 (i) Each Member who has validly
elected to receive cash pursuant to an Election Form shall be entitled to receive an amount of cash equal to (x) the product of (A) the Member’s Share of the Aggregate Exchange Amount multiplied by (B) such Member’s
Cash Percentage multiplied by (C) 92.0%, less (y) any amount the OP determines it may be required to withhold for tax purposes; and

A “Member’s Cash Percentage” means the percentage of the consideration that such Member is entitled to receive in cash in
connection with the Merger in accordance with such Member’s Election Form (after taking into account any adjustment made by DF REIT to the percentage of the Merger Consideration to be received in cash by an Eligible Member, as described in the
CEM), subject to Section 4.1(f) hereof. 
 A “Member’s OP Unit Percentage” means the percentage of the
consideration that such Member is entitled to receive in OP Units in connection with the Merger in accordance with such Member’s Election Form (after taking into account any adjustment made by DF REIT to the percentage of the Merger

 (c) Any
Member that (i) did not complete both the Election Form and an Investor Questionnaire, the form of which was attached as an exhibit to the CEM (the “Investor Questionnaire”), and return them to DF REIT on or before the
deadline for electing consideration in the Merger set forth in the CEM (the “Election Deadline”), subject to the right of the OP, in its sole and absolute discretion, to accept such forms after the Election Deadline and prior
to the initial filing by DF REIT of its registration statement, to the extent practicable, (ii) is not an Eligible Member (as defined in the CEM), or (iii) did not specify a desired form of consideration to be received in the Merger, will
be deemed to have elected to receive cash, and no OP Units will be issued to such Member. 
 (d) The rights of holders of the OP Units as of
the Closing will be as set forth in the Amended and Restated Agreement of Limited Partnership of the OP (the “OP Agreement”). 
 (e) The OP shall issue OP Units only to those Members who have (i) made each of the representations and warranties set forth in Exhibit D hereof (which representations were included in the Investor
Questionnaire) and (ii) executed and delivered a Limited Partner Acceptance substantially in the form attached hereto as Exhibit E (the “Limited Partner Acceptance”). The name of each Member, and the number of OP
Units issued to such Member, shall be recorded in the books and records of the OP.

outstanding and shall be canceled and retired and shall cease to exist. 
 (g) The aggregate amount of consideration to be paid to the
Members pursuant to Section 4.1(b) hereof, plus any amounts withheld by the OP for tax purposes, shall be referred to as the “Merger Consideration.” 
 4.2 RIGHTS UPON EXCHANGE.

aggregate amount of the Merger Consideration paid upon the surrender for exchange of Membership Interests in accordance with the terms hereof shall be deemed to have been issued in full satisfaction of all rights pertaining to such Membership
Interests.

Investment Entity of Membership Interests which were outstanding immediately prior to the Effective Time.

 “Tax Protection Period” means the period commencing on the Closing Date and ending at 12:01 AM on January 1, 2018; provided,
however, that with respect to a Protected Partner, the Tax Protection Period shall terminate at such time as such Protected Partner has disposed of 50% or more of the Units received, directly or indirectly, in the Mergers by such Protected

 ARTICLE 2 
 RESTRICTIONS ON DISPOSITIONS OF 
 GAIN LIMITATION PROPERTIES 
 2.1 Restrictions on Disposition of Gain Limitation Properties. 
 (a) The Partnership agrees for the benefit of each Protected Partner, for the term of the Tax Protection Period, not to directly or indirectly sell, exchange, transfer, or otherwise dispose of a Gain Limitation
Property or any interest therein, without regard to whether such disposition is voluntary or involuntary, in a transaction that would cause the Protected Partners in the aggregate to recognize any Protected Gain in excess of the Annual Gain
Limitation. (For purposes of this Article 2, the Protected Gain recognized by each of the Protected Partners shall be deemed equal to the gain that would have been recognized without giving effect to any adjustment in basis that results with respect
to the indirect interest of such Protected Partner in such Gain Limitation Property, it being intended that the Annual Gain Limitation and the related definitions are to be applied to the Protected Partners as a group before giving effect to basis
adjustments. For example, and as an illustration only, if a Protected Partner who would have recognized $1,500,000 of gain with respect to the sale of a Gain Limitation Property has died, the Annual Gain Limitation and the related definitions shall
still be computed and applied as if such gain were recognized by such Protected Partner, notwithstanding the adjustment to tax basis that occurs with respect to such Protected Partner’s indirect interest in the Gain Limitation Property that
occurs upon the death of such Protected Partner.) 
 Without limiting the foregoing, the term “sale, exchange, transfer or
disposition” by the Partnership shall be deemed to include, and the prohibition shall extend to: 
  

	 	(a)	any direct or indirect disposition by any direct or indirect Subsidiary of any Gain Limitation Property or any interest therein; 

  

	 	(b)	any direct or indirect disposition by the Partnership of any Gain Limitation Property (or any direct or indirect interest therein) that is subject to Section 704(c)(1)(B) of
the Code and the Treasury Regulations thereunder; and 

  

	 	(c)	any distribution by the Partnership to a Protected Partner that is subject to Section 737 of the Code and the Treasury Regulations thereunder; 

 Without limiting the foregoing, a disposition shall include any transfer, voluntary or involuntary, by the Partnership or any Subsidiary in a foreclosure
proceeding, pursuant to a deed in lieu of foreclosure, or in a bankruptcy proceeding. 
 Notwithstanding the foregoing, this Section 2.1
shall not apply to a voluntary, actual disposition by a Protected Partner of Units in connection with a merger or consolidation of the Partnership pursuant to which (1) the Protected Partner is offered either cash or property treated as cash
pursuant to Section 731 of the Code (“Cash Consideration”) or partnership interests and the receipt of such partnership interests would not result in the recognition of gain for federal income tax purposes by the Protected Partner
(“Partnership Interest Consideration”); (2) the Protected Partner has the right 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; and (4) the Protected Partner elects or is deemed to
elect to receive Cash Consideration. 
  

