WHEREAS, the Partnership and the REIT desire for the REIT to undertake an initial public offering, all of the net proceeds of which will be contributed by the REIT to the Partnership and which will result in the REIT becoming the general partner of the Partnership (the “IPO Transaction”);

WHEREAS, in connection with the IPO Transaction, the parties desire to enter into this Agreement regarding certain tax matters related to Protected Properties and the tax positions of the Protected Partners, including their agreement regarding amounts that may be payable by the Partnership to the Protected Partners as a result of certain actions being taken by the Partnership regarding the disposition, directly or indirectly, of interests in the Protected Properties and certain debt obligations of the Partnership and its subsidiaries.

For the avoidance of doubt, if any Protected Property is transferred to another entity in a transaction in which gain or loss is not recognized in full, and if the acquiring entity’s disposition of such Protected Property would cause the Protected Partners to recognize gain or loss as a result thereof, such Protected Property (including any interest in such entity acquired directly or indirectly by the Partnership in connection therewith) shall still be subject to this Agreement.

ARTICLE 2

DISPOSITIONS OF

PROTECTED PROPERTIES

2.1 Disposition of Protected Properties. The REIT and the Partnership agree for the benefit of each Protected Partner, for the term of the Tax Protection Period, that in the event that the Partnership, directly or indirectly sells, exchanges, transfers, or otherwise disposes of a Protected Property or any interest therein (without regard to whether such disposition is voluntary or involuntary) in a transaction that would cause a Protected Partner to recognize any Protected Gain, the provisions of Article 4 shall apply and the Partnership shall make the payments to the Protected Partners provided for in Article 4.

Without limiting the foregoing, the term “sale, exchange, transfer or disposition” by the Partnership shall be deemed to include, and the rights of the Protected Partners with respect thereto under Article 4 shall extend to:

Without limiting the foregoing, a disposition shall include any transfer, voluntary or involuntary, by the Partnership or a Subsidiary in a foreclosure proceeding, pursuant to a deed in lieu of foreclosure, or in a bankruptcy proceeding.

2.2 Exceptions Where No Gain Recognized. Notwithstanding the restriction set forth in Section 2.1, the Partnership or a Subsidiary may dispose of any Protected Property (or any interest therein), and Article 4 shall not apply with respect thereto, if and to the extent that such disposition qualifies as a like-kind exchange under Section 1031 of the Code, or an involuntary conversion under Section 1033 of the Code, or other transaction (including, but not limited to, a contribution of property to any entity that qualifies for the non-recognition of gain under Section 721 or Section 351 of the Code, or a merger or consolidation of the Partnership with or into another entity that qualifies for taxation as a “partnership” for federal income tax purposes (a “Successor Partnership”)) that, as to each of the foregoing, does not result (in the year of such disposition or in a later year within the Tax Protection Period) in the recognition of any taxable income or gain to any Protected Partner with respect to any of the Units; provided, however, that:

4

2.3 Merger Transactions. Any merger or consolidation of the Partnership or any Subsidiary, whether or not the Partnership or Subsidiary is the surviving entity in such merger or consolidation, that results in a Protected Partner recognizing part or all of the Protected Gain shall be deemed to be a disposition of the Protected Properties for purposes of Section 2.1, and Article 4 shall fully apply, except as expressly provided in this Section 2.3.

In the event of a merger or consolidation of the Partnership (or any Subsidiary) and a Successor Partnership that does not result in a Protected Partners being required to recognize all of the Protected Gain, the Successor Partnership must have agreed in writing for the benefit of the Protected Partners that all of the restrictions contained in this Agreement shall continue to apply, including but not limited to, those with respect to each Protected Property, in order for such merger or consolidation not to be reconsidered to have resulted in the recognition by the Protected Partners of all of their Protected Gain as a result thereof.

