               ARTICLE TWO - DISBURSEMENT OF THE REVOLVING LOAN

     2.1. Revolving Loan Facility.   Subject to all terms and conditions set
          -----------------------
forth in this Loan Agreement, Lender agrees to lend to Borrower from time to
time during the Commitment Period, upon receipt of an Advance Request from
Borrower in accordance with the procedures set forth in Section 2.3 below, such
principal sums as might be requested by Borrower for the purposes permitted in
this Loan Agreement up to a maximum principal amount at any time outstanding
equal to the Commitment Amount, provided that (i) in all events no Default or
Event of Default shall have occurred and be continuing and (ii) the outstanding
Advances shall not at any time exceed the Commitment Amount.  Within the
aforesaid limit, Borrower may borrow, make payments, and reborrow under this
Loan Agreement, subject to the provisions hereof.  Each request for an Advance
hereunder shall constitute a representation and warranty  by Borrower that all
conditions set forth in Article Three hereof have been satisfied on the date of
such request.

     2.2  Overadvances.  If notwithstanding the provisions of Section 2.1 above
          ------------
the aggregate amount of Advances outstanding under the Revolving Loan at any
time exceeds the Commitment Amount (an "Overadvance"), Borrower shall
immediately pay Lender an amount equal to the Overadvance as a payment on the
principal amount of the Revolving Loan.  The provision of this Section may be
enforced by Lender at any time and, as well as the other provisions hereof, may
not under any circumstance be waived or altered by a course of dealing or
otherwise, insofar as Borrower may request and Lender may be willing in its sole
and absolute discretion to make Overadvances.  All Overadvances shall be payable
on demand, shall be secured by the Collateral, and shall bear interest at the
rate provided in the Revolving Note.  Lender may in its sole discretion honor
any Advance Request (or deemed Advance Request) under the Revolving Loan even
though an Overadvance then exists or would exist with the making of such
Advance, and without regard to the existence of, and without waiving, any
Default or Event of Default.

<PAGE>

     2.3.   Procedures for Advances.  Whenever Borrower desires an Advance,
            -----------------------
Borrower shall give Lender prior written or telecopied notice (or telephonic
notice promptly confirmed in writing or by telecopy) of its request for such
Advance (a "Advance Request").  Any such Advance Request must be given not less
than five (5) Business Days prior to the date that Borrower desires the Advance
to be made.  Each Advance Request shall be irrevocable and shall specify the
principal amount of the Advance and the date of the Advance (which shall be a
Business Day).   Each Advance shall be accompanied by an Officer's Certificate
certifying that (i) Borrower has complied with and is in compliance with all
terms, covenants, and conditions of this Loan Agreement and the other Loan
Documents, (ii) no  Default or Event of Default exists or, if such is not the
case, that one or more specified Defaults or Events of Default have occurred,
and (iii) the representations and warranties contained in this Loan Agreement
are true with the same effect as though made on the date of such Officer's
Certificate. Each Advance shall be made at the main office of Lender in
Birmingham, Alabama (or such other place as Lender may designate) and shall be
made no more frequently that once each month.  All Advances shall be disbursed
to Borrower by depositing the same into the Loan Account.

     2.4.   Title Updates and Recording Taxes.  Prior to any Advance, Lender may
            ---------------------------------
require an endorsement to the title insurance policy insuring the lien of the
Security Instrument that extends the effective date of such policy to the date
of the Advance with no additional exceptions added to such policy.  In addition,
Lender shall be entitled to deduct and withhold from any Advance an amount equal
to any documentary stamps, intangibles tax, or other recording taxes due and
payable with respect to such Advance.

     2.5.   Security for the Revolving Loan.  The Revolving Loan shall be
            -------------------------------
secured by, and entitled to the benefits of, the Security Documents, the
Guaranty Agreement, and the other Loan Documents.

     2.6.   Interest Rate and Repayment Term.  Borrower's obligation to repay
            --------------------------------
the Revolving Loan shall be evidenced by the Revolving Note.  Interest shall
accrue on the principal amount outstanding under the Revolving Note from time to
time at the rate or rates provided in the Revolving Note.  The principal of, and
accrued interest on, the Revolving Loan shall be repaid by Borrower in
accordance with the provisions of the Revolving Note.

     2.7.   Maximum Rate.  Regardless of any provision contained in this Loan
            ------------
 Agreement or any of the Loan Documents, in no event shall the aggregate of
all amounts that are contracted for, charged, or collected pursuant to the terms
of this Loan Agreement, the Revolving Note, or any of the Loan Documents and
that are deemed interest under applicable law exceed the maximum rate permitted
by applicable law (the "Maximum Rate").  No provision of this Loan Agreement or
in any of the Loan Documents or the exercise by Lender of any right hereunder or
under any Loan Document or the prepayment by Borrower of any of the Obligations
or the occurrence of any contingency whatsoever, shall entitle Lender to charge
or receive, or to require Borrower to pay, interest or any amounts deemed
interest by applicable law (such amounts being referred to herein collectively
as "Interest") in excess of the Maximum Rate, and all provisions hereof or in
any Loan Document which may purport to require Borrower to pay Interest
exceeding the Maximum Rate shall be without binding force or effect to the
extent only of the excess of Interest over such Maximum Rate.  Any Interest
charged or received in excess of the Maximum Rate ("Excess"), shall be
conclusively presumed to be the result of an accident and bona fide error, and
shall, to the extent received by Lender, at the option of Lender, either be
applied to reduce the principal amount of the Obligations or returned to
Borrower.  All monies paid to Lender hereunder or under any of the Loan
Documents shall be subject to any rebate of unearned interest as and to the
extent required by Legal Requirements.  By the execution of this Loan Agreement,
Borrower covenants that (i) the credit or return of any Excess shall constitute
the acceptance by Borrower of such Excess, and (ii) Borrower shall not seek or
pursue any other remedy, legal or equitable, against Lender, based in whole or
in part upon contracting for, charging, or receiving any Excess, provided that
such Excess has been refunded or credited to the benefit of Borrower.  For the
purpose of determining whether or not any Excess has been contracted for,
charged, or received by Lender, all Interest at any time contracted for,
charged, or received from Borrower in connection with this Loan Agreement shall,
to the extent permitted by applicable law, be amortized, prorated, allocated,
and spread in equal parts throughout the full term of the Obligations.  Borrower
and Lender shall, to the maximum extent permitted under applicable law, (i)
characterize any non-

principal payment as an expense, fee, or premium rather than as Interest and
(ii) exclude voluntary prepayments and the effects thereof. The provisions of
this Section shall be deemed to be incorporated into the Revolving Note and each
Loan Document (whether or not any provision of this Section is referred to
therein).

