Price.  The total consideration for the purchase, sale, and
conveyance of the Assets to Buyer and Buyer’s assumption of the Assumed
Obligations and all other liabilities provided for in this Agreement, is Buyer’s
payment to Seller of the sum of One Hundred Thirty Million Dollars
($130,000,000.00) (the “Purchase Price”), as
adjusted in accordance with the provisions of this Agreement.

           

          Section
2.02                      Deposit.

           

          (a)           Concurrently
with the execution of this Agreement by Buyer and Seller, Buyer shall deliver to
Seller in immediately available funds a performance guarantee deposit in an
amount equal to(5 percent of the Purchase
Price)  (the “Deposit”) in
accordance with wire transfer instructions provided by Seller to
Buyer.

           

          (b)           Subject
to the proviso set forth in 
Section 11.01, if
this Agreement is terminated by Seller pursuant to 
Section 11.01(b)
and Seller does not waive the non-satisfaction of any conditions to Closing set
forth in 
Article 8, Seller
shall retain the Deposit as liquidated damages, which remedy shall be the sole
and exclusive remedy available to Seller for Buyer’s failure to perform its
obligations under this Agreement. Buyer and Seller acknowledge and agree that
(i) Seller’s actual damages upon the event of such a termination are
difficult to ascertain with any certainty, (ii) the Deposit is a reasonable
estimate of such actual damages, and (iii) such liquidated damages do not
constitute a penalty.  Provided, however, that if this Agreement is
terminated by Seller pursuant to Section 11.01(b)
pursuant to Section 8.03, and the threatened or pending suit, action or other
proceeding described therein was not threatened or initiated by Buyer, Seller
shall promptly return the Deposit to Buyer in immediately available funds
pursuant to wire transfer instructions to be provided timely by Buyer to Seller
within three (3) business days after the event giving rise to such return
obligation.

           

          (c)           Subject
to the proviso set forth in 
Section 11.01, if
this Agreement is terminated (i) by Buyer pursuant to

all conditions precedent to the obligations of Seller set forth in 
Article 8 have
been met, then notwithstanding any provision in this 
Section 2.02 to
the contrary, if Closing does not occur because Seller wrongfully fails to
tender performance at Closing or otherwise Breaches this Agreement in any
respect prior to Closing, and Buyer is ready and otherwise able to close, at
Buyer’s sole election, either (i) Seller shall return the Deposit to Buyer
within three (3) business days after the determination that the Closing will not
occur, or (ii) Buyer shall have the right to pursue specific performance of this
Agreement, provided that Buyer must file an action for specific performance
within 21 days of Seller’s Breach.  If Buyer elects to pursue specific
performance, Buyer must pursue specific performance as its sole and exclusive
remedy in lieu of all other legal and equitable remedies.  If such
action for specific performance is not filed within 21 days of Seller’s Breach
or if Buyer is unsuccessful for any reason other than a Breach of this Agreement
by Buyer, Buyer shall be deemed to have waived all legal and equitable remedies
and its sole remedy for Seller’s Breach of this Agreement shall be limited to
the prompt return of the Deposit and the termination of this
Agreement.

           

          Section
2.03                      Allocated
Values.  The Purchase Price is allocated among the Assets
(including the Wells, PUD Locations, PDNP, and Probable and/or Possible
Locations) as set forth in Exhibit D (the “Allocated Values”).
In no event shall the aggregate of the Allocated Values of the Units, Wells, PUD
Locations, PDNP, Probable and/or Possible Locations, and any other item
specified on Exhibit
D (such as undeveloped leasehold) (with all such items specifically set
forth on Exhibit
D being referred to herein as the “Allocated Assets” or as to any single
specified item, an “Allocated Asset”) exceed the unadjusted Purchase Price. The
term “Unit” means any governmentally approved unit specifically referenced in
Exhibit
D.  The term “PUD Locations” means
those Proved Undeveloped potential well locations specifically identified in
Exhibit D.  The
term “PDNP”
means Proved Developed Not Producing intervals as specifically identified on
Exhibit D. The
term “Probable and/or
Possible Locations”  means those locations specifically
identified and designated as such on Exhibit
D.  Seller and Buyer agree that the Allocated Values shall be
used to compute any adjustments to the Purchase Price pursuant to the provisions
of 
Article
4.  Any adjustment to the Purchase Price hereunder shall be
reflected in the allocation set forth in Exhibit D consistent
with Treasury Regulation Section 1.1060-1T(f). For tax purposes, the
Parties agree to report the transactions contemplated by this Agreement in a
manner consistent with the terms of this Agreement, including the allocations
set forth above as of the Closing Date, and that neither Party will take any
position inconsistent therewith, including in any tax return, refund claim,
litigation, arbitration, or otherwise.

          Section
2.04                      Section 1031
Like-Kind Exchange.  Seller
and Buyer hereby agree that Seller shall have the right at any time prior to
completion of all the transactions that are to occur at Closing to assign all or
a portion of its rights under this Agreement to a Qualified Intermediary (as
that term is defined in Section 1.1031(k)-1(g)(4)(v) of the Treasury
Regulations) in order to accomplish the transaction in a manner that will
comply, either in whole or in part, with the requirements of a like-kind
exchange pursuant to Section 1031 of the Internal Revenue Code of 1986, as
amended. Likewise, Buyer shall have the right at any time prior to completion of
all the transactions that are to occur at Closing to assign all or a portion of
its rights under this Agreement to a Qualified Intermediary for the same
purpose. If Seller assigns all or any of its rights under this Agreement for
this purpose, Buyer agrees to (a) consent to Seller’s assignment of its rights
in this Agreement, which assignment shall be in a form reasonably acceptable to
Buyer, and (b) pay the Purchase Price (or a designated portion thereof as
specified by Seller) into a qualified escrow or qualified trust account at
Closing as directed in writing. If Buyer assigns all or any of its rights under
this Agreement for this purpose, Seller agrees to (i) consent to Buyer’s
assignment of its rights in this Agreement, which assignment shall be in a form
reasonably acceptable to Seller, (ii) accept the Purchase Price from the
qualified escrow or qualified trust account at Closing, and (iii) at Closing,
convey and assign directly to Buyer the Assets (or any portion thereof) as
directed by Buyer. Seller and Buyer acknowledge and agree that any assignment of
this Agreement  (or any rights hereunder) to a Qualified Intermediary
shall not release any Party from any of its respective liabilities and
obligations hereunder, and that neither Party represents to the other Party that
any particular tax treatment will be given to any Party as a result
thereof.  The Party electing to assign all or any of its rights under
this Agreement pursuant to this 
Section 2.04
shall defend, indemnify, and hold harmless the other Party and its Affiliates
from all Claims relating to such election.

Imbalances.

           

          (a)           Assumption of Production
Imbalances Upon Closing.  Buyer shall assume the positions of
Seller with respect to all gas imbalances and make-up obligations related to the
Assets regardless of whether such imbalances or make-up obligations arise before
or after the Effective Time, at the wellhead, pipeline, gathering system, or
other location, and regardless of whether the same arise under contract or
otherwise (“Production
Imbalances”). As a result of such assumption, Buyer shall (a) be entitled
to receive any and all benefits which Seller would have been entitled to receive
by virtue of its position, including rights to produce and receive volumes of
production in excess of volumes which it would otherwise have been entitled to
produce and to receive cash gas balancing by virtue of ownership of the Assets,
(b) be obligated to suffer any detriments or losses which Seller would have been
obligated to suffer by virtue of such position, including the obligation to
deliver to others production volumes which would have otherwise been
attributable to its ownership of the Assets, to deliver production to purchasers
thereof without Buyer receiving full payment therefor, or to make cash balancing
payments or to repay any take or pay payments, and (c) be responsible for any
and all royalty obligations and other burdens with respect to such Production
Imbalances; provided however, nothing in this subsection (a) of 
Section 3.02
shall relieve Seller from any royalty obligation affecting production Seller has
actually received for production occurring prior to the Effective
Time.

Period.  Until 5:00 p.m. MST on the date which is seven (7)
days prior to the Closing Date (the “Examination Period”),
Seller shall permit Buyer and/or its representatives to examine during normal
business days and hours at a location designated by Seller, all abstracts of
title, title opinions, title files, ownership maps, lease, Well and division
order files, assignments, operating, and accounting records and all Surface
Agreements, Permits, Contracts, and other agreements, data, analyses, and
information pertaining to the Assets insofar as same may now be in existence and
in the possession of Seller, subject to such restrictions upon disclosure as may
exist under confidentiality or other agreements binding upon Seller and relating
to such data.

