3.3. Condition of the Properties.

(a) The parties hereto acknowledge that Purchaser has employed independent zoning consultants, and engineering and/or environmental professionals to review zoning and to perform engineering, environmental and physical assessments on Purchaser’s behalf in respect of the Properties and the condition thereof. Purchaser and Sellers mutually acknowledge and agree that the Properties are being sold in an “AS IS” condition and “WITH ALL FAULTS,” known or unknown, contingent or existing. Purchaser has the sole responsibility to fully inspect the Properties, to investigate all matters relevant thereto, including, without limitation, the condition of the Properties, and to reach its own, independent evaluation of any risks (environmental or otherwise) or rewards associated with the ownership, leasing, management and operation of the Properties; and Purchaser hereby acknowledges and agrees that it has been afforded sufficient time and access to the Properties, the tenants of such Properties and books and records relating to the Properties to fully inspect the Properties, to investigate all matters relevant thereto, including, without limitation, the condition of the Properties, and to reach its own, independent evaluation of all risks (environmental or otherwise) or rewards associated with the ownership, leasing, management and operation of the Properties. Effective as of the Closing and except as expressly set forth in this Agreement, Purchaser hereby waives and releases Sellers and each of them, and their respective officers, directors, shareholders, members, partners, agents, affiliates, employees and successors and assigns from and against any and all claims, obligations and liabilities arising out of or in connection with the Properties.

(b) To the fullest extent permitted by law, Purchaser does hereby unconditionally waive and release Sellers, and each of them, and their respective officers, directors, shareholders, members, partners, agents, affiliates and employees from any present or future claims and liabilities of any nature arising from or relating to the presence or alleged presence of Hazardous Substances in, on, at, from, under or about the Properties or any adjacent property, including, without limitation, any claims under or on account of any Environmental Law, regardless of whether such Hazardous Substances are located in, on, at, from, under or about the Properties or any adjacent property prior to or after the date hereof (collectively, “Environmental Liabilities”); provided, however, that the foregoing release as it applies to any Seller, its officers, directors, shareholders, members, partners, agents, affiliates and employees, shall not release such

Seller, or its general partners or members from any Environmental Liabilities of (i) such Seller relating to any Hazardous Substances which may be placed, located or released on any of the Properties by any Seller after the date of Closing, or (ii) the general partners or members of such Seller relating to any Hazardous Substances which may be placed, located or released by any Seller after the date of Closing. The terms and provisions of this Section 3.3 shall survive the Closing.

3.4. Title and Survey. Seller has provided Purchaser with a preliminary title commitment with respect to each of the Properties (individually, a “Seller Title Commitment”, and collectively, the “Sellers’ Title Commitments”). Purchaser has had and shall have the right, but not the obligation, to order from the Title Company, a preliminary title commitment with respect to each of the Properties or updates or revisions to any of Sellers’ Title Commitments (individually, a “Purchaser’s Title Commitment”, and collectively, the “Purchaser’s Title Commitments”). Purchaser shall also have the right to have Lawyers Title Insurance Corporation and/or Land America Title Insurance Company participate with the Title Company in the title insurance to be obtained by Purchaser (and its lenders); provided, however, that no such participation shall result in any obligation of Sellers to pay for any increase in the cost of “standard” or “base” title insurance coverage for any policy or policies of owner’s title insurance coverage issued to Purchaser with respect to the Properties at Closing as a result of such title insurance participation by Lawyers Title Insurance Corporation and/or Land America Title Insurance Company (or any of its or their affiliated title companies). Purchaser shall direct the Title Company to send a copy of each of the Purchaser’s Title Commitments to Sellers. “Title Commitment” shall mean a Seller’s Title Commitment or a Purchaser’s Title Commitment. The Seller’s Title Commitments and Purchaser’s Title Commitments are collectively referred to as the “Title Commitments”. Sellers and Purchaser mutually acknowledge and agree that prior to the Effective Date, Sellers and Purchaser have made arrangements for the preparation of one or more updates of each Existing Survey (and in the case of the Alstom Power Property, the Americredit Property, the Kerr McGee Property, the Nissan Property and the Traveler’s Express Property, Sellers and Purchaser have made arrangements for as-built Surveys to be prepared where no such as-built survey currently exists) (individually, a “Survey”, and collectively, the “Surveys”). Copies of all such Surveys and any updates or revisions to any of the same shall be made available concurrently to Sellers and Purchasers. From time to time at any time after the Effective Date of this Agreement and prior to the Closing Date, Purchaser may give written notice to Seller’s Counsel (a “Subsequent Title Notice”) of exceptions to title first appearing of record with respect to such Property after the effective date of the most recent previous Title Commitment or updated Title Commitment with respect to such Property or matters of survey, which matters of record or matters of survey would not have been disclosed by an accurate updated examination of title or preparation of an updated ALTA survey prior to date of the most recently revised Title Commitment or the most recently revised Survey with respect to such Property. Sellers shall have the right, but not the obligation (except as to Monetary Objections), to attempt to remove, satisfy or otherwise cure any exceptions to title to which the Purchaser so objects. Within five (5) Business Days after receipt of any Subsequent Title Notice, Sellers shall give written notice to Purchaser’s Counsel informing the Purchaser of the election of Sellers with respect to the objections in such Subsequent Title Notice. If Sellers fail to give written notice of election within such five (5) Business Day period, Sellers shall be deemed to have elected not to attempt to cure the objections (other than Monetary Objections)

set forth in such Subsequent Title Notice; it being specifically understood and agreed that except as specifically set forth in this Agreement to the contrary, Sellers have elected not to attempt to cure any objections (other than Monetary Objections) set forth in any of the notices of title and survey objections and comments provided by Purchaser’s Counsel to Sellers’ Counsel prior to the Effective Date of this Agreement. If Sellers elect to attempt to cure any objections, Sellers shall be entitled to one or more reasonable adjournments of the Closing of up to but not beyond the thirtieth (30th) day following the initial date set for the Closing to attempt such cure, but, except for Monetary Objections, Sellers shall not be obligated to expend any sums, commence any suits or take any other action to effect such cure. Except as to Monetary Objections, if Sellers elect, or are deemed to have elected, not to cure any exceptions to title to which Purchaser has objected or if, after electing to attempt to cure, Sellers determine that they are unwilling or unable to remove, satisfy or otherwise cure any such exceptions, Purchaser’s sole remedy hereunder in such event shall be either (i) to accept title to the applicable Property subject to such exceptions as if Purchaser had not objected thereto and without reduction of the Purchase Price, (ii) if such exceptions are matters first appearing of record or first disclosed by any Survey or updated Title Commitment after the date of this Agreement, to terminate this Agreement as to such Property or Properties, or (iii) to terminate this Agreement within three (3) Business Days after receipt of written notice from Sellers either of the election of Sellers not to attempt to cure any objection or of the determination of Sellers, having previously elected to attempt to cure, that Sellers are unable or unwilling to do so, or three (3) Business Days after Sellers are deemed hereunder to have elected not to attempt to cure such objections (and upon any such termination under clause (iii) above, Escrow Agent shall return the Earnest Money to Purchaser). Notwithstanding anything to the contrary contained elsewhere in this Agreement, Sellers shall be obligated to cure or satisfy all Monetary Objections at or prior to Closing, and may use the proceeds of the Purchase Price at Closing for such purpose.

