     (a) Estimated Purchase Price. No later than five (5) Business Days prior to the Closing Date, the Representative shall deliver to Buyer a calculation of the Estimated Purchase Price and the components thereof, together with reasonable supporting detail, and based on the Company’s books and records and other information then available. The Estimated Purchase Price shall be reasonably acceptable to Buyer. On the Closing Date, Buyer shall pay, or shall cause to be paid, the Estimated Purchase Price as follows:

The portion of the Estimated Purchase Price not otherwise allocated pursuant to clauses (i) and (ii) of this Section 2.3(a) (i.e., that will consist of McJ Units) shall be paid in accordance with the Contribution Agreement.

     (b) Preparation of the Final Statement of Purchase Price.

Expenses (the “Proposed Company Expenses”), and, in each case, the components thereof, together with reasonable supporting detail.

     (ii) If the Representative does not give a written notice of dispute (a “Purchase Price Dispute Notice”) to Buyer within thirty (30) days after receiving the Proposed Purchase Price Calculation, Buyer and the Representative agree that (A) the Proposed Net Working Capital shall be deemed to set forth the Net Working Capital, (B) the Proposed Cash and Cash Equivalents shall be deemed to set forth the Cash and Cash Equivalents, (C) the Proposed Debt Amount shall be deemed to set forth the Debt Amount, (D) the Proposed Company Expenses shall be deemed to set forth the Company Expenses and (E) the Proposed Purchase Price Calculation shall be deemed to be final and binding in determining the Purchase Price.

The “Final Statement of Purchase Price” shall mean the Proposed Purchase Price Calculation together with any revisions thereto pursuant to this Section 2.3(b)(ii).

     (iv) Buyer will make the Company’s financial records available to the Accounting Firm and the Representative and his accountants and other representatives at reasonable times at any time during the review by the Representative and/or the Accounting Firm, as the case may be, of, and the

     (C) McJ Holding will issue additional McJ Units to the Continuing Shareholders in accordance with Exhibit B with an aggregate value (determined based on the price per McJ Unit to be paid under the Contribution Agreement) equal to the product of (x) the Positive Adjustment Amount plus the Escrow Amount and (y) the Aggregate Contribution Percentage.

     (ii) If the Actual Adjustment is a negative amount (the absolute value of such negative amount, the “Negative Adjustment Amount”) and the Negative Adjustment Amount is less than the Escrow Amount:

     (A) Buyer and the Representative will instruct the Escrow Agent to pay (1) to the Representative on behalf of the Shareholders for distribution to the Shareholders in accordance with their respective Cash Proceeds Percentages set forth on Exhibit B, an amount, if any, equal to the product of (x) the Escrow Amount minus the Negative Adjustment Amount and (y) 100% minus the Aggregate Contribution Percentage, net of applicable withholding taxes, if any, out of the Escrow Account by wire transfer or delivery of other immediately available funds within three (3) Business Days after the date on which the Purchase Price is finally

determined pursuant to Section 2.3(b), and (2) to Buyer the remaining amount of the Escrow Funds out of the Escrow Account by wire transfer or delivery of other immediately available funds within three (3) Business Days after the date on which the Purchase Price is finally determined pursuant to Section 2.3(b); and

     (c) No material liability under Subtitle C or D of Title IV of ERISA has been or is expected to be incurred by the Company or any of its Subsidiaries with respect to any ongoing, frozen or terminated Company Benefit Plan or with respect to the single-employer plan of any entity which is considered one employer with the Company or any of its Subsidiaries under Section 4001 of ERISA or Section 414 of the Code (an “ERISA Affiliate”). Other than the Company and its Subsidiaries, neither the Company nor any of its Subsidiaries has any ERISA Affiliates nor any liability with respect to any entity that previously was an ERISA Affiliate.

No Benefit Plan is under audit, investigation or similar proceeding by the IRS, the Department of Labor, the Pension Benefit Guarantee Corporation or any other Governmental Entity and, to the Knowledge of the Company, no such audit, investigation or proceeding is pending. Neither the Company

nor any of its Subsidiaries has any obligations for retiree health or life benefits under any ERISA Plan or collective bargaining agreement or has obligations to any Employee (either individually or Employees as a group) that such Employee(s) would be provided with such retiree health or life benefits upon their retirement or termination of employment, except to the extent required by Section 4980B of the Code.

     (e) Neither the execution and delivery of this Agreement, nor the consummation of the transactions contemplated hereby will (x) entitle any Employees to severance pay or any material increase in severance pay upon any termination of employment after the date hereof, or (y) accelerate the time of payment or vesting, or result in any payment or funding (through a grantor trust or otherwise) of compensation or benefits under, or increase the amount payable, or result in any other material obligation pursuant to, any of the Benefit Plans or (z) result in the triggering or imposition of any restrictions or limitation on the right of the Company or any of its Subsidiaries to amend or terminate any Benefit Plan.

