At Closing, and to the extent assignable, Seller will, or will cause its Affiliates to, assign to Buyer the benefits under any and all confidentiality agreements between Seller, or any of its Affiliates, and any third party in connection with the potential sale or other disposition by Seller and its Affiliates of the Companies or the Properties.

Section 7.8. Officer and Director Resignation and Releases. At the Closing, Seller shall deliver to Buyer (a) resignations of the respective managers of such Company in the form and substance attached hereto as Exhibit 7.8(a), such resignations to be effective immediately upon the consummation of the transactions contemplated by this Agreement and (b) subject to the provisions of Section 7.10, releases from all officers, managers and key employees and sponsor, if any, releasing such Company, Seller and their Affiliates from any and all claims of such individuals against them, substantially in the form and substance attached hereto as Exhibit 7.8(b).

Section 7.9. Indemnification of Managers and Officers. For a period of 180 days after the Closing Date, neither Buyer nor any Company or such Company’s members shall amend, repeal or otherwise modify the Governing Documents of a Company or manage a Company in any manner that would affect adversely the rights thereunder of persons who at and any time prior to the Closing Date were managers or officers of such Company or which would affect any elimination from liability of any such persons. Buyer acknowledges and agrees that the indemnification provisions in favor of the manager in the Governing Documents of the Companies may be amended to include officers of the Companies within the scope of such indemnification. In the event any claim or claims are asserted or made pursuant to the indemnification rights set forth in this Section 7.9 prior to the date that is 180 days after the Closing Date, all rights to indemnification in respect of any such claim or claims shall continue until the disposition of any and all such claims. Any determination required to be made with respect to whether a person’s conduct complies with the applicable standard of conduct shall be made by independent legal counsel selected by any such manager or officer reasonably acceptable to Buyer. Except with respect to claims for indemnification made by an officer or manager within 180 days following the Closing, all indemnification obligations of the Companies to and all indemnification agreements with managers and officers shall terminate on the 180^th day following Closing. The releases referenced in Section 7.8 will release the Companies from all indemnification obligations except as provided in this Section 7.9.

Section 7.10. Employee Matters.

(a) From and after the Execution Date through ten (10) Business Days before the Closing Date, Buyer or an Affiliate of Buyer may offer employment, conditioned on the Closing, to any or all Employees referenced on Section 7.10(a) of the Disclosure

Schedule (the “Designated Employees”) to be effective as of 12:01 a.m. on the Closing Date (or with respect to a Designated Employee who is on a leave of absence, effective as of 12:01 am on such later date as such Designated Employee is released to return to work or is entitled to be restored to employment) (the “Hire Date”). Each offer of employment shall be on such terms and conditions of employment that would apply to similarly situated employees of Buyer; provided, however, that each such offer shall provide an initial annual salary or hourly wage rate that is not less than the annual salary or hourly wage rate for such Designated Employee immediately before the Closing Date and employee benefits that are substantially similar in the aggregate to the employee benefits offered to similarly situated employees of Buyer. No later than five (5) Business Days before the Closing Date, Buyer shall notify Seller of the identities of the Designated Employees, if any, to whom Buyer or an Affiliate of Buyer made such an offer of employment and who accepted such offer and the Designated Employees, if any, to whom Buyer or an Affiliate did not make such an offer of employment. The Designated Employees, if any, who have accepted such an offer of employment and begin employment with Buyer or an Affiliate are referred to as the “Hired Employees”. Except as specifically provided for in this Section, nothing in this Agreement obligates Buyer to continue the employment of any Hired Employee for any period of time or otherwise affects Buyer’s right to set or modify the terms and conditions of employment of such Hired Employees.

(b) From and after the Closing, the Hired Employees will be covered under such employee compensation and benefit plans, policies, programs or arrangements as Buyer or an Affiliate may make available to them in accordance with subsection (a) of this Section, provided that such plans shall include medical, dental and vision coverage, health care flexible spending account and a tax-qualified defined contribution plan with a 401(k) feature. Buyer shall, to the extent permitted under Applicable Law, provide, or cause its Affiliates to provide, all Hired Employees with prior service credit for all periods of service with Seller and its Affiliates for all purposes of Buyer’s and its Affiliates’ employee benefit plans, programs and arrangements, including without limitation for purposes of eligibility, participation, vesting and levels of benefit accruals; provided, however, that with respect to calendar year 2012, Seller shall pay for vacation, sick and other paid leave accrued by the Hired Employees with SBO and its Affiliates as of the Closing Date. Buyer shall, to the extent allowed under Applicable Law, cause, or cause its Affiliates to cause, any pre-existing condition limitations or eligibility waiting periods or required physical examinations under any Buyer or its affiliate’s plan providing healthcare benefits to be waived with respect to the Hired Employees and their eligible dependents.

(c) Seller currently maintains one or more defined contribution plans (the “Seller DC Plan”) which provide certain retirement benefits for the Hired Employees. Effective as of the Closing Date, with respect to the Hired Employees, Seller shall take all necessary and appropriate action to amend the Seller DC Plan in which such employees participate to provide that such employees receive full and immediate vesting in any employer-derived benefits accrued under such plan. As soon as reasonably practicable after the Closing Date, with respect to each Hired Employee who is a participant in the Seller DC Plan, Seller shall (i) provide each such employee with the

right to receive a distribution of such Hired Employee’s vested interest under such plan and an election to roll over such vested interest in the Seller DC Plan to a tax-qualified defined contribution plan maintained by Buyer or an Affiliate of Buyer (the “Buyer DC Plan”), and (ii) cause the trustee of the plan to roll over the vested interest which the Hired Employee elects to roll over to the Buyer DC Plan. Buyer shall cause the Buyer DC Plan to accept any such rollovers.

(d) Buyer shall be solely responsible, and shall indemnify Seller and its directors, officers and Affiliates for any costs, losses or liabilities incurred by Seller or any of its Affiliate(s) to the extent arising out of Buyer’s determination of which Designated Employees to make offers to or the actions or omissions of Buyer or its Affiliates from and after the Closing Date with respect to the Hired Employees.

Section 7.11. Taxes .

(a) Buyer and Seller agree to treat the purchase and sale of the Interests for federal income Tax purposes as a purchase and sale of all of the assets of the Companies, other than the Excluded Properties.

