Purchaser's sole opinion and discretion, the suitability of the Property for
acquisition by Purchaser. Purchaser shall have the right to terminate this

         of Seller, all necessary action on the part of Seller to authorize the
         transactions herein contemplated has been taken, and no further action
         is necessary for such purpose, and this Agreement constitutes the valid
         and binding agreement of Seller, enforceable in accordance with its
         terms, subject to bankruptcy, insolvency and similar laws affecting
         generally the enforcement of creditor's rights. Neither the execution

         Organization or Operating Agreement, (ii) conflict with or result in

         provisions of Section 1445 of the Internal Revenue Code of 1986, as
         amended.

As used herein, the term "Seller's knowledge" shall mean the actual present
knowledge of David C. Stubbs and Christopher S. Park, without investigation or
the need to conduct investigation. At Closing, Seller shall represent and
warrant to Purchaser that all such representations and warranties

                                       9

<PAGE>

of Seller in this Agreement remain true and correct in all material respects as
of the date of the Closing, except for any changes in any such representations
or warranties that occur and are disclosed by Seller to Purchaser expressly and
in writing at any time and from time to time prior to Closing upon their
occurrence, which disclosures shall thereafter be updated by Seller to the date
of Closing. Each and all of the express representations, warranties and
covenants made and given by Seller to Purchaser in this Paragraph 8 shall
survive the execution and delivery of the Special Warranty Deed by Seller to
Purchaser for a period of one (1) year after the Closing whereupon they shall
expire, except to the extent that with respect to any particular alleged breach,
Purchaser gives Seller written notice prior to the expiration of said one (1)
year period of such alleged breach and files an action against Seller with
respect thereto within ninety (90) days after the giving of such notice. If
there is any material change in any representations or warranties and Seller
does not cure or correct such changes prior to Closing, then Purchaser may, at
Purchaser's option, (i) close and consummate the transaction contemplated by
this Agreement, except that after such closing and consummation Purchaser shall
have the right to seek actual monetary damages from Seller not to exceed
$500,000.00 for any such changes knowingly and intentionally caused by Seller or
any such representations or warranties knowingly and intentionally breached by
Seller, or (ii) terminate this Agreement by written notice to Seller, whereupon
the Earnest Money shall be immediately returned to Purchaser, and thereafter the
parties hereto shall have no further rights or obligations hereunder, except
only (1) for such rights or obligations that, by the express terms hereof,
survive any termination of this Agreement and (2) that Purchaser shall have the
right to seek actual monetary damages from Seller for any changes in such
representations and warranties knowingly and intentionally caused by Seller or
any such representations and warranties knowingly and intentionally breached by
Seller, subject to the limitation set forth in Paragraph 16 hereof.

     Except as otherwise expressly provided in this Agreement or in any
documents to be executed and delivered by Seller to Purchaser at the Closing,
Seller has not made, and Purchaser has not relied on, any representation or
warranty, express or implied, regarding the Property, whether made by Seller, on
Seller's behalf or otherwise. Purchaser acknowledges (i) that Purchaser has
entered into this Agreement with the intention of making and relying upon its
own investigation or that of Purchaser's own consultants and representatives
with respect to the physical, environmental, and economic condition of the
Property and (ii) that Purchaser is not relying upon any statements,
representations or warranties of any kind, other than those specifically set
forth in this Agreement or in any document to be executed and delivered by
Seller to Purchaser at the Closing, made (or purported to be made) by Seller or
anyone acting or claiming to act on Seller's behalf. Purchaser shall be provided
the right and opportunity to inspect the Property and, subject to the terms and
conditions of this Agreement, shall purchase the Property in its "as is"
condition, "with all faults".

         14.     Prorations. The following items shall be prorated and/or
                 ----------
credited between Seller and Purchaser as of Midnight preceding the date of
Closing:

                 (a) Rents. Rents, additional rents, operating costs, and other
                     -----
         income of the Property (other than security deposits) collected by
         Seller from the Tenant for the month of Closing. Purchaser shall also
         receive a credit against the Purchase Price payable by Purchaser to
         Seller at Closing for any rents or other sums prepaid by the Tenant for
         any period following the month of Closing, or otherwise. Purchaser
         shall receive a credit against the Purchase Price payable by Purchaser
         to Seller at Closing for the entire amount of the "Capital Reserve"
         paid by the Tenant under the Lease and not theretofore applied to any
         capital expenses as authorized by Section 3.5(b) of the Lease and
         Paragraph 9(c) hereof. Seller hereby acknowledges that Purchaser shall
         not be legally responsible to Seller for the collection of any
         uncollected rent or other income under the Lease that is past due or
         otherwise due and payable as of the date of Closing. Purchaser agrees
         that if (i) Tenant is in arrears on the date of Closing in the payment
         of rent or other charges under such Tenant's Lease, and (ii) upon
         Purchaser's receipt of any rental or other payment from the Tenant,
         such Tenant is, or after application of a portion of such payment will
         be, current under such Lease in the payment of all accrued rental and
         other charges that become due and payable on the date of Closing or
         thereafter and in the payment of any other obligations of the Tenant
         to Purchaser, then Purchaser shall refund to Seller, out of and to the
         extent of the portion of such payment remaining after Purchaser
         deducts therefrom any and all sums due and owing it from the Tenant
         from and after the date of Closing, an amount up to the full amount of
         any arrearage existing on the date of Closing.

