PURCHASE PRICE AND PAYMENT

Section 3.1 Purchase Price. The purchase price for the sale and conveyance of the Purchased Equity to Buyer is $610,000,000.00 (the “Purchase Price”), subject to adjustment in accordance with the terms of this Agreement. The “Adjusted Purchase Price” shall be the Purchase Price, less the Deposit, as:

(a) (i) decreased by the amount of cash or cash equivalents of the Company distributed from and after the Effective Time until the Closing to Seller or any of its Affiliates (other than the Acquired Companies) or (ii) increased by the amount of any cash or cash equivalents contributed to the Acquired Companies from and after the Effective Time until the Closing by Seller or any of its Affiliates (other than the Acquired Companies);

(b) (i) increased by the amount of the Effective Time Net Working Capital, if positive or (ii) decreased by the amount of the Effective Time Net Working Capital, if negative (it being understood that if the Effective Time Net Working Capital is negative, such amount shall be the absolute value thereof);

(c) increased by any amounts paid by Seller or any of its Affiliates (other than the Acquired Companies) on behalf of the Acquired Companies from and after the Effective Time and prior to Closing (other than amounts paid in connection with the dispute, cure or attempted cure of any Title Defect or a breach of any representation or warranty of Seller under this Agreement (or the dispute, cure or attempted cure of any condition or other matter that would constitute a breach of this Agreement by Seller or be subject to indemnification by Seller under this Agreement had any such condition or other matter not been cured, without regard for the Deductible) and other amounts paid in connection with this Agreement and the transactions contemplated hereby, including any Transaction Costs and any other amounts paid pursuant to Sections 8.16 and 8.22), as reflected on Schedule 3.1(c);

(d) increased or decreased by the fair market value of the Product Hedging Contracts that are not novated to the Seller as of the Closing in accordance with Section 8.17;

(e) decreased by the sum of (i) the principal amount of all Indebtedness owing by either Acquired Company to any Person (other than Seller, either Acquired Company or any of their Affiliates) as of the Effective Time and/or as of the date hereof (without duplication), (ii) all interest that has accrued as of the Effective Time and/or as of the date hereof (without duplication) on such Indebtedness and all interest that accrues from the Effective Time and/or as of the date hereof (without duplication) through the Closing Date on such Indebtedness and (iii) all prepayment penalties, premiums, fees and other similar costs and expenses due and owing in connection with the repayment of such Indebtedness;

(f) decreased by the amount of any Transaction Costs to the extent not reflected in Effective Time Net Working Capital;

(g) decreased by the amount any Casualty Losses, individually that exceed the insurance proceeds, condemnation awards and other payments arising from such Casualty Losses, except to the extent such adjustment (i) is waived by Buyer pursuant to Section 8.11 or (ii) does not exceed $100,000;

(h) decreased by any amounts paid by either Acquired Company pursuant to Section 8.22;

(i) decreased for Title Defects pursuant to Article 7;

(j) increased by $10,000,000 if the Company (i) submits a formal well completion proposal to its working interest partner in the Wang Well pursuant to the terms of the applicable Offshore Operating Agreement or (ii) actually commences an attempt to complete the Wang Well; and

(k) decreased by $30,000,000 if (i) the condition in Section 3.1(j) has not occurred and (ii) the Company, in good faith, enters into an arms-length contract with a reputable independent contractor to plug and abandon the Wang Well; provided, however, if, as of Closing, neither the condition to the Purchase Price adjustment set forth in Section 3.1(j) nor the condition set forth in Section 3.1(k) has occurred, then the Closing Payment shall be reduced by $30,000,000, and Buyer shall deposit with the Escrow Agent $40,000,000, which shall be disbursed as follows: (x) if the condition in Section 3.1(j) occurs within twelve (12) months of the Closing Date, Seller and Buyer shall jointly instruct the Escrow Agent to disburse to Seller $40,000,000, (y) if the condition in Section 3.1(k) occurs within twelve (12) months of the Closing Date, Buyer and Seller shall jointly instruct the Escrow Agent to disburse to Buyer $40,000,000, or (z) if neither the condition set forth in Section 3.1(j) nor the condition set forth in Section 3.1(k) occurs within twelve (12) months of the Closing Date, then Buyer and Seller shall jointly instruct the Escrow Agent to disburse to Seller $30,000,000 and to disburse to Buyer $10,000,000.

In calculating the Adjusted Purchase Price pursuant to this Section 3.1, no adjustment may be (1) accounted for in more than one of the paragraphs (a) through (k) above or (2) made on account of any of the actions, activities or obligations contemplated by Section 8.13. As further consideration for the sale and conveyance of the Purchased Equity, prior to the Closing, the Company shall assign to Seller the overriding royalty interests set forth on Schedule 3.1.

Section 3.2 Payment. Contemporaneous with the execution of this Agreement, Buyer has deposited an amount equal to $30,000,000.00 with the Escrow Agent to be held and disbursed by the Escrow Agent in accordance with the terms and conditions of the Escrow Agreement (the “Deposit”). At the Closing, Buyer shall wire transfer the Closing Payment in immediately available funds to the account specified in Schedule 3.2.

Section 3.3 Adjusted Purchase Price and Post-Closing Purchase Price Adjustments.

(a) Not later than five (5) Business Days prior to the Closing Date, Seller shall prepare and deliver to Buyer a settlement statement (the “Effective Time Settlement Statement”) calculating the amount equal to the Adjusted Purchase Price giving effect to Seller’s good faith estimate of the adjustments provided for in Section 3.1 (or, if then determinable, the final amounts thereof), which statement shall contain an estimated consolidated balance sheet of the Acquired Companies as of the Effective Time (without giving effect to the transactions contemplated herein), and a reasonably detailed and good faith estimate of the Effective Time Net Working Capital (the “Estimated Effective Time Net Working Capital”) (which shall be calculated in a manner consistent with the calculations set forth in Exhibit 3.3). Buyer shall have three (3) Business Days to review the Effective Time Settlement Statement, including the Estimated Effective Time Net Working Capital, from Buyer’s receipt thereof. Prior to the expiration of such three (3) Business Day review period, Buyer may submit a written report containing any changes Buyer proposes to be made to the Effective Time Settlement Statement, including to the Estimated Effective Time Net Working Capital. Seller and Buyer shall agree on a final settlement statement no later than one (1) Business Day prior to Closing; provided, however, if Seller and Buyer are unable to agree, then, subject to Section 3.3(b), Seller’s determination with respect to those items on which Seller and Buyer were unable to agree and the Parties’ determination with respect to those agreed upon items shall be used for purposes of the payment to be made at the Closing, including with respect to the calculation of the Estimated Effective Time Net Working Capital. The calculation delivered by Seller in accordance with this Section 3.3(a), as adjusted in accordance with the immediately preceding sentence, if applicable, shall constitute the dollar amount to be paid by Buyer to Seller at the Closing (together with any adjustments set forth in Sections 3.1(j), 3.1(k), 7.2(c)(ii) and 7.5, the “Closing Payment”).

(b) As soon as reasonably practicable after the Closing but not later than the ninetieth (90th) day following the Closing Date, Buyer shall prepare and deliver to Seller a draft statement (the “Post-Closing Statement”) setting forth the final calculation of the Adjusted Purchase Price taking into account any adjustments pursuant to Section 3.1 (including Title Defects, if any, finally resolved pursuant to Article 7), which statement shall contain the consolidated balance sheet of the Acquired Companies as of the Effective Time (without giving effect to the transactions contemplated hereby), and a reasonably detailed and good faith calculation of the Effective Time Net Working Capital (which shall be calculated in a manner consistent with the calculations set forth in Exhibit 3.3). As soon as reasonably practicable but not later than the thirtieth (30th) day following receipt of Buyer’s statement hereunder, Seller shall deliver to Buyer a written report (an “Adjustment Notice”) containing any changes (other than with respect to Title Defects that are to be resolved pursuant to Article 7) Seller proposes to be made in such statement, including to the Effective Time Net Working Capital. Seller shall be deemed to have accepted and agreed to all items in the Post-Closing Statement, including Buyer’s calculation of the Effective Time Net Working Capital, other than such matters that are proposed to be changed in the Adjustment Notice and other than Title Defects that have not been finally resolved pursuant to Article 7 (it being understood that if Seller does not deliver an Adjustment Notice within such thirty (30) day period, then Seller shall be deemed to have accepted and agreed to all items in the Post-Closing Statement). The Parties shall undertake to agree on the final Adjusted Purchase Price, subject to further adjustment pursuant to Sections 3.1(j), 3.1(k), 7.2(c)(ii) and 7.5, no later than ten (10) Business Days after delivery of the Adjustment Notice. If the final Adjusted Purchase Price is:

(i) mutually agreed upon in writing by Seller and Buyer during such ten (10) Business Day period or if Seller does not deliver an Adjustment Notice within the thirty (30) day period, the final Adjusted Purchase Price, subject to further adjustment pursuant to Sections 3.1(j), 3.1(k), 7.2(c)(ii) and 7.5, shall be conclusive and binding on the Parties; or

(ii) not mutually agreed upon by Seller and Buyer during such ten (10) Business Day period, then Pannell, Kerr, ▇▇▇▇▇▇ ▇▇ (the “Accountant”) shall resolve any disagreements (other than with respect to Title Defects). Should Pannell, Kerr, ▇▇▇▇▇▇ ▇▇ fail or refuse to agree to serve as Accountant within ten (10) days after written request from any Party to serve and the Parties fail to agree in writing on a replacement Accountant within five (5) days after the end of that ten (10) day period, or should no replacement Accountant agree to serve within fifteen (15) days after the original written request pursuant to this sentence, the Accountant shall be appointed by the Houston, Texas office of the American Arbitration Association. In connection with the engagement of the Accountant, each of Seller and Buyer shall execute such engagement, indemnity and other agreements as the Accountant shall require as a condition to such engagement. The Accountant shall determine as promptly as practicable, but in any event within thirty (30) days after the selection of the Accountant, based solely on written submissions provided by Buyer and Seller to the Accountant (and without independent investigation on the part of the Accountant) within ten (10) days following the Accountant’s selection, whether and to what extent (if any) Buyer’s Post-Closing Statement, including the Effective Time Net Working Capital, requires adjustment. In resolving any disputed item, the Accountant shall act as an expert and not an arbitrator and shall resolve only the items set forth in the Adjustment Notice that are still in dispute and may not assign a value to any item greater than the highest value for such item claimed by either Party or less than the lowest value for such item claimed by either Party. The fees and expenses of the Accountant shall be paid by the Parties in inverse proportion to the relative success of their claims. The determination of the Accountant shall be final, conclusive and binding on Buyer and Seller. The date on which the final Adjusted Purchase Price is finally determined in accordance with this Section 3.3(b) is referred to as the “Determination Date.”

(c) Any difference in the Closing Payment and the final Adjusted Purchase Price shall be paid by the owing Party to the owed Party within five (5) Business Days of the Determination Date. Any post-Closing payment pursuant to this Section 3.3 shall bear interest from the Closing Date to the date of payment at the Agreed Rate.

(d) Seller shall reasonably assist Buyer in preparation of the Post-Closing Statement of the Adjusted Purchase Price under Section 3.3(b), including the Effective Time Working Capital, by furnishing invoices and receipts in Seller’s possession, reasonable access to personnel and such other assistance as may be reasonably requested by Buyer to facilitate such process post-Closing.

(e) All payments made or to be made under this Agreement to Seller (other than the Deposit and any other amounts held by the Escrow Agent, which shall be released pursuant to the Escrow Agreement) shall be made by electronic transfer of immediately available funds to

Seller to the account set forth in Schedule 3.2, or to such other bank and account as may be specified by Seller in writing to Buyer. All payments made or to be made hereunder to Buyer (other than the Deposit and any other amounts held by the Escrow Agent, which shall be released pursuant to the Escrow Agreement) shall be by electronic transfer or immediately available funds to the account set forth in Schedule 3.3(e) or to such other bank and account as may be specified by Buyer in writing to Seller.

(f) Notwithstanding anything to the contrary, the calculation of Effective Time Net Working Capital and Estimated Effective Time Net Working Capital shall not include as Current Assets any accounts receivable that are not probable to lead to the receipt of cash by an Acquired Company, which, for the avoidance of doubt shall include, but not be limited to, any amounts owed to the Acquired Companies by Implicit Oil & Gas, L.P. as Joint Interest ▇▇▇▇▇▇▇▇ with respect to WC ▇▇▇, ▇▇ ▇▇▇, ▇▇ ▇▇▇ & ▇▇▇, ▇▇ ▇▇▇▇, MP 233 or ST 145, provided that in the event the Acquired Companies collect any such amounts that have been excluded from the calculation of Effective Time Net Working Capital prior to the first anniversary of the Closing Date, such amounts shall be paid to Seller within five (5) Business Days of receipt thereof by the Acquired Companies pursuant to the provisions of Section 3.3(e). In addition, the one-time payment referenced in Item 2 of Schedule 8.1(e)(iii) shall not be included as a Current Liability in the calculation of Effective Time Net Working Capital or Estimated Effective Time Net Working Capital.

(ii) Buyer has delivered to Seller correct and complete copies of:

(1) executed commitment letters dated as of the date hereof (including all exhibits, schedules and annexes thereto, collectively, the “Equity Funding Letters”) from the parties set forth therein (collectively, the “Equity Providers”) pursuant to which the Equity Providers have committed, subject to the terms and conditions therein, to invest the amounts set forth therein (the “Equity Financing”); and

(2) an executed commitment letter dated as of the date hereof, as the same may be amended or replaced pursuant to Section 8.28(a) and including any executed commitment letter (or similar agreement) for Alternate Financing, in each case, pursuant to Section 8.28(c), including all exhibits, schedules and annexes thereto (the “Debt Commitment Letter” and, together with the Equity Funding Letters, the “Financing Letters”) from the financial institutions identified therein (including any Affiliates thereof, the “Debt Providers”) pursuant to which, and subject to the terms and conditions therein, the Debt Providers have committed to provide or cause to be provided the debt financing in the amounts set forth therein (the “Debt Financing,” and together with the Equity Financing, the “Financing”).

Buyer or an Affiliate of Buyer has fully paid or has caused to be fully paid any and all commitment fees or other fees in connection with the Financing Letters that are payable on or prior to the date hereof.

Assuming the accuracy of the representations and warranties set forth in Sections 4.1 and 4.2 and the performance by Seller of the covenants contained in Section 8.28 of this Agreement, as of the date of this Agreement, no event has occurred that, with or without notice, lapse of time or both, would or would reasonably be expected to constitute a default or breach on the part of Buyer or, to the Knowledge of Buyer, any other parties thereto, under the Financing Letters. As of the date of this Agreement, Buyer is not aware of any fact, occurrence or condition that makes any of the assumptions or statements set forth in the Financing Letters inaccurate in any material respect or that would cause any of the commitments provided in the Financing Letters to be terminated or ineffective or, assuming satisfaction of the closing condition set forth in Section 9.2(a), any reason to believe that any of the conditions precedent set forth therein will not be met.

(i) No Distribution. Buyer is an experienced and knowledgeable investor in the oil and gas business, Buyer is able to bear the economic risks of its acquisition and ownership of the Purchased Equity and ownership of the Assets, and Buyer is capable of evaluating (and has evaluated) the merits and risks of the Purchased Equity and Assets and Buyer’s acquisition and ownership thereof. Prior to entering into this Agreement, Buyer was advised by its counsel and such other persons it has deemed appropriate concerning this Agreement and has relied solely on an independent investigation and evaluation of, and appraisal and judgment with respect to, the geologic and geophysical characteristics of the Subject Interests and the estimated reserves recoverable therefrom. Buyer has sufficient knowledge and experience in financial and business matters so as to be able to evaluate the merits and risk of an investment in the Purchased Equity and is able financially to bear the risks thereof, and understands that the Purchased Equity will,

upon purchase, be characterized as “restricted securities” under state and federal securities Laws and that under such Laws and applicable regulations the Purchased Equity may be resold without registration under such Laws only in certain limited circumstances. Buyer is an “accredited investor,” as such term is defined in Regulation D of the Securities Act of 1933, as amended, and will acquire the Purchased Equity for its own account and not with a view to a sale or distribution thereof in violation of the Securities Act of 1933, as amended, and the rules and regulations thereunder, any applicable state blue sky laws or any other applicable securities laws.

(j) Bankruptcy. There are no bankruptcy, reorganization or arrangement proceedings pending against, being contemplated by, or to the Knowledge of Buyer, threatened against Buyer or any Affiliate of Buyer.

(k) BOEM Approval. To the Knowledge of Buyer, there is no fact or condition with respect to Buyer that may cause BOEM to withhold its unconditional approval to the transactions contemplated herein to the extent BOEM approval is required by Law.