3.5. Service Contracts. At Closing, Purchaser shall assume the obligations of Sellers arising from and after Closing under all of the Service Contracts relating to each Property that is the subject of such Closing; provided, however, Seller shall be required to terminate any Service Contracts which are with any Seller-Related Entities. Subject to the foregoing, and taking into account any credits or prorations to be made pursuant to Article 5 hereof for payments coming due after Closing but accruing prior to Closing, Purchaser will assume the obligations arising from and after the Closing Date under the Service Contracts.

3.6. Confidentiality. All information acquired by Purchaser or any of its designated representatives (including by way of example, but not in limitation, the officers, directors, shareholders and employees of Purchaser, and Purchaser’s engineers, consultants, counsel and potential lenders, and the officers, directors, shareholders and employees of each of them) with respect to the Properties, whether delivered by Sellers or any representatives of Sellers or obtained by Purchaser as a result of its inspection and investigation of the Properties, examination of the books, records and files of Sellers in respect of the Properties, or otherwise (collectively, the “Due Diligence Material”) shall be used solely for the purpose of determining whether the Properties are suitable for Purchaser’s acquisition and ownership thereof and for no other purpose whatsoever. Prior to Closing, the terms and conditions which are contained in this Agreement and all Due Diligence Material which is not published as public knowledge or which is not generally available in the public domain shall be kept in strict confidence by Purchaser and

shall not be disclosed to any individual or entity other than to those authorized representatives of Purchaser and Purchaser’s prospective and actual counsel, accountants, professionals, consultants, attorneys and lenders, who need to know the information for the purpose of assisting Purchaser in evaluating the Properties for Purchaser’s potential acquisition thereof; provided, however, that Purchaser shall have the right to disclose any such information if required by applicable law or as may be necessary in connection with any court action or proceeding with respect to this Agreement. Purchaser shall and hereby agrees to indemnify and hold Sellers and each of them harmless from and against any and all loss, liability, cost, damage or expense that Sellers or any of them may suffer or incur (including, without limitation, reasonable attorneys’ fees actually incurred) as a result of the unpermitted disclosure of any of the Due Diligence Material to any individual or entity other than an appropriate representative of Purchaser and Purchaser’s prospective and actual counsel, accountants, professionals, consultants, attorneys and lenders, and/or the use of any Due Diligence Material for any purpose other than as herein contemplated and permitted. The foregoing indemnity shall not extend to disclosure of any Due Diligence Material (i) as may be required by applicable law, or (ii) that is or becomes public knowledge other than by virtue of a breach of Purchaser’s covenant under this Section 3.6. If Purchaser or Sellers elect to terminate this Agreement pursuant to any provision hereof permitting such termination, or if the Closing contemplated hereunder fails to occur for any reason, Purchaser will promptly return to Sellers all Due Diligence Material in the possession of Purchaser and any of its representatives, and destroy all copies, notes or abstracts or extracts thereof, as well as all copies of any analyses, compilations, studies or other documents prepared by Purchaser or for its use (whether in written or electronic form) containing or reflecting any Due Diligence Material. In the event of a breach or threatened breach by Purchaser or any of its representatives of this Section 3.6, Sellers and each of them shall be entitled, in addition to other available remedies, to an injunction restraining Purchaser or its representatives from disclosing, in whole or in part, any of the Due Diligence Material and any of the terms and conditions of this Agreement. Nothing contained herein shall be construed as prohibiting or limiting Sellers from pursuing any other available remedy, in law or in equity, for such breach or threatened breach. The provisions of this Section shall survive any termination of this Agreement.

(a) Taxes. All general real estate taxes imposed by any governmental authority (“Taxes”) shall be prorated between Purchaser and each Seller as to the Taxes with respect to the Properties of such Seller as of the Closing. If the Closing occurs prior to the receipt by Sellers of the tax bill for any of the Properties for the calendar year or other applicable tax period in which the Closing occurs, Taxes with respect to such Property or Properties shall be prorated for such calendar year or other applicable tax period based upon the prior year’s tax bill. Notwithstanding the foregoing, Taxes shall not be prorated with respect to any Property as to which the tenant under the Lease(s) with respect to such Property is obligated to pay Taxes directly to the applicable taxing authority.

(b) Reproration of Taxes. After receipt of final Taxes and other bills, Purchaser shall prepare and present to each Seller a calculation of the reproration of such Taxes and other items with respect to the Properties of such Seller, based upon the actual amount of such items charged to or received by the parties for the year or other applicable fiscal period. Purchaser and each Seller shall make the appropriate adjusting payment between them within thirty (30) days after presentment to such Seller of Purchaser’s calculation and appropriate back-up information. Purchaser shall provide each Seller with appropriate backup materials related to the calculation, and each Seller may inspect Purchaser’s books and records related to the Properties of such Seller to confirm the calculation. The provisions of this Section 5.4(b) shall survive the Closing for a period of one (1) year after the Closing Date.

(c) Rents, Income and Other Expenses. As to each Seller, rents and any other amounts (including Taxes) paid by tenants of the Properties of such Seller shall be prorated as of

the Closing Date and be adjusted against the Purchase Price allocated to such Seller on the basis of a schedule which shall be prepared by such Seller and delivered to Purchaser for Purchaser’s review and approval at least five (5) Business Days prior to Closing. With respect to each Seller, Purchaser shall receive at Closing a credit for Purchaser’s pro rata share of the rents, additional rent, common area maintenance charges, tenant reimbursements and escalations, and all other payments paid for the month of Closing with respect to the Properties of such Seller and for all other rents and other amounts with respect to the Properties of such Seller that apply to periods from and after the Closing, but which are received by such Seller prior to Closing. Purchaser agrees to pay to each Seller, upon receipt, any rents or other payments by tenants under their respective Leases with respect to the Properties of such Seller that apply to periods prior to Closing but are received by Purchaser after Closing; provided, however, that any delinquent rents or other payments by tenants shall be applied first to any current amounts owing by such tenants from and after Closing, then to delinquent rents in the order in which such rents are most recently past due, with the balance, if any, paid over to such Seller to the extent of delinquencies existing at the time of Closing to which such Seller is entitled; it being understood and agreed that Purchaser shall not be legally responsible to such Seller for the collection of any rents or other charges payable with respect to such Leases or any portion thereof, which are delinquent or past due as of the Closing Date; but Purchaser agrees that Purchaser shall send monthly notices for a period of three (3) consecutive months in an effort to collect any rents and charges not collected as of the Closing Date. With respect to each Seller, any reimbursements payable by any tenant under the terms of any tenant lease affecting any of the Properties of such Seller as of the Closing Date, which reimbursements pertain to such tenant’s pro rata share of increased operating expenses or common area maintenance costs incurred with respect to such Properties at any time prior to the Closing, shall be prorated upon Purchaser’s actual receipt of any such reimbursements, on the basis of the number of days of such Seller’s and Purchaser’s respective ownership of such Properties during the period in respect of which such reimbursements are payable; and Purchaser agrees to pay to such Seller such Seller’s pro rata portion of such reimbursements within thirty (30) days after Purchaser’s receipt thereof. Conversely, if any tenant under any such Lease affecting the Properties of such Seller shall become entitled at any time after Closing to a refund of tenant reimbursements actually paid by such tenant prior to Closing, then, such Seller shall, within thirty (30) days following Purchaser’s demand therefor, pay to Purchaser an amount equal to such Seller’s pro rata share of such reimbursement refund obligations, said proration to be calculated on the same basis as hereinabove set forth. The applicable Sellers shall be and remain responsible for the payment of all Florida sales tax that may be payable on rents and rental income paid by the tenants under their leases affecting the Americredit Property and the Gartner Property, respectively, prior to the Closing Date (and to the extent that the tenants under such Leases are required to reimburse the landlord for all or any part of such Florida sales tax, such tenant reimbursement paid with respect to the rents payable for all periods prior to the Closing Date shall belong to the applicable Sellers). Conversely, Purchaser shall be responsible for the payment of all Florida sales tax that may be payable on rents and rental income paid by such tenants under their Leases for all periods from and after the Closing Date (and to the extent that the tenants under such Leases are required to reimburse the landlord for all or any part of such Florida sales tax, such tenant reimbursements with respect to rents paid by such tenants for all periods from and after the Closing Date shall belong to Purchaser). Each Seller hereby retains its right to pursue any tenant under the Leases affecting the Properties of such Seller for sums due such Seller for periods attributable to such Seller’s ownership of such Properties; provided, however, that such Seller (i) shall be required to

