For all purposes of this Agreement, a Tax and any Tax Items shall be considered attributable to the Everett Business on the one hand and the Houston Business on the other (but not both) to the extent that such Tax and/or Tax Item would result if such Tax Return were prepared on a separate basis taking into account only the operations and assets of the Everett Business on the one hand and only the operations and assets of the Houston Business on the other hand (but not both), as applicable.

The other Company shall have access to any and all data and information necessary for the preparation of all such Tax Returns and the Companies shall cooperate fully in the preparation and review of such Tax Returns. Subject to the preceding sentence, no later than fifteen (15) days after receipt of such Tax Returns (reduced to ten (10) days for state or local Tax Returns), the other Company shall have a right to object to such Tax Return (or items with respect thereto) by written notice to the Responsible Company; such written notice shall contain such disputed item (or items) and the basis for its objection. For purposes of this Section 3.05(a), a Tax Return is “material” with respect to a Company who is not the Responsible Company if it could reasonably be expected to reflect, with respect to such Company, (A) Tax liability equal to or in excess of Ten Million Dollars ($10,000,000), (B) a credit or credits equal to or in excess of Ten Million Dollars ($10,000,000), (C) a loss or losses equal to or in excess of Ten Million Dollars ($10,000,000) or (D) could otherwise be expected to materially adversely affect a Tax position with respect to the Company or its Group.

(b) If a Company does object by proper written notice described in Section 3.05(a), the Companies shall act in good faith to resolve any such dispute as promptly as practicable; provided, however, that, notwithstanding anything to the contrary contained herein, if the Companies have not resolved the disputed item or items by the day five (5) days prior to the Due Date of such Tax Return, such Tax Return shall be filed as prepared pursuant to this Section 3.05 (revised to reflect all initially disputed items that the Companies have agreed upon prior to such date).

(c) In the event a Tax Return is filed that includes any disputed item for which proper notice was given pursuant to Section 3.05(a) that was not finally resolved and agreed upon, such disputed item (or items) shall be resolved in accordance with Section 14. In the event that the resolution of such disputed item (or items) in accordance with Section 14 with respect to a Tax Return is inconsistent with such Tax Return as filed, the Responsible Company (with cooperation from the other Company) shall, as promptly as practicable, amend such Tax Return to properly reflect the final resolution of the disputed item (or items). In the event that the amount of Taxes shown to be due and owing on a Tax Return is adjusted as a result of a resolution pursuant to Section 14, proper adjustment shall be made to the amounts previously paid or required to be paid in accordance with Section 4 in a manner that reflects such resolution.

17

Refunds, Carrybacks and Amended Tax Returns.

(a) Refunds.

(i) Each Company (and its Affiliates) (the “Claiming Company”) shall be entitled to Refunds that relate to Taxes for which it (or its Affiliates) is liable hereunder. For the avoidance of doubt, to the extent that a particular Refund of Taxes may be allocable to a Straddle Period with respect to which the Parties may share responsibility pursuant to Sections 2 and 3, the portion of such Refund to which each Party will be entitled shall be determined by comparing the amount of payments made by a Party to a Tax Authority or to the other Party (and reduced by the amount of payments received from the other Party) pursuant to Sections 2 and 3 with the Tax liability of such Party as determined under Section 2.03, taking into account the facts as utilized for purposes of claiming such Refund.

(ii) Notwithstanding Section 3.06(a)(i), to the extent a claim for a Refund results in a Correlative Detriment to the other Company (or its Affiliates), any such Refund that is received by the Claiming Company (or its Affiliates) shall, and only to the extent thereof, be paid to the other Company (or its Affiliates) that incurs such Correlative Detriment. A “Correlative Detriment” is an increase in a Tax of a Company (or its Affiliates) that occurs as a result of the Tax position that is the basis for a claim for Refund by the Claiming Company or for a Final Determination, utilizing the assumptions set forth in the description of Houston Full Taxpayer or Everett Full Taxpayer, as the case may be.

(iii) In the event of an adjustment relating to Taxes pursuant to a Final Determination for which one Party is responsible under this Agreement which would have given rise to a Refund but for an offset against the Taxes for which the other Party is or may be responsible pursuant to this Agreement (the “Benefited Party”), then the Benefited Party shall pay to the other Party, within ten (10) days of the Final Determination of such adjustment an amount equal to the amount of such reduction in the Taxes of the Benefited Party plus interest at the Prime Rate on such amount for the period from the filing date of the Tax Return that would have given rise to such Refund to the payment date.

18

(iv) Any Refund or portion thereof to which a Claiming Company is entitled pursuant to this Section 3.06(a) that is received or deemed to have been received as described herein by the other Company (or its Affiliates) shall be paid by such other Company to the Claiming Company in immediately available funds in accordance with Section 4. To the extent a Company (or its Affiliates) applies or causes to be applied an overpayment of Taxes as a credit toward or a reduction in Taxes otherwise payable (or a Tax Authority requires such application in lieu of a Refund) and such Refund, if received, would have been payable by such Company to the Claiming Company pursuant to this Section 3.06(a), such Company shall be deemed to have actually received a Refund to the extent thereof on the date on which the overpayment is applied to reduce Taxes otherwise payable.

(v) Notwithstanding anything to the contrary in this Agreement, any Company that has claimed (or caused one or more of its Affiliates to claim) a Refund shall be liable for any Taxes that become due and payable as a result of the subsequent adjustment, if any, to the Refund claim.

(b) Carrybacks.

(i) Each of the Companies shall be permitted (but not required) to carry back (or to cause its Affiliates to carry back) a Tax Attribute realized in a Post-Distribution Period or a Straddle Period to a Pre-Distribution Period or a Straddle Period only if such carryback cannot reasonably result in the other Company (or its Affiliates) being liable for additional Taxes. If a carryback could reasonably result in the other Company (or its Affiliates) being liable for additional Taxes, such carryback shall be permitted only if such Company consents to such carryback.

(ii) Notwithstanding anything to the contrary in this Agreement, any Company that has claimed (or caused one or more of its Affiliates to claim) a Tax Attribute carryback shall be liable for any Taxes that result from such carryback claim or become due and payable as a result of the subsequent adjustment, if any, to the carryback claim.

