approvals relate to the Real Property or the Tangible Personal Property as opposed to other property of Seller not transferred in whole or in part to Purchaser pursuant to this Agreement (collectively, the “Intangible Property”).

  
 1.2 Property Defined. The Land, the
Improvements, the Tangible Personal Property, the Leases and the Intangible Property are hereinafter sometimes referred to collectively as the “Property.” 
  
 1.3 Permitted Exceptions. The Property shall be conveyed subject to the matters which are, or are deemed to
be, Permitted Exceptions pursuant to Article 2 hereof (collectively, the “Permitted Exceptions”). 
  
 1.4 Purchase Price. Seller is to sell and Purchaser is to purchase the Property for a total purchase price of FIFTY-NINE MILLION FIVE
HUNDRED THOUSAND DOLLARS ($59,500,000.00) (the “Purchase Price”). This Agreement, and Purchaser’s obligations hereunder, are not contingent on any financing, including any financing secured upon all or any portion of the
Premises, or any part thereof, or secured on any interest in the Purchaser. 
  
 1.5 Payment of Purchase Price. The Purchase Price, as adjusted by prorations and adjustments as herein provided, shall be payable in full at the Closing in cash by wire transfer of immediately available
federal funds to a bank account of Commonwealth Land Title Company, a LandAmerica company, 888 West Sixth Street, Los Angeles, CA 90017; Attn: Don Hallman, Senior Vice President (the “Escrow Agent”) prior to the Closing

Closing. 
  
 1.6 Earnest Money. Within three (3)
Business Days following the Effective Date, Purchaser shall deposit with the office of Escrow Agent at 630 Third Avenue, 5th Floor, New York, New York 10017 the sum of Five Hundred Thousand Dollars ($500,000.00) (the “Initial Earnest Money”) in good funds, either by certified bank or cashier’s check or by wire transfer of
immediately available funds. Within three (3) Business Days following the Inspection Date, Purchaser shall deposit with the office of Escrow Agent the additional sum of Five Hundred Thousand Dollars ($500,000.00) (the “Additional
Earnest Money”; the Initial Earnest Money and the Additional Earnest Money shall be referred to herein as the “Earnest Money”) in good funds, either by certified bank or cashier’s check or by wire transfer of

the Initial Earnest Money within such three (3) Business Day period after the Effective Date, Seller shall be entitled to terminate this Agreement, by written notice to Purchaser, at any time after the expiration of such three (3) Business Day
period until the Initial 

 
Earnest Money is deposited with Escrow Agent and upon such termination neither party shall have any further rights, obligations or liabilities hereunder
except to the extent that any right, obligation or liability set forth herein expressly survives termination of this Agreement. Escrow Agent shall invest the Initial Earnest Money and the Additional Earnest Money, when received, pursuant to
Purchaser’s directions and in accordance with the terms and conditions of Article 10. All interest accruing and other income earned on such sum shall be for the account of Purchaser and shall become a part of the Earnest Money and shall
be distributed as Earnest Money in accordance with the terms of this Agreement. In any event, if Purchaser is entitled to have the Earnest Money returned to Purchaser pursuant to any provision of this Agreement, One Hundred Dollars ($100.00)
of the Earnest Money shall nevertheless be paid to Seller as good and sufficient consideration for entering into this Agreement. Time is of the essence for the delivery of the Earnest Money. 
  
 ARTICLE 2 
  
 TITLE AND SURVEY 
  
 2.1 Title Examination; Commitment for Title Insurance. Escrow
Agent, in its capacity as agent for Commonwealth Land Title Company, a LandAmerica company (the “Title Company”), has delivered to each of Purchaser and Seller (i) Title Company’s title commitment number NYLS. 104242-PA, having
an effective date of September 5, 2004 (the “Title Commitment”) covering the Real Property and (ii) copies of all recorded documents referenced as exceptions to title to the Real Property on the Title Commitment (the “Title
Documents”). In addition, Seller has delivered to Purchaser that certain existing ALTA survey of the Real Property (the “Existing Survey”) more particularly described on Exhibit E attached hereto. 
  
 2.2 Survey. Purchaser may, at its option and expense, employ a
reputable (determined in Purchaser’s good faith discretion) surveyor or surveying firm, licensed by the Commonwealth of Pennsylvania to (i) update the Existing Survey or (ii) to independently survey the Real Property and prepare and deliver to
Purchaser, the Title Company and Seller a survey thereof reflecting the total area of the Land, the location of all Improvements, recorded easements and encroachments, if any, located thereon and such other matters as may be requested by Purchaser,
which survey shall be certified to both Seller and Purchaser (such update of the Existing Survey or such independent survey is referred to herein as the “Survey”). Upon completion of the Survey, Purchaser shall deliver three (3)
prints of the Survey to Seller (provided that such delivery shall be made without any representation or warranty from Purchaser to Seller of any kind, including without limitation as to the accuracy or completeness thereof). 
  
 2.3 Title Objections; Cure of Title Objections. Purchaser shall
have until forty (40) days after the Effective Date (the “Title Objection Deadline”) to notify Seller, in writing, of such objections as Purchaser may have to the Title Commitment or the Survey, other than the Permitted Exceptions
described in clauses (a) through (d) of Section 2.4, which objections shall be made in one notice. Any item contained in the Title Commitment or any matter shown on the Survey to which Purchaser does not object on or before the Title Objection
Deadline (or if 

 
Purchaser elects not to obtain an update to the Existing Survey, all matters not shown on the Existing Survey that would be shown by an accurate, current
survey of the Real Property) shall also be deemed a “Permitted Exception”. In the event Purchaser shall notify Seller of objections to title or to matters shown on the Survey on or before the Title Objection Deadline, Seller shall have the
right, but not the obligation, to cure such objections. On or before the date that is five (5) Business Days after receipt of Purchaser’s written objections to the Title Commitment and the Survey, Seller shall notify Purchaser in writing
whether Seller elects to attempt to cure such objections (and Seller’s failure to provide such a notice shall be deemed an election by Seller not to cure any such objection). If Seller elects to attempt to cure, and provided that
Purchaser shall not have terminated this Agreement in accordance with Section 3.2 hereof, Seller shall use commercially reasonable efforts to attempt to remove, satisfy or cure the same (provided that, if such objections are not removed, Purchaser
can accept or reject such other satisfaction or cure in Purchaser’s sole discretion). For this purpose each of Seller and Purchaser shall be entitled to a reasonable extension of the Closing if additional time is required, but in no event shall
the extension extend for more than thirty (30) days in the aggregate beyond the initial Closing Date. If Seller elects (or is deemed to have elected) not to cure any valid objections specified in Purchaser’s notice, or if Seller fails or is
unable to effect a removal, satisfaction or cure prior to the Closing (or any date to which the Closing had been extended), Purchaser shall have the following options: (i) to accept a conveyance of the Property subject to the Permitted Exceptions,
specifically including any matter objected to by Purchaser which Seller is unwilling or unable to satisfy or cure, and without reduction of the Purchase Price; or (ii) to terminate this Agreement by sending written notice thereof to Seller, and upon
delivery of such notice of termination, this Agreement shall terminate and the Initial Earnest Money (and to the extent paid by Purchaser and received by Escrow Agent, the Additional Earnest Money) shall be immediately returned to Purchaser in
accordance with Section 1.6 of this Agreement, and thereafter neither party hereto shall have any further rights, obligations or liabilities hereunder except to the extent that any right, obligation or liability set forth herein expressly survives
termination of this Agreement. If Seller notifies Purchaser that Seller does not intend to attempt to cure any title objection, or if Seller is deemed to have elected not to cure any title objections, or if Seller notifies Purchaser of Seller’s
intent to cure any objection and Seller later notifies Purchaser that Seller has failed or will be unable to effect a cure thereof, Purchaser shall, within five (5) Business Days after receiving Seller’s notice, notify Seller in writing whether
Purchaser shall elect to accept the conveyance under clause (i) above or to terminate this Agreement under clause (ii) above (with Purchaser’s failure to provide such a notice deemed an election by Purchaser to terminate this Agreement under
clause (ii) above, in which event Purchaser shall be deemed to have given the written notice provided for in clause (ii) above). Notwithstanding anything contained herein to the contrary, Seller shall be obligated at the Closing to release (a) all
mortgages, security interests or deeds of trust of Seller (regardless of whether Purchaser objects to such item) and (b) all monetary liens and encumbrances arising by, through or under Seller recorded against the Property, which monetary liens and
encumbrances shall be deemed discharged by the compliance by Seller with any statutory bonding procedure that has the legal effect of removing the item as a lien on the Real Property, and if Seller fails to satisfy any such monetary lien or
encumbrance, Purchaser may elect to proceed with the Closing and deduct the amount thereof from the Purchase Price and cause such monetary lien or encumbrance to be satisfied with such deducted amounts. 

