                    WELLS REAL ESTATE INVESTMENT TRUST, INC.
                             SHARES OF COMMON STOCK
                              $1,250,000  MINIMUM

     Wells Real Estate Investment Trust, Inc. (the "Company") is a newly
organized Maryland corporation which intends to qualify as a real estate
investment trust ("REIT").  The Company has been formed to acquire and operate
commercial properties, including properties which are under development or
construction, are newly constructed or have been constructed and have operating
histories and some of which may have tenants subject to "triple net" leases
(individually, a "property," collectively, "properties").  The Company's
operations will be managed by Wells Capital, Inc., a Georgia corporation (the
"Advisor"), an Affiliate (as defined herein) of the Company.

     The Company hereby offers, pursuant to this Prospectus (the "Prospectus"),
for sale to the public up to a maximum of 16,500,000 shares and a minimum of
125,000 shares of its common stock, $.01 par value per share (the "Shares").
All of the Shares offered hereby are being offered by the Company.  The minimum
purchase is 100 Shares ($1,000) (except in certain states as described herein).

An investment in Shares involves significant risks (See Risk Factors at page 8),
including the following:

 . The Company's Articles of Incorporation impose restrictions on ownership and
  transfers of Shares, and no public market for the Shares currently exists, and
  there is no assurance that one will develop.

 . The Company may purchase properties from its Affiliates (generally without
  profit to such selling Affiliates), and enter into joint venture agreements
  with its Affiliates and with the Prior Wells Public Programs (as defined
  herein) for the acquisition and development of properties.  Accordingly,
  because such transactions will not be on an arm's-length basis, the Company
  will face inherent conflicts of interest based on such relationships.

 . The Advisor and other Affiliates of the Company are involved in
  partnerships with investment objectives similar to the Company's, and
  therefore will face conflicts of interest in managing the Company's operations
  and those of such other activities. Accordingly, such conflicts may affect
  negatively the Company's financial performance and Cash Available for
  Distribution to Investors (as defined herein).

 . If the Company sells only the minimum amount of Shares required to close the
  Offering, the Company may be able to acquire only an estimated three or fewer
  properties, and thus the Company would have very limited asset diversification
  and possibly no geographic diversification.
  
 . Certain real estate investment programs previously sponsored by the Advisor
  and distributions to investors therein have experienced fluctuating financial
  performance based on varying occupancy levels, amounts of capital improvements
  and other necessary expenses for each property owned by such other programs.

 . The Company does not own any real property, and the Advisor has not identified
  any properties in which there is a reasonable probability that the Company
  will invest.  Accordingly, investors in the Company ("Investors") will not
  have the opportunity to evaluate the properties that the Company will acquire
  and must rely totally upon the ability of the Advisor with respect to the
  acquisition of properties.

 . Failure by the Company to qualify as a REIT for federal income tax purposes
  will cause it to be taxed as a regular corporation under federal income tax
  laws, which would materially reduce the Company's Cash Available for
  Distribution to Investors.

 . The Company may incur indebtedness of up to 50% of the properties' aggregate
  value, though such debt limitation does not apply to individual properties.
  Accordingly, the Company and its properties may be moderately leveraged, which
  could have adverse consequences to the Company.

 . Of the proceeds from the sale of the Shares, approximately 84% will be used to
  acquire properties, and the balance will be paid as commissions and fees to
  certain Affiliates of the Company for their services and as reimbursement for
  certain organizational and offering expenses, though some of such amounts will
  be reallowed or paid directly to participating broker-dealers.

  The Company has registered an offering of 16,500,000 Shares, with 1,500,000 of
such Shares available only to shareholders purchasing Shares in this initial
public offering who receive a copy of this Prospectus and who elect to
Any than By participating in this Offering must be made pursuant to a separate
prospectus.  See "Summary of Reinvestment Plan" and Exhibit C hereto.

  The Company's Affiliates include Wells Capital, Inc.--the Advisor, Wells
Investment Securities, Inc.--the Dealer Manager (the "Dealer Manager"), Wells
Management Company, Inc.--the property manager (the "Management Company"), Wells
Operating Partnership, L.P.--the partnership that will own the properties (the
"Operating Partnership"), and Wells Development Corporation--a property
development company (the "Development Company") .  The Shares are being placed
for the Company by the Dealer Manager on a "best efforts" basis.  See "Plan of
Distribution."

THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION, NOR HAS ANY SUCH
AUTHORITY PASSED UPON THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS.  ANY
REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.  THE ATTORNEY GENERAL OF
THE STATE OF NEW YORK HAS NOT PASSED ON OR ENDORSED THE MERITS OF THIS OFFERING.
ANY REPRESENTATION TO THE CONTRARY IS UNLAWFUL.

                The date of this Prospectus is January 30, 1998.

<PAGE>
 
                   (Cover Page Continued From Previous Page)
Footnotes:
(1)  Price to Public and Selling Commissions may be reduced in connection with
     certain large volume purchases and under other circumstances described
     herein; however, in no event will the proceeds to the Company be reduced
     thereby.  In addition to Selling Commissions in the amount of up to 7% of
     the Gross Offering Proceeds, the Company will reimburse the Dealer Manager
     and nonaffiliated broker-dealers participating in this Offering for actual
     expenses paid for marketing support and due diligence purposes, up to a
     maximum of 2.5% of the Gross Offering Proceeds (the "Marketing and Due
     Diligence Fee").  The Company also will issue to participating dealers a
     warrant to purchase one Share at a price of $12.00 per Share for every 25
     Shares sold (the "Soliciting Dealer Warrants").  See "Plan of
     Distribution."

(2)  These figures are before deducting other expenses of the Offering to be
     paid by the Company in an estimated amount equal to 3% of Gross Offering
     Proceeds -- $4,500,000 if the maximum amount under the Offering is sold and
     $37,500 if the minimum amount is sold -- which amount does not include
     Selling Commissions or amounts reimbursed for due diligence expenses.
     Includes Selling Commissions equal to 7% of the aggregate Gross Offering
     Proceeds (which commissions may be reduced under certain circumstances),
     but excludes the Marketing and Due Diligence Fee of up to 2.5% of Gross
     Offering Proceeds, both of which are payable to the Dealer Manager, an
     Affiliate of the Company.  The Dealer Manager, in its sole discretion, may
     reallow Selling Commissions of up to 7% of Gross Offering Proceeds to other
     broker-dealers participating in this Offering attributable to shares sold
     by them, and may reallow the Marketing and Due Diligence Fee (up to 2.5% of
     Gross Offering Proceeds) as reimbursements to the Dealer Manager and
     broker-dealers participating in this Offering based on such factors as the
     volume of shares sold by such participating broker-dealers, marketing
     support provided by such participating broker-dealers and bona fide
     conference fees incurred.  See "Estimated Use of Proceeds" and "Plan of
     Distribution."

(3)  In addition, assuming all 600,000 Soliciting Dealer Warrants are issued to
     the Dealer Manager, $480 of additional proceeds will be raised, based on a
     purchase price of $.0008 per share.  Assuming all such warrants are
     exercised at the exercise price of $12.00, an additional $1,200,000 will be
     raised.  No Selling Commission will be paid in connection with the issuance
     of the Soliciting Dealer Warrants or the Shares issuable upon the exercise
     thereof.

(4)  The maximum number of Shares to be sold hereunder is 16,500,000, which
     includes 1,500,000 Shares that may be issued pursuant to the Company's
     Dividend Reinvestment Plan (the "Reinvestment Plan"), and 600,000 shares
     that may be issued upon exercise of the Soliciting Dealer Warrants.  Those
     shareholders who elect to participate in the Reinvestment Plan will have
     their dividends reinvested in additional Shares.  The Soliciting Dealer
     Warrants may not be exercised for one year from the date of issuance, and
     are subject to restrictions on transfer.  See "Description of Capital
     Stock-Soliciting Dealer Warrants."

     The Offering will commence upon the effective date of this Prospectus and
will continue until and terminate upon the earlier of (i) January 30, 2000 (two
years after the initial date of this Prospectus), or (ii) the date on which an
aggregate of 15,000,000 Shares (excluding any Shares sold pursuant to the
Reinvestment Plan) (the "Maximum Offering") have been sold.  Subscription
proceeds will be placed in an interest-bearing escrow account with NationsBank,
N.A., Atlanta, Georgia (the "Escrow Agent"), until subscriptions for at least
125,000 Shares (the "Minimum Offering") have been received and accepted by the
Company, at which time the proceeds will be released to the Company to be held
in trust for the benefit of investors.  If the Minimum Offering is not met by
January 30, 1999 (one year after the date of this Prospectus), the Offering will
be terminated and subscriber's funds (plus interest and without deducting for
escrow expenses) will be promptly refunded.

     THE USE OF PROJECTIONS OR FORECASTS IN THIS OFFERING IS PROHIBITED.  ANY
REPRESENTATIONS TO THE CONTRARY AND ANY PREDICTIONS, WRITTEN OR ORAL, AS TO THE
AMOUNT OR CERTAINTY OF ANY PRESENT OR FUTURE CASH BENEFIT OR TAX CONSEQUENCE
WHICH MAY FLOW FROM AN INVESTMENT IN THE COMPANY ARE NOT PERMITTED.

                        incorporated in July 1997 as a Maryland corporation, and
                        intends to qualify as a REIT. The Company's principal
                        place of business and registered office is located at
                        the office of the Advisor: 3885 Holcomb Bridge Road,
                        Norcross, Georgia 30092, and its telephone number at
                        that office is 800-448-1010. The Company intends to
                        operate as an "Up-REIT" through the use of the Operating
                        Partnership for acquisitions of properties.

ADVISOR:                Wells Capital, Inc., incorporated in Georgia in April
                        1984, is the Advisor and will make all investment
                        decisions for the Company, subject to approval by the
                        Board of Directors in certain circumstances. See "The
                        Advisor and the Advisory Agreement." The Advisor is an
                        affiliate of the Company. See "Conflicts of Interest."
                        For information regarding the previous experience of the
                        Advisor and its Affiliates in the management of real
                        estate limited partnerships, see "Prior Performance
                        Summary."

SECURITIES OFFERED:     A Minimum Offering of 125,000 Shares and a Maximum
                        Offering of 16,500,000 Shares (the "Maximum Offering").
                        The Maximum Offering includes up to 1,500,000 Shares to
                        be issued pursuant to the Reinvestment Plan and up to
                        600,000 shares to be issued pursuant to the Soliciting
                        Dealer Warrants. The Shares issued in this Offering and
                        under the Reinvestment Plan are offered at a price of
                        $10 per share.

RISK FACTORS:           An investment in the Shares involves various risks
                        including the following:

                        .  To ensure that the Company will not fail to qualify
                           as a REIT, the Articles of Incorporation, subject to
                           certain exceptions, will limit any person from
                           owning, directly or indirectly, more than 9.8% of the
                           outstanding Shares or more than 9.8% of the number of
                           outstanding shares of any class of the Company's
                           preferred stock.

                        .  Initially, the Shares will not be listed (and
                           therefore not traded) on a securities exchange or any
                           over-the-counter market. However, the Board of
                           Directors may elect to so list the Shares in the
                           future (the "Listing") though there can be no
                           assurances that the Company will ever qualify for
                           such a Listing. Listing does not assure liquidity.
                           There can be no assurance that a market for the
                           Shares will develop. In the event that Listing does
                           not occur by January 30, 2008 (ten years after the
                           initial date of this Prospectus), the Company will be
                           dissolved. See "Description of Capital Stock--
                           Articles of Incorporation and Bylaw Provisions."

                        .  Shareholders must rely on the Advisor and the Board
                           of Directors, who will have full responsibility for
                           the day-to-day management of the Company.

                        .  The number of properties that the Company will
                           acquire and the diversification of its investments
                           will be reduced to the extent that less than the
                           maximum number of Shares are sold. Lack of
                           diversification of 

                                       1
<PAGE>
 
                           the Company's investments will increase the risks
                           associated with an investment in the Shares.

                        .  This Offering involves payment of substantial fees to
                           the Advisor and other Affiliates, some of which will
                           be payable regardless of the success or failure of
                           the Company.

                        . Distributions to investors in certain real estate
                           programs previously sponsored by the Advisor and its
                           Affiliates have fluctuated with real estate business
                           cycles and other external market conditions, as well
                           as varying occupancy levels, amounts of capital
                           improvements and other necessary expenses for each
                           property owned by such other programs. Accordingly,
                           there are no assurances that properties acquired by
                           the Company will be profitable. See "Prior
                           Performance Summary."

                        . The Company will be subject to market and economic
                           risks associated with investments in real estate,
                           which means that both the amount of cash the Company
                           will receive from the lessees of its properties and
                           the future value of its properties cannot be
                           predicted. Accordingly, Cash Available for
                           Distribution and the value of the Company's real
                           estate investments will be dependent upon fluctuating
                           market and economic conditions.

                        . The Company does not own any real property, and the
                           Advisor has not identified any properties in which
                           there is a reasonable probability that the Company
                           will invest. Accordingly, investors will not have the
                           opportunity to evaluate the properties that the
                           Company will acquire and must rely totally upon the
                           ability of the Advisor and the Board of Directors
                           with respect to the acquisition of properties.

                        .  A portion of the proceeds available for Investment in
                           properties may be invested in the acquisition and
                           construction of undeveloped properties, which involve
                           risks relating to the builder's ability to control
                           construction costs, failure to perform, or failure to
                           build in conformity with plan specifications and
                           timetables, thus potentially subjecting the Company
                           to cost overruns and time delays for properties under
                           construction. Increased costs of newly constructed
                           properties may have the effect of reducing Cash
                           Available for Distribution, while construction delays
                           may have the effect of delaying cash flow from the
                           operation of such properties.

                        .  As a result of the fact that the Advisor and its
                           Affiliates serve as general partners of real estate
                           limited partnerships with investment objectives
                           similar to the Company's and will continue to engage
                           in other business activities, the Advisor will have
                           conflicts of interest in allocating its time between
                           the Company and such partnerships and activities. The
                           Advisor also will have conflicts of interest when
                           evaluating potential investments for the Company in
                           deciding which entity will acquire a particular
                           property, and in leasing properties in the event that
                           the Company and another program managed by the
                           Advisor or its Affiliates were to compete for the
                           same tenants in negotiating leases.

                        .  The Company intends to borrow money in connection
                           with the construction and development of properties.
                           Accordingly, the Company will be subject to risks
                           normally associated with debt financing, including

                                       2
<PAGE>
 
                           the risk that the Company will not be able to meet
                           its debt service obligations, and, to the extent that
                           it cannot, the risk that the Company may lose its
                           investment in any properties encumbered by debt.
                           
                        .  The Company intends to elect to be taxed as a REIT
                           for federal income tax purposes. In order to qualify
                           to be taxed as a REIT, the Company must meet numerous
                           organizational and operating requirements. While the
                           Company has received an opinion of counsel that it
                           will qualify to be taxed as a REIT, this opinion is
                           not binding on the Service or any court. In the event
                           that the Company fails to qualify as a REIT, it will
                           be taxed as a corporation, which could have a
                           material adverse effect on the Company's Cash
                           Available for Distribution.

                           See "Risk Factors" for a discussion of the risk
                           factors relating to an investment in the Shares.

TERMS OF THE OFFERING:     The Offering will commence upon the date of this
                           Prospectus and will continue until and terminate upon
                           the earlier of (i) two years after the date of this
                           Prospectus, or (ii) the date on which an aggregate of
                           15,000,000 Shares (excluding Shares sold pursuant to
                           the Dividend Reinvestment Plan) have been sold,
                           provided, that if the Minimum Offering is not sold
                           within one year of the date of this Prospectus, the
                           Offering will be terminated and investors' funds,
                           with interest and not net of escrow expenses, will be
                           returned promptly. Subscription proceeds will be held
                           in escrow until investors are admitted as
                           shareholders, which will occur no less often than
                           quarterly.

PROPERTIES:                The Company will seek to acquire and operate
                           commercial properties, including without limitation,
                           office buildings, shopping centers, business and
                           industrial parks and other commercial and industrial
                           properties, including properties which are under
                           construction or development, are newly constructed,
                           or have been constructed and have operating
                           histories. All such properties may be acquired,
                           developed and operated by the Company alone or
                           jointly with another party. The Company is likely to
                           enter into one or more joint ventures with certain of
                           its Affiliates and the present and future real estate
                           limited partnership sponsored by the Advisor for the
                           acquisition of properties. As of the date of this
                           Prospectus, the Company has neither purchased nor
                           contracted to purchase any properties, nor has the
                           Advisor identified any properties in which there is a
                           reasonable probability that the Company will invest.
                           The Company may incur indebtedness of up to 50% of
                           its properties' aggregate value. Such limitation,
                           however, does not apply to individual properties. The
                           Company intends to use the straight-line depreciation
                           method for its properties. See "Real Property
                           Investments," "Investment Objectives and Criteria,"
                           "Conflicts of Interest," and "Glossary."

ESTIMATED USE OF
 PROCEEDS OF OFFERING:     It is anticipated that approximately 84% of the
                           proceeds of this Offering will actually be invested
                           in properties, and the remainder will be used to pay
                           selling commissions and fees and expenses relating to
                           the selection and acquisition of properties and the
                           costs of organizing the Company and the Offering. See
                           "Estimated Use of Proceeds" for a more detailed
                           discussion of the Company's estimated use of the
                           proceeds of the Offering, which includes proceeds
                           from shares

                           sold pursuant to the Reinvestment Plan, but excludes
                           proceeds from shares sold pursuant to the Soliciting
                           Dealer Warrants. See also "Management Compensation"
                           regarding the compensation and fees to be paid to the
                           Advisor and other Affiliates.

INVESTMENT OBJECTIVES:     The Company's objectives are: (i) to preserve,
                           protect and return the Invested Capital (as defined
                           herein) of the shareholders; (ii) to maximize Cash
                           Available for Distribution; (iii) to realize capital
                           appreciation upon the ultimate sale of Company's
                           properties; and (iv) to provide shareholders with
                           liquidity of their investment within ten years after
                           the commencement of the Offering through either (a)
                           the Listing of the Shares, or (b) if Listing does not
                           occur within ten years following the commencement of
                           the Offering, the dissolution of the Company and
                           orderly liquidation of its assets. Distributions to
                           investors in certain real estate investment programs
                           previously sponsored by the Advisor, as shown in the
                           Prior Performance Tables included as Exhibit A
                           hereto, have fluctuated with real estate business
                           cycles and other external market conditions, as well
                           as varying occupancy levels, amounts of capital
                           improvements and other necessary expenses for each
                           property owned by such other programs. Many of the
                           real properties in which such prior programs have
                           invested have experienced the same economic problems
                           as other real estate investments in recent years,
                           including without limitation, general over-building
                           and an excess of supply in many markets, along with
                           increased operating costs and a general downturn in
                           the real estate industry. These prior Funds have not
                           yet sold any real property investments and thus no
                           evaluation can be made as to whether these prior
                           programs will achieve their objectives of returning
                           capital contributions or realizing capital
                           appreciation upon the sale of such properties. See
                           "Investment Objectives and Criteria" and "Prior
                           Performance Summary."

CONFLICTS OF INTEREST:     The Advisor and other Affiliates will experience
                           conflicts of interest in connection
                           with the management of the Company,
                           including the following:

                           .    The Advisor and certain of its Affiliates serve
                                as general partners of real estate limited
                                partnerships that have objectives similar to the
                                Company's and expect that they will organize
                                additional real estate partnerships in the
                                future. As a result, investors should be aware
                                that the Advisor will have to allocate its time
                                between the Company and such partnerships and
                                activities and may have conflicts of interest in
                                deciding which entity will acquire a particular
                                property.
                                
                           .    The Company may acquire properties in the same
                                geographic areas where other properties owned or
                                managed by the Advisor or other Affiliates are
                                located, resulting in potential conflicts in the
                                leasing or resale of the Company's properties in
                                the event that the Company and another program
                                managed by the Advisor were to attempt to
                                compete for the same tenants in negotiating
                                leases or to sell similar properties at the same
                                time.

                           .    Since it is anticipated that the Company's
                                properties will be managed by the Management
                                Company, an Affiliate of the Advisor, the
                                Company will not have the benefit of independent
                                property management, and investors must rely on
                                the Advisor and the Management Company, for
                                management of the Company's properties.

                            .   The Company is likely to enter into one or more
                                joint ventures for the acquisition and operation
                                of specific properties with one or more real
                                estate limited partnerships sponsored by the
                                Advisor and other Affiliates,

                                resulting in potential conflicts of interest in
                                determining which program should enter into a
                                particular joint venture, in structuring the
                                terms of the relationship and in managing the
                                joint venture. In addition, the Company may
                                purchase properties from the Advisor and other
                                Affiliates (with no profit to the Advisor or
                                such selling Affiliate), resulting in conflicts
                                of the Advisor based on its relationship with
                                both parties to such transactions. See
                                "Conflicts of Interest."

                            .   Fees payable to the Advisor and other Affiliates
                                in connection with Company transactions
                                involving the purchase, management and sale of
                                Company properties are not the result of arm's-
                                length negotiations and will be payable
                                regardless of the quality of the property
                                acquired or the services provided to the
                                Company.

                            .   The conflicts of interest created at the time of
                                a sale of a property by: (a) the loss of
                                management fees by the Management Company
                                conflicting with the brokerage fee which may be
                                received by the Advisor, and (b) the receipt of
                                brokerage fees by the Advisor conflicting with
                                the advisability of such a sale.

                            .   The Company's Affiliates include Wells Capital,
                                Inc.--the Advisor, Wells Investment Securities,
                                Inc.--the Dealer Manager, Wells Management

                                Partnership, and Wells Development Corporation--
                                the Development Company.

                            various conflicts of interest relating to an
                            investment in the Shares.

PRIOR OFFERING SUMMARY:     The Advisor and its Affiliates have previously
                            sponsored eleven publicly offered real estate
                            limited partnerships on an unspecified property or
                            "blind pool" basis (the "Prior Wells Public
                            Programs"). The total amount of funds raised from
                            the approximately 24,000 investors in the Prior
                            Wells Public Programs as of August 31, 1997 was
                            approximately $257,000,000, and the amount of such
                            funds invested in properties as of August 31, 1997,
                            was approximately $200,000,000. Distributions to
                            investors in certain real estate investment programs
                            previously sponsored by the Advisor have fluctuated
                            with real estate business cycles and other external
                            market conditions, as well as varying occupancy
                            levels, amounts of capital improvements and other
                            necessary expenses for each property owned by such
                            other programs. The "Prior Performance Summary"
                            section of this Prospectus contains a discussion of
                            the Prior Wells Public Programs. Certain statistical
                            data relating to the Prior Wells Public Programs are
                            contained in the Prior Performance Tables included
                            as Exhibit A to this Prospectus.

                            paid regardless of the quality of the property
                            acquired or the services provided to the Company.

                            of which will be paid to third parties unaffiliated

                            (subject to certain overall limitations) (the
                            "Acquisition and Advisory Fees"), which is payable

                            income from each property, approximately 2% to 3% of
                            which is expected to be generated from direct tenant
                            chargebacks, resulting in a net amount payable by
                            each property of approximately 1.5% to 2.5%; and in
                            the case of leases to new tenants, an initial

                            adjusted amount of capital invested in the Company.
                                
                            Liquidation Stage: After all shareholders have
                            received a return of their Invested Capital and an
                            8% per annum cumulative, noncompounded return on

                            of the property sale (the "Common Return"), then the
                            Advisor is entitled to receive (a) a return of
                            contributed capital in Liquidating Distributions,
                            and (b) 10% of remaining amounts of Nonliquidating
                            Net Sale Proceeds and Liquidating Distributions

                            is subject to conditions and restrictions or to
                            change under certain specified circumstances. The
                            Advisor and other Affiliates also may receive
                            reimbursement for out-of-pocket expenses that they
                            incur on behalf of the Company, subject to certain
                            expense limitations, and a subordinated incentive
                            fee if Listing occurs.

SHARE REDEMPTION:           The Company may use proceeds received from sales of
                            Shares pursuant to the Reinvestment Plan to redeem
                            Shares at its sole discretion. Shareholders will
                            have no right to request that the Company redeem
                            their Shares after Listing.

DIVIDEND REINVESTMENT PLAN: The Company will establish the Reinvestment Plan
                            pursuant to which shareholders who elect to
                            participate may have their dividends from the
                            Company automatically invested in Shares.
                            Shareholders who participate in the Reinvestment
                            Plan will be

                            allocated their share of the Company's taxable
                            income even though such shareholders will receive no
                            cash distributions from the Company, which may
                            result in tax liability for such participants even
                            though they would receive no cash distributions with
                            which to pay such tax liability. The Company may
                            terminate the Reinvestment Plan for any reason at
                            any time with ten days' prior notice to
                            participants. See "Dividend Reinvestment Plan" and
                            "Risk Factors--Fed eral Income Tax Risks."

DISTRIBUTION POLICY:        As a REIT, the Company will be required to
                            distribute to its shareholders at least 95% of its
                            annual net taxable income. Because the Company has
                            not identified any probable acquisitions, there can
                            be no assurances as to when the Company will begin
                            to generate net taxable income and to make 
                            distributions.

TAX STATUS:                 The Company intends to qualify and will elect to be
                            taxed as a REIT under sections 856 through 860 of
                            the Code, commencing with the taxable year ending
                            December 31 of the year in which the Offering is
                            closed. If the Company qualifies for taxation as a
                            REIT, the Company generally will not be subject to
                            federal corporate income tax on its taxable income
                            that is distributed to its shareholders. A REIT is
                            subject to a number of organizational and
                            operational requirements, including a requirement
                            that it currently distribute at least 95% of its
                            annual taxable income. Although the Company does not
                            intend to request a ruling from the Internal Revenue
                            Service (the "Service) as to its REIT status, the
                            Company has received an opinion of Hunton &
                            Williams, its legal counsel, that the Company will
                            qualify as a REIT for its taxable year ending
                            December 31 of the year in which the Offering is
                            closed, and the Company's organization and proposed
                            method of operation will enable it to continue to
                            qualify as a REIT, which opinion is based on certain
                            assumptions and representations about the Company's
                            ongoing businesses and investment activities and
                            other matters. No complete assurance can be given
                            that the Company will be able to comply with such
                            assumptions and representations in the future.
                            Furthermore, such opinion is not binding on the
                            Service or on any court. Even if the Company
                            qualifies for taxation as a REIT, the Company may be
                            subject to certain federal state and local taxes on
                            its income and property. Failure to qualify as a
                            REIT would render the Company subject to federal
                            income tax (including any applicable alternative
                            minimum tax) on its taxable income at regular
                            corporate rates and distributions to the Company's
                            shareholders in any such year would not be
                            deductible. See "Risk Factors--Legal Risks--Tax
                            Risks" and "Federal Income Tax Considerations --
                            Taxation of the Company."

OPERATING PARTNERSHIP:      The Company intends to own its properties through
                            the Operating Partnership. Initially, the Company
                            will be the sole general partner of the Operating
                            Partnership, and the Advisor will contribute
                            $200,000 to the Operating Partnership and will be
                            the sole limited partner thereof. This "UPREIT"
                            structure will allow the Company to acquire
                            properties by exchanging units of limited
                            partnership interest in the Operating Partnership
                            ("OP Units") for interests in properties, which
                            generally will allow sellers of properties to defer
                            gain recognition with respect to such properties.
                            Holders may redeem OP Units for cash equal to the
                            value of one Share or, at the option of the Company,
                            holders may receive one Share for each tendered OP
                            Unit.

LISTING:                    Initially, the Company's Shares will not be listed,
                            but the Board of Directors may elect to effect the
                            Listing of the Shares at any time following the
                            completion of the Offering, though there can be no
                            assurances that the Board of Directors will make
                            such election or that the Company will ever qualify
                            for Listing. In the event that the Listing does not
                            occur on or before January 30, 2008 (ten years after
                            the date of the Prospectus), the Company will
                            automatically terminate and dissolve, unless the
                            shareholders holding a majority of the Common Shares
                            vote to extend the duration of the Company.

                                  RISK FACTORS

     The purchase of Shares involves a number of risks.  In addition to the
factors set forth elsewhere in this Prospectus, prospective investors should
consider specifically the following:

INVESTMENT RISKS

     LACK OF LIQUIDITY OF SHARES.  Shareholders may not be able to sell their
Shares promptly at a desired price; therefore, the Shares should be considered
as a long-term investment only.  Currently there is no public market for the
Shares.  The Board of Directors, with or without the consent of the
shareholders, may apply for Listing of the Shares if the Board of Directors
(including a majority of Independent Directors) determines Listing to be in the
best interests of the shareholders.  There can be no assurance, however, that
the Company will apply for Listing, that any such application will be made
before the passage of a significant period of time, that any application will be
accepted or, even if accepted, that a public trading market will develop,  In
any event, the Articles of Incorporation provide that the Company will not apply
for Listing before the completion or termination of the Offering.  See
"Description of Capital Stock."

     TOTAL RELIANCE ON THE ADVISOR.  All decisions with respect to the
management of the Company will be made by the Advisor, with oversight from the
Board of Directors.  The shareholders will have no right or power to take part
in the management of the Company except through the exercise of their voting
rights, which are limited.  The Advisor may be removed under certain conditions,
as set forth in the Advisory Agreement, subject to payment and release from all
obligations incurred by the Advisor in connection with its role as advisor.
Further, the Advisor has the ability to assign the Advisory Agreement to an
affiliate, subject to approval by the Company's Independent Directors.  In such
case, the shareholders will not be able to vote on such new Advisor, and there
can be no assurances that such new Advisor will perform satisfactorily.  See
"Management," "Management Compensation" and "The Advisor and the Advisory
Agreement."


     CONFLICTS OF INTEREST RELATED TO THE COMPANY'S AFFILIATES. In connection
with its relationship with the Advisor and other Affiliates, the Company has
several conflicts of interest, including the following: (a) The Advisor and
certain of its Affiliates serve as general partners of real estate limited
partnerships that have objectives similar to the Company's and expect that they
will organize additional real estate partnerships in the future. As a result,
investors should be aware that the Advisor will have to allocate its time
between the Company and such partnerships and activities and may have conflicts
of interest in deciding which entity will acquire a particular property; (b) The
Company may acquire properties in the same geographic areas where other
properties owned or managed by the Advisor or other Affiliates are located,
resulting in potential conflicts in the leasing or resale of the Company's
properties in the event that the Company and another program managed by the
Advisor were to attempt to compete for the same tenants in negotiating leases or
to sell similar properties at the same time; (c) Since it is anticipated that
the Company's properties will be managed by the Management Company, an Affiliate
of the Advisor, the Company will not have the benefit of independent property
management, and investors must rely on the Advisor and the Management Company,
for management of the Company's properties; (d) The Company is likely to enter
into one or more joint ventures for the acquisition and operation of specific
properties with one or more real estate limited partnerships sponsored by the
Advisor and other Affiliates, resulting in potential conflicts of interest in
determining which program should enter into a particular joint venture, in
structuring the terms of the relationship and in managing the joint venture. In
addition, the Company may purchase properties from the Advisor and other
Affiliates (without profit to such selling Affiliates) resulting in conflicts of
the Advisor based on its relationship with both parties to such transactions;
(e) Fees payable to the Advisor and other Affiliates in connection with Company
transactions involving the purchase, management and sale of Company properties
are not the result of arm's-length negotiations and will be payable regardless
of the quality of the property acquired or the services provided to the Company;
(f) The conflicts of interest created at the time of a sale of a property by:
(i) the loss of management fees by the Management Company conflicting with the
brokerage fee which may be received by the Advisor, and (ii) the receipt of
brokerage fees by the Advisor conflicting with the advisability of such a sale.
The Company's Affiliates include Wells Capital, Inc.--the Advisor, Wells
Investment Securities, Inc.--the Dealer Manager, Wells Management Company, Inc.
- --the Management Company, Wells Operating Partnership, L.P.--the Operating
Partnership, and Wells Development Corporation--the Development Company.
Collectively, these several

                                       9
<PAGE>
 
relationships among the Company and the Affiliates reduce substantially the
presence of independent, arm's length managerial and advisory influence on the
operations of the Company. Consequently, such affiliated relationships and
conflicts of interest have the potential to reduce the Company's financial
performance and return to investors. See "Conflicts of Interest" and "The
Advisor and Advisory Agreement."

     POSSIBLE LACK OF DIVERSIFICATION RESULTING FROM SUBSCRIPTIONS FOR LESS THAN
THE MAXIMUM NUMBER OF SHARES.  To the extent that less than the Maximum Offering
is sold, the diversification of the Company's investments will be decreased and
the extent to which the Company's profitability will be affected by any one of
its investments will increase.  Specifically, the various types of real estate
assets in which the Company invests and the geographic diversity of such assets
will be reduced proportionally.  Consequently, the effects of the financial
performance of such fewer assets will be concentrated and thus the risks of poor
financial performance will be increased.  Further, reduced geographic diversity
of the Company's properties will increase the Company's reliance on (and
therefore risks) related to regional economic conditions.  Accordingly, lack of
diversification of the Company's investments will have the effect of increasing
the risks associated with an investment in the Shares.  See "Estimated Use of
Proceeds" and "Investment Objectives and Criteria."

     SUBSTANTIAL MANAGEMENT COMPENSATION; PROCEEDS TO BENEFIT AFFILIATED
PARTIES.  The Advisor and the other Affiliates will perform services for the
Company in connection with the offer and sale of Shares, the selection and
acquisition of the Company's properties, and the management and leasing of the
Company's properties, and will receive substantial compensation from the Company
in consideration for these services.  In connection with the Offering, the
Dealer Manager will receive 7% ($10,500,000 at the Maximum Offering) of the
Gross Offering Proceeds as a Selling Commission and a Marketing and Due
Diligence Fee equal to 2.5% ($3,750,000 at the Maximum Offering) for marketing
and due diligence reimbursements, substantially all of which is expected to be
reallowed to participating broker-dealers.  In connection with the review and
evaluation of potential acquisitions, the Advisor will receive Acquisition and
Advisory Fees equal to 3% ($4,500,000 at the Maximum Offering) of the Gross
Offering Proceeds.  In connection with the management and leasing of properties,
the Management Company will receive a fee equal to 4.5% of the gross rental
income from each property as well as certain leasing fees, though approximately
2% to 3% of such 4.5% fee is expected to be generated from direct chargebacks to
tenants of such properties, resulting in a net fee payable by the properties of
1.5% to 2.5%.  The amount of such compensation has not been determined in arm's-
length negotiations, and such amounts will be payable regardless of the quality
of services provided to the Company.  Further, the Selling Commission, Marketing
and Due Diligence Fee, Organization and Offering Expense Fee and the initial
Acquisition and Advisory Fees will be paid to Affiliates prior to any
distributions to shareholders.  See "Management Compensation" and "Conflicts of
Interest."

     NO IDENTIFIED SOURCES FOR FUNDING OF FUTURE CAPITAL NEEDS.  As the Company
raises capital from investors, substantially all of the Gross Proceeds of the
Offering will be used for investment in properties and for payment of various
fees and expenses.  See "Estimated Use Of Proceeds."  In order to qualify as a
REIT, the Company must distribute to its shareholders at least 95% of its annual
taxable income.  Therefore, it is not anticipated that the Company will maintain
any meaningful permanent working capital reserves.  Accordingly, in the event
that the Company develops a need for additional capital in the future for the
improvement of its properties or for any other reason, no sources for such
funding have been identified, and no assurance can be made that such sources of
funding will be available to the Company for potential capital needs in the
future or, if available, that such funds can be obtained on economically
feasible terms.  See "Estimated Use of Proceeds" and "Investment Objectives and
Criteria."

     JOINT VENTURES MAY NEGATIVELY AFFECT THE COMPANY.  The Company is likely to
enter into one or more joint ventures with Affiliates for the acquisition,
development or improvement of properties.  In this regard, the Company may enter
into joint ventures with future programs sponsored by the Advisors or other
Affiliates or with one or more Prior Wells Public Programs.  The Company may
purchase and develop properties in joint ventures or in partnerships, co-
tenancies or other co-ownership arrangements with the Advisor or other
Affiliates, the sellers of the properties, affiliates of the sellers, developers
or other persons.  Such investments may, under certain circumstances, involve
risks not otherwise present, including, for example, the possibility that the
Company's co-venturer, co-tenant or partner in an investment might become
bankrupt, that such co-venturer, co-tenant or partner may at any time have
economic or business interests or goals which are inconsistent with the business
interests or goals of the Company, or that such co-venturer, co-tenant or
partner may be in a position to take action contrary to the instructions or the
requests of the Company or contrary to the Company's policies or objectives.
Actions by such a co-venturer, co-tenant or partner might

                                       10
<PAGE>
 
have the result of subjecting the applicable property to liabilities in excess
of those otherwise contemplated and may have the effect of reducing Cash
Available for Distribution. In the event a co-venturer has a right of first
refusal to buy out the other co-venturer, it may be unable to finance such buy-
out at that time. It may also be difficult for the Company to sell its interest
in any such joint venture or partnership or as a co-tenant in such property. In
addition, to the extent that the Company's co-venturer or partner is the Advisor
or one of its Affiliates, certain conflicts of interest will exist. See
"Conflicts of Interest--Joint Ventures with the Advisor and other Affiliates."

     ANTI-TAKEOVER EFFECTS OF GOVERNING DOCUMENTS AND MARYLAND LAW.  Certain
provisions of the Company's Articles of Incorporation, including the ownership
limitations, transfer restrictions and ability to issue preferential preferred
stock, may have the effect of preventing, delaying or discouraging takeovers of
the Company by third parties.  In addition, certain provisions of the Maryland
General Corporation Law ("MGCL"), including the restrictions on certain business
combinations and control share acquisitions, may have a similar effect.  See
"Description of Capital Stock."

     REINVESTMENT PLAN PROCEEDS MAY NOT BE USED TO ACQUIRE PROPERTIES.  Proceeds
from sale of Shares in the Reinvestment Plan may, in the Advisor's discretion,
be used to fund the Share Repurchase Program rather than for the funding of real
estate investment.  In such case, the Company's real estate investments, and
therefore the underlying value of the Shares and potential distributions to
shareholders, will not be increased by the amount of net proceeds so directed
into the Share Repurchase Program.  See "Summary of Reinvestment Plan."

REAL ESTATE RISKS


     FLUCTUATING FINANCIAL PERFORMANCE OF PREVIOUSLY SPONSORED PROGRAMS.
Distributions to investors in certain real estate investment programs previously
sponsored by the Advisor have fluctuated with real estate business cycles and
other external market conditions, as well as varying occupancy levels, amounts
of capital improvements and other necessary expenses for each property owned by
such other programs. The real properties in which the Prior Wells Public
Programs have invested have experienced the same economic problems as other real
estate investments in recent years, including, without limitation, general over-
building and an excess of supply in many markets, along with increased operating
costs and a general downturn in the real estate industry. The historical
fluctuations in net income of the Prior Wells Public Programs were primarily due
to tenant turnover, resulting in increased vacancies and the requirement to
expend funds for tenant refurbishments, and increases in administrative and
other operating expenses. Specifically, certain of the Prior Wells Public
Programs suffered decreases in net income during the real estate recession of
the late 1980s and early 1990s, which decreases were generally attributable to
the overall downturn in the economy and in the real estate market in particular.
Because of the cyclical nature of the real estate market, such downturns in the
performance of a real estate program could occur at any time in the future when
economic conditions decline. None of the Prior Wells Public Programs has
liquidated or sold any of its real properties to date and, accordingly, no
assurance can be made that such programs will ultimately be successful in
meeting their investment objectives. There are no assurances that properties
acquired by the Company will not also experience fluctuating financial
performance. See "Prior Performance Summary" and the Prior Performance Tables
included as Exhibit A hereto.


     POTENTIAL ADVERSE ECONOMIC AND REGULATORY CHANGES.  The Company will be
subject to risks generally incident to the ownership of real estate, including
changes in general economic or local conditions, changes in supply of or demand
for similar or competing properties in an area, changes in interest rates and
availability of permanent mortgage funds which may render the sale of a property
difficult or unattractive, and changes in tax, real estate, environmental and
zoning laws.  Periods of high interest rates and tight money supply may make the
sale of properties more difficult.  For these and other reasons, no assurance of
profitable operation or realization of gains from the sales of the Company's
properties can be given.  See "Investment Objectives and Criteria."

     "BLIND POOL" OFFERING; LACK OF PROPERTIES REQUIRES TOTAL RELIANCE ON
ABILITIES OF ADVISOR.  This Offering is commonly referred to as a "blind pool"
offering in that the Advisor has not identified any properties in which there is
a reasonable probability that the Company will invest.  Investors must rely upon
the ability of the Advisor and the Board of Directors with respect to the
investment of the proceeds of this Offering and the management of the
unspecified properties and will not have an opportunity to evaluate for
themselves the relevant economic, financial and other information regarding the
specific properties in which the proceeds of this Offering will be invested.
Accordingly, the

                                       11
<PAGE>
 
risk of investing in the Shares may be increased. No assurance can be given that
the Company will be successful in obtaining suitable investments or that, if
investments are made, the objectives of the Company will be achieved. See
"Estimated Use of Proceeds," "The Advisor and Advisory Agreement" and
"Investment Objectives and Criteria."

     INDEBTEDNESS ON PROPERTIES BRINGS RISKS.  The Company intends to borrow
money in connection with the construction and development of properties.
Accordingly, the Company will be subject to risks normally associated with debt
financing, including the risk that the Company will not be able to meet its debt
service obligations, and, to the extent that it cannot, the risk that the
Company may lose its investment in any properties encumbered by debt.  The
Company may incur indebtedness of up to 50% of the properties' aggregate value,
though such debt limitation does not apply to individual properties.  However,
the Company expects that its aggregate indebtedness generally will not exceed
such 50% limit.  Accordingly, the Company and its properties may be moderately
leveraged, which could have adverse consequences to the Company, including the
potential for loss of one or more properties if any such secured debt is
defaulted upon and imposition of operating restrictions on the Company by such
lenders.  See "Investment Objectives and Criteria--Borrowing Policies."

     POTENTIAL INCREASED COSTS AND DELAYS RELATED TO PROPERTY DEVELOPMENT.  The
Company may invest some or all of the net proceeds of this Offering in the
acquisition and development of properties upon which it will develop and
construct improvements at a fixed contract price, provided that the Company may
not invest more than 10% of is total assets in properties which are not expected
to produce income within two years of their acquisition.  In this regard, the
Company will be subject to risks relating to the builder's ability to control
construction costs or to build in conformity with plans, specifications and
timetables.  The builder's failure to perform may necessitate legal action by
the Company to rescind its purchase or the construction contract or to compel
performance.  Performance also may be affected or delayed by conditions beyond
the builder's control.  Delays in completion of construction could also give
lessees the right to terminate preconstruction leases for space at a newly
developed project.  Additional risks may be incurred where the Company makes
periodic progress payments or other advances to such builders prior to
completion of construction.  However, the Company will make such payments only
after having received a certification from an independent architect or an
independent engineer, or both, as to the percentage of the project which has
been completed and as to the dollar amount of the construction then completed.
Factors such as those discussed above can result in increased costs of a project
and a corresponding depletion of the Company's working capital reserves or loss
of the Company's investment.  In addition, the Company will be subject to normal
lease-up risks relating to newly constructed projects.  Furthermore, the price
to be paid for a property upon which improvements are to be constructed or
completed, which price is normally agreed upon at the time of acquisition, of
necessity must be based upon projections of rental income and expenses or fair
market value of the property upon completion of construction, which are not
certain until after a number of months of actual operation.  See "Investment
Objectives and Criteria--Development and Construction of Properties."

     COMPETITION FOR INVESTMENTS.  The Company will experience competition for
real property investments from individuals, corporations and bank and insurance
company investment accounts, as well as other real estate investment
partnerships, including the Prior Wells Public Programs, real estate investment
trusts and other entities engaged in real estate investment activities.  For
example, one Prior Wells Public Program has approximately $11,000,000 available
for real estate investments, and another will be seeking up to $35,000,000 in
investments, both of which will compete with the Company for real estate
investment opportunities and both of which are managed by the Advisor.
Competition for investments may have the effect of increasing costs and reducing
Cash Available for Distribution.  See "Conflicts of Interest."

     POTENTIAL ADVERSE EFFECTS OF DELAYS IN INVESTMENTS.  Delays which may take
place in the selection, acquisition and development of properties could
adversely affect the per Share Cash Available for Distribution as a result of
the lower returns that will be received by the Company if it is required to
invest in short-term investments.  Also, where properties are acquired prior to
the commencement of construction or during the early stages of construction, it
will typically take several months to complete construction and rent available
space.  See "Investment Objectives and Criteria."

     FAILURE TO LIST AND RESULTING LIQUIDATION MAY ADVERSELY AFFECT RETURNS TO
STOCKHOLDERS.  The Company intends, to the extent consistent with its objective
of qualifying as a REIT, to reinvest Net Sales Proceeds from the sale of its
properties in additional properties for at least the first five to ten years
after commencement of the Offering.

                                       12
<PAGE>
 
Unless Listing occurs within ten years after commencement of the Offering, the
Company will undertake, to the extent consistent with the Company's objective of
qualifying as a REIT, the orderly sale of the Company's assets, the distribution
of the Net Sales Proceeds of such sales to stockholders, and will engage only in
activities related to its orderly liquidation unless the stockholders elect
otherwise. If Listing occurs, the Company will become a perpetual life entity,
and Net Sales Proceeds may be reinvested in other properties for an indefinite
period of time. Neither the Advisor nor the Board of Directors may be able to
control the timing of sales due to market conditions, and there can be no
assurance that the Company will be able to sell its assets so as to return
stockholders' aggregate Invested Capital, or to generate a profit for the
stockholders. Invested Capital, in the aggregate, will be returned to
shareholders upon disposition of the Company's properties only if the properties
are sold for more than their original purchase price, although return of
capital, for federal income tax purposes, is not necessarily limited to
stockholder distributions following sales of properties. See "Federal Income Tax
Considerations." In the event that a purchase money obligation is taken in
partial payment of the sales price of a property, the proceeds of the sale will
be realized over a period of years.

     POTENTIAL LIABILITIES RELATED TO ENVIRONMENTAL MATTERS.  Under various
federal, state and local environmental laws, ordinances and regulations, a
current or previous owner or operator of real property may be liable for the
cost of removal or remediation of hazardous or toxic substances on, under or in
such property.  Such laws often impose liability whether or not the owner or
operator knew of, or was responsible for, the presence of such hazardous or
toxic substances.  Environmental laws also may impose restrictions on the manner
in which property may be used or businesses may be operated.  Environmental laws
provide for sanctions in the event of noncompliance and may be enforced by
governmental agencies or, in certain circumstances, by private parties.  In
connection with the acquisition and ownership of its properties, the Company may
be potentially liable for such costs.  The cost of defending against claims of
liability, of compliance with environmental regulatory requirements or of
remediating any contaminated property could materially adversely affect the
business, assets or results of operations of the Company and, consequently, Cash
Available for Distribution.  See "Real Property Investments."

     UNINSURED LOSSES.  Material damages at one or more of its Properties that
are not covered, or not adequately covered, by insurance could have a material
adverse effect on the Company.  Although the Company believes it is adequately
insured, there can be no assurances that material uninsured losses will not
occur in the future.

TAX RISKS

     FAILURE TO QUALIFY AS A REIT.  The Company intends to operate so as to
qualify as a REIT for federal income tax purposes.  Although the Company has not
requested, and does not expect to request, a ruling from the Service that it
qualifies as a REIT, it has received an opinion of its counsel that, based on
certain assumptions and representations, it so qualifies.  Investors should be
aware, however, that opinions of counsel are not binding on the Service or any
court.  The REIT qualification opinion only represents the view of counsel to
the Company based on counsel's review and analysis of existing law, which
includes no controlling precedent.  Furthermore, both the validity of the
opinion and the qualification of the Company as a REIT will depend on the
Company's continuing ability to meet various requirements concerning, among
other things, the ownership of its outstanding stock, the nature of its assets,
the sources of its income, and the amount of its distributions to its
shareholders.  See "Federal Income Tax Considerations--Taxation of the Company."

     If the Company were to fail to qualify as a REIT for any taxable year, the
Company would not be allowed a deduction for distributions to its shareholders
in computing its taxable income and would be subject to federal income tax
(including any applicable alternative minimum tax) on its taxable income at
regular corporate rates.  Unless entitled to relief under certain Code
provisions, the Company also would be disqualified from treatment as a REIT for
the four taxable years following the year during which qualification was lost.
As a result, Cash Available for Distribution would be reduced for each of the
years involved.  Although the Company intends to operate in a manner intended to
allow it to qualify as a REIT, it is possible that future economic, market,
legal, tax or other considerations may cause the Board of Directors to revoke
the Company's REIT election.  See "Federal Income Tax Considerations."

     REIT MINIMUM DISTRIBUTION REQUIREMENTS; POSSIBLE INCURRENCE OF ADDITIONAL
DEBT.  In order to qualify as a REIT, the Company generally will be required
each year to distribute to its shareholders at least 95% of its net taxable

                                       13
<PAGE>
 
income (excluding any net capital gain).  In addition, the Company will be
subject to a 4% nondeductible excise tax on the amount, if any, by which certain
distributions paid by it with respect to any calendar year are less than the sum
of (i) 85% of its ordinary income for that year, (ii) 95% of its capital gain
net income for that year, and (iii) 100% of its undistributed taxable income
from prior years.

     The Company intends to make distributions to its shareholders to comply
with the 95% distribution requirement and to avoid the nondeductible excise tax.
The Company's income will consist primarily of its share of the income of the
Operating Partnership, and the Cash Available for Distribution by the Company to
its shareholders will consist of its share of cash distributions from the
Operating Partnership.  Differences in timing between (i) the actual receipt of
income and actual payment of deductible expenses and (ii) the inclusion of such
income and deduction of such expenses in arriving at taxable income of the
Company could require the Company, through the Operating Partnership, to borrow
funds on a short-term basis to meet the 95% distribution requirement and to
avoid the nondeductible excise tax.  The requirement to distribute a substantial
portion of the Company's net taxable income could cause the Company to
distribute amounts that otherwise would be spent on future acquisitions,
unanticipated capital expenditures or repayment of debt, which would require the
Company to borrow funds or to sell assets to fund the costs of such items. See
"Federal Income Tax Considerations --Taxation of the Company."

     FAILURE OF THE OPERATING PARTNERSHIP TO BE CLASSIFIED AS A PARTNERSHIP FOR
FEDERAL INCOME TAX PURPOSES; IMPACT ON REIT STATUS.  Although the Company has
not requested, and does not expect to request, a ruling from the Service that
the Operating Partnership will be classified as a partnership for federal income
tax purposes, the Company has received an opinion of its counsel stating that
the Operating Partnership will be classified as a partnership, and not as a
corporation or association taxable as a corporation for federal income tax
purposes.  If the Service were to challenge successfully the tax status of the
Operating Partnership as a partnership for federal income tax purposes, the
Operating Partnership would be taxable as a corporation.  In such event, the
Company likely would cease to qualify as a REIT for a variety of reasons.
Furthermore, the imposition of a corporate income tax on the Operating
Partnership would reduce substantially the amount of Cash Available for
Distribution.  See "Federal Income Tax Considerations --Tax Aspects of the
Operating Partnership."

     ERISA RISKS.  The Employee Retirement Income Security Act of 1974, as
amended ("ERISA"), and section 4975 of the Code prohibit certain transactions
that involve (i) certain pension, profit-sharing, employee benefit, or
retirement plans or individual retirement accounts (each, a "Plan") and (ii) the
assets of a Plan.  A "party in interest" or "disqualified person" with respect
to a Plan will be subject to (x) an initial 5% excise tax on the amount involved
in any prohibited transaction involving the assets of the Plan and (y) an excise
tax equal to 100% of the amount involved if any prohibited transaction is not
corrected.  Consequently, the fiduciary of a Plan contemplating an investment in
the Shares should consider whether the Company, any other person associated with
the issuance of the Shares, or any affiliate of the foregoing is or might become
a "party in interest" or "disqualified person" with respect to the Plan.  In
such a case, the acquisition or holding of Shares by or on behalf of the Plan
could be considered to give rise to a prohibited transaction under ERISA and the
Code.  See "ERISA Considerations--Employee Benefit Plans, Tax-Qualified
Retirement Plans, and IRAs" herein.

     Regulations of the Department of Labor that define "plan assets" (the "Plan
Asset Regulations") provide that in some situations, when a Plan acquires an
equity interest in an entity, the Plan's assets include both the equity interest
and an undivided interest in each of the underlying assets of the entity, unless
one or more exceptions specified in the Plan Asset Regulations are satisfied.
In such a case, certain transactions that the Company might enter into in the
ordinary course of its business and operations might constitute "prohibited
transactions" under ERISA and the Code.  The assets of the Company should not be
deemed to be "plan assets" of any Plan that invests in the Shares.  See "ERISA
Considerations --Status of the Company and the Operating Partnership under
ERISA."

                         INVESTOR SUITABILITY STANDARDS

     An investment in the Company involves significant risk.  An investment in
the Shares is suitable only for persons who have adequate financial means and
desire a relatively long-term investment with respect to which they do not
anticipate any need for immediate liquidity.

     If the investor is an individual (including an individual beneficiary of a
purchasing IRA), or if the investor is a fiduciary (such as a trustee of a trust
or corporate pension or profit sharing plan, or other tax-exempt organization,
or a custodian under a Uniform Gifts to Minors Act), such individual or
fiduciary, as the case may be, must represent that he meets certain
requirements, as set forth in the Subscription Agreement attached as Exhibit B
to this Prospectus, including the following:

     (i) that such individual (or, in the case of a fiduciary, that the
fiduciary account or the donor who directly or indirectly supplies the funds to
purchase the Shares) has a minimum annual gross income of $45,000 and a net
worth (excluding home, furnishings and automobiles) of not less than $45,000; or

     (ii) that such individual (or, in the case of a fiduciary, that the
fiduciary account or the donor who directly or indirectly supplies the funds to
purchase the Shares) has a net worth (excluding home, furnishings and
automobiles) of not less than $150,000.

     Under the laws of certain states, transferees will also be required to
comply with applicable standards, except for intra-family transfers and
transfers made by gift, inheritance or family dissolution.

     The minimum purchase is 100 Shares ($1,000) (except in certain states as
described below).  No transfers will be permitted of less than the minimum
required purchase, nor (except in very limited circumstances) may an investor
transfer, fractionalize or subdivide such Shares so as to retain less than such
minimum number thereof.  For purposes of satisfying the minimum investment
requirement for Retirement Plans, unless otherwise prohibited by state law, a
husband and wife may jointly contribute funds from their separate Individual
Retirement Accounts ("IRAs"), provided that each such contribution is made in
increments of at least $100.  It should be noted, however, that an investment in
the Company will not, in itself, create a Retirement Plan for any investor and
that, in order to create a Retirement Plan, an investor must comply with all
applicable provisions of the Code.  Except in Maine, Minnesota and Washington,
investors who have satisfied the minimum purchase requirements and have
purchased units in Prior Wells Public Programs may purchase less than the
minimum number of Shares set forth above, but in no event less than 10 Shares
($100).  The minimum purchase for New York investors is 250 Shares ($2,500),
however, the minimum investment for New York IRAs is 100 Shares ($1,000).  After
an investor has purchased the minimum investment, any additional investments
must be made in increments of at least 10 Shares ($100), except for (i) those
made by investors in Maine, who must still meet the minimum investment
requirement for Maine residents of $1,000 for IRAs and $2,500 for non-IRAs, (ii)
purchases of Shares pursuant to the Reinvestment Plan, which may be in lesser
amounts, and (iii) minimum purchase for Minnesota investors is 250 Shares
($2,500), however, the minimum investment for Minnesota IRAs and qualified plans
may be 200 Shares ($2,000).

     Various states have established suitability standards for individual
investors and subsequent transferees different from those set by the Company.
Those requirements are set forth below.

     ARIZONA, IOWA, MASSACHUSETTS, MISSOURI, NORTH CAROLINA AND TENNESSEE -- The
investor has either (i) a net worth (exclusive of home, furnishings, and
personal automobiles) of at least $60,000 and an annual gross income of at least
$60,000, or (ii) a net worth (exclusive of home, furnishings, and personal
automobiles) of at least $225,000.

     MAINE -- The investor has either (i) a net worth (exclusive of home,
furnishings, and personal automobiles) of at least $50,000 and an annual gross
income of at least $50,000, or (ii) a net worth (exclusive of home, furnishings,
and personal automobiles) of at least $200,000.

     MASSACHUSETTS -- The investor has either (i) a net worth (exclusive of
home, furnishings, and personal automobiles) of at least $100,000 and an annual
gross income of at least $100,000, or (ii) a net worth (exclusive of home,
furnishings, and personal automobiles) of at least $250,000.

     NEW HAMPSHIRE -- The investor has either (i) a net worth (exclusive of
home, furnishings, and personal automobiles) of at least $125,000 and an annual
gross income of at least $50,000, or (ii) a net worth (exclusive of home,
furnishings, and personal automobiles) of at least $250,000.

     NEW YORK -- The investor has either (i) a net worth (exclusive of home,
furnishings, and personal automobiles) of at least $35,000 and an annual gross
income of at least $35,000, or (ii) a net worth (exclusive of home, furnishings,
and personal automobiles) of at least $100,000.

     OHIO -- The investor's investment in the Shares shall not exceed 10% of the
investor's net worth (exclusive of home, furnishings, and personal automobiles.)

     PENNSYLVANIA AND OREGON -- The investor has (i) a net worth (exclusive of
home, furnishings, and personal automobiles) of at least ten times the
investor's investment in the Company, and (ii) either (a) a net worth (exclusive
of home, furnishings, and personal automobiles) of at least $45,000 and an
annual gross income of at least $45,000, or (b) a net worth (exclusive of home,
furnishings, and personal automobiles) of at least $150,000.  Because the
minimum offering of Shares of the Company is less than $16,500,000, Pennsylvania
investors are cautioned to evaluate carefully the Company's ability to fully
accomplish its stated objectives and to inquire as to the current dollar volume
of the Company's subscription proceeds.

     NET WORTH IN ALL CASES EXCLUDES HOME, FURNISHINGS AND AUTOMOBILES.

     In order to assure adherence to the suitability standards described above,
requisite suitability standards must be met as set forth in the Subscription
Agreement and Subscription Agreement Signature Page (collectively, the
"Subscription Agreement"), which is attached as Exhibit B to this Prospectus.
The Company and each person selling Shares on behalf of the Company are required
to (i) make reasonable efforts to assure that each person purchasing Shares in
the Company is suitable in light of such person's age, educational level,
knowledge of investments, financial means and other pertinent factors and (ii)
maintain records for at least six years of the information used to determine
that an investment in Shares is suitable and appropriate for each investor.  The
agreements with the selling broker-dealers require such broker-dealers to (i)
make inquiries diligently as required by law of all prospective investors in
order to ascertain whether a purchase of the Shares is suitable for the
investor, and (ii) transmit promptly to the Company all fully completed and duly
executed Subscription Agreements.

(1) Excludes 1,500,000 Shares that may be sold pursuant to the Reinvestment
    Plan, but includes 600,000 Shares which may be issued pursuant to the
    Soliciting Dealer Warrants.

(2) The amounts shown for Gross Offering Proceeds do not reflect the possible
    discounts in commissions and other fees as described in "Plan Of
    Distribution."

(3) Includes Selling Commissions equal to 7% of aggregate Gross Offering
    Proceeds (which commissions may be reduced under certain circumstances)
    which are payable to the Dealer Manager, an Affiliate.  The Company also
    will issue to the Dealer Manager one Soliciting Dealer Warrant for every 25
    Shares sold.  The Dealer Manager, in its sole discretion, may reallow
    Selling Commissions of up to 7% of Gross Offering Proceeds and Soliciting
    Dealer Warrants to other broker-dealers participating in this Offering
    attributable to the Shares sold by them.  In no event shall the total
    underwriting compensation, including Selling Commissions, and expense
    reimbursements, exceed 7% of Gross Offering Proceeds, except for an
    additional Marketing and Due Diligence Fee equal to 2.5% of Gross Offering
    Proceeds which may be paid as a reimbursement of expenses incurred for
    marketing support (2%) and due diligence (.5%) purposes.  See "Plan of
    Distribution."

(4) These amounts represent the Advisor's best estimates of the Organization and
    Offering Expenses to be incurred in connection with the Offering.
    Organization and Offering Expenses consist of estimated legal, accounting,
    printing and other accountable offering expenses (other than Selling
    Commissions and the Marketing and Due Diligence Fee).  The Advisor and other
    Affiliates will be responsible for the payment of Organization and Offering
    Expenses (other than Selling Commissions and the marketing support and due
    diligence reimbursement fee) to the extent they exceed 3% of Gross Offering
    Proceeds, without recourse against or reimbursement by the Company.

(5) All or a portion of the Marketing and Due Diligence Fee may be reallowed to
    the non-affiliated Dealers which will assist the Dealer Manager in the
    distribution of Shares (the "Soliciting Dealers") for bona fide due
    diligence expenses.  Up to .5% of the Marketing and Due Diligence Fee may be
    paid as a reimbursement of due diligence expenses and up to 2% of the
    Marketing and Due Diligence Fee may be paid as a reimbursement of marketing
    support expenses in connection with the Offering.

(6) Until required in connection with the acquisition and development of
    properties, substantially all of the net proceeds of the Offering and,
    thereafter, the working capital reserves of the Company, may be invested in
    short-

     term, highly-liquid investments including government obligations, bank
     certificates of deposit, short-term debt obligations and interest-bearing
     accounts.

(7)  The Company will pay Acquisition and Advisory Fees to the Advisor or other
     Affiliates in connection with the acquisition of properties up to a maximum
     amount of 3% of Gross Offering Proceeds.  Acquisition and Advisory Fees do
     not include Acquisition Expenses.

(8)  Includes legal fees and expenses, travel and communication expenses, costs
     of appraisals, nonrefundable option payments, accounting fees and expenses,
     title insurance premiums and other closing costs and miscellaneous expenses
     relating to the selection, acquisition and development of properties that
     ultimately are not acquired by the Company. With respect to successful
     acquisitions, such costs generally will be included in the purchase price
     of the applicable property. It is anticipated that substantially all of
     such items will be directly related to the acquisition of specific
     properties and will be capitalized rather than currently deducted by the
     Company.

(9)  Because the vast majority of leases for the properties acquired by the
     Company will provide for tenant reimbursement of operating expenses, it is
     not anticipated that a permanent reserve for maintenance and repairs of the
     Company's properties will be established.  However, to the extent that the
     Company has insufficient funds for such purposes, the Company may apply an
     aggregate amount of up to 1% of Gross Offering Proceeds for maintenance and
     repairs of the Company's properties.  The Company also may, but is not
     required to, establish reserves from Gross Offering Proceeds, out of cash
     flow generated by operations properties or out of Nonliquidating Net Sale
     Proceeds.

(10) Includes amounts anticipated to be invested in properties net of fees and
     expenses.  It is estimated that approximately 84% of the proceeds of this
     Offering will be used to acquire properties.

(1)  Assumes that the maximum number of 15,000,000 Shares is sold (excluding any
     Shares sold pursuant to the Reinvestment Plan).

(2)  The Company may not make reimbursements to any entity for operating
     expenses in excess of 2% of Average Invested Assets or 25% of Net Income
     for such year.

     In addition, the Advisor and its Affiliates will be reimbursed only for the
actual cost of goods, services and materials used for or by the Company as set
forth in Section 10 of the Advisory Agreement.  The Advisor may be reimbursed
for the administrative services, including personnel costs, necessary to the
prudent operation of the Company, provided that the reimbursement shall be at
the lower of the Advisor's actual cost or the amount the Company would be
required to pay to independent parties for comparable administrative services in
the same geographic location.  No payment or reimbursement will be made for
services or personnel costs for which the Advisor is entitled to compensation by
way of a separate fee.  If the Subordinated Incentive Fee is paid to the
Advisor, no other performance fee will be paid to the Advisor; if the
Subordinated Participation Fee is paid to the Advisor, no Net Sales Proceeds
will be paid to the Advisor.

     Since the Advisor and its Affiliates are entitled to differing levels of
compensation for undertaking different transactions on behalf of the Company,
such as the property management fees for operating the Company's properties and
the subordinated participation in proceeds from the sale of the Company's
properties, the Advisor has the ability to affect the nature of the compensation
it receives by undertaking different transactions.  However, the Advisor is
obligated to exercise good faith and integrity in all its dealings with respect
to Company affairs pursuant to its fiduciary duties to the shareholders.  See
"The Advisor and the Advisory Agreement."  As noted above, there are ceilings on
certain categories of fees or expenses payable to the Advisor and its
Affiliates.  Because these fees or expenses are payable only with respect to
certain transactions or services, they may not be recovered by the Advisor or
their Affiliates by reclassifying them under a different category.  The Company
may not make reimbursements to any entity for operating expenses in excess of 2%
of Average Invested Assets or 25% of Net Income for such year.

                             CONFLICTS OF INTEREST

     The Company is subject to various conflicts of interest arising out of its
relationship with the Advisor and its Affiliates, including conflicts related to
the arrangements pursuant to which the Advisor and its Affiliates will be
compensated by the Company.  See "Management."

     The following chart indicates the relationship between Wells Real Estate
Funds, Inc., the parent corporation of the Advisor and the Affiliates of the
Advisor which will be providing services to the Company.

INTERESTS IN OTHER COMPANIES

     The Advisor and its Affiliates are also general partners of other real
estate limited partnerships, including partnerships which have investment
objectives substantially identical to those of the Company, and it is expected
that they will organize other such partnerships in the future.

     As described in the "Prior Performance Summary," the Advisor and its
Affiliates have sponsored the following twelve public partnerships with
substantially identical investment objectives as those of the Company: (i) Wells
Real Estate Fund I ("Wells Fund I"), (ii) Wells Real Estate Fund II ("Wells Fund
II"), (iii) Wells Real Estate Fund II-OW ("Wells Fund II-OW"), (iv) Wells Real
Estate Fund III, L.P. ("Wells Fund III"), (v) Wells Real Estate Fund IV, L.P.
("Wells Fund IV"), (vi) Wells Real Estate Fund V, L.P. ("Wells Fund V"), (vii)
Wells Real Estate Fund VI, L.P. ("Wells Fund VI"), (viii) Wells Real Estate Fund
VII, L.P. ("Wells Fund VII"), (ix) Wells Real Estate Fund VIII, L.P. ("Wells
Fund VIII"), (x) Wells Real Estate Fund IX, L.P. ("Wells Fund IX"), (xi) Wells
Real Estate Fund X, L.P. ("Wells Fund X") and Wells Real Estate Fund XI, L.P.
("Wells Fund XI").  All of the proceeds of the offerings of Wells Fund I, Wells
Fund II, Wells Fund II-OW, Wells Fund III, Wells Fund IV, Wells Fund V and Wells
Fund VI available for investment in real properties have been invested.  In
addition, all of the proceeds of the offering of Wells Fund VII available for
investment in real properties have been invested in properties.  In addition,
all of the proceeds of the offering of Wells Fund VIII available for investment
in real properties have been either invested or are committed for investment in
properties.  As of August 31, 1997, approximately 74% and 50% of the proceeds of
the offerings of Wells Fund IX and Wells Fund X, respectively, available for
investment in real properties had either been invested in properties or were
committed for investment in properties.  Wells Fund XI began to offer its
securities in January 1998.

     The Advisor also may be subject to potential conflicts of interest at such
time as the Company wishes to acquire a property that also would be suitable for
acquisition by an Affiliate of the Advisor.  Affiliates of the Advisor serve as
Directors of the Company, and, in this capacity, have a fiduciary obligation to
act in the best interest of the

                                       21
<PAGE>
 
stockholders of the Company and, as general partners or directors of the Prior
Wells Public Programs, to act in the best interests of the partners in other
programs with investments that may be similar to those of the Company and will
use their best efforts to assure that the Company will be treated as favorably
as any such other program. See "Management-- Fiduciary Responsibility of the
Board of Directors." In addition, the Company has developed procedures to
resolve potential conflicts of interest in the allocation of properties between
the Company and certain of its Affiliates. See "Certain Conflict Resolution
Procedures" below. The Company will supplement this Prospectus during the
Offering period to disclose the acquisition of a material property at such time
as the Advisor believes that a reasonable probability exists that the Company
will acquire a property, including an acquisition from the Advisor or its
Affiliates.

OTHER ACTIVITIES OF THE ADVISOR AND ITS AFFILIATES

     The Company will rely on the Advisor for the day-to-day operation of the
Company and the management of its assets.  As a result of its interests in other
partnerships and the fact that it has also engaged and will continue to engage
in other business activities, the Advisor and its Affiliates and certain of the
Directors will have conflicts of interest in allocating their time between the
Company and other partnerships and activities in which they are involved.
However, the Advisor believes that it and its Affiliates have sufficient
personnel to discharge fully their responsibilities to all partnerships and
ventures in which they are involved.

     The Company may (i) purchase or lease any property in which the Advisor or
any of its Affiliates have an interest, (ii) temporarily enter into contracts
relating to investment in properties to be assigned to the Company prior to
closing or may purchase property in their own name and temporarily hold title
for the Company, and (iii) enter into joint ventures with Affiliates of the
Advisor to acquire properties held by such Affiliates, provided that in any case
such transaction shall be made upon a finding by a majority of Directors
(including a majority of Independent Directors) not otherwise interested in the
transaction that such transaction is competitive and commercially reasonable to
the Company and at a price to the Company no greater than the cost of the asset
to the Advisor or such Affiliate (including acquisition and carrying costs), or,
if the price to the Company is in excess of such cost, that substantial
justification for such excess exists and such excess is reasonable and only if
the possibility of such acquisition(s) is disclosed, and there is appropriate
disclosure of the material facts concerning each such investment.  In no event
shall the cost of such asset to the Company exceed its current appraised value.
The Advisor or such Affiliate may not hold title to any such property on behalf
of the Company or an Affiliated joint venture for more than 12 months, and
further the Advisor or its Affiliates shall not sell property to the Company or
an Affiliated joint venture if the cost of the property exceeds the funds
reasonably anticipated to be available for the Company to purchase any such
property, and that all profits and losses during the period any such property is
held by the Advisor or the Affiliate will accrue to the Company or the
Affiliated joint venture, as applicable.  In no event may the Company (i) sell
or lease real property to the Advisor or any of its Affiliates (unless a
majority of the Independent Directors determine that the transaction is fair and
reasonable to the Company); (ii) loan Company funds to the Advisor or any of its
Affiliates; (iii) obtain appraisals of real properties from the Advisor or any
of their Affiliates; or (iv) enter into agreements with the Advisor or its
Affiliates for the provision of insurance covering the Company or any property
owned by the Company.

COMPETITION

     Conflicts of interest will exist to the extent that the Company may acquire
properties in the same geographic areas where other properties owned by the
Advisor and its Affiliates are located.  In such a case, a conflict could arise
in the leasing of the Company's properties in the event that the Company and
another program managed by the Advisor or its Affiliates were to compete for the
same tenants in negotiating leases, or a conflict could arise in connection with
the resale of the Company's properties in the event that the Company and another
program managed by the Advisor or its Affiliates were to attempt to sell similar
properties at the same time.  Conflicts of interest may also exist at such time
as the Company or Affiliates of the Advisor managing property on behalf of the
Company seek to employ developers, contractors or building managers as well as
under other circumstances.  The Advisor will seek to reduce conflicts relating
to the employment of developers, contractors or building managers by making
prospective employees aware of all such properties seeking to employ such
persons.  In addition, the Advisor will seek to reduce conflicts which may arise
with respect to properties available for sale or rent by making prospective
purchasers or lessees aware of all such properties.  However, these conflicts
cannot be fully avoided in that the Advisor may establish differing compensation
arrangements for employees at different properties or differing terms for
resales or leasing of the various properties.

                                       22
<PAGE>
 
AFFILIATED DEALER MANAGER

     Because the Dealer Manager is an Affiliate of the Advisor, the Company will
not have the benefit of an independent due diligence review and investigation of
the type normally performed by an unaffiliated, independent underwriter in
connection with the offering of securities.  See "Plan of Distribution."

AFFILIATED PROPERTY MANAGER

     Since it is anticipated that the Company's properties will be managed and
leased by the Management Company, an Affiliate of the Advisor, the Company will
not have the benefit of independent property management.  See "Management
Compensation."

AFFILIATED DEVELOPER

     It is expected that Wells Development, an Affiliate of the Advisor, will
serve as the developer of certain unimproved properties acquired by the Company,
but will not receive any profit from the development of such properties.

LACK OF SEPARATE REPRESENTATION

     Hunton & Williams is counsel to the Company, the Advisor, the Dealer
Manager and their Affiliates in connection with this Offering and may in the
future act as counsel to the Company, the Advisor, the Dealer Manager and their
Affiliates.  There is a possibility that in the future the interests of the
various parties may become adverse.  In the event that a dispute were to arise
between the Company, the Advisor, the Dealer Manager or their Affiliates, the
Advisor will cause the Company to retain separate counsel for such matters as
and when appropriate.

JOINT VENTURES WITH AFFILIATES OF THE ADVISOR

     The Company is likely to enter into one or more joint venture agreements
with Affiliates of the Advisor for the acquisition, development or improvement
of properties.  See "Investment Objectives and Criteria--Joint Venture
Investments."  The Advisor and its Affiliates may have conflicts of interest in
determining which partnerships should enter into any joint venture agreement.
Should any such joint venture be consummated, the Advisor may face a conflict in
structuring the terms of the relationship between the interest of the Company
and the interest of the affiliated co-venturer.  Since the Advisor and its
Affiliates will control both the Company and the affiliated co-venturer,
agreements and transactions between the co-venturers with respect to any such
joint venture will not have the benefit of arm's-length negotiation of the type
normally conducted between unrelated co-venturers.

RECEIPT OF FEES AND OTHER COMPENSATION BY ADVISOR AND AFFILIATES

     Company transactions involving the purchase and sale of the Company's
properties may result in the receipt of commissions, fees and other compensation
by the Advisor and its Affiliates, including Acquisition and Advisory Fees,
property management and leasing fees, real estate brokerage commissions, and
participation in distributions of Nonliquidating Net Sale Proceeds and
Liquidating Distributions.  However, the fees and compensation payable to the
Advisor and its Affiliates relating to sale of the Company's properties are
subordinated to the return to the shareholders of their Invested Capital plus
cumulative returns thereon.  Subject to the oversight of the Board of Directors,
the Advisor has considerable discretion with respect to all decisions relating
to the terms and timing of all Company transactions.  Therefore, the Advisor may
have conflicts of interest concerning certain actions taken on behalf of the
Company, particularly due to the fact that such fees will generally be payable
to the Advisor and its Affiliates regardless of the quality of the properties
acquired or the services provided to the Company.  See "Management
Compensation."

CERTAIN CONFLICT RESOLUTION PROCEDURES

     In order to reduce or eliminate certain potential conflicts of interest,
the Articles of Incorporation contain a number of restrictions relating to (i)
transactions between the Company and the Advisor or its Affiliates, (ii) certain

                                       23
<PAGE>
 
future offerings, and (iii) allocation of properties among certain affiliated
entities.  These restrictions include, among others, the following:

     1.  No goods or services will be provided by the Advisor or its Affiliates
to the Company except for transactions in which the Advisor or its Affiliates
provide goods or services to the Company in accordance with the Articles of
Incorporation which provides that a majority of the Directors (including a
majority of the Independent Directors) not otherwise interested in such
transactions must approve such transactions as fair and reasonable to the
Company and on terms and conditions not less favorable to the Company than those
available from unaffiliated third parties and not less favorable than those
available from the Advisor or its Affiliates in transactions with unaffiliated
third parties.

     2.  The Company will not purchase or lease properties in which the Advisor
or its Affiliates has an interest without the determination, by a majority of
the Directors (including a majority of the Independent Directors) not otherwise
interested in such transaction, that such transaction is competitive and
commercially reasonable to the Company and at a price to the Company no greater
than the cost of the asset to the Advisor or its Affiliate unless there is
substantial justification for any amount that exceeds such cost and such excess
amount is determined to be reasonable.  In no event shall the Company acquire
any such asset at an amount in excess of its appraised value.  The Company will
not sell or lease properties to the Advisor, Directors, or any Affiliates unless
a majority of the Directors (including a majority of the Independent Directors)
not interested in the transaction determine the transaction is fair and
reasonable to the Company.  The Company will not purchase or lease properties
from the Advisor, Directors, or any Affiliate without the approval of a majority
of the Directors (including the Independent Directors).

     3.  The Company will not make any loans to the Advisor, Directors or any
Affiliates.  The Advisor and its Affiliates will not make loans to the Company,
or to joint ventures in which the Company is a co-venturer, for the purpose of
acquiring properties.  Any loans to the Company by the Advisor, Directors, or
any Affiliates for other purposes must be approved by a majority of the
Directors (including a majority of the Independent Directors) not otherwise
interested in such transaction as fair, competitive, and commercially
reasonable, and no less favorable to the Company than comparable loans between
unaffiliated parties.  It is anticipated that the Advisor or its Affiliates
shall be entitled to reimbursement, at cost, for actual expenses incurred by
them on behalf of the Company or joint ventures in which the Company is a co-
venturer, subject to the 2%/25% Guidelines (2% of Average Invested Assets or 25%
of Net Income) described under "The Advisor and the Advisory Agreement--The
Advisory Agreement."

     4.  The Board of Directors and the Advisor have agreed that, in the event
than an investment opportunity becomes available which is suitable for both the
Company and a public or private entity with which the Advisor or its Affiliates
are affiliated, for which both entities have sufficient uninvested funds, then
the entity which has had the longest period of time elapse since it was offered
an investment opportunity will first be offered the investment opportunity.  An
investment opportunity will not be considered suitable for a program if the
requirements of Item 3 above could not be satisfied if the program were to make
the investment.  In determining whether or not an investment opportunity is
suitable for more than one program, the Board of Directors and the Advisor will
examine such factors, among others, as the cash requirements of each program,
the effect of the acquisition both on diversification of each program's
investments by types of commercial office properties and geographic area, and on
diversification of the tenants of its properties (which also may affect the need
for one of the programs to prepare or produce audited financial statements for a
property or a tenant), the anticipated cash flow of each program, the size of
the investment, the amount of funds available to each program, and the length of
time such funds have been available for investment.  If a subsequent
development, such as a delay in the closing of a property or a delay in the
construction of a property, causes any such investment, in the opinion of the
Board of Directors and the Advisor, to be more appropriate for an entity other
than the entity which committed to make the investment, however, the Advisor has
the right to agree that the other entity affiliated with the Advisor or its
Affiliates may make the investment.  It shall be the duty of the Directors
(including the Independent Directors) to insure that the method for the
allocation of the acquisition of properties by two or more programs of the same
Advisor seeking to acquire similar types of assets shall be reasonable.  The
Advisor and certain other Affiliates of the Company are affiliated with Wells
Fund X, a prior public program which terminated its offering in December 1997.
In addition, the Advisor and its Affiliates are affiliated with Wells Fund XI, a
publicly registered partnership that has not offered any securities to date.  As
of August 31, 1997, Wells Fund X had approximately $ 10,979,538 available for
investment.

                          SUMMARY OF REINVESTMENT PLAN

     The Company has adopted the Reinvestment Plan pursuant to which
stockholders may elect to have the full amount of their cash distributions from
the Company reinvested in additional Shares of the Company.  The following
discussion summarizes the principal terms of the Reinvestment Plan.  The
Reinvestment Plan and the Prospectus to be used in connection with certain sales
of the Company's stock are attached hereto as Exhibit C.

GENERAL

     Shareholders who have received a copy of this Prospectus and participate in
this Offering can elect to participate in and purchase Shares through the
Reinvestment Plan at any time and will not need to receive a separate prospectus
relating solely to the Reinvestment Plan.  A person who becomes a stockholder
otherwise than by participating in this Offering may purchase Shares through the
Reinvestment Plan only after receipt of a separate prospectus relating solely to
the Reinvestment Plan.

     The price per Share purchased pursuant to the Reinvestment Plan shall be
the Offering price, which is $10.00 per Share, until all of the Shares in this
Offering that are reserved for the Reinvestment Plan have been sold thereunder.
After such time, Shares for the Reinvestment Plan may be acquired by the Company
either through purchases on the open market and/or additional registrations
relating to the Reinvestment Plan, in either case at a per Share price equal to
the then-prevailing market price on the securities exchange or over-the-counter
market on which the Shares are listed at the date of purchase.  The Company is
unable to predict the effect which such a Listing would have on the price of the
Shares acquired through the Reinvestment Plan.

INVESTMENT OF DISTRIBUTIONS

     Distributions will be used to purchase Shares on behalf of the Participants
from the Company.  All such distributions shall be invested in Shares within 30
days after such payment date.  Any distributions not so invested will be
returned to Participants.

     At this time, Participants will not have the option to make voluntary
contributions to the Reinvestment Plan to purchase Shares in excess of the
amount of Shares that can be purchased with their distributions.  The Board of
Directors reserves the right, however, to amend the Reinvestment Plan in the
future to permit voluntary contributions to the Reinvestment Plan by
Participants, to the extent consistent with the Company's objective of
qualifying as a REIT.

PARTICIPANT ACCOUNTS, FEE, AND ALLOCATION OF SHARES

     For each Participant, the Company will maintain a record which shall
reflect for each fiscal quarter the distributions received by the Company on
behalf of such Participant.  Any interest earned on such Distributions will be
paid to the Company to defray certain costs relating to the Reinvestment Plan.

     The Company will use the aggregate amount of distributions to all
Participants for each fiscal quarter to purchase Shares for the Participants.
If the aggregate amount of distributions to Participants exceeds the amount
required to purchase all Shares then available for purchase, the Company will
purchase all available Shares and will return all remaining distributions to the
Participants within 30 days after the date such distributions are made.  The
purchased Shares will be allocated among the Participants based on the portion
of the aggregate distributions received on behalf of each Participant, as
reflected in the records maintained by the Company.  The ownership of the Shares
purchased pursuant to the Reinvestment Plan shall be reflected on the books of
the Company.

     Shares acquired pursuant to the Reinvestment Plan will entitle the
Participant to the same rights and to be treated in the same manner as those
purchased by the Participants in the Offering.  Accordingly, the Company will
pay the following commissions and fees in connection with Shares sold under the
Reinvestment Plan (until all such Shares are sold):  the Selling Commissions of
7% (subject to reduction under the circumstances provided under "The Offering--
Plan of Distribution"), the Marketing and Due Diligence Fee of 2.5%, and the
Acquisition and Advisory Fees of 3% of the purchase price of the Shares sold
pursuant to the Reinvestment Plan.  In connection with investments by

                                       25
<PAGE>
 
Ohio investors, the Company will pay only Acquisition and Advisory Fees of 3% of
the purchase price of the Shares sold pursuant to the Reinvestment Plan.
Thereafter, Acquisition and Advisory Fees will be paid by the Company only in
the event that proceeds of the sale of Shares are used to acquire properties. As
a result, aggregate fees payable to Affiliates of the Company will total between
9% and 12.5% of the proceeds of reinvested distributions, up to 7% of which may
be reallowed to Soliciting Dealers.

     The allocation of Shares among Participants may result in the ownership of
fractional Shares, computed to four decimal places.

REPORTS TO PARTICIPANTS

     Within 60 days after the end of each fiscal quarter, the Company will mail
to each Participant a statement of account describing, as to such Participant,
the distributions reinvested during the quarter, the number of Shares purchased
during the quarter, the per Share purchase price for such Shares, the total
administrative charge paid by the Company on behalf of each Participant (see "--
Participant Accounts, Fees and Allocation of Shares" above), and the total
number of Shares purchased on behalf of the Participant pursuant to the
Reinvestment Plan.  See "--General" above.

     Tax information with respect to income earned on Shares under the
Reinvestment Plan for the calendar year will be sent to each participant by the
Company.

ELECTION TO PARTICIPATE OR TERMINATE PARTICIPATION

     Stockholders of the Company who purchase Shares in this Offering may become
Participants in the Reinvestment Plan by making a written election to
participate on their Subscription Agreements at the time they subscribe for
Shares.  Any other stockholder who receives a copy of this Prospectus or a
separate prospectus relating solely to the Reinvestment Plan and who has not
previously elected to participate in the Reinvestment Plan may so elect at any
time by completing the enrollment form attached to such prospectus or by other
appropriate written notice to the Plan Administrator or Company of such
stockholder's desire to participate in the Reinvestment Plan.  Participation in
the Reinvestment Plan will commence with the next distribution made after
receipt of the Participant's notice, provided it is received at least ten days
prior to the record date for such distribution.  Subject to the preceding
sentence, the election to participate in the Reinvestment Plan will apply to all
distributions attributable to the fiscal quarter in which the stockholder made
such written election to participate in the Reinvestment Plan and to all fiscal
quarters thereafter, whether made (i) upon subscription or subsequently for
stockholders who participate in this offering, or (ii) upon receipt of a
separate prospectus relating solely to the Reinvestment Plan for stockholders
who do not participate in this offering.  Participants will be able to terminate
their participation in the Reinvestment Plan at any time without penalty by
delivering written notice to the Plan Administrator or Company no less than ten
days prior to the next record date.  The Company may also terminate the
Reinvestment Plan for any reason at any time, upon 10 days' prior written notice
to all Participants.

     A Participant who chooses to terminate participation in the Reinvestment
Plan must terminate his or her entire participation in the Reinvestment Plan and
will not be allowed to terminate in part.  If the Reinvestment Plan is
terminated, the Company will update its stock records to account for all whole
shares purchased by the participant(s) in the Plan, and if any fractional shares
exist, the Company may either (a) send you a check in payment for any fractional
shares in your account based in the then-current market price for the shares, or
(b) credit your stock ownership account with any such fractional shares. There
are no fees associated with a Participant's terminating his interest in the
Reinvestment Plan or the Company's termination of the plan.  A Participant in
the Reinvestment Plan who terminates his interest in the Reinvestment Plan will
be allowed to participate in the Reinvestment Plan again by notifying the
Company and completing any required forms.

     The Board of Directors reserves the right to prohibit Qualified Plans from
participating in the Reinvestment Plan if such participation would cause the
underlying assets of the Company to constitute "plan assets" of Qualified Plans.
See "Federal Income Tax Considerations --Taxation of Tax-Exempt Shareholders."

FEDERAL INCOME TAX CONSIDERATIONS

     Stockholders subject to federal income taxation who elect to participate in
the Reinvestment Plan will incur a tax liability for distributions allocated to
them even though they have elected not to receive their distributions in cash
but rather to have their distributions held pursuant to the Reinvestment Plan.
Specifically, stockholders will be treated as if they have received the
distribution from the Company and then applied such Distribution to purchase
Shares in the Reinvestment Plan.  A stockholder designating a distribution for
reinvestment will be taxed on the amount of such distribution as ordinary income
to the extent such distribution is from current or accumulated earnings and
profits, unless the Company has designated all or a portion of the distribution
as a capital gain dividend.  In such case, such designated portion of the
distribution will be taxed as long-term capital gain.

AMENDMENTS AND TERMINATION

     The Company reserves the right to amend any aspect of the Reinvestment Plan
without the consent of stockholders, provided that notice of the amendment is
sent to Participants at least 30 days prior to the effective date thereof.  The
Company also reserves the right to terminate the Reinvestment Plan for any
reason at any time by ten days' prior written notice of termination to all
Participants.  The Company may terminate a Participant's participation in the
Plan immediately if in the Company's judgment such Participant's participation
jeopardizes in any way the Company's status as a real estate investment trust.

                            SHARE REPURCHASE PROGRAM

     The Share Repurchase Program ("SRP") may, subject to certain restrictions,
provide eligible stockholders with limited, interim liquidity by enabling them
to sell Shares back to the Company at a price during the period of this Offering
equal to $8.40 per Share.  After the Offering, the price per Share pursuant to
the SRP will be set from time to time by the Board of Directors in its sole
discretion.  In such cases, the Board of Directors will consider the Company's
net asset value, recent comparable offerings and other factors which the Board
of Directors, in its sole discretion, deems relevant.  Repurchase prices are
expected to be available on the Company's Internet/World Wide Web site
(www.wellsref.com), and will be given by telephone upon request.

     Repurchases under the SRP, when done, will be made quarterly by the Company
in its sole discretion on a first-come, first-served basis, and will be limited
in the following ways:  (i) not more than $500,000 worth of the outstanding
Shares will be repurchased in any given year; and (ii) the funds available for
repurchase will be limited to available proceeds received by the Company from
the sale of Shares under the Reinvestment Plan.  The determination of available
funds from sales under the Reinvestment Plan and the decision to repurchase
Shares will be at the sole discretion of the Board.  In making this
determination, the Board will consider the need to use proceeds from the Share
sales under the Reinvestment Plan for investment in additional properties, or
for maintenance or repair of existing properties.  Such property-related uses
will have priority over the need to allocate funds to the SRP.  To be eligible
to offer Shares for purchase to the SRP, the stockholder must have beneficially
held the Shares for at least one year.

     The Company cannot guarantee that funds will be available for repurchase.
If no funds are available for the SRP at the time when repurchase is requested,
the stockholder could: (i) withdraw his request for repurchase; or (ii) ask that
the Company honor the request at such time, if any, when funds are available.
Such pending requests will be honored on a first-come, first-served basis.
There is no requirement that stockholders sell their Shares to the Company.  The
SRP is only intended to provide interim liquidity for stockholders until a
secondary market develops for the Shares.  No such market presently exists and
no assurance can be given that one will develop.  The SRP will exist during the
Offering period and will be terminated following the close of the Offering
period upon the Listing.

     Shares purchased by the Company under the SRP will be canceled, and will
have the status of authorized but unissued Shares.  Shares acquired by the
Company through the SRP will not be reissued unless they are first registered
with the Commission under the Act and under appropriate state securities laws or
otherwise issued in compliance with such laws.

                           PRIOR PERFORMANCE SUMMARY

     THE INFORMATION PRESENTED IN THIS SECTION REPRESENTS THE HISTORICAL
EXPERIENCE OF REAL ESTATE PROGRAMS MANAGED BY THE ADVISOR AND ITS AFFILIATES.
INVESTORS IN THE COMPANY SHOULD NOT ASSUME THAT THEY WILL EXPERIENCE RETURNS, IF
ANY, COMPARABLE TO THOSE EXPERIENCED BY INVESTORS IN SUCH PRIOR REAL ESTATE
PROGRAMS.

     The Advisor serves as a general partner of a total of twelve real estate
limited partnerships, eleven of which have completed offerings and one of which
has commenced but not completed its public offering.  A twelfth partnership is
in registration with the Commission and thus has not commenced.  These limited
partnerships and the year in which their offerings were completed are as
follows:

     1.   Wells Real Estate Fund I (1986)
     2.   Wells Real Estate Fund II (1988)
     3.   Wells Real Estate Fund II-OW (1988)
     4.   Wells Real Estate Fund III, L.P. (1990)
     5.   Wells Real Estate Fund IV, L.P. (1992)
     6.   Wells Real Estate Fund V, L.P. (1993)
     7.   Wells Real Estate Fund VI, L.P. (1994)
     8.   Wells Real Estate Fund VII, L.P. (1995)
     9.   Wells Real Estate Fund VIII, L.P. (1996)
     10.  Wells Real Estate Fund IX, L.P. (1996)
     11.  Wells Real Estate Fund X, L.P. (1997)
     12.  Wells Real Estate Fund XI, L.P. (offering commenced 12-31-97)

     The tables included in Exhibit A attached hereto set forth information as
of the dates indicated regarding certain of these prior programs as to (i)
experience in raising and investing funds (Table I); (ii) compensation to
sponsor (Table II); and (iii) annual operating results of prior programs (Table
III).  No information is given as to results of completed programs or sales or
disposals of property because, to date, none of the prior programs have sold any
of their properties.

PRIOR WELLS PUBLIC PROGRAMS

     The Advisor and its Affiliates sponsored the Prior Wells Public Programs,
all of which were offered on an unspecified property or "blind pool" basis.  The
total amount of funds raised from investors in the offerings of the Prior Wells
Public Programs, as of August 31, 1997, was approximately $257,000,000, and the
total number of investors in such partnerships was approximately 24,000.

     The investment objectives of the Prior Wells Public Programs are
substantially identical to the investment objectives of the Company.  All of the
proceeds of the offerings of Wells Fund I, Wells Fund II, Wells Fund II-OW,
Wells Fund III, Wells Fund IV, Wells Fund V, Wells Fund VI and Wells Fund VII
available for investment in real properties have been invested in properties.
In addition, all of the proceeds of the offering of Wells Fund VIII available
for investment in real properties have either been invested or are committed for
investment in properties.  As of August 31, 1997, approximately 74% and 50% of
the proceeds of the offerings of Wells Fund IX and Wells Fund X, respectively,
available for investment in real properties had either been invested in
properties or were committed for investment in properties.  Wells Fund XI
commenced its offering in January 1998 and thus has no funds available for
investment as of the date of this Prospectus.  For the fiscal year ended
December 31, 1996, approximately two-thirds of the aggregate gross rental income
of ten of these eleven publicly offered partnerships was derived from tenants
which are U.S. corporations, each of which the Company believes has net worth of
at least $100,000,000 or whose lease obligations are guaranteed by another
corporation with a net worth of at least $100,000,000.

                                       28
<PAGE>
 
     The Prior Wells Public Programs have acquired a total of 31 properties in
the following U.S. regions:  24 in the Southeast, one in the Northeast, two in
Southcentral, one in Northcentral and two in the West.  Each Prior Wells Public
Program has used only proceeds from its respective offering to finance its
acquisitions of properties.

     The real properties in which the Prior Wells Public Programs have invested
have experienced the same economic problems as other real estate investments in
recent years, including without limitation, general over-building and an excess
supply in many markets, along with increased operating costs and a general
downturn in the real estate industry.  As a result, certain of these public
partnerships have experienced increases in expenses and decreases in net income.
These fluctuations were primarily due to tenant turnover, resulting in increased
vacancies and the requirement to expend funds for tenant refurbishments, and
increases in administrative and other operating expenses.  See the Prior
Performance Tables included as Exhibit A hereto.  Additionally, while overall
occupancy rates have not decreased significantly at the properties owned by the
Prior Wells Public Programs, some of these properties have experienced high
tenant turnover, and the partnerships owning these properties have generally
been unable to raise rental rates and have been required to make expenditures
for tenant improvements and to grant free rent and other concessions in order to
attract new tenants.  Specifically, certain of the Prior Wells Public Programs
suffered decreases in net income during the real estate recession of the late
1980s and early 1990s, which decreases were generally attributable to the
overall downturn in the economy and in the real estate market in particular.
Because of the cyclical nature of the real estate market, such decreases in net
income of the public partnerships could occur at any time in the future when
economic conditions decline.  None of these prior programs has liquidated or
sold any of its real properties to date and, accordingly, no assurance can be
made that prior programs will ultimately be successful in meeting their
investment objectives.  See "Risk Factors."