notify Purchaser in writing of its intention to commence or pursue such legal proceedings, and to provide Purchaser with copies of all correspondence with such tenant relative to such proceedings; (ii) shall only be permitted to commence or pursue any legal proceedings after the date which is three (3) months after Closing, except that such Seller shall be entitled to continue to pursue any legal proceedings commenced prior to Closing; and (iii) shall not be permitted to commence or pursue any legal proceedings against any tenant seeking eviction of such tenant or the termination of the applicable Lease. The provisions of this Section 5.4(c) shall survive the Closing for a period of eighteen (18) months after the Closing Date; provided, however, that in the event the tenant under any Lease affecting any Property currently has rights to audit operating expenses under its Lease for calendar year 2005 which extend beyond eighteen (18) months after the Closing Date of such Property, then as to any such Property and Lease, the provisions of this Section 5.4(c) shall survive the Closing for a period of time equal to any such tenant’s audit rights under such Lease.

(d) Security Deposits. As to each Seller, Purchaser shall receive at Closing a credit with respect to the Purchase Price allocated to such Seller for all Security Deposits transferred and assigned to Purchaser at Closing in connection with the Leases affecting the Properties of such Seller, together with a detailed inventory of such Security Deposits.

(e) Operating Expenses. As to each Seller, personal property taxes, installment payments of special assessment liens, vault charges, sewer charges, utility charges, and normally prorated operating expenses actually paid or payable as of the Closing Date with respect to the Properties of such Seller (including, without limitation, amounts payable pursuant to the Service Contracts and Property Management Agreements) shall be prorated as of the Closing Date and adjusted against the Purchase Price allocated to such Seller, provided that within ninety (90) days after the Closing, Purchaser and such Seller will make a further adjustment for such taxes, charges and expenses affecting the Properties of such Seller which may have accrued or been incurred prior to the Closing Date, but not collected or paid at that date. In addition, as to each Seller, within ninety (90) days after the close of the fiscal year(s) used in calculating the pass-through to tenants of operating expenses and/or common area maintenance costs under the Leases affecting the Properties of such Seller (where such fiscal year(s) include(s) the Closing Date), such Seller and Purchaser shall, upon the request of either, re-prorate on a fair and equitable basis in order to adjust for the effect of any credits or payments due to or from tenants for periods prior to the Closing Date. All prorations shall be made based on the number of calendar days in such year or month, as the case may be. Notwithstanding the foregoing, personal property taxes, installment payments of special assessment liens, vault charges, sewer charges, utility charges, and operating expenses shall not be prorated with respect to any Property as to which the tenant under the Lease(s) with respect to such Property is obligated to pay the same directly to the provider thereof. The provisions of this Section 5.4(e) shall survive the Closing for a period of eighteen (18) months after the Closing Date; provided, however, that in the event the tenant under any Lease affecting any Property currently has rights to audit operating expenses under its Lease for calendar year 2005 which extend beyond eighteen (18) months after the Closing Date of such Property, then as to any such Property and Lease, the provisions of this Section 5.4(e) shall survive the Closing for a period of time equal to any such tenant’s audit rights under such Lease.

(f) Tenant Inducement Costs.

(i) At the Closing of the ISS Property, Purchaser shall receive a credit against the Purchase Price of such Property in the amount of $888,076.88, said sum representing the unpaid tenant improvement allowance payable to the tenant under and pursuant to the Lease for Building 3 of the ISS Property. At such Closing, Purchaser shall assume the obligation to pay such tenant improvement allowance to such tenant as and when the same becomes payable pursuant to the terms of said Lease.

(ii) At the Closing of the John Wiley Property, Purchaser shall receive credits against the Purchase Price of such Property (x) in the amount of $69,492.00, said sum representing the unpaid tenant improvement allowance payable to John Wiley & Sons, Inc. under and pursuant to its Lease at the John Wiley Property as set forth on the attached Exhibit ”I”, and (y) in the amount of $48,239.00, said sum representing the unpaid leasing commission payable to CB Richard Ellis, Inc. in connection with the Lease with John Wiley & Sons, Inc. pursuant to the Commission Agreement described on the attached Exhibit “C”.

Subject to the last paragraph of this Section 6.1, the delivery of Ground Lessor Estoppel Certificates from the ASML Prime Ground Lessor, the ASML Sub-Ground Lessor and the Ingram Micro Ground Lessor shall be a condition of Closing, and the failure or inability of Wells OP to obtain and deliver said Ground Lessor Estoppel Certificates, Wells OP having used its good faith efforts to obtain the same from the ground lessors under the Ground Leases, shall not constitute a default by Wells OP under this Agreement;

(g) Association Estoppel Certificates. An Association Estoppel Certificate from each of the Associations listed on the attached EXHIBIT “D” shall have been delivered to Purchaser, with each such Association Estoppel Certificate (i) to be dated within thirty (30) days prior to the First Closing Date, and (ii) to confirm (A) the absence of any material defaults or violations by the applicable Seller with respect to the payment of any assessments (whether annual, periodic or special) to such Association with respect to the applicable Property or Properties owned by such Seller as “owner”, (B) the amount of any annual, periodic or regular assessments and specific assessments to become payable by the owner of the applicable Property and as to which such Association has given written notice to such Seller prior to or concurrently with the date of such Association Estoppel Certificate, (C) if the Association (or architectural review committee, board or other group) is required under the terms of the applicable Declaration to confirm that the plans and specifications for the applicable Wells OP Improvements or Wells Affiliate Improvements have been approved as may be required under the terms of such Declaration, then a statement that such plans and specifications have been so approved, and (D) all amendments or modifications of the applicable Declaration; provided, however, that if the closing of purchase and sale of any Property is adjourned or postponed beyond the First Closing Date set forth in Section 2.7(a) hereof for any reason permitted under this Agreement or as otherwise may be agreed by Seller and Purchaser and Sellers theretofore shall have obtained and delivered an Association Estoppel Certificate meeting the requirements of this Section 6.1(g) and dated within thirty (30) days of the First Closing Date, then this condition shall be deemed satisfied as to such Property and Sellers shall have no obligation to seek or obtain an updated Association Estoppel Certificate as to such Property to comply with clause (i) hereinabove. Subject to the last paragraph of this Section 6.1, the delivery of said Association Estoppel Certificates from such Associations shall be a condition of Closing, and the failure or inability of Sellers to obtain and deliver said Association Estoppel Certificates, each applicable Seller having used its good faith efforts to obtain the same shall not constitute a default by Sellers under this Agreement. Notwithstanding anything to the contrary contained

herein, if the applicable Seller has been unable to obtain and deliver to Purchaser by Closing the applicable Association Estoppel Certificate meeting the requirements set forth above, then, at the option of such Seller, this condition to Closing may be satisfied by such Seller’s execution and delivery to Purchaser at Closing, on behalf of any Association having rights with respect to the Property of such Seller and which has failed to provide the required Association Estoppel Certificate an estoppel certificate substantially in the form attached hereto as SCHEDULE 20 (“Seller’s Estoppel”); and provided that the applicable Seller’s liability under any such Seller’s Estoppel so executed and delivered by such Seller to Purchaser at Closing shall cease and terminate upon the receipt by Purchaser after Closing of a duly executed Association Estoppel Certificate from the Association covered in such Seller’s Estoppel to the extent that such Association Estoppel Certificate conforms to Seller’s Estoppel in all material respects; and

