 ARTICLE 3 

Title 

Section 3.1. Status of Title. Subject to the terms and provisions of this Agreement, Seller shall sell, convey, assign
and transfer good and marketable title to Seller’s interest in the Property to Purchaser, and Purchaser shall purchase, accept and assume the same, subject only to the Permitted Exceptions. 

Section 3.2. Title Insurance Policy; Objections to Title. 

(a) Purchaser acknowledges and agrees that (i) Purchaser has received from Seller a copy of the Existing Title Policy and the
Existing Survey relating to the Real Property and that Purchaser independently obtained the Pro Forma Policy, (ii) Purchaser or Purchaser’s attorneys have reviewed the Existing Title Policy, the Pro Forma Policy and the Existing Survey and
(iii) Purchaser hereby confirms to Seller that Purchaser has no objections to any title exceptions or survey matters revealed by the Pro Forma Policy. Purchaser hereby waives its right to object to any liens, encumbrances or other title
exceptions appearing on the Pro Forma Policy. In addition, Purchaser shall not be entitled to object to, and shall be deemed to have approved, any liens, encumbrances or other title exceptions (and the same shall be deemed Permitted Exceptions)
(A) which the Title Company is willing to omit as exceptions to title, (B) against or over which the Title Company is willing to provide affirmative insurance satisfactory to Purchaser in its reasonable discretion, or (C) which will
be extinguished upon the transfer of the Property to Purchaser (collectively, the “Non-Objectionable Encumbrances”). 

(b) It is expressly understood that in no event shall Seller be required to bring any action or institute any proceeding, or to otherwise
incur any costs or expenses, in order to cause title to the Property to be in accordance with the terms of this Agreement on the Closing Date and that Purchaser hereby agrees to accept title to the Property subject to the Permitted Exceptions and as
otherwise provided in the Pro Forma Policy. Notwithstanding the foregoing, Seller shall be obligated to remove (i) any mortgage (a “Mortgage”) which affects the Property which was created by Seller except in connection with the
Loan Documents, (ii) all judgment liens and all tax liens due and payable by Seller, and (iii) all mechanics liens affecting the Property, in each case which were voluntarily caused or created by Seller (as opposed to, for example, by a
Tenant) (the items in this clause (iii), collectively, “Monetary Liens”); provided, however, that Seller shall not have the obligation to remove any of such Monetary Liens unless such Monetary Lien is in an
ascertainable, fixed amount, and the cost of removing the same (by bonding or otherwise), together with all other Monetary Liens, shall not exceed an aggregate amount of $10,000,000 (the “Monetary Lien Cap Amount”). The Monetary
Lien Cap Amount excludes any Monetary Liens arising from the Bain Lease Obligations. If Seller is required to remove a Monetary Lien pursuant to the terms of this Agreement, Seller shall be entitled to postpone the Closing for a period of up to
thirty (30) days in order to endeavor to remove such Monetary Lien and to use any portion of the Cash Balance to the extent necessary to remove and satisfy same at Closing or to cause same to be omitted by the Title Company as an exception to
coverage. Notwithstanding the foregoing, if the Title Company is willing to insure over such Mortgage or Monetary Lien by either providing for an indemnity or an escrow, or otherwise, then Seller shall not be required to remove such Mortgage or
Monetary Lien. If a Monetary Lien can be removed (by bonding or otherwise) but Seller elects not to remove it, or cause it to be removed, because the cost of removing the same, or the associated liability to the bonding company, plus the cost of
obtaining the bond, exceeds the Monetary Lien Cap Amount, then Purchaser may, at Purchaser’s sole discretion, either proceed to the Closing and accept a credit against the Purchase Price of up to the Monetary Lien Cap Amount (but without any
other modifications to this Agreement) or terminate this Agreement upon five (5) Business Days (or less if Seller’s election occurs within five (5) Business Days before the Closing) prior written notice and receive a refund of the
Deposit, whereupon the 
  

 - 13 - 








 
parties shall have no further rights or obligations hereunder except for the Effective Date Surviving Obligations. If the cost of removing any Monetary Lien(s), in the aggregate, is less than the
Monetary Lien Cap Amount, Seller shall, at its sole option, either remove such item or give to Purchaser a credit against the Purchase Price in an amount equal to the reasonable cost to remove same (up to the Monetary Lien Cap Amount). 

(c) Reserved. 

(d) In no event shall any lien, encumbrance or other exception arising as a result of any act or omission of Purchaser or anyone acting
on behalf of Purchaser be deemed a title objection. 
 (e) Purchaser agrees to purchase the Property subject to any and all
notes or notices of violations of any Legal Requirement noted in or issued by any governmental authority prior to or, subject to the provisions of this Section 3.2(e), after the Effective Date (individually, a “Violation” and
collectively, “Violations”), and/or any lien, penalty or fine imposed in connection with any of the foregoing, and/or any condition or state of repair or disrepair and/or other matter or thing, whether or not noted, which, if noted,
would result in a Violation being placed on the Property. Seller shall have no duty to remove or comply with or repair or disrepair any condition, matter or thing, relating to a Violation placed on the Property on or prior to the Effective Date. For
any Violation first placed on the Property after the Effective Date (a “Post-Effective Date Violation”), (i) Seller shall remove or comply with or repair any such Post-Effective Date Violation, together with any associated
liens, penalties or fines or other conditions on or prior to Closing, if the cost of such Violation and all other Violations arising after the Effective Date is $1,000,000 or less (the “Violation Cap Amount”) and (ii) if the
cost of such Post-Effective Date Violation and all other Post-Effective Date Violations exceeds the Violation Cap Amount, Seller shall have right, exercisable by written notice to Purchaser delivered within three Business Days after receiving actual
notice of such Post-Effective Date Violation(s) that exceed the Violation Cap Amount, to elect not to remove or comply with or repair any such Post-Effective Date Violations, and if Seller elects to proceed under clause (ii), then Purchaser shall
have the right, by written notice delivered within three Business Days after its receipt of Seller’s election, to either (A) accept the Property subject to all Post-Effective Date Violations and all liens, penalties or fines associated
therewith and accept a credit to the Purchase Price in the amount of the Violation Cap Amount as its sole and exclusive remedy or (B) terminate this Agreement and receive a return of the Deposit, whereupon the parties shall have no further
rights or obligations hereunder except for the Effective Date Surviving Obligations. 
 (f) Purchaser shall obtain at its
expense the Owner’s Policy and endorsements to the Loan Policy referenced in Section 5.1 from the Title Company and agrees that Commonwealth and its affiliates shall have the right to directly co-insure 50% of such policies so long as
(i) Commonwealth and its affiliates agree (A) to match the premium that is being charged by the Title Company for such policies and (B) to match the quality and level of coverage, including any coverage provided by endorsements or
affirmative coverage, that is being provided by the Title Company and (ii) such coverage to be provided by Commonwealth and its affiliates is apportioned among Commonwealth and its affiliates as follows: Commonwealth: (15%), Chicago Title
Insurance (20%) and Fidelity National Title Insurance Company (15%). If one of the Title Company or Commonwealth are unable or unwilling to issue the policies (including with respect to eliminating any exceptions relating to the mezzanine loan
foreclosure) in the form required by this Agreement and subject to the provisions set forth in the preceding sentence but the other is so able and willing, the able and willing title insurer shall be entitled, and Purchaser shall be obligated to
obtain, 100% of the policies from such able and willing title insurer.

prior written consent, which Seller may give or withhold in its absolute discretion, Purchaser shall not conduct any Phase II exams, soil borings, testing or sampling of any surface or subsurface soils or other subsurface conditions, water or other
materials, or other invasive tests on or around the Property. The foregoing shall constitute Surviving Obligations. 

Section 4.2. Confidentiality.

whom it has delivered Confidential Information to disclose the Confidential Information to any Person without, in each instance, Seller’s prior written consent. Purchaser further agrees that, before the Closing, Purchaser will use the

the Confidential Information to any Person, other than (i) as necessary to comply with its obligations under this Agreement to assist Seller in obtaining the Required Consents and (ii) to such of its employees, officers, directors,

of the confidential nature of such information, and (C) have agreed to maintain the confidential nature of such information pursuant to the terms of this Section 4.2. 

(b) Notwithstanding the above terms, to the extent that Purchaser is required to disclose the Confidential Information by law, regulation

Purchaser shall 
  

 - 15 - 








 
cooperate, at no cost to Purchaser, with Seller’s counsel in any appeal or challenge to such disclosure made by Seller. If no protective order or similar relief is obtained, Purchaser shall

(iii) exercise reasonable efforts to provide Seller with a copy of the information to be disclosed before the same is given to any third party. In addition, and notwithstanding anything to the contrary in this Agreement, Purchaser may disclose
any portion of the Confidential Information that is generally available to the public, other than any portion of the Confidential Information that becomes available to the public as a result of a previous disclosure by Purchaser in violation of this
Agreement. 
 (c) If this Agreement is terminated, (i) Purchaser shall promptly deliver to Seller all the Confidential
Information (or portions thereof requested by Seller) which is in tangible form, including any copies Purchaser has made and other embodiments thereof, and (ii) Purchaser shall destroy all extracts, summaries and compilations thereof and

information and belief, it has done so. 
 (d) Purchaser acknowledges that the Confidential Information is of a special, unique,
unusual, extraordinary and intellectual character and that Seller’s interest in the Confidential Information may be irreparably injured by disclosure of such Confidential Information in violation of this Agreement. Purchaser further
acknowledges and agrees that money damages would not be a sufficient remedy for any breach of Section 4.2 of this Agreement by it and that, in addition to all other remedies available at law or in equity, Seller shall be entitled to
specific performance or injunctive or other equitable relief as a remedy for any breach or potential breach by Purchaser of Section 4.2 of this Agreement and further agrees to waive any requirement for the securing or posting of any bond
in connection with such remedy. Notwithstanding the foregoing, in no event shall Purchaser have any liability for indirect, consequential or punitive damages. 

(e) Except as provided otherwise in this Section 4.2, Purchaser and Seller, for the benefit of each other, hereby agree that
neither of them will release or cause or permit to be released to the public (which each party agrees does not include the direct or indirect partners or prospective investors in each of the funds that indirectly own Seller) any press notices,
publicity (oral or written) or advertising promotion relating to, or otherwise publicly announce or disclose or cause or permit to be publicly announced or disclosed, in any manner whatsoever, the names of Seller and Purchaser respectively, or any
of their affiliates or subsidiaries, the terms, conditions or substance of this Agreement or the transactions contemplated herein, without first obtaining the consent of the other party hereto, which shall not be unreasonably withheld. Seller, being
aware that the securities of Boston Properties, Inc. (“BPI”), the owner, directly or indirectly, of a controlling interest in Purchaser, are traded on the New York Stock Exchange, acknowledges that Purchaser and BPI may be compelled

counsel to such other party or (ii) which is necessary to comply with a party’s obligations under this Agreement including, without limitation, in connection with obtaining the Required Consents. In addition, Purchaser and BPI. shall have
the right to attach a copy of this Agreement as an exhibit to one or more of their respective required filings with the Securities and Exchange Commission on Form 8-K or Form 10-Q and to

violation by Purchaser of the terms of this Agreement or the confidentiality agreement that is referred to herein. 
 (f) The
provisions of this Section 4.2 shall supersede all prior confidentiality agreements between Purchaser and Seller and shall survive for a period of six (6) months from the earlier of the Closing Date and any termination of this
Agreement. 
 Section 4.3. Reporting. In the event that Purchaser’s due diligence reveals any condition
of the Property that in Purchaser’s judgment requires disclosure to any governmental agency or authority, Purchaser shall immediately notify Seller thereof. In such event, Seller, and not Purchaser or anyone acting on Purchaser’s behalf,
shall make such disclosures as Seller deems appropriate. Notwithstanding the foregoing, to the extent that Purchaser is required to disclose the discovered condition by law, regulation or stock exchange rule or pursuant to a subpoena, court order or
other legal proceeding, Purchaser may do so but shall first notify Seller (both by telephone and in writing) within two (2) Business Days of its actual knowledge of such legally required disclosure. 

Section 4.4. Estoppels. From and after the Effective Date, Seller shall request and endeavor to obtain from each
Tenant and from the parties to the Declaration and to the Hancock License Agreement an estoppel certificate, in forms required by the applicable Leases or such documents or otherwise as mutually and reasonably agreed to between Seller and Purchaser.
Notwithstanding such request, (a) the receipt of one or more estoppel certificates shall not be a condition precedent to Purchaser’s performance under this Agreement, (b) no claim by any Tenant or other party disclosed on a returned
estoppel certificate shall give rise to any liability of Seller under this Agreement or otherwise or excuse Purchaser’s performance under this Agreement (except as provided below in this Section 4.4) and (c) Seller shall have
absolutely no liability under this Agreement or otherwise to obtain any estoppel certificates. If an estoppel is received by Seller or Purchaser (including after the Closing Date), the matters certified to by the Tenant or the other party delivering
such estoppel (the “Estoppel Matters”) shall, with respect to the Seller Representations covered by such Estoppel Matters, have the following effect: (i) to the extent the Estoppel Matters confirm the Seller Representations,
the Estoppel Matters shall be removed from the related Seller Representations from and after the date of Purchaser’s receipt of the related estoppel and (ii) to the extent the Estoppel Matters allege matters that would, if true, result in
a breach of the Seller Representations, such Estoppel Matters shall not remove the related Seller Representations and, to the extent that a breach does in fact exist, the parties shall have available the rights and remedies with respect thereto as
set forth in Article 9.

subject to the provisions set forth in (d) below: 
 (a) Seller shall have performed and complied in all material
respects with all of the terms of this Agreement to be performed and complied with by Seller prior to or at the Closing.