     The aggregate dollar amount of the acquisition and development costs of the
properties purchased by the Prior Wells Public Programs, as of August 31, 1997,
was approximately $196,419,519, of which $4,254,000 (or approximately 2.2%) had
not yet been expended on the development of certain of the projects which are
still under construction.  Of the aggregate amount, approximately 65.0% was or
will be spent on acquiring or developing office buildings, and approximately
35.0% was or will be spent on acquiring or developing shopping centers.  Of the
aggregate amount, approximately 4% was or will be spent on new properties, 38%
on existing or used properties and 58% on construction properties.  Following is
a table showing a breakdown of the aggregate amount of the acquisition and
development costs of the properties purchased by the eleven Prior Wells Public
Programs as of October 31, 1997:

Type of Property              New          Existing    Construction
- ----------------             -----         --------    ------------ 
Office Buildings             4%             26%           35%
Shopping Centers             ---            11%           24%

     Wells Fund I terminated its offering on September 5, 1986, and received
gross proceeds of $35,321,000 representing subscriptions from 4,895 limited
partners.  $24,679,000 of the gross proceeds were attributable to sales of Class
A Limited Partnership Units ("Class A Units"), and $10,642,000 of the gross
proceeds were attributable to sales of Class B Limited Partnership Units ("Class
B Units" and, collectively with the Class A Units, "Units").  Limited partners

commercial office buildings in Atlanta, Georgia; (iii) a shopping center in
DeKalb County, Georgia; (iv) a shopping center in Knoxville, Tennessee; (v) a
shopping center in Cherokee County, Georgia; and (vi) a project consisting of
seven office buildings and a shopping center in Tucker, Georgia.  The prospectus
of Wells Fund I provided that the properties purchased by Wells Fund I would
typically be held for a period of eight to twelve years, but that the general
partners may exercise their discretion as to whether and when to sell the
properties owned by Wells Fund I and the partnership will have no obligation to
sell properties at any particular time.  Wells Fund I acquired its properties
between 1985 and 1987, and has not yet liquidated or sold any of its properties.

     Wells Fund II and Wells Fund II-OW terminated their offerings on September
7, 1988, and received aggregate gross proceeds of $36,870,250 representing
subscriptions from 4,659 limited partners.  $28,829,000 of the gross proceeds
were attributable to sales of Class A Units, and $8,041,250 of the gross
proceeds were attributable to sales of

                                       29

partners.  $19,661,770 of the gross proceeds were attributable to sales of Class
A Units, and $2,544,540 of the gross proceeds were attributable to sales of
Class B Units.  Limited partners in Wells Fund III have no right to change the
status of their Units from Class A to Class B or vice versa.  Wells Fund III

Houston, Texas; (ii) a restaurant in Roswell, Georgia; (iii) a combined retail
and office development in Roswell, Georgia; (iv) a two story office building in

partners.  $13,229,150 of the gross proceeds were attributable to sales of Class
A Units, and $385,505 of the gross proceeds were attributable to sales of Class

$15,209,666 of the gross proceeds were attributable to sales of Class A Units,
and $1,796,354 of the gross proceeds were attributable to sales of Class B
Units.  Limited partners in Wells Fund V who purchased Class B Units are
entitled to change the status of their Units to Class A, but limited partners
who purchased Class A Units are not entitled to change the status of their Units
to Class B.  After taking into effect conversion elections made by limited
partners subsequent to their subscription for Units, as of October 31, 1997,
$15,514,160 of Units of Wells Fund V were treated as Class A Units, and

     Potential investors are encouraged to examine the Prior Performance Tables

Registration Statement (which is not part of this Prospectus) gives certain

                                   MANAGEMENT

GENERAL

     The Company will operate under the direction of the Board of Directors, the
members of which are accountable to the Company as fiduciaries.  As required by
applicable regulations, a majority of the Independent Directors and a majority
of the Directors have reviewed and ratified the Articles of Incorporation and
have adopted the Bylaws.

     The Company currently has five Directors; it may have no fewer than three
Directors and no more than fifteen.  Directors will be elected annually, and
each Director will hold office until the next annual meeting of stockholders or
until his successor has been duly elected and qualified.  There is no limit on
the number of times that a Director may be elected to office.  Although the
number of Directors may be increased or decreased as discussed above, a decrease
shall not have the effect of shortening the term of any incumbent Director.

     Any Director may resign at any time and may be removed with or without
cause by the stockholders upon the affirmative vote of at least a majority of
all the Shares outstanding and entitled to vote at a meeting called for this
purpose.  The notice of such meeting shall indicate that the purpose, or one of
the purposes, of such meeting is to determine if a Director shall be removed.

FIDUCIARY RESPONSIBILITY OF THE BOARD OF DIRECTORS

     The Board of Directors will be responsible for the management and control
of the affairs of the Company; however, the Board of Directors will retain the
Advisor to manage the Company's day-to-day affairs and the acquisition and
disposition of investments, subject to the supervision of the Board of
Directors.

     The Directors are not required to devote all of their time to the Company
and are only required to devote such of their time to the affairs of the Company
as their duties require.  The Board of Directors will meet quarterly in person
or by telephone, or more frequently if necessary.  It is not expected that the
Directors will be required to devote a substantial portion of their time to
discharge their duties as directors.  Consequently, in the exercise of their
fiduciary responsibilities, the Directors will rely heavily on the Advisor.  In
this regard, the Advisor, in addition to the Directors, will have a fiduciary
duty to the Company.

     The Directors will monitor the administrative procedures, investment
operations, and performance of the Company and the Advisor to assure that such
policies are in the best interest of the stockholders and are fulfilled.  Until

                                       32
<PAGE>
 
modified by the Directors, the Company will follow the policies on investments
set forth in this Prospectus.  See "Investment Objectives and Policies."

     The Independent Directors are responsible for reviewing the fees and
expenses of the Company at least annually or with sufficient frequency to
determine that the total fees and expenses of the Company are reasonable in
light of the Company's investment performance, Net Assets, Net Income, and the
fees and expenses of other comparable unaffiliated real estate investment
trusts.  This determination shall be reflected in the minutes of the meetings of
the Board of Directors.  For purposes of this determination, Net Assets are the
Company's total assets (other than intangibles), calculated at cost before
deducting depreciation or other non-cash reserves, less total liabilities, and
computed at least quarterly on a basis consistently applied.  Such determination
will be reflected in the minutes of the meetings of the Board of Directors.  In
addition, a majority of the Independent Directors and a majority of Directors
not otherwise interested in the transaction must approve each transaction with
the Advisor or its Affiliates.  The Board of Directors also will be responsible
for reviewing and evaluating the performance of the Advisor before entering into
or renewing an advisory agreement.  The Independent Directors shall determine
from time to time and at least annually that compensation to be paid to the
Advisor is reasonable in relation to the nature and quality of services to be
performed and shall supervise the performance of the Advisor and the
compensation paid to it by the Company to determine that the provisions of the
Advisory Agreement are being carried out.  Specifically, the Independent
Directors will consider factors such as the capital, Net Assets and Net Income
of the Company, amount of the fee paid to the Advisor in relation to the size,
composition and performance of the Company's investments, the success of the
Advisor in generating appropriate investment opportunities, rates charged to
other comparable REITs and other investors by advisors performing similar
services, additional revenues realized by the Advisor and its Affiliates through
their relationship with the Company, whether paid by the Company or by others
with whom the Company does business, the quality and extent of service and
advice furnished by the Advisor, the performance of the investment portfolio of
the Company and the quality of the portfolio of the Company relative to the
investments generated by the Advisor for its own account.  Such review and
evaluation will be reflected in the minutes of the meetings of the Board of
Directors.  The Board of Directors shall determine that any successor Advisor
possesses sufficient qualifications to (i) perform the advisory function for the
Company and (ii) justify the compensation provided for in its contract with the
Company.

     The liability of the officers and Directors while serving in such capacity
is limited in accordance with the Articles of Incorporation, Bylaws and
applicable law.  See "Description of Capital Stock -- Limitation of Liability
and Indemnification."

Fees payable to the Advisor in connection with the selection or acquisition of
any property shall be reduced 

                                       37
<PAGE>
 
to the extent that, and if necessary to limit, the total compensation paid to
all persons involved in the acquisition of such property to the amount
customarily charged in arm's-length transactions by other persons or entities
rendering similar services as an ongoing public activity in the same
geographical location and for comparable types of properties, and to the extent
that other acquisition fees, finder's fees, real estate commissions, or other
similar fees or commissions are paid by any person in connection with the
transaction.

     If the Advisor or an Affiliate performs services that are outside of the
scope of the Advisory Agreement, compensation will be at such rates and in such
amounts as are agreed to by the Advisor and the Independent Directors of the
Company.

     Further, if Listing occurs, the Company automatically will become a
perpetual life entity.  At such time, the Company and the Advisor will negotiate
in good faith a fee structure appropriate for an entity with a perpetual life,
subject to approval by a majority of the Independent Directors.  In negotiating
a new fee structure, the Independent Directors shall consider all of the factors
they deem relevant.  These are expected to include, but will not necessarily be
limited to:  (i) the amount of the advisory fee in relation to the asset value,
composition, and profitability of the Company's portfolio; (ii) the success of
the Advisor in generating opportunities that meet the investment objectives of
the Company; (iii) the rates charged to other REITs and to investors other than
REITs by advisors that perform the same or similar services; (iv) additional
revenues realized by the Advisor and its Affiliates through their relationship
with the Company, including loan administration, underwriting or broker
commissions, servicing, engineering, inspection and other fees, whether paid by
the Company or by others with whom the Company does business; (v) the quality
and extent of service and advice furnished by the Advisor; (vi) the performance
of the investment portfolio of the Company, including income, conservation or
appreciation of capital, and number and frequency of problem investments; and
(vii) the quality of the portfolio of the Company in relationship to the
investments generated by the Advisor for its own account.  The Board of
Directors, including a majority of the Independent Directors, may not approve a
new fee structure that, in its judgment, is more favorable to the Advisor than
the current fee structure.

       The Company also shall pay the Advisor a deferred, subordinated real
estate disposition fee upon sale of one or more Properties, in an amount equal
to the lesser of (i) one-half (1/2) of a Competitive Real Estate Brokerage
Commission, or (ii) three percent (3%) of the sales price of such Property or
Properties.  In addition, the amount paid when added to the sums paid to
unaffiliated parties in such a capacity shall not exceed the lesser of the
Competitive Real Estate Brokerage Commission or an amount equal to 6% of the
sales price of such Property or Properties.  Payment of such fee shall be made
only if the Advisor provides a substantial amount of services in connection with
the Sale of a Property or Properties and shall be subordinated to receipt by the
stockholders of distributions equal to the sum of (i) their aggregate Common
Return and (ii) their aggregate invested capital.  If, at the time of a sale of
one or more Properties, payment of such disposition fee is deferred because the
subordination conditions have not been satisfied, then the disposition fee shall
be paid at such later time as the subordination conditions are satisfied.  Upon
Listing, if the Advisor has accrued but not been paid such real estate
disposition fee, then for purposes of determining whether the subordination
conditions have been satisfied, Stockholders will be deemed to have received a
Distribution in the amount equal to the product of the total number of Shares
outstanding and the average closing price of the Shares over a period, beginning
180 days after Listing, of 30 days during which the Shares are traded.

     The Advisory Agreement, which was entered into by the Company with the
unanimous approval of the Board of Directors, including the Independent
Directors, expires one year after the date hereof on January 30, 1999, subject
to successive one-year renewals upon mutual consent of the parties.  In the
event that a new Advisor is retained, the previous Advisor has agreed to
cooperate with the Company and the Directors in effecting an orderly transition
of the advisory functions.  The Board of Directors (including a majority of the
Independent Directors) shall approve a successor Advisor only upon a
determination that such successor Advisor possesses sufficient qualifications to
perform the advisory functions for the Company and that the compensation to be
received by the new Advisor pursuant to the new Advisory Agreement is justified.

     The Advisory Agreement may be terminated without cause or penalty by either
party, or by the mutual consent of the parties (by a majority of the Independent
Directors of the Company or a majority of the directors of the Advisor, as the
case may be), upon 60 days' prior written notice.  The Advisor shall be entitled
to receive all accrued but unpaid compensation and expense reimbursements in
cash within 30 days of the effective date of termination of the Advisory

                                       38
<PAGE>
 
Agreement.  All other amounts payable to the Advisor in the event of a
termination shall be evidenced by a promissory note and shall be payable from
time to time.

     The Advisor has the right to assign the Advisory Agreement to an Affiliate
subject to approval by the Independent Directors of the Company.  The Company
has the right to assign the Advisory Agreement to any successor to all of its
assets, rights, and obligations.

     The Advisor will not be liable to the Company or its stockholders or
others, except by reason of acts constituting bad faith, fraud, misconduct, or
negligence, and will not be responsible for any action of the Board of Directors
in following or declining to follow any advice or recommendation given by it.
The Company has agreed to indemnify the Advisor with respect to acts or
omissions of the Advisor undertaken in good faith, in accordance with the
foregoing standards and pursuant to the authority set forth in the Advisory
Agreement.  Any indemnification made to the Advisor may be made only out of the
net assets of the Company and not from stockholders.

                                WELLS MANAGEMENT

                       INVESTMENT OBJECTIVES AND CRITERIA

GENERAL

     The Company is a corporation that intends to elect to be taxed as a REIT
for federal income tax purposes.  The Company was organized to invest in
commercial real properties, including properties which are under development or
construction, are newly constructed or have been constructed and have operating
histories.  The Company's objectives are: (i) to maximize Cash Available for
Distribution; (ii) to preserve, protect and return the Invested Capital of the
shareholders; (iii) to realize capital appreciation upon the ultimate sale of
the Company's properties; and (iv) to provide shareholders with liquidity of
their investment, within 10 years after commencement of the Offering, through
either (a) the listing of the Shares, or (b) if Listing does not occur within
ten years following the commencement of the Offering, the dissolution of the
Company and the orderly liquidation of its assets.  No assurance can be given
that these objectives will be attained.

     Decisions relating to the purchase or sale of the Company's properties will
be made by the Advisor, subject to the oversight of the Board of Directors.  See
"The Advisor and the Advisory Agreement" for a description of the background and
experience of the Advisor.

ACQUISITION AND INVESTMENT POLICIES

     The Company will seek to invest substantially all of the net Offering
proceeds available for Investment in properties in the acquisition of commercial
real properties, which are under development or construction, are newly
constructed or which have been previously constructed and have operating
histories.  While not limited to such investments, the Advisor will generally
seek to invest in commercial properties such as office buildings, shopping
centers and industrial properties which are less than five years old, the space
in which has been leased or preleased to one or more large corporate tenants who
satisfy the Advisor' standards of creditworthiness.  Based on the Advisor's
prior experience with the Prior Wells Public Programs, the Company anticipates
that a majority of the tenants of the Company's properties will be U.S.
corporations (or other entities) each of which has a net worth in excess of
$100,000,000 or whose lease obligations are guaranteed by another corporation or
entity with a net worth in excess of $100,000,000.  The Company may, however,
invest in office buildings, shopping centers or industrial properties which are
not preleased to such tenants or in other types of commercial or industrial
properties such as hotels, motels, restaurants or business or industrial parks.
Notwithstanding the foregoing, under the REIT qualification rules, the Company
may not be actively engaged in the business of operating hotels, motels or
similar properties.

     While the Company will seek to invest in properties that will satisfy the
primary objective of providing distributions of current cash flow to investors,
due to the fact that a significant factor in the valuation of income-producing
real properties is their potential for future income, the Advisor anticipates
that the majority of properties 

                                       40
<PAGE>
 
acquired by the Company will satisfy both attributes of providing potential for
capital appreciation and providing distributions of current cash flow to
investors. To the extent feasible, the Advisor will strive to invest in a
diversified portfolio of properties that will satisfy the Company's investment
objectives of maximizing Cash Available for Distribution, preserving investors'
capital and realizing capital appreciation upon the ultimate sale of the
Company's properties.

     It is anticipated that approximately 84% of the Gross Proceeds of the
Offering will be used to acquire properties and the balance will be used to pay
various fees and expenses.  See "Estimated Use of Proceeds."

     The Company may not invest more than 10% of its total assets in Unimproved
Real Property.  A property which is expected to produce income within two years
of its acquisition will not be considered a non-income producing property.

     Investment in property generally will take the form of fee title or of a
leasehold estate having a term, including renewal periods, of at least 40 years,
and may be made either directly or indirectly through investments in joint
ventures, general partnerships, co-tenancies or other co-ownership arrangements
with the developers of the properties, Affiliates of the Advisor or other
persons.  See "Joint Venture Investments" below.  In addition, the Company may
purchase properties and lease them back to the sellers of such properties.
While the Advisor will use its best efforts to structure any such sale-leaseback
transaction such that the lease will be characterized as a "true lease" and so
that the Company will be treated as the owner of the property for federal income
tax purposes, no assurance can be given that the Service will not challenge such
characterization.  In the event that any such sale-leaseback transaction is
recharacterized as a financing transaction for federal income tax purposes,
deductions for depreciation and cost recovery relating to such property would be
disallowed or significantly reduced.  See "Federal Income Tax Considerations."

     The Company is not limited as to the geographic area where it may conduct
its operations, but the Advisor intends to cause the Company to invest primarily
in properties located in the United States.

     There are no specific limitations on the number or size of properties to be
acquired by the Company or on the percentage of net proceeds of this Offering
which may be invested in a single property.  The number and mix of properties
acquired will depend upon real estate and market conditions and other
circumstances existing at the time the Company is acquiring its properties and
the amount of the net proceeds of this Offering.

     In making investment decisions for the Company, the Advisor will consider
relevant real property and financial factors, including the location of the
property, its suitability for any development contemplated or in progress, its
income-producing capacity, the prospects for long-range appreciation, its
liquidity and income tax considerations.  In this regard, the Advisor will have
substantial discretion with respect to the selection of specific Company
investments.

     The Company will obtain independent appraisals for each property in which
it invests, and the purchase price of each such property will not exceed its
appraised value.  However, the Advisor and the Board of Directors will rely on
their own independent analysis and not on such appraisals in determining whether
to invest in a particular property.  It should be noted that appraisals are
estimates of value and should not be relied upon as measures of true worth or
realizable value.  Copies of these appraisals will be available for review and
duplication by shareholders at the office of the Company and will be retained
for at least five years.

     The Company's obligation to close the purchase of any investment will
generally be conditioned upon the delivery and verification of certain documents
from the seller or developer, including, where appropriate, plans and
specifications, environmental reports, surveys, evidence of marketable title
(subject only to such liens and encumbrances as are acceptable to the Advisor),
audited financial statements covering recent operations of any properties having
operating histories (unless such statements are not required to be filed with
the Securities and Exchange Commission and delivered to investors), title and
liability insurance policies and opinions of counsel in certain circumstances.
The Company will not close the purchase of any property unless and until it
obtains an environmental assessment (a minimum of a Phase I review) for each
property purchased and the Advisor is generally satisfied with the environmental
status of the property.

                                       41
<PAGE>
 
     The Company may also enter into arrangements with the seller or developer
of a property whereby the seller or developer agrees that if during a stated
period the property does not generate a specified cash flow, the seller or
developer will pay in cash to the Company a sum necessary to reach the specified
cash flow level, subject in some cases to negotiated dollar limitations.

     In determining whether to purchase a particular property, the Company may,
in accordance with customary practices, obtain an option on such property.  The
amount paid for an option, if any, is normally surrendered if the property is
not purchased and is normally credited against the purchase price if the
property is purchased.

     In purchasing, leasing and developing real properties, the Company will be
subject to risks generally incident to the ownership of real estate, including
changes in general economic or local conditions, changes in supply of or demand
for similar or competing properties in an area, changes in interest rates and
availability of permanent mortgage funds which may render the sale of a property
difficult or unattractive, and changes in tax, real estate, environmental and
zoning laws.  Periods of high interest rates and tight money supply may make the
sale of properties more difficult.  The Company may experience difficulty in
keeping the properties fully leased due to tenant turnover, general overbuilding
or excess supply in the market area.  Development of real properties is subject
to risks relating to the builders' ability to control construction costs or to
build in conformity with plans, specifications and timetables.  See "Risk
Factors--Real Estate Risks."

DEVELOPMENT AND CONSTRUCTION OF PROPERTIES

     The Company may invest substantially all of the net proceeds available for
Investment in properties on which improvements are to be constructed or
completed although the Company may not invest in excess of 10% of total assets
in properties which are not expected to produce income within two years of their
acquisition.  To help ensure performance by the builders of properties which are
under construction and completion of properties under construction, the Advisor
may rely upon the substantial net worth of the contractor or developer or a
personal guarantee accompanied by financial statements showing a substantial net
worth provided by an Affiliate of the person entering into the construction or
development contract, or, in certain circumstances, the Advisor may require an
adequate completion bond or performance bond.

     The Company may make periodic progress payments or other cash advances to
developers and builders of its properties prior to completion of construction
only upon receipt of an architect's certification as to the percentage of the
project then completed and as to the dollar amount of the construction then
completed.  The Company intends to use such additional controls on its
disbursements to builders and developers as it deems necessary or prudent.

     The Company may directly employ one or more project managers to plan,
supervise and implement the development of any Unimproved Real Properties which
it may acquire.  Such persons would be compensated directly by the Company and,
other than through such employment, will not be affiliated with the Advisor.

TERMS OF LEASES AND LESSEE CREDITWORTHINESS

     The terms and conditions of any lease entered into by the Company with
regard to a tenant may vary substantially from those described herein.  However,
a majority of leases are expected to be what is generally referred to as "triple
net" leases, which means that the lessee will be required to pay or reimburse
the Company for all real estate taxes, sales and use taxes, special assessments,
utilities, insurance and building repairs as well as lease payments.

     The Advisor has developed specific standards for determining the
creditworthiness of potential lessees of Company Properties.  While authorized
to enter into leases with any type of lessee, the Advisor anticipates that a
majority of the tenants of the Company Properties will be top U.S. corporations
or other entities each of which has a net worth in excess of $100,000,000 or
whose lease obligations are guaranteed by another corporation or entity with a
net worth in excess of $100,000,000.

                                       42
<PAGE>
 
BORROWING POLICIES

     The Company may incur indebtedness in connection with the development or
acquisition of properties, which indebtedness may be secured by one or more of
the Company's properties.  The Company also may borrow funds (a) for Company
operating purposes in the event of unexpected circumstances in which the
Company's working capital reserves and other cash resources available to the
Company become insufficient for the maintenance and repair of its properties or
for the protection or replacement of the Company's assets, and (b) in order to
finance improvement of and improvements to its properties, when the Advisor
deems such improvements to be necessary or appropriate to protect the capital
previously invested in the properties, to protect the value of the Company's
investment in a particular property, or to make a particular property more
attractive for sale or lease.  The aggregate borrowing of the Company, secured
and unsecured, shall be reasonable in relation to Net Assets of the Company and
shall be reviewed by the Board of Directors at least quarterly.  Such
indebtedness may be in the form of secured and unsecured bank borrowings, and
publicly and privately placed debt offerings.  Borrowings may be incurred
through either the Operating Partnership or the Company.  The Board of Directors
anticipates that the aggregate amount of any borrowing will not exceed 50% of
the aggregate value of the Company's aggregate properties, provided, however,
                                                           --------          
that such level may be exceeded on an individual property basis.

JOINT VENTURE INVESTMENTS

     The Company is likely to enter into one or more joint ventures with
Affiliated entities for the acquisition, development or improvement of
properties, under the conditions described below.  The Company may invest some
or all of the proceeds of the Offering in such joint ventures.  In this
connection, the Company may enter into joint ventures with future programs
sponsored by the Advisor or its Affiliates or Prior Wells Public Programs.  The
Advisor also has the authority to enter into joint ventures, general
partnerships, co-tenancies and other participations with real estate developers,
owners and others for the purpose of developing, owning and operating properties
in accordance with the Company's investment policies.  See "Risk Factors" and
"Conflicts of Interest."  In determining whether to invest in a particular joint
venture, the Advisor will evaluate the real property which such joint venture
owns or is being formed to own under the same criteria described herein for the
selection of real property investments of the Company.  The Company shall not
invest in joint ventures with the Advisor, any Directors or any Affiliate
thereof, unless a majority of the Directors (including a majority of the
Independent Directors) not otherwise interested in such transactions, approve
the transaction as being fair and reasonable to the Company and on substantially
the same terms and conditions as those received by other joint venturers.  See
"--Acquisition and Investment Policies," "--Development and Construction of
Properties," "--Terms of Leases and Lessee Creditworthiness," and "--Borrowing
Policies."

     At such time as the Advisor believes that a reasonable probability exists
that the Company will enter into a joint venture with a Prior Wells Public
Program for the acquisition or development of a specific material property, this
Prospectus will be supplemented to disclose the terms of such proposed
investment transaction.  Based upon the Advisor's experience, in connection with
the development of a property which is currently owned by a Prior Wells Public
Program, this would normally occur upon the signing of legally binding leases
with one or more major tenants for commercial space to be developed on such
property, but may occur before or after any such signing, depending upon the
particular circumstances surrounding each potential investment.  It should be
understood that the initial disclosure of any such proposed transaction cannot
be relied upon as an assurance that the Company will ultimately consummate such
proposed transaction nor that the information provided in any such supplement to
this Prospectus concerning any such proposed transaction will not change after
the date of the supplement.

     The Company may enter into a partnership, joint venture or co-tenancy with
unrelated parties if (i) the management of such partnership, joint venture or
co-tenancy is under the control of the Company; (ii) the Company, as a result of
such joint ownership or partnership ownership of a property, is not charged,
directly or indirectly, more than once for the same services; (iii) the joint
ownership, partnership or co-tenancy agreement does not authorize or require the
Company to do anything as a partner, joint venturer or co-tenant with respect to
the property which the Company or the Advisor could not do directly because of
the Company's Articles of Incorporation; and (iv) the Advisor and its Affiliates
are prohibited from receiving any compensation, fees or expenses which are not
permitted to be paid under the Advisory Agreement.  In the event that any such
co-ownership arrangement contains a provision giving each party a right of first
refusal to purchase the other party's interest, the Company may not have
sufficient capital to finance any such buy-out.  See "Risk Factors."

                                       43
<PAGE>
 
     The Company intends to enter into joint ventures with other publicly
registered Affiliated entities for the acquisition of properties, but may only
do so provided that (i) each such co-venturer has substantially identical
investment objectives as those of the Company; (ii) the Company, as a result of
such joint ownership or partnership ownership of a property, is not charged,
directly or indirectly, more than once for the same services; (iii) compensation
payable to the Company by such Affiliate is substantially identical to that
payable to the Advisor by the Company; (iv) the Company will have a right of
first refusal to buy if such co-venturer elects to sell its interest in the
property held by the joint venture; and (v) the investment by the Company and
such Affiliate are on substantially the same terms and conditions, and each such
entity's ownership interest in such joint venture or partnership shall be based
upon the respective proportion of funds invested in such joint venture or
partnership by the Company and such Affiliate.  In the event that the co-
venturer were to elect to sell property held in any such joint venture, however,
the Company may not have sufficient funds to exercise its right of first refusal
to buy the other co-venturer's interest in the property held by the joint
venture.  In the event that any joint venture with an Affiliated entity holds
interests in more than one property, the interest in each such property may be
specially allocated based upon the respective proportion of funds invested by
each co-venturer in each such property.  Entering into such joint ventures with
Affiliated entities will result in certain conflicts of interest.  See "Risk
Factors" and "Conflicts of Interest--Joint Ventures with Affiliates of the
Advisor."

OTHER POLICIES

     The Company will not invest as a limited partner in limited partnerships,
except such investments acquired through the Operating Partnership.  The Company
may in the future issue senior securities.  The Company may, pursuant to the
Reinvestment Plan, repurchase or otherwise reacquire its common stock.

     Except in connection with sales of properties by the Company where purchase
money obligations may be taken by the Company as partial payment, the Company
will not make loans to any person, nor will the Company underwrite securities of
other issuers, in exchange for property, or invest in securities of other
issuers for the purpose of exercising control.  Notwithstanding the foregoing,
the Company may invest in joint ventures or partnerships as described above and
in a corporation where real estate is the principal asset and its acquisition
can best be effected by the acquisition of the stock of such corporation,
subject to the limitations set forth below.

     The Company will not: (i) make or invest in real estate mortgage loans
(except in connection with the sale or other disposition of a property); (ii)
make loans to the Advisor or other Affiliates, or to any director, officer or
principal of the Company or any of its Affiliates; (iii) invest in commodities
or commodity future contracts (does not apply to future contracts, when used
solely for hedging purposes in connection with the Company's ordinary business
of investing in real estate assets and mortgages); (iv) issue redeemable equity
securities; (v) issue debt securities unless the historical debt service
coverage (in the most recently completed fiscal year), as adjusted for known
changes, is sufficient to properly service that higher level of debt; (vi) issue
options or warrants to purchase its Shares to the Advisor, Directors, or any
Affiliate thereof except on the same terms as such options or warrants may be
sold to the general public, any such options or warrants issued to the Advisor,
Directors, or any Affiliate shall not exceed an amount equal to 10% of the
outstanding Shares of the Company on the date of grant; (vii) issue its shares
on a deferred payment basis or other similar arrangement; (viii) invest in or
underwrite the securities of other issuers, including any publicly offered or
traded limited partnership interests, except for investments in joint ventures
as described herein, and except for permitted temporary investments pending
utilization of Company funds, provided that following one year after the
commencement of operations of the Company no more than 45% of the value of the
Company's total assets (exclusive of Government securities and cash items) will
consist of, and no more than 45% of the Company's net income after taxes (for
the last four fiscal quarters combined) will be derived from, securities other
than (A) Government securities, or (B) securities in a corporation where real
estate is the principal asset and the acquisition of such real estate can best
be effected by the acquisition of the stock of such corporation, provided that
any such corporation is either (x) a corporation which is a majority owned
subsidiary of the Company and which is not an investment company as defined by
the Investment Company Act of 1940, as amended, or (y) a corporation which is
controlled primarily by the Company, through which corporation the Company
engages in the business of acquisition and operation of real estate and which is
not an investment company.

                           REAL PROPERTY INVESTMENTS

     As of the date of this Prospectus, the Company has not acquired nor
contracted to acquire any specific real properties.  The Advisor is continually
evaluating various potential property investments and engaging in discussions
and negotiations with sellers, developers and potential tenants regarding the
purchase and development of properties for the Company and prior programs.  At
such time during the negotiations for a specific property as the Advisor
believes that a reasonable probability exists that the Company will acquire such
property, this Prospectus will be supplemented to disclose the negotiations and
pending acquisition.  Based upon the Advisor's experience and acquisition
methods, this will normally occur on the signing of a legally binding purchase
agreement for the acquisition of a specific property, but may occur before or
after such signing or upon the satisfaction or expiration of major contingencies
in any such purchase agreement, depending on the particular circumstances
surrounding each potential investment.  A supplement to this Prospectus will
describe any improvements proposed to be constructed thereon and other
information considered appropriate for an understanding of the transaction.
Further data will be made available after any pending acquisition is
consummated, also by means of a supplement to this Prospectus, if appropriate.
IT SHOULD BE UNDERSTOOD THAT THE INITIAL DISCLOSURE OF ANY PROPOSED ACQUISITION
CANNOT BE RELIED UPON AS AN ASSURANCE THAT THE COMPANY WILL ULTIMATELY
CONSUMMATE SUCH PROPOSED ACQUISITION NOR THAT THE INFORMATION PROVIDED
CONCERNING THE PROPOSED ACQUISITION WILL NOT CHANGE BETWEEN THE DATE OF SUCH
SUPPLEMENT AND ACTUAL PURCHASE.

     It is intended that the proceeds of this Offering will be invested in
properties in accordance with the Company's investment policies.  Funds
available for Investment in properties which are not expended or committed to
the acquisition or development of specific real properties on or before the
later of the second anniversary of the effective date of the Registration
Statement or one year after the termination of the Offering and not reserved for
working capital purposes will be returned to the shareholders.

     The Company intends to obtain adequate insurance coverage for all
properties in which it invests.

                              DISTRIBUTION POLICY

REIT STATUS

     In order to qualify as a REIT for federal income tax purposes, among  other
things, the Company must make distributions each taxable year (not including any
return of capital for federal income tax purposes) equal to at least 95% of its
real estate investment trust taxable income, although the Board of Directors, in
its discretion, may increase that percentage as it deems appropriate.  See
"Federal Income Tax Considerations--Requirements for Qualification."  The
declaration of distributions is within the discretion of the Board of Directors
and depends upon the Company's Cash Available for Distribution, current and
projected cash requirements, tax considerations and other factors.

     The Company intends to make regular quarterly distributions to holders of
the Shares.  Distributions will be made to those stockholders who are
stockholders as of the record date selected by the Directors.  Distributions
will be declared monthly and paid on a quarterly basis during the Offering
period and declared and paid quarterly thereafter.  Generally, income
distributed to stockholders will not be taxable to the Company under federal
income tax laws if the Company distributes at least 95% of its annual taxable
income.  If Cash Available for Distribution is insufficient to pay such
distributions, the Company may obtain the necessary funds by borrowing, issuing
new securities, or selling assets.  These methods of obtaining funds could
affect future distributions by increasing operating costs.  To the extent that
distributions to stockholders exceed the Company's current and accumulated
earnings and profits, such amounts will constitute a return of capital for
federal income tax purposes, although such distributions will not reduce
stockholders' aggregate Invested Capital.

     Distributions will be made at the discretion of the Directors, depending
primarily on Cash Available for Distribution and the general financial condition
of the Company, subject to the obligation of the Directors to cause the Company
to qualify and remain qualified as a REIT for federal income tax purposes.  The
Company intends to increase distributions in accordance with increases in Cash
Available for Distribution.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS

     As of the date of this Prospectus, the Company had not yet commenced active
operations.  Subscription proceeds may be released to the Company as accepted
and applied to investment in properties and the payment or reimbursement of
Selling Commissions and other Organization and Offering Expenses.  See
"Estimated Use of Proceeds."  The Company will experience a relative increase in
liquidity as additional subscriptions for Shares are received, and a relative
decrease in liquidity as net Offering proceeds are expended in connection with
the acquisition, development and operation of properties.

     As of the initial date of this Prospectus, the Company has not entered into
any arrangements creating a reasonable probability that any specific property
will be acquired by the Company.  The number of Company properties to be
acquired by the Company will depend upon the number of Shares sold and the
resulting amount of the net proceeds available for investment in properties
available to the Company.  See "Risk Factors."

     The Company is not aware of any material trends or uncertainties, favorable
or unfavorable, other than national economic conditions affecting real estate
generally, which may be reasonably anticipated to have a material impact on
either capital resources or the revenues or income to be derived from the
operation of the Company's properties.

     Until required for the acquisition, development or operation of properties,
net Offering proceeds will be kept in short-term, liquid investments.  Because
the vast majority of leases for the properties acquired by the Company will
provide for tenant reimbursement of operating expenses, it is not anticipated
that a permanent reserve for maintenance and repairs of Company properties will
be established.  However, to the extent that the Company has insufficient funds
for such purposes, the Advisor may contribute to the Company an aggregate amount
of up to 1% of Gross Offering Proceeds for maintenance and repairs of the
Company's properties.  The Advisor also may, but is not required to, establish
reserves from Gross Offering Proceeds, out of cash flow generated by operating
properties or out of Nonliquidating Net Sale Proceeds.

                          DESCRIPTION OF CAPITAL STOCK

     The following summary of certain provisions of the Company's Articles of
Incorporation and Bylaws and Maryland law is subject to and qualified in its
entirety by reference to such documents, copies of which are Exhibits to the
Registration Statement of which this Prospectus is a part.

     Under its Articles of Incorporation, the Company has authority to issue a
total of 90,000,000 shares of capital stock, of which 40,000,000 shares are
designated as common stock, $.01 par value per share (the "Common Stock"),
5,000,000 shares of which are designated are preferred stock, $.01 par value per
share (the "Preferred Stock"), and 45,000,000 shares are designated as Shares-
in-Trust (as described in "-- Articles of Incorporation and Bylaw Provisions."

COMMON STOCK

     The holders of Shares are entitled to one vote per share on all matters
voted on by shareholders, including elections of directors.  Except as otherwise
required by law or provided in any resolution adopted by the Board of Directors
with respect to any series of Preferred Stock, the holders of such shares
exclusively possess all voting power.  The Articles of Incorporation do not
provide for cumulative voting in the election of directors.  Subject to any
preferential rights of any outstanding series of Preferred Stock, the holders of
Shares are entitled to such dividends as may be declared from time to time by
the Board of Directors from funds available therefor, and upon liquidation are
entitled to receive pro rata all assets of the Company available for
distribution to such holders.  All Shares issued in the Offering will be fully
paid and nonassessable and the holders thereof will not have preemptive rights.

                                       46
<PAGE>
 
PREFERRED STOCK

     The Articles of Incorporation authorize the Board of Directors to designate
and issue from time to time one or more classes or series of Preferred Stock
without stockholder approval.  The Board of Directors may determine the relative
rights, preferences and privileges of each class or series of Preferred Stock so
issued, which may be more beneficial than those of the Common Stock.  However,
the voting rights for each share of Preferred Stock shall not exceed voting
rights of the Common Stock.  The issuance of Preferred Stock could have the
effect of delaying or preventing a change in control of the Company.  The Board
of Directors has no present plans to issue any Preferred Stock, but may
nevertheless do so in the future.

SOLICITING DEALER WARRANTS

     The Company has agreed to issue and sell, and the Dealer Manager has agreed
to purchase for the price of $.0008 per warrant, warrants (the "Soliciting
Dealer Warrants") to purchase one Share per Soliciting Dealer Warrant for each
Share sold by the Dealer Manager (and/or the Soliciting Dealers), up to a
maximum of 600,000 Soliciting Dealer Warrants.  The Soliciting Dealer Warrants
will be issued on a quarterly basis commencing 60 days after the date on which
the Shares are first sold pursuant to this Offering.  The Dealer Manager may
retain or reallow all Soliciting Dealer Warrants to the Soliciting Dealers
(except Soliciting Dealers in Minnesota), unless such issuance of the Soliciting
Dealer Warrants is prohibited by either federal or state securities laws.  The
Shares issuable upon exercise of the Soliciting Dealer Warrants are being
registered as part of this Offering.

     Each Soliciting Dealer will receive from the Dealer Manager one Soliciting
Dealer Warrant for each 25 Shares sold by such Soliciting Dealer during this
Offering.  All Shares sold by the Company other than through the Reinvestment
Plan will be included in the computation of the number of Shares sold to
determine the number of Soliciting Dealer Warrants to be issued.  The holder of
a Soliciting Dealer Warrant will be entitled to purchase one Share from the
Company at a price of $12 (120% of the public offering price per Share) during
the time period beginning one year from the effective date of this Offering and
ending five years after the effective date of this Offering (the "Exercise
Period").  A Soliciting Dealer Warrant may not be exercised unless the Shares to
be issued upon the exercise of the Soliciting Dealer Warrant have been
registered or are exempt from registration in the state of residence of the
holder of the Soliciting Dealer Warrant or if a prospectus required under the
laws of such state cannot be delivered to the buyer on behalf of the Company.
Notwithstanding the foregoing, no Soliciting Dealer Warrants will be exercisable
until one year from the effective date of the Offering.  In addition, holders of
Soliciting Dealer Warrants may not exercise the Soliciting Dealer Warrants to
the extent such exercise would jeopardize the Company's status as a REIT under
the Code.

     The terms of the Soliciting Dealer Warrants, including the exercise price
and the number and type of securities issuable upon exercise of a Soliciting
Dealer Warrant and the number of such warrants may be adjusted in the event of
stock dividends, stock splits, or a merger, consolidation, reclassification,
reorganization, recapitalization, or sale of assets.  Soliciting Dealer Warrants
are not transferable or assignable except by the Dealer Manager, the Soliciting
Dealers, their successors in interest, or to individuals who are officers of
such a person.  Exercise of these Soliciting Dealer Warrants will be under the
terms and conditions detailed in this Prospectus and in the Warrant Purchase
Agreement, which is an exhibit to the Registration Statement.

     Holders of Soliciting Dealer Warrants do not have the rights of
stockholders, may not vote on Company matters and are not entitled to receive
distributions until such time as such warrants are exercised.

ARTICLES OF INCORPORATION AND BYLAW PROVISIONS

  Restrictions on Ownership and Transfer

     For the Company to qualify as a REIT under the Code, it must meet certain
requirements concerning the ownership of its outstanding shares of capital
stock.  Specifically, not more than 50% in value of the Company's outstanding
shares of capital stock may be owned, directly or indirectly, by five or fewer
individuals (as defined in the Code to include certain entities) during the last
half of a taxable year, and the Company must be beneficially owned by

                                       47
<PAGE>
 
100 or more persons during at least 335 days of a taxable year of 12 months or
during a proportionate part of a shorter taxable year. See "Federal Income Tax
Considerations -- Requirements for Qualification." In addition, the Company must
meet certain requirements regarding the nature of its gross income in order to
qualify as a REIT. One such requirement is that at least 75% of the Company's
gross income for each year must consist of "rents from real property" and income
from certain other real property investments. No rent that the Company receives
from a tenant in which it owns 10% or more of the ownership interests will
qualify as "rents from real property." See "Federal Income Tax Considerations --
Requirements for Qualification -- Income Tests."

     Because the Board of Directors believes it is essential for the Company to
continue to qualify as a REIT, the Articles of Incorporation, subject to certain
exceptions described below, provide that no person may own, or be deemed to own
by virtue of the attribution provisions of the Code, more than 9.8% (the
"Ownership Limitation") of the number of outstanding shares of Common Stock or
more than 9.8% of the number of outstanding shares of any class of Preferred
Stock.

     Any transfer of Shares that would (i) result in any person owning, directly
or indirectly, Shares in excess of the Ownership Limitation, (ii) result in
Shares being owned by fewer than 100 persons (determined without reference to
any rules of attribution), (iii) result in the Company being "closely held"
within the meaning of section 856(h) of the Code, or (iv) cause the Company to
own, actually or constructively, 10% or more of the ownership interests in a
tenant of the Company's or the Operating Partnership's real property, within the
meaning of section 856(d)(2)(B) of the Code, will be null and void, and the
intended transferee will acquire no rights in such Shares.

     Subject to certain exceptions described below, any purported transfer of
Shares that would (i) result in any person owning, directly or indirectly,
Shares in excess of the Ownership Limitation, (ii) result in the Shares being
owned by fewer than 100 persons (determined without reference to any rules of
attribution), (iii) result in the Company being "closely held" within the
meaning of section 856(h) of the Code, or (iv) cause the Company to own,
actually or constructively, 10% or more of the ownership interests in a tenant
of the Company's or the Operating Partnership's real property, within the
meaning of section 856(d)(2)(B) of the Code, will be designated as "Shares-in-
Trust" and will be transferred automatically to a trust (a "Trust"), effective
on the day before the purported transfer of such Shares.  The record holder of
the Shares that are designated as Shares-in-Trust (the "Prohibited Owner") will
be required to submit such number of Shares to the Company for registration in
the name of the trustee of the Trust (the "Trustee").  The Trustee will be
designated by the Company, but will not be affiliated with the Company.  The
beneficiary of a Trust (the "Beneficiary") will be one or more charitable
organizations named by the Company.

     Shares-in-Trust will remain issued and outstanding Shares and will be
entitled to the same rights and privileges as all other shares of the same class
or series.  The Trustee will receive all dividends and distributions on the
Shares-in-Trust and will hold such dividends or distributions in trust for the
benefit of the Beneficiary.  The Trustee will vote all Shares-in-Trust.  The
Trustee will designate a permitted transferee of the Shares-in-Trust, provided
that the permitted transferee (i) purchases such Shares-in-Trust for valuable
consideration and (ii) acquires such Shares-in-Trust without such acquisition
resulting in another transfer to another Trust.

     The Prohibited Owner with respect to Shares-in-Trust will be required to
repay to the Trustee the amount of any dividends or distributions received by
the Prohibited Owner (i) that are attributable to any Shares-in-Trust and (ii)
the record date of which was on or after the date that such shares became
Shares-in-Trust.  Within 20 days of receiving notice from the Company that
shares of the Company's common stock have been transferred to the Trust, the
Company shall, at its sole option, either (i) repurchase such Shares-in-Trust
from the Prohibited Owner, or (ii) cause the Trustee to sell the Shares-in-Trust
on behalf of the Prohibited Owner to a third party (the "Option").  The
Prohibited Owner shall receive from the Trustee the lesser of (i) the price per
share in the transaction that created such Shares-in-Trust (or, in the case of a
gift or devise, the Market Price (as defined below) per share on the date of
such transfer) or (ii) the Market Price per share on the date that the Company,
or its designee, accepts such offer.  Any amounts received by the Trustee in
excess of the amounts to be paid to the Prohibited Owner will be distributed to
the Beneficiary.  Such purchase price amount shall be sent to the Prohibited
Owner within five business days from the close of such sale transaction.

     In connection with the Option described above, the Shares-in-Trust will be
deemed to have been offered for sale to the Company, or its designee.  The
Company will have the right to accept such offer for a period of 20 days after

                                       48
<PAGE>
 
the later of (i) the date of the purported transfer which resulted in such
Shares-in-Trust or (ii) the date the Company determines in good faith that a
transfer resulting in such Shares-in-Trust occurred.

     "Market Price" on any date shall mean the average of the Closing Price for
the five consecutive Trading Days ending on such date.  The "Closing Price" on
any date shall mean the last sale price, regular way, or, in case no such sale
takes place on such day, the average of the closing bid and asked prices,
regular way, in either case as reported in the principal consolidated
transaction reporting system with respect to securities listed or admitted to
trading on the NYSE or, if the Shares are not listed or admitted to trading on
the NYSE, as reported in the principal consolidated transaction reporting system
with respect to securities listed on the principal national securities exchange
on which the Shares are listed or admitted to trading or, if the Shares are not
listed or admitted to trading on any national securities exchange, the last
quoted price, or if not so quoted, the average of the high bid and low asked
prices in the over-the-counter market, as reported by the National Association
of Securities Dealers, Inc. Automated Quotation System or, if such system is no
longer in use, the principal other automated quotations system that may then be
in use or, if the Shares are not quoted by any such organization, the average of
the closing bid and asked prices as furnished by a professional market maker
making a market in the Shares selected by the Board of Directors, or, if no such
market maker exists, as determined in good faith by the Board of Directors.
"Trading Day" shall mean a day on which the principal national securities
exchange on which the Shares are listed or admitted to trading is open for the
transaction of business or, if the Shares are not listed or admitted to trading
on any national securities exchange, shall mean any day other than a Saturday, a
Sunday or a day on which banking institutions in the State of New York are
authorized or obligated by law or executive order to close.

     Any person who (a) acquires Shares in violation of the foregoing
restrictions or who owned Shares that were transferred to a Trust is required to
give immediately written notice to the Company of such event, and (b) transfers
or receives (or attempts to transfer or receive) Shares subject to such
limitations is required to give the Company at least 15 days written notice
prior to such transaction, and in both cases such persons shall provide to the
Company such other information as the Company may request in order to determine
the effect, if any, of such transfer on the Company's status as a REIT.

     All persons who own, directly or indirectly, more than 5% (or such lower
percentages as required pursuant to regulations under the Code) of the
outstanding Shares must, within 30 days after January 1 of each year, provide to
the Company a written statement or affidavit stating (i) the name and address of
such direct or indirect owner, (ii) the number of Shares owned directly or
indirectly, and (iii) a description of how such shares are held.  In addition,
each direct or indirect shareholder shall provide to the Company such additional
information as the Company may request in order to determine the effect, if any,
of such ownership on the Company's status as a REIT and to ensure compliance
with the Ownership Limitation.

     The Ownership Limitation generally will not apply to the acquisition of
Shares by an underwriter that participates in a public offering of such shares.
In addition, the Board of Directors, upon receipt of a ruling from the Service
or an opinion of counsel and upon such other conditions as the Board of
Directors may direct, may exempt a person from the Ownership Limitation under
certain circumstances.  The foregoing restrictions will continue to apply until
(i) the Board of Directors determines that it is no longer in the best interests
of the Company to attempt to qualify, or to continue to qualify, as a REIT and
(ii) there is an affirmative vote of a majority of the number of Shares entitled
to vote on such matter at a regular or special meeting of the shareholders of
the Company.

     All certificates representing Shares will bear a legend referring to the
restrictions described above.

     The Ownership Limitation could have the effect of discouraging a takeover
or other transaction in which holders of some, or a majority, of the Shares
might receive a premium from their Shares over the then prevailing market price
or which such holders might believe to be otherwise in their best interest.

  Number of Directors; Removal; Filling Vacancies

     The Articles of Incorporation and Bylaws provide that the number of
directors will consist of not less than 3 nor more than 15 persons, subject to
increase or decrease by the affirmative vote of 80% of the members of the entire

                                       49
<PAGE>
 
Board of Directors.  At all times a majority of the directors shall be
Independent Directors, except that upon the death, removal or resignation of an
Independent Director, such requirement shall not be applicable for 90 days.
Upon completion of the Offering, there will be five directors, three of whom
shall be Independent Directors.  The shareholders shall be entitled to vote on
the election or removal of directors, with each share entitled to one vote.  The
Articles of Incorporation provide that, subject to any rights of holders of any
class of preferred stock, and unless the Board of Directors otherwise
determines, any vacancies will be filled by the affirmative vote of a majority
of the remaining directors, though less than a quorum, provided that Independent
Directors shall nominate and approve directors to fill vacancies created by
Independent Directors.  Accordingly, the Board of Directors could temporarily
prevent any shareholder from enlarging the Board of Directors and filling the
new directorships with such shareholder's own nominees.  Any directors so
elected shall hold office until the next annual meeting of shareholders.

     A director may be removed with or without cause by the vote of the holders
of a majority of the outstanding shares of capital stock entitled to vote for
the election of directors at a special meeting of the shareholders called for
the purpose of removing such director.

LIMITATION OF LIABILITY AND INDEMNIFICATION

     The MGCL permits a Maryland corporation to include in its Articles of
Incorporation a provision limiting the liability of its directors and officers
to the corporation and its stockholders for money damages except for liability
resulting from (a) actual receipt of an improper benefit or profit in money,
property or services or (b) active and deliberate dishonesty established by a
final judgment as being material to the cause of action.

     Subject to the conditions set forth below, the Articles of Incorporation
provides that the Company shall indemnify and hold harmless a Director, Advisor
or Affiliate against any or all losses or liabilities reasonably incurred by
such Director, Advisor or Affiliate in connection with or by reason of any act
or omission performed or omitted to be performed on behalf of the Company in
such capacity.

     Under the Company's Articles of Incorporation, the Company shall not
indemnify its Directors, Advisor or any Affiliate for any liability or loss
suffered by the Directors, Advisors or Affiliates, nor shall it provide that the
Directors, Advisors or Affiliates be held harmless for any loss or liability
suffered by the Company, unless all of the following conditions are met: (i) the
Directors, Advisor or Affiliates have determined, in good faith, that the course
of conduct which caused the loss or liability was in the best interests of the
Company; (ii) the Directors, Advisor or Affiliates were acting on behalf of or
performing services of the Company; (iii) such liability or loss was not the
result of (A) negligence or misconduct by the Directors, excluding the
Independent Directors, Advisors or Affiliates; or (B) gross negligence or
willful misconduct by the Independent Directors; (iv) such indemnification or
agreement to hold harmless is recoverable only out of the Company's net assets
and not from Shareholders.  Notwithstanding the foregoing, the Directors,
Advisors or Affiliates and any persons acting as a broker-dealer shall not be
indemnified by the Company for any losses, liability or expenses arising from or
out of an alleged violation of federal or state securities laws by such party
unless one or more of the following conditions are met: (i) there has been a
successful adjudication on the merits of each count involving alleged securities
law violations as to the particular indemnitee; (ii) such claims have been
dismissed with prejudice on the merits by a court of competent jurisdiction as
to the particular indemnitee; (iii) a court of competent jurisdiction approves a
settlement of the claims against a particular indemnitee and finds that
indemnification of the settlement and the related costs should be made, and the
court considering the request for indemnification has been advised of the
position of the SEC and of the published position of any state securities
regulatory authority in which securities of the Company were offered or sold as
to indemnification for violations of securities laws.

     The Articles of Incorporation provides that the advancement of Company
funds to the Directors, Advisors or Affiliates for legal expenses and other
costs incurred as a result of any legal action for which indemnification is
being sought is permissible only if all of the following conditions are
satisfied: (i) the legal action relates to acts or omissions with respect to the
performance of duties or services on behalf of the Company; (ii) the legal
action is initiated by a third party who is not a Shareholder or the legal
action is initiated by a Shareholder acting in his or her capacity as such and a
court of competent jurisdiction specifically approves such advancement; (iii)
the Directors, Advisor or Affiliates undertake to repay the advanced funds to
the Company together with the applicable legal rate of interest thereon, in
cases in which such Directors, Advisor or Affiliates are found not to be
entitled to indemnification.

                                       50
<PAGE>
 
     The MGCL requires a Maryland corporation (unless its Articles of
Incorporation provide otherwise, which the Company's Articles of Incorporation
do not) to indemnify a director or officer who has been successful, on the
merits or otherwise, in the defense of any proceeding to which he is made a
party by reason of his service in that capacity.  The MGCL permits a Maryland
corporation to indemnify its present and former directors and officers, among
others, against judgments, penalties, fines, settlements and reasonable expenses
actually incurred by them in connection with any proceeding to which they may be
made a party by reason of their service in those or other capacities unless it
is established that (a) the act or omission of the director or officer was
material to the matter giving rise to the proceeding and (i) was committed in
bad faith or (ii) was the result of active and deliberate dishonesty, (b) the
director or officer actually received an improper personal benefit in money,
property or services or (c) in the case of any criminal proceeding, the director
or officer had reasonable cause to believe that the act or omission was
unlawful.  However, under the MGCL a Maryland corporation may not indemnify for
an adverse judgment in a suit by or in the right of the corporation or for a
judgment of liability on the basis that personal benefit was improperly
received, unless in either case a court orders indemnification and then only for
expenses.  In addition, the MGCL permits a corporation to advance reasonable
expenses to a director or officer upon the corporation's receipt of (a) a
written affirmation by the director or officer of his good faith belief that he
has met the standard of conduct necessary for indemnification by the Company as
authorized by the Bylaws and (b) a written undertaking by or on his behalf to
repay the amount paid or reimbursed by the Company if it shall ultimately be
determined that the standard of conduct was not met.  Indemnification under the
provisions of the MGCL is not deemed exclusive of any other rights, by
indemnification or otherwise, to which an officer or director may be entitled
under the Company's Articles of Incorporation or Bylaws, or under resolutions of
stockholders or directors, contract or otherwise.  It is the position of the
Commission that indemnification of directors an officers for liabilities arising
under the Securities Act is against public policy and is unenforceable pursuant
to Section 14 of the Securities Act.

     The Company intends to purchased and maintain insurance on behalf of all of
its directors and executive officers against liability asserted against or
incurred by them in their official capacities with the Company, whether or not
the Company is required or has the power to indemnify them against the same
liability.

     Causes of action resulting from violations of federal or state securities
law shall be governed by such law.

BUSINESS COMBINATIONS

     Under the MGCL, certain "business combinations" (including a merger,
consolidation, share exchange or, in certain circumstances, an asset transfer or
issuance or reclassification of equity securities) between a Maryland
corporation and any person who beneficially owns 10% or more of the voting power
of such corporation's shares or an affiliate of such corporation who, at any
time within the two-year period prior to the date in question, was the
beneficial owner of 10% or more of the voting power of the then-outstanding
voting shares of such corporation (an "Interested Stockholder") or an affiliate
thereof, are prohibited for five years after the most recent date on which the
Interested Stockholder became an Interested Stockholder.  Thereafter, any such
business combination must be recommended by the board of directors of such
corporation and approved by the affirmative vote of at least (a) 80% of the
votes entitled to be cast by holders of outstanding shares of voting stock of
the corporation and (b) two-thirds of the votes entitled to be cast by holders
of voting shares of such corporation other than shares held by the Interested
Stockholder with whom (or with whose affiliate) the business combination is to
be effected, unless, among other conditions, the corporation's common
stockholders receive a minimum price (as defined in the MGCL) for their shares
and the consideration is received in cash or in the same form as previously paid
by the Interested Stockholder for its shares.  These provisions of the MGCL do
not apply, however, to business combinations that are approved or exempted by
the board of directors of the corporation prior to the time that the Interested
Stockholder becomes an Interested Stockholder.

CONTROL SHARE ACQUISITION STATUTE

     The MGCL provides that "control shares" of a Maryland corporation acquired
in a "control share acquisition" have no voting rights except to the extent
approved by a vote of two-thirds of the votes entitled to be cast on the matter,
excluding shares owned by the acquiror, by officers or by directors who are
employees of the corporation.  "Control Shares" are voting shares which, if
aggregated with all other such shares previously acquired by the acquiror, or in
respect of which the acquiror is able to exercise or direct the exercise of
voting power (except solely by virtue of a revocable proxy), would entitle the
acquiror to exercise voting power in electing directors within one of the
following

                                       51
<PAGE>
 
ranges of voting power: (i) one-fifth or more but less than one-third, (ii) one-
third or more but less than a majority, or (iii) a majority or more of all
voting power. Control Shares do not include shares the acquiring person is then
entitled to vote as a result of having previously obtained stockholder approval.
A "control share acquisition" means the acquisition of control shares, subject
to certain exceptions.

     A person who has made or proposes to make a control share acquisition, upon
satisfaction of certain conditions (including an undertaking to pay expenses),
may compel the board of directors of the corporation to call a special meeting
of stockholders to be held within 50 days of demand to consider the voting
rights of the shares.  If no request for a meeting is made, the corporation may
itself present the question at any stockholders meeting.

     If voting rights are not approved at the meeting or if the acquiring person
does not deliver an acquiring person statement as required by the statute, then
subject to certain conditions and limitations, the corporation may redeem any or
all of the control shares (except those for which voting rights have previously
been approved) for fair value determined, without regard to the absence of
voting rights for the control shares, as of the date of the last control share
acquisition by the acquiror or of any meeting of stockholders at which the
voting rights of such shares are considered and not approved. If voting rights
for control shares are approved at a stockholders meeting and the acquiror
becomes entitled to vote a majority of the shares entitled to vote, all other
stockholders may exercise appraisal rights.  The fair value of the shares as
determined for purposes of such appraisal rights may not be less than the
highest price per share paid by the acquiror in the control share acquisition.

     The control share acquisition statute does not apply to shares acquired in
a merger, consolidation or share exchange, if the corporation is a party to the
transaction, or to acquisitions approved or exempted by the Articles of
Incorporation or bylaws of the corporation.

     The Articles of Incorporation and Bylaws of the Company contain a provision
exempting from the control share acquisition statute any and all acquisitions by
any person of the Company's capital stock.  There can be no assurance that such
provision will not be amended or eliminated at any time in the future.

AMENDMENT TO THE ARTICLES OF INCORPORATION

     The Articles of Incorporation of the Company may be amended by the
affirmative vote by holders of a majority of the shares then outstanding and
entitled to vote thereon, without the concurrence of the Board of Directors,
provided, however, (i)  no amendment may be made which would change any rights
with respect to any outstanding class of securities by reducing the amount
payable thereon upon liquidation or by diminishing or eliminating any voting
rights pertaining thereto; (ii) the provisions pertaining to amending the
Articles of Incorporation and reorganizations shall not be amended, (iii) no
term or provision of the Articles of Incorporation may be added, amended or
repealed in any respect that would, in the determination of the Board of
Directors, cause the Company not to qualify as a REIT under the Code, (iv)
certain provisions of the Articles of Incorporation, including provisions
relating to the removal of directors, Independent Directors, preemptive rights
of holders of stock and the indemnification and limitation of liability of
officers and directors may not be amended or repealed and (v) provisions
imposing cumulative voting in the election of directors may not be added to the
Articles of Incorporation, unless, in each such case, such action is approved by
the affirmative vote of the holders of not less than a majority of all the votes
entitled to be cast thereon.  The Board of Directors may amend the Articles of
Incorporation (without the concurrence by the stockholders) only to enable the
Company to qualify as a real estate investment trust under the Code.

DISSOLUTION OF THE COMPANY

     The dissolution of the Company must be approved by the affirmative vote of
the holders of not less than a majority of all of the votes entitled to be cast
on the matter.  Under the Articles of Incorporation, the Company will
automatically terminate and dissolve on January 30, 2008 (ten years after the
initial date of this Prospectus), unless the Listing occurs, in which event the
Company will automatically become a perpetual life entity.

ADVANCE NOTICE OF DIRECTOR NOMINATIONS AND NEW BUSINESS

     The Bylaws of the Company provide that (a) with respect to an annual
meeting of stockholders, nominations of persons for election to the Board of
Directors and the proposal of business to be considered by stockholders may be
made only (i) pursuant to the Company's notice of the meeting, (ii) by or at the
direction of the Board of Directors or (iii) by a stockholder who is entitled to
vote at the meeting and has complied with the advance notice procedures set
forth in the Bylaws and (b) with respect to special meetings of stockholders,
only the business specified in the Company's notice of meeting may be brought
before the meeting of stockholders and nominations of persons for election to
the Board of Directors may be made only (i) pursuant to the Company's notice of
the meeting, (ii) by or at the direction of the Board of Directors or (iii)
provided that the Board of Directors has determined that directors shall be
elected at such meeting, by a stockholder who is entitled to vote at the meeting
and has complied with the advance notice provisions set forth in the Bylaws.

MEETING OF STOCKHOLDERS

     The Company's Bylaws provide that annual meetings of stockholders shall be
held on a date and at the time set by the Board of Directors.  The Board of
Directors (including the Independent Directors) will take reasonable steps to
ensure that the annual stockholders meeting shall be set within a reasonable
period (not less than 30 days) following delivery of the annual report.  Special
meetings of the stockholders may be called by (i) the President of the Company,
(ii) the Chief Executive Officer or (iii) the Board of Directors.  As permitted
by the MGCL, the Bylaws of the Company provide that special meetings must be
called by the Secretary of the Company upon the written request of the holders
of shares entitled to cast not less than a majority of all votes entitled to be
cast at the meeting.

OPERATIONS

     The Articles of Incorporation require the Board of Directors generally to
use its best efforts to cause the Company to qualify as a REIT.  Although the
Company has opted to not be governed by Maryland's business combination and
control share acquisition statutes, if the Company's Articles of Incorporation
and Bylaws are amended to include them, such provisions of the MGCL could delay,
defer or prevent a transaction or a change in control of the Company that might
involve a premium price for holders of Shares or otherwise be in their best
interests.

INSPECTION OF BOOKS AND RECORDS

     The Advisor will keep, or cause to be kept, on behalf of the Company, full
and true books of account on an accrual basis of accounting, in accordance with
generally accepted accounting principles.  All of such books of account,
together with all other records of the Company, including a copy of the Articles
of Incorporation and any amendments thereto, will at all times be maintained at
the principal office of the Company, and will be open to inspection,
examination, and, for a reasonable charge, duplication upon reasonable notice
and during normal business hours by a stockholder or his agent.

     As a part of its books and records, the Company will maintain at its
principal office an alphabetical list of names of stockholders, along with their
addresses and telephone numbers and the number of Shares held by each
stockholder.  Such list shall be updated at least quarterly and shall be
available for inspection at the Company's home office by a stockholder or his or
her designated agent upon such stockholder's request.  Such list also shall be
mailed to any stockholder requesting the list within 10 days of a request.  The
Company may require the stockholder requesting the stockholder list to represent
that the list is not requested for a commercial purpose unrelated to the
stockholder's interest in the Company and that he or she will not make any
commercial distribution of such list or the information disclosed through such
inspection.  The Company may impose a reasonable charge for expenses incurred in
reproducing such list.  The list may not be sold or used for commercial
purposes.

RESTRICTIONS ON "ROLL-UP" TRANSACTIONS

     In connection with a proposed "Roll-Up Transaction," which, in general
terms, is any transaction involving the acquisition, merger, conversion, or
consolidation, directly or indirectly, of the Company and the issuance of
securities of 

                                       53
<PAGE>
 
an entity that would be created or would survive after the
successful completion of the Roll-Up Transaction (a "Roll-Up Entity"), an
appraisal of all of the Company's properties shall be obtained from an
independent appraiser.  In order to qualify as an independent appraiser for this
purpose(s), the person or entity shall have no material current or prior
business or personal relationship with the Advisor or Directors and shall be
engaged to a substantial extent in the business of rendering opinions regarding
the value of assets of the type held by the Company.  The Company's properties
shall be appraised on a consistent basis, and the appraisal shall be based on
the evaluation of all relevant information and shall indicate the value of the
Company's properties as of a date immediately prior to the announcement of the
proposed Roll-Up Transaction.  The appraisal shall assume an orderly liquidation
of properties over a 12-month period.  The terms of the engagement of such
Independent Expert shall clearly state that the engagement is for the benefit of
the Company and the stockholders.  A summary of the independent appraisal,
indicating all material assumptions underlying the appraisal, shall be included
in a report to stockholders in connection with a proposed Roll-Up Transaction.
In connection with a proposed Roll-Up Transaction, the person sponsoring the
Roll-Up Transaction shall offer to stockholders who vote against the proposal
the choice of:

     (i)  accepting the securities of the Roll-Up Entity offered in the proposed
          Roll-Up Transaction; or

     (ii)  one of the following:

               a.  remaining stockholders of the Company and preserving their
     interests therein on the same terms and conditions as existed previously;
     or

               b.  receiving cash in an amount equal to the stockholder's pro
     rata share of the appraised value of the net assets of the Company.

     The Company is prohibited from participating in any proposed Roll-Up
Transaction:

     (i) which would result in the stockholders having democracy rights in the
Roll-Up Entity that are less than those provided in the Company's Articles of
Incorporation and described elsewhere in this Prospectus, including rights with
respect to the election and removal of Directors, annual reports, annual and
special meetings, amendment of the Articles of Incorporation, and dissolution of
the Company;

     (ii) which includes provisions that would operate as a material impediment
to, or frustration of, the accumulation of shares by any purchaser of the
securities of the Roll-Up Entity (except to the minimum extent necessary to
preserve the tax status of the Roll-Up Entity), or which would limit the ability
of an investor to exercise the voting rights of its securities of the Roll-Up
Entity on the basis of the number of shares held by that investor;

     (iii)  in which investor's rights to access of records of the Roll-Up
Entity will be less than those provided in the Company's Articles of
Incorporation and described in "Inspection of Books and Records," above; or

     (iv) in which any of the costs of the Roll-Up Transaction would be borne by
the Company if the Roll-Up Transaction is not approved by the stockholders.

                       FEDERAL INCOME TAX CONSIDERATIONS

     The following is a summary of material federal income tax considerations
that may be relevant to a prospective holder of Shares in the Company.  Hunton &
Williams has acted as counsel to the Company and has reviewed this summary and
is of the opinion that it fairly summarizes the federal income tax
considerations that will be material to a holder of Shares. The discussion
contained herein does not address all aspects of taxation that may be relevant
to particular shareholders in light of their personal investment or tax
circumstances, or to certain types of shareholders (including insurance
companies, tax-exempt organizations, financial institutions or broker-dealers,
foreign corporations, and persons who are not citizens or residents of the
United States) subject to special treatment under the federal income tax laws.

     The statements in this discussion and the opinion of Hunton & Williams are
based on current provisions of the Code, existing, temporary, and currently
proposed Treasury Regulations promulgated under the Code, the legislative
history of the Code, existing administrative rulings and practices of the
Service, and judicial decisions.  No assurance can be given that future
legislative, judicial, or administrative actions or decisions, which may be
retroactive in effect, will not affect the accuracy of any statements in this
Prospectus with respect to the transactions entered into or contemplated prior
to the effective date of such changes.

     EACH PROSPECTIVE PURCHASER IS ADVISED TO CONSULT HIS OWN TAX ADVISOR
REGARDING THE SPECIFIC TAX CONSEQUENCES TO HIM OF THE PURCHASE, OWNERSHIP, AND
SALE OF SHARES AND OF THE COMPANY'S ELECTION TO BE TAXED AS A REIT, INCLUDING
THE FEDERAL, STATE, LOCAL, FOREIGN, AND OTHER TAX CONSEQUENCES OF SUCH PURCHASE,
OWNERSHIP, SALE, AND ELECTION, AND OF POTENTIAL CHANGES IN APPLICABLE TAX LAWS.

TAXATION OF THE COMPANY

     The Company currently has in effect an election to be taxed as a pass-
through entity under Subchapter S of the Code, but intends to revoke its S
election on the day prior to the date on which the Offering commences.  The
Company plans to make an election to be taxed as a REIT under sections 856
through 860 of the Code, effective for its short taxable year beginning on the
day prior to the date on which the Offering commences and ending on December 31,
1998.  The Company believes that, commencing with such taxable year, it will be
organized and will operate in such a manner as to qualify for taxation as a REIT
under the Code, and the Company intends to continue to operate in such a manner,
but no assurance can be given that the Company will operate in a manner so as to
qualify or remain qualified as a REIT.

     The sections of the Code relating to qualification and operation as a REIT
are highly technical and complex.  The following discussion sets forth the
material aspects of the Code sections that govern the federal income tax
treatment of a REIT and its shareholders.  The discussion is qualified in its
entirety by the applicable Code provisions, Treasury Regulations promulgated
thereunder, and administrative and judicial interpretations thereof, all of
which are subject to change prospectively or retroactively.

     Hunton & Williams has acted as counsel to the Company in connection with
the Offering and the Company's election to be taxed as a REIT.  In the opinion
of Hunton & Williams, assuming that the elections and other procedural steps
described in this discussion of "Federal Income Tax Considerations" are
completed by the Company in a timely fashion,  the Company's organization and
proposed method of operation will enable it to qualify to be taxed as a REIT
under the Code commencing with the Company's short taxable year beginning the
day prior to the date on which the Offering commences and ending December 31,
1998, and for its future taxable years.  Investors should be aware, however,
that opinions of counsel are not binding upon the Service or any court.  It must
be emphasized that Hunton & Williams' opinion is based on various assumptions
and is conditioned upon certain representations made by the Company as to
factual matters, including representations regarding the nature of the Company's
properties and the future conduct of its business.  Such factual assumptions and
representations are described below in this discussion of "Federal Income Tax
Considerations" and are set out in the federal income tax opinion that has been
delivered by Hunton & Williams.  Moreover, such qualification and taxation as a
REIT depends upon the Company's ability to meet on a 

                                       55
<PAGE>
 
continuing basis, through actual annual operating results, distribution levels,
and share ownership, the various qualification tests imposed under the Code
discussed below. Hunton & Williams will not review the Company's compliance with
those tests on a continuing basis. Accordingly, no assurance can be given that
the actual results of the Company's operations for any particular taxable year
will satisfy such requirements. For a discussion of the tax consequences of
failure to qualify as a REIT, see "Failure to Qualify."

     If the Company qualifies for taxation as a REIT, it generally will not be
subject to federal corporate income tax on its net income that is distributed
currently to its shareholders.  That treatment substantially eliminates the
"double taxation" (i.e., taxation at both the corporate and shareholder levels)
that generally results from investment in a corporation.  However, the Company
will be subject to federal income tax in the following circumstances.  First,
the Company will be taxed at regular corporate rates on any undistributed REIT
taxable income, including undistributed net capital gains.  Second, under
certain circumstances, the Company may be subject to the "alternative minimum
tax" on its undistributed items of tax preference, if any.  Third, if the
Company has (i) net income from the sale or other disposition of "foreclosure
property" that is held primarily for sale to customers in the ordinary course of
business or (ii) other nonqualifying income from foreclosure property, it will
be subject to tax at the highest corporate rate on such income.  Fourth, if the
Company has net income from prohibited transactions (which are, in general,
certain sales or other dispositions of property (other than foreclosure
property) held primarily for sale to customers in the ordinary course of
business), such income will be subject to a 100% tax.  Fifth, if the Company
should fail to satisfy the 75% gross income test or the 95% gross income test
(as discussed below), and nonetheless has maintained its qualification as a REIT
because certain other requirements have been met, it will be subject to a 100%
tax on the net income attributable to the greater of the amount by which the
Company fails the 75% or 95% gross income test. Sixth, if the Company should
fail to distribute during each calendar year at least the sum of (i) 85% of its
REIT ordinary income for such year, (ii) 95% of its REIT capital gain net income
for such year, and (iii) any undistributed taxable income from prior periods,
the Company would be subject to a 4% excise tax on the excess of such required
distribution over the amounts actually distributed.  Seventh, the Company may
elect to retain and pay income tax on the net long-term capital gain it receives
in a taxable year.  Finally, if the Company acquires any asset from a C
corporation (i.e., a corporation generally subject to full corporate-level tax)
in a transaction in which the basis of the asset in the Company's hands is
determined by reference to the basis of the asset (or any other asset) in the
hands of the C corporation and the Company recognizes gain on the disposition of
such asset during the 10-year period beginning on the date on which such asset
was acquired by the Company, then to the extent of such asset's "built-in-gain"
(i.e., the excess of the fair market value of such asset at the time of
acquisition by the Company over the adjusted basis in such asset at such time),
such gain will be subject to tax at the highest regular corporate rate
applicable (as provided in Treasury Regulations that have not yet been
promulgated).  The results described above with respect to the recognition of
"built-in-gain" assume that the Company will make an election pursuant to IRS
Notice 88-19 if it were to make any such acquisition.

REQUIREMENTS FOR QUALIFICATION

     The Code defines a REIT as a corporation, trust, or association (i) that is
managed by one or more trustees or directors; (ii) the beneficial ownership of
which is evidenced by transferable shares, or by transferable certificates of
beneficial interest; (iii) that would be taxable as a domestic corporation, but
for sections 856 through 860 of the Code; (iv) that is neither a financial
institution nor an insurance company subject to certain provisions of the Code;
(v) the beneficial ownership of which is held by 100 or more persons; (vi) not
more than 50% in value of the outstanding shares of which is owned, directly or
indirectly, by five or fewer individuals (as defined in the Code to include
certain entities) during the last half of each taxable year (the "5/50 Rule");
(vii) that makes an election to be a REIT (or has made such election for a
previous taxable year) and satisfies all relevant filing and other
administrative requirements established by the Service that must be met in order
to elect and maintain REIT status; (viii) that uses a calendar year for federal
income tax purposes and complies with the recordkeeping requirements of the Code
and Treasury Regulations promulgated thereunder; and (ix) that meets certain
other tests, described below, regarding the nature of its income and assets.
The Code provides that conditions (i) to (iv), inclusive, must be met during the
entire taxable year and that condition (v) must be met during at least 335 days
of a taxable year of 12 months, or during a proportionate part of a taxable year
of less than 12 months.  Conditions (v) and (vi) will not apply until after the
first taxable year for which an election is made by the Company to be taxed as a
REIT.  For purposes of determining stock ownership under the 5/50 Rule, a
supplemental unemployment compensation benefits plan, a private foundation, or a
portion of a trust permanently set aside or used exclusively for charitable
purposes generally is considered an individual.  A trust that is a qualified
trust under Code section 401(a), however, generally is not considered an
individual and beneficiaries of such 

                                       56
<PAGE>
 
trust are treated as holding shares of a REIT in proportion to their actuarial
interests in such trust for purposes of the 5/50 Rule.

     The Company anticipates issuing sufficient Shares with sufficient diversity
of ownership pursuant to the Offering to allow it to satisfy requirements (v)
and (vi) after its 1998 taxable year.  In addition, the Company's Articles of
Incorporation provide for restrictions regarding transfer of Shares that are
intended to assist the Company in continuing to satisfy the share ownership
requirements described in clauses (v) and (vi) above.  Such transfer
restrictions are described in "Description of Capital Stock -- Articles of
Incorporation and Bylaw Provisions -- Restrictions on Ownership and Transfer."

     The Company currently does not have any corporate subsidiaries, but may
have corporate subsidiaries in the future.  Code section 856(i) provides that a
corporation that is a "qualified REIT subsidiary" will not be treated as a
separate corporation, and all assets, liabilities, and items of income,
deduction, and credit of a "qualified REIT subsidiary" will be treated as
assets, liabilities, and items of income, deduction, and credit of the REIT.  A
"qualified REIT subsidiary" is a corporation, all of the capital stock of which
is owned by the REIT.  Thus, in applying the requirements described herein, any
qualified REIT subsidiaries of the Company will be ignored and all assets,
liabilities, and items of income, deduction, and credit of such subsidiaries
will be treated as assets, liabilities, and items of income, deduction, and
credit of the Company.

     In the case of a REIT that is a partner in a partnership, Treasury
Regulations provide that the REIT will be deemed to own its proportionate share
of the assets of the partnership and will be deemed to be entitled to the gross
income of the partnership attributable to such share.  In addition, the assets
and gross income of the partnership will retain the same character in the hands
of the REIT for purposes of section 856 of the Code, including satisfying the
gross income and asset tests described below.  Thus, the Company's proportionate
share of the assets, liabilities and items of income of the Operating
Partnership will be treated as assets, liabilities and items of income of the
Company for purposes of applying the requirements described herein

  Income Tests

     In order for the Company to qualify and to maintain its qualification as a
REIT, two requirements relating to the Company's gross income must be satisfied
annually.  First, at least 75% of the Company's gross income (excluding gross
income from prohibited transactions) for each taxable year must consist of
defined types of income derived directly or indirectly from investments relating
to real property or mortgages on real property (including "rents from real
property" and, in certain circumstances, interest) or temporary investment
income.  Second, at least 95% of the Company's gross income (excluding gross
income from prohibited transactions) for each taxable year must be derived from
such real property or temporary investments, and from dividends, other types of
interest, and gain from the sale or disposition of stock or securities, or from
any combination of the foregoing.   The specific application of these tests to
the Company is discussed below.

     The rent received by the Company from its tenants ("Rent") will qualify as
"rents from real property" in satisfying the gross income requirements for a
REIT described above only if several conditions are met.  First, the amount of
rent must not be based, in whole or in part, on the income or profits of any
person.  However, an amount received or accrued generally will not be excluded
from the term "rents from real property" solely by reason of being based on a
fixed percentage or percentages of receipts or sales.  Second, the Code provides
that rents received from a tenant will not qualify as "rents from real property"
in satisfying the gross income tests if the Company, or a direct or indirect
owner of 10% or more of the Company, directly or constructively owns 10% or more
of such tenant (a "Related Party Tenant").  Third, if rent attributable to
personal property, leased in connection with a lease of real property, is
greater than 15% of the total rent received under the lease, then the portion of
rent attributable to such personal property will not qualify as "rents from real
property."  Finally, for the Rent to qualify as "rents from real property," the
Company generally must not operate or manage its properties or furnish or render
services to the tenants of such properties, other than through an "independent
contractor" who is adequately compensated and from whom the Company derives no
revenue.  The "independent contractor" requirement, however, does not apply to
the extent the services provided by the Company are "usually or customarily
rendered" in connection with the rental of space for occupancy only and are not
otherwise considered "rendered to the occupant."  In addition, The Company may
render a de minimus amount of 

                                       57
<PAGE>
 
noncustomary services to its tenants, or manage or operate property, as long as
the amount received with respect to the services or management does not exceed
1% of the Company's income from the property.

     The Company has represented that it will not charge Rent for any portion of
any property that is based, in whole or in part, on the income or profits of any
person to the extent that the receipt of such Rent would jeopardize the
Company's status as a REIT.  In addition, the Company has represented that, to
the extent that it receives Rent from a Related Party Tenant, such Rent will not
cause the Company to fail to satisfy either the 75% or 95% gross income test.
The Company also has represented that it will not allow the Rent attributable to
personal property leased in connection with any lease of real property to exceed
15% of the total Rent received under the lease, if the receipt of such Rent
would cause the Company to fail to satisfy either the 75% or 95% gross income
test.

     The Company may provide certain services to its tenants.  The Company
believes and has represented that all such services will be considered "usually
or customarily rendered" in connection with the rental of space for occupancy
only and will not otherwise be considered "rendered to the occupant," so that
the provision of such services will not jeopardize the qualification of the Rent
as "rents from real property."  In the case of any services that are not "usual
and customary" under the foregoing rules, the Company intends to employ
qualifying independent contractors to provide such services to the extent that
the provision of such services would cause the Company to fail to satisfy either
the 75% or 95% gross income test.

     If any portion of the Rent does not qualify as "rents from real property"
because the Rent attributable to personal property leased in connection with any
lease of real property exceeds 15% of the total Rent received under the lease
for a taxable year, the portion of the Rent that is attributable to personal
property will not be qualifying income for purposes of either the 75% or 95%
gross income test.  Thus, if the Rent attributable to personal property, plus
any other income received by the Company during a taxable year that is not
qualifying income for purposes of the 95% gross income test, exceeds 5% of the
Company's gross income during such year, the Company likely would lose its REIT
status.  If, however, any portion of the Rent received under a lease does not
qualify as "rents from real property" because either (i) the Rent is considered
based on the income or profits of any person or (ii) the tenant is a Related
Party Tenant, none of the Rent received by the Company under such lease would
qualify as "rents from real property."  In that case, if the Rent received by
the Company under such lease, plus any other income received by the Company
during the taxable year that is not qualifying income for purposes of the 95%
gross income test, exceeds 5% of the Company's gross income for such year, the
Company likely would lose its REIT status.  Finally, if any portion of the Rent
does not qualify as "rents from real property" because the Company furnishes
noncustomary services with respect to a property other than through a qualifying
independent contractor, and the amount received with respect to the services
exceeds 1% of the Company's income from the property, none of the Rent received
by the Company with respect to the related property would qualify as "rents from
real property."  In that case, if the Rent received by the Company with respect
to the related property, plus any other income received by the Company during
the taxable year that is not qualifying income for purposes of the 95% gross
income test, exceeds 5% of the Company's gross income for such year, the Company
would lose its REIT status.

     In addition to the Rent, the Company's tenants will be required to pay
additional charges, such as late fees (the "Additional Charges").  To the extent
that the Additional Charges represent either (i) reimbursements of amounts that
a tenant is obligated to pay to third parties or (ii) penalties for nonpayment
or late payment of such amounts, the Additional Charges should qualify as "rents
from real property."  To the extent that Additional Charges represent interest
that is accrued on the late payment of the Rent or Additional Charges, such
Additional Charges should be treated as interest that qualifies for the 95%
gross income test, but not the 75% gross income test.

     The term "interest" generally does not include any amount received or
accrued (directly or indirectly) if the determination of such amount depends in
whole or in part on the income or profits of any person.  However, an amount
received or accrued generally will not be excluded from the term "interest"
solely by reason of being based on a fixed percentage or percentages of receipts
or sales.  Furthermore, to the extent that interest from a loan that is based on
the residual cash proceeds from sale of the property securing the loan
constitutes a "shared appreciation provision" (as defined in the Code), income
attributable to such participation feature will be treated as gain from the sale
of the secured property.

                                       58
<PAGE>
 
     The net income derived from any prohibited transaction is subject to a 100%
tax.  The term "prohibited transaction" generally includes a sale or other
disposition (whether by the Company or the Operating Partnership) of property
(other than foreclosure property) that is held primarily for sale to customers
in the ordinary course of a trade or business.  The Company believes no asset
owned by the Company or the Operating Partnership will be held for sale to
customers and that a sale of any such asset will not be in the ordinary course
of business of the Company or the Operating Partnership.  Whether property is
held "primarily for sale to customers in the ordinary course of a trade or
business" depends, however, on the facts and circumstances in effect from time
to time, including those related to a particular property.  Nevertheless, the
Company will attempt to comply with the terms of safe-harbor provisions in the
Code prescribing when asset sales will not be characterized as prohibited
transactions.  Complete assurance cannot be given, however, that the Company can
comply with the safe-harbor provisions of the Code or avoid owning property that
may be characterized as property held "primarily for sale to customers in the
ordinary course of a trade or business."

     The Company will be subject to tax at the maximum corporate rate on any
income from foreclosure property (other than income that would be qualified
income under the 75% gross income test), less expenses directly connected with
the production of such income.  However, gross income from such foreclosure
property will be qualifying income under the 75% and 95% gross income tests.
"Foreclosure property" is defined as any real property (including interests in
real property) and any personal property incident to such real property (i) that
is acquired by a REIT as the result of such REIT having bid in such property at
foreclosure, or having otherwise reduced such property to ownership or
possession by agreement or process of law, after there was a default (or default
was imminent) on a lease of such property or on an indebtedness that such
property secured and (ii) for which such REIT makes a proper election to treat
such property as foreclosure property.  However, a REIT will not be considered
to have foreclosed on a property where such REIT takes control of the property
as a mortgagee-in-possession and cannot receive any profit or sustain any loss
except as a creditor of the mortgagor.  Under the Code, property generally
ceases to be foreclosure property with respect to a REIT on the date that is two
years after the date such REIT acquired such property (or longer if an extension
is granted by the Secretary of the Treasury).  The foregoing grace period is
terminated and foreclosure property ceases to be foreclosure property on the
first day (i) on which a lease is entered into with respect to such property
that, by its terms, will give rise to income that does not qualify under the 75%
gross income test or any amount is received or accrued, directly or indirectly,
pursuant to a lease entered into on or after such day that will give rise to
income that does not qualify under the 75% gross income test, (ii) on which any
construction takes place on such property (other than completion of a building,
or any other improvement, where more than 10% of the construction of such
building or other improvement was completed before default became imminent) or
(iii) which is more than 90 days after the day on which such property was
acquired by the REIT and the property is used in a trade or business that is
conducted by the REIT (other than through an independent contractor from whom
the REIT itself does not derive or receive any income).

     It is possible that, from time to time, the Company will enter into hedging
transactions with respect to one or more of its assets or liabilities.  Any such
hedging transactions could take a variety of forms, including interest rate swap
contracts, interest rate cap or floor contracts, futures or forward contracts,
and options.  To the extent that the Company enters into an interest rate swap
or cap contract, option, futures contract, forward rate agreement or similar
financial instrument to reduce its interest rate risk with respect to
indebtedness incurred or to be incurred to acquire or carry real estate assets,
any periodic income or gain from the disposition of such contract should be
qualifying income for purposes of the 95% gross income test, but not the 75%
gross income test.  To the extent that the Company hedges with other types of
financial instruments or in other situations, it may not be entirely clear how
the income from those transactions will be treated for purposes of the various
income tests that apply to REITs under the Code.  The Company intends to
structure any hedging transactions in a manner that does not jeopardize its
status as a REIT.

     If the Company fails to satisfy one or both of the 75% or 95% gross income
tests for any taxable year, it nevertheless may qualify as a REIT for such year
if it is entitled to relief under certain provisions of the Code.  Those relief
provisions generally will be available if the Company's failure to meet such
tests is due to reasonable cause and not due to willful neglect, the Company
attaches a schedule of the sources of its income to its return, and any
incorrect information on the schedule was not due to fraud with intent to evade
tax.  It is not possible, however, to state whether in all circumstances the
Company would be entitled to the benefit of those relief provisions.  As
discussed above in "Federal Income Tax Considerations -- Taxation of the
Company," even if those relief provisions apply, a 100% tax would be imposed on
the net income attributable to the greater of the amount by which the Company
fails the 75% or 95% gross income test.

  Asset Tests

     The Company, at the close of each quarter of each taxable year, also must
satisfy two tests relating to the nature of its assets. First, at least 75% of
the value of the Company's total assets must be represented by cash or cash
items (including certain receivables), government securities, "real estate
assets," or, in cases where the Company raises new capital through stock or
long-term (at least five-year) debt offerings, temporary investments in stock or
debt instruments during the one-year period following the Company's receipt of
such capital.  The term "real estate assets" includes interests in real
property, interests in mortgages on real property to the extent the principal
balance of a mortgage does not exceed the value of the associated real property,
and shares of other REITs. For purposes of the 75% asset test, the term
"interest in real property" includes an interest in land and improvements
thereon, such as buildings or other inherently permanent structures (including
items that are structural components of such buildings or structures), a
leasehold of real property, and an option to acquire real property (or a
leasehold of real property).  Second, of the investments not included in the 75%
asset class, the value of any one issuer's securities owned by the Company may
not exceed 5% of the value of the Company's total assets and the Company may not
own more than 10% of any one issuer's outstanding voting securities (except for
its interests in the Operating Partnership and any qualified REIT subsidiary).

     The Company has represented that (i) at least 75% of the value of its total
assets will be represented by real estate assets, cash and cash items (including
receivables), and government securities and (ii) it will not own (A) securities
of any one issuer the value of which exceeds 5% of the value of the Company's
total assets or (B) more than 10% of any one issuer's outstanding voting
securities (except for its interests in the Operating Partnership and any
qualified REIT subsidiary).  In addition, the Company has represented that it
will not acquire or dispose, or cause the Operating Partnership to acquire or
dispose, of assets in the future in a way that would cause it to violate either
asset test.

     If the Company should fail to satisfy the asset tests at the end of a
calendar quarter, such a failure would not cause it to lose its REIT status if
(i) it satisfied the asset tests at the close of the preceding calendar quarter
and (ii) the discrepancy between the value of the Company's assets and the asset
test requirements arose from changes in the market values of its assets and was
not wholly or partly caused by an acquisition of one or more nonqualifying
assets.  If the condition described in clause (ii) of the preceding sentence
were not satisfied, the Company still could avoid disqualification by
eliminating any discrepancy within 30 days after the close of the calendar
quarter in which it arose.

  Distribution Requirements

     The Company, in order to avoid corporate income taxation of the earnings it
distributes, is required to distribute with respect to each taxable year
dividends (other than capital gain dividends and retained earnings) to its
shareholders in an aggregate amount at least equal to (i) the sum of (A) 95% of
its "REIT taxable income" (computed without regard to the dividends paid
deduction and its net capital gain) and (B) 95% of the net income (after tax),
if any, from foreclosure property, minus (ii) the sum of certain items of
noncash income.  Such distributions must be paid in the taxable year to which
they relate, or in the following taxable year if declared before the Company
timely files its federal income tax return for such year and if paid on or
before the first regular dividend payment date after such declaration. To the
extent that the Company does not distribute all of its net capital gain or
distributes at least 95%, but less than 100%, of its "REIT taxable income," as
adjusted, it will be subject to tax thereon at regular ordinary and capital
gains corporate tax rates. Furthermore, if the Company should fail to distribute
during each calendar year at least the sum of (i) 85% of its REIT ordinary
income for such year, (ii) 95% of its REIT capital gain income for such year,
and (iii) any undistributed taxable income from prior periods, the Company would
be subject to a 4% nondeductible excise tax on the excess of such required
distribution over the amounts actually distributed.  The Company may elect to
retain and pay income on the net long-term capital gain it receives in a taxable
year.  Any such retained capital gain will be treated as if it had been
distributed to the Company's shareholders for purposes of the 4% excise tax.
The Company intends to make timely distributions sufficient to satisfy the
annual distribution requirements.

     It is possible that, from time to time, the Company may experience timing
differences between (i) the actual receipt of income and actual payment of
deductible expenses and (ii) the inclusion of that income and deduction of such
expenses in arriving at its REIT taxable income.  Further, it is possible that,
from time to time, the Company may be allocated a share of net capital gain
attributable to the sale of depreciated property that exceeds its allocable
share of cash attributable to that sale. Therefore, the Company may have less
cash than is necessary to meet its annual 95% 

                                       60
<PAGE>
 
distribution requirement or to avoid corporate income tax or the excise tax
imposed on certain undistributed income. In such a situation, the Company may
find it necessary to arrange for short-term (or possibly long-term) borrowings
or to raise funds through the issuance of additional Shares.

     Under certain circumstances, the Company may be able to rectify a failure
to meet the distribution requirements for a year by paying "deficiency
dividends" to its shareholders in a later year, which may be included in the
Company's deduction for dividends paid for the earlier year.  Although the
Company may be able to avoid being taxed on amounts distributed as deficiency
dividends, it will be required to pay to the Service interest based upon the
amount of any deduction taken for deficiency dividends.

  Recordkeeping Requirements

     Pursuant to applicable Treasury Regulations, in order to be able to elect
to be taxed as a REIT, the Company must maintain certain records.  In addition,
in order to avoid a monetary penalty, the Company must request, on an annual
basis, certain information from its shareholders designed to disclose the actual
ownership of its outstanding shares.  The Company intends to comply with such
requirements.

  Partnership Anti-Abuse Rule

     The U.S. Department of the Treasury has issued a final regulation (the
"Anti-Abuse Rule") under the partnership provisions of the Code (the
"Partnership Provisions") that authorizes the Service, in certain abusive
transactions involving partnerships, to disregard the form of the transaction
and recast it for federal tax purposes as the Service deems appropriate. The
Anti-Abuse Rule applies where a partnership is formed or utilized in connection
with a transaction (or series of related transactions) with a principal purpose
of substantially reducing the present value of the partners' aggregate federal
tax liability in a manner inconsistent with the intent of the Partnership
Provisions.  The Anti-Abuse Rule states that the Partnership Provisions are
intended to permit taxpayers to conduct joint business (including investment)
activities though a flexible arrangement that accurately reflects the partners'
economic agreement and clearly reflects the partners' income without incurring
any entity-level tax.  The purposes for structuring a transaction involving a
partnership are determined based on all of the facts and circumstances,
including a comparison of the purported business purpose for a transaction and
the claimed tax benefits resulting from the transaction.  A reduction in the
present value of the partners' aggregate federal tax liability through the use
of a partnership does not, by itself, establish inconsistency with the intent of
the Partnership Provisions.

     The Anti-Abuse Rule contains an example in which a corporation that elects
to be treated as a REIT contributes substantially all of the proceeds from a
public offering to a partnership in exchange for a general partnership interest.
The limited partners of the partnership contribute real property assets to the
partnership, subject to liabilities that exceed their respective aggregate bases
in such property.  In addition, some of the limited partners have the right,
beginning two years after the formation of the partnership, to require the
redemption of their limited partnership interests in exchange for cash or REIT
stock (at the REIT's option) equal to the fair market value of their respective
interests in the partnership at the time of the redemption.  The example
concludes that the use of the partnership is not inconsistent with the intent of
the Partnership Provisions and, thus, cannot be recast by the Service.  However,
the redemption rights associated with the OP Units will not conform in all
respects to the redemption rights contained in the foregoing example.  Moreover,
the Anti-Abuse Rule is extraordinarily broad in scope and is applied based on an
analysis of all of the facts and circumstances.  As a result, there can be no
assurance that the Service will not attempt to apply the Anti-Abuse Rule to the
Company.  If the conditions of the Anti-Abuse Rule are met, the Service is
authorized to take appropriate enforcement action, including disregarding the
Operating Partnership for federal tax purposes or treating one or more of the
partners as nonpartners.  Any such action potentially could jeopardize the
Company's status as a REIT.

