the apportionments referred to herein is referred to as the “Closing Balance” and, after the application of such apportionments is referred to as the “Adjusted Closing Balance”).” 

 3. Section 3.01 of the Original Contract is hereby deleted, in its entirety, and replaced with the

expressly therein TIME OF THE ESSENCE by the Seller. 
  
 4. Clause
“(vi)” of Section 3.03(a) of the Original Contract is hereby deleted in its entirety. 
  
 5. Section 3.07 of the Original Contract is hereby deleted in its entirety and replaced with the following: “Realty Transfer Fee; Prepayment Fee

attorneys’ fees. All fees, costs and expenses not specifically allocated in this Agreement shall be paid in accordance with the usual custom and practice in northern New Jersey.” 
  
 6. In Section 3.09 of the Contract, all references to “Closing
Date” shall be deemed replaced with references to “June 15, 2004.”

strict accordance with the confidentiality standards set forth in this Section 4.7 . In permitting Purchaser to review the Property Documents or any other information, Seller has not waived any privilege or claim of confidentiality with
respect thereto, and no third party benefits or relationships of any kind, either express or implied, have been offered, intended or created. 
  
 Section 4.8 No Representation or Warranty by Seller. Purchaser acknowledges that, except as expressly set forth in this Agreement, Seller
has not made and does not make any warranty or representation regarding the truth, accuracy or completeness of the Property Documents or the source(s) thereof. Purchaser further acknowledges that some if not all of the Property Documents were
prepared by third parties other than Seller. Seller expressly disclaims any and all liability for representations or warranties (other than representations and warranties of Seller expressly set forth in this Agreement and any other instrument
executed by Seller in connection with this Agreement), express or implied, statements of fact and other matters contained in such information, or for omissions from the Property Documents, or in any other written or oral communications transmitted
or made available to Purchaser. Purchaser acknowledges that, except for the representations and warranties of Seller expressly set forth in this Agreement and any other instrument executed be Seller in connection with this Agreement, Purchaser shall
rely solely upon its own investigation with respect to the Property, including, without limitation, the Property’s physical, environmental or economic condition, compliance or lack of compliance with any ordinance, order, permit or regulation
or any other attribute or matter relating thereto. Seller has not undertaken any independent investigation as to the truth, accuracy or completeness of the Property Documents and are providing the Property Documents solely as an accommodation to

 Section 4.10 Purchaser’s Agreement to Indemnify. Purchaser hereby agrees to indemnify, defend and hold Seller harmless from and against
any and all liens, claims, causes of action, damages, liabilities and expenses (including reasonable attorneys’ fees) arising out of Purchaser’s inspections or tests permitted under this Agreement or any violation of the provisions of
Section 4.3, Section 4.7, and Section 4.9, including any and all claims or causes of action which a Tenant may bring against Seller arising out of Purchaser’s breach of its obligation under Section 4.7 above to
maintain the confidential nature of any Property Documents or other information relative to such Tenant; provided, however, the indemnity shall not extend to protect Seller from any pre-existing liabilities for matters merely discovered by Purchaser
(i.e., latent environmental contamination) so long as Purchaser’s actions do not aggravate any pre-existing liability of Seller. Purchaser’s obligations under this Section 4.10 shall survive the termination of this Agreement and
shall survive the Closing. 
  
 Section 4.11 Environmental
Studies; Seller’s Right to Terminate. As additional consideration for the transaction contemplated in this Agreement, Purchaser must provide to Seller, immediately following the receipt of same by Purchaser, copies of any and all
reports, tests or studies involving contamination of or other environmental concerns relating to the Property; provided, however, Purchaser shall have no obligation to cause any such tests or studies to be performed on the Property. Seller
acknowledges that Purchaser has not made and does not make any warranty or representation regarding the truth or accuracy of any such studies or reports. Notwithstanding Section 4.10 above, Purchaser shall have no liability or culpability of
any nature as a result of having provided such information to Seller or as a result of Seller’s reliance thereon or arising out of the fact that Purchaser merely conducted such tests or studies, so long as Purchaser’s actions do not
aggravate any pre-existing liability of Seller. In the event that such reports, tests or studies indicate the existence or reasonable potential existence of any contamination of any portion of the Property that is not disclosed in the Property
Documents and that is material (meaning that the reasonably estimated cost of remediation and/or other liability associated therewith, as determined by Seller’s environmental consultants, exceeds $150,000.00), then Seller may terminate this
Agreement by giving written notice to Purchaser within ten (10) business days after Purchaser has provided Seller with copies of such reports, tests or studies, whereupon the Earnest Money shall be returned to Purchaser, Purchaser shall be entitled
to recover from Seller all costs and expenses, not to exceed $75,000.00 in the aggregate, incurred by Purchaser in connection with its investigation of the Property and review of the Property Information, and the parties shall have no further
obligations hereunder except for obligations that expressly survive the termination hereof. 

 Article 5 
 TITLE AND SURVEY 
  
 Section 5.1 Title Commitment. Seller has delivered to Purchaser on or before the Effective Date: (a) a current commitment for title insurance (the “Title Commitment”) issued by the Title Company, in the
amount of the Purchase Price and on an ALTA 1992 Standard Form commitment, with Purchaser as the proposed insured, and (b) copies of all documents of record referred to in the Title Commitment as exceptions to title to the Property. 
  
 Section 5.2 New or Updated Survey. Purchaser may elect to
obtain a new survey or revise, modify, or re-certify an existing survey (“Survey”) as necessary in order for the Title Company to delete the survey exception from the Title Policy or to otherwise satisfy Purchaser’s
objectives. 
  