(a) permit Buyer and its Representatives to have reasonable access, at reasonable times in the Acquired Companies’ and Seller’s offices, and in a manner so as not to interfere unduly with the business operations of the Acquired Companies or Seller, to the Acquired Companies’ books and records, including organizational documents, minute books, corporate, tax, legal, financial and other books and records of either Acquired Company, all documents pertaining to compliance of the Acquired Companies and Assets with Environmental Laws and Environmental Permits and with respect to any Environmental Condition or Environmental Liabilities, and all contracts, abstracts of title, title opinions, title files, ownership maps, lease files, assignments, division orders, and documents insofar as the same are in either Acquired Company’s or Seller’s possession and insofar as either Acquired Company or Seller may do so without, in its good faith opinion, breaching or risking a breach of agreements with other Persons or waiving or risking waiving legal privilege of either Acquired Company or Seller (other than any legal privilege with respect to any title opinions or similar title files or environmental files of either Acquired Company); provided, however, that Seller shall, and shall cause the Company to, at Buyer’s request and at no cost or expense to the Company or Seller, request waivers of such confidentiality restrictions; and

(b) subject to any required consent of any third Person, permit Buyer and its Representatives at reasonable times and at Buyer’s sole risk, cost and expense, to conduct, in the presence of the Company’s or Seller’s Representatives, reasonable inspections of the Assets; provided that, Buyer shall provide forty-eight (48) hours’ notice in accordance with Section 15.5 prior to accessing the Assets and shall have no right to drill any ▇▇▇▇▇, take any samples, make any borings or conduct any other invasive testing in connection with Buyer’s inspection absent express written authorization from Seller, to be provided or withheld in Seller’s sole and absolute discretion;

provided, however, Buyer shall comply with all applicable policies, rules and regulations of the Company, including but not limited to safety policies, with respect to such access (including without limitation executing a boarding agreement, substantially in the form of Exhibit 5.1(b), prior to boarding any of the Company’s offshore platforms) and repair any damage resulting from such inspections, and Buyer does hereby indemnify and hold harmless, release and agree to defend Seller Indemnified Persons from and against any and all Covered Liabilities arising, in whole or in part, from Buyer’s inspections, regardless of any concurrent negligence or strict liability on the part of Seller Indemnified Persons and regardless of the form of claim whether at common law, strict liability, negligence or under any statute or regulation (but expressly excluding gross negligence or willful misconduct). Nothing in this Agreement shall be construed to permit Buyer or its Representatives to have access to any files, records, contracts or documents of either Acquired Company or Seller relating to negotiating the sale of the Purchased Equity or the Assets, including any bids or offers received by Seller or the Company for the sale of the Purchased Equity or the Assets in competition with Buyer’s bid or offer, it being agreed that all such competing bids or offers shall be the sole property of Seller.

Section 5.2 Confidential Information. Buyer agrees to maintain all information made available to it pursuant to this Agreement confidential and to cause its Affiliates and Representatives to maintain all information made available to them pursuant to this Agreement confidential, all as provided in that certain confidentiality agreement dated March 27, 2012, as may be amended from time to time (the “Confidentiality Agreement”), by and between Seller and Buyer, which shall continue in full force and effect and the terms of which are incorporated herein by reference and made a part of this Agreement. Notwithstanding anything herein or in the Confidentiality Agreement to the contrary, on the Closing Date the Confidentiality Agreement shall be terminated and of no further force or effect and Buyer shall have no further obligation with respect to confidentiality pursuant to this Section 5.2. From and after the Closing for a period of three (3) years, Seller shall, and shall cause its Affiliates and Representatives to, hold in confidence any and all information, whether written or oral, concerning either Acquired Company prior to the Closing Date or the terms of this Agreement, except to the extent that such information (a) is generally available to and known by the public through no fault of Seller or any of its Affiliates or Representatives; or (b) is lawfully acquired by Seller or any of its Affiliates or Representatives from and after the Closing from sources that are not prohibited from disclosing such information by a legal, contractual or fiduciary obligation. If Seller or any of its Affiliates or Representatives are compelled to disclose any information by judicial or administrative process or by other requirements of Law, Seller shall, if legally permitted, promptly notify Buyer in writing and shall disclose only that portion of such information that Seller, its Affiliate or Representative is advised by its counsel that it is legally required to disclose, provided that, upon Buyer’s written request and at Buyer’s sole cost and expense, Seller shall use commercially reasonable efforts to obtain an appropriate protective order or other reasonable assurance that confidential treatment will be accorded such information.

ARTICLE 7

TITLE ADJUSTMENTS

Section 7.1 General Disclaimer of Warranties and Representations. Without limiting Buyer’s right to adjust the Purchase Price by operation of Section 7.2, neither Seller nor the Company makes any warranty or representation, express, implied, statutory or otherwise, with respect to either Acquired Company’s title to any of the Subject Interests, and Buyer hereby acknowledges and agrees that, absent fraud by Seller or either of the Acquired Companies, Buyer’s sole remedy for any defect of title, including any Title Defect with respect to any of the Subject Interests shall be pursuant to the procedures set forth in this Article 7, which remedies shall cease, and be deemed to be finally and conclusively satisfied, in all respects, upon the Closing, except to the extent set forth in this Article 7.

Section 7.2 Buyer’s Title Review.

(a) Buyer’s Assertion of Title Defects. Prior to the expiration of the thirty (30) day period commencing on the execution of this Agreement (the “Title Examination Period”), Buyer may furnish Seller written notice meeting the requirements of this Section 7.2(a) (the “Title Defect Notice”) setting forth any matters that, in Buyer’s reasonable opinion, constitute Title Defects and that Buyer is asserting as a Title Defect with respect to all or any portion of a Property Subdivision pursuant to this Article 7. For all purposes of this Agreement, absent fraud by Seller or either of the Acquired Companies, Buyer shall be deemed to have waived all defects in title to the Assets, including without limitation, any Title Defects that Buyer fails to assert as a Title Defect by a Title Defect Notice given to Seller on or before the expiration of the Title Examination Period. To be effective, Buyer’s Title Defect Notice must include (i) a brief description of the matter constituting the asserted Title Defect, (ii) the claimed Title Defect Amount attributable thereto, and (iii) supporting documents reasonably necessary (and available to Buyer) for Seller (as well as any title attorney or examiner hired by Seller) to verify the existence of such asserted Title Defect. Seller shall respond promptly in writing to each Title Defect Notice and negotiate with Buyer in an effort to come to agreement with Buyer with respect to a resolution with respect to each Title Defect asserted in such Title Defect Notice. To give Seller an opportunity to commence reviewing and curing Title Defects, Buyer agrees to use its commercially reasonable efforts to give Seller, on or before the end of each calendar week during the Title Examination Period, written notice of all Title Defects discovered by Buyer during the calendar week preceding the calendar week then ending, which may be preliminary in nature and supplemented prior to the end of the Title Examination Period; provided that the failure of Buyer to provide Seller with such weekly written notice of any Title Defect shall not in any way prevent Buyer from notifying Seller of a Title Defect prior to the expiration of the Title Examination Period. Buyer shall also promptly furnish Seller with written notice of any Title Credit that is discovered by any of Buyer’s Representatives while conducting Buyer’s title review, due diligence or investigation with respect to the Subject Interests and Property Subdivisions.

(b) Purchase Price Allocations. A portion of the Purchase Price has been allocated to the various Subject Interests in Property Subdivisions in the manner and in accordance with the respective values set forth in the Property Schedule (the portion of the Purchase Price allocated to each Property Subdivision, as such allocation may be adjusted pursuant to the immediately succeeding sentence, shall be referred to in this Agreement, as such Property Subdivision’s “Allocated Value”). If any adjustment is made to the Purchase Price pursuant to this Section 7.2, a corresponding adjustment shall be made to the portion of the Purchase Price allocated to the affected Subject Interests in Property Subdivisions set forth in the Property Schedule.

(i) Seller shall have until two (2) days prior to the Closing Date, at its cost and expense, if it so elects but without obligation, to cure all or a portion of such asserted Title Defects. Subject to Section 7.2(c)(ii) and Seller’s continuing right to dispute the existence of a Title Defect and/or the Title Defect Amount asserted with respect thereto, if Seller within such time fails to cure any Title Defect of which Buyer has given a timely Title Defect Notice and Buyer has not and does not waive (in writing) the same on or before the day immediately preceding the Closing Date, then the Subject Interest in the Property Subdivision affected by such uncured and unwaived Title Defect shall be a “Title Defect Property.”

(ii) If Buyer furnishes to Seller timely Title Defect Notice(s) of one or more Title Defects and the same are not waived or cured as provided in Section 7.2(c)(i), Seller may elect to close the transactions contemplated hereby and retain the right to cure any of such Title Defects after Closing. In such event, but subject to Seller’s continuing right to dispute the existence of a Title Defect and/or the Title Defect Amount asserted with respect thereto pursuant to the provisions of this Article 7, (A) the Purchase Price shall be subject to reduction pursuant to Section 7.2(d) taking into account all Title Defect Amounts attributable to the Title Defect Properties affected by the Title Defects that Seller may elect to cure after Closing, provided that any portion of any agreed upon Title Defect Amounts for Title Defects that Seller has elected to cure after Closing that would have resulted in a reduction in the Purchase Price pursuant to Section 7.2(d) shall instead be deposited with the Escrow Agent and disbursed pursuant to the terms and provisions of the Escrow Agreement or other mutually agreeable escrow agreement entered into by the Parties pending such cure. Seller shall have one hundred eighty (180) days (to Buyer’s reasonable satisfaction) after the Closing Date in which to attempt to cure any such Title Defects. If Seller cures any such Title Defect, Buyer and Seller shall jointly instruct the Escrow Agent to disburse to Seller an amount equal to the Title Defect Amount with respect to the Title Defect that is so cured, provided that the aggregate amount of all payments to Seller pursuant to this Section 7.2(c) with respect to cured Title Defects shall not exceed the amount deposited with the Escrow Agent as a result of such Title Defects. If Seller does not cure (to Buyer’s reasonable satisfaction) all such Title Defects by the end of such one hundred eighty (180) day period, then Buyer and Seller shall jointly instruct the Escrow Agent to disburse to Buyer all amounts that remain deposited with the Escrow Agent as a result of such uncured Title Defects; provided, however, that in no event shall Buyer and Seller instruct the Escrow Agent to disburse to Buyer any amounts held by the Escrow Agent with respect to any Deferred Adjustment

Claims if, at the end of such one hundred eighty (180) day period, such Deferred Adjustment Claims have not then been resolved. The Purchase Price shall be deemed reduced by any such disbursement to Buyer. For the avoidance of doubt, to the extent that the Title Defect Amount with respect to a Title Defect is reduced or eliminated entirely as a result of Seller curing such Title Defect, the amount of such reduction in the Title Defect Amount shall no longer be included for purposes of determining whether the Available Deductible Amount has been exceeded.

(d) Buyer’s Title Adjustments. As Buyer’s sole and exclusive remedy with respect to Title Defects, Buyer shall be entitled to reduce the Purchase Price by the amount, if any, by which the aggregate amount of all Title Defect Amounts with respect to all Title Defect Properties exceeds the sum (the “Available Deductible Amount”) of $10,000,000 plus the aggregate amount of all Title Credits. “Title Defect Amount” shall mean, with respect to a Title Defect Property, the amount by which the value of such Title Defect Property is impaired as a result of the existence of one or more uncured and unwaived Title Defects, which amount shall be determined as follows and subject to the following conditions:

(i) If the Title Defect results from the Acquired Companies combined having a lesser Net Revenue Interest in such Title Defect Property than the Net Revenue Interest specified therefor in the Property Schedule, the Title Defect Amount shall be equal to the product obtained by multiplying the Allocated Value of such Title Defect Property in the Property Schedule by a fraction, the numerator of which is the reduction in the Net Revenue Interest and the denominator of which is the Net Revenue Interest specified for such Title Defect Property in the Property Schedule.

(ii) If the Title Defect results from the existence of a Lien that secured Indebtedness, the Title Defect Amount shall be an amount sufficient to discharge and release such Lien.

(iii) If the Title Defect results from any matter not described in clauses (i) or (ii) above, including the Acquired Companies combined having a greater Working Interest in a Title Defect Property than the Working Interest specified therefor in the Property Schedule, the Title Defect Amount shall take into account the Allocated Value of such Title Defect Property, the portion of the Title Defect Property affected by the Title Defect, the legal effect of the Title Defect, the potential discounted economic effect of the Title Defect over the life of the Title Defect Property, the values placed upon the Title Defect by Buyer and Seller and such other factors as are reasonably necessary to make a proper evaluation and determination of such adjustment.

(iv) If a Title Defect is not effective or does not affect a Title Defect Property throughout the entire remaining productive life of such Title Defect Property, such fact shall be taken into account in determining the Title Defect Amount.

(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. For example, but without limitation, if a Lien affects more than one Title Defect Property, the amount necessary to discharge such Lien shall be allocated

among the Title Defect Properties so affected (in the ratios of the Allocated Values of such Title Defect Properties) and the amount so allocated to a Title Defect Property shall be included only once in the Title Defect Amount therefor, but such Title Defect Amount shall not be deemed allocated proportionately with respect to determining whether such Title Defect Amount exceeds the de minimis amount set forth in Section 7.2(d)(ix).

(vi) The Title Defect Amount attributable to a Title Defect Property or any portion thereof shall not exceed such Title Defect Property’s Allocated Value.

(vii) No Title Defect Amount shall be allowed on account of and to the extent that an increase in the Acquired Companies’ Working Interest in a Property Subdivision has the effect of proportionately increasing the Acquired Companies’ Net Revenue Interest in such Property Subdivision.

(viii) Notwithstanding the foregoing, if the Title Defect Amount determined pursuant to the foregoing with respect to a Title Defect Property is $200,000 or less, then the Title Defect Amount with respect to such Title Defect Property shall be deemed zero; provided, however, that, in determining whether the foregoing de minimis amount has been exceeded, all Title Defect Amounts with respect to each Property Subdivision shall be aggregated.

(ix) If the Parties agree as to the Title Defect Amount, the Title Defect Amount shall be the agreed upon amount.

Section 7.3 Determination of Title Defects. The Subject Interest in a portion of a Property Subdivision shall be deemed to have a “Title Defect” if the Acquired Companies do not have Defensible Title thereto as of the date hereof and as of the Closing Date. Notwithstanding any other provision in this Agreement to the contrary, the following matters shall be deemed to be Permitted Encumbrances and shall not be asserted as, and shall not constitute, Title Defects: (a) defects arising out of lack of survey, unless a survey is required by Law, (b) defects arising out of lack of corporate authorization, unless Buyer provides affirmative evidence that such corporate action was not authorized and results in another Person’s superior claim of title to the relevant Subject Interest or portion thereof, (c) defects that have been cured by applicable statutes of limitations or statutes for prescription and (d) any encumbrance, loss of title or defect resulting from Seller’s or the Acquired Companies’ election not to participate in an operation or maintain an Asset for which Buyer has given its prior written consent not to participate or maintain.

Section 7.4 Title Credit. A “Title Credit” shall mean, with respect to the Subject Interest in a Property Subdivision, the amount by which the Allocated Value of the Subject Interest in such Property Subdivision is enhanced by virtue of (a) the Acquired Companies combined having a greater Net Revenue Interest in such Property Subdivision than the Net Revenue Interest specified therefor in the Property Schedule without causing a greater than proportionate increase in the Acquired Company’s Working Interest in such Property Subdivision or (b) the Acquired Companies combined having a lesser Working Interest in such Property Subdivision than the Working Interest specified therefor in the Property Schedule that

does not proportionately decrease (of equal or greater amount) the Acquired Company’s Net Revenue Interest in such Property Subdivision, which amount shall be determined as follows:

(i) If the Title Credit results from the Acquired Companies having a greater Net Revenue Interest in such Property Subdivision than the Net Revenue Interest specified therefor in the Property Schedule, the Title Credit shall be equal to the product obtained by multiplying the Allocated Value of such Property Subdivision in the Property Schedule by a fraction, the numerator of which is the increase in the Net Revenue Interest and the denominator of which is the Net Revenue Interest specified for such Property Subdivision in the Property Schedule.

(ii) If the Title Credit results from the Acquired Companies having a lesser Working Interest in a Property Subdivision than the Working Interest specified therefor in the Property Schedule, the Title Credit shall take into account the Allocated Value of such Property Subdivision, the portion of the Property Subdivision affected by the Title Credit, the legal effect of the Title Credit, the potential increased economic effect of the Title Credit over the life of the Property Subdivision, the values placed upon the Title Credit by Buyer and Seller and such other factors as are reasonably necessary to make a proper evaluation and determination of such adjustment.

(iii) In determining the amount of Title Credits, the principles and methodology set forth in clauses (iv), (v) and (vi) of Section 7.2(d) shall be applied, mutatis mutandis.

(iv) No Title Credit shall be allowed on account of and to the extent that a decrease in the Acquired Companies’ Working Interest in a Property Subdivision has the effect of proportionately decreasing the Acquired Companies’ Net Revenue Interest in such Property Subdivision or disproportionately decreasing the Acquired Companies’ Net Revenue Interest in such Property Subdivision greater than the decrease in the corresponding Working Interest.

(v) Notwithstanding the foregoing, if the aggregate amount of Title Credits determined pursuant to the foregoing with respect to a Property Subdivision is $200,000 or less, then the Title Credits with respect to such Property Subdivision shall be deemed zero; provided, however, that, in determining whether the foregoing de minimis amount has been exceeded, all Title Benefit Amounts with respect to each Property Subdivision shall be aggregated.

