ARTICLE 2 - AGREEMENT OF
PURCHASE AND SALE; PURCHASE PRICE



Section 2.1Agreement of Purchase and Sale. Seller agrees to sell, transfer, assign and convey to Buyer, and Buyer agrees to purchase, accept and assume subject to the terms and conditions stated herein, all of Sellers right, title and interest
in and to the Property.



Section 2.2Purchase
Price.



2.2.1Base Price.
Subject to the provisions of Section 2.2.2 below, Buyer shall pay Seller the purchase price of Two Hundred Ninety-Nine Million and NO/100 Dollars ($299,000,000.00) (Purchase Price) in immediately available funds at Closing.
The Purchase Price and such other funds as may be necessary to pay Buyers expenses hereunder, subject to closing adjustments, shall be deposited with the Escrow Agent on or before the Closing Date in accordance with this Agreement and paid to
Seller upon satisfaction of all conditions precedent to the Closing as described herein.



2.2.2Price Adjustment. Notwithstanding anything to the contrary provided herein, the Purchase Price shall be adjusted, as
of the expiration of the Due Diligence Period, based on the yield-to-maturity (the YTM) of the 10-year U.S. Treasury Note (T-Note) as published or announced on the date on which the Due Diligence Period expires
in The Wall Street Journal (Eastern Edition) as follows. For each change in the YTM of the T-Note of 10 or more (but less than 20) basis points from the starting index point of 4.24%, there will be a corresponding adjustment to the Purchase
Price equal to One Million Four Hundred Thousand Dollars ($1,400,000.00). In the event that the YTM of the T-Note increases, the adjustment to the Base Price will be negative. Conversely, in the event the YTM of the T-Note decreases, adjustment to
the Base Price will be positive. There will be no adjustment for changes of less than 10 basis points. Promptly after the expiration of the Due Diligence Period, provided that Buyer has not elected to terminate this Agreement as provided in
Section 3.6, Seller and Buyer shall execute an amendment to this Agreement substantially in the form of Exhibit B attached hereto, setting forth the Purchase Price as adjusted in accordance with this Section 2.2.2.



Section 2.3Deposit. Within three (3) business
days after the Effective Date, Buyer shall deposit via wire transfer the sum of Three Million and NO/100 Dollars ($3,000,000.00) in immediately available funds as a deposit (the Initial Deposit) with Escrow Agent whose address is
as indicated in Section 10.3. Provided that Buyer has not elected to terminate this Agreement as provided in Section 3.6, Buyer shall deposit via wire transfer an additional Seven Million and NO/100 Dollars ($7,000,000.00) (the
Additional Deposit; the Initial Deposit and the Additional Deposit, collectively, the Deposit) in immediately available funds with Escrow Agent by 5:00 p.m. Eastern Time on the last day of the Due Diligence
Period. The Deposit shall be non-refundable except as expressly provided in Sections 3.6, 4.2, 5.1, 8.1, 10.2 or elsewhere in this Agreement, and shall be held and delivered by Escrow Agent pursuant to the Escrow Agents standard
joint order escrow agreement modified only to conform to the requirements of this Agreement, and otherwise in accordance with the provisions of Article 5. Interest earned on the Deposit shall be considered part of the Deposit and shall be
deemed to have been earned by, and constitute income of, Buyer. Except as otherwise expressly set forth herein, the Deposit shall be applied against the Purchase Price on the Closing Date.



- 9 -



---

Section 2.4Independent Consideration. Contemporaneously with the execution and delivery of
this Agreement, Buyer has paid to Seller as further consideration for this Agreement, in cash, the sum of One Hundred Dollars ($100.00) (the Independent Consideration), in addition to the Deposit and the Purchase Price and
independent of any other consideration provided hereunder, which Independent Consideration is fully earned by Seller and is non-refundable under any circumstances.