FAILURE TO QUALIFY

     If the Company fails to qualify for taxation as a REIT in any taxable year,
and the relief provisions do not apply, the Company will be subject to tax
(including any applicable alternative minimum tax) on its taxable income at
regular corporate rates. Distributions to the Company's shareholders in any year
in which the Company fails to qualify will not be deductible by the Company nor
will they be required to be made.  In such event, to the extent of current and

                                       61
<PAGE>
 
accumulated earnings and profits, all distributions to shareholders will be
taxable as ordinary income and, subject to certain limitations of the Code,
corporate distributees may be eligible for the dividends received deduction.
Unless entitled to relief under specific statutory provisions, the Company also
will be disqualified from taxation as a REIT for the four taxable years
following the year during which the Company ceased to qualify as a REIT.  It is
not possible to state whether in all circumstances the Company would be entitled
to such statutory relief.

TAXATION OF TAXABLE U.S. SHAREHOLDERS

     As long as the Company qualifies as a REIT, distributions made to the
Company's taxable U.S. shareholders out of current or accumulated earnings and
profits (and not designated as capital gain dividends or retained capital gains)
will be taken into account by such U.S. shareholders as ordinary income and will
not be eligible for the dividends received deduction generally available to
corporations. As used herein, the term "U.S. shareholder" means a holder of
Shares that for U.S. federal income tax purposes is (i) a citizen or resident of
the U.S., (ii) a corporation, partnership, or other entity created or organized
in or under the laws of the U.S. or of any political subdivision thereof, or
(iii) an estate whose income from sources without the United States is
includible in gross income for U.S. federal income tax purposes regardless of
its connection with the conduct of a trade or business within the United States,
or (iv) any trust with respect to which (A) a U.S. court is able to exercise
primary supervision over the administration of such trust and (B) one or more
U.S. fiduciaries have the authority to control all substantial decisions of the
trust.

     Distributions that are designated as capital gain dividends will be taxed
as long-term capital gains (to the extent they do not exceed the Company's
actual net capital gain for the taxable year) without regard to the period for
which the shareholder has held his Shares.  However, corporate shareholders may
be required to treat up to 20% of certain capital gain dividends as ordinary
income.  The Company may elect to retain and pay income tax on the net long-term
capital gain if received in a taxable year.  In that case, the Company's
shareholders would include in income as long-term capital gain their
proportionate share of the Company's retained long-term capital gain.  In
addition, the shareholders would be deemed to have paid their proportionate
share of the tax paid by the Company, which amount would be credited or refunded
to the shareholders.  Each shareholder's basis in his Shares would be increased
by the amount of the undistributed long-term capital gain included in the
shareholder's income, less the shareholder's share of the tax paid by the
Company.

     Distributions in excess of current and accumulated earnings and profits
will not be taxable to a shareholder to the extent that they do not exceed the
adjusted basis of the shareholder's Shares, but rather will reduce the adjusted
basis of such Shares. To the extent that such distributions in excess of current
and accumulated earnings and profits exceed the adjusted basis of a
shareholder's Shares, such distributions will be included in income as long-term
capital gain (or short-term capital gain if the Shares have been held for one
year or less), assuming the Shares are capital assets in the hands of the
shareholder. In addition, any distribution declared by the Company in October,
November, or December of any year and payable to a shareholder of record on a
specified date in any such month shall be treated as both paid by the Company
and received by the shareholder on December 31 of such year, provided that the
distribution is actually paid by the Company during January of the following
calendar year.

     Shareholders may not include in their individual income tax returns any net
operating losses or capital losses of the Company. Instead, such losses would be
carried over by the Company for potential offset against its future income
(subject to certain limitations).  Taxable distributions from the Company and
gain from the disposition of the Shares will not be treated as passive activity
income and, therefore, shareholders generally will not be able to apply any
"passive activity losses" (such as losses from certain types of limited
partnerships in which a shareholder is a limited partner) against such income.
In addition, taxable distributions from the Company generally will be treated as
investment income for purposes of the investment interest limitations.  Capital
gains from the disposition of Shares (or distributions treated as such),
however, will be treated as investment income only if the shareholder so elects,
in which case such capital gains will be taxed at ordinary income rates.  The
Company will notify shareholders after the close of the Company's taxable year
as to the portions of the distributions attributable to that year that
constitute ordinary income, return of capital, and capital gain.

                                       62
<PAGE>
 
TAXATION OF SHAREHOLDERS ON THE DISPOSITION OF THE SHARES

     In general, any gain or loss realized upon a taxable disposition of Shares
by a shareholder who is not a dealer in securities will be treated as long-term
capital gain or loss if such Shares have been held for more than one year and
otherwise as short-term capital gain or loss.  However, any loss upon a sale or
exchange of Shares by a shareholder who has held such shares for six months or
less (after applying certain holding period rules), will be treated as a long-
term capital loss to the extent of distributions from the Company required to be
treated by such shareholder as long-term capital gain.  All or a portion of any
loss realized upon a taxable disposition of Shares may be disallowed if other
Shares are purchased within 30 days before or after the disposition.

CAPITAL GAINS AND LOSSES

     A capital asset generally must be held for more than one year in order for
gain or loss derived from its sale or exchange to be treated as long-term
capital gain or loss.  The highest marginal individual income tax rate is 39.6%.
The maximum tax rate on net capital gains applicable to noncorporate taxpayers
is 28% for sales and exchanges of assets held for more than one year, but not
more than 18 months, and 20% for sales and exchanges of assets held for more
than 18 months.  The maximum tax rate applicable to noncorporate taxpayers on
long-term capital gain from the sale of "Section 1250 property" (depreciable
real property) is 25% to the extent such gain would have been treated as
ordinary income if the property were "Section 1245 property."  With respect to
distributions designated by the Company as capital gain dividends and deemed
distributions of retained capital gains, the Company may designate (subject to
certain limits) whether such a distribution is taxable to shareholders at a 20%,
25% or 28% rate.  Thus, the tax rate differential between capital gain and
ordinary income for individuals may be significant.  In addition, the
characterization of income as capital or ordinary may affect the deductibility
of capital losses.  Capital losses not offset by capital gains may be deducted
against an individual's ordinary income only up to a maximum annual amount of
$3,000.  Unused capital losses may be carried forward.  All net capital gain of
a corporate taxpayer is subject to tax at ordinary corporate rates. A corporate
taxpayer can deduct capital losses only to the extent of capital gains, with
unused losses being carried back three years and forward five years.

INFORMATION REPORTING REQUIREMENTS AND BACKUP WITHHOLDING

     The Company will report to its U.S. shareholders and to the Service the
amount of distributions paid during each calendar year, and the amount of tax
withheld, if any.  Under the backup withholding rules, a shareholder may be
subject to backup withholding at the rate of 31% with respect to distributions
paid unless such holder (i) is a corporation or comes within certain other
exempt categories and, when required, demonstrates this fact or (ii) provides a
taxpayer identification number, certifies as to no loss of exemption from backup
withholding, and otherwise complies with the applicable requirements of the
backup withholding rules.  A shareholder who does not provide the Company with
his correct taxpayer identification number also may be subject to penalties
imposed by the Service.  Any amount paid as backup withholding will be
creditable against the shareholder's income tax liability.  In addition, the
Company may be required to withhold a portion of capital gain distributions to
any shareholders who fail to certify their nonforeign status to the Company.
The Service has issued final regulations regarding the backup withholding rules
as applied to Non-U.S. shareholders.  Those regulations would alter the current
system of backup withholding compliance and will be effective for distributions
made after December 31, 1998.  See "--Taxation of Non-U.S. shareholders."

TAXATION OF TAX-EXEMPT SHAREHOLDERS

     Tax-exempt entities, including qualified employee pension and profit
sharing trusts and individual retirement accounts ("Exempt Organizations"),
generally are exempt from federal income taxation. However, they are subject to
taxation on their unrelated business taxable income ("UBTI").  While many
investments in real estate generate UBTI, the Service has issued a published
ruling that dividend distributions from a REIT to an exempt employee pension
trust do not constitute UBTI, provided that the shares of the REIT are not
otherwise used in an unrelated trade or business of the exempt employee pension
trust.  Based on that ruling, amounts distributed by the Company to Exempt
Organizations generally should not constitute UBTI.  However, if an Exempt
Organization finances its acquisition of Shares with debt, a portion of its
income from the Company will constitute UBTI pursuant to the "debt-financed
property" rules.  Furthermore, social clubs, voluntary employee benefit
associations, supplemental unemployment benefit trusts, and qualified group
legal services plans that are exempt from taxation under paragraphs (7), (9),
(17), and (20), respectively, 

                                       63
<PAGE>
 
of Code section 501(c) are subject to different UBTI rules, which generally will
require them to characterize distributions from the Company as UBTI. In
addition, in certain circumstances, a pension trust that owns more than 10% of
the Company's shares is required to treat a percentage of the dividends from the
Company as UBTI (the "UBTI Percentage"). The UBTI Percentage is the gross income
derived by the Company from an unrelated trade or business (determined as if the
Company were a pension trust) divided by the gross income of the Company for the
year in which the dividends are paid. The UBTI rule applies to a pension trust
holding more than 10% of the Company's stock only if (i) the UBTI Percentage is
at least 5%, (ii) the Company qualifies as a REIT by reason of the modification
of the 5/50 Rule that allows the beneficiaries of the pension trust to be
treated as holding shares of the Company in proportion to their actuarial
interests in the pension trust, and (iii) either (A) one pension trust owns more
than 25% of the value of the Company's shares or (B) a group of pension trusts
individually holding more than 10% of the value of the Company's shares
collectively owns more than 50% of the value of the Company's shares. Because
the Ownership Limitation prohibits any shareholder from owning more than 9.8% of
the number of outstanding Shares or more than 9.8% of the number of outstanding
Shares of any class of preferred stock, no pension trust should hold more than
10% of the value of the Company's Shares.

TAXATION OF NON-U.S. SHAREHOLDERS

     The rules governing U.S. federal income taxation of nonresident alien
individuals, foreign corporations, foreign partnerships, and other foreign
shareholders (collectively, "Non-U.S. shareholders") are complex and no attempt
will be made herein to provide more than a summary of such rules.  PROSPECTIVE
NON-U.S. SHAREHOLDERS SHOULD CONSULT WITH THEIR OWN TAX ADVISORS TO DETERMINE
THE IMPACT OF FEDERAL, STATE, AND LOCAL INCOME TAX LAWS WITH REGARD TO AN
INVESTMENT IN THE SHARES, INCLUDING ANY REPORTING REQUIREMENTS.

     Distributions to Non-U.S. shareholders that are not attributable to gain
from sales or exchanges by the Company of U.S. real property interests and are
not designated by the Company as capital gains dividends or retained capital
gains will be treated as dividends of ordinary income to the extent that they
are made out of current or accumulated earnings and profits of the Company.
Such distributions ordinarily will be subject to a withholding tax equal to 30%
of the gross amount of the distribution unless an applicable tax treaty reduces
or eliminates that tax.  However, if income from the investment in the Shares is
treated as effectively connected with the Non-U.S. Shareholder's conduct of a
U.S. trade or business, the Non-U.S. Shareholder generally will be subject to
federal income tax at graduated rates, in the same manner as U.S. shareholders
are taxed with respect to such distributions (and also may be subject to the 30%
branch profits tax in the case of a Non-U.S. Shareholder that is a non-U.S.
corporation).  The Company expects to withhold U.S. income tax at the rate of
30% on the gross amount of any such distributions made to a Non-U.S. Shareholder
unless (i) a lower treaty rate applies and any required form evidencing
eligibility for that reduced rate is filed with the Company or (ii) the Non-U.S.
Shareholder files an IRS Form 4224 with the Company claiming that the
distribution is effectively connected income.  The Service has issued
regulations that modify the manner in which the Company complies with the
withholding requirements.  Those regulations are effective for distributions
made after December 31, 1998.  Distributions in excess of current and
accumulated earnings and profits of the Company will not be taxable to a
shareholder to the extent that such distributions do not exceed the adjusted
basis of the shareholder's Shares, but rather will reduce the adjusted basis of
such shares. To the extent that distributions in excess of current and
accumulated earnings and profits exceed the adjusted basis of a Non-U.S.
Shareholder's Shares, such distributions will give rise to tax liability if the
Non-U.S. Shareholder would otherwise be subject to tax on any gain from the sale
or disposition of his Shares, as described below.  Because it generally cannot
be determined at the time a distribution is made whether or not such
distribution will be in excess of current and accumulated earnings and profits,
the entire amount of any distribution normally will be subject to withholding at
the same rate as a dividend.  However, amounts so withheld are refundable to the
extent it is determined subsequently that such distribution was, in fact, in
excess of current and accumulated earnings and profits of the Company.

     The Company is required to withhold 10% of any distribution in excess of
its current and accumulated earnings and profits.  Consequently, although the
Company intends to withhold at a rate of 30% on the entire amount of any
distribution, to the extent that the Company does not do so, any portion of a
distribution not subject to withholding at a rate of 30% will be subject to
withholding at a rate of 10%.

                                       64
<PAGE>
 
     For any year in which the Company qualifies as a REIT, distributions that
are attributable to gain from sales or exchanges by the Company of U.S. real
property interests will be taxed to a Non-U.S. Shareholder under the provisions
of the Foreign Investment in Real Property Tax Act of 1980 ("FIRPTA").  Under
FIRPTA, distributions attributable to gain from sales of U.S. real property
interests are taxed to a Non-U.S. Shareholder as if such gain were effectively
connected with a U.S. business.  Non-U.S. shareholders thus would be taxed at
the normal capital gain rates applicable to U.S. shareholders (subject to
applicable alternative minimum tax and a special alternative minimum tax in the
case of nonresident alien individuals).  Distributions subject to FIRPTA also
may be subject to the 30% branch profits tax in the hands of a non-U.S.
corporate shareholder not entitled to treaty relief or exemption. The Company is
required to withhold 35% of any distribution that is or could be designated by
the Company as a capital gains dividend.  The amount withheld is creditable
against the Non-U.S. Shareholder's FIRPTA tax liability.

     Gain recognized by a Non-U.S. Shareholder upon a sale of his Shares
generally will not be taxed under FIRPTA if the Company is a "domestically
controlled REIT," defined generally as a REIT in which at all times during a
specified testing period less than 50% in value of the stock was held directly
or indirectly by non-U.S. persons.  However, no assurance can be given that the
Company will be a "domestically controlled REIT." Furthermore, gain not subject
to FIRPTA will be taxable to a Non-U.S. Shareholder if (i) investment in Shares
is effectively connected with the Non-U.S. Shareholder's U.S. trade or business,
in which case the Non-U.S. Shareholder will be subject to the same treatment as
U.S. shareholders with respect to such gain, or (ii) the Non-U.S. Shareholder is
a nonresident alien individual who was present in the U.S. for 183 days or more
during the taxable year and certain other conditions apply, in which case the
nonresident alien individual will be subject to a 30% tax on the individual's
capital gains.  If the gain on the sale of Shares were to be subject to taxation
under FIRPTA, the Non-U.S. Shareholder would be subject to the same treatment as
U.S. shareholders with respect to such gain (subject to applicable alternative
minimum tax, a special alternative minimum tax in the case of nonresident alien
individuals, and the possible application of the 30% branch profits tax in the
case of non-U.S. corporations).

OTHER TAX CONSEQUENCES

     The Company, the Operating Partnership, or the Company's shareholders may
be subject to state or local taxation in various state or local jurisdictions,
including those in which it or they own property, transact business, or reside.
The state and local tax treatment of the Company and its shareholders may not
conform to the federal income tax consequences discussed above.  CONSEQUENTLY,
PROSPECTIVE SHAREHOLDERS SHOULD CONSULT THEIR OWN TAX ADVISORS REGARDING THE
EFFECT OF STATE AND LOCAL TAX LAWS ON AN INVESTMENT IN THE COMPANY.

TAX ASPECTS OF THE OPERATING PARTNERSHIP

     The following discussion summarizes certain federal income tax
considerations applicable to the Company's direct or indirect investment in the
Operating Partnership.  The discussion does not cover state or local tax laws or
any federal tax laws other than income tax laws.

  Classification as a Partnership

     The Company will be entitled to include in its income its distributive
share of the Operating Partnership's income and to deduct its distributive share
of the Operating Partnership's losses only if the Operating Partnership is
classified for federal income tax purposes as a partnership rather than as a
corporation or an association taxable as a corporation.  An entity will be
classified as a partnership rather than as a corporation or an association
taxable as a corporation for federal income tax purposes if the entity (i) is
treated as a partnership under Treasury regulations, effective January 1, 1997,
relating to entity classification (the "Check-the-Box Regulations") and (ii) is
not a "publicly traded" partnership.  In general, under the Check-the-Box
Regulations, an unincorporated entity with at least two members may elect to be
classified either as an association taxable as a corporation or as a
partnership.  If such an entity fails to make an election, it generally will be
treated as a partnership for federal income tax purposes.  The Operating
Partnership intends to be classified as a partnership for federal income tax
purposes and will not elect to be treated as an association taxable as a
corporation under the Check-the-Box Regulations.

     A publicly traded partnership is a partnership whose interests are traded
on an established securities market or are readily tradable on a secondary
market (or the substantial equivalent thereof).  A publicly traded partnership
will be treated as a corporation for federal income tax purposes unless at least
90% of such partnership's gross income for a taxable year consists of
"qualifying income" under Section 7704(d) of the Code, which generally includes
any income that is qualifying income for purposes of the 95% gross income test
applicable to REITs (the "90% Passive-Type Income Exception").  See "--
Requirements for Qualification -- Income Tests."  The U.S. Treasury Department
has issued regulations (the "PTP Regulations") that provide limited safe harbors
from the definition of a publicly traded partnership.  Pursuant to one of those
safe harbors (the "Private Placement Exclusion"), interests in a partnership
will not be treated as readily tradable on a secondary market or the substantial
equivalent thereof if (i) all interests in the partnership were issued in a
transaction (or transactions) that was not required to be registered under the
Securities Act of 1933, as amended, and (ii) the partnership does not have more
than 100 partners at any time during the partnership's taxable year.  In
determining the number of partners in a partnership, a person owning an interest
in a flow-through entity (i.e., a partnership, grantor trust, or S corporation)
                          - -                                                  
that owns an interest in the partnership is treated as a partner in such
partnership only if (a) substantially all of the value of the owner's interest
in the flow-through entity is attributable to the flow-through entity's interest
(direct or indirect) in the partnership and (b) a principal purpose of the use
of the flow-through entity is to permit the partnership to satisfy the 100-
partner limitation.  The Operating Partnership qualifies for the Private
Placement Exclusion.  If the Operating Partnership is considered a publicly
traded partnership under the PTP Regulations because it is deemed to have more
than 100 partners, the Operating Partnership should not be treated as a
corporation because it should be eligible for the 90% Passive-Type Income
Exception.

     The Company has not requested, and does not intend to request, a ruling
from the Service that the Operating Partnership will be classified as a
partnership for federal income tax purposes.  Instead, Hunton & Williams is of
the opinion that, based on certain factual assumptions and representations, the
Operating Partnership will be treated for federal income tax purposes as a
partnership and not as a corporation or an association taxable as a corporation,
or as a publicly traded partnership.  Unlike a tax ruling, an opinion of counsel
is not binding upon the Service, and no assurance can be given that the Service
will not challenge the status of the Operating Partnership as a partnership for
federal income tax purposes.  If such challenge were sustained by a court, the
Operating Partnership would be treated as a corporation for federal income tax
purposes, as described below.  In addition, the opinion of Hunton & Williams is
based on existing law, which is to a great extent the result of administrative
and judicial interpretation.  No assurance can be given that administrative or
judicial changes would not modify the conclusions expressed in the opinion.

     If for any reason the Operating Partnership were taxable as a corporation,
rather than as a partnership, for federal income tax purposes, the Company would
not be able to qualify as a REIT.  See "Federal Income Tax Considerations --
Requirements for Qualification -- Income Tests" and "-- Requirements for
Qualification -- Asset Tests." In addition, any change in the Operating
Partnership's status for tax purposes might be treated as a taxable event, in
which case the Company might incur a tax liability without any related cash
distribution. See "Federal Income Tax Considerations -- Requirements for
Qualification -- Distribution Requirements." Further, items of income and
deduction of the Operating Partnership would not pass through to its partners,
and its partners would be treated as shareholders for tax purposes.
Consequently, the Operating Partnership would be required to pay income tax at
corporate tax rates on its net income, and distributions to its partners would
constitute dividends that would not be deductible in computing the Operating
Partnership's taxable income.

  Income Taxation of the Operating Partnerships and its Partners

     Partners, Not a Partnership, Subject to Tax.  A partnership is not a
taxable entity for federal income tax purposes.  Rather, the Company will be
required to take into account its allocable share of the Operating Partnership's
income, gains, losses, deductions, and credits for any taxable year of the
Operating Partnership ending within or with the taxable year of the Company,
without regard to whether the Company has received or will receive any
distribution from the Operating Partnership.

     Partnership Allocations.  Although a partnership agreement generally will
determine the allocation of income and losses among partners, such allocations
will be disregarded for tax purposes under section 704(b) of the Code if they do
not comply with the provisions of section 704(b) of the Code and the Treasury
Regulations promulgated thereunder.  If an allocation is not recognized for
federal income tax purposes, the item subject to the allocation will be
reallocated in accordance with the partners' interests in the partnership, which
will be determined by taking into account all of the facts 

                                       66
<PAGE>
 
and circumstances relating to the economic arrangement of the partners with
respect to such item. The Operating Partnership's allocations of taxable income
and loss are intended to comply with the requirements of section 704(b) of the
Code and the Treasury Regulations promulgated thereunder.

     Tax Allocations With Respect to Contributed Properties.  Pursuant to
section 704(c) of the Code, income, gain, loss, and deduction attributable to
appreciated or depreciated property that is contributed to a partnership in
exchange for an interest in the partnership must be allocated for federal income
tax purposes in a manner such that the contributor is charged with, or benefits
from, the unrealized gain or unrealized loss associated with the property at the
time of the contribution.  The amount of such unrealized gain or unrealized loss
is generally equal to the difference between the fair market value of the
contributed property at the time of contribution and the adjusted tax basis of
such property at the time of contribution.  The Treasury Department has issued
regulations requiring partnerships to use a "reasonable method" for allocating
items affected by section 704(c) of the Code and outlining several reasonable
allocation methods.  The Operating Partnership plans to elect to use the
traditional method for allocating Code section 704(c) items with respect to any
properties it acquires in exchange for OP Units.

     Under the Operating Partnership Agreement, depreciation or amortization
deductions of the Operating Partnership generally will be allocated among the
partners in accordance with their respective interests in the Operating
Partnership, except to the extent that the Operating Partnership is required
under Code section 704(c) to use a method for allocating tax depreciation
deductions attributable to its properties that results in the Company receiving
a disproportionately large share of such deductions.  Depending on the
allocation method elected under Code section 704(c), it is possible that the
Company (i) may be allocated lower amounts of depreciation deductions for tax
purposes with respect to contributed properties than would be allocated to the
Company if such properties were to have a tax basis equal to their fair market
value at the time of contribution and (ii) may be allocated taxable gain in the
event of a sale of such contributed properties in excess of the economic profit
allocated to the Company as a result of such sale.  These allocations may cause
the Company to recognize taxable income in excess of cash proceeds, which might
adversely affect the Company's ability to comply with the REIT distribution
requirements, although the Company does not anticipate that this event will
occur.  The foregoing principles also will affect the calculation of the
Company's earnings and profits for purposes of determining which portion of the
Company's distributions is taxable as a dividend.  The allocations described in
this paragraph may result in a higher portion of the Company's distributions
being taxed as a dividend than would have occurred had the Company purchased
such properties for cash.

     Basis in Operating Partnership Interest.  The Company's adjusted tax basis
in its partnership interest in the Operating Partnership generally is equal to
(i) the amount of cash and the basis of any other property contributed to the
Operating Partnership by the Company, (ii) increased by (A) its allocable share
of the Operating Partnership's income and (B) its allocable share of
indebtedness of the Operating Partnership, and (iii) reduced, but not below
zero, by (A) the Company's allocable share of the Operating Partnership's loss
and (B) the amount of cash distributed to the Company, including constructive
cash distributions resulting from a reduction in the Company's share of
indebtedness of the Operating Partnership.

     If the allocation of the Company's distributive share of the Operating
Partnership's loss would reduce the adjusted tax basis of the Company's
partnership interest in the Operating Partnership below zero, the recognition of
such loss will be deferred until such time as the recognition of such loss would
not reduce the Company's adjusted tax basis below zero.  To the extent that the
Operating Partnership's distributions, or any decrease in the Company's share of
the indebtedness of the Operating Partnership (such decrease being considered a
constructive cash distribution to the partners), would reduce the Company's
adjusted tax basis below zero, such distributions (including such constructive
distributions) will constitute taxable income to the Company.  Such
distributions and constructive distributions normally will be characterized as
capital gain, and, if the Company's partnership interest in the Operating
Partnership has been held for longer than the long-term capital gain holding
period (currently one year), the distributions and constructive distributions
will constitute long-term capital gain.

     Depreciation Deductions Available to the Operating Partnership.  Assuming
that the Minimum Offering is reached, immediately upon accepting a subscription,
the Company will make a cash contribution to the Operating Partnership in
exchange for a general partnership interest in the Operating Partnership.  The
Operating Partnership will use a portion of such contributions to acquire
interests in properties.  To the extent that the Operating Partnership acquires
properties for cash, the Operating Partnership's initial basis in such
properties for federal income tax purposes 

                                       67
<PAGE>
 
generally will be equal to the purchase price paid by the Operating Partnership.
The Operating Partnership plans to depreciate such depreciable property for
federal income tax purposes under the alternative depreciation system of
depreciation ("ADS"). Under ADS, the Operating Partnership generally will
depreciate such buildings and improvements over a 40-year recovery period using
a straight line method and a mid-month convention and will depreciate
furnishings and equipment over a 12-year recovery period. To the extent that the
Operating Partnership acquires properties in exchange for OP Units, the
Operating Partnership's initial basis in each such property for federal income
tax purposes should be the same as the transferor's basis in that property on
the date of acquisition by the Operating Partnership. Although the law is not
entirely clear, the Operating Partnership generally intends to depreciate such
depreciable property for federal income tax purposes over the same remaining
useful lives and under the same methods used by the transferors.

SALE OF THE OPERATING PARTNERSHIP'S PROPERTY

     Generally, any gain realized by the Operating Partnership on the sale of
property held for more than one year will be long-term capital gain, except for
any portion of such gain that is treated as depreciation or cost recovery
recapture.  Any gain recognized by the Operating Partnership upon the
disposition of a property acquired by the Operating Partnership for cash will be
allocated among the partners in accordance with their respective percentage
interests in the Operating Partnership.  The Bylaws of the Company provide that
any decision to sell any real estate asset in which a director, or officer of
the Company, or any Affiliate of the foregoing, has a direct or indirect
interest, will be made by a majority of the Directors including a majority of
the Independent Directors.  See "Policies with Respect to Certain Activities --
Conflict of Interest Policies -- Articles of Incorporation and Bylaw
Provisions."

     The Company's share of any gain realized by the Operating Partnership on
the sale of any property held by the Operating Partnership as inventory or other
property held primarily for sale to customers in the ordinary course of the
Operating Partnership's trade or business will be treated as income from a
prohibited transaction that is subject to a 100% penalty tax.  Such prohibited
transaction income also may have an adverse effect upon the Company's ability to
satisfy the income tests for REIT status.  See "Federal Income Tax
Considerations -- Requirements For Qualification -- Income Tests" above.  The
Company, however, does not presently intend to acquire or hold or allow the
Operating Partnership to acquire or hold any property that represents inventory
or other property held primarily for sale to customers in the ordinary course of
the Company's or the Operating Partnership's trade or business.

                              ERISA CONSIDERATIONS

     The following is a summary of material considerations arising under the
Employee Retirement Income Security Act of 1974, as amended ("ERISA"), and the
prohibited transaction provisions of section 4975 of the Code that may be
relevant to a prospective purchaser of Shares (including, with respect to the
discussion contained in "ERISA Considerations--Status of the Company and the
Operating Partnership under ERISA," to a prospective purchaser that is not an
employee benefit plan, another tax-qualified retirement plan, or an individual
retirement account or an individual retirement annuity ("IRA")).  The discussion
does not purport to deal with all aspects of ERISA or section 4975 of the Code
or, to the extent not preempted, state law that may be relevant to particular
shareholders (including plans subject to Title I of ERISA, other retirement
employee benefit plans and IRAs subject to the prohibited transaction provisions
of section 4975 of the Code, and governmental plans or church plans that are
exempt from ERISA and section 4975 of the Code but that may be subject to state
law requirements) in light of their particular circumstances.

     The discussion is based on current provisions of ERISA and the Code,
existing and currently proposed regulations under ERISA and the Code, the
legislative history of ERISA and the Code, existing administrative rulings of
the Department of Labor ("DOL") and reported judicial decisions.  No assurance
can be given that legislative, judicial, or administrative changes will not
affect the accuracy of any statements herein with respect to transactions
entered into or contemplated prior to the effective date of such changes.

     A FIDUCIARY MAKING THE DECISION TO INVEST IN THE SHARES ON BEHALF OF A
PROSPECTIVE PURCHASER THAT IS AN EMPLOYEE BENEFIT PLAN, A TAX-QUALIFIED
RETIREMENT PLAN, OR AN IRA SHOULD CONSULT ITS OWN LEGAL ADVISOR REGARDING THE
SPECIFIC 

                                       68
<PAGE>
 
CONSIDERATIONS ARISING UNDER ERISA, SECTION 4975 OF THE CODE, AND STATE LAW WITH
RESPECT TO THE PURCHASE, OWNERSHIP, OR SALE OF THE SHARES BY SUCH PLAN OR IRA.

EMPLOYEE BENEFIT PLANS, TAX-QUALIFIED RETIREMENT PLANS, AND IRAS

     Each fiduciary of a pension, profit-sharing, or other employee benefit plan
(an "ERISA Plan") subject to Title I of ERISA should consider carefully whether
an investment in the Shares is consistent with his fiduciary responsibilities
under ERISA.  In particular, the fiduciary requirements of Part 4 of Title I of
ERISA require an ERISA Plan's investments to be (i) prudent and in the best
interests of the ERISA Plan, its participants, and its beneficiaries, (ii)
diversified in order to minimize the risk of large losses, unless it is clearly
prudent not to do so, and (iii) authorized under the terms of the ERISA Plan's
governing documents (provided the documents are consistent with ERISA).  In
determining whether an investment in the Shares is prudent for purposes of
ERISA, the appropriate fiduciary of an ERISA Plan should consider all of the
facts and circumstances, including whether the investment is reasonably
designed, as a part of the ERISA Plan's portfolio for which the fiduciary has
investment responsibility, to meet the objectives of the ERISA Plan, taking into
consideration the risk of loss and opportunity for gain (or other return) from
the investment, the diversification, cash flow, and funding requirements of the
ERISA Plan, and the liquidity and current return of the ERISA Plan's portfolio.
A fiduciary also should take into account the nature of the Company's business,
the management of the Company, the Company's lack of operating history, the fact
that investment properties have not been identified yet, the possibility of the
recognition of UBTI, and other matters described under "Risk Factors."

     The fiduciary of an IRA or of a qualified retirement plan not subject to
Title I of ERISA because it is a governmental or church plan or because it does
not cover common law employees (a "Non-ERISA Plan") should consider that such an
IRA or Non-ERISA Plan may only make investments that are authorized by the
appropriate governing documents and under applicable state law.

     Fiduciaries of ERISA Plans and persons making the investment decision for
an IRA or other Non-ERISA Plan should consider the application of the prohibited
transaction provisions of ERISA and the Code in making their investment
decision.  A "party in interest" or "disqualified person" with respect to an
ERISA Plan or with respect to a Non-ERISA Plan or IRA subject to Code section
4975 is subject to (i) an initial 15% excise tax on the amount involved in any
prohibited transaction involving the assets of the plan or IRA and (ii) an
excise tax equal to 100% of the amount involved if any prohibited transaction is
not corrected.  If the disqualified person who engages in the transaction is the
individual on behalf of whom an IRA is maintained (or his beneficiary), the IRA
will lose its tax-exempt status and its assets will be deemed to have been
distributed to such individual in a taxable distribution (and no excise tax will
be imposed) on account of the prohibited transaction.  In addition, a fiduciary
who permits an ERISA Plan to engage in a transaction that the fiduciary knows or
should know is a prohibited transaction may be liable to the ERISA Plan for any
loss the ERISA Plan incurs as a result of the transaction or for any profits
earned by the fiduciary in the transaction.

STATUS OF THE COMPANY AND THE OPERATING PARTNERSHIP UNDER ERISA

     The following section discusses certain principles that apply in
determining whether the fiduciary requirements of ERISA and the prohibited
transaction provisions of ERISA and the Code apply to an entity because one or
more investors in the equity interests in the entity is an ERISA Plan or is a
Non-ERISA Plan or IRA subject to section 4975 of the Code.  An ERISA Plan
fiduciary also should consider the relevance of those principles to ERISA's
prohibition on improper delegation of control over or responsibility for "plan
assets" and ERISA's imposition of co-fiduciary liability on a fiduciary who
participates in, permits (by action or inaction) the occurrence of, or fails to
remedy a known breach by another fiduciary.

     If the assets of the Company are deemed to be "plan assets" under ERISA,
(i) the prudence standards and other provisions of Part 4 of Title I of ERISA
would be applicable to any transactions involving the Company's assets, (ii)
persons who exercise any authority over the Company's assets, or who provide
investment advice to the Company, would (for purposes of the fiduciary
responsibility provisions of ERISA) be fiduciaries of each ERISA Plan that
acquires Shares, and transactions involving the Company's assets undertaken at
their direction or pursuant to their advice might violate their fiduciary
responsibilities under ERISA, especially with regard to conflicts of interest,
(iii) a fiduciary exercising his investment discretion over the assets of an
ERISA Plan to cause it to acquire or hold the Shares could be 

                                       69
<PAGE>
 
liable under Part 4 of Title I of ERISA for transactions entered into by the
Company that do not conform to ERISA standards of prudence and fiduciary
responsibility, and (iv) certain transactions that the Company might enter into
in the ordinary course of its business and operations might constitute
"prohibited transactions" under ERISA and the Code.

     Regulations of the DOL defining "plan assets" (the "Plan Asset
Regulations") generally provide that when an ERISA Plan or Non-ERISA Plan or IRA
acquires a security that is an equity interest in an entity and the security is
neither a "publicly-offered security" nor a security issued by an investment
company registered under the Investment Company Act of 1940, the ERISA or Non-
ERISA Plan's or IRA's assets include both the equity interest and an undivided
interest in each of the underlying assets of the issuer of such equity interest,
unless one or more exceptions specified in the Plan Asset Regulations are
satisfied.

     The Plan Asset Regulations define a publicly-offered security as a security
that is (i) "widely-held," (ii) "freely transferable," and (iii) either (A) part
of a class of securities registered under Section 12(b) or 12(g) of the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), or (B) sold
pursuant to an effective registration statement under the Securities Act
(provided the securities are registered under the Exchange Act within 120 days
after the end of the fiscal year of the issuer during which the offering
occurred, or such longer period as may be allowed by the Commission).  The
Shares are being sold pursuant to an effective registration statement under the
Securities Act and will be registered under the Exchange Act.  The Plan Asset
Regulations provide that a security is "widely held" only if it is part of a
class of securities that is owned by 100 or more investors independent of the
issuer and of one another.  A security will not fail to be widely held because
the number of independent investors falls below 100 subsequent to the initial
public offering as a result of events beyond the issuer's control.  The Company
anticipates that upon completion of the Offering, the Shares will be "widely
held."

     The Plan Asset Regulations provide that whether a security is "freely
transferable" is a factual question to be determined on the basis of all
relevant facts and circumstances.  The Plan Asset Regulations further provide
that where a security is part of an offering in which the minimum investment is
$10,000 or less (as is the case with this Offering), certain restrictions
ordinarily will not, alone or in combination, affect a finding that such
securities are freely transferable.  The restrictions on transfer enumerated in
the Plan Asset Regulations as not affecting that finding include: (i) any
restriction on or prohibition against any transfer or assignment that would
result in the termination or reclassification of an entity for federal or state
tax purposes, or that otherwise would violate any federal or state law or court
order, (ii) any requirement that advance notice of a transfer or assignment be
given to the issuer, (iii) any administrative procedure that establishes an
effective date, or an event (such as completion of an offering), prior to which
a transfer or assignment will not be effective, and (iv) any limitation or
restriction on transfer or assignment that is not imposed by the issuer or a
person acting on behalf of the issuer.  The Company believes that the
restrictions imposed under the Articles of Incorporation on the transfer of the
Shares will not result in the failure of the Shares to be "freely transferable."
The Company also is not aware of any other facts or circumstances limiting the
transferability of the Shares that are not enumerated in the Plan Asset
Regulations as those not affecting free transferability, and the Company does
not intend to impose in the future (or to permit any person to impose on its
behalf) any limitations or restrictions on transfer that would not be among the
enumerated permissible limitations or restrictions.  The Plan Asset Regulations
only establish a presumption in favor of a finding of free transferability, and
no assurance can be given that the DOL or the Treasury Department will not reach
a contrary conclusion.

     Assuming that the Shares will be "widely held" and that no other facts and
circumstances other than those referred to in the preceding paragraph exist that
restrict transferability of the Shares, the Shares should be publicly offered
securities and the assets of the Company should not be deemed to be "plan
assets" of any ERISA Plan, IRA, or Non-ERISA Plan that invests in the Shares.

     The Plan Asset Regulations also will apply in determining whether the
assets of the Operating Partnership will be deemed to be "plan assets."  The
partnership interests in the Operating Partnership will not be publicly-offered
securities.  Nevertheless, if the Shares constitute publicly-offered securities,
the indirect investment in the Operating Partnership by ERISA Plans, IRAs, or
Non-ERISA Plans subject to section 4975 of the Code through their ownership of
Shares will not cause the assets of the Operating Partnership to be treated as
"plan assets" of such shareholders.

                             PARTNERSHIP AGREEMENT

     The following summary of the Partnership Agreement, and the descriptions of
certain provisions thereof set forth elsewhere in this Prospectus, is qualified
in its entirety by reference to the Partnership Agreement, which is filed as an
exhibit to the Registration Statement of which this Prospectus is a part.

MANAGEMENT

     The Operating Partnership has been organized as a Delaware limited
partnership pursuant to the terms of the Partnership Agreement.  Pursuant to the
Partnership Agreement, the Company, as the sole general partner of the Operating
Partnership (in such capacity, the "General Partner"), will have full, exclusive
and complete responsibility and discretion in the management and control of the
Operating Partnership, and the limited partners of the Operating Partnership
(the "Limited Partners"), in their capacity as such, will have no authority to
transact business for, or participate in the management activities or decisions
of, the Operating Partnership.  However, any amendment to the Partnership
Agreement that would (i) affect the Redemption Rights (as defined below), (ii)
adversely affect the Limited Partners' rights to receive cash distributions,
(iii) alter the Operating Partnership's allocations of income and loss or (iv)
impose on the Limited Partners any obligations to make additional contributions
to the capital of the Operating Partnership, would require the consent of
Limited Partners holding more than two-thirds of the OP Units.

TRANSFERABILITY OF INTERESTS IN THE OPERATING PARTNERSHIP

     The Company may not voluntarily withdraw from the Operating Partnership or
transfer or assign its interest in the Operating Partnership unless the
transaction in which such withdrawal or transfer occurs results in the Limited
Partners' receiving property in an amount equal to the amount they would have
received had they exercised their Redemption Rights immediately prior to such
transaction, or unless the successor to the General Partner contributes
substantially all of its assets to the Operating Partnership in return for an
interest in the Operating Partnership.  A person may not be admitted as a
substitute or successor General Partner unless a majority-in-interest of the
Limited Partners (other than the Advisor) consent in writing to the admission of
such substitute or successor General Partner, which consent may be withheld in
the sole discretion of such Limited Partners.  With certain limited exceptions,
the Limited Partners may not transfer their interests in the Operating
Partnership, in whole or in part, without the written consent of the Company,
which consent may be withheld in the sole discretion of the Company.

CAPITAL CONTRIBUTION

     As the Company accepts subscriptions, it will contribute to the Operating
Partnership substantially all of the net proceeds thereof, in consideration of
which the Company will receive a general partnership interest in the Operating
Partnership.  The Advisor has contributed $200,000 to the Operating Partnership
and is the sole initial Limited Partner.  Although the Operating Partnership
will receive substantially all of the net proceeds of the Offering, the Company
will be deemed to have made capital contributions to the Operating Partnership
in the amount of the gross proceeds of the Offering and the Operating
Partnership will be deemed simultaneously to have paid the selling commissions
and other Organization and Offering Expenses.  The Partnership Agreement
provides that if the Operating Partnership requires additional funds at any time
or from time to time in excess of funds available to the Operating Partnership
from borrowing or capital contributions, the Company may borrow such funds from
a financial institution or other lender and lend such funds to the Operating
Partnership on the same terms and conditions as are applicable to the Company's
borrowing of such funds.  Moreover, the Company is authorized to cause the
Operating Partnership to issue partnership interests for less than fair market
value if the Company has concluded in good faith that such issuance is in the
best interests of the Company and the Operating Partnership.

REDEMPTION RIGHTS

     Pursuant to the Partnership Agreement, the Limited Partners, other than the
Advisor, will receive rights (the "Redemption Rights"), which will enable them
to cause the Operating Partnership to redeem each OP Unit for cash equal to the
value of one Share (or, at the Company's election, the Company may purchase each
OP Unit offered for redemption for one Share).  The Redemption Rights may not be
exercised, however, if and to the extent that the delivery 

                                       71
<PAGE>
 
of Shares upon exercise of such rights (regardless of whether the Company would
exercise its rights to deliver Shares) would (i) result in any person owning,
directly or indirectly, Shares in excess of the Ownership Limitation, (ii)
result in shares of capital stock of the Company being owned by fewer than 100
persons (determined without reference to any rules of attribution), (iii) result
in the Company being "closely held" within the meaning of section 856(h) of the
Code, (iv) cause the Company to own, actually or constructively, 10% or more of
the ownership interests in a tenant of the Company's or the Operating
Partnership's real property, within the meaning of section 856(d)(2)(B) of the
Code, or (v) cause the acquisition of Shares by such redeeming Limited Partner
to be "integrated" with any other distribution of Shares for purposes of
complying with the Securities Act. The Redemption Rights may be exercised, at
any time after one year following the date of issuance of the related OP Units,
provided that not more than two redemptions may occur during each calendar year
and each Limited Partner may not exercise the Redemption Right for less than
1,000 OP Units or, if such Limited Partner holds less than 1,000 OP Units, all
of the OP Units held by such Limited Partner. The number of Shares issuable upon
exercise of the Redemption Rights will be adjusted upon the occurrence of share
splits, mergers, consolidations or similar pro rata share transactions, which
otherwise would have the effect of diluting the ownership interests of the
Limited Partners or the shareholders of the Company. As of the date hereof, the
Company has not issued any OP Units other than to the Advisor and has no current
intentions to issue OP Units.

OPERATIONS

     The Partnership Agreement requires that the Operating Partnership be
operated in a manner that will enable the Company to satisfy the requirements
for being classified as a REIT, to avoid any federal income or excise tax
liability imposed under the Code and to ensure that the Operating Partnership
will not be classified as a "publicly traded partnership" for purposes of
section 7704 of the Code.

     In addition to the administrative and operating costs and expenses incurred
by the Operating Partnership, the Operating Partnership will pay all
administrative costs and expenses of the Company (the "Company Expenses") and
the Company Expenses will be treated as expenses of the Operating Partnership.
The Company Expenses generally will include (i) all expenses relating to the
formation and continuity of existence of the Company, (ii) all expenses relating
to the public offering and registration of securities by the Company, (iii) all
expenses associated with the preparation and filing of any periodic reports by
the Company under federal, state or local laws or regulations, (iv) all expenses
associated with compliance by the Company with laws, rules and regulations
promulgated by any regulatory body and (v) all other operating or administrative
costs of the Company incurred in the ordinary course of its business on behalf
of the Operating Partnership.  The Company Expenses, however, will not include
any administrative and operating costs and expenses incurred by the Company that
are attributable to properties or partnership interests that are owned by the
Company directly.  The Company currently does not anticipate owning any
properties directly.

DISTRIBUTIONS AND ALLOCATIONS

     The Partnership Agreement will provide that the Operating Partnership will
distribute cash from operations (including net sale or refinancing proceeds, but
excluding net proceeds from the sale of the Operating Partnership's property in
connection with the liquidation of the Operating Partnership) on a quarterly
(or, at the election of the Company, more frequent) basis, in amounts determined
by the Company in its sole discretion, to the partners in accordance with their
respective percentage interests in the Operating Partnership.  Upon liquidation
of the Operating Partnership, after payment of, or adequate provision for, debts
and obligations of the Operating Partnership, including any partner loans, any
remaining assets of the Operating Partnership will be distributed to all
partners with positive capital accounts in accordance with their respective
positive capital account balances.  If the Company has a negative balance in its
capital account following a liquidation of the Operating Partnership, it will be
obligated to contribute cash to the Operating Partnership equal to the negative
balance in its capital account.

     Profit and loss of the Operating Partnership for each fiscal year of the
Operating Partnership generally will be allocated among the partners in
accordance with their respective interests in the Operating Partnership.
Taxable income and loss will be allocated in the same manner, subject to
compliance with the provisions of Code sections 704(b) and 704(c) and Treasury
Regulations promulgated thereunder.

                                       72

TERM

     The Operating Partnership will continue until December 31, 2050, or until
sooner dissolved upon the sale or other disposition of all or substantially all
the assets of the Operating Partnership, the redemption of all limited
partnership interests in the Operating Partnership (other than those held by the
Advisor), or by the election by the Company.

TAX MATTERS

     Pursuant to the Partnership Agreement, the Company will be the tax matters
partner of the Operating Partnership and, as such, will have authority to handle
tax audits and to make tax elections under the Code on behalf of the Operating
Partnership.

                              PLAN OF DISTRIBUTION

     Of the total 16,5000,000 shares registered in the Offering, 1,500,000 are
reserved for issuance pursuant to the Reinvestment Plan and 600,000 are reserved
for issuance upon exercise of the Soliciting Dealer Warrants.  Consequently, a
maximum of 14,400,000 Shares are being offered to the public through the Dealer
Manager, a registered broker-dealer affiliated with the Advisor, and certain
unaffiliated broker-dealers.  See "Conflicts of Interest" and "Management
Compensation."  The Shares are being offered at a price of $10.00 per share on a
"best efforts" basis (which means generally that the Dealer Manager will be
required to use only its best efforts to sell the Shares and has no firm
commitment or obligation to purchase any of the Shares).  The Company and the
Dealer Manager have determined the Offering price of the Shares based on their
analysis of other similar offerings and what they believe the investing market
is willing to pay for the Shares.

     Except as provided below, the Dealer Manager will receive commissions of 7%
of the Gross Offering Proceeds.  In addition, the Company may reimburse the
expenses incurred by the Dealer Manager and nonaffiliated dealers for actual
marketing support and due diligence purposes in the maximum amount of 2.5% of
the Gross Offering Proceeds.  The Company will not pay referral or similar fees
to any accountants, attorneys or other persons in connection with the
distribution of the Shares.  Shareholders who elect to participate in the
Reinvestment Plan will be charged Selling Commissions on Shares purchased
pursuant to the Reinvestment Plan on the same basis as shareholders purchasing
Shares other than pursuant to the Reinvestment Plan.   Soliciting Dealers will
also receive one Soliciting Dealer Warrant for each 25 Shares sold by such
Soliciting Dealer during the Offering, subject to federal and state securities
laws.  The holder of a Soliciting Dealer Warrant will be entitled to purchase
one Share from the Company at a price of $12 during the period commencing on the
first anniversary of the effective date of this Offering and ending five years
after the effective date of this Offering.  Subject to certain limitations, the
Soliciting Dealer Warrants may not be transferred, assigned, pledged or
hypothecated for a period of one year following the effective date of this
Offering.  The Shares issuable upon exercise of the Soliciting Dealer Warrants
are being registered as part of this Offering.  For the life of the Soliciting
Dealer Warrants, the holders are given, at nominal cost, the opportunity to
profit from a rise in the market price for the Common Stock without assuming the
risk of ownership, with a resulting dilution in the interest of other security
holders.  Moreover, the holders of the Soliciting Dealer Warrants might be
expected to exercise them at a time when the Company would, in all likelihood,
be able to obtain needed capital by a new offering of its securities on terms
more favorable than those provided by the Soliciting Dealer Warrants.  See
"Description of Capital Stock -- Soliciting Dealer Warrants."

     The Dealer Manager may authorize certain other broker-dealers who are
members of the NASD to sell Shares.  In the event of the sale of Shares by such
other broker-dealers, the Dealer Manager may reallow its commissions in the
amount of up to 7% of the Gross Offering Proceeds to such participating broker-
dealers.

     In no event shall the total underwriting compensation, including Selling
Commissions and expense reimbursements, exceed 7% of Gross Offering Proceeds,
except for the additional Marketing and Due Diligence Fee (2.5% of Gross
Offering Proceeds), which may be paid by the Company in connection with
marketing support and due diligence activities, which is comprised of .5% for
due diligence activities and 2% for marketing support activities.

                                       73
<PAGE>
 
     The Company has agreed to indemnify the participating broker-dealers,
including the Dealer Manager, against certain liabilities arising under the
Securities Act of 1933, as amended.  Causes of action resulting from violations
of federal or state securities laws shall be governed by such law.

     The broker-dealers are not obligated to obtain any subscriptions, and there
is no assurance that any Shares will be sold.

     The Advisor and its Affiliates may at their option purchase Shares offered
hereby at the public offering price, in which case it would expect to hold such
Shares as shareholders for investment and not for distribution.  Shares
purchased by the Advisor or its Affiliates shall not be entitled to vote on any
matter presented to the shareholders for a vote.  No selling commissions will be
payable by the Company in connection with any Shares purchased by the Advisor.

     Payment for Shares should be made by check payable to "NationsBank, N.A.,
as Escrow Agent"  Subscriptions will be effective only upon acceptance by the
Company, and the Company reserves the right to reject any subscription in whole
or in part.  In no event may a subscription for Shares be accepted until at
least five business days after the date the subscriber receives this Prospectus.
Each subscriber will receive a confirmation of his purchase.  Except for
purchase pursuant to the Reinvestment Plan, all accepted subscriptions will be
for whole Shares and for not less than 100 Shares ($1,000).  See "Investor
Suitability Standards."  Except in Maine, Minnesota and Washington, investors
who have satisfied the minimum purchase requirement and have purchased units in
Prior Wells Public Programs may purchase less than the minimum number of Shares
discussed above, provided that such investors purchase a minimum of 2.5 Shares
($25).  After investors have satisfied the minimum purchase requirement, minimum
additional purchases must be in increments of at least 2.5 Shares ($25), except
for purchases pursuant to the Reinvestment Plan.

     Subscription proceeds will be placed in interest-bearing accounts with the
Escrow Agent by noon of the business day after the proceeds are received by the
Company until such subscriptions aggregating at least $1,250,000 (exclusive of
any subscriptions for Shares by the Advisor or its Affiliates) have been
received and accepted by the Advisor (the "Minimum Offering").  Any Shares
purchased by the Advisor or its Affiliates will not be counted in calculating
the Minimum Offering.  Subscription proceeds held in the escrow accounts will be
invested in obligations of, or obligations guaranteed by, the United States
government or bank money-market accounts or certificates of deposit of national
or state banks that have deposits insured by the Federal Deposit Insurance
Corporation (including certificates of deposit of any bank acting as depository
or custodian for any such funds), as directed by the Advisor.  Subscribers may
not withdraw funds from the escrow account.

     Investors who desire to establish an IRA for purposes of investing in
Shares may do so by having Wells Advisors, Inc., a qualified non-bank IRA
custodian affiliated with the Advisor, act as their IRA custodian.  In the event
that an IRA is established having Wells Advisors, Inc. as the IRA custodian, the
authority of Wells Advisors, Inc. will be limited to holding the Shares on
behalf of the beneficiary of the IRA and making distributions or reinvestments
in Shares solely at the discretion of the beneficiary of the IRA.  Wells
Advisors, Inc. will not have the authority to vote any of the Shares held in an
IRA except strictly in accordance with the written instructions of the
beneficiary of the IRA.  See "Management."

     If the Minimum Offering has not been received and accepted by January 30,
1999 (one year after the date of this Prospectus), the Escrow Agent will
promptly so notify the Company and this Offering will be terminated.  In such
event, the Escrow Agent is obligated to use its best efforts to obtain an
executed IRS Form W-9 from each subscriber whose subscription is rejected.  No
later than ten business days after rejection of a subscription, the Escrow Agent
will refund and return all monies to rejected subscribers and any interest
earned thereon without deducting escrow expenses.  In the event that a
subscriber fails to remit an executed IRS Form W-9 to the Escrow Agent prior to
the date the Escrow Agent returns the subscriber's funds, the Escrow Agent will
be required to withhold from such funds 31% of the earnings attributable to such
subscriber in accordance with IRS Regulations.  During any period in which
subscription proceeds are held in escrow, interest earned thereon will be
allocated among subscribers on the basis of the respective amounts of their
subscriptions and the number of days that such amounts were on deposit.  Such
interest net of escrow expenses will be paid to subscribers upon the termination
of the escrow period.

                                       74
<PAGE>
 
     Initial subscribers may be admitted as shareholders of the Company and the
payments transferred from escrow to the Company at any time after the Company
has received and accepted the Minimum Offering, except that subscribers residing
in New York and Pennsylvania may not be admitted to the Company until
subscriptions have been received and accepted for 250,000 Shares ($2,500,000)
from all sources.  The funds representing subscriptions for Shares from New York
and Pennsylvania residents will not be released from the escrow account until
subscriptions for at least $2,500,000 have been received from all sources.
Subscriptions from New York residents may not be included in determining whether
subscriptions for the Minimum Offering have been obtained.  In addition, certain
other states may impose different requirements than those set forth herein.  Any
such additional requirements will be set forth in a supplement to this
Prospectus.

     The proceeds of this Offering will be received and held in trust for the
benefit of purchasers of Shares and will be retained in trust after closing to
be used only for the purposes set forth in the "Estimated Use of Proceeds"
section.  After the close of the Minimum Offering, subscriptions will be
accepted or rejected within 30 days of receipt by the Company, and if rejected,
all funds shall be returned to subscribers within 10 business days.  Investors
whose subscriptions are accepted will be admitted as shareholders of the Company
periodically (but not less often than quarterly).  Escrowed proceeds will be
released to the Company on the date that the applicable Shareholder is admitted
to the Company.  A Shareholder will not receive a Share certificate or other
evidence of his interest in the Company unless the Listing occurs, and then only
if requested by the Shareholder.

     The Advisor may sell Shares to Retirement Plans of broker-dealers
participating in the Offering, to broker-dealers in their individual capacities,
to IRAs and Qualified Plans of their registered representatives or to any one of
their registered representatives in their individual capacities for 93% of the
Share's public offering price in consideration of the services rendered by such
broker-dealers and registered representatives in the distribution.  The net
proceeds to the Company from such sales will be identical to the Company's net
proceeds from other sales of Shares.

     In connection with sales of 25,000 or more Shares ($250,000) to a
"purchaser" (as defined below), investors may agree with their registered
representatives to reduce the amount of selling commissions payable to
participating broker-dealers.  Such reduction will be credited to the purchaser
by reducing the total purchase price payable by such purchaser.  The following
table illustrates the various discount levels:

</TABLE>

     For example, if an investor purchases 100,000 Shares in the Company, he
could pay as little as $939,390 rather than $1,000,000 for the Shares, in which
event the commission on the sale of such Shares would be $9,390 ($0.0939 per
Share), and the Company would receive net proceeds of $930,000 ($9.30 per
Share).  The net proceeds to the Company will not be affected by volume
discounts.

     Because all investors will be deemed to have contributed the same amount
per Share to the Company for purposes of distributions of Cash Available for
Distribution, an investor qualifying for a volume discount will receive a higher
return on his investment in the Company than investors who do not qualify for
such discount.

     Subscriptions may be combined for the purpose of determining the volume
discounts in the case of subscriptions made by any "purchaser," as that term is
defined below, provided all such Shares are purchased through the same broker-
dealer.  The volume discount shall be prorated among the separate subscribers
considered to be a single "purchaser."  Any request to combine more than one
subscription must be made in writing, and must set forth the basis 

                                       75
<PAGE>
 
for such request. Any such request will be subject to verification by the
Advisor that all of such subscriptions were made by a single "purchaser."

     For the purposes of such volume discounts, the term "purchaser" includes
(i) an individual, his or her spouse and their children under the age of 21 who
purchase the Shares for his, her or their own accounts; (ii) a corporation,
partnership, association, joint-stock company, trust fund or any organized group
of persons, whether incorporated or not; (iii) an employees' trust, pension,
profit sharing or other employee benefit plan qualified under Section 401(a) of
the Code; and (iv) all commingled trust funds maintained by a given bank.

     Notwithstanding the above, in connection with volume sales made to
investors in the Company, the Company may, in its sole discretion, waive the
"purchaser" requirements and aggregate subscriptions (including subscriptions to
Prior Wells Public Programs) as part of a combined order for purposes of
determining the number of Shares purchased, provided that any aggregate group of
subscriptions must be received from the same broker-dealer, including the Dealer
Manager.  Any such reduction in selling commission will be prorated among the
separate subscribers except that, in the case of purchases through the Dealer
Manager, the Dealer Manager may allocate such reduction among separate
subscribers considered to be a single "purchaser" as it deems appropriate.  An
investor may reduce the amount of his purchase price to the net amount shown in
the foregoing table, if applicable.  If such investor does not reduce the
purchase price, the excess amount submitted over the discounted purchase price
shall be returned to the actual separate subscribers for Shares.  Except as
provided in this paragraph, separate subscriptions will not be cumulated,
combined or aggregated.

     In addition, in order to encourage purchases in amounts of 500,000 or more
Shares, a potential purchaser who proposes to purchase at least 500,000 Shares
in the Company may agree with the Advisor and the Dealer Manager to have the
Acquisition and Advisory Fees payable to the Advisor with respect to the sale of
such Shares reduced to 0.5%, and to have the Selling Commissions payable with
respect to the sale of such Shares reduced to 0.5%, in which event the aggregate
fees payable with respect to the sale of such Shares would be reduced by $0.90
per Share, and the purchaser of such Shares would be required to pay a total of
$9.10 per Share purchased, rather than $10.00 per Share.  The net proceeds to
the Company would not be affected by such fee reductions.  Of the $9.10 paid per
Share, it is anticipated that approximately $8.40 per Share (or approximately
92%) will be used to acquire properties and pay required acquisition expenses
relating to the acquisition of properties.  All such sales must be made through
registered broker-dealers.

     California residents should be aware that volume discounts will not be
available in connection with the sale of Shares made to California residents to
the extent such discounts do not comply with the provisions of Rule 260.140.51
adopted pursuant to the California Corporate Securities Law of 1968.  Pursuant
to this Rule, volume discounts can be made available to California residents
only in accordance with the following conditions: (i) there can be no variance
in the net proceeds to the Company from the sale of the Shares to different
purchasers of the same offering, (ii) all purchasers of the Shares must be
informed of the availability of quantity discounts, (iii) the same volume
discounts must be allowed to all purchasers of Shares which are part of the
offering, (iv) the minimum amount of Shares as to which volume discounts are
allowed cannot be less than $10,000, (v) the variance in the price of the Shares
must result solely from a different range of commissions, and all discounts
allowed must be based on a uniform scale of commissions, and (vi) no discounts
are allowed to any group of purchasers.  Accordingly, volume discounts for
California residents will be available in accordance with the foregoing table of
uniform discount levels based on dollar volume of Shares purchased, but no
discounts are allowed to any group of purchasers, and no subscriptions may be
aggregated as part of a combined order for purposes of determining the number of
Shares purchased.

     Investors who, in connection with their purchase of Shares, have engaged
the services of a registered investment advisor with whom the investor has
agreed to pay a fee for investment advisory services in lieu of normal
commissions based on the volume of securities sold may agree with the
participating broker-dealer selling such Shares and the Dealer Manager to reduce
the amount of selling commissions payable with respect to such sale to zero.
The net proceeds to the Company will not be affected by eliminating the
commissions payable in connection with sales to investors purchasing through
such investment advisors.  All such sales must be made through registered
broker-dealers.

                                       76
<PAGE>
 
     Neither the Dealer Manager nor its Affiliates will directly or indirectly
compensate any person engaged as an investment advisor by a potential investor
as an inducement for such investment advisor to advise favorably for investment
in the Company.

     In addition, subscribers for Shares may agree with their participating
broker-dealers and the Dealer Manager to have selling commissions due with
respect to the purchase of their Shares paid over a seven year period pursuant
to a deferred commission arrangement (the "Deferred Commission Option").
Shareholders electing the Deferred Commission Option will be required to pay a
total of $9.40 per Share purchased upon subscription, rather than $10.00 per
Share, with respect to which $0.10 per Share will be payable as commissions due
upon subscription.  For each of the six years following termination of the
Offering, $0.10 per Share will be paid by the Company as deferred commissions
with respect to Shares sold pursuant to the Deferred Commission Option, which
amounts will be deducted from and paid out of distributions of Cash Available
for Distribution otherwise payable to shareholders holding such Shares.  The net
proceeds to the Company will not be affected by the election of the Deferred
Commission Option.  Under this arrangement, a Shareholder electing the Deferred
Commission Option will pay a 1% commission upon subscription, rather than an 7%
commission, and an amount equal to a 1% commission per year thereafter for the
next six years will be deducted from and paid by the Company out of Cash
Available for Distribution otherwise distributable to such Shareholder.

     Taxable participants electing the Deferred Commission Option will incur tax
liability for Company income allocated to them with respect to their Shares even
though distributions of Cash Available for Distribution otherwise distributable
to such shareholders will instead be paid to third parties to satisfy the
deferred commission obligations with respect to such Shares for a period of six
years after the termination of the Offering.  See "Risk Factors - Federal Tax
Risks - Risk of Taxable Income Without Cash Distributions."

     As set forth above, in no event shall the total underwriting compensation,
including sales commissions, the dealer manager fee and expense reimbursements,
exceed 7% of Gross Offering Proceeds, except for the additional .5% of Gross
Offering Proceeds which may be paid by the Company in connection with due
diligence activities and 2% of Gross Offering Proceeds which may be paid by the
Company in connection with marketing support activities.

                          SUPPLEMENTAL SALES MATERIAL

     In addition to this Prospectus, the Company may utilize certain sales
material in connection with the Offering of the Shares, although only when
accompanied by or preceded by the delivery of this Prospectus.  In certain
jurisdictions, some or all of such sales material may not be available.  This
material may include information relating to this Offering, the past performance
of the Advisor and its Affiliates, property brochures and articles and
publications concerning real estate.  In addition, the sales material may
contain certain quotes from various publications without obtaining the consent
of the author or the publication for use of the quoted material in the sales
material.

     The Offering of Shares in the Company is made only by means of this
Prospectus.  Although the information contained in such sales material does not
conflict with any of the information contained in this Prospectus, such material
does not purport to be complete, and should not be considered a part of this
Prospectus or the Registration Statement of which this Prospectus is a part, or
as incorporated by reference in this Prospectus or said Registration Statement
or as forming the basis of the Offering of the Shares.

                                 LEGAL MATTERS

     The legality of the Shares being offered hereby has been passed upon for
the Company by Hunton & Williams, Atlanta, Georgia ("Counsel").  The statements
under the caption "Federal Income Tax Consequences" as they relate to federal
income tax matters have been reviewed by Counsel, and Counsel has opined as to
certain income tax matters relating to an investment in the Company.  Counsel
has represented the Advisor, as well as Affiliates of the Advisor, in other
matters and may continue to do so in the future.  See "Conflicts of Interest."

                      NOTES TO CONSOLIDATED BALANCE SHEET

                               DECEMBER 31, 1997

(1)  ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     Wells Real Estate Investment Trust, Inc. (the "Company"), is a newly formed
     Maryland corporation that intends to qualify as a real estate investment
     trust ("REIT").  The Company intends to offer for sale a maximum of
     15,000,000 (exclusive of 1,500,000 shares available pursuant to the
     Company's dividend reinvestment plan) shares of common stock, $.01 par
     value per share, at a price of $10 per share.  As of December 31, 1997, the
     Company had sold 100 shares to Wells Capital, Inc. (the "Advisor"), at the
     proposed initial public offering price of $10 per share.  The Company will
     seek to acquire and operate commercial properties, including, but not
     limited to, office buildings, shopping centers, business and industrial
     parks, and other commercial and industrial properties, including properties
     which are under construction or development, are newly constructed, or have
     been constructed and have operating histories.  All such properties may be
     acquired, developed and operated by the Company alone or jointly with
     another party.  The Company is likely to enter into one or more joint
     ventures with affiliated entities for the acquisition of properties.  In
     connection with this, the Company may enter into joint ventures for the
     acquisition of properties with prior or future real estate limited
     partnership programs sponsored by the Advisor or its affiliates.

     Substantially all of the Company's business will be conducted through Wells
     Operating Partnership, L.P. (the "Operating Partnership"), a Delaware
     limited partnership.  At December 31, 1997, the Operating Partnership had
     issued 20,000 limited partner units to the Advisor in exchange for
     $200,000.  The Company is the sole general partner in the Operating
     Partnership and possesses full legal control and authority over the
     operations of the Operating Partnership; consequently, the accompanying
     consolidated balance sheet of the Company includes the amounts of the
     Company and the Operating Partnership.

     As of December 31, 1997, the Company has neither purchased nor contracted
     to purchase any properties, nor has the Advisor identified any properties
     in which there is a reasonable probability that the Company will invest.

     USE OF ESTIMATES

     The preparation of the consolidated balance sheet in conformity with
     generally accepted accounting principles requires management to make
     estimates and assumptions that affect the reported amounts of assets and
     liabilities and disclosure of contingent assets and liabilities at the date
     of the consolidated balance sheet.  Actual results could differ from those
     estimates.


(2)  INCOME TAXES

     The Company expects to qualify as a REIT under the Internal Revenue Code of
     1986, as amended.  As a REIT, the Company generally will not be subject to
     federal income tax on net income that it distributes to its shareholders.
     The Company intends to make timely distributions sufficient to satisfy the
     annual distribution requirements.

                            PRIOR PERFORMANCE TABLES

     The following Prior Performance Tables (the "Tables") provide information
relating to real estate investment programs sponsored by the Advisor and its
Affiliates ("Prior Programs") which have investment objectives similar to the
Company.

     Prospective investors should read these Tables carefully together with the
summary information concerning the Prior Programs as set forth in "PRIOR
PERFORMANCE SUMMARY" elsewhere in this Prospectus.

     INVESTORS IN THE COMPANY WILL NOT OWN ANY INTEREST IN THE PRIOR PROGRAMS
AND SHOULD NOT ASSUME THAT THEY WILL EXPERIENCE RETURNS, IF ANY, COMPARABLE TO
THOSE EXPERIENCED BY INVESTORS IN THE PRIOR PROGRAMS.

     These Tables present actual results of Wells Prior Public Programs that
have investment objectives similar to those of the Company.  The Company's
investment objectives are to maximize Net Cash From Operations; to preserve
original Capital Contributions; and to realize capital appreciation over a
period of time.  All of the Wells Prior Public Programs have used a substantial
amount of capital and not acquisition indebtedness to acquire their properties.

     The Advisor is responsible for the acquisition, operation, maintenance and
resale of the Partnership Properties.  The financial results of the Prior
Programs thus provide an indication of the Advisor's performance of its
obligations during the periods covered.  However, general economic conditions
affecting the real estate industry and other factors contribute significantly to
financial results.

     The following tables are included herein:

     TABLE I - Experience in Raising and Investing Funds (As a Percentage of
Investment)

     TABLE II - Compensation to Sponsor (in Dollars)

     TABLE III - Annual Operating Results of Prior Programs

     TABLE IV (Results of completed programs) and TABLE V (sales or disposals of
property) have been omitted since none of the Prior Programs have sold any of
their properties to date.

     Additional information relating to the acquisition of properties by the
Prior Programs is contained in TABLE VI, which is included in the Registration
Statement which the Company has filed with the Securities and Exchange
Commission.  As described above, no Wells Prior Public Program has sold or
disposed of any property held by it.  Copies of any or all information will be
provided to prospective investors at no charge upon request, including copies of
the Form 10-K Annual Report for any or all of the Prior Programs for any
available year.

     The following are definitions of certain terms used in the Tables:

     "ACQUISITION FEES" shall mean fees and commissions paid by a partnership in
connection with its purchase or development of a property, except Development
fees paid to a person not affiliated with the partnership or with a general
partner of the partnership in connection with the actual development of a
project after acquisition of the land by the partnership.

     "ORGANIZATION EXPENSES" shall include legal fees, accounting fees,
securities filing fees, printing and reproduction expenses and fees paid to the
general partners or their affiliates in connection with the planning and
formation of the partnership.

     "UNDERWRITING FEES" shall include selling commissions and wholesaling fees
paid to broker-dealers for services provided by the broker-dealers during the
offering.

                           DIVIDEND REINVESTMENT PLAN


Wells Real Estate Investment Trust, Inc., a Maryland corporation (the
"Company"), pursuant to its Articles of Incorporation, as amended and restated
to date (the "Articles"), has adopted a Dividend Reinvestment Plan (the "DRP"),
the terms and conditions of which are set forth below.  Capitalized terms shall
have the same meaning as set forth in the Articles unless otherwise defined
herein.

     1.  As agent for stockholders ("Stockholders") of the Company who purchase
shares of the Company's common stock (the "Shares") pursuant to the Company's
public offering which commenced January 30, 1998, which offering is expected to
be completed within one year from the date of such effectiveness (the
"Offering") and who elect to participate in the DRP (the "Participants), the
Company will apply all dividends and other distributions declared and paid in
respect of the Shares held by each Participant (the "Distributions"), including
Distributions paid with respect to any full or fractional Shares acquired under
the DRP, to the purchase of the Shares for such Participants directly, if
permitted under state securities laws and, if not, through the Dealer-Manager
for Participating Dealers registered in the Participant's state of residence.
Neither the Company nor its Affiliates will receive a fee for selling Shares
under the DRP.

     2.  Procedure for Participation.  Any Stockholder who purchased Shares
         ---------------------------                                       
pursuant to the Company's Offering may elect to become a Participant by
completing and executing the Subscription Agreement, enrollment form or other
appropriate authorization form as may be available from the Company, the Dealer-
Manager or Soliciting Dealer.  Participation in the DRP will begin with the next
Distribution payable after receipt of a Participant's subscription or
authorization.  Shares will be purchased under the DRP on the record date for
the Distribution used to purchase the Shares.  Distributions for Shares acquired
under the DRP are currently paid monthly and are calculated with a daily record
and Distribution declaration date.  Each Participant agrees that if, at any time
prior to listing of the Shares on a national stock exchange or inclusion of the
Shares for quotation on the National Association of Securities Dealers, Inc.
Automated Quotation System ("Nasdaq"), he or she fails to meet the suitability
requirements for making an investment in the Company or cannot make the other
representations or warranties set forth in the Subscription Agreement, he will
promptly so notify the Company in writing.

     3.  Purchase of Shares.  Participants will acquire Shares from the Company
         ------------------                                                    
at a fixed price of $10 per Share until all 1,500,000 Initial DRP Shares (as
defined) are issued.  Participants in the DRP may also purchase fractional
Shares so that 100% of the Distributions will be used to acquire Shares.
However, a Participant will not be able to acquire Shares under the DRP to the
extent such purchase would cause it to exceed the Ownership Limit.

     Shares to be distributed by the Company in connection with the DRP may (but
are not required to) be supplied from:  (a) 1,500,000 Shares which were
registered for the DRP in the Offering (the "Initial DRP Shares"), (b) shares of
the Company's stock purchased by the Company for the DRP in a secondary market
(if available) or on a stock exchange or Nasdaq (if listed) (collectively, the
"Secondary Market"), or (c) shares registered by the Company with the SEC for
use in the DRP (a "Secondary Registration").

     Shares purchased on the Secondary Market as set forth in (b) above will be
purchased at the then-prevailing market price, which price will be utilized for
purposes of purchases of Shares in the DRP.  Shares acquired by the Company on
the Secondary Market or registered in a Secondary Registration for use in the
DRP may be at prices lower or higher than the $10 per Share price which will be
paid for the Initial DRP Shares.

     If the Company acquires shares in the Secondary Market for use in the DRP,
the Company shall use reasonable efforts to acquire Shares for use in the DRP at
the lowest price then reasonably available.  However, the Company does not in
any respect guarantee or warrant that the Shares so acquired and purchased by
the Participant in the DRP will be at the lowest possible price.  Further,
irrespective of the Company's ability to acquire Shares in the Secondary Market
or to complete a Secondary Registration for shares to be used in the DRP, the
Company is in no way obligated to do either, in its sole discretion.

     It is understood that reinvestment of Distributions does not relieve a
Participant of any income tax liability which may be payable on the
Distributions.

     4.  Share Certificates.  The ownership of the Shares purchased through the
         ------------------                                                    
DRP will be in book-entry form only until the Company begins to issue
certificates for all its outstanding Common Stock.

     5.  Reports.  Within 90 days after the end of the Company's fiscal year,
         -------                                                             
the Company will provide each Participant with an individualized report on his
or her investment, including the purchase date(s), purchase price and number of
Shares owned, as well as the dates of distribution and amounts of Distributions
received during the prior fiscal year.  The individualized statement to
Stockholders will include receipts and purchases relating to each Participant's
participation in the DRP including the tax consequences relative thereto.

     6.  Termination by Participant.  A Participant may terminate participation
         --------------------------                                            
in the DRP at any time, without penalty, by delivering to the Company a written
notice.  Prior to listing of the Shares on a stock exchange or Nasdaq, any
transfer of Shares by a Participant to a non-Participant will terminate
participation in the DRP with respect to the transferred Shares.  If a
Participant terminates DRP participation, the Company will provide the
terminating Participant with a certificate evidencing the whole shares in his or
her account and a check for the cash value of any fractional share in such
account.  Upon termination of DRP participation, Distributions will be
distributed to the Stockholder in cash.

     7.  Amendment or Termination of DRP by the Company.  The Directors of the
         ----------------------------------------------                       
Company may by majority vote (including a majority of the Independent Directors)
amend or terminate the DRP for any reason upon 30 days' written notice to the
Participants.

     8.  Liability of the Company.  The Company shall not be liable for any act
         ------------------------                                              
done in good faith, or for any good faith omission to act, including, without
limitation, any claims or liability:  (a) arising out of failure to terminate a
Participant's account upon such Participant's death prior to receipt of notice
in writing of such death; and (b) with respect to the time and the prices at
which Shares are purchased or sold for a Participant's account.  To the extent
that indemnification may apply to liabilities arising under the Securities Act
of 1933, as amended or the securities act of a state, the Company has been
advised that, in the opinion of the Securities and Exchange Commission and
certain state securities commissioners, such indemnification is contrary to
public policy and, therefore, unenforceable.

     9.  Governing Law.  This DRP shall be governed by the laws of the State of
         -------------

additional shares for purchase under the Plan may either through purchases on
the open market, through the Company's share repurchase program and/or
additional registrations of common stock for use in the Plan.  In any case, the
per share purchase price under the Plan for such additionally acquired shares
will equal the then-prevailing market price of the stock as determined by the
Company's Board of Directors, which if the Company's stock is listed shall equal
the price on the applicable stock exchange, Nasdaq or over-the-counter market.

     This Prospectus relates to 1,500,000 shares of Common Stock that have been

THE COMPANY

     The Company, founded in 1997, is a Maryland corporation that owns and
operates income producing real estate, primarily commercial office buildings.
The Company is structured and operated in a manner intended to enable it to
qualify as a real estate investment trust under the Internal Revenue Code of
1986, as amended (the "Code").

THE PLAN

     The Plan provides you with a simple and convenient way to invest your cash
dividends in additional shares of Common Stock.  As a participant in the Plan,
you may purchase shares at a price of $10.00 per share until all 1,500,000
Initial Plan Shares have been purchased.  Thereafter, additional shares for
purchase within the Plan may (but do not have to), be acquired by the Company in
its sole discretion either through purchases on the open market, purchases
pursuant to the Company's share repurchase program and/or additional
registrations of common stock relating to the Plan.  In any case other than
purchase of the Initial Plan Shares, the per share purchase price under the Plan
will equal the then-prevailing market price of the stock, which if the Company's
stock is listed shall equal the price on the applicable stock exchange, Nasdaq
or over-the-counter market.

     You receive free custodial service for the shares you hold through the
Plan.

     Shares for the Plan will be purchased directly from the Company.  Such
shares will be authorized and may be either previously issued or unissued
shares.  Proceeds from the sale of the Plan Shares provide the Company with
funds for general corporate purposes.

ELIGIBILITY

     Holders of record of Common are eligible to participate in the Plan with
respect to any whole number of their shares.  If your shares are held of record
by a broker or nominee and you want to participate in the Plan, you must make
appropriate arrangements with your broker or nominee.

     The Company may refuse participation in the Plan to shareholders residing
in states where shares offered pursuant to the Plan are neither registered under
applicable securities laws nor exempt from registration.

ADMINISTRATION

     As of the date of this Prospectus, the Plan is administered by the Company
or an affiliate of the Company (the "Plan Administrator"), but a different
entity may act as Plan Administrator in the future.  The Plan Administrator will
keep all records of your Plan account and sends statements of your account to
you.  Shares of Common Stock purchased under the Plan are registered in the name
of each participating shareholder.

ENROLLMENT

     You may join the Plan by signing the enrollment form enclosed with this
Prospectus and returning it to the Company.

     Your participation in the Plan will begin with the first dividend payment
after your signed card is received, provided your card is received on or before
ten days prior to the record date established for that dividend.  Record dates
for dividends are ordinarily on or about the 15th day of March, June, September
and December, but may be changed from time to time in the discretion of the
Company's management.  If your enrollment form is received after the record date
for any dividend and before payment of that dividend, that dividend will be paid
to you in cash and reinvestment of your dividends will not begin until the next
dividend payment date.

COSTS

     Participants in the Plan pay no service charges or other fees for purchases
made under the Plan.  All costs of administration of the Plan are paid by the
Company.  However, any interest earned on dividends on shares within the Plan
will be paid to the Company to defray certain costs relating to the Plan.  If
you terminate participation in the Plan or ask that your Plan shares be sold,
you will pay certain charges as explained in "Termination of Participation"
below.  Except as described below, the Company will pay the following
commissions and fees to certain affiliates of the Company in connection with
shares of Common Stock sold to participants under the Plan (expressed as a
percentage of the purchase price proceeds):  (a) a selling commission of 7% (the
"Selling Commission"), all of which may be reallowed to the brokers and dealers
of such shares; (b) a marketing and due diligence fee (the "Due Diligence Fee")
of 2.5%; and (c) an acquisition and advisory fee ("Acquisition and Advisory
Fee") of 3%, which after sale of the Initial Plan Shares will be paid only in
the 

                                      C-5
<PAGE>
 
event that proceeds of the sale of such shares are used to acquire properties.
In Ohio, only the Acquisition and Advisory Fee may be paid in connection with
sales of stock under the Plan.

PURCHASES AND PRICE OF SHARES

     Common Stock dividends will be invested within 30 days after the date on
which Common Stock dividends are paid each quarter (the "Investment Date").
Payment dates for Common Stock dividends are ordinarily on or about the last
calendar day of March, June, September and December, but may be changed from
time to time in the discretion of the Company.

     You become an owner of shares purchased under the Plan as of the Investment
Date.  No shares will be purchased under the Plan at less than their par value
($.01 per share).  Dividends paid on shares held in the Plan (less any required
withholding tax) will be credited to your Plan account.  Dividends are paid on
both full and fractional shares held in your account and are automatically
reinvested.

     Reinvested Distributions.  You may elect dividend reinvestment with respect
     ------------------------                                                   
to any whole number of shares registered in your name on the records of the
Company.  Specify on the enrollment form the number of shares for which you want
dividends reinvested.  Dividends on all shares purchased pursuant to the Plan
will be automatically reinvested.  The number of shares purchased for you as a
participant in the Plan depends on the amount of your dividends on these shares
(less any required withholding tax) and the purchase price of the Common Stock.
Your account will be credited with the number of shares, including fractions
computed to four decimal places, equal to the total amount invested divided by
the purchase price per share.

     Shares of Common Stock for participants will be purchased from the Company
at a price per share of $10 for all of the Initial Plan Shares, and thereafter
(if available) at prices equal to the then-prevailing market price of the stock
as determined by the Company's Board of Directors, which if the Company's stock
is listed shall equal the closing price on the applicable stock exchange, Nasdaq
or over-the-counter market on the trading day immediately prior to the
Investment Date.

     Optional Cash Purchases.  Until determined otherwise by the Company, Plan
     -----------------------                                                  
participants may not make additional cash payments for the purchase of Common
Stock under the Plan.

DIVIDENDS ON SHARES HELD IN PLAN

     Dividends paid on shares held in the Plan (less any required withholding
tax) will be credited to your Plan account.  Dividends are paid on both full and
fractional shares held in your account and are automatically reinvested.

ACCOUNT STATEMENTS

     You will receive a statement of your account within 60 days after each
Investment Date.  The statements will contain a report of all transactions since
the last statement, including information with respect to the number of shares
allocated to your account, the amount of dividends received which are allocable
to you, the amount of Common Stock purchased therewith and the price paid.
These statements are your continuing record of the cost of your purchase and
should be retained for income tax purposes.

CERTIFICATES FOR SHARES

     As of the date of this Prospectus, the Company is not issuing certificates
for shares purchased under the Plan, and your ownership of such shares will be
evidenced on the books of the Company in your account.  The number of shares
purchased will be shown on your statement of account.  This feature permits
ownership of fractional shares, protects against loss, theft or destruction of
stock certificates, and reduces the costs of the Plan.

     After the date the Company begins issuing certificates for the outstanding
shares of its Common Stock, certificates for any number of whole shares credited
to your account will be issued in your name upon your written request to the
Plan Administrator.  Certificates for fractional shares will not be issued.
Should you want your certificates issued in a different name, you must notify
the Plan Administrator in writing and comply with applicable transfer
requirements.  If you wish to sell any whole shares credited to your account
under the Plan, you will have the option of either (i) receiving a certificate
for such whole number of shares, or (ii) requesting that such shares held in
your account be sold, in which case the shares will be sold on the open market
as soon as practicable.  Brokerage commissions on such sales will not be paid by
the Company, and will be deducted from the sales proceeds.  See "Termination of
Participation."  If you wish to pledge shares credited to your account, you must
first have the certificate for those shares issued in your name.

                                      C-6
<PAGE>
 
TERMINATION OF PARTICIPATION

     You may discontinue reinvestment of dividends under the Plan with respect
to all, but not less than all, of your shares (including shares held for your
account in the Plan) at any time by notifying the Plan Administrator in writing
no less than ten days prior to the next record date.  A notice of termination
received by the Plan Administrator after such cutoff date will not be effective
until the next following Investment Date.  Participants who terminate their
participation in the Plan may thereafter rejoin the Plan by notifying the
Company and completing all necessary forms and otherwise as required by the
Company.

     If you notify the Plan Administrator of your termination of participation
in the Plan or if your participation in the Plan is terminated by the Company,
the Company's stock ownership records will be updated to include the number of
whole shares in your Plan account.  For any fractional shares of stock in your
Plan account, the Plan Administrator may either (i) send you a check in payment
for any fractional shares in your account, or (ii) credit your stock ownership
account with any such fractional shares.

     A participant who changes his or her address must promptly notify the Plan
Administrator.  If a participant moves his residence to a state where shares
offered pursuant to the Plan are neither registered nor exempt from registration
under applicable securities laws, the Company may deem the participant to have
terminated participation in the Plan.

AMENDMENT AND TERMINATION OF PLAN

     The Company may, in its sole discretion, amend any aspect of the Plan
without the consent of participants or other stockholders, provided that notice
of any material amendment is sent to participants at least 30 days prior to the
effective date thereof.  The Company may also, in its sole discretion, terminate
the Plan for any reason at any time with ten days prior written notice of such
termination to all participants.  You will be notified if the Plan is terminated
or materially amended.  The Company may also terminate any participant's
participation in the Plan at any time by notice to such participant if continued
participation will, in the opinion of the Board of Directors, jeopardize the
status of the Company as a real estate investment trust under the Code.

VOTING OF SHARES HELD UNDER THE PLAN

     You will be able to vote all shares of Common Stock (including fractional
shares) credited to your account under the Plan at the same time that you vote
the shares registered in your name on the records of the Company.

STOCK DIVIDENDS, STOCK SPLITS AND RIGHTS OFFERINGS

     Your Plan account will be amended to reflect the effect of any stock
dividends, splits, reverse splits or other combinations or recapitalizations by
the Company on shares held in the Plan for you.  If the Company issues to its
shareholders rights to subscribe to additional shares, such rights will be
issued to you based on your total share holdings, including shares held in your
Plan account.

RESPONSIBILITY OF THE PLAN ADMINISTRATOR AND THE COMPANY UNDER THE PLAN

     The Plan Administrator will not be liable for any claim based on an act
done in good faith or a good faith omission to act.  This includes, without
limitation, any claim of liability arising out of failure to terminate a
participant's account upon a participant's death, the prices at which shares are
purchased, the times when purchases are made, or fluctuations in the market
price of Common Stock.

     All notices from the Plan Administrator to a participant will be mailed to
the participant at his last address of record with the Plan Administrator, which
will satisfy the Plan Administrator's duty to give notice.  Participants must
promptly notify the Plan Administrator of any change in address.

     YOU SHOULD RECOGNIZE THAT NEITHER THE COMPANY NOR THE PLAN ADMINISTRATOR
CAN PROVIDE ANY ASSURANCE OF A PROFIT OR PROTECTION AGAINST LOSS ON ANY SHARES
PURCHASED UNDER THE PLAN.

INTERPRETATION AND REGULATION OF THE PLAN

     The Company reserves the right, without notice to participants, to
interpret and regulate the Plan as it deems necessary or desirable in connection
with its operation.  Any such interpretation and regulation shall be conclusive.

                                      C-7

FEDERAL INCOME TAX CONSEQUENCES OF PARTICIPATION IN THE PLAN

     The following discussion summarizes the principal federal income tax
consequences, under current law, of participation in the Plan.  It does not
address all potentially relevant federal income tax matters, including
consequences peculiar to persons subject to special provisions of federal income
tax law (such as tax-exempt organizations, insurance companies, financial
institutions, broker-dealers and foreign persons).  The discussion is based on
various rulings of the Internal Revenue Service regarding several types of
dividend reinvestment plans.  No ruling, however, has been issued or requested
regarding the Plan.  THE FOLLOWING DISCUSSION IS FOR YOUR GENERAL INFORMATION
ONLY, AND YOU MUST CONSULT YOUR OWN TAX ADVISOR TO DETERMINE THE PARTICULAR TAX
CONSEQUENCES (INCLUDING THE EFFECTS OF ANY CHANGES IN LAW) THAT MAY RESULT FROM
YOUR PARTICIPATION IN THE PLAN AND THE DISPOSITION OF ANY SHARES PURCHASED
PURSUANT TO THE PLAN.

     REINVESTED DIVIDENDS.   Stockholders subject to federal income taxation who
elect to participate in the Plan will incur a tax liability for distributions
allocated to them even though they have elected not to receive their dividends
in cash but rather to have their dividends held pursuant to the Plan.
Specifically, participants will be treated as if they received the distribution
from the Company and then applied such distribution to purchase the shares in
the Plan.  A Stockholder designating a distribution for reinvestment will be
taxed on the amount of such distribution as ordinary income to the extent such
distribution is from current or accumulated earnings and profits, unless the
Company has designated all or a portion of the distribution as capital gain
dividend.  In such case, such designated portion of the distribution will be
taxed as a capital gain.  The amount treated as a distribution to you will
constitute a dividend for federal income tax purposes to the same extent as a
cash distribution.

     RECEIPT OF SHARE CERTIFICATES AND CASH.  You will not realize any income if
you receive certificates for whole shares credited to your account under the
Plan.  Any cash received for a fractional share held in your account will be
treated as an amount realized on the sale of the fractional share.  You
therefore will recognize gain or loss equal to any difference between the amount
of cash received for a fractional share and your tax basis in the fractional
share.

INDEMNIFICATION OF DIRECTORS AND OFFICERS OF THE COMPANY

     Directors and officers of the Company shall be indemnified against
liabilities, fines, penalties, and claims imposed upon or asserted against them
for actions in their capacities as directors and/or officers of the Corporation
to the fullest extent permitted under the Delaware General Corporation Law
("DGCL").  This indemnification covers all costs and expenses reasonably
incurred by a director or officer.  In addition, the DGCL and the Company's
Amended and Restated Articles of Incorporation may, under certain circumstances,
eliminate the liability of directors and officers in a shareholder or derivative
proceeding.

     Insofar as indemnification for liabilities arising under the l933 Act may
be permitted to directors, officers, or controlling persons of the Company
pursuant to the foregoing provisions, the Company has been informed that in the
opinion of the Securities and Exchange Commission such indemnification is
against public policy as expressed in the l933 Act and is therefore
unenforceable.  In the event that a claim for indemnification against such
liabilities is asserted by such director or officer, the Company will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the l933 Act and
will be governed by the final adjudication of such issue.

Registration Statement on Form S-11 have been audited by Arthur Andersen LLP,

            SUPPLEMENT NO. 1 DATED APRIL 20, 1998 TO THE PROSPECTUS
                            DATED JANUARY 30, 1998


     This document supplements, and should be read in conjunction with, the
Prospectus of Wells Real Estate Investment Trust, Inc. dated January 30, 1998
(the "Prospectus").  Unless otherwise defined herein, capitalized terms used in
this Supplement shall have the same meanings as set forth in the Prospectus.

     The purpose of this Supplement is to describe the following:

        (i)   The status of the offering of shares of common stock (the
"Shares") in Wells Real Estate Investment Trust, Inc. (the "Company");

        (ii)  Updated Prior Performance Tables included as Exhibit A to the
Prospectus; and

        (iii) Revisions to the "INVESTOR SUITABILITY STANDARDS" and "PLAN OF
DISTRIBUTION" sections of the Prospectus.

STATUS OF THE OFFERING

     Pursuant to the Prospectus, the offering of Shares in the Company commenced
on January 30, 1998.  As of April 17, 1998, the Company had raised a total of
$451,700 in offering proceeds (45,170 Shares), which offering proceeds are being
held in escrow until the Company closes the Minimum Offering in accordance with
the terms of the Prospectus.

PRIOR PERFORMANCE TABLES

     Prior Performance Tables dated as of December 31, 1997 are included as
Exhibit A to this Supplement.

INVESTOR SUITABILITY STANDARDS

     The information contained on page 15 in the "INVESTOR SUITABILITY
STANDARDS" section of the Prospectus is revised as of the date of this
Supplement by the deletion of the fourth full paragraph of that section and the
insertion of the following paragraph in lieu thereof:

          The minimum purchase is 100 Shares ($1,000) (except in certain states
     and as otherwise described below).  No transfers will be permitted of less
     than the minimum required purchase, nor (except in very limited
     circumstances) may an investor transfer, fractionalize or subdivide such
     Shares so as to retain less than such minimum number thereof.  For purposes
     of satisfying the minimum investment requirement for Retirement Plans,
     unless otherwise prohibited by state law, a husband and wife may jointly
     contribute funds from their separate Individual Retirement Accounts
     ("IRAs"), provided that each such contribution is made in increments of at
     least $100.  It should be noted, however, that an investment in the Company
     will not, in itself, create a Retirement Plan for any investor and that in
     order to create a Retirement Plan, an investor must comply with all
     applicable provisions of the Code.  Except in Maine, Minnesota and
     Washington, investors who have satisfied the minimum purchase requirements
     and have purchased units in Prior Wells Public Programs may purchase less
     than the minimum number of Shares set forth above, but in no event less
     than 2.5 Shares ($25).  The minimum purchase for New York investors is 250
     Shares ($2,500); however, the minimum investment for New York IRAs is 100
     Shares ($1,000).  After an investor has purchased the minimum investment,
     any additional investments must be made in increments of at least 2.5
     Shares ($25), except for (i) those made by investors in Maine, who must
     still meet the minimum investment requirement for Maine residents of $1,000
     for IRAs and $2,500 for non-IRAs, (ii) purchases of Shares pursuant to the
     Reinvestment Plan, which may be in lesser amounts, and (iii) the minimum
     purchase requirement for Minnesota investors other than IRAs and Qualified
     Plans of 250 Shares ($2,500), and the minimum purchase for Minnesota IRAs
     and Qualified Plans of 200 Shares ($2,000).
<PAGE>
 
PLAN OF DISTRIBUTION

     The information contained on page 77 in the "PLAN OF DISTRIBUTION" section
of the Prospectus is revised as of the date of this Supplement by the deletion
of the second full paragraph on that page and the insertion of the following
paragraph in lieu thereof:

          In addition, subscribers for Shares may agree with their participating
     broker-dealers and the Dealer Manager to have selling commissions due with
     respect to the purchase of their Shares paid over a seven year period
     pursuant to a deferred commission arrangement (the "Deferred Commission
     Option").  Shareholders electing the Deferred Commission Option will be
     required to pay a total of $9.40 per Share purchased upon subscription,
     rather than $10.00 per Share, with respect to which $0.10 per Share will be
     payable as commissions due upon subscription.  For each of the six years
     following the year of subscription, $0.10 per Share will be paid by the
     Company as deferred commissions with respect to Shares sold pursuant to the
     Deferred Commission Option, which amounts will be deducted from and paid
     out of distributions of Cash Available for Distribution otherwise payable
     to Shareholders holding such Shares. The net proceeds to the Company will
     not be affected by the election of the Deferred Commission Option.  Under
     this arrangement, a Shareholder electing the Deferred Commission Option
     will pay a 1% commission upon subscription, rather than a 7% commission,
     and an amount equal to a 1% commission per year thereafter for the next six
     years will be deducted from and paid by the Company out of Cash Available
     for Distribution otherwise distributable to such Shareholder.  In the event
     that Listing of the Shares occurs at any time prior to the end of the sixth
     year following termination of the Offering, however, the obligation of the
     Company and its Shareholders to make any further payments of commissions
     under the Deferred Commission Option shall terminate, and participating
     broker-dealers will not be entitled to receive any further portion of their
     commissions following Listing of the Company's Shares.