(iii) A Company shall be entitled to any Refund that is attributable to, and would not have arisen but for, a carryback of a Tax Attribute by such Company pursuant to the provisions set forth in Section 3.06(b).

(iv) A Company shall be entitled to any Tax Benefit actually recognized by the other Company or its Affiliates as a result of any carryback of a Tax Attribute by such first Company.

(c) Amended Tax Returns.

(i) Notwithstanding Section 3.01, a Company (or its Affiliates) that is entitled to file an amended Tax Return for a Pre-Distribution Period or a Straddle Period shall be permitted to prepare and file such amended Tax Return at its own cost and expense; provided, however, that such amended Tax Return shall be prepared

19

in a manner (i) consistent with the past practice of the Companies (and their Affiliates) unless otherwise modified by a Final Determination or required by applicable Tax Law; and (ii) consistent with (and the Companies and their Affiliates shall not take any position inconsistent with) the Tax Opinions/Rulings. Notwithstanding anything to the contrary contained herein, if such amended Tax Return could reasonably result in the other Company becoming responsible for a payment of (or otherwise becoming liable for) Taxes under this Agreement, then such amended Tax Return shall be permitted only if the consent of such other Company is obtained. The consent of such other Company shall be deemed to be obtained in the event that a Company (or its Affiliate) is required by Law to file an amended Tax Return as a result of an adjustment.

(ii) A Company (or its Affiliate) that is entitled to file an amended Tax Return for a Post-Distribution Period shall be permitted to do so without the consent of the other Company.

(iii) A Company that is permitted (or whose Affiliate is permitted) to file an amended Tax Return shall not be relieved of any liability for payments pursuant to this Agreement notwithstanding that the Company consented to the filing of such amended Tax Return giving rise to such liability.

Apportionment of Tax Attributes. Houston shall reasonably determine in good faith, and advise Everett in writing, of the amount of any Tax Attributes arising in a Pre-Distribution Period that shall be allocated or apportioned to Everett and/or the Everett Group under applicable Law, provided that this Section 3.07 shall not be construed as obligating Houston to undertake an “earnings & profits study” or similar determination. Houston shall consult in good faith with Everett regarding such determinations. In the event that Everett disagrees with any such determination, Houston and Everett shall endeavor in good faith to resolve such disagreement, and, failing that, the allocations and apportionments under this Section 3.07 shall be determined in accordance with the disagreement resolution provisions of Section 14 as promptly as practicable. The Houston Group and the Everett Group agree to compute all Taxes for Post-Distribution Periods consistently with the determination of the allocation of Tax Attributes pursuant to this Section 3.07 unless otherwise required by a Final Determination. To the extent that the amount of any Tax Attribute is later reduced or increased as a result of a Final Determination, such reduction or increase shall be allocated to the Party to which such Tax Attribute was allocated pursuant to this Section 3.07.

Tax Payments.

Payment of Taxes.

(a) Computation and Payment of Tax Due. At least three (3) Business Days prior to any Payment Date for any Tax Return, the Responsible Company shall compute the amount of Tax required to be paid to the applicable Tax Authority (taking into account the requirements of Section 3.03 relating to consistent reporting practices, as applicable) with respect to such Tax Return on such Payment Date. The Responsible Company shall pay such amount to such Tax Authority on or before such Payment Date. The Responsible Company shall provide notice to the other Company setting forth such other Company’s responsibility for the amount of Taxes paid to the Tax Authority and provide proof of payment of such Taxes.

20

(b) Computation and Payment of Liability with Respect to Tax Due. Within thirty (30) Business Days following the earlier of (i) the due date (including extensions) for filing any such Tax Return (excluding any Tax Return with respect to payment of estimated Taxes or Taxes due with a request for extension of time to file) or (ii) the date on which such Tax Return is filed, if Houston is the Responsible Company, then Everett shall pay to Houston the amount allocable to the Everett Group under the provisions of this Agreement, and if Everett is the Responsible Company, then Houston shall pay to Everett the amount allocable to the Houston Group under the provisions of this Agreement, in each case, plus interest computed at the Prime Rate on the amount of the payment based on the number of days from the earlier of (i) the due date of the Tax Return (including extensions) or (ii) the date on which such Tax Return is filed, to the date of payment. For the avoidance of doubt, however, the thirty (30) Business Day period described herein shall not commence unless and until the Responsible Company notifies the other Company pursuant to Section 4.01(a) hereof, nor shall interest accrue during any time period where such notification has not been received.

(c) Adjustments Resulting in Underpayments. In the case of any adjustment pursuant to a Final Determination with respect to any such Tax Return, the Responsible Company shall pay to the applicable Tax Authority when due any additional Tax due with respect to such Tax Return required to be paid as a result of such adjustment pursuant to such Final Determination. The Responsible Company shall compute the amount attributable to the Everett Group or the Houston Group (as the case may be) in accordance with this Agreement and Everett shall pay to Houston any amount due Houston (or Houston shall pay Everett any amount due Everett) under this Agreement within thirty (30) Business Days from the later of (i) the date the additional Tax was paid by the Responsible Company or, in an instance where no cash payment is due to a Tax Authority, the date of such Final Determination, or (ii) the date of receipt of a written notice and demand from the Responsible Company for payment of the amount due, accompanied by evidence of payment and a statement detailing the Taxes paid and describing in reasonable detail the particulars relating thereto. Any payments required under this Section 4.01(c) shall include interest computed at the Prime Rate based on the number of days from the date the additional Tax was paid by the Responsible Company (or, in an instance where no cash payment is due to a Tax Authority, the date of such Final Determination) to the date of the payment under this Section 4.01(c).

Indemnification Payments.