Section 5.7. If Seller shall not have obtained and delivered to Purchaser copies of the Required Consents that satisfy the requirements of Section 5.7 on or before the 120th day after the Effective Date: 

(i) either Purchaser or Seller shall have the right (in its sole discretion), exercisable by written notice to the other party on or
before such 120th day, to extend the Closing Date for up to 60 additional days to provide additional time to obtain the Required Consents (such 120th day or, if extended by 60 days as provided above, such 180th day after the Effective Date, the
“Outside Consent Date”); 
 (ii) Purchaser shall have the right, with respect to the Lender Consent, to waive
the Lender Consent as a condition to Closing by delivering written notice to Seller of such waiver, which written notice shall constitute an irrevocable election (the “Defeasance Election”) by Purchaser to (A) cause Seller to
defease the Existing Loan in accordance with the Loan Documents and in compliance with the provisions of the Loan Documents, (B) waive any further right to assume the Existing Loan, (C) pay to Existing Lender, or reimburse Seller at

attorneys’ fees, recording fees, accounting fees, the cost of purchasing United States treasuries or other defeasance collateral, any incremental increase in Transfer Taxes caused by the fact that the Existing Loan is not being assumed,
underwriting fees and rating agency fees, in addition to all Loan Transfer Fees that have been incurred in connection with the previously requested assumption of the Existing Loan and (D) take such actions as it shall be required to take to

 (iii) Purchaser shall have the
right, with respect to the Ground Lessor Consent, to waive the Ground Lessor Consent as a condition to Closing by written notice to Seller of such waiver (the “Ground Lessor Waiver Election”), provided that (A) Purchaser meets
the Tangible Net Worth test referenced in Section 5.7(b) and otherwise delivers to Seller and/or Ground Lessor evidence sufficient to confirm that Purchaser satisfies the applicable requirements of the Ground Lease that permit the Ground Lease
to be transferred without Ground Lessor Consent, (B) the Ground Lease Waiver Election shall be deemed to be a waiver by Purchaser of any obligation on the part of Seller to deliver to Purchaser the Ground Lease estoppel and shall relieve Seller
of any and all obligations to make any representations, warranties or indemnities with respect to the Ground Lease other than the representation and warranty set forth in Section 6.2(bb), which shall continue in all events, and
(C) Purchaser shall continue to be responsible for all Ground Lessor Consent Fees incurred in connection with the previously requested Ground Lessor Consent or satisfaction of the requirements necessary to relieve Seller’s obligation to
obtain the Ground Lessor Consent. 
 (e) Seller shall have caused the Lobby Work, the Cafe Work, the Landlord’s Initial
Work and the Other Seller Work to have been Substantially Completed; provided, however, that to the extent (if any) that any remaining part of such work has not been Completed prior to Closing, Seller shall either (i) diligently perform such
work to Completion as soon as practicable after the Closing in the 
  

 - 18 - 








 
manner applicable to Seller’s performance of the Seller’s Work after Closing under Article 8 (and the provisions of Article 8 shall apply thereto mutatis mutandis) or
(ii) at Closing, credit the cost of such remaining work (in an amount mutually agreed by the parties) against the Purchase Price. 

(f) Title Company shall be irrevocably obligated to issue an ALTA Owner’s Policy of Title Insurance to Purchaser in the form of the

 (h) Purchaser
shall have received confirmation from Escrow Agent that it continues to hold the Fund Guaranty and that Escrow Agent is unconditionally committed to deliver the Fund Guaranty to or at the direction of Purchaser at Closing. 

Purchaser acknowledges and agrees that its obligation to perform under this Agreement is not contingent upon Purchaser’s ability to
obtain any (i) governmental or quasi-governmental approval of changes or modifications in use or zoning, or (ii) modification of any existing land use restriction, or (iii) consents to assignments of any service contracts or other
agreements (other than the Required Consents) which Purchaser requests. 
 Section 5.2. Conditions Precedent Favoring
Seller. In addition to any other condition precedent in favor of Seller as may be expressly set forth elsewhere in this Agreement, Seller’s obligation under this Agreement is expressly subject to the timely fulfillment of the conditions
set forth in this Section 5.2 on or before the Closing Date, or such earlier date as is set forth below. Each condition may be waived in whole or part only by written notice of such waiver from Seller to Purchaser. 

(a) Purchaser shall have performed and complied in all material respects with all of the terms of this Agreement to be performed and
complied with by Purchaser prior to or at the Closing; 
 (b) The Purchaser Representations shall be true and correct in all
material respects as of the Closing Date;

accordance with Section 2.2 hereof, and any other amounts due to Seller from Purchaser hereunder, and that Escrow Agent is in possession of written authorization from Purchaser to disburse such funds to or at the direction of Seller at
Closing. 
 Section 5.3. Risk of Loss. 

In the event that, prior to the Closing Date, all or a portion of the Improvements should be damaged or destroyed by fire or other
casualty such that (y) Seller’s reasonable estimate of the cost to repair the same exceeds $100,000,000 or (z) Existing Lender is not obligated to release the insurance proceeds for reconstruction of the Property (it being agreed that
if Existing Lender is obligated to release such proceeds subject to the satisfaction of the requirements for release set forth in Section 7.4 of the Loan Agreement forming part of the Loan Documents, then Existing Lender shall be deemed to be

  

 - 19 - 








 
obligated to release such proceeds for the purposes of this Section 5.3(z)) (any such casualty, a “Material Casualty”), Purchaser may, at Purchaser’s sole
option, elect to either: 
 (a) terminate this Agreement and receive a refund of the Deposit; or 

(b) close the transaction contemplated by this Agreement as provided below. 

In the event of a fire or other casualty that is not a Material Casualty, or if there is a Material Casualty and Purchaser elects to
proceed to Closing pursuant to Section 5.3(b), (i) Purchaser shall purchase the Property in accordance with the terms hereof (without reduction in the Purchase Price other than a credit for any applicable deductible in Seller’s
insurance policy) and (ii) Seller shall assign to Purchaser at Closing all insurance proceeds payable on account of such damage (net of collection costs and costs of repair incurred by Seller and not then reimbursed, which costs shall be
disclosed to Purchaser before it makes its election under this Section 5.3). With respect to any Material Casualty, Purchaser shall be deemed to terminate this Agreement pursuant to Section 5.3(a) unless, within ten
(10) days from receipt of notice of such Material Casualty, Purchaser provides Seller with written notice that Purchaser elects to proceed under Section 5.3(b). 

Section 5.4. Condemnation. In the event that, prior to the Closing Date, all or a material portion of the Real
Property should be condemned by right of eminent domain, such that (y) Seller’s reasonable estimate of the loss of value of the remaining Real Property exceeds $100,000,000 or (z) Existing Lender is not obligated to release the
condemnation proceeds for reconstruction of the Property (it being agreed that if Existing Lender is obligated to release such proceeds subject to the satisfaction of the requirements for release set forth in Section 7.4 of the Loan Agreement
forming part of the Loan Documents, then Existing Lender shall be deemed to be obligated to release such proceeds for the purposes of this Section 5.4(z)) (any such event, a “Material Taking”), Purchaser may, at
Purchaser’s sole option, elect either to: 
 (a) terminate this Agreement and receive a refund of the Deposit; or

 (b) close the transaction contemplated by this Agreement as provided below. 

In the event of a condemnation by right of eminent domain that is not a Material Taking, or if there is a Material Taking and Purchaser
elects to proceed to Closing under Section 5.4(b), Purchaser shall purchase the Property in accordance with the terms hereof (without reduction in the Purchase Price) and Seller shall assign to Purchaser at Closing all condemnation
proceeds payable as a result of such condemnation (net of collection costs and costs of repair reasonably incurred by Seller and not then reimbursed, which costs shall be disclosed to Purchaser before it makes its election under this
Section 5.4). With respect to any Material Taking, Purchaser shall be deemed to have elected to terminate this Agreement pursuant to Section 5.4(a) unless, within ten (10) days from written notice of such Material
Taking, Purchaser provides Seller with written notice that Purchaser elects to proceed under Section 5.4(b). 

Section 5.5. Activities Prior to Closing. Prior to the Closing, Seller shall: 

(a) not sell or further encumber all or any interest in the Property, 

(b) give Purchaser prompt written notice of: 
  

 - 20 - 








 (i) (A) any casualty affecting all or any portion of the Property or (B) any other
event of which other event Seller obtains actual knowledge which is specific to the Real Property and which either (1) constitutes a Material Adverse Effect or (2) Seller is otherwise obligated to notify Purchaser of pursuant to this
Agreement, 
 (ii) any pending or threatened condemnation proceeding or material litigation affecting the Real Property of
which Seller receives actual written notice, 
 (iii) any event or circumstance of which Seller has actual knowledge that makes
any of Seller’s Representations under this Agreement materially untrue or incorrect, 
 (iv) all written notices and other
written correspondence sent by a Seller Party to, or received by a Seller Party from, Existing Lender or Ground Lessor, and 

(v) any other event required for Seller to comply with its obligations under this Section 5.5. 

(c) continue to insure the Property substantially as it is insured as of the Effective Date. 

(d) continue to comply with its obligations under the Loan Documents, Leases (including, without limitation, the administration of tenant
improvement or other work to be performed by the landlord thereunder), Contracts and all other agreements of Seller, including the obligation to pay all Tenant Costs under Leases as and when due under the applicable Leases and other agreements;
provided, however, that to the extent such compliance causes Seller to expend funds for obligations that are Purchaser’s obligation to pay pursuant to this Agreement, such amounts shall be set forth on the Closing Statement and
Seller shall receive a credit to the Purchase Price at Closing for such amounts. Notwithstanding the foregoing, for the sake of clarity, Purchaser acknowledges and agrees that Seller shall not be obligated to perform (i) the CSX rail-side of
the garage façade work (for which Purchaser is receiving a credit at Closing as provided in Section 7.4) or (ii) any drainage or other work that Seller has not expressly agreed to perform pursuant to this Agreement. With respect to
the tenant improvement work performed by the landlord under the Autonomy and Photon leases referenced in Schedule 6.2(l), to the extent the work to be performed by the landlord under either of such leases is not completed prior to Closing, Seller
shall assign the construction contract and related agreements for such work to Purchaser, pursuant to assignment and assumption instruments reasonably acceptable to the parties. 

(e) notify Purchaser and provide Purchaser with copies of any proposed Leases, renewals, terminations or material amendments to Leases
for the Property and obtain the prior written consent of Purchaser (which, in the case of consents to be delivered under clause (iii) below, shall not be unreasonably withheld to the extent such enforcement action is in the ordinary course of
enforcing Leases) before (i) issuing any non-binding proposals for proposed Leases, renewals, terminations or material amendments to Leases for the Property or responding to any such proposals, (ii) entering into any binding agreement or
commitment to effectuate any such transactions or (iii) initiating any enforcement action against any Tenant. 
 (f) notify
Purchaser and provide Purchaser with copies of any proposed billing statements for Tenants with respect to calendar year 2011 and obtain the prior written consent of Purchaser (which shall not be unreasonably withheld, conditioned or delayed) before
issuing such billing statements to the respective Tenants. 
  

 - 21 - 








 (g) send to Purchaser copies of weekly leasing activity reports and any material written
notices sent by a Seller Party to, or received by a Seller Party with respect to, a Tenant, the Property or the Contracts. 

(h) continue to diligently supervise the contractors to ensure the completion of the Lobby Work and the Cafe Work prior to the Closing
Date, and invite and afford Purchaser and/or its representatives the opportunity (where practicable) to participate in all weekly meetings with contractors and otherwise afford Purchaser the opportunity (where practicable) to participate in such
supervision and oversight as reasonably requested by Purchaser. 
 (i) continue to diligently supervise the progression of the
Garage Work, the Chiller Work and the work described in Section 5.1(e) in accordance with Article 8, and invite and afford Purchaser and/or its representatives the opportunity (where practicable) to participate in all weekly meetings
with contractors and otherwise afford Purchaser the opportunity (where practicable) to participate in such supervision and oversight as reasonably requested by Purchaser. 

(j) continue to operate and maintain the Property in substantially the same manner as it has heretofore been operated and maintained by
Seller during the Ownership Period. 
 Section 5.6. Payment of Taxes. 

Seller shall be responsible for and shall pay when due all Taxes (unless otherwise expressly provided in this Agreement) levied with respect to the
operations and/or assets of the Property attributable to any Tax period ending on or before the Closing Date unless such Taxes are being disputed by Seller in good faith in accordance with the Loan Documents and applicable law. 

