(iv) shall not, and shall not permit any WPG Entity (or members of their respective SAGs) 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 Equity Securities of a Subsidiary) that, in the aggregate, constitute more than thirty percent (30%) of the gross assets of WPG or WPG TRS or more than thirty percent (30%) of the consolidated gross assets of WPG, the members of its SAG and WPG LP, or WPG TRS and the members of its SAG, respectively. The foregoing sentence shall not apply to (A) sales, transfers, or dispositions of assets in the Ordinary Course of Business, (B) any cash paid to acquire assets from an unrelated Person in an arm’s-length transaction, (C) any assets transferred to a Person that is disregarded as an entity separate from the transferor for U.S. federal Income Tax purposes or (D) any mandatory or optional repayment (or pre-payment) of any indebtedness of WPG or WPG TRS (or any member of their respective SAGs or WPG LP). The percentages of gross assets or consolidated gross assets of WPG or WPG, the members of its SAG and WPG LP, or WPG TRS or WPG TRS and the members of its SAG, as the case may be, sold, transferred, or otherwise disposed of, shall be based on the fair market value of the gross assets of such entity or entities as of the Closing Date. For purposes of this Section 8.02(c)(iv), a merger of WPG, WPG LP or WPG TRS (or a member of its SAG) with and into any Person shall constitute a disposition of all of the assets of such entity or such member.

(d) Notwithstanding the restrictions imposed by Section 8.02(c), during the Restriction Period, WPG may proceed with any of the actions or transactions described in Section 8.02(c), if (x) such action or transaction is not described in Section 8.02(a) or Section 8.02(b) and (y) prior to entering into any agreement contemplating such action or transaction, and prior to taking or consummating any such action or transaction, (i) WPG shall first have requested SPG to obtain a private letter ruling from the IRS (and any other relevant Taxing Authority) (a “Post-Distribution Ruling”) in accordance with Section 8.03 of this Agreement to the effect that such action or transaction will not affect the Tax-Free Status of any of the Transactions and SPG shall have received such Post-Distribution Ruling in form and substance satisfactory to SPG in its sole and absolute discretion, (ii) WPG shall have provided SPG with an Unqualified Tax Opinion in form and substance satisfactory to SPG in its sole and absolute discretion, or (iii) SPG shall have waived in writing (a “Waiver”) the requirement to obtain such Post-Distribution Ruling or Unqualified Tax Opinion. In determining whether a Post-Distribution Ruling or Unqualified Tax Opinion is satisfactory, SPG shall exercise its discretion in good faith and may consider, among other factors, the appropriateness of any underlying assumptions or representations used as a basis for the Post-Distribution Ruling or Unqualified Tax Opinion and the views on the substantive merits. For the avoidance of doubt, WPG LP shall not be relieved of any indemnification obligation pursuant to Article V or otherwise under this

Agreement as a result of having satisfied the requirements of clause (i), (ii) or (iii) of this Section 8.02(d).

(e) Certain Issuances of Capital Stock. If WPG proposes to enter into any Section 8.02(e) Acquisition Transaction or, to the extent WPG has the right to prohibit any Section 8.02(e) Acquisition Transaction, proposes to permit any Section 8.02(e) Acquisition Transaction to occur, in each case, during the Restriction Period, WPG, shall provide SPG, no later than ten (10) days following the signing of any written agreement with respect to any Section 8.02(e) Acquisition Transaction, with a written description of such transaction (including the type and amount of WPG Equity Securities to be issued in such transaction).

(f) Tax Reporting. Each of WPG and SPG covenants and agrees that it will not take, and will cause its respective Affiliates not to take, any position on any Tax Return that is inconsistent with the Tax-Free Status of the Transactions.

Section 8.03. Procedures Regarding Post-Distribution Rulings and Unqualified Tax Opinions.

(a) Notification. If WPG determines that it desires to take one of the actions described in Sections 8.02(c) (a “Notified Action”), WPG shall promptly notify SPG of this fact in writing.

(b) Post-Distribution Rulings or Unqualified Tax Opinions at WPG’s Request. Upon the reasonable request of WPG pursuant to Section 8.03(a), SPG shall cooperate with WPG and use its commercially reasonable efforts to seek to obtain, as expeditiously as possible, a Post-Distribution Ruling or an Unqualified Tax Opinion for the purpose of permitting WPG to take the Notified Action unless SPG shall have waived the requirement to obtain such Post-Distribution Ruling or Unqualified Tax Option in writing pursuant to Section 8.02(d). Notwithstanding the foregoing, in no event shall SPG be required to file or cooperate in the filing of any ruling request for a Post-Distribution Ruling under this Section 8.03(b) unless SPG represents that (i) it has read such ruling request, and (ii) all statements, information and representations relating to any member of the WPG Group contained in such ruling request are (subject to any qualifications therein) true, correct and complete. WPG LP shall reimburse SPG LP for all reasonable costs and expenses incurred by the SPG Group in obtaining a Post-Distribution Ruling or Unqualified Tax Opinion requested by SPG within ten (10) days after receiving an invoice from SPG therefor.