(h) Declarant Estoppel Certificates. A Declarant Estoppel Certificate from each of the Declarants under the Declarations shall have been delivered to Purchaser, with each such estoppel certificate (i) to be dated within thirty (30) days prior to the Closing Date, and (ii) to confirm (A) the absence of any material defaults or violations under the applicable Declaration by the applicable Seller as “owner” as defined in such Declaration, (B) the payment of all amounts due from such Seller, (C) if Declarant is required under the terms of the applicable Declaration to confirm that the plans and specifications for the applicable Wells OP Improvements or Wells Affiliate Improvements have been approved as may be required under the terms of such Declaration, then a statement that such plans and specifications have been so approved, and (D) all amendments or modifications of the applicable Declaration. Subject to the last paragraph of this Section 6.1, the delivery of said Declarant Estoppel Certificates from such Declarants shall be a condition of Closing, and the failure or inability of Sellers to obtain and deliver said Declarant Estoppel Certificates, each applicable Seller having used its good faith efforts to obtain the same, shall not constitute a default by Sellers under this Agreement; provided, however, that if the closing of purchase and sale of any Property is adjourned or postponed beyond the initial First Closing Date set forth in Section 2.7(a) hereof for any reason permitted under this Agreement or as otherwise may be agreed by Seller and Purchaser and Sellers theretofore shall have obtained and delivered an Declarant Estoppel Certificate meeting the requirements of this Section 6.1(h) and dated within thirty (30) days of said initial First Closing Date, then this condition shall be deemed satisfied as to such Property and Sellers shall have no obligation to seek or obtain an updated Declarant Estoppel Certificate as to such Property to comply with clause (i) hereinabove. Notwithstanding anything to the contrary contained herein, if the applicable Seller has been unable to obtain and deliver to Purchaser by Closing the applicable Declarant Estoppel Certificate meeting the requirements set forth above, then, at the option of such Seller, this condition to Closing may be satisfied by such Seller’s execution and delivery to Purchaser at Closing, on behalf of any Declarant having rights with respect to the Property of such Seller and which has failed to provide the required Declarant Estoppel Certificate, a Seller’s Estoppel substantially in the form attached hereto as SCHEDULE 20; and provided that the applicable Seller’s liability under any such Seller’s Estoppel so executed and delivered by such Seller to Purchaser at Closing shall cease and terminate upon the receipt by Purchaser after Closing of a duly executed Declarant Estoppel Certificate from the Declarant covered in such Seller’s Estoppel to the extent that such Declarant Estoppel Certificate conforms to Seller’s Estoppel in all material respects.

(i) Gartner Lease Amendment and ISS Lease Amendment. The Gartner Lease Amendment as executed by Wells Funds XI and XII REIT JV and Gartner, Inc., and the ISS Lease Amendment as executed by Wells OP and Internet Security Systems, Inc., each of which lease amendments shall be substantially in the forms attached hereto as Exhibit “CC” and Exhibit “DD”, respectively. Subject to the last paragraph of this Section 6.1, the delivery of the Gartner Lease Amendment and the ISS Lease Amendment shall be conditions to Closing, and the failure or inability of Sellers to obtain and delivery either of said lease amendments, each applicable Seller having used its good faith efforts to obtain the same from said tenants, shall not constitute a default by Sellers hereunder.

(j) Final C.O.’s for Alstom Power Property and Capital One Property. The delivery by Wells Virginia REIT and Wells OP to Purchaser of copies of final certificates of occupancy for all improvements located on the Alstom Power Property and the Capital One Property, or the delivery by Wells Virginia REIT and Wells OP to Purchaser of other evidence satisfactory to Purchaser that final certificates of occupancy have been issued by the applicable governing authorities for all improvements located on the Alstom Power Property and the Capital One Property.

In the event any condition in this Section 6.1 has not been satisfied (or otherwise waived in writing by Purchaser) prior to or on the Closing Date (as the same may be extended or postponed as provided in this Agreement), Purchaser shall have the right to terminate this Agreement by written notice to Sellers given prior to the Closing, whereupon (i) Escrow Agent shall promptly return the Earnest Money to Purchaser; and (ii) except for those provisions of this Agreement which by their express terms survive the termination of this Agreement, no party hereto shall have any other or further rights or obligations under this Agreement.

6.2. Conditions Precedent to Sellers’ Obligations. The obligations of Sellers hereunder to consummate the transactions contemplated hereunder shall in all respects be conditioned upon the satisfaction of each of the following conditions prior to or simultaneously with the Closing (or at such earlier time as may be provided below), any of which may be waived by Sellers in their sole discretion by written notice to Purchaser at or prior to the Closing Date:

(a) Purchaser shall have paid and Sellers shall have received the Purchase Price, as adjusted pursuant to the terms and conditions of this Agreement, which Purchase Price shall be payable in the amount and in the manner provided for in this Agreement;

(b) Purchaser shall have performed, in all material respects, all covenants, agreements and undertakings of Purchaser contained in this Agreement; and

(c) All representations and warranties of Purchaser as set forth in this Agreement shall be true and correct in all material respects as of the date of this Agreement and as of Closing, provided that solely for purposes of this subparagraph such warranties and representations shall be deemed to be given without being limited to Purchaser’s knowledge and without modification (by update or otherwise, as provided in Section 5.2 hereof).

6.3. Conditions Precedent to Purchase and Sale of Certain Properties.

(a) In addition to and not in lieu of Sections 6.1 and 6.2 above, the respective obligations of Purchaser and Sellers to consummate the transaction contemplated hereunder with respect to the Bank of America Property shall in all respects be conditioned upon the failure (or deemed failure) of Bank of America NT & SA, as tenant under its Lease affecting the Bank of America Property, to timely exercise its right to purchase the Bank of America Property pursuant to the terms of its Lease. In the event that the Outstanding ROFO/ROFR Party shall timely exercise its right to purchase the Bank of America Property, Sellers shall promptly notify Purchaser in writing thereof, which notice shall be accompanied by a true and correct copy of the notice of exercise received by the applicable Seller (“Seller’s Partial Termination Notice”). Upon the delivery by Seller to Purchaser of Seller’s Partial Termination Notice, this Agreement shall terminate the Bank of America Property which is the subject of Seller’s Partial Termination Notice, whereupon (1) the aggregate Purchase Price for the Properties as set forth in Section 2.5 hereof shall be reduced by the Purchase Price for the Bank of America Property as set forth on EXHIBIT “O” attached hereto; (2) Escrow Agent shall promptly return the Earnest Money allocated to the Bank of America Property (i.e., $1,500,000.00) to Purchaser; (3) the parties hereto shall proceed to close the purchase and sale of the other Properties which are the subject of this Agreement; and (4) except for those provisions of this Agreement which by their express terms survive the termination of this Agreement, no party hereto shall have any other or further rights or obligations under this Agreement with respect to the Bank of America Property.

