PAYMENT OF TAXES WMS shall pay all taxes due (or receive all refunds) in connection with the filing of WMS's consolidated federal income tax returns for all taxable periods beginning before the Distribution or Contribution Dates, and with any request for extension of time within which to file such returns. 2. PREDISTRIBUTION TAX RETURNS All consolidated federal income tax returns that include a member of the WMS Group and/or the Hotel Group that are required to be filed for periods beginning before the Distribution or Contribution Dates shall be prepared and filed by WMS. The Hotel Group shall, for such taxable periods, provide WMS with (i) true and correct separate federal income tax returns for each member of the Hotel Group, and (ii) a true and correct reconciliation of book income to federal taxable income for each member of the Hotel Group. 3. ALLOCATION OF TAX ATTRIBUTES All tax attributes of the WMS Group will be allocated among WMS (and its subsidiaries other than the Hotel subsidiaries), and the Hotel subsidiaries, in accordance with the Regulations promulgated pursuant to Section 1502 or analogous provisions of state, local, or foreign law. 4. CARRYBACKS OF TAX ATTRIBUTES Except as provided in Section 8(c) hereof, if, for any taxable year beginning on or after the Distribution or Contribution Dates, Hotel or any Member of the Hotel Group recognizes a tax attribute that Hotel or such Member of the Hotel Group, under the applicable provisions of the Code and Regulations promulgated under Section 1502 thereof, is permitted or required to carry back to a prior taxable year of the WMS Group or the prior taxable year of a Member of the WMS Group, WMS shall, at Hotel's cost and expense, file appropriate 2 refund claims within a reasonable period after being requested by Hotel. WMS (or the Member of the WMS Group receiving such refund) shall promptly remit to Hotel any refunds it receives with respect to any tax attribute so carried back. 5. TAX AUDITS AND CONTROVERSIES (a) WMS, at its own expense, shall have the exclusive authority to represent each member of the Hotel Group before the Internal Revenue Service ("IRS") or any other governmental agency or authority or before any court with respect to any matter affecting the tax liability of any member of either the WMS Group or the Hotel Group for any period beginning before the Distribution or Contribution Dates with respect to any return for which WMS has filing responsibility. Such representation shall include, but shall not be limited to exclusive control over (i) any response to any examination of any such tax returns and (ii) any contest through a final determination of any issue included in any such tax return that includes a member of the WMS Group including, but not limited to, (A) whether and in what forum to conduct such contest and (B) except as otherwise provided in this Section 5, whether and on what basis to settle such contest. WMS shall give timely notice to Hotel of any inquiry, the assertion of any claim or the commencement of any suit, action or proceeding to the extent that any issue raised therein could directly or indirectly adversely impact any Member of the Hotel Group and will give Hotel such information with respect thereto as Hotel may reasonably request. Upon notice to WMS, Hotel may, at its own expense, participate in any such inquiry, audit or other administrative proceeding and to the extent any such inquiry, audit or other administrative proceeding relates to an item of the Hotel Group, then Hotel may assume at its own expense the defense or prosecution, as the case may be, of any inquiry, audit, suit or action or proceeding provided that each Hotel representative is reasonably satisfactory to WMS and Hotel shall thereafter consult with WMS upon WMS's request for such consultation from time to time, with respect to such proceeding. (b) In the event either WMS or Hotel notifies the other party in writing that it wishes to settle any audit, inquiry, suit, action or proceeding (each an "Action") affecting the tax liability of the other party (including by application of this Agreement), such other party shall have the right (by giving written notice to the party wishing to settle the Action within a reasonable amount of time, considering all the facts and circumstances, of having received notice of the intention to settle), to prohibit such settlement, in which case the party favoring settlement shall have the right (within thirty (30) days of receipt of the other party's written notice prohibiting the settlement) to pay to the other party (or receive from the other party) an amount (a "Settlement Amount") equal to the aggregate amount which it would have paid (or received) after application of each provision of this Agreement other than this Section 5(b), in full satisfaction of the Action and its obligation to pay amounts (or right to receive amounts) as provided in this Agreement. The party opposing the settlement shall thereafter control, in its sole and absolute