 Section 5.3 Title Review. During the
Inspection Period, Purchaser shall have the right to review title and survey matters with respect to the Property. Seller shall have no obligation to cure title objections except liens of an ascertainable amount (but expressly excluding any lien
that is caused to be created by, under or through a Tenant) created by, under or through Seller, which liens Seller shall cause to be released at or prior to Closing, including, without limitation, the lien related to that certain Deed of Trust,
Assignment of Rents and Leases and Security Agreement filed of record as of the Effective Date (with Seller having the right to apply the Purchase Price or a portion thereof for such purpose), and Seller shall deliver the Property free and clear of
any such liens. Seller further agrees to remove any exceptions or encumbrances to title which are voluntarily created by, under or through Seller after the Effective Date without Purchaser’s consent (if requested, such consent shall not be
unreasonably withheld or delayed). The term “Permitted Exceptions” shall mean: the specific exceptions (excluding exceptions that are part of the promulgated title insurance form) in the Title Commitment that the Title
Company has not agreed to remove from the Title Commitment as of the end of the Inspection Period and that Seller is not required to remove as provided above; matters created by, through or under Purchaser; items shown on the Survey which have not
been removed as of the end of the Inspection Period (or if Purchaser does not obtain a Survey, all matters that a current, accurate survey of the Property would show); real estate taxes not yet due and payable; rights of Tenants under the Leases;
rights of tenants or licensees under License Agreements; and any licensees under any Service Contracts not terminated as of Closing. 
  
 Section 5.4 Delivery of Title Policy at Closing. In the event that the Title Company does not issue at Closing, or unconditionally commit at
Closing to issue, to Purchaser, an owner’s title policy in accordance with the Title Commitment, insuring Purchaser’s title to the Property in the amount of the Purchase Price, subject only to the standard exceptions and exclusions from
coverage contained in such policy and the Permitted Exceptions (the “Title Policy”), Purchaser shall have the right to terminate this Agreement, in which case the Earnest Money shall be immediately returned to Purchaser and
the parties hereto shall have no further rights or obligations, other than those that by their terms survive the termination of this Agreement. 

 Article 6 
 OPERATIONS AND RISK OF LOSS 
  
 Section 6.1 Ongoing Operations. From the first day of the Inspection Period through Closing: 
  
 6.1.1 Leases, Service Contracts and License Agreements. Seller will perform its material obligations under the Leases, Service Contracts and
License Agreements. 
  
 6.1.2 New Contracts. Except
as provided in Section 6.1.4, Seller will not enter into any contract that will be an obligation affecting the Property subsequent to the Closing, except contracts entered into in the ordinary course of business that are terminable without
cause and without the payment of any termination penalty on not more than 30 days’ prior notice. 
  
 6.1.3 Maintenance of Improvements; Removal of Personal Property. Subject to Section 6.2 and Section 6.3 and the provisions of
this Section 6.1.3, Seller shall maintain or cause the Tenants under the Leases to maintain all Improvements substantially in their present condition (ordinary wear and tear and casualty excepted) and in a manner consistent with Seller’s
maintenance of the Improvements during Seller’s period of ownership. Seller will not remove any Tangible Personal Property except as may be required for necessary repair or replacement, and replacement shall be of approximately equal quality
and quantity as the removed item of Tangible Personal Property. If a condition arises after the Risk Transfer Date which Seller determines requires repair or replacement in order to maintain the Property in the manner required by this Section
6.1.3, Seller shall give written notice to Purchaser of such condition. Seller shall not be obligated to make such repair or replacement unless Purchaser requests in writing that the repair or replacement be made, in which event Seller shall
receive a credit at Closing for the amount that such repair or replacement exceeds $2,500; provided, however, that Seller will not receive a credit if the condition giving rise to the repair or replacement occurred prior to the Risk Transfer Date,
and Seller will not receive a credit to the extent Seller is able pursuant to the Leases to pass the cost of the repair or replacement through to the Tenants. Notwithstanding Purchaser’s assumption of certain risks on the Risk Transfer Date,
Seller agrees to maintain until the Closing Date Seller’s current insurance policy for risk of loss to the Property. 
  
 6.1.4 Leasing; License Agreements. Seller will not amend or terminate any existing Lease or License Agreement or enter into any new Lease or
new License Agreement without Purchaser’s approval, in Purchaser’s sole and absolute discretion. If Purchaser does not respond to Seller’s written request for approval within two (2) business days after receipt thereof by Purchaser,
then Purchaser will be deemed to have approved such amendment, termination or new Lease or License Agreement. Purchaser shall have no approval rights, however, with respect to any item under existing Leases which, by the express terms of such Lease,
Landlord is either required to approve or to which Landlord has no approval rights. 
  
 Section 6.2 Damage. Seller assumes all risk of loss to the Property prior to the Risk Transfer Date. Purchaser assumes all risk of loss to the Property on or after the Risk Transfer Date. 

 6.2.1 Damage Prior to Risk Transfer Date. If the Property is damaged by fire or other
casualty prior to the Risk Transfer Date, Seller shall estimate the cost to repair and the time required to complete repairs and will provide Purchaser written notice of Seller’s estimation (the “Casualty Notice”) as
soon as reasonably possible after the occurrence of the casualty. 
  
 (a) Material. In the event of any Material Damage to or destruction of the Property or any portion thereof on or prior to the Risk Transfer Date, Purchaser may, at its sole option, terminate this
Agreement by delivering written notice Seller on or before the thirtieth (30th) day after the date Seller delivers
the Casualty Notice to Purchaser (and if necessary, the Closing Date shall be extended to give Purchaser the full 30-day period to make such election and to allow Seller time to obtain insurance settlement agreements with Seller’s insurers).
Upon any such termination, the Earnest Money shall be returned to Purchaser and the parties hereto shall have no further rights or obligations hereunder, other than those that by their terms survive the termination of this Agreement. If Purchaser
does not so terminate this Agreement within said 30-day period, then the parties shall proceed under this Agreement and close on schedule (subject to extension of Closing as provided above), and as of Closing Seller shall assign to Purchaser,
without representation or warranty by or recourse against Seller, all of Seller’s rights in and to any resulting insurance proceeds (including, without limitation, all rent loss insurance applicable to any period on and after the Closing Date)
due Seller as a result of such damage or destruction, Purchaser shall accept the Property in its then-existing condition, and Purchaser shall receive a credit at Closing for any deductible amount under such insurance policies (but the amount of the
deductible plus insurance proceeds shall not exceed the lesser of (a) the cost of repair or (b) the Purchase Price and a pro rata share of the rental or business loss proceeds, if any). If Seller is not able to assign the insurance proceeds to
Purchaser at Closing for any reason, the parties shall proceed with Closing as otherwise set forth in this Section 6.2.1, with Purchaser receiving a credit at Closing in the amount of the insurance proceeds that Seller is unable to assign to
Purchaser. For the purposes of this Agreement, “Material Damage” and “Materially Damaged” means damage which, in Seller’s reasonable estimation, exceeds $250,000.00 to repair. 
  