Section 2.5Indivisible Economic Package. Buyer has no right to purchase, and Seller has no obligation to
sell, less than all of the Property, it being the express agreement and understanding of Buyer and Seller that, as a material inducement to Seller and Buyer to enter into this Agreement, Buyer has agreed to purchase, and Seller has agreed to sell,
all of the Property, subject to and in accordance with the terms and conditions hereof.



Section 2.6Assignment and Assumption of Obligations. At Closing, Seller agrees to assign to Buyer all of Sellers right, title and interest in, to and under the Leases, Contracts, Licenses and
Permits from and after the Closing Date. At Closing, Buyer agrees to assume and perform all of the covenants and obligations of Seller pursuant to the Leases, Contracts, Licenses and Permits which arise on or after the Closing Date. The provisions
of this Section 2.6 shall survive the Closing without limitation.

any Seller or any Affiliate of Seller, and (ii) any documents, materials or information which are subject to attorney/client, work product or similar privilege, which constitute attorney communications with respect to the purchase of the Property by
Seller, or which are subject to a confidentiality agreement signed by Seller; (b) Due Diligence Items shall not include any Excluded Property Records; and (c) Seller shall have no obligation or liability of any kind to Buyer as a result of Seller
not furnishing or making available to Buyer the Excluded Property Records.

Seller. Such notice shall describe the scope of the Due Diligence Buyer intends to conduct during Buyers access to the Real Property. Seller shall make reasonable efforts to have an agent available to accompany Buyer or any Licensee Parties,
and in all events Seller shall have the right to have a representative present during any visits to or inspections of any Real Property or any meetings or discussions with any Tenant by Buyer or any Licensee Parties. Buyer will conduct its Due
Diligence in a manner so as to minimize, to the extent reasonably possible to do so, any interference with the operations and occupancy of the Property and to minimize, to the extent reasonably possible to do so, any disturbance to the Tenant. Buyer
will not enter the Real Property or contact any Property Manager of the Real Property or any Governmental Entity without Sellers prior written consent, which consent shall not be unreasonably withheld or delayed. Neither Buyer nor any Licensee
Parties may contact the Tenant, other than through Jim Nixon or through such other parties as he may direct, without



- 11 -



---

Sellers prior written consent. In the event Buyer desires to conduct any physically intrusive Due Diligence, such as sampling of soils, other media,
building materials, or the like, Buyer will identify in writing exactly what procedures Buyer desires to perform and request Sellers express written consent. Seller may withhold or condition consent to any physically intrusive Due Diligence in
Sellers sole and absolute discretion. Upon receipt of Sellers written consent, Buyer and all Licensee Parties shall, in performing such Due Diligence, comply with the agreed upon procedures and with any and all laws, ordinances, rules,
and regulations applicable to the Property and will not engage in any activities which would violate any permit, license, or environmental law or regulation. Buyer will: (a) maintain comprehensive general liability (occurrence) insurance in an
amount of not less than $5,000,000 covering any accident arising in connection with the presence of Buyer or the other Licensee Parties on the Real Property or Improvements, and deliver a certificate of insurance, which names the Seller as
additional insureds thereunder verifying such coverage to Seller prior to entry upon the Real Property or Improvements; (b) promptly pay when due the costs of all entry and inspections and examinations done with regard to the Property; and (c)

partners, shareholders or members, as applicable, and the Property Manager from and against all losses, costs, damages, claims, and liabilities (whether arising out of injury or death to persons or damage to the Property or otherwise) including, but
not limited to, costs of remediation, restoration and other similar activities, mechanics and materialmens liens and attorneys fees, arising out of or in connection with Buyers Due Diligence, Buyers breach of its
obligations under Section 3.5 or Buyers or any Licensee Parties entry upon the Real Property, unless any of the same are caused solely by the gross negligence or willful misconduct of Seller, Sellers partners, shareholders
or members, as applicable, and/or the Property Manager. The provisions of this Section 3.4 shall survive the Closing or, if the purchase and sale is not consummated, any termination of this Agreement, and shall not be subject to the twelve
month limitation set forth in Section 6.2.



