(a) From and after the Distribution Date, without duplication, each of Parent and SpinCo shall be responsible for, and shall pay its respective share of, the liability for Taxes of Parent, SpinCo and their respective Affiliates, as provided in this Agreement. Parent shall indemnify and hold harmless SpinCo and its Affiliates from any Taxes for which Parent is responsible under this Agreement. SpinCo shall indemnify and hold harmless Parent and its Affiliates from any Taxes for which SpinCo is responsible pursuant to this Agreement.

(c) any increase in the U.S. federal, state, local or foreign Income Tax liability of Parent, SpinCo or any member of either of their respective Groups with respect to any Pre-Distribution Tax Period, but only if, and then to the extent that, such increased Income Tax liability is attributable to either (i) SpinCo’s willful misconduct or material breach of its obligations under this Agreement or (ii) a change in any item of income, gain, deduction, loss, credit or other allowance from that which was reported on, or omitted from, an Income Tax Return as originally filed for a Pre-Distribution Tax Period, whether that change arises from a Tax Contest, amended Tax Return, claim for refund or otherwise, that increases the amount of income or gain attributable to SpinCo or any SpinCo Affiliate in a Pre-Distribution Tax Period and correspondingly decreases the amount of income or gain attributable to SpinCo or any SpinCo Affiliate in a Post-Distribution Tax Period or that decreases the amount of deductions, losses, credits or other allowances attributable to SpinCo or a SpinCo Affiliate in a Pre-Distribution Tax Period and correspondingly increases the amount of deductions, losses, credits or other allowances attributable to SpinCo or any SpinCo Affiliate in a Post-Distribution Tax Period;

(e) any stamp, sales, use, gross receipts, value-added, withholding, real estate transfer or other similar Taxes imposed in connection with the Transactions.

Section 2.4 Payment of Allocable Taxes.

(a) With respect to each payment of Tax that is due after the Distribution Date in connection with the filing of any Tax Return, including estimated tax installments and payments made in connection with extension requests, the party responsible for filing such Tax Return under Article III shall notify the other party in writing of the amount of the tax sharing payment due from such other party, if any, calculated under the principles of this Agreement, and such other party shall make its tax sharing payment to the first party (to the extent not previously paid or credited); provided, however, that neither party shall be required to make a tax sharing payment to the other party under this Section 2.4(a) until five (5) days after the applicable Tax payment is made to the applicable Taxing Authority. Tax sharing payments made under this Section 2.4(a), as well as tax sharing payments made by, or credited to, a party prior to the Distribution Date, shall be adjusted when each applicable Tax Return and the calculation of the applicable Tax liability is finalized.

(b) If any Tax Return for a Pre-Distribution Tax Period is examined by a Taxing Authority and such examination results in additional Taxes due, the party responsible for such additional Taxes under Section 2.2 or 2.3, as applicable, shall pay or cause its Affiliate to pay the indemnified amount to the other party within five (5) days after such other party makes payment of such additional Taxes following a Final Determination.

(c) Section 2.4(a) shall not apply to any payment of foreign Income Tax that is due after the Distribution Date in connection with the filing of any SpinCo Separate Return for any Straddle Period. Rather, within sixty (60) days after the Distribution Date, Parent shall provide a statement to SpinCo containing a reasonably detailed estimate of the amount of such foreign Income Taxes attributable to the portion of the Straddle Period ending on the Distribution Date. Parent and SpinCo shall cooperate with each other in good faith to reach agreement on such estimated amount within thirty (30) days after Parent provides such statement to SpinCo. Within five (5) days after the estimated amount is finally determined by agreement of the parties or pursuant to Article VI, Parent shall pay such finally determined amount to SpinCo. There shall be no “true up” or other adjustment payable by, or refundable to, Parent when the Straddle Period foreign Income Tax Returns described in this Section 2.4(a) are finalized and filed, and Parent shall not be liable for any additional foreign Income Taxes due, and shall not be entitled to receive

any refunds of foreign Income Taxes, resulting from any amendment to, or Tax Contest involving, SpinCo Separate Returns for any Straddle Period, except to the extent that any such additional Taxes due are attributable to Parent’s willful misconduct or material breach of its obligations under this Agreement. For the avoidance of doubt, this Section 2.4(c) does not apply to Income Tax Returns of Acuity Canada for the Straddle Period.

