Agreement;

including changes that would raise the minimum landowner royalty;
(j)    defects that affect only which Person has the right to receive Burden

Net Revenue Interest with respect to any Title Well to an amount less than the
Net Revenue Interest set forth in Exhibit A-1 for such Title Well; or

been subordinated to the lessee’s interest and for which a reasonably prudent
lessee would not customarily seek a subordination of such Encumbrance to the oil

complaint of foreclosure has been duly filed or any similar action taken by the
mortgagee or trustee thereunder;

Tax assessment, Tax payment or similar records or the absence of such activities
or records;

covered by the Leases or Units not being surrendered of record, unless Buyer
provides affirmative evidence that such prior oil and gas lease is still in
effect and would result in another Person’s actual and superior claim of title
to the relevant Lease or Title Well;
(o)    all defects or irregularities resulting from the failure to record
releases, Encumbrances or production payments that have expired on their own
terms; and

(o)    all drilling rigs and all other properties and assets specifically

(r)    any assets or properties otherwise expressly identified as Excluded
Assets under this Agreement.

2.3    Revenues and Expenses. For purposes of determining the amount of the
adjustment to the Purchase Price provided for in Section 3.3, the principles set
forth in this Section 2.3 shall apply except as expressly provided otherwise in
this Agreement. Subject to the preceding sentence: (i) Seller shall remain
entitled to all of the rights of ownership (including the right to all
production, proceeds of production and other proceeds, if any) and shall remain
responsible for all Operating Expenses, in each case attributable to the Assets
for the period of time prior to the Effective Time, (ii) and subject to the
occurrence of the Closing, Buyer shall be entitled to all of the rights of
ownership (including the right to all production, proceeds of production and
other proceeds) attributable to the Assets for the period of time from and after
the Effective Time, and shall be responsible for all Operating Expenses
attributable to the Assets for the period of time from and after the Effective
Time. Such amounts that are received or paid prior to Closing shall be accounted
for in the Closing Settlement Statement or Final Settlement Statement, as
applicable. Such amounts that are received or paid after Closing but prior to
the date of the Final Settlement Statement shall be accounted for in the Final
Settlement Statement. For the avoidance of doubt, the date an item or work is
ordered is not the date of a transaction for settlement purposes in the Closing
Settlement Statement or Final Settlement Statement, as applicable, but rather
the date on which the item ordered is delivered to the job site, or the date on
which the work ordered is performed, is the relevant date (i.e., on an accrual
basis). “Earned” and “incurred”, as used in this Agreement, shall be interpreted
in accordance with GAAP and COPAS standards, as applied by Seller in the
ordinary course of business consistent with past practice, subject to the other
provisions of this Section 2.3. For purposes of allocating production (and
accounts receivable with respect thereto), under this Section 2.3, (a) liquid
Hydrocarbons shall be deemed to be “from or attributable to” the Wells when they
pass through the pipeline connecting into the storage facilities into which they
are transported from the lands covered by the applicable Well, or if there are
no storage facilities, when they pass through the LACT meter or similar meter at
the entry point into the pipelines through which they are transported from such
lands and (b) gaseous Hydrocarbons shall be deemed to be “from or attributable
to” the Wells when they pass through the delivery point sales meters or similar
meters at the entry point into the pipelines through which they are transported
from such lands. Seller shall utilize reasonable interpolative

xxxvi
US-DOCS\112434093.5

--------------------------------------------------------------------------------

procedures to arrive at an allocation of production when exact meter readings
(including gas production meters or sales meters) or gauging and strapping data
is not available.

2.4    Assigned Contracts; Cure Costs.
(a)    At the Closing, Buyer shall pay, pursuant to Section 365 of the
Bankruptcy Code, Section 1123(b)(2) of the Bankruptcy Code, and the Sale Order,
any and all costs or expenses that are required to be paid under sections
365(b)(1)(A), 365(b)(1)(B), and 1123(b)(2) of the Bankruptcy Code, as
applicable, to cure any defaults in connection with the assumption and
assignment of the Assigned Contracts (such costs or expenses required to be paid
by Buyer, the “Cure Costs”). For the avoidance of doubt, (i) Buyer shall pay all
Cure Costs in cash at such time as is provided in the preceding sentence, and
(ii) neither Buyer nor any Buyer Affiliates shall be required to make any
payment of Cure Costs for, and neither Buyer nor any Buyer Affiliates shall
assume or have any obligation for any Liabilities with respect to, any Excluded
Contract.
(b)    Schedule 2.4 sets forth each Applicable Contract and Seller’s good faith
estimate of the amount of the Cure Costs payable in respect of each such
Applicable Contract (and if no Cure Cost is estimated to be payable in respect
of any Applicable Contract, the amount of such Cure Cost designated for such
Applicable Contract shall be “$0.00”). Seller shall use its reasonable best
efforts to provide, and to cause the Seller Representatives to provide,
financial and other pertinent information regarding the Applicable Contracts, as
is reasonably requested by Buyer, including using Seller’s reasonable best
efforts to furnish Buyer’s financing sources with such financial and other
pertinent information regarding such Applicable Contracts as may be reasonably
requested. Seller shall amend or supplement Schedule 2.4 from time to time
promptly, and shall provide Buyer written notice thereof, upon its determination
that any Seller Party is party to an Applicable Contract that is not then set
forth on Schedule 2.4.
(c)    Within ten Business Days after the Execution Date, and subject to Buyer’s
rights under Section 2.4(e) below to subsequently amend such designations, Buyer
will deliver to Seller schedules of the Applicable Contracts to be assumed by
Seller and assigned to Buyer (as Assigned Contracts) at the Closing. Seller
shall commence appropriate proceedings before the Bankruptcy Court and otherwise
take all reasonably necessary actions in order to determine Cure Costs with
respect to any Assigned Contracts including providing sufficient notice in
accordance with the Bidding Procedures Order to all counterparties to the
Assigned Contracts of their assumption or rejection and, with respect to the
Assigned Contracts to be assumed, providing a schedule of Cure Costs. Any
Applicable Contracts that are not set forth on such list of Applicable Contracts
to be assumed shall be Excluded Contracts and deemed rejected, and shall be an
Excluded Asset for all purposes hereof.
(d)    Buyer acknowledges that, prior to the Execution Date, Seller delivered
written notices in a form reasonably acceptable to Buyer (the “Initial
Applicable Contract Notices”) of the potential assignments of the Applicable
Contracts then known to Seller and the proposed Cure Costs for each such
Applicable Contract (consistent with Seller’s good faith estimates of such Cure
Costs at the times such Initial Applicable Contract Notices were delivered) to
all non-debtor parties to such Applicable Contracts, which notice provided
notice to each non-debtor party to such Applicable Contract of (i) the proposed
Cure Cost for such Applicable Contract and (ii) an objection

xxxvii
US-DOCS\112434093.5

--------------------------------------------------------------------------------

deadline for such non-debtor party to object to the proposed Cure Cost. To the
extent Schedule 2.4 is supplemented from time to time to include additional
Applicable Contracts in accordance with Section 2.4(b) above, Seller shall, as
promptly as is practicable, deliver written notice (each, a “Supplemental
Applicable Contract Notice” and, together with the Initial Applicable Contract
Notice, the “Contract Notices”) to the counterparties to such Applicable
Contracts of the potential assignment of such Applicable Contracts and the
proposed Cure Costs for such Applicable Contracts (consistent with Seller’s good
faith estimates set forth in Schedule 2.4), in substantially the same form as
the Initial Applicable Contract Notice. To the extent that any objections are
received from such non-debtor parties in response to such Contract Notices,
Seller shall take all reasonably necessary actions (excluding providing any
payment of Cure Costs unless funded by Buyer) to resolve such disputes with the
applicable non-debtor party, and all such resolutions with respect to any
Assigned Contract shall be acceptable to Buyer in its sole discretion.
(e)    At any time prior to the Designation Deadline, Buyer shall have the
right, which may be exercised in Buyer’s sole discretion, to provide written
notice to Seller of Buyer’s election to designate any Applicable Contract
(including any Contract that is an Assigned Contract immediately before such
designation) (i) as an Excluded Contract and upon such designation such Contract
shall constitute an Excluded Contract and, if applicable, shall cease to
constitute an Assigned Contract or (ii) to the extent not already rejected, as
an Assigned Contract and upon such designation such Contract shall constitute an
Assigned Contract and shall cease to constitute an Excluded Contract. If an
Applicable Contract is subject to a cure dispute or other dispute as to the
assumption or assignment of such Applicable Contract that has not been resolved
to the mutual satisfaction of Buyer and Seller prior to the Designation
Deadline, then the Designation Deadline shall be extended (but only with respect
to such Applicable Contract) to no later than the earliest of (A) the date on
which such dispute has been resolved to the mutual satisfaction of Buyer and
Seller, (B) the date on which such Applicable Contract is deemed rejected by
operation of Sections 365(d)(4) or 1123(b)(2) of the Bankruptcy Code, as
applicable, or (C) the date required by the Bankruptcy Court and set forth in
the Sale Order. The election form executed and delivered pursuant to Section
2.4(d) shall be deemed automatically amended to reflect changes made pursuant to
this Section 2.4(e).
(f)    If Buyer exercises its rights in Section 2.4(e) above to designate an
Applicable Contract (including an Applicable Contract that was an Assigned
Contract immediately before such designation) as an Excluded Contract, there
shall be no change in the Purchase Price as a result of such designation or
change in designation.
(g)    Notwithstanding anything in this Agreement to the contrary, Seller shall
not reject any Applicable Contracts without the prior written consent of Buyer
in its sole discretion; provided that, after the Designation Deadline, Seller
may reject Excluded Contracts without the consent of Buyer so long as such
Applicable Contracts were identified to Buyer in writing prior to the
Designation Deadline. In the event that Seller identifies (whether before or
after the Designation Deadline) any additional Applicable Contracts capable of
being assumed or rejected that were not previously identified as such, Seller
shall promptly notify Buyer of (i) such Applicable Contracts and (ii) Seller’s
good faith estimate of the amount of the Cure Costs payable in respect of each
such Applicable Contract by supplementing Schedule 2.4 as required by Section
2.1(b). For the avoidance

xxxviii
US-DOCS\112434093.5

--------------------------------------------------------------------------------

of doubt, Buyer may designate each such additional Applicable Contract described
in the immediately preceding sentence as an Assigned Contract or Excluded
Contract pursuant to this Section 2.4, notwithstanding the passage of the
Designation Deadline. The election form executed and delivered pursuant to
Section 2.4(c) shall be deemed automatically amended to reflect changes made
pursuant to this Section 2.4(g).
(h)    Notwithstanding anything in this Agreement to the contrary, including
Section 2.4(e) above, the Gathering Agreements shall at all times constitute
Assigned Contracts and shall be assigned to Buyer at the Closing.

2.5    Consents for Applicable Contracts. For all purposes of this Agreement
(including all representations and warranties of Seller contained herein),
Seller shall be deemed to have obtained all required consents (including all

3.4    Closing Settlement Statement; Final Settlement Statement.
(a)    Not less than five Business Days prior to the Closing, Seller shall
prepare and submit to Buyer for review a draft settlement statement (the
“Closing Settlement Statement”) that shall set forth Seller’s good faith
estimate of the Adjusted Purchase Price, reflecting each proposed adjustment to
be made in accordance with this Agreement as of the date of preparation of such
Closing Settlement Statement and the calculation of the adjustments used to
determine such amount (provided that, to the extent actual amounts are not
available for any particular adjustment as of the date of preparation, such
adjustment shall reflect Seller’s good faith estimate based on all information
reasonably available to Seller at the time, including estimated Operating
Expenses and Hydrocarbon revenues attributable to the Assets for the period
between the Effective Time and the month the Closing occurs), together with the
designation of Seller’s accounts for the wire transfers of funds as set forth in
Section 12.3(d). Within three Business Days after receipt of the Closing
Settlement Statement, Buyer will deliver to Seller a written report prepared in
good faith containing all changes that Buyer proposes to be made to the Closing
Settlement Statement, if any (including proposed changes to Seller’s good faith
estimates, where applicable), together with a brief explanation of such changes
(a “Dispute Notice”). The Closing Settlement Statement, as agreed upon by the
Parties, will be used to adjust the Purchase Price at Closing; provided that, if
the Parties cannot agree on any adjustment in the Closing Settlement Statement
prior to the Closing (including with respect to any estimated adjustment), Buyer
shall deposit into the Escrow Account a portion of the Purchase Price equal to
the positive difference between Seller’s proposed adjustment and Buyer’s
proposed adjustment (as set forth in the Dispute Notice) for such disputed
adjustments (adjusted for any amounts therein actually agreed by the Parties
prior to Closing), and such amounts shall be credited towards the Adjusted
Purchase Price at Closing, subject to resolution as between the Parties prior to
the Final Settlement Date or, if applicable, as provided in Section 3.5.
(b)    On or before the date that is 90 days following the Closing Date (or, if
later, 10 days following the resolution of all disputed matters related to Title
Defects and Environmental Defects in accordance with Section 5.2(i) and Section
6.1(f), as applicable), a final settlement statement (the “Final Settlement
Statement”) will be prepared by Seller, based on actual revenues and expenses
and that takes into account all final adjustments made to the Purchase Price and
shows the resulting final Adjusted Purchase Price. The Final Settlement
Statement shall set forth the actual allocation of the amounts required by this
Agreement. Seller shall supply reasonable documentation in the possession of
Seller or any of its Affiliates to support the items for which adjustments are
proposed or made in the Final Settlement Statement and a brief explanation of
any such adjustments and the reasons therefor. As soon as practicable, and in
any event within 15 days after receipt of the Final Settlement Statement, Buyer
will deliver to Seller a Dispute Notice containing any proposed changes to the
Final Settlement Statement and a brief explanation of such changes. Any changes
not included in a Dispute Notice (including any Dispute Notice delivered
pursuant to Section 3.4(a) above) shall be deemed waived, and Seller’s
determinations with respect to all such elements of the Final Settlement
Statement that are not addressed in the Dispute Notice (including any Dispute
Notice delivered pursuant to Section 3.4(a) above) shall prevail. If the final
Adjusted Purchase Price set forth in the Final Settlement Statement is mutually
agreed upon by Seller and Buyer, the Final Settlement Statement and the final
Adjusted Purchase Price, shall be final and binding on the Parties. If the final
Adjusted Purchase Price is (a) more than the Adjusted Purchase Price used at

xlii
US-DOCS\112434093.5

--------------------------------------------------------------------------------

Closing pursuant to Section 3.4(a), Seller shall be entitled to receive from
Buyer the amount of such difference, or (b) less than the Adjusted Purchase
Price used at Closing pursuant to Section 3.4(a), Buyer shall be entitled to
receive from Seller the amount of such difference. To that end, within two
Business Days after the final resolution by the Parties of the final Adjusted
Purchase Price, the Parties shall execute and deliver a joint instruction to
Escrow Agent requiring Escrow Agent to disburse to each Party the funds in the
Escrow Account to which such Party is entitled in accordance with the terms
hereof; provided that, if Seller is owed amounts in excess of the amounts in the
Escrow Account, then Buyer shall promptly (and in any event within five Business
Days following the final resolution by the Parties of the final Adjusted
Purchase Price) pay to Seller via wire transfer to the account designated by
Seller, the amount of any such difference. Notwithstanding anything to the
contrary herein, in no event shall Seller be liable to Buyer for any amounts
pursuant to this Section 3.4(b) for amounts other than amounts in the Escrow
Account. The Parties shall use commercially reasonable efforts to resolve any
disputes related to the final Adjusted Purchase Price; provided that, if the
Parties are unable to resolve any such disputes (to the extent set forth in a
timely delivered Dispute Notice) within 120 days after the Closing Date (the
“Final Settlement Date”), then the final Adjusted Purchase Price shall be
determined in accordance with Section 3.5.