Section 5.7. Required Consents. 

(a) Existing Loan. Subject to the provisions of this Section 5.7(a), Seller shall diligently and in good faith seek,
and Purchaser shall diligently and in good faith cooperate with Seller and Existing Lender to assist Seller to obtain, the consent (“Lender Consent”) required under the Loan Documents to the transactions contemplated by this
Agreement (the “Contemplated Transactions”). Purchaser and Seller agree to cooperate in good faith to obtain the Lender Consent and Purchaser agrees that Seller shall control the process but shall, in so doing, keep Purchaser and
its counsel regularly informed and (where practicable) regularly involved in the process, including copying Purchaser and its counsel on all written notices delivered to Existing Lender and its counsel, and inviting and affording Purchaser and its
counsel the opportunity to participate in all meetings and conference calls. 
 (i) Purchaser has received and
reviewed the Loan Documents and has made its own independent decision with regard to the nature of the Required Consents required thereby as a result of the Contemplated Transactions and understands and agrees that Existing Lender has discretion to
approve, and could disapprove, the Contemplated Transactions. 
 (ii) On or before the fifth Business Day after
the Effective Date, Seller shall notify Existing Lender of the Contemplated Transactions and request that Existing Lender provide a list of Existing Lender’s requirements (the “Lender Requirements”) for the consummation of the
loan assumption and Lender Consent. Seller’s notification to Existing Lender shall include a copy of this Agreement and a financial statement for the Substitute Guarantor proposed by Purchaser and a structure chart for Purchaser, Substitute
Guarantor and their respective direct and indirect owners. Following such request, Seller and Purchaser, as applicable, shall promptly provide all information required to be delivered to Existing Lender in

  

 - 22 - 








 
connection with obtaining Lender Consent under the Loan Documents (including the proposed organizational documents for Purchaser and its constituent members or partners) and all other information
reasonably requested by Existing Lender. Each of Purchaser and Seller shall use diligent efforts, and shall cooperate with each other and any other Persons (e.g., the Existing Lender, the Ground Lessor and the rating agencies), in order to obtain
Lender Consent as soon as is reasonably possible. Each party shall from time to time upon the other’s reasonable request, provide status updates on the efforts to obtain Lender Consent and each party shall copy the other on all submissions and
material correspondence to and from Existing Lender, including Seller’s submission request letter to Existing Lender. 

(iii) In furtherance of the provisions of this Section 5.7(a): 

(1) Purchaser shall execute and deliver or cause to be delivered to Existing Lender such assumption agreements,
reaffirmation agreements, loan modifications, legal opinions, resolutions, certificates, title insurance endorsements and other instruments and documents as Existing Lender or the rating agencies may require pursuant to the applicable provisions of
the Loan Documents or may otherwise reasonably require in connection with the Lender Consent (collectively, the “Loan Assumption Documents”). In this regard, Purchaser acknowledges that the Existing Loan has been securitized and
that Purchaser shall be obligated to comply with, and it shall be deemed reasonable for Existing Lender or the rating agencies to request that Purchaser comply with, the S&P U.S. CMBS Requirements applicable to the assumption of the Existing
Loan by Purchaser, the structuring of Purchaser and the other requirements applicable to loan assumptions, together with any other customary requirements of lenders, servicers or rating agencies for the assumption of securitized loans, including,
without limitation, the requirement that Purchaser and any direct member of Purchaser be newly-formed SPEs and that, from the Effective Date until the Closing Date, Purchaser (or its assignee) be a wholly-owned direct or indirect subsidiary of
Boston Properties Limited Partnership. Notwithstanding the foregoing, the Loan Assumption Documents shall not impose any obligations on Purchaser’s principals or, subject to any additional burdens or obligations imposed on Purchaser or any of
its affiliates under any express provision of this Section 5.7(a), impose any additional burdens on Purchaser, or any affiliates, not contained in the Loan Documents, nor amend any provision of the Loan Documents in any materially
adverse manner or otherwise materially adversely change the existing terms of the Existing Loan except as may be requested by Purchaser. In connection with the Lender Consent submission, Purchaser shall have the right to request reasonable
modifications to the Existing Loan Documents in order to reflect the change in the identity and ownership structure of the new borrower and the new guarantor, including without limitation, changes to the permitted transfer provisions, the insurance
provisions, the notice provisions, any modifications to the property management agreement, and the right to structure the transaction in accordance with Section 10.22 of this Agreement; provided, however, that (I) the
failure to obtain any such reasonable modifications shall not be deemed a failure of the condition to obtain Lender Consent and if Lender Consent shall be forthcoming without such modifications, then Purchaser shall be required to accept Lender
Consent without such modifications and (II) any obligations imposed on Purchaser or its affiliates in connection with any such modifications agreed to between Purchaser and Existing Lender shall not be considered additional burdens on Purchaser or
its 
  

 - 23 - 








 
affiliates under this Section 5.7(a). Purchaser agrees to reasonably negotiate provisions drafted to incorporate any requested reasonable modifications. In no event shall Purchaser
obtain the Approved Mezzanine Loan (as defined in the Loan Documents) prior to Closing or, prior to Closing, include or have the right to obtain any third party equity, preferred equity investor or pari passu or subordinated lender providing
preferred equity, mezzanine debt or other indebtedness that is not expressly permitted by the Loan Documents in existence as of the Effective Date. 

(2) Seller shall execute and deliver such release of Existing Lender and other documents as may be reasonably requested
by Existing Lender to obtain Lender Consent. 
 (3) Purchaser shall cause a Substitute Guarantor affiliated with
Purchaser to execute and deliver to Existing Lender (I) a guaranty of recourse obligations and an environmental indemnity agreement, (II) an assumption of the tenant’s interest in the 58th Floor Master Lease and (III) a guaranty of the
obligations of the affiliate of the Normandy Fund under that certain ROFO side letter with Existing Lender for any liability of the landlord thereunder from and after the Closing (collectively, the “Existing Guarantees”) in form and
substance substantially similar to the ones that currently are part of the Loan Documents (the “Substitute Guarantees”) and Seller shall seek to obtain from Existing Lender a release of all liability under the Existing Guarantees
from and after (but not before) the assumption of the Existing Loan by Purchaser on the Closing Date (the “Prospective Release”). If Seller is unable to obtain the Prospective Release from Existing Lender (and, in the case of the
58th Floor Master Lease, Existing Lender’s consent to the assignment to Purchaser of Seller’s interest as landlord under the 58th Floor Master Lease, the assumption by Substitute Guarantor of the tenant’s interest in the 58th Floor
Master Lease and the other obligations to assignment and assumption thereof described above (collectively, the “58th Floor Lease Assumption Documents”)), Substitute Guarantor shall execute and deliver to Seller at Closing an
agreement indemnifying the Seller Parties from all claims, liabilities, losses, damages, judgments, costs and expenses, including, but not limited to, reasonable attorneys’ fees and disbursements, arising under the Existing Guarantees that are
attributable to actions occurring on or after the Closing Date (the “Guaranty Indemnification Agreement”). 

(4) If Existing Lender shall fail or refuse to grant Lender Consent on or before the Outside Consent Date for a reason
other than the default by Seller or Purchaser in its obligations under this Agreement and Purchaser has not made the Defeasance Election, this Agreement shall automatically (and without the necessity of notice) terminate, in which case Escrow Agent
shall return the Deposit to Purchaser and neither Seller nor Purchaser shall have any further liability hereunder or by reason hereof except for the Effective Date Surviving Obligations. If the failure to obtain Lender Consent is due to the default
by Seller or Purchaser in its obligations under this Agreement, then the provisions of Article 9 shall apply. 

(5) Seller and Purchaser agree that the Lender Consent shall be deemed given (so that the parties may proceed to
scheduling a Closing) if the 
  

 - 24 - 








 
Contemplated Transactions are permitted, even if such consent is conditioned upon or subject to the execution and delivery of the Substitute Guarantees, Loan Assumption Documents and other
documents and deliveries contemplated by this Section 5.7(a)(iii) on the Closing Date. 
 (iv)
Purchaser shall be obligated to pay to Existing Lender, or reimburse Seller at Closing for, all of the fees, costs and expenses required by the Loan Documents and/or Existing Lender (collectively, the “Loan Transfer Fees”) in
connection with the Lender Consent, whether or not received, including, but not limited to, all processing fees, application fees, attorneys’ fees, recording fees, underwriting fees and rating agency fees. 

(v) At the Closing, Seller shall receive a credit (the “Loan Reserve Credit”) to the Purchase Price for
(A) the then outstanding balance of all reserves, escrows, and/or deposits then being held as of the Closing Date by Existing Lender under the Loan Documents (collectively, the “Loan Reserves”) for real estate taxes, insurance,
deferred maintenance, capital replacements, tenant improvements and leasing commissions, ground rent under the Ground Lease and other purposes (after taking into account any pending requisitions relating thereto so that (1) if the pending
requisition is for a cost for which Seller is responsible under this Agreement, Seller would not receive a credit for such requisition and (2) if the pending requisition is for a cost for which Seller is not responsible under this
Agreement, Seller would receive a credit for such requisition), and (B) any and all other funds derived from the Property held by Existing Lender in any lockbox, cash management or other account or subaccount as of the Closing Date,
subject to adjustment in accordance with the proration provisions specified herein; provided, however, that (1) Seller shall not receive any Loan Reserve Credit for any amounts (i.e., Bain Lease Obligation Security) then being
held by Existing Lender that constitute funds reserved for Seller Retained Obligations, and Seller shall continue to hold title to and have the right to use such amounts as provided in Article 8, and (3) the $7.5 Million LOC shall not
constitute part of the Loan Reserve Credit. 
 (vi) At the Closing, (A) interest under the Existing Loan
shall be prorated between Seller and Purchaser as of the Closing Date with Seller receiving a credit for any prepaid interest and Purchaser receiving a credit for any accrued and unpaid interest as of the Closing Date and (B) Seller shall pay
to Existing Lender all amounts due and owing by Seller to Existing Lender as of the Closing Date. 
 (b) Ground Lessor
Consent. Subject to the provisions of this Section 5.7(b), Seller shall diligently and in good faith seek, and Purchaser shall diligently and in good faith cooperate with Seller and Ground Lessor to assist Seller in obtaining, any
consent (the “Ground Lessor Consent”) of the Ground Lessor required under the Ground Lease to the Contemplated Transactions (the parties agreeing that the agreement of the Ground Lessor to provide the consent set forth in the Ground
Lessor Assignment and Consent shall constitute Ground Lessor Consent and shall be acceptable for this purpose). Purchaser and Seller agree to cooperate in good faith to obtain the Ground Lessor Consent and Purchaser agrees that Seller shall control
the process but shall, in so doing, keep Purchaser and its counsel regularly informed and (where practicable) regularly involved in the process, including copying Purchaser and its counsel on all written notices delivered to Ground Lessor and its
counsel, and inviting Purchaser and its counsel to all meetings and conference calls. 
 (i) On or before the
fifth Business Day after the Effective Date, Seller shall notify Ground Lessor of the Contemplated Transactions and request that Ground Lessor provide the Ground Lessor Consent and, in such notification, (A) Seller shall deliver to Ground
Lessor a copy of this Agreement, and (B) Purchaser shall provide a structure chart for Purchaser, its 
  

 - 25 - 








 
members and their respective direct and indirect owners. Purchaser agrees that, directly or indirectly through a parent guaranty or other credit support given to Ground Lessor in a form
acceptable to Ground Lessor, Purchaser shall have a Tangible Net Worth (as defined in Section 10.1(a) of the Ground Lease) of $50,000,000 or more, shall provide financial statements or other evidence satisfactory to Ground Lessor to establish
such Tangible Net Worth, and shall comply with the other applicable transfer requirements of the Ground Lessor set forth in the Ground Lease. Seller and Purchaser, as applicable, shall promptly deliver all information to be delivered to Ground
Lessor in connection with obtaining the Ground Lessor Consent that is required under the Ground Lease and all other information reasonably requested by Ground Lessor. Each of Purchaser and Seller shall use diligent efforts, and shall cooperate with
each other and any other Persons, in order to obtain the Ground Lessor Consent as soon as is reasonably possible. Each party shall from time to time upon the other’s reasonable request, provide status updates on the efforts to obtain the Ground
Lessor Consent and each party shall copy the other on all submissions and material correspondence to and from Ground Lessor, including Seller’s submission request letter to Ground Lessor. In connection with obtaining the Ground Lessor Consent,
Seller shall request from Ground Lessor and use diligent efforts to obtain an executed estoppel certificate from Ground Lessor in accordance with the terms of the Ground Lease Assignment and Consent. 

(ii) If the Ground Lessor shall fail or refuse to grant the Ground Lessor Consent on or before the Outside Consent Date
for a reason other than the default by Seller or Purchaser in its obligations under this Agreement and Purchaser has not made the Ground Lessor Waiver Election, this Agreement shall automatically (and without the necessity of notice) terminate, in
which case, Escrow Agent shall return the Deposit to Purchaser and neither Seller nor Purchaser shall have any further liability hereunder or by reason hereof except for the Effective Date Surviving Obligations. If the failure to obtain Ground
Lessor Consent is due to the default by Seller or Purchaser in its obligations under this Agreement, then the provisions of Article 9 shall apply. 

