        (f)    all
trade credits, account receivables, note receivables, take-or-pay amounts receivable, and other receivables attributable to the Assets with
respect to any period of time prior to the Effective Time; 

        (g)   all

        (i)    all
rights, titles, claims and interests of Seller or any Affiliate of Seller (i) to or under any policy or agreement of insurance or any insurance proceeds;

        (j)    subject
to Section 12.5, any patent, patent application, logo, service mark, copyright, trade name or trademark of
or associated with Seller or any Affiliate of Seller or any business of Seller or of any Affiliate of Seller; 

        (k)   a
nonexclusive right to freely use any copies of any logs, interpretive data, technical outputs, technical evaluations, maps, engineering data and reports, reserve
studies and evaluations, and other data and information being transferred as a part of the Assets that Seller is entitled to retain pursuant to  Section 1.5; and 

        (l)    all
Retained Assets not conveyed to Purchaser pursuant to Section 7.7 and any Property excluded pursuant to  Section 3.4(d)(iii). 

 Section 1.4 Effective Time; Proration of Costs and Revenues. 

        (a)   Subject
to Section 1.5, possession of the Assets shall be transferred from Seller to Purchaser at the Closing, but
certain financial benefits and burdens of the Assets shall be transferred effective as of 7:00 A.M., local time, where the respective Assets are located, on November 1, 2006 (the
"Effective Time"), as described below. 

3

 

        (b)   Purchaser
shall be entitled to all Hydrocarbon production from or attributable to the Properties at and after the Effective Time (and all products and proceeds
attributable thereto), and to all other income, proceeds, receipts and credits earned with respect to the Assets at or after the Effective Time, and shall be responsible for (and entitled to any
refunds with respect to) all Property Costs incurred at and after the Effective Time. Seller shall be entitled to all Hydrocarbon production from or attributable to the Properties prior to the
Effective Time (and all products and proceeds attributable thereto), and to all other income, proceeds, receipts and credits earned with respect to the Assets prior to the Effective Time, and shall be
responsible for (and entitled to any refunds with respect to) all Property Costs incurred prior to the Effective Time. "Earned" and "incurred", as used in this Agreement, shall be interpreted in
accordance with GAAP and Council of Petroleum Accountants Society (COPAS) standards, as applicable. "Property Costs" means all costs attributable to the ownership and operation of the Assets
(including without limitation costs of insurance relating specifically to the Assets and ad valorem, property, severance, Hydrocarbon production and similar Taxes based upon or measured by the
ownership or operation of the Assets or the production of Hydrocarbons therefrom, but excluding any other Taxes) and capital expenditures incurred in the ownership and operation of the Assets in the
ordinary course of business and, where applicable, in accordance with the relevant operating or unit agreement, if any, and overhead costs charged to the Assets under the relevant operating agreement
or unit agreement, if any, or, if none, the amounts shown under Schedule 1.4 shall be the overhead amounts deemed charged to the Assets, but
excluding without limitation liabilities, losses, costs, and expenses attributable to (i) claims for personal injury or death, property damage or violation of any Law, (ii) obligations
to plug wells or dismantle, abandon and salvage facilities, (iii) obligations to remediate any contamination of groundwater, surface water, soil, Equipment or Pipelines under applicable
Environmental Laws, (iv) obligations to furnish make-up gas according to the terms of applicable gas sales, gathering or transportation contracts, (v) gas balancing
obligations and (vi) obligations to pay working interests, royalties, overriding royalties or other interests held in suspense, all of which are addressed in  Article 11 or elsewhere in this
Agreement. For purposes of this Section 1.4, determination
of whether Property Costs are attributable to the period before or after the Effective Time shall be based on when services are rendered, when the goods are delivered, or when the work is performed.
For clarification, the date an item or work is ordered is not the date of a pre-Effective Time transaction for settlement purposes, but rather the date on which the item ordered is
delivered to the job site, or the date on which the work ordered is performed, shall be the relevant date. For purposes of allocating Hydrocarbon production (and accounts receivable with respect
thereto), under this Section 1.4, (i) liquid Hydrocarbons shall be deemed to be "from or attributable to" the Properties when they are
placed into the storage facilities and (ii) gaseous Hydrocarbons shall be deemed to be "from or attributable to" the Properties when they pass through the delivery point sales meters on the
pipelines through which they are transported. Seller shall utilize reasonable interpolative procedures to arrive at an allocation of Hydrocarbon production when exact meter readings or gauging and
strapping data is not available. Seller shall provide to Purchaser, no later than five (5) Business Days prior to Closing, all data necessary to support any estimated allocation, for purposes
of establishing the adjustment to the Purchase Price pursuant to Section 2.2 hereof that will be used to determine the Closing Payment. Property
Costs that are paid periodically shall be prorated based on the number of days in the applicable period falling before and the number of days in the applicable period falling at or after the Effective
Time, except that Hydrocarbon production, severance and similar Taxes shall be prorated based on the number of units actually produced, purchased or sold or proceeds of sale, as applicable, before,
and at or after, the Effective Time. In each case, Purchaser shall be responsible for the portion allocated to the period at and after the Effective Time and Seller shall be responsible for the
portion allocated to the period before the Effective Time. 

4

 

 Section 1.5 Delivery and Maintenance of Records. 

        Seller,
at Seller's sole cost and expense, shall deliver the Records (FOB Seller's office) to Purchaser within thirty (30) days following Closing;  provided, however, that Seller shall be entitled to retain those original Records necessary to comply
with its obligations under the Transition Services Agreement for so long as is reasonably necessary to comply with its obligations under the Transition Services Agreement and Seller, at Purchaser's
sole expense, shall provide Purchaser with copies of any such original Records retained by Seller as soon as reasonably practicable. Other than any original Records retained by Seller pursuant to  Section 1.2(i)
, Purchaser shall be entitled to all original Records maintained by Seller (other than such Records maintained at
the Grogans Mill offsite storage facility, which is addressed below), a scanned copy of all of the original Records and, to the extent available and specifically identifiable to the Assets, original
Records maintained by Seller at its Grogans Mill offsite storage facility. Seller shall be entitled to keep a copy or copies of all Records; provided, however, that Seller shall not sell or otherwise
allow third parties to review, copy or otherwise use any Records retained by Seller. Purchaser shall preserve the Records for a period of ten (10) years following the Closing and will allow
Seller and its representatives, consultants and advisors reasonable access, during normal business hours and upon reasonable notice, to the Records for any legitimate business reason of Seller,
including in order for Seller to comply with a Tax or other legally required reporting obligation or Tax or legal dispute; provided, however, that Purchaser shall not be required to grant access to
Seller or any of its representative, consultants or advisors, to any Records that are subject to an attorney/client or attorney work product privilege or that would cause Purchaser to violate any
obligation to any third party or breach any restriction legally binding on Purchaser. Any such access shall be at the sole cost and expense of Seller. Unless otherwise consented to in writing by
Seller, for a period of ten (10) years following the Closing Date, Purchaser shall not and shall cause its Affiliates not to, destroy, alter or otherwise dispose of the Records, or any portions
thereof, without first giving at least thirty (30) days prior written notice to Seller and offering to surrender to Seller the Records or such portions thereof. 

ARTICLE 2

Purchase Price  

 Section 2.1 Valuation of Assets. 

        The
purchase price for the Assets (the "Purchase Price") shall be $1,600,000,000 adjusted as provided in Section 2.2. 

 Section 2.2 Adjustments to Agreed Asset Value. 

        The
Purchase Price for the Assets shall be adjusted in the manner specified below (without duplication), with all such amounts being determined in accordance with GAAP and Council of
Petroleum Accountants Society (COPAS) standards, as applicable, in order to reach the Adjusted Purchase Price: 

        (a)   Reduced
by the aggregate amount of the following proceeds received by Seller between (and including) the Effective Time and the Closing Date (with the period between the
Effective Time and the Closing Date referred to as the "Adjustment Period"): (i) proceeds from the sale of Hydrocarbons (net of any royalties, overriding royalties or other burdens on or
payable out of production, gathering, processing and transportation costs and any production, severance, sales, excise or similar Taxes not reimbursed to Seller by the purchaser of production)
produced from or attributable to the Properties during the Adjustment Period, and (ii) other proceeds earned with respect to the Assets during the Adjustment Period; 

        (b)   Reduced
to the extent provided in Section 7.7 with respect to Preference Rights and Retained Assets; 

5

 

        (c)   (i) If
the parties make the election under Section 3.4(d)(i) with respect to a Title Defect, subject to the
Individual Title Deductible and the Aggregate Defect Deductible, reduced by the Title Defect Amount with respect to such Title Defect if the Title Defect Amount has been determined prior to Closing
and (ii) subject to the Individual Benefit Deductible and the Aggregate Benefit Deductible, increased by the Title Benefit Amount with respect to each Title Benefit for which the Title Benefit
Amount has been determined prior to Closing; 

        (d)   Increased
by the amount of all Property Costs and other costs attributable to the ownership and operation of the Assets which are paid by Seller and incurred during the
Adjustment Period (including any overhead costs under Schedule 1.4 deemed charged to the Assets with respect to the Adjustment Period even though
not actually paid), except any Property Costs and other such costs already deducted in the determination of proceeds in Section 2.2(a); 

        (e)   Reduced
to the extent provided in Section 3.4(d)(iii) for any Properties excluded from the Assets pursuant to  Section 3.4(d)(iii) and reduced to the
extent provided in Section 4.3 for Environmental
Defects; 

        (f)    Reduced
by the aggregate amounts payable to owners of working interests, royalties and overriding royalties and other interests in the Properties held in suspense by
Seller as of the Closing Date; 

        (g)   Increased
or reduced as mutually agreed upon in writing prior to Closing by Seller and Purchaser; 

        (h)   Increased
by the value of the amount of merchantable Hydrocarbons stored in tanks and pipelines attributable to the ownership and operation of the Assets that belong to
Seller as of the Effective Time (which value shall be computed at the applicable third-party contract prices for the month of October 2006 for such stored Hydrocarbons); 

        (i)    Reduced
by the actual net aggregate Imbalances, if any, owed by Seller to third-parties, as of the Effective Time, multiplied by a price of $5.00 per MMBtu; 

        (j)    Reduced
by $4,322,000 on account of the Hedging Transactions; and 

        (k)   Reduced
by any amount determined to be owed by Seller pursuant to Section 7.16. 

        Each
adjustment made pursuant to Section 2.2(a) shall serve to satisfy, up to the amount of the adjustment, Purchaser's entitlement
under Section 1.4 to Hydrocarbon production from or attributable to the Properties during the Adjustment Period, and to the value of other
income, proceeds, receipts and credits earned with respect to the Assets during the Adjustment Period, and as such, Purchaser shall not have any separate rights to receive any Hydrocarbon production
or income, proceeds, receipts and credits with respect to which an adjustment has been made. Similarly, the adjustment described in  Section 2.2(d) shall serve to satisfy, up to the amount of the
adjustment, Purchaser's obligation under  Section 1.4 to pay Property Costs and other costs attributable to the ownership and operation of the Assets which are incurred during the
Adjustment Period, and as such, notwithstanding anything in this Agreement to the contrary, Purchaser shall not be separately obligated to pay for any Property Costs or other such costs with respect
to which an adjustment has been made. 

        The
Purchase Price less the Deposit provided for in Section 2.4, adjusted as set forth in (a) through (j), shall be
increased by simple interest thereon from the Effective Time to the Closing Date, computed at the Agreed Interest Rate. 

6

 

 Section 2.3 Allocation of Purchase Price for Tax Purposes  

        Purchaser and Seller will use commercially reasonable efforts to agree, on or before the Closing Date, upon an allocation of the unadjusted Purchase Price among
each of the Assets, in compliance with the principles of Section 1060 of the Code, and the Treasury regulations thereunder. Such allocation of value shall be generally treated as Class V
assets for purposes of Internal Revenue Service Form 8594 to the extent possible consistent with the character of the Assets involved. The "Tax Allocated Value" for any Asset equals the portion
of the unadjusted Purchase Price to be allocated to such Asset by the parties pursuant to this Section 2.3, increased or reduced as described in
this Article 2. Any adjustments to the Purchase Price other than the adjustments provided for in Sections 2.2(b),
2.2(c) and 2.2(e) shall be applied on a pro rata basis to the amounts agreed to by the parties pursuant to this  Section 2.3
for all Assets to the maximum extent possible consistent with the character of the adjustments. After all such adjustments are made,
any adjustments to the Purchase Price pursuant to Sections 2.2(b), 2.2(c) and 2.2(e) shall be applied to
the amounts agreed to by the parties pursuant to this Section 2.3 for the particular affected Assets. After Seller and Purchaser have agreed on
the Tax Allocated Values for the Assets, Seller will be deemed to have accepted such Tax Allocated Values for purposes of this Agreement and the transactions contemplated hereby, but otherwise makes
no representation or warranty as to the accuracy of such values. Seller and Purchaser agree (i) that the Tax Allocated Values shall be used by Seller and Purchaser as the basis for reporting
asset values and other items for purposes of all federal, state, and local Tax Returns, including without limitation Internal Revenue Service Form 8594 and (ii) that neither they nor
their Affiliates will take positions inconsistent with the Tax Allocated Values in notices to Governmental Bodies, in audit or other proceedings with respect to Taxes unless required by applicable Law
or with the consent of the other party. Purchaser and Seller agree that each shall furnish the other a copy of Form 8594 (Asset Acquisition Statement under Section 1060) proposed to be
filed with the Internal Revenue Service by such party or any Affiliate thereof within ten (10) days prior to such filing. 