(a) If any Company (the “Payor”) is required under applicable Tax Law to pay to a Tax Authority a Tax that another Company (the “Required Company”) is liable for under this Agreement, the Payor shall provide notice to the Required Company for the amount due, accompanied by evidence of payment and a statement detailing the Taxes paid and describing in reasonable detail the particulars relating thereto. Such Required Company shall have a period of thirty (30) days after the receipt of notice to respond thereto. Unless the Required Company disputes the amount it is liable for under this Agreement, the Required Company shall reimburse the Payor within forty-five (45) Business Days of delivery by the Payor of the notice described above. To the extent the Required Company does not agree with the amount the Payor claims the Required Company is liable for under this Agreement, the dispute shall be resolved in

21

accordance with Section 14. Any reimbursement shall include interest on the Tax payment computed at the Prime Rate based on the number of days from the date of the payment to the Tax Authority to the date of reimbursement under this Section 4.02.

(b) Any Tax indemnity payment required to be made by the Required Company pursuant to this Agreement shall be reduced by any corresponding Tax Benefit payment required to be made to the Required Company by the other Company pursuant to Section 5. For the avoidance of doubt, a Tax Benefit payment is treated as corresponding to a Tax indemnity payment to the extent the Tax Benefit realized is directly attributable to the same Tax Item (or adjustment of such Tax Item pursuant to a Final Determination) that gave rise to the Tax indemnity payment.

(c) All indemnification payments under this Agreement shall be made by Houston directly to Everett and by Everett directly to Houston; provided, however, that if the Companies mutually agree with respect to any such indemnification payment, any member of the Houston Group, on the one hand, may make such indemnification payment to any member of the Everett Group, on the other hand, and vice versa. All indemnification payments shall be treated in the manner described in Section 13.

Tax Benefits and Houston Tax Attributes.

Tax Benefits.

(a) If a member of the Everett Group recognizes any Tax Benefit as a result of an adjustment pursuant to a Final Determination to any Taxes for which a member of the Houston Group is liable hereunder and such Tax Benefit would not have arisen but for such adjustment (determined on a “with and without” basis), or if a member of the Houston Group recognizes any Tax Benefit as a result of an adjustment pursuant to a Final Determination to any Taxes for which a member of the Everett Group is liable hereunder and such Tax Benefit would not have arisen but for such adjustment (determined on a “with and without” basis), Everett or Houston, as the case may be, shall make a payment to the other company within one hundred twenty (120) Business Days following such actual recognition of the Tax Benefit, in an amount equal to such Tax Benefit, plus interest on such amount computed at the Prime Rate based on the number of days from the date of such actual realization of the Tax Benefit to the date of payment of such amount under this Section 5.01(a).

(b) No later than one hundred twenty (120) Business Days after a Tax Benefit described in Section 5.01(a) is actually recognized by a member of the Houston Group or a member of the Everett Group, Houston (if a member of the Houston Group recognizes such Tax Benefit) or Everett (if a member of the Everett Group recognizes such Tax Benefit) shall provide the other Company with notice of the amount payable to such other Company by Houston or Everett pursuant to this Section 5. In the event that Houston or Everett disagrees with any such calculation described in this Section 5.01(b), Houston or Everett shall so notify the other Company in writing within thirty (30) Business Days of receiving the written calculation set forth above in this Section 5.01(b). Houston and Everett shall endeavor in good faith to resolve such disagreement, and, failing that, the amount payable under this Section 5 shall be determined in accordance with the disagreement resolution provisions of Section 14 as promptly as practicable.

(c) For the avoidance of doubt, this Section 5 shall apply to any adjustment under Section 482 of the Code or any similar provisions by any Tax Authority increasing the amount of payments received or deemed received by (1) any member of the Houston Group from any member of the Everett Group (excluding Chicago and its Affiliates) or (2) any member of the Everett Group (excluding Chicago and its Affiliates) from any member of the Houston Group.

22

Houston UK Tax NOLs Utilization Payments.

(a) Everett shall pay to Houston the amount, if any, of the Five-Year Houston UK Tax NOLs Utilization Amount Payment within one hundred twenty (120) Business Days following the close of the fifth (5th) full taxable year for United Kingdom Income Tax purposes following the Distribution Date.

(b) Everett shall pay to Houston the amount, if any, of the 10-Year Houston UK Tax NOLs Utilization Amount Payment within one hundred twenty (120) Business Days following the close of the tenth (10th) full taxable year for United Kingdom Income Tax purposes following the Distribution Date.

(c) All calculations relating to the payments, if any, to be made under this Section 5.02 shall be determined by Everett in good faith and with reasonable consultation with Houston. Any disputes relating to payments, if any, to be made under this Section 5.02 shall be resolved in accordance with Section 14.

Employee Benefits Matters.

Houston and Everett Income Tax Deductions in Respect of Certain Equity Awards and Compensation. Unless otherwise required by applicable Law, solely the member of the Group for which the relevant individual is currently employed or, if such individual is not currently employed by a member of the Group, was most recently employed at the time of the vesting, exercise, disqualifying disposition, payment or other relevant taxable event, as appropriate, in respect of equity awards and other compensation shall be entitled to claim any Income Tax deduction in respect of such equity awards and other compensation on its respective Tax Return associated with such event.

Withholding and Reporting. The Company (or its Affiliate) that claims the deduction described in Section 6.01 shall be responsible for all applicable Taxes (including withholding and excise taxes) and shall satisfy, or shall cause to be satisfied, all applicable Tax reporting obligations in respect of compensation that gives rise to the deduction. The Companies shall cooperate (and shall cause their Affiliates to cooperate) so as to permit the Company (or Affiliate thereof) claiming such deduction described in Section 6.01 to discharge any applicable Tax withholding and Tax reporting obligations, including the appointment of a Company (or its Affiliate) claiming the deduction as the withholding and reporting agent if that Company (or any of its Affiliates) is not otherwise required or permitted to withhold or report under applicable Law.

Pension Deductions. In the event that Everett actually recognizes a Tax Benefit in a Post-Distribution Tax Period arising from contributions made to the EDS Pension Plan with respect to which a payment by Houston to HP Inc. is required pursuant to Section 6.03 of the Tax Matters Agreement entered into by and between Houston and Hewlett-Packard Company on

23

October 31, 2015 and the addendums thereto, as amended through the date hereof, Everett shall make a payment to Houston of the amount of such actually recognized Tax Benefit within 30 Business Days.