Section 7.5 Deferred Claims and Disputes. In the event that Buyer and Seller have not agreed upon the existence of one or more Title Defects, the cure thereof, or one or more adjustments, credits or offsets claimed by Buyer or Seller pursuant to and in accordance with the requirements of this Article 7, any such dispute or claim (a “Deferred Adjustment Claim”) shall be settled pursuant to this Section 7.5 and, except as provided in Sections 9.1(f)(i) and 9.2(f)(i), shall not prevent or delay Closing. In no event shall any Title Defect Amount asserted by Buyer as a Deferred Adjustment Claim exceed the amount asserted by Buyer therefor prior to the end of the Title Examination Period in the Title Defect Notice applicable thereto and delivered in accordance with Section 7.2, and in no event shall any Title Defect Amount asserted by Seller as

a Deferred Adjustment Claim be less than the amount asserted by Seller in response to Buyer’s notices. With respect to each potential Deferred Adjustment Claim, Buyer and Seller shall deliver to the other a written notice describing each such potential Deferred Adjustment Claim, the amount in dispute and a statement setting forth the facts and circumstances that support such Party’s position with respect to such Deferred Adjustment Claim. In such event, but subject to Seller’s continuing right to cure a Title Defect pursuant to the provisions of this Article 7, the Purchase Price shall be subject to reduction pursuant to Section 7.2(d) taking into account all Title Defect Amounts attributable to the Title Defect Properties affected by the Title Defects that are the subject of Deferred Adjustment Claims, provided that any portion of the aggregate amount of all Title Defect Amounts asserted by Buyer as Deferred Adjustment Claims that would have resulted in a reduction in the Purchase Price pursuant to Section 7.2(d) shall instead be deposited with the Escrow Agent and disbursed pursuant to the terms and provisions of the Escrow Agreement or other mutually agreeable escrow agreement entered into by the Parties pending resolution. On or prior to the thirtieth (30th) consecutive calendar day following the Closing Date (the “Deferred Matters Date”), Seller and Buyer shall attempt in good faith to reach agreement on the Deferred Adjustment Claims and, ultimately, to resolve by written agreement all disputes regarding the Deferred Adjustment Claims. Upon any resolution, Buyer and Seller shall jointly instruct the Escrow Agent to disburse an amount equal to the resolved amount to the Party so determined by the Parties. If such resolved amount is disbursed to Buyer, then the Purchase Price shall be deemed to be reduced by the amount so disbursed. Any Deferred Adjustment Claims that are not so resolved on or before the Deferred Matters Date may be submitted by either Party to final and binding arbitration in accordance with the Arbitration Procedures. Notwithstanding anything herein provided to the contrary, including Section 7.2(c), but without limiting Seller’s rights under Section 7.2(c)(ii), Seller shall be entitled to cure any Title Defect that gives rise to a Deferred Adjustment Claim at any time prior to the point in time when a final and binding written decision of the Sole Arbitrator (as defined in the Arbitration Procedures) is made with respect thereto in accordance with the Arbitration Procedures. Upon the final and binding written decision of the Sole Arbitrator, Buyer and Seller shall jointly instruct the Escrow Agent to disburse the amount in escrow in accordance with the decision of the Sole Arbitrator; provided, however, that in no event shall Buyer and Seller instruct the Escrow Agent to disburse to Buyer any amounts held by the Escrow Agent with respect to the Title Defect Properties affected by the Title Defects that Seller elected to cure after Closing if, at the time of the Sole Arbitrator’s decision, Title Defects that Seller elected to cure remain subject to cure pursuant to Section 7.2(c)(ii). In the event a dispute regarding the cure of a Title Defect is submitted to the Sole Arbitrator for resolution, the standard for determining whether a Title Defect has been cured shall be determined in the Sole Arbitrator’s discretion and not that the cure is reasonably satisfactory to Buyer. The Purchase Price shall be deemed to be reduced by the amount so disbursed to Buyer.

Section 7.6 No Duplication. Notwithstanding anything herein provided to the contrary, if a Title Defect results from any matter that could also result in the breach of any representation or warranty of Seller set forth in Article 4, then Buyer shall be entitled to assert such matter only as a Title Defect pursuant to this Article 7 and shall be precluded from also asserting such matter as the basis of the breach of any such representation or warranty.

(iii) maintain and keep the Assets in full force and effect, except where such failure is due to (A) the failure to pay a delay rental, royalty, shut in royalty or other payment by mistake or oversight (including either Acquired Company’s negligence) unless caused by either Acquired Company’s gross negligence or willful misconduct, or (B) the failure to participate in an operation that Buyer does not timely approve; and

(iv) use commercially reasonable efforts to maintain each Acquired Company’s relationships with suppliers, customers and others having material business relations with either Acquired Company so that they will be preserved for Buyer on and after the Closing Date.

(e) Contracts and Agreements. Seller shall cause the Acquired Companies to not:

(i) grant or create any Preference Right or Transfer Requirement with respect to the Assets except (A) in connection with the performance by either Acquired Company

of an obligation under a Material Contract existing on the date hereof or (B) in connection with the renewal or extension of Assets after the date hereof if granting or creating such Preference Right or Transfer Requirement is a condition of such renewal or extension, but, in each of the cases of clauses (A) and (B), only if such Preference Right or Transfer Requirement is set forth on Schedule 4.2(p);

(iv) amend, modify or terminate the non-compete agreement entered into by and between the Company and ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ dated as of the date hereof;

(v) voluntarily relinquish either Acquired Company’s position as operator with respect to any of the Assets; or

(vi) agree to do any of the items enumerated in this Section 8.1.

Notwithstanding the foregoing provisions of this Section 8.1, Seller and the Acquired Companies shall have the right to novate, close-out, terminate, or otherwise settle any outstanding Product Hedging Contracts prior to Closing in accordance with Section 8.17 without obtaining Buyer’s consent or approval. Buyer’s approval of any action: (i) set forth in Sections 8.1(a), 8.1(b)(ii), 8.1(c), 8.1(e)(i), 8.1(e)(iii) and 8.1(e)(iv) may be granted or withheld in its sole discretion; and (ii) set forth in Sections 8.1(b)(i), 8.1(b)(iii), 8.1(d), or 8.1(e)(ii) above shall not be unreasonably withheld, conditioned or delayed.

Section 8.2 Qualifications on Conduct; Operations After Closing.

(a) Emergencies; Legal Requirements. The Company and/or Seller may take (or not take, as the case may be) any of the actions mentioned in Section 8.1 if reasonably necessary to avert or reduce imminent danger to the life or health of any Person or Persons, to prevent or mitigate any imminent material violation of Laws or to prevent or mitigate any imminent loss of or damage to any material Asset or other property of either Acquired Company and for which

action or actions, time is of the essence. Seller shall notify Buyer promptly after taking any such action.

(b) Non Operated Properties. If either Acquired Company is not the operator of a particular portion of the Assets, the obligations of Seller in Section 8.1 with respect to such portion of the Assets, which have reference to operations or activities that pursuant to existing contracts are carried out or performed by the operator, shall be construed to require only that the Acquired Companies exercise their contractual rights in accordance with the foregoing and that Seller use its commercially reasonable efforts (without being obligated to incur any expense or institute any cause of action) to cause either Acquired Company to cause the operator of such portion of the Assets to take or not take such actions or render such performance or not render such performance as required by Section 8.1 within the constraints of the applicable operating agreements and other applicable agreements. Seller shall notify Buyer promptly if the operator of such portion of the Assets fails to take action or takes action prescribed in Section 8.1 promptly after the taking of any such action or the failure to take any such action.

Section 8.3 Non-Competition; Non-Solicitation.

(a) For a period of twelve (12) months commencing on the Closing Date (the “Restricted Period”), Seller shall not, and shall not permit any of its subsidiaries to, directly or indirectly, (i) engage in the Restricted Business in the Territory; (ii) have an equity interest in any Person that engages directly or indirectly in the Restricted Business in the Territory; or (iii) intentionally interfere in any material respect with the business relationships (whether formed prior to or after the date of this Agreement) between either Acquired Company, on the one hand, and customers or suppliers of either Acquired Company, on the other hand. Notwithstanding the foregoing, Seller and its subsidiaries may (i) own, directly or indirectly, solely as an investment, securities of any Person traded on any national securities exchange if Seller or its subsidiary, as applicable, is not a controlling Person of, or a member of a group that controls, such Person and does not, directly or indirectly, own five (5%) or more of any class of securities of such Person, and (ii) continue to perform their businesses in substantially the same manner in which Seller and its subsidiaries (other than the Acquired Companies) performed their businesses immediately prior to Closing (including the operation of the Helix Producer I, maintaining the overriding royalty interests in effect as of the Closing Date (other than those owned by the Acquired Companies), and the use of the Excluded Assets).

(b) During the Restricted Period, Seller shall not, and shall not permit any of its subsidiaries to, directly or indirectly, hire or solicit any employee of either Acquired Company or encourage any such employee to leave such employment or hire any such employee who has left such employment; provided, that nothing in this Section 8.3(b) shall prevent Seller or any of its subsidiaries from hiring (i) any employee whose employment has been terminated by either Acquired Company; (ii) after 180 days from the date of termination of employment, any employee whose employment has, to the Knowledge of Seller, been terminated by the employee; or (iii) any employee who responds to a general solicitation for employment by Seller or any of its subsidiaries.

(c) During the Restricted Period, Seller shall not, and shall not permit any of its subsidiaries to, directly or indirectly, solicit or entice, or attempt to solicit or entice, any clients

or customers of either Acquired Company or potential clients or customers of either Acquired Company for purposes of diverting their business or services from either Acquired Company.

(d) Seller acknowledges that a breach or threatened breach of this Section 8.3 would give rise to irreparable harm to Buyer, for which monetary damages would not be an adequate remedy and hereby agrees that in the event of a breach or a threatened breach by Seller of any such obligations, Buyer shall, in addition to any and all other rights and remedies that may be available to it in respect of such breach, be entitled to equitable relief, including a temporary restraining order, an injunction, specific performance and any other relief that may be available from a court of competent jurisdiction (without any requirement to post bond).

(e) Seller explicitly represents and warrants to Buyer that Seller is incurring the obligations of the covenants in this Section 8.3 as an inducement to Buyer to enter into this Agreement and as an essential element of Buyer’s agreement to acquire the Purchased Equity and pay the purchase price for the Purchased Equity, and Buyer would not have done so but for the agreement by Seller to comply with the terms and provisions hereof.

(f) Seller understands and acknowledges that Buyer has made substantial investments to acquire the Purchased Equity, including its business interests, goodwill and confidential information of the Acquired Companies. Seller agrees that such investments are worthy of protection and that Buyer’s need for the protection afforded by this Section 8.3 is greater than any hardship Seller might experience by complying with its terms. Seller agrees that the limitations as to time, geographic area and scope of activity to be restrained contained in this Agreement are fair and reasonable and are not greater than necessary to protect the legitimate interests of Buyer. In the event that any covenant contained in this Section 8.3 should ever be adjudicated to exceed the time, geographic, product or service, or other limitations permitted by applicable Law in any jurisdiction, then any court is expressly empowered to reform such covenant to the maximum time, geographic, product or service, or other limitations permitted by applicable Law in such jurisdiction. The covenants contained in this Section 8.3 and each provision hereof are severable and distinct covenants and provisions. The invalidity or unenforceability of any such covenant or provision as written shall not invalidate or render unenforceable the remaining covenants or provisions hereof, and any such invalidity or unenforceability in any jurisdiction shall not invalidate or render unenforceable such covenant or provision in any other jurisdiction.

Section 8.4 Employee Matters.

(a) The Acquired Companies shall continue to employ all of the Continuing Employees after the Closing Date. Prior to the Closing Date, Buyer or one of its Affiliates (including the Acquired Companies) shall notify, in writing, individuals who are employed by an Acquired Company immediately prior to the Closing Date whether such individuals will continue in employment with the Buyer or one of its Affiliates (including the Acquired Companies) after the Closing Date either (i) as a “Retained Employee” or (ii) for a limited time period as a “Transition Employee.” Any Continuing Employee that is, for whatever reason, not designated by Buyer or one of its Affiliates (including the Acquired Companies) as a “Retained Employee” or a “Transition Employee” shall be considered for purposes of this Agreement a “Retained Employee”. For a period of at least twelve (12) months after the Closing Date, Buyer

shall, or shall cause one of its Affiliates (including the Acquired Companies) to, provide the Continuing Employees with a level of base pay that is no less than each Continuing Employee’s current salary or wage rate and with benefits and other compensation arrangements generally provided to Buyer’s employees at the time of Closing, subject to the terms and conditions of this Section 8.4. If a Transition Employee continues his/her employment with Buyer or one of its Affiliates (including the Acquired Companies) and is not terminated at the end of the Transition Period, then, for purposes of this Section 8.4(a), such Transition Employee shall be considered a “Retained Employee” effective as of the first day after the end of the Transition Period.

(b) The Continuing Employees will not accrue any additional benefits under Seller Employee Benefit Plans for periods after the Closing Date. Buyer shall not assume any Seller Employee Benefit Plans and shall have no obligations or liabilities under or with respect to any Seller Employee Benefit Plans.

(c) Each Continuing Employee shall become eligible to participate in the group health plan of Buyer or one of its Affiliates effective as of the Closing Date without any waiting period. With respect to any group health plan or program of Buyer or Buyer’s Affiliates in which a Continuing Employee becomes eligible to participate as of the Closing Date or thereafter, Buyer or one of its Affiliates shall cause each such Continuing Employee to (i) receive credit for any deductibles, co-pays or other out-of-pocket expenses paid under the corresponding Seller Employee Benefit Plan, and (ii) not be subject to any pre-existing condition limitations to the extent that such pre-existing condition limitation did not apply to such Continuing Employee under the corresponding Seller Employee Benefit Plan.

(d) Buyer or one its Affiliates shall credit each Continuing Employee with the same number of years of service, including partial years of service, as the Continuing Employee is credited with by Seller (or any other employer service that was previously recognized by Seller), under the applicable corresponding benefit plan sponsored by Buyer or its Affiliates. The service credit required by this Section 8.4(d) shall apply for all purposes under any health, severance, vacation, sick or any similar paid-time off program or other employee welfare benefit plan (as such term is defined in Section 3(1) of ERISA) of Buyer or its Affiliates and for purposes of eligibility to participate, vesting, eligibility for a particular form or type of benefit, and benefit accrual (except for benefit accrual under a defined benefit pension plan and vesting under a 401(k) plan or other defined contribution pension plan) under any pension, retirement, savings, or other employee pension benefit plan (as such term is defined in Section 3(2) of ERISA) of Buyer or its Affiliates. Continuing Employees will vest under the Buyer 401(k) Plan as specified in the Buyer 401(k) Plan.

(e) Claims for long-term disability benefits, short-term disability benefits, and workers’ compensation benefits arising out of occurrences prior to the Closing Date shall be the responsibility of Seller. Claims for long-term disability benefits, short-term disability benefits, and workers’ compensation benefits for Continuing Employees arising out of occurrences on or subsequent to the Closing Date shall be the responsibility of Buyer and its Affiliates (including, as applicable, the Acquired Companies).

(f) Seller shall retain all liability for severance and other benefits (including any notice obligations and liability arising under the WARN Act) to all employees of either

Acquired Company (including any Retained Employees and any Transition Employees) who are terminated on or prior to the Closing Date.

(g) Buyer and the Acquired Companies shall be liable for severance and other benefits, including any liability arising under the WARN Act, to any Continuing Employee whose employment is terminated after the Closing Date. If any Transition Employee’s employment is terminated (i) prior to the end of the Transition Period by Buyer or its Affiliates (including the Acquired Companies) without “cause” or by the Transition Employee for “good reason,” in each event using definitions that are identical to those provided under the ERT Transition Bonus Plan, or (ii) at the expiration of the Transition Period, such eligible Transition Employees will receive, conditioned upon the submission of an effective release of claims satisfactory to Buyer, (A) the transition bonus equal to 6 month’s salary payable under the ERT Transition Bonus Plan, (B) a severance payment equal to 2 week’s salary for each year of ERT service up to 20 weeks, and (C) if the eligible employee elects COBRA coverage, up to six months (or such shorter period during which COBRA coverage continues) of payments equal to the difference between the monthly COBRA premium for the coverage elected and the premium for such coverage that is payable by similarly-situated active employees. With respect to any such terminated Transition Employee, in the event that the sum of (x) all of the payments described in clauses (A) through (C), (y) the 2011 LTI payment, if any, and (z) the 2012 short term incentive bonus, if any (collectively the “Severance Payments” ), do not equal one year’s base salary of the terminated individual, a make-up payment will be made to make the aggregate total Severance Payments equal one year’s base salary. All Severance Payments shall be made in accordance with the terms of the applicable plan documents and applicable Law (including section 409A of the Code) and will be documented in writing at the time of termination. In the event that a Retained Employee is terminated by Buyer and its Affiliates (including the Acquired Companies) during the twelve (12) month period immediately following the Closing Date (or, in the case of a Transition Employee who continues in employment with Buyer and its Affiliates (including the Acquired Companies) after the end of the Transition Period, during the period beginning on the date after the last day of the Transition Period and ending twelve (12) months immediately after the Closing Date) for reasons other than cause, such individual shall also receive the Severance Payments described above for Transition Employees.

(h) To the extent properly included in Effective Time Net Working Capital, on the Closing Date or on such other dates provided under the change in control agreements (the “Change in Control Agreements”) and the ▇▇▇▇ ▇▇▇▇▇▇▇ Bonus Agreement and 2014 Stretch Bonus Agreements (together, the “Stretch Bonus Agreements”) listed on Schedule 4.2(n)(ix), Buyer shall cause the Acquired Companies to make the payments that are due under the Change in Control Agreements and Stretch Bonus Agreements (which amounts are set forth on Schedule 4.2(n)(ix)).

