              BERRY PETROLEUM CLOSES ACQUISITION
              OF YUMA COUNTY NIOBRARA GAS ASSETS

Bakersfield, CA - January 28, 2005 - Berry Petroleum Company
(NYSE:BRY)  has closed the previously announced  acquisition
of Yuma County, Colorado, Niobrara natural gas assets from J-
W  Operating  Company. The acquisition  consists  of  a  52%
working  interest  ownership (43% net revenue  interest)  in
approximately 130,000 gross acres and over 650 producing gas
wells  concentrated in 20 productive fields in  northeastern
Colorado,   as  well  as  100%  ownership  in  certain   gas
compression   and   transportation   assets.   Current   net
production  is  approximately  8.8  million  cubic  feet  of
natural  gas  per day and the Company estimates  net  proved
reserves  to  be  approximately 87 billion cubic  feet.  The
adjusted purchase price of $105 million will be financed  by
bank   borrowings   under  the  Company's  existing   credit
facility.

Robert  F.  Heinemann, president and CEO of Berry  Petroleum
Company, stated, "The Yuma County properties provide Berry a
solid   producing   asset   with   significant   development
opportunities.  Our  on-going strategy  is  to  lighten  our
production mix and strengthen our development portfolio.  We
like this asset because of its low geologic risk, repeatable
development opportunities and low operating costs.  We  have
identified   over   150   drilling  locations   on   80-acre
development spacing and an additional 500 locations  on  40-
acre spacing."

Michael   Duginski,  senior  vice  president  of   corporate
development, added, "Combining this acreage and the  acreage
from  the  pending Tri-state acquisition from  Bill  Barrett
Corporation provides Berry with interests in almost  500,000
acres  in the Niobrara play.  This provides us with a  solid
base  of  production  as well as the opportunity  to  create
further  significant value upon exploration and  development
success. Recent increases in pipeline capacity have provided
an  outlet for more production from this region which should
improve  our  gas  sales  price.  Prices  for  this   region
currently are about $.85 per thousand cubic feet (Mcf) lower
than the Henry Hub index."

Logan Magruder, senior vice president of operations for  the
Rocky  Mountain  region,  added, "We  are  excited  to  take
control  of  this quality producing asset and are proceeding
to  quickly  integrate the assets into Berry. We have  added
the  right people to our engineering and operational  staff,
many  of whom are already familiar with this asset. We  plan
to drill 60 wells and complete 25 workovers this year in the
Niobrara   formation   with  an   expected   investment   of
approximately  $5 million.  We will start  drilling  in  the
first quarter of 2005 and aggressively pursue cost reduction
opportunities  to  seek to lower the  operating  cost  below
$1.50 per Mcf."

(vi) The aggregate allocated values of any of such Seller's Assets affected by a Casualty Loss in the event Purchaser so elects in accordance with Section 3.12(b);

(vii) An amount equal to such Seller's allocable share, if any, of the Environmental Remediation Adjustment set forth in Section 3.8(b);

(viii) An amount equal to the amount of such Seller's allocable share, if any, of all suspended funds plus accrued interest in the Suspense Accounts; and

(ix) Any other amount agreed upon by Sellers and Purchaser in writing prior to Closing.

2.5 Determination of Adjusted Purchase Price.

(a) Not less than five (5) days prior to Closing, Sellers shall prepare and submit to Purchaser for review and approval a draft settlement statement (in substantially the format set forth in Schedule 2.5 hereto) reflecting Sellers' good faith estimate of the Adjusted Purchase Price ("Closing Settlement Statement"), accompanied by all documentation reasonably required to confirm the information on the Closing Settlement Statement. The Closing Settlement Statement shall allocate the estimated Purchase Price adjustments and the Adjusted Purchase Price among J-W, Cohort, JWG, JWP, WLTD, CAW and LPM, and shall set forth the aggregate estimated Purchase Price Adjustments and the Adjusted Purchase Price calculated as to all Sellers taken together. Sellers represent that the Closing Settlement Statement will have been based on actual information available to Sellers at the time of its preparation and upon Sellers' good faith estimates and assumptions. The Parties shall negotiate in good faith and attempt to agree on the Closing Settlement Statement prior to Closing. Sellers shall provide additional information relating to the Closing Settlement Statement that is reasonably requested by Purchaser. In the event any estimated Purchase Price adjustments are not agreed upon prior to Closing, the estimate of the Adjusted Purchase Price for purposes of Closing shall be calculated based on Sellers' and Purchaser's agreed upon estimated Purchase Price adjustments and Sellers' good faith estimate of any disputed amounts (and any such disputes shall be resolved by the Parties or the Accounting Referee (as provided in clause (b) below) in connection with resolution of the Final Settlement Statement).