(b) In addition to and not in lieu of Section 6.1 and Section 6.2 above, the respective obligations of Purchaser and Seller to consummate the transactions contemplated hereunder with respect to the ASML Property and the Ingram Micro Property shall in all respects be conditioned upon the written approval or consent of the lessors under the ASML Prime Ground Lease, the ASML Sub-Ground Lease and the Ingram Micro Bond Lease to the transfers, respectively, of the leasehold estates in the ASML Property and the Ingram Micro Property to Purchaser.

ARTICLE 7.

CASUALTY AND CONDEMNATION

7.1. Casualty. Risk of loss up to and including the Closing Date shall be borne by Sellers. In the event of any immaterial damage or destruction to the Properties of a Seller or any portion thereof, Sellers and Purchaser shall proceed to close under this Agreement, and Purchaser will receive (and the applicable Seller whose Property or Properties was or were the subject of such damage or destruction will assign to Purchaser at the Closing such Seller’s rights under insurance policies to receive) any insurance proceeds (including any rent loss insurance applicable to any period on and after the Closing Date) due such Seller as a result of such damage or destruction (less any amounts reasonably expended for restoration or collection of proceeds) and assume responsibility for such repair, and Purchaser shall receive a credit at Closing for any deductible amount under said insurance policies. For purposes of this Agreement, the term “immaterial damage or destruction” shall be applied on a Property by Property basis and shall mean such instances of damage or destruction of the subject Property:

(i) which can be repaired or restored at a cost equal to or less than an amount equal to five percent (5%) of the Purchase Price of such Property, as set forth on the attached Exhibit “O”; (ii) which can be restored and repaired within one hundred eighty (180) days from the date of such damage or destruction; (iii) which are not so extensive as to allow any Major Tenant of such Property to terminate its Lease with respect to such Property or abate or reduce rent payable thereunder (unless business loss or rent insurance shall be available in the full amount of such abatement or reduction, subject to applicable deductibles) on account of such damage or destruction; and (iv) in which such Seller’s rights under its rent loss insurance policies covering such Property are assignable to Purchaser and will continue pending restoration and repair of the damage or destruction.

In the event of any material damage or destruction to one or more of the Properties or any portion thereof, Purchaser may, at its option, by notice to Sellers given within the earlier of twenty (20) days after Purchaser is notified by Sellers of such damage or destruction, or the Closing Date, but in no event less than ten (10) days after Purchaser is notified by Seller of such damage or destruction (and if necessary the Closing Date shall be extended to give Purchaser the full 10-day period to make such election): (i) terminate this Agreement as to any such Property which is the subject of material damage or destruction (an “Excluded Property”), or (ii) proceed to close under this Agreement, receive (and each Seller will assign to Purchaser at the Closing the rights of such Seller under insurance policies to receive) any insurance proceeds (including any rent loss insurance applicable to the period on or after the Closing Date) due such Seller as a result of such damage or destruction (less any amounts reasonably expended for restoration or collection of proceeds) and assume responsibility for such repair, and Purchaser shall receive a credit at Closing for any deductible amount under said insurance policies. If Purchaser fails to deliver to Sellers notice of its election within the period set forth above, Purchaser will conclusively be deemed to have elected to proceed with the Closing as provided in clause (ii) of the preceding sentence. If Purchaser elects clause (ii) above, each Seller will cooperate with Purchaser after the Closing to assist Purchaser in obtaining the insurance proceeds from the insurers of such Seller. For purposes of this Agreement “material damage or destruction” shall mean all instances of damage or destruction that are not immaterial, as defined herein.

7.2. Condemnation. If, prior to the Closing, all or any part of the Properties of a Seller is subjected to a bona fide threat of condemnation by a body having the power of eminent domain or is taken by eminent domain or condemnation (or sale in lieu thereof), or if a Seller has received written notice that any condemnation action or proceeding with respect to the Properties of such Seller is contemplated by a body having the power of eminent domain (collectively, a “Taking”), such Seller shall give Purchaser immediate written notice of such Taking. In the event of any immaterial Taking with respect to the Properties of a Seller or any portion thereof, Sellers and Purchaser shall proceed to close under this Agreement. For purposes of this Agreement, the term “immaterial Taking” shall be applied on a Property by Property basis and shall mean such instances of Taking of the subject Property: (i) which do not result in a taking of any portion of the building structure of the building occupied by tenants on such Property; (ii) which do not result in a decrease in the number of parking spaces at such Property (taking into account the number of additional parking spaces that can be provided within one hundred eighty (180) days of such Taking); and (iii) which are not so extensive as to allow any Major

Tenant of such Property to terminate its Lease with respect to such Property or abate or reduce rent payable thereunder [unless business loss or rent insurance (subject to applicable deductibles) or condemnation award proceeds shall be available in the full amount of such abatement or reduction, and Purchaser shall receive a credit at Closing for such deductible amount] on account of such Taking.

In the event of any material Taking of one or more of the Properties or any portion thereof (any such Property also being referred to in this Agreement as an “Excluded Property”), Purchaser may, at its option, by written notice to Sellers given within thirty (30) days after the receipt of such notice from such Seller, elect to terminate this Agreement only as to any such Excluded Property. If Purchaser chooses to terminate this Agreement as to any such Excluded Property in accordance with this Section 7.2, then the rights, duties, obligations, and liabilities of the parties hereunder shall immediately terminate as to any such Excluded Property only and be of no further force and effect, except for those provisions of this Agreement which by their express terms survive the termination of this Agreement. For purposes of this Agreement “material Taking” shall mean all instances of a Taking that are not immaterial, as defined herein.

If Purchaser does not elect to, or has no right to, terminate this Agreement as to any Property in accordance herewith on account of a Taking, this Agreement shall remain in full force and effect and the sale of the Properties contemplated by this Agreement, less any interest taken by eminent domain or condemnation, or sale in lieu thereof, shall be effected with no further adjustment and without reduction of the Purchase Price, and at the Closing, each Seller shall assign, transfer, and set over to Purchaser all of the right, title, and interest of such Seller in and to any awards applicable to the Properties of such Seller that have been or that may thereafter be made for such taking. At such time as all or a part of the Properties of a Seller is subjected to a bona fide threat of condemnation and Purchaser shall not have elected to terminate this Agreement as to any such Excluded Property only as provided in this Section 7.2, and provided that the Inspection Period has expired and Purchaser has delivered the Earnest Money to Escrow Agent, (i) Purchaser shall thereafter be permitted to participate in the proceedings as if Purchaser were a party to the action, and (ii) such Seller shall not settle or agree to any award or payment pursuant to condemnation, eminent domain, or sale in lieu thereof without obtaining Purchaser’s prior written consent thereto in each case.

ARTICLE 8.