           

          Section
4.02                      Title
Defects.  The term “Title Defect” means
(a) any encumbrance on, encroachment on, irregularity in, defect in, or
objection to Seller’s ownership of the Assets (excluding Permitted Encumbrances)
that causes Seller not to have Marketable Title to an Allocated Asset; or (b)
any default by Seller under a lease, farm-out agreement, or other contract or
agreement that would (i) have a material and adverse effect on the operation,
value, or use of such Asset, (ii) prevent Seller from receiving the proceeds of
production attributable to Seller’s interest therein, or (iii) result in
cancellation of all or a portion of Seller’s interest therein. The term “Marketable Title”
means such ownership by Seller in the Assets  that, subject to and
except for the Permitted Encumbrances:

           

          (a)           entitles
Seller to receive not less than the percentage set forth in Exhibit D as Seller’s
Net Revenue Interest of all Hydrocarbons produced, saved, and marketed from such
Allocated Asset , all without reduction, suspension, or termination of such
interest throughout the productive life of such Well, except as specifically set
forth in such exhibit;

           

          (b)           obligates
Seller to bear not greater than the percentage set forth in Exhibit D as
Seller’s Working Interest of the costs and expenses relating to the maintenance,
development, and operation of such Allocated Asset, all without increase
throughout the productive life of such Well, except as specifically set forth in
such exhibit; and

           

          (c)           is
free and clear of all liens, encumbrances, and defects in title.

           

          Subject
to the limitations of 
Section 4.14,
Breaches of Seller’s representations and warranties contained in 
Section 5.07
through 
Section 5.24
discovered prior to the Closing shall be treated as Title Defects for purposes
of making pre-Closing adjustments to the Purchase Price.

          Section
4.03                      Notice of Title
Defects.  Buyer shall provide Seller notice of all Title
Defects no later than 5:00 p.m. MST on the date which is seven (7) days prior to
the Closing Date (the “Title Claim Date”).
To be effective, such notice must (a) be in writing, (b) be received by Seller
on or prior to the Title Claim Date, (c) describe the Title Defect in reasonable
detail (including any alleged variance in the Net Revenue Interest or Working
Interest), (d) identify the specific Asset or Assets affected by such Title
Defect, (e) include the Title Defect Value, as reasonably determined by Buyer in
good faith, and (f) comply with the limitations and Title Defect Value
qualifications set forth in 
Section 4.14. Any
matters identified by Buyer during the Examination Period that constitute Title
Defects, but of which Seller has not been specifically notified by Buyer in
accordance with the foregoing, shall be deemed to have been waived by Buyer for
all purposes and shall constitute Permitted Encumbrances and Assumed Obligations
hereunder. Upon receipt of notices of Title Defects, the Parties shall meet and
determine upon which of the Title Defects, Title Defect Values, and methods of
cure the Parties have reached agreement. Upon the receipt of such notice from
Buyer, Seller shall have the option, but not the obligation, for a period ending
ninety (90) days after the Closing to cure such defect. If Seller should not
elect to cure a Title Defect, and no aspect of such defect is reasonably in
dispute, the Purchase Price shall be adjusted for such defect by the amount of
the Title Defect Value.

           

          (a)           The
value attributable to each Title Defect (the “Title Defect Value”)
that is asserted by Buyer in the Title Defect notices shall be determined based
upon the criteria set forth below:

           

          (i)           If
the Title Defect is a lien upon any Asset, the Title Defect Value is the amount
necessary to be paid to remove the lien from the affected Asset;

           

          (ii)           If
the Title Defect asserted is that the Net Revenue Interest attributable to any
Allocated Asset is less than that stated in Exhibit D, then
the Title Defect Value shall be the absolute value of the number determined by
the following formula:

           

          Title
Defect Value  = A  x  (1-[B/C])

           

          A  =
Allocated Value for the affected Asset

           

          B  =
Correct Net Revenue Interest for the affected Asset

           

          
            
              
              

            

            
              11

              
                

              

            

            
              
              

            

          

           

          C  =
Net Revenue Interest for the affected Asset as set forth on Exhibit
D.

           

          (iii)           If
the Title Defect represents an obligation, encumbrance, burden, or charge upon
the affected Asset (including any increase in Working Interest for which there
is not a proportionate increase in Net Revenue Interest) for which the economic
detriment to Buyer is unliquidated, the amount of the Title Defect Value shall
be determined by taking into account the Allocated Value of the affected Asset,
the portion of the Asset affected by the Title Defect, the legal effect of the
Title Defect, the potential discounted economic effect of the Title Defect over
the life of the affected Asset, and the Title Defect Value placed upon the Title
Defect by Buyer and Seller;

           

          (iv)           If
a Title Defect is not in effect or does not adversely affect an Asset throughout
the entire post Effective Time productive life of such Asset, such fact shall be
taken into account in determining the Title Defect Value;

           

          (v)           The
Title Defect Value of a Title Defect shall be determined without duplication of
any costs or losses included in another Title Defect Value
hereunder;

           

          (vi)           Notwithstanding
anything herein to the contrary, in no event shall a Title Defect Value exceed
the Allocated Value of the Allocated Asset affected thereby;

           

          (vii)           If
the Title Defect Value of an Asset is equal to the Allocated Value of such
Asset, the affected Asset shall remain in the purchase and sale contemplated by
this Agreement, but the Purchase Price shall be adjusted
accordingly;

           

          (viii)           Notwithstanding
the provisions of this 
Section 4.03 to
the contrary, the Title Defect Value of any Title Defect comprising a required
consent not obtained (other than consents customarily obtained after Closing)
shall be determined subject to any accommodation implemented pursuant to 
Section 4.07;
and

           

          (ix)           Such
other factors as are reasonably necessary to make a proper
evaluation.

          (b)           The
term Title Defect shall not include:

           

          (i)           Defects
based solely on an assertion that Seller’s files lack information, provided that
any missing material information can be obtained by the reasonable efforts of
Buyer;

           

          (ii)           Defects
in the early chain of title consisting of the failure to recite marital status
in a document or omissions of successors of heirship or estate proceedings,
unless Buyer provides a reasonable basis for the assertion that such failure or
omission has resulted in a third party’s actual and superior claim of title to
the affected Asset;

           

          (iii)           Defects
arising out of lack of survey;

           

          (iv)           Defects
arising out of lack of corporate or other entity authorization unless Buyer
provides a reasonable basis for the assertion that the action was not authorized
and that such lack of authorization has resulted in a third party’s actual and
superior claim of title to the affected Asset;

           

          (v)           Defects
asserting a change in an applicable Working Interest or Net Revenue Interest
based on a change in drilling and spacing units, tract allocation or other
changes in pooling or unit participation occurring after the date of this
Agreement; and

           

          (vi)           Title
requirements customarily considered as advisory or which can be waived as a
matter of prudent business judgment.

           

          Section
4.04                      Remedies for Title
Defects.

           

          (a)           For
any Title Defect noticed pursuant to 
Section 4.03 that
has not been cured at or prior to Closing, the Purchase Price shall, subject to
the provisions of 
Section 4.14, be
decreased at Closing by either (i) the amount the Parties acting reasonably and
in good faith agree in lieu of a cure of the asserted Title Defect, or (ii) with
respect to any Title Defect for which the Parties have not yet agreed as to the
validity of the Title Defect, the Title Defect Value, or the manner of cure,
then by the amount of the Title Defect Value asserted by Buyer for such uncured
or unadjusted Title Defect.

           

          (b)           Notwithstanding
anything to the contrary in this 
Section 4.04, if
any Title Defect is in the nature of a consent to assignment that is not
obtained or other restriction on assignment, the provisions of 
Section 4.07
shall apply.

           

          
            
              
              

            

            
              13

              
                

              

            

            
              
              

            

          

           

          (c)           If
at the expiration of thirty (30) days after Closing, the Parties have not agreed
upon the validity of any asserted Title Defect, the appropriate cure of the
same, or the Title Defect Value attributable thereto, either Party shall have
the right to elect to have any such dispute determined by an Independent Expert
pursuant to 
Section
4.13.

           

          (d)           Once
a Title Defect is cured by Seller at its sole cost and expense to Buyer’s
reasonable satisfaction, or the existence or value of the Title Defect is
determined with finality either by agreement between the affected Parties or in
accordance with Section 4.13, Buyer
shall promptly pay to Seller (i) in the case of a Title Defect which is cured,
the amount the Purchase Price was decreased at Closing as a result of this
previously uncured Title Defect or (ii) in the case of an Asset affected by an
unresolved Title Defect and for which the validity of the Title Defect or the
Title Defect Value is determined with finality whether by agreement or in
accordance with Section 4.13, the
difference, if any, between the amount the Purchase Price was decreased at
Closing as a consequence of such  asserted and unresolved Title Defect
and the amount determined with finality.