(b) As soon as reasonably practicable after the Closing but not later than ninety (90) days following the Closing Date, Sellers shall prepare and deliver to Purchaser a final settlement statement ("Final Settlement Statement") setting forth exceptions to the Closing Settlement Statement and each proposed final adjustment to the Purchase Price and showing the calculation of each such adjustment. The Final Settlement Statement shall take into account only Adjustment Period Costs, receipts and other expense and revenue items relating to the Adjustment Period, or erroneous calculations set forth in the Closing Settlement Statement, in each case of which Seller or Purchaser becomes aware prior to the 150th day following Closing. Purchaser and its accountants shall be provided access to all of Seller's books, records, computer runs and other documents containing information on which the Final Settlement Statement is based for purposes of verifying the information contained in the Final Settlement Statement. As soon as reasonably practicable but not later than thirty (30) days following receipt of such Final Settlement Statement and records, Purchaser shall deliver to Sellers a written report containing any changes that Purchaser proposes be made to such Statement. If the Purchaser fails to deliver such report prior to the expiration of such thirty (30) day period, then the Final Settlement Statement shall become final and binding upon the Parties. If Purchaser timely submits a report taking exception to the Final Settlement Statement, then the Parties shall undertake to agree on the Final Settlement Statement and the final Adjusted Purchase Price no later than one hundred fifty (150) days after the Closing Date. In the event that the Parties cannot reach agreement on the Final Settlement Statement and Adjusted Purchase Price within such period of time, the Parties shall either (i) agree to extend the 150-day period for a fixed period of time and cooperate to resolve any remaining Settlement Statement differences; or (ii) designate a mutually acceptable accounting firm (the "Accounting Referee") to determine such matters that remain unresolved with respect to adjustments to the Purchase Price. Sellers and Purchaser shall use their respective commercially reasonable efforts to cause the Accounting Referee to render a decision resolving the matters submitted to it within thirty (30) days following submission thereto. The costs of the Accounting Referee shall be borne 50% by Sellers and 50% by Purchaser. The decision of the Accounting Referee as to the Final Settlement Statement and Adjusted Purchase Price shall be final and binding upon the Parties and a final resolution of any disputes relating thereto to the same extent as a final judgment of a court of competent jurisdiction.

(c) On the first business day following the day the Final Settlement Statement becomes final and binding or, if applicable, the day on which the Accounting Referee renders its decision, Sellers or Purchaser, as the case may be, shall pay the other Party the amount, if any, shown on the Final Settlement Statement (including any modification resulting from the provisions of this Section 2.5) as being due to the other Party. All payments due hereunder shall be made by electronic funds transfer of immediately available funds to an account or accounts designated by the receiving Party.

Article III

Title, Environmental and Casualty Loss Matters

3.1 Seller's Title. Sellers will on the Closing Date have Defensible Title to the Assets and the right to convey such Assets free and clear of any and all liens, mortgages, pledges, claims, preferential purchase rights, requirements for consent to assign or other material defects or encumbrances, except for the Permitted Encumbrances (as defined in Section 3.3 below). At Closing, all of Sellers' right, title and interest to the Assets shall be transferred and conveyed by means of one or more assignments, bills of sale or deeds without representation or warranty of title, express or implied, except as to claims arising by, through, or under the Seller who purports to own the Assets which are subject to such transfer instrument, but not otherwise, and otherwise in the forms attached as exhibits hereto.

3.2 Definitions of "Defensible Title" and "Title Defects".

(a) As used in this Agreement, the term "Defensible Title" shall mean that title of the applicable Seller which:

(i) is recorded or filed and deducible of record (to the extent constituting real property), including the Bureau of Land Management and state records for federal and state leases (as applicable) and is free from doubt such that a prudent person engaged in the business of the ownership, development and operation of producing oil and gas properties, and gathering and compression facilities, in the area of the Assets, with knowledge of all the facts and their legal effect, would be willing to accept the same;

(ii) with respect to a PUD location or Well, entitles the applicable Seller to own, receive and retain, without reduction, suspension or termination, not less than the net revenue interest identified on Exhibit J or Exhibit K, respectively, of all Production produced, saved and marketed from each such PUD location or Well;

(iii) with respect to a PUD location or Well, requires the applicable Seller to bear no greater share of costs and expenses relating to the exploration, development, maintenance, operation, plugging and restoration of such Lease or Well than the working interest identified on Exhibit J or Exhibit K, respectively, for each such PUD location or Well (unless such Seller's net revenue interest therein is proportionately increased); and

(iv) is free and clear (except for Permitted Encumbrances as defined in Section 3.3 below) of all liens, mortgages, pledges, claims, preferential purchase rights, requirements for consent to assign, or other material defects or encumbrances of any kind and character.

(b) As used in this Agreement, the term 'Title Defect" shall mean any defect, other than a Permitted Encumbrance, which alone, or in conjunction with other defects, causes a Seller not to have Defensible Title to an Asset.

3.3 Definition of Permitted Encumbrances. As used in this Agreement, the term "Permitted Encumbrances" shall mean:

(a) lessor's royalties, overriding royalties, reversionary interests, net profits interests and similar burdens deducible of record to the extent accounted for in the determination of and which do not reduce the net revenue interest for any PUD location or Well below that set forth on Exhibit J or Exhibit K, respectively;

(b) division orders to the extent not in conflict with the net revenue interests or working interests set forth on Exhibit J or Exhibit K, respectively;

(c) preferential rights to purchase and required third-party consents to assignment with respect to which waivers or consents are obtained from the appropriate parties, or the appropriate time period for asserting the rights has expired without the exercise of the rights prior to the Closing Date;

(d) any non-perfected liens for taxes or assessments not yet due and payable, or those that are being contested by Sellers in the ordinary course of business;

(e) any non-perfected materialman's mechanic's, repairman's, employee's contractor's, operator's and other similar liens or charges arising in the ordinary course of business, to the extent that the obligations covered thereby are not yet due and payable, or those that are being contested by Sellers in the ordinary course of business;

