If, for the fiscal tax year in which the Closing is held, or any prior year, there are any tax protests filed, or abatement application proceedings pending at any time prior to the Closing with reference to the Property, Seller shall have the right to settle such protests or proceedings as long as such settlement does not include any agreement as to the valuation of the Property for real estate tax purposes for the period after the Closing. Otherwise, Seller shall not settle the same without Purchaser’s prior written consent. All amounts recovered as a result thereof, whether by settlement or otherwise, shall, net of attorneys’ fees and other expenses, be apportioned as of the Closing for the fiscal tax year in which the Closing is held, and paid, when received, to the parties entitled thereto; provided, however, that to the extent any such amounts are payable to Tenant pursuant to the terms of the Lease, such amounts shall be promptly paid over to such Tenant. The parties agree to execute any papers or take such steps, either before or after any Closing, as may be necessary to carry out the intention of the foregoing.

          (b) Title Insurance. Purchaser shall pay all title examination fees of Title Company, the premium for the cost of the Title Insurance Policy with endorsements and all costs of any lender’s title insurance policy, if applicable.

          (c) Survey Costs. Purchaser shall pay all costs of the Survey.

          (d) Closing Fee. Seller and Purchaser will each pay one-half of any reasonable and customary closing fee charged by the Title Company.

          (e) Transfer Tax. The Virginia Grantor Tax applicable to the sale, and any additional transfer taxes including, without limitation, state and county transfer or recordation taxes, regarding the Deed to be delivered by Seller under this Agreement shall be split equally between Seller and Purchaser. Purchaser shall pay for any mortgage registration or recording taxes in connection with any loan documentation or mortgages recorded by Purchaser and/or Purchaser’s lender, if any.

          (f) Collected Rents. All collected net rent (excluding Operating Expense Pass-Throughs) and other collected income under the Lease shall be prorated as of the Closing. Seller shall be charged with any rent and other income collected by Seller before Closing but applicable to any period of time after Closing. Uncollected rent and other income shall not be prorated. Purchaser shall apply rent and other income from Tenant that are collected by Purchaser after the Closing unless the Tenant properly identifies the payment as being for a specific item, in the following order: (i) first, to Purchaser’s reasonable costs of collection incurred with respect to such Tenant, (ii) second, to Purchaser in payment of the current rent due under such Lease, (iii) third, to Purchaser in payment of delinquent rent due under such Lease for the period from and after the Closing, and (iv) fourth, to Seller in payment of rent coming due and payable prior to the Closing. Any prepaid rents for the period on or following the Closing Date shall be paid over by Seller to Purchaser. Purchaser will make commercially reasonable efforts, without suit, to collect any rents relating to the period before Closing. Seller shall have the right to sue delinquent Tenants for delinquent rent so long as Seller does not cause a termination of any Lease.

          (g) Operating Expense Pass-Throughs. Seller, as landlord under the Lease, is currently collecting from Tenant under the Lease additional rent and an expense stop to cover taxes, insurance, utilities, common area maintenance and other operating costs and expenses (collectively, “Operating Expense Pass-Throughs”) in connection with the ownership, operation, maintenance and management of the Subject Property. Seller and Purchaser shall each receive a debit or credit, as the case may be, for the difference between the Tenant’s collected account balance for Operating Expense Pass-Throughs and the amount of Operating Expense Pass-Throughs due to or from Tenant as of the Closing Date. Operating Expense Pass-Throughs for Seller’s period of ownership shall be reasonably estimated by the parties if final bills are not available. If Seller was overpaid by any Tenant for the period with respect to any such charges prior to Closing, Seller shall remit to Purchaser such estimated overpayment at Closing. If Seller was underpaid by any Tenant for the period with respect to any such charges prior to Closing, Seller shall receive a credit at Closing for the amount of such estimated underpayment. Any item in this Section 9(g) that is paid directly by any Tenant pursuant to its Lease shall not be prorated between the parties, and Purchaser shall look to the Tenant to pay such items. Seller and Purchaser agree to cooperate and use their good faith and diligent efforts to do a true-up and make any necessary adjustments to the proration of the Operating Expense Pass-Throughs within ninety (90) days after the calendar year end following Closing.

          (h) Security Deposits. Purchaser shall receive a credit against the Purchase Price in an amount equal to the sum of all unapplied cash security deposits in Seller’s possession plus, if accrued interest on such security deposits must be reimbursed to any Tenant that paid a security deposit, all interest accrued on such security deposits.