(b) Seller shall (i) pay and indemnify Buyer and its Affiliates (including the Companies) with respect to, all Taxes of the Companies due, which are attributable to, or which relate to the Properties and operations of the Companies during the Pre-Effective Date Tax Period, including the Pre-Effective Date Straddle Period, except for Taxes taken into account as a reduction to the Base Purchase Price under Section 12.1 or as a liability in determining Final Net Working Capital under Article XII, and (ii) indemnify Buyer and its Affiliates (including the Companies) from and against any breach of the representations contained in Section 4.11 of this Agreement, except for Taxes taken into account as a reduction to the Base Purchase Price under Section 12.1 or as a liability in determining Final Net Working Capital under Article XII.

(c) Seller shall have no liability for, and Buyer shall be solely liable for and shall pay, all Taxes of the Companies due for any taxable year or taxable period beginning after the Effective Date, and all Taxes attributable to a Post-Effective Date Straddle Period (as defined below).

(d) Subject to Article XII, in the case of Taxes that are payable with respect to any Straddle Period of the Company, for purposes of allocating such Taxes between that portion of the Straddle Period ending on or before the Effective Date (the “Pre-Effective Date Straddle Period”) and that portion of the Straddle Period beginning after the Effective Date (the “Post-Effective Date Straddle Period”), the portion of such Taxes related to the Pre-Effective Date Straddle Period will be deemed to be:

(i) in the case of income Taxes, franchise and margin Taxes, Taxes measured in whole or in part by reference to gross revenues or receipts, excise, employment, gross receipts and other similar Taxes, sales and use Taxes and Taxes imposed in connection with any sale or other transfer or assignment of property (real or personal, tangible or intangible), equal to the amount that would be

payable if the taxable year of the Company terminated based on an interim closing of the books as of the Effective Date, and based on accounting methods, elections and conventions that do not have the effect of distorting income and expenses; provided that exemptions, allowances or deductions that are calculated on an annual basis (including depreciation and amortization deductions) shall be allocated between the period ending on and including the Effective Date and the period beginning after the Effective Date in proportion to the number of days in each period; and

(ii) in the case of Taxes that are imposed on a periodic basis with respect to the assets or capital of the Companies, equal to the amount of such Taxes for the entire Straddle Period (or, in the case of such Taxes determined on an arrears basis, the amount of such Taxes for the immediately preceding period), multiplied by a fraction, the numerator of which is the number of days during the Straddle Period that are in the Pre-Effective Date Straddle Period and the denominator of which is the number of days in the Straddle Period.

All determinations necessary to give effect to the foregoing allocations will be made in a manner consistent with the past practice of the Companies with respect to such items, unless otherwise required by Applicable Law.

(e) Promptly following the Execution Date, Seller and Buyer shall jointly engage Duff and Phelps to conduct an appraisal and determine the fair market value of the Properties. Seller and Buyer each shall be entitled to participate in the appraisal process and consult with the appraiser. Such appraisal will be completed no later than fifteen (15) days following the Closing Date. The cost of such appraisal shall be divided equally between Seller and Buyer. After the completion of the appraisal, Seller shall prepare an allocation of the Purchase Price and any other items constituting consideration among the Properties in a manner that is consistent with the appraisal and that complies with Section 1060 of the Code and the Treasury regulations promulgated thereunder (the “Allocation”). Seller shall provide such Allocation to Buyer for Buyer’s review and comment prior to finalizing the Allocation. Seller and Buyer shall use commercially reasonable efforts to update the Allocation in a manner consistent with Section 1060 of the Code following any adjustments to the Purchase Price pursuant to this Agreement. Seller and Buyer shall timely file all tax returns, including IRS Form 8594, with the IRS and neither Seller nor Buyer shall take any position in any return that is inconsistent with the Allocation, as adjusted, unless otherwise required to do so by Applicable Law or a final determination as defined in Section 1313 of the Code. Each of Seller and Buyer agree to promptly advise each other regarding the existence of any Tax audit, controversy or litigation related to the Allocation. The Parties recognize that the purchase price allocation may differ for book and tax purposes, and that for book purposes, the purchase price allocation will be based on GAAP requirements.

(f) Seller and Buyer agree to furnish to each other, at the requesting party’s expense, any and all information and documents reasonably required to comply with Tax and financial reporting requirements and audits.

(g) The obligations of Seller in this Section 7.11 shall survive the Closing for a period of thirty (30) days following the applicable statute of limitations.

(h) Any claim for indemnification pursuant to this Section 7.11 shall be made in accordance with the procedures set forth in Section 13.4.

(i) Notwithstanding the foregoing, in no event shall Seller be required to indemnify Buyer under this Section 7.11 with respect to any ad valorem or similar real property Taxes attributable to the period between the Purchase Price Adjustment Date and the Effective Date, and such Taxes shall be the sole responsibility of Buyer.

Section 7.12. Press Releases. Unless consultation is prohibited by Applicable Law, Buyer and Seller shall consult with each other before issuing any press release or otherwise making any public statement with respect to this Agreement or the transactions contemplated hereby and shall not issue any such press release or make any such public statement prior to such consultation (but no approval thereof shall be required).

Section 7.13. Books and Records. At or promptly after Closing, (i) Seller shall deliver to Buyer all records relating to the Business and the Properties that are in Seller’s or its Affiliate’s control, including original minute books and other corporate books and records and accounts and (ii) Seller will deliver to Buyer all of the rights of way easements, rights of way option agreements, files, assignments, operating records and agreements, engineering records, financial and accounting records, and other similar files and records of the Companies which directly relate to the Properties. Buyer agrees that Seller may, subject to the confidentiality obligations in Section 7.7, retain copies of all files transferred to Buyer pursuant to this Section 7.13.

Section 7.14. Rights to “Saddle Butte” Name, Derivations of Name and Logo. Buyer agrees that Seller shall retain all rights to the “Saddle Butte” name, logo, and all derivatives thereof. Within ninety (90) days after the Closing Date, Buyer shall remove all names and markers used by Seller or the Companies and all variations and derivations thereof and logos relating thereto from the Properties.

Section 7.15. Amendments to the Certificates of Formation of the Companies. Immediately after the Closing, Buyer agrees to file an amendment to each Company’s certificate of formation in a form reasonably acceptable to Seller that provides for a change in the name of such Company, which name does not contain the words “Saddle Butte” or any derivative thereof and is otherwise reasonably acceptable to Seller.

Section 7.16. HSR Filing. If compliance with the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Act”), is required in connection with the transactions contemplated under this Agreement, as promptly as practicable and in any event not later than ten (10) Business Days following the Execution Date, Seller and Buyer will file with the Federal Trade Commission and the Department of Justice, as applicable, the required notification and report forms and will as promptly as practicable furnish any supplemental information which may be requested in connection therewith. Seller and Buyer will request expedited treatment (i.e., early termination) of such filing. Buyer and Seller shall use commercially Reasonable Efforts to make or modify all other filings and submissions on a prompt and timely basis in connection with the filings required by this Section. Each of Seller and Buyer will bear its own costs and expenses relating to the compliance with this Section.