     2.8  Advance Fee.  Concurrently with the making of any Advance by Lender to
          -----------
Borrower, Borrower shall pay to Lender a fee in the amount equal to 0.125% of
the Advance amount (each an "Advance Fee").  Each Advance Fee (i) shall be
deemed fully earned at the time the Advance is made  and (ii) shall not be
subject to refund or rebate under any circumstance whatsoever.  The Advance Fee
is intended to compensate Lender for the costs associated with the
administration, processing, and closing of each Advance, including, but not
limited to, administrative and general overhead, but not including any out-of-
pocket or other expenses for which Borrower has agreed to reimburse Lender
pursuant to any other provisions of this Loan Agreement or any of the Loan
Documents.

                 ARTICLE FOUR - REPRESENTATIONS AND WARRANTIES

     4.1  Representations and Warranties Regarding Borrower Parties.  Borrower
          ---------------------------------------------------------
represents and warrants to Lender that:

          4.1.1 Due Organization and Qualification. Borrower is a
                ----------------------------------
     limited liability company duly organized, validly existing, and
     in good standing under the laws of the state of its formation as
     set forth in the heading of this Loan Agreement and is qualified
     to transact business and is in good standing in the state in
     which the Project is located and in each other jurisdiction where
     the failure to be so qualified and to be in good standing would
     adversely affect the conduct of its business or the validity of,
     the enforceability of, or the ability of Borrower to perform, the
     Obligations.

          4.1.2 Power and Authority.  Borrower has the requisite power
                -------------------
     and authority to (i) to own the Project and to carry on its
     business as now conducted and as contemplated to be conducted in
     connection with the performance of the Obligations hereunder and
     under the other Loan Documents and (ii) to execute and deliver
     this Loan Agreement and the other Loan Documents, to incur and
     perform the Obligations, and to carry out the transactions
     contemplated by this Loan Agreement and the other Loan Documents.

          4.1.3 Due Authorization.  The execution, delivery, and
                -----------------
     performance of this Loan Agreement and the other Loan Documents
     have been duly authorized by all necessary action and proceedings
     by or on behalf of Borrower, and no further approvals or filings
     of any kind, including any approval of or filing with any
     Governmental Authority, are required by or on behalf of Borrower
     as a condition to the valid execution, delivery, and performance
     by Borrower of this Loan Agreement and the other Loan Documents.

          4.1.4 Enforceability.  This Loan Agreement and each of the
     other Loan Documents have been duly authorized, executed, and
     delivered by Borrower and constitute the legal, valid, and
     binding obligation of Borrower, enforceable against Borrower in
     accordance with their respective terms, except

________________________________________________________________________________
                                   Amended and Restated Loan Agreement - Page 10
                                    Wells REIT, LLC - VA I (ABB Office Building)
<PAGE>

     as such enforceability may be affected by applicable conservatorship,
     bankruptcy, insolvency, reorganization, moratorium, or similar laws
     affecting the enforcement of creditors' rights generally. This Loan
     Agreement and the other Loan Documents are not subject to any right of
     rescission, set-off, counterclaim, or defense by Borrower, including
     the defense of usury, and Borrower has not asserted any right of
     rescission, set-off, counterclaim, or defense with respect thereto.

          4.1.5  No Conflicts.  Neither the execution and delivery of this
                 ------------
     Loan Agreement and the other Loan Documents, nor the fulfillment of or
     compliance with the terms and conditions of this Loan Agreement and
     the other Loan Documents, nor the performance of the Obligations (i)
     conflicts with or result in (or will conflict with or result in) any
     breach or violation of any Legal Requirement enacted or issued by any
     Governmental Authority or other agency having jurisdiction over
     Borrower or the Project, or any judgment or order applicable to
     Borrower, or to which Borrower or the Project is subject; (ii)
     conflicts with or result in (or will conflict with or result in) any
     material breach or violation of, or constitute a default under, any of
     the terms, conditions, or provisions of Borrower's organizational
     documents, any indenture, existing agreement, or other instrument to
     which Borrower is a party, or to which Borrower or the Project is
     subject; (iii) results in or requires (or will result in or require)
     the creation of any lien on all or the Project, except for the
     Permitted Encumbrances; or (iv) requires (or will require) the consent
     or approval of any creditor of Borrower, any Governmental Authority,
     or any other Person except such consents or approvals that have
     already been obtained.

          4.1.6  Pending Litigation or other Proceedings.  There is no
                 ---------------------------------------
     pending or, to the best knowledge of Borrower, threatened action,
     suit, proceeding, or investigation, at law or in equity, before any
     court, board, body, or official of any Governmental Authority or
     arbitrator against or affecting the Project or any other portion of
     the Collateral or other assets of Borrower, which, if decided
     adversely to Borrower, would have, or may reasonably be expected to
     have, a Material Adverse Effect. Borrower is not in default with
     respect to any order of any Governmental Authority.

          4.1.7  Solvency.  Borrower is not insolvent and will not be
                 --------
     rendered insolvent by the transactions contemplated by this Loan
     Agreement or the other Loan Documents, and after giving effect to such
     transactions, Borrower will not be left with an unreasonably small
     amount of capital with which to engage in its business or
     undertakings, nor will Borrower have incurred, have intended to incur,
     or believe that it has incurred, debts beyond its ability to pay such
     debts as they mature. Borrower did not receive less than a reasonably
     equivalent value in exchange for incurrence of the Obligations. There
     (i) is no contemplated, pending or, to the best of Borrower's
     knowledge, threatened bankruptcy, reorganization, receivership,
     insolvency, or like proceeding, whether voluntary or involuntary,
     affecting any Borrower Party or the Project and (ii) has been no
     assertion or exercise of jurisdiction over any Borrower Party or the
     Project by any court empowered to exercise bankruptcy powers.