Tax-Free Status.

Restrictions on Everett. During the Restricted Period, Everett and Chicago shall not:

(a) enter into any Proposed Acquisition Transaction, approve any Proposed Acquisition Transaction for any purpose, or allow any Proposed Acquisition Transaction to occur with respect to Everett;

(b) merge or consolidate with any other Person (other than pursuant to the Merger) or liquidate or partially liquidate; or approve or allow any merger, consolidation, liquidation, or partial liquidation of any of the Active Business Entities;

(c) approve or allow the discontinuance, cessation, or sale or other transfer (to an Affiliate or otherwise) of, or a material change in, any Active Business;

(d) approve or allow the sale, issuance, or other disposition (to an Affiliate or otherwise), directly or indirectly, of any share of, or other equity interest or an instrument convertible into an equity interest in, any of the Active Business Entities;

(e) sell or otherwise dispose of more than thirty-five percent (35%) percent of its consolidated gross or net assets, or approve or allow the sale or other disposition (to an Affiliate or otherwise) of more than thirty-five percent (35%) of its consolidated gross or net assets or more than thirty-five percent (35%) of the consolidated gross or net assets of any of the Active Business Entities (in each case, excluding (A) sales in the ordinary course of business and measured based on fair market values as of the Distribution Date, (B) sales or other dispositions relating to the business(es) set forth on Schedule 1 or (C) any transfers to a Person that is a disregarded entity separate from the transferor for federal income tax purposes;

(f) amend its certificate of incorporation (or other organizational documents), or take any other action or approve or allow the taking of any action, whether through a stockholder vote or otherwise, affecting the voting rights of Everett stock;

(g) issue shares of a new class of non-voting stock;

(h) purchase, directly or through any Affiliate, any of its outstanding stock, other than through stock purchases meeting the requirements of Section 4.05(1)(b) of Revenue Procedure 96-30 (without regard to the effect of Revenue Procedure 2003-48 on Revenue Procedure 96-30);

(i) with respect to the Distribution, other than with respect to the business(es) set forth on Schedule 1, take any action or fail to take any action, or permit any member of the Everett Group to take any action or fail to take any action, that is inconsistent with any representation or covenant made in the Tax Opinions/Rulings or the Ruling Request; or

(j) other than with respect to the business(es) set forth on Schedule 1, take any action or permit any other member of the Everett Group to take any action (including any transactions with a third-party or any transaction with any Company) that, individually or in the aggregate (taking into account other transactions described in this Section 7.01) would be reasonably likely to adversely affect (A) the Tax-Free Status of the Contribution and Distribution, or (B) any Separation Transaction to qualify for its intended treatment as set forth in the Tax Opinions/Rulings (limited, in the case of those Separation Transactions intended to qualify for such treatment under foreign Law, to the extent set forth on Schedule 2);

24

provided, however, that Everett or Chicago shall be permitted to take such action or one or more actions set forth in the foregoing clauses (a) through (j) if, prior to taking any such actions, Everett or Chicago shall (1) have received a favorable private letter ruling from the IRS, or a ruling from another Tax Authority that confirms that such action or actions will not result in Distribution Taxes, taking into account such actions and any other relevant transactions in the aggregate (a “Post-Distribution Ruling”), in form and substance satisfactory to Houston in its discretion, which discretion shall be reasonably exercised in good faith to prevent the imposition on Houston, or responsibility for payment by Houston, of Distribution Taxes (which discretion shall include consideration of the reasonableness of any representations made in connection with such Post-Distribution Ruling) or (2) have received an Unqualified Tax Opinion that confirms that such action or actions will not result in Distribution Taxes, taking into account such actions and any other relevant transactions in the aggregate, in form and substance satisfactory to Houston (including any representations or assumptions that may be included in such Unqualified Tax Opinion), acting reasonably and in good faith solely to prevent the imposition on Houston, or responsibility for payment by Houston, of Distribution Taxes. Everett and Chicago shall provide a copy of the Post-Distribution Ruling or the Unqualified Tax Opinion described in this paragraph to Houston as soon as practicable prior to taking or failing to take any action set forth in the foregoing clause (a) through (j). Houston’s evaluation of a Post-Distribution Ruling or Unqualified Tax Opinion may consider, among other factors, the appropriateness of any underlying assumptions, representations, and covenants made in connection with such Post-Distribution Ruling or Unqualified Tax Opinion. Everett shall bear all costs and expenses of securing any such Post-Distribution Ruling or Unqualified Tax Opinion and shall reimburse Houston for all reasonable out-of-pocket costs and expenses that Houston may incur in good faith in seeking to obtain or evaluate any such Post-Distribution Ruling or Unqualified Tax Opinion.

Liability for Distribution Tax-Related Losses. In the event that Distribution Taxes become due and payable to a Tax Authority pursuant to a Final Determination, then, notwithstanding anything to the contrary in this Agreement:

(a) if such Distribution Taxes are attributable to a Houston Tainting Act, then Houston shall be responsible for any Distribution Tax-Related Losses;

(b) if such Distribution Taxes are attributable to an Everett Tainting Act, then Everett shall be responsible for any Distribution Tax-Related Losses; and

(c) if such Distribution Taxes are not attributable to a Houston Tainting Act or an Everett Tainting Act, then Houston shall be one hundred percent (100%) responsible for such Distribution Tax-Related Losses.

25

Cooperation and Reliance.

Assistance and Cooperation.

