrence ("Casualty Loss"), Sellers shall
notify Purchaser promptly after Sellers learn of such event. Sellers shall have
the right, but not the obligation, to cure any such Casualty Loss by repairing
such damage or, in the case of Personal Property or fixtures, replacing the
damaged Asset with equivalent items no later than the Closing Date. If any
Casualty Loss exists at the Closing, Purchaser shall proceed to purchase the
damaged Assets, and the Purchase Price shall be reduced by the aggregate
reduction in value of all Assets affected by such Casualty Loss ("Casualty Loss
Amount"), as determined by the mutual agreement of the Parties; provided that if
the Parties are unable to agree on such amount prior to the Closing, then such
determination shall be made by the Defect Expert as provided in Section 3.9
above. Each Casualty Loss as to which Sellers and Purchaser reach agreement on
the Casualty Loss Amount prior to the Closing or as to which such Casualty Loss
Amount is finally determined pursuant to Section 3.9 shall be referred to herein
as a "Finally Determined Casualty Loss." Notwithstanding anything to the
contrary contained in this Section 4.1, (i) a reduction of the Purchase Price
attributable to any Casualty Loss shall be made only to the extent permitted
under the provisions of Section 3.5.2, and (ii) if a Casualty Loss does not
result in a reduction of the Purchase Price hereunder, Sellers shall promptly
remit to Purchaser all insurance proceeds and shall take all actions necessary
to permit Purchaser to pursue any claims against third parties, in each case
relating to any such Casualty Loss that is not repaired by Sellers; provided,
however, that if any reduction to the Purchase Price occurs as the result of a
Casualty Loss, Sellers shall be entitled to retain all insurance proceeds and
claims against other parties relating to any such Casualty Loss. For purposes of
this Section 4.1, normal wear and tear shall not be considered a Casualty Loss.

                           5. ENVIRONMENTAL CONDITION

5.1 Physical Condition of the Assets. The Assets have been used for Hydrocarbon
drilling and production operations and various related oil field operations.
Physical changes in or under the Assets or adjacent lands may have occurred as a
result of such uses. The Assets also may contain buried pipelines and other
equipment, whether or not of a similar nature, the locations of which may not
now be known by Sellers or be readily apparent by a physical inspection of the
Assets. Purchaser understands that Sellers do not have the requisite information
with which to determine the exact nature or condition of the Assets or the
effect any such use has had on the physical condition of the Assets. In
addition, Purchaser acknowledges that some oil field production equipment may
contain asbestos and/or naturally occurring radioactive material ("NORM"). In
this regard, Purchaser expressly understands that NORM may affix or attach
itself to the inside of wells, materials, and equipment as scale or in other
forms, and that the wells, materials, and equipment located on the Assets may
contain NORM and that NORM containing materials may be buried or have been
otherwise disposed of on the Assets. Purchaser also expressly understands that
special procedures may be required for the removal and disposal of asbestos and
NORM from the Assets where it may be found.

5.2     Environmental Assessment.

5.2.1   Prior to the Closing, and upon reasonable, prior notice to Sellers,
        Purchaser and any third party environmental consulting firm approved by
        DSX on behalf of Sellers (which consent shall not be unreasonable
        withheld) and retained by Purchaser (the "Purchaser's Environmental
        Consultant"), to the same extent Sellers have such right, shall have the
        right to enter upon the Assets and all buildings and improvements
        thereon, inspect the same, conduct soil and water tests and borings, and
        generally conduct such tests, examinations, investigations, and studies
        as may be necessary or appropriate for the preparation of appropriate
        engineering and other reports, judgments, and environmental assessments
        in relation to the Assets, their environmental condition, and the
        existence of Environmental Defects (as hereinafter defined) (such
        inspection and investigation being called herein "Purchaser's
        Environmental Assessment"). Purchaser shall promptly provide to Sellers
        a copy of Purchaser's Environmental Assessment, including any reports,
        data, and conclusions. Purchaser and Sellers shall keep strictly
        confidential any data or information acquired from such examinations and
        the results of all analyses of such data and information and shall not
        disclose same to any person or Governmental Body without the prior
        written approval of the other Party, except such disclosure as may be
        required by Applicable Law. This obligation of confidentiality shall
        survive the Closing.

5.2.2   WITH RESPECT TO PURCHASER'S ENVIRONMENTAL ASSESSMENT, PURCHASER SHALL
        INDEMNIFY AND HOLD HARMLESS THE SELLERS' GROUP FROM ANY AND ALL COSTS
        ARISING OUT OF OR RESULTING FROM THE ACTS OR OMISSIONS OF PURCHASER OR
        PURCHASER'S ENVIRONMENTAL CONSULTANT IN CONNECTION WITH PURCHASER'S
        ENVIRONMENTAL ASSESSMENT, INCLUDING, WITHOUT LIMITATION, COSTS RELATING
        TO (I) ANY AND ALL STATUTORY OR COMMON-LAW LIENS OR OTHER ENCUMBRANCES
        FOR LABOR OR MATERIALS FURNISHED IN CONNECTION WITH SUCH TESTS,


                                     Page 24


        SAMPLINGS, STUDIES, OR SURVEYS AS PURCHASER OR PURCHASER'S ENVIRONMENTAL
        CONSULTANT MAY CONDUCT WITH RESPECT TO THE ASSETS AND (II) CLAIMS
        ASSERTED BY PURCHASER, ITS AFFILIATES, AND THEIR RESPECTIVE PARTNERS,
        SHAREHOLDERS, MEMBERS, OFFICERS, DIRECTORS, EMPLOYEES, AGENTS AND
        REPRESENTATIVES (COLLECTIVELY, THE "PURCHASER GROUP") FOR INJURY TO OR
        DEATH OF ANY PERSON, PERSONS, OR OTHER LIVING THINGS, OR DAMAGE TO OR
        LOSS OF PROPERTY, IN EITHER CASE RESULTING FROM, ARISING OUT OF, OR
        OCCURRING IN CONNECTION WITH PURCHASER'S ENVIRONMENTAL ASSESSMENT,
        REGARDLESS OF WHETHER SUCH COSTS ARE ATTRIBUTABLE, IN WHOLE OR IN PART,
        TO THE NEGLIGENCE, SOLE OR CONCURRENT, OF THE SELLERS' GROUP.

5.3 Environmental Defect Notice. If Purchaser reasonably determines, as a result
of Purchaser's Environmental Assessment, that there exists or may exist an
Environmental Defect, Purchaser may notify Sellers thereof in writing as soon as
reasonably practical after its discovery, but in any event before the end of the
Due Diligence Period (the "Environmental Defect Notice"). Any notice provided
hereunder shall include appropriate evidence to substantiate Purchaser's
position, including a description of the Environmental Defect, the Environmental
Law applicable to the Environmental Defect, Purchaser's basis for believing that
Sellers is in violation of such Environmental Law, the Well or Wells affected by
the Environmental Defect, an estimate from Purchaser's Environmental Consultant
outlining the cost for Remediation (as hereinafter defined), which estimate
shall identify the methods and scope of the remediation proposed and all
assumptions relied upon by Purchaser's Environmental Consultant in calculating
the estimated cost of Remediation, and a calculation by Purchaser of the
Remediation Amount (as hereinafter defined) attributable to the Environmental
Defect based upon the estimate of Purchaser's Environmental Consultant.
Purchaser will be deemed to have conclusively waived any Environmental Defect
discovered by Purchaser during the Due Diligence Period about which it fails to
notify Sellers in writing prior to the expiration of the Due Diligence Period.

5.4 Remedies for Environmental Defects. For any Environmental Defect properly
asserted by Purchaser during the Due Diligence Period, subject to the
termination rights of both Parties pursuant to Section 3.8, Sellers shall have
the option, in their sole discretion, of (i) remedying the Environmental Defect,
(ii) contesting the Environmental Defect or the Remediation Amount, or (iii)
subject to the terms of Section 5.5.2, reducing the Purchase Price by an amount
equal to the Remediation Amount ("Environmental Indemnity Payment").

5.5 Procedure for Resolving Environmental Defects. With respect to Environmental
Defects properly and timely asserted by Purchaser as provided herein, the
following procedures shall apply.

