NOW, THEREFORE, in consideration of the mutual covenants and agreements contained herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Seller and Purchaser agree as follows:

Seller agrees to sell, and Purchaser agrees to purchase, subject to the terms and conditions contained herein, the Land and the Improvements, together with all of Seller’s right, title and interest in and to:

(a)    (i) all rights of way, tenements, hereditaments, easements, water and water rights, utility capacity and appurtenances, if any, in any way belonging or appertaining to the Land and the Improvements and (ii) all adjoining streets, alleys, roads, parking areas, curbs, curb cuts, sidewalks, landscaping, signage, sewers and public ways (collectively, the “Appurtenant Rights”); and

The Land, Improvements, Appurtenant Rights, Personal Property, Leases, Contracts and Licenses and other property described above are collectively referred to herein as the “Property.”

2.    PURCHASE PRICE.

The purchase price for the Property (the “Purchase Price”) shall be the amount set forth in Line 5 of the Summary Statement. The Purchase Price, plus or minus prorations and adjustments provided for herein, shall be paid in cash or cash equivalent to Seller on or before 2:00 p.m. (Chicago time) on the Closing Date (as hereinafter defined).

3.    EARNEST MONEY.

Within two (2) business days after the Date of Agreement, Purchaser shall deposit into the Escrow (as hereinafter defined) cash or certified funds in the amount set forth in Line 6 of the Summary Statement as an earnest money deposit (together with any interest thereon, the “Earnest Money”). The Earnest Money shall be invested in accordance with Purchaser’s direction and held in accordance with this Agreement and the escrow instructions (the “Escrow”) attached hereto as Exhibit F, and except as otherwise provided herein, all interest earned on the Earnest Money shall remain the property of and be paid to Purchaser. The cost of the investment of the Earnest Money shall be paid from the interest earned thereon before the Title Company pays out such interest or by Purchaser. Upon the closing of the transaction contemplated by this Agreement, the Earnest Money shall be paid to Seller and Purchaser shall receive a credit against the Purchase Price in the amount thereof. If the transaction does not so close, the Earnest Money shall be disbursed in accordance with the terms of this Agreement.

4.    CLOSING.

Subject to terms and conditions of this Agreement, the closing of the transaction contemplated by this Agreement (the “Closing”) shall take place on the date set forth on Line 9 of the Summary Statement (the “Closing Date”) at the offices of the Title Company, or as the parties shall otherwise agree. On the Closing Date, Seller shall transfer and convey title to the Property to Purchaser free and clear of all liens and encumbrances, other than real and personal property taxes not yet due and payable and such title exceptions as may be permitted pursuant to Section 6 below and in accordance herewith and with the Escrow.

5.    ESCROW.

This transaction shall be closed through the Escrow. Upon the creation of the Escrow, anything herein to the contrary notwithstanding, the transfer and conveyance of the Property, the payment of funds and the delivery of the Closing Documents (as defined below) and certain other documents required to close the transaction contemplated by this Agreement shall be made through the Escrow. The Closing shall take place so that simultaneously on the Closing Date, the Title Policy (as hereinafter defined) will be delivered to Purchaser and Seller shall receive the net sale proceeds.

6.    TITLE COMMITMENT.

Seller has delivered or made electronically available to Purchaser a current ALTA Form B title commitment (or such other comparable form as is customary in the state where the Property is located) (the “Title Commitment”) for an owner’s title insurance policy issued by the title company identified in Line 10 of the Summary Statement (the “Title Company”) to be in the amount of the Purchase Price, covering title to the Land, Improvements and Appurtenant Rights, together with legible copies of each of the documents underlying the title exceptions listed therein. Seller shall deliver or cause the Title Company to promptly deliver the Title Commitment and underlying documentation to the surveyor preparing the Survey (as defined below).

On or before the date that is three (3) days before the Approval Date (the “Title Objection Date”), Purchaser will notify Seller in writing (the “Exception Notice”) as to those title exceptions listed in the Title Commitment which it will accept (the “Permitted Exceptions”). If Purchaser fails to provide Seller the Exception Notice on or before the Title Objection Date, the title exceptions listed in the Title Commitment shall be deemed to be Permitted Exceptions and Purchaser shall be deemed to have waived its right to object to such exceptions. Seller shall have the right, but not the obligation, until the sooner of (x) the Closing Date, or (y) the date which is ten (10) days after the date Seller receives the Exception Notice (the sooner of which is hereinafter referred to as the “Title Clearance Date”) to have all title exceptions other than Permitted Exceptions (collectively, the “Unpermitted Exceptions”) removed from the Title Commitment or to have Title Company commit to insure, at Seller’s expense and in a form acceptable to Purchaser in its sole discretion, against any and all loss or damage that may be occasioned by any such Unpermitted Exceptions. If Seller fails on or before the Title Clearance Date to reasonably demonstrate to Purchaser that the Unpermitted Exceptions have been removed, or in the alternative, that Seller has obtained a commitment for title

indemnification or title insurance in a form acceptable to Purchaser in its sole discretion over such Unpermitted Exceptions, then, in either such case, Purchaser shall, as its sole remedy, have the option (the “Title Election”) to either (i) terminate this Agreement, in which case the parties hereto shall have no further obligations hereunder (except for obligations that are expressly intended to survive the termination of this Agreement), and receive a return of the Earnest Money, or (ii) proceed with Closing, in which case the Purchase Price shall be reduced by an amount equal to the aggregate amount of all tax, judgment, mechanics’ and other liens of a definite and ascertainable amount not in excess of $150,000 that constitute Unpermitted Exceptions and Purchaser shall be deemed to have waived any objection to any other Unpermitted Exceptions. Notwithstanding the foregoing, to the extent that an Unpermitted Exception is in the form of lien to secure a borrowing of monies by Seller, any other voluntary lien permitted by Seller as evidenced by Seller’s execution of such lien instrument or a mechanics’ lien for work directly contracted for by Seller in writing, then the $150,000 limitation shall not apply to such lien. If Purchaser fails to notify Seller of its Title Election by the earlier of the Closing Date or five (5) days after the Title Clearance Date, Purchaser shall be deemed to have elected to proceed with the Closing, as set forth in subclause (ii) above.