          (i) Recording Costs. Seller and Purchaser shall each pay one-half of the cost of recording the Deed and all other recording costs, except Purchaser shall pay any and all recording costs in connection with any loan documentation or mortgages recorded by Purchaser and/or Purchaser’s lender, if any.

          (j) Leasing Commissions for Renewals, Expansions and Options. Purchaser shall be responsible to pay any leasing commissions due with respect to the renewal, expansion or exercise of options on any Lease, as set forth on Exhibit B-1.

          (k) Other Costs. All other costs shall be allocated in accordance with the customs prevailing in similar transactions in the respective metropolitan areas where the Subject Property is located.

Except as otherwise expressly provided in this Agreement, all prorations provided for herein shall be final.

     10. Default/Remedies. IN THE EVENT OF A BREACH OR DEFAULT BY SELLER IN CLOSING THE TRANSACTION CONTEMPLATED BY THIS AGREEMENT, PURCHASER, AS ITS SOLE AND EXCLUSIVE REMEDY, SHALL HAVE THE RIGHT EITHER (I) TO TERMINATE THIS AGREEMENT AND RECEIVE A RETURN OF THE EARNEST MONEY AND SELLER SHALL REIMBURSE PURCHASER FOR ITS REASONABLE OUT OF POCKET COSTS UP TO A MAXIMUM AMOUNT OF $37,500.00 ASSOCIATED WITH THE NEGOTIATION AND PREPARATION OF THIS AGREEMENT AND ITS EXAMINATION OF THE PROPERTY, INCLUDING WITHOUT LIMITATION, THE FEES AND DISBURSEMENTS OF ITS COUNSEL, ADVISERS, AND AGENTS, OR (II) TO ENFORCE SPECIFIC PERFORMANCE OF THIS AGREEMENT, PROVIDED THAT ANY ACTION FOR SPECIFIC PERFORMANCE BE COMMENCED WITHIN NINETY (90) DAYS OF THE SCHEDULED CLOSING DATE (OR SUCH LONGER PERIOD AS MAY BE REQUIRED BY LAW), AS THE SAME MAY HAVE BEEN EXTENDED PURSUANT TO THE PROVISIONS HEREOF. EXCEPT FOR THE SURVIVING INDEMNITY OBLIGATIONS, WHICH SHALL SURVIVE TERMINATION OF THE AGREEMENT, IN THE EVENT OF A BREACH OR DEFAULT BY PURCHASER IN CLOSING THE TRANSACTION CONTEMPLATED BY THIS AGREEMENT, SELLER, AS ITS SOLE AND EXCLUSIVE REMEDY, SHALL HAVE THE RIGHT TO TERMINATE THIS AGREEMENT AND RECEIVE THE EARNEST MONEY AS LIQUIDATED DAMAGES, IT BEING AGREED BY SELLER AND PURCHASER THAT THE DAMAGES TO SELLER IN CASE OF DEFAULT BY PURCHASER MAY BE IMPOSSIBLE TO ASCERTAIN AND THAT THE EARNEST MONEY CONSTITUTES A FAIR AND REASONABLE AMOUNT OF DAMAGES IN THE CIRCUMSTANCES AND IS NOT A PENALTY. NOTHING HEREIN CONTAINED SHALL LIMIT THE RIGHTS OR OBLIGATIONS OF THE PARTIES WITH RESPECT TO A DEFAULT UNDER THIS AGREEMENT OCCURRING AFTER THE CLOSING DATE, AND IN SUCH CASE THE PARTIES SHALL HAVE ALL RIGHTS AND REMEDIES AVAILABLE AT LAW, IN EQUITY OR OTHERWISE INCLUDING, WITHOUT LIMITATION, THE RIGHT TO SPECIFIC PERFORMANCE, SUBJECT TO THE CONDITIONS AND LIMITATIONS HEREIN SET FORTH, INCLUDING, WITHOUT LIMITATION, THE PROVISIONS OF SECTION 6(b) HEREOF. NOTWITHSTANDING ANYTHING HEREIN TO THE CONTRARY, NEITHER PARTY SHALL BE ENTITLED TO RECEIVE SPECIAL, CONSEQUENTIAL, INCIDENTAL OR PUNITIVE DAMAGES UNDER THIS AGREEMENT OR OTHER DOCUMENTS DELIVERED IN CONNECTION HEREWITH.