 (b) Not Material. If the Property is not
Materially Damaged, then neither Purchaser nor Seller shall have the right to terminate this Agreement, and if such damage occurs on or prior to the Risk Transfer Date, Seller shall, at its option, either (a) repair the damage before the Closing in
a manner reasonably satisfactory to Purchaser (and if necessary, Seller may extend the Closing Date up to 30 days to complete such repairs), or (b) credit Purchaser at Closing for the reasonable cost to complete the repair (in which case Seller
shall retain all insurance proceeds and Purchaser accept the Property in its then-existing condition). 
  
 6.2.2 Damage On or After Risk Transfer Date. If the Property is damaged by fire or other casualty on or after the Risk Transfer Date, Seller
shall assign to Purchaser, without representation or warranty by or recourse against Seller, all of Seller’s rights in and to any resulting insurance proceeds (including, without limitation, all rent loss insurance applicable to any period on
and after the Closing Date) due Seller as a result of such damage or destruction, Purchaser shall accept the Property in its then-existing condition, and Purchaser shall receive a 

 credit at Closing for any deductible amount under such insurance policies (but the amount of the deductible plus
insurance proceeds shall not exceed the lesser of (a) the cost of repair or (b) the Purchase Price and a pro rata share of the rental or business loss proceeds, if any). If Seller is not able to assign the insurance proceeds to Purchaser at Closing
for any reason, the parties shall proceed with Closing as otherwise set forth in this Section 6.2.2, with Purchaser receiving a credit at Closing in the amount of the insurance proceeds that Seller is unable to assign to Purchaser.

  
 Section 6.3 Condemnation. If proceedings in
eminent domain are instituted with respect to the Property or any portion thereof prior to the Risk Transfer Date, Purchaser may, at its option, by written notice to Seller given within ten (10) days after Seller notifies Purchaser in writing of
such proceedings (and if necessary the Closing Date shall be extended to give Purchaser the full ten-day period to make such election), either: (a) terminate this Agreement, in which case the Earnest Money shall be immediately returned to Purchaser
and the parties hereto shall have no further rights or obligations, other than those that by their terms survive the termination of this Agreement, or (b) proceed under this Agreement, in which event Seller shall, at the Closing, assign to Purchaser

 Section 7.2 Conditions to Parties’ Obligation to Close. In
addition to all other conditions set forth herein, the obligation of Seller, on the one hand, and Purchaser, on the other hand, to consummate the transactions contemplated hereunder are conditioned upon the following:

operation or value of the Property or the other party’s ability to perform its obligations under this Agreement. 

 So long as a party is not in default hereunder, if any condition to such party’s obligation to
proceed with the Closing hereunder has not been satisfied as of the Closing Date (or such earlier date as is provided herein), subject to any applicable notice and cure periods provided in Section 10.1 and Section 10.2, such party may,
in its sole discretion, terminate this Agreement by delivering written notice to the other party on or before the Closing Date (or such earlier date as is provided herein), or elect to close (or to permit any such earlier termination deadline to
pass) notwithstanding the non-satisfaction of such condition, in which event such party shall be deemed to have waived any such condition. In the event such party elects to close (or to permit any such earlier termination deadline to pass),
notwithstanding the non-satisfaction of such condition, said party shall be deemed to have waived said condition, and there shall be no liability on the part of any other party hereto for breaches of representations and warranties of which the party
electing to close had knowledge at the Closing. 
  
 Section 7.3
Seller’s Deliveries in Escrow. As of or prior to the Closing Date, Seller shall deliver in escrow to Escrow Agent the following:

“Assignment”), executed and acknowledged by Seller; 
  
 7.3.3 Conveyancing or Transfer Tax Forms or Returns. Such conveyancing or transfer tax forms or returns, if any, as are required to be delivered or signed by Seller by applicable state and local law in
connection with the conveyance of the Real Property; 
  
 7.3.4

behalf of Seller reasonably satisfactory to the underwriter for the Title Policy; 
  
 7.3.6 Additional Documents. Any additional documents that Escrow Agent or the Title Company may reasonably require for the proper consummation of the transaction contemplated by this Agreement (provided,
however, no such additional document shall expand any obligation, covenant, representation or warranty of Seller or result in any new or additional obligation, covenant, representation or warranty of Seller under this Agreement beyond those
expressly set forth in this Agreement); and 
  
 7.3.7 Tenant
Estoppel Certificates. Tenant Estoppel Certificates substantially in the form of Exhibit G (or, if a tenant’s Lease specifies or contemplates another form of tenant estoppel certificate, then such other specified or contemplated

John J. McMullen Associates (the “Major Tenants”) and (b) tenants (including the Major Tenants) occupying not less than eighty percent (80%) of the rentable square feet in the Improvements leased to tenants including the
Major Tenants. Seller shall use commercially reasonable efforts to obtain, but shall not be obligated to expend any funds (other than copying, postage and related charges) in connection with obtaining any such tenant estoppel certificates, and the
failure of Seller to obtain any such tenant estoppel certificates shall not be a breach or default hereunder. If, despite using commercially reasonable efforts, Seller is unable to obtain the tenant estoppel certificates referred to in this
Section 7.3.7, then Purchaser’s sole remedies and recourses shall be limited to either (a) waiving the requirement for the tenant estoppel certificate(s) in question and proceeding to Closing without reduction of the Purchase Price or
(b) terminating this Agreement by written notification to Seller at Closing, in which event this Agreement shall be terminated as provided for in Section 10.2. If Purchaser extends the Closing Date pursuant to either Section 7.1.1,
Section 7.1.2 or Section 7.1.3, the tenant estoppel certificates obtained by Seller may be dated more than 30 days prior to the Closing Date. In such event, Seller will use reasonable efforts to obtain updated tenant estoppel
certificates from the Tenants upon the request of Purchaser, but the failure to receive an updated tenant estoppel certificate from any or all Tenants shall not in any way be deemed a failure of this condition to close and will not give Purchaser a
right to terminate this Agreement so long as Seller has previously delivered to Purchaser the estoppels required under this Section 7.3.7. 
  
