Fairfax Interest, which shall be each delivered at the Closing to Buyer free and clear of all Liens, is Three Hundred Forty Seven Million and 00/100 Dollars ($347,000,000.00), which shall be payable at the Closing, as hereinafter defined, after adjustment for prorations, credits and cost allocations provided for in this Contract, in lawful currency of the United States of America by deposit with the Title Company (hereinafter defined) of immediately available funds to an account designated by Seller prior to the Closing.

Buyer shall receive a credit against the Purchase Price in amount equal to the outstanding principal balances on the Closing Date of the MetLife Loans and of the Other First Loan (as hereinafter defined), which such Other First Loan shall be paid in full by Buyer immediately following Closing, subject to the terms and conditions of Section 2 below and Seller’s obligation and covenant to obtain a pay off letter from each of the holders of the Other First Loan, at its sole cost and expense, in form and substance satisfactory to Buyer and the Title Company in their reasonable discretion.

The Deposit shall be held and disbursed as provided herein and, at the Closing, the Deposit shall be applied in full toward the Purchase Price.

Notwithstanding anything herein to the contrary, other than the Permitted Liabilities (as described herein) and then only to the extent contemplated to survive hereunder, Buyer shall not assume, or otherwise be responsible for, any liabilities of Seller, the Company, the LLCs or any of their affiliates, arising out of occurrences on or before the Closing including without limitation, any liabilities or obligations related to the Excluded Assets, Excluded Contracts, and the 4250 N. Fairfax Loan, or any liabilities of Seller arising out of occurrences after the Closing (the “Excluded Liabilities”).

2. Lender Consents: The parties acknowledge that the assignment of the Shares to Buyer (and related transactions contemplated hereby) requires only the consent

5

Attached hereto as Exhibit T is a copy of the consent of MetLife to the sale of the Shares (and related transactions contemplated hereby). Any and all fees or costs in the nature of assumption, transfer or consent fees (“Consent Fee” and including any and all administrative or processing fees and other related costs, collectively, “Consent Costs”) imposed by MetLife in connection with obtaining the MetLife Consent (as herein defined) and except as otherwise provided herein, all other costs including, without limitation, title, escrow, other searches and recording costs and expenses, counsel fees (other than Buyer’s counsel) in connection therewith shall be borne by Seller.

The Other First Loan shall be repaid immediately following the Closing by Buyer (subject to Buyer receiving the credit against the Purchase Price and subject to the other provisions set forth below in this paragraph).

(d) The Closing shall not be deemed to be completed until all documents and payments as aforesaid have been properly delivered (and recorded if and where appropriate) to the satisfaction of all parties. However, upon Closing, the parties shall be deemed to have satisfied all of their obligations hereunder, except for the obligations, if any, expressly stated to survive the Closing Date (collectively, the “Surviving Obligations”).

5. Certain Disclosure Matters: (a) The 400 Virginia Property has the benefit of a document entitled Underpinning Agreement dated as of September 23, 1983, wherein an abutting land owner allowed its property to be used for the underpinning of the improvements constructed on the Property. A copy of the Underpinning Agreement is attached hereto as Exhibit I-1. On January 15, 2001, the then owner of the adjoining property issued an estoppel certificate confirming that there were no defaults by the owner of the Property with respect to the Underpinning Agreement. A copy of the estoppel certificate is attached hereto as Exhibit I-2. Seller represents and warrants that Seller is unaware of any default under the Underpinning Agreement and that Seller has not received any notice of default under the Underpinning Agreement and Seller shall provide an affidavit to that effect for the benefit of the Title Company and cooperate with Buyer’s effort to pursue an updated and revised estoppel in form and substance satisfactory to Buyer prior to the expiration of the Due Diligence Period, but (unless otherwise agreed by Seller in connection with Buyer’s additional investigation) obtaining the same shall not be a condition of Buyer’s obligations hereunder.

(b) At the time 4250 N. Fairfax acquired the 4250 N. Fairfax Property, Seller was made aware of an allegation by Cosi, Inc., a tenant at said Property, that Qwest Communications Corporation (the “Former Owner”) had violated an exclusive use provision contained in its lease (the “Cosi Allegation”). The Former Owner provided certain assurances to 4250 N. Fairfax in that regard. A true, correct and complete copy of

14

all of the relevant sections of the contract between the Former Owner and Seller, together with a copy of the estoppel letter from Cosi, Inc., (together, with its affiliates, successors and assigns, “Cosi”) is attached hereto as Exhibits S-1 and S-2 respectively (collectively, the “Cosi Allegation Documents”) and a true and complete copy of said contract has been delivered to Buyer. Subject to the terms in this paragraph below, Buyer hereby agrees that if a Tenant Estoppel from Cosi in accordance with Article 7 hereof is delivered which otherwise complies with the terms of an acceptable Tenant Estoppel (from the named tenant on the Lease), but similarly raises, without additional objections or allegations, said violation as an alleged default, Buyer shall nevertheless accept said Tenant Estoppel as an acceptable Tenant Estoppel. Seller represents and warrants that other than the Cosi Allegation Documents, Seller has not received any other notice, claim, complaint or other information from Cosi or the Former Owner evidencing, supporting, restating, challenging, enhancing, explaining or modifying the Cosi Allegation. Seller further covenants that Seller shall timely and promptly provide to Buyer any information, notices, or additional claims with respect to the Cosi Allegation or Cosi Allegation Documents and for a period of one (1) year(if a claim is made during that period until settled or otherwise resolved), Seller shall protect and hold Buyer, and Buyer Responsible Party harmless from and against (and cause the Former Owner, as applicable, under the Cosi Allegation Documents to protect and hold Buyer (and the 4250 N. Fairfax Owner) harmless from and against any and all claims, acts, debts, demands, actions, causes of action, suits, sums of money, covenants, contracts, accounts, agreements, promises, representations, restitutions, omissions, variances, losses, damages, obligations, costs, response actions, fees (including, without limitation, attorneys, consultants and experts fees) (collectively, “Claims”) arising out of or resulting or connected with the Cosi Allegation or Cosi Allegation Documents, and to the extent Seller has so satisfied Buyer, Seller shall be entitled to enforce the payment and contribution obligations of the Former Owner, and Buyer shall reasonably cooperate with Seller, in connection therewith. If Cosi, Inc. provides a Tenant Estoppel in accordance with Article 7 that does not raise a Cosi Allegation, Seller’s indemnity under this paragraph shall be of no force or effect. Following such one (1) year period, Buyer shall be entitled to the benefit of the Former Owner’s contribution obligations and Seller, shall pursue its rights against the Former Owner, on behalf of, and at the request of Buyer at no cost to Buyer.

(c) Seller’s representations, warranties, indemnities and covenants in this Section shall survive the Closing.

6. Due Diligence: Seller acknowledges that the Buyer intends to conduct an investigation of the Company, the Property, the Owner LLCs’ Property, the TZO Loan, the TTF Loan, the ESDI Loan, the 1201 MetLife Loan, the 1225 MetLife Loan, and all of the books and records of the Company and the LLCs. Commencing on the date hereof, Buyer, and Buyer’s employees, agents, consultants, advisors, attorneys, accountants, engineers and other representatives (“Buyer’s Representatives”) shall have the right to perform and conduct such examinations and investigations thereof as Buyer may desire, which may include, without limitation, examination of all structural and mechanical aspects of the Property, review of documentation, income and expenses, all Leases and

15

tenant files, records of repairs and capital improvements (excluding only any materials which are not required or desirable for the operation, management or ownership of the Property, Company, or any of the LLCs including without limitation any reporting requirements and which are of a proprietary nature, (such as internal valuation analysis, projections, and other materials constituting the legally privileged and confidential work product of Seller but not if the same relate to related liabilities and obligations being assumed or intended to be assumed by Buyer or which Buyer is otherwise subject), examination of the title to the Property, conducting environmental tests to determine the presence or absence of hazardous waste or materials, asbestos, lead paint, indoor air quality, radon and other similar materials and substances at, in on, under or from the Property, and other environmental conditions at the Property, preparing and reviewing a current as-built survey thereof, and determining the compliance of the Property with all applicable laws, rules, codes and regulations. In connection with such examination, Seller shall deliver and make available (at reasonable times and places) for Buyer’s review all of the books and records of the Company, the LLCs and Owner LLC and the MetLife Loans, the Other First Loan and including without limitation the other items set forth on Schedule 1 attached hereto to the extent not heretofore delivered.