 Section 2.4 Deposit  

        Concurrently with the execution of this Agreement, Purchaser has paid to Seller an earnest money deposit in an amount equal to $80,000,000 (the "Deposit"). The
Deposit shall be non-interest bearing and applied against the Purchase Price if the Closing occurs or shall be otherwise distributed in accordance with the terms of this Agreement. 

ARTICLE 3

TITLE MATTERS  

 Section 3.1 Seller's Title. 

        (a)   Except
for the special warranty of title referenced in Section 3.1(b) and without limiting Purchaser's right to
adjust the Purchase Price by operation of this Article 3, Seller makes no warranty or representation, express, implied, statutory or otherwise,
with respect to Seller's title to any of the Assets, and Purchaser hereby acknowledges and agrees that the sole remedy for any defect of title, including any Title Defect, with respect to any of the
Assets (i) before Closing, shall be as set forth in Section 3.4(d) and (ii) after Closing, shall be pursuant to the special
warranty of title referenced in Section 3.1(b). 

        (b)   The
conveyance to be delivered by Seller to Purchaser shall be substantially in the form of Exhibit B hereto (the
"Conveyance") and contain a special warranty of Defensible Title by, through and under Seller and its Affiliates, but not otherwise, to the Units, Warranty Wells and other Assets shown on  Exhibit A-1, subject to the Permitted Encumbrances, but shall otherwise be without warranty of title of any kind, express, implied or
statutory or otherwise. 

7

   
        (c)   Purchaser shall not be entitled to protection under Seller's special warranty of title in the Conveyance against any Title Defect reported by Purchaser under  Section 3.4(a) and/or any Title Defect actually known by any officer of Purchaser or any of its Affiliates prior to the Title Claim Date. 

        (d)   Notwithstanding
anything herein provided to the contrary, if a Title Defect under this Article 3 results from any
matter which could also result in the breach of any representation or warranty of Seller set forth in Article 5, then Purchaser shall only be
entitled to assert such matter (i) before Closing, as a Title Defect to the extent permitted by this Article 3, or (ii) after
Closing, as a breach of Seller's special warranty of title contained in the Conveyance to the extent permitted by this Section 3.1, and shall be
precluded from also asserting such matter as the basis of the breach of any such representation or warranty. 

 Section 3.2 Definition of Defensible Title. 

        As
used in this Agreement, the term "Defensible Title" means that title of Seller with respect to the Units, Warranty Wells or other Assets shown in  Exhibit A-1 that, except for and subject to
Permitted Encumbrances: 

        (a)   Entitles
Seller to receive a share of the Hydrocarbons produced, saved and marketed from any Unit, Warranty Well or other Asset shown in  Exhibit A-1 throughout the duration of the productive life of such
Unit, Warranty Well or other Asset (after satisfaction of all
royalties, overriding royalties, net profits interests or other similar burdens on or measured by production of Hydrocarbons) (a "Net Revenue Interest"), of not less than the Net Revenue Interest
shown in Exhibit A-1 for such Unit, Warranty Well or other Asset, except (solely to the extent that such actions do not cause a
breach of Seller's covenants under Section 7.6) for decreases in connection with those operations in which Seller may from and after the
Effective Time become a non-consenting co-owner, decreases resulting from the establishment or amendment from and after the Effective Time of pools or units, and decreases
required to allow other working interest owners to make up past underproduction or pipelines to make up past under deliveries, and except as stated in such  Exhibit A-1; 

        (b)   Obligates
Seller to bear a percentage of the costs and expenses for the maintenance and development of, and operations relating to, (i) any Unit, Warranty Well or
other Asset shown in Exhibit A-1 not greater than the "working interest" shown in  Exhibit A-1 for such Unit, Warranty Well or other Asset without
increase throughout the productive life of such Unit, Warranty Well
or other Asset, except as stated in Exhibit A-1 and except for increases resulting from contribution requirements with respect to
non-consenting co-owners under applicable operating agreements and increases that are accompanied by at least a proportionate increase in Seller's Net Revenue Interest; and 

        (c)   Is
free and clear of liens, encumbrances, obligations, security interests, irregularities, pledges, or other defects. 

        (d)   As
used in this Agreement, the term "Title Defect" means any lien, charge, encumbrance, obligation (including contract obligation), defect, or other matter (including
without limitation a discrepancy in Net Revenue Interest or working interest) that causes Seller not to have Defensible Title in and to the Units, Warranty Wells or other Assets shown on  Exhibit A-1 as of the Effective Time and the Closing. As used in this Agreement, the term "Title Benefit" shall mean any right,
circumstance or condition that operates to increase the Net Revenue Interest of Seller in any Unit, Warranty Well or other Asset shown on  Exhibit A-1, without causing a greater than proportionate
increase in Seller's working interest above that shown in  Exhibit A-1 as of the Effective Time. Notwithstanding the foregoing, the following shall not be considered Title Defects: 

	(i)
	defects
based solely on (1) lack of information in Seller's files, or (2) references to a document(s) if such document(s) is not in Seller's files; 

8

 

	(ii)
	defects
arising out of lack of corporate or other entity authorization unless Purchaser provides affirmative evidence that the action was not authorized;

	(iii)
	defects
based on failure to record Leases issued by any state or federal Governmental Body, or any assignments of such Leases, in the real property, conveyance or
other records of the parish in which such Property is located;

	(iv)
	defects
based on a gap in Seller's chain of title in the parish records as to fee Leases, unless such gap is affirmatively shown to exist in such records by an abstract
of title, title opinion or landman's title chain which documents shall be included in a Title Defect Notice; and

	(v)
	defects
that have been cured by applicable Laws of limitation or prescription. 

 Section 3.3 Definition of Permitted Encumbrances. 

        As
used herein, the term "Permitted Encumbrances" means any or all of the following: 

        (a)   Royalties
and any overriding royalties, reversionary interests and other burdens, to the extent that any such burden does not reduce Seller's Net Revenue Interest below
that shown in Exhibit A-1 or increase Seller's working interest above that shown in  Exhibit A-1 without a proportionate increase in the Net
Revenue Interest; 

        (b)   All
Leases, unit agreements, pooling agreements, operating agreements, Hydrocarbon production sales contracts, division orders and other contracts, agreements and
instruments applicable to the Assets, to the extent that they do not, individually or in the aggregate, reduce Seller's Net Revenue Interest below that shown in  Exhibit A-1 or increase Seller's
working interest above that shown in  Exhibit A-1 without a proportionate increase in the Net Revenue Interest; 

        (c)   Preference
Rights applicable to this or any future transaction; 

        (d)   Transfer
Requirements applicable to this or any future transaction; 

        (e)   Liens
for current Taxes or assessments not yet delinquent; 

        (f)    Materialman's,
mechanic's, repairman's, employee's, contractor's, operator's and other similar liens or charges arising in the ordinary course of business for amounts
not yet delinquent (including any amounts being withheld as provided by Law); 

        (g)   All
rights to consent by, required notices to, filings with, or other actions by Governmental Bodies in connection with the sale or conveyance of the Assets or interests
therein pursuant to this or to any future transaction if they are not required or customarily obtained prior to the sale or conveyance; 

        (h)   Rights
of reassignment arising upon final intention to abandon or release the Assets, or any of them; 

        (i)    Easements,
rights-of-way, servitudes, permits, surface leases and other rights in respect of surface operations, to the extent that they do not
(i) reduce Seller's Net Revenue Interest below that shown in Exhibit A-1, (ii) increase Seller's working interest above
that shown in Exhibit A-1 without a proportionate increase in Net Revenue Interest, or (iii) detract in any material respect
from the value of, or interfere in any material respect with the use, ownership or operation of, the Assets subject thereto or affected thereby (as currently used, owned and operated) and which would
be acceptable by a reasonably prudent purchaser engaged in the business of owning and operating oil and gas properties; 

        (j)    Calls
on Hydrocarbon production under existing Contracts that are listed on Schedule 1.2(d); 

9

 

        (k)   All
rights reserved to or vested in any Governmental Body to control or regulate any of the Assets in any manner, and all obligations and duties under all applicable
Laws or under any franchise, grant, license or permit issued by any such Governmental Body; 

        (l)    Any
encumbrance on or affecting the Assets which is discharged by Seller at or prior to Closing; 

        (m)  Any
matters shown on Exhibit A-1; 

        (n)   Any
other liens, charges, encumbrances, defects or irregularities which do not, individually or in the aggregate, detract in any material respect from the value of, or
interfere in any material respect with the use or ownership of, the Assets subject thereto or affected thereby (as currently used or owned), which would be accepted by a reasonably prudent purchaser
engaged in the business of owning and operating oil and gas properties, and which do not reduce Seller's Net Revenue Interest below that shown in  Exhibit A-1, or increase Seller's working interest
above that shown in  Exhibit A-1 without a proportionate increase in Net Revenue Interest; 

        (o)   Matters
that would otherwise be considered Title Defects but that do not meet the Individual Title Deductible set forth in  Section 3.4(j); 

        (p)   Imbalances
associated with the Assets; and 

        (q)   Liens
granted under applicable joint operating agreements. 

 Section 3.4 Notice of Title Defect Adjustments. 

        (a)   To
assert a claim of a Title Defect prior to Closing, Purchaser must deliver claim notices to Seller (each a "Title Defect Notice") on or before March 1, 2007
(the "Title Claim Date"); provided, however, that Purchaser agrees that it shall furnish Seller once every two (2) weeks until the Title Claim Date with a Title Defect Notice if any officer of
Purchaser or its Affiliates discover or learn of any Title Defect during such two (2) week period. Each Title Defect Notice shall be in writing and shall include (i) a description of the
alleged Title Defect(s), (ii) the Units, Warranty Wells or other Assets in Exhibit A-1 affected by the Title Defect (each a
"Title Defect Property"), (iii) the Allocated Value of each Title Defect Property, (iv) supporting documents reasonably necessary for Seller (as well as any title attorney or examiner
hired by Seller) to verify the existence of the alleged Title Defect(s), and (v) the amount by which Purchaser reasonably believes the Allocated Value of each Title Defect Property is reduced
by the alleged Title Defect(s) and the computations and information upon which Purchaser's belief is based. Notwithstanding any other provision of this Agreement to the contrary, but subject to
Purchaser's rights in connection with the special warranty of title referenced in Section 3.1(b), Purchaser shall be deemed to have waived its
right to assert Title Defects of which Seller has not been given notice on or before the Title Claim Date. For purposes hereof, the "Allocated Value" of an Asset shall mean the portion of the Purchase
Price that has been allocated to a particular Unit, Warranty Well or other Asset in Exhibit A-1. 

        (b)   Seller
shall have the right, but not the obligation, to deliver to Purchaser on or before the Title Claim Date, with respect to each Title Benefit, a notice (a "Title
Benefit Notice") including (i) a description of the Title Benefit, (ii) the Units, Warranty Wells or other Assets in  Exhibit A-1 affected, (iii) the Allocated Values of the Units,
Warranty Wells or other Assets in  Exhibit A-1 subject to such Title Benefit and (iv) the amount by which Seller reasonably believes the Allocated Value of those
Units, Warranty Wells or other Assets is increased by the Title Benefit, and the computations and information upon which Seller's belief is based. Seller shall be deemed to have waived all Title
Benefits of which it has not given notice to Purchaser on or before the Title Claim Date. 

10

 

        (c)   Seller
shall have the right, but not the obligation, to attempt, at its sole cost, to cure or remove at any time prior to Closing (the "Cure Period"), unless the parties
otherwise agree, any Title Defects of which it has been advised in writing by Purchaser. 

        (d)   Remedies
for Title Defects. 