Section
3.5Confidentiality. Buyer agrees that any information obtained by Buyer or its attorneys, partners, accountants, lenders, Permitted Third Parties or Licensee Parties (collectively, the Permitted Outside Parties) in the
conduct of its Due Diligence shall be treated as confidential pursuant to Section 10.11 of this Agreement and shall be used only (i) by Buyer to evaluate its acquisition of the Property from Seller, (ii) by Buyer in furtherance of its efforts
to finance its acquisition of the Property, or (iii) by a Permitted Third Party to evaluate its acquisition of any portion of the Property or in furtherance of such partys efforts to finance such an acquisition (collectively, the
Permitted Purposes). Buyer further agrees that within its organization, or as to the Permitted Outside Parties, the Due Diligence Items will be disclosed and exhibited only to those persons within Buyers organization or to
those Permitted Outside Parties who are involved in one of the Permitted Purposes. Buyer further acknowledges that the Due Diligence Items and other information relating to the leasing arrangements between Seller and the Tenant are proprietary and
confidential in nature. Buyer agrees not to divulge the contents of such Due Diligence Items or any other information except in strict accordance with Sections 3.5 and 10.11 of this Agreement. In permitting Buyer and the Permitted
Outside Parties to review the Due Diligence Items and other information in furtherance of a Permitted Purpose,



- 12 -



---

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 by Seller and any such claims are expressly rejected by Seller and waived by Buyer and the Permitted Outside Parties, for whom, by its execution of this Agreement, Buyer is acting as an
agent with regard to such waiver. The provisions of this Section 3.5 shall survive the Closing without limitation.



Section 3.6Right to Terminate. Buyer, by giving Seller and Escrow Agent written notice on or before the end of the Due Diligence Period,
may terminate its obligations hereunder without further liability except as described in this Section 3.6 and in Sections 3.4, 3.5, 9.6, and 10.11, and in the event of such termination, the Deposit shall be returned to Buyer. If
before the end of the Due Diligence Period, Buyer fails to give Seller such written notice, then Buyer shall be deemed to have elected to waive its rights to terminate this Agreement and to have approved all of the matters described in Sections
3.1 and 3.2. If Buyer timely elects to terminate its obligations hereunder as described above, Buyer shall provide to Seller, promptly after receipt of a request from Seller, originals of all third party reports, studies and appraisals
relating to the Property in its possession, without representation or warranty and at no cost to Seller. The foregoing obligation shall survive any termination of this Agreement. Subject to the terms of this Agreement, Buyer, after the expiration of
the Due Diligence Period, may continue to conduct further physical Due Diligence or other examinations, inspections, tests, studies and investigations regarding the Property; provided, however, that except as otherwise expressly provided in
Sections 5.1 and 10.2.2 or elsewhere in this Agreement, in no event shall Buyer have any right to terminate or otherwise modify its obligations hereunder after the end of the Due Diligence Period as a result of any such further
physical Due Diligence or other examinations, inspections, tests, studies or investigations regarding the Property, and the provisions of this Article 3, including, without limitation, the indemnification provisions, shall continue to apply.



Section 3.7Lease Modifications. Seller
acknowledges that Buyers obligation to close the transaction contemplated hereby is conditioned upon Buyer and Tenant agreeing, on or prior to the expiration of the Due Diligence Period, upon the terms of such amendments to or modifications of
the Leases (collectively, the Lease Amendments) as may be mutually acceptable to Buyer and Tenant, including, without limitation, Tenants waiver of any and all options to purchase the Property. Each of the Lease Amendments
shall be executed by the applicable Seller and Tenant prior to the expiration of the Due Diligence Period (but shall not be effective until the Closing Date) so that the Leases being assigned to Buyer at Closing shall incorporate the modifications
set forth in the Lease Amendments.