If the expiration of the Due Diligence Period shall fall on Saturday, Sunday or holiday, the Due Diligence Period shall automatically be extended to the next business day. Notwithstanding anything herein to the contrary, nothing herein shall authorize Buyer, nor shall Buyer be permitted to conduct, any subsurface or groundwater environmental testing or other environmental samplings relating to the Property without Seller’s prior written consent, which consent may be withheld or denied in Seller’s sole discretion; provided that lead, radon, indoor air quality and asbestos sampling shall be permitted without Seller’s prior consent and provided further that if Seller unreasonably withholds or denies consent for Phase II testing, then Buyer shall be entitled to terminate the Contract, by written notice to Seller, whereupon the Deposit shall be returned to Buyer, and Seller shall reimburse Buyer for its transaction costs and expenses, including, without limitation, all attorneys’ fees, costs and expenses up to the amount of $150,000, and neither party shall thereafter have further rights or remedies hereunder, other than those expressly stated to survive termination.

The “Due Diligence Period” shall mean the period commencing on the date hereof and ending at 5:00 p.m. (EDST) on November 20, 2003. Notwithstanding anything to the contrary contained in this Contract, Seller acknowledges that Buyer shall have the right in its sole and absolute discretion, either based upon its disapproval of any of the information it receives, for any other reason whatsoever or for no reason, to terminate this Contract on or before expiration of the Due Diligence Period. Except to the extent that Buyer provides written notice to Seller on or prior to the expiration of the Due Diligence Period (as it may be extended as provided herein) that Buyer has elected to proceed to Closing in accordance with, but subject to, the terms hereof, this Contract shall ipso facto terminate and be deemed to have terminated, in which event the Deposit shall be returned to Buyer forthwith and the parties shall thereafter have no further obligations hereunder except those expressly stated to survive such termination. The failure of Buyer to provide any notice at all to Seller on or prior to expiration of the Due Diligence Period shall constitute and be deemed to be the election of Buyer to terminate this Contract in accordance with its right to do so under this Article 6.

16

Subject to the limitations set forth above, Seller and the Owner LLCs shall, upon reasonable notice and at reasonable times, make the Property available to Buyer and Buyer Representatives for such inspections and tests as Buyer deems appropriate, including for Buyer’s engineering inspection(s), environmental compliance inspections, site evaluations, and such other inspections and tests as Buyer deems appropriate, at Buyer’s sole cost and expense. Seller shall have the right to have a representative present during all or any of Buyer’s such inspections and tests. Buyer, accompanied by a representative of Seller or, at Seller’s election, an employee of the Property Manager, may interview tenants, such interviews to be scheduled by Seller promptly at Buyer’s request; provided that Seller or such representative shall make themselves reasonably and promptly available if such election is made.

Without limiting the foregoing, Buyer shall have the right to contact and interview The John Akridge Company including without limitation Brian A. Cass, an Officer of The John Akridge Company or at Buyer’s election any other officer, director or employee thereof, or any other member (collectively, the “Akridge Representative”); provided that reasonably adequate prior notice thereof shall be given by Buyer to Seller or to Seller’s representative and, if requested by Seller, Buyer shall allow Seller or a representative of Seller to arrange and be present (in person or by phone) at any such meeting but only to the extent involving the discussion of the Akridge Representative as to the interests of the non-Seller affiliates as members of the Eye Street Owner. Without limiting the foregoing, Seller shall cooperate with Buyer promptly and in good faith to set up any meetings with the Akridge Representative if requested by Buyer. Subject to the forgoing, Buyer shall not in any way be prohibited from or limited in discussing any issues, matters or concerns relating to the LLC Property and/or the ownership and debt structure thereof, including without limitation, management, leasing, maintenance, construction, financing and/or operation of the Property and/or the structure, management, and/or organization of the Eye Street LLC Owners, Eye Street Equity LLCs, and/or the Eye Street Loan Documents.

Seller and Buyer acknowledge and agree that it is a condition to Buyer’s obligations hereunder as provided in Article 7(a)(viii) hereunder that the Eye Street Documents Amendments (as therein defined) conforming to the terms set forth on Exhibit V attached hereto and made a part hereof and otherwise conforming to the provisions of said Article 7(a)(viii) are duly executed and delivered. It shall be a condition of Closing that the non-Seller members of the Eye Street LLC Owners (the “Akridge Members”) execute and deliver the Eye Street Document Amendments, in the forms attached or as approved by Buyer, in its sole discretion, on or prior to Closing or Buyer may elect to terminate this Contract on the same terms as this Article 6.

Buyer hereby agrees to indemnify and hold Seller and the LLCs harmless from and against any and all loss, cost or damage to the Property (but not any loss, cost, expense or damages or diminution in value arising from or related to any condition

17

discovered by Buyer or by any act of Seller, the Company, or any LLC) resulting directly from actions taken by Buyer or its agents, engineers or consultants. Prior to its entry on the Property, Buyer shall provide to Seller certificates of liability insurance insuring Buyer and Seller and the LLCs in an amount not less than Two Million Dollars ($2,000,000.00). Buyer shall promptly repair all damage to the Property resulting directly from any such inspections or tests by Buyer and shall to the extent reasonably practicable restore the Property to substantially the same condition existing immediately prior to such inspections and tests, but only to the extent such change in condition was caused by such inspections and tests, reasonable wear and tear excepted. In the event Buyer discovers any matter during the course of its investigations and tests which may be reportable under applicable law, Buyer acknowledges and agrees that it shall not undertake any such reporting, except to the extent Buyer is legally mandated to do so, but shall notify Seller promptly of any such discovery. In performing any such inspections or tests, Buyer shall not unreasonably interfere with the activities on the Property of any tenant under the Leases. The indemnification, repair and restoration obligations of Buyer under this paragraph shall survive the termination of this Contract only with respect to the period prior to the termination for a period of one (1) year after such termination.

Seller shall deliver to Buyer an existing ALTA survey of each Property and Buyer, at its option, may obtain each of the following at its own cost and expense: (i) an updated current ALTA Survey of the Property (the “Survey”) certified to the Buyer and the Title Company; and (ii) a title insurance commitment (or an endorsement to the existing owner’s and lender’s title policies attached hereto as Exhibits J-1 - J-4 and Exhibits K-1 - K-3 respectively issued by Commonwealth Land Title Insurance Company or Chicago Title Insurance Company, as Buyer, in its sole discretion, may elect, (the “Title Company”) (the “Title Commitment”) containing such endorsements, affirmative coverages and reinsurance or co-insurance agreements as Buyer shall require and specifying the Title Company’s requirements relating to the issuance of such title policy (the “Title Requirements”). Buyer has given Seller notice (“Buyer’s Title Notice”) of Buyer’s disapproval of any of the title exceptions contained in the Title Commitment (or of any matter disclosed on the Survey) specifying those Title Requirements, if any, contained in the Title Commitment which are to be performed by or on behalf of Seller, the Company or the LLCs. Seller, by written notice to Buyer (“Seller’s Title Notice”) has notified Buyer of the Title Requirements and other title objections which Seller agrees to satisfy or cure. Except for Monetary Encumbrances and New Exceptions (as herein defined), which Seller shall be obligated to satisfy and cure whether or not notified by Buyer, if Seller does not agree to cure or satisfy any matters identified in Buyer’s Title Notice, Buyer may terminate this Contract by written notice to Seller given on or before the later of the expiration of the Due Diligence Period or otherwise be deemed to have waived any matter except for Monetary Encumbrances and New Exceptions, which Seller shall be obligated to satisfy and cure, Seller has not agreed to satisfy or cure or use its reasonable efforts to cure or satisfy. If Seller does not respond to Buyer’s Title Notice as provided above, Seller shall be deemed not to have agreed to satisfy or cure the matters set forth therein. Except for Monetary Encumbrances and New Exceptions, which Seller shall be obligated to satisfy and cure, Buyer shall be deemed to have accepted those matters appearing as exceptions in Buyer’s Title Commitment and those matters

18

appearing on the Survey to which Buyer has not objected in Buyer’s Title Notice (or which Buyer is deemed to have waived), and each such matter not so objected to shall be deemed a “Permitted Title Exception”. Buyer shall also have the right to object to, as part of Buyer’s Title Notice, but nothing herein shall obligate Seller to deliver the Property to Buyer at the Closing free and clear of, the encumbrances, restrictions, easements and other matters identified on the existing owner’s title insurance policy of the LLC and lender’s title insurance policy in favor of the Eye Street Lending LLCs identified on Exhibits J-1 - J-4 and Exhibits K-1 - K-3 attached hereto and incorporated herein by reference other than as to Monetary Encumbrances and New Exceptions, which Monetary Encumbrances and/or New Exceptions, Seller shall be obligated to satisfy or cure (and Buyer may, at its option use the Seller’s proceeds at Closing to satisfy); provided further that, as an alternative to the satisfaction or cure of a Monetary Encumbrance by payment, Seller shall have, at its option, the right to (i) bond over any such encumbrance or (ii) take such other action in order to have the encumbrance removed as an exception to title, which in either the case of (i) or (ii) shall be in a manner as may be reasonably acceptable to Buyer and the Title Company.