7.    SURVEY.

Seller has ordered a survey of the Land and Improvements (the “Survey”), to be dated on or about the Date of Agreement and prepared by Prejean & Company, Inc. The Survey shall be certified to Seller, Purchaser, Purchaser’s lender (if any), and Title Company as having been prepared substantially in accordance with the current minimum standard detail requirements for an Urban Land Title Survey jointly adopted by the American Land Title Association and the American Congress of Surveying and Mapping. Seller shall deliver or cause to be delivered a copy of the Survey to Purchaser and to the Title Company.

On or before the date that is three (3) days before the Approval Date (the “Survey Objection Date”), Purchaser shall notify Seller in writing as to those encroachments, gaps, gores and other matters depicted on the Survey, which Purchaser will not accept (the “Survey Defects”). If Purchaser fails to provide Seller with written notice of any Survey Defects on or before the Survey Objection Date, Purchaser shall be deemed to have waived its right to object to matters of survey (and to any related title exceptions raised on the Title Commitment in connection with survey matters). Seller shall have the right, but not the obligation, until the sooner of (x) the Closing Date, or (y) the date which is ten (10) days after the date Seller receives notice of the Survey Defects (the soonest of which is hereinafter referred to as the “Survey Clearance Date”) to have the Survey Defects removed from the Survey or to have Title Company commit to insure, at Seller’s expense and in a form acceptable to Purchaser in its sole discretion, against any and all loss or damage that may be occasioned by any such Survey Defect. If Seller fails on or before the Survey Clearance Date to reasonably demonstrate to Purchaser that the Survey Defects have been removed, or in the alternative, that Seller has obtained a commitment for title indemnification or title insurance in a form acceptable to Purchaser in its sole discretion over such Survey Defect, then, in either case, Purchaser shall, as its sole remedy, have the option (the “Survey Election”) to either (i) terminate this Agreement, in which case the Earnest Money shall be returned to Purchaser and the parties hereto shall have no further obligations hereunder (except for obligations that are expressly intended to survive the termination of this Agreement), or (ii) proceed with Closing, in which case Purchaser shall be

deemed to have waived any objection to such Survey Defects. If Purchaser fails to notify Seller of its Survey Election by the earlier of the Closing Date or five (5) days after the Survey Clearance Date, Purchaser shall be deemed to have elected to proceed with the Closing as set forth in subclause (ii) above.

All rights of Purchaser hereunder or under any of the Closing Documents, with respect to any surviving representation, warranty, covenant or indemnity shall be deemed waived if Purchaser does not, by written notice to Seller, advise Seller of any alleged breach of representation, warranty or covenant, or any alleged indemnification obligation, prior to the expiration of the Survival Period and if not otherwise resolved to Purchaser’s satisfaction, filed suit within three (3) months after the end of the Survival Period.

The provisions of this Section 8(c) shall survive the Closing.

9.    SELLER’S COVENANTS.

From and after the Date of Agreement through the Closing Date, Seller and Seller’s agents shall at Seller’s expense:

(a)    use commercially reasonable efforts to deliver to Purchaser, an estoppel letter substantially in the form attached as Exhibit J (or, with respect to any tenant, such other form or requirements as may be provided for in such tenant’s Lease), certified to Purchaser from each tenant at the Property. However, obtaining such estoppel letters in Acceptable Form (as defined below) in sufficient time to enable Purchaser to conduct a reasonable review thereof prior to the Closing (not less than one (1) business day prior to Closing) from tenants who in the aggregate occupy at least eighty percent (80%) of the aggregate occupied rentable space of the Property shall be the “Estoppel Condition”. “Acceptable Form” shall mean that the estoppel letters do not disclose the existence of any uncured defaults beyond any applicable notice and cure periods and do not contain any information materially inconsistent with the terms of the applicable lease. Promptly after the Date of Agreement, Seller shall prepare the estoppel forms and deliver them via email to Purchaser for review and confirmation that they have been completed in accordance with the applicable Lease provisions.  Purchaser shall have two (2) business days to review and

comment thereon.  Seller shall incorporate and/or reconcile Purchaser’s timely comments, if any, and thereafter Seller shall promptly deliver the estoppels to the applicable tenants. Seller’s failure to satisfy the Estoppel Condition shall in no instance constitute a default by Seller under this Agreement and in the event of such failure, Purchaser’s sole right shall be either to terminate this Agreement in which case the Earnest Money, and all interest earned thereon, shall be returned to Purchaser, or to waive the Estoppel Condition (to the extent not satisfied) and proceed with the Closing. Notwithstanding the foregoing, the parties agree that Seller shall have a one-time right to extend the Closing Date for up to 30 days in order to attempt to satisfy the Estoppel Condition upon the giving of notice of such election to Purchaser at least two (2) business days prior to the then existing Closing Date. In addition, Seller agrees that upon the request of Purchaser prior to the Approval Date, Seller shall deliver to the tenants at the Property, a reasonable form of subordination non-disturbance and attornment agreement prepared by Purchaser (“SNDA”) and shall request that the tenants execute and return the SNDAs prior to Closing. Purchaser expressly agrees that the failure to obtain SNDAs is not a default or breach by Seller under this Agreement nor is the receipt of any SNDAs a precondition to Purchaser’s obligations hereunder.