 F-5 

 (b) Notwithstanding the restriction set forth in this Section 2.1, the Partnership and any
Subsidiary may dispose of any Gain Limitation Property (or any interest therein) if 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 recognition of any taxable income or gain to any
Protected Partner with respect to any of the Units; provided, however, that: 
 (i) in the case of a
Section 1031 like-kind exchange, if such exchange is with a “related party” within the meaning of Section 1031(f)(3) of the Code, any direct or indirect disposition by such related party of the Gain Limitation Property or any
other transaction prior to the expiration of the two (2) year period following such exchange that would cause Section 1031(f)(1) to apply with respect to such Gain Limitation Property (including by reason of the application of
Section 1031(f)(4)) shall be considered a violation of this Section 2.1 by the Partnership; and 
 (ii) in the event
that at the time of the exchange or other disposition the Protected Property is secured, directly or indirectly, by indebtedness that is guaranteed by a Protected Partner (or for which a Protected Partner otherwise has personal liability) and that
is not then in default and the transferee is not a Subsidiary of the Partnership that both is more than 50% owned, directly or indirectly by the Partnership and is and will continue to be under the legal control of the Partnership (which shall
include a partnership or limited liability company in which the Partnership or a wholly owned subsidiary of the Partnership is the sole managing general partner or sole managing member, as applicable), (a) either (I) such
indebtedness shall be repaid in full or (II) the Partnership shall obtain from the lenders with respect to such indebtedness a full and complete release of liability for each of the Protected Partners that has guaranteed, or otherwise has liability
for, such indebtedness, and (b) if such indebtedness is a Guaranteed Debt and the Tax Protection Period shall not have expired, the Partnership shall comply with its covenants set forth in Article 3 below with respect to such Guaranteed Debt
and the Partner Guarantors that are considered to have liability for such Guaranteed Debt (determined under Section 3.4 treating such events as a repayment of the Guaranteed Debt). 
 2.2 Annual Gain Limitation. For each Gain Limitation Year, the Annual Gain Limitation will be the sum of the Annual Gain Amount, plus the Gain
Limitation Carry-forward. 
 2.3 Allocation of Excess Protected Gain among Protected Partners. For each Gain Limitation Year, the
Excess Protected Gain (computed in accordance with the principles set forth in the parenthetical in the first paragraph of Section 2.1) will be allocated among Protected Partners in proportion to their Unadjusted Protected Gain Percentages
(computed in accordance with the principles set forth in the parenthetical in the first paragraph of Section 2.1) for purposes of determining the amount of Protected Gain recognized by a Protected Partner that is subject to reimbursement
pursuant to Article 4 hereof (for purpose of Article 4, the calculations of gain recognized by a Protected Partner and the reimbursement required shall be based upon the actual gain recognized by such Protected Partner without regard to the
principles set forth in the parenthetical in the first paragraph of Section 2.1). Specifically, for each Gain Limitation Year, the amount of Protected Gain for which a Protected Partner may be reimbursed under Article 4 hereof will equal the
product of (a) the Protected Partner’s Unadjusted 

  

 F-6 

 
Protected Gain Percentage (computed in accordance with the principles set forth in the parenthetical in the first paragraph of Section 2.1),
multiplied by (b) the Excess Protected Gain for such Gain Limitation Year (computed in accordance with the principles set forth in the parenthetical in the first paragraph of Section 2.1); provided, however, that no Protected
Partner shall be considered for this purpose to have recognized an amount of Protected Gain for a Gain Limitation Year that exceeds the Protected Gain actually recognized by such Protected Partner with respect to such Gain Limitation Year (computed
in accordance with the principles set forth in the parenthetical in the first paragraph of Section 2.1), and provided further, that the Protected Gain for which other Protected Partners are entitled to reimbursement shall be increased by
the portion of the Excess Protected Gain for such year not allocated to Protected Partners by reason of the immediately preceding limitation (with such allocation to be in accordance with the Protected Gain recognized by the Protected Partners not
subject to such limitation). Schedule 2.3 hereto sets forth an example that illustrates the application of this Section 2.3. 
 ARTICLE 3 
 ALLOCATION OF LIABILITIES AND GUARANTEE OPPORTUNITY AND DEFICIT 
 RESTORATION OBLIGATIONS 
 3.1
Minimum Liability Allocation. During the Tax Protection Period, the Partnership will offer to each Protected Partner 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 DROs, the Partnership will use the optional method under Treasury Regulations
Section 1.752-3(a)(3) to allocate Nonrecourse Liabilities considered secured by a Gain Limitation 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 Gain Limitation 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 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: 
  

 F-7 

	 	(i)	each such guarantee shall be a “bottom dollar guarantee” in that the lender for the Guaranteed Debt is required to pursue all other collateral and security for the
Guaranteed Debt (other than any “bottom dollar guarantees” permitted pursuant to this clause (i) and/or Section 3.3 below) prior to seeking to collect on such a guarantee, and the lender shall have recourse against the guarantee
only if, and solely to the extent that, the total amount recovered by the lender with respect to the Guaranteed Debt after the lender has exhausted its remedies as set forth above is less than the aggregate of the Guaranteed Amounts with respect to
such Guaranteed Debt (plus the aggregate amounts of any other guarantees (x) that are in effect with respect to such Guaranteed Debt at the time the guarantees pursuant to this Article 3 are entered into, or (y) that are entered into after
the date the guarantees pursuant to this Article 4 are entered into with respect to such Guaranteed Debt and that comply with Section 3.5 below, but only to the extent that, in either case, such guarantees are “bottom dollar
guarantees” with respect to the Guaranteed Debt), and the maximum aggregate liability of each Partner Guarantor for all Guaranteed Debt shall be limited to the amount actually guaranteed by such Partner Guarantor; 

  

	 	(ii)	the fair market value of the collateral against which the lender has recourse pursuant to the Guaranteed Debt, determined as of the time the guarantee is entered into (an
independent appraisal relied upon by the lender in making the loan shall be conclusive evidence of such fair market value when the guarantee is being entered into in connection with the closing of such loan), shall not be less than 150% of the sum
of (x) the aggregate of the Guaranteed Amounts with respect to such Guaranteed Debt, plus (y) the dollar amount of any other indebtedness that is senior to or pari passu with the Guaranteed Debt and as to which the lender thereunder has
recourse against property that is collateral of the Guaranteed Debt, plus (z) the aggregate amounts of any other guarantees (A) that are in effect with respect to such Guaranteed Debt at the time the guarantees pursuant to this Article 3
are entered into with respect to such Guaranteed Debt and that comply with Section 3(e) below, but only to the extent that such guarantees are “bottom dollar guarantees with respect to the Guaranteed Debt); 

  

	 	(iii)	(A) the executed guarantee must be delivered to the lender and (B) (i) the execution of the guarantee by the Partner Guarantors must be acknowledged by the lender as an
inducement to it to make a new loan, to continue an existing loan (which continuation is not otherwise required), or to grant a material consent under an existing loan (which consent is not otherwise required to be granted) or, alternatively,
(ii) the guarantee otherwise must be enforceable under the laws of the state governing the loan and in which the property securing the loan is located or in which the lender has a significant place of business (with any bona fide branch or
office of the lender through which the loan is made, negotiated, or administered being deemed a “significant place of business” for the purposes hereof); 

  

 F-8 

	 	(iv)	as to each Partner Guarantor that is executing a guarantee pursuant to this Agreement, there must be no other Person that would be considered to “bear the economic risk of
loss,” within the meaning of Treasury Regulation § 1.752-2, or would be considered to be “at risk” for purposes of Section 465(b) with respect to that portion of such debt for which such Partner Guarantor is being made
liable for purposes of satisfying the Partnership’s obligations to such Partner Guarantor under this Article 3; 

  

	 	(v)	the obligor with respect to the Guaranteed Debt is the Partnership or an entity which is and will continue to be under the legal control of the Partnership (which shall include a
partnership or limited liability company in which the Partnership or a wholly-owned subsidiary of the Partnership is the sole managing general partner or sole managing member, as applicable). 