5.5.1   If Sellers contest the existence of an Environmental Defect or the
        Remediation Amount, Sellers shall provide Purchaser a Rejection Notice
        with respect thereto on or before five (5) days after Sellers' receipt
        of the Environmental Defect Notice. The Rejection Notice shall state


                                     Page 25


        with reasonable specificity the basis of Sellers' rejection of the
        Environmental Defect or the Remediation Amount. No later than five (5)
        days following Purchaser's receipt of the Rejection Notice,
        representatives of Purchaser and Sellers, knowledgeable in environmental
        matters, shall meet and either: (i) agree to mutually reject the
        particular Environmental Defect, or (ii) agree on the validity of such
        Environmental Defect and the Remediation Amount, in which case Sellers
        shall remedy such Environmental Defect at their own expense and to the
        satisfaction of the appropriate Governmental Body prior to the Closing
        or as soon thereafter as is reasonably practicable and, failing such
        remedy, make the Environmental Indemnity Payment therefor, subject to
        the limitation set forth in Section 5.5.2. If the Parties cannot agree
        on either option (i) or (ii) in the preceding sentence, the
        Environmental Defect or the Remediation Amount subject to the Rejection
        Notice shall be submitted to dispute resolution in accordance with the
        procedures set forth in Section 3.9. Each Environmental Defect as to
        which Sellers and Purchaser reach agreement hereunder concerning the
        validity of such Environmental Defect and its Remediation Amount or as
        to which such validity and/or Remediation Amount is finally determined
        pursuant to Section 3.9 shall be referred to herein as a "Finally
        Determined Environmental Defect."

5.5.2   Notwithstanding the provisions of Section 5.5.1, Sellers shall be
        obligated to make an Environmental Indemnity Payment only if, and then
        only to the extent, provided in Section 3.5.2. If Purchaser asserts
        Finally Determined Environmental Defects for which Sellers elect to make
        an Environmental Indemnity Payment, and the sum of the aggregate
        Remediation Amounts for such unremedied Finally Determined Environmental
        Defects plus (ii) the aggregate Defect Values for all uncured Finally
        Determined Title Defects, plus (iii) the aggregate Casualty Loss Amounts
        for all unrepaired Finally Determined Casualty Losses do not exceed the
        Deductible, no Environmental Indemnity Payment shall be made.

5.6 Definitions. For purposes of this Agreement, the following expressions and
terms will have the meanings set forth hereinafter:

5.6.1   "Applicable Laws" shall mean all laws, statutes, treaties, rules, codes,
        ordinances, regulations, certificates, orders, interpretations, licenses

        and safety, consumer product safety, employee benefits, the environment,
        securities or zoning) and all judgments, decrees, injunctions, writs,
        orders, or like action of any court, arbitrator, or other Governmental
        Body of competent jurisdiction.

5.6.2   "Environmental Defect" shall mean a condition that exists prior to the
        Effective Date, and only to the extent in existence as of the Effective
        Date, with respect to the air, land, soil, surface, subsurface strata,
        surface water, ground water or sediments which causes an Asset to be
        subject to definitive remediation within a time certain under
        Environmental Laws in effect as of the Effective Date, but only to the
        extent that (i) the condition was not otherwise known to Purchaser prior
        to the execution of this Agreement, and (ii) the Remediation Amount, net
        to Purchaser's interest, will exceed the sum of $50,000.

        associated with Plugging and Abandonment (as hereinafter defined). The
        terms "hazardous substance", "release", and "threatened release" shall
        have the meanings specified in CERCLA; provided, however, that to the
        extent the laws of the state in which the Assets are located are
        applicable and have established a meaning for "hazardous substance",
        "release", "threatened release", "solid waste", "hazardous waste", and
        "disposal" that is broader than that specified in CERCLA or RCRA, such
        broader meaning shall apply with respect to the matters covered by such
        laws.

        environmental remedies to the extent required by Environmental Laws in
        effect as of the Effective Date to remedy an Environmental Defect
        existing on or with respect to an Asset using the least stringent, most
        cost effective standard, but only to the extent such requirement relates
        to the continued use and operation of the Asset for Hydrocarbon
        exploration, production, and gathering.

other Seller, and severally according to its ownership interests in the Assets
and not jointly or collectively, represents and warrants to Purchaser, as of the

        other action of each Seller and will not violate or be in conflict with,
        or result in a breach, or trigger a default (or an event that, with the

        default) under the provisions of, (i) any material note, bond, mortgage,
        indenture, Lease contract (including the Existing Contracts), agreement,

        Purchaser, its ownership or operation, after the Closing, of any of the
        Assets, or the ability of any Seller to consummate the transactions
        contemplated herein. This Agreement has been, and the other documents

        or otherwise, for brokers' or finders' fees relating to the matters
        provided for in this Agreement which will be the responsibility of
        Purchaser. Any such obligation or liability of any Seller shall be the
        sole obligation of such Seller.

6.2.5   Certain Tax Matters. Each Seller has filed all tax returns that it was
        required to file and has paid all taxes shown thereon as owing or
        subsequently assessed with respect thereto. The agreements to which the
        Properties are subject do not create, for federal income tax purposes, a
        partnership among any of the parties to such agreements for which a
        partnership income tax return is required to be filed under Subchapter K
        of Chapter 1 of Subtitle A of the IRC (other than a partnership for
        which an election is in effect pursuant to the provisions of Section 761
        of the IRC and the regulations thereunder to be excluded from such
        provisions).


                                     Page 29


6.2.6   Pending Claims and Litigation. There are no suits, actions or other
        legal, administrative, or arbitration proceedings that are pending or,
        to each Seller's knowledge, threatened in writing against any Seller,
        KEBO, or any of the Assets that would, if determined adversely to
        Sellers, (i) result in the material impairment or loss of Sellers' title
        to the relevant Assets, (ii) materially hinder or impede the operation
        of all or any material portion of such Assets, or (iii) that would, if
        determined adversely to the Parties, restrain, prohibit, or impose
        damages on Purchaser or Sellers with respect to, or otherwise materially
        impair Sellers' ability to consummate, the transactions contemplated by
        this Agreement.

6.2.7   Preferential Rights; Required Consents. Except as otherwise reflected in
        Exhibit D, none of the Leases or Existing Contracts is subject to a
        preferential right to purchase, third party consent to assignment
        requirement, right of first refusal, or right of first offer.

6.2.8   Governmental Approvals. Except for approvals by Governmental Bodies
        customarily obtained after the Closing, no authorization, consent,
        approval, exemption, franchise, permit, or license of, or filing with,
        any Governmental Body is required to authorize, or is otherwise required
        by any Governmental Body in connection with, the valid execution and
        delivery by Sellers of this Agreement, the transfer of the Assets by
        Sellers to Purchaser, or the performance by Sellers of their other
        obligations hereunder.

6.2.9   Leases. To each Seller's knowledge, each Lease is in full force and
        effect. Each Seller has, in all material respects, fulfilled all
        requirements for filings, certificates, consents, approvals,
        disclosures, and similar matters contained in the Leases and Applicable
        Law, and each Seller is fully qualified to own, operate, and transfer
        the Leases under the terms thereof and Applicable Law. No Seller is in
        material breach or material default, and there has occurred no event,
        fact, or circumstance that, with the lapse of time or the giving of
        notice, or both, would constitute such a material breach or material
        default by any Seller, with respect to any terms of any Lease. No lessor
        under any Lease has given or, to any Seller's knowledge, threatened to
        give notice of any action to terminate, cancel, rescind, repudiate, or
        procure a judicial reformation of any Lease or any provision thereof.

6.2.10  Payments Under the Leases. To each Seller's knowledge, such Seller has
        correctly made, or caused to be correctly made, all payments, including,
        without limitation, royalties, rentals, shut-in well payments, and other
        lease maintenance payments, due in respect of the Leases thereunder and
        required to be made by such Seller.

6.2.11  Gas Imbalances. Except for those listed on Exhibit G, there exist no
        production imbalances or imbalances with respect to any pipeline,
        storage, or processing facility or other conditions regarding
        Hydrocarbons taken or marketed from the Assets or any portion thereof
        which could result in:

        (a)    a portion of the interest of Sellers in such Hydrocarbon
               production being taken or delivered after the Closing without
               Purchaser then receiving payment therefor or at the price it
               would have received absent such imbalance; or


                                     Page 30


        (b)    Sellers being obligated to make payment to any person or entity
               as a result of such imbalance; or

        (c)    Sellers being obligated, by virtue or any prepayment arrangement,
               take-or-pay agreement, or similar arrangement, to deliver
               Hydrocarbons produced from the Assets at some future time without
               then receiving full payment therefor.

Notwithstanding anything else to the contrary contained herein, Purchaser's sole
and exclusive remedy with respect to any breach of the representation and
warranty contained in this Section 6.2.11 shall be an adjustment to the Purchase
Price at the Closing.

