The Sellers’ Agents shall reasonably cooperate with the Purchaser and its accountants to the extent required to prepare the Final Purchase Price Calculation Statement.

(b)                                  If the Purchaser fails to timely deliver the Final Purchase Price Calculation Statement in accordance with Section 3.7(a), the Sellers’ Agents (on behalf of the Sellers) shall be entitled to retain, at the expense of the Purchaser, a nationally-recognized, independent firm of chartered accountants to provide an audit of the Books and Records of the Acquired Entities and the Subsidiaries (which Books and Records shall be made available by the Purchaser), review the calculation of the Estimated Purchase Price and make any adjustments necessary thereto consistent with the provisions of this Section 3.7 to determine the Closing Working Capital, the Closing Cash, the Closing Indebtedness and the Closing Transaction Expenses, and the determination of such items by the accounting firm shall be final, conclusive and binding on the Parties; provided , however , that the Parties reserve any and all other rights granted to them in this Agreement.

(c)                                   During the period from the date the Final Purchase Price Calculation Statement is delivered by the Purchaser to the Sellers’ Agents through the date the Final Purchase Price Calculation Statement is finally determined in accordance with the terms of this Section 3.7, the Purchaser shall and shall cause each of the Purchaser’s, the Acquired Entities’ and the Subsidiaries’ respective Representatives to reasonably cooperate, during normal working hours and with advance notice, with the Sellers’ Agents and the Sellers’ Agents’ Representatives and to provide the Sellers’ Agents and the Sellers’ Agents’ Representatives access to the work papers of the Purchaser, the Acquired Entities and the Subsidiaries and their respective Representatives to the extent required in connection with their review of the Final Purchase Price Calculation Statement, and the Purchaser shall make available to the Sellers’ Agents, those individuals responsible for the preparation of the Final Purchase Price Calculation Statement in order to respond to inquiries of the Sellers’ Agents related thereto.

(d)                                  If the Sellers’ Agents disagree with any aspect of the Final Purchase Price Calculation Statement, then the Sellers’ Agents shall deliver written notice to the Purchaser (the “ Dispute Notice ”) within thirty (30) days after receipt of the Final Purchase Price Calculation Statement, setting forth, with reasonable particulars, each item with which the Sellers’ Agents disagree and the dollar amounts thereof (each, a “ Disputed Item ”), including the Sellers’ Agents’ position on each Disputed Item (and the Sellers’ Agents’ resulting position on the amount of the Closing Working Capital, Closing Cash, Closing Indebtedness and/or Closing Transaction Expenses, as applicable). Any item set forth in the Final Purchase Price Calculation Statement not objected to by the Sellers’ Agents in the Dispute Notice shall be final, conclusive and binding on the Parties.

(e)                                   If the Sellers’ Agents either (i) notify the Purchaser in writing that the Sellers agree with the Final Purchase Price Calculation Statement within thirty (30) days after receipt thereof or (ii) fails to deliver a Dispute Notice within such thirty (30) day period, the Final Purchase Price Calculation Statement delivered by the Purchaser shall become final, conclusive and binding on

28

the Parties and the Parties shall be deemed to have agreed thereto, in the case of (i), on the date the Purchaser receives such written notice, and in the case of (ii), on such thirtieth (30th) day; provided that, in the event that the Purchaser does not provide, during normal working hours and with advance notice, reasonable access to the work papers and personnel, as requested by the Sellers’ Agents pursuant to Section 3.7(c) within five (5) days of request therefor, such thirty (30) day period shall be extended by one (1) day for each day after the fifth (5 th ) day following such request for the Purchaser to provide such access.

(f)                                    In the event that the Sellers’ Agents deliver a Dispute Notice, the Sellers’ Agents and the Purchaser shall attempt, in good faith, to resolve the Disputed Items within fifteen (15) days after the receipt by the Purchaser of the Dispute Notice and make any amendments to the Final Purchase Price Calculation Statement as mutually agreed to by the Parties.  Any Disputed Items not resolved by the Purchaser and the Sellers’ Agents within such fifteen (15) day period (or such other period as the Parties may agree) shall be submitted to the dispute resolution practice of the Independent Auditor to determine, and such determination shall be final, conclusive and binding on the Parties. The Independent Auditor shall allow the Purchaser and the Sellers’ Agents to present their respective positions regarding the Disputed Items (provided that, for greater certainty, such presentations are limited to the Disputed Items described in the Dispute Notice and that have not been resolved by the Purchaser and the Sellers’ Agents as aforesaid) and each of the Purchaser and the Sellers’ Agents shall have the right to present additional documents, materials and other information, and make an oral presentation to the Independent Auditor, regarding such Disputed Items and the Independent Auditor shall consider such additional documents, materials and other information and such oral presentation. Any such other documents, materials or other information shall be copied to each of the Purchaser and the Sellers’ Agents and each of the Sellers’ Agents and the Purchaser shall be entitled to attend any such oral presentation.

