This Purchase and Sale Agreement (this “Agreement”) is made and entered into this 22^nd day of October, 2013, by and between ▇▇▇▇ ▇▇▇▇▇▇▇ CORPORATION, a Delaware corporation (“Seller”), on the one hand, and ENERVEST ENERGY INSTITUTIONAL FUND XIII-A, L.P., ENERVEST ENERGY INSTITUTIONAL FUND XIII-WIB, L.P., and ENERVEST ENERGY INSTITUTIONAL FUND XIII-WIC, L.P., each a Delaware limited partnership, (collectively, “Buyer”), on the other hand. Seller and Buyer are collectively referred to herein as the “Parties,” and are sometimes referred to individually as a “Party.”

R E C I T A L S:

WHEREAS, Seller owns certain oil and gas leases located in the West Tavaputs area of Utah and certain associated assets as defined and more fully described below in Section 1.02 (collectively, the “Assets”); and

WHEREAS, Seller desires to sell to Buyer, and Buyer desires to purchase from Seller, in their respective undivided proportionate interests set forth opposite each Buyer’s name in Exhibit H hereto (each Buyer’s “Proportionate Share”) the Assets, upon the terms and conditions hereinafter set forth;

NOW, THEREFORE, in consideration of Ten Dollars ($10.00) cash in hand paid and of the mutual benefits derived and to be derived from this Agreement by each Party, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Seller and Buyer hereby agree as follows:

ARTICLE 1

ASSETS

Section 1.01 Agreement to Sell and Purchase. Subject to and in accordance with the terms and conditions of this Agreement, Buyer agrees to purchase the Assets from Seller, and Seller agrees to sell the Assets to Buyer. In addition, Buyer agrees to purchase from Seller and Seller agrees to sell to Buyer an undivided and unrestricted ownership interest in and to all seismic data, records and information related to, associated with or that is a part of the seismic data set described on Exhibit G (the “Seismic”), it being the intent that such interest shall carry all of the rights and benefits of ownership currently held by Seller and that such interest shall not be restricted in any way, including without limitation, by way of use, disclosure, or ability to license or otherwise transfer. Seller represents and warrants to Buyer that it has (and Buyer will have) good and marketable title to the Seismic, free and clear of all liens and encumbrances, and that the transfer of the Seismic to Buyer and Buyer’s undivided and unrestricted ownership of the Seismic (including

without limitation, use, disclosure and ability to license or otherwise transfer) will not infringe upon the rights of any other party.

Section 1.02 Assets. Subject to Section 1.03, the term “Assets” shall mean all of Seller’s right, title and interest in and to:

(a) the oil, gas and other mineral leases described on Exhibit A-1 (collectively referred to as the “Leases” or, singularly, as a “Lease”) and any overriding royalty interests, royalty interests, fee mineral interests, non-working or carried interests, operating rights, and other rights and interests described in Exhibit A-1, together with the lands covered thereby or pooled, communitized or unitized therewith (the “Lands”), and all oil, gas, associated liquids, other hydrocarbons and other lease substances (“Hydrocarbons”) that may be produced and saved from the Leases and from any lands pooled, communitized, or unitized therewith (the Leases, the Lands, and the Hydrocarbons described above being collectively referred to as the “Interests” or, singularly, an “Interest”);

(b) all easements, rights-of-way, servitudes, surface leases, surface use agreements, water disposal or handling agreements, agreements pertaining to water ▇▇▇▇▇, and other rights or agreements related to the use of the surface and subsurface, in each case to the extent used in connection with the operation of the Interests, recorded or unrecorded, including those described on Exhibit A-2 (collectively, the “Surface Agreements”);

(c) to the extent assignable or transferable, all permits, licenses, franchises, consents, approvals, and other similar rights and privileges, in each case to the extent used in connection with the operation of the Interests (collectively, the “Permits”);

(d) those water rights described on Schedule 1.02(d) (collectively, the “Water Rights”);

(e) all equipment, machinery, fixtures, spare parts, inventory, and other personal property (including Seller’s leasehold interests therein subject to any necessary consents to assignment) used in connection with the operation of the Interests or in connection with the production, treatment, compression, gathering, transportation, sale, or disposal of Hydrocarbons and any water, by-products, or waste produced therewith or otherwise attributable thereto produced from or attributable to the Interests; all ▇▇▇▇▇ located on the Leases or the Lands or on lands pooled, communitized, or unitized therewith, whether producing, shut in, or abandoned, and whether for production, produced water injection or disposal, monitoring, or otherwise, and including those ▇▇▇▇▇ described in Exhibit B, together with all of Seller’s interests within the spacing, producing, proration, federal exploratory, enhanced recovery, or governmentally prescribed unit attended to the ▇▇▇▇▇ (collectively, the “▇▇▇▇▇”), and the wellhead equipment, telemetry and SCADA equipment (excluding the server associated with the SCADA equipment), pumps, pumping units, flowlines, gathering systems, pipe, tanks, treatment facilities, injection facilities, disposal facilities, compression facilities, and other materials and supplies used in connection with the Interests

(collectively, the “Equipment”). For the avoidance of doubt, the Assets do not include title to or ownership of the assets that are leased by Seller pursuant to the Sale-Leaseback Agreement, but include the Sale-Leaseback Agreement itself;

(f) to the extent assignable or transferable, (i) all agreements described in Section 1.02(b), and all contracts, agreements, drilling contracts, equipment leases, production sales and marketing contracts, farm-out and farm-in agreements, operating agreements, unit agreements, gas marketing, gas gathering, processing and transportation (intrastate and interstate) agreements, and (ii) equipment leases and rental contracts (including truck lease agreements covering only those trucks used as of the Closing Date by New Employees), and other contracts, agreements, and arrangements relating to the Assets, including the contracts listed on Schedule 5.10 insofar as they relate directly to the Assets described in Section 1.02(a) through Section 1.02(e) (collectively, the “Contracts”), provided, however, that the term “Contracts” shall not include the Leases and the Surface Agreements;

(g) the fee surface interests and related grazing rights described on Schedule 1.02(g) (the “Fee Surface Interests”);

To the extent that any of the foregoing records contain interpretations of Seller, Buyer agrees to rely on such interpretations at its sole risk and without any duty on the part of Seller regarding such interpretations; and

(i) all Production Imbalances, including those set forth on Schedule 1.02(i), as of the Effective Time.