          4.1.8  No Contractual Defaults.  There are no defaults by
                 -----------------------
     Borrower or, to the knowledge of Borrower, by any other Person under
     any contract to which Borrower is a party relating to the Project,
     including any management, rental, service, supply, security,
     maintenance, or similar contract, other than defaults which do not
     permit the non-defaulting party to terminate the contract and which do
     not have, and are not reasonably be expected to have, a Material
     Adverse Effect. Neither Borrower nor, to the knowledge of Borrower,
     any other Person, has received notice or has any knowledge of any
     existing circumstances in respect of which it could receive any notice
     of default or breach in respect of any contracts affecting or
     concerning the Project.

<PAGE>

          4.1.9   Compliance with the Loan Documents. Borrower is in
                  ----------------------------------
     compliance with all provisions of the Loan Documents to which it is a
     party or by which it is bound. The representations and warranties made
     by Borrower in the Loan Documents are true, complete and correct and
     do not contain any untrue statement of material fact or omit to state
     a material fact required to be stated therein or necessary in order to
     make the statements made therein, in light of the circumstances under
     which they were made, not misleading.

          4.1.10  Non-Foreign Person.  Borrower is not a "foreign person"
                  ------------------
     within the meaning of (S) 1445(f)(3) of the Internal Revenue Code.

          4.1.11  ERISA.  Neither Borrower nor Wells REIT has established
                  -----
     and is a party to an "employee benefit plan" within the meaning of
     Section 3(3) of Employee Retirement Income Security Act of 1974, as
     amended from time to time ("ERISA"), or any other option or deferred
     compensation plan or contract for the benefit of its employees or
     officers, pension, profit sharing or retirement plan, redemption
     agreement, or any other agreement or arrangement with any officer,
     director or owner, members of their families, or trusts for their
     benefit, and the assets of Borrower do not and shall not constitute
     "plan assets" of one more such plans for purposes of ERISA.

          4.1.12  Ownership.  The ownership of all interests in Borrower
                  ---------
     have been accurately disclosed to Lender in writing. Except for
     warrants that have been issued to some of the directors of Wells REIT,
     there are no outstanding warrants, options, or rights to purchase any
     ownership interests of Borrower, nor does any Person have a lien upon
     any of the ownership interests of Borrower.

          4.1.13  Investment Company Act.  Borrower is not (i) an
                  ----------------------
     "investment company" or a company "controlled" by an "investment
     company," within the meaning of the Investment Company Act of 1940, as
     amended, (ii) a "holding company" or a "subsidiary company" of a
     "holding company" or an "affiliate" of either a "holding company" or a
     "subsidiary company" within the meaning of the Public Utility Holding
     Company Act of 1935, as amended, or (iii) subject to any other federal
     or state law or regulation that purports to restrict or regulate its
     ability to borrow money.

          4.1.14  Financial Information.  The financial projections
     relating to Borrower and delivered to the Lender on or prior to the
     date hereof, if any, were prepared on the basis of assumptions
     believed by Borrower, in good faith at the time of preparation, to be
     reasonable, and Borrower is not aware of any fact or information that
     would lead it to believe that such assumptions are incorrect or
     misleading in any material respect; provided, however, that no
     representation or warranty is made that any result set forth in such
     financial projections shall be achieved. The financial statements of
     Borrower and any Rent Roll for the Project which have been furnished
     to Lender are complete and accurate in all material respects and
     present fairly the financial condition of Borrower and the leasing
     status of the Project, and there are no liabilities, direct or
     indirect, fixed or contingent, as of the respective dates of such
     financial statements which are not reflected therein or in the notes
     thereto or in a written certificate delivered with such statements.
     The financial statements of Borrower have been prepared in accordance
     with GAAP. Since the date of the most recent of such financial
     statements, no event has occurred which would have, or may reasonably
     be expected to have, a Material Adverse Effect, and there has not been
     any material transaction entered into by Borrower other than
     transactions in the ordinary course of business. Borrower has filed
     all federal, state, and local tax returns that are required to be
     filed and has paid, or made adequate provision for the payment of, all
     taxes that have or may become due pursuant to such returns or to
     assessments received by Borrower.

<PAGE>

          4.1.15  Accuracy of Information.  No information, statement, or
                  -----------------------
     report furnished in writing to Lender by Borrower in connection with
     this Loan Agreement or any other Loan Document, or in connection with
     the consummation of the transactions contemplated hereby and thereby,
     contains any material misstatement of fact or omits to state a
     material fact necessary to make the statements contained therein, in
     light of the circumstances under which they were made, not misleading.

          4.1.16  No Conflicts of Interest.  To the best knowledge of
                  ------------------------
     Borrower, no officer, agent, or employee of Lender has been or is in
     any manner interested, directly or indirectly, in that Person's own
     name, or in the name of any other Person, in the Loan Documents,
     Borrower, or the Project, in any contract for property or materials to
     be furnished or used in connection with the Project, or in any aspect
     of the transactions contemplated by the Loan Documents.

          4.1.17  No Reliance.  Borrower acknowledges, represents, and
                  -----------
     warrants that it understands the nature and structure of the
     transactions contemplated by this Loan Agreement and the other Loan
     Documents, that it is familiar with the provisions of all of the
     documents and instruments relating to such transactions, that it
     understands the risks inherent in such transactions, including the
     risk of loss of the Collateral or a part thereof, and that it has not
     relied on Lender for any guidance or expertise in analyzing the
     financial or other consequences of the transactions contemplated by
     this Loan Agreement or any other Loan Document or otherwise relied on
     Lender in any manner in connection with interpreting, entering into,
     or otherwise in connection with this Loan Agreement, any other Loan
     Document, or any of the matters contemplated hereby or thereby.

          4.1.18  Contracts with Affiliates.  Except as otherwise approved
                  -------------------------
     in writing by Lender, Borrower has not entered into and is not a party
     to any contract, lease, or other agreement with any Affiliate of
     Borrower for the provision of any service, materials, or supplies to
     the Project (including any contract, lease, or agreement for the
     provision of property management services (other than the Management
     Agreement), cable television services or equipment, gas, electric or
     other utilities, security services or equipment, laundry services or
     equipment or telephone services or equipment).