        In
the event that any Title Defect is not waived by Purchaser or cured on or before Closing, Purchaser and Seller shall mutually elect to have one of the following remedies apply: 

	(i)
	subject
to the Individual Title Deductible and the Aggregate Defect Deductible, have the Purchase Price reduced by an amount agreed upon ("Title Defect Amount") pursuant
to Section 3.4(g) or Section 3.4(i) by Purchaser and Seller as being the value of such
Title Defect, taking into consideration the Allocated Value of the Property subject to such Title Defect, the portion of the Property subject to such Title Defect and the legal effect of such Title
Defect on the Property affected thereby; provided, however, that the methodology, terms and conditions of Section 3.4(g) shall control any such
determination;

	(ii)
	indemnify
Purchaser against all liability, loss, cost and expense resulting from such Title Defect pursuant to an indemnity agreement (the "Indemnity Agreement") in the
form attached hereto as Exhibit C; or

	(iii)
	have
Seller retain the entirety of the Property that is subject to such Title Defect, together with all associated Assets, in which event the Purchase Price shall be
reduced by an amount equal to the Allocated Value of such Property. 

In
the event that Purchaser and Seller cannot mutually agree upon one of the foregoing remedies with respect to a Title Defect asserted by Purchaser pursuant to  Section 3.4(a) prior to Closing, then
Seller shall, at its sole election, select the remedy set forth in subsection (i) or
(iii) above as the remedy for such Title Defect. 

        (e)   With
respect to each Unit, Warranty Well or other Asset in Exhibit A-1 affected by Title Benefits
reported under Section 3.4(b), subject to the Individual Benefit Deductible and the Aggregate Defect Deductible, the Purchase Price shall be
increased by an amount (the "Title Benefit Amount") equal to the increase in the Allocated Value for such Unit, Warranty Well or other Asset in  Exhibit A-1 caused by such Title Benefits, as
determined pursuant to  Section 3.4(h). 

        (f)    Section 3.4(d) shall be the exclusive right and remedy of Purchaser with respect to Title Defects asserted by
Purchaser pursuant to Section 3.4(a). 

        (g)   The
Title Defect Amount resulting from a Title Defect shall be the amount by which the Allocated Value of the Title Defect Property is reduced as a result of the
existence of such Title Defect and shall be determined in accordance with the following methodology, terms and conditions: 

	(i)
	if
Purchaser and Seller agree on the Title Defect Amount, that amount shall be the Title Defect Amount;

	(ii)
	if
the Title Defect is a lien, encumbrance or other charge which 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 the Title Defect Property;

	(iii)
	if
the Title Defect represents a discrepancy between (A) the Net Revenue Interest for any Title Defect Property and (B) the Net Revenue Interest stated
on Exhibit A-1, 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 stated on  Exhibit A-1; 

11

 

	(iv)
	if
the Title Defect represents an obligation, encumbrance, burden or charge upon or other defect in title to the Title Defect Property of a type not described in
subsections (i), (ii) or (iii) above, the Title Defect Amount shall be determined by taking into account the Allocated Value of the Title Defect Property, the portion of the Title Defect
Property affected by the Title Defect, the legal effect of the Title Defect, the potential economic effect of the Title Defect over the life of the Title Defect Property, the values placed upon the
Title Defect by Purchaser and Seller and such other factors as are necessary to make a proper evaluation; and

	(v)
	notwithstanding
anything to the contrary in this Article 3, 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 the Title Defect Property. 

        (h)   The
Title Benefit Amount for any Title Benefit shall be the product of the Allocated Value of the affected Unit, Warranty Well or other Asset in  Exhibit A-1 multiplied by a fraction, the numerator of
which is the Net Revenue Interest increase and the denominator of which is the
Net Revenue Interest stated on Exhibit A-1. 

        (i)    Seller
and Purchaser shall attempt in good faith to agree on all Title Defect Amounts and Title Benefit Amounts prior to Closing. If Seller and Purchaser are unable to
agree by Closing, the Title Defect Amounts and Title Benefit Amounts in dispute shall be exclusively and finally resolved by arbitration pursuant to this  Section 3.4(i). There shall be a single
arbitrator, who shall be a title attorney with at least ten (10) years experience in oil and gas
titles involving properties in the regional area in which the Properties are located, as selected by mutual agreement of Purchaser and Seller within fifteen (15) Business Days after the end of
the Cure Period, and absent such mutual agreement, by the Houston office of the American Arbitration Association (the "Title Arbitrator"). The arbitration proceeding shall be held in Houston, Texas
and shall be conducted in accordance with the Commercial Arbitration Rules of the American Arbitration Association, to the extent such rules do not conflict with the terms of this Section. The Title
Arbitrator's determination shall be made within fifteen (15) Business Days after submission of the matters in dispute and shall be final and binding upon both parties, without right of appeal.
In making his determination, the Title Arbitrator shall be bound by the rules set forth in Section 3.4(g) and  Section 3.4(h) and may consider
such other matters as in the opinion of the Title Arbitrator are necessary or helpful to make a proper
determination. Additionally, the Title Arbitrator may consult with and engage disinterested third parties to advise the arbitrator, including without limitation petroleum engineers. The Title
Arbitrator shall act as an expert for the limited purpose of determining the specific disputed Title Defect Amounts and Title Benefit Amounts submitted by either party and may not award damages,
interest or penalties to either party with respect to any matter. Seller and Purchaser shall each bear its own legal fees and other costs of presenting its case. Each party shall bear
one-half of the costs and expenses of the Title Arbitrator, including any costs incurred by the Title Arbitrator that are attributable to such third party consultation. Within ten
(10) days after the Title Arbitrator delivers written notice to Purchaser and Seller of his award with respect to a Title Defect Amount or a Title Benefit Amount, (i) Purchaser shall pay
to Seller the amount, if any, so awarded by the Title Arbitrator to Seller, plus interest payable on such amount at the Agreed Interest Rate from (but not including) the Closing Date to (and
including) the date on which such amount is paid to Seller and (ii) Seller shall pay to Purchaser the amount, if any, so awarded by the Title Arbitrator to Purchaser, plus interest payable on
such amount at the Agreed Interest Rate from (but not including) the Closing Date to (and including) the date on which such amount is paid to Purchaser. 

12

 

        (j)    Notwithstanding
anything to the contrary, (i) in no event shall there be any adjustments to the Purchase Price or other remedies provided by Seller for any
individual uncured Title Defect for which the Title Defect Amount therefor does not exceed $100,000 ("Individual Title Deductible"); and (ii) in no event shall there be any adjustments to the
Purchase Price or other remedies provided by Seller for uncured Title Defects unless the aggregate Title Defect Amounts attributable to all uncured Title Defects, taken together with the aggregate
Environmental Defect Amounts attributable to all uncured Environmental Defects, exceeds a deductible in an amount equal to $32,000,000 ("Aggregate Defect Deductible"), after which point adjustments to
the Purchase Price or other remedies shall be made or available to Purchaser only with respect to uncured Title Defects and uncured Environmental Defects where the aggregate Title Defect Amounts and
Environmental Defect Amounts attributable are in excess of such Aggregate Defect Deductible. Notwithstanding anything to the contrary, (i) in no event shall there be any adjustments to the
Purchase Price for any individual Title Benefit for which the Title Benefit Amount does not exceed $100,000 ("Individual Benefit Deductible"); and (ii) in no event shall there be any
adjustments to the Agreed Asset Value for any Title Benefit unless the aggregate Title Benefit Amounts attributable to all such Title Benefits, exceeds a deductible in an amount equal to $32,0000,000
("Aggregate Benefit Deductible"), after which point adjustments to the Purchase Price shall be made only with respect to such Title Benefit Amounts in excess of such Aggregate Benefit Deductible. 

 Section 3.5 Casualty or Condemnation Loss. 

        (a)   From
and after the Effective Time, but subject to the provisions of Section 3.5(b) and  (c) below, Purchaser shall assume all risk of loss with respect to
and any change in the condition of the Assets and for production of Hydrocarbons
through normal depletion (including but not limited to the watering out of any Well, collapsed casing or sand infiltration of any Well) and the depreciation of personal property due to ordinary wear
and tear with respect to the Assets. 

        (b)   Subject
to the provisions of Section 8.1(e) and  Section 8.2(e) hereof, if, after the date of this Agreement but prior to the Closing Date, any portion of
the Assets is destroyed by fire or
other casualty or is taken in condemnation or under right of eminent domain, and the loss as a result of such individual casualty or taking, taken together with all other casualty losses and takings,
exceeds $5,000,000, the transactions evidenced by this Agreement shall nevertheless be consummated and Purchaser shall elect by written notice to Seller prior to Closing either (i) to cause the
Assets affected by any casualty or taking to be repaired or restored to at least its condition prior to such casualty, at Seller's sole cost, as promptly as reasonably practicable (which work may
extend after the Closing Date), (ii) to have Seller indemnify Purchaser through a document reasonably acceptable to Seller and Purchaser against any costs or expenses that Purchaser reasonably
incurs to repair the Assets subject to any casualty or taking or (iii) to treat such casualty or taking as a Title Defect with respect to the affected Property or Properties under  Section 3.4;
provided, however, that notwithstanding anything herein provided to the contrary, Purchaser cannot require Seller to comply with the
remedy set forth in item (i) of this Section 3.5(b) without Seller's prior written consent. In each case, Seller shall retain all rights
to insurance and other claims against third parties with respect to the casualty or taking except to the extent the parties otherwise agree in writing. 

13

 

        (c)   If,
after the date of this Agreement but prior to the Closing Date, any portion of the Assets is destroyed by fire or other casualty or is taken in condemnation or under
right of eminent domain, and the loss to the Assets as a result of such individual casualty or taking, taken together with all other casualty losses and takings, is $5,000,000 or less, the transaction
evidenced by this Agreement shall nevertheless be consummated and Seller shall, at Closing, pay to Purchaser all sums paid to Seller by third parties by reason of such casualty or taking and shall
assign, transfer and set over to Purchaser all of Seller's right, title and interest (if any) in insurance claims, unpaid awards, and other rights against third parties (other than Affiliates of
Seller and its and their directors, officers, employees and agents) arising out of the casualty or taking. 

 Section 3.6 Limitations on Applicability. 

        Subject
to the following sentence, the right of Purchaser to assert a Title Defect under this Agreement shall terminate as of the Title Claim Date, provided there shall be no termination
of Purchaser's or Seller's rights under Section 3.4 with respect to any bona fide Title Defect properly reported in a Title Defect Notice or bona
fide Title Benefit Claim properly reported in a Title Benefit Notice on or before the Title Claim Date. Thereafter, Purchaser's sole and exclusive rights and remedies with regard to title to the
Assets shall be as set forth in, and arising under, the Conveyance transferring the Assets from Seller to Purchaser. 

 Section 3.7 Government Approvals Respecting Assets. 

        (a)   Federal and State Approvals. Purchaser shall, within thirty (30) days after Closing and at Purchaser's own
expense, file for approval with the applicable Governmental Bodies all assignment documents and other state and federal transfer documents required to effectuate the transfer of the Assets. Purchaser
further agrees, promptly after Closing, to take all other actions reasonably required of it by federal or state agencies having jurisdiction to obtain all requisite regulatory approvals with respect
to this transaction, and to use its commercially reasonable efforts to obtain the approval by such federal or state agencies, as applicable, of Seller's assignment documents requiring federal or state
approval in order for Purchaser to be recognized by the federal or state agencies as the owner of the Assets. Purchaser shall provide Seller with the resignation and designation of operator
instruments, and approved copies of the assignment documents and other state and federal transfer documents, as soon as they are available. 

        (b)   Title Pending Governmental Approvals. Until all of the governmental approvals provided for in  Section 3.7(a) have been obtained, the following shall occur with
respect to the affected portion of the Assets: 

	(i)
	Seller
shall continue to hold record title to the affected Leases and other affected portion of the Assets as nominee for Purchaser;

	(ii)
	Purchaser
shall be responsible for all Seller Assumed Obligations with respect to the affected Leases and other affected portion of the Assets as if Purchaser was the
record owner of such Leases and other portion of the Assets as of the Effective Time; and

	(iii)
	Seller
shall act as Purchaser's nominee but shall be authorized to act only upon and in accordance with Purchaser's instructions, and Seller shall have no authority,
responsibility or discretion to perform any tasks or functions with respect to the affected Leases and other affected portion of the Assets other than those which are purely administrative or
ministerial in nature, unless otherwise specifically requested and authorized by Purchaser in writing. 