(i) To the extent properly included in Effective Time Net Working Capital, after Closing, Buyer shall, or shall cause one of its Affiliates (including the Acquired Companies) to, pay to all Continuing Employees any payments due to such Continuing Employees under the 2011 LTI, to the extent such payments were not previously paid to the Continuing Employees pursuant to the 2011 LTI’s terms. To the extent properly included in Effective Time Net Working Capital, Buyer shall, or shall cause one of its Affiliates (including the Acquired Companies) to, pay to all Continuing Employees any payments due to such Continuing

Employees under the 2012 LTI, and Buyer will provide Seller with an accounting of the payments made pursuant to the 2012 LTI within seven (7) days of payment, and Buyer shall reimburse Seller (or its designated Affiliate) for fifty percent (50%) of any 2012 LTI payments that are not paid to the Continuing Employees pursuant to the terms of the 2012 LTI by wire transfer of immediately available funds to an account designated in writing by Seller. To the extent properly included in Effective Time Net Working Capital, Buyer shall, or shall cause one of its Affiliates to, pay to all Continuing Employees who remain continuously employed by Buyer or one of its Affiliates (including the Acquired Companies) through the last day of the Transition Period the bonuses listed on Schedule 8.4(i) pursuant to the terms of the ERT Transition Bonus Plan (the “Transition Bonus”). Buyer will provide Seller with an accounting of the payments made pursuant to the Transition Bonus within seven (7) days of payment, and Buyer shall reimburse Seller (or its designated Affiliate) for fifty percent (50%) of any Transition Bonus that is not paid to a Continuing Employee in accordance with such schedule by wire transfer of immediately available funds to an account designated in writing by Seller. To the extent properly included in Effective Time Net Working Capital, Buyer shall, or shall cause one of its Affiliates (including the Acquired Companies) to, pay to all Continuing Employees any payments due to such Continuing Employees under the 2012 Bonus Plan in accordance with the terms of the 2012 Bonus Plan to the extent such payments were not previously paid to the Continuing Employees pursuant to the 2012 Bonus Plan. Buyer will provide Seller with an accounting of the payments made pursuant to the 2012 Bonus Plan within seven (7) days of payment, and Buyer shall reimburse Seller (or its designated Affiliate) for sixty-seven percent (67%) of any accrued bonus amounts that are not paid to the Continuing Employees pursuant to the terms of the 2012 Bonus Plan by wire transfer of immediately available funds to an account designated in writing by Seller. For the avoidance of doubt, payments under the 2011 LTI, 2012 LTI, Transition Bonus and 2012 Bonus Plan shall include those amount of related taxes and fees paid by the Company to a Governmental Authority.

(j) Except as provided in the Transition Services Agreement, Seller and its Affiliates (other than the Acquired Companies) shall be responsible for compliance with and liability under COBRA with respect to any COBRA-qualifying events that occur on or prior to the Closing Date to the extent mandated by COBRA, including with respect to the Continuing Employees and their dependents. Buyer and the Company shall be responsible for compliance with and liability under COBRA with respect to any COBRA-qualifying events that occur after the Closing Date with respect to the Continuing Employees who become covered under Buyer’s group health plan, and with respect to the dependents of such Continuing Employees. For purposes of this Section 8.4(j), COBRA also includes liabilities for continuation coverage under applicable state law.

(k) As soon as administratively practicable following the Closing Date for each Retained Employee, Buyer shall cause its 401(k) Plan (the “Buyer 401(k) Plan”) to accept direct rollovers of distributions to the applicable Retained Employee from the Helix 401(k) Employees Retirement Savings Plan (the “Helix 401(k) Plan”), including plan loans. With respect to each Retained Employee who elects a direct rollover to the Buyer 401(k) Plan, Seller shall cause the trustee of the Helix 401(k) Plan to roll over the distribution that the Retained Employee elects to roll over to the Buyer 401(k) Plan (the “Helix 401(k) Rollover”). The Helix 401(k) Rollover shall be made in cash or in cash equivalents or, with respect to outstanding loans to the Retained Employees, promissory notes. For purposes of clarity, such rollovers shall not involve the transfer of any employer securities between such plans. Seller, Buyer and the Acquired

Companies shall each reasonably cooperate with the other and shall provide to the other such written documentation, information and assistance as is reasonably necessary to effect the provisions of this Section 8.4(k).

(l) Nothing in this Section 8.4, whether express or implied, shall (i) be deemed to restrict the ability of Buyer or its Affiliates (including the Acquired Companies) to terminate the employment of any Continuing Employee after the Closing Date; (ii) confer upon any Person whether or not a party to this Agreement (including any Continuing Employee) any right to employment or recall, any right to continued employment, any right to compensation or benefits, or any other right of any kind or nature whatsoever, or (iii) constitute or be deemed to constitute an amendment of Employee Benefit Plan.

(m) Seller shall retain all liability associated with (i) the one-time payment referenced in Item 2 of Schedule 8.1(e)(iii) upon consummation of the transactions contemplated hereby and (ii) the payments referenced in Item 1 of Schedule 4.2(n)(v), and Seller shall indemnify and hold harmless Buyer and the Acquired Companies and their respective Representatives from and against any and all liabilities, losses, damages, claims, costs or expenses suffered or incurred by any of them in connection with such one-time payment referenced in Item 2 of Schedule 8.1(e)(iii) and such payments referenced in Item 1 of Schedule 4.2(n)(v).

Section 8.5 Public Announcements. Prior to the Closing Date, without the prior written approval of the other Party, which approval shall not be unreasonably withheld, neither Party will issue, or permit any agent or Affiliate of it to issue, any press releases or otherwise make, or cause any agent or Affiliate of it to make, any public statements with respect to this Agreement and the transactions contemplated hereby, except where such release or statement is deemed in good faith by the releasing Party to be required by Law or under the rules and regulations of the New York Stock Exchange (or other public stock exchange of similar reputation and standing) on which the shares of such Party or any of its Affiliates are listed. In each case to which such exception applies, the releasing Party will use its commercially reasonable efforts to consult with the other Party prior to issuing such release or statement prior to releasing or making the same.

Section 8.6 Amendment of Schedules. As of the Closing Date, all Schedules hereto shall be deemed amended and supplemented to include reference to any matter that results in an adjustment to the Purchase Price pursuant to Section 3.1. Seller shall update the Schedules to supplement or amend the Schedules (including the addition of schedules that are responsive to the representations and warranties contained herein but for which no schedule is contemplated as of the date hereof), in each case to reflect matters first occurring or initially arising following the date hereof that, if existing as of the date hereof, would have been required to be set forth in the Schedules (such updates, the “Schedules Updates”). Seller shall promptly deliver such Schedules Updates to Buyer. Notwithstanding any other provision of this Agreement, any disclosure in any of the Schedules Updates shall not be deemed to have cured any inaccuracy in or the breach of any representation or warranty contained in this Agreement or in Seller’s Closing Certificate for the purpose of the indemnification rights in Article 13, the termination rights in this Agreement or of determining whether or not the conditions set forth in Section 9.2(a) have been met.

Section 8.7 Parties Efforts and Further Assurances. Seller and Buyer each agree that from time to time after the Closing Date, each of them will execute and deliver or cause their respective Affiliates to execute and deliver such further instruments, and take (or cause their respective Affiliates to take) such other action, as may be necessary to carry out the purposes and intents of this Agreement.

Section 8.8 Reserved.

Section 8.9 Removal. Within a reasonable period of time following the Closing, and in any event within ninety (90) days thereof, Buyer shall and shall cause the Company to remove the name and ▇▇▇▇ of Seller and any of its Affiliates (other than the Acquired Companies) and any variations and derivatives thereof and logos relating thereto from the Assets.

Section 8.10 Books and Records. At Closing, Seller shall deliver the books and records of the Acquired Companies to Buyer at Seller’s offices in Houston, Texas. Buyer agrees to maintain all books and records of the Acquired Companies until the fifth (5th) anniversary of the Closing Date (or for such longer period of time as Seller shall advise Buyer is necessary in order to have the books and records of the Acquired Companies available with respect to open years for Tax audit purposes). Buyer shall provide Seller and its representatives reasonable access to and the right to copy the books and records of the Acquired Companies, but only as in existence as of the Closing Date, for the purposes of (a) preparing and delivering any accounting provided for under this Agreement and adjusting, prorating and settling the charges and credits provided for in this Agreement, (b) complying with any applicable Law or the prosecution or defense of any Action affecting Seller’s interests in the Purchased Equity and Assets prior to the Closing Date, (c) conducting and preparing any audit of the books and records of any third Person relating to Seller’s interest in the Purchased Equity and Assets prior to the Closing Date, or responding to any audit conducted or prepared by such third parties, (d) preparing Tax Returns, (e) responding to or disputing any Tax audit or (f) asserting, defending or otherwise dealing with any claim or dispute under this Agreement or with respect to the Assets or the Purchased Equity but only insofar as Buyer may do so without, in its good faith opinion, breaching or risking a breach of agreements with other Persons or waiving or risking waiving legal privilege of either Acquired Company or Buyer; provided, however, that Buyer shall, at Seller’s request and at no cost or expense to either Acquired Company or Buyer, request waivers of such confidentiality restrictions. In no event shall Buyer or any of its Affiliates destroy any books and records of either Acquired Company without giving Seller sixty (60) days’ advance written notice thereof and the opportunity, at Seller’s expense, to obtain such books and records prior to their destruction.

Section 8.11 Casualty and Condemnation. Subject to the Parties’ ability to exercise their rights provided in Sections 9.1(e)(ii) and 9.2(e)(ii), in the event of a Casualty Loss, to the extent insurance proceeds, condemnation awards or other payments are not committed, used or applied by Seller prior to the Closing Date to repair, restore or replace such damaged or taken Assets, Seller shall at the Closing (a) pay to Buyer all insurance, condemnation proceeds, awards and payments theretofore paid to Seller by reason of such Casualty Loss, less any reasonable costs and expenses, including any deductible, incurred by Seller in collecting same or in connection with such proceedings or the threat thereof promptly upon receipt. Any insurance, condemnation proceeds, awards and payments (or any rights thereto) by reason of a Casualty

Loss that are held by or owed to Seller for the account or benefit of any third Person joint interest owners shall not be paid by Seller to Buyer pursuant to this Section 8.11 and shall instead be transferred to the successor operator or other Person responsible therefor pursuant to the terms of the applicable operating or other agreement. To the extent any Casualty Losses, individually or in the aggregate, exceed the insurance proceeds, condemnation awards and other payments arising from such Casualty Losses by more than $100,000, then the Purchase Price shall be reduced by an amount equal to such excess amount, provided, however, that Buyer may notify Seller prior to Closing that it is waiving all reductions in the Purchase Price with respect to any Casualty Losses, in which case subsection (ii) of the closing conditions set forth in Sections 9.1(e) and 9.2(e) shall be deemed to be satisfied. As soon as practicable, Seller shall submit a claim to its insurance providers with respect to any Casualty Loss that arises or occurs on or after the date hereof but in any event before the Closing Date.

Section 8.12 Financial Statements; Financing Cooperation.

(a) Seller acknowledges that Buyer and/or its Affiliates may be required to include statements of revenues and direct operating expenses and other financial information relating to the Acquired Companies in documents filed with the Securities and Exchange Commission by Buyer and/or its Affiliates pursuant to the Securities Act of 1933, as amended, and that such financial statements may be required to be audited and may need to comply with the requirements of a Registration Statement on Form S-1 under the Securities Act of 1933, as amended, and the rules set forth in Regulation S-X (the “Requisite Financial Statement Information”). From and after the Closing Date, Seller will use commercially reasonable efforts to assist Buyer in obtaining all financial information related to the Acquired Companies for periods ending on or prior to the Closing Date that is necessary to comply with the requirements of a Registration Statement on Form S-1 under the Securities Act of 1933, as amended, and the rules set forth in Regulation S-X. Buyer shall be responsible, and obligated to reimburse Seller, for all reasonable third Person costs and expenses incurred by Seller associated with obtaining the Requisite Financial Statement Information. Seller shall provide Buyer reasonable access during the normal business hours to such records (to the extent such information is available) and personnel of Seller and use commercially reasonable efforts to provide reasonable access during normal business hours to Seller’s accounting firm, in each case, as Buyer may reasonably request to enable Buyer, and its representatives and accountants, for the sole purpose of creating and auditing the Requisite Financial Statement Information.

(b) Seller will request its external audit firm to consent to the inclusion or incorporation by reference of the Requisite Financial Statement Information in any registration statement, report or other document of Buyer or any of its Affiliates to be filed with the Securities and Exchange Commission upon receipt of written notice from Buyer’s counsel that the Requisite Financial Statement Information is required to be included or incorporated by reference to satisfy any rule or regulation of the Securities and Exchange Commission or to satisfy relevant disclosure obligations under the Securities Act of 1933, as amended, or the Securities Exchange Act of 1934, as amended. Upon request of Buyer, Seller agrees to request the external audit firm that audits the Acquired Companies’ financial statements (the “Audit Firm”) to consent to the inclusion or incorporation by reference of its audit opinion with respect to the audited financial statements in any such registration statement, report or other document. Seller shall (i) provide Buyer and Buyer’s independent accountants with access to management

representation letters provided by Seller or the Acquired Companies (as the case may be) and use commercially reasonable efforts to provide access to Seller’s (or the Acquired Companies’, as the case may be) independent accountants and (ii) authorize Seller’s Audit Firm to provide such Audit Firm’s audit work papers to Buyer and Buyer’s independent accountants.

Section 8.13 Bonds and Guarantees.

(a) Buyer and Seller agree to work jointly together to obtain from BOEM the amount of a bond or bonds required to obtain from BOEM a full release of Seller from its financial guarantee to BOEM with respect to the obligations of the Acquired Companies and at Closing Buyer shall provide a bond or bonds in the amount so specified by BOEM, provided that if BOEM has not specified such amount at the time of Closing, then Buyer shall provide a bond or bonds to BOEM in the aggregate amount of $110,287,000 at or prior to Closing. If the release of Seller’s financial guarantee to BOEM is not obtained at Closing, Buyer shall (i) take all actions required by BOEM to obtain a complete release of Seller’s financial guarantee to BOEM, including without limitation, providing a supplemental bond or bonds to BOEM in additional amounts as specified by BOEM promptly, but in any event within thirty (30) days, after so specified by BOEM unless extended by mutual agreement of Buyer and Seller and (ii) cause the Acquired Companies not to drill any additional new ▇▇▇▇▇ until the earlier of (A) six (6) months following the Closing or (B) the release of Seller’s financial guarantee to BOEM. Notwithstanding the foregoing, Buyer shall be permitted to engage in recompletions and workovers on existing ▇▇▇▇▇. Until such time as Seller’s financial guarantee is released by BOEM, Buyer shall use commercially reasonable efforts to ensure BOEM seeks any damages first against the bonds provided by Buyer pursuant to this Section 8.13(a) prior to the guarantee by Seller, provided, that any rights that Buyer may have to indemnification pursuant to Section 13.2 shall not be prejudiced or affected thereby. In furtherance hereof and in addition to the foregoing, Buyer shall submit or cause to be submitted to BOEM the form(s) necessary to accomplish the foregoing, including Form BOEM-2028A attached hereto as Exhibit 8.13(a) with the second box checked as reflected on such exhibit.

(b) The Parties understand that none of the bonds, letters of credit and guarantees, if any, posted by Seller or any Affiliate of Seller (including the Acquired Companies to the extent Seller or its Affiliates (except the Acquired Companies) provide credit support for any such bonds, letters of credit or guarantees) with any Governmental Authority or third Person and relating to the Assets are to be transferred to Buyer. Within thirty (30) days following the Closing Date and each anniversary of the Closing Date, Buyer will pay to Seller a fee in an amount equal to 1.5% of the aggregate estimated plugging and abandonment costs, as set forth on Schedule 8.13(b)(i), of the ▇▇▇▇▇, platforms, facilities, pipelines and other Assets set forth on Schedule 8.13(b)(i) that (i) have not been permanently plugged and abandoned consistent with past practice prior to the date of such payment and (ii) with respect to which all of the Unreleased Financial Guarantees of Seller have not been completely released and discharged. Schedule 8.13(b)(ii) identifies the ▇▇▇▇▇, platforms, facilities, pipelines and other Assets of the Acquired Companies that the Acquired Companies are obligated to plug and abandon, together with the estimated cost to complete such plugging and abandonment. For the avoidance of doubt, (x) Buyer shall no longer have any obligation to pay the fee described in this Section 8.13(b) with respect to the estimated costs of plugging and abandonment of ▇▇▇▇▇, platforms, facilities, pipelines and other Assets that have been plugged and abandoned or with

respect to which all of the Unreleased Financial Guarantees of Seller have been completely released and discharged and (y) the estimated aggregate plugging and abandonment costs shall be reduced to the extent the plugging and abandonment costs for a particular well, platform, facility, pipeline or other Asset have been reduced as a result of a temporary abandonment of such well, platform, facility, pipeline or other Asset. Notwithstanding anything to the contrary herein, all obligations of Buyer to pay the fee described in this Section 8.13(b) shall terminate and be without further effect at such time as the aggregate estimated plugging and abandonment costs of the ▇▇▇▇▇, platforms, facilities, pipelines and other Assets set forth on Schedule 8.13(b)(i) that have not been plugged and abandoned or with respect to which all of the Unreleased Financial Guarantees of Seller have not been completely released and discharged is less than $50,000,000.

(c) Schedule 4.2(ff) identifies the bonds and letters of credit and other forms of financial assurance posted (or supported) by Seller, the Acquired Companies or any other Affiliate of the Company with respect to the Assets that will be in effect immediately prior to the Closing. Buyer shall (i) obtain or cause to be obtained in the name of Buyer, replacements for the bonds, letters of credit and other forms of financial assurance identified on Schedule 8.13(c) and (ii) cause, effective as of the Closing, the cancellation or return to Seller of such bonds, letters of credit or other forms of financial assurance, and Seller shall provide reasonable cooperation to Buyer in connection therewith. Buyer may also provide evidence that such replacements are not necessary as a result of existing bonds, letters of credit or other forms of financial assurance that Buyer has previously posted as long as such existing bonds, letters of credit or other forms of financial assurance are adequate to secure the release of those posted (or supported) by Seller. With respect letters of credit identified on Schedule 8.13(c) outstanding under any Loan that relate to either of the Acquired Companies or the Assets, Buyer shall take such action to replace, cash collateralize or provide third Persons backstops so as to enable the Lien Release to be delivered at Closing. Notwithstanding anything to the contrary herein, no Acquired Company shall be responsible for any collateral currently provided by Seller under any shared insurance program.