Section 7.17. Seller Contracts. The contracts, permits, easements and rights-of-way described on Section 7.17(a) and Section 7.17(b) of the Disclosure Schedule are held by Seller and are used for ownership, operations, maintenance, repair or replacement of the Pipeline and the Facilities (collectively, the “Seller Contracts”). Seller agrees to (a) assign the Seller Contracts to Assets LLC or Berthold Gathering, as applicable, on or before the Closing and (b) use Reasonable Efforts prior to Closing and for a period of not less than one year following the Closing to obtain any consents required therewith. Upon such assignment, the Seller Contracts shall be deemed to be Properties for the purposes of this Agreement. If such Seller Contracts are not assigned to the Companies at Closing, then Seller will cause the Seller Companies to enter into arrangements pursuant to which the benefits of such Seller Contracts are provided by the Seller Companies to the Companies, without cost to Buyer or the Companies; provided, however, that this covenant will survive the Closing and the benefits pursuant to the Seller Contracts listed on Section 7.17(a) of the Disclosure Schedule will be provided by the Seller Companies to the Companies for a period of one (1) year after the Closing Date or such longer period as Seller may agree to.

Section 7.18. High Prairie. After the Closing, Seller shall have the right, but not the obligation, to interconnect with the Pipeline and receive crude oil at up to three locations to be designated by Seller. Should Seller desire to exercise its rights under this Section 7.18, Buyer and Seller shall use good faith efforts to enter into agreements on customary market terms, consistent with industry practice and standards setting forth the terms and conditions of such interconnection. Notwithstanding the foregoing, such agreements shall contain terms no less favorable to Seller than those contained in other interconnection agreements with respect to the Pipeline granted to third parties and to which Buyer is a party. In addition to the foregoing, Buyer shall have the rights set forth in the High Prairie Term Sheet attached hereto as Exhibit 7.18.

Section 7.19. Litigation and Regulatory Cooperation. For a period of nine (9) months following the Closing Date, at the Buyer’s sole cost and expense:

(a) Seller shall cooperate with Buyer in the investigation, defense or prosecution of any Proceedings now in existence or which may arise in the future against or on behalf of the Companies which relate to events or occurrences that transpired or commenced prior to Closing. Seller’s cooperation in connection with such Proceedings shall include, but not be limited to, being available at mutually convenient times and with reasonable advance notice to meet with counsel to prepare for discovery or trial and to act as a witness on behalf of the Company.

(b) Seller shall cooperate with Buyer in any investigation, defense, prosecution or remedial action respecting compliance by the Companies and the Business with regulatory requirements promulgated by applicable Governmental Entities to the extent such investigation, defense, prosecution or remedial action relates to events or circumstances that transpired or commenced prior to Closing.

Section 7.20. Title Policies. Seller shall cooperate with Buyer in obtaining, prior to Closing, an owner’s title insurance policy or leasehold title insurance policy issued by a title company acceptable to Buyer, with respect to the Fee Interests and leased real property interests. The cost of such title insurance policies will be for the account of Buyer. In this connection therewith, Seller shall enter into any customary and reasonable affidavits as may be reasonably required by the title company to issue the title insurance policy to Buyer.

Section 7.21. Financial Statements. Seller shall have prepared by a certified public accounting firm and delivered to Buyer, within 60 days following the Closing (a) financial audits for the Companies and the Business for the years ending December 31, 2012, and 2011, (b) any other financial statements required in connection with the financing efforts or capital markets transactions undertaken by Buyer or its Affiliates or otherwise required by Buyer for financial reporting purposes, and (c) financials required by the Securities and Exchange Commission. Furthermore, Seller shall request the independent public accountants of Seller and the Companies (at Buyer’s expense) to provide any consent necessary to the filing of such financial statements with the Securities and Exchange Commission and to provide such customary representation letters as are necessary in connection therewith.

Article VIII. Buyer’s Due Diligence Examination

Section 8.1. Due Diligence Examination. Each Seller Company shall, through the Title Post-Closing Defect Date as to Title Defects and through the Environmental Post-Closing Defect Date as to Environmental Defects (each such period being an “Examination Period”) afford Buyer and its authorized representatives reasonable access during normal business hours to the records of such Seller Company at the offices of Seller for the purposes of determining whether Title Defects (as defined below) or Environmental Defects (as defined below) exist (“Buyer’s Review”); provided, however, that such investigation shall be upon reasonable notice and shall not unreasonably disrupt the personnel and operations of Seller or such Company or impede the efforts of Seller or such Company to comply with their other obligations under this Agreement. Such books and records shall include files, assignments, operating records and agreements, financial and accounting records, engineering records, in each case insofar as same may now be in existence and in the possession of a Company or Seller or their Affiliates, excluding, however, any information that a Company is prohibited from disclosing by bona fide, third party confidentiality restrictions; provided, that: (i) any information withheld on such basis shall be identified with as much specificity and detail as reasonably possible without breaching such obligation, and (ii) if requested by Buyer, such Company shall use its Reasonable Efforts to obtain a waiver of any such restrictions in favor of Buyer. Subject to the other provisions of this Agreement, Seller shall give Buyer, or Buyer’s authorized representatives, at all reasonable times during the Pre-Closing portion of the Examination Period and upon adequate notice to Seller, physical access to the Properties for the purpose of inspecting same. Furthermore, Seller shall use Reasonable Efforts to cooperate and cause Employees retained by Seller or its Affiliates to cooperate with Buyer in its review during the Post-Closing portion of the Examination Period. The cost and expense of Buyer’s Review, if any, shall be borne solely by Buyer. Buyer shall not, prior to the Closing, contact any of the customers or suppliers of Seller in connection with the transactions contemplated hereby, whether in person or by telephone, mail or other means of communication, without the specific prior authorization of Seller, which consent shall not be unreasonably withheld.