This Section 2.3, Section 2.1 and Article 4 shall not apply to a voluntary, actual disposition by a Protected Partner of Units in connection with a merger or consolidation to which the Partnership or the REIT is a party and in connection with which all of the following requirements are satisfied:

(1) the Protected Partner is offered either:

(A) cash or property treated as cash pursuant to Section 731 of the Code (“Cash Consideration”) or

(B) partnership interests in a partnership that would be treated as the continuing partnership under the principles of Section 708 of the Code and the receipt of such partnership interests would not result in the recognition of gain for federal income tax purposes and which partnership interests have a fair value, per Unit, equal to the greater of (i) the value that the Protected Partner would have received on the date of such merger or consolidation had such Protected Partner chosen to exercise its

5

rights under Section 8.6 of the Partnership Agreement immediately prior to such date or (ii) the amount per share (adjusted to take into account all adjustments that would result in an adjustment to the “Conversion Factor” under the Partnership Agreement) to be paid to the shareholders of the REIT in connection with such merger or consolidation (“Partnership Interest Consideration”);

(2) the Protected Partner has the ability to elect to receive solely Partnership Interest Consideration in exchange for his Units and the continuing partnership has agreed in writing to assume the obligations of the Partnership under this Agreement;

(3) no Protected Gain is recognized by the Partnership as a result of any partner of the Partnership receiving Cash Consideration;

(4) any Successor Partnership in such merger or consolidation shall have complied with the preceding paragraph of this Section 2.3; and

(5) the Protected Partner elects to receive Cash Consideration.

In the event of a voluntary, actual disposition by a Protected Partner of Units in connection with a merger, consolidation or other transaction involving the Partnership that does not comply with the conditions in the prior paragraph, then Section 2.1 and Article 4 shall be considered to apply to such disposition.

In addition, if (1) there is a merger, consolidation or other transaction involving the REIT that results in the shares of the REIT (or any “Successor Entity” to the REIT as that term is used in the Partnership Agreement) not being considered to be traded on the New York Stock Exchange, and (2) there is an actual disposition by a Protected Partner of Units in connection with or immediately prior to such a merger, consolidation or other transaction (including through exercise of the “Redemption Right” provided for in the Partnership Agreement), then Section 2.1 and Article 4 shall be considered to apply to such disposition unless, immediately following such merger, consolidation or other transaction involving the REIT, the Units (or any partnership interests received in exchange therefor) held by the Protected Partner would be considered to have a fair value, per Unit (determined including rights to liquidity comparable to those provided under Section 8.6 of the Partnership Agreement), equal to the amount per share (adjusted to take into account all adjustments that would result in an adjustment to the “Conversion Factor” under the Partnership Agreement) to be paid to the shareholders of the REIT in connection with such merger or consolidation.

2.4 “Extraordinary Transactions”. In the event that there is any “Extraordinary Transaction” (as defined in the Partnership Agreement) with respect to which the general partner of the Partnership exercises its right under Section 8.6.B (iv) of the Partnership Agreement and a Protected Partner recognizes part or all of the Protected Gain as a result of the exercise by the general partner of such rights, there shall be deemed to be a disposition of all of the Protected Properties for purposes of Section 2.1, and Article 4 shall fully apply with respect thereto.

ARTICLE 3

ALLOCATION OF LIABILITIES; GUARANTEE OPPORTUNITY AND DEFICIT RESTORATION OBLIGATIONS

3.1 Minimum Liability Allocation. It is the Partnership’s expectation that at the time of the IPO Transaction and for the foreseeable future thereafter, each Protected Partner will be

6

allocated Non Recourse Liabilities at least equal to the Minimum Liability Amount for such Protected Partner. If at any time after the IPO Transaction and during the Tax Protection Period, the Partnership determines that there is a reasonable possibility that a Protected Partner will not be allocated Non Recourse Liabilities at least equal to the Minimum Liability Amount for such Protected Partner for any reason (including, without limitation, any Non Recourse Liabilities ceasing to be Non Recourse Liabilities because they become subject to a guarantee by the REIT or an affiliate of the REIT), the Partnership shall immediately (and, in any event, not less than 30 days prior to the point in time at which the Protected Partner will cease to be allocated Non Recourse Liabilities at least equal to its Minimum Liability Amount (including by reason of a guarantee by the REIT or an affiliate of the REIT becoming applicable to any Non Recourse Liability)) offer to each such Protected Partner, at the Protected Partner’s option, the opportunity either (i) to enter into Qualified Guarantees of Qualified Guarantee Indebtedness or (ii) to enter into a Deficit Restoration Obligation, in such amount or amounts so as to cause the amount of partnership liabilities allocated to such Protected Partner for purposes of Section 752 of the Code to be not less than such Protected Partner’s Minimum Liability Amount and to cause the amount of partnership liabilities with respect to which such Protected Partner will be considered to be “at risk” for purposes of Section 465 of the Code to be not less than such Protected Partner’s Minimum Liability Amount, as provided in this Article 3. In order to minimize the need for Protected Partners to enter into Qualified Guarantees or Deficit Restoration Obligations, the Partnership will use the optional method under Treasury Regulations Section 1.752-3(a)(3) to allocate Nonrecourse Liabilities considered secured by a Protected Property to the Protected Partners to the extent that the “built-in gain” with respect to those properties exceeds the amount of the Nonrecourse Liabilities considered secured by such Protected Property allocated to the Protected Partners under Treasury Regulations Section 1.752-3(a)(2).

