any right, title, or interest in any such records and Tax Returns)
(collectively, the “Records”);
(m)    all rights, claims and causes of action (including claims for adjustments
and refunds) to the extent attributable to (i) the other Conveyed Interests
insofar as accruing from and after the Effective Time, and/or (ii) any of the
Assumed Obligations;
(n)    all accounts receivable for which the Purchase Price was adjusted
pursuant to Section 3.3(a)(vii), and all claims, causes of action, and rights

property or contract right that, in each case, is primarily related to and
arises from or, in the case of clause (i), is necessary for, (i) the ownership,
operation, use or development of the other Conveyed Interests (as owned,
operated, used, or developed by Seller or its Affiliates immediately prior to
the Effective Time) and/or (ii) the Assumed Obligations; provided, that, for the
avoidance of doubt, the items described in the definition of “Excluded Assets
and Other Matters” will be deemed excluded from any real property, personal
property or contract right that would otherwise be covered by, through or under
this Section 2.1(o).
For the avoidance of doubt, the Parties agree that the term “Subject
Properties,” as used in this Agreement, means the 100% interest on an 8/8ths
basis in and to the Leases, the Wells, the Units, the Hydrocarbons and minerals
described in Section 2.1(c), the Other Wells and the personal property, fixtures
and buildings described in Section 2.1(d) or Section 2.1(f), the Surface Fee
Interests, the Pipeline Systems, the Rights-of-Way and the Personal Property, of
which the Conveyed Interests are the whole or a part, as applicable, less and
except the Excluded Assets and Other Matters.
2.2    Excluded Assets and Other Matters. Seller shall reserve and retain all of
the Excluded Assets and Other Matters.
2.3    Revenues and Expenses.
(a)    Except as expressly provided otherwise in this Agreement (including
Sections 2.3(b) and 3.3), Seller shall remain entitled to all of the rights of
ownership (including the right to all production, proceeds of production, and
other proceeds) and shall remain responsible (by payment, through the
adjustments to the Purchase Price under this Agreement or otherwise) for all
Operating Expenses, in each case attributable to the Conveyed Interests for the
period of time prior to the Effective Time. Except as expressly provided
otherwise in this Agreement (including Section 3.3), and subject to the
occurrence of 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 Conveyed Interests for the period of time
commencing at the Effective Time, and shall be responsible for (by payment,
through the adjustments to the Purchase Price under this

4

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

Agreement or otherwise) all Operating Expenses attributable to the Conveyed
Interests for the period of time commencing at the Effective Time (including any
pre-payments made before the Effective Time for services, work or goods
performed or to be performed, or delivered or to be delivered after the
Effective Time). Such amounts which are received or paid prior to Closing shall
be accounted for in the Preliminary Settlement Statement or Final Settlement
Statement, as applicable; provided, however, that the Preliminary Settlement
Statement may contain estimated amounts of Seller made in good faith. Such
amounts which 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.
(b)    Except as otherwise provided in this Section 2.3(b), after the Parties’
agreement upon the Final Settlement Statement, if, based on the Effective Time
allocation described in Section 2.3(a) (except to the extent constituting part
of the Assumed Obligations), (i) either Party receives monies belonging to the
other Party, including proceeds of production, then such amount shall, within
30 days after the end of the calendar month in which such amounts were received,
be paid over to the proper Party, (ii) either Party pays monies for Operating
Expenses which are the obligation of the other Party, then such other Party
shall, within 30 days after the end of the calendar month in which the
applicable invoice and proof of payment of such invoice were received, reimburse
the Party which paid such Operating Expenses, (iii) a Party receives an invoice
of an expense or obligation (other than an invoice of an expense or obligation
with respect to Asset Taxes, Income Taxes or Transfer Taxes) which is owed by
the other Party, such Party receiving the invoice shall promptly forward such
invoice to the Party obligated to pay the same, and (iv) an invoice or other
evidence of an obligation (other than an obligation with respect to Asset Taxes,
Income Taxes or Transfer Taxes) is received by a Party, which is partially an
obligation of both Seller and Buyer, then the Parties shall consult with each
other, and each shall promptly pay its portion of such obligation to the obligee
thereof. Subject to, and without prejudice to, Buyer’s rights and remedies under
Section 13.2(c) with respect to Operating Expenses that constitute Specified
Obligations, the Final Settlement Statement shall be the final accounting for
any and all Operating Expenses, and there shall be no adjustment for, or
obligation to pay, any Operating Expenses between the Parties following the
Final Settlement Statement.
(c)    Each of Seller and Buyer shall be permitted to offset any Operating
Expenses owed by such Party to the other Party pursuant to this Section 2.3
against amounts owing by the second Party to the first Party pursuant to this
Section 2.3.
ARTICLE III
PURCHASE PRICE
3.1    Purchase Price. The purchase price for the transfer of the Conveyed
Interests and the transactions contemplated hereby shall be $205,000,000 (the
“Purchase Price”), as adjusted pursuant to this Agreement, payable by Buyer
(less (a) the Deposit, which will be distributed at Closing as described in
Section 3.2 and (b) the Defect Escrow Amount, if applicable, which will be paid
into the Escrow Account pursuant to Section 3.6(c) and distributed therefrom
pursuant to Section 3.6(b)) to Seller at Closing by wire transfer in immediately
available funds to a bank account

5

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

of Seller (the details of which shall be provided by Seller to Buyer in the
Preliminary Settlement Statement).
3.2    Deposit. No later than one Business Day following the execution of this
Agreement, Buyer shall deposit by wire transfer in same day funds with the
Escrow Agent the sum of $10,250,000, representing 5% of the Purchase Price (such
amount, including any interest earned thereon, the “Deposit”) to be held in, and
distributed from, the Escrow Account pursuant to the Escrow Agreement and this
Agreement. If Closing occurs, the Deposit shall be applied toward the Adjusted
Purchase Price at Closing and the Parties shall instruct the Escrow Agent to pay
the Deposit to Seller at Closing. Otherwise the Deposit shall be handled in
accordance with Section 14.2.
3.3    Adjustment to Purchase Price. The Purchase Price shall be adjusted as
follows (without duplication), and the resulting amount shall be herein called
the “Adjusted Purchase Price”:  
(a)    The Purchase Price shall be adjusted upward by the following amounts:
(i)    an amount equal to the value of all Hydrocarbons (other than Tank
Bottoms) attributable to the Conveyed Interests that are, as of the Effective
Time, in storage or existing in stock tanks, pipelines and/or plants (including
inventory and line fill), the value to be based upon the price paid to Seller in
connection with the sale of such Hydrocarbons (or if there is no sales of such
Hydrocarbons, the value to be based upon the contract price for those
Hydrocarbons in effect as of the Effective Time), net of amounts payable as
Burdens on such production;
(ii)    an amount equal to all Operating Expenses and all other costs and
expenses paid by Seller or any of its Affiliates that are attributable to the
Conveyed Interests (other than Overhead Costs, Asset Taxes, Income Taxes and
Transfer Taxes) for the period of time from and after the Effective Time,
whether paid before or after the Effective Time (including any pre-payments made
before the Effective Time for services, work or goods performed or to be
performed, or delivered or to be delivered after the Effective Time), including
(A) Burdens, (B) bond and insurance premiums paid by or on behalf of Seller or
any of its Affiliates with respect to the period of time commencing at the
Effective Time, and (C) rentals and other lease maintenance payments;
(iii)    the amount of all Asset Taxes allocated to Buyer in accordance with
Section 15.2 but that have been paid or are payable by Seller as of the date the
Final Price is determined;
(iv)    subject to Section 3.9, to the extent that Seller has underproduced any
Hydrocarbons as of the Effective Time, as complete and final settlement of all
Well Imbalances attributable to the Conveyed Interests, an amount equal to the
product of the underproduced gaseous Hydrocarbon volumes set forth on Schedule
7.10 times $2.34/MMBtu;
(v)    subject to Section 3.9, to the extent that Seller has over-delivered any
Hydrocarbons as of the Effective Time, as complete and final settlement of all
Pipeline Imbalances

6

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

attributable to the Conveyed Interests, an amount equal to the product of the
over-delivered gaseous Hydrocarbons volumes set forth on Schedule 7.10 times
$2.34/MMBtu;
(vi)    the Overhead Costs;
(vii)    to the extent Seller has not received or otherwise been reimbursed
prior to Closing, the aggregate amount of accounts receivable billed after the
Effective Time with respect to the total amount of costs and expenses paid by
Seller on behalf of or that are properly chargeable to any Third Party with
respect to any Subject Property for periods of time after the Effective Time,
which adjustment shall not be made at Closing but shall be made in connection
with the Final Settlement Statement and taken into account in the Final Price;
and
(viii)    any other amount provided for elsewhere in this Agreement or otherwise
agreed upon in writing by Seller and Buyer as an upward adjustment to the
Purchase Price.
(b)    The Purchase Price shall be adjusted downward by the following amounts:
(i)    an amount equal to all proceeds actually received by Seller or its
Affiliates attributable to the sale of Hydrocarbons (A) produced from or
allocable to the Conveyed Interests during the period of time commencing at the
Effective Time or (B) contained in storage or existing in stock tanks, pipelines
and/or plants (including inventory and line fill) as of the Effective Time for
which an upward Purchase Price adjustment was made pursuant to
Section 3.3(a)(i), in each case, net of marketing expenses (other than Operating
Expenses and other expenses taken into account pursuant to Section 3.3(a),
Income Taxes, Asset Taxes and Transfer Taxes) directly incurred in earning or
receiving such proceeds and that are paid by Seller (and not reimbursed to
Seller by a Third Party purchaser);
(ii)    an amount equal to all Operating Expenses and all other costs and
expenses paid after the Effective Time by Buyer or any of its Affiliates that
are attributable to the Conveyed Interests (other than Overhead Costs, Asset
Taxes, Income Taxes and Transfer Taxes) for the period prior to the Effective
Time, including (A) Burdens, (B) bond and insurance premiums paid by or on
behalf of Buyer or any of its Affiliates with respect to the period of time
prior to the Effective Time, and (C) rentals and other lease maintenance
payments;
(iii)    the amount of all Asset Taxes allocated to Seller in accordance with
Section 15.2 but that have been paid or are payable by Buyer as of the date the
Final Price is determined;
(iv)    any reduction to the Purchase Price pursuant to Seller’s election under
Section 5.3(d)(i);
(v)    any reduction to the Purchase Price pursuant to Seller’s election under
Section 6.1(c)(i);

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

(vi)    the Allocated Value of the Conveyed Interests excluded from the
transactions contemplated hereby pursuant to Sections 4.1(b), 5.5(a)(i),
5.5(b)(i) or 6.1(c);
(vii)    subject to Section 3.9, to the extent that Seller has overproduced any
Hydrocarbons as of the Effective Time, as complete and final settlement of all
Well Imbalances attributable to the Conveyed Interests, an amount equal to the
product of the overproduced gaseous Hydrocarbon volumes set forth on Schedule
7.10 times $2.34/MMBtu;
(viii)    subject to Section 3.9, to the extent that Seller has under-delivered
any Hydrocarbons as of the Effective Time, as complete and final settlement of
all Pipeline Imbalances attributable to the Conveyed Interests, an amount equal
to the product of the under-delivered gaseous Hydrocarbon volumes set forth on
Schedule 7.10 times $2.34/MMBtu;
(ix)    an amount equal to all proceeds from sales of Hydrocarbons relating to
the Conveyed Interests and payable to owners of working interests, Burdens or
other similar interests (in each case) that are held by Seller or its Affiliates
in suspense as of the Closing Date (or a date after Closing when the liability
to such suspense accounts are transferred from Seller to Buyer), which
adjustment shall not be made at Closing but shall be made in connection with the
Final Settlement Statement and taken into account in the Final Price; and
(x)    any other amount provided for elsewhere in this Agreement or otherwise
agreed upon in writing by Seller and Buyer as a downward adjustment to the
Purchase Price.
3.4    Adjustment Methodology. When available, actual figures will be used for
the adjustments to the Purchase Price at Closing. To the extent actual figures
are not available, estimates made by the relevant Party in good faith will be
used subject to final adjustments in accordance with Section 3.6 and
Section 3.7. Seller will provide supporting documents and calculations, as
applicable, for Purchase Price adjustments included in the Preliminary
Settlement Statement and/or the Final Settlement Statement. In the event the
written report delivered by Buyer to Seller pursuant to Section 3.5 or a Dispute
Notice, if applicable, proposes an adjustment to the Purchase Price under
Section 3.3(b)(ii), Buyer will provide supporting documents (if any) for such
proposed adjustment when it delivers such written report or Dispute Notice to
Seller.
3.5    Preliminary Settlement Statement. Not less than five Business Days prior
to Closing, Seller shall prepare and submit to Buyer for review a draft
settlement statement (the “Preliminary Settlement Statement”) that shall set
forth the Adjusted Purchase Price, reflecting each adjustment made in accordance
with this Agreement as of the date of preparation of such Preliminary Settlement
Statement and the calculation of the adjustments used to determine such amount
(in each case, without duplication of any amounts), together with the
designation of Seller’s accounts for the wire transfer of funds as set forth in
Section 3.1 and Section 12.3(d). Within three Business Days after receipt of the
Preliminary Settlement Statement, Buyer will deliver to Seller a written report
containing all changes, with explanation therefor, that Buyer proposes to be
made to the Preliminary Settlement Statement, if any. The Parties shall in good
faith attempt to agree on the Preliminary Settlement Statement as soon as
possible after Seller’s receipt of Buyer’s written report. The Preliminary
Settlement Statement, as agreed upon by the Parties, will be used to adjust

8

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

the Purchase Price at Closing (the Purchase Price, as adjusted at Closing and
(a) less the Deposit and (b) downward adjusted by, among other things, any
amounts deposited into escrow pursuant to Section 3.6(c), the “Closing
Payment”); provided that if the Parties do not agree on an adjustment set forth
in the Preliminary Settlement Statement prior to the Closing, the amount of such
adjustment set forth in the Preliminary Settlement Statement as presented by
Seller in good faith will be used to adjust the Purchase Price at Closing.
3.6    Final Settlement Statement.
(a)    On or before 120 days after the Closing, Seller shall deliver to Buyer a
final settlement statement (the “Final Settlement Statement”) prepared by Seller
based on actual income and expenses during the Interim Period and which (i)
takes into account all final adjustments made to the Purchase Price and (ii)
shows the resulting final Adjusted Purchase Price (in each case, without
duplication of any amounts) (the “Final Price”). The Final Settlement Statement
shall set forth the actual proration of the amounts required by this Agreement.
As soon as practicable, and in any event within 30 days after receipt of the
Final Settlement Statement, Buyer will deliver to Seller a written report
containing any proposed changes to the Final Settlement Statement and an
explanation of any such changes and the reasons therefor (the “Dispute Notice”).
Any changes not so specified in the Dispute Notice shall be deemed waived and
Seller’s determinations with respect to all such elements of the Final
Settlement Statement that are not addressed specifically in the Dispute Notice
shall prevail. If Buyer fails to timely deliver a Dispute Notice to Seller
containing changes Buyer proposes to be made to the Final Settlement Statement,
the Final Settlement Statement as delivered by Seller will be deemed to be
correct and mutually agreed upon by the Parties, and will be final and binding
on the Parties and not subject to further audit or arbitration.
(b)    At such time that the Final Price set forth in the Final Settlement
Statement is mutually agreed upon by Seller and Buyer (or deemed to be mutually
agreed upon by the Parties pursuant to Section 3.6(a)), or, if the Final
Settlement Statement is not mutually agreed upon (or deemed to be mutually
agreed upon) by the Parties, at such time that the matters subject to any
Dispute Notices, if applicable, are resolved pursuant to Section 3.7, the Final
Settlement Statement and the Final Price shall be final and binding on the
Parties, subject to the provisions of Section 2.3(b). If the Final Price is more
than the Buyer Amount P-A-C (such difference, the “Payable Amount”), then (i)
the Defect Escrow Amount shall be released to Seller from the Escrow Account and
(ii) the remaining portion of the Payable Amount owed by Buyer shall be paid by
Buyer to Seller within 10 days after final determination of such owed amounts in
accordance herewith. However, in the event that the Buyer Amount P-A-C is more
than the Final Price (such difference, the “Refundable Amount”), then (A) if the
Refundable Amount is less than the Defect Escrow Amount, (1) an amount that is
equal to the Refundable Amount shall be released to Buyer from the Escrow
Account and (2) the remaining portion of the Defect Escrow Amount shall be
released to Seller or (B) if the Refundable Amount is greater than the Defect
Escrow Amount, (i) the Defect Escrow Amount shall be released to Buyer from the
Escrow Account and (ii) the remaining portion of the Refundable Amount owed by
Seller shall be paid by Seller to Buyer, in each case, within 10 days after
final determination of such owed amounts in accordance herewith. For
illustrative purposes only, Schedule 3.6(b) sets forth examples of calculations
for the Payable Amount and the Refundable Amount. All amounts paid by any Party
pursuant to this Section 3.6 shall be delivered in United