ARTICLE 2

PURCHASE PRICE

Section 2.01 Purchase Price. The total consideration for the purchase, sale, and conveyance of the Assets and the Seismic to Buyer and Buyer’s assumption of the Assumed

Obligations and all other liabilities provided for in this Agreement, is Buyer’s payment to Seller of the sum of Three Hundred Twenty-Five Million Four Hundred Sixty-six Thousand Fifty Dollars ($325,466,050.00) (the “Purchase Price”), as adjusted in accordance with the provisions of this Agreement.

Section 2.02 Deposit.

(o) No later than five (5) business days after the execution and delivery of this Agreement, Purchaser will deliver or cause to be delivered to an account (the “Escrow Account”) with JPMorgan Chase Bank, N.A. (the “Escrow Agent”), a wire transfer in the amount equal to Sixteen Million Two Hundred Fifty-Five Thousand Dollars ($16,255,000.00) (the “Deposit”) to be held, invested, and disbursed in accordance with the terms of this Agreement and an escrow agreement of even date herewith among Seller, Buyer, and Escrow Agent (the “Escrow Agreement”). The balance in the Escrow Account shall be distributed to Seller in accordance with Section 10.07(o) and Section 10.08(j) if the Closing occurs or shall be otherwise distributed in accordance with the terms of this Section 2.02.

(p) Subject to the proviso set forth in Section 11.01, if this Agreement is terminated by Seller pursuant to Section 11.01(b), but only as to a condition to Closing described in Section 8.01, Section 8.02, Section 8.03 or Section 8.04, and Seller does not waive the non-satisfaction of that particular condition to Closing, Seller and Buyer shall promptly instruct the Escrow Agent to distribute the Deposit to Seller as liquidated damages, which remedy shall be the sole and exclusive remedy available to Seller for Buyer’s failure to perform its obligations under this Agreement, and Seller expressly waives any and all other remedies, legal or equitable, that it otherwise may have for Buyer’s breach of this Agreement or failure or refusal to close. Buyer and Seller acknowledge and agree that (i) Seller’s actual damages upon the event of such a termination are difficult to ascertain with any certainty, (ii) the Deposit is a reasonable estimate of such actual damages, and (iii) such liquidated damages do not constitute a penalty.

(q) Subject to the proviso set forth in Section 11.01, if this Agreement is terminated (i) by Buyer pursuant to Section 11.01(c) and Buyer does not waive the non‑satisfaction of any conditions to Closing set forth in ARTICLE 9 or (ii) by Buyer or Seller pursuant to Section 11.01(a), Section 11.01(d), Section 11.01(e), Section 11.01(f) or Section 11.01(g), then Seller and Buyer shall promptly instruct the Escrow Agent to distribute the balance in the Escrow Account to Buyer. Buyer and Seller shall thereupon have the rights and obligations set forth elsewhere herein.

(r) If all conditions precedent to the obligations of Seller set forth in ARTICLE 8 have been met, then notwithstanding any provision in this Section 2.02 to the contrary, if Closing does not occur because Seller wrongfully fails to tender performance at Closing or otherwise Breaches this Agreement in any respect prior to Closing, and Buyer is ready and otherwise able to close, at

Buyer’s sole election, either (i) Seller and Buyer shall promptly instruct the Escrow Agent to distribute the balance in the Escrow Account to Buyer, or (ii) Buyer shall have the right to pursue specific performance of this Agreement, provided that Buyer must give Seller written notice within thirty (30) business days after the date set for Closing in Section 10.01 of Buyer’s election to pursue specific performance. If Buyer elects to pursue specific performance, Buyer must pursue specific performance as its sole and exclusive remedy in lieu of all other legal and equitable remedies. If Buyer fails to timely notify Seller of Buyer’s election to pursue specific performance or if Buyer is unsuccessful for any reason, then Seller and Buyer shall promptly instruct the Escrow Agent to distribute the balance in the Escrow Account to Buyer. Buyer and Seller shall thereupon have the rights and obligations set forth elsewhere herein.

Section 2.03 Allocated Values. The Purchase Price is allocated to the ▇▇▇▇▇ and undeveloped locations on a well-by-well or location-by-location basis, as set forth on Exhibit C (the “Allocated Values”). In no event shall the aggregate of the Allocated Values exceed the unadjusted Purchase Price. Seller and Buyer agree that the Allocated Values shall be used to compute any adjustments to the Purchase Price pursuant to the provisions of ARTICLE 4. Any adjustment to the Purchase Price hereunder shall be reflected in the allocation set forth in Exhibit C consistent with Treasury Regulation Section 1.1060-IT(f). For tax purposes, the Parties agree to report the transactions contemplated by this Agreement in a manner consistent with the terms of this Agreement, including the allocations set forth above as of the Closing Date, and that neither Party will take any position inconsistent therewith, including in any tax return, refund claim, litigation, arbitration, or otherwise.

Section 2.04 Section 1031 Like-Kind Exchange. Seller and Buyer hereby agree that Seller shall have the right at any time prior to completion of all the transactions that are to occur at Closing to assign all or a portion of its rights under this Agreement to a Qualified Intermediary (as that term is defined in Section 1.1031(k)-1(g)(4)(iii) of the Treasury Regulations) in order to accomplish the transaction in a manner that will comply, either in whole or in part, with the requirements of a like-kind exchange pursuant to Section 1031 of the Internal Revenue Code of 1986. Likewise, Buyer shall have the right at any time prior to completion of all the transactions that are to occur at Closing to assign all or a portion of its rights under this Agreement to a Qualified Intermediary for the same purpose. If Seller assigns all or any of its rights under this Agreement for this purpose, Buyer agrees to (a) consent to Seller’s assignment of its rights in this Agreement, which assignment shall be in a form reasonably acceptable to Buyer, and (b) pay the Purchase Price (or a designated portion thereof as specified by Seller) into a qualified escrow or qualified trust account at Closing as directed in writing. If Buyer assigns all or any of its rights under this Agreement for this purpose, Seller agrees to (i) consent to Buyer’s assignment of its rights in this Agreement, which assignment shall be in a form reasonably acceptable to Seller, (ii) accept the Purchase Price from the qualified escrow or qualified trust account at Closing, and (iii) at Closing, convey and assign directly to Buyer the Assets (or any portion thereof) as directed by Buyer. Seller and Buyer acknowledge and agree that

any assignment of this Agreement (or any rights hereunder) to a Qualified Intermediary shall not release any Party from any of its respective liabilities and obligations hereunder, and that neither Party represents to the other Party that any particular tax treatment will be given to any Party as a result thereof. The Party electing to assign all or any of its rights under this Agreement pursuant to this Section 2.04 shall defend, indemnify, and hold harmless the other Party and its Affiliates from all Claims relating to such election.