(b)    maintain the Property in the condition in which it existed as of the Date of Agreement, normal wear and tear and casualty excepted, free from mechanics’ liens, and operate the Property in a manner consistent with current practice and in accordance with all applicable laws, ordinances, rules and regulations affecting the Property;

(c)    keep in existence all fire and extended coverage insurance policies, and public liability insurance policies with respect to the Property that are in existence as of the Date of Agreement;

(d)    not, after the Approval Date, (i) amend, waive any rights under, terminate or extend any Lease, Contract, License or Telecommunications Agreement, (ii) enter into new leases, contracts, licenses and telecommunications agreements, or (iii) apply any security deposits under the Leases, without Purchaser’s prior written consent. However, prior to the Approval Date, and without Purchaser’s consent, Seller shall have the right to enter into new leases, contracts, licenses and telecommunications agreements, amend and extend leases, contracts, licenses and telecommunications agreements, expand demised premises, enforce and terminate leases, contracts, licenses and telecommunications agreements, provided that Seller gives written notice of such activity to Purchaser reasonably promptly thereafter (and, in any event, at least one (1) business day prior to the Approval Date);

(e)    upon at least twenty-four (24) hours’ notice to Seller, permit Purchaser, its engineer, architect or other agents, during normal business hours (or such other times as are reasonable), to enter onto the Land for the purpose of making inspections thereof;

(f)    promptly advise Purchaser in writing of any changes in circumstances that would render the representations and warranties made by Seller herein false or misleading in any material respect;

(g)    upon written notice from Purchaser on or before the Approval Date, give appropriate notices of termination of Contracts designated by Purchaser (but only to the

extent termination is permitted thereunder without a penalty); provided, however, that if the notice period required to terminate such Contracts will not have run prior to Closing, Seller shall assign and Purchaser shall assume any remaining rights and obligations under such Contracts pursuant to the Assignment and Assumption. Notwithstanding the foregoing, Purchaser is not entitled to terminate any of the Contracts referred to in Exhibit H and Purchaser will not be assuming Seller’s property management and leasing agreements with Transwestern;

(h)    not market, solicit, negotiate, or enter into any agreement with any party other than Purchaser for the sale or transfer of any interest (other than leasing in accordance with this Agreement) in the Property;

(i)    keep Purchaser reasonably apprised of leasing activity at the Property and serious negotiations and documentation relating thereto.

Notwithstanding anything to the contrary contained in Section 9(g) above, Purchaser shall not have the right to request Seller to terminate the telecommunications licenses, riser management agreements or rooftop contracts described on Exhibit I attached hereto (the “Telecommunications Agreements”), and at Closing Seller shall assign to Purchaser, and Purchaser shall assume from Seller the Telecommunications Agreements pursuant to the Assignment and Assumption.

10.    APPROVAL DATE.

(a)    During the period (the “Inspection Period”) from the Date of Agreement through the Approval Date identified in Line 8 of the Summary Statement (the “Approval Date”), (A) Seller shall permit Purchaser to examine, at all reasonable times, the books and records (including without limitation historical financial and operating statements) in Seller’s possession or control relating to the Property, (B) Purchaser shall have the right, at all reasonable times, to (I) inspect the Land, Improvements, Appurtenant Rights and Personal Property, (II) review the Leases, the Contracts and the Licenses, (III) interview the tenants and any property manager and leasing agent, and (IV) conduct geophysical feasibility tests of the Property and environmental audit or audits of the Property, including sampling, and (C) Purchaser shall be given complete access to the Property for the purpose of making such tests, inspections and investigations. All of the foregoing inspections, reviews, interviews, tests, investigations and studies to be conducted under this Section 10(a) by Purchaser shall be subject to the following:

(i)    Such studies, tests, inspections, interviews, reviews and investigations shall take place during normal business hours upon reasonable notice to Seller or its designated agents and Seller’s consent shall be required prior to the performance of any drilling, boring or other invasive sampling, testing or procedures and Seller shall be entitled to be present during any such investigation or interview;

(ii)    In the event the Closing does not occur, Purchaser shall, upon written request, promptly return to Seller any documents obtained from Seller or Seller’s agents;

(iii)    Purchaser shall not suffer or permit any lien, claim or charge of any kind whatsoever to attach to the Property or any part thereof caused directly or indirectly by the activities of Purchaser, its agents, engineers, employees, contractors, surveyors, or invitees; and

(iv)    Such tests, investigations and studies shall be at Purchaser’s sole cost and expense and shall not unreasonably interfere with the operation of the Property. In the event of any damage to the Property caused by Purchaser, its agents, engineers, employees, contractors or surveyors (including without limitation pavement, landscaping and surface damage), Purchaser shall pay the reasonable cost incurred by Seller to restore the Property to substantially the condition existing prior to the performance of such tests, investigations or studies; such obligation shall survive the termination of this Agreement.

Purchaser shall defend, indemnify and hold Seller harmless from any and all liability, cost and expense (including without limitation reasonable attorneys’ fees, court costs and costs of appeal) suffered or incurred by Seller for death or injury to persons or property caused by or arising out of Purchaser’s reviews, interviews, investigations, tests, studies and inspections of the Property excluding any such liability, cost or expense resulting directly from and to the extent of the negligence or willful misconduct of Seller or its agents, employees or contractors or Purchaser’s mere discovery of existing conditions on the Property without exacerbating such condition; such obligation shall survive indefinitely the Closing or the earlier termination of this Agreement. Prior to commencing any such tests, studies and investigations, Purchaser shall maintain and shall furnish to Seller a certificate of insurance evidencing comprehensive general public liability insurance insuring the person, firm or entity performing such tests, studies and investigations and listing Seller and Purchaser as additional insureds thereunder. If, in the sole discretion and at the sole election of Purchaser, the Property and/or any of said tests, inspections or investigations are unsatisfactory to Purchaser, in any manner or for any reason in Purchaser’s sole discretion, including without limitation for reasons relating to restrictions on use of the Property, matters relating to zoning, government approvals, title, survey, appraised value or other matters impacting the condition or value of the Property, Purchaser may terminate this Agreement as provided below. If Purchaser notifies Seller, in writing, on or before 5:00 p.m. (Chicago time) on the Approval Date of Purchaser’s election to terminate this Agreement, Purchaser shall, upon written request and provided Seller is not then in default under the terms and provisions of this Agreement, promptly deliver to Seller copies of all documents, studies and reports (without any representation or warranty) obtained by Purchaser in connection with its due diligence (which obligation shall survive the termination of this Agreement), this Agreement shall terminate, the Earnest Money and all interest earned thereon shall be delivered to Purchaser and the parties hereto shall have no further obligations hereunder (except for obligations that are expressly intended to survive termination of this Agreement). If Purchaser fails to notify Seller, in writing, on or before 5:00 p.m.

