ARTICLE II 
 TAX
MATTERS 
 Section 2.1 Taxable Transfers. 

(a) Unless the Operating Partnership receives the Approval of Gibralt with respect to a Property Indemnification Period Transfer, during the
Property Indemnification Period, the Operating Partnership shall indemnify the Protected Partners as set forth in Section 2.2 if the Operating Partnership or any entity in which the Operating Partnership holds a direct or indirect
interest shall cause or permit (i) any Transfer of all or any portion of a Protected Property (including any interest therein or in the entity owning, directly or indirectly, the Protected 

  
 - 6 - 

 
Property) in a transaction that would result in the recognition of taxable income or gain by any Protected Partner under Section 704(c) of the Code, or (ii) any Fundamental Transaction
that would result in the recognition of taxable income or gain to any Protected Partner (such a Fundamental Transaction and such a Transfer, collectively a “Property Indemnification Period Transfer”). 

(b) Section 2.1(a) shall not apply to any Property Indemnification Period Transfer of a Protected Property (including any interest
therein or in the entity owning, directly or indirectly, the Protected Property): (i) in a transaction in which no gain is required to be recognized by a Protected Partner (an “Exchange”), including a transaction qualifying
under Section 1031 or Section 721 (or any successor statutes) of the Code; provided, however, that any property acquired by the Operating Partnership in the Exchange shall remain subject to the provisions of this Article
II in place of the exchanged Protected Property for the remainder of the Property Indemnification Period; (ii) as a result of the condemnation or other taking of any Protected Property by a governmental entity in an eminent domain
proceeding or otherwise, provided that the Operating Partnership shall use commercially reasonable efforts to structure such disposition as either a tax-free like-kind exchange under Section 1031 or a tax-free reinvestment of proceeds under
Section 1033, but in no event shall the Operating Partnership be obligated to acquire or invest in any property that it otherwise would not have acquired or invested in. 

(c) For any Transfer of all or any portion of any property of the Operating Partnership which is not a Property Indemnification Period
Transfer, the Operating Partnership shall use commercially reasonable efforts to cooperate with the Protected Partners to minimize any taxes payable by the Protected Partners in connection with any such Transfers. 

Section 2.2 Indemnification for Transfers. 

(a) In the event of a Property Indemnification Period Transfer described in Section 2.1(a), the Operating Partnership shall pay to
Gibralt within 30 days after the closing of such Property Indemnification Period Transfer an amount of cash equal to the estimated Make Whole Amount applicable to such Property Indemnification Period Transfer for all Protected Partners affected by
the Property Indemnification Period Transfer. If it is later determined that the true Make Whole Amount applicable to a Protected Partner exceeds the estimated Make Whole Amount applicable to such Protected Partner, then the Operating Partnership
shall pay such excess to Gibralt for the benefit of such Protected Partner within 90 days after the closing of the Property Indemnification Period Transfer, and if such estimated Make Whole Amount exceeds the true Make Whole Amount, then Gibralt
shall promptly refund such excess to the Operating Partnership, but only to the extent such excess was actually received by Gibralt. 
 (b)
Notwithstanding any provision of this Agreement to the contrary, the sole and exclusive rights and remedies of any Protected Partner under Section 2.1(a) shall be a claim against the Operating Partnership for the Make Whole Amount as set
forth in this Section 2.2, and no Protected Partner shall be entitled to pursue a claim for specific performance of the covenants set forth in Section 2.1(a) or bring a claim against any person that acquires a Protected
Property from the Operating Partnership in violation of Section 2.1(a). 

  
 - 7 - 

 (c) For the avoidance of doubt, a vote in favor of a Property Indemnification Period Transfer by
a Protected Partner in its capacity as an owner of OP Units or shares of the REIT shall not constitute a waiver of such Protected Partner’s right to indemnification pursuant to this Section 2.2 as a result of such Property
Indemnification Period Transfer. 
 Section 2.3 Section 704(c) Gain. A good faith estimate of the initial amount of
Section 704(c) gain as of the Closing Date of the Formation Transactions is set forth on Exhibit A hereto. The parties acknowledge that the initial amount of such Section 704(c) gain may be adjusted over time as required by
Section 704(c) of the Code and the Regulations promulgated thereunder. 
 Section 2.4 Approved Liability Maintenance and
Allocation. 
 (a) During the Guaranty Indemnification Period, the Operating Partnership shall: (i) maintain on a continuous basis
an amount of Qualifying Liabilities at least equal to the aggregate Required Liability Amount of all Protected Partners and Other Protected Persons; and (ii) provide to Gibralt, promptly upon request, with a description of the nature and amount
of any Approved Liabilities that are available to be guaranteed by the Protected Partners pursuant to Section 2.4(b) of this Agreement. 