EFFECTIVE TIME

Section 3.01 Ownership of Assets. If the transactions contemplated hereby are consummated in accordance with the terms and provisions hereof, the ownership of the Assets shall be transferred from Seller to Buyer on the Closing Date, but effective for all purposes as of 7:00 a.m. Mountain Time on August 1, 2013 (the “Effective Time”).

Section 3.02 Production Imbalances. Upon Closing, subject to the adjustments described in Section 10.02(b)(vii), Buyer shall assume the positions of Seller with respect to all gas imbalances and make-up obligations related to the Assets regardless of whether such imbalances or make-up obligations arise before or after the Effective Time, at the wellhead, pipeline, gathering system, or other location, and regardless of whether the same arise under contract or otherwise (“Production Imbalances”). Seller’s Production Imbalance position as of the Effective Time is set forth on Schedule 1.02(i). As a result of such assumption, Buyer shall (a) be entitled to receive any and all benefits that Seller would have been entitled to receive by virtue of its position, including rights to produce and receive volumes of production in excess of volumes that it would otherwise have been entitled to produce and to receive cash gas balancing by virtue of ownership of the Assets, (b) be obligated to suffer any detriments or losses that Seller would have been obligated to suffer by virtue of such position, including the obligation to deliver to others production volumes that would have otherwise been attributable to its ownership of the Assets, to deliver production to purchasers thereof without Buyer receiving full payment therefor, or to make cash balancing payments or to repay any take or pay payments, and (c) be responsible for any and all royalty obligations and other burdens with respect to such Production Imbalances; provided however, nothing in this Section 3.02 shall relieve Seller from any royalty obligation affecting payment Seller has actually received for production occurring prior to the Effective Time.

ARTICLE 4

TITLE AND ENVIRONMENTAL MATTERS

Section 4.01 Examination Period. From the date of this Agreement through 5:00 p.m. Mountain Time on December 3, 2013 (the “Notification Date”), Seller shall permit Buyer and/or its Representatives to examine during normal business days and hours at a location designated by

Seller, all abstracts of title, title opinions, title files, ownership maps, lease, Well, and division order files, assignments, operating, and accounting records and all Leases, Surface Agreements, Permits, Contracts, and other agreements, data, analyses, and information pertaining to the Assets insofar as the same may now be in existence and in the possession of Seller (or Representatives of Seller), subject to such restrictions upon disclosure as may exist under confidentiality or other agreements binding upon Seller and relating to the data. If there are any documents that Seller cannot provide Buyer due to a confidentiality requirement, Seller shall describe to Buyer the withheld documents and cooperate with Buyer to obtain access thereto from the third party if Buyer so requests.

Section 4.02 Title Defects. The term “Title Defect” means any encumbrance on, encroachment on, irregularity in, defect in, or objection to Seller’s ownership of the Assets (excluding Permitted Encumbrances) that causes Seller not to have Marketable Title to a particular Well or undeveloped location, all as described on Exhibit C. The term “Marketable Title” means such ownership by Seller in the Assets (except as to the Fee Surface Interests and the Water Rights) that, subject to and except for the Permitted Encumbrances, is free of restrictions that would prevent the development of Hydrocarbons from the Assets consistent with current practices and:

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

(b) obligates Seller to bear not greater than the percentage set forth on Exhibit C as Seller’s Working Interest of the costs and expenses relating to the exploration, maintenance, development, and operation of any Well or undeveloped location, all without increase throughout the productive life of such Asset, except as specifically set forth on Exhibit C;

(d) entitles Buyer to use, without subjecting Buyer to a valid Claim of trespass, all roads, power lines, pits, reservoirs, and pipelines (water and Hydrocarbon) necessary for the operation of the Assets as they are currently being used by Seller;

(e) as to the Fee Surface Interests, “Marketable Title” means good and marketable title, free and clear of all liens and encumbrances, but subject to the Permitted Encumbrances; and

(f) the Water Rights will be conveyed by either a quitclaim deed or transfer on a Governmental Authority form without any warranty of title, other than that in Section 5.29.

“Net Revenue Interest” means with respect to any Asset as of the Effective Time, the interest in and to all Hydrocarbons produced, saved, and sold from or allocated to such Asset, after giving effect

to all royalties, overriding royalties, production payments, carried interests, net profits interests, reversionary interests, and other burdens upon, measured by, or payable out of, production therefrom. “Working Interest” means with respect to any Asset as of the Effective Time the interest in and to such Asset that is burdened with the obligation to bear and pay costs and expenses of maintenance, development, or operations on or in connection with such Asset.

Section 4.03 Notice of Title Defects. Buyer shall provide Seller notice of all purported Title Defects no later than 5:00 p.m. Mountain Time on the Notification Date; provided, however, that (1) Buyer agrees that it will use reasonable efforts to furnish Seller, as soon as practicable until the Notification Date, written notice of any Title Defect that Buyer discovers or learns about during that week, which notice may be preliminary in nature and supplemented prior to the Notification Date, and (2) the failure of Buyer to give Seller such preliminary notice will not waive any Title Defects. To be effective, such notice must (a) be in writing, (b) be received by Seller on or prior to the Notification Date, (c) describe the Title Defect in reasonable detail (including any alleged variance in the Net Revenue Interest or Working Interest), (d) identify the specific Asset or Assets affected by such Title Defect, (e) include the Title Defect Value and supporting calculations prepared by Buyer in good faith, (f) provide Buyer’s suggested means to address the Title Defect, including any suggested curative work, and (g) comply with the limitations and Title Defect Value qualifications set forth in Section 4.13. ANY MATTERS THAT MAY CONSTITUTE TITLE DEFECTS (EXCEPT THOSE COVERED BY THE SPECIAL WARRANTY OF TITLE SET FORTH IN THE ASSIGNMENT, BY THE WARRANTY IN THE WARRANTY DEEDS TRANSFERRING THE FEE SURFACE INTERESTS OR BY THE REPRESENTATIONS AND WARRANTIES IN SECTION 5.29), BUT OF WHICH SELLER HAS NOT BEEN SPECIFICALLY NOTIFIED BY BUYER IN ACCORDANCE WITH THE FOREGOING, SHALL BE DEEMED TO HAVE BEEN WAIVED BY BUYER FOR ALL PURPOSES AND SHALL CONSTITUTE PERMITTED ENCUMBRANCES AND ASSUMED OBLIGATIONS. Upon the receipt of such notice from Buyer, the Parties shall meet and determine upon which of the Title Defects, Title Defect Values, and methods of cure the Parties have reached agreement. Upon the receipt of such notice from Buyer, Seller shall have the option, but not the obligation, for a period ending thirty (30) days after the Closing to cure such Title Defect. If Seller should not elect to cure a Title Defect, and no aspect of such Title Defect is reasonably in dispute, the Purchase Price shall be adjusted for such Title Defect by the amount of the Title Defect Value.