(Chicago time) on the Approval Date, of Purchaser’s election to terminate this Agreement, Purchaser’s right to terminate this Agreement under this Section 10(a) shall expire.

(b)    The obligation of Purchaser to close the transaction contemplated by this Agreement is further subject to the condition that: (i) all of the representations and warranties of Seller contained in this Agreement are true and correct, in all material respects, at the Date of Agreement and as of the Closing Date, (ii) the Estoppel Condition is satisfied, (iii) the Title Company is committed to issue the Title Policy, and (iv) all of the obligations and duties of Seller to be performed hereunder and per the Escrow on or before the Closing Date have been substantially completed in a timely manner. Purchaser shall give written notice to Seller within five (5) days after Purchaser’s receipt of any notice disclosing that any Seller representation and warranty is no longer true and correct; provided, however, that Purchaser’s failure to give such written notice shall in no instance constitute a default by Purchaser under this Agreement but shall instead only serve to bar Purchaser from raising such matter as a failure of a condition precedent to Purchaser’s obligation to close the transaction. Purchaser’s election to proceed with the Closing shall result in Purchaser’s waiver of any remedy resulting from the incorrectness in such representation or warranty or from the incorrectness in any other representation or warranty of Seller of which Purchaser shall have knowledge at or prior to Closing. The foregoing waiver shall survive the Closing.

(c)    Prior to the Closing, all information, data and documents relating to the Property (including without limitation those furnished pursuant to the terms and provisions of Section 11(a)) obtained by Purchaser from Seller or any other party or discovered by Purchaser during the term of this Agreement (collectively, the “Confidential Information”) shall be maintained by Purchaser in strict confidence and shall not be revealed to any other party, except Purchaser’s employees, contractors, investors, attorneys and financial advisors (“Purchaser’s Representatives”) and as required by law.  Purchaser shall be liable for any disclosure of the Confidential Information by any of Purchaser’s Representatives.  The provisions of this Section 10(c) shall survive the termination of this Agreement.  Notwithstanding the foregoing and anything to the contrary in this Agreement, nothing contained herein shall impair Purchaser’s (or its permitted assignee’s) right to disclose information relating to this Agreement or the Property (i) to any due diligence representatives and/or consultants that are engaged by, work for or are acting on behalf of, any securities dealers and/or broker dealers evaluating Purchaser or its permitted assignees, (ii) in connection with any filings (including any amendment or supplement to any S-11 filing) with governmental agencies (including the SEC) by any REIT holding, or that is considering holding, an interest (direct or indirect) in any permitted assignee of Purchaser, and (iii) to any broker/dealers in the Purchaser’s or any REIT's broker/dealer network and any of the REIT’s or Purchaser’s investors.

11.    DELIVERY OF DOCUMENTS.

(a)    During the Inspection Period, Seller shall provide Purchaser with access to, or otherwise make available to Purchaser the following, to the extent in the possession or control of Seller:

(i)    the most recent (for the prior twelve (12) months) real estate and personal property tax bills, notices of assessed valuation and utility bills relating to the Property;

(ii)    certificates of occupancy, floor plans, “as built” or working drawings, site plans, specifications and the most recent survey and title policy relating to the Property;

(iii)    the Leases and any material correspondence with respect thereto;

(iv)    the Contracts and Licenses;

(v)    statements of operations and accounts receivable aging reports for the past three (3) complete calendar years and year to date for the current year and general ledgers maintained or prepared for the Property;

(vii)    all material correspondence and notices to or from any taxing authorities, governmental agencies, utilities or vendors with respect to the Property:

(xvii)    such other documents, instruments, gap undertakings, consents or agreements as may be reasonably requested by the Title Company or the escrow agent, in order to issue to Purchaser a TLTA T-1 owner’s title insurance policy (the “Title Policy”) in the amount of the Purchase Price, subject only to the Permitted Exceptions and any Purchaser Exceptions (as defined below); it being understood that the Title Policy may be issued at Closing in the form of the Title Commitment or a pro forma title policy, hand-marked and initialed by the Title Company, and dated as of the Closing Date, so as to be the equivalent of the Title Policy.

(c)     At least one (1) business day prior to the Closing Date (unless a different time is specified below), Purchaser shall deliver the following to Seller or the Title Company, as appropriate, in form and substance reasonably acceptable to Seller, all duly executed by Purchaser, where appropriate, each of which shall be a condition precedent to Seller’s obligation to close the transaction contemplated by this Agreement:

12.    FIRE OR CASUALTY.

In the event of damage to the Property by fire or other casualty prior to the Closing Date, Seller shall promptly notify Purchaser of such fire or other casualty.  If the fire or other casualty causes damage that is Material (as defined below), then Purchaser may elect, by written notice to be delivered to Seller on or before the sooner of (i) the tenth (10th) day after Purchaser’s receipt of such notice or (ii) the Closing Date, to either:  (a) close the transaction contemplated by this Agreement and receive all insurance claims and proceeds payable to Seller as a result of such fire or other casualty, with the same being paid or assigned to Purchaser at Closing together with a credit for any applicable deductibles or (b) terminate this Agreement, and promptly receive a return of the Earnest Money in which case the parties hereto shall have no further obligations hereunder (except for obligations that are expressly intended to survive the termination of this Agreement).  If the damage to the Property by fire or other casualty prior to the Closing Date is not Material, then Purchaser shall not have the right to terminate its obligations under this Agreement by reason thereof, and Seller shall have the right to elect to either repair and restore the Property if such repair or restoration may be completed prior to the Closing Date or to assign and transfer to Purchaser on the Closing Date all of Seller’s right, title and interest in and to all insurance proceeds paid or payable to Seller on account of such fire or casualty together with a credit for any applicable deductibles or to credit the estimated cost to repair and restore the Property (as determined by Seller and Purchaser in good faith). For purposes of this Section 12, “Material” shall mean: damage to the Property by fire or other casualty which would (a) cost in excess of 5% of the Purchase Price to repair (as determined by Seller and Purchaser in good faith), (b) cause access to or parking on the Property to be materially and adversely affected for a period of more than 180 days, (c) entitle any tenant(s) whose aggregate square footage of leased and occupied premises exceeds 40,000 rsf to terminate the applicable Lease and such tenant(s) have not waived the right to so terminate, or (d) result in any uninsured loss and for which Purchaser will not receive, at Seller’s election, a credit in the amount of the uninsured loss.