(b) (i) During the Guaranty Indemnification Period, the Operating Partnership shall provide each Protected Partner with the opportunity to
execute a guaranty in a form and manner that receives the Approval of Gibralt of one or more Approved Liabilities in an amount up to such Protected Partner’s Required Liability Amount (each such opportunity and each opportunity required by
Section 2.4(c), a “Guaranty Opportunity”), and (ii) after the Guaranty Indemnification Period, the Operating Partnership shall use commercially reasonable efforts to make Guaranty Opportunities available to each
Protected Partner, provided that in the case of this clause (ii), the Operating Partnership shall not be required to incur any indebtedness that it would not otherwise have incurred, as determined by the Operating Partnership in its reasonable
discretion; provided, however, that in the case of clauses (i) and (ii) the aggregate amount of all guarantees required to be made available by the Operating Partnership for execution by all Protected Partners need not exceed the
aggregate Required Liability Amount of all Protected Partners. The Operating Partnership shall have the discretion to identify the Approved Liability or Approved Liabilities that shall be made available for guaranty by each Protected Partner. Each
Protected Partner may allocate the Guaranty Opportunity afforded to such Protected Partner in any manner determined to be desirable by the Protected Partner. The Operating Partnership agrees to file its tax returns allocating any debt subject to a
Guaranty to the applicable Protected Partners. Each Protected Partner shall bear the costs incurred by it in connection with the execution of any guaranty to which it is a party. To the extent a Protected Partner executes a guaranty, the Operating
Partnership shall deliver a copy of such guaranty to the lender under the Guaranteed Liability promptly after receiving such copy from the relevant Protected Partner. 

(c) During the Guaranty Indemnification Period, the Operating Partnership shall not allow a Debt Notification Event to occur unless the
Operating Partnership provides at least thirty (30) days’ written notice (a “Section 2.4 Notice”) to Gibralt. The Section 2.4 Notice shall describe the Debt Notification Event and designate one or more Approved
Liabilities that may be guaranteed by the Protected Partners pursuant to Section 2.4(b) of this Agreement in an amount 

  
 - 8 - 

 
equal to the amount of the refinanced or repaid Approved Liability that was guaranteed by such Protected Partner immediately prior to the date of the Debt Notification Event. The Section 2.4
Notice shall be deemed to have been provided when delivered in person or when sent by first class United States mail or by other means of written or electronic communication (including by telecopy, facsimile, electronic mail or commercial courier
service) to Gibralt at the address set forth in the Register (as defined in the OP Agreement). Any Protected Partner that desires to execute a guaranty following the receipt of a Section 2.4 Notice by Gibralt shall provide the Operating
Partnership with notice thereof within ten (10) days after the date of the Section 2.4 Notice. 
 (d) Provided the Operating
Partnership satisfies its obligations under Section 2.4(a), (b) and (c) of this Agreement, the Operating Partnership shall have no liability to a Protected Partner under Section 2.4(e) for breach of
Section 2.4, whether or not such Protected Partner timely accepts its Guaranty Opportunity. Furthermore, the Operating Partnership makes no representation or warranty to any Protected Partner concerning the treatment or effect of any
guaranty under Federal, state, local, or foreign tax law, and bears no responsibility for any tax liability of any Protected Partner or Affiliate thereof that is attributable to a reallocation, by a taxing authority, of debt subject to a guaranty
(other than a reallocation that results from any act or omission taken by the Operating Partnership or one of its Affiliates in violation of this Section 2.4 or an act or omission that is indemnifiable under Section 2.4(e) of
this Agreement). 
 (e) If the Operating Partnership shall fail to comply with any provision of this Section 2.4, the Operating
Partnership shall pay, within thirty (30) days of such failure, a Make Whole Payment with respect to each Protected Partner who recognizes income or gain as a result of such failure equal to the estimated Make Whole Amount applicable to such
failure. Such payment shall be made to Gibralt on behalf of such Protected Partner. If it is determined that the true Make Whole Amount applicable to a Protected Partner exceeds the estimated Make Whole Amount applicable to such Protected Partner,
then the Operating Partnership shall pay such excess to Gibralt, on behalf of such Protected Partner, within thirty (30) days after the date of such determination, and if such estimated Make Whole Amount exceeds the true Make Whole Amount, then
Gibralt shall pay such excess to the Operating Partnership within thirty (30) days after the date of such determination, but only to the extent such excess was actually received. 

(f) Notwithstanding any provision of this Agreement to the contrary, the sole and exclusive rights and remedies of any Protected Partner for a
breach or violation of the covenants set forth in Section 2.4 shall be a claim a claim against the Operating Partnership for the Make Whole Amount as set forth in Section 2.4(e), and no Protected Partner shall be entitled to
pursue a claim for specific performance of the covenants set forth in Section 2.4. 
 ARTICLE III

 TAX
MATTERS 
 Section 2.1 Taxable Transfers. 