Section 8.2. Assertion of Title and Environmental Defects. If, at any time prior to the Title Post-Closing Defect Date or Environmental Post-Closing Defect Date, as applicable, Buyer discovers any Defects, then the parties shall resolve such Title Defect or Environmental Defect, as applicable, as follows:

(a) Should there be one or more of such Title Defects, Buyer shall notify Seller in writing of such Title Defects as promptly as practicable but in any event, no later than twenty (20) Business Days, after Buyer’s Knowledge of such Defect. Notwithstanding the foregoing, any failure to provide such twenty (20) Business Days notice shall not adversely impact the rights of Buyer with respect to such Title Defect except to the extent such failure materially prejudices Seller. If Buyer determines that it is unwilling to waive a Title Defect, Buyer shall notify Seller in writing of such Title Defects no later than the date that is three (3) months after the Closing Date (the “Title Post-Closing Defect Date”). Such Title Defects of which Buyer so provides notice are herein called “Asserted Title Defects.” In the event that Buyer so notifies Seller of any Asserted Title Defect, Seller shall have the right (but not the obligation) to attempt to cure such Asserted Title Defect to the reasonable satisfaction of Buyer within 90 days (or 180 days if the Asserted Title Defect relates to the Easements described in Section 4.28 of the Disclosure Schedule, provided the term of the Title Defects Escrow shall be extended for the same period as the cure period is extended) after Seller’s receipt of such notice; provided, however, that the exercise of any such right to cure (x) shall be coordinated with Buyer, (y) shall not unreasonably interfere with either Company’s operations or impair the current or future use of the Properties in any material respect and (z) shall not impose any monetary obligations upon Buyer or the Company or any restrictions upon the conduct of the Business (the “Cure Conditions”). All matters that could constitute a Title Defect that are not Asserted Titled Defects are waived by Buyer. At any time prior to the Title Post-Closing Defect Date, if Seller or any Company (prior to Closing) becomes aware of any Title Defect or any allegation by a Person that, if true, would result in a Title Defect, Seller shall as promptly as practicable, but in any event, within twenty (20) Business Days after Knowledge of such Defect (or prior to the Title Post-Closing Defect Date if the Title Post-Closing Defect Date would occur during such twenty Business Day period), notify Buyer in writing of such Title Defect or allegation with respect thereto.

(b) Should there be one or more Environmental Defects, Buyer shall notify Seller in writing of such Environmental Defects as promptly as practicable, but in any event, no later than twenty (20) Business Days after Buyer’s Knowledge of such Defect. Notwithstanding the foregoing, any failure to provide such twenty (20) Business Days notice shall not adversely impact the rights of Buyer with respect to such Environmental Defect except to the extent such failure materially prejudices Seller. If Buyer determines that it is unwilling to waive an Environmental Defect, Buyer shall notify Seller in writing of such Environmental Defects no later than the date that is six (6) months after the Closing Date (the “Environmental Post-Closing Defect Date”). Such Environmental Defects of which Buyer so provides notice are herein called “Asserted Environmental Defects”. In the event that Buyer so notifies Seller of any Asserted Environmental Defect, Seller shall have the right (but not the obligation) to attempt to cure such Asserted Environmental Defect to the reasonable satisfaction of Buyer within 90 days after Seller’s

receipt of such notice, subject to the Cure Conditions. All matters that could constitute an Environmental Defect that are not Asserted Environmental Defects are waived by Buyer. At any time prior to the Environmental Post-Closing Defect Date, if Seller or any Company (prior to Closing) becomes aware of any Environmental Defect or any allegation by a Person that, if true, would result in an Environmental Defect, Seller shall as promptly as practicable, but in any event, within twenty (20) Business Days of Knowledge of such Defect (or prior to the Environmental Post-Closing Defect Date if the Environmental Post-Closing Defect Date would occur during such twenty Business Day period), notify Buyer in writing of such Environmental Defect or allegation with respect thereto.

To be effective, a notice pursuant to this Section 8.2 (“Defect Notice”) must (i) be in writing, (ii) describe the Defect in reasonable detail, (iii) identify the specific Properties to which such Defect relates and (iv) include the Defect Amount (if the Defect can be reasonably estimated) as determined by Buyer in good faith. It being expressly understood that Buyer’s sole and exclusive rights and remedies with respect to any matter that constitutes a Defect shall be those set forth in this Article VIII, and Buyer shall not (absent fraud) be entitled to indemnification or any other right or remedy with respect to any Defect.

Section 8.3. Title Defect Amount. The “Title Defect Amount” resulting from a Title Defect shall be the amount by which the value of the Title Defect Property is reasonably reduced as a result of the existence of such Title Defect and shall be determined in accordance with the following terms and conditions:

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

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

(c) if a Title Defect represents an obligation or Lien upon or other defect in title to the Title Defect Property of a type not described above, the Title Defect Amount shall be determined by taking into account the portion of the Title Defect Property affected by the Title Defect, the legal effect of the Title Defect, the reasonably estimated potential economic effect of the Title Defect over the life of the Title Defect Property, the values and estimated cost to cure placed upon the Title Defect by Buyer and Seller and such other reasonable factors as are necessary to make a proper evaluation; provided, however, that if such Title Defect is reasonably capable of being cured, the Title Defect Amount shall not be greater than the reasonable cost and expense of curing such Title Defect;

(d) if a Title Defect relates to an ownership gap in a right-of-way included in the Property, the Title Defect Amount shall be the reasonable estimated costs and expenses necessary to cure such gap, or alternatively, to construct an alternative route for the pipeline system around such gap, including the cost of acquiring any necessary real property right-of-way and related capital expenditures; and

(e) 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.

Section 8.4. Title Defects. “Title Defect” shall mean (a) a defect exists that causes Seller to not have Defensible Title to all or part of the Pipeline, Easements, Fee Interests or certain Permits (to the extent such Properties are in the nature of a real property interest or an easement or right to use real property) or (b) any inaccuracy in or breach of a representation or warranty contained in Section 4.26 (Preference Rights), Section 4.28 (Easements) and Section 4.31 (Fort Berthold Indian Reservation) to the extent relating to title matters with respect to the Pipeline, Easements, Fee Interests or such Permits. Notwithstanding any other provision in this Agreement to the contrary, the following matters shall not constitute, and shall not be asserted as, a Title Defect: (i) defects or irregularities arising out of lack of corporate authorization or variation in corporate or entity name; (ii) defects or irregularities that have been cured or remedied by the applicable statutes of limitation or statutes for prescription; (iii) defects or irregularities in the chain of title consisting of the failure to recite marital status in documents or omissions of heirship Proceedings; and (iv) Permitted Liens. The fact that the options listed on Section 8.4 of the Disclosure Schedule have not been recorded shall not constitute a “Title Defect” for the purposes of this Agreement.

Section 8.5. Environmental Defects. The term “Environmental Defect” means (a) a situation with respect to or condition of the Properties existing on or prior to the Effective Date that causes such Property (or a Company with respect to such Property) to not be in compliance with or gives rise to liability of a Company under Applicable Environmental Laws or (b) any inaccuracy in or breach of Sections 4.10 or 4.14 to the extent relating to environmental matters. The “Environmental Defect Amount” shall mean the sum of, if any, (i) the amount by which the value of the affected Property is diminished as the result of such Environmental Defect, (ii) the costs and expenses required to be paid to remedy the Environmental Defect, and (iii) any Damages incurred by the Companies as a result of such Environmental Defect (including fines and penalties assessed by Governmental Authorities).