 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)(ii) 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(ii) 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 either (1) to enter into a Qualified Guarantee of other the 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 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 amount sufficient so that, taking into account such
guarantees of such other Qualified Guarantee Indebtedness, 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 

  

 F-9 

 
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) 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) and 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 either to
guarantee Qualified Guarantee Indebtedness or enter into a DRO, the Partnership shall be considered to have satisfied its obligation 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) the Guarantee Agreement or DRO, 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 a brief letter explaining 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, a brief description of the collateral for the Qualified Guarantee Indebtedness, a statement of the amount to be guaranteed, the address to which the executed Guarantee Agreement or DRO, as applicable, must be
sent and the date by which it must be received, and a statement to the effect that, if the Protected Partner fails to execute and return such Agreement 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 made available for 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 procedure, the Partnership shall have not 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. 
 3.7 Presumption as to Schedule 3.7. The form of the Guarantee Agreement attached hereto as Schedule 3.7 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: 
  

	 	(i)	there are no other guarantees in effect with respect to such Guaranteed Debt (other than the guarantees contemporaneously being entered into by the Partner Guarantors pursuant to
this Article 3); 

  

	 	(ii)	the collateral securing such Guaranteed Debt is not, and shall not thereafter become, collateral for any other indebtedness that is senior to or pari passu with such Guaranteed
Debt; 

  

 F-10 

	 	(iii)	no additional guarantees with respect to such Guaranteed Debt will be entered into during the applicable Tax Protection Period pursuant to the proviso set forth in
Section 3.3; 

  

	 	(iv)	the lender with respect to such Guaranteed Debt is not the Partnership, any Subsidiary or other entity in which the Partnership owns a direct or indirect interest, the REIT, any
other partner in the Partnership, or any person related to any partner in the Partnership as determined for purposes of Treasury Regulation § 1.752-2 or any person that would be considered a “related party” as determined for
purposes of Section 465 of the Code; and 

  

	 	(v)	none of the REIT, nor any other partner in the Partnership, nor any person related to any partner in the Partnership as determined for purposes of Treasury Regulation
§ 1.752-2 shall have provided, or shall thereafter provide, collateral for, or otherwise shall have entered into, or shall thereafter enter into, a relationship that would cause such person or entity to be considered to bear the risk of
loss with respect to such Guaranteed Debt, as determined for purposes of Treasury Regulation § 1.752-2 or that would cause such entity to be considered “at risk” with respect to such Guaranteed Debt, as determined for purposes of
Section 465 of the Code. 

 3.8 Deficit Restoration Obligation. 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 amounts subject to a DRO of all Protected Partners and 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. 
 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 

  

 F-11 

 
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. 
 ARTICLE 4 
 REMEDIES FOR BREACH 
 4.1 Monetary Damages. In the event that the Partnership breaches its obligations set forth in Article 2, Article 3, or Article 6 with respect to a
Protected Partner the Protected Partner’s sole right shall be to receive from the Partnership, and the Partnership shall pay to such Protected Partner as damages, an amount equal to: 
  

	 	(a)	in the case of a violation of Articles 3 or 6, the aggregate federal, state and local income taxes incurred by the Protected Partner or an Indirect Owner as a result of the income
or gain allocated to, or otherwise recognized by, such Protected Partner with respect to its Units by reason of such breach; 

  

	 	(b)	in the case of a violation of Article 2, the aggregate federal state, and local income taxes incurred by the Protected Partner or an Indirect Owner with respect the Excess Protected
Gain incurred with respect to the Gain Limitation Property that is allocable to such Protected Partner under the Partnership Agreement and Section 2.3 hereof (computed without regard to the principles set forth in the parenthetical in the first
paragraph of Section 2.1); 

 plus in the case of either (a) or (b), an amount equal to the aggregate federal, state,
and local income taxes payable by the Protected Partner or an Indirect Owner as a result of the receipt of any payment required under this Section 4.1. 
 For purposes of computing the amount of federal, state, and local income taxes required to be paid by a Protected Partner (or Indirect Owner), (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 (or Indirect Owner’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 (or Indirect Owner’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 (or Indirect Owner) 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 (or Indirect Owner) to offset other income, gain or taxes of the Protected Partner(or Indirect Owner), either in the current year, in earlier years, or in later years). 
 4.2 Process for Determining Damages. If the Partnership has breached or violated any of the covenants set forth in Article 2, Article 3, or
Article 6 (or a Protected Partner asserts that the Partnership has breached or violated any of the covenants set forth in Article 2, Article 3, or Article 6), the Partnership and the Protected Partner (or Indirect Owner) agree to negotiate in good
faith to resolve any 

  

 F-12 

 
disagreements regarding any such breach or violation and the amount of damages, if any, payable to such Protected Partner (or Indirect Owner) under
Section 4.1 (and to the extent applicable, Sections 4.4). If any such disagreement cannot be resolved by the Partnership and such Protected Partner (or Indirect Owner) within sixty (60) days after the receipt of notice from the Partnership
of such breach and the amount of income to be recognized by reason thereof (or, if applicable, receipt by the Partnership of an assertion by a Protected Partner that the Partnership has breached or violated any of the covenants set forth in Article
2, Article 3, or Article 6), the Partnership and the Protected Partner shall jointly retain a nationally recognized independent 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 breach of any of the covenants set forth Article 2, Article 3, or Article 6, has occurred and, if so, the amount of 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 the resolution of any breach or violation of any of the covenants set forth
in Article 2, Article 3, or Article 6 and the amount of 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 more than
five percent (5%) less 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. 
 4.3 Required Notices; Time for Payment. In the event
that there has been a breach of Article 2, Article 3, or Article 6 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 7.3 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 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 2.1(b)(ii), 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 2.1(b)(ii), Section 3.2, and/or Sections 3.3 (i) and/or (ii) and a Protected Partner (or Indirect Owner)
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 (or Indirect Owner) 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 