     (f) Except for such Benefit Plans set forth on Schedule 4.8(f), none of the Benefit Plans, if administered in accordance with their terms, could result in the imposition of interest or an additional tax on any participant thereunder pursuant to Section 409A of the Code.

     4.9. Compliance with Laws. The businesses of the Company and each of its Subsidiaries have not been, and are not being, conducted in violation of any applicable Law, except for violations that, individually or in the aggregate, are not reasonably likely to have a Material Adverse Effect. Except with respect to regulatory matters covered by Section 6.2, no investigation or review by any Governmental Entity with respect to the Company or any of its Subsidiaries is pending or, to the Knowledge of the Company, threatened, nor has any Governmental Entity indicated an intention to conduct the same, except for those the outcome of which are not, individually or in the aggregate, reasonably likely to have a Material Adverse Effect. To the Knowledge of the Company, no material change is required in the Company’s or any of its Subsidiaries’ processes, properties or procedures in connection with any such Laws, and none of the Company or any of its Subsidiaries has received any notice or communication of any material noncompliance with any such Laws that has not been cured as of the date hereof.

As of the date hereof, no event has occurred which, with or without notice, lapse of time or both, would constitute a default on the part of Buyer under the Financing Commitments and as of the date hereof Buyer has no reason to believe that any of the conditions to the Financing contemplated by the Financing Commitments will not be satisfied or that the Financing will not be made available to Buyer. Subject to the terms and conditions contained in this Agreement and the Financing Commitments, Buyer will have at the Closing funds sufficient to pay the cash portion of the Estimated Purchase Price (and any repayment or refinancing of debt contemplated by this Agreement or the Financing Commitments) and any other amounts

required to be paid in connection with the consummation of the transactions contemplated hereby, and to pay all related fees and expenses.

     (a) Cooperation. Subject to the terms and conditions set forth in this Agreement, each Party shall cooperate with each other and use (and the Company shall cause its Subsidiaries to use) their respective commercially reasonable efforts to take or cause to be taken all actions, and do or cause to be done all things reasonably necessary, proper or advisable on its part under this Agreement and applicable Laws to consummate and make effective the transactions contemplated by this Agreement as soon as practicable, including preparing and filing as promptly as practicable all documentation to effect all necessary notices, reports and other filings and to obtain as promptly as practicable all consents, registrations, approvals, permits and authorizations necessary or advisable to be obtained from any third party and/or any Governmental Entity in order to consummate the transactions contemplated by this Agreement. Without limiting the foregoing, Buyer will, as soon as practicable after the date of this Agreement, (i) prepare and file any Notification and Report Forms and related material required

     (c) Status. Subject to applicable Laws and the instructions of any Governmental Entity, the Company and the Shareholders shall keep Buyer, and Buyer shall keep the Company and the Representative, apprised of the status of matters relating to completion of the transactions contemplated hereby, including promptly furnishing such Parties with copies of notices or other communications received by such Party, as the case may be, or any of its Subsidiaries, from any third party and/or any Governmental Entity, including under the HSR Act and the Competition Act, with respect to the transactions contemplated by this Agreement. The Company and the Shareholders shall give prompt notice to Buyer of any change, fact or condition that is reasonably likely to result in a Material Adverse Effect or of any failure of any condition to Buyer’s obligations to effect the Closing and Buyer shall give prompt notice to the Company and the Representative of any change, fact or condition that is reasonably likely to have a material adverse effect on Buyer’s ability to consummate the Financings or of any failure of any condition to the Company’s obligations to effect the Closing; provided, however, that the delivery of any notice pursuant to this sentence shall not limit or otherwise affect the remedies available hereunder to the Party to which such notice is given.

     6.3. Access and Reports. Subject to applicable Law, upon reasonable notice, the Company shall (and shall cause each of its Subsidiaries to) afford Buyer’s officers, its financing sources and other authorized representatives of Buyer reasonable access, during normal business hours throughout the period prior to the Closing, to its employees, properties, books, Contracts and records and, during such period, the Company shall (and shall cause each of its Subsidiaries to) furnish promptly to Buyer all information concerning its business, properties and personnel as may reasonably be requested, provided that no investigation pursuant to this Section 6.3 shall affect or be deemed to modify any representation or warranty made by the Company or the Shareholders herein, and provided, further, that the foregoing shall not require the Company (i) to permit any inspection, or to disclose any information, that in the reasonable judgment of the Company would result in the disclosure of any trade secrets of third parties or violate any of its

obligations with respect to confidentiality or (ii) to disclose any privileged information of the Company or any of its Subsidiaries. All requests for information made pursuant to this Section 6.3 shall be directed to the Representative or other Person designated by the Representative. All such information shall be governed by the terms of the Confidentiality Agreement.