                                   EXHIBIT A

                           PRIOR PERFORMANCE TABLES


     The following Prior Performance Tables (the "Tables") provide information
relating to real estate investment programs sponsored by the Advisor and its
Affiliates ("Wells Prior Public Programs") which have investment objectives
similar to the Company.

     Prospective investors should read these Tables carefully together with the
summary information concerning the Prior Programs as set forth in "PRIOR
PERFORMANCE SUMMARY" elsewhere in this Prospectus.

     INVESTORS IN THE COMPANY WILL NOT OWN ANY INTEREST IN THE PRIOR PROGRAMS
AND SHOULD NOT ASSUME THAT THEY WILL EXPERIENCE RETURNS, IF ANY, COMPARABLE TO
THOSE EXPERIENCED BY INVESTORS IN THE PRIOR PROGRAMS.

     These Tables present actual results of Wells Prior Public Programs that
have investment objectives similar to those of the Company. The Company's
investment objectives are to maximize Net Cash From Operations; to preserve
original Capital Contributions; and to realize capital appreciation over a
period of time. All of the Wells Prior Public Programs have used a substantial
amount of capital and not acquisition indebtedness to acquire their properties.

     The Advisor is responsible for the acquisition, operation, maintenance and
resale of the Wells Prior Public Programs' Properties.  The financial results of
the Wells Prior Public Programs thus provide an indication of the Advisor's
performance of its obligations during the periods covered.  However, general
economic conditions affecting the real estate industry and other factors
contribute significantly to financial results.

     The following tables are included herein:

     TABLE I - Experience in Raising and Investing Funds (As a Percentage of
     Investment)

     TABLE II - Compensation to Sponsor (in Dollars)

     TABLE III - Annual Operating Results of Prior Programs

     TABLE IV (Results of completed programs) and TABLE V (sales or disposals of
property) have been omitted since none of the Prior Programs have sold any of
their properties to date.

     Additional information relating to the acquisition of properties by the
Wells Prior Public Programs is contained in TABLE VI, which is included in the
Registration Statement which the Company has filed with the Securities and
Exchange Commission.  As described above, no Wells Prior Public Program has sold
or disposed of any property held by it.  Copies of any or all information will
be provided to prospective investors at no charge upon request.

     The following are definitions of certain terms used in the Tables:

     "ACQUISITION FEES" shall mean fees and commissions paid by a partnership in
connection with its purchase or development of a property, except development
fees paid to a person not affiliated with the partnership or with a general
partner of the partnership in connection with the actual development of a
project after acquisition of the land by the partnership.

     "ORGANIZATION EXPENSES" shall include legal fees, accounting fees,
securities filing fees, printing and reproduction expenses and fees paid to the
general partners or their affiliates in connection with the planning and
formation of the partnership.

     "UNDERWRITING FEES" shall include selling commissions and wholesaling fees
paid to broker-dealers for services provided by the broker-dealers during the
offering.

                   EXPERIENCE IN RAISING AND INVESTING FUNDS

     This Table provides a summary of the experience of the General Partners and
their Affiliates in Prior Programs for which offerings have been completed since
December 31, 1994.  Information is provided with regard to the manner in which
the proceeds of the offerings have been applied.  Also set forth is information
pertaining to the timing and length of these offerings and the time period over
which the proceeds have been invested in the properties.

     The information contained on page 45 in the "REAL PROPERTY INVESTMENTS"

     Real Estate Fund IX, L.P. ("Wells Fund IX"), Wells Real Estate Fund X, L.P.
     ("Wells Fund X") and Wells Real Estate Fund XI, L.P. ("Wells Fund XI")

     cash flow, resale gain, resale loss and sale proceeds of the Joint Venture

     party offer to purchase all or substantially all of the properties or the

     such

                                       5
<PAGE>
 
     third-party offer, each joint venturer must elect within thirty (30) days
     after receipt of the notice to either (i) purchase the entire interest of
     each venturer that wishes to accept the offer on the same terms and
     conditions as the third-party offer to purchase, or (ii) consent to the
     sale of the properties or last remaining property pursuant to such third-
     party offer.

            On June 24, 1998, Wells OP contributed $1,421,466 in cash to the
     Joint Venture. Said $1,421,466 capital contribution by Wells OP was

     amount of $2,482,810 to purchase a one-story office building located in

     THE LUCENT BUILDING

            Purchase of the Oklahoma City Property. On June 24, 1998, the Joint
            -------------------------------------- 
     Venture acquired a one-story office building containing approximately
     57,186 rentable square feet which was developed and constructed on certain
     real property located in Oklahoma City, Oklahoma (the "Oklahoma City
     Property") by Wells Development pursuant to that certain Agreement for the
     Purchase and Sale of Real Property (the "Contract") dated May 30, 1997
     between Wells Development and the Joint Venture, as amended.

            Wells Development had acquired the Oklahoma City Property on May 30,
     1997, for a purchase price of $695,636, plus $20,869 in real estate
     brokerage commissions and $58,000 in legal fees, title insurance premiums
     and other closing costs. Simultaneously with the acquisition of the
     Oklahoma City Property, Wells Development entered into the Contract with
     the Joint Venture for the sale of the Oklahoma City Property following the
     construction and development thereon of the Lucent Building, as described
     below.

            Pursuant to the terms of the Contract, the Joint Venture made an
     earnest money deposit to Wells Development in the amount of $1,600,000
     consisting of a $650,000 contribution funded by Wells Fund IX and a
     $950,000 contribution funded by Wells Fund X. The earnest money deposit
     paid by the Joint Venture under the Contract was used by Wells Development
     to fund the purchase of the Oklahoma City Property, as described below, and
     to fund the initial costs of the construction and development of the Lucent
     Building. Wells Development also used part of the earnest money deposit to
     acquire an additional strip of land along the northern boundary of the
     Oklahoma City Property to expanded the parking area for the property.

            In addition to the earnest money deposit, Wells Development obtained
     a loan in the amount of $3,900,000 from NationsBank, N.A. to fund the
     construction and development of the Lucent Building (the "Construction
     Loan"). As set forth below, the Construction Loan was paid off upon the
     sale of the Lucent Building to the Joint Venture, and Wells Development
     delivered title to the Joint Venture debt-free at closing.

            The purchase price of the Lucent Building was $5,504,276, which was
     equal to the aggregate cost to Wells Development of the acquisition,
     construction and development of the Lucent Building, including interest and
     other carrying costs, and accordingly, Wells Development made no profit
     from the sale of the Lucent Building to the Joint Venture.

            Description of the Building and the Site. The Oklahoma City Property

     contains a one-story office building with 57,186 net rentable square feet
     and 55,017 net useable square feet with a high tilt-up concrete panel
     exterior and steel framing. Construction of the Lucent Building was
     completed in January 1998. The parking area contains approximately 385
     paved parking spaces.

            The Lucent Building is located at 14400 Hertz Quail Springs Parkway,
     Oklahoma City, Oklahoma. The site consists of approximately 5.3 acres
     located in the Quail Springs Office Park

     in the northwest sector of Oklahoma City. Oklahoma City is located near the
     center of the state and is the State Capitol of Oklahoma. Oklahoma City is
     currently the 42nd largest metropolitan area in the United States. The
     population of the Oklahoma City metropolitan area, which has been
     increasing steadily over the past two decades, is currently in excess of
     1,000,000.

            The site is located approximately ten miles northwest of the central
     business district of Oklahoma City. Access is available from Memorial Road
     on the south and May Avenue on the east with all access streets being four
     lane concrete boulevards with curbs and gutters.

            The Lucent Lease. On May 30, 1997, Wells Development entered into a
            ----------------
     Lease Agreement (the "Lucent Lease") with Lucent Technologies Inc. ("Lucent
     Technologies"), pursuant to which Lucent Technologies agreed to lease all
     of the Lucent Building upon completion of the improvement thereof. At the
     closing of the sale of the Lucent Building to the Joint Venture, Wells
     Development transferred and assigned its interest in the Lucent Lease to
     the Joint Venture.

            Lucent Technologies is a telecommunications company which was spun
     off by AT&T in April of 1996. The company is in the business of designing,
     developing and marketing communications systems and technologies ranging
     from microchips to whole networks and is one of the world's leading
     designers, developers and manufacturers of telecommunications system
     software and products. For the fiscal year ended September 30, 1997, Lucent
     Technologies, a public company traded on the New York Stock Exchange,
     reported net income of approximately $541 million dollars on revenues in
     excess of $26 billion dollars. As of March 31, 1998, Lucent Technologies
     had total assets of in excess of $24 billion dollars and a net worth of in
     excess of $5 billion dollars.

            The initial term of the Lucent Lease is ten years which commenced on
     January 5, 1998 (the "Rental Commencement Date"). Lucent Technologies has
     the option to extend the initial term of the Lucent Lease for two
     additional five year periods. Each extension option must be exercised by
     giving written notice to the landlord at least twelve months prior to the
     expiration date of the then current lease term.

            The annual base rent payable under the Lucent Lease will be $508,383
     payable in equal monthly installments of $42,365 during the first five
     years of the initial lease term, and $594,152 payable in equal monthly
     installments of $49,513 during the second five years of the initial lease
     term. The annual base rent for each extended term under the lease will be
     based upon the fair market rent then being charged by landlords under new
     leases of office space in the metropolitan Oklahoma City market for similar
     space in a building of comparable quality with comparable amenities. The
     Lucent Lease provides that if the parties cannot agree upon the appropriate
     fair market value rate, the rate will be established by real estate
     appraisers.

            Under the Lucent Lease, the Joint Venture, as landlord, is
     responsible for (a) all maintenance, repairs and replacements to the
     structural components of the Lucent Building, including without limitation,
     the roof, exterior walls, bearing walls, support beams, foundations,
     columns, exterior doors, windows, skylights and lateral support, and (b)
     for the portion of the Lucent Lease term ending on the first anniversary of
     the Rental Commencement Date, all maintenance, repairs and replacements to
     the parking area surrounding the Lucent Building including lighting systems
     for the parking area. Under the Lucent Lease, Lucent Technologies is
     responsible for the payment of all property taxes, operating expenses and
     other repair and maintenance work relating to the Lucent Building. Lucent
     Technologies is also required to reimburse the landlord the cost of
     casualty insurance for the property.

            The landlord is responsible for a construction allowance of $857,790
     (calculated at the rate of $15 per rentable square foot), which was funded
     by Wells Development prior to the sale of the Lucent Building to the Joint
     Venture and is included as a portion of the purchase price paid for the
     Lucent Building.

                                       7
<PAGE>
 
            Under the Lucent Lease, Lucent Technologies also has a one-time
     option to terminate the Lucent Lease on the seventh (7th) anniversary of
     the Rental Commencement Date, which is exercisable by written notice to the
     landlord at least twelve (12) months in advance of such 7th anniversary. If
     Lucent Technologies elects to exercise its option to terminate the Lucent
     Lease, Lucent Technologies would be required to pay a termination payment
     intended to compensate the landlord for the present value of funds expended
     as construction allowance and leasing commissions relating to the Lucent
     Lease, amortized over and attributable to the remaining lease term, and a
     rental payment equal to approximately eighteen (18) months of monthly
     rental payments. It is currently anticipated that the termination payment
     required to be paid by Lucent Technologies, in the event it exercises its
     option to terminate the Lucent Lease on the 7th anniversary would be
     approximately $1,338,903 based upon certain assumptions.

            In addition, Lucent Technologies has a one-time option under the
     Lucent Lease to reduce the size of its leased premises by 15,000 square
     feet of useable area effective the last day of the month which is the
     second (2nd) anniversary of the Rental Commencement Date. Such option to
     reduce the leased premises is exercisable by providing at least 180 days
     prior written notice to the landlord and paying the landlord a reduction
     payment equal to $750,000 on the effective date of such reduction.

            There are no assurances that the Joint Venture will be able to
     attract or obtain suitable replacement tenants for the Lucent Building upon
     the expiration of the Lucent Lease or upon the 7th anniversary of the
     Lucent Lease if Lucent Technologies elects to exercise its option to
     terminate the Lucent Lease or for the unleased portion of the Lucent
     Building in the event that Lucent Technologies exercises its option to
     reduce the size of its leased premises.

            In connection with the execution of the Lucent Lease, Wells
     Development entered into agreements with each of two real estate brokers,
     one of which is a firm affiliated with ADEVCO Corporation, the developer of
     the Oklahoma City Property, for the payment of commissions in connection
     with services rendered in procuring the Lucent Lease. The commission
     agreements require Wells Development to pay a total of $330,764 in leasing
     commissions, $110,255 of which is payable to said affiliate of the
     developer. One-half of the leasing commissions were paid by Wells
     Development simultaneously with the closing of its acquisition of the
     Oklahoma City Property, with the remainder of the leasing commissions
     funded by Wells Development prior to the sale of the Lucent Building to the
     Joint Venture. The leasing commissions relating to the Lucent Lease were
     included as a portion of the purchase price paid for the Lucent Building by
     the Joint Venture. Neither broker is affiliated with Wells Development,
     Wells Fund IX, Wells Fund X, Wells Fund XI, the Company or any affiliates
     thereof.

            As of June 30, 1998, the Company held a 4.4% ownership interest in
     each of the properties described below as a result of its ownership
     interest in the Joint Venture:

     THE ABB BUILDING

            Description of the Building and the Site. The Joint Venture owns
            ----------------------------------------  
     certain real property located in Knoxville, Tennessee (the "Knoxville
     Property"). The Knoxville Property contains a three-story steel framed
     office building with a reflective insulated glass and brick exterior
     containing approximately 87,000 gross square feet and 83,885 rentable
     square feet (the "ABB Building"). The Knoxville Property was originally
     purchased by Wells Fund IX on December 13, 1996, and was later contributed
     by Wells Fund IX to the Joint Venture on March 26, 1997. Construction of
     the ABB Building was completed in December 1997. The project site is
     approximately 5.622 acres and contains approximately 297 paved parking
     spaces.

            The ABB Building is located in an office park known as Center Point
     Business Park on Pellissippi Parkway just north of the intersection of
     Interstates 40 and 75, in Knox County, Tennessee approximately 10 miles
     west of the Knoxville central business district. The Pellissippi 
<PAGE>
 
     Parkway and the commercial area along the Interstate 40 and 75 corridor
     have evolved recently from a residential suburb into one of the area's
     fastest growing commercial and retail districts.

            The western portion of Knox County in which the Knoxville Property
     is located has experienced the most growth and development in the Knoxville
     metropolitan area during the past 10 years due primarily to available land
     and services. It is anticipated that the Knoxville metropolitan area will
     continue to grow into a major regional center of trade and tourism due to
     its location at the intersection of Interstates 40 and 75 and the recent
     extension of the Pellissippi Parkway to the Knoxville airport.

            The ABB Lease. On December 10, 1996, Wells Fund IX entered into a
            -------------   
     Lease Agreement (the "ABB Lease") with ABB Flakt, Inc. ("ABB") pursuant to
     which ABB agreed to lease 55,000 rentable square feet of the ABB Building,
     comprising approximately 66% of the rentable square feet of the ABB
     Building. Wells Fund IX assigned its interest in the ABB Lease to the Joint
     Venture on March 26, 1997, simultaneously with the contribution of the
     Knoxville Property to the Joint Venture. The Joint Venture is currently
     negotiating lease terms with a major tenant for lease of the remainder of
     the ABB Building.

            ABB is a Delaware corporation which is principally engaged in the
     business of pollution control engineering and consulting. ABB will use the
     leased area as office space for approximately 220 employees. ABB Asea Brown
     Boveri, Ltd., a Swiss corporation based in Zurich, is the holding company
     of the ABB Asea Brown Boveri Group (the "ABB Group") which is comprised of
     approximately 1,000 companies around the world, including ABB. The ABB
     Group revenue is predominately provided by contracts with utilities and
     independent power producers for the design and engineering, construction,
     manufacture and marketing of products, services and systems in connection
     with the generation, transmission and distribution of electricity. In
     addition, the ABB Group generates a significant portion of its revenues
     from the sale of industrial automation products, systems and services to
     pulp and paper, automotive and other manufacturers. For the fiscal year
     ended December 31, 1997, the ABB Group reported net income of approximately
     $572 million dollars and net worth of approximately $5.2 billion dollars.
     ABB, Inc., the United States parent company of ABB, reported gross revenues
     in 1997 in excess of $4 billion dollars. The ABB Group's total number of
     employees for 1997 was approximately 213,000 worldwide and approximately
     21,000 in the United States.

            As security for ABB's obligations under the Lease, ABB has provided
     to Wells Fund IX (and Wells Fund IX has in turn assigned to the Joint
     Venture), and agreed to maintain in full force and effect at all times
     during the 10 year period from the Rental Commencement Date, an irrevocable
     standby letter of credit in accordance with the terms and conditions set
     forth in the ABB Lease. Each letter of credit issued pursuant to the
     provisions of the ABB Lease is required to be in a form of an irrevocable
     credit, to be issued by an "approved issuer," to name the Joint Venture as
     the beneficiary and to specify that the Joint Venture, as beneficiary, may
     draw against the letter of credit upon the occurrence of a "drawing event."
     "Approved issuer" is defined to require that the letter of credit issuer
     shall have and maintain a Moody's Bank Credit Report Service rating of P-1
     or its equivalent. "Drawing event" is defined to include any failure of ABB
     to pay any installment of rent or other charge or assessment pursuant to
     the terms of the ABB Lease within five days of notice thereof, or any other
     event of default with respect to which the Joint Venture has exercised or
     is exercising its remedies. The letter of credit maintained by ABB is
     required to be in the amount of $4,000,000 until the seventh anniversary of
     the Rental Commencement Date; $3,000,000 from the seventh anniversary of
     the Rental Commencement Date to the eighth anniversary of the Rental
     Commencement Date; $2,000,000 from the eighth anniversary of the Rental
     Commencement Date to the ninth anniversary of the Rental Commencement Date;
     and $1,000,000 from the ninth anniversary of the Rental Commencement Date
     to the tenth anniversary of the Rental Commencement Date. The original
     letter of credit which was delivered by ABB to Wells Fund IX simultaneously
     with the execution of the ABB Lease was issued by Svenska Handelsbanken, a
     Parkway Swedish bank which is the largest bank in the    
 
                                       9
<PAGE>
 
     Nordic region with over $90 billion of assets and a credit rating issued by
     Moody's Bank Credit Report Service of P-1/Aa3, and was issued in the amount
     of $4,000,000 for a one year term. If the Joint Venture draws on the letter
     of credit, the Joint Venture shall apply the proceeds first toward the
     performance of the obligations which ABB has failed to perform under the
     ABB Lease, and the remainder, if any, shall be held by the Joint Venture in
     certain permitted investments as additional security for the performance by
     ABB of the ABB Lease.

            The initial term of the lease is nine years and eleven months which
     commenced on January 1, 1998 (the "Rental Commencement Date").

            The annual base rent payable under the ABB Lease is $646,250 payable
     in equal monthly installments of $53,854 during the first five years of the
     initial lease term, and $728,750 payable in equal monthly installments of
     $60,729 during the last four years and eleven months of the initial lease
     term.

            Under the ABB Lease, ABB is responsible for all expenses, costs and
     disbursements (excluding specific costs billed to specific tenants of the
     building) of every kind and nature relating to or incurred or paid in
     connection with the ownership, management, operation, repair and
     maintenance of the ABB Building, including compensation of employees
     engaged in the operation and management or maintenance of the ABB Building,
     supplies, equipment and materials, utilities, repairs and general
     maintenance, insurance, a management fee in the amount of 4% of the gross
     rental income from the ABB Building, and all taxes and governmental charges
     attributable to the ABB Building or its operations (excluding taxes imposed
     or measured on or by the income of the Joint Venture from operation of the
     ABB Building).

            Under the terms of the ABB Lease, the Joint Venture is responsible
     for a construction allowance of $976,600 (calculated at the rate of $19 per
     useable square foot of the premises). In addition, the Joint Venture has
     agreed to provide ABB on the fifth (5th) anniversary of the Rental
     Commencement Date a redecoration allowance of an amount equal to (i) $5.00
     per square foot of useable area of the premises leased as of the 5th
     anniversary of the Rental Commencement Date which has been leased and
     occupied by ABB for at least three consecutive years ending with such 5th
     anniversary reduced by (ii) $177,000.

            The terms of the ABB Lease provide that ABB has the right of first
     refusal for the lease of any space in the ABB Building not initially leased
     by ABB. In the event that the Joint Venture has secured a potential tenant
     for any of such space, the Joint Venture has agreed to give ABB ten (10)
     business days to exercise its right to add such space to the leased
     premises. The base rent payable and other charges and any allowances shall
     be solely as set forth in the notice to ABB of the proposed terms of the
     lease for the potential tenant of such space. If ABB does not so exercise
     its right of first refusal within such 10 business day period, the Joint
     Venture will have the right to lease the space to the potential tenant,
     except that, after the expiration of any such lease to another party, such
     space will again become subject to ABB's right of first refusal. The ABB
     Lease further provides that the Joint Venture agrees that during the term
     of the ABB Lease, no leases of space with other tenants for any space not
     initially leased by ABB pursuant to the ABB Lease shall have a term in
     excess of three years from the last day of the month in which such third-
     party tenant takes possession of such space.

            ABB has a one-time option to terminate the ABB Lease as of the
     seventh (7th) anniversary of the Rental Commencement Date which is
     exercisable by written notice to the Joint Venture at least twelve (12)
     months in advance of such 7th anniversary. If ABB elects to exercise this
     termination option, ABB is required to pay to the Joint Venture, on or
     before ninety (90) days prior to the 7th anniversary of the Rental
     Commencement Date, a termination payment intended to compensate the Joint
     Venture for the present value of certain sums which the Joint Venture has
     expended in connection with the ABB Lease amortized over and attributable
     to the remaining lease term and a rent payment equal to approximately
     fifteen (15) months of monthly base rental

                                       10

     payments. It is currently anticipated that the termination payment required
     to be paid by ABB in the event it exercises its option to terminate the ABB
     Lease on the 7th anniversary would be approximately $1,818,000 based upon
     certain assumptions.

     THE OHMEDA BUILDING

            Description of the Building and the Site. The Joint Venture owns
            ----------------------------------------- 
     certain real property located in Louisville, Boulder County, Colorado (the
     "Louisville Property"). The Louisville Property contains a two-story office
     building with approximately 106,750 rentable square feet (the "Ohmeda
     Building"). Construction of the Ohmeda Building was completed in January
     1988.

            The Joint Venture purchased the Ohmeda Building on February 13,
     1998, for a purchase price of $10,325,000, plus closing costs of
     approximately $6,644.

            The Ohmeda Building was designed to accommodate the needs of a high-
     technology tenant, and to provide the tenant substantial interior
     flexibility in order to accommodate new product developments, changes in
     electronics manufacturing techniques and the introduction of automated
     material handling systems. The Ohmeda Building is modular re-tan brick with
     flush mortar joints and energy efficient insulated solarban glass set in a
     clear aluminum mullion system. The office area represents approximately 47%
     of the building area, and the non-office area represents approximately 53%.
     The lower level has 17 foot high ceilings and is divided into three areas:
     the production area, the materials and finished goods handling area, and
     the support administration, exercise room and cafeteria area. The cafeteria
     and the exercise room contain a glass curtain wall offering panoramic views
     of the mountains to the west. The upper level on the west side contains
     managerial and financial offices, as well as research and employee amenity
     space.

            The site is approximately five miles southeast of Boulder and
     approximately 17 miles northwest of Denver, situated near Highway 36
     (Centennial Parkway), which is the main thoroughfare between Boulder and
     Denver. The site is a 15 acre tract of land in the Centennial Valley
     Business Park in Louisville, Colorado with scenic views both to and from
     the site. The Louisville Property is situated approximately 100 feet above
     Centennial Parkway with access by a "Z" curve roadway east of the site. All
     of the Ohmeda Building access points, including a glass vestibule entry
     court, are turned away from the strong winds from the west. The parking
     area, which contains approximately 500 parking spaces, is concealed from
     the view of Centennial Parkway and is open to the scenic views of the
     mountains.

            The Ohmeda Lease. The entire 106,750 rentable square feet of the
            ---------------- 
     Ohmeda Building is currently under a net Lease Agreement dated February 26,
     1987, as amended by First Amendment to Lease dated December 3, 1987, and as
     amended by Second Amendment to Lease dated October 20, 1997 (the "Ohmeda
     Lease") with Ohmeda, Inc., a Delaware corporation ("Ohmeda"). The Ohmeda
     Lease currently expires in January 2005, subject to (i) Ohmeda's right to
     effectuate an early termination of the Ohmeda Lease under the terms and
     conditions described below, and (ii) Ohmeda's right to extend the Ohmeda
     Lease for two additional five year periods of time.

            Ohmeda is a medical supply firm based in Boulder, Colorado and is a
     worldwide leader in vascular access and hemodynamic monitoring for hospital
     patients. Ohmeda also has a special products division, which produces
     neonatal and other oxygen care products. Ohmeda recently extended an
     agreement with Hewlett-Packard to include co-marketing and promotion of
     combined Ohmeda/H-P neonatal products.

            Ohmeda was a wholly owned subsidiary of the BOC Group, Inc., a
     Nevada corporation ("BOC"), which is a wholly-owned subsidiary of BOC
     Holdings, whose ultimate parent is The BOC Group PLC, an English
     corporation. On April 3, 1998, BOC sold the division of Ohmeda that
     occupies the Ohmeda Building to Instrumentarium Corporation, a Finnish
     company
<PAGE>
 
     ("Instrumentarium"). The obligations of Ohmeda under the Ohmeda Lease are
     currently guaranteed by both BOC and Instrumentarium. BOC, which is in the
     businesses of gases and related products, vacuum technology and health
     care, reported total consolidated sales of in excess of $2 billion for its
     fiscal year ended September 30, 1997, and a net worth of in excess of $462
     million. Instrumentarium is an international healthcare company
     concentrating on selected fields of medical technology manufacturing,
     marketing and distribution.

            The monthly base rental payable under the Ohmeda Lease is $83,710
     through January 31, 2003; $87,891 from February 1, 2003 through January 31,
     2004; and $92,250 from February 1, 2004 through January 31, 2005. Under the
     Ohmeda Lease, Ohmeda is responsible for all utilities, taxes, insurance and
     other operating costs with respect to the Ohmeda Building during the term
     of the Ohmeda Lease. In addition, Ohmeda shall pay a $21,000 per year
     management fee for maintenance and administrative services of the Ohmeda
     Building. The Joint Venture, as landlord, is responsible for maintenance of
     the roof, exterior and structural walls, foundations, other structural
     members and floor slab, provided that the landlord's obligation to make
     repairs specifically excludes items of cosmetic and routine maintenance
     such as the painting of walls.

            The Ohmeda Lease contains an early termination clause that allows
     Ohmeda the right to terminate the Ohmeda Lease, subject to certain
     conditions, on either January 31, 2001 or January 31, 2002. In order to
     exercise this early termination clause, Ohmeda must give the Joint Venture
     notice on or before 5:00 p.m. MST, January 31, 2000, and said notice must
     identify which early termination date Ohmeda is exercising. If Ohmeda
     exercises its right to terminate on January 31, 2001, then Ohmeda must
     tender $753,388 plus an amount equal to the amount of real property taxes
     estimated to be payable to the landlord in 2002 for the tax year 2001 based
     on the most recent assessment information available on the early
     termination date. If Ohmeda exercises its right to terminate on January 31,
     2002, then Ohmeda must tender $502,259 plus an amount equal to the amount
     of real property taxes estimated to be payable to the landlord in 2003 for
     the tax year 2002 based on the most recent assessment information available
     on the early termination date. At the present time, real property taxes
     relating to this property are approximately $135,500 per year. The payment
     of these amounts by Ohmeda for early termination must be made on or before
     the 180th day prior to the appropriate early termination date. If the
     amount of the real property taxes actually assessed is greater or lesser
     than the amount paid by Ohmeda on the early termination date, then the
     difference shall be adjusted accordingly within thirty (30) days of notice
     of such difference.

            The Ohmeda Lease contains a provision whereby the tenant has the
     option to extend the primary lease term for up to two consecutive five year
     terms at the then current market rental rates.

            In addition, the Ohmeda Lease contains an option to expand the
     premises by an amount of square feet up to a total of 200,000 square feet
     which, if exercised by Ohmeda, will require the Joint Venture to expend
     funds necessary to acquire additional land, if such land is necessary to
     such expansion and available for purchase for said expansion purposes, and
     to construct the expansion space. Ohmeda's option to expand the premises is
     subject to deliverance of at least four (4) months' prior written notice to
     the Joint Venture. During the 4 months subsequent to the notice of Ohmeda's
     intention to expand the premises, Ohmeda and the Joint Venture shall
     negotiate in good faith and enter into an amendment to the Ohmeda Lease for
     the construction and rental of the expansion space. If Ohmeda exercises its
     option to expand the premises, the right to terminate clause described
     above will automatically be canceled, and the primary lease term shall be
     extended for a period of ten (10) years from the date on which a
     certificate of occupancy is issued by the City of Louisville with respect
     to the expansion space. The base rental for the expansion space payable
     under the Ohmeda Lease shall be calculated to generate a rate of return to
     the Joint Venture on its project costs and any retrofit expenses with
     respect to the existing premises incurred by landlord over the new, 10 year
     extended primary lease term, equal to the prime lending rate published by
     Norwest Bank, N.A. on the first day of such extended primary 
<PAGE>
 
     lease term, plus 3.0%, plus full amortization of the tenant finish costs
     with respect to the expansion space and the existing premises. This base
     rental shall be payable through January 31, 2005. The base rental payable
     under the Ohmeda Lease from February 1, 2005 through the remaining balance
     of the new, extended 10 year primary lease term, shall be based on a
     combined rental rate equal to the sum of (i) the base rental payable by
     Ohmeda during lease year number seven for the existing premises, plus (ii)
     the base rent payable by Ohmeda during lease year number seven for the
     expansion space, plus an amount equal to 2% of the combined rental rate.
     Thereafter, the base rent payable for the entire premises shall be the base
     rent payable during the previous lease year plus an amount equal to 2% of
     the base rent payable during such previous lease year.

     THE INTERLOCKEN BUILDING

            Description of the Building and the Site. The Joint Venture owns
            ----------------------------------------  
     certain real property located in Broomfield, Boulder County, Colorado (the
     "Broomfield Property"). The Broomfield Property contains a three-story
     multi-tenant office building with 51,974 rentable square feet (the
     "Interlocken Building"). Construction of the Interlocken Building was
     completed in December 1996.

            The Joint Venture purchased the Interlocken Building on March 20,
     1998, for a purchase price of $8,275,000, plus closing costs of
     approximately $18,000.

            The first floor of the Interlocken Building has multiple tenants and
     contains 15,599 rentable square feet; the second floor is leased to ODS
     Technologies, L.P. ("ODS") and contains 17,146 rentable square feet; and
     the third floor is leased to Transecon, Inc. ("Transecon") and contains
     19,229 rentable square feet.

            The Broomfield Property fronts on Highway 36 (the Boulder-Denver
     Turnpike), which is the main thoroughfare between Boulder and Denver, and
     is located approximately eight miles southeast of Boulder and approximately
     15 miles northwest of Denver. The site is a 5.1 acre tract of land in the
     Interlocken Business Park in Broomfield, Colorado. The Broomfield Property
     contains a parking lot surrounding the entire building with ample parking
     spaces available for tenants and visitors. The Interlocken Business Park is
     a 963-acre business park containing primarily advanced technology and
     research/development oriented companies. The Interlocken Conference Resort,
     which will contain a 430-room hotel, 57,000 square feet of conference space
     and a 27-hole championship golf course, is nearly complete and will border
     the Park's western boundary.

            Description of Leases. As stated above, the entire third floor of
            ---------------------
     the Interlocken Building containing 19,229 rentable square feet (37% of the
     total rentable square feet) is currently under lease to Transecon dated
     June 27, 1996 (the "Transecon Lease"). The Transecon Lease currently
     expires in October 2001, subject to Transecon's right to extend for one
     additional term of five years upon 180 days' notice.

            Transecon is a consumer distributor of environmental friendly
     products, including on-site video and audio production of environmental and
     alternative health videos using state-of-the-art electronics and sound
     stage. Transecon was founded in 1989 and currently employs approximately 60
     people.

            The monthly base rental payable under the Transecon Lease is
     approximately $24,000 for the initial term of the lease, and is calculated
     under the Transecon Lease based upon 18,011 rentable square feet. Under the
     Transecon Lease, Transecon is responsible for its share of utilities,
     taxes, insurance and other operating costs with respect to the Interlocken
     Building during the term of the Transecon Lease. In addition, Transecon has
     a right of first refusal under the lease for any second floor space
     proposed to be leased by the landlord. If Transecon elects to 

                                       13
<PAGE>
 
     extend the lease, the monthly base rental shall be a market rate, but no
     less than $24,000 and no more than $27,700. In accordance with the
     Transecon Lease, Golden Rule, Inc., an affiliate of Transecon, occupies
     6,621 rentable square feet of the third floor. Transecon guarantees the
     entire payment due under the Transecon Lease.

            Transecon also leases 1,510 rentable square feet on the first floor.
     The monthly base rent payable for this space is approximately $2,000
     through January 1999; approximately $2,100 through January 2000;
     approximately $2,150 through January 2001; and approximately $2,200 through
     October 2001.

            The entire second floor of the Interlocken Building containing
     17,146 rentable square feet (33% of total rentable square feet) is
     currently under lease to ODS dated January 14, 1997 (the "ODS Lease"). The
     ODS Lease currently expires in September 2003, subject to ODS's right to
     extend for one additional term of three years upon 180 days' notice.

            ODS provides in-home financial transaction services via telephone
     and television, and it has developed interactive computer-based
     applications for such in-home purchasing. Originally based in Tulsa,
     Oklahoma, ODS has relocated its business to the Interlocken Building.

            The monthly base rental payable under the ODS Lease is approximately
     $22,150 through January 1999; approximately $22,600 through January 2000;
     approximately $23,100 through January 2001; approximately $23,550 through
     January 2002; approximately $24,050 through January 2003; and approximately
     $24,550 through September 2003. The rental payments to be made by the
     tenant under the ODS Lease are also secured by the assignment of a $275,000
     letter of credit which may be drawn upon by the landlord in the event of a
     tenant default under the lease. Under the ODS Lease, ODS is responsible for
     its share of utilities, taxes, insurance and other operating costs with
     respect to the Interlocken Building during the term of the ODS Lease. If
     ODS elects to extend the lease, the monthly base rental shall be a market
     rate as described in the ODS Lease.

            The first floor of the Interlocken Building containing 15,599
     rentable square feet is occupied by several tenants whose leases expire in
     late 2001 or 2002. The aggregate monthly base rental payable under these
     leases for 1998 is approximately $21,250. Each lessee is responsible for
     its share of utilities, taxes, insurance and other operating costs with
     respect to the Interlocken Building during the term of its lease. Most of
     these leases contain a right to extend for one additional five year period
     upon 180 days' notice.

            In the event that Transecon, ODS or any of the first floor tenants
     fail to extend their respective leases, the Joint Venture will be required
     to find one or more new suitable tenants for the Interlocken Building at
     the then prevailing market rental rates.

     PROPERTY MANAGEMENT FEES

            Wells Management Company, Inc. ("Wells Management"), an Affiliate of
     the Company and the Advisor, has been retained to manage and lease all of
     the properties currently owned by the Joint Venture. While the Company and
     Wells Fund XI are authorized to pay aggregate management and leasing fees
     to Wells Management in the amount of 4.5% of gross revenues, Wells Fund IX
     and Wells Fund X are authorized to pay aggregate management and leasing
     fees to Wells Management in the amount of 6% of gross revenues. Since, as
     of June 30, 1998, Wells Fund IX and Wells Fund X held an aggregate 87.8%
     ownership percentage interest in the Joint Venture, while the Company and
     Wells Fund XI held an aggregate 12.2% ownership percentage interest in the
     Joint Venture, 87.8% of the gross revenues of the Joint Venture are subject
     to a 6% property management and leasing fee, while 12.2% of the gross
     revenues of the Joint Venture are subject to a 4.5% property management and
     leasing fee. Wells Management has also received an initial lease fee equal
     to the first month's rent for the ABB Lease and the Lucent Lease. In

                                       14
<PAGE>
 
     addition, Wells Management is entitled to one-time initial lease-up fees
     equal to five percent (5%) of the gross revenues over the initial terms of
     the ABB Lease and the Lucent Lease (not to exceed five years).

To Fund IX and X Associates:

We have audited the accompanying balance sheet of FUND IX AND X ASSOCIATES (a
Georgia Joint Venture) as of December 31, 1997 and the related statements of
loss, partners' capital, and cash flows for the period from inception (March 20,
1997) to December 31, 1997.  These financial statements are the responsibility
of the Joint Venture's management.  Our responsibility is to express an opinion
on these financial statements based on our audit.

We conducted our audit in accordance with generally accepted auditing standards.
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Fund IX and X Associates as of
December 31, 1997 and the results of its operations and its cash flows for the
period from inception (March 20, 1997) to December 31, 1997 in conformity with

                           (A GEORGIA JOINT VENTURE)


                         NOTES TO FINANCIAL STATEMENTS

                      MARCH 31, 1998 AND DECEMBER 31, 1997

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

   ORGANIZATION AND BUSINESS

   On March 20, 1997, Fund IX and X Associates (a joint venture between Wells
   Real Estate Fund IX, L.P. ("Fund IX") and Wells Real Estate Fund X, L.P.
   ("Fund X") was formed to acquire, develop, operate, and sell real properties.
   On March 20, 1997, Fund IX contributed a 5.62-acre tract of real property in
   Knoxville, Tennessee, and improvements thereon, known as the ABB Property, to
   Fund IX and X Associates (the "Joint Venture").  A 83,885-square-foot, three-
   story office building was constructed and commenced operations at the end of
   1997.

   CASH AND CASH EQUIVALENTS

   For the purposes of the statements of cash flows, the Joint Venture considers
   all highly liquid investments purchased with an original maturity of three
   months or less to be cash equivalents.  Cash equivalents include cash and
   short-term investments.  Short-term investments are stated at cost, which
   approximates fair value, and consist of investments in money market accounts.

   USE OF ESTIMATES AND FACTORS AFFECTING THE PARTNERSHIP

   The preparation of financial statements in conformity with generally accepted
   accounting principles requires management to make estimates and assumptions
   that affect the reported amounts of assets and liabilities and disclosure of
   contingent assets and liabilities at the date of the financial statements and
   the reported amounts of revenues and expenses during the reporting period.
   Actual results could differ from those estimates.

   The carrying values of the real estate assets are based on management's
   current intent to hold the real estate assets as long-term investments.  The
   success of the Joint Venture's future operations and the ability to realize
   the investment in its assets will be dependent on the Joint Venture's ability
   to maintain an appropriate level of rental rates, occupancy, and operating
   expenses in future years.  Management believes that the steps it is taking
   will enable the Joint Venture to realize its investment in its assets.

                                      I-6

   INCOME TAXES

   The Joint Venture is not subject to federal or state income taxes, and
   therefore, none have been provided for in the accompanying financial
   statements.  The partners of Fund IX and Fund X are required to include their
   respective shares of profits and losses in their individual income tax
   returns.

   REAL ESTATE ASSETS

   Real estate assets held by the Joint Venture are stated at cost less
   accumulated depreciation.  Major improvements and betterments are capitalized
   when they extend the useful life of the related asset.  All ordinary repairs
   and maintenance are expensed as incurred.

   Management continually monitors events and changes in circumstances which
   could indicate that the carrying amounts of real estate assets may not be
   recoverable. When events or changes in circumstances are present that
   indicate the carrying amounts of real estate assets may not be recoverable,
   management assesses the recoverability of real estate assets under Statement
   of Financial Accounting Standards No. 121, "Accounting for the Impairment of
   Long-Lived Assets and for Long-Lived Assets to Be Disposed of," by
   determining whether the carrying value of such real estate assets will be
   recovered through the future cash flows expected from the use of the asset
   and its eventual disposition. Management believes that there has been no
   impairment in the carrying value of real estate assets held by the Joint
   Venture.

   Depreciation of buildings and land improvements is calculated using the
   straight-line method over 25 years.  Tenant improvements are amortized over
   the life of the related lease or the life of the asset, whichever is shorter.

   REVENUE RECOGNITION

   All leases on real estate assets held by the Joint Venture are classified as
   operating leases, and the related rental income is recognized on a straight-
   line basis over the terms of the respective leases.

   PARTNERS' DISTRIBUTIONS AND ALLOCATIONS OF PROFIT AND LOSS

   Cash available for distribution and allocations of profit and loss to Fund IX
   and Fund X by the Joint Venture are made in accordance with the terms of the
   joint venture agreement.  Generally, these items are allocated in proportion
   to the partners' respective ownership interests.  Cash distributions are
   generally paid by the Joint Venture to Fund IX and Fund X quarterly.

   DEFERRED LEASE ACQUISITION COSTS

   Costs incurred to procure operating leases are capitalized and amortized on a
   straight-line basis over the terms of the related leases.

                                      I-7
<PAGE>
 
2. DEFERRED PROJECT COSTS

   The Wells Real Estate Funds pay a percentage of limited partner contributions
   to Wells Capital, Inc., an affiliate of the Joint Venture, for acquisition
   and advisory services. These payments, as stipulated by the partnership
   agreement, can be up to 5% of the limited partner contributions, subject to
   certain overall limitations contained in the partnership agreement. These
   fees are allocated to specific properties as they are purchased or developed
   and are included in capitalized assets of the Joint Venture.

3. FUTURE MINIMUM RENTAL INCOME

   The future minimum rental income due Fund IX and X Associates under
   noncancelable operating leases at December 31, 1997 is as follows:

          Year ending December 31:

            1998                               $  646,250

                                               $6,814,271
                                               ===========
 
4. COMMITMENTS AND CONTINGENCIES

   Management, after consultation with legal counsel, is not aware of any
   significant litigation or claims against the Joint Venture or its partners.
   In the normal course of business, the Joint Venture or its partners may
   become subject to such litigation or claims.

5. SUBSEQUENT EVENTS (UNAUDITED)

   On February 13, 1998, the Joint Venture acquired a two-story office building,
   the Ohmeda Building, a 106,750-square-foot office building located in
   Louisville, Colorado, for a cash purchase price of $10,325,000 plus
   acquisition expenses of $6,644.  The building is 100% occupied by one tenant
   with an original lease term of ten years that commenced February 1, 1988.

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS



To Wells Real Estate Fund IX, L.P.,
Wells Real Estate Fund X, L.P.,
Wells Real Estate Fund XI, L.P., and
Wells Real Estate Investment Trust, Inc.:

We have audited the accompanying statement of revenues over operating expenses
for the LUCENT BUILDING for the three months ended March 31, 1998.  This
financial statement is the responsibility of management.  Our responsibility is
to express an opinion on this financial statement based on our audit.

We conducted our audit in accordance with generally accepted auditing standards.
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the statement of revenues over operating expenses is
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the statement of revenues
over operating expenses. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation. We believe that our
audit provides a reasonable basis for our opinion.

As described in Note 2, this financial statement excludes certain expenses that
would not be comparable with those resulting from the operations of the Lucent
Building after acquisition by Wells Real Estate Fund IX, L.P., Wells Real Estate
Fund X, L.P., Wells Real Estate Fund XI, L.P., and Wells Real Estate Investment
Trust, Inc.  The accompanying statement of revenues over operating expenses was
prepared for the purpose of complying with the rules and regulations of the
Securities and Exchange Commission and is not intended to be a complete
presentation of the Lucent Building's revenues and expenses.

In our opinion, the statement of revenues over operating expenses presents
fairly, in all material respects, the revenues over operating expenses
(exclusive of expenses described in Note 2) of the Lucent Building for the three
months ended March 31, 1998 in conformity with generally accepted accounting
principles.

<PAGE>

      Description of the Building and Site. The exterior of the Iomega Building
is constructed of concrete tilt-up wall panels approximately 23 feet in height
in the warehouse area with windows along the west and north sides of the
building. The office portion of the Iomega Building on the north side is
constructed of masonry block. Construction of the Iomega Building was completed
in 1989. In 1997, the current tenant, Iomega Corporation, completed construction
of a 16,000 square foot two-level office space addition inside the warehouse
area on the west side of the Iomega Building. The Iomega Building contains an
asphaltic concrete paved parking lot with 286 parking spaces. A railroad spur
provides access to two rail docks on the east side of the Iomega Building.
Access to the Iomega Building is controlled by on-site security guards. The
IX-X-XI-REIT Joint Venture has no current plans to further develop, improve or
renovate the Iomega Building.

      The Iomega Building is located at 2976 South Commerce Way in the Ogden
Commercial and Industrial Park (the "Ogden Commercial Park") in Ogden City,
Utah. The site is an 8.03 acre tract of land located in an area containing
primarily light manufacturing and warehousing buildings. The Iomega Building is
one of the largest and most modern warehouse and office buildings in the Ogden
Commercial Park. Although the Ogden Commercial Park is a well established
industrial park, there are vacant land parcels immediately adjacent to the
Iomega Building on the north, west and south sides.

      The Ogden Commercial Park is located one mile north of Roy City, one mile
northwest of Riverdale City and three miles southwest of the Ogden central
business district. Interstate 15, a major north-south freeway through the state,
and Interstate 84, a major east-west freeway through Weber County, are within
one mile of the site.

      Description of Iomega Lease. The entire Iomega Building is currently under
a net Lease Agreement dated April 9, 1996 (the "Iomega Lease") with Iomega
Corporation ("Iomega"). Wells Fund X assigned its rights under the Iomega Lease
to the IX-X-XI REIT Joint Venture in connection with the contribution of the
Iomega Building on July 1, 1998. The Iomega Lease has a ten year lease term
which commenced on August 1, 1996 and expires on July 31, 2006. The Iomega Lease
contains no extension provisions. Iomega's world headquarters are located within
one mile of the Iomega Building. In the event that Iomega vacates the Iomega
Building at the expiration of its current lease term, the IX-X-XI-REIT Joint
Venture would be required to find one or more new suitable tenants for the
Iomega Building at the then prevailing market rental rates.

      Iomega, a New York Stock Exchange company, is a manufacturer of computer
storage devices used by individuals, businesses, government and educational
institutions, including "Zip" drives and disks, "Jaz" one gigabyte drives and
disks, and tape backup drives and cartridges. Iomega reported total sales of in
excess of $1.7 billion, net income of in excess of $115 million and a net worth
of in excess of $400 million for its fiscal year ended December 31, 1997.

      The monthly base rent payable under the Iomega Lease is $40,000 through
November 12, 1999. Beginning on the 40th and 80th months of the lease term, the
monthly base rent payable under the Iomega Lease will be increased to reflect an
amount equal to 100% of the increase in the Consumer Price Index (as defined in
the Iomega Lease) during the preceding 40 months; provided however, that in no
event shall the base rent be increased with respect to any one year by more than
6% or by less than 3% per annum, compounded annually, on a cumulative basis from
the beginning of the lease term. Under the Iomega Lease, Iomega is responsible
for all utilities, taxes, insurance and other operating costs with respect to
the Iomega Building during the term of the lease. The estimated annual real
estate taxes on the Iomega Building are $63,390. The Joint Venture, as landlord,
is responsible for


                                      -2-
<PAGE>
 
maintenance of the structural soundness of the roof, foundation and exterior
walls of the Iomega Building, reasonable wear and tear and uninsured losses and
damages caused by Iomega excluded.

      Iomega has used all of its $500,000 tenant improvement allowance provided
under the Iomega Lease for the construction of the 16,000 square foot two-level
office space addition described above and the addition of an additional parking
lot outside the south entrance of the Iomega Building.

      Under the terms of the Iomega Lease, the IX-X-XI-REIT Joint Venture is
responsible for carrying and maintaining all risk liability insurance covering
the full replacement cost of the Iomega Building. Iomega is responsible for
carrying and maintaining all risk property insurance covering the full
replacement cost of all property and improvements installed or placed on the
premises by Iomega; worker's compensation insurance with no less than the
minimum limits required by law; employer's liability insurance with such limits
as required by law; and commercial liability insurance, with a minimum limit of
$1,000,000 per occurrence and a minimum umbrella limit of $1,000,000, for a
total minimum combined general liability and umbrella limit of $2,000,000 for
property damage, personal injuries or deaths occurring in or about the premises.
The cost of the insurance paid by the landlord is billed on a monthly basis to
the tenant at a rate of $334. Management believes that the Iomega Building is
adequately insured against loss for property damage, personal injury and deaths
of persons in or about the premises.

The Joint Ventures

      The Fremont Joint Venture. In July 1998, Wells OP entered into a Joint
Venture Agreement known as Wells/Fremont Associates (the "Fremont Joint
Venture") with Wells Development. The purpose of the Fremont Joint Venture is
the acquisition, ownership, leasing, operation, sale and management of real
properties, including, but not limited to, that certain office building
containing 58,424 rentable square feet located in Fremont, Alameda County,
California (the "Fairchild Building").

      Wells Development had previously entered into that certain Agreement for
the Purchase and Sale of Property dated June 8, 1998 with Rose Ventures V, Inc.,
a California corporation, and Thomas G. Haury and Carleen S. Haury to acquire
the Fairchild Building (the "Fairchild Contract"). Prior to the closing of the
Fairchild Building, Wells Development assigned its rights to the Fairchild
Contract to the Fremont Joint Venture, and on July 21, 1998, the Fremont Joint
Venture acquired the Fairchild Building pursuant to the Fairchild Contract.

      The Cort Joint Venture. In July 1998, Wells OP entered into another Joint
Venture Agreement with Wells Development known as Wells/Orange County Associates
(the "Cort Joint Venture") for the purpose of the acquisition, ownership,
leasing, operation, sale and management of real properties, including, but not
limited to, that certain office building containing 52,000 rentable square feet
located in Fountain Valley, Orange County, California (the "Cort Furniture
Building").

      Wells Development had previously entered into that certain Purchase and
Sale Agreement and Joint Escrow Instructions dated June 12, 1998 with Spencer
Fountain Valley Holdings, Inc., a California corporation ("Spencer"), to acquire
the Cort Furniture Building (the "Cort Contract"). Prior to the closing of the
Cort Furniture Building, Wells Development assigned its rights to the Cort
Contract to the Cort Joint Venture, and on July 31, 1998, the Cort Joint Venture
acquired the Cort Furniture Building pursuant to the Cort Contract.

      The Fund X-XI Joint Venture. In July 1998, Wells Fund XI entered into a
Joint Venture Agreement with Wells Fund X known as Fund X and Fund XI Associates
(the "Fund X-XI Joint Venture") for the purpose of the acquisition, ownership,
leasing, operation, sale and management of real properties, and interests in
real properties, including, but not limited to, the acquisition of equity
interests in the Fremont Joint Venture and the Cort Joint Venture (as described
below).


                                      -3-
<PAGE>
 
      Wells OP is acting as the initial Administrative Venturer of both the
Fremont Joint Venture and the Cort Joint Venture and, as such, is responsible
for establishing policies and operating procedures with respect to the business
and affairs of each of these joint ventures. However, approval of each of Wells
OP and ultimately the Fund X-XI Joint Venture will be required for any major
decision or any action which materially affects the Fremont Joint Venture or the
Cort Joint Venture or its real property investments.

Contracts to Acquire Joint Venture Interests

      Acquisition of the Fremont Joint Venture Interest. On July 17, 1998, the
Fund X-XI Joint Venture entered into an Agreement for the Purchase and Sale of
Joint Venture Interest (the "Fremont JV Contract") with Wells Development.
Pursuant to the Fremont JV Contract, the Fund X-XI Joint Venture contracted to
acquire Wells Development's interest in the Fremont Joint Venture (the "Fremont
JV Interest") which, at closing, will result in the Fund X-XI Joint Venture
becoming a joint venture partner with Wells OP in the ownership of the Fairchild
Building. Wells Fund X, Wells XI and Wells Development are all Affiliates of
Wells Capital, Inc. (the "Advisor") and the Company.

      At the time of entering into the Fremont JV Contract, the Fund X-XI Joint
Venture delivered $2,000,000 to Wells Development as an earnest money deposit.
Wells Development contributed the earnest money it received from the Fund X-XI
Joint Venture to the Fremont Joint Venture as its initial capital contribution
of $2,000,000, and Wells OP simultaneously contributed $995,480 to the Fremont
Joint Venture as its initial capital contribution.

      Acquisition of the Cort JV Interest. On July 30, 1998, the Fund X-XI Joint
Venture entered into another Agreement for the Purchase and Sale of Joint
Venture Interest (the "Cort JV Contract") with Wells Development. Pursuant to
the Cort JV Contract, the Fund X-XI Joint Venture contracted to acquire Wells
Development's interest in the Cort Joint Venture (the "Cort JV Interest") which,
at closing, will result in the Fund X-XI Joint Venture becoming a joint venture
partner with Wells OP in the ownership of the Cort Furniture Building.

      At the time of entering into the Cort JV Contract, the Fund X-XI Joint
Venture delivered $1,500,000 to Wells Development as an earnest money deposit.
Wells Development contributed the earnest money it received from the Fund X-XI
Joint Venture to the Cort Joint Venture as its initial capital contribution of
$1,500,000, and Wells OP simultaneously contributed $168,000 to the Cort Joint
Venture as its initial capital contribution.

The Fairchild Building

      Purchase of the Fairchild Building. On July 21, 1998, the Fremont Joint
Venture acquired the Fairchild Building pursuant to the Fairchild Contract for a
purchase price of $8,900,000. The Fremont Joint Venture incurred acquisition
expenses including legal fees, title insurance fees, loan origination fees,
appraisal fees and other closing costs of approximately $60,000. The Fremont
Joint Venture used the $2,995,480 aggregate capital contributions described
above to partially fund the purchase of the Fairchild Building. The Fremont
Joint Venture also obtained a loan in the amount of $5,960,000 from NationsBank,
N.A., the proceeds of which were used to fund the remainder of the cost of the
Fairchild Building (the "Fairchild Loan").

      The Fairchild Loan. The Fairchild Loan matures on July 21, 1999 (the
"Fairchild Maturity Date"), unless the Fremont Joint Venture exercises its
option to extend the Fairchild Maturity Date to January 21, 2000. The interest
rate on the Fairchild Loan is a variable rate per annum equal to the rate
appearing on Telerate Page 3750 as the London InterBank Offered Rate (the "LIBOR
Rate") for a thirty day period plus 220 basis points. Commencing on September 1,
1998, and on the first day of each calendar month thereafter continuing through
and including the first day of the calendar month in which the Fairchild
Maturity Date occurs, the Fremont Joint Venture is required to pay to
NationsBank monthly installments of principal in the amount of $10,498 plus
accrued interest. The Fairchild Loan is secured by a first mortgage against the
Fairchild Building. In addition Leo F. Wells, III and Wells Development,
Affiliates of the Advisor and the Company, are co-guarantors of the Fairchild
Loan.

      Closing of the Fremont JV Interest. Under the Joint Venture Agreement of
the Fremont Joint Venture, cash flow distributions will be paid to Wells OP and
Wells Development in accordance with each such entity's equity interest in the
Fremont Joint Venture based upon each entity's relative capital contribution to
the Fremont Joint Venture. As of July 31, 1998, Wells OP held an approximately
33% equity interest and Wells Development held an approximately 67% equity
interest in the Fremont Joint Venture. As additional offering proceeds are
raised by the Wells REIT, it is anticipated that Wells OP will make additional
capital contributions to the Fremont Joint Venture, which will be utilized to
pay down the Fairchild Loan and will increase Wells OP's relative equity
interest (and decrease Wells Development's relative equity interest) in the
Fremont Joint Venture. Cash flow distributions payable by the Fremont Joint
Venture to Wells Development shall be credited as a purchase price adjustment or
paid to the Fund X-XI Joint Venture at the closing of the acquisition of the
Fremont JV Interest from Wells Development, since Wells Development is
prohibited from making any profit on the transaction during the holding period.

      At such time as sufficient funds have been raised, either in the Fund X-XI
Joint Venture or the Wells REIT, or a combination thereof, to pay off the
Fairchild Loan, the Fund X-XI Joint Venture shall close the acquisition of the
Fremont JV Interest. This closing shall take place on or before July 21, 1999;
however, the Fund X-XI Joint Venture has the right to extend the closing date
for two successive periods of six months if sufficient cash has not been raised
to pay off the Fairchild Loan. At the conclusion of such transaction, the Fund
X-XI Joint Venture will be admitted to the Fremont Joint Venture as a joint
venturer partner in the place of Wells Development. The ultimate equity
percentage interests in the Fremont Joint Venture to be owned by Wells OP and
the Fund X-XI Joint Venture are dependent upon the amount of offering proceeds
which are raised in the future by the Company and by Wells Fund XI and,
accordingly, are indeterminable at this time.

      Description of the Fairchild Building. The Fairchild Building is a
two-story office and manufacturing building with 58,424 rentable square feet.
The Fairchild Building is composed of painted concrete tilt-up wall panels,
plaster walls with a clay tile covered mansard roof on the building's west and
north sides and aluminum framed windows. Construction of the Fairchild Building
was completed in 1985.

      The Fairchild Building is located at 47320 Kato Road on the corner of Kato
Road and Auburn Road in the City of Fremont, California. The site is
approximately 3.05 acres and is located in a commercial area composed of similar
use buildings. The parking area surrounds the Fairchild Building and contains
approximately 184 paved parking spaces.

      An independent appraisal of the Fairchild Building was prepared by CB
Richard Ellis Appraisal Services, a division of CB Commercial, as of June 29,
1998, pursuant to which the market value of the land and the leased fee interest
in the Fairchild Building subject to the Fairchild Lease (described below) was
estimated to be $8,900,000. The value estimate contained in this appraisal was
based upon a number of assumptions, including that the Fairchild Building will
continue operating at a stabilized level with Fairchild occupying 100% of the
rentable areas, and is not necessarily an accurate reflection of the fair market
value of the property. The Fremont Joint Venture also obtained an environmental
report prior to closing evidencing that the environmental condition of the land
encompassing the Fairchild Building was satisfactory.

      Fremont is considered Alameda County's extension of Silicon Valley as it
is home to a large number of high-technology manufacturing and new product
development companies. Fremont, which is the second largest city in Alameda
County and the fourth largest city in the Bay Area with a population of
approximately 190,000, is 25 miles south of Oakland and 15 miles north of San
Jose along Interstate 880. Fremont encompasses approximately 94 square miles and
is the largest source of current and future growth and development in Alameda
County due to its abundance of land relative to other areas and its location on
the fringe of Silicon Valley.

      The Fremont Joint Venture will experience competition for its current
tenant from owners and managers of various other office and manufacturing
buildings located in the immediate area of the Fairchild Building, which


                                      -5-
<PAGE>
 
could adversely affect the Fremont Joint Venture's ability to retain Fairchild
as a tenant, and if necessary in the future, to attract and retain other
tenants.

      The Fairchild Lease. The entire 58,424 rentable square feet of the
Fairchild Building is currently under a net lease agreement dated September 19,
1997 (the "Fairchild Lease") with Fairchild Technologies U.S.A., Inc.
("Fairchild"). Fairchild took early possession of the second floor of the
Fairchild Building on October 1, 1997 at a monthly base rental of $22,456. The
Fairchild Lease commenced on December 1, 1997 (the "Rental Commencement Date")
and expires on November 30, 2004, subject to Fairchild's right to extend the
Fairchild Lease for an additional five-year period. Fairchild must give written
notice of its intention to exercise said option not more than 180 days and not
less than 90 days before the last day of the initial term of the Fairchild
Lease. In the event that Fairchild vacates the Fairchild Building at the
expiration of its current lease term, the Fremont Joint Venture would be
required to find one or more new suitable tenants for the Fairchild Building at
the then prevailing market rental rates.

      Fairchild is a global leader in the design and manufacture of production
equipment for semiconductor and compact disk manufacturing. The semiconductor
equipment group recently unveiled a new line of semiconductor wafer processing
equipment which will provide alternatives to the traditional semiconductor chip
production methods.

      Fairchild is a wholly-owned subsidiary of the Fairchild Corporation, a
Delaware corporation ("Fairchild Corp"). Fairchild Corp is the largest aerospace
fastener and fastening system manufacturer and is one of the largest independent
aerospace parts distributors in the world. Fairchild Corp is a leading supplier
to aircraft manufacturers such as Boeing, Airbus, Lockheed Martin, British
Aerospace and Bombardier and to airlines such as Delta Airlines and U.S.
Airways. The aerospace fastener segment accounted for approximately 51.4% of the
company's net sales and the aerospace parts distribution segment accounted for
approximately 35.9% of the company's net sales in fiscal year 1997. The
obligations of Fairchild under the Fairchild Lease are guaranteed by Fairchild
Corp, which reported total consolidated sales of in excess of $680 Million and a
net worth of in excess of $232 Million for its fiscal year ended June 30, 1997.

      The monthly base rent payable under the Fairchild Lease is $68,128 through
November 30, 1998. On each one-year anniversary of the Rental Commencement Date,
the monthly base rent in effect for the preceding year shall be adjusted upward
by a 3% increase. The monthly base rent during the first year of the extended
term of the Fairchild Lease, if exercised by Fairchild, shall be 95% of the then
fair market rental value of the Fairchild Building subject to the annual 3%
increase adjustments. If Fairchild and the Fremont Joint Venture are unable to
agree upon the fair rental value for the extended lease term, each party shall
select an appraiser and the two appraisers shall establish the rent by
agreement. Under the Fairchild Lease, Fairchild is responsible for all
utilities, taxes, insurance and other operating costs with respect to the
Fairchild Building during the term of the Fairchild Lease. Currently, the annual
real estate taxes for the Fairchild Building are approximately $37,000. The
Fremont Joint Venture, as landlord, is responsible for the maintenance and
repair of the structural elements of the roof, bearing walls and foundation of
the Fairchild Building.

      Under the terms of the Fairchild Lease, Fairchild is required to carry and
maintain, at its own cost and expense, certain types of insurance in form
acceptable to the Fremont Joint Venture, naming the Fremont Joint Venture as an
additional insured. With respect to insurance against loss or damage to the
Fairchild Building, Fairchild is required to name the Fremont Joint Venture as
loss payee under its policy. Among other types of insurance, the Fairchild Lease
requires that Fairchild maintain liability insurance coverage covering the
leased premises and Fairchild's use thereof against claims for personal injury,
death, property damage and product liability, in single limit amounts of not
less than $2,000,000 per occurrence, and an equivalent form of insurance against
loss or damage of the Fairchild Building, including earthquake insurance, in an
amount not less than 100% of the actual replacement value of the building and
improvements thereto. Management believes that the Fairchild Building is
adequately insured against loss for property damage, personal injury and deaths
of persons in or about the premises.

The Cort Furniture Building

      Purchase of the Cort Furniture Building. On July 31, 1998, the Cort Joint
Venture acquired the Cort Furniture Building pursuant to the Cort Contract for a
purchase price of $6,400,000. The Cort Joint Venture incurred acquisition
expenses including legal fees, title insurance fees, loan origination fees,
appraisal fees and other closing costs of approximately $63,000. In addition, at
closing, the Cort Joint Venture paid $85,000 in real estate brokerage
commissions to Collins Commercial and Daum Commercial Real Estate, neither of
which are affiliated in any way with the Company or the Advisor. The Cort Joint
Venture used the $1,668,000 aggregate capital contributions to partially fund
the purchase of the Cort Furniture Building. The Cort Joint Venture also
obtained a loan in the amount of $4,875,000 from NationsBank, N.A., the proceeds
of which were used to fund the remainder of the cost of the Cort Furniture
Building (the "Cort Loan").

      The Cort Loan. The Cort Loan matures on July 31, 1999 (the "Cort Maturity
Date"), unless the Cort Joint Venture exercises its option to extend the Cort
Maturity Date to January 31, 2000. The interest rate on the Cort Loan is a
variable rate per annum equal to the rate appearing on Telerate Page 3750 as the
LIBOR Rate for a thirty day period plus 220 basis points. Commencing on
September 1, 1998, and on the first day of each calendar month thereafter
continuing through and including the first day of the calendar month in which
the Cort Maturity Date occurs, the Cort Joint Venture is required to pay to
Nationsbank monthly installments of principal in the amount of $8,587 plus
accrued interest. The Cort Loan is secured by a first mortgage against the Cort
Furniture Building. Leo F. Wells, III and Wells Development are also
co-guarantors of the Cort Loan.

      Closing of the Cort JV Interest. Under the Joint Venture Agreement of the
Cort Joint Venture, cash flow distributions will be paid to Wells OP and Wells
Development in accordance with each such entity's equity interest in the Cort
Joint Venture based upon each entity's relative capital contribution to the Cort
Joint Venture. As of July 31, 1998, Wells Development held an approximately 90%
equity interest and Wells OP held an approximately 10% equity interest in the
Cort Joint Venture. As additional offering proceeds are raised by the Wells
REIT, it is anticipated that Wells OP will make additional capital contributions
to the Cort Joint Venture, which will be utilized to pay down the Cort Loan and
will increase Wells OP's relative equity interest (and decrease Wells
Development's relative equity interest) in the Cort Joint Venture. Cash flow
distributions payable by the Cort Joint Venture to Wells Development shall be
credited as a purchase price adjustment or paid to the Fund X-XI Joint Venture
at the closing of the acquisition of the Cort JV Interest from Wells
Development, since Wells Development is prohibited from making any profit on the
transaction during the holding period.

      At such time as sufficient funds have been raised, either in the Fund X-XI
Joint Venture or the Company, or a combination thereof, to pay off the Cort Loan
on the Cort Furniture Building, the Fund X-XI Joint Venture shall close the
acquisition of the Cort JV Interest. This closing shall take place on or before
July 31, 1999; however, the Fund X-XI Joint Venture has the right to extend the
closing date for two successive periods of six months if sufficient cash has not
been raised to pay off the Cort Loan. At the conclusion of such transaction, the
Fund X-XI Joint Venture will be admitted to the Cort Joint Venture as a joint
venture partner in the place of Wells Development. The ultimate equity
percentage interests in the Cort Joint Venture to be owned by Wells OP and the
Fund X-XI Joint Venture are dependent upon the amount of offering proceeds which
are raised in the future by the Company and by Wells Fund XI and, accordingly,
are indeterminable at this time.

      Description of the Cort Furniture Building. The Cort Furniture Building is
a single-story office and warehouse building with 52,000 rentable squire feet
comprised of an 18,000 square foot office and open showroom area and a 34,000
square foot warehouse area. The Cort Furniture Building's foundation is shallow
reinforced concrete spread footings under load bearing columns with floor slabs
consisting of four inch thick reinforced concrete slab. The exterior walls of
the Cort Furniture Building are load bearing concrete tilt-wall panels. The roof
framing is composed of one-half inch thick plywood decking supported by glu-lam
beams and wood joyces. The main entrance of the Cort Furniture Building consists
of covered walkways. The site contains approximately 150 paved parking spaces.
Construction of the Cort Furniture Building was completed in 1975.


                                      -7-
<PAGE>
 
      An independent appraisal of the Cort Furniture Building was prepared by
Cushman Wakefield, real estate appraisers and consultants, as of July 1, 1998,
pursuant to which the market value of the land and the leased fee interest in
the Cort Furniture Building subject to the Cort Furniture Lease (described
below) was estimated to be $6,400,000. The value estimate contained in this
appraisal was based upon a number of assumptions, including that the Cort
Furniture Building will continue operating at a stabilized level with Cort
occupying 100% of the rentable areas, and is not necessarily an accurate
reflection of the fair market value of the property. The Cort Joint Venture also
obtained an environmental report prior to closing evidencing that the
environmental condition of the land encompassing the Cort Furniture Building was
satisfactory.

      The Cort Furniture Building is located at 10700 Spencer Street on the
southeast corner of Spencer Avenue and Mt. Langley Street adjacent on the south
side to Interstate 405 (with good freeway exposure) located in the City of
Fountain Valley, Orange County, California. The site consists of two parcels of
land totalling approximately 3.65 acres and is located in an established,
built-out industrial pocket within the southeastern region of the city. The site
is located approximately four miles West of the John Wayne Airport.

      Fountain Valley is considered an established bedroom community which is
characterized by a family-oriented, affluent resident population. The city is
located on the fringe of one of the county's major regional employment centers.
Most development within the immediate area consists of mid-sized warehouse
distribution facilities, garden office buildings, corporate headquarter
facilities, small incubator industrial parks and various retail showroom
buildings. Fountain Valley encompasses approximately 9.75 square miles and is
considered to be in the stable stage of its life cycle with relatively little
vacant land parcels available for development. While the population of Fountain
Valley as of 1997 was approximately 55,000 residents, Orange County had a
population in excess of 2.6 million. Orange County employs about 10% of the
state's workers despite having only about 8% of the state's population.

      The Cort Joint Venture will experience competition for its current tenant
from owners and managers from various other office and warehouse buildings
located in the immediate area of the Cort Furniture Building which could
adversely affect the Cort Joint Venture's ability to retain Cort as a tenant,
and if necessary in the future, to attract and retain other tenants.

      The Cort Furniture Lease. The entire 52,000 rentable square feet of the
Cort Furniture Building is currently under a net lease agreement dated October
25, 1988 (The "Cort Furniture Lease") with Cort Furniture Rental Corporation, a
New York corporation ("Cort"). Cort uses the Cort Furniture Building as its
regional corporate headquarters with an attached clearance showroom and
warehouse storage areas. The Cort Furniture Building was originally developed
for and occupied by Mary Kay Cosmetics as their regional corporate headquarters.
In March 1988, the Cort Furniture Building was leased to Cort. Subsequently,
Cort exercised an option to purchase the property in mid-1988. In October 1988,
Cort sold the property to Spencer and leased back the property for a 15 year
term at an initial lease rate of $0.914 per square foot per month (on a triple
net basis).

      The Cort Furniture Lease commenced on November 1, 1988 (the "Rental
Commencement Date") and contains a lease term of 15 years expiring on October
31, 2003. Cort has an option to extend the Cort Furniture Lease for an
additional five-year period of time. Such option must be exercised by Cort in a
written notice delivered to the Cort Joint Venture at least one year prior to
the expiration of the then current lease term. In the event that Cort vacates
the Cort Furniture Building at the expiration of its current lease term, the
Cort Joint Venture would be required to find one or more suitable tenants for
the Cort Furniture Building at the then prevailing market rental rates.

      Cort is a wholly owned subsidiary of Cort Business Services Corporation, a
New York Stock Exchange Company trading under the symbol CBZ ("Cort Business
Services"). Cort Business Services is the largest and only national provider of
high-quality office and residential rental furniture and related accessories.
Cort Business Services has operations that cover 32 states and the District of
Columbia, including 109 rental showrooms, 72 clearance centers and 72
distribution centers. The obligations of Cort under the Cort Furniture Lease are
guaranteed


                                      -8-
<PAGE>
 
by Cort Business Services, which reported net income of in excess of $22 million
on total consolidated revenue of in excess of $287 million, and reported a net
worth of in excess of $149 million for its fiscal year ended December 31, 1997.

      The monthly base rent payable under the Cort Furniture Lease is $63,247
through April 30, 2001 at which time the monthly base rent will be increased 10%
to $69,574 for the remainder of the lease term. The monthly base rent during the
first year of the extended term shall be 90% of the then fair market rental
value of the Cort Furniture Building, but will be no less than the rent in the
15th year of the Cort Furniture Lease. If Cort and the Cort Joint Venture are
unable to agree upon a fair rental value for the extended lease term, each party
shall select an appraiser and the two appraisers shall provide appraisals on the
Cort Furniture Building. If the appraisal values established are within 10% of
each other, the average of such appraised value shall be the fair market rental
value. If said appraisals are varied by more than 10%, the two appraisers shall
appoint a third appraiser and the middle appraisal of the three shall be the
fair rental value. Under the Cort Furniture lease, Cort is responsible for all
utilities, taxes, insurance and other operating costs with respect to the Cort
Furniture Building during the term of the Cort Furniture Lease. The estimated
annual real estate taxes on the Cort Furniture Building are $38,040. The Cort
Joint Venture, as landlord, is responsible for the maintenance and repair of the
structural portions of the exterior walls and the foundation of the Cort
Furniture Building, but shall not include painting or installing, maintaining or
repairing wall or floor coverings.

      Under the terms of the Cort Furniture Lease, the Cort Joint Venture is
responsible for carrying and maintaining liability insurance covering the leased
premises including claims for personal injury, death, property damage and
product liability, in single limit amounts of not less than $1,000,000. The
insurance against property damage to the Cort Furniture Building shall be in an
amount not less than 100% of the actual replacement value of the building and
improvements thereto. The cost of said insurance is billed on a monthly basis to
the tenant. Cort is required to maintain property insurance for its personal
property on the premises, including all inventory, equipment, fixtures and
tenant improvements that have not become a part of the premises, in an amount
equal to the full replacement value of such personal property. Pursuant to the
terms of the Cort Loan, the Cort Joint Venture is required to carry and maintain
earthquake insurance on the Cort Furniture Building for the full replacement
value of the building. Management believes that the Cort Furniture Building is
adequately insured against loss for property damage, personal injury and deaths
of persons in or about the premises.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To Wells Real Estate Fund XI, L.P. and
Wells Real Estate Investment Trust, Inc.:

We have audited the accompanying statement of revenues over certain operating
expenses for the IOMEGA BUILDING for the year ended December 31, 1997. This
financial statement is the responsibility of management. Our responsibility is
to express an opinion on this financial statement based on our audit.

We conducted our audit in accordance with generally accepted auditing standards.
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the statement of revenues over certain operating
expenses is free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the statement of
revenues over certain operating expenses. An audit also includes assessing the
accounting principles used and significant estimates made by management, as well
as evaluating the overall financial statement presentation. We believe that our
audit provides a reasonable basis for our opinion.

As described in Note 2, this financial statement excludes certain expenses that
would not be comparable with those resulting from the operations of the Iomega
Building after acquisition by Fund IX, X, XI, and REIT Joint Venture (a joint
venture between Wells Real Estate Fund IX, L.P., Wells Real Estate Fund X, L.P.,
Wells Real Estate Fund XI, L.P. and Wells Operating Partnership, L.P.). The
accompanying statement of revenues over certain operating expenses was prepared
for the purpose of complying with the rules and regulations of the Securities
and Exchange Commission and is not intended to be a complete presentation of the
Iomega Building's revenues and expenses.

In our opinion, the statement of revenues over certain operating expenses
presents fairly, in all material respects, the revenues over certain operating
expenses of the Iomega Building for the year ended December 31, 1997 in
conformity with generally accepted accounting principles.

1.    ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

      Description of Real Estate Property Acquired

      On July 1, 1998, Wells Real Estate Fund X, L.P. ("Fund X") contributed a
      single-story warehouse and office building with 108,000 rentable square
      feet (the "Iomega Building") to the Fund IX, Fund X, Fund XI, and REIT
      Joint Venture ("IX-X-XI-REIT Joint Venture") (a Georgia joint venture) as
      a capital contribution. Fund X was credited with making a capital
      contribution to the IX-X-XI-REIT Joint Venture in the amount of
      $5,050,425, which represents the purchase price of $5,025,000 plus
      acquisition expenses of $25,425 originally paid by Fund X for the Iomega
      Building on April 1, 1998. As of August 1, 1998, Fund X had made total
      capital contributions to the IX-X-XI-REIT Joint Venture of $18,410,965 and
      held an equity percentage interest in the IX-X-XI-REIT Joint Venture of
      49.9%; Wells Real Estate Fund IX, L.P. had made total capital
      contributions to the IX-X-XI-REIT Joint Venture of $14,571,686 and held an
      equity percentage interest in the IX-X-XI-REIT Joint Venture of 39.5%;
      Wells Operating Partnership, L.P. had made total capital contributions to
      the IX-X-XI-REIT Joint Venture of $1,421,466 and held an equity percentage
      interest in the IX-X-XI-REIT Joint Venture of 3.9%; and Wells Real Estate
      Fund XI, L.P. had made total capital contributions to the IX-X-XI-REIT
      Joint Venture of $2,482,810 and held an equity percentage interest in the
      IX-X-XI-REIT Joint Venture of 6.7%.

      The building is 100% occupied by one tenant with a ten year lease term
      that expires on July 31, 2006. The monthly base rent payable under the
      lease is $40,000 through November 12, 1999. Beginning on the 40th and 80th
      months of the lease term, the monthly base rent payable under the lease
      will be increased to reflect an amount equal to 100% of the increase in
      the Consumer Price Index (as defined in the lease) during the preceding 40
      months; provided however, that in no event shall the base rent be
      increased with respect to any one year by more than 6% or by less than 3%
      per annum, compounded annually, on a cumulative basis from the beginning
      of the lease term. The lease is a triple net lease, whereby the terms
      require the tenant to reimburse the IX-X-XI-REIT Joint Venture for certain
      operating expenses, as defined in the lease, related to the building.

      Rental Revenues

      Rental income from the lease is recognized on a straight-line basis over
      the life of the lease.

2.    BASIS OF ACCOUNTING

      The accompanying statement of revenues over certain operating expenses is
      presented on the accrual basis. This statement has been prepared in
      accordance with the applicable rules and regulations of the Securities and
      Exchange Commission for real estate properties acquired. Accordingly, the
      statement excludes certain historical expenses, such as depreciation and
      management fees, not comparable to the operations of the Iomega Building
      after acquisition by the IX-X-XI REIT Joint Venture.

                         OVER CERTAIN OPERATING EXPENSES

                      FOR THE YEAR ENDED DECEMBER 31, 1997

                   AND FOR THE SIX MONTHS ENDED JUNE 30, 1998

1.    ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

      Description of Real Estate Property Acquired

      The Wells Operating Partnership, L.P. ("Wells OP"), a Delaware limited
      partnership organized to own and operate properties on behalf of the Wells
      Real Estate Investment Trust, Inc, entered into a Joint Venture Agreement
      known as Wells/Orange County Associates ("Cort Joint Venture") with Wells
      Development Corporation. On July 31, 1998, the Cort Joint Venture acquired
      the Cort Furniture Building, a 52,000-square-foot warehouse and office
      building located in Fountain Valley, California, for a purchase price of
      $6,400,000 plus acquisition expenses of approximately $150,000. The Cort
      Joint Venture used the $1,668,000 aggregate capital contributions
      described below to partially fund the purchase of the Cort Furniture
      Building. The Cort Joint Venture obtained a loan in the amount of
      $4,875,000 from NationsBank, N.A., the proceeds of which were used to fund
      the remainder of the cost of the Cort Furniture Building (the "Cort
      Loan"). The Cort Loan matures on July 31, 1999 (the "Cort Maturity Date"),
      unless the Cort Joint Venture exercises its option to extend the Cort
      Maturity Date to January 31, 2000. The interest rate on the Cort Loan is a
      variable rate per annum equal to the rate appearing on Telerate Page 3750
      as the LIBOR Rate for 30-day period plus 220 basis points.

      The building is 100% occupied by one tenant with a 15-year lease term that
      commenced on November 1, 1988 and expires on October 31, 2003. The monthly
      base rent payable under the lease is $63,247 through April 30, 2001 at
      which time the monthly base rent will be increased 10% to $69,574 for the
      remainder of the lease term. The lease is a triple net lease, whereby the
      terms require the tenant to reimburse the Cort Joint Venture for certain
      operating expenses, as defined in the lease, related to the building.

      Acquisition of the Cort Joint Venture Interest

      Wells Real Estate Fund XI, L.P. ("Wells Fund XI") entered into a Joint
      Venture Agreement with Wells Real Estate Fund X, L.P. ("Wells Fund X")
      known as Fund X and Fund XI Associates ("Fund X-XI Joint Venture") for the
      purpose of the acquisition, ownership, leasing, operation, sale and
      management of real properties, and interests in real properties, including
      but not limited to, the acquisition of equity interests in the Cort Joint
      Venture.


                                      F-7

<PAGE>
 
      On July 30, 1998, the Fund X-XI Joint Venture entered into an Agreement
      for the Purchase and Sale of Joint Venture Interest (the "Cort JV
      Contract") with Wells Development. Pursuant to the Cort JV Contract, the
      Fund X-XI Joint Venture contracted to acquire Wells Development's interest
      in the Cort Joint Venture (the "Cort JV Interest") which, at closing, will
      result in the Fund X-XI Joint Venture becoming a joint venture partner
      with Wells OP in the ownership of the Cort Furniture Building. Wells Fund
      X, Wells OP and Wells Development are all affiliates of Wells Fund XI.

      At the time of entering into the Cort JV Contract, the Fund X-XI Joint
      Venture delivered $1,500,000 to Wells Development as an earnest money
      deposit (the "Cort Earnest Money"). Wells Fund XI contributed $750,000 of
      the Cort Earnest Money as a capital contribution to the Fund X-XI Joint
      Venture and, as of July 31, 1998, held an equity percentage interest in
      the Fund X-XI Joint Venture of 50%; and Wells Fund X contributed $750,000
      of the Cort Earnest Money as a capital contribution to the Fund X-XI Joint
      Venture and, as of July 31, 1998, held an equity percentage interest in
      the Fund X-XI Joint Venture of 50%. Wells Development contributed the Cort
      Earnest Money it received from the Fund X-XI Joint Venture to the Cort
      Joint Venture as its initial capital contribution, and Wells OP
      simultaneously contributed $168,000 to the Cort Joint Venture as its
      initial capital contribution.

      Cash flow distributions allocable by the Cort Joint Venture to Wells
      Development will be credited as a purchase price adjustment or paid to the
      Fund X-XI Joint Venture at the closing of the acquisition of the Cort JV
      Interest from Wells Development since Wells Development is prohibited from
      making any profit on the transaction during the holding period. The Fund
      X-XI Joint Venture will have no property rights in the Cort Building prior
      to closing nor any potential liability on the Cort Loan, which will be
      paid off prior to closing.

      Rental Revenues

      Rental income from the lease is recognized on a straight-line basis over
      the life of the lease.

2.    BASIS OF ACCOUNTING

      The accompanying statement of revenues over certain operating expenses is
      presented on the accrual basis. This statement has been prepared in

      Description of Real Estate Property Acquired

      The Wells Operating Partnership, L.P. ("Wells OP"), a Delaware limited

      Real Estate Investment Trust, Inc., entered into a Joint Venture Agreement
      known as Wells/Fremont Associates ("Fremont Joint Venture") with Wells
      Development Corporation. On July 21, 1998, the Fremont Joint Venture
      acquired the Fairchild Building, a 58,424-square-foot warehouse and office
      building located in Fremont, California, for a purchase price of

      of the cost of the Fairchild Building (the "Fairchild Loan"). The
      Fairchild Loan matures on July 21, 1999 (the "Fairchild Maturity Date"),
      unless the Fremont Joint Venture exercises its option to extend the
      Fairchild Maturity Date to January 21, 2000. The interest rate on the
      Fairchild Loan is a variable rate per annum equal to the rate appearing on
      Telerate Page 3750 as the LIBOR Rate for a 30-day period plus 220 basis
      points.

      The building is 100% occupied by one tenant with a seven-year lease term
      that commenced on December 1, 1997 (with an early possession date of
      October 1, 1997) and expires on November 30, 2004. The monthly base rent
      payable under the lease is $68,128 with a 3% increase on each anniversary
      of the commencement date. The lease is a triple net lease, whereby the
      terms require the tenant to reimburse Wells/Fremont for certain operating
      expenses, as defined in the lease, related to the building. Prior to
      October 1, 1997, the building was unoccupied and all operating expenses
      were paid by the former owner of the Fairchild Building.

      Acquisition of the Fremont Joint Venture Interest

      Wells Real Estate Fund XI, L.P. ("Wells Fund XI") entered into a Joint
      Venture Agreement with Wells Real Estate Fund X, L.P. ("Wells Fund X")
      known as Fund X and Fund XI Associates ("Fund X-XI Joint Venture") for the
      purpose of the acquisition, ownership, leasing, operation, sale and
      management of real properties, and interests in real properties, 


                                      F-11

      including but not limited to, the acquisition of equity interests in the
      Fremont Joint Venture.

      On July 17, 1998, the Fund X-XI Joint Venture entered into an Agreement
      for the Purchase and Sale of Joint Venture Interest (the "Fremont JV
      Contract") with Wells Development. Pursuant to the Fremont JV Contract,
      the Fund X-XI Joint Venture contracted to acquire Wells Development's
      interest in the Fremont Joint Venture (the "Freemont JV Interest") which,
      at closing, will result in the Fund X-XI Joint Venture becoming a joint
      venture partner with Wells OP in the ownership of the Fairchild Building.
      Wells Fund X, Wells OP and Wells Development are all affiliates of Wells
      Fund XI.

      At the time of the entering into the Fremont JV Contract, the Fund X-XI
      Joint Venture delivered $2,000,000 to Wells Development as an earnest
      money deposit (the "Fremont Earnest Money"). Wells Fund XI contributed
      $1,000,000 of the Fremont Earnest Money as a capital contribution to the
      Fund X-XI Joint Venture and, as of July 21, 1998, held an equity
      percentage interest in the Fund X-XI Joint Venture of 50%; and Wells Fund
      X contributed $1,000,000 of the Fremont Earnest Money as a capital
      contribution to the Fund X-XI Joint Venture and, as of July 21, 1998, held
      an equity percentage interest in the Fund X-XI Joint Venture of 50%. Wells
      Development contributed the Fremont Earnest Money it received from the
      Fund X-XI Joint Venture to the Fremont Joint Venture as its initial
      capital contribution, and Wells OP simultaneously contributed $995,480 to
      the Fremont Joint Venture as its initial capital contribution.

      Cash flow distributions allocable by the Fremont Joint Venture to Wells
      Development will be credited as a purchase price adjustment or paid to the
      Fund X-XI Joint Venture at the closing of the acquisition of the Fremont
      JV Interest from Wells Development since Wells Development is prohibited
      from making any profit on the transaction during the holding period. The
      Fund X-XI Joint Venture will have no property rights in the Fairchild
      Building prior to closing nor any potential liability on the Fairchild
      Loan, which will be paid off prior to closing.

      Rental Revenues

      Rental income from the lease is recognized on a straight-line basis over
      the life of the lease.

2.    BASIS OF ACCOUNTING

      The accompanying statement of revenues over certain operating expenses is
      presented on the accrual basis. This statement has been prepared in
      accordance with the applicable rules and regulations of the Securities and
      Exchange Commission for real estate properties acquired. Accordingly, the
      statement excludes certain historical expenses, such as interest,

      Fairchild Building after acquisition by Wells/Fremont.

           SUPPLEMENT NO. 6 DATED JANUARY 15, 1999 TO THE PROSPECTUS
                            DATED JANUARY 30, 1998     

     This document supplements, and should be read in conjunction with, the
Prospectus of Wells Real Estate Investment Trust, Inc. dated January 30, 1998,
as supplemented and amended by Supplement No. 1 dated April 20, 1998, Supplement
No. 2 dated June 30, 1998, Supplement No. 3 dated August 12, 1998, Supplement
No. 4 dated November 1, 1998 and Supplement No. 5 dated December 14, 1998
(collectively, the "Prospectus").  This Supplement No. 6 supersedes Supplement
No. 4 and Supplement No. 5.  Unless otherwise defined herein, capitalized terms
used in this Supplement shall have the same meanings as set forth in the
Prospectus.

     The purpose of this Supplement is to describe the following:

          (1)  The status of the offering of shares of common stock in Wells
Real Estate Investment Trust, Inc. (the "Company");

          (2)  Revisions to the "Investor Suitability Standards" and "Plan of
Distribution" sections of the Prospectus;

          (3)  Revisions to the "Legal Matters" and "Conflicts of Interest -Lack
of Separate Representation" sections of the Prospectus;

          (4)  Contract for an undivided interest in a 7.25 acre tract of land
located in Knox County, Tennessee (the "Associates Property") with Wells
Development Corporation ("Wells Development"), an Affiliate of the Advisor, and
the proposed construction and development of an office building thereon;

          (5)  The acquisition of an office building in Tampa, Hillsborough
County, Florida within the Sunforest Business Park;

          (6)  The status of the ABB Building;

          (7)  The status of the Cort Furniture Building;

          (8)  The status of the Fairchild Building;

          (9)  Revisions to the "Management's Discussion and Analysis of
Financial Condition and Results of Operations" section of the Prospectus; and

          (10) Pro Forma Balance Sheet included as Appendix I.

STATUS OF THE OFFERING

     Pursuant to the Prospectus, the offering of shares in the Company commenced
on January 30, 1998.  The Company commenced operations on June 5, 1998, upon the
acceptance of subscriptions for the minimum offering of $1,250,000 (125,000
shares).  As of January 10, 1999, the Company had raised a total of $32,484,200
in offering proceeds (3,248,420 shares).

INVESTOR SUITABILITY STANDARDS

     The information contained on page 15 in the "Investor Suitability
Standards" section of the Prospectus, as amended in Supplement No. 1 to the
Prospectus, is revised and amended as of the date of this Supplement by the
deletion of the fourth full paragraph of that section and the insertion of the
following paragraph in lieu thereof:

          The minimum purchase is 100 shares ($1,000) (except in certain states
     and as otherwise described below).  No transfers will be permitted of less
     than the minimum required purchase, nor (except in very limited
     circumstances) may an investor transfer, fractionalize or subdivide such
     shares so as to retain less
<PAGE>
 
     than such minimum number thereof.  For purposes of satisfying the minimum
     investment requirement for Retirement Plans, unless otherwise prohibited by
     state law, a husband and wife may jointly contribute funds from their
     separate Individual Retirement Accounts ("IRAs"), provided that each such
     contribution is made in increments of at least $100.  It should be noted,
     however, that an investment in the Company will not, in itself, create a
     Retirement Plan for any investor and that in order to create a Retirement
     Plan, an investor must comply with all applicable provisions of the Code.
     Except in Maine, Minnesota and Washington, investors who have satisfied the
     minimum purchase requirements and have purchased units in Prior Wells
     Public Programs or units or shares in other public real estate programs may
     purchase less than the minimum number of shares set forth above, but in no
     event less than 2.5 shares ($25).  The minimum purchase for New York
     investors is 250 shares ($2,500); however, the minimum investment for New
     York IRAs is 100 shares ($1,000).  After an investor has purchased the
     minimum investment, any additional investments must be made in increments
     of at least 2.5 shares ($25), except for (i) those made by investors in
     Maine, who must still meet the minimum investment requirement for Maine
     residents of $1,000 for IRAs and $2,500 for non-IRAs, (ii) purchases of
     shares pursuant to the Reinvestment Plan or reinvestment plans of other
     public real estate programs, which may be in lesser amounts, and (iii) the
     minimum purchase requirement for Minnesota investors other than IRAs and
     Qualified Plans of 250 shares ($2,500), and the minimum purchase
     requirement for Minnesota IRAs and Qualified Plans of 200 shares ($2,000).

LACK OF SEPARATE REPRESENTATION

     The information contained on page 23 in the "Conflicts of Interest" section
of the Prospectus under the heading "Lack of Separate Representation" shall be
amended by inserting the following paragraph:

          The firm of Hunton & Williams ceased acting as counsel to the Company,
     the Advisor and their Affiliates immediately following the effective date
     of the Prospectus.  Holland & Knight LLP has served as counsel to the
     Company since the effective date of the Prospectus.  Holland & Knight LLP
     also serves as counsel to the Advisor, the Dealer Manager and their
     Affiliates.  There is a possibility that in the future the interests of the
     various parties may become adverse.  In the event that a dispute were to
     arise between the Company, the Advisor, the Dealer Manager or their
     Affiliates, the Advisor may be required to cause the Company to retain
     separate counsel for such matters.

CONTRACT BETWEEN WELLS DEVELOPMENT AND WELLS OPERATING PARTNERSHIP, L.P. FOR
ASSOCIATES PROPERTY

     Wells Operating Partnership, L.P. ("Wells OP"), a Delaware limited
partnership organized to own and operate properties on behalf of the Company,
entered into an Agreement for the Purchase and Sale of Property (the "Purchase
Agreement") with Wells Development dated September 15, 1998 for the purchase of
an undivided interest in the Associates Property.  The purchase price to be paid
by Wells OP for its undivided interest shall be $1,650,000 representing a 55%
undivided interest in the Associates Property.  Simultaneously, Wells
Development entered into another Agreement for the Purchase and Sale of Property
for the remaining undivided interest with Beaver Ruin-ARC Way, Ltd. and Carter
Boulevard, Ltd., both Georgia limited partnerships affiliated with the Advisor
(collectively referred to as "Beaver/Carter").  The purchase price of the
undivided interest to be acquired by Beaver/Carter shall be $1,350,000
representing a 45% undivided interest in the Associates Property.  Beaver/Carter
has paid $1,350,000 to Wells Development as an earnest money deposit pursuant to
its contract, and is scheduled to close on its 45% undivided interest on or
before January 19, 1999.  Wells Development will use the earnest money deposit
received from Beaver/Carter, along with a loan in the amount of $4,500,000 from
First Capital Bank (as described below), to partially fund the purchase and
development of the Associates Property.  It is currently anticipated that Wells
OP will close on its 55% undivided interest at such time as Wells Development
has expended the $1,350,000 earnest money deposit and $4,500,000 in loan
proceeds.  Wells Development shall not make any profit or incur any loss in
connection with this transaction.  At closing, Wells OP shall pay the purchase
price for its 55% undivided interest in cash or execute a promissory note for
any unfunded portion of the purchase price.