6.2.12  Existing Contracts. Except for those contracts for the sale of
        Hydrocarbons which are terminable within thirty-one (31) days or less,
        to Sellers' knowledge, Exhibit C contains a complete list of all
        contracts and agreements that constitute the Existing Contracts. With
        respect to the Existing Contracts: (i) to each Seller's knowledge, all
        Existing Contracts are in full force and effect; (ii) no Seller is in
        material breach or material default, and there has occurred no event,
        fact, or circumstance that, with the lapse of time or the giving of
        notice, or both, would constitute such a material breach or material
        default by any Seller, with respect to the terms of any Existing
        Contract; (iii) to each Seller's knowledge, no party to an Existing
        Contract is in material breach or material default with respect to the
        terms of any Existing Contract; and (iv) no Seller or, to each Seller's
        knowledge, any other party to an Existing Contract has given or
        threatened to give notice of any action to terminate, cancel, rescind,
        or procure a judicial reformation of such Existing Contract or any
        provision thereof.

6.2.13  Compliance With Applicable Laws. Except as set forth on Exhibit F, each
        Seller, to its knowledge, has complied in all material respects with all
        Applicable Laws relating to the Assets or the use, ownership, or
        operation thereof (other than Environmental Laws, which are governed by
        Article 5, and laws related to taxes, as to which Sellers' sole
        representations and warranties are set forth in Section 6.2.5). Each
        Seller has all governmental permits required in connection with the
        ownership and operation of the Assets; has properly made all filings
        necessary or appropriate to obtain such governmental permits; and all of
        such governmental permits and filings are in full force and effect. No
        Seller has received notice from any Governmental Body or other person
        that any such Applicable Law, governmental permit, or filing has been
        violated or not complied with in any material respect with respect to
        the Assets by Sellers.

6.2.14  Wells. As of the date of this Agreement, the Wells described on Exhibit
        B are the only wells currently capable of producing Hydrocarbons located
        on the Properties. All of such Wells have been, or will be, drilled,
        completed, and operated within the boundaries of the relevant Leases or
        within the limits otherwise permitted by contract and by Applicable Law
        and in compliance with the provisions of the applicable Leases, Existing
        Contracts, and all Applicable Laws. The production of Hydrocarbons from
        such Wells has not been in excess of the allowable production
        established for each Well. All Hydrocarbon wells located on the Leases
        that have permanently ceased the production of Hydrocarbons in paying
        quantities, as well as all plants, pipelines, personal property, pits,
        equipment, materials, appurtenances, and facilities located on or used
        in connection with the Properties and that Sellers have abandoned or


                                     Page 31


        otherwise permanently ceased to use, have been plugged and/or abandoned,
        and all related salvage, site clearance, and surface restoration
        operations have been completed, in accordance with Applicable Laws, and
        all costs and expenses incurred in connection therewith have been paid
        in full. None of the Wells has been plugged and abandoned.

6.2.15  Hydrocarbon Marketing. Except as identified in Exhibit C, there are no
        calls on production, options to purchase, or similar rights in effect
        with respect to any portion of the Hydrocarbons allocable to the Assets,
        and all contracts for the sale of Hydrocarbons produced from the Assets
        are terminable without penalty on no more than thirty (30) days' prior
        notice. Each Seller is currently receiving the prices provided for under
        such sales contracts with respect to the Hydrocarbons. All proceeds from
        the sale of Hydrocarbons attributable to the interests in the Assets of
        each Seller have been and are being disbursed to such Seller under
        appropriate division orders, transfer orders, or similar documents
        signed by or otherwise binding on such Seller, and no portion of any
        such proceeds is being held in suspense, subject to a claim for refund
        by the purchaser, used as an offset or as collateral for other
        obligations (whether disputed or undisputed), or otherwise not being
        paid to any Seller as it becomes due in the ordinary course of business.

6.2.16  Payment of Expenses; Commitments. Each Seller has paid its respective
        proportionate share of all amounts owed by Sellers in connection with
        the Assets for which Sellers have received invoices from the operator(s)
        thereof, and there are no outstanding calls or payments due from any
        Seller under the terms of the Existing Contracts or otherwise with
        respect to the Assets. Exhibit H contains a true and complete list and
        description, as of the date of execution of this Agreement, of all
        authorities for expenditures, plans of exploration and/or development,
        and other commitments as to which Sellers have become obligated
        regarding drilling, reworking, or other operations or other capital
        expenditures on or relating to the Assets which were not completed prior
        to the date of this Agreement. There are no express obligations to drill
        additional Hydrocarbon wells or engage in other operations on the
        Properties that are binding on any Seller, except as identified on
        Exhibit H and except for drilling obligations arising under offset well
        provisions of, or implied covenants under, the Leases, and operations
        proposed under the Existing Contracts that allow the parties thereto to
        elect whether to participate. There are no material operations on the
        Assets with respect to which any Seller has become a non-consenting
        party.

6.2.17  Areas of Mutual Interest, Etc. Except as set forth in any agreement
        identified or referred to in Exhibit A or C, the Assets are not subject
        to any contract containing an area of mutual interest, maintenance of
        uniform interest, "before payout" or "after payout" reversion or
        conversion, or other provision under which Sellers or Purchaser may be
        obligated to make assignments to third Persons of interests in any Asset
        after the Effective Time.

6.2.18  No Bankruptcy. There are no bankruptcy, insolvency, reorganization, or
        arrangement proceedings pending, being contemplated by, or, to each
        Seller's knowledge, threatened against any Seller or any Affiliate that
        controls any Seller.


                                     Page 32


6.2.19  Insurance. Each Seller has paid all premiums required under, and is
        otherwise in compliance with, the terms of all insurance policies or
        self-insurance programs obtained by Sellers with respect to the Assets,
        all of which policies or programs, or renewals thereof, are as of the
        date of execution of this Agreement, in full force and effect.

6.3 Knowledge. As used in this Agreement, words "to each Sellers' knowledge,"
"to the knowledge of Sellers," or other words of similar import mean that the
statement so qualified is true to the actual present awareness of the relevant
Seller if an individual, or to the actual present awareness of the responsible
executive officers or trustees of such Seller, if a corporation, partnership,
limited liability company, trust, or other entity.

                     8. PRE-CLOSING OBLIGATIONS OF SELLERS

8.1 Operations. From the date of this Agreement until the Closing Date (the
"Interim Period"), Sellers shall continue to operate the Properties the same as
a reasonable and prudent operator and in accordance with the terms and
conditions of the Leases, the Existing Contracts, and all Applicable Laws.
However, Sellers will have no obligation to operate any portion of the
Properties after the expiration of the Interim Period except as provided for in
Section 8.3. During the Interim Period, Sellers will maintain, or cause to be
maintained, the lease equipment in the same condition, working order, and state
of repair as currently exists, subject to ordinary wear and tear. During the
Interim Period and thereafter until operations are transferred to Purchaser,
without the prior written consent of Purchaser, Sellers will (i) cause the
Properties to be developed, maintained or operated in a manner substantially
consistent with prior operations, (ii) not abandon any part of the Properties,
(iii) not commence any operation on any Property anticipated to cost, as to the
aggregate interests of Sellers in the relevant Property, in excess of
$100,000.00 per operation, except emergency operations, operations required
under presently existing contractual obligations, the on-going commitments under
the AFE's described in Exhibit H, and operations undertaken to avoid any penalty
provision of any Existing Contract or order (with respect to emergency
operations, Sellers shall notify Purchaser of said emergency as soon as
reasonably practical), (iv) timely pay and discharge, or cause to be timely paid
and discharged, when due all costs and expenses incurred in connection with the
Properties and otherwise keep the Properties free of liens and encumbrances that
do not constitute Permitted Encumbrances, and (v) not mortgage, pledge,
encumber, dedicate, sell, convey or dispose of any part of the Assets (other
than the sale of Personal Property replaced with items of comparable or superior
quality and the sale of Hydrocarbons produced from the Properties in the
ordinary course of business).

8.2 Contracts. During the Interim Period, Sellers will not, without the prior
written consent of Purchaser, enter into any agreement amending, modifying, or
terminating any of the Leases or any of the Existing Contracts.

8.3 Compensation of Operator. KEBO shall operate the Properties for the benefit
of Purchaser during the period from the Effective Date through the date(s) after
the Closing when the operation of such Properties is turned over to, and becomes
the responsibility of, Purchaser (the "Operations Period"). In the absence of an
applicable operating agreement, for any such services as operator performed by
KEBO during the Operations Period, KEBO shall be entitled to receive from
Purchaser, in accordance with the 2005 COPAS Onshore Model Accounting Procedure,
which is hereby incorporated by reference, all reasonable and necessary expenses
incurred by KEBO in operating, protecting, and maintaining the Properties, and
an overhead charge of $500.00 per month per operated Well. Any such charges and
expenses shall be recovered by KEBO as part of the Closing or post-Closing
adjustments, as appropriate. KEBO will have no obligation to make capital
expenditures or extraordinary operating expenditures in connection with the
Properties during the Operations Period. Upon the expiration of the Operations
Period, Purchaser will additionally reimburse KEBO for the amounts of any unpaid


                                     Page 35


operating expenses and capital expenditures of other working interest owners
paid by KEBO and attributable to operations during the Operations Period. KEBO
will be entitled to retain any overhead payments received from other working
interest owners and attributable to operations during the Operations Period.