 7.3.8 Seller’s Certificate of Representations and Warranties. A certificate in the form of Exhibit J attached hereto, dated as

tenants under Leases and/or tenants or licensees under License Agreements after Closing shall be applied in the following order of priority: (A) first, to payment of the current Tenant Receivables then due for the month in which the Closing Date

remit to the other any such sums so received to which the other is entitled within ten (10) business days after receipt thereof less reasonable, actual costs and expenses of collection, including reasonable attorneys’ fees, court costs and
disbursements, if any. With respect to Unbilled Tenant Receivables, Purchaser covenants and agrees to (A) bill the same when billable and (B) cooperate reasonably with Seller to determine the correct amount of operating expenses and/or taxes due.
The provisions of this Section 8.1.3(a) shall survive the Closing. 
  
 (b) Without limiting the generality of the requirements of Section 8.1.3(a)(B), if the final reconciliation or determination of operating expenses and/or taxes due under the Leases shows that a net amount is
owed by Seller to Purchaser, said amount shall be paid by Seller to Purchaser within ten business days of such final determination under the Leases. If the final determination of operating expenses and/or taxes due under the Leases shows that a net
amount is owed by Purchaser to Seller, Purchaser shall, within ten business days of such final determination, remit said amount to Seller. Purchaser agrees to receive and hold any monies received on account of such past due expenses and/or taxes in

of Credit. All tenant and licensee security deposits collected (and interest thereon if required by law or contract) shall be transferred or credited to Purchaser at Closing. As of the Closing, Purchaser shall assume Seller’s
obligations related to tenant and licensee security deposits, but only to the extent they are credited or transferred to Purchaser. Seller shall assign the Irrevocable Standby Letter of Credit No. SM417695C in the amount of $367,269.75 issued on

Purchaser is currently in compliance with and shall at all times prior to the Closing remain in compliance with the regulations of OFAC (including those named on OFAC’s Specially Designated and Blocked Persons List) and any statute, executive
order (including the September 24, 2001, Executive Order Blocking Property and Prohibiting Transactions with Persons Who Commit, Threaten to Commit, or Support Terrorism), or other governmental action relating thereto. Neither Purchaser nor any of
Purchaser’s general partners nor any of Purchaser’s limited partners having a twenty percent (20%) ownership interest or greater in Purchaser, and none of Purchaser’s directors is, nor will they become at any time prior to the
Closing, a person or entity with whom U.S. persons or entities are restricted from doing business under regulations of OFAC (including those named on OFAC’s Specially Designated and Blocked Persons List) or under any statute, executive order

 (including the September 24, 2001, Executive Order Blocking Property and Prohibiting Transactions with Persons Who
Commit, Threaten to Commit, or Support Terrorism), or other governmental action and is not and will not engage at any time prior to the Closing in any dealings or transactions or be otherwise associated with such persons or entities. 
  
 Section 9.3 Survival of Representations and Warranties. The
representations and warranties set forth in this Article 9 and in the certificates to be delivered by Seller at Closing pursuant to Section 7.3.8 shall not be deemed to be merged into or waived by the instruments of Closing, but shall
survive the Closing for a period of nine months (the “Survival Period”). Terms such as “to Seller’s knowledge,” “to the best of Seller’s knowledge” or like phrases
mean the actual present and conscious awareness or knowledge of Anna O. Graves, who is the person most knowledgeable of Seller and the Property (“Seller’s Representative”), without any duty of inquiry or investigation;
provided that so qualifying Seller’s knowledge shall in no event give rise to any personal liability on the part of Seller’s Representative, or any of them, or any other officer or employee of Seller, on account of any breach of any
representation or warranty made by Seller herein. Said terms do not include constructive knowledge, imputed knowledge, or knowledge Seller or such persons do not have but could have obtained through further investigation or inquiry. No broker,
agent, or party other than Seller is authorized to make any representation or warranty for or on behalf of Seller. Each party shall have the right to bring an action against the other on the breach of a representation or warranty hereunder, but only
on the following conditions: (a) the party bringing the action for breach first learns of the breach after Closing and files such action within the Survival Period, and (b) neither party shall have the right to bring a cause of action for a breach
of a representation or warranty unless the damage to such party on account of such breach (individually or when combined with damages from other breaches) equals or exceeds $100,000.00. Neither party shall have any liability after Closing for the
breach of a representation or warranty hereunder of which the other party hereto had knowledge as of Closing. Notwithstanding any other provision of this Agreement, any agreement contemplated by this Agreement, or any rights which Purchaser might
otherwise have at law, equity, or by statute, whether based on contract or some other claim, Purchaser agrees that any liability of Seller to Purchaser on account of a breach of a representation or warranty set forth in Section 9.1 will be limited
to $1,000,000.00 (the “Cap”) (it being understood, however, that the Cap shall not apply to any liability that Seller may have to Purchaser, whether for breach of a representation or warranty or otherwise, as a result
of any of the following [the “Uncapped Breaches”]: (i) Seller’s fraud; (ii) brokerage fees or commissions as a result of Seller’s breach of its obligations in Section 8.6 in connection with this
transaction; or (iii) a breach of the representations in Section 9.1.1, Section 9.1.2, or Section 9.1.15). The provisions of this Section 9.3 shall survive the Closing. Any breach of a representation or warranty that
occurs prior to Closing shall be governed by Article 10. 
  