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

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

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

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


A	= Allocated Value for the affected Asset


B	= Correct Net Revenue Interest for the affected Asset


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

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

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

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

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

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

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

(b) The term Title Defect shall not include those matters deemed not to impair marketability in accordance with the applicable title standards for the State of Utah.

Section 4.04 Remedies for Title Defects.

(a) For any Title Defect noticed pursuant to Section 4.03 that has not been cured at or prior to Closing, the Purchase Price shall, subject to the provisions of Section 4.13, be decreased at Closing by either (i) the amount the Parties acting reasonably and in good faith agree in lieu of a cure of the asserted Title Defect, or (ii) with respect to any Title Defect for which the Parties have not yet agreed as to the validity of the Title Defect, the Title Defect Value, or the manner of cure, then by the amount of the Title Defect Value asserted by Buyer for such uncured or unadjusted Title Defect.

(b) If, at the expiration of thirty (30) days after Closing, the Parties have not agreed upon the validity of any asserted Title Defect, the appropriate cure of the same, or the Title Defect Value attributable thereto, either Party shall have the right to elect to have any such dispute determined by an Independent Expert pursuant to Section 4.12.

(c) Once a Title Defect is cured within the time specified in Section 4.03, by Seller at its sole cost and expense to Buyer’s reasonable satisfaction, or the existence or value of the Title Defect is determined with finality either by agreement between Buyer and Seller or in accordance with Section 4.12, Buyer shall promptly pay to Seller (i) in the case of a Title Defect that is cured, the amount the Purchase Price was decreased at Closing as a result of this previously uncured Title Defect or (ii) in the case of an Asset affected by an unresolved Title Defect and for which the validity of the Title Defect or the Title Defect Value is determined with finality whether by agreement or in accordance with Section 4.12, the difference, if any, between the amount the Purchase Price was decreased at Closing as a consequence of such asserted and unresolved Title Defect and the amount determined with finality.

Section 4.05 Conveyances and Title.

(a) Except for the Fee Surface Interests (which are subject to Section 4.05(b)) and the Water Rights (which are subject to Section 4.05(c)), the transfer of the Assets by Seller to Buyer shall be accomplished with an Assignment and ▇▇▇▇ of Sale (the “Assignment”) in the form of Exhibit D. The Assignment shall provide for a special warranty of title by, through, and under Seller, but not otherwise, subject to the Permitted Encumbrances. The term “Permitted Encumbrances” shall mean any of the following matters to the extent the same are valid and subsisting and affect the Assets as of the Effective Time:

(i) the terms, conditions, restrictions, exceptions, reservations, limitations, and other matters contained in (including any liens or security interests created by law or reserved in oil and gas leases for royalty, bonus, or rental, or created to secure compliance with the terms of) the Contracts, Surface Agreements, Leases, and any other agreements, instruments, documents, and other matters described or referred to in any Exhibit or Schedule hereto; provided, that, such matters do not operate to (A) reduce the Net Revenue Interest of Seller

in any Well or undeveloped location as reflected on Exhibit C, or (B) increase the Working Interest of Seller with respect to any Well or undeveloped location as reflected on Exhibit C, unless there is a proportionate increase in Seller’s applicable Net Revenue Interest;

(ii) any obligations or duties affecting the Assets to any Governmental Authority with respect to any franchise, grant, license, or permit, and all applicable federal, state, and local laws, rules, regulations, guidance, ordinances, decrees, and orders of any Governmental Authority (“Laws”);

(iii) all royalties, overriding royalties, net profits interests, carried interests, production payments, reversionary interests, and other burdens on or deductions from the proceeds of production created or in existence as of the Effective Time, that do not (A) reduce the Net Revenue Interest of Seller in any Well or undeveloped location as reflected on Exhibit C, or (B) increase the Working Interest of Seller with respect to any Well or undeveloped location as reflected on Exhibit C, unless there is a proportionate increase in Seller’s applicable Net Revenue Interest;

(iv) required third-party consents to assignments or similar agreements with respect to which (A) waivers or consents have been obtained from the appropriate parties for the transaction contemplated hereby, or (B) required notices have been given for the transaction contemplated hereby to the holders of such rights and the appropriate period for asserting such rights has expired without an exercise of such rights;

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

(vi) rights reserved to or vested in any Governmental Authority to control or regulate any of the ▇▇▇▇▇ or units included in the Assets and the applicable laws, rules and regulations of such Governmental Authorities;

(vii) conventional rights of reassignment contained in any Leases or any assignment thereof, providing for reassignment upon a decision to surrender or abandon any Leases (as long as the right has not been triggered prior to Closing);

(viii) statutory liens for Taxes or assessments not yet due and delinquent;

(ix) easements, rights‑of‑way, servitudes, permits, surface leases, and other rights with respect to surface operations, on, over or in respect of any of the Assets of which Buyer has notice, either actual, constructive, or inquiry;

(x) materialmen’s, mechanics’, operators’ or other similar liens arising in the ordinary course of business (A) if such liens and charges have not been filed pursuant to law and the time for filing such liens and charges has expired, or (B) if filed, such liens and charges have not yet become due and payable or payment is being withheld as provided by law;

(xi) such Title Defects as Buyer has waived; and

(xii) all deeds of trust and other security interests burdening the Assets granted by Seller in connection with its Third Amended and Restated Credit Agreement dated as of March 16, 2010, as further amended, under which JPMorgan Chase Bank, N.A. serves as administrative agent (the “JPMorgan Chase Liens”), it being understood that the release of the JPMorgan Chase Liens is a condition to the Closing.