3.2 Qualified Guarantee Indebtedness and Qualified Guarantee; Treatment of Qualified Guarantee Indebtedness as Guaranteed Debt. In order for an offer by the Partnership of an opportunity to guarantee indebtedness to satisfy the requirements of this Article 3, (1) the indebtedness to be guaranteed must satisfy all of the conditions set forth in this Section 3.2 (indebtedness satisfying all such conditions is referred to as “Qualified Guarantee Indebtedness”); (2) the guarantee by the Partner Guarantors must be pursuant to a Guarantee Agreement substantially in the form attached hereto as Schedule 3.7 that satisfies the conditions set forth in Sections 3.2(i) and (iii) (a “Qualified Guarantee”); (3) the amount of debt required to be guaranteed by the Partner Guarantor must not exceed the portion of the Guaranteed Amount for which a replacement guarantee is being offered; and (4) the debt to be guaranteed must be considered indebtedness of the Partnership for purposes of determining the adjusted tax basis of the interests of partners in the Partnership in their partnership interests. If, and to the extent that, a Partner Guarantor elects to guarantee Qualified Guarantee Indebtedness pursuant to an offer made in accordance with this Article 3, such indebtedness thereafter shall be considered a Guaranteed Debt and shall be subject to all of this Article 3. The conditions that must be satisfied at all times with respect to any additional or replacement Guaranteed Debt offered pursuant to this Article 3 hereof and the guarantees with respect thereto are as follows:

7

8

The Partnership shall be deemed to satisfy the requirements of Sections 3.2(i), (ii) and (v) above if, in lieu of offering the opportunity to enter into a “bottom dollar guarantee” of indebtedness secured by specific properties, it offers the Protected Partner an opportunity to enter into a “bottom dollar guarantee” (or an indemnity on comparable terms of an existing guarantor) of a general senior unsecured obligation of the Partnership which (A) is recourse, without limitation, to all of the assets of the Partnership, (B) is made by a third party institutional lender with financial covenants that are standard for such a loan, (C) is not in default and (D) either (i) qualifies as Nonrecourse Liability of the Partnership, or (ii) is a liability that is treated as a “recourse” liability under the applicable Treasury Regulations solely because the general partner of the Partnership has liability therefor, either by reason of its status as “general partner” or due to an express guarantee entered into by the general partner; provided, however, that the “bottom guarantee” shall include an indemnification of the general partner with respect thereto sufficient to cause the Protected Partner to be considered to “bear the economic risk of loss,” within the meaning of Treasury Regulation § 1.752-2, with respect to the amount provided for in such “bottom guarantee” without increasing the financial exposure of the Protected Partner above the level that would have resulted had such liability been a Nonrecourse Liability.

3.3 Covenant With Respect to Guaranteed Debt Collateral. The Partnership covenants with the Partner Guarantors with respect to the Guaranteed Debt that (A) it will comply with the requirements set forth in Section 2.2(b) upon any disposition of any collateral for a Guaranteed Debt, whether during or following the Tax Protection Period, and (B) it will not at any time, whether during or following the Tax Protection Period, pledge the collateral with respect to a Guaranteed Debt to secure any other indebtedness (unless such other indebtedness is, by its terms, subordinate in all respects to the Guaranteed Debt for which such collateral is security) or otherwise voluntarily dispose of or reduce the amount of such collateral unless either (i) after giving effect thereto the conditions in Section 3.2 would continue to be satisfied with respect to the Guaranteed Debt and the Guaranteed Debt otherwise would continue to be Qualified Guarantee Indebtedness, or (ii) the Partnership (A) obtains from the lender with respect to the original Guaranteed Debt a full and complete release of any Partner Guarantor unless the Partner Guarantor expressly requests that it not be released, and (B) if the Tax Protection Period has not expired, offers to each Partner Guarantor with respect to such original Guaranteed Debt, not less than 30 days prior to such pledge or disposition, the opportunity, at the option of the Protected Partner, either (1) to enter into a Qualified Guarantee of other Partnership indebtedness that constitutes Qualified Guarantee Indebtedness (with such replacement indebtedness thereafter being considered a Guaranteed Debt and subject to this Article 3) in an amount equal to the amount of such original Guaranteed Debt that was guaranteed by such Partner Guarantor or (2) to enter into a DRO in the amount of the original Guaranteed Debt that was guaranteed by such Partner Guarantor.