(f) all rights to consent by, required notices to, filings with, or other actions by governmental entities in connection with the sale or conveyance of oil and gas leases or interests therein if they are customarily obtained subsequent to the sale or conveyance;

(g) easements, rights-of-way, servitudes, permits, surface leases and other rights in respect of surface operations that individually or in the aggregate do not materially interfere with the value, ownership, development or operation of the Assets;

(h) all rights reserved to or vested in any governmental, statutory or public authority ("Governmental Authority") to control or regulate any of the Leases or Wells in any manner, and all applicable laws, rules and orders of Governmental Authorities in effect as of the Effective Date;

(i) any encumbrance or charge on or affecting the Assets which is removed or discharged by Seller at or prior to Closing;

(j) defects or irregularities of title (i) arising out of a lack of a survey, (ii) that are cured or curable by possession under applicable statutes of limitation and statutes relating to prescription, (iii) arising out of events or transactions which have been barred by limitations, (iv) arising out of failure to recite marital status or the omission of succession or heirship proceedings, or (v) arising out of prior oil and gas leases which, on their face, have expired and which have not been released of record; and

(k) any Title Defects that Purchaser shall have expressly waived in writing.

3.4 Title Failure: Defect Adjustments.

(a) "Defective Interest" shall mean each Seller's interest in any Asset or any portion thereof that is affected by a Title Defect. Purchaser shall give to J-W written notice ("Title Defect Notice") of any Title Defect of which it is aware promptly after it becomes aware of such Defect but in any event on or before a date that is seven (7) days prior to the Closing Date ("Title Defect Notice Date"). Such Title Defect Notice shall be in writing and shall include (i) a description of the Defective Interest, (ii) the basis for the Title Defect that Purchaser believes causes such interest in that Asset to be treated as a Defective Interest, plus copies of documents supporting such claim, (iii) the amount by which Purchaser reasonably believes the value of the Defective Interest has been reduced by the Title Defect (the "Title Defect Value"), and (iv) the computations and information upon which Purchaser's belief is based. Except as otherwise provided in Section 3.8(a), any Title Defect not asserted in writing by Purchaser prior to the Title Defect Notice Date shall be deemed waived by Purchaser for all purposes. No Title Defect may be asserted by Purchaser unless the associated Title Defect Value exceeds [***] ("Qualified Title Defect Value").

(b) No later than three (3) days following receipt of a Title Defect Notice, Sellers shall give written counter-notice to Purchaser (i) whether Sellers agree or disagree that the asserted Title Defect exists, (ii) that Sellers either (A) will attempt to cure an agreed Title Defect, or (B) do not intend to attempt to cure an agreed Title Defect, and (iii) whether Sellers agree or disagree with the Qualified Title Defect Value asserted by the Purchaser. Sellers' failure to deliver a counter-notice to Purchaser within such three (3)-day period shall be deemed a waiver by Sellers of their rights to attempt to cure a Title Defect, or to contest Purchaser's identification of a Title Defect and Defective Interest or calculation of the Qualified Title Defect Value. In such event, the Purchase Price will be reduced by the aggregate amount of all such Qualified Title Defect Values asserted by Purchaser (any such adjustment, the "Title Defect Adjustment"); provided that, for purposes of calculating the Title Defect Adjustment, the entire Title Defect Value of each Qualified Title Defect Value shall be included.

(c) If Sellers timely notify Purchaser of their intent to attempt to cure any asserted Title Defect, Sellers shall have a period of thirty (30) days from the receipt of the Title Defect Notice (the "Cure Period") to attempt to cure such asserted Title Defect at Sellers' own expense, and if applicable, the Closing Date shall be extended until the third business day after the earliest to occur of the following: (A) all such Title Defects are cured to the reasonable satisfaction of Purchaser, (B) Purchaser's receipt of Sellers' notice that Sellers are unable to cure the Title Defect, and (C) the expiration of the Cure Period, but in any event no later than the Outside Closing Date (as defined in Section 8.1(a)). If, by the end of the Cure Period, Sellers fail to cure to the reasonable satisfaction of Purchaser any asserted Title Defect that Seller attempts to cure, the Purchase Price shall be reduced by the Title Defect Adjustment calculated with reference to the Title Defects which Sellers have not so cured, and Sellers shall be relieved of any additional obligations to Purchaser with respect to such Title Defects.

(d) If Sellers notify Purchaser either that Sellers disagree with the existence of a Title Defect or Purchaser's calculation of the Qualified Title Defect Value, or if Purchaser notifies Sellers that it disputes Sellers' purported cure of a Title Defect, and if the Parties are unable to resolve their disagreement through good faith negotiation over a period of ten business days commencing on the date of receipt of the applicable notice, then the existence of the Title Defect, the calculation of the Qualified Title Defect Value, and/or the validity of Sellers' purported cure of a Title Defect will be determined by arbitration pursuant to Section 3.6 hereof.

(e) In determining which Assets or portions thereof are Defective Interests and the applicable Title Defect Value, it is the intent of the Parties to include, when possible, only that portion of the Assets materially and adversely affected by the Title Defect. The Title Defect Value shall not exceed the allocated value of the affected Asset as set forth on Exhibit J hereto, multiplied by the total affected working interest in that affected Asset. Subject to such limitation, any Title Defect Value shall be determined by the Parties in good faith taking into account all relevant factors, including the following: (i) the allocated value of the Asset affected by the Title Defect, (ii) the reduction in net revenue interest or the increase in working interest (without a corresponding increase in net revenue interest) of the Defective Interest, (iii) the productive status of the Defective Interest and the present value of future income expected to be produced therefrom, (iv) the amount of undrilled leasehold related to such Defective Interest, (v) the legal effect of the Title Defect, and (vi) the cost of curing the Title Defect.

