Materials (defined above) have been delivered to Buyer and continue for a period of thirty (30)
days thereafter (the “Due Diligence Completion Date”).

connection with this Agreement (collectively, the “Transaction Documents”), the Properties shall be
conveyed to Buyer AS IS, WHERE IS. Except as is otherwise expressly set forth in the Transaction
Documents, it is expressly understood and agreed that Seller is not making, has not made, and

the Properties, and Buyer shall take title to the Fee Properties and Ground Lease Properties in
their present “as-is” condition with all faults, including all latent and patent defects. EXCEPT

Seller (the “Property Contract Notice”) specifying any service agreement with respect to which the
Buyer desires to have Seller terminate before the Close of Escrow (the “Terminated Contracts”)
whereupon such Terminated Contracts shall not be assigned to, or assumed by, Buyer. To the extent
that any such Terminated Contract requires payment of a penalty or premium for cancellation, Seller
shall be solely responsible for the payment of any such cancellation fees or penalties. If Buyer
fails to deliver the Property Contracts Notice on or before the expiration of the Due Diligence
Period, there shall be no Terminated Contracts and Buyer shall assume all Service Agreements at the
Close of Escrow.

7. Title and Survey

(a) Survey. Within three (3) business days of the Effective Date, or as soon as
reasonably possible, Seller shall cause a surveyor reasonably acceptable to Buyer properly licensed
under the laws of the State of Ohio to prepare one or more current and accurate surveys of the
Properties (herein called the “Surveys”) and of the areas to be specifically described by metes and
bounds in the Deeds and Ground Leases required under this Agreement. The Condominium Drawings on
file with the Recorder of Allen County, Ohio, shall be delivered to Buyer’s Attorney in place of a
survey for those Units which are a part of a property which has been submitted to the provisions of
the Ohio Condominium Law in Chapter 5311 Ohio Revised Code. Seller shall cause such Surveys to be
delivered to Buyer’s attorney at the address for copies of notices set forth below for Buyer’s
review and approval. The approved Surveys shall be utilized as the basis for the preparation of
the final legal description of the Fee Properties and Ground Lease Properties to be attached as
Exhibit A and Exhibit B, respectively, and included in the Deeds and Ground Leases to be entered
into by Seller and Buyer at Closing and to be used as the basis in preparation of the applicable
exhibits to the Closing Documents.

(b) Title. Seller shall provide to Buyer’s attorney, within three (3) business days
of the Effective Date, or as soon as reasonably possible, title insurance commitments (the “Title
Commitments”) pursuant to which LandAmerica Title Company (the “Title Company”) agrees to issue to
Buyer at Closing (i) a standard form of Extended Coverage ALTA owners title insurance policy as to
the Fee Properties in the total amount of the Purchase Price, and (ii) a standard form of Extended
Coverage ALTA leasehold title insurance policy for the Ground Lease Properties and the Buyer’s
leasehold interest under the Ground Leases in the total amount of the Purchase Price. Buyer shall
have until the later of (i) the Due Diligence Completion Date or (ii) five (5) business days after
receipt of the Surveys and the Title Insurance Commitments, in which to examine title to the
Properties, review the Title Commitments, and give Seller written notice of any objections to any
matters of record as of the date of the Title Commitments, matters shown on the Title Commitments
and matters shown on the Surveys (“Title Defects”). Any such matters not objected to by Buyer or
waived by Buyer in accordance with this paragraph 7(b) shall be collectively referred to as the
“Permitted Exceptions” in this Agreement. Buyer may reexamine title to the Properties up to and
including the Closing Date and may give Seller written notice of any additional title objections
(which shall be any changes in title which were not requested by Buyer or approved by Buyer)
appearing of record after the effective date of the Title Commitments. Buyer’s failure to specify
in its initial notice of title objections any objection appearing of record or in Buyer’s original
Title Commitments shall be deemed to be, and shall constitute, a waiver of any such objection, and
such objection shall thereafter constitute a Permitted Exception under this Agreement.

(c) Objections. Seller shall have until 5:00 p.m. on the date which is five (5)
business days after receipt of Buyer’s notice of Title Defects to notify Buyer whether it will
attempt to cure the Title Defects, if any. Seller shall have fifteen (15) days after the end of
the Due Diligence Period to cure the Title Defects. If Seller notifies Buyer that it will not
attempt to cure the Title Defects, Buyer shall either (i) terminate this Agreement by providing
Seller with written notice of termination by 5:00 p.m. on the date which is five (5) business days
after receipt of Seller’s notice, in which event the Earnest Money shall be refunded to Buyer, all
rights and obligations of the parties under this Agreement shall expire, all Due Diligence
Materials and other information shall be returned to Seller in accordance with paragraph 17(b), and
this Agreement shall become null and void, or (ii) waive the Title Defects and proceed to Closing,
subject to Buyer’s right to satisfy Permitted Exceptions constituting a liquidated sum of money as
set forth below. If Buyer waives its objections to the Title Defects or Buyer’s objections are
deemed waived, the parties shall proceed to Closing and consummate the purchase and sale of the
Properties, in which event all unsatisfied objections shall constitute Permitted Exceptions under
this Agreement; provided, however, that with respect to any Permitted Exception which constitutes a
liquidated sum of money, Buyer may make payment of such amount to satisfy such Permitted Exception
and deduct the amounts so paid from the Purchase Price due hereunder.