Section 2.5 Allocation of Certain Income Taxes and Income Tax Items.

(a) If Parent, SpinCo or any of their respective Affiliates is permitted but not required under applicable Tax laws to treat the Distribution Date as the last day of a taxable period, then the parties shall treat such day as the last day of a taxable period under such applicable Tax law and shall file any elections necessary or appropriate to such treatment, provided that this Section 2.5(a) shall not be construed to require Parent to change its taxable year.

(b) Transactions occurring, or actions taken, on the Distribution Date but after the Distribution outside the ordinary course of business by, or with respect to, SpinCo or any of its Affiliates shall be deemed subject to the “next day rule” of Treasury Regulation Section 1.1502-76(b)(1)(ii)(B) (and under any comparable or similar provision under state, local or foreign laws or regulations, provided that if there is no comparable or similar provision under state, local or foreign laws or regulations, then the transaction will be deemed subject to the “next day rule” and as such shall for purposes of this Agreement be treated (and consistently reported by the parties) as occurring in a Post-Distribution Tax Period of SpinCo or a SpinCo Affiliate, as appropriate).

(c) Any Taxes for a Straddle Period shall, for purposes of this Agreement, be apportioned between the portion of the period ending on and including the Distribution Date and the portion of the period beginning after the Distribution Date, and each such portion of such period shall be deemed to be a taxable period (whether or not it is in fact a taxable period). Any allocation of income or deductions required to determine any Income Taxes for a Straddle Period shall be made by means of a closing of the books and records of SpinCo and its Affiliates as of the close of business on the Distribution Date, provided that (i) Parent may elect to allocate Tax Items (other than any extraordinary Tax Items) ratably in the month in which the Distribution occurs (and if Parent so elects, SpinCo shall so elect) as described in Treasury Regulations Section 1.1502-76(b)(2)(iii) and corresponding provisions of state, local, and foreign Tax laws; and (ii) subject to clause (i), exemptions, allowances or deductions that are calculated on an annual basis, and not on a closing of the books method (including, but not limited to, depreciation and amortization deductions) shall be allocated between the period ending on and including the Distribution Date and the period beginning after the Distribution Date based on the number of days for the portion of the Straddle Period ending on and including the Distribution Date, on the one hand, and the number of days for the portion of the Straddle Period beginning after the Distribution Date, on the other hand.

(d) Tax attributes determined on a consolidated or combined basis for taxable periods ending before or including the Distribution Date shall be allocated to Parent and its Affiliates, and SpinCo and its Affiliates, in accordance with the Code and the Treasury

Regulations (and any applicable state, local, or foreign law or regulation). Parent shall reasonably determine the amounts and proper allocation of such attributes. Parent and SpinCo agree to compute their Tax liabilities for taxable periods after the Distribution Date consistent with that determination and allocation, and treat the Tax Items as reflected on any federal (or applicable state, local or foreign) Income Tax Return filed by the parties as presumptively correct.

Section 2.6 Tax Refunds. Except as provided in Section 2.7:

(a) Parent shall be entitled to all refunds (including refunds paid by means of a credit against other or future Tax liabilities) and credits with respect to any Tax for which Parent is responsible under this Agreement. SpinCo shall be entitled to all refunds (including refunds paid by means of a credit against other or future Tax liabilities) and credits with respect to any Tax for which SpinCo is responsible under this Agreement.

(b) Parent and SpinCo shall each forward to the other party, or reimburse such other party for, any refunds received by the first party and due to such other party pursuant to this Section. Where a refund is received in the form of a credit against other or future Tax liabilities, reimbursement with respect to such refund shall be due in each case on the due date for payment of the Tax against which such refund has been credited. All payments made pursuant to this Section 2.6 shall describe in reasonable detail the basis for the calculation of the amount being paid.

(c) If one party reasonably so requests, the other party (at the first party’s expense) shall file for and pursue any refund to which the first party is entitled under this Section, provided that the other party need not pursue any refund on behalf of the first party unless the first party provides the other party a certification by an appropriate officer of the first party setting forth the first party’ s belief (together with supporting analysis) that the Tax treatment of the Tax Items on which the entitlement to such refund is based is more likely than not correct, and is not a Tax Item arising from a Reportable Transaction.