  

 F-13 

 
be paid by such Protected Partner (or Indirect Owner) 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 (or Indirect Owner) (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 with respect to the properties
contributed to the Partnership in connection with the initial public offering of the REIT’s shares of common stock. 
 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
Protected 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 Guaranteed Amount, 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 Forms K-1, provided to partners in the Partnership and returns of Subsidiaries of the Partnership) or any dealings
involving the Internal Revenue Service (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). 
 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 that it may not be more
likely than not that such allocations will be respected; provided that the Partnership shall provide to each Protected Partner (or in the event of their death or disability, their executor, guardian or custodian, as applicable), notice of
such determination and if, within forty-five (45) days after the receipt thereof, the Partnership is provided an opinion of a law firm recognized as expert in such matters or a nationally recognized public accounting firm to the effect that it
is more likely than not that such allocations will be respected, the Partnership shall continue to make allocations of Guaranteed Debt or other recourse debt of the Partnership to the Protected Partners as set forth in this Agreement; provided
further that if there shall have been a judicial determination in a proceeding to which the Partnership is a party and as to which the General Partners have been allowed to participate as and to the extent contemplated in Article 6 to the effect
that such allocations are not correct, Section 6.1 shall not apply unless the matter is being appealed to an 

  

 F-14 

 
applicable court of appeals, the requirements of Section 7.2 shall have been satisfied in connection therewith, and the opinion described above from
counsel or accountants engaged by a Protected Partner shall have been provided. In no event shall this Section 6.2 be construed to relieve the Partnership for 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 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. 
 ARTICLE 7 
 TAX PROCEEDINGS

 7.1 Notice of Tax Audits. If any claim, demand, assessment (including a notice of proposed assessment) or other assertion is
made with respect to taxes against the Protected Partners or the Partnership the calculation of which involves a matter covered in this Agreement that could result in tax liability to a Protected Partner (“Tax Claim”) or if the REIT or the
Partnership receives any notice from any jurisdiction with respect to any current or future audit, examination, investigation or other proceeding (“Tax Proceeding”) involving the Protected Partners or the Partnership or that otherwise
could involve a matter covered in this Agreement and would reasonably be expected to directly or indirectly affect the Protected Partners in an adverse manner, then the REIT or the Partnership, as applicable shall promptly notify the Protected
Partners of such Tax Claim or Tax Proceeding. 
 7.2 Control of Tax Proceedings. The REIT, as the general partner of the Partnership
shall have the right to control the defense, settlement or compromise of any Proceeding or Tax Claim; provided, however, that the REIT shall not consent to the entry of any judgment or enter into any settlement with respect to such Tax
Claim or Tax Proceeding that would result in tax liability to one or more Protected Partners without the prior written consent of the affected Protected Partners (unless, and only to the extent, that any taxes required to be paid by the Protected
Partners as a result thereof would be required to be reimbursed by the Partnership and the REIT under Article 4 and the Partnership and the REIT agree in connection with such settlement or consent, to make such required payments); provided
further that the Partnership shall keep the Protected Partners informed of the progress thereof to the extent that such Proceeding or Tax Claim would reasonably be expected to directly or indirectly affect the Protected Partners in an adverse
manner. 
 7.3 Timing of Tax Returns; Periodic Tax Information. The Partnership shall cause to be delivered to each Protected Partner,
as soon as reasonably practicable each year, the Forms K-1 that the Partnership is required to deliver to such Protected Partners with respect to the prior taxable year. In addition, the Partnership agrees to provide to the Protected Partners, upon
request, an estimate of the taxable income expected to be allocable for a specified taxable year from the Partnership to each Protected Partner and the entities that they control, provided that such estimates shall not be required to be
provided more frequently than once each calendar quarter.

limited liability company (the “Investment Entity”), DuPont Fabros Technology, Inc., a Maryland corporation (“DF REIT”), and DuPont Fabros Technology L.P., a Maryland limited partnership and
operating subsidiary of DF REIT (the “OP”). 
 RECITALS 
 WHEREAS, DF REIT and the OP are considering engaging in a series of related transactions pursuant to which, among other things, (i) the OP would
acquire interests in various limited liability companies that own, among other assets, real property, and (ii) DF REIT would effect an initial public offering of its shares of common stock, par value $0.001 per share (“REIT
Shares”), and contribute the proceeds therefrom for a like number of units of limited partnership interest in the OP (“OP Units”) (the “IPO,” and together with the other transactions in
connection therewith, the “IPO Transactions”); 
 WHEREAS, the parties hereto have determined that, in order to
facilitate the IPO, it is in their respective best interests, on the terms and subject to the conditions hereinafter set forth, that (i) the Investment Entity be merged with and into the OP, with the OP surviving, (ii) the outstanding
limited liability company interests in the Investment Entity (the “Membership Interests”) be converted into the right to receive the Merger Consideration (as defined below), and (iii) the OP succeed to the liabilities of
the Investment Entity arising as a result of the Merger (as defined below); 
 WHEREAS, Lemur Management LLC, a Delaware limited liability
company and the managing member of the Investment Entity (the “Managing Member”), has determined that the Merger, including this Agreement, is advisable, fair to, and in the best interest of holders of Membership Interests
(“Members”), and has approved the Merger and this Agreement, and resolved to recommend that the Members approve the Merger and this Agreement, pursuant to a written consent of the Managing Member dated as of August 7,
2007; 
 WHEREAS, DF REIT, as the general partner of the OP, has determined that the Merger, including this Agreement, is advisable, fair to
and in the best interests of the OP and its limited partners, and has approved the Merger and this Agreement, and directed that the Merger and this Agreement be submitted for consideration by the limited partners of the OP, pursuant to a unanimous
written consent of the board of directors of DF REIT dated as of August 7, 2007;

 4.1
EFFECT ON MEMBERSHIP INTERESTS. 
 (a) In connection with the Merger and related transactions, DF REIT and the OP have previously
delivered to each Member the CEM, including the Election Form, pursuant to which, among other things, in connection with the Merger and subject to certain conditions and eligibility requirements set forth in the CEM, DF REIT and the OP offered each
Member the option to receive as consideration in the Merger either (i) cash, (ii) if eligible, OP Units, or (iii) if eligible, a combination of the two, in exchange for each such Member’s Membership Interests. 
 (b) At the Effective Time, by virtue of the Merger and the duly executed Election Form submitted by each Member as of the date hereof, and without any
further action on the part of any such Member (with certain terms defined in Exhibit C hereto): 
 (i) Each Member who has validly
elected to receive cash pursuant to an Election Form shall be entitled to receive an amount of cash equal to (x) the product of (A) the Member’s Share of the Aggregate Exchange Amount multiplied by (B) such Member’s
Cash Percentage multiplied by (C) 92.0%, less (y) any amount the OP determines it may be required to withhold for tax purposes; and 
 (ii) Each eligible Member who has validly elected to receive OP Units pursuant to an Election Form shall be entitled to receive a number of OP Units equal to (x) the product of (A) the Member’s Share of
the Aggregate Exchange Amount multiplied by (B) such Member’s OP Unit Percentage divided by (y) the initial public offering price of a share of DF REIT common stock.