9

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

States currency by wire transfer of immediately available funds to the account
specified in writing by the relevant Party. The Parties shall instruct the
Escrow Agent to release the portions of the Defect Escrow Amount payable to the
applicable Party (or Parties) within the 10 day period referenced above.
(c)    At the Closing, if applicable, Buyer shall deposit into the Escrow
Account an amount equal to the Defect Escrow Amount. For purposes of this
Agreement, the “Defect Escrow Amount” shall mean (i) the aggregate amount of
Title Defect Amounts asserted by Buyer with respect to all uncured Title Defects
that were timely and properly asserted by Buyer pursuant to Section 5.3(a) and
that Seller has timely elected to cure or that the Parties have not agreed upon
prior to the sixth Business Day prior to Closing, plus (ii) (A) the Remediation
Amounts asserted by Buyer for all uncured Environmental Defects that were timely
and properly asserted by Buyer pursuant to Section 6.1(a) and that Seller has
timely elected to cure or that the Parties have not agreed upon prior to the
sixth Business Day prior to Closing (including any dispute as to whether Seller
has cured such asserted Environmental Defects), and (B) the Allocated Values of
any Conveyed Interests for which any portion of a Phase II ESA will be completed
post-Closing pursuant to Section 4.1(b)(B) (for purposes of this clause (c),
“Phase II Conveyed Interests”) less (iii) the aggregate amount of Title Benefits
Amounts (without duplication of any Title Benefit Amounts already used hereunder
to offset Title Defect Amounts and/or Remediation Amounts) asserted by Seller
with respect to all Title Benefits that were timely and properly asserted by
Seller pursuant to Section 5.3(b) and that Buyer has conceded or are the subject
of a Title Dispute, in each case, after application of the Individual Title
Defect Threshold, the Individual Environmental Threshold, and (without
duplication of the application thereof) the Aggregate Deductible and other
limitations set forth in Section 5.3(i) or Section 6.1(e), as applicable. For
the avoidance of doubt, the Defect Escrow Amount shall be the amount of the
Purchase Price that, at Closing, has been reduced as a result of (A) uncured
Title Defects for which Seller has made a timely election to cure pursuant to
Section 5.3(d), (B) Title Defects that the Parties have not agreed upon prior to
the sixth Business Day prior to Closing, (C) uncured Environmental Defects for
which Seller has made a timely election to cure pursuant to Section 6.1(c), (D)
Environmental Defects that the Parties have not agreed upon prior to the sixth
Business Day prior to Closing, and (E) Phase II Conveyed Interests, less the
Title Benefit Amounts referenced in clause (iii) above.
3.7    Disputes.
(a)    If Seller and Buyer are unable to resolve the matters addressed in a
Dispute Notice (if any), the Parties agree that for a 30 day period following
written notice from either Party, an officer or representative designated by
each Party shall attempt to resolve such dispute.
(b)    If Seller and Buyer are unable to resolve their dispute within the period
set forth in Section 3.7(a), either Party may initiate the arbitration process
set forth in this Section 3.7(b) by sending a written notice to the other Party
(the “Arbitration Notice”). Each Party shall within 14 Business Days after the
delivery of the Arbitration Notice, summarize its position with regard to such
dispute in a written document of 20 pages or less and submit such summaries to
the Dallas, Texas office of Deloitte & Touche LLP, or such other Person as the
Parties may mutually select (the “Accounting Arbitrator”), together with the
Dispute Notice, the Arbitration Notice, the Final

10

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

Settlement Statement and any other documentation such Party may desire to
submit. 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, based on the materials submitted to the Accounting
Arbitrator as described above. Any decision rendered by the Accounting
Arbitrator pursuant hereto shall be final, conclusive and binding on Seller and
Buyer and will be taken into account as part of the Final Price determination
pursuant to Section 3.6 and will be enforceable against the Parties in any court
of competent jurisdiction. The Accounting Arbitrator shall act as an expert for
the limited purpose of determining the specific dispute submitted by either
Party and may not award damages, interest or penalties to either Party with
respect to any matter, except as otherwise provided in the following sentence.
The costs of the Accounting Arbitrator and the reasonable legal costs and other
expenses incurred by the Parties in connection with the arbitration shall be
borne pro rata between the Parties with each Party being responsible for such
costs and expenses to the extent the Accounting Arbitrator has not selected such
Party’s position on an aggregate dollar basis with respect to all amounts
submitted for resolution by the Accounting Arbitrator.
3.8    Allocation of Purchase Price; Allocated Values. Solely for the purposes
of determining the value of Conveyed Interests in connection with any Title
Defect, Environmental Defect, Preferential Purchase Right, Required Consent,
and/or breach of Special Warranty under this Agreement and the value of the Tag
Interests, Buyer and Seller have allocated the Purchase Price among the Conveyed
Interests as set forth on Exhibit A and Exhibit B. The value so allocated to a
particular Conveyed Interest identified on Exhibit A and Exhibit B may be
referred to as “Allocated Value” for that Conveyed Interest. Buyer and Seller
agree that such allocation is reasonable and shall not take any position
inconsistent therewith, including notices to holders of Preferential Purchase
Rights. Neither Party, however, makes any representations or warranties as to
the accuracy of such value or allocation.
3.9    Allocation for Imbalances at Closing. If, prior to Closing, the
Imbalances set forth in Schedule 7.10 change or, prior to the date the Final
Price is determined as provided in Section 3.6 or 3.7, as applicable, either
Party discovers an error in the Imbalances set forth in Schedule 7.10, then the
Purchase Price shall be further adjusted pursuant to Section 3.3(a)(iv),
3.3(a)(v), 3.3(b)(vii), or 3.3(b)(viii) as applicable, and Schedule 7.10 will be
deemed amended immediately prior to Closing to reflect the Imbalances for which
the Purchase Price is so adjusted.
ARTICLE IV
ACCESS / DISCLAIMERS
4.1    Access.
(a)    From and after the Execution Date and until two (2) Business Days prior
to Closing (or earlier termination of this Agreement pursuant to the terms
herein), but subject to the other provisions of this Section 4.1 and obtaining
any required consents of Third Parties, including Third Party operators of the
Subject Properties (with respect to which consents Seller shall use commercially
reasonable efforts to request, but shall not be obligated to expend any monies,
except as may be agreed to be paid or reimbursed by Buyer), Seller shall afford
to Buyer and its authorized representatives (“Buyer’s Representatives”)
reasonable access, during normal business hours, to

11

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

the Subject Properties, and all Records in Seller’s or its Affiliates’
possession, at such time to the extent necessary to conduct investigations and
due diligence on the Conveyed Interests, including, prior to the Environmental
Defect Claim Date, the title or environmental review described in Article V and
Article VI. All investigations and due diligence conducted by Buyer or any
Buyer’s Representative shall be conducted at Buyer’s sole cost, risk and expense
and any conclusions made from any examination done by Buyer or any Buyer’s
Representative shall result from Buyer’s own independent review and judgment.
(b)    From the Execution Date until the Environmental Defect Claim Date,
subject to the terms and conditions below, Buyer’s inspection right with respect
to the Environmental Condition of the Subject Properties shall be limited to
undertaking a Phase I Environmental Site Assessment of the Subject Properties
conducted by Buyer’s employees, or a reputable environmental consulting or
engineering firm approved in advance in writing by Seller (such approval not to
be unreasonably withheld, conditioned, or delayed), and may include only visual
inspections and record reviews relating to the Subject Properties. In conducting
such inspection, Buyer shall not operate any equipment or conduct any testing or
sampling of soil, groundwater or other materials (including any invasive testing
or sampling for Hazardous Substances, Hydrocarbons or NORM). Seller or Seller’s
designee shall have the right to be present during any stage of the assessment.
Buyer shall give Seller reasonable prior written notice before gaining physical
access to any of the Subject Properties, and Seller or its designee shall have
the right but not the obligation to accompany Buyer and Buyer’s Representatives
whenever Buyer and/or Buyer’s Representatives gain physical access to any
Subject Property. Notwithstanding anything contained herein to the contrary,
Buyer shall not have access to, and shall not be permitted to conduct any
inspections (including any Phase I Environmental Site Assessment) with respect
to, any Subject Property with respect to which Seller does not have the
authority to grant access for such due diligence; provided that Seller shall
reasonably request (with respect to which request Seller shall not be obligated
to expend any monies, unless Buyer agrees to reimburse Seller therefor) access
rights from Third Parties for Buyer to conduct such inspections (including any
Phase I Environmental Site Assessment) with respect to, such Subject Property.
Buyer will use reasonable efforts to complete all such Phase I Environmental
Site Assessments within 30 days of the Execution Date. If, and only if, Buyer in
good faith believes that a Phase I Environmental Site Assessment determines that
Phase II sampling or other invasive investigations (“Phase II ESA”) are
necessary in order for Buyer to prove the existence of an Environmental Defect
or establish a defensible Remediation Amount with respect to the applicable
Conveyed Interest, Buyer shall, if it desires to perform a Phase II ESA as
described in such Phase I Environmental Site Assessment, (i) furnish Seller with
a written description of the proposed scope of such sampling or invasive
activities, including a description of the specific activities to be conducted,
and a description of the approximate location and expected timing of such
activities, which proposed scope shall be consistent with what was determined to
be necessary in the Phase I Environmental Site Assessment (a “Phase II
Request”), and, (ii) subject to the preceding sentence, obtain the prior written
consent of Seller (such consent not to be unreasonably withheld, conditioned, or
delayed) to undertake the sampling or invasive activities described in the Phase
II Request. In the event that (A) (1) Seller does not approve any such Phase II
Request on any Subject Property operated by Seller or its Affiliates within five
Business Days of Buyer’s delivery of such request or (2) with respect to any
other Subject Property, Buyer, due to un-obtained consents or approvals of Third
Parties with respect to accessing such Subject Property, was unable to timely
perform a

12

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

Phase I Environmental Site Assessment or Phase II ESA, as the case may be, Buyer
shall have the right, but not the obligation, to exclude any or all of the
affected Conveyed Interests from the transactions contemplated hereby, and any
such Conveyed Interests that are so excluded shall be deemed hereunder to be
Excluded Assets and Other Matters and the Purchase Price shall be adjusted
downward by the aggregate of the Allocated Values thereof or (B) Seller provides
its approval of the Phase II Request, the Environmental Defect Claim Date, the
Cure Period and the Dispute Date (in each case, with respect to the affected
Conveyed Interests only and notwithstanding anything to the contrary herein) and
all other associated dates herein will be extended for a reasonable period of
time (as set forth in the Phase II Request) in order for Buyer to perform and
complete its Phase II ESA, provided that (x) the Closing will still occur on the
Scheduled Closing Date for the affected Conveyed Interests, (y) the Purchase
Price will be reduced at Closing by an amount equal to the Allocated Value of
the affected Conveyed Interests and (z) the applicable provisions herein with
respect to uncured Environmental Defects and/or Disputed Environmental Matters
will apply mutatis mutandis to the amounts placed in the Escrow Account pursuant
to Section 3.6(c) for such Conveyed Interests; provided, however, none of the
foregoing shall apply to any Subject Property that is operated by Buyer or its
Affiliates or any Subject Property in which Seller solely owns an overriding
royalty interest. Buyer shall reasonably cooperate with Seller in attempting to
cause any Third Party operator to provide Buyer with the requested access. If
any of the proposed sampling or invasive activities interfere with the normal
operations of the Subject Properties or otherwise may cause an undue risk of
harm to the site, Seller may request an appropriate modification of the proposed
sampling or invasive activities. Any sampling or invasive activities shall be
conducted by a reputable environmental consulting or engineering firm, approved
in advance by Seller (such approval not to be unreasonably withheld,
conditioned, or delayed) and, once approved, such environmental consulting or
engineering firm shall be deemed to be a “Buyer’s Representative.” Buyer shall
obtain all permits necessary to conduct any approved sampling or invasive
activities from any applicable Governmental Authorities.
(c)    Buyer shall coordinate its access rights, environmental property
assessments and physical inspections of the Subject Properties with Seller and
all Third Party operators, as applicable, to minimize any inconvenience to or
interruption of the conduct of business by Seller or any such Third Party
operator. Buyer shall abide by Seller’s, and any Third Party operator’s, safety
rules, regulations and operating policies (in each case, to the extent
communicated to Buyer) while conducting its due diligence evaluation of the
Properties, including any environmental or other inspection or assessment of the
Subject Properties and, to the extent reasonably required by any Third Party
operator, execute and deliver any access and bonding agreement required by any
such Third Party operator, in each case before conducting Buyer’s assessment on
such Subject Property in accordance with this Section 4.1. Buyer hereby defends,
indemnifies, and holds harmless each of the operators of the Subject Properties
and each Seller Indemnified Party from and against any and all Liabilities
arising out of, resulting from or relating to any field visit, environmental
assessment or other due diligence activity conducted by Buyer or any Buyer’s
Representative with respect to the Subject Properties, EVEN IF SUCH LIABILITIES
ARISE OUT OF OR RESULT FROM, IN WHOLE OR IN PART, THE SOLE, ACTIVE, PASSIVE,
CONCURRENT OR COMPARATIVE NEGLIGENCE, STRICT LIABILITY OR OTHER FAULT OF, OR THE
VIOLATION OF LAW BY, ANY SELLER INDEMNIFIED PARTY, EXCEPTING ONLY LIABILITIES TO
THE EXTENT ACTUALLY RESULTING FROM THE GROSS NEGLIGENCE