          4.1.19  Lines of Business.  Borrower is not engaged in any
                  -----------------
     businesses other than the acquisition, ownership, development,
     construction, leasing, financing, or management of commercial
     properties, and the conduct of these businesses does not violate the
     organizational documents pursuant to which it is formed.

     4.2  Representations and Warranties Regarding the Project. Borrower
          ----------------------------------------------------
represents and warrants to Lender that, as of the Closing Date with respect
to the Project as of the Closing Date:

          4.2.1   Title.  Borrower has good, valid, marketable, and
     indefeasible title to the Land, free and clear of all liens whatsoever
     except the Permitted Encumbrances. The Security Instrument, if and
     when properly recorded in the appropriate records, together with any
     Uniform Commercial Code financing statements required to be filed in
     connection therewith, will create a valid, perfected first lien on the
     Collateral intended to be encumbered thereby (including the Leases and
     the rents and all rights to collect rents under such Leases), subject
     only to Permitted Encumbrances. Except for any Permitted Encumbrances,
     there are no lens or claims for work, labor, or materials affecting
     the Land that are or may be prior to, subordinate to, or of equal
     priority with, the liens created by the Loan Documents. The Permitted
     Encumbrances do not have, and may not reasonably be expected to have,

     or on public or utility easements for the (i) fulfillment of any
     zoning, building code, or other requirement of any Governmental
     Authority that has jurisdiction over the Project, (ii) structural
     support, or (iii) the fulfillment of the requirements of any Lease or
     other agreement affecting such Project. Borrower, directly or
     indirectly, has the right to use all amenities, easements, public or

     currently used for the operation of the Project. All public utilities
     are installed and operating at the Project, and all billed
     installation and connection charges have been paid in full. The
     Project is either (x) contiguous to or (y) benefits from an
     irrevocable unsubordinated easement permitting access from the Project
     to a physically open, dedicated public street, and has all necessary
     permits for ingress and egress and is adequately serviced by public
     water, sewer systems, and utilities. No building or other improvement
     not located on the Project relies on any part of the Project to

     for structural support or to furnish to such building or improvement
     any essential building systems or utilities.

     is in good condition, order, and repair, there exist no structural or
     other material defects in the Project (whether patent or, to the best
     knowledge of Borrower, latent or otherwise), and Borrower has not
     received notice from any insurance company or bonding company of any
     defects or inadequacies in the Project, or any part of it, which would
     adversely affect the insurability of the Project or cause the
     imposition of extraordinary premiums or charges for insurance, or of
     any termination or threatened termination of any policy of insurance
     or bond. No claims have been made against any contractor, architect,
     or other party with respect to the condition of the Project or the
     existence of any structural or other material defect therein. The
     Project has not been materially damaged by casualty which has not been
     fully repaired or for which insurance proceeds have not been received
     or are not expected to be received except as previously disclosed in
     writing to Lender. No proceedings are pending or, to the best of
     Borrower's knowledge, threatened to acquire by power of condemnation

          5.2.3  Legal Requirements.  Borrower shall comply with all Legal
                 ------------------

     generality of the foregoing covenant, Borrower specifically agrees that the
     Project shall at all times strictly comply, to the extent applicable, with
     the requirements of the Americans with Disabilities Act of 1990, all state
     and local laws and ordinances related to handicapped access and all rules,
     regulations, and orders issued pursuant thereto including, without
     limitation, the Americans with Disabilities Act Accessibility Guidelines
     for Buildings and Facilities (collectively "Access Laws").  Notwithstanding
     any provisions set forth herein or in any other document regarding Lender's
     approval of alterations of the Project, Borrower shall not alter or permit
     the Project to be altered in any manner which would increase Borrower's
     responsibilities for compliance with the applicable Access Laws without the

     upon receipt of a certificate of Access Law compliance from an architect,
     engineer, or other person acceptable to Lender.  Borrower agrees to give
     prompt notice to Lender of the receipt by Borrower of any complaints
     related to violation of any Access Laws and of the commencement of any

     while the Obligations remain outstanding, to enter upon and appraise the
     Project, and Borrower shall cooperate with and provide any information
     requested in connection with such appraisal.  Borrower shall pay the costs
     of any such appraisal (i) if an Event of Default has occurred and is
     continuing or (ii) if such appraisal is required by external regulatory
     authorities having jurisdiction over Lender.

          5.2.5  Conduct of Business.  Borrower shall cause the operation of the
                 -------------------
     Project to be conducted at all times in a manner consistent with the level

     foregoing, Borrower shall (i) operate the Project in a prudent manner in
     compliance with Legal Requirements, (ii) maintain sufficient equipment and
     supplies of types and quantities at the Project to enable Borrower or
     Manager adequately to perform the operation of the Project and Borrower's

                 ------
     obligations imposed upon Borrower under the ABB Lease and shall not do or

     guaranty of the ABB Lease, if any,  as a security for the Obligations, (ii)
     shall promptly send copies to Lender of all notices of default which
     Borrower shall send or receive under the ABB Lease, and (iii) shall enforce
     all of the terms, covenants, and conditions contained in the ABB Lease upon
     the part of Tenant thereunder to be observed or performed (other than any
     enforcement action with respect to which Lender's prior written consent

     material respect, or cancel or terminate the ABB Lease or accept a
     surrender thereof, convey or transfer or suffer or permit a conveyance or

     Lease), and (cc) shall not pursue any remedies under the ABB Lease.

          5.2.7  Management Agreement.  Borrower shall maintain the Management
                 --------------------

     all obligations of Manager thereunder. Borrower shall promptly notify
     Lender of any dispute, default, event of default, or repudiation by Manager
     under the Management Agreement.  Borrower shall not enter into any
     management agreement for the Project other than the Management Agreement,
     unless Borrower first notifies Lender and provides Lender a copy of the
     proposed management agreement, obtains Lender's written consent thereto and
     obtains and provides Lender with a subordination agreement in form
     satisfactory to Lender from such manager subordinating to all rights of
     Lender.  Borrower shall not enter into, terminate, amend, modify, or extend
     the Management Agreement, or consent to any such action on the part of
     Manager, without the prior written consent of Lender, which consent shall
     not be unreasonably withheld.