(d) Access. Buyer (and at the direction of Buyer, Buyer’s agents, employees,
contractors, representatives and other designees (hereinafter collectively called “Buyer’s
Designees”)) shall have until the Closing Date to enter the Properties at any reasonable time for
the purposes of performing the Surveys and performing and updating any of the Investigations;
provided, however, that (i) any activities by or on behalf of Buyer, including, without limitation,
the entry by Buyer or Buyer’s Designees onto the Properties, or the other activities of Buyer or
Buyer’s Designees with respect to the Properties (hereinafter called “Buyer’s Activities”) shall
not damage the Properties in any manner whatsoever or disturb or interfere with the rights or
possession of any tenant of the Properties or violate any law or regulation of the municipality in
which each of the Properties is located (the “City”), the State of Ohio or other governmental
agency, (ii) in the event any Property is altered or disturbed in any manner in connection with any
Buyer’s Activities, Buyer shall immediately return such Property to the condition existing prior to
Buyer’s Activities, and (iii) Buyer shall indemnify, defend and hold Seller harmless from and
against any and all claims, liabilities, damages, losses, costs and expenses of any kind or nature
whatsoever (including, without limitation, attorneys’ fees and expenses and court costs) suffered,
incurred or sustained by Seller as a result of, by reason of, or in connection with any Buyer’s
Activities, but excluding any liability resulting from the mere discovery of any pre-existing
conditions. Other than in connection with performing Investigations in accordance with Section 6,
Buyer shall not have the right to undertake any invasive testing, environmental studies or testing
beyond the scope of a standard “Phase I” environmental evaluation without the prior written consent
of Seller.

(e) Insurance. Prior to Buyer or Buyer’s Designees entering the Properties and/or
performing the Investigations, Buyer shall furnish to Seller a certificate from an insurance
company currently (at that time) licensed to do business in the State of Ohio certifying that Buyer
has a valid and existing general liability insurance policy in an amount not less than
$1,000,000.00 issued by an insurance company licensed to do business in the State of Ohio and
reasonably acceptable to Seller naming Seller as an additional insured.

(f) Objectionable Conditions. If Buyer or Buyer’s Designees perform any
Investigations prior to the Due Diligence Completion Date or update any of the Investigations after
the Due Diligence Completion Date and such update reveals that an Objectionable Condition exists,
Buyer shall notify Seller of the Objectionable Condition prior to the later to occur of (i) the Due
Diligence Completion Date, or (ii) three (3) business days after its discovery by Buyer. If Buyer
fails to so notify Seller, Buyer shall be deemed to have waived any Objectionable Condition.

If such Objectionable Condition, (i) was not caused by Buyer or Buyer’s Designees or caused by
Seller or Seller’s designees at the request of Buyer or with Buyer’s approval, and (ii) the cost to
remedy the Objectionable Condition (in aggregate with all other Objectionable Conditions of which
Seller has received proper notice) is greater than $150,000, it shall be deemed a “Major
Objectionable Condition.” If notified of a Major Objectionable Condition, Seller shall give Buyer
a credit at Closing for Seller’s portion of the cost to cure the Major Objectionable Condition
(which shall be amounts over $150,000) (“Seller’s Cost Regarding Major Objectionable Condition”);
provided, however if the aggregate cost to cure all Major Objectionable Conditions is greater than
$300,000, Buyer may elect to terminate this Agreement. Seller shall not be responsible for the
cost to remedy Objectionable Conditions less than $150,000, and, solely with respect to
Objectionable Conditions that arise or are discovered after the Due Diligence Completion Date,
Buyer shall not be entitled to terminate this Agreement and must proceed to Closing if it is not a
Major Objectionable Condition or Seller agrees to provide Buyer a credit at Closing for Seller’s
Cost Regarding Major Objectionable Condition.

If the aggregate cost to cure the Major Objectionable Conditions is greater than $300,000,
Seller shall notify Buyer within five (5) days of Buyer’s notification whether it will attempt to
cure the Major Objectionable Conditions. If Seller elects not to cure, Buyer may either (i) accept
such Major Objectionable Conditions, proceed to Closing and receive a credit of $300,000 in

adjustments shall be made between Buyer and Seller at Closing, or thereafter if Buyer and Seller
shall agree:

(a) At Closing, Escrow Holder shall prorate real estate taxes and general assessments which
are a lien but not yet due and payable based on the most recent tax duplicate (except that if there
is or has been any reduction or abatement of taxes by virtue of the nature of the use of the
Property or by virtue of any exception or reduction in favor of Seller, which reduction or
abatement will no longer apply to the Property if Buyer acquires same or changes the use of the
Property, then the proration shall be based on the full amount of such taxes without reduction or
abatement and Seller shall also be charged with any “recaptured” taxes.) All special assessments
will be paid in full at Closing. When the actual amount of such taxes becomes known, the Escrow
Holder shall adjust the actual tax proration. The Escrow Holder shall retain in escrow an amount
equal to the current tax rate times the difference between [thirty-five percent (35%)] of the
Purchase Price and the assessed tax value of the Property, as shown on the last available County
Treasurer’s tax duplicate pending such adjustment to the tax proration. All assessments,
reassessed assessments and/or respread taxes upon the Property shall be paid in full out of
Seller’s funds at Closing. The balance of any funds held in escrow on account of the tax proration
made pursuant to this paragraph, after the payment of the tax installment for which the taxes were
escrowed, shall be returned to Seller.

(b) All utility charges for the Properties (including, without limitation, telephone, water,
storm and sanitary sewer, electricity, gas, garbage and waste removal) shall be prorated as of the
Closing Date, transfer fees required with respect to any such utility shall be paid by or charged
to Buyer, and Seller shall be credited with any deposits transferred to the account of Buyer;
provided, however, that at either party’s election any one or more of such utility accounts shall
be closed as of the Closing Date, in which event Seller shall be liable and responsible for all
charges for service through the Closing Date and shall be entitled to all deposits theretofore made
by Seller with respect to such utility, and Buyer shall be responsible for reopening and
reinstituting such service in Buyer’s name, and shall be responsible for any fees, charges and
deposits required in connection with such new account. If current, accurate information for
prorating such utility charges is not available on the date of Closing, utility prorations made at
Closing shall be estimated based on the best available information. After Closing and at such time
that accurate information is available, Seller shall re-prorate the utility charges and shall
notify Buyer in writing of the new proration. If the new utility proration reveals that monies are
due either to or from one of the parties, the party owing the money shall pay such money to the
other party within five (5) days of the date of Seller’s notice of the accurate utility proration.

(c) All rents (including base rent, percentage rent and all other rentals), payments for
taxes, payments for insurance, payments for common area maintenance charges, payments for operating
expenses and other payments on account of financial obligations of tenants under the Existing
Leases and the New Leases (herein called the “Tenant Financial Obligations”), which have actually
been paid as of the Closing Date shall be prorated as of the Closing Date. In the event that, at
the time of Closing, there are any past due or delinquent Tenant Financial Obligations, Buyer shall
use its reasonable efforts to collect such past due of delinquent Tenant Financial Obligations.
Seller shall also have the right to make such additional collection efforts as Seller shall deem
appropriate (but may not evict any tenant, cause any tenant to become insolvent, seek protection
under, or be forced into, a bankruptcy or insolvency or otherwise seek to terminate any Leases.
After Closing, (a) all monies received by Seller from or on behalf of any tenant owing delinquent
Tenant Financial Obligations as a result of Seller’s collection efforts shall be delivered to Buyer
for application in accordance with this Section 9(c); and (b) all monies received by Buyer from or
on behalf of any tenant owing delinquent Tenant Financial Obligations as a result of Buyer’s
collection efforts or from Seller pursuant to subsection (a) above shall be applied and paid in the
following order of priority: first, to Seller for delinquent or due but unpaid Tenant Financial
Obligations applicable to periods prior to the Closing Date.; and second, to Buyer for Tenant
Financial Obligations owing to Buyer for periods from and after the Closing Date. In the event
that any Tenant Financial Obligations paid by tenants under the Existing Leases and the New Leases
shall be based upon estimates of actual amounts due and are subject to subsequent adjustment with
the tenant, Seller and Buyer shall make between themselves any equitable adjustment required by
reason of any such subsequent adjustment with the tenant at the time of such subsequent adjustment.
In the event that any Tenant Financial Obligations payable by tenants under the Existing Leases or
New Leases shall be payable after Closing for periods prior to Closing, Seller and Buyer shall make
between themselves any equitable adjustment required by reason of such payments at the time of
actual payment. Further, in the event that, subsequent to Closing, Seller receives any payments of
Tenant Financial Obligations due from tenants under Existing Leases or New Leases for periods after
Closing, Seller shall properly endorse such payments to Buyer, and shall promptly forward such
payments to Buyer.

(d) Buyer shall receive a credit against the Purchase Price in the amount of all, if any,
refundable security deposits and other refundable deposits held by Seller which, as of the Closing
Date, have not been applied or expended for their intended purposes, and Seller shall retain such
funds free and clear of any and all claims on the part of tenants. Buyer shall be responsible for
maintaining as security deposits and other deposits the aggregate amount so credited to Buyer in
accordance with the provisions of the Existing Leases and the New Leases relevant thereto. In the
event that any security deposits are in the form of letters of credit or other financial
instruments (the “Non-Cash Security Deposits”), Seller will, at Closing cause Buyer to be named as
beneficiary under the Non-Cash Security Deposits. Buyer will not receive a credit against the
Purchase Price for such security deposits. In the event that the Buyer cannot be named the
beneficiary under the Non-Cash Security Deposits as of the Closing, an escrow shall be established
at Closing in an amount equal to all Non-Cash Security Deposits under which Buyer is not the
beneficiary as of the Closing.