 2.4 Conveyance of Title. At the Closing, Seller shall convey and transfer the Property to
Purchaser. It shall be a condition to Purchaser’s obligation to close this transaction that title to the Real Property conveyed and transferred to Purchaser shall be such title to the Real Property as will enable the Title Company to issue to
Purchaser an extended coverage ALTA 1970 Form B Owner’s Policy of Title Insurance (or, if such form of title insurance is not available to be issued by the Title Company, the standard form of extended coverage Owner’s Policy of Title
Insurance in use in the Commonwealth of Pennsylvania), together with all endorsements available in the Commonwealth of Pennsylvania (for which Seller shall have no obligation to pay or provide any indemnifications or other similar agreements other
than a customary “gap” indemnity) and requested in writing by Purchaser from Title Company (a copy of which writing shall be provided simultaneously to Seller) on or before the expiration of the Title Objection Deadline (the “Title
Policy”) covering the Real Property, in the full amount of the Purchase Price, subject to the following matters, which shall be deemed to be Permitted Exceptions: 
  
 (a) the rights of tenants, subtenants and licensees as tenants, subtenants and licensees, respectively,
only, under the Leases described in Exhibit D hereto and any new Leases entered into between the Effective Date and the Closing and (if required) approved by Purchaser in accordance with the terms of this Agreement; 
  
 (b) the lien of all ad valorem real estate taxes and
assessments not yet due and payable as of the Closing Date, subject to adjustment as herein provided; 
  
 (c) local, state and federal laws, ordinances or governmental regulations, including but not limited to, building, zoning and land use
laws, ordinances and regulations, now or hereafter in effect relating to the Real Property; 
  
 (d) all matters shown in Items 1 through 8 and 10 in Schedule B, Section 2, of the Title Commitment; 
  
 (e) additional items, if any, appearing of record or shown
on the Survey, except with respect to such items objected to by Purchaser pursuant to the provisions of Section 2.3 hereof which Purchaser elects under Section 2.3 not to accept the conveyance of the Property; and 
  
 (f) additional items, if any, approved by Purchaser pursuant
to Section 2.6 hereof. 
  
 2.5 Pre-Closing “Gap”
Title Defects. Whether or not Purchaser shall have furnished to Seller any notice of title objections pursuant to the foregoing provisions of this Agreement, Purchaser may, at or prior to the Closing, notify Seller in writing of any
objections to title first raised by the Title Company or the Surveyor and first arising between the effective date of the Title Commitment and the Closing; provided, however, that Purchaser must notify Seller of any such objections
within five (5) Business Days of Purchaser’s first receipt of the 

 
updated title commitment, updated survey or other document, whichever first provides notice of the condition giving rise to any such objection. With respect
to any objections to title set forth in such notice, Seller shall have the same option to cure and Purchaser shall have the same option to accept title subject to such matters or to terminate this Agreement as those which apply to any notice of
objections made by Purchaser on or before the Title Objection Deadline. If Seller elects to attempt to cure any such matters, each of Seller and Purchaser shall have the right, at its election, to extend the date for the Closing by a reasonable
additional time to effect such a cure (or to respond thereto), but in no event shall the Closing be extended for more than thirty (30) days in the aggregate beyond the initial Closing Date. 
  
 2.6 Seller’s Covenant Not to Encumber. Seller agrees that,
between the Effective Date and the Closing Date, Seller will not sell, assign, rent, convey (absolutely or as security), grant a security interest and, or otherwise encumber or dispose of, the Property (or any part thereof or estate therein) in any
manner that will survive the Closing (or which, in any way, will be an exception to the Title Policy), except as approved in writing by Purchaser (in its sole discretion) or as expressly provided in this Agreement. Notwithstanding the foregoing,
Seller shall have the right to (i) execute or enter into any new Lease in the manner described in Section 5.4(b) hereof, and (ii) amend or enter into Service Contracts (defined below) in the manner described in Section 5.4(g) hereof. 
  
 ARTICLE 3 
  
 INSPECTION PERIOD 
  
 3.1 Right of Inspection. 
  
 (a) Beginning upon the Effective Date and continuing until that date which
is forty (40) days after the Effective Date (the “Inspection Date”), Purchaser and its agents, engineers, surveyors, appraisers, auditors and other representatives (collectively, “Purchaser’s Agents”) shall
have the right to enter upon the Real Property to physically examine, survey, obtain engineering inspections, test, appraise, and otherwise make investigations and examinations of the physical condition of the Property, and to examine at such place
or places at the Real Property, in the offices of the property manager (“Property Manager”) at the Property, any operating files maintained by Seller or the Property Manager in connection with the leasing, maintenance, operation,
ownership and/or management of the Property (including without limitation the physical condition and use, availability and adequacy of utilities, access, zoning, compliance with applicable laws, environmental conditions, engineering and structural
matters, title and survey matters, and any other matters Purchaser deems necessary or appropriate for purposes of consummating this transaction), including, without limitation, the Leases, lease files, service contracts, bills, invoices, receipts
and other general records relating to the income and expenses of the Property, correspondence, surveys, plans and specifications, warranties for services and materials provided to the Property and similar materials, but excluding Seller’s
financial projections and appraisals (collectively, “Inspections”). Notwithstanding anything in this Section 3.1 to the contrary, at all times during the entire term of this Agreement, Purchaser shall be granted access to the Real
Property as such access is requested by Purchaser (and such access shall be subject to the terms and conditions set forth in this Agreement). 

 (b) Purchaser understands and agrees that any on-site inspections of the Real Property shall be conducted
upon one (1) Business Day’s advance notice to Seller (and, at Seller’s election, in the presence of Seller or its representative) and subject to the rights of the Tenants under the Leases. All inspections shall occur at reasonable times
agreed upon by Seller and Purchaser (provided that normal business hours shall be deemed reasonable) and shall be conducted so as not to interfere unreasonably with use of the Real Property by the Tenants. In conducting any such inspections
Purchaser and Purchaser’s Agents shall execute and comply with the terms of any confidentiality agreements that may be required by any of the Tenants pursuant to the terms of their respective Leases and shall otherwise comply with the terms of
any of the Leases regarding access by the landlord to Tenant space in the Improvements and any other terms of the Leases that are applicable to any such inspections and the entry into any space of the Tenants in the Improvements. In addition,
Purchaser’s Agents shall, prior to entering onto the Real Property, furnish to Seller and the Property Manager a certificate of insurance evidencing standard commercial general liability insurance with at least One Million Dollars
($1,000,000.00) combined, single-limit, liability coverage providing coverage to Seller and the Property Manager (as additional insureds), for any personal injury or damage to property that may occur as a result of or in connection with the
activities of Purchaser’s Agents on the Real Property. 
  
 (c) If, prior to the Inspection Date, Purchaser desires to do any invasive testing, sampling or drilling of the Real Property, Purchaser shall do so only after (i) notifying Seller and obtaining Seller’s prior written consent thereto,
which consent may be granted or withheld in Seller’s sole discretion, and (ii) obtaining all consents and satisfying all other conditions, if any, which are required for such work under the Leases. Purchaser shall not conduct any invasive
testing, sampling or drilling after the Inspection Date. Purchaser shall comply with all applicable laws and regulations in performing any such work and may be subject to any terms and conditions imposed by Seller in its sole discretion. Any samples
taken for analysis shall be evenly split between Purchaser and Seller. Purchaser shall promptly repair any affected part of the Real Property which is subjected to any such invasive testing, sampling, or drilling, or otherwise affected by
Purchaser’s inspection, to substantially the same condition which existed prior to any such inspections, tests, sampling or drilling, at Purchaser’s sole cost and expense, and in a lien free manner. Purchaser will immediately deliver to
Seller copies of all final reports received by Purchaser relating to any inspections of the Real Property (provided that such furnishing of such reports shall be made without any representation or warranty from Purchaser to Seller of any kind,
including without limitation as to the accuracy or completeness thereof). 
  
