26

production (and accounts receivable with respect thereto), (i) liquid Hydrocarbons are deemed to be “attributable to” the Subject Oil and Gas Interests when they pass through the wellhead into the storage facilities into which they are run and (ii) gaseous Hydrocarbons are deemed to be “attributable to” Subject Oil and Gas Interests when they pass through the delivery point sales meters on the pipelines through which they are transported. Seller may utilize reasonable interpolative procedures to arrive at an allocation of Hydrocarbon production when exact meter readings or gauging and strapping data is not available.

Section 3.4       Spud Fee .

(b)        Buyer acknowledges that the permission of the operator (if other than Seller or its affiliate) or another third Person may be required before Buyer will be able to inspect portions of the Conveyed Properties and that such permission must be obtained prior to the inspection of such portions. Seller shall use commercially reasonable efforts to obtain such permission for Buyer upon Buyer’s request. All investigations and due diligence conducted by Buyer or Buyer’s Representatives shall be conducted at Buyer’s sole cost, risk and expense

48

If Buyer requests authorization to perform any sampling, testing or operation, Seller shall have the right, in its sole discretion, to reject Buyer’s request up to and within forty-eight (48) hours of receipt. However, if Seller rejects Buyer’s request, Buyer shall have the right, in its sole discretion, to exclude the applicable Conveyed Property from the Conveyed Properties conveyed by Seller to Buyer at Closing in which case the Purchase Price shall be reduced by the Allocated Value of such Retained Property.

49

party operator to allow Buyer and Buyer’s Representatives such access, it being understood by Buyer that the execution by Buyer or Buyer’s Representatives of a customary access agreement may be a condition of such access. The Parties agree that all information discovered during Buyer’s Environmental Review shall be governed by the terms of the Confidentiality Agreement.

(b)        BUYER SHALL DEFEND, INDEMNIFY AND HOLD HARMLESS THE SELLER INDEMNIFIED PARTIES, FROM AND AGAINST ANY AND ALL LIABILITIES ARISING OUT OF, RESULTING FROM, BASED ON, ASSOCIATED WITH, OR RELATING TO, IN ANY WAY, THE ACCESS AFFORDED TO BUYER PURSUANT TO THIS ARTICLE VI , REGARDLESS OF WHETHER SUCH LIABILITIES ARISE OUT OF OR RESULT FROM, SOLELY OR IN PART, THE SOLE, ACTIVE, PASSIVE, CONCURRENT OR COMPARATIVE NEGLIGENCE, STRICT LIABILITY OR OTHER FAULT OR VIOLATION OF LAW OF OR BY ANY OF THE SELLER INDEMNIFIED PARTIES, EXCEPTING ONLY (i) LIABILITIES TO THE EXTENT RESULTING FROM THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF ANY OF THE SELLER INDEMNIFIED PARTIES AND (ii) LIABILITIES FOR ENVIRONMENTAL CONDITIONS MERELY DISCOVERED AS A RESULT OF BUYER’S ENVIRONMENTAL REVIEW THAT WERE EXISTING PRIOR TO SUCH ACCESS, WHICH LIABILITIES SHALL BE ALLOCATED PURSUANT TO THE OTHER PROVISIONS OF THIS AGREEMENT.

Section 6.4         Notice of Title Defects and Title Benefits; Remedies .

(a)        If Seller discovers any Title Benefit, or Buyer discovers any Title Defect, then such Party may deliver to the other Party, on or prior to the Defect Deadline, a Title Notice with respect to such Title Benefit or Title Defect, as applicable. Except as set forth in the special warranty of title contained in the Assignment and the Surface Deed, Seller and Buyer shall be deemed to have waived, and neither Buyer nor Seller, respectively, shall have any liability for, any Title Benefit or Title Defect for which Buyer or Seller, respectively, has not received a proper Title Notice on or before the Defect Deadline. For the avoidance of doubt, if Buyer or Seller fails to provide a Title Notice which satisfies the requirements set forth in the definition of Title Notice, then the relevant Title Defect(s) or Title Benefit(s), as the case may be, shall be deemed waived.