     11. Damage. If, prior to the Closing Date, all or any part of the Improvements are substantially damaged by fire or other casualty, Seller shall promptly give notice to Purchaser of such

fact. Thereafter, at Purchaser’s option (to be exercised by Purchaser’s written notice to Seller given within thirty (30) days after Seller’s initial notice to Purchaser), this Agreement shall terminate with respect to the Subject Property. In the event of any such termination of this Agreement, the Earnest Money shall be returned to Purchaser and thereafter neither party will have any further obligations under this Agreement (other than the Surviving Indemnity Obligations, which obligations shall survive any such termination), that Purchaser shall, at the request of Seller, execute any document reasonably requested by Seller to evidence such termination including, without limitation, a quit claim deed. If Purchaser fails to elect to terminate this Agreement (in the manner provided in this Section 11) despite such damage, or if the Improvements are damaged but not substantially, Seller shall promptly commence to repair such damage or destruction and to return the damaged Improvements to substantially their condition prior to such damage. If such damage shall be completely repaired prior to the Closing Date, then there shall be no reduction in the Purchase Price, and Seller shall retain the proceeds of all insurance related to such damage. If such damage shall not be completely repaired prior to the Closing Date, but Seller is diligently proceeding to repair, then Seller shall complete the repair after the Closing Date and shall be entitled to receive the proceeds of all insurance related to such damage; provided, however, that Purchaser shall have the right to delay the Closing Date until repair is completed. For purposes of this Section 11, the phrase “substantially damaged” means damage that gives rise to the ability of the Tenant(s) leasing at least fifty percent (50%) of the rentable square feet in the Subject Property (in the aggregate) to terminate such Tenants’ Lease(s) pursuant to the terms and conditions of such Lease(s) and such Tenant(s) actually terminate such Lease(s).

     12. Condemnation. If, prior to the Closing Date, eminent domain proceedings are commenced against all or any substantial part of the Subject Property, Seller shall immediately give notice to Purchaser of such fact and, at Purchaser’s option (to be exercised within fifteen (15) days after Seller’s notice), this Agreement shall terminate with respect to the Subject Property. In the event of any such termination, the Earnest Money shall be returned to Purchaser and thereafter neither party will have further obligations under this Agreement (other than the Surviving Indemnity Obligations, which obligations shall survive any such termination), except that Purchaser shall, at the request of Seller, execute any document reasonably requested by Seller to evidence such termination including, without limitation, a quit claim deed. If Purchaser fails to elect to terminate this Agreement in the manner provided in this Section 12, then there shall be no reduction in the Purchase Price, and Seller shall assign to Purchaser at the Closing Date all of Seller’s right, title and interest in and to any award made or to be made in the condemnation proceedings. Prior to the Closing Date, Seller shall not designate counsel, appear in, or otherwise act with respect to the condemnation proceedings without Purchaser’s prior written consent, which consent shall not be unreasonably withheld or delayed; provided, however, that if any action is necessary with respect to such proceeding to avoid any forfeiture or material prejudice, Seller shall be entitled to take such action as and to the extent necessary without obtaining Purchaser’s prior written consent. For purposes of this Section, the words “substantial part” means that the portion of the Subject Property to be so taken gives rise to the ability of the Tenant(s) leasing at least fifty percent (50%) of the rentable square feet in the Subject Property (in the aggregate) to terminate such Tenants’ Lease(s) pursuant to the terms and conditions of such Lease(s) and such Tenant(s) actually terminate such Lease(s).

     13. Broker’s Commissions. Seller represents to Purchaser that insofar as Seller knows, no third party broker or finder has been engaged or consulted by Seller or is entitled to compensation or commission in connection herewith, other than Secured Capital Corporation (“Seller’s Broker”). Seller shall be responsible to pay commissions due to Seller’s Broker in connection with the sale contemplated by this Agreement. Seller shall defend, indemnify and hold harmless Purchaser from and against any and all claims of brokers, finders of any like third party claiming any right to commission or compensation by or through acts of Seller in connection herewith. Purchaser represents and warrants to Seller that insofar as Purchaser knows, no third party broker or finder has been engaged or consulted by Purchaser or is entitled to compensation or commission in connection herewith, other than Grubb and Ellis.

Purchaser shall defend, indemnify and hold harmless Seller from and against any and all claims of brokers, finders or any like party claiming any right to commission or compensation by or through acts of Purchaser in connection herewith. The indemnity obligations hereunder shall include all damages, losses, risks, liabilities, and expenses (including reasonable attorneys’ fees and costs) arising from and related to matters being indemnified hereunder, and shall survive Closing and execution and delivery of the Deed; provided, however, the total liability of Seller with respect to the foregoing indemnity obligation shall be subject to the conditions and limitations set forth in Section 6(d) hereof.