 (d) Purchaser agrees to indemnify against and hold Seller harmless from any claim for liabilities, costs, expenses (including reasonable attorneys’ fees actually incurred), damages or injuries (collectively,
“Claims, Losses, Damages and Expenses”) arising out of or resulting from the inspection of the Property by Purchaser or Purchaser’s Agents; provided, however that notwithstanding any provision of this Agreement to
the contrary, (i) the foregoing 

 
indemnity shall not apply to any Claims, Losses, Damages and Expenses suffered by Seller to the extent the same shall result from (A) the negligence or
willful misconduct of Seller, the Property Manager, or any of their agents, employees or contractors or (B) provided Purchaser has complied with the provisions of Section 3.1(c) above, any Hazardous Materials or dangerous or defective condition then
existing at the Real Property (the existence and location of which have not been previously disclosed in writing by Seller) that is discovered during any such inspection (provided that Purchaser will use commercially reasonable efforts to minimize
any Claims, Losses, Damages and Expenses resulting from such discovery, and (ii) in no case shall Seller be entitled to recover under such indemnity any lost profits, lost revenues, damages for lost opportunities or any other form of consequential
damage; provided further that, notwithstanding anything to the contrary in this Agreement, such obligation to indemnify and hold harmless Seller set forth in this Section 3.1(d) shall survive the Closing or any termination of this Agreement.

  
 (e) Purchaser may, as part of its investigation of the
Property, obtain a certificate from the Department of Licenses and Inspections of the City and County of Philadelphia, Pennsylvania, with respect to whether any uncorrected notices of violations of the Code of Philadelphia, Pennsylvania, exist of
record with respect to the Improvements. In addition, Purchaser may, with the prior written consent of Seller, which such consent shall be in Seller’s reasonable discretion, contact any governmental or quasi-governmental office, agency or
official, including without limitation any office, agency or official of City and County of Philadelphia, Pennsylvania or the Commonwealth of Pennsylvania (“Governmental Agencies”), including without limitation in connection with
(i) the environmental condition and history of the Property and (ii) all land use entitlements, development rights, licenses, permits, local, state and federal laws, ordinances or governmental regulations, including but not limited to, building,
zoning and land use laws, ordinances and regulations, now or hereafter applicable or relating to the Real Property; provided that, Purchaser shall provide Seller with (i) two (2) Business Days prior written notice of the time, date and
location of any such contacts with Governmental Agencies (provided further that, in lieu of such written notice, Purchaser may provide actual oral (including, without limitation, telephonic) notice to W. Alan Long so long as such oral notice is made
via a direct conversation and not via a voice message); (ii) a list of all topics Purchaser wishes to make of such Governmental Agencies; and (iii) an opportunity to participate therein; provided, further, that Purchaser shall
not, except as otherwise required by law or a court of competent jurisdiction, disclose to any Governmental Agency (A) that Purchaser is a prospective purchaser of the Property (but Purchaser may disclose that Purchaser is a prospective capital
investor in the Property) or (B) the Purchase Price. 
  
 (f) On or
before five (5) Business Days after the Effective Date, Seller shall deliver to Purchaser the following: (i) the most recent rent roll statement (the “Rent Roll”) with respect to the Property prepared by Seller or Property Manager,
certified as true and correct by the Seller and the Property Manager to Purchaser as of the Effective Date; (ii) copies of all Leases referenced on the Rent Roll and copies of any subleases or amendments relating thereto and copies of all Tenant
correspondence in the possession of Seller, any Affiliate of Seller or the Property Manager (which Leases and correspondence will be made available at the office of the Property Manager at the Real Property and not delivered to Purchaser); (iii) any
surveys of the 

 
real property in Seller’s (or Property Manager’s) possession; (iv) copies of all contracts described in Exhibit F, attached hereto and

cause the direction of the management and policies of an entity, whether through the ownership of voting securities, by contract or otherwise. 
  
 (g) Purchaser, as part of its investigation of the Property, at its sole cost and expense, may obtain on or before the Inspection Date, an audit letter in
the form of Exhibit Y attached hereto (the “Operational Audit Letter”), together with certified copies of the Statement (as defined in the Operational Audit Letter) and any other documents reasonably requested by Purchaser in
connection therewith. Seller shall use commercially reasonable efforts to cooperate with Purchaser’s efforts to obtain the Operational Audit Letter. 
  
 3.2 Right of Termination. Seller agrees that in the event Purchaser determines, in Purchaser’s sole discretion, that it does not wish
to acquire the Property for any reason or no reason, then Purchaser shall have the right to terminate this Agreement by giving written notice thereof to Seller before 5:00 p.m. (New York, New York local time) on or before the expiration of the
Inspection Period. Upon any such termination of this Agreement pursuant to Purchaser’s rights under this Section 3.2, the Earnest Money (to the extent paid by Purchaser and received by the Escrow Agent) shall be immediately returned to
Purchaser in accordance with Section 1.6 hereof, and Purchaser and Seller shall have no further rights and obligations hereunder except those which expressly survive termination of this Agreement. If Purchaser fails to give Seller timely notice on
or before the expiration of the Inspection Period of Purchaser’s election to proceed with the acquisition of the Property pursuant to this Agreement, then Purchaser shall be deemed to have elected to terminate this Agreement pursuant to this
Section 3.2. Time is of the essence with respect to the provisions of this Section 3.2. The period commencing on the Effective Date and ending on the Inspection Date is sometimes referred to herein as the “Inspection Period”.

 4.1 Time and Place. The consummation of the transaction contemplated hereby (“Closing”) shall be held without the necessity
of any parties to be physically present, at the offices of the Escrow Agent, at 10:00 a.m. (Pacific Standard Time) on that date which is sixty (60) days after the Effective Date (or such extended date as may be provided under other provisions of
this Agreement). At the Closing, Seller and Purchaser shall perform the obligations set forth in, respectively, Section 4.2 and Section 4.3. The Closing may be held at such other place, by escrow via the Title Company, or such earlier time and date
as Seller and Purchaser shall mutually approve. The date on which the Closing is scheduled to occur hereunder (or, if earlier, the date on which the Closing occurs) is sometimes referred to herein as the “Closing Date”. Seller and
Purchaser shall conduct a “pre-closing” on the Business Day immediately preceding the Closing Date pursuant to which Seller and Purchaser shall deposit in escrow with Escrow Agent or other escrow agent agreed upon by Seller and Purchaser
all documents required to be executed, and all other items required to be delivered, as of the Closing Date pending the actual Closing. 
  
 4.2 Seller’s Obligations at Closing. At the Closing, Seller shall: 
  
 (a) cause PAMI to deliver to Purchaser a duly executed special warranty deed in the form attached hereto as Exhibit G

otherwise; 
  
 (b) deliver to Purchaser a duly executed bill of
sale attached hereto as Exhibit H and incorporated herein by this reference, conveying the Tangible Personal Property and Intangible Personal Property with special warranty of title but subject to the limitations set forth in Section 9.2;

Assignment and Assumption of Leases for the Property in the form attached hereto as Exhibit I and incorporated herein by this reference (the “Assignment and Assumption of Leases”) (which Assignment of Leases shall include an
assignment by Seller to Purchaser of all security deposits (the “Security Deposits”) (including letters of credit (the “LCs”) and other cash or non-cash security deposits); provided that, with respect to the LCs,
Seller shall deposit in escrow with Escrow Agent (“LC Escrow Agent”) funds equal to the lesser of: (i) the face amount of each LC or (ii) the amount which is to be available for draw under each LC pursuant to the Leases, after
giving effect to reductions in accordance with such Leases, as of the Closing Date (the “Escrow Dollar Deposit”) and, provided further, that, Seller (at its expense, unless payable by and collected from the applicable Tenant
under its Lease) shall (i) deposit such LCs in escrow with LC Escrow Agent along with, if the same are assignable, any such forms Seller was able to obtain pursuant to reasonable commercial efforts, necessary to effect such assignment to Purchaser,
or (ii) if not assignable, Seller shall use reasonable efforts to cause such LCs to be reissued (at no cost to 