(e) All amounts payable under any of the Service Agreements being assumed by Buyer shall be
prorated as of the Closing Date.

(f) Any other items which are customarily prorated in connection with the purchase and sale of
real estate in the State of Ohio similar to the Properties shall be prorated as of the Closing
Date.

Except as otherwise provided in Section 9(a), in the event that the amount of any item to be
prorated is not determinable at the time of Closing, such proration shall be made on the basis of
the best available information, and the parties shall re-prorate such item promptly upon receipt of
the applicable bills therefor and shall make between themselves any equitable adjustment required
by reason of any difference between the estimated amount used as a basis for the proration at
Closing and the actual amount subject to proration. The fact that an item has not been prorated
shall be noted on the Closing Statement and information with regard to the availability of the
information and how the re-proration is to be made will be described on the Closing Statement. The
re-proration shall be completed on or before sixty (60) days after Closing, unless the information
necessary for the re-proration is not available at that time. In the event any prorated item is
due and payable at the time of Closing, the same shall be paid at Closing. If any prorated item is
not paid at Closing, Seller shall deliver to Buyer the bills therefor promptly upon receipt thereof
and Buyer shall be responsible for the payment in full thereof within the time fixed for payment
thereof and before the same shall become delinquent. In making the prorations required by this
paragraph 6, the economic burdens and benefits of ownership of the Properties for the Closing Date
shall be allocated to Buyer.

any one or more of the conditions set forth in this paragraph, and there is no default by Seller or
default by Buyer hereunder, then the Earnest Money shall be returned to Buyer, and thereafter no
party hereto shall have any rights, claims, obligations or liabilities hereunder, except for those
that are expressly provided herein to survive a termination of this Agreement.

13. Remedies(a) If the purchase and sale of the Properties contemplated hereby is not
consummated in accordance with the terms and provisions of this Agreement due to circumstances or
conditions which constitute a default by Buyer under this Agreement, Seller shall be entitled to
terminate this Agreement and recover the Earnest Money as liquidated damages for such default, and
not as a penalty or forfeiture, in satisfaction of claims against Buyer hereunder, and Seller
agrees that this shall be Seller’s sole and exclusive remedy for any such default by Buyer. Seller
and Buyer agree that it would be impracticable and extremely difficult to fix the actual damages
suffered by Seller as a result of Buyer’s failure to complete the purchase of the Properties
pursuant to this Agreement. The parties further agree that under the circumstances existing as of
the date hereof, the Earnest Money as liquidated damages represents a reasonable estimate of the
damages which Seller would incur as a result of such failure.

(b) If the purchase and sale of the Properties contemplated hereby is not consummated in
accordance with the terms and provisions of this Agreement due to circumstances or conditions which
constitute a default by Seller under this Agreement, Buyer may elect one of the following remedies:
(i) specific performance of Seller’s obligations hereunder, it being acknowledged that the
Properties are unique and that monetary damages would not be an adequate remedy; or (ii) to
terminate this Agreement by giving Seller written notice of such election prior to or at Closing
and recover the Earnest Money, and Seller shall, promptly following Buyer’s demand tendered in
reasonable detail, accompanied by appropriate and reasonable backup documentation to Seller within
thirty (30) days after the termination, reimburse Buyer for all of Buyer’s out-of-pocket costs and
expenses (including, without limitation, the costs of title, survey, reports, studies, third-party
consultants, lender charges and commitment fees, travel expenses, and reasonable attorney’s fees)
incurred in this transaction (provided, however, in no event shall Seller reimburse Buyer for costs
and expenses in excess of $50,000), and thereafter all rights and obligations of the parties under
this Agreement shall expire and this Agreement shall become null and void. The inability of Seller
to convey good and marketable fee simple title to the Properties on the Closing Date shall not
constitute a default by Seller under this Agreement unless such inability is caused by a defect in
Seller’s title to the Properties which is not a Permitted Exception under this Agreement, which
arises subsequent to the date of Seller’s execution of this Agreement, and which arises solely by
reason of an affirmative act of Seller. Except as otherwise expressly set forth in this Agreement,
Seller shall have no other liability to Buyer under this Agreement.

14. Damage or Destruction(a) If any portion of any of the Properties is damaged or
destroyed by casualty prior to Closing, Seller shall give Buyer prompt written notice thereof. If
damage or destruction by casualty in an amount which exceeds $200,000 to repair occurs at any one
of the Properties or damage or destruction by casualty in an amount exceeding $1,000,000 in the
aggregate at any or all of the Properties occurs prior to Closing, Buyer shall have the right, at
Buyer’s option, to terminate this Agreement by giving written notice to Seller on or before the
date ten (10) days after the date upon which Seller gives Buyer written notice of such casualty, in
which event the Earnest Money shall be refunded to Buyer promptly upon request, all rights and
obligations of the parties under this Agreement shall expire, and this Agreement shall become null
and void. In the event of lesser damage or destruction, Buyer shall have no right to terminate
this Agreement by reason of such damage or destruction.