14

 

        (c)   Denial of Required Governmental Approvals. If the federal or state agency fails to do so within twenty-four
(24) months after the Closing, Seller may continue to hold record title to the affected Leases and other affected Assets as Purchaser's nominee or, at Seller's option, it may terminate this
Agreement and all its obligations hereunder as to the affected Leases and other affected portion of the Assets by giving sixty (60) days written notice to Purchaser. Upon such termination:
(i) this Agreement shall be null and void and terminated as to the affected Leases and other affected portion of the Assets, (ii) Purchaser shall promptly reassign and return to Seller
the assignment documents and any and all other documents, materials and data previously delivered to Purchaser with respect to the affected Leases and other affected portion of the Assets, and
(iii) Seller shall pay to Purchaser the Allocated Value of the affected Property (without interest), less the proceeds of Hydrocarbon production received by Purchaser (which Purchaser may
retain as its sole property) net of all expenses, overhead, royalties, and costs of operations (including plugging and abandonment expenses but excluding mortgage interest and any burdens, liens, or
encumbrances created by Purchaser which must be released prior to this payment) attributable to the affected Leases or other affected portion of the Assets from the Effective Time forward, plus
interest payable on such net amount at the Agreed Interest Rate from (but not including) the Closing Date to (and including) the date on which such amount is paid to Purchaser. In no event, however,
shall Seller ever be required to reimburse Purchaser for any expenditures associated with workovers, recompletions, sidetracks, or the drilling, completion or plugging and abandonment of wells drilled
or work performed by Seller or any of its Affiliates. 

ARTICLE 4

ENVIRONMENTAL MATTERS  

 Section 4.1 Assessment. 

        From
and after the date of execution of this Agreement until the Closing Date, Seller shall afford to Purchaser and its officers, employees, agents and authorized representatives
reasonable access to the Assets, including the Records in accordance with Section 7.1. During such period, Seller shall also make available to
Purchaser, upon reasonable notice during normal business hours, Seller's personnel knowledgeable with respect to the Assets in order that Purchaser may make such diligent investigation as Purchaser
considers desirable. Upon notice to Seller, Purchaser shall have the right to conduct an environmental assessment of all or any portion of the Properties (the "Assessment"), to be conducted by a
reputable environmental consulting or engineering firm approved in advance in writing by Seller (such approval not to be unreasonably withheld), but only to the extent that Seller may grant such right
without violating any obligations to any third party (provided that Seller shall use its commercially reasonable efforts to obtain any necessary third party consents to any Assessment to be conducted
by Purchaser). The Assessment shall be conducted at the sole cost and expense of Purchaser, and shall be subject to the indemnity provisions of  Section 4.4. Prior to conducting any sampling, boring,
 drilling or other invasive investigative activity with respect to the Properties
("Invasive Activity"), Purchaser shall furnish for Seller's review a proposed scope of such Invasive Activity, including a description of the activities to be conducted and a description of the
approximate locations of such activities. If any of the proposed activities may unreasonably interfere with normal operation of the Properties, Seller may request an appropriate modification of the
proposed Invasive Activity. Seller shall have the right to be present during any Assessment of the Properties and shall have the right, at its option and expense, to split samples with Purchaser.
After completing any Assessment of the Properties, Purchaser shall, at its sole cost and expense, restore the Properties to their condition prior to the commencement of such Assessment, unless Seller
requests otherwise, and shall promptly dispose of all drill cuttings, corings, or other investigative-derived wastes generated in the course of the Assessment. Purchaser shall maintain, and shall
cause its officers, employees, representatives, consultants and advisors to maintain, all 

15

 

information
obtained by Purchaser pursuant to any Assessment or other due diligence activity as strictly confidential until the Closing occurs, unless disclosure of any facts discovered through such
Assessment is required under any Laws. Purchaser shall provide Seller with a copy of the final draft of all environmental reports prepared by, or on behalf of, Purchaser with respect to any Assessment
or Invasive Activity conducted on the Properties. In the event that any necessary disclosures under applicable Laws are required with respect to matters discovered by any Assessment conducted by, for
or on behalf of Purchaser, Purchaser agrees that Seller shall be the responsible party for disclosing such matters to the appropriate Governmental Bodies; provided that, if Seller fails to promptly
make such disclosure and Purchaser or any of its Affiliates is legally obligated to make such disclosure, such Person shall have the right to fully comply with such legal obligation. 

 Section 4.2 NORM, Wastes and Other Substances. 

        Purchaser
acknowledges that the Assets have been used for the exploration, development, and production of Hydrocarbons and that there may be petroleum, produced water, wastes, or other
substances or materials located in, on or under the Properties or associated with the Assets. Equipment and sites included in the Assets may contain Hazardous Materials, including NORM. NORM may affix
or attach itself to the inside of wells, materials, and equipment as scale, or in other forms. The wells, materials, and equipment located on the Properties or included in the Assets may contain
Hazardous Materials, including NORM. Hazardous Materials, including NORM, may have come in contact with various environmental media, including without limitation, water, soils or sediment. Special
procedures may be required for the assessment, remediation, removal, transportation, or disposal of environmental media and Hazardous Materials, including NORM, from the Assets. 

 Section 4.3 Environmental Defects. 

        If,
as a result of its investigation pursuant to Section 4.1, Purchaser determines that with respect to the Assets, there exists a
violation of an Environmental Law (other than with respect to NORM) (in each case, an "Environmental Defect"), then on or prior to March 1, 2007 (the "Environmental Claim Date"), Purchaser may
notify Seller in writing of such Environmental Defect (an "Environmental Defect Notice"). For all purposes of this Agreement, Purchaser shall be deemed to have waived any Environmental Defect which
Purchaser fails to assert as an Environmental Defect by an Environmental Defect Notice received by Seller on or before the Environmental Claim Date. To be effective, each such notice shall set forth
(i) a description of the matter constituting the alleged Environmental Defect, (ii) the Units/Warranty Wells and associated Assets affected by the Environmental Defect, (iii) the
estimated Lowest Cost Response to eliminate the Environmental Defect in question (the "Environmental Defect Amount"), and (iv) supporting documents reasonably necessary for Seller to verify the
existence of the alleged Environmental Defect and the Environmental Defect Amount. Purchaser shall furnish Seller once every two (2) weeks until the Environmental Claim Date with an
Environmental Defect Notice if any officer of Purchaser or its Affiliates discover or become aware of an Environmental Defect during such two (2) week period. Seller shall have the right, but
not the obligation, to cure any Environmental Defect before Closing or, provided that the parties shall have agreed to the general plan of remediation with respect to such Environmental Defect and the
time period by which such remediation shall take place, after Closing. If Seller disagrees with any of Purchaser's assertions with respect to the existence of an Environmental Defect or the
Environmental Defect Amount, Purchaser and Seller will attempt to resolve the dispute prior to Closing. If the dispute cannot be resolved within ten (10) days of the first meeting of Purchaser
and Seller, either party may submit the dispute to an environmental consultant approved in writing by Seller and Purchaser that is experienced in environmental corrective action at oil and gas
properties in the relevant jurisdiction and that shall not have performed professional services for either party or any of their respective Affiliates during the previous five years (the "Independent
Expert"). The Independent Expert may elect to conduct the dispute resolution proceeding by written submissions from Purchaser and Seller with 

16

 

exhibits,
including interrogatories, supplemented with appearances by Purchaser and Seller, if necessary, as the Independent Expert may deem necessary. After the parties and Independent Expert have
had the opportunity to review all such submissions, the Independent Expert shall call for a final, written offer of resolution from each party. The Independent Expert shall render its decision within
twenty (20) Business Days of receiving such offers by selecting one or the other of the offers. The Independent Expert may not award damages, interest or penalties to either party with respect
to any matter. The decision of the Independent Expert shall be final and binding upon both parties, without right of appeal. Seller and Purchaser shall each bear its own legal fees and other costs of
presenting its case to the Independent Expert. Each party shall bear one-half of the costs and expenses of the Independent Expert. The parties shall adjust the Purchase Price to reflect
the Environmental Defect Amounts, as agreed by the parties or as determined by the Independent Expert, for all uncured Environmental Defects; provided, that notwithstanding anything to the contrary,
(a) in no event shall there be any adjustments to the Purchase Price for any individual uncured Environmental Defect for which the Environmental Defect Amount therefor does not exceed $200,000
("Individual Environmental Deductible"); and (b) in no event shall there be any adjustments to the Agreed Asset Value for any uncured Environmental Defect unless the aggregate Environmental
Defect Amount attributable to all such Environmental Defects, taken together with the aggregate Title Defect Amounts
attributable to all uncured Title Defects, exceeds the Aggregate Defect Deductible, after which point Purchaser shall be entitled to adjustments to the Purchase Price or other remedies only with
respect to uncured Title Defects and uncured Environmental Defects where the aggregate Title Defect Amounts and Environmental Defect Amounts attributable thereto are in excess of such Aggregate Defect
Deductible. To the extent the Independent Expert fails to determine any disputed Environmental Defect Amounts prior to Closing, then, within ten (10) days after the Independent Expert delivers
written notice to Purchaser and Seller of his award with respect to an Environmental Defect Amount, Seller shall pay to Purchaser the amount, if any, so awarded by the Independent Examiner, plus
interest payable on such amount at the Agreed Interest Rate from (but not including) the Closing Date to (and including) the date on which such amount is paid to Purchaser. 

 Section 4.4 Inspection Indemnity. 

        PURCHASER HEREBY AGREES TO DEFEND, INDEMNIFY, RELEASE, PROTECT, SAVE AND HOLD HARMLESS THE SELLER INDEMNIFIED PERSONS FROM AND AGAINST ANY AND ALL LOSSES ARISING
OUT OF OR RELATING TO ANY DUE DILIGENCE ACTIVITY CONDUCTED BY PURCHASER OR ITS AGENTS, WHETHER BEFORE OR AFTER THE EXECUTION OF THIS AGREEMENT, REGARDLESS OF FAULT. The
indemnity obligation set forth in this Section 4.4 shall survive the Closing or termination of this Agreement.

commercially reasonable efforts to assist the other with respect to such filings, applications and negotiations. 

        (b)   As
promptly as practicable, and in any event not more than thirty (30) days following the date of this Agreement, Seller and Purchaser will file with the Federal
Trade Commission and the Department of Justice, as applicable, the required notification and report forms and will as promptly as practicable furnish any supplemental information which may be
requested in connection therewith. Seller and Purchaser will request expedited treatment (i.e., early termination) of such filing. Seller and Purchaser shall use commercially reasonable efforts to
make all other filings and submissions on a prompt and timely basis in connection with the filings required by this Section 7.2(b) and cooperate
with each other and use all commercially reasonable efforts to assist the other with respect to such filings, applications and negotiations. All filing fees incurred in connection with the filings
made pursuant to this Section 7.2 shall be borne fifty (50) percent by Seller and fifty (50) percent by Purchaser. 

 Section 7.3 Notification of Breaches. 

        Until
the Closing, 

        (a)   Purchaser
shall notify Seller promptly after Purchaser obtains actual knowledge that any representation or warranty of Seller, as applicable, contained in this Agreement
is untrue in any material respect or will be untrue in any material respect as of the Closing Date, or that any covenant or agreement to be performed or observed by Seller prior to or on the Closing
Date has not been so performed or observed in any material respect. 

        (b)   Seller
shall notify Purchaser promptly after Seller obtains actual knowledge that any representation or warranty of Purchaser contained in this Agreement is untrue in
any material respect or will be untrue in any material respect as of the Closing Date, or that any covenant or agreement to be performed or observed by Purchaser prior to or on the Closing Date has
not been so performed or observed in any material respect. 

        (c)   If
any of Purchaser's or Seller's representations or warranties is untrue or shall become untrue in any material respect between the date of execution of this Agreement
and the Closing Date, or if any of Purchaser's or Seller's covenants or agreements to be performed or observed prior to or on the Closing Date shall not have been so performed or observed in any
material respect, but if such breach of representation, warranty, covenant or agreement shall (if curable) be cured by the Closing, then such breach shall be considered not to have occurred for all
purposes of this Agreement. No such notification shall affect the representations or warranties of the parties or the conditions to their respective obligations hereunder. 

        (d)   There
shall be no breach of the covenants in this Section as a result of a party's failure to report a breach of any representation or warranty or a failure to perform
or observe any covenant or agreement of which it had knowledge if the party subject to the breach or failure also had knowledge thereof prior to Closing. 

27

 

 Section 7.4 Letters-in-Lieu; Assignments; Operatorship. 

        (a)   Seller
will execute on the Closing Date letters in lieu of division and transfer orders relating to the Assets, on forms prepared by Seller and reasonably satisfactory
to Purchaser, to reflect the transaction contemplated hereby. 

        (b)   Seller
will prepare and execute, and Purchaser will execute, on the Closing Date, all assignments necessary to convey to Purchaser all federal and state Leases in the
form as prescribed by the applicable Governmental Body and otherwise acceptable to Purchaser and Seller. 