 
Purchaser) naming Purchaser, as beneficiary at Closing. Upon the reissuance of any LC naming the Purchaser as beneficiary, that amount of the Escrow Dollar
Deposit relating to such LC shall be immediately delivered to Seller. If any LC cannot be reissued, or should Seller be unable to obtain any form necessary for assignment at or prior to Closing, each of Seller and Purchaser shall use its
commercially reasonable efforts to cause the reissuance or assignment of such LCs to Purchaser within sixty (60) days after the date of Closing, at which time LC Escrow Agent shall remit the Escrow Dollar Deposit in whole to Seller. As between
Purchase and Seller, Purchaser shall bear all risk of physical loss of the actual LC document or certificate with regard to the transfer of any LC to LC Escrow Agent upon Seller’s deposit of the same with LC Escrow Agent. The Assignment and
Assumption of Leases shall provide that (i) Purchaser shall assume, from and after the Closing Date, the landlord/lessor interest in and to the Leases, as amended or supplemented pursuant to this Agreement, (ii) Seller shall indemnify Purchaser and

Purchaser by Seller pursuant to this Agreement; 
  
 (d) deliver to
Purchaser a duly executed counterpart of an Assignment and Assumption of Designated Service Contracts for the Property in the form attached hereto as Exhibit J and incorporated herein by this reference, pursuant to which (i) Seller shall

(ii) Purchaser shall indemnify Seller and hold Seller harmless from and against any and all Claims, Losses, Damages and Expenses pertaining to the Designated Service Contracts or the other Intangible Property arising from events occurring from and

Closing Date (with appropriate modifications to reflect any changes therein or identifying any 

 
representation or warranty which is not, or no longer is, true and correct and explaining the state of facts giving rise to the change). The inclusion of any
change or exception in such certificate shall not prejudice Purchaser’s rights under this Agreement with respect to the subject matter of such change or exception. It is a condition to Purchaser’s obligation to close hereunder that the
underlying facts stated in the representations and warranties of Seller contained in this Agreement, and reaffirmed under such certificate, be true and correct in all material respects as of the Closing Date; 
  
 (g) deliver to Purchaser an updated Rent Roll, certified as true and correct
by the Seller and Property Manager to Purchaser as of the Closing Date (provided that such certification shall be deemed a representation and warranty of Seller subject to the limitations thereon set forth in Section 5.3); 
  
 (h) deliver to Purchaser such evidence as the Title Company may reasonably
require as to the authority of the person or persons executing documents on behalf of Seller; 
  
 (i) deliver to Purchaser an affidavit pursuant to Section 1445(b)(2) of the Internal Revenue Code of 1986, as amended (the “Code”) duly executed by Seller stating that Seller is not a “foreign

11.28 hereof, that in no event shall Seller or PAMI be required to indemnify the Title Company, Purchaser, or any other party pursuant to any such documents, or undertake any other material liability not expressly contemplated in this Agreement,
unless Seller or PAMI elects to do so in its sole discretion.

provided, however, that if Escrow Agent has not received the Purchase Price together with instructions from Purchaser to disburse such funds to Seller at or prior to 11:00 a.m. (New York, New York local time) on the Closing Date,
Seller shall be entitled to receive an additional sum equal to the amount of interest on the Purchase Price for each day that the Title Company has not received the Purchase Price together with instructions from Purchaser to disburse such funds to
Seller at or prior to 11:00 a.m. (New York, New York local time), accrued on a daily basis at the rate of ten percent (10%) per annum;

 (d) deliver such additional documents as shall be reasonably requested by the Title Company or required to consummate the transaction contemplated by this
Agreement, provided, however, that in no event shall Purchaser be required to undertake any other material liability not expressly contemplated in this Agreement, unless Purchaser elects to do so in its sole discretion. 
  
 4.4 Credits and Prorations. 
  
 (a) All income and expenses in connection with the operation of the Property
shall be apportioned, as of 11:59 p.m., on the date prior to the Closing Date, as if Purchaser were 

 
vested with title to the Property during the entire Closing Date, such that, except as otherwise expressly provided to the contrary in this Agreement, Seller
shall have the benefit of income and the burden of expenses for the day preceding the Closing Date and the Purchaser shall have the benefit of income and the burden of expenses for the Closing Date and thereafter. Items (1)-(4) below will be
prorated at the Closing utilizing the information known at that time. A post-closing “true-up” shall take place within one hundred twenty (120) days of the Closing Date to adjust the prorations of said items (3) and (4), if necessary, and
within a reasonable time to adjust the proration of said items (1) and (2), if necessary. Such prorated items shall include, without limitation, the following: 
  

(1) rents, additional rents, common area maintenance charges, charges for taxes and insurance premiums or for escalations thereof, if
any, property operating expense contributions, and other income of the Property (other than any unapplied Security Deposits) collected for the current month; 
  

(2) ad valorem taxes and assessments levied against the Property, which shall be prorated as set forth in Section 4.4(b)(2) hereof;

  
 (3) payments under the Designated Service
Contracts (and to the extent any rebate or concession payable to Seller under any Designated Service Contract has accrued before the Closing but has not been paid to Seller, Seller shall receive a credit for such accrued amounts at the Closing); and

  
 (4) gas, electricity and other utility
charges attributable to the Property for which Seller is liable, if any, such charges to be apportioned at the Closing on the basis of the most recent meter reading occurring prior to the Closing. 
  
 (b) Notwithstanding anything contained in the foregoing provisions:

  
 (1) At the Closing, Seller shall credit to
Purchaser a sum equal to the aggregate of the unapplied security and other deposits under the Leases which are in the form of cash. 
  
 (2) At the Closing, to the extent such deposits are transferred to Purchaser pursuant to Section 4.2(c) above, Purchaser shall credit to
the account of Seller all refundable cash or other deposits posted with utility companies serving the Real Property, or, at either party’s option, Purchaser shall contract directly with the utility companies and Seller shall be entitled to
receive and retain such refundable cash and deposits; provided that Purchaser and Seller will cooperate so that utility service to the Real Property is not interrupted. 
  
 (3) Any ad valorem taxes paid at or prior to the Closing shall be prorated based upon the amounts actually
paid for the current tax year. If all taxes and assessments for the current tax year have not been paid before the Closing, Seller shall be charged at the Closing an amount equal to that portion of such 

 
taxes and assessments which relates to the period before the Closing and Purchaser shall pay the taxes and assessments prior to their becoming delinquent.
Any such apportionment made with respect to a tax year for which the tax rate or assessed valuation, or both, have not yet been fixed shall be based upon the tax rate and/or assessed valuation last fixed. To the extent that the actual taxes and
assessments for the current tax year differ from the amount apportioned at the Closing, the parties shall make all necessary adjustments by appropriate payments between themselves following the Closing upon the availability of the final tax bills
(or upon the availability of reasonable evidence of such other amounts). 
  
 (4) Gas, electricity and other utility charges referred in Section 4.4(a)(4) above which are payable directly by any tenant to a third party shall not be apportioned hereunder, and Purchaser shall accept title subject
to any of such charges unpaid and Purchaser shall look solely to the tenant responsible therefor for the payment of the same. If Seller shall have paid any of such charges on behalf of any tenant, and shall not have been reimbursed therefor by the
time of the Closing, Purchaser shall credit to Seller an amount equal to all such charges which are non-delinquent (with respect to the reimbursement by such tenant) so paid by Seller. 
  
 (5) As to gas, electricity and other utility charges referred to in Section 4.4(a)(4) above, Seller may on
notice to Purchaser elect to pay one or more of all of such items accrued to the Closing Date directly to the person or entity entitled thereto (and, if Seller so elects, Seller shall make such payments prior to such amounts becoming delinquent),
and to the extent Seller so elects and the utility company agrees to look solely to Seller for payment of such item accrued to the Closing Date, such item shall not be apportioned hereunder, and Seller’s obligation to pay such item with respect
to the period prior to the Closing directly in such case shall survive the Closing. 
  
 (6) The Tangible Personal Property and the Intangible Personal Property are included in this sale, without further charge. 
  