     6.4. Shareholder Restrictions. From the date of this Agreement to the Closing, except as necessary to comply with Sections 6.17 and 6.18, each of the Shareholders agrees it shall not (a) sell, transfer, encumber, assign or otherwise dispose of, or enter into any Contract with respect to the sale, transfer, encumbrance, assignment or other disposition of, any of the Company Stock held by such Shareholder or (b) take any action (other than any action required by Law), or omit to take any action (other than any action prohibited by Law), which would reasonably be expected to have the effect of preventing or disabling such Shareholder from delivering such Shareholder’s Company Stock to Buyer or McJ Holding at the Closing, or immediately prior to Closing, free and clear of any Encumbrances or otherwise performing such Shareholder’s obligations under this Agreement or the Contribution Agreement.

     6.5. Shareholder Non-Compete Agreements. At or prior to the Closing, the Company and each Person listed on Schedule 6.5 shall enter into a Non-Compete and Non-Solicitation Agreement in the form attached hereto as Exhibit G (each, a “Non-Compete Agreement”).

     6.6. Shareholders’ Post-Closing Confidentiality Obligation. Each Shareholder acknowledges that (i) during the course of its affiliation with the Company, it has produced and/or had access to confidential information relating to the Company and its Subsidiaries (“Confidential Information”), and (ii) the unauthorized use or disclosure of any Confidential Information at any time would constitute unfair competition with Buyer and would deprive Buyer of the benefits of this Agreement and the transactions contemplated by this Agreement. Each Shareholder agrees that it will hold in confidence the Confidential Information and will not, directly or indirectly, disclose, publish, or otherwise make available any of the Confidential Information to the public or to any Person or use any of the Confidential Information for its own benefit or for the benefit of any other Person, other than Buyer and its Affiliates; provided, however, that such Shareholder may disclose Confidential Information if, but only to the extent, required to do so by Law, provided, however, that in such case, such Shareholder shall provide Buyer with prior written notice thereof so that Buyer may seek an appropriate protective order or other appropriate remedy, and such Shareholder shall (at Buyer’s expense) reasonably cooperate with the Company in connection therewith and provided, further, that, in the event that a protective order or other remedy is not obtained, such Shareholder shall furnish only that portion of such information which, in the opinion of its counsel, such Shareholder is legally compelled to disclose and shall exercise commercially reasonable efforts to obtain reasonable assurance that confidential treatment will be accorded any such information so disclosed.

     6.7. Release of Claims by Shareholders. Effective upon the Closing, each of the Shareholders, on such Shareholder’s own behalf and on behalf of such Shareholder’s heirs, executors, administrators, legal representatives, successors and assigns, hereby irrevocably releases, acquits, and forever discharges the Company and the Company’s Subsidiaries and each of their respective present or former officers, directors, agents, employees, employee benefit plans (and the fiduciaries thereof) and Affiliates, in each case, in their capacity as such, and the successors and assigns of any of the foregoing (collectively, the “Released Parties”), from any

and all claims, actions, causes of action, suits, rights, debts, agreements, damages, injuries, losses, costs, expenses, (including legal fees) and demands whatsoever and all consequences thereof, of every nature or description, whether known or unknown, suspected or unsuspected, foreseen or unforeseen, actual or potential, existing as of or prior to the Closing, that any of the Shareholders ever had, now has or may in the future (as of or prior to the Closing) have against any of the Released Parties, in law or in equity, as a result of any act, transaction, agreement, event or omission, occurring or committed from the beginning of time through the Closing (the “Released Claims”), other than (i) any claims for current wages, benefits and expense reimbursements arising in the ordinary course of business or (ii) any other claims that constitute current liabilities of the Company and its Subsidiaries and the amount of which are taken in the computation of Net Working Capital. Notwithstanding the foregoing, any obligation by Buyer or the Company to any Shareholder to be performed after the Closing pursuant to this Agreement or any of the Ancillary Documents shall not constitute a Released Claim.

     6.8. Investigations and Actions. The Shareholders and the Company shall keep Buyer informed, on a current basis, of any events, discussions, notices or changes with respect to any criminal or regulatory investigation or action involving the Company or any of its Subsidiaries, so that Buyer and its Affiliates will have the opportunity to take appropriate steps to avoid or mitigate any regulatory consequences to them that might arise from such investigation or action.