(a) The Companies shall cooperate (and cause their respective Affiliates to cooperate) with each other and with each other’s agents, including accounting firms and legal counsel, in connection with Tax matters relating to the Companies and their Affiliates including (i) preparation and filing of Tax Returns, (ii) determining the liability for and amount of any Taxes due (including estimated Taxes) or the right to and amount of any refund of Taxes, (iii) examinations of Tax Returns, and (iv) any administrative or judicial proceeding in respect of Taxes assessed or proposed to be assessed. Such cooperation shall include making all information and documents in their possession relating to the other Company and its Affiliates available to such other Company as provided in Section 9. Each of the Companies shall also make available to the other, as reasonably requested and available, personnel (including officers, directors, employees and agents of the Companies or their respective Affiliates) responsible for preparing, maintaining, and interpreting information and documents relevant to Taxes, and personnel reasonably required as witnesses or for purposes of providing information or documents in connection with any administrative or judicial proceedings relating to Taxes. In the event that a member of the Houston Group, on the one hand, or a member of the Everett Group, on the other hand, suffers a Tax detriment as a result of a Transfer Pricing Adjustment, the Companies shall cooperate pursuant to this Section 8 to seek any competent authority relief that may be available with respect to such Transfer Pricing Adjustment.

(b) Any information or documents provided under this Section 8 shall be kept confidential by the Company receiving the information or documents, except as may otherwise be necessary in connection with the filing of Tax Returns or in connection with any administrative or judicial proceedings relating to Taxes. Notwithstanding any other provision of this Agreement or any other agreement, (i) neither Company nor any Affiliate shall be required to provide the other Company or any Affiliate or any other Person access to or copies of any information or procedures (including the proceedings of any Tax Contest) other than information or procedures that relate solely to the first Company, the business or assets of the first Company or any of its Affiliates and (ii) in no event shall any Company or its Affiliates be required to provide the other Company, any of the other Company’s Affiliates or any other Person access to or copies of any information if such action could reasonably be expected to result in the waiver of any Privilege. In addition, in the event that a Company determines that the provision of any information to the other Company or an Affiliate of the other Company could be commercially detrimental, violate any Law or agreement or waive any Privilege, the Company shall use reasonable best efforts to permit compliance with its obligations under this Section 8 in a manner that avoids any such harm or consequence.

Income Tax Return Information. Everett and Houston acknowledge that time is of the essence in relation to any request for information, assistance or cooperation made by Houston or Everett pursuant to Section 8.01 or this Section 8.02. Each Company shall provide to the other Company information

26

and documents relating to its Group required by the other Company to prepare Tax Returns. Any information or documents the Responsible Company requires to prepare such Tax Returns shall be provided in such form as the Responsible Company reasonably requests and in sufficient time for the Responsible Company to file such Tax Returns on a timely basis.

Non-Performance. If a Company (or any of its Affiliates) fails to comply with any of its obligations set forth in this Section 8 upon reasonable request and notice by the other Company (or any of its Affiliates) and such failure results in the imposition of additional Taxes, the non-performing Company shall be liable in full for such additional Taxes.

Costs. Each Company shall devote the personnel and resources necessary in order to carry out this Section 8 and shall make its employees available on a mutually convenient basis to provide explanations of any documents or information provided hereunder. Each Company shall carry out its responsibilities under this Section 8 at its own cost and expense.

Tax Records.

Retention of Tax Records. Each Company shall preserve and keep all Tax Records exclusively relating to the assets and activities of its Group for Pre-Distribution Periods, and Houston shall preserve and keep all other Tax Records relating to Taxes of the Groups for Pre-Distribution Periods, for so long as the contents thereof may become material in the administration of any matter under the Code or other applicable Tax Law, but in any event until the later of (i) the expiration of any applicable statutes of limitations, or (ii) seven (7) years after the Distribution Date (such later date, the “Retention Date”). After the Retention Date, each Company may dispose of such Tax Records upon ninety (90) Business Days’ prior written notice to the other Company. If, prior to the Retention Date, (a) a Company reasonably determines that any Tax Records which it would otherwise be required to preserve and keep under this Section 9 are no longer material in the administration of any matter under the Code or other applicable Tax Law and the other Company agrees, then such first Company may dispose of such Tax Records upon ninety (90) Business Days’ prior notice to the other Company. Any notice of an intent to dispose given pursuant to this Section 9.01 shall include a list of the Tax Records to be disposed of describing in reasonable detail each file, book, or other record accumulation being disposed. The notified Company shall have the opportunity, at its cost and expense, to copy or remove, within such ninety (90)-day period, all or any part of such Tax Records. If, at any time prior to the Retention Date, a Company determines to decommission or otherwise discontinue any computer program or information technology system used to access or store any Tax Records, then such Company may decommission or discontinue such program or system upon ninety (90) Business Days’ prior notice to the other Company and the other Company shall have the opportunity, at its cost and expense, to copy, within such ninety (90)-day period, all or any part of the underlying data relating to the Tax Records accessed by or stored on such program or system.

Access to Tax Records. The Companies and their respective Affiliates shall make available to each other for inspection and copying during normal business hours upon reasonable notice all Tax Records (and, for the avoidance of doubt, any pertinent underlying data accessed or stored on any computer program or information technology system) in their possession and shall permit the other Company and its Affiliates, authorized agents and representatives and any representative of a Tax Authority or other Tax auditor direct access during normal business hours

27

upon reasonable notice to any computer program or information technology system used to access or store any Tax Records, in each case to the extent reasonably required by the other Company in connection with the preparation of Tax Returns or financial accounting statements, audits, litigation, or the resolution of items under this Agreement. To the extent any Tax Records are required to be or are otherwise transferred by the Companies or their respective Affiliates to any person other than an Affiliate, the Company or its respective Affiliate shall transfer such records to the other Company at such time.

Tax Contests.

Notice. Each of the Companies shall provide prompt notice to the other Company of any written communication from a Tax Authority regarding any pending or threatened Tax audit, assessment or proceeding or other Tax Contest of which it becomes aware related to Taxes for which it is indemnified by the other Company hereunder. Such notice shall attach copies of the pertinent portion of any written communication from a Tax Authority and contain factual information (to the extent known) describing any asserted Tax liability in reasonable detail and shall be accompanied by copies of any notice and other documents received from any Tax Authority in respect of any such matters. If an indemnified Company has knowledge of an asserted Tax liability with respect to a matter for which it is entitled to indemnification hereunder and such Company fails to give the indemnifying Company prompt notice of such asserted Tax liability and the indemnifying Company is entitled under this Agreement to contest the asserted Tax liability, then (i) if the indemnifying Company is precluded from contesting the asserted Tax liability in any forum as a result of the failure to give prompt notice, the indemnifying Company shall have no obligation to indemnify the indemnified Company for such Tax liability or any other Taxes arising from such failure, and (ii) if the indemnifying Company is not precluded from contesting the asserted Tax liability in any forum, but such failure to give prompt notice results in a material monetary detriment to the indemnifying Company, then any amount which the indemnifying Company is otherwise required to pay the indemnified Company pursuant to this Agreement shall be reduced by the amount of such detriment.