        (c)   Seller
makes no representations or warranties to Purchaser as to transferability or assignability of operatorship of any Seller Operated Assets. Rights and obligations
associated with operatorship of such Properties are governed by operating and similar agreements covering the Properties and will be determined in accordance with the terms of such agreements.
However, Seller will assist Purchaser in Purchaser's efforts to succeed Seller as operator of any Wells and Units included in the Assets. Purchaser shall, promptly following Closing, file all
appropriate forms and declarations or bonds with federal and state agencies relative to its assumption of operatorship. For all Seller Operated Assets, Seller shall execute and deliver to Purchaser,
and Purchaser shall promptly file the appropriate forms (including a change of operator card on the form established by the Department of Conservation, duly executed by Seller and naming Purchaser as
the successor operator) with the applicable regulatory agency transferring operatorship of such Assets to Purchaser. 

 Section 7.5 Public Announcements. 

        Until
the Closing, neither Seller nor Purchaser shall make any press release or other public announcement regarding the existence of this Agreement, the contents hereof or the
transactions contemplated hereby without the prior written consent of the others; provided, however, the foregoing shall not restrict disclosures by Purchaser or Seller which are required by
applicable securities or other laws or regulations or the applicable rules of any stock exchange having jurisdiction over the disclosing party or its Affiliates; and provided, further, that, Purchaser
may disclose the existence and contents of this Agreement, the transactions contemplated hereby and information regarding the Assets to the Standard & Poor's and Moody's rating agencies and any
actual or potential lenders or other financing sources of Purchaser. At or after Closing, the content of any press release or public announcement first announcing the consummation of this transaction
shall be subject to the prior review and reasonable approval of Seller and Purchaser; provided, however, the foregoing shall not restrict disclosures by Purchaser or Seller which are required by
applicable securities or other laws or regulations or the applicable rules of any stock exchange having jurisdiction over the disclosing party or its Affiliates. 

 Section 7.6 Operation of Business. 

        Except
as set forth on Schedule 7.6, until the Closing, Seller (i) will operate the Assets and the business thereof in the
ordinary course, (ii) will not, without the prior written consent of Purchaser, which consent shall not be unreasonably withheld, commit to any operation, or series of related operations
thereon, reasonably anticipated to require future capital expenditures by Purchaser as owner of the Assets in excess of $150,000, or make any capital expenditures in respect of the Assets in excess of
$150,000, or terminate, materially amend, execute or extend any material Contracts affecting the Assets, (iii) will maintain insurance coverage on the Assets presently furnished by
nonaffiliated third parties in the amounts and of the types presently in force, (iv) will use commercially reasonable efforts to maintain in full force and effect all Leases, (v) will
maintain all material governmental permits and approvals affecting the Assets, (vi) will not transfer, farmout, sell, hypothecate, encumber or otherwise dispose of any Assets, except for
(A) sales and dispositions of Hydrocarbon production in the ordinary 

28

 

course
of business consistent with past practices or (B) transfers, farmouts, hypothecations, encumbrances or other dispositions of Assets, in one or more transactions, not exceeding $500,000
of consideration (in any form), in the aggregate, (vii) will not enter into any settlement or agreement with respect to Taxes, or make or change any election with respect to Taxes, relating to
the Assets and (viii) will not commit to do any of the foregoing. Purchaser's approval of any action restricted by this Section 7.6 shall
be considered granted within ten (10) days (unless a shorter time is reasonably required by the circumstances and such shorter time is specified in Seller's written notice) of Seller's written
notice to Purchaser requesting such consent unless Purchaser notifies Seller to the contrary in writing during that period. In the event of an emergency, Seller may take such action as a prudent
operator would take and shall notify Purchaser of such action promptly thereafter. 

        Purchaser
acknowledges that Seller may own an undivided interest in certain of the Assets, and Purchaser agrees that the acts or omissions of the other working interest owners who are
not affiliated with Seller shall not constitute a violation of the provisions of this Section 7.6 nor shall any action required by a vote of
working interest owners constitute such a violation so long as Seller has voted its interest in a manner consistent with the provisions of this  Section 7.6. 

 Section 7.7 Preference Rights and Transfer Requirements. 

        (a)   The
transactions contemplated by this Agreement are expressly subject to all validly existing and applicable Preference Rights and Transfer Requirements. Prior to the
Closing Date, Seller shall initiate all procedures which are reasonably required to comply with or obtain the waiver of all Preference Rights and Transfer Requirements set forth in  Schedule 5.13
with respect to the transactions contemplated by this Agreement. Seller shall use its commercially reasonable efforts to obtain all
applicable consents and to obtain waivers of applicable Preference Rights; provided, however, Seller shall not be obligated to pay any consideration to (or incur any cost or expense for the benefit
of) the holder of any Preference Right or Transfer Requirement in order to obtain the waiver thereof or compliance therewith. 

        (b)   If
the holder of a Preference Right elects prior to Closing to purchase the Asset subject to a Preference Right (a "Preference Property") in accordance with the terms of
such Preference Right, and Seller receives written notice of such election prior to the Closing, such Preference Property will be eliminated from the Assets and the Purchase Price shall be reduced by
the Allocated Value of the Preference Property. 

        (c)   If

	(i)
	a
third party brings any suit, action or other proceeding prior to the Closing seeking to restrain, enjoin or otherwise prohibit the consummation of the transactions
contemplated hereby in connection with a claim to enforce a Preference Right;

	(ii)
	an
Asset is subject to a Transfer Requirement that provides that transfer of such Asset without compliance with such Transfer Requirement will result in termination or
other material impairment of any rights in relation to such Asset, and such Transfer Requirement is not waived, complied with or otherwise satisfied prior to the Closing Date; or

	(iii)
	the
holder of a Preference Right does not elect to purchase such Preference Property or waive such Preference Right with respect to the transactions contemplated by
this Agreement prior to the Closing Date and the time in which the Preference Right may be exercised has not expired, 

29

 

then,
unless otherwise agreed by Seller and Purchaser, the Asset or portion thereof affected by such Preference Right or Transfer Requirement (a "Retained Asset") shall be held back from the Assets to
be transferred and conveyed to Purchaser at Closing and the Purchase Price to be paid at Closing shall be reduced by the Allocated Value of such Retained Asset pursuant to  Section 7.7(b). Any
Retained Asset so held back at the initial Closing will be conveyed to Purchaser at a delayed Closing (which shall become the
new Closing Date with respect to such Retained Asset), within ten (10) days following the date on which the suit, action or other proceeding, if any, referenced in clause (i) above is
settled or a judgment is rendered (and no longer subject to appeal) permitting transfer of the Retained Asset to Purchaser pursuant to this Agreement and Seller obtains, complies with, obtains a
waiver of or notice of election not to exercise or otherwise satisfies all remaining Preference Rights and Transfer Requirements with respect to such Retained Asset as contemplated by this Section (or
if multiple Assets are Retained Assets, on a date mutually agreed to by the parties in order to consolidate, to the extent reasonably possible, the number of Closings). At the delayed Closing,
Purchaser shall pay Seller a purchase price equal to the amount by which the Purchase Price was reduced on account of the holding back of such Retained Asset (as adjusted pursuant to  Section 2.2
through the new Closing Date therefor); provided, however, if all such Preference Rights and Transfer Requirements with respect to
any Retained Asset so held back at the initial Closing are not obtained, complied with, waived or otherwise satisfied as contemplated by this Section within one hundred eighty (180) days after
the initial Closing has occurred with respect to any Asset, then such Retained Asset shall be eliminated from the Assets and shall become an Excluded Asset and this Agreement, unless Seller and
Purchaser agree to proceed with a closing on such Retained Asset, in which case Purchaser and Purchaser shall be deemed to have waived any objection (and shall be obligated to indemnify the Seller
Indemnified Persons for all Losses) with respect to non-compliance with such Preference Rights and Transfer Requirements with respect to such Retained Asset(s). 

        (d)   Purchaser
acknowledges that Seller desires to sell all of the Assets to Purchaser and would not have entered into this Agreement but for Purchaser's agreement to
purchase all of the Assets as herein provided. Accordingly, it is expressly understood and agreed that Seller does not desire to sell any Property affected by a Preference Right to Purchaser unless
the sale of all of the Assets is consummated by the Closing Date in accordance with the terms of this Agreement. In furtherance of the foregoing, Seller's obligation hereunder to sell the Preference
Properties to Purchaser is expressly conditioned upon the consummation by the Closing Date of the sale of all of the Assets (other than Retained Assets or other Assets excluded pursuant to the express
provisions of this Agreement) in accordance with the terms of this Agreement, either by conveyance to Purchaser or conveyance pursuant to an applicable Preference Right; provided that, nothing herein
is intended or shall operate to extend or apply any Preference Right to any portion of the Assets which is not otherwise burdened thereby. Time is of the essence with respect to the parties' agreement
to consummate the sale of the Assets by the Closing Date (or by the delayed Closing Date pursuant to Section 7.7(c)). 

30

 

 Section 7.8 Tax Matters. 

        (a)   Subject
to the provisions of Section 12.3, Seller shall be responsible for all Taxes related to the Assets (other
than ad valorem, property, severance, Hydrocarbon production and similar Taxes based upon or measured by the ownership or operation of the Assets or the production of Hydrocarbons therefrom, which are
addressed in Section 1.4) attributable to any period of time at or prior to the Closing Date, and Purchaser shall be responsible for all such
Taxes related to the Assets attributable to any period of time after the Closing Date. Notwithstanding the foregoing, Seller shall handle payment to the appropriate Governmental Body of all Taxes with
respect to the Assets which are required to be paid prior to Closing (and shall file all Tax Returns with respect to such Taxes). If requested by Purchaser, Seller will assist Purchaser with
preparation of all ad valorem and property Tax Returns for periods ending on or before December 31, 2006 (including any extensions requested). Seller shall deliver to Purchaser within thirty
(30) days of filing copies of all Tax Returns to be filed by Seller relating to the Assets and any supporting documentation to be provided by Seller to Governmental Bodies for Purchaser's
approval, which shall not be unreasonably withheld, excluding Tax Returns related to income tax, franchise tax, or other similar Taxes. Purchaser shall file all Tax Returns covering Taxes treated as
Property Costs that are required to be filed after the Closing Date unless covered above. With respect to such Tax Returns covering a taxable period which includes the Effective Date, Purchaser shall
provide a copy of such Tax Return to Seller within 30 days of filing for Seller's approval, which shall not be unreasonably withheld. 

        (b)   Purchaser
and Seller shall cooperate fully, as and to the extent reasonably requested by the other party, in connection with the filing of any Tax Returns and any audit,
litigation or other Proceeding with respect to Taxes. Such cooperation shall include the retention and (upon the other party's request) the provision of records and information which are reasonably
relevant to any such audit, litigation or other Proceeding and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided
hereunder. Each of Purchaser and Seller agrees (i) to retain all books and records with respect to Tax matters pertinent to the acquired assets relating to any taxable period beginning before
the Closing Date until the expiration of the statute of limitations (and, to the extent notified by Purchaser or Seller, any extensions thereof) of the respective taxable periods, and to abide by all
record retention agreements entered into with any Governmental Body, and (ii) to give the other party reasonable written notice prior to transferring, destroying or discarding any such books
and records and, if the other party so requests, each party shall allow the other party the option of taking possession of such books and records prior to their disposal. Purchaser and Seller further
agree, upon request, to use their commercially reasonable efforts to obtain any certificate or other document from any Governmental Body or any other Person as may be necessary to mitigate, reduce or
eliminate any Tax that could be imposed with respect to the transactions contemplated. 

        (c)   Purchaser
and Seller shall cooperate fully, as and to the extent reasonably requested by the other party, in connection of accommodating a 1031 exchange (as provided for
under IRC Section 1031 of the Code). Purchaser or Seller reserves the right, at or prior to Closing, to assign its rights under this Agreement with respect to all or a portion of the Purchase
Price, and that portion of the Assets associated therewith ("1031 Assets"), to a Qualified Intermediary ("QI") (as that term is defined in Section 1.1031(k)-1(g)(4)(v) of the
Treasury Regulations) to accomplish this transaction, in whole or in part, in a manner that will comply with the requirements of a like-kind exchange ("Like-Kind Exchange")
pursuant to Section 1031 of the Code. If Purchaser so elects, Purchaser may assign its rights under this Agreement to the 1031 Assets to the QI. Seller hereby (i) consents to Purchaser's
assignment of its rights in this Agreement with respect to the 1031 Assets, and (ii) if such an 

31

 

assignment
is made, agrees to transfer all or a portion of the Assets into the qualified trust account at Closing as directed in writing by Purchaser. Purchaser acknowledges and agrees that a whole or
partial assignment of this Agreement to a QI shall not release Purchaser from any of its respective liabilities and obligations to Seller or expand any liabilities or obligations of Seller under this
Agreement. Neither party represents to the other that any particular tax treatment will be given to either party as a result of the Like-Kind Exchange. Seller shall not be obligated to pay
any additional costs or incur any additional obligations in its sale of the Assets if such costs are the result of Purchaser's Like-Kind Exchange, and Purchaser shall hold harmless and
indemnify Seller from and against all claims, losses and liabilities (including reasonable attorneys' fees, court costs and related expenses), if any, resulting from such a Like-Kind
Exchange. 