     6.9. Indemnification; Directors’ and Officers’ Insurance.

     (a) From and after the Closing the Company will indemnify and hold harmless, to the fullest extent permitted under applicable Law (and the Company shall also advance expenses as incurred to the fullest extent permitted under applicable Law provided the Person to whom expenses are advanced provides an undertaking to repay such advances if it is ultimately determined that such Person is not entitled to indemnification), each present and former director, officer and employee of the Company or any of its Subsidiaries (collectively, the “Company Indemnified Parties”) against any costs or expenses (including reasonable attorneys’ fees), judgments, fines, losses, claims, damages or liabilities incurred in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, arising out of or pertaining to matters existing or occurring at or prior to the Closing; provided, however, that the Company shall not indemnify any director, officer or employee for any liability for (i) receipt of a financial benefit to which such Company Indemnified Party is not entitled, (ii) an intentional infliction of harm on the Company or its Affiliates, (iii) in the case of a director, a distribution in violation of Section 1052 of the Oklahoma General Corporation Act or Section 2030 of the Oklahoma Limited Liability Company Act or (iv) an intentional violation of criminal Law.

     (b) Any Company Indemnified Party wishing to claim indemnification under Section 6.9(a) upon learning of any such claim, action, suit, proceeding or investigation, shall promptly notify the Company thereof, but the failure to so notify shall not relieve the Company of any liability it may have to such Company Indemnified Party except to the extent such failure materially prejudices the indemnifying party. In the event of any such claim, action, suit, proceeding or investigation (whether arising before or after the Closing), (i) the Company shall have the right to assume the defense thereof and the Company shall not be liable to such Company Indemnified Parties for any legal expenses of other counsel or any other expenses

subsequently incurred by such Company Indemnified Parties in connection with the defense thereof, except that if the Company elects not to assume such defense or counsel for the Company Indemnified Parties advises that there are issues which raise conflicts of interest between the Company and the Company Indemnified Parties, the Company Indemnified Parties may retain counsel satisfactory to them, and the Company shall pay all reasonable fees and expenses of such counsel for the Company Indemnified Parties promptly as statements therefor are received; provided, however, that Company shall be obligated pursuant to this Section 6.9(b) to pay for only one firm of counsel for all Company Indemnified Parties in any jurisdiction unless the use of one counsel for such Company Indemnified Parties would present such counsel with a conflict of interest; provided that the fewest number of counsels necessary to avoid conflicts of interest shall be used; (ii) the Company Indemnified Parties will cooperate in the defense of any such matter; and (iii) the Company shall not be liable for any settlement effected without the Company’s prior written consent; and provided, further, that the Company shall not have any obligation hereunder to any Company Indemnified Party if and when a court of competent jurisdiction shall ultimately determine, and such determination shall have become final, that the indemnification of such Company Indemnified Party in the manner contemplated hereby is prohibited by applicable Law. If such indemnity is not available with respect to any Company Indemnified Party, then the Company and the Company Indemnified Party shall contribute to the amount payable in such proportion as is appropriate to reflect relative faults and benefits to the extent permitted by applicable Law.

     (c) Prior to the Closing, Buyer shall obtain and fully pay for “tail” insurance policies with a claims period of at least six years from and after the Closing from an insurance carrier with the same or better credit rating as the Company’s current insurance carrier with respect to directors’ and officers’ liability insurance and fiduciary liability insurance with benefits and levels of coverage at least as favorable as the Company’s existing policies with respect to matters existing or occurring at or prior to the Closing (including in connection with this Agreement or the transactions or actions contemplated hereby); provided, however, that in no event shall Buyer or the Company be required to expend for such policies an annual premium amount in excess of 200% of the annual premiums currently paid by the Company for such insurance; and provided, further, that if the annual premiums of such insurance coverage exceed such amount, Buyer or the Company shall obtain a policy with the greatest coverage available for a cost not exceeding such amount.

     (d) If the Company or any of their respective successors or assigns (i) shall consolidate with or merge into any other corporation or entity and shall not be the continuing or surviving corporation or entity of such consolidation or merger or (ii) shall transfer all or substantially all of its properties and assets to any individual, corporation or other entity, then, and in each such case, proper provisions shall be made so that the successors and assigns of the Company shall assume all of the obligations set forth in this Section 6.9.

     (e) The provisions of this Section 6.9 are intended to be for the benefit of, and shall be enforceable by, each of the Company Indemnified Parties.

     (f) The rights of the Company Indemnified Parties under this Section 6.9 shall be in addition to any rights such Company Indemnified Parties may have under the certificate of

incorporation or bylaws of the Company or any of its Subsidiaries, or under any applicable Contracts or Laws.

     6.10. Director Resignations. The Shareholders shall cause the Company to deliver to Buyer, written letters of resignation, effective on or prior to the Closing, of each of the directors and officers of the Company and its Subsidiaries requested by Buyer prior to the Closing.