           

          Section
4.05                      Special Warranty of
Title.  The documents to be executed and delivered by Seller to
Buyer, transferring title to the Assets as required hereby, including the
Assignment and Bill of Sale the form of which (subject to modification to meet
state recording statute requirements) is attached hereto as Exhibit E (the “Assignment”), shall
provide for a special warranty of title, by, through, and under Seller, subject
to the Permitted Encumbrances and the terms of this Agreement. The term “Permitted

Seller has agreed to retain or pay pursuant to the terms hereof, or (B) for
which Seller is responsible for paying or releasing at the Closing, and (ii)
liens of materialmen, mechanics, repairman, employees, contractors, or
operators, or other similar liens or charges for liquidated amounts arising in
the ordinary course of business (A) that Seller has agreed to retain or pay

or releasing at the Closing;

           

          
            
              
              

            

            
              14

              
                

              

            

            
              
              

            

          

           

          (b)           any

being contested in good faith in the ordinary course of business and for which
Seller has agreed to pay pursuant to the terms hereof or which have been
prorated pursuant to the terms hereof;

to secure compliance with the terms of) the Contracts, Surface Agreements,
Leases, and any other agreements, instruments, documents, and other matters
described or referred to in any Exhibit or Schedule hereto, or other terms in
such instruments that create or reserve to Seller its interest in the Assets;
provided, that, such matters do not operate to (i) reduce the Net Revenue
Interest of Seller in any Allocated Asset as reflected in Exhibit D, or
(ii) increase the proportionate share of costs and expenses of leasehold
operations attributable to or to be borne by the Working Interest of Seller with
respect to any Allocated Asset as reflected in Exhibit D,
unless there is a proportionate increase in Seller’s applicable Net Revenue
Interest;

           

          (d)           any
obligations or duties affecting the Assets to any Governmental Authority with
respect to any franchise, grant, license, or permit, and all applicable federal,

          (f)           all
royalties, overriding royalties, net profits interests, carried interests,
production payments, reversionary interests, and other burdens on or deductions
from the proceeds of production created or in existence as of the Effective
Time, whether recorded or unrecorded, that do not (i) reduce the Net Revenue
Interest of Seller in any Allocated Asset and as reflected in Exhibit D, or (ii)
increase the proportionate share of costs and expenses of leasehold operations
attributable to or to be borne by the Working Interest of Seller with respect to
any Allocated Asset as reflected in Exhibit D, unless
there is a proportionate increase in Seller’s applicable Net Revenue
Interest;

          (g)           preferential
rights to purchase or similar agreements (i) with respect to which (A) waivers
or consents are obtained from the appropriate parties for the transaction
contemplated hereby, or (B) required notices have been given for the transaction

asserting such rights has expired without an exercise of such rights, or (ii)
not exercised prior to Closing, subject to 
Section
4.06;

           

          (h)           required

the transaction contemplated hereby to the holders of such rights and the
appropriate period for asserting such rights has expired without an exercise of
such rights;

           

          (i)           all
rights to consent by, required notices to, filings with, or other actions by,
Governmental Authorities in connection with the sale, transfer, or conveyance of
the Assets that are customarily obtained after such sale or
conveyance;

          (k)           rights
reserved to or vested in any Governmental Authority to control or regulate any
of the Wells or units included in the Assets and the applicable laws, rules, and

operations attributable to or to be borne by the Working Interests of Seller
with respect to any Allocated Asset as reflected on Exhibit D unless

Closing as provided in 
Section
9.04.

           

          Section
4.06                      Preferential Rights to
Purchase.

           

          (a)           After
consultation with Buyer, Seller shall use its reasonable efforts, but without
any obligation to incur anything but reasonable costs and expenses in connection
therewith, to comply with all preferential right to purchase provisions relative
to any Asset prior to the Closing, including those rights of preferential
purchase identified on Schedule
4.06.

           

          (b)           Prior
to the Closing, Seller shall promptly notify Buyer if any of such preferential
purchase rights are exercised or if the requisite period has elapsed without
such rights having been exercised.

          (c)           If
a third party who has been offered an interest in any Asset pursuant to a
preferential right to purchase elects prior to the Closing to purchase all or
part of such Asset, and the closing of such transaction occurs on or before the
Closing Date, then the Asset or part thereof so affected will be eliminated from
the Assets and the Purchase Price shall be reduced by the Allocated Value of
such Asset. If any such third party has elected to purchase all or a part of an
interest in any Asset subject to a preferential right to purchase, but has
failed to close the transaction by the Closing Date, then all of the Assets will
be conveyed to Buyer at Closing, without adjustment to the Purchase Price, and
on the Closing Date, Buyer shall, as an Assumed Obligation, assume all duties,
obligations, and liabilities, of any kind or nature, arising from, out of, or in
connection with, any enforceable preferential right to purchase that is
outstanding, and, if exercised, Buyer shall receive the payment therefor and
shall assign the affected portion of the Assets to the holder of such exercised
preferential right to purchase. In addition, in the event an interest is offered
by Seller pursuant to a preferential right to purchase for which notice has been
given but the time period for response by the holder of such right extends
beyond Closing, such interest shall be conveyed to Buyer at the Closing, without
reduction to the Purchase Price, and shall be subject to such preferential right
of purchase.

           

          Section
4.07                      Consents to
Assignment.  If any Asset is subject to a Title Defect as a
result of a consent to assignment not having been obtained, including those
consents to assignment set forth on Schedule 4.07, or, of
the existence of other restrictions on assignment or conveyance, Buyer and
Seller shall cooperate in any reasonable and lawful arrangement proposed to
provide Buyer with the benefits of ownership of the affected Asset without
breaching the consent requirement or restriction comprising such Title
Defect.  If such consent is obtained or such restriction eliminated
following the Closing, then Seller shall execute and deliver to Buyer an
assignment of Seller’s retained title and any related obligations consistent
with the terms of this Agreement.  Provided, however, that Buyer shall
not be obligated to enter into any arrangement whereby Seller retains actual
title with beneficial title being assigned to Buyer at the Closing unless Seller
can demonstrate to Buyer’s reasonable satisfaction that such consent to
assignment will be obtained or such restriction eliminated within ninety (90)
days after the Closing.  If Seller cannot demonstrate to Buyer’s
reasonable satisfaction that such consent to assignment will be obtained or such
restriction shall be eliminated within ninety (90) days after the Closing, such
consent to assignment or restriction shall be treated for all purposes as a
Title Defect.

          Section
4.08                      Remedies for Title
Benefits.

           

          (a)           If
Buyer discovers any Title Benefit affecting the Assets, it shall promptly notify
Seller in writing thereof. Subject to 
Section 4.14,
Seller shall be entitled to an upward adjustment to the Purchase Price with
respect to all Title Benefits in an amount (the “Title Benefit Value”)
determined in accordance with the formula provided for in this 
Section
4.08(a).  The term “Title Benefit” shall mean
Seller’s Net Revenue Interest in any Allocated Asset that is greater than or in
addition to the Net Revenue Interest set forth in Exhibit D, or
Seller’s Working Interest in any Allocated Asset that is less than the Working
Interest set forth in Exhibit D
(without a proportionate decrease in the Net Revenue Interest). The Title
Benefit Value shall be the absolute value of the number determined by the
following formula:

           

          Title
Benefit Value  = [A  x  (B/C)] - A

           

          A  =
Allocated Value for the affected Asset

           

          B  =
Correct Net Revenue Interest for the affected Asset

           

          C  =
Net Revenue Interest for the affected Asset as set forth on Exhibit
D.

           

          (b)           If
the Title Benefit represents a decrease in Working Interest for which there is
not a proportionate decrease in Net Revenue Interest, the amount of the Title
Benefit Value shall be determined by taking into account the Allocated Value of
the affected Asset, the portion of the Asset affected by the Title Benefit, the
legal effect of the Title Benefit, the potential discounted economic effect of
the Title Benefit over the post Effective Time life of the affected Asset, and
the Title Benefit Values placed upon the Title Benefit by Buyer and
Seller.