3.5    Disputes. If Seller and Buyer are unable to resolve the matters addressed
in a Dispute Notice (if any) by the Final Settlement Date, each of Buyer and
Seller shall within 14 Business Days thereafter, summarize its position with
regard to such dispute in a written document of ten pages or less and submit
such summaries to the Houston, Texas office of Deloitte Touche Tohmatsu Limited
(“Deloitte”) (or if Deloitte is unable or unwilling to serve as arbitrator
within 20 days after receipt of a written request from the Parties to serve and
absent agreement by the Parties as to a replacement for such arbitrator within
ten Business Days after notification that Deloitte is unable or unwilling to
serve, the arbitrator shall be selected by the Houston, Texas office of the AAA)
(the “Accounting Arbitrator”), together with the Dispute Notice and any other
documentation such Party may desire to submit. The Accounting Arbitrator shall
also be furnished with a copy of this Agreement. The Parties shall instruct the
Accounting Arbitrator that, within 20 Business Days after receiving the Parties’
respective submissions, the Accounting Arbitrator shall render a decision
choosing either Seller’s position or Buyer’s position with respect to each
matter addressed in any Dispute Notice, whichever complies more closely to the
terms of the Agreement and the materials described above. The costs of such
Accounting Arbitrator shall be borne one-half by Seller and one-half by Buyer.
Any decision rendered by the Accounting Arbitrator pursuant hereto shall be
final, conclusive and binding on Seller and Buyer and will be enforceable
against each of the Parties in any court of competent jurisdiction. The final
Adjusted Purchase Price determined by the Accounting Arbitrator pursuant to this
Section 3.5 shall be final and binding on the Parties, without right of appeal
and enforceable by either party in any court of competent jurisdiction. The
Accounting Arbitrator shall be authorized to resolve only the specific disputed
aspects of the Final Settlement Statement submitted by the Parties as provided
above and may not award damages, interest or penalties to any Party with respect
to any matter, notwithstanding any AAA Rules to the contrary. Within two
Business Days after the final resolution by the Accounting Arbitrator of the
matters addressed in the Dispute Notice, the Parties shall execute and deliver a
joint instruction to Escrow Agent requiring Escrow Agent to disburse to each
Party the funds in the Escrow Account to which such Party is entitled in
accordance with the terms of such final resolution; provided that, if Seller is
owed amounts in

xliii
US-DOCS\112434093.5

--------------------------------------------------------------------------------

excess of the amounts in the Escrow Account, then Buyer shall promptly (and in
any event within five Business Days following the final resolution by the
Parties of the final Adjusted Purchase Price) pay to Seller via wire transfer to
the account designated by Buyer, the amount of any such difference; provided
that, notwithstanding anything to the contrary herein, in no event shall Seller
be liable to Buyer for any amounts pursuant to this Section 3.5 for amounts
other than amounts in the Escrow Account.

3.6    Allocated Values. Subject to adjustment as set forth herein, the
“Allocated Value” for each Title Well included in the Assets shall equal the
amount set forth for such Title Well on Schedule 3.6, and such Allocated Values
shall be used in calculating adjustments to the Purchase Price as provided
herein.

3.7    Allocation for Imbalances. Notwithstanding anything to the contrary in
this Agreement, if, prior to Closing, either Party discovers an error in the
Imbalances set forth in Schedule 7.15, then the Purchase Price shall be further
adjusted at Closing pursuant to Section 3.3(a)(iv), Section 3.3(a)(v), Section
3.3(b)(vi) or Section 3.3(b)(vii), as applicable (but there shall be no deemed
adjustment to Schedule 7.15 for purposes of determining whether the condition to
Closing in Section 10.1 has been satisfied).

3.8    Withholding. Buyer shall be entitled to deduct and withhold from any
consideration otherwise payable or deliverable to Seller pursuant to this
Agreement such amounts as may be required to be deducted or withheld therefrom
under any Law. The Parties shall cooperate in good faith to minimize, to the
extent permissible under applicable Law, the amount of any such deduction or
withholding. To the extent such amounts are so deducted or withheld, and
remitted to the applicable Governmental Authority in accordance with applicable
Law, such amounts shall be treated for all purposes as having been paid to the
Person to whom such amounts would otherwise have been paid absent such deduction
or withholding.

ARTICLE IV

(a)    From and after the Execution Date and up to and including the Closing
Date (or earlier termination of this Agreement) but subject to (i) the other

Third Parties that are required pursuant to the terms of the Leases, easements
and Applicable Contracts (including any restrictions therein related to access

reasonable efforts to obtain without any obligation to incur any out-of-pocket

Buyer and its Affiliates and their respective officers, employees, agents,
accountants, attorneys, investment bankers, consultants and other authorized

Representatives’ title due diligence activities with respect to the Assets.
(b)    From and after the Execution Date to the Closing Date (or earlier
termination of this Agreement), subject to (i) the other provisions of this
Section 4.1, and (ii) obtaining any consents or waivers from Third Parties that
are required pursuant to the terms of the Leases, easements and Applicable
Contracts (including any restrictions therein related to access during hunting

or conduct any testing, boring, sampling, drilling or other invasive
investigation activities (in each case) on or with respect to any of the Assets
without the prior written consent of Seller, which consent may be withheld in

applicable ASTM International Standards) with respect to any Assets where Seller
does not have the authority to grant access for such due diligence; provided
that Seller shall use commercially reasonable efforts to obtain such access
without any obligation to incur any out-of-pocket cost or expense or provide any
other consideration. In the event a Phase II Environmental Site Assessment is
reasonably necessary to determine (A) whether an Environmental Condition exists
or (B) the Remediation Amount associated with an asserted Environmental
Condition, in either case, on a Property operated by Seller, Buyer may request
the right to conduct a Phase II Environmental Site Assessment on the affected
Property. If Seller denies such a request, Buyer shall have the right to cause

assessment of the Assets, and to the extent required by any Third Party
operator, execute and deliver any access agreement required by such Third Party

from Buyer’s (or the Buyer Representatives’) environmental due diligence with
respect to the Assets, including any data generated in association with any
Phase I Environmental Site Assessment conducted in accordance with Section
4.1(b). Seller shall not be deemed by its receipt of said documents or otherwise

to the condition of the Assets or to the accuracy of said documents or the
information contained therein.
(f)    Upon completion of Buyer’s due diligence, Buyer shall remove all
equipment, tools or other property brought onto the Assets in connection with
Buyer’s (or any Buyer Representative’s) due diligence investigation and to the
extent there exists after such due diligence investigation any damage upon the
Assets, Seller shall (i) repair all damage done to the Assets (including the
real property and other assets associated therewith) in connection with Buyer’s
(or any Buyer Representative’s) due diligence investigation, and (ii) restore
the Assets (including the real property and other assets associated therewith)

If the Closing should occur, the foregoing confidentiality restriction on Buyer,
including the Confidentiality Agreement, shall terminate (except as to the

Agreement shall not relieve any party thereto from any liability thereunder for
the breach of such agreement prior to the Execution Date.

Conveyance), Buyer shall be deemed to have waived, and Seller shall have no
liability for, any Title Defect or other title matter that Buyer fails to assert
as a Title Defect by a Title Defect Notice received by Seller on or before the
Defect Claim Date. To be effective, each Title Defect Notice shall be in writing
and shall include: (i) a description of the alleged Title Defect, (ii)
identification of the Subject Property affected by the Title Defect (such
Subject Property, each, as applicable, a “Title Defect Property”), (iii) the
Allocated Value of each Title Defect Property, (iv) supporting documents
available to Buyer reasonably necessary for Seller to identify the existence of
the alleged Title Defect, and (v) the amount by which Buyer reasonably believes
the Allocated Value of each Title Defect Property is reduced by the alleged
Title Defect and the computations (with reasonable supporting detail) upon which
Buyer’s belief is based. To give Seller an opportunity to commence reviewing and
curing Title Defects, Buyer agrees to use its reasonable efforts to give Seller
weekly written notice of all Title Defects discovered by Buyer (together with
any Title Benefits discovered by Buyer) during the preceding period after the
Execution Date and prior to delivery of such notice, which notice may be
preliminary in nature and may be supplemented on or prior to the Defect Claim
Date; provided that failure of Buyer to deliver a preliminary notice of any such
Title Defect shall not be deemed to waive or otherwise prejudice Buyer’s right
to assert any Title Defect on or before the Defect Claim Date. Buyer shall also
promptly furnish Seller with written notice of any Title Benefit that is
discovered by any Buyer Representative prior to the Defect Claim Date.
(b)    Title Benefit Notices. In addition to Title Benefits reported by Buyer
pursuant to Section 5.2(a), Seller shall have the right, but not the obligation,
to deliver to Buyer on or before

--------------------------------------------------------------------------------

the Defect Claim Date a notice meeting the requirements of this Section 5.2(b)
(collectively, the “Title Benefit Notices”, and each individually, a “Title
Benefit Notice”) setting forth any additional matters that, in Seller’s
reasonable opinion, constitute Title Benefits and that Seller intends to assert
as a Title Benefit pursuant to this Article V. To be effective, each Title
Benefit Notice shall be in writing and shall include: (i) a description of the
alleged Title Benefit, (ii) the Subject Property affected by the Title Benefit
(each, as applicable, a “Title Benefit Property”), (iii) the Allocated Value of
the Title Benefit Property, (iv) supporting documents available to Seller
reasonably necessary for Buyer to identify the existence of the alleged Title
Benefit, and (v) the amount by which Seller reasonably believes the Allocated
Value of each Title Benefit Property should be increased by the alleged Title
Benefit and the computations (with reasonable supporting detail) upon which
Seller’s belief is based. Except for Title Benefits that Buyer is required to
report to Seller pursuant to Section 5.2(a), Seller shall be deemed to have
waived, and Buyer shall not have any liability for, any Title Benefit that
Seller fails to assert as a Title Benefit by a Title Benefit Notice received by
Buyer on or before the Defect Claim Date.
(c)    Seller’s Right to Cure. Notwithstanding anything to the contrary herein,
Seller shall have the right, but not the obligation, by giving written notice of
such election to Buyer on or before the Closing Date, to attempt, at its sole
cost, to cure, at any time prior to the expiration of 90 days following the
Closing (the “Cure Period”), any Title Defects of which it has timely received a
Title Defect Notice from Buyer. In the event Seller elects prior to Closing to
cure an asserted Title Defect that is not cured at Closing, Seller shall so
notify Buyer, and at Closing, (i) the applicable Title Defect Property shall be
included in the Assets conveyed to Buyer at Closing, (ii) the unadjusted
Purchase Price shall be reduced by an amount equal to the Title Defect Amount
for such asserted Title Defect, and (iii) Buyer shall deposit the Title Defect
Amount of the asserted Title Defect into the Escrow Account. Notwithstanding the
foregoing, in the event that (A) the rejection of a Contract would cure any
Title Defect and (B) Buyer, in its sole discretion, elects to reject such
Contract pursuant to this Agreement, then such Title Defect shall be deemed to
have been cured for all purposes hereunder. In the event that the asserted Title
Defect is completely cured during the Cure Period, within two Business Days
after the day upon which such asserted Title Defect is cured, the Parties shall
execute and deliver a joint instruction to Escrow Agent requiring Escrow Agent
to disburse to Seller an amount equal to the Title Defect Amount for the
applicable Title Defect from the Escrow Account. In the event that the asserted
Title Defect is not completely cured during the Cure Period, on the later to
occur of (i) the day that is two Business Days after the expiration of the Cure
Period, and (ii) the day that is two Business Days after the final resolution of
any Title Dispute regarding such asserted Title Defect, the Parties shall
execute and deliver a joint instruction to Escrow Agent requiring Escrow Agent
to disburse to each Party the funds in the Escrow Account to which such Party is
entitled in respect of the applicable Title Defect. The foregoing provisions of
this Section 5.2(c) shall be subject to the provisions of Section 5.2(i) with
respect to any valid Title Dispute (including with respect to the Title Defect
Amount or the extent of curative with respect to the applicable Title Defect).
(d)    Remedies for Title Defects. Subject to (v) Seller’s continuing right to
dispute the existence of a Title Defect and the Title Defect Amount asserted
with respect thereto, (w) the rights of Seller pursuant to Section 14.1(c), (x)
the Individual Title Defect Threshold, (y) the Aggregate Deductible and (z)
Seller’s ongoing right to cure any Title Defect under Section 5.2(c),

l
US-DOCS\112434093.5

--------------------------------------------------------------------------------

if any Title Defect timely asserted by Buyer in accordance with Section 5.2(a)
is not waived in writing by Buyer or cured by Closing, then in connection with
the Closing (unless, as of the Closing, the Parties are in disagreement with
respect to the existence of such Title Defect or any associated Title Defect
Amount, in each of which case the applicable Title Dispute shall, unless
otherwise agreed by the Parties, be addressed pursuant to Section 5.2(i)),
Seller shall, at its sole option and discretion, elect one or more of the
following remedies for such Title Defect:
(i)    Seller will convey the entirety of the Title Defect Property that is
subject to such Title Defect to Buyer, together with all associated Assets, at
Closing, and make an accompanying reduction to the Purchase Price in an amount
determined pursuant to Section 5.2(f) or Section 5.2(i) as being the value of
such Title Defect to the extent affecting the applicable Title Defect Property
(the “Title Defect Amount”); or
(ii)    if and only if the aggregate Title Defect Amount for a Title Defect
Property equals or exceeds the Allocated Value thereof, Seller may retain the
entirety of the Title Defect Property that is subject to such Title Defect,
together with all associated Assets (in which case, such Assets shall become
Excluded Assets hereunder), and reduce the Purchase Price by an amount equal to
the Allocated Value of such Title Defect Property.
(e)    Remedies for Title Benefits. Subject to Buyer’s right to dispute any
Title Benefit or associated Title Benefit Amount, if any Title Benefits for
which the Title Benefit Amount exceeds the Individual Title Defect Threshold are
identified by Buyer pursuant to Section 5.2(a) or are timely asserted by Seller
in accordance with Section 5.2(b) then, as Seller’s sole and exclusive remedy
for any such Title Benefits, the aggregate amount of all such Title Benefit
Amounts (solely to the extent such Title Benefit Amounts exceed the Individual
Title Defect Threshold) shall be applied as to offset the aggregate Title Defect
Amounts. For the avoidance of doubt, Title Benefit Amounts shall in no event
increase the Purchase Price and shall, instead, solely offset Title Defect
Amounts.
(f)    Title Defect Amount. The Title Defect Amount resulting from a Title
Defect shall be the amount by which the Allocated Value of the affected Title
Defect Property is reduced as a result of the existence of such Title Defect and
shall be determined in accordance with the following terms and conditions:
(i)    if Seller and Buyer agree on the Title Defect Amount, then that amount
shall be the Title Defect Amount;
(ii)    if the Title Defect is an obligation, Encumbrance or burden that is
undisputed and liquidated in amount, then the Title Defect Amount shall be the
amount necessary to be paid to permanently and fully discharge the Title Defect
from the Title Defect Property;
(iii)    if the Title Defect Property is a Title Well and the Title Defect
represents a decrease in the Net Revenue Interest for such Title Defect Property
such that the actual Net Revenue Interest for such Title Defect Property is less
than the Net Revenue Interest set forth in Exhibit A-1 for such Title Defect
Property, and the Working Interest for