(d) If Seller or its Affiliates (including the Acquired Companies to the extent Seller or its Affiliates (except the Acquired Companies) provide credit support for any bonds, letters of credit or guarantees) are not released at or prior to Closing from one or more of the bonds, letters of credit and guarantees posted by Seller or any Affiliate of Seller with any third Person and relating to the Assets (the “Unreleased Financial Guaranties”), Buyer shall, and shall cause the Company to, at Closing, execute and deliver to Seller for the benefit of Seller and its Affiliates (to the extent Seller and such Affiliates are obligors under the Unreleased Financial Guaranties (the “Obligors”)) an indemnity agreement in the form attached hereto as Exhibit 8.13(d) (the “Indemnity Agreement”) pursuant to which Buyer and the Acquired Companies agree to indemnify the Obligors from and against all of their obligations arising under the Unreleased Financial Guaranties except to the extent such obligations are otherwise subject to Section 13.2. No such provision of an indemnity agreement shall relieve Buyer or the Company or any other Person providing an indemnity, guarantee, or other form of surety or security of its obligations thereunder. Buyer agrees that Seller will not have an adequate remedy at Law if Buyer or an Acquired Company violates (or threatens to violate) any of the terms of this Section 8.13(d). In such event, Seller shall have the right, in addition to any other they may have, to obtain injunctive relief to restrain any breach or threatened breach of the terms of this Section 8.13(d).

Section 8.14 Third Party Approvals. Buyer and Seller shall (and shall each cause their respective Affiliates to) use commercially reasonable efforts to obtain all consents and approvals from, and make all filing with, any Person that any of Buyer and Seller or their respective Affiliates are required to obtain in order to consummate the transactions contemplated hereby, including the BOEM and other applicable Governmental Authorities that may be required under the terms of (or regulations specifically applicable to) any leases in connection with the transactions contemplated hereby.

Section 8.15 Tax Matters.

(a) Tax Sharing Agreements. Effective as of the Effective Time (in respect of Non-Income Taxes) and the Closing Date (in respect of Income Taxes), any tax-sharing, indemnity, allocation or similar agreement between or among Seller, either Acquired Company or any of its Affiliates shall be terminated and shall have no further effect for any taxable period (whether the current period, a future period, or a past period).

(b) Filing of Tax Returns; Payment of Taxes.

(i) Subject to Section 8.15(b)(ii), the Buyer shall prepare or cause to be prepared all Tax Returns of each Acquired Company required to be filed after the Closing Date for all Pre-Closing Tax Periods, Pre-Effective Time Tax Periods, Straddle Income Tax Periods and Straddle Non-Income Tax Periods. Such Tax Returns shall be prepared on a basis consistent with past practice except to the extent otherwise required by applicable Law. The Buyer shall deliver a copy of such Tax Return, together with all supporting documentation and workpapers, to the Seller for its review not later than forty-five (45) days before the date on which the Tax Return is due to be filed (taking into account any valid extensions) (the “Due Date”) (or, in the case of ad valorem property Taxes, within thirty (30) days of receipt of the ▇▇▇▇ for such ad valorem property Taxes) or, in the case of any such Tax Returns due within sixty (60) days after the Closing Date, as soon as reasonably practicable. Buyer shall not file such Tax Return or cause such Tax Return to be filed until the earlier of either the receipt of written notice from Seller indicating Seller’s consent thereto, or the Due Date. If Seller disputes any item on such Tax Return, the Seller shall notify Buyer of such disputed item (or items) and the basis for its objection. The Parties shall act in good faith to resolve any such dispute prior to the date on which such Tax Return is required to be filed. If the Parties cannot resolve any disputed item, the item in question shall be resolved by an independent accounting firm mutually acceptable to Seller and Buyer. The fees and expenses of such accounting firm shall be borne equally by Seller and Buyer. The Buyer will cause such Tax Return to be timely filed and will provide a copy to the Seller. Not later than five days prior to the due date for payment of Taxes with respect to any Tax Return for a Pre-Closing Tax Period, Pre-Effective Time Tax Period, Straddle Income Tax Period or Straddle Non-Income Tax Period, the Seller shall pay to the Buyer the amount of any Seller Taxes with respect to such Tax Return.

(ii) With respect to each Tax Return relating to Income Taxes that is required to be filed after the Closing Date for, by or with respect to any consolidated, combined or unitary group of which either Acquired Company is a member (but the parent thereof is

not an Acquired Company), Seller shall cause such Tax Return to be prepared and shall cause such Tax Return to be timely filed with the appropriate Governmental Authority and pay timely the amount of Taxes shown to be due on such Tax Return. Such Tax Returns shall be prepared on a basis consistent with past practice except to the extent otherwise required by applicable Law.

(iii) Whenever it is necessary for purposes of this Agreement to determine the portion of any Taxes of or with respect to either Acquired Company for a Straddle Income Tax Period which is allocable to the Pre-Closing Tax Period or the Post-Closing Tax Period or for a Straddle Non-Income Tax Period which is allocable to the Pre-Effective Time Tax Period or the Post-Effective Time Tax Period, as the case may be, the determination shall be made as if each Acquired Company was not a member of Seller’s consolidated, affiliated, combined or unitary group for Tax purposes. Any Income Taxes attributable to a Straddle Income Tax Period will be allocated between the Pre-Closing Tax Period and the Post-Closing Tax Period based on an interim closing of the books (such Taxes allocable to the Pre-Closing Tax Period being determined as if such taxable period ended as of the Closing Date). Any Non-Income Taxes attributable to a Straddle Non-Income Tax Period will be allocated between the Pre-Effective Time Tax Period and the Post-Effective Time Tax Period based upon the number of days in the applicable period falling on or before, or after, November 30, 2012. To the extent necessary, Seller shall estimate Taxes based on Seller’s liability for Taxes with respect to the same or similar Tax item in the immediately preceding taxable period. Notwithstanding anything to the contrary herein, (i) any franchise Tax paid or payable with respect to either Acquired Company shall be allocated to the taxable period during which the income, operations, assets or capital comprising the base of such Tax is measured, regardless of whether the right to do business for another taxable period is obtained by the payment of such franchise Tax, (ii) any ad valorem or property Taxes paid or payable with respect to the Assets shall be allocated to the taxable period applicable to the ownership of the Assets regardless of when such Taxes are assessed and (iii) any severance, production and similar Taxes based upon or measured by the quantity of or the value of the production of Hydrocarbons shall be apportioned between Seller and Buyer based on the number of units or value of production actually produced and subject to Tax, as applicable, on or before, and after, November 30, 2012 and any such Taxes shall be deemed attributable to the period during which the relevant production occurred.

(c) Audits. Seller shall not settle any audit of any Seller consolidated federal income Tax Return to the extent that such Tax Return relates to either Acquired Company in a manner that would materially adversely affect either Acquired Company after the Closing Date unless such settlement would be reasonable in the case of a Person that owned the Acquired Companies both before and after the Closing Date.

(d) Contest Provisions.

(i) From and after Closing, each of Buyer, on the one hand, and Seller, on the other hand (the “Tax Indemnified Person”), shall notify the chief tax officer (or other appropriate person) of Seller or Buyer, as the case may be, in writing within fifteen (15) days of receipt by the Tax Indemnified Person of written notice of any pending or

threatened audits, adjustments, claims, examinations, assessments or other proceedings with respect to either Acquired Company (a “Tax Audit”) which are likely to affect the liability for Taxes of such other Party. If the Tax Indemnified Person fails to give such timely notice to the other Party, it shall not be entitled to indemnification for any Taxes arising in connection with such Tax Audit to the extent such failure to give timely notice actually and materially adversely affects the other Party.

(ii) If such Tax Audit relates solely to Seller Taxes, Seller shall, at its expense, conduct and control the defense and settlement of such Tax Audit, but Buyer shall have the right to participate in such Tax Audit at its own expense, and Seller shall not be able to settle, compromise and/or concede any portion of such Tax Audit that is reasonably likely to affect the Tax liability of Buyer or either Acquired Company for any Post-Closing Tax Period without the consent of Buyer, which consent shall not be unreasonably withheld, delayed or conditioned; provided, that if Seller fails to assume control of the conduct of any such Tax Audit within a reasonable period following the receipt by Seller of notice of such Tax Audit, Buyer shall have the right to assume control of such Tax Audit and shall be able to settle, compromise and/or concede such Tax Audit in its sole discretion. If such Tax Audit relates to Seller Taxes and Taxes other than Seller Taxes, Buyer shall control the conduct of such Tax Audit, but Seller shall have the right to participate in such Tax Audit at its own expense, and Buyer shall not settle, compromise and/or concede such Tax Audit without the consent of Seller, which consent shall not be unreasonably withheld, delayed or conditioned. If such Tax Audit relates solely to Taxes which are not Seller Taxes, Buyer shall conduct and control the defense and settlement of such Tax Audit.

(iii) For the avoidance of doubt, this Section 8.15(d) and not Section 13.3 shall control the conduct of a Tax Audit.

(e) Cooperation. Buyer, the Acquired Companies and Seller shall cooperate fully, as and to the extent reasonably requested by the other Party, in connection with the filing of Tax Returns provided herein and any Tax Audit, litigation or other proceeding with respect to Taxes. Such cooperation shall include the retention and (upon the other Party’s request) the provision of records and information that are reasonably relevant to any such audit, litigation or other proceeding and making employees available on a mutually convenient basis to provide additional information and explanation of any materials provided hereunder. Buyer and Seller agree (i) to retain all books and records with respect to Tax matters pertinent to either Acquired Company relating to any taxable period beginning before the Closing Date until the expiration of the statute of limitations (and, to the extent notified by Buyer or Seller, any extension thereof) applicable to the taxable period to which such books and records relate or until the final determination of any controversy with respect to such taxable period, and to abide by all record retention agreements entered into with any taxing authority, and (ii) to give the other Party reasonable written notice prior to transferring, destroying or discarding any such books and records and, if the other Party so requests, the Buyer or the Seller, as the case may be, shall allow the other Party to take possession of such books and records. Buyer and Seller further agree, upon request, to use their best efforts to obtain any certificate or other document from any Governmental Authority or any other Person as may be necessary to mitigate, reduce or

eliminate any Tax that could be imposed (including, but not limited to, with respect to the transactions contemplated hereby).

(f) Post-Closing Actions Which Affect Seller’s Tax Liability. Except to the extent required by applicable Laws, neither Buyer, on the one hand, nor Seller, on the other hand, shall and they shall not permit their respective Affiliates, including the Acquired Companies, to amend any Tax Return of either Acquired Company with respect to Non-Income Taxes for a Pre-Effective Time Tax Period or Income Taxes for a Pre-Closing Tax Period without the prior written consent of the other (such consent not to be unreasonably withheld, delayed or conditioned) if such amended Tax Return would materially increase the amount of Taxes for which the other Party is responsible.

(g) Section 754 Election. Seller shall, prior to the Closing, (i) cause each Asset that is classified as (or treated as being held by) a tax partnership for federal income tax purposes to either (x) have in effect an election under Section 754 of the Code for any taxable year that includes the date of the Closing or (y) obtain all necessary consents therefor; and (ii) provide evidence satisfactory to Buyer that the covenants set forth in clause (i) have been satisfied.

(h) Refunds. Buyer agrees to pay to Seller any Tax refund received, together with any interest thereon, from a Governmental Authority after the Closing by Buyer or its Affiliates, including either Acquired Company in respect of any Non-Income Taxes of either Acquired Company for a Pre-Effective Time Tax Period and any Income Taxes of either Acquired Company for a Pre-Closing Tax Period (in both cases, other than any refund resulting from the carryback of a net operating loss or other Tax attribute from a period beginning after the Closing Date to a period ending on or before the Closing Date, which refund shall be for the account of Buyer) to the extent not taken into account in determining the Effective Time Net Working Capital. Any such refund received by Buyer, its Affiliates, or an Acquired Company shall be paid to Seller within thirty (30) days after such Tax refund is received. Buyer agrees to notify Seller within ten (10) days upon receipt of any such Tax refund. Buyer shall be entitled to any refund received (whether by payment, credit, offset or otherwise, and together with any interest thereon), with respect to or relating to either Acquired Company, other than those to which Seller is entitled pursuant to this Section 8.15(h).

(i) Conversion; Allocation.

(i) Notwithstanding anything to the contrary herein, at least one (1) Business Day prior to the Closing Date, Seller shall cause each Acquired Company to convert to a Delaware limited liability company in accordance with Section 18-214 of the Delaware Limited Liability Company Act (“Conversion”), and each shall become a disregarded entity for United States federal Tax purpose and corresponding state income Tax Laws. Accordingly, the Parties intend for federal income Tax purposes and for relevant state income Tax purposes that (i) each Acquired Company that is currently classified as a corporation for federal Tax purposes will be treated as completely liquidated in a nontaxable transaction pursuant to Sections 332 and 337 of the Code, (ii) the purchase and sale hereunder of the Purchased Equity following Conversion will be treated as a taxable sale by Seller of the Assets to Buyer, and the purchase of such Assets by Buyer from Seller, for the applicable portion of the Purchase Price and the assumption of

liabilities allocable to the Purchased Equity and (iii) this Agreement is a plan of complete liquidation of each of the Acquired Companies that is classified as a corporation for United States federal income tax purposes pursuant to Section 332 of the Code. The Parties agree not to take any position inconsistent with such intended Tax consequences.

(ii) Since the purchase and sale of the Purchased Equity following the Conversion is intended to be treated as the purchase and sale of the underlying Assets for federal income tax purposes, the parties agree that Schedule 8.15(i)(ii) sets forth a schedule allocating the Purchase Price plus the liabilities of the Acquired Companies among the Assets in a manner that complies with Section 1060 of the Code and the Treasury Regulations promulgated thereunder (the “Allocations”). Seller and Buyer agree to amend Schedule 8.15(i)(ii) to reflect any adjustments to the Purchase Price. The Allocations, as adjusted, shall be final and binding on the Parties (and their respective Affiliates) for all Tax purposes and the Parties shall file all Tax Returns (including IRS Form 8594) in a manner consistent with such Allocations. The Parties shall not take nor permit their Affiliates to take any position inconsistent with such Allocations unless otherwise required by Law.

(j) Transfer Taxes. All transfer, documentary, sales, use, stamp, registration and other such Taxes, and all conveyance fees, recording charges and other fees and charges (including any penalties and interest) (“Transfer Taxes”) incurred in connection with consummation of the transactions contemplated by this Agreement shall be paid equally by Buyer and Seller when due, and Buyer will cause each Acquired Company to, at Buyer’s own expense, file all necessary Tax Returns and other documentation with respect to all such Transfer Taxes, fees and charges, and, if required by applicable Law, Seller will, and will cause its Affiliates to, join in the execution of any such Tax Returns and other documentation.

(k) No Duplication. Notwithstanding anything to the contrary in this Section 8.15 and Article 13, (i) Seller shall not have any liability for, and shall not be required to pay to Buyer, any amounts pursuant to this Section 8.15 or Article 13 in respect of any Taxes to the extent such Taxes were taken into account in determining the Effective Time Net Working Capital and (ii) Buyer shall not have any liability for, and shall not be required to pay to Seller, any amounts pursuant to this Section 8.15 or Article 13 in respect of any Taxes to the extent such Taxes were taken into account in determining an increase to the Purchase Price described in Section 3.1(c).

(l) Conflict. In the event of a conflict between the provisions of this Section 8.15 and any other provision of this Agreement, this Section 8.15 shall control.

Section 8.16 Intercompany Indebtedness. At or prior to Closing, (a) Seller shall, and shall cause its Affiliates (other than the Acquired Companies) to, extinguish (without the payment of cash) any Loans (together with all accrued and unpaid interest thereon) owing by either Acquired Company to Seller or any of its Affiliates (other than the Acquired Companies) and (b) Seller shall cause the Acquired Companies to extinguish (without the payment of cash) any Loans (together with all accrued and unpaid interest thereon) owing by Seller or any Affiliate to either Acquired Company. For the avoidance of doubt, (i) all such Loans shall be extinguished on or prior to the Closing with no amounts remaining outstanding, due or owing immediately following the Closing, (ii) no amounts with respect to any such Loans or the

elimination thereof shall be included in the calculation of Effective Time Net Working Capital, (iii) no adjustment shall be made to the Purchase Price with respect to any such Loans or the elimination thereof and (iv) no payments shall be made with respect to any such Loans or the elimination thereof.

Section 8.17 Hedge Novation. Prior to the Closing, Seller shall use commercially reasonable efforts to obtain the consent of the each of the counterparties to the Product Hedging Contracts to which an Acquired Company is a party to be novated to the Seller or one of its Affiliates (other than an Acquired Company) as of Closing. In the event that any Product Hedging Contract to which an Acquired Company is a party cannot be novated to Seller or one of its Affiliates (other than an Acquired Company) prior to the Closing, each such Product Hedging Contract shall be closed-out, terminated, expired or otherwise settled prior to or as of the Closing. The Purchase Price shall be increased by the fair market value of each such Product Hedging Contract, if positive, or decreased by the absolute value of the fair market value of each such Product Hedging Contract, if negative. For purposes of determining the adjustments to the Purchase Price for Product Hedging Contracts that are not novated but that are closed-out, terminated, expired or otherwise settled at or prior to Closing, the adjustments shall be equal to the fair market value at the time such Product Hedging Contract was closed-out, terminated, expired or otherwise settled.

Section 8.18 P&A Costs.