discretion, the further defense and disposition of the Action, and shall be fully and wholly liable for all taxes (and receive any refund of taxes) resulting therefrom and shall indemnify and hold harmless the party favoring the settlement from any and all liability for taxes that results from the ultimate resolution of the Action in excess of the Settlement Amount. The 3 party opposing the settlement shall have no obligation or duty to reimburse or refund to the other party any portion of the Settlement Amount, regardless of the ultimate resolution of the Action. The party favoring the settlement shall have the right, at its own expense, to participate in any Action for which the other party has assumed control under this Section 5(b). If the party favoring settlement does not on a timely basis exercise its right to make or receive a settlement amount, the obligation of WMS and Hotel under this Agreement shall be determined as if the proposed settlement did not exist (e.g., the party favoring settlement cannot settle an Action without again complying with the procedure set forth in this Section 5(b)). 6. RETENTION OF BOOKS AND RECORDS WMS and the Hotel Subsidiaries each agree to retain all tax records, related schedules and work papers, and all material records and other documents relating thereto existing on the date hereof or created through or with respect to taxable periods ending on or before the Distribution Date or the Contribution Date, until the later of (i) the expiration of the statute of limitations (including extensions) of the taxable year to which such tax returns and other documents relate or (ii) ten years from the date hereof. 7. COOPERATION REGARDING RETURN FILINGS, EXAMINATIONS AND CONTROVERSIES (a) In addition to any obligations imposed pursuant to the Plan of Reorganization and Distribution Agreement, Hotel and each Member of the Hotel Group shall fully cooperate with WMS and its representatives, in a prompt and timely manner, in connection with (A) the preparation and filing of and (B) any inquiry, audit, examination, investigation, dispute, or litigation involving any tax returns filed or required to be filed by or for any member of the WMS Group for any taxable period beginning before the Distribution Date or the Contribution Date. Such cooperation shall include, but not be limited to, (x) the execution and delivery to WMS by the appropriate Hotel Group Member of any power of attorney or other necessary document to allow WMS and its counsel to participate on behalf of Hotel or any Hotel Group Member in any action and to assume the defense or prosecution, as the case may be, of any action, pursuant to the terms of Section 5 of this Agreement and (y) making available to WMS, during normal business hours, and within sixty (60) days of any request therefor, all books, records and information (which books, records and information may be copied by WMS at its expense) and the assistance of all officers and employees, reasonably necessary or useful in connection with any Action, including the preparation of the consolidated federal tax return for the Current Period. (b) In addition to any obligations imposed pursuant to the Plan of Reorganization and Distribution Agreement, WMS and each Member of the WMS Group shall fully cooperate with Hotel and its representatives, in a prompt and timely manner, in connection with (A) the preparation and filing of and (B) any inquiry, audit, examination, investigation, dispute, or litigation involving any tax returns filed or required to be filed by or for any Member of the Hotel Group for any taxable period beginning before the Distribution or Contribution Dates. Such cooperation shall include, but not be limited to, (x) the execution and delivery to 4 Hotel by the appropriate WMS Group member of any power of attorney or other necessary document to allow Hotel and its counsel to participate on behalf of WMS or any WMS Group member in any action and to assume the defense or prosecution, as the case may be, of any action, pursuant to the terms of Section 5(a) of this Agreement and (y) making available to Hotel, during normal business hours, and within sixty (60) days of any request therefor, all books, records and information (which books, records, and the assistance of all officers and employees, reasonably necessary or useful in connection with any action, including the preparation of the consolidated federal tax return for the Current Period). 