In the event this Contract is terminated under this Section, all obligations, liabilities and rights of the parties under this Contract shall terminate (other than those expressly stated to survive such termination), and the Deposit shall be returned to Buyer. If Seller has elected to cure any matter or to satisfy any Title Requirement or as to a Monetary Encumbrance or New Exception is required to satisfy, remove or cure any matter, such matter shall be cured, removed or satisfied by Seller at or prior to the Closing Date. The failure of Seller to satisfy, remove or cure any such matter to Buyer’s reasonable satisfaction shall constitute a default by Seller hereunder.

(ix) Qwest Communications Corporation confirms in writing in form and substance acceptable to Buyer, in its reasonable discretion, that Quest’s right of first offer under its Lease is of no further force and effect.

If any condition set forth herein is not fully satisfied on or before the Closing Date, Seller may elect to attempt to satisfy or cure any such condition, and if Seller so elects, Seller shall have a period not exceeding thirty (30) days after the Closing Date to satisfy such condition, and the Closing Date shall be extended accordingly; provided that if Seller extends the Closing Date to attempt to satisfy or cure any such condition as aforesaid, then it shall be a condition of Closing (herein, the “MAC Condition”) during such extension, that there shall not have occurred and be continuing at Closing any material, adverse change in the physical, financial or legal conditions of the LLC Owner or the Property, from the conditions thereof as accepted by Buyer as of the expiration of the Due Diligence Period, ordinary and reasonable wear and tear excepted with respect to the physical condition of the Property and casualties and condemnation governed by Article 10, and provided that a downgrade of more than one level in rating of any of the following Major Tenants: Lockheed Martin Corporation, Titan Corporation, Qwest Communications Corporation and NCS Pearson shall be deemed a material adverse change.

(b) In the event any condition precedent to Closing is unsatisfied because of a breach by Seller (or the Company, or any LLC) of its obligations or representations and warranties set forth or contemplated in this Contract (or any representations and

26

warranties were untrue when made) Seller shall be deemed to be in default hereunder in which event the foregoing thirty (30) day cure period shall not be applicable and the provisions of Article 8 for a Seller default shall apply.

8. Default: (a) If on the Closing Date, Seller is in default hereunder, has breached a representation or has failed to perform any of its obligations or covenants hereunder (not otherwise waived by Buyer) in each case in any material respect, Buyer’s sole and exclusive remedy shall be the right to exercise either one of the following:

(i) Buyer shall have the right to terminate this Contract by notice to Seller, in which event the Deposit shall be paid to Buyer, and thereafter, and Seller shall reimburse Buyer for its out of pocket expenses not to exceed $750,000, and thereafter, all rights and obligations of the parties under this Contract shall terminate, except for those expressly stated to survive such termination; or

(ii) Buyer may specifically enforce Seller’s obligations hereunder; provided that if specific enforcement is unavailable, including, without limitation, as a result of or in connection with a breach of Section 13(f) or Section 11 or other willful or intentional action of Seller taken in bad faith, then, in addition to a refund of the Deposit and any other rights of Buyer hereunder, Buyer shall also be entitled to direct (but not consequential) damages in an amount not to exceed $10,000,000.

(b) In the event of a material default by Buyer hereunder after the expiration of the Due Diligence Period, it would be extremely impracticable and difficult to estimate the damage and harm which Seller would suffer, and because a reasonable estimate of the total net detriment that Seller would suffer in the event of Buyer’s failure to duly complete the acquisition hereunder is the amount of the Deposit, Seller shall be entitled to receive and retain the Deposit as and for Seller’s sole and exclusive remedy arising from Buyer’s failure to complete the acquisition in accordance with the terms hereof, and Seller shall have no further recourse or remedy at law or in equity for any breach by Buyer hereunder.

Notwithstanding anything herein to the contrary each party shall also have the right to enforce the specific performance of any indemnity or obligation of the other party which expressly survives the termination and to sue the other party for damages incurred as a result of such other party’s failure to perform its Surviving Obligations; provided that Seller agrees to apply the Deposit if entitled to retain the Deposit against damages for any such surviving obligations of Buyer.

Fairfax Property or 400 Virginia Property, individually, and which may legally be restored or repaired to their former condition, does not result in a termination of any Lease with any Major Tenant and which casualty is fully insured under Seller’s insurance (subject only to a deductible which is credited to Buyer) and for which rent loss insurance is still available to the applicable Owner LLC after Closing in each case, without a change of control exclusion, then, Buyer shall (unless such damage has been repaired in a good and workmanlike manner prior to Closing as approved by Buyer) accept title to the Property in its destroyed or damaged condition. Buyer shall pay the full Purchase Price without reduction (except as set forth below), and Seller shall pay over or assign to Buyer all rights to any proceeds of insurance payable (or paid) with respect to such destruction or damage, together with amounts equal to any deductibles thereunder (less amounts actually and reasonably expended by Seller or the Owner LLC (as approved by Buyer) in repairing the damage prior to the Closing Date) and Buyer shall have a credit against the Purchase Price in the amount of any deductible.

28

(d) If prior to the Closing Date, all or part of the Property is taken by condemnation, eminent domain or by agreement in lieu thereof, or any proceeding to acquire, take or condemn all or part of the Property is threatened or commenced, Buyer may either terminate this Contract (in which event Buyer shall be entitled to a return of the Deposit) or purchase the Shares and the 4250 N. Fairfax Interest in accordance with the terms hereof, without reduction in the Purchase Price (except as set forth below). If the Seller, the Company or any LLC has received payments from the condemning authority and if Buyer elects to purchase the Shares and the 4250 N.

Seller shall cause 1201 Owner and 1225 Owner to use any cash balances in excess of the amount so designated by Buyer to pay accrued interest on the 1201 Second Loan, the 1201 Third Loan and the 1225 Second Loan, as applicable, and TZO, 1215 ESDI and TTF shall distribute any such amount and any other cash to Seller, all on or before the Closing Date.

If the net of the aforesaid prorations made as of the Closing is a debit to Seller, then such debit shall be credited against the Purchase Price. If the net of the aforesaid prorations is a credit to Seller, then the Buyer shall pay such net credit amount to Seller at Closing. Any post-Closing adjustment shall be considered an increase or decrease to the Purchase Price and shall be paid in cash between Seller and Buyer].

Notwithstanding any other provision of this Contract to the contrary, including, without limitation, the representation in Section 12(a)(ii) to the extent affecting the same, the Buyer and Seller shall share 75% to Seller and 25% to Buyer of all sales, use, privilege, transfer, documentary, gains, economic interest transfer, stamp, duties, recording and similar Taxes and fees (including any interest, penalties or additions thereon) imposed upon any party hereto, the Company or any Subsidiary in connection with the transfer of the Shares (and the consequences thereof upon the direct or indirect ownership of the Company and the Subsidiaries) and the 4250 N. Fairfax Interest contemplated by this Agreement, exclusive of any transfers pursuant to Section 13(k) (collectively, the “Transfer Taxes”), and any expense incurred to procure any stock transfer stamps required by any Transfer Tax, subject, however, to Seller’s indemnity to Buyer set forth in Article 16(c)(i).

(e) Property Taxes. Following Closing, Buyer shall have the right to control the progress of and to make all decisions with respect to any real property and personal property taxes for the Property due and payable during all real estate and property tax fiscal years in which the Closing occurs and all prior tax years. Real estate and personal property tax refunds and credits received after Closing, with respect to the Property, shall be applied in the following order of priority: first, to pay the costs and expenses (including, without limitation, reasonable attorneys’ fees, expenses and disbursements) incurred in connection with obtaining such tax refund or credit; second, to pay any amount due to any past or present tenant of the Property as a result of such refund or credit to the extent required pursuant to the terms of the Leases; and third, (i) to Seller with respect to all tax years prior to Closing and (ii) with respect to the tax year in which the Closing occurs, to be allocated in the same manner as the real estate taxes have been apportioned under this Contract at Closing. Buyer shall cooperate and cause the respective Owner LLC to cooperate with Seller in prosecuting such appeals. The provisions of this paragraph shall survive Closing indefinitely.