3.5 Increases in Net Revenue Interest. In the event Sellers' net revenue interest in any Well or PUD location, as the same may be delivered or deliverable to Purchaser at Closing, exceeds the net revenue interest set forth for such Well or PUD location on Exhibit K or Exhibit J, respectively, then, as to each such Well or PUD location, Sellers shall be entitled to an upward adjustment of the Purchase Price calculated by subtracting (a) $10,000 from (b) the product obtained by multiplying (i) the allocated value of such Well or PUD location as set forth on Exhibit J times (ii) the quotient of (A) Sellers' actual net revenue interest in such Well or PUD location as delivered or deliverable to Purchaser at Closing divided by (B) the net revenue interest set forth for such Well on Exhibit K, or for such PUD location on Exhibit J. Any positive difference resulting from application of such formula is referred to herein as a "Net Revenue Adjustment."

3.6 Arbitration Procedures. If any matter is required by this Article to be arbitrated, such arbitration shall be conducted as set forth in this Section 3.6.

(a) The Parties shall jointly select an acceptable person, who shall be an oil and gas title attorney with at least ten years of experience in Colorado title matters, as the sole arbitrator under this Agreement. If the Parties are unable to agree upon the designation of a person as arbitrator, then either Sellers or Purchaser, or both such Parties, may in writing request the American Arbitration Association to appoint a qualified arbitrator.

(b) Any arbitration hearing shall be held at a place in Denver, Colorado acceptable to the arbitrator.

(c) The arbitrator shall settle disputes regarding the existence of Title Defects, Defective Interests, Qualified Title Defect Values and/or Seller's attempts to cure any Title Defects, in each case in accordance with applicable Colorado law and the procedural provisions of the Texas General Arbitration Act and the Rules of the American Arbitration Association, to the extent such rules do not conflict with Colorado law, the terms of such Act or the terms hereof. The decision of the arbitrator shall be binding upon the Parties, and may be enforced in any court of competent jurisdiction. Sellers and Purchaser, respectively, shall bear their own legal fees and other costs incurred in presenting their respective cases. The charges and expenses of the arbitrator shall be shared equally by Sellers and Purchaser.

(d) The arbitration shall commence within ten (10) days after the arbitrator is selected as set forth in Section 3.6(a) above. In fulfilling his duties hereunder, the arbitrator shall be bound by the terms of this Agreement. In fulfilling any of his arbitration duties, the arbitrator may consider such other matters as in the opinion of the arbitrator are necessary or helpful to make a proper evaluation. Additionally, the arbitrator may consult with and engage disinterested third parties, including, without limitation, petroleum engineers, and other attorneys and consultants, to advise the arbitrator, the charges of whom shall be borne equally by the Parties.

(e) If any arbitrator selected hereunder should die, resign or be unable to perform his duties hereunder the parties or if the parties are unable to agree, the American Arbitration Association shall select a replacement arbitrator. The aforesaid procedure shall be followed from time to time as necessary.

3.7 Effect of Defective Interests on Closing. If Purchaser asserts any Title Defects, Defective Interests and/or any Title Defect Adjustment, the following shall apply:

(a) Subject to satisfaction or waiver of the closing conditions, if Purchaser claims the value of a Title Defect is a Qualified Defect Value, the Parties shall proceed to the Closing as provided in this Agreement if (i) Sellers cure the asserted Title Defects which have Qualified Defect Value to the reasonable satisfaction of Purchaser, (ii) Purchaser agrees to waive the relevant Title Defects and purchase the Defective Interests notwithstanding the asserted Title Defects, or (iii) Purchaser and Sellers agree to the amount of the Title Defect Adjustment and the Purchase Price is reduced by such amount.

(b) If any matter is referred to arbitration under Section 3.6 of this Agreement, then, except as provided in clause (c) below, the Parties shall proceed to Closing, the asserted Defective Interests, each of which have an alleged Qualified Defect Value, shall be conveyed to Purchaser, and the amount payable by Purchaser at Closing shall be reduced by an amount equal to the aggregate Qualified Title Defect Values asserted by Purchaser (the "Withheld Payment"). The Withheld Payment shall be placed in the Performance Deposit Account. The Withheld Payment and any interest thereon shall be paid as follows:

(i) To Sellers, if and to the extent the arbitrator determines that (A) Title Defects asserted by Purchaser are not Title Defects; (B) Title Defects asserted by Purchaser have been cured; (C) Qualified Title Defect Values asserted by Purchaser exceed the actual Qualified Title Defect Values; or (D) an asserted Title Defect Value is not a Qualified Title Defect Value; and

(ii) To Purchaser, if and to the extent the arbitrator determines that Title Defects have been correctly asserted by Purchaser and that Title Defect Values have been correctly calculated by Purchaser and are Qualified Title Defect Values.