13

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

OR WILLFUL MISCONDUCT OF ANY SUCH OPERATOR OF THE SUBJECT PROPERTIES OR ANY
SELLER INDEMNIFIED PARTY; provided that Buyer’s indemnity shall not include any
Liabilities attributable to conditions or defects existing prior to such due
diligence activities (including, for the avoidance of doubt, Liabilities arising
out of, resulting from or relating to any Environmental Defects or similar
environmental matters discovered as part of a due diligence activity of Buyer or
Buyer’s Representatives) except and solely to the extent exacerbated, if at all,
as a result of such due diligence activity of Buyer or Buyer’s Representatives.
(d)    Buyer acknowledges that any entry into Seller’s offices or onto the
Subject Properties shall be at Buyer’s sole risk, cost and expense, and, subject
to the terms hereof, that none of the Seller Indemnified Parties shall be liable
in any way for any injury, loss or damage arising out of such entry that may
occur to Buyer or any of Buyer’s Representatives pursuant to this Agreement.
Buyer hereby fully waives and releases any and all Liabilities against all of
the Seller Indemnified Parties for any injury, death, loss or damage to any of
Buyer’s Representatives or their property in connection with Buyer’s due
diligence activities, EVEN IF SUCH LIABILITIES ARISE OUT OF OR RESULT FROM, IN
WHOLE OR IN PART, THE SOLE, ACTIVE, PASSIVE, CONCURRENT OR COMPARATIVE
NEGLIGENCE, STRICT LIABILITY OR OTHER FAULT OF, OR THE VIOLATION OF LAW BY, ANY
SELLER INDEMNIFIED PARTY, EXCEPTING ONLY LIABILITIES ACTUALLY RESULTING FROM THE
GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF ANY SELLER INDEMNIFIED PARTY.
(e)    Buyer agrees to promptly provide Seller, but in no event less than five
days after receipt or creation thereof by Buyer or any of Buyer’s
Representatives (including Buyer’s environmental consulting or engineering
firm), copies of all final reports and test results prepared hereunder by Buyer
and/or any of Buyer’s Representatives, which contain data collected or generated
from Buyer’s and/or any of Buyer’s Representatives’ due diligence with respect
to the Conveyed Interests, including all environmental and title reports. Seller
shall not be deemed by its or its representatives’ receipt of said documents or
otherwise to have made any representation or warranty, express, implied or
statutory, as to the condition of the Subject Properties or to the accuracy of
said documents or the information contained therein.
(f)    Upon completion of Buyer’s due diligence, Buyer shall at its sole cost
and expense and without any cost or expense to Seller or any of its Affiliates
(i) repair all damages to any Subject Properties to the extent caused by Buyer’s
and/or any of Buyer’s Representatives’ due diligence (including due diligence
conducted by Buyer’s environmental consulting or engineering firm), (ii) if
Buyer performed a Phase II ESA hereunder, restore the affected Subject
Properties to the approximate same condition as, or better condition than, they
were prior to commencement of any such Phase II ESA, and (iii) remove all
equipment, tools and other property brought onto the Subject Properties in
connection with such due diligence. Any disturbance to the Subject Properties
(including the leasehold associated therewith), to the extent resulting from
such due diligence, will be promptly corrected by Buyer at Buyer’s sole cost and
expense.
(g)    During all periods that Buyer and/or any of Buyer’s Representatives
(including Buyer’s environmental consulting or engineering firm) are on the
Subject Properties, Buyer shall maintain, at its sole cost and expense, policies
of insurance of the types and in the

14

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

amounts held by Buyer immediately prior to the Execution Date. Coverage under
all insurance required to be carried by Buyer hereunder will (i) be primary
insurance, (ii) list the Seller Indemnified Parties as additional insureds,
(iii) waive subrogation against the Seller Indemnified Parties, and (iv) provide
for 30 days’ prior written notice to Seller in the event of cancellation,
expiration, or modification of the policy or reduction in coverage. Upon request
by Seller, Buyer shall provide evidence of such insurance to Seller prior to
entering any of the Subject Properties.
4.2    Confidentiality. Buyer acknowledges that, pursuant to its right of access
to the Records or the Subject Properties, Buyer and/or Buyer’s Representatives
(including Buyer’s environmental consulting or engineering firm) will become
privy to confidential and other information of Seller and/or Seller’s Affiliates
and Buyer shall ensure that such confidential information (a) shall not be used
by Buyer and Buyer’s Representatives for any purpose other than in connection
with the transactions contemplated by this Agreement and (b) shall be held
confidential by Buyer and Buyer’s Representatives (including Buyer’s
environmental consulting or engineering firm) in accordance with the terms of
the Confidentiality Agreement. If the Closing should occur, the foregoing
confidentiality restriction on Buyer and the Confidentiality Agreement, shall
terminate as of the Closing Date (except as to (i) such portion of the Conveyed
Interests that are not conveyed to Buyer pursuant to the provisions of this
Agreement, (ii) the Excluded Assets and Other Matters, and (iii) information
related to Seller, Seller’s Affiliates, or any assets other than the Subject
Properties). Further, if the Closing should occur, the terms and conditions of
the Confidentiality Agreement will apply mutatis mutandis to Seller and its
Affiliates (as if it, and they, were the “Recipient” thereunder) for a period
equal to the initial term of the Confidentiality Agreement, it being the intent
of the Parties that Seller will treat the “Confidential Information” (as defined
therein) in strict confidence for such period after the Closing. Notwithstanding
anything contained herein to the contrary, this Section 4.2 shall not limit or
otherwise modify the confidentiality restrictions in the License Agreement.
4.3    Disclaimers.

(d)    SELLER AND BUYER AGREE THAT, TO THE EXTENT REQUIRED BY APPLICABLE LAW TO
BE EFFECTIVE, THE DISCLAIMERS OF CERTAIN REPRESENTATIONS AND WARRANTIES
CONTAINED IN THIS SECTION 4.3 ARE “CONSPICUOUS” DISCLAIMERS FOR THE PURPOSE OF
ANY APPLICABLE LAW.
ARTICLE V
TITLE MATTERS; CASUALTY; TRANSFER RESTRICTIONS
5.1    General Disclaimer of Title Warranties and Representations. Except for
the Special Warranty set forth in the Assignment and without limiting Buyer’s
remedies for Title Defects set forth in this Article V, Seller makes no warranty
or representation, express, implied, statutory or otherwise, with respect to
Seller’s title to any of the Conveyed Interests, and Buyer hereby acknowledges
and agrees that Buyer’s sole remedy for any defect of title, including any Title
Defect, with respect to Seller’s title to any of the Conveyed Interests (a)
before Closing, shall be as set forth in Section 5.3 and, if applicable,
Section 14.1(e), and (b) from and after Closing, shall be (i) with respect to
Title Defects for which the Title Defect Amount therefor comprises part of the
Defect Escrow Amount, pursuant to Sections 3.6, 5.3(d) and 5.3(j) (along with
any associated provisions in this Agreement), as applicable, in each case,
however, subject to Section 5.3(i), and (ii) in all other instances, pursuant to
the Special Warranty set forth in the Assignment and in compliance with, and
subject to, Section 5.2 below and, if applicable, any Title Indemnity Agreement.
Notwithstanding anything to the contrary, (A) the Parties acknowledge and agree
that none of Seller’s representations and warranties in Article VII will be
deemed representations or warranties with respect to Seller’s title to any of
the Conveyed Interests and, (B) for the avoidance of doubt, Buyer shall have the
right hereunder to assert Title Defects (subject to the provisions of Section
5.3) of which Buyer’s or any of its Affiliates’ employees, title attorneys,
landmen or other title examiners were aware prior to the Execution Date
(including matters with respect to the partial releases referenced in
Section 5.2(a)(ii), with respect to which, Seller shall promptly provide Buyer,
upon Buyer’s request during the Interim Period, with copies of, or access to,
any such releases in Seller’s or its Affiliates’ possession for purposes of
Buyer completing its title diligence pursuant to Section 5.3).
5.2    Special Warranty.
(a)    Special Warranty of Title. If Closing occurs, then the Assignment shall
contain a special warranty of title whereby Seller shall, until the end of the
Survival Period, warrant Defensible Title, without duplication, to the Leases
set forth on Exhibit A (limited to the Eagle Ford Formation) and to the Wells
set forth in Exhibit B (limited to the currently producing formation for

17

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

each such Well), unto Buyer against every Person whomsoever lawfully claiming or
to claim the same or any part thereof by, through or under Seller, but not
otherwise, subject, however, to the Permitted Encumbrances (the “Special
Warranty”); provided, however, that, (i) except with respect to any liability of
Seller for any claim asserted in writing by Buyer to Seller in accordance with
this Section 5.2 and the Assignment before the expiration of the Survival Period
for breach of the Special Warranty, the Special Warranty shall cease and
terminate at the end of the Survival Period, and (ii) notwithstanding anything
in this Agreement to the contrary, Seller’s release of any depths covered by a
Lease pursuant to a partial release of that Lease (including any Third Party
claims with respect to those depths released) shall not constitute a breach of
the Special Warranty. The Special Warranty shall be subject to the further
limitations and provisions of this Section 5.2.
(b)    Recovery on Special Warranty.
(i)    Buyer’s Assertion of Special Warranty Breaches. Prior to the expiration
of the period of time commencing as of the Closing Date and ending at 5:00 p.m.
(Central Time) on the fourth anniversary thereof (the “Survival Period”), Buyer
shall be entitled to furnish Seller a Title Defect Notice meeting the
requirements of Section 5.3(a) setting forth any and all matters which Buyer
intends to assert as a breach of the Special Warranty (collectively, the
“Special Warranty Notices” and, individually, a “Special Warranty Notice”).
Seller shall have a reasonable opportunity, but not the obligation, to cure any
breach of the Special Warranty asserted by Buyer pursuant to this
Section 5.2(b). Buyer shall reasonably cooperate with any attempt by Seller to
cure any such breach. For all purposes of this Agreement, Buyer shall be deemed
to have waived, and Seller shall have no further liability for, any breach of
the Special Warranty that Buyer fails to assert by a Special Warranty Notice
given to Seller before the expiration of the Survival Period.
(ii)    Limitations on Special Warranty. Recovery by Buyer for any breach by
Seller of the Special Warranty shall be limited to an amount (without any
interest accruing thereon) equal to the reduction to the Purchase Price to which
Buyer would have been entitled had Buyer asserted the defect giving rise to such
breach of the Special Warranty as a Title Defect prior to the Title Defect Claim
Date pursuant to Section 5.3 and taking into account the last sentence of this
Section 5.2(b)(ii), and in no event shall that recovery (together with any other
Title Defect recoveries and Purchase Price adjustments with respect to such
Conveyed Interest) exceed the Allocated Value of the affected Conveyed Interest.
The Individual Title Defect Threshold and Aggregate Deductible shall not apply
to any recovery for any breach by Seller of the Special Warranty, and Buyer
shall not be entitled to recover any amount for any breach of the Special
Warranty to the extent that the Purchase Price is or has been reduced for the
same Title Defect pursuant to Section 5.3(d)(i).
5.3    Notice of Title Defects; Defect Adjustments.
(a)    Title Defect Notices. Prior to the Title Defect Claim Date, Buyer must
deliver claim notices to Seller meeting the requirements of this Section 5.3(a)
(collectively, the “Title Defect Notices” and, individually, a “Title Defect
Notice”) setting forth any matters which, in Buyer’s reasonable opinion,
constitute Title Defects and which Buyer intends to assert as a Title Defect
pursuant to this Section 5.3(a). For all purposes of this Agreement and
notwithstanding anything herein to the contrary, Buyer shall be deemed to have
waived, and Seller shall have no liability for,

18

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

any Title Defect which Buyer fails to assert as a Title Defect by a properly
delivered Title Defect Notice received by Seller before the Title Defect Claim
Date; provided, however, that, for purposes of the Special Warranty, such waiver
shall not apply to any matter that, prior to the Title Defect Claim Date, is not
discovered by any of Buyer’s or any of its Affiliates’ employees, title
attorneys, landmen or other title examiners while conducting Buyer’s due
diligence with respect to the Conveyed Interests that in Buyer’s reasonable
opinion constitutes a breach by Seller of the Special Warranty. To be effective,
each Title Defect Notice shall be in writing, and shall include (i) a
description of the alleged Title Defect and the individual Well or Lease
affected by the alleged Title Defect (each such Conveyed Interest, a “Title
Defect Property”), (ii) the Allocated Value of the Title Defect Property, (iii)
supporting documents reasonably necessary for Seller to verify the existence of
the alleged Title Defect with respect to the Title Defect Property (any and all
of which supporting documents may be furnished via access to a web link or ftp
site (in lieu of other means of delivery)), and (iv) the amount by which Buyer
reasonably believes the Allocated Value of the Title Defect Property is reduced
by such alleged Title Defect and the computations upon which Buyer’s belief is
based, in each case, in accordance with Section 5.3(g). Notwithstanding anything
contained in this Agreement to the contrary, and for the avoidance of doubt, any
Title Defect asserted by Buyer pursuant to this Section 5.3(a) and any breach of
the Special Warranty asserted by Buyer pursuant to Section 5.2(b) shall be
limited to the Leases set forth on Exhibit A (as to the Eagle Ford Formation
only) and the Wells set forth on Exhibit B (as to the currently producing
formation for each such Well) and Buyer shall not have the right to assert Title
Defects or breach of the Special Warranty with respect to any other depths or
formations or any other Conveyed Interests. To give Seller an opportunity to
commence reviewing and curing Title Defects, Buyer agrees to use reasonable
efforts to give Seller, on or before the end of each calendar week prior to the
Title Defect Claim Date, written notice of all alleged Title Defects (as well as
any claims that would be claims under the Special Warranty) discovered by Buyer
during the preceding calendar week, which notice may be preliminary in nature
and supplemented prior to the Title Defect Claim Date.
(b)    Title Benefit Notices. Seller shall have the right, but not the
obligation, to deliver to Buyer on or before the Title Defect Claim Date, with
respect to each Title Benefit which it discovers after the Execution Date, a
notice (a “Title Benefit Notice”) including (i) a description of the alleged
Title Benefit and the individual Well or Lease, or portion thereof, affected by
such alleged Title Benefit (each such Conveyed Interest, a “Title Benefit
Property”), and (ii) with respect to each Title Benefit Property, the amount by
which Seller reasonably believes the Allocated Value of such Title Benefit
Property is increased by such alleged Title Benefit, and the computations upon
which Seller’s belief is based. Seller shall be deemed to have waived any Title
Benefit which Seller fails to assert as a Title Benefit by a Title Benefit
Notice delivered to Buyer on or before the Title Defect Claim Date.
(c)    Seller’s Right to Cure. Seller shall have the right, but not the
obligation, to attempt, at its sole cost, to cure any Title Defects timely and
properly alleged under Section 5.3(a) at any time prior to 5:00 p.m. Central
Time on the date that is 45 days after the Closing Date (the “Cure Period”),
provided that Seller has notified Buyer under Section 5.3(d)(i) of its election
to cure such Title Defects no later than the sixth Business Day prior to
Closing. During the period of time from Closing to the expiration of the Cure
Period, Buyer agrees to afford Seller and its officers, employees and other
authorized representatives reasonable access, during normal business hours,

19

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

to the Subject Properties and all Records in Buyer’s or any of its Affiliates’
possession in order to facilitate Seller’s attempt to cure any such Title
Defects (and if Seller and/or its representatives access the Subject Properties
in connection with such right to cure, the provisions herein setting forth the
terms and conditions of Buyer’s (and Buyer’s Representatives’) access to the
Subject Properties and the Records prior to the Closing will, notwithstanding
anything to the contrary, apply mutatis mutandis to Seller and its
representatives). An election by Seller to attempt to cure a Title Defect shall
be without prejudice to its rights under Section 5.3(j) and shall not constitute
an admission against interest or a waiver of Seller’s right to dispute the
existence, nature or value of, or cost to cure, the alleged Title Defect.
(d)    Remedies for Title Defects. Subject to Seller’s continuing right to
dispute the existence of a Title Defect and/or the Title Defect Amount asserted
with respect thereto as described in Section 5.3(j), and subject to the rights
of the Parties pursuant to Section 14.1(e), in the event that any Title Defect
timely and properly asserted by Buyer in accordance with Section 5.3(a) is not
waived in writing by Buyer or cured on or before the sixth Business Day prior to
Closing, Seller shall, at its sole option, elect to:
(i)    subject to Section 5.3(i), assign the Title Defect Property to Buyer at
Closing and reduce the Purchase Price at Closing by the Title Defect Amount
determined pursuant to Section 5.3(g) (as asserted by Buyer in good faith as
part of a Title Defect Notice timely and properly alleged under Section 5.3(a)),
provided that Seller will have the right for the Cure Period (in accordance with
Section 5.3(c)) to cure the Title Defect relating to such assigned Title Defect
Property, and should Seller cure such Title Defect, then such cure will be taken
into account in the Final Settlement Statement delivered pursuant to Section
3.6; or
(ii)    subject to Section 5.3(i), with Buyer’s consent, at its sole option,
indemnify Buyer against all Liability (up to the Allocated Value of the
applicable Title Defect Property and subject to the Individual Title Defect
Threshold and the Aggregate Deductible) resulting from such Title Defect with
respect to such Title Defect Property pursuant to an indemnity agreement
prepared by Seller in a form and substance reasonably acceptable to Buyer (a
“Title Indemnity Agreement”);
provided that, subject to Section 5.3(i), with respect to any Title Defect
(including the Title Defect Amount with respect to such Title Defect) that the
Parties have not agreed upon prior to the sixth Business Day prior to Closing,
the Title Defect Property for said Title Defect will be included with the
Conveyed Interests conveyed to Buyer at Closing and the Purchase Price will be
reduced at Closing by the asserted Title Defect Amount (as asserted by Buyer in
good faith as part of a Title Defect Notice timely and properly alleged under
Section 5.3(a)) of the Title Defect Property affected by such Title Defect; and,
provided, further, that the Final Price shall be adjusted to take into account
the resolution of all Title Disputes after Closing (either by agreement of the
Parties or as a result of the determination of the Title Arbitrator under
Section 5.3(j)), any Title Defects cured by Seller during the Cure Period, and
the application of Section 5.3(i).
(e)    Remedies for Title Benefits. With respect to each Title Benefit Property
timely and properly reported under Section 5.3(b), Buyer shall notify Seller in
writing on or before the date that is six Business Days prior to Closing whether
Buyer (i) concedes the Title Benefit