Section 8.6. Certain Pre-Closing Defect Adjustments. If Asserted Title Defects or Asserted Environmental Defects are presented to Seller on or before the fifth (5th) Business Day prior to Closing (the “First Defect Date”), and Seller is unable (or unwilling) to cure to Buyer’s reasonable satisfaction before Closing, then:

(a) Buyer and Seller shall attempt in good faith to agree upon the Defect Amount.

(b) For Asserted Title Defects (i) for which a Defect Notice was given by Buyer on or before the First Defect Date, and (ii) for which the associated reduction has been agreed upon by Buyer and Seller prior to Closing, the Base Purchase Price shall be reduced by the agreed Defect Amount for such Asserted Title.

(c) For Asserted Environmental Defects (i) for which a Defect Notice was given by Buyer on or before the First Defect Date, and (ii) for which the associated reduction has been agreed upon by Buyer and Seller prior to Closing, the Base Purchase Price shall be reduced by the agreed Defect Amount for such Asserted Environmental Defects.

(b) Appropriate adjustments to the Base Purchase Price shall be made between Buyer and Seller through application of the Purchase Price Adjustment Amount so that:

(i) Seller will bear all expenses which are incurred in the operation of the Companies and the Properties before the Purchase Price Adjustment Date and Seller will receive all revenues and all documented reimbursements by the Companies to Seller of amounts expended by Seller prior to the Purchase Price Adjustment Date for continuing the operations of the Companies in the ordinary course of business not reflected in Net Working Capital (net of applicable ad valorem and real property Taxes pursuant to subsection (b)(ii) below) which are attributable to the Companies and the Properties before the Purchase Price Adjustment Date.

(ii) In making such adjustments:

(A) Ad valorem and similar Taxes assessed for periods prior to the Purchase Price Adjustment Date shall be borne by Seller and the ad valorem Taxes assessed for periods on or after the Purchase Price Adjustment Date shall be borne by Buyer;

(B) Ad valorem and similar Taxes assessed with respect to a period which begins before and ends after the Purchase Price Adjustment Date shall be prorated based on the number of days in such period which fall on each side of the Purchase Price Adjustment Date (with the day on which the Purchase Price Adjustment Date falls being counted in the period after the Purchase Price Adjustment Date); and

Section 12.2. Initial Adjustment at Closing. At least five (5) days before the Closing Date, Seller shall provide to Buyer (i) Seller’s good faith estimated balance sheets of the Companies as of 11:59 p.m. local time on the day immediately preceding the Purchase Price Adjustment Date (the “Estimated Purchase Price Adjustment Date Balance Sheet”);

(ii) Seller’s good faith estimate of the Net Working Capital of the Companies (the “Estimated Net Working Capital”) and (iii) Seller’s good faith estimate of the Purchase Price Adjustment Amount (the “Estimated Purchase Price Adjustment Amount”). The Estimated Purchase Price Adjustment Date Balance Sheet, the Estimated Net Working Capital and the Estimated Purchase Price Adjustment Amount (collectively, the “Estimated Closing Items”) shall be prepared in accordance with GAAP applied on a basis consistent with past practice and consistent with the principles and assumptions used in preparation of the audited consolidated balance sheet of Seller as of December 31, 2011 and the Net Working Capital Illustration attached as Exhibit 1.1(b) hereto. Seller shall furnish to Buyer, together with such computations, copies of back-up and other supporting information that reasonably supports such computations. If Buyer disputes Seller’s computations, it shall notify Seller within two (2) Business Days of receipt of the Estimated Closing Items and shall set forth, in reasonable detail, the reasons for such objections. If Buyer fails to give notice of objection within such two (2) Business Day period, then each Company and Buyer shall be deemed to have accepted Seller’s Estimated Closing Items. If Buyer does timely dispute Seller’s computations, Buyer and Seller shall endeavor in good faith to resolve any disputed matters prior to Closing. If Buyer and Seller are unable to so resolve any disputed matters prior to Closing, (A) at Closing, the Purchase Price Adjustment Amount shall be based on Seller’s computation, (B) the dispute resolution provisions of Section 12.3(c) shall be available post-Closing, and (C) any disputed amounts shall be immediately placed in escrow in accordance with the terms of the Escrow Agreement. If the Estimated Purchase Price Adjustment Amount is a positive number, the Base Purchase Price shall be increased by an amount equal to the Estimated Purchase Price Adjustment Amount. If the Estimated Purchase Price Adjustment Amount is a negative number, the Base Purchase Price shall be decreased by an amount equal to the absolute value of the Estimated Purchase Price Adjustment Amount.

Section 12.3. Adjustment Post Closing.

(a) On or before ninety (90) days after Closing, Buyer shall prepare and deliver to Seller (i) balance sheets of the Companies as of 11:59 p.m. local time on the day immediately preceding the Purchase Price Adjustment Date (the “Final Purchase Price Adjustment Date Balance Sheet”); (ii) Buyer’s calculation of the Net Working Capital of the Companies (the “Final Net Working Capital”); and (iii) Buyer’s calculation of the Purchase Price Adjustment Amount (the “Final Purchase Price Adjustment Amount”), in each case, together with a worksheet showing the difference, if any, between any Estimated Closing Item and the corresponding Final Closing Item (as defined below). The Final Purchase Price Adjustment Date Balance Sheet, the Final Net Working Capital and the Final Purchase Price Adjustment Amount (collectively, the “Final Closing Items”) shall be prepared in accordance with GAAP applied on a basis consistent with past practice and consistent with the principles and assumptions used in preparation of the audited consolidated balance sheet of the Companies as of December 31, 2011 and the Estimated Closing Items.