 Section 7.9 Further Assurances. 

        Except
to the extent otherwise expressly provided herein, it is the intent of the parties that Seller convey to Purchaser substantially all of its right, title and interest in and to all
oil, gas and mineral leases and related assets owned by them in the geographic area depicted on Schedule 7.9. After Closing, Seller and Purchaser
each agrees to take such further actions and to execute, acknowledge and deliver all such further documents as are reasonably requested by the other party for carrying out the purposes of this
Agreement or of any document delivered pursuant to this Agreement. 

 Section 7.10 Guaranty Agreement. 

        On
even date herewith, Purchaser shall deliver to Seller the Guaranty Agreement duly executed by EXCO Resources, Inc. 

 Section 7.11 Insurance; Financial Information. 

        (a)   Effective
as of the Closing Date, Purchaser shall cause the following insurance to be carried and maintained with respect to the Assets: (i) general liability
insurance with combined single limits per occurrence of not less than $1,000,000.00 for bodily injury and property damage, including property damage by blowout and cratering, completed operations, and
contractual liability as respects any contract into which Purchaser may enter under the terms of this Agreement; and (ii) operators extra expense insurance with limits of not less than
$1,000,000.00 per occurrence, covering the costs of controlling a blowout, and certain other related and/or resulting costs and seepage and pollution liability. 

        (b)   Between
the date of this Agreement and the Closing Date, Seller shall deliver to the Chief Operating Officer of EXCO Resources, Inc. copies of all production
reports and daily drilling reports relating to Seller's operation of the Assets promptly after the preparation thereof in the ordinary course of business. 

32

  

 Section 7.12 No Solicitation of Transactions. 

        So
long as Purchaser is not in default of this Agreement or, if Purchaser is in default hereunder, Purchaser cures such default within ten (10) days after receiving written notice
thereof from Seller, Seller shall not, directly or indirectly, through any officer, director, stockholder, employee, agent, financial advisor, banker or other representative or Affiliate, or
otherwise, solicit, initiate, or encourage the submission of any proposal or offer from any Person relating to any acquisition or purchase of all or any material portion of the Assets or participate
in any negotiations regarding, or furnish to any other Person any information with respect to, or otherwise cooperate in any way with, or assist or participate in, facilitate, or encourage, any effort
or attempt by any other Person to do or seek any of the foregoing. Seller shall communicate as soon as reasonably practicable to Purchaser the material terms of any such proposal (and the identity of
the party making such proposal) which it may receive and, if such proposal is in writing, Seller shall promptly deliver a copy of such proposal to Purchaser. Seller agrees not to release any third
party from, or waive any provision of, any confidentiality agreement relating to the Assets to which Seller or any of its Affiliates is a party. Seller immediately shall cease and cause to be
terminated all existing discussions or negotiations with any parties conducted heretofore with respect to any of the foregoing. 

 Section 7.13 Transition Services Agreement.  

        Between the date hereof and the Closing Date, each of Seller and Purchaser shall use its reasonable efforts to negotiate in good faith a form of transition
services agreement on terms that are mutually acceptable to Seller and Purchaser to be executed at Closing by Seller and Purchaser (the "Transition Services Agreement"). 

 Section 7.14 Employees. 

        As
promptly as reasonably practical following the execution of this Agreement, the parties will use reasonable efforts to work together concerning employees. 

 Section 7.15 Hedges. 

        (a)   Seller
has entered into the hedging transactions set forth on Schedule 7.15 (the "Hedging Transactions") with the
counterparties specified therein (the "Counterparties"). Purchaser covenants and agrees that each of the Counterparties has agreed and will (i) allow the assignment by Seller to Purchaser at
the Closing of all of the trades that are the subject of the Hedging Transactions and (ii) release Seller from any and all obligations and liabilities related or attributable to such Hedging
Transactions upon such assignment. The respective agreements between Seller and each Counterparty shall be evidenced by a Novation Agreement that is in form and substance reasonably acceptable to
Seller. 

        (b)   At
the Closing, Purchaser shall accept an assignment from Seller of all of the trades that are the subject of the Hedging Transactions and shall assume all obligations
and liabilities attributable thereto pursuant to documentation required by the Counterparties. 

33

 

        (c)   Within
five (5) Business Days of the termination by Purchaser or Seller, as the case may be, of this Agreement in accordance with Section 10.1, Seller
shall furnish to Purchaser written notice of whether it elects to unwind the Hedging Transactions. If Seller notifies Purchaser that it does not elect to unwind the Hedging Transactions, Purchaser
shall have no further obligations whatsoever to Seller with respect to the Hedging Transactions. However, if Seller notifies Purchaser that it elects to unwind the Hedging Transactions, Purchaser
shall be obligated for and shall promptly pay, and Purchaser does hereby agree to indemnify and hold harmless Seller from and against, any and all Losses suffered by Seller resulting from or
attributable to the Hedging Transactions and the unwind thereof unless the termination of this Agreement resulted from the default by Seller of its obligations under this Agreement, in which case
Purchaser shall not be liable for such Losses. 

 Section 7.16 Contract Review.  

        If, after reviewing the Material Contracts not cancelable upon thirty (30) days notice, Purchaser reasonably and in good faith determines that such
Material Contracts (other than the Contracts set forth on Schedules 1.2(d) and 1.2(e)) will result in an
adverse economic effect on the value of the Assets as a result of above-market terms that were not considered by Purchaser in determining the Purchase Price because information with respect thereto
was not made available to Purchaser by Seller prior to the date hereof and provides written notice thereof to Seller not later than January 12, 2007, then the Purchase Price shall be reduced by
the amount by which such adverse economic effect exceeds $5,000,000. Purchaser shall provide Seller with documentation reasonably substantiating Purchaser's determination of such reduction to the
Purchase Price. 

 Section 7.17 Contract Delivery.  

        On or before January 5, 2007, Seller shall use reasonable efforts to furnish or make available to Purchaser copies of each Material Contract and all
amendments thereto, which, to Seller's knowledge, exist. 

 Section 7.18 Cure of Misrepresentations.  

        If any of the representations and warranties contained in Article 5 hereof are determined (whether by
notice from Purchaser or otherwise) to have been untrue or incorrect as of the date of this Agreement, then any cure by Seller of same shall be at its own expense.

 Section 9.4 Closing Adjustments.  

        (a)   Not
later than three (3) Business Days prior to the Closing Date, Seller shall prepare and deliver to Purchaser, based upon the best information available to
Seller, a preliminary settlement statement estimating the Adjusted Purchase Price after giving effect to all adjustments listed in Section 2.2.
The estimate delivered in accordance with this Section 9.4(a) shall constitute the dollar amount to be paid by Purchaser to Seller at the Closing
(the "Closing Payment"). Until one (1) Business Day before the Closing Date, Purchaser shall have the opportunity to review and discuss the preliminary settlement statement with Seller;
provided, however, Seller shall not be required to make any change thereto to which Seller does not agree. 

37

 

        (b)   As
soon as reasonably practicable after the Closing but not later than ninety (90) days following the Closing Date, Seller shall prepare and deliver to Purchaser
a statement setting forth the final calculation of the Agreed Purchase Price and showing the calculation of each adjustment, based, to the extent possible, on actual credits, charges, receipts and
other items before and after the Effective Time and taking into account all adjustments provided for in this Agreement (the "Final Purchase Price"). Seller shall, at Purchaser's request, supply
reasonable documentation available to support any credit, charge, receipt or other item. Seller shall afford Purchaser and its representatives the opportunity to review such statement and the
supporting schedules, analyses, workpapers, and other underlying records or documentation as are reasonably necessary and appropriate in Purchaser's review of such statement. Each party shall
cooperate fully and promptly with the other and their respective representatives in such examination with respect to all reasonable requests related thereto. As soon as reasonably practicable but not
later than the 30th day following receipt of Seller's statement hereunder, Purchaser shall deliver to Seller a written report containing any changes that Purchaser proposes be made to such statement.
Seller and Purchaser shall undertake to agree on the final statement of the Final Purchase Price no later than one hundred eighty (180) days after the Closing Date (the "Final Settlement
Date"). In the event that Seller and Purchaser cannot reach agreement by the Final Settlement Date, either party may refer the remaining matters in dispute to Ernst & Young LLP, or such other
nationally-recognized independent accounting firm as may be mutually accepted by Purchaser and Seller, for review and final determination (the "Agreed Accounting Firm"). If issues are submitted to the
Agreed Accounting Firm for resolution, Seller and Purchaser shall each enter into a customary engagement letter with the Agreed Accounting Firm at the time the issues remaining in dispute are
submitted to the Agreed Accounting Firm. The Agreed Accounting Firm will be directed to (i) review the statement setting forth Seller's calculation of the Final Purchase Price and the records
relating thereto only with respect to items identified by Purchaser in its written report containing changes to such statement that remain disputed immediately following the Final Settlement Date and
(ii) determine the final adjustments. Each party shall furnish the Agreed Accounting Firm such work papers and other records and information relating to the objections in dispute as the Agreed
Accounting Firm may reasonably request and that are available to such party or its Affiliates (and such parties' independent public accountants). The parties will, and will cause their representatives
to, cooperate and assist in the conduct of any review by the Agreed Accounting Firm, including, but not limited to, making available books, records and, as available, personnel as reasonably required.
The Agreed Accounting Firm shall conduct the arbitration proceedings in Houston, Texas in accordance with the Commercial Arbitration Rules of the American Arbitration Association, to the extent such
rules do not conflict with the terms of this Section 9.4. The Agreed Accounting Firm's determination shall be made within thirty (30) days
after submission of the matters in dispute and shall be final and binding on both parties, without right of appeal and such decision shall constitute an arbitral award upon which a judgment may be
entered by a court having jurisdiction thereof. In determining the proper amount of any adjustment to the Final Purchase Price, the Agreed Accounting Firm shall not increase the Final Purchase Price
more than the increase proposed by Seller nor decrease the Final Asset Value more than the decrease proposed by Purchaser, as applicable, and may not award damages or penalties to either party with
respect to any matter. Seller and Purchaser shall each bear its own legal fees and other costs of presenting its case. Each party shall bear one-half of the costs and expenses of the
accounting firm. Within ten (10) Business Days after the date on which the parties or the Agreed Accounting Firm, as applicable, finally determines the disputed matters, (x) Purchaser
shall pay to Seller the amount by which the Final Purchase Price exceeds the Closing Payment or (y) Seller shall pay to Purchaser the amount by which the Closing Payment exceeds the Final
Purchase Price, as applicable. Any post-Closing payment pursuant to this Section 9.4(b) shall bear interest at the Agreed Interest
Rate from (but not including) the Closing Date to (and including) the date both Purchaser and Seller have executed the final settlement statement. 

38

 

        (c)   All
payments made or to be made hereunder to Seller shall be by electronic transfer of immediately available funds to the account of Anadarko Petroleum Corporation,
Account No. 5762707 at JPMorgan Chase, Chicago, IL, ABA No. 021000021, for the credit of Seller or to such other bank and account as may be specified by Seller in writing. All payments
made or to be made hereunder to Purchaser shall be by electronic transfer of immediately available funds to a bank and account specified by Purchaser in writing to Seller.

TERMINATION  

 Section 10.1 Termination. 