Section 3.8Non-Tenant Estoppel Certificates. Seller shall use commercially reasonable efforts to obtain and deliver to Buyer, prior to the expiration of the Due Diligence Period, estoppel certificates from the following parties (collectively, the
Estoppel Parties): (i) the parties to any reciprocal easement agreement to which any of the Real Property is bound, and (ii) the association or other governing parties of any office park association of which any of the Real
Property is a part. A copy of each such estoppel certificate received by Seller shall be delivered by Seller to Buyer promptly after Seller receives such certificate from the Estoppel Parties. Obtaining such certificates shall not, however, be a
condition to the Closing, nor shall Seller incur any liability in connection with failing to obtain such certificates. Buyers sole remedy, if the estoppel certificates delivered by Seller to Buyer are unacceptable to Buyer for



- 13 -



---

any reason or if the estoppel certificates do not include certificates for all Estoppel Parties, is that Buyer may, by giving Seller written notice on or
before the end of the Due Diligence Period, terminate its obligations hereunder without further liability except as described in Sections 3.4, 3.5, 3.6, 9.6 and 10.11. If, before the end of the Due Diligence Period, Buyer fails to give
Seller such written notice, then Buyer shall be deemed to have elected to waive its right to terminate this Agreement pursuant to this Section 3.8. After the expiration of the Due Diligence Period, provided Buyer has not terminated this
Agreement, Seller shall continue to use reasonable efforts to obtain and deliver to Buyer estoppel certificates from the Estoppel Parties to the extent Seller has not previously delivered to Buyer estoppel certificates from such Estoppel Parties;
provided, however, in no event shall Buyer have any right to terminate its obligations hereunder after the end of the Due Diligence Period as a result of any estoppel certificates received or not received by Buyer after the end of the Due Diligence
Period.



ARTICLE 4 - TITLE AND SURVEY



Section 4.1Title to Real Property. Seller shall make available
to Buyer not later than fifteen (15) business days after the Effective Date (a) a current commitment or commitments to issue an ALTA (or TLTA, as appropriate) form owners policy or policies of title insurance with respect to the Property
issued by the Title Company in the amount of the Purchase Price showing Buyer as the proposed insured (collectively, the Title Commitments), (b) copies of all recorded documents referred to on Schedule B of the Title Commitments
as exceptions to coverage (the Title Documents), and (c) current surveys of the Land and Improvements (collectively, the Surveys).



Section 4.2Certain Exceptions to Title. Buyer shall have the right to object in writing to any title matters
which are disclosed in the Title Commitments or Surveys (herein collectively called Liens) within ten (10) days after the later of (i) the Effective Date, or (ii) the date of receipt of the last of the Title Commitments, the Title
Documents and Surveys. Unless Buyer shall timely object to the Liens, all such Liens which are set forth in the Title Commitments, Title Documents or Surveys are Permitted Exceptions; provided that any deed of trust, mortgage,
judgment, mechanics lien (unless such mechanics lien is being contested in good faith by Seller and insured or bonded over at Closing so that they do not appear on the Title Policy) and or tax liens (any of the foregoing, a
Monetary Lien) shall not be considered Permitted Exceptions hereunder and Seller shall be obligated to remove same at or prior to Closing hereunder (irrespective or whether Buyer has specifically objected thereto). Any exceptions
which are timely objected to by Buyer shall be herein collectively called the Title Objections. Except for any Monetary Liens which Seller is obligated to remove, Seller may elect (but shall not be obligated) to remove or cause to
be removed, or insured over, at its expense, any Title Objections, and shall be entitled to a reasonable adjournment of the Closing (not to exceed thirty (30) days) for the purpose of such removal, which removal will be deemed effected by the
issuance of title insurance eliminating or, subject to Buyers approval not to be unreasonably withheld or delayed, insuring against the effect of the Title Objections. Seller shall notify Buyer in writing within ten (10) days after receipt of
Buyers notice of Title Objections whether Seller elects to remove the same (Sellers Title Objection Response). If Seller is unable to remove or endorse over any Title Objections prior to the Closing, or if Seller
elects not to remove one or more Title Objections other than Monetary Liens, Buyer may elect, as its sole and exclusive remedy therefore, to either (a) terminate this Agreement by giving written notice

