THIS ASSET ACQUISITION AGREEMENT (as the same may be amended, restated, supplemented or otherwise modified from time to time, this “Agreement”) is entered into the 17^th day of August, 2011, between CNX GAS COMPANY LLC, a Virginia limited liability company (“CONSOL”), and NOBLE ENERGY, INC., a Delaware corporation (“Noble”).

(a) an undivided 50% of all of CONSOL’s right, title and interest in and to the following assets and properties:

(i) the oil, gas and/or mineral leases and oil and gas mineral fee interests more particularly described in Exhibit A, insofar and only insofar as such leases and oil and gas mineral fee interests cover depths within the Marcellus Formation (such 50% of CONSOL’s interest in such leases and oil and gas mineral fee interests as so limited, collectively, the “Leases”), including all working interests, overriding royalty interests, net profits interests, carried interests or similar rights or interest in the Leases, and together with all rights, privileges, benefits and powers conferred upon the holder of the Leases with respect to the use and occupation of the surface of the lands covered thereby that may be necessary, convenient or incidental to the possession and enjoyment of the Leases;

(ii) all oil and gas wells drilled on the Leases or the Units insofar and only insofar as such wells are producing from, or have been drilled to produce from, those depths within the Marcellus Formation, including the oil and gas wells listed on Exhibit B (such 50% of CONSOL’s interest in such wells as so limited, the “Marcellus Wells”) and all fresh water wells, injection wells, salt water disposal wells and other wells of every nature and kind located on the Leases or the Units, in each case, to the extent that they are primarily used in connection with the Marcellus Wells, the Leases or the Units (such 50% of CONSOL’s interest in such wells as so limited, collectively with the Marcellus Wells, the “Wells”);

(iii) all interests in pools or units which include all or a part of any Lease insofar and only insofar as such pools or units cover depths within the Marcellus Formation (such 50% interest in such pools and units, the “Units”);

(iv) to the extent they may be assigned (after exercising commercially reasonable efforts to obtain any and all relevant consents), all permits, licenses, servitudes, easements, rights-of-way, surface use agreements, water access and water use agreements and other similar surface use or water rights, in each case,

to the extent primarily used in connection with the ownership or operation of the Properties, including those set forth in Exhibit C (such 50% of CONSOL’s interest in the foregoing, collectively, the “Rights-Of-Way” and the Leases, Units, Wells and Rights-Of-Way being collectively referred to hereinafter as the “Properties”);

(v) all equipment, machinery, fixtures and other personal property, operational or nonoperational, in each case, to the extent primarily used in connection with the Properties or the other Conveyed Interests, including well equipment, casing, tubing, pumps, motors, machinery, platforms, rods, tanks, boilers, fixtures, manifolds, structures, materials and other items primarily used or held for the use in the operation of the Properties (such 50% of CONSOL’s interest in such properties, the “Personal Property”); and

(vi) all Hydrocarbons produced from or allocated to the Leases, Marcellus Wells or Units on and after the Effective Time.

(b) all of CONSOL’s right, title and interest in and to the following assets and properties to the extent, and only to the extent, that such assets and properties relate to the interests described in subsection (a) above:

(i) to the extent assignable, all Applicable Contracts and all rights thereunder;

(ii) all Well Imbalances relating to the Conveyed Interests;

(iii) copies (in digital form, if available) of the following, to the extent (A) in CONSOL’s or its Affiliates’ possession or (B) to which CONSOL has the right but are in the possession of a Third Party: (1) land and title records (including abstracts of title, title opinions (including title opinions that cover both the Marcellus Formation and other formations) and title curative documents), (2) contract files, (3) correspondence, (4) maps, operations, environmental, production and accounting records, (5) facility and engineering/well files, (6) division order files (including division and interest statements), (7) engineering and/or production files, (8) environmental files, (9) permitting files and (10) geological data, but excluding any of the foregoing items that are primarily used in connection with the ownership or operation of the Excluded Assets (the “Records”); and

(iv) to the extent assignable without payment of fees or other penalties unless Noble agrees to, and does, pay such fees and penalties, all geophysical data, and other seismic and related technical data and information listed on Schedule 2.1.

2.2 Excluded Assets. CONSOL shall reserve and retain all of the Excluded Assets.

2.3 Revenues and Expenses.

(a) For purposes of determining the amount of the adjustment to the Closing Cash Payment provided for in Section 3.2, the principles set forth in this Section 2.3 shall apply except as expressly provided otherwise in this Agreement. Except as expressly provided herein, CONSOL shall remain entitled to all of the rights of ownership (including the right to all production, proceeds of production and other proceeds) and shall remain responsible (by payment, through the adjustments to the Closing Cash Payment hereunder or otherwise) for all Property Expenses, in each case attributable to the Conveyed Interests for the period of time prior to the Effective Time. Except as expressly provided otherwise in this Agreement, and subject to the occurrence of the Closing, Noble shall be entitled to all of the rights of ownership (including the right to all production, proceeds of production, and other proceeds), and shall be responsible (by payment, through the adjustments to the Closing Cash Payment hereunder or otherwise) for all Property Expenses, in each case, attributable to the Conveyed Interests for the period of time from and after the Effective Time. All Property Expenses attributable to the Conveyed Interests, in each case that are: (i) incurred with respect to operations conducted or production produced prior to the Effective Time shall be paid by or allocated to CONSOL and (ii) incurred with respect to operations conducted or production produced from and after the Effective Time shall be paid by or allocated to Noble. Such amounts that are received or paid prior to Closing shall be accounted for in the Preliminary Settlement Statement or Final Settlement Statement as applicable. Such amounts that are received or paid after Closing but prior to the date of the Final Settlement Statement shall be accounted for in the Final Settlement Statement.

(b) If, after the Parties’ agreement upon the Final Settlement Statement, (i) any Party receives monies belonging to the other, including proceeds of production, then such amount shall, within five Business Days after the end of the month in which such amounts were received, be paid over to the proper Party, (ii) any Party pays monies for Property Expenses which are the obligation of the other Party hereto, then such other Party shall, within five Business Days after the end of the month in which the applicable invoice and proof of payment of such invoice were received, reimburse the Party which paid such Property Expenses, (iii) a Party receives an invoice of an expense or obligation which is owed by the other Party, such Party receiving the invoice shall promptly forward such invoice to the Party obligated to pay the same, and (iv) an invoice or other evidence of an obligation is received by a Party, which is partially an obligation of both CONSOL and Noble, then the Parties shall consult with each other, and each shall promptly pay its portion of such obligation to the obligee.

(c) Each of CONSOL and Noble shall be permitted to offset any Property Expenses owed by such Party to the other Party pursuant to this Section 2.3 against revenues owing by such Party to such other Party pursuant to this Section 2.3, but not otherwise.

ARTICLE III

CONSIDERATION

3.1 Consideration. The consideration for (x) the transfer of the Conveyed Interests and the transactions contemplated hereby and (y) the assumption of the Assumed Obligations, shall be comprised of the following two components:

(a) an amount equal to $160,000,000 to be paid at Closing in cash by Noble to a Tax Partnership Account designated by CONSOL (the “Cost Reconciliation Account”) by wire transfer in same day funds for the Marcellus Wells (the “Producing Properties Cash Payment”); and

(b) an aggregate amount equal to $1,066,888,125 to be paid in cash by Noble to the Cost Reconciliation Account by wire transfer in same day funds in three installments: (i) one installment of $355,629,375 to be paid at Closing as and when provided in this Agreement (the “First Cash Payment” and collectively with the Producing Properties Cash Payment, the “Closing Cash Payment”), (ii) one installment of $355,629,375 to be paid on the first anniversary date of Closing (the “Second Cash Payment”), and (iii) one installment of $355,629,375 to be paid on the second anniversary date of Closing (the “Third Cash Payment” and collectively with the Second Cash Payment, the “Post Closing Cash Payments”).

3.2 Adjustments to Closing Cash Payment. The Closing Cash Payment shall be adjusted as follows, and the resulting amount shall be herein called the “Adjusted Closing Cash Payment”:

(a) The Closing Cash Payment shall be adjusted upward by the following amounts (without duplication):

(i) an amount equal to the value of all Hydrocarbons attributable to the Conveyed Interests in storage or existing in stock tanks, pipelines and/or plants (including inventory) as of the Effective Time, the value to be based upon the contract price in effect as of the Effective Time (or if there is no contract price, then the posted price in the field in which such Hydrocarbons were produced or if no such posted price exists for such Hydrocarbons, the market price in the field in which such Hydrocarbons were produced, (in each case) in effect as of the Effective Time), net of (A) amounts payable as Burdens on such production and severance Taxes deducted by the purchaser of such production and (B) expenses (other than Property Expenses) directly incurred in earning or receiving such proceeds and any sale, excise or similar Taxes or fees payable or incurred in connection therewith not reimbursed or reimbursable to CONSOL;

(ii) an amount equal to all Property Expenses and other costs and expenses incurred and paid by or on behalf of CONSOL that are attributable to the Conveyed Interests during the Interim Period, whether paid before or after the Effective Time, including (A) Burdens, (B) rentals and other lease maintenance payments and (C) property, severance and production Taxes and any other Taxes (exclusive of income and franchise Taxes) based upon or measured by the ownership of the Conveyed Interests, the production of Hydrocarbons or the receipt of proceeds therefrom;

(iii) the amount of all prepaid expenses attributable to the Conveyed Interest that are paid or incurred by, or on behalf of, CONSOL that are attributable to the period of time after the Effective Time, including prepaid utility charges, and prepaid ad valorem, property, production, severance and similar Taxes based upon, or measured by the ownership of, the Conveyed Interests or the production of Hydrocarbons or the receipt of proceeds therefrom;

(iv) the amount of all Asset Taxes prorated to Noble in accordance with Section 15.2 but paid or payable by CONSOL; and

(v) any other amount provided for elsewhere in this Agreement or otherwise agreed in writing by CONSOL and Noble.