3.4 Repayment or Refinancing of Guaranteed Debt. The Partnership shall not, at any time during the Tax Protection Period applicable to a Partner Guarantor, repay or refinance all or any portion of any Guaranteed Debt unless (i) after taking into account such repayment, each Partner Guarantor would be entitled to include in its basis for its Units an amount of Guaranteed Debt equal to its Minimum Liability Amount, or (ii) alternatively, the Partnership, not less than 30 days prior to such repayment or refinancing, offers to the applicable Partner Guarantors the opportunity, at the option of the Protected Partner, either (A) to enter into a Qualified Guarantee with respect to other Qualified Guarantee Indebtedness or (B) to enter into a DRO, in either case in an

9

amount sufficient so that, taking into account such guarantees of such other Qualified Guarantee Indebtedness or DRO, as applicable, each Partner Guarantor who guarantees such other Qualified Guarantee Indebtedness or enters into a DRO in the amount specified by the Partnership would be entitled to include in its adjusted tax basis for its Units debt equal to the Minimum Liability Amount for such Partner Guarantor.

3.5 Limitation on Additional Guarantees With Respect to Debt Secured by Collateral for Guaranteed Debt. The Partnership shall not offer the opportunity or make available to any person or entity other than a Protected Partner a guarantee of any Guaranteed Debt or other debt that is secured, directly or indirectly, by any collateral for Guaranteed Debt unless (i) such debt by its terms is subordinate in all respects to the Guaranteed Debt or, if such other guarantees are of the Guaranteed Debt itself, such guarantees by their terms must be paid in full before the lender can have recourse to the Partner Guarantors (i.e., the first dollar amount of recovery by the applicable lenders must be applied to the Guaranteed Amount); provided that the foregoing shall not apply with respect to additional guarantees of Guaranteed Debt so long as the conditions set forth in Sections 3.2(ii) and (v) would be satisfied immediately after the implementation of such additional guarantee (determined in the case of Section 3.2(ii), based upon the fair market value of the collateral for such Guaranteed Debt at the time the additional guarantee is entered into and adding the amount of such additional guarantee(s) to the sum of the applicable Guaranteed Amounts plus any other preexisting “bottom dollar guarantee” previously permitted pursuant to this Section 3.5 or Sections 3.2(i) and (ii) above, for purposes of making the computation provided for in Section 3.2(ii)), and (ii) such other guarantees do not have the effect of reducing the amount of the Guaranteed Debt that is includible by any Partner Guarantor in its adjusted tax basis for its Units pursuant to Treasury Regulation § 1.752-2.

3.6 Process. Whenever the Partnership is required under this Article 3 to offer to one or more of the Partner Guarantors an opportunity, at the option of the Partner Guarantor, either to guarantee Qualified Guarantee Indebtedness or enter into a DRO, the Partnership shall be considered to have satisfied its obligation under this Article 3 if the other conditions in this Article 3 are satisfied and, not less than thirty (30) days prior to the date that such guarantee would be required to be executed in order to satisfy this Article 3, the Partnership sends by first class mail, return receipt requested, to the last known address of each such Partner Guarantor (as reflected in the records of the Partnership) (i) the Guarantee Agreement or a consent to DRO form, as applicable, to be executed (which in the case of Guarantee Agreement shall be substantially in the form of Schedule 3.7 hereto, with such changes thereto as are necessary to reflect the relevant facts) and (ii) a brief letter setting forth (v) the relevant circumstances (including, as applicable, that the offer is being made pursuant to this Article 3, the circumstances giving rise to the offer, a brief summary of the terms of the Qualified Guarantee Indebtedness to be guaranteed (or, in the case of a DRO, the terms of the Partnership recourse debt), (w) a brief description of the collateral for the Qualified Guarantee Indebtedness, (x) a statement of the amount to be guaranteed (or DRO amount), (y) the address to which the executed Guarantee Agreement (or consent to DRO form) must be sent and the date by which it must be received, and (z) a statement to the effect that, if the Protected Partner fails to execute and return such Guarantee Agreement (or consent to DRO form) within the time period specified, the Partner Guarantor thereafter would lose its rights under this Article 3 with respect to the amount of debt that the Partnership is required to offer to be guaranteed (or that would be subject to the DRO), and depending upon the Partner Guarantor’s circumstances and other circumstances related to the Partnership, the Partner Guarantor could be required to recognize taxable gain as a result thereof, either currently or prior to the expiration of the Tax Protection Period, that otherwise would have been deferred. If a notice is properly sent in accordance with this Section 3.6, the Partnership shall have no responsibility as a result of the failure of a Partner Guarantor either to receive such notice or to respond thereto within the specified time period.