     6.11. Excluded Assets. Prior to the Closing, the Company shall cause the assets set forth on Schedule 6.11 to be transferred in accordance with such Schedule.

     6.12. Ancillary Documents. On or prior to the Closing, the Shareholders shall cause the Representative to execute and deliver, and Buyer shall execute and deliver, the Escrow Agreement.

     6.13. Financing.

     (a) Buyer shall use its reasonable best efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things necessary, proper or advisable to arrange the Debt Financing on the terms and conditions described in the Debt Financing Commitment (provided that Buyer may replace or amend the Debt Financing Commitment to add lenders, lead arrangers, bookrunners, syndication agents or similar entities which had not executed the Debt Financing Commitment as of the date hereof, or otherwise so long as the terms would not materially adversely impact the ability of Buyer to consummate the transactions contemplated hereby or the likelihood of consummation of the transactions contemplated hereby), including using reasonable best efforts to (i) maintain in effect the Debt Financing Commitment, (ii) satisfy on a timely basis all conditions applicable to Buyer to obtaining the Debt Financing set forth in the Debt Financing Commitment (including by consummating the equity financing pursuant to the terms of the Equity Financing Commitment), (iii) enter into definitive agreements with respect thereto on the terms and conditions contemplated by the Financing Commitments or on other terms that would not adversely impact the ability or likelihood of Buyer to consummate the transactions contemplated hereby, and (iv) consummate the Financing at or prior to the Closing. If any portion of the Debt Financing becomes unavailable on the terms and conditions contemplated in the Debt Financing Commitment, Buyer shall use its reasonable best efforts to arrange to obtain alternative financing from alternative sources in an amount sufficient to consummate the transactions contemplated by this Agreement as promptly as practicable following the occurrence of such event; provided, that such alternative financing shall be on terms and conditions materially no less favorable to Buyer than those provided in the Debt Financing Commitment, or otherwise on terms and conditions acceptable to Buyer. Buyer shall give the Company prompt notice of any material breach by any party to the Financing Commitments of which Buyer becomes aware, or any termination of the Financing Commitments. Buyer shall keep the Company informed on a reasonably current basis in reasonable detail of the status of its efforts to arrange the Debt Financing and provide copies of all documents related to the Debt Financing (other than any fee letters and ancillary documents subject to confidentiality agreements) to the Company. The Company hereby consents to the use of its and its Subsidiaries’ names and logos in connection with the Financing.

     (b) Prior to the Closing, the Company shall, and the Shareholders shall cause the Company to, provide to Buyer, and shall cause its Subsidiaries to, and shall use its reasonable best efforts to cause the respective officers, employees and advisors, including legal and accounting, of the Company and its Subsidiaries to, provide to Buyer all cooperation reasonably requested by Buyer that is necessary in connection with the Debt Financing, including using reasonable best efforts to (i) participate in meetings, presentations, road shows, due diligence sessions and sessions with rating agencies, (ii) provide assistance in preparation of confidential information memoranda (including execution and delivery of a customary representation letter) and other materials to be used in connection with obtaining financing contemplated by the Debt Financing Commitment and all information (including financial information) customarily contained therein, (iii) provide assistance in the preparation for, and participate in, meetings, due diligence sessions and similar presentations to and with, among others, prospective lenders, investors and rating agencies, (iv) enter into a loan agreement and related documents (including pledge and security documents), (v) execute and deliver customary certificates, legal opinions or other documents reasonably requested by Buyer (including a certificate of the chief financial officer of the Company with respect to solvency matters) and otherwise reasonably facilitate the pledging of collateral contemplated by the Debt Financing Commitment (including taking all actions reasonably necessary to (A) permit the prospective lenders involved in the Debt Financing to evaluate the Company’s current assets, cash management and accounting systems, policies and procedures relating thereto for the purpose of establishing collateral arrangements and to conduct the appraisals and field examinations relating thereto as contemplated by the Debt Financing Commitment and (B) establish bank and other accounts and blocked account agreements and lock box arrangements in connection with the foregoing) and (vi) provide the financial statements and other information necessary for the satisfaction of the obligations and conditions set forth in the Debt Financing Commitment within the time periods required thereby in order to permit a Closing Date on or prior to the Termination Date; provided, however, that nothing herein shall require such cooperation to the extent it would interfere unreasonably with the business or operations of the Company or any of its Subsidiaries. The Company shall use its reasonable best efforts to obtain pay-off letters, in form and substance reasonably satisfactory to Buyer, from holders of all Debt and to ensure that each such pay-off letter will provide for the waiver of any notice provisions relating thereto. If this Agreement is terminated pursuant to Section 8.1(a) or 8.1(b)(ii) (but with respect to Section 8.1(b)(ii) only for a Willful or Deliberate Breach by Buyer), Buyer shall, promptly upon request by the Company, reimburse the Company for all reasonable and documented out-of-pocket costs incurred by the Company or its Subsidiaries in connection with such cooperation.