(b) The Closing Cash Payment shall be adjusted downward by the following amounts (without duplication):

(i) an amount equal to all proceeds received by CONSOL attributable to the sale of Hydrocarbons (A) produced from or allocable to the Conveyed Interests during the Interim Period or (B) contained in storage or existing in stock tanks, pipelines and/or plants (including inventory) as of the Effective Time for which an upward Closing Cash Payment adjustment was made pursuant to Section 3.2(a), (in each case) net of expenses (other than Property Expenses) directly incurred in earning or receiving such proceeds, and any severance, sales, excise or similar Taxes or fees payable or incurred in connection therewith not reimbursed or reimbursable to CONSOL by a Third Party purchaser;

(ii) if CONSOL makes the election under Section 5.3(d)(i) with respect to a Title Defect asserted by Noble prior to Closing, the Title Defect Amount with respect to such Title Defect if such Title Defect Amount has been determined prior to Closing;

(iii) if CONSOL makes the election under Section 6.1(b)(i) with respect to an Environmental Defect asserted by Noble, the Remediation Amount with respect to such Environmental Defect if such Remediation Amount has been determined prior to Closing;

(iv) an amount determined pursuant to Section 4.1(b), Section 5.5(a)(i), Section 5.5(b)(i) or Section 9.1(b)(i) for any Conveyed Interests excluded from the transaction contemplated hereby pursuant to such Sections;

(v) the amount of all Asset Taxes prorated to CONSOL in accordance with Section 15.2 but payable by Noble;

(vi) any amounts payable to Noble pursuant to Section 5.4(c); and

(vii) any other amount provided for elsewhere in this Agreement or otherwise agreed upon by CONSOL and Noble.

3.3 Adjustment Methodology. When available, actual figures will be used for the adjustments to the Closing Cash Payment at Closing. To the extent actual figures are not available, estimates will be used subject to final adjustments in accordance with Section 3.5 and Section 3.6.

3.4 Preliminary Settlement Statement. Not less than five Business Days prior to the Closing, CONSOL shall prepare and submit to Noble for review, using and based on the best information available to CONSOL, a draft settlement statement (the “Preliminary Settlement Statement”) that shall set forth the Adjusted Closing Cash Payment, reflecting each adjustment made in accordance with this Agreement as of the date of preparation of such Preliminary Settlement Statement and the calculation of the adjustments used to determine such amount, together with the designation of CONSOL’s accounts for the wire transfers of funds as set forth in Section 12.3(d). Within three Business Days of receipt of the Preliminary Settlement Statement, Noble will deliver to CONSOL a written report containing all changes with the explanation therefor that Noble proposes to be made to the Preliminary Settlement Statement, if any. The Preliminary Settlement Statement, as agreed upon by the Parties, will be used to adjust the Closing Cash Payment at Closing; provided that if the Parties cannot agree on the Preliminary Settlement Statement prior to the Closing, the Preliminary Settlement Statement as presented by CONSOL will be used to adjust the Closing Cash Payment at Closing.

3.5 Final Settlement Statement. On or before the date that is 120 days following the Closing Date, a final settlement statement (the “Final Settlement Statement”) will be prepared by CONSOL, based on actual revenues and expenses during the Interim Period and which takes into account all final adjustments made to the Closing Cash Payment and shows the resulting final Adjusted Closing Cash Payment. The Final Settlement Statement shall set forth the actual proration of the amounts required by this Agreement. As soon as practicable, and in any event within 30 days after receipt of the Final Settlement Statement, Noble will deliver to CONSOL a written report containing any proposed changes to the Final Settlement Statement and an explanation of any such changes and the reasons therefor (the “Dispute Notice”). Any changes not so specified in the Dispute Notice shall be deemed waived and CONSOL’s determinations with respect to all such elements of the Final Settlement Statement that are not addressed specifically in the Dispute Notice shall prevail. If Noble fails to timely deliver a Dispute Notice to CONSOL containing changes Noble proposes to be made to the Final Settlement Statement, the Final Settlement Statement as delivered by CONSOL will be deemed to be mutually agreed upon by the Parties and will be final and binding on the Parties. If the final Adjusted Closing Cash Payment set forth in the Final Settlement Statement is mutually agreed upon by CONSOL and Noble (or deemed agreed, as the case may be), the Final Settlement Statement and the final Adjusted Closing Cash Payment as so agreed or deemed agreed, shall be final and binding on the Parties, subject to the provisions of Section 2.3(b). Once the final Adjusted Closing Cash Payment has been agreed (or deemed agreed) upon by the Parties pursuant to this Section 3.5 or determined by the Accounting Arbitrator pursuant to Section 3.6, as applicable, then, if the final Adjusted Closing Cash Payment is (a) more than the Adjusted Closing Cash Payment used at Closing pursuant to Section 3.4, Noble shall pay into the Cost Reconciliation Account the amount of such difference, and (b) less than the Adjusted Closing Cash Payment used at Closing pursuant to Section 3.4, CONSOL shall pay to an account designated by Noble the amount of such difference, in each case, by wire transfer in immediately available funds no later than five Business Days after the date such final Adjusted Closing Cash Payment is agreed, or deemed agreed, pursuant to this Section 3.5 or determined pursuant to Section 3.6, as applicable.

3.6 Disputes. If CONSOL and Noble are unable to resolve the matters addressed in the Dispute Notice (if any), each of Noble and CONSOL shall within 14 Business Days after the delivery of such Dispute Notice, summarize its position with regard to such dispute in a written document of 20 pages or less and submit such summaries to the Pittsburgh office of PricewaterhouseCoopers LLP, or if PricewaterhouseCoopers LLP is unable or unwilling to serve as arbitrator and absent agreement by the Parties, by the Pittsburgh, Pennsylvania office of the AAA (the “Accounting Arbitrator”), together with the Dispute Notice, the Final Settlement Statement and any other documentation such Party may desire to submit. Within 20 Business Days after receiving the Parties’ respective submissions, the Accounting Arbitrator shall render a decision choosing either CONSOL’s position or Noble’s position with respect to each matter addressed in any Dispute Notice, based on the materials described above. Any decision rendered by the Accounting Arbitrator pursuant hereto shall be final, conclusive and binding on CONSOL and Noble and will be enforceable against any of the Parties in any court of competent jurisdiction. The costs of such Accounting Arbitrator shall be borne one-half by Noble and one-half by CONSOL. The Final Settlement Statement and final Adjusted Closing Cash Payment determined by the Accounting Arbitrator pursuant to this Section 3.6 shall be final and binding on the Parties (other than with respect to amounts not accounted for therein or settled thereby, which amounts shall be subject to the provisions of Section 2.3(b)).

3.7 Allocated Values. The “Allocated Value” for any Conveyed Interest equals (a) with respect to any Lease (or portion thereof) included in the Conveyed Interests for which there is not an associated Marcellus Well, the applicable Net Acre Allocation with respect to the Conveyed Interest in such Lease, and (b) with respect to any Marcellus Well included in the Conveyed Interests, the amount allocated to the Conveyed Interest in such Marcellus Well on Exhibit B, and, in each case, such Allocated Values shall be used in calculating adjustments to the Closing Cash Payment and Carried Cost Obligation as provided herein.

ARTICLE IV

ACCESS / DISCLAIMERS

4.1 Access.

(a) From and after the date hereof and up to and including the earlier of (i) the date upon which this Agreement is terminated pursuant to the terms hereof and (ii) the date the Records are delivered to Noble pursuant to Section 12.4, but subject to the other provisions of this Section 4.1 and obtaining any required consents of Third Parties, including Third Party operators of the Conveyed Interests (with respect to which consents CONSOL shall use commercially reasonable efforts to obtain), CONSOL shall afford to Noble and its Affiliates and their respective officers, employees, agents, accountants, attorneys, investment bankers, consultants and other authorized representatives (the “Noble Representatives”) reasonable access, during normal business hours, to the Conveyed Interests and all Records and other documents in CONSOL’s or its Affiliates’ possession relating to the Conveyed Interests. CONSOL shall also make available to Noble and the Noble Representatives, upon reasonable notice during normal business

hours, CONSOL’s personnel knowledgeable with respect to the Conveyed Interests in order that Noble may make such diligence investigation as Noble considers necessary or appropriate. All investigations and due diligence conducted by Noble or any Noble Representative shall be conducted at Noble’s sole cost, risk and expense and any conclusions made from any examination done by Noble or any Noble Representative shall result from Noble’s own independent review and judgment. Noble shall coordinate its access rights and physical inspections of the Conveyed Interests with CONSOL to minimize any inconvenience to or interruption of the conduct of business by CONSOL and CONSOL shall have the right to accompany Noble and any Noble Representative in connection with any physical inspection of the Conveyed Interests. Noble shall, and shall cause all Noble Representatives to, abide by CONSOL’s, and any Third Party operator’s safety rules, regulations, and operating policies while conducting its due diligence evaluation of the Conveyed Interests, including any environmental or other inspection or assessment of the Conveyed Interests, and to the extent required by any Third Party operator, execute and deliver any required bonding agreement of such Third Party operator or provide evidence that Noble maintains insurance as may be required by such Third Party operator.

(b) Before conducting any sampling, boring, drilling or other invasive investigation activities with respect to any environmental due diligence (“Invasive Activities”) on or with respect to any of the Conveyed Interests, Noble shall furnish CONSOL with a written description of the proposed scope of the Invasive Activities to be conducted, including a description of the activities to be conducted and a description of the approximate location and expected timing of such activities. If CONSOL reasonably determines that any of the proposed Invasive Activities may unreasonably interfere with normal operation of the Conveyed Interests or the real property and other assets associated with the Conveyed Interests or if CONSOL reasonably determines that it is necessary in order to comply with CONSOL’s safety policies and procedures, CONSOL may require appropriate modification of the proposed Invasive Activity. CONSOL shall notify Noble of any such modification within three Business Days. Any Invasive Activities shall be conducted by a reputable environmental consulting or engineering firm, approved in advance by CONSOL (such approval not to be unreasonably withheld or delayed) and, once approved, such environmental consulting or engineering firm shall be deemed to be a “Noble Representative.” CONSOL shall have the right, at its option, to split any samples collected from the Conveyed Interests with Noble. Notwithstanding anything herein to the contrary, Noble shall not have access to, and shall not be permitted to conduct any environmental due diligence (including any Phase I environmental property assessment) with respect to, any Conveyed Interests where CONSOL does not have the authority to grant access for such due diligence, unless Noble obtains the necessary authority. If CONSOL is unable to grant access to Noble to conduct any Invasive Activities recommended in a Third Party environmental assessment prepared for Noble with respect to any Conveyed Interest, then Noble may, at its option, require CONSOL to retain the affected Conveyed Interests by delivering written notice thereof at least 5 Business Days before the Closing, such Conveyed Interests shall be considered Excluded Assets for all purposes hereunder and the Closing Cash Payment shall be adjusted downward by the Allocated Value of such Conveyed Interests.