13.    CONDEMNATION.

If, prior to the Closing Date, all or any part of the Property is taken by condemnation or a conveyance in lieu thereof, or if Seller receives notice of a condemnation proceeding with respect to the Property, then Seller shall promptly notify Purchaser of such condemnation or conveyance in lieu thereof. If the taking or threatened taking involves a material portion of the Property (hereinafter defined), Purchaser may elect, by written notice to be delivered to Seller on or before the sooner of (i) the tenth (10th) day after Purchaser’s receipt of such notice, or (ii) the Closing Date, to terminate this Agreement, in which event the Earnest

Money shall be returned to Purchaser, and the parties hereto shall have no further obligations hereunder (except for obligations that are expressly intended to survive the termination of this Agreement). If Purchaser elects to close this transaction notwithstanding such taking or condemnation, Purchaser shall be entitled to any award given to Seller as a result of such condemnation proceedings, with the same being paid or assigned to Purchaser at Closing. As used in this Section 13, a “material portion of the Property” means (a) any part of the Property reasonably required for the operation of the Property in the manner operated on the date hereof, (b) cause access to or parking on the Property to be materially and adversely affected for a period of more than 180 days, (c) inability to comply with applicable zoning, (d) entitles any tenant(s) whose aggregate square footage of leased and occupied premises exceeds 40,000 rsf to terminate the applicable Lease and such tenant(s) have not waived the right to so terminate, or (e) valued in excess of 5% of the Purchase Price (as determined by Seller and Purchaser in good faith). If any taking or threatened taking does not involve a material portion of the Property, Purchaser shall be required to proceed with the Closing, in which event Seller shall assign to Purchaser any award given to Seller (or the right to receive any such award) as a result of such condemnation proceedings.

14.    ADJUSTMENTS AND PRORATIONS.

Adjustments and prorations with respect to the Property shall be computed and determined between the parties as of 12:01 a.m. on the Closing Date (as if Purchaser were vested with title to the Property during the entire Closing Date) as follows:

(a)    General real estate taxes, special assessments and personal property taxes shall be prorated as of the Closing Date based on the then current taxes (if known, based on final tax bills for such period -- and if not known, based on the most recent ascertainable taxes) and the special assessments due and owing prior to Closing, and Seller or Purchaser shall receive a credit at Closing, as appropriate. Without affecting the obligations set forth in this Section 14(a), the prorations for real and personal property taxes shall be equitably adjusted to reflect any such items directly paid by tenants to the applicable third-party payees). If final taxes or special assessments are not known as of the Closing, the parties agree to reprorate when such amounts become known.

(b)    All rents and other sums receivable from tenants of the Property, which were earned and attributable to the period prior to the Closing Date, will be retained by Seller to the extent that such rents have been collected on or before the Closing Date. Rents earned and attributable to the period beginning on the Closing Date and thereafter will be paid to Purchaser by the tenants, or credited to Purchaser at Closing (if such rents are received by Seller prior to the Closing Date). Seller shall receive no closing proration for rents delinquent as of the Closing Date. All payments from tenants, on account of rent or otherwise, received by Seller after the Closing Date, whether attributable to the period prior to or after the Closing Date, shall be deemed to be held in trust by Seller for Purchaser and shall be promptly delivered to Purchaser by Seller for application as provided in this Section 14(b). All payments from tenants, on account of rent or otherwise, received after the Closing Date by Purchaser and all amounts received from Seller by Purchaser pursuant to the immediately preceding sentence, shall be applied first to rent or other sums then due under the Leases attributable to the period beginning on the Closing Date and continuing

thereafter, and then to payment to Seller on account of rents which were earned and attributable to the period prior to the Closing Date but which were not paid prior to Closing. For a period of six (6) months following the Closing Date, Purchaser shall continue to bill existing tenants for accounts receivable and delinquent rents attributable to the Property for the period prior to the Closing Date. Any customary out-of-pocket costs incurred by Purchaser in collection of delinquent rentals shall be deducted by Purchaser prior to the payment to Seller on account of delinquent rentals as provided herein. Seller shall have the right to contact tenants to request payment of delinquent rentals after the Closing Date and institute legal proceedings to collect such delinquent rentals, but shall have no right to evict any tenant. Any such enforcement or collection efforts by Seller shall be at Seller’s sole expense. Notwithstanding anything herein to the contrary, at Closing, Purchaser shall be entitled to receive a credit against the Purchase Price equal to any remaining so-called “free rent” under the Leases for tenants HCSC, Drilling Info, Quanex and Sound Financial.

(c)    On the Closing Date, Seller shall deliver to Purchaser in cash, as a credit against the Purchase Price or as an adjustment to the prorations provided for elsewhere in this Section 14, as appropriate, an amount equal to all cash security deposits made by tenants occupying the Property which were paid to Seller by such tenants and which shall not have been applied by Seller or otherwise pursuant to the Leases, together with interest owing thereon pursuant to the applicable Lease, if any, and together with a listing of the tenants to which such deposits and interest are owing. With respect to any security deposit which is evidenced by a letter of credit, Seller shall (i) deliver to Purchaser at Closing such original letter of credit, and (ii) execute and deliver at Closing such other instruments as the issuer of such letter of credit shall reasonably require in order to cause the named beneficiary under such letter of credit to be changed to Purchaser.