 A “Member’s Share of the Aggregate Exchange Amount” means the product of

A “Member’s Cash Percentage” means the percentage of the consideration that such Member is entitled to receive in cash in
connection with the Merger in accordance with such Member’s Election Form (after taking into account any adjustment made by DF REIT to the percentage of the Merger Consideration to be received in cash by an Eligible Member, as described in the
CEM), subject to Section 4.1(f) hereof. 
 A “Member’s OP Unit Percentage” means the percentage of the
consideration that such Member is entitled to receive in OP Units in connection with the Merger in accordance with such Member’s Election Form (after taking into account any adjustment made by DF REIT to the percentage of the Merger
Consideration to be received in cash by an Eligible Member, as described in the CEM), subject to Section 4.1(f) hereof. 
 (c) Any
Member that (i) did not complete both the Election Form and an Investor Questionnaire, the form of which was attached as an exhibit to the CEM (the “Investor Questionnaire”), and return them to DF REIT on or before the
deadline for electing consideration in the Merger set forth in the CEM (the “Election Deadline”), subject to the right of the OP, in its sole and absolute discretion, to accept such forms after the Election Deadline and prior
to the initial filing by DF REIT of its registration statement, to the extent practicable, (ii) is not an Eligible Member (as defined in the CEM), or (iii) did not specify a desired form of consideration to be received in the Merger, will
be deemed to have elected to receive cash, and no OP Units will be issued to such Member. 
 (d) The rights of holders of the OP Units as of
the Closing will be as set forth in the Amended and Restated Agreement of Limited Partnership of the OP (the “OP Agreement”). 
 (e) The OP shall issue OP Units only to those Members who have (i) made each of the representations and warranties set forth in Exhibit D hereof (which representations were included in the Investor
Questionnaire) and (ii) executed and delivered a Limited Partner Acceptance substantially in the form attached hereto as Exhibit E (the “Limited Partner Acceptance”). The name of each Member, and the number of OP
Units issued to such Member, shall be recorded in the books and records of the OP. 
 (f) Each Membership Interest shall no longer be
outstanding and shall be canceled and retired and shall cease to exist. 
 (g) The aggregate amount of consideration to be paid to the
Members pursuant to Section 4.1(b) hereof, plus any amounts withheld by the OP for tax purposes, shall be referred to as the “Merger Consideration.” 
 4.2 RIGHTS UPON EXCHANGE. 
 (a) The
aggregate amount of the Merger Consideration paid upon the surrender for exchange of Membership Interests in accordance with the terms hereof shall be deemed to have been issued in full satisfaction of all rights pertaining to such Membership
Interests.

 (b) At and after the Effective Time, there shall be no transfers on the books and records of the
Investment Entity of Membership Interests which were outstanding immediately prior to the Effective Time. 
 (c) No fractional OP Units shall
be issued pursuant hereto. The number of OP Units issued to any holder of Membership Interests immediately prior to the Effective Time shall be rounded to the nearest whole OP Unit.

restrictive covenant, statute, rule, or regulation applicable to the Investment Entity.

 (i) Securities Laws Matters. The Investment Entity, for itself and each of the Members, acknowledges that (i) DF REIT and the OP intend the
offer and issuance of any OP Units to any Eligible Member (as defined in the CEM) to be exempt from registration under the Securities Act of 1933, as amended (the “Securities Act”), and applicable state securities laws by

Protected Partner under Section 704(c) of the Code in the event of the sale of a Gain Limitation Property in a fully taxable transaction (excluding its
corresponding share of “book gain,” if any). The initial amount of Protected Gain with respect to each Protected Partner shall be determined as if the Partnership sold each Gain Limitation Property in a fully taxable transaction on the

 “Tax Protection Period” means the period commencing on the Closing Date and ending at 12:01 AM on January 1, 2018; provided,
however, that with respect to a Protected Partner, the Tax Protection Period shall terminate at such time as such Protected Partner has disposed of 50% or more of the Units received, directly or indirectly, in the Mergers by such Protected

 ARTICLE 2 
 RESTRICTIONS ON DISPOSITIONS OF 
 GAIN LIMITATION PROPERTIES 
 2.1 Restrictions on Disposition of Gain Limitation Properties. 
 (a) The Partnership agrees for the benefit of each Protected Partner, for the term of the Tax Protection Period, not to directly or indirectly sell, exchange, transfer, or otherwise dispose of a Gain Limitation
Property or any interest therein, without regard to whether such disposition is voluntary or involuntary, in a transaction that would cause the Protected Partners in the aggregate to recognize any Protected Gain in excess of the Annual Gain
Limitation. (For purposes of this Article 2, the Protected Gain recognized by each of the Protected Partners shall be deemed equal to the gain that would have been recognized without giving effect to any adjustment in basis that results with respect
to the indirect interest of such Protected Partner in such Gain Limitation Property, it being intended that the Annual Gain Limitation and the related definitions are to be applied to the Protected Partners as a group before giving effect to basis
adjustments. For example, and as an illustration only, if a Protected Partner who would have recognized $1,500,000 of gain with respect to the sale of a Gain Limitation Property has died, the Annual Gain Limitation and the related definitions shall
still be computed and applied as if such gain were recognized by such Protected Partner, notwithstanding the adjustment to tax basis that occurs with respect to such Protected Partner’s indirect interest in the Gain Limitation Property that
occurs upon the death of such Protected Partner.) 
 Without limiting the foregoing, the term “sale, exchange, transfer or
disposition” by the Partnership shall be deemed to include, and the prohibition shall extend to: 
  

	 	(a)	any direct or indirect disposition by any direct or indirect Subsidiary of any Gain Limitation Property or any interest therein; 

  

	 	(b)	any direct or indirect disposition by the Partnership of any Gain Limitation Property (or any direct or indirect interest therein) that is subject to Section 704(c)(1)(B) of
the Code and the Treasury Regulations thereunder; and 