20

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

asserted therein, or (ii) disputes such Title Benefit, in which case such Title
Benefit shall be deemed to be a Title Dispute and the provisions of Section
5.3(j) shall apply. For the avoidance of doubt, Title Benefits Amounts shall in
no event increase the Purchase Price and will only be used to offset Title
Defect Amounts hereunder.
(f)    Exclusive Remedy. Except for Buyer’s rights under the Special Warranty
and Buyer’s right to terminate this Agreement pursuant to Section 14.1(e), (i)
Section 5.3(d) shall be the exclusive right and remedy of Buyer with respect to
Seller’s failure to have Defensible Title with respect to any Lease or Well, or
any other title matter with respect to any Subject Property, and (ii) Buyer
hereby waives any and all other rights or remedies with respect thereto.
(g)    Title Defect Amount. The amount by which the Allocated Value of a Title
Defect Property is reduced as a result of the existence of a Title Defect shall
be the “Title Defect Amount” for such Title Defect Property and shall be
determined in accordance with the following terms and conditions (without
duplication):
(i)    if Buyer and Seller agree on the Title Defect Amount, then that amount
shall be the Title Defect Amount;
(ii)    if the Title Defect with respect to such Title Defect Property is an
Encumbrance that is undisputed and liquidated in amount, then the Title Defect
Amount shall be the amount necessary to be paid to remove the Title Defect from
such Title Defect Property;
(iii)    if the Title Defect with respect to such Title Defect Property
represents a decrease of (A) Seller’s Net Revenue Interest for such Title Defect
Property such that Seller’s Net Revenue Interest for such Title Defect Property
is less than (B) the Net Revenue Interest set forth for such Title Defect
Property on Exhibit A or Exhibit B, as applicable, 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 Net Revenue Interest
decrease and the denominator of which is the Net Revenue Interest set forth for
such Title Defect Property on Exhibit A or Exhibit B, as applicable;
(iv)    if the Title Defect with respect to such Title Defect Property
represents an increase of (A) Seller’s Working Interest for such Title Defect
Property such that Seller’s Working Interest for such Title Defect Property is
in excess of (B) the Working Interest set forth for such Title Defect Property
on Exhibit B by not more than 10% (on an 8/8ths basis), without any increase of
Seller’s Net Revenue Interest for such Title Defect Property, 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 Working
Interest increase and the denominator of which is the Working Interest set forth
for such Title Defect Property on Exhibit B;
(v)    if the Title Defect with respect to such Title Defect Property represents
a discrepancy where (A) the actual Net Acres for such Title Defect Property is
less than (B) the Net Acres set forth on Exhibit A for such Title Defect
Property, then the Title Defect Amount shall be the product obtained by
multiplying such Net Acre decrease by the Allocated Value (on a per Net Acre
dollar amount basis) for such Title Defect Property;

21

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

(vi)    if the Title Defect represents an obligation or Encumbrance upon or
other defect in title to the Title Defect Property of a type not described
above, then 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, the values placed upon the Title Defect by Buyer and
Seller and such other reasonable factors as are necessary to make a proper
evaluation; provided, however, that if such Title Defect is reasonably capable
of being cured, the Title Defect Amount shall not be greater than the Allocated
Value of the Title Defect Property;
(vii)    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
(viii)    notwithstanding anything to the contrary in this Article V, the
aggregate Title Defect Amounts attributable to the effects of all Title Defects
upon any Title Defect Property shall not exceed the Allocated Value of such
Title Defect Property;
provided, however, that, notwithstanding the foregoing, if a Title Defect (other
than a Title Defect affecting a Title Defect Property in which Seller only owns
an overriding royalty interest) results in the Seller’s Net Revenue Interest in
any Well or Lease being equal to or less than 70% (proportionately reduced based
on Seller’s Working Interest therein), the Title Defect Amount with respect to
such Well or Lease shall be determined in accordance with Section 5.3(g)(vi),
rather than Section 5.3(g)(iii).
(h)    Title Benefit Amount. The Title Benefit Amount resulting from a Title
Benefit shall be determined in accordance with the following methodology, terms
and conditions (without duplication):
(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 with respect to a Title Benefit Property represents
an increase of (A) Seller’s Net Revenue Interest for any Title Benefit Property
such that Seller’s Net Revenue Interest for such Title Benefit Property is
greater than (B) the Net Revenue Interest set forth for such Title Benefit
Property on Exhibit A or Exhibit B, without any increase of Seller’s Working
Interest for such Title Defect Property, 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 Net Revenue Interest increase and the
denominator of which is the Net Revenue Interest set forth for such Title
Benefit Property on Exhibit A or Exhibit B;
(iii)    if the Title Benefit with respect to a Title Benefit Property
represents a discrepancy where (A) the actual Net Acres for such Title Defect
Property is greater than (B) the Net Acres set forth on Exhibit A for such Title
Benefit Property, then the Title Benefit Amount shall be the product obtained by
multiplying such Net Acre increase by the Allocated Value (on a per Net Acre
dollar amount basis) for such Title Benefit Property; and

22

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

(iv)    if the Title Benefit is of a type not described above (including, for
the avoidance of doubt, the circumstances where a Title Benefit affects a
portion, but not the entirety of any Well or Lease), 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, the values placed upon the Title Benefit by Buyer and Seller and such
other reasonable factors as are necessary to make a proper evaluation.
(i)    Title Defect Threshold and Deductible. Notwithstanding anything herein to
the contrary, except as otherwise provided in the last sentence of this Section
5.3(i), with respect to any Title Defect timely and properly asserted under
Section 5.3(a), (A) in no event shall there be any adjustments to the Purchase
Price or other remedies provided by Seller hereunder for any Title Defect with
respect to a Title Defect Property (or Title Defects, if more than one Title
Defect affects the Title Defect Property) for which the Title Defect Amount (or
aggregate Title Defect Amount(s) of the Title Defects affecting the Title Defect
Property, if applicable), in each case, does not exceed the lesser of (x)
$40,000 and (y) 75% of the Allocated Value of the relevant Title Defect Property
(such lesser amount, the “Individual Title Defect Threshold”); and (B) in no
event shall there be any adjustment to the Purchase Price or other remedies
provided by Seller hereunder for any Title Defect with respect to a Title Defect
Property for which the Title Defect Amount (or Title Defect Amounts, if
applicable) exceeds the Individual Title Defect Threshold unless (1) the amount
of the sum of (I) (x) the aggregate Title Defect Amounts of all such Title
Defects that exceed the Individual Title Defect Threshold (as determined in
accordance with (A) above, but excluding any Title Defect Amounts attributable
to Title Defects cured by Seller) less (y) the aggregate Title Benefit Amount of
all Title Benefits, plus (II) the aggregate Remediation Amounts of all
Environmental Defects that exceed the Individual Environmental Threshold (as
determined in accordance with Section 6.1(e), but excluding any Remediation
Amounts attributable to Conveyed Interests subject to Environmental Defects that
are retained by Seller pursuant to Section 6.1(c) and any Environmental Defects
cured by Seller), exceeds (2) the Aggregate Deductible, after which point Buyer
shall be entitled to adjustments to the Purchase Price or other applicable
remedies available hereunder, but only to the extent that the amount by which
the aggregate amount of such Title Defect Amounts and Remediation Amounts
exceeds the Aggregate Deductible. For the avoidance of doubt, a Title Defect
Property shall refer to the individual Lease or Well affected by a Title Defect
and, if a Title Defect affects both a Lease and a Well (or multiple Leases or
Wells), the Title Defect Amounts with respect to such Title Defects shall not be
aggregated when determining whether the Individual Title Defect Threshold has
been satisfied. Notwithstanding the foregoing, the Individual Title Defect
Threshold and the Aggregate Deductible shall not apply to any Title Defect
timely and properly asserted under Section 5.3(a) with respect to any of the
Leases set forth on Schedule 5.3(i).
(j)    Title Dispute Resolution. Seller and Buyer shall attempt to agree on
matters regarding (i) all Title Defects, Title Benefits, Title Defect Amounts
and Title Benefit Amounts, and (ii) the adequacy of any curative materials
provided by Seller to cure any alleged Title Defect (collectively “Title
Disputes”) prior to the Dispute Date. If Seller and Buyer are unable to agree by
the Dispute Date, the Title Disputes shall be exclusively and finally resolved
pursuant to this Section 5.3(j). There shall be a single arbitrator, who shall
be a title attorney with at least 10 years’ experience in oil and gas titles
involving properties in the regional area in which the Conveyed

23

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

Interests are located, as selected by the mutual agreement of Buyer and Seller
within 15 days after the Dispute Date (the “Title Arbitrator”). If the Parties
do not mutually agree upon the Title Arbitrator in accordance with this Section
5.3(j), the Dallas, Texas office of the AAA shall appoint the Title Arbitrator
under such conditions as the AAA in its sole discretion deems necessary or
advisable. The place of arbitration shall be Dallas, 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 5.3(j). Each of Buyer and Seller
shall submit to the Title Arbitrator, with a simultaneous copy to the other
Party, its proposed resolution of the applicable Title Dispute no later than 10
Business Days after the appointment of the Title Arbitrator pursuant to this
Section 5.3(j). The proposed resolution of the applicable Title Dispute shall
include the best offer of the submitting Party in a single monetary amount that
such Party is willing to pay or accept (as applicable) to settle the applicable
Title Dispute. The Title Arbitrator’s determination shall be made within 20 days
after the end of such 10 Business Day period after the submission of the Title
Disputes and shall be final and binding upon both Parties, without right of
appeal. In making his determination, the Title Arbitrator shall make a
determination of the Title Disputes submitted based solely on the single written
submission of Seller and Buyer (and without any additional or supplemental
submittals by any Party, except to the extent the Title Arbitrator requests
additional information from either Party), shall be bound by the rules set forth
in this Section 5.3 and, subject to the foregoing, may consider such other
matters as, in the opinion of the Title Arbitrator, are necessary to make a
proper determination. The Title Arbitrator, however, may not award Buyer a
greater Title Defect Amount than the Title Defect Amount claimed by Buyer in its
applicable Title Defect Notice or a lesser Title Defect Amount than the Title
Defect Amount stated by Seller in its applicable position statement delivered to
the Title Arbitrator; or, in the case of Title Benefits, a greater Title Benefit
Amount than that claimed by Seller in its applicable Title Benefit Notice or a
lesser Title Benefit Amount that claimed by Buyer in its applicable position
statement delivered to the Title Arbitrator. The Title Arbitrator shall act as
an expert 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 matter except as otherwise provided in the
following sentence. The costs of the Title Arbitrator (and the AAA, if
applicable) and the reasonable legal costs and expenses incurred by the Parties
in connection with the arbitration shall be borne pro rata between the Parties
with each Party being responsible for such costs and expenses to the extent the
Title Arbitrator has not selected such Party’s position on an aggregate dollar
basis with respect to all amounts submitted for resolution by the Title
Arbitrator.
5.4    Casualty or Condemnation Loss.
(a)    Notwithstanding anything herein to the contrary, but without prejudice to
Buyer’s rights and remedies under Section 13.2(a) (with respect to a breach of
Section 7.8 or Section 7.18), Section 13.2(b) (with respect to a breach of
Section 9.1), and/or Section 13.2(c) (with respect to the Specified Obligations
described in clause (v) of Section 13.1(b)), in each case, to the limited extent
expressly set forth in such Sections, from and after the Effective Time, if
Closing occurs, Buyer shall assume all risk of loss with respect to production
of Hydrocarbons through normal depletion (including watering out of any well,
collapsed casing or sand infiltration of any well) and the depreciation of
Conveyed Interests due to ordinary wear and tear, in each case, with respect to

24

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

the Conveyed Interests, and Buyer shall not assert such matters as Casualty
Losses or Title Defects hereunder.
(b)    If, after the Execution Date but prior to the Closing Date, any portion
of the Conveyed Interests is damaged or destroyed by fire or other casualty or
is taken in condemnation or under right of eminent domain (each, a “Casualty
Loss”) (excluding any of the Conveyed Interests affected by a Casualty Loss
that, prior to Closing, Seller has (y) replaced with property of an equivalent
or better condition and/or (z) repaired to an equivalent or better condition, in
each case, as of the Effective Time), and the Closing thereafter occurs, (i) if
such Casualty Losses exceed, in the aggregate, $2,000,000, there will be a
downward adjustment to the Purchase Price in the amount of such Casualty Losses
or (ii) if such Casualty Losses do not exceed, in the aggregate, $2,000,000,
Seller, at Closing, shall pay to Buyer all sums actually paid to Seller by Third
Parties by reason of any Casualty Loss insofar as with respect to the Conveyed
Interests and shall assign, transfer and set over to Buyer or subrogate Buyer to
all of Seller’s or its Affiliates right, title and interest (if any) in
insurance claims, unpaid awards, and other rights against Third Parties
(excluding any Liabilities, other than insurance claims, of or against any
Seller Indemnified Party) arising out of such Casualty Loss insofar as with
respect to the Conveyed Interests; provided, however, that in the event that, at
Closing, clause (i) above is applicable as a result of Casualty Losses occurring
during the Interim Period, Seller shall reserve and retain (and Buyer shall
assign to Seller) all right, title, and interest in and to such insurance
claims, unpaid awards, other rights against Third Parties, and sums paid to
Seller by Third Parties; provided, further, that, in all cases, Seller shall
reserve and retain (and Buyer shall assign to Seller) all right, title, interest
and claims against Third Parties for the recovery of Seller’s costs and expenses
incurred prior to Closing in repairing such Casualty Loss and/or pursuing or
asserting any such insurance claims or other rights against Third Parties.
5.5    Preferential Purchase Rights and Consents to Assign.
(a)    With respect to each Preferential Purchase Right set forth on
Schedule 7.9, not later than 10 days after the Execution Date (and, with respect
to each Preferential Purchase Right that is not set forth on Schedule 7.9 but is
discovered by either Party after the Execution Date and before the Closing Date,
not later than 10 days after the discovery thereof), 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 Preferential Purchase Right.
(i)    If, prior to Closing, any holder of a Preferential Purchase Right
notifies Seller that it intends to consummate the purchase of the Conveyed
Interests to which its Preferential Purchase Right applies, then the Conveyed
Interest subject to such Preferential Purchase Right shall be excluded from the
Conveyed Interests to be assigned to Buyer at Closing (but only to the extent of
the portion of such Conveyed Interest affected by the Preferential Purchase
Right), and the Purchase Price shall be reduced by the Allocated Value of the
Conveyed Interest (or portion thereof) so excluded. Seller shall be entitled to
all proceeds paid by any Person exercising a Preferential Purchase Right prior
to Closing. If, on or before 90 days following the Closing Date, such holder of
such Preferential Purchase Right fails to consummate the purchase of the
Conveyed Interest (or portion thereof) covered by such Preferential Purchase
Right (on the same terms and