           

          (c)           If
the Parties have not agreed on the amount of the Title Benefit Value of a Title
Benefit by the expiration of thirty (30) days after Closing, Seller or Buyer
shall have the right to elect to have such Title Benefit Value determined by an
Independent Expert pursuant to 
Section 4.13. If
the Title Benefit Value is not determined pursuant to this Agreement by the
Closing, the Purchase Price paid at Closing shall be increased, subject to 
Section 4.14, by
the Title Benefit Value determined by Seller, acting reasonably and in good
faith.  Upon the final determination of Title Benefit Value either by
mutual agreement of the Parties or by the Independent Expert, (i) Seller
shall refund to Buyer the amount, if any, by which the amount so paid by Buyer
at Closing exceeds such Title Benefit Value, or (ii) Buyer shall pay to
Seller the amount, if any, by which such Title Benefit Value exceeds the amount
so paid by Buyer at Closing.

           

          
            
              
              

            

            
              19

              
                

              

            

            
              
              

            

          

           

          Section
4.09                      Environmental
Review.  Buyer may conduct an environmental assessment of the
Assets prior to the expiration of the Title Claim Date, subject to the
following:

           

          (a)           Buyer
shall have the right to conduct a Phase I (as that term is defined by the
American Society for Testing and Materials) environmental review of the Assets
prior to the expiration of the Examination Period (“Buyer’s Environmental
Review”) and Seller shall provide to Buyer a copy of any environmental
review Seller has in its possession subject to the same terms of confidentiality
subsequently set forth herein;

           

          (i)           The
cost and expense of Buyer’s Environmental Review shall be borne solely by
Buyer;

           

          (ii)           All
inspections must be coordinated through a designated representative of Seller
who may accompany Buyer during the course of Buyer’s inspection of the
Assets;

           

          (iii)           All
environmental assessments shall be conducted by an independent environmental
consultant engaged by Buyer at Buyer’s expense;

           

          (iv)           Buyer
shall give Seller notice not more than seven (7) days and not less than forty
eight (48) hours before any visits by Buyer and/or its consultant to the Assets,
and Buyer shall seek and obtain Seller’s prior consent (which shall not be
unreasonably withheld) before either it or its consultant enters the
Assets;

           

          (v)           Buyer
shall provide Seller a copy of the Phase I report affecting the Assets promptly
after Buyer’s receipt of the same;

           

          (vi)           Buyer
shall give Seller prompt written notice and obtain Seller’s prior written
consent (not to be unreasonably withheld) if Buyer desires to conduct a Phase II
(as that term is defined by the American Society for Testing and Materials)
study based on the recommendations of Buyer’s independent environmental
consultant (acting reasonably) with respect to the Assets.  With
respect to any samples taken in connection with Buyer’s Environmental Review,
Buyer shall take split samples, providing one of each such sample, properly
labeled and identified, to Seller;

          (vii)           Buyer
and/or its consultant shall perform all such work in a safe and workmanlike
manner, shall not unreasonably interfere with Seller’s operations, and shall
comply with all Laws of applicable Governmental Authorities;

           

          (viii)           Buyer
shall be primarily responsible for obtaining any third party consents that are
required in order to perform any work comprising Buyer’s Environmental Review,
and Buyer shall consult with Seller prior to requesting each such third party
consent;  provided, however, that Seller shall cooperate with Buyer
(at no out of pocket cost to Seller) in Buyer’s efforts to obtain any third
party consents required to perform any work comprising Buyer’s Environmental
Review; and

           

          (ix)           Buyer
hereby agrees to release and defend, indemnify and hold harmless Seller and
Seller’s Representatives from and against all Claims made by (or attributable to
the acts or omissions of) Buyer or Buyer’s Representatives (INCLUDING THOSE RESULTING FROM THE
SOLE, JOINT, OR CONCURRENT NEGLIGENCE (BUT NOT GROSS NEGLIGENCE OR WILLFUL
MISCONDUCT), STRICT LIABILITY OR OTHER LEGAL FAULT OF SELLER OR ANY OF SELLER’S
REPRESENTATIVES) arising out of or
relating to Buyer’s Environmental Review. The release and indemnity provisions
of this 
Section 4.09
shall survive termination or Closing of this Agreement notwithstanding anything
to the contrary provided for in this Agreement.

           

          (b)           Unless
otherwise required by applicable Laws, Buyer shall treat any matters revealed by
Buyer’s Environmental Review and any environmental review provided by Seller to
Buyer, including any analyses, compilations, studies, documents, reports, or
data prepared or generated from such review (the “Environmental
Information”), as confidential, and, except as provided below, Buyer
shall not disclose any Environmental

          Information
to any Governmental Authority or other third party without the prior written
consent of Seller. Buyer may use the Environmental Information only in
connection with the transactions contemplated by this Agreement. The
Environmental Information shall be disclosed by Buyer to only those persons who
need to know the Environmental Information for purposes of evaluating the
transaction contemplated by this Agreement, and who agree to be bound by the
terms of this 
Section 4.09. If
Buyer or any third party to whom Buyer has provided any Environmental
Information is requested, compelled, or required to disclose any of the
Environmental Information, Buyer shall provide Seller with prompt notice
sufficiently prior to any such disclosure so as to allow Seller to file for any
protective order, or seek any other remedy, as it deems appropriate under the
circumstances. If this Agreement is terminated prior to the Closing, upon
Seller’s request Buyer shall deliver the Environmental Information, and all
copies thereof and works based thereon, to Seller, which Environmental
Information shall become the sole property of Seller. Upon request, Buyer shall
provide copies of the Environmental Information to Seller without charge. The
terms and provisions of this 
Section 4.09(b)
shall survive any termination of this Agreement, notwithstanding anything to the
contrary.

           

          Section
4.10                      Definitions Used in

Article 4 and in this
Agreement.

           

          (a)           Environmental
Defects. The term “Environmental Defect”
shall mean, with respect to any given Asset, a violation of Environmental Laws
in effect as of the Effective Time in the jurisdiction in which such Asset is
located.  For the purpose of determining whether or not the
Environmental Defect Value threshold for a given Environmental Defect has been
met as required in Section 4.14(a), all
Environmental Defects affecting any particular Well or any discrete Facility may
be aggregated into a single Environmental Defect.  It is not intended
that this aggregation concept shall apply to the entirety of any particular Unit
described in Exhibit
D.

           

          (b)           Governmental
Authority. The term “Governmental
Authority” shall mean the United States and any state, county, city, and
political subdivisions that exercises jurisdiction, and any agency, department,
board, commission, or other instrumentality thereof.

           

          
            
              
              

            

            
              22

              
                

              

            

            
              
              

            

          

           

          (c)           Environmental Laws.
The term “Environmental Laws”
shall mean any and all laws, statutes, ordinances, rules, regulations, or orders
of any Governmental Authority pertaining to health and natural resources (but
excluding laws, orders, rules, and regulations that pertain to the prevention of
waste or the protection of correlative rights) and the protection of wildlife or
the environment including, without limitation, the Clean Air Act, as amended,
the Clean Water Act, as amended, the Comprehensive Environmental, Response,
Compensation, and Liability Act of 1980, as amended (“CERCLA”), the Federal
Water Pollution Control Act, as amended, the Resource Conservation and Recovery
Act of 1976, as amended (“RCRA”), the Safe
Drinking Water Act, as amended, the Toxic Substances Control Act, as amended,
the Hazardous & Solid Waste Amendments Act of 1984, as amended, the
Superfund Amendments and Reauthorization Act of 1986, as amended, the Hazardous
Materials Transportation Act, as amended, the Oil Pollution Act of 1990 (“OPA”), any state laws
implementing the foregoing federal laws, and any state laws pertaining to the
handling of oil and gas exploration and production wastes or the use,
maintenance, and closure of pits and impoundments, and all other environmental
conservation or protection laws in effect as of the date hereof which are
applicable to the Assets.  For purposes of this Agreement, the terms
“hazardous substance,” “release,” and “disposal” have the meanings specified in
the applicable Environmental Laws as in effect as of the date
hereof.

           

          (d)           Environmental Defect
Value. For purposes of this Agreement, the term “Environmental Defect
Value” shall mean, with respect to any Environmental Defect, the
estimated costs and expenses net to Seller’s interest in the affected portion of
the Assets to correct and/or remediate such Environmental Defect in the most
cost effective manner reasonably available, consistent with Environmental Laws,
taking into account that non-permanent remedies (such as, by way of example but
not by limitation or similarity, mechanisms to contain or stabilize hazardous
materials, including monitoring site conditions, natural attenuation, risk-based
corrective action, institutional controls, or other appropriate restrictions on
the use of property, caps, dikes, encapsulation, leachate collection systems,
etc.) may be the most cost effective manner reasonably available.