(f) Filing and Preparing Tax Returns; Assistance and Cooperation

(i) Seller shall prepare or cause to be prepared, at the cost and expense of Seller, on a timely basis (including any automatically available extensions), Tax Returns for the Company and the Subsidiaries (including the applicable 1099’s, K-1’s or similar schedules and reports which are part of or derived from any such Tax Returns) for federal and state income, unincorporated business taxable income or any similar type of net income tax applicable to any said entity for all such Tax Returns which are due prior to or for taxable or other relevant periods ending before January 1, 2004, including, without limitation, all such items which are required to be filed by, or with respect to, the Company or any of the Subsidiaries for any taxable year or other taxable period beginning before the Closing Date and ending after the Closing Date (each such period being a “Straddle Period”, and collectively, the “Straddle Periods”). Buyer shall prepare or cause to be prepared, at the cost and expense of Buyer, on a timely basis (including extensions), all federal and state Tax Returns of the Company and the Subsidiaries for all Tax Returns for any Straddle Period other than those to be prepared by Seller pursuant to the immediately preceding sentence. All such Tax Returns shall in all events, be prepared in a manner consistent with the prior Tax Returns as to all continuing elections, characterizations and other matters and, to the extent applicable, the structure and intent of the relevant underlying documents and this Contract and otherwise in accordance with Applicable Law. In addition, the Company shall cause a timely election under Treasury Regulation 1.337(d)-7(c) with respect to the deemed liquidation of 2001 M Street Mortgage Holdings, Inc.

50

Except as provided in the immediately following paragraph, all such Tax Returns shall be provided to the other party at least forty-five (45) days prior to the date any such Tax Return is due (including any automatically available extensions), which other party shall have thirty (30) days after receipt of each Tax Return to review such Tax Return and comment thereon.

As to the 1099’s for the Company for the taxable period which ends on December 31, 2003, Seller shall cause a pro-forma federal income tax return for the Company to be delivered to Buyer on or before December 31, 2003, and the Buyer shall have 10 days after receipt of such pro-forma return to review and comment on such pro-forma return, the intent of such preparation and review being solely to establish the Company’s “real estate investment trust taxable income and earnings and profits” under the Code for the 2003 taxable year so as to enable 1099s for the Company to be timely prepared and sent. The preparation and review, and, if necessary, the resolution of any disagreements as to the Company’s “real estate investment trust taxable income and earnings and profits” pursuant to this paragraph shall be in accordance with the standards set forth elsewhere in this Section 14(f)(i) and in accordance with the procedures of the second immediately following paragraph (other than the first sentence thereof). After the determination of the Company’s “real estate investment trust taxable income and earnings and profits” under the Code for the 2003 taxable year pursuant to the preceding provisions of this paragraph, Seller shall not make a material change in such amount in the preparation of the final federal income tax Tax Return for the Company’s 2003 taxable year without the consent of the Buyer, except for omissions or other changes due to information which Seller was not reasonably aware of, or should have been reasonably aware of, at the time of the preparation of the pro-forma tax return.

Each party hereto shall make available, or cause to be made available, to the other party all the relevant and necessary books and records to enable such party to prepare or review, as the case may be, all such Tax Returns subject to the standards of the preceding provisions and otherwise consistent with Section 14(f)(iii) below and the other applicable provisions of this Contract and subject to the immediately following paragraph.

If Buyer or Seller, as applicable, objects to the treatment of any item on any such Tax Return for any Straddle Period or to any amount owed by Seller or Buyer, as applicable (whether owed by Seller to a Governmental Entity or by Seller to Buyer or vice-versa pursuant to any provision of this Contract) with respect to any Taxes, the objecting party shall, within said thirty (30) days after delivery of such Tax Return, notify the other party in writing that the first party so objects, specifying with particularity any such item and stating the specific factual or legal basis for any such objection. If a notice of objection shall be duly delivered, Seller and Buyer shall negotiate in good faith to resolve their disagreement. If Seller and Buyer have not resolved their disagreement within five (5) Business Days after receipt by the relevant party of such notice of objection, the parties shall refer the matter for resolution to McKee, Nelson LLP (if such law firm is not then representing or has any other business relationship with either party, or is unwilling or unable to accept such matter for resolution, in which case the Arbitrator

51

shall be selected by Seller and Buyer from among practitioners in the real estate investment trust practice in the national office of a “Big Four” accounting firm) (the “Arbitrator”), the decision of which shall be binding on Seller and Buyer. In resolving any such dispute Arbitrator shall first take into account the provisions of the third sentence of the first paragraph of this Section 14(f)(i) and the provisions of Section 14(f)(iii), and then, if such does not, in its opinion, resolve any such issue, then as to any such issue which it cannot resolve pursuant to the above standards, Arbitrator shall then take into account, among other matters it deems appropriate, which position, in Arbitrator’s determination, has the greater weight of authority. The costs, fees and expenses of the Arbitrator shall be borne (1) by Seller if the net resolution (considering such costs) of the disputed items favors Buyer, (2) by Buyer if the net resolution (considering such costs) of the disputed items favors Seller, and (3) otherwise equally by Buyer, on the one hand, and Seller on the other.

Upon the agreement of the parties as to any Tax Return or the resolution of any disagreement as to any Tax Return pursuant to the standards and procedures set forth in this Section 14(f), the responsible party shall promptly complete the final form of Tax Return for filing and, if prepared by Seller, shall provide such form to Buyer, and Buyer shall promptly thereafter sign and file, or cause to be signed and filed, each such completed and final Tax Return.

For any Tax Return for any taxable period which ends prior to the Closing, Seller shall pay to Buyer no less than five (5) days before the applicable due date of such Tax Returns, as an adjustment to Purchase Price, a cash amount equal to all Taxes shown to be due and payable on such Tax Returns to the extent such Taxes exceed the reserve for Tax liability (rather than any reserve for deferred Taxes established to reflect timing differences between book and Tax income) set forth on the face of the Closing Date balance sheet. For any taxes due under any Tax Return for any taxable period which includes the Closing Date, the provisions of Section 16(c)(iii) shall be applicable

(ii) Buyer shall prepare and file or cause to be prepared and filed, at the expense of Buyer on a timely basis (including all automatically available extensions) all Tax Returns of the Company and the Subsidiaries other than those provided for in paragraph 14(f)(i) above. All such Tax Returns shall be prepared in a manner consistent with the prior Tax Returns as to all continuing elections, characterizations and other matters and, to the extent applicable, the structure and intent of the relevant underlying documents and this Contract (except in any instance where there has been a change in Applicable Law or there has been a final determination by the Internal Revenue Service (not appealed) or otherwise a final, binding and unappealed or unappealable determination that any such position or characterization was not correct) and otherwise in accordance with Applicable Law. Subject to Section 16(c) (Tax Indemnities), Buyer shall pay or cause the Company and the Subsidiaries to pay all Taxes shown to be due and payable thereon.

52

(iii) Without limiting the foregoing, after the Closing, Seller and Buyer shall:

(1) assist (and cause their respective affiliates to assist) the other in preparing any Tax Returns which such other person is responsible for preparing and filing in accordance with this Section 14(f);

(2) cooperate fully, as and to the extent reasonably requested by the other party, in connection with the preparation of the Tax Returns pursuant to this Section 14(f) and in connection with any steps or procedures required to be undertaken in compliance with Sections 856 through 860 of the Code and the Treasury Regulations promulgated thereunder;

(3) cooperate fully in preparing for any audits of, or litigation, administrative or other proceedings and any other disputes with taxing authorities regarding, any Tax Returns with respect to the Company or the Subsidiaries or otherwise with respect to Taxes that may be imposed upon or otherwise payable by the Company or any of the Subsidiaries;

(4) make available to the other and to any Governmental Entity as reasonably requested all information, records, and documents of the Company, the Subsidiaries, and their respective affiliates, relating to Taxes;

(5) provide timely notice to the other in writing of any pending or threatened Tax audits or assessments with respect to the Company or the Subsidiaries for taxable periods for which the other may have a liability under this Section 14(f);

(6) furnish each other with copies of all correspondence received from any Governmental Entity in connection with any tax audit or information request with respect to any taxable period for which the other may have a liability under this Contract;

(7) provide the other party with timely notice of the commencement of any audit by any Governmental Entity or of any judicial proceeding involving a Governmental Entity that relates to any liability for Taxes, or any transaction or activity of the Company or any of the Subsidiaries, for which the other may have a liability under this Section 14(f); and

(8) as applicable, prepare and/or file, or caused to be prepared and/or filed, all Tax Returns, all such Tax Returns to be prepared in a manner consistent with the prior Tax Returns as to all continuing elections, characterizations and other matters and, to the extent

53

applicable, the structure and intent of the relevant underlying documents and this Contract (except in any instance where there has been a change in Applicable Law or there has been a final determination by the Internal Revenue Service (not appealed) or otherwise a final, binding and unappealed or unappealable determination that any such position or characterization was not correct) and otherwise in accordance with Applicable Law.