  

	 	(c)	any distribution by the Partnership to a Protected Partner that is subject to Section 737 of the Code and the Treasury Regulations thereunder; 

 Without limiting the foregoing, a disposition shall include any transfer, voluntary or involuntary, by the Partnership or any Subsidiary in a foreclosure
proceeding, pursuant to a deed in lieu of foreclosure, or in a bankruptcy proceeding. 
 Notwithstanding the foregoing, this Section 2.1
shall not apply to a voluntary, actual disposition by a Protected Partner of Units in connection with a merger or consolidation of the Partnership pursuant to which (1) the Protected Partner is offered either cash or property treated as cash
pursuant to Section 731 of the Code (“Cash Consideration”) or partnership interests and the receipt of such partnership interests would not result in the recognition of gain for federal income tax purposes by the Protected Partner
(“Partnership Interest Consideration”); (2) the Protected Partner has the right to 

  

 F-5 

 
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; and (4) the Protected Partner elects or is deemed to
elect to receive Cash Consideration. 
 (b) Notwithstanding the restriction set forth in this Section 2.1, the Partnership and any
Subsidiary may dispose of any Gain Limitation Property (or any interest therein) if 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 recognition of any taxable income or gain to any
Protected Partner with respect to any of the Units; provided, however, that: 
 (i) in the case of a
Section 1031 like-kind exchange, if such exchange is with a “related party” within the meaning of Section 1031(f)(3) of the Code, any direct or indirect disposition by such related party of the Gain Limitation Property or any
other transaction prior to the expiration of the two (2) year period following such exchange that would cause Section 1031(f)(1) to apply with respect to such Gain Limitation Property (including by reason of the application of
Section 1031(f)(4)) shall be considered a violation of this Section 2.1 by the Partnership; and 
 (ii) in the event
that at the time of the exchange or other disposition the Protected Property is secured, directly or indirectly, by indebtedness that is guaranteed by a Protected Partner (or for which a Protected Partner otherwise has personal liability) and that
is not then in default and the transferee is not a Subsidiary of the Partnership that both is more than 50% owned, directly or indirectly by the Partnership and is and will continue to be under the legal control of the Partnership (which shall
include a partnership or limited liability company in which the Partnership or a wholly owned subsidiary of the Partnership is the sole managing general partner or sole managing member, as applicable), (a) either (I) such
indebtedness shall be repaid in full or (II) the Partnership shall obtain from the lenders with respect to such indebtedness a full and complete release of liability for each of the Protected Partners that has guaranteed, or otherwise has liability
for, such indebtedness, and (b) if such indebtedness is a Guaranteed Debt and the Tax Protection Period shall not have expired, the Partnership shall comply with its covenants set forth in Article 3 below with respect to such Guaranteed Debt
and the Partner Guarantors that are considered to have liability for such Guaranteed Debt (determined under Section 3.4 treating such events as a repayment of the Guaranteed Debt). 
 2.2 Annual Gain Limitation. For each Gain Limitation Year, the Annual Gain Limitation will be the sum of the Annual Gain Amount, plus the Gain
Limitation Carry-forward. 
 2.3 Allocation of Excess Protected Gain among Protected Partners. For each Gain Limitation Year, the
Excess Protected Gain (computed in accordance with the principles set forth in the parenthetical in the first paragraph of Section 2.1) will be allocated among Protected Partners in proportion to their Unadjusted Protected Gain Percentages
(computed in accordance with the principles set forth in the parenthetical in the first paragraph of Section 2.1) for purposes of determining the amount of Protected Gain recognized by a Protected Partner that is subject to reimbursement
pursuant to Article 4 hereof (for purpose of Article 4, the calculations of gain recognized by a Protected Partner and the reimbursement required shall be based upon the actual gain recognized by such Protected Partner without 

  

 F-6 

 
regard to the principles set forth in the parenthetical in the first paragraph of Section 2.1). Specifically, for each Gain Limitation Year, the amount
of Protected Gain for which a Protected Partner may be reimbursed under Article 4 hereof will equal the product of (a) the Protected Partner’s Unadjusted Protected Gain Percentage (computed in accordance with the principles set forth in
the parenthetical in the first paragraph of Section 2.1), multiplied by (b) the Excess Protected Gain for such Gain Limitation Year (computed in accordance with the principles set forth in the parenthetical in the first paragraph of
Section 2.1); provided, however, that no Protected Partner shall be considered for this purpose to have recognized an amount of Protected Gain for a Gain Limitation Year that exceeds the Protected Gain actually recognized by such
Protected Partner with respect to such Gain Limitation Year (computed in accordance with the principles set forth in the parenthetical in the first paragraph of Section 2.1), and provided further, that the Protected Gain for which other
Protected Partners are entitled to reimbursement shall be increased by the portion of the Excess Protected Gain for such year not allocated to Protected Partners by reason of the immediately preceding limitation (with such allocation to be in
accordance with the Protected Gain recognized by the Protected Partners not subject to such limitation). Schedule 2.3 hereto sets forth an example that illustrates the application of this Section 2.3. 
 ARTICLE 3 
 ALLOCATION OF LIABILITIES
AND GUARANTEE OPPORTUNITY AND DEFICIT 
 RESTORATION OBLIGATIONS 
 3.1 Minimum Liability Allocation. During the Tax Protection Period, the Partnership will offer to each Protected Partner 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 DROs, the Partnership will use the optional method under Treasury Regulations Section 1.752-3(a)(3) to allocate Nonrecourse Liabilities considered secured by a Gain Limitation 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 Gain Limitation 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 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: 
  

 F-7 

	 	(i)	each such guarantee shall be a “bottom dollar guarantee” in that the lender for the Guaranteed Debt is required to pursue all other collateral and security for the
Guaranteed Debt (other than any “bottom dollar guarantees” permitted pursuant to this clause (i) and/or Section 3.3 below) prior to seeking to collect on such a guarantee, and the lender shall have recourse against the guarantee
only if, and solely to the extent that, the total amount recovered by the lender with respect to the Guaranteed Debt after the lender has exhausted its remedies as set forth above is less than the aggregate of the Guaranteed Amounts with respect to
such Guaranteed Debt (plus the aggregate amounts of any other guarantees (x) that are in effect with respect to such Guaranteed Debt at the time the guarantees pursuant to this Article 3 are entered into, or (y) that are entered into after
the date the guarantees pursuant to this Article 4 are entered into with respect to such Guaranteed Debt and that comply with Section 3.5 below, but only to the extent that, in either case, such guarantees are “bottom dollar
guarantees” with respect to the Guaranteed Debt), and the maximum aggregate liability of each Partner Guarantor for all Guaranteed Debt shall be limited to the amount actually guaranteed by such Partner Guarantor; 