(c) Noble hereby Indemnifies each of the operators of the Conveyed Interests and each CONSOL Indemnified Party from and against any and all Liabilities (including any injury, loss or damage arising out of such entry that may occur to Noble or any Noble Representative) arising out of, resulting from or relating to any office visit, field visit, environmental property assessment or other due diligence activity conducted by Noble or any Noble Representative with respect to the Conveyed Interests, EVEN IF SUCH LIABILITIES ARISE OUT OF OR RESULT FROM, IN WHOLE OR IN PART, THE SOLE, ACTIVE, PASSIVE, CONCURRENT OR COMPARATIVE NEGLIGENCE, STRICT LIABILITY OR OTHER FAULT OF, OR THE VIOLATION OF LAW BY, A MEMBER OF THE CONSOL INDEMNIFIED PARTIES, EXCEPTING ONLY LIABILITIES ACTUALLY RESULTING ON THE ACCOUNT OF THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF A MEMBER OF CONSOL INDEMNIFIED PARTIES.

(d) Noble agrees to promptly provide CONSOL, but in any event no later than the earlier of (i) 30 days after receipt or creation of such reports and/or test results or (ii) the date Noble delivers an Environmental Defect Notice which relies, in whole or in part, on such reports and/or test results, copies of all final reports and test results prepared by Noble and/or any Noble Representative, which contain data collected or generated from Noble’s due diligence with respect to the Conveyed Interests, including all environmental and title reports. CONSOL shall not be deemed by its receipt of said reports and/or test results or otherwise to have made any representation or warranty, expressed, implied or statutory, as to the condition of the Conveyed Interests or to the accuracy of said documents or the information contained therein.

(e) Upon completion of Noble’s due diligence, Noble shall at its sole cost and expense and without any cost or expense to CONSOL or its Affiliates, (i) repair any damage to the Conveyed Interests (including the real property and other assets associated therewith) to their approximate condition prior to commencement of Noble’s due diligence or if such repairs are impossible or impracticable, replace the Conveyed Interests affected by such damage; provided that Noble shall only be obligated to make such repairs or replacements to the extent such damage was caused by or arose out of Noble’s due diligence, and (ii) remove all equipment, tools or other property brought onto the Conveyed Interests in connection with Noble’s due diligence. Any material disturbance to the Conveyed Interests (including the real property and other assets associated therewith) resulting from the due diligence conducted by or on behalf of Noble will be promptly corrected by Noble.

(f) During all periods that Noble and/or any of Noble’s Representatives are on the Conveyed Interests, Noble shall maintain, at its sole expense and with insurers reasonably satisfactory to CONSOL, policies of insurance of the types and in the amounts reasonably requested by CONSOL. Coverage under all insurance required to be carried by Noble hereunder will (i) be primary insurance, (ii) list CONSOL Indemnified Parties (other than the shareholders of CONSOL Energy Inc.) as additional insureds, (iii) waive subrogation against CONSOL Indemnified Parties and (iv) provide for 30 days prior notice to CONSOL in the event of cancellation or modification of the policy or reduction in coverage. Upon request by CONSOL, Noble shall provide evidence of such insurance to CONSOL prior to entering the lands underlying the Conveyed Interests.

4.2 Confidentiality. Noble acknowledges that, pursuant to its right of access to the Records or the Conveyed Interests, Noble will become privy to confidential and other information of CONSOL and that such confidential information shall be held confidential by Noble and the Noble Representatives in accordance with the terms of the Confidentiality Agreement. If the Closing should occur, the foregoing confidentiality restriction on Noble, including the Confidentiality Agreement, shall terminate (except as to (a) any Conveyed Interests that are excluded from the transactions contemplated hereby pursuant to the provisions of this Agreement, (b) the Excluded Assets and (c) information related to any assets other than the Conveyed Interests).

ARTICLE V

TITLE MATTERS; CASUALTIES; TRANSFER RESTRICTIONS

5.1 General Disclaimer of Title Warranties and Representations. Except for the special warranty of title contained in the Assignment and subject to and without limiting Noble’s remedies for Title Defects set forth in this Article V, CONSOL makes no warranty or representation, express, implied, statutory or otherwise, with respect to CONSOL’s title to any of the Conveyed Interests and Noble hereby acknowledges and agrees that Noble’s sole and exclusive remedy for any defect of title or any other title matter, including any Title Defect, with respect to any of the Conveyed Interests (a) before the Title Defect Claim Date, shall be as set forth in Section 5.3 and (b) after the Title Defect Claim Date, shall be pursuant to the special warranty of title, to the extent applicable, contained in the Assignment.

5.2 Special Warranty. The Assignment delivered at the Closing will contain a special warranty of title by CONSOL to the Marcellus Wells, Leases and the Subsurface Access Easement pursuant to the terms of the Assignment.

5.3 Notice of Title Defects; Defect Adjustments.

(a) Title Defect Notices. On or before the Title Defect Claim Date, Noble must deliver claim notices to CONSOL meeting the requirements of this Section 5.3(a) (collectively the “Title Defect Notices” and individually a “Title Defect Notice”) setting forth any matters which, in Noble’s reasonable opinion, constitute Title Defects and which Noble intends to assert as a Title Defect pursuant to this Article V. For all purposes of this Agreement and notwithstanding anything herein to the contrary (except for the special warranty of title contained in the Assignment as limited by Section 5.2), Noble shall be deemed to have waived, and CONSOL shall have no liability for, any Title Defect which Noble fails to assert as a Title Defect by a properly delivered Title Defect Notice received by CONSOL on or before the Title Defect Claim Date. To be effective, each Title Defect Notice shall be in writing, and shall include (i) a description of the alleged Title Defect(s), (ii) the Marcellus Wells or Leases affected by the Title Defect (each a “Title Defect Property”), (iii) the Allocated Value of each Title Defect Property, (iv) supporting documents reasonably necessary for CONSOL to verify the existence of the alleged Title Defect(s), and (v) the amount by which Noble reasonably believes the Allocated Value of each Title Defect Property is reduced by the alleged Title Defect(s) and the computations (in reasonable detail) upon which Noble’s belief is based. To give CONSOL an opportunity to commence reviewing and curing Title Defects, Noble agrees to use reasonable efforts to give CONSOL, on or before the end of each calendar month prior to the Title Defect Claim Date, written notice of all Title Defects discovered by Noble during the preceding calendar month, which notice may be preliminary in nature and supplemented prior to the expiration of the Title Defect Claim Date. Noble shall also promptly furnish CONSOL with written notice of any Title Benefit which is discovered by any of Noble’s or any of its Affiliate’s employees, title attorneys, landmen or other title examiners while conducting Noble’s due diligence with respect to the Conveyed Interests prior to the Title Defect Claim Date.

(b) Title Benefit Notices. CONSOL shall have the right, but not the obligation, to deliver to Noble on or before the Title Defect Claim Date with respect to each Title Benefit a notice (a “Title Benefit Notice”) including (i) a description of the Title Benefit, (ii) the Marcellus Wells or Leases affected by the Title Benefit (each a “Title Benefit Property”), and (iii) the amount by which CONSOL reasonably believes the Allocated Value of such Title Benefit Property is increased by the Title Benefit, and the computations upon which CONSOL’s belief is based.

(c) CONSOL’s Right to Cure. CONSOL shall have the right, but not the obligation, to attempt, at its sole cost, to cure any Title Defect of which it has been advised by Noble at any time prior to 180 days following CONSOL’s receipt of a Title Defect Notice with respect to such Title Defect (such date of receipt with respect to each Title Defect, the “Title Defect Notice Date”); provided, however, that, if after the diligent pursuit of other remedies reasonably available to CONSOL to cure any such Title Defect, CONSOL reasonably believes that such Title Defect can be cured through a quiet title or similar proceeding, then the applicable Cure Period with respect to such Title Defect shall be extended to 18 months following the applicable Title Defect Notice Date, notwithstanding CONSOL’s previous attempt to cure such Title Defect without the use of a quiet title or similar proceeding, so long as CONSOL’s initial attempt to cure such Title Defect was diligently pursued and CONSOL initiates the quiet title or similar proceeding on or before the end of the original 180-day Cure Period and diligently pursues such proceeding (the “Cure Period”). In the event that an adjustment for a Title Defect Amount is made to the Closing Cash Payment or the Carry Cost Obligation and CONSOL thereafter cures, during the applicable Cure Period, the Title Defect for which such adjustment was made, then (i) if the adjustment was made to the Closing Cash Payment, Noble shall promptly, but in any event within ten Business Days after such Title Defect has been cured and Noble has received written notice from CONSOL thereof, pay to CONSOL the amount by which the Closing Cash Payment was adjusted on account of such Title Defect, or (ii) if the adjustment was made to the Carry Cost Obligation, then the Carry Cost Obligation shall, within ten Business Days after such Title Defect has been cured and Noble has received written notice from CONSOL thereof, be increased by the amount by which the Carry Cost Obligation was reduced on account of such Title Defect.

(d) Remedies for Title Defects. Subject to (w) CONSOL’s continuing right to dispute the existence of a Title Defect and/or the Title Defect Amount asserted with respect thereto, (x) the rights of the Parties pursuant to Section 14.1(c), (y) the Individual Title Defect Threshold and (z) after decreasing the aggregate Title Defect Amounts by the Title Benefit Amount and the Title Defect Deductible, in the event that any Title Defect timely asserted by Noble in accordance with Section 5.3(a) is not waived in writing by Noble or cured during the Cure Period, CONSOL shall elect to:

(i) for any Title Defect (A) properly asserted by Noble prior to Closing and for which the Title Defect Amount is agreed to prior to Closing, reduce the Closing Cash Payment by an amount determined pursuant to Section 5.3(g) or Section 5.3(j) (the “Title Defect Amount”), or (B) properly asserted by Noble (i) prior to Closing for which the Title Defect Amount is not agreed to prior to Closing or (ii) after Closing, in each case, reduce the Carried Cost Obligation by the Title Defect Amount of such Title Defect;

(ii) upon obtaining Noble’s prior written consent, assume and Indemnify Noble against all Liability (up to the Allocated Value of the affected Conveyed Interest) resulting from such Title Defect with respect to the applicable Conveyed Interests pursuant to an indemnity agreement prepared by CONSOL in a form and substance reasonably acceptable to Noble (a “Title Indemnity Agreement”); or

(iii) with respect to any Title Defect arising on account of there being less than the Minimum Net Acres for any Area, at CONSOL’s sole cost and expense, obtain additional Net Acres by the acquisition of leases and/or oil and gas mineral fee interests within such Area, or agree to assign to Noble a greater percentage of CONSOL’s interest in one or more existing Leases in such Area, in each case, in order to provide Noble with the Minimum Net Acres for such Area; provided that such additional interests obtained by CONSOL pursuant to this Section 5.3(d)(iii) shall contain material terms reasonably similar to, and be of reasonably similar value as, in each case, those interests giving rise to the Title Defect Properties relating to the Title Defect in question.