(g)                                   The Independent Auditor shall determine, based solely on such presentations from the Sellers’ Agents and the Purchaser and not by independent review, the unresolved Disputed Items and, acting as experts and not arbitrators, shall render a written report (the “ Adjustment Report ”) to the Sellers’ Agents and the Purchaser in which the Independent Auditor shall set forth, in reasonable detail, the Independent Auditor’s determination with respect to each of the Disputed Items, and the revisions, if any, to be made to the Final Purchase Price Calculation Statement as a result thereof, together with supporting calculations, and the Parties shall make such revisions to the Final Purchase Price Calculation Statement, as applicable. In resolving the Disputed Items, the Independent Auditor: (i) shall be bound to the principles of this Section 3.7 (including the Sample Calculation of Working Capital and related definitions in this Agreement), (ii) shall limit its review and determination to the Disputed Items specifically set forth in the Dispute Notice and submitted to the Independent Auditor for determination and (iii) shall not assign a value to any Disputed Item higher than the highest value for such Disputed Item claimed by either Party or lower than the lowest value for such Disputed Item claimed by either Party. The Parties shall use commercially reasonable efforts to cause the Independent Auditor to complete its work and render the Adjustment Report within thirty (30) days of its engagement. The costs, fees and expenses of the Independent Auditor shall be allocated to and borne by the Purchaser, on the one hand, and the Sellers as a group, on the other hand, (with each Seller responsible only for its Pro Rata Share of the Sellers’ portion) based on the inverse of the percentage that the Independent Auditor’s determination (before such allocation) bears to the total amount of the Disputed Items as originally

29

submitted to the Independent Auditor. For example, should the Disputed Items total in amount to $1,000 and the Independent Auditor awards $600 in favor of the Purchaser’s position, 60% of the costs of the Independent Auditor’s review would be borne by the Sellers as a group (with each Seller responsible only for its Pro Rata Share of such costs) and 40% of the costs would be borne by the Purchaser.

(h)                                  For greater certainty, each of the Closing Working Capital and Estimated Closing Working Capital are to be calculated and prepared in a manner consistent, and in accordance with, the indicative Working Capital calculation set forth in the Sample Calculation of Working Capital.

Section 3.8                                    Payment of Purchase Price Adjustments.

(a)                                  On the fifth (5 th ) Business Day following the date on which the Final Purchase Price Calculation Statement has been determined in accordance with Section 3.7 (whether by agreement of the Parties, deemed agreement or by determination made by the Independent Auditor) (such date, the “ Settlement Date ”), the payments contemplated by Section 3.8(b) shall be made.

(b)                                  On the Settlement Date:

(i)             if the Final Purchase Price is greater than the Estimated Purchase Price, the Purchaser shall pay such surplus amount to the Sellers’ Agents on behalf of the Partnership Sellers, US Blocker Seller and OptionCo Sellers to be distributed to each Partnership Seller, US Blocker Seller and OptionCo Seller in each case in accordance with its respective Pro Rata Share; and

(ii)            if the Final Purchase Price is less than the Estimated Purchase Price, such shortfall shall first be satisfied from the Adjustment Escrow Account, and if the Adjustment Escrow Account is insufficient to cover such shortfall, each Partnership Seller, US Blocker Seller and OptionCo Seller shall pay to the Purchaser its respective Pro Rata Share of such shortfall.

Section 3.9                                    Payments and Location of Closing.

Any reference in this Agreement or in any document delivered pursuant to this Agreement to payment shall mean payment by wire transfer of immediately available funds in Canadian dollars to the bank account or accounts designated by the recipient of such payment in writing to the Purchaser or to the Sellers’ Agents, as the case may be, not less than three (3) Business Days prior to the date of such payment. The Closing shall be held at the offices of Torys LLP, 33rd Floor, 79 Wellington Street West, TD Centre, Toronto, Ontario M5K 1N2 at 10:00 a.m. (Toronto time) on the Closing Date or such other place or time as may be agreed by the Purchaser and the Sellers’ Agents.

Section 3.10                             Withholding Taxes.

(a)                                  Notwithstanding any other provision in this Agreement, the Purchaser and its Affiliates shall be entitled to deduct or withhold any amount from the consideration otherwise payable pursuant to this Agreement to the extent required by the Tax Act or any provision of any

30

other Tax Law. To the extent that the Purchaser or any of its Affiliates deducts or withholds any amount from the consideration payable to the Sellers or Sellers’ Agents pursuant to this Agreement, such withheld or deducted amounts will be treated for all purposes of this Agreement as having been paid to the Sellers or Sellers’ Agents, as the case may be; provided, that the amounts so deducted or withheld are timely remitted to the applicable Taxing Authority. The Purchaser will provide written notice to the Sellers’ Agents, not more than ten (10) Business Days prior to Closing, if the Purchaser determines that any such withholding or deduction is required.

(b)                                  The Acquired Entities shall, and/or shall cause the Subsidiaries to, deduct and withhold from any payments required to be made to current or former directors, officers, employees and consultants or holders of Options pursuant to this Agreement such amounts that are required to be deducted and withheld with respect to the making of such payments under the Tax Act or any provision of any other Tax Law.  To the extent amounts are so withheld, (i) such amounts shall be remitted by the applicable Acquired Entity or Subsidiary to the applicable Taxing Authority, and (ii) the withheld amounts shall be treated for all purposes of this Agreement as having been paid to the current or former director, officer, employee or consultant or holder of an Option in respect of which such deduction and withholding was made.

Section 3.11                             Determination of Pro Rata Share and Cash Pro Rata Share.

Each of the Sellers hereby agrees that, notwithstanding any provision to the contrary in the terms of the Purchased Securities and Governing Documents, its respective Pro Rata Share and Cash Pro Rata Share set forth in Schedule 1(b), as may be amended by the Sellers after the date hereof in accordance with Section 3.1, and any related conversion of Purchased Securities into other classes of Purchased Securities shall be determined based on the Estimated Purchase Price set forth in the Estimated Purchase Price Calculation Statement, and not the final Purchase Price. The terms of the Purchased Securities are hereby automatically amended to give effect to the foregoing, without any further act required on the part of any Seller.

Section 8.10                             GMS Inc. Prospectus Supplement.