     At closing, Wells OP shall deliver to Wells Development a closing
statement, a Tenancy-in-Common Agreement, and such other documents as may be
reasonably required by Wells Development in order to effectuate the transaction.
Wells OP's obligation to close on the undivided interest is conditioned upon the
following events:

                                       2
<PAGE>
 
     .    Wells OP shall have available to it at the date of closing sufficient
          proceeds available for investment in properties to fund the purchase
          price;

     .    all the representations and warranties set forth in the Purchase
          Agreement shall be true and correct in all material respects on the
          date of closing;

     .    the receipt by Wells OP of an acceptable appraisal for the property;

     .    the receipt by Wells OP of evidence reasonably satisfactory to it that
          the property is free of any Hazardous Materials;

     .    the receipt of evidence that Associates Housing Finance, LLC has
          executed an acceptable lease in connection with the Associates
          Property;

     .    the execution of a Tenancy-in-Common Agreement with Beaver/Carter in
          form and substance reasonably satisfactory to Wells OP;

     .    evidence that the transaction contemplated by the Beaver/Carter
          agreement has closed; and

     .    a policy of title insurance insuring Wells OP's undivided interest in
          the Associates Property.

TENANCY-IN-COMMON

     Tenancy-in-Common Agreement.  At or near the date that Wells OP closes the
     ---------------------------                                               
acquisition of its undivided interest in the Associates Property, Wells OP will
enter into a Tenancy-in-Common Agreement with Beaver/Carter or assume the
obligations of Wells Development under a Tenancy-in-Common Agreement with
Beaver/Carter.  This Tenancy-in-Common Agreement will set forth the rights of
the parties with regard to their co-ownership of the Associates Property
including, but not limited to, the contribution of funds for the payment of
expenses required in connection with the ownership and management of the
property.  While the Tenancy-in-Common Agreement to be entered into with
Beaver/Carter has not yet been prepared, it is anticipated that such agreement
may contain a right of first refusal or buy-sell provision which would allow
either party to require the other party to sell its interest in the Associates
Property upon the happening of certain events.  In the event that the Tenancy-
in-Common Agreement does contain such a right of first refusal or buy-sell
provision, the Company may be unable to finance any such buy-out right at the
required time.  Further, in the event that such Tenancy-in-Common Agreement
fails to grant the Company the power to control property decisions, an impasse
could be reached on matters pertaining to the ownership or operation of the
Associates Property, which may have a detrimental impact on the success of this
property.

     Co-Tenancy Risks.  Due to the nature of a co-tenancy interest, it may be
     ----------------                                                        
difficult for the Company to sell its co-tenancy interest in the Associates
Property.  Further, ownership of properties in co-tenancies involves certain
risks not otherwise present, including the possibility that the co-tenant in the
investment might become bankrupt, that the co-tenant may be in a position to
take action contrary to the Company's policies or objectives, or that the co-
tenant may have economic or business interests or goals which are inconsistent
with the business interests and goals of the Company.  It should be noted in
this regard that Beaver/Carter obtained the proceeds used to invest in the
Associates Property from a sale of another property in a transaction intended to
qualify as a tax free like-kind exchange.  Accordingly, Beaver/Carter has a
relatively low tax basis in its interest in the Associates Property and may not
desire to sell the Associates Property at the same time as the Company desires
to sell the Associates Property.

THE ASSOCIATES PROPERTY

     Purchase of the Associates Property.  Wells Development entered into a Real
     -----------------------------------                                        
Estate Option Agreement for Lot 10 dated June 21, 1998 and a Real Estate Option
Agreement for Lot 11 dated April 22, 1998, (collectively, the "Option
Agreement") with The Development Corporation of Knox County, a Tennessee
nonprofit corporation (the "Seller").  The Option Agreement provided Wells
Development the option to purchase the Associates Property for

                                       3
<PAGE>
 
a purchase price of $130,000 per acre.  The Seller is not affiliated with the
Company or its Advisor.  Wells Development exercised the options pursuant to the
Option Agreement and acquired the Associates Property on October 7, 1998 for a
purchase price of $812,500 reflecting a site preparation discount of $130,000.
In connection with the closing of the acquisition of the Associates Property,
Wells Development paid title insurance premiums of $2,400 and other
miscellaneous closing costs of $3,245.

     Wells Development entered into a Development Agreement (as hereinafter
described) for the construction of a one-story office building containing
approximately 71,400 rentable square feet to be erected on the Associates
Property (the "Project").  Wells Development entered into a Lease Agreement (the
"Associates Lease") with Associates Housing Finance, LLC ("Associates") pursuant
to which Associates agreed to lease 50,000 rentable square feet of the Project
upon its completion.

     An independent appraisal of the Associates Property was prepared by CB
Richard Ellis, Inc., real estate appraisers as of September 14, 1998, pursuant
to which the market value of the land and the leased fee interest in the
Associates Property subject to the Associates Lease (described below) was
estimated to be $7,800,000, in cash or terms equivalent to cash.  This value
estimate was based upon a number of assumptions, including that the Project will
be finished in accordance with plans and specifications and that the building
will be operating following completion at a stabilized level with Associates
occupying 50,000 rentable square feet and 94% of the remaining rentable area
occupied by other tenants.  Wells Development also obtained an environmental
report prior to closing evidencing that the environmental condition of the
Associates Property was satisfactory.

     The Associates Loan.  Wells Development obtained a construction loan from
     -------------------                                                      
First Capital Bank in the amount of $4,500,000, the proceeds of which are being
used to fund the development and construction of the Project (the "Associates
Loan").  The Associates Loan matures on November 30, 1999, unless Wells
Development exercises its option to extend the Associates Loan maturity date an
additional 12 months.  The interest rate on the Associates Loan is a variable
rate equal to the six month London Inter Bank Offered Rate, plus 200 basis
points, rounded up to the nearest 1/8%.  Wells Development is required to pay to
First Capital Bank monthly installments of interest only with a final payment of
principal, plus all accrued and unpaid interest due on the maturity date.  The
Associates Loan will be secured by a first priority mortgage against the
Project.  In addition, Leo F. Wells, III (an officer and director of the Company
and the Advisor) and Wells Management Company, Inc., an Affiliate of the
Advisor, will be co-guarantors of the Associates Loan.  At closing, Wells OP
shall assume or take title to the Associates Property subject to the Associates
Loan.

     A nonrefundable loan fee of $22,500 (.5% of the loan amount) has been paid
by Wells Development.  An additional nonrefundable loan extension fee of $11,250
(.25% of the loan amount) will be payable upon acceptance of the 12 month
extension option, if exercised.

     Location of the Associates Property.  The Associates Property is located in
     -----------------------------------                                        
an office park known as Centerpoint Business Park, on Pellissippi Parkway just
north of the intersection of Interstates 40 and 75, in Knox County, Tennessee.
The site is outside the city limits of Knoxville and approximately 10 miles west
of the Knoxville central business district.  Pellissippi Parkway and the
commercial area along the Interstate 40/75 corridor has evolved recently from a
residential suburb into one of the area's fastest growing commercial and retail
districts.  The area has become competitive with the metropolitan Knoxville area
office market due to its growth in office space.

     Knoxville, the county seat of Knox County, Tennessee, is the third largest
city in the State of Tennessee, after Memphis and Nashville, and the largest
city in eastern Tennessee.  Knoxville is located at the intersection of two
major interstate highways, I-40 which extends east to west, and I-75 which
extends north to south.  The Knoxville economy is largely oriented to trade and
manufacturing, due to its location as the geographic center of the eastern
portion of the United States and the wide range of available transportation
resources.  Knoxville's central location and transportation access has also
caused it to emerge as a convention center.  The Knoxville metropolitan
statistical area population in 1990 was 604,812, compared to the 1980 census of
565,970.

     The western portion of Knox County, in which the Associates Property is
located, has experienced the most growth and development in the Knoxville
metropolitan area during the past 12 years due primarily to available land

                                       4
<PAGE>
 
and services.  It is anticipated that the Knoxville metropolitan area will
continue to grow as a major regional center of trade and tourism due to its
location at the intersection of Interstates 40 and 75 and the recent extension
of the Pellissippi Parkway to the Knoxville airport.

     Access to the Associates Property is provided by Pellissippi Parkway, a
limited access thoroughfare traversing southeast to the Knoxville airport, with
an interchange at Interstate 40/75 south of the Associates Property.  Nearby
Kingston Pike also provides east and west traffic flow for the Centerpoint
Business Park, and serves as the major commercial center in the immediate area
with a number of large strip shopping centers, a regional mall, gas stations,
convenience stores, office buildings, restaurants and other various
retail/commercial uses.  The Project will be highly visible from both
Centerpoint Parkway and Pellissippi Parkway, since the building elevation will
be at or above road grade.

      Wells Development will experience competition for tenants from owners and
managers of various other office buildings located in the immediate area of the
Project which would adversely effect Wells Development's ability to attract and
retain tenants.

     Development Agreement.  On September 15, 1998, Wells Development entered
     ---------------------                                                   
into a Development Agreement (the "Development Agreement") with ADEVCO
Corporation, a Georgia corporation (the "Developer"), as the exclusive
development manager to supervise, manage and coordinate the planning, design,
construction and completion of the Project.

     The Developer is an Atlanta based real estate development and management
company formed in 1990 which specializes in the development of office buildings.
The Developer has previously developed or is developing a total of six office
buildings for Affiliates of the Advisor.  In this regard, the Developer entered
into:

     .    a development agreement with Wells Real Estate Fund III, L.P. ("Wells
          Fund III"), a public real estate program previously sponsored by the
          Advisor and its Affiliates, for the development of a two-story office
          building containing approximately 34,300 rentable square feet located
          in Greenville, North Carolina (the "Greenville Project");

     .    a development agreement with Fund IV and Fund V Associates, a joint
          venture between Wells Real Estate Fund IV, L.P., ("Wells Fund IV") and
          Wells Real Estate Fund V, L.P. ("Wells Fund V"), both public real
          estate programs previously sponsored by the Advisor and its
          Affiliates, for the development of a four-story office building
          located in Jacksonville, Florida containing approximately 87,600
          rentable square feet (the "Jacksonville IBM Project");

     .    a development agreement with the Fund VII-VIII Joint Venture, a joint
          venture between Wells Real Estate Fund VII, L.P.("Wells Fund VII"),
          and Wells Real Estate Fund VIII, L.P. ("Wells Fund VIII"), both public
          real estate programs previously sponsored by the Advisor and its
          Affiliates, for the development of a two-story office building
          containing approximately 62,000 rentable square feet located in
          Alachua County, near Gainesville, Florida (the "Gainesville Project");

     .    a development agreement with Fund VI, Fund VII and Fund VIII
          Associates, a joint venture among Wells Real Estate Fund VI, L.P.
          ("Wells Fund VI"), a public real estate program previously sponsored
          by the Advisor and its Affiliates, Wells Fund VII and Wells Fund VIII,
          for the development of a four-story office building containing
          approximately 92,964 rentable square feet located in Jacksonville,
          Florida (the "BellSouth Project");

     .    a development agreement with Fund VIII and Fund IX Associates, a joint
          venture between Wells Fund VIII and Wells Real Estate Fund IX, L.P.
          ("Wells Fund IX"), a public real estate program sponsored by the
          Advisor and its Affiliates, for the development of a four-story office
          building containing approximately 96,750 rentable square feet located
          in Madison, Wisconsin (the "Madison Project"); and

                                       5
<PAGE>
 
     .    a Development Agreement with Wells Fund IX for the development of a
          three-story office building containing approximately 83,885 rentable
          square feet located in Knoxville, Tennessee (the "ABB Building").

     The Greenville Project was completed on schedule, and International

     The President of the Developer is David M. Kraxberger.  Mr. Kraxberger has
been in the real estate business for over 17 years.  From 1984 to 1990, Mr.
Kraxberger served as Senior Vice President of Office Development for The Oxford
Group, Inc., an Atlanta based real estate company with operations in seven
southeastern states.  Mr. Kraxberger holds a Masters Degree in Business
Administration from Pepperdine University in Los Angeles, California, and is a
member of the Urban Land Institute and the National Association of Industrial
Office Parks.  Mr. Kraxberger also holds a Georgia real estate license.
Pursuant to the terms of a Guaranty Agreement, Mr. Kraxberger has personally
guaranteed the performance of the Developer under the Development Agreement.
Mr. Kraxberger has also personally guaranteed the performance of the contractor,
Integra Construction, Inc., under the Construction Contract (as hereinafter
described) pursuant to the terms of a separate Guaranty Agreement.  Neither the
Developer nor Mr. Kraxberger are affiliated with the Advisor or its Affiliates.

     The primary responsibilities of the Developer under the Development
Agreement include:

     .    the supervision, coordination, administration and management of the
          work, activities and performance of the architect under the
          Architect's Agreement (as described below) and the contractor under
          the Construction Contract (as described below);

     .    the implementation of a development budget setting forth an estimate
          of all expenses and costs to be incurred with respect to the planning,
          design, development and construction of the Project;

     .    the review of all applications for disbursement made by or on behalf
          of Wells Development under the Architect's Agreement and the
          Construction Contract;

     .    the supervision and management of tenant build-out at the Project; and

     .    the negotiation of contracts with, supervision of the performance of,
          and review and verification of applications for payment of the fees,
          charges and expenses of such design and engineering professionals,
          consultants and suppliers as the Developer deems necessary for the
          design and construction of the Project in accordance with the
          development budget.

     The Developer will also perform other services typical of development
managers including, but not limited to, arranging for preliminary site plans,
surveys and engineering plans and drawings, overseeing the selection by the
Contractor of major subcontractors and reviewing all applicable building codes,
environmental, zoning and land use laws and other applicable local, state and
federal laws, regulations and ordinances concerning the development, use and
operation of the Project or any portion thereof.  The Developer is required to
advise Wells Development on a weekly basis as to the status of the Project and
submit to Wells Development monthly reports with respect to the progress of
construction, including a breakdown of all costs and expenses under the
development budget.  The Developer is required to obtain prior written approval
from Wells Development before incurring and paying any

                                       6
<PAGE>
 
costs which will result in aggregate expenditures under any one category or line
item in the development budget exceeding the amount budgeted therefor.  If the
Developer determines at any time that the development budget is not compatible
with the then prevailing status of the Project and will not adequately provide
for the completion of the Project, the Developer will prepare and submit to
Wells Development for approval an appropriate revision of the development
budget.

     In discharging its duties and responsibilities under the Development
Agreement, the Developer has full and complete authority and discretion to act
for and on behalf of Wells Development.  The Developer has agreed to indemnify
Wells Development from any and all claims, demands, losses, liabilities,
actions, lawsuits, and other proceedings, judgments and awards, and any costs
and expenses arising out of the negligence, fraud or any willful act or omission
by the Developer.  Wells Development has agreed to indemnify the Developer from
and against any and all claims, demands, losses, liabilities, actions, lawsuits
and other proceedings, judgments and awards, and any costs and expenses arising
out of (1) any actions taken by the Developer within the scope of its duties or
authority, excluding negligence, fraud or willful acts of the Developer, and (2)
the negligence, fraud or any willful act or omission on the part of Wells
Development.

     Wells Development may elect to provide funds to the Developer so that the
Developer can pay Wells Development's obligations with respect to the
construction and development of the Project directly.  All such funds of Wells
Development which may be received by the Developer with respect to the
development or construction of the Project will be deposited in a bank account
approved by Wells Development.  If at any time there are in the bank account
funds of Wells Development temporarily exceeding the immediate cash needs of the
Project, the Developer may invest such excess funds in savings accounts,
certificates of deposit, United States Treasury obligations and commercial paper
as the Developer deems appropriate or as Wells Development may direct, provided
that the form of any such investment is consistent with the Developer's need to
be able to liquidate any such investment to meet the cash needs of the Project.
The Developer shall be reimbursed for all advances, costs and expenses paid for
and on behalf of Wells Development.  The Developer will not be reimbursed,
however, for its own administrative costs or for costs relating to travel and
lodging incurred by its employees and agents.  The Developer may be required to
advance its own funds for the payment of any costs or expenses incurred by or on
behalf of Wells Development in connection with the development of the Project if
there are cost overruns in excess of the contingency contained in the
development budget.

     As compensation for the services to be rendered by the Developer under the
Development Agreement, Wells Development will pay a development fee of $112,500.
The fee will be due and payable ratably (on the basis of the percentage of
construction completed) as the construction and development of the Project is
completed.  Wells Development will also pay the Developer an "Associates Work
Fee" of $112,500.  The Associates Work Fee is for services rendered by the
Developer with respect to the supervision and management of tenant build-out of
the premises leased by Associates pursuant to the Associates Lease.  The fee is
due and payable in one lump sum upon the completion of the construction of the
Project and the tenant improvements under the Associates Lease.

     As of the date of this Supplement No. 6, Wells Development has spent in
excess of $1,350,000 towards the construction of the Project.  It is anticipated
that the aggregate of all costs and expenses to be incurred by Wells Development
with respect to the acquisition of the Property, the planning, design,
development, construction and completion of the Project and the build-out of
tenant improvements under the Associates Lease and tenant improvements for the
premises not leased initially by Associates will total approximately $7,428,090
comprised of the following expenditures:

          Construction Contract                        $2,726,640
          Tenant Improvements - Associates Premises     2,042,000
          Tenant Improvements - Additional Space          380,000
          Land                                            812,500
          Contractor's Bond                                28,000
          Work Fee                                         60,000
          Architectural Fees                              141,300
          Architect's Expenses                             36,000

          Associates Work Fee                             112,500
          Additional site work                            130,000
          Survey and Engineering                           47,050

          Signage                                          12,500
          Marketing                                        25,500
          Contingency                                     199,100
          Construction Interest                           175,000
          Loan Fees                                        25,000
          Legal Fees                                       75,000

The total of all the foregoing expenses anticipated to be incurred by Wells
Development with respect to the Project, exclusive of costs relating to
marketing, closing costs and tenant improvements and leasing commissions for the
premises not leased initially by Associates, will total approximately
$6,205,590.  Under the terms of the Development Agreement, the Developer has
agreed that in the event that the total of all such costs and expenses exceeds
$6,205,590, the amount of fees payable to the Developer shall be reduced by the
amount of any such excess.  Unless the fees otherwise payable to the Developer
are reduced as set forth above, it is estimated that the total sums due and
payable to the Developer under the Development Agreement will be approximately
$225,000.

     In the event the Developer should for any reason cease to manage the
development of the Project, Wells Development would have to locate a suitable
successor development manager.  No assurances can be given as to whether a
suitable successor development manager could be found, or what the contractual
terms or arrangement with any such successor would be.

     Construction Contract.  Wells Development entered into a construction
     ---------------------                                                
contract (the "Construction Contract") on September 10, 1998 with the general
contracting firm of Integra Construction, Inc. (the "Contractor") for the
construction of the Project.  The Contractor is a Georgia corporation based in
Atlanta specializing in commercial, industrial and institutional building.  The
Contractor commenced operations in November 1994.  Its principals were formerly
employed by McDevitt & Street Company, a large general contracting firm which
operates throughout the United States and which has served previously as the
general contractor for properties developed by limited partnerships sponsored by
the Advisor.  The Contractor is presently engaged in the construction of five
projects with a total construction value of in excess of $14,400,000, and since
July 1995, has completed twenty-six projects with a total construction value in
excess of $28,600,000.  The Contractor has served as the general contractor for
the construction of the Gainesville Project, an office building in Gainesville,
Florida which is owned by a joint venture between Wells Fund VII and Wells Fund
VIII, and the ABB Building, an office building in Knoxville, Tennessee which is
owned by a joint venture among Wells Fund IX, Wells Fund X, Wells Fund XI and
Wells OP.  The Contractor is not affiliated with Wells Development or the
Advisor.
    
     The Contractor has begun construction of the Project which will consist of
a one-story steel framed office building with reflective insulated glass and
brick exterior containing approximately 71,400 rentable square feet.  As of
December 31, 1998, the Project was estimated to be 21% complete and the
Contractor has billed Wells Development $599,773. As of January 15, 1999, Wells
Development has paid the full balance of $599,773 to the Contractor. The
Property is currently zoned to permit the intended development and operation of
the Project as a commercial office building and has access to all utilities
necessary for the development and operation of the Project, including water,
electricity, sanitary sewer and telephone.     

     The Construction Contract provides that Wells Development will pay the
Contractor a fixed sum of $2,726,640 for the construction of the Project,
excluding tenant improvements.  It is anticipated that the Construction Contract
will be amended to provide for the construction of the tenant improvements
required pursuant to the Associates Lease at such time as the plans and
specifications are drawn for such improvements and the budget for such
improvements is firmly established.  The Contractor will be responsible for all
costs of labor, materials, construction equipment and machinery necessary for
completion of the Project.  In addition, the Contractor will be required to
secure and pay for any additional business licenses, tap fees and building
permits which may be necessary for construction of the Project.

                                       8
<PAGE>
 
     Wells Development is making monthly progress payments to the Contractor in
an amount of 90% of the portion of the contract price properly allocable to
labor, materials and equipment, less the aggregate of any previous payments made
by Wells Development; provided, however, that when a total of $137,732 has been
withheld as retainage, no further retainage will be withheld from the monthly
progress payments.  As of December 31, 1998, $59,977 has been withheld as
retainage.  When construction is substantially complete and the space is
available for occupancy, Wells Development will make a semi-final payment in the
amount of all of the unpaid balance, except that Wells Development may retain an
amount in accordance with the terms of the Construction Contract which is
necessary to protect its remaining interest until final completion of the
Project.  Wells Development will pay the entire unpaid balance when the Project
has been fully completed in accordance with the terms and conditions of the
Construction Contract.  As a condition of final payment, the Contractor will be
required to execute and deliver a release of all claims and liens against Wells
Development.

     The Contractor will be responsible to Wells Development for the acts or
omissions of its subcontractors and suppliers of materials and of persons either
directly or indirectly employed by them.  The Contractor has agreed to indemnify
Wells Development from and against all liability, claims, damages, losses,
expenses and costs of any kind or description arising out of or in connection
with the performance of the Construction Contract, provided that such liability,
claim, damage, loss or expense is caused in whole or in part by any action or
omission of the Contractor, any subcontractor or materialmen, anyone directly or
indirectly employed by any of them or anyone for whose acts any of them may be
liable.  The Construction Contract also requires the Contractor to obtain and
maintain, until completion of the Project, adequate insurance coverage relating
to the Project, including insurance for workers' compensation, personal injury
and property damage.
 
     The Contractor is required to work expeditiously and diligently to maintain
progress in accordance with the construction schedule and to achieve substantial
completion of the Project within the contract time.  The Contractor is required
to employ all such additional labor, services and supervision, including such
extra shifts and overtime, as may be necessary to maintain progress in
accordance with the construction schedule.  It is anticipated that the Project
will be completed on or before January 1, 2000.  As described below, in the
event the Project is not completed by January 1, 2000, Associates' sole remedy
shall be to terminate its lease with Wells Development.  Wells Development shall
obtain a completion and performance bond in an amount sufficient to complete
construction and development of the Project to reduce the risk of non-
performance and to assure compliance with approved plans and specifications.  In
addition, performance by the Contractor of the Construction Contract has been
personally guaranteed by David B. Blackmore and Drew S. White, founding
principals of the Contractor, as well as David Kraxberger, a principal of the
Developer.

     Architect's Agreement.  Smallwood, Reynolds, Stewart, Stewart & Associates,
     ---------------------                                                      
Inc. (the "Architect") is the architect for the Project pursuant to the
Architect's Agreement entered into with Wells Development.  The Architect, which
was founded in 1979, is based in Atlanta, Georgia, has a staff of over 200
persons, and specializes in programming, planning, architecture, interior
design, landscape architecture and construction administration.  The Architect
has its principal office in Atlanta, Georgia and additional offices in Tampa,
Florida and Singapore, Malaysia.  The Architect has designed a wide variety of
projects, with a total construction cost in excess of $2 billion, including
facilities for corporate office space, educational and athletic facilities,
retail space, manufacturing, warehouse and distribution facilities, hotels and
resorts, correctional institutions, and luxury residential units.  The Architect
has performed architectural services with respect to the Gainesville Project and
the Knoxville Project.  The Architect is not affiliated with Wells Development
or the Advisor.

     The Architect's basic services under the Architect's Agreement include the
schematic design phase, the design development phase, the construction documents
phase and the construction phase.  During the schematic design phase, the
Architect prepares schematic design documents consisting of drawings and other
documents illustrating the scale and relationship of Project components.  The
Architect has completed the schematic design phase, and has been paid a fee of
$21,195 for such services.  During the design development phase, the Architect
prepares design development documents consisting of drawings and other documents
to fix and describe the size and character of the entire Project as to
architectural, structural, mechanical, plumbing and fire protection and
electrical systems, materials and such other elements as may be appropriate.
The Architect has completed the design development stage, and has been paid
$42,390 for these services.  During the construction documents phase, the
Architect prepares construction documents consisting of drawings and
specifications setting forth in detail the

                                       9
<PAGE>
 
requirements for the construction of the Project.  The Architect has completed
approximately 95% of the construction documents phase, and has been paid $63,585
for these services.  During the construction phase, the Architect is to provide
administration of the Construction Contract and advise and consult with the
Developer and Wells Development concerning various matters relating to the
construction of the Project.  The Architect is required to visit the Project
site at intervals appropriate to the stage of construction and to become
generally familiar with the progress and quality of the work and to determine
if, in general, the work is proceeding in accordance with the contract schedule.
The Architect is required to keep Wells Development informed of the progress and
quality of the work.  The Architect is also required to determine the amounts
owing to the Contractor based on observations of the site and evaluations of the
Contractor's application for payment and shall issue certificates for payment in
amounts determined in accordance with the Construction Contract described above.
The Architect will also conduct inspections to determine the date of completion
of the Project and shall issue a final certificate for payment.  The Architect
will be paid $14,130 for its services performed during the construction phase.

     The total amount of fees payable to the Architect under the Architect's
Agreement is $141,300.  Payments are being paid to the Architect on a monthly
basis in proportion to the services performed within each phase of service.  In
addition, the Architect and its employees and consultants are reimbursed for
expenses including, but not limited to, transportation in connection with the
Project, living expenses in connection with out-of-town travel, long distance
communications and fees paid for securing approval of authorities having
jurisdiction over the Project.  It is estimated that the total reimbursable
expenses in connection with the development of the Project will be approximately
$36,000.

     Associates Lease.  On September 10, 1998, Wells Development entered into a
     ----------------                                                          
Lease Agreement (the "Associates Lease") with Associates Housing Finance, LLC
("Associates") pursuant to which Associates agreed to lease 50,000 rentable
square feet of the Project, comprising approximately 70% of the Project.

     Associates is a wholly owned subsidiary of Associates First Capital
Corporation ("First Capital"), a Delaware corporation which was recently spun
off by Ford Motor Company.  First Capital is a leading diversified consumer and
commercial finance company which provides finance, leasing and related services
to individual consumers and businesses in the United States and internationally.
First Capital reported net income for the year ended December 31, 1997 of over
$1 billion on gross revenues of over $8 billion and a net worth of over $6
billion.  First Capital has guaranteed $6,206,952 of the Associates Lease.  This
guaranteed amount declines on a monthly basis over the lease term provided there
is no continuing default under the Associates Lease.

     First Capital divides its activities into consumer finance and commercial
finance.  First Capital's consumer finance operations provide a variety of
consumer financing products and services, including home equity lending,
personal lending, retail sales finance and credit cards.  The commercial finance
operations provide retail financing, leasing and wholesale financing for heavy-
duty and medium-duty trucks and truck trailers, construction, material handling
and other industrial and communications equipment, manufactured housing,
recreational vehicle, auto fleet leasing and other commercial products and
services.

     Associates is First Capital's subsidiary engaged in the financing of
manufactured housing, and is the third largest provider of such services in the
United States.  Associates purchases manufactured housing retail installment
contracts originated by retail dealers, originates and services direct loans to
purchasers, and provides wholesale financing to approved manufactured housing
dealers.  Associates also provides commercial business loans to certain
manufactured housing dealers to provide capital to build new retail sales
centers, update existing facilities or expand into community park sales.

     The initial term of the Associates Lease will be eighty-four months to
commence on the earlier of (1) the date which is thirty (30) days after
substantial completion of the building, or (2) the date upon which tenant takes
possession and occupies any portion of the premises for business purposes.
Associates has the option to extend the initial term of the Associates Lease for
two successive five year periods.  Each extension option must be exercised no
less than nine months prior to the expiration of the then current lease term.

     The annual base rent payable under the Associates Lease will be $600,000
($12.00 per square foot) payable in equal monthly installments of $50,000 during
the first twenty-eight months of the lease term; $625,000 ($12.50

                                       10
<PAGE>
 
per square foot) payable in equal monthly installments of $52,083 during the
next twenty-eight months of the lease term; and $650,000 ($13.00 per square
foot) payable in equal monthly installments of $54,167 during the last twenty-
eight months of the lease term.  The annual base rent for each extended term
under the Associates Lease will be the "market rate" for the period covered by
the extended term.  The term "market rate" is defined in the Associates Lease as
the annual effective rental rate per square foot of rentable floor area then
being charged by landlords under new leases of office space in the metropolitan
Knoxville, Tennessee market for similar space in a building of comparable
quality and with comparable parking and other amenities.  The Associates Lease
provides that if the parties cannot agree on the appropriate market rate, the
market rate shall be established by real estate appraisers.

     In addition to the base rent, Associates is required to pay additional rent
equal to its share of all "operating expenses" during the lease term.
"Operating expenses" is defined to include all expenses, costs and disbursements
(excluding specific costs billed to specific tenants of the building) of every
kind and nature, relating to or incurred or paid in connection with the
ownership, management, operation, repair and maintenance of the Project.
"Operating expenses" include compensation of employees engaged in the operation,
management or maintenance of the Project, supplies, equipment and materials,
utilities, repairs and general maintenance, insurance, a management fee in the
amount of 3.5% of the gross rental income from the Project, and all taxes and
governmental charges attributable to the Project or its operation (excluding
taxes imposed or measured on or by the income of Wells Development from the
operation of the Project).

     Under the terms of the Associates Lease, Wells Development is responsible
for a construction allowance of $1,500,000 (calculated at the rate of $30 per
usable square foot of the premises).  The Associates Lease also provides that so
long as Associates shall occupy 50% or more of the rentable floor area of the
building, Associates shall have the right to design and designate the location
of one monument-type sign naming the building and Wells Development will pay
$7,500 of the cost associated with purchasing and installing such sign.

     The terms of the Associates Lease provide that Associates has a right of
first refusal for the lease of any space in the building not initially leased by
Associates.  In the event that Wells Development has secured a potential tenant
for any of such space, Wells Development has agreed to give Associates 10
business days to exercise its right to add such space to the leased premises.
In the event that Associates exercises its right of first refusal, the lease of
the additional space will be subject to all the terms and conditions of the
Associates Lease, including the base rental which shall be based upon the number
of square feet of rentable area added to the premises.  If Associates does not
so exercise its right of first refusal within such 10 business day period, Wells
Development will have the right to lease the space to the potential tenant and
Associates shall have no further rights relating to the additional space.

     The Associates Lease provides that Wells Development is required to cause
the Project to be substantially completed as soon as practicable under the
circumstances, with a goal of achieving substantial completion on or before
January 1, 2000 (subject to force majeure and any delays caused by Associates).
If substantial completion has not occurred on or before January 1, 2000,
Associates' sole right and remedy shall be to terminate the Associates Lease
upon 10 days written notice to Wells Development; provided substantial
completion does not occur during such 10 day period.

     Property Management Fees.  Following construction and completion of the
     ------------------------                                               
Project, property management and leasing services will be performed by Wells
Management Company, Inc. (the "Property Manager"), an Affiliate of the Advisor.
As compensation for its services, the Property Manager will receive fees equal
to 4.5% of the gross revenues for property management services and leasing
services with respect to the Project.  In addition, the Property Manager will
receive a one-time initial lease-up fee relating to the Associates Lease equal
to the first month's rent plus 5% of the gross revenues over the initial term of
the Associates Lease.  In addition, the Property Manager may also receive
initial lease-up fees relating to the lease-up of space not initially leased by
Associates, as provided in the Prospectus.

     Lease-Up Risk.  As set forth above, Associates has agreed to lease
     -------------                                                     
approximately 70% of the Project.  However, since Wells Development has not yet
obtained any leases for the remaining approximately 30% of office space at the
Project, Wells Development will be subject to the normal lease-up risks of a new
commercial office

                                       11
<PAGE>
 
building with respect to the unleased portion of the Project.  No assurances can
be given that Wells Development will be able to attract or obtain suitable
tenants for the remaining approximately 30% of space at the Project or that it

leased by Associates upon the expiration of its lease.

THE PWC BUILDING

     Purchase of the PWC Building.  On December 31, 1998, Wells OP acquired a
     ----------------------------                                            
four-story office building containing approximately 130,090 rentable square feet
(the "PWC Building") which was recently developed and constructed on an
approximately 9 acre tract of real property located in Tampa, Hillsborough
County, Florida.  Wells OP purchased the PWC Building from Carter Sunforest,
L.P. (the "Seller"), a Georgia limited partnership, pursuant to the terms of the
Amended and Restated Purchase Agreement dated December 4, 1998 (the "Purchase
Agreement") between the Seller and Wells OP.  The total purchase price for the
PWC Building pursuant to the Purchase Agreement was $21,127,854.  Wells OP paid
TriNet Corporate Realty Trust, a Maryland corporation, ("TriNet"), the sum of
$420,000 for the rights to purchase the PWC Building as they were the original
purchasers under the Purchase Agreement, out of which TriNet paid the Seller
$100,000 as a real estate commission.  At the closing, Wells OP paid a purchase
price of $20,707,854 to the Seller plus $98,609.30 for closing costs.  Neither
Seller nor TriNet are affiliated with the Company or its Advisor.
    
     The SouthTrust Loan.  Wells OP purchased the PWC Building subject to a loan
     -------------------                                                        
from SouthTrust Bank, National Association ("SouthTrust") in the outstanding
principal amount of $14,132,537.87 (the "SouthTrust Loan"). The SouthTrust Loan
consists of a revolving credit facility whereby SouthTrust agreed to loan up to
$15.5 million. The SouthTrust Loan matures on December 31, 2000. The interest
rate on the SouthTrust Loan is a variable rate per annum equal to the London
InterBank Offered Rate for a thirty day period plus 185 basis points. Commencing
on February 1, 1999, Wells OP is required to pay to SouthTrust monthly
installments of principal in the amount of $12,500.00 plus accrued interest. The
SouthTrust Loan is secured by a first mortgage against the PWC Building.
     
     Description of the Building and the Site.  The PWC Building is a four-story
     ----------------------------------------                                   
office building with 130,091 rentable square feet located in Tampa, Florida.
The building is constructed using a steel frame design and concrete tilt-up wall
panels.  Construction of the PWC Building was completed in December 1998.  The
parking area contains approximately 600 paved parking spaces, including a two
level parking deck accommodating 312 spaces, approximately 126 of which are
covered.

     An independent appraisal of the PWC Building was prepared by RE Marketing
Consultants, Inc., as of March 2, 1998, pursuant to which the market value of
the land and the leased fee interest subject to the PWC Lease (described below)
was estimated to be $22,000,000, in cash or terms equivalent to cash.  This
value estimate was based upon a number of assumptions, including that the PWC
Building will continue operating at a stabilized level with PWC occupying 100%
of the rentable area, and is not necessarily an accurate reflection of the fair
market value of the property.  Wells OP also obtained an environmental report
prior to closing evidencing that the environmental condition of the land
encompassing the PWC Building was satisfactory.

     The site consists of approximately 9 acres of land located between
Eisenhower Boulevard and George Road approximately 1,250 feet south of West
Hillsborough Avenue.  The site is located in Sunforest Business Park which is
located in the southwest quadrant of the Veteran's Expressway and West
Hillsborough Avenue.  The Sunforest Business Park is located in the Westshore
Business District, which is a suburban business center surrounding Tampa
International Airport.  The total supply of office space in this subsector is
9.8 million square feet, which is 3.57 million square feet larger than the
Downtown Central Business District.  The overall occupancy rate in the Westshore
Business District is 93.5% compared to the countywide occupancy rate of 90.5%.

     According to the 1990 census, the Tampa Bay area, including Tampa, St.
Petersburg and Clearwater, comprises 2.16 million people, and is the 22nd
largest metropolitan area in the United States.  Tampa is bordered on the west
and south by Upper and Old Tampa Bays and is divided by the Hillsborough River.
The City of Tampa is located in Hillsborough County midway down the west coast
of Florida.  In contrast to much of Florida's West

                                       12
<PAGE>
 
Coast, Hillsborough County is relatively young with approximately 87% of the
population under 65 years of age and a median of age 33.2 years.

     The PWC Lease.  On December 31, 1998, the Seller assigned all of its rights
     -------------                                                              
pursuant to the Lease Agreement dated as of March 30, 1998 between the Seller,
as landlord, and Price Waterhouse LLP, which has subsequently merged with
Coopers & Lybrand to form PriceWaterhouseCoopers ("PWC"), as tenant (such
agreement, as assigned, is referred to herein as the "PWC Lease").  The PWC
Lease currently expires in December 2008, subject to PWC's right to extend the
lease for two additional five year periods of time.

     PWC provides a full range of business advisory services to leading global,
national and local companies and to public institutions.  These services include
audit, accounting and tax advice; management, information technology and human
resource consulting; financial advisory services including mergers and
acquisitions, business recovery, project finance and litigation support;
business process outsourcing services; and legal advice through a global network
of affiliated law firms.  PWC employs more than 140,000 people in 152 countries.

     The annual base rent payable under the PWC Lease will be $1,915,741.13
($14.73 per square foot) payable in equal monthly installments of $159,645.09
during the first year of the initial lease term.  The base rent escalates at the
rate of 3% per year throughout the ten year lease term.  In addition, PWC is
required to pay a "reserve" of $13,009.00 ($.10 per square foot) as additional
rent.  Under the PWC Lease, PWC is responsible for the payment of all property
taxes, operating expenses and other repair and maintenance work relating to the
PWC Building.  PWC is also required to reimburse the landlord the cost of
casualty insurance for the property.  Wells OP, as landlord, is responsible for
all maintenance, repairs and replacements to the roof and structural components
of the PWC Building, including without limitation, the roof system, exterior
walls, load bearing walls, foundations, glazing and curtain wall systems.

     The initial term of the PWC Lease is ten years which commenced on December
28, 1998 (the "Rental Commencement Date").  As stated above, PWC has the option
to extend the initial term of the PWC Lease for two additional five year
periods.  Each extension option must be exercised by giving (i) written "non-
binding" notice to the landlord at least 15 months but not more than 18 months
prior to the expiration date of the then current lease term, or (ii) written
"binding" notice to the landlord at least 12 months prior to the expiration date
of the then current lease term.  The annual base rent for each renewal term
under the lease will be equal to the greater of (i) ninety percent (90%) of the
"market rent rate" for such space multiplied by the rentable area of the leased
premises, or (ii) one hundred percent (100%) of the base rent paid during the
last lease year of the initial term, or the then current renewal term, as the
case may be.  If the base rent for the first lease year under the renewal term
is determined pursuant to Clause (i) above, then the base rent for each lease
year of such renewal term after the first lease year shall be one hundred three
percent (103%) of the base rent for the immediately preceding lease year.  If
the base rent for the first lease year of a renewal term is determined pursuant
to Clause (ii) above, then there shall be no escalation of the base rent until
such time that the total base rent paid during the renewal term is equal to the
total base rent that would have been paid during such renewal term if the base
rent had been determined pursuant to Clause (i) above; and thereafter, the base
rent for each subsequent lease year of such renewal term shall be one hundred
three percent (103%) of the base rent for the immediately preceding lease year.

     The "market rent rate" under the PWC lease shall be determined by agreement
of the parties within thirty (30) days after the date on which PWC delivers its
notice of renewal.  If Wells OP and PWC are unable to reach agreement on the
market rent rate within said thirty (30) day period, then each party shall
simultaneously submit to the other in a sealed envelope its good faith estimate
of the market rent rate within seven (7) days of expiration of the thirty (30)
day period.  If the higher of such estimates is not more than one hundred five
percent (105%) of the lower of such estimates then the market rent rate shall be
the average of the two estimates.  Otherwise, within five (5) days either party
may request in writing to resolve the dispute by arbitration.  The "market rate
rent" should be based upon the fair market rent then being charged by landlords
under new leases of office space in the Westshore Business District for similar
space in a building of comparable quality with comparable amenities.

     In addition, the PWC Lease contains an option to expand the premises to
include a second three or four story building with an amount of square feet up
to a total of 132,000 square feet (the "Expansion Building") which, if exercised
by PWC, will require Wells OP to expend funds necessary to construct the
Expansion Building.  PWC

                                       13
<PAGE>
 
may exercise its expansion option by delivering written notice to Wells OP at
any time between the sixtieth (60th) day after the Rental Commencement Date and
the expiration of the initial term of the lease.  If PWC for any reason fails to
deliver the expansion notice on or prior to the last day of the initial term,
the expansion option shall automatically expire.  Upon PWC's delivery of the
expansion notice and commencement of construction of the improvements by Wells
OP, the term of the lease shall automatically be extended for an additional
period of ten (10) years from the date of substantial completion of the
Expansion Building, without further action by either PWC or Wells OP.  During
the first five lease years of the initial term, Wells OP shall be obligated to
construct the Expansion Building if PWC delivers the expansion notice.  Wells OP
and PWC have agreed that Wells OP shall not be required to construct the
Expansion Building, however, if PWC delivers the expansion notice after the end
of the fifth lease year and, following delivery of such expansion notice, Wells
OP determines not to construct the Expansion Building based upon the base rent
it would receive for the Expansion Building.  If Wells OP notifies PWC in
writing of such determination within thirty (30) days after Wells OP's receipt
of the expansion notice, PWC shall have the right to exercise its option to
purchase the PWC building (the "Purchase Option"), as described below.

     If PWC elects to exercise its expansion option, in addition to the
construction of a second building which is of a quality equal to or better than
the PWC building, Wells OP will be required to expand the parking garage such
that a sufficient number of parking spaces, at least equal to four (4) parking
spaces per 1,000 square feet of rentable area, is maintained.  Wells OP agrees
to fund the cost of the design, development and construction of the Expansion
Building up to a maximum of $150.00 per square foot of rentable area, as
increased by increases in the Consumer Price Index between the Rental
Commencement Date and the date of expansion notice (the "Maximum Expansion
Cost").  PWC shall be responsible for the payment of any costs of the Expansion
Building in excess of the Maximum Expansion Cost.

     The base rent per square foot of rentable area payable for the Expansion
Building in the first lease year of such building shall be an amount equal to
the product of (a) the Expansion Building cost per square foot of rentable area
multiplied by (b) the sum of 300 basis points plus the weekly average yield on
United States Treasury Obligations, amortized on an annual basis over a period
of twenty (20) years.  The base rent for each subsequent lease year shall be one
hundred three percent (103%) of the base rent for the immediately preceding
lease year.

     In the event that PWC elects to exercise its expansion option and Wells OP
determines not to proceed with the construction of the Expansion Building as
described above, or if Wells OP is otherwise required to construct the Expansion
Building and fails to do so in a timely basis pursuant to the PWC Lease, PWC may
exercise its Purchase Option by giving Wells OP written notice of such exercise
within thirty (30) days after either such event.  If PWC properly exercises its
Purchase Option, PWC must simultaneously deliver a deposit in the amount of
$50,000 in the form of cash, wire transfer or cashier's check.  The purchase
price for the PWC Building pursuant to the Purchase Option shall be equal to (a)
the average of the monthly base rent for each month remaining in the initial
term as of the closing date on the Purchase Option multiplied by 12 (the
"Average Annual Base Rent"), and (b) the Average Annual Base Rent shall be
multiplied by 11.

     There are no assurances that Wells OP will be able to attract or obtain
suitable replacement tenants for the PWC Building upon the expiration of the PWC
Lease.

PROPERTY MANAGEMENT FEES

     Wells Management Company, Inc. ("Wells Management"), an Affiliate of the
Company and the Advisor, has been retained to manage and lease the PWC Building.
The Company shall pay management and leasing fees to Wells Management in the
amount of 4.5% of gross revenues.

THE STATUS OF THE ABB BUILDING

     On September 10, 1998, a joint venture by and among Wells Fund IX, Wells
Fund X, Wells Fund XI and Wells OP (the "Fund IX-X-XI-REIT Joint Venture"),
entered into a Lease Agreement (the "Temporary Lease") with Associates pursuant
to which Associates has agreed to lease 23,490 rentable square feet of the ABB
Building on a temporary basis until substantial completion of the Project (as
defined in the Associates Lease).  The rental

                                       14
<PAGE>
 
commencement date of the Temporary Lease is September 14, 1998 and the
expiration date of the lease term is May 31, 1999 subject to Associates' right
to extend the Temporary Lease and subject to Associates' right to terminate the
lease in the event the rental commencement date of the Associates Lease takes
place.  In any event, the Temporary Lease may not be extended beyond May 31,
2000.

     The annual base rental rate for the Temporary Lease is $234,900 ($10 per
square foot) payable in equal monthly installments of $19,575 during the term of
the Temporary Lease, subject to an increase to $293,625 ($12.50 per square foot)
payable in equal monthly installments of $24,469 under certain conditions.

     Under the Temporary Lease, Associates is responsible for its share of all
expenses, costs and disbursements (excluding specific costs billed to specific
tenants of the building) of every kind and nature relating to or incurred or
paid in connection with the ownership, management, operation, repair and
maintenance of the ABB Building, including compensation of employees engaged in
the operation and management or maintenance of the ABB Building, supplies,
equipment and materials, utilities, repairs and general maintenance, insurance,
a management fee in the amount of 4% of the gross rental income from the ABB
Building and all taxes and governmental charges attributable to the ABB Building
or its operations (excluding taxes imposed or measured on by the income of the
Fund IX-X-XI-REIT Joint Venture from operation of the ABB Building).

     Under the terms of the Temporary Lease, the Fund IX-X-XI-REIT Joint Venture
is responsible for a construction allowance of $233,155 (calculated at the rate
of $9.50 per square foot of the premises).

THE STATUS OF THE CORT FURNITURE BUILDING

     On September 1, 1998, the Fund X-XI Joint Venture, a Georgia Joint Venture
by and between Wells Fund X and Wells Fund XI, acquired Wells Development's
equity interest in Wells/Orange County Associates, a Georgia joint venture with
Wells OP (the "Cort Joint Venture").  As of January 10, 1999 Wells OP had made
total capital contributions to the Cort Joint Venture of $2,870,982 and held an
equity percentage interest in the Cort Joint Venture of 44%, and the Fund X-XI
Joint Venture made total capital contributions to the Cort Joint Venture of
$3,695,000 and held an equity percentage interest in the Cort Joint Venture of
56%.  Prior to the Fund X-XI Joint Venture's acquisition of an equity interest
in the Cort Joint Venture, the NationsBank Loan previously encumbering the Cort
Furniture Building was paid off and satisfied of record.

THE STATUS OF THE FAIRCHILD BUILDING

     On October 8, 1998, the Fund X-XI Joint Venture acquired Wells
Development's equity interest in Wells/Fremont Associates, a Georgia joint
venture with Wells OP (the "Fremont Joint Venture").  As of January 10, 1999,

NationsBank Loan previously encumbering the Fairchild Building was paid off and
satisfied of record.

THE VANGUARD CELLULAR BUILDING

     Purchase of the Vanguard Cellular Building.  On February 4, 1999, Wells OP
     ------------------------------------------                                
acquired a four-story office building containing approximately 81,859 rentable
square feet which was recently developed on an approximately 10.5 acre tract of
real property located in Harrisburg, Dauphin County, Pennsylvania.

     Wells OP purchased the Vanguard Cellular Building from Walsh Higgins No.
33, L.P. ("Walsh Higgins") for a purchase price of $12,291,200 pursuant to the
terms of the Agreement for the Purchase and Sale of Property dated November 30,
1998.  At the closing, Wells OP incurred acquisition expenses, including
transfer taxes, title insurance premiums, recording fees and tax proration
items, of approximately $161,700.  In addition, Wells OP paid legal fees of
approximately $50,000 outside of closing.  Wells OP expended cash proceeds in
the amount of $6,332,100 and obtained a loan in the amount of $6,425,000 from
NationsBank, N.A., the net proceeds of which were used to fund the remainder of
the purchase price of the Vanguard Cellular Building (the "Vanguard Loan").
Walsh Higgins is not affiliated with the Company or the Advisor.

     The Vanguard Loan.  The Vanguard Loan matures on January 4, 2002.  The
     -----------------                                                     
interest rate on the Vanguard Loan is a fixed rate equal to the rate appearing
on Telerate Page 3750 as the London InterBank Offered Rate plus 200 basis points
over a six month period.  The interest rate is fixed for the initial six months
of the loan at 7% per annum.  A principal installment in the amount of
$6,150,000 is due and payable by Wells OP on August 1, 1999.  Thereafter, Wells
OP is required to make quarterly installments of principal in an amount equal to
one-ninth of the outstanding principal balance as of October 1, 1999.  The
Vanguard Loan is secured by a first mortgage against the Vanguard Cellular
Building.  Leo F. Wells, III (an officer and director of the Company and the
Advisor), and the Company are co-guarantors of the Vanguard Loan.  Wells OP
incurred loan expenses, including legal fees, loan origination fees and
appraisal fees, of approximately $29,000 in connection with obtaining the
Vanguard Loan.

     Description of the Building and the Site.  The Vanguard Cellular Building
     ----------------------------------------                                 
is a four-story office building with 81,859 rentable square feet consisting of
over 24,000 square feet of gross floor area on each of first three levels and
approximately 8,200 square feet of gross floor area on the lower level.  The
building is constructed using a steel frame design and finished with a high
quality brick masonry exterior.  Construction of the Vanguard Cellular Building
was completed in November 1998.  The parking area contains approximately 570
paved parking spaces.

     An independent appraisal of the Vanguard Cellular Building was prepared by
CB Richard Ellis, Inc., real estate appraisers, as of December 1, 1998, pursuant
to which the market value of the land and the leased fee interest subject to the
Vanguard Cellular Lease (described below) was estimated to be $13,100,000, in
cash or terms equivalent to cash.  This value estimate was based upon a number
of assumptions, including that the Vanguard Cellular Building will continue
operating at a stabilized level with Pennsylvania Cellular Telephone Corp.
("Pennsylvania Telephone"), a North Carolina corporation and wholly owned
subsidiary of Vanguard Cellular Systems, Inc. ("Vanguard Cellular"), occupying
100% of the rentable area, and is not necessarily an accurate reflection of the
fair market value of the property.  Wells OP also obtained an environmental
report prior to closing evidencing that the environmental condition of the land
encompassing the Vanguard Cellular Building was satisfactory.

     The site is located in the Lower Paxton Township, a suburb of Harrisburg in
Dauphin County, Pennsylvania.  The site consists of approximately 10.5 acres of
land in Commerce Park, a planned business park, at the intersection of Progress
Avenue and Interstate Drive just off of the Progress Avenue exit of Interstate
81.  The Greater Harrisburg Area is subdivided into three submarkets:  the
Downtown Business District; the East Shore Business District; and the West Shore
Business District.  The Greater Harrisburg Area's office building market is
evenly distributed among the three submarkets with no one submarket containing
more than thirty-eight percent (38%) of the total office buildings.  The
Vanguard Cellular Building is located in the East Shore Business District on the
eastern side of the Susquehanna River approximately 10 miles northeast of the
Downtown Business District.

     Harrisburg is the capital of the State of Pennsylvania, and is well
positioned to take advantage of the established road, rail and water
transportation systems in the northeast region.  Harrisburg is located
approximately 100 miles west of Philadelphia, approximately 195 miles east of
Pittsburgh, approximately 75 miles north of Baltimore and approximately 90 miles
north of Washington, D.C.  This central location allows Harrisburg to take
advantage of the economic, trade and industrial activities that occur in the
region.  Over the past several years, the Harrisburg area has experienced
increases in population, income levels and employment.  In fact, the
unemployment rate in Dauphin County is considerably lower than the statewide and
national rates.  The Harrisburg area's economy is based principally in the
industrial and manufacturing, government and services sectors.

     The Vanguard Cellular Lease.  The Vanguard Cellular Building is leased to
     ---------------------------                                              
Pennsylvania Telephone, a subsidiary of Vanguard Cellular, pursuant to the
Build-To-Suit Office Lease Agreement dated as of September 26, 1997, as amended
by instruments on September 15, 1998 and January 18, 1999 (the "Vanguard
Cellular Lease").  At the closing of the Vanguard Cellular Building, the Walsh
Higgins assigned all of its rights to the Vanguard Cellular Lease to Wells OP.

     Vanguard Cellular is an independent operator of cellular telephone systems
in the United States with over 664,000 subscribers located in twenty-six markets
in the Mid-Atlantic, Ohio Valley and New England regions of the United States.
Vanguard Cellular markets its wireless products and services under the name
CellularOne, a nationally recognized brand name partially owned by Vanguard
Cellular.  Vanguard Cellular operates primarily in

                                       2
<PAGE>
 
suburban and rural areas that are close in proximity to major urban areas, which
it believes affords several advantages over its traditional urban competitors,
including (i) greater network capacity, (ii) greater roaming revenue
opportunities, (iii) lower distribution costs, and (iv) higher barriers to entry
by competitors.  The obligations of Pennsylvania Telephone under the Vanguard
Cellular Lease are guaranteed by Vanguard Cellular, which reported net income in
excess of $74 million on revenues in excess of $420 million and a net worth in
excess of $100 million for the year ended December 31, 1998.

     As of October 2, 1998, Vanguard Cellular had entered into a definitive
merger agreement, as amended, with AT&T Corp. pursuant to which Vanguard
Cellular will be merged with and into a wholly owned subsidiary of AT&T.  The
board of directors of each company have approved the merger.  However, the
transaction is subject to the approval of Vanguard Cellular's shareholders and
certain other conditions.  A special meeting of Vanguard Cellular's shareholders
to consider the merger is scheduled for April 27, 1999.

     The initial term of the Vanguard Cellular Lease is ten years which
commenced on November 16, 1998 (the "Vanguard Commencement Date").  Vanguard has
the option to extend the initial term of the Vanguard Cellular Lease for three
additional five year periods and one additional four year and eleven month
period.  Each extension option must be exercised by giving written notice to the
landlord at least twelve months prior to the expiration date of the then current
lease term.  The following table summarizes the annual base rent payable during
the initial term of the Vanguard Cellular Lease:

</TABLE>

     The annual base rent for each extended term under the lease will be equal
to 93% of the "fair market rent" determined either (i) as agreed upon by the
parties, or (ii) as determined by appraisal pursuant to the terms and conditions
of the Vanguard Cellular Lease.  The fair market rent shall be multiplied by the
"fair market escalator" (which represents the yearly rate of increases in the
fair market rent for the entire renewal term), if any.  If the fair market rent
is to be determined by appraisal, both the landlord and the tenant shall
designate an independent appraiser, and both appraisers shall mutually designate
a third appraiser.  After their appointment, the appraisers shall determine the
fair market rent and the fair market escalator by submitting independent
appraisals.  The fair market rent and fair market escalator shall be deemed to
be the middle appraisal of the three submitted.

     Under the Vanguard Cellular Lease, the tenant is required to pay as
additional rent all real estate taxes, special assessments, water rates and
charges, sewer rates and charges, public utilities, insurance premiums, street
lighting, excise levies, licenses, permits, governmental inspection fees and
other governmental charges and all other charges incurred in the use, occupancy,
operation, leasing or possession of the Vanguard Cellular Building.  In
addition, the tenant is responsible for all routine maintenance and repairs
relating to the Vanguard Cellular Building.  Wells OP, as the landlord, is
responsible for (i) maintenance, repairs and replacements to the structural
components of the Vanguard Cellular Building, including without limitation, the
roof, floor slabs, foundation walls and footings, structural steel, exterior
walls, driveways, roadways, sidewalks, curbs, parking areas and loading areas,
and (ii) making necessary capital replacements of the heating, ventilation and
air condition system, electrical, plumbing, fire protection and other mechanical
systems in the building.

                                       3

     In addition, the Vanguard Cellular Lease contains an option to expand the
premises to create additional office space of not less than 40,000 gross square
feet and not more than 90,000 gross square feet, as well as additional parking
to accommodate such office space (the "Expansion Improvements").  If
Pennsylvania Telephone exercises its option for the Expansion Improvements,
Wells OP will be obligated to expend the funds necessary to construct the
Expansion Improvements.  Pennsylvania Telephone may exercise its expansion
option by delivering written notice to Wells OP at any time before the last
business day of the 96th month of the initial term of the Vanguard Cellular
Lease.

     Within 60 days after Wells OP's receipt of the expansion notice, Wells OP
shall consult with Pennsylvania Telephone concerning Pennsylvania Telephone's
specific requirements with regard to the Expansion Improvements and, within such
60 day period, Wells OP shall notify Pennsylvania Telephone in writing of the
total estimated expansion costs to be incurred in planning and constructing the
Expansion Improvements.  Within 60 days after Pennsylvania Telephone receives
Wells OP's written notification of the costs for the Expansion Improvements,
Pennsylvania Telephone shall notify Wells OP in writing either (i) that
Pennsylvania Telephone authorizes Wells OP to proceed with the construction of
the Expansion Improvements, (ii) that Pennsylvania Telephone intends to submit
revised specifications within 60 days to reduce the estimated costs of the
Expansion Improvements to an amount satisfactory to Pennsylvania Telephone, or
(iii) that Pennsylvania Telephone elects not to expand the premises.  If
Pennsylvania Telephone fails to deliver its notice to proceed within the above
mentioned 60 day period, then Pennsylvania Telephone shall be deemed to have
elected not to expand.

     If Pennsylvania Telephone delivers its notice to proceed with the Expansion
Improvements, Pennsylvania Telephone shall be deemed to have exercised its
option for such full or partial renewal terms such that, as of the date of
substantial completion of the Expansion Improvements, the remaining lease term
shall be ten years from such date of substantial completion.  Pennsylvania
Telephone shall continue to have the right to exercise its option for any of the
renewal terms discussed above which remain beyond the ten year additional term;
provided that, if the remaining portion of a renewal term after the ten year
extension shall be less than one year, then the ten year term shall be further
extended to include the remaining portion of the renewal term which is less than
one year.

     The annual base rent for the Expansion Improvements for the first twelve
months shall be equal to the product of (i) expansion costs, multiplied by (ii)
a factor of 1.07, multiplied by (iii) the greater of (A) 10.50%, or (B) an
annual interest rate equal to 375 basis points in excess of the ten year United
States Treasury Note Rate then most recently announced by the United States
Treasury as of the commencement date of the Expansion Improvements (the
"Expansion Commencement Date").  Thereafter, the annual base rent for the
Expansion Improvements shall be increased annually by the lesser of (a) 5%, or
(b) 75% of the percentage by which the United States, Bureau of Labor
Statistics, Consumer Price Index for All Items - All Urban Wage Earners and
Clerical Workers for the Philadelphia Area (the "CPI Index") published nearest
to the expiration date of each twelve month period subsequent to the Expansion
Commencement Date is greater than the CPI Index most recently published prior to
the Vanguard Commencement Date.

     Management of the Company believes that the Vanguard Cellular Building has
been adequately insured against loss from fire, windstorm, hail, explosion,
vandalism, riot and civil commotion, damage from vehicles and aircraft, smoke
damage, water damage, and such other risks or hazards which are customarily
insured against with respect to improvements similar in design, construction,
general location, use and occupancy to the Vanguard Cellular Building.
Management also believes that the Vanguard Cellular Building is adequately
insured against claims for bodily injury, personal injury or property damage for
any loss, liability or damage that may occur on the premises.

THE MATSUSHITA PROPERTY

     Purchase of the Matsushita Property.  On March 15, 1999, Wells OP purchased
     -----------------------------------                                        
an 8.837 acre tract of land located in Lake Forest, Orange County, California
(the "Matsushita Property") pursuant to that certain Purchase and Sale Agreement
and Joint Escrow Instructions dated February 17, 1999 between Wells OP and MSGW
California I, L.L.C., a Delaware limited liability company ("MSGW").  The
purchase price for the Matsushita Property was $4,450,230.  In connection with
the closing of the acquisition of the Matsushita Property, Wells OP paid title
insurance premiums and other miscellaneous closing costs of approximately
$16,000.  Wells OP paid legal fees of $39,514 outside of the closing.  MSGW is
not affiliated with the Company or the Advisor.

     Wells OP entered into a Development Agreement (as described below) for the
construction of a two-story office building containing approximately 150,000
rentable square feet to be erected on the Matsushita Property (the "Matsushita
Project").  Wells OP entered into an Office Lease (the "Matsushita Lease") with
Matsushita Avionics Systems Corporation, a Delaware corporation ("Matsushita
Avionics"), pursuant to which Matsushita Avionics agreed to lease all of the
Matsushita Project upon its completion.

     Termination of Existing Lease.  Matsushita Avionics is currently a tenant
     -----------------------------                                            
of a building located at 15253 Bake Parkway, Irvine, California (the "Existing
Building") pursuant to an Office Lease dated April 29, 1996 (the "Existing
Lease").  The Existing Building is owned by Fund VIII and Fund IX Associates
(the "Fund VIII-IX Joint Venture"), a Georgia joint venture between Wells Real
Estate Fund VIII, L.P. and Wells Real Estate Fund IX, L.P., both of which are
Affiliates of the Company and the Advisor.  Matsushita Avionics and the Fund
VIII-IX Joint Venture have entered into a Lease and Guaranty Termination
Agreement dated February 18, 1999 pursuant to which Matsushita Avionics will be
vacating the Existing Building and relieved of any of its obligations under the
Existing Lease upon the Matsushita Commencement Date of the Matsushita Lease, as
described below.

     Rental Income Guaranty by Wells OP.  In consideration for the Fund VIII-IX
     ----------------------------------                                        
Joint Venture releasing Matsushita Avionics from its obligations under the
Existing Lease and thereby allowing Wells OP to enter into the Matsushita Lease
with Matsushita Avionics, Wells OP entered into a Rental Income Guaranty
Agreement dated as of February 18, 1999, whereby Wells OP guaranteed the Fund
VIII-IX Joint Venture that it will receive rental income on the Existing
Building at least equal to the rent and building expenses that the Fund VIII-IX
Joint Venture would have received over the remaining term of the Existing Lease.

     Description of the Matsushita Project and the Site.  The Matsushita Project
     --------------------------------------------------                         
involves the construction of a two-story office building containing 150,000
rentable square feet.  The building will be constructed using concrete tilt-up
walls and high performance glass with parking for approximately 600 vehicles.
The Matsushita Property is currently zoned to permit the intended development
and operation of the Matsushita Project as a commercial office building and has
access to all utilities necessary for the development and operation of the
Matsushita Project, including water, electricity, sanitary sewer and telephone.

     The site consists of an 8.837 acre tract of land located in the Pacific
Commercentre, which is a 33 acre master-planned business park positioned near
the Irvine Spectrum in the heart of Southern California's Technology Coast.
Pacific Commercentre is a nine building complex featuring office, technology,
and light manufacturing uses, and is located in the city of Lake Forest in
Southern Orange County with easy access to the Foothill Transportation Corridor
and the San Diego Freeway.  The John Wayne Airport is located approximately
eight miles from the site.

     The City of Lake Forest was incorporated in 1991, and is located between
the cities of Irvine and Mission Viejo.  Lake Forest is experiencing growth as a
result of northeastern expansion of already developed areas of Orange County.
One of the major factors in the recent growth is its location along the route of
the Foothill Transportation Corridor, a planned tollway with one leg of
construction that has been completed in the vicinity of the Pacific
Commercentre.  Existing land uses in the area include residential tracts of
varying densities and small commercial centers.  There are several large ranches
that are planned for development as master planned communities containing a
variety of residential, commercial and industrial uses.

     An independent appraisal of the Matsushita Project dated March 16, 1999 was
prepared by CB Richard Ellis, Inc., real estate appraisers, pursuant to which
the market value of the land and the leased fee interest in the

                                       5
<PAGE>
 
Matsushita Project subject to the Matsushita Lease (described below) was
estimated to be $18.9 million, in cash or terms equivalent to cash, as of
December 21, 1999 (the anticipated completion date).  This value estimate was
based upon a number of assumptions, including that the Matsushita Project will
be finished in accordance with plans and specifications, that total development
costs would not exceed $17.8 million and that the building will be operated
following completion at a stabilized level with Matsushita Avionics occupying
100% of the building at a rental rate calculated based upon the $17.8 million
development budget.  Prior to closing of the Matsushita Loan (described below),
NationsBank will obtain a revised independent appraisal of the Matsushita
Property reflecting a value estimate based upon a development budget of $18.4
million.  Wells OP obtained an environmental report prior to closing of the
Matsushita Property evidencing that the environmental condition of the
Matsushita Property is satisfactory.

     The Matsushita Project Loans.  Wells OP obtained $3,500,000 in additional
     ----------------------------                                             
financing for the Matsushita Project from SouthTrust Bank, N.A. pursuant to the
revolving credit facility (the "SouthTrust Loan") extended to Wells OP in
connection with the acquisition of the PriceWaterhouseCoopers Building in Tampa,
Florida (the "PWC Building"), which is secured by a first mortgage against the
PWC Building.  See Supplement No. 6 to the Prospectus for a discussion of the
terms of the SouthTrust Loan.  Subsequent to the acquisition of the PWC
Building, the Company had used the proceeds from the sale of its shares to pay-
down the balance of the SouthTrust Loan to zero, leaving in place a revolving
credit facility secured by the PWC Building available to fund additional
property acquisitions.

     In addition, Wells OP obtained a commitment for a construction loan from
NationsBank, N.A. ("NationsBank") in the maximum principal amount of
$15,375,000, the proceeds of which will be used to fund the development and
construction of the Matsushita Project (the "Matsushita Loan").  The Matsushita
Loan shall mature 24 months from the date of the loan closing.  The interest
rate on the Matsushita Loan will be a variable rate equal to either (1) the
NationsBank "prime rate," or (2) at the option of Wells OP, the rate per annum
appearing on Telerate Page 3750 as the London Inter Bank Offered Rate for a 30
day period, plus 200 basis points.  Wells OP will make monthly installments of
interest and, commencing one year after the date of the loan closing, Wells OP
will make monthly installments of principal in the amount of $10,703 until
maturity.  On the maturity date, the entire outstanding principal balance plus
any accrued but unpaid interest shall be due and payable.  At the closing, Wells
OP will pay a nonrefundable origination fee of $76,900 to NationsBank.  The
Matsushita Loan will be secured by a first priority mortgage against the
Matsushita Project.  Leo F. Wells, III (an officer and director of the Company
and the Advisor) and the Company will be co-guarantors of the Matsushita Loan.
The Matsushita Loan, if obtained, will result in 100% financing of the
Matsushita Project.

     Although management of Wells OP currently anticipates obtaining the
Matsushita Loan from NationsBank as described above, Wells OP has not yet
entered into a loan agreement.  Therefore, there is no guarantee that Wells OP
will obtain the Matsushita Loan or that the loan obtained to fund the Matsushita
Project will be on the terms described above.

     Development Agreement.  On March 31, 1999, Wells OP entered into a
     ---------------------                                             
Development Agreement (the "Development Agreement") with ADEVCO Corporation, a
Georgia corporation (the "Developer"), as the exclusive development manager to
supervise, manage and coordinate the planning, design, construction and
completion of the Matsushita Project.

     The Developer is an Atlanta based real estate development and management
company formed in 1990 which specializes in the development of office buildings.
The Developer has previously developed or is developing a total of seven office
buildings for Affiliates of the Advisor.  See Supplement No. 6 to the Prospectus
for a description of the Developer and projects previously developed by the
Developer.

     The primary responsibilities of the Developer under the Development
Agreement include:

     .    the supervision, coordination, administration and management of the
          work, activities and performance of the architect under the
          Architect's Agreement (as described below) and the contractor under
          the Construction Contract (as described below);

                                       6
<PAGE>
 
     .    the implementation of a development budget setting forth an estimate
          of all expenses and costs to be incurred with respect to the planning,
          design, development and construction of the Matsushita Project;

     .    the review of all applications for disbursement made by or on behalf
          of Wells OP under the Architect's Agreement and the Construction
          Contract;

     .    the supervision and management of tenant build-out at the Matsushita
          Project; and

     .    the negotiation of contracts with, supervision of the performance of,
          and review and verification of applications for payment of the fees,
          charges and expenses of such design and engineering professionals,
          consultants and suppliers as the Developer deems necessary for the
          design and construction of the Matsushita Project in accordance with
          the development budget.

     The Developer will also perform other services typical of development
managers including, but not limited to, arranging for preliminary site plans,
surveys and engineering plans and drawings, overseeing the selection by the
Contractor of major subcontractors and reviewing all applicable building codes,
environmental, zoning and land use laws and other applicable local, state and
federal laws, regulations and ordinances concerning the development, use and
operation of the Matsushita Project or any portion thereof.  The Developer is
required to advise Wells OP on a weekly basis as to the status of the Matsushita
Project and submit to Wells OP monthly reports with respect to the progress of
construction, including a breakdown of all costs and expenses under the
development budget.  The Developer is required to obtain prior written approval
from Wells OP before incurring and paying any costs which will result in
aggregate expenditures under any one category or line item in the development
budget exceeding the amount budgeted therefor.  If the Developer determines at
any time that the development budget is not compatible with the then prevailing
status of the Matsushita Project and will not adequately provide for the
completion of the Matsushita Project, the Developer will prepare and submit to
Wells OP for approval an appropriate revision of the development budget.

     In discharging its duties and responsibilities under the Development
Agreement, the Developer has full and complete authority and discretion to act
for and on behalf of Wells OP.  The Developer has agreed to indemnify Wells OP
from any and all claims, demands, losses, liabilities, actions, lawsuits, and
other proceedings, judgments and awards, and any costs and expenses arising out
of the negligence, fraud or any willful act or omission by the Developer.  Wells
OP has agreed to indemnify the Developer from and against any and all claims,
demands, losses, liabilities, actions, lawsuits and other proceedings, judgments
and awards, and any costs and expenses arising out of (1) any actions taken by
the Developer within the scope of its duties or authority, excluding negligence,
fraud or willful acts of the Developer, and (2) the negligence, fraud or any
willful act or omission on the part of Wells OP and its partners and their
respective officers, directors and employees.

     Wells OP may elect to provide funds to the Developer so that the Developer
can pay Wells OP's obligations with respect to the construction and development
of the Matsushita Project directly.  All such funds of Wells OP which may be
received by the Developer with respect to the development or construction of the
Matsushita Project will be deposited in a bank account approved by Wells OP.  If
at any time the funds contained in the bank account of Wells OP temporarily
exceeds the immediate cash needs of the Matsushita Project, the Developer may
invest such excess funds in savings accounts, certificates of deposit, United
States Treasury obligations and commercial paper as the Developer deems
appropriate or as Wells OP may direct, provided that the form of any such
investment is consistent with the Developer's need to be able to liquidate any
such investment to meet the cash needs of the Matsushita Project.  The Developer
shall be reimbursed for all advances, costs and expenses paid for and on behalf
of Wells OP.  The Developer will not be reimbursed, however, for its own
administrative costs or for costs relating to travel and lodging incurred by its
employees and agents.  The Developer may be required to advance its own funds
for the payment of any costs or expenses incurred by or on behalf of Wells OP in
connection with the development of the Matsushita Project if there are cost
overruns in excess of the contingency contained in the development budget.

                                       7
<PAGE>
 
     As compensation for the services to be rendered by the Developer under the
Development Agreement, Wells OP will pay a development fee of $250,000.  The fee
will be due and payable ratably (on the basis of the percentage of construction
completed) as the construction and development of the Matsushita Project is
completed.

     It is anticipated that the aggregate of all costs and expenses to be
incurred by Wells OP with respect to the acquisition of the Matsushita Property,
the planning, design, development, construction and completion of the Matsushita
Project, the build-out of tenant improvements under the Matsushita Lease and the
contingency reserve will total approximately $18,400,000.  The development
budget may be adjusted upward or downward based upon changes agreed to by Wells
OP and Matsushita Avionics.  Since the development budget has not yet been
finalized as of the date of this Supplement, a detailed breakdown of costs is
not available at this time.

     Under the terms of the Development Agreement, the Developer has agreed
that, in the event that the total of all such costs and expenses exceeds
$18,400,000 (except for changes agreed to by Wells OP and Matsushita Avionics),
the amount of fees payable to the Developer shall be reduced by the amount of
any such excess.  Unless the fees otherwise payable to the Developer are reduced
as set forth above, it is estimated that the total sums due and payable to the
Developer under the Development Agreement will be approximately $250,000.

     In the event the Developer should for any reason cease to manage the
development of the Matsushita Project, Wells OP would have to locate a suitable
successor development manager.  No assurances can be given as to whether a
suitable successor development manager could be found, or what the contractual
terms or arrangement with any such successor would be.

     Construction Contract.  Wells OP anticipates entering into a construction
     ---------------------                                                    
contract (the "Construction Contract") with the general contracting firm of
GWGC, Inc. doing business as Gordon & Williams General Contractors, Inc. (the
"Contractor") for the construction of the Matsushita Project.  The Contractor is
a California corporation based in Laguna Hills, California specializing in
commercial, industrial, amusement park and office buildings.  The Contractor
commenced operations in 1990.  The Contractor is presently engaged in the
construction of ten projects with a total construction value of in excess of $72
million, and since 1993, has completed 45 projects with a total construction
value in excess of $1.9 billion.  It is anticipated that the Contractor will
begin construction of the Matsushita Project in May 1999.

     The Construction Contract will provide that Wells OP shall pay the
Contractor a fee equal to 3% of the cost of the work performed by the
Contractor, as adjusted by approved change orders, for the construction of the
Matsushita Project, excluding tenant improvements.  The Contractor will be
responsible for all costs of labor, materials, construction equipment and
machinery necessary for completion of the Matsushita Project.  In addition, the
Contractor will be required to secure and pay for any additional business
licenses, tap fees and building permits which may be necessary for construction
of the Matsushita Project.  Under the Construction Contract, the cost of the
work and the Contractor's fees will be guaranteed not to exceed $6,500,000 (the
"Guaranteed Maximum Price"), subject to additions and deductions by approved
change orders.  To the extent that costs incurred by the Contractor exceed such
Guaranteed Maximum Price, the Contractor will be required to pay all such costs
without reimbursement by Wells OP.

     Any amounts saved by the Contractor as a result of bids awarded or
subcontracted at amounts below the approved costs for such items shall be set
aside as a contingency reserve.  The Contractor may only be reimbursed from the
contingency reserve for reasonable costs incurred in connection with certain
unknown and unforeseeable risks enumerated in the Construction Contract, and
only to the extent that such costs will not cause the Contractor to exceed the
Guaranteed Maximum Price.  In the event that, at the time of final completion,
the total aggregate sum of the actual cost of the work, the Contractor's fees
and any amounts incurred to remedy defects in the work is less than the
Guaranteed Maximum Price, the difference shall be divided evenly by the
Contractor and Wells OP.

     Wells OP will make monthly progress payments to the Contractor in an amount
of 90% of the portion of the contract price properly allocable to labor,
materials and equipment, less the aggregate of any previous payments made by
Wells OP.  Wells OP will pay the entire unpaid balance when the Matsushita
Project has been fully completed in accordance with the terms and conditions of
the Construction Contract.  As a condition of final payment, the Contractor will
be required to execute and deliver a release of all claims and liens against
Wells OP.

                                       8
<PAGE>
 
     The Contractor will be responsible to Wells OP for the acts or omissions of
its subcontractors and suppliers of materials and of persons either directly or
indirectly employed by them.  The Contractor will agree to indemnify Wells OP
from and against all liability, claims, damages, losses, expenses and costs of
any kind or description arising out of or in connection with the performance of
the Construction Contract, provided that such liability, claim, damage, loss or
expense is caused in whole or in part by any action or omission of the
Contractor, any subcontractor or materialmen, anyone directly or indirectly
employed by any of them or anyone for whose acts any of them may be liable.  The
Construction Contract will also require the Contractor to obtain and maintain,
until completion of the Matsushita Project, adequate insurance coverage relating
to the Matsushita Project, including insurance for workers' compensation,
personal injury and property damage.
 
     The Contractor will be required to work expeditiously and diligently to
maintain progress in accordance with the construction schedule and to achieve
substantial completion of the Matsushita Project within the contract time.  The
Contractor will be required to employ all such additional labor, services and
supervision, including such extra shifts and overtime, as may be necessary to
maintain progress in accordance with the construction schedule.  It is
anticipated that the Matsushita Project will be completed on or before December
20, 1999.  Wells OP shall obtain a completion and performance bond in an amount
sufficient to complete construction and development of the Matsushita Project to
reduce the risk of non-performance and to assure compliance with approved plans
and specifications.  In addition, performance by the Contractor of the
Construction Contract has been personally guaranteed by David Kraxberger, a
principal of the Developer.

     Architect's Agreement.  Ware & Malcomb Architects, Inc. (the "Architect")
     ---------------------

be paid $311,236 for these services.  During the bidding or negotiation phase,
the Architect will assist Wells OP in obtaining bids or negotiated proposals and
assist in awarding and preparing contracts for construction.  The Architect will
be paid $31,124 for these services.  During the construction phase, the
Architect is to provide administration of the Construction Contract and advise
and consult with the Developer and Wells OP concerning various matters relating
to the construction of the Matsushita Project.  The Architect is required to
visit the Matsushita Project site at intervals appropriate to the stage of
construction and to become generally familiar with the progress and quality of
the work and to determine if, in general, the work is proceeding in accordance
with the contract schedule.  The Architect is required to keep Wells OP informed
of the progress and quality of the work.  The Architect is also required to
determine the amounts owing to the Contractor based on observations of the site
and evaluations of the Contractor's application for payment and shall issue
certificates for payment in amounts determined in accordance with the

inspections to determine the date of completion of the Matsushita Project and
shall issue a final certificate for payment.  The Architect will be paid $62,247
for its services performed during the construction phase.

     The total amount of fees payable to the Architect under the Architect's
Agreement is $622,472.  Payments are being paid to the Architect on a monthly
basis in proportion to the services performed within each phase of

                                       9

service.  In addition, the Architect and its employees and consultants are
reimbursed for expenses including, but not limited to, transportation in
connection with the Matsushita Project, living expenses in connection with out-
of-town travel, long distance communications and fees paid for securing approval
of authorities having jurisdiction over the Matsushita Project.  It is estimated
that the total reimbursable expenses in connection with the development of the
Matsushita Project will be approximately $60,000.

     Matsushita Lease.  On February 18, 1999, Wells OP entered into an Office
     ----------------                                                        
Lease (the "Matsushita Lease") pursuant to which Matsushita Avionics agreed to
lease 100% of the 150,000 rentable square feet of the Matsushita Project.

     Matsushita Avionics is a wholly owned subsidiary of Matsushita Electric
Corporation of America ("Matsushita Electric"), a Delaware corporation.
Matsushita Avionics manufactures and sells audiovisual products to the airline
industry for passenger use in airplanes.  Matsushita Electric is a wholly owned
subsidiary of Matsushita Electric Industrial Co., Ltd. ("Matsushita
Industrial"), a Japanese company which is the world's largest consumer
electronics manufacturer.  Matsushita Electric oversees the North American
operations of Matsushita Industrial.  In North America, Matsushita Electric
makes consumer, commercial and industrial electronics, including products
ranging from juke boxes to flat digital television sets, primarily under the
Panasonic brand name.  Matsushita Electric has more than 20 plants in the U.S.,
Mexico and Canada and employs over 23,000 people.  Matsushita Electric has
guaranteed the obligations of Matsushita Avionics under the Matsushita Lease.
Matsushita Electric reported net income for the fiscal year ended March 31, 1998
of over $709 million on gross revenues of over $8 billion and a net worth of
over $1.2 billion.

     The initial term of the Matsushita Lease will be seven years to commence
(the "Matsushita Commencement Date") on the earlier of (1) the date Matsushita
Avionics commences business in the premises, or (2) the date upon which a series
of conditions are met, including but not limited to, Wells OP's completion of
the improvements and a certificate of occupancy is issued.  Matsushita Avionics
has the option to extend the initial term of the Matsushita Lease for two
successive five year periods.  Each extension option must be exercised not more
than 19 months and not less than 15 months prior to the expiration of the then
current lease term.

     The monthly base rent payable under the Matsushita Lease shall be as
follows:

 
                                 Monthly Installment
               Lease Year               of Base Rent
               ----------               ------------
 
                  1-2                     $152,500
                  3-4                     $162,260
                  5-6                     $172,020
                   7                      $181,780

     The monthly base rent is based upon a projected total cost for the
Matsushita Project of $17,847,769.  If the total project cost, as provided in
the work letter attached as an exhibit to the Matsushita Lease, is more or less
than $17,847,769, then the monthly base rent shall be adjusted upward or
downward, as the case may be, by ten percent (10%) of the difference.

     The monthly base rent payable during the option term shall be ninety-five
percent (95%) of the stated rental rate at which, as of the commencement of the
option term, tenants are leasing non-expansion, non-affiliated, non-sublease,
non-encumbered, non-equity space comparable in size, location and quality to the
Matsushita Project for a term of five years in the Lake Forest and Irvine area
of Southern California.  The monthly base rent during the option term shall be
adjusted upward during the option term at the beginning of the 24th and 48th
month of each option term by an amount equal to six percent (6%) of the monthly
base rent payable immediately preceding such period.  Within 30 days of tenant
providing written notice of its intent to exercise a renewal option, Wells OP
shall deliver to Matsushita Avionics notice containing the proposed rent for the
option term.  If, after reasonable good faith efforts, landlord and tenant are
unable to agree upon the option rent before the 13th month prior to the
expiration of the appropriate lease term, option rent shall be determined by
arbitration.

                                       10
<PAGE>
 
     In addition to the monthly base rent, Matsushita Avionics is required to
pay additional rent equal to all "operating expenses" and "tax expenses" during
the lease term.  "Operating expenses" is defined to include all direct and
indirect costs, expenses and assessments charged to the real property with
respect to its efficient and economical operation, management, use, maintenance
and repair, including insurance premiums.  Tax expenses shall mean all federal,
state, county or local government taxes, fees or other impositions of every kind
and nature in connection with the ownership, leasing and operation of the
Matsushita Project.  Matsushita Avionics shall also be responsible for the
furnishing of all services and utilities to the premises, including but not
limited to, heating, ventilation and air conditioning, electricity, water,
telephone, janitorial and security services, window washing and landscaping
services.

     Under the terms of the Matsushita Lease, Matsushita Avionics shall operate,
keep, and maintain, and as necessary, repair, restore, replace, and make any
capital improvements to the structural portions of the building, including the
ceilings, floor surface, interior walls and wall covering, shafts, stairs,
parking areas, stairwells, elevator cabs, washrooms, and building mechanical,
electrical, gas, plumbing and sprinkler systems.  Wells OP shall maintain and
repair the structural skeleton of the building consisting only of the floor
slabs, foundation, roof structure, roof membrane, exterior walls and exterior
glass and mullions.

Matsushita Project, property management and leasing services will be performed
by Wells Management Company, Inc. (the "Property Manager"), an Affiliate of the
Company and the Advisor.  As compensation for its services, the Property Manager
will receive fees equal to 4.5% of the gross revenues for property management
services and leasing services with respect to the Matsushita Project.  In
addition, the Property Manager will receive a one-time initial lease-up fee
relating to the Matsushita Lease equal to the first month's rent plus 5% of the
gross revenues over the initial term of the Matsushita Lease.

MANAGEMENT

     The information contained on page 35 in the "Compensation of Directors and
Officers" subsection of the "Management" section of the Prospectus is revised as
of the date of this Supplement by the deletion of that full paragraph and the
insertion of the following in lieu thereof:

          Each Independent Director of the Board of Directors is paid a fee of
     $250 for each board meeting attended by such director.  All directors
     receive reimbursement of reasonable out-of-pocket expenses incurred in
     connection with meetings of the Board of Directors.  No director who is
     also an officer of the Company receives separate compensation for services
     rendered as a director.

          On March 17, 1999, the Board of Directors adopted the Wells Real
     Estate Investment Trust, Inc. Independent Director Stock Option Plan (the
     "Plan") to foster and promote the long-term financial success of the
     Company by providing an incentive to persons not affiliated with the
     Company to serve as directors through stock ownership in the Company.  If
     the Plan is approved by the Shareholders at the upcoming 1999 Annual
     Meeting of Shareholders, each of the seven Independent Directors of the
     Company will immediately receive an initial grant of options to purchase
     2,500 shares of the Company (the "Initial Options"), and subsequent grants
     of options to purchase 1,000 shares of the Company on the date of each
     annual meeting of shareholders beginning with the 2000 Annual Meeting (the
     "Subsequent Options").  The Initial Options and the Subsequent Options are
     hereinafter collectively referred to as the "Options."  However, options
     may not be granted at any time when the grant, along with grants to other
     Independent Directors, would exceed 10% of the issued and outstanding
     Shares.  The option price for the Initial Options will be $12.00 per share.
     The option price for the Subsequent Options shall be the greater of (1)
     $12.00 per share or (2) the fair market value of the Shares as defined in
     Section 3.5 of the Plan.

          One-fifth of the Initial Options are exercisable beginning on the date
     of their grant and an additional one-fifth of the Initial Options will
     become exercisable on each anniversary of the date of their grant for a
     period of four years until 100% of the shares become exercisable.  The

                                       11
<PAGE>
 
     Subsequent Options granted under the Plan will become exercisable on the
     second anniversary of the date of their grant.

          A total of 100,000 shares have been authorized and reserved for
     issuance under the Plan.  If the number of outstanding shares is increased,
     decreased or changed into, or exchanged for, a different number or kind of
     shares or securities of the Company through a reorganization or merger in
     which the Company is the surviving entity, or through a combination,
     recapitalization, reclassification, stock split, stock dividend, stock
     consolidation or otherwise, an appropriate adjustment will be made in the
     number and kind of shares that may be issued pursuant to the Options.  A
     corresponding adjustment to the exercise price of the Options granted prior
     to any change will also be made.  Any such adjustment, however, will be
     made without change in the total payment, if any, applicable to the portion
     of the Options not exercised but with a corresponding adjustment in the
     exercise price for each share.

          Options granted under the Plan shall lapse on the first to occur of
     (1) the tenth anniversary of the date of grant, (2) the removal for cause
     of the Independent Director as a member of the Board of Directors, or (3)
     three months following the date the Independent Director ceases to be a
     Director for any reason other than death or disability, and may be
     exercised by payment of cash or through the delivery of common stock.
     Options granted under the Plan are generally exercisable in the case of
     death or disability for a period of one year after death or the disabling
     event.  No Option issued pursuant to the Plan may be exercised if such
     exercise would jeopardize the Company's status as a REIT under the Internal
     Revenue Code.

          No Option may be sold, pledged, assigned or transferred by an
     Independent Director in any manner otherwise than by will or the laws of
     descent or distribution.

          Upon the dissolution or liquidation of the Company or upon the
     reorganization, merger or consolidation with one or more corporations as a
     result of which the Company is not the surviving corporation or upon sale
     of all or substantially all of the properties, the Plan will terminate, and
     any outstanding Options will terminate and be forfeited.  Notwithstanding
     the foregoing, the Board of Directors may provide in writing in connection
     with, or in contemplation of, any such transaction for any or all of the
     following alternatives:  (1) for the assumption by the successor
     corporation of the Options granted or the substitution by such corporation
     for such Options of options covering the stock of the successor
     corporation, or a parent or subsidiary thereof, with appropriate
     adjustments as to the number and kind of shares and exercise prices; (2)
     for the continuance of the Plan by such successor corporation in which
     event the Plan and the Options will continue in the manner and under the
     terms so provided; or (3) for the payment in cash or shares of common stock
     in lieu of and in complete satisfaction of such Options.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATION

     The information contained on page 46 in the "Management's Discussion and
Analysis of Financial Condition and Results of Operations" section of the
Prospectus is revised as of the date of this Supplement by the deletion of the
first paragraph of that section and the insertion of the following paragraph in
lieu thereof:

          The Company commenced operations on June 5, 1998, upon the acceptance
     of subscriptions for the minimum offering of $1,250,000 (125,000 Shares).
     As of April 5, 1999, the Company had raised a total of $57,235,152 in
     offering proceeds (5,723,515 Shares), and had paid $2,003,230 in
     acquisition and advisory fees and acquisition expenses and $7,154,394 in
     selling commissions and organizational and offering expenses.  As of April
     5, 1999, the Company had invested $43,472,358 in properties and was holding
     net offering proceeds of $4,605,170 available for investment in additional
     properties.

                                       12
<PAGE>
 
     The following shall be added to the "Management's Discussion and Analysis
of Financial Condition and Result of Operations" section of the Prospectus:

     YEAR 2000 ISSUES

          The Company is presently reviewing the potential impact of Year 2000
     compliance issues on its information systems and business operations.  A
     full assessment of Year 2000 compliance issues was begun in late 1997 and
     was completed on March 31, 1999.  Renovations and replacements of equipment
     have been and are being made as warranted.  The costs incurred by the
     Company and its Affiliates thus far for renovations and replacements have
     been immaterial.  Some testing of systems has begun and all testing is
     expected to be complete by June 30, 1999.

          As to the status of the Company's information technology systems, it
     is presently believed that all major systems and software packages with the
     exception of the accounting and property management package are Year 2000
     compliant.  The Company's affiliated entities are purchasing the upgrade
     for the accounting and property management package system; however, it is
     not slated to be installed until second quarter 1999.  At the present time,
     it is believed that all major non-information technology systems are Year
     2000 compliant.  The cost to upgrade any non-compliant systems is believed
     to be immaterial.

          The Company is in the process of confirming with the Company's
     vendors, including third-party service providers such as banks, that their
     systems will be Year 2000 compliant.  Based on the information received
     thus far, the primary third-party service providers with which the Company
     has relationships have confirmed their Year 2000 readiness.

          The Company relies on computers and operating systems provided by
     equipment manufacturers, and also on application software designed for use
     with its accounting, property management and investment portfolio tracking.
     The Company has preliminarily determined that any costs, problems or
     uncertainties associated with the potential consequences of Year 2000
     issues are not expected to have a material impact on the future operations
     or financial condition of the Company.  The Company will perform due
     diligence as to the Year 2000 readiness of each property owned by the
     Company and each property contemplated for purchase by the Company.

          The Company's reliance on embedded computer systems (i.e.,
     microcontrollers) is limited to facilities related matters, such as office
     security systems and environmental control systems.

          The Company is currently formulating contingency plans to cover any
     areas of concern.  Alternate means of operating the business are being
     developed in the unlikely circumstance that the computer and phone systems
     are rendered inoperable.  An off-site facility from which the Company could
     operate is being sought as well as alternate means of communication with
     key third-party vendors.  A written plan is being developed for testing and
     dispensation to each staff member of the Advisor of the Company.

          Management believes that the Company's risk of Year 2000 problems is
     minimal.  In the unlikely event there is a problem, the worst case
     scenarios would include the risks that the elevator or security systems
     within the Company's properties would fail or the key third-party vendors
     upon which the Company relies would be unable to provide accurate investor
     information.  In the event that the elevator shuts down, the Company has
     devised a plan for each building whereby the tenants will use the stairs
     until the elevators are fixed.  In the event that the security system shuts
     down, the Company has devised a plan for each building to hire temporary
     on-site security guards.  In the event that a third-party vendor has Year
     2000 problems relating to investor information, the Company intends to
     perform a full system back-up of all investor information as of December
     31, 1999 so that the Company will have accurate hard-copy investor
     information.

     The information contained on page 77 in the "Plan of Distribution" section
of the Prospectus is revised as of the date of this Supplement by the addition
of the following paragraph after the second full paragraph on that page:

          Investors who wish to elect the Deferred Commission Option should make
     the election on their Subscription Agreement Signature Page, the revised
     form of which is included as Exhibit "B" to this Supplement.  Election of
     the Deferred Commission Option shall authorize the Company to withhold
     dividends or other cash distributions otherwise payable to such investor
     for the purpose of paying commissions due under the Deferred Commission
     Option.  Such dividends or cash distributions otherwise payable to
     investors may be pledged by the Company, the Dealer Manager, the Advisor or
     their Affiliates to secure one or more loans, the proceeds of which would
     be used to satisfy sales commission obligations.

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS



To Wells Real Estate Investment Trust, Inc.:

We have audited the accompanying consolidated balance sheets of WELLS REAL
ESTATE INVESTMENT TRUST, INC. (a Maryland corporation) AND SUBSIDIARY as of
December 31, 1998 and 1997 and the related consolidated statements of income,
shareholders' equity, and cash flows for the year ended December 31, 1998.
These financial statements and the schedule referred to below are the
responsibility of the Company's management.  Our responsibility is to express an
opinion on these financial statements and schedule based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and schedule are
free of material misstatement.  An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements.  An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation.  We believe that our audits provide a reasonable basis
for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Wells Real Estate Investment
Trust, Inc. and subsidiary as of December 31, 1998 and 1997 and the results of
their operations and their cash flows for the year ended December 31, 1998 in
conformity with generally accepted accounting principles.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


                          DECEMBER 31, 1998 AND 1997

1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

   Wells Real Estate Investment Trust, Inc. (the "Company") is a Maryland
   corporation that qualifies as a real estate investment trust ("REIT").  The
   Company is conducting an offering for the sale of a maximum of 15,000,000
   (exclusive of 1,500,000 shares available pursuant to the Company's dividend
   reinvestment plan) shares of common stock, $.01 par value per share, at a
   price of $10 per share.  During 1997, the Company sold 100 shares to Wells
   Capital, Inc. (the "Advisor") at the proposed initial public offering price
   of $10 per share.  The Company will seek to acquire and operate commercial
   properties, including, but not limited to, office buildings, shopping
   centers, business and industrial parks, and other commercial and industrial
   properties, including properties which are under construction, are newly
   constructed, or have been constructed and have operating histories.  All such
   properties may be acquired, developed, and operated by the Company alone or
   jointly with another party.  The Company is likely to enter into one or more
   joint ventures with affiliated entities for the acquisition of properties.
   In connection with this, the Company may enter into joint ventures for the
   acquisition of properties with prior or future real estate limited
   partnership programs sponsored by the Advisor or its affiliates.

   Substantially all of the Company's business is conducted through Wells
   Operating Partnership, L.P. (the "Operating Partnership"), a Delaware limited
   partnership.  During 1997, the Operating Partnership issued 20,000 limited
   partner units to the Advisor in exchange for $200,000.  The Company is the
   sole general partner in the Operating Partnership and possesses full legal
   control and authority over the operations of the Operating Partnership;
   consequently, the accompanying consolidated financial statements of the
   Company include the amounts of the Operating Partnership.