(c) If any matter is referred to arbitration under Section 3.6 of this Agreement and the aggregate Qualified Title Defect Values asserted by Purchaser with respect to the matters under arbitration exceeds [***] of the Purchase Price, then, unless this Agreement is terminated by Sellers or Purchaser pursuant to Article 7.2(g) or 7.1(f) hereof, Closing shall be postponed (but no later than the Outside Closing Date) until the arbitrator renders his final decision. Promptly after the arbitrator renders his decision, the Parties shall proceed to Closing. Thereafter the Assets, including any Defective Interests, shall be conveyed to the Purchaser, and the Purchase Price shall be reduced by the aggregate Title Defect Adjustment, if any.

3.8 Preferential Rights and Environmental Inspections.

(a) On or prior to Closing, Sellers shall furnish to Purchaser copies of all written waivers of preferential purchase rights and consents to the sale and transfer of the Assets which have been obtained from any third party. If any third party waiver of preferential purchase right or required consent (other than consents to be obtained from the State of Colorado or the Bureau of Land Management or other similar governmental entity that are customarily obtained subsequent to the sale or conveyance) applicable to the sale and transfer of the Assets, whether or not such waiver or required consent is identified on Schedule 3.8(a), is not obtained prior to the Closing, Purchaser may elect to treat that portion of an Asset subject to such waiver or consent requirement as a Defective Interest by giving Sellers written notice thereof on or prior to Closing. Should a third Person fail to exercise its preferential right to purchase as to any portion of the Assets, or fail to grant the necessary consent, prior to Closing, and the time to exercise such preferential right has not expired as of the Closing, either Party shall have the right to delay the Closing Date until the last to occur of (i)(A) the date an election is received from such third Person, or (B) the time to exercise the preferential right has expired, (ii) the necessary consents have been obtained, as applicable, or (iii) the Outside Closing Date.

(b) Purchaser shall have until the third business day preceding Closing to conduct, at its sole risk and expense, an ASTM Phase I environmental site assessment of the Assets using a reputable environmental consulting or similar firm (together with the Phase II environmental site assessment below, "Purchaser's Environmental Inspection"). Subject to the consent and cooperation of third parties, Sellers shall cooperate with reasonable requests by Purchaser and its agents to conduct Purchaser's Environmental Inspection. Purchaser will give Sellers 72-hour advance notice by fax or email of the locations and times of inspection to allow Sellers to be present to witness such inspections. Should Purchaser in good faith require a Phase II environmental site assessment including sampling, testing or drilling for core samples and/or water samples from the Assets, such sampling, testing or drilling shall only be done with the specific written permission of Sellers, which shall not unreasonably be withheld. Sellers shall have the right to receive a split sample from each so taken. Upon advance notice to Sellers, Purchaser shall have the right to delay the Closing Date for such periods of time as is necessary in good faith to permit Purchaser to complete Purchaser's Environmental Inspection, but in no event later than the Outside Closing Date. Purchaser shall give to Sellers written notice ("Environmental Defect Notice") of any environmental condition of which it is aware promptly after it becomes aware of such condition but in any event no less than third business day preceding Closing. The estimate of the cost of remediating any and all environmental conditions identified in Purchaser's Environmental Inspection and existing or occurring prior to the Closing Date shall be set forth in the Environmental Defect Notice; provided that no such cost estimate shall be included in the Environmental Defect Notice unless the cost estimate exceeds $5,000 per Well, compressor site or other location. Each such good faith remediation cost estimate exceeding $5,000.00 per Well, compressor site or other location is referred to herein as an "Environmental Remediation Adjustment". Purchaser shall be deemed to have waived any right to an Environmental Remediation Adjustment with respect to any environmental condition that is not described in a Environmental Defect Notice delivered to Sellers on or prior to the third business day preceding Closing.

(c) In accordance with Section 2.4(b)(vii) above, the Purchase Price shall be reduced by the aggregate amount of the Environmental Remediation Adjustments unless, no later than the business day preceding the Closing Date, Sellers notify Purchaser in writing of their intention to either (i) retain the Asset(s) affected by the environmental condition (provided that such retention right shall be limited to Wells (and Leases insofar as they contribute to the drilling and spacing units for such Wells) as to which the remediation cost set forth in the Environmental Defect Notice exceeds [***], and remediate the environmental condition affecting such Asset as Seller elects, or (ii) remediate one or more of the environmental conditions described in the Environmental Defect Notice. In such event, the Asset or Assets which are affected by the environmental conditions Sellers intend to remediate or which Sellers intend to retain shall not be conveyed to Purchaser at Closing, the Purchase Price shall be reduced by the aggregate allocated values of such Assets, and Sellers shall have a 30-day period within which to attempt to remediate such environmental conditions or confirm its decision to retain the specific Asset. If, at the end of such 30-day period, Sellers have remediated the environmental conditions to the reasonable satisfaction of Purchaser and otherwise in accordance with applicable law, Sellers shall convey the Assets affected thereby to Purchaser against delivery by Purchaser of an amount equal to the aggregate allocated values of such Assets. If, at the end of such 30-day period, Sellers have not remediated the environmental conditions to the reasonable satisfaction of Purchaser and still wish to convey the affected Asset, Purchaser shall have the right to elect (i) to acquire such Assets against delivery to Sellers of an amount equal to the difference between the aggregate allocated values of such Assets and the costs of remediating the environmental conditions affecting such Assets set forth in the Environmental Defect Notice (but not less than zero), or (ii) to reject such Assets and retain that portion of the Purchase Price equal to the aggregate allocated values of the affected Assets.