8.4 Permissions. During the Interim Period, Sellers shall use reasonable efforts
to obtain all permissions, approvals, and consents by Federal, state and local
governmental authorities and others as may be required to consummate the
transactions contemplated by this Agreement (excluding governmental permissions,
approvals and consents which are customarily obtained after the assignment of an
oil and gas interest, which shall be the responsibility of Purchaser to obtain).

8.5 Efforts. Sellers will use its reasonable commercial efforts to cause its
representations and warranties set forth in Article 6 to be true and correct on
and as of the Closing Date.

8.6 Defaults. Sellers shall give prompt written notice to Purchaser of any
notice of material default (or written threat of material default, whether
disputed or denied by Sellers) received or given by Sellers subsequent to the
Effective Date under any Lease or Existing Contract.

8.7 Operatorship. On the Closing Date, except as otherwise provided in Section
8.3, Sellers shall cause KEBO to resign as operator of all of the Properties.
With respect to those Properties as to which Sellers own a sufficient share of
the Working Interest to control the selection of the successor operator, at the
Closing, Sellers shall deliver to Purchaser a written notification designating
Purchaser as the successor operator of such Properties, effective as of the
Closing Date. With respect to those Properties (if any) as to which Sellers do
not own a sufficient share of the Working Interest to control the selection of
the successor operator, Sellers will cast their votes, and will use reasonable
commercial efforts to obtain, prior to the Closing, the votes of the other
owners of interests in the relevant Properties, in each case in favor of the
designation of Purchaser as successor operator of such Properties, effective as
of the Closing Date. Within five (5) business days after the later of the
Closing Date or the date on which Purchaser is named successor operator under
the terms of the applicable Existing Contract, Sellers and Purchaser shall make
all necessary filings and take all other actions necessary to cause the
resignation of KEBO as operator and Purchaser's designation as the successor
operator of each Property to be recognized and, if required, approved by all
relevant Governmental Bodies. In each case, Sellers shall use reasonable
commercial efforts to assist Purchaser in assuming the timely operation and
management of the Properties.

8.8 Geological and Geophysical Information. During the Interim Period, with
respect to any right, title, and interest of Sellers in any Technical Data:

8.8.1   Sellers shall use reasonable commercial efforts to determine whether
        each item of Technical Data is subject to a contractual restriction on
        transfer or confidentiality obligation (including, without limitation,
        contacting appropriate parties in cases where Sellers' files are not
        clear in this regard).

8.8.2   Sellers shall use reasonable commercial efforts to obtain consents or
        waivers of any such contractual restriction on transfer or
        confidentiality obligation, but in no event shall Sellers be required to


                                     Page 36


        make any payment to the holder(s) of such right to obtain such waiver or
        consent.

8.8.3   At the Closing, Sellers shall assign and deliver possession to Purchaser
        of all Technical Data for which required waivers or consents have been
        obtained.

8.8.4   Sellers shall retain at Closing all Technical Data for which required
        waivers or consents have not been obtained.

8.9 Financial Statements. During the Interim Period, Sellers shall promptly
furnish and make available to Purchaser and its auditors all books, records,
invoices, reports and other data pertaining to the Assets (collectively, the
"Work Papers") for (i) the calendar years ended December 31, 2004, 2005, and
2006, and (ii) for the six (6) months ended June 30, 2007. Purchaser and its
auditors shall utilize the Work Papers to prepare, at Purchaser's sole expense,
an audited Statement of Combined Revenues and Direct Lease Operating Expenses
for the years ended December 31, 2004, 2005, and 2006, and an unaudited
Statement of Combined Revenues and Direct Lease Operating Expenses for the six
(6) months ended June 30, 2007 (collectively, the "Financial Statements").
Sellers agrees to make reasonable efforts to assist and cooperate with Purchaser
in the timely preparation of the Financial Statements, provided such assistance
and cooperation do not interfere with Sellers' ongoing business activities nor
cause Sellers to incur any expense related thereto. SELLERS MAKES NO
REPRESENTATIONS OR WARRANTIES WITH RESPECT TO THE ACCURACY OR COMPLETENESS OF
THE WORK PAPERS OR ANY PORTION THEREOF, AND PURCHASER EXPRESSLY ACKNOWLEDGES

and ending on a date that is ten (10) Business Days thereafter (the "Report
Period"), Purchaser, at Purchaser's sole cost and expense, shall cause Cawley,
Gillespie & Associates, Inc., to prepare a reserve and economic evaluation of
the Properties in accordance with the parameters set forth hereinafter (the
"Cawley, Gillespie Reserve Report") in form and substance satisfactory to
Purchaser in its sole discretion. Purchaser shall obtain from Cawley, Gillespie

reserve reporting requirements of the Securities Exchange Commission ("SEC")
under applicable securities laws and regulations, and (iii) will employ
SEC-mandated assumptions concerning commodity prices, determined as of December
31, 2006. Sellers have previously provided to Purchaser a full and complete copy
of the Lenser Reserve Report. Promptly after the Participation Period, Sellers
shall make available to Purchaser for review and/or copying all notes,
calculations, pressure data, P/Z curves, decline curves, geological maps,
geophysical data, lease and ownership data, capital expenditure and lease
operating expense data, property tax information, and other data and information
utilized by R. A. Lenser & Associates in the preparation of the Lenser Reserve
Report. Sellers shall also use reasonable commercial efforts to provide
Purchaser with access to the personnel of R. A. Lenser & Associates who
participated in the preparation of the Lenser Reserve Report. If the Cawley,


                                     Page 37


Gillespie Reserve Report is completed within the Report Period, and the
estimated total proved Hydrocarbon reserves assigned to the Properties by the
Cawley, Gillespie Reserve Report are less than 40,000 MMCFE for the Net Revenue
Interest attributable to one hundred percent (100%) of the Working Interest in
the Properties, Purchaser shall have the right, exercisable no later than two
(2) Business Days after Purchaser's receipt of the Cawley, Gillespie Reserve

period from the date of Purchaser's receipt of the Cawley, Gillespie Reserve
Report through the expiration of the second (2nd) Business Day after the date on
which Purchaser receives the Cawley, Gillespie Reserve Report shall be referred
to herein as the "Reserve Option Period." If this Agreement is properly
terminated by Purchaser during the Reserve Option Period pursuant to this
Section 8.10, Purchaser shall be entitled to the return of the Performance
Deposit, less and except the sum of Two Hundred Thousand and No/100's Dollars
($200,000.00) which is to be retained by Sellers, and neither Sellers nor
Purchaser shall have any further obligation or liability to the other Party
under this Agreement or otherwise in connection with the transactions
contemplated herein, subject, however, to the terms of Section 14.2. In such
event, Purchaser agrees to destroy the Cawley, Gillespie Reserve Report (and all
copies of such report in Purchaser's possession), and to refrain from disclosing
such report or any of its contents to any third party.

8.11 Exclusive Dealing. From and after the date Purchaser delivers the
Performance Deposit as contemplated herein, and unless and until the Closing
occurs or this Agreement is terminated, no Seller, and no partner, officer,
director, manager, employee, trustee, agent, or representative of any Seller,
shall directly or indirectly solicit, encourage, or entertain any offers from,
or negotiate with, or in any manner encourage, discuss, accept, or consider, any
proposal of any other person relating to the sale of the Assets. Each Seller
shall immediately disclose to Purchaser any contact between any Seller or its
partners, officers, directors, managers, employees, trustees, agents, or
representatives and any other person regarding any such offer, proposal, or
related inquiry.

        counterparts of the Assignment, Bill of Sale and Conveyance in

        After the Closing Date, Purchaser shall be responsible for proper
        distribution of all the suspended funds to the parties lawfully entitled
        thereto, and Purchaser agrees to indemnify and hold Sellers and the
        Sellers Group harmless from and against any Costs associated with
        Purchaser's receipt and distribution of such suspended funds, but only

12.5.8  Sellers shall deliver to Purchaser the notices and documents required to

according to its ownership interest in the Wells and not jointly, shall warrant
and agree to defend the title to such Seller's interests in the Wells against
the lawful claims and demands of all persons claiming the same, or any part
thereof, but limited to such claims arising by, through, or under such Seller
and not otherwise, and shall be made subject to and excepting all Permitted
Encumbrances.