 (7) Unpaid and delinquent rent, including, but not limited
to, base rent, common area maintenance charges, charges for taxes and insurance premiums or for escalations thereof, or property operating expense contributions collected by Seller and Purchaser after the Closing Date shall be delivered as follows:
(a) if Seller collects any unpaid or delinquent rent for the Real Property, Seller shall, within fifteen (15) days after the receipt thereof, deliver to Purchaser any such rent which Purchaser is entitled to hereunder relating to the date of the
Closing and any period thereafter, and (b) if Purchaser collects any unpaid or delinquent rent from the Real Property, Purchaser shall, within fifteen (15) days after the receipt thereof, deliver to Seller any such rent which Seller is entitled to
hereunder relating to the period prior to the Closing Date. With respect to each respective Tenant, Seller and Purchaser agree that all rent received by Seller or Purchaser 

 
after the Closing shall be applied first to current rentals for the month in which such rent is received, and then, any excess to delinquent rentals, if any,
in inverse order of maturity (i.e., rent shall be applied to delinquent rentals with the shortest delinquency period prior to application to delinquent rentals with a longer delinquency period). Purchaser will make a good faith effort after the
Closing to collect all rents in the usual course of Purchaser’s operation of the Real Property, but Purchaser will not be obligated to institute any lawsuit or other collection procedures (or to declare a default under any Lease) to collect
delinquent rents. In the event there are any delinquent rents as of the Closing Date and the same are not collected by Purchaser and paid to Seller within ninety (90) days after the Closing Date, Seller shall have the right, upon written notice to
Purchaser, to seek collection of such delinquent rents using commercially reasonable efforts, including litigation, and Seller agrees to identify itself in any correspondence with any such tenant and to notify such tenant that Seller is the prior
landlord and prior owner of the Real Property and that its actions are not the actions of the current landlord and current owner of the Real Property, and Seller shall not seek to evict or otherwise affect any tenant’s possession of its
premises or to place a lien upon such premises or upon any portion of the Property. 
  
 (8) Subsequent to the Closing, but no later than ninety (90) days after the Closing, Purchaser shall calculate the common area maintenance
charges, charges for taxes and insurance premiums or for escalations thereof, or property operating expense contributions (collectively, “Operating Expense Pass-Throughs”) to be actually charged to each of the Tenants for the period
of time commencing on January 1, 2005 and ending on the Closing Date (the “Pass Through Period”) and shall reconcile the Operating Expense Pass-Throughs reimbursements actually received from each such Tenant (collectively,
“Reimbursement Amounts”) for the Pass Through Period with such actual amounts incurred for such Operating Expense Pass-Throughs and shall prepare and present to Seller a reconciliation of the same (with reasonable supporting
documentation). Seller may inspect Purchaser’s books and records related to the Property to confirm such reconciliation. If the Reimbursement Amounts received from such Tenants for the Pass Through Period exceed the actual Operating Expense
Pass-Throughs chargeable to such Tenants for the Pass Through Period (“Excess Charges”), Purchaser shall refund such Excess Charges to the Tenants. If the Reimbursement Amounts received from the Tenants for the Pass Through Period
shall be exceeded by the actual Operating Expense Pass-Throughs chargeable to such Tenants for the Pass Through Period (“Excess Additional Rent Expenses”), Purchaser shall bill and in good faith attempt to collect such Excess
Additional Rent Expenses from the Tenants who owe such amounts and shall pay such Excess Additional Rent Expenses so collected to Seller within fifteen (15) days after the receipt thereof. Seller shall indemnify, defend and hold Purchaser harmless
from and against any and all Claims, Losses, Damages and Expenses resulting from any amounts required to be refunded or credited to Tenants under the Leases (or claims of Tenants with respect thereto) because any 

 
Reimbursement Amounts actually received by Seller for the calendar years preceding the Closing Date and that portion of the Pass Through Period exceeded
actual Operating Expense Pass Throughs for such respective periods (including such amounts arising from tax refunds received by Seller), and absent instruction by Purchaser to the contrary, Seller shall pay directly to such Tenants such amounts
which are payable to the Tenants under the Leases and deliver to Purchaser evidence of such payment. 
  
 (c) The provisions of this Section 4.4 shall survive the Closing. 
  

4.5 Closing Costs. Seller shall pay (a) the fees of any counsel representing Seller in connection with this transaction, (b) one-half
(1⁄2) of any escrow fee which may be charged by Escrow Agent or Title Company, (c) one-half (1⁄2) of all realty transfer taxes, documentary stamp taxes and similar charges relating to the transfer of the Property, and all of the foregoing

of the basic premium for the ALTA 1970B, or other form of Title Policy insuring title to the Land and Improvements in favor of Purchaser, but not the cost of any endorsements or enhancements to coverage and (g) the cost of the update to the Existing

($5,000) (“Survey Cost Cap”). 
  
 4.6

all of the following conditions, any or all of which may be waived in writing by Purchaser in its sole discretion:

 (ii) Seller shall exercise commercially reasonable efforts to obtain from each Tenant a Proposed Tenant Estoppel (in the form provided by

 5.3 Survival of Seller’s Representations and Warranties. The representations and
warranties of Seller set forth in Section 5.1, as updated by Seller’s Closing Certificate, shall survive the Closing until the date that is one hundred fifty (150) days after the Closing Date (the “Expiration Date”). No
claim for a breach of any representation or warranty of Seller shall be actionable or payable (a) unless the valid claims for all such breaches collectively aggregate Two Hundred Fifty Thousand Dollars ($250,000.00) or more, in which event the full
amount of such valid claims shall be actionable, up to but not exceeding the amount of the Cap (as defined below), and (b) unless written notice containing a reasonable description of the nature of such breach known to Purchaser shall have been
given by Purchaser to Seller prior to the Expiration Date. Seller shall be released from liability to Purchaser for any such claim to the extent Purchaser receives proceeds of or payment under an insurance policy, service contract or Lease
for such claim. As used herein, the term “Cap” shall mean the total aggregate amount of One Million Five Hundred Thousand and No/100 Dollars ($1,500,000.00). In no event shall Seller’s aggregate liability to
Purchaser for any and all breaches of any representation or warranty of Seller in this Agreement or Seller’s Closing Certificate exceed the amount of the Cap, and Purchaser hereby waives and disclaims any right to damages or compensation for
any and all such breaches in excess of the Cap. Any liability of Seller pursuant to this Section 5.3 shall be set off against the Purchase Price; provided, however, that, subject to the provisions of this Section 5.3, Purchaser shall have the right
to proceed against the proceeds of this transaction up to the Cap in order to provide Purchaser protection with respect to the availability of funds to provide for any claims for breach of representations and warranties of Seller. At Seller’s
request, Purchaser shall reimburse Seller for one-half (1/2) of the amount of any refund of transfer taxes actually received by Purchaser in connection with a claim made by Purchaser pursuant to this Section 5.3 after the deduction therefrom of (i)
the amount of such claim for which Purchaser has not received payment from Seller (whether or not such amount is in excess of the Cap) and (ii) all of the costs and expenses actually incurred by Purchaser in connection with such refund of transfer
taxes. 
  
 5.4 Covenants of Seller. Seller hereby
covenants with Purchaser, from the Effective Date until the Closing or earlier termination of this Agreement, as follows:

consistent with the manner in which Seller has operated and maintained the Real Property prior to the date hereof. 
  
 (b) Execution of New Leases. Except for any new Lease entered into between the Effective Date and the Closing, in accordance with the terms
set forth in Exhibit W attached hereto and incorporated herein by this reference, Seller shall not amend, terminate, grant concessions regarding, or enter into any Lease without Purchaser’s prior written consent, which consent shall not
be unreasonably withheld, conditioned or delayed prior to the Inspection Date (provided that, the non-compliance of such new Lease with the terms of Exhibit W shall be reasonable grounds for Purchaser’s denial of Purchaser’s
consent to such Lease) and thereafter, Purchaser may grant or withhold its consent in its sole discretion. If Purchaser fails to object or otherwise reply to Seller’s request for consent within five (5) Business Days after receipt of
Seller’s request and all information reasonably required in order to make an informed decision, Purchaser shall be deemed to have withheld its consent to such proposed action. 

 (c) Maintenance of Insurance. Seller shall keep the Improvements insured against loss or
damage (including rental loss) by fire and all risks covered by the Seller’s insurance in the same manner (i.e., with coverages for the same perils, deductibles in the same amount and with an insurer with a Best’s rating no lower than the
insurer providing such coverage on the Effective Date). 
  
 (d)
Enforcement and Administration of Existing Leases. Seller shall perform the landlord’s material obligations to the tenants under the Leases, enforce the material obligations of the tenants under the Leases and administer the
Leases in the ordinary course of business, in each case accordance with the current management standards of Seller, which activities may include (without limitation) the declaring of a default or an event of default under any of the Leases for the
failure of any tenant to pay or perform its obligations under its respective Lease and the processing of any request for assignment or subletting made by any tenant under its respective Lease. 
  