(d) If the other party pays any amount to the first party under this Section 2.6 and, as a result of a subsequent Final Determination, the first party is not entitled to some or all of such amount, the other party shall notify the first party of the amount to be repaid to the other party, and the first party shall then repay such amount to the other party, together with any interest, fines, additions to Tax, penalties or any other additional amounts imposed by a Taxing Authority relating thereto.

Section 2.7 Carrybacks.

(a) Notwithstanding anything in this Agreement, SpinCo shall file (or cause to be filed) on a timely basis any available election to waive the carryback of net operating losses, Tax credits or other Tax Items by SpinCo or any Affiliate from a Post-Distribution Tax Period to a Straddle Period or Pre-Distribution Tax Period.

(b) If, notwithstanding the provisions of Section 2.7(a), SpinCo is required to carry back losses or credits, SpinCo shall be entitled to any refund of any Tax obtained

by Parent or a Parent Affiliate as a result of the carryback of losses or credits of SpinCo or a SpinCo Affiliate from any Post-Distribution Tax Period to any Pre-Distribution Tax Period or Straddle Period. Such refund is limited to the net amount received by Parent or a Parent Affiliate (by refund, offset against other Taxes, or otherwise), net of any Tax Detriment incurred by Parent or such Affiliate resulting from such refund. Upon request by SpinCo, Parent shall advise SpinCo of an estimate of any Tax Detriment Parent projects will be associated with any carryback of losses or credits of SpinCo and its Affiliates provided in this Section 2.7(b).

(c) If SpinCo has a Tax Item that must be carried back to any Pre-Distribution Tax Period, SpinCo shall notify in writing Parent that such Tax Item must be carried back. Such notification shall include a description in reasonable detail of the grounds for the refund and the amount thereof, and a certification by an appropriate officer of SpinCo setting forth SpinCo’s belief (together with supporting analysis) that the Tax treatment of such Tax Item is more likely than not correct, and is not a Tax Item arising from a Reportable Transaction.

(d) If Parent pays any amount to SpinCo under Section 2.7(b) and, as a result of a subsequent Final Determination, SpinCo is not entitled to some or all of such amount, Parent shall notify SpinCo of the amount to be repaid to Parent, and SpinCo shall then repay such amount to Parent, together with any interest, fines, additions to Tax, penalties or any other additional amounts imposed by a Taxing Authority relating thereto.

(ii) to the knowledge and belief of Parent, no officer or director of Parent or any Parent Affiliate (nor any person acting with the permission of any such officer or director) has participated in any “agreement, understanding, arrangement or substantial negotiations” (as those terms are used in Treasury Regulations section 1.355-7(h)) with respect to any transaction involving the issuance or other acquisition of SpinCo Capital Stock (excluding for this purpose (x) issuances of SpinCo Capital Stock meeting the requirements of Safe Harbor VIII of Treasury Regulation Section 1.355-7(d) (relating to certain compensatory transfers of stock), (y) transfers on an established market of SpinCo Capital Stock described in Safe Harbor VII of Treasury Regulation Section 1.355-7(d) or (z) issuances of SpinCo Capital Stock described in Safe Harbor IX (relating to acquisitions by a retirement plan of an employer) of Treasury Regulation Section 1.355-7(d)), or any merger or acquisition involving all or substantially all of the assets of SpinCo or a SpinCo Affiliate.

Section 4.2 Covenants.

(a) Each of SpinCo and Parent will not take or fail to take, or permit its Affiliates to take or fail to take, any action where that action or omission would (i) violate, be inconsistent with or cause to be untrue any covenant, representation or statement in the Ruling Documents, any Tax Opinion or a letter or certificate that forms the basis therefor, or (ii) prevent, or be reasonably likely to prevent, the Tax-Free Status.