(b) If any portion of the Properties is damaged or destroyed by casualty prior to Closing and
the purchase and sale of the Properties contemplated by this Agreement is thereafter actually
consummated, the Purchase Price shall be reduced by the estimate of the cost of reconstruction as
reasonably determined by Buyer and Seller.

15. Representations and Warranties(a) Mutual Representations. To induce each
other to enter into this Agreement, each party hereby represents and warrants to the other that (i)
it has been duly authorized and empowered to enter into this Agreement and to perform fully its
obligations hereunder, (ii) such obligations constitute the valid and binding obligations of such
party, enforceable in accordance with their terms, and (iii) that no further consents of any other
person, entity, public body or court are required in connection with this Agreement and the
performance of all obligations hereunder.

(b) Seller’s Warranties and Representations. To induce Buyer to enter into this
Agreement, Seller represents and warrants to Buyer, except as referenced in the Exhibits attached
hereto and incorporated herein by this reference that:

(i) Marketable Title. Seller has good and marketable title to the Properties, subject
to the Permitted Exceptions. There are no outstanding rights of first refusal, rights of reverter
or options relating to the Properties or any interest therein. To Seller’s knowledge, there are no
unrecorded or undisclosed documents or other matters which affect title to the Properties, except
Tenant Leases. Subject to the Leases, Seller has enjoyed the continuous and uninterrupted quiet
possession, use and operation of the Properties, without material complaint or objection by any
person;

(ii) Utilities. To Seller’s knowledge, all water, sewer, gas, electric, telephone and
drainage facilities, and all other utilities required by law or by the normal operation of the
Properties are connected to the Properties and are adequate to service the Properties in its
present use and normal usage by the tenants and occupants of the Properties and are in good working
order and repair;

(iii) Material Defects. Seller has no knowledge of or experienced any physical or
mechanical defects in the buildings or any material settlement or earth movement affecting the
Properties;

(iv) Claims and Settlements. There are no unpaid bills, claims, or liens in
connection with any construction or repair of the Properties except for those that will be paid in
the ordinary course of business prior to Closing or which have been bonded over or the payment of
which has otherwise been adequately provided for to the satisfaction of Buyer;

(v) Personal Property. Seller has good title to all the Personalty and the execution
and delivery to Buyer of the Bill of Sale shall vest good title to all of the Personalty in Buyer,
free and clear of liens, encumbrances and adverse claims;

(vi) Rights. Neither Seller nor any previous owner of the Properties has, except by operation
of law, sold, transferred, conveyed, or entered into any agreement regarding “air rights,” “excess
floor area ratio,” or other rights or restrictions relating to the Properties except as otherwise
expressly set forth in the Title Policy for the Properties;

(vii) Zoning. Seller has no knowledge of any pending application for changes in the
zoning affecting Properties, and Seller has received no written notification that any governmental
authority has determined that there are any zoning violations with respect to the Properties.

(viii) Licenses/Permits. Seller possesses all governmental licenses and permits which
may be necessary to the operation of the Properties and all such licenses and permits are current
and valid. To Seller’s knowledge, neither the Properties nor the use thereof violates any
governmental law or regulation or any covenants or restrictions encumbering the Properties and
there are no material physical defects in the Improvements. Seller has not received any written
notice from any insurance company or underwriter, nor is it aware, of any defects that would
materially adversely affect the insurability of the Properties or cause an increase in insurance
premiums. Seller has not received written notice from any governmental authority or other person
of, and has no knowledge of any violation of zoning, building, fire, health, environmental, or
other statutes, ordinances, regulations or orders (including those respecting the Americans with
Disabilities Act), or any restriction, condition, covenant or consent in regard to the Properties
or any part thereof which have not been corrected to the satisfaction of the issuer.

(ix) Environmental Condition. To the best of Seller’s knowledge and belief, the
Properties are free of “contamination” from (A) any “hazardous waste,” any “hazardous substance,”
and any “oil, petroleum products, and their by-products,” as such terms are defined by any federal,
state, county or local law, ordinance, regulation or requirement applicable to any Property, as the
same may be amended from time to time, and including any regulations promulgated thereunder, and
(B) any substance the presence of which on the Properties are regulated or prohibited by any law
(collectively, “Hazardous Substances”). “Contamination” means the presence of Hazardous Substances
at a Property or arising from a Property that may require remediation or cleanup under any
applicable law. Seller has not used any Hazardous Substances on, from or affecting a Property in
any manner that violates any applicable law, and to the best of Seller’s knowledge, no prior owner
or user or tenant of the Properties has used such substances on, from, or affecting the Properties
in any manner which violates any applicable law. Other than the remediation and removal actions
described on Appendix 5 and any biohazardous waste generated by space tenants in the regular course
of business (all tenants are responsible for the removal of such biohazardous waste from the leased
premises as set forth in such tenant leases), Seller has no knowledge of any need for mold
remediation or asbestos removal at the Properties. Seller shall notify Buyer of any governmental
notice or a notice from any other entity with regard to the violation of any applicable laws with
regard to the Properties.