 (e) Tenant Estoppel Certificates. Seller will request, and use
reasonable efforts to obtain, from each tenant and each guarantor under the Existing Leases, the New Leases, and the Guarantees (collectively, the “Space Leases”) an estoppel certificate in accordance with the provisions of Section
4.6(d) (or, in the event necessary to comply with the express terms of any Space Lease, in such form as may be required by the terms of any such Space Lease or, if applicable, in the form set forth in or attached to such Space Lease); provided,
however, Seller shall be deemed to have complied with this Section 5.4 (e) if Seller obtains an estoppel certificate from (i) Tenants which, in the aggregate, occupy 80% of the rentable square feet of the Improvements that is subject to a Lease as
of the Inspection Date, and (ii) not less than six (6) of the eight (8) Major Tenants. 
  
 (f) Provide Copies of Notices. Seller shall furnish Purchaser with a copy of all written notices received by Seller from any governmental authority of any violation of any law, statute, ordinance,
regulation or order of any governmental or public authority relating to the Real Property within five (5) Business Days following Seller’s receipt thereof, but, if received by such date, in no event later than two (2) Business Days prior to the
Closing Date. 
  
 (g) Execution of New Contracts.
Seller shall not, without Purchaser’s prior written consent in each instance (which consent shall not be unreasonably withheld or delayed during the Inspection Period but which thereafter may be withheld in Purchaser’s sole discretion),
materially amend or terminate any of the Designated Service Contracts, or enter into any contract or agreement that will be an obligation affecting the Property or binding on Purchaser after the Closing, except that Seller may enter into, amend or
enforce (including enforcement by termination) Service Contracts in the ordinary course of business as reasonably necessary for the continued operation and maintenance of the Property, provided any new Service Contracts are terminable without cause,
liability or penalty on thirty (30) days notice. Prior to termination of the Inspection Period, Seller may enter into construction contracts for the 

 
construction of tenant improvements in accordance with the Leases designated on Exhibit D, which construction contracts shall be assigned by Seller
and assumed by Purchaser at Closing, and Purchaser shall reimburse Seller at Closing for any payments made by Seller under such contracts, provided that Seller gives Purchaser notice of any such construction contract entered into. Following
termination of the Inspection Period, Seller shall not enter into any construction contract without Purchaser’s prior written consent, which such consent shall not be unreasonably withheld, conditioned or delayed. 
  
 (h) Maintenance of Permits. Seller shall maintain in existence
all material licenses, permits and approvals applicable to Seller that are now in existence with respect to, and are required for, the ownership, operation or improvement of the Property, and are of a continuing nature. 
  
 5.5 Representations and Warranties of Purchaser. Purchaser
hereby makes the following representations and warranties to Seller as of the Effective Date: 
  
 (a) Organization and Authority. Purchaser has been duly organized and is validly existing as a limited liability company under the laws of the State of Maryland. Purchaser has the full right and
authority to enter into this Agreement and to purchase the Property pursuant hereto and to consummate or cause to be consummated the transactions contemplated herein. The person signing this Agreement on behalf of Purchaser is authorized to do so.
Neither the execution and delivery of this Agreement nor any other documents executed and delivered, or to be executed and delivered, by Purchaser in connection with the transactions described herein, will violate any provision of Purchaser’s
organizational documents or of any agreements, regulations, or laws to or by which Purchaser is bound. This Agreement has been duly authorized, executed and delivered by Purchaser, is a valid and binding obligation of Purchaser and is enforceable

Purchaser has obtained all consents and permissions (if any) related to the transactions herein contemplated and required under any contract, agreement or other instrument by which Purchaser is bound. 
  
 (c) Pending Actions. There is no action, suit, arbitration,
administrative or judicial administrative proceeding, or unsatisfied order or judgment pending or, to Purchaser’s knowledge, threatened against Purchaser or the transaction contemplated by this Agreement, which, if adversely determined, could
individually or in the aggregate have a material adverse effect on Purchaser’s ability to consummate the transaction contemplated herein. 
  
 (d) Financial Status. Purchaser has not made a general assignment for the benefit of its creditors, nor has Purchaser filed any bankruptcy,
reorganization, arrangement, insolvency or liquidation proceedings, or any other proceeding for the relief of debtors in general, nor has any such proceeding been instituted by or against Purchaser. The purchase of the Property will not render
Purchaser insolvent. 

 5.6 Survival of Purchaser’s Representations and Warranties. The representations and
warranties of Purchaser set forth in Section 5.5 shall survive the Closing. 
  
 5.7 Covenants of Purchaser. 
  
 (a) Purchaser hereby covenants with Seller that Purchaser shall deliver to Seller, immediately upon receipt by Purchaser, copies of any reports received by Purchaser in connection with any inspection of the
Property for the presence of Hazardous Materials (as defined in Section 5.1(l) hereof) (provided that the delivery of such copies shall be made without any representation or warranty from Purchaser to Seller of any kind, including without limitation
as to the accuracy or completeness thereof). Purchaser shall also deliver to Seller immediately upon receipt by Purchaser copies of any final engineering or property inspection reports and all other similar reports received by Purchaser relating to
any other inspections or evaluations of the Property conducted on Purchaser’s behalf, if any (provided that the delivery of such copies shall be made without any representation or warranty from Purchaser to Seller of any kind, including without
limitation as to the accuracy or completeness thereof). 
  
 (b)
“Designated Service Contracts” means (i) those certain Service Contracts which are assignable in accordance with their terms which Purchaser identifies by written notice delivered to Seller on or before the date that is twenty-five
(25) days from the Effective Date as the Service Contracts Purchaser elects Seller to assign at the Closing, and (ii) those Service Contracts (collectively, the “Must Take Service Contracts”) which are assignable in accordance with
their terms and which may not be terminated without cause or penalty, with thirty (30) days (or less) written notice, which include any construction contracts for tenant improvements pursuant to Leases, which Must Take Services Contracts are listed
on Exhibit X. Purchaser hereby covenants with Seller that on or before the date that is twenty-five (25) days from the Effective Date, Purchaser shall deliver written notice to Seller instructing which of the assignable Service Contracts
Purchaser desires for Seller to assign to Purchaser and which it does not. If Purchaser fails to timely deliver such notice, Purchaser shall be deemed to have chosen to have all assignable Service Contracts assigned to Purchaser, and all such
Service Contracts shall be deemed part of the “Designated Service Contracts.” At the Closing, Seller will cause the Service Contracts which Purchaser has elected not to have assigned to Purchaser (other than the Must Take Service
Contracts), by operation of the aforesaid notice on or before the Inspection Date, to be terminated at Seller’s expense, such termination to be effective within the time period provide for in the applicable service contract (or if no such time
period is provided, as promptly as practicable after the Closing Date). The provisions of this Section 5.7(b) shall survive the Closing. 

 ARTICLE 6 
  

DEFAULT 
  
 6.1 Default by Purchaser. If the sale of the Property as contemplated hereunder is not consummated due to Purchaser’s default in
its obligations hereunder (as opposed to a mere failure of a condition hereunder), then Seller shall be entitled, as its sole and exclusive remedy for such default, to terminate this Agreement and receive the entire Earnest Money (consisting of the
Initial Earnest Money and the Additional Earnest Money, in the total amount of One Million Dollars ($1,000,000.00) ) as liquidated damages for the breach of this Agreement and not as a penalty, it being agreed between the parties hereto that the
actual damages to Seller in the event of such breach are impractical to ascertain and the amount of the Earnest Money (both the Initial Earnest Money and the Additional Earnest Money) is a reasonable estimate thereof, Seller hereby expressly waiving
and relinquishing any and all other remedies at law or in equity. Seller’s right to receive the Earnest Money (both the Initial Earnest Money and the Additional Earnest Money) is intended not as a penalty, but as full liquidated
damages. The right to receive the Earnest Money (both the Initial Earnest Money and the Additional Earnest Money) as full liquidated damages is Seller’s sole and exclusive remedy in the event of default hereunder by Purchaser, and Seller
hereby waives and releases any right to (and hereby covenants that it shall not) sue Purchaser: (a) for specific performance of this Agreement, or (b) to recover any damages of any nature or description other than or in excess of the Earnest Money
(both the Initial Earnest Money and the Additional Earnest Money). Purchaser hereby waives and releases any right to (and hereby covenants that it shall not) sue Seller or seek or claim a refund of the Earnest Money (the Initial Earnest Money
or the Additional Earnest Money) (or any part thereof) on the grounds it is unreasonable in amount and exceeds Seller’s actual damages or that its retention by Seller constitutes a penalty and not agreed upon and reasonable liquidated
damages. This Section 6.1 is subject to Section 6.4 hereof. 
  