 Article 10 
 DEFAULT AND REMEDIES 
  
 Section 10.1 Seller’s Remedies. If Purchaser fails to consummate the purchase of the Property pursuant to
this Agreement or fails to comply with its obligations hereunder in all material respects at or prior to Closing for any reason except failure by Seller to perform hereunder, or if prior to Closing any one or more of Purchaser’s representations
or warranties are breached in any material respect, and such default or breach is not cured by the earlier of the 

 tenth (10th) business day after written notice thereof from Seller or the Closing Date (except no notice or cure period
shall apply if Purchaser fails to consummate the purchase of the Property hereunder), Seller shall be entitled, as its sole remedy (except as provided in Section 4.10, Section 8.6, Section 10.3 and Section 10.4 hereof),
to terminate this Agreement and recover the Earnest Money as liquidated damages and not as penalty, in full satisfaction of claims against Purchaser hereunder. Seller and Purchaser agree that Seller’s damages resulting from Purchaser’s
default are difficult, if not impossible, to determine and the Earnest Money is a fair estimate of those damages which has been agreed to in an effort to cause the amount of such damages to be certain. Notwithstanding anything in this Section
10.1 or in Exhibit I to the contrary, in the event of Purchaser’s default or a termination of this Agreement, Seller shall have all remedies available at law or in equity in the event Purchaser or any party related to or affiliated
with Purchaser is asserting any claims or right to the Property that would otherwise delay or prevent Seller from having clear, indefeasible and marketable title to the Property, and in said event Seller shall not be required to submit such matter
to arbitration as contemplated by Exhibit I. In all other events Seller’s remedies shall be limited to those described in this Section 10.1 and Section 4.10, Section 8.6, Section 10.3 and Section 10.4
hereof. If Closing is consummated, Seller shall have all remedies available at law or in equity in the event Purchaser fails to perform any obligation of Purchaser under this Agreement. 
  
 Section 10.2 Purchaser’s Remedies. If Seller fails to consummate the sale of the Property pursuant to
this Agreement or fails to comply with its obligations hereunder in all material respects at or prior to Closing for any reason except failure by Purchaser to perform hereunder, or if prior to Closing any one or more of Seller’s representations
or warranties set forth in Section 9.1.1, Section 9.1.10, Section 9.1.11, Section 9.1.14 or Section 9.1.15 are breached in any material respect, and such default or breach is not cured by the earlier of the tenth
(10th) business day after written notice thereof from Purchaser or the Closing Date (Purchaser hereby agreeing to give such written notice to Seller within one business day after Purchaser first learns of any such default or breach by Seller, except
no notice or cure period shall apply if Seller fails to consummate the sale of the Property hereunder), Purchaser shall elect, as its sole remedy, either to (a) terminate this Agreement by giving Seller timely written notice of such election prior
to or at Closing and recover the Earnest Money plus all costs and expenses, not to exceed $75,000.00 in the aggregate, incurred by Purchaser in connection with its investigation of the Property and review of the Property Information, (b) enforce
specific performance to consummate the sale of the Property and Seller’s obligations hereunder, or (c) waive said failure or breach and proceed to Closing without any reduction in the Purchase Price. Notwithstanding anything herein to the
contrary, Purchaser shall be deemed to have elected to terminate this Agreement if Purchaser fails to deliver to Seller written notice of its intent to file a claim or assert a cause of action for specific performance against Seller on or before
fifteen (15) business days following the scheduled Closing Date or, having given such notice, fails to file a lawsuit asserting such claim or cause of action in Washington D.C. within ninety (90) days following the scheduled Closing Date.
Purchaser’s remedies shall be limited to those described in this Section 10.2 and Section 10.3 and Section 10.4 hereof. IN NO EVENT SHALL SELLER’S DIRECT OR INDIRECT PARTNERS, SHAREHOLDERS, OWNERS OR AFFILIATES, ANY
OFFICER, DIRECTOR, EMPLOYEE OR AGENT OF THE FOREGOING, OR ANY AFFILIATE OR CONTROLLING PERSON THEREOF HAVE ANY LIABILITY FOR ANY CLAIM, CAUSE OF ACTION OR OTHER LIABILITY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE PROPERTY, WHETHER

 BASED ON CONTRACT, COMMON LAW, STATUTE, EQUITY OR OTHERWISE. Notwithstanding anything set forth herein to the contrary,
Purchaser hereby agrees that a breach of a representation or warranty set forth in Section 9.1.2, Section 9.1.3, Section 9.1.4, Section 9.1.5, Section 9.1.6, Section 9.1.7, Section 9.1.8, Section
9.1.9, Section 9.1.12, Section 9.1.13, and Section 9.1.16 which occurs after the Risk Transfer Date shall not be deemed a default by Seller hereunder and Purchaser will not have the right to exercise any remedies otherwise
available to Purchaser pursuant to this Section 10.2, unless such breach is caused by an affirmative act of Seller or the failure of Seller to act where Seller has the obligation to do so. 
  
 Section 10.3 Attorneys’ Fees. In the event either party
hereto employs an attorney in connection with claims by one party against the other arising from the operation of this Agreement, the non-prevailing party shall pay the prevailing party all reasonable fees and expenses, including attorneys’
fees, incurred in connection with such claims. 
  
 Section 10.4
Other Expenses. If this Agreement is terminated due to the default of a party, then the defaulting party shall pay any fees or charges due to Escrow Agent for holding the Earnest Money as well as any escrow cancellation fees or charges
and any fees or charges due to the Title Company for preparation and/or cancellation of the Title Commitment. 
  
 Article 11  
 DISCLAIMERS, RELEASE AND INDEMNITY 

 
 Section 11.1 Disclaimers By Seller. Except as expressly set
forth in this Agreement, it is understood and agreed that Seller and Seller’s agents or employees have not at any time made and are not now making, and they specifically disclaim, any warranties, representations or guaranties of any kind or
character, express or implied, with respect to the Property, including, but not limited to, warranties, representations or guaranties as to (a) matters of title (other than Seller’s special warranty of title to be contained in the Deed), (b)
environmental matters relating to the Property or any portion thereof, including, without limitation, the presence of Hazardous Materials in, on, under or in the vicinity of the Property, (c) geological conditions, including, without limitation,

Property or any portion thereof is affected by any stream (surface or underground), body of water, wetlands, flood prone area, flood plain, floodway or special flood hazard, (e) drainage, (f) soil conditions, including the existence of instability,
past soil repairs, soil additions or conditions of soil fill, or susceptibility to landslides, or the sufficiency of any undershoring, (g) the presence of endangered species or any environmentally sensitive or protected areas, (h) zoning or building
entitlements to which the Property or any portion thereof may be subject, (i) the availability of any utilities to the Property or any portion thereof including, without limitation, water, sewage, gas and electric, (j) usages of adjoining property,
(k) access to the Property or any portion thereof, (l) the value, compliance with the plans and specifications, size, location, age, use, design, quality, description, suitability, structural integrity, operation, title to, or physical or financial
condition of the Property or any portion thereof, or any income, expenses, charges, liens, encumbrances, rights or claims on or affecting or pertaining to the Property or any part thereof, (m) the condition or use of the Property or compliance of
the Property with any or all past, present or future federal, state or local ordinances, rules, regulations or laws, building, fire or zoning ordinances, codes or other 

 similar laws, (n) the existence or non-existence of underground storage tanks, surface impoundments, or landfills, (o)
any other matter affecting the stability and integrity of the Property, (p) the potential for further development of the Property, (q) the merchantability of the Property or fitness of the Property for any particular purpose, (r) the truth, accuracy
or completeness of the Property Documents, (s) tax consequences, or (t) any other matter or thing with respect to the Property. 
  
