Payments under this agreement attributable to the Purchased Assets shall be payment obligations of, and shall be made to, the applicable Starwood selling subsidiary and the ILG Subsidiary Buyer, as the case may be.

Section 3.03 Tax Characterization of and Adjustments to Payments.

(a) Except as provided in Section 3.03(b), Starwood and Vistana agree to treat any payment required by this Agreement (other than payments with respect to interest accruing after the Distribution Date) as either a contribution by Starwood to Vistana or a distribution by Vistana to Starwood, as the case may be, occurring immediately prior to the Distribution.

(b) The Parties agree to treat any payment required by this Agreement in respect of the Purchased Assets as an adjustment to the purchase price of such Purchased Assets for Tax purposes.

(c) Notwithstanding the foregoing, the amount that any Indemnifying Party is or may be required to provide indemnification to or on behalf of any Indemnified Party pursuant to Article III of this Agreement shall be (i) decreased to take into account the actual Tax Benefit to the Indemnified Party (or any of its affiliates) arising from the incurrence or payment of the relevant indemnified item (which Tax Benefit would not have arisen or been allowable but for such indemnified item), and (ii) increased to take into account any actual Tax Cost of the

Indemnified Party (or any of its affiliates) arising from the receipt of the relevant indemnity payment (but taking into account any actual offsetting Tax Benefits resulting from the payment of such Tax Cost).

Section 3.05 Indemnification Payments under Ancillary Agreements. To the extent that an indemnification payment is made under any Ancillary Agreement, such indemnification payment shall be decreased to take into account the Tax Benefit actually realized (whether directly or indirectly) by the indemnified party and increased to take into account any Tax Cost actually incurred (whether directly or indirectly) by the indemnified party under principles analogous to the principles described in Section 3.03 hereof.

ARTICLE IV

REFUNDS, CARRYBACKS, TIMING DIFFERENCE AND TAX ATTRIBUTES

Section 4.01 Refunds and Credits.

(a) Except as provided in Section 4.02, Starwood shall be entitled to all Refunds of Taxes for which Starwood is responsible pursuant to Article III, and Vistana or ILG, as the case may be, shall be entitled to all Refunds of Taxes for which such Party is responsible pursuant to Article III. 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 Article III, 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 (or any of member of such Party’s Group) to a Taxing Authority or to the other Party (and reduced by the amount of payments received from the other Party) pursuant to Articles II and III hereof with the Tax liability of such Party as determined under Section 2.06, taking into account the facts as utilized for purposes of claiming such Refund. If a Party (or any member of its Tax Group) receives a Refund to which the other Party is entitled pursuant to this Agreement, such Party shall pay the amount to which such other Party is entitled within ten (10) days after the receipt of the Refund.

(b) In the event of an Adjustment relating to Taxes for which one Party is responsible pursuant to Article III which would have given rise to a Refund but for an offset

against the Taxes for which the other Party (or a member of its Tax Group) is or may be responsible pursuant to Article III (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 (or such Tax Group member) plus interest at the rate set forth in Section 6621(a)(1) 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.

(c) Notwithstanding Section 4.01(a), to the extent that a Party (or any member of its Tax Group) applies or causes to be applied an overpayment of Taxes as a credit toward or a reduction in Taxes otherwise payable (or a Taxing Authority requires such application in lieu of a Refund) and such overpayment of Taxes, if received as a Refund, would have been payable by such Party to the other Party pursuant to this Section 4.01, such Party shall pay such amount to the other Party no later than the Due Date of the Tax Return for which such overpayment is applied to reduce Taxes otherwise payable.

(d) If Vistana or ILG, or any member of such Party’s Tax Group receives a Refund attributable to Restructuring VAT, or otherwise utilizes the benefits of a payment of Restructuring VAT (including by way of credit), Vistana or ILG, as the case may be, shall pay, or cause to be paid, to Starwood, within ten (10) days of the receipt of any such Refund or the filing of the Tax Return utilizing any such benefit the amount of such Restructuring VAT to the extent of such Refund, credit or other benefit. Vistana and ILG agree to claim, and to cause members of each Party’s Tax Group to claim, any refund, offset, credit or other allowance attributable to Restructuring VAT as soon as reasonably possible and to furnish to Starwood at Starwood’s request all information, records and assistance reasonably necessary to verify the amount of any such refund, offset, credit or other allowance.

(e) To the extent that the amount of any Refund under this Section 4.01 is later reduced by a Taxing Authority or in a Tax Proceeding, such reduction shall be allocated to the Party to which such Refund was allocated pursuant to this Section 4.01 and an appropriate adjusting payment shall be made.

Section 4.02 Carrybacks.

(a) The carryback of any loss, credit or other Tax Attribute from any Post-Closing Period shall be in accordance with the provisions of the Code and Treasury Regulations (and any applicable state, local or foreign Laws).

(b) Except to the extent otherwise consented to by Starwood or prohibited by applicable Law, Vistana (or the appropriate member of its Tax Group) shall elect to relinquish, waive or otherwise forgo the carryback of any loss, credit or other Tax Attribute from any Post-Closing Period to any Pre-Closing Period or Straddle Period with respect to members of the Vistana Group (a “Carryback”). In the event that Vistana (or the appropriate member of its Tax Group) is prohibited by applicable Law to relinquish, waive or otherwise forgo a Carryback (or Starwood consents to a Carryback), Starwood shall cooperate with