(b) The transfer of the Fee Surface Interests among the Assets shall be accomplished by (i) warranty deeds substantially in the form of Exhibit E-1 and Exhibit E‑2 for the Medicine Springs Ranch located in Carbon County, and (ii) a warranty deed substantially in the form of Exhibit E-3 for the Fasselin Ranch located in Carbon and Duchense Counties. The transfer of the related grazing rights shall be accomplished by use of the form required by the appropriate Government Authority (the “Fee Surface Conveyances”). Such Fee Surface Conveyances shall be subject to the Permitted Encumbrances.

(c) The transfer of the Water Rights among the Assets shall be accomplished by (i) quitclaim deeds in substantially the form of Exhibit E-4 (Medicine Springs Ranch, Carbon County) and Exhibit E-5 (Fasselin Ranch, Carbon and Duchense Counties), and (ii) the water permit transfer forms required by the appropriate Governmental Authority (the “Water Rights Conveyances”). The Water Rights Conveyances shall be subject to the Permitted Encumbrances.

Section 4.06 Consents. No consent to assignment is required in connection with any of the Assets, except those consents customarily obtained after a sale or conveyance or as shown on Schedule 7.04.

Section 4.07 Remedies for Title Benefits.

(a) If, prior to the Notification Date, Seller or Buyer obtains knowledge of any Title Benefit affecting the Assets, such Party shall promptly notify the other Party in writing thereof. Seller shall not be entitled to an upward adjustment to the Purchase Price with respect to any Title Benefits; provided, Title Benefits qualifying for adjustment pursuant to Section 4.13 shall be offset against Title Defects qualifying for adjustment pursuant to ARTICLE 4 hereof. The term “Title Benefit” shall mean Seller’s actual Net Revenue Interest in any Well or undeveloped location that is greater than or in addition to the Net Revenue Interest set forth on Exhibit C, or Seller’s actual

Working Interest in any Well or undeveloped location that is less than the Working Interest set forth on Exhibit C (with less than a proportionate decrease in the Net Revenue Interest).

(b) The value attributable to each Title Benefit (the “Title Benefit Value”) that is asserted by either Party in the Title Benefit notices shall be determined based on the criteria set forth below:

(i) If the Title Benefit is that the actual Net Revenue Interest attributable to any Well or undeveloped location is greater than stated on Exhibit C, then the Title Benefit Value shall be the absolute value of the number determined by the following formula:

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


A	= Allocated Value for the affected Asset


B	= Correct Net Revenue Interest for the affected Asset


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

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

(d) If the Parties have not agreed on the amount of the Title Benefit Value of a Title Benefit by the expiration of thirty (30) days after Closing, Seller or Buyer shall have the right to elect to have such Title Benefit Value determined by an Independent Expert pursuant to Section 4.12.

Section 4.08 Environmental Review. From the date of this Agreement through the Notification Date, Buyer may conduct an environmental assessment of the Assets, subject to the following:

(a) Buyer shall have the right to conduct on‑site inspections, including Phase I testing (as that term is defined by the American Society for Testing and Materials) environmental assessments of the Assets, including sampling and analysis of soil, air, surface water, groundwater and waste materials, prior to the end of the Notification Date (“Buyer’s Environmental Review”), and Seller shall provide to Buyer a copy of any environmental review Seller has in its possession subject to the same terms of confidentiality subsequently set forth herein. Buyer shall not conduct Phase II testing (as that term is defined by the American Society for Testing and Materials) of the

Assets prior to Closing without the prior written consent of, and subject to a written protocol with, Seller (which consent and agreement to protocol shall not be unreasonably withheld or conditioned), and any such Phase II testing shall be limited to recognized environmental conditions identified in the Phase I testing or other inspection conducted by Buyer pursuant to the immediately preceding sentence. Buyer shall bear all costs associated with any Phase II testing, and Buyer shall bear all costs to remediate disturbed lands or repairs required because of any Phase II testing conducted on its behalf.

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

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

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

(v) Buyer shall provide Seller a copy of any Phase I reports (and Phase II reports, if obtained), or drafts thereof if a final report is not prepared affecting the Assets promptly after Buyer’s receipt of the same;

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

(vii) Seller shall use commercially reasonable efforts to obtain any third-party consents that are required in order to perform any work comprising Buyer’s Environmental Review; and

(viii) Buyer hereby agrees to release and defend, indemnify, and hold harmless Seller and Seller’s Representatives from and against all Claims made by (or attributable to the acts or omissions of) Buyer or Buyer’s Representatives (INCLUDING THOSE RESULTING FROM THE SOLE, JOINT, OR CONCURRENT NEGLIGENCE (BUT NOT WILLFUL MISCONDUCT OR GROSS NEGLIGENCE), STRICT LIABILITY OR OTHER LEGAL FAULT OF SELLER OR ANY OF SELLER’S REPRESENTATIVES) arising out of or relating to Buyer’s Environmental Review. The release and indemnity provisions of this Section 4.08 shall survive termination or Closing of this Agreement notwithstanding anything to the contrary provided for in this Agreement.

(b) Unless otherwise required by applicable Laws, Buyer shall treat any matters revealed by Buyer’s Environmental Review and any environmental review provided by Seller to Buyer, including any analyses, compilations, studies, documents, reports, or data prepared or generated from such review, but excluding any public information (the “Environmental Information”), as confidential, and, except as provided below, Buyer shall not disclose any Environmental Information to any Governmental Authority, or, prior to Closing, to any other third party, without the prior written consent of Seller. Buyer may use the Environmental Information prior to Closing only in connection with the transactions contemplated by this Agreement. The Environmental Information shall be disclosed by Buyer to only those persons who need to know the Environmental Information for purposes of evaluating the transaction contemplated by this Agreement, and who agree to be bound by the terms of this Section 4.08. If Buyer or any third party to whom Buyer has provided any Environmental Information is requested, compelled, or required to disclose any of the Environmental Information prior to Closing, Buyer shall provide Seller with prompt notice sufficiently prior to any such disclosure so as to allow Seller to file for any protective order, or seek any other remedy, as it deems appropriate under the circumstances. If this Agreement is terminated prior to the Closing, upon Seller’s request Buyer shall deliver the Environmental Information, and all copies thereof and works based thereon, to Seller, which Environmental Information shall become the sole property of Seller. Upon request Buyer shall provide copies of the Environmental Information to Seller without charge. The terms and provisions of this Section 4.08(b) shall survive any termination of this Agreement, notwithstanding anything to the contrary provided for in this Agreement.

Section 4.09 Definitions Used in ARTICLE 4 and in this Agreement.