     6.14. CanHCo Call Right. The Parties agree that during the period from June 15, 2008 to December 15, 2008 (the “Call Period”), Buyer may, in its sole discretion, cause Red Man Pipe & Supply Canada Ltd, a wholly owned Subsidiary of the Company (“CanHCo”), to exercise the CanHCo Call Right set forth in Section 10 of the Midfield Shareholders Agreement. If Buyer so elects to exercise the CanHCo Call Right, then no later than five (5) Business Days following payment of the CanHCo Call Price to Midfield Holdings (Alberta) Ltd. (“MinorityHCo”) or any of its Permitted Transferees (as defined in the Midfield Shareholders Agreement), Buyer shall pay by wire transfer of immediately available funds to the Representative, on behalf of the Shareholders, for distribution to the Shareholders in accordance with Schedule 1, to an account designated by the Representative in a written notice to Buyer, an amount in cash equal to (i) $99,954,281.63 minus (ii) the sum of (x) the CanHCo Call Price (in U.S. Dollars using the

spot rate at the close of business on the Business Day immediately prior to the day the CanHCo Call right is exercised) paid by CanHCo to MinorityHCo or any of its Permitted Transferees (as defined in the Midfield Shareholders Agreement) and (y) all costs, charges, fees, expenses, losses, liabilities, obligations, claims, fines, Transfer Taxes and other Taxes imposed on CanHCo, the Company or any of their Affiliates as a result of the exercise of the CanHCo Call Right or the consummation of such transaction (in U.S. Dollars using the spot rate at the close of business on the Business Day immediately prior to the day the CanHCo Call right is exercised), including the amount equal to the aggregate principal amount, plus accrued interest thereon, of all shareholder loans which are repaid by CanHCo as contemplated by Section 10(e) of the Midfield Shareholders Agreement except to the extent such amounts were included in the Debt Amount (the difference of (i) and (ii), as may be set off pursuant to Section 2.3(c), “Midfield Amount”). If Buyer elects not to cause CanHCo to exercise the CanHCo Call Right, then on or prior to the one month anniversary of the expiration of the Call Period, Buyer shall pay by wire transfer of immediately available funds to the Representative, on behalf of the Shareholders, for distribution to the Shareholders in accordance with the column entitled “Cash Proceeds Percentages” on Exhibit B, to an account designated by the Representative in a written notice to Buyer, an amount in cash equal to the Midfield Amount determined as if Buyer exercised the CanHCo Call Right on the final day of the Call Period. If the CanHCo Call Right is exercised and the Midfield Amount is a negative amount, the Non-Plan Shareholders shall, severally and not jointly, pro rata in proportion to each such Shareholder’s ownership of shares of Company Stock in accordance with the column entitled “Non-Plan Shareholders Percentages” on Schedule 1, be liable to Buyer for the absolute value of such negative amount. Any payments made under this Section 6.14 shall be considered an adjustment to the Purchase Price.

     6.15. Assets of Buyer. The Shareholders and the Company hereby acknowledge and agree that (a) as of the date hereof, (i) Buyer’s sole assets are cash in a de minimis amount and its rights under this Agreement and the agreements contemplated hereby, and (b) no additional funds are expected to be contributed to Buyer unless and until the Closing occurs.

     6.16. Phantom Stock. Prior to Closing, the Shareholders shall cause the Company to cancel all of the phantom stock awards held by ▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇▇ and ▇▇▇▇ ▇▇▇▇ solely in consideration for the Shareholders’ obligation to pay such individuals cash or other property at such time or times and in such amounts as may be agreed before the Closing Date, and which payments shall not constitute “parachute payments” within the meaning of Section 280G of the Code, in each case, as reasonably acceptable to Buyer.

     6.17. Contribution Percentages. Each Shareholder agrees that Exhibit B under the heading “Contributed Shares” sets forth for such Shareholder the minimum number of shares of Company Stock that such Shareholder shall contribute to McJ Holding as Contributed Shares pursuant to the Contribution Agreement. The Parties agree that the Representative may, no later than 15 Business Days prior to the Closing Date, deliver a written notice to Buyer (the “Contribution Percentage Notice”) changing the number of shares of Company Stock to be contributed pursuant to the Contribution Agreement by any ▇▇▇▇▇▇▇ Entity, or adding BJHK Living Trust, CK and/or any Other ▇▇▇▇▇▇▇ Entity that holds shares of Company Stock as a Continuing Shareholder; provided that (i) the CK Contributed Share Percentage shall in no event be less than 25% or greater than 50% and (ii) the aggregate number of Contributed Shares shall not exceed 30,996.30 (that is, an Aggregate Contribution Percentage of 17.38%). The Parties