(iii) Seller and Purchaser agree that the Ground Lessor Consent shall be deemed given (so that the parties may proceed to
scheduling a Closing) if the Contemplated Transactions are permitted, even if such consent is conditioned upon or subject to the execution and delivery of the Ground Lessor Consent and the other documents and deliveries contemplated by this
Section 5.7(b) on the Closing Date. 
 (iv) Purchaser shall be obligated to pay to the Ground Lessor,
or reimburse Seller at Closing for, all of the costs and expenses required by the Ground Lease and/or the Ground Lessor (collectively, the “Ground Lessor Consent Fees”) in connection with obtaining the Ground Lessor Consent,
including, but not limited to all processing fees, application fees, attorneys’ fees and other out-of-pocket costs and expenses.

Seller, express or implied, including any warranty of income potential, operating expenses, uses, merchantability or fitness for a particular purpose, and Seller does hereby disclaim and renounce any such representation or warranty. Purchaser

 (i) any and all statements or opinions heretofore or hereafter made, or information furnished, by or on behalf
of Seller Parties to Purchaser or any of Purchaser’s agents 
  

 - 27 - 








 
or representatives (other than Seller’s Representations, subject, however, to the limitations and conditions relating thereto set forth in Section 9.4 and elsewhere in this
Agreement); and 
 (ii) any and all losses, costs, claims, liabilities, expenses, demands or obligations of any
kind or nature whatsoever, whether known or unknown and foreseen or unforeseen, attributable to the Property, whether arising or accruing before, on or after the Closing and whether attributable to events or circumstances which have heretofore or
may hereafter occur, including all losses, costs, claims, liabilities, expenses, demands and obligations with respect to the structural, physical, or environmental condition of the Property including claims or liabilities relating to the presence,
discovery or removal of any Hazardous Materials in, at, under or about the Property and any other matters described in Section 6.1(b). Without limiting the foregoing (but subject in all events to the proviso below), Purchaser hereby
agrees that, if at any time after the Closing, any third party or governmental agency seeks to hold Purchaser responsible for the presence of, or any loss, cost or damage associated with, Hazardous Materials in, on, above, adjacent to or beneath the
Real Property or emanating therefrom, then Purchaser waives any rights it may have against Seller in connection therewith, including under CERCLA, and Purchaser agrees that it shall not (1) implead Seller, (2) bring a contribution action
or similar action against Seller or (3) attempt in any way to hold Seller responsible with respect to any such matter; 

provided, however, that the release and waiver set forth in this Section 6.1(c) is not intended and shall not be
construed to affect or impair any rights or remedies that Purchaser may have against Seller as a result of a breach of any of Seller Representations by Seller or of any covenant of Seller expressly set forth in Section 6.2 or any other
provision of this Agreement or in the Assignment and Assumption Agreement, subject to the terms and limitations on Seller’s liability as set forth in Section 9.4 and elsewhere in this Agreement. 

Purchaser acknowledges and agrees that (1) Purchaser may hereinafter discover facts different from or in addition to those now (or at
the Closing) known to Purchaser, (2) Purchaser’s agreement to release, acquit and discharge Seller and the other Seller Parties as set forth herein, and Seller’s obligations described in the proviso immediately preceding this
sentence, shall remain in full force and effect notwithstanding the existence or discovery of any such additional or different facts, (3) Purchaser knowingly waives any rights, privileges and benefits under any federal, state or local law which
may negatively impact the validity or enforceability of any part of the releases set forth in this Agreement, (4) upon the completion of the Closing, Seller shall be deemed to have satisfied all of Seller’s obligations, covenants and
liabilities in this Agreement and in any documents executed by Seller in connection herewith, other than those obligations of Seller that, by the express terms of this Agreement or the Assignment and Assumption Agreement, survive the Closing (in
which case such survival shall be subject to the limitations set forth in this Agreement or as set forth in the Assignment and Assumption Agreement), and (5) Purchaser irrevocably covenants never to commence or prosecute, or to collude with
others to commence or prosecute, against Seller or any other Seller Party any action or proceeding based upon any claim covered by the foregoing release. 

Purchaser understands the legal significance of the foregoing provisions and acknowledges and agrees that the provisions of
Section 6.1(b) and (c) were a material factor in Seller’s acceptance of the Purchase Price and that Seller is unwilling to sell the Property unless Seller and the other Seller Parties are expressly released as set forth
in Section 6.1(b) and (c). 
  

 - 28 - 








 The releases contained in Section 6.1(b) and (c) and elsewhere in
this Agreement include claims of which Purchaser is presently unaware or which Purchaser does not presently suspect to exist, which, if known by Purchaser, would materially affect Purchaser’s release of Seller. Subject to Seller
Representations, Purchaser specifically waives the provisions of any law of any state, territory or jurisdiction the import of which is as follows: 

A general release does not extend to claims which the creditor does not know or suspect to exist in his favor at the time of executing the
release, which if known by him must have materially affected his settlement with the debtor. 
 Notwithstanding anything to the contrary in this
Agreement, the provisions of Section 6.1(b) and (c) shall constitute Surviving Obligations that survive the Closing; 

(d) Purchaser is a limited partnership duly formed, validly existing and in good standing under the laws of the State of Delaware.

 (e) This Agreement constitutes the valid and legally binding obligation of Purchaser, enforceable against Purchaser in
accordance with its terms subject only to applicable bankruptcy, insolvency and similar laws attaching rights of creditors generally, and subject as to enforceability, to general principles of equity (regardless of whether enforcement is sought in a
proceeding in equity or at law); 
 (f) There are no actions, suits or proceedings pending or, to the knowledge of Purchaser,
threatened, against or affecting Purchaser which, if determined adversely to Purchaser, would adversely affect its ability to perform its obligations hereunder; 

(g) Neither the execution, delivery or performance of this Agreement nor compliance herewith (i) conflicts or will conflict with or
results or will result in a breach of or constitutes or will constitute a default under (1) the organizational documents of Purchaser, (2) any law or any order, writ, injunction or decree of any court or governmental authority, or
(3) any agreement or instrument to which Purchaser is a party or by which it is bound or (ii) results in the creation or imposition of any lien, charge or encumbrance upon its property pursuant to any such agreement or instrument;

 (h) No authorization, consent, approval of any governmental authority (including courts) is required for the execution and
delivery by Purchaser of this Agreement or the performance of its obligations hereunder; 
 (i) (i) Purchaser is not, nor is it
controlled directly or indirectly by, nor is it owned directly or to Purchaser’s knowledge indirectly by, any person, group, entity or nation named on any list issued by the Office of Foreign Assets Control of the United States Department of
the Treasury (“OFAC”) pursuant to Executive Order 13224 or any similar list or by any law, order, rule or regulation or any Executive Order of the President of the United States as a terrorist, “Specially Designated
National and Blocked Person” or other banned or blocked person (any such person, group, entity or nation being hereinafter referred to as a “Prohibited Person”); (ii) Purchaser is not (nor is it controlled, directly or
indirectly, by, nor is it owned directly or to Purchaser’s knowledge indirectly, by, any person, group, entity or nation which is) acting directly or indirectly for or on behalf of any Prohibited Person; and (iii) neither Purchaser nor any
person, group, entity or nation which directly or indirectly controls Purchaser or which directly owns, or to Purchaser’s knowledge indirectly owns Purchaser, has conducted or will conduct business or has engaged or will engage in any
transaction or dealing with any Prohibited Person, including, without limitation, the making or receiving of any contribution of funds, goods or services to or for the benefit of a Prohibited Person. In connection with the foregoing, it is expressly
understood and

the purpose of imposing any liability on or creating any duties running from the Designated Purchaser Representatives to Seller and Seller agrees that the Designated Purchaser Representatives shall not have any liability under this Agreement or in
connection with the transactions contemplated hereby.

Purchaser’s written request no earlier than 15 days prior to the Closing, Seller shall provide Purchaser with a draft of the Representation Update and copies of all appropriate supporting documents no less than 7 days prior to the Closing. If a

in which event the parties shall proceed to Closing and Purchaser shall receive a credit in the amount of the Deductible Amount, or (3) of more than $1,000,000, Seller shall have the right to elect (or not elect) to require Purchaser to proceed
to Closing notwithstanding such financial loss and Purchaser would receive

to proceed to Closing notwithstanding the financial loss, Purchaser can elect to require Seller to proceed to Closing, by giving written notice to Seller within two Business Days after Seller has elected not to proceed to Closing, in which event the
parties shall proceed to Closing and Purchaser shall receive a credit in the amount of the Deductible Amount. In any event of a MAC Disclosure that is not covered by clause (a) above, Seller shall have the right, but not the obligation, to cure
the financial loss and the parties agree that if the financial loss is not a quantifiable or a readily ascertainable amount of money, the parties would agree to negotiate in good faith to ascertain the amount of the financial loss and the parties
would then be obligated to proceed to Closing; provided, however, that if the financial loss is not readily quantifiable and the financial loss cannot be determined by the parties prior to the scheduled Closing Date, either party may adjourn the
Closing for a period of up to 30 days and the parties shall submit the determination of the financial loss to an independent arbitrator experienced in the determination at issue and, failing agreement on such a person within 2 days, shall submit the
matter to JAMS in Boston, MA for an expedited adjudication by one of JAMS’ regular panel of judges selected by JAMS. JAMS shall be instructed to determine the matter within the earlier to occur of (1) 15 days and (2) any shorter
period of time that may be required by the Existing Lender or Ground Lessor (subject to any extensions available to the parties) to close the assumption of the Existing Loan or to obtain the Ground Lease Assignment and Consent, as applicable, and
the expenses of JAMS or any other arbitrator selected by the parties shall be shared equally by the parties. If a matter disclosed in any Representation Update would constitute a breach of Seller’s obligations under this Agreement, Seller shall
have the right, but not the obligation, to elect to cure such breach and, if it elects to cure such breach, the right to adjourn the Closing for up to 10 days to attempt to effectuate such cure. If Purchaser suffers a financial loss and the Closing
occurs, then the Deductible Amount shall, for purposes of Section 9.4, be reduced dollar-for-dollar by the amount so incurred by Purchaser, but in no event shall the Deductible Amount be reduced below $0.

taxes, if any, and all other items of income (other than the Excluded Items) and expense with respect to the Property shall be prorated between Seller and Purchaser as of the Closing Date in accordance with this Section 7.4. Except as
otherwise provided in this Section 7.4, income and expenses shall be prorated on an accrual basis. All apportionments and prorations made hereunder shall be made based on the number of days of ownership of the Property in the period
applicable to the apportionment, with Purchaser entitled to income and responsible for expenses for the Closing Date. Prorations of annual payments will be made based on the number of days of ownership in the applicable annual period. 

(b) Taxes. All real estate taxes assessed against the Real Property shall be prorated between Seller and Purchaser on an accrual
basis based upon the actual current tax bill. If the most recent tax bill received by Seller before the Closing Date is not the actual current tax bill, then Seller and Purchaser shall initially prorate the taxes at the Closing by applying 100% of
the tax rate for the period covered by the most current available tax bill to the latest assessed valuation, and shall reprorate the taxes retroactively when the actual current tax bill is then available; provided, however, that in no
event shall Seller be charged with or responsible for any increase in real estate taxes resulting from the sale of the Property to Purchaser or from any improvements made or Leases entered into on or after the Closing. All

  

 - 37 - 








 
real estate taxes accruing before the Closing Date shall be the obligation of Seller and all such taxes accruing on and after the Closing Date shall be the obligation of Purchaser. Any refunds of
real estate taxes made after the Closing shall first be applied to the unreimbursed third-party costs incurred by Seller or Purchaser in obtaining the refund, and the balance, if any, shall be paid to Seller (for the period prior to the Closing
Date) and to Purchaser (for the period commencing on and after the Closing Date). If any proceeding to determine the assessed value of the Real Property or the real estate taxes payable with respect to the Real Property has been commenced before the
Effective Date and shall be continuing as of the Closing Date, Seller shall be authorized to continue to prosecute such proceeding and shall be entitled to any abatement proceeds therefrom allocable to any period before the Closing Date, and
Purchaser agrees to cooperate as reasonably requested with Seller and to execute any and all documents reasonably requested by Seller in furtherance of the foregoing. 

(c) Assessment Installments. If there are special assessments imposed by any municipal or governmental authority and pending
against the Property, Seller shall pay any installments of such special assessments that are due and payable prior to the Closing and Purchaser shall pay all installments of such special assessments on or after the Closing; provided,
however, that Seller shall not be required to pay any installments of special assessments that relate to projects that have not been completed as of the Effective Date. 

(d) Utilities. Final readings and final billings for utilities will be made if possible as of the Closing Date, in which event no
proration shall be made at the Closing with respect to utility bills; otherwise a proration shall be made based upon the parties’ reasonable good faith estimate and a readjustment made within 60 days after Closing. Seller shall receive a credit
at Closing for any Utility Deposits, plus any interest on the Utility Deposits to which the Seller is or will be entitled, that are held as of the Effective Date for the benefit of the Seller. 