(a) Environmental Defects. The term “Environmental Defect” shall mean, with respect to any given Asset (including air, land, soil, surface and subsurface strata, surface water, groundwater, or sediments), a violation of or a condition that can reasonably be expected to give rise to a violation of any Environmental Law in effect before the Closing Date in the State of Utah. The term “Environmental Defect” shall not include the March 2010 release at the Dry Canyon Compressor Station which resulted in Hydrocarbon impacts to soil and groundwater, the associated regulatory proceeding, or Seller’s ongoing monitoring and remediation activities at the Station (the “Dry Canyon Environmental Release”).

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

(c) Environmental Laws. The term “Environmental Laws” shall mean any and all laws, statutes, ordinances, rules, regulations, or orders of any Governmental Authority pertaining to health and natural resources (but excluding laws, orders, rules, and regulations that pertain to the prevention

of waste or the protection of correlative rights) and the protection of the environment including the Clean Air Act, the Clean Water Act, the Comprehensive Environmental, Response, Compensation, and Liability Act of 1980 (“CERCLA”), the Federal Water Pollution Control Act, the Resource Conservation and Recovery Act of 1976 (“RCRA”), the Safe Drinking Water Act, the Toxic Substances Control Act, the Hazardous and Solid Waste Amendments Act of 1984, the Superfund Amendments and Reauthorization Act of 1986, the Hazardous Materials Transportation Act, the Oil Pollution Act of 1990 (“OPA”), any state laws implementing the foregoing federal laws, or equivalent or analogous state or local laws, statutes or ordinances, any regulation promulgated thereunder, including those pertaining to the handling of oil and gas exploration and production wastes or the use, maintenance, and closure of pits and impoundments, and all other environmental conservation or protection laws in effect as of the Closing Date hereof that are applicable to the Assets. For purposes of this Agreement, the terms “hazardous substance,” “release,” and “disposal” have the meanings specified in the applicable Environmental Laws as in effect as of the Closing Date.

(d) Environmental Defect Value. For purposes of this Agreement, the term “Environmental Defect Value” shall mean, with respect to any Environmental Defect, the estimated costs and expenses net to Seller’s interest in the affected portion of the Assets to correct and/or remediate such Environmental Defect consistent with applicable Environmental Laws, plus any and all fines, penalties, court and/or administrative costs and other expenses attributable to or arising from the existence of such Environmental Defect.

Section 4.10 Notice of Environmental Defects. Buyer shall provide Seller notice of all Environmental Defects no later than 5:00 p.m. Mountain Time on the Notification Date. To be effective, such notice must (a) be in writing, (b) be received by Seller prior to the expiration of the Notification Date, (c) describe the Environmental Defect in reasonable detail, including the written conclusion of Buyer that an Environmental Defect exists, which conclusion shall be reasonably substantiated by the factual data gathered in Buyer’s Environmental Review, (d) identify the specific Asset or Assets affected by such Environmental Defect, (e) set forth the procedures recommended to correct the Environmental Defect, (f) set forth Buyer’s reasonable, good faith estimate of the Environmental Defect Value, including supporting calculations for such estimate, and (g) comply with the limitations and Environmental Defect Value qualifications set forth in Section 4.13. ANY MATTERS THAT MAY CONSTITUTE ENVIRONMENTAL DEFECTS (EXCEPT THOSE COVERED BY THE REPRESENTATIONS AND WARRANTIES IN SECTION 5.27) BUT OF WHICH SELLER HAS NOT BEEN SPECIFICALLY NOTIFIED BY BUYER IN ACCORDANCE WITH THE FOREGOING SHALL BE DEEMED TO HAVE BEEN WAIVED BY BUYER FOR ALL PURPOSES AND CONSTITUTE AN ASSUMED OBLIGATION. Upon receipt of notices of Environmental Defects, Buyer and Seller shall meet and determine upon which of the Environmental Defects, Environmental Defect Values, and methods of correction they have reached agreement. Upon the receipt of such notice from Buyer,

Seller shall have the option, but not the obligation, to attempt to correct to Buyer’s reasonable satisfaction such Environmental Defect during a period expiring thirty (30) days after Closing.

Section 4.11 Remedies for Environmental Defects.

(a) If, as of the Closing Date, any Asset is affected by an uncured or otherwise unresolved Environmental Defect noticed pursuant to the provisions of Section 4.10, the affected portion of the Assets shall not be sold, transferred, or conveyed to Buyer at Closing, and the Purchase Price shall, subject to the terms of Section 4.13, be decreased by the Allocated Value of the portion of the Assets so affected. With respect to any Environmental Defect as to which Buyer and Seller are unable to agree within thirty (30) days of Closing as to the validity of the Environmental Defect, the Environmental Defect Value, or the manner of correction, either Buyer or Seller may submit such matter for determination by an Independent Expert pursuant to Section 4.12.

(b) With respect to any Asset that is not sold, transferred, or conveyed to Buyer at the Closing pursuant to the terms of Section 4.11(a), after the Closing and at such time as any Environmental Defect Value or the manner of correction for an Environmental Defect is determined and, in either event, the amount thereof is determined to be less than the Allocated Value for the affected portion of the Assets, Seller shall have the right (i) in the case of an Environmental Defect Value determination, to have the Purchase Price reduced by only the Environmental Defect Value as so determined or (ii) in the case of the cure determination, to elect to cure the Environmental Defect to Buyer’s reasonable satisfaction. The consequence of (i) shall be that Buyer will pay to Seller an amount equal to the Allocated Value for the affected Assets minus the Environmental Defect Value and the affected portion of the Assets previously retained by Seller shall be conveyed to Buyer. The consequence of (ii) shall be that upon achieving Buyer’s written acknowledgement that the Environmental Defect has been cured to its reasonable satisfaction, the Allocated Value for such previously retained Asset shall be paid to Seller and the affected portion of the Assets shall be conveyed to Buyer. If no Environmental Defect is determined to exist, Buyer shall pay the Allocated Value attributable to the affected portion of the Assets to Seller, and Seller shall convey the previously retained portion of the Assets to Buyer. If the Environmental Defect Value or the cost to cure an Environmental Defect is determined to be greater than the Allocated Value of the affected portion of the Assets, Seller shall retain the affected portion of the Assets, and the Purchase Price shall be reduced by the Allocated Value attributable to such portion of the Assets.

Section 4.12 Independent Experts.