(x) Litigation. There is no litigation, arbitration or proceeding pending or, to the
best of Seller’s knowledge and belief, threatened, before any court or administrative agency or any
other condition that relates to or affects the Properties, Seller’s performance hereunder, or
Buyer’s intended use of the Properties, or which will result in a lien, charge, encumbrance or
judgment against any part of or any interest in the Properties.

(xi) No Contracts. Seller has not entered into any other contracts, agreements or
understandings, written or, to the best of Seller’s knowledge and belief, verbal, for the sale or
transfer of any portion of the Properties which are currently in force. Between the date of this
Agreement and all closing hereunder, no part of the Properties will be alienated, encumbered or
transferred except as contemplated by this Agreement.

(xii) Non-Foreign Certification. Seller is not a “foreign person” which would subject
Buyer to withholding tax provisions of Section 1445 of the Internal Revenue Code of 1986, as
amended.

(xiii) Condemnation. There are no pending condemnation actions with respect to the
Properties, nor, to the best of Seller’s knowledge and belief, has Seller received any notice of
contemplated or threatened condemnation.

(xiv) Leases. Except for the leases described on Exhibit C attached hereto, Seller
has not entered into any leases, tenancies, licenses, occupancies, concessionaires or occupancy
agreements with respect to the Properties or any portion thereof which remain in effect and no
person or entity other than Seller is in possession or has any right of possession to all or any
portion of the Properties. Attached hereto as a portion of Exhibit C is a true, correct and
complete copy (as of the date of this Agreement) of the rent rolls for the Properties which rent
rolls will be updated at Closing and provided to Buyer. As to any leases, tenancies, licenses,
occupancies, concessionaires or occupancy agreements being assigned by Seller to Buyer, Seller has
paid or will pay prior to Closing all leasing commissions, tenant improvement costs and other costs
and expenses associated with such leases, tenancies, licenses, occupancies, concessionaires or
occupancy agreements. To the best of Seller’s knowledge and belief, no defaults exist under any
Existing Lease other than as disclosed in Exhibit C.

(xv) Service Agreements. Except as listed on Exhibit D, there are no management,
service or other contracts or agreements which affect the Properties. To the best of Seller’s
knowledge and belief, no default exists under any Service Agreements other than as disclosed on
Exhibit L.

(xvi) Property Information. To the best of Seller’s knowledge and belief, copies of
the Due Diligence Materials and all documents containing information material to the ownership or
operation of the Properties have been delivered to Buyer and are true, correct and complete copies;
and Seller is not aware of any material inaccuracy or omission in such information.

(xvii) ERISA.

(a) that Seller is not and is not acting on behalf of (i) an “employee benefit plan” within
the meaning of Section 3(3) of the Employee Retirement Income Security Act of 1974, as amended
(“ERISA”), (ii) a “plan” within the meaning of Section 4975 of the Internal Revenue Code of 1986,
as amended or (iii) an entity deemed to hold “plan assets” within the meaning of 29 C.F.R.
§2510.3-101 of any such employee benefit plan or plans; and

(b) that either (i) Seller is not a “party in interest”, within the meaning of Section 3(14)
of ERISA with respect to any “employee benefit plan” within the meaning of Section 3(3) of ERISA or
(ii) neither Seller nor its affiliates (within the meaning of part V(c) of Department of Labor
Prohibited Transaction Class Exemption 84-14 (“PTE 84-14”), during the immediately preceding year,
has had the authority to appoint or terminate Buyer as an investment manager to any employee
benefit plan, or negotiate the terms of any management agreement between Buyer and any employee
benefit plan; and

(c) that Seller is not “related” to Buyer within the meaning of part V(h) of PTE 84-14.

(xviii) Patriot Act. Seller is not acting, directly or indirectly for, or on behalf
of, any person, group, entity or nation named by any Executive Order (including the September 24,
2001, Executive Order Blocking Property and Prohibiting Transactions With Persons Who Commit,
Threaten to Commit, or Support Terrorism) or the United States Treasury Department as a terrorist,
“Specially Designated National and Blocked Person,” or other banned or blocked person, entity, or
nation pursuant to any Law that is enforced or administered by the Office of Foreign Assets
Control, and is not engaging in the transactions described herein, directly or indirectly, on
behalf of, or instigating or facilitating the transactions described herein, directly or
indirectly, on behalf of, any such person, group, entity or nation.

(c) Survival. The representations and warranties of the parties set forth herein
shall be true as of the effective date and the date of closing and shall survive the closing for a
period of one (1) year. Seller shall notify Buyer in writing immediately if any representation
becomes untrue or misleading in light of information obtained by Seller after the effective date.