  

	 	(ii)	the fair market value of the collateral against which the lender has recourse pursuant to the Guaranteed Debt, determined as of the time the guarantee is entered into (an
independent appraisal relied upon by the lender in making the loan shall be conclusive evidence of such fair market value when the guarantee is being entered into in connection with the closing of such loan), shall not be less than 150% of the sum
of (x) the aggregate of the Guaranteed Amounts with respect to such Guaranteed Debt, plus (y) the dollar amount of any other indebtedness that is senior to or pari passu with the Guaranteed Debt and as to which the lender thereunder has
recourse against property that is collateral of the Guaranteed Debt, plus (z) the aggregate amounts of any other guarantees (A) that are in effect with respect to such Guaranteed Debt at the time the guarantees pursuant to this Article 3
are entered into with respect to such Guaranteed Debt and that comply with Section 3(e) below, but only to the extent that such guarantees are “bottom dollar guarantees with respect to the Guaranteed Debt); 

  

	 	(iii)	(A) the executed guarantee must be delivered to the lender and (B) (i) the execution of the guarantee by the Partner Guarantors must be acknowledged by the lender as an
inducement to it to make a new loan, to continue an existing loan (which continuation is not otherwise required), or to grant a material consent under an existing loan (which consent is not otherwise required to be granted) or, alternatively,
(ii) the guarantee otherwise must be enforceable under the laws of the state governing the loan and in which the property securing the loan is located or in which the lender has a significant place of business (with any bona fide branch or
office of the lender through which the loan is made, negotiated, or administered being deemed a “significant place of business” for the purposes hereof); 

  

 F-8 

	 	(iv)	as to each Partner Guarantor that is executing a guarantee pursuant to this Agreement, there must be no other Person that would be considered to “bear the economic risk of
loss,” within the meaning of Treasury Regulation § 1.752-2, or would be considered to be “at risk” for purposes of Section 465(b) with respect to that portion of such debt for which such Partner Guarantor is being made
liable for purposes of satisfying the Partnership’s obligations to such Partner Guarantor under this Article 3; 

  

	 	(v)	the obligor with respect to the Guaranteed Debt is the Partnership or an entity which is and will continue to be under the legal control of the Partnership (which shall include a
partnership or limited liability company in which the Partnership or a wholly-owned subsidiary of the Partnership is the sole managing general partner or sole managing member, as applicable). 

 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)(ii) 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(ii) 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 either (1) to enter into a Qualified Guarantee of other the 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 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 amount sufficient so that, taking into account such
guarantees of such other Qualified Guarantee Indebtedness, 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. 
  

 F-9 

 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) 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) and 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 either to
guarantee Qualified Guarantee Indebtedness or enter into a DRO, the Partnership shall be considered to have satisfied its obligation 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) the Guarantee Agreement or DRO, 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 a brief letter explaining 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, a brief description of the collateral for the Qualified Guarantee Indebtedness, a statement of the amount to be guaranteed, the address to which the executed Guarantee Agreement or DRO, as applicable, must be
sent and the date by which it must be received, and a statement to the effect that, if the Protected Partner fails to execute and return such Agreement 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 made available for 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 procedure, the Partnership shall have not 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. 
 3.7 Presumption as to Schedule 3.7. The form of the Guarantee Agreement attached hereto as Schedule 3.7 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: 
  

	 	(i)	there are no other guarantees in effect with respect to such Guaranteed Debt (other than the guarantees contemporaneously being entered into by the Partner Guarantors pursuant to
this Article 3); 

  

 F-10 

	 	(ii)	the collateral securing such Guaranteed Debt is not, and shall not thereafter become, collateral for any other indebtedness that is senior to or pari passu with such Guaranteed
Debt; 

  

	 	(iii)	no additional guarantees with respect to such Guaranteed Debt will be entered into during the applicable Tax Protection Period pursuant to the proviso set forth in
Section 3.3; 

  

	 	(iv)	the lender with respect to such Guaranteed Debt is not the Partnership, any Subsidiary or other entity in which the Partnership owns a direct or indirect interest, the REIT, any
other partner in the Partnership, or any person related to any partner in the Partnership as determined for purposes of Treasury Regulation § 1.752-2 or any person that would be considered a “related party” as determined for purposes
of Section 465 of the Code; and 

  

	 	(v)	none of the REIT, nor any other partner in the Partnership, nor any person related to any partner in the Partnership as determined for purposes of Treasury Regulation § 1.752-2
shall have provided, or shall thereafter provide, collateral for, or otherwise shall have entered into, or shall thereafter enter into, a relationship that would cause such person or entity to be considered to bear the risk of loss with respect to
such Guaranteed Debt, as determined for purposes of Treasury Regulation § 1.752-2 or that would cause such entity to be considered “at risk” with respect to such Guaranteed Debt, as determined for purposes of Section 465 of the
Code. 

 3.8 Deficit Restoration Obligation. 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 amounts subject to a DRO
of all Protected Partners and 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. 
 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 

  

 F-11 

 
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. 
 ARTICLE 4 
 REMEDIES FOR BREACH 
 4.1 Monetary Damages. In the event that the Partnership breaches its
obligations set forth in Article 2, Article 3, or Article 6 with respect to a Protected Partner the Protected Partner’s sole right shall be to receive from the Partnership, and the Partnership shall pay to such Protected Partner as damages, an
amount equal to: 
  

	 	(a)	in the case of a violation of Articles 3 or 6, the aggregate federal, state and local income taxes incurred by the Protected Partner or an Indirect Owner as a result of the income
or gain allocated to, or otherwise recognized by, such Protected Partner with respect to its Units by reason of such breach; 

  

	 	(b)	in the case of a violation of Article 2, the aggregate federal state, and local income taxes incurred by the Protected Partner or an Indirect Owner with respect the Excess Protected
Gain incurred with respect to the Gain Limitation Property that is allocable to such Protected Partner under the Partnership Agreement and Section 2.3 hereof (computed without regard to the principles set forth in the parenthetical in the first
paragraph of Section 2.1); 

 plus in the case of either (a) or (b), an amount equal to the aggregate federal, state,
and local income taxes payable by the Protected Partner or an Indirect Owner as a result of the receipt of any payment required under this Section 4.1. 
 For purposes of computing the amount of federal, state, and local income taxes required to be paid by a Protected Partner (or Indirect Owner), (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 (or Indirect Owner’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 (or Indirect Owner’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 (or Indirect Owner) 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 (or Indirect Owner) to offset other income, gain or taxes of the Protected Partner (or Indirect Owner), either in the current year, in earlier years, or in later years). 
 4.2 Process for Determining Damages. If the Partnership has breached or violated any of the covenants set forth in Article 2, Article 3, or
Article 6 (or a Protected Partner asserts that the Partnership has breached or violated any of the covenants set forth in Article 2, Article 3, or Article 6), the 