agree that Exhibit B shall be amended prior to the Closing to reflect any change in the number of Contributed Shares or any additional Person contributing shares of Company Stock pursuant to the Contribution Percentage Notice. In addition, (x) BJHK Living Trust shall execute and deliver the Contribution Agreement prior to Closing if its number of Contributed Shares as adjusted pursuant to this Section 6.17 is greater than zero and (y) each of CK and each Other ▇▇▇▇▇▇▇ Entity shall execute and deliver the Contribution Agreement and this Agreement as a Shareholder prior to Closing if it is added as an additional Person contributing shares of Company Stock pursuant to the Contribution Percentage Notice; provided that if BJHK Living Trust or such CK or Other ▇▇▇▇▇▇▇ Entity fails to execute and deliver the Contribution Agreement and/or this Agreement, as applicable, its number of Contributed Shares shall be zero.

     10.7. Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the state of Delaware without giving effect to the principles of conflicts of law.

     10.8. Amendments and Waivers. No amendment or waiver of any provision of this Agreement shall be valid unless the same shall be in writing and signed by the Company, the Representative and Buyer. No waiver by any Party of any default or any breach of any representation, warranty, covenant or agreement hereunder or under any Ancillary Document shall be deemed to extend to any prior or subsequent default or breach or affect in any way any

rights arising by virtue of any such prior or subsequent occurrence. Notwithstanding the foregoing, (a) this Agreement may be amended to add additional Persons as “Shareholders” to reflect changes in the ownership of Company Stock prior to the Closing as contemplated by Section 6.17 and (b) Exhibit B may be amended as contemplated by Section 6.17.

     10.9. Severability. If any provision of this Agreement for any reason shall be held to be illegal, invalid or unenforceable, such illegality shall not affect any other provision of this Agreement, this Agreement shall be amended so as to enforce the illegal, invalid or unenforceable provision to the maximum extent permitted by applicable Law, and the parties shall cooperate in good faith to further modify this Agreement so as to preserve to the maximum extent possible the intended benefits to be received by the Parties.

     10.10. Construction. The Parties intend that each representation, warranty, covenant and agreement contained in this Agreement or in any Ancillary Document shall have independent significance. If any Party has breached any representation, warranty, covenant or agreement contained herein in any respect, the fact that there exists another representation, warranty, covenant or agreement relating to the same subject matter (regardless of the relative levels of specificity) which the Party has not breached shall not detract from or mitigate the fact that the Party is in breach of the first representation, warranty, covenant or agreement.

     10.11. Specific Performance. The Company and each of the Shareholders acknowledge and agree that Buyer would be damaged irreparably in the event any of the provisions of this Agreement or any of the Ancillary Documents is not performed in accordance with its specific terms or otherwise is breached by the Company or any of the Shareholders. Accordingly, the Company and each of the Shareholders agree that Buyer shall be entitled to an injunction or injunctions to prevent breaches of this Agreement or any Ancillary Document by the Company or any of the Shareholders and to enforce specifically the terms and provisions of this Agreement and each Ancillary Document, this being in addition to any other remedy to which Buyer is entitled at law or in equity. In addition, Buyer agrees that the Company and the Shareholders shall be entitled to an injunction or injunctions to prevent breaches of this Agreement by Buyer and to enforce specifically the terms and provisions of this Agreement, this being in addition to any other remedy to which the Company and the Shareholders are entitled at law or in equity, but the Company and the Shareholders shall be entitled to such injunction or injunctions solely to prevent breaches of or to enforce compliance with (x) Sections 6.2, 6.9, 10.1 and 10.4 and (y) those covenants of Buyer contained in Section 2.3(a), only if the proceeds of the financing provided for in the Debt Financing Commitment (and, if alternative debt financing is being used in accordance with Section 6.13(a), the proceeds of the financing contemplated by such alternative debt financing) are available to be drawn down by Buyer pursuant to the terms of the applicable agreements but is not so drawn down solely as a result of Buyer refusing to do so in breach of this Agreement.