(e) Remedies for Title Benefits. With respect to each Title Benefit Property reported under Section 5.3(b), the aggregate Title Defect Amounts shall be decreased by an amount equal to the increase in the Allocated Value for the Conveyed Interest attributable to the Title Benefit Property relating to such Title Benefit, as determined pursuant to Section 5.3(h) or Section 5.3(j) (the “Title Benefit Amount”). A Title Benefit shall only be taken into account if Noble has actual Knowledge of such Title Benefit on or prior to the Title Defect Claim Date.

(f) Exclusive Remedy. Except for CONSOL’s special warranty of title contained in the Assignment, and subject to either Party’s rights to terminate this Agreement pursuant to Section 14.1(c), Noble hereby acknowledges and agrees that Section 5.3(d) shall be Noble’s sole and exclusive remedy for any defect of title or any title matter, including any Title Defect, and Noble hereby expressly waives any and all other rights or remedies with respect thereto.

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

(i) if Noble and CONSOL agree on the Title Defect Amount, then that amount shall be the Title Defect Amount;

(ii) if the Title Defect is an Encumbrance that is undisputed and liquidated in amount, then the Title Defect Amount shall be the amount necessary to be paid to remove the Title Defect from the Title Defect Property;

(iii) if the Title Defect represents a discrepancy such that the actual aggregate Net Acres for the applicable Area is less than the Minimum Net Acres for such Area, then the Title Defect Amount shall be the product obtained by multiplying the difference between such Net Acres amounts for the applicable Area by the Net Acre Allocation applicable to such Area;

(iv) if the Title Defect represents an Encumbrance upon, or other Title Defect affecting, the Title Defect Property of a type not described above, the Title Defect Amount shall be determined by taking into account the Allocated Value of the Conveyed Interest attributed to the Title Defect Property, the portion of the Title Defect Property affected by the Title Defect, the legal effect of the Title Defect, the potential economic effect of the Title Defect over the life of the Title Defect Property, the values placed upon the Title Defect by Noble and CONSOL and such other reasonable factors as are necessary to make a proper evaluation; provided, however, that if such Title Defect is reasonably capable of being cured, the Title Defect Amount shall not be greater than the lesser of (A) the reasonable cost and expense of curing such Title Defect and (B) the Allocated Value of the Conveyed Interest attributable to the Title Defect Property;

(v) the Title Defect Amount with respect to a Title Defect Property shall be determined without duplication of any costs or losses included in another Title Defect Amount hereunder; and

(vi) notwithstanding anything to the contrary in this Article V, the aggregate Title Defect Amounts attributable to the effects of all Title Defects upon any Title Defect Property shall not exceed the Allocated Value of the Conveyed Interest attributable to such Title Defect Property.

(h) Title Benefit Amount. The Title Benefit Amount resulting from a Title Benefit shall be determined in accordance with the following methodology, terms and conditions:

(i) if Noble and CONSOL agree on the Title Benefit Amount, then that amount shall be the Title Benefit Amount;

(ii) if the Title Benefit represents a discrepancy such that the actual aggregate Net Acres for any Area is greater than the Minimum Net Acres for such Area, then the Title Benefit Amount shall be the product obtained by multiplying the positive difference between such Net Acres amounts for the applicable Area by the Net Acre Allocation applicable to such Area; and

(iii) if the Title Benefit is of a type not described above, then the Title Benefit Amounts shall be determined by taking into account the Allocated Value of the Title Benefit Property, the portion of such Title Benefit Property affected

by such Title Benefit, the legal effect of the Title Benefit, the potential economic effect of the Title Benefit over the life of such Title Benefit Property, the values placed upon the Title Benefit by Noble and CONSOL and such other reasonable factors as are necessary to make a proper evaluation.

(i) Title Deductibles. Notwithstanding anything to the contrary, (i) in no event shall there be any adjustments to the Closing Cash Payment or the Carried Cost Obligation (as applicable) or any other remedy provided by CONSOL hereunder for any individual Title Defect for which the Title Defect Amount does not exceed $25,000 (the “Individual Title Defect Threshold”); and (ii) in no event shall there be any adjustments to the Closing Cash Payment or the Carried Cost Obligation (as applicable) or any other remedy provided by CONSOL hereunder for any Title Defect for which the Title Defect Amount exceeds the Individual Title Defect Threshold unless (A) the sum of the Title Defect Amounts of all such Title Defects that exceed the Individual Title Defect Threshold, in the aggregate (excluding any Title Defect Amounts attributable to Title Defects cured by CONSOL or for which CONSOL provides an indemnity pursuant to Section 5.3(d)(ii)) less the sum of all the Title Benefit Amounts determined under Section 5.3(h), exceeds (B) the Title Defect Deductible, after which point Noble shall be entitled to remedies for such Title Defects only to the extent that the Title Defect Amounts with respect thereto are in excess of the Title Defect Deductible. For the avoidance of doubt, if CONSOL elects pursuant to Section 5.3(d)(ii) to Indemnify Noble for any Title Defect, then, after such election, relating to the Title Defect for which CONSOL provides an indemnity pursuant to Section 5.3(d)(ii) (x) will not be counted towards the Title Defect Deductible and (y) will be counted for purposes of Section 14.1(c).

(j) Title Dispute Resolution. CONSOL and Noble shall attempt to agree on each Title Defect, Title Benefit, Title Defect Amount and Title Benefit Amount (collectively “Title Disputes”) prior to the applicable Title Dispute Date. If CONSOL and Noble are unable to agree by on any Title Dispute by the applicable Title Dispute Date, then either Party shall have the right to elect, upon written notice to the other Party, to initiate arbitration to resolve such Title Dispute. All Title Disputes shall be exclusively and finally resolved pursuant to this Section 5.3(j). There shall be a single arbitrator, who shall be a title attorney with at least ten years experience in oil and gas titles involving properties in the regional area in which the Title Defect Properties are located (the “Title Arbitrator”). The Title Arbitrator shall be selected by mutual agreement of Noble and CONSOL within 15 days after the election by a Party to utilize the provisions of this Section 5.3(j) with respect to a Title Dispute. If the Parties are unable to mutually agree upon the Title Arbitrator, the Pittsburgh, Pennsylvania office of the AAA shall appoint the Title Arbitrator under such conditions as the AAA in its sole discretion deems necessary or advisable. The place of arbitration shall be Pittsburgh, Pennsylvania, and the arbitration shall be conducted in accordance with the AAA Rules, to the extent such rules do not conflict with the terms of this Section 5.3(j). The Title Arbitrator’s determination shall be made within 30 days after submission of Title Disputes and shall be final and binding upon both Parties, without right of appeal. In making his determination, the Title Arbitrator shall be bound by the rules set forth in Section 5.3(g) and Section 5.3(h) and, subject to the foregoing, may consider such other matters as in the opinion of the Title Arbitrator are necessary to make a proper determination. The Title Arbitrator, however,

may not award (i) Noble a greater Title Defect Amount than the Title Defect Amount claimed by Noble in its applicable Title Defect Notice or (ii) CONSOL a greater Title Benefit Amount than the Title Benefit Amount claimed by CONSOL in the applicable Title Benefit Notice. The Title Arbitrator shall act for the limited purpose of determining the specific Title Disputes submitted by either Party and the Title Arbitrator may not award damages, interest or penalties to either Party with respect to any Title Dispute. CONSOL and Noble shall each bear its own legal fees and other costs of presenting its case to the Title Arbitrator. Each of CONSOL and Noble shall bear one-half of the costs and expenses of the Title Arbitrator. To the extent that the award of the Title Arbitrator with respect to any Title Dispute is not taken into account as an adjustment to the Closing Cash Payment pursuant to Section 3.4 and Section 3.5 and the applicable Party would otherwise be entitled to an adjustment under the provisions of Section 5.3(i), then within ten days after the Title Arbitrator delivers written notice to Noble and CONSOL of his award with respect to a Title Dispute, and subject to Section 5.3(i), (A) the Carried Cost Obligation shall be increased by the amount so awarded by the Title Arbitrator to CONSOL and (B) the Carried Cost Obligation shall be decreased by the amount so awarded by the Title Arbitrator to Noble. Nothing herein shall operate to cause Closing to be delayed on account of any arbitration conducted pursuant to this Section 5.3(j) with respect to any Title Defect properly asserted by Noble prior to the Closing and to the extent any adjustments are not agreed upon by the Parties as of the Closing, the Closing Cash Payment shall not be adjusted therefor at Closing and subsequent adjustments to the Carried Cost Obligation, if any, will be made pursuant to this Section 5.3(j).

5.4 Casualty or Condemnation Loss.

(a) Notwithstanding anything herein to the contrary, from and after the Effective Time if Closing occurs, with respect to the Conveyed Interest, Noble shall assume all risk of loss with respect to (i) production of Hydrocarbons through normal depletion (including watering out of any well, collapsed casing or sand infiltration of any well) and (ii) the depreciation of Personal Property due to ordinary wear and tear, in each case, with respect to the Conveyed Interests and Noble shall not assert such matters as any casualty losses or Title Defects hereunder.

(b) If, after the date of this Agreement but prior to the Closing Date, any portion of the Conveyed Interests is destroyed or damaged by Casualty (other than downhole destruction or impairment through downhole risks) or is taken in condemnation or under right of eminent domain, and the amount of the costs and expenses associated with repairing or restoring the Conveyed Interest(s) affected by such Casualty or taking, determined in the same manner as a Title Defect in accordance with Section 5.3(g), for any Lease, Unit or Marcellus Well taken exceeds 5% of the Total Amount, then Noble shall nevertheless be required to close, and CONSOL shall elect by written notice to Noble prior to Closing either to (i) cause the Conveyed Interest(s) affected by such Casualty or taking to be repaired or restored to at least its condition prior to such casualty or taking, at CONSOL’s sole cost, as promptly as reasonably practicable (which work may extend after the Closing Date), or (ii) treat such Casualty or taking as a Title Defect with respect to the affected Conveyed Interest(s) under Section 5.3. In the event CONSOL elects not to repair or restore the affected Conveyed Interest(s), any dispute

with respect to the value of the Conveyed Interest(s) affected by such Casualty or taking shall be submitted to a “Casualty and Condemnation Arbitrator”, being an attorney with at least ten years experience in oil and gas related matters, and the amount attributable to each such disputed Casualty or taking shall be finally resolved following a procedure substantially similar to that set forth in Section 5.3(j). CONSOL shall retain all rights to insurance and other claims against Third Parties with respect to the Casualty or taking except to the extent the Parties otherwise agree in writing.