   The Company owns interests in several properties through a joint venture
   among the Operating Partnership, Wells Real Estate Fund IX, L.P. ("Wells Fund
   IX"), Wells Real Estate Fund X, L.P. ("Wells Fund X"), and Wells Real Estate
   Fund XI, L.P. ("Wells Fund XI").  This joint venture is referred to as the
   Fund IX, Fund X, Fund XI, and REIT Joint Venture ("Fund IX, X, XI, and REIT
   Joint Venture").  In addition, the Company owns two properties through joint
   ventures between the Operating Partnership and a joint venture between Wells
   Fund X and Wells Fund XI, referred to as "Fund X and XI Associates."  In
   addition, the Operating Partnership directly owns an office building in
   Tampa, Florida.

                                      I-6
<PAGE>
 
   Through its investment in the Fund IX, X, XI, and REIT Joint Venture, the
   Company owns interests in the following properties:  (i) a three-story office
   building in Knoxville, Tennessee (the "ABB Building"), (ii) a two-story
   office building in Louisville, Colorado (the "Ohmeda Building"), (iii) a
   three-story office building in Broomfield, Colorado (the "360 Interlocken
   Building"), (iv) a one-story warehouse facility in Ogden, Utah (the "Iomega
   Building"), and (v) a one-story office building in Oklahoma City, Oklahoma
   (the "Lucent Technologies Building").

   The following properties are owned by the Operating Partnership through
   investments in joint ventures with Fund X and XI Associates:  (i) a one-story
   office and warehouse building in Fountain Valley, California (the "Cort
   Furniture Building") owned by Wells/Orange County Associates and (ii) a
   warehouse and office building in Fremont, California (the "Fairchild
   Building") owned by Wells/Fremont Associates.

   USE OF ESTIMATES AND FACTORS AFFECTING THE COMPANY

   The preparation of the consolidated financial statements in conformity with
   generally accepted accounting principles requires management to make
   estimates and assumptions that affect the reported amounts of assets and
   liabilities and disclosure of contingent assets and liabilities at the date
   of the financial statements and the reported amounts of revenues and expenses
   during the reporting period.  Actual results could differ from those
   estimates.

   The carrying values of real estate are based on management's current intent
   to hold the real estate assets as long-term investments.  The success of the
   Company's future operations and the ability to realize the investment in its
   assets will be dependent on the Company's ability to maintain rental rates,
   occupancy, and an appropriate level of operating expenses in future years.
   Management believes that the steps it is taking will enable the Company to
   realize its investment in its assets.

   REAL ESTATE ASSETS

   Real estate assets held by the Company and joint ventures are stated at cost
   less accumulated depreciation.  Major improvements and betterments are
   capitalized when they extend the useful life of the related asset.  All
   repair and maintenance are expensed as incurred.

   Management continually monitors events and changes in circumstances which
   could indicate that carrying amounts of real estate assets may not be
   recoverable.  When events or changes in circumstances are present which
   indicate that the carrying amounts of real estate assets may not be
   recoverable, management assesses the recoverability of real estate assets by
   determining whether the carrying value of such real estate assets will be
   recovered through the future cash flows expected from the use of the asset
   and its eventual disposition.  Management has determined that there has been
   no impairment in the carrying value of real estate assets held by the Company
   or the joint ventures as of December 31, 1998.

                                      I-7
<PAGE>
 
   Depreciation of building and improvements is calculated using the straight-
   line method over 25 years.  Tenant improvements are amortized over the life
   of the related lease or the life of the asset, whichever is shorter.

   INVESTMENT IN JOINT VENTURES

   The Operating Partnership does not have control over the operations of the
   joint ventures; however, it does exercise significant influence.
   Accordingly, the Operating Partnership's investment in the joint ventures is
   recorded using the equity method of accounting.

   REVENUE RECOGNITION

   All leases on real estate assets held by the Company or the joint ventures
   are classified as operating leases, and the related rental income is
   recognized on a straight-line basis over the terms of the respective leases.

   DEFERRED LEASE ACQUISITION COSTS

   Costs incurred to procure operating leases are capitalized and amortized on a
   straight-line basis over the terms of the related leases.

   CASH AND CASH EQUIVALENTS

   For the purposes of the statement of cash flows, the Company considers all
   highly liquid investments purchased with an original maturity of three months
   or less to be cash equivalents.  Cash equivalents include cash and short-term
   investments.  Short-term investments are stated at cost, which approximates
   fair value, and consist of investments in money market accounts.

2. DEFERRED PROJECT COSTS

   The Company paid a percentage of shareholder contributions to the Advisor for
   acquisition and advisory services.  These payments, as stipulated in the
   prospectus, can be up to 3.5% of shareholder contributions, subject to
   certain overall limitations contained in the prospectus.  Aggregate fees paid
   through December 31, 1998 were $1,103,913 and amounted to 3.5% of
   shareholders' contributions received.  These fees are allocated to specific
   properties as they are purchased or developed and are included in capitalized
   assets of the joint ventures or real estate assets.  Deferred project costs
   at December 31, 1998 represent fees not yet applied to properties.

3. DEFERRED OFFERING COSTS

   Organization and offering expenses, to the extent they exceed 3% of gross
   proceeds, will be paid by the Advisor and not by the Company.  Organization
   and offering expenses do not include sales or underwriting commissions but do
   include such costs as legal and accounting fees, printing costs, and other
   offering expenses.

4. RELATED-PARTY TRANSACTIONS

   Due from affiliates at December 31, 1998 represents the Operating
   Partnership's share of the cash to be distributed for the fourth quarter of
   1998 as follows:


       Fund IX, X, XI, and REIT Joint Venture       $ 38,360
       Wells/Orange County Associates                 77,123
       Wells/Fremont Associates                      146,862
                                                    -------- 
                                                    $262,345 
                                                    -------- 


   The Company entered into a property management agreement with Wells
   Management Company, Inc. ("Wells Management"), an affiliate of the Advisor.
   In consideration for supervising the management and leasing of the Operating
   Partnership's properties, the Operating Partnership will pay Wells Management
   management and leasing fees equal to the lesser of (a) fees that would be
   paid to a comparable outside firm, or (b) 4.5% of the gross revenues
   generally paid over the life of the lease plus a separate competitive fee for
   the one-time initial lease-up of newly constructed properties generally paid
   in conjunction with the receipt of the first month's rent.  In the case of
   commercial properties which are leased on a long-term (ten or more years) net
   lease basis, the maximum property management fee from such leases shall be 1%
   of the gross revenues generally paid over the life of the leases except for a
   one-time initial leasing fee of 3% of the gross revenues on each lease
   payable over the first five full years of the original lease term.

   The Operating Partnership's portion of the management and leasing fees and
   lease acquisition costs paid to Wells Management by the joint ventures was
   $5,673 for the year ended December 31, 1998.

   The Advisor performs certain administrative services for the Operating
   Partnership, such as accounting and other partnership administration, and
   incurs the related expenses.  Such expenses are allocated among the Operating
   Partnership and the various Wells Real Estate Funds based on time spent on
   each fund by individual administrative personnel.  In the opinion of
   management, such allocation is a reasonable basis for allocating such
   expenses.

   The Advisor is a general partner in various Wells Real Estate Funds.  As
   such, there may exist conflicts of interest where the Advisor, while serving
   in the capacity as general partner for Wells Real Estate Funds, may be in
   competition with the Operating Partnership for tenants in similar geographic
   markets.

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS





To Wells Real Estate Investment Trust, Inc.:


We have audited the accompanying statement of revenues over certain operating
expenses for the VANGUARD CELLULAR BUILDING for the period from inception
(November 16, 1998) to December 31, 1998. This financial statement is the
responsibility of management. Our responsibility is to express an opinion on
this financial statement based on our audit.

We conducted our audit in accordance with generally accepted auditing standards.
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the statement of revenues over certain operating
expenses is free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the statement of
revenues over certain operating expenses. An audit also includes assessing the
accounting principles used and significant estimates made by management, as well
as evaluating the overall financial statement presentation. We believe that our
audit provides a reasonable basis for our opinion.

As described in Note 2, this financial statement excludes certain expenses that
would not be comparable with those resulting from the operations of the Vanguard
Cellular Building after acquisition by Wells Operating Partnership, L.P. (on
behalf of Wells Real Estate Investment Trust, Inc.). The accompanying statement
of revenues over certain operating expenses was prepared for the purpose of
complying with the rules and regulations of the Securities and Exchange
Commission and is not intended to be a complete presentation of the Vanguard
Cellular Building's revenues and expenses.

In our opinion, the statement of revenues over certain operating expenses
presents fairly, in all material respects, the revenues over certain operating
expenses of the Vanguard Cellular Building for the period from inception
(November 16, 1998) to December 31, 1998 in conformity with generally accepted
accounting principles.

  1.  ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

      DESCRIPTION OF REAL ESTATE PROPERTY ACQUIRED

      On February 4, 1999, Wells Operating Partnership, L.P. ("Wells OP"), a
      Delaware limited partnership, formed to acquire and hold real estate
      properties on behalf of Wells Real Estate Investment Trust, Inc. (the
      "Registrant"), acquired a four-story office building (the "Vanguard
      Cellular Building") containing approximately 81,859 rentable square feet,
      for the price of $12,291,200 plus acquisition expenses, including legal
      fees, of approximately $240,900. Wells OP paid $6,382,100 in cash and
      obtained a loan in the amount of $6,450,000 from NationsBank, N. A. (the
      "NationsBank Loan"). As of February 4, 1999, $6,150,000 was outstanding on
      the NationsBank Loan. The NationsBank Loan gives Wells OP the option of
      extending the term of the loan after the initial six months. The interest
      rate for the initial six months of the NationsBank Loan is fixed at 7%. On
      August 1, 1999, Wells OP may extend the NationsBank Loan at a rate of
      LIBOR plus 200 basis points for up to 29 additional months. During the
      term of the extension, Wells OP is required to make quarterly principal
      installments in an amount equal to one-ninth of the outstanding principal
      balance as of October 1, 1999. The NationsBank Loan is secured by a first
      mortgage against the Vanguard Cellular Building. Legal fees, loan
      origination costs, and appraisal fees incurred from obtaining the
      NationsBank Loan totaled approximately $29,000.

      The Vanguard Cellular Building is 100% occupied by one tenant with a ten-
      year lease term that commenced on November 16, 1998 and expires on
      November 15, 2008. Construction of the building was completed in November
      1998. Under the terms of the lease agreement, monthly base rent payable is
      subject to escalations of 2% per annum and certain lease inception
      discounts. The lease is a triple net lease, whereby the terms require the
      tenant to reimburse Wells OP for certain operating expenses, as defined in
      the lease, related to the building. All of the operating expenses for the
      period from lease inception (November 16, 1998) to December 31, 1998 have
      been passed through to the tenant.

      RENTAL REVENUES

      Rental income from the lease is recognized on a straight-line basis over
      the life of the lease.

      statement excludes certain historical expenses, such as interest,
      depreciation, and management fees, not comparable to the operations of the

                           PRIOR PERFORMANCE TABLES

     The following Prior Performance Tables (the "Tables") provide information
relating to real estate investment programs sponsored by the Advisor and its
Affiliates ("Wells Prior Public Programs") which have investment objectives
substantially similar to the Company. The Company's investment objectives are to
maximize Net Cash From Operations; to preserve original Capital Contributions;
and to realize capital appreciation over a period of time. (See "Investment
Objectives and Criteria.") All of the Wells Prior Public Programs, except for
the Company, have used a substantial amount of capital, and no acquisition
indebtedness, to acquire their properties.

     Prospective investors should read these Tables carefully together with the
summary information concerning the Wells Prior Public Programs as set forth in
the "Prior Performance Summary" section of this Prospectus.

     Investors in the Company will not own any interest in the other Wells Prior
Public Programs and should not assume that they will experience returns, if any,
comparable to those experienced by investors in the Wells Prior Public Programs.

     The Advisor is responsible for the acquisition, operation, maintenance and
resale of the real estate properties. The financial results of the Wells Prior
Public Programs thus provide an indication of the Advisor's performance of its
obligations during the periods covered. However, general economic conditions
affecting the real estate industry and other factors contribute significantly to
financial results.

     The following tables are included in this Supplement to the Prospectus:

     TABLE I - Experience in Raising and Investing Funds (As a Percentage of
Investment)

     TABLE II - Compensation to Sponsor (in Dollars)

     TABLE III - Annual Operating Results of Wells Prior Public Programs

     TABLE IV (Results of completed programs) and TABLE V (sales or disposals of
property) have been omitted since none of the Wells Prior Public Programs have
sold any of their properties to date.

     Additional information relating to the acquisition of properties by the
Wells Prior Public Programs is contained in TABLE VI, which is included in Part
II of the registration statement which the Company has filed with the Securities
and Exchange Commission.  As described above, no Wells Prior Public Program has
sold or disposed of any property held by it.  Copies of any or all information
will be provided to prospective investors at no charge upon request.

     The following are definitions of certain terms used in the Tables:

     "ACQUISITION FEES" shall mean fees and commissions paid by a partnership in
connection with its purchase or development of a property, except development
fees paid to a person not affiliated with the partnership or with a general
partner of the partnership in connection with the actual development of a
project after acquisition of the land by the partnership.

     "ORGANIZATION EXPENSES" shall include legal fees, accounting fees,
securities filing fees, printing and reproduction expenses and fees paid to the
general partners or their affiliates in connection with the planning and
formation of the partnership.

     "UNDERWRITING FEES" shall include selling commissions and wholesaling fees
paid to broker-dealers for services provided by the broker-dealers during the
offering.

to residents of the States of New York and Pennsylvania, whose payments for
Shares will be held in escrow until the Company has received and accepted
subscriptions for 250,000 Shares ($2,500,000) from all investors.

     I hereby acknowledge receipt of the Prospectus of the Company dated January

from the Company for serving as a Director or officer other than reasonable
reimbursement for travel and related expenses incurred in attending meetings of
the Directors.

     (9)  FEES.

     (a)  Acquisition Fees. The Advisor may receive as compensation for services
rendered in connection with the investigation, selection and acquisition (by
purchase, investment or exchange) of Property an Acquisition Fee payable by the
Company. The Acquisition Fees shall be reduced to the extent that, and, if
necessary to limit, the total compensation paid to all persons involved in the
acquisition of any Property to the amount customarily charged in arm's-length
transactions by other persons or entities rendering similar services as an
ongoing public activity in the same geographical location and for comparable
types of Properties and to the extent that other acquisition fees, finder's
fees, real estate commissions, or other similar fees or commissions are paid by
any person in connection with the transaction.

     (b)  Subordinated Disposition Fee. If the Advisor or an Affiliate provides
a substantial amount of the services (as determined by a majority of the
Independent Directors) in connection with the Sale of one or more Properties,
the Advisor or an Affiliate shall receive a Subordinated Disposition Fee equal
to the lesser of (i) one-half of a Competitive Real Estate Commission or (ii) 3%
of the sales price of such Property or Properties. The Subordinated Disposition
Fee will be paid only if Stockholders have received total Distributions in an
amount equal to the sum of their aggregate Invested Capital and their aggregate
Stockholders' 8% Return. To the extent that Subordinated Disposition Fees are
not paid by the Company on a current basis due to the foregoing limitation, the
unpaid fees will be accrued and paid at such time as the subordination
conditions have been satisfied. The Subordinated Disposition Fee may be paid in
addition to real estate commissions paid to non-Affiliates, provided that the
total real estate commissions paid to all Persons by the Company shall not
exceed an amount equal to the lesser of (i) 6% of the Contract Sales Price of a
Property or (ii) the Competitive Real Estate Commission. In the event this
Agreement is terminated prior to such time as the Stockholders have received
total Distributions in an amount equal to 100% of Invested Capital plus an
amount sufficient to pay the Stockholders' 8% Return through the Termination
Date, an appraisal of the Properties then owned by the Company shall be made and
the Subordinated Disposition Fee on Properties previously sold will be deemed
earned if the Appraised Value of the Properties then owned by the Company plus
total Distributions received prior to the Termination Date equals 100% of
Invested Capital plus an amount sufficient to pay the Stockholders' 8% Return
through the Termination Date. Upon Listing, if the Advisor has accrued but not
been paid such Subordinated Disposition Fee, then for purposes of determining
whether the subordination conditions have been satisfied, Stockholders will be
deemed to have received a Distribution in the amount equal to the product of the
total number of Shares outstanding and the average closing price of the Shares
over a period, beginning 180 days after Listing, of 30 days during which the
Shares are traded.

                                      -12-
<PAGE>
 
     (c)  Subordinated Share of Net Sales Proceeds. The Subordinated Share of
Net Sales Proceeds shall be payable to the Advisor in an amount equal to 10% of
Net Sales Proceeds remaining after the Stockholders have received Distributions
equal to the sum of the Stockholders' 8% Return and 100% of Invested Capital.
Following Listing, no Subordinated Share of Net Sales Proceeds will be paid to
the Advisor. In the event the fee set forth in this section is paid to the
Advisor, no Net Sales Proceeds will be paid to the Advisor.

     (d)  Subordinated Incentive Fee. Upon Listing, the Advisor shall be paid
the Subordinated Incentive fee in an amount equal to 10% of the amount by which
(i) the market value of the Company, measured by taking the average closing
price or average of bid and asked price, as the case may be, over a period of 30
days during which the Shares are traded, with such period beginning 180 days
after Listing (the "Market Value"), plus the total Distributions paid to
Stockholders from the Company's inception until the date of Listing, exceeds
(ii) the sum of (A) 100% of Invested Capital and (B) the total Distributions
required to be paid to the Stockholders in order to pay the Stockholders' 8%
Return from inception through the date the Market Value is determined. The
Company shall have the option to pay such fee in the form of cash, Shares, a
promissory note or any combination of the foregoing. The Subordinated Incentive
Fee will be reduced by the amount of any prior payment to the Advisor of a
deferred, subordinated share of Net Sales Proceeds from a Sale or Sales of a
Property. In the event the Subordinated Incentive Fee is paid to the Advisor
following Listing, no other performance fee will be paid to the Advisor. In the
event the Subordinated Incentive Fee is paid to the Advisor following Listing,
no other performance fee will be paid to the Advisor.

     (e)  Loans from Affiliates. If any loans are made to the Company by an
Affiliate of the Advisor, the maximum amount of interest that may be charged by
such Affiliate shall be the lesser of (i) 1% above the prime rate of interest
charged from time to time by [The Bank of New York] and (ii) the rate that would
be charged to the Company by unrelated lending institutions on comparable loans
for the same purpose. The terms of any such loans shall be no less favorable
than the terms available between non-Affiliated Persons for similar commercial
loans.

     (f)  Changes to Fee Structure. In the event of Listing, the Company and the
Advisor shall negotiate in good faith to establish a fee structure appropriate
for a perpetual-life entity. A majority of the Independent Directors must
approve the new fee structure negotiated with the Advisor. In negotiating a new
fee structure, the Independent Directors shall consider all of the factors they
deem relevant, including, but not limited to: (i) the amount of the advisory fee
in relation to the asset value, composition and profitability of the Company's
portfolio; (ii) the success of the Advisor in generating opportunities that meet
the investment objectives of the Company; (iii) the rates charged to other REITs
and to investors other than REITs by Advisors performing the same or similar
services; (iv) additional revenues realized by the Advisor and its Affiliates
through their relationship with the Company, including loan administration,
underwriting or broker commissions, servicing, engineering, inspection and other
fees, whether paid by the REIT or by others with whom the REIT does business;
(v) the quality and extent of service and advice furnished by the Advisor; (vi)
the performance of the investment portfolio of the REIT, including income,
conversion or appreciation of capital, and number and frequency of problem
investments; and (vii) the quality of the Property portfolio of the Company in

                                      -13-
<PAGE>
 
relationship to the investments generated by the Advisor for its own account.
The new fee structure can be no more favorable to the Advisor than the current
fee structure.

     (b)  Expenses incurred by the Advisor on behalf of the Company and payable
pursuant to this Paragraph 10 shall be reimbursed no less than monthly to the
Advisor. The Advisor shall prepare a statement documenting the expenses of the
Company during each quarter, and shall deliver such statement to the Company
within 45 days after the end of each quarter.

     (11) OTHER SERVICES. Should the Directors request that the Advisor or any
director, officer or employee thereof render services for the Company other than
set forth in Paragraph 3, such services shall be separately compensated at such
rates and in such amounts as are agreed by the Advisor and the Independent
Directors of the Company, subject to the limitations contained in the Articles
of Incorporation, and shall not be deemed to be services pursuant to the terms
of this Agreement.

     (12) FIDELITY BOND. The Advisor shall maintain a fidelity bond for the
benefit of the Company which bond shall insure the Company from losses of up to
$200,000 per occurrence and shall be of the type customarily purchased by
entities performing services similar to those provided to the Company by the
Advisor.

     (13) REIMBURSEMENT TO THE ADVISOR. The Company shall not reimburse the
Advisor at the end of any fiscal quarter Operating Expenses that, in the four
consecutive fiscal quarters then ended (the "Expense Year") exceed (the "Excess
Amount") the greater of 2% of Average Invested Assets or 25% of Net Income (the
"2%/25% Guidelines") for such year. Any Excess Amount paid to the Advisor during
a fiscal quarter shall be repaid to the Company. If there is an Excess Amount in
any Expense Year and the Independent Directors determine that such excess was
justified, based on unusual and nonrecurring factors which they deem sufficient,
the Excess Amount may be carried over and included in Operating Expenses in
subsequent Expense Years, and reimbursed to the Advisor in one or more of such
years, provided that Operating Expenses in any Expense Year, including any
Excess Amount to be paid to the Advisor, shall not exceed the 2%/25% Guidelines.
Within 60 days after the end of any fiscal quarter of the Company for which
total Operating Expenses for the Expense Year exceed the 2%/25% Guidelines,
there shall be sent to the stockholders a written disclosure of such fact,
together with an explanation of the factors the Independent Directors considered
in determining that such excess expenses were justified. Such determination
shall be reflected in the minutes of the meetings of the Board of Directors. The
Company will not reimburse the Advisor or its Affiliates for services for which
the Advisor or its Affiliates are entitled to compensation in the

                                      -15-
<PAGE>
 
form of a separate fee. All figures used in the foregoing computation shall be
determined in accordance with generally accepted accounting principles applied
on a consistent basis.

     (14) OTHER ACTIVITIES OF THE ADVISOR. Nothing herein contained shall
prevent the Advisor from engaging in other activities, including, without
limitation, the rendering of advice to other Persons (including other REITs) and
the management of other programs advised, sponsored or organized by the Advisor
or its Affiliates; nor shall this Agreement limit or restrict the right of any
director, officer, employee, or stockholder of the Advisor or its Affiliates to
engage in any other business or to render services of any kind to any other
partnership, corporation, firm, individual, trust or association. The Advisor
may, with respect to any investment in which the Company is a participant, also
render advice and service to each and every other participant therein. The
Advisor shall report to the Directors the existence of any condition or
circumstance, existing or anticipated, of which it has knowledge, which creates
or could create a conflict of interest between the Advisor's obligations to the
Company and its obligations to or its interest in any other partnership,
corporation, firm, individual, trust or association. The Advisor or its
Affiliates shall promptly disclose to the Directors knowledge of such condition
or circumstance. If the Sponsor, Advisor, Director or Affiliates thereof have
sponsored other investment programs with similar investment objectives which
have investment funds available at the same time as the Company, it shall be the
duty of the Directors (including the Independent Directors) to adopt the method
set forth in the Registration Statement or another reasonable method by which
properties are to be allocated to the competing investment entities and to use
their best efforts to apply such method fairly to the Company.

     The Advisor shall be required to use its best efforts to present a
continuing and suitable investment program to the Company which is consistent
with the investment policies and objectives of the Company, but neither the
Advisor nor any Affiliate of the Advisor shall be obligated generally to present
any particular investment opportunity to the Company even if the opportunity is
of character which, if presented to the Company, could be taken by the Company.
The Advisor or its Affiliates may make such an investment in a property only
after (i) such investment has been offered to the Company and all public
partnerships and other investment entities affiliated with the Company with
funds available for such investment and (ii) such investment is found to be
unsuitable for investment by the Company, such partnerships and investment
entities.

     In the event that the Advisor or its Affiliates is presented with a
potential investment which might be made by the Company and by another
investment entity which the Advisor or its Affiliates advises or manages, the
Advisor shall consider the investment portfolio of each entity, cash flow of
each entity, the effect of the acquisition on the diversification of each
entity's portfolio, rental payments during any renewal period, the estimated
income tax effects of the purchase on each entity, the policies of each entity
relating to leverage, the funds of each entity available for investment and the
length of time such funds have been available for investment. In the event that
an investment opportunity becomes available which is suitable for both the
Company and a public or private entity which the Advisor or its Affiliates are
Affiliated, then the entity which has had the longest period of time elapse
since it was offered an investment opportunity will first be offered the
investment opportunity. The Advisor may consider the

                                      -16-
<PAGE>
 
property for private placement only if such property is deemed inappropriate for
any investment entity which is advised or managed by the Advisor, including the
Company.

     (15) RELATIONSHIP OF ADVISOR AND COMPANY. The Company and the Advisor are
not partners or joint venturers with each other, and nothing in this Agreement
shall be construed to make them such partners or joint venturers or impose any
liability as such on either of them.

     (16) TERM; TERMINATION OF AGREEMENT. This Agreement shall continue in force
until January 30, 2000, subject to an unlimited number of successive one-year
renewals upon mutual consent of the parties. It is the duty of the Directors to
evaluate the performance of the Advisor or annually before renewing the
Agreement, and each such renewal shall be for a term of no more than one year.

     (17) TERMINATION BY EITHER PARTY. This Agreement may be terminated upon 60
days written notice without Cause or penalty, by either party (by a majority of
the Independent Directors of the Company or a majority of the Board of Directors
of the Advisor, as the case may be).

     (18) ASSIGNMENT TO AN AFFILIATE. This Agreement may be assigned by the
Advisor to an Affiliate with the approval of a majority of the Directors
(including a majority of the Independent Directors). The Advisor may assign any
rights to receive fees or other payments under this Agreement without obtaining
the approval of the Directors. This Agreement shall not be assigned by the
Company without the consent of the Advisor, except in the case of an assignment
by the Company to a corporation or other organization which is a successor to
all of the assets, rights and obligations of the Company, in which case such
successor organization shall be bound hereunder and by the terms of said
assignment in the same manner as the Company is bound by this Agreement.

     (19) PAYMENTS TO AND DUTIES OF ADVISOR UPON TERMINATION. Payments to the
Advisor pursuant to this Section (19) shall be subject to the 2%/25% Guidelines
to the extent applicable.

     (a)  After the Termination Date, the Advisor shall not be entitled to
compensation for further services hereunder except it shall be entitled to
receive from the Company within 30 days after the effective date of such
termination all unpaid reimbursements of expenses and all earned but unpaid fees
payable to the Advisor prior to termination of this Agreement.

     (b)  The Advisor shall promptly upon termination:

     (i)       pay over to the Company all money collected and held for the
account of the Company pursuant to this Agreement, after deducting any accrued
compensation and reimbursement for its expenses to which it is then entitled;

     (ii)      deliver to the Directors a full accounting, including a statement
showing all payments collected by it and a statement of all money held by it,
covering the period following the date of the last accounting furnished to the
Directors;

                                      -17-
<PAGE>
 
     (iii)     deliver to the Directors all assets, including Properties, and
documents of the Company then in the custody of the Advisor; and

     (iv)      cooperate with the Company to provide an orderly management
transition.

     (20) INDEMNIFICATION BY THE COMPANY. The Company shall indemnify and hold
harmless the Advisor and its Affiliates, including their respective officers,
directors, partners and employees, from all liability, claims, damages or losses
arising in the performance of their duties hereunder, and related expenses,
including reasonable attorneys' fees, to the extent such liability, claims,
damages or losses and related expenses are not fully reimbursed by insurance,
subject to any limitations imposed by the laws of the State of Maryland or the
Articles of Incorporation of the Company. Notwithstanding the foregoing, the
Advisor shall not be entitled to indemnification or be held harmless pursuant to
this paragraph 20 for any activity which the Advisor shall be required to
indemnify or hold harmless the Company pursuant to paragraph 21. Any
indemnification of the Advisor may be made only out of the net assets of the
Company and not from Stockholders.

     (21) INDEMNIFICATION BY ADVISOR. The Advisor shall indemnify and hold
harmless the Company from contract or other liability, claims, damages, taxes or
losses and related expenses including attorneys' fees, to the extent that such
liability, claims, damages, taxes or losses and related expenses are not fully
reimbursed by insurance and are incurred by reason of the Advisor's bad faith,
fraud, willful misfeasance, misconduct, negligence or reckless disregard of its
duties, but the Advisor shall not be held responsible for any action of the
Board of Directors in following or declining to follow any advice or
recommendation given by the Advisor.

     (22) NOTICES. Any notice, report or other communication required or
permitted to be given hereunder shall be in writing unless some other method of
giving such notice, report or other communication is required by the Articles of
Incorporation, the Bylaws, or accepted by the party to whom it is given, and
shall be given by being delivered by hand or by overnight mail or other
overnight delivery service to the addresses set forth herein:

restrictions included above shall not apply to any Shares acquired by the
Advisor or its Affiliates other than the Shares acquired through the Initial
Investment. The Advisor shall not vote any Shares it now owns, or hereafter
acquires, in any vote for the election of Directors or any vote regarding the
approval or termination of any contract with the Advisor or any of its
Affiliates.

intend to satisfy or cure; provided, however, Seller hereby agrees that Seller
shall satisfy or cure any such defects or objections consisting of taxes,
assessments, mortgages (including the Existing Loan Documents), deeds of trust,
mechanic's or materialmen's liens or monetary encumbrances willfully caused by
Seller. In the event Seller fails to give such written advice to Purchaser
within such ten (10) day period, Seller shall be deemed to have agreed to
satisfy or cure all such defects or objections set forth in Purchaser's notice.
Seller shall have until Closing to satisfy or cure all such defects and
objections which Seller agreed (or is deemed to have agreed) to satisfy or cure
as provided above. In the event there exist defects or objections which are not
required herein to be satisfied or cured by Seller

prior to Closing or in the event Seller fails or refuses to cure any defects
and objections which are required herein to be satisfied or cured by Seller
prior to the Closing, then, at the option of Purchaser, (i) Purchaser may
terminate this Agreement by written notice to Seller and Escrow Agent, in which
event the Earnest Money shall be immediately refunded to Purchaser, and this
Agreement shall be deemed of no force and effect and Purchaser and Seller shall
have no further rights, obligations or liabilities hereunder, except as
expressly provided herein, (ii) if any such defect or objection is one that
Seller agreed (or is deemed to have agreed) to satisfy or cure as provided
above, Purchaser may cure such defect or objection, in which event the Purchase
Price payable pursuant to Paragraph 4 hereof shall be reduced by an amount equal
to the actual cost and expense incurred by Purchaser in connection with the
curing of such defect or objection, (iii) Purchaser may accept title to the
Property subject to such defects and objections, or (iv) any combination of
items (ii) and (iii). In the event Purchaser elects to cure any such defects and
objections pursuant to item (ii) hereof, Purchaser at its option, upon giving
notice to Seller, may extend the date of Closing until the curing of such
defects or objections or thirty (30) days from and after the previously
scheduled date of Closing, whichever shall first occur. If any defect or
objection shall not have been cured within such period, Purchaser may exercise
its option under either item (i) or (iii) hereof. Purchaser and Seller agree
that if mechanic's or materialmen's liens in the aggregate amount of less than
$150,000.00 shall exist, in lieu of Seller satisfying such liens as required
above, Seller may elect to cause the Title Company to provide affirmative
insurance coverage to Purchaser with respect to such liens in Purchaser's
owner's title insurance policy issued to Purchaser at Closing, and any
incremental cost of providing such affirmative insurance coverage shall be paid
by Seller at Closing.

     From time to time, Purchaser may request an update to the effective date of
the Title Commitment and give notice to Seller of all defects or objections
appearing subsequent to the effective date of the Title Commitment (or previous
update thereof).

          (a)  Lease. Seller has delivered to Purchaser a complete and accurate 
               -----

     beneficial title to the Lease and the rents and other income thereunder
     subject only to the Existing Loan Documents.

          (b)  Lease - Assignment. To the best of Seller's knowledge, the Tenant
               ------------------                                             
     has not assigned its interest in its Lease or sublet any portion of the
     premises leased to such Tenant under its Lease.

          (c)  Lease - Default. (i) Seller has not received any notice of 
               ---------------                                            
     termination or default under the Lease, (ii) to the best of Seller's
     knowledge, there are no existing or uncured defaults by Seller or by the
     Tenant under the Lease, (iii) to the best of Seller's knowledge, there are
     no events which with passage of time or notice, or both, would constitute a
     default by Seller or by the Tenant under the Lease, and to the best of

                                       11
<PAGE>
 
     Seller's knowledge Seller has complied with each and every undertaking,
     covenant, and obligation of Seller under the Lease required to be complied
     with and/or performed as of the date this representation is made or
     reaffirmed, as the case may be, (iv) the Tenant has not asserted any
     defense, set-off, or counterclaim with respect to its tenancy or its
     obligation to pay rent, additional rent, or other charges pursuant to its
     Lease, and (v) neither Seller nor the Tenant has the right to terminate the
     Lease pursuant to Section 1.5 thereof. Further, Tenant has not indicated to
     Seller either orally or in writing its request or its intent to terminate
     its Lease prior to the expiration of the term of the Lease or to reduce the
     size of the premises leased by the Tenant.

          (d)  Lease - Rents and Special Consideration. Except as expressly 
               ---------------------------------------                      
     set forth in the Lease, the Tenant: (i) has not prepaid any rent under the
     Lease, (ii) is not entitled to receive any rent concession in connection
     with its tenancy under its Lease, and (iii) does not have any option or
     other evidence of any right or interest in or to the Property. The sums
     required to be paid by Seller to the Tenant under Section 2.1 of the Lease
     were paid in full by Seller to the Tenant prior to delinquency.

          (e)  Lease - Commissions.  No rental, lease, or other commissions with
               -------------------                                              
     respect to the Lease is payable to Seller or any party affiliated with or
     related to Seller or will be payable to Seller or any party affiliated with
     or related to Seller in connection with any renewal or extension of the
     Lease or any expansion of the premises leased by the Tenant. The only
     commission obligation of Seller with respect to the Lease is set forth in
     the commission agreement between Seller and Leasing Agents dated September
     19, 1997, accepted September 22, 1997, a true and complete copy of which
     has been provided to Purchaser. Seller has heretofore paid to Leasing
     Agents $270,000.00 of the commission payable to Leasing Agents under the
     aforesaid commission agreement and the remaining balance of such commission
     ($270,000.00) shall be due and payable to Leasing Agents as provided in the
     aforesaid commission agreement, and shall be paid by Seller at or prior to
     Closing. Except for the remaining $270,000.00 of the total commission in
     the amount of $540,000.00 payable by Seller to Leasing Agents as provided
     in the aforesaid commission agreement, and except as otherwise expressly
     provided in such commission agreement, no commission obligations currently
     exist with respect to the Lease or will accrue in the future with respect
     to the Lease arising out of the acts or agreements of Seller, including any
     such commission obligations which may result in the future from the
     exercise by the Tenant thereunder of any right or option in the Lease to
     extend the term of such Lease or to expand the space leased thereunder.
     Seller shall and does hereby indemnify and hold harmless Purchaser from and
     against any claim, whether or not meritorious, for any real estate
     commission, finder's fee, or like compensation in connection with the Lease
     or in connection with the exercise by Tenant thereunder of any right or
     option in the Lease to extend the term of such Lease or to expand the space
     leased thereunder arising out of any act or agreement by Seller, excepting
     only such claim by Leasing Agents under the aforesaid commission agreement.

          (f)  Intentionally Omitted.

     their respective provisions, (ii) all payments required to be made by
     Seller or the "Owner" thereunder have been paid in full, and (iii) there is

     party to any of such Service Contracts. All such Service Contracts are
     terminable without penalty or obligation to pay any severance or similar
     compensation on no more than thirty (30) days' notice. Seller agrees to
     cancel, effective no later than the Closing, any of the Service Contracts
     specified by Purchaser in a written notice to Seller given at least thirty
     (30) days prior to the Closing. To the best of Seller's knowledge, all
     Service Contracts are assignable by Seller to Purchaser and no Service
     Contract prohibits such assignment or provides for any right, claim, or
     cause of action against Purchaser or the Property upon such assignment.
     Seller has canceled or will cancel, effective as of the Closing, any
     agreement in the nature of a management agreement or service contract

     entity whatsoever any right, title, interest or benefit in or to all or any
     part of the Property, any rights to acquire all or any part of the Property
     or any rights relating to the development, use, operation, management,
     maintenance, or repair of all or any part of the Property.

          (j)  No Litigation. There are no actions, suits, or proceedings

               -----                                                    
     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 rent or other sums (not including security deposits) 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 total sum of all security deposits
     paid by the Tenant under the Lease and not theretofore applied to
     delinquent rent and other charges payable by the Tenant. 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) the 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 such
     Tenant, such Tenant is, or after application of a portion of such payment
     will be, current under the 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 owning it from such 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.  Unless the Tenant is obligated under the Lease
               --------------                                                 
     to pay the same directly to the taxing authority (and not to the Landlord
     under the Lease), city, state, county, and school district ad valorem taxes
     based on the ad valorem tax bills for the Property, if then available, or
     if not, then on the basis of the latest available tax figures and
     information. Should such proration be based on such latest available tax
     figures and information and prove to be inaccurate on receipt of the ad
     valorem tax bills for the Property for the year of Closing, either Seller
     or Purchaser, as the case may be, may demand at any time after Closing a
     payment from the other correcting such malapportionment. In addition, if
     after Closing there is an adjustment or reassessment by any governmental
     authority with respect to, or affecting, any ad valorem taxes for the
     Property for the year of Closing or any prior year, any additional tax
     payment for the Property required to be paid with respect the year of
     Closing shall be prorated between Purchaser and Seller and any such
     additional tax payment for the Property for any year prior to the year of
     Closing shall be paid by Seller. This agreement shall expressly survive the
     Closing.

                                       23

          (c)  Utility Charges. Seller shall pay or cause to be paid all 
               ---------------                                           
     utility bills received prior to Closing and shall be responsible for
     utilities furnished to the Property prior to Closing. Purchaser shall be
     responsible for the payment of all bills for utilities furnished to the
     Property subsequent to the Closing. Except to the extent that payment for
     utility services directly to the utility supplier is the responsibility of
     the Tenant under this Lease, 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), which agreement shall
     survive Closing. Seller shall be entitled to all deposits presently in
     effect with the utility providers.

          (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 the Tenant's
               --------------------                                        
      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 the 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.

      16.  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 receive
the Earnest Money as liquidated damages and thereafter the parties hereto shall
have no further rights or obligations hereunder whatsoever except for
obligations which expressly survive the termination of this Agreement. 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 prior to Closing, Seller shall not initiate any
proceeding to recover damages from Purchaser, but shall limit its recovery to
the receipt and retention of the Earnest Money. The limitations on Purchaser's
liability under this Paragraph 16 shall be inapplicable to the liability of
Purchaser for payments, if any, due by Purchaser to Seller under Paragraphs 5
and 22 hereof.

     17.  Seller's Default.  In the event of default by Seller under the terms
          ----------------                                                    
of this Agreement occurring prior to Closing, except as otherwise specifically
set forth herein, at Purchaser's option:  (i) Purchaser may terminate this
Agreement by written notice to Seller, whereupon the Earnest Money shall be
immediately returned by Escrow Agent to Purchaser, 

                                       24
<PAGE>
 
and the parties hereto shall have no further rights or obligations hereunder
except for rights and obligations hereunder which expressly survive the
termination of this Agreement, or (ii) Purchaser shall be entitled to an
immediate refund of all but $25.00 of the Earnest Money and to pursue against
Seller any remedy granted to Purchaser at law or in equity, including, without
limitation, specific performance; provided, however, (a) Purchaser shall not
have the right to seek or recover consequential damages arising from Seller's
breach or default under this Agreement, and (b) the damages recoverable against
Seller for any such default occurring prior to Closing shall not exceed
$250,000.00. In the event of any default by Seller occurring after Closing under
any of the terms of this Agreement which survive Closing, Purchaser may pursue
any remedy granted to Purchaser at law or in equity; provided, however,
Purchaser shall not have the right to seek or recover consequential damages
arising from Seller's breach or default under this Agreement.

     18.  Condemnation.  If, prior to the Closing, all or any part of the
          ------------                                                   
Property which Purchaser reasonably determines will interfere with the operation
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
thirty (30) 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 18, 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 such obligations hereunder which expressly survive
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.

     19.  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 Thousand Dollars ($200,000.00) or if the cost of
repair or replacement is not fully covered by Seller's casualty insurance, or if
the damage could result in the termination of the Lease, 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 the Earnest Money shall immediately be returned by
Escrow Agent to Purchaser and the rights, duties, obligations, and liabilities
of all parties hereunder 

                                       25
<PAGE>
 
shall immediately terminate and be of no further force or effect, except for
such obligations hereunder which expressly survive termination of this
Agreement. If Purchaser does not elect to terminate this Agreement pursuant to
this Paragraph 19, or has no right to terminate this Agreement (because the
damage or destruction is fully insured, does not exceed $200,000.00 and could
not result in the termination of the Lease), and the sale of the Property is
consummated, Purchaser shall be entitled to receive all casualty insurance
proceeds paid or payable to Seller by reason of such destruction or damage under
the insurance required to be maintained by the Tenant pursuant to the Lease
(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. 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.

     20.  Hazardous Substances.  Seller agrees and warrants to Purchaser that,
          --------------------                                                
to the best of Seller's knowledge, except as disclosed in the Environmental
Report, (i) no Hazardous Substances, 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 Land has not previously been used as a landfill, cemetery, or as a dump for
garbage or refuse.  Seller hereby indemnifies Purchaser and agrees to holds
Purchaser harmless from and against any lost, cost, damage, liability or expense
due to or arising out of the breach of any representation or warranty contained
in this Paragraph 20; provided, however, Purchaser shall not have the right to
seek or recover consequential damages arising out of the breach of any
representation or warranty contained in this Paragraph 20.  The representations
and warranties set forth in this Paragraph 20 and the indemnification given
herein shall expressly survive the execution and delivery of the Special
Warranty Deed conveying the Real Estate from Seller to Purchaser as provided in
Paragraph 26 hereof.

     21.  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, upon prior
written notice to Seller, this Agreement, and Purchaser's rights and duties
hereunder, may be freely assigned and transferred to any partnership having
Purchaser, Wells Capital, Inc. or Leo 

                                       26

F. Wells, III as a direct or indirect general partner thereof or to The Bank of
New York, as agent for Purchaser or for any partnership having Purchaser, Wells
Capital, Inc. or Leo F. Wells, III as a direct or indirect general partner
thereof, provided that the original Purchaser shall remain liable for all of the
obligations of the Purchaser hereunder arising or accruing prior to such
assignment.

     22.  Broker's Commission.  Seller has agreed to pay to First Fidelity
          -------------------                                             
Mortgage Corporation ("Broker") a real estate sales commission in accordance
with a separate agreement between Seller and Broker.  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 claim asserted by Broker.
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 claim asserted by Broker.  The obligations of Seller and
Purchaser under this Paragraph 22 shall survive the Closing and any termination
of this Agreement.

     23.  Notices.  Wherever any notice or other communication is required or
          -------

     24.  Possession.  Possession of the Property shall be granted by Seller to
          ----------                                                           
Purchaser on the date of Closing, subject only to the Lease and the Permitted
Exceptions.

     25.  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.

     26.  Survival of Provisions.  All covenants, warranties, and agreements set
          ----------------------                                                
forth in this Agreement shall survive the execution or delivery of any and all
deeds and other documents at any time executed or delivered under, pursuant to,
or by reason of this Agreement, and shall survive the payment of all monies made

application thereof to any person or circumstance, shall, for any reason and to

     28.  Purchaser's Authorization.  Purchaser represents to Seller that this

Agreement has been duly authorized and executed on behalf of Purchaser and that
this Agreement constitutes the valid and binding agreement of Purchaser,
enforceful in accordance with these terms, subject to bankruptcy, insolvency,
and similar laws affecting generally the enforcement of creditor's rights.
Neither the execution and delivery of this Agreement nor the consummation of the
transaction contemplated hereby will (i) be in violation of Purchaser's
partnership agreement, (ii) conflict with or result in the breach or violation
of any law, regulation, writ, injunction or decree of any court or governmental
instrumentality applicable to Purchaser, or (iii) constitute a breach of any
evidence of indebtedness or agreement of which Purchaser is a party or by which
Purchaser is bound.

     29.  General Provisions.  No failure of either 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 either 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 the
parties hereto unless such amendment is in writing and executed by both Seller
and Purchaser.  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 assigns. Time is of the essence of this
Agreement.  This Agreement may be executed in multiple counterparts, each of
which shall constitute an original, but all of which taken together shall
constitute one and the same 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 and interpreted under the laws of the Commonwealth of Pennsylvania.
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.

     30.  Reconciliation with Tenant.  As of the date of this Agreement, Seller
          --------------------------                                           
and the Tenant under the Lease have not yet reconciled the amount of "Change
Order Costs" payable by the Tenant to the Seller under the Lease.  Seller
acknowledges that the Purchaser does not desire to acquire the Property if at
the time of Closing any material dispute exists between Seller and the Tenant
regarding the payment of rent, charges or the "Charge Order Costs" under the
Lease.  Purchaser acknowledges that Seller does not desire to sell the Property
if at the time of Closing any material dispute exists between Seller and the
Tenant regarding the payment of rent, charges or "Change Order Costs" under the
Lease, unless Seller reserves certain remedies under the Lease pertaining to the
recovery of such rent, charges and "Change Order Costs".  Accordingly, the
obligations of Purchaser under this Agreement shall be conditioned upon Seller's
agreement to delete from the Assignment and Assumption of Lease to be executed
and delivered at Closing that certain language which is underlined and set forth
in bold print in the form of such Assignment and Assumption of Lease attached
hereto as Exhibit "K".  Likewise, the obligations of Seller under this Agreement
          -----------                                                           
shall be conditioned upon Purchaser's agreement to include in the Assignment and
Assumption of Lease to be executed and delivered at Closing that certain
language which is underlined and set forth in bold print in the form of such
Assignment and Assumption of Lease attached hereto as Exhibit "K".  Seller
                                                      -----------         
agrees to keep Purchaser apprised of the status of Seller's efforts to reconcile
with Tenant the amounts of such rents, charges and "Change Order Costs" payable
by Tenant.  If by the final date of Closing determined in accordance with
Paragraph 11 above, Seller and Purchaser have not yet determined whether the
language which is underlined and set forth in bold print in the form of said
Assignment and Assumption of Lease will be deleted or included, the Closing
shall be postponed until the date which is three (3) business days after Seller
and Purchaser make such determination; provided, however, in no event shall the
final date for Closing be postponed beyond January 29, 1999.  If such

past due shall bear interest at a rate per annum equal to the lesser of (i) the
Maximum Rate (hereinafter defined) or (ii) the Stated Rate (hereinafter defined)
computed on the Annual Basis (hereinafter defined). The term "Stated Rate" as

          (ii) at the election of Maker, but subject to the terms and conditions
      set forth herein, the Fixed Eurodollar Basis (hereinafter defined).

If a Variable Rate applies, then the Stated Rate shall, unless otherwise
specified herein and subject to the following clause, change with each change in
such Variable Rate as of the date of any such change, without notice, subject
always to the limitations set out in this Section 3; provided, however, that if
on any day the Variable Rate shall exceed the maximum permitted by application
of the Maximum Rate in effect on that day, the Variable Rate shall be limited
to, but shall remain at and vary with, the maximum permitted by application of
the Maximum Rate on that day and on each day thereafter until the total amount
of interest accrued at the Variable Rate on the unpaid balance of this Note
equals the total amount of interest which would have accrued if there were no
limitation by the Maximum Rate, or until the earlier payment in full of this
Note.

the actual number of days elapsed and as if each year were composed of 360 days;
however, use of the Annual Basis is subject always to limitation by the Maximum
Rate and in no event shall any such computation result in an amount of interest

interest at the Maximum Rate shall be computed on the Annual Basis of 365 days
(366 in a leap year).

The term "Business Day" as used in this Note means any day on which the offices

Fixed Eurodollar Borrowing, or (b) applicable from day to day, with respect to a
Variable Eurodollar Borrowing, under regulations issued from time to time by the
Board of Governors of the Federal Reserve System (or if more than one such
percentage is so applicable, the daily average for such percentage for those
days during which any such percentage shall be applicable) for determining the
maximum reserve requirement (including, without limitation, any basic, marginal,
supplemental or emergency reserve requirement) for Lender in respect of
liabilities or assets consisting of or including "Eurocurrency Liabilities" as
defined in Regulation D of the Board of Governors of the Federal Reserve Board
as from time to time in effect, whether or not Lender has any Eurocurrency
liabilities subject to such reserve requirement at that time. Eurodollar
Borrowings shall be deemed to constitute Eurocurrency liabilities and as such
shall be deemed subject to reserve requirements without benefits of credits for

          --------------------------

available, the term "Fixed Eurodollar Rate" shall mean, for any Fixed Eurodollar
Borrowing for any Interest Period therefor, the rate per annum appearing on
Reuters Screen LIBO Page as the London interbank offered rate for deposits in
United States dollars at approximately 11:00 a.m. (London time) two Business
Days prior to the first day of such Interest Period for a term comparable to

to the following:

          (i) if any Interest Period would otherwise end on a day which is not a
      Business Day, that Interest Period shall be extended to the next
      succeeding Business Day unless the result of such extension would be to
      extend such Interest Period into another calendar month, in which event
      such Interest Period shall end on the immediately preceding Business Day;
      and

          (ii) any Interest Period which begins on the last Business Day of a
      calendar month (or on a day for which there is no corresponding day in the
      calendar month at the end of such Interest Period) shall, subject to

law or the law of the State of Georgia permits the higher interest rate,
including to the extent permitted by applicable law, any amendments thereof
hereafter or any new law hereafter coming into effect to the extent a higher
Maximum Rate is permitted thereby.  The Maximum Rate shall be applied by taking
into account all amounts characterized by applicable law as interest on the debt
evidenced by this Note, so that the aggregate of all interest does not exceed
the maximum nonusurious amount permitted by applicable law (the "Maximum
                                                                 -------

interest per annum then most recently established by Lender as its "prime rate."
Any such rate is a general reference rate of interest, may not be related to any
other rate, and may not be the lowest or best rate actually charged by Lender to
any customer or a favored rate and may not correspond with future increases or
decreases in interest rates charged by other lenders or market rates in general.

The term "Variable Eurodollar Basis" as used in this Note means a per annum rate

     PLUS two hundred (200) basis points, after adjustment for insurance costs
     and other appropriate regulatory costs and adjustments.

The term "Variable Eurodollar Borrowing" as used in this Note means a separate
          -----------------------------

3750 (or any successor page) as the London interbank offered rate for deposits
in United States dollars at approximately 11:00 a.m. (London time) for a thirty-
day period, with the applicable Variable Eurodollar Rate for each day being the
Variable Eurodollar Rate that appeared, as aforesaid, two Business Days prior to
such day.  If for any reason such rate is not available, the term "Variable
Eurodollar Rate" shall mean, as such rate changes each day, without notice, the
rate per annum appearing on Reuters Screen LIBO Page as the London interbank
offered rate for deposits in United States dollars at approximately 11:00 a.m.
(London time) for a thirty-day period, with the applicable Variable Eurodollar
Rate for each day being the Variable Eurodollar Rate that appeared, as
aforesaid, two Business Days prior to such day; provided, however, if more than
                                                --------  -------              
one rate is specified on Reuters Screen LIBO Page, the applicable rate shall be
the arithmetic mean of all such rates.

  (b) Initial Stated Rate; Application of Prime Rate.  The Stated Rate as of the
      ----------------------------------------------               
 date hereof is the Variable Eurodollar Basis. Maker may elect to change the
 Variable Rate from the Variable Eurodollar Basis to the Prime Rate, or from the
 Prime Rate to the Variable Eurodollar Basis, once per calendar month, which
 election shall be effective on the first (1st) Business Day following receipt
 by Lender of written notice from Maker setting forth the rate elected. Any
 portion of the outstanding principal balance hereof which, prior to the
 Maturity Date, does not bear interest at either the Variable Eurodollar Basis
 or the Fixed Eurodollar Basis, for any reason, shall bear interest at the Prime
 Rate.

  (c)  Election of Fixed Eurodollar Basis. On any Business Day on which (i) a
       ---------------------------------- 
portion of the outstanding principal balance of this Note is then accruing
interest at a Variable Rate (or is scheduled to begin accruing interest at a
Variable Rate on either of the next two (2) Business Days), (ii) such portion of
the outstanding principal balance is equal to or greater than Six Million
Dollars ($6,000,000.00), and (iii) no Default shall have occurred and remain
uncured following the expiration of any applicable grace period, Maker shall
have the right to request that Lender advise Maker as to the current Fixed
Eurodollar Basis, for one or more specified Interest Periods, with respect to
such portion of the outstanding principal balance. The request for such advice
must be received by Lender no later than 9:30 a.m., Atlanta, Georgia time, on
such Business Day. Lender shall endeavor so to advise Maker of the Fixed
Eurodollar Basis no later than 10:00 a.m., Atlanta, Georgia time, on the same
day. Lender's determination of the Fixed Eurodollar Basis shall be conclusive.
No later than 10:00 a.m., Atlanta, Georgia time, on the same day, Maker shall
have the option to elect, subject to the availability to Lender of funds in the
specified amount, at the specified Fixed Eurodollar Rate, for the specified
Interest Period, which election by Maker shall be irrevocable, that such portion
of the outstanding principal balance shall bear interest at the Fixed Eurodollar
Basis, based upon the quoted Fixed Eurodollar Rate, for the specified Interest
Period for such Fixed Eurodollar Rate. Maker shall communicate notice of its
election to exercise the above option by telephone or by telex, but any
telephonic notice shall be immediately confirmed in writing given by Maker to
Lender. Each Fixed Eurodollar Basis selected by Maker shall become effective,
and the Interest Period applicable thereto shall commence, on the second (2nd)
Business Day following the date of such selection. No more than one (1) Fixed
Eurodollar Borrowing may be outstanding at any given time.
<PAGE>
 
  (d) Suspension of Eurodollar Borrowings.  If, at any time,
      -----------------------------------                   

      (i)  Lender shall have reasonably determined (which determination shall be
  conclusive and binding) that by reason of circumstances affecting the London
  interbank market or other Eurodollar market, as applicable, adequate and
  reasonable means do not exist for ascertaining the Fixed Eurodollar Basis or
  the Variable Eurodollar Basis, as the case may be, or

      (ii) Lender shall have reasonably determined (which determination shall be
  conclusive and binding) that the Fixed Eurodollar Basis or the Variable
  Eurodollar Basis, as the case may be, will not adequately and fairly reflect
  the cost to Lender of such Eurodollar Borrowing,

then Lender shall forthwith give notice thereof to Maker, whereupon until Lender
notifies Maker that the circumstances giving rise to such suspension no longer
exist, the obligation of Lender to allow new Fixed Eurodollar Borrowings or
Variable Eurodollar Borrowings, as the case may be, shall be suspended.

  (e) Conversion to Prime Rate.  If, after the date of this Note, the adoption
      ------------------------                                        
of any applicable law, rule or regulation, or any change therein, or any change
in the interpretation or administration thereof by any governmental authority,
central bank or comparable agency charged with the interpretation or
administration thereof, or compliance by Lender (or any of its non-United States
offices) with any request or directive (whether or not having the force of law)
of any such authority, central bank or comparable agency shall make it unlawful
or impossible for Lender to make, maintain or fund Eurodollar Borrowings, Lender
shall forthwith give notice thereof to Maker, whereupon until Lender notifies
Maker that the circumstances giving rise to such suspension no longer exist, the
obligation of Lender to allow Eurodollar Borrowings shall be suspended. If
Lender shall determine that it may not lawfully continue to maintain any
outstanding Eurodollar Borrowing to maturity and shall so specify in such
notice, such Eurodollar Borrowing shall be immediately converted to a borrowing
at the Prime Rate.

  (f) Additional Compensation to Lender.  If, after the date of this Note, the
      ---------------------------------                                       
adoption of any applicable law, rule or regulation, or any change therein, or
any change in the interpretation or administration thereof by any governmental
authority, central bank or comparable agency charged with the interpretation or
administration thereof, or compliance by Lender with any request or directive
(whether or not having the force of law) of any such authority, central bank or
comparable agency:

      (i) shall subject Lender to any tax, duty or other direct charge with
  respect to Eurodollar Borrowings or this Note or shall change the basis of
  taxation of payments to Lender of the principal of or interest on Eurodollar
  Borrowings or any other amounts due under this Note in respect of Eurodollar
  Borrowings or its obligations to allow Eurodollar Borrowings (except for
  changes in the rate of tax on the overall net income of Lender imposed by the
  jurisdiction in which Lender's principal executive office is located); or
<PAGE>
 
      (ii) shall impose, modify or deem applicable any reserve, special deposit
  or similar requirement (including, without limitation, any such requirement
  imposed by the Board of Governors of the Federal Reserve System, but excluding
  with respect to any Eurodollar Borrowing any such requirement included in an
  applicable Eurodollar Reserve Percentage) against assets of, deposits with or
  for the account of, or credit extended by, Lender or shall impose on Lender or
  the interbank market for Eurodollar deposits any other condition affecting
  Eurodollar Borrowings, this Note or the obligation of Lender to allow
  Eurodollar Borrowings;

and the result of any of the foregoing is to increase the cost to Lender of
allowing or maintaining Eurodollar Borrowings or to reduce the amount of any sum
received or receivable by Lender under this Note with respect thereto, by an
amount deemed by Lender, in its good faith judgment, to be material, then,
within fifteen (15) days after demand by Lender, Maker shall pay to Lender such
additional amount or amounts as will compensate Lender for such increased cost
or reduction. Lender will promptly notify Maker of any event of which it has
knowledge, occurring after the date hereof, which will entitle Lender to
compensation pursuant to this paragraph. A certificate of Lender claiming
compensation under this paragraph, setting forth the additional amount or
amounts to be paid to it hereunder and explaining in reasonable detail the
estimates, data and calculations of such amount, shall be conclusive and binding
in the absence of manifest error. In determining such amount, Lender may use any
reasonable averaging and attribution methods. In lieu of paying the compensation
to Lender described in this paragraph, Maker may elect, promptly upon receiving
notice from Lender of the event entitling Lender to such compensation, to have
any Eurodollar Borrowing converted to a borrowing at the Prime Rate, subject to
Maker's paying to Lender a Make-Whole Amount (hereinafter defined) as a result
of such conversion.

      (g) Past Due Rate.  From and after maturity (whether by acceleration or
          -------------          
otherwise), any principal of, and to the extent permitted by applicable law,
any interest on this Note, and any other sum payable hereunder, shall bear
interest, payable on demand, at a rate per annum (the "Past Due Rate") equal to
                                                       -------------  
the lesser of (i) the Stated Rate plus four percent (4%) or (ii) the Maximum
Rate.

      (h) Late Charge.  If any principal or interest is not paid when due, Maker
          -----------                                                           
shall pay, on demand, a late charge of four cents ($.04) for each dollar of each
installment which becomes past due for a period exceeding ten (10) days to help
defray the added expense incurred in handling said delinquent installment,
provided that in no event shall interest be due or payable in excess of the
Maximum Rate.

  4.  Prepayment.  Maker may prepay the principal balance of this Note, in full
      ----------                                                               
at any time or in part from time to time, provided that (i) Lender shall have
actually received from Maker at least five (5) business days' prior written
notice of Maker's intent to prepay, of the amount of principal which will be
prepaid (the "Prepaid Principal") and of the date on which the prepayment will
              -----------------                                               
be made; (ii) the prepayment must not, in Lender's judgment, result in a breach
or loss of rights under any commitment or agreement by any third party for
payment or purchase of the loan evidenced by this Note or of the Property; (iii)
each prepayment shall be in the amount of $1,000.00 
<PAGE>
 
or a larger integral multiple of $1,000.00 (unless the prepayment retires the
outstanding balance of this Note in full); and (iv) each prepayment shall be in
the amount of 100% of the Prepaid Principal, plus accrued unpaid interest
thereon to the date of prepayment, plus any other sums which have become due to
Lender under the Loan Documents on or before the date of prepayment but have not
been paid, and, if the Prepaid Principal bears interest at a Fixed Eurodollar
Basis, plus the Make-Whole Amount (hereinafter defined). The "Make-Whole Amount"
                                                              -----------------
shall equal the aggregate of any loss, cost, liability or expense incurred by
Lender as a result of a prepayment or conversion of any Fixed Eurodollar
Borrowing or portion thereof, including, without limitation, any loss in
obtaining, liquidating or employing funds from third parties, and any loss of
yield, as determined by Lender, on a present value basis, in its judgment
reasonably exercised; but the Make-Whole Amount shall in no event be less than
zero and nothing herein shall be construed or operate to require Maker to pay a
Make-Whole Amount except in connection with Maker's exercise of the right to
prepay Fixed Eurodollar Borrowings granted above or the conversion of a Fixed
Eurodollar Borrowing to a borrowing at the Prime Rate, as described in Section
3, above, or to pay any amount greater than is permitted by applicable law. If a
Make-Whole Amount will be due, Lender shall notify Maker of the amount and basis
of determination of the Make-Whole Amount. If this Note is prepaid in full, any
commitment of Lender for further advances shall automatically terminate.

  5.  Certain Provisions Regarding Payments.  All payments made as scheduled on
      -------------------------------------                                    
this Note shall be applied, to the extent thereof, to accrued but unpaid
interest, unpaid principal, and any other sums due and unpaid to Lender under
the Loan Documents, in such manner and order as Lender may elect in its
discretion. All prepayments on this Note shall be applied, to the extent
thereof, to accrued but unpaid interest on the amount prepaid, to the remaining
principal installments, and any other sums due and unpaid to Lender under the
Loan Documents, in such manner and order as Lender may elect in its discretion,
including but not limited to application to principal installments in inverse
order of maturity. Except to the extent that specific provisions are set forth
in this Note or another Loan Document with respect to application of payments,
all payments received by the holder hereof shall be applied, to the extent
thereof, to the indebtedness secured by the Mortgage in such manner and order as
Lender may elect in its discretion, any instructions from Maker or anyone else
to the contrary notwithstanding. Remittances in payment of any part of the
indebtedness other than in the required amount in immediately available U.S.
funds shall not, regardless of any receipt or credit issued therefor, constitute
payment until the required amount is actually received by the holder hereof in
immediately available U.S. funds and shall be made and accepted subject to the
condition that any check or draft may be handled for collection in accordance
with the practice of the collecting bank or banks. Acceptance by the holder
hereof of any payment in an amount less than the amount then due on any
indebtedness shall be deemed an acceptance on account only and shall not in any
way excuse the existence of a Default (hereinafter defined). Payments received
after 2:00 o'clock p.m. Atlanta, Georgia time shall be deemed to be received on,
and shall be posted as of, the following business day. Whenever any payment
under this Note or any other Loan Document falls on a day on which the offices
of Lender are not open for the conduct of business in Atlanta, Georgia, such
payment may be made on the next succeeding day on which the offices of Lender
are open for such business, and the extension of time in such case shall be
included in the computation of interest.
<PAGE>
 
   6. Defaults. It shall be a default ("Default") under this Note and each of
      --------                          -------                      
the other Loan Documents if (a) any principal, interest or other amount of money
due under this Note is not paid in full when due, regardless of how such amount
may have become due; or (b) there shall occur any default or event of default
under the Mortgage or any other Loan Document. Upon the occurrence of a Default,
subject to the terms of Section 4.2 of the Mortgage, the holder hereof shall
have the rights to declare the unpaid principal balance and accrued but unpaid
interest on this Note at once due and payable (and upon such declaration, the
same shall be at once due and payable), to foreclose any liens and security
interests securing payment hereof and to exercise any of its other rights,
powers and remedies under this Note, under any other Loan Document, or at law or
in equity.

  7.  Rights Cumulative.  All of the rights, remedies, powers and privileges
      -----------------                                          
(together, "Rights") of the holder hereof provided for in this Note and in any
            ------                                                 
other Loan Document are cumulative of each other and of any and all other Rights
at law or in equity. The resort to any Right shall not prevent the concurrent or
subsequent employment of any other appropriate Right. No single or partial
exercise of any Right shall exhaust it, or preclude any other or further
exercise thereof, and every Right may be exercised at any time and from time to
time. No failure by the holder hereof to exercise, nor delay in exercising any
Right, including but not limited to the right to accelerate the maturity of this
Note, shall be construed as a waiver of any Default or as a waiver of any Right.
Without limiting the generality of the foregoing provisions, the acceptance by
the holder hereof from time to time of any payment under this Note which is past
due or which is less than the payment in full of all amounts due and payable at
the time of such payment, shall not (i) constitute a waiver of or impair or
extinguish the right of the holder hereof to accelerate the maturity of this
Note or to exercise any other Right at the time or at any subsequent time, or
nullify any prior exercise of any such Right, or (ii) constitute a waiver of the
requirement of punctual payment and performance or a novation in any respect.

  8.  Costs of Collection.  If any holder of this Note retains an attorney in
      -------------------                                                 
connection with any Default or at maturity or to collect, enforce or defend this
Note or any other Loan Document in any lawsuit or in any probate,
reorganization, bankruptcy or other proceeding, or if Maker sues any holder in
connection with this Note or any other Loan Document and does not prevail, then
Maker agrees to pay to each such holder, in addition to principal, interest and
any other sums owing to Lender under the Loan Documents, all reasonable costs
and expenses incurred by such holder in trying to collect this Note or in any
such suit or proceeding, including reasonable attorneys' fees.

  9.  Controlling Agreement.  All parties to the Loan Documents intend to comply
      ---------------------                                              
with applicable usury law. All existing and future agreements regarding the debt
evidenced by this Note are hereby limited and controlled by the provisions of
this Section. In no event (including but not limited to prepayment, default,
demand for payment, or acceleration of maturity) shall the interest taken,
reserved, contracted for, charged or received under this Note or under any of
the other Loan Documents or otherwise, exceed the Maximum Amount. If, from any
possible construction of any document, interest would otherwise be payable in
excess of the Maximum Amount, then, ipso facto, such document shall be reformed
                                    ---- -----                     
and the interest payable reduced to the Maximum Amount, without necessity of
execution of any amendment or new document. If the 
<PAGE>
 
holder hereof ever receives interest in an amount which apart from this
provision would exceed the Maximum Amount, the excess shall, without penalty, be
applied to the unpaid principal of this Note in inverse order of maturity of
installments and not to the payment of interest, or be refunded to the payor, at
the election of the holder hereof in its sole discretion or as required by
applicable law. The holder hereof does not intend to charge or receive unearned
interest on acceleration. All interest paid or agreed to be paid to the holder
hereof shall be spread throughout the full term (including any renewal or
extension) of the debt so that the amount of interest does not exceed the
Maximum Amount.

  10. General Provisions.  Time is of the essence with respect to Maker's
      ------------------                                                 
obligations under this Note. Maker and all sureties, endorsers, guarantors and
any other party now or hereafter liable for the payment of this Note in whole or
in part, hereby severally (i) waive demand, presentment for payment, notice of
dishonor and of nonpayment, protest, notice of protest, notice of intent to
accelerate, notice of acceleration and all other notices (except any notices
which are specifically required by this Note or any other Loan Document), filing
of suit and diligence in collecting this Note or enforcing any of the security
herefor; (ii) agree to any substitution, subordination, exchange or release of
any such security or the release of any party primarily or secondarily liable
hereon; (iii) agree that the holder hereof shall not be required first to
institute suit or exhaust its remedies hereon against Maker or others liable or
to become liable hereon or to perfect or enforce its rights against them or any
security herefor; (iv) consent to any extensions or postponements of time of
payment of this Note for any period or periods of time and to any partial
payments, before or after maturity, and to any other indulgences with respect
hereto, without notice thereof to any of them; and (v) submit (and waive all
rights to object) to non-exclusive personal jurisdiction in the State of
Georgia, and venue in the county in which payment is to be made as specified in
Section 1 of this Note, for the enforcement of any and all obligations under the
Loan Documents.

Maker and all other parties to this Note severally waive any and all homestead
and exemption rights which any of them or the family of any of them may have
under or by virtue of the Constitution or laws of the United States of America
or of any state as against this Note, any renewal hereof, or any indebtedness
evidenced hereby.  Maker and all other parties to this Note jointly and
severally transfer, convey and assign to Lender or any other holder a sufficient
amount of property or money set apart as exempt to pay the indebtedness
evidenced hereby, or any renewal hereof and do hereby, jointly and severally,
appoint Lender and any other holder the attorney-in-fact for each of them to
claim any and all homestead exemptions allowed by law.

A determination that any provision of this Note is unenforceable or invalid
shall not affect the enforceability or validity of any other provision and the
determination that the application of any provision of this Note to any person
or circumstance is illegal or unenforceable shall not affect the enforceability
or validity of such provision as it may apply to other persons or circumstances.
This Note may not be amended except in a writing specifically intended for the
purpose and executed by the party against whom enforcement of the amendment is
sought. The holder of this Note may, from time to time, sell or offer to sell
the loan evidenced by this Note, or interests therein, to one or more assignees
or participants and is hereby authorized to disseminate any information it now
has or hereafter obtains pertaining to the loan evidenced by this Note,
including, without limitation, any 
<PAGE>
 
security for this Note and credit or other information on Maker, any of its
principals and any guarantor of this Note, to any assignee or participant or
prospective assignee or prospective participant, holder's affiliates, including
NationsBanc Montgomery Securities LLC, any regulatory body having jurisdiction
over the holder of this Note and to any other parties as necessary or
appropriate in the holder of this Note's reasonable judgment. Maker shall
execute, acknowledge and deliver any and all instruments reasonably requested by
the holder of this Note in connection therewith and to the extent, if any,
specified in any such assignment or participation, such companies, assignees or
participants shall have the rights and benefits with respect to this Note and
the other Loan Documents as such persons would have if such persons were Lender
hereunder. Maker warrants and represents to Lender and all other holders of this
Note that the loan evidenced by this Note is and will be for business or
commercial purposes and not primarily for personal, family, or household use.
The terms, provisions, covenants and conditions hereof shall be binding upon
Maker and the representatives, successors and assigns of Maker. Captions and
headings in this Note are for convenience only and shall be disregarded in
construing it. THIS NOTE, AND ITS VALIDITY, ENFORCEMENT AND INTERPRETATION,

SHALL BE GOVERNED BY GEORGIA LAW (WITHOUT REGARD TO ANY CONFLICT OF LAWS
- ------------------------------------------------------------------------
PRINCIPLES) AND APPLICABLE UNITED STATES FEDERAL LAW.

     THIS OPEN-END MORTGAGE, ASSIGNMENT OF LEASES AND RENTS, SECURITY
AGREEMENT AND FINANCING STATEMENT (this "Mortgage") dated February 4, 1999, is
                                         --------                               
executed and delivered by WELLS OPERATING PARTNERSHIP, L.P., a Delaware limited

              ---------

                   ---------------------------------------                
is made to secure and enforce the payment and performance of the following
promissory notes, obligations, indebtedness and liabilities and all renewals,
extensions, supplements, increases, and modifications thereof in whole or in
part from time to time:  (a) the Promissory Note and all other notes given in

as from time to time renewed, extended, supplemented, increased or modified and
all other notes given in substitution therefor, or in modification, renewal or

                                                                      ----

debts, obligations and liabilities of Mortgagor of every kind and character now
or hereafter existing in favor of Mortgagee, however and whenever incurred,
whether direct or indirect, primary or secondary, joint or several, fixed or
contingent, secured or unsecured, and whether originally payable to Mortgagee or
to a third party and subsequently acquired by Mortgagee; provided, however, and
notwithstanding the foregoing provisions of this clause (c), this Mortgage shall
not secure any such other loan, advance, debt, obligation or liability with
respect to which Mortgagee is by applicable law prohibited from obtaining a lien
or security title on real estate nor shall this clause (c) operate or be
effective to constitute or require any assumption or payment by any person, in
any way, of any debt of any other person to the extent that the same would

indebtedness referred to in this Section 1.4 is hereinafter sometimes referred
to as the "secured indebtedness" or the "indebtedness secured hereby."
           --------------------          ---------------------------  

             ARTICLE 2 - REPRESENTATIONS, WARRANTIES AND COVENANTS
                         -----------------------------------------

     Section 2.1.  Mortgagor represents, warrants, and covenants as follows:

     (a)  Payment and Performance.  Mortgagor will make due and punctual
          -----------------------                                       
payment of the secured indebtedness.  Mortgagor will timely and properly perform
and comply with all of the covenants, agreements, and conditions imposed upon it
by this Mortgage and the other Loan Documents and will not permit a default to
occur hereunder or thereunder.  Time shall be of the essence in this Mortgage.

     (b)  Title and Permitted Encumbrances.  Mortgagor has, in Mortgagor's
          --------------------------------                                
own right, and Mortgagor covenants to maintain, lawful, good and marketable fee
simple title to the Property, is lawfully seized and possessed of the Property
and every part thereof, and has the right to convey the same, free and clear of
all liens, charges, debts, claims, interests, and encumbrances except for (i)
the matters, if any, set forth under the heading "Permitted Exceptions" in
Exhibit B hereto, which are Permitted Exceptions only to the extent the same are
valid and subsisting and affect the Property, (ii) the liens and security
interests evidenced by this Mortgage, (iii) other liens and security interests
(if any) in favor of Mortgagee (the matters described in the foregoing clauses
(i), 
<PAGE>
 
(ii) and (iii) being herein called the "Permitted Encumbrances"). Mortgagor, and
                                        ----------------------    
Mortgagor's successors and assigns, will warrant and forever defend title to the
Property, subject as aforesaid, to Mortgagee and its successors and assigns,
against the claims and demands of all persons claiming or to claim the same or
any part thereof. Mortgagor will punctually pay, perform, observe and keep all
covenants, obligations and conditions in or pursuant to any Permitted
Encumbrance and will not modify or permit modification of any Permitted
Encumbrance without the prior written consent of Mortgagee. Inclusion of any
matter as a Permitted Encumbrance does not constitute approval or waiver by
Mortgagee of any existing or future violation or other breach thereof by
Mortgagor, by the Property or otherwise. If any right or interest of Mortgagee
in the Property or any part thereof shall be endangered or questioned or shall
be attacked directly or indirectly, Mortgagee (whether or not named as the party
to legal proceedings with respect thereto) is hereby authorized and empowered to
take such steps as in its discretion may be proper for the defense of any such
legal proceedings or the protection of such right or interest of Mortgagee,
including but not limited to the employment of independent counsel, the
prosecution or defense of litigation, and the compromise or discharge of adverse
claims. All expenditures so made of every kind and character shall be a demand
obligation (which obligation Mortgagor hereby promises to pay) owing by
Mortgagor to Mortgagee, and Mortgagee shall be subrogated to all rights of the
person receiving such payment.

     (c)  Taxes and Other Impositions.  Mortgagor will pay, or cause to be
          ---------------------------                                     
paid, all taxes, assessments and other charges or levies imposed upon or against
or with respect to the Property or the ownership, use, occupancy or enjoyment of
any portion thereof, or any utility service thereto, as the same become due and
payable, including but not limited to all ad valorem taxes assessed against the
Property or any part thereof, and shall deliver promptly to Mortgagee such
evidence of the payment thereof as Mortgagee may require.

     (d)  Insurance.
          --------- 

          I.     Requirements Regarding Insurance.
                 -------------------------------- 

          Mortgagor shall obtain and maintain at Mortgagor's sole expense: (1)
mortgagee title insurance issued to Mortgagee covering the Premises as required
by Mortgagee; (2) all-risk insurance with respect to all insurable Property,
against loss or damage by fire, lightning, windstorm, explosion, hail, tornado
and such hazards as are presently included in so-called "all-risk" coverage and
against such other insurable hazards as Mortgagee may require, in an amount not
less than 100% of the full replacement cost, including the cost of debris
removal, without deduction for depreciation and sufficient to prevent Mortgagor
and Mortgagee from becoming a coinsurer, such insurance to be in builder's risk
(non-reporting) form during and with respect to any construction on the
Premises; (3) if and to the extent any portion of the Improvements is in a
special flood hazard area, a flood insurance policy in an amount equal to the
lesser of the principal face amount of the Note or the maximum amount available;
(4) comprehensive general public liability insurance, on an "occurrence" basis,
for the benefit of Mortgagor and Mortgagee as named insureds; (5) statutory
workers' compensation insurance with respect to any work on or about the
Premises; and (6) such other insurance on the Property as may from time to time
be required by Mortgagee (including but not limited to rental loss or business
interruption insurance, boiler and machinery insurance, earthquake insurance,
and war risk 
<PAGE>
 
insurance) and against other insurable hazards or casualties which at the time
are commonly insured against in the case of premises similarly situated, due
regard being given to the height, type, construction, location, use and
occupancy of buildings and improvements. All insurance policies shall be issued
and maintained by insurers, in amounts, with deductibles, and in form
satisfactory to Mortgagee, and shall require not less than thirty (30) days'
prior written notice to Mortgagee of any cancellation or change of coverage. All
insurance policies maintained, or caused to be maintained, by Mortgagor with
respect to the Property, except for public liability insurance, shall provide
that each such policy shall be primary without right of contribution from any
other insurance that may be carried by Mortgagor or Mortgagee and that all of
the provisions thereof, except the limits of liability, shall operate in the
same manner as if there were a separate policy covering each insured. If any
insurer which has issued a policy of title, hazard, liability or other insurance
required pursuant to this Mortgage or any other Loan Document becomes insolvent
or the subject of any bankruptcy, receivership or similar proceeding or if in
Mortgagee's reasonable opinion the financial responsibility of such insurer is
or becomes inadequate, Mortgagor shall, in each instance promptly upon the
request of Mortgagee and at Mortgagor's expense, obtain and deliver to Mortgagee
a like policy (or, if and to the extent permitted by Mortgagee, a certificate of
insurance) issued by another insurer, which insurer and policy meet the
requirements of this Mortgage or such other Loan Document, as the case may be.
Without limiting the discretion of Mortgagee with respect to required
endorsements to insurance policies, all such policies for loss of or damage to
the Property shall contain a standard mortgagee clause (without contribution)
naming Mortgagee as mortgagee with loss proceeds payable to Mortgagee
notwithstanding (i) any act, failure to act or negligence of or violation of any
warranty, declaration or condition contained in any such policy by any named
insured; (ii) the occupation or use of the Property for purposes more hazardous
than permitted by the terms of any such policy; (iii) any foreclosure or other
action by Mortgagee under the Loan Documents; or (iv) any change in title to or
ownership of the Property or any portion thereof, such proceeds to be held for
application as provided in the Loan Documents. The originals of each initial
insurance policy (or to the extent permitted by Mortgagee, a copy of the
original policy and a satisfactory certificate of insurance) shall be delivered
to Mortgagee at the time of execution of this Mortgage, with premiums fully
paid, and each renewal or substitute policy (or certificate) shall be delivered
to Mortgagee, with premiums fully paid, at least ten (10) days before the
termination of the policy it renews or replaces. Mortgagor shall pay all
premiums on policies required hereunder as they become due and payable and
promptly deliver to Mortgagee evidence satisfactory to Mortgagee of the timely
payment thereof. If any loss occurs at any time when Mortgagor has failed to
perform Mortgagor's covenants and agreements in this paragraph, Mortgagee shall
nevertheless be entitled to the benefit of all insurance covering the loss and
held by or for Mortgagor, to the same extent as if it had been made payable to
Mortgagee. Upon any foreclosure hereof or transfer of title to the Property in
extinguishment of the whole or any part of the secured indebtedness, all of
Mortgagor's right, title and interest in and to the insurance policies referred
to in this Section (including unearned premiums) and all proceeds payable
thereunder shall thereupon vest in the purchaser at foreclosure or other such
transferee, to the extent permissible under such policies. Mortgagee shall have
the right (but not the obligation) to make proof of loss for, settle and adjust
any claim under, and receive the proceeds of, all insurance for loss of or
damage to the Property, and the expenses incurred by Mortgagee in the adjustment
and collection of insurance proceeds shall be a part of the secured indebtedness
and shall be due and payable to Mortgagee on demand. Mortgagee shall not be,
under any circumstances, liable or responsible for failure to collect or
<PAGE>
 
exercise diligence in the collection of any of such proceeds or for the
obtaining, maintaining or adequacy of any insurance or for failure to see to the
proper application of any amount paid over to Mortgagor. Subject to the terms of
Subsection II, below, any such proceeds received by Mortgagee shall, after
deduction therefrom of all reasonable expenses actually incurred by Mortgagee,
including attorneys' fees, at Mortgagee's option be (1) released to Mortgagor,
or (2) applied (upon compliance with such terms and conditions as may be
required by Mortgagee) to repair or restoration, either partly or entirely, of
the Property so damaged, or (3) applied to the payment of the secured
indebtedness in such order and manner as Mortgagee, in its sole but reasonable
discretion, may elect, whether or not due. In any event, the unpaid portion of
the secured indebtedness shall remain in full force and effect and the payment
thereof shall not be excused. Mortgagor shall at all times comply with the
requirements of the insurance policies required hereunder and of the issuers of
such policies and of any board of fire underwriters or similar body as
applicable to or affecting the Property.

          II.  Restoration Advances.
               ---------------------

          (i)  Mortgagee agrees that in the event that all or a portion of the
Improvements shall be destroyed or damaged by fire, explosion, windstorm, hail
or any other casualty against which insurance is required under this Mortgage,
Mortgagee will elect to apply the insurance proceeds which remain after payment
of the expenses of collection thereof as provided in Subsection I, above (called
the "Proceeds" below in this Subsection), or so much thereof as is required, to
restoration of the portion of the Premises damaged, as nearly as practicable to
its value, character and condition immediately prior to such casualty (the
"Restoration"), provided that all of the following conditions precedent are
satisfied in full not later than ninety (90) days after the date on which the
casualty loss occurs:

          A)   no default shall have occurred and shall remain uncured following
     the expiration of any grace or cure period;

          B)   all tenants having present or future possessory rights under
     Leases (hereinafter defined), including without limitation the tenant under
     that certain Build-To-Suit Office Lease Agreement (the "Pennsylvania
                                                             ------------
     Cellular Lease") dated as of September 26, 1997, by and among Walsh Higgins
     --------------                                                             
     No. 33, L.P., a Pennsylvania limited partnership, as Landlord, Pennsylvania
     Cellular Telephone Corp., a North Carolina corporation, as Tenant, and
     Walsh, Higgins & Company, an Illinois corporation, as Contractor, as
     amended, the Landlord's interest thereunder having been assigned to
     Mortgagor, have agreed in a manner satisfactory to Mortgagee that their
     Leases will continue in full force and effect and, if necessary, the time
     for taking or regaining possession of the demised premises under such
     Leases will be extended by the time necessary to complete the Restoration;

          C)   all parties having operating, management or franchise interests
     in, and arrangements concerning, the Property have agreed that they will
     continue their interests and arrangements for the contract terms then in
     effect following the Restoration;
<PAGE>
 
          D)   all parties having commitments to provide financing with respect
     to the Property, to purchase Mortgagor's interest in full or in part in the
     Property or to purchase or pay the loan evidenced by the Note
     (collectively, "Commitment Providers") have agreed in a manner satisfactory
     to Mortgagee that their commitments will continue in full force and effect
     and, if necessary, the expiration of such commitments will be extended by
     the time necessary to complete the Restoration;

          E)   Mortgagor has presented evidence satisfactory to Mortgagee, and
     Mortgagee has reasonably determined, that the Restoration can be
     accomplished within a reasonable period of time and in any event prior to
     the Maturity Date (as defined in the Note);

          F)   Mortgagor has delivered or caused to be delivered to Mortgagee,
     and Mortgagee has approved, complete final plans and specifications (the
     "Restoration Plans") for the work to be performed in connection with the
     Restoration (hereinafter called the "Restoration Work") prepared and sealed
     by an architect (the "Architect") acceptable to Mortgagee, with evidence
     satisfactory to Mortgagee of the approval of the Restoration Plans by all
     Commitment Providers and by all governmental authorities and all tenants
     under Leases whose approval is required;

          G)   Mortgagor has delivered or caused to be delivered to Mortgagee a
     signed estimate approved in writing by the Architect, stating the entire
     cost of completing the Restoration Work;

          H)   Mortgagor has entered into, and has furnished to Mortgagee a copy
     of, a fixed price construction contract satisfactory to Mortgagee, with a
     contractor reasonably acceptable to Mortgagee, bonded to the extent
     required by Mortgagee, for the Restoration Work and such contractor shall
     have executed a waiver of its right and the right of all subcontractors and
     materialmen to file mechanics' liens with respect to the Restoration Work;

          I)   if Mortgagee has determined that (i) the projected cost of the
     Restoration Work substantially in accordance with the Restoration Plans
     exceeds (ii) the available Proceeds held by Mortgagee, then Mortgagor has
     deposited with Mortgagee funds sufficient to cover the excess cost;

          J)   Mortgagor has furnished all insurance coverage required by
     Mortgagee pursuant to Subsection 2.1(d)(I), above; and

          K)   Mortgagee has determined that it will not incur any liability to
     any person as a result of such use of the Proceeds.

          If all of the foregoing conditions have not been satisfied within the
     time limit specified above, then Mortgagee may, at its option, apply such
     Proceeds to the indebtedness 
<PAGE>
 
     secured hereby, whether or not due, in such order and manner as Mortgagee
     elects.

          (ii)  To the extent that Mortgagee elects to apply the Proceeds to the
     restoration or reconstruction of the Improvements, then disbursement of the
     Proceeds for Restoration or Restoration Work shall be subject to and shall
     be made in accordance with the customary practices of Mortgagee governing
     the disbursement of construction loans.  If Mortgagee determines from time
     to time that (i) the estimated cost of the Restoration substantially in
     accordance with the Restoration Plans exceeds (ii) the available Proceeds
     held by Mortgagee plus all other available funds deposited by Mortgagor
     with Mortgagee for the purpose of the Restoration, then Mortgagor shall
     deposit additional funds with Mortgagee to cover the excess cost before
     Mortgagee shall be required to disburse any such Proceeds or other
     available funds for Restoration costs.  Any such funds provided by
     Mortgagor to cover excess costs shall be used for the costs of Restoration
     prior to disbursement of any of the Proceeds for such costs.

          (iii) Any such Proceeds and additional funds provided by Mortgagor
     which are held by Mortgagee under this Subsection II shall be held by
     Mortgagee in an account of Mortgagee's selection until disbursed for
     Restoration or otherwise applied as herein provided.  Mortgagee's receipt
     and custody of such Proceeds or additional funds shall not constitute a
     repayment of any of the indebtedness secured hereby, unless and until such
     Proceeds or additional funds are actually applied against the indebtedness
     secured hereby in accordance with this Mortgage.  No disbursement of such
     Proceeds for Restoration costs shall constitute an advance of the loan
     evidenced by the Note or increase the principal amount of such loan.  If
     surplus Proceeds remain after completion of the Restoration and payment of
     all costs therefor, then such surplus Proceeds shall be applied against the
     indebtedness secured hereby in such manner and order as Mortgagee elects.
     If surplus funds then remain from additional funds provided by Mortgagor to
     cover excess costs of Restoration, then such surplus funds shall be
     returned to Mortgagor, provided that no uncured default shall exist
     hereunder.

          (iv)  In any event, upon the occurrence of a default at any time, and
     the expiration of any applicable grace or cure period without the curing
     thereof, Mortgagee may (but has no obligation to) apply all or any portion
     of such Proceeds or additional funds provided by Mortgagor in Mortgagee's
     possession to the payment of the indebtedness secured hereby, whether or
     not due, in such order and manner as Mortgagee elects, and/or to the cure
     of any default without waiving the same.

     (e)  Reserve for Insurance, Taxes and Assessments.  Upon request of
          --------------------------------------------                  
Mortgagee, to secure certain of Mortgagor's obligations in paragraphs (c) and
(d) above, but not in lieu of such obligations, Mortgagor will deposit with
Mortgagee a sum equal to ad valorem taxes, assessments and charges (which
charges for the purpose of this paragraph shall include without limitation any
recurring charge which could result in a lien against the Property) against the
Property for the current year and the premiums for such policies of insurance
for the current year, all as estimated by Mortgagee and prorated to the end of
the calendar month following the month during which Mortgagee's request is made,
and thereafter will deposit with Mortgagee, on each date when an 
<PAGE>
 
installment of principal and/or interest is due on the Note, sufficient funds
(as estimated from time to time by Mortgagee) to permit Mortgagee to pay at
least fifteen (15) days prior to the delinquency date thereof, the next maturing
ad valorem taxes, assessments and charges and premiums for such policies of
insurance. Mortgagee shall have the right to rely upon tax information furnished
by applicable taxing authorities in the payment of such taxes or assessments and
shall have no obligation to make any protest of any such taxes or assessments.
Any excess over the amounts required for such purposes shall be held by
Mortgagee for future use, applied to any secured indebtedness or refunded to
Mortgagor, at Mortgagee's option, and any deficiency in such funds so deposited
shall be made up by Mortgagor upon demand of Mortgagee. All such funds so
deposited shall bear interest at the rate applicable to the account selected by
Mortgagee for such funds, may be mingled with the general funds of Mortgagee and
shall be applied by Mortgagee toward the payment of such taxes, assessments,
charges and premiums when statements therefor are presented to Mortgagee by
Mortgagor (which statements shall be presented by Mortgagor to Mortgagee a
reasonable time before the applicable amount is delinquent); provided, however,
that, if a default shall have occurred hereunder, such funds may at Mortgagee's
option be applied to the payment of the secured indebtedness in the order
determined by Mortgagee in its sole discretion, and that Mortgagee may (but
shall have no obligation) at any time, in its discretion, apply all or any part
of such funds toward the payment of any such taxes, assessments, charges or
premiums which are past due, together with any penalties or late charges with
respect thereto. The conveyance or transfer of Mortgagor's interest in the
Property for any reason (including without limitation the foreclosure of a
subordinate lien or security interest or a transfer by operation of law) shall
constitute an assignment or transfer of Mortgagor's interest in and rights to
such funds held by Mortgagee under this paragraph but subject to the rights of
Mortgagee hereunder.

     (f) Condemnation.  Mortgagor shall notify Mortgagee immediately of any
         ------------                                                      
threatened or pending proceeding for condemnation affecting the Property or
arising out of damage to the Property, and Mortgagor shall, at Mortgagor's
expense, diligently prosecute any such proceedings.  Mortgagee shall have the
right (but not the obligation) to participate in any such proceeding and to be
represented by counsel of its own choice.  Mortgagee shall be entitled to
receive all sums which may be awarded or become payable to Mortgagor for the
condemnation of the Property, or any part thereof, for public or quasi-public
use, or by virtue of private sale in lieu thereof, and any sums which may be
awarded or become payable to Mortgagor for injury or damage to the Property.
Mortgagor shall, promptly upon request of Mortgagee, execute such additional
assignments and other documents as may be necessary from time to time to permit
such participation and to enable Mortgagee to collect and receipt for any such
sums. All such sums are hereby assigned to Mortgagee, and shall, after deduction
therefrom of all reasonable expenses actually incurred by Mortgagee, including
attorneys' fees, at Mortgagee's option be (1) released to Mortgagor, or (2)
applied (upon compliance with such terms and conditions as may be required by
Mortgagee) to repair or restoration of the Property so affected, or (3) applied
to the payment of the secured indebtedness in such order and manner as
Mortgagee, in its sole but reasonable discretion, may elect, whether or not due.
In any event the unpaid portion of the secured indebtedness shall remain in full
force and effect and the payment thereof shall not be excused.  Mortgagee shall
not be, under any circumstances, liable or responsible for failure to collect or
to exercise diligence in the collection of any such sum or for failure to see to
the proper application of any amount paid over to Mortgagor.  Mortgagee is
hereby authorized, in the name of Mortgagor, to execute and deliver valid
<PAGE>
 
acquittances for, and to appeal from, any such award, judgment or decree.  All
costs and expenses (including but not limited to attorneys' fees) incurred by
Mortgagee in connection with any condemnation shall be a demand obligation owing
by Mortgagor (which Mortgagor hereby promises to pay) to Mortgagee pursuant to
this Mortgage.

          (g) Compliance with Legal Requirements.  The Property and the use,
              ----------------------------------                            
operation and maintenance thereof and all activities thereon do and shall at all
times comply with all applicable Legal Requirements (defined below).  The
Property is not, and shall not be, dependent on any other property or premises
or any interest therein other than the Property to fulfill any requirement of
any Legal Requirement.  Mortgagor shall not, by act or omission, permit any
building or other improvement not subject to the lien and interest of this
Mortgage to rely on the Property or any interest therein to fulfill any
requirement of any Legal Requirement.  No part of the Property constitutes a
nonconforming use under any zoning law or similar law or ordinance.  Mortgagor
has obtained and shall preserve in force all requisite zoning, utility,
building, parking, health, environmental and operating permits from the
governmental authorities having jurisdiction over the Property.  If Mortgagor
receives a notice or claim from any person that the Property, or any use,
activity, operation or maintenance thereof or thereon, is not in compliance with
any Legal Requirement, Mortgagor will promptly furnish a copy of such notice or
claim to Mortgagee.  Mortgagor has received no notice and has no knowledge of
any such noncompliance.  As used in this Mortgage:  (i) the term "Legal
                                                                  -----
Requirement" means any Law (defined below), agreement, covenant, restriction,
- -----------                                                                  
easement or condition (including, without limitation of the foregoing, any
condition or requirement imposed by any insurance or surety company), as any of
the same now exists or may be changed or amended or come into effect in the
future; and (ii) the term "Law" means any federal, state or local law, statute,
                           ---                                                 
ordinance, code, rule, regulation, license, permit, authorization, decision,
order, injunction or decree, domestic or foreign.