Notwithstanding anything in this clause (iii) to the contrary, all aspects of any audit, litigation or other proceeding with respect to Taxes attributable to a taxable year ending before the Closing shall be controlled by and be the sole responsibility (including all attorney’s fees, court costs and disbursements) of Seller, provided that the Seller shall not enter into any settlement that would increase Taxes in any Straddle or Post Closing taxable year without consultation with Buyer, and, if any such increase would be material, without Buyer’s consent. All aspects of any audit, litigation or other proceeding with respect to Taxes attributable to a taxable year commencing after the Closing shall be controlled by and be the sole responsibility (including attorney’s fees, court costs and disbursements) of Buyer. All aspects of any audit, litigation, or other proceeding with respect to Taxes attributable to a Straddle Period shall be jointly controlled by and be the joint responsibility (including attorney’s fees, court costs and disbursements), based on the respective ownership periods, of Seller and Buyer; provided, further, that as to any matters under this sentence neither party shall (x) settle any such audit, litigation or other proceeding, (y) toll or waive any statute of limitations, or (z) take any other action which would vitiate any of the taxpayer’s substantive or procedural rights with respect to Taxes and any Governmental Entity, relating to the Straddle Period without the prior written consent of the other party, which consent shall not be unreasonably withheld or delayed.

(iv) Buyer covenants and agrees that from and after the Closing it will, or will cause the Company, to take all actions, or forbear from taking actions, as are necessary to ensure that the Company will be classified as, and will not take nor allow the Company or any of the Subsidiaries to take, any action which is inconsistent with the Company’s qualification as, a REIT for the Company’s taxable year that began January 1, 2003 and which ends on or after the Closing (which taxable year may be less than twelve (12) months), which taxable year is herein referred to as the “Company Straddle Taxable Year”, including, without limitation, declaring actual or consent dividends (in addition to the distributions which Seller has covenanted would be made) for taxable year 2003 if and to the extent such are necessary to maintain the status of the Company as a REIT. Furthermore, Buyer covenants and agrees that prior to January 1, 2004, the Company shall not acquire, accept transfer of, nor hold, nor allow any Subsidiary to acquire, accept transfer of, or hold, any assets other than the Property and, as applicable, the interests in the LLCs except in the ordinary course of maintaining, operating and leasing the Property and, as applicable, holding the interests in the LLCs, as all such assets exist immediately prior to Closing. Nothing contained in this Contract or otherwise shall prevent, restrict or otherwise prohibit Buyer from liquidating the Company at any time from and after the Closing, provided that the covenant in the preceding sentences and the other provisions of this Section 14 and any other applicable provisions of the Contract (including, without

54

limitation, the requirement to maintain the qualification of the Company as a REIT pursuant to this Section 14(f)(iv)) are complied with by Buyer. Nothing contained in this Section 14(f) shall require Buyer to take any action to remedy any breach by Seller of its representations and warranties or covenants under this Contract to have maintained the Company’s classification as a REIT prior to the Closing which breach prevents or impairs the ability of the Company from qualifying as a REIT or of Buyer to maintain the qualification of the Company as a REIT and any such breach by Seller shall be fully covered by and Buyer shall be fully covered by Seller’s indemnities hereunder. Buyer agrees that upon becoming aware of any breach described in the immediately preceding sentence it shall make reasonable efforts to notify Seller thereof and agrees to take, or allow Seller to take, such reasonable actions to cure such breach, all at Seller’s cost and expense, provided that any such cure shall not have more than an insubstantial effect on the liability of the Company or any Subsidiary for any Straddle Period or any later taxable period.

(v) Buyer covenants and agrees with Seller that: (a) Buyer will treat the purchase of the Shares contemplated by this Contract for all income tax purposes as a purchase of shares of a corporation, (b) Buyer will not make an election pursuant to Section 338(g) of the Code with respect to the Company, (c) to the extent permitted by Applicable Law, the Company shall designate the maximum amount of the distribution of the Excluded Assets to Seller as a long-term capital gain dividend within the meaning of Section 857(b)(3) of the Code but only to the extent that such designation does not increase the amount of distributions which the Company is required to make arising from its operations and activities during the post-Closing Straddle Period, and (d) subject to Seller’s compliance with Section 13(g), Buyer shall cause the Company to timely and fully pay all accrued and unpaid dividends due to the holders of the Series A Preferred Stock as for the entire 2003 calendar year]..

(vi) Notwithstanding any other provision of this Contract to the contrary, the obligations of Seller and Buyer set forth in this Section 14(f) and in Section 16(c): shall (1) be unconditional and absolute, (2) remain in full force and effect indefinitely and (3) other than as provided in Section 16(c), not be subject to any other indemnification limitations provided in this Contract; provided, that the Tax Representations shall survive the Closing until ninety (90) days following the expiration of the applicable statute of limitations (“Tax Survival Period”) (taking into account all extensions thereof); and provided, further, in the event notice for indemnification under Section 16(c) hereof shall have been given within the Tax Survival Period, the Tax Representation that is the subject of such indemnification claim shall survive until such time as such claim is finally resolved.

(g) With respect to the lease at the 1201 Eye Street Property with the National Park Service as identified on Exhibit C, the tenant and 1201 Owner have not yet entered into a “Supplemental Lease Amendment” (“SLA”) establishing the base dollar amount for real estate tax escalations (the “Base”). If the final agreed upon Base as set forth in the SLA is $1,652,000 or less, there shall be no adjustment to the Purchase Price. For each dollar of the Base which is above $1,652,000, Seller shall pay $6.43 to Buyer as an

55

adjustment to the Purchase Price but in no event shall such payment exceed $450,000. Such payment shall be made within thirty (30) days of delivery by Buyer to Seller of the fully executed SLA. Prior to agreeing to the Base, Buyer shall consult with Seller but the final determination and agreement shall be in the sole discretion of Buyer.

(h) The Tenant Estoppel from NCS Pearson with respect to its lease at the 4250 N. Fairfax Property asserts that said tenant was unable to place two (2) signs on the exterior of the building because of limitations imposed by permits issued by the local governing bodies to Seller’s predecessor in title. The tenant alleges that the failure to obtain the sign could constitute a default by the landlord under said lease. Seller disputes the allegation that if the tenant is unable to obtain said sign, the same would constitute a lease default. Nevertheless, Seller hereby indemnifies, defends and holds Buyer harmless from and against any loss, cost, claim or damage including, without limitation, attorneys fees, arising out of or in connection with the tenant’s claim and/or failure of said tenant to obtain said signage. It is the intention of the tenant to seek a variance or other necessary approval from the public authorities and Buyer hereby agrees that Seller at no cost or expense to Buyer shall be entitled to or at Buyer’s request shall participate in and assist in the seeking of said approval. Buyer further agrees that, if approved by the tenant as a substitute for exterior signage, it will provide interior signage space in appropriate locations. Furthermore, neither Seller nor Buyer shall enter into any settlement agreement with the tenant without the consent of the other, which consent shall not be unreasonably withheld or delayed, provided, however, the consent of Seller shall not be required if the cost of such settlement is $50,000 or less, or if Seller fails to respond within seven (7) business days.

(i) This Article 14 shall survive the Closing.

15. Brokers. Seller represents that, other than Morgan Stanley Realty Incorporated and Holliday Fenoglio, Fowler (together, the “Brokers”), no broker, finder or similar intermediary has acted for or on behalf of, or is entitled to any broker’s, finder’s or similar fee or other commission from, the Seller, the Companies, the LLCs or any affiliate of any of the foregoing in connection with this Contract or the Ancillary Agreements or the transactions contemplated hereby and thereby. Buyer represents that no broker, finder or similar intermediary has acted for or on behalf of, or is entitled to any broker’s, finder’s or similar fee or other commission from, Buyer in connection with this Contract or the Ancillary Agreements or the transactions contemplated hereby and thereby. Each party hereby indemnifies and agrees to save the other harmless from and against any Claims arising from the breach of such representation by the indemnifying party.

(b) Any commission or other fees or expenses due Brokers shall be paid by Seller, and Seller shall obtain and provide to Buyer a receipt and lien release therefore at Closing and Seller hereby indemnifies and saves Buyer harmless from and against any Claim by Brokers in connection with the Property, Shares, the 4250 N. Fairfax Interest or this Contract or the transactions contemplated hereby.

56

(c) The provisions of this Article 15 shall survive the Closing or, if applicable, the termination of this Contract.

16. Continuation and Survival of Representations and Warranties;

(a) Representations Survival.