(b) Neither SpinCo nor any SpinCo Affiliate will, directly or indirectly:

(i) enter into, or otherwise be a party to, any transaction or arrangement (including, without limitation, stock issuances, stock acquisitions, and transactions involving the stock or substantially all of the assets of SpinCo or any SpinCo Affiliate) pursuant to which one or more persons acquire stock of SpinCo or any SpinCo Affiliate representing a “50-percent or greater interest” within the

meaning of Section 355(d)(4) of the Code that would cause Section 355(e) of the Code to apply to the Distribution;

(ii) take or fail to take any other action (including, without limitation, any voluntary cessation or disposition of its Active Trade or Business) that would cause the contribution of property to SpinCo and/or the Distribution to fail to have Tax-Free Status;

(iii) during the Restricted Period, permit any transaction or series of transactions (or any agreement, understanding or arrangement to enter into a transaction or series of transactions) as determined for purposes of Section 355(e) of the Code, in connection with which any person would (directly or indirectly) acquire, or have the right to acquire, from any other person, any interest in SpinCo Capital Stock which, when aggregated with all other such specified transactions undertaken during the Restricted Period, would involve the acquisition (determined under the principles of Section 355(e) of the Code) by one or more persons of more than forty percent (40%) (by vote or by value) of the SpinCo Capital Stock (a “Proposed Acquisition Transaction”). For these purposes, any recapitalization, repurchase or redemption of SpinCo Capital Stock shall be treated as an indirect acquisition of such stock by any non-exchanging shareholder to the extent such shareholder’s percentage interest in SpinCo Capital Stock increases by vote or value. Notwithstanding the foregoing, a Proposed Acquisition Transaction shall not include (w) the adoption by SpinCo of a shareholder rights plan that meets the requirements of IRS Revenue Ruling 90-11, (x) issuances of SpinCo Capital Stock meeting the requirements of Safe Harbor VIII of Treasury Regulation Section 1.355-7(d) (relating to certain compensatory transfers of stock), (y) transfers on an established market of SpinCo Capital Stock described in Safe Harbor VII of Treasury Regulation Section 1.355-7(d) or (z) issuances of SpinCo Capital Stock described in Safe Harbor IX (relating to acquisitions by a retirement plan of an employer) of Treasury Regulation Section 1.355-7(d);

(iv) during the Restricted Period, permit any transaction or series of transactions (or any agreement, understanding or arrangement to enter into a transaction or series of transactions) as determined for purposes of Section 355(e) of the Code, in connection with which any member of the SpinCo Group would merge or consolidate with any person (other than any other member of the SpinCo Group) or transfer its assets to such a person in a transaction described in Section 355(e)(3)(B) of the Code and as a result of which, after taking into account any acquisition of SpinCo Capital Stock required to be taken into account for purposes of clause (iii) above, the stockholders of SpinCo immediately after the Distribution would continue to own, directly or indirectly, less than sixty percent (60%) (by vote or by value) of the capital stock or other ownership interests in the acquiring person; or

(v) during the Restricted Period, liquidate or partially liquidate, including by way of merger or consolidation, SpinCo or any corporation that constitutes a SpinCo Affiliate immediately after the Distribution;

(c) Notwithstanding paragraph (b), clauses (iii) through (v) of paragraph (b) shall not apply upon the prior written consent of Parent, which consent may not be withheld if Parent determines in good faith that SpinCo has provided it with Satisfactory Guidance that the proposed actions will not result in Transaction Taxes. In addition, in the event that SpinCo intends to consummate any Proposed Acquisition Transaction or any transaction described in clause (iv) of paragraph (b) more than one year after the Distribution Date, then SpinCo shall be permitted to consummate such proposed transaction, provided that SpinCo shall provide Parent with an unconditional certification that it did not have any agreement, understanding, arrangement, or substantial negotiations, within the meaning of Treasury Regulations Section 1.355-7(h), with the counterparty to such transaction within 12 months after the Distribution Date, and Parent after reasonable investigation is satisfied with the correctness of such certification.

Section 4.3 Procedures Regarding Opinions and Rulings.

(a) If SpinCo may take certain actions conditioned upon the receipt of Satisfactory Guidance, Parent, at the request of SpinCo, shall use commercially reasonable efforts to obtain expeditiously, or to assist SpinCo in obtaining, such Satisfactory Guidance. Parent shall not be required to take any action pursuant to this Section 4.3(a) if SpinCo fails to certify, upon request, that all information and representations relating to any member of the SpinCo Group in the relevant documents are true, correct and complete. SpinCo shall reimburse Parent for all reasonable out-of-pocket costs and expenses incurred by Parent in obtaining Satisfactory Guidance.