Vistana, at Vistana’s expense, in seeking from the appropriate Taxing Authority such Refund as reasonably would result from such Carryback, to the extent that such Refund is directly attributable to such Carryback, and shall pay over to Vistana the amount of such Refund, net of any Taxes imposed on the receipt of such Refund, within ten (10) days after such Refund is received; provided, however, that Vistana shall indemnify and hold the members of Starwood’s Tax Group harmless from and against any and all collateral Tax consequences and reasonable out of pocket expenses resulting from or caused by any such Carryback, including, for the avoidance of doubt, Taxes (including any penalties, interest or other charges imposed by the relevant Taxing Authority) resulting from the Final Determination of an Adjustment that results in the disallowance of or adjustment to the amount of any Carryback under this Section 4.02, and including, without limitation, the loss or postponement of any benefit from the use of Tax Attributes generated by a member of Starwood’s Tax Group if (i) such Tax Attributes expire unutilized, but would have been utilized but for such Carryback, or (ii) the use of such Tax Attributes is postponed to a later taxable period than the taxable period in which such Tax Attributes would have been utilized but for such Carryback and shall pay Starwood such amounts within ten (10) days after written notification thereof by Starwood, including reasonably satisfactory documentation setting forth the basis for, and calculation of, the amount of such Tax consequences and expenses, or within ten (10) days after resolution pursuant to Section 8.01.

Section 4.03 Tax Attributes; E&P.

(a) Subject to Section 4.03(c), as soon as reasonably practicable after the Effective Time, Starwood shall reasonably determine in good faith the allocation of Tax Attributes arising in a Pre-Closing Period to the Starwood Group and the Vistana Group in accordance with the Code and Treasury Regulations including (i) in the case of Tax Attributes other than earnings and profits, Treasury Regulations Sections 1.1502-9T(c), 1.1502-21, 1.1502-21T, 1.1502-22, 1.1502-79 and, if applicable, 1.1502-79A (and any applicable state, local and foreign Tax Laws), and (ii) in the case of earnings and profits, in accordance with Code Section 312(h) and Treasury Regulations Section 1.312-10(a). Subject to the preceding sentence, Starwood shall be entitled to make any determination as to (A) basis, and (B) valuation, and shall make such determinations reasonably and in good faith and consistent with Past Practice, where applicable. Starwood shall consult in good faith with Vistana regarding such allocation of Tax Attributes and determinations as to basis and valuation, and shall consider in good faith any reasonable comments received in writing from Vistana regarding such allocation and determinations. Starwood and Vistana hereby agree to compute all Taxes for Post-Closing Periods consistently with the determination of the allocation of Tax Attributes pursuant to this Section 4.03(a) unless otherwise required by a Final Determination.

(b) To the extent that the amount of any Tax Attribute is later reduced or increased by a Taxing Authority or Tax Proceeding, such reduction or increase shall be allocated to the Party to which such Tax Attribute was allocated pursuant to Section 4.03(a).

(c) Upon the written request of Vistana, Starwood shall provide Vistana, within six (6) months of receipt of such request or as soon as reasonably practicable thereafter, an allocation of earnings and profits (“E&P”) between Starwood and Vistana, and

Starwood shall allocate such E&P in accordance with Section 1.312-10(a) of the Treasury Regulations, and such allocation shall control for Tax periods beginning after the Distribution Date; provided however, that (i) Starwood shall provide Vistana a reasonable opportunity to review, and provide written comments to, such allocation of E&P, including an E&P study if an E&P study is conducted, and shall consider in good faith the reasonable comments made by Vistana and (ii) as reasonably requested by Vistana, Starwood shall provide Vistana with copies of any workpapers or other documentation that are used in connection with determining the allocations and/or reductions of E&P, including a final copy of any E&P study conducted and prepared in connection therewith.

Section 4.04 Treatment of Deductions Associated with Equity-Related Compensation.

(a) Unless otherwise prohibited by applicable Law, from and after the Distribution Date, (i) solely Starwood or any member of the Starwood Group, as the case may be, shall be entitled to claim any Tax deduction associated with (A) the exercise in any taxable period of any Starwood stock options, stock appreciation rights or any other equity award in respect of Starwood stock (“SW Equity Award”) by any Vistana Employee, (B) any cash payment made by Starwood to any Vistana Employee in respect of any SW Equity Award and (C) any other cash payments by Starwood (or for which Starwood or any member of the Starwood Group is economically responsible under the Transaction Documents) to a Vistana Employee, including any annual bonuses payable in 2016, and (ii) solely ILG or any member of the ILG Group, as the case may be, shall be entitled to claim any Tax deduction associated with (A) the exercise in any taxable period of any ILG stock option, stock appreciation rights or other equity award in respect of any ILG stock (“ILG Equity Award”) by any Vistana Employee into which a SW Equity Award is converted pursuant to the Employees Matters Agreement, (B) any cash payment made to any Vistana Employee after the Distribution Date in respect of any ILG Equity Award and (C) any other cash payments to a Vistana Employee for which ILG or any member of the ILG Group is economically responsible under the Transaction Documents.

(b) “Vistana Employee” means any person employed or formerly employed by any member of the Vistana Group at the time of the exercise, vesting, settlement disqualifying disposition or payment, as appropriate.

(c) To the extent under applicable law a Party or a member of such Party’s Tax Group is unable to claim any of the Tax deductions in Section 4.04(a) and the other Party or a member of such other Party’s Tax Group obtains a Tax deduction or a Tax Benefit in respect of a Tax period for which such other Party is responsible for Taxes, then such other Party shall make a cash payment to the first Party in an amount equal to the reduction in Taxes otherwise required to be paid as a result of such Tax deduction or Tax Benefit.