GMS Inc. will use commercially reasonable efforts to prepare and file with the SEC prior to the date that is one (1) year from the Closing Date a prospectus supplement (the “ Pro Sup ”) to GMS Inc.’s prospectus dated December 11, 2017, constituting part of the Purchaser’s Registration Statement on Form S-3 (No. 333-221986) (the “ Registration Statement ”), to cover the resale by the Management Equityholders from time-to-time of the Management GMS Shares that they may receive in exchange for their Management Share Consideration. If a Pro Sup to cover the resale by the Management Equityholders from time to time of the Management GMS Shares, has not been prepared and filed prior to the date that is one (1) year from the Closing Date, GMS Inc. will use commercially reasonable efforts to prepare and file with the SEC, as soon as possible, a Pro Sup to cover the resale by the Management Equityholders from time to time of the Management GMS Shares. Notwithstanding the foregoing, GMS Inc. shall not be required to include in the Pro Sup any shares of a Management Equityholder who does not furnish to the Purchaser, within a reasonable time after written request therefor by GMS Inc., such information regarding such Management Equityholder as shall be required as a matter of US or Canadian securities laws.  In the event that securities may not be offered and sold under the Registration Statement pursuant to Rule 415(a)(5) under the US Securities Act of 1933, as amended, (the “ Securities Act ”) while any of the Management GMS Shares to be covered by the Pro Sup or Management Share Consideration

70

have not been disposed of by the Management Equityholders, and GMS Inc. remains eligible to register its securities for sale by the Management Equityholders on Form S-3, GMS Inc. shall use commercially reasonable efforts to prepare and file a replacement registration statement with the SEC and file a prospectus supplement with the SEC covering such shares prior to the time that the Registration Statement ceases to be effective. Such obligation to file successor registration statements and prospectus supplements shall continue so long as any of the Management Share Consideration or, upon the exchange of such shares, the Management GMS Shares, has not been disposed of.  Notwithstanding the foregoing, the obligations of GMS Inc. established in this Section 8.10 shall terminate and shall have no further force or effect at such time as the Management GMS Shares to be covered by the Pro Sup have been sold, or may be sold pursuant to Rule 144(b)(i) of the Securities Act without restriction.

ARTICLE 9

MUTUAL COVENANTS OF THE ACQUIRED ENTITIES AND THE PURCHASER

Section 9.1                                    Regulatory Filings and Other Actions.

(a)                                  In addition to, and not in limitation of the covenants contained in Section 7.3 and Section 8.2, the Acquired Entities and the Purchaser shall prepare and file, as promptly as practicable and (i) in any event within ten (10) Business Days after the execution of this Agreement, the notification required under section 114 of the Competition Act, together with an application for an Advance Ruling Certificate, or, if the Purchaser so decides, an application for an Advance Ruling Certificate alone and (ii) in any event within twenty (20) Business Days after the execution of this Agreement, such other filings, notices and applications required to obtain the consents, approvals and authorizations from Persons and Governmental Authorities that are necessary to consummate the transactions contemplated by this Agreement and the other Transaction Documents.  Each of the Acquired Entities and the Purchaser shall also certify compliance with any supplemental information request under the Competition Act (also known as a ‘supplementary information request’) that it receives within ninety (90) calendar days of receipt of such request.

(b)                                  Each of the Acquired Entities and the Purchaser shall use commercially reasonable efforts to oppose, lift or rescind any injunction or restraining or other order seeking to stop, or otherwise adversely affecting its ability to consummate, this Agreement, the other Transaction Documents and the transactions contemplated hereby or under the other Transaction Documents and to defend, or cause to be defended, any proceedings to which it is a party or brought against it or its directors or officers challenging this Agreement or the consummation of the transactions contemplated hereby or under the other Transaction Documents.

Section 9.2                                    Tax Matters

(a)                                  Tax Returns . The Tax Returns to be filed for the Acquired Entities and the Subsidiaries for Pre-Closing Tax Periods and Straddle Periods, other than Tax Returns filed prior to the Closing Date, will be prepared and filed on a timely basis by the Acquired Entities and the Subsidiaries. Such returns will be prepared consistent with prior practice, except where otherwise required under applicable Laws.  For the avoidance of doubt, either the Purchaser or the Sellers’

71

Agents may cause any Acquired Entity or Subsidiary that is a corporation to make an election pursuant to subsection 256(9) of the Tax Act (and corresponding provincial Law) in respect of the taxation year of such Acquired Entity or Subsidiary, as the case may be, ending on the acquisition of control of it by the Purchaser. The Sellers will cooperate with the Purchaser to effect such filings on a timely basis. The Acquired Entities and the Subsidiaries will timely remit any Taxes shown as owing on such Tax Returns that are owing by the Acquired Entities and the Subsidiaries, as applicable. In respect of Pre-Closing Tax Periods for which original Tax Returns will be filed on or after the Closing Date and in respect of Straddle Periods, the Acquired Entities and the Subsidiaries will deduct the maximum capital cost allowances in respect of depreciable property of the Acquired Entities and the Subsidiaries and the maximum amount of other deductions and reserves as is permitted under the Tax Act.