(b) Seller will assist Buyer in the preparation of the Final Closing Items by providing Buyer with any data or information within Seller’s control that is reasonably requested by Buyer. The Final Closing Items shall become final and binding upon the parties on the thirtieth (30th) day following receipt thereof by Seller, unless Seller gives

written notice of its disagreement to Buyer prior to such date. In order to be valid, any such notice shall specify in reasonable detail the dollar amount, nature and basis of any disagreement so asserted. If the Final Purchase Price Adjustment Amount as finally determined pursuant to this Section 12.3 exceeds the Estimated Purchase Price Adjustment Amount, Buyer shall promptly deliver to Seller, by wire transfer of immediately available funds to the account designated by Seller, an amount equal to such excess within five (5) Business Days after the Final Purchase Price Adjustment Date Balance Sheet becomes final. If the Estimated Purchase Price Adjustment Amount exceeds the Final Purchase Price Adjustment Amount as finally determined pursuant to this Section 12.3, Seller shall promptly deliver to Buyer, by wire transfer of immediately available funds to the account designated by Buyer, an amount equal to such excess within five (5) Business Days after the Final Closing Items become final. If the Final Purchase Price Adjustment Amount as finally determined pursuant to this Section 12.3 is equal to the Estimated Purchase Price Adjustment Amount, neither Seller nor Buyer shall have any further obligation under this Section 12.3.

(c) If Buyer and Seller cannot agree upon the Estimated Closing Items or the Final Closing Items, the Dispute shall be submitted to an independent public accounting firm mutually agreed upon by Buyer and Seller (in either case, the “Independent Expert”), which firm shall make a final and binding determination as to all matters in dispute relating to the calculations set forth in the Estimated Closing Items or Final Closing Items as promptly as practicable after its appointment. The Independent Expert shall send its written determination of the adjustments provided for in Section 12.3 and Section 12.3 to Buyer and Seller, together with a calculation of the Final Purchase Price Adjustment Amount that results from such determination, and such determination of the Independent Expert, and the resulting calculations of the adjustments provided for in Section 12.2 and Section 12.3, shall be binding on the parties, absent fraud or manifest error; provided, however, that in no event shall the Independent Expert assign a value to any item greater than the greatest value for such items claimed by either party or less than the smallest value for such items claimed by either party. The fees and expenses of the Independent Expert shall be borne equally by Buyer and Seller.

Section 12.4. No Further Adjustments. Following the adjustments under Section 12.3, no further adjustments shall be made under this Article XII. Should any expenses with regard to the Properties be charged to (or received by) Seller or Buyer after the earlier of (i) the conclusion of such adjustments under Section 12.3 or (ii) ninety (90) days after Closing, the same shall be paid by Buyer, regardless of the periods to which the same relate, and any bills received by Seller will be forwarded to Buyer; provided Buyer shall be entitled to receive a reimbursement of any such payment from the Escrow Account to the extent the amount paid would otherwise have been payable by Seller if known at the time of preparation of the Final Settlement Amount.

(b) Notwithstanding anything to the contrary, it is expressly understood that Seller shall not have any obligation to defend, indemnify and hold harmless Buyer (or its owners, directors, officers, and employees) with respect to any Buyer’s Indemnified Claims made under Section 13.2(a)(i) unless the aggregate of such Buyer’s Indemnified Claims exceeds $10,000,000 (the “Deductible”), and in the event such Buyer’s Indemnified Claims exceed the Deductible, only the value of Damages in excess of the Deductible shall be considered in applying Section 13.2(a)(i), provided, however, that the representations and warranties referenced in Section 13.3(a)(iii) shall not be subject

to the Deductible. In no event shall Seller have liability pursuant to or in connection with any claim under Section 13.2(a)(i) of this Agreement for Damages in excess of $95,000,000 (the “Cap”); provided however, that the representations and warranties referenced in Section 13.3(a)(iii) shall not be subject to the Cap.

Written notice of any claim by Buyer for indemnification from Seller under Section 13.2 arising during the Survival Period must be given by Buyer to Seller as a condition precedent to the right to enforce such claim for indemnification but in any event no later than the end of the Survival Period. Buyer agrees to bring an indemnification claim within ninety (90) days after such claim becomes known to Buyer, provided any failure to do so shall not adversely impact the claim except to the extent of any actual prejudice to Seller. In the event a Buyer’s Indemnified Claim is timely and properly asserted, the covenants set forth in Section 13.2 shall survive until such Buyer’s Indemnified Claim is satisfied, but only with respect to such timely and properly asserted Buyer’s Indemnified Claim.

(c) The applicable survival period for representations and warranties as reflected in Section 13.3(a) above and for covenants reflected in Section 13.3(b) above shall be referred to as the “Survival Period.”

Section 13.4. Notice of Claim. If indemnification pursuant to Sections 13.1 or 13.2 is sought, the party seeking indemnification (the “Indemnitee”) shall give written notice to the indemnifying party of an event giving rise to the obligation to indemnify, describing in reasonable detail the factual basis for such claim, and shall allow the indemnifying party to assume and conduct the defense of the claim or action with counsel reasonably satisfactory to the Indemnitee, and cooperate with the indemnifying party in the defense thereof; provided, however, that the omission to give such notice to the indemnifying party shall not relieve the indemnifying party from any liability which it may have to the Indemnitee, except to the extent that the indemnifying party is prejudiced by the failure to give such notice and as otherwise provided in Section 13.3. The Indemnitee shall have the right to employ separate counsel to represent the Indemnitee if the Indemnitee is advised by counsel that an actual conflict of interest makes it advisable for the Indemnitee to be represented by separate counsel and the reasonable expenses and fees of such separate counsel shall be paid by the indemnifying party.

Section 13.5. No Commissions Owed. Seller agrees to indemnify, defend and hold Buyer (and its partners and its and their Affiliates, and the respective owners, officers, directors, employees, attorneys, contractors and agents of such parties) harmless from and against any and all claims, actions, causes of action, liabilities, damages, losses, costs or expenses (including, without limitation, court costs and attorney’s fees) of any kind or character arising out of or

resulting from any agreement, arrangement or understanding alleged to have been made by, or on behalf of, Seller or a Company with any broker or finder in connection with this Agreement or the transaction contemplated hereby. Buyer agrees to indemnify, defend and hold Seller (and its partners and its and their Affiliates (including without limitation Yorktown Energy Partners VII, L.P., Yorktown Energy Partners VIII, L.P., and Yorktown Energy Partners IX, L.P.) and the respective owners, officers, directors, employees, attorneys, contractors and agents of such parties) harmless from and against any and all claims, actions, causes of action, liabilities, damages, losses, costs or expenses (including, without limitation, court costs and attorney’s fees) of any kind or character arising out of or resulting from any agreement, arrangement or understanding alleged to have been made by, or on behalf of, Buyer, with any broker or finder in connection with this Agreement or the transaction contemplated hereby.

Section 13.6. Net Amounts.Any amounts recoverable by any party pursuant to this Article XIII with respect to any Buyer’s Indemnified Claims or Seller’s Indemnified Claims, as the case may be, shall be decreased by any insurance proceeds or other amounts relating to such Buyer’s Indemnified Claims or Seller’s Indemnified Claims, as the case may be, paid to such Indemnitee by any Person (other than any Affiliate of such Indemnitee) not a party to this Agreement within twenty-four (24) months following the Closing Date.