Section 4.05 Timing Differences. If pursuant to a Final Determination an Adjustment (i) increases the amount of liability for any Taxes for which a member of the Starwood Group is responsible hereunder and a Tax Benefit is made allowable to Vistana or ILG (or a member of such Party’s Tax Group) for any Tax period after the Effective Time, which Tax

Benefit would not have arisen or been allowable but for such Adjustment, and which Tax Benefit reduces Taxes in respect of a Tax period for which Vistana or ILG (or a member of such Party’s Tax Group), as the case may be, is liable (and for which no member of the Starwood Group is liable) or (ii) increases the amount of liability for any Taxes for which a member of the Vistana Group or ILG Group is responsible hereunder and a Tax Benefit is made allowable to Starwood or a member of its Tax Group for any Tax period prior to the Effective Time, which Tax Benefit would not have arisen or been allowable but for such Adjustment, and which Tax Benefit reduces Taxes in respect of a Tax period which Starwood or a member of its Tax Group is liable (and for which no member of the Vistana Group or ILG Group is liable), then Vistana or ILG, or Starwood, as the case may be, shall make a payment to either Starwood, or Vistana or ILG, as appropriate, within thirty (30) days of the date that such paying Party (or any of its Tax Group members) actually receives such Tax Benefit (determined by comparing its (and its Tax Group members’) Tax liability with and without the Tax consequences of the Adjustment), which payment shall not exceed the increase in the amount of liability for any Taxes resulting from such Adjustment, for which a member of the Starwood Group, Vistana Group or ILG Group as the case may be, is responsible hereunder.

Section 4.06 Section 336(e) Election.

(a) Subject to Section 4.06(e), pursuant to Treasury Regulation Sections 1.336-2(h)(1) and 1.336-2(j), Starwood shall make a timely actual or protective election (as shall be appropriate) under Section 336(e) of the Code and the Treasury Regulations issued thereunder for Vistana and any other Vistana Entity for which Starwood determines to make an election with respect to the Distribution (a “Section 336(e) Election”). The Parties hereto expressly agree that any Section 336(e) Election would provide that such Section 336(e) Election is intended to be effective only in a situation where the Distribution is (A) described in Section 355(c)(2)(A)(ii) or Section 361(c)(2)(A)(ii) of the Code or (B) not a transaction to which Sections 354, 355 or 361 of the Code applies and the fair market value of the Vistana stock is not less than Starwood’s tax basis in the Vistana stock. Starwood, ILG, and Vistana shall cooperate in making such Section 336(e) Election, including filing any statements, amending any Tax Returns or taking such other action reasonably necessary to carry out the Section 336(e) Election. For the avoidance of doubt, this Agreement permits the making of a protective election under Section 336(e) of the Code but is intended to constitute a written, binding agreement to make a Section 336(e) Election within the meaning of Treasury Regulation Section 1.336-2(h)(1)(i) so long as and only if the Distribution is (A) described in Section 355(c)(2)(A)(ii) or Section 361(c)(2)(A)(ii) of the Code or (B) not a transaction to which Sections 354, 355 or 361 of the Code applies and the fair market value of the Vistana stock is not less than Starwood’s tax basis in the Vistana stock. In connection with the Section 336(e) Election, Starwood may make an election under Treasury Regulation Section 1.1502-13(f)(5)(ii). If Starwood determines that Section 336(e) applies with respect to the Distribution (including Starwood’s determination after or as a result of an IRS inquiry or challenge), Starwood shall provide Vistana with a proposed determination of the “Aggregate Deemed Asset Disposition Price” and the “Adjusted Grossed-Up Basis” (each as defined under applicable Treasury Regulations) and the allocation of such Aggregate Deemed Asset Disposition Price and Adjusted Grossed-Up Basis among the disposition date assets of Vistana and its subsidiaries, each in accordance with the applicable

provisions of Section 336(e) of the Code and applicable Treasury Regulations (the “Section 336(e) Allocation Statement”). Starwood shall prepare the Section 336(e) Allocation Statement based on the advice of Ernst & Young LLP. Within thirty (30) days after Vistana’s receipt of the Section 336(e) Allocation Statement, Vistana may provide comments to Starwood to the Section 336(e) Allocation Statement and Starwood shall consider such comments in good faith; provided, however, that Starwood shall make the final determination regarding incorporation of Vistana’s comments in the Section 336(e) Allocation Statement. No member of the ILG Group or the Vistana Group shall take any position inconsistent with the Section 336(e) Election including the Section 336(e) Allocation Statement except as may be required by a Final Determination.

(b) Except as otherwise provided in Section 4.06(e), if Starwood files a Tax Return reflecting the position that, or there is a Final Determination that, the Distribution fails to qualify as a Tax-free spin-off under Sections 368(a)(1)(D) and 355 of the Code, including taxation even if only by reason of the application of Section 355(e) of the Code to the Distribution, and Taxes resulting therefrom are a Starwood Tax, then any Tax Benefit actually realized by Vistana or any member of its Tax Group as a result of the Section 336(e) Election for any Tax period after the Effective Time, whether by virtue of an increase in the Tax basis in such member’s assets or otherwise, shall be paid by Vistana to Starwood within thirty (30) days of the date that Vistana or any member of its Tax Group actually receives such Tax Benefit. The Parties agree to negotiate in good faith to have Vistana make a single payment to Starwood in lieu of the payments otherwise required under this Section 4.06(b).