(b)                                  Allocation of Income or Loss . The Parties agree to cause the Master LP Partnership Agreement and Feeder LP Partnership Agreement to be amended prior to Closing in order to allocate for Tax purposes income, gain, deduction, loss or credit of Master LP and Feeder LP for a Straddle Period to each partner of Master LP and Feeder LP (as applicable) at any time during the Straddle Period (which, for greater certainty, includes a partner at any time in the fiscal period of Master LP and Feeder LP in which the Closing Date occurs) on the basis that the Straddle Period consisted of two hypothetical taxable periods, the first of which ended immediately before the Closing and the second of which began at the Closing, with such income, gain, deduction, loss or credit being allocated between the two hypothetical taxable periods on a “closing of the books basis”, with such income gain, deduction, loss or credit being allocated to the hypothetical taxable period to which they reasonably relate (provided, however, that the exemptions, allowances or deductions that are calculated on an annual basis will be apportioned between the two hypothetical taxable periods on a daily basis). Notwithstanding anything to the contrary herein, (i) the Parties agree to cause the limited partnership agreement governing each partnership of which Master LP is a direct or indirect partner to be amended prior to Closing such that any income, gain, deduction, loss or credit of Master LP in respect of a period shall include its share of any income, gain, deduction, loss or credit of such Subsidiary partnership on the basis that any income, gain, deduction, loss or credit of such subsidiary partnership were allocated on the basis set out in this paragraph, mutatis mutandis , and (ii) except to the extent taken into account in an earlier period, any Transaction Expenses incurred by Master LP or a Subsidiary in respect of the transactions contemplated by this Agreement will be allocated to the first such hypothetical taxable period and, to the extent permitted by the Tax Act and the provisions of any other applicable Tax Law, be deducted or otherwise recognized in computing income in the first such hypothetical taxable period.

(c)                                   Responsibility for Taxes .  The Sellers will be liable for any Taxes of the Acquired Entities under the Tax Act or any other Taxes whatsoever that are in respect of, or attributed to any income earned in, a Pre-Closing Tax Period or the portion of a Straddle Period ending immediately before the Closing except to the extent reflected in the Final Closing Working Capital.  For greater certainty and notwithstanding anything to the contrary herein, the Sellers will be liable for any Taxes payable in respect of a Tax year that is not a Pre-Closing Tax Period by any of the Acquired Entities that is a corporation and that is a partner of Feeder LP, Master LP or any Subsidiary that is a partnership and that relate to such Acquired Entity’s share of any income or gain of Feeder LP, Master LP or any Subsidiary that is a partnership that is allocated to the

72

hypothetical taxable period referenced in Section 9.2(b) that ended immediately prior to the Closing.  The Purchasers will be liable for any all Taxes of the Acquired Entities under the Tax Act or any other Taxes whatsoever that are in respect of, or attributed to any income earned in, the portion of a Straddle Period that began on the Closing Date and all other fiscal and taxable periods ending on or after the Closing. In determining the liability of the Sellers and the Purchasers for Taxes, any bonuses payable to employees which are contingent as of the Closing Date but otherwise incurred or accrued by any Acquired Entity or Subsidiary in a Pre-Closing Tax Period shall be allocated on a daily basis over the period to which such bonuses relate.

(d)                                  Tax Refunds . If the Purchaser, Master LP or any Subsidiary receives any refund of Taxes (in cash or as a reduction of Taxes otherwise due) in respect of any Pre-Closing Tax Period (any such refund, a “ Pre-Closing Tax Refund ”), including for greater certainty, a refund resulting from the recovery of GST/HST in connection with the Closing Transaction Expenses, the Purchaser will calculate the difference between the amount of the Pre-Closing Tax Refund and any amount in respect of the Pre-Closing Tax Refund recorded as an asset in Working Capital. The Purchaser will pay the Sellers’ Agents or their designee (for the benefit of the Sellers) the applicable portion of the amount of the difference, net of any Taxes incurred in respect of the receipt of any refund interest and any costs incurred in respect of such Pre-Closing Tax Refund, by way of wire transfer of immediately available funds within fifteen (15) Business Days of receiving the refund. Any amounts payable under this Section 9.2(d) shall constitute an adjustment in the Purchase Price. Nothing in this Section 9.2(d) shall require that the Purchaser make any payment with respect to any Pre-Closing Tax Refund (and such Pre-Closing Tax Refund shall be for the benefit of the Purchaser) that is the result of the carrying back of any net operating loss, non-capital loss or other Tax attribute or Tax credit incurred or generated in any period other than a Pre-Closing Tax Period.  The Purchaser shall cooperate with the Sellers, to the extent reasonably requested by the Sellers, in obtaining such Pre-Closing Tax Refund, it being understood that any such Pre-Closing Tax Refunds will be claimed in cash rather than as a credit against future Tax liabilities. Any references throughout this Agreement to Taxes for which the Sellers may be liable under Section 9.2(c) include any Taxes that would otherwise result as a refund to the Sellers under this Section 9.2(d).

(e)                                   Actions after Closing . Without the prior written consent of the Sellers’ Agents, which consent may not be unreasonably withheld, conditioned or delayed, the Purchaser will not, and will ensure that no Acquired Entity or Subsidiary or any Affiliate of the Purchaser, any Acquired Entity or any Subsidiary will:

(i)                                      voluntarily approach any Governmental Authority regarding any Taxes or Tax Returns of any Acquired Entity or any Subsidiary for any Pre-Closing Tax Period;

(ii)                                   amend, refile or otherwise modify any Tax Return relating in whole or in part to any Acquired Entity or any Subsidiary with respect to any Pre-Closing Tax Period if such amendment, refiling or modification would reasonably be expected to have an adverse impact on the Sellers;

(iii)                                surrender any claim for material Tax refunds of any Acquired Entity or Subsidiary for any Pre-Closing Tax Period; or

73

(iv)                               except as otherwise required by applicable Tax Law, make or change any Tax elections or change any annual Tax accounting period or adopt or change any method of Tax accounting of any Acquired Entity or any Subsidiary in a manner that results in any material increased Tax liability or any material increase in income or reduction of any deduction, credit or loss carryover, with respect to any Pre-Closing Tax Period if such amendment, refiling or modification would have a material adverse impact on the Sellers.