li
US-DOCS\112434093.5

--------------------------------------------------------------------------------

such Title Well is reduced proportionately, then the Title Defect Amount shall
be the product of the Allocated Value of such Title Defect Property, multiplied
by a fraction, the numerator of which is the amount of such Net Revenue Interest
decrease and the denominator of which is the Net Revenue Interest set forth for
such Title Defect Property in Exhibit A-1; provided that, if the Title Defect
does not affect the Title Defect Property throughout the entire life of such
Title Defect Property, then the Title Defect Amount determined under this
Section 5.2(f)(iii) shall be reduced to take into account the applicable time
period only;
(iv)    if the Title Defect represents an obligation or Encumbrance upon or
other defect in title affecting the Title Defect Property of a type not
described above, the Title Defect Amount shall be determined by taking into
account the Allocated Value of the Title Defect Property, the portion of the
Title Defect Property affected by the Title Defect, the legal effect of the
Title Defect, the potential economic effect of the Title Defect over the life of
the Title Defect Property and such other reasonable factors as are necessary to
make a proper evaluation;
(v)    the Title Defect Amount with respect to a Title Defect Property shall be
determined without duplication of any costs or losses included in another Title
Defect Amount hereunder; and
(vi)    notwithstanding anything to the contrary in this Article V, except with
respect to any Title Defect for which the Title Defect Amount is determined
pursuant to Section 5.2(f)(ii), the aggregate Title Defect Amounts attributable
to the effects of all Title Defects upon any Title Defect Property (whether
related to an adjustment to the Purchase Price or any other remedy provided by
Seller hereunder) shall not exceed the Allocated Value of such Title Defect
Property.
(g)    Title Benefit Amount. The Title Benefit Amount resulting from a Title
Benefit shall be determined in accordance with the following methodology, terms
and conditions:
(i)    if Buyer and Seller agree on the Title Benefit Amount, then that amount
shall be the Title Benefit Amount;
(ii)    if the Title Benefit Property is a Title Well and the Title Benefit
represents an increase in the Net Revenue Interest for such Title Benefit
Property such that the actual Net Revenue Interest for such Title Benefit
Property is greater than the Net Revenue Interest stated in Exhibit A-1 for such
Title Benefit Property, and the Working Interest is increased proportionately,
then the Title Benefit Amount shall be the product of the Allocated Value of
such Title Benefit Property, multiplied by a fraction, the numerator of which is
the value of such Net Revenue Interest increase and the denominator of which is
the Net Revenue Interest set forth for such Title Benefit Property in Exhibit
A-1, provided that, if the increased Net Revenue Interest does not affect the
Title Benefit Property throughout the entire life of such Title Benefit
Property, then the Title Benefit Amount determined under this Section 5.2(g)(ii)
shall be reduced to take into account the applicable time period only; and

lii
US-DOCS\112434093.5

--------------------------------------------------------------------------------

(iii)    if the Title Benefit is of a type not described above, then the Title
Benefit Amounts shall be determined by taking into account the Allocated Value
of the Title Benefit Property, the portion of such Title Benefit Property
affected by such Title Benefit, the legal effect of the Title Benefit, the
potential economic effect of the Title Benefit over the life of such Title
Benefit Property and such other reasonable factors as are necessary to make a
proper evaluation.
(h)    Title Threshold and Deductible. Notwithstanding anything herein to the
contrary, (i) in no event shall there be any adjustments to the Purchase Price
or any other remedy provided by Seller hereunder for any individual Title Defect
for which the Title Defect Amount applicable thereto does not exceed $50,000
(the “Individual Title Defect Threshold”); and (ii) in no event shall there be
any adjustments to the Purchase Price for any Title Defect for which the Title
Defect Amount applicable thereto exceeds the Individual Title Defect Threshold
unless and until (A) the sum of (1) the Title Defect Amounts of all such Title
Defects that exceed the Individual Title Defect Threshold, in the aggregate
(excluding any Title Defect Amounts attributable to (v) Title Defects cured by
Seller, and (w) Title Defect Properties retained by Seller pursuant to
Section 5.2(d)(ii)), net of any offsetting Title Benefit Amounts in accordance
with Section 5.2(e), plus (2) the Remediation Amounts of all Environmental
Defects that exceed the Individual Environmental Defect Threshold, in the
aggregate (excluding any Remediation Amounts attributable to (x) Environmental
Defects cured or Remediated by Seller, and (y) Environmental Defect Properties
that are retained by Seller pursuant to Section 6.1(c)(ii)), exceeds (B) the
Aggregate Deductible, in which case Buyer shall be entitled to remedies for such
Title Defects to the extent, but only to the extent, that the Title Defect
Amounts with respect thereto are in excess of such Aggregate Deductible.
(i)    Title Dispute Resolution. Seller and Buyer shall attempt in good faith to
agree on all Title Defects, Title Benefits, Title Defect Amounts and Title
Benefit Amounts (any dispute with respect to the foregoing matters, including
the existence, extent of or any cure of any Title Defect, collectively “Title
Disputes”) prior to the Closing, or, if the applicable Title Dispute relates to
any Title Defect Property for which Seller has attempted to cure the alleged
Title Defect(s) following Closing and prior to the expiration of the Cure
Period, then prior to the date that is ten Business Days following the
expiration of the Cure Period. If Seller and Buyer are unable to agree within
the above applicable time period, the Title Disputes arbitrated shall be
exclusively and finally resolved pursuant to this Section 5.2(i). Nothing herein
shall operate to cause Closing to be delayed on account of any arbitration
conducted pursuant to this Section 5.2(i) with respect to any Title Defect
properly asserted by Buyer or any Title Benefit properly asserted by Seller
prior to the Defect Claim Date, and to the extent any adjustments are not agreed
upon by the Parties as of the Closing, unless Seller has elected to retain the
applicable Title Defect Property pursuant to Section 5.2(d)(ii), the affected
Title Defect Property shall be assigned to Buyer at Closing and the Purchase
Price shall be reduced by an amount equal to the Title Defect Amount applicable
for such Title Defect, which amount (including any disputed amounts) shall be
paid into the Escrow Account at Closing and remain therein until such dispute is
resolved pursuant to this Section 5.2(i). Any Title Disputes shall be submitted
to an arbitrator with at least ten years’ experience in oil and gas titles
including properties in the regional area in which the Subject Properties are
located (the “Title Arbitrator”). If the Parties are unable to agree on the
selection of the Title Arbitrator within ten Business Days

liii
US-DOCS\112434093.5

--------------------------------------------------------------------------------

of the Parties agreeing to submit a Title Dispute to the Title Arbitrator for
determination or, in the case where the Parties have not so agreed, within ten
Business Days of the non-submitting Party receiving written notice from the
submitting Party stating that such Party has elected to submit a Title Dispute
to arbitration in accordance with this Section 5.2(i), the AAA shall make the
necessary appointment (which Title Arbitrator shall not have worked as an
employee, outside counsel or as a consultant for any Party or its Affiliates
during the five year period preceding the arbitration or have any financial
interest in the dispute). The place of arbitration shall be Houston, Texas, and
the arbitration shall be conducted in accordance with the AAA Rules, to the
extent such rules do not conflict with the terms of this Section 5.2. The
Parties, within ten days after the Title Arbitrator is appointed, shall submit
written summaries of their positions regarding each Title Dispute. The Parties
shall instruct the Title Arbitrator to make a determination, choosing either
Seller’s position or Buyer’s position with respect to each Title Dispute,
whichever the Title Arbitrator determines complies more closely to the terms of
this Agreement, within 20 Business Days after the submission of the Parties’
summaries of the Title Disputes to the Title Arbitrator, and such determination
shall be final and binding upon both Parties, without right of appeal. The costs
of the Title Arbitrator shall be borne one-half by Seller and one-half by Buyer.
In making its determination, the Title Arbitrator shall be bound by the terms of
this Article V and, subject to the foregoing, may consider such other matters as
in the opinion of the Title Arbitrators are necessary to make a proper
determination. The Title Arbitrator shall act for the limited purpose of
determining the specific Title Disputes submitted by either Party and may not
award damages, interest or penalties to either Party with respect to any Title
Dispute. Seller and Buyer shall each bear its own legal fees and other costs of
presenting its case to the Title Arbitrator. Within two Business Days after the
Title Arbitrator delivers written notice to Buyer and Seller of its award with
respect to a Title Dispute, and subject to Section 5.2(h), the Parties shall
execute and deliver a joint instruction to Escrow Agent requiring Escrow Agent
to disburse to each Party the funds in the Escrow Account to which such Party is
entitled in respect of the applicable Title Dispute.

5.3    Casualty or Condemnation Loss.
(a)    Notwithstanding anything herein to the contrary, from and after the
Effective Time if Closing occurs, with respect to the Assets, Buyer shall assume
all risk of loss, including with respect to (i) production of Hydrocarbons
through normal depletion (including watering out of any Well, collapsed casing
or sand infiltration of any Well) and (ii) the depreciation of any Asset due to
ordinary wear and tear, and, in each case, Buyer shall not assert such matters
as any Casualty or Condemnation Loss or Title Defect hereunder.
(b)    If, after the Execution Date but prior to the Closing Date, any portion
of the Assets is damaged or destroyed or otherwise impaired by fire, explosion,
tornado, hurricane, earthquake, earth movement, flood, water damage or other
similar casualty or is taken in condemnation or under right of eminent domain
(in each case, a “Casualty or Condemnation Loss”) then Buyer shall nevertheless
be required to close the transactions contemplated by the Agreement without any
change to the Purchase Price and Seller shall pay to Buyer all sums paid to
Seller by Third Parties by reason of such Casualty or Condemnation Loss insofar
as with respect to the Assets and shall assign, transfer and set over to Buyer
or subrogate Buyer to all of Seller’s and its Affiliates’ right, title and
interest (if any) in insurance claims, unpaid awards and other rights against
Third

liv
US-DOCS\112434093.5

--------------------------------------------------------------------------------

Parties (excluding any Liabilities, other than insurance claims, of or against
any Seller Indemnified Parties) arising out of such Casualty or Condemnation
Loss insofar as with respect to the Assets; provided, however, that Seller shall
reserve and retain (and Buyer shall assign to Seller) all rights, title,
interests and claims against Third Parties for the recovery of Seller’s costs
and expenses incurred prior to the Closing in pursuing or asserting any such
insurance claims or other rights against Third Parties with respect to any such
Casualty or Condemnation Loss. Except as expressly set forth hereinabove, Seller
shall retain all rights to insurance, condemnation awards and other claims
against Third Parties with respect to the casualty or taking except to the
extent the Parties otherwise agree in writing.

5.4    Preferential Purchase Rights and Consents to Assign.
(a)    With respect to each Preferential Purchase Right set forth on Schedule
7.9, within five Business Days after the Execution Date, Seller shall send to
the holder of each such Preferential Purchase Right a notice in compliance with
the contractual provisions applicable to such Preferential Purchase Right
requesting a waiver of such right. With respect to each Preferential Purchase
Right that is not set forth on Schedule 7.9 but is discovered by Seller prior to
Closing, Seller shall send to the holder of each such Preferential Purchase
Right a notice in compliance with the contractual provisions applicable to such
Preferential Purchase Right requesting a waiver of such right as soon as
reasonably practicable (but in no event later than two Business Days after
discovery of any such Preferential Purchase Right). Any Preferential Purchase
Right must be exercised subject to all terms and conditions set forth in this
Agreement, and the consideration payable under this Agreement for the purposes
of all Preferential Purchase Right notices shall be the Allocated Value of the
applicable Asset (as adjusted herein).
(i)    If, prior to Closing, any holder of a Preferential Purchase Right
notifies Seller that it intends to consummate the acquisition of the Assets to
which its Preferential Purchase Right applies or if the time for exercising such
Preferential Purchase Right has not expired (and the holder of such right has
not waived such right), then the Assets subject to such Preferential Purchase
Right shall be excluded from the Assets to be assigned to Buyer at Closing (and
shall be considered Excluded Assets hereunder, but only to the extent of the
portions of such Assets affected by the Preferential Purchase Right), and the
Purchase Price shall be reduced by the Allocated Value of such Assets (or
portions thereof) so excluded. Seller shall be entitled to all consideration
given by any Person exercising a Preferential Purchase Right prior to Closing.
If such holder of such Preferential Purchase Right thereafter fails to
consummate the acquisition of the Assets (or portions thereof) covered by such
Preferential Purchase Right on or before 120 days following the Closing Date or
the time for exercising such Preferential Purchase Right expires without
exercise by the holder thereof, (A) Seller shall so notify Buyer and (B) Seller
shall assign, on the tenth Business Day following termination of such right
without consummation or exercise, such Assets (or portions thereof) that were so
excluded to Buyer pursuant to an instrument in substantially the same form as
the Assignment or Deed, as applicable (and such Assets (or portions thereof)
shall no longer be considered Excluded Assets), and Buyer, contemporaneously
with said assignment, shall pay by wire transfer in same day funds to Seller, to
an account designated by Seller, the amount by which the Purchase Price was