(d) Except to the extent otherwise required by law or judicial process, Purchaser shall exercise all due diligence in safeguarding and maintaining as confidential all data or information acquired during the Purchaser's Environmental Investigation. PURCHASER WAIVES AND RELEASES, AND AGREES TO DEFEND, INDEMNIFY AND SAVE AND HOLD HARMLESS sellerS, THEIR directors, officers, employees, CONTRACTORS and agents, against claims for injury to or death to persons or damage to property arising in any way from Purchaser's Environmental InSPECTION(S).

3.9 Environmental Inspection. - Purchaser represents that it has been, or by Closing will have been, afforded the full opportunity to conduct the Purchaser's Environmental Inspection and such other inspection of the environmental condition of the Assets as it desires.

3.10 NORM. - Purchaser acknowledges that a portion of the Assets have been used for exploration, development, production, gathering, compression and dehydration of oil and gas, and that there may be petroleum, produced water, wastes or other materials located on, under or associated with the Assets. Equipment and sites included in the Assets may contain asbestos, hazardous substances/materials, including hydrogen sulfide gas, or naturally occurring radioactive material ("NORM"). NORM may affix or attach itself to the inside of wells, materials and equipment as scale, or in other forms; the wells, materials and equipment located on or included in the Assets may contain NORM and other wastes or hazardous substances/materials; and NORM containing material and other wastes or hazardous substances/materials may have been buried, come in contact with the soil or otherwise been disposed of on or around the Assets. Special procedures may be required for the remediation, removal, transportation or disposal of wastes, asbestos, hazardous substances/materials, including hydrogen sulfide gas and NORM from the Assets. Purchaser shall control, store, handle, transport and dispose of, or discharge all materials, substances and wastes from the Assets (including produced water, hydrogen sulfide gas, drilling fluids, NORM and other wastes), whether present before or after the Effective Time, in a safe and prudent manner and in accordance with all applicable Environmental Laws (as defined below). Purchaser shall keep records of the types, amounts and location of materials, substances and wastes that are stored, transported, handled, discharged, released or disposed of onsite and offsite.

3.11 Environmental Releases and Indemnities.

(a) NOTWITHSTANDING ANY OTHER PROVISION OF THIS AGREEMENT, EFFECTIVE FROM THE SECOND ANNIVERSARY OF THE CLOSING DATE, PURCHASER AGREES TO INDEMNIFY, DEFEND, AND HOLD HARMLESS, SELLERS, THEIR OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, CONTRACTORS, REPRESENTATIVES, AFFILIATES, SUBSIDIARIES, SUCCESSORS AND ASSIGNS FROM AND AGAINST, ANY AND ALL LIABILITIES, CLAIMS, SUITS, AND COSTS AND EXPENSES (INCLUDING COURT COSTS, REASONABLE ATTORNEYS FEES AND EXPENSES OF EXPERTS) (COLLECTIVELY, "LOSSES") ARISING OUT OF OR WITH RESPECT TO ANY POLLUTION OR CONTAMINATION, OR THE ENVIRONMENTAL CONDITION, OF THE ASSETS OCCURRING OR EXISTING PRIOR TO, ON OR AFTER THE CLOSING DATE, OR ANY VIOLATION OF ANY ENVIRONMENTAL LAW RELATING TO THE ASSETS WHICH OCCURRED ON OR PRIOR TO THE CLOSING DATE, WHETHER OR NOT SUCH LOSS IS CAUSED BY OR ATTRIBUTABLE TO SELLERS' NEGLIGENCE; PROVIDED THAT PURCHASER SHALL HAVE NO INDEMNITY OBLIGATION UNDER THIS SECTION 3.11(a) FOR LOSSES ATTRIBUTABLE OR RELATING TO THE SELLER'S OFFSITE DISPOSAL OF CONTAMINATED SOIL, OR HAZARDOUS WASTES OR MATERIALS FROM THE ASSETS.

(b) NOTWITHSTANDING ANY OTHER PROVISION OF THIS AGREEMENT, EFFECTIVE FROM THE CLOSING, EXCEPT WITH RESPECT TO CLAIMS BASED UPON OR ARISING OUT OF SELLER'S OFFSITE DISPOSAL OF CONTAMINATED SOIL, OR HAZARDOUS WASTES OR MATERIALS FROM THE ASSETS AND AS OTHERWISE EXPRESSLY PROVIDED TO THE CONTRARY IN THIS AGREEMENT, PURCHASER RELEASES SELLERS FROM, AND COVENANTS AND AGREES NOT TO SUE, FOR CONTRIBUTION OR OTHERWISE, OR OTHERWISE MAKE OR FILE ANY CLAIM OF ANY NATURE AGAINST SELLERS, FOR OR BASED UPON ANY injury, illness or death of any person(s) or for OR BASED UPON ANY damage, loss, pollution or contamination of any real or personal property, ground water or the environment IN EACH CASE ATTRIBUTABLE TO OR ARISING OUT OF ANY VIOLATION BY SELLERS OF ANY Environmental Laws, OR ANY ENVIRONMENTAL CONDITION OF THE ASSETS, directly or indirectly from, or incident to, the use, occupation, ownership, operation, condition (whether latent or patent), maintenance or abandonment of any of the Assets AND WHETHER ARISING FROM OR CONTRIBUTED TO BY THE ACTIVE, PASSIVE, JOINT, SOLE OR CONCURRENT NEGLIGENCE, GROSS NEGLIGENCE OR STRICT LIABILITY OF SELLERS, OR SELLERS' CONTRACTORS OR SUBCONTRACTORS OR THE OFFICERS, DIRECTORS, AGENTS OR EMPLOYEES OF SELLERS' CONTRACTORS OR SUBCONTRACTORS, INCLUDING ANY STRICT LIABILITY UNDER ENVIRONMENTAL LAWS, REGARDLESS OF WHETHER ANY SUCH CLAIMS RESULT FROM ANY CONDITIONS, EVENTS, ACTIONS OR INACTIONS ARISING, OCCURRING OR OCCURRING PRIOR TO, ON OR AFTER THE EFFECTIVE TIME.