25

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

conditions hereof) then (A) Seller shall so notify Buyer, (B) Buyer shall
purchase, on or before 5 Business Days following receipt of such notice, such
Conveyed Interest (or portion thereof) that was so excluded from the Conveyed
Interests to be assigned to Buyer at Closing, under the terms of this Agreement
and for a price equal to the amount by which the Purchase Price was reduced at
Closing with respect to such excluded Conveyed Interest (or portion thereof) (as
such amount is appropriately adjusted in accordance with the other terms of this
Agreement) and (C) Seller shall assign to Buyer the Conveyed Interest (or
portion thereof) so excluded at Closing pursuant to an instrument in
substantially the same form as the Assignment.
(ii)    All Conveyed Interests 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 without exercise by the holder thereof,
in each case, prior to Closing, shall be sold to Buyer at Closing pursuant to
the provisions of this Agreement. If, as of Closing, the time for exercising a
Preferential Purchase Right has not expired and such Preferential Purchase Right
has not been exercised or waived, then the Conveyed Interest subject to such
Preferential Purchase Right shall be included in the Conveyed Interests to be
assigned to Buyer at Closing, and Buyer shall be solely responsible for
complying with the terms of such Preferential Purchase Right and shall be
entitled to the proceeds, if any, associated with the exercise of such
Preferential Purchase Right.
(b)    With respect to each Consent set forth on Schedule 7.4, Seller, not later
than 10 days after the Execution Date (and, with respect to each Consent that is
not set forth on Schedule 7.4 but is discovered by either Party after the
Execution Date and before the Closing Date, not later than 10 days after the
discovery thereof), shall send to the holder of each such Consent a notice in
material compliance with the contractual provisions applicable to such Consent
seeking such holder’s consent to the transactions contemplated hereby.
(i)    If Seller fails to obtain a Consent set forth in Schedule 7.4 (or any
Consent that is not set forth in Schedule 7.4 but is discovered by either Party
after the Execution Date and before the Closing Date) prior to Closing and the
failure to obtain such Consent would cause (A) the assignment of the Conveyed
Interests affected thereby to Buyer to be void or nullified, (B) the termination
of a Lease or an Applicable Contract, or (C) the assessment of a payment, fine
or monetary penalty, in each case, pursuant to the express terms of the Lease,
Applicable Contract, or other instrument requiring such Consent, as the case may
be (each, a “Required Consent”), then, in each case, the Conveyed Interest (or
portion thereof) subject to such un‑obtained Consent and any associated Conveyed
Interests shall be excluded from the Conveyed Interests to be assigned to Buyer
at Closing, and the Purchase Price shall be reduced by the Allocated Value of
such Conveyed Interest (or portion thereof) and such associated Conveyed
Interests so excluded. In the event that a Required Consent (with respect to a
Conveyed Interest excluded pursuant to this Section 5.5(b)(i)) that was not
obtained prior to Closing is obtained within 180 days following Closing, then,
within 10 Business Days after such Consent is obtained (x) Buyer shall purchase
the Conveyed Interest (or portion thereof) and any associated Conveyed Interests
that were so excluded as a result of such previously un‑obtained Consent and pay
to Seller the amount by which the Purchase Price was reduced at Closing with
respect to the Conveyed Interest (or portion thereof) and any associated
Conveyed Interests so excluded (as such amount is appropriately adjusted in
accordance with the

26

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

other terms of this Agreement) and (y) Seller shall assign to Buyer the Conveyed
Interest (or portion thereof) and any associated Conveyed Interests so excluded
at Closing pursuant to an instrument in substantially the same form as the
Assignment.
(ii)    Notwithstanding anything in this Agreement to the contrary, but without
prejudice to Buyer’s rights and remedies under Sections 13.2 and/or 14.1(d) (in
each case, as to breaches of this Section 5.5(b) or Section 7.4), if Seller
fails to obtain a Consent other than a Required Consent, then the Conveyed
Interest (or portion thereof) subject to such un‑obtained Consent shall
nevertheless be assigned by Seller to Buyer at Closing as part of the Conveyed
Interests and, Buyer shall have no claim against Seller, and Seller shall have
no Liability, for the failure to obtain such Consent.
(iii)    Prior to Closing, Seller and Buyer shall use their commercially
reasonable efforts to obtain all Consents listed on Schedule 7.4 (and any
Required Consent that is not set forth in Schedule 7.4 but is discovered by
either Party after the Execution Date and before the Closing Date); provided,
however, that neither Party shall be required to incur any Liability or pay any
money in order to obtain any such Consent (unless Buyer elects to pay for or
reimburse Seller for any such Liability or payment of monies). Subject to the
foregoing, Buyer agrees to provide Seller with any information or documentation
that may be reasonably requested by Seller and/or the Third Party holder(s) of
such Consents, including evidence of financial capability and bonding, in order
to facilitate the process of obtaining such Consents.
ARTICLE VI
ENVIRONMENTAL MATTERS
6.1    Environmental Defects.

27

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

(a)    Assertions of Environmental Defects. Buyer must deliver claim notices to
Seller meeting the requirements of this Section 6.1(a) (collectively the
“Environmental Defect Notices” and individually an “Environmental Defect
Notice”) not later than the Environmental Defect Claim Date setting forth any
matters which, in Buyer’s reasonable opinion, constitute Environmental Defects
and which Buyer intends to assert as Environmental Defects pursuant to this
Section 6.1. Except for, and without prejudice to, Buyer’s right to
indemnification pursuant to (w) Section 13.2(a) (with respect to a breach by
Seller of Section 7.15), (x) Section 13.2(b) (with respect to a breach by Seller
of Section 9.1), (y) Section 13.2(d)(i) and/or (z) Section 13.2(d)(ii) (in each
case to the limited extent expressly set forth in such Sections), Buyer shall be
deemed to have waived, and Seller shall have no liability for, any Environmental
Defect which Buyer fails to assert as an Environmental Defect by a properly
delivered Environmental Defect Notice received by Seller, before the
Environmental Defect Claim Date, with such liabilities being “Buyer’s
Environmental Liabilities.” To be effective, each Environmental Defect Notice
shall be in writing and shall include (i) a description of the matter
constituting the alleged Environmental Condition (including the applicable
Environmental Law violated or implicated thereby) and the Conveyed Interests
affected by such alleged Environmental Condition (each, an “Environmental Defect
Property”), (ii) the Allocated Value of each Environmental Defect Property (or
portions thereof) affected by such alleged Environmental Condition, (iii)
supporting documents reasonably necessary for Seller to verify the existence of
such alleged Environmental Condition (any and all of which supporting documents
may be furnished via access to a web link or ftp site (in lieu of other means of
delivery)), and (iv) a calculation of the Remediation Amount (itemized in
reasonable detail) that Buyer asserts is attributable to such alleged
Environmental Condition with respect to each Environmental Defect Property.
Buyer’s calculation of the Remediation Amount included in the Environmental
Defect Notice must describe in reasonable detail the Remediation proposed for
the alleged 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. Seller shall have the right, but not the
obligation, to cure any asserted Environmental Defect at any time prior to the
expiration of the Cure Period, provided that Seller has notified Buyer under
Section 6.1(c)(i) of its election to cure such Environmental Defects no later
than the sixth Business Day prior to Closing. During the period of time from
Closing to the expiration of the Cure Period, Buyer agrees to afford Seller and
its officers, employees, and other authorized representatives reasonable access,
during normal business hours, to the Subject Properties and all Records in
Buyer’s or any of its Affiliates’ possession in order to facilitate Seller’s
attempt to cure any Environmental Defects, and if Seller and/or its
representatives access the Subject Properties in connection with such right to
cure, the provisions herein setting forth the terms and conditions of Buyer’s
(and Buyer’s Representatives’) access to the Subject Properties prior to the
Closing will, notwithstanding anything to the contrary, apply mutatis mutandis
to Seller and its representatives. To give Seller an opportunity to commence
reviewing and curing Environmental Defects, Buyer agrees to use reasonable
efforts to give Seller, on or before the end of each calendar week prior to the
Environmental Defect Claim Date, written notice of all alleged Environmental
Defects discovered by Buyer during the preceding calendar week, which notice may
be preliminary in nature and supplemented prior to the Environmental Defect
Claim Date.

28

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

(c)    Remedies for Environmental Defects. Subject to Seller’s continuing right
to dispute the existence of an Environmental Defect and/or the Remediation
Amount asserted with respect thereto as described in Section 6.1(f), and subject
to the rights of the Parties pursuant to Section 14.1(e), in the event that any
Environmental Defect timely and properly asserted by Buyer in accordance with
Section 6.1(a) is not waived in writing by Buyer or cured on or before the sixth
Business Day prior to Closing, Seller shall, at its sole option, elect to:
(i)    subject to Section 6.1(e), assign the Environmental Defect Property to
Buyer at Closing and reduce the Purchase Price at Closing by the Remediation
Amount, provided that Seller will have the right until the expiration of the
Cure Period (in accordance with Section 6.1(b)) to cure the Environmental Defect
relating to such assigned Environmental Defect Property, and should Seller cure
such Environmental Defect, then such cure will be taken into account in the
Final Settlement Statement delivered pursuant to Section 3.6;
(ii)    retain the entirety of the Environmental Defect Property, in which event
the Environmental Defect Property will be excluded from the Conveyed Interests
at Closing and the Purchase Price shall be reduced at Closing by an amount equal
to the Allocated Value of such Environmental Defect Property; or
(iii)    subject to Section 6.1(e), with Buyer’s consent, at its sole option,
indemnify Buyer against all Liability resulting from such Environmental Defect
with respect to the Conveyed Interests pursuant to an indemnity agreement
prepared by Seller in a form and substance reasonably acceptable to Buyer (each,
an “Environmental Indemnity Agreement”);
provided that, subject to Section 6.1(e), if the Remediation Amount (as asserted
by Buyer in good faith as part of an Environmental Defect Notice that is timely
and properly asserted pursuant to Section 6.1(a)) for any Environmental Defect
Property exceeds the greater of (1) $150,000 and (2) the Allocated Value of the
Environmental Defect Property, and such Environmental Defect is not waived in
writing by Buyer or cured during the Cure Period, either Party may, at its sole
option, elect to exclude the Environmental Defect Property from the Conveyed
Interests by delivering a notice to the other Party, in which event Buyer shall
promptly assign to Seller such Conveyed Interests, such Conveyed Interests will
constitute Excluded Assets and Other Matters, and the Purchase Price shall be
reduced by an amount equal to the Allocated Value of such Environmental Defect
(which adjustment shall be taken into account in the Final Settlement
Statement); provided, however, that any such assignment to Seller shall not take
place until such time as a determination can be made under Section 6.1(e) as to
whether an adjustment to the Purchase Price or other remedies provided by Seller
(including the Parties’ ability to elect to exclude an Environmental Defect
Property as set forth above) are available to Buyer after application of Section
6.1(e), and in the event that after application of Section 6.1(e), no Purchase
Price adjustment or other remedies provided by Seller are available to Buyer,
Buyer shall retain the Environmental Defect Property and it shall remain part of
the Conveyed Interests, notwithstanding any election to exclude the
Environmental Defect Property by either Party. Subject to Section 6.1(e), with
respect to any Environmental Defect (including the Remediation Amount with
respect to such Environmental Defect) that the Parties’ have not agreed upon
prior to the sixth Business Day prior to Closing, the Environmental Defect
Property for said Environmental Defect will be included with the Conveyed

29

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

Interests conveyed to Buyer at Closing and the Purchase Price will be reduced at
Closing by the asserted Remediation Amount (as asserted by Buyer in good faith
as part of an Environmental Defect Notice timely and properly alleged under
Section 6.1(a)) of the Environmental Defect Property affected by such
Environmental Defect; and, provided, further, that the Final Price shall be
adjusted to take into account the resolution of all Disputed Environmental
Matters after Closing (either by agreement of the Parties or as a result of the
determination of the Environmental Arbitrator under Section 6.1(f)), any
Environmental Defects cured by Seller during the Cure Period, and the
application of Section 6.1(e). If, at the time at which the Final Price is
finally determined, the Purchase Price is reduced by the Remediation Amount for
any Environmental Defect (except for Environmental Defect Properties excluded
pursuant to Section (c)(ii) or as set forth above, which will constitute
Excluded Assets and Other Matters) or the Purchase Price is not reduced for any
Environmental Defect as a result of the application of Section 6.1(e), Buyer
shall be deemed to have assumed responsibility for all of the costs and expenses
attributable to the Remediation of the Environmental Condition attributable to
such Environmental Defect and for all Liabilities with respect thereto and
Buyer’s obligations with respect to the foregoing shall be deemed to constitute
Assumed Obligations; provided that the foregoing shall not prejudice Buyer’s
rights under (A) any Environmental Indemnity Agreement and/or (B) (1) Section
13.2(a) (with respect to a breach by Seller of Section 7.15), (2) Section
13.2(b) (with respect to a breach by Seller of Section 9.1), (3) Section
13.2(d)(i) and/or (4) Section 13.2(d)(ii) (in each case to the limited extent
expressly set forth in such Sections). Notwithstanding anything in this
Agreement to the contrary, in no event shall there by any Environmental Defect,
and Buyer shall not be permitted to deliver an Environmental Defect Notice, with
respect to (i) any Subject Property operated by Buyer or its Affiliates, or (ii)
any Subject Property in which Seller owns only an overriding royalty interest,
and all Liabilities with respect to the foregoing (including to the extent
relating to the Conveyed Interests) shall be deemed to constitute Assumed
Obligations.
(d)    Exclusive Remedy. Except for Buyer’s rights (i) to terminate this
Agreement pursuant to Section 14.1(e) and (ii) to indemnification pursuant to
(A) Section 13.2(a) (with respect to a breach by Seller of Section 7.15), (B)
Section 13.2(b) (with respect to a breach by Seller of Section 9.1), (C) Section
13.2(d)(i), and/or (D) Section 13.2(d)(ii) (in each case to the limited extent
expressly set forth in such Sections), the provisions set forth in
Section 6.1(c) shall be the exclusive right and remedy of Buyer with respect to
any Environmental Defect, Environmental Condition, or other environmental matter
with respect to any Conveyed Interest.
(e)    Environmental Threshold and Deductible. Notwithstanding anything herein
to the contrary, except as otherwise provided in the last sentence of this
Section 6.1(e), with respect to any Environmental Defect timely and properly
asserted under Section 6.1(a), (i) in no event shall there be any adjustment to
the Purchase Price or other remedies provided by Seller for any Environmental
Defect with respect to an individual Environmental Defect Property (or
Environmental Defects, if more than one Environmental Defect affects the
individual Environmental Defect Property) for which the Remediation Amount (or
aggregate Remediation Amounts, if applicable) does not exceed $70,000 (the
“Individual Environmental Threshold”); and (ii) in no event shall there be any
adjustment to the Purchase Price or other remedies provided by Seller for any
Environmental Defect (or Environmental Defects, if applicable) affecting an
individual Environmental Defect Property for which the Remediation Amount (or
aggregate Remediation