(c) If, after the date of this Agreement but prior to the Closing Date, (i) any portion of the Conveyed Interests is destroyed or damaged by Casualty or is taken in condemnation or under right of eminent domain, and the loss as a result of such individual Casualty or taking is 5% of the Total Amount or less, or (ii) any downhole Conveyed Interest (regardless of the amount of loss) is destroyed or otherwise impaired by Casualty, then Noble shall nevertheless be required to close and accept as compensation all sums paid to CONSOL by Third Parties by reason of such Casualty or taking, to the extent attributable to the Conveyed Interests so affected, and CONSOL shall assign, transfer and set over to Noble, or subrogate Noble to, all of CONSOL’s right, title and interest (if any) in any insurance claims, unpaid awards and other rights arising out of such Casualty or taking against Third Parties (other than Affiliates of CONSOL and, as applicable, such Affiliates’ directors, officers, employees and agents), but only to the extent such claims, awards and other rights are attributable to the Conveyed Interests.

5.5 Preferential Purchase Rights and Consents to Assign.

(a) With respect to each Preferential Purchase Right set forth in Schedule 7.10, prior to Closing, CONSOL shall send to the holder of each such Preferential Purchase Right a notice in compliance with the contractual provisions applicable to such Preferential Purchase Right.

(i) If, prior to Closing, any holder of a Preferential Purchase Right notifies CONSOL that it intends to consummate the acquisition of the Conveyed Interest to which its Preferential Purchase Right applies or if the time for exercising such Preferential Purchase Right has not expired, then the Conveyed Interest subject to such Preferential Purchase Right shall be excluded from the Conveyed Interests to be assigned to Noble at Closing (but only to the extent of the portion of such Conveyed Interest affected by the Preferential Purchase Right), and the Closing Cash Payment shall be reduced by the Allocated Value of such Conveyed Interest (or portion thereof) so excluded. CONSOL shall be entitled to all consideration given by any Person exercising a Preferential Purchase Right prior to Closing. If such holder of such Preferential Purchase Right thereafter fails to consummate the acquisition of the Conveyed Interest (or portion thereof) covered by such Preferential Purchase Right on or before 90 days following the Closing Date or the time for exercising such Preferential Purchase Right expires without exercise by the holder thereof (A) CONSOL shall so notify Noble and (B) CONSOL shall assign, on the tenth Business Day following receipt of such notice or termination of such right without exercise, such Conveyed Interest (or portion thereof) that was so excluded to Noble effective as of the

Effective Time pursuant to an instrument in substantially the same form as the Assignment, and Noble shall pay into a Tax Partnership Account designated by CONSOL the amount by which the Closing Cash Payment was reduced at Closing with respect to such excluded Conveyed Interest (or portion thereof) (as adjusted pursuant to Section 3.2 through the date of such conveyance); and

(ii) All Conveyed Interests for which any applicable Preferential Purchase Right has been waived, or as to which the period to exercise the applicable Preferential Purchase Right has expired (and such Preferential Purchase Right has not been exercised), in each case, prior to Closing, shall be sold to Noble at Closing pursuant to the provisions of this Agreement.

(b) With respect to each Consent set forth in Schedule 7.4 (subject to the provisions of (x) Schedule 9.12(a) with respect to the Processing Contracts and (y) Schedule 9.12(c) with respect to the Gathering Contracts), CONSOL, prior to Closing, shall send to the holder of each such Consent a notice in compliance with the contractual provisions applicable to such Consent seeking such holder’s consent to the transactions contemplated hereby.

(i) If (A) CONSOL fails to obtain a Consent set forth in Schedule 7.4 prior to Closing and the failure to obtain such Consent would cause (1) the assignment of the Conveyed Interests affected thereby to Noble to be void or (2) the termination of a Lease under the express terms thereof, (B) a Consent requested by CONSOL is denied in writing, or (C) the Consent is required from a Governmental Authority (other than a Customary Post Closing Consent), then, in each case, (x) the Conveyed Interest (or portion thereof) affected by such un-obtained Consent shall be excluded from the Conveyed Interests to be assigned to Noble at Closing, and the Closing Cash Payment shall be reduced by the Allocated Value of such Conveyed Interest (or portion thereof) so excluded. In the event that any such Consent (with respect to a Conveyed Interest excluded pursuant to this Section 5.5(b)(i)) that was not obtained prior to Closing is obtained within one year following the Closing Date, then, on the tenth Business Day after such Consent is obtained, CONSOL shall assign the Conveyed Interest (or portion thereof) that was so excluded as a result of such previously un-obtained Consent to Noble pursuant to an instrument in substantially the same form as the Assignment, and Noble shall pay into a Tax Partnership Account designated by CONSOL the amount by which the Closing Cash Payment was reduced at Closing with respect to the Conveyed Interest (or portion thereof) so excluded (as adjusted pursuant to Section 3.2 through the date of such conveyance);

(ii) If CONSOL fails to obtain a Consent set forth in Schedule 7.4 prior to Closing (A) and the failure to obtain such Consent would not cause (1) the assignment of the Conveyed Interest (or portion thereof) affected thereby to Noble to be void or (2) the termination of a Lease under the express terms thereof, (B) such Consent requested by CONSOL is not denied in writing by the holder thereof, and (C) such Consent is not required from a Governmental

Authority (or is a Customary Post Closing Consent), then the Conveyed Interest (or portion thereof) subject to such un-obtained Consent shall nevertheless be assigned by CONSOL to Noble at Closing as part of the Conveyed Interests. Any Liability that arises due to the failure to obtain such Consent shall be borne 50% by CONSOL and 50% by Noble and

(iii) Prior to Closing, CONSOL shall use its commercially reasonable efforts, with reasonable assistance from Noble (including Noble providing requested assurances of financial condition and operator qualifications), to obtain all Consents listed on Schedule 7.4; provided, however, that CONSOL shall not be required to incur any Liability or pay any money in order to obtain any such Consent.

ARTICLE VI

ENVIRONMENTAL MATTERS

6.1 Environmental Defects.

(a) Assertions of Environmental Defects. Noble must deliver claim notices to CONSOL meeting the requirements of this Section 6.1(a) (collectively the “Environmental Defect Notices” and individually an “Environmental Defect Notice”) not later than the Environmental Defect Claim Date setting forth any matters that, in Noble’s reasonable opinion, constitute Environmental Defects and that Noble intends to assert as Environmental Defects pursuant to this Section 6.1. Subject to Noble’s rights under Section 13.2(g) and Section 13.2(h), for all purposes of this Agreement, Noble shall be deemed to have waived, and CONSOL shall have no liability for, any Environmental Defect that Noble fails to assert as an Environmental Defect by a properly delivered Environmental Defect Notice received by CONSOL on or before the Environmental Defect Claim Date. To be effective, each Environmental Defect Notice shall be in writing and shall include (i) a description of the matter constituting the alleged Environmental Defect (including the applicable Environmental Law violated or implicated thereby), (ii) a description of each Conveyed Interest (or portion thereof) that is affected by the alleged Environmental Defect, (iii) Noble’s assertion of the Allocated Value of the portion of the Conveyed Interests affected by the alleged Environmental Defect, (iv) supporting documents reasonably necessary for CONSOL to verify the existence of the alleged Environmental Defect, and (v) a calculation of the Remediation Amount (itemized in reasonable detail) that Noble asserts is attributable to such alleged Environmental Defect. Noble’s calculation of the Remediation Amount included in the Environmental Defect Notice must describe in reasonable detail the Remediation proposed for the Environmental Condition that gives rise to the asserted Environmental Defect and reasonably identify the assumptions used by Noble in calculating the Remediation Amount, including the standards that Noble asserts must be met to comply with Environmental Laws. CONSOL shall have the right, but not the obligation, to attempt, at CONSOL’s sole cost, to cure any claimed Environmental Defect on or before Closing.

(b) Remedies for Environmental Defects. Subject to (x) CONSOL’s continuing right to dispute the existence of an Environmental Defect and/or the Remediation Amount asserted with respect thereto, (y) the rights of the Parties pursuant to Section 14.1(c), and (z) the Individual Environmental Threshold and the Environmental Defect Deductible, in the event that any Environmental Defect timely asserted by Noble in accordance with Section 6.1(a) is not waived in writing by Noble or cured before Closing, CONSOL shall, at its sole option, elect to:

(i) reduce the Closing Cash Payment by the Remediation Amount;

(ii) assume responsibility for the Remediation of such Environmental Defect and CONSOL shall assume and Indemnify Noble for Liability incurred by Noble resulting from such Environmental Defect or the Remediation of such Environmental Defect; or

(iii) upon obtaining Noble’s prior written consent, assume and Indemnify Noble against all Liability resulting from such Environmental Defect with respect to the Conveyed Interests pursuant to an indemnity agreement prepared by CONSOL in a form and substance reasonably acceptable to Noble (each, an “Environmental Indemnity Agreement”).

If CONSOL elects the option set forth in clause (i) above, Noble shall be deemed to have assumed responsibility for all costs and expenses attributable to the Remediation of the applicable Environmental Defect and all Liabilities (net to the Conveyed Interests) with respect thereto and Noble’s obligations with respect to the foregoing shall be deemed to constitute Assumed Obligations. If CONSOL elects the option set forth in clause (ii) above, CONSOL shall use reasonable efforts to implement such Remediation in a manner which is consistent with the requirements of Environmental Laws in a timely fashion for the type of Remediation that CONSOL elects to undertake, and Noble, effective as of the Closing, to the extent necessary, hereby grants to CONSOL and its representatives access to the Conveyed Interests to conduct such Remediation. CONSOL will be deemed to have adequately completed the Remediation required in the immediately preceding sentence (1) upon receipt of a certificate or approval from the applicable Governmental Authority that the Remediation has been implemented to the extent necessary to comply with existing Laws or (2) upon receipt of a certificate from a licensed Third Party professional engineer approved by both Parties that the Remediation has been implemented to the extent necessary to comply with existing Laws, if the certificate or approval from the Government Authority is not applicable.