DEFAULT AND REMEDIES

8.1. Purchaser’s Default. If Purchaser fails to consummate this transaction for any reason other than the default of Sellers, failure of a condition to Purchaser’s obligation to close, or the exercise by Purchaser of an express right of termination granted herein, Sellers shall be entitled, as their sole remedy hereunder, to terminate this Agreement and to receive and retain the Earnest Money as full liquidated damages for such default of Purchaser, the parties hereto acknowledging that it is impossible to estimate more precisely the damages which might be suffered by Sellers upon Purchaser’s default, and that said Earnest Money is a reasonable estimate of the probable loss of Sellers in the event of default by Purchaser. The retention by Sellers of said Earnest Money is intended not as a penalty, but as full liquidated damages. The

right to retain the Earnest Money as full liquidated damages is the sole and exclusive remedy of Sellers in the event of default hereunder by Purchaser, and Sellers hereby waive and release any right to (and hereby covenant that they shall not) sue the Purchaser: (a) for specific performance of this Agreement, or (b) to recover actual damages in excess of the Earnest Money. The foregoing liquidated damages provision shall not apply to or limit Purchaser’s liability for Purchaser’s obligations under Sections 3.1(b), 3.1(c), 3.7 and 10.1 of this Agreement or for Purchaser’s obligation to pay to Sellers all attorney’s fees and costs of Sellers to enforce the provisions of this Section 8.1. Purchaser hereby waives and releases any right to (and hereby covenants that it shall not) sue Sellers or either of them or seek or claim a refund of said Earnest Money (or any part thereof) on the grounds it is unreasonable in amount and exceeds the actual damages of Sellers or that its retention by Sellers constitutes a penalty and not agreed upon and reasonable liquidated damages.

8.2. Seller’s Default. If Sellers or any of them fail to perform any of their respective obligations under this Agreement for any reason other than Purchaser’s default or the permitted termination of this Agreement by Sellers or any of them or Purchaser as expressly provided herein, Purchaser shall be entitled, as its sole remedy, either (a) to receive the return of the Earnest Money from Escrow Agent, which return shall operate to terminate this Agreement and release Sellers from any and all liability hereunder; provided, however, that in the event, and only in the event, such default by any Seller was willful and intentional and Purchaser receives the return of the Earnest Money, then Sellers shall pay to Purchaser an amount equal to the lesser of (i) Purchaser’s actual out-of-pocket expenditures incurred directly in conducting due diligence activities contemplated under this Agreement and in negotiating and finalizing this Agreement, or (ii) Ten Million and No/100 Dollars ($10,000,000.00), or (b) to enforce specific performance of the obligation of each Seller to execute and deliver the documents required to convey the Property owned by such Seller to Purchaser in accordance with this Agreement; it being specifically understood and agreed that the remedy of specific performance shall not be available to enforce any other obligation of Sellers or any of them hereunder. Notwithstanding the foregoing, if after January 7, 2005, any Seller shall have conveyed title to such Seller’s Property to another party (other than to the Outstanding ROFO/ROFR Party pursuant to the timely exercise by such Outstanding ROFO/ROFR Party of its ROFO/ROFR Rights) or intentionally and knowingly taken any other action to defeat the remedy of specific performance, Purchaser shall be entitled to seek actual damages from Sellers. Except as expressly provided to the contrary in this Section 8.2, Purchaser expressly waives its rights to seek damages in the event of the default of Sellers or any of them hereunder. Purchaser shall be deemed to have elected to terminate this Agreement and to receive a return of the Earnest Money applicable to such Property from Escrow Agent if Purchaser fails to file suit for specific performance against each applicable Seller who is in breach of its obligations hereunder in a court having jurisdiction on or before sixty (60) days following the date upon which the Closing was to have occurred.

ARTICLE 9.

ASSIGNMENT

9.1. Assignment. Subject to the next following sentence, this Agreement and all rights and obligations hereunder shall not be assignable by any party without the written consent of the other. Notwithstanding the foregoing to the contrary, (i) this Agreement and all of

Purchaser’s rights hereunder may be transferred and assigned to any entity controlled by Purchaser or one or more of Purchaser’s joint venture partners, and (ii) only contemporaneously with the Closing hereunder, Purchaser’s rights under this Agreement with respect to any one or more of the separate Properties may be transferred and assigned to any entity controlled by Purchaser or one or more of Purchaser’s joint venture partners so that the applicable Property or Properties as to which the transfer and assignment relates shall be conveyed to the applicable assignee and such assignee shall become the “Purchaser” under this Agreement as to such Property or Properties. Any assignee or transferee under any such assignment or transfer by Purchaser as to which the written consent of Seller has been given or as to which the consent of Seller is not required hereunder shall expressly assume all of Purchaser’s duties, liabilities and obligations under this Agreement (whether arising or accruing prior to or after the applicable assignment or transfer) by written instrument delivered to Seller as a condition to the effectiveness of such assignment or transfer, except that any assignee or transferee under a transfer or assignment effectuated contemporaneously with the Closing under clause (ii) of the preceding sentence shall be required to assume only such of Purchaser’s duties, liabilities and obligations under this Agreement that relate to the particular Property or Properties as to which the transfer and assignment relates, and upon such assumption by the assignee or transferee, except for the duties and obligations arising under Purchaser’s indemnities set forth in Sections 3.1(c) and 10.1 of this Agreement, the original Purchaser shall be released and shall have no further liabilities, duties or obligations under this Agreement that relate to such particular Property or Properties as to which the transfer and assignment relates. No assignment or transfer effectuated under clause (i) of this Section 9.1 shall relieve the original Purchaser of any duties or obligations hereunder, and the written assignment and assumption agreement shall expressly so provide. No assignment or transfer effectuated under clause (ii) above shall relieve the original Purchaser of any duties and obligations arising under Purchaser’s indemnities set forth in Sections 3.1(c) and 10.1 hereof. For purposes of this Section 9.1, the term “control” shall mean the ownership of at least fifty percent (50%) of the applicable entity. Subject to the foregoing, this Agreement shall be binding upon and shall inure to the benefit of the parties hereto and their respective legal representatives, successors and permitted assigns. This Agreement is not intended and shall not be construed to create any rights in or to be enforceable in any part by any other persons.

ARTICLE 10.

BROKERAGE COMMISSIONS

10.1. Broker. Upon the Closing, and only in the event the Closing occurs, Sellers shall pay a brokerage commission to Eastdil Realty Company, LLC, a New York limited liability company (“Broker”), pursuant to a separate agreement between Sellers and Broker. Broker is representing Sellers in this transaction. Broker has joined in the execution of this Agreement for the purpose of acknowledging and agreeing that no real estate commission shall be earned by it or due it if the transaction contemplated herein does not close for any reason whatsoever. Broker acknowledges and agrees that it shall look solely to Sellers, and not to Purchaser, for the payment of such commission, and Broker hereby waives and releases any present or future claims against Purchaser for the payment of such commission. In addition, Broker (upon receipt of its brokerage commission) agrees to execute and deliver to Sellers and Purchaser at the Closing a release and waiver of any claim Broker may have against Purchaser or the Properties.

Broker shall and does hereby indemnify and hold Purchaser and Sellers harmless from and against any and all liability, loss, cost, damage, and expense, including reasonable attorneys’ fees actually incurred and costs of litigation, Purchaser or Sellers shall ever suffer or incur because of any claim by any agent, salesman, or broker, whether or not meritorious, for any fee, commission or other compensation with regard to this Agreement or the sale and purchase of the Properties contemplated hereby, and arising out of any acts or agreements of Broker. Each Seller shall and does hereby indemnify and hold Purchaser harmless from and against any and all liability, loss, cost, damage, and expense, including reasonable attorneys’ fees actually incurred and costs of litigation, Purchaser shall ever suffer or incur because of any claim by any agent, salesman, or broker, whether or not meritorious, for any fee, commission or other compensation with regard to this Agreement or the sale and purchase of the Properties contemplated hereby, and arising out of any acts or agreements of such Seller, including any claim asserted by Broker. Likewise, Purchaser shall and does hereby indemnify and hold Sellers free and harmless from and against any and all liability, loss, cost, damage, and expense, including reasonable attorneys’ fees actually incurred and costs of litigation, Sellers shall ever suffer or incur because of any claim by any agent, salesman, or broker, whether or not meritorious, for any fee, commission or other compensation with respect to this Agreement or the sale and purchase of the Properties contemplated hereby and arising out of the acts or agreements of Purchaser. This Section 10.1 shall survive the Closing until the expiration of any applicable statute of limitations and shall survive any earlier termination of this Agreement.