(a) Set forth in Schedule 8.18 are the estimated plugging and abandonment costs (collectively, the “Scheduled P&A Costs”) required to be incurred by the Acquired Companies for either Acquired Company’s ▇▇▇▇▇, platforms, facilities and pipelines for the twelve (12) months immediately following the date that is forty-five (45) days after the date hereof (other than with respect to the South ▇▇▇▇▇ Island 130 property) (the “P&A Schedule”). In the event the Acquired Companies’ actual aggregate plugging and abandonment costs with respect to the ▇▇▇▇▇, platforms, facilities and pipelines set forth in the P&A Schedule during the twelve month period immediately following Closing (the “Actual P&A Costs”) exceed the Scheduled P&A Costs set forth in the P&A Schedule with respect to the ▇▇▇▇▇, platforms, facilities and pipelines set forth in the P&A Schedule during the twelve month period immediately following Closing (the “Estimated P&A Costs”) by more than five percent (5%), subject to the procedures and limitations set forth in Section 8.18(b) and (c) below, Seller shall pay Buyer the lesser of (i) the amount by which the Actual P&A Costs exceed 105% of the Estimated P&A Costs and (ii) $10,000,000.00 (such amount, the “P&A Excess Liability”).

(b) Notwithstanding anything set forth in Section 8.18(a) or (c), no amount of Actual P&A Costs shall be included in calculating whether the Actual P&A Costs exceed the Estimated P&A Costs if the plugging and abandonment work was performed by a vendor that was not mutually agreed upon in writing by Seller and Buyer prior to the commencement of such work; provided that Seller may not unreasonably withhold, condition or delay its agreement to a vendor identified by Buyer.

(c) Within thirty (30) days following the twelve-month anniversary of Closing, Buyer shall provide Seller with a statement (the “P&A Statement”) setting forth: (i) the total amount of Actual P&A Costs, (ii) a schedule showing the costs incurred in connection with each well,

platform, facility or pipeline and (iii) evidence of payment in connection with each well, platform, facility or pipeline. Buyer shall provide Seller with all invoices, receipts, reasonable access to personnel and such other assistance as may be reasonably requested by Seller to verify the P&A Statement. As soon as reasonably practicable but not later than the thirtieth (30th) day following receipt of the P&A Statement, Seller may deliver to Buyer an objection notice (a “P&A Objection Notice”) containing any objections Seller asserts with respect to the P&A Statement. Seller shall be deemed to have accepted and agreed to all items in the P&A Statement other than such matters that are proposed to be changed in the P&A Objection Notice. The Parties shall undertake to agree on the final Actual P&A Costs no later than the sixtieth (60th) day after delivery of the P&A Statement. If the final Actual P&A Costs are:

(i) mutually agreed upon in writing by Seller and Buyer during such sixty (60) day period or if Seller does not deliver a P&A Objection Notice within the thirty (30) day period, the final Actual P&A Costs shall be conclusive and binding on Buyer, the Company and Seller; or

(ii) not mutually agreed upon by Seller and Buyer during such sixty (60) day period, then the Accountant shall resolve any disagreements. The Accountant shall determine as promptly as practicable, but in any event within thirty (30) days after the matter is referred to the Accountant, based solely on written submissions provided by Buyer and Seller to the Accountant (and without independent investigation on the part of the Accountant) within ten (10) days following the date the matter is referred to the Accountant, whether and to what extent (if any) the P&A Statement requires adjustment. In resolving any disputed item, the Accountant shall act as an expert and not an arbitrator, and shall resolve only the items set forth in the P&A Objection Notice that are still in dispute and may not assign an expense to any item greater than the highest expense for such item claimed by either Party or less than the lowest expense for such item claimed by either Party. The fees and expenses of the Dispute Auditor shall be paid by the Parties in inverse proportion to the relative success of their claims. The determination of the Accountant shall be final, conclusive and binding on Buyer, the Company and Seller.

The date on which the final Actual P&A Costs are determined in accordance with this Section 8.18(c) is referred to as the “P&A Determination Date.” The P&A Excess Liability, if any, shall be paid by Seller to Buyer within five (5) Business Days of the P&A Determination Date by electronic transfer of immediately available funds to Buyer at the account set forth in Schedule 3.3(e), or to such other bank and account as may be specified by Buyer in writing.

Section 8.19 Insurance.

(a) Prior to the Closing, the Seller and its Affiliates (including the Acquired Companies) have maintained certain insurance policies (the “Seller Insurance Policies”) that provide property and liability insurance coverage with respect to the Acquired Companies and their respective businesses, Assets, employees, officers, directors, managers and members, all as defined in the respective Seller Insurance Policies (collectively, the “Acquired Company Insureds”). Except as otherwise provided in this Section 8.19, from and after the Closing Date: (i) Seller shall retain and have the sole responsibility for making any premium or other payments due under the Seller Insurance Policies, and Buyer and its Affiliates (including the Acquired

Companies) shall have no responsibility therefor; and (ii) Buyer and its Affiliates (including the Acquired Companies) shall be responsible in their sole discretion for maintaining their own insurance programs to provide coverage for Buyer, its Affiliates (including the Acquired Companies) and their respective businesses, assets (including the Assets), employees, officers, directors, managers and members.

(b) Each of the Buyer and Seller acknowledge that the Acquired Companies shall retain the benefit of each “occurrence”- based first-party Energy Package Policy and Commercial General Liability policy, which has been underwritten and/or issued by any Person (other than Seller or its Affiliates) under which either Acquired Company is an insured (hereinafter referred to as “Occurrence-Based Policies”) in relation to events occurring prior to Closing in respect of claims for which either Acquired Company may have coverage thereunder. Buyer acknowledges that, except as provided herein, any obligation of Seller to maintain the coverage provided under the Seller Insurance Policies for the Acquired Company Insureds will cease effective as of the Closing with respect to the Acquired Company Insureds for occurrences taking place after the Closing, and upon such termination, the Acquired Company Insureds will have to obtain replacement coverage with respect to occurrences taking place after the Closing.

(c) If required under the Occurrence-Based Policies, Seller shall, and shall cause its Affiliates to, collect all insurance proceeds in respect of any pre-Closing occurrences for which a claim is made under such policies and promptly (but in any event within five (5) business days after receipt thereof) remit any such proceeds paid to Seller or its Affiliates to Buyer If subsequent to the Closing Date, Seller or any of its Affiliates receives proceeds from an insurance claim made under an Occurrence-Based Policy, to the extent such proceeds represent reimbursement of losses of the Acquired Company Insureds in relation to events occurring prior to Closing, Seller shall, and shall cause its Affiliates to, promptly upon receipt, remit such proceeds to the Buyer, less any required deductible payment. Seller shall not be responsible for payment of any deductibles associated with any claim arising out of a pre-Closing occurrence for which the Acquired Company Insureds are otherwise entitled to receive the insurance proceeds under this Section 8.19.

(d) Notwithstanding the foregoing, Seller and Buyer shall, and shall cause each of their respective Affiliates to, cooperate with and use commercially reasonable efforts to, upon request, assist in the collection of proceeds from insurance claims made under any Occurrence-Based Policy. Without limiting the generality of the foregoing, Seller shall, and shall cause its Affiliates to, upon request, assert, or assist the Acquired Company Insureds in asserting claims in accordance with the terms of the Occurrence-Based Policies to the extent of the insurance coverage available thereunder with respect to the Acquired Company for periods prior to the Closing Date.

(e) Buyer shall promptly report to Seller any claims, to the Knowledge of Buyer, that are or may be covered by any Seller Insurance Policies and shall keep Seller reasonably informed with regard to the status thereof.

(f) Seller and Buyer shall cooperate in the investigation, defense and settlement of insurance claims under the Occurrence-Based Policies, in order to maximize insurance recoveries while respecting ongoing commercial relationships with the insurers involved.

(g) To the extent that an Occurrence-Based Policy may provide coverage to either Acquired Company for pre-Closing events, Seller agrees to maintain the Occurrence-Based Policies until July 1, 2013.

Section 8.20 Affiliate Agreements. At or prior to Closing, Seller (or an Affiliate of Seller, as applicable), on the one hand, and either Acquired Company (as applicable), on the other hand, shall terminate all Affiliate Transactions pursuant to termination agreements in form and substance reasonably acceptable to Buyer, other than those agreements set forth in Schedule 8.20 (the “Surviving Agreements”).

Section 8.21 Preferential Purchase Rights; Transfer Requirements.

(a) Promptly after the date hereof, Seller shall prepare and send (i) notices to the holders of any Transfer Requirements that are set forth in Schedule 4.2(p) requesting consents to the transactions contemplated by this Agreement and (ii) notices to the holders of any applicable Preference Rights that are set forth in Schedule 4.2(p) requesting waivers of such rights. Prior to Closing, Seller shall use its commercially reasonable efforts to cause such Transfer Requirements (and any fees payable in connection therewith) and waivers of Preference Rights (or the exercise thereof) to be obtained and delivered prior to Closing; provided, however, that Seller and its Affiliates shall not be required to make payments or undertake obligations to or for the benefit of the holders of such rights in order to obtain the Transfer Requirements (and any fees payable in connection therewith). In the event any Transfer Requirement is not obtained prior to Closing (or any fee payable has not been paid in connection therewith), Seller shall not be obligated to take any action that would result in a breach of any contract for which the Transfer Requirement has not been obtained (or any fee payable has not been paid in connection therewith) and will have the right to take such actions as are reasonably necessary to comply with the applicable contract. Following Closing, Buyer and the Company shall be the only parties responsible for obtaining such Transfer Requirement (and any fees payable in connection therewith).

(b) Should the holder of any Preference Right set forth in Schedule 4.2(p) validly exercise the same (whether before or after the Closing), then:

(i) Seller shall cause the Company or CKB, as applicable, as owner of the applicable asset, before Closing, and Buyer shall cause the Company or CKB, as applicable, as owner of the applicable asset, after Closing, to transfer such asset to the holder of the Preference Right on the terms and provisions set out in the applicable Preference Right provision; and

(ii) the Company or CKB, as applicable, shall be entitled to the consideration paid by such holder.

Section 8.22 Seismic Transfer.

(a) Schedule 8.22 sets forth all seismic, data and geophysical licenses and permits (each, a “Seismic License”) by which either Acquired Company is bound that would require the consent from the counterparty thereto and the payment of any amount as a result of the consummation of the transactions contemplated hereunder. Within ten (10) Business Days after

the date of this Agreement, Buyer shall notify Seller in writing with respect to each Seismic License whether it is to be (i) terminated and cancelled (the “Terminated Licenses”) or (ii) retained by either Acquired Company (the “Retained Licenses”). Prior to the Closing but after such ten (10) Business Day period, Seller shall, and Buyer shall assist Seller to, terminate and cancel all Terminated Licenses identified by Buyer. To the extent that (i) Buyer or either Acquired Company is required to pay any amount in connection with terminating and cancelling such Terminated Licenses or (ii) the Seller is unable to cancel and terminate such Terminated Licenses and Buyer or either Acquired Company is required to pay any transfer, assignment or change of control fees required under such Terminated Licenses in connection with the consummation of the transactions contemplated hereunder, the Purchase Price shall be reduced by an amount equal to the aggregate of all such amounts and fees paid by Buyer or either Acquired Company. Notwithstanding anything to the contrary herein, the Purchase Price shall not be reduced by any amounts paid by Seller that are attributable to buyouts for overriding royalties existing as of the Effective Time under any such Terminated Licenses.

(b) To the extent Buyer or either Acquired Company incurs any costs or expenses with respect to any seismic, data or geophysical licenses or permits as a result of the transactions contemplated by this Agreement that are not set forth on Schedule 8.22 and to which either Seller or any of its Affiliates were a party prior to the Closing, Seller shall pay all such costs and expenses and shall indemnify, defend, hold harmless and reimburse Buyer Indemnified Persons for all such costs and expenses.

(c) For each Retained License, the provisions of Section 8.22(a) shall not apply and the Purchase Price shall not be adjusted in any respect, including through the calculation of Effective Time Net Working Capital.

(d) For the avoidance of doubt, with respect to any Seismic License that is terminated or cancelled by Seller, the Acquired Companies shall retain for their own benefit all interpretations, data and other records that such Person is entitled to retain under such Seismic License after its termination or cancellation. Similarly, with respect to any Seismic License that is not terminated or cancelled hereunder, the Acquired Companies shall retain for its own benefit all interpretations, data and other records that the Acquired Companies are entitled to retain under such Seismic License.

Section 8.23 Release. Effective as of the Closing, (a) Seller, on its own behalf and on behalf of its Affiliates and their respective heirs, estate, executors, administrators, successors and assigns, hereby unconditionally and irrevocably releases and waives any claims that Seller or any of its Affiliates has or may in the future have, in its capacity as an equity holder, member, manager, director, officer, employee or similar capacity, against either Acquired Company or any of their respective directors, officers, employees, Affiliates or equity holders (or any of their respective Affiliates), in each case arising out of, resulting from or relating to actions, omissions, facts or circumstances occurring, arising or existing at or prior to the Closing, in each case, other than with respect to claims under this Agreement, the Transaction Agreements or any Surviving Agreement and (b) Buyer and each of the Acquired Companies, on their own behalf and on behalf of their respective Affiliates or their respective heirs, estate, executors, administrators, successors and assigns, hereby unconditionally release and waive any claims that Buyer, either of the Acquired Companies or any of their respective Affiliates has or may in the future have

against Seller or any of their respective directors, officers, employees, Affiliates or equity holders (or any of their respective Affiliates) in Seller’s capacity as an equity holder, member, manager or similar capacity of the Company, in each case arising out of, resulting from or relating to actions, commissions, facts or circumstances occurring, arising or existing at or prior to the Closing, in each case, other than with respect to claims under this Agreement, the Transaction Agreements or any Surviving Agreement.

Section 8.24 Right of First Offer. Subject to the last sentence of this Section 8.24, if (i) with respect to any Subject Interests other than Green Canyon Blocks 236, 237, 238, 281 and 282 (collectively, the “Phoenix Field”), at any time within twenty-four (24) months following the date hereof or (ii) with respect to the Phoenix Field, at any time that the Helix Producer I Lease Agreement remains in full force and effect, Buyer, the Company or any of their respective Affiliates desires to offer to any Person an opportunity to participate in the drilling of any Subject Interests owned by either Acquired Company as the Closing Date (in any such case, an “Offer”), Buyer shall first provide to Seller an opportunity to participate in the Offer on the same terms and conditions as the Offer; provided, that Seller’s participation right in each Offer shall be for a working interest of not less than ten percent (10%). Buyer shall provide Seller written notice of each Offer, which such written notice shall include: (i) a complete description of the financial and other terms and conditions of the Offer, and (ii) the amount of the working interest (and associated net revenue interest) being offered to Seller. Seller shall have fifteen (15) days following its receipt of the Offer notice (the “Offer Period”) to accept the Offer. During the Offer Period, Buyer shall, as promptly as practicable, provide Seller with all information and data that Seller reasonably requests to evaluate the Offer (including reasonable access during normal business hours to the employees and representatives of Buyer and the Acquired Companies). If Seller declines the Offer or fails to accept the Offer prior to the expiration of the Offer Period, Buyer and the Company shall have sixty (60) days after the expiration of the Offer Period during which to reach a binding agreement to consummate the transaction contemplated by the Offer, upon the same or more beneficial to Buyer (or any of its Affiliates) terms and conditions described in the Offer. If (i) the transaction contemplated by the Offer is not consummated within such sixty (60) day period, or (ii) the terms and conditions of the Offer are more beneficial to the Person(s) to whom the Offer is made than those provided to Seller in the Offer notice, the transaction contemplated by the Offer may not be consummated and the provisions of this Section 8.24 must be replicated for any future Offer. The provisions of this Section 8.24 shall cease to have any further effect immediately upon (i) with respect to any Asset other than the Phoenix Field, the expiration of twenty-four (24) months following the date hereof or (ii) with respect to the Phoenix Field, the termination of the Helix Producer I Lease Agreement. For the avoidance of doubt, it shall not be considered an Offer if (i) Buyer, the Company or any of their respective Affiliates (A) sells any Asset, (B) sells any or all of the equity of either or both Acquired Companies or (C) conducts an initial public offering or (ii) a Person (other than Buyer, the Acquired Companies or their Affiliates) proposes to Buyer, the Company or any of their respective Affiliates an opportunity to participate in the drilling of any Subject Interests owned by either Acquired Company and such Person is not responding to a solicitation of any kind by Buyer, the Company or any of their respective Affiliates with respect to such drilling opportunity.

Section 8.25 Distribution of Excluded Assets. Prior to the Closing, the Acquired Companies shall be permitted, and the Seller shall cause the Acquired Companies, to convey the

Excluded Assets (whether by assignment, spin-off, dividend or otherwise) in such manner as Seller shall determine; provided that any such conveyance shall be effectuated in as Tax efficient a manner as practicable with respect to each of Seller, the Acquired Companies and Buyer.

Section 8.26 Continuation of Existing Indemnification Obligations. From and after the Closing, Buyer shall and shall cause each of the Acquired Companies to indemnify and hold harmless each respective present and former director and officer of the Acquired Companies against any losses incurred in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, arising out of matters existing or occurring at or prior to the Closing, whether asserted or claimed prior to, at or after the Closing to the fullest extent that the Company was permitted and/or required to indemnify such Person under applicable Law and its respective organizational documents in effect on the date hereof. The provisions of this Section 8.26 are intended to be for the benefit of, and shall be enforceable by, each of the present and former directors and officers of the Acquired Companies, their respective heirs and their respective representatives and shall survive the Closing.

Section 8.27 Green Canyon 237 T-3 Well. Seller shall cause the Acquired Companies to complete the temporary abandonment of the Green Canyon 237 T-3 well prior to November 30, 2012, in accordance with applicable Law, and the cost and expense of such operations shall have been paid in cash prior to the Effective Time or reflected as a payable in the Effective Time Net Working Capital.