          5.2.8  Ownership of Personalty.  Borrower shall furnish to Lender, if
                 -----------------------
     Lender so requests, the contracts, bills of sale, receipted vouchers, and
     agreements, or any of them, under which Borrower claims title to the
     materials, articles, fixtures, and other personal property used or to be
     used in the construction or operation of the Improvements.

             ARTICLE SIX - PROHIBITION ON TRANSFERS OF COLLATERAL

     6.1  General Prohibition.  Borrower acknowledges that Lender has examined
          -------------------
and relied on the experience of Borrower and the owners of the beneficial
interest in Borrower and Borrower's constituent entities in owning and operating
the Project in agreeing to make the Loan, and that Lender will continue to rely
on Borrower's ownership of the Project as a means of maintaining the value of
the Collateral as security for repayment of the Obligations.  Borrower
acknowledges that Lender has a valid interest in maintaining the value of the
Project so as to ensure that, should Borrower default in the repayment of the
Obligations, Lender can recover all or a portion of the Obligations by a sale of
the Collateral.  Except as expressly provided herein, Lender may, at Lender's
option, declare all the Obligations immediately due and payable, and Lender may
invoke any rights and remedies permitted by this Loan Agreement and the other
Loan Documents, in the event that Borrower, without the prior written consent of
Lender, which consent may not be unreasonably withheld by Lender after
consideration of all relevant factors, sells, conveys, alienates, mortgages,
encumbers, pledges, or otherwise transfers the Collateral or any part thereof or
any interest therein, or permits the Collateral or any part thereof or any
interest therein to be sold, conveyed, alienated, mortgaged, encumbered, pledged
or otherwise transferred (collectively, a "Transfer").

     6.2  Transactions Included. A Transfer within the meaning of Section 6.1
          ---------------------
shall be deemed to include, without limitation, (i) an installment sales
agreement wherein Borrower agrees to sell the Collateral or any part thereof

for a price to be paid in installments; (ii) an agreement by Borrower leasing
all or a substantial part of the Project for other than actual occupancy by a
space lessee thereunder or a sale, assignment or other transfer of, or the grant
of a security interest in, Borrower's right, title and interest in and to the
Leases or any rents therefrom; (iii) any divestiture of Borrower's title to the
Collateral or any interest therein in any manner or way, whether voluntary or
involuntary, or any merger, consolidation, dissolution or syndication affecting
Borrower; (iv) if Borrower or any general partner of Borrower is a corporation,
the voluntary or involuntary sale, conveyance, or transfer of any of such
corporation's stock or the creation or issuance of new stock in one or a series
of transactions by which an aggregate of more than ten percent (10%) of such
corporation's stock shall be vested in an Acquiring Person who is not now a
stockholder of such corporation or any change in the control of such corporation
directly or indirectly; (v) if Borrower or any general partner of Borrower is a
limited or general partnership, joint venture, or limited liability company, the
change, removal, resignation, or addition of a general partner, managing
partner, limited partner, joint venturer, manager, or member, or the transfer of
any partnership interest of any general partner, managing partner, or limited
partner, or the transfer of any interest of any joint venturer or member (or the
transfer of any interest of any Person directly or indirectly controlling such
partner, joint venturer, or member by operation of law or otherwise) to an
Acquiring Person; and (vi) if Borrower or any general partner of Borrower is a
business trust, the change, removal, resignation, or addition of a trustee, or
the voluntary or involuntary sale, conveyance, or transfer of any beneficial
interest.

          -------------------
above, the following Transfers are permitted without the consent of Lender:

          6.3.1  The Transfer of shares of common stock or other beneficial or
     ownership interest or other forms of securities in Wells REIT, and the
     issuance of all varieties of convertible debt, equity and other similar
     securities of Wells REIT and the subsequent Transfer of such securities,
     provided that no Change in Control occurs as a result of such Transfer,
     either upon such Transfer or upon the subsequent conversion to equity or
     such convertible debt or other securities.

          6.3.2  The Transfer of the ownership interests by the members of

     securities.

          6.3.4  A sale or other disposition of obsolete or worn out personal
     property, provided that such personal property is contemporaneously
     replaced by comparable personal property of equal or greater value that is
     free and clear of liens other than the Permitted Encumbrances.

          6.3.5  Any Transfer that constitutes a Permitted Encumbrance at the
     time such Transfer occurs.

          6.3.6   The grant of an easement, if prior to the granting of the
     easement Borrower causes to be submitted to Lender all information required
     by Lender to evaluate the easement, and if Lender determines that the
     easement shall not materially affect the operation of the Project or
     Lender's interest in the Project and Borrower pays to Lender, on demand,
     all cost and expenses incurred by Lender in connection with reviewing
     Borrower's request.

of a Transfer without Lender's prior written consent or as otherwise expressly
permitted herein.  This provision shall apply to every Transfer regardless of
whether voluntary or not, or whether or not Lender has consented to any previous

     reasonable extension of such cure period, but not exceeding ninety (90)
     days; or

           7.1.13  If an "Event of Default" occurs under any Lease, which
     default remains uncured after the giving of any applicable notice or the
     passage of any applicable cure period, or any Lease is terminated,

     7.2   Remedies.  Upon the occurrence of an Event of Default, Lender may do
           --------
any one or more of the following (without presentment, protest or notice of
protest, all of which are expressly waived by the Borrower):

           7.2.1   By written notice to the Borrower, to be effective upon
     dispatch, terminate any obligation Lender might have to make further
     Advances hereunder and declare the principal of, and interest on, the

     Loan Documents forthwith due and payable, and the principal of, and
     interest on, the Advances and all other sums owing by Borrower to Lender
     under any of the Loan Documents will become forthwith due and payable.

           7.2.2   Lender shall have the right to pursue any other remedies
     available to it under any of the Loan Documents.

           7.2.3   Lender shall have the right to pursue all remedies available

     injunctive relief.

     7.3   Waivers; Rescission of Declaration.   Lender shall have the right, to
           ----------------------------------
be exercised in its complete discretion, to waive any breach hereunder
(including the occurrence of an Event of Default), by a writing setting forth
the terms, conditions, and extent of such waiver signed by the Lender and
delivered to the Borrower Parties.  Unless such writing expressly provides to
the contrary, any waiver so granted shall extend only to the specific event or
occurrence which gave rise to the waiver and not to any other similar event or
occurrence which occurs subsequent to the date of such waiver.