                 (b) Property Taxes. Ad valorem taxes are paid by the Tenant
                     --------------
         under the Lease and accordingly shall not be prorated between Seller
         and Purchaser.

                 (c) Utility Charges. Except for utilities which are the direct
                     ---------------
         responsibility of the Tenant to the applicable public or private
         utilities supplier, (i) Seller shall pay all utility bills received
         prior to Closing and shall be responsible for utilities furnished to
         the Property prior to Closing, and (ii) Purchaser shall be responsible
         for the payment of all bills for utilities furnished to the Property
         subsequent to the Closing. Seller and Purchaser hereby agree to prorate
         as of midnight preceding the date of Closing and pay their respective
         shares of all utility bills received subsequent to Closing (if they
         include a service period prior to the date of Closing and are not the
         responsibility of the Tenant to the applicable public or private
         utility supplier), which agreement shall survive Closing. Seller shall
         be entitled to all deposits presently in effect with the utility
         providers.

                                       15

<PAGE>

                 (d) Service Contracts. Charges under the Service Contracts
                     -----------------
         shall be prorated as of Midnight preceding the date of Closing.

                 (e) Other Tenant Charges. Where the Lease contains Tenant
                     --------------------
         obligations for taxes, common area expenses, operating expenses or
         additional charges of any nature, and where Seller shall have collected
         on an estimated basis any portion thereof in excess of amounts owed by
         Seller for such items for the period prior to the date of Closing, then
         there shall be an adjustment and credit given to Purchaser on the date
         of Closing for such excess amounts collected. Purchaser shall apply all
         such excess amounts to the charges owed by Purchaser for such items for
         the period after the date of Closing, and if required by the Lease,
         shall rebate or credit Tenant with any remainder. If it is determined
         subsequent to the Closing that the amount collected during Seller's
         ownership period exceeded expenses incurred during the same period by
         more than the amount previously credited to Purchaser at Closing, then
         Seller shall promptly pay to Purchaser the deficiency. If it is
         determined subsequent to Closing that the amount collected during
         Seller's ownership period exceeded expenses incurred during the same
         period by less than the amount previously credited to Purchaser at
         Closing, then Purchaser shall promptly pay to Seller the overpayment.

The obligations of the parties under this Paragraph 14 shall survive the
Closing. Notwithstanding anything contained in this Agreement to the contrary,
if the Closing occurs on the last day of a month, the foregoing items shall be
prorated and/or credited between Seller and Purchaser as of Midnight of the date
of Closing (instead of Midnight preceding the date of Closing), and in such case
(i) the Purchase Price shall be reduced by $5,000.00, and (ii) appropriate
changes shall be made in the assumption and indemnity provisions of the Blanket
Transfer and Assignment and the Assignment and Assumption of Lease to the end
that Seller shall be responsible thereunder for the period through the date of
Closing, and Purchaser shall be responsible thereunder for the period after the
date of Closing.

         15.     Purchaser's Default. In the event of default by Purchaser under
                 -------------------
the terms of this Agreement, Seller's sole and exclusive remedy shall be to
terminate this Agreement, receive the Earnest Money from Escrow Agent as
liquidated damages, and receive copies of the "Third Party Reports" from
Purchaser, and thereafter the parties hereto shall have no further rights or
obligations hereunder whatsoever. It is hereby agreed that Seller's damages will
be difficult to ascertain and that the Earnest Money constitutes a reasonable
liquidation thereof and is intended not as a penalty, but as fully liquidated
damages. Seller agrees that in the event of a default by Purchaser, it shall not
initiate any proceeding to recover damages from Purchaser, but shall limit its
recovery to the receipt and retention of the Earnest Money and copies of the
Third Party Reports. The limitations on Purchaser's liability under this
Paragraph 15 shall be inapplicable to the liability of Purchaser for payments,
if any, due by Purchaser to Seller under Paragraph 4 hereof. For purposes
hereof, the term "Third Party Reports" shall mean the reports, studies, surveys
and other information furnished to Purchaser by third parties (excluding
Purchaser's attorneys) in connection with the inspection of the Property. The
delivery of the Third Party Reports by Purchaser shall be without warranty or
representation whatsoever, express or implied, including any warranty as to
accuracy or completeness or otherwise.