                          13. POST-CLOSING OBLIGATIONS

13.1    Post-Closing Adjustments.

13.1.1  As soon as reasonably practicable after the Closing, but in no event
        later than one hundred twenty (120) days after the Closing Date, Sellers
        shall prepare, in accordance with this Agreement, and deliver to
        Purchaser, a statement setting forth each adjustment to the Purchase
        Price made pursuant hereto (the "Post-Closing Adjustment Statement").
        The Post-Closing Adjustment Statement will include any adjustments
        necessary in connection with any changes in the gas imbalances, as of
        the Effective Date, from those set forth in Exhibit G as determined in
        accordance with Section 13.1.3, and any other adjustments required under
        the provisions of Section 2.4. As soon as reasonably practicable, but in
        no event later than thirty (30) days after Purchaser's receipt of the
        Post-Closing Adjustment Statement from Sellers, Purchaser shall deliver
        to Sellers any objections that Purchaser has to the Post-Closing
        Adjustment Statement. If Purchaser fails to object to such Post-Closing
        Adjustment Statement within such thirty (30) day time period, the
        Post-Closing Adjustment Statement shall be conclusively deemed to be
        final and accepted by both Parties. The Parties shall undertake to agree
        on the final Adjusted Purchase Price no later than one hundred eighty
        (180) days after the Closing. If Purchaser and Sellers are unable to
        agree upon the adjustments in the Post-Closing Adjustment Statement
        within one hundred eighty (180) days after the Closing, the Accounting
        Firm shall conduct an audit of the Post-Closing Adjustment Statement and
        determine the post-Closing adjustment amount. The decision of the
        Accounting Firm shall be binding upon Sellers and Purchaser, and the
        fees and expenses of such Accounting Firm shall be borne one-half by
        Sellers and one-half by Purchaser.

13.1.2  The date upon which agreement is reached on the Adjusted Purchase Price
        shall be called herein the "Final Settlement Date." Within five (5)
        business days after the Final Settlement Date, those credits agreed upon
        by Purchaser and Sellers shall be netted, and the final settlement shall
        be paid in cash by the Party owing same, via wire transfer as directed
        in writing by the receiving Party.

13.1.3  If either Party determines, prior to the delivery of the Post-Closing
        Adjustment Statement, that Hydrocarbon production imbalances or
        imbalances with respect to any pipeline, storage, or processing facility


                                     Page 42


        attributable to Wells included in the Assets as of the Effective Date
        are other than as set forth in Exhibit G, subject to verification of the
        other Party, the Purchase Price shall be adjusted upward or downward in
        connection with the Post-Closing Adjustment Statement, depending upon
        whether there is a net overproduction or a net underproduction
        attributable to such Wells. The amount to be paid by Purchaser to
        Sellers with respect to any underproduction, or by Sellers to Purchaser
        with respect to any overproduction, shall be the present value of the
        net cash flow attributable to all such volumes of gas recoverable
        without cash balancing as determined by an independent registered
        petroleum engineer mutually selected by DSX and Purchaser (the
        "Imbalance Engineer") using (i) an agreed upon pricing index, (ii) an
        annual discount rate of ten percent (10%), and (iii) the maximum rate of
        recovery permitted under the applicable balancing agreements. Upon the
        final determination of the quantity of overproduction and/or
        underproduction attributable to a Well as of the Effective Date, the
        Parties will submit all relevant information to the Imbalance Engineer
        for valuation as described above.

13.2 Receipts and Credits. Except as otherwise provided in this Agreement, all
monies, proceeds, receipts, credits, and income attributable to the Assets for
all periods of time on and after the Effective Date shall be the sole property
of Purchaser, and, to the extent received by Sellers after the Closing, Sellers
shall fully disclose, account for, and transmit the same promptly to Purchaser.
Except as otherwise provided in this Agreement, all monies, proceeds, receipts,
credits, and income attributable to the Assets for all periods of time prior to
the Effective Date shall be the sole property of Sellers, and, to the extent
received by Purchaser after the Closing, Purchaser shall fully disclose, account
for, and transmit the same promptly to Sellers. Except as otherwise provided in
this Agreement, all costs, expenses, and disbursements attributable to the
Assets for periods of time prior to the Effective Date, regardless of when due
or payable, shall be the sole obligations of Sellers, and Sellers shall promptly
pay, or if paid by Purchaser, promptly reimburse Purchaser for, and each Seller,
severally according to its ownership interests in the Assets and not jointly,
shall indemnify and hold Purchaser and its successors and assigns harmless from
and against, the same. Except as otherwise provided in this Agreement, all
costs, expenses, disbursements, obligations, and liabilities attributable to the
Assets for periods of time on and after the Effective Date, regardless of when
due or payable, shall be the sole obligation of Purchaser, and Purchaser shall
promptly pay, or if paid by Sellers, promptly reimburse Sellers for, and
indemnify and hold Sellers and their respective successors and assigns harmless
from and against, the same.

13.3    Assumption and Indemnification.

13.3.1  If the Closing occurs, and except for matters relating to taxes, which
        are governed exclusively by Article 15, the indemnities provided by each
        Party to the other Party under Section 13.3 hereof (i) shall constitute
        the sole and exclusive remedy for such Party with respect to the
        inaccuracy in or breach of any representation or warranty made by the
        other Party hereunder and (ii) in addition to the indemnities contained
        in Sections 3.1, 5.2.2, 12.5.2, 13.2, and 16.8, shall constitute the
        sole and exclusive remedy for such Party with respect to the breach or
        default in the performance by such other Party of any covenant or
        agreement of such other Party under this Agreement, and each Party
        hereby waives any claim or cause of action that it may otherwise have


                                     Page 43


        under common law, any statute, or otherwise against the other Party
        arising from or out of any such breach, inaccuracy, or default.

13.3.2  All representations, warranties, covenants, agreements, and indemnities
        of Purchaser and Sellers shall survive the Closing and the delivery of
        the General Assignment shall not be merged with or into the General
        Assignment and shall remain in force and effect as provided in Section
        13.3.3. Such survival does not obligate any Party to make any further
        representation or warranty after the Closing Date, or to cause any
        representation or warranty made hereunder to remain true and correct
        after the Closing Date.

13.3.3  Except to the extent otherwise provided in Article 15 with respect to
        taxes, neither Purchaser nor Sellers shall be entitled to seek
        indemnification from the other Party with respect to the inaccuracy in
        or breach of any representation or warranty made by such Party hereunder
        unless the Party seeking indemnification gives written notice of the
        alleged inaccuracy or breach to the Party from whom indemnification is
        sought no later than the 365th day after the Closing Date. Except to the
        extent otherwise provided in Article 15 with respect to taxes, and
        except as provided hereinafter, neither Purchaser nor Sellers shall be
        entitled to seek indemnification from the other Party with respect to
        the breach or default in the performance by such Party of any covenant
        or agreement of such Party contained in this Agreement unless the Party
        seeking indemnification gives written notice of the alleged breach or
        default to the Party from whom indemnification is sought no later than
        the 365th day after the Closing Date. Except as provided hereinafter,
        Purchaser shall not be entitled to seek indemnification from any Seller
        under the terms of clause (a) or clause (b) of Section 13.3.6 unless
        Purchaser gives written notice of the claim for indemnification to
        Sellers no later than the 365th day after the Closing Date.
        Notwithstanding the preceding provisions of this Section 13.3.3, there
        shall be no time limitation on the right of a Party entitled to
        indemnification to assert its claim for indemnification or other rights
        arising under Sections 3.1, 5.2.2, 12.5.2, 13.2, or 16.18, or clauses
        (a), (b), or (c) of Section 13.3.5, or clause (a)(1) or clause (c) of
        Section 13.3.6. The deadlines for asserting claims for indemnification
        specified in the preceding two sentences of this Section 13.3.3 shall be
        referred to herein as the "Survival Dates." Except as otherwise provided
        in this Agreement, the sole and exclusive remedies of Purchaser with
        respect to Title Defects, Casualty Losses, and Environmental Defects
        shall be as stated in Articles 3, 4, and 5, and in no event shall any
        other provision of this Agreement entitle Purchaser to any other remedy
        with respect to Title Defects, Casualty Losses, or Environmental
        Defects.