        This
Agreement may be terminated and the transactions contemplated hereby abandoned at any time prior to the Closing: 

        (a)   by
mutual written consent of Seller and Purchaser; 

        (b)   by
either Seller or Purchaser, if: 

	(i)
	the
Closing shall not have occurred on or before April 30, 2007 (the "Termination Date"); provided, however, that the right to terminate this Agreement under this  Section 10.1(b)(i) shall not be
available (A) to Seller, if any breach of this Agreement by Seller has been the principal cause of, or
resulted in, the failure of the Closing to occur on or before the Termination Date or (B) to Purchaser, if any breach of this Agreement by Purchaser has been the principal cause of, or resulted
in, the failure of the Closing to occur on or before the Termination Date; or

	(ii)
	there
shall be any Law that makes consummation of the transactions contemplated hereby illegal or otherwise prohibited or a Governmental Body shall have issued an
order, decree, or ruling or taken any other action permanently restraining, enjoining, or otherwise prohibiting the consummation of the transactions contemplated hereby, and such order, decree,
ruling, or other action shall have become final and non appealable; 

        (c)   by
Seller, if (i) any of the representations and warranties of Purchaser contained in this Agreement shall not be true and correct in all material respects
(provided that any such representation or warranty that is already qualified by a materiality standard or a material adverse effect qualification shall not be further qualified); or
(ii) Purchaser shall have failed to fulfill in any material respect any of its obligations under this Agreement; and, in the case of each of clauses (i) and (ii), such misrepresentation,
or breach of warranty, if curable, has not been cured within ten (10) days after written notice thereof from Seller to Purchaser; provided that any cure period shall not extend beyond the
Termination Date and shall not extend the Termination Date; or 

        (d)   by
Purchaser, if (i) any of the representations and warranties of Seller contained in this Agreement shall not be true and correct in all material respects
(provided that any such representation or warranty that is already qualified by a materiality or Material Adverse Effect qualification shall not be further qualified); or (ii) Seller shall have
failed to fulfill in any material respect any of its obligations under this Agreement, and, in the case of each of clauses (i) and (ii), such misrepresentation, breach of warranty or failure,
if curable, has not been cured within ten (10) days after written notice thereof from Purchaser to Seller; provided that any cure period shall not extend beyond the Termination Date and shall
not extend the Termination Date. 

39

 

 Section 10.2 Effect of Termination. 

        If
this Agreement is terminated pursuant to Section 10.1, this Agreement shall become void and of no further force or effect
(except for the provisions of Section 4.4, Section 5.6, Section 6.5,  Section 7.5,
Section 7.15,  Section 11.10, Section 11.11 and  Section 11.12 of this Agreement and this Article 10, the Section entitled "Definitions,"
and Article 12 (other than Section 12.6), all of which shall continue in full force and
effect). Notwithstanding the foregoing, nothing contained in this Section 10.2 shall relieve any party from liability for Losses resulting from
its breach of this Agreement. 

 Section 10.3 Distribution of Deposit Upon Termination. 

        (a)   If
Seller terminates this Agreement (i) because Purchaser has failed to comply with any provision of Sections
8.1(a), 8.1(b) or 8.1(d); or (ii) as the result of any default or breach
by Purchaser of Purchaser's obligations hereunder, then Seller may retain, as its sole and exclusive remedy, the Deposit as liquidated damages, free of any claims by Purchaser or any other Person with
respect thereto. It is expressly stipulated by the parties that the actual amount of damages resulting from such a termination would be difficult if not impossible to determine accurately because of
the unique nature of this Agreement, the unique nature of the Assets, the uncertainties of applicable commodity markets and differences of opinion with respect to such matters, and that the liquidated
damages provided for herein are a reasonable estimate by the parties of such damages. 

        (b)   If
this Agreement is terminated for any reason other than the reasons set forth in Section 10.3(a), then Seller
shall deliver the Deposit to Purchaser without interest thereon, free of any claims by Seller or any other Person with respect thereto after Purchaser has satisfied its obligations under  Section 7.15. 

        (c)   Notwithstanding
anything to the contrary in this Agreement, Purchaser shall not be entitled to receive interest on the Deposit, whether the Deposit is applied against
the Purchase Price or returned to Purchaser pursuant to this Section 10.3. 

ARTICLE 11

        Subject
to the indemnification by Seller under Section 11.5, on the Closing Date, Purchaser shall assume and hereby agrees to

 Section 11.4 Survival. 

        (a)   All
representations and warranties of Seller and Purchaser contained herein shall survive the Closing Date and shall terminate on the first anniversary of the Closing
Date; provided, however, that the representations and warranties contained in Section 5.3, Section 5.4,
Section 5.6, Section 5.8, Section 6.2, Section 6.3, and Section 6.5 (collectively, the
"Fundamental Representations") shall survive until the expiration of the applicable statute of limitations period. Upon the termination of a representation or warranty in accordance with the

        (b)   No

any representation, warranty, covenant or agreement unless it shall have received from the party seeking indemnification a written notice (a "Claim Notice") of the existence of the claim for or in
respect of which indemnification in respect of such representation, warranty, covenant or agreement is being sought on or before the expiration of the applicable survival period set forth in  Section 11.4(a))
. If an Indemnified Party delivers a Claim Notice to an Indemnifying Party before the expiration of the applicable survival
period set forth in Section 11.4(a), then the applicable representation, warranty, covenant or agreement shall survive until, but only for
purposes of, the resolution of the matter covered by such Claim Notice. A Claim Notice shall set forth with reasonable specificity (1) the basis for such claim under this Agreement, and the
facts that otherwise form the basis of such claim and (2) to the extent reasonably estimable, an estimate of the amount of such claim (which estimate shall not be conclusive of the final amount
of such claim) and an explanation of the calculation of such estimate. 

 Section 11.5 Indemnification by Seller. 

        From
and after the Closing, subject to the terms and conditions of this Article 11, Seller shall jointly and severally indemnify,
defend and hold harmless Purchaser and its directors, officers, employees, stockholders, members, agents, consultants, advisors and other representatives (including legal counsel, accountants and
financial advisors) and Affiliates and the successors and permitted assigns of this Agreement of Purchaser (collectively, the "Purchaser Indemnified Persons") from and against any and all Losses
asserted against, resulting from, imposed upon, or incurred or suffered by any Purchaser Indemnified Person to the extent resulting from, arising out of or relating to: 

        (a)   any
breach of any representation or warranty of Seller contained in this Agreement or in any certificate furnished by or on behalf of Seller in connection with this
Agreement; 

        (b)   any

harmless Seller and its directors, officers, employees, agents, consultants, stockholders, advisors and other representatives (including legal counsel, accountants and financial advisors), and
Seller's successors, permitted assigns of this Agreement and Affiliates (collectively, the "Seller Indemnified Persons") from and against any and all Losses, asserted against, resulting from, imposed
upon, or incurred or suffered by any Seller Indemnified Person, directly or indirectly, to the extent resulting from, arising out of, or relating to: 

        (a)   any
breach of any representation or warranty of Purchaser contained in this Agreement or in any certificate furnished by or on behalf of Purchaser to Seller in
connection with this Agreement REGARDLESS OF FAULT; 

        (b)   any
breach or nonfulfillment of or failure to perform any covenant or agreement of Purchaser contained in this Agreement REGARDLESS OF

 Section 11.7 Indemnification Proceedings. 

        (a)   In
the event that any claim or demand for which Seller or Purchaser (such Person, an "Indemnifying Party") may be liable to an Purchaser Indemnified Person under  Section 11.5 or to an Seller
Indemnified Person under Section 11.6 (an "Indemnified
Party") is asserted against or sought to be collected from an Indemnified Party by a third party (a "Third Party Claim,") the Indemnified Party shall with reasonable promptness notify the Indemnifying
Party of such Third Party Claim by delivery of a Claim Notice, provided that the failure or delay to so notify the Indemnifying Party shall not relieve the Indemnifying Party of its obligations under
this Article 11, except (and solely) to the extent that the Indemnifying Party demonstrates that its defense of such Third Party Claim is
actually and materially prejudiced thereby. The Indemnifying Party shall have thirty (30) days from receipt of the Claim Notice from the Indemnified Party (in this  Section 11.7, the "Notice
Period") to notify the Indemnified Party whether or not the Indemnifying Party desires, at the Indemnifying Party's
sole cost and expense, to defend the Indemnified Party against such claim or demand; provided, that the Indemnified Party is hereby authorized prior to and during the Notice Period, and at the cost
and expense of the Indemnifying Party, to file any motion, answer or other pleading that it shall reasonably deem necessary to protect its interests or those of the Indemnifying Party. The
Indemnifying Party shall have the right to assume the defense of such Third Party Claim only if and for so long as the Indemnifying Party (i) notifies the Indemnified Party during the Notice
Period that the Indemnifying Party is assuming the defense of such Third Party Claim, (ii) uses counsel of its own choosing that is reasonably satisfactory to the Indemnified Party, and
(iii) conducts the defense of such Third Party Claim in an active and diligent manner. If the Indemnifying Party is entitled to, and does, assume the defense of any such Third Party Claim, the
Indemnified Party shall have the right to employ separate counsel at its own expense and to participate in the defense thereof; provided, however, that notwithstanding the foregoing, the Indemnifying
Party shall pay the reasonable attorneys' fees of the Indemnified Party if the Indemnified Party's counsel shall have advised the Indemnified Party that there is a conflict of interest that could make
it inappropriate under applicable standards of professional conduct to have 

43

 

common
counsel for the Indemnifying Party and the Indemnified Party (provided that the Indemnifying Party shall not be responsible for paying for more than one separate firm of attorneys and one local
counsel to represent all of the Indemnified Parties subject to such Third Party Claim). If the Indemnifying Party elects (and is entitled) to assume the defense of such Third Party Claim,
(i) no compromise or settlement thereof or consent to any admission or the entry of any judgment with respect to such Third Party Claim may be effected by the Indemnifying Party without the
Indemnified Party's written consent (which shall not be unreasonably withheld, conditioned or delayed) unless the sole relief provided is monetary damages that are paid in full by the Indemnifying
Party (and no injunctive or other equitable relief is imposed upon the Indemnified Party) and there is an unconditional provision whereby each plaintiff or claimant in such Third Party Claim releases
the Indemnified Party from all liability with respect thereto and (ii) the Indemnified Party shall have no liability with respect to any compromise or settlement thereof effected without its
written consent (which shall not be unreasonably withheld). If the Indemnifying Party elects not to assume the defense of such Third Party Claim (or fails to give notice to the Indemnified Party
during the Notice Period or otherwise is not entitled to assume such defense), the Indemnified Party shall be entitled to assume the defense of such Third Party Claim with counsel of its own choice,
at the expense and for the account of the Indemnifying Party; provided, however, that the Indemnified Party shall make no settlement, compromise, admission, or acknowledgment that would give rise to
liability on the part of any Indemnifying Party without the prior written consent of such Indemnifying Party, which consent shall not be unreasonably withheld, conditioned or delayed. 

        (b)   Notwithstanding
the foregoing, the Indemnifying Party shall not be entitled to control (but shall be entitled to participate at its own expense in the defense of), and
the Indemnified Party, shall be entitled to have sole control over, the defense or settlement, compromise, admission, or acknowledgment of any Third Party Claim (i) at the reasonable expense of
the Indemnifying Party, as to which the Indemnifying Party fails to assume the defense during the Notice Period after the Indemnified Party gives notice thereof to the Indemnifying Party or
(ii) at the reasonable expense of the Indemnifying Party, to the extent the Third Party Claim seeks an order, injunction, or other equitable relief against the Indemnified Party which, if
successful, could materially adversely affect the business, condition (financial or other), capitalization, assets, liabilities, results of operations or prospects of the Indemnified Party. The
Indemnified Party shall make no settlement, compromise, admission, or acknowledgment that would give rise to liability on the part of the Indemnifying Party without the prior written consent of the
Indemnifying Party (which consent shall not be unreasonably withheld, conditioned or delayed). 

        (c)   In
any case in which an Indemnified Party seeks indemnification hereunder and no Third Party Claim is involved, the Indemnified Party shall deliver a Claim Notice to the
Indemnifying Party within a reasonably prompt period of time after an officer of such Indemnified Party or its Affiliates has obtained knowledge of the Loss giving rise to indemnification hereunder.
The failure or delay to so notify the Indemnifying Party shall not relieve the Indemnifying Party of its obligations under this Article 11 except
to the extent such failure results in insufficient time being available to permit the Indemnifying Party to effectively mitigate the resulting Losses or otherwise prejudices the Indemnifying Party. 

44

 

 Section 11.8 Limitations on Indemnities. 

        (a)   Notwithstanding
the foregoing, (i) Seller shall not be obligated to indemnify any Purchaser Indemnified Persons for Losses pursuant to  Section 11.5(a), and Purchaser shall not be obligated to indemnify the
Seller Indemnified Persons for Losses pursuant to  Section 11.6(a), in each case, pursuant to this Article 11 unless and until the amount of
all Losses incurred by any Purchaser Indemnified Persons, or by any Seller Indemnified Persons, as the case may be, exceeds, in the aggregate, $40,000,000 (the "Deductible"), in which event the party
or parties seeking indemnity may recover all Losses incurred in excess of the Deductible, and (i) Seller's maximum liability for Losses pursuant to  Section 11.5(a), and Purchaser's maximum
liability for Losses pursuant to Section 11.6(a),
in each case, shall be $400,000,000 (the "Maximum Indemnity Amount"); provided, however, that, notwithstanding the foregoing, the Deductible and the Maximum Indemnity Amount shall not apply to (and
the Indemnified Parties shall be entitled to be indemnified for all Losses relating to) any claims based on the occurrence of common law actual fraud and (B) any claims asserted under  Section 11.5(a), or Section 11.6(a) insofar as such claims relate to any breach of
Fundamental Representations or any certificate to the extent based on any such Fundamental Representation. 