Section 8.28 Financing.

(a) Buyer shall use commercially reasonable efforts (taking into account the expected timing of the Marketing Period) to take all actions and to do or cause to be done all things necessary, proper or advisable to obtain the proceeds of the Financing on the terms and conditions described in the Financing Letters (provided, that Buyer may (i) amend the Debt Commitment Letter to add lenders, lead arrangers, bookrunners, syndication agents or similar entities who had not executed the Debt Commitment Letter as of the date of this Agreement or (ii) otherwise replace or amend the Debt Commitment Letter so long as such action would not reasonably be expected to delay or prevent the Closing and the terms are not materially less beneficial to Buyer, with respect to conditionality, than those in the Debt Commitment Letter as in effect on the date of this Agreement). Buyer shall not permit any amendment or modification to be made to, or any waiver of any provision under, the Financing Letters without the prior written consent of Seller if such amendment, supplement, modification or waiver:

(i) with respect to the Financing Letters, reduces the aggregate amount of the Financing (including by increasing the amount of fees to be paid or original issue discount as compared to such fees and original issue discount contemplated by the Debt Commitment Letter and related fee letters in effect on the date hereof unless the Debt Financing or the Equity Financing is increased by such amount);

(ii) (A) imposes new or additional conditions or (B) otherwise adversely expands, amends or modifies any of the conditions precedent to the Financing, or otherwise expands, amends or modifies any other provision of the Financing Letters, in

the case of clause (B), in a manner that would reasonably be expected to prevent or materially delay the ability of Buyer to consummate the Closing on the Closing Date; or

(iii) would otherwise materially adversely impact the ability of Buyer to enforce its rights against other parties to the Financing Letters or otherwise to timely consummate the transactions contemplated by this Agreement.

Buyer shall promptly deliver to Seller copies of any such amendment, modification, waiver or replacement. For purposes of this Agreement, references to “Financing” or “Debt Financing,” as applicable, shall include the financing contemplated by the Financing Letters as permitted to be amended, modified or replaced by this Section 8.28(a) or 8.28(c), and references to “Debt Commitment Letter” shall include such documents as permitted to be amended, modified or replaced by this Section 8.28(a) or 8.28(c).

(b) Buyer shall use commercially reasonable efforts to:

(i) maintain in effect the Financing Letters;

(ii) negotiate and enter into definitive agreements and provide Seller with copies of all substantially final drafts of documents with respect to the Debt Financing on the terms and conditions contained in the Debt Commitment Letter (including the “flex” provisions contained in any related fee letter) or on other terms in the aggregate materially no less favorable to Buyer, as to conditionality, than the terms and conditions in the Debt Commitment Letter; provided, that in no event shall any such definitive agreement contain terms (other than those included in the Debt Commitment Letter) that would reasonably be expected to prevent or materially delay the Closing;

(iii) satisfy (or, if deemed advisable by Buyer, seek the waiver of) on a timely basis all conditions applicable to Buyer that are within its control as set forth in the Financing Letters and to comply with all of its material obligations pursuant to the Debt Commitment Letter;

(iv) upon satisfaction of such conditions, cause the funding of the Debt Financing at or prior to Closing (together with other sources of funds, including the Equity Financing, with respect to amounts required to pay the Required Amounts); and

(v) give Seller prompt notice of any material breach by any party to the Debt Commitment Letters of which Buyer has become aware or any termination of any of the Commitment Letters. Buyer shall give the Company prompt notice of any material adverse change with respect to the Financing. Without limiting the foregoing, Buyer agrees to notify Seller promptly if at any time any financing source that is a party to the Debt Commitment Letter notifies Buyer that such source no longer intends to provide financing on the terms set forth therein.

Notwithstanding anything to the contrary in this Agreement, nothing contained in this Section 8.28(b) shall require, and in no event shall the commercially reasonable efforts of Buyer be deemed or construed to require, Buyer or any Affiliate thereof to (i) seek the Equity Financing from any source other than those counterparty to, or in any amount in excess of that

contemplated by, the Equity Funding Letter or (ii) pay any material fees in excess of those contemplated by the Financing Letters (including pursuant to the “flex” provisions contained in any fee letter relating to the Debt Financing).

(c) If any portion of the Debt Financing becomes unavailable on the terms and conditions contemplated in the Debt Commitment Letter or the Debt Commitment Letter is terminated or modified in a manner materially adverse to Buyer for any reason, Buyer shall promptly notify Seller in writing and shall use its commercially reasonable efforts to arrange to obtain alternative financing from alternative sources for such portion as promptly as practicable following such event on terms no less favorable to Buyer in any material respect as those contained in the Debt Commitment Letter and in an amount sufficient, together with the Equity Financing and cash on hand of the Acquired Companies, if any, to fund the Required Amount (the “Alternate Financing”) and, if obtained, will provide Seller with a copy of, a new financing commitment that provides for at least the same amount of financing as provided under the Debt Commitment Letter originally issued, to the extent needed to fund the Required Amount, and on terms and conditions (including all terms, termination rights, flex provisions and funding conditions) no less favorable in any material respect to Buyer than those included in the Debt Commitment Letter (an “Alternate Debt Commitment Letter”). Buyer shall use its commercially reasonable efforts (taking into account the expected timing of the Marketing Period) to take, or cause to be taken, all actions and things necessary, proper or advisable to arrange promptly and consummate the Alternate Financing on the terms and conditions described in any Alternate Debt Commitment Letter, including by complying with its obligations under clause (b) above as though the references therein to Debt Commitment Letter and Debt Financing were instead references to the Alternate Financing and the Alternate Debt Commitment Letter.

Notwithstanding anything to the contrary in this Agreement, Buyer may enter discussions regarding, and may enter into arrangements and agreements relating to the Financing to add other equity providers, so long as in respect of any such arrangements and agreements, the following conditions are met: (i) the aggregate amount of the Equity Financing is not reduced; (ii) the arrangements and agreements, in the aggregate, would not be reasonably likely to delay or prevent the Closing and (iii) the arrangements and agreements would not diminish or release the pre-closing obligations of the parties to the Equity Funding Letter, adversely affect the rights of Buyer to enforce its rights against the other parties to the Equity Funding Letter, or otherwise constitute a waiver or reduction of Buyer’s rights under the Equity Funding Letter.

(d) Prior to the Closing Date or as expressly provided for in clause (iv) below, Seller shall use its commercially reasonable efforts to provide, and shall cause the Acquired Companies to use commercially reasonable efforts to provide, and shall use commercially reasonable efforts to cause its respective Representatives to use commercially reasonable efforts to provide, to Buyer such cooperation as may be reasonably requested by Buyer with respect to the Financing; provided, that such requested cooperation does not materially and adversely interfere with the Acquired Company’s business and that any information requested by Buyer is reasonably available to Seller and/or the Acquired Companies. Such cooperation shall include:

(i) using commercially reasonable efforts to, as promptly as reasonably practical, (x) furnish Buyer and Buyer’s financing sources and their respective Representatives with the Required Information; and (y) inform Buyer if the Company

shall have knowledge of any facts that would likely require the restatement of such financial statements for such financial statements to comply with GAAP;

(ii) using commercially reasonable efforts to participate in a reasonable number of presentations and due diligence sessions in connection with the Financing;

(iii) using commercially reasonable efforts to assist with the preparation of materials for rating agency presentations, private placement memoranda, offering documents, bank information memoranda and similar documents required in connection with the Financing, including the execution and delivery of customary representation letters in connection with bank information memoranda and reviewing and commenting on Buyer’s draft of a business description and “Management’s Discussion and Analysis” of Seller’s financial statements to be included in offering documents contemplated by the Debt Financing;

(iv) using commercially reasonable efforts to provide Buyer upon request a copy of each semi-annual proved oil and gas reserves report, which may be prepared internally by petroleum engineers who are employees of the Company, for the period ended June 30, 2012 together with audit reports prepared by third-party independent petroleum engineering firms reasonably acceptable to Buyer and the debt financing sources in respect of any such reports prepared as of December 31, 2011, and including consents from such independent petroleum engineering firms to inclusion of such reports in any offering documents, private placement memoranda, bank information memoranda, prospectuses and similar documents in connection with the Financing;

(v) (A) using commercially reasonable efforts to assist Buyer and its financing sources in obtaining and providing customary accountants’ comfort letters and (B) using commercially reasonable efforts to obtain title information and other documentation and items relating to the Debt Financing, as contemplated by the Debt Commitment Letter or reasonably requested by Buyer and, if requested by Buyer, to cooperate with and assist Buyer in obtaining such documentation and items;

(vi) both before the Closing and, to the extent reasonably necessary to allow Buyer or any of its Affiliates to consummate a securities offering or comply with SEC requirements, after the Closing, providing appropriate representations to its accountants in connection with the preparation of financial statements and other financial data of each Acquired Company and requesting accountants’ consents in connection with the use of each Acquired Company’s financial statements in offering documents, prospectuses, Current Reports on Form 8-K and other documents to be filed with the SEC (or similar documents required to be delivered under the terms of the definitive documentation for the Financing);

(vii) using commercially reasonable efforts to assist Buyer in connection with the preparation of pro forma financial information and financial statements contemplated by the Debt Commitment Letter or to the extent required by SEC rules and regulations or necessary (or reasonably required by Buyer’s financing sources) to be included in any offering documents; provided that Buyer shall have provided Seller or the Acquired

Companies with information relating to the proposed debt and equity capitalization that is required for such pro forma financial information in financial reports;

(viii) using commercially reasonable efforts to provide monthly management reports for each fiscal month ended on or after September 30, 2012 and at least 30 days before the Closing Date;

(ix) using commercially reasonable efforts to execute and deliver as of the Closing any pledge and security documents, other definitive financing documents, or other certificates or documents as may be reasonably requested by Buyer and otherwise facilitating the pledging of collateral (including cooperation in connection with the pay-off of existing Indebtedness and the release of related Liens and termination of security interest);

(x) using commercially reasonable efforts to assist Buyer in obtaining waivers, consents, estoppels and approvals from other parties to material leases, other than rights of way and other encumbrances and contracts to which any Acquired Company is a party and to arrange discussions among Buyer, the Equity Providers and the Debt Providers and their respective Representatives with other parties to material leases, rights of way and other encumbrances and contracts as of the Closing;

(xi) taking all commercially reasonable actions necessary to (A) permit the prospective lenders involved in the Debt Financing (through any Debt Provider) and the Debt Providers to evaluate the Company’s current assets, cash management and accounting systems, policies and procedures relating thereto for the purposes of establishing collateral arrangements as of the Closing and to assist with other collateral audits and due diligence examinations reasonable and customary for oil and gas industry reserve-based financing and (B) establish bank and other accounts and blocked account agreements and lock box arrangements to the extent necessary in connection with the Debt Financing;

(xii) using commercially reasonable efforts to take all corporate actions, subject to the occurrence of the Closing, reasonably requested by Buyer that are necessary or customary to permit the consummation of the Debt Financing, including any high-yield financing, and to permit the proceeds thereof, together with the cash at each Acquired Company, if any (not needed for other purposes), to be made available on the Closing Date to consummate the transactions contemplated by this Agreement; and

(xiii) using commercially reasonable efforts to provide all documentation and other information about the Acquired Companies as is required by applicable “know your customer” and anti-money laundering rules and regulations including without limitation the USA PATRIOT Act to the extent reasonably requested at least five (5) Business Days prior to the anticipated Closing Date;

provided, that no obligation of any Acquired Company, or any Lien on any of their respective assets, in connection with the Financing shall be effective until the Closing; no Acquired Company or any Representatives of any of the foregoing shall be required to pay any

commitment or other fee or incur any other liability in connection with the Financing prior to the Closing; and no director or officer of any Acquired Company shall be required to execute any agreement, certificate, document or instrument with respect to the Financing that would be effective prior to the Closing.

(e) Seller shall, and shall cause the Company to, use commercially reasonable efforts to periodically update any Required Information provided to Buyer as may be necessary so that such Required Information is (i) Compliant, (ii) meets the applicable requirements set forth in the definition of “Required Information” and (iii) would not, after giving effect to such update(s), result in the Marketing Period to cease to be deemed to have commenced. For the avoidance of doubt, Buyer may, to most effectively access the financing markets, require the cooperation of the Company under Section 8.28(d) at any time, and from time to time and on multiple occasions, between the date hereof and the Closing; provided that, for the avoidance of doubt, the Marketing Period shall not be applicable as to each attempt to access the markets. Seller shall timely (taking into account any extensions permitted by the applicable SEC rules) file SEC documents and other materials with the SEC to the extent required by the SEC in accordance with applicable Law to the extent such SEC documents relate specifically to any Acquired Company. If, in connection with a marketing effort contemplated by the Debt Commitment Letter, Buyer reasonably requests Seller to file a Current Report on Form 8-K pursuant to the Securities Exchange Act of 1934, as amended, that contains material non-public information with respect to any Acquired Company, which Buyer reasonably determines (in consultation with Seller) to include in a customary information or offering memorandum for the Debt Financing, then, upon Seller’s review of and reasonable satisfaction with such filing, Seller shall file such Current Report on Form 8-K.

(f) Seller hereby consents to the use of its logos in connection with the Financing; provided, that such logos are used solely in a manner that is not intended to or reasonably likely to harm or disparage Seller or the reputation or goodwill of Seller.

(g) Buyer shall promptly, upon request by Seller, reimburse Seller or the Company, as applicable, for all reasonable and documented out-of-pocket costs and expenses (including reasonable attorneys’ fees) incurred by such Person in connection with its cooperation contemplated by this Section 8.28.

(h) Buyer shall indemnify and hold harmless Seller and the Acquired Companies and their respective Representatives from and against any and all liabilities, losses, damages, claims, costs or expenses suffered or incurred by any of them in connection with the Financing (other than information provided in writing specifically for use by or on behalf of any Seller or either Acquired Company), in each case other than to the extent any of the foregoing arises from the bad faith, gross negligence or willful misconduct of, or material breach of this Agreement by, any of the Acquired Companies or any of their respective Affiliates and Representatives.

(i) The Parties agree that the overriding royalty interests assigned from the Company to Seller pursuant to the Assignments and the Wang ORRI Assignment shall be recorded prior to any Liens that may be recorded in connection with the Financing.

Section 13.2 Indemnification By Seller.

Section 13.3 Indemnification and Defense Procedures. Claims for indemnification under this Agreement shall be asserted and resolved as follows:

(a) If any Person who or which is entitled to seek indemnification under this Agreement (an “Indemnified Party”) receives notice of the assertion or commencement of any claim asserted against an Indemnified Party by a third Person (“Third Party Claim”) in respect of any matter that is subject to indemnification under this Agreement, the Indemnified Party shall promptly (i) notify the Party obligated to indemnify the Indemnified Party pursuant to this Agreement, (the “Indemnifying Party”) of the Third Party Claim and (ii) transmit to the Indemnifying Party a written notice (“Claim Notice”) describing in reasonable detail the nature of the Third Party Claim, a copy of all papers served with respect to such claim (if any), the Indemnified Party’s best estimate of the amount of Covered Liabilities attributable to the Third Party Claim and the basis of the Indemnified Party’s request for indemnification under this Agreement. Failure to timely provide such Claim Notice shall not affect the right of the Indemnified Party’s indemnification hereunder, except to the extent the Indemnifying Party is materially prejudiced by such delay or omission.

(b) If the Indemnifying Party admits (in writing) its obligation to indemnify the Indemnified Party with respect to any Third Party Claim, then the Indemnifying Party shall have the right to defend, at its sole cost and expense, the Indemnified Party against such Third Party Claim with counsel selected by the Indemnifying Party (who shall be reasonably satisfactory to the Indemnified Party), by all appropriate proceedings, to a final conclusion or settlement at the discretion of the Indemnifying Party in accordance with this Section 13.3(b). The Indemnifying Party shall have full control of such defense and proceedings, including any compromise or settlement thereof; provided that the Indemnifying Party shall not enter into any settlement agreement without the written consent of the Indemnified Party; provided further, that such consent shall not be required if (i) the settlement agreement contains a complete and unconditional general release by the third Person asserting the claim to all Indemnified Parties affected by the claim, (ii) the settlement agreement does not contain any sanction or restriction upon the conduct of any business by the Indemnified Party or its Affiliates and (iii) the settlement agreement does not create a financial or other obligation on the part of the Indemnified Party or any other Person other than the Indemnifying Party. If requested by the Indemnifying Party, the Indemnified Party agrees, at the sole cost and expense of the Indemnifying Party, to cooperate with the Indemnifying Party and its counsel in contesting any Third Party Claim that the Indemnifying Party elects to contest, including the making of any reasonably related counterclaim against the Person asserting the Third Party Claim or any cross complaint against any Person and making the books and records and personnel of the Indemnified Party reasonably available during normal business hours. The Indemnified Party may participate in, but not control, any defense or settlement of any Third Party Claim controlled by the Indemnifying Party pursuant to this Section 13.3(b), and the Indemnified Party shall bear its own costs and expenses with respect to such participation.

(c) If the Indemnifying Party does not admit (in writing) its obligation to indemnify the Indemnified Party pursuant to Section 13.3(b), then the Indemnified Party shall have the right to defend, and be reimbursed for its reasonable cost and expense (but only if the Indemnified Party is actually entitled to indemnification hereunder) in regard to the Third Party Claim with counsel selected by the Indemnified Party (who shall be reasonably satisfactory to the Indemnifying Party), by all appropriate proceedings, which proceedings shall be prosecuted diligently by the Indemnified Party. In such circumstances, the Indemnified Party shall defend any such Third Party Claim in good faith and have full control of such defense and proceedings;

provided, however, that the Indemnified Party may not enter into any compromise or settlement of such Third Party Claim if indemnification is to be sought hereunder, without the Indemnifying Party’s consent (which consent shall not be unreasonably withheld, conditioned or delayed). The Indemnifying Party may participate in, but not control, any defense or settlement controlled by the Indemnified Party pursuant to this Section 13.3(c), and the Indemnifying Party shall bear its own costs and expenses with respect to such participation.