(c) Exclusive Remedy. Subject to either Party’s right to terminate this Agreement pursuant to Section 14.1(c) and the rights of Noble (i) under Section 13.2(g) and Section 13.2(h) and (ii) for any breach of Section 7.19 by CONSOL, Section 6.1(b) shall be the exclusive right and remedy of Noble with respect to any Environmental Defect or other environmental matter.

(d) Environmental Deductibles. Notwithstanding anything to the contrary, (i) in no event shall there be any adjustments to the Closing Cash Payment or any other remedy provided by CONSOL hereunder for any individual Environmental Defect for

which the Remediation Amount does not exceed $100,000 (the “Individual Environmental Threshold”); and (ii) in no event shall there be any adjustments to the Closing Cash Payment or any other remedy provided by CONSOL hereunder for any Environmental Defect for which the Remediation Amount exceeds the Individual Environmental Threshold unless (A) the sum of the Remediation Amounts of all such Environmental Defects that exceed the Individual Environmental Threshold, in the aggregate (excluding any Remediation Amounts attributable to Conveyed Interests subject to Environmental Defects cured by CONSOL or for which CONSOL provides an Environmental Indemnity Agreement pursuant to Section 6.1(b)(iii)) exceeds (B) the Environmental Defect Deductible, after which point Noble shall be entitled to remedies for such Environmental Defect only to the extent that the Remediation Amounts with respect thereto are in excess of the Environmental Defect Deductible. For the avoidance of doubt, if CONSOL elects pursuant to Section 6.1(b)(iii) to Indemnify Noble with respect to any Environmental Defect, then, after such election, the Remediation Amounts for such Environmental Defect (x) will not be counted towards the Environmental Defect Deductible, and (y) will be counted for purposes of Section 14.1(c).

(e) Environmental Dispute Resolution. CONSOL and Noble shall attempt to agree on all Environmental Defects and Remediation Amounts (collectively, the “Environmental Disputes”) prior to Closing. If CONSOL and Noble are unable to agree upon any Environmental Dispute by Closing, then either Party shall have the right to elect, upon written notice to the other Party, to initiate arbitration to resolve such Environmental Dispute. All Environmental Disputes shall be exclusively and finally resolve such Environmental Dispute through arbitration pursuant to this Section 6.1(e). There shall be a single arbitrator, who shall be an environmental attorney with at least ten years experience in environmental matters involving oil and gas producing properties in the regional area in which the affected Conveyed Interests are located (the “Environmental Arbitrator”). The Environmental Arbitrator shall be selected by mutual agreement of Noble and CONSOL within 15 days after the election by a Party to utilize the provisions of this Section 6.1(e) with respect to an Environmental Dispute. If the Parties are unable to mutually agree upon the Environmental Arbitrator, the Pittsburgh, Pennsylvania office of the AAA shall appoint such Environmental Arbitrator under such conditions as the AAA in its sole discretion deems necessary or advisable. The place of arbitration shall be Pittsburgh, Pennsylvania, and the arbitration shall be conducted in accordance with the AAA Rules, to the extent such rules do not conflict with the terms of this Section 6.1(e). The Environmental Arbitrator’s determination shall be made within 30 days after submission of the Environmental Disputes and shall be final and binding upon both Parties, without right of appeal. In making his determination, the Environmental Arbitrator shall be bound by the rules set forth in this Section 6.1 and, subject to the foregoing, may consider such other matters as in the opinion of the Environmental Arbitrator are necessary to make a proper determination. The Environmental Arbitrator, however, may not award Noble a greater Remediation Amount than the Remediation Amount claimed by Noble in its applicable Environmental Defect Notice. The Environmental Arbitrator shall act for the limited purpose of determining the specific Environmental Disputes submitted by either Party and may not award damages, interest or penalties to either Party with respect to any Environmental Dispute. CONSOL and Noble shall each bear its own legal fees and other costs of presenting its case to the

Environmental Arbitrator. Each of CONSOL and Noble shall bear one-half of the costs and expenses of the Environmental Arbitrator. To the extent that the award of the Environmental Arbitrator with respect to any Remediation Amount is not taken into account as an adjustment to the Closing Cash Payment pursuant to Section 3.4 or Section 3.5, and the applicable Party would otherwise be entitled to an adjustment under the provisions of Section 6.1(d), then within ten days after the Environmental Arbitrator delivers written notice to Noble and CONSOL of his award with respect to a Remediation Amount, and subject to Section 6.1(d), (i) the Carried Cost Obligation shall be increased by the amount so awarded by the Environmental Arbitrator to CONSOL and (ii) the Carried Cost Obligation shall be decreased by the amount so awarded by the Environmental Arbitrator to Noble. Nothing herein shall operate to cause Closing to be delayed on account of any arbitration conducted pursuant to this Section 6.1(e), and to the extent any adjustments are not agreed upon by the Parties as of the Closing, the Closing Cash Payment shall not be adjusted therefor at Closing and subsequent adjustments to the Carried Cost Obligation, if any, will be made pursuant to this Section 6.1(e).

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

(ii) enter into an Applicable Contract that if entered into on or prior to the date of this Agreement, would be required to be listed on Schedule 7.8(a);

(vi) voluntarily relinquish its position as operator with respect to any Conveyed Interest that CONSOL operated as of (A) the date of this Agreement, or (B) the Closing Date; or

(vii) commit to do any of the foregoing.

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

Noble and CONSOL shall cooperate with each other and, subject to the terms of the Confidentiality Agreement, shall promptly furnish all information to the other Party that is necessary in connection with Noble’s and CONSOL’s compliance with the HSR Act. Noble and CONSOL shall keep each other fully advised with respect to any requests from or communications with the DOJ or FTC concerning such filings and shall consult with each other with respect to all responses thereto.

The material terms of the Contribution Agreement, the limited liability company agreement of the Gathering Company and the gathering agreements pursuant to which the Gathering Company will provide gathering services to the Parties (collectively, the “Gathering JV Agreements”) are more particularly described in the Gathering Term Sheet. In the event that the Parties are unable to agree upon the final forms of the Gathering JV Agreements on or prior to the Targeted Closing Date, the provisions of Schedule 9.6 shall be applicable.

In the event that the claim for indemnification is based upon a claim by a Third Party against the Indemnified Party (a “Third Party Claim”), the Indemnified Party shall provide its Claim Notice promptly after the Indemnified Party has actual knowledge of the Third Party Claim and shall enclose a copy of all papers (if any) served with respect to the Third Party Claim; provided that the failure of any Indemnified Party to give notice of a Third Party Claim as provided in this Section 13.7 shall not relieve the Indemnifying Party of its obligations under Sections 4.1(c), 13.2 or 13.3 (as applicable) except to the extent such failure results in insufficient time being available to permit the Indemnifying Party to effectively defend against the Third Party Claim or otherwise materially prejudices the Indemnifying Party’s ability to defend against the Third Party Claim. In the event that the claim for indemnification is based upon an inaccuracy or breach of a representation, warranty, covenant or agreement, the Claim Notice shall specify the representation, warranty, covenant or agreement that was inaccurate or breached.

(c) In the case of a claim for indemnification based upon a Third Party Claim, the Indemnifying Party shall have 30 days from its receipt of the Claim Notice to notify the Indemnified Party whether it admits or denies its liability to defend the Indemnified Party against such Third Party Claim at the sole cost and expense of the Indemnifying Party. The Indemnified Party is authorized, prior to and during such 30 day period, at the expense of the Indemnifying Party, to file any motion, answer or other pleading that it shall deem necessary or appropriate to protect its interests or those of the Indemnifying Party and that is not prejudicial to the Indemnifying Party.

(d) If the Indemnifying Party admits its liability to defend the Indemnified Party against a Third Party Claim, it shall have the right and obligation to diligently defend, at its sole cost and expense, such Third Party Claim. The Indemnifying Party shall have full control of such defense and proceedings, including any compromise or settlement thereof. If requested by the Indemnifying Party, the Indemnified Party agrees to cooperate in contesting any Third Party Claim which the Indemnifying Party elects to contest. The Indemnified Party may participate in, but not control, at its own expense, any defense or settlement of any Third Party Claim controlled by the Indemnifying Party pursuant to this Section 13.7(d). An Indemnifying Party shall not, without the written consent of the Indemnified Party, (i) settle any Third Party Claim or consent to the entry of any judgment with respect thereto which does not include an unconditional written release of the Indemnified Party from all Liability in respect of such Third Party Claim or (ii) settle any Third Party Claim or consent to the entry of any judgment with respect thereto in any manner that may materially and adversely affect the Indemnified Party (other than as a result of money damages covered by the indemnity).

(e) If the Indemnifying Party does not admit its liability or admits its liability to defend the Indemnified Party against the Third Party Claim, but fails to diligently prosecute or settle such Third Party Claim, then the Indemnified Party shall have the right to defend against the Third Party Claim at the sole cost and expense of the Indemnifying

Party, with counsel of the Indemnified Party’s choosing, subject to the right of the Indemnifying Party to admit its liability and assume the defense of the Third Party Claim at any time prior to settlement or final determination thereof. If the Indemnifying Party has not yet admitted its liability to defend the Indemnified Party against the Third Party Claim, the Indemnified Party shall send written notice to the Indemnifying Party of any proposed settlement and the Indemnifying Party shall have the option for ten days following receipt of such notice to (i) admit in writing its liability to indemnify the Indemnified Party from and against the liability and consent to such settlement, (ii) if liability is so admitted, reject, in its reasonable judgment, the proposed settlement, or (iii) deny liability. Any failure to respond to such notice by the Indemnified Party shall be deemed to be an election under subsection (i) above.

(f) In the case of a claim for indemnification not based upon a Third Party Claim, the Indemnifying Party shall have 30 days from its receipt of the Claim Notice to (i) cure the Liabilities complained of, (ii) admit its liability for such Liability or (iii) dispute the claim for such Liabilities. If the Indemnifying Party does not notify the Indemnified Party within such 30 day period that it has cured the Liabilities or that it disputes the claim for such Liabilities, the amount of such Liabilities shall conclusively be deemed a liability of the Indemnifying Party hereunder.