 6.2 Default by Seller. If the sale of the Property as contemplated hereunder is not consummated due to Seller’s default in its obligations hereunder (as opposed to a mere failure of a condition hereunder), then Purchaser
shall be entitled, as its sole remedy for such default, either (a) to receive the return of the Earnest Money to the extent paid by Purchaser and received by the Escrow Agent, which return shall operate to terminate this Agreement and release Seller
from any and all liability hereunder, or (b) within sixty (60) days after the earlier of such default or the Closing Date, enforce specific performance of PAMI’s sole obligation to deliver the deed and Seller’s obligation to execute and
deliver the documents required to convey the Property to Purchaser, it being understood and agreed that the remedy of specific performance shall not be available to enforce any other obligation of Seller hereunder. Purchaser expressly waives its
rights to seek damages in the event of Seller’s default hereunder; provided, however, that if Seller’s default constitutes a Intentional Seller Default (as hereinafter defined) and Purchaser makes the election described in
clause (a) above, then Purchaser shall also have the right to sue Seller to obtain reimbursement for Purchaser’s third-party out-of-pocket costs and expenses incurred in connection with this Agreement and the Property, including due diligence
costs, engineering and environmental review costs, and legal fees and expenses, in an amount up to, but not exceeding, the lesser of (i) One Hundred Fifty Thousand and No/100 Dollars ($150,000.00), or (ii) the actual costs and expenses (documented
by receipts, invoices or similar written evidence) incurred by Purchaser for such third-party out-of-pocket costs and expenses. In no event shall Seller or PAMI be liable for consequential, speculative, remote or punitive damages, and Purchaser
hereby waives any right to seek or collect any such consequential, speculative, 

 
remote or punitive damages. Purchaser shall be deemed to have elected to terminate this Agreement and receive back the Earnest Money then paid if Purchaser
fails to file suit for specific performance against Seller in a court having jurisdiction in the county and state in which the Real Property is located, on or before thirty (30) days following the date upon which the Closing was to have occurred.
“Intentional Seller Default” means any one or more of the following: (a) fraudulent misrepresentation, (b) criminal conduct (i.e. conduct that constitutes a felony under applicable law), or (c) an intentional and deliberate act or
omission of Seller taken on or after the Effective Date that is intended to result in, and does result in, the failure or inability (or substantial impairment of the ability) of Purchaser or Seller to consummate this Agreement or to satisfy the
conditions set forth in this Agreement. 
  
 6.3 Notice of
Default; Opportunity to Cure. Neither Seller nor Purchaser shall be deemed to be in default hereunder until and unless such party has been given written notice of its failure to comply with the terms hereof and thereafter does not
cure such failure within ten (10) Business Days after receipt of such notice; provided, however, that this Section 6.3 (i) shall not be applicable to Purchaser’s failure to deliver the Earnest Money or any portion thereof on the
date required hereunder or to a party’s failure to make any deliveries required of such party on the Closing Date and, accordingly, (ii) shall not have the effect of extending the Closing Date or the due date of any Earnest Money deposit
hereunder. 
  
 6.4 Recoverable Damages.
Notwithstanding Sections 6.1 and 6.2 hereof, in no event shall the provisions of Sections 6.1 and 6.2 limit the damages recoverable by either party against the other party due to the other party’s express obligation to indemnify such party
in accordance with Section 3.1(c) or Section 8 of this Agreement. 
  
 ARTICLE 7 
  
 RISK OF LOSS 
  
 7.1 Minor Damage. In the event of loss or damage to the Real
Property or any portion thereof which is not “major” (as hereinafter defined), this Agreement shall remain in full force and effect provided Seller performs any necessary repairs or, at Seller’s option, assigns to Purchaser all of
Seller’s right, title and interest to any claims and proceeds Seller may have with respect to any casualty insurance policies or, to the extent of the Purchase Price, condemnation awards relating to the premises in question. In the event
that Seller elects to perform repairs upon the Real Property, Seller shall use reasonable efforts to complete such repairs promptly, and the Closing Date shall be extended a reasonable time in order to allow for the completion of such repairs.
If Seller elects to assign a casualty claim to Purchaser, the Purchase Price shall be reduced by an amount equal to (i) the deductible amount under Seller’s insurance policy and (ii) the difference, if any, between the amount the cost to
repair or restore the portion of the Property in question and the proceeds of such insurance (or, in the case of an uninsured casualty, an amount equal to the cost to repair or restore the portion of the Property in question). Upon the
Closing, full risk of loss with respect to the Real Property shall pass to Purchaser. 

 7.2 Major Damage. In the event of a “major” loss or damage to the Real Property,
either Seller or Purchaser may terminate this Agreement by written notice to the other party, in which event the Earnest Money then paid by Purchaser shall be returned to Purchaser in accordance with Section 1.6; provided, however,
Purchaser shall not have the right to terminate this Agreement if such “major” loss or damage is caused by the negligence or intentional misconduct of Purchaser or Purchaser’s Agents. If neither Seller nor Purchaser elects to
terminate this Agreement within ten (10) days after Seller sends Purchaser written notice of the occurrence of major loss or damage, then Seller and Purchaser shall be deemed to have elected to proceed with the Closing, in which event Seller shall
assign to Purchaser all of Seller’s right, title and interest to any claims and proceeds Seller may have with respect to any casualty insurance policies or condemnation awards relating to the premises in question and the proceeds of such
insurance. If Seller elects to assign a casualty claim to Purchaser, the Purchase Price shall be reduced by an amount equal to (i) the deductible amount under Seller’s insurance policy and (ii) the difference, if any, between the amount
the cost to repair or restore the portion of the Property in question and the proceeds of such insurance (or, in the case of an uninsured casualty, an amount equal to the cost to repair or restore the portion of the Property in question).
Upon the Closing, full risk of loss with respect to the Real Property shall pass to Purchaser. 
  
 7.3 Definition of “Major” Loss or Damage. For purposes of Sections 7.1 and 7.2, “major” loss or damage refers to
the following: (i) loss or damage to the Real Property or any portion thereof such that the cost of repairing or restoring the Real Property to a condition substantially similar to the condition of the Real Property prior to the event of
damage would be, in the opinion of an architect selected by Seller and reasonably approved by Purchaser, equal to or greater than Two Million and No/100 Dollars ($2,000,000), (ii) any loss due to a condemnation to the Land and/or Improvements, and
(iii) in each case under the preceding clauses (i) and (ii), would entitle any tenant under any of the Space Leases to terminate its respective Space Lease. If Purchaser does not give notice to Seller of Purchaser’s reasons for
disapproving an architect within five (5) Business Days after receipt of notice of the proposed architect, Purchaser shall be deemed to have approved the architect selected by Seller.

 Other than such representations, warranties and covenants of Seller as are
expressly set forth in this Agreement, upon the Closing, Purchaser shall assume the risk that adverse matters, including but not limited to, construction defects and adverse physical and environmental conditions, may not have been revealed by
Purchaser’s investigations of the Property, and Purchaser, upon the Closing (except with respect to (i) Hazardous Materials released in violation of Environmental Laws by Seller or any of its partners’ respective officers, directors,
shareholders, agents, employees or contractors on, in under or about the Property and (ii) except for the representations, warranties and covenants of Seller as are expressly set forth in this Agreement, shall be deemed to have waived, relinquished
and released Seller (and Seller’s and its partners’ respective officers, directors, shareholders, employees and agents) from and against any and all claims, demands, causes of action (including causes of action in tort or under any
Environmental Law), losses, damages, liabilities (whether based on strict liability or otherwise), losses, damages, liabilities, costs and expenses (including attorneys’ fees and court costs) of any and every kind or character, known or
unknown, which Purchaser might have asserted or alleged against Seller (and Seller’s and its partners’ respective officers, directors, shareholders, employees and agents) at any time by reason of or arising out of any latent or patent
construction defects or physical conditions, violations of any applicable laws (including, without limitation, any environmental laws) and any and all other acts, omissions, events, circumstances or matters regarding the Property. The foregoing
shall not be interpreted to waive any claim of Purchaser with respect to any breach by Seller of any express representations and warranties made by Seller in Section 5.1 that expressly survive the Closing pursuant to Section 11.19. 
  