to Seller and Escrow Agent on or before the later of (i) three (3) business days after receipt of Sellers Title Objection Response, or (ii) the end of
the Due Diligence Period, in which event the Deposit shall be paid to Buyer and, thereafter, the parties shall have no further rights or obligations hereunder except for those obligations which expressly survive the termination of this Agreement as
set forth in Sections 3.4, 3.5, 3.6, 9.6 and 10.11, or (b) waive such Title Objections, in which event such Title Objections shall be deemed additional Permitted Exceptions and the Closing shall occur as herein provided
without any reduction of or credit against the Purchase Price. If before the end of the Due Diligence Period, Buyer fails to give Seller and Escrow Agent such written notice, then Buyer shall be deemed to have elected to waive such Title Objections
and its right to terminate this Agreement pursuant to this Section 4.2.



Section 4.3Title Insurance. At Closing, Seller shall cause the Title Company to issue to Buyer or to be irrevocably committed to issue to Buyer extended coverage ALTA (or TLTA, as applicable)
owners form title policies (the Title Policies), in the aggregate amount of the Purchase Price, insuring that fee simple title to the Real Property is vested in Buyer subject only to the Permitted Exceptions. Buyer shall be
entitled to request that the Title Company provide such endorsements (or amendments) to the Title Policy as Buyer may reasonably require, provided that (a) such endorsements (or amendments) shall be at no cost to, and shall impose no additional
liability on, Seller, (b) Buyers obligations under this Agreement shall not be conditioned upon Buyers ability to obtain such endorsements and, if Buyer is unable to obtain such endorsements, Buyer shall nevertheless be obligated to
proceed to close the transaction contemplated by this Agreement without reduction of or set off against the Purchase Price, and (c) the Closing shall not be delayed as a result of Buyers request.

Property. Unless otherwise specified in one or more of the subsections of this Section 6.1, all representations and warranties of Seller shall be deemed given on the Effective Date and on the Closing Date without there being any need for a
separate certificate or statement as of such date. Seller has not contracted to make a representation or warranty on the Closing Date precisely as stated in the text of the subsections of this Section 6.1 if the representation or warranty

forth exceptions to such representation or warranty as Seller may deem necessary for such representation or warranty to be accurate as of the Closing Date without such action being a breach of this Agreement unless the exclusion, exception or
qualification arose as a result of or constitutes a breach of an independent obligation of Seller appearing in this Agreement. If no such written exclusion, exception or qualification is

delivered, then as of the Closing Date, the representation or warranty shall be deemed given exactly as appears in the text of the subsection. If a written
exclusion, exception or qualification to one or more of such subsections is delivered before Closing and such exclusion, exception or qualification discloses a material, adverse change in the condition or value of the Property or would impose a
material financial obligation on Buyer, Buyer shall have the right to terminate this Agreement and receive a return of the Deposit and, thereafter, the parties shall have no further rights or obligations hereunder except for those obligations which
expressly survive the termination of this Agreement. If a written exclusion, exception or qualification to one or more of such subsections is delivered before Closing and Closing nevertheless occurs, then as of the Closing Date all such
representations and warranties shall be deemed given exactly as appears in the text of such subsection subject only to such exclusion, exception or qualification.