16. Condemnation(a) In the event of commencement of eminent domain proceedings
respecting any portion of the Properties prior to Closing, Seller shall give Buyer prompt written
notice thereof. If all or any part of the Properties is taken by eminent domain proceedings, or if
there is the commencement or bona fide threat of the commencement of any such proceedings prior to
Closing, Buyer shall have the right, at Buyer’s option, to terminate this Agreement by giving
written notice to Seller on or before the date ten (10) days after the date upon which Seller gives
Buyer written notice of such taking, in which event the Earnest Money shall be refunded to Buyer
promptly upon request, all rights and obligations of the parties under this Agreement shall expire,
and this Agreement shall become null and void.

(b) If all or any part of the Properties is taken by eminent domain proceedings prior to
Closing and the purchase and sale of the Properties contemplated by this Agreement is thereafter
actually consummated: (1) the Purchase Price shall be reduced by the total of any awards or other
proceeds actually received by Seller on or before the Closing Date with respect to any taking and
not expended by Seller prior to Closing for the repair or restoration of the Properties; and (ii)
at Closing, Seller shall assign to Buyer all rights of Seller in and to any awards or other
proceeds payable thereafter by reason of such taking.

17. Ownership of Information; Confidentiality Obligation(a) Reserved.

(b) If the purchase and sale of the Properties is not consummated in accordance with this
Agreement, regardless of the reason or the party at fault, Buyer shall immediately deliver to
Seller, at Buyer’s cost and expense and at no cost or expense to Seller: (i) a list setting forth
the names of all persons or entities who conducted investigations, examinations, tests or
inspections of or with respect to the Properties on behalf of or at the instance of Buyer; (ii)
using Buyer’s commercially reasonable efforts, substantially all reports, studies, surveys, site
plans and other written or graphic material of any kind or nature whatsoever generated, collected,
prepared or compiled by third parties in connection with such investigations, examinations, tests
or inspections; and (iii) an instrument in form and substance reasonably satisfactory to Seller
transferring and assigning to Seller all of Buyer’s rights, title and interest in or to the
materials described in clause (ii), above. Buyer’s obligation to deliver to Seller all items
required by this subparagraph (b) shall survive any termination of this Agreement, but Buyer shall
be entitled to a distribution of the Earnest Money, so long as it would otherwise be entitled to
such Earnest Money under the terms of this Agreement, prior to the delivery by Buyer to Seller of
the documents described in this paragraph 17(b).

(c) No information or contents of any environmental reports, nor the results of any
investigation of the Properties, including, but not limited to, the contents of the report issued
in connection therewith, shall be disclosed by Buyer or its agents, consultants or employees to any
third party without Seller’s prior written approval, unless and until Buyer is legally compelled to
make such disclosure under applicable laws or until Buyer consummates its purchase of the
Properties pursuant to this Agreement. Notwithstanding the foregoing, Buyer may disclose such
matters to Buyer’s consultants and Buyer’s directors, officers, employees, legal counsel, lenders,
lender’s counsel, investors and investors’ counsel (other than Disqualified Person(s)) or
prospective lenders (herein collectively called the “Related Parties”) who, in Buyer’s reasonable
opinion, must know such information for the purpose of evaluating the same for Buyer as a potential
purchaser of the Properties.

For purposes of this Agreement, “Disqualified Person(s)” shall mean any person, entity, or any
affiliate of a person or entity, which directly or indirectly engages in activities that are
Prohibited Competitive Services or are directly competitive with Seller in the following counties:
The Ohio counties of Allen, Auglaize, Hardin, Logan, Mercer, Putnam and Van Wert (and all
incorporated cities, towns and municipalities located within such counties); provided, however,
that (i) no lender or prospective lender of Buyer shall be considered a Disqualified Person and
(ii) no person shall be considered a Disqualified Person on account of the fact that an affiliate
of such person that is an upper tier investor in such person (that is, an entity which does not own
direct ownership interests in such person) directly or indirectly engages in activities that are
directly competitive with Seller if such affiliate is a “sister” affiliate and is controlled either
by an institutional investor or a person whose ownership interests are publicly traded.

“Prohibited Competitive Services” are those services described on Exhibit E attached hereto
and incorporated herein by this reference. Activities and/or opportunities relating to the
development ownership operation and/or management of hospitals, acute care facilities, outpatient
clinics or ambulatory centers will be considered “directly competitive” with Seller’s business. A
Disqualified Person shall specifically inc1ude, but not be limited to, any entity owned by, related
to or affiliated with Lima Memorial Health System or it’s successors. Buyer shall take all
necessary actions to ensure that any Related Parties to whom such documents items or information
are furnished not make the same available or disclose the contents thereof to any person. If this
Agreement is terminated for any reason, Buyer shall immediately return to Seller substantially all
(using Buyer’s best efforts) documents plans and other items furnished to Buyer or any Related
Parties pursuant to this subparagraph (c) without retaining copies thereof. Notwithstanding
anything herein to the contrary the provisions of this subparagraph (c) shall survive the
consummation of the purchase and sale of the Properties on the Closing Date hereunder or any
termination or cancellation of this Agreement.