(c) Within ten (10) days after Vistana becomes aware of the commencement of a Tax Proceeding with respect to any item which has given or could give rise to a payment under Section 4.06(b) (a “Section 336(e) Tax Benefit Item”) or any item for which Starwood is responsible pursuant to the indemnity under Section 4.06(d) below, Vistana shall notify Starwood of such Tax Proceeding, and thereafter shall promptly forward or make available to Starwood copies of notices and communications relating to such Tax Proceeding to the extent relating to such Section 336(e) Tax Benefit Item or such indemnity obligation. The failure of Vistana to notify Starwood of the commencement of such Tax Proceeding within such ten (10) day period or promptly forward any further notices or communications shall not relieve Starwood of any obligation which it may have to Vistana under Section 4.06(d) except to the extent that Starwood is materially prejudiced by such failure. If Starwood has acknowledged in writing its liability for all of the Taxes to the extent relating to such Section 336(e) Tax Benefit Item or such tax indemnity obligation, Starwood shall be entitled to contest, compromise, control and settle any adjustment or deficiency proposed, asserted or assessed with respect to any Section 336(e) Tax Benefit Item and any item for which Starwood is responsible pursuant to the indemnity under Section 4.06(d) below; provided, that Starwood shall keep Vistana informed in a timely manner of all actions proposed to be taken by Starwood; and provided further that, to the extent such Tax Proceeding could materially adversely affect the amount of Taxes for which Vistana is responsible pursuant to Article IV, Starwood shall not settle any such Tax Proceeding without the prior written consent of Vistana, which shall not be unreasonably withheld, conditioned or delayed; provided that Starwood may settle any such Tax Proceeding in its sole discretion without the prior written consent of Vistana if Starwood agrees to indemnify Vistana

for the incremental Taxes for which Vistana is responsible arising as a result of the Tax Proceeding (not taking into account as an incremental Tax any Tax attributable to a reduction in any Section 336(e) Tax Benefit Item, whether by virtue of a reduction in the Tax basis or otherwise, if and to the extent such reduction would result in a reduction in Vistana’s payment obligation to Starwood under Section 4.06(b)).

(d) Starwood shall indemnify and hold Vistana harmless from and against any and all Taxes attributable to a Tax Proceeding if and to the extent such Taxes result from an adjustment to (i) a Section 336(e) Tax Benefit Item or (ii) the Section 336(e) Election, together with any costs (including reasonable attorneys’ fees and expenses) related to such indemnified Taxes; provided that such indemnity obligation shall be net of payments that would have been or would be made under Section 4.06(b) (and payments that would have been made in the past under Section 4.06(b) but were not made) by Vistana to Starwood, if such Section 336(e) Tax Benefit Item, including basis, had continued to exist. Starwood shall pay Vistana such amounts within ten (10) days after written notification thereof by Vistana, including reasonably satisfactory documentation setting forth the basis for, and calculation of, the amount of such Taxes and the amount of any netting in respect of Section 4.06(b) payments as discussed above, and expenses, or within ten (10) days after resolution pursuant to Section 8.01. Notwithstanding the foregoing, Starwood’s indemnity obligation in this Section 4.06(d) shall not apply in the event that Taxes attributable to the failure of the Contribution and Distribution, taken together, to qualify as a tax-free reorganization pursuant to Sections 355 (including Section 355(e)), 361 and 368(a)(1)(D), including Taxes arising even if only by reason of the application of Section 355(e) of the Code to the Distribution, are a Vistana Tax.

(e) Starwood may, in its discretion, decide not to make an election under Section 336(e) of the Code if Starwood has agreed in writing to waive its right to indemnity from Vistana hereunder for Taxes attributable to the failure of the Contribution and Distribution, taken together, to qualify as a tax-free reorganization pursuant to Sections 355 (including Section 355(e)), 361 and 368(a)(1)(D), including Taxes arising even if only by reason of the application of Section 355(e) of the Code to the Distribution. Starwood shall use commercially reasonable efforts to inform ILG whether it intends to make an election under Section 336(e) of the Code by December 31, 2016. If Starwood decides not to make an election under Section 336(e) of the Code pursuant to this Section 4.06(e), Starwood shall inform ILG in writing of such decision by February 27, 2017.

Section 4.07 SVO Conversion. Starwood may, in its discretion, submit an IRS Ruling Request to the IRS regarding an SVO Conversion. In such event, ILG shall use commercially reasonable efforts to assist Starwood in obtaining the ruling. If the SVO Conversion is not effected, whether because such ruling is not obtained or because Starwood in its discretion decides not to convert SVO to a limited liability company and/or effect the SVO Conversion, ILG will pay Starwood an amount equal to eighty-five percent (85%) of any Tax Benefit actually realized (in any period, provided that such Tax Benefit reduces Taxes for which Vistana, and not Starwood, is responsible hereunder) by Vistana or any member of its Tax Group as a result of SVO not being treated as liquidating for U.S. federal Income Tax purposes (including, without limitation, any Tax Benefits relating to losses in respect of a Tax election to

treat Westin SVO Los Cabos, S. de R.L. de CV as a partnership for U.S. federal Income Tax purposes and in respect of any transfer of the stock of Caledonia Properties N.V. and Caledonia Development R Management) within thirty (30) days of the date that Vistana or any member of its Tax Group actually receives such Tax Benefit. The amount of such Tax Benefit shall be the amount by which (i) the Vistana Group’s actual Tax liability (treating SVO as a corporation for U.S. federal Income Tax purposes before and immediately after the Distribution Date) is less than (ii) the Tax liability the Vistana Group would have incurred had SVO “liquidated” (within the meaning and as determined for purposes of Section 332 of the Code) prior to the Distribution Date and such “liquidation” of SVO had been respected for U.S. federal Income Tax purposes.

