ARTICLE 2

PURCHASE PRICE

Section 2.01 Purchase Price. The total consideration for the purchase, sale, and conveyance of the Assets to Buyer and Buyer’s assumption of the Assumed Obligations and all other liabilities provided for in this Agreement, is Buyer’s payment to Seller of the sum of Five Hundred Twenty-Five Million Dollars ($525,000,000.00) (the “Purchase Price”), as adjusted in accordance with the provisions of this Agreement.

Section 2.02 Deposit.

(a) Concurrently with the execution of this Agreement by Buyer and Seller, Buyer shall deliver to Seller in immediately available funds a performance guarantee deposit in an amount equal to Fifty-Two Million Five Hundred Thousand Dollars ($52,500,000.00) (the “Deposit”) in accordance with wire transfer instructions provided by Seller to Buyer.

(b) Subject to the proviso set forth in Section 11.01, if this Agreement is terminated by Seller pursuant to Section 11.01(b) and Seller does not waive the non-satisfaction of any conditions to Closing set forth in ARTICLE 8, Seller shall retain the Deposit as liquidated damages, which remedy shall be the sole and exclusive remedy available to Seller for Buyer’s failure to perform its obligations under this Agreement, 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 and Buyer shall have no further liability or obligation hereunder. 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.

(c) 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), Section

11.01(g), Section 11.01(h) or Section 13.03(c), then Seller shall promptly return the Deposit to Buyer in immediately available funds pursuant to wire transfer instructions to be provided timely by Buyer to Seller within three (3) business days after the event giving rise to such return

obligation. Buyer and Seller shall thereupon have the rights and obligations set forth elsewhere herein.

(d) 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 shall return the Deposit to Buyer within three

Exhibit 2

(3) business days after its receipt of Buyer’s written demand for the return of the Deposit in accordance with this Agreement, or (ii) Buyer shall have the right to pursue specific performance of this Agreement, provided that Buyer must file an action for specific performance within twenty-one (21) days of Seller’s Breach. If Buyer elects to pursue specific performance, Buyer must pursue specific performance as its sole and exclusive remedy in lieu of all other legal and equitable remedies. If such action for specific performance is not filed within twenty-one (21) days of Seller’s Breach or if Buyer is unsuccessful for any reason other than a Breach of this Agreement by Buyer, Buyer shall be deemed to have waived all legal and equitable remedies and its sole remedy for Seller’s Breach of this Agreement shall be limited to the prompt return of the Deposit.

Section 2.03 Allocated Values. The Purchase Price is allocated among the Assets on a well-by-well basis, including for each Well, PUD Location and PDNP, all as set forth in Exhibit C (the “Allocated Values”). In no event shall the aggregate of the Allocated Values exceed the unadjusted Purchase Price. The term “PUD Locations” means those Proved Undeveloped potential well locations specifically identified in Exhibit C. The term “PDNP” means Proved Developed Not Producing intervals as specifically identified on Exhibit C. 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)(v) of the Treasury Regulations) in order to accomplish the transaction in a manner that will comply, either in whole or in part, with the requirements of a like-kind exchange pursuant to Section 1031 of the Internal Revenue Code of

1986, as amended. Likewise, Buyer shall have the right at any time prior to completion of all the transactions that are to occur at Closing to assign all or a portion of its rights under this Agreement to a Qualified Intermediary for the same purpose. If Seller assigns all or any of its rights under this Agreement for this purpose, Buyer agrees to (a) consent to Seller’s assignment of its rights in this Agreement, which assignment shall be in a form reasonably acceptable to Buyer, and (b) pay the Purchase Price (or a designated portion thereof as specified by Seller) into a qualified escrow or qualified trust account at Closing as directed in writing. If Buyer assigns all

or any of its rights under this Agreement for this purpose, Seller agrees to (i) consent to Buyer’s assignment of its rights in this Agreement, which assignment shall be in a form reasonably acceptable to Seller, (ii) accept the Purchase Price from the qualified escrow or qualified trust account at Closing, and (iii) at Closing, convey and assign directly to Buyer the Assets (or any portion thereof) as directed by Buyer. Seller and Buyer acknowledge and agree that any assignment of this Agreement (or any rights hereunder) to a Qualified Intermediary shall not release any Party from any of its respective liabilities and obligations hereunder, and that neither Party represents to the other Party that any particular tax treatment will be given to any Party as a result thereof. The Party electing to assign

Exhibit 2

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.