13.8 Survival.

(a) The representations and warranties of CONSOL in Article VII (other than the Fundamental Representations) and the covenants and agreements of CONSOL in Sections 9.1 and 12.4 shall, in each case, survive the Closing for a period of 12 months after the Closing Date; provided, however, (i) the Fundamental Representations of CONSOL shall survive the Closing indefinitely, and (ii) the special warranty of title contained in the Assignment shall survive the Closing without time limitation. Subject to the foregoing and as set forth in Section 13.8(b), the remainder of this Agreement shall survive the Closing without time limit. Any reference to a representation or warranty in this Section 13.8(a) shall also be deemed to include a reference to the corresponding representations and warranties given in any certificate delivered at Closing by either Party. Representations, warranties, covenants and agreements shall be of no further force and effect after the date of their expiration, provided that there shall be no termination of any bona fide claim asserted pursuant to this Agreement with respect to such a representation, warranty, covenant or agreement prior to its expiration date.

(b) The indemnities in Sections 13.2(a), 13.2(b), 13.3(a) and 13.3(b) shall terminate as of the termination date of each respective representation, warranty, covenant or agreement that is subject to indemnification. Noble’s indemnities set forth in Section 4.1(c) and Section 13.3(c) shall survive the Closing without time limit. CONSOL’s indemnities set forth in (i) Sections 13.2(c), 13.2(d) and 13.2(i) shall survive the Closing without time limit, (ii) Section 13.2(f) shall survive the Closing for a period of one year, (iii) Sections 13.2(e) and 13.2(j) shall survive the Closing for a period of two years, (iv) Section 13.2(g) shall survive the Closing for a period of five years, and (v) Section 13.2(h) shall survive the Closing for a period of five years. Notwithstanding the foregoing, there shall be no termination of any bona fide claim asserted pursuant to the indemnities in Sections 13.2(a) through 13.2(j) or Sections 13.3(a) through 13.3(c), if such bona fide claim is asserted prior to the date of termination for the applicable indemnity.

13.9 Non-Compensatory Damages. None of the Noble Indemnified Parties nor CONSOL Indemnified Parties shall be entitled to recover from CONSOL or Noble, or their respective Affiliates, any indirect, special, incidental, consequential, punitive, exemplary, remote or speculative damages or damages for lost profits of any kind arising under or in connection with this Agreement or the transactions contemplated hereby, except to the extent any such Party suffers such damages to a Third Party, which damages (including costs of defense and reasonable attorneys’ fees incurred in connection with defending against such damages) shall not be excluded by this provision as to recovery hereunder. Subject to the preceding sentence, Noble, on behalf of each of the Noble Indemnified Parties, and CONSOL, on behalf of each of CONSOL Indemnified Parties, waive any right to recover punitive, special, indirect, exemplary, consequential damages, remote or speculative, including damages for lost profits of any kind, arising in connection with or with respect to this Agreement or the transactions contemplated hereby.

13.10 Cooperation by Noble Concerning Retained Litigation. Noble agrees to use reasonable efforts to cooperate with CONSOL in connection with CONSOL’s defense and other actions relating to or arising out of the litigation and claims set forth on Schedule 7.7.

13.11 Waiver of Right to Rescission. CONSOL and Noble acknowledge that, following Closing, the payment of money, as limited by the terms of this Agreement, shall be adequate compensation for breach of any representation, warranty, covenant or agreement contained herein or for any other claim arising in connection with or with respect to the transactions contemplated by this Agreement. As the payment of money shall be adequate compensation, following Closing, Noble and CONSOL waive any right to rescind this Agreement or any of the transactions contemplated hereby.

13.12 Insurance. The amount of any Liabilities for which any of the Noble Indemnified Parties is entitled to indemnification under this Agreement or in connection with or with respect to the transactions contemplated by this Agreement shall be reduced by any corresponding insurance proceeds, from insurance policies carried by a Party, that are actually realized by such Party or that could reasonably be expected to be realized by such Party if a claim were properly pursued under the relevant insurance arrangements.

13.13 Materiality. For purposes of this Article XIII, any Liability resulting from any breach or inaccuracy in the representations and warranties under this Agreement and the corresponding representations and warranties given in the certificates to be delivered by CONSOL at Closing pursuant to Section 10.5 shall be determined without regard to any materiality qualifiers in or affecting such representations or warranties.

ARTICLE XIV

TERMINATION, DEFAULT AND REMEDIES

14.1 Right of Termination. This Agreement and the transactions contemplated herein may be terminated at any time at or prior to Closing:

(a) by CONSOL, at CONSOL’s option, if any of the conditions set forth in Article XI (other than the conditions set forth in Section 11.3, Section 11.4, Section 11.5, Section 11.6 and Section 11.8) have not been satisfied (or waived by CONSOL) on or before the Outside Termination Date (as such date may be extended by Noble pursuant to the terms hereof);

(b) by Noble, at Noble’s option, if any of the conditions set forth in Article X (other than the conditions set forth in Section 10.3, Section 10.4, Section 10.5 and Section 10.6) have not been satisfied (or waived by Noble) on or before the Outside Termination Date (as such date may be extended by Noble pursuant to the terms hereof);

(c) by either Party if any of the conditions set forth in Section 10.3, Section 10.4, Section 10.5, Section 10.6, Section 11.3, Section 11.4, Section 11.5 or Section 11.6 have not been satisfied (or waived by (i) CONSOL with respect to the conditions set forth in Section 10.3, Section 10.4, Section 10.5 and Section 10.6 or (ii) Noble with respect to the conditions set forth in Section 11.3, Section 11.4, Section 11.5 and Section 11.6) on or before the Outside Termination Date (as such date may be extended by Noble pursuant to the terms hereof);

(d) by CONSOL, at CONSOL’s option, if the condition set forth in Section 11.8 has not been satisfied (or waived by CONSOL) on or before the Outside Termination Date (as such date may be extended by Noble pursuant to the terms hereof);

(e) by either Party, at such Party’s option, at any time following ten days after the Outside Termination Date (as such date may be extended by Noble pursuant to the terms hereof); or

(f) by the mutual written agreement of CONSOL and Noble;

provided, however, that no Party shall have the right to terminate this Agreement pursuant to subsections (a), (b), (c) or (d) above if such Party or its Affiliates are at such time in material breach of any provision of this Agreement.

14.2 Effect of Termination.

(a) If the obligation to close the transactions contemplated by this Agreement is terminated pursuant to any provision of Section 14.1 hereof, then, except for the provisions of Article I, Sections 4.1(c) through 4.1(e), 4.2, 4.3, 13.9, this Section 14.2, Article XV (other than Sections 15.2(b) through 15.2(e), 15.3, 15.4, 15.10 and 15.11) and such of the defined terms in Appendix I necessary to give context to the surviving provisions, this Agreement shall forthwith become void and the Parties shall have no liability or obligation hereunder.

(b) If this Agreement is terminated by CONSOL pursuant to Section 14.1(a) because of (i) the Willful Breach by Noble of this Agreement, or (ii) the failure of Noble to close in the instance where, as of the Outside Termination Date (as such date may be extended by Noble pursuant to the terms hereof), (A) all of the conditions in Article X (excluding conditions that, by their terms, cannot be satisfied until

the Closing) have been satisfied (or waived by Noble), (B) CONSOL is ready, willing and able to perform its obligations under Section 12.3, and (C) Noble nevertheless elects not to close, then in either such event, the Parties agree and acknowledge that CONSOL will suffer damages that are not practicable to ascertain. Accordingly, after such termination of this Agreement by CONSOL, CONSOL shall be entitled to an amount equal to $100,000,000 as liquidated damages, which amount shall be immediately payable by wire transfer in immediately available funds by Noble to CONSOL. The Parties agree that the foregoing liquidated damages are reasonable considering all of the circumstances existing as of the date hereof and constitute the Parties’ good faith estimate of the actual damages reasonably expected to result from such termination of this Agreement by CONSOL. CONSOL agrees that, to the fullest extent permitted by Law, CONSOL’s right to payment of such liquidated damages as provided in this Section 14.2(b) shall be its sole and exclusive remedy if the Closing does not occur with respect to any Liabilities whatsoever that CONSOL may suffer or allege to suffer as a result of the termination of this Agreement pursuant to Section 14.1(a).

(c) If this Agreement is terminated by Noble pursuant to Section 14.1(b) because of (i) the Willful Breach by CONSOL of this Agreement, or (ii) the failure of CONSOL to close in the instance where, as of the Outside Termination Date (as such date may be extended by Noble pursuant to the terms hereof), (A) all of the conditions in Article XI (excluding conditions that, by their terms, cannot be satisfied until the Closing) have been satisfied (or waived by CONSOL), (B) Noble is ready, willing and able to perform its obligations under Section 12.3, and (C) CONSOL nevertheless elects not to close, then in either such event, the Parties agree and acknowledge that Noble will suffer damages that are not practicable to ascertain. Accordingly, after such termination of this Agreement by Noble, Noble shall be entitled to an amount equal to $100,000,000 as liquidated damages, which amount shall be immediately payable by wire transfer in immediately available funds by CONSOL to Noble. The Parties agree that the foregoing liquidated damages are reasonable considering all of the circumstances existing as of the date hereof and constitute the Parties’ good faith estimate of the actual damages reasonably expected to result from such termination of this Agreement by Noble. Noble agrees that, to the fullest extent permitted by Law, Noble’s right to payment of such liquidated damages as provided in this Section 14.2(c) shall be its sole and exclusive remedy if the Closing does not occur with respect to any Liabilities whatsoever that Noble may suffer or allege to suffer as a result of the termination of this Agreement pursuant to Section 14.1(b).

(d) Subject to the foregoing, upon the termination of this Agreement neither Party has any other liability or obligation hereunder.

14.3 Return of Documentation and Confidentiality. Upon termination of this Agreement, Noble shall return to CONSOL or shall destroy all title, engineering, geological and geophysical data, environmental assessments and/or reports, maps and other information furnished by CONSOL to Noble or prepared by or on behalf of Noble in connection with its due diligence investigation of the Conveyed Interests, in each case, in accordance with the Confidentiality Agreement (and subject to such retention rights as are provided in the Confidentiality Agreement) and an officer of Noble shall certify same to CONSOL in writing.

ARTICLE XV

MISCELLANEOUS

15.1 Appendices, Exhibits and Schedules. All of the Appendices, Exhibits and Schedules referred to in this Agreement are hereby incorporated into this Agreement by reference and constitute a part of this Agreement. Each Party to this Agreement and its counsel has received a complete set of Appendices, Exhibits and Schedules prior to and as of the execution of this Agreement.