ARTICLE 11.

INDEMNIFICATION

11.1. Indemnification by Sellers. Following the Closing and subject to Sections 11.3 and 11.4, each Seller shall indemnify and hold Purchaser, its affiliates, members and partners, and the partners, shareholders, officers, directors, employees, representatives and agents of each of the foregoing (collectively, “Purchaser-Related Entities”) harmless from and against any and all costs, fees, expenses, damages, deficiencies, interest and penalties (including, without limitation, reasonable attorneys’ fees and disbursements) suffered or incurred by any such indemnified party in connection with any and all losses, liabilities, claims, damages and expenses (“Losses”), arising out of, or in any way relating to, (a) any breach of any representation or warranty of such Seller contained in this Agreement or in any Closing Document, and (b) any breach of any covenant of such Seller or of Sellers jointly contained in this Agreement which survives the Closing or in any Closing Document.

11.2. Indemnification by Purchaser. Following the Closing and subject to Sections 11.3 and 11.4, Purchaser (and Purchaser’s joint venture partners to whom any rights of Purchaser are assigned pursuant to Section 9.1 hereof) shall indemnify and hold Sellers, their respective affiliates, members and partners, and the partners, shareholders, officers, directors, employees, representatives and agents of each of the foregoing (collectively, “Seller-Related Entities”) harmless from any and all Losses arising out of, or in any way relating to, (a) any breach of any representation or warranty by Purchaser contained in this Agreement or in any Closing Document, and (b) any breach of any covenant of Purchaser contained in this Agreement which survives the Closing or in any Closing Documents.

11.3. Limitations on Indemnification. Notwithstanding the foregoing provisions of Section 11.1, (a) Sellers shall not be required to indemnify Purchaser or any Purchaser Related Entities under this Agreement unless the aggregate of all amounts for which an indemnity would otherwise be payable by Sellers under Section 11.1 above exceeds the Basket Limitation and, in such event Sellers shall be responsible for only the amount in excess of the Basket Limitation (the “Excess Amount”), with Wells OP responsible only for that amount equal to the Excess Amount multiplied by a fraction, the numerator of which is the sum of (i) the individual liability of Wells OP under Section 11.1 above, plus (ii) a percentage of the joint (and not individual) liability of Sellers under Section 11.1 above, with such percentage to be equal to one one-hundredth (1/100^th) multiplied by the quotient obtained by dividing the total Purchase Price for the Wells OP Properties by the total Purchase Price for all of the Properties, and with each Wells Affiliate responsible only for that amount equal to the Excess Amount multiplied by a fraction, the numerator of which is the sum of (i) the individual liability of such Wells Affiliate under Section 11.1 above, plus (ii) a percentage of the joint (and not individual) liability of Sellers under Section 11.1 above, with such percentage to be equal to one one-hundredth (1/100^th) multiplied by the quotient obtained by dividing the Purchase Price for the Wells Affiliate Property owned by such Wells Affiliate by the total Purchase Price for all of the Properties, (b) in no event shall the liability of Sellers with respect to the indemnification provided for in Section 11.1 above exceed in the aggregate the Cap Limitation, (c) if prior to the Closing, Purchaser obtains knowledge in writing of any inaccuracy or breach of any representation, warranty or covenant of Sellers or any of them contained in this Agreement (a “Purchaser-Waived Breach”) and nonetheless proceeds with and consummates the Closing, then Purchaser and any Purchaser-Related Entities shall be deemed to have waived and forever renounced any right to assert a claim for indemnification under this Article 11 for, or any other claim or cause of action under this Agreement, at law or in equity on account of any such Purchaser-Waived Breach, and (d) notwithstanding anything herein to the contrary, the Basket Limitation and the Cap Limitation shall not apply with respect to Losses suffered or incurred as a result of breaches of any covenant or agreement of Sellers or any of them set forth in Section 5.3, Section 5.4, Section 10.1, EXHIBIT “R” or “EXHIBIT “V” of this Agreement. Notwithstanding anything to the contrary set forth in Section 11.1 or in this Section 11.3, Wells OP agrees that Wells OP shall be jointly and severally liable with Wells Virginia REIT, Wells Brea, Wells Westlake, Wells Farmington Hills, Wells Kalamazoo and Wells EDS with respect to all obligations of each such party to Purchaser under Section 11.1 above and this Section 11.3.

11.4. Survival. The representations, warranties and covenants contained in this Agreement and the Closing Documents with respect to each Property shall survive until the first (1^st) anniversary of the closing of each such Property, unless a longer or shorter survival period is expressly provided for in this Agreement, or unless prior to such first (1^st) anniversary date of such Closing, Purchaser or Seller, as the case may be, delivers written notice to the other party of such alleged breach specifying with reasonable detail the nature of such alleged breach and files an action with respect thereto within one hundred twenty (120) days after the giving of such notice.

11.5. Indemnification as Sole Remedy. If the Closing has occurred, the sole and exclusive remedy available to a party in the event of a breach by the other party to this Agreement of any representation, warranty, or covenant or other provision of this Agreement or any Closing Document which survives the Closing shall be the indemnifications provided for under Section 3.1(c), Section 10.1, and this Article 11.

12.2 Possession. Full and exclusive possession of the Properties of each Seller, subject to the Permitted Exceptions and the rights of the tenants under the Leases affecting such Properties, shall be delivered by such Seller to Purchaser on the Closing Date.

12.3 Time Periods. If the time period by which any right, option, or election provided under this Agreement must be exercised, or by which any act required hereunder must be performed, or by which the Closing must be held, expires on a Saturday, Sunday, or holiday, then such time period shall be automatically extended through the close of business on the next regularly scheduled Business Day.

12.4 Publicity. The parties agree that, prior to Closing, and except for disclosures required by law or governmental regulations applicable to such party, no party shall, with respect to this Agreement and the transactions contemplated hereby, contact or conduct negotiations with public officials or make any public announcements regarding this Agreement or the transactions contemplated hereby to any third party without the prior written consent of the other party hereto. Except for disclosures required by law or governmental regulations applicable to such party, Sellers and Purchaser shall each deliver to the other the press release of the other party to be issued in connection with the execution of this Agreement and in connection with the Closing no less than three (3) hours during normal business hours on a Business Day prior to the issuance of any such press release. No party shall record this Agreement or any notice hereof; and neither party shall file a copy of this Agreement with the SEC until the filing of their respective Quarterly Reports on Form 10-Q for the current quarter, except for any recording or filing otherwise required under the United States securities laws or as may be required by the SEC; provided, however, that (i) in the event Purchaser is so required, it shall provide Sellers reasonable advance notice of any such required filing, and (ii) any such required filing shall exclude all schedules and exhibits to this Agreement.

12.5 Discharge of Obligations. The acceptance by Purchaser of the Limited Warranty Deeds of Sellers hereunder shall be deemed to constitute the full performance and discharge of each and every warranty and representation made by Sellers or any of them and Purchaser herein and every agreement and obligation on the part of Sellers or either of them and Purchaser to be performed pursuant to the terms of this Agreement, except those warranties, representations, covenants and agreements which are specifically provided in this Agreement to survive Closing.