(b)        With respect to each Listed Interest for which Buyer has asserted a Title Defect pursuant to a properly and timely delivered Title Notice (each such Listed Interest, a “ Title Defect Property ”), Seller shall have until the third (3rd) day prior to Closing (the “ Defect Response Date ”) to notify Buyer of those asserted Title Defects Seller elects to attempt to cure (each, a “ Title Cure Election ”) and those asserted Title Defects and/or the Title Defect Amounts Seller disputes (each, a “ Title Dispute Election ”). At Closing or upon resolution of a Disputed Title Matter, as applicable, with respect to each Title Defect Property that Seller has not cured (and Buyer has not elected to waive in writing), the following shall apply:

(i)        if the Title Defect Amount is equal to or greater than the Allocated Value of the applicable Title Defect Property, then Seller shall have the option, in its sole discretion, to exclude such Title Defect Property (and all related or associated Conveyed Properties) from the Conveyed Properties conveyed by Seller to Buyer pursuant to this Agreement, in which case, the Purchase Price shall be reduced by the Allocated Value of such Retained Property ( provided , however , any Conveyed Properties owned by Oakfield may not be excluded from the transactions contemplated hereby and clause (ii) below shall apply thereto); or

(ii)        Seller shall include such Title Defect Property (and all related or associated Conveyed Properties) (any such Title Defect Property, together with all other such Title Defect Properties, the “ Included Title Defect Properties ”) in the Conveyed Properties conveyed by Seller to Buyer pursuant to this Agreement, in which case, (A) if Seller has not made a Title Cure Election or Title Dispute Election with respect to such Title Defect Property prior to the Defect Response Date, the Purchase Price payable at Closing shall be reduced by the Title Defect Amount for such Included Title Defect Property (as determined by mutual agreement of the Parties), (B) if Seller has made a Title Cure Election or Title Dispute Election with respect to such Title Defect Property prior to the Defect Response Date, the Purchase Price payable at Closing shall be reduced by the Title Defect Amount for such Included Title Defect Property (as determined by mutual agreement of the Parties or if the Parties cannot agree, by Buyer acting reasonably and in good faith) and at the Closing Buyer shall deposit such amount into the Escrow Account pending the curing or resolution of the applicable Title Defect, or (C)

51

upon resolution of a Disputed Title Matter, the Purchase Price shall be reduced (without duplication) by the Title Defect Amount (if any) for such Included Title Defect Property (as determined by the Arbitrator).

(c)        With respect to any Included Title Defect Property for which there is a timely delivered Title Cure Election or Title Dispute Election, until the one hundred twentieth (120th) day after the Closing (such period, the “ Cure Period ”), Seller may, but shall have no obligation to, at its sole cost and expense, cure the Title Defect asserted with respect to such Included Title Defect Property. If, as of the expiration of the Cure Period, Seller has cured (or partially cured) any Title Defect affecting any Included Title Defect Property, within ten (10) days after the end of the Cure Period, Seller and Buyer shall jointly instruct the Escrow Agent to pay the amounts deposited in escrow in respect of any portion of the Title Defect that was cured to Seller, and pay the amounts deposited in escrow in respect of any portion of the Title Defect that was not cured to Buyer. With respect to any Included Title Defect Property for which there is a timely delivered Title Dispute Election, the provisions of Section  6.7 shall apply and at the resolution of such Disputed Matter pursuant to Section  6.7 , the amount deposited in escrow with respect thereto shall be released from the Escrow Account to Seller or Buyer, as applicable, pursuant to the decision of the Arbitrator.

(d)        Notwithstanding anything to the contrary set forth herein, in no event shall there be any remedies provided by Seller (other than with respect to the special warranty of title provided in the Assignment and the Surface Deed delivered at Closing), and Seller shall not be responsible for nor shall the Purchase Price be reduced for, (i) any individual Title Defect for which the Title Defect Amount does not exceed fifty thousand dollars ($50,000) (the “ Title Threshold ”) or (ii) any Title Defect with respect to which the Title Defect Amount exceeds the applicable Title Threshold, unless and until the aggregate of (1) all such Title Defect Amounts that exceed the applicable Title Threshold (excluding any Title Defect Amounts attributable to Title Defects that are cured by Seller pursuant to Section  6.4(c) and less the aggregate of all Title Benefit Amounts that exceed the Title Threshold) and (2) all such Environmental Defect Amounts that exceed the applicable Environmental Threshold (excluding the amount of Environmental Defect Amounts attributable to Environmental Defects that are cured by Seller pursuant to Section  6.6(b) ), exceeds an amount equal to two percent (2%) of the aggregate of the Allocated Values of all Listed Interests (the “ Defect Deductible ”), and then only with respect to the amount of such Title Defect Amounts (less such Title Benefit Amounts) that exceed the Defect Deductible.

Section 6.5         Title Defect Amount; Title Benefit Amount .