lv
US-DOCS\112434093.5

--------------------------------------------------------------------------------

reduced at Closing with respect to such excluded Assets (or portions thereof),
subject to any adjustment in the allocable portion of the Purchase Price
affecting such Asset (or portions thereof) pursuant to Section 3.3.
(ii)    All Assets for which any applicable Preferential Purchase Right has been
waived, or as to which the period to exercise the applicable Preferential
Purchase Right has expired (and such Preferential Purchase Right has not been
exercised), in each case, prior to Closing, shall be sold to Buyer at Closing
pursuant to the provisions of this Agreement and Buyer shall be deemed to have
assumed any and all Liabilities with respect to such Preferential Purchase Right
as part of the Assumed Obligations hereunder and Buyer shall have no claim
against, and hereby releases and indemnifies the Seller Indemnified Parties from
any Liability with respect to such Preferential Purchase Right.
(b)    Within five Business Days after the Execution Date, Seller shall send to
the holder of each Applicable Schedule 7.4 Consent a notice in compliance with
the contractual provisions applicable to such Applicable Schedule 7.4 Consent
seeking such holder’s consent to the transactions contemplated hereby. With
respect to each Consent (A) relating to an Applicable Contract for which the
counterparty’s consent to assignment would be required for such Applicable
Contract to be assumed and assigned to Buyer, after giving effect to sections
365(c)(1) and 365(f)(1) of the Bankruptcy Code or (B) that burdens a Lease, but
which Consent is not set forth on Schedule 7.4 and is discovered by Seller
(including, if applicable, any such Consent that is identified by Buyer) prior
to Closing, all such Consents shall thereafter be Applicable Schedule 7.4
Consents hereunder and Seller shall send to the holder of each such Consent a
notice in compliance with the contractual provisions applicable to such Consent
seeking such holder’s consent to the transactions contemplated hereby as soon as
reasonably practicable (but in no event later than two Business Days after
discovery of any such Consent).
(i)    If Seller fails to obtain a Applicable Schedule 7.4 Consent prior to
Closing and (1) the failure to obtain such Applicable Schedule 7.4 Consent would
cause the assignment of the Assets affected thereby to Buyer to be void or
voidable, (2) the failure to obtain such Applicable Schedule 7.4 Consent could
reasonably result in the termination of a Lease or Assigned Contract under the
express terms thereof or (3) a Party holding such Applicable Schedule 7.4
Consent right has objected to the assignment of the affected Asset in accordance
with the terms of the relevant Applicable Schedule 7.4 Consent right and the
assignment of the affected Asset would not be permitted under the Bankruptcy
Code (each Applicable Schedule 7.4 Consent meeting the requirements of either
clause (1), clause (2) or clause (3) above, a “Required Consent”), then, unless
the Bankruptcy Court has entered an order approving (or in the case of clause
(3), such objection is resolved to permit) the sale and assignment of the
affected Asset to Buyer pursuant to this Agreement without obtaining such
Required Consent, the Assets (or portions thereof) affected by such un-obtained
Required Consent shall be excluded from the Assets to be assigned to Buyer at
Closing (and shall be considered Excluded Assets hereunder) and the Purchase
Price shall be reduced by the Allocated Value(s) of such Assets (or portions
thereof) so excluded. In the event that any such Required Consent with respect
to any such excluded Asset (or portion thereof) is obtained within 120 days
after the Closing (or if during such 120-day period the

lvi
US-DOCS\112434093.5

--------------------------------------------------------------------------------

Bankruptcy Court enters an order providing that such Required Consent is not
required to consummate the sale of the affected Assets to Buyer), then, (A)
Seller shall so notify Buyer and (B) on the tenth Business Day after the date
such Consent is obtained Seller shall assign the Assets (or portions thereof)
that were so excluded as a result of such previously un-obtained Consent to
Buyer pursuant to an instrument in substantially the same form as the Assignment
or Deed, as applicable (and such Assets (or portions thereof) shall no longer be
considered Excluded Assets hereunder) and, contemporaneously with said
assignment, Buyer shall pay by wire transfer in same day funds to Seller, to an
account designated by Seller, the amount by which the Purchase Price was reduced
at Closing with respect to such excluded Assets (or portions thereof), subject
to any adjustment in the allocable portion of the Purchase Price affecting such
Asset (or portions thereof) pursuant to Section 3.3.
(ii)    If Seller fails to obtain a Consent prior to Closing and such Consent is
not a Required Consent (or if prior to Closing the Bankruptcy Court enters an
order providing that a Required Consent is not required to consummate the sale
of the affected Assets to Buyer), then the Assets (or portions thereof) subject
to such un-obtained Consent shall nevertheless be assigned by Seller to Buyer at
Closing as part of the Assets and Buyer shall be deemed to have assumed any and
all Liabilities for the failure to obtain any such Consent as part of the
Assumed Obligations hereunder and Buyer shall have no claim against the Seller
Indemnified Parties from any Liability for, the failure to obtain such Consent.
(iii)    Prior to Closing and during the 120-day period after Closing with
respect to any unobtained Required Consents with respect to which the Bankruptcy
Court shall not have entered an order approving the sale and assignment of the
affected Assets to Buyer pursuant to this Agreement without obtaining such
Required Consent, Seller shall use its commercially reasonable efforts to obtain
all Consents; provided, however, that Seller shall not be required to incur any
Liability, pay any money or provide any other consideration in order to obtain
any such Consent. Buyer shall use its commercially reasonable efforts (without
any obligation to incur any Liability, pay money or provide any other
consideration) to assist and cooperate with Seller in furtherance of Seller’s
efforts pursuant to this Section 5.4(b)(iii).

ARTICLE VI    
ENVIRONMENTAL MATTERS

6.1    Environmental Defects.
(a)    Assertions of Environmental Defects. On or before the Defect Claim Date,
Buyer may deliver claim notices to Seller meeting the requirements of this
Section 6.1(a) (collectively, the “Environmental Defect Notices,” and each
individually, an “Environmental Defect Notice”) setting forth any matters that,
in Buyer’s reasonable opinion, constitute Environmental Defects and that Buyer
intends to assert as Environmental Defects pursuant to this Section 6.1.
Notwithstanding anything to the contrary herein, Buyer shall not be entitled to
deliver Environmental Defect Notices in respect of any matters disclosed on
Schedule 7.24, and no such matters shall be Environmental Defects for purposes
of this Agreement. For all purposes of this Agreement and notwithstanding
anything herein to the contrary, but subject to Seller’s

lvii
US-DOCS\112434093.5

--------------------------------------------------------------------------------

representations and warranties in Section 7.20 and in the certificate delivered
by Seller at Closing, and without limiting Buyer’s conditions to Closing set
forth in Article X (including as set forth in Section 10.4), the provisions of
Section 6.1(c) shall be the exclusive right and remedy of Buyer with respect to
any Environmental Defect and Buyer shall be deemed to have waived, and Seller
shall have no liability for, any Environmental Defect that Buyer fails to assert
as an Environmental Defect by an Environmental Defect Notice received by Seller
on or before the Defect Claim Date. To be effective, each Environmental Defect
Notice shall be in writing, and shall include (i) a description of the alleged
Environmental Defect (including the applicable Environmental Law(s) violated or
implicated thereby), (ii) identification of the Property affected by the alleged
Environmental Defect (each such Property, as applicable, an “Environmental
Defect Property”), (iii) if applicable, the Allocated Value of each
Environmental Defect Property, (iv) supporting documents available to Buyer
reasonably necessary for Seller to identify the existence of the alleged
Environmental Defect, and (v) a calculation (with reasonable supporting detail)
of the Remediation Amount that Buyer asserts is attributable to the alleged
Environmental Defect. To give Seller an opportunity to commence reviewing and
curing Environmental Defects, Buyer agrees to use its reasonable efforts to give
Seller weekly written notice of all Environmental Defects discovered by Buyer
during the preceding period after the Execution Date and prior to delivery of
such notice, which notice may be preliminary in nature and may be supplemented
on or prior to the Defect Claim Date; provided that failure of Buyer to deliver
a preliminary notice of any such Environmental Defect shall not be deemed to
waive or otherwise prejudice Buyer’s right to assert any Environmental Defect on
or before the Defect Claim Date. Buyer’s calculation of the Remediation Amount
included in the Environmental Defect Notice must describe in reasonable detail
the Remediation proposed for the Environmental Condition that gives rise to the
asserted Environmental Defect and identify all assumptions used by Buyer in
calculating the Remediation Amount, including the standards that Buyer asserts
must be met to comply with Environmental Laws.
(b)    Seller’s Right to Cure. Notwithstanding anything to the contrary herein,
Seller shall have the right, but not the obligation, to attempt, at its sole
cost, to Remediate, at any time during the Cure Period, any Environmental
Defects of which it has timely received an Environmental Defect Notice from
Buyer. In the event Seller elects prior to Closing to cure an asserted
Environmental Defect that is not cured at Closing, Seller shall so notify Buyer,
and at Closing, Buyer shall deposit the Environmental Defect amount of the
asserted Environmental Defect into the Escrow Account at Closing. In the event
that the asserted Environmental Defect is completely Remediated during the Cure
Period, within two Business Days after the day upon which such asserted
Environmental Defect is completely Remediated, the Parties shall execute and
deliver a joint instruction to Escrow Agent requiring Escrow Agent to disburse
to Seller an amount equal to the Environmental Defect amount for the applicable
Environmental Defect from the Escrow Account. In the event that the asserted
Environmental Defect is not completely Remediated during the Cure Period, on the
later to occur of (i) the day that is two Business Days after the expiration of
the Cure Period, and (ii) the day that is two Business Days after the final
resolution of any Environmental Dispute regarding such asserted Environmental
Defect, the Parties shall execute and deliver a joint instruction to Escrow
Agent requiring Escrow Agent to disburse to each Party the funds in the Escrow
Account to which such Party is entitled in respect of the applicable
Environmental Defect.

(c)    Remedies for Environmental Defects. Subject to (v) Seller’s continuing
right to dispute the existence of an Environmental Defect and the Remediation
Amount asserted with respect thereto, (w) the rights of Seller pursuant to
Section 14.1(c), (x) the Individual Environmental Defect Threshold, (y) the
Aggregate Deductible, and (z) Seller’s ongoing right to Remediate any
Environmental Defect under Section 6.1(b), if any Environmental Defect timely
asserted by Buyer in accordance with Section 6.1(a) is not waived in writing by
Buyer or Remediated, then in connection with the Closing (unless, as of the
Closing, the Parties are in disagreement with respect to the existence of such
Environmental Defect or any associated Remediation Amount, in each of which case
the applicable Environmental Dispute shall, unless otherwise agreed by the
Parties, be addressed pursuant to Section 6.1(f)) Seller shall, at its sole
option and discretion, elect one or more of the following remedies for such
Environmental Defect:
(i)    Seller will convey the entirety of the Environmental Defect Property that
is subject to such Environmental Defect, together with all associated Assets, at
Closing, to Buyer and make an accompanying reduction to the Purchase Price by
the Remediation Amount for such Environmental Defect agreed to by the Parties or
otherwise determined pursuant to Section 6.1(f); or
(ii)    if the Remediation Amount of the Environmental Defect Property equals or
exceeds the Allocated Value of the applicable Environmental Defect Property,
Seller will retain the entirety of the Environmental Defect Property that is
subject to such Environmental Defect, together with all associated Assets (in
which case, such Assets shall become Excluded Assets hereunder), and reduce the
Purchase Price by an amount equal to the Allocated Value of such Environmental
Defect Property and such associated Assets.
If the option set forth in clause (i) above is selected, subject always to
Seller’s right to Remediate any Environmental Defect under Section 6.1(b), (1)
Buyer shall be deemed to have assumed responsibility for all costs and expenses
attributable to the Remediation of the applicable Environmental Defect and all
Liabilities (net to the Assets) with respect thereto, and (2) Buyer’s
obligations with respect to the foregoing shall be deemed to constitute Assumed
Obligations. If Seller elects to attempt to Remediate any Environmental Defect
pursuant to Section 6.1(b), Seller shall use commercially reasonable efforts to
complete such Remediation in a manner which is in compliance with the
requirements of Environmental Laws in a timely fashion for the type of
Remediation that Seller elects to undertake and at the Closing the Parties shall
execute and deliver a mutually agreeable site access and indemnity agreement
affording Seller with reasonable access to the relevant Assets to conduct such
Remediation. Seller will be deemed to have adequately completed the Remediation
required in the immediately preceding sentence (A) upon receipt of a certificate
or approval from the applicable Governmental Authority that the Remediation has
been implemented to the extent necessary to cure the Environmental Defect and
comply with existing Laws or (B) subject to Buyer’s reasonable agreement, upon
receipt of a certificate from a licensed professional engineer that the
Remediation has been implemented to the extent necessary to cure the
Environmental Defect and comply with existing Laws.
(d)    Exclusive Remedy. Subject to Seller’s representations and warranties in
Section 7.20 and in the certificate delivered by Seller at Closing, and without
limiting Buyer’s

lix
US-DOCS\112434093.5

--------------------------------------------------------------------------------

conditions to Closing set forth in Article X (including as set forth in Section
10.4), the provisions of Section 6.1(c) shall be the exclusive right and remedy
of Buyer with respect to any Environmental Defect or other environmental matter.
(e)    Environmental Threshold and Deductible. Notwithstanding anything herein
to the contrary, (i) in no event shall there be any adjustments to the Purchase
Price or any other remedy provided by Seller hereunder for any individual
Environmental Defect for which the Remediation Amount applicable thereto does
not exceed $50,000 (the “Individual Environmental Defect Threshold”) and (ii) in
no event shall there be any adjustments to the Purchase Price or any other
remedy provided by Seller hereunder for any Environmental Defect for which the
Remediation Amount applicable thereto exceeds the Individual Environmental
Defect Threshold unless and until (A) the sum of (1) the Remediation Amounts of
all such Environmental Defects that exceed the Individual Environmental Defect
Threshold, in the aggregate (excluding any Remediation Amounts attributable to
(v) Environmental Defects Remediated by Seller, and (w) Environmental Defect
Properties that are retained by Seller pursuant to Section 6.1(c)(ii)), plus (2)
the Title Defect Amounts (net of any offsetting Title Benefit Amounts in
accordance with Section 5.2(e)) of all Title Defects that exceed the Individual
Title Defect Threshold, in the aggregate (excluding any Title Defect Amounts
attributable to (x) Title Defects cured by Seller, and (y) Title Defect
Properties retained by Seller pursuant to Section 5.2(d)(ii)), exceeds (B) the
Aggregate Deductible, in which case Buyer shall be entitled to remedies for such
Environmental Defects only to the extent that the Remediation Amounts with
respect thereto are in excess of such Aggregate Deductible.
(f)    Environmental Dispute Resolution. Seller and Buyer shall attempt in good
faith to agree on all Environmental Defects and Remediation Amounts (any dispute
with respect to the foregoing matters, collectively “Environmental Disputes”)
prior to the Closing or, if the applicable Environmental Dispute relates to any
Environmental Defect Property for which Seller has attempted to Remediate the
alleged Environmental Defect(s) following Closing and prior to the expiration of
the Cure Period, then prior to the date that is ten Business Days following the
expiration of the Cure Period. If Seller and Buyer are unable to agree within
the above applicable time period, the Environmental Disputes shall be
exclusively and finally resolved pursuant to this Section 6.1(f). Nothing herein
shall operate to cause Closing to be delayed on account of any arbitration
conducted pursuant to this Section 6.1(f) with respect to any Environmental
Defect properly asserted by Buyer prior to the Defect Claim Date, and to the
extent any adjustments are not agreed upon by the Parties as of the Closing,
unless Seller has elected to retain the applicable Environmental Defect Property
pursuant to (and subject to the limitations in) Section 6.1(c)(ii), the affected
Environmental Defect Property shall be assigned to Buyer at Closing and the
Purchase Price shall be reduced by an amount equal to the Remediation Amount
applicable for such Environmental Defect, which amount (including any disputed
amounts) shall be paid into the Escrow Account at Closing and remain therein
until such dispute is resolved pursuant to this Section 6.1(f). Any
Environmental Disputes shall be submitted to an arbitrator, with at least ten
years’ experience in environmental matters involving oil and gas properties
including properties in the regional area in which the Subject Properties are
located (the “Environmental Arbitrator”). If the Parties are unable to agree on
the selection of the Environmental Arbitrator within ten Business Days of the
Parties agreeing to submit an Environmental Dispute to the Environmental
Arbitrator for determination or, in the case where the Parties have not so
agreed, within ten Business Days of the non-submitting Party receiving

lx
US-DOCS\112434093.5

--------------------------------------------------------------------------------

written notice from the submitting Party stating that such Party has elected to
submit an Environmental Dispute to arbitration in accordance with this Section
6.1(f), the AAA shall make the necessary appointment (which Environmental
Arbitrator shall not have worked as an employee, outside counsel or as a
consultant for any Party or its Affiliates during the five year period preceding
the arbitration or have any financial interest in the dispute). The place of
arbitration shall be Houston, Texas, and the arbitration shall be conducted in
accordance with the AAA Rules, to the extent such rules do not conflict with the
terms of this Section 6.1. The Parties, within ten days after the Environmental
Arbitrator is appointed, shall submit written summaries of their positions
regarding each Environmental Dispute. The Parties shall instruct the
Environmental Arbitrator to make a determination, choosing either Seller’s
position or Buyer’s position with respect to each Environmental Dispute,
whichever the Environmental Arbitrator determines complies more closely to the
terms of this Agreement, within 20 Business Days after the submission of the
Parties’ summaries of the Environmental Disputes to the Environmental
Arbitrator, and such determination shall be final and binding upon both Parties,
without right of appeal. The costs of the Environmental Arbitrator shall be
borne one-half by Seller and one-half by Buyer. In making its determination, the
Environmental Arbitrator shall be bound by the terms of this Article VI and,
subject to the foregoing, may consider such other matters as in the opinion of
the Environmental Arbitrators are necessary to make a proper determination. The
Environmental Arbitrator shall act for the limited purpose of determining the
specific Environmental Disputes submitted by either Party and may not award
damages, interest or penalties to either Party with respect to any Environmental
Dispute. Seller and Buyer shall each bear its own legal fees and other costs of
presenting its case to the Environmental Arbitrator. Within two Business Days
after the Environmental Arbitrator delivers written notice to Buyer and Seller
of its award with respect to an Environmental Dispute, and subject to
Section 6.1(e), Parties shall execute and deliver a joint instruction to Escrow
Agent requiring Escrow Agent to disburse to each Party the funds in the Escrow
Account to which such Party is entitled in respect of the applicable
Environmental Dispute.