(e) Contracts. Prepaid charges, payments and accrued charges under any Contracts assigned to and assumed by Purchaser shall be
prorated at Closing in a manner reasonably acceptable to Seller and Purchaser. Purchaser shall have the right to elect not to assume any Contracts at Closing, with such election to be made by delivery of written notice to Seller not later than
October 31, 2010; provided, however, that (i) Leases, the Normandy Property Management Agreement and Contracts listed as “Non-Terminable” on Schedule 7.4(e) shall not be covered by this Section and
(ii) if any of the Contracts listed on Schedule 7.4(e) listed as “Terminable With Penalty” are not assumed, Purchaser shall pay all cancellation or termination fees associated therewith. 

(f) Closing Statement. Purchaser and Seller shall cooperate to produce prior to the Closing Date a schedule of prorations and
closing costs that is as complete and accurate as reasonably possible (the “Closing Statement”). If any of the aforesaid prorations cannot be calculated accurately on the Closing Date, then they shall be estimated to the extent
possible as of the Closing and calculated as soon after the Closing Date as is feasible. All adjustments to initial estimated prorations shall be made by the parties with due diligence and cooperation within 60 days following the Closing, or such
later time as may be required to obtain necessary information for proration, by prompt cash payment to the party yielding a net credit from such prorations from the party; provided, however, that the provisions of this paragraph shall
survive the Closing for a period of one (1) year following the Closing, and after such date neither Seller nor Purchaser shall have any further rights or obligations under this Section 7.4 except as otherwise provided in
Section 7.4(g). 
 (g) Closing Costs. Purchaser and Seller shall each be responsible for the costs and
expenses of their own professional advisors (including legal) and for 50% of the Escrow Agent’s fees and expenses for acting as the Escrow Agent. Seller shall pay all Transfer Taxes required in connection with the transfer of the Real Property.

  

 - 38 - 








 (h) Leases. 

(i) All Leases shall be prorated (with prorations of additional rent to be calculated by the earlier to occur of 180 days after Closing
and 90 days after the end of the calendar year). Leases shall not be prorated based on any pending lease audits still ongoing as of the Closing Date other than as expressly set forth in this Agreement. 

(ii) All Tenant LOCs and Cash Security Deposits held by Seller as the landlord under such Lease shall be transferred to Purchaser at
Closing; with Seller agreeing to process the LOC Transfer Documents promptly after Closing and it being agreed and acknowledged it shall be the sole obligation of Purchaser to pay for any transfer fees required to transfer the Tenant LOCs, and there
shall be no proration with respect to such Tenant LOCs or Cash Security Deposits. 
 (iii) Seller shall be obligated to
(A) pay all Bain Lease Obligations in accordance with Section 8.1 hereof as and when due, (B) grant Purchaser a credit at Closing for all tenant improvement allowances/costs for the Leases with Batterymarch Financial Services, Inc.

Wakefield Inc., as tenant broker, and the Leasing Override Commissions payable to Normandy Leasing Agent, in each case attributable to the Initial Premises and the 36th Floor Expansion Space for the initial term of the Bain Lease (but not for any
other expansion options, expansion rights, or renewal terms exercised by Bain Tenant). 
 (iv) (A) Purchaser shall pay all
amounts listed as Buyer Leasing Costs on Schedule 6.2(p) with the leasing commissions to be paid at Closing (whether or not then due) and the tenant improvement costs/allowances to be paid as and when requested by the Tenants,
(B) Purchaser shall grant to Seller a credit for any amounts under clause (A) that Seller pays on Purchaser’s behalf prior to Closing, (C) with respect to the $116,000 account receivable from Weston Presidio owed to landlord for
work performed by landlord at Weston Presidio’s request, if Seller collects such amount prior to Closing, Seller shall be entitled to retain such amount and if it does not, then Seller shall have the right to collect and retain such amount from
Weston Presidio after Closing (and this receivable shall not be subject to the other prorations sections of this Agreement, and Seller can continue to pursue collection efforts promptly after Closing) and Purchaser shall reasonably cooperate with
Seller’s collection efforts, with Seller agreeing that it shall not have the right to terminate such Tenant’s lease, (D) Purchaser shall be obligated to pay, and shall pay, all Tenant Costs under all leases or lease amendments
executed after the Effective Date, (E) Purchaser shall pay all leasing commissions which may become due and payable to the Normandy Leasing Agent for any additional space leased by Bain Tenant after the Effective Date for the 29th

 - 39 - 








 
the Effective Date and a commission is payable with respect thereto in accordance with the terms of the C&W Leasing Agreement. For the avoidance of doubt, except as expressly
set forth in clause (E) above or on Schedule 6.2(p), no leasing commissions shall be payable by the Purchaser to Normandy Leasing Agent regardless of whether or not the same is anticipated to be paid to Normandy Leasing Agent in the
C&W Leasing Agreement. 
 (i) Excluded Items. Purchaser acknowledges and agrees that, notwithstanding anything to the
contrary in this Agreement or the Assignment and Assumption Agreement, (i) the Purchase Price does not include payment for the Excluded Items, the Loan Reserves, the Cash Security Deposit and the Tenant LOCs and (ii) whether the proceeds
of the same are received before or after the Closing (subject to the prorations set forth in this Agreement), all escrows, reserves, cash, cash equivalents, deposits, bank accounts, certificates of deposit, investments, notes, accounts receivable or
other financial instruments existing as of the Closing or relating to a period prior to Closing (other than the Loan Reserves (excluding any Loan Reserves that form part of the Bain Lease Obligation Security or other amounts held in escrow by
Existing Lender to pay for or secure Seller Work or Other Seller Work), which Loan Reserves (other than such excluded amounts for Seller Work or Other Seller Work) shall become the property of Purchaser at Closing in exchange for the Loan Reserve
Credit granted Seller). The provisions of this paragraph shall survive the Closing without limitation.

ARTICLE 8 

Seller Retained Obligations 

Section 8.1. Seller Work and Other Seller Work. (a) Notwithstanding anything to the contrary contained in this
Agreement, Seller shall be responsible to perform and pay for the Other Seller Work, Café Work, Lobby Work and other work described in Section 5.1(e) (subject in all events to the provisions of such Section so that, for example,
Seller shall have no obligation to Complete any of the work described in Section 5.1(e) to the extent that any such work is taken over by Purchaser and Purchaser is given a credit for the cost to complete such work at Closing pursuant to
Section 5.1(e)), the Chiller Work and the Garage Work (collectively, the “Seller Retained Obligations”) irrespective of whether they are to be performed or paid for before or after the Effective Date or the Closing Date
including, without limitation, any cost overruns incidental thereto that are not caused by Purchaser’s failure to comply with its obligations under this Agreement. After Closing, in the event that any party providing labor, materials, equipment
and/or services for the Seller Retained Obligations files a lien against the Property, the Seller shall within 20 days of receipt of notice regarding such lien, cause the lien to be discharged (either by obtaining and recording a lien discharge bond
from a surety and in a form acceptable to the Owner or otherwise) at no cost to the Purchaser. The Seller Retained Obligations shall be performed in compliance with (A) all applicable laws, codes, ordinances, rules, regulations, permits

  

 - 40 - 








 
and approvals of governmental authorities having jurisdiction over such work, (B) the Bain Lease, (C) the Existing Loan Documents (or are otherwise consented to by the Existing Lender),
and (D) all covenants, conditions, restrictions and other encumbrances affecting or relating to the Property (or applicable consents are obtained). 

(b) In connection with the execution of the Bain Lease, Seller (i) delivered to Bain Tenant an irrevocable letter of credit in the
amount of $23,297,275.00 to secure the tenant improvement allowance for floors 37 through 43 of the Bain Lease (the “TI Allowance Letter of Credit”), (ii) delivered to Bain Tenant an irrevocable letter of credit in the amount
of $7,500,000 (the “$7.5 Million LOC”) to secure Seller’s obligation to pay such amount, or the applicable portion thereof, to Bain Tenant in certain circumstances following Seller’s failure to timely complete the Garage
Work pursuant to the Bain Lease, (iii) deposited $8,305,035 with Existing Lender to secure the payment of the costs of the Garage Work under an agreement (the “Garage Work Reserve Agreement”) with Existing Lender, and
(iv) placed $7,524,219 into escrow with a title company for the costs of the Café Work, the Lobby Work, and the Chiller Work under an agreement (the “Non-Garage Work Escrow Agreement”) with such title company. In
addition, in connection with Bain Tenant’s exercise of its Initial Expansion Option (as defined in the Bain Lease) for the 36th floor, Seller has increased or will, prior to the Closing Date, increase the TI Allowance Letter of Credit by the
required amount of $3,137,125.00 in accordance with the Bain Lease. Collectively, the letters of credit and funds under the preceding two sentences are referred to as the “Bain Lease Obligation Security.” At and after the Closing,
the Bain Lease Obligation Security shall remain in place in accordance with the Bain Lease, subject to Section 5.1(e), Seller shall continue to perform and pay for the Bain Lease Obligations, and Seller shall be permitted to use the Bain
Lease Obligation Security to perform and pay the Bain Lease Obligations in accordance with the respective terms of the Bain Lease, the Garage Work Reserve Agreement, and the Non-Garage Work Escrow Agreement, as the case may be. Seller shall retain
the rights to the Bain Lease Obligation Security and any excess funds therein, in each case to the extent not required for the performance or payment of the respective Bain Lease Obligations that constitute Seller Retained Obligations. Without
limiting the generality of the foregoing, upon Substantial Completion of the Garage Work, Seller shall be entitled to receive any unused funds remaining in the Garage Work Reserve Agreement, together with the original $7.5 Million LOC and/or any
proceeds thereof (and/or any subsequent remittances thereof by Bain Tenant under the terms of the Bain Lease), to the extent not required to satisfy the obligation to pay Bain Tenant the Garage Payment as provided in the Bain Lease, and if Purchaser
shall receive the $7.5 Million LOC or any proceeds therefrom (or subsequent remittances thereof by Bain Tenant under the terms of the Bain Lease), Purchaser shall hold the same in trust for Seller and deliver the same to Seller promptly after
receipt. If the Garage Work is not timely completed such that Bain Tenant has the right to draw all or any portion of the $7.5 Million LOC, (1) Seller shall bear the full economic effect of any draw on the $7.5 Million LOC and Seller shall not
be entitled to any reimbursement therefor from Purchaser, provided that Seller alone shall have the right to receive any remaining undrawn proceeds (and any subsequent remittances thereof by Bain Tenant under the terms of Section 3.5(c) of the
Work Letter attached to the Bain Lease for the fractional reduction of the $7,500,000 Garage Payment (as defined in Section 3.6 of the Work Letter) that Bain Tenant is required to refund to the Guarantor identified in the Work Letter) and shall
have the right to contest the validity of any such draw by Bain Tenant and (2) if Bain Tenant elects, as it is entitled to do under the Bain Lease, not to draw upon the $7.5 Million LOC but instead receive a reduction in rent over time as
provided in the Bain Lease, then Seller shall pay to Purchaser the fractional portion of the $7,500,000 Garage Payment that Bain Tenant would have been entitled to retain if Bain Tenant had elected to receive the Garage Payment instead of such rent
reduction, and Purchaser shall bear the full economic effect of any such rent reduction without further reimbursement therefor from Seller. By way of illustration, if substantial completion of the Garage Work was delayed by 30 days beyond the
Capital Program Outside Completion Date and Bain Tenant had initially drawn the entire $7.5 Million LOC as a result of such delay as provided in Section 3.5(c), then Bain Tenant would be entitled to retain 30/365ths of the $7.5 million so drawn
and would be obligated to remit to the aforesaid Guarantor 335/365th of the 
  

 - 41 - 








 
$7.5 million so drawn; provided, however, that if Bain instead had elected to receive the fractional portion of the rent reduction for such 30-day delay as set forth in Section 3.5(c), then
Seller would be entitled to the return of the cancelled $7.5 Million LOC as provided under Section 3.5(c) and Seller would pay to Purchaser the amount (i.e., 30/365th of $7,500,000) that Bain Tenant would have been entitled to retain had Bain
Tenant elected to receive the Garage Payment instead of the fractional rent reduction under such Section 3.5(c). In addition, Seller shall reimburse Purchaser for the reasonable third-party expenses incurred by Purchaser in providing the valet
service to Bain Tenant under the penultimate sentence of Section 28.1 of the Bain Lease, to the extent attributable to Seller’s delay in performing the Garage Work, as more particularly provided therein. 