(d) Any claim by an Indemnified Party for indemnification under this Agreement that does not result from a Third Party Claim (a “Direct Claim”) will be asserted by giving the Indemnifying Party reasonably prompt written notice thereof, but in any event not later than thirty (30) days after the Indemnified Party becomes aware of such Direct Claim. Failure to timely provide such notice of a Direct Claim shall not affect the right of the Indemnified Party’s indemnification hereunder, except to the extent the Indemnifying Party is materially prejudiced by such delay or omission. Such notice by the Indemnified Party will describe the Direct Claim in reasonable detail, will include copies of all available material written evidence thereof and will indicate the estimated amount, if reasonably practicable, of damages that has been or may be sustained by the Indemnified Party. The Indemnifying Party will have a period of fifteen (15) Business Days within which to respond in writing to such Direct Claim. If the Indemnifying Party does not so respond within such fifteen (15) Business Day period, the Indemnifying Party will be deemed to have rejected such claim, in which event the Indemnified Party will be free to pursue such remedies as may be available to the Indemnified Party on the terms and subject to the provisions of this Agreement.

(e) Notwithstanding anything to the contrary contained in this Agreement, Seller shall indemnify, defend, hold harmless and reimburse the Buyer Indemnified Persons from and against any and all Covered Liabilities suffered or incurred by a Buyer Indemnified Person as a result of or arising out of the Schedule 13.2(c) Litigation at its sole cost and expense. Seller shall have full control of the defense and proceedings in or relating to the Schedule 13.2(c) Litigation, including any compromise or settlement thereof (subject to the final sentence of this clause (e)) and, in the event Buyer, any Acquired Company or any of their respective Affiliates settles all or any part of the Schedule 13.2(c) Litigation over the objection of Seller, Seller’s indemnity obligations set forth in Section 13.2(c) and its obligations under this Section 13.3(e) (including but not limited to any right to such indemnity hereunder or thereunder) with respect to such settled claims shall be deemed to have been waived by Buyer, and Buyer shall not be entitled to any payment by Seller with respect to such settled claims. Buyer agrees that it shall, and it shall cause each Acquired Company and any of their respective Affiliates to, (i) reasonably cooperate, at Seller’s sole cost and expense, in the defense and proceedings in or relating to the Schedule 13.2(c) Litigation (including, without limitation, bringing any counterclaim or cross-complaint against any Person), (ii) promptly provide to Seller all information related to or in connection with the Schedule 13.2(c) Litigation and without costs and expenses to Buyer, the Acquired Companies and any of their respective Affiliates, and (iii) make all employees of the Acquired Companies and their respective Affiliates reasonably available for consultation, deposition, and trial testimony, without the necessity of the subpoena and without costs and expenses to Buyer, the Acquired Companies and their respective Affiliates; provided, that Seller shall not be charged for the costs of any lost time for employees. Neither the Buyer, the Acquired Companies nor any other Person on their behalf shall file any motion, answer or other pleading in connection with the Schedule 13.2(c) Litigation without the prior written consent of Seller. Seller shall not,

without the written consent of Buyer, settle the Schedule 13.2(c) Litigation or consent to the entry of any judgment with respect thereto unless (i) the settlement agreement or judgment contains a complete and unconditional general release by the Person asserting the claim to all Indemnified Parties affected by the claim, (ii) the settlement agreement or judgment does not contain any sanction or restriction upon the conduct of any business by the Indemnified Party or its Affiliates and (iii) the settlement agreement does not create a financial or other obligation on the part of the Indemnified Party other than a financial obligation with respect to which the Indemnified party is fully indemnified hereunder.

Section 13.4 Seller’s General Liability Limitation.

(a) Notwithstanding anything herein provided to the contrary, except with respect to breaches of Seller Fundamental Representations (or the corresponding representations and warranties given in the Seller’s Closing Certificate) and Seller’s representations and warranties in Section 4.2(k) (or the corresponding representations and warranties given in the Seller’s Closing Certificate) for which the limitations set forth in this Section 13.4(a) shall not apply, Seller shall have no liability to Buyer or any of the other Buyer Indemnified Persons pursuant to Section 13.2(a) for any breach of a representation or warranty by Seller until and unless (i) any individual Covered Liability or group or series of related Covered Liabilities covered by Section 13.2(a) attributable to any breach by Seller of this Agreement exceeds $100,000 (such Covered Liability or group or series of related Covered Liabilities that does not exceed $100,000, the “DeMinimis Claims”), provided, however, that any group or series of Covered Liabilities arising out of the same occurrence shall be aggregated and treated as an individual Covered Liability for purposes of determining whether they are a DeMinimis Claim, and (ii) the aggregate amount of all Covered Liabilities attributable to any breach of representations or warranties by Seller in this Agreement exceeds an amount equal to two percent (2%) of the sum of the Deposit plus the Adjusted Purchase Price (as same may be further adjusted downward after the Closing pursuant to Sections 3.1(j), 3.1(k), 7.2(c)(ii) and 7.5) (the “Deductible”) and then only to the extent the amount of such Covered Liabilities exceed the Deductible.

(b) Notwithstanding anything herein provided to the contrary, Seller shall have no liability to Buyer or any of the other Buyer Indemnified Persons for any breach of a representation or warranty by Seller that is not a Seller Fundamental Representation (or the corresponding representations and warranties given in the Seller’s Closing Certificate) or set forth in Section 4.2(k) (or the corresponding representations and warranties given in the Seller’s Closing Certificate) to the extent that the aggregate amount of all Covered Liabilities attributable to any breach of such representations or warranties by Seller in this Agreement exceeds an amount equal to fifteen (15%) percent of the sum of the Deposit plus the Adjusted Purchase Price (as same may be further adjusted downward after the Closing pursuant to Sections 3.1(j), 3.1(k), 7.2(c)(ii) or 7.5). In addition, Seller shall have no liability to Buyer or any other Buyer Indemnified Person for any breach of a representation or warranty by Seller that is a Seller Fundamental Representation (or the corresponding representations and warranties given in the Seller’s Closing Certificate) or set forth in Section 4.2(k) (or the corresponding representations and warranties given in the Seller’s Closing Certificate) to the extent that the aggregate amount of all Covered Liabilities attributable to any breach of the representations or warranties by Seller in this Agreement exceed the sum of the Deposit plus the Adjusted Purchase Price (as the same

(c) Each Buyer Indemnified Person shall be required to use commercially reasonable efforts to mitigate Covered Liabilities with respect to which a claim for indemnification is made and shall reasonably consult with Seller with a view toward mitigating such Covered Liabilities in conjunction with all claims for which a Buyer Indemnified Person seeks indemnification under this Article 13. Notwithstanding anything to the contrary herein, the amount of any Covered Liabilities incurred or suffered by any Buyer Indemnified Person shall be calculated after giving effect to (i) any insurance proceeds (net of costs incurred in prosecuting the insurance claim) actually received by the Buyer Indemnified Person (or any of its Affiliates) with respect to such Covered Liabilities, and (ii) any recoveries actually obtained by the Buyer Indemnified Person (or any of its Affiliates) from any other third Person.

Section 13.6 Exclusive Remedy. Except as specifically set forth in Article 7, the remedies provided in this Article 13 shall be the sole and exclusive legal remedies of the Parties, from and after the Closing, with respect to this Agreement and the transactions contemplated hereby; provided that nothing in this Section 13.6 shall prevent either Party from (i) seeking specific performance, injunctive and/or equitable relief for claims of breach or failure to perform covenants performable under this Agreement or (ii) pursuing, and recovering in respect of, any claim based on actual fraud involving a knowing and intentional misrepresentation or omission of a material fact or willful or intentional breach.

Section 13.7 Effect of Investigation. Representations and warranties set forth in this Agreement or any certificate delivered at Closing, including Seller’s Closing Certificate, and covenants of Buyer and Seller, and the Seller Indemnified Person’s or Buyer Indemnified Person’s right to indemnification with respect thereto shall not be affected or deemed waived by reason of any investigation made by or on behalf of any Seller Indemnified Person or Buyer Indemnified Person, as the case may be, or by any of their respective Representatives, whether before or after the execution and delivery of this Agreement, or by reason of the fact that any Seller Indemnified Person or Buyer Indemnified Person, or any of their respective Representatives knew (including knowledge obtained by the Schedule Updates) or should have known that any such representation or warranty is, was or might be inaccurate or noncompliance with a covenant or by reason of Seller’s or Buyer’s waiver of any condition set forth in Sections 9.1 or 9.2, as the case may be.

Section 13.8 Tax Treatment of Indemnification Payments. Any indemnification payments made pursuant to this Agreement between the Parties shall be treated as an adjustment to the Purchase Price for Tax purposes.

deemed to have been made without any such qualification for purposes of determining (i) whether a breach of any such representation or warranty has occurred and (ii) the amount of Covered Liabilities resulting from arising out of or relating to any such breach of representation or warranty.

ARTICLE 14

TERMINATION; REMEDIES

Section 14.1 Termination.

(a) Termination of Agreement. This Agreement and the transactions contemplated hereby may be terminated at any time prior to the Closing:

(i) By the mutual written consent of Seller and Buyer; or

(ii) By either Party, if the Closing has not occurred by the close of business on or before March 29, 2013 (as may be extended in accordance with this Section 14.1(a)(ii), the “Drop-Dead Date”); provided, that, the right to terminate this Agreement under this Section 14.1(a)(ii) shall not be available to any Party whose breach of this Agreement shall have been the cause of, or shall have resulted in, the failure of the Closing to occur on or before the Drop-Dead Date; provided, further, that if the Marketing Period has commenced prior to such date and has not been completed by such date, such date shall be extended until the third (3rd) Business Day after the date on which the Marketing Period is completed.

(b) Effect of Termination. Without limiting Seller’s and Buyer’s respective remedies and rights in regard to the Deposit under Section 14.2, in the event of termination of this Agreement by Seller, on the one hand, or Buyer, on the other hand, pursuant to Section 14.1(a), written notice thereof shall forthwith be given by the terminating Party or Parties to the other Party or Parties, and this Agreement shall thereupon terminate; provided, however, that following any termination of this Agreement, Buyer will continue to be bound by its obligations set forth in Sections 5.1, 5.2 and 6.1; and provided, further, that (i) this Section 14.1(b), Section 12.3 and Article 1 and Article 15 will survive the termination of this Agreement and will remain in full force and effect and (ii) subject to Section 14.2, the termination of this Agreement will not relieve any Party from any liability for any breach of this Agreement occurring prior to termination. If this Agreement is terminated as provided herein all filings, applications and other submissions made to any Governmental Authority shall, to the extent practicable, be withdrawn from the Governmental Authority to which they were made.

Section 14.2 Remedies.

(a) Seller’s Remedies. Notwithstanding anything herein provided to the contrary, upon Buyer’s breach of any representation, warranty or covenant contained in this Agreement such that Seller would be entitled to terminate this Agreement pursuant to Section 14.1(a)(ii), Seller, at its sole option, may, as Seller’s sole and exclusive remedy (including against the Debt Providers and their respective current, former or future directors, officers, general or limited partners, stockholders, members, managers, controlling persons, Affiliates, employees or Representatives) (i) enforce specific performance to close the transactions contemplated by this

Agreement (subject to Section 15.2) or (ii) terminate this Agreement and retain the Deposit as liquidated damages, as Seller’s sole and exclusive remedies for such breach, all other remedies being expressly waived by Seller (including against the Debt Providers and their respective current, former or future directors, officers, general or limited partners, stockholders, members, managers, controlling persons, Affiliates, employees or Representatives). Seller and Buyer agree upon the Deposit amount as liquidated damages due to the difficulty and inconvenience of measuring actual damages and the uncertainty thereof, and Seller and Buyer agree that the Deposit amount is a reasonable estimate of Seller’s loss in the event of any such default by Buyer.

(b) Buyer’s Remedies. Notwithstanding anything herein to the contrary, upon Seller’s breach of any representation, warranty or covenant contained in this Agreement such that Buyer would be entitled to terminate this Agreement pursuant to Section 14.1(a)(ii), Buyer, at its sole option, may (i) enforce specific performance of this Agreement or (ii) terminate this Agreement, receive back the entirety of the Deposit and be reimbursed by Seller by wire transfer within three (3) Business Days following such termination an amount equal to Buyer’s documented reasonable out-of-pocket fees and expenses set forth in Buyer’s termination notice incurred by Buyer in connection with this Agreement and the transactions contemplated hereby, including attorney’s fees, accountant’s fees and the expense of environmental and title examination, as Buyer’s sole and exclusive remedy for such default, all other remedies being expressly waived by Buyer; provided, however, in no event shall Buyer’s reimbursable fees and expenses under this Section 14.2(b) exceed $5,000,000. In the event that this Agreement is terminated under Section 14.1(a) and Seller is not entitled to retain the Deposit under Section 14.2(a), Buyer shall be entitled to receive back the entirety of the Deposit.

(c) Escrow. Promptly, but in no event later than three (3) Business Days after the termination date of this Agreement, the Parties shall execute and deliver to the Escrow Agent written instructions instructing the Escrow Agent to disburse via wire transfer of immediately available funds the entirety of the Deposit to the Party entitled to receive the Deposit as provided in this Section 14.2.

The inclusion of any matter, information or item in any Appendix, Schedule (including amendments and supplements thereto) or Exhibit hereto shall not be deemed to constitute an admission of any liability by Seller or the Company to any third Person or otherwise imply that any such matter, information or item is material or creates a measure for materiality for the purposes of this Agreement. No disclosure in the Appendices, Schedules (including amendments and supplements thereto) and Exhibits hereto relating to any

possible breach or violation of any agreement or Law shall be construed as an admission or indication that any such breach or violation exists or has actually occurred.

Section 15.9 Interpretation. It is expressly agreed that this Agreement shall not be construed against any Party, and no consideration shall be given or presumption made, on the basis of who drafted this Agreement or any particular provision hereof or who supplied the form of Agreement.

(a) examples shall not be construed to limit, expressly or by implication, the matter they illustrate;

(b) the word “includes” and its derivatives means “includes, but is not limited to” and corresponding derivative expressions;

(c) a defined term has its defined meaning throughout this Agreement and each Appendix, Exhibit and Schedule (including amendments and supplements thereto) to this Agreement, regardless of whether it appears before or after the place where it is defined;

(d) each Appendix, Exhibit and Schedule (including amendments and supplements thereto) to this Agreement is a part of this Agreement, but if there is any conflict or inconsistency between the main body of this Agreement (including Appendix A which shall be considered part of the main body of this Agreement) and any Appendix, Exhibit or Schedule (including amendments and supplements thereto), the provisions of the main body of this Agreement shall prevail;

(e) the term “cost” includes expense and the term “expense” includes cost; and

(f) the headings and titles herein are for convenience only and shall have no significance in the interpretation hereof.

Section 15.10 Limited Arbitration. Except to the limited extent expressly provided in Section 7.5, disputes and differences arising under or out of, in relation to or in any way connected with this Agreement shall not be subject to arbitration.

Section 15.11 Agreement for the Parties’ Benefit Only. Except as provided in Section 8.12 and Article 13, this Agreement is for the sole benefit of Buyer, Seller and their respective successors and assigns as permitted herein and no other Person shall be entitled to enforce this Agreement, rely on any representation, warranty, covenant or agreement contained herein, receive any rights hereunder or be a third party beneficiary of this Agreement, provided that the Debt Providers and their respective current, former or future Representatives, general or limited partners, stockholders, members, managers, controlling persons or Affiliates, shall be third party beneficiaries of Sections 14.2, 15.2(a), 15.2(b), 15.2(c), 15.2(e) and this Section 15.11.

Section 15.12 Attorneys’ Fees. The prevailing Party in any legal proceeding brought under or to enforce this Agreement shall be additionally entitled to recover court costs and reasonable attorneys’ fees from the nonprevailing Party.

Section 15.13 Severability. If any term, provision or condition of this Agreement, or any application thereof, is held invalid, illegal or unenforceable in any respect under any Law, this Agreement shall be reformed to the extent necessary to conform, in each case consistent with the intention of the Parties, to such Law, and to the extent such term, provision or condition cannot be so reformed, then such term, provision or condition (or such invalid, illegal or unenforceable application thereof) shall be deemed deleted from (or prohibited under) this Agreement, as the case may be, and the validity, legality and enforceability of the remaining terms, provisions and conditions contained herein (and any other application of such term, provision or condition) shall not in any way be affected or impaired thereby. Upon such determination that any term or other provision or condition is invalid, illegal or incapable of being enforced, the Parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible in an acceptable manner to the end that the transactions contemplated hereby are fulfilled to the extent possible.

Section 15.14 No Recordation. Without limiting any Party’s right to file suit to enforce this Agreement or to compel arbitration pursuant to Section 7.5 of this Agreement, the Parties expressly covenant and agree not to record or place of record this Agreement or any copy or memorandum hereof.

Section 15.15 Time of Essence. Time is of the essence in this Agreement. If the date specified in this Agreement for giving any notice or taking any action is not a Business Day (or if the period during which any notice is required to be given or any action taken expires on a date that is not a Business Day), then the date for giving such notice or taking such action (and the expiration date of such period during which notice is required to be given or action taken) shall be the next day that is a Business Day.