     7.4   Lender's Right to Protect Collateral and Perform Covenants and Other
           --------------------------------------------------------------------
Obligations.  If any Borrower Party fails to perform the covenants and
-----------
agreements contained in this Loan Agreement or any of the other Loan Documents,
then the Lender at the Lender's option may make such appearances, disburse such
sums and take such action as the Lender deems necessary, in its sole discretion,
to protect the Lender's interest, including (i) disbursement of attorneys' fees,
(ii) entry upon the Project to make repairs and replacements, (iii) procurement
of satisfactory insurance as provided in the Security Instruments encumbering
the Project, and (iv) if the Security Instrument is on a leasehold, exercise of
any option to renew or extend the ground lease on behalf of the Borrower and the
curing of any default of the Borrower in the terms and conditions of the ground
lease.  Any amounts disbursed by the Lender pursuant to this Section, with
interest thereon, shall become additional indebtedness of the Borrower secured
by the Loan Documents.  Unless the Borrower and the Lender agree to other terms
of payment, such amounts shall be immediately due and payable and shall bear
interest from the date of disbursement at the Default Rate unless collection
from the Borrower of interest at such rate would be contrary to applicable law,
in which event such amounts shall bear interest at the highest rate which may be
collected from the Borrower under applicable law.  Nothing contained in this
Section shall require the Lender to incur any expense or take any action
hereunder.

     7.5   No Remedy Exclusive.  Unless otherwise expressly provided, no remedy
           -------------------
herein conferred upon or reserved is intended to be exclusive of any other
available remedy, but each remedy shall be cumulative and shall be in addition
to other remedies given under the Loan Documents or existing at law or in
equity.

     7.6  Application of Payments.  Except as otherwise expressly provided in
          -----------------------
the Loan Documents, and unless applicable law provides otherwise, (i) all
payments received by Lender from any of the Borrower Parties under the Loan
Documents shall be applied by Lender against any amounts then due and payable
under the Loan Documents by any of the Borrower Parties, in any order of
priority that the Lender may determine and (ii) the Borrower shall have no right
to determine the order of priority or the allocation of any payment it makes to
Lender.

     7.7  Crossing of Security Documents.  Each of the Security Documents shall
          ------------------------------
be cross-defaulted (i.e., a default under any Security Document, or under this
Loan Agreement, shall constitute a default under each Security Document and this
Loan Agreement) and cross-collateralized (i.e., each Security Instrument shall
secure all Obligations under this Loan Agreement and the other Loan Documents),
and it is the intent of the parties to this Loan Agreement that the Lender may,
except as provided in this Loan Agreement, exercise and perfect any and all of
its rights in and under the Loan Documents with regard to the Project without
the necessity to exercise and perfect its rights and remedies with respect to
any other Project and that any such exercise shall be without regard to the
amount of Advances allocable to such Project and that Lender may recover an
amount equal to the full amount of the outstanding Obligations in connection
with such exercise and any such amount shall be applied as determined by Lender
in its sole and absolute discretion.

this Loan Agreement shall control.

(x) the enforcement by any Indemnified Party of the provisions of this Section,
(xi) the payment of any commission, charge or brokerage fee to anyone which may

this Section shall become immediately due and payable and shall bear interest at
the Default Rate from the date loss or damage is sustained by Lender until paid.
For purposes of this Section, the term "Indemnified Parties" shall mean Lender
and any Person who is or shall have been involved in the origination or
administration of the Loan, any Person in whose name the encumbrance created by
the Security Documents is or shall have been recorded, Persons who may hold or
acquire or shall have held a full or partial interest in the Revolving
Loan(including, but not limited to Investors or prospective investors who hold
or have held a full or partial interest in the Revolving Loan for the benefit of
third parties) as well as the respective directors, officers, shareholders,
members, partners, employees, agents, servants, representatives, contractors,
subcontractors, affiliates, subsidiaries, participants, successors and assigns
of any other Person who holds or acquires or shall have held a participation or
other full or partial interest in the Revolving Loan or any Project, whether
during the term of the Revolving Loan or as a part of or following a foreclosure
of the Revolving Loan and including, but not limited to any successors by
merger, consolidation or acquisition of all or a substantial portion of Lender's
assets and business.

     8.3   Costs and Expenses.  Borrower shall bear all taxes, fees, and
           ------------------
expenses (including reasonable fees and expenses of counsel for Lender) in
connection with the Loan, the Revolving Note, the preparation and, if
applicable, the recordation of this Loan Agreement and the other Loan Documents,
and in connection with any amendments, waivers, or consents pursuant to the
provisions hereof hereafter made and any workout or restructuring relating  to
the Loan.  If, at any time, an Event of Default occurs or Lender becomes a party
to any suit or proceeding in order to protect its interests or priority in the
Project or its rights under this Loan Agreement or any of the other Loan
Documents, or if Lender is made a party to any suit or proceeding by virtue of
the Loan, this Loan Agreement, or the Project and as a result of any of the
foregoing, Lender employs counsel to advise or provide other representation with
respect to this Loan Agreement, the Project, or to collect the Obligations, or
to take any action in or with respect to any suit or proceeding relating to this
Loan Agreement, any of the other Loan Documents, the Project, Borrower, or any
other Borrower Party, or to protect, collect, or liquidate any of the
Collateral, or attempt to enforce any security interest or lien granted to
Lender by any of the Loan Documents, then in any such event, all of the
attorney's fees arising from such services, including fees on appeal and in any
bankruptcy proceedings, and any expenses, costs, and charges relating thereto
shall constitute additional obligations of Borrower to Lender payable on demand
of Lender.  Without limiting the foregoing, Borrower has undertaken the
obligation for payment of, and shall pay, all recording and filing fees, revenue
or documentary stamps or taxes, intangibles taxes, transfer taxes, recording
taxes and other taxes, expenses and charges payable in connection with this Loan
Agreement, any of the other Loan Documents, the Obligations, or the filing of
any financing statements or other instruments required to effectuate the
purposes of this Loan Agreement, and if Borrower fails to do so, Borrower agrees
to reimburse Lender for the amounts paid by Lender, together with penalties or
interest, if any, incurred by Lender as a result of underpayment or nonpayment.
This Section shall survive for eighteen (18) months after repayment of the
Obligations.