(i) The representations and warranties set forth in this Contract, as may be modified pursuant this Article 16 or other express provisions of this Contract, are intended to be and shall remain true and correct as of the time of Closing and shall survive the execution and delivery of this Contract and the Closing for a period of one (1) year following Closing except for the representations set forth in Sections 12(a)(ii) [consents], 12(a)(vii) [indebtedness], 12(a)(xii) [insolvency], 12(a)(xiii) [undisclosed liabilities], 12(a)(xiv) [litigation] and 12(a)(xv) [Accounts], which shall survive for 2 Years and as to the representations set forth in Articles 12(a)(i), 12(a)(viii), 12(a)(ix) and 12(a)(x) (the “Corporate Representations”) and Seller’s Broker representation in Section 15, which shall survive for six (6) years, being the period of the statute of limitations for contract actions (each such period, with respect to the indicated representations and warranties, the “Limitations Period). No action or proceeding may be brought with respect to any of the representations or warranties contained herein unless written notice thereof, setting forth in reasonable detail the claimed breach of representation or warranty referencing this Article 16 shall have been delivered to the address set forth in Article 18 hereof prior to the end of the applicable Limitations Period. Those covenants that contemplate or involve actions to be taken or obligations to be in effect after the Closing shall survive in accordance with their terms. Notwithstanding the aforementioned, all representations, warranties and covenants related to tax matters including without limitation the Tax Representations in Section 12(b), and which matters are otherwise primarily set forth in Article 14, shall survive the Closing as described in Article 14(f)(vi).

(ii) To the extent that Buyer has actual knowledge at or prior to Closing that Seller’s representations or warranties contained in this Contract, in any Seller’s Estoppel Certificate or elsewhere are inaccurate, untrue or incorrect in any way, Buyer shall notify Seller in writing and provide Seller ten (10) days to cure such breach and such representations and warranties shall be deemed modified to reflect Buyer’s actual knowledge to the extent set forth in such notice. Except as otherwise provided herein or as included or intended to be included in the Seller’s Tax Indemnity and/or indemnity for the matters described in Section 16(b)(3), and otherwise absent fraud on the part of Seller, the Company or any LLC, Seller shall have no liability to Buyer, after Closing with respect to a breach of representation by Seller if actually known by Buyer, and in the absence of Seller’s cure of such breach or agreement to cure such breach, and Buyer nonetheless closes.

(iii) Notwithstanding anything in this Contract to the contrary, after

57

Closing, and only with respect to breaches of covenants, representations and warranties of Seller not actually known by Buyer at Closing and first discovered by Buyer after Closing, Seller shall be liable to Buyer only if the aggregate of all actual damages incurred by Buyer or Buyer’s successors and assigns exceeds $50,000 (such floor shall not be applicable to a breach of the Tax Representations or Seller’s covenants made in Section 13(k)), and, if so, such liability shall include the first dollar of such damage and all amounts owed thereafter. In addition, but without limiting Seller’s General Indemnity obligations under Section 16(b), the maximum aggregate liability of Seller and the maximum aggregate amount which may be awarded to and collected by Buyer or Buyer’s successors and assigns (a) for all breaches of Seller’s representations made in Section 12(a) other than Corporate Representations and Tax Representations shall in no event exceed Ten Million Dollars ($10,000,000); (b) with respect to breaches of Tax Representations (including any liability under the indemnity provisions of Section 16(c)) shall not exceed One Hundred Million Dollars ($100,000,000); and (c) with respect to breaches of Corporate Representations shall not exceed Two Hundred Thirty-Three Million Eight Hundred Thirty Two Thousand Five Hundred Dollars ($233,832,500) if written claim of such breach is made within six (6) months after the Closing and One Hundred Million Dollars ($100,000,000) if written claim is made thereafter.

(b) General Indemnity. As of the Closing, and without limiting any other rights or remedies of Buyer, Seller shall indemnify, defend and hold harmless Buyer (and its respective affiliates, officers, managers, directors, partners, owners, members and shareholders (including any of the above persons taxable on a flow-through or conduit basis on the income of the same) and their respective successors and assigns, and as applicable, each LLC) (collectively, “Buyer Indemnitees”) from and against any and all Claims that may be imposed, suffered, incurred or incurred by Buyer or any Buyer Indemnitee as to a breach or violation of any Retained Liability (as herein defined).

“Retained Liability” shall mean and include any Excluded Liability; and the Surviving Seller Obligations; and any and all Claims relating thereto, including without limitation, the following; but provided that unless otherwise covered below (in which event if covered below, there shall be no cap or limitation on survival), the survival period and cap for a breach of representations set forth in Section 12(a) shall be governed by Section 16(a) above:

(1) under or with respect to any Lease, Service Contract, Personal Property Lease, management or leasing agreement or commission agreement or other agreement, promise or covenant, guaranty or indemnity (whether or not now in effect) or the Loan Documents (including a breach of representation, warranty or covenant thereunder) or filing with any governmental or quasi governmental authority including without limitation any income and expense filing (whether known or unknown) arising or accruing with respect to the period prior to the date of Closing and not otherwise expressly accepted by Buyer as to such period or which

58

would not otherwise be assumed by Buyer if Buyer was purchasing only the LLC Owner Property rather than the Shares or the 4250 N. Fairfax Interest, including, by way of example and not limitation, bankruptcy preference claims of any existing or prior tenant, vendor or supplier of the Property (or of any Excluded Assets) or any portion thereof,

(2) in connection with any pending or threatened Litigation, Claim, suit or proceeding against the Company or any LLCs relating to occurrences or matters first arising prior to Closing (whether or not initiated prior or after Closing), including without limitation the HQ Global Bankruptcy, the Cosi Allegation (subject to the limitations set forth in this Contract) and any other existing litigation, claims, suit or proceeding involving the Company or any LLC (whether known or unknown), or with respect to audits permitted under any Lease which audits are either in process or remain outstanding or prospective as of Closing but limited to liability for any period prior to the Closing;

(3) under or with respect to any Subsidiary (other than the LLCs), Excluded Liability, Excluded Contract or Excluded Asset, Other First Loan, 4250 N. Fairfax Loan (whether known or unknown) and whether arising or accruing before or after Closing including, without limitation, any litigation, claims, suits or proceedings involving any Subsidiary (other than the LLCs) or any Excluded Assets whether known or unknown and whether arising or accruing before or after Closing, but not including herein any matters for which the Buyer Indemnitees are indemnified under Section 14(c) below;

(4) any loss or Claim in connection with a breach by Seller (or Seller entities) to the non-Seller members under or with respect to the Organizational Documents of the Eye Street Owner LLCs, the Eye Street Loan Documents or the MTA Agreement arising or occurring prior to the Closing Date; and

(5) If Seller has any claim or rights to pursue claims against the other parties to the MTA Agreement, and such claim is not a Surviving Obligation of Seller, Seller, at Buyer’s request, shall assert such claim on behalf of Buyer and any proceeds received in connection therewith shall be paid to Buyer. To the extent that Seller has made Buyer whole with respect to any breach by Seller of any Surviving Obligation and Seller has a surviving claim against any such parties to the MTA Agreement as to the same breach, Seller shall be entitled to seek reimbursement from the other parties to the MTA Agreement with respect to such claim and shall be entitled to retain all rights to the proceeds thereof (unless by doing so, Buyer is not made whole on other claims that would otherwise be covered by Beacon’s rights under the MTA that Beacon is required to exercise on Buyer’s behalf.).

59

(c) Tax Indemnities

(1) In addition to and without limiting any other indemnity obligations of Seller hereunder, Seller shall indemnify, defend, and hold harmless Buyer Indemnitees from and against any and all Claims asserted against, resulting to, imposed on, sustained, incurred or suffered by, or asserted against the Buyer Indemnitees, directly or indirectly, by reason of or resulting from: (a) all Taxes imposed upon the Company or any of the Subsidiaries with respect to any taxable period or portion thereof ending on or before the Closing Date (“Pre-Closing Periods”), and for any Straddle Periods, but only with respect to the portion of any such Straddle Period ending on the Closing Date and calculated in the manner provided in Section 14(f) of this Contract, (b) any breach or inaccuracy in any Tax Representation, without regard to any qualifications for knowledge of the Sellers, but only for the Tax Survival Period; provided that if such liability for a Tax Representation is otherwise separately intended to be covered such time limitation is not intended as limitation, (c) any breach or failure by Seller to perform (or cause to be performed) any of the covenants or agreements set forth in Section 14(d)(3), Section 14(f) or this Section 16(c) (including, without limitation, all the provisions hereof regarding the maintenance of the Company as a REIT), (d) any Taxes related to any Excluded Asset or the divesture of any Excluded Asset (whether known or unknown by Buyer prior to Closing) and any litigation, claims, suit or proceeding involving any Subsidiary (other than the LLCs) or any Excluded Assets whether known or unknown and whether arising or accruing before or after Closing; and (e) Tax liability under D.C. Code Annotated §42-1103 arising in connection with the transfer of the Shares because of a transfer by any person (as defined in D.C. Code Annotated §42-1101(6)) of any direct or indirect beneficial interest in either 1201 Owner or 1225 Owner prior to the Closing (including the transfer of the Shares) other than any direct or indirect transfer by or through the Company or any of its Subsidiaries occurring after the Closing. The maximum liability of Seller under this Section 16(c)(1), together with Seller’s liability for breach of the Tax Representations shall not exceed One Hundred Million Dollars ($100,000,000) in the aggregate.