 Section 11.2 Sale “As Is, Where Is”. Purchaser acknowledges and agrees that upon Closing, Seller shall sell and convey to
Purchaser and Purchaser shall accept the Property “AS IS, WHERE IS, WITH ALL FAULTS,” except to the extent expressly provided otherwise in this Agreement, including the representations and warranties of Seller set forth in Section
9.1. Except as expressly set forth in this Agreement, Purchaser has not relied and will not rely on, and Seller has not made and is not liable for or bound by, any express or implied warranties, guarantees, statements, representations or
information pertaining to the Property or relating thereto (including specifically, without limitation, Property information packages distributed with respect to the Property) made or furnished by Seller, or any property manager, real estate broker,
agent or third party representing or purporting to represent Seller, to whomever made or given, directly or indirectly, orally or in writing. Purchaser represents that it is a knowledgeable, experienced and sophisticated purchaser of real estate and
that, except as expressly set forth in this Agreement, it is relying solely on its own expertise and that of Purchaser’s consultants in purchasing the Property and shall make an independent verification of the accuracy of any documents and
information provided by Seller. Purchaser will conduct such inspections and investigations of the Property as Purchaser deems necessary, including, but not limited to, the physical and environmental conditions thereof, and shall rely upon same.
Purchaser acknowledges that Seller has afforded Purchaser a full opportunity to conduct such investigations of the Property as Purchaser deemed necessary to satisfy itself as to the condition of the Property and the existence or non-existence or
curative action to be taken with respect to any Hazardous Materials on or discharged from the Property, and will rely solely upon same and not upon any information provided by or on behalf of Seller or its agents or employees with respect thereto,
other than such representations, warranties and covenants of Seller as are expressly set forth in this Agreement. Upon the Risk Transfer Date, Purchaser shall assume the risk that adverse matters, including, but not limited to, adverse physical or
construction defects or adverse environmental, health or safety conditions, may not have been revealed by Purchaser’s inspections and investigations. Purchaser hereby represents and warrants to Seller that: (a) Purchaser is represented by legal
counsel in connection with the transaction contemplated by this Agreement; and (b) Purchaser is purchasing the Property for business, commercial, investment or other similar purpose and not for use as Purchaser’s residence. Purchaser waives any
and all rights or remedies it may have or be entitled to, deriving from disparity in size or from any significant disparate bargaining position in relation to Seller. 
  
 Section 11.3 Seller Released from Liability. Purchaser acknowledges that it will have the opportunity to
inspect the Property during the Inspection Period, and during such period, observe its physical characteristics and existing conditions and the opportunity to conduct such investigation and study on and of the Property and adjacent areas as
Purchaser deems necessary, and, as between Purchaser and Seller only (and not with respect to any other non-affiliated third-party entity), Purchaser hereby FOREVER RELEASES AND DISCHARGES Seller from all responsibility and liability that Seller may
have to Purchaser, Purchaser’s affiliates and/or any 

 entity by, through, or under Purchaser (as opposed to Seller’s responsibility or liability to any other
non-affiliated third-party entity), including without limitation, liabilities under the Comprehensive Environmental Response, Compensation and Liability Act Of 1980 (42 U.S.C. Sections 9601 et seq.), as amended (“CERCLA”),
regarding the condition, valuation, salability or utility of the Property, or its suitability for any purpose whatsoever (including, but not limited to, with respect to the presence in the soil, air, structures and surface and subsurface waters, of
Hazardous Materials or other materials or substances that have been or may in the future be determined to be toxic, hazardous, undesirable or subject to regulation and that may need to be specially treated, handled and/or removed from the Property
under current or future federal, state and local laws, regulations or guidelines, and any structural and geologic conditions, subsurface soil and water conditions and solid and hazardous waste and Hazardous Materials on, under, adjacent to or
otherwise affecting the Property). Purchaser further hereby WAIVES (and by Closing this transaction will be deemed to have WAIVED), as between Purchaser and Seller only (and not with respect to any other non-affiliated third-party entity), any and
all objections and complaints (including, but not limited to, federal, state and local statutory and common law based actions, and any private right of action under any federal, state or local laws, regulations or guidelines to which the Property is
or may be subject, including, but not limited to, CERCLA) that Purchaser may have against Seller and/or Seller’s affiliates concerning the physical characteristics and any existing conditions of the Property. Purchaser further hereby assumes,
as between Purchaser and Seller, the risk of changes in applicable laws and regulations relating to past, present and future environmental conditions on the Property and the risk that adverse physical characteristics and conditions, including,
without limitation, the presence of Hazardous Materials or other contaminants, may not have been revealed by its investigation. Nothing contained in this Section 11.3 shall be deemed an assumption by Purchaser of any liability Seller may have
to any entity other than Purchaser and/or Purchaser’s affiliates as a result of the condition of the Property prior to Closing; rather, this Section 11.3 is intended to be a release and waiver of any claims Purchaser may have against
Seller with respect to the matters described in this Section 11.3. Notwithstanding anything in this Agreement to the contrary, the foregoing waiver and release is not intended to and does not include (but such matters are subject to the
limitations and requirements hereof, including, without limitation, Section 9.3) (i) any claims arising from a breach of Seller’s representations or warranties set forth in this Agreement, or (ii) any obligation or other covenant of
Seller under this Agreement which by its terms survives the Closing. 
  
 Section 11.4 “Hazardous Materials” Defined. For purposes hereof, “Hazardous Materials” means “Hazardous Material,” “Hazardous Substance,” “Pollutant or
Contaminant,” and “Petroleum” and “Natural Gas Liquids,” as those terms are defined or used in Section 101 of CERCLA, and any other substances regulated because of their effect or potential effect on public health and the
environment, including, without limitation, PCBs, lead paint, asbestos, urea formaldehyde, radioactive materials, putrescible materials, and infectious materials. 
  