     8.3   Assignability.  Neither this Loan Agreement, nor any rights or
           -------------
obligations hereunder, nor any Advance to be made hereunder, is assignable by
Borrower.  The rights of Lender under this Loan Agreement are assignable in part
or wholly and any assignee of Lender shall succeed to and be possessed of the
rights of Lender hereunder to the extent of the assignment made, including the
right to make Advances to Borrower or any approved assignee of Borrower in
accordance with this Loan Agreement.

     8.4   Relationship of the Parties.  Borrower agrees that its relationship
           ---------------------------
with Lender is solely that of debtor and creditor.  Nothing contained in this
Loan Agreement or in any other Loan Document shall be deemed to create a
partnership, tenancy-in-common, joint tenancy, joint venture, or co-ownership by
or between Borrower and Lender, or

make Lender the agent or representative of Borrower. Lender shall not be in any
way liable or responsible for any debts, losses, obligations, or duties of
Borrower with respect to the Project or otherwise, including, without
limitation, any debts, obligations, or duties owed at any time to materialmen,
contractors, craftsmen, laborers, or others for goods delivered to or services
performed by them in relation to the Project, it being understood that no
contractual relationship, either expressed or implied, exists between Lender and
any materialmen, subcontractors, craftsmen, laborers, or any other person
supplying any work, labor, or materials for the Project. Borrower, at all times
consistent with the terms and provisions of this Loan Agreement and the other
Loan Documents, shall be free to determine and follow its own policies and
practices in the conduct of its business.

     8.5  Participation.  Borrower acknowledges and agrees that Lender may, at
          -------------
its option, sell participation interests in the Revolving Loan to other
participating lenders, provided, however, that Borrower shall continue to be
entitled to deal with Lender as though no such participations had been sold.
Borrower agrees with all present and future such participants that if an Event
of Default occurs, each participant shall have all of the rights and remedies of
Lender with respect to any deposit due from any participant to Borrower,
including, without limitation, the right to set off such deposits against
Borrower's obligations hereunder.  The execution by a participant of a
participation agreement with Lender and the execution by Borrower of this Loan
Agreement, regardless of the order of execution, with a copy to Borrower, shall
evidence an agreement between Borrower and such participant in accordance with
the terms hereof.

                       ARTICLE NINE - DOCUMENT PROTOCOLS

     This Loan Agreement and each of the other Loan Documents shall be governed
by the following protocols (the "Document Protocols"), unless any Loan Document
expressly states that the Document Protocols shall not apply to such Loan
Document in whole or in part:

          ----------------------
Loan Document as from time to time amended, modified, replaced, restated,
extended or supplemented, including by waiver or consent, and to all attachments

Any party may change the address to which any notice is to be delivered to any
other address within the United States of America by furnishing written notice
of such change at least fifteen (15) days prior to the effective date of such
change to the other parties in the manner set forth above, but no such notice of
change shall be effective unless and until received by such other parties.
Rejection or refusal to accept, or inability to deliver because of changed
address or because no notice of changed address was given, shall be deemed to be
receipt of any such notice.  Any notice to an entity shall be deemed to be given
on the date specified in this Section without regard to when such notice is
delivered by the entity to the individual to whose attention it is directed and
without regard to the fact that proper delivery may be refused by someone other
than the individual to whose attention it is directed.  If a notice is received
by an entity, the fact that the individual to whose attention it is directed is
no longer at such address or associated with such entity shall not affect the
effectiveness of such notice.  Notices may be given on behalf of any party by
such party's attorneys.

     9.3  Severability.  Whenever possible, each provision of such Loan Document
          ------------
shall be interpreted in such a manner as to be effective and valid under
applicable law, but if any provision of such Loan Document shall be prohibited
by or invalid or unenforceable under the applicable law of any jurisdiction with
respect to any Person or circumstance, such provision shall be ineffective to
the extent of such prohibition, invalidity or unenforceability, without
invalidating the remaining provisions of such Loan Document or affecting the
validity or enforceability of such provisions in any other jurisdiction or with
respect to other Persons or circumstances.  To the extent permitted by
applicable law, the parties to such Loan Document thereby waive any provision of
law that renders any provision thereof prohibited, invalid or unenforceable in
any respect.

<PAGE>

     9.4  Remedies Not Exclusive.  No remedy therein conferred upon or reserved
          ----------------------
to Lender is intended to be exclusive of any other remedy or remedies available
to Lender under such Loan Document, at law, in equity or by statute, and each
and every such remedy shall be cumulative and in addition to every other remedy
given thereunder or now or hereafter existing at law, in equity or by statute.

     9.5  Liability.  If Borrower or Guarantor consists of more than one Person,
          ---------
the obligations and liabilities of each such Person under such Loan Document
shall be joint and several, except as expressly provided to the contrary in such
Loan Document.

     9.6  Binding Obligations; Covenants Run with the Land.  Such Loan Document
          ------------------------------------------------
shall be binding upon Borrower or Guarantor, as the case may be, and the
successors, assigns, heirs and personal representatives of Borrower or
Guarantor, as the case may be, and shall inure to the benefit of Lender and all
subsequent holders of such Loan Document and their respective officers,
directors, employees, shareholders, agents, successors and assigns.  Nothing in
such Loan Document, whether express or implied, shall be construed to give any
Person (other than the parties thereto and their permitted successors and
assigns and as expressly provided therein) any legal or equitable right, remedy
or claim under or in respect of such Loan Document or any covenants, conditions
or provisions contained therein.  If such Loan Document is to be recorded, all
of the grants, covenants, terms, provisions, covenants and conditions of such
Loan Document shall run with the land.

     9.7  No Oral Modifications.  Such Loan Document, and any of the provisions
          ---------------------
thereof, cannot be altered, modified, amended, waived, extended, changed,
discharged or terminated orally or by any act on the part of Borrower,
Guarantor, or Lender, but only by an agreement in writing signed by the party
against whom enforcement of any alteration, modification, amendment, waiver,
extension, change, discharge or termination is sought.  Without limiting the
generality of the foregoing, any payment made by Lender for insurance premiums,
impositions or any other charges affecting the Project shall not constitute a
waiver of Borrower's or any Guarantor's default in making such payments and
shall not obligate Lender to make any further payments.