          (h) Maintenance, Repair and Restoration.  Mortgagor will keep the
              -----------------------------------                          
Property in first class order, repair, operating condition and appearance,
causing all necessary repairs, renewals, replacements, additions and
improvements to be promptly made, and will not allow any of the Property to be
misused, abused or wasted or to deteriorate.  The Improvements are directly
connected to abutting public water, sewer, gas, electrical and telephone lines
and pipes (and other necessary utilities) properly operating and in sufficient
capacity with all charges being currently paid.  Notwithstanding the foregoing,
Mortgagor will not, without the prior written consent of Mortgagee, which
consent shall not be unreasonably withheld, (i) remove from the Property any
fixtures or personal property conveyed or encumbered by this Mortgage except
such as is replaced by Mortgagor by an article of equal suitability and value,
owned by Mortgagor, free and clear of any lien or security interest (except that
created by this Mortgage), or (ii) make any structural alteration to the
Property or any other alteration thereto which impairs the value thereof. If any
act or occurrence of any kind or nature (including any condemnation or any
casualty for which insurance was not obtained or obtainable) shall result in
damage to or loss or destruction of the Property, Mortgagor shall give prompt
notice thereof to Mortgagee and Mortgagor shall promptly, at Mortgagor's sole
cost and expense and regardless of whether insurance or condemnation proceeds
(if any) shall be available or sufficient for the purpose, commence and continue
diligently to completion to restore, repair, replace and rebuild the Property as
nearly as possible to its value, condition and character immediately prior to
the damage, loss or destruction.
<PAGE>
 
          (i) No Other Liens.   Mortgagor will not, without the prior written
              --------------                                                 
consent of Mortgagee, create, place or permit to be created or placed, or
through any act or failure to act, acquiesce in the placing of, or allow to
remain, any mortgage, security instrument, voluntary or involuntary lien,
whether statutory, constitutional or contractual, security title, interest,
encumbrance or charge, or conditional sale or other title retention document,
against or covering the Property, or any part thereof, other than the Permitted
Encumbrances, regardless of whether the same are expressly or otherwise
subordinate to the lien or security interest created in this Mortgage, and
should any of the foregoing become attached hereafter in any manner to any part
of the Property without the prior written consent of Mortgagee, Mortgagor will
cause the same to be promptly discharged and released.  Mortgagor will own all
parts of the Property and will not acquire any fixtures, equipment or other
property forming a part of the Property, pursuant to a lease, license, security
agreement or similar agreement, whereby any party has or may obtain the right to
repossess or remove same, without the prior written consent of Mortgagee, which
consent shall not be unreasonably withheld.  If Mortgagee consents to the
voluntary grant by Mortgagor of any mortgage, lien, security interest, or other
encumbrance (hereinafter called "Subordinate Lien") conveying or encumbering any
of the Property or if the foregoing prohibition is determined by a court of
competent jurisdiction to be unenforceable as to a Subordinate Lien, any such
Subordinate Lien shall contain express covenants to the effect that:  (1) the
Subordinate Lien is unconditionally subordinate to this Mortgage and all Leases
(hereinafter defined); (2) if any action (whether judicial or pursuant to a
power of sale) shall be instituted to foreclose or otherwise enforce the
Subordinate Lien, no tenant of any of the Leases (hereinafter defined) shall be
named as a party defendant, and no action shall be taken that would terminate
any occupancy or tenancy without the prior written consent of Mortgagee; (3)
Rents (hereinafter defined), if collected by or for the holder of the
Subordinate Lien, shall be applied first to the payment of the secured
indebtedness then due and expenses incurred in the ownership, operation and
maintenance of the Property in such order as Mortgagee may determine, prior to
being applied to any indebtedness secured by the Subordinate Lien; (4) written
notice of default under the Subordinate Lien and written notice of the
commencement of any action (whether judicial or pursuant to a power of sale) to
foreclose or otherwise enforce the Subordinate Lien or to seek the appointment
of a receiver for all or any part of the Property shall be given to Mortgagee
with or immediately after the occurrence of any such default or commencement;
and (5) neither the holder of the Subordinate Lien, nor any purchaser at
foreclosure thereunder, nor anyone claiming by, through or under any of them
shall succeed to any of Mortgagor's rights hereunder without the prior written
consent of Mortgagee.

          (j) Operation of Property.  Mortgagor will operate the Property in a
              ---------------------                                           
good and workmanlike manner and in accordance with all Legal Requirements and
will pay all fees or charges of any kind in connection therewith.  Mortgagor
will keep the Property occupied so as not to impair the insurance carried
thereon.  Mortgagor will not use or occupy or conduct any activity on, or allow
the use or occupancy of or the conduct of any activity on, the Property in any
manner which violates any Legal Requirement or which constitutes a public or
private nuisance or which makes void, voidable or cancelable, or increases the
premium of, any insurance then in force with respect thereto.  Mortgagor will
not initiate or permit any zoning reclassification of the Property or seek any
variance under existing zoning ordinances applicable to the Property or use or
permit the use of the Property in such a manner which would result in such use
becoming a nonconforming 
<PAGE>
 
use under applicable zoning ordinances or other Legal Requirement. Mortgagor
will not impose any easement, restrictive covenant or encumbrance upon the
Property, execute or file any subdivision plat or condominium declaration
affecting the Property or consent to the annexation of the Property to any
municipality, without the prior written consent of Mortgagee, which consent
shall not be unreasonably withheld. Mortgagor will not do or suffer to be done
any act whereby the value of any part of the Property may be lessened. Mortgagor
will preserve, protect, renew, extend and retain all material rights and
privileges granted for or applicable to the Property. Without the prior written
consent of Mortgagee pursuant to paragraph (u) of this Section 2.1, there shall
be no drilling or exploration for or extraction, removal or production of any
mineral, hydrocarbon, gas, natural element, compound or substance (including
sand and gravel) from the surface or subsurface of the Land regardless of the
depth thereof or the method of mining or extraction thereof. Mortgagor will
cause all debts and liabilities of any character (including without limitation
all debts and liabilities for labor, material and equipment and all debts and
charges for utilities servicing the Property) incurred in the construction,
maintenance, operation and development of the Property to be promptly paid.

          (k) Financial Matters.  Mortgagor is solvent after giving effect to
              -----------------                                              
all borrowings contemplated by the Loan Documents and no proceeding under any
Debtor Relief Law (hereinafter defined) is pending (or, to Mortgagor's
knowledge, threatened) by or against Mortgagor, or any affiliate of Mortgagor,
as a debtor.  All reports, statements, plans, budgets, applications, agreements
and other data and information heretofore furnished or hereafter to be furnished
by or on behalf of Mortgagor to Mortgagee in connection with the loan or loans
evidenced by the Loan Documents (including, without limitation, all financial
statements and financial information) are and will be true, correct and complete
in all material respects as of their respective dates and do not and will not
omit to state any fact or circumstance necessary to make the statements
contained therein not misleading.  No material adverse change has occurred since
the dates of such reports, statements and other data in the financial condition
of Mortgagor or, to Mortgagor's knowledge, of any tenant under any lease
described therein.  For the purposes of this paragraph, "Mortgagor" shall also
include any person liable directly or indirectly for the secured indebtedness or
any part thereof and any joint venturer or general partner of Mortgagor.

          (l) Status of Mortgagor; Suits and Claims; Loan Documents.  Mortgagor
              -----------------------------------------------------            
is and will continue to be (i) duly organized, validly existing and in good
standing under the laws of its state of organization, (ii) authorized to do
business in, and in good standing in, each state in which the Property is
located, and (iii) possessed of all requisite power and authority to carry on
its business and to own and operate the Property.  Each Loan Document executed
by Mortgagor has been duly authorized, executed and delivered by Mortgagor, and
the obligations thereunder and the performance thereof by Mortgagor in
accordance with their terms are and will continue to be within Mortgagor's power
and authority (without the necessity of joinder or consent of any other person),
are not and will not be in contravention of any Legal Requirement or any other
document or agreement to which Mortgagor or the Property is subject, and do not
and will not result in the creation of any encumbrance against any assets or
properties of Mortgagor, or any other person liable, directly or indirectly, for
any of the secured indebtedness, except as expressly contemplated by the Loan
Documents.  There is no suit, action, claim, investigation, inquiry, proceeding
or demand pending (or, to Mortgagor's knowledge, threatened) against Mortgagor
or against any other 
<PAGE>
 
person liable directly or indirectly for the secured indebtedness or which
affects the Property (including, without limitation, any which challenges or
otherwise pertains to Mortgagor's title to the Property) or the validity,
enforceability or priority of any of the Loan Documents. There is no judicial or
administrative action, suit or proceeding pending (or, to Mortgagor's knowledge,
threatened) against Mortgagor or against any other person liable directly or
indirectly for the secured indebtedness, except as has been disclosed in writing
to Mortgagee in connection with the loan evidenced by the Note. The Loan
Documents constitute legal, valid and binding obligations of Mortgagor (and of
each guarantor) enforceable in accordance with their terms, except as the
enforceability thereof may be limited by Debtor Relief Laws (hereinafter
defined) and except as the availability of certain remedies may be limited by
general principles of equity. Mortgagor is not a "foreign person" within the
meaning of the Internal Revenue Code of 1986, as amended, Sections 1445 and 7701
(i.e. Mortgagor is not a non-resident alien, foreign corporation, foreign
partnership, foreign trust or foreign estate as those terms are defined therein
and in any regulations promulgated thereunder). The loan evidenced by the Note
is solely for business purposes, and is not for personal, family, household or
agricultural purposes. Mortgagor will not cause or permit any change to be made
in its name, identity, or corporate or partnership structure, unless Mortgagor
shall have notified Mortgagee of such change prior to the effective date of such
change, and shall have first taken all action required by Mortgagee for the
purpose of further perfecting or protecting the lien and security interest of
Mortgagee in the Property. Mortgagor's principal place of business and chief
executive office, and the place where Mortgagor keeps its books and records
concerning the Property, has for the preceding four months been and will
continue to be (unless Mortgagor notifies Mortgagee of any change in writing
prior to the date of such change) the address of Mortgagor set forth at the end
of this Mortgage.

     any use or activity on the Property, and any claim at any time threatened

                                                         ----

     respect to the Property or adjacent property means "on, in, under, above or
     about".

          (ii)   Representations and Warranties.  Mortgagor represents and
                 ------------------------------                           
     warrants to Mortgagee, without regard to whether Mortgagee has or hereafter
     obtains any knowledge or report of the environmental condition of the
     Property, as follows:  (1) during the period of Mortgagor's ownership of
     the Property, the Property has not been used for industrial or
     manufacturing purposes, for landfill, dumping or other waste disposal
     activity or operation, for generation, storage, use, sale, treatment,
     processing, recycling or disposal of any Hazardous Substance, or for any
     other use that would give rise to the release of any Hazardous Substance on
     the Property; (2) to the best of Mortgagor's knowledge after inquiry in
     accordance with good commercial or customary practices, no use of the
     Property described in clause (1) preceding occurred at any time prior to
     the period of Mortgagor's ownership of the Property nor did any such use on
     any adjacent property occur during or at any time prior to the period of
     Mortgagor's ownership of the Property, and there is no Hazardous Substance,
     storage tank (or similar vessel), sump or well on the Property; (3)
     Mortgagor has received no notice and has no knowledge of any Environmental
     Claim or any completed, pending, proposed or threatened investigation or
     inquiry concerning the presence or release of any Hazardous Substance on
     the Property or on any adjacent property or concerning whether any
     condition, use or activity on the Property or on any adjacent property is
     in violation of any Environmental Requirement; (4) the present conditions,
     uses and activities on the Property do not violate any Environmental
     Requirement and the use of the Property which Mortgagor (and each tenant
     and subtenant, if any) makes and intends to make of the Property complies
     and will comply with all applicable Environmental Requirements; (5) the
     Property is not currently on, and to the best of Mortgagor's knowledge
     after inquiry in accordance with good commercial or customary practices,
     has never been on, any federal or state "superfund" or "superlien" list;
     and (6) neither Mortgagor, nor to Mortgagor's knowledge any tenant or
     subtenant, has obtained or is required to obtain any permit or other
     authorization to construct, occupy, operate, use or conduct any activity on
     any of the Property by reason of any Environmental Requirement.

          (iii)  Violations.  Mortgagor will not cause, commit, permit or allow
                 ----------                                                    
     to continue any violation of any Environmental Requirement by Mortgagor or
     by or with respect to the Property or any use or activity on the Property,
     or the attachment of any environmental lien to the Property.  Mortgagor
     will not place, install, dispose of or release, or cause, permit or allow
     the placing, installation, disposal or release of, any Hazardous Substance
     or storage tank (or similar vessel) on the Property and will keep the
     Property free of any Hazardous 
<PAGE>
 
     Substance. Notwithstanding the foregoing provisions of this Subparagraph
     (iii), Mortgagor shall not be in default under this Subparagraph (iii)
     should Mortgagor store minimal quantities of substances on the Property
     which technically could be considered Hazardous Substances, provided that:
                                                                 -------------
     such substances are of a type and are held only in a quantity normally used
     in connection with the construction, occupancy or operation of comparable
     buildings (such as cleaning fluids, and supplies normally used in the day
     to day operation of business offices), such substances are being held,
     stored and used in complete and strict compliance with all applicable
     Environmental Requirements, and the indemnity in Section 7 of the
     Environmental Agreement shall always apply to such substances, and it shall
     be and continue to be the responsibility of Mortgagor to take all remedial
     actions required under and in accordance with Subparagraph (vi), below, in
     the event of any unlawful release of any such substance.

          (iv) Notice to Mortgagee.  Mortgagor will promptly advise Mortgagee in
               -------------------                                              
     writing of any Environmental Claim or of the discovery of any Hazardous
     Substance on the Property, as soon as Mortgagor first obtains knowledge
     thereof, including a full description of the nature and extent of the
     Environmental Claim and/or Hazardous Substance and all relevant
     circumstances.

          (v)  Site Assessments and Information.  If Mortgagee shall ever have
               --------------------------------                               
     reason to believe that any Hazardous Substance affects the Property, or if
     any Environmental Claim is made or threatened, or if a default shall have
     occurred, Mortgagor will at its expense provide to Mortgagee from time to
     time, in each case within 30 days of Mortgagee's request, a report
     (including all drafts thereof if requested by Mortgagee) of an
     environmental assessment of the Property made after the date of Mortgagee's
     request and of such scope (including but not limited to the taking of soil
     borings, air and groundwater samples and other above and below ground
     testing) as Mortgagee may request and by a consulting firm acceptable to
     Mortgagee.  Mortgagor will cooperate with each consulting firm making any
     such assessment and will supply to the consulting firm, from time to time
     and promptly on request, all information available to Mortgagor to
     facilitate the completion of the assessment and report.

          (vi) Remedial Actions.  Without limitation of Mortgagee's rights to
               ----------------                                              
     declare a default and to exercise all remedies available by reason thereof,
     if any Hazardous Substance is discovered on the Property at any time and
     regardless of the cause, Mortgagor shall: (1) promptly at Mortgagor's sole
     risk and expense remove, treat and dispose of the Hazardous Substance in
     compliance with all applicable Environmental Requirements and solely under
     Mortgagor's name (or if removal is prohibited by any Environmental
     Requirement, take whatever action is required by applicable Environmental
     Requirements), in addition to taking such other action as is necessary to
     have the full use and benefit of the Property as contemplated by the Loan
     Documents, and provide Mortgagee with satisfactory evidence thereof; and
     (2) if requested by Mortgagee, provide to Mortgagee within 30 days of
     Mortgagee's request a bond, letter of credit or other financial assurance
     evidencing to Mortgagee's satisfaction that all necessary funds are readily
     available to pay the costs and expenses of the actions required by clause
     (1) preceding and to discharge any assessments 
<PAGE>
 
     or liens established against the Property as a result of the presence of
     the Hazardous Substance on the Property.

     (n)  Further Assurances. Mortgagor will, promptly on request of Mortgagee,
          ------------------          
(i) correct any defect, error or omission which may be discovered in the
contents, execution or acknowledgment of this Mortgage or any other Loan
Document; (ii) execute, acknowledge, deliver, procure and record and/or file
such further documents (including, without limitation, further mortgages,
security agreements, financing statements, continuation statements, and
assignments of rents or leases) and do such further acts as may be necessary,
desirable or proper to carry out more effectively the purposes of this Mortgage
and the other Loan Documents, to more fully identify and subject to the liens
and interests hereof any property intended to be covered hereby (including
specifically, but without limitation, any renewals, additions, substitutions,
replacements, or appurtenances to the Property) or as deemed advisable by
Mortgagee to protect the lien or the interest hereunder against the rights or
interests of third persons; and (iii) provide such certificates, documents,
reports, information, affidavits and other instruments and do such further acts
as may be necessary, desirable or proper in the reasonable determination of
Mortgagee to enable Mortgagee to comply with the requirements or requests of any
agency having jurisdiction over Mortgagee or any examiners of such agencies with
respect to the indebtedness secured hereby, Mortgagor or the Property. Mortgagor
shall pay all costs connected with any of the foregoing, which shall be a demand
obligation owing by Mortgagor (which Mortgagor hereby promises to pay) to
Mortgagee pursuant to this Mortgage.

     (o)  Fees and Expenses.  Without limitation of any other provision of
          -----------------                                               
this Mortgage or of any other Loan Document and to the extent not prohibited by
applicable law, Mortgagor will pay, and will reimburse to Mortgagee on demand to
the extent paid by Mortgagee: (i) all appraisal fees, filing and recording fees,
taxes, brokerage fees and commissions, abstract fees, title search or
examination fees, title policy and endorsement premiums and fees, uniform
commercial code search fees, escrow fees, reasonable attorneys' fees, architect
fees, construction consultant fees, environmental inspection fees, survey fees,
and all other out-of-pocket costs and expenses of every character incurred by
Mortgagor or Mortgagee in connection with the preparation of the Loan Documents,
the evaluation, closing and funding of the loan evidenced by the Loan Documents,
and any and all amendments and supplements to this Mortgage, the Note or any
other Loan Documents or any approval, consent, waiver, release or other matter
requested or required hereunder or thereunder, or otherwise attributable or
chargeable to Mortgagor as owner of the Property; and (ii) all costs and
expenses, including reasonable attorneys' fees and expenses, incurred or
expended in connection with the exercise of any right or remedy, or the
enforcement of any obligation of Mortgagor, hereunder or under any other Loan
Document.
<PAGE>
 
     (p)  Indemnification.
          --------------- 

          (i) Mortgagor will indemnify and hold harmless Mortgagee from and
     against, and reimburse Mortgagee on demand for, any and all Indemnified
     Matters (defined below).  For purposes of this paragraph (p), the term
     "Mortgagee" shall include the directors, officers, partners, employees and
     agents of Mortgagee, and any persons owned or controlled by, owning or
     controlling, or under common control or affiliated with Mortgagee.  Without
     limitation, the foregoing indemnities shall apply to each indemnified
     person with respect to matters which in whole or in part are caused by or
     arise out of the negligence of such (and/or any other) indemnified person.
     However, such indemnities shall not apply to a particular indemnified
     person to the extent that the subject of the indemnification is caused by
     or arises out of the gross negligence or willful misconduct of that
     indemnified person.  Any amount to be paid under this paragraph (p) by
     Mortgagor to Mortgagee shall be a demand obligation owing by Mortgagor
     (which Mortgagor hereby promises to pay) to Mortgagee pursuant to this
     Mortgage.  Nothing in this paragraph, elsewhere in this Mortgage or in any
     other Loan Document shall limit or impair any rights or remedies of
     Mortgagee (including without limitation any rights of contribution or
     indemnification) against Mortgagor or any other person under any other
     provision of this Mortgage, any other Loan Document, any other agreement or
     any applicable Legal Requirement.

          (ii) As used herein, the term "Indemnified Matters" means any and all
                                         -------------------                   
     claims, demands, liabilities (including strict liability), losses, damages
     (including consequential damages), causes of action, judgments, penalties,
     costs and expenses (including without limitation, reasonable fees and
     expenses of attorneys and other professional consultants and experts, and
     of the investigation and defense of any claim, whether or not such claim is
     ultimately defeated, and the settlement of any claim or judgment including
     all value paid or given in settlement) of every kind, known or unknown,
     foreseeable or unforeseeable, which may be imposed upon, asserted against
     or incurred or paid by Mortgagee at any time and from time to time,
     whenever imposed, asserted or incurred, because of, resulting from, in
     connection with, or arising out of any transaction, act, omission, event or
     circumstance in any way connected with the Property or with this Mortgage
     or any other Loan Document, including but not limited to any bodily injury
     or death or property damage occurring in or upon or in the vicinity of the
     Property through any cause whatsoever at any time on or before the Release
     Date, any act performed or omitted to be performed hereunder or under any
     other Loan Document, any breach by Mortgagor of any representation,
     warranty, covenant, agreement or condition contained in this Mortgage or in
     any other Loan Document, any default as defined herein or any claim under
     or with respect to any Lease (hereinafter defined), or arising under the
     Environmental Agreement.

     The term "Release Date" as used herein means the earlier of the following
               ------------                                         
     two dates: (i) the date on which the indebtedness and obligations secured
     hereby have been paid and performed in full and this Mortgage has been
     cancelled and satisfied of record, or (ii) the date on which this Mortgage
     is fully and finally foreclosed or a conveyance by deed in lieu of such
     foreclosure is fully and finally effective, and possession of the Property
     has been given to the purchaser or grantee free of occupancy and claims to
     occupancy by Mortgagor 
<PAGE>
 
     and Mortgagor's heirs, devisees, representatives, successors and assigns;
     provided, that if such payment, performance, release, foreclosure or
     conveyance is challenged, in bankruptcy proceedings or otherwise, the
     Release Date shall be deemed not to have occurred until such challenge is
     rejected, dismissed or withdrawn with prejudice. The indemnities in this
     paragraph (p) shall not terminate upon the Release Date or upon the
     cancellation, satisfaction, foreclosure or other termination of this
     Mortgage but will survive the Release Date, foreclosure of this Mortgage or
     conveyance in lieu of foreclosure, the repayment of the secured
     indebtedness, the discharge, cancellation and satisfaction of this Mortgage
     and the other Loan Documents, any bankruptcy or other debtor relief
     proceeding, and any other event whatsoever.

     (q)  Records and Financial Reports.  Mortgagor will keep accurate books
          -----------------------------                                     
and records in accordance with sound accounting principles in which full, true
and correct entries shall be promptly made with respect to the Property and the
operation thereof, and will permit all such books and records to be inspected
and copied, and the Property to be inspected and photographed, by Mortgagee and
its representatives during normal business hours and at any other reasonable
times.  Without limitation of other or additional requirements in any of the
other Loan Documents, Mortgagor will furnish to Mortgagee current operating
statements itemizing all income and expenses of the Property, for each quarter
(and for the fiscal year through the end of such quarter) as soon as reasonably
practicable but in any event within fifteen (15) days after the end of such
quarter and for the fiscal year of Mortgagor within sixty (60) days after the
end thereof including also a projection of such operations for the next fiscal
year; (ii) a balance sheet (including disclosure of all contingent liabilities)
and an income statement of Mortgagor, for each fiscal year of Mortgagor as soon
as reasonably practicable following the end of such fiscal year, but in any
event within ninety (90) days after the end thereof.  Each financial statement
submitted pursuant to this paragraph shall be prepared in accordance with
generally accepted accounting principles, consistently applied, and be certified
in writing as true and correct by a representative of Mortgagor acceptable to
Mortgagee.  Mortgagor will furnish to Mortgagee at Mortgagor's expense all
evidence which Mortgagee may from time to time reasonably request as to
compliance with all provisions of the Loan Documents.  Any inspection or audit
of the Property or the books and records of Mortgagor, or the procuring of
documents and financial and other information, by or on behalf of Mortgagee
shall be for Mortgagee's protection only, and shall not constitute any
assumption of responsibility to Mortgagor or anyone else with regard to the
condition, construction, maintenance or operation of the Property nor
Mortgagee's approval of any certification given to Mortgagee nor relieve
Mortgagor of any of Mortgagor's obligations.  Mortgagee may from time to time
assign or grant participations in the secured indebtedness and Mortgagor
consents to the delivery by Mortgagee to any acquirer or prospective acquirer of
any interest or participation in or with respect to all or part of the secured
indebtedness such information as Mortgagee now or hereafter has relating to the
Property, Mortgagor, any party obligated for payment of any part of the secured
indebtedness, any tenant or guarantor under any lease affecting any part of the
Property and any agent or guarantor under any management agreement affecting any
part of the Property.

     (r)  Taxes on Note or Mortgage. Mortgagor will promptly pay all income,
          -------------------------    
franchise and other taxes owing by Mortgagor and any stamp taxes or other taxes
(unless such payment by Mortgagor is prohibited by law) which may be required to
be paid with respect to the Note, this
<PAGE>
 
Mortgage or any other instrument evidencing or securing any of the secured
indebtedness. In the event of the enactment after this date of any law of any
governmental entity applicable to Mortgagee, the Note, the Property or this
Mortgage deducting from the value of property for the purpose of taxation any
lien or interest thereon, or imposing upon Mortgagee the payment of the whole or
any part of the taxes or assessments or charges or liens herein required to be
paid by Mortgagor, or changing in any way the laws relating to the taxation of
mortgages or security agreements or debts secured by mortgages or security
agreements or the interest of the mortgagee or secured party in the property
covered thereby, or the manner of collection of such taxes, so as to affect this
Mortgage or the indebtedness secured hereby or Mortgagee, then, and in any such
event, Mortgagor, upon demand by Mortgagee, shall pay such taxes, assessments,
charges or liens, or reimburse Mortgagee therefor; provided, however, that if in
the opinion of counsel for Mortgagee (i) it might be unlawful to require
Mortgagor to make such payment or (ii) the making of such payment might result
in the imposition of interest beyond the maximum amount permitted by law, then
and in such event, Mortgagee may elect, by notice in writing given to Mortgagor,
to declare all of the indebtedness secured hereby to be and become due and
payable sixty (60) days from the giving of such notice.

          (s) Statement Concerning Note or Mortgage.  Mortgagor shall at any
              -------------------------------------                         
time and from time to time furnish within seven (7) days of request by Mortgagee
a written statement in such form as may be required by Mortgagee stating that
(i) the Note, this Mortgage and the other Loan Documents are valid and binding
obligations of Mortgagor, enforceable against Mortgagor in accordance with their
terms; (ii) the unpaid principal balance of the Note; (iii) the date to which
interest on the Note is paid; (iv) the Note, this Mortgage and the other Loan
Documents have not been released, subordinated or modified; and (v) there are no
offsets or defenses against the enforcement of the Note, this Mortgage or any
other Loan Document.  If any of the foregoing statements are untrue, Mortgagor
shall, alternatively, specify the reasons therefor.

          (t) Annual Appraisal.  Mortgagee may at its option obtain at
              ----------------                                        
Mortgagor's expense, once in each year (or as otherwise reasonably requested by
Mortgagee) an appraisal of the Property or any part thereof prepared in
accordance with written instructions from Mortgagee by a third-party appraiser
engaged directly by Mortgagee.  Each such appraiser and appraisal shall be
satisfactory to Mortgagee.  The costs of each such appraisal shall be a part of
the secured indebtedness and shall be payable by Mortgagor to Mortgagee on
demand (which obligation Mortgagor hereby promises to pay).

          (u) Mineral Interests.  Mortgagor agrees that the making of any oil,
              -----------------                                               
gas or mineral lease or the sale or conveyance of any mineral interest or right
to explore for minerals under, through or upon the Property would impair the
value of the Property as security for payment of the indebtedness secured hereby
and that Mortgagor shall have no right, power or authority to lease the
Property, or any part thereof, for oil, gas or other mineral purposes, or to
grant, assign or convey any mineral interest of any nature, or the right to
explore for oil, gas and other minerals, without first obtaining from Mortgagee
express written permission, which permission shall not be valid until recorded.
Mortgagor further agrees that if Mortgagor shall make any such lease or attempt
to grant any such mineral rights without such prior written permission, then
Mortgagee shall have the option, without notice, to declare the same to be a
default hereunder 
<PAGE>
 
and to declare the indebtedness secured hereby immediately due and payable.
Whether or not Mortgagee shall consent to such lease or grant of mineral rights,
Mortgagee shall receive the entire consideration to be paid for such lease or
grant of mineral rights, with the same to be applied upon the indebtedness
secured hereby; provided, however, that the acceptance of such consideration
shall in no way impair the lien of this Mortgage on the Property, including all
mineral rights.

          (v) Year 2000 Compliance.  Mortgagor has (i) initiated a review and
              --------------------                                           
assessment of all areas within its business and operations (including those
affected by suppliers and vendors) that could be adversely affected by the "Year
                                                                            ----
2000 Problem" (that is, the risk that computer applications used by Mortgagor
- ------------                                                                 
(or its suppliers and vendors) may be unable to recognize and perform properly
date-sensitive functions involving certain dates prior to and any date after
December 31, 1999), (ii) developed a plan and timeline for addressing the Year
2000 Problem on a timely basis, and (iii) to date, implemented that plan in
accordance with that timetable.  Mortgagor reasonably believes that all computer
applications (including those of its suppliers and vendors) that are material to
its business and operations will on a timely basis be able to perform properly
date-sensitive functions for all dates before and after January 1, 2000 (that
is, will be "Year 2000 Compliant"), except to the extent that a failure to do so
             -------------------                                                
could not reasonably be expected to cause a material adverse change in the
financial condition, results of operations, business or properties of Mortgagor
(a "Material Adverse Change").  Mortgagor will promptly notify Mortgagee in the
    -----------------------                                                    
event that Mortgagor discovers or determines that any computer application
(including those of its suppliers and vendors) that is material to its business
and operations will not be Year 2000 Compliant on a timely basis, except to the
extent that such failure could not reasonably be expected to cause a Material
Adverse Change.

          Section 2.2.  Performance by Mortgagee on Mortgagor's Behalf.
                        ---------------------------------------------- 
Mortgagor agrees that, if Mortgagor fails to perform any act or to take any
action which under any Loan Document Mortgagor is required to perform or take,
or to pay any money which under any Loan Document Mortgagor is required to pay,
and whether or not the failure then constitutes a default hereunder or
thereunder, and whether or not there has occurred any default or defaults
hereunder or the secured indebtedness has been accelerated, Mortgagee, in
Mortgagor's name or its own name, may, but shall not be obligated to, perform or
cause to be performed such act or take such action or pay such money, and any
expenses so incurred by Mortgagee and any money so paid by Mortgagee shall be a
demand obligation owing by Mortgagor to Mortgagee (which obligation Mortgagor
hereby promises to pay), shall be a part of the indebtedness secured hereby, and
Mortgagee, upon making such payment, shall be subrogated to all of the rights of
the person, entity or body politic receiving such payment.  Mortgagee and its
designees shall have the right to enter upon the Property at any time and from
time to time for any such purposes.  No such payment or performance by Mortgagee
shall waive or cure any default or waive any right, remedy or recourse of
Mortgagee.  Any such payment may be made by Mortgagee in reliance on any
statement, invoice or claim without inquiry into the validity or accuracy
thereof.  Each amount due and owing by Mortgagor to Mortgagee pursuant to this
Mortgage shall bear interest, from the date such amount becomes due until paid,
at the rate per annum provided in the Note for interest on past due principal
owed on the Note but never in excess of the maximum nonusurious amount permitted
by applicable law, which interest shall be payable to Mortgagee on demand; and
all such amounts, together with such interest 
<PAGE>
 
thereon, shall automatically and without notice be a part of the indebtedness
secured hereby. The amount and nature of any expense by Mortgagee hereunder and
the time when paid shall be fully established by the certificate of Mortgagee or
any of Mortgagee's officers or agents.

          Section 2.3.  Absence of Obligations of Mortgagee with Respect to
                        ---------------------------------------------------
Property.  Notwithstanding anything in this Mortgage to the contrary, including,
- --------                                                                        
without limitation, the definition of "Property" and/or the provisions of
Article 3 hereof, (i) to the extent permitted by applicable law, the Property is
composed of Mortgagor's rights, title and interests therein but not Mortgagor's
obligations, duties or liabilities pertaining thereto, (ii) Mortgagee neither
assumes nor shall have any obligations, duties or liabilities in connection with
any portion of the items described in the definition of "Property" herein,
either prior to or after obtaining title to such Property, whether by
foreclosure sale, the granting of a deed in lieu of foreclosure or otherwise,
and (iii) Mortgagee may, at any time prior to or after the acquisition of title
to any portion of the Property as above described, advise any party in writing
as to the extent of Mortgagee's interest therein and/or expressly disaffirm in
writing any rights, interests, obligations, duties and/or liabilities with
respect to such Property or matters related thereto.  Without limiting the
generality of the foregoing, it is understood and agreed that Mortgagee shall
have no obligations, duties or liabilities prior to or after acquisition of
title to any portion of the Property, as lessee under any lease or purchaser or
seller under any contract or option unless Mortgagee elects otherwise by written
notification.

             ARTICLE 3 - COLLATERAL ASSIGNMENT OF LEASES AND RENTS
                         -----------------------------------------

          Section 3.1.  Assignment.  As additional security for the indebtedness
                        -----------                                             
secured hereby, Mortgagor hereby assigns to Mortgagee all Rents (hereinafter
defined) and all of Mortgagor's rights in and under all Leases (hereinafter
defined).  Upon the occurrence of a default hereunder, Mortgagee shall have the
right, power and privilege (but shall be under no duty) to demand possession of
the Rents, which demand shall to the fullest extent permitted by applicable law
be sufficient action by Mortgagee to entitle Mortgagee to immediate and direct
payment of the Rents (including delivery to Mortgagee of Rents collected for the
period in which the demand occurs and for any subsequent period), for
application as provided in Section 5.2 of this Mortgage, all without the
necessity of any further action by Mortgagee, including, without limitation, any
action to obtain possession of the Land, Improvements or any other portion of
the Property or any action for the appointment of a receiver.  Mortgagor hereby
authorizes and directs the tenants under the Leases to pay Rents to Mortgagee
upon written demand by Mortgagee, without further consent of Mortgagor, without
any obligation to determine whether a default has in fact occurred and
regardless of whether Mortgagee has taken possession of any portion of the
Property, and the tenants may rely upon any written statement delivered by
Mortgagee to the tenants.  Any such payment to Mortgagee shall constitute
payment to Mortgagor under the Leases, and Mortgagor hereby appoints Mortgagee
as Mortgagor's lawful attorney-in-fact for giving, and Mortgagee is hereby
empowered to give, acquittances to any tenants for such payments to Mortgagee
after a default.  The assignment contained in this Section shall become null and
void upon the release of this Mortgage.  As used herein: (i) "Lease" means each
                                                              -----            
existing or future lease, sublease (to the extent of Mortgagor's rights
thereunder), usufruct or other agreement under the terms of which any person has
or acquires any right to occupy or use the Property, or any part thereof, or
interest therein, and each existing or future guaranty of payment or performance
thereunder, and all extensions, renewals, modifications 
<PAGE>
 
and replacements of each such lease, sublease, usufruct, agreement or guaranty;
and (ii) "Rents" means all of the rents, revenue, income, profits and proceeds
          -----
derived and to be derived from the Property or arising from the use or enjoyment
of any portion thereof or from any Lease, including but not limited to
liquidated damages following default under any such Lease, all proceeds payable
under any policy of insurance covering loss of rents resulting from
untenantability caused by damage to any part of the Property, all of Mortgagor's
rights to recover monetary amounts from any tenant in bankruptcy including,
without limitation, rights of recovery for use and occupancy and damage claims
arising out of Lease defaults, including rejections, under any applicable Debtor
Relief Law (as hereinafter defined), together with any sums of money that may
now or at any time hereafter be or become due and payable to Mortgagor by virtue
of any and all royalties, overriding royalties, bonuses, delay rentals and any
other amount of any kind or character arising under any and all present and all
future oil, gas, mineral and mining leases covering the Property or any part
thereof, and all proceeds and other amounts paid or owing to Mortgagor under or
pursuant to any and all contracts and bonds relating to the construction or
renovation of the Property.

          Section 3.2.  Covenants, Representations and Warranties Concerning
                        ----------------------------------------------------
Leases and Rents.  Mortgagor covenants, represents and warrants that:  (i)
- ----------------                                                          
Mortgagor has good title to, and is the owner of the entire landlord's interest
in, the Leases and Rents hereby assigned and authority to assign them;  (ii) all
Leases are valid and enforceable, and in full force and effect, and are
unmodified except as stated therein; (iii) neither Mortgagor nor any tenant in
the Property is in default under its Lease (and no event has occurred which with
the passage of time or notice or both would result in a default under its Lease)
or is the subject of any bankruptcy, insolvency or similar proceeding; (iv)
unless otherwise stated in a Permitted Encumbrance, no Rents or Leases have been
or will be assigned, mortgaged, pledged or otherwise encumbered and no other
person has or will acquire any right, title or interest in such Rents or Leases;
(v) no Rents have been waived, released, discounted, set off or compromised;
(vi) except as stated in the Leases, Mortgagor has not received any funds or
deposits from any tenant for which credit has not already been made on account
of accrued Rents; (vii) Mortgagor shall perform all of its obligations under the
Leases and enforce the tenants' obligations under the Leases to the extent
enforcement is prudent under the circumstances; (viii) Mortgagor will not
without the prior written consent of Mortgagee (which consent shall not be
unreasonably withheld), enter into any Lease after the date hereof, or waive,
release, discount, set off, compromise, reduce or defer any Rent, receive or
collect Rents more than one (1) month in advance, grant any rent-free period to
any tenant, reduce any Lease term or waive, release or otherwise modify any
other material obligation under any Lease, renew or extend any Lease except in
accordance with a right of the tenant thereto in such Lease, approve or consent
to an assignment of a Lease or a subletting of any part of the premises covered
by a Lease, or settle or compromise any claim against a tenant under a Lease in
bankruptcy or otherwise; (ix) Mortgagor will not, except in good faith where the
tenant is in material default thereunder, terminate or consent to the
cancellation or surrender of any Lease having an unexpired term of one year or
more unless promptly after the cancellation or surrender a new Lease of such
premises is made with a new tenant, having a credit standing, in Mortgagee's
judgment, at least equivalent to that of the tenant whose Lease was cancelled,
on substantially the same terms as the terminated or cancelled Lease; (x)
Mortgagor will not execute any Lease except in accordance with the Loan
Documents and for actual occupancy by the tenant thereunder; (xi) Mortgagor
shall give prompt notice to Mortgagee, as soon as Mortgagor first obtains
notice, of any claim, or the commencement of any action, by any 
<PAGE>
 
tenant or subtenant under or with respect to a Lease regarding any claimed
damage, default, diminution of or offset against Rent, cancellation of the
Lease, or constructive eviction, and Mortgagor shall defend, at Mortgagor's
expense, any proceeding pertaining to any Lease, including, if Mortgagee so
requests, any such proceeding to which Mortgagee is a party; (xii) Mortgagor
shall as often as requested by Mortgagee, within ten (10) days of each request,
deliver to Mortgagee a complete rent roll of the property in such detail as
Mortgagee may require and financial statements of the tenants, subtenants and
guarantors under the Leases to the extent available to Mortgagor, and deliver to
such of the tenants and others obligated under the Leases specified by Mortgagee
written notice of the assignment in Section 3.1 hereof in form and content
satisfactory to Mortgagee; (xiii) promptly upon request by Mortgagee, Mortgagor
shall deliver to Mortgagee executed originals of all Leases and copies of all
records relating thereto; (xiv) there shall be no merger of the leasehold
estates, created by the Leases, with the fee estate of the Land without the
prior written consent of Mortgagee; and (xv) Mortgagee may at any time and from
time to time by specific written instrument intended for the purpose,
unilaterally subordinate the lien of this Mortgage to any Lease, without joinder
or consent of, or notice to, Mortgagor, any tenant or any other person, and
notice is hereby given to each tenant under a Lease of such right to
subordinate. No such subordination shall constitute a subordination to any lien
or other encumbrance, whenever arising, or improve the right of any junior
lienholder; and nothing herein shall be construed as subordinating this Mortgage
to any Lease.

          Section 3.3.  No Liability of Mortgagee.  Mortgagee's acceptance of
                        -------------------------                            
this assignment shall not be deemed to constitute Mortgagee a "mortgagee in
possession," nor obligate Mortgagee to appear in or defend any proceeding
relating to any Lease or to the Property, or to take any action hereunder,
expend any money, incur any expenses, or perform any obligation or liability
under any Lease, or assume any obligation for any deposit delivered to Mortgagor
by any tenant and not as such delivered to and accepted by Mortgagee.  Mortgagee
shall not be liable for any injury or damage to person or property in or about
the Property, or for Mortgagee's failure to collect or to exercise diligence in
collecting Rents, but shall be accountable only for Rents that it shall actually
receive.  Neither the assignment of Leases and Rents nor enforcement of
Mortgagee's rights regarding Leases and Rents (including collection of Rents)
nor possession of the Property by Mortgagee nor Mortgagee's consent to or
approval of any Lease (nor all of the same), shall render Mortgagee liable on
any obligation under or with respect to any Lease or constitute affirmation of,
or any subordination to, any Lease, occupancy, use or option.  If Mortgagee
seeks or obtains any judicial relief regarding Rents or Leases, the same shall
in no way prevent the concurrent or subsequent employment of any other
appropriate rights or remedies nor shall same constitute an election of judicial
relief for any foreclosure or any other purpose.  Mortgagee neither has nor
assumes any obligations as lessor or landlord with respect to any Lease.  The
rights of Mortgagee under this Article 3 shall be cumulative of all other rights
of Mortgagee under the Loan Documents or otherwise.

(S) 8143 electing to limit the indebtedness secured hereby.
<PAGE>
 
          Section 4.2.  Notice and Cure.  Mortgagee agrees, by its acceptance of
                        ---------------                                         
this Mortgage, that notwithstanding anything to the contrary contained herein or
in any of the other Loan Documents, upon the occurrence of any default of the
type described in Subparagraphs (a) or (b) of Section 4.1 of this Mortgage,
Mortgagee will not accelerate the maturity of the Note or the secured
indebtedness and will not exercise any of its other rights and remedies
hereunder or under the other Loan Documents until and unless Mortgagee has first
given notice of such default to Mortgagor, in the manner prescribed in Section
6.13 of this Mortgage, and Mortgagor has failed to cure such default within the
following periods of time:

          (a)  If such default is a default of the type described in
Subparagraph (a) of Section 4.1 of this Mortgage, Mortgagor shall have a period
of ten (10) days from and after the effective date of such notice within which

notice thereof by Mortgagee, Mortgagee shall not be obligated to give to
Mortgagor any further notice of default or opportunity to cure the same.  The
agreements set forth in this Section 4.2 do not and shall not be deemed to
prevent or prohibit Mortgagee from withholding any advances of the secured
indebtedness, following the occurrence of a default, until and unless such
default shall have been cured.

          If Mortgagee shall fail to give such notice and right to cure to
Mortgagor, as provided herein, the sole and exclusive remedy of Mortgagor for
such failure shall be to seek appropriate equitable relief to enforce the
agreement to give such notice and right to cure and to have any acceleration of
the maturity of the Note and the secured indebtedness postponed or revoked and
foreclosure or other proceedings in connection therewith delayed or terminated
pending or upon the curing of such default in the manner and during the period
of time permitted by such agreement, and Mortgagor shall have no right to
damages or any other type of relief not herein specifically set out against
Mortgagee, all of which damages or other relief are hereby waived by Mortgagor.
Nothing herein or in any of the other Loan Documents shall operate or be
construed to add on or make cumulative any cure or grace periods specified in
any of the Loan Documents.

                        ----------------                                      
may (but shall have no obligation to) exercise any one or more of the following
remedies, without additional notice (unless notice is required by applicable
statute):

          (a)  Acceleration.  Mortgagee may at any time and from time to time
               ------------                                                  
declare any or all of the secured indebtedness immediately due and payable and
such secured indebtedness shall thereupon be immediately due and payable,
without presentment, demand, protest, notice of protest, notice of acceleration
or of intention to accelerate or any other notice or declaration of any kind,

<PAGE>
 
of which are hereby expressly waived by Mortgagor. Without limitation of the
foregoing, upon the occurrence of a default described in clauses (i), (iii) or
(iv) of subparagraph (1) of paragraph (d) of Section 4.1, hereof, all of the
secured indebtedness shall thereupon be immediately due and payable, without

          (b)  Enforcement of Assignment of Rents. Prior or subsequent to taking
               ----------------------------------

          (c)  Foreclosure.  When the secured indebtedness or any part thereof
               -----------                                                    
shall become due, whether by acceleration or otherwise, Mortgagee may (i)
institute and maintain an action of mortgage foreclosure against the Property
and the interests of Mortgagor therein, (ii) institute and maintain an action on
any instrument evidencing the secured indebtedness or any portion thereof, and
(iii) take such other action at law or in equity for the enforcement of any of
the Loan Documents as the law may allow, and in each such action Mortgagee shall
be entitled to all costs of suit and attorneys fees.  In the case of any sale
under this Mortgage by virtue of the exercise of the powers herein granted, or
pursuant to any order in any judicial proceedings or otherwise, at the election
of Mortgagee, the Property or any part thereof may be sold in one parcel and as
an entirety, or in such parcels, manner or order as Mortgagee in its sole
discretion may elect, and one or more exercises of the powers herein granted
shall not extinguish or exhaust the power unless the entire Property is sold or
the secured indebtedness is paid in full.

          (d)  Uniform Commercial Code. Without limitation of Mortgagee's rights
               -----------------------    
of enforcement with respect to the Collateral or any part thereof in accordance
with the procedures for foreclosure of real estate, Mortgagee may exercise its
rights of enforcement with respect to the Collateral or any part thereof under
the Uniform Commercial Code of Pennsylvania (or under the Uniform Commercial
Code in force in any other state to the extent the same is applicable law) and
in conjunction with, in addition to or in substitution for those rights and
remedies: (1) Mortgagee may enter upon Mortgagor's premises to take possession
of, assemble and collect the Collateral or, to the extent and for those items of
the Collateral permitted under applicable law, to render it unusable; (2)
Mortgagee may require Mortgagor to assemble the Collateral and make it available
at a place Mortgagee designates which is mutually convenient to allow Mortgagee
to take possession or dispose of the Collateral; (3) written notice mailed to
Mortgagor as provided herein at least five (5) days prior to the date of public
sale of the Collateral or prior to the date after which private sale of the
Collateral will be made shall constitute reasonable notice; (4) any sale made
pursuant to the provisions of this paragraph shall be deemed to have been a
public sale conducted in a commercially reasonable manner if held
contemporaneously with and upon the same notice as required for the sale of the
Property under power of sale as provided in paragraph (c) above in this
<PAGE>
 
Section 5.1; (5) in the event of a foreclosure sale, whether made by Mortgagee
under the terms hereof, or under judgment of a court, the Collateral and the
other Property may, at the option of Mortgagee, be sold as a whole; (6) it shall
not be necessary that Mortgagee take possession of the Collateral or any part
thereof prior to the time that any sale pursuant to the provisions of this
Section is conducted and it shall not be necessary that the Collateral or any
part thereof be present at the location of such sale; (7) with respect to
application of proceeds of disposition of the Collateral under Section 5.2
hereof, the costs and expenses incident to disposition shall include the
reasonable expenses of retaking, holding, preparing for sale or lease, selling,
leasing and the like and the reasonable attorneys' fees and legal expenses
incurred by Mortgagee; (8) any and all statements of fact or other recitals made
in any bill of sale or assignment or other instrument evidencing any foreclosure
sale hereunder as to nonpayment of the secured indebtedness or as to the
occurrence of any default, or as to Mortgagee's having declared all of such
indebtedness to be due and payable, or as to notice of time, place and terms of
sale and of the properties to be sold having been duly given, or as to any other
act or thing having been duly done by Mortgagee, shall be taken as prima facie
evidence of the truth of the facts so stated and recited; and (9) Mortgagee may
appoint or delegate any one or more persons as agent to perform any act or acts
necessary or incident to any sale held by Mortgagee, including the sending of
notices and the conduct of the sale, but in the name and on behalf of Mortgagee.

          (e)  Lawsuits.  Mortgagee may proceed by a suit or suits in equity or
               --------                                                        
at law, whether for collection of the indebtedness secured hereby, the specific
performance of any covenant or agreement herein contained or in aid of the
execution of any power herein granted, or for any foreclosure hereunder or for
the sale of the Property under the judgment or decree of any court or courts of
competent jurisdiction.

          (f)  Entry on Property.  Mortgagee is authorized, prior or subsequent
               -----------------                                               
to the institution of any foreclosure proceedings, to the fullest extent
permitted by applicable law, to enter upon the Property, or any part thereof,
and to take possession of the Property and all books and records relating
thereto, and to exercise without interference from Mortgagor any and all rights
which Mortgagor has with respect to the management, possession, operation,
protection or preservation of the Property.  Mortgagee shall not be deemed to
have taken possession of the Property or any part thereof except upon the
exercise of its right to do so, and then only to the extent evidenced by its
demand and overt act specifically for such purpose.  All costs, expenses and
liabilities of every character incurred by Mortgagee in managing, operating,
maintaining, protecting or preserving the Property shall constitute a demand
obligation of Mortgagor (which obligation Mortgagor hereby promises to pay) to
Mortgagee pursuant to this Mortgage.  If necessary to obtain the possession
provided for above, Mortgagee may invoke any and all legal remedies to
dispossess Mortgagor.  In connection with any action taken by Mortgagee pursuant
to this Section, Mortgagee shall not be liable for any loss sustained by
Mortgagor resulting from any failure to let the Property or any part thereof, or
from any act or omission of Mortgagee in managing the Property, unless such loss
is caused by the willful misconduct and bad faith of Mortgagee, nor shall
Mortgagee be obligated to perform or discharge any obligation, duty or liability
of Mortgagor arising under any lease or other agreement relating to the Property
or arising under any Permitted Encumbrance or otherwise arising.  Mortgagor
hereby assents to, ratifies and confirms any and all actions of Mortgagee with
respect to the Property taken under this Section.
<PAGE>
 
          (g)  Receiver. Mortgagee shall as a matter of right be entitled to the
               --------
appointment of a receiver or receivers for all or any part of the Property,
whether such receivership be incident to a proposed sale (or sales) of such
property or otherwise, and without regard to the value of the Property or the
solvency of any person or persons liable for the payment of the indebtedness
secured hereby, and Mortgagor does hereby irrevocably consent to the appointment
of such receiver or receivers, waives any and all defenses to such appointment,
agrees not to oppose any application therefor by Mortgagee, and agrees that such
appointment shall in no manner impair, prejudice or otherwise affect the rights
of Mortgagee to application of Rents as provided in this Mortgage. Nothing
herein is to be construed to deprive Mortgagee of any other right, remedy or
privilege it may have under the law to have a receiver appointed. Any money
advanced by Mortgagee in connection with any such receivership shall be a demand
obligation (which obligation Mortgagor hereby promises to pay) owing by
Mortgagor to Mortgagee pursuant to this Mortgage.

          (h)  Termination of Commitment to Lend.  Mortgagee may terminate any
               ---------------------------------                              
commitment or obligation to lend or disburse funds under any Loan Document.

          (i)  Other Rights and Remedies.  Mortgagee may exercise any and all
               -------------------------                                     
other rights and remedies which Mortgagee may have under the Loan Documents, or
at law or in equity or otherwise.

          Section 5.2.  Proceeds of Foreclosure.  The proceeds of any sale held
                        -----------------------                                
by Mortgagee or any receiver of the liens and interests evidenced hereby shall
be applied:  FIRST, to the payment of all necessary costs and expenses incident
             -----                                                             
to such foreclosure sale, including but not limited to all reasonable attorneys'
fees and legal expenses, all court costs and charges of every character, and
publication fees and costs, and to the payment of the other secured
indebtedness, including specifically without limitation the principal, accrued
interest and attorneys' fees due and unpaid on the Note and the amounts due and
unpaid and owed to Mortgagee under this Mortgage, the order and manner of
application to the items in this clause FIRST to be in Mortgagee's sole
                                        -----                          
discretion; and SECOND, the remainder, if any there shall be, shall be paid to
                ------                                                        
Mortgagor, or to Mortgagor's heirs, devisees, representatives, successors or
assigns, or such other persons (including the holder or beneficiary of any
inferior lien) as may be entitled thereto by law; provided, however, that if
Mortgagee is uncertain which person or persons are so entitled, Mortgagee may
interplead such remainder in any court of competent jurisdiction, and the amount
of any attorneys' fees, court costs and expenses incurred in such action shall
be a part of the secured indebtedness and shall be reimbursable (without
limitation) from such remainder.

          Section 5.3.  Mortgagee as Purchaser.  Mortgagee shall have the right
                        ----------------------                                 
to become the purchaser at any sale held by Mortgagee or substitute or successor
or by any receiver or at any public sale, and Mortgagee shall have the right to
credit upon the amount of Mortgagee's successful bid, to the extent necessary to
satisfy such bid, all or any part of the secured indebtedness in such manner and
order as Mortgagee may elect.
<PAGE>
 
          Section 5.4.  Remedies Cumulative.  All rights and remedies provided
                        -------------------                                   
for herein and in any other Loan Document are cumulative of each other and of
any and all other rights and remedies existing at law or in equity, and
Mortgagee shall, in addition to the rights and remedies provided herein or in
any other Loan Document, be entitled to avail itself of all such other rights
and remedies as may now or hereafter exist at law or in equity for the
collection of the secured indebtedness and the enforcement of the covenants
herein and the foreclosure of the liens and interests evidenced hereby, and the
resort to any right or remedy provided for hereunder or under any such other
Loan Document or provided for by law or in equity shall not prevent the
concurrent or subsequent employment of any other appropriate right or rights or
remedy or remedies.

          Section 5.5.  Mortgagee's Discretion as to Security.  Mortgagee may
                        -------------------------------------                
resort to any security given by this Mortgage or to any other security now
existing or hereafter given to secure the payment of the secured indebtedness,
in whole or in part, and in such portions and in such order as may seem best to
Mortgagee in its sole and uncontrolled discretion, and any such action shall not
in any way be considered as a waiver of any of the rights, benefits, liens or
interests evidenced by this Mortgage.

          Section 5.6.  Mortgagor's Waiver of Certain Rights.  To the full
                        ------------------------------------              
extent Mortgagor may do so, Mortgagor agrees that Mortgagor will not at any time
insist upon, plead, claim or take the benefit or advantage of any law now or
hereafter in force providing for any appraisement, valuation, stay, extension or
redemption, homestead, moratorium, reinstatement, marshalling or forbearance,
and Mortgagor, for Mortgagor, Mortgagor's successors and assigns, and for any
and all persons ever claiming any interest in the Property, to the extent
permitted by applicable law, hereby waives and releases all rights of
redemption, valuation, appraisement, stay of execution, reinstatement, notice of
intention to mature or declare due the whole of the secured indebtedness, notice
of election to mature or declare due the whole of the secured indebtedness and
all rights to a marshaling of assets of Mortgagor, including the Property, or to
a sale in inverse order of alienation in the event of foreclosure of the liens
and/or security interests hereby created.  Mortgagor shall not have or assert
any right under any statute or rule of law pertaining to the marshaling of
assets, sale in inverse order of alienation, the exemption of homestead, the
administration of estates of decedents, or other matters whatever to defeat,
reduce or affect the right of Mortgagee under the terms of this Mortgage to a
sale of the Property for the collection of the secured indebtedness without any
prior or different resort for collection, or the right of Mortgagee under the
terms of this Mortgage to the payment of the secured indebtedness out of the
proceeds of sale of the Property in preference to every other claimant whatever.
Mortgagor waives any right or remedy which Mortgagor may have or be able to
assert, pursuant to any provision of applicable law, pertaining to the rights
and remedies of sureties.  If any law referred to in this Section and now in
force, of which Mortgagor or Mortgagor's successors or assigns or any other
persons claiming any interest in the Property might take advantage despite this
Section, shall hereafter be repealed or cease to be in force, such law shall not
thereafter be deemed to preclude the application of this Section.  Mortgagor
acknowledges that all waivers of the aforesaid rights of Mortgagor have been
made knowingly, intentionally and willingly by Mortgagor as part of a bargained
for loan transaction and that this Mortgage is valid and enforceable by
Mortgagee against Mortgagor in accordance with all the terms and conditions
hereof.

          Section 5.7.  Delivery of Possession After Foreclosure.  In the event
                        ----------------------------------------               
there is a foreclosure sale hereunder and at the time of such sale, Mortgagor or
Mortgagor's successors or assigns are occupying or using the Property, or any
part thereof, each and all shall immediately become the tenant of the purchaser
at such sale, which tenancy shall be a tenancy from day to day, terminable at
the will of either landlord or tenant, at a reasonable rental per day based upon
the value of the property occupied, such rental to be due daily to the
purchaser; and to the extent permitted by applicable law, the purchaser at such
sale shall, notwithstanding any language herein apparently to the contrary, have
the sole option to demand immediate possession following the sale or to permit
the occupants to remain as tenants at will.  In the event the tenant fails to
surrender possession of said property upon demand, the purchaser shall be
entitled to institute and maintain a summary action for possession of the
property (such as an action for forcible detainer) in any court having
jurisdiction.

          Section 5.8.  Withdrawal, Discontinuance or Abandonment of
                        --------------------------------------------
Proceedings.  In the case Mortgagee shall have proceeded to enforce any right,
power or remedy under this Mortgage by foreclosure, entry or otherwise or in the
event that Mortgagee shall have commenced advertising the intended exercise of
the right of foreclosure provided hereunder, and such proceeding or
advertisement shall be withdrawn, discontinued or abandoned for any reason, or
shall be determined adversely to Mortgagee, then, in every such case (i)
Mortgagor and Mortgagee shall be restored to their former positions and rights,
(ii) all rights, powers and remedies of Mortgagee shall continue as if no such
proceeding had been taken, (iii) each and every default declared and remaining
uncured prior to such withdrawal, discontinuance or abandonment shall and shall
be deemed to be a continuing default, and (iv) neither this Mortgage, the Note,
the secured indebtedness nor any other instrument concerned therewith shall be
or shall be deemed to have been reinstated or otherwise affected by such
withdrawal, discontinuance or abandonment, and Mortgagor hereby expressly waives
the benefit of any statute or rule of law which would produce a result contrary
to or in conflict with the foregoing.

 
                           ARTICLE 6 - MISCELLANEOUS
                                       -------------

          Section 6.1.  Scope of Mortgage.  This Mortgage is a mortgage,
                        -----------------                               
collateral assignment, security agreement and financing statement and also
covers proceeds and fixtures.

          Section 6.2.  Effective as a Financing Statement.  This Mortgage shall
                        ----------------------------------                      
be effective as a financing statement filed as a fixture filing with respect to
all fixtures included within the Property and is to be filed for record in the
real estate records of each county where any part of the Property (including
said fixtures) is situated.  This Mortgage shall also be effective as a
financing statement covering minerals or the like (including oil and gas) and
accounts and is to be filed for record in the 
<PAGE>
 
real estate records of each county where any part of the Property is situated.
This Mortgage shall also be effective as a financing statement covering any
other Property and may be filed in any other appropriate filing or recording
office. The mailing address of Mortgagor is the address of Mortgagor set forth
at the end of this Mortgage and the address of Mortgagee from which information
concerning the security interests hereunder may be obtained is the address of
Mortgagee set forth at the end of this Mortgage. A carbon, photographic or other
reproduction of this Mortgage or of any financing statement relating to this
Mortgage shall be sufficient as a financing statement for any of the purposes
referred to in this Section.

          Section 6.3.  Notice to Account Debtors.  In addition to the rights
                        -------------------------                            
granted elsewhere in this Mortgage, Mortgagee may at any time notify the account
debtors or obligors of any accounts, chattel paper, negotiable instruments or
other evidences of indebtedness included in the Collateral to pay Mortgagee
directly.

          Section 6.4.  Waiver by Mortgagee.  Mortgagee may at any time and from
                        -------------------                                     
time to time by a specific writing intended for the purpose: (a) waive
compliance by Mortgagor with any covenant herein made by Mortgagor to the extent
and in the manner specified in such writing; (b) consent to Mortgagor's doing
any act which hereunder Mortgagor is prohibited from doing, or to Mortgagor's
failing to do any act which hereunder Mortgagor is required to do, to the extent
and in the manner specified in such writing; (c) release any part of the
Property or any interest therein from the lien and security interest of this
Mortgage; or (d) release any party liable, either directly or indirectly, for
the secured indebtedness or for any covenant herein or in any other Loan
Document, without impairing or releasing the liability of any other party.  No
such act shall in any way affect the rights or powers of Mortgagee hereunder
except to the extent specifically agreed to by Mortgagee in such writing.

          Section 6.5.  No Impairment of Security.  The lien, interest and other
                        -------------------------                               
security rights of Mortgagee hereunder or under any other Loan Document shall
not be impaired by any indulgence, moratorium or release granted by Mortgagee
including, but not limited to, any renewal, extension or modification which
Mortgagee may grant with respect to any secured indebtedness, or any surrender,
compromise, release, renewal, extension, exchange or substitution which
Mortgagee may grant in respect of the Property, or any part thereof or any
interest therein, or any release or indulgence granted to any endorser,
guarantor or surety of any secured indebtedness.  The taking of additional
security by Mortgagee shall not release or impair the lien, interest or other
security rights of Mortgagee hereunder or affect the liability of Mortgagor or
of any endorser, guarantor or surety, or improve the right of any junior
lienholder in the Property (without implying hereby Mortgagee's consent to any
junior lien).

          Section 6.6.  Acts Not Constituting Waiver by Mortgagee.  Mortgagee
                        -----------------------------------------            
may waive any default without waiving any other prior or subsequent default.
Mortgagee may remedy any default without waiving the default remedied.  Neither
failure by Mortgagee to exercise, nor delay by Mortgagee in exercising, nor
discontinuance of the exercise of any right, power or remedy (including but not
limited to the right to accelerate the maturity of the secured indebtedness or
any part thereof) upon or after any default shall be construed as a waiver of
such default or as a waiver of the right to exercise any such right, power or
remedy at a later date.  No single or partial exercise 
<PAGE>
 
by Mortgagee of any right, power or remedy hereunder shall exhaust the same or
shall preclude any other or further exercise thereof, and every such right,
power or remedy hereunder may be exercised at any time and from time to time. No
modification or waiver of any provision hereof nor consent to any departure by
Mortgagor therefrom shall in any event be effective unless the same shall be in
writing and signed by Mortgagee and then such waiver or consent shall be
effective only in the specific instance, for the purpose for which given and to
the extent therein specified. No notice to nor demand on Mortgagor in any case
shall of itself entitle Mortgagor to any other or further notice or demand in
similar or other circumstances. Remittances in payment of any part of the
secured indebtedness other than in the required amount in immediately available
U.S. funds shall not, regardless of any receipt or credit issued therefor,
constitute payment until the required amount is actually received by Mortgagee
in immediately available U.S. funds and shall be made and accepted subject to
the condition that any check or draft may be handled for collection in
accordance with the practice of the collecting bank or banks. Acceptance by
Mortgagee of any payment in an amount less than the amount then due on any
secured indebtedness shall be deemed an acceptance on account only and shall not
in any way excuse the existence of a default hereunder.

          Section 6.7.  Mortgagor's Successors.  If the ownership of the
                        ----------------------                          
Property or any part thereof becomes vested in a person other than Mortgagor,
Mortgagee may, without notice to Mortgagor, deal with such successor or
successors in interest with reference to this Mortgage and to the indebtedness
secured hereby in the same manner as with Mortgagor, without in any way
vitiating or discharging Mortgagor's liability hereunder or for the payment of
the indebtedness or performance of the obligations secured hereby.  No transfer
of the Property, no forbearance on the part of Mortgagee, and no extension of
the time for the payment of the indebtedness secured hereby given by Mortgagee
shall operate to release, discharge, modify, change or affect, in whole or in
part, the liability of Mortgagor hereunder for the payment of the indebtedness
or performance of the obligations secured hereby or the liability of any other
person hereunder for the payment of the indebtedness secured hereby.  Mortgagor
agrees that it shall be bound by any modification of this Mortgage or any of the
other Loan Documents made by Mortgagee and any subsequent owner of the Property,
with or without notice to such Mortgagor, and no such modifications shall impair
the obligations of such Mortgagor under this Mortgage or any other Loan
Document.  Nothing in this Section or elsewhere in this Mortgage shall be
construed to imply Mortgagee's consent to any transfer of the Property.

          Section 6.8.  Place of Payment; Forum.  All secured indebtedness which
                        -----------------------                                 
may be owing hereunder at any time by Mortgagor shall be payable at the place
designated in the Note or if no such designation is made, at the address of
Mortgagee indicated at the end of this Mortgage.   Mortgagor hereby irrevocably
submits generally and unconditionally for itself and in respect of its property
to the non-exclusive jurisdiction of any state or United States federal court
sitting in the county in which the secured indebtedness is payable, and to the
non-exclusive jurisdiction of any state or United States federal court sitting
in the state in which any of the Property is located, over any suit, action or
proceeding arising out of or relating to this Mortgage or the secured
indebtedness.  Mortgagor hereby agrees and consents that, in addition to any
methods of service of process provided for under applicable law, all service of
process in any such suit, action or proceeding in any state or United States
federal court sitting in the county in which the secured indebtedness is payable
may be made by certified or registered mail, return receipt requested, 
<PAGE>
 
directed to Mortgagor at its address stated in this Mortgage, or at a subsequent
address of Mortgagor of which Mortgagee received actual notice from Mortgagor in
accordance with this Mortgage, and service so made shall be complete five (5)
days after the same shall have been so mailed.

     Section 6.9.  Subrogation to Existing Liens; Vendor's Lien.  To the
                   --------------------------------------------         
extent that proceeds of the Note are used to pay indebtedness secured by any
outstanding lien, interest, charge or prior encumbrance against the Property,
such proceeds have been advanced by Mortgagee at Mortgagor's request, and
Mortgagee shall be subrogated to any and all rights, interests and liens owned
by any owner or holder of such outstanding liens, security interests, charges or
encumbrances, however remote, irrespective of whether said liens, interests,
charges or encumbrances are released, and all of the same are recognized as
valid and subsisting and are renewed and continued and merged herein to secure
the secured indebtedness, but the terms and provisions of this Mortgage shall
govern and control the manner and terms of enforcement of the liens, security
interests, charges and encumbrances to which Mortgagee is subrogated hereunder.
It is expressly understood that, in consideration of the payment of such
indebtedness by Mortgagee, Mortgagor hereby waives and releases all demands and
causes of action for offsets and payments in connection with the said
indebtedness.  If all or any portion of the proceeds of the loan evidenced by
the Note or of any other secured indebtedness has been advanced for the purpose
of paying the purchase price for all or a part of the Property, no vendor's lien
is waived; and Mortgagee shall have, and is hereby granted, a vendor's lien on
the Property as cumulative additional security for the secured indebtedness.
Mortgagee may foreclose under this Mortgage or under the vendor's lien without
waiving the other or may foreclose under both.

     Section 6.10. Application of Payments to Certain Indebtedness.  If
                   -----------------------------------------------     
any part of the secured indebtedness cannot be lawfully secured by this Mortgage
or if any part of the Property cannot be lawfully subject to the lien and
interest hereof to the full extent of such indebtedness, then all payments made
shall be applied on said indebtedness first in discharge of that portion thereof
which is not secured by this Mortgage.

     Section 6.11. Compliance with Usury Laws.  It is the intent of
                   --------------------------                      
Mortgagor and Mortgagee and all other parties to the Loan Documents to conform
to and contract in strict compliance with applicable usury law from time to time
in effect.  All agreements between Mortgagee and Mortgagor (or any other party
liable with respect to any indebtedness under the Loan Documents) are hereby
limited by the provisions of this Section which shall override and control all
such agreements, whether now existing or hereafter arising.  In no way, nor in
any event or contingency (including but not limited to prepayment, default,
demand for payment, or acceleration of the maturity of any obligation), shall
the interest taken, reserved, contracted for, charged, chargeable, or received
under this Mortgage, the Note or any other Loan Document or otherwise, exceed
the maximum nonusurious amount permitted by applicable law (the "Maximum
                                                                 -------
Amount").  If, from any possible construction of any document, interest would
- ------
otherwise be payable in excess of the Maximum Amount, any such construction
shall be subject to the provisions of this Section and such document shall ipso
                                                                           ----
facto be automatically reformed and the interest payable shall be automatically
- -----                                                                          
reduced to the Maximum Amount, without the necessity of execution of any
amendment or new document.  If Mortgagee shall ever receive anything of value
which is
<PAGE>
 
characterized as interest under applicable law and which would apart
from this provision be in excess of the Maximum Amount, an amount equal to the
amount which would have been excessive interest shall, without penalty, be
applied to the reduction of the principal amount owing on the secured
indebtedness in the inverse order of its maturity and not to the payment of
interest, or refunded to Mortgagor or the other payor thereof if and to the
extent such amount which would have been excessive exceeds such unpaid
principal.  The right to accelerate maturity of the Note or any other secured
indebtedness does not include the right to accelerate any interest which has not
otherwise accrued on the date of such acceleration, and Mortgagee does not
intend to charge or receive any unearned interest in the event of acceleration.
All interest paid or agreed to be paid to Mortgagee shall, to the extent
permitted by applicable law, be amortized, prorated, allocated and spread
throughout the full stated term (including any renewal or extension) of such
indebtedness so that the amount of interest on account of such indebtedness does
not exceed the Maximum Amount.  As used in this Section, the term "applicable
law" shall mean applicable laws of the State of Georgia or the federal laws of
the United States applicable to this transaction, whichever laws allow the
greater interest, as such laws now exist or may be changed or amended or come
into effect in the future.

     Section 6.12.  Cancellation of Mortgage.  If all of the secured
                    ------------------------                        
indebtedness be paid as the same becomes due and payable and all of the
covenants, warranties, undertakings and agreements made in this Mortgage are
kept and performed, and all obligations, if any, of Mortgagee for further
advances have been terminated, then, and in that event only, this Mortgage shall
be cancelled by Mortgagee in due form at Mortgagor's cost.  Without limitation,
all provisions herein for indemnity of Mortgagee shall survive discharge of the
secured indebtedness and any foreclosure, release or termination of this
Mortgage.

     Section 6.13.  Notices.  All notices, requests, consents, demands and
                    -------                                               
other communications required or which any party desires to give hereunder or
under any other Loan Document shall be in writing and, unless otherwise
specifically provided in such other Loan Document, shall be deemed sufficiently
given or furnished if delivered by personal delivery, by courier, or by
registered or certified United States mail, postage prepaid, addressed to the
party to whom directed at the addresses specified at the end of this Mortgage
(unless changed by similar notice in writing given by the particular party whose
address is to be changed) or by telex, or facsimile.  Any such notice or
communication shall be deemed to have been given and to be effective either at
the time of personal delivery or, in the case of courier or mail, as of the date
of first attempted delivery at the address and in the manner provided herein,
or, in the case of telex, when transmitted (answerback confirmed), or, in the
case of facsimile, upon receipt.  Notwithstanding the foregoing, no notice of
change of address shall be effective except upon receipt.  This Section shall
not be construed in any way to affect or impair any waiver of notice or demand
provided in any Loan Document or to require giving of notice or demand to or
upon any person in any situation or for any reason.  All notices given to
Mortgagee by any person or entity (other than Mortgagor) pursuant to 42 PA.
C.S.A. (S) 8143(c) or (d) shall be in writing and shall be sent exclusively by
registered or certified mail, return receipt requested, to Mortgagee at the
address set forth at the end of this Mortgage.
<PAGE>
 
     Section 6.14.  Invalidity of Certain Provisions.  A determination that
                    --------------------------------                       
any provision of this Mortgage is unenforceable or invalid shall not affect the
enforceability or validity of any other provision and the determination that the
application of any provision of this Mortgage to any person or circumstance is
illegal or unenforceable shall not affect the enforceability or validity of such
provision as it may apply to other persons or circumstances.

     Section 6.15.  Gender; Titles; Construction.  Within this Mortgage,
                    ----------------------------                        
words of any gender shall be held and construed to include any other gender, and
words in the singular number shall be held and construed to include the plural,
unless the context otherwise requires.  Titles appearing at the beginning of any
subdivisions hereof are for convenience only, do not constitute any part of such

                     ------------------------------------

hereunder are strictly limited to those set forth in paragraphs B and E hereof
and in Sections 1.5, 2.1, 2.2, 2.3, 2.4, 2.5, 2.6, 2.7, 2.8, 2.9, 2.10, 5.3,
7.3(a), 7.3(b), 7.3(d), 7.3(f), 19.4, 19.5, 19.10, 19.11, 19.12, 19.13, 19.14,

liable under this Lease, directly or indirectly, except as and to the extent
specifically set forth in the foregoing enumerated Sections hereof (although
Contractor shall be entitled to all of its rights as set forth under such
Sections and elsewhere in this Lease), provided that nothing herein shall be
construed as limiting the Tenant from bringing an action or pursuing a remedy
under this Lease, at law or in equity, against the Landlord regardless of
whether (i) Tenant has a direct right under the Lease to pursue an action
against the Contractor or (ii) the Landlord is deemed to have waived its rights
against the Contractor under the terms of the foregoing provisions.

                                   Recitals
                                   --------

     A.   Tenant desires to lease from Landlord that certain parcel of vacant
land comprised of approximately 10.5 acres, located in Susquehanna Township,
Dauphin County, Pennsylvania ("Township"), which parcel is legally described in
Exhibit A-1 attached hereto and made a part hereof ("Land"), together with those
certain improvements to be constructed thereon in accordance with this Lease.
The Land is situated in that certain business park located in the Township and
known as Commerce Park ("Park"). Title to the Land is, and shall be, subject to
the encumbrances and other matters set forth in Exhibit A-2 attached hereto and
made a part hereof ("Permitted Encumbrances").

     B.   The parties have agreed that Landlord shall cause Contractor to
construct, and that Contractor shall construct, initial improvements on the Land
consisting of a four (4)-story office facility to be comprised of approximately
81,859 square feet ("Initial Improvements"). The parties have also agreed that
Tenant will have the option, pursuant to this Lease, to cause Landlord to
construct (or to cause to be constructed) the Expansion Improvements (as such
term is defined in Section 2A.1(a) hereof). The Initial Improvements and the
Expansion Improvements (if any), together, are hereinafter collectively referred
to as "Landlord's Improvements." Construction of the Initial Improvements, and
Landlord's and Contractor's respective obligations with respect thereto, shall
be as set forth in this Lease. Construction of the Expansion Improvements, and
Landlord's obligations with respect thereto (Contractor having no obligations
with respect to the Expansion Improvements), shall also be as set forth in this
Lease. Further, the parties have agreed that Tenant shall have certain rights to
renew the term of this Lease, as also set forth herein.

     C.   Landlord, for and in consideration of the rents, covenants and
agreements hereinafter contained, hereby leases, rents, lets and demises unto
Tenant, and Tenant does hereby take and hire, upon and subject to the conditions
and limitations hereinafter expressed, the Land, together with all improvements
located thereon and to be constructed thereon from time to time pursuant to the
terms, provisions and conditions hereof (including, without limitation,
Landlord's Improvements), subject to the Permitted Encumbrances.

     D.   Landlord's Improvements and all other improvements, machinery,
equipment, fixtures and other property, real, personal or mixed, from time to
time installed or located on the Land (except those items of Tenant's attached
or unattached personalty which are deemed to be trade fixtures, as described in
Article 16 hereof ("Trade Fixtures")), together with all additions, alterations
and replacements thereof, are hereinafter collectively referred to as
"Improvements." The Land and the Improvements are hereinafter collectively
referred to as "Demised Premises." The initial interior improvements to be
constructed in the Initial Improvements, as described further in Section 2.1
hereof, are hereinafter referred to as "Initial Interior Build-Out." Anything in
this Lease to the contrary notwithstanding, (i) "Landlord's Improvements" and,
therefore, "Improvements" and "Demised Premises," shall include, without
limitation, the "Initial Improvements" and the "Expansion Improvements," if any,
and (ii) the "Initial Improvements" shall include, without limitation, the
"Initial Interior Build-Out."

     E.   Tenant acknowledges that Landlord has contracted to purchase, but as
of the date of this Lease, does not own fee title to the Land.  Accordingly,
anything in this Lease to the contrary notwithstanding, in the event that
Landlord does not acquire fee title to the Land, or in the event that Landlord's
acquisition of fee title to the Land is delayed, and (i) such failure or delay
is not a direct result of any breach by Landlord of its contract to purchase the
Land, and (ii) Landlord is diligent in pursuing its rights and remedies under
the terms of said contract, then neither Landlord nor Contractor shall be liable
for any damages or other remedies as a result of any failure or delay in their
respective obligations to Tenant under this Lease.


                                   ARTICLE 1
                                 TERM OF LEASE

     SECTION 1.1 INITIAL TERM. Except as otherwise provided in this Lease, the
term of this Lease ("Initial Term") shall be for ten (10) years (subject to
renewal thereof as described in Section 1.3 hereof), commencing on the Initial
Term Commencement Date (as such term is defined in Section 1.2 hereof), and
ending on the date which is ten (10) years, less one (1) day, after the Initial
Term Commencement Date ("Initial Term Termination Date"). As of the date of this
Lease, Landlord and Tenant anticipate that the Initial Term Commencement Date
will be September 1, 1998, and that the Initial Term Termination Date will
therefore be August 31, 2008; provided, however, that nothing in this Lease
shall prevent the Initial Term Commencement Date from occurring prior to
September 1, 1998 (and the Initial Term Termination Date thereby occurring
earlier than August 31, 2008), but the Delivery Date (as described in Section
1.2) shall not be earlier than July 1, 1998. The Initial Term Commencement Date
and the Initial Term Termination Date are subject to adjustment as set forth in
this Article 1 and in Section 2.5 hereof, but in no instance shall the Initial
Term be less than ten (10) years, unless sooner terminated as provided herein.
The

                                       2

Initial Term shall commence ("Initial Term Commencement Date") on the Delivery
Date.

     SECTION 1.2 DELIVERY DATE; INITIAL TERM COMMENCEMENT DATE. The "Delivery
Date" shall be the date on which all of the foregoing have occurred: (i) the
Landlord's Improvements have been Substantially Completed (as defined in Section
2.5(d)); (ii) a Certificate of Use for the Demised Premises has been obtained
from the Commonwealth of Pennsylvania Labor and Industry; (iii) a Certificate of
Occupancy for the Demised Premises has been obtained from the Township; (iv) the
Landlord and Tenant have (and to the extent they do not agree, the Architect, as
such term is defined in Section 2.1 hereof, has) established the Punch List
Items (as defined and provided in Section 2.8); and (v) Landlord has provided
Tenant with a Subordination, Non-Disturbance and Attornment Agreement, in the
form attached hereto as Exhibit 1.2, executed by each mortgagee or other
lienholder included in the Permitted Encumbrances. However, anything in this
Lease (including, without limitation, anything in this Section 1.2 or in Section
2.5 hereof) to the contrary notwithstanding, in the event that (a) Initial
Improvements have not been Substantially Completed, and (b) the Architect has
certified that, as of a date certain set forth in such certification, the
Initial Improvements would have been Substantially Completed, but for a Tenant
Extension (as such term is defined in Section 2.5(b)(i) hereof), then the
Initial Term Commencement Date shall nonetheless be deemed to have occurred on
the date certain set forth in the Architect's aforesaid certification.
Regardless of any other provision herein, the Delivery Date shall not be earlier
than July 1, 1998.

     SECTION 1.3 OPTIONS TO RENEW. Subject to the terms, provisions and
conditions of this Lease, Tenant shall have four options to renew the term of
this Lease beyond the end of the Initial Term, the first three such renewal
options being for one five (5)-year period and the fourth renewal option being
for one four (4) year, eleven (11) month period, each, running consecutively
from the end of the prior period. In the event that Tenant exercises any or all
of such options to renew, and except as provided in Section 2A.1(g) hereof, the
time period from the day after the last day of the Initial Term through the date
which is five (5) years, less one (1) day, thereafter, is hereinafter referred
to as the "First Renewal Term," the time period from the day after the First
Renewal Term through the date which is five (5) years, less one (1) day,
thereafter, is hereinafter referred to as the "Second Renewal Term," the time
period from the Second Renewal Term through the date which is five (5) years,
less one (1) day, thereafter, is hereinafter referred to as the "Third Renewal
Term," and the period from the day after the Third Renewal Term through the date
which is four (4) years and eleven (11) months thereafter, is hereinafter
referred to as the "Fourth Renewal Term." The First Renewal Term, the Second
Renewal Term, the Third Renewal Term and the Fourth Renewal Term are sometimes
hereinafter individually referred to as a "Renewal Term," and are sometimes
hereinafter collectively referred to as "Renewal Terms." The Initial Term and
any and all Renewal Terms are sometimes hereinafter collectively referred to as
the "Term."

     Except for modifications of Base Rent (as such term is defined in Section
3.1(a) hereof) pursuant to Section 3.1 hereof, and except as otherwise
specifically provided herein, the terms, provisions and conditions of this Lease
shall apply during each Renewal Term exercised by Tenant as hereafter provided
as and to the same extent as they apply during the Initial Term.

     SECTION 1.4 EXERCISE OF OPTIONS TO RENEW. Subject to Section 3.1(c) hereof,
if Tenant wishes to exercise its options for any of the Renewal Terms, it shall
give written notice thereof ("Renewal Notice") to Landlord not later than twelve
(12) months prior to the expiration of the Initial Term or the Renewal Term then
in effect, as applicable, provided, however, that if Tenant

                                       3
<PAGE>
 
shall fail to give any such notice within the aforesaid time limit, Tenant's
right to exercise its renewal option shall nevertheless continue until ("Renewal
Cut-Off") the first to occur of (i) thirty (30) days after Landlord shall have
given Tenant notice of Landlord's election to terminate such option, and (ii)
one hundred and twenty (120) days prior to the expiration of that portion of the
Term then in effect, and Tenant may exercise such option at any time until the
Renewal Cut-Off. It shall be a condition to the exercise and effectiveness of
each option for a Renewal Term that Tenant shall not be in Default (as such term
is defined in Section 10.1 hereof) of any of the terms, provisions or conditions
of this Lease, either at the time of delivery of the Renewal Notice in question,
or at the commencement of the Renewal Term in question; provided, however, that
Landlord shall have the right, in its sole discretion, to waive any such Default
for purposes of Tenant's exercise of the subject Renewal Term. Notwithstanding
the foregoing, Tenant shall not be permitted to exercise its right to the Second
Renewal Term and to each succeeding Renewal Term unless Tenant has exercised its
right to the First Renewal Term and the Renewal Term preceding the one Tenant is
then electing to exercise.

     Anything in this Lease to the contrary notwithstanding, in the event Tenant
exercises its Expansion Option (as such term is defined in Section 2A.1(a)
hereof), then Tenant shall automatically and conclusively be deemed to have
exercised an option to renew as provided in Section 2A.1(g), provided that
Tenant shall have the right to withdraw its exercise of the Renewal Term, as
provided in Section 2A.1(g) in the event that the Landlord defaults in its
obligations under Section 2A.1 to construct the Expansion Improvements.

     SECTION 1.5 LAND ACQUISITION CONTINGENCY. Landlord and Tenant acknowledge
and agree that Landlord has entered into that certain purchase and sale
agreement ("Real Estate Agreement"), pursuant to which Landlord has contracted
to acquire fee title to the Land from the current owner thereof, but the closing
of the purchase and sale thereunder as of the date hereof has not yet occurred.
Landlord shall diligently (i) proceed to close on the Real Estate Agreement, and
(ii) submit applications for subdivision approval, land development plan
approval, sewer and water permits, highway occupancy permits, a building permit
and all other governmental permits and approvals (the "Permits and Approvals")
required for the construction of the Demised Premises, and shall thereafter
diligently pursue receipt of such Permits and Approvals in final, nonappealable
form. In the event, (a) on or before December 31, 1997 ("Real Estate Date"),
Landlord fails to acquire fee title to the Land in accordance with the
provisions of the Real Estate Agreement as a result of a default of the seller
thereunder, or (b) on or before December 31, 1997 ("Permit Date") Landlord fails
to receive, after extending diligent efforts in respect thereto, the Permits and
Approvals (in final, nonappealable form) necessary to commence construction of
the Demised Premises, then, in either instance, Landlord shall advise Tenant of
the same, in writing, delivered by overnight delivery service within three (3)
business days thereafter. If Landlord has acquired title to the Real Estate
pursuant to the terms of the Real Estate Agreement prior to Real Estate Date,
but has not then acquired the all of the necessary Permits and Approvals prior
to the Permit Date, the Permit Date shall be deemed extended to January 31,
1998, and such extension shall be deemed a Permitted Delay. If fee title to the
Real Estate has not been acquired as aforesaid prior to the Real Estate Date or
the Permits and Approvals have not been received as aforesaid prior to the
Permit Date (extended, if at all, as aforesaid), then either Landlord or Tenant
shall have the right to terminate this Lease within thirty (30) days following
the receipt of Landlord's notice as aforesaid. Notwithstanding the foregoing, if
either the Real Estate Date or the Permit Date (extended, if at all, as
aforesaid) have lapsed without Landlord, respectively, acquiring fee title to
the Real Estate or

                                       4
<PAGE>
 
receiving the Permits and Approvals, each as aforesaid, solely because of the
failure of the Landlord to diligently pursue fulfillment thereof, then the
Landlord shall pay to the Tenant the amount of Five Hundred Thousand Dollars
($500,000.00), as liquidated damages incurred by Tenant resulting from such
failure of the Landlord, if either Landlord or Tenant Terminate this Lease as
above provided. The parties hereto have fully negotiated the provisions of this
Section 1.5 with respect to liquidated damages, as well as the balance of the
terms, provisions and conditions of this Lease, free from any duress or other
undue influence. Having determined that the actual amount of any losses which
Tenant would incur as a result of the unwillingness of the Landlord to extend
diligent efforts to close on the Real Estate Agreement and obtain the Permits
and Approvals prior to, respectively, the Real Estate Date and Permit Date
(extended, if at all, as aforesaid) would be difficult, if not impossible to
ascertain, the parties have, independently and in good faith, determined that
the foregoing liquidated damages are a fair and reasonable estimation of and
basis for any losses. The foregoing liquidated damages shall be in lieu of (and
not in addition to) any other rights or remedies which Tenant would otherwise
have at law or in equity.


                                   ARTICLE 2
                    CONSTRUCTION OF LANDLORD'S IMPROVEMENTS

     SECTION 2.1 PRELIMINARY PLANS - CERTAIN REIMBURSEMENTS. As set forth in
paragraph B of the Recitals, the Initial Improvements shall consist of a four
(4)-story office facility to be comprised of approximately 81,859 square feet.
Attached hereto and made a part hereof as Exhibit 2.1 is a list describing or
identifying certain plans and specifications comprised of (i) final civil
engineering plans (that, as a component of the Final Plans, as hereafter
defined, have been approved by Landlord, Tenant and Contractor, which component
is hereafter referred to as "Land Development Plans"), (ii) preliminary base
building plans for the Initial Improvements, including structural engineering
plans, building elevations, interior and exterior architectural plans, and
specifications, and (iii) outline performance specifications with respect to the
Initial Improvements, including specifications for the civil, architectural,
structural, electrical systems, plumbing systems, heating, ventilating and air
conditioning systems, fire protection systems, and landscaping in and around the
Initial Improvements (collectively, in respect to clauses (ii) and (iii),
"Preliminary Plans and Specifications"). The Preliminary Plans and
Specifications are in detail satisfactory (given the fact that they are only
preliminary) to Landlord, Contractor and Tenant, and depict the Initial
Improvements which Landlord will cause Contractor to construct, and which
Contractor will construct, on the Land for the benefit of Tenant, subject to
finalization and preparation of the Final Plans and all in accordance with this
Article 2.

     Landlord shall cause all of the remaining components of the Final Plans to
be prepared by VOA Associates, Inc. of Washington, DC (the "Architect"), R. J.
Fisher & Associates, Inc. and/or Environmental Systems Design, Inc., as
applicable (collectively, "Design Team"). Each of the Components of the Final
Plans shall be delivered to Tenant for approval, in accordance with Section 2.2
hereof.

     Within ten (10) days of the date of this Lease, Landlord shall reimburse
Tenant for (i) Twenty-Three Thousand One Hundred Forty-Two and 23/100 Dollars
($23,142.23) previously paid by Tenant to the Architect, and (ii) Fifteen
Thousand and No/100 Dollars ($15,000.00) previously paid by Tenant to Tenant's
Broker (as defined in Section 19.19). Within thirty (30) days after the

                                       5
<PAGE>
 
Initial Term Commencement Date, Landlord shall pay to Tenant the amount of
$84,000.00 as a reimbursement of Tenant's moving and related expenses.

     SECTION 2.2  APPROVAL OF FINAL PLANS AND SPECIFICATIONS.

     (a)  Land Development and Preliminary Plans Approval.  As of the date
          -----------------------------------------------                 
hereof, Tenant has reviewed and approved the Land Development Plans and all of
the Preliminary Plans and Specifications.


     (b)  Delivery of Final Plans and Expansion Improvements (if any); Approval
          ---------------------------------------------------------------------
of Components.  Landlord shall deliver to Tenant each of the remaining
- -------------                                                         
components of the Final Plans as soon as practicable after they have been
prepared, but in any event in that sequence set forth on the Schedule of Final
Plan Components attached hereto and made a part hereof as Exhibit 2.2(b). All of
the remaining components of the Final Plans consisting of plans and
specifications for architectural, structural engineering, landscaping, plumbing,
fire protection, heating, ventilating and air conditioning, and electrical shall
initially be delivered to Tenant for its approval or disapproval on or before
November 28, 1997. Those components of the Finals Plans described in the
preceding sentence are hereafter referred to as "Building Components."

     Landlord shall cause the Design Team, as applicable, to deliver to Tenant,
the balance of the Final Plans as soon as practicable after they have been
prepared, but in any event not later than sixty (60) days following the approval
by Tenant of all of the components comprising the Building Components.

     Landlord shall cause the Design Team to prepare all of the components of
the Final Plans in compliance with the provisions of Section 2.1 hereof and also
in accordance with (i) any and all laws, codes, ordinances, requirements,
standards, plats, plans, criteria, orders, directives, rules and regulations of
any and all applicable governmental authorities affecting the improvement,
alteration, use, maintenance, operation, occupancy, security, health, safety and
environmental condition of the Demised Premises, or any portion thereof,
including, without limitation, the Americans With Disabilities Act of 1990, as
amended from time to time, and any and all rules and regulations promulgated
pursuant thereto ("ADA"), except as provided in Section 2.3 hereof, (ii) any and
all covenants, restrictions, conditions, easements and other agreements of
record with respect to the Demised Premises, or any portion thereof, including,
without limitation, Park covenants, and any and all rules, regulations,
standards or criteria set forth or referenced therein or promulgated by the Park
association or any other governing body or entity exercising jurisdiction over
the Park, and (iii) all permits, licenses, certificates, authorizations and
approvals required in connection with any of the foregoing. All of the Final
Plans shall be consistent with the Preliminary Plans and Specifications, and
shall be reasonably satisfactory to Landlord. Notwithstanding the foregoing, in
the event there is a change in any law, code, ordinance, requirement, standard,
plat, plan, criteria, order, directive, rule or regulation of any or all
applicable governmental authority having jurisdiction over the Initial
Improvements that is passed, enacted or otherwise enforced for the first time
subsequent to the date of this Lease that requires a modification to either the
Final Plans or a substantial deviation from the Preliminary Plans and
Specifications (if the Final Plans are not yet approved), the reasonable cost
thereof shall be deemed a Change Order Cost (as hereafter defined), the time to
effectuate such change shall be a Permitted Delay and Landlord and Tenant shall
execute Change Order in respect thereto.

                                       6
<PAGE>
 
     Within five (5) business days after Landlord's initial delivery to Tenant
of each component of the Final Plans, Tenant shall either approve or disapprove
each such component, provided that Landlord has provided such component, in the
sequence provided in the Schedule of Final Plan Components attached hereto as
Exhibit 2.2(b). If at any time Tenant disapproves a component, it shall notify
Landlord thereof in writing, detailing with reasonable specificity that portion
or element of the component disapproved and the reasons for such disapproval.
Tenant shall not withhold its approval of any submitted component, unless such
submitted component fails to comply substantially with the Preliminary Plans and
Specifications. Further, Tenant shall not act in an arbitrary or capricious
fashion with respect to any disapproval of such components.

     Upon Tenant's disapproval, if any, of a component, Landlord shall undertake
to have such disapproved component modified and shall resubmit the same to
Tenant. In each instance of disapproved components, Landlord shall have five (5)
business days to revise and resubmit each such component to Tenant. In each
instance of resubmitted components, Tenant shall have three (3) business days
within which to approve or disapprove (as aforesaid) each such resubmittal. Such
respective five (5)- and three (3)- business day sequences of resubmission and
approval or disapproval shall continue until all of the components comprising
the Final Plans (or of the Final Expansion Plans, as such term is defined below
in this Section 2.2(b), if applicable) have been approved by both Landlord and
Tenant. In the event that Tenant fails to approve or disapprove any component of
the Final Plans (or of the Final Expansion Plans, if applicable) within the
applicable time period set forth herein, then such failure shall constitute a
Tenant Extension hereunder.

     When each component of the Final Plans has been approved in accordance with
this Section 2.2(b) Landlord and Tenant shall affix their respective signatures
or initials to a schedule or summary setting forth a description of such
component. Such approved components shall constitute all or a portion of the
"Final Plans" and shall be deemed to become a part of this Lease, as identified
on Exhibit 2.2(b)-1.

     With respect to the Expansion Improvements (if any), Landlord shall cause
the Expansion Architect (as defined in Section 2A.2 hereof) to prepare
components of the base building and interior plans therefor ("Final Expansion
Plans"), and shall submit them to Tenant for its approval or disapproval, in
accordance with Section 2A.2 hereof and this (b). The Final Expansion Plans
shall be consistent with the Expansion Notice (as such term is defined in
Section 2A.1(b) hereof), and shall be reasonably satisfactory to Landlord.

     Any revision to a submitted component of the Final Plans, which revision is
required to obtain Tenant's approval of the submitted component, and which, in
the Architect's reasonable opinion, would be a substantial deviation from the
Preliminary Plans and Specifications with respect to the Initial Improvements
(or the Expansion Notice with respect to the Expansion Improvements, if
applicable), shall be deemed to be a request by Tenant for a Change Order (as
such term is defined in Section 2.4 hereof). Landlord shall notify Tenant, in
writing, of any such determination by the Architect, and in such written
notification shall inform Tenant of Landlord's estimate of the change in
schedule, if any, in the completion of construction of the Initial Improvements
(or the Expansion Improvements, if applicable), and of any extra cost (or
savings) to Tenant resulting from the requested revision. Then, within ten (10)
business days after such notification, and if Tenant has not theretofore
withdrawn, in writing, its requested revision, a Change Order (as provided in
Section

                                       7
<PAGE>
 
2.4 hereof) shall automatically and conclusively be deemed to have been
approved. Provided, however, Landlord shall not be required to curtail any of
the construction of the Initial Improvements (or, as applicable, Expansion
Improvements) during the pendancy of Tenant's right to withdraw its requested
revisions, if such curtailment would have an adverse impact on the critical path
schedule for the Substantial Completion of the Initial Improvements.