6.2    NORM, Wastes and Other Substances. Buyer acknowledges that the Assets
have been used for exploration, development and production of oil and gas and
that there may be petroleum, produced water, wastes or other substances or
materials located in, on or under the Assets or associated with the Assets.
Equipment and sites included in the Assets may contain asbestos, NORM or other
Hazardous Materials. 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 the Assets or included in the Assets may contain NORM and
other wastes or Hazardous Materials. NORM containing material or other wastes or
Hazardous Materials may have come in contact with various environmental media,
including water, soils or sediment. Special procedures may be required for the
assessment, Remediation, removal, transportation or disposal of environmental
media, wastes, asbestos, NORM and other Hazardous Materials from the Assets.
Notwithstanding anything herein to the contrary, Buyer shall not be permitted to
claim any Environmental Defect on the account of the presence of NORM on the
Assets and the properties underlying the Assets.

if applicable, Buyer’s operating Affiliate) (a) will have lease bonds, area-wide

pay on a timely basis all costs required to be paid by Buyer under this

the effect of bankruptcy, insolvency, reorganization, moratorium and similar
Laws affecting the rights of creditors generally.

rely on its own independent investigation and evaluation of the Assets, which
investigation and evaluation was done by Buyer and its own legal, Tax, economic,
environmental, engineering, geological and geophysical advisors. In entering
into this Agreement, Buyer acknowledges that it has relied solely upon the
aforementioned investigation and evaluation and not on any factual
representations or opinions of Seller or any representatives or consultants or
advisors engaged by or otherwise purporting to represent Seller or any Affiliate
of Seller (except the specific representations and warranties of Seller set
forth in Article VII and the limited special warranty of Defensible Title in the
Assignment). Buyer hereby acknowledges that, other than the representations and
warranties made in Article VII and the limited special warranty of Defensible

8.11    Accredited Investor. Buyer is an accredited investor, as such term is
defined in Regulation D of the Securities Act of 1933, as amended, and will
acquire the Assets for its own account and not with a view to a sale or
distribution thereof in violation of the Securities Act of 1933, as amended, and
the rules and regulations thereunder, any applicable state blue sky Laws or any
other applicable securities Laws.

lxxii
US-DOCS\112434093.5

--------------------------------------------------------------------------------

For the avoidance of doubt, the pendency of the Chapter 11 Case and any actions
required to be taken by Seller pursuant to an order of the Bankruptcy Court in
connection with the Chapter 11 Case shall in no way be deemed a breach of this
Section 9.1(b).
(c)    Without expanding any obligations which Seller may have to Buyer, it is
expressly agreed that Seller shall never have any liability to Buyer with
respect to any breach or failure of Section 9.1(a)(i) greater than that which it
might have as the operator to a non-operator under the applicable operating
agreement (or, in the absence of such an agreement, under the AAPL 610 (1989
Revision) form Operating Agreement), IT BEING RECOGNIZED THAT, UNDER SUCH
AGREEMENTS AND SUCH FORM, THE OPERATOR IS NOT RESPONSIBLE FOR ITS OWN
NEGLIGENCE, AND HAS NO RESPONSIBILITY OTHER THAN FOR GROSS NEGLIGENCE OR WILLFUL

(d)    Buyer acknowledges that Seller owns undivided interests in certain of the
Assets with respect to which it is not the operator, and Buyer agrees that the
acts or omissions of the other working interest owners (including the operators)
who are not Seller or any Affiliates of Seller shall not constitute a breach of
the provisions of this Section 9.1, nor shall any action required by a vote of
working interest owners constitute such a breach so long as Seller has voted its
interest in a manner that complies with the provisions of this Section 9.1.

9.2    Bonds. Buyer acknowledges that none of Asset Credit Support will be
transferred to Buyer. At or prior to Closing, Buyer shall obtain, or cause to be
obtained in the name of Buyer (or, if applicable, Buyer’s operating Affiliate),
replacements for such Asset Credit Support (in each case, insofar and only to
the extent necessary under an Assigned Contract or as required under applicable
Law) to the extent such replacements are necessary (i) to consummate the
transactions contemplated by this Agreement and (ii) to permit the cancellation
of such Asset Credit Support posted by Seller or any of its Affiliates. In
addition, at or prior to Closing, Buyer shall deliver to Seller evidence of
Buyer’s posting of bonds or other security necessary to replace the Asset Credit
Support listed on Schedule 7.14, in each case, insofar as and only to the extent
necessary under an Assigned Contract or as required under applicable Law. At or
prior to Closing, Buyer shall use commercially reasonable efforts to cooperate
with Seller and cause the cancellation of such Asset Credit Support, including
discussions with OneOk to ensure the return of Asset Credit Support provided by
or on behalf of Seller or its Affiliates under any OneOk Contract.
Notwithstanding anything to the contrary herein, in no event shall the OneOk
Contract be an Assigned Contract unless any Asset Credit Support provided by or
on behalf of any Seller or Affiliate of Seller in connection with such
Applicable Contract is returned to Seller at or prior to Closing.

9.3    Notifications. If, prior to Closing, either Seller or Buyer obtains
Knowledge that the other Party has breached a representation, warranty,
covenant, obligation or other agreement under this Agreement, then Seller or
Buyer, as applicable, shall promptly inform such other Party of such breach so
that such other Party may attempt to remedy or cure such breach prior to
Closing; provided that, such notice shall not be deemed and shall not constitute
a waiver of any claim or recourse against the other Party or its Affiliates
(including any claim for indemnity) with respect to any breach by such other
Party of such other Party’s representations, warranties,

lxxiii
US-DOCS\112434093.5

covenants, obligations or other agreements, and shall not in any way preclude
the right of any Party to rely on the representations and warranties of the
other Party given in this Agreement or in the certificates delivered by such
Party at Closing pursuant to this Agreement.

9.4    Financing.
(a)    On or before January 15, 2020 (the “Commitment Deadline”) Buyer shall
furnish to Seller an accurate and complete copy of the Commitment in an amount
equal to at least $310,000,000 (the “Required Amounts”), and the executed fee
letters, if applicable (the “Fee Letters”, together with the Commitment, the
“Commitment Documentation”) executed in connection therewith (provided, that
provisions in the Fee Letter related to fees or “flex” terms may be redacted
(none of which redacted provisions could reasonably be expected to adversely
affect the conditionality, availability, the aggregate amount of the financing
contemplated thereby or delay the availability of such financing). The
obligations of the financing sources to fund the commitments under the
Commitment shall not be subject to any conditions or other contingencies related
to the funding of the full Required Amounts (including any “flex” provisions set
forth in the Commitment Documentation) other than as set forth in the Commitment
Documentation. Other than as explicitly set forth in the Commitment
Documentation, the Commitment Documentation, when delivered, will constitute the
entire and complete agreement between the parties thereto with respect to the
Financing (subject to the redaction of provisions in the Fee Letter related to
fees or “flex” terms permitted above). Notwithstanding the foregoing, Buyer’s
ability to consummate the transactions contemplated hereby is not contingent
upon its ability to secure any financing (including the financing contemplated
by the Commitment) or to complete any public or private placement of securities
prior to or upon Closing.
(b)    Upon delivery of the Commitment Documentation to Seller:
(i)    Buyer shall use its reasonable best efforts to obtain the financing under
the Commitment required to effect the transactions contemplated by this
Agreement as promptly as practicable, including, without limitation, (1) using
reasonable best efforts to (A) maintain in effect the Commitment Documentation,
(B) satisfy on a timely basis all terms, covenants and conditions set forth in
the Commitment, (C) enter into definitive agreements with respect thereto on the
terms and conditions contemplated by the Commitment Documentation and (D)
consummate such financing at or prior to Closing and (2) seeking to enforce its
rights under the Commitment.
(ii)    Upon Seller’s reasonable request, Buyer shall keep Seller reasonably
informed with respect to all material activity concerning the status of the
financing contemplated by the Commitment and shall give Seller prompt notice of
any adverse change with respect to such financing. Without limiting the
foregoing, Buyer agrees to notify Seller promptly, if at any time prior to the
Closing Date (1) any Commitment shall expire or be terminated for any reason,
(2) any financing source that is a party to any Commitment notifies Buyer that
such source no longer intends to provide financing to Buyer on the terms set
forth therein, or (3) for any reason Buyer no longer believes in good faith that
it will be able to obtain all or any portion of the financing contemplated by
the Commitment on the terms described therein.

lxxiv
US-DOCS\112434093.5

--------------------------------------------------------------------------------

(iii)    Buyer shall not permit any amendment, supplement or modification to be
made to, or any waiver of any provision under, the Commitment Documentation if
such amendment, supplement, modification or waiver, (A) reduces (or could
reasonably be expected to have the effect of reducing) the aggregate amount of
the financing, or (B) imposes new or additional conditions or otherwise expands,
amends or modifies any of the conditions to the Commitment, or imposes new or
additional conditions or otherwise expands, amends or modifies any other
provision of the Commitment Documentation, in the case of clause (B), in a
manner that would (x) reasonably be expected to prevent or make less likely the
funding of the Commitment in an amount necessary to fund the Required Amounts on
the Closing Date or (y) adversely impact the ability of Buyer to enforce its
rights against other parties to the Commitment Documentation with respect
thereto (provided that, subject to compliance with the other provisions of this
Section 9.4, Buyer may amend the Commitment Documentation to add additional
lenders, arrangers, bookrunners and agents). Buyer shall promptly deliver to
Seller copies of any amendment, supplement, waiver, consent, modification or
replacement in respect of the Commitment Documentation (other than an amendment
to add additional lenders, arrangers, bookrunners and agents). Buyer shall not
agree to the withdrawal, termination, repudiation, reduction or rescission of
any commitment in respect of the Commitment, and shall not release or consent to
the termination of the obligations of the financing sources under the
Commitment, in each case, without the prior written consent of Seller, to the
extent such withdrawal, termination, repudiation, reduction or rescission is in
an amount such that the net proceeds of the Commitment would not be in an amount
sufficient to fund the Required Amounts at Closing after giving effect thereto.
Buyer shall promptly deliver to Seller copies of any such amendment,
modification or replacement. For purposes of this Agreement, (i) references to
“Commitment” and “Commitment Documentation” shall include the financing
contemplated by the Commitment Documentation as permitted to be amended,
modified, supplemented or replaced by this Section 9.4.
(iv)    If any portion of the financing becomes unavailable in the amount
contemplated in any Commitment or any Commitment shall be terminated or modified
in a manner materially adverse to Buyer for any reason, Buyer shall use its
reasonable best efforts to obtain alternative financing from alternative sources
in an amount sufficient to enable Buyer to perform its obligations under, and to
consummate the transactions contemplated by, this Agreement and to obtain, and,
if obtained, will provide Seller with a copy of, a new financing commitment that
provides for at least the same amount of financing as the Commitment as
originally issued, to the extent needed to fund the Required Amounts, and on
terms and conditions (including termination rights and funding conditions) not
materially less favorable to Buyer than those included in the Commitment (the
“New Commitment”). To the extent applicable, Buyer shall use reasonable best
efforts to obtain the alternative financing as set forth in the New Commitment
as promptly as practicable, including, without limitation, (1) using reasonable
best efforts to (A) satisfy on a timely basis all terms, covenants and
conditions set forth in the New Commitment, (B) enter into definitive agreements
with respect thereto on the terms and conditions contemplated by the New
Commitment and (C) consummate such financing at or prior to Closing and (2)
seeking to enforce its rights under the New Commitment (including through
litigation). In the event

lxxv
US-DOCS\112434093.5

--------------------------------------------------------------------------------

alternative financing is obtained and a New Commitment is entered into,
references in this Agreement to the Commitment shall be deemed to refer to the
New Commitment, and references in this Agreement to the financing under the
Commitment shall be deemed to refer to the alternative financing under the New
Commitment, in each case as applicable.
(c)    Prior to the Closing Date, Seller shall use, and shall cause each of its
controlled Affiliates to use, and shall use reasonable best efforts to have each
of its and its controlled Affiliates’ respective directors, officers and
advisors to use, in each case, their respective reasonable best efforts to
provide to Buyer, all cooperation reasonably necessary and customary in
connection with the arrangement of the Commitment (provided that such requested
cooperation does not unreasonably interfere with the ongoing operations of
Seller or its controlled Affiliates), which reasonable best efforts shall
include (i) upon reasonable notice, and at reasonable times and locations to be
mutually agreed, causing the management teams of Seller and its controlled
Affiliates with appropriate seniority and expertise and external auditors to
participate in a reasonable number of meetings, drafting sessions,
presentations, road shows, and rating agency and due diligence sessions, (ii)
assisting with the preparation of (A) offering documents, private placement

financial statements which are necessary to satisfy the conditions set forth in
the Commitment Documentation promptly after such financial statements become
available, (v) assisting with the preparation of any pledge and security
documents, guarantees, other definitive financing documents, or other related
certificates or documents as may be reasonably requested by Buyer and otherwise
facilitating the pledging of collateral to the extent required at Closing by the
Commitment Documentation (including cooperation in connection with the pay-off
at Closing of existing Indebtedness and the release, following such repayment,
of related Liens and termination, following such repayment, of security
interests (including delivering prepayment or termination notices as required),
and (vi) to the extent requested at least ten Business Days prior to the Closing
Date, providing, at least three Business Days prior to the Closing Date, all
documentation with respect to Seller and its controlled Affiliates required by
applicable “know your customer” and anti-money laundering applicable laws,
including the USA PATRIOT Act, to the extent requested in writing at least ten
Business Days prior to the Closing Date; provided, however, that Seller shall
not be required to provide, or cause its controlled Affiliates to provide,
cooperation under this Section 9.4 that: (A) unreasonably interferes with the
ongoing business of Seller or its controlled Affiliates; (B) causes any
covenant, representation or warranty in this Agreement to be breached or
otherwise causes the breach of this Agreement or any Contract to which any of
Seller or its controlled Affiliates is a party, in each case, in a manner that
would cause any closing condition set forth herein to fail to be satisfied; (C)
requires Seller or its controlled Affiliates to incur any liability, cost or
expense (including, without limitation, any commitment fees and expense
reimbursement) in connection with the Commitment (other than the authorization
letters and management representation letters) prior to, or that are not
conditioned upon, the Closing, provided that Seller or its controlled Affiliates
shall be reimbursed by Buyer for any such liability, cost or expense so
incurred; (D) requires Seller or its controlled Affiliates or their respective
directors, officers, managers or employees (other than execution and delivery
into escrow by those officers that will act in a similar capacity after the
Closing) to execute, deliver or enter into, or perform any agreement, document,

connection with the Commitment; provided that such logos are used solely in a
manner that is not intended to or reasonably likely to harm or disparage Seller
or any of its controlled Affiliates or the reputation or goodwill of Seller or
any of its controlled Affiliates.