(ii) Buyer shall indemnify, defend, and hold harmless Seller (and its respective affiliates, officers, managers, directors, partners, owners, members and shareholders (including any of the above persons taxable on a flow-through or conduit basis on the income of same), and their respective successors and assigns) (collectively, “Seller Indemnitees”) from and against any and all Losses asserted against, resulting to, imposed on, sustained, incurred or suffered by, or asserted against the Seller Indemnitees, directly or indirectly, by reason of or resulting from: (1) all Taxes imposed upon the Company or any of the Subsidiaries [other than Subsidiaries required to be divested as provided in Section 13(k)] with respect to any taxable period or portion thereof beginning after the Closing (“Post-Closing Periods”), and for any Straddle Periods, but only with respect to the portion of any such Straddle Period from and after the Closing and calculated in the manner provided in Section 14(f) of this Contract, and (2) any breach or failure by Buyer to perform (or cause to be performed) any of the covenants or agreements set forth in Section 14(f) or this Section 16(c) (including, without limitation, all the provisions hereof regarding the maintenance of the Company as a real estate investment trust from and after the Closing until the end of the Company Straddle

Taxable year), provided the maximum aggregate liability of the Buyer with respect thereto shall not exceed One Hundred Million Dollars ($100,000,000). Wells Real Estate Investment Trust, Inc. by its execution of this Contract hereby agrees that it and its successors and assigns shall be jointly and severally liable with Wells Operating Partnership, L.P. and its successors and assigns for the indemnity obligations set forth herein and Wells Operating Partnership, L.P. and its successors and assigns shall remain liable hereunder notwithstanding any assignment of this Contract pursuant to Article 20(b) or otherwise.

(iii) For purposes of this Section 16(c), in order to apportion appropriately any Taxes relating to a Straddle Period, the parties hereto shall, to the extent permitted under Applicable Law, elect with the relevant tax authority to treat for all Tax purposes the Closing Date as the last day of the taxable year or period of the Company and the Subsidiaries. In any case where Applicable Law does not permit the Company or the Subsidiaries to treat the Closing Date as the last day of the taxable year or period, the portion of any Taxes that are allocable to the portion of the Straddle Period ending on the Closing Date shall be:

(1) In the case of Taxes that are imposed on a periodic basis (such as real property taxes), deemed to be the amount of such Taxes for the entire period (or, in the case of such Taxes determined on an arrears basis, the amount of such Taxes for the immediately preceding period) multiplied by a fraction the numerator of which is the number of calendar days in the Straddle Period ending on (and including) the Closing Date and the denominator of which is the number of calendar days in the entire relevant Straddle Period; and

(2) In the case of Taxes not described in clause (1) above (such as Taxes that are either (x) based upon or related to income or receipts, or (y) imposed in connection with any sale or other transfer or assignment of property (real or personal, tangible or intangible), deemed equal to the amount that would be payable if the taxable year or period ended on the Closing Date.

The provisions of this clause (iii) shall not be applicable to the payment of real estate and personal property taxes and assessments on any property owned by the LLCs, provision for which is made elsewhere in this Contract.

(iv) All amounts payable or to be paid by one party hereto to the other party hereof under this Section 16(c) (the “Tax Indemnity Payments”) shall be paid in immediately available funds within ten (10) Business Days after the later of (i) receipt of a written request from an Indemnitee entitled to such Tax Indemnity Payment and (ii) the day of payment of the amount that is the subject of the Tax Indemnity Payment by an Indemnitee entitled to receive the Tax Indemnity Payment. The parties agree to treat any indemnification payment made pursuant to this Contract as an adjustment to the Purchase Price for all Tax purposes.

61

(d) In connection with and as support for (but not in limitation of) Seller’s indemnity obligations hereunder, Seller agrees to maintain a net worth of not less than [$100,000,000.00] for a period of three (3) years after Closing; and [$30,000,000] thereafter until the expiration of the Tax Survival Period. If, however, Seller dissolves, liquidates or otherwise reorganizes or the stated term of Seller (as set forth in its organizational documents) expires (each an “Event”) prior to the expiration of the Tax Survival Period, then Seller shall reserve (in a manner acceptable to Buyer) [$100,000,000] through the end of such initial three (3) year period after Closing, and [$30,000,000] thereafter until (i) the earlier of the expiration of the Tax Survival Period or until (ii) (x) the expiration of the fourth year after Closing if the Event occurs prior to the expiration of the three (3) year period or (y) one year after the Event if the Event occurs after the expiration of the three (3) year period. Seller shall provide written notice to Buyer at least ninety (90) days prior to the occurrence of an Event other than the expiration of its term and at least one (1) year written notice prior to the expiration of the term of Seller. Furthermore, in the event an unresolved Claim is outstanding at the time this net worth covenant would otherwise be reduced or terminated, Seller shall maintain a net worth or reserve of 125% of the amount of the Claim until the Claim is finally resolved. Such obligation of Seller shall expressly survive Closing and shall be in addition to all other obligations and covenants of Seller hereunder and is not intended to, and shall not in any way be deemed to, limit Seller’s indemnity or other covenants or obligations hereunder in amount, time, or scope or otherwise.

(e) Indemnification Procedures

(i) Unless the parties otherwise mutually agree, a claim by any Buyer Indemnitee or Seller Indemnitee (as applicable, the “Indemnitee”) for indemnification pursuant to this Article 16 (an “Indemnification Claim”) shall be made by the Indemnitee by delivery of a written notice to the indemnifying party (the “Indemnitor”) requesting indemnification and reasonably identifying the basis on which indemnification is sought and, if available, the amount (or estimate) of asserted damages and, in the case of a Third Party Claim, as defined below, containing (by attachment or otherwise) such other information as the Indemnitee shall have concerning such Third Party Claim. A “Third Party Claim” means any Litigation instituted against the Indemnitee that, if prosecuted successfully, would be a matter for which the Indemnitee is entitled to indemnification under this Agreement.

(ii) If the Indemnification Claim involves a Third Party Claim, the procedures set forth in Section 16(f) hereof shall be observed by the Indemnitee and Seller.

(iii) If the Indemnification Claim involves a matter other than a Third Party Claim, Indemnitor shall have thirty (30) days to object to such Indemnification Claim by delivery of a written notice of such reasonable objection to the Indemnitee specifying in reasonable detail the basis for such objection. Failure to timely so object shall constitute a final and binding acceptance of the Indemnification Claim by Indemnitor and the Indemnification Claim shall be paid in accordance with Section 16(e)(iv) hereof. If an objection is timely interposed by Seller, then the Indemnitee and Indemnitor shall negotiate in good faith for a period of up to fifteen (15) days from the date (such period is hereinafter referred to as the “Negotiation Period”) the Indemnitee receives such objection. After the

62

Negotiation Period, if Indemnitor and Indemnitee still cannot agree on an Indemnification Claim, either Indemnitor or the Indemnitee may submit the dispute concerning such Indemnification Claim for resolution to arbitration as set forth in Section 16(h); provided, however, nothing herein shall prevent the parties from seeking equitable or injunctive relief in a court of equity with respect to such dispute.

(iv) Upon determination of the amount of an Indemnification Claim that is binding on both Indemnitor and the Indemnitee, Seller shall pay the amount of such Indemnification Claim by wire transfer of immediately available funds within ten (10) days of the date such amount is determined.

(f) Defense of Third Party Claims.

(i) In the event of a Third Party Claim, Indemnitor shall have thirty (30) days (or such lesser time as may be necessary to comply with statutory response requirements for litigation claims that are included in such Third Party Claims provided the Indemnitee has given notice of such Third Party Claim after receipt thereof; provided further that failure of Indemnitee to timely notify Indemnitor will not relieve Indemnitor of its obligations hereunder unless any delay in such notice results in the inability of Indemnitor to defend such Third Party Claim) from receipt of the Indemnification Claim (the “Notice Period”) to notify the Indemnitee, (i) whether or not Indemnitor disputes its liability to the Indemnitee with respect to such claim, and (ii) notwithstanding any such dispute, whether or not Indemnitor will, at its sole cost and expense, defend the Indemnitee against such claim.

(ii) In the event that Indemnitor notifies the Indemnitee within the Notice Period that it will defend the Buyer Indemnitee against such claim then, except as hereinafter provided, Indemnitor shall have the right, or at Indemnitee’s reasonable election the obligation, to defend the Indemnitee by appropriate proceedings, which proceedings shall be promptly settled or prosecuted by Indemnitor to a final conclusion, provided, Indemnitor shall not agree to any settlement which would result in Indemnitee becoming subject to liability for any other significant matter. If Buyer desires to participate in, but not control, any such defense or settlement, it may do so at its sole cost and expense.