12.6 Severability. This Agreement is intended to be performed in accordance with, and only to the extent permitted by, all applicable laws, ordinances, rules and regulations. If any provision of this Agreement, or the application thereof to any person or circumstance, shall, for

any reason and to any extent be invalid or unenforceable, the remainder of this Agreement and the application of such provision to other persons or circumstances shall not be affected thereby but rather shall be enforced to the greatest extent permitted by law.

12.7 Construction. This Agreement shall not be construed more strictly against one party than against the other merely by virtue of the fact that this Agreement may have been prepared by counsel for one of the parties, it being mutually acknowledged and agreed that Sellers and Purchaser and their respective counsel have contributed substantially and materially to the preparation and negotiation of this Agreement. Accordingly, the normal rule of construction to the effect that any ambiguities are to be resolved against the drafting party shall not be employed in the interpretation of this Agreement or any exhibits or amendments hereto.

12.8 Sale Notification Letters. Promptly following the Closing, Purchaser shall deliver the Tenant Notices of Sale to each of the respective tenants under the Leases, the Ground Lessor Notices of Sale to each of the respective Ground Lessors under the Wells OP Ground Leases, the Declarant Notices to each of the respective Declarants under the Declarations, and the Other Notices of Sale to each service provider and leasing agent, the obligations under whose respective Service Contracts and Commission Agreements Purchaser has assumed at Closing.

12.9 Access to Records Following Closing. Purchaser agrees that for a period of one (1) year following the Closing, each Seller shall have the right during regular business hours, on five (5) days’ written notice to Purchaser, to examine and review at Purchaser’s office (or, at Purchaser’s election, at the Properties), the books and records of such Seller relating to the ownership and operation of the Properties of such Seller which were delivered by such Seller to Purchaser at the Closing. Likewise, each Seller agrees that for a period of one (1) year following the Closing, Purchaser shall have the right during regular business hours, on five (5) days’ written notice to such Seller, to examine and review at such Seller’s office, all books, records and files, if any, retained by such Seller relating to the ownership and operation by Seller prior to the Closing of the Properties of such Seller. The provisions of this Section shall survive the Closing for a period of one (1) year after the Closing Date.

12.10 Submission to Jurisdiction. Each of Purchaser and Sellers irrevocably submits to the exclusive jurisdiction of (a) the Superior Court of Gwinnett County, Georgia located in Lawrenceville, Georgia, and (b) the United States District Court for the Northern District of Georgia for the purposes of any suit, action or other proceeding arising out of this Agreement or any transaction contemplated hereby. Each of Purchaser and Sellers further agrees that service of any process, summons, notice or document by U.S. registered mail to such party’s respective address set forth above shall be effective service of process for any action, suit or proceeding in Georgia with respect to any matters to which it has submitted to jurisdiction as set forth above in the immediately preceding sentence. Each of Purchaser and Sellers irrevocably and unconditionally waives trial by jury and irrevocably and unconditionally waives any objection to the laying of venue of any action, suit or proceeding arising out of this Agreement or the transactions contemplated hereby in (a) the Superior Court of Gwinnett County, Georgia located in Lawrenceville, Georgia, and (b) the United States District Court for the Northern District of Georgia, and hereby further irrevocably and unconditionally waives and agrees not to plead or claim in any such court that any such action, suit or proceeding brought in any such court has been brought in an inconvenient forum.

12.11 General Provisions. No failure of any party to exercise any power given hereunder or to insist upon strict compliance with any obligation specified herein, and no custom or practice at variance with the terms hereof, shall constitute a waiver of any party’s right to demand exact compliance with the terms hereof. This Agreement contains the entire agreement of the parties hereto, and no representations, inducements, promises, or agreements, oral or otherwise, between the parties not embodied herein shall be of any force or effect. Any amendment to this Agreement shall not be binding upon Sellers or Purchaser unless such amendment is in writing and executed by Sellers and Purchaser. Subject to the provisions of Section 9.1 hereof, the provisions of this Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective heirs, legal representatives, successors, and permitted assigns. Time is of the essence in this Agreement. The headings inserted at the beginning of each paragraph are for convenience only, and do not add to or subtract from the meaning of the contents of each paragraph. This Agreement shall be construed, interpreted and enforced under the laws of the State of Georgia. Except as otherwise provided herein, all rights, powers, and privileges conferred hereunder upon the parties shall be cumulative but not restrictive to those given by law. All personal pronouns used in this Agreement, whether used in the masculine, feminine, or neuter gender shall include all genders, and all references herein to the singular shall include the plural and vice versa.

12.12 Like-Kind Exchange . The parties hereto desire, and each party is willing to cooperate (subject to the limitations set forth below), to effectuate the sale of any one or more of the Properties by means of an exchange of “like-kind” property which will qualify as such under Section 1031 of the Internal Revenue Code of 1986, as amended, and the regulations promulgated thereunder. Each party expressly reserves the right to assign its rights, but not its obligations, hereunder to a qualified intermediary as provided in I.R.C. Reg. 1.1031(k)-1(g)(4) on or before the date of Closing. Upon written notice from either party (a “Requesting Party”) to the other, the party to whom such notice is given (the “Other Party”) agrees to cooperate with the Requesting Party to effect one or more like-kind exchanges with respect to the Property designated by such Requesting Party in its notice to the Other Party, provided that such cooperation shall be subject to the following conditions: (a) such exchange shall not delay the Closing and shall occur either simultaneously with the Closing or the purchase money proceeds payable to such Seller shall be paid, upon such Seller’s prior written direction to Purchaser, to a third party escrow agent or intermediary such that Purchaser shall not be required to participate in any subsequent closing, (b) the Requesting Party shall not be obligated to spend any sums or incur any expenses in excess of the sums and expenses which would have been spent or incurred by the Requesting Party if there had been no exchange, (c) Purchaser shall not be obligated to acquire or accept title to any property other than the applicable Property to be conveyed to Purchaser pursuant to this Agreement, and (d) Seller shall not be obligated to acquire or accept title to any property. The Other Party makes no representation or warranty that the conveyance of any Property or property made pursuant to this Section 12.12 shall qualify for a like-kind exchange. Once Purchaser has paid the purchase money proceeds as directed by such Seller, or such Seller has conveyed the Property as directed by Purchaser, it shall have no further obligation hereunder with respect to such “like-kind” exchange. Each Requesting Party hereby

indemnifies and holds the Other Party harmless from and against any costs, liabilities and expenses incurred or suffered by the Other Party in connection with the “like-kind” exchange or exchanges described herein, which indemnity shall survive the Closing until the expiration of any applicable statute of limitations.

12.13 Attorney’s Fees. If Purchaser or Sellers or any of them brings an action at law or equity against the other in order to enforce the provisions of this Agreement or as a result of an alleged default under this Agreement, the prevailing party in such action shall be entitled to recover court costs and reasonable attorney’s fees actually incurred from the other.

12.14 Counterparts. This Agreement may be executed in one or more counterparts, each of which when taken together shall constitute one and the same original. To facilitate the execution and delivery of this Agreement, the parties may execute and exchange counterparts of the signature pages by facsimile, and the signature page of either party to any counterpart may be appended to any other counterpart.

12.15 Effective Agreement. The submission of this Agreement for examination is not intended to nor shall constitute an offer to sell, or a reservation of, or option or proposal of any kind for the purchase of the Properties. In no event shall any draft of this Agreement create any obligation or liability, it being understood that this Agreement shall be effective and binding only when a counterpart of this Agreement has been executed and delivered by each party hereto.