     14. Environmental Disclosure. Certain federal laws and state laws, including without limitation the Comprehensive Environmental Response Compensation & Liability Act of 1980 (CERCLA), 42 U.S.C. Section 9601 et seq., require sellers of certain real estate to disclose the existence of hazardous substances located on or beneath the property being transferred. To satisfy such obligations under any and all applicable laws, ordinance, rules and regulations, Seller hereby discloses that the Real Property contains or contained such hazardous materials (if any) as described in the environmental reports listed on Exhibit L attached hereto and made a part hereof (the “Reports”). Seller shall deliver the Reports to Purchaser within three (3) business days following the execution of this Agreement, and Purchaser shall acknowledge receipt of the Reports. Purchaser acknowledges and agrees that the Reports are provided by Seller for informational purposes only and that Seller makes no representations or warranties as to the accuracy or completeness of the Reports. Purchaser will conduct its own investigations and studies of the Subject Property as it deems necessary or appropriate in order to determine the presence or absence of hazardous materials on or within the Subject Property. Purchaser hereby (a) agrees that Purchaser is relying solely on its own investigation, if any, of the Subject Property covering the effect of any hazardous materials that may be on about or within the Subject Property, whether disclosed by such investigations or not (collectively, the “Hazardous Materials Effect”) and (b) assumes the risk of any and all liabilities, claims, demands, suits, judgments, losses, damages, expenses (including, without limitation, attorney’s fees) and other obligations arising out of or incurred in connection with the Hazardous Materials Effect, if any.

     15. Assignment. Purchaser may not assign its rights under this Agreement without the prior written consent of Seller; provided, however, Purchaser may assign its rights under this Agreement to (i) Columbia Equity Trust, Inc. (the “REIT”), (ii) Columbia Equity, L.P. (the “OP”), or (iii) any trust, corporation, partnership or limited liability company controlling, controlled by or under common control with Purchaser, the REIT or the OP. For purposes hereof, “control” shall mean ownership (directly or indirectly) of 51% or more of the voting or comparable ownership interest of any such trust, corporation, partnership or limited liability company. Any assignment shall be subject to all the provisions, terms, covenants and conditions of this Agreement and the assignor shall, in any event, continue to be and remain liable under this Agreement, as it may be amended from time to time, as a principal and not as a surety, without notice to such assignor. Any such assignment and assumption shall be evidenced by a written agreement in form and substance reasonably acceptable to Seller.

     16. Non-Recourse to Partners of Partnership. Seller and Purchaser agree that the neither the general partner nor any limited partner of Seller shall be personally liable for any obligations under this Agreement or any document executed in connection herewith.

     17. Catastrophic Environmental Event. If, after the Contingency Date and prior to the Closing Date, any Catastrophic Environmental Event (as defined below) occurs with respect to the Subject Property, Seller shall give notice to Purchaser of such fact promptly after Seller becomes aware of such occurrence. Thereafter, at Purchaser’s option (to be exercised by Purchaser’s written notice to Seller given within thirty (30) days after Seller’s initial notice to Purchaser), this Agreement shall terminate.

In the event of any such termination of this Agreement, neither party will have any further obligations under this Agreement (other than the Surviving Indemnity Obligations, which obligations shall survive any such termination), except that Purchaser shall, at the request of Seller, execute any document reasonably requested by Seller to evidence such termination including, without limitation, a quit claim deed. If Purchaser fails to elect to terminate this Agreement in the manner provided in this Section 17, then there shall be no reduction in the Purchase Price, and the parties shall proceed to Closing upon the terms and conditions of this Agreement. For purposes of this Section 17, the phrase “Catastrophic Environmental Event” means an adverse environmental event on the Subject Property resulting in a violation of applicable environmental laws requiring cleanup. Notwithstanding the foregoing, an adverse environmental event shall not be a Catastrophic Environmental Event if a “no further action” letter addressed to Seller or a “no association” letter addressed to Purchaser, or their equivalents, has been received from the relevant governmental authorities prior to Closing.

     18. Notices. Any notice or other communication in connection with this Agreement shall be in writing and shall be sent by nationally recognized overnight courier guaranteed next business day delivery, by telecopy or facsimile transmission (provided that such notice sent by facsimile is also sent via nationally recognized overnight courier for guaranteed next business day delivery), or by personal delivery, properly addressed as follows:
