Inspection. Purchaser may inspect, test, and survey: (a) the Property, (b) all financial records pertaining to the operation of the Property, and (c) photocopies of all Leases and Contracts in the possession or control of Seller, at any reasonable time during business hours at any time during the Approval Period (collectively, the “Purchaser Investigations”). Notwithstanding the foregoing, Purchaser must obtain Seller’s prior written approval of the scope and method of any environmental testing or investigation (other than a non-intrusive Phase I environmental inspection) and any inspection which would materially alter the physical condition of the Property, prior to Purchaser’s commencement of such inspections or testing. In any event, Seller and its representatives, agents, and/or contractors shall have the right to be present during any of the Purchaser Investigations. If the Purchaser Investigations reveal any fact or condition unacceptable to Purchaser, Purchaser shall notify Seller in writing prior to the expiration of the Approval Period of such unacceptable fact or condition and Seller shall have the right (without any obligation to do so) to correct same by the Closing Date. If Seller does not correct such unacceptable fact or condition by the Closing Date, Purchaser may terminate this Agreement in which event the Earnest Money will be returned to Purchaser, and neither party shall have any further right or obligation hereunder other than the Surviving Obligations. If Purchaser does not give such notification to Seller in writing prior to the expiration of the Approval Period, the

Page 4

said investigations of the Property shall be deemed satisfactory to Purchaser and Purchaser shall be deemed to have agreed to assume all obligations from and after the date of Closing with respect to the Leases and the Contracts. All information provided by Seller to Purchaser or obtained by Purchaser relating to the Property in the course of the Purchaser Investigations, including, without limitation, any environmental assessment or audit (collectively, the “Reports”) shall be treated as confidential information by Purchaser and Purchaser shall instruct all of its employees, agents, representatives and contractors as to the confidentiality of all such information. Other than research of any applicable general land use and other laws and/or any public records and databases, and the routine communications with regulatory or governmental agencies and their individual employees associated therewith, neither Purchaser nor any Purchaser Representative (defined in Section 4.2.1(a) of this Agreement) shall communicate with any regulatory or governmental agencies or their individual employees concerning the Property, without the prior written consent of Seller, which shall be given or withheld in Seller’s sole discretion. Neither Purchaser nor any Purchaser Representative shall contact or communicate with any tenant, occupant, or leasing agent of the Property or any governmental agent regarding the Property without prior written notice to Seller, and Seller reserves the right to participate in any such contact; provided, however, that Purchaser may review governmental records and make routine contact with governmental officials in connection with Purchaser’s customary due diligence activities pursuant to this Agreement such as, but not limited to, confirmation of zoning and review of ordinance or statutory compliance without first providing notice. Seller acknowledges that Purchaser, at its sole expense, will be conducting an audit of property-level financials as specified by Rule 3-14 of Regulation S-X of the Securities Act of 1933, as amended, and the Securities Exchange Act of 1934, as amended, and Seller agrees to reasonably cooperate and assist Purchaser in obtaining any and all such data and financial information that shall be reasonably available to Seller (including, without limitation, data and information obtainable from Property Manager), and permit Purchaser’s auditors reasonable access to such information.

(iii) Before and during Purchaser Investigations, Purchaser and Purchaser’s representatives, including Purchaser’s engineers, contractors and environmental consultants (collectively, the “Purchaser Representatives”) conducting any Purchaser Investigation shall maintain workers’ compensation insurance in accordance with applicable law, and Purchaser, and the applicable Purchaser Representative conducting any Purchaser Investigation, shall maintain (1) commercial general liability insurance, on a per occurrence basis, with limits of at least Three Million Dollars ($3,000,000.00) for bodily or personal injury or death, (2) property damage insurance in the amount of at least One Million Dollars ($1,000,000.00), and (3) contractual liability insurance, on a per occurrence basis, with respect to Purchaser’s obligations under this Section 4.2. Purchaser shall deliver to Seller evidence of such workers’ compensation insurance and a certificate evidencing the commercial general liability, property damage and contractual liability insurance before conducting any Purchaser Investigation on the Property. Each such insurance policy shall be written by a reputable insurance company having a rating of at least “A+:VII” by Best’s Rating Guide (or a comparable rating by a successor rating service), and shall otherwise be subject to Seller’s prior approval. Such insurance policies shall name as additional insureds Seller, Property Manager and such other parties holding insurable interests as Seller may designate. Such insurance shall be primary to any insurance maintained by Seller or Property Manager as to claims arising from, related to or in connection with the acts, errors or omissions of Purchaser and/or Purchaser’s Representatives.

Purchaser shall, at its own expense, immediately fill and compact any holes, and otherwise restore any damage to the Property related to the Purchaser Investigations. Upon Purchaser’s completion of Purchaser Investigations, Purchaser shall be responsible for returning the Property to substantially the condition existing prior to Purchaser’s entry. Neither Purchaser nor any Purchaser Representative shall damage any part of the Property or any personal property owned or held by Seller, Property Manager or any tenant or third party.

Purchaser shall indemnify, defend and hold Seller and the other Releasees (as defined in Section 5.3) harmless from any and all losses, costs, liens, claims, causes of action, liability, damages, expenses and liability (including, without limitation, court costs and reasonable attorneys’ fees) incurred in connection with or arising in any way from (1) any Purchaser Investigation conducted by Purchaser and/or any

Page 5

Purchaser Representative, or (2) any breach by Purchaser and/or any Purchaser Representative of the terms of this Section 4.2, even though any such loss is caused or alleged to be caused by the negligence or fault of any Releasees (other than any such loss arising solely as the result of the gross negligence or willful misconduct of Seller or its agents). This indemnity is intended to indemnify the Releasee against the consequences of their own negligence or fault as provided above when any Releasee is solely, jointly, comparatively, contributively, or concurrently negligent with Purchaser and/or any Purchaser Representative. Notwithstanding the foregoing, in no event shall the Purchaser’s indemnity obligations hereunder extend to any claim by Seller arising solely by reason of the mere discovery of any adverse conditions or legal noncompliance on the Property (as opposed to causing or the disturbance or exacerbation of any such adverse conditions or legal noncompliance) by Purchaser or any Purchaser Representative during any Purchaser Investigation. This indemnity provision shall survive termination or expiration of this Agreement for a period commensurate with the expiration of any applicable statute of limitations. If any proceeding is filed for which indemnity is required hereunder, Purchaser agrees, upon request therefor by any of the Releasees, to defend the indemnified party in such proceeding at its sole cost utilizing counsel satisfactory to the indemnified party, in its reasonable discretion.

Purchaser’s Representations and Warranties.

Purchaser’s Funds.

Purchaser has taken, and shall continue to take until Closing, such measures as are required by law to assure that the funds used to pay to Seller the Purchase Price are derived (i) from transactions that do not violate United States law nor, to the extent such funds originate outside the United States, do not violate the laws of the jurisdiction in which they originated; and (ii) from permissible sources under United States law and to the extent such funds originate outside the United States, under the laws of the jurisdiction in which they originated.

To the best of Purchaser’s knowledge after making due inquiry, neither Purchaser nor any Purchaser Party, nor any Person providing funds to Purchaser (i) is under investigation by any governmental authority for, or has been charged with, or convicted of, money laundering, drug trafficking, terrorist related activities, any crimes which in the United States would be predicate crimes to money laundering, or any violation of any Anti Money Laundering Laws; (ii) has been assessed civil or criminal penalties under any Anti-Money Laundering Laws (as defined herein); or (iii) has had any of its funds seized or forfeited in any action under any Anti Money Laundering Laws.

The Purchaser’s representations and warranties set forth in this Section 4.3 shall survive the Closing or termination of this Agreement for a period of one (1) year. Purchaser’s representations and warranties contained herein must be true and correct through the Closing Date, and Purchaser’s failure to notify Seller prior to the Closing Date of any inaccuracies shall be a default by Purchaser under this Agreement.

Page 7

Seller’s Representations and Warranties. Seller represents and warrants to Purchaser that Seller has the full partnership/corporate right, power, and authority, without the joinder of any other person or entity, to enter into, execute and deliver this Agreement, and to perform all duties and obligations imposed on Seller under this Agreement, and neither the execution nor the delivery of this Agreement, nor the consummation of the purchase and sale contemplated hereby, nor the fulfillment of or compliance with the terms and conditions of this Agreement conflict with or will result in the breach of any of the terms, conditions, or provisions of any agreement or instrument to which Seller is a party or by which Seller or any of Seller’s assets is bound.

Know Your Customer. Purchaser acknowledges that Seller must complete certain “know your customer” procedures regarding Purchaser, including, without limitation, understanding the principals and other investors in Purchaser and Purchaser’s source of funds. To this end, Purchaser shall cooperate with Seller in these efforts, including, without limitation, delivering to Seller upon request the full names of all the individuals and business entities involved in the transaction on Purchaser’s behalf, all parties contributing or receiving any money, compensation or ownership interests, and a detailed Purchaser organization chart. All such information shall be treated as confidential information by Seller and Seller’s directors, officers, partners, employees, legal counsel, accountants, engineers, architects, financial advisors and similar professionals and consultants, unless such disclosure is required by law. Seller shall have seven (7) days after receiving information reasonably requested by Seller from Purchaser to notify Purchaser of any objection Seller may have. If such notice is not timely given, then the person or entity in question shall be deemed approved. Any person or entity approved or deemed approved shall not be subject to further approval or deemed approval absent a material adverse change in the facts concerning such person or entity. Subject to the preceding sentence, if Seller, in Seller’s sole and absolute discretion, is not satisfied with the results of such “know your customer” due diligence or if Purchaser fails to deliver to Seller all of the information required by Seller, then Seller shall have the right to terminate this Agreement, which right must be exercised within seven (7) days after receipt of the information reasonably requested from Purchaser by Seller, which right may be exercised only upon prior written notice delivered to Purchaser, in which event the Earnest Money shall be returned to Purchaser and neither party shall have any further obligations hereunder except for the Surviving Obligations.

Tenant Estoppel Certificates. Seller agrees to submit or cause Property Manager to submit within five (5) business days after the Effective Date hereof to each and every tenant or lessee under a Lease a request for such tenant or lessee to execute and deliver to Purchaser a tenant estoppel certificate with respect to its Lease in the form attached hereto as Exhibit G or on the form promulgated by the tenant and reasonably acceptable to Purchaser, or required by the applicable Lease. It shall be a condition precedent to Purchaser’s obligation to purchase the Property that Purchaser receive and reasonably approve tenant estoppel certificates from all tenants or lessees leasing in excess of 5,000 gross square feet (“Major Tenants”) and from a sufficient number of non-Major Tenants so that Purchaser shall have received estoppel certificates from such number of tenants or lessees which collectively occupy at least eighty percent (80%) of the leased square footage of the Property (collectively, the “Required Estoppels”) on the form of the estoppel certificates attached as Exhibit G or on the form promulgated by the tenant and reasonably acceptable to Purchaser, or required by the applicable Lease. Seller shall deliver or cause to be delivered to Purchaser the Required Estoppels within the earlier to occur of (i) two (2) business days of Seller’s receipt of same, or (ii) thirty (30) days after the Effective Date. Purchaser shall have until the expiration of the Approval Period to disapprove of any such Required Estoppel, it being understood that if Purchaser does not disapprove of any Required Estoppel before the expiration of the Approval Period, then Purchaser shall be deemed to have approved such Required Estoppel. Seller shall make a commercially reasonable number of oral and a minimum of one (1) written request for the Required Estoppels, but shall not be obligated to expend any funds in connection with obtaining any of the estoppel certificates, including the Required Estoppels described in this Section 4.6, and the failure of Seller to obtain any such estoppel certificates, including the Required Estoppels shall not be a breach or default hereunder. If Purchaser does not receive and reasonably approve the Required Estoppels on or before the end of the Approval Period, Seller may extend the Approval Period up to fourteen (14) days for the limited purpose of allowing Seller to obtain the Required Estoppels. If Purchaser does not receive and

Page 8

reasonably approve the Required Estoppels on or before the expiration of such fourteen (14) day extension of the Approval Period, if applicable, Purchaser may either (i) terminate this Agreement in writing delivered to Seller on or before the expiration of such extended Approval Period, in which event the Earnest Money shall be returned to Purchaser and neither party shall have any further obligations hereunder other than the Surviving Obligations, or (ii) waive the foregoing condition precedent and proceed to Closing. If Purchaser shall not have terminated this Agreement under this Section 4.6 prior to the expiration of the Approval Period or the extension thereof as provided for herein, Purchaser shall be deemed for all purposes to be satisfied with the responses to Seller’s requests for tenant estoppel certificates, including the Required Estoppels and the form and substance of each tenant estoppel certificate and shall have no further right to terminate this Agreement based on the response or lack thereof with respect to the tenant estoppel certificates, including the Required Estoppels.

Subordination, Non-Disturbance and Attornment Agreements. If requested by Purchaser, Seller agrees to use commercially reasonable efforts to request or cause Property Manager to request a subordination, non-disturbance and attornment agreement from a tenant or tenants as Purchaser’s lender requests, in the form required by Purchaser’s lender if same is required by such lender, provided, however, that receipt of any such subordination, non-disturbance and attornment agreement(s) by Purchaser or its lender shall not be a condition precedent to Purchaser’s obligation to purchaser the Property at the Closing.

(the “Title Company”) at 2626 Howell Street, 10th Floor, Dallas, Texas 75204, Attention: Russell Dickson, at a date designated by Seller and Purchaser on or before fifteen (15) days after the expiration of the Approval Period (the “Closing Date”), unless the parties mutually agree in writing upon another place, time or date.

Possession. Possession of the Property shall be delivered to Purchaser at the Closing.

Proration. All rents, other amounts payable by the tenants under the Leases, income, utilities and all other operating expenses with respect to the Property for the month in which the Closing occurs, and real estate and personal property taxes and other assessments with respect to the Property for the year in which the Closing occurs, shall be prorated to the date Seller receives the Purchase Price in immediately available funds with Seller receiving the benefits and burdens of ownership on the Closing Date.

If the Closing shall occur before rents and all other amounts payable by the tenants under the Leases and all other income from the Property have actually been paid for the month in which the Closing occurs, the apportionment of such rents and other amounts and other income shall be upon the basis of such rents, other amounts and other income actually received by Seller. Subsequent to the Closing, if any such rents and other income are actually received by Purchaser, all such amounts shall first be applied to post closing rents due to Purchaser which are past due and the balance shall be immediately paid by Purchaser to Seller for any such amounts due to Seller for the period prior to Closing. Purchaser shall make a good faith effort and attempt to collect any such rents and other amounts and other income not apportioned at the Closing for the benefit of Seller, however, Purchaser shall not be required to expend any funds or institute any litigation in its collection efforts. Nothing in this Section 6.3(a) shall restrict Seller’s right to collect delinquent rents directly from a tenant by any legal means.

If the Closing shall occur before the tax rate or the assessed valuation of the Property is fixed for the then current year, the apportionment of taxes shall be upon the basis of the tax rate for the preceding year applied to the latest assessed valuation. Subsequent to the Closing, when the tax rate and the assessed valuation of the Property is fixed for the year in which the Closing occurs, the parties agree to adjust the proration of taxes and, if necessary, to refund or repay such sums as shall be necessary to effect such adjustment. In the event the Property has been assessed for property tax purposes at such rates as could result in “roll back” taxes upon changes in land usage or ownership of the Property, Purchaser agrees to pay all such taxes and indemnify and save Seller harmless from and against any and all claims and liabilities for such taxes.

If the Closing shall occur before the actual amount of utilities and all other operating expenses with respect to the Property for the month in which the Closing occurs are determined, the apportionment of such utilities and other operating expenses shall be upon the basis of an estimate by Seller of such utilities and other operating expenses for such month. Subsequent to the Closing, when the actual amount of such utilities and other operating expenses with respect to the Property for the month in which the Closing occurs are determined, the parties agree to adjust the proration of such utilities and other operating expenses and, if necessary, to refund or repay such sums as shall be necessary to effect such adjustment.

If at any time following the Closing, the amount of an item listed in Section 6.3(a), (b) or (c) above shall prove to be incorrect (whether as the result of an error in calculation or a lack of complete and accurate information as of the Closing) or otherwise require adjustment as a result of any year-end or periodic reconciliations, the party owing money as a result of such error or adjustment shall promptly pay to the other party the sum necessary to correct such error or make sure adjustment upon receipt of reasonable proof of same, provided that such proof is received by the party from

Page 12

whom payment is to be made on or before one (1) year after the Closing (the “Post Closing Adjustment Period”). In order to enable Seller to determine whether any such delayed adjustment is necessary, Purchaser shall provide to Seller current operating and financial statements for the Property and copies of any correspondence and statements in connection with any reconciliation promptly after the same are prepared, but, in any event, no later than the date one (1) month prior to the expiration of the Post Closing Adjustment Period.

The agreements of Seller and Purchaser set forth in this Section 6.3 shall survive the Closing.

Closing Costs. Except as otherwise expressly provided herein, Seller shall pay, on the Closing Date (i) one half (1/2) of any escrow fees and other customary charges of the Title Company, (ii) the title insurance premium for the base Owner’s Policy (as defined in Section 6.5(b)), and (iii) all transfer taxes. Purchaser shall pay, on the Closing Date, (i) the cost of any endorsements or additional coverage over the base Owner’s Policy, (ii) the cost of the Survey, (iii) all recording costs, (iv) taxes related to Purchaser’s deed to secure debt, if any, and (v) and one half (1/2) of any escrow fees and other customary charges of the Title Company. Except as otherwise provided herein, each party shall pay its own attorneys’ fees.

Purchaser, at Purchaser’s sole expense, may elect to cause the Title Company to amend the survey exception to read “any shortages in area” or elect to obtain additional coverage or endorsements over the base Owner’s Policy, but obtaining such additional coverage or endorsements will not be a condition precedent to Purchaser’s Closing obligations pursuant to this Agreement.

Evidence of Authority. Such organizational and authorizing documents of Seller as shall be reasonably required by the Title Company to evidence Seller’s authority to consummate the transactions contemplated by this Agreement.

Foreign Person. An affidavit of Seller certifying that Seller is not a “foreign person,” as defined in the federal Foreign Investment in Real Property Tax Act of 1980, and the 1984 Tax Reform Act, as amended.

Page 14

Agreement, in which event the Earnest Money shall be refunded to Purchaser, and neither party shall have any further right or obligation hereunder other than the Surviving Obligations, or (b) consummate the Closing, in which latter event all of Seller’s assignable right, title and interest in and to the award of the condemning authority shall be assigned to Purchaser at the Closing and there shall be no reduction in the Purchase Price.

Casualty. Except as provided in Sections 4.2 and 5.1 of this Agreement, Seller assumes all risks and liability for damage to or injury occurring to the Property by fire, storm, accident, or any other casualty or cause until the Closing has been consummated. If the Property, or any part thereof, suffers any damage in excess of $250,000.00 prior to the Closing from fire or other casualty, which Seller, at its sole option, does not elect to repair, Purchaser may either at or prior to Closing (a) terminate this Agreement, in which event the Earnest Money shall be refunded to Purchaser, and neither party shall have any further right or obligation hereunder other than the Surviving Obligations, or (b) consummate the Closing, in which latter event all of Seller’s right, title and interest in and to the proceeds of any insurance covering such damage (less an amount equal to any expenses and costs incurred by Seller to repair or restore the Property and any portion of such proceeds paid or to be paid on account of the loss of rents or other income from the Property for the period prior to and including the Closing Date, all of which shall be payable to Seller), to the extent the amount of such insurance does not exceed the Purchase Price, shall be assigned to Purchaser at the Closing. If the Property, or any part thereof, suffers any damage less than $250,000.00 prior to the Closing, Purchaser agrees that it will consummate the Closing and accept the assignment of the proceeds of any insurance covering such damage plus an amount equal to Seller’s deductible under its insurance policy, such amount to be credited against the Purchase Price at Closing.

DEFAULT

Breach by Seller. In the event that Seller shall fail to consummate this Agreement for any reason, except Purchaser’s default or a termination of this Agreement by Purchaser or Seller pursuant to a right to do so under the provisions hereof, Purchaser, as its sole and exclusive remedy may either (a) terminate this Agreement and receive a refund of the Earnest Money, and neither party shall have any further right or obligation hereunder other than the Surviving Obligations, or (b) pursue the remedy of specific performance of Seller’s obligations under this Agreement; provided, however, that (i) Purchaser shall only be entitled to such remedy if (A) any such suit for specific performance is filed within sixty (60) days after Purchaser becomes aware of the default by Seller, (B) Purchaser is not in default under this Agreement beyond any applicable notice and cure period, (C) Purchaser has tendered an amount equal to three percent (3%) of the Purchase Price to the Title Company in immediately available funds and the Title Company has acknowledged receipt of same, in writing, to Seller, and (D) Purchaser has furnished ten (10) days prior written notice to Seller of its intent and election to seek specific enforcement of this Agreement; and (ii) notwithstanding anything to the contrary contained herein, Seller shall not be obligated to expend any sums to cure any defaults under this Agreement and if Purchaser seeks specific performance under this Agreement, Purchaser agrees to accept the Property in its “AS IS, WHERE IS” condition Purchaser hereby agrees that prior to its exercise of any rights or remedies as a result of any defaults by Seller, Purchaser will first deliver written notice of said default to Seller, and if Seller so elects, Seller shall have the opportunity, but not the obligation, to cure such default within ten (10) days after Seller’s receipt of such notice. In no event whatsoever shall Purchaser file any instrument of record against title to the Property; provided, however, Purchaser may file a lis pendens of this Agreement simultaneously with its filing of a suit for specific performance pursuant to this Section 8.1. Notwithstanding any of the foregoing to the contrary, in no event whatsoever shall Purchaser have the right to seek money damages of any kind as a result of any default by Seller under any of the terms of this Agreement. In no event shall Seller be liable to Purchaser for any punitive, speculative or consequential damages.

Breach by Purchaser.

If Purchaser fails to comply with any of the terms, conditions or obligations of this Agreement, Seller may terminate this Agreement and thereupon shall be entitled to the Earnest Money as liquidated damages (and not as a penalty) and as Seller’s sole remedy and relief hereunder (except

Page 15

for the Surviving Obligations). Seller hereby agrees that prior to its exercise of any rights or remedies as a result of any defaults by Purchaser, Seller will first deliver written notice of said default to Purchaser, and if Purchaser so elects, Purchaser shall have the opportunity, but not the obligation, to cure such default within ten (10) days after Purchaser’s receipt of such notice; provided, however, that in the event Purchaser fails to consummate the closing on the Closing Date, Purchaser shall have the opportunity, but not the obligation, to cure such default within five (5) days of the Closing Date; further provided that Purchaser shall not be entitled to any such cure period for a failure to consummate the closing on the Closing Date pursuant to the terms and conditions of this Agreement if such failure is solely due to Purchaser’s failure to fund the Purchase Price on the Closing Date (other than a delay caused by Purchaser’s lender, if any, in which case Purchaser shall be entitled to the aforementioned five (5) day cure period). Seller and Purchaser have made this provision for liquidated damages because it would be difficult to calculate, on the date hereof, the amount of actual damages for such breach, and Seller and Purchaser agree that these sums represent reasonable compensation to Seller for such breach.

Notwithstanding the provisions of Section 8.2(a) above, the foregoing shall not in any way limit, affect or impair any of Purchaser’s indemnities as provided in Sections 4.2, 6.3(b) or 10.2 of this Agreement.