10

3.7 Presumption as to Schedule 3.7. A guarantee in the form of the Guarantee Agreement attached hereto as Schedule 3.7 that is (A) properly executed by the Partner Guarantor and the lender and (B) delivered to the lender shall be conclusively presumed to satisfy the conditions set forth in Section 3.2(i) and to have caused the Guaranteed Debt to be considered allocable to the Guarantor Partner who enters into such Guarantee Agreement pursuant to Treasury Regulation § 1.752-2 and Section 465 of the Code so long as all of the following conditions are met with respect such Guaranteed Debt:

Notwithstanding the foregoing, if, due to a change in tax law after the date hereof, either the Partnership determines or a Protected Partner is advised by counsel, that there is a material risk that such Protected Partner may no longer continue to be allocated such Protected Partner’s Guaranteed Amount of a Guaranteed Debt, such Protected Partner may request a modification of such Guarantee Agreement and the Partnership will use its commercially reasonable efforts to work with the lender with respect to such Guaranteed Debt to have the Guarantee Agreement amended in a manner that will permit such Protected Partner to be allocated such Protected Partner’s Guaranteed Amount with respect to the Guaranteed Debt, or such Protected Partner, at its option shall be offered the opportunity to enter into a DRO, in an amount equal to such Guaranteed Amount so that the amount of Partnership liabilities allocated to such Protected Partner shall not decrease as a result of the change in law. For the avoidance of doubt, each Protected Partner hereby acknowledges and agrees that the Partnership shall not be treated as violating this Article 3 to the extent that, after such a change of tax law, the allocation of Partnership indebtedness for tax purposes to the Protected Partner cannot be achieved due to the unwillingness of such Protected Partner either to provide a guarantee or similar instrument that complies with the new tax law rules (where both such guarantee or similar instrument and the indebtedness being guaranteed

11

is otherwise consistent to the maximum extent permitted by such new tax rules with the provisions of this Article 3) or to enter into a DRO pursuant to Section 3.8; provided, however, that the Partnership’s obligations as set forth in the last sentence of Section 3.1 shall continue to apply. Any cost and expenses incurred as a result of such a change in tax law shall be borne equally by the Partnership on the one hand and the relevant Protected Partner on the other hand.

3.8 Deficit Restoration Obligation. In the event a Protected Partner has elected to enter into a DRO, the Partnership will maintain an amount of indebtedness of the Partnership that would be considered “recourse” indebtedness (taking into account all of the facts and circumstances related to the indebtedness, the Partnership and the General Partner) equal to or greater than the sum of the “DRO Amounts” (as defined in the Partnership Agreement) of all Protected Partners (plus, the DRO Amounts, if any, of other partners in the Partnership). The deficit restoration obligation shall be conclusively presumed to cause the Protected Partner to be allocated an amount of liabilities equal to the DRO Amount of such Protected Partner for purposes of Sections 465 and 752 of the Code, provided that (1) the Partnership maintains an amount of debt that is considered “recourse” indebtedness (determined for purposes of Section 752 of the Code and taking into account all of the facts and circumstances related to the indebtedness, the Partnership and the General Partner) equal to the aggregate DRO Amounts of all partners of the Partnership and (2) all other terms and conditions of the Partnership Agreement with respect to such deficit restoration obligation are met. For the avoidance of doubt, the purpose of this Section 3.8 is not to require the Partnership to incur or increase the amount of “recourse” indebtedness, if any, to which the Protected Properties are subject, provided, however, that the Partnership maintains at the same time sufficient other “recourse” indebtedness to cover the aggregate DRO Amounts of all partners of the Partnership.