(f)            Transfer Taxes . All Transfer Taxes shall be borne by the Purchaser. The Purchaser shall timely file, to the extent required by applicable Law, all necessary Tax Returns and other documentation with respect to all such Transfer Taxes and provide to the Sellers’ Agents upon request evidence of payment of all Transfer Taxes.

(g)           Tax Audit .

(i)                                      The Sellers’ Agents, at the Sellers’ sole cost and expense, shall control any audit or other Legal Proceeding in respect of any Tax Return or Taxes of any Acquired Entity or Subsidiary (a “ Tax Contest ”) to the extent it relates solely to Taxes for which the Sellers may be liable under this Agreement; provided, however: (A) the Sellers’ Agents shall keep the Purchaser reasonably informed regarding the status of such Tax Contest and the Purchaser shall be provided copies of any material correspondence relating to such Tax Contest; (B) the Sellers’ Agents shall consult in good faith with the Purchaser regarding the defense of such Tax Contest and the Purchaser shall have the right to participate, or cause the applicable Acquired Entity or Subsidiary to participate, in such Tax Contest; (C) the Sellers’ Agents will provide the Purchaser a reasonable opportunity to comment on any representations or submissions proposed to be made to a Governmental Authority in respect of such Tax Contest and to attend any meeting with any such Governmental Authority with respect to such matters; and (D) the Sellers’ Agents shall not settle, resolve or abandon (and shall not allow any Acquired Entity or any Subsidiary to settle, resolve or abandon) such Tax Contest without the prior written consent of the Purchaser (which shall not be unreasonably withheld, conditioned, or delayed). If the Sellers’ Agents choose not to exercise its right to assume control of a Tax Contest, the Purchaser will provide the Sellers’ Agents a reasonable opportunity to comment on any representations or submissions proposed to be made to a Governmental Authority in respect of such Tax Contest and to attend any meeting with any such Taxing Authority with respect to such matters. If any Governmental Authority is entitled to take collection action in respect of any Tax Contest, notwithstanding the defense relating thereto or if an amount has to be paid in order to advance the Tax Contest, the Sellers shall pay or cause to be paid such amount that is subject to such collection action or that is required to be so paid to the relevant Governmental Authority within the time required by applicable Law. The Sellers shall have the right to pay or cause the applicable Acquired Entity or Subsidiary to pay the

74

balance of the amount subject to a Tax Contest to the relevant Governmental Authority on behalf of the applicable Acquired Entity or Subsidiary.

(ii)                                   The Purchaser will provide notice to the Sellers’ Agents of any inquiries made by any Governmental Authority (including any proposed or actual assessments or reassessments) to the extent that the subject matter thereof would reasonably be expected to give rise to a liability of the Sellers under this Agreement (a “ Tax Claim ”). The Purchaser will forthwith advise the Sellers of the substance of any such inquiries or discussions and provide the Sellers with copies of any material written communications from any Governmental Authority relating to such inquiries or discussions. The failure of the Purchaser to provide any such notice shall not release the Sellers from any of their obligations under this Agreement except to the extent the Sellers are actually materially prejudiced by such failure.

(iii)                                The Sellers and the Purchaser (a) shall cooperate fully with each other and make available to each other in a timely fashion such data, personnel or other information as may reasonably be required to respond to or defend any Tax Contest, (b) shall preserve such data and other information until the expiration of the survival period for the Sellers’ liability for Taxes pursuant to Section 9.2(c), and (c) shall give the other party reasonable advance written notice prior to transferring, destroying or discarding any such information and, if the other Party so requests, the Sellers or the Purchaser, as the case may be, shall allow the other party to take possession of such Books and Records.

(h)           Tax Reporting . Except to the extent required otherwise by applicable Tax Law, the Purchaser and Sellers shall, for all Tax purposes, report the purchase and sale hereunder and the transactions contemplated hereby, in accordance with their form as set out herein, and none of them shall make any available Tax election inconsistent therewith.

(i)            Section 100 Covenants : The Purchaser covenants that within three (3) years following the Closing:

(i)                                      Purchaser Assignee will not become an entity described in any of paragraphs 100(1.1)(a) to (d) of the Tax Act; and

(ii)                                   except pursuant to a sale that is mandated by any Governmental Authority, no interest in any Acquired Entity or Subsidiary that is a partnership will be (A) acquired by a person or partnership described in any of paragraphs 100(1.1)(a) to (d) of the Tax Act, or (B) deemed to be acquired by a person or partnership described in any of paragraphs 100(1.1)(a) to (d) of the Tax Act in connection with a dilution, reduction or alteration of any interest in any such partnership, in either case in a manner that would result in the application of subsection 100(1) of the Tax Act in respect of the sale of all or any portion the Purchased Securities under this Agreement.

75

(j)            Rollover Elections : If requested by a Management Equityholder, the Purchaser and such Management Equityholder shall execute a joint election, where such election is available, under the provision of subsection 85(1) of the Tax Act and the corresponding provisions of any other applicable provincial Law in respect of the sale, assignment, conveyance and transfer of such Management Equityholder’s Purchased Securities to the Purchaser. The “elected amount” for the election will be the amount determined by such Management Equityholder in compliance with the limits set out in subsection 85(1) of the Tax Act or the provisions of any other applicable Law. Such Management Equityholder shall be responsible for preparing the appropriate tax election form; provided that any such election is in a form satisfactory to the Purchaser, acting reasonably, the Purchaser shall execute and return forthwith to such Management Equityholder such election; provided, further, that the Purchaser shall not be responsible for reviewing or otherwise ensuring the proper completion of such election (other than the accuracy of particular information in respect of the Purchaser). Such Management Equityholder shall be solely responsible for filing such election in a timely manner with the appropriate Governmental Authority.