     9.8  Entire Agreement.  Such Loan Document, together with the other
          ----------------
applicable Loan Documents, constitutes the entire agreement of the parties
thereto with respect to the subject matter thereof and supersedes all prior
written and oral agreements and understandings with respect to such subject
matter.

     9.9  Waiver of Acceptance.  Borrower and Guarantor hereby waive any
          --------------------
acceptance of such Loan Document by Lender in writing, and such Loan Document
shall immediately be binding upon Borrower or Guarantor, as the case may be.

     9.10 Jurisdiction, Court Proceedings.  Each of Lender, Borrower, and
          -------------------------------
Guarantor, to the fullest extent permitted by law, hereby knowingly,
intentionally, and voluntarily, with and upon the advice of competent counsel,
(i) submits to personal, nonexclusive jurisdiction in the State of Georgia with
respect to any suit, action, or proceeding by any person arising from, relating
to, or in connection with such Loan Document or the Loan, (ii) agrees that any
such suit, action, or proceeding may be brought in any state or federal court of
competent jurisdiction sitting in the State of Georgia, and (iii) submits to the
jurisdiction of such courts.  Each of Borrower and Guarantor, to the fullest
extent permitted by law, hereby knowingly, intentionally, and voluntarily, with
and upon the advice of competent counsel, further agrees that it shall not bring
any action, suit, or proceeding in any forum other than in the state or federal
courts of the State of Georgia (but nothing herein shall affect the right of
Lender to bring any action, suit, or proceeding in any other forum), and
irrevocably agrees not to assert any objection which it may ever have to the
laying of venue of any such suit, action, or proceeding in any federal or state
court located in Georgia and any claim that any such action, suit, or proceeding
brought in any such court has been brought in an inconvenient forum.

<PAGE>

     9.11  Waiver of Counterclaim.  Borrower and Guarantor each hereby knowingly
           ----------------------
waives the right to assert any counterclaim, other than a compulsory or
mandatory counterclaim, in any action or proceeding brought against either of
them by Lender.

     9.12  Waiver of Jury Trial.  Borrower, Guarantor, and Lender, to the full
           --------------------
extent permitted by law, each hereby knowingly, intentionally, and voluntarily,
with and upon the advice of competent counsel, waives, relinquishes, and forever
forgoes hereby the right to a trial by jury in any action or proceeding,
including, without limitation, any tort action, brought by any of them against
the other based upon, arising out of, or in any way relating to or in connection
with such Loan Document, the Loan, or any course of conduct, act, omission,
course of dealing, statements (whether verbal or written) or actions of any
Person (including, without limitation, such Person's directors, officers,
partners, members, employees, agents or attorneys, or any other Persons
affiliated with such Person), in connection with the Revolving Loan or such Loan
Document, including, without limitation, in any counterclaim which Borrower or
Guarantor may be permitted to assert thereunder or which may be asserted by
Lender against Borrower or Guarantor, whether sounding in contract, tort, or
otherwise.  This waiver by Borrower and Guarantor of their right to a jury trial
is a material inducement for Lender to make the Loan.

     9.13  No Waivers by Lender.  No delay or omission of Lender in exercising
           --------------------
any right or power accruing upon any default under such Loan Document shall
impair any such right or power or shall be construed to be a waiver of any
default under such Loan Document or any acquiescence therein, nor shall any
single or partial exercise of any such right or power or any abandonment or
discontinuance of steps to enforce such right or power, preclude any other or
further exercise thereof or the exercise of any other right or power.
Acceptance of any payment after the occurrence of a default under such Loan
Document shall not be deemed to waive or cure such default under such Loan
Document; and every power and remedy given by such Loan Document to Lender may
be exercised from time to time as often as may be deemed expedient by Lender.
Borrower and Guarantor hereby waive any right to require Lender at any time to
pursue any remedy in Lender's power whatsoever.

     9.14  Waiver of Notice.  Neither Borrower nor Guarantor shall be entitled
           ----------------
to any notices of any nature whatsoever from Lender except with respect to
matters for which such Loan Document specifically and expressly provides for the
giving of notice by Lender to Borrower or Guarantor, as the case may be, and
except with respect to matters for which Borrower or Guarantor, as the case may
be, is not, pursuant to applicable legal requirements, permitted to waive the
giving of notice.  Each of Borrower and Guarantor hereby expressly waives the
right to receive any notice from Lender with respect to any matter for which
such Loan Document does not specifically and expressly provide for the giving of
notice by Lender to Borrower or Guarantor, as the case may be.  Any provision of
such Loan Document which expressly provides for the giving of notice by Lender
to Borrower or Guarantor shall be deemed eliminated ab initio if Lender is
prevented from giving such notice by bankruptcy or other applicable law.

     9.15  Offsets, Counterclaims and Defenses.  Any assignee of such Loan
           -----------------------------------
Document from Lender or any successor or assignee of Lender shall take the same
free and clear of all offsets, counterclaims, or defenses that are unrelated to
such Loan Document which Borrower or Guarantor may otherwise have against any
assignor of such Loan Document, and no such unrelated counterclaim or defense
shall be interposed or asserted by Borrower or Guarantor in any action or
proceeding brought by any such assignee upon such Loan Document, and any such
right to interpose or assert any such unrelated offset, counterclaim or defense
in any such action or proceeding is hereby expressly waived by Borrower and
Guarantor.

     9.16  Time of the Essence.  Time shall be of the essence in the performance
           -------------------
of all obligations of Borrower and Guarantor under such Loan Document.

     9.17  Governing Law.  Such Loan Document shall be governed by, and
           -------------
construed in accordance with, the laws of the State of Georgia.

     9.18  Sole Discretion of Lender.  Wherever pursuant to such Loan Document,
           -------------------------
Lender exercises any right given to it to approve or disapprove, or any
arrangement or term is to be satisfactory to Lender, the decision of Lender to
approve or disapprove or to decide that arrangements or terms are satisfactory
or not satisfactory shall be in the sole discretion of Lender exercised in
subjective good faith and shall be final and conclusive, except as may be
otherwise specifically provided therein.  In addition, Lender shall have the
right to refuse to grant its consent, approval or acceptance or to indicate its
satisfaction whenever such consent, approval, acceptance or satisfaction shall