9.5    Equitable and Other Remedies. The Parties agree that damages may not be a
sufficient remedy to any breach of the provisions of Section 4.2, Section 9.6,
Section 14.3, Section 16.6 or Section 16.8 of this Agreement and the
non-breaching Party may be irreparably and immediately harmed if any of such
provisions of this Agreement are not performed by the other Party or its

Party may have, to obtain injunctive relief, without the posting of any bond and

does not covenant or warrant that Buyer (or, if applicable, Buyer’s operating

(j)    Without limiting the requirements of Section 9.8(a) through (i), from and
after the Execution Date and through the Closing or the termination of this
Agreement in accordance with Section 14.1, each of the Seller Parties and AMR
agrees to:
(i)    use commercially reasonable efforts to obtain any and all required
regulatory and/or Third Party approvals for the Transactions;
(ii)    upon reasonable request of Buyer, inform the advisors to Buyer as to:
(A) the material business and financial (including liquidity) performance of the
Seller Parties, but only to the extent Seller prepares reports or materials
regarding such items in the ordinary course of business; (B) the status and
progress of the Transactions, including progress in relation to the negotiations
of the definitive documents; and (C) the status of obtaining any necessary or
desirable authorizations (including any consents) from each secured lender, any
competent judicial body, governmental authority, banking, taxation, supervisory,

insolvency proceedings, legal suit for payment of debt or securement of security

(iv)    use good faith efforts to seek additional support for the Transaction
from their other material stakeholders to the extent reasonably prudent and, to
the extent the Seller Parties receive such support, to notify Buyer of such
support and documentation thereof.
(k)    Nothing in this Agreement, including this Section 9.8, shall require any
director or officer of any Seller Party or AMR to violate their fiduciary duties
to such Seller Party or AMR, as applicable. No action or inaction on the part of
any director or officer of any Seller Party or AMR that such director or officer
reasonably believes is required by their fiduciary duties to such Seller Party
or AMR (as applicable) shall be limited or precluded by this Agreement;
provided, however, that no such action or inaction shall be deemed to prevent
Buyer from exercising any termination rights it may have hereunder as a result
of such action or inaction.
(l)    If an Auction is conducted and Seller does not choose Buyer as the
Successful Bidder, but instead chooses Buyer as the Backup Bidder, Buyer will
serve as the Backup Bidder. If Buyer is chosen as the Backup Bidder, Buyer will
be required to keep its bid to consummate the transactions contemplated by this
Agreement on the terms and conditions set forth in this Agreement (as may be
amended with Buyer’s written consent prior to or at the Auction) open and
irrevocable until the Closing of the sale of the Assets to the Successful
Bidder; provided that Buyer shall not be required to serve as Backup Bidder
unless (i) the Successful Bid (as defined in the Bidding Procedures Order)
contemplates the acquisition of all or substantially all of the assets of both
Seller and the KFM Sellers, or (ii) Buyer is also the “Successful Bidder” or
“Backup Bidder” (each as defined in the KFM Agreement) for all or substantially
all of the assets of the KFM Sellers. If the

lxxx
US-DOCS\112434093.5

--------------------------------------------------------------------------------

agreement with the Successful Bidder is terminated prior to Closing, Buyer will
be deemed to be the Successful Bidder and will forthwith consummate the
transactions contemplated by this Agreement on the terms and conditions set
forth in this Agreement (as the same may be amended with Buyer’s written consent
prior to or at the Auction). For the avoidance of doubt, Buyer shall have no
obligation to consummate the transactions contemplated by this Agreement set
forth in this Agreement if the transactions under the KFM Agreement fail to
close contemporaneously with, or prior to, the Closing.
(m)    Seller shall apply the Deposit to the Purchase Price or return the
Deposit to Buyer (as applicable) in accordance with the Bidding Procedures Order
and Bid Procedures (including the section of the Bid Procedures titled “Return
of Good Faith Deposit”). Any instructions provided by Seller to Escrow Agent in
respect of the Deposit shall be consistent with the Bidding Procedures Order and
Bid Procedures Order, and this Section 9.8(m), in all respects.

9.9    Certain Litigation Matters. Within ten Business Days after the Execution
Date, Buyer shall notify Seller in writing which of those matters identified on
Schedule 7.6 it desires to be Assumed Obligations, and which of those matters it
desires to be Excluded Liabilities. Failure of Buyer to provide such notice
within such time period shall be deemed an election to cause all such matters to
be Excluded Liabilities.

9.10    Accounting Services.
From and after the Closing Date until the end of the calendar month in which the
sixty (60) day anniversary of the Closing Date occurs, Seller shall continue to
perform the services set forth on Exhibit E (the “Accounting Services”) for the
purposes of performing the Accounting Services for production month February
2020. Seller shall perform the Accounting Services with the degree of care,
skill and diligence with which it has performed similar services for the
Properties and the related operations prior to the Closing Date. The quality of
Accounting Services provided by Seller is not required to be higher than the
quality of the same or similar services that Seller has historically provided
with respect to the Properties. In no event shall Seller have any liability to
Buyer hereunder in connection with the performance of the Accounting Services
except to the extent of the gross negligence or willful misconduct of Seller
(including any employee of Seller performing any of the Accounting Services).
Between the Execution Date and the Auction, the Parties shall cooperate in good
faith to agree a fixed cost or other pricing mechanism for the provision of such
Accounting Services, which fixed cost or other pricing mechanism is to be based
on the estimated direct fully burdened expenses to be incurred with respect to
the provision of such Accounting Services. In the event the Parties are unable
to agree to such a fixed cost or other pricing mechanism prior to Closing, after
Closing, Buyer shall reimburse Seller for all direct fully burdened expenses
incurred by Seller in connection with the provision of the Accounting Services;
provided that Seller shall inform Buyer when Seller has incurred cumulative
direct fully burdened expenses in connection with the performance of the
Accounting Services in amounts totaling $250,000, $500,000, $750,000, and
$1,000,000, and in no event shall Buyer be obligated to pay Seller more than
$1,000,000 for the provision of such Accounting Services. Seller shall use
reasonable efforts to make the employees who will provide the Accounting
Services hereunder reasonably available to Buyer throughout the Term; provided
that Seller will not be obligated to replace any such employee who resigns or

lxxxi

--------------------------------------------------------------------------------

otherwise does not continue to provide services to Buyer or is otherwise
unavailable due to disability, illness or otherwise, in which case Seller shall

Services. Buyer may at any time, upon one Business Day prior written notice to
Seller, terminate all or any portion of the Accounting Services.

of 1980, as amended, breaches of statutory or implied warranties, nuisance or
other tort actions, rights to punitive damages, common Law rights of
contribution, and rights under insurance maintained by Seller or any of its
Affiliates.

13.5    Indemnification Procedures. All claims for indemnification under
Section 4.1(d), Section 9.2 and Section 13.2 shall be asserted and resolved as
follows:
(a)    For purposes of this Agreement, the term “Indemnifying Party” means
Buyer, and the term “Indemnified Party” when used in connection with particular
Liabilities shall mean Seller or the Person(s) having the right to be
indemnified with respect to such Liabilities by another Party pursuant to
Section 4.1(d), Section 9.2 or Section 13.2.
(b)    To make claim for indemnification under Section 4.1(d), Section 9.2,
Section 13.2 or Section 13.3, an Indemnified Party shall notify the Indemnifying
Party of its claim under this Section 13.5, including the specific details of
and specific basis under this Agreement for its claim (the “Claim Notice”). In
the event that the claim for indemnification is based upon a claim by a Third
Party against the Indemnified Party (a “Third Party Claim”), the Indemnified
Party shall

xc
US-DOCS\112434093.5

--------------------------------------------------------------------------------

provide its Claim Notice promptly after the Indemnified Party has Knowledge of
the Third Party Claim and shall enclose a copy of all papers (if any) served
with respect to the Third Party Claim; provided that the failure of any
Indemnified Party to give notice of a Third Party Claim as provided in this
Section 13.5(b) shall not relieve the Indemnifying Party of its obligations
under Section 4.1(d), Section 9.2, Section 13.2 or Section 13.3 (as applicable)
except to the extent such failure results in insufficient time being available
to permit the Indemnifying Party to effectively defend against the Third Party
Claim or otherwise materially prejudices the Indemnifying Party’s ability to
defend against the Third Party Claim. In the event that the claim for
indemnification is based upon an inaccuracy or breach of a representation,
warranty, covenant, obligations or agreement, the Claim Notice shall specify the
representation, warranty, covenant, obligation or agreement that was inaccurate
or breached.
(c)    In the case of a claim for indemnification based upon a Third Party
Claim, the Indemnifying Party shall have 30 days from its receipt of the Claim
Notice to notify the Indemnified Party whether it admits or denies its liability
to defend the Indemnified Party against such Third Party Claim at the sole cost
and expense of the Indemnifying Party. The Indemnified Party is authorized,
prior to and during such 30 day period, at the expense of the Indemnifying
Party, to file any motion, answer or other pleading that it shall deem necessary
or appropriate to protect its interests or those of the Indemnifying Party and
that is not prejudicial to the Indemnifying Party. Failure of an Indemnifying
Party to admit its liability to defend an Indemnified Party within such 30 day
period shall be deemed a denial of liability to so defend such Indemnified
Party.
(d)    If the Indemnifying Party admits its liability to defend the Indemnified
Party against a Third Party Claim, it shall have the right and obligation to
diligently defend, at its sole cost and expense, such Third Party Claim. The
Indemnifying Party shall have full control of such defense and proceedings,
including any compromise or settlement thereof. If requested by the Indemnifying
Party, the Indemnified Party shall cooperate in contesting any Third Party Claim
that the Indemnifying Party elects to contest. The Indemnified Party may
participate in, at its own expense, but subject to the Indemnifying Party’s full
control of, any defense or settlement of any Third Party Claim controlled by the
Indemnifying Party pursuant to this Section 13.5(d); provided, however, that the
Indemnified Party shall not be required to bring any counterclaim or cross
complaint against any Person. An Indemnifying Party shall not, without the prior
written consent of the Indemnified Party, (i) settle any Third Party Claim or
consent to the entry of any judgment or order with respect thereto which does
not result in a final resolution of the Indemnified Party’s Liability in respect
of such Third Party Claim (including, in the case of a settlement, an
unconditional written release of the Indemnified Party from all Liability in
respect of such Third Party Claim), or (ii) settle any Third Party Claim or
consent to the entry of any judgment or order with respect thereto in any manner
that may materially and adversely affect the Indemnified Party (other than as a
result of money damages covered by the indemnity).
(e)    If the Indemnifying Party does not admit its liability or admits its
liability to defend the Indemnified Party against the Third Party Claim, but
fails to diligently prosecute or settle such Third Party Claim, then the
Indemnified Party shall have the right to defend against the Third Party Claim
at the sole cost and expense of the Indemnifying Party, with counsel of its
choosing, subject to the right of the Indemnifying Party to admit its liability
and assume the defense of the

xci
US-DOCS\112434093.5

--------------------------------------------------------------------------------

Third Party Claim at any time prior to settlement or final determination
thereof. If the Indemnifying Party has not yet admitted its liability to defend
the Indemnified Party against the Third Party Claim, the Indemnified Party shall
send written notice to the Indemnifying Party of any proposed settlement, unless
the proposed settlement is solely for money damages and results in a final
resolution, and the Indemnifying Party shall have the option for ten days
following receipt of such notice to (i) admit in writing its liability to
indemnify the Indemnified Party from and against the liability and consent to
such settlement, (ii) if liability is so admitted, reject, in its reasonable
judgment, the proposed settlement, or (iii) deny liability. Any failure to
respond to such notice by the Indemnified Party within such ten day-period shall
be deemed to be an election under subsection (i) above.
(f)    In the case of a claim for indemnification not based upon a Third Party
Claim, the Indemnifying Party shall have 30 days from its receipt of the Claim
Notice to (i) cure the Liabilities complained of, (ii) admit its liability for
such Liability or (iii) dispute the claim for such Liabilities. If the
Indemnifying Party does not notify the Indemnified Party within such 30 day
period that it has cured the Liabilities or that it disputes the claim for such
Liabilities, the Indemnifying Party shall be deemed to have disputed the claim
for such Liabilities.

13.6    Survival.
(a)    The representations and warranties of Seller in Article VII and in the
certificate delivered pursuant to Section 10.5 shall terminate at the Closing.
All covenants, obligations and agreements of Seller (or, if applicable AMR) in
this Agreement (i) that are required to be performed at or prior to Closing
shall terminate at Closing and (ii) that cannot be performed until after the
Closing shall survive until fully performed. The limited special warranty of
Defensible Title in the Instruments of Conveyance shall survive Closing for six
months.
(b)    Subject to Section 13.6(a) and except as set forth in Section 13.6(c),
the remainder of this Agreement shall survive the Closing without time limit.
Representations, warranties, covenants, obligations and agreements shall be of
no further force and effect after the date of their expiration as set forth in
Section 13.6(a) or Section 13.6(c); provided that there shall be no termination
of any bona fide claim asserted pursuant to this Agreement with respect to such
a representation, warranty, covenant, obligation or agreement prior to its
expiration date.
(c)    The indemnities in Section 13.2(a) and Section 13.2(b) shall terminate as
of the termination date of each respective representation, warranty, covenant or
agreement that is subject to indemnification. Buyer’s indemnities set forth in
Section 13.2(c), and Section 13.2(d) shall survive the Closing without time
limit. Notwithstanding the foregoing, there shall be no termination of any bona
fide claim asserted pursuant to the indemnities in Section 13.2 prior to the
date of termination for such indemnity.