           

          Section
4.11                      Notice of Environmental
Defects.  Buyer shall provide Seller notice of all
Environmental Defects no later than 5:00 p.m. MST on the date which is seven (7)
days prior to the Closing Date. To be effective, such notice must (a) be in
writing, (b) be received by Seller prior to the expiration of the Examination
Period, (c) describe the Environmental Defect in reasonable detail, including
the written conclusion of Buyer that an Environmental Defect exists, which
conclusion shall 

           

          
            
              
              

            

            
              23

              
                

              

            

            
              
              

            

          

           

          be
reasonably substantiated by the factual data gathered in Buyer’s Environmental
Review, (d) identify the specific Assets affected by such Environmental Defect,
(e) set forth the procedures recommended to correct the Environmental Defect,
(f) set forth Buyer’s reasonable good faith estimate of the Environmental Defect
Value, including the basis for such estimate, and (g) comply with the
Environmental Defect Value provisions of 
Section 4.14. Any
matters that may otherwise constitute Environmental Defects, but of which Seller
has not been specifically notified by Buyer in accordance with the foregoing,
together with any environmental matter that does not constitute an Environmental
Defect, shall be deemed to have been waived by Buyer for all purposes and
constitute an Assumed Obligation. Upon receipt of notices of Environmental
Defects, the Parties shall meet and determine upon which of the Environmental
Defects, Environmental Defect Values, and methods of correction the Parties have
reached agreement. Upon the receipt of such effective notice from Buyer, Seller
shall have the option, but not the obligation, to attempt to correct such
Environmental Defect during a period expiring ninety (90) days after Closing. If
Seller should not elect to correct an Environmental Defect, and no aspect of
such defect is in dispute, the Purchase Price shall, subject to Section 4.14, be
adjusted for such defect by the amount of the Environmental Defect
Value.

           

          Section
4.12                      Remedies for Environmental
Defects.

           

          (a)           If,
as of the Closing Date, the Assets are affected by an uncured or otherwise
unresolved Environmental Defect noticed pursuant to the provisions of 
Section 4.11, the
affected portion of the Assets shall not be sold, transferred, or conveyed to
Buyer at Closing, and the Purchase Price shall, subject to the terms of 
Section 4.14, be
decreased by the Allocated Value of the portion of the Assets so
affected.  Thereafter, Buyer and Seller shall act reasonably and in
good faith either (i) to agree (y) as to the manner of cure for such
Environmental Defect or (z) the value of such Environmental Defect and adjust
the Final Settlement Statement in the amount thereof net of any Purchase Price
adjustment made at Closing, in which event the affected portion of the Assets
shall be conveyed to Buyer; provided that if option (y) is agreed to, no
assignment of the affected portion of the Assets shall be made as between Seller
and Buyer until such agreed cure is accomplished to Buyer’s reasonable
satisfaction whereupon the Allocated Value previously deducted from the Purchase
Price shall be paid to Seller, or (ii) with respect to any Environmental Defect
as to which the Parties are unable to agree within 30 days of Closing as to the
validity of the Environmental Defect, the Environmental Defect Value, or the
manner of correction, submit such matter to be determined by an Independent
Expert pursuant to Section
4.13.

           

          
            
              
              

            

            
              24

              
                

              

            

            
              
              

            

          

           

          (b)           With
respect to any Asset which is not sold, transferred, or conveyed to Buyer at the
Closing pursuant to the terms of 
Section 4.12(a),
after the Closing and at such time as any Environmental Defect Value or the
manner of correction for an Environmental Defect is determined and, in either
event, the amount thereof is determined to be less than the Allocated Value for
the affected portion of the Assets, Seller shall have the right (i) in the
case of an Environmental Defect Value determination, to have the Purchase Price
reduced by only the Environmental Defect Value as so determined or (ii) in
the case of the cure determination, to elect to cure the Environmental Defect to
Buyer’s reasonable satisfaction. The consequence of (i) shall be that Buyer
will pay to Seller an amount equal to the Allocated Value for the affected
Assets minus the Environmental Defect Value and the affected portion of the
Assets previously retained by Seller shall be conveyed to Buyer.  The
consequence of (ii) shall be that upon achieving Buyer’s written
acknowledgement that the Environmental Defect has been cured to its reasonable
satisfaction, the Allocated Value for such previously retained Asset shall be
paid to Seller and the affected portion of the Assets shall be conveyed to
Buyer.  If no Environmental Defect is determined to exist, Buyer shall
pay the Allocated Value attributable to the affected portion of the Assets to
Seller, and Seller shall convey the previously retained portion of the Assets to
Buyer.  If the Environmental Defect Value or the cost to cure an
Environmental Defect is determined to be greater than the Allocated Value of the
affected portion of the Assets, Seller shall retain the affected portion of the
Assets, and the Purchase Price shall be reduced by the Allocated Value
attributable to such portion of the Assets.

           

          Section
4.13                      Independent
Experts.

           

          (a)           Any
disputes regarding Title Defects, Title Benefits, Environmental Defects, Title
Defect Value, Title Benefit Value, Environmental Defect Value, appropriate cure
of any Title Defects or correction of any Environmental Defects, and the
calculation of the Statement or the Final Settlement Statement, or revisions
thereto, may, subject to the provisions of 
Section 4.04, 
Section 4.12, and

Section 4.14, be
submitted by a Party, with written notice to the other Party, to an independent
expert (the “Independent Expert”),
who shall serve as the sole and exclusive arbitrator of any such dispute. The
Independent Expert shall be selected by the Parties (acting reasonably and in
good faith) within fifteen (15) days following the effective date of said
notice. The Independent Expert shall be a person who is independent, impartial,
and knowledgeable in the subject matter and substantive laws
involved.  For example, but not by way of limitation, in the case of a
dispute concerning an alleged Environmental Defect, Environmental Defect Value,
or cure of the same, the Independent Expert shall have expertise in both the
applicable Environmental Laws and environmental science relating to the oil and
gas industry.

          (b)           The
Parties shall determine, acting in good faith, the procedures to be followed to
facilitate the decision of the Independent Expert. Such procedures shall include
the following scenario:

           

          (i)           If
the dispute involves the method or adequacy of cure or correction of a Title
Defect or Environmental Defect, the Independent Expert shall provide in writing
the particulars necessary to cure or correct or to remedy any such Title Defect
or Environmental Defect, and shall provide Seller sixty (60) days (or such
additional time as reasonable and necessary under the circumstances, but not to
exceed 90 days unless specifically agreed to in writing by Seller and Buyer) to
effect such cure or correction; and

           

          (ii)           In
the event of circumstances described in clause (i) above, Seller at its option
may at any time during the sixty (60) day cure period pursuant to clause (i) (as
such period may be extended pursuant to such clause) decline to cure or correct
the applicable defect.

           

          (c)           If
the Parties fail to select an Independent Expert within the 15-day period
referred to in 
Section 4.13(a)
above, within three (3) days thereafter, each of Buyer and Seller shall choose
an Independent Expert meeting the qualifications set forth above, and such
experts shall promptly choose a third Independent Expert (meeting the
qualifications provided for herein) who alone shall resolve the disputes between
the Parties. Each Party shall bear its own costs and expenses incurred in
connection with any such proceeding, and one-half (1/2) of the costs and
expenses of the Independent Expert.

           

          
            
              
              

            

            
              26

              
                

              

            

            
              
              

            

          

           

          (d)           Disputes
to be resolved by an Independent Expert shall be resolved in accordance with
mutually agreed procedures and rules and failing such agreement, in accordance
with the rules and procedures for non-administered arbitration set forth in the
commercial arbitration rules of the American Arbitration
Association.  The Independent Expert shall be instructed by the
Parties to resolve such dispute as soon as reasonably practicable in light of
the circumstances using the terms and provisions of this Agreement with respect
to title and environmental matters. The decision and award of the Independent
Expert shall be binding upon the Parties and shall be final and nonappealable to
the maximum extent permitted by Laws or Environmental Laws, as applicable, and
judgment thereon may be entered in a court of competent jurisdiction and
enforced by any Party as a final judgment of such court.

           

          (e)           All
proceedings under this 
Section 4.13
shall be conducted at a mutually agreed location, or if Buyer and Seller acting
reasonably do not mutually agree upon a location for such proceeding, the
proceeding shall be conducted in Denver, Colorado.