13.3.4  If the Closing occurs, Purchaser shall assume and agrees to pay,
        perform, and discharge any and all Assumed Obligations (as hereinafter
        defined). As used herein, "Assumed Obligations" means all liabilities,
        responsibilities, duties, and obligations that arise from or relate to
        the ownership, use, or operation of the Assets and the production and
        marketing of Hydrocarbons therefrom occurring on or after the Effective
        Date (or, where specifically indicated, the Closing Date), including,
        without limitation: (i) Plugging and Abandonment (as hereinafter
        defined); (ii) any contracts or agreements affecting the Assets in
        existence as of the Effective Date and the Closing Date, including, but
        not limited to, the Existing Contracts; (iii) the Environmental
        Obligations (as hereinafter defined), (iv) ALL CLAIMS AND LIABILITIES


                                     Page 44


        FOR INJURY TO OR DEATH OF ANY PERSON, PERSONS, OR OTHER LIVING THINGS,
        OR LOSS OR DESTRUCTION OF OR DAMAGE TO PROPERTY AFFECTING OR RELATING TO
        THE ASSETS, REGARDLESS OF WHETHER SUCH CLAIM OR LIABILITY RESULTS, IN
        WHOLE OR IN PART, FROM THE NEGLIGENCE OR STRICT LIABILITY OF SELLERS OR
        ANY MEMBER OF THE SELLERS' GROUP, TO THE EXTENT THAT SUCH CLAIM OR
        LIABILITY, OR THE ACTS, OMISSIONS, EVENTS, OR CONDITIONS GIVING RISE
        THERETO, AROSE, OCCURRED, OR EXISTED ON OR AFTER THE CLOSING DATE; (v)
        imbalances due to overproduction of gas by Sellers or the Other Owners
        or pipeline imbalances owed by Sellers under transportation agreements,
        subject, however, to the provisions of Section 13.1.3 hereof; and (vi)
        obligations otherwise assumed by Purchaser under this Agreement. As used
        herein, "Environmental Obligations" means, except for any cost or claim
        resulting from or arising out of the circumstances described in Section
        13.3.6(b), any claim, obligation, or liability relating to the
        environmental condition of the Assets, regardless of whether resulting
        from acts, omissions, events, or conditions occurring before, on, or
        after the Effective Date, including, without limitation: (t) all
        Environmental Defects timely and properly asserted by Purchaser pursuant
        to Article 5, regardless of whether Purchaser receives an Environmental
        Indemnity Payment with respect thereto (it being understood that neither
        Purchaser's assumption of responsibility for such Environmental Defect
        nor Purchaser's indemnity with respect thereto under Section 13.3.5
        shall affect Purchaser's right to receive such an Environmental
        Indemnity Payment hereunder); (u) any other environmental pollution or
        contamination with respect to the air, land, soil, surface, subsurface
        strata, surface water, ground water, or sediments; (v) the failure of
        any Asset to be in compliance, or the owner or operator of the Assets to
        comply, in all material respects with all applicable Environmental Laws,

13.4 Disclaimer. PURCHASER'S OBLIGATIONS UNDER SECTION 13.3.4 AND THE
OBLIGATIONS OF THE INDEMNIFYING PARTY UNDER SECTIONS 13.3.5 AND 13.3.6 SHALL
APPLY REGARDLESS OF THE FAULT OR NEGLIGENCE (OTHER THAN THE GROSS NEGLIGENCE OR
WILLFUL MISCONDUCT) OF THE OTHER PARTY, INCLUDING STRICT OR STATUTORY LIABILITY
OF THE OTHER PARTY UNDER ANY APPLICABLE LAW.

13.5 Method of Asserting Claims. All claims for indemnification under this
Agreement shall be asserted and resolved as follows; provided that the
provisions of Sections 13.5 and 13.6 shall be covenants and not conditions to
the defense and indemnity obligations to which they apply:

13.5.1  If any claim is asserted, whether by a third party (a "Third Party
        Claim") or by the other Party hereto (a "Non-Third Party Claim"), for
        which a Party providing indemnification (the "Indemnifying Party") would
        be liable to a Party or any of its officers, directors, employees,
        agents or representatives entitled to indemnification hereunder
        (collectively, the "Indemnified Party"), the Indemnified Party shall
        promptly notify the Indemnifying Party of such claim, specifying the
        nature of such claim and the amount or the estimated amount thereof to
        the extent then feasible (which estimate shall not be conclusive of the
        final amount of such claim) (the "Claim Notice").


                                     Page 47


13.5.2  Upon its receipt of a timely Claim Notice for a Third Party Claim, the
        Indemnifying Party shall have thirty (30) days from its receipt of such
        Claim Notice (the "Notice Period") to notify the Indemnified Party (i)
        whether it disputes its liability to the Indemnified Party hereunder
        with respect to such Third Party Claim; and (ii) if it does not dispute
        such liability, whether it desires, at its sole cost and expense, to
        defend the Indemnified Party against such Third Party Claim; provided,
        however, that the Indemnified Party is hereby authorized, prior to and
        during the Notice Period, to file any motion, answer, or other pleading,
        submission or document which it shall deem necessary or appropriate to
        protect its interests. If the Indemnifying Party notifies the
        Indemnified Party within the Notice Period that it does not dispute such
        liability and desires to defend against such Third Party Claim, then,
        except as hereinafter provided, the Indemnifying Party shall have the
        right to defend such Third Party Claim by appropriate proceedings, which
        proceedings shall be promptly settled or prosecuted to a final
        conclusion, in such a manner as to avoid any risk of the Indemnified
        Party becoming subject to liability. If the Indemnified Party desires to
        participate in, but not control, any such defense or settlement, it may
        do so at its own cost and expense. If the Indemnifying Party disputes
        its liability with respect to such Third Party Claim, or elects not to
        defend such Third Party Claim, whether by not giving timely notice as
        provided above or otherwise, the Indemnified Party shall have the right,
        but not the obligation, to defend against such Third Party Claim, and
        the amount of any such Third Party Claim, or if the same be contested by
        the Indemnifying Party or by the Indemnified Party, then that portion
        thereof as to which such defense is unsuccessful, shall be conclusively
        deemed to be a liability of the Indemnifying Party hereunder.

13.5.3  Upon receipt of a timely Claim Notice involving a Non-Third Party Claim,
        the Indemnified Party and the Indemnifying Parties shall meet and use
        their respective best efforts to agree on the validity and the amount of
        the Non-Third Party Claim covered by the Claim Notice. If, within thirty
        (30) days after the Indemnifying Party's receipt of such Claim Notice,
        the Parties cannot agree on the validity and the amount of the Non-Third
        Party Claim, the validity and the amount of the Non-Third Party Claim
        shall be determined by arbitration as provided below in Section 13.5.4.

13.5.4  All disputes between Sellers and Purchaser with respect to any matter
        relating to indemnification under this Agreement shall be determined by
        arbitration using the procedure for determining the arbitrator and other
        procedures for the arbitration contained in Section 3.9 of this
        Agreement, which provisions are incorporated herein mutadis mutandis.

13.6 Payment. Payments under this Article 13 and under any other indemnity
provision of this Agreement shall be made as follows:

13.6.1  If the Indemnifying Party is required to make any payment hereunder, the
        Indemnifying Party shall promptly pay the Indemnified Party the amount
        so determined. If there should be a dispute as to the amount or manner
        of determination of any indemnity obligation owed hereunder, the
        Indemnifying Party shall nevertheless pay when due such portion, if any,
        of the obligation as shall not be subject to dispute. The difference, if
        any, between the amount of the obligation ultimately determined as
        properly payable hereunder and the portion, if any, theretofore paid
        shall bear interest at the Agreed Rate. Upon the payment in full of any


                                     Page 48


        claim, the Indemnifying Party shall be subrogated to the rights of the
        Indemnified Party against any person or other entity with respect to the
        subject matter of this claim.

13.6.2  If all or part of any indemnification obligation under this Agreement is
        not paid when due upon resolution of the claim, then the Indemnifying
        Party shall pay upon demand to the Indemnified Party interest at the
        Agreed Rate on the unpaid amount of the obligation for each day from the
        date the amount became due until payment in full. As used herein,
        "Agreed Rate" means a rate per annum calculated on a 360-day basis which
        is equal to the lesser of (i) a rate which is two percent (2%) above the
        prime rate of interest of Chase Manhattan Bank, New York, New York, as
        announced or published by such bank from time to time (adjusted from
        time to time to reflect any changes in such rate determined hereunder),
        or (ii) the maximum rate from time to time permitted by Applicable Law.