(a)        The amount by which the Allocated Value of any Listed Interest is reduced as a result of the existence of a Title Defect with respect thereto is the “ Title Defect Amount ”, which shall be determined in accordance with the following methodology, terms and conditions:

(i)        if Buyer and Seller agree on the Title Defect Amount, then such amount shall be the Title Defect Amount;

52

(ii)        if the Title Defect is a lien or encumbrance that is undisputed and liquidated in amount, then the Title Defect Amount shall be equal to the amount necessary to be paid to remove such encumbrance from the Listed Interest;

(iii)        if the Title Defect represents a decrease in (A) the actual Net Revenue Interest for any Well, with respect to the Target Depth for such Well, below (B) the Net Revenue Interest stated on Exhibit C for such Well (and there is a corresponding decrease in the Working Interest for such Well below the Working Interest stated on Exhibit C with respect to the Target Depth for such Listed Interest), then the Title Defect Amount shall be the product of (y) the Allocated Value of such Well multiplied by (z) one (1), minus a fraction, the numerator of which is the actual Net Revenue Interest for such Well, with respect to the Target Depth for such Well, and the denominator of which is the Net Revenue Interest for such Well stated on Exhibit  C ;

(iv)        if the Title Defect represents a decrease in (A) the actual Net Revenue Interest for any Undeveloped Lease, with respect to the Target Depth for such Undeveloped Lease, below (B) the Net Revenue Interest Floor (or the Net Revenue Interest set forth on Exhibit  C for such Undeveloped Lease, as the case may be) (and there is a corresponding decrease in the Working Interest for such Undeveloped Lease below the Working Interest stated on Exhibit C with respect to the Target Depth for such Listed Interest), then the Title Defect Amount shall be an amount equal to the product of the Allocated Value of such Undeveloped Lease multiplied by a fraction, the numerator of which is the amount by which the Net Revenue Interest Floor (or the Net Revenue Interest set forth on Exhibit  C for such Undeveloped Lease, as the case may be) exceeds such actual Net Revenue Interest, with respect to the Target Depth for such Undeveloped Lease, and the denominator of which is the Net Revenue Interest Floor (or the Net Revenue Interest set forth on Exhibit  C for such Undeveloped Lease, as the case may be);

(v)        if the Title Defect represents a decrease in (A) the actual Net Mineral Acres covered by an Undeveloped Lease (with respect to the Target Depth for such Undeveloped Lease) below (B) the Net Mineral Acres for such Undeveloped Lease stated on Exhibit C , then the Title Defect Amount shall be the product of (x) the Allocated Value of such Undeveloped Lease multiplied by (y) one (1), minus a fraction, the numerator of which is the actual Net Mineral Acres covered by such Undeveloped Lease (with respect to the Target Depth for such Undeveloped Lease) and the denominator of which is the Net Mineral Acres for such Undeveloped Lease stated on Exhibit C ;

(vi)        if the Title Defect represents an obligation or encumbrance upon, or other defect in title to, a Listed Interest of a type not described above, the Title Defect Amount shall be determined by taking into account the Allocated Value of such Listed Interest, the portion of such Listed Interest affected by the Title Defect, the legal effect of the Title Defect, the potential economic effect of the Title Defect over the life of such Listed Interest, the values placed upon the Title Defect by Buyer and Seller and such other reasonable factors as are necessary to make a proper evaluation;

53

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

(viii)        notwithstanding anything to the contrary set forth herein, the aggregate Title Defect Amounts attributable to the effects of all Title Defects upon any Listed Interest shall not exceed the Allocated Value of such Listed Interest.

(b)        The only remedy for Title Benefits is the netting against Title Defect Amounts pursuant to Section  6.4(d) which is only available for each Title Benefit Amount exceeding the Title Threshold. Each “ Title Benefit Amount ” shall be determined in accordance with the following methodology, terms and conditions:

(i)        if Buyer and Seller agree on the Title Benefit Amount, then such amount shall be the Title Benefit Amount;

(ii)        if the Title Benefit represents an increase in (A) the actual Net Revenue Interest for any Well, with respect to the Target Depth for such Well, over (B) the Net Revenue Interest stated on Exhibit C for such Well (and there is a corresponding increase in the Working Interest for such Well), then the Title Benefit Amount shall be the product of (y) the Allocated Value of such Well multiplied by (z) the result obtained by subtracting one (1) from a fraction, the numerator of which is the actual Net Revenue Interest for such Well, with respect to the Target Depth for such Well, and the denominator of which is the Net Revenue Interest for such Well stated on Exhibit C ;