 9.3 Effect and Survival of Disclaimers. Seller and Purchaser
acknowledge that the provisions of this Article 9 are an integral part of this transaction and a material inducement to Seller to enter into this Agreement and that Seller would not enter into this Agreement but for the provisions of this Article

 ARTICLE 10 
  
 ESCROW AGENT 
  
 10.1 Investment of Earnest Money. Escrow Agent shall invest the Earnest Money pursuant to Purchaser’s reasonable directions in an interest bearing account at a commercial bank whose deposits are
insured by the Federal Deposit Insurance Corporation, and the interest and other income earned on the Earnest Money deposit will be deemed part of the Earnest Money. Escrow Agent shall promptly advise Seller and Purchaser of the investment of
the Earnest Money. However, Escrow Agent shall invest the Earnest Money only in such accounts as will allow Escrow Agent to disburse the Earnest Money upon five (5) days notice. 

 10.2 Payment at Closing. If the Closing takes place under this Agreement, Escrow Agent
shall deliver the Earnest Money to, or upon the instructions of, Seller on the Closing Date. 
  
 10.3 Payment on Demand. Upon receipt of any written certification from Seller or Purchaser claiming the Earnest Money pursuant to the provisions of this Agreement, Escrow Agent shall promptly forward a
copy thereof to the other such party (i.e., Purchaser or Seller, whichever did not claim the Earnest Money pursuant to such notice) and, except as otherwise set forth in this Agreement unless such other party within three (3) Business Days
thereafter notifies Escrow Agent of any objection to such requested disbursement of the Earnest Money, Escrow Agent shall disburse the Earnest Money to the party demanding the same and shall thereupon be released and discharged from any further duty
or obligation hereunder. 
  
 10.4 Exculpation of Escrow
Agent. It is agreed that the duties of Escrow Agent are herein specifically provided and are purely ministerial in nature, and that Escrow Agent shall incur no liability whatsoever except for its willful misconduct or negligence, so long as
Escrow Agent is acting in good faith. Seller and Purchaser do each hereby release Escrow Agent from any liability for any error of judgment or for any act done or omitted to be done by Escrow Agent in the good faith performance of its duties
hereunder and do each hereby indemnify Escrow Agent against, and agree to hold, save, and defend Escrow Agent harmless from, any costs, liabilities, and expenses incurred by Escrow Agent in serving as Escrow Agent hereunder and in faithfully
discharging its duties and obligations hereunder. 
  
 10.5
Stakeholder. Escrow Agent is acting as a stakeholder only with respect to the Earnest Money. If there is any dispute as to whether Escrow Agent is obligated to deliver the Earnest Money or as to whom the Earnest Money is to be
delivered, Escrow Agent may refuse to make any delivery and may continue to hold the Earnest Money until receipt by Escrow Agent of an authorization in writing, signed by both Seller and Purchaser, directing the disposition of the Earnest Money, or,
in the absence of such written authorization, until final determination of the rights of the parties in an appropriate judicial proceeding. If such written authorization is not given, or a proceeding for such determination is not begun,
within thirty (30) days of notice to Escrow Agent of such dispute, Escrow Agent may bring an appropriate action or proceeding for leave to deposit the Earnest Money in a court of competent jurisdiction pending such determination. Escrow Agent
shall be reimbursed for all costs and expenses of such action or proceeding, including, without limitation, reasonable attorneys’ fees and disbursements, by the party determined not to be entitled to the Earnest Money. Upon making
delivery of the Earnest Money in any of the manners herein provided, Escrow Agent shall have no further liability or obligation hereunder. 
  
 10.6 Interest. All interest and other income earned on the Earnest Money deposited with Escrow Agent hereunder shall be for the account of
Purchaser and shall be reported for income tax purposes as earnings of Purchaser.  
  
 10.7 Execution by Escrow Agent. Escrow Agent has executed this Agreement solely for the purpose of acknowledging and agreeing to the provisions of this Article 10. Escrow Agent’s consent to
any modification or amendment of this Agreement other than this Article 10 shall not be required. 

 ARTICLE 11 
  
 MISCELLANEOUS 
  
 11.1 Confidentiality. Except as otherwise required by law or a court of competent jurisdiction, each of Purchaser and Seller (and each of
their respective representatives) shall hold in strictest confidence all data and information obtained with respect to the other or its business, whether obtained before or after the execution and delivery of this Agreement, and shall not disclose
the same to others; provided, however, that it is understood and agreed that each of Purchaser and Seller may disclose such data and information to the employees, consultants, accountants, attorneys, constituent members and lenders (or
prospective lenders) of such party provided that such persons agree to treat such data and information confidentially. In the event this Agreement is terminated or Purchaser fails to perform hereunder, Purchaser shall promptly return to Seller any
statements, documents, schedules, exhibits, reports or other written information obtained from Seller and obtained by Purchaser (without any representation or warranty) in connection with this Agreement or the transaction contemplated herein. In the
event of a breach or threatened breach by a party hereto or its agents or representatives of this Section 11.1, the other party hereto shall be entitled to an injunction restraining such party or its agents or representatives from disclosing, in
whole or in part, such confidential information. Nothing herein shall be construed as prohibiting either party hereto from pursuing any other available remedy at law or in equity for such breach or threatened breach. The provisions of this Section
11.1 shall survive the Closing or any termination of this Agreement. 
  
 11.2 Public Disclosure. Except as may be required by applicable laws, prior to the Closing, neither Seller nor Purchaser shall make, issue or release a public announcement, press release, public statement or public
acknowledgment of the existence, or reveal publicly, the terms, conditions and status of the transaction provided for in this Agreement without the prior written consent of the other party as to the content and time of the release of and the media
in which such statement or announcement is to be made. Seller and Purchaser agree that any public announcement, press release, public statement or public acknowledgment of the transactions provided for in this Agreement, whether or not approved by
the other party and whether made prior to or after the Closing, shall not disclose the Purchase Price or other economic or financial terms of the transaction provided for in this Agreement. The provisions of the first sentence of this Section 11.2
shall not survive the Closing but that the provisions of the second sentence of this Section 11.2 shall survive the Closing. 
  
 11.3 Assignment. The terms, conditions and covenants of this Agreement shall be binding upon and shall inure to the benefit of the parties
and their respective nominees, successors, beneficiaries and permitted assignees. At Closing (or, with respect to a Permitted Assignee (defined below) which is a direct or indirect wholly-owned subsidiary of Purchaser, after the Inspection Date),
Purchaser may assign its rights under this Agreement upon the 

 
following conditions: (a) the assignee of Purchaser must be an Affiliate of Purchaser (such Affiliates, “Permitted Assignees”), (b) the
assignee of Purchaser shall assume all obligations of Purchaser hereunder, and (c) a copy of the fully executed written assignment and assumption agreement shall be delivered to Seller promptly following the full execution of the same. In the event
any such assignment to a Permitted Assignee, such Permitted Assignee shall be entitled to the benefit of and may enforce Seller’s covenants, agreements, representations and warranties hereunder, as if such Permitted Assignee were the original
Purchaser hereunder. Other than as set forth in this Section 11.3, neither Purchaser nor Seller shall have the right to assign this Agreement without the written consent of the other party hereto. Any transfer, directly or indirectly, of any stock,
partnership interest or other ownership interest in Purchaser without Seller’s written approval, except to a Permitted Assignee, shall also constitute a prohibited assignment by Purchaser under this Agreement. No transfer or assignment by
Purchaser shall release or relieve Purchaser of its obligations hereunder, including, but not limited to, those which survive Closing. 
  
 11.4 Notices. Any notice, request or other communication (a “notice”) required or permitted to be given hereunder shall be
in writing and shall be delivered by (i) hand or overnight courier (such as United Parcel Service or Federal Express) or mailed by United States registered or certified mail, return receipt requested, postage prepaid and addressed to each party at
its address as set forth below, or by facsimile transmission as set forth below. Any such notice shall be considered given on the date of such hand or courier delivery, delivery by such overnight courier, actual receipt via the United States
mail, or by the date of the electronic confirmation of such facsimile transmission, but the time period (if any is provided herein) in which to respond to such notice shall commence on the date of hand or overnight courier delivery or on the date
received following deposit in the United States mail as provided above. Rejection or other refusal to accept or inability to deliver because of changed address of which no notice was given shall be deemed to be receipt of the notice.
By giving at least five (5) days’ prior written notice thereof, any party may from time to time and at any time change its mailing address hereunder. Any notice of any party may be given by such party’s counsel. 
  
 The parties’ respective addresses for notice purposes are as follows.
Telephone and telecopy numbers are given for convenience of reference only. Notice by telephone or telecopy shall not be effective.