Control of Tax Contests.

(a) Controlling Company. In the case of any Tax Contest with respect to any Tax Return, the Company that would be primarily liable under this Agreement to pay the applicable Tax Authority the Taxes resulting from such Tax Contest shall administer and control such Tax Contest.

(b) Settlement Rights. The Controlling Company must obtain the prior consent of the Non-Controlling Company prior to contesting, litigating, compromising or settling any Tax Contest related to an adjustment which the Non-Controlling Company may reasonably be expected to become liable to make any indemnification payment under this Agreement (or any payment under Section 5). Unless waived by the Companies in writing, in connection with any potential adjustment in a Tax Contest as a result of which adjustment the Non-Controlling Company may reasonably be expected to become liable to make any indemnification payment under this Agreement (or any payment under Section 5) to the Controlling Company under this Agreement: (i) the Controlling Company shall keep the Non-Controlling Company informed in a timely manner of all actions taken or proposed to be taken by the Controlling Company with respect to such

28

potential adjustment in such Tax Contest; (ii) the Controlling Company shall provide the Non-Controlling Company copies of any written materials relating to such potential adjustment in such Tax Contest received from any Tax Authority; (iii) the Controlling Company shall timely provide the Non-Controlling Company with copies of any correspondence or filings submitted to any Tax Authority or judicial authority in connection with such potential adjustment in such Tax Contest; (iv) the Controlling Company shall consult with the Non-Controlling Company (including, without limitation, regarding the use of outside advisors to assist with the Tax Contest) and offer the Non-Controlling Company a reasonable opportunity to comment before submitting any written materials prepared or furnished in connection with such potential adjustment in such Tax Contest; and (v) the Controlling Company shall defend such Tax Contest diligently and in good faith. The failure of the Controlling Company to take any action specified in the preceding sentence with respect to the Non-Controlling Company shall not relieve the Non-Controlling Company of any liability and/or obligation which it may have to the Controlling Company under this Agreement except to the extent that the Non-Controlling Company was actually harmed by such failure, and in no event shall such failure relieve the Non-Controlling Company from any other liability or obligation which it may have to the Controlling Company. In the case of any Tax Contest described in Section 10.02(a) or (b), “Controlling Company” means the Company entitled to control the Tax Contest under such Section and “Non-Controlling Company” means the other Company.

(c) Tax Contest Participation. Unless waived by the Companies in writing, the Controlling Company shall provide the Non-Controlling Company with written notice reasonably in advance of, and the Non-Controlling Company shall have the right to attend, any formally scheduled meetings with Tax Authorities or hearings or proceedings before any judicial authorities in connection with any potential adjustment in a Tax Contest pursuant to which the Non-Controlling Company may reasonably be expected to become liable to make any indemnification payment (or any payment under Section 5) to the Controlling Company under this Agreement. The failure of the Controlling Company to provide any notice specified in this Section 10.02(c) to the Non-Controlling Company shall not relieve the Non-Controlling Company of any liability and/or obligation which it may have to the Controlling Company under this Agreement except to the extent that the Non-Controlling Company was actually harmed by such failure, and in no event shall such failure relieve the Non-Controlling Company from any other liability or obligation which it may have to the Controlling Company.

(d) Power of Attorney. Each member of the Everett Group shall execute and deliver to Houston (or such member of the Houston Group as Houston shall designate) any power of attorney or other similar document reasonably requested by Houston (or such designee) in connection with any Tax Contest (as to which Houston is the Controlling Company) described in this Section 10. Each member of the Houston Group shall execute and deliver to Everett (or such member of the Everett Group as Everett shall designate) any power of attorney or other similar document requested by Everett (or such designee) in connection with any Tax Contest (as to which Everett is the Controlling Company) described in this Section 10.

(e) Costs. All external out-of-pocket costs and expenses that are incurred by the Controlling Company with respect to a Tax Contest related to an adjustment which the Non-Controlling Company may reasonably be expected to become liable to make any indemnification payment under this Agreement shall be shared by the Companies according to each Company’s

29

relative share of the potential Tax liability with respect to the Tax Contest as determined under this Agreement; provided, however, that a Non-Controlling Company shall not be liable for fees payable to outside advisors to the extent that the Controlling Company failed to consult with the Non-Controlling Company pursuant to Section 10.02(b). If the Controlling Company incurs out-of-pocket costs and expenses to be shared under this Section 10.02(e) during a fiscal quarter, such Controlling Company shall provide notice to the Non-Controlling Company within thirty (30) days after the end of such fiscal quarter for the amount due from such Non-Controlling Company pursuant to this Section 10.02(e), describing in reasonable detail the particulars relating thereto. Such Non-Controlling Company shall have a period of thirty (30) days after the receipt of notice to respond thereto. Unless the Non-Controlling Company disputes the amount it is liable for under this Section 10.02(e), the Non-Controlling Company shall reimburse the Controlling Company within forty-five (45) Business Days of delivery by the Controlling Company of the notice described above. To the extent the Non-Controlling Company does not agree with the amount the Controlling Company claims the Non-Controlling Company is liable for under this Section 10.02(e), the dispute shall be resolved in accordance with Section 14. Any reimbursement shall include interest computed at the Prime Rate based on the number of days from the end of the relevant fiscal quarter to the date of reimbursement under this Section 10.02(e). During the first month of each fiscal quarter in which it expects to incur costs for which reimbursement may be sought under this Section 10.02(e), the Controlling Company will provide the Non-Controlling Company with a good faith estimate of such costs.