ARTICLE 3

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 July 1, 2014 (the “Effective Time”);

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

11:59 p.m. Central Time on September 26, 2014 (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 agent or Representative 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 document 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

Exhibit 2

Permitted Encumbrances) that causes Seller not to have Marketable Title to a particular Lease, including any Well, PUD Location, and PDNP, all as described in Exhibit C. The term “Marketable Title” means such ownership by Seller in the Assets that, subject to and except for the Permitted Encumbrances, is free of restrictions that would prevent the development of Hydrocarbons from the Subject Interests consistent with current practices and:

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

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

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

Section 4.03 Notice of Title Defects. Buyer shall provide Seller notice of all purported Title Defects no later than 11:59 p.m. Central Time on the Notification Date; provided, however, that (1) Buyer agrees that it will use reasonable efforts to furnish Seller, at the end of each week 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 or constitute a breach of this Agreement. 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) 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 4.14. Any matters identified by Buyer prior to or on the Notification Date that constitute Title Defects, but of which Seller has not been specifically notified by Buyer in accordance with the foregoing, shall be deemed to have been waived by Buyer for all purposes and shall constitute Permitted Encumbrances and Assumed Obligations. On September 29, 2014, the Parties shall meet and determine upon which of the Title Defects, Title Defect Values, and methods of cure the Parties have reached agreement. “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 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,

Exhibit 2

or operations on or in connection with such Asset. Upon the receipt of such notice from Buyer, Seller shall have the option, but not the obligation, for a period ending ninety (90) days after the Closing to cure such 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 Lease, including any Well, PUD Location and PDNP, 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 Leases, Xxxxx, PUD Locations, and PDNPs or other Assets affected thereby;

Exhibit 2

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

(viii) Notwithstanding the provisions of this Section 4.03 to the contrary, the Title Defect Value of any Title Defect comprising a required consent not obtained (other than consents customarily obtained after Closing) shall be determined pursuant to Section 4.07 and Section 7.05; and

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

(b) The term Title Defect shall not include (i) those matters deemed not to impair marketability in accordance with the applicable Colorado title standards, or (ii) any assertion, claim or contention of any kind that any Lease has terminated due to a lack of production in paying quantities.

Section 4.04 Remedies for Title Defects.

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

(b) Notwithstanding anything to the contrary in this Section 4.04, if any Title Defect is in the nature of a consent to assignment that is not obtained or other restriction on assignment, the provisions of Section 4.07 and Section 7.05 shall apply.

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

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

Exhibit 2

Section 4.05 Special Warranty of Title. Except as to the fee interests among the Assets, the transfer of the Assets by Seller to Buyer shall be accomplished with an Assignment and Bills of Sale (an “Assignment”) in the form of Exhibit D. Special Warranty Deeds in the form of Exhibit E-1 and Exhibit E-2 (the “Special Warranty Deeds”) will be used to convey to Buyer Seller’s fee surface estate interests among the Garfield Properties. A special warranty mineral deed in the form of Exhibit E-3 (the “Special Mineral Deed”) will be used by Seller to convey to Buyer all of Seller’s fee Hydrocarbon interests among the Garfield Properties.

(a) The Assignment, the Special Warranty Deed and the Special Mineral Deed shall each be effective as of the Effective Time and shall each provide for a special warranty of title, by, through, and under Seller, subject to the Permitted Encumbrances and the terms of this Agreement. The term “Permitted 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 (i) reduce the Net Revenue Interest of Seller in any Lease, Well, PUD Location and PDNP as reflected in Exhibit C, or (ii) increase the proportionate share of costs and expenses of leasehold operations attributable to or to be borne by the Working Interest of Seller with respect to any Lease as reflected in 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, guidances, 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 (i) reduce the Net Revenue Interest of Seller in any Lease, Well, PUD Location and PDNP as reflected in Exhibit C, or (ii) increase the proportionate share of costs and expenses of leasehold operations attributable to or to be borne by the Working Interest of Seller with respect to any Lease, Well, PUD Location and PDNP as reflected in Exhibit C, unless there is a proportionate increase in Seller’s applicable Net Revenue Interest;

(iv) preferential rights to purchase or similar agreements (i) with respect to which (A) waivers or consents are obtained from the appropriate parties for the transaction contemplated hereby, or (B) required notices have been given for the transaction contemplated hereby to the holders of such rights and the appropriate period for asserting such rights has expired without an exercise of such rights, or (ii) not exercised prior to Closing, subject to Section 4.06;

Exhibit 2

(v) required third party consents to assignments or similar agreements with respect to which (i) waivers or consents have been obtained from the appropriate parties for the transaction contemplated hereby, or (ii) 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;

(vi) 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;

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

(viii) conventional rights of reassignment contained in any Leases, or assignments thereof, providing for reassignment upon a decision to surrender or abandon any Leases;

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

(x) 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;

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

(xii) such Title Defects as Buyer has waived;

(xiii) 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 as provided in Section 10.07(e); and

(xiv) any claim, assertion, contention or claim that any Lease has expired due to a lack of production in paying quantities.