3.9 Additional Guarantee and DRO Opportunities. Without limiting any of the other obligations of the Partnership under this Agreement, from and after the expiration of the Tax Protection Period, the Partnership shall, upon a request from a Protected Partner, use commercially reasonable efforts to permit such Protected Partner to enter into an agreement with the Partnership to bear the economic risk of loss as to a portion of the Partnership’s recourse indebtedness by undertaking an obligation to restore a portion of its negative capital account balance upon liquidation of such Protected Partner’s interest in the Partnership and/or to bear financial liability under a Guarantee Agreement substantially in the form of Schedule 3.7 hereto for indebtedness that would be considered Qualifying Guarantee Indebtedness under Section 3.2 hereof, if such Protected Partner shall provide information from its professional tax advisor satisfactory to the Partnership showing that, in the absence of such agreement, such Protected Partner likely would not be allocated from the Partnership sufficient indebtedness under Section 752 of the Code and the at-risk provisions under Section 465 of the Code to avoid the recognition of gain (other than gain required to be recognized by reason of actual cash distributions from the Partnership). The Partnership and its professional tax advisors shall cooperate in good faith with such Protected Partner and its professional tax advisors to provide such information regarding the allocation of the Partnership liabilities and the nature of such liabilities as is reasonably necessary in order to determine the Protected Partner’s adjusted tax basis in its Units and at-risk amount. If the Partnership permits a Protected Partner to enter into an agreement under this Section 3.9, the Partnership shall be under no further obligation with respect thereto, and the Partnership shall not be required to indemnify such Protected Partner for any damage incurred, in connection with or as a result of such agreement or the indebtedness, including without limitation a refinancing or prepayment thereof or taking any of the other actions required by Article 3 hereof with respect to Qualified Indebtedness. This Section 3.9 shall not obligate the Partnership to incur additional indebtedness.

12

ARTICLE 4

REMEDIES

4.1 Remedies. In the event that the Partnership engages in a transaction described in Section 2.1, 2.3 or 2.4 or the Partnership breaches its obligations set forth in Article 2 or Article 3 with respect to a Protected Partner, the Protected Partner’s sole right shall be to receive from the Partnership, and the Partnership shall pay, without duplication, to such Protected Partner as damages, an amount equal to:

plus in the case of either (a) or (b), an additional amount equal to the aggregate federal, state, and local income taxes (including any applicable federal unearned income Medicare contribution under Section 1411 of the Code) payable by the Protected Partner as a result of the receipt of any payment required under this Section 4.1 (including any tax liability incurred as a result of such Protected Partner’s receipt of such indemnity payment).

For purposes of computing the amount of federal, state, and local income taxes required to be paid by a Protected Partner, (i) any deduction for state income taxes payable as a result thereof actually allowed in computing federal income taxes shall be taken into account, and (ii) a Protected Partner’s tax liability shall be computed using the highest federal, state and local marginal income tax rates that would be applicable to such Protected Partner’s taxable income (taking into account the character and type of such income or gain) for the year with respect to which the taxes must be paid, without regard to any deductions, losses or credits that may be available to such Protected Partner that would reduce or offset its actual taxable income or actual tax liability if such deductions, losses or credits could be utilized by the Protected Partner to offset other income, gain or taxes of the Protected Partner, either in the current year, in earlier years, or in later years.

4.2 Process for Determining Payments Required Under this Article 4. If the Partnership or a Subsidiary engages in a transaction described in Sections 2.1, 2.3 or 2.4 or breached or violated any of the covenants set forth in Article 2 or Article 3 (or a Protected Partner asserts that the Partnership or a Subsidiary engaged in a transaction described in Sections 2.1, 2.3 or 2.4 or breached or violated any of the covenants set forth in Article 2 or Article 3), the Partnership and the Protected Partner agree to negotiate in good faith to resolve any disagreements regarding any such transaction, breach or violation and the amount of payments or damages, if any, payable to such Protected Partner under Section 4.1 (and to the extent applicable, Sections 4.4 and/or 4.5). If any such disagreement cannot be resolved by the Partnership and such Protected Partner within, as applicable, sixty (60) days after the receipt of notice from the Partnership of such transaction or breach pursuant to Section 4.3 and the amount of income to be recognized by reason thereof, (ii) 60 days after the receipt of a notice from the Protected Partner that the Partnership or a Subsidiary engaged in a transaction described in Sections 2.1, 2.3 or 2.4 or breached its obligations under this Agreement, which notice shall set forth the amount of income asserted to be recognized by the