(c) For purposes of this Agreement, "Environmental Laws" shall mean any and all laws, statutes, regulations, rules, orders, ordinances, permits or determinations of any governmental authority pertaining to health, the environment, wildlife or natural resources in effect in or for the jurisdiction in which the Assets are located, including, without limitation, the Clean Air Act (Air Pollution Control Act), the Clean Water Act, the Federal Water Pollution Act, the Rivers and Harbors Act of 1899, the Safe Drinking Water Act, the National Environmental Policy Act of 1969 (NEPA), the Endangered Species Act, Fish and Wildlife Conservation Act of 1980, the Fish and Wildlife Coordination Act (FWCA), the Oil Pollution Act, the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA), the Superfund Amendments and Reauthorization Act of 1986 (SARA), the Resources, Conservation and Recovery Act (RCRA), the Toxic Substance Control Act, the Occupational, Safety & Health Act (OSHA), the Hazardous Materials Transportation Act, the Hazardous and Solid Waste Amendments of 1984 (HSWA), and any and all other past, present or future federal, state and local laws, statutes, regulations, rules, orders, ordinances, permits, licenses or determinations whose purpose is to conserve or protect health, the environment, wildlife or natural resources as any of the foregoing are now existing or may hereafter be amended or interpreted.

3.12 Casualty Loss. As used herein, the term "Casualty Loss" shall mean, with respect to all or any portion of any of the Assets, any damage or destruction by fire, blowout, storm or other casualty prior to Closing. Sellers shall promptly notify Purchaser of any Casualty Loss of which Sellers become aware. If any Casualty Loss occurs during the Adjustment Period, Purchaser may elect to (a) terminate this Agreement, but only in the event the aggregate allocated values of the affected Assets exceed 10% of the Purchase Price, (b) exclude the affected Assets from the transactions contemplated hereby and reduce the Purchase Price by the aggregate allocated values of such Assets, or (c) acquire such affected Assets notwithstanding such Casualty Loss, subject to Seller's agreement to transfer to Purchaser all unpaid insurance proceeds, claims, awards and other payments arising out of such Casualty Loss, and all amounts paid to Sellers as insurance proceeds, awards or other payment arising out of such Casualty Loss, plus the amount of any retention or deductible of Sellers.

Article IV

Certain Pre-Closing Actions

4.1 Access to Records. Between the date hereof and the Closing Date, Sellers shall give Purchaser and its representatives access to (a) the Records, (b) all information relating to the Assets that are in Sellers' possession or to which Seller is entitled and (c) Sellers' representatives with knowledge of the Assets. Such access by Purchaser shall be limited to Sellers' or such other party's normal business hours, upon reasonable advance notice, and shall be without material disruption of Sellers' normal and usual operations. In addition, Purchaser will have the right to copy, at Purchaser's expense, the Records. To the extent the Records and other information exist in electronic form, Sellers shall give Purchaser and its representatives access to review and analyze such electronic Records and other information. Sellers shall describe and show to the Purchaser the software containing the land and financial data and accounting. Upon Purchaser's request, J-W shall introduce Purchaser's representative to (i) J-W's computer technicians and (ii) the consulting company(ies) which provide J-W's land, accounting and database software so that, no later than the business day following the Closing, Purchaser may be able, at Purchaser's expense, to convert all of the Records and other information concerning the Assets into an electronic medium or media chosen by the Purchaser.

4.2 Independent Investigation, Related Indemnity and Disclaimer. Between the date hereof and the Closing Date, Purchaser will be afforded the opportunity to inspect the Assets and to conduct, at Purchaser's sole risk and expense, non-environmental onsite inspections, tests and inventories of the Assets.

Termination and Amendment

8.1 Termination. This Agreement may be terminated at any time prior to the Closing:

(a) by Purchaser or Sellers, upon written notice to the other, if Closing shall not have occurred on or before March 31, 2005 (the "Outside Closing Date") for any reason other than a breach or default by the terminating Party of its respective covenants, agreements or other obligations hereunder, or any of its representations herein not being true and accurate in all material respects when made or when otherwise required by this Agreement to be true and accurate in all material respects;

(b) at any time, by written agreement of Sellers and Purchaser; or

(c) by Purchaser or Sellers, upon written notice to the other, in the event the aggregate of the Title Defect Adjustment and Environmental Remediation Adjustment exceeds [***] of the Purchase Price.

8.2 Effect of Termination.

(a) If termination occurs pursuant to Sections 8.1(b) or (c), the Performance Deposit, plus all interest accrued thereon, shall be returned to Purchaser (and Sellers shall execute all instruments necessary to cause such return), and, except as provided in clause (b) below, neither Purchaser nor Sellers shall have any further obligation or liability under this Agreement.