(b) Parent shall have the right to obtain a ruling from the IRS (or any other Taxing Authority) or an Unqualified Tax Opinion at any time in its sole discretion. Parent shall reimburse SpinCo for all reasonable out-of-pocket costs and expenses incurred by the SpinCo Group in obtaining such a ruling or Unqualified Tax Opinion.

ARTICLE V

Tax Contests; Indemnification; Cooperation

Section 5.1 Notice.

(a) Within 15 Business Days after a party (the “Indemnitee”) becomes aware of the existence of a Tax Contest that may give rise to an indemnification claim under this Agreement by it against the other party (the “Indemnifying Party”), the Indemnitee shall promptly notify the Indemnifying Party of the Tax Contest, and thereafter shall promptly forward or make available to the Indemnifying Party copies of notices and communications with a Taxing Authority relating to such Tax Contest.

(b) The Indemnifying Party shall not be responsible for any increase in amounts to which the Indemnitee is otherwise entitled to the extent that such increase results

solely from the failure of the Indemnitee to provide timely notice as required pursuant to Section 5.1(a).

Section 5.2 Control of Tax Contests.

(a) Except as otherwise provided in paragraph (b):

(i) Parent may elect to control, and to have sole discretion in handling, settling or contesting, any Tax Contest relating to any Joint Returns, any Parent Separate Returns, any SpinCo Separate Returns relating to U.S. state and local Income Taxes for taxable periods ending on or before the Distribution Date (i.e., excluding Straddle Periods), or the Tax treatment of the Transactions, provided that (x) Parent shall act in good faith in connection with its control of any such Tax Contests and (y) SpinCo shall have the right to participate in and advise on (including, without limitation, the opportunity to review and comment upon Parent’s communications with the Taxing Authority, which comments shall be incorporated upon the consent of Parent, not to be unreasonably withheld) such items for which SpinCo could be liable under Article II as a result of such Tax Contest; and

(ii) If SpinCo disagrees with Parent’s decision to settle a Tax Contest that may reasonably be expected to affect amounts for which it is liable under Article II, it shall have the right to contest its liability to Parent under Article II notwithstanding the settlement. SpinCo shall provide written notice to Parent of its intention to contest its liability as a result of any settlement (and its irrevocable election described below) prior to the time such settlement is entered into. Any such contest by SpinCo shall be made under the procedures set forth in Article VI. Under those procedures, SpinCo may irrevocably elect, in its sole discretion, to require the Tax Advisor or the arbitrator to determine either (x) the amount of a settlement with the relevant Taxing Authority that would most accurately reflect the litigation risk of the relevant issue, or (y) the most likely outcome of the issue if it were litigated without a settlement. In either such case, SpinCo shall be liable to Parent, or Parent shall be liable to SpinCo, based solely on the determination of the Tax Advisor or the arbitrator as if a settlement or litigation implementing such determination had actually occurred, without regard to the actual settlement. For the avoidance of doubt, this clause (ii) shall not limit Parent’s ability to settle a Tax Contest.

(b) Parent and SpinCo shall jointly control Tax Contests relating to Tax liability arising from the failure of the Distribution to qualify for tax-free treatment under Section 355 of the Code, if SpinCo potentially would be liable to Parent under Article II as a result of such Tax Contest. Neither party shall have the right to settle any such Tax Contest without the consent of the other party.

(c) SpinCo shall have sole control over any Tax Contest relating to the SpinCo Separate Returns (other than U.S. state and local Income Tax Returns for taxable periods

ending on or before the Distribution Date); provided, however, that if Parent is responsible under this Agreement for any Taxes relating to such Tax Contest, then:

(i) SpinCo may elect to control, and to have sole discretion in handling, settling or contesting such Tax Contest, provided that (x) SpinCo shall act in good faith in connection with its control of any such Tax Contest and (y) Parent shall have the right to participate in and advise on (including, without limitation, the opportunity to review and comment upon SpinCo’s communications with the Taxing Authority, which comments shall be incorporated upon the consent of SpinCo, not to be unreasonably withheld) such items for which Parent could be liable under Article II as a result of such Tax Contest; and