(iii)        if the Title Benefit represents an increase in (A) the actual Net Mineral Acres covered by an Undeveloped Lease (with respect to the Target Depth for such Undeveloped Lease) above (B) the Net Mineral Acres for such Undeveloped Lease stated on Exhibit C , then the Title Benefit Amount shall be the product of (x) the Allocated Value of such Undeveloped Lease multiplied by (y) the result obtained by subtracting one (1) from a fraction, the numerator of which is the actual Net Mineral Acres covered by such Undeveloped Lease (with respect to the Target Depth for such Undeveloped Lease) and the denominator of which is the Net Mineral Acres for such Undeveloped Lease stated on Exhibit C ; and

(iv)        if the Title Benefit Amount cannot be calculated pursuant to subsections (i), (ii) or (iii) above, then the Title Benefit Amount shall be determined by taking into account the Allocated Value of the Listed Interest, the portion of such Listed Interest affected by the Title Benefit, the legal effect of the Title Benefit, the potential economic effect of the Title Benefit over the life of the Listed Interest, the values placed upon the Title Benefit by Buyer and Seller and such other reasonable factors as are necessary to make a proper evaluation.

Section 6.6         Notice of Environmental Defects ; Remedies .

For the avoidance of doubt, if Buyer

54

fails to provide an Environmental Notice which satisfies the requirements set forth in the definition of Environmental Notice, then the relevant Environmental Defect(s) shall be deemed waived.

(b)        With respect to each Conveyed Property (other than a Buyer Operated Property) for which Buyer has asserted an Environmental Defect pursuant to a properly and timely delivered Environmental Notice (each such Conveyed Property, an “ Environmental Defect Property ”), Seller shall have until the Defect Response Date to notify Buyer of those asserted Environmental Defects Seller elects to attempt to cure (each, an “ Environmental Cure Election ”) and those asserted Environmental Defects Seller disputes (each, an “ Environmental Dispute Election ”). At Closing or upon resolution of a Disputed Environmental Matter, as applicable, with respect to each Environmental Defect Property that Seller has not cured (and Buyer has not elected to waive in writing), the following shall apply:

(i)        if the Environmental Defect Amount is equal to or greater than the greater of (A) Allocated Value of the applicable Environmental Defect Property and (B) one hundred thousand dollars ($100,000), then either Seller or Buyer shall have the option, in its sole discretion, exclude such Environmental Defect Property (and all related or associated Conveyed Properties) from the Conveyed Properties conveyed by Seller to Buyer pursuant to this Agreement, in which case, the Purchase Price shall be reduced by the Allocated Value of such Retained Property ( provided , however , any Conveyed Property owned by Oakfield may not be excluded from the transactions contemplated hereby and clause (ii) below shall apply thereto);

(ii)        Seller shall include such Environmental Defect Property (and all related or associated Conveyed Properties) (any such Environmental Defect Property, together with all other such included Environmental Defect Properties, the “ Included Environmental Defect Properties ”) in the Conveyed Properties conveyed by Seller to Buyer pursuant to this Agreement, in which case, (A) if Seller has not made an Environmental Cure Election or an Environmental Dispute Election with respect to such Environmental Defect Property prior to the Defect Response Date, the Purchase Price payable at Closing shall be reduced by the Environmental Defect Amount for such Included Environmental Defect Property (as determined by mutual agreement of the Parties), (B) if Seller has made an Environmental Dispute Election with respect to such Environmental Defect Property prior to the Defect Response Date, the Purchase Price payable at Closing shall be reduced by the Environmental Defect Amount for such Included Environmental Defect Property (as determined by mutual agreement of the Parties or if the Parties cannot agree, by Buyer acting reasonably and in good faith) and at the Closing Buyer shall deposit such amount into the Escrow Account pending the resolution of the applicable Environmental Defect, or (C) upon resolution of a Disputed Environmental Matter, the Purchase Price shall be reduced by the Environmental Defect Amount for such Included Environmental Defect Property (as determined by the Arbitrator); or

(iii)        if Seller has made an Environmental Cure Election with respect to any Environmental Defect Property prior to the Defect Response Date, such Environmental Defect Property shall be excluded from the Conveyed Properties conveyed by Seller to Buyer at the Closing (each, a “ Subject Environmental Defect Property ”) and the Purchase Price payable at Closing shall be reduced by the Allocated Value of such Environmental Defect Property.

All other remedies are hereby expressly waived by Buyer.

(c)         Termination Without Breach . In the event that this Agreement is terminated under Section  13.1 under circumstances other than those described in Section  13.3(a) or (b) , Buyer shall be entitled to receive back the entirety of the Performance Deposit, free of any claims by Seller with respect thereto.