Section 9.3             Non-Competition and Non-Solicitation.

(b)           For a period from the date hereof and continuing for a period of four (4) years from and after the Closing Date, no Seller shall, directly or indirectly, solicit for employment or employ any Key Employee, or request, induce or advise any employee thereof to leave the employ of Master LP or any of the Subsidiaries, without the prior written consent of the Purchaser. Notwithstanding the foregoing, (i) the placement of general advertisements not directed specifically to employees of Master LP or any of the Subsidiaries shall not be deemed to be a solicitation for purposes of this Section 9.3(b) and (ii) no Seller shall be prohibited from employing any Key Employee if such individual ceases to be employed by Master LP or any of the Subsidiaries (other than in connection with a solicitation prohibited hereunder) and such individual has not been employed by Master LP or any of the Subsidiaries for at least six (6) months prior to employment by such Seller(s).

(c)           The Sellers and the Purchaser hereby agree and acknowledge that the duration, scope and geographic areas applicable to the foregoing provisions are fair, reasonable and necessary and that adequate compensation has been received by the Sellers for such obligations.  If, however, for any reason any court determines that any such restrictions are not reasonable or that consideration is inadequate, such restrictions shall be interpreted, modified or rewritten to include as much of the duration, scope and geographic area identified in this Section 9.3 will render such restrictions valid and enforceable.

(d)           The Parties intend that the conditions set forth in subsection 56.4(7) of the Tax Act have been met such that subsection 56.4(5) of the Tax Act applies to any “restrictive covenants”

76

(as defined in subsection 56.4(1) of the Tax Act) granted by each of the Sellers pursuant to this Agreement with respect to the conditions set forth in this Section 9.3, as applicable (the “ Restrictive Covenants ”). For greater certainty, the Parties agree and acknowledge that: (i) for the purposes of paragraph 56.4(7)(d) of the Tax Act, no proceeds shall be received or receivable by the Sellers for granting the Restrictive Covenants; (ii) the Restrictive Covenants are integral to this Agreement and have been granted to maintain or preserve the fair market value of the Purchased Securities; (iii) the Purchaser would not purchase the Purchased Securities without having the benefit of the Restrictive Covenants; and (iv) each of the Sellers is receiving, directly or indirectly, substantial and sufficient consideration pursuant to this Agreement.

Section 9.4             Further Assurances.

From time to time after the date hereof, including any time after the Closing, and without further consideration, if any further action is necessary or desirable to carry out the intent of this Agreement and to fully effect the transactions provided for in this Agreement or any document contemplated hereby (including but not limited to the other Transaction Documents), the Parties shall execute and deliver, or arrange for the execution and delivery of, such other instruments of conveyance and transfer and take or arrange for such other further actions as any other Party may reasonably request.  Each Party shall cooperate affirmatively with the other Parties, to the extent reasonably requested by the other Party to more effectively complete any of the transactions provided for in this Agreement or any document contemplated hereby and to enforce the rights and obligations provided herein.

(v)                                  in no event shall (x) the aggregate liability of any particular Seller for indemnification payable under Article 12 exceed an amount equal to such Seller’s Pro Rata Share of the Purchase Price, taking into account each individual Seller’s Pro Rata Share of the Indemnity Escrow Amount, (y) the liability of an individual Seller for any individual indemnity claims payable under Section 12.2 exceed an amount equal to such Seller’s Pro Rata Share of such indemnity claim, taking into account each individual Seller’s Pro Rata Share of the Indemnity Escrow Amount and (z) any Seller be liable for any portion (Pro Rata Share or otherwise) of any indemnification payable under Section 12.2(ii) as a result of a breach of any representation or warranty or failure to perform of any covenant or agreement of any other Seller, provided that the limitations in (x) and (y) of this Section 12.3(v) shall not apply in respect of any Losses caused by or arising from fraud on the part of the Sellers;

Section 12.6          Notice and Defense of Claims.

(a)           In the event that any Person shall incur or suffer any Losses in respect of which indemnification may be sought by such Person pursuant to the provisions of this Article 12, the Person seeking to be indemnified hereunder (the “ Indemnified Party ”) shall assert a claim for indemnification by written notice to the Person from whom indemnification is sought (the “ Indemnifying Party ”) stating with reasonable specificity the nature and basis of such claim (including the breach, inaccuracy, nonperformance or provision of the Agreement to which such claim relates), a reasonable estimate of the amount of such claim and including copies of all relevant pleadings and other demands (a “ Notice ”). In the case of Losses arising by reason of any claim or Legal Proceeding by a third party (a “ Third Party Claim ”), the Notice shall be given within fifteen (15) days of the filing or other written assertion of any such claim against the Indemnified Party and in all other cases with reasonable promptness, but the failure of the Indemnified Party to give the Notice within such time period shall not relieve the Indemnifying

83

Party of any liability that the Indemnifying Party may have to the Indemnified Party unless the Indemnifying Party can demonstrate actual loss or prejudice as a result of such failure.