 Section 11.5 Indemnity. It is the intent of the parties that the Purchaser assume all risk of loss related to
the ownership of the Property from and after the Risk Transfer Date unless such loss was caused by the affirmative act of Seller or by the failure of Seller to act where Seller had an obligation to do so. In that regard, Purchaser agrees to
indemnify, defend and hold Seller harmless of and from any and all liabilities, claims, demands, and expenses of any kind or nature (including, without limitation, in connection with Hazardous Materials) which arise or accrue 

 after the Risk Transfer Date and which are in any way related to the ownership, maintenance, or operation of the Property
but are not caused by an affirmative act of Seller or the failure of Seller to act where Seller is obligated to do so. 
  
 Section 11.6 Survival. The terms and conditions of this Article 11 shall expressly survive the Closing and shall not merge with the
provisions of any closing documents, including, without limitation, the Deed. 
  
 Purchaser acknowledges and agrees that the disclaimers and other agreements set forth herein are an integral part of this Agreement and that Seller would not have agreed to sell the Property to Purchaser for the
Purchase Price without the disclaimers and other agreements set forth above. 
  
 Article 12  
 MISCELLANEOUS 
  
 Section 12.1 Parties Bound; Assignment. This Agreement, and the
terms, covenants, and conditions herein contained, shall inure to the benefit of and be binding upon the heirs, personal representatives, successors, and assigns of each of the parties hereto. Purchaser may assign its rights under this Agreement to
an entity controlling, controlled by, or under common control with Purchaser, including, without limitation, Wells REIT II-80 M Street LLC, a Delaware limited liability company, subject to Section 12.17. The assignee of Purchaser shall assume
all obligations of Purchaser hereunder, but Purchaser shall remain primarily liable for the performance of Purchaser’s obligations. A copy of the fully executed written assignment and assumption agreement shall be delivered to Seller at least
three (3) days prior to Closing.

 Section 12.3 Invalidity and Waiver. If any portion of this
Agreement is held invalid or inoperative, then so far as is reasonable and possible the remainder of this Agreement shall be deemed valid and operative, and, to the greatest extent legally possible, effect shall be given to the intent manifested by
the portion held invalid or inoperative. The failure by either party to enforce against the other any term or provision of this Agreement shall not be deemed to be a waiver of such party’s right to enforce against the other party the same or
any other such term or provision in the future. 
  
 Section 12.4
Governing Law. This Agreement shall, in all respects, be governed, construed, applied, and enforced in accordance with the law of the District of Columbia. 
  
 Section 12.5 Survival. The provisions of this Agreement that contemplate performance after the Closing and the
obligations of the parties not fully performed at the Closing (other than any unfulfilled closing conditions which have been waived or deemed waived by the other party) shall survive the Closing and shall not be deemed to be merged into or waived by
the instruments of Closing. 

 Section 12.6 Entirety and Amendments. This Agreement embodies the entire agreement between
the parties and supersedes all prior agreements and understandings relating to the Property. This Agreement may be amended or supplemented only by an instrument in writing executed by the party against whom enforcement is sought. All Exhibits

 Section 12.8 Confidentiality. Purchaser shall make no public announcement or disclosure of any information related to this Agreement to
outside brokers or third parties, before or after the Closing, without the prior written specific consent of Seller; provided, however, that Purchaser may, subject to the provisions of Section 4.7, (i) make disclosure of this Agreement to its
Permitted Outside Parties as necessary to perform its obligations hereunder, (ii) make disclosure of the transaction contemplated by this Agreement after the Closing as may be required under laws or regulations applicable to Purchaser, including any
filings or disclosures Purchaser is required to make to the United States Securities and Exchange Commission or the United States Internal Revenue Service, and (iii) make disclosure of the Closing of the transaction contemplated by this Agreement
after the Closing to Purchaser’s investors or through a public announcement so long as such disclosure does not mention or make reference to Seller or any of Seller’s affiliated parties. 
  
 Section 12.9 No Electronic Transactions. The parties hereby
acknowledge and agree this Agreement shall not be executed, entered into, altered, amended or modified by electronic means. Without limiting the generality of the foregoing, the parties hereby agree the transactions contemplated by this Agreement
shall not be conducted by electronic means, except as specifically set forth in the “Notices” section of this Agreement.

Notice given by electronic mail in accordance herewith shall be effective upon the entrance of such electronic mail into the information processing system designated by the recipient’s electronic mail address. Except for facsimile and
electronic mail notices as described above, no notice hereunder shall be effective if sent or delivered by electronic means. In no event shall this Agreement be altered, amended or modified by electronic mail or electronic record. A party’s
address may be changed by written notice to the other party; provided, however, that no notice of a change of address shall be effective until actual receipt of such notice. Copies of notices are for informational purposes only, and a failure to
give or receive copies of any notice shall not be deemed a failure to give notice. Notices given by counsel to the Purchaser shall be deemed given by Purchaser and notices given by counsel to the Seller shall be deemed given by Seller. 

 Section 12.11 Construction. The parties acknowledge that the parties and their counsel have
reviewed and revised this Agreement and agree that the normal rule of construction - to the effect that any ambiguities are to be resolved against the drafting party - shall not be employed in the interpretation of this Agreement or any exhibits or
amendments hereto. 
  
 Section 12.12 Calculation of Time
Periods. Unless otherwise specified, in computing any period of time described herein, the day of the act or event after which the designated period of time begins to run is not to be included and the last day of the period so computed is to
be included, unless such last day is a Saturday, Sunday or legal holiday for national banks in the location where the Property is located, in which event the period shall run until the end of the next day which is neither a Saturday, Sunday, or
legal holiday. The last day of any period of time described herein shall be deemed to end at 5:00 p.m. local time in the state in which the Real Property is located. 
  
 Section 12.13 Execution in Counterparts. This Agreement may be executed in any number of counterparts, each of
which shall be deemed to be an original, and all of such counterparts shall constitute one Agreement. To facilitate execution of this Agreement, the parties may execute and exchange by telephone facsimile counterparts of the signature pages,
provided that executed originals thereof are forwarded to the other party on the same day by any of the delivery methods set forth in Section 12.9 other than facsimile. 
  