(a) Unless the Operating Partnership receives the Approval of both CIO OP and Second City GP with respect to a Property Indemnification Period
Transfer, during the Property Indemnification Period, the Operating Partnership shall indemnify the Protected Partners as set forth in Section 2.2 if the Operating Partnership or any entity in which the

  
 - 6 - 

 
Operating Partnership holds a direct or indirect interest shall cause or permit (i) any Transfer of all or any portion of a Protected Property (including any interest therein or in the
entity owning, directly or indirectly, the Protected Property) in a transaction that would result in the recognition of taxable income or gain by any Protected Partner under Section 704(c) of the Code, or (ii) any Fundamental Transaction
that would result in the recognition of taxable income or gain to any Protected Partner (such a Fundamental Transaction and such a Transfer, collectively a “Property Indemnification Period Transfer”). 

(b) Section 2.1(a) shall not apply to any Property Indemnification Period Transfer of a Protected Property (including any interest
therein or in the entity owning, directly or indirectly, the Protected Property): (i) in a transaction in which no gain is required to be recognized by a Protected Partner (an “Exchange”), including a transaction qualifying
under Section 1031 or Section 721 (or any successor statutes) of the Code; provided, however, that any property acquired by the Operating Partnership in the Exchange shall remain subject to the provisions of this Article
II in place of the exchanged Protected Property for the remainder of the Property Indemnification Period; (ii) as a result of the condemnation or other taking of any Protected Property by a governmental entity in an eminent domain
proceeding or otherwise, provided that the Operating Partnership shall use commercially reasonable efforts to structure such disposition as either a tax-free like-kind exchange under Section 1031 or a tax-free reinvestment of proceeds under
Section 1033, but in no event shall the Operating Partnership be obligated to acquire or invest in any property that it otherwise would not have acquired or invested in. 

(c) For any Transfer of all or any portion of any property of the Operating Partnership which is not a Property Indemnification Period
Transfer, the Operating Partnership shall use commercially reasonable efforts to cooperate with the Protected Partners to minimize any taxes payable by the Protected Partners in connection with any such Transfers. 

Section 2.2 Indemnification for Transfers. 

(a) In the event of a Property Indemnification Period Transfer described in Section 2.1(a), the Operating Partnership shall pay to
CIO OP and Second City GP within 30 days after the closing of such Property Indemnification Period Transfer an amount of cash equal to the estimated Make Whole Amount applicable to such Property Indemnification Period Transfer for all Protected
Partners affected by the Property Indemnification Period Transfer. If it is later determined that the true Make Whole Amount applicable to a Protected Partner exceeds the estimated Make Whole Amount applicable to such Protected Partner, then the
Operating Partnership shall pay such excess to CIO OP and Second City GP for the benefit of such Protected Partner within 90 days after the closing of the Property Indemnification Period Transfer, and if such estimated Make Whole Amount exceeds the
true Make Whole Amount, then CIO OP and Second City GP shall promptly refund such excess to the Operating Partnership, but only to the extent such excess was actually received by CIO OP and Second City GP. 

(b) Notwithstanding any provision of this Agreement to the contrary, the sole and exclusive rights and remedies of any Protected Partner under
Section 2.1(a) shall be a claim against the Operating Partnership for the Make Whole Amount as set forth in this Section 2.2, and no Protected Partner shall be entitled to pursue a claim for specific performance of the
covenants set forth in Section 2.1(a) or bring a claim against any person that acquires a Protected Property from the Operating Partnership in violation of Section 2.1(a). 

  
 - 7 - 

 (c) For the avoidance of doubt, a vote in favor of a Property Indemnification Period Transfer by
a Protected Partner in its capacity as an owner of OP Units or shares of the REIT shall not constitute a waiver of such Protected Partner’s right to indemnification pursuant to this Section 2.2 as a result of such Property
Indemnification Period Transfer. 
 Section 2.3 Section 704(c) Gain. A good faith estimate of the initial amount of
Section 704(c) gain as of the Closing Date of the Formation Transactions is set forth on Exhibit A hereto. The parties acknowledge that the initial amount of such Section 704(c) gain may be adjusted over time as required by
Section 704(c) of the Code and the Regulations promulgated thereunder. 
 Section 2.4 Approved Liability Maintenance and
Allocation. 
 (a) During the Guaranty Indemnification Period, the Operating Partnership shall: (i) maintain on a continuous basis
an amount of Qualifying Liabilities at least equal to the aggregate Required Liability Amount of all Protected Partners and Other Protected Persons; and (ii) provide to CIO OP and Second City GP, promptly upon request, with a description of the
nature and amount of any Approved Liabilities that are available to be guaranteed by the Protected Partners pursuant to Section 2.4(b) of this Agreement. 