(b)           The Indemnified Party shall provide to the Indemnifying Party on request all information and documentation in its possession reasonably necessary to support and verify any Losses which the Indemnified Party believes give rise to a claim for indemnification hereunder and shall give the Indemnifying Party reasonable access to all premises, books, records and personnel in the possession or under the control of the Indemnified Party which would have bearing on such claim.

(c)           In the case of any Third Party Claim (other than for a Tax Claim) for which indemnification is sought, subject to the provisions of this Section 12.6(c), the Indemnifying Party shall have the right to (i) conduct and control any proceedings or negotiations with such third party, (ii) perform and control or direct the performance of any required activities, (iii) take all other steps to settle or defend any such claim (provided that the Indemnifying Party shall not settle any such claim without the consent of the Indemnified Party (which consent shall not be unreasonably withheld, conditioned or delayed) unless the settlement involves only money damages and includes a complete release of the Indemnified Party with respect to the claim, and does not include any statement as to or an admission of fact, culpability, or failure to act, by or on behalf of an Indemnified Party) and (iv) employ counsel at its own cost and expense to contest any such claim or liability. In the event the Indemnifying Party elects to conduct and control any proceedings itself, the Indemnified Party shall be entitled to fully participate at its own cost and expense and by its own separate counsel in any proceedings relating to any third-party claim, except that the Indemnifying Party shall pay the costs and expenses of such separate counsel if (x) in the Indemnified Party’s reasonable judgment, based on the advice of counsel, it is advisable for the Indemnified Party to be represented by separate counsel because a conflict or potential conflict exists between the Indemnifying Party and the Indemnified Party, (y) in the Indemnified Party’s reasonable judgment, based on the advice of counsel, with respect to such claims or liability, the Indemnified Party and the Indemnifying Party may have different, conflicting or adverse legal positions or interests or (z) the named parties to such Third Party Claim include both the Indemnifying Party and the Indemnified Party and the Indemnified Party determines in its reasonable judgment, based on the advice of counsel, that defenses are available to it that are unavailable to the Indemnifying Party.  Notwithstanding anything herein to the contrary, if a Seller is the Indemnifying Party, they shall not have the right to assume the defense and control of any Third Party Claim involving (A) any claim involving breach of representation in Section 4.18 ( Environmental Matters ) relating to any Facility, (B) any claim involving a criminal matter or Legal Proceeding in which the third party is a Governmental Authority,(C) any claim seeking an injunction or other equitable relief or, that in the Indemnified Party’s reasonable judgment, would have a continuing material adverse effect on the Indemnified Party’s business (including any material impairment of its relationships with customers, suppliers or landlords) and (D) a claim which could reasonably be expected to pose significant legal, financial, regulatory or reputational risk to the Indemnified Party.  The Indemnifying Party shall, within thirty (30) days after delivery of the Notice to Indemnifying Party (the “ Dispute Period ”), notify the Indemnified Party in writing of its intention to the conduct and control of the defense of such claim and its acknowledgement and agreement that the Indemnifying Party is responsible for any Losses incurred by the Indemnified Party as a result of such Third Party Claim in accordance with this

84

Article 12, provided , that the Indemnified Party and its counsel shall cooperate with the Indemnifying Party and its counsel.  Until the Indemnified Party has received notice of the Indemnifying Party’s election whether to defend any claim, the Indemnified Party shall take reasonable steps to defend (but may not settle) such claim.  If the Indemnifying Party shall decline to assume the defense of any such claim, or the Indemnifying Party shall fail to notify the Indemnified Party within the Dispute Period of the Indemnifying Party’s election to defend such claim, the Indemnified Party shall defend against such claim (provided that the Indemnified Party shall not settle such claim without the consent of the Indemnifying Party (which consent shall not be unreasonably withheld, conditioned or delayed)). The expenses (including attorneys’ fees and expenses) of all proceedings, contests or lawsuits in respect of such claims shall be borne by the Indemnifying Party but only if the Indemnifying Party is responsible pursuant hereto to indemnify the Indemnified Party in respect of the Third Party Claim and, if applicable, only to the extent required by Section 12.3 and Section 12.5, as the case may be, and subject to the limitations of this Section 12.6 and Section 12.7. Regardless of whether the Indemnified Party or the Indemnifying Party shall assume the defense of the claim, the Indemnified Party and the Indemnifying Party agree to cooperate fully with one another in connection therewith and to keep each other reasonably informed of the status of the claim and any related proceeding and the Indemnified Party shall take no action or make any admissions or statements not required by applicable Law which would adversely affect the defense of any such claim.

(d)           If the Indemnifying Party notifies the Indemnified Party that it does not dispute its liability to the Indemnified Party with respect any claim under this Article 12 or fails to notify the Indemnified Party within the Dispute Period, the Losses arising from any such claim shall, subject to the provisions of Section 12.3, Section 12.5 and Section 12.7, be conclusively deemed a liability of the Indemnifying Party and the Indemnifying Party shall, subject to the provisions of Section 12.3, Section 12.5 and Section 12.7, pay the amount of such Loss to the Indemnified Party on demand following the final determination thereof. If the Indemnifying Party has timely disputed its liability with respect to such claim, the Indemnifying Party and the Indemnified Party shall proceed in good faith to negotiate a resolution of such dispute and, if not resolved through negotiations, either party may seek a resolution of such dispute by litigation in a court of competent jurisdiction in accordance with Section 14.10 and Section 14.11.

Section 12.7          Further Limitations and Qualifications on Indemnification.

(a)           Damages . Notwithstanding anything herein to the contrary, the Indemnified Party shall have no right to indemnification with respect to (i) any punitive, exemplary or special damages or (ii) any Losses (other than Losses in respect of Taxes) to the extent not a reasonably foreseeable result of any breach by the Indemnifying Party of a representation and warranty or covenant contained in this Agreement.