           

          Section
4.14                      Limitation of Remedies For
Title Benefits, Title Defects and Environmental
Defects.  Notwithstanding anything to the contrary contained in
this Agreement,

           

          (a)           if
the Title Defect Value for a given Title Defect, or the Title Benefit Value of a
given Title Benefit, in each case as determined pursuant to this 
Article 4 does
not exceed Ten Thousand Dollars ($10,000), or if the Environmental Defect Value
for a given Environmental Defect, as determined pursuant to this 
Article 4 does
not exceed Ten Thousand Dollars ($10,000), such Title Defect, Title Benefit, or
Environmental Defect shall not qualify for either a Purchase Price adjustment,
cure, or correction of such defect, nor shall it be included in the calculation
of subparagraphs (b), (c), (d), or (e) below;

           

          (b)           if
the aggregate net value of all Title Defects and Title Benefits does not exceed
Five Hundred Thousand Dollars ($500,000) (prior to any adjustments thereto),
then no adjustment of the Purchase Price shall be made therefor;

           

          (c)           if
the aggregate net value of all Title Defects and Title Benefits exceeds Five
Hundred Thousand Dollars ($500,000) (prior to any adjustments thereto), then the
Purchase Price shall be adjusted by the entire amount of such aggregate net
value, it being understood that this amount is a threshold and not a
deductible;

          (d)           if
the aggregate value of all Environmental Defects does not exceed Five Hundred
Thousand Dollars ($500,000) (prior to any adjustments thereto), then no
adjustment of the Purchase Price shall be made therefor; and

           

          (e)           if
the aggregate value of all Environmental Defects exceeds Five Hundred Thousand
Dollars ($500,000) (prior to any adjustments thereto), then the Purchase Price
shall be adjusted by the entire amount of such aggregate value, it being
understood that this amount is a threshold and not a deductible.

           

          All Title
Defects and Environmental Defects asserted by Buyer pursuant to this 
Article 4 after
being resolved in accordance with this 
Article 4 shall
thereafter constitute Permitted Encumbrances and Assumed Obligations, whether or
not an adjustment to the Purchase Price is made with respect thereto in
accordance with this 
Article
4.

Closing.  Other than in connection with normal and customary prudent
operations, Seller has not removed any personal property, equipment, or fixtures
from the Wells, unless it has been replaced with personal property, equipment,
or fixtures of similar grade and utility.  Unless removed, repaired,
or replaced (a) with personal property, equipment, and fixtures of similar grade
and utility or (b) in connection with normal and customary prudent operations,

division orders or spot sales agreements terminable on no more than 30 days
notice) and no person has any call upon, option to purchase, or similar rights

all material respects to the extent relating to any period of ownership of the

create any preferential right to purchase, right of first opportunity, or other
transfer restriction or requirement with respect to the Assets except in
connection with the renewal or extension of Assets after the Effective Time if

(ix) not elect to become a nonconsenting party in any operation proposed by

          (b)           Buyer
acknowledges that Seller owns undivided interests in some or all of the Assets,
and Buyer agrees that the acts or omissions of the other working interests
owners shall not constitute a violation of the provisions of this 
Article 7, nor
shall any action required by a vote of working interest owners constitute such a
violation so long as Seller has voted its interests in a manner that complies
with the provisions of this 
Article 7. Seller
will, without penalty for the failure to do so except to the extent that the
failure to give Buyer such notice has a Material Adverse Effect, notify Buyer of
the occurrence of such event to the extent of Seller’s knowledge.

           

          (c)           Promptly
upon its discovery or identification of same, but in any event prior to Closing,
Seller shall provide Buyer written notice of any matter Seller identifies that
has a material adverse effect on or that constitutes a Breach of Seller’s
representations or warranties under this Agreement.

          Section
7.02                      Buyer’s
Qualification.  At Closing, Buyer (or Buyer’s designee as
contract operator) shall be qualified and shall meet all requirements, including
bonding requirements, to be designated operator of that portion of the Assets
for which Seller serves as operator.

           

          Section
7.03                      Operation of the Assets
after the Closing.

           

          (a)           Seller
shall not be obligated to continue operating any of the Assets following the
Closing, and, subject to Seller’s retention of the Retained Liabilities, Buyer
hereby assumes full responsibility for operating (or causing the operation of)
all Assets following the Closing for which Seller is the operator prior to the
Closing Date. Seller shall make its employees and contractors available to Buyer
prior to the Closing as may be reasonably necessary to assist in the transition
if Buyer becomes the operator. Seller does not warrant or guarantee that Buyer
will become the operator of the Assets or any portion thereof, as such matter
will be controlled by the applicable joint operating agreement(s) and other
applicable agreement(s). Without implying any obligation on Seller’s part to
continue operating any Assets after the Closing, if Seller elects, at its sole
option, to continue to operate any Assets following the Closing at the request
of Buyer, or by any third party working interest owner due to constraints of
applicable joint operating agreement(s) and other applicable agreement(s),
failure of a successor operator to take over operations, or for other reasonable
cause, such continued operation by Seller shall be for the account of Buyer, and
at the sole risk, cost, and expense of Buyer. Buyer agrees to release and
defend, indemnify and hold Seller and its Representatives harmless from Claims,
including any Claims of Buyer or its affiliates or successors and assigns
relating in any manner directly or indirectly to the operation of the Assets
after Closing (INCLUDING THOSE
CLAIMS RESULTING FROM THE SOLE, JOINT OR CONCURRENT NEGLIGENCE (BUT NOT GROSS
NEGLIGENCE OR WILLFUL MISCONDUCT), STRICT LIABILITY OR OTHER LEGAL FAULT OF
SELLER OR ANY OF SELLER’S REPRESENTATIVES).

           

          (b)           Any
conduct of operations of the Assets by Seller on behalf of Buyer after Closing
shall be conducted pursuant to a transition services agreement or other contract
operating agreement to be separately negotiated 

           

          
            
              
              

            

            
              38

              
                

              

            

            
              
              

            

          

           

          by and
between Buyer and Seller, which agreement shall provide for reimbursement to
Seller for any monies expended on Buyer’s behalf and shall further compensate
Seller for all general and administrative overhead incurred by Seller in
connection with the conduct of operations undertaken pursuant to such
agreement.  This agreement shall provide the services that Seller
shall provide and such may be of an operational nature or may be limited to
accounting, distribution, and/or reporting services, all as the Parties shall
agree in such subsequent agreement.  In the event Seller transfers
operations to Buyer or its designee between the first and last day of a calendar
month, Seller shall be paid such amount of the general and administrative
overhead prorated over the number of days in which Seller conducted operations
for such month.

           

          Section
7.04                      Post Closing Accounting by
Seller.  In the event Seller agrees to operate the Assets after
Closing, and unless otherwise agreed to by the Parties, Seller shall perform the
following accounting tasks subject to the limitations provide for
herein:

           

          (a)           Seller
will continue to pay royalties and severance, production, and similar Taxes for
sales through the production month following the month in which Closing occurs
(“Post-Closing
Production
Month”). If any revenue is received by Seller for later months, it will
be credited to Buyer in the Final Settlement Statement; provided however, Seller
shall not be obligated to and will not pay any royalties and severance,
production, and similar Taxes, if applicable, with respect to Hydrocarbons
produced after the Post-Closing Production Month.

           

          (b)           Seller
will continue to pay or bill joint interest owners for expenses through the
Post-Closing Production Month. All later expenses will be either accumulated or
charged to Buyer in the Final Settlement Statement, or the invoices will be
returned to the vendor for rebilling to Buyer.  Seller will continue
to pay to the operator of any Assets not operated by Seller the joint billings
for the billing month after the month in which Closing occurs.  All
subsequent bills will either be returned to the applicable operator for
rebilling to Buyer or forwarded to Buyer for payment, or if already paid by
Seller, will be charged against Buyer in the Final Settlement
Statement.  Seller will continue to prepare all regulatory and other
monthly production reports through the Post-Closing Production Month. Copies of
such reports attributable to the period after the Effective Time will be
provided to Buyer, along with the final ending inventory balance.

           

          
            
              
              

            

            
              39

              
                

              

            

            
              
              

            

          

           

          (c)           Seller
will continue to pay all shut-in royalties, minimum royalties, delay rentals,
and other lease payment obligations through the Post-Closing Production
Month.

           

          (d)           Seller
shall market and nominate all Hydrocarbons in the same manner as Seller has been
marketing and nominating Hydrocarbons.