Section 13.7. Post-Closing Escrow.

(a) Subject to the terms and conditions set forth in this Section 13.7, Buyer shall cause the Indemnity Escrow Amount to be deposited on the Closing Date with the Escrow Agent pursuant to the terms of the Escrow Agreement.

(b) The Indemnity Escrow Amount will be utilized solely to satisfy any indemnification obligations of Seller to Buyer under Section 13.2 and to cover other amounts which can expressly be paid out of the Indemnity Escrow Amount as provided in Section 12.2 in accordance with the terms of this Agreement. The Escrow Agreement shall, subject to paragraph (c) of this Section 13.7, have a term of twelve (12) months commencing on the Closing Date, subject to continuation for disputed claims (the “Indemnity Escrow Term”). The Escrow Agreement shall provide that the Indemnity Escrow Amount may be drawn upon by Buyer, its successors or assigns solely for the purpose of satisfying any indemnification obligations of Seller under Section 13.2 and to cover other amounts which can expressly be paid from the Escrow in accordance with the terms of this Agreement.

(c) If Buyer asserts a claim against the Indemnity Escrow Amount under this Article XIII and Seller does not dispute such claim, Buyer shall be entitled to indemnification by Seller in accordance with this Article XIII, including the right to receive from the Indemnity Escrow Amount funds in an amount equal to the amount of Damages for which Buyer is entitled for such claim under this Article XIII. If, however, Seller disputes such claim, Buyer shall receive the undisputed portion thereof, if any, but shall not be entitled to receive any such disputed portion thereof from the Indemnity Escrow Amount with respect to such claim prior to resolution of such dispute in accordance with Article XVI of this Agreement and, if such dispute extends beyond the expiration of the Indemnity Escrow Term, the term of the Indemnity Escrow Term will be automatically extended as provided in paragraph (d) of this Section 13.7.

(d) Provided the indemnification obligations of Seller for claims of indemnification under this Article XIII of which Seller has been notified prior to the expiration of the Indemnity Escrow Term have been satisfied and no dispute then exists as to any claim for indemnification by Buyer for such claims, the balance of the Indemnity Escrow Amount plus the earned interest and other income will be released to Seller on the first Business Day immediately following the expiration of the Indemnity Escrow Term. To the extent there does exist a claim for indemnification by Buyer of which Seller has been notified, which claim has not been satisfied in full in accordance herewith prior to the expiration of the Indemnity Escrow Term, an amount equal to the reasonable estimate of the amount of such claim hereunder by Seller will be withheld from the balance of the Indemnity Escrow Amount and will continue to be held by the Escrow Agent pursuant to the terms of the Escrow Agreement until such claim has been fully resolved and the Indemnity Escrow Term shall be deemed to be extended accordingly.

(e) The parties shall execute and deliver such instruction notices and letters in writing to the Escrow Agent, and take such other actions, as may be reasonably requested, to implement the terms hereof and to disburse the Indemnity Escrow Amount as contemplated herein.

Article XIV. Casualty Losses

Section 14.1. Casualty Loss. In the event of damage by fire or other casualty to the Properties after the date of this Agreement but prior to the Closing when such casualty losses involve less than five million dollars ($5,000,000.00) and can reasonably be repaired within thirty (30) days and are not otherwise material to the ability of the Companies to conduct the Business, then: (a) this Agreement shall remain in full force and effect; (b) Buyer shall take title to the Property affected by such damage without reduction of the Purchase Price; and (c) Seller shall, at Buyer’s sole election, either (i) assign to Buyer any property damage insurance claims related to such damage and pay any deductibles, or (ii) repair or replace such damaged property to a condition similar to the condition of the affected Property immediately prior to the fire or other casualty and retain all insurance claims and payments with respect thereto.

Section 14.2. Right to Termination. In the event of damages by fire or other casualty to the Properties after the date of this Agreement but prior to the Closing other than a casualty loss referenced in Section 14.1 above, then Buyer may terminate this Agreement by notice to Seller.

Section 14.3. Maintenance of Insurance Coverage. Until the Closing Date, Seller shall maintain the existing insurance coverage, and in the event of a casualty loss which is not covered by insurance, except as provided in this Section, Seller shall have no obligation to Buyer with respect thereto; provided that, if Buyer so requests, and if Seller has not repaired the damage or replaced the affected Property, Seller will assign any rights it may have against third parties with respect to such damage.

Section 16.1. Senior Management Meeting. If a Dispute occurs that the senior representatives of the parties responsible for the transaction contemplated by this Agreement have been unable, in good faith, to settle or agree upon within a period of fifteen (15) days after written notice is given of such Dispute, Seller shall nominate and commit one of its senior officers, and Buyer shall nominate and commit one of its senior officers, to meet at a mutually agreed time and place not later than thirty (30) days after written notice of the Dispute to attempt to resolve same.

If such dispute shall not have been resolved by mediation within thirty (30) days of the initiation of such procedure, or which has not been resolved prior to the termination of mediation, this Agreement does not preclude either party from initiating litigation upon fifteen (15) days written notice to the other party.

Article XVII. Miscellaneous Matters

Section 17.1. Further Assurances. After the Closing, Seller shall execute and deliver, and shall otherwise cause to be executed and delivered, from time to time, such further instruments, notices, division orders, transfer orders and other documents, and do such other and further acts and things, as may be reasonably necessary to more fully and effectively grant, convey and assign the Interests and the Properties to Buyer and the Companies, as applicable.

Section 17.2. Waiver of Consumer Rights. Buyer hereby waives its rights under the Texas Deceptive Trade Practices—Consumer Protection Act, Section 17.41 et seq., Business and Commerce Code, a law that gives consumers special rights and protections, and any similar law in any other state to the extent such Act or similar law would otherwise apply. After consultation with an attorney of Buyer’s own selection, Buyer voluntarily consents to this waiver. To evidence Buyer’s ability to grant such waiver, Buyer represents to Seller that it (a) is in the business of seeking or acquiring, by purchase or lease, goods or services for commercial or business use, (b) has knowledge and experience in financial and business matters that enable it to evaluate the merits and risks of the transactions contemplated hereby, (c) is not in a significantly disparate bargaining position, and (d) has consulted with, and is represented by, an attorney of Buyer’s own selection in connection with this transaction, and such attorney was not directly or indirectly identified, suggested, or selected by Seller or an agent of Seller.