(c) From and after the Effective Date, Seller shall invite and afford Purchaser and Purchaser’s representatives the opportunity (at
Purchaser’s expense) to participate in the supervision and oversight of the completion of the Bain Lease Obligations, as reasonably required from time to time by Purchaser. Seller shall obtain the reasonable approval of Purchaser with respect
to any Material Change Orders (as defined below) for the Garage Work or Chiller Work; provided, however, that Purchaser agrees that (1) it shall respond to Seller’s request for approval within two Business Days and failure to respond by
the second Business Day shall be deemed an approval, (2) if Seller believes that Purchaser unreasonably denied its approval (other than for any Discretionary Scope Change Order, as defined below), Seller shall have the right to request the
contractor and the architect for such work to determine whether, in their judgment, Purchaser’s denial was in fact reasonable, whereupon such determination shall be binding and final on each of Purchaser and Seller with respect to the
reasonableness of the denial, and if Purchaser’s denial shall be determined to have been unreasonable, then such change order shall be deemed to be approved and Seller shall be entitled to proceed with the work, as modified by such change
order, and (3) with respect to any Discretionary Scope Change Order, Purchaser shall not be deemed to be unreasonable in withholding its approval if such change order would materially reduce the scope or quality of the work (including, without
limitation, the number of parking spaces, quality of construction, or quantity of materials) shown on the plans and specifications listed on Schedule 6.2(dd). In no event shall any such change order deviate from the requirements of the Garage
Work or Chiller Work, as applicable, under the Bain Lease or the Garage Work Reserve Agreement or this Agreement. “Material Change Order” shall mean any change order for the work (including without limitation any change orders for
substitution of materials, changes required to address unexpected field conditions, and any other matters), other than minor changes that are required to be made in the field (or within less than two Business Days in the ordinary course) provided
that such minor changes do not materially reduce the scope or quality of the work (including, without limitation, the number of parking spaces, quality of construction, or quantity of materials) shown on the plans and specifications listed on
Schedule 6.2(dd). “Discretionary Scope Change Order” means any Material Change Order that does not arise from the unavailability of materials, materielmen, or suppliers, the substitution of materials of like quality, unexpected
field conditions, governmental or other third party requirements, or events or conditions beyond Seller’s reasonable control. 

(d) In the event that Purchaser from time to time after the Closing requests that Seller make a change to the Garage Work or the Chiller
Work (which change shall not deviate from the requirements for such work, as applicable, under the Bain Lease or the Garage Work Reserve Agreement or materially change the scope of the work shown on the plans and specifications listed on Schedule
6.2(dd)), Seller shall reasonably cooperate with Purchaser (at no cost to Seller) in evaluating and/or implementing such requested changes, provided that (i) Purchaser pays any and all costs arising from such change or requested change,
(ii) any such change will not cause any delay in the Garage Work or the Chiller Work (unless Purchaser agrees to pay for all additional costs to complete the work on the original schedule), (iii) Purchaser’s requested changes are
permitted under (A) applicable laws, codes, ordinances, rules, regulations, permits and approvals of governmental authorities having jurisdiction over such work, (B) the Bain Lease and any other Lease, (C) the Loan Documents (or are
otherwise consented to by the 
  

 - 42 - 








 
Existing Lender), and (D) all covenants, conditions, restrictions and other encumbrances affecting or relating to the Property (or applicable consents are obtained). Purchaser shall be
solely responsible for all costs, expenses, and liability incurred by Seller in connection with any changes requested by Purchaser, including without limitation any costs, expenses, or liability incurred by Seller under the Bain Lease in the event
of a delay in the Garage Work caused by such changes, whether any such delay is then expected or thereafter arises on account of such change requested by Purchaser. Except in connection with a termination for cause under the applicable contract,
Seller shall not replace the general contractor or architect for the Garage Work or the Chiller Work shown on Schedule 6.2(ee) without Purchaser’s prior approval, which approval shall not be unreasonably withheld, conditioned, or delayed
provided that the replacement general contractor or architect (as the case may be) has experience and qualifications for comparable construction projects and is acceptable to Existing Lender (to the extent Existing Lender’s approval is required
under the Garage Work Reserve Agreement or Loan Documents, as the case may be). 
 (e) Purchaser acknowledges and agrees that
the Garage Work and the Chiller Work is not expected to be Completed prior to Closing and that, following Closing, Normandy Property Manager shall continue to supervise the contractors under the Garage Construction Contract and cause the Garage Work
and Chiller Work to be Completed in accordance with this Agreement, the Loan Documents and the terms of the Bain Lease as part of the Bain Lease Obligations; provided, however, that (i) Purchaser shall not be obligated to pay a
construction management fee pursuant to the Normandy Property Management and Leasing Agreement or otherwise for such supervision and (ii) if requested by Existing Lender in connection with the Lender Consent, Seller and Purchaser shall
collaterally assign to Existing Lender all rights of Seller and Purchaser in and to the Garage Contract and all benefits of the owner thereunder. Seller shall be responsible for obtaining all consents, approvals, and permits from tenants, lenders,
governmental authorities, and other third parties required to perform such work, and (to the extent, if any, the same have not heretofore been obtained and are hereafter required in order to carry out such work) Purchaser shall reasonably cooperate
with Seller in obtaining the same (all without cost to Purchaser), including without limitation the execution of customary permit applications, submissions, and related materials required to be made by the owner of the Property in the ordinary
course of the work. In connection with Seller’s completion of the Seller Retained Obligations, Purchaser shall cooperate with Seller or its representative to permit Seller to perform its obligations to complete the Seller Retained Obligations,
including granting access to the Property and delegating owner’s rights to enforce and act as owner’s representative under the Garage Construction Contract and other relevant agreements to Normandy Property Manager until the Garage Work
and Chiller Work is Substantially Completed. 
 (f) After the Effective Date and (as applicable under this Section 8.1)
after the Closing, Seller shall (i) perform the Seller Retained Obligations in accordance with the plans and specifications on Schedule 6.2(dd) (subject to the provisions of this Section 8.1) and in accordance with the requirements of
Section 3.5 of the Work Letter (to the extent applicable), the Loan Documents, and (as applicable) the Garage Work Reserve Agreement and the Non-Garage Work Escrow Agreement and (ii) provide to Purchaser copies of all requisitions,
submissions, and other notices given or received by Seller under the Section 3.5 of the Work Letter, the Loan Documents, the Garage Work Reserve Agreement, or the Non-Garage Work Escrow Agreement (as the case may be) with respect to such work,
including, without limitation, copies of all requisition packages, lien waivers, architects’ certificates of substantial completion, certificates of occupancy, and all other close-out documentation relating to Completion of such work as
required under the terms thereof. Seller shall assign to Purchaser all rights and warranties (but not any obligations) under the applicable design and construction contracts for the Seller’s Work at the Closing (to the extent the applicable
portions of the Seller’s Work have been Completed prior to the Closing) or after the Closing (promptly after Completion of each portion of the Seller’s Work that is Completed after the Closing). To the extent not covered by such
assignment, Seller shall execute after Completion of such work such instruments as may be reasonably requested by Purchaser to confirm the transfer to Purchaser of all of Seller’s ownership rights and interests in and to all

  

 - 43 - 








 
plans, specifications, warranties, project manuals, and other design documents in connection with such work. After such assignment following Completion of the work, Seller have no liability or
obligation to pursue any warranty claims or other claims for deficient, defective or nonconforming design or construction, provided that, to the extent that any such warranty or claim is not assignable to Purchaser as aforesaid, Seller will
reasonably cooperate with Purchaser at Purchaser’s request (at no cost to Seller) in the enforcement of such warranty or claim against the applicable contractor, to the extent such warranty or claim is required to be made in Seller’s name
pursuant to the applicable contract. With respect to the portions of the Seller Retained Obligations to be performed by Seller after the Closing Date, (1) Seller shall require the respective contractors to update their liability insurance for
such work to name each of Purchaser, Boston Properties Limited Partnership and BPI as an additional insured to the same extent as Seller and shall provide certificates thereof to Purchaser promptly upon receipt, and shall cause Normandy Property
Manager (and, as applicable, Seller, in respect of the activities of Seller at the Property under this Section 8.1) to name each of Purchaser, Boston Properties Limited Partnership and BPI as an additional insured on its commercial general
liability policies, and (2) Seller and Purchaser shall reasonably cooperate to enable each party to receive the benefits of any indemnifications in favor of the “Owner” under the applicable contracts for such work, including by
seeking written instruments from the architect(s) and contractor(s) for all such work naming Purchaser, Boston Properties Limited Partnership and BPI as indemnified parties to the same extent as Seller. After the Effective Date and (as applicable
under this Section 8.1) after Closing, Seller shall give permit Purchaser, at Purchaser’s expense, to attend weekly job meetings and to monitor the progress of the work, and Purchaser shall promptly furnish Seller with a copy of any
notices or other material communications (if any) received from Bain Tenant, Existing Lender, or any other party with respect to such work. Seller shall deliver to Bain Tenant the architect’s certification and estoppel certificate as to
substantial completion of the respective portions of Seller’s Work under Section 3.5(d) of the Work Letter, either before or after the Closing as the case may be, and (if requested by Seller after the Closing) Purchaser will forward such
items (as provided by Seller) to Bain Tenant under Section 3.5(d) of the Work Letter and reasonably cooperate with Seller (at no cost to Purchaser) in obtaining such estoppel certificate from Bain Tenant. 

(g) Purchaser agrees that all Bain Lease Obligation Security shall be retained by Seller and not assigned to Purchaser or, to the extent
it is so assigned as part of the Lender Consent, Purchaser shall agree that Seller shall retain all of the beneficial right and interest in such Bain Lease Obligation Security and Purchaser shall fully cooperate with Seller in obtaining the release
of funds from the Bain Lease Obligation Security, including making requisitions to Existing Lender, so as to provide to Seller the full benefit of such Bain Lease Obligation Security for the completion of the Bain Lease Obligations to which it
applies or, to the extent such Bain Lease Obligation Security is required by Existing Lender to remain as collateral security for the performance of the related Bain Lease Obligations, to transfer such remaining Bain Lease Obligation Security to the
escrow account held by the title company under the Non-Garage Work Escrow Agreement. Purchaser hereby agrees to indemnify, defend and hold Seller harmless from and against any and all Losses arising out of (i) any default by Purchaser under the
Existing Loan after the Closing Date that results in Seller’s inability to timely use the Bain Lease Obligation or (ii) any breach by Purchaser or its agents of Purchaser’s obligations under Article 8, including, without limitation,
the obligation to grant Seller and the Garage Contractor and their respective agents and sub-contractors access to the Property after the Closing Date. In the event that the Defeasance Election is exercised by Purchaser, the parties will enter into
a mutually acceptable escrow arrangement with respect to the Bain Lease Obligation Security that is returned to Seller to the extent not prohibited by the Bain Lease and, if prohibited, shall be delivered into such escrow arrangement as soon as it
is no longer prohibited. 
 (h) For purposes of Section 8.1 and this Agreement, Completion of each component of the Bain
Lease Obligations (i.e., the Lobby Work, the Café Work, the Chiller Work, and the Garage Work, respectively) shall be deemed to have occurred upon delivery to Purchaser of (i) a copy of the

  

 - 44 - 








 
Final Close-Out Package (as defined below) for such component in accordance with the Garage Work Reserve Agreement or the Non-Garage Work Escrow Agreement, as the case may be, and
(ii) either an estoppel certificate executed by Bain Tenant evidencing that such component has been substantially completed under the terms of the Work Letter under Section 3.5(d) of the Work Letter or Seller’s certification that Bain
Tenant has not disputed the occurrence of substantial completion of such component under the terms of Section 3.5(d) of the Work Letter, together with copies of all relevant materials submitted to Bain Tenant in connection with the
Section 3.5(d) submission. As used herein, “Final Close-Out Package” shall mean the final close-out package required to be submitted (in the case of the Garage Work) to the Existing Lender under Section 4 of Exhibit A to the
Garage Work Reserve Agreement and (in the case of the Lobby Work, the Café Work or the Chiller Work, as the case may be) to the Escrow Agent under Section 1(b) of the Non-Garage Work Escrow Agreement with respect to such component of the
work. All Other Seller Work and other work described in Section 5.1(e) shall be deemed Completed upon delivery to Purchaser of copies of final lien waivers, evidence of final payment, and (if applicable) an architect’s or contractor’s
certificate of substantial completion and, if applicable, confirmation of satisfaction of all lease requirements which are a precondition to the Completion of such work. 

(i) The obligations under this Article 8 shall constitute Surviving Obligations. 