     10.12. Jurisdiction; Court Proceedings; Waiver of Jury Trial. Any Claim against any Party to this Agreement arising out of or relating to this Agreement shall be brought in any federal or state court located in the State of Delaware located in the County of New Castle and each of the parties hereby submits to the exclusive jurisdiction of such courts for the purpose of any such Claim. A final judgment in any such Claim shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by Law. To the

extent that service of process by mail is permitted by applicable Law, each Party irrevocably consents to the service of process in any such Claim in such courts by the mailing of such process by registered or certified mail, postage prepaid, at its address for notices provided for herein. Each Party irrevocably agrees not to assert (a) any objection which it may ever have to the laying of venue of any such Claim in any federal or state court located in the State of Delaware in the County of New Castle and (b) any claim that any such Claim brought in any such court has been brought in an inconvenient forum. Each Party waives any right to a trial by jury, to the extent lawful, and agrees that any of them may file a copy of this paragraph with any court as written evidence of the knowing, voluntary and bargained-for agreement among the Parties irrevocably to waive its right to trial by jury in any Claim whatsoever between them relating to this Agreement or the transactions contemplated hereby.

     10.13. Attorneys’ Fees. In the event that any action or proceeding is brought for the purpose of determining or enforcing the right of any Party or Parties hereunder, the Party or Parties prevailing in such action or proceeding shall be entitled to recover from the other Party or Parties all reasonable costs and expenses incurred by the prevailing Party or Parties, including reasonable attorneys’ fees.

     10.14. Representative.

     (a) By the execution and delivery of this Agreement, including counterparts hereof, each Shareholder hereby irrevocably constitutes and appoints ▇▇▇▇▇ ▇▇▇▇▇▇▇ as the true and lawful agent and attorney-in-fact of such Shareholder with full powers of substitution (the “Representative”), and, if substituted, the Representative shall promptly notify Buyer of such substitution, to act in the name, place and stead of such Shareholder with respect to this Agreement, as the same may be from time to time amended, and with respect to the transfer of such Shareholder’s Company Stock to Buyer pursuant hereto and the transactions contemplated hereby, and to do or refrain from doing all such acts and things, and to execute all such documents, as the Representative shall deem necessary or appropriate in connection with this Agreement, the Ancillary Documents or any of the transactions contemplated hereby or thereby. In the event of the death or other incapacity of the then current Representative, or resignation of the Representative, Shareholders which on the date hereof hold a majority of the Company Stock, shall, by any writing executed by the appropriate number of Shareholders and the new Representative (counterparts and facsimiles of signatures acceptable) approve and appoint a new Representative by delivering a written notice to that effect, whereupon the person designated in such notice shall be the new Representative with respect to all actions taken and/or documents signed from and after actual receipt by Buyer of such notice.

     (b) Without limiting the generality of the foregoing, the Representative is hereby authorized (i) to receive any payment owing to the Shareholders pursuant to Section 2.3, (ii) to execute the Escrow Agreement on behalf of the Shareholders, and (iii) to take all actions on behalf of the Shareholders in connection with any actions taken or to be taken under Section 2.3 of this Agreement (including accepting service of process upon the Shareholders and accepting or compromising any claim relating to the Proposed Purchase Price Calculation). The Representative and the Shareholders hereby agree that any amounts disbursed out of the Escrow Account to the Representative pursuant to the terms of this Agreement and/or the Escrow

Agreement shall be distributed by the Representative to the Shareholders in accordance with Schedule 1 and Exhibit B, as applicable. All decisions and actions of the Representative permitted hereunder shall be final, binding and conclusive on the Shareholders and may be relied upon by Buyer and its Affiliates as the decisions and actions of all of the Shareholders. The Representative shall not be liable to any of the Shareholders for any act done or omitted by him in good faith pursuant to this Agreement or any mistake of fact or Law unless caused by his own gross negligence or willful misconduct, and the Shareholders shall jointly and severally indemnify the Representative from any Losses arising out of his serving as Representative hereunder. In taking any action or refraining from taking any action whatsoever the Representative shall be protected in relying upon any notice, paper or other document reasonably believed by him to be genuine, or upon any evidence reasonably deemed by him to be sufficient. The Representative may consult with counsel in connection with his duties and shall be fully protected in any act taken, suffered or permitted by him in good faith in accordance with the advice of counsel.

This Agreement shall not confer any rights or remedies upon any Person other than the Parties, the Company Indemnified Parties, the Buyer Indemnitees and McJ Holding and its Affiliates (including its members and Subsidiaries) under Section 10.4, and their respective successors and permitted assigns. The Parties further agree that the rights of the Company Indemnified Parties under Section 6.9 shall not arise unless and until the Closing occurs.

     10.16. Obligations of Parties. Whenever this Agreement requires a Subsidiary of the Company to take any action, such requirement shall be deemed to include an undertaking on the part of the Company and the Shareholders to use reasonable best efforts to cause such Subsidiary to take such action.

     10.17. No Presumption Against Drafting Party. Each Party acknowledges that each Party has been represented by counsel in connection with this Agreement, each of the Ancillary Documents and the transactions contemplated herein and therein.