13

Protected Partner and the payment required to be made to such Protected Partner under Section 4.1 as a result of the transaction or breach, (iii) 10 days following the date that the Partnership notifies the Protected Partner of its intention to settle, compromise and/or concede any Tax Claim or Proceeding pursuant to Section 7.2, or (iv) 10 days following any final determination of any Tax Claim or Proceeding, the Partnership and the Protected Partner shall jointly retain a nationally recognized independent “Big Four” public accounting firm (an “Accounting Firm”) to act as an arbitrator to resolve as expeditiously as possible all points of any such disagreement (including, without limitation, whether a transaction described in Sections 2.1, 2.3 or 2.4 has occurred or a breach of any of the covenants set forth Article 2 or Article 3 has occurred and, if so, the amount of payment or damages to which the Protected Partner is entitled as a result thereof, determined as set forth in Section 4.1 (and to the extent applicable, Section 4.4). All determinations made by the Accounting Firm with respect to any transaction described in Sections 2.1, 2.3 or 2.4 or the resolution of any breach or violation of any of the covenants set forth in Article 2 or Article 3 and the amount of payments or damages payable to the Protected Partner under Section 4.1 (and to the extent applicable, Section 4.4) shall be final, conclusive and binding on the Partnership and the Protected Partner. The fees and expenses of any Accounting Firm incurred in connection with any such determination shall be shared equally by the Partnership and the Protected Partner, provided that if the amount determined by the Accounting Firm to be owed by the Partnership to the Protected Partner is more than five percent (5%) higher than the amount proposed by the Partnership to be owed to such Protected Partner prior to the submission of the matter to the Accounting Firm, then all of the fees and expenses of any Accounting Firm incurred in connection with any such determination shall be paid by the Partnership and if the amount determined by the Accounting Firm to be owed by the Partnership to the Protected Partner is less than 95% of the amount than the amount proposed by the Partnership to be owed to such Protected Partner prior to the submission of the matter to the Accounting Firm, then all of the fees and expenses of any Accounting Firm incurred in connection with any such determination shall be paid by the Protected Partner.

In the case of any Tax Claim or Tax Proceeding that is resolved pursuant to a final determination or that is settled, compromised and/or conceded pursuant to Section 7.2, the amount of taxes due to the Internal Revenue Service (the “IRS”) or any other taxing authority shall, to the extent that such taxes relate to matters covered in this Agreement, be presumed to be an amount payable pursuant to this Agreement, and the amount payable pursuant to this Agreement shall be increased by any interest and penalties required to be paid by the Protected Partner with respect to such taxes (other than interest and penalties resulting from a failure of the Protected Partner to timely and properly file any tax return or to timely pay any tax, unless such failure resulted solely from the Protected Partner reporting and paying its taxes in a manner consistent with the Partnership) so that the amount of the payment under Section 4.1 shall not be less than the amount required to be paid to the IRS or any other taxing authority with respect to matters covered in this Agreement.

4.3 Required Notices; Time for Payment. In the event that there has been a transaction described in Sections 2.1, 2.3 or 2.4 or a breach of Article 2 or Article 3, the Partnership shall provide to the Protected Partner notice of the transaction or event giving rise to such breach not later than at such time as the Partnership provides to the Protected Partners the Schedule K-1’s to the Partnership’s federal income tax return as required in accordance with Section 7.4 below. All payments required under this Article 4 to any Protected Partner shall be made to such Protected Partner on or before April 15 of the year following the year in which the gain recognition event giving rise to such payment took place; provided that, if the Protected Partner is required to make estimated tax payments that would include such gain, the Partnership shall make a payment to the Protected Partner on or before the due date for such estimated tax payment and such payment from the partnership shall be in an amount that corresponds to the amount of the estimated tax being paid by such Protected Partner at such time. In the event of a payment required after the date required pursuant to this Section 4.3, interest shall accrue on the aggregate amount required to be paid from

14

such date to the date of actual payment at a rate equal to the “prime rate” of interest, as published in the Wall Street Journal (or if no longer published there, as announced by Citibank) effective as of the date the payment is required to be made.