FORE agrees to indemnify, protect, and hold Buyer harmless against and from any and all damages, losses, liabilities, obligations, penalties, claims, litigation, demands, defenses, judgments, proceedings, costs, disbursements, or expenses which may
be imposed upon or incurred by or asserted against Buyer and arising from or out of any demand for unpaid taxes or a claim for lien issued by the Department pursuant to the Illinois law against either HP I, HP II or HP III related to the sale of the

survive the termination of this Agreement.



9.2.2Sellers Conditions to Closing. It shall constitute a condition precedent to Sellers obligation to consummate the Closing hereunder that that the following conditions shall have been satisfied as of the
Closing Date:



(a) Seller shall have obtained,
no later than February 18, 2005, a waiver of the Woodlands ROFOs from each of the parties entitled to exercise the same; provided, however, that Seller agrees to waive the foregoing condition so long as Buyer agrees to waive the condition set

All of the material representations, warranties, covenants, and agreements of Buyer contained herein shall be true and correct and/or shall have been performed, as the case may be, in all material respects.

Items): real estate and personal property taxes and assessments (subject to the terms of Section 9.5.2 below), utility bills (except as hereinafter provided), and collected Rents. Seller will be charged and credited for the amounts
of all of the Proration Items relating to the period up to and including the Proration Time, and Buyer will be charged and credited for all of the Proration Items relating to the period after the Proration Time. No prorations will be made in
relation to insurance premiums, and Sellers insurance policies will not be assigned to Buyer. Final readings and final billings for utilities, to the extent not paid directly by the Tenant, will be made if possible as of the Proration Time, in
which event no proration will be made at Closing with respect to utility bills.



- 29 -



---

9.5.2All ad valorem real estate and personal property taxes with respect to the
Property (to the extent not paid directly by the Tenant) shall be prorated as of the Proration Time without regard to when said taxes are payable, using the tax year of the applicable taxing authority, so that (i) any taxes assessed against the
Property and allocable to periods prior to the Proration Time shall be credited to Buyer (but only to the extent such taxes are not paid directly by the Tenant) and (ii) any taxes assessed against the Property and allocable to periods from and after
the Proration Time shall be the responsibility of Buyer. If the amount of any taxes to be prorated in accordance with this Section 9.5.2 is not then ascertainable, the adjustment thereof shall be predicated upon 100% of the most recent
ascertainable assessments and tax rates (and assuming, with respect to the Orlando Real Estate, that HP IV takes advantage of the maximum discount provided by the taxing municipality for early payment of real estate taxes). Seller and Buyer do
hereby further agree with regard to any proration for real estate taxes for which the final bill was not ascertainable as of the Proration Time, to reprorate said real estate taxes forthwith upon Buyers receipt of the actual tax bill for the
tax year in question. This covenant shall survive the Closing of this transaction. .



9.5.3With respect to the Leases, the following will be credited to Buyer at Closing as of the Proration Time: (i) all non-cash
lease, security or other deposits held by Seller, (ii) an amount equal to all current and future abatements, concessions or allowances granted to the Tenant under the Leases, (iii) an amount equal to unpaid tenant improvements and lease commissions
in connection with Leases, (iv) all prepaid rent and rent paid for the balance of the month of Closing, (v) all sums currently held by Seller pursuant to the terms of Leases as estimated deposits for tenants share of real estate taxes and
operating expenses for the period after Closing, (vi) all cash lease, security or other deposits made by Tenant under the Leases and interest thereon, if any, received, earned or required to have been earned prior to the Proration Time. Seller shall
not receive credit at Closing for any payments of rental obligations due, but not paid on the Proration Time from the Tenant under the terms of the Leases (Non-Credit Items). Following receipt by Seller or Buyer of any payments
from Tenant for which there is a Non-Credit Item in existence, such payments shall be distributed and/or remitted in the following order of priority: (i) to Buyer for rent and other Lease obligations due or accrued from such tenant from and after
the Proration Time and when, and only when, such rents and other Lease obligations have been paid in full to Buyer; then (ii) the balance to Seller to the extent of any such Non-Credit Items with respect to Tenant. If a Non-Credit Item due Seller is
not paid by Tenant within the later of (a) sixty (60) days after the Closing or (b) sixty (60) days after billing therefor, Seller shall have the right to attempt to effect collection by litigation or otherwise so long as Seller does not take any
action which would (x) affect Tenants right to occupy the leased premises or (y) terminate its Lease. Buyer shall cooperate with Seller in its efforts to collect Non-Credit Items but shall not be required to take any action against Tenant
which would affect Tenants right to occupy its leased premises or terminate its Lease.