15.2 Expenses and Taxes.

(a) Except as otherwise specifically provided, all fees, costs and expenses incurred by the Parties in negotiating this Agreement or in consummating the transactions contemplated by this Agreement shall be paid by the Party incurring the same, including legal and accounting fees, costs and expenses.

(b) All required documentary, filing and recording fees and expenses in connection with the filing and recording of the assignments, conveyances or other instruments required to convey title to the Conveyed Interests shall be borne by Noble.

(c) CONSOL shall retain responsibility for, and shall bear and pay, (i) all federal income Taxes, state income Taxes, and other similar Taxes (including any applicable interest or penalties) incurred or imposed with respect to the transactions described in this Agreement, (ii) 50% of all Transfer Taxes incurred or imposed with respect to the transfer to Noble of the Conveyed Interests and (iii) 100% of the Transfer Taxes, if any, incurred with respect to the Oil and Gas Assets other than the Conveyed Interests. Noble shall assume responsibility for, and shall bear and pay, 50% of all Transfer Taxes incurred or imposed with respect to the transfer to Noble of the Conveyed Interests. The Parties will cooperate in establishing the applicability of any occasional sale or other exemption from Transfer Taxes that may be applicable to the transfer to Noble of the Conveyed Interests.

(d) CONSOL shall retain responsibility for, and shall bear and pay, all Asset Taxes assessed with respect to the ownership and operation of the Conveyed Interests for (i) any period ending prior to the Effective Time and (ii) the portion of any Straddle Period ending immediately prior to the Effective Time. All Asset Taxes with respect to the ownership or operation of the Conveyed Interests arising on or after the Effective Time (including all Straddle Period Taxes not apportioned to CONSOL) shall be allocated to and borne by Noble. For purposes of allocation between the Parties of Asset Taxes that are payable with respect to Straddle Periods, the portion of any such Taxes that are attributable to the portion of the Straddle Period that ends immediately prior to the Effective Time shall (A) in the case of Asset Taxes that are based upon or related to revenues, income or receipts or imposed on a transactional basis such as severance or production Taxes, be allocated based on revenues from sales occurring before the Effective Time (which shall be CONSOL’s responsibility) and from and after the Effective Time (which shall be Noble’s responsibility); and (B) in the case of other Asset Taxes, be allocated pro rata per day between the period immediately prior to the Effective

Time and the period beginning on the Effective Time. For purposes of clause (A) of the preceding sentence, any exemption, deduction, credit or other item that is calculated on an annual basis shall be allocated pro rata per day between the period ending immediately prior to the Effective Time and the period beginning on the Effective Time. To the extent the actual amount of Asset Taxes is not determinable at Closing, Noble and CONSOL shall utilize the most recent information available in estimating the amount of Asset Taxes for purposes of Sections 3.2(a)(iv) and 3.2(b)(v). Upon determination of the actual amount of Asset Taxes, CONSOL shall pay to Noble to the extent not taken into account in the Final Settlement Statement any additional amount necessary to equal CONSOL’s share of the Asset Taxes. In the event the amount of Asset Taxes paid by CONSOL or included as a reduction to the Closing Cash Payment pursuant to Section 3.2(b)(v) at Closing exceeds CONSOL’s share of Asset Taxes, Noble shall pay the amount of any such overage to CONSOL. Any allocation of Asset Taxes between the Parties shall be in accordance with this Section 15.2(d).

(e) CONSOL shall prepare and file all Tax Returns with respect to Asset Taxes that are due on or prior to the Closing Date and, subject to the provisions of Sections 3.2(a)(iv), 3.2(b)(v) and 15.2 and Section 4(f) of the Services Agreement, pay all Asset Taxes shown to be due thereon. With respect to Asset Taxes that are due after the Closing Date, each Party shall, subject to the provisions of Sections 3.2(a)(iv), 3.2(b)(v) and 15.2 and Section 4(f) of the Services Agreement, (i) pay (or cause to be paid) all such Asset Taxes for which such Party is responsible and (ii) prepare and file (or cause to be prepared and filed) all such Tax Returns for which such Party is responsible. The Parties acknowledge that, to the extent any Party Operator (as defined in the Development Agreement) pays any such Asset Taxes on behalf of the non-operators under any Applicable Operating Agreement (as defined in the Development Agreement), such Asset Taxes shall be chargeable to the joint account and billable to the parties to such Applicable Operating Agreement pursuant to the terms of such Applicable Operating Agreement.

15.3 Tax Treatment. The Parties intend and expect that the transactions contemplated by this Agreement, the Development Agreement and the Transaction Documents, taken together, will be treated, for purposes of federal income taxation and for purposes of certain state income Tax Laws that incorporate or follow federal income tax principles (“Tax Purposes”), as resulting in the creation of a partnership (the “Tax Partnership”) in which Noble and CONSOL are treated as partners. Accordingly, for Tax Purposes (a) the Tax Partnership will be treated from and after Closing as (i) holding (A) 100% of the Parties’ interests in the Oil and Gas Assets, (B) any other Subject Assets acquired by the Parties jointly pursuant to the Development Agreement, and (C) any cash held in any Tax Partnership Account and (ii) engaging in all activities of the Parties with respect to the aforementioned assets; (b) CONSOL will be treated as contributing to the Tax Partnership at Closing all of its interests in the Oil and Gas Assets and providing its undertaking to fund, when due, the costs and expenses allocable to it under the Development Agreement in exchange for an interest in the Tax Partnership; (c) Noble will be treated as contributing to the Tax Partnership at Closing (by deposit into the Cost Reconciliation Account) the Closing Cash Payment (as adjusted) and providing its undertaking to fund, when due the Post Closing Cash Payments and the costs and expenses allocable to it under the Development Agreement (including the Carried Cost Obligation) in exchange for an interest in

the Tax Partnership; (d) upon any withdrawal by CONSOL (as and to the extent permitted by the Development Agreement) of the Total Cost Sharing Payments from the Cost Reconciliation Account, CONSOL will be treated as receiving a distribution from the Tax Partnership of the withdrawn amount (i) as a reimbursement of CONSOL’s preformation expenditures with respect to the Oil and Gas Assets within the meaning of Treasury Regulations Section 1.707-4(d) to the extent applicable and (ii) in a transaction subject to treatment under Section 707(a) of the Code and its implementing Treasury Regulations as in part a sale, and in part a contribution, of the Oil and Gas Assets to the Tax Partnership to the extent that Treasury Regulations Section 1.707-4(d) is inapplicable, and (e) from and after its commencement, the Tax Partnership will be treated as realizing all items of income or gain and incurring all items of cost or expense attributable to the ownership, operation or disposition of the Subject Assets, notwithstanding that such items are realized, paid or incurred by the Parties individually. The governing terms and conditions of the Tax Partnership (the “Tax Partnership Agreement”) are set forth in the form thereof to be executed at Closing, attached as Exhibit D hereto.

15.4 Value Allocations for Tax Purposes. CONSOL and Noble agree that the portion, if any, of the Total Cost Sharing Payments and the Assumed Obligations that could be treated for federal tax purposes as consideration for a sale transaction (collectively, the “Allocable Amount”) shall be allocated among the various Conveyed Interests for federal and state income tax purposes. The initial draft of such allocations shall be prepared in a manner consistent with the Allocated Values by CONSOL in a manner consistent with Sections 3.7 and 15.3 and shall be provided to Noble concurrently with the delivery of the Final Settlement Statement. CONSOL and Noble shall then cooperate to prepare a final Schedule of any Allocable Amount among the Conveyed Interests, which shall also be materially consistent with the Allocated Values (as adjusted, the “Allocation Schedule”). The Allocation Schedule shall be updated to reflect any adjustments to Allocable Amount. If agreed by the Parties, the allocation of the Allocable Amount shall be reflected on a completed Internal Revenue Service Form 8594 (Asset Acquisition Statement under Section 1060), which Form will be timely filed separately by CONSOL and Noble (and/or the Tax Partnership, as appropriate) with the Internal Revenue Service pursuant to the requirements of Section 1060(b) of the Code. Each Party agrees not to (and to cause the Tax Partnership not to) take any position inconsistent with this Section 15.4 or the allocations set forth in the Allocation Schedule unless required by applicable Law or with the consent of the other Party. The Parties further agree that the allocations set forth on the Allocation Schedule will represent reasonable estimates of the fair market values of the Conveyed Interests described therein.

15.5 Dispute Resolution. The procedures of Section 3.6 shall be applied in the event of a dispute for any item under Sections 15.2, 15.3 or 15.4.

15.6 Assignment. This Agreement may not be assigned by either Party without the prior written consent of the other Party. No assignment of any rights hereunder by either Party shall relieve such Party of any obligations (including indemnity obligations) and responsibilities hereunder.

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

15.8 Publicity. CONSOL and Noble shall consult with each other with regard to all press releases or other public or private announcements issued or made at or prior to the Closing concerning this Agreement or the transactions contemplated herein, and, except as may be required by applicable Laws or the applicable rules and regulations of any Governmental Authority or stock exchange, neither Noble nor CONSOL shall issue any such press release or other publicity without the prior written consent of the other Party, which shall not be unreasonably withheld. The Parties shall be obligated to hold all specific terms and provisions of this Agreement strictly confidential until the expiration of two years after the Closing under this Agreement; provided, however, that the foregoing shall not (a) restrict disclosures by Noble or CONSOL that are required by applicable securities or other Laws or regulations or the applicable rules of any stock exchange having jurisdiction over the disclosing Party or its Affiliates, (b) prevent Noble or CONSOL from recording the Assignment and any federal or state assignments delivered at Closing or from complying with any disclosure requirements of Governmental Authorities that are applicable to the transfer of the Conveyed Interests from CONSOL to Noble, (c) prevent Noble or CONSOL from making any disclosure of information relating to this Agreement if made in a manner, under conditions and to Persons that would be permitted under the Confidentiality Agreement so long as such Person continue to hold such information confidential on the same terms as set forth in this Section, and (d) prevent CONSOL from making disclosures in connection with complying with Preferential Purchase Rights and other transfer restrictions applicable to the transactions contemplated hereby.

15.9 Notices. All notices and communications required or permitted to be given hereunder, shall be sufficient in all respects if given in writing and delivered personally, or sent by bonded overnight courier, or mailed by U.S. Express Mail or by certified or registered United States Mail with all postage fully prepaid, or sent by facsimile transmission (provided any such facsimile transmission is confirmed either orally or by written confirmation).