(d)    All amounts payable, owing or incurred in connection with the Property under the Contracts to be assumed by Purchaser under the Assignment and Assumption shall be prorated as of the Closing Date.

(e)    All utility deposits, if any, may be withdrawn by and refunded to Seller, and Purchaser shall make its own replacement deposits for utilities as may be required by the respective utilities involved.

(f)    The Earnest Money shall be paid to Seller at Closing and Purchaser shall be entitled to a credit against the Purchase Price in the amount thereof.

(g)    All utility charges that are not separately metered to tenants shall be prorated to the Closing Date and Seller shall obtain a final billing therefor and pay any amounts owing therein for the period prior to the Closing Date and Purchaser shall pay any amounts owing for the period on and after the Closing Date. To the extent that utility bills cannot be handled in the foregoing manner, they shall be prorated as of the Closing Date based on the most recent bills available and reprorated when such final bills become known.

(h)    Purchaser shall pay its pro rata share (based on the applicable commencement date of the lease and the lease term) of all leasing commissions and tenant improvement costs payable with respect to Leases entered into after the Date of Agreement. If Seller has paid such amounts prior to the Closing Date, Purchaser shall reimburse Seller for Purchaser’s pro rata share of such payments at Closing. If Seller has not paid such amounts prior to the Closing Date, Purchaser shall receive a credit against the Purchase Price at Closing in an amount equal to Seller’s pro rata share of such amounts.

(i)    Seller and Purchaser agree that as soon as reasonably possible after the close of the calendar year of the Property, the parties shall undertake a final master reconciliation of CAM, taxes and other pass-throughs and additional rent with respect to the Leases and the Property. Purchaser shall prepare the tenant reconciliations for Seller’s review and approval. Purchaser shall transmit such information to the tenants. To the extent the reconciliation concludes that Seller owes any tenants at the Property reimbursements due to the over collection of CAM, taxes and other pass-throughs and additional rent for 2012, then Seller shall pay such amount to Purchaser upon the delivery of the reconciliation. To the extent the reconciliation concludes that Seller is owed amounts from any tenants at the Property due to the under collection of CAM, taxes and other pass-throughs and additional rent for 2012, then Purchaser shall promptly pay over to Seller all such amounts received by Purchaser from any such tenants.

(j)    Unless provided otherwise hereinabove, such other items as are customarily prorated in a purchase and sale of the type contemplated hereunder shall be prorated as of the Closing Date.

(k)    The provisions of this Section 14 shall survive for the Survival Period.

15.    CLOSING COSTS.

Seller shall pay: (a) the costs of recording any releases required to clear title to the Property, (b) Seller’s attorneys’ fees, (c) one-half of all escrow closing fees and costs, (d) the costs of any curative endorsements or curative deletions to the Title Policy, (e) the basic premium for the Title Policy (excluding the premium for the deletion of the area and boundary exception), and (f) the costs of the Survey. Purchaser shall pay: (i) the costs of recording the deed and related stamp tax, sales tax, documentary transfer tax or other tax imposed on the transfer of the Property, (ii) the costs of any non-curative endorsements or deletions to the Title Policy, (iii) if desired by Purchaser, the premium for the deletion of the area and boundary exception from the Title Policy, (iv) the costs of any Purchaser requested changes, updates or supplements to the Survey, (v) Purchaser’s attorneys’ fees, and (vi) one-half of all escrow closing fees and costs.

16.    POSSESSION.

Possession of the Property shall be delivered to Purchaser at Closing, free and clear of all liens and claims other than Permitted Exceptions, Purchaser Exceptions and the rights of the tenants identified on the Rent Roll and of the licensees set forth on Exhibits E and I, in

the same condition as it exists on the Date of Agreement, ordinary wear and tear excepted and except as provided in Sections 12 and 13 hereof. Purchaser shall have the right to inspect the Property within three (3) days prior to Closing to verify that the condition of the Property is as required under this Agreement.

17.    DEFAULT.

If Seller defaults hereunder prior to Closing and fails to cure such default within three (3) days after written notice of such default, or if prior to Closing it is determined that the representations and warranties set forth in this Agreement shall not be true and correct in all material respects on the Date of Agreement and as of the Closing Date, then Purchaser’s sole remedy shall be to either (a) terminate this Agreement and receive a return of the Earnest Money (less $100 which shall be paid to Seller in any event), in which event each of the parties hereto shall be relieved of any further obligation to the other arising by virtue of this Agreement (except for obligations that are expressly intended to survive the termination of this Agreement), or (b) pursue specific performance of this Agreement. In no event shall Seller be liable for any actual, special, punitive, speculative or consequential damages if the Closing does not occur. Notwithstanding the foregoing, if the Closing does not occur due to Seller’s willful material default or due to Seller’s failure to remove liens from title in excess of $150,000 pursuant to Section 6, then in addition to its rights set forth above, Purchaser shall be entitled to recover from Seller its actual demonstrable costs associated with the transaction contemplated by this Agreement up to $75,000. If the Closing occurs, in no event shall Seller be liable for any special, punitive, speculative or consequential damages, nor shall Seller’s liability under any representation, warranty, certification, covenant, agreement, proration, reproration, obligation or indemnity made hereunder or under any of the Closing Documents or otherwise in connection with the transactions contemplated herein exceed One Million Dollars ($1,000,000) in the aggregate (the “Seller’s Maximum Liability”). Prorations and reprorations under this Agreement and Seller’s obligations under Section 19 are not subject to Seller’s Maximum Liability. None of Seller’s partners, members, managers, officers, agents or employees shall have any personal liability of any kind or nature or by reason of any matter or thing whatsoever under, in connection with, arising out of or in any way related to this Agreement, the Closing Documents or the transactions contemplated herein, and Purchaser waives for itself and for anyone who may claim by, through or under Purchaser any and all rights to sue or recover on account of any such alleged personal liability. If Purchaser defaults hereunder and fails to cure such default within three (3) days of written notice of such default and the Closing does not occur as a result thereof, this Agreement shall terminate and Seller shall retain the Earnest Money and any interest thereon as liquidated damages in full settlement of all claims against Purchaser (with the exception of claims against Purchaser related to obligations which are expressly intended to survive the termination of this Agreement). The parties agree that the amount of actual damages that Seller would suffer as a result of Purchaser’s default would be extremely difficult to determine and have agreed, after specific negotiation, that the amount of the Earnest Money is a reasonable estimate of Seller’s damages and is intended to constitute a fixed amount of liquidated damages in lieu of other remedies available to Seller and is not intended to constitute a penalty. The provisions of this Section 17 shall survive the Closing.

18.    NOTICES.

Any notice, approval, demand, request or other communication which either party hereto may be required or may desire to give under this Agreement shall be in writing and shall be deemed to have been properly given if (a) hand delivered (effective upon delivery), (b) sent by a nationally recognized overnight delivery service (effective one (1) business day after delivery to such courier for overnight service), (c) sent by facsimile (effective upon confirmation of transmission), or (d) sent by email (effective only upon receipt by sender of a reply email evidencing receipt), in each case, prepaid and addressed in accordance with Line 11 or Line 12 (as applicable) of the Summary Statement or to such other or additional addresses as either party might designate by written notice to the other party. Counsel for a party may give notice or demand on behalf of such party, and such notice or demand shall be treated as being sent by such party.

19.    BROKERS.

Each of Seller and Purchaser represents and warrants to the other that it has not dealt with any brokers, finders or agents with respect to the transaction contemplated hereby other than the broker(s) set forth in Line 13 of the Summary Statement. Seller shall be responsible for all fees, commissions and other amounts due to Seller’s Broker as a result of the transactions contemplated herein. Each party agrees to indemnify, defend and hold harmless the other party, its successors, assigns and agents, from and against the payment of any commission, compensation, loss, damages, costs, and expenses (including without limitation attorneys’ fees and costs) incurred in connection with, or arising out of, claims for any broker’s, agent’s or finder’s fees of any person claiming by or through such party, except that Purchaser does not indemnify Seller for claims by Seller’s Broker. The obligations of Seller and Purchaser under this Section 19 shall survive the Closing and the termination of this Agreement.

20.    LEASING COSTS AND MANAGEMENT.

Except as provided in Section 14(h) hereof, Seller agrees to pay or discharge at or prior to Closing all leasing commissions, costs for tenant improvements, legal fees and other costs and expenses (collectively, “Leasing Costs”) that are due and payable as of the Closing Date with respect to Leases in force as of or prior to Closing including, without limitation, Leasing Costs identified as Seller’s lease obligations on Exhibit H; provided, however, that Seller shall have no obligation to pay, and as of Closing, Purchaser shall assume the obligation to pay (i) all Leasing Costs identified as Purchaser’s lease obligations on Exhibit H, and (ii) all Leasing Costs owed by Purchaser pursuant to the terms of Section 14(h) above. On the Closing Date, Seller shall deliver evidence reasonably satisfactory to Purchaser that any current management or leasing agreements for the Property shall have been terminated (or notice of termination given). Notwithstanding anything herein to the contrary, Purchaser agrees that even though Seller shall terminate its leasing agreements so that Purchaser shall not take an assignment and assumption thereof, that in the event Purchaser enters into a lease after Closing with a tenant which appears on the so-called protected list during the “tail” period as provided in any such leasing agreement, that Purchaser (and not Seller) shall be responsible for any commissions due under such leasing agreement. Seller shall promptly deliver to Purchaser any protected lists received from the leasing agents under and pursuant to such leasing agreements.

The obligations of Seller and Purchaser under this Section 20 shall survive the Closing and the termination of this Agreement.

21.    “AS IS” SALE.

EXCEPT FOR THE EXPRESS REPRESENTATIONS AND WARRANTIES OF SELLER SET FORTH HEREIN AND IN THE CLOSING DOCUMENTS, PURCHASER ACKNOWLEDGES AND AGREES THAT IT WILL BE PURCHASING THE PROPERTY BASED SOLELY UPON ITS INSPECTIONS AND INVESTIGATIONS OF THE PROPERTY, AND THAT PURCHASER WILL BE PURCHASING THE PROPERTY “AS IS” AND “WITH ALL FAULTS”, BASED UPON THE CONDITION OF THE PROPERTY AS OF THE DATE OF AGREEMENT, ORDINARY WEAR AND TEAR AND LOSS BY FIRE OR OTHER CASUALTY OR CONDEMNATION EXCEPTED AND THAT SELLER MAKES NO WARRANTY OR REPRESENTATION, EXPRESS OR IMPLIED, OR ARISING BY OPERATION OF LAW, INCLUDING, BUT NOT LIMITED TO, ANY WARRANTY OF CONDITION, HABITABILITY, MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE, IN RESPECT OF THE PROPERTY. WITHOUT LIMITING THE FOREGOING, PURCHASER ACKNOWLEDGES THAT, EXCEPT AS MAY OTHERWISE BE SPECIFICALLY SET FORTH ELSEWHERE IN THIS AGREEMENT OR IN THE CLOSING DOCUMENTS, NEITHER SELLER NOR ITS CONSULTANTS, BROKERS OR AGENTS HAS MADE ANY REPRESENTATIONS OR WARRANTIES OF ANY KIND UPON WHICH PURCHASER IS RELYING AS TO ANY MATTERS CONCERNING THE PROPERTY, INCLUDING BUT NOT LIMITED TO: (I) THE CONDITION OF THE LAND OR ANY IMPROVEMENTS COMPRISING THE PROPERTY; (II) THE EXISTENCE OR NON-EXISTENCE OF ANY POLLUTANT, TOXIC WASTE AND/OR ANY HAZARDOUS MATERIALS OR SUBSTANCES; (III) ECONOMIC PROJECTIONS OR MARKET STUDIES CONCERNING THE PROPERTY, OR THE INCOME TO BE DERIVED FROM THE PROPERTY; (IV) ANY DEVELOPMENT RIGHTS, TAXES, BONDS, COVENANTS, CONDITIONS AND RESTRICTIONS AFFECTING THE PROPERTY; (V) THE NATURE AND EXTENT OF ANY RIGHT OF WAY, LEASE, LIEN, ENCUMBRANCE, LICENSE, RESERVATION OR OTHER TITLE MATTER; (VI) WATER OR WATER RIGHTS, TOPOGRAPHY, GEOLOGY, DRAINAGE, SOIL OR SUBSOIL OF THE PROPERTY; (VII) THE UTILITIES SERVING THE PROPERTY; (VIII) THE SUITABILITY OF THE PROPERTY FOR ANY AND ALL ACTIVITIES AND USES WHICH PURCHASER MAY ELECT TO CONDUCT THEREON; OR (IX) THE COMPLIANCE OF THE PROPERTY WITH ANY ZONING, ENVIRONMENTAL, BUILDING OR OTHER LAWS, RULES OR REGULATIONS AFFECTING THE PROPERTY. EXCEPT FOR THE EXPRESS REPRESENTATIONS AND WARRANTIES OF SELLER SET FORTH HEREIN AND IN THE CLOSING DOCUMENTS, SELLER MAKES NO REPRESENTATION OR WARRANTY THAT THE PROPERTY COMPLIES WITH THE AMERICANS WITH DISABILITIES ACT OR ANY FIRE CODE OR BUILDING CODE. EXCEPT FOR THE BREACH OF ANY EXPRESS REPRESENTATIONS AND WARRANTIES OF SELLER SET FORTH HEREIN AND IN THE CLOSING DOCUMENTS, PURCHASER HEREBY RELEASES SELLER FROM ANY AND ALL LIABILITY IN CONNECTION WITH ANY CLAIMS THAT PURCHASER MAY HAVE AGAINST SELLER RELATING DIRECTLY OR INDIRECTLY TO THE EXISTENCE OF ASBESTOS OR HAZARDOUS MATERIALS OR SUBSTANCES ON, OR ENVIRONMENTAL CONDITIONS OF, THE PROPERTY,

WHETHER KNOWN OR UNKNOWN, AND PURCHASER HEREBY AGREES NOT TO ASSERT ANY CLAIMS FOR CONTRIBUTION, COST RECOVERY OR OTHERWISE, AGAINST SELLER, RELATING DIRECTLY OR INDIRECTLY TO THE EXISTENCE OF ASBESTOS OR HAZARDOUS MATERIALS OR SUBSTANCES ON, OR ENVIRONMENTAL CONDITIONS OF, THE PROPERTY, WHETHER KNOWN OR UNKNOWN. As used herein, the terms “Hazardous Substances” and “HAZARDOUS MATERIALS OR SUBSTANCES” mean (i) hazardous wastes, hazardous substances, hazardous constituents, toxic substances or related materials, whether solids, liquids or gases, including but not limited to substances defined as “hazardous wastes,” “hazardous substances,” “toxic substances,” “pollutants,” “contaminants,” “radioactive materials,” or other similar designations in, or otherwise subject to regulation under, the Comprehensive Environmental Response, Compensation and Liability Act of 1980, as amended, 42 U.S.C. §9601 et seq.; the Toxic Substance Control Act, 15 U.S.C. §2601 et seq.; The Hazardous Materials Transportation Act, 49 U.S.C. §1802; the Resource Conservation and Recovery Act, 42 U.S.C. §9601. et seq.; the Clean Water Act, 33 U.S.C. §1251; the Safe Drinking Water Act, 42 U.S.C. §300f et seq.; the Clean Air Act, 42 U.S.C. §7401 et seq.; and in any permits, licenses, approvals, plans, rules, regulations or ordinances adopted, or other criteria and guidelines promulgated pursuant to the preceding laws or other similar federal, state or local laws, regulations, rules or ordinance now or hereafter in effect relating to environmental matters (collectively, “Environmental Laws”); and (ii) any other substances, constituents or wastes subject to any applicable federal, state or local law, regulation or ordinance, including any Environmental Law, now or hereafter in effect, including but not limited to (A) petroleum, (B) refined petroleum products, (C) waste oil, (D) waste aviation or motor vehicle fuel and (E) asbestos. Purchaser acknowledges that having been given the opportunity to inspect the Property, Purchaser is relying solely on its own investigation of the Property and not on any information provided or to be provided by Seller except the express representations and warranties of Seller set forth in this Agreement and in the Closing Documents. Purchaser further acknowledges that the information provided and to be provided with respect to the Property was obtained from a variety of sources, and that Seller (x) has not made any independent investigation or verification of such information and (y) makes no representations as to the accuracy or completeness of such information, except as provided herein. The provisions of this Section 21 shall survive the Closing Date.

22.    ASSIGNMENT.

Purchaser shall not have the right to assign this Agreement or any interest herein without the express written consent of Seller, and in the event Seller consents to such assignment, Purchaser shall remain liable for, and the assignee shall assume, all obligations of Purchaser hereunder. Notwithstanding the foregoing, provided that Purchaser notifies Seller in writing in sufficient time to allow the Closing to occur without delay or unreasonable burden, Purchaser may assign this Agreement to an entity controlling, controlled by or under common control with Purchaser or which is a REIT or owned directly or indirectly by a REIT for which Purchaser or its affiliates acts as the investment advisor, however, such assignment shall not release Purchaser hereunder. Seller acknowledges that the transaction contemplated hereby may be part of a so-called 1031 exchange for Purchaser. Seller agrees to cooperate in such exchange, including permitting any necessary assignments, provided that Seller shall not be obligated to incur material expense or increase its liability hereunder or otherwise as a result of such exchange.