13.7 Limitation on Damages. For the breach or non-performance by any Party of
any representation, warranty, covenant, or agreement contained in this
Agreement, the liability of the obligor shall be limited to direct actual
damages only, except to the extent that the obligee is entitled to specific
performance or injunctive relief. AS BETWEEN THE PARTIES, NOTWITHSTANDING
ANYTHING TO THE CONTRARY IN THIS AGREEMENT, NEITHER SELLERS NOR PURCHASER SHALL
BE LIABLE TO THE OTHER PARTY AS THE RESULT OF A BREACH OR A VIOLATION OF ANY
REPRESENTATION, WARRANTY, COVENANT, AGREEMENT, OR CONDITION CONTAINED IN THIS
AGREEMENT FOR SPECIAL, CONSEQUENTIAL, INCIDENTAL, PUNITIVE, EXEMPLARY, OR
INDIRECT DAMAGES, LOST PROFITS, OR OTHER BUSINESS INTERRUPTION DAMAGES, IN TORT,
IN CONTRACT, UNDER ANY INDEMNITY PROVISION, ARISING BY OPERATION OF LAW
(INCLUDING, WITHOUT LIMITATION, STRICT LIABILITY), OR OTHERWISE. WITH RESPECT TO
CLAIMS BY THIRD PERSONS, A PARTY MAY RECOVER FROM THE OTHER PARTY ALL COSTS,
EXPENSES, OR DAMAGES (INCLUDING, WITHOUT LIMITATION, SPECIAL, CONSEQUENTIAL,
INCIDENTAL, PUNITIVE, EXEMPLARY, OR INDIRECT DAMAGES), LOST PROFITS, AND OTHER
BUSINESS INTERRUPTION DAMAGES IN ADDITION TO ACTUAL DIRECT DAMAGES PAID OR OWED
TO ANY SUCH THIRD PERSON IN SETTLEMENT OR SATISFACTION OF CLAIMS AS TO WHICH THE
RELEVANT PARTY IS ENTITLED TO INDEMNIFICATION HEREUNDER.

13.8 Recording. As soon as practicable after the Closing, Purchaser shall file
and record all counterparts of the General Assignment in the appropriate
counties and, if necessary, with all relevant Governmental Bodies, and provide
Sellers, at its expense, with copies of all recorded counterparts of the General
Assignment.

13.9 Cooperation and Further Assurances. After the Closing, Sellers and
Purchaser agree to take such further actions and to execute, acknowledge, and
deliver all such further documents as are necessary or useful in carrying out
the purposes of this Agreement or of any document delivered pursuant to this
Agreement, including, but not limited to, the execution of state change of
operator forms and other required state regulatory filings. Each Party also
agrees to cooperate with each other by providing reasonable information which


                                     Page 49


may be required by the other Party for the purpose of administering the Assets
and preparing or reviewing the Post-Closing Adjustment Statement.

                                14. TERMINATION

14.1 Right of Termination. This Agreement may be terminated at any time at or
prior to the Closing only:

14.1.1  by mutual consent of the Parties;

14.1.2  by the Party not in material breach or material default of its
        obligations under this Agreement if, prior to the Closing Date, the
        other Party is in material breach or material default of its obligations
        under this Agreement;

14.1.3  by either Party pursuant to the provisions of Section 3.8, if
        applicable;

14.1.4  by Purchaser if the Closing does not occur because (i) any of the
        conditions contained in Article 11 hereof is not fulfilled by Sellers or
        waived by Purchaser on or before the Closing Date, and (ii) all of the
        conditions set forth in Article 10 hereof have been fulfilled on or
        before the Closing Date;

14.1.5  by Sellers if the Closing does not occur because (i) any of the
        conditions contained in Article 10 hereof is not fulfilled by Purchaser
        or waived by Sellers on or before the Closing Date, and (ii) all of the
        conditions set forth in Article 11 hereof have been fulfilled on or
        before the Closing Date;

14.1.6  by Purchaser pursuant to the terms of Section 1.1.3 or Section 8.10, if
        applicable; or

14.1.7  by Sellers pursuant to the terms of Section 2.3.1, if applicable.

14.2 Effect of Termination. If this Agreement is terminated pursuant to Section
14.1 above, this Agreement shall become void and of no further force or effect
(except for the provisions of Sections 9.1, 13.7, 16.10, and this Section 14.2,
which shall continue in full force and effect). If this Agreement is terminated
pursuant to Section 14.1.1, Section 14.1.3, Section 14.1.6, or Section 14.1.7,
neither Party shall have any further liability to the other Party as the result
of such termination. If Sellers terminate this Agreement pursuant to Section
14.1.2 or Section 14.1.5 as the result of Purchaser's failure to fulfill any
condition set forth in Article 10, then in addition to such right of
termination, the sole and exclusive remedy of Sellers with respect to such
breach or default by Purchaser or failure by Purchaser to fulfill such
conditions shall be the right to retain the Performance Deposit in accordance
with Section 2.3 hereof. If Purchaser terminates this Agreement pursuant to
Section 14.1.2 or Section 14.1.4 as the result of Sellers' failure to fulfill
any condition set forth in Article 11, then in addition to such right of
termination and the right to the return of the Performance Deposit under Section
2.3 hereof, Purchaser shall be entitled to pursue any and all remedies available
to Purchaser at law or in equity (but not including specific performance);
provided, however, that any damages recovered by Purchaser from Sellers with
respect to such breach or default by Sellers or such failure by Sellers to
fulfill such conditions shall be limited to direct, actual damages in an amount
not to exceed the amount of the Performance Deposit. Notwithstanding anything to


                                     Page 50


the contrary contained in this Agreement, upon any termination of this Agreement
pursuant to Section 14.1, Sellers shall be free immediately to enjoy all rights
of ownership of the Assets and to sell, transfer, encumber, or otherwise dispose
of the Assets to any party without any restriction under this Agreement; and
Purchaser shall be liable for all actual, incidental, and consequential damages
(including, without limitation, lost profits) if it attempts to interfere in any
way with any such enjoyment or action by Sellers; provided that the institution
of a lawsuit for actual, incidental, or consequential damages (including,
without limitation, lost profits) by Purchaser (including, without limitation, a
lawsuit based on a claim that Sellers breached Section 8.11) shall not be deemed
to be an attempt to interfere with such enjoyment or action by Sellers, as long
as Purchaser, upon written request by Sellers, provides reasonable assurances to
any party (as designated by Sellers) contemplating the purchase from Sellers of
the Assets or any portion thereof that Purchaser claims no interest in the
Assets by virtue of a right to enforce specific performance under this Agreement
and shall waive any rights it may have to enjoin the sale of the Assets to such
party and to institute any actions at law against such party with respect to
tortious interference with its rights under this Agreement, unless Purchaser has
reasonable cause to believe that the party in question has tortiously interfered
with its rights under this Agreement.

                                   15. TAXES

15.1 Apportionment of Ad Valorem and Property Taxes. All ad valorem taxes, real
property taxes, Personal Property taxes, and similar tax obligations (the
"Property Taxes") with respect to the Assets for the tax period in which the
Effective Date occurs shall be apportioned, based on the Effective Date, between
Sellers, on the one hand, and Purchaser, on the other hand, and, if already paid
by Sellers, an appropriate increase in the Purchase Price shall be made pursuant
to Section 2.4.5. If such Property Taxes are not already paid, but the tax
liability is known or can be reasonably estimated, Sellers' portion of such
Property Taxes shall be credited to Purchaser's account pursuant to Section
2.4.11. Purchaser shall pay or cause to be paid to the taxing authorities all
Property Taxes of which it has knowledge not already paid relating to the tax
period in which the Effective Date occurs and if appropriate adjustments to the
Purchase Price pursuant to Section 2.4 were not made at the Closing or in
connection with the Post-Closing Adjustment Statement, Purchaser shall invoice
Sellers (with copies of applicable tax bills and assessments to confirm same)
for Sellers' apportioned shares of such Property Taxes, and Sellers shall pay
the same within thirty (30) days of receipt of said notice. Purchaser shall
defend, indemnify, and hold Sellers harmless with respect to the payment of such
Property Taxes of which Purchaser has knowledge and which Purchaser is obligated
to pay to the applicable taxing authorities (including any interest or penalties
assessed thereon), provided Sellers pay their respective shares (as apportioned
hereunder) within thirty (30) days of being properly invoiced (with accompanying
documents to support the invoice) by Purchaser. For the tax period in which the
Effective Date occurs, Sellers agree (i) to forward immediately to Purchaser
copies of all Property Tax reports and returns received by Sellers after the
Closing and (ii) to provide Purchaser with appropriate information which is
necessary for Purchaser to file any required Property Tax reports and returns.
All tax apportionments determined under this Section 15.1 and Section 15.2 shall
be deemed a final settlement of Property Taxes between the Parties.
Notwithstanding the foregoing, Sellers or Purchaser may contest with the
appropriate taxing authority the amount of or liability for any Property Tax
apportioned to it pursuant to this Section 15.1. The Party pursuing the contest
shall indemnify the other Party from and against all Costs incurred by the other
Party in connection with the contest, and upon final settlement or resolution of


                                     Page 51


the contest, the economic burden of the contested tax shall be adjusted among
the Parties in a manner consistent with the intent of this Section 15.1.