Effective Date; Termination of Prior Intercompany Tax Allocation Agreements. This Agreement shall be effective as of the date hereof. As of the date hereof, (i) all prior intercompany Tax allocation agreements or arrangements between one or more members of the Houston Group, on the one hand, and one or more members of the Everett Group, on the other hand, shall be terminated; and (ii) amounts due under such agreements as of the date hereof shall be settled as of the date hereof. Upon such termination and settlement, no further payments by or to Houston or by or to Everett, with respect to such agreements shall be made, and all other rights and obligations resulting from such agreements between the Companies and their Affiliates shall cease at such time.

Survival of Obligations. The representations, warranties, covenants and agreements set forth in this Agreement shall be unconditional and absolute and shall remain in effect without limitation as to time.

Treatment of Payments; Tax Gross Up.

Treatment of Tax Indemnity and Tax Benefit Payments. In the absence of any change in Tax treatment under the Code or other applicable Tax Law,

(a) any Tax indemnity payments made by a Company under this Agreement shall be treated for Tax purposes by the Payor and the recipient as distributions or capital contributions, as appropriate, occurring immediately before the Distribution (but only to the extent the payment does not relate to a Tax allocated to the Payor in accordance with Section 1552 of the Code or the regulations thereunder or Treasury Regulation Section 1.1502-33(d) (or under corresponding principles of other applicable Tax Laws)) or as payments of an assumed or retained liability, and

(b) any Tax Benefit payments made by a Company under Section 5, shall be treated for Tax purposes by the Payor and the recipient as distributions or capital contributions, as appropriate, occurring immediately before the Distribution (but only to the extent the payment does not relate to a Tax allocated to the Payor in accordance with Section 1552 of the Code or the regulations thereunder or Treasury Regulation Section 1.1502-33(d) (or under corresponding principles of other applicable Tax Laws)) or as payments of an assumed or retained liability.

30

Tax Gross Up. If notwithstanding the manner in which Tax indemnity payments and Tax Benefit payments were reported, there is an adjustment to the Tax liability of a Company as a result of its receipt of a payment pursuant to this Agreement (disregarding for these purposes any such adjustment which arises solely as a result of a failure of the recipient Company to distribute such payment in the manner described in Section 361(b)(1)(A) of the Code) such payment shall be appropriately adjusted so that the amount of such payment, reduced by all Income Taxes payable with respect to the receipt thereof (but taking into account all correlative Tax Benefits resulting from the payment of such Income Taxes), shall equal the amount of the payment which the Company receiving such payment would otherwise be entitled to receive pursuant to this Agreement.

Interest Under This Agreement. Anything herein to the contrary notwithstanding, to the extent one Company (“Indemnitor”) makes a payment of interest to another Company (“Indemnitee”) under this Agreement with respect to the period from the date that the Indemnitee made a payment of Tax to a Tax Authority to the date that the Indemnitor reimbursed the Indemnitee for such Tax payment, the interest payment shall be treated as interest expense to the Indemnitor (deductible to the extent provided by law) and as interest income by the Indemnitee (includible in income to the extent provided by law). The amount of the payment shall not be adjusted to take into account any associated Tax Benefit to the Indemnitor or increase in Tax to the Indemnitee.

Disagreements.

Discussion. The Companies mutually desire that friendly collaboration will continue between them. Accordingly, they will try, and they will cause their respective Group members to try, to resolve in an amicable manner all disagreements and misunderstandings connected with their respective rights and obligations under this Agreement, including any amendments hereto. In furtherance thereof, in the event of any dispute or disagreement (a “Dispute”) between any member of the Houston Group and any member of the Everett Group as to the interpretation of any provision of this Agreement or the performance of obligations hereunder, the Tax departments of the Companies shall negotiate in good faith to resolve the Dispute.

Escalation. If such good faith negotiations do not resolve the Dispute, then the matter, upon written request of either Company, will be referred for resolution to representatives of the Companies at a senior level of management of the Companies pursuant to the procedures set forth in Section 8.2 of the Separation and Distribution Agreement.

Referral to Tax Advisor for Computational Disputes. Notwithstanding anything to the contrary in Section 14, with respect to any Dispute involving computational matters, if the Companies are not able to resolve the Dispute through the discussion process set forth in Section 14.01, then the Companies

31

shall not refer the dispute to the escalation process set forth in Section 14.02, but rather the Dispute will be referred to a Tax Advisor acceptable to each of the Companies to act as an arbitrator in order to resolve the Dispute. In the event that the Companies are unable to agree upon a Tax Advisor within fifteen (15) Business Days following the completion of the discussion process, the Companies shall each separately retain an independent, nationally recognized law or accounting firm (each, a “Preliminary Tax Advisor”), which Preliminary Tax Advisors shall jointly select a Tax Advisor on behalf of the Companies to act as an arbitrator in order to resolve the Dispute. The Tax Advisor may, in its discretion, obtain the services of any third-party appraiser, accounting firm or consultant that the Tax Advisor deems necessary to assist it in resolving such disagreement. The Tax Advisor shall furnish written notice to the Companies of its resolution of any such Dispute as soon as practical, but in any event no later than thirty (30) Business Days after its acceptance of the matter for resolution. Any such resolution by the Tax Advisor will be conclusive and binding on the Companies. Following receipt of the Tax Advisor’s written notice to the Companies of its resolution of the Dispute, the Companies shall each take or cause to be taken any action necessary to implement such resolution of the Tax Advisor. Each Company shall pay its own fees and expenses (including the fees and expenses of its representatives) incurred in connection with the referral of the matter to the Tax Advisor (and the Preliminary Tax Advisors, if any). All fees and expenses of the Tax Advisor (and the Preliminary Tax Advisors, if any) in connection with such referral shall be shared equally by the Companies.

Injunctive Relief. Nothing in this Section 14 will prevent either Company from seeking injunctive relief if any delay resulting from the efforts to resolve the Dispute through the process set forth above could result in serious and irreparable injury to either Company. Notwithstanding anything to the contrary in this Agreement, Houston and Everett are the only members of their respective Group entitled to commence a dispute resolution procedure under this Agreement, and each of Houston and Everett will cause its respective Group members not to commence any dispute resolution procedure other than as provided in this Section 14.