30

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

Amounts, if applicable) exceeds the Individual Environmental Threshold unless
(A) the amount of the sum of (1) the aggregate Remediation Amounts of all such
Environmental Defects that exceed the Individual Environmental Threshold (as
determined in accordance with (i) above, but excluding any Remediation Amounts
attributable to any Environmental Defects cured by Seller and Conveyed Interests
retained by Seller pursuant to Section (c)) plus (2) (x) the aggregate Title
Defect Amounts of all Title Defects that exceed the Individual Title Defect
Threshold (as determined in accordance with Section 5.3(i), but excluding any
Title Defect Amounts attributable to Title Defects cured by Seller) less (y) the
aggregate Title Benefit Amount of all Title Benefits, exceeds (B) the Aggregate
Deductible, after which point Buyer shall be entitled to adjustments to the
Purchase Price or other applicable remedies available hereunder, but only with
respect to the amount by which the aggregate amount of such Remediation Amounts
and Title Defect Amounts exceeds the Aggregate Deductible. For the avoidance of
doubt, in the instance an identical Environmental Defect is present with respect
to multiple Subject Properties, the Remediation Amounts for all such identical
Environmental Defects shall not be aggregated when determining whether the
Individual Environmental Threshold has been satisfied. Notwithstanding the
foregoing, the Individual Title Defect Threshold and the Aggregate Deductible
shall not apply to any Title Defect timely and properly asserted under Section
5.3(a) with respect to any of the Leases set forth on Schedule 5.3(i).
(f)    Environmental Dispute Resolution. Seller and Buyer shall attempt to agree
on (i) all Environmental Defects and Remediation Amounts prior to the Dispute
Date and (ii) the adequacy of any cure by Seller of any asserted Environmental
Defect prior to the Dispute Date (items (i) and (ii), collectively, the
“Disputed Environmental Matters”). If Seller and Buyer are unable to agree by
the Dispute Date, the Disputed Environmental Matters shall be exclusively and
finally resolved by arbitration pursuant to this Section 6.1(f). There shall be
a single arbitrator, who shall be an environmental attorney with at least
10 years’ experience in environmental matters involving oil and gas producing
properties in any of the regional areas in which the affected Conveyed Interests
are located, as selected by the mutual agreement of Buyer and Seller within
15 days after the Dispute Date (the “Environmental Arbitrator”). If the Parties
do not mutually agree upon the Environmental Arbitrator in accordance with this
Section 6.1(f), the Dallas, Texas office of the AAA shall appoint such
Environmental Arbitrator under such conditions as the AAA in its sole discretion
deems necessary or advisable. The place of arbitration shall be Dallas, 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(f). Each of
Buyer and Seller shall submit to the Environmental Arbitrator, with a
simultaneous copy to the other Party, a single written statement of its position
on the Disputed Environmental Matters in question, together with a copy of this
Agreement and any supporting material that such Party desires to furnish, not
later than the 10th Business Day after appointment of the Environmental
Arbitrator. The Environmental Arbitrator’s determination shall be made within
20 days after the end of such 10 Business Day period after the submission of the
Disputed Environmental Matters and shall be final and binding upon both Parties,
without right of appeal. In making his determination, the Environmental
Arbitrator shall make a determination of the Disputed Environmental Matters
submitted based solely on the single written submission of Seller and Buyer (and
without any additional or supplemental submittals by any Party, except to the
extent the Environmental Arbitrator requests additional information from either
Party), shall be bound by the rules set forth in this Section 6.1 and, subject
to the foregoing, may consider such other legal and industry matters as in the
opinion of the Environmental Arbitrator are

31

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

necessary or helpful to make a proper determination. The Environmental
Arbitrator, however, may not award Buyer a greater Remediation Amount than the
Remediation Amount claimed by Buyer in its applicable Environmental Defect
Notice or a lesser Remediation Amount than the Remediation Amount claimed by
Seller in its applicable position statement delivered to the Environmental
Arbitrator. The Environmental Arbitrator shall act as an expert for the limited
purpose of determining specific Disputed Environmental Matters submitted by
either Party and may not award damages, interest or penalties to either Party
with respect to any matter, except as otherwise provided in the following
sentence. The costs of the Environmental Arbitrator (and the AAA, if applicable)
and the reasonable legal costs and expenses incurred by the Parties in
connection with the arbitration shall be borne pro rata between the Parties with
each Party being responsible for such costs and expenses to the extent the
Environmental Arbitrator has not selected such Party’s position on an aggregate
dollar basis with respect to all amounts submitted for resolution by the
Environmental Arbitrator.
6.2    NORM, Asbestos, Wastes and Other Substances. Buyer acknowledges that the
Conveyed Interests 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 Conveyed Interests or
associated with the Conveyed Interests. Equipment and sites included in the
Conveyed Interests may contain asbestos, NORM or other Hazardous Substances.
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
Conveyed Interests or included in the Conveyed Interests may contain asbestos,
NORM and other wastes or Hazardous Substances. NORM containing material and/or
other wastes or Hazardous Substances 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 any affected environmental media, wastes, asbestos, NORM and other
Hazardous Substances from the Conveyed Interests. Notwithstanding anything
herein to the contrary, Buyer shall not be permitted to claim any Environmental
Defect on the account of the presence of NORM or asbestos-containing materials
that are non-friable, unless and only to the extent such presence of NORM or
asbestos-containing materials that are non-friable constitutes an Environmental
Condition.
ARTICLE VII

Agreement and the Transaction Documents to which it is a party and the
consummation of the transactions contemplated herein and therein will not (a)
conflict with or result in a breach of any provisions of the organizational

material default or the creation of any Encumbrance or give rise to any right of

hereunder; and there has been no settlement of litigation with Third Parties or
order of any Governmental Authority with respect to the ownership or operation

extent reflected in the Net Revenue Interest and Working Interest for such
Conveyed Interest set forth in Exhibit A or Exhibit B, as applicable. Seller has

Guarantee or such Governmental Bond (and all costs incurred in connection with

indemnity claim made under Section 13.2 for review and copying at Seller’s
expense, provided that (i) Buyer will not be required to disclose any materials
subject to the attorney-client privilege, the attorney work-product doctrine,
confidentiality restrictions, or any other applicable immunity from disclosure,
(ii) Buyer’s provision to Seller, its Affiliates and their respective
representatives of access to materials under this Section 9.4 shall not
constitute an admission that any such materials are relevant to any given
indemnity claim, (iii) (A) Buyer’s inadvertent provision to Seller, its
Affiliates and their respective representatives of access to confidential
materials and/or materials subject to the attorney-client privilege or attorney
work-product doctrine shall not constitute a waiver of the applicable privilege
or protection and (B) upon discovery of the inadvertent disclosure, Buyer shall
retain the right to assert all applicable privileges and protections and Seller,
its Affiliates and their respective representatives shall be prohibited from
using the inadvertently disclosed documents for any purpose, and (iv) all
Records and materials provided under this Section 9.4 shall be treated by
Seller, its Affiliates and their respective representatives as confidential and
shall not be disclosed or provided to any Third-Party without the express

provide Seller a reasonable opportunity to copy any or all of such Records at
Seller’s expense.
9.5    Knowledge of Breach. Buyer will notify Seller, and Seller will notify
Buyer, promptly and in reasonable detail promptly after such Party or any
Affiliate of such Party, obtains Knowledge that any representation, warranty,
covenant, or other agreement of the other Party contained in this Agreement is,
becomes, or will be untrue, or has been or may be breached, as applicable, in
any material respect on or before the Closing Date. Notwithstanding the

be deemed a material breach of this Agreement by such Party or constitute a
failure of any condition in Article X or Article XI and (b) this Section 9.5
shall not be deemed or constitute a waiver by a Party of (or give rise to any
defense on the part of the other Party to) any rights or remedies of such Party
contained in this Agreement in respect of any breach hereof by the other Party.

condition of this Agreement shall be deemed to be a breach of this Agreement for
any purpose under this Agreement if the other Party had Knowledge of such breach
prior to the Execution Date.

hereafter occurring which, if existing on the Execution Date or thereafter,
would have been required to be set forth or described in such Schedules. For all
purposes of this Agreement, including for purposes of determining whether the
conditions set forth in Article X have been fulfilled and whether Seller has

independent contractor, consultant, or other Third Party) or employ (including
as a consultant) any officer, employee, or field personnel of or under contract
to the other Party or any Affiliate of the other Party without obtaining the
prior written consent of Seller, if the first Party came into contact with such
officer, employee or field personnel in connection with the transactions
contemplated by this Agreement (any such officers, employees or field personnel,

or its Affiliates from (A) hiring a Subject Employee who responds to a general

Closing Date (the “Suspense Transfer Date”)) assume and fulfill, perform, pay
and discharge (or cause to be fulfilled, performed, paid and discharged) all
obligations and Liabilities arising from, based upon, related to or associated
with the payment of all proceeds from sales of Hydrocarbons relating to the
Conveyed Interests and payable to owners of working interests, royalties,
overriding royalties and other similar interests or Burdens (in each case) that
are held by Seller in suspense. Such payments held in suspense (a) will not be
included in the calculation of the adjustments to the Purchase Price for the
Preliminary Settlement Statement and (b) shall be included in the calculation of
the adjustments to the Purchase Price for the Final Settlement Statement in
accordance with Section 3.3(b)(ix). From the Suspense Transfer Date until the
first anniversary thereof, Seller may transfer additional suspense obligation
discovered and/or identified following the Suspense Transfer Date, together with
any suspense funds related thereto, to Buyer up to two times, and Seller shall
have no further right or obligation to transfer suspense obligations and/or
funds unless otherwise agreed by the Parties.
9.9    Tag-Along Rights. Buyer acknowledges that certain of the Conveyed
Interests are subject to the rights of the Third Parties identified in Schedule
9.9 (the “Tag Parties”) to include certain of their respective interests in the
Subject Properties (such interests, as set forth on Schedule 9.9, the “Tag
Interests”) as part of the transactions contemplated hereunder (the “Tag
Rights”). Accordingly, no later than 10 days after the Execution Date, Seller
shall send to each Tag Party a notice of, and opportunity to participate as a
seller in the transactions contemplated by this Agreement in accordance with the
contractual provisions governing the Tag Rights and for the applicable allocated
values set forth on Schedule 9.9 for the respective Tag Interests. If a Tag
Party notifies Seller in writing prior to Closing, and, in any event, before the
expiration of its Tag Rights, that it is exercising its Tag Right with respect
to its Tag Interests, this Agreement shall be amended to include that Tag Party
as a seller hereto (each, a “Tag Seller Party,” and, together with Seller, the
“Seller Parties”) with respect to those Tag Interests prior to Closing (which
Tag Interests shall, upon such execution and delivery of such amendment, become
part of the “Conveyed Interests”), on the following terms and conditions:

46

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

(a)    By its execution of this Agreement and for a period beginning on the date
of such execution and ending 180 days after Closing, each Tag Seller Party
irrevocably authorizes Seller to act on that Tag Seller Party’s behalf until 180
days after the Closing with respect to the following matters pertaining to this
Agreement: (i) delivering and receiving all notices, statements, reports, and
other information given by or addressed to one or more of the Seller Parties
hereunder, (ii) making, on a joint basis, all elections that any Seller Party is
entitled to make hereunder, and (iii) negotiating, compromising, and resolving
any matters related to this Agreement, including Title Defects, Environmental
Defects, Casualty Losses, Preferential Purchase Rights, Consents, the
Preliminary Settlement Statement, and the Final Settlement Statement, and Seller
hereby agrees to perform those matters, subject to the provisions of this
Section 9.9 (collectively, the “Representative Services”); provided, however,
that notwithstanding the foregoing, the Representative Services shall not
include, and Seller shall not serve as a Tag Seller Party’s representative, or
have any obligation to the Tag Seller Parties, with respect to (A) receiving or
disbursing any amounts due to a Tag Seller Party under this Agreement, (B) any
claims asserted by Buyer against a Tag Seller Party under Section 13.2, (C) any
claims asserted by a Tag Seller Party against Buyer under Section 13.3, (D) any
other indemnity matters, (E) the negotiation, compromise, or resolution of any
matters related to any Claim Notices or other indemnity matters, or (F) any
administrative functions or other actions (such as giving and receiving notices)
related to any Claim Notices or other indemnity matters.
(b)    Seller shall have no Liability to the Tag Seller Parties for, and each
Tag Seller Party HEREBY RELEASES Seller from and against, all Liabilities
relating to, arising out of, or resulting in any way from Seller’s performance
and discharge, or failure to perform and discharge, the Representative Services,
including any action or decision taken or made by Seller under, pursuant to, or
in connection with this Agreement, the transactions contemplated hereby, or any
related agreements in its role as the Tag Seller Parties’ representative,
HOWSOEVER ARISING AND WHETHER OR NOT SUCH CLAIMS ARISE OUT OF THE NEGLIGENCE
(WHETHER SOLE, JOINT OR CONCURRENT OR ACTIVE OR PASSIVE), STRICT LIABILITY, OR
OTHER FAULT OR BREACH OF LEGAL DUTY OF ANY OF THE SELLER INDEMNIFIED PARTIES,
except for any such Liabilities that may result from (and only to the extent it
results from) Seller’s gross negligence or willful misconduct. EACH TAG SELLER
PARTY ACKNOWLEDGES AND AGREES THAT SELLER IS NOT ACTING IN ANY FIDUCIARY
CAPACITY WHATSOEVER FOR OR ON BEHALF OF THAT TAG SELLER PARTY WITH RESPECT TO
THIS AGREEMENT OR OTHERWISE, AND THAT SELLER’S AGREEMENT TO PERFORM THE MATTERS
PROVIDED FOR IN THIS SECTION 9.9 FOR THE TAG SELLER PARTIES IS MADE AS AN
ACCOMMODATION ONLY.
(c)    Each Tag Seller Party, by the execution of this Agreement, expressly
acknowledges and agrees that Buyer shall be entitled to rely on any and all
actions and decisions taken or made by Seller under or pursuant to this
Agreement that are within the scope of Seller’s authority under Section 9.9(a)
without any liability to, or obligation to inquire of, such Tag Seller Party.
Any notice or communication given or received by, and any decision, action,
failure to act within a designated period of time by, or instruction of, Seller
that is within the scope of Seller’s authority under Section 9.9(a) shall
constitute a notice or communication to or by all Seller Parties and shall be
final, binding, and conclusive upon each Tag Seller Party. SELLER WILL INDEMNIFY
AND HOLD HARMLESS, AND EACH TAG SELLER PARTY RELEASES, EACH BUYER

47

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

INDEMNIFIED PARTY FROM AND AGAINST ANY AND ALL LIABILITIES IN FAVOR OF ANY
SELLER INDEMNIFIED PARTY ARISING OUT OF, OR RESULTING IN ANY WAY FROM, THE
PERFORMANCE AND DISCHARGE, OR THE FAILURE TO PERFORM OR DISCHARGE, BY SELLER OF
THE REPRESENTATIVE SERVICES.
(d)    If any Seller Party has not satisfied the conditions to Closing set forth
in Article X (as such conditions relate to such Seller Party), Buyer will have
the right, if so desired, to not close the transactions contemplated hereunder
as to such Seller Party and to close the transactions contemplated hereunder as
to the other Seller Parties; provided, that, (i) notwithstanding the foregoing,
if the conditions to Closing set forth in Article X are satisfied as they relate
to Seller, but have not been satisfied as to a Tag Seller Party, Buyer will
still be required to close the transactions contemplated hereunder (subject to
the other terms and conditions hereof) as to the Conveyed Interests of Seller
and (ii) if the conditions to Closing set forth in Article X are not satisfied
as they relate to Seller, but have been satisfied as to any or all of the Tag
Seller Parties, Buyer will not be required to close any of the transactions
contemplated hereunder (subject to the other terms and conditions hereof).
(e)    All thresholds, deductibles, caps, and similar limitations herein shall
be reduced, and apply separately, for each Tag Seller Party, on a pro rata basis
determined by dividing the relevant Tag Interest by the relevant Conveyed
Interests. Further, the benefit or burden of any adjustment to the Purchase
Price, to the extent applicable to two or more of the Seller Parties, shall be
allocated among those Seller Parties on the same pro rata basis referenced in
the preceding sentence.
(f)    Notwithstanding anything in this Agreement to the contrary, the
Liabilities of the Seller Parties under this Agreement shall be shared
severally, and not jointly, by each Seller Party.
The Parties’ failure to agree on the above-mentioned amendment will not
constitute a failure of any condition in Article X and Article XI.
9.10    Transition Services Agreement. Between the Execution Date and the
Closing Date, the Parties will use commercially reasonably efforts to negotiate
a form of transition services agreement (the “Transition Services Agreement”) to
be executed at Closing by the Parties, establishing the terms under which Seller
would provide certain transition services (at a minimum, operations, accounting,
information technology and marketing services) in respect of the Conveyed
Interests for a limited period of time following the Closing. If the Parties do
not reach an agreement regarding such a Transition Services Agreement, the
Closing shall nonetheless occur (subject to the other terms of this Agreement)
and, thereafter, for a period of 60 days following the Closing, Seller shall
provide transition services pursuant to (and subject to the limitations set
forth in) the term sheet set forth on Exhibit L in substantially the same manner
as Seller or its Affiliates performed such services during the one-year period
immediately prior to the Execution Date and Buyer agrees to be bound by the
release and indemnification terms set forth therein with respect to such
transition services.