        (b)   Solely
for purposes of calculating the amount of Losses incurred arising out of or relating to any breach or inaccuracy of a representation or warranty (and not for
determining whether a breach has occurred), the references to "Material Adverse Effect" or other materiality qualifications (or correlative terms) shall be disregarded. 

        (c)   The
liability of any party under Article 11 shall be in addition to, and not exclusive of, any other liability
that such party may have at Law or equity based on such party's common law actual fraud. None of the provisions set forth in this Agreement, including, but not limited to, the provisions set forth in  Section 3.4(j)
 (relating to the Individual Defect Deductible), Section 11.4(b) (relating
to limitations on the period during which a claim for indemnification may be brought) or Section 11.8(a) (relating to the Deductible), shall be
deemed a waiver by any party to this Agreement of any right or remedy which such party may have at Law or equity based on any other party's common law actual fraud, nor shall any such provisions
limit, or be deemed to limit, (i) the amounts of recovery sought or awarded in any such claim for common law actual fraud, (ii) the time period during which a claim for common law actual
fraud may be brought or (iii) the recourse which any such party may seek against another party with respect to a claim for common law actual fraud; provided, that with respect to such rights
and remedies at law or equity, the parties further acknowledge and agree that none of the provisions of this Section 11.8(c), nor any reference
to this Section 11.8(c) throughout this Agreement, shall be deemed a waiver of any defenses which may be available in respect of actions or
claims for common law actual fraud, including but not limited to, defenses of statutes of limitations or limitations of damages. 

 Section 11.9 Release.

 Section 11.11 Waiver of Trade Practices Acts. 

        (a)   It
is the intention of the parties that Purchaser's rights and remedies with respect to this transaction and with respect to all acts or practices of Seller, past,
present or future, in connection with this transaction shall be governed by legal principles other than the Texas Deceptive Trade Practices—Consumer Protection Act, Tex. Bus. & Com.
Code Ann. § 17.41 et seq. (the "DTPA") or the Louisiana unfair trade practices and consumer protection law, La. R.S. 51:1402,  et seq. (the "UTPCPL").
As such, Purchaser hereby waives the applicability of the DTPA and the UTPCPL to this transaction and any and all
duties, rights or remedies that might be imposed by the DTPA and/or the UTPCPL, whether such duties, rights and remedies are applied directly by the DTPA or the UTPCPL itself or indirectly in
connection with other statutes; provided, however, Purchaser does not waive § 17.555 of the DTPA. Purchaser acknowledges, represents and
warrants that it is purchasing the goods and/or services covered by this Agreement for commercial or business use; that it has assets of $5,000,000.00 or more according to its most recent financial
statement prepared in accordance with GAAP; that it has knowledge and experience in financial and business matters that enable it to evaluate the merits and risks of a transaction such as this; and
that it is not in a significantly disparate bargaining position with Seller. 

        (b)   Purchaser
expressly recognizes that the price for which Seller has agreed to perform its obligations under this Agreement has been predicated upon the inapplicability of
the DTPA and the UTPCPL and this waiver of the DTPA and the UTPCPL. Purchaser further recognizes that Seller, in determining to proceed with the entering into of this Agreement, has expressly relied
on this waiver and the inapplicability of the DTPA and the UTPCPL.

        Purchaser

and integral part of this transaction and the consideration thereof. Purchaser acknowledges that this waiver has been brought to its attention and has been explained in detail and that Purchaser has
voluntarily and knowingly consented to this waiver of warranty of fitness and warranty against redhibitory vices and defects for the Assets. 

 Section 11.13 Recording. 

        As
soon as practicable after Closing, Purchaser shall record the Conveyance in the appropriate counties and/or parishes and provide Seller with copies of all recorded or approved
instruments. The Conveyance in the form attached as Exhibit Bis intended to convey all of the Properties being conveyed pursuant to this
Agreement. Certain Properties or specific portions of the Properties that are leased from, or require the approval to transfer by, a Governmental Body are conveyed under the Conveyance and also are
described and covered other separate assignments made by Seller to Purchaser on officially approved forms, or forms acceptable to such entity, in sufficient multiple originals to satisfy applicable
statutory and regulatory requirements. The interests conveyed by such separate assignments are the same, and not in addition to, the interests conveyed in the Conveyance attached as  Exhibit B.
Further, such assignments shall be deemed to contain the special warranty of title of Seller and all of the exceptions, reservations,
rights, titles, power and privileges set forth herein and in the Conveyance as fully and only to the extent as though they were set forth in each such separate assignment.

GUARANTY  

        This Guaranty dated as of December 22, 2006, is made by EXCO Resources, Inc., a Texas corporation ("Guarantor"), in favor of Anadarko Petroleum
Corporation, a Delaware corporation ("APC"), and Anadarko Gathering Company, a Delaware corporation ("AGC"; together with APC hereinafter referred to as "Anadarko"). 

WITNESSETH:  

        WHEREAS, contemporaneously with the execution of this Guaranty, Anadarko and Vernon Holdings, LLC, a Delaware limited liability company and wholly-owned
subsidiary of Guarantor ("Purchaser"), entered into that certain Purchase and Sale Agreement, dated as of even date herewith (as modified from time to time, the "Agreement"); and 

        WHEREAS,
in order to induce Anadarko to enter into the Agreement, and in consideration thereof, Guarantor has agreed to execute this Guaranty. 

        NOW,
THEREFORE, in consideration of the foregoing premises and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Guarantor hereby
agrees as follows: 

Article I

Guaranty  

        Section 1.1    Guaranty.    Subject to Section 1.5, Guarantor unconditionally, absolutely and irrevocably
guarantees to Anadarko, its successors and assigns (without duplication) the full and prompt performance and payment by Purchaser of all covenants required to be performed by Purchaser pursuant to the
terms of the Agreement and/or the documents executed and delivered by Purchaser in connection with the Agreement (collectively, the "Ancillary Documents") and (ii) all other or additional
obligations of Purchaser, or any increases, extensions and rearrangements of the foregoing obligations, under any amendments, supplements, and other modifications to the documents and agreements
creating the foregoing obligations (collectively, the "Obligations"). Guarantor is liable as a primary obligor. If any of the Obligations are not punctually performed or paid when due Guarantor shall
immediately pay or perform or cause the payment or performance of the Obligations that are required and performable. 

        Section 1.2    Guaranty Absolute.    This Guaranty shall be deemed accepted upon receipt by Anadarko. Guarantor hereby
guarantees that the Obligations will be performed strictly in accordance with the terms of the Agreement and the Ancillary Documents. The Obligations constitute a present and continuing guaranty of
payment and performance, and not of collectibility. Subject to Section 1.5, the liability of Guarantor under this Agreement shall be absolute, unconditional, present and continuing until all of
the Obligations have been indefeasibly paid in full or performed, as applicable, irrespective of: 

        (a)   any
assignment or other transfer of the Agreement or any of the Ancillary Documents or any of the rights thereunder of Purchaser therein; 

        (b)   any
amendment, waiver, renewal, extension or release of, or any consent to or departure from or other action or inaction related to, the Agreement or any of the
Ancillary Documents;; 

        (c)   any
amendment, modification, increase, reduction, extension or rearrangement of the Obligations; 

        (d)   any
acceptance by Anadarko of partial payment or performance from Purchaser; 

 

        (e)   any
bankruptcy, insolvency, reorganization, arrangement, composition, adjustment, dissolution, liquidation, or other like proceeding relating to Purchaser, or any action
taken with respect to the Agreement, any of the Ancillary Documents or this Guaranty by any trustee or receiver, or by any court, in any such proceeding; 

        (f)    any
absence of any notice to, or knowledge by, Guarantor, of the existence or occurrence of any of the matters or events set forth in the foregoing subsections
(a) through (e); 

        (g)   all
notices and demands whether of presentment, protest, dishonor or otherwise, other than any notices and demands expressly set forth herein; 

        (h)   any
change in corporate structure, existence or ownership of Guarantor; and 

        (i)    any
other circumstance that might otherwise constitute a defense available to, or a discharge of, a guarantor. 

        Section 1.3    Subrogation Waiver.    Guarantor agrees that it shall not have any rights (direct or indirect) of
subrogation, contribution, reimbursement, indemnification, or other rights of payment or recovery from Purchaser for any payments made by Guarantor hereunder until all Obligations have been paid and
performed, and Guarantor hereby irrevocably waives and releases any such rights of subrogation, contribution, reimbursement, indemnification, and other rights of payment or recovery it may now have or
hereafter acquire against Purchaser until all Obligations have been indefeasibly paid and performed. 

        Section 1.4    Continuing Guaranty.    This Guaranty is a continuing guaranty and shall (i) become effective
immediately and remain in full force and effect until the complete payment and performance of the Obligations, (ii) be binding upon Guarantor and its respective successors and assigns, and
(iii) inure to the benefit of and be enforceable by Anadarko and its respective successors, transferees, and assigns; provided, however, that the obligations of Guarantor hereunder may not be
assigned, transferred, or delegated unless Guarantor remains liable hereunder. 

        Section 1.5    Certain Defenses.    Anadarko agrees that, notwithstanding anything contained herein to the contrary,
Guarantor shall not be obligated to pay or perform any Obligation hereunder to the extent that Purchaser is not required to pay or perform such Obligation as a result of any right of offset, counter
claim, or other defense available to Purchaser with respect to the Agreement (collectively, a "Purchaser Defense"). In furtherance thereof, Guarantor shall be entitled to assert, as a valid defense to
the payment or performance of any Obligation hereunder, any Purchaser Defense to the same extent that any such Purchaser Defense could be asserted by Purchaser in any action brought to enforce the
Obligations against Purchaser. 

        Section 1.6    Collection.    The obligations of Guarantor hereunder are in no way conditional or contingent upon any
requirement on the part of Anadarko to first attempt to enforce, require the payment of, or collect any of the Obligations from or against Anadarko or any other Person or to attempt to collect any of
the Obligations by any other means. 

Article II

Representations and Warranties  

        Section 2.1    Representations and Warranties.    Guarantor represents and warrants to Anadarko as follows: 

        (a)   Guarantor
is a corporation, duly incorporated, validly existing and in good standing under the laws of the State of Texas, and has all requisite corporate power and
authority to own, lease and operate its properties and to carry on its business as is now being conducted. 

S-2

 

        (b)   Guarantor
has the corporate power to enter into, and carry out its obligations under, this Guaranty. The execution, delivery and performance of this Guaranty, and the
consummation of the transactions contemplated hereby, have been duly and validly authorized by all necessary corporate action required on the part of Guarantor, and no other corporate proceedings on
the part of Guarantor are necessary to authorize this Guaranty or to consummate the transactions contemplated hereby. This Guaranty constitutes the valid and legally binding obligation of Guarantor,
enforceable against Guarantor in accordance with its terms, except as such enforceability may be limited by bankruptcy, insolvency, reorganization, moratorium or other similar laws of general
application relating to or affecting the enforcement of creditors' rights and by general equitable principles. 

        (c)   Neither
the execution and delivery of this Guaranty, nor compliance with any provision hereof, nor the consummation of the transactions contemplated hereby, will: 

        (i)    violate,
or conflict with, or result in a breach of any provisions of the certificate of incorporation or by-laws of Guarantor; 

        (ii)   result
in a default (or give rise to any right of termination, cancellation or acceleration) under or conflict with any of the terms, conditions or provisions of any
note, bond, mortgage, indenture, license or agreement or other instrument or obligation to which Guarantor is a party or by which Guarantor may be bound, except for such defaults (or rights of
termination or acceleration) as to which requisite waivers or consents have been obtained or that would not, individually or in the aggregate, materially impair Guarantor's authority, right or ability
to perform its obligations under or consummate the transactions contemplated by this Guaranty; 

        (iii)  violate
any law, rule, regulation, order, writ, injunction, or decree, applicable to Guarantor or any of its assets, except where such violations, individually or in
the aggregate, would not materially impair Guarantor's authority, right or ability to perform its obligations under or consummate the transactions contemplated by this Guaranty; or 

        (iv)  require
consent or approval of, filing with, or notice to any Person which, if not obtained, would prevent Guarantor from performing its obligations hereunder. 

Article III

Miscellaneous  

        Section 3.1    No Waiver.    No failure or delay on the part of Anadarko in exercising any right, power, or remedy
under this Guaranty shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power, or
remedy. 

        Section 3.2    Amendment.    This Guaranty may not be amended or modified except by an instrument in writing signed by
or on behalf of Guarantor and Anadarko. 

S-3

 

        Section 3.3    Notices.    All notices which are required or may be given pursuant to this Guaranty shall be