Section 4.08 Installment Sale. Starwood may, in its discretion, elect out of the installment method under Section 453(d) of the Code (or any comparable or analogous provision under state or local Law) with respect to all or any portion of installment sales reported during the tax years beginning January 1, 2015 or January 1, 2016 (the “Installment Sales”) by SVO or its Subsidiaries, which otherwise qualify for installment sale treatment under Section 453(a) of the Code (the “Section 453(d) Election”), provided that ILG consents to such Section 453(d) Election, which consent shall not be unreasonably withheld, conditioned or delayed, and which consent shall be given by ILG if the Aggregate Deemed Asset Disposition Price of Vistana would not reasonably be expected to exceed the Adjusted Grossed-Up Basis of Vistana (such excess, the “Excess”) by more than $100,000,000, assuming the Section 453(d) Election is made with respect to the Installment Sales so identified by Starwood. For purposes of determining the Aggregate Deemed Asset Disposition Price under this Agreement, ILG consents that Starwood may treat the fair market value of the Vistana stock on the Distribution Date as being equal to the fair market value of the ILG stock received in the Merger, and the fair market value of such ILG stock as being equal to the trading price of the ILG stock on the Distribution Date (or, if the Distribution Date is on a Saturday or a Sunday or another day on which there is no trading in ILG stock, Starwood may use the first trading date immediately before or immediately after the Distribution Date). Starwood shall use commercially reasonable efforts to inform ILG if it intends to make the 453(d) Election and, if it so intends, to deliver a good faith estimate of the Excess, in each case, no later than December 31, 2016. If Starwood determines to make a Section 453(d) Election, Starwood shall submit to ILG written notice of such determination no later than February 27, 2017, including reasonably satisfactory documentation setting forth the basis for, and calculation of, the Excess, which may be based on good faith estimates, and ILG shall provide any objections to such calculation within twenty (20) days of receipt thereof. If ILG does not provide any objections within such twenty (20) day period, ILG shall be deemed to consent to the Section 453(d) Election. The Parties shall negotiate in good faith to resolve all disputed issues. Any disputes that the Parties are unable to resolve shall be resolved by the Accounting Firm pursuant to Section 8.01. Without duplication of any payment made pursuant to Section 4.06(b), Vistana shall make payments to Starwood in amounts equal to any Tax Benefit actually realized by Vistana or any member of its Tax Group as a result of the Section 453(d) Election for any Tax period after the Effective Time within thirty (30) days of the date that Vistana or any member of its Tax Group actually receives such Tax Benefit. For purposes of this Section 4.08, the term Tax Benefit shall include Tax benefits attributable to the acceleration of gain and income resulting from the Section 453(d) Election, and the amount of such Tax Benefit shall be the amount by which (i) the Vistana Tax Group’s actual Tax liability is

less than (ii) the Tax liability the Vistana Tax Group would have incurred had the Section 453(d) Election not been made. The Parties agree to negotiate in good faith to have Vistana make a single payment to Starwood in lieu of the payments otherwise required under this Section 4.08. If a Tax Benefit actually realized by Vistana or any member of its Tax Group in respect of which a payment has been made pursuant to this Section 4.08 is subsequently reduced as a result of a Tax Proceeding, then Starwood shall return any such amounts previously paid to Starwood by Vistana in respect of such Tax Benefit to the extent of such reduction.

Section 4.09 Tax Benefit Determinations. Notwithstanding anything herein to the contrary, if and to the extent a Party owns, directly or indirectly, less than 100% of the equity of any entity and as a result of such less-than-100% ownership interest in the entity such entity is not a member of the Party’s Tax Group, then the amount of the Tax Benefit payment under Article IV shall be appropriately adjusted to take into account the percentage ownership (based on value) of any such entity, and shall be determined and due and owing even if such entity is not a member of the Tax Group of a Party.

Section 4.10 Supporting Documentation. If a Party seeks any payment from the other Party pursuant to Article IV, the requesting Party and the other Party shall each furnish to each other reasonably satisfactory documentation setting forth the basis for, and the calculation of, the amount of such payment obligation. If there is disagreement between the Parties concerning the determination of the amount of the payment obligation set forth therein, any disputes shall be resolved by the Accounting Firm in accordance with Section 8.1.

Section 4.11 Mitigation Efforts. In connection with a Tax Proceeding, upon the written request from a Party, Starwood, Vistana and ILG shall cooperate (and shall cause their Subsidiaries to cooperate) with the requesting party, at the requesting party’s expense (including indemnification for incremental Taxes resulting from any mitigation actions described below), to cooperate and undertake other actions to mitigate any potential adverse consequences attributable to an adverse determination with respect to the proposed, asserted or assessed adjustment or deficiency, including the filing of Tax elections or the submission of ruling requests to any Taxing Authority. In the event that the above mitigation actions involve the filing of any other Tax election in lieu of the Section 336(e) Election, the principles and methodologies of Section 4.06 shall apply to any such other Tax election.

The failure of the Indemnified Party to notify the Indemnifying Party of the commencement of any such Tax Proceeding within such ten (10)

TAX-FREE STATUS OF THE DISTRIBUTION

Section 6.01 Representations and Warranties.

(a) Vistana. Vistana hereby represents and warrants or covenants and agrees, as appropriate, that the facts presented and the representations made in the Tax Materials, to the extent they both (i) are descriptive of the Vistana Group (including the business purposes for the Distribution described in the Tax Materials to the extent that they relate to the Vistana Group and the plans, proposals, intentions and policies of the Vistana Group after the Effective

Time), and (ii) relate to the actions or non-actions of the Vistana Group to be taken (or not taken, as the case may be) after the Effective Time, are, or will be from the time presented or made through and including the Effective Time (and thereafter as relevant) true, correct and complete in all respects. ILG hereby represents and warrants or covenants and agrees, as appropriate, that the facts presented and the representations made in the Tax Materials, with the consent of ILG, to the extent descriptive of the ILG Group at any time (including the plans, proposals, intentions and policies of the ILG Group at any time) are, or will be from the time presented or made through and including the Effective Time (and thereafter as relevant), true, correct and complete in all respects.