48

49

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

9.11    Audits and Filings.
(a)    Seller acknowledges that Buyer and its Affiliates may be required to
include statements of revenues and direct operating expenses and other financial
information relating to the Conveyed Interests for one or more years or interim
periods ending on or prior to the Closing (collectively, the “Financial
Statements”), and that such Financial Statements may be required to be audited
or reviewed in accordance with GAAP and may need to comply with the requirements
of the SEC for inclusion or incorporation by reference into one or more
registration statements, reports or other documents (collectively, “SEC
Documents”) required to be filed by Buyer or its Affiliates under the Securities
Act of 1933, as amended (the “Securities Act”), the Securities Exchange Act of
1934, as amended (the “Exchange Act”), and the rules set forth in Regulation
S-X, or other rules promulgated thereunder or in an offering memorandum relating
to a private placement of securities exempt from registration under the
Securities Act (“Offering Document”). From and after the Execution Date, Seller
shall, shall cause its Affiliates to, and shall use commercially reasonable
efforts to cause its accountants and counsel to, cooperate with Buyer, its
Affiliates and their respective agents, advisors and representatives in
preparing and obtaining the Financial Statements to the extent that Seller or
such other persons has such information available or can obtain such information
using commercially reasonable efforts. Further, from and after the Execution
Date and following reasonable advance notice from Buyer to Seller, Seller shall,
shall cause its Affiliates to, and shall use commercially reasonable efforts to
cause its accountants and counsel to, make available during normal business
hours to Buyer and its Affiliates and their agents, advisors and representatives
reasonable access to any and all books, records, information and documents that
are attributable to the Conveyed Interests in any of Seller’s or any of its
Affiliates’ possession or control if reasonably required by Buyer or its
Affiliates in connection with the creation and audit or review of the Financial
Statements. Buyer shall be responsible for, and obligated to promptly reimburse
Seller for (in any event, not less than within ten (10) Business Days after
receipt of demand in writing therefor), any and all reasonable costs and
expenses (including third person or internal resources and personnel) incurred
by Seller or its Affiliates to the extent associated with preparing and
obtaining the Financial Statements solely pursuant to this Section 9.11 and
otherwise complying with the provisions of this Section 9.11.
(b)    To the extent requested by Buyer, Seller shall use its commercially
reasonable efforts to obtain representation letters and similar documents (in
each case, in form and substance customary for representation letters provided
to external audit firms by management of a company whose financial statements
are the subject of an audit or review used in filings of acquired company
financial statements under the Exchange Act) from applicable personnel of Seller
and its Affiliates as may be required in connection with the preparation and
audit or review of the Financial Statements or delivery of a “comfort letter”
for a securities offering by Buyer or its Affiliates and solely to the extent
related to the Conveyed Interests. To the extent requested by Buyer, Seller
shall use its commercially reasonable efforts to provide and request that each
independent audit firm that audits or reviews the Financial Statements provide
consents necessary for the inclusion or incorporation by reference of the
Financial Statements in any SEC Document or any Offering Document in which the
Financial Statements are required to be included or incorporated.

50

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

(c)    Subject and without prejudice to Buyer’s rights hereunder with respect to
Seller’s representation and warranties in Article VII (to the limited extent
expressly set forth therein), all of the information provided by Seller or its
Affiliates pursuant to this Section 9.11 is given without any representation or
warranty, express or implied, and no Seller Indemnified Party shall have any
liability or responsibility with respect thereto. Without prejudice to Buyer’s
rights and remedies under Article XIII and, if applicable, Section 14.1(d) (and
except for and excluding any of the following to the extent arising from the
gross negligence or willful misconduct of any Seller Indemnified Party), Buyer,
for itself and for each member of the Buyer Indemnified Parties, hereby
releases, defends, indemnifies, remises and forever discharges each member of
the Seller Indemnified Parties from any and all suits, legal or administrative
proceedings, claims, demands, damages, losses, costs, Liabilities, interest or
causes of action whatsoever, at law or in equity, known or unknown, suffered or
incurred by any Seller Indemnified Party based on, relating to or arising out of
the information provided by Seller or its Affiliates pursuant to this Section
9.11.
(d)    For a period of three years following the Closing Date, Seller shall, and
shall cause its respective Affiliates to, retain all books, records, information
and documents in their or their Affiliates’ possession that are necessary to
prepare and audit the Financial Statements, except to the extent originals or
copies thereof are transferred to Buyer in connection with Closing.
9.12    Buyer Financing.
(a)    None of the Financing Sources will have any liability to any Seller
Indemnified Party relating to or arising out of this Agreement, the Financing or
otherwise in connection with the transactions contemplated by this Agreement,
whether at law or in equity, in contract, in tort, or otherwise, and none of the
Seller Indemnified Parties will have any rights or claims (and will not bring or
support any claims) against any of the Financing Sources hereunder or thereunder
in connection with the transactions contemplated, whether at law or in equity,
in contract, in tort, or otherwise.  Each Party agrees that (i) it will not, and
will not permit its controlled Affiliates to, bring or support any action,
claim, cause of action or similar claims or assertions of any kind or
description, whether at law or in equity, whether in contract or in tort or
otherwise, against the Financing Sources in any way relating to this Agreement
or any of the transactions contemplated by this Agreement, including with
respect to any dispute arising out of or relating in any way to the Financing or
the performance thereof, in any forum other the United States District Court for
the Southern District of New York or any court of the State of New York sitting
in the Borough of Manhattan in the City of New York and (ii) any such action,
claim, cause of action or similar claims or assertions will be instituted
exclusively in the courts of the United States District Court for the Southern
District of New York or any court of the State of New York sitting in the
Borough of Manhattan in the City of New York and each Party hereby irrevocably
consents to the exclusive jurisdiction and venue in connection with any such
action, claim, cause of action or similar claims or assertions. EACH OF THE
PARTIES HEREBY VOLUNTARILY AND IRREVOCABLY WAIVES TRIAL BY JURY IN ANY
LITIGATION, ACTION OR OTHER PROCEEDING BROUGHT IN CONNECTION WITH ANY ACTION,
CLAIM, CAUSE OF ACTION OR SIMILAR CLAIMS OR ASSERTIONS OF ANY KIND OR
DESCRIPTION REFERRED TO IN THIS SECTION 9.12(a). EACH OF THE PARTIES AGREES
THAT, SECTION 15.14 NOTWITHSTANDING, THIS SECTION 9.12(A) SHALL BE INTERPRETED,

use their respective commercially reasonable efforts to provide or cause to be
provided, to Buyer, in each case, at Buyer’s sole expense, all cooperation
reasonably requested by Buyer that is necessary or customary in connection with
any Financing contemplated by Buyer for purposes of the transactions
contemplated by this Agreement. None of Seller or its Affiliates shall be
required to take any action pursuant to this Section 9.12(b) that would subject
it to any Liability or to bear any cost or expense or to pay any commitment or
other fee. BUYER SHALL INDEMNIFY AND HOLD HARMLESS THE SELLER INDEMNIFIED
PARTIES FROM AND AGAINST ANY AND ALL LIABILITIES SUFFERED OR INCURRED BY THEM IN
CONNECTION WITH THE ARRANGEMENT OF SUCH FINANCING (INCLUDING ANY ACTION TAKEN AT
BUYER’S REQUEST PURSUANT TO THIS SECTION 9.12(b)) AND ANY INFORMATION UTILIZED
IN CONNECTION THEREWITH, EXCEPT TO THE EXTENT CAUSED BY THE GROSS NEGLIGENCE OR
WILLFUL MISCONDUCT OF THE SELLER INDEMNIFIED PARTIES. Buyer shall be responsible
for, and shall promptly reimburse Seller upon written request by Seller for, any
and all reasonable costs and expenses incurred by Seller or its Affiliates in
connection with the Financing or the cooperation provided at Buyer’s request
pursuant to this Section 9.12(b).

SUBJECT PROPERTIES OPERATED BY THE OTHER PARTY, OR AS ANY OPERATOR OF ANY
SUBJECT PROPERTIES IN WHICH THE OTHER PARTY IS A NON-OPERATOR, SHALL NOT BE
PREJUDICED OR OTHERWISE AFFECTED BY THE PROVISIONS OF THIS AGREEMENT (OTHER THAN
(a) TITLE DEFECTS OR OTHER

60

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

TITLE MATTERS, WHICH FOLLOWING CLOSING SHALL BE EXCLUSIVELY ADDRESSED AS SET
FORTH IN SECTION 5.1 AND (b) ENVIRONMENTAL DEFECTS, ENVIRONMENTAL CONDITIONS, OR
OTHER ENVIRONMENTAL MATTERS, WHICH FOLLOWING CLOSING SHALL BE EXCLUSIVELY
ADDRESSED HEREIN IN ARTICLE VI, AND, AS APPLICABLE, SECTIONS 13.2(a) (WITH
RESPECT TO A BREACH OF SECTION 7.15), 13.2(b) (WITH RESPECT TO A BREACH OF
SECTION 9.1), 13.2(d) AND 13.3).
13.7    Indemnification Procedures. All claims for indemnification hereunder,
including Sections 4.1(c), 5.3(c), 9.3, 9.9, 9.10 (if a Transition Services
Agreement is not executed at Closing), 13.2 and 13.3 (for purposes of this
Section 13.7, the “indemnification provisions”) shall be asserted and resolved
as follows:
(a)    For purposes of the indemnification provisions, the term “Indemnifying
Party” when used in connection with particular Liabilities shall mean the Party
or Parties having an obligation to indemnify another Party and/or other
Person(s) with respect to such Liabilities pursuant to the indemnification
provisions, and the term “Indemnified Party” when used in connection with
particular Liabilities shall mean the Party and/or other Person(s) having the
right to be indemnified with respect to such Liabilities by the Indemnifying
Party pursuant to the indemnification provisions.
(b)    To make a claim for indemnification under the indemnification provisions,
an Indemnified Party shall notify the Indemnifying Party in writing of its claim
under this Section 13.7, including the specific details of and specific basis
under this Agreement for its claim as then known by the Indemnified Party (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 provide its Claim Notice promptly after the
Indemnified Party has actual 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 13.7(b) shall not relieve the
Indemnifying Party of its obligations under the indemnification provisions (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 or agreement, the Claim Notice shall specify the
representation, warranty, covenant 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
obligation to defend and indemnify 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.

61

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

(d)    If the Indemnifying Party admits its obligation to defend and indemnify
the Indemnified Party against a Third Party Claim, it shall have the right and
obligation to diligently defend and indemnify, at its sole cost and expense, the
Indemnified Party against 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 agrees to cooperate in contesting any Third Party Claim which the
Indemnifying Party elects to contest. The Indemnified Party may participate in,
but not control, with its own counsel and at its own expense, any defense or
settlement of any Third Party Claim controlled by the Indemnifying Party
pursuant to this Section 13.7(d). An Indemnifying Party shall not, without the
written consent of the Indemnified Party, (i) settle any Third Party Claim or
consent to the entry of any judgment with respect thereto which does not include
a full and unconditional written release of the Indemnified Party from all
Liability in respect of such Third Party Claim without any admission or finding
of fault or liability on the part of the Indemnified Party or (ii) settle any
Third Party Claim or consent to the entry of any judgment with respect thereto
in any manner that may materially and adversely affect the Indemnified Party
(other than as a result of money damages fully paid by the Indemnifying Party).
(e)    If the Indemnifying Party does not admit its obligation or admits its
obligation to defend and indemnify the Indemnified Party against a Third Party
Claim, but fails to diligently prosecute, indemnify against 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 the Indemnified Party’s choosing. The Indemnifying Party may
participate in, but not control, with its own counsel and at its own expense,
any defense or settlement of any Third Party Claim controlled by the Indemnified
Party pursuant to this Section 13.7(e). If the Indemnifying Party has not yet
admitted its obligation to defend and indemnify the Indemnified Party against a
Third Party Claim, the Indemnified Party shall send written notice to the
Indemnifying Party of any proposed settlement and the Indemnifying Party shall
have the option for 10 days following receipt of such notice to %3) admit in
writing its obligation to indemnify the Indemnified Party from and against the
liability and consent to such settlement, %3) if liability is so admitted,
reject, in its reasonable judgment, the proposed settlement, or %3) deny
liability. Any failure by the Indemnifying Party to respond to such notice shall
be deemed to be an election under subsection (iii) 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 dispute the claim for
such Liabilities.
(g)    The indemnification provisions in this Section 13.7 will apply mutatis
mutandis to any indemnity obligations hereunder of the Parties that are not
referenced in Section 13.7(a).

Agreement shall survive Closing without time limit. Representations, warranties,
covenants and agreements shall be of no further force or effect after the date
of their expiration, 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 or agreement prior to its expiration date.
(b)    The indemnities in Sections 13.2(a), 13.2(b), 13.3(a) and 13.3(b) shall
terminate as of the expiration date of each respective representation, warranty,
covenant or agreement that is subject to indemnification. Seller’s indemnities
set forth in Section 13.2(c) (i) with respect to Operating Expenses that
constitute Specified Obligations under subsection (vi) of the Specified
Obligations, shall terminate 24 calendar months after Closing and (ii) with
respect to all other Specified Obligations, shall terminate on the earlier of
the (A) the expiration of the applicable statute of limitations and (B) 48
calendar months after Closing. Seller’s indemnity set forth in Section

time limit. Notwithstanding the foregoing, there shall be no termination of any
bona fide claim asserted pursuant to the indemnities in Sections 13.2(a) through
13.2(c), Section 13.2(d)(ii) or Sections 13.3(a) through 13.3(b) prior to the
date of termination for such indemnity.
13.9    Non‑Compensatory Damages. None of the Buyer Indemnified Parties nor
Seller Indemnified Parties shall be entitled to recover from Seller or Buyer, or
their respective Affiliates, any special, indirect, consequential, punitive,
exemplary, remote or speculative damages or damages for lost profits of any kind
arising under or in connection with this Agreement or the transactions
contemplated hereby, except to the extent any such Party suffers such damages to
a Third Party, which damages (including costs of defense and reasonable
attorneys’ fees incurred in connection with defending against such damages)
shall not be excluded by this provision as to recovery hereunder. Subject to the
preceding sentence, Buyer, on behalf of each of the Buyer Indemnified Parties,
and Seller, on behalf of each of the Seller Indemnified Parties, waive any right
to recover special, indirect, consequential, punitive, exemplary, remote or
speculative, or damages for lost profits of any kind, arising in connection with
or with respect to this Agreement or the transactions contemplated hereby.
13.10    Waiver of Right to Rescission. Seller and Buyer acknowledge that,
following Closing, the payment of money or specific performance (with respect
the performance of covenants

63

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

or agreements herein following Closing), in each case, as may be limited by the
terms of this Agreement, shall be adequate compensation for breach of any
representation, warranty, covenant or agreement contained herein or for any
other claim arising in connection with or with respect to the transactions
contemplated by this Agreement. As the payment of money or specific performance
(with respect the performance of covenants or agreements herein following
Closing) shall be adequate compensation, following Closing, Buyer and Seller
waive any right to rescind this Agreement or any of the transactions
contemplated hereby.

Indemnified Parties or the Buyer Indemnified Parties, as the case may be, is
entitled to indemnification under this Agreement or in connection with or with
respect to the transactions contemplated by this Agreement (for purposes of this
Section 13.11, the “indemnified party”) shall be reduced by any corresponding
insurance proceeds from insurance policies carried by the indemnified party that
are realized by the indemnified party.
13.12    Disclaimer of Application of Anti-Indemnity Statutes. THE PARTIES
ACKNOWLEDGE AND AGREE THAT THE PROVISIONS OF ANY ANTI-INDEMNITY STATUTE RELATING
TO OILFIELD SERVICES AND ASSOCIATED ACTIVITIES SHALL NOT BE APPLICABLE TO THIS
AGREEMENT AND/OR THE TRANSACTIONS CONTEMPLATED HEREBY.