           

          Section
7.05                      Limitations on Liability of
Operator.  Notwithstanding anything herein to the contrary, in
the event Seller or an affiliate of Seller should assume any accounting
functions on behalf of Buyer from and after Closing, Seller shall have no
liability to Buyer for, and Buyer hereby agrees to release and defend, indemnify
and hold Seller and Seller’s Representatives harmless from, the incorrect
payment of expenses, Taxes, billings, delay rentals, royalties, minimum
royalties, payments required by any of the Leases, shut-in royalties, or similar
payments, or for any failure to pay any such payments through mistake or
oversight (INCLUDING THOSE
RESULTING FROM THE SOLE, JOINT OR CONCURRENT NEGLIGENCE (BUT NOT GROSS
NEGLIGENCE OR WILLFUL MISCONDUCT), STRICT LIABILITY, OR OTHER LEGAL FAULT OF
SELLER OR ANY OF SELLER’S REPRESENTATIVES) from and after the
Effective Time, except to the extent of any amounts included in the upward
Purchase Price Allocations and Adjustment made pursuant to 
Section
10.02.  In no event shall Buyer’s remedy for Breach of
obligations by Seller (or any of its Representatives) under this 
Article 7 exceed
the Allocated Value of the portion of the Subject Interests affected by such
Breach.

           

          Section
7.06                      Public
Announcements. Prior to the Closing,
neither Party shall make any press release or other public announcement
regarding the existence of this Agreement, the contents hereof or the
transactions contemplated hereby without the express written consent of the
other Party; provided, however, the foregoing shall not restrict disclosures by
Buyer or Seller which are required by applicable securities or other Laws or the
applicable rules of any stock exchange having jurisdiction over the disclosing
Party or its Affiliates.  Following Closing, the Parties shall issue a
Press Release in form and substance to be agreed upon by the Parties prior to
the Closing, but again, the foregoing shall not restrict disclosures by Buyer or
Seller which are required by applicable securities or other Laws or the
applicable rules of any stock exchange having jurisdiction over the disclosing
Party or its Affiliates.

          Adjustments.
Each Party shall provide the other such data and information as may be
reasonably requested to permit Seller to prepare the Final Settlement Statement
or to permit Buyer to perform or cause to be performed an audit of the Final
Settlement Statement. The Final Settlement Statement shall become final and
binding upon the parties on the thirtieth (30th) day following receipt thereof
by Buyer (the “Final
Settlement Date”) unless Buyer gives written notice of its disagreement
(a “Notice of Disagreement”) to
Seller prior to such date. Any Notice of Disagreement shall specify in
reasonable detail the dollar amount and the nature and basis of any disagreement
so asserted. If a Notice of Disagreement is received by Seller in a timely
manner, then the Parties shall resolve the dispute evidenced by the Notice of
Disagreement by mutual agreement, or otherwise in accordance with

pay, or if paid by Buyer, promptly reimburse Buyer in immediately available
funds for and indemnify, defend, and hold Buyer harmless from and against the
same; and

           

          (ii)           All
costs and expenses relating to the Assets for which Buyer is responsible (being
those incurred on or after the Effective Time) shall be the sole obligation of
Buyer and Buyer shall promptly pay, or if paid by Seller, promptly reimburse

Buyer.  The Parties will reasonably cooperate to eliminate or reduce
the assessment of sales or use taxes to the extent permitted by applicable
Law.  If Seller (not Buyer) is required by applicable Law to appeal or
protest the assessment of sales or use taxes, Seller shall protest the
assessment of those taxes if Buyer requests Seller in writing to make such
appeal or protest, and, in such event, Buyer will reimburse Seller all
out-of-pocket expenses authorized by Buyer and incurred by Seller in connection

indemnities of the indemnifying Party in this Agreement do not cover or include
any amounts that the indemnified party may legally recoup from other third party
owners under applicable joint operating agreements or other agreements, and for
which the indemnified party is reimbursed by any third party. The indemnifying
Party will pay all costs incurred by the indemnified party in obtaining
reimbursement from third parties. There will be no upward or downward adjustment
in the Purchase Price as a result of any matter for which Buyer or Seller is
indemnified under this Agreement.

Breach of, or failure to perform or satisfy any of the covenants and obligations
of Buyer hereunder.

           

          Section

Representatives harmless from and against any and all Claims caused by,
resulting from, or incidental to the Retained Obligations, and any Claims caused
by, or resulting from, or attributable to (a) the Breach of any representation
or warranty of Seller set forth in 
Section 5.04 to

          against
the indemnified Party relating to any Claim for which the indemnifying Party has
agreed to release and indemnify and hold the indemnified Party harmless under
this Agreement; provided, however, that the failure to give such notice shall
not relieve the indemnifying Party from its obligations unless such failure to
give notice actually prejudices the indemnifying Party and so long as the notice
is given within the period set forth in Section
12.10.  The indemnified Party shall have the right to
participate with the indemnifying Party in the defense of any such Claim at its
own expense.

           

          Section

representations, warranties, covenants, and agreements of the Parties set forth
herein shall not survive the Closing and the consummation of the transactions
contemplated hereby, and Buyer and Seller each covenant not to sue the other
based upon any alleged Breach of any such representations or warranties that do
not survive the Closing. The indemnity of Seller as provided in 
Section 12.08
shall survive only for a period of twenty-four (24) months after the Closing.
Notwithstanding anything to the contrary, Buyer shall not be entitled to make,
and hereby waives the right to assert, any claim for indemnity pursuant to the
provisions of this 
Article 12
against Seller unless Buyer seeks indemnification for such claim by a written
notice received by Seller on or before the date that is twenty-four (24) months
after the Closing Date (the “Expiration Date”).
Anything in this Agreement to the contrary notwithstanding, after the Expiration
Date, all of the Retained Liabilities and all of Seller’s other liabilities and
obligations with respect to the Assets (and all Claims with respect thereto)
shall be deemed and constitute Assumed Obligations except to the extent of any
Claims of which Buyer notifies Seller on or before the Expiration Date in
accordance with this Agreement.

Article 12 and
those provided in 
Article 2,

be the sole and exclusive remedy of each of the Parties indemnified hereunder
with respect to the representations, warranties, covenants, and agreements of
the Parties set forth in this Agreement and the other documents executed and
delivered hereunder; provided, however, that the terms of this 
Section 12.11

securities fraud (where one of the elements of the cause of action is scienter
or knowledge), willful misconduct, or gross negligence.

entitled to the use and benefit of all defenses (legal and equitable) and

statutory limitations now or hereafter in effect affecting the validity or
enforceability of the indemnities provided for in this Agreement, such
indemnities shall be deemed amended in order to comply with such limitations.
This provision concerning statutory limitations shall not apply to indemnities
for all liabilities of the indemnifying Party which are covered by such Party’s
insurance.

          Section
13.02                                NORM.  BUYER ACKNOWLEDGES THAT IT HAS BEEN
INFORMED THAT OIL AND GAS PRODUCING FORMATIONS CAN CONTAIN NATURALLY OCCURRING
RADIOACTIVE MATERIAL (“NORM”). SCALE FORMATION OR SLUDGE
DEPOSITS CAN CONCENTRATE LOW LEVELS OF NORM ON EQUIPMENT AND OTHER ASSETS. THE
ASSETS SUBJECT TO THIS AGREEMENT MAY HAVE LEVELS OF NORM ABOVE BACKGROUND
LEVELS, AND A HEALTH HAZARD MAY EXIST IN CONNECTION WITH THE ASSETS BY REASON
THEREOF. THEREFORE, BUYER MAY NEED TO AND SHALL FOLLOW SAFETY PROCEDURES WHEN
HANDLING THE EQUIPMENT AND OTHER ASSETS.

           

          Section
13.03                                Casualty Loss;
Condemnation.

           

          (a)           Except
as otherwise provided in this Agreement, Buyer shall assume all risk of loss
with respect to, and any change in the condition of, the Assets from and after
the Effective Time, including with respect to the depletion of Hydrocarbons, the
watering-out of any well, the collapse of casing, sand infiltration of wells,
and the depreciation of personal property.

           

          (b)           Prior to the Closing, there
shall not have been a material adverse change in the Assets taken as a whole
caused by an event of casualty (a “Casualty”), including but not limited to,
volcanic eruptions, acts of God, fire, explosion, earthquake, wind storm, flood,
drought, condemnation, the exercise of any right of eminent domain,
confiscation, or seizure, but excepting depletion due to normal production and
depreciation or failure of equipment or casing.