For purposes of the foregoing, actual damages may, however, include indirect, special, consequential, exemplary or punitive damages to the extent (i) the injuries or losses resulting in or giving rise to such damages are incurred or suffered by a Person which is not an Indemnitee pursuant to the Agreement or an Affiliate of such Indemnitee and (ii) such damages are recovered against an Indemnitee by a Person which is not Indemnitee or an Affiliate of such Indemnitee. This Section shall operate only to limit a party’s liability and shall not operate to increase or expand any contractual obligation of a party hereunder or cause any contractual obligation of a party hereunder to survive longer than provided in Section 13.3.

Section 17.4. Transfer Taxes. If this transaction is deemed to be subject to Transfer Tax, for any reason, Seller and Buyer agree to be responsible for such Transfer Taxes on a 50%/50% basis.

EACH PARTY HERETO WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY ACTION, SUIT OR PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT.

Section 17.7. Time of Essence. Time is of the essence in this Agreement.

Section 17.8. No Assignment. This Agreement shall be binding on and inure to the benefit of the parties hereto and their respective successors and assigns, provided that neither party shall have the right to assign this Agreement, including any indemnification rights, or any obligations or benefits hereunder, without the prior written consent of the other party first having been obtained, except that Buyer may assign any or all of its rights and obligations hereunder to an Affiliate of Buyer that is a Delaware limited liability company. Any transfer in absence of such consent shall be null and void.

Purchase and Sale Agreement

EXHIBIT 2.2

Earnout Payment

Earnout. If the Aggregate Average Volume during any Measurement Period included in the Earnout Period equals or exceeds the Base Case Volume for such Measurement Period, Buyer shall pay or cause the Companies to pay to Seller the Earnout Amount by wire transfer of immediately available funds to the account designated by Seller, within ten (10) Business Days after the related Earnout Payment Certificate becomes final in accordance with Section 4 of this Exhibit 2.2. Once paid, the Earnout Amount shall be non-refundable, and the financial condition and results of operations of the Companies during and following the Earnout Period shall not affect Seller’s right to receive and retain the Earnout Amount.

If the Aggregate Average Volume never equals or exceeds the Base Case Volume during any Measurement Period within the Earnout Period, then upon expiration of the Earnout Period, all obligations of the Buyer and the Companies with respect to the Earnout Amount shall lapse and terminate.

Definitions. Capitalized terms used in this Exhibit 2.2 and not otherwise defined shall have the meanings assigned to them in the Agreement. When used in this Exhibit 2.2 or in any other provision of the Agreement, the following terms shall have the respective meanings assigned to them below:

(a)

“Aggregate Average Volume” means the sum of all Inlet Volumes of crude oil during any Measurement Period divided by the number of days in the Measurement Period.

(b)

“Base Case Volume” means the base case “initial volume” for a particular Measurement Period as shown on Annex 2.5.1 hereto.

(c)

“Designated Area” means the counties listed on Annex 2.5.2.

(d)

“Earnout Period” means the period commencing on the Closing Date and ending on June 30, 2014.

(e)

“Inlet Volumes” means all quantities of crude oil received by the Companies at the receipt points on the Pipeline as same is physically extended and expanded during the Earnout Period. For the avoidance of doubt, Inlet Volumes shall include all volumes of crude oil actually available from and offered by producers to Companies at the receipt points on the Pipeline within the Designated Area, but that were not received by the Companies due to a breach by Buyer or a Company (other than due to a force majeure event) of a contractual obligation, provided such volumes will not be double counted for backhauls, extensions or other.

(f)

“Measurement Period” means any calendar month within the Earnout Period.

3.	Operation of Companies. During the Earnout Period,

(a)

The Companies shall, and the Buyer shall cause the Companies to, conduct the activities and operations of the Companies and the Properties in the ordinary course of business of the Companies.

(b)

Neither Company shall enter into any transaction or arrangement with the Buyer or any of its Affiliates that would reasonably be expected to adversely affect the calculation of any Aggregate Average Volume.

(c)

Buyer or any of its Affiliates shall not enter into any transaction or arrangement within the Designated Area that competes with the Companies for crude oil volumes within the Designated Area, to the extent such competition could reasonably be expected to adversely affect the calculation of any Aggregate Average Volume, except that Buyer may acquire other existing midstream assets and businesses and in such case, if Seller in good faith determines that such acquisition adversely influences the Seller’s ability to obtain the Earnout Amount, then Seller may suggest an appropriate adjustment to the Base Case Volume. If an adjustment cannot be mutually agreed upon, then either Seller or Buyer may submit the issue of whether an adjustment is required and the appropriate amount of such adjustment to the Independent Expert. No later than the sixtieth (60^th) day after its appointment, the Independent Expert shall send its written determination of the appropriate adjustment to the Base Case Volume to Buyer and Seller and such determination of the Independent Expert shall be final and binding on the parties, absent fraud or manifest error. The fees and expenses of the Independent Expert shall be borne equally by Buyer and Seller.

4.	Determination of Aggregate Average Volume.

(a)

On or before thirty (30) days after the end of each Measurement Period, Buyer shall prepare and deliver, or cause to be prepared and delivered, to Seller a certificate signed by the chief financial officer, chief accounting officer or any other vice president of finance of Buyer (each an “Earnout Payment Certificate”) setting forth Buyer’s calculation of the Aggregate Average Volume for the Companies for such Measurement Period together with a worksheet showing in reasonable detail the calculation of such amount and copies of back-up and other supporting information that reasonably supports such calculation.

(b)

Buyer shall assist Seller in its review of the Earnout Payment Certificate by providing Seller with any data or information within Buyer’s control that is reasonably requested by Seller, and by providing Seller with reasonable access to management of the Companies. The Earnout Payment Certificate shall become final and binding upon the parties on the thirtieth (30^th) day following receipt thereof by Seller, unless Seller gives written notice of a Dispute based on its disagreement with the Earnout Payment Certificate to Buyer prior to such date. In order to be valid, any such Dispute notice shall specify in reasonable detail the nature and basis of any disagreement so asserted based on Seller’s Knowledge.

Dispute Regarding Earnout Payment Certificate. If Buyer and Seller cannot agree upon any Earnout Payment Certificate, the Dispute shall be submitted to the Independent Expert, which firm shall make a final and binding determination as to all matters in dispute relating to the calculations set forth in the Earnout Payment Certificate as promptly as practicable after its appointment, but in no event later than the thirtieth (30th) day after its appointment. The Independent Expert shall send its written determination of the calculation provided for in this Exhibit 2.2 to Buyer and Seller and such determination of the Independent Expert shall be final and binding on the parties, absent fraud or manifest error. The fees and expenses of the Independent Expert shall be borne equally by Buyer and Seller.