9.5.4Buyer shall receive a credit against the Purchase Price at Closing for all payments, if any, due or owing under any Contracts
for periods prior to the Closing Date, which amounts shall be prorated as of the Proration Time. If Seller has paid any amounts under any Contracts for periods after the Proration Time, Buyer shall pay such amounts to Seller at Closing in addition
to the Purchase Price.



- 30 -



---

9.5.5Such preliminary estimated Closing prorations shall be set forth on a
preliminary closing statement to be prepared by Seller and submitted to Buyer for Buyers approval prior to the Closing Date (the Closing Statement). The Closing Statement, once agreed upon, shall be signed by Buyer and
Seller and delivered to the Escrow Agent for purposes of making the preliminary proration adjustment at Closing subject to the final cash settlement provided for below. The preliminary proration shall be paid at Closing by Buyer to Seller (if the
preliminary prorations result in a net credit to Seller) or by Seller to Buyer (if the preliminary prorations result in a net credit to Buyer) by increasing or reducing the cash to be delivered by Buyer in payment of the Purchase Price at the
Closing. If the actual amounts of the Proration Items are not known as of the Proration Time, the prorations will be made at Closing on the basis of the best evidence then available; thereafter, when actual figures are received (not to exceed 120
days after Closing), re-prorations will be made on the basis of the actual figures, and a final cash settlement will be made between Seller and Buyer. The provisions of this Section 9.5.1(a) will survive the Closing for a period of twelve
(12) months.



9.5.6Seller shall pay
(a) the cost of discharging any Monetary Liens affecting the Property, (b) one-half of the Escrow Agents escrow fee, (b) all of the costs associated with the issuance of the Title Commitments and Title Policy, other than the costs of any
endorsements Buyer may require in accordance with Section 4.3; (c) the cost of the Surveys, (d) State of Illinois and Lake County transfer taxes, Florida deed taxes, and (e) any additional costs and charges customarily charged to sellers in
accordance with common escrow practices in the county in which the Property is located, other than those costs and charges specifically required to be paid by Buyer hereunder. Buyer shall pay (a) one-half of the Escrow Agents escrow fee, (b)
the costs of any endorsements to the Title Policies that Buyer may require in accordance with Section 4.3, (c) the recording fees required in connection with the transfer of the Property to Buyer; and (d) any additional costs and charges
customarily charged to buyers in accordance with common escrow practices in the municipality in which the Property is located, other than those costs and charges specifically required to be paid by Seller hereunder.



Section 9.6Broker. Seller hereby represents and warrants to
Buyer that it did not employ or use any broker or finder to arrange or bring about this transaction. Buyer hereby represents and warrants to Seller that Buyer has not employed any broker with respect to this transaction, other than Broker, and that
there are no claims or rights for brokerage commissions or finders fees in connection with the transactions contemplated by this Agreement, other than the commission (Brokers Commission) required to be paid to Broker.
Provided that the sale of the Property has closed pursuant to the terms of this Agreement and that Seller has received the Purchase Price at Closing (subject to adjustment as provided herein), Seller shall pay the Brokers Commission, but in no
event shall Seller be obligated to pay more than $1,500,000.00 (the Commission Cap). Seller shall not be obligated to pay a brokerage commission to any other party in connection with the transaction contemplated hereby. If any
person brings a claim for a commission or finders fee based upon any contact, dealings, or communication with Seller in connection with the transactions contemplated by this Agreement, then Seller shall defend Buyer from such claim, and shall
indemnify Buyer and hold Buyer harmless from any and all costs, damages, claims, liabilities, or expenses (including, without limitation, reasonable attorneys fees and disbursements) incurred by Buyer with respect to the claim. If any person
brings a claim for a commission or finders fee based upon any contact, dealings, or communication with Buyer in connection with the transactions contemplated by this Agreement,