4.4 Additional Damages for Breaches of Section 2.2(b), Section 3.2 and/or Section 3.3. Notwithstanding any of the foregoing in this Article 4, in the event that the Partnership should breach any of its covenants set forth in Section 2.2(b), Section 3.2 and/or Sections 3.3 (i), (ii) and/or (iii) and a Protected Partner is required to make a payment in respect of such indebtedness that it would not have had to make if such breach had not occurred (an “Excess Payment”), then, in addition to the damages provided for in the other Sections of this Article 4, the Partnership shall pay to such Protected Partner an amount equal to the sum of (i) the Excess Payment plus (ii) the aggregate federal, state and local income taxes, if any, computed or set forth in Section 4.1, required to be paid by such Protected Partner by reason of Section 4.4 becoming operative (for example, because the breach by the Partnership and this Section 4.4 caused all or any portion of the indebtedness in question no longer to be considered debt includible in basis by the affected Protected Partner pursuant to Treasury Regulations § 1.752-2(a)), plus (iii) an amount equal to the aggregate federal, state and local income taxes required to be paid by the Protected Partner (computed as set forth in Section 4.1) as a result of any payment required under this Section 4.4.

ARTICLE 5

SECTION 704(C) METHOD AND ALLOCATIONS

5.1 Application of “Traditional Method.” Notwithstanding any provision of the Partnership Agreement, the Partnership shall use the “traditional method” under Regulations § 1.704-3(b) for purposes of making all allocations under Section 704(c) of the Code, including, without limitation, allocations required in connection with the application of the “reverse 704(c) rules” pursuant to Treasury Regulations Sections 1.704-1(b)(2)(iv)(f)(4) and – (b)(4)(i) as a result of revaluations of assets of the Partnership (with no “curative allocations” to offset the effects of the “ceiling rule,” including upon any sale of a Protected Property).

ARTICLE 6

ALLOCATIONS OF LIABILITIES PURSUANT TO REGULATIONS UNDER SECTION 752

6.1 Allocation Methods to be Followed. Except as provided in Section 6.2, all tax returns prepared by the Partnership with respect to the Tax Protection Period (and to the extent arrangements have been entered into pursuant to Section 3.9, for so long thereafter as such arrangements are in effect) that allocate liabilities of the Partnership for purposes of Section 752 and the Treasury Regulations thereunder shall treat each Partner Guarantor as being allocated for federal income tax purposes an amount of recourse debt (in addition to any nonrecourse debt otherwise allocable to such Partner Guarantor in accordance with the Partnership Agreement and Treasury Regulations § 1.752-3 and any other recourse liabilities allocable to such Partner Guarantor by reason of guarantees of indebtedness or DROs entered into pursuant other agreements with the Partnership) pursuant to Treasury Regulation § 1.752-2 equal to such Partner Guarantor’s Minimum Liability Amount, as set forth on Schedule 3.1 hereto and as may be reduced pursuant to the terms of this Agreement, and the Partnership and the REIT shall not, during or with respect to the Tax Protection Period, take any contrary or inconsistent position in any federal or state income tax returns (including, without limitation, information returns, such as IRS Forms K-1, provided to partners in the Partnership and returns of Subsidiaries of the Partnership) or any dealings involving the IRS (including, without limitation, any audit, administrative appeal or any judicial proceeding involving the income tax returns of the Partnership or the tax treatment of any holder of partnership interests the Partnership).

15

6.2 Exception to Required Allocation Method. Notwithstanding the provisions of this Agreement, the Partnership shall not be required to make allocations of Guaranteed Debt or other recourse debt of the Partnership to the Protected Partners as set forth in this Agreement if and to the extent that the Partnership determines in good faith, based upon the advice of counsel recognized as expert in such matters or a nationally recognized public accounting firm, that there is no “substantial authority” (within the meaning of Section 6662(d)(2)(B)(i) of the Code) for such allocations or that there has been a judicial determination in a proceeding to which the Partnership is a party and as to which the Protected Partners have been allowed to participate as and to the extent contemplated in Article 7 to the effect that such allocations are not correct. In no event shall this Section 6.2 be construed to relieve the Partnership from any liability arising from a failure by the Partnership to comply with one or more of the provisions of Article 3 of this Agreement.

6.3 Cooperation in the Event of a Required Change. If a change in the Partnership’s allocations of Guaranteed Debt or other recourse debt of the Partnership to the Protected Partners is required by reason of circumstances described in Section 6.2, the Partnership and its professional tax advisors shall cooperate in good faith with each Protected Partner (or in the event of their death or disability, their executor, guardian or custodian, as applicable) and their professional tax advisors to develop alternative allocation arrangements and/or other mechanisms that protect the federal income tax positions of the Protected Partners in the manner contemplated by the allocations of Guaranteed Debt or other recourse debt of the Partnership to the Protected Partners as set forth in this Agreement.