Section 8.2. Review and Auditing of Records. Upon written request of Purchaser, from the Effective Date and for a
period of two (2) years following the Effective Date, Seller shall make its records relating to the Property available to Purchaser for inspection, copying and audit by Purchaser’s accountants at Purchaser’s sole cost and expense.
Without limiting the foregoing, from the Effective Date and for a period of two (2) years following the Effective Date, Seller shall, from time to time, upon reasonable advance notice from Purchaser and at Purchaser’s sole cost and
expense, provide Purchaser and its representatives, agents and employees with access to the financial and other information in Seller’s possession that (i) relates to the operation of the Property, (ii) pertains to the period of
Seller’s ownership of the Property, and (iii) is both relevant and reasonably necessary, in the opinion of Purchaser’s independent, third-party, certified public accountants, to enable Purchaser and Purchaser’s outside,
third-party, certified public accountants to prepare financial statements on a timely basis in compliance with any or all of (A) Rule 3-14 and Rule 3-05 of Regulation S-X of the Securities and Exchange Commission, (B) any other rule issued
by the Securities and Exchange Commission and applicable to Purchaser or its affiliates, or (C) any registration statement, report or disclosure statement filed with the Securities Exchange Commission by, or on behalf of, Purchaser or its
affiliates (with the understanding, however, that any such inquiry that is made by Purchaser or Purchaser’s independent, third-party, certified public accountants shall pertain solely to the affairs of Seller as the owner and operator of the
Property, and shall not extend to the financial or other information of any direct or indirect owner of Seller or any of the affairs of any such direct or indirect owner of Seller or that is otherwise of a confidential or proprietary nature). Seller
shall provide for the previous fiscal year and the period through and including the Closing Date such information and documentation, if available and at Purchaser’s sole cost and expense, including but not limited to: 

(i) rent rolls; 

(ii) Seller’s internally-prepared operating statements and prior years’ audited financial statements including supporting work
papers and documentation; 
 (iii) access to the Leases and all information available on tenant improvements and commissions for
prior fiscal years; 
 (iv) Seller’s budgeted annual and monthly income and expenses, and actual annual and monthly income
and expenses; 
  

 - 45 - 








 (v) access to Seller’s cash receipt journal(s) and bank statements for the Property;

 (vi) Seller’s general ledger with respect to the Property; 

(vii) Seller’s schedule of expense reimbursements required under the Leases in effect on the Closing Date, if one exists;

 (viii) loan amortization schedules and interest statements; 

(ix) a schedule, if one exists, of those items of repairs and maintenance performed by, or at the direction of Seller; 

(x) a schedule, if one exists, of those capital improvements and fixed asset additions made by, or at the direction of, the Seller;

 (xi) access to Seller’s invoices with respect to expenditures; and 

(xii) access (during normal and customary business hours) to responsible personnel designated by Seller to answer accounting questions.

 ARTICLE 9 

Termination and Default 

Section 9.1. Termination without Default. If the sale of the Property is not consummated because of the failure to
obtain the Required Consents by the Outside Consent Date that is not due to a default by Purchaser in its obligation to purchase the Property in accordance with the provisions of this Agreement, then this Agreement shall terminate, the Deposit shall
be returned to Purchaser and the parties shall have no further liability to each other except for the Effective Date Surviving Obligations. 

Section 9.2. Purchaser’s Default. If the sale of the Property contemplated hereby is not consummated because of a
default by Purchaser in its obligation to purchase the Property in accordance with the terms of this Agreement, or if Purchaser shall default in the performance of any of its other material obligations to be performed on or before the Closing Date,
and such Purchaser default is not the result of a Seller’s default as described in Section 9.3, then: (a) this Agreement shall terminate; (b) the Deposit shall be paid to and retained by Seller as liquidated damages; and
(c) except for the Effective Date Surviving Obligations, Seller and Purchaser shall have no further obligations to each other. THE PARTIES HERETO, BEFORE ENTERING INTO THIS AGREEMENT, ACKNOWLEDGE THAT SUBSTANTIAL DAMAGES WILL BE SUFFERED BY
SELLER IN THE EVENT THAT PURCHASER SHOULD FAIL TO PURCHASE THE PROPERTY SUBJECT TO AND IN ACCORDANCE WITH THE TERMS AND CONDITIONS OF THIS AGREEMENT. PURCHASER AND SELLER ACKNOWLEDGE THAT THE DAMAGES TO SELLER IN THE EVENT OF A BREACH OF THIS
AGREEMENT BY PURCHASER WOULD BE DIFFICULT OR IMPOSSIBLE TO DETERMINE, THAT THE AMOUNT OF THE DEPOSIT REPRESENTS THE PARTIES’ BEST AND MOST ACCURATE ESTIMATE OF THE DAMAGES THAT WOULD BE SUFFERED BY SELLER IF THE TRANSACTION SHOULD FAIL TO CLOSE
DUE TO PURCHASER’S DEFAULT AND THAT SUCH ESTIMATE IS REASONABLE UNDER THE CIRCUMSTANCES EXISTING AS OF THE EFFECTIVE DATE AND UNDER THE CIRCUMSTANCES THAT SELLER AND PURCHASER REASONABLY ANTICIPATE WOULD EXIST AT THE TIME OF SUCH BREACH. THE
PARTIES, HAVING MADE A DILIGENT ENDEAVOR TO ASCERTAIN THE ACTUAL COMPENSATORY DAMAGES WHICH SELLER WOULD SUFFER IN THE EVENT OF 

 

 - 46 - 








 
PURCHASER’S FAILURE TO PURCHASE THE PROPERTY SUBJECT TO AND IN ACCORDANCE WITH THE TERMS AND CONDITIONS OF THIS AGREEMENT, HEREBY AGREE THAT THE REASONABLE ESTIMATE OF SAID DAMAGES IS THE
SUM EQUAL TO THE AMOUNT OF THE DEPOSIT. THEREFORE, IN THE EVENT THAT THE SALE CONTEMPLATED HEREBY SHALL FAIL TO CLOSE FOR ANY REASON OTHER THAN SELLER’S DEFAULT HEREUNDER OR THE FAILURE OF ANY CONDITION PRECEDENT IN FAVOR OF PURCHASER EXPRESSLY
SET FORTH IN THIS AGREEMENT, SELLER SHALL BE ENTITLED TO AND SHALL RETAIN THE ENTIRE DEPOSIT AS LIQUIDATED DAMAGES AND AS ITS SOLE REMEDY AT LAW OR IN EQUITY. THE AMOUNT OF THE LIQUIDATED DAMAGES HAS BEEN ESTABLISHED BY THE PARTIES AS THE AMOUNT OF
THE MONETARY DAMAGES SELLER WILL SUFFER BASED SOLELY UPON A FAILURE BY PURCHASER TO PURCHASE THE PROPERTY AND SELLER SHALL BE ENTITLED TO RECOVER NO OTHER DAMAGES FROM PURCHASER BASED SOLELY UPON A FAILURE BY PURCHASER TO PURCHASE THE PROPERTY.

 This Section 9.2 is intended only to liquidate and limit Seller’s right to damages arising due to Purchaser’s
failure to purchase the Property in accordance with the terms of this Agreement and shall not limit the Effective Date Surviving Obligations of Purchaser under this Agreement. In no event shall Purchaser ever have any liability under this Agreement
for indirect, consequential or punitive damages. 
 Section 9.3. Seller’s Default. If the sale
contemplated hereby is not consummated because of a default by Seller in its obligation to sell the Property in accordance with the terms of this Agreement, or if Seller shall default in the performance of any of its other material obligations to be
performed on or before the Closing Date (it being acknowledged that with respect to any default arising from a breach of any Seller Representations, Seller shall have the right, but not the obligation, to elect to cure such breach and, if it elects
to cure such breach, the right to adjourn the Closing for up to 10 days to attempt to effectuate such cure), then Purchaser may, as its sole and exclusive remedy by reason thereof (in lieu of prosecuting an action for damages or proceeding with any
other legal course of conduct, the right to bring such actions or proceedings being expressly and voluntarily waived by Purchaser, to the extent legally permissible, following and upon advice of counsel): (a) terminate this Agreement by giving
written notice thereof to Seller, in which event, if such default has actually occurred, the Deposit will be returned to Purchaser, and thereafter the parties shall have no further obligation to each other except for the Effective Date Surviving
Obligations, or (b) initiate and prosecute an action for specific performance by Seller of its obligations under this Agreement within thirty (30) days after the occurrence of such default and, in connection with such action, recover from
Seller its actual out-of-pocket attorneys fees and expenses. Purchaser agrees that its failure timely to commence such an action for specific performance within such thirty (30) day period shall be deemed a waiver by it of its right to commence
such an action. 
 Section 9.4. Breach of Representations; Survival Periods. 

(a) Subject to Section 9.4(b), any Seller Representations shall survive the Closing until the date that is 180 days from the
date of Closing (“Survival Period”) and no action or proceeding thereon shall be valid or enforceable, at law or in equity, unless Purchaser shall have duly commenced a legal proceeding against Seller within the Survival Period
alleging that Seller was in breach of such representation or warranty when made, and that Purchaser has suffered actual damages as a result thereof; however, if such proceeding is so duly commenced with respect to a breach thereof prior to the
expiration of the Survival Period, Seller’s liability (and the credit support provided by the Fund Guaranty) with respect to such breach only shall continue until a final, unappealable resolution of any such claim and any final judgment or
settlement in favor of Purchaser is satisfied in full. 
  

 - 47 - 








 (b) Notwithstanding anything to the contrary contained in this Agreement or in any document
executed in connection herewith, but subject to the Survival Period set forth in Section 9.4(a), and to the provisions of Section 9.4(c) and (d) below, (i) the maximum aggregate liability of Seller arising
with respect to a breach by Seller of any or all of Seller’s Representations and for any other matters arising out of or relating to this Agreement or the transactions contemplated hereby, shall not exceed Fifteen Million Dollars ($15,000,000)
(the “Maximum Liability Amount”) and (ii) Seller shall have no liability whatsoever arising with respect to a breach by Seller of any or all of Seller’s Representations unless and until the aggregate liability for all or
any such breaches equals or exceeds Five Hundred Thousand Dollars ($500,000) (the “Deductible Amount”) (and if such liability exceeds $500,000, then Seller shall have liability for all such breaches, subject to the Maximum Liability
Amount, but without regard to the $500,000 deductible); provided, however, that the Maximum Liability Amount shall not apply to (A) loss, cost or damages incurred by Purchaser as a result of a default by Seller hereunder which is determined by
a court of competent jurisdiction to have been the result of fraud, willful misconduct or bad faith on the part of Seller or (B) liability under the indemnification of Seller pursuant to Section 10.23. 

(c) Notwithstanding anything contained in this Agreement to the contrary, in no event shall Seller ever have any liability under this
Agreement for indirect, consequential or punitive damages. 
 (d) If the Closing occurs, Purchaser hereby expressly waives,
relinquishes and releases any right or remedy available to it at law, in equity, under this Agreement or otherwise to make a claim against Seller for damages that Purchaser may incur, or to rescind this Agreement and the transactions contemplated
hereby, as the result of any of Seller Representations being untrue, inaccurate or incorrect if Purchaser had actual knowledge that such Seller Representation or warranty was untrue, inaccurate or incorrect at the time of the Closing. 

ARTICLE 10

assignee is a wholly-owned direct or indirect subsidiary of Purchaser and complies with the requirements of Section 5.7 and the other obligations of Purchaser under this Agreement. For any assignment, the original named Purchaser shall remain
jointly and severally liable under this Agreement with any assignee. Any attempted assignment in violation hereof shall, at the election of Seller, be declared null and void and of no force or effect and shall constitute a default by Purchaser.

  

 - 48 - 








 Section 10.4. Waiver. The excuse or waiver of the performance by a party
of any obligation of the other party under this Agreement shall only be effective if evidenced by a written statement signed by the party so excusing or waiving. No delay in exercising any right or remedy shall constitute a waiver thereof, and no
waiver by Seller or Purchaser of the breach of any covenant of this Agreement shall be construed as a waiver of any preceding or succeeding breach of the same or any other covenant or condition of this Agreement. 

Section 10.5. Governing Law.

instituted by any party hereto on or with respect to this Agreement or which in any way relates, directly or indirectly, to this Agreement or any event, transaction, or occurrence arising out of or in any way connected with this Agreement or the
Property, or the dealings of the parties with respect thereto, shall be tried only by a court sitting in the Borough of Manhattan and the parties hereto hereby submit to the exclusive jurisdiction of any federal or state court sitting in such
Borough. EACH PARTY HEREBY EXPRESSLY WAIVES ANY RIGHT TO A TRIAL BY JURY IN ANY SUCH SUIT, ACTION, OR PROCEEDING.

 Any address or name specified above may be changed by notice given to the addressee by the
other party in accordance with this Section 10.7. The inability to deliver notice because of a changed address of which no notice was given as provided above, or because of rejection or other refusal to accept any notice, shall be deemed
to be the receipt of the notice as of the date of such inability to deliver or rejection or refusal to accept. Any notice to be given by any party hereto may be given by the counsel for such party. 

Section 10.8. Attorneys’ Fees. In the event of a judicial or administrative proceeding or action by one party
against the other party with respect to the interpretation or enforcement of this Agreement, the prevailing party shall be entitled to recover reasonable costs and expenses including reasonable attorneys’ fees and expenses, whether at the
investigative, pretrial, trial or appellate level. The prevailing party shall be determined by the court based upon an assessment of which party’s major arguments or position prevailed. 

Section 10.9. IRS Real Estate Sales Reporting. Purchaser and Seller hereby agree that the Escrow Agent shall act as
“the person responsible for closing” the transaction which is the subject of this Agreement pursuant to Section 6045(e) of the Code and shall prepare and file all informational returns, including IRS Form 1099-S, and shall otherwise
comply with the provisions of Section 6045(e) of the Code. 
 Section 10.10. Time Periods. Any reference
in this Agreement to the time for the performance of obligations or elapsed time shall mean consecutive calendar days, months, or years, as applicable. In the event the time for performance of any obligation hereunder expires on a day that is not a
Business Day, the time for performance shall be extended to the next Business Day. 
 Section 10.11. Modification of
Agreement. No modification of this Agreement shall be deemed effective unless in writing and signed by both Seller and Purchaser. 