8. REFUNDS AND SUBSEQUENT ADJUSTMENTS (a) If part or all of an unused consolidated net operating loss or tax credit is allocated to a Member of the Hotel Group pursuant to Section 1.1502-79 of the Regulations, and it is carried back or forward to a year in which such Member actually filed or files a separate income tax return or a consolidated federal income tax return with another affiliated group, any refund or reduction in tax liability arising from the carryback or carryover shall be retained by such Member. Notwithstanding the preceding sentence, WMS shall determine whether an election shall be made not to carryback any consolidated net operating loss ("NOL") arising in a consolidated return year (including any portion allocated to a Member under Section 1.1502-79) in accordance with Section 172(b)(3). (b) If the consolidated federal income tax liability is adjusted for the Prior Periods or the Current Period, whether by means of an amended return, claim for refund, or after an audit by the IRS, WMS shall be solely responsible for the payment of any additional tax liability and will retain any tax refunds. WMS shall indemnify the Hotel Subsidiaries against any liability for such taxes including any liability asserted pursuant to Regulation Section 1.1502-6 and Hotel and the Hotel Subsidiaries will promptly pay over to WMS any tax refunds received with respect to such periods. (c) If Hotel or a Member of the Hotel Group shall be entitled to an Income Tax Benefit (as herein defined) for any taxable period ending after the Distribution Date or the Contribution Date on account of a redetermination of the tax treatment of any item of income, gain, deduction, loss or credit in the consolidated federal income tax return for the Prior Periods or the Current Period, then such Hotel Group Member shall (i) not elect to waive the carryback period pursuant to Section 172(b)(3) with respect to any NOL generated or increased as a result of such Income Tax Benefit and (ii) pay over to WMS the amount of any Income Tax Reduction (as herein defined) as a result of such Income Tax Benefit. In addition, notwithstanding Section 4 of this Agreement, WMS shall retain the portion of any refund received with respect to the carryback of an NOL (or other tax attribute) to a prior taxable year of the WMS Group, to the extent such NOL (or other tax attribute) resulted from the realization of such Income Tax Benefit. For purposes of this Section 8(c): 5 (A) "Income Tax Benefit" shall mean any decrease in any item of income, gain or investment tax credit recapture or any increase in any item of deduction (including depletion, depreciation or amortization deductions which result from an addition to basis of any asset); and (B) "Income Tax Reduction" shall mean (i) with respect to any taxable period for which an income tax return shall have been filed, receipt of a refund of income tax previously paid with respect to such period plus interest thereon as provided by law (or any reduction in income tax liability in lieu of such refund and interest); and (ii) with respect to any taxable period for which an income tax return shall not have been filed, a reduction in the income tax that would otherwise have been payable with respect to such period. 9. STATE AND LOCAL TAXES Each Member shall timely file its own returns and pay its own state and local income and franchise taxes; provided, however, that if any two or more Members are required or elect, or WMS elects or causes any two or more Members to elect, to file combined or consolidated (or similar) income tax returns for any taxable year under any state or local income tax law, the financial consequences of filing such returns among such Members shall be determined in a manner as similar as practicable to those provided herein for federal income tax purposes. 10. EFFECTIVE DATE This Agreement shall become effective upon the Distribution and shall continue in effect until otherwise agreed in writing by WMS and Hotel or their successors. 11. MISCELLANEOUS PROVISIONS (a) All material including, but not limited to, returns, supporting schedules, work papers, correspondence, and other documents relating to the consolidated federal income tax returns filed for a taxable year during which this Agreement was in effect shall be made available to any party to this Agreement during regular business hours until the later of (i) the expiration of the statute of limitations (including extensions) of the taxable year to which such tax returns and other documents relate or (ii) ten years from the date hereof. (b) The provisions of this Agreement shall be administered by the Chief Executive Officer of WMS. A dispute between the parties with respect to the operation or interpretation of this Agreement shall be decided by three arbitrators who must all be certified public accountants or attorneys specializing in tax law. WMS and Hotel shall each choose an arbitrator who will choose a third arbitrator. The court of arbitrators shall be held in the State 6 of Illinois in the city of Chicago. The losing party shall bear the cost of arbitration including all fees for attorneys and accountants. (c) Any alteration, modification, addition, deletion, or other change in the consolidated income tax return provisions of the Code or the regulations thereunder shall automatically be applied to this Agreement mutatis mutandis. (d) This Agreement shall bind successors and assigns of the parties hereto; but no assignment shall relieve any party's obligations hereunder without the written consent of the other parties.