 Section 12.14 No Recordation. Without the prior written consent of Seller, there shall be no recordation of
either this Agreement or any memorandum hereof, or any affidavit pertaining hereto, and any such recordation of this Agreement or memorandum or affidavit by Purchaser without the prior written consent of Seller shall constitute a default hereunder
by Purchaser, whereupon Seller shall have the remedies set forth in Section 10.1 hereof. In addition to any such remedies, Purchaser shall be obligated to execute an instrument in recordable form releasing this Agreement or memorandum or
affidavit, and Purchaser’s obligations pursuant to this Section 12.14 shall survive any termination of this Agreement as a surviving obligation. 
  
 Section 12.15 Further Assurances. In addition to the acts and deeds recited herein and contemplated to be performed, executed and/or
delivered by either party at Closing, each party agrees to perform, execute and deliver, but without any obligation to incur any additional liability or expense, on or after the Closing any further deliveries and assurances as may be reasonably
necessary to consummate the transactions contemplated hereby or to further perfect the conveyance, transfer and assignment of the Property to Purchaser. 
  
 Section 12.16 Discharge of Obligations. The acceptance of the Deed by Purchaser shall be deemed to be a full performance and discharge of
every representation and warranty made by Seller herein and every agreement and obligation on the part of Seller to be performed pursuant to the provisions of this Agreement, except those which are herein specifically stated to survive Closing.

 Section 12.17 ERISA. Under no circumstances shall Purchaser have the right to assign this
Agreement to any person or entity owned or controlled by an employee benefit plan if Seller’s sale of the Property to such person or entity would, in the reasonable opinion of Seller’s ERISA advisors or consultants, create or otherwise
cause a “prohibited transaction” under ERISA. In the event Purchaser assigns this Agreement or transfers any ownership interest in Purchaser, and such assignment or transfer would make the consummation of the transaction hereunder a
“prohibited transaction” under ERISA and necessitate the termination of this Agreement then, notwithstanding any contrary provision which may be contained herein, Seller shall have the right to terminate this Agreement. 
  
 Section 12.18 No Third Party Beneficiary. The provisions of
this Agreement and of the documents to be executed and delivered at Closing are and will be for the benefit of Seller and Purchaser only and are not for the benefit of any third party, and accordingly, no third party shall have the right to enforce
the provisions of this Agreement or of the documents to be executed and delivered at Closing, except that a tenant of the Property may enforce Purchaser’s indemnity obligation under Section 4.10 hereof. 
  
 Section 12.19 Reporting Person. Purchaser and Seller hereby
designate the Title Company as the “reporting person” pursuant to the provisions of Section 6045(e) of the Internal Revenue Code of 1986, as amended. 
  

Section 12.20 Mandatory Arbitration. The parties have agreed to submit disputes to mandatory arbitration in accordance with the
provisions of Exhibit I attached hereto and made a part hereof for all purposes. Each of Seller and Purchaser waives the right to commence an action in connection with this Agreement in any court and expressly agrees to be bound by the
decision of the arbitrator determined in Exhibit I attached hereto. The waiver of this Section 12.20 will not prevent Seller or Purchaser from commencing an action in any court for the sole purposes of enforcing the obligation of the
other party to submit to binding arbitration or the enforcement of an award granted by arbitration herein, or as expressly permitted by Section 10.1 hereof. 
  
 Section 12.21 Cooperation with Purchaser’s Auditors and SEC Filing Requirements. Seller acknowledges that
subsequent to Closing, Purchaser may need to conduct an audit of operating records for the Property for the two (2) calendar years immediately prior to the year in which the Closing occurs and for the portion of calendar year 2004 that Seller owned
the Property in order for Purchaser (or Wells Operating Partnership, L.P. or Wells Real Estate Investment Trust, Inc.) to file its (or their) Form 8-K required by the Securities and Exchange Commission. Seller agrees to reasonably cooperate with
Purchaser or Purchaser’s auditor, without Seller incurring any additional costs, and make available for review any information relating to the Property that was not previously delivered to Purchaser that is necessary for such audit, to the
extent such information is in the possession of Seller and in the format that Seller has maintained such information. In addition, upon written request by Purchaser, Seller agrees to provide to Purchaser’s auditor a letter of representation in
the form attached hereto as Exhibit O.  
  
 Section
12.22 Soil Disclosure. Pursuant to Section 42-608(b) of the District of Columbia Code, Purchaser is hereby advised by Seller that the characteristic of the soil of the 

 Property as described by the Soil Conservation Service of the United States Department of Agriculture in the Soil Survey
of the District of Columbia published in 1976, as the same may be amended from time to time, and as shown on the Soil Maps of the District of Columbia at the back of that publication, is that of “Urban Land” (Ub). For further information,
Purchaser can contact a soil testing laboratory, the District of Columbia Department of Environmental Services, or the Soil Conservation Service of the United States Department of Agriculture.  
  
 Section 12.23 UST Disclosure. In accordance with the
requirements of the District of Columbia Underground Storage Tank Management Act of 1990, as amended by the District of Columbia Underground Storage Tank Management Act of 1990 Amendment Act of 1992 (D.C. Code Section 8-113.1 et seq.)
and the D.C. Underground Storage Tank Regulations, 20 DCMR Chapters 55-70, Seller has knowledge, and has informed Purchaser, that during Seller’s ownership of the Property, no underground storage tanks were removed from the Property.

  
 Section 12.24 Underground Facilities Compliance.
In accordance with the District of Columbia Underground Facilities Protection Act, as amended (D.C. Code Sections 34-2701 et seq.) (the “Underground Facilities Act”), Purchaser shall be solely responsible for providing any
notifications required therein prior to performing any excavation on the Property pursuant to Article 4 above, and any work performed by or on behalf of Purchaser at the Property pursuant to Article 4 shall be strictly in accordance with the
Underground Facilities Act. Purchaser hereby indemnifies Seller against and holds Seller harmless from any and all liability, cost, damage or expense (including attorneys fees) suffered or incurred by Seller on account of a violation by Purchaser of
the foregoing requirements.