                                       16

<PAGE>

         16.     Seller's Default. In the event of default by Seller under the
                 ----------------
terms of this Agreement, except as otherwise specifically set forth herein, at
Purchaser's option: (i) Purchaser shall be entitled to an immediate refund of
all but $25.00 of the Earnest Money and to pursue against Seller an action for a
specific performance, or (ii) Purchaser may terminate this Agreement by written
notice to Seller, whereupon the Earnest Money shall be immediately returned by
Escrow Agent to Purchaser, and Seller shall further reimburse to Purchaser the
documented out-of-pocket costs and expenses incurred by Purchaser in connection
with the proposed acquisition of the Property by Purchaser, not to exceed
$50,000.00; provided, however, if Seller knowingly and intentionally breaches
any covenant to be performed by Seller under this Agreement or knowingly and
intentionally causes any representation or warranty to be untrue or knowingly
and intentionally does anything to make impossible or defeat the remedy of
specific performance, Purchaser shall be further entitled to seek actual damages
from Seller up to a maximum of $500,000.00.

         17.     Condemnation. If, prior to the Closing, all or any part of the
                 ------------
Property 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 Seller has received notice that any condemnation action
or proceeding with respect to the Property is contemplated by a body having the
power of eminent domain, Seller shall give Purchaser immediate written notice of
such threatened or contemplated condemnation or of such taking or sale, and
Purchaser may by written notice to Seller given within fifteen (15) days of the
receipt of such notice from Seller, elect to cancel this Agreement. If Purchaser
chooses to cancel this Agreement in accordance with this Paragraph 17, then the
Earnest Money shall be returned immediately to Purchaser by Escrow Agent and the
rights, duties, obligations, and liabilities of the parties hereunder shall
immediately terminate and be of no further force and effect, except for the
obligations of the parties which are herein expressly stated to survive the
termination of this Agreement. If Purchaser does not elect to cancel this
Agreement in accordance herewith, this Agreement shall remain in full force and
effect and the sale of the Property 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, Seller shall assign, transfer, and set over to
Purchaser all of the right, title, and interest of Seller in and to any awards
that have been or that may thereafter be made for such taking. At such time as
all or a part of the Property is subjected to a bona fide threat of condemnation
and Purchaser shall not have elected to terminate this Agreement as hereinabove
provided, Purchaser shall be permitted to participate in the proceedings as if
Purchaser were a party to the action. 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.

         18.     Damage or Destruction. If any of the Improvements shall be
                 ---------------------
destroyed or damaged prior to the Closing, and if either the estimated cost of
repair or replacement exceeds Two Hundred Fifty Thousand Dollars ($250,000.00)
or the damage is such that the Lease is terminated or terminable at the option
of the Tenant (unless the termination option is waived in writing), Purchaser
may, by written notice given to Seller within twenty (20) days after receipt of
written notice from Seller of such damage or destruction, elect to terminate
this Agreement, in which event

                                       17

<PAGE>

the Earnest Money shall immediately be returned by Escrow Agent to Purchaser and
the rights, duties, obligations, and liabilities of all parties hereunder shall
immediately terminate and be of no further force or effect, except for the
obligations of the parties which are herein expressly stated to survive the
termination of this Agreement. If Purchaser does not elect to terminate this
Agreement pursuant to this Paragraph 18, or has no right to terminate this
Agreement (because the damage or destruction does not exceed $250,000.00 and
would not give rise to a right by Tenant to terminate its Lease), and the sale
of the Property is consummated, Purchaser shall be entitled to receive all
insurance proceeds paid or payable to Seller by reason of such destruction or
damage under the insurance required to be maintained by Seller pursuant to
Paragraph 9(d) hereof (less amounts of insurance theretofore received and
applied by Seller to costs actually incurred for restoration). Seller shall not
settle or release any damage or destruction claims without obtaining Purchaser's
prior written consent in each case. All said insurance proceeds received by
Seller by the date of Closing shall be paid by Seller to Purchaser at Closing,
together with the lesser of (i) that amount necessary to cover any difference
between the amount of such proceeds and the estimated cost of repair or
replacement, or (ii) the amount of the deductible under Seller's all-risk
property damage insurance policy. In addition, at Closing, Seller shall pay over
to Purchaser, and assign to Purchaser, all proceeds of any rent loss insurance
for the period of time commencing on the date of Closing. If the amount of said
casualty or rent loss insurance proceeds is not settled by the date of Closing,
Seller shall execute at Closing all proofs of loss, assignments of claim, and
other similar instruments in order that Purchaser receive all of Seller's right,
title, and interest in and under said insurance proceeds.