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

Section 4.04, Section 4.07, Section 4.11, and Section 4.13, be submitted by a Party, with written notice to the other Party, to an independent expert (the “Independent Expert”), who shall serve as the sole and exclusive arbitrator of any such dispute. The Independent Expert shall be selected by Buyer and Seller (acting reasonably and in good faith) within fifteen (15) days following the effective date of said notice. The Independent Expert shall be a person who is independent, impartial, and knowledgeable in the subject matter and substantive laws involved. For example, but not by way of limitation, in the case of a dispute concerning an alleged Environmental Defect, Environmental Defect Value, or cure of the same, the Independent Expert shall have expertise in both the applicable Environmental Laws and environmental science relating to the oil and gas industry.

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

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

(ii) In the event of circumstances described in clause (i) above, Seller at its option may at any time during the 60‑day cure period pursuant to clause (i) (as such period may be extended pursuant to such clause) decline to cure or correct the applicable defect, at which time the applicable remedies set forth in Section 4.11 shall apply.

(c) If Buyer and Seller fail to select an Independent Expert within the 15-day period referred to in Section 4.12(a) above, within three (3) days thereafter, either Buyer or Seller may request the American Arbitration Association to act as the appointing authority and choose a third Independent Expert (meeting the qualifications provided for herein) who alone shall resolve the disputes between Buyer and Seller. Buyer and Seller shall each bear its own costs and expenses incurred in connection with any such proceeding and one-half (1/2) of the costs and expenses of the Independent Expert.

(d) Disputes to be resolved by an Independent Expert shall be resolved in accordance with mutually agreed procedures and rules and, failing such agreement, in accordance with the rules and procedures for non-administered arbitration set forth in the commercial arbitration rules of the American Arbitration Association. The Independent Expert shall be instructed by the Parties to resolve such dispute as soon as reasonably practicable in light of the circumstances using the terms and provisions of this Agreement with respect to title and environmental matters. The decision and

award of the Independent Expert shall be binding upon the Parties and final and non-appealable to the maximum extent permitted by Laws or Environmental Laws, as applicable, and judgment thereon may be entered in a court of competent jurisdiction and enforced by any Party as a final judgment of such court.

(e) All proceedings under this Section 4.12 shall be conducted at a mutually agreed location, or if Buyer and Seller acting reasonably do not mutually agree upon a location for such proceeding, the proceeding shall be conducted in Denver, Colorado.

Section 4.13 Limitation of Remedies For Title Benefits, Title Defects, and Environmental Defects. Notwithstanding anything to the contrary contained in this Agreement,

(h) Buyer acknowledges that Seller owns undivided interests in some or all of the Assets, and Buyer agrees that the acts or omissions of the other working interests owners shall not constitute a violation of the provisions of this ARTICLE 7, nor shall any action required by a vote of working

interest owners constitute such a violation so long as Seller has voted its interests in a manner that complies with the provisions of this ARTICLE 7. Seller will, without penalty for the failure to do so except to the extent that the failure to give Buyer such notice would have a Material Adverse Effect, notify Buyer of the occurrence of such event to the extent of Seller’s knowledge.

Section 7.02 Operating Company’s Qualification. At Closing (or upon termination of the Transition Services Agreement, if utilized), Buyer shall cause Operating Company to be qualified and meet all requirements, including the bonding requirements that have been imposed on Seller that are described on Schedule 5.13, to be designated operator of that portion of the Assets for which Seller serves as operator.

Seller shall make its employees and contractors available to Buyer prior to the Closing as may be reasonably necessary to assist in the transition if Buyer becomes the operator. Seller does not warrant or guarantee that Buyer will become the operator of the Assets or any portion thereof, as such matter will be controlled by the applicable joint operating agreement(s) and other applicable agreement(s); provided, however, Seller shall use reasonable efforts to assist Buyer in becoming successor operator.

Section 7.04 Consent to Assignment of Certain Contracts; Novation of Certain Contracts.

(e) Promptly after the execution of this Agreement, Seller shall send a request for consent to assignment to each holder of a consent right set forth on Schedule 7.04.

Buyer covenants and agrees that it will provide the financial security required by each Transporter. Buyer further covenants and agrees that it will fully cooperate with Seller in obtaining from each Transporter the assignment of each gathering, processing or

transporter Contract, as the case may be, and upon Closing, Buyer shall assume all of Seller’s rights and obligations thereunder, arising from and after the Effective Time.

(g) It is acknowledged and agreed that the firm transportation Contract with Wyoming Interstate Gas Company (“WIC”) has two components, one related to the Overthrust portion thereof, and the other related to the Kanda portion thereof. The Overthrust portion of such Contract is among the Excluded Assets.

In order to accomplish the bifurcation of this WIC Contract and the assignment of the Kanda portion of such Contact, certain approvals and waivers must be obtained from the FERC. Promptly after the execution of this Agreement, the Parties shall cooperate in the filing of appropriate applications with the FERC in order to bifurcate the Overthrust and Kanda portions of the WIC Contract and provide for the assignment of the Kanda portion only to Buyer. If FERC approval of such bifurcation of the WIC Contact and assignment of the Kanda portion thereof is not received by the Closing Date, the Parties shall proceed with Closing, and Seller shall retain the entire WIC Contract and the Parties shall execute at Closing a contract whereby Seller shall purchase from Buyer the Hydrocarbons produced from the Assets, which contract will terminate upon FERC’s approval of the bifurcation of the WIC Contract and the assignment of the Kanda portion thereof to Buyer.

(h) As provided in Section 1.02(e), the Assets do not include, and it is acknowledged and agreed that excluded from the transaction contemplated by this Agreement are, those specific compression-related assets subject to that certain Master Lease Agreement dated July 23, 2012 (Master Lease Agreement Number 24605-9000) by and between Seller and Banc of America Leasing & Capital, LLC, ▇▇▇▇▇ Fargo Equipment Finance, Inc., BMO ▇▇▇▇▇▇ Equipment Finance Company, ▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇ Bank, N.A., U.S. Bank – Equipment Finance and Fifth Third Equipment Finance Company, as assignees thereunder (the “Sale-Leaseback Agreement”), a copy of which has been furnished to Buyer. The Sale-Leaseback Agreement will be amended to bifurcate the obligations thereunder as to assets located in Garfield County, Colorado (which Seller shall retain) and the obligations related to those assets thereunder located in the West Tavaputs area (which Buyer shall assume). Buyer covenants and agrees that it will execute and deliver at Closing an instrument that shall provide for the novation of the Sale-Leaseback Agreement and related assignments whereby (1) Buyer shall assume all of Seller’s rights and obligations thereunder as to only the assets thereunder in the West Tavaputs area and (2) Seller’s liability for any post-Effective Time obligations thereunder as to assets located in the West Tavaputs area shall be terminated. Notwithstanding the foregoing, in the event the amendment and novation of the Sale-Leaseback Agreement is not accomplished on or before the Closing, the Parties shall cooperate in accomplishing such novation on or before the termination of the Transition Services Agreement.