           

          (c)           If,
prior to the Closing, a Casualty occurs (or Casualties occur) which results in a
reduction in the value of the Assets in excess of fifteen percent (15%) of the
Purchase Price (“Casualty Loss”),
Buyer or Seller may

          elect to
terminate this Agreement.  If this Agreement is not so terminated,
then this Agreement shall remain in full force and effect notwithstanding any
such Casualty Loss, and, at Buyer’s sole option, (i) Seller shall retain such
Asset subject to such Casualty and such Asset shall be the subject of an
adjustment to the Purchase Price in the same manner set forth in 
Section 4.03
hereof, or (ii) at the Closing, Seller shall pay to Buyer all sums paid to
Seller by reason of such Casualty Loss, provided, however, that the Purchase
Price shall not be adjusted by reason of such payment, and Seller shall assign,
transfer, and set over unto Buyer all of the right, title, and interest of
Seller in and to such Asset and any unpaid awards or other payments arising out
of such Casualty Loss.

           

          (d)           For
purpose of determining the value of a Casualty Loss, the Parties shall use the
same methodology as applied in determining the value of a Title Defect as set
forth in 
Section
4.03(a).

shall be entitled to any reimbursement for any such expenses from the other
Party.

          Section
14.11                                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
and the Parties shall negotiate in good faith to modify this Agreement so as to
effect their original intent as closely as possible in an acceptable manner to
the end that the transactions contemplated hereby are fulfilled to the extent
possible.

           

          Section
14.12                                Interpretation.  This
Agreement shall be deemed and considered for all purposes to have been jointly
prepared by the Parties, and shall not be construed against any one Party (nor
shall any inference or presumption be made) on the basis of who drafted this
Agreement or any particular provision hereof, who supplied the form of
Agreement, or any other event of the negotiation, drafting, or execution of this
Agreement. Each Party agrees that this Agreement has been purposefully drawn and
correctly reflects its understanding of the transaction that it contemplates. In
construing this Agreement, the following principles will apply:

           

          (a)           A
defined term has its defined meaning throughout this Agreement and each Exhibit
and Schedule to this Agreement, regardless of whether it appears before or after
the place where it is defined.

           

          (b)           If
there is any conflict or inconsistency between the provisions of the main body
of this Agreement and the provisions of any Exhibit or Schedule hereto, the
provisions of this Agreement shall take precedence. If there is any conflict
between the provisions of any Assignment or other transaction
documents attached to this Agreement as an Exhibit and the provisions of any
Assignment and other transaction documents actually executed by the parties, the
provisions of the executed Assignment and other executed transaction documents
shall take precedence.

           

          
            
              
              

            

            
              64

              
                

              

            

            
              
              

            

          

           

          (c)           Schedules
and Exhibits referred to herein are hereby incorporated and made a part of this
Agreement for all purposes by such reference.

           

          (d)           The
omission of certain provisions of this Agreement from the Assignment does not constitute a
conflict or inconsistency between this Agreement and the Assignment, and will
not effect a merger of the omitted provisions. To the fullest extent permitted
by Laws, all provisions of this Agreement are hereby deemed incorporated into
the Assignment by reference.

           

          (e)           The
words “includes” and “including” and their
derivatives means “includes, but not limited to” or “including, but not limited
to,” and corresponding derivative meanings.

           

          (f)           The
Article, Section, Exhibit, and Schedules references in this Agreement refer to
the Articles, Sections, Exhibits, and Schedules of this Agreement. The headings
and titles in this Agreement are for convenience only and shall have no
significance in interpreting or otherwise affect the meaning of this
Agreement.

           

          (g)           The
terms “knowledge” or “knowingly,” whether
or not capitalized, shall mean the actual knowledge of a Party’s employees who,
as of Closing are in a supervisory capacity responsible for the ownership and
operation of the Assets and any material facts relating thereto, after a due and
diligent inquiry.

           

          (h)           The
adjective, “material”, whether or
not capitalized, shall mean a situation, circumstance, consequence, or concept
whose relevance to the transactions contemplated by this Agreement as a whole is
of significance, and would not be considered a small or insignificant deviation
from the terms of this Agreement.

           

          (i)           The
term “Material Adverse
Effect” shall mean any defect, condition, change, or effect (other than
with respect to which an adjustment to the Purchase Price has been made) that
when taken together with all other such defects, conditions, changes, and
effects significantly diminishes the value, use, operations, or development of
the Assets, taken as a whole. Notwithstanding the foregoing, the following shall
not be considered in determining whether a Material Adverse Effect has
occurred:

           

          
            
              
              

            

            
              65

              
                

              

            

            
              
              

            

          

           

          (i)           Fluctuations
in commodity prices;

           

          (ii)           Changes
in Laws or Environmental Laws; or

           

          (iii)           Changes
in the oil and gas industry that do not have a disproportionate impact on the
ownership and operation of the Assets.

           

          (j)           “Breach” shall mean
any breach of, or any falsity or inaccuracy in, any representation or warranty
or any breach of, or failure to perform or comply with, any covenant or
obligation, in or of this Agreement or any other contract, agreement, or
instrument contemplated by this Agreement or any event which with the passing of
time or the giving or notice, of both, would constitute such a breach,
inaccuracy, or failure; provided that to constitute a Breach, such breach,
inaccuracy, or failure must be material to the subject matter regarding which
the Breach is asserted.

           

          (k)           “Tax” means all taxes
and any other assessments, duties, fees, levies, or other charges imposed by a
Governmental Authority based on or measured by the value of the Assets, the
production of Hydrocarbons, the receipt of proceeds with respect to such Assets
or Hydrocarbons, or otherwise related in any manner or attributable to the
Assets or the production of Hydrocarbons including any production tax, windfall
profits tax, severance tax, personal property tax, real property tax, or ad
valorem tax, together with any interest, fine, or penalty thereon, or in
addition thereto.

           

          (l)           The
plural shall be deemed to include the singular, and vice versa.

           

          Section
14.13                                Time of the
Essence.  Time shall be of the essence with respect to all time
periods and notice periods set forth in this Agreement.

           

          Section
14.14                                Counterpart
Execution.  This Agreement may be executed in any number of
counterparts, and each counterpart hereof shall be effective as to each Party
that executes the same whether or not all of such Parties execute the same
counterpart. If counterparts of this Agreement are executed, the signature pages
from various counterparts may be combined into one composite instrument for all
purposes. All counterparts together shall constitute only one Agreement, but
each

          counterpart
shall be considered an original.  In the event that this Agreement is
delivered by facsimile transmission or by e-mail delivery of a “.pdf” format
date file, such signature shall create a valid and binding obligation of the
Party executing (or on whose behalf such signature is executed) with the same
force and effect as if such facsimile or “.pdf” signature page were an original
thereof.  To facilitate the execution and recording of the conveyance
of the Assets from Seller to Buyer, the Parties agree that they may execute
multiple assignments substantially in the form attached as Exhibit E which
contain only that portion of the Assets that are located in a particular county,
and all such assignments shall constitute a single conveyance of the Assets from
Seller to Buyer.

           

          Section
14.15. Audit
Rights.   Seller agrees to make available to Buyer prior
to and for a period of twelve (12) months following the Closing any and all
existing information and documents in the possession of Seller that Buyer may
reasonably require to comply with Buyer’s tax and financial reporting
requirements and audits.  Without limiting the generality of the
foregoing, Seller will use its commercially reasonable efforts after execution
of this Agreement and for twelve (12) months following Closing to cooperate with
the independent auditors chosen and paid for by Buyer (“Buyer’s Auditor”) in
connection with their audit of any annual revenue and expense statements of the
Assets that Buyer or any of its affiliates requires to comply with their tax and
financial reporting requirements, and their review of any interim quarterly
revenue and expense statements of the Assets that Buyer requires to comply with
such reporting requirements.  Seller’s cooperation will include (i)
such reasonable access to Seller’s employees who were responsible for preparing
the revenue and expense statements and work papers and other supporting
documents used in the preparation of such financial statements as may be
required by Buyer’s Auditor to perform an audit in accordance with generally
accepted auditing standards, and (ii) delivery of one or more customary
representation letters (in substantially the form previously approved by Seller
and Buyer) from Seller to Buyer’s Auditor that are requested by Buyer to allow
such auditors to complete an audit (or review of any interim quarterly
financials), and to issue an opinion that in Buyer’s experience is acceptable
with respect to an audit or review of those revenue and expense statements
required pursuant to this Section.  Buyer will reimburse Seller,
within three (3) business days after demand therefor, for any reasonable
out-of-pocket and overhead costs with respect to any costs incurred by Seller in
complying with the provisions of this Section.  In the event that
Buyer’s Auditors determine that any of the Assets are not auditable due to
insufficient financial records, or for any reason determined by Buyer’s
Auditors, then Buyer may exclude the unauditable Assets from this sale and the
Purchase Price will be reduced by the Allocated Value of said
Assets.

of the date first set forth above.