(b) Starwood. Starwood hereby represents and warrants or covenants and agrees, as appropriate, that (i) it has, to the extent available, delivered or will deliver complete and accurate copies of the Tax Materials to Vistana and ILG and (ii) the facts presented and the representations made therein, to the extent descriptive of (A) the Starwood Group at any time or (B) the Vistana Group at any time at or prior to the Effective Time (including, in each case, (x) the business purposes for the Distribution described in the Tax Materials to the extent that they relate to the Starwood Group at any time or the Vistana Group at any time at or prior to the Effective Time, and (y) the plans, proposals, intentions and policies of the Starwood Group at any time or the Vistana Group at any time at or prior to the Effective Time), are, or will be from the time presented or made through and including the Effective Time (and thereafter as relevant) true, correct and complete in all respects.

(c) No Contrary Plan. Each of Starwood and Vistana represents and warrants that neither it, nor any of its Subsidiaries, has any plan or intent to take any action which is inconsistent with any statements or representations made in the Tax Materials.

Section 6.02 Restrictions Relating to the Distribution.

(a) General. Vistana shall not, and shall not permit, any Vistana Entity to take or fail to take, as applicable, any action that constitutes a Vistana Disqualifying Action.

(b) Restrictions. Prior to the first day following the second anniversary of the Distribution (the “Restriction Period”), Vistana:

(i) shall continue and cause to be continued the active conduct of the Vistana Business (as defined in Section 355(b)(2) of the Code), taking into account Section 355(b)(3) of the Code;

(ii) shall not dissolve or liquidate itself or any Vistana Entity (including any action that is a liquidation for federal Income Tax purposes);

(iii) shall not and shall not permit any Vistana Entity to (1) enter into any Proposed Acquisition Transaction or, to the extent Vistana has the right to prohibit any Proposed Acquisition Transaction, permit any Proposed

Acquisition Transaction to occur, (2) redeem or otherwise repurchase (directly or through a Subsidiary) any stock, or rights to acquire stock, other than repurchases satisfying the requirements of Section 4.05(1)(b) of Revenue Procedure 96-30, 1996-1 C.B. 696 (as in effect prior to the release of Revenue Procedure 2003-48, 2003-2 C.B. 86), (3) amend its certificate of incorporation (or other organizational documents), or take any other action, whether through a stockholder vote or otherwise, affecting the relative voting rights of its capital stock (including through the conversion of any capital stock into another class of capital stock), (4) merge or consolidate with any other Person (other than pursuant to the Merger) or (5) take any other action or actions (including any action or transaction that would be reasonably likely to be inconsistent with, or cause to be untrue, any information, statement, representation, undertaking or covenant made in the Tax Materials) which in the aggregate (and taking into account the Merger and any other transactions described in this Section 6.02(b)(iii)) would, when combined with any other direct or indirect changes in ownership of Vistana capital stock pertinent for purposes of Section 355(e) of the Code (including the Merger), have the effect of causing or permitting one or more Persons (whether or not acting in concert) to acquire directly or indirectly stock representing a Fifty-Percent or Greater Interest in Vistana or would reasonably be expected to result in a failure to preserve the Intended Tax Treatment; and

(iv) shall not, and shall not permit any member of the Vistana Group, to sell, transfer, or otherwise dispose of or agree to, sell, transfer or otherwise dispose (including in any transaction treated for federal Income Tax purposes as a sale, transfer or disposition) of assets (including, any shares of capital stock of a Subsidiary) that, in the aggregate, constitute more than twenty-five percent (25%) of the consolidated gross assets of Vistana or the Vistana Group. The foregoing sentence shall not apply to (1) sales, transfers, or dispositions of assets in the Ordinary Course of Business, (2) any cash paid to acquire assets from an unrelated Person in an arm’s-length transaction, (3) any assets transferred to a Person that is disregarded as an entity separate from the transferor for federal Income Tax purposes or (4) any mandatory or optional repayment (or pre-payment) of any indebtedness of Vistana or any member of the Vistana Group. The percentages of gross assets or consolidated gross assets of Vistana or the Vistana Group, as the case may be, sold, transferred, or otherwise disposed of, shall be based on the fair market value of the gross assets of Vistana and the members of the Vistana Group as of the Distribution Date. For purposes of this Section 6.02(b)(iv), a merger of Vistana or one of its Subsidiaries with and into any Person that is not a wholly owned Subsidiary of Vistana or ILG shall constitute a disposition of all of the assets of Vistana or such Subsidiary.

(c) Notwithstanding the restrictions imposed by Section 6.02(b), during the Restriction Period, Vistana may proceed with any of the actions or transactions described therein, if (i) Vistana shall first have requested Starwood to obtain a ruling in accordance with Section 6.03(a) to the effect that such action or transaction will not affect the Intended Tax

Treatment and Starwood shall have received such a ruling in form and substance reasonably satisfactory to it, (ii) Vistana shall have provided to Starwood an Unqualified Tax Opinion in form and substance reasonably satisfactory to Starwood, or (iii) Starwood shall have waived in writing the requirement to obtain such ruling or opinion. For the avoidance of doubt, the presence of a ruling, an Unqualified Tax Opinion or a waiver from Starwood shall not relieve Vistana from indemnification obligations otherwise present under Article III of this Agreement. In determining whether a ruling or opinion is satisfactory, Starwood may consider, among other factors, the appropriateness of any underlying assumptions, representations or covenants used as a basis for the ruling or opinion and the views on the substantive merits.

(d) Tax Reporting. Subject to Section 4.06, each of Starwood, Vistana and ILG covenants and agrees that it will not take, and will cause its respective Subsidiaries to refrain from taking, any position on any Tax Return that is inconsistent with the Intended Tax Treatment.

(e) For the avoidance of the doubt, notwithstanding the restrictions set forth in this Section 6.02, (i) Vistana shall be permitted to enter into the Merger and (ii) Vistana may adopt or modify a shareholder rights plan (and issue stock in accordance therewith) that is described in or similar to the shareholder rights plan described in Revenue Ruling 90-11, 1990-1 C.B. 10.

Section 6.03 Procedures Regarding Opinions and Rulings.

(a) If Vistana notifies Starwood that it desires to take one of the actions described in Section 6.02(b) (a “Notified Action”), Starwood shall cooperate with Vistana and use its reasonable best efforts to seek to obtain a ruling from the IRS or an Unqualified Tax Opinion for the purpose of permitting Vistana to take the Notified Action unless Starwood shall have waived the requirement to obtain such ruling or opinion. If such a ruling is to be sought, Starwood shall apply for such ruling and Starwood and Vistana shall jointly control the process of obtaining such ruling. In no event shall Starwood be required to file any ruling request under this Section 6.03(a) unless Vistana represents that (i) it has read such ruling request, (ii) agrees to all representations contained in such ruling request and (iii) all information and representations, if any, relating to any member of the Vistana Group, contained in such ruling request documents are (subject to any qualifications therein) true, correct and complete. Vistana shall reimburse Starwood for all reasonable costs and expenses incurred by the Starwood Group in obtaining or seeking to obtain a ruling or Unqualified Tax Opinion requested by Vistana within ten (10) days after receiving an invoice from Starwood therefor.

(b) Starwood shall have the right to obtain a ruling or an Unqualified Tax Opinion at any time in its sole and absolute discretion. If Starwood determines to obtain such ruling or opinion, Vistana shall (and shall cause each Vistana Entity to) cooperate with Starwood and take any and all actions reasonably requested by Starwood in connection with obtaining such ruling or opinion (including by making any representation or reasonable covenant or providing any materials requested by the IRS or the law firm issuing such opinion); provided, that Vistana shall not be required to make (or cause a Vistana Entity to make) any representation

or covenant that is untrue or inconsistent with historical facts, or as to future matters or events over which it has no control. In connection with obtaining such ruling, Starwood shall apply for such ruling and shall have sole and exclusive control over the process of obtaining such ruling. Starwood shall reimburse Vistana for all reasonable costs and expenses incurred by the Vistana Group in cooperating with Starwood’s efforts to obtain a ruling or Unqualified Tax Opinion within ten (10) days after receiving an invoice from Vistana therefor.

(c) Except as provided in Sections 6.03(a) and (b), following the Effective Time, neither Vistana nor any Vistana Subsidiary shall seek any guidance from, initiate any communication with, the IRS or any other Taxing Authority (whether written, verbal or otherwise) at any time concerning the Contribution, the Distribution or the Restructuring (including the impact of any transaction on the Contribution, the Distribution or the Restructuring) without the prior approval of Starwood (such approval not to be unreasonably withheld, conditioned or delayed).

ARTICLE VII

COOPERATION

Section 7.01 General Cooperation.

(a) The Parties shall each cooperate fully (and each shall cause its respective Subsidiaries to cooperate fully) with all reasonable requests in writing (“Information Request”) from another Party hereto, or from an agent, representative or advisor to such Party, in connection with the preparation and filing of Tax Returns, claims for Refunds, Tax Proceedings, and calculations of amounts required to be paid pursuant to this Agreement, in each case, related or attributable to or arising in connection with Taxes of any of the Parties or their respective Subsidiaries covered by this Agreement and the establishment of any reserve required in connection with any financial reporting (a “Tax Matter”). Such cooperation shall include the provision of any information reasonably necessary or helpful in connection with a Tax Matter (“Information”) and shall include, without limitation:

(i) the provision of any Tax Returns, other than any Starwood Consolidated Return, of the Parties and their respective Subsidiaries, books, records (including information regarding ownership and Tax basis of property), documentation and other information relating to such Tax Returns, including accompanying schedules, related work papers, and documents relating to rulings or other determinations by Taxing Authorities (or, in the case of any Mixed Business Income Tax Return, to the extent practicable, the portion of such Tax Return that relates to Taxes for which Vistana or ILG is responsible pursuant to this Agreement);

(iv) the use of the Party’s reasonable best efforts to obtain any Tax Returns (including accompanying schedules, related work papers, and documents) (other than any Starwood Consolidated Return), documents, books, records or other information in connection with the filing of any Tax Returns of any of the Parties or their Subsidiaries (or, in the case of any Mixed Business Income Tax Return, to the extent practicable, the portion of such Tax Return, documents, books, records or other information that relates to Taxes for which Vistana or ILG is responsible pursuant to this Agreement); and

(v) Each Party shall make its employees, advisors, and facilities available on a reasonable and mutually convenient basis in connection with the foregoing matters.

(b) Notwithstanding anything in this Agreement to the contrary, neither Party shall be required to provide the other Party or any of such other Party’s Subsidiaries access to or copies of information, documents or personnel if such action could reasonably be expected to result in the waiver of any Privilege. In the event that either Party determines that the provision of any information or documents to the other Party or any of such other Party’s Subsidiaries could be commercially detrimental, violate any law or agreement or waive any Privilege, the Parties shall use commercially reasonable efforts to permit compliance with its obligations hereunder in a manner that avoids any such harm or consequence.

(c) The Parties shall perform all actions required or permitted under this Agreement in good faith. If one Party requests the cooperation of the other Party pursuant to this Section 7.01 or any other provision of this Agreement, except as otherwise expressly provided in this Agreement, the requesting Party shall reimburse such other Party for all reasonable out-of-pocket costs and expenses incurred by such other Party in complying with the requesting Party’s request.

Section 7.02 Retention of Records. Starwood, Vistana and ILG shall retain or cause to be retained all Tax Returns, schedules and work papers, and all material records or other documents relating thereto in their possession, in each case that relate to a Pre-Closing Period, until the later of the six-year anniversary of the filing of the relevant Tax Return or, upon the written request of the other Party, for a reasonable time thereafter (the “Retention Date”). Upon the expiration of the Retention Period, the foregoing information may be destroyed or disposed of by the Party retaining such documentation or other information unless the other Party otherwise requests in writing before the expiration of the Retention Period. In such case, the Party retaining such documentation or other information shall deliver such

materials to the other Party or continue to retain such materials, in either case at the expense of such other Party.

ARTICLE VIII

MISCELLANEOUS

Section 8.01 Dispute Resolution. In the event of any dispute between the Parties as to any matter covered by this Agreement, the Parties shall appoint a nationally recognized independent public accounting firm (the “Accounting Firm”) to resolve such dispute. In this regard, the Accounting Firm shall make determinations with respect to the disputed items based solely on representations made by Starwood, Vistana and ILG and their respective representatives, and not by independent review, and shall function only as an expert and not as an arbitrator and shall be required to make a determination in favor of one Party only. The Parties shall require the Accounting Firm to resolve all disputes no later than thirty (30) days after the submission of such dispute to the Accounting Firm, but in no event later than the Due Date for the payment of Taxes or the filing of the applicable Tax Return, if applicable, and agree that all decisions by the Accounting Firm with respect thereto shall be final and conclusive and binding on the Parties. The Accounting Firm shall resolve all disputes in a manner consistent with this Agreement and, to the extent not inconsistent with this Agreement, in a manner consistent with the Past Practices of Starwood and its Subsidiaries, except as otherwise required by applicable Law. The Parties shall require the Accounting Firm to render all determinations in writing and to set forth, in reasonable detail, the basis for such determination. The fees and expenses of the Accounting Firm shall be borne equally by the Parties.

Section 8.02 Interest on Late Payments. With respect to any payment between the Parties pursuant to this Agreement not made by the due date set forth in this Agreement for such payment, the outstanding amount will accrue interest at a rate per annum equal to the prime rate published in the Wall Street Journal for the relevant period.

Section 8.03 Survival of Covenants. Except as otherwise contemplated by this Agreement, all covenants and agreements of the Parties contained in this Agreement shall survive the Effective Time and remain in full force and effect in accordance with their applicable terms.

Section 8.04 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 without limitation any successor of Starwood, Vistana or ILG 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. As of the Effective Time, this Agreement shall be binding on ILG and ILG shall be subject to the obligations and restrictions imposed on Vistana and the ILG Subsidiary Buyer hereunder, including, without limitation, with respect to the restrictions imposed on Vistana hereunder, including, without limitation, with respect to the indemnification obligations of Vistana and the ILG Subsidiary Buyer under Section 3.02 and the restrictions imposed on Vistana under Section 6.02, and for the avoidance of doubt any

references to Vistana capital stock shall mean both Vistana’s capital stock and, as of and after the Effective Time, ILG’s capital stock and any restrictions applicable to Vistana shall apply to ILG mutatis mutandis.

Section 8.05 Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced under any Law or as a matter of public policy, all other conditions and provisions of this Agreement shall remain in full force and effect. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the Parties to this Agreement shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible in a mutually acceptable manner.

Section 8.06 Entire Agreement. Except as otherwise expressly provided in this Agreement, this Agreement constitutes the entire agreement of the Parties hereto with respect to the subject matter of this Agreement and supersedes all prior agreements and undertakings, both written and oral, between or on behalf of the Parties hereto with respect to the subject matter of this Agreement.

Section 8.07 Assignment; No Third-Party Beneficiaries. This Agreement shall not be assigned by any Party without the prior written consent of the other Parties hereto, except that each Party may assign (a) any or all of its rights and obligations under this Agreement to any of its Subsidiaries and (b) any or all of its rights and obligations under this Agreement in connection with a sale or disposition of any of its assets or entities or lines of business; provided, however, that, in each case, no such assignment shall release such Party from any liability or obligation under this Agreement. Except as provided in Article III with respect to indemnified Parties, this Agreement is for the sole benefit of the Parties to this Agreement and their respective Subsidiaries and their permitted successors and assigns and nothing in this Agreement, express or implied, is intended to or shall confer upon any other Person any legal or equitable right, benefit or remedy of any nature whatsoever under or by reason of this Agreement.

Section 8.08 Specific Performance. In the event of any actual or threatened default in, or breach of, any of the terms, conditions and provisions of this Agreement, the Party who is or is to be thereby aggrieved shall have the right to specific performance and injunctive or other equitable relief of its rights under this Agreement, in addition to any and all other rights and remedies at law or in equity, and all such rights and remedies shall be cumulative. The Parties agree that the remedies at law for any breach or threatened breach, including monetary damages, may be inadequate compensation for any loss and that any defense in any action for specific performance that a remedy at law would be adequate is waived. Any requirements for the securing or posting of any bond with such remedy are waived by the Parties to this Agreement.

Section 8.09 Amendment. No provision of this Agreement may be amended or modified except by a written instrument signed by the Parties to this Agreement. No waiver by any Party of any provision of this Agreement shall be effective unless explicitly set

forth in writing and executed by the Party so waiving. The waiver by any Party of a breach of any provision of this Agreement shall not operate or be construed as a waiver of any other subsequent breach.

Section 8.11 Counterparts. This Agreement may be executed in one or more 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.