13.7    Non-Compensatory Damages. WITHOUT LIMITING SECTION 9.5, NOTWITHSTANDING
ANYTHING CONTAINED IN THIS AGREEMENT TO THE CONTRARY, NONE OF THE BUYER PARTIES
NOR THE SELLER INDEMNIFIED PARTIES SHALL BE ENTITLED TO RECOVER FROM THE OTHER
PARTY OR SUCH OTHER PARTY’S AFFILIATES ANY INDIRECT, CONSEQUENTIAL, SPECIAL,
PUNITIVE, INCIDENTAL, SPECULATIVE OR EXEMPLARY DAMAGES OR DAMAGES

xcii
US-DOCS\112434093.5

--------------------------------------------------------------------------------

FOR LOST PROFITS OR LOSS OF BUSINESS OPPORTUNITY OF ANY KIND ARISING UNDER,
RELATED TO OR IN CONNECTION WITH THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED
HEREBY, EXCEPT TO THE EXTENT ANY SUCH PERSON SUFFERS SUCH DAMAGES (INCLUDING
COSTS OF DEFENSE AND REASONABLE ATTORNEYS’ FEES INCURRED IN CONNECTION WITH THE
DEFENSE OF SUCH DAMAGES) TO A THIRD PARTY, WHICH DAMAGES (INCLUDING COSTS OF
DEFENSE AND REASONABLE ATTORNEYS’ FEES INCURRED IN CONNECTION WITH THE DEFENSE
OF SUCH DAMAGES) SHALL NOT BE EXCLUDED BY THIS PROVISION AS TO RECOVERY
HEREUNDER. SUBJECT TO THE PRECEDING SENTENCE AND SECTION 9.5, AND
NOTWITHSTANDING ANYTHING CONTAINED IN THIS AGREEMENT TO THE CONTRARY, EACH OF
SELLER, ON BEHALF OF ITSELF AND THE SELLER INDEMNIFIED PARTIES, AND BUYER, ON
BEHALF OF ITSELF AND THE BUYER PARTIES, WAIVES ANY RIGHT TO RECOVER INDIRECT,
CONSEQUENTIAL, SPECIAL, PUNITIVE, INCIDENTAL, SPECULATIVE AND EXEMPLARY DAMAGES,
INCLUDING DAMAGES FOR LOST PROFITS OR LOSS OF BUSINESS OPPORTUNITY OF ANY KIND,
ARISING IN CONNECTION WITH OR WITH RESPECT TO THIS AGREEMENT OR THE TRANSACTIONS
CONTEMPLATED HEREBY. THIS SECTION 13.7 SHALL NOT RESTRICT ANY PARTY’S RIGHT TO
OBTAIN SPECIFIC PERFORMANCE OR ANY INJUNCTION IN ACCORDANCE WITH THE TERMS AND
CONDITIONS OF THIS AGREEMENT.

13.8    Waiver or Right to Rescission. Seller and Buyer acknowledge that,
subject to any rights the Parties may have hereunder to seek and obtain specific
performance or other express injunctive remedies, following Closing, the payment
of money, as limited by the terms of this Agreement, shall be adequate
compensation for breach of any representation, warranty, covenant, obligation or
agreement contained herein or for any other claim arising in connection with or
with respect to the transactions contemplated by this Agreement. As such, Buyer
and Seller waive any right to rescind this Agreement or any of the transactions
contemplated hereby.

13.9    Insurance. The amount of any Liabilities for which any Indemnified Party
is entitled to indemnification under this Agreement or in connection with or
with respect to the transactions contemplated by this Agreement shall be reduced
by any corresponding insurance proceeds, from insurance policies carried by such
Indemnified Party or its Affiliates, that are actually realized by such
Indemnified Party from Third Party insurers with respect to such Liabilities.

13.10    Waiver of Consumer Rights. The Parties each can and do expressly waive
those provisions, if any, of the Texas Deceptive Trade Practices-Consumer
Protection Act, Texas Business and Commerce Code Article 17.41 et seq. (and any
similar Law that gives consumers special rights and protection, including the
Oklahoma Consumer Protection Act, Okla. Stat. tit. 15, §§ 751 through 763).
Buyer acknowledges, represents and warrants to Seller that Buyer is purchasing
the Assets for commercial or business use; that Buyer has Knowledge and
experience in financial and business matters that enable Buyer to evaluate the
merits and risks of a transaction such as this; and that Buyer is not in a
significantly disparate bargaining position with Seller. Further, Buyer
expressly recognizes that the price for which Seller has agreed to perform its
obligations under this Agreement has been predicated upon the inapplicability of
Laws similar

xciii
US-DOCS\112434093.5

--------------------------------------------------------------------------------

to those described in subsections (a) and (b) above, and Buyer further
recognizes that Seller, in determining to proceed with the entering into this
Agreement, has expressly relied on this waiver and the inapplicability of such
Laws. It is not the intent of the Parties to waive, and the Parties shall not
waive, any applicable provision thereof that is prohibited by Law from being
waived.

ARTICLE XIV

(g)    by Buyer or Seller, if:

Environmental Dispute that has not been resolved as of the Outside Termination
Date (and if upon the final resolution of such Title Disputes and Environmental
Disputes, such Buyer’s Closing conditions in Article X are satisfied, the
Closing shall occur within five Business Days after such occurrence).

14.2    Effect of Termination.

xcv
US-DOCS\112434093.5

--------------------------------------------------------------------------------

(a)    If the obligation to close the transactions contemplated by this
Agreement is terminated pursuant to any provision of Section 14.1 hereof, then,
except for the provisions of Section 1.2, 4.1(d) through 4.1(f), Section 4.2,
Section 4.3, Section 9.2, Section 9.5, Section 13.4, Section 13.5, Section 13.7,
this Section 14.2, Section 14.3, Article XVI (other than Section 16.2(b) through
(e), Section 16.3, Section 16.8, Section 16.9 and Section 16.17) and such of the
defined terms in Section 1.1 necessary to give context to the surviving
provisions, this Agreement shall forthwith become void and the Parties shall
have no liability or obligation hereunder.
(b)    If Seller is entitled to terminate this Agreement pursuant to Section
14.1(a) or Section 14.1(e) because of (i) the Willful Breach by Buyer of this
Agreement, or (ii) the failure of Buyer to close in the instance where, as of
the Outside Termination Date, (A) all of the conditions in Article X (excluding
conditions that, by their terms, cannot be satisfied until the Closing) have
been satisfied by Seller (or waived by Buyer), (B) Seller is ready, willing and
able to perform its obligations under Section 12.3, and (C) Buyer nevertheless
elects not to close, then, in either such event, Seller shall be entitled to, at
its option (1) obtain specific performance in lieu of termination or (2)
terminate this Agreement pursuant to Section 14.1(a) or Section 14.1(e), as
applicable, and be entitled to retain the Deposit as liquidated damages for such
termination (the Parties agree that the foregoing liquidated damages are
reasonable considering all of the circumstances existing as of the Execution
Date, shall not serve as a penalty and constitute the Parties’ good faith
estimate of the actual damages reasonably expected to result from such
termination of this Agreement by Seller). Seller agrees that, to the fullest
extent permitted by Law, Seller’s rights set forth in the preceding sentence
shall be the sole and exclusive remedies of Seller (other than with respect to
those provisions that survive termination pursuant to Section 14.2(a)) if the
Closing does not occur as a result of the termination of this Agreement pursuant
to Section 14.1(a) or Section 14.1(e), as applicable. Nothing herein shall be
construed to prohibit Seller from first seeking specific performance, but
thereafter terminating this Agreement and retaining the Deposit as liquidated
damages in lieu of fully prosecuting its claim for specific performance. Each
Party acknowledges that the remedies at Law of Seller for a breach or threatened
breach of this Agreement by Buyer as contemplated pursuant to this Section
14.2(b) may be inadequate and, in recognition of this fact, Seller, without
posting any bond or the necessity or proving the inadequacy as a remedy of
monetary damages, and in addition to all other remedies that may be available,
shall be entitled to obtain equitable relief in the form of specific
performance, a temporary restraining order, a temporary or permanent injunction
or any other equitable remedy that may then be available.
(c)    If this Agreement is terminated by Buyer pursuant to Section 14.1(b) or
Section 14.1(e) because of (i) the Willful Breach by Seller of this Agreement,
or (ii) the failure of Seller to close in the instance where, as of the Outside
Termination Date, (A) all of the conditions in Article XI (excluding conditions
that, by their terms, cannot be satisfied until the Closing) have been satisfied
by Buyer (or waived by Seller), (B) Buyer is ready, willing and able to perform
its obligations under Section 12.3, and (C) Seller nevertheless elects not to
close, then, in either such event, Buyer shall be entitled to terminate this
Agreement pursuant to Section 14.1(b) or Section 14.1(e), as applicable, and be
entitled to return of the Deposit and Buyer shall be entitled to seek actual,
direct damages (subject always to Section 13.7) up to an aggregate amount not
greater than an amount equal to the Deposit amount, which claim shall be
entitled to priority as set forth in Paragraph 30 of the Sale Order. Buyer
agrees that, to the fullest extent permitted by Law, Buyer’s

xcvi
US-DOCS\112434093.5

--------------------------------------------------------------------------------

rights set forth in the preceding sentence shall be its sole and exclusive
remedies of Buyer (other than with respect to those provisions that survive
termination pursuant to Section 14.2(a)) if the Closing does not occur as a
result of the termination of this Agreement pursuant to Section 14.1(b) or
Section 14.1(e), as applicable.
(d)    Notwithstanding anything in this Agreement to the contrary, in the event
this Agreement (A) is terminated pursuant to Sections 14.1(f)(i), 14.1(f)(vi),
14.1(g)(i), or 14.1(g)(ii) or (B) (I) is terminated pursuant to Section 14.1(c)
with respect to the conditions set forth in Section 10.8 or Section 11.8 (II)
KFM Sellers are not also entitled under the terms and conditions of the KFM
Agreement to retain the “Deposit” (as defined in the KFM Agreement), and (III)
Buyer is entitled to the “Break-Up Fee and Expense Reimbursement” (as defined in
the KFM Agreement), Buyer shall be entitled to payment by Seller of an amount
equal to three percent (3%) of the Purchase Price (the “Break-Up Fee and Expense
Reimbursement”). Seller’s obligation (if any) to pay the Break-Up Fee and
Expense Reimbursement (x) shall be subject to consummation of a Highest or
Better Proposal, (y) survive termination of this Agreement and (z) shall be of
no further force and effect if Buyer does not furnish the Commitments to Seller
on or before the Commitment Deadline in accordance with Section 9.4. Seller
shall pay the Break-Up Fee and Expense Reimbursement to Buyer from the proceeds
of the transactions under a Highest or Best Proposal (or from cash of either
Seller, or, if Seller does not have sufficient cash, a successful bidder owned
or controlled by any of Seller’s secured lenders, in either case, to the extent
that such Highest or Best Proposal is the result of a whole or partial credit
bid by any of Seller’s secured lenders to the extent such proceeds of such
Highest or Best Proposal are not sufficient to pay the Break-Up Fee and Expense
Reimbursement), within three (3) days after the consummation of such Highest or
Best Proposal. Buyer’s right to payment of the Break-Up Fee and Expense
Reimbursement shall constitute an administrative expense in these Chapter 11
Cases pursuant to Section 503(b) or 507(a)(2) of the Bankruptcy Code with
priority over any and all administrative expenses of a kind specified in
sections 503(b) and 507(a) of the Bankruptcy Code and senior to all other super
priority administrative expenses in these Chapter 11 Cases, including the
Administrative Adequate Protection Claims (as defined in the Cash Collateral
Order) granted pursuant to the Cash Collateral Order; provided, that any
Break-Up Fee and Expense Reimbursement shall not be payable, nor shall Buyer
seek to compel payment of the Break-Up Fee and Expense Reimbursement, prior to
consummation of a Highest or Best Proposal. Each Party acknowledges that the
agreements contained in this Section 14.2(d) are an integral part of this
Agreement and that, without these agreements, the other Party would not enter
into this Agreement. Buyer represents to Seller that this Section 14.2(d) is a
condition precedent to Buyer’s execution of this Agreement and is necessary to
ensure that Buyer will continue to pursue the proposed acquisition of the
Assets, and Seller acknowledges that the Break-Up Fee and Expense Reimbursement,
if payable hereunder, (i) constitute actual and necessary costs and expenses of
preserving Seller’s estates, within the meaning of Section 503(b) of the
Bankruptcy Code, (ii) are of substantial benefit to Seller’s estates by, among
other things, establishing a bid standard or minimum for other bidders and
placing estate property in a sales configuration mode attracting other bidders
to a potential auction, (iii) are reasonable and appropriate, including in light
of the size and nature of the sale of the Assets by Seller to Buyer contemplated
hereby and the efforts that have been or will be expended by Buyer,
notwithstanding that such sale is subject to higher and better offers, and (iv)
was negotiated by the Parties at arm’s-length and in good faith.

--------------------------------------------------------------------------------

(e)    If this Agreement is terminated by Seller or by Buyer pursuant to Section
14.1 (other than under the circumstances described in Section 14.2(b)), within
two Business Days after such termination, the Parties shall execute and deliver
a joint instruction to Escrow Agent requiring Escrow Agent to disburse the
Deposit to Buyer; provided, however, that if (i) this Agreement is terminated by
Seller due to a failure of the condition in Section 11.8 to be met and (ii) KFM
Sellers are entitled to retain the Deposit (as defined in the KFM Agreement),
then the Parties shall execute and deliver a joint instruction to Escrow Agent
requiring Escrow Agent to disburse the Deposit to Seller.
(f)    Subject to the foregoing, upon the termination of this Agreement neither
Party shall have any other liability or obligation hereunder, and Seller shall
be free to immediately enjoy all rights of ownership of the Assets and to sell,
transfer, encumber or otherwise dispose of the Assets to any Person without any
restriction under this Agreement.

14.3    Return of Documentation and Confidentiality. Upon termination of this
Agreement, Buyer shall return or destroy, at Buyer’s sole expense, all title,
engineering, geological and geophysical data, environmental assessments or
reports, maps and other data and information (including all copies, extracts and
other reproductions, in whole or in part) furnished by Seller or any of its
Affiliates or representatives to Buyer or any of the Buyer Representatives or
prepared by or on behalf of Buyer in connection with its due diligence
investigation of the Assets, in each case, in accordance with the
Confidentiality Agreement and the terms of this Agreement, and an officer of
Buyer shall certify same to Seller in writing. Any oral information will
continue to be subject to the terms of the Confidentiality Agreement
notwithstanding the termination of this Agreement.