Section 10.12. Further Instruments. Each party, promptly upon the request of the other, shall execute and have
acknowledged and delivered to the other or to Escrow Agent, as may be appropriate, any and all further instruments reasonably requested or appropriate to evidence or give effect to the provisions of this Agreement and which are consistent with the
provisions of this Agreement. 
 Section 10.13. Descriptive Headings; Word Meaning. The descriptive headings
of the paragraphs of this Agreement are inserted for convenience only and shall not control or affect the meaning or construction of any provisions of this Agreement. Words such as “herein”, “hereinafter”, “hereof” and
“hereunder” when used in reference to this Agreement, refer to this Agreement as a whole and not merely to a subdivision in which such words appear, unless the context otherwise requires. The singular shall include the plural and the
masculine gender shall include the feminine and neuter, and vice versa, unless the context otherwise requires. The word “including” shall not be restrictive and shall be interpreted as if followed by the words “without
limitation.” 
 Section 10.14. Time of the Essence. Time is of the essence of this Agreement and all
covenants and deadlines hereunder; provided that the Closing Date may be adjourned for up to one (1) Business Day by either party. Without limiting the foregoing, Purchaser and Seller hereby confirm their intention and agreement that time shall
be of the essence of each and every provision of this Agreement, notwithstanding any subsequent modification or extension of any date or time period that is provided for under this Agreement. The agreement of Purchaser and Seller that time is of the
essence of each and every provision of this Agreement shall not be waived or modified by any conduct of the parties, and the agreement of Purchaser and Seller that time is of the essence of each and every provision of this

  

 - 51 - 








 
Agreement may only be modified or waived by the express written agreement of Purchaser and Seller that time shall not be of the essence with respect to a particular date or time period, or any
modification or extension thereof, which is provided under this Agreement. 
 Section 10.15. Construction of
Agreement. This Agreement shall not be construed more strictly against one party than against the other merely by virtue of the fact that it may have been prepared primarily by counsel for one of the parties, it being recognized that both
Purchaser and Seller has contributed substantially and materially to the preparation of this Agreement. 

Section 10.16. Severability. The parties hereto intend and believe that each provision in this Agreement comports with
all applicable local, state and federal laws and judicial decisions. If, however, any provision in this Agreement is found by a court of law to be in violation of any applicable local, state, or federal law, statute, ordinance, administrative or
judicial decision, or public policy, or if in any other respect such a court declares any such provision to be illegal, invalid, unlawful, void or unenforceable as written, then it is the intent of all parties hereto that, consistent with and with a
view towards preserving the economic and legal arrangements among the parties hereto as expressed in this Agreement, such provision shall be given force and effect to the fullest possible extent, and that the remainder of this Agreement shall be
construed as if such illegal, invalid, unlawful, void, or unenforceable provision were not contained herein, and that the rights, obligations, and interests of the parties under the remainder of this Agreement shall continue in full force and
effect. 
 Section 10.17. No Recording. The provisions hereof shall not constitute a lien on the Property.
Neither Purchaser nor its agents or representatives shall record or file this Agreement or any notice or memorandum hereof in any public records. If Purchaser breaches the foregoing provision, this Agreement shall, at Seller’s election,
terminate, and Seller shall retain the Deposit in accordance with Section 9.2. Purchaser hereby irrevocably appoints Seller as its true and lawful attorneys-in-fact, coupled with an interest, for the purpose of executing and recording
such documents and performing such other acts as may be necessary to terminate any recording or filing of this Agreement in violation of this provision. Nothing contained herein shall be deemed to limit Seller’s remedies under Section 9.2
hereof. 
 Section 10.18. No Implied Agreement. Neither Seller nor Purchaser shall have any obligations in
connection with the transaction contemplated by this Agreement unless both Seller and Purchaser, each acting in its sole discretion, elects to execute and deliver this Agreement to the other party. No correspondence, course of dealing or submission
of drafts or final versions of this Agreement between Seller and Purchaser shall be deemed to create any binding obligations in connection with the transaction contemplated hereby, and no contract or obligation on the part of Seller or Purchaser
shall arise unless and until this Agreement is fully executed by Seller and Purchaser. Once executed and delivered by Seller and Purchaser, this Agreement shall be binding upon them notwithstanding the failure of Escrow Agent or any broker or other
Person to execute this Agreement. 
 Section 10.19. Facsimile/PDF Signature. Signatures to this Agreement,
any amendment hereof and any notice given hereunder, transmitted electronically or by facsimile shall be valid and effective to bind the party so signing. Each party agrees to promptly deliver an execution original of this Agreement (and any
amendment hereto) with its actual signature to the other party, but a failure to do so shall not affect the enforceability of this Agreement (or any amendment hereto), it being expressly agreed that each party to this Agreement shall be bound by its
own electronically transmitted or facsimiled signature and shall accept the electronically transmitted or facsimiled signature of the other party to this Agreement. 

 

 - 52 - 








 Section 10.20. Brokers. (a)Seller represents and warrants to Purchaser
that it has dealt with no broker, salesman, finder or consultant with respect to this Agreement or the Contemplated Transactions other than Cushman & Wakefield Inc, whose commission and all other compensation due to it for the Contemplated
Transactions (the “Commission”) shall be paid by Seller pursuant to a separate agreement. Seller agrees to indemnify, protect, defend and hold Purchaser harmless from and against all claims, losses, damages, liabilities, costs,
expenses (including reasonable attorneys’ fees and disbursements at the investigative, trial and appellate levels) and charges resulting from Seller’s breach of the foregoing representation and covenant in this
Section 10.20(a). The provisions of this Section 10.20(a) shall constitute Effective Date Surviving Obligations. 

(b) Purchaser represents and warrants to Seller that it has dealt with no broker, salesman, finder or consultant with respect to this
Agreement or the Contemplated Transactions other than Cushman & Wakefield Inc. Purchaser agrees to indemnify, protect, defend and hold Seller harmless from and against all claims, losses, damages, liabilities, costs, expenses (including
reasonable attorneys’ fees and disbursements) and charges resulting from Purchaser’s breach of the foregoing representations in this Section 10.20(b). The provisions of this Section 10.20(b) shall constitute
Effective Date Surviving Obligations. 
 (c) From and after the Effective Date, Seller shall request and endeavor to obtain from
C&W a letter agreement or an estoppel certificate, in form mutually and reasonably agreed to between Seller and Purchaser, stating that all leasing commissions pursuant to the Bain Lease have been paid by Seller and acknowledging that C&W is
protected under its brokerage agreement for any lease by covering the Protected Tenants listed on Schedule 6.2(gg) attached hereto. 

Section 10.21. Exculpation. It is understood and agreed that, notwithstanding the fact that BPI is the general partner
of Purchaser or that Normandy Fund and Five Mile Fund are the indirect owners of Seller, in no event shall BPI, Normandy Fund or Five Mile Fund, or their respective members, partners, shareholders, officers, directors or employees have any liability
to any party arising out of this Agreement, the transactions contemplated herein, or any document delivered in connection with the transaction contemplated hereby; provided, however, that the foregoing shall not have any effect on the
Fund Guaranty. The provisions of this Section 10.21 shall survive the Closing or a termination of this Agreement. 

Section 10.22. Like-Kind Exchange. Purchaser shall have the right to structure the acquisition of the Property as a
forward or reverse exchange thereof for other real property of a like-kind to be designated by Purchaser (including the ability to assign this Agreement to an entity established in order to effectuate such exchange), with the result that the
exchange shall qualify for non-recognition of gain or loss under Section 1031 of the Internal Revenue Code of 1986, as amended, in which case Seller shall execute any and all documents reasonably necessary to effect such exchange, and otherwise
assist and cooperate with Purchaser in effecting such exchange, provided that: (i) any costs and expenses incurred by Seller as a result of structuring such transaction as an exchange, as opposed to an outright sale, shall be borne by
Purchaser; (ii) Purchaser shall indemnify and hold harmless Seller from and against any and all liabilities, costs, damages, claims or demands arising from the cooperation of Seller in effecting the exchange contemplated hereby; (iii) such
exchange shall not result in any delay in closing the transaction without Seller’s prior written consent; and (iv) such exchange shall not result in any material delay or undue complication in obtaining the Required Consents. 

Section 10.23. Seller Indemnity Obligations; Seller Credit Support. Seller hereby agrees to indemnify, defend and hold
Purchaser harmless from and against any and all claims, liabilities, losses, damages, judgments, costs and expenses, including, but not limited to, reasonable attorneys’ fees and 

 

 - 53 - 








 
disbursements but excluding, in all cases, indirect, consequential or punitive damages (collectively, “Losses”) arising out of: 

(a) the failure by Seller to perform its obligations with respect to the Seller Retained Obligations (other than Other Seller Work for
which the provisions of this Section 10.23 shall not apply) under and in accordance with the provisions of Section 8 or under the Bain Lease, including, without limitation, any cost overruns from the Completion of the Bain
Lease Obligations and the exercise of any remedies available to Bain Tenant under the Bain Lease as a result thereof (in which event Purchaser shall, following Closing, grant Seller access to the 100 Clarendon garage facility and otherwise
reasonably cooperate with Seller if required to mitigate the Loss caused by any such failure and to honor the remedies available to Bain Tenant under the Bain Lease to address such failure) (but in no event shall Seller have any liability for Losses
(i) attributable to a matter for which Purchaser is obligated to indemnify Seller pursuant to Section 8.1(g), (ii) covered by insurance maintained by the Garage Contractor (or other contractor for such work), Seller, or
Purchaser or (iii) attributable to claims from Tenants or subtenants or other third parties for nuisance, breach of quiet enjoyment or similar consequential claims not caused by the negligence, willful misconduct, breach of an express
obligation under such Tenant’s Lease or a breach of Section 8.1 by Seller or any Person it Controls) and the failure by Seller to pay (or cause to be funded from the TI Allowance Letter of Credit) amounts required to be paid as and
when required and in accordance with Section 7.4(h)(iii)(E); and provided that as between Seller and any insurance maintained by the Garage Contractor or Seller, Seller intends that such insurance shall be primary of any liability of
Seller; 
 (b) subject to the provisions of Section 9.4, the failure by Seller to pay any actual damages for which
Seller is adjudicated liable as a result of Seller’s breach of its representations and warranties under Section 6.2; 

(c) (i) any claim by Bain Tenant that the Bain PPA, in and of itself, imposes upon Purchaser, as landlord under the Bain Lease, any
obligation or (ii) any claim by Bain Tenant, as tenant under the Bain Lease, that the Bain PPA creates in favor of Bain Tenant any setoff or other right under the Bain Lease, but only to the extent that Seller has not, on or prior to the
Closing Date or at any time thereafter, provided Purchaser with a duly authorized and executed letter agreement delivered by Bain Tenant to Purchaser whereby Bain Tenant acknowledges and agrees as follows: the Bain PPA does not impose upon
Purchaser, as landlord under the Bain Lease, any obligation and does not afford to Bain Tenant, as tenant under the Bain Lease, any setoff or other right under the Bain Lease, or words to similar effect (collectively, the “Bain
Acknowledgment”), it being agreed that upon the delivery of a Bain Acknowledgment, Seller shall have no further liability to Purchaser under this Section 10.23(d). 

The obligations of Seller under Section 10.23(a), (b), and (c) (collectively, the “Guaranteed
Obligations”) shall be severally (in accordance with the percentage interest in BPH of the members of BPH that each guarantor indirectly controls) guaranteed by each of the Normandy Fund and the Five Mile Fund pursuant to the Fund Guaranty
for all claims asserted for such Guaranteed Obligations prior to (A) with respect to Section 10.23(a), (1) the Completion of the Lobby Work in the case of the Lobby Work, (2) the Completion of the Café Work in the case of
the Café Work, (3) in the case of the Chiller Work, 90 days after the Completion of the Chiller Work, provided Purchaser and its agents shall have such 90 day period to independently confirm that the Chiller Work has been Completed (and,
if no objection has been delivered to Seller within such 90 day period, such confirmation shall be deemed to have been given and Seller’s indemnification obligations under this Agreement with respect to the Chiller Work shall be deemed to be
discharged), (4) in the case of the Garage Work, 90 days after the Completion of the Garage Work provided that Purchaser and its agents shall have such 90 day period to independently confirm that the Garage Work has been Completed (and, if no
objection has been delivered to Seller within such 90 day period and Seller’s indemnification obligations under this Agreement with respect to the Garage 

 

 - 54 - 








 
Work shall be deemed to be discharged) and (5) upon Completion of Landlord’s Initial Work in the case of Landlord’s Initial Work, (B) the end of the Survival Period in the
case of Section 10.23(b), and (C) one year after the Closing Date in the case of Section 10.23(c). The provisions of this Section 10.23 shall constitute Surviving Obligations.