(i) Seller shall have no obligation whatsoever to make any payment, deliver any other consideration, or retain or assume any obligation in order to obtain any consent to assignment or

accomplish the assignment and/or novation of any Contract or the novation of the Sale-Leaseback Agreement.

Section 7.05 Public Announcements. Prior to issuing any press release, a Party shall provide it to the other Party for approval, which approval shall not be unreasonably withheld, conditioned or delayed; however, the foregoing shall not restrict disclosures by Buyer or Seller that are required by applicable securities or other Laws or the applicable rules of any stock exchange having jurisdiction over the disclosing Party or its Affiliates.

BUYER AND SELLER WAIVE, AND RELEASE EACH OTHER FROM ANY RIGHT TO RECOVER PUNITIVE, SPECIAL, EXEMPLARY, AND CONSEQUENTIAL DAMAGES ARISING IN CONNECTION WITH OR WITH RESPECT TO THE TRANSACTIONS CONTEMPLATED IN THIS AGREEMENT; PROVIDED, HOWEVER, ANY SUCH DAMAGES RECOVERED BY A THIRD PARTY (OTHER THAN SUBSIDIARIES, AFFILIATES, OR PARENTS OF A PARTY) FOR WHICH A PARTY OWES THE OTHER PARTY AN INDEMNITY UNDER THIS AGREEMENT SHALL NOT BE WAIVED.

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

Section 12.10 Survival.

(a) The representations and warranties of Seller in ARTICLE 5 (other than the representations and warranties of Seller in Section 5.01, Section 5.02 and Section 5.03, which shall survive the Closing without time limit, and the representations and warranties set forth in Section 5.04 and Section 5.07, which survive the Closing by a period equal to the statute of limitations), shall survive the Closing for a one-year period commencing on the Closing Date.

Except as expressly provided in Section 12.10(b), the covenants and agreements of the Parties set forth in this Agreement shall survive the Closing until such covenants and agreements (including indemnity obligations) have been fully performed in all respects. Representations, warranties and covenants shall be of no further force or effect after the date of their termination.

(b) The indemnity of Seller as provided in Section 12.08 shall survive for a period of one year from and after the Closing, less and except Seller’s indemnity obligation under (i) Section 12.02(b), Section 12.02(c) and Section 12.02(e), which shall survive for a period equal to the statute of limitations from and after Closing and (ii) Seller’s indemnity obligation for the litigation described on Schedule 5.06, Part A, which shall survive until a final non-appealable judgment is entered in each matter described on Schedule 5.06, Part A. Notwithstanding anything herein to the contrary, Buyer shall not be entitled to make any, and hereby waives, the right to assert, any Claim for indemnity pursuant to the terms of this Agreement against Seller unless Buyer seeks indemnification

for such Claim by a written notice received by Seller prior to the expiration of the applicable time period set forth in the prior sentence.

Section 12.11 Limitations on Seller’s Indemnification Obligations. SELLER’S AGGREGATE LIABILITIES FOR INDEMNIFICATION OBLIGATIONS UNDER THIS ARTICLE 12 AND ANY CLAIM OF A BREACH BY SELLER OF ANY REPRESENTATION AND WARRANTY SHALL NOT EXCEED TWENTY PERCENT (20%) OF THE PURCHASE PRICE.

Section 12.12 Representation as to Title and Environmental Matters. Notwithstanding the survival of certain of Seller’s representations and warranties for a one-year period commencing on the Closing Date pursuant to Section 12.10, as to any matter that would constitute a Title Defect or an Environmental Defect that could also result in the Breach of any Seller representation and warranty in ARTICLE 5, then except for the special warranty of title set forth in the Assignment, the warranty in the warranty deeds transferring the Fee Surface Interests and the representations and warranties set out in Section 5.27 and Section 5.29, Buyer’s sole and exclusive remedy shall be to assert prior to the Notification Date such matter as a Title Defect or an Environmental Defect, and the matter will be handled pursuant only to ARTICLE 4. Buyer shall be precluded from asserting any such matter as a Breach of any representation and warranty other than under the special warranty of title set forth in the Assignment, the warranty in the warranty deeds transferring the Fee Surface Interests and the representations and warranties set out in Section 5.27 and Section 5.29.

Section 12.13 Exclusive Remedy. The terms and provisions of this ARTICLE 12 and those provided in ARTICLE 2, ARTICLE 4, ARTICLE 7, ARTICLE 8, ARTICLE 9, ARTICLE 10, and ARTICLE 11 shall be the sole and exclusive remedy of each of the Parties indemnified hereunder with respect to the representations, warranties, covenants, and agreements of the Parties set forth in this Agreement and the other documents executed and delivered hereunder; provided, however, that the terms of this Section 12.13 shall not be applicable to the extent that a Party has committed fraud, securities fraud (where one of the elements of the cause of action is scienter or knowledge), willful misconduct or gross negligence.

Section 12.14 Defenses and Counterclaims. Each Party that is required to assume any obligation or liability of the other Party pursuant to this Agreement or that is required to release and defend, indemnify or hold the other Party harmless hereunder shall, notwithstanding any other provision hereof to the contrary, be entitled to the use and benefit of all defenses (legal and equitable) and counterclaims of such other Party in defense of third-party Claims arising out of any such assumption or indemnification.

Section 12.15 Anti-Indemnity Statute, No Insurance; Subrogation. Buyer and Seller agree that with respect to any statutory limitations now or hereafter in effect affecting the validity or

enforceability of the indemnities provided for in this Agreement, such indemnities shall be deemed amended in order to comply with such limitations. This provision concerning statutory limitations shall not apply to indemnities for all liabilities of the indemnifying Party that are covered by such Party’s insurance. The indemnification provisions provided in this ARTICLE 12 shall not be construed as a form of insurance. Buyer and Seller hereby waive for themselves and their successors and assigns, including their insurers, any rights to subrogation for Claims for which each of them is respectively liable or against which each respectively indemnifies the other, and, if required by applicable policies, Buyer and Seller shall obtain waiver of such subrogation from their respective insurers.