(b) If termination occurs pursuant to Section 8.1(a), the Performance Deposit, plus all interest accrued thereon, shall be returned to Purchaser (and Sellers shall execute all instruments necessary to cause such return), and neither Purchaser nor Sellers shall have any further obligation or liability under this Agreement; provided, however, that if Sellers terminate this Agreement under Section 8.1(a) due to Purchaser's inability or failure to close the transactions contemplated herein, and (i) all of the conditions set forth in Section 7.2 hereof have been satisfied and (ii) Sellers are not then in breach or default of their respective covenants, agreements or obligations herein and all of their representations are then true and accurate, Sellers may retain the Performance Deposit and all interest accrued thereon as liquidated damages and not a penalty (and Purchaser shall execute all instruments necessary to allow such retention), and as Sellers' sole and exclusive remedy for Purchaser's default; and provided, further, that if Purchaser terminates this Agreement under Section 8.1(a) due solely to Sellers' inability of failure to close the transactions contemplated herein, and (iii) all of the conditions set forth in Section 7.1 have been satisfied and (iv) Purchaser is not then in breach or default of its respective covenants, agreements or obligations herein and all of its representations are then true and accurate, Purchaser may seek specific performance of Sellers' obligations hereunder as Purchaser's sole and exclusive remedy for Sellers' default.

(c) If termination occurs due to a failure to satisfy the closing condition set forth in Section 7.2(h) hereof, and such failure is not attributable to an act or omission of any Seller, then upon such termination Sellers may retain the Performance Deposit and all interest accrued thereon (and Purchaser shall execute all instruments necessary to allow such retention).

The provisions of Section 8.2 shall survive any termination of this Agreement.

Article IX

9.2 Further Assurances. After Closing, Sellers and Purchaser shall execute, acknowledge and deliver or cause to be executed, acknowledged and delivered such instruments and take such other action including payment of monies as may be necessary or advisable to carry out their obligations under this Agreement and under any document, certificate or other instrument delivered pursuant hereto or required by law.

9.3 Purchaser's Post-Closing Obligations.

It is the intention of the Parties that all accounts receivable (or similar obligations) attributable to sales subsequent to the Effective Time shall belong to the Purchaser and, accordingly, Sellers agree to participate in any joint notice from Sellers to the account debtors instructing them to make all payments on such obligations directly to the Purchaser and to exercise all reasonable efforts to help Purchaser collect such obligations.

9.7 Waiver of DTPA It is the intent of the Parties that Purchaser's rights and remedies with respect to the transactions contemplated by this Agreement and with respect to all acts or practices of Sellers, past, present or future, in connection with the transactions contemplated by this Agreement shall be governed by legal principles other than the Texas Deceptive Trade Practices - Consumer Protection Act, Tex. Bus. & Ann.  Section 17.41 et seq. (Vernon 1987 and Supp. 1994) (the "DTPA") or any similar statute of any jurisdiction that may be applicable to the transactions contemplated hereby. As such, Purchaser hereby waives the applicability of the DTPA or any similar statute to this transaction and any and all duties, rights or remedies that might be imposed by the DTPA or any similar statute; provided, however, Purchaser does not waive Section 17.555 of the DTPA. Purchaser acknowledges, represents and warrants that it is purchasing the Assets covered by this Agreement for commercial or business matters; that it is able to evaluate the merits and risks of a transaction such as this; and that it is not in a significantly disparate bargaining position with Sellers. Purchaser expressly recognizes that the price for which Sellers have agreed to sell the Assets and perform its obligations under this Agreement has been predicated upon the inapplicability of the DTPA or any similar statute and this waiver of the DTPA and any similar statute. Purchaser further recognizes that Sellers, in determining to proceed with the entering into of this Agreement have expressly relied on the provisions of this Section 9.7.

Pursuant to Section 2.4(b)(viii), the Purchase Price shall be adjusted downward in an amount equal to all suspensed funds including interest in the Suspense Accounts described in Schedule 5.13. Sellers shall indemnify and hold Purchaser harmless against any and all Losses associated with any suspensed funds in the Suspense Accounts attributable to the period of time prior to the Effective Time, to the extent such Losses exceed the amount by which the Purchase Price was adjusted pursuant to Section 2.4(b)(viii). Purchaser shall be responsible for distributing the suspensed funds plus interest in the Suspense Accounts.

9.11 Royalty and Rental Payment Obligations. Upon the request of Purchaser, Sellers shall, during a period ending no later than the 90th day following the Closing Date, continue to timely and properly make all royalty and rental payments due and payable after the date hereof with respect to the Leases or Wells; provided that Purchaser shall (a) reimburse Sellers in full for all such royalty and rental payments to the extent they relate to periods of time after the Effective Time, and (b) pay Sellers $25,000.00 per month, payable in advance on the first day of each month after the Closing during which Sellers perform such payment services for Purchaser's account (collectively, the "Royalty Payment Amount"). Purchaser shall reimburse Seller for all actual costs for checks, mailing costs, envelopes and other third party costs related to such payment situations.

9.12 Sellers' Covenant Not to Compete. For a period of two (2) years after the Closing, no Seller nor any of its Affiliates shall, either acting alone or in concert with others, directly or indirectly, purchase, lease or otherwise acquire any working, mineral, royalty or other oil and gas interest of any kind within two (2) miles of any Lease or mineral interest included in the Assets; provided that such restrictions shall not apply to any acquisition by any Seller or its Affiliates pursuant to a merger or consolidation or of all or substantially all of the assets of another Person.