18. Broker and CommissionAll negotiations relative to this Agreement and the purchase
and sale of the Properties as contemplated by and provided for in this Agreement have been
conducted by and between Seller and Buyer without the intervention of any person or other party as
agent or broker, with the exception of Shattuck Hammond Partners (“Broker”) which represents
Seller. Seller shall pay any commission owed to Broker in connection with the sale of the
Properties and Seller agrees to indemnify Buyer from and against any and all claims, demands or the
costs and expense thereof including reasonable attorney’s fees arising out of any claim by Broker
for a brokerage commission, fee or other compensation due or alleged to be due in connection with
the transaction contemplated by this Agreement. In addition each party agrees to indemnify and
hold the other harmless from and against any and all other claims demands or the costs and expense
thereof including reasonable attorney’s fees arising out of any brokerage commission fee or other
compensation due or alleged to be due in connection with the transaction contemplated by this
Agreement based on an agreement alleged to have been made or other action alleged to have been
taken by the indemnifying party.

19. SurvivalThe provisions of paragraphs 8, 15, 17 and 21(d) of this Agreement and the
provisions of paragraph 7(d) of this Agreement shall survive the consummation of the purchase and
sale of the Properties on the Closing Date, the delivery of the Deed and the payment of the
Purchase Price provided that any claims under Section 15 shall be subject to the time limitation
set forth in Section 15(c). Notwithstanding anything to the contrary set forth in this Agreement,
the provisions of paragraphs 12, 17, and 18 of this Agreement and the provisions of paragraph 5(c)
of this Agreement shall also survive any termination of this Agreement in accordance with its terms
for twelve (12) months from the Closing Date.

terminate or extend any of the Existing Leases or enter any New Leases, Seller shall deliver
written notice to Buyer of such intention, which written notice shall contain information regarding
the proposed action that Seller believes is reasonably necessary to enable Buyer to make an
informed decision with respect to the proposed action. If Buyer has not responded within five (5)
business days of the date of a written request by Seller, Buyer’s consent shall be deemed given.
Any notice from Buyer rejecting the proposed action shall include a description of the reasons for
Buyer’s objection specified in reasonable detail. All leasing commissions, tenant improvement
costs or other costs and expenses incurred by Seller with respect to the foregoing shall be at
Seller’s costs and expense.

conditioned or delayed, Seller shall not modify, amend, terminate or waive any provisions of any

required to make certain filings with the Securities and Exchange Commission (the “SEC Filings”)

The provisions of this Section 21(d) shall survive the Closing.

(e) Headings. The use of headings, captions and numbers in this Agreement is solely
for the convenience of identifying and indexing the various provisions in this Agreement and shall
in no event be considered otherwise in construing or interpreting any provision in this Agreement.

(f) Exhibits. Each and every exhibit referred to or otherwise mentioned in this
Agreement is attached to this Agreement and is and shall be construed to be made a part of this
Agreement by such reference or other mention at each point at which such reference or other mention
occurs, in the same manner and with the same effect as if each exhibit were set forth in full and
at length every time it is referred to or otherwise mentioned.

(g) Defined Terms. Capitalized terms used in this Agreement shall have the meanings
ascribed to them at the point where first defined, irrespective of where their use occurs, with the
same effect as if the definitions of such terms were set forth in full and at length every time
such terms are used.

(h) Pronouns. Wherever appropriate in this Agreement, personal pronouns shall be
deemed to include the other genders and the singular to include the plural.

(i) Severability. Wherever possible, each provision of this Agreement shall be
interpreted in such manner as to be effective and valid under applicable law, but if any term or
other provision of this Agreement (or the application of any term or provision of this Agreement to
any person or circumstance) shall be held by a court of competent jurisdiction to be invalid,
inapplicable, illegal or incapable of being enforced by any rule of law or public policy, all other
conditions and provisions of this Agreement (or the application of such term or provision to
persons or circumstances other than those as to which it is held invalid or unenforceable) shall
nevertheless remain in full force and effect so long as the economic or legal substance of the
transactions contemplated hereby is not affected in any manner adverse to any party. Upon
determination that any term or other provision is invalid, inapplicable, illegal or incapable of
being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to
effect the original intent of the parties as closely as possible in an acceptable manner to the end
that transactions contemplated hereby are fulfilled to the maximum extent possible.

(j) Knowledge. Wherever in this Agreement reference is made to Seller’s Knowledge or
Knowledge of Seller, it shall be deemed to mean the actual knowledge of the officers of Seller
after reasonable inquiry of Seller’s management employees, officers, property management and
Seller’s agents and representatives.

(k) Non-Waiver. Failure by any party to complain of any action, nonaction or breach
of any other party shall not constitute a waiver of any aggrieved party’s rights hereunder. Waiver
by any party of any right arising from any breach of any other party shall not constitute a waiver
of any other right arising from a subsequent breach of the same obligation or for any other
default, past, present or future.

(l) Time of Essence; Dates. Time is of the essence of this Agreement. Anywhere a day