(ii) If Parent disagrees with SpinCo’s decision to settle such Tax Contest, it shall have the right to contest its liability to SpinCo under Article II notwithstanding the settlement. Parent shall provide written notice to SpinCo of its intention to contest its liability as a result of any settlement (and its irrevocable election described below) prior to the time such settlement is entered into. Any such contest by Parent shall be made under the procedures set forth in Article VI. Under those procedures, Parent may irrevocably elect, in its sole discretion, to require the Tax Advisor or the arbitrator to determine either (x) the amount of a settlement with the relevant Taxing Authority that would most accurately reflect the litigation risk of the relevant issue, or (y) the most likely outcome of the issue if it were litigated without a settlement. In either such case, Parent shall be liable to SpinCo, or SpinCo shall be liable to Parent, based solely on the determination of the Tax Advisor or the arbitrator as if a settlement or litigation implementing such determination had actually occurred, without regard to the actual settlement. For the avoidance of doubt, this clause (ii) shall not limit SpinCo’s ability to settle a Tax Contest.

(d) Any out-of-pocket expenses incurred in handling, settling or contesting any Tax Contest shall be borne ratably by the parties based on their ultimate liability under this Agreement for the Taxes to which the Tax Contest relates; provided, however, that (x) if SpinCo contests a settlement made by Parent as provided in clause (ii) of paragraph (a), Parent shall bear the costs relating to SpinCo’s contest of such settlement unless Parent substantially prevails in such contest and (y) if Parent contests a settlement made by SpinCo as provided in clause (ii) of paragraph (c), SpinCo shall bear the costs related to Parent’s contest of such settlement unless SpinCo substantially prevails in such contest.

Section 5.3 Indemnification Payments.

(a) An Indemnitee shall be entitled to make a claim for payments pursuant to this Agreement when the Indemnitee determines that it is entitled to such payment and the amount of such payment. The Indemnitee shall provide to the Indemnifying Party notice of such claim within ten (10) days of the date on which it first becomes so entitled to claim such payment, including a description of such claim and a detailed calculation of the amount of the indemnification payment that is claimed; provided, however, that no

delay on the part of the Indemnitee in notifying the Indemnifying Party shall relieve the Indemnifying Party from any obligation hereunder unless (and then solely to the extent) the Indemnifying Party is actually and materially prejudiced thereby. Except as provided in paragraph (b), the Indemnifying Party shall make the claimed payment to the Indemnitee within ten (10) days after receiving such notice, unless the Indemnifying Party reasonably disputes its liability for, or the amount of, such payment.

(b) If the Indemnitee will be obligated to make the payment described in paragraph (a) to a Taxing Authority or other third party (including expenses reimbursable under this Agreement), the Indemnifying Party shall not be obligated to pay the Indemnitee more than five (5) days before the Indemnitee incurs such expense or makes such payment. If the Indemnitee’s claim for payment arises from a payment that the Indemnifying Party will receive from a third party, such as a refund, the Indemnifying Party shall not be obligated to pay the Indemnitee until five (5) days after the Indemnifying Party receives such payment.

(c) In the case of a claim under Article II where no payment will be made to or received from a Taxing Authority, paragraph (b) shall be applied to the payments that would be made to or from a Taxing Authority if the SpinCo Group were treated as a standalone group for all taxable periods.

Section 5.4 Interest. If either party fails to make an indemnification payment required by this Agreement within ten (10) Business Days after receipt of notice and demand for payment under the terms of this Agreement, such party also shall be required to pay interest on the amount of such indemnification payment, accruing from the date of notice and demand for payment (or, if later, accruing from the date on which the payment is due under this Agreement) to, but not including, the date of payment, at (a) prior to the tenth (10^th) Business Day following a final determination or agreement of the parties pursuant to the terms of this Agreement with respect to the amount of the indemnity payment, the Applicable Rate and (b) on or after such tenth (10^th) Business Day, the Applicable Rate plus four percent (4%).