- 31 -

other than Broker (subject, however, to the Commission Cap), then Buyer shall defend Seller from such claim, and shall indemnify Seller and hold Seller
harmless from any and all costs, damages, claims, liabilities, or expenses (including, without limitation, reasonable attorneys fees and disbursements) incurred by Seller with respect to the claim. The provisions of this Section 9.6
shall survive the Closing or, if the purchase and sale is not consummated, any termination of this Agreement and shall not be subject to the twelve month limitation set forth in Section 6.2.



Section 9.7 Expenses. Except as provided in Sections 9.5 and
9.6, each party hereto shall pay its own expenses incurred in connection with this Agreement and the transactions contemplated hereby, including, without limitation, in the case of Buyer, all third-party engineering and environmental review
costs and all other Due Diligence costs.

MISCELLANEOUS



Section 10.1 Amendment and
Modification. Subject to applicable law, this Agreement may be amended, modified, or supplemented only by a written agreement signed by Buyer and Seller.



Section 10.2 Risk of Loss and Insurance Proceeds.



10.2.1Minor Loss. Buyer shall be bound to purchase the Property for the full Purchase Price as required by the terms hereof,
without regard to the occurrence or effect of any damage to or destruction of any of the Improvements or condemnation of any portion of the Real Property, provided that: (a) such damage or destruction or such partial condemnation would not give rise
to a termination right on behalf of Tenant pursuant to the applicable Lease, and (b) upon the Closing, there shall be a credit against the Purchase Price due hereunder equal to the amount of any insurance proceeds or condemnation awards collected by
the applicable Seller as a result of any such damage or destruction or condemnation, plus the amount of any insurance deductible, less any sums expended by such Seller toward the restoration or repair of the applicable Property or in collecting such
insurance proceeds or condemnation awards. If the proceeds or awards have not been collected as of the Closing, then such proceeds or awards shall be assigned to Buyer, except to the extent needed to reimburse the applicable Seller for sums expended
prior to the Closing to repair or restore the affected Property or to collect any such proceeds or awards.



10.2.2Major Loss. If such damage or destruction or condemnation as specified above would give rise to a termination right on
behalf of Tenant pursuant to the applicable Lease and Tenant does, in fact, terminate the applicable Lease, then Buyer may at its option, to be exercised by written notice to Seller within ten (10) business days of Sellers notice of the
Tenants termination of the applicable Lease, terminate this Agreement (and, if applicable, Buyer shall be entitled to a reasonable adjournment of the Closing Date to accommodate the time period allowed under the applicable Lease for Tenant to
exercise such termination right). Buyers failure to elect to terminate this Agreement within said ten (10) business day period shall be deemed an election by Buyer to consummate this purchase and sale transaction. If Buyer elects to terminate
this Agreement within such ten (10) business day period, neither party shall have any further rights or obligations hereunder except as provided in Sections 3.4, 3.5, 3.6, 9.6

Purchase Price due hereunder equal to the amount of any insurance proceeds or condemnation awards collected by the applicable Seller as a result of any such damage or destruction or condemnation, plus the amount of any insurance deductible, less any
sums expended by such Seller toward the restoration or repair of the affected Property. If the proceeds or awards have not been collected as of the Closing, then such proceeds or awards shall be assigned to Buyer, except to the extent needed to
reimburse the applicable Seller for sums expended prior to the Closing to repair or restore the affected Property.