Expenses. Except as otherwise provided in this Agreement, each Company and its Affiliates shall bear their own expenses incurred in connection with preparation of Tax Returns, Tax Contests, and other matters related to Taxes under the provisions of this Agreement.

All notices, requests, claims, demands and other communications under this Agreement shall be in writing and shall be given or made (and shall be deemed to have been duly given or made upon receipt) by delivery in person, by overnight courier service, by facsimile or electronic transmission with receipt confirmed (followed by delivery of an original via overnight courier service) or by registered or certified mail (postage prepaid, return receipt requested) to the respective Parties at the following addresses (or at such other address for a Party as shall be specified in a notice given in accordance with this Section 16.01):

A Party is not prevented from enforcing any right, remedy or condition in the Party’s favor because of any failure or delay in exercising any right or remedy or in requiring satisfaction of any condition, except to the extent that the Party

33

specifically waives the same in writing. A written waiver given for one matter or occasion is effective only in that instance and only for the purpose stated. A waiver once given is not to be construed as a waiver for any other matter or occasion. Any enumeration of a Party’s rights and remedies in this Agreement is not intended to be exclusive, and a Party’s rights and remedies are intended to be cumulative to the extent permitted by law and include any rights and remedies authorized in law or in equity.

Severability. If any provision of this Agreement or the application thereof to any Person or circumstance is determined by a court of competent jurisdiction to be invalid, void or unenforceable, the remaining provisions hereof or thereof, or the application of such provision to Persons or circumstances or in jurisdictions other than those as to which it has been held invalid or unenforceable, shall remain in full force and effect and shall in no way be affected, impaired or invalidated thereby. Upon such determination, the Parties shall negotiate in good faith in an effort to agree upon such a suitable and equitable provision to effect the original intent of the parties.

Authority. Each of the Parties represents to the other that (a) it has the corporate or other requisite power and authority to execute, deliver and perform this Agreement, (b) the execution, delivery and performance of this Agreement have been duly authorized by all necessary corporate or other action, (c) it has duly and validly executed and delivered this Agreement, and (d) this Agreement is a legal, valid and binding obligation, enforceable against it in accordance with its terms, subject to applicable bankruptcy, insolvency, reorganization, moratorium or other similar laws affecting creditors’ rights generally and general equity principles.

Further Action. The Parties shall execute and deliver all documents, provide all information, and take or refrain from taking action as may be necessary or appropriate to achieve the purposes of this Agreement, including the execution and delivery to the other Parties and their Affiliates and representatives of such powers of attorney or other authorizing documentation as is reasonably necessary or appropriate in connection with Tax Contests (or portions thereof) under the control of such other Parties in accordance with Section 10.

Integration. This Agreement, together with each of the exhibits and schedules appended hereto constitutes the final agreement among the Parties, and is the complete and exclusive statement of the Parties’ agreement on the matters contained herein. All prior and contemporaneous negotiations and agreements among the Parties with respect to the matters contained herein are superseded by this Agreement, as applicable. In the event of any inconsistency between this Agreement and the Separation and Distribution Agreement, or any other agreements relating to the transactions contemplated by the Separation and Distribution Agreement, with respect to matters addressed herein, the provisions of this Agreement shall control.

No Double Recovery. No provision of this Agreement shall be construed to provide an indemnity or other recovery for any costs, damages, or other amounts for which the damaged Party has been fully compensated under any other provision of this Agreement or under any other agreement or action at law or equity. Unless expressly required in this Agreement, a Party shall not be required to exhaust all remedies available under other agreements or at law or equity before recovering under the remedies provided in this Agreement.

Counterparts. This Agreement may be executed in one (1) or more counterparts (including by electronic or .pdf transmission), and by each Party in separate counterparts, each of which when executed shall be deemed to be an original but all of which taken together shall constitute one and the same agreement. Delivery of any signature page by facsimile, electronic or .pdf transmission shall be binding to the same extent as an original signature page.

Governing Law. This Agreement shall be governed by and construed and interpreted in accordance with the Laws of the State of Delaware without giving effect to the principles of conflicts of law thereof.

Jurisdiction. If any dispute arises out of or in connection with this Agreement, except as expressly contemplated by another provision of this Agreement, the Parties irrevocably (and the Parties will cause each other member of their respective Group to irrevocably) (i) agrees that any dispute shall be subject to the exclusive jurisdiction of the state and federal courts located in the State of Delaware, (ii) waives any claims of forum non conveniens and agrees to submit to the jurisdiction of such courts and (iii) agrees that service of any process, summons, notice or document by U.S. registered mail to its respective address set forth in Section 16.01 shall be effective service of process for any litigation brought against it in any such court or for the taking of any other acts as may be necessary or appropriate in order to effectuate any judgment of said courts.

Amendment. No provision of this Agreement (except as otherwise provided therein) may be amended or modified except by a written instrument signed by each of the parties hereto or thereto, as applicable.

Houston or Everett Affiliates. If, at any time, Houston or Everett acquires or creates one or more affiliates that are includable in the Houston Group or Everett Group, as the case may be,

35

they shall be subject to this Agreement and all references to the Houston Group or Everett Group, as the case may be, herein shall thereafter include a reference to such affiliates. For the avoidance of doubt, as of the Effective Time, this Agreement shall be binding on Chicago and Chicago shall be subject to the obligations and restrictions imposed on Everett hereunder, and any restrictions applicable to Everett shall apply to Chicago mutatis mutandis.

Successors. This Agreement shall be binding on and inure to the benefit of any successor by merger, acquisition of assets, or otherwise, to any of the Parties hereto (including but not limited to any successor of Houston or Everett succeeding to the Tax attributes of either under Section 381 of the Code), to the same extent as if such successor had been an original Party to this Agreement.

Injunctions. The Parties acknowledge that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with its specific terms or were otherwise breached. The Parties hereto shall be entitled to an injunction or injunctions to prevent breaches of the provisions of this Agreement and to enforce specifically the terms and provisions hereof in any court having jurisdiction, such remedy being in addition to any other remedy to which they may be entitled at law or in equity.