Exhibit 2

Section 4.06 Preferential Rights to Purchase.

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

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

(c) If a third party who has been offered an interest in any Asset pursuant to a preferential right to purchase elects prior to the Closing to purchase all or part of such Assets, and the closing of such transaction does occur on or before the Closing Date, then the interest or part thereof so affected will be excluded from the Assets and the Purchase Price shall be reduced by the Allocated Value of such Assets without the requirement for Buyer to give notice. If any such third party has elected to purchase all or a part of an interest in any Asset subject to a preferential right to purchase but has failed to close the transaction by the Closing Date, or if the election period has not run and no election has been made, then the affected portion of the Assets shall be excluded from the Assets and the Purchase Price shall be reduced by the Allocated Value of such affected Assets. If the election period passes without the exercise of such preferential right to purchase or if any election previously exercised is rescinded in writing by the party previously electing to purchase this affected Asset, all such Assets will be conveyed to Buyer and Buyer shall pay the portion of the Purchase Price therefor.

Section 4.07 Consents to Assignment. The Leases and Surface Agreements subject to a consent to assign are listed on Schedule 4.07. All other Contracts subject to a consent to assign are listed on Schedule 4.07A. The consents to assignment listed on Schedule 4.07A shall be governed solely by Section 7.04 below:

(a) Certain of the Leases and Surface Agreements listed on Schedule 4.07 provide, in words or substance, that any assignment of such instrument without the consent holder’s approval shall be null and void and/or constitute a breach of such instruments (“Hard Consents”). Certain other of the Leases and Surface Agreements listed in Schedule 4.07 provide, in words or substance, that any assignment of such instrument shall be made only with consent holder’s approval, which consent may not be unreasonably withheld (“Soft Consents”).

(b) Promptly after the execution of this Agreement, Seller shall send to each consent holder identified on Schedule 4.07 a request that each such holder consent to the assignment of his, her, their or its instrument to Buyer. Except for out-of-pocket costs incurred to send and monitor the return of these consents to assignment, Seller shall have no obligation to pay any consideration necessary to obtain any consent.

(c) If the consent to assignment by the holder of any Hard Consent or Soft Consent is properly and timely denied prior to the Closing, the affected Asset shall be retained by Seller, and the Purchase Price shall be reduced by the Allocated Value of such Asset without the requirement for Buyer to give notice.

Exhibit 2

(d) If, as of the Closing Date, the time for a holder of a Hard Consent to approve an assignment of a Lease or Surface Agreement has not elapsed, the affected Asset shall be retained by Seller, and the Purchase Price shall be reduced by the Allocated Value of such Asset without the requirement for Buyer to give notice.

(e) If, as of the Closing Date, no response is received from the holder of a Soft Consent, such holder shall be conclusively deemed to have consented to the assignment of his, her, their or its Lease or Surface Agreement, in which event such Asset shall be transferred at Closing and Buyer shall pay the Allocated Value thereof at Closing. From and after Closing Buyer shall have fully responsibility for any Claim that may be later asserted by any such consent holder contesting the validity of the assignment of his, her, their or its instrument.

(f) If any holder of a Hard Consent or a Soft Consent prior to Closing attaches conditions to the granting of a consent or denies such consent, the Parties shall confer as to the appropriate response thereto. If a Soft Consent is denied on inappropriate grounds, it will be deemed to have been granted.

(g) If, prior to the Final Settlement Date, Seller obtains any consent that had been previously denied or Hard Consents that were not resolved prior to the Closing, Seller shall convey the affected Asset using the appropriate Assignment(s). Within seven (7) days of the receipt of such an Assignment and a copy of the consent, Buyer shall pay Seller the Allocated Value therefor, as adjusted pursuant to the terms of this Agreement.

Section 4.08 Remedies for Title Benefits.

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

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

A = Allocated Value for the affected Asset

B = Correct Net Revenue Interest for the affected Asset

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

(b) If the Title Benefit represents a decrease in Working Interest for which there is not a proportionate decrease in Net Revenue Interest, the amount of the Title Benefit Value shall be determined by taking into account the Allocated Value of the affected Asset, the portion of the Asset affected by the Title Benefit, the legal effect of the Title Benefit, the potential discounted

Exhibit 2

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.