         19.     Hazardous Substances. To the Seller's knowledge, and based
                 --------------------
solely on the Existing Environmental Reports (as hereinafter defined) as to
matters occurring before the Seller came into ownership of the Property, (i) no
"hazardous substances", as that term is defined in the Comprehensive
Environmental Response, Compensation, and Liability Act of 1980, as amended, 42
U.S.C. (s) 9601, et seq., the Resource Conservation and Recovery Act of 1976, as
amended, 42 U.S.C. (s) 6901, et seq., and the rules and regulations promulgated
pursuant to these acts, any so-called "super-fund" or "super-lien" laws or any
applicable state or local laws, nor any other pollutants, toxic materials, or
contaminants have been or shall prior to Closing be discharged, disbursed,
released, stored, treated, generated, disposed of, or allowed to escape on the
Property, (ii) no asbestos or asbestos containing materials have been installed,
used, incorporated into, or disposed of on the Property, (iii) no
polychlorinated biphenyls are located on or in the Property, in the form of
electrical transformers, fluorescent light fixtures with ballasts, cooling oils,
or any other device or form, (iv) no underground storage tanks are located on
the Property or were located on the Property and subsequently removed or filled,
(v) no investigation, administrative order, consent order and agreement,
litigation, or settlement with respect to hazardous substances is proposed,
threatened, anticipated or in existence with respect to the Property, and (vi)
the Property has not previously been used as a landfill, cemetery, or as a dump
for garbage or refuse. As used herein, the term "Existing Environmental Reports"
shall mean the reports and studies listed on Exhibit "T" attached hereto and by
                                             ----------
reference incorporated herein. Seller represents to Purchaser that the Existing
Environmental Reports constitute all of the environmental reports and studies
relating to the Land and Improvements obtained by Seller or any affiliate of
Seller or otherwise in the possession or control of Seller. The representations
and warranties set forth in this Paragraph 19

                                       18

<PAGE>

shall expressly survive the execution and delivery of the Special Warranty Deed
conveying the Land and Improvements from Seller to Purchaser for a period of one
(1) year after Closing whereupon they shall expire, except to the extent that
with respect to any particular alleged breach, Purchaser gives Seller written
notice prior to the expiration of said one (1) year period of such alleged
breach and files an action against Seller with respect thereto within ninety
(90) days after the giving of such notice.

         20.     Assignment. This Agreement and Purchaser's rights, duties, and
                 ----------
obligations hereunder may not be delegated, transferred, or assigned by
Purchaser without the prior written consent of Seller, and any assignee or
transferee proposed by Purchaser shall expressly assume all of Purchaser's
duties, liabilities and obligations under this Agreement by written instrument
delivered to Seller. Notwithstanding the foregoing to the contrary, this
Agreement, and Purchaser's rights and duties hereunder, may be freely assigned
and transferred to any entity under common control with Purchaser or controlled
by Purchaser or to Wells Operating Partnership, L.P., a Delaware limited
partnership, or to any partnership having Purchaser or Wells Operating
Partnership, L.P. as a direct or indirect general partner. For purposes of this
Paragraph 20, the term "control" shall mean a twenty percent (20%) ownership in
the applicable entity.

         21.     Broker's Commission. Upon the Closing, and only in the event of
                 -------------------
Closing, Seller shall pay to each of Tri-Star Properties, Inc. ("Tri-Star") and
CB Richard Ellis, Inc. ("CB") a real estate sales commission in the amount of
$80,500.00 as full and complete compensation for the services provided by
Tri-Star and CB in connection with the purchase and sale of the Property.
Tri-Star and CB each hereby agree that it shall accept the foregoing commission
amount ($80,500.00) in full and complete satisfaction of the commission payable
to it in connection with the purchase and sale of the Property and that in the
event the purchase and sale of the Property is not closed and consummated for
any reason whatsoever, then no commission shall have been earned and none shall
be payable. Seller shall and does hereby indemnify and hold harmless Purchaser
from and against any claim, whether or not meritorious, for any real estate
sales commission, finder's fees, or like compensation in connection with the
sale contemplated hereby and arising out of any act or agreement of Seller,
including any claims asserted by Tri-Star and CB. Likewise, Purchaser shall and
does hereby indemnify and hold harmless Seller from and against any claim,
whether or not meritorious, for any real estate sales commission, finder's fees,
or like compensation in connection with the sale contemplated hereby and arising
out of any act or agreement of Purchaser, except any such claims asserted by
Tri-Star and CB. This Paragraph 21 shall survive the Closing or any termination
of this Agreement.

                 -------