Section 5.5 Treatment of Payments. The amount of all indemnification obligations under this Agreement shall be decreased to take into account the Tax Benefits to the Indemnitee of the deductibility or creditability of any indemnified item and shall be increased where necessary so that, after all the required deductions have been made and Taxes imposed, the Indemnitee receives the net amount it would have been entitled to receive under this Agreement in the absence of such deductions and Taxes. Any payments made to one party by another party pursuant to this Agreement shall be treated by the parties for all Tax purposes as a distribution by, or capital contribution to, SpinCo, as the case may be, made immediately prior to the Distribution, except to the extent otherwise required by a Final Determination.

Section 5.6 Expenses. Except as otherwise provided herein, each party and its Affiliates shall bear their own expenses incurred in connection with the preparation of Tax Returns, Tax Contests, and all other matters under this Agreement.

Section 5.7 Cooperation. Each member of the Parent Group and the SpinCo Group shall cooperate fully with all reasonable requests from the other party in connection with the

preparation and filing of Tax Returns, Tax Contests, and all other matters covered by this Agreement.

(a) Such cooperation shall include:

(i) the retention until the expiration of the applicable statute of limitations, and the provision upon request, of Tax Returns, books, records (including information regarding ownership and Tax basis of property), documentation and other information relating to Tax Returns, including accompanying schedules, related workpapers, and documents relating to rulings or other determinations by Taxing Authorities;

(ii) the execution of any document that may be necessary or reasonably helpful in connection with any Tax Contest, the filing of a Tax Return by a member of the Parent Group or the SpinCo Group, obtaining a tax opinion or private letter ruling, or other matters covered by this Agreement, including certification (provided in such form as may be required by applicable law or reasonably requested and made to the best of a party’s knowledge) of the accuracy and completeness of the information it has supplied;

(iii) the use of the parties’ reasonable best efforts to obtain any documentation that may be necessary or reasonably helpful in connection with any of the foregoing;

(iv) the use of the parties’ reasonable best efforts to make the applicable party’s current or former officers, employees, agents and facilities available on a reasonable and mutually convenient basis in connection with the foregoing matters; and

(v) making determinations with respect to actions described in Section 4.2(c) as promptly as practicable including, without limitation, making determinations within 10 days with respect to modifications and amendments of employee stock purchase agreements or equity compensation plans under Section 4.2(b)(i)(x).

(b) If a party fails to comply with any of its obligations set forth in this Section 5.7 upon reasonable request and notice by the other party, and such failure results in the imposition of additional Taxes, the nonperforming party shall be liable in full for such additional Taxes.

Section 5.8 Confidentiality. Any information or documents provided under this Agreement shall be kept confidential by the recipient, except as may otherwise be necessary in connection with the filing of Tax Returns or with any Tax Contest. In addition, if Parent or SpinCo determines that providing such information could be commercially detrimental, violate any law or agreement or waive any privilege, the parties shall use reasonable best efforts to permit compliance with the obligations under this Agreement in a manner that avoids any such harm or consequence.

Section 5.9 Retention of Tax Records. SpinCo may request from Parent and retain copies of (i) with respect to any Joint Return, all pro forma federal and state Tax Returns, supporting schedules and workpapers related to members of the SpinCo Group, and (ii) any Separate Returns for any SpinCo Group members, including supporting schedules and workpapers. If either Parent or SpinCo intends to dispose of documentation with respect to any Pre-Distribution Tax Period, including books, records, Tax Returns and all supporting schedules and information relating thereto (after the expiration of the applicable statute of limitations), of any member of the other Group, or in the case of the SpinCo Group any member included in a Joint Return, they shall provide written notice to the other party describing the documentation to be disposed of 30 days prior to taking such action. The other party may arrange to take delivery of the documentation described in the notice at its own expense during the succeeding 30 day period.

ARTICLE VI

Resolution of Disputes

Any controversy, dispute or claim arising out of, in connection with, or in relation to the interpretation, performance, nonperformance, validity or breach of this Agreement or otherwise arising out of, or in any way related to this Agreement shall be resolved under dispute resolution procedures similar to those contained in Article V of the Distribution Agreement; provided, however, that if the dispute is to be referred to non-binding mediation under such procedures, a mediator who qualifies as a Tax Advisor shall be selected, or the parties shall select a Tax Advisor in lieu of selecting a mediator.