ARTICLE XV    
EMPLOYEES

15.1    Business Employees. Within five Business Days after the Execution Date,
Seller shall provide Buyer with a list containing the name, position, exempt or
non-exempt status and location of those current Business Employees, whether or
not actively employed (e.g., including employees on vacation and leave of
absence, including maternity, family and medical leave, sick, military (whether
qualified or otherwise) or short-term disability leave), and the base salary or
hourly wage rate and any target annual incentive applicable to each such
Business Employee, and Seller shall update the list as necessary periodically
prior to the Closing Date, including within five Business Days at Buyer’s
request, to reflect new hires, leaves of absence and employment terminations.
Buyer shall, in its sole discretion, have the option, but not the obligation, to
offer employment as of the Closing Date to such Business Employees as it
determines (the “Offered Employees”) on terms and conditions to be determined in
Buyer’s sole discretion. Not later than ten Business Days prior to the Closing
Date, Buyer shall provide Seller with a list of the material terms (including
compensation details, position and location of employment) of each such offer
made to each Business Employee. Within five Business Days after the Execution
Date and until the Closing Date, Seller shall use its best efforts to provide
Buyer reasonable access to the Business Employees for the sole purpose of
interviewing such Business Employees and discussing employment with Buyer. Buyer
may directly communicate

xcviii
US-DOCS\112434093.5

--------------------------------------------------------------------------------

any offer of employment to a Business Employee; provided, however, that Buyer
will notify Seller prior to contacting any such Business Employee. Each Offered
Employee who accepts Buyer’s offer of employment and actually commences
employment with Buyer shall be referred to as a “Continuing Employee”. Prior to
the Closing Date, Seller shall waive, effective as of the Closing Date, any
restrictions otherwise applicable to a Continuing Employee pursuant to any
agreement or other arrangement between Seller or any of its Affiliates and such
Continuing Employee, which would restrict or otherwise prevent such Continuing
Employee from accepting or commencing employment with Buyer. For the avoidance
of doubt, Seller and Buyer are not, and do not intend to be, joint employers at
any time, and nothing herein may be construed as creating a joint employer
relationship between Seller and Buyer.

15.2    Employee Matters
(a)    Following the Closing Date, in the period required by applicable Law,
Seller shall pay to each Continuing Employee any accrued but unused vacation or
other paid-time off arising under any Benefit Plan that is legally required to
be paid. Seller shall further be responsible as required by Law for all accrued
but unpaid time-off for each employee that is not a Continuing Employee.
(b)    Following Closing, Seller will cease maintaining a group health plan.
Therefore, Buyer agrees and shall be responsible for providing continuation
coverage as required by COBRA, under a group health plan maintained by Buyer to
the Continuing Employees.
(c)    None of the Buyer or any of its Affiliates shall adopt nor become a
sponsoring employer of, nor have any obligations, duties or Liabilities under or
with respect to any of the Benefit Plans. Effective as of the Closing, Seller
shall take all necessary actions to provide for full vesting of all amounts
credited to the accounts of each Continuing Employee under any Benefit Plan that
is intended to be “qualified” under Section 401(a) of the Code or a nonqualified
retirement or deferred compensation plan.
(d)    During the period prior to the Closing Date, Seller shall use
commercially reasonable efforts to make individual natural person independent
contractors related to the Assets and directly engaged by Seller available to
Buyer for the purpose of allowing Buyer to interview each such contractor and
determine the nature and extent of each such Person’s continuation with Buyer,
if any. Seller shall provide to Buyer contact information for Third Party
service providers providing contingent personnel relating to the Assets and
reasonably cooperate in identifying such contingent work force to the extent
requested by Buyer.
(e)    The provisions of this Article XV are solely for the benefit of the
respective parties to this Agreement and nothing in this Article XV or elsewhere
in this Agreement, express or implied, shall create any Third Party beneficiary
or other rights or confer upon any employee, Continuing Employee, or legal
representative or beneficiary or dependent thereof, or any other Person, any
rights or remedies, including any right to employment or continued employment
for any specified period, or compensation or benefits of any nature or kind
whatsoever. Nothing in this Agreement is intended as an amendment, modification
or waiver of the provisions of any benefit or compensation plan, program,
policy, agreement, arrangement or contract (including any Benefit

or maintained by Buyer or any of its Affiliates.

ARTICLE XVI    
MISCELLANEOUS

16.1    Exhibits and Schedules. All of the Exhibits and Schedules referred to in
this Agreement constitute a part of this Agreement. Each Party to this Agreement
and its counsel has received a complete set of Exhibits and Schedules prior to
and as of the execution of this Agreement.

16.2    Expenses and Taxes.
(a)    Except as otherwise specifically provided, all fees, costs and expenses
incurred by the Parties in negotiating this Agreement or in consummating the
transactions contemplated by this Agreement shall be paid by the Party incurring
the same, including legal and accounting fees, costs and expenses.
(b)    All Transfer Taxes and all required documentary, filing and recording
fees and expenses in connection with the filing and recording of the
assignments, conveyances or other instruments required to convey title to the
Assets to Buyer shall be borne by Buyer. The Parties shall cooperate in good
faith to minimize, to the extent permissible under applicable Law, the amount of
any such Transfer Taxes.
(c)    All Taxes that are real property Taxes, ad valorem Taxes, personal
property Taxes and similar obligations attributable to the Assets (the “Property
Taxes”) with respect to the Tax period in which the Effective Time occurs or
estimate(s) thereof shall be apportioned as of the Effective Time between Seller
and Buyer. Such Property Taxes shall be apportioned as of the Effective Time
between Seller and Buyer and included in the Final Settlement Statement. To the
extent the actual amount of any Property Taxes described in this Section 16.2(c)
is not determinable at the time of the Final Settlement Statement, Buyer and
Seller shall utilize the most recent information available in estimating the
amount of such Property Taxes for purposes of the Final Settlement Statement.
For purposes of the foregoing, in each case, the Property Taxes shall be
allocated pro rata per day between the period immediately prior to the Effective
Time and the period beginning on the Effective Time, with the portion of
Property Taxes attributable to the period immediately prior to the Effective
Time being allocated to Seller, and the portion of the Property Taxes
attributable to the period beginning on the Effective Time being allocated to
Buyer. Seller shall pay or cause to be paid to the taxing authorities all Asset
Taxes due prior to the Closing Date. Buyer shall pay or cause to be paid to the
taxing authorities all Property Taxes due after the Closing relating to the Tax
period in which the Effective Time occurs without thereby becoming entitled to
any additional payment from Seller other than as required by Article III and
neither party shall be liable to make any additional payment to the other party
in the event an estimate of such Property Taxes used in arriving at the Final
Settlement Statement varies from the actual amount thereof.

c

--------------------------------------------------------------------------------

(d)     All Taxes attributable to the Assets that are based upon or measured by
the operation of the Assets, the production of Hydrocarbons therefrom or the
receipt of proceeds therefrom including severance, production, sales, use,
excise and similar Taxes, but excluding, for the avoidance of doubt, income,
capital gains and franchise Taxes, Property Taxes and Transfer Taxes (the
“Production Taxes”) shall be apportioned between Seller and Buyer as of the
Effective Time as if the Tax period ended immediately prior to the Effective
Time, with the portion of Production Taxes attributable to the period ending
immediately prior to the Effective Time being allocated to Seller, and the
portion of the Production Taxes attributable to the period beginning on the
Effective Time being allocated to Buyer. To the extent the actual amount of any
Production Taxes described in this Section 16.2(d) is not determinable at the
time of the Final Settlement Statement, Buyer and Seller shall utilize the most
recent information available in estimating the amount of such Production Taxes
for purposes of the Final Settlement Statement. Seller shall, in accordance with
applicable laws and regulations, pay or withhold or cause to be paid or withheld
all such Taxes that have accrued with respect to production prior to Closing and
shall file all statements, returns, and documents incident thereto. Buyer shall
pay or cause to be paid all such Taxes that accrue with respect to production
from Closing onward and shall file all statements, returns, and documents
incident thereto. For Tax periods in which the Effective Time occurs, Seller
agrees to forward to Buyer copies of any Production Tax reports and returns
received by Seller after Closing and to provide Buyer with any information
Seller has that is necessary for Buyer to file any required Production Tax
reports and returns related to the Assets, which Production Tax returns and
reports Buyer agrees to file, and which Production Taxes Buyer agrees to pay or
cause to be paid to the extent due after the Closing Date without thereby
becoming entitled to any additional payment from Seller other than as required
by Article III.
(e)    Buyer and Seller agree to furnish or cause to be furnished to the other,
upon request, as promptly as practicable, such information and assistance
relating to the Assets, including access to books and Records, as is reasonably
necessary for the filing of all Tax Returns by Buyer or Seller, the making of
any election relating to Taxes, the preparation for any audit by any taxing
authority and the prosecution or defense of any claim, suit or proceeding
relating to any Tax.
(f)    Any payments made to any Party pursuant to Article XIII shall constitute
an adjustment to the Purchase Price for Tax purposes and shall be treated as
such by Buyer and Seller on their respective Tax Returns to the extent permitted
by Law.
(g)    If Seller is legally and contractually entitled to cause each Tax
Partnership (i) to make a valid election under Section 754 of the Code for the
taxable year that includes the Closing Date (the “Section 754 Election”) and
(ii) to make the election under Section 6226(a) of the Code (or any similar
provision of state or local Law) with respect to the alternative to payment of
an imputed underpayment by the Tax Partnership with respect to any taxable year
beginning prior to the Closing Date and take other actions such as filings,
disclosures and notifications necessary to effectuate such election (the
“Push-Out Election”), Seller shall require the Tax Partnership (A) to cause the
partnership representative and designated individual, if any, of the Tax
Partnership to make the Push-Out Election and (B) to make the Section 754
Election. If Seller is not legally and contractually entitled to cause each Tax
Partnership to make the Section 754 Election and the Push-Out Election, Seller
shall use commercially reasonable efforts to cause the Tax

Partnership (x) to cause the partnership representative and designated
individual, if any, of the Tax Partnership to make the Push-Out Election and (y)
to make the Section 754 Election.

16.3    Value Allocations for Tax Purposes. Seller and Buyer agree that the
portion, if any, of the Adjusted Purchase Price and any other items treated for
federal Tax purposes as consideration for a sale transaction (collectively, the
“Allocable Amount”) shall be allocated among the various Assets for federal and
state income Tax purposes in accordance with Section 1060 of the Code and
Treasury Regulations promulgated thereunder. The initial draft of such
allocations shall be prepared by Seller and shall be provided to Buyer
concurrently with the delivery of the Final Settlement Statement and for the
avoidance of doubt shall be prepared in a manner consistent with the Allocated
Values of the Title Wells determined pursuant to Section 3.6 to the maximum
extent permitted by applicable Law. Seller and Buyer shall then prepare a
mutually agreeable final schedule of any Allocable Amount among the Assets (as
adjusted, the “Allocation Schedule”), which agreement shall be consistent with
Section 3.6 and will not be unreasonably withheld, conditioned or delayed by
either Party. The Allocation Schedule shall be updated to reflect any
adjustments to the Allocable Amount. If required, the allocation of the
Allocable Amount shall be reflected on a completed Internal Revenue Service Form
8594 (Asset Acquisition Statement under Section 1060), which such form will be
timely filed separately by Seller and Buyer with the Internal Revenue Service
pursuant to the requirements of Section 1060(b) of the Code. Neither Buyer nor
Seller shall take any Tax position inconsistent with such allocation and neither
Buyer nor Seller shall agree to any proposed adjustment to the Allocation by any
Taxing authority unless required by a “determination” within the meaning of
Section 1313(a) of the Code or with the prior written consent of the other
Party; provided, however, that nothing contained herein shall prevent Buyer or
Seller from settling any proposed deficiency or adjustment by any Taxing
authority based upon or arising out of the Allocation, and neither Buyer nor
Seller shall be required to litigate before any court any proposed deficiency or
adjustment by any taxing authority challenging such Allocation. The procedures
of Section 3.4(a) shall be applied in the event of a dispute for any item under
this Section 16.3, mutatis mutandis.

16.4    Assignment; Liquidating Trust. Neither this Agreement, nor any rights,
obligations, liabilities, covenants, duties or responsibilities hereunder, may
be assigned by any Party, in whole or in part, without the prior written consent
of the other Party, which consent may be withheld for any reason; provided,
however, that Buyer shall be permitted to assign all or any portion of its
rights or obligations under this Agreement to one or more of its Affiliates
without the prior consent of Seller, provided that the assigning Party shall
remain primarily liable all obligations of Buyer hereunder together with its
assignee. Any assignment in violation of the foregoing shall be deemed void ab
initio; provided, further, that, Buyer may assign all or any portion of its
rights and obligations pursuant to this Agreement to the Debt Financing Sources
pursuant to the terms of the Commitment Documentation for purposes of creating a
security interest herein or otherwise assigning as collateral in respect of the
Commitment. No assignment by any Party of this Agreement shall relieve such
Party of any of its obligations (including indemnity obligations), liabilities,
covenants, duties or responsibilities hereunder without the non-assigning
Party’s prior written consent (which may be withheld for any reason). If a
Liquidating Trust is established, from and after the formation of the
Liquidating Trust all rights and obligations of Seller under this Agreement
shall accrue to and be for the benefit of and shall be exercisable by the
Liquidating

US-DOCS\112434093.5

--------------------------------------------------------------------------------

Trust, as provided by any order of the Bankruptcy Court and the Liquidating
Trustee shall be entitled to exercise all of the rights of Seller under this
Agreement.

16.5    Preparation of Agreement. Both Seller and Buyer and their respective
counsel participated in the preparation of this Agreement. In the event of any
ambiguity in this Agreement, no presumption shall arise based on the identity of
the draftsman of this Agreement.

16.6    Publicity; Disclosure of Agreement and Transaction. Seller and Buyer and
their respective Affiliates, if applicable, shall consult with each other with
regard to all press releases or other public or private announcements issued or
made at or prior to the Closing concerning this Agreement or the transactions
contemplated herein, and neither Buyer nor Seller shall issue, and each of them
shall not permit any Affiliate to issue any such press release or other
publicity without the prior written consent of the other Party, which consent
shall not be unreasonably withheld, conditioned or delayed. The foregoing
limitations shall not (A) restrict disclosures by a Party that are permitted or
required under this Agreement, including Section 3.4(a), (B) restrict
disclosures by Buyer or Seller that are required by applicable securities or
other Laws or regulations or the applicable rules of any Governmental Authority
or stock exchange having jurisdiction over the disclosing Party or its
Affiliates, (C) prevent Buyer or Seller from recording the Instruments of
Conveyance or any federal or state assignments delivered at Closing or from
complying with any disclosure requirements of Governmental Authorities that are
applicable to the transfer of the Assets from Seller to Buyer, (D) prevent Buyer
or Seller from making any disclosure of information relating to this Agreement
if made in a manner, under conditions and to Persons that would be permitted
under the terms of the Confidentiality Agreement so long as such Person
continues to hold such information confidential on the same terms as set forth
in such agreement, and (E) prevent Seller from making disclosures to the extent
reasonably required in connection with complying with Preferential Purchase
Rights and seeking to obtain Consents.

16.7    Notices. All notices and communications which are required or may be
given to a Party hereunder shall be in writing and shall be deemed to have been
duly given upon the earliest of: (a) if by personal delivery, then the date of
delivery if such date is a Business Day during normal business hours, or, if
such date is not a Business Day during normal business hours, then the next
Business Day, (b) if sent by U.S. certified mail, postage prepaid, return