(b) (i) During the Guaranty Indemnification Period, the Operating Partnership shall provide each Protected Partner with the opportunity to
execute a guaranty in a form and manner that receives the Approval of CIO OP and Second City GP of one or more Approved Liabilities in an amount up to such Protected Partner’s Required Liability Amount (each such opportunity and each
opportunity required by Section 2.4(c), a “Guaranty Opportunity”), and (ii) after the Guaranty Indemnification Period, the Operating Partnership shall use commercially reasonable efforts to make Guaranty
Opportunities available to each Protected Partner, provided that in the case of this clause (ii), the Operating Partnership shall not be required to incur any indebtedness that it would not otherwise have incurred, as determined by the Operating
Partnership in its reasonable discretion; provided, however, that in the case of clauses (i) and (ii) the aggregate amount of all guarantees required to be made available by the Operating Partnership for execution by all Protected
Partners need not exceed the aggregate Required Liability Amount of all Protected Partners. The Operating Partnership shall have the discretion to identify the Approved Liability or Approved Liabilities that shall be made available for guaranty by
each Protected Partner. Each Protected Partner may allocate the Guaranty Opportunity afforded to such Protected Partner in any manner determined to be desirable by the Protected Partner. The Operating Partnership agrees to file its tax returns
allocating any debt subject to a Guaranty to the applicable Protected Partners. Each Protected Partner shall bear the costs incurred by it in connection with the execution of any guaranty to which it is a party. To the extent a Protected Partner
executes a guaranty, the Operating Partnership shall deliver a copy of such guaranty to the lender under the Guaranteed Liability promptly after receiving such copy from the relevant Protected Partner. 

  
 - 8 - 

 (c) During the Guaranty Indemnification Period, the Operating Partnership shall not allow a Debt
Notification Event to occur unless the Operating Partnership provides at least thirty (30) days’ written notice (a “Section 2.4 Notice”) to CIO OP and Second City GP. The Section 2.4 Notice shall describe the Debt
Notification Event and designate one or more Approved Liabilities that may be guaranteed by the Protected Partners pursuant to Section 2.4(b) of this Agreement in an amount equal to the amount of the refinanced or repaid Approved
Liability that was guaranteed by such Protected Partner immediately prior to the date of the Debt Notification Event. The Section 2.4 Notice shall be deemed to have been provided when delivered in person or when sent by first class United
States mail or by other means of written or electronic communication (including by telecopy, facsimile, electronic mail or commercial courier service) to CIO OP and Second City GP at the address set forth in the Register (as defined in the OP
Agreement). Any Protected Partner that desires to execute a guaranty following the receipt of a Section 2.4 Notice by CIO OP and Second City GP shall provide the Operating Partnership with notice thereof within ten (10) days after the date
of the Section 2.4 Notice. 
 (d) Provided the Operating Partnership satisfies its obligations under Section 2.4(a),
(b) and (c) of this Agreement, the Operating Partnership shall have no liability to a Protected Partner under Section 2.4(e) for breach of Section 2.4, whether or not such Protected Partner timely
accepts its Guaranty Opportunity. Furthermore, the Operating Partnership makes no representation or warranty to any Protected Partner concerning the treatment or effect of any guaranty under Federal, state, local, or foreign tax law, and bears no
responsibility for any tax liability of any Protected Partner or Affiliate thereof that is attributable to a reallocation, by a taxing authority, of debt subject to a guaranty (other than a reallocation that results from any act or omission taken by
the Operating Partnership or one of its Affiliates in violation of this Section 2.4 or an act or omission that is indemnifiable under Section 2.4(e) of this Agreement). 

(e) If the Operating Partnership shall fail to comply with any provision of this Section 2.4, the Operating Partnership shall pay,
within thirty (30) days of such failure, a Make Whole Payment with respect to each Protected Partner who recognizes income or gain as a result of such failure equal to the estimated Make Whole Amount applicable to such failure. Such payment
shall be made to CIO OP and Second City GP on behalf of such Protected Partner. If it is determined that the true Make Whole Amount applicable to a Protected Partner exceeds the estimated Make Whole Amount applicable to such Protected Partner,
then the Operating Partnership shall pay such excess to CIO OP and Second City GP, on behalf of such Protected Partner, within thirty (30) days after the date of such determination, and if such estimated Make Whole Amount exceeds the true Make
Whole Amount, then CIO OP and Second City GP shall pay such excess to the Operating Partnership within thirty (30) days after the date of such determination, but only to the extent such excess was actually received. 

(f) Notwithstanding any provision of this Agreement to the contrary, the sole and exclusive rights and remedies of any Protected Partner for a
breach or violation of the covenants set forth in Section 2.4 shall be a claim a claim against the Operating Partnership for the Make Whole Amount as set forth in Section 2.4(e), and no Protected Partner shall be entitled to
pursue a claim for specific performance of the covenants set forth in Section 2.4.