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

Section 4.09 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, but not limited to, Phase I testing (but not Phase II testing) (as those terms are defined by the American Society for Testing and Materials) environmental assessments of the Assets, including, but not limited to, 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;

(i) The cost and expense of Buyer’s Environmental Review shall

be borne solely by Buyer;

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

(iii) Buyer shall give Seller notice not less than 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;

(iv) Buyer shall provide Seller a copy of any Phase I reports

affecting the Assets promptly after Buyer’s receipt of the same;

(v) 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;

Exhibit 2

(vi) 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

(vii) 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), STRICT LIABILITY OR OTHER LEGAL FAULT OF SELLER OR ANY OF SELLER’S REPRESENTATIVES) arising out of or relating to Buyer’s Environmental Review. The release and indemnity provisions of this Section 4.09 shall survive termination or Closing of this Agreement notwithstanding anything to the contrary provided for in this Agreement.

(b) Unless otherwise required by applicable Laws, Buyer shall treat any matters revealed by Buyer’s Environmental Review and any environmental review provided by Seller to Buyer, including any analyses, compilations, studies, documents, reports, or data prepared or generated from such review, 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 4.09. If Buyer or any third party to whom Buyer has provided any Environmental Information is requested, compelled, or required to disclose any of the Environmental Information 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

4.09(b) shall survive any termination of this Agreement, notwithstanding anything to the contrary.

Section 4.10 Definitions Used in ARTICLE 4 and in this Agreement.

(a) Environmental Defects. The term “Environmental Defect” shall mean, with respect to any given Asset (including, without limitation, 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 jurisdiction in which such Asset is located.

(b) Governmental Authority. The term “Governmental Authority” shall mean the United States and any state, county, city, and political subdivisions that exercises jurisdiction over

Exhibit 2

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 wildlife or the environment including, without limitation, the Clean Air Act, as amended, the Clean Water Act, as amended, the Comprehensive Environmental, Response, Compensation, and Liability Act of 1980, as amended (“CERCLA”), the Federal Water Pollution Control Act, as amended, the Resource Conservation and Recovery Act of 1976, as amended (“RCRA”), the Safe Drinking Water Act, as amended, the Toxic Substances Control Act, as amended, the Hazardous & Solid Waste Amendments Act of 1984, as amended, the Superfund Amendments and Reauthorization Act of 1986, as amended, the Hazardous Materials Transportation Act, as amended, the Oil Pollution Act of 1990 (“OPA”), any state laws implementing the foregoing federal laws, or equivalent or analogous state or local laws, statutes or ordinances, any regulation promulgated thereunder, including, but not limited to, 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.

Section 4.11 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 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 Environmental Defect Value provisions of Section 4.14. Any matters that may constitute Environmental Defects, but of which Seller has not been specifically notified by Buyer in accordance with the foregoing, together with any environmental matter that does not constitute an Environmental Defect, shall be deemed to have been waived by Buyer for all purposes and constitute an Assumed Obligation. Upon receipt of notices of Environmental Defects, the Parties shall meet and determine upon which of the Environmental Defects, Environmental Defect Values, and methods of correction the Parties have reached agreement. Upon the receipt of such effective notice from Buyer, Seller shall have the option, but not the obligation, to attempt to correct to Buyer’s reasonable satisfaction such Environmental Defect during a period expiring ninety (90) days after Closing.

Exhibit 2

Section 4.12 Remedies for Environmental Defects.

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

30 days of Closing as to the validity of the Environmental Defect, the Environmental Defect Value, or the manner of correction, submit such matter to be determined by an Independent Expert pursuant to Section 4.13.

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

Assets to Buyer. If the Environmental Defect Value or the cost to cure an Environmental Defect is determined to be greater than the Allocated Value of the affected portion of the Assets, Seller shall retain the affected portion of the Assets, and the Purchase Price shall be reduced by the Allocated Value attributable to such portion of the Assets.

Section 4.13 Independent Experts.

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

Exhibit 2

4.04, Section 4.08, Section 4.12, and Section 4.14, be submitted by a Party, with written notice to the other Party, to an independent expert (the “Independent Expert”), who shall serve as the sole and exclusive arbitrator of any such dispute. The Independent Expert shall be selected by the Parties (acting reasonably and in good faith) within 15 days following the effective date of said notice. The Independent Expert shall be a person who is independent, impartial, and knowledgeable in the subject matter and substantive laws involved. For example, but not by way of limitation, in the case of a dispute concerning an alleged Environmental Defect, Environmental Defect Value, or cure of the same, the Independent Expert shall have expertise in both the applicable Environmental Laws and environmental science relating to the oil and gas industry.