ARTICLE XIV
TERMINATION, DEFAULT AND REMEDIES
14.1    Right of Termination. This Agreement and the transactions contemplated
herein may be terminated at any time prior to Closing by delivery of written
notice to the other Party:
(a)    by the mutual prior written consent of Seller and Buyer;
(b)    by either Seller or Buyer if Closing has not occurred on or before
December 31, 2017 (or such later date as agreed to in writing by Seller and
Buyer);
(c)    by Seller, at Seller’s option, if any of the conditions set forth in
Article XI have not been (or cannot be) satisfied on or before the Scheduled
Closing Date and, following written notice thereof from Seller to Buyer
specifying the reason such condition is (or will be) unsatisfied (including any
breach by Buyer of this Agreement), such condition remains unsatisfied for a
period of 10 Business Days after Buyer’s receipt of written notice thereof from
Seller;
(d)    by Buyer, at Buyer’s option, if any of the conditions set forth in
Article X have not been (or cannot be) satisfied on or before the Scheduled
Closing Date and, following written notice thereof from Buyer to Seller
specifying the reason such condition is (or will be) unsatisfied (including any
breach by Seller of this Agreement), such condition remains unsatisfied for a
period of 10 Business Days after Seller’s receipt of written notice thereof from
Buyer;

64

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

(e)    by Buyer if the condition set forth in Section 10.4 is not satisfied on
or before the Scheduled Closing Date or by Seller if the condition set forth in
Section 11.4 is not satisfied on the Scheduled Closing Date; or
(f)    by Seller if Buyer fails to pay the Deposit in accordance with Section
3.2;
provided, however, that (i) neither Party shall be entitled to terminate this
Agreement pursuant to Sections 14.1(b) through 14.1(e) above if such Party or
its Affiliates are, at such time, in material breach of any provision of this
Agreement and, (ii) notwithstanding anything to the contrary, the Parties’
failure to agree on the amendment referenced in Section 9.9 and/or the
Transition Services Agreement during the Interim Period pursuant to Section 9.10
will not be deemed a material breach of this Agreement or constitute a failure
of any condition in Article X or Article XI. For the avoidance of doubt, any
breach of Section 8.8 shall be deemed a material breach of this Agreement by
Buyer.
14.2    Effect of Termination.
(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 Article I, Sections 4.1(c) through 4.1(g), 4.2,
4.3, 5.3(c) (as to the indemnity therein), 6.1(b) (as to the indemnity therein),
9.7, 9.9(b), 9.9(c), 9.11(c), 9.12(a), 13.9, this Section 14.2, Section 14.3,
Article XV (other than Sections 15.2(b) through (e), 15.7, 15.8, 15.16, and
15.18) and such of the defined terms in Appendix I 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 has the right to terminate this Agreement pursuant to
Section 14.1(c) because a condition set forth in Sections 11.1, 11.2 or 11.5 has
not been satisfied, (A) all of the conditions in Article X (excluding conditions
that, by their terms, cannot be satisfied until the Closing) have been satisfied
(or waived by Buyer) (unless the failure to satisfy such condition arises from
the action or inaction by Buyer or any Buyer Indemnified Party), and (B) Seller
is ready, willing and able to perform its obligations under Section 12.3, then,
in such event, Seller shall have the right to, at its option, (1) as Seller’s
sole and exclusive remedy, terminate this Agreement pursuant to Section 14.1(c)
and receive the Deposit from the Escrow Agent as liquidated damages, and not as
a penalty, for such termination, free and clear of any claims thereon by Buyer,
or (2) in lieu of terminating this Agreement, seek all remedies available at law
or in equity, including specific performance by Buyer. The provision for payment
of the Deposit as liquidated damages in this Section 14.2 has been included
because, in the event of a termination of this Agreement permitting Seller to
receive the Deposit, the actual damages to be incurred by Seller can reasonably
be expected to approximate the amount of liquidated damages called for herein
and because the actual amount of such damages would be difficult if not
impossible to measure accurately.
(c)    If Buyer has the right to terminate this Agreement pursuant to
Section 14.1(d) because a condition set forth in Sections 10.1, 10.2 or 10.5 has
not been satisfied, (A) all of the conditions in Article XI (excluding
conditions that, by their terms, cannot be satisfied until the Closing) have
been satisfied (or waived by Seller) (unless the failure to satisfy such
condition arises from the action or inaction by Seller or any Seller Indemnified
Party), and (B) Buyer is ready, willing and able to perform its obligations
under Section 12.3, then, in such event, Buyer shall have the

65

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

right to, at its option, (1) terminate this Agreement, receive the Deposit from
the Escrow Agent, and seek actual damages (incurred by Buyer) against Seller as
a result of Seller’s breach of its covenants, agreements, representations or
warranties (as the case may be) hereunder or (2) in lieu of terminating this
Agreement, seek all remedies available at law or in equity, including specific
performance.
(d)    If this Agreement is terminated pursuant to Section 14.1 for any reason
(other than as set forth in Section 14.2(b), Section 14.2(c) or the following
proviso), neither Buyer nor Seller shall have any liability or obligation to the
other Party in connection with the termination of this Agreement, and the
Parties shall instruct the Escrow Agent to return the Deposit to Buyer (free and
clear of any claims thereon by Seller) within five Business Days of the
termination date; provided, however, that if this Agreement is terminated by
Seller pursuant to Section 14.1(f), Seller shall have the right to seek actual
damages (incurred by Seller) against Buyer as a result of Buyer’s breach of
Section 3.2. If a Party is otherwise entitled to the Deposit under this Section
14.2, the Parties shall instruct the Escrow Agent to release the Deposit to the
applicable Party within five Business Days of the termination date.
14.3    Return of Documentation and Confidentiality. Upon termination of this
Agreement, Buyer shall destroy or return to Seller all title, engineering,
geological and geophysical data, environmental assessments and/or reports, maps
and other information furnished by or on behalf of Seller to Buyer or prepared
by or on behalf of Buyer in connection with its due diligence investigation of
the Conveyed Interests, in each case, in accordance with the Confidentiality
Agreement and, if Buyer elects to destroy any such information, an officer of
Buyer shall certify the destruction of such information to Seller in writing.
ARTICLE XV
MISCELLANEOUS
15.1    Appendices, Exhibits and Schedules. All of the Appendices, Exhibits and
Schedules referred to in this Agreement are hereby incorporated into this
Agreement by reference and constitute a part of this Agreement. Each Party to
this Agreement and its counsel have received a complete set of Appendices,
Exhibits and Schedules prior to and as of the execution of this Agreement.
15.2    Expenses and Taxes.
(a)    Except as otherwise specifically provided herein, 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)    Seller shall be allocated and bear all Asset Taxes for any period or
portion thereof ending prior to the Effective Time, and Buyer shall be allocated
and bear all Asset Taxes for any period or portion thereof that begins at or
after the Effective Time.

66

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

(c)    For purposes of Section 15.2(b), (i) Asset Taxes that are attributable to
the severance or production of Hydrocarbons shall be allocated to the period in
which the severance or production giving rise to such Asset Taxes occurred, (ii)
Asset Taxes that are based upon or related to income or receipts or imposed on a
transactional basis (other than such Asset Taxes described in clause (i) or
(iii)), shall be allocated to the period in which the transaction giving rise to
such Asset Taxes occurred, and (iii) Asset Taxes that are ad valorem, property
or other Asset Taxes imposed on a periodic basis pertaining to a Straddle Period
shall be allocated between the portion of such Straddle Period ending
immediately prior to the Effective Time and the portion of such Straddle Period
beginning at the Effective Time by prorating each such Asset Tax based on the
number of days in the applicable Straddle Period that occur before the date on
which the Effective Time occurs, on the one hand, and the number of days in such
Straddle Period that occur on or after the date on which the Effective Time
occurs, on the other hand. For purposes of clause (iii) of the preceding
sentence, the period for such Asset Taxes shall being on the date on which
ownership of the applicable Conveyed Interests gives rise to liability for the
particular Asset Tax and shall end on the day before the next such date. To the
extent the actual amount of an Asset Tax is not known at the time an adjustment
is to be made with respect to such Asset Tax pursuant to Section 3.3, the
Parties shall utilize the most recent information available in estimating the
amount of such Asset Tax for purposes of such adjustment. To the extent the
actual amount of an Asset Tax is ultimately determined to be different than the
amount (if any) that was taken into account in the Final Settlement Statement as
finally determined pursuant to Section 3.6, Seller shall indemnify and hold
harmless Buyer for any excess of actual amount of an Asset Tax over such
estimate, and Buyer shall indemnify and hold harmless Seller for any excess of
such estimate over the actual amount of Asset Tax, in each case taking into
account the amount of such Asset Tax that is allocable to such Party under
Section 15.2(b) and this Section 15.2(c). Subject to the Transition Services
Agreement (if applicable), Buyer shall be responsible for the preparation and
timely filing of any Tax Returns with respect to Asset Taxes for Tax periods
beginning at or after the Effective Time that are required to be filed on or
after the Closing Date, and the payment to the applicable Taxing Authority of
all Asset Taxes for such Tax periods that become due and payable on or after the
Closing Date, and Buyer shall indemnify and hold Seller harmless for any failure
to file such Tax Returns and to make such payments subject to Buyer’s right of
reimbursement for any Asset Taxes for which Seller is responsible pursuant to
Section 15.2(b) and this Section 15.2(c). Notwithstanding the foregoing
regarding filing and payment, Seller shall be responsible for the preparation
and timely filing of any Tax Return and the payment to the applicable Taxing
Authority of any ad valorem or property taxes on Seller operated Subject
Properties which are due and payable within the calendar year 2017, with the
prior written consent of Buyer (not to be unreasonably withheld, conditioned or
delayed) and subject to each Party’s right of reimbursement for any such taxes
for which Seller is responsible pursuant to this Agreement; provided, however,
that Buyer will be deemed to have given prior written consent in any case where
the actual ad valorem or property taxes which are due and payable are not
materially different from those provided in the Preliminary Settlement
Statement, as agreed on by the Parties pursuant to Section 3.5.
(d)    All required documentary, filing and recording fees and expenses in

respect to the transactions described in this Agreement (collectively, “Transfer
Taxes”) shall be borne by Buyer; provided that Seller shall pay or cause to be
paid to the applicable Governmental Authorities any Transfer Taxes that it is
required by Law to collect and remit. Buyer shall indemnify and hold Seller
harmless from and against such Transfer Taxes within 30 days of Seller’s written
demand therefor. If Seller (not Buyer) is required by applicable Law to appeal
or protest the assessment of Transfer Taxes, the appeal or protest of such
proposed assessment shall be treated as an item for which Seller is entitled to
indemnification and if Buyer provides a written request and instructs Seller to
do so, Seller shall prosecute the protest or appeal; in such event Buyer shall
pay all out-of-pocket expenses of Seller (including attorneys’ fees) incurred by
Seller in connection with such appeal or protest. Seller and Buyer shall
reasonably cooperate in good faith to minimize, to the extent permissible under
applicable Law, the amount of any such Transfer Taxes.
(e)    The Parties shall cooperate fully, as and to the extent reasonably
requested by the other Party, in connection with the filing of Tax Returns and
any audit, litigation, or other proceeding with respect to Taxes relating to the
Conveyed Interests. Such cooperation shall include the retention and (upon
another Party’s request) the provision of records and information that are
relevant to any such Tax Return or audit, litigation or other proceeding and
making employees available on a mutually convenient basis to provide additional
information and explanation of any material provided under this Agreement. The
Parties agree to retain all books and records with respect to Tax matters
pertinent to the Conveyed Interests relating to any Tax period beginning before
the Closing Date until the later of (i) seven years or (ii) sixty days following
the expiration of the statute of limitations of the respective Tax periods and
to abide by all record retention agreements entered into with any Governmental
Authority.
15.3    Assignment. Subject to the provisions of Section 15.18, this Agreement
may not be assigned by either Party without the prior written consent of the
other Party. In the event a Party consents to any such assignment, such
assignment shall not relieve the assigning Party of any obligations and
responsibilities hereunder, including obligations and responsibilities arising
following such assignment. Any assignment or other transfer by Buyer or its
successors and assigns of any of the Conveyed Interests shall not relieve Buyer
or its successors or assigns of any of their obligations (including indemnity
obligations) hereunder, as to the Conveyed Interests so assigned or transferred.
15.4    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.
15.5    Publicity. Seller and Buyer shall promptly consult with each other with
regard to all press releases or other public or private announcements issued or
made at or prior to Closing concerning this Agreement or the transactions
contemplated herein, and, except as may be required by applicable Laws or the
applicable rules and regulations of any Governmental Authority or stock exchange
or as described in the remaining provisions of this Section 15.5, neither Buyer
nor Seller shall issue any such press release or other public or private
announcement without the prior written consent of the other Party (which shall
not be unreasonably withheld, conditioned, or delayed). The Parties shall be
obligated to hold all specific terms and provisions of this Agreement strictly

68

Agreement; provided, however, that the foregoing shall not (a) restrict

disclosures shall be made only to the extent required thereunder, (b) prevent

or state assignments delivered at Closing or from complying with any disclosure
requirements of Governmental Authorities that are applicable to the transfer of
the Conveyed Interests from Seller to Buyer, (c) 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
Confidentiality Agreement so long as such Person continues to hold such
information confidential on the same terms as set forth in this Section 15.5,

transactions contemplated hereby.

Exchange. Each Party agrees to use reasonable efforts to cooperate with the
other Party in the completion of such an Exchange including an Exchange subject
to the procedures outlined in Treasury Regulation § 1.1031(k)‑1 and/or Internal
Revenue Service Revenue Procedure 2000‑37. Each of Seller and Buyer shall have
the right at any time prior to Closing to assign all or a part of its rights

Treasury Regulation § 1.1031(k)‑1(g)(4)(iii)) or an exchange accommodation
titleholder (as that term is defined in Internal Revenue Service Revenue
Procedure 2000‑37) to effect an Exchange. In connection with any such Exchange,
any exchange accommodation titleholder shall have taken all steps necessary to
own the Conveyed Interests under applicable Law.  Each Party acknowledges and
agrees that neither an assignment of a Party’s rights under this Agreement nor
any other actions taken by a Party or any other Person in connection with the
Exchange shall release either Party from, or modify, any of its liabilities and
obligations (including indemnity obligations to the other Party) under this
Agreement, and neither Party makes any representations as to any particular Tax
treatment that may be afforded to any other Party by reason of such assignment
or any other actions taken in connection with the Exchange.  Either Party
electing to treat the acquisition or sale of the Conveyed Interests as an
Exchange shall be obligated to pay all additional costs incurred hereunder as a
result of the Exchange, and in consideration for the cooperation of the other
Party, the Party electing Exchange treatment shall agree to pay all costs
associated with the Exchange and to indemnify and hold the other Party, its
Affiliates, and their respective former, current and future partners, members,
shareholders, owners, officers, directors, managers, employees, agents and
representatives harmless from and against any and all liabilities and Taxes
arising out of, based upon, attributable to or resulting from the Exchange or
transactions or actions taken in connection with the Exchange that would not
have been incurred by the other Party but for the electing Party’s Exchange
election.
15.19    Specific Performance. The Parties agree that if any of the provisions
of this Agreement are not performed by a Party in accordance with their specific
terms, the other Party shall be entitled to specific performance of the terms
hereof, in addition to any other remedy available at law or in equity; provided,
that, for the avoidance of doubt, if this Agreement is terminated pursuant to
Article XIV, a Party may not thereafter seek or otherwise attempt to enforce
specific performance of the closing of the transactions contemplated hereby.

to defaulting co‑owners under applicable operating agreements;