(b)           Tax Benefit or Loss .

(i)                                      The Indemnifying Party shall be entitled to any Tax Benefit realized by the Indemnified Party or any of its Affiliates as a consequence of any Loss or Taxes (including any circumstance giving rise to such Loss or Taxes) that the Indemnifying Party or any of its affiliates is responsible for under this

85

Agreement (including, for the avoidance of doubt, pursuant to Article 12). Unless such Tax Benefit cannot be claimed directly by the Indemnifying Party, the Indemnified Party shall claim (or shall cause its relevant subsidiary or affiliate to claim) such Tax Benefit and pay to the Indemnifying Party the amount of such Tax Benefit within fifteen (15) days after such Tax Benefit is realized.

(ii)                                   Any amounts payable by an Indemnifying Party to or on behalf of an Indemnified Party with respect to any Loss or Taxes pursuant to Section 12.3 shall be increased to take account of any net Tax cost incurred by the Indemnified Party or any of its Affiliates arising from the receipt of indemnity payments hereunder (grossed up for such increase). The amount of any Loss or Taxes for which indemnification is provided hereunder and the amount of any such Tax cost on the receipt of indemnity payments shall be determined net of any item of loss, deduction, credit or other Tax asset or attribute arising in or attributable to any Pre-Closing Tax Period available to reduce the amount of any Tax liability.

(c)           Right to Recover . The Indemnifying Party shall make any indemnification payments determined to be payable to the Indemnified Party hereunder without regard to any expectation that the Indemnified Party (including, for this Section 12.7(c) in the case of the Purchaser, the Acquired Entities and the Subsidiaries) will recover insurance proceeds (including under the R&W Policies) or other amounts (whether by payment, discount, credit, relief, insurance or otherwise) as a result of the matter giving rise to the claim for which indemnification payments are to be made. In addition, the Indemnifying Party shall, to the extent of any indemnification payment made by it, be subrogated to all rights of the Indemnified Party against any third party in respect of the claim to which the indemnification payment relates. If the Indemnified Party receives any insurance proceeds (including under the R&W Policies) or other amounts as a result of the matter giving rise to any indemnification claim of the Indemnified Party prior to the date upon which the Indemnifying Party is given notice of the claim, the Indemnifying Party’s indemnification obligation with respect to such claim shall be reduced by the amount of any such insurance proceeds actually received by the Indemnified Party (including under the R&W Policies). If the Indemnified Party receives any insurance proceeds (including under the R&W Policies) or other amounts as a result of the matter giving rise to any indemnification claim of the Indemnified Party against the Indemnifying Party after the Indemnifying Party has paid such indemnification claim to the Indemnified Party, then the Indemnified Party shall promptly turn over any such insurance proceeds or other amounts received to the Indemnifying Party to the extent of the payments made by the Indemnifying Party to the Indemnified Party on the claim; provided , however , that with respect to any such insurance proceeds received by the Indemnified Party under the R&W Policies, the Indemnified Party shall only be responsible to turn over amounts received with respect to such claim that were in excess of the Deductible to the extent that the Deductible applied to such claim.

(d)           Exclusive Remedies .  Subject to the rights of the Parties pursuant to Section 14.6, from and after Closing, except with respect to matters covered by Section 3.7, the sole recourse and exclusive remedy of the Purchaser Indemnified Parties and the Seller Indemnified Parties arising out of this Agreement, the other Transaction Documents or the transactions contemplated

86

hereunder or thereunder, whether based on tort, contract, statutory or common law remedy or equitable remedy or otherwise, including any misrepresentation, breach of warranty, non-fulfillment or failure to perform a covenant or agreement or otherwise, shall be to assert a claim for indemnification under the indemnification provisions of this Article 12 and the Purchaser and the Sellers each covenant that it (and the Indemnified Parties) will not seek to obtain any remedy except as provided in this Article 12.

(e)           Duration of Claim . The indemnification obligations of the Indemnifying Party pursuant to this Agreement with respect to a specific claim for which indemnification is provided under this Agreement shall extend beyond the time period for indemnification set forth herein with respect to such specific claim until it has been fully discharged or resolved or settled provided that  a Notice shall have been given to the Indemnifying Party on or prior to the end of such time period.

(f)            Mitigation of Losses . The Indemnified Party shall take commercially reasonable steps to mitigate any Losses upon and after becoming aware of any event, fact or circumstance which would reasonably be expected to give rise to Losses.

(g)           Contingent Liabilities .  No Indemnifying Party shall be liable under this Article 12 in respect of any Loss which is contingent unless and until such contingent Loss becomes an actual liability and is due and payable; provided , however , that an Indemnified Party shall not be prohibited from asserting a claim for indemnification hereunder in respect of any contingent Losses, and such claim, if otherwise made timely in accordance with this Article 12, will survive until finally resolved pursuant to this Article 12.

(h)           GPco Sellers . No indemnification shall be payable by any GPco Seller pursuant to this Article 12.

Section 12.8          Indemnification Adjustment to Purchase Price.

To the fullest extent permitted under applicable Law, any amounts payable under this Article 12 shall constitute an adjustment in the Purchase Price.

Section 12.9          Indemnity Procedure.

To the extent that there is any inconsistency between Section 9.2 ( Tax Matters ), on the one hand, and Section 12.6 and Section 12.7, on the other hand, as it relates to any Tax Contest, the provisions of Section 9.2 ( Tax Matters ) shall govern.