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

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

All Title Defects and Environmental Defects asserted by Buyer pursuant to this ARTICLE 4 after being resolved in accordance with this ARTICLE 4 shall thereafter constitute Permitted

Section 7.08 Parent Guarantee. It is acknowledged and agreed that Parent Guarantor’s guarantee of Buyer’s performance of Buyer’s obligations hereunder is a material inducement for Seller to proceed with the execution of this Agreement and the consummation of the transaction contemplated herein.

Exhibit 2

ACTION, WILLFUL MISCONDUCT, OR FRAUD BY THE INDEMNIFIED PARTY), STRICT LIABILITY, OR OTHER LEGAL FAULT OF THE INDEMNIFIED PARTY OR ANY OF ITS REPRESENTATIVES.

(c) NEITHER BUYER NOR SELLER SHALL BE ENTITLED TO RECOVER FROM THE OTHER PARTY, RESPECTIVELY, AND EACH PARTY RELEASES THE OTHER PARTY FROM AND WAIVES, ANY LOSSES, COSTS, EXPENSES, OR DAMAGES ARISING UNDER THIS AGREEMENT OR IN CONNECTION WITH OR WITH RESPECT TO THE TRANSACTIONS CONTEMPLATED IN THIS AGREEMENT ANY AMOUNT IN EXCESS OF THE ACTUAL COMPENSATORY DAMAGES SUFFERED BY SUCH PARTY EXCEPT THAT IF THE DISPUTE BETWEEN SELLER AND BUYER IS BASED ON A FAILURE OF THE TRANSACTION CONTEMPLATED HEREBY TO CLOSE, THE SOLE AND EXCLUSIVE REMEDIES SHALL BE THOSE PROVIDED FOR IN SECTION 2.02. 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. BUYER AND SELLER ACKNOWLEDGE THAT THIS STATEMENT IS CONSPICUOUS.

Section 12.09 Notices and Defense of Indemnified Claims. Each Party shall immediately notify the other Party of any Claim of which it becomes aware and for which it is entitled to indemnification from the other Party under this Agreement. The indemnifying Party shall be obligated to defend, at the indemnifying Party’s sole expense, any litigation or other administrative or adversarial proceeding against the indemnified Party relating to any Claim for which the indemnifying Party has agreed to release and indemnify and hold the indemnified Party harmless under this Agreement; provided, however, that the failure to give such notice shall not relieve the

Exhibit 2

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. An indemnified Party shall use reasonable commercial efforts to pursue, and to cause its affiliates to pursue, all insurance claims to which it may be entitled in connection with any Claims for which a claim for indemnification is made, and the Parties shall cooperate with each other in pursuing insurance claims with respect to any such Claims or any indemnification obligations from third parties with respect to any such Claims. If the indemnifying Party makes any payment on any third party Claim, the indemnifying Party shall be subrogated, to the extent of such payment, to all rights and remedies of the indemnified Party to any insurance benefits or other claims of the Indemnified Party with respect to such third party Claim.

Section 12.10 Survival.

Except as expressly provided in Section 12.02(b), the covenants and agreements of the Parties set forth in this Agreement shall survive the Closing until such covenants and agreements (including, but not limited to, 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.

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 UNDER THIS AGREEMENT, INCLUDING, WITHOUT LIMITATION, ITS INDEMNIFICATION OBLIGATIONS UNDER THIS ARTICLE 12

Section 12.12 Representation as to Title and Environmental Matters. Notwithstanding the survival of certain of Seller’s representations and warranties for a six-month 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 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.

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), or willful misconduct.

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 which 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.

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

Exhibit 2

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

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

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

(d) The omission of certain provisions of this Agreement from the Assignment does not constitute a conflict or inconsistency between this Agreement and the Assignment, and will not effect a merger of the omitted provisions. To the fullest extent

permitted by Laws, all provisions of this Agreement are hereby deemed incorporated into the

Assignment by reference.

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

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

(g) The term “knowledge” whether or not capitalized, shall mean with respect to (a) Seller the actual knowledge (without duty of inquiry) of any of Xxxxx X. Xxxxxxx (Senior Vice President Accounting), Xxxxxxxx X. Xxxxxx (Vice President-Land), Xxxxx X. Xxxxxxx (Senior Vice President-EHS, Regulatory and Government Affairs) and Xxxxx X. Shed (Vice President- Production), and (b) as to Buyer, the actual knowledge (without duty of inquiry) of any of Xxxxx Xxxxx (President and Chief Executive Officer) and Xxxx Xxxxxx (Director of Acquisitions).

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

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

Exhibit 2

(i) Fluctuations in commodity prices;

(ii) Changes in Laws or Environmental Laws; or