  

 F-12 

 
Partnership and the Protected Partner (or Indirect Owner) agree to negotiate in good faith to resolve any disagreements regarding any such breach or
violation and the amount of damages, if any, payable to such Protected Partner (or Indirect Owner) under Section 4.1 (and to the extent applicable, Sections 4.4). If any such disagreement cannot be resolved by the Partnership and such Protected
Partner (or Indirect Owner) within sixty (60) days after the receipt of notice from the Partnership of such breach and the amount of income to be recognized by reason thereof (or, if applicable, receipt by the Partnership of an assertion by a
Protected Partner that the Partnership has breached or violated any of the covenants set forth in Article 2, Article 3, or Article 6), the Partnership and the Protected Partner shall jointly retain a nationally recognized independent 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 breach of any of the covenants set forth Article 2,
Article 3, or Article 6, has occurred and, if so, the amount of 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 the resolution of any breach or violation of any of the covenants set forth in Article 2, Article 3, or Article 6 and the amount of 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 more than five percent (5%) less 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. 
 4.3 Required Notices; Time for Payment. In the event that there has been a breach of Article 2, Article 3, or Article 6 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 7.3 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 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 2.1(b)(ii), 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 2.1(b)(ii), Section 3.2, and/or Sections 3.3 (i) and/or (ii) and a Protected Partner (or Indirect Owner) 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 (or Indirect Owner) an amount equal to the sum
of (i) the Excess Payment plus (ii) the 

  

 F-13 

 
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 (or
Indirect Owner) 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 (or Indirect Owner)
(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 with respect to the properties contributed to the Partnership in connection with the initial public offering of the REIT’s shares of common stock. 
 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 Protected 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 Guaranteed Amount, 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 Forms K-1, provided to partners in the Partnership and returns
of Subsidiaries of the Partnership) or any dealings involving the Internal Revenue Service (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). 
 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 that it may not be more likely than not that such allocations will be respected; provided that the Partnership shall provide to each Protected Partner (or in the event of their death or disability, their executor,
guardian or custodian, as applicable), notice of such determination and if, within forty-five (45) days after the receipt thereof, the Partnership is provided an opinion of a law firm recognized as expert in such matters or a nationally
recognized public accounting firm to the effect that it is more likely than not that such allocations will be respected, the Partnership shall continue to make allocations of Guaranteed Debt or other recourse debt of the Partnership to the Protected
Partners as set forth in this Agreement; provided further that if there shall have been a judicial determination in a proceeding to which the Partnership is a party and as to which the General Partners 

  

 F-14 

 
have been allowed to participate as and to the extent contemplated in Article 6 to the effect that such allocations are not correct, Section 6.1 shall
not apply unless the matter is being appealed to an applicable court of appeals, the requirements of Section 7.2 shall have been satisfied in connection therewith, and the opinion described above from counsel or accountants engaged by a
Protected Partner shall have been provided. In no event shall this Section 6.2 be construed to relieve the Partnership for 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 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. 
 ARTICLE 7 
 TAX PROCEEDINGS 
 7.1 Notice of Tax Audits. If any claim, demand, assessment (including a notice of proposed assessment) or other assertion is made with respect to
taxes against the Protected Partners or the Partnership the calculation of which involves a matter covered in this Agreement that could result in tax liability to a Protected Partner (“Tax Claim”) or if the REIT or the Partnership receives
any notice from any jurisdiction with respect to any current or future audit, examination, investigation or other proceeding (“Tax Proceeding”) involving the Protected Partners or the Partnership or that otherwise could involve a matter
covered in this Agreement and would reasonably be expected to directly or indirectly affect the Protected Partners in an adverse manner, then the REIT or the Partnership, as applicable shall promptly notify the Protected Partners of such Tax Claim
or Tax Proceeding. 
 7.2 Control of Tax Proceedings. The REIT, as the general partner of the Partnership shall have the right to
control the defense, settlement or compromise of any Proceeding or Tax Claim; provided, however, that the REIT shall not consent to the entry of any judgment or enter into any settlement with respect to such Tax Claim or Tax Proceeding
that would result in tax liability to one or more Protected Partners without the prior written consent of the affected Protected Partners (unless, and only to the extent, that any taxes required to be paid by the Protected Partners as a result
thereof would be required to be reimbursed by the Partnership and the REIT under Article 4 and the Partnership and the REIT agree in connection with such settlement or consent, to make such required payments); provided further that the
Partnership shall keep the Protected Partners informed of the progress thereof to the extent that such Proceeding or Tax Claim would reasonably be expected to directly or indirectly affect the Protected Partners in an adverse manner. 
 7.3 Timing of Tax Returns; Periodic Tax Information. The Partnership shall cause to be delivered to each Protected Partner, as soon as reasonably
practicable each year, the Forms K-1 that the Partnership is required to deliver to such Protected Partners with respect to the prior taxable year. In addition, the Partnership agrees to provide to the Protected Partners, upon request, an estimate
of the taxable income expected to be allocable for a specified taxable year from the Partnership to each Protected Partner and the entities that they control, provided that such estimates shall not be required to be provided more frequently
than once each calendar quarter. 
  

 F-15

 AMENDMENT OF THIS AGREEMENT; WAIVER OF CERTAIN PROVISIONS; APPROVAL 
 OF CERTAIN TRANSACTIONS

 8.2 Waiver. Notwithstanding the foregoing, upon written request by the Partnership, each Protected Partner, in its sole discretion, may waive the

conditions of this Agreement. 
 9.2 Assignment. No party hereto shall assign its or his rights or obligations under this Agreement,

substantially all of the assets of either the REIT or the Partnership (or any prior successor thereto as set forth in the preceding portion of this sentence), provided that none of the foregoing shall result in the release of liability of the
REIT and the Partnership hereunder. The REIT and the Partnership covenant with and for the benefit of the Protected Partners not to undertake any transfer of all or substantially all of the assets of either entity (whether by merger, transfer,
spin-off or otherwise) unless the transferee has acknowledged in writing and agreed in writing to be bound by this Agreement, provided that the foregoing shall not be deemed to permit any transaction otherwise prohibited by this Agreement.