15.2 Taxes Paid for Others. To the extent Purchaser has a right to do so,
Purchaser agrees to withhold from future income distributions to royalty owners,
overriding royalty interest owners, and other production burden holders as to
the Assets amounts sufficient to reimburse Sellers for various taxes (e.g.,
Property Taxes, severance, environmental excise, etc.) paid by Sellers on behalf
of such interest holders while Sellers owned the Assets (which shall include
withholdings for co-working interest owners when Sellers have paid such owners'
taxes and have not previously collected such taxes through joint interest
billings). Sellers will provide Purchaser with sufficient documentation to allow
Purchaser to confirm amounts to be withheld, and each Seller, severally
according to its ownership interest in the Assets and not jointly, will
indemnify and hold Purchaser harmless from liability for deducting such sums as
directed by Sellers. Purchaser agrees promptly to forward to Sellers such sums
which are withheld pursuant to this Section 15.2.

15.3 Sales Taxes. Purchaser shall pay, or cause to be paid, all sales, use,
transfer, and similar taxes, if any, resulting from the sale and transfer of the
Assets to Purchaser hereunder (including without limitation, all applicable
conveyance, transfer and recording fees, and real estate transfer stamps or
taxes imposed on the transfer of the Assets pursuant to this Agreement), and
shall prepare and file all tax returns required to be filed with respect to such
taxes.

15.4 Other Taxes. All production, severance, excise, and other similar taxes
that are based upon production of, or income or revenues from, Hydrocarbons
attributable to the Assets prior to the Effective Date shall be paid by Sellers,
and all such taxes relating to such production on or after the Effective Date
shall be paid by Purchaser. The Party responsible for payment of such taxes
shall prepare and file all tax returns required to be filed in respect thereof.
This Section 15.4 shall not apply to any tax to the extent specifically
otherwise provided elsewhere in this Agreement.

15.5 Cooperation. Each Party shall cooperate with the other Party and provide
the other Party with all information in its possession or to which it has access
which may be reasonably required by the other Party in connection with the
preparation of any tax return relating to the Assets, the audit or examination
of any such returns by any tax authority, and the determination of or contest of
any tax relating to the Assets. Notwithstanding anything to the contrary in this
Agreement, neither Party shall be required at any time to disclose to the other
Party any tax returns or other confidential tax information except to the extent
required by Applicable Law or court order.

15.6 Tax Indemnity. Each Seller, severally according to its ownership interest
in the Assets and not jointly, shall indemnify and hold harmless Purchaser, and
Purchaser shall indemnify and hold harmless Sellers, in each case with respect
to the payment of any taxes, including any interest or penalties assessed
thereon, for which the indemnifying Party is responsible pursuant to the
provisions of this Article 15.

such consent shall be required in the event of an assignment and delegation by a
Party of its rights and duties under this Agreement to an Affiliate of such
Party, or the pledging or assignment of, or the granting of a security interest

16.10   Confidentiality.

16.10.1 Sellers' and Purchaser's respective obligations under the
        Confidentiality Agreement shall terminate upon the Closing. Purchaser
        agrees that if this Agreement is terminated prior to the Closing for any

        terms thereof.

                                     Page 54


        Purchaser unless (i) Sellers shall have consented thereto in writing,
        (ii) disclosure is required pursuant to a court order or by subpoena or
        similar legal process, or (iii) disclosure is made on advice of its
        counsel, pursuant to a request by a Governmental Body, pursuant to
        Applicable Laws, or to comply with the rules and regulations of any
        stock exchange, or (iv) such information has been previously made public
        (except as a result of a breach of this Agreement); provided, however,
        Purchaser may disclose such information to its representatives, agents,
        attorneys, consultants, and auditors as needed, but in such event,
        Purchaser shall use reasonable efforts to cause such persons to keep
        such information confidential.

16.11 Exhibits and Schedules. All references in this Agreement to Exhibits shall
be deemed to be references to such Exhibits as the same may be amended and
supplemented by mutual agreement of the Parties through and as of the Closing,
and all such Exhibits, as amended and supplemented, are hereby incorporated into
this Agreement by reference.

16.12 Publicity. Prior to making any press or other similar release or public
announcements regarding the transactions contemplated by this Agreement, each
Party shall consult with the other Party regarding the proposed contents
thereof, but no approval thereof shall be required.

16.13 Use of Sellers' Names. Purchaser agrees to use reasonable efforts, as soon
as practicable after the Closing, but in any case no later than one hundred
eighty (180) days after the Closing, to remove or cause to be removed from the
Assets, to the extent it has knowledge of the existence of same, all evidence of
the names and marks used by Sellers and all variations and derivatives thereof
and logos relating thereto, and will not thereafter make any commercial use of
such names, marks and logos.

16.14 Severability. If any term or other provision of this Agreement is invalid,
illegal, or incapable of being enforced by any rule of law or public policy, all
other conditions and provisions of this Agreement shall nevertheless remain in
full force and effect so long as the economic or legal substance of the
contemplated transactions is not affected in any material adverse manner to
either Party. Upon such determination that any term or other provision is
invalid, illegal, or incapable of being enforced, the Parties shall negotiate in
good faith to modify this Agreement so as to effect the original intent of the
Parties as closely as possible in an acceptable manner to the end that the
contemplated transactions are fulfilled to the extent possible.

16.15 Affiliate. For purposes of this Agreement, the term "Affiliate" (whether
capitalized or not) shall mean, when used with respect to a person or entity,
any other person or entity (i) which directly or indirectly (through one or more
intermediaries) controls, or is controlled by, or is under common control with,
such first mentioned person or entity, or (ii) which beneficially owns, holds,
or controls fifty percent (50%) or more of the interest of such first mentioned
person or entity. The term "control" (including the terms "controlled by" and
"under common control with") means the possession, directly or indirectly or as
trustee or executor, of the power to direct or cause the direction of the
management policies of a person or entity, whether through the ownership of
stock, as trustee or executor, by contract or credit arrangement or otherwise.

16.16 Attorney's Fees. Any Party successfully pursuing a claim for the
enforcement of any provision of this Agreement, including, without limitation,


                                     Page 55


agreements of indemnity contained herein or any of the documents to be delivered
pursuant hereto, shall be entitled to recover from the unsuccessful Party
reasonable attorneys' fees, court costs, and other expenses incurred by the
successful Party in such action.

16.17 Interest. In the event that either Party brings suit to collect any amount
owed by the other Party hereunder, such other Party shall pay the Party bringing
such suit interest on any amount so collected from the date of demand (or, if
earlier, the date due) until the date of payment at the Agreed Rate.

16.18 Exchange. Sellers shall have the right to utilize all or part of the
Assets as part of a tax deferred exchange pursuant to Section 1031 of the IRC
and applicable state and local tax laws. In connection with an exchange, and
notwithstanding the terms of Section 16.4, all or part of the rights of Sellers
under this Agreement may be assigned, without the need for Purchaser's consent,
to an intermediary, escrow agent, trustee, or other exchange accommodation
party, provided that such assignment shall not relieve Sellers of their
obligations to Purchaser hereunder. Purchaser shall cooperate with Sellers in
effecting such an exchange, including, without limitation, the execution of
escrow instructions and other instruments, provided that: (i) the acquisition
and exchange of any exchange property shall not impose upon Purchaser any
additional financial obligation other than as set out in this Agreement; (ii)
Purchaser shall have no obligation to become a holder of record title to any
exchange property; (iii) each Seller, severally according to its ownership
interest in the Assets and not jointly, shall indemnify and hold Purchaser
harmless from any and all Costs which Purchaser incurs or to which Purchaser may
be exposed as a result of Purchaser's participation in the contemplated
exchange, including reasonable attorneys' fees and costs of defense; (iv) the
Closing shall not be delayed or affected by reason of such exchange nor shall
the consummation or accomplishment of such exchange be a condition precedent or
condition subsequent to Sellers' obligations under this Agreement; (v) Purchaser
shall not, by this Agreement or acquiescence to such exchange, have its rights
under this Agreement affected or diminished in any manner; and (vi) Purchaser
shall not, by this Agreement or acquiescence to such exchange, be responsible
for compliance with or deemed to have warranted to Sellers that such exchange in
fact complies with Section 1031 of the IRC or any state or local tax law. If any
exchange contemplated by Sellers should fail to occur, for whatever reason, the
sale of the Assets shall nonetheless be consummated as provided herein.

16.19 Data. With respect to all of its operations on the Properties from and
after the Closing Date, Purchaser agrees to furnish the following information to
Doug Sartoris within five (5) days of Purchaser's receipt of such information:
a) copies of the daily operations reports during drilling, re-working, logging,
testing, completing, re-completing, sidetracking or similar operations on the
Properties; and b) mud logs, logs, well tests, formation tests, directional and
velocity surveys, cores, pressure tests and related information.

of which shall be considered an original for all purposes. Facsimile signatures
shall be deemed original signatures for purposed of enforcing this Agreement.