If Buyer desires to participate in, but not control, any such defense or settlement, it may do so at its sole cost and expense. If in the reasonable opinion of the Buyer Indemnitee, any such claim or the litigation or resolution of any such claim involves an issue or matter that could have a future material adverse effect on the Buyer Indemnitee and involves a continuing relationship of Buyer with respect to the Property, Company or LLCs, including, without limitation, a dispute with a current tenant, licensee or governmental entities having jurisdiction over the Property or Company or LLCs with respect to the Property and its ongoing operation, the Buyer Indemnitee shall have the right to jointly participate in the defense or settlement of any such claim or demand and its reasonable costs and expenses shall be included as part of the indemnification obligation of Seller Indemnitor, and no settlement shall be made without the reasonable concurrence of both parties.

63

(iii) Except where Indemnitor disputes its liability in a timely and reasonable manner under this Section 16(f), Indemnitor shall be conclusively liable for the amount of any loss or other damage resulting from such claim or defense.

(iv) the Indemnitee and Indemnitor shall cooperate with each other in all reasonable respects in connection with the defense of any Third Party Claim, including making available records relating to such claim.

(g) Settlement of Third Party Claims. Any settlement of a Third Party Claim shall include an unconditional term releasing the Indemnitee from all liability in respect of such asserted liability.

(h) Arbitration.

(i) Any dispute, controversy or claim arising out of or relating to this Agreement or any related document or the performance by the parties of its or their terms shall be settled by binding arbitration held in Washington, DC. The Commercial Arbitration Rules of the American Arbitration Association are hereby incorporated by reference; provided, however, that the parties do not intend any arbitration hereunder to be administered by the American Arbitration Association. The interpretation and enforceability of this Section 16(h) shall be governed exclusively by the Federal Arbitration Act, 9 U.S.C. § 1-16.

(ii) The panel to be appointed shall consist of three neutral arbitrators. One arbitrator shall be appointed by the Buyer Indemnitee and one arbitrator shall be appointed by Seller within fifteen (15) days after the commencement of the arbitration proceeding. The third arbitrator shall be appointed by mutual agreement of the two selected arbitrators and shall be experienced in corporate contractual and real estate matters relating to transactions of the nature contemplated by this Agreement.

(iii) The arbitrators shall allow such discovery as the arbitrators determine appropriate under the circumstances and shall resolve the dispute as expeditiously as practicable. The Federal Rules of Civil Procedure (the “FRCP”) are hereby incorporated by reference for purposes of the discovery process; provided that the FRCP may be waived by the parties by written agreement, or by any appointed arbitrator. The arbitrators shall give the parties written notice of the decision, with the reasons therefor set out, and shall have fifteen (15) days thereafter to reconsider and modify such decision if any party so requests within seven (7) days after the decision. Thereafter, the decision of the arbitrator(s) shall be final, binding, and conclusive with respect to all persons, including persons who have failed or refused to participate in the arbitration process.

(iv) The arbitrators shall have authority to award relief under legal or equitable principles, including interim or preliminary relief, and to allocate responsibility for the costs of the arbitration and to award recovery of attorneys’ fees and expenses in such manner as is determined to be appropriate by the arbitrators.

(v) Judgment upon the award rendered by the arbitrators may be entered in any court having in personam and subject matter jurisdiction.

64

(vi) All proceedings under this Section 16(h), and all evidence given or discovered pursuant hereto, shall be maintained in confidence by all parties.

(vii) The fact that the dispute resolution procedures specified in this Section 16(h) shall have been or may be invoked shall not excuse any party from performing its obligations under this Agreement or any related agreement and during the pendency of any such procedure all parties shall continue to perform their respective obligations in good faith, subject to any rights to terminate this Agreement or any related agreement that may be available to any party.

(viii) All applicable statutes of limitation shall be tolled while the procedures specified in this Section 16(h) are pending. The parties will take such action, if any, required to effectuate such tolling.

17. Escrow Provisions. Escrow Agent shall deliver the Deposit to Seller or Buyer promptly after receiving a joint written notice from Seller and Buyer directing the disbursement of the same, such disbursement to be made in accordance with such direction. If Escrow Agent receives written notice from Buyer or Seller that the party giving such notice is entitled to the Deposit, which notice shall describe with reasonable specificity the reasons for such entitlement, then Escrow Agent shall (i) promptly give written notice to the other party of Escrow Agent’s receipt of such notice and enclosing a copy of such notice and (ii) subject to the provisions of the following paragraph which shall apply if a conflict arises, on the fourteenth (14^th) day after the giving of the notice referred to in clause (i) above, deliver the Deposit to the party claiming the right to receive it; provided further that if Buyer requests a refund of the Initial Deposit on or prior to the expiration of the Due Diligence Period (whether or not such request is also executed by Seller), Escrow Agent shall promptly disburse the Deposit to Buyer in accordance with that request. Buyer and Seller hereby agree to send to the other, a duplicate copy of any written notice sent to Escrow Agent and requesting any such disbursement or countermanding a request for disbursement

In the event that Escrow Agent shall be uncertain as to its duties or actions hereunder or shall receive instructions or a notice from the Buyer or Seller which are in conflict with instructions or a notice from the other party or which, in the reasonable opinion of Escrow Agent, are in conflict with any of the provisions of this Contract, it shall be entitled to take any of the following courses of action:

(i) Hold the Deposit as provided in this Contract and decline to take any further action until Escrow Agent receives a joint written direction from the Buyer and Seller or any order of a court of competent jurisdiction directing the disbursement of the Deposit, in which case Escrow Agent shall then disburse the Deposit in accordance with such direction;

(ii) In the event of litigation between the Buyer and Seller, Escrow Agent may deliver the Deposit to the clerk of any court in which such litigation is pending; or

65

(iii) Escrow Agent may deliver the Deposit to a court of competent jurisdiction and therein commence an action for interpleader, the cost thereof to Escrow Agent to be borne by whichever of the Buyer or Seller does not prevail in the litigation.

A. Escrow Agent shall not be liable for any action taken or omitted in good faith and believed by it to be authorized or within the rights or powers conferred upon it by this Contract and it may rely, and shall be protected in acting or refraining from acting in reliance upon an opinion of counsel and upon any directions, instructions, notice, certificate, instrument, request, paper or other documents believed by it to be genuine and to have been made, sent, signed or presented by the proper party or parties. Escrow Agent shall be under no obligation to take any legal action in connection with the Deposit or this Contract or to appear in, prosecute or defend any action or legal proceedings which would or might, in its reasonable opinion, involve it in cost, expense, loss or liability unless, in advance, and as often as reasonably required by it. Notwithstanding any other provision of this Contract, the Buyer and Seller jointly indemnify and hold harmless Escrow Agent against any loss, liability or expense incurred without bad faith or negligence on its part and arising out of or in connection with its services under the terms of this Contract, including the cost and expense of defending itself against any claim of liability other than arising out of its bad faith or negligence.

B. Escrow Agent shall not be bound by any modification of this Contract affecting Escrow Agent’s duties hereunder unless the same is in writing and signed by the Buyer, Seller and Escrow Agent. From time to time on or after the date of this Contract, the Buyer and Seller shall deliver or cause to be delivered to Escrow Agent such further documents and instruments that fall due, or cause to be done such further acts as Escrow Agent may reasonably request (it being understood that the Escrow Agent shall have no obligation to make any such request) to carry out more effectively the provisions and purposes of this Contract, to evidence compliance with this Contract or to assure itself that it is protected in acting hereunder.

C. Escrow Agent shall serve hereunder without fee for its services as escrow agent, but shall be entitled to reimbursement for its reasonable actual expenses incurred hereunder, which expenses shall be paid and borne equally by the Buyer and Seller. Escrow Agent agrees that it will not seek reimbursement for the services of its employees or partners, but only for its actual and reasonably incurred out-of-pocket expenses.

D. Escrow Agent agrees not to resign unless a substitute Escrow Agent is appointed by the Buyer and Seller and any letters of credit constituting the Deposit are reissued in the name of the substitute Escrow Agent.

18. Notices. Any notice, request, demand, consent, approval and other communications under this Contract shall be in writing, and shall be deemed duly given or made at the time and on the date when received by facsimile (provided that the sender of such communication shall orally confirm receipt thereof by the appropriate parties and send a copy of such communication to the appropriate parties within one (1) business day

66

of such facsimile) or when personally delivered as shown on receipt therefor (which shall include delivery by a nationally recognized overnight delivery service) or three (3) business days after being mailed by prepaid registered or certified mail, return receipt requested, to the address for each party set forth below.