(c) Post-Distribution Rulings or Unqualified Tax Opinions at SPG’s Request. SPG shall have the right to obtain a Post-Distribution Ruling or a tax opinion at any time in its sole and absolute discretion. If SPG determines to obtain a Post-Distribution Ruling or a tax opinion, WPG shall (and shall cause each WPG Entity to) cooperate with SPG and take any and all actions reasonably requested by SPG in connection with obtaining such Post-Distribution Ruling or tax opinion (including, without limitation, by making any representation or covenant or providing any information, documents and materials requested by the IRS, any other relevant Taxing Authority or the Tax Counsel issuing such opinion); provided, that WPG shall not be required to make (or cause a WPG Entity to make) any representation or covenant that is inconsistent with historical facts or as to future matters or events over which it has no control.

SPG and WPG shall each bear its own costs and expenses in obtaining a Post-Distribution Ruling or tax opinion requested by SPG.

(d) All Post-Distribution Rulings. SPG shall have sole and exclusive control over the process of obtaining any Post-Distribution Ruling, and only SPG shall be permitted to apply for a Post-Distribution Ruling. In connection with obtaining a Post-Distribution Ruling, (i) SPG shall keep WPG informed in a timely manner of all material actions taken or proposed to be taken by SPG in connection therewith; (ii) SPG shall (1) reasonably in advance of the submission of any request for a Post-Distribution Ruling provide WPG with a draft copy thereof; (2) reasonably consider WPG’s comments on such draft copy; and (3) provide WPG with a final copy; and (iii) provide WPG with notice reasonably in advance of, and WPG shall have the right to attend, any formally scheduled meetings with the IRS (subject to the approval of the IRS) that relate to such Post-Distribution Ruling. Neither WPG nor any WPG Entity shall seek any guidance from the IRS or any other Taxing Authority (whether written, verbal or otherwise) at any time concerning the Restructuring or the Distribution (including the impact of any transaction on the Restructuring or the Distribution).

Section 8.04. Section 336(e) Election. If SPG determines, in its sole discretion, that a protective election under Section 336(e) of the Code (a “Section 336(e) Election”) shall be made with respect to the TRS Distribution or the Distribution, WPG shall (or shall cause the relevant WPG Entity to) join with SPG or the relevant SPG Entity in the making of such election and shall take any action reasonably requested by SPG or that is otherwise necessary to give effect to such election (including making any other related election). If a Section 336(e) Election is made with respect to the TRS Distribution or the Distribution, then this Agreement shall be amended in such a manner as is determined by SPG in good faith to take into account such Section 336(e) Election.

ARTICLE IX
RPT CONTRIBUTION

Section 9.01. Prohibited Actions. For a period of five (5) years following the RPT Contribution, WPG and WPG LP shall not (and shall not permit any of their respective Affiliates to) take any action or fail to take any action (including, without limitation, any sale, disposition, contribution or other transfer of any of the RPT Contributed Properties or any interest therein, any reduction in the amount of Liabilities to which any of the RPT Contributed Properties are subject and any distribution of RPT Contributed Properties or any other properties or assets) that would result in RPT, any of its Affiliates or any member of the SPG Group recognizing any RPT Built-In Gain or any RPT Section 752 Gain for U.S. federal income tax purposes.

Section 9.02. Section 704(c) Allocations. WPG LP and any other entity in which WPG LP has a direct or indirect interest shall use the “traditional method” (without “curative allocations”) under Treasury Regulations Section 1.704-3(b) for purposes of making allocations under Section 704(c) of the Code with respect to the RPT Contributed Properties.

Section 9.03. Damages. In the event of a breach of any of the covenants set forth in Section 9.01 or Section 9.02, as applicable, (a) for purposes of Section 5.02(ii), RPT (or other relevant member of the SPG Group) shall be deemed to have incurred Taxes as a result of such

breach in an amount equal to the product of (i) in the case of a breach of the covenants set forth in Section 9.01, the RPT Built-In Gain or the RPT Section 752 Gain, as applicable, and, in the case of a breach of the covenants set forth in Section 9.02, the additional amount of income or gain allocated under Section 704(c), and (ii) forty percent (40%) and (b) for purposes of Section 5.03(b), RPT (or other relevant member of the SPG Group) shall be deemed to have paid Taxes on any indemnification payment received on account of such breach that is required to be included in income (and not to have distributed any amount under Section 857(a) of the Code as a result therefrom) at a rate of forty percent (40%).

Section 9.04. Exclusive Remedy. Notwithstanding anything to the contrary in this Agreement (including Section 11.08), the sole and exclusive remedy with respect to any breach of the covenants set forth in Section 9.01 or Section 9.02 shall be the receipt of indemnification payments pursuant to Article V (as determined pursuant to Section 9.03), and in no event shall RPT or any member of the SPG Group have any right to specific performance with respect to any breach or threatened breach of any of the covenants set forth in Section 9.01 or Section 9.02.

Section 9.05. Notice. WPG and WPG LP shall notify SPG in writing at least sixty (60) days prior to taking any action (or failing to take any action) that would result in a breach of the covenants set forth in Section 9.01.

(a) In the event of any dispute between the Parties as to any matter covered by this Agreement, the Parties shall agree as to whether such dispute shall be governed by the procedures set forth in Section 11.01(b) of this Agreement or in Article VII of the Separation and Distribution Agreement. If the Parties cannot agree within thirty (30) days from the time such dispute arises as to which procedure will govern such dispute, such disagreement shall be resolved pursuant to Article VII of the Separation and Distribution Agreement.

(b) With respect to any dispute governed by this Section 11.01(b), the Parties shall appoint a nationally recognized “Big Four” independent public accounting firm (other than the current auditing firm of SPG or WPG) (the “Accounting Firm”) to resolve such dispute. The Parties shall cooperate in good faith in jointly selecting the Accounting Firm. If the Parties cannot agree on a nationally recognized firm within thirty (30) days from the time such dispute arises, the Parties shall appoint Deloitte LLP to be the Accounting Firm. In this regard, the Accounting Firm shall make determinations with respect to the disputed items based solely on representations made by SPG and WPG 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 fifteen (15) 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 SPG and the members of the SPG Group, 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 paid by the non-prevailing Party.

Section 11.02. Tax Sharing Agreements. All Tax sharing, indemnification and similar agreements, written or unwritten, as between SPG or a SPG Entity, on the one hand, and WPG or a WPG Entity, on the other hand (other than this Agreement, the Separation and Distribution Agreement, any other Ancillary Agreement and any agreement entered into after the Distribution), shall be or shall have been terminated no later than the Effective Time and, after the Effective Time, none of SPG, any SPG Entity, WPG or any WPG Entity shall have any further rights or obligations under any such Tax sharing, indemnification or similar agreement.

Section 11.03. 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 rate in effect for underpayments under Section 6621 of the Code from such due date to and including the earlier of the ninetieth (90th) day or the payment date and thereafter will accrue interest at a rate per annum equal to Prime Rate plus 2%.

Section 11.04. 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; provided, however, that the representations and warranties and all indemnification for Taxes shall survive until sixty (60) days following the expiration of the applicable statute of limitations (taking into account all extensions thereof), if any, for assessment of the Tax that gave rise to the indemnification; provided, further, that, in the event that notice for indemnification has been given within the applicable survival period, such indemnification shall survive until such time as such claim is finally resolved.

Section 11.05. 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 11.06. 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 11.07. No Third-Party Beneficiaries. Except as provided in Article V 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 11.08. Specific Performance. Subject to Section 9.04, 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. Subject to Section 9.04, 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 11.09. 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 11.11. 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

Section 11.14. Governing Law. This Agreement (and any claims or disputes arising out of or related hereto or to the transactions contemplated hereby or to the inducement of any Party to enter herein, whether for breach of contract, tortious conduct or otherwise and whether predicated on common law, statute or otherwise) shall be governed by and construed and interpreted in accordance with the Laws of the State of Indiana, irrespective of the choice of Laws principles of the State of Indiana, including all matters of validity, construction, effect, enforceability, performance and remedies.

Section 11.15. Assignability. This Agreement shall be binding upon and inure to the benefit of the Parties and their respective successors and permitted assigns. Neither Party may assign its rights or delegate its obligations under this Agreement without the express prior written consent of the other Party hereto; provided, however, that each Party may assign all of its rights and obligations under this Agreement to any of its Subsidiaries; provided, further, that no such assignment shall release the assigning Party from any of its liabilities or obligations under this Agreement. Notwithstanding the foregoing, no consent for assignment shall be required for the assignment of a Party’s rights and obligations under this Agreement, the Separation and Distribution Agreement and all other Ancillary Agreements in whole (i.e., the assignment of a party’s rights and obligations under this Agreement and all Ancillary Agreements all at the same time) in connection with a change of control of a Party so long as the resulting, surviving or transferee Person assumes all the obligations of the relevant Party by operation of Law or pursuant to an agreement in form and substance reasonably satisfactory to the other Party. Nothing herein is intended to, or shall be construed to, prohibit either Party or any of its Subsidiaries from being party to or undertaking a transaction that would result in a change of control.