     SECTION 2.3 SCOPE OF WORK. Commencing promptly after the execution and
delivery of this Lease by all of the parties hereto, and continuing thereafter
following Landlord's and Tenant's approval of the remaining components of the
Final Plans, Landlord shall cause Contractor to furnish, and Contractor shall
furnish, at Landlord's sole cost and expense, all of the material, labor and
equipment as may be necessary for the commencement and completion of
construction of the Initial Improvements, as specified in the Land Development
Plans and, when approved as aforesaid, the remaining components of the Final
Plans. The Initial Improvements shall be constructed in a good and workmanlike
manner substantially in accordance with the Final Plans. In addition, Landlord
shall cause Contractor to complete, and Contractor shall complete all such
construction in substantial compliance with all applicable laws in effect as of
the date of this Lease. In the event that any materials specified in the Final
Plans are not reasonably available to Contractor, Landlord and Contractor
reserve the right to substitute materials of higher or equal quality.

     Because compliance with ADA requirements is predicated, in part, on
specific user requirements, Landlord, Contractor and Tenant acknowledge and
agree that all three of them bear certain responsibility, as described in this
Section 2.3, for assuring that the Final Plans are in compliance with the ADA.
As an integral part of Tenant's review of the Land Development Plans and the
Preliminary Plans and Specifications, and also during the review, submittal and
revision procedure set forth herein with respect to the remaining components of
the Final Plans, Tenant has informed Landlord and Contractor, and shall inform
Landlord and Contractor of Tenant's intended use of the Demised Premises. Among
other things, the preparation of the Land Development Plans, Preliminary Plans
and Specifications and the remaining components of the Final Plans by Design
Team is and will be based on the ADA requirements for the specific use of the
Demised Premises which Tenant shall make and of which Tenant advises Landlord
and Contractor, in writing. As a result of the foregoing, to the extent Tenant
changes the specific use of the Demised Premises from that which, in writing, it
advises Landlord and Contractor, Tenant shall be responsible for the Demised
Premises (to the extent, but only to the extent, required as a result of or in
connection with Tenant's changed use of the Demised Premises) being in
compliance with the ADA.

     SECTION 2.4 CHANGES IN WORK. Although the same may constitute Tenant
Extensions hereunder, subject to this Section 2.4, Tenant, without invalidating
this Lease, may order changes in the work (or may be deemed to have ordered
changes in the work) consisting of additions to or deletions from, or other
revisions in, the Final Plans or a material deviation from the Preliminary Plans
and Specifications, if the Final Plans are not yet fully approved (or the Final
Expansion Plans, as such term is defined in Section 2A.2 hereof) with an
appropriate adjustment, if any, to the Delivery Date (or the Expansion Delivery
Date, as such term is defined in Section 2A.3 hereof), if applicable, or the
time for the preparation of components of the Final Plans (or the Final
Expansion Plans, if applicable), and with appropriate provisions for increases
or decreases in the Base Rent or the establishment of a payment obligation by
Tenant as herein provided. Such changes in the work consisting of the foregoing
addition or deletions or other revisions shall hereafter be referred to a

                                       8
<PAGE>
 
"Scope Change" or "Scope Changes." Any changes in work shall be authorized by a
written change order ("Change Order") which shall be executed as hereinafter
provided. Notwithstanding the foregoing, for the Initial Improvements only,
those Scope Changes requested by Tenant as aforesaid that have a Change Order
Cost (as hereafter defined) (i) not in excess of Five Thousand Dollars
($5,000.00) for any single Change Order, or (ii) not in excess of Ten Thousand
Dollars ($10,000.00) in the aggregate for all Change Orders shall be performed
by Landlord and Contractor at no additional charge or expense to Tenant.

     A Change Order is a written order signed by Tenant (by an authorized
individual as provided in Section 19.5) and accepted in writing by Landlord or
Contractor (if applicable), stating in detail, among other things (as
appropriate) the change in the work, any adjustment in the Delivery Date (or the
Expansion Delivery Date, if applicable), or the time for the preparation of
components of the Final Plans (or the Final Expansion Plans, if applicable),
and, if appropriate, the additional payment obligation of the Tenant or the
increase or decrease in the Base Rent as a result thereof.

     If a Change Order in respect to the Initial Improvements results in a
credit to Tenant, meaning that the Change Order Cost (as such term is defined
below in this Section 2.4) is less than the original charge for the work being
changed, the annual Base Rent for the Initial Term shall be decreased by an
amount calculated as follows: Change Order Cost multiplied by ten and 50/100ths
percent (10.50%). If a Change Order in respect to the Expansion Improvements
results in a Change Order Cost of less than the original charge for the work
being changed, Landlord shall pay to Tenant, within thirty (30) days following
the Expansion Commencement Date, the amount by which the Change Order Cost is
less than the original charge for the work being changed.

     If a Change Order in respect to the Initial Improvements results in an
additional charge to Tenant greater than the original charge for the work being
changed, then for the first Seventy-Five Thousand and No/100 Dollars
($75,000.00) (except as provided in the first grammatical paragraph of this
Section 2.4) of the Change Order Costs (except as hereafter provided in respect
to compliance with ADA), in the aggregate, of all such additional Change Orders,
the annual Base Rent for the Initial Term shall be increased by an amount
calculated as follows: the applicable Change Order Cost multiplied by one
hundred seven percent (107%) which product shall be further multiplied by ten
and 50/100ths percent (10.50%). Such increase in the annual Base Rent is
hereafter referred to as "Change Order Base Rent." Notwithstanding the
foregoing, commencing in the second year of the Initial Term and for each year
thereafter in the Initial Term, the Change Order Base Rent shall be increased by
an amount equal to two percent (2%) of the preceding year's Change Order Base
Rent. Prior to the Delivery Date, Landlord and Tenant shall each execute a
written statement setting forth the amount, if any of Change Order Base Rent.

     For Change Order Costs pertaining to compliance with ADA prior to the
Initial Term Commencement Date, the fee of seven percent (7%) of the Change
Order Costs in respect such compliance shall not be applicable or charged to
Tenant.

     For all Change Order Costs (i) in respect to the Initial Improvements that
are additional charges to Tenant as aforesaid that are, in the aggregate, in
excess of Seventy-Five Thousand and No/100 Dollars ($75,000.00) (except as
provided in the first grammatical paragraph of this Section 2.4), and (ii) in
respect to the Expansion Improvements that are additional charges to Tenant as
aforesaid, Tenant, in the instance of clause (i) and (ii) above, shall pay to
Contractor such excess 

                                       9
<PAGE>
 
Change Order Cost, plus a fee equal to seven percent (7%) of such excess Change
                   ----
Order Costs (except for Change Order Costs pertaining to compliance with ADA in
respect to the Initial Improvements as provided above), within thirty (30) days
following the date Contractor invoices Tenant for the same, provided the work in
respect to such invoiced Change Order Costs has been satisfactorily completed in
respect to the amount invoiced. In the event of a dispute as to whether the
invoiced portion of the subject excess Change Order Costs have been
satisfactorily completed, the determination of the Architect, in the instance of
the Initial Improvements, and the Expansion Architect, in the instance of the
Expansion Improvements, in respect to such dispute shall be binding on Landlord,
Tenant and Contractor, as applicable.

     A "Change Order Cost" shall be equal to the total increase or decrease in
costs resulting from the subject change (including, without limitation, any and
all design, permitting and other so-called "soft costs").  The actual costs of
the subject change shall be the aggregate of all payment obligations under those
contracts or modifications to contracts entered into by Landlord or Contractor
(if applicable), or their respective subcontractors, plus applicable general
conditions, which are necessary to effectuate the specific Change Order.

     Anything in this Lease to the contrary notwithstanding, no Change Orders
which increase the scope of any work hereunder with respect to any of Landlord's
Improvements (i.e., either the Initial Improvements or the Expansion
Improvements) shall be effective, unless Landlord gives its prior written
consent thereto.  Such consent may be given or withheld in Landlord's sole and
absolute discretion.

     SECTION 2.5  COMPLETION OF IMPROVEMENTS.

     (a)  Completion Dates.  It is anticipated that, subject to Permitted Delays
          ----------------                                                      
(as such term is defined in Section 2.5(b) hereof), the Initial Improvements
shall be Substantially Completed not later than September 1, 1998.

     (b)  Permitted Delays.  The date for the Substantial Completion of any of
          ----------------                                                    
Landlord's Improvements, the Initial Term Commencement Date, the Expansion
Commencement Date, and any and all other intermediate target dates set forth in
this Lease, shall be extended if Landlord or Contractor, or any of their
respective employees, agents, contractors (including the Design Team),
subcontractors, sub-subcontractors or representatives, is delayed as a result of
any one or more of the following:

     (i)  any act, omission or neglect of Tenant, or of any employee, agent,
          contractor, subcontractor, sub-subcontractor, agent or representative
          of Tenant, including, without limitation, the failure to approve or
          disapprove components of the Final Plans (or the Final Expansion
          Plans, if applicable) in accordance with this Lease; the requesting or
          negotiating of Change Orders; or the failure to timely complete the
          Tenant Work ("Tenant Extension");

     (ii) subject to Section 1.5 hereof, any failure or delay in Landlord's
          acquisition of fee title to the Land, which failure is not a direct
          result of

                                       10
<PAGE>
 
           any breach by Landlord of the Real Estate Agreement;

     (iii) any failure of or delay in the availability of any one or more public
           utilities on the Land for the use of Landlord, Contractor or their
           respective employees, agents, contractors, subcontractors, sub-
           subcontractors or representatives subsequent to the commencement of
           construction of the Demised Premises, other than due to the
           negligence of the Landlord, Contractor or their respective employees,
           agents, contractors, subcontractors or representatives;
 
     (iv)  any national strikes, labor disputes; or any delays or shortages
           encountered in transportation, fuel, material or supplies that in the
           instance of such delays or shortages are commercially unreasonable;

     (v)   any governmental embargo restrictions, or actions or inactions of
           local, state or federal governments (including, without limitation,
           any extraordinary delays in issuing building permits, certificates of
           occupancy or other similar permits or certificates); or

     (vi)  any casualties, acts of God or the public enemy, or other acts or
           occurrences beyond the reasonable control of Landlord or Contractor,
           or their respective employees, agents, contractors, subcontractors,
           sub-subcontractors or representatives, provided, any delays due to
           inclement weather are not within the foregoing matters, unless such
           weather conditions are in the form of extraordinary events such as
           hurricanes, tornadoes or record breaking snowfalls in respect to
           frequency or accumulation.

The Landlord and Contractor shall use their diligent efforts to prevent or
minimize any delays resulting from any one or more of the matters described in
clauses (i) through (vi), above.  Any delays resulting from any one or more of
the matters described in clauses (i) through (vi) above, except as may be due to
the negligence of the Landlord or the Contractor, or their respective employees,
agents, contractors, subcontractors, or representatives, are hereinafter
individually referred to as a "Permitted Delay," and are hereinafter
collectively referred to as "Permitted Delays."

     (c)   Effect of Permitted Delays.  Promptly following Landlord's becoming
           --------------------------                                         
aware that an occurrence will result in a Permitted Delay hereunder, Landlord
shall notify Tenant, in writing, of such occurrence and of Landlord's estimate
of the effect, if any, such occurrence will have on the time within which the
subject Landlord's Improvements shall be Substantially Complete, or on such
other target dates set forth herein (and, as noted below, in the case of a
Tenant Extension, the additional cost as a result thereof, if any, which will be
borne by Tenant), and shall provide Tenant with reasonable evidence as to the
Permitted Delay. If Landlord, Contractor and Tenant are able to agree on the
effect of any delays which result from a Permitted Delay or the cost to Tenant,
if any, in the instance of a Tenant Extension, such agreement shall be the
subject of a Change Order. If Landlord, Contractor and Tenant are unable to
agree on the effect of any delays which result from a Permitted Delay or the
cost to Tenant, if any, in the instance of a Tenant Extension (but excluding, in
the instance of cost, a Scope Change), the matter in respect to duration of the
delay or such cost shall be subject to resolution by binding arbitration of the
Arbitrator as provided in Section 2.11

                                       11
<PAGE>
 
hereof, which resolution shall likewise be the subject of a Change Order.
Landlord and Tenant are hereby required to execute a Change Order as shall agree
as aforesaid, or, absent such agreement, as determined by the Arbitrator
pursuant to Section 2.11 hereof. In the case of continuing Permitted Delays,
only one such notice from Landlord shall be necessary.

     (d)  Substantial Completion.  The Initial Improvements (and the Expansion
          ----------------------                                              
Improvements, if applicable) shall, for purposes of this Lease, be deemed to be
"Substantially Complete" (or "Substantially Completed" or "Substantial
Completion") on the date on which (i) the Architect (or the Expansion Architect,
as applicable) certifies to the Tenant that the Initial Improvements (or
Expansion Improvements, if applicable) in question have been completed in
substantial conformity with the Final Plans (or the Final Expansion Plans, if
applicable), subject to landscaping and other Punch List Items (as such term is
defined in Section 2.8 hereof); and (ii) the Township (or other governmental
authority having jurisdiction) has issued with respect thereto a certificate of
occupancy (or other consent to or approval of Tenant's use and occupancy
thereof). In the event of any disagreement between Landlord and Tenant as to
whether Substantial Completion has been achieved under clause (i) above, the
decision of the Architect (or Expansion Architect, if applicable) shall be final
and binding on the parties.

     SECTION 2.6 TENANT'S REMEDIES FOR LANDLORD DELAY IN COMPLETION OF INITIAL
IMPROVEMENTS. Subject to the conditions herein set forth, the anticipated
Delivery Date is September 1, 1998, meaning that, as provided in Section 1.2(a),
the Initial Improvements are to be Substantially Completed by such date. In the
event that, due to causes other than Permitted Delays, the Initial Improvements
are not Substantially Completed on September 1, 1998, then Contractor, but not
Landlord, shall be liable to Tenant for liquidated damages in the amount of Two
Thousand Five Hundred and 00/100ths Dollars ($2,500.00) for each day between (i)
September 1, 1998, and (ii) the first to occur of (y) the Delivery Date, and (z)
June 1, 1999. The effect of a Permitted Delay (determined pursuant to Section
2.4 hereof) shall cause the Delivery Date and the aforesaid June 1, 1999 date to
be extended by the duration so determined. The parties hereto have fully
negotiated the provisions of this Section 2.6 with respect to liquidated
damages, as well as the balance of the terms, provisions and conditions of this
Lease, free from any duress or other undue influence. Having determined that the
actual amount of any losses which Tenant would incur as a result of any delay in
the Initial Term Commencement Date, would be difficult, if not impossible, to
ascertain, the parties have, independently and in good faith, determined that
the foregoing liquidated damages are a fair and reasonable estimation of and
basis for any such losses, and that the liability thereof shall be borne solely
by Contractor, and not by Landlord. Accordingly, in the event of any such delay,
subject to the conditions set forth above, and anything in this Lease to the
contrary notwithstanding, the foregoing liquidated damages shall be the sole
obligation of Contractor (and Landlord shall have no liability) in the event of
any such delay, and shall be in lieu of any other rights or remedies which
Tenant would otherwise have at law or in equity. Anything in this Lease to the
contrary notwithstanding, Landlord shall have no liability or obligation in the
event of any such delay. Notwithstanding the foregoing, if the Initial
Improvements are not Substantially Completed prior to August 31, 1999 (which
date shall be subject to extensions resulting only from a Tenant Extension,
only, and not for other Permitted Delays), Tenant, pursuant to written notice
thereafter to Landlord and Contractor, may terminate this Lease, in which event
this Lease shall thereafter become null and void and of no further force and
effect, except for the obligation of Contractor to pay the liquidated damages
provided in this Section 2.6 shall survive such termination.

                                       12

     SECTION 2.7 WARRANTY. Subject to Section 2.3 hereof with respect to
compliance with the ADA and Tenant's obligations in regard thereto, Landlord and
Contractor warrant to Tenant, for a period of one (1) year from the Delivery
Date ("Initial Improvements Warranty Period"), that the Initial Improvements
shall be constructed in accordance with the provisions of section 2.3, and in
substantial compliance with the Final Plans, and shall be free from defects in
workmanship or materials. After the conclusion of the Initial Improvements
Warranty Period, Landlord or Contractor, as the case may be, shall assign and
transfer to Tenant all assignable (without cost to Landlord or Contractor)
warranties then in effect which were given to Landlord or Contractor in the
first instance. Landlord and Contractor shall use their respective reasonable
commercial efforts to furnish to Tenant three (3) copies of any and all service
contracts, warranties, equipment specifications, manufacturers' information and
operating instructions in connection with the Initial Improvements, as the same
may be reasonably available to Landlord or Contractor from their respective
suppliers. If, during the Initial Improvements Warranty Period, Tenant notifies
Landlord and Contractor, in writing, of defective workmanship or materials in
the construction of the Initial Improvements, Landlord and Contractor shall
promptly cause such defect to be corrected by the repair or replacement thereof,
as reasonably necessary.

     The warranty which is provided hereunder is limited in certain respects,
and is conditioned on the following:

     (a)  Tenant shall use the Initial Improvements only in accordance with the
          design capacities and criteria established therefor. Tenant
          acknowledges that any misuse thereof may void the warranty hereunder,
          and may void any manufacturers' or other warranties which may be
          assigned to Tenant hereunder.

     (b)  In addition to the foregoing, the warranty hereunder shall not extend
          to the electrical systems, plumbing systems, heating, ventilating and
          air conditioning systems, fire protection systems or other mechanical
          systems servicing the Initial Improvements, unless such systems are
          maintained and operated in compliance with the manufacturers'
          specifications therefor by those professionals specified by such
          manufacturers' specifications.

     (c)  Any and all work required to be performed under this Section 2.7
          ("Initial Improvements Warranty Work") shall not in any way include,
          or require Landlord or Contractor to perform, any routine or
          appropriate regular maintenance of Landlord's Improvements required to
          be performed by Tenant during the Initial Improvements Warranty Period
          as part of Tenant's Repairs and Maintenance (as such term is defined
          in Section 6.2 hereof).
 
     (d)  The warranty hereunder specifically excludes (and Tenant waives any
          claims, and shall cause its insurer to waive any and all subrogation
          claims, with respect to) any and all indirect or consequential
          damages, including, without limitation, damages to Tenant's products,
          equipment or other personal property which may be located within the
          Demised Premises. Tenant hereby acknowledges and agrees that it has
          acquired, or will acquire,

                                       13
<PAGE>
 
          and will maintain, appropriate amounts of insurance in order to manage
          such risks.

     SECTION 2.8 PUNCH LIST. As a condition of and prior to the Architect
issuing a certificate to Tenant of the Substantial Completion of the Initial
Improvements (or of the Expansion Improvements by the Expansion Architect, if
applicable), Landlord, ten (10) days prior to the date Landlord reasonably
believes the Initial Improvements (or Expansion Improvements, if applicable)
will be Substantially Complete, shall so advise Tenant, in writing. Promptly
following such notice, Landlord, Contractor, Tenant and Architect (or the
Expansion Architect in the instance of the Expansion Improvements, if
applicable) shall make a joint physical inspection of the Initial Improvements
(or of the Expansion Improvements, if applicable) to list the items of punch
list work to be completed ("Punch List Items") and the duration of time that
shall be afforded to complete the same, subject to Permitted Delays. Punchlist
List Items shall include minor corrective or minor incomplete items in respect
to the Initial Improvements (or Expansion Improvements, if applicable). In the
event Landlord, Contractor and Tenant are unable to agree on the Punch List
Items or the time within which they shall be completed, the Architect's (or that
of the Expansion Architect, if applicable) determination shall be binding on the
Landlord, Contractor and Tenant, which determination in respect to which items
are included shall based solely on the determination of whether the item in
question was constructed in substantial conformity with the Final Plans (or the
Final Expansion Plans, if applicable). When the list of Punchlist List Items are
determined as aforesaid, Contractor, in the instance of the Initial
Improvements, and the Landlord, in the instance of the Expansion Improvements,
shall deliver, in writing, its unconditional promise to complete, subject to
Permitted Delays, the applicable Punch List Items within thirty (30) days
thereafter, or such longer period of time determined as aforesaid. In the event
that the Contractor fails to complete the Punch List Items within the times
determined as aforesaid, then the Tenant, following fifteen (15) days prior
written notice to the Landlord, shall have the right to complete the Punch List
Items and deduct from the Base Rent a sum equal to Tenant's direct, out of
pocket costs incurred in completing such incomplete Punch List Items, plus an
administrative fee equal to ten percent (10%) of such costs.

     SECTION 2.9 INDEMNITY.

     (a)  Indemnity for Liens.  Landlord and Contractor (however, in the case of
          -------------------                                                   
Contractor, with respect to the Initial Improvements only) shall indemnify and
save Tenant, and its partners, directors, officers, shareholders, contractors,
subcontractors, sub-subcontractors, agents and employees, harmless from and
against any and all direct (but not indirect or consequential) liability, loss,
cost or damage, including, without limitation, reasonable attorneys' fees,
incurred or sustained by any of them in connection with any claim, lien, charge,
encumbrance or action brought, maintained or filed by any party for any labor
performed or materials furnished for or in connection with the Initial
Improvements (or the Expansion Improvements, if applicable), who claim through
or under Landlord or Contractor.

     (b)  Indemnity for Personal Injury and Property Damage.  Further, Landlord
          -------------------------------------------------                    
and Contractor (however, in the case of Contractor, with respect to the Initial
Improvements only) shall indemnify and save Tenant, and its partners, directors,
officers, shareholders, contractors, subcontractors, sub-subcontractors, agents
and employees, from and against all direct (but not

                                       14
<PAGE>
 
indirect or consequential) liability, loss, cost or damage, including, without
limitation, reasonable attorneys' fees, incurred or sustained by any of them,
except to the extent caused in whole or in part by the negligence or willful
misconduct of Tenant, or its partners, directors, officers, shareholders,
contractors, subcontractors, sub-subcontractors, agents, employees or invitees,
arising out of or resulting from the performance of any work in connection with
the construction of the Initial Improvements (or the Expansion Improvements, if
applicable); provided, however, that any such loss, cost or damage must be (i)
attributable to bodily injury, sickness, disease or death, or due to injury to
or destruction of tangible property (other than Landlord's Improvements), and
(ii) caused in whole or in part by the negligent or intentional act of
Contractor (with respect to the Initial Improvements only) or Landlord, or any
of their respective partners, directors, officers, shareholders, contractors,
subcontractors, sub-subcontractors, Mortgagees (as such term is defined in
Section 14.2 hereof), agents or employees, or anyone for whose acts any of them
may be liable. Notwithstanding the foregoing, except to the extent caused in
whole or in part by the negligence or willful misconduct of Tenant or its
partners, directors, officers, shareholders, contractors, subcontractors, sub-
subcontractors, agents, employees or invitees, if Tenant suffers a liability,
loss, cost or damage to an unrelated third party that is caused in whole or in
part by the negligence or intentional act of those parties set forth in clause
(ii) above, the scope of Landlord's or Contractor's liability hereunder shall
not be limited as provided in clause (i) above.

     (c)  Required Notification by Tenant.  Tenant shall promptly notify
          -------------------------------                               
Contractor (with respect to the Initial Improvements only) and Landlord of any
claim under an indemnity contained in this Section 2.9 of which Tenant has
knowledge, in such time so as to avoid prejudice to Contractor or Landlord.

     SECTION 2.10  EARLY ACCESS.


     (a)  Early Access.  Prior to the Substantial Completion of the Initial
          ------------                                                     
Improvements (or the Expansion Improvements, if applicable), and provided that
the Township or other governmental authority having jurisdiction does not
prohibit the same, Landlord shall provide Tenant with early access to the
Initial Improvements (or the Expansion Improvements, if applicable), including,
without limitation, access to and the use of loading docks, elevators,
construction hoists, electrical service and the like, for the purposes of
allowing separate contractors engaged by Tenant to install or construct therein
(to the extent then completed) such items for which Landlord and Contractor are
not responsible hereunder (together, "Tenant Work"); provided, however, that no
Tenant Work may be performed without the prior written consent of Landlord,
which consent may be conditioned on the submission of plans, specifications,
acceptable arrangements for security and other safety precautions, and other
details regarding the proposed Tenant Work, and other reasonable arrangements in
connection with scheduling, but shall not be otherwise unreasonably withheld or
delayed. Further, any and all Tenant Work shall be prosecuted and shall in all
instances be subject to the conditions and covenants pertaining to New Work (as
such term is defined in Section 17.1 hereof) which are set forth in Section 17.1
hereof. The terms, provisions and conditions of Section 2.5(b)(i) hereof and all
other terms, provisions and conditions of this Lease pertaining to Tenant
Extensions shall apply in connection with Tenant's exercise of its rights of
early access under this Section 2.10 and any Tenant Work. In the event Tenant's
prosecution of any Tenant Work unreasonably interferes with any work being
performed by or on behalf of Landlord, Landlord (or Contractor, in the instance
of the Initial Improvements) shall give written notice to Tenant of such
interference as provided in Section 2.5(c) hereof.

                                       15
<PAGE>
 
     The rights of Tenant to early access pursuant to this Section 2.10 are
hereinafter referred to as "Early Access." Landlord may, at any time, suspend
Tenant's rights to Early Access hereunder, in the event that Landlord or
Contractor reasonably determines that such Early Access or any Tenant Work is
unreasonably interfering with the construction of Landlord's Improvements, is
creating security or safety risks or is otherwise not in substantial conformance
with the conditions on which the Early Access was granted in the first instance.

     As part of Tenant Work, Landlord acknowledges and agrees that Tenant, by
separate contractors, shall be installing cables, wiring, and certain other
equipment and facilities for Tenant's voice data fiber optics, security systems
and other systems which are required to be, or are most efficiently, installed
during the pendancy of construction of the Initial Improvements (or Expansion
Improvements). Landlord shall coordinate with Tenant such installations by
Tenant of the foregoing systems pursuant to a schedule that Contractor (or
Landlord, in the instance of the Expansion Improvements) shall timely provide to
Tenant. Such schedule will permit Tenant to reasonably complete such
installations in as an efficient, timely manner in respect to the ongoing
construction of the Landlord's Improvements as is reasonably possible without
unreasonable interference to the Contractor (or Landlord, as aforesaid) or
unreasonable interference from the Contractor (or Landlord, as aforesaid). In
addition, as part of Tenant Work, Landlord acknowledges and agrees that Tenant,
by separate contractors, shall be installing furniture, assembling work station
partitions and performing associated work station partition electrical work,
which Tenant shall be permitted to undertake, without interference from the
Contractor (or Landlord, as aforesaid), not less than thirty (30) days prior to
the Delivery Date (or Expansion Delivery Date).

     Anything in this Section 2.10 to the contrary notwithstanding, Tenant shall
not commence the conduct of any business from the Initial Improvements prior to
the Delivery Date, or from the Expansion Improvements until the Expansion
Delivery Date.

     (b) Tenant Cooperation.  As a condition precedent to exercising its right
         ------------------                                                   
to Early Access hereunder and to entering into contracts with any separate
contractors described in Section 2.10(a) hereof, Tenant shall (i) provide to
Ticor Title Insurance Company, or other title insurer selected by Landlord, such
indemnities, hold harmless agreements or other similar undertakings or
reasonable assurances with respect to such separate contractors' lien claims, as
Landlord may reasonably require from time to time in order to induce such title
insurer to issue its interim and final certifications to Landlord's lender(s)
providing construction financing, if any, and to insure over possible lien
claims which such title insurer may otherwise raise as exceptions to title on an
owner's or lender's title insurance policy; and (ii) provide to Landlord and its
Mortgagees and insurers, such certificates of insurance, waivers of subrogation
and other documentation from Tenant and from Tenant's contractors,
subcontractors and sub-subcontractors as Landlord or its Mortgagees or insurers
may, from time to time, reasonably request. Tenant shall also comply with such
other reasonable requests as Landlord, Contractor or such title insurer or other
insurers may require in connection with any such separate contract(s).

     (c) Tenant Indemnity.  Tenant shall indemnify, defend and save Landlord,
         ----------------                                                    
Contractor and their respective partners, directors, officers, shareholders,
contractors, subcontractors, sub-subcontractors, Mortgagees, agents and
employees, harmless from and against any and all liability, loss, cost or
damage, including, without limitation, reasonable attorneys' fees and court
costs, incurred or sustained by any of them in connection with any claim, lien,
charge, encumbrance or action brought, maintained or filed by any party for any
labor performed or materials furnished for or in connection with the Land, the
Building or the Demised Premises, or any portion thereof, who claim by, through
or under Tenant. Further, Tenant shall, to the fullest extent permitted by
applicable law, indemnify, defend and save Landlord, Contractor and their
respective partners, directors, officers, shareholders, contractors,
subcontractors, sub-subcontractors, Mortgagees, agents and employees, harmless
from and against any and all liability, loss, cost or damage, including, without
limitation, reasonable attorneys' fees and court costs, 

                                       16
<PAGE>
 
incurred or sustained by any of them, except to the extent caused in whole or in
part by the negligence or willful misconduct of Landlord, Contractor or their
respective partners, directors, officers, shareholders, contractors,
subcontractors, sub-subcontractors, Mortgagees, agents or employees, arising out
of or resulting from the performance by Tenant, or its partners, directors,
officers, shareholders, contractors, subcontractors, sub-subcontractors, agents
or employees, of any work in connection with the construction of any of the
Improvements; provided, however, that any such loss, cost or damage must be (i)
attributable to bodily injury, sickness, disease or death, or due to injury or
destruction of tangible property, and (ii) caused in whole or in part by the
negligent or intentional act of Tenant or its partners, directors, officers,
shareholders, contractors, subcontractors, sub-subcontractors, agents or
employees, or anyone directly or indirectly employed by any of them, or anyone
for whose acts any of them may be liable. Landlord or Contractor shall promptly
notify Tenant of any claim under an indemnity contained in this Section 2.10(c)
of which Landlord or Contractor, as applicable, has knowledge, in such time so
as to avoid prejudice to Tenant. Notwithstanding the foregoing, except to the
extent caused in whole or in part by the negligence or willful misconduct of
Landlord or Contractor or their partners, directors, officers, shareholders,
contractors, subcontractors, sub-subcontractors, agents, employees or invitees,
if Landlord or Contractor or Mortgagee suffers a liability, loss, cost or damage
to an unrelated third party that is caused in whole or in part by the negligence
or intentional act of those parties set forth in clause (ii) above, the scope of
Tenant's liability hereunder shall not be limited as provided in clause (i)
above.

     SECTION 2.11   ARBITRATION OF CERTAIN MATTERS.      Landlord, Tenant and
Contractor hereby appoint any one of those individuals set forth on Exhibit 2.11
hereof ("Arbitrator") to act as the arbitrator in respect to those disputes
specifically set forth in Sections 2.5(c) and 4.1 of this Lease. To the extent
that disputes arise among the parties that are not specifically provided in this
Lease as being the subject for resolution pursuant to provisions of this Section
2.11, the parties shall be permitted to pursue their respective remedies at law
or in equity, except as otherwise limited herein. Landlord and Tenant shall
each, in good faith, agree on the substitution (if any) of those individuals set
forth on Exhibit 2.11 that Landlord and Tenant desire to act as the Arbitrator
in respect to the Expansion Improvements. Such substitution(s) shall be
determined by Landlord and Tenant within thirty (30) days following Landlord's
receipt of the Expansion Notice, if any. Such substitute individual(s) that may
act as the Arbitrator shall have those qualifications and experience (duration,
scope and geographic familiarity) that are reasonably similar to that of the
individual(s) listed on said Exhibit 2.11 for whom a substitution is being made.
When any disputing party desires to submit a dispute set forth in Section 2.5(c)
hereof to the Arbitrator for the Arbitrator's binding determination, such
disputing party shall notify, in writing, the other party(ies) thereto of such
intention and shall identify the individual from Exhibit 2.11 such noticing
party selects to act as the Arbitrator. Within five (5) days following such
notice, each of the disputing parties shall submit to the Arbitrator and the
other 

                                       17
<PAGE>
 
disputing party(ies) such party's determination of the manner in which such
dispute should be resolved ("Submitted Resolution"). Within five (5) days
following the Arbitrator's receipt of the Submitted Resolutions, the Arbitrator
shall select one of the Submitted Resolutions that the Arbitrator, in his sole
and exclusive judgment, determines appropriate. Such selection shall be binding
on the parties to the subject dispute. The party whose Submitted Resolution was
not selected shall pay for all of the charges of the Arbitrator in respect to
such dispute.

                                  ARTICLE 2A

                         EXPANSION OF DEMISED PREMISES


     SECTION 2A.1   OPTION TO EXPAND.


     (a)  Exercise of Right to Expand.  Subject to Section 2A.8 hereof, and
          ---------------------------                                      
provided that Tenant is not then in Default hereunder, Tenant shall have the
right to cause Landlord to expand the Initial Improvements, by means of the
Expansion Improvements, in accordance with this Article 2A ("Expansion Option").
The Expansion Option shall be exercised, if at all, and shall be effective only
if exercised in accordance with the terms, provisions and conditions of this
Article 2A. The "Expansion Improvements" shall mean that additional office
space, if any, consisting of not less than 40,000 gross square feet and nor more
than a maximum of 90,000 gross square feet, together with required parking
therefor to be built onto the parking for the Initial Improvements, contiguous
to the Initial Improvements and as depicted on Exhibit 2A.1(a) attached hereto
and made a part hereof. Landlord shall construct the Expansion Improvements, or
cause the Expansion Improvements to be constructed, on the Land in accordance
with this Article 2A, pursuant to Tenant's exercise of the Expansion Option.

     (b)  Exercise of Right to Expand; Delivery of Expansion Notice.  Provided
          ---------------------------------------------------------           
that Tenant is not then in Default hereunder, Tenant may exercise the Expansion
Option by delivering to Landlord written notice ("Expansion Notice") of Tenant's
direction to Landlord to prepare the components of the Final Expansion Base
Building Plans in accordance with the provisions of Section 2.2(b) hereof. In
order to be effective, and as a strict condition precedent to Tenant's rights
under this Article 2A, Tenant's Expansion Notice must be received by Landlord on
or before the last business day of the ninety-sixth (96th) month of the Initial
Term.

     (c)  Specifications of Expansion Improvements.  In addition to the
          ----------------------------------------                     
requirements set forth in Section 2A.1(d) hereof, Tenant's Expansion Notice
shall contain Tenant's specifications for the Expansion Improvements, which
shall be consistent with the depiction of the Expansion Improvements set forth
on Exhibit 2A.1(a) attached hereto and made a part hereof and shall otherwise be
reasonably satisfactory to Landlord and Tenant. Such specifications, among other
things, must be in compliance with all then-applicable Park covenants and all
federal, state, Township or other local statutes, laws, ordinances, rules and
regulations.

     (d)  Contents of Expansion Notice.  Tenant's Expansion Notice to Landlord
           ----------------------------                                        
shall contain the following information:


     (i)  Such relevant data concerning the desired Expansion Improvements
          (provided that the Expansion Improvements shall be in conformity with,
          among other things, the clear height of the Initial Improvements, and
          in 

                                       18
<PAGE>
 
          conformity with the architecture, engineering and general aesthetics
          of the Initial Improvements), in sufficient detail, all as may be
          necessary to enable Landlord to determine the Expansion Costs (as such
          term is defined in Section 3.1(h) hereof), provided that in the event
          that the Landlord advises the Tenant that Tenant's Expansion Notice
          does not provide sufficient detail, as required hereunder, the
          timeliness of the Tenant's Expansion Notice shall not be invalidated,
          if Tenant promptly provides Landlord with additional detail reasonably
          necessary for Landlord to determine the Expansion Costs; and

     (ii) The date on which Tenant requests that the Expansion Improvements be
          completed and ready for occupancy for Tenant's use, which date shall
          in no case be earlier than twelve (12) months after Tenant's approval
          of the Final Expansion Plans and shall not be later than the last day
          of the Initial Term.

     (e)  Landlord's Proposal.  Within sixty (60) days after Landlord's receipt
          -------------------                                                  
of Tenant's Expansion Notice, Landlord shall consult with Tenant concerning
Tenant's specific requirements in regard to its desired expansion, and within
such sixty(60)-day time period shall notify Tenant, in writing, of the non-
binding, total estimated Expansion Costs which will be incurred in planning and
constructing the Expansion Improvements.

     (f)  Tenant's Notice to Proceed.  Within sixty (60) days after receipt of
          --------------------------                                          
Landlord's written notification as to the Expansion Costs, as provided in
Section 2A.1(e) hereof, Tenant shall notify Landlord in writing, either that (i)
Tenant authorizes Landlord to proceed with the preparation of the components of
the Final Expansion Base Building Plans, and the commencement of construction of
the Expansion Improvements ("Notice to Proceed"); or (ii) Tenant desires to
revise the specifications for the Expansion Improvements to reduce the estimated
Expansion Costs to an amount satisfactory to the Tenant (in which event the
Tenant shall submit revised specifications within sixty (60) days from the
receipt by Landlord of Tenant's notice under this item (ii), and Landlord shall
thereafter consult with Tenant and provide revised estimated Expansion Costs
within sixty (60) days in accordance with Section 2A.1(e), and Tenant shall
thereafter provide notice to Landlord in accordance with this Section
2A.1(f));or (iii) Tenant elects not to expand. If Tenant fails to deliver its
Notice to Proceed to Landlord within the aforesaid sixty (60)-day period, then
Tenant shall be automatically and conclusively deemed to have elected not to
expand. Anything in this Lease to the contrary notwithstanding, Tenant may not
give an Expansion Notice more than three (3) times, nor more than once during
each calendar year, and Tenant shall not be permitted to request, more than
twice in respect to any Expansion Notice, the revisions of the specifications
for the Expansion Improvements in order to reduce the estimated Expansion Cost
as provided in clause (ii) above.

     (g)  Automatic Election to Exercise Renewal Terms.  Anything in this Lease
          --------------------------------------------                         
to the contrary notwithstanding, in the event that Tenant delivers its Notice to
Proceed, then, depending on the date on which of the resulting Expansion
Commencement Date occurs, Tenant shall automatically and conclusively be deemed
likewise to have exercised its option for such full or partial Renewal Terms
such that as of the Expansion Commencement Date, the remaining Term of this
Lease shall be ten (10) years and shall expire at 11:59 P.M., prevailing time,
on the day preceding the tenth (10th) anniversary of the Expansion Delivery
Date, provided, however, the 

                                       19
<PAGE>
 
Tenant shall continue to have the right to exercise its option for any remaining
Renewal Terms (or portions thereof) which remain beyond said ten (10) year
additional Term which shall come into effect as provided under this Section
2.A.1(g); provided, further, that if the remaining portion of a Renewal Term
after the extension of the Term of this Lease for ten (10) years from the
Expansion Delivery Date shall be less than one (1) year, then the ten (10) year
term from the Expansion Delivery Date shall be further extended to include the
remaining portion of the Renewal Term which is less than one (1) year. For
example, if the Tenant delivers its Notice to Proceed and the resulting
Expansion Delivery Date is the sixth anniversary date of the Initial
Commencement Date, then the Term of the Lease as of the Expansion Delivery Date
shall be for a period of ten (10) years and the Tenant shall thereafter have
remaining a Second Renewal Term of four (4) years, a Third Renewal Term of five
(5) years and a Fourth Renewal Term of four (4) years and eleven (11) months.

     SECTION 2A.2   PREPARATION OF EXPANSION PLANS.  Promptly after Landlord's
receipt of the Notice to Proceed, and subject to Section 2A.8 hereof, Landlord
shall cause to be prepared and delivered to Tenant all of the components of the
Final Expansion Base Building Plans, prepared by a licensed Pennsylvania
architect and one or more licensed Pennsylvania engineers, reasonably acceptable
to Tenant ("Expansion Architect"), and in substantial conformity with the
Expansion Notice and in substantial conformity with the style, design and
exterior colors and materials as the Final Plans. The Final Expansion Base
Building Plans shall be in a form sufficiently complete to enable the issuance
of a building permit by the Township for the construction of the base building
portion of the Expansion Improvements. In addition, as soon as practicable,
after Tenant's delivery of the Notice to Proceed, Landlord shall cause the Final
Expansion Plans to be delivered to Tenant, which shall contain the same
components as the Final Initial Interior Build-Out Plans, shall be in
substantial conformity with the Expansion Notice, and shall be reasonably
satisfactory to Tenant.

     When each of the components of the Final Expansion Base Plans has been
prepared and approved in accordance with this Section 2A.2 and Section 2.2(b)
hereof, Tenant and Landlord shall each affix their respective signatures or
initials to each page comprising such component. Thereafter, such approved
components shall constitute the "Final Expansion Plans" and shall be deemed to
become attached to and made a part of this Lease as identified in Exhibit 2A.2.

     SECTION 2A.3   EXPANSION COMMENCEMENT DATE.  The "Expansion Commencement
Date" and the "Expansion Delivery Date" shall be the later of (a) the date set
forth in Tenant's Expansion Notice (in accordance with Section 2A.1(d)(ii)
hereof), or (b) the date on which the Expansion Improvements are Substantially
Completed. Notwithstanding the foregoing, if the Expansion Architect has
certified in writing that, as of a date certain set forth in such written
certification, the Expansion Improvements would have been Substantially
Completed, but for a Tenant Extension, then the Expansion Improvements shall
nevertheless be deemed to be Substantially Completed for purposes of determining
the Expansion Commencement Date and the payment of the Expansion Improvements
Base Rent (as such term is defined in Section 3.1(a) hereof) hereunder on the
date certain set forth in the aforesaid certification.


     SECTION 2A.4   SCOPE OF WORK; EXPANSION IMPROVEMENTS.  Weather permitting,
promptly following the completion of all components of the Final Expansion
Plans, Landlord shall furnish or cause to be furnished, at Landlord's sole cost
and expense, all the material, labor and equipment necessary for the
commencement and completion of construction of the Expansion Improvements. 

                                       20
<PAGE>
 
The Expansion Improvements shall be constructed in a good and workmanlike manner
in substantial accordance with the Final Expansion Plans. In the event that any
materials specified in the Final Expansion Plans are not reasonably available to
Landlord or its contractor, Landlord and such contractor reserve the right to
substitute materials of higher or equal quality.

     SECTION 2A.5   EXPANSION CHANGE ORDERS.  Tenant shall be allowed to request
Change Orders, and shall be deemed to have requested Change Orders, with respect
to the Expansion Improvements as provided in Section 2.4 hereof.

     SECTION 2A.6   WARRANTY AS TO EXPANSION IMPROVEMENTS.  Landlord shall
warrant to Tenant, for a period of one (1) year after Expansion Commencement
Date of the Expansion Improvements ("Expansion Improvements Warranty Period"),
that the Expansion Improvements shall be constructed in substantial compliance
with the Final Expansion Plans, and shall be free from defects in workmanship or
materials. After the conclusion of the Expansion Improvements Warranty Period,
Landlord or its contractor, as the case may be, shall assign and transfer to
Tenant all assignable (without cost to Landlord or its contractor) warranties
then in effect with respect to the Expansion Improvements which were given to
Landlord or its contractor in the first instance. If during the Expansion
Improvements Warranty Period, Tenant notifies Landlord, in writing, of defective
workmanship or materials in the construction of the Expansion Improvements,
Landlord shall promptly cause such defect to be corrected by the repair or
replacement thereof, as reasonably necessary. The foregoing warranty is subject
to same terms, conditions, undertakings and limitations as set forth in Section
2.7 hereof.

     SECTION 2A.7   EXPANSION PUNCH LIST.  The inspection of the Expansion
Improvements and the determination of Punch List Items with respect thereto
shall be conducted and determined in the manner set forth in Section 2.2 hereof,
to the extent applicable.

     SECTION 2A.8   LIMITATION ON LANDLORD'S OBLIGATIONS.  Anything in this
Article 2A or elsewhere in this Lease to the contrary notwithstanding,
Landlord's obligations under this Article 2A are expressly made contingent on
(a) Tenant's accepting Landlord's proposal as to the Expansion Costs; and (b)
all necessary approvals, consents and permits being issued or obtained in
connection with the Expansion Improvements, which approvals, consents and
permits at the time of the proposed expansion are required by the Township or
any and all other governmental authorities then having jurisdiction over the
Demised Premises. In the event that Landlord is not able to obtain one or more
of the aforesaid approvals, consents or permits, Landlord shall notify Tenant
thereof, in writing, as promptly as practicable.

                                     RENT

     SECTION 3.1    BASE RENT.


     (a)  Payment of Base Rent.  Tenant shall pay to Landlord's agent, Walsh,
          --------------------                                               
Higgins & Company, Suite 800, 101 East Erie Street, Chicago, Illinois 60611, or
at such other place as Landlord may from time to time designate in writing, in
coin or currency which, at the time of payment, is legal tender for private or
public debts of the United States of America, annual base rent ("Base Rent")
during the Term, as set forth in this Section 3.1. Base Rent shall be comprised
of (i) 

                                       21
<PAGE>
 
Base Rent with respect to the Initial Improvements ("Initial Improvements Base
Rent"), (ii) Base Rent with respect to the Expansion Improvements ("Expansion
Improvements Base Rent"), and (iii) Change Order Base Rent, if any. Base Rent
shall be payable in equal monthly installments, each in advance, on or before
the first day of each and every calendar month during the Term.

     (b)  Initial Improvements Base Rent During Initial Term. The annual Initial
          --------------------------------------------------  
Improvements Base Rent during each twelve (12)-month period ("Lease Year")
during the Initial Term and the monthly Initial Improvements Base Rent during
the first twelve (12) months of the Initial Term is set forth on Exhibit 3.1(b)
attached hereto and made a part hereof. After the first twelve (12) months of
the Initial Term, the Initial Improvements Base Rent shall be paid in equal
monthly installments. In addition, the Initial Improvements Base Rent shall
include any Change Order Base Rent determined in accordance with the provisions
of Section 2.4 hereof.

     (c)  Initial Improvements Base Rent During Renewal Terms. If Tenant elects,
          ---------------------------------------------------  
or is deemed hereunder to have elected, to renew this Lease for any of the
Renewal Terms, then the Initial Improvements Base Rent payable hereunder during
each Lease Year in each such Renewal Term shall be equal to ninety-three percent
(93%) of the Fair Market Base Rent (as such term is defined in Section 3.1(f)
hereof) multiplied times fair market periodic increases ("Fair Market
Escalator"). In no instance however, shall the Initial Improvements Base Rent
plus Change Order Base Rent during the applicable Renewal Term be less than the
Initial Improvements Base Rent plus Change Order Base Rent paid by Tenant during
the Initial Term or during the preceding Renewal Term, as applicable.

     (d)  Expansion Improvements Base Rent During Initial Term. The Expansion
          ----------------------------------------------------                
Improvements Base Rent during the Initial Term shall be determined in accordance
with Section 3.1(g) hereof.

     (e)  Expansion Improvements Base Rent During Renewal Terms. The Expansion
          -----------------------------------------------------                
Improvements Base Rent during the Renewal Terms shall be determined in
accordance with Section 3.1(g) hereof.

     (f)  Determination of Fair Market Base Rent. As noted in Section 3.1(c)
          --------------------------------------                             
hereof, the Initial Improvements Base Rent during any of the Renewal Terms shall
be equal to ninety-three percent (93%) of the fair market base rent ("Fair
Market Base Rent"), as determined in accordance with this Section 3.1(f),
multiplied by the Fair Market Escalator, if any. At least one hundred twenty
days (120) days prior to the last day of the Initial Term or the last day of the
First Renewal Term, as applicable, Landlord shall notify Tenant in writing of
Landlord's proposed Fair Market Base Rent and Fair Market Escalator, if any, for
the Demised Premises for the applicable Renewal Term ("Landlord's Proposal").
Within thirty (30) days after the receipt of Landlord's Proposal, Tenant shall
advise Landlord, in writing, either that (i) Tenant accepts Landlord's Proposal,
or (ii) Tenant chooses to have the Initial Improvements Base Rent plus Change
Order Base Rent for the applicable Renewal Term determined by appraisal. If
Tenant chooses Landlord's Proposal, the Initial Improvements Base Rent and
Change Order Base Rent for the applicable Renewal Term shall be that set forth
in Landlord's Proposal. If Tenant fails so to notify Landlord within thirty (30)
days after Tenant's receipt of Landlord's Proposal, Tenant shall be
automatically and conclusively deemed to have accepted Landlord's Proposal.

                                       22
<PAGE>
 
     If Tenant chooses to have the Initial Improvements Base Rent and Change
Order Base Rent determined by appraisal, such appraisal shall be determined as
hereinafter provided based upon such criteria as the appraisers (described
below) deem appropriate, which determination shall be binding on Landlord and
Tenant. Such criteria shall include, without limitation, (i) the current use of
the Demised Premises; (ii) the location, quality and age of the Building; (iii)
the size and condition of the Demised Premises; (iv) the extent of the
improvements within the Demised Premises; (v) the extent of the services and
amenities provided to Tenant under this Lease; (vi) lease concessions, such as
lease takeovers/assumptions, so-called expense stops, rental abatements and
commissions (paid or not required to be paid) that are being offered by other
first-class office buildings in the geographic area in which the Demised
Premises are located; (vi) the duration of the applicable Renewal Term; (vii)
the distinction between a "gross" and a "net" lease; and (viii) rental rates and
escalation thereto, if any, then being charged for comparable premises in the
geographic area in which the Demised Premises are located. Further, if Tenant is
obligated to continue the payment of Special Assessments pursuant to Section 4.1
hereof during any of the Renewal Terms, or such obligation arises prior to a
Renewal Term and the obligation for Tenant to pay Special Assessments is known
prior to the commencement of the subject Renewal Term, then any appraisal to
determine the Initial Improvements Base Rent and Change Order Base Rent during
such Renewal Term shall not include, in the establishment of such Rents, the
value or benefit to the Demised Premises resulting from the public improvements
or benefits which are the subject of the subject Special Assessment.

     If Tenant elects to have the Initial Improvements Base Rent and Change
Order Base Rent determined by appraisal, Tenant's notice to Landlord thereof
shall also designate Tenant's independent appraiser. Within fifteen (15) days
after Tenant's designation, Landlord shall designate its independent appraiser
and shall notify Tenant thereof in writing. Within fifteen (15) days after
Landlord's designation, both appraisers shall mutually agree on the designation
of a third appraiser. Landlord shall pay all costs associated with the appraiser
designated by Landlord; Tenant shall pay all costs associated with the appraiser
designated by Tenant; and Landlord and Tenant shall share equally in all costs
associated with the appraiser designated by the other two appraisers. All three
appraisers shall be reputable, independent MAI certified real estate appraisers,
each of whom shall be knowledgeable and experienced in the appraisals of rents
for office buildings in the Harrisburg, Pennsylvania area.

     After their appointment, the appraisers shall be directed to determine
independently the Fair Market Base Rent and Fair Market Escalator for the period
for which the determination is being made. Within thirty (30) days after the
designation of the third appraiser, all three appraisals of the Fair Market Base
Rent and Fair Market Escalator, as applicable, shall be submitted, in writing,
to Landlord and Tenant. If two or all three of the appraisals shall be identical
in amount, the Initial Improvements Base Rent plus Change Order Base Rent for
the applicable Renewal Term shall be computed as aforesaid using such identical
amount. In the event no two of the appraisals are identical, the highest and the
lowest appraisal shall be disregarded and the Initial Improvements Base Rent
plus Change Order Base Rent for the applicable Renewal Term shall be computed as
aforesaid using such middle appraisal.

     If the Initial Improvements Base Rent plus Change Order Base Rent for the
applicable Renewal Term is not determined until after the commencement of the
applicable Renewal Term, Tenant shall continue to pay the Initial Improvements
Base Rent plus Change Order Base Rent 

                                       23
<PAGE>
 
equal to the Initial Improvements Base Rent plus Change Order Base Rent paid
during the Initial Term or during the preceding Renewal Term, as applicable.
When the Fair Market Base Rent and Fair Market Escalator, if applicable, are
determined as provided above, and if such determination is greater than the
Initial Improvements Base Rent plus Change Order Base Rent paid during the
Initial Term or during the preceding Renewal Term, as applicable, within thirty
(30) days following such determination, Tenant shall pay to Landlord the
deficiency of the Initial Improvements Base Rent plus Change Order Base Rent
theretofore paid, prorated from the commencement of the applicable Renewal Term
to the date of the determination of the Fair Market Base Rent and Fair Market
Escalator.

     (g)  Determination of Expansion Improvements Base Rent During Initial Term
          ---------------------------------------------------------------------
and Renewal Term.  The Expansion Improvements Base Rent shall be an annual
- ----------------                                                          
amount equal to the product of (i) the Expansion Costs, multiplied by (ii) 1.07
(representing a combined general contractor's and developer's fee), multiplied
by (iii) the greater of (A) ten and 50/100ths percent (10.50%), or (B) an annual
interest rate equal to three hundred seventy-five (375) basis points in excess
of the ten (10)-year United States Treasury Note Rate then most recently
announced by the United States Treasury as of the Expansion Commencement Date.
The Expansion Improvements Base Rent shall be in effect during the first twelve
(12) months after the Expansion Commencement Date. Thereafter, during the
balance of the Term (including any Renewal Terms that are elected by Tenant
after the expiration of the ten (10) years period subsequent to the Expansion
Delivery Date), the Expansion Improvements Base Rent shall be increased annually
by the lesser of (a) five percent (5%) per annum, and (b) seventy-five percent
(75%) of the percentage by which the United States, Bureau of Labor Statistic,
Consumer Price Index for All Items - All Urban Wage Earners and Clerical Workers
for the Philadelphia Area ("CPI Index") published nearest to the expiration of
each twelve (12) month period subsequent to the Expansion Commencement Date is
greater than the CPI Index most recently published prior to the Initial Term
Commencement Date.

     (h)  Definition of Expansion Costs.  The "Expansion Costs" shall be the
          -----------------------------                                     
aggregate of all payment obligations of those contracts for "hard costs" and
"soft costs" identified on Exhibit 3.1(h) attached hereto and made a part hereof
in connection with the development and construction of the Expansion
Improvements, which are incurred by or on behalf of Landlord in connection with
the construction of the Expansion Improvements. The Expansion Costs shall be
based on not less than three competitive bids obtained by the Landlord from
general contractors bidding the Expansion Improvement work on a lump sum basis.
The contract for the design and construction shall be awarded to the most
qualified bidder as mutually selected by Tenant and Landlord. Landlord shall
cause the construction of the Expansion Improvements on an "open-book" basis so
that Tenant shall have the opportunity to review and verify all of the component
elements that comprise the Expansion Costs. In addition, the Expansion Costs
shall include a sum ("Expansion Land Cost") equal to $264,000.00 escalated by
two percent (2%) per year, cumulatively, for each twelve (12)-month period, or
portion thereof, between the Initial Commencement Date and the date on which
Landlord receives Tenant's Notice to Proceed. Based upon the foregoing
computations, within fifteen (15) days after the Expansion Commencement Date,
Landlord shall advise Tenant, in writing, of the amount of the Expansion
Improvements Base Rent and its calculation thereof as provided above.

     SECTION 3.2.   PRORATION OF BASE RENT; ABSOLUTE NET. If the Initial Term or
any Renewal Term commences other than on the first day of a calendar month or
ends other than on the last day 

                                       24
<PAGE>
 
of a month, or if the Expansion Commencement Date is other than the first day of
a calendar month, the Initial Improvements Base Rent (or Expansion Improvement
Base Rent, as applicable) for such month shall be prorated accordingly. Except
as specifically provided herein, the Base Rent and the Expansion Improvement
Rent shall be absolutely net to Landlord so that this Lease shall yield, net to
Landlord, the Base Rent specified in Section 3.1 hereof.

     SECTION 3.3.   ADDITIONAL RENT. Except as expressly provided herein, and as
further provided in Section 4.1 hereof, in each year of the Term, all
Impositions (as such term is defined in Section 4.1 hereof), insurance premiums,
utility charges, maintenance, repair and replacement expenses, all expenses
relating to Compliance with Laws (as such term is defined in Section 7.1
hereof), and all other costs, fees, charges, expenses, reimbursements and
obligations of every kind and nature whatsoever relating to the Demised
Premises, which may arise or become due during the Term, or by reason of events
then occurring, shall be paid or discharged by Tenant as additional rent
(together, "Additional Rent"). Except as expressly provided herein, Tenant shall
indemnify and save Landlord, and its partners, directors, officers,
shareholders, contractors, subcontractors, sub-subcontractors, Mortgagees,
agents and employees, harmless from and against any and all loss, cost or
damage, including, without limitation, reasonable attorneys' fees, incurred or
sustained by any of them in connection with any and all of such Impositions,
insurance premiums, utility charges, maintenance, repair and replacement
expenses, all expenses relating to Compliance with Laws, and all other costs,
fees, charges, expenses, reimbursements and obligations. Base Rent and
Additional Rent are sometimes hereinafter collectively referred to as "Rent."

     SECTION 3.4    RENT PAYABLE WITHOUT PRIOR DEMAND; MAXIMUM RATE OF INTEREST.
Except as set forth herein, all payments of Base Rent and Additional Rent shall
be payable without previous demand therefor. In case of nonpayment by Tenant of
any item of Additional Rent payable to Landlord when the same is due, Landlord
shall have, in addition to all its other rights and remedies, all of the rights
and remedies available to Landlord under the provisions of this Lease or by law
as if in the case of nonpayment of Base Rent. The performance and observance by
Tenant of all the terms, covenants, conditions and agreements to be performed or
observed by Tenant hereunder shall be performed and observed by Tenant, at
Tenant's sole cost and expense.

     Except as provided in this Section 3.4, any installment of Base Rent or
Additional Rent payable to Landlord or any other charges payable by Tenant to
Landlord under the provisions hereof which shall not be paid within five (5)
days when due, shall bear interest at an annual rate equal to three (3)
percentage points per annum in excess of the rate of interest from time to time
announced by Harris Trust and Savings Bank, Chicago, Illinois (or similar
institution if such bank shall cease to exist or to publish such a rate) as its
corporate base rate of interest, but in no event in excess of the maximum lawful
rate permitted to be charged by Landlord against Tenant. Such rate of interest
is hereinafter referred to as the "Maximum Rate of Interest." Notwithstanding
the foregoing, Tenant shall be permitted, not more than once each calendar year
during the Term, to be late by not more than ten (10) days in the payment of
Base Rent or Additional Rent hereunder before interest shall commence to accrue
thereon as aforesaid.

                                   ARTICLE 4

                      PAYMENT OF TAXES, ASSESSMENTS, ETC.

<PAGE>
 
     SECTION 4.1    ADDITIONAL RENT.  Subject to the terms, provisions and
conditions of this Section 4.1, and except as expressly provided elsewhere in
this Lease, Tenant covenants and agrees to pay as Additional Rent, before any
fine, penalty, interest or cost may be added thereto for the nonpayment thereof,
all real estate taxes, special assessments, Tenant's allocable share of regular
and special assessments with respect to the Park for items such as, without
limitation, common area maintenance ("Park Assessments"), water rates and
charges, sewer rates and charges, including, without limitation, any sum or sums
payable for sewer or water capacity, charges for public utilities, insurance
premiums, street lighting, excise levies, licenses, permits, governmental
inspection fees (incurred after Substantial Completion of either or both of the
Initial Improvements or the Expansion Improvements, if applicable), other
governmental charges and all other charges or burdens of whatsoever kind and
nature (including, without limitation, costs, fees and expenses of complying
with any restrictive covenants or similar agreements to which the Demised
Premises are subject), incurred in the use, occupancy, operation, leasing or
possession of the Demised Premises (excluding any income taxes on the Base Rent
imposed on Landlord, it being the intent of the parties hereto that any tax on
the net income derived from the Base Rent payable in respect to the Demised
Premises imposed by any governmental authority shall be paid by Landlord),
without particularizing by any known name or by whatever name hereafter called,
and whether any of the foregoing be general or special, ordinary or
extraordinary, foreseen or unforeseen, which at any time during the Term may be
payable (together, "Impositions"). It is the intention of Landlord and Tenant
that Tenant will pay all Impositions directly to the person, entity, utility,
municipality or other body which is owed the Imposition; provided, however, that
upon Landlord's request from time to time, Tenant shall deliver receipts and
other reasonable evidence of its payment of any and all Impositions and other
items of Additional Rent paid to third parties. Except with respect to the
payment of real estate taxes (as provided below), if any Additional Rent is to
be paid by Tenant to Landlord (as opposed to being paid by Tenant to a third
party), then such payments shall be due thirty (30) days after Landlord has
invoiced Tenant therefor.

     All special (or similar) assessments or installments thereof (including,
without limitation, interest thereon) for public improvements or benefits which,
during the Term, shall be laid, assessed, levied or imposed upon or become a
lien upon the Demised Premises and which are payable at any time during the Term
shall hereafter be collectively referred to as "Special Assessments." In respect
to the public improvements or benefits that are the subject of a Special
Assessment(s), Landlord and Tenant shall agree on the useful life of such
improvements or benefits. In the event Landlord and Tenant cannot agree on such
useful life, the useful life shall be determined by the Arbitrator as provided
in Section 2.11 hereof, which determination shall be binding on Landlord and
Tenant. If such useful life is determined as aforesaid to be less than ten (10)
years or greater than twenty (20) years, notwithstanding such determination, the
useful life nonetheless shall be deemed to be, respectively, ten (10) years and
twenty (20) years. The aggregate amount of the subject Special Assessment that
has all or any portion thereof due and payable during the Term shall be
apportioned evenly over the number of years of the determined useful life.
Tenant shall pay, as part of the Additional Rent, those apportioned parts of the
subject Special Assessment (or prorated portion thereof) that are within the
Term. If the subject Special Assessment is due on a lump sum basis Landlord
shall pay such lump sum amount or if the subject Special Assessment has been
fully paid by Landlord, Tenant's apportioned part applicable thereto shall be
due and payable on the date (in the instance of any apportioned part being due
in the first year of the Initial Term) that is thirty (30) days subsequent to
the Delivery Date and each anniversary such date during the Term in which such
apportioned part is 

                                       26
<PAGE>
 
applicable. If the subject Special assessment is payable in installments,
Tenant's apportioned part shall be due and payable fifteen (15) days prior to
the date the applicable installment is due. Landlord shall pay all installments
of Special Assessments (including, without limitation, interest accrued on the
unpaid balance) which are payable prior to the commencement and after the
termination of this Lease.

     Except as hereinafter provided, Tenant shall pay all real estate taxes,
whether heretofore or hereinafter levied or assessed upon the Demised Premises,
or any portion thereof, which are due and payable during the Term (regardless of
the period to which such taxes relate).

     Anything in this Lease to the contrary notwithstanding, during each
calendar year during the Term (prorated as appropriate), Tenant shall from time
to time be obligated to pay its allocable share of the Park Assessments.

     SECTION 4.2    TAXES ON RENT.  Except for any tax on the net income derived
from the Base Rent, if at any time during the Term, any method of taxation shall
be such that there shall be levied, assessed or imposed on Landlord, or on the
Base Rent or Additional Rent, or on the Demised Premises, or any portion
thereof, in lieu of real property taxes, a capital levy, gross receipts tax or
other tax on the rents received therefrom, or a franchise tax, or an assessment,
gross levy or charge measured by or based in whole or in part upon such gross
Rents, Tenant, to the extent permitted by law, covenants to pay and discharge
the same. Anything in this Lease to the contrary notwithstanding, it is the
intention of the parties hereto that the Base Rent to be paid hereunder shall be
paid to Landlord absolutely net without deduction or charge of any nature
whatsoever, foreseeable or unforeseeable, ordinary or extraordinary, or of any
nature, kind or description, except as otherwise expressly provided in this
Lease. Nothing contained in this Lease shall require Tenant to pay any
municipal, state or federal net income or excess profits taxes assessed against
Landlord, or any municipal, state or federal business privilege, mercantile,
capital levy, estate, succession, inheritance or transfer taxes of Landlord, or
corporation franchise taxes imposed upon any corporate owner of the fee of the
Demised Premises.

     SECTION 4.3    RECEIPTS FOR IMPOSITIONS.  Tenant covenants to furnish
Landlord, within thirty (30) days of written request from Landlord, official
receipts of the appropriate taxing authority, or other appropriate proof
satisfactory to Landlord, evidencing the payment of any Imposition or other tax,
assessment, levy or charge payable by Tenant hereunder. The certificate, advice
or bill of the appropriate official designated by law to make or issue the same,
or to receive payment of any Imposition or other tax, assessment, levy or
charge, may be relied upon by Landlord as sufficient evidence that such
Imposition or other tax, assessment, levy or charge is due and unpaid at the
time of the making or issuance of such certificate, advice or bill. The Landlord
shall notify all taxing authorities to deliver tax bills, assessment, and/or
levies directly to Tenant during the Term, at the address provided by Tenant to
Landlord. Notwithstanding such notice to the taxing authorities, if any tax
bills, assessments or levies are nonetheless delivered to the Landlord, Landlord
shall promptly provide such documents to Tenant. Landlord shall be responsible
for any penalties and/or interest imposed by taxing authorities resulting from
the failure of the Landlord to promptly deliver to Tenant any bills, assessments
and/or levies that were delivered to Landlord (and not Tenant) by the applicable
taxing authority. For purposes of this Section 4.3, "promptly deliver" shall
mean Landlord's obligation to deliver to Tenant such tax bills, assessments
and/or levies within five (5) days of Landlord's receipt thereof, if such tax
bill, assessment and/or levy is payable 

                                       27
<PAGE>
 
within thirty (30) days or less from the date of Landlord's receipt thereof.

     SECTION 4.4    ADDITIONAL RENT ESCROW.  Should Tenant default in the timely
payment of any Imposition or other Additional Rent and thereafter fail to make
payment within fifteen (15) days of written demand by Landlord, at Landlord's
further written demand, Tenant shall pay to Landlord the known or estimated
yearly real estate taxes, assessments and Park Assessments payable with respect
to the Demised Premises, in monthly payments equal to one-twelfth (1/12) of the
known or estimated yearly real estate taxes, assessments and Park Assessments
next payable with respect to the Demised Premises. From time to time, Landlord
may re-estimate the amount of real estate taxes, assessments and Park
Assessments, and in such event, Landlord shall notify Tenant, in writing, of
such re-estimate and fix future monthly installments for the remaining period
prior to the next tax and assessment due date in an amount sufficient to pay the
re-estimated amount over the balance of such period, after giving credit for
payments made by Tenant on the previous estimate. If the total monthly payments
made by Tenant pursuant to this Section 4.5 shall exceed the amount of payments
necessary for said taxes and assessments, such excess shall be promptly paid to
Tenant, and the balance shall be credited on subsequent monthly payments of the
same nature. However, if the total of such monthly payments so made under this
Section 4.5 shall be insufficient to pay such taxes and assessments when due,
then Tenant shall immediately pay to Landlord such amount as may be necessary to
make up the deficiency. If under this Section 4.5, Tenant is making periodic
deposits of funds with Landlord for the purposes of paying taxes and assessments
as aforesaid, then Landlord covenants and agrees with Tenant that it will pay
all such taxes and assessments as they become due, to the extent possible out of
such deposits.

     SECTION 4.5    LANDLORD'S AND TENANT'S RIGHT TO CONTEST IMPOSITIONS. Tenant
shall have the right, at Tenant's expense, to contest the amount or validity, in
whole or in part, of any Impositions by appropriate proceedings conducted in the
name of the Landlord or in the name of Landlord and Tenant. Landlord shall
cooperate with Tenant in executing documents or other actions as may be required
for Tenant to pursue challenges to the Impositions. To the extent that the
Tenant achieves a reduction in the Imposition, Tenant shall have the sole right
to any refunds of amounts of such Impositions previously paid by the Tenant. In
the event that the Landlord recommends to the Tenant that Tenant contest an
Imposition, and the Tenant fails to notify the Landlord, within sixty (60) days
that Tenant intends to contest the Imposition as recommended by the Landlord,
then Landlord shall have the right, but not the obligation, to contest the
amount or validity, in whole or in part, of any Impositions by appropriate
proceedings conducted in the name of Landlord or in the name of Landlord and
Tenant. If Landlord elects to contest the amount or validity, in whole or in
part, of any Impositions, such contests by Landlord shall be at Landlord's
expense; provided, however, that if the amounts payable by Tenant for
Impositions are reduced (or if a proposed increase in such amounts is avoided or
reduced) by reason of Landlord's contest of Impositions, Tenant shall reimburse
Landlord for costs incurred by Landlord in contesting Impositions (including,
without limitation, reasonable attorneys' fees), but such reimbursements shall
not be in excess of the amount saved by Tenant by reason of Landlord's actions
in contesting such Impositions. Tenant shall reasonably cooperate with Landlord
in regard to any and all such contests.

     (a) Property Insurance.  Landlord, at Tenant's sole cost and expense (such
         ------------------                                                    
cost and expense being a part of Tenant's Additional Rent hereunder), shall
obtain and continuously maintain in full force and effect at all times during
the Term, policies of insurance covering all of the Improvements, which
insurance shall be for the benefit of Landlord and its Mortgagees, as the named
insureds, against (i) loss or damage by fire; (ii) loss or damage from such
other risks or hazards now or hereafter embraced by a "Special Cause of Loss"
form, including without limitation, windstorm, hail, explosion, vandalism, riot
and civil commotion, damage from vehicles and aircraft, smoke damage, water
damage and debris removal; (iii) loss from flood if the Demised Premises are in
a federally designated flood area; (iv) loss from earthquake (if appropriate);
and (v) loss or damage from such other risks or hazards of a similar or
dissimilar nature which are now or may hereafter be customarily insured against
with respect to improvements similar in construction, design, general location,
use and occupancy to the Demised Premises ("Property Insurance"). The Property
Insurance shall not be subject to a deductible less than One Thousand and
00/100ths Dollars ($1,000.00) or greater than Ten Thousand and 00/100ths Dollars
($10,000.00).

     At all times, the Property Insurance coverage shall be in an amount equal
to one hundred percent (100%) of the then "Full Replacement Cost" of the
Improvements (except from the peril of flood in the event the Demised Premises
is located in a flood zone as identified by PEMA, in which event flood insurance
will be provided as an actual cash value basis),and shall include a so-called
"Agreed Amount Endorsement." Full Replacement Cost shall be interpreted to mean
the cost of replacing the Improvements, without deduction for depreciation,
obsolescence, or wear and tear, and shall include a reasonable sum for
architectural and engineering fees connected with the restoration or replacement
of the Improvements in the event of damages thereto or destruction thereof. Full
Replacement Cost shall be determined from time to time (but not more often than
once every three years), at the request of Tenant, or of Landlord or its
Mortgagees, by an appraiser, engineer, architect or contractor designated by the
party requesting such determination and at Tenant's expense. No omission on the
part of Landlord or Tenant to request any such determination shall relieve
Tenant of any of its obligations under this Article 5, nor shall it relieve
Tenant of any of its obligations in this Lease. Promptly after the construction
of any Tenant Work or any New Work (which Tenant Work and New Work by definition
is included, among other things, in the Improvements), Tenant shall inform
Landlord in writing of the fair market value and the Full Replacement Cost
thereof.

     (b)  Commercial Liability Insurance.  Landlord, at Tenant's sole cost and
          ------------------------------                                      
expense (such cost and expense being a part of Tenant's Additional Rent
hereunder), shall obtain and continuously maintain in full force and effect at
all times during the Term, Commercial Liability insurance covering claims for
bodily injury, personal injury or property damage for any loss, liability or
damage on, about or relating to the Demised Premises, or any portion thereof,

insureds and Tenant as an additional insured.

     (c) Business Interruption Including Extra Expense (Loss of Rents and Extra
         ----------------------------------------------------------------------
Expense).

of Tenant's Additional Rent hereunder), shall obtain and continuously maintain,
in full force and effect, at all times during the Term, rental interruption
insurance, insuring against loss of all or any portion of the Rent due and
payable hereunder, for up to twelve (12) months ("Business Interruption
Insurance). Such policy shall name Landlord and its Mortgagees as insureds
thereunder. The Business Interruption Insurance limit shall include a reasonable
extra expense limited as determined by Landlord from time to time.

     (d)  Insurance Companies.  The Property Insurance, the Commercial Liability

Holding Rating" of A- or better and a financial rating class of X or better;
(ii) cite the interest of Landlord and its Mortgagees in standard mortgagee

provide for cancellation or material change thereto only upon at least thirty
(30) days' prior written notice to Landlord and its Mortgagees.

     (e)  Procurement by Tenant.  Landlord shall advise Tenant, annually and in
          ---------------------                                                
writing, of the cost, scope and carrier from whom Landlord proposes to procure
the insurance required of Landlord to be procured and maintained pursuant to
this Section 5.1. Within fifteen (15) days following Tenant's receipt of such
notice, Tenant may elect, by written notice to Landlord, to procure equal or
better coverage from an equal or better carrier, in each instance reasonably
acceptable to Landlord, provided, however, Landlord shall be the owner of such
coverage, regardless of whether the premiums therefor is paid directly by
Tenant. If Tenant fails to notify Landlord of such election within said fifteen

     (a)  Property Insurance.  Tenant shall maintain insurance coverage upon all
          ------------------

     (d)  Cancellation Notice. Each policy of insurance required of Tenant under
          -------------------

          ----------------------

     SECTION 5.4    WAIVER OF SUBROGATION.  Subject to this Section 5.4,
Landlord and Tenant each hereby waive any and every claim for recovery from the
other for any and all loss or damage to the Demised Premises or to the contents
thereof, which loss or damage is covered by the provisions of any property
insurance policy carried, or would have been covered by the provisions of any
property insurance policy required to be carried, by either party pursuant to
this Lease. Inasmuch as this mutual waiver will preclude (subject to this
Section 5.4) the assignment of any such claim by subrogation (or otherwise) to
an insurance company (or any other person), Landlord and Tenant each agree to
have such insurance policies properly endorsed, if necessary, to prevent the
invalidation of such insurance coverage by reason of such waiver. Anything in
this Section 5.4 to the contrary notwithstanding, if at any time during the Term
the waiver of subrogation clause required to be maintained by Landlord and
Tenant, respectively, is no longer available on terms which are commercially
reasonable, then Landlord and Tenant shall, in good faith, find a mutually
acceptable alternative to the benefits afforded each other as a result of such
mutual waiver of subrogation.

     SECTION 5.5    REQUIREMENTS IN EVENT OF LOSS.  In the event of loss or
damage to the Demised Premises or in the event of a claim in connection with the
injury or death of any person at the Demised Premises or by reason of operations
at the Demised Premises, Tenant shall (i) promptly notify Landlord thereof in
writing; (ii) prepare and present timely claims to the appropriate insurers on
behalf of Tenant, Landlord, Landlord's designated agent and the Mortgagee; and
(iii) adjust and settle such claim, provided, however, that if Tenant has failed
to settle such claims within six (6) months of the event of loss or damage,
injury or death, then, upon ten (10) days' prior written notice to Tenant,
Landlord, Landlord's designated agent and/or the Mortgagee shall have the right
to adjust and settle such claims. In the case of property damage claims
involving net insurance proceeds of more than Ten Thousand and 00/100ths Dollars
($10,000.00), no settlement shall be made without Landlord's written consent,
which will not be unreasonably withheld or delayed, and Landlord (and its
designated agent and/or the Mortgagee) shall be entitled, at Landlord's cost, to
participate in the adjustment process.

     SECTION 5.6    PROCEEDS, PAYMENT AND POLICY PROVISIONS.  The Property
Insurance and the Commercial Liability Insurance required by Section 5.1 hereof
shall provide that the proceeds thereof shall be jointly payable to Landlord, or
its Mortgagees, and shall be applied, if applicable, to the repair, replacement
or Restoration (as such term is defined in Section 11.1 hereof) of Landlord's
Improvements.


                                   ARTICLE 6

              USE, MAINTENANCE AND MANAGEMENT OF DEMISED PREMISES

     SECTION 6.1    PREMISES USE.  Tenant shall use and occupy the Demised
Premises as an office facility and any use related to Tenant's
telecommunications business and for customer services and retail sales of
telecommunications products, provided Tenant, at its sole cost and expense
obtains the necessary approvals so the same is permitted by and consistent with
all zoning and other applicable statutes, rules, orders ordinances,
requirements, regulations or laws and the Park covenants ("Premises Use"). The
Premises Use shall also include the right of Pennsylvania Cellular Telephone
Corp. or any company resulting from a merger of or into Pennsylvania Cellular
Telephone Corp. or any company to which Pennsylvania Cellular Telephone Corp.
assigned all or 

                                       32
<PAGE>
 
substantially all of its assets (including this Lease) to use and locate
switching equipment or transmission satellite dishes or towers in or about the
Demised Premises, provided the related telecommunications business and
installations is permitted by and consistent with all zoning and other
applicable statutes, rules, orders, ordinances, requirements, regulations or
laws and the Park covenants, and such installation(s) (i) are done at Tenant's
sole cost and expense in a good workmanlike manner without detriment to any
structural component of the Demised Premises, (ii) are maintained by Tenant in
good condition and repair, (iii) do not increase the scope of Landlord's Repairs
and Maintenance (as defined in Section 6.3 hereof), and (iv) do not void or make
voidable any warranties affecting the Demised Premises. Any permitted sublessee
or assignee of Tenant shall be permitted to use any such switching equipment or
transmission satellite dishes or towers installed by Pennsylvania Cellular
Telephone Corp. as above provided, but shall not be permitted, as part of the
Premises Use, to constructed any additional switching equipment or transmission
satellite dishes or towers, unless such sublessee or assignee is a company
resulting from a merger of Pennsylvania Cellular Telephone Corp. as aforesaid or
is an assignee of all or substantially all of the assets (including this Lease)
of Pennsylvania Cellular Telephone Corp. Notwithstanding the foregoing, Tenant
shall not use or occupy the Demised Premises, or knowingly permit them to be
used or occupied, contrary to any statute, rule, order, ordinance, requirement
or regulation applicable thereto, or in any manner which would violate any
certificate of occupancy affecting the same, or which would make void or
voidable any insurance then in force with respect thereto or which would make it
impossible to obtain fire or other insurance thereon required to be furnished
hereunder by Landlord or Tenant, or which would cause structural injury to the
Improvements or cause the value or usefulness of the Demised Premises, or any
portion thereof, to diminish substantially, or which would constitute a public
or private nuisance or waste. Tenant shall promptly, upon discovery of any such
use, compel the discontinuance of such use.

     Tenant shall not use, suffer or permit the Demised Premises, or any portion
thereof, to be used by Tenant, any third party or the public (as such), without
restriction or in such manner as might reasonably tend to impair Landlord's
title to the Demised Premises, or in such manner as might reasonably make
possible a claim or claims of adverse usage or adverse possession by the public
(as such), or third persons, or of implied dedication of the Demised Premises,
or any portion thereof. Nothing contained in this Lease and no action or
inaction by Landlord shall be deemed or construed to mean that Landlord has
granted to Tenant any right, power or permission to do any act or make any
agreement that may create, or give rise to or be the foundation for any such
right, title, interest, lien, charge or other encumbrance upon the estate of
Landlord in the Demised Premises.

     SECTION 6.2    TENANT'S REPAIRS, MAINTENANCE AND REPLACEMENTS.  Except for
the obligations of the Landlord as expressly provided in Section 6.3 hereof,
Tenant, at its sole cost and expense, throughout the Term, shall keep in good
order, condition and repair, and shall make and perform all routine maintenance
and necessary repairs, ordinary and extraordinary, foreseen and unforeseen, of
every nature, kind and description shall take good care of the Demised Premises
and shall keep the same in good order, condition and repair, and shall make and
perform all routine maintenance thereof and all necessary repairs thereto,
ordinary and extraordinary, foreseen and unforeseen, of every nature, kind and
description. When used in this Article 6 "repairs" shall specifically include,
without limitation, all necessary replacements, renewals and alterations. All
repairs made by Tenant, except as hereinafter provided, shall be at least equal
in quality to the original work and, in all events, shall be made by Tenant in
Compliance with Laws. The necessity for or adequacy of maintenance and repairs
shall be measured by the standards which are 

                                       33
<PAGE>
 
appropriate for improvements of similar construction and class; provided,
however, that in all events, Tenant shall make all repairs necessary to avoid
any structural damage or other damage or injury to the Improvements.

     In addition, except for the obligations of the Landlord provided in Section
6.3, herein, Tenant shall timely and properly repair and maintain all of the
Demised Premises, including, without limitation, electrical systems, plumbing
systems, heating, ventilating and air conditioning systems, fire protection
systems, other mechanical systems, and landscaping, in accordance with the
highest of the following standards: (a) the manufacturer's recommended
maintenance schedule which is necessary so as not to void, diminish or impair
any warranty for such item from time to time in effect; or (b) that which is
generally recognized as the industry standard for the required maintenance and
repair of each such item. Tenant shall also keep all portions of the Demised
Premises in a clean and orderly condition, free of snow, ice, dirt, rubbish,
debris and unlawful obstructions. All of Tenant's obligations and requirements
described in this Section 6.2 are herein collectively referred to as "Tenant's
Repairs and Maintenance." The time permitted for Tenant to effectuate Tenant's
Repairs and Maintenance shall be extended for such period as may reasonably be
necessary; provided, however, that Tenant shall continuously, diligently and in
good faith prosecute the same. In addition, Landlord, not more frequently than
annually during the Term, upon five (5) days written notice (except in the event
of an emergency or extraordinary condition), may cause, at Landlord's sole cost
and expense, independent private building inspectors, qualified in the specific
discipline, to make inspections of the Demised Premises, and the systems or
segments thereof, to determine Tenant's compliance under this Section 6.2.

     If Tenant does not timely or properly perform Tenant's Repairs and
Maintenance as herein provided, Landlord may, but need not, after thirty (30)
days' notice to Tenant, make such repairs, replacements or maintenance in a
reasonably diligent fashion. Tenant shall pay to Landlord all of Landlord's
actual costs incurred in connection therewith, plus a fee of ten percent (10%)
of such cost, forthwith upon being billed therefor. Landlord may, but shall not
be required to, enter the Demised Premises at all reasonable times upon
reasonable notice (except in the instance of an emergency) to make such repairs,
alterations, improvements and additions to the Demised Premises or to any
equipment, fixtures or landscaping located on the Demised Premises, as Landlord
deems reasonably necessary and which Tenant failed to do as required in this
Lease after written notice from Landlord. However, any and all repairs,
replacements or maintenance made by Landlord pursuant to this Lease shall be
done in a reasonably diligent manner and so as to minimize any disruption to
Tenant's business operations.

     SECTION 6.3    LANDLORD'S REPAIRS, MAINTENANCE AND REPLACEMENTS.  Landlord,
at its sole cost and expense, throughout the Term, shall (i) keep in good order,
condition and repair, and shall make and perform all routine maintenance and
necessary repairs and replacements, ordinary and extraordinary, foreseen and
unforeseen, of every nature, kind and description, to the roof, floor slabs,
foundation walls and footings, structural steel, exterior walls, driveways,
roadways, sidewalks, curbs, parking areas, and loading areas (including, in the
instance of driveways, roadways, sidewalks, parking areas, and loading areas,
repaving and striping the same, as applicable) forming a part of Landlord's
Improvements, and (ii) make all Capital Replacements (as defined in Section 6.7)
of all or any portion of the heating, ventilating and air conditioning,
electrical, plumbing, fire protection and other mechanical systems forming a
part of Landlord's Improvements (collectively, in respect to clause (i) and (ii)
above, "Landlord's Repairs and 

                                       34
<PAGE>
 
Maintenance"). Because Landlord shall not have any regular on-site presence at
the Demised Premises, Tenant agrees to timely advise Landlord, in writing, of
any Landlord's Repairs and Maintenance Tenant reasonably believes Landlord must
undertake.

     SECTION 6.4    PROHIBITION AGAINST WASTE.  Tenant shall not do or suffer
any waste or damage, disfigurement or injury to the Demised Premises (including,
without limitation, any and all improvements now or hereafter erected thereon,
and any and all fixtures or equipment now or hereafter located therein), or
permit or suffer any overloading of the floors or other use of the Improvements
that would place an undue stress on the same or any portion thereof beyond that
for which the same was designed.

     SECTION 6.5    MISUSE OR NEGLECT.  Anything in this Lease to the contrary
notwithstanding, Tenant shall be responsible for all repairs to the Demised
Premises which are made necessary by any misuse or neglect by Tenant, or any of
its partners, directors, officers, shareholders, contractors, subcontractors,
sub-subcontractors, employees, agents or invitees, in or upon the Demised
Premises. Notwithstanding anything to the contrary contained in Section 6.3
hereof or elsewhere in this Lease, Landlord's Repairs and Maintenance shall not
impose any duty on the Landlord in respect to those Landlord's Improvements that
are the subject of Landlord's Repairs and Maintenance that are (a) damaged or
destroyed by the misuse or intentional acts of Tenant or any of its partners,
directors, officers, shareholders, contractors, subcontractors, sub-
subcontractors, employees, agents or invitees, in or upon the Demised Premises,
or (b) in disrepair or are damaged as a result of Tenant's failure to timely and
properly perform Tenant's Repairs and Maintenance.

     SECTION 6.6    MANAGEMENT OF DEMISED PREMISES.

          (A)  Anything in this Lease to the contrary notwithstanding, Landlord
shall perform, or shall cause to be performed, all of Landlord's obligations
under this Lease in connection with Landlord's Repairs and Maintenance by an
independent third party property manager in a manner consistent with the first-
class standards of commercial property managers in the geographic area in which
the Demised Premises are located ("Landlord's Manager"). As of the Delivery
Date, Landlord's Manager shall be a property management entity with offices
locally in the Harrisburg area. Notwithstanding the foregoing, in the event any
successor Landlord determines that such local Landlord's Manager is not
performing Landlord's Repairs and Maintenance in to the standards required by
this Lease or at a commercially reasonable cost, such successor Landlord shall
be permitted to terminate such local Landlord's Manager and replace the same
with any other property management entity (regardless of whether located locally
in this Harrisburg area) that is reasonably acceptable to Tenant. During the
Term, Tenant shall pay to Landlord, as part of the Additional Rent, (i) a
monthly fee equal to the actual out-of-pocket cost to Landlord paid to the
Landlord's Manager, but in no instance and amount greater than one and one
quarter percent (1.25 %) of the monthly Base Rent required by Tenant to be paid
at the subject time during the Term ("Management Fee").

          In the event that, at any time during the Term, Tenant reasonably
determines that Landlord has failed to properly perform Landlord's Repairs and
Maintenance, then Tenant shall give the Landlord written notice thereof setting
forth, with reasonable specificity, the type and nature of the subject
deficiencies. Following the receipt of such notice of deficiency, Landlord shall

                                       35
<PAGE>
 
have a period of thirty (30) days in which to cure such noticed deficiencies and
advise Tenant of the actions taken by Landlord to cure the same, provided,
however, if a deficiency is not susceptible to cure within such thirty (30)
period, Landlord shall nonetheless be deemed curing, if Landlord commences such
cure within said thirty (30) day period and thereafter diligently prosecutes the
same to completion. If the Landlord fails to take reasonable actions to cure the
noticed deficiencies, then Tenant shall have the right to direct Landlord to
terminate the Landlord's Manager and replace it with a substitute Landlord's
Manager reasonably acceptable to Tenant.

     During the Term, Tenant shall be permitted to retain, at Tenant's sole cost
and expense, such other property management entity Tenant reasonably chooses to
perform Tenant's Repairs and Maintenance and/or any of Tenant's other
performance obligations under the terms of this Lease.


          (b)  Landlord shall maintain or cause the Landlord's Manager to
maintain a temperature range for all office areas within the Demised Premises
between 68 Fahrenheit and 76 Fahrenheit and FDB relative humidity at a level of
not greater than fifty percent (50%) from 7:00 A.M. to 7:00 P.M. (Saturdays 8:00
A.M. to 1:00 P.M.), Sundays and holidays excepted, and shall maintain the air
quality within the Demised Premises within ASHRAE standards. Notwithstanding the
foregoing, Landlord shall not be responsible for such standards during
emergencies or when a Tenant's or Landlord's Repairs and Maintenance is being
undertaken that, in either instance, affect the heating, ventilating and air
condition systems of the Demised Premises. A reasonable period of time at the
beginning of the heating and cooling season shall be allocated for adjustments
to the HVAC system by Landlord. The relocation of Tenant's personnel within the
Demised Premises (or a change in use of any area of the Demised Premises,
provided it is nonetheless a Permitted Use) shall not diminish Landlord's
obligation to meet the temperature, humidity, and air quality standards
hereunder, so long as a reasonable period of time is afforded to the Landlord
after notice from the Tenant for the Landlord to adjust or modify the HVAC
system as may be necessary to accommodate such relocation or change in use.

     SECTION 6.7 CAPITAL REPLACEMENT. "Capital Replacement," for purposes of
this Lease, shall mean the replacement of a capital item (as defined in the
United States Internal Revenue Code, 1984, as amended) comprising a part of
Landlord's Improvements having a cost in excess of $5,000.00, which $5,000.00
amount shall be increased over the Term by the percentage by which the CPI Index
published nearest to the expiration of each twelve (12) month period subsequent
to the Initial Term Commencement Date is greater than the CPI Index most
recently published prior to the Initial Term Commencement Date

                                   ARTICLE 7

removal of any such violation and the costs and expenses necessitated thereby
shall have been foreseen or unforeseen, ordinary or extraordinary, and whether
the same shall be presently within the contemplation of Landlord or Tenant or
shall involve any change of governmental policy, or require structural or
extraordinary repairs, alterations or additions by Tenant and irrespective of
the costs thereof ("Compliance with Laws"). Regardless of the foregoing
provisions, Tenant's obligations with regard to Compliance with Laws shall not
extend to any compliance with or removal or cure of any violation of any laws,
ordinances, zoning or otherwise, orders, rules, regulations and requirements of
federal, state, municipal or governmental bodies which results from the
construction of the Demised Premises or other circumstances, facts, conditions
or events which occurred or were in existence as of or prior to the Initial
Commencement Date.

     SECTION 7.2 OTHER COMPLIANCE. Tenant, at its sole cost and expense, shall

Premises and required to be obtained and maintained under the terms of Article 5
hereof, and shall comply with all development permits issued by governmental
authorities issued in connection with development of the Demised Premises.

and shall otherwise evidence Tenant's compliance with this Article 7.  If

     SECTION 8.1 LIENS AND RIGHT OF CONTEST.  Tenant shall not suffer or permit
any mechanic's lien or other lien to be filed against the Demised Premises, or
any portion thereof, by reason of work, labor, skill, services, equipment or
materials supplied or claimed to have been supplied to the Demised Premises at
the request of Tenant, or anyone holding the Demised Premises, or any portion
thereof, by, through or under Tenant.  If any such mechanic's lien or other lien
shall at any time be filed against the Demised Premises, or any portion thereof,
Tenant shall cause the same to be 

                                       40
<PAGE>
 
discharged of record within thirty (30) days after the date of filing the same.
However, in the event Tenant desires to contest the validity of any lien, it
shall (a) on or before thirty (30) days prior to the due date thereof, notify
Landlord, in writing, that Tenant intends so to contest the same, and (b) on or
before the due date thereof, if Landlord reasonably deems Tenant to be
financially insecure or if any Mortgagee of Landlord so requires, deposit with
Landlord security (in form and content reasonably satisfactory to Landlord or
Landlord's Mortgagees) for the payment of the full amount of such lien and, from
time to time, deposit additional security or indemnity so that, at all times,
adequate security or indemnity will be available for the payment of the full
amount of the lien together with all interest, penalties, costs and charges
accrued or accumulated thereon.

     If Tenant complies with the foregoing, and Tenant continues, in good faith,
to contest the validity of such lien by appropriate legal proceedings which
shall operate to prevent the collection thereof and the sale or forfeiture of
the Demised Premises, or any part thereof, to satisfy the same, Tenant shall be
under no obligation to pay such lien until such time as the same has been
decreed, by court order, to be a valid lien on the Demised Premises. Any surplus
deposit retained by Landlord, after the payment of the lien shall be repaid to
Tenant. Provided that nonpayment of such lien does not cause Landlord to be in
violation of any of its contractual undertakings, Landlord agrees not to pay
such lien during the period of Tenant's contest. However, if Landlord pays for
the discharge of a lien or any part thereof from funds of Landlord, any amount
paid by Landlord, together with all costs, fees and expenses in connection
therewith (including, without limitation, reasonable attorneys' fees of
Landlord), together with interest thereon at the Maximum Rate of Interest, shall
be repaid by Tenant to Landlord on demand by Landlord. Tenant shall indemnify
and save Landlord, and its partners, directors, officers, shareholders,
contractors, subcontractors, sub-subcontractors, Mortgagees, agents and
employees, and the Demised Premises, harmless from and against any and all loss,
cost or damage, including, without limitation, reasonable attorneys' fees,
incurred or sustained by any of them in connection with the assertion, filing,
foreclosure or other legal proceedings with respect to any such mechanic's lien
or other lien or the attempt by Tenant to discharge the same as above provided.

     All materialmen, contractors, artisans, mechanics, laborers and any other
person now or hereafter furnishing any labor, services, materials, supplies or
equipment to Tenant with respect to the Demised Premises, or any portion
thereof, are hereby charged with notice that they must look exclusively to
Tenant to obtain payment for the same. Notice is hereby given that Landlord
shall not be liable for any labor, services, materials, supplies, skill,
machinery, fixtures or equipment furnished or to be furnished to Tenant upon
credit, and that no mechanic's lien or other lien for any such labor, services,
materials, supplies, machinery, fixtures or equipment shall attach to or affect
the estate or interest of Landlord in and to the Demised Premises, or any
portion thereof.

     SECTION 8.2 LIENS ON LANDLORD'S AND CONTRACTOR'S WORK. The provisions of
Section 8.1 hereof shall not apply to any mechanic's lien or other lien for
labor, services, materials, supplies, machinery, fixtures or equipment furnished
to the Demised Premises in the performance of Landlord's or Contractor's
obligations to construct Landlord's Improvements, or to provide Warranty Work or
Punch List Item work required herein. Landlord shall indemnify and save Tenant,
and its partners, directors, officers, shareholders, contractors,
subcontractors, sub-subcontractors, agents and employees, harmless from and
against any and all direct (but not indirect or consequential) loss, cost or
damage, including, without limitation, reasonable attorneys' fees, incurred or
sustained by any of them in connection with the assertion, filing, foreclosure
or other

                                       41
<PAGE>
 
legal proceedings with respect to any such mechanic's lien or other lien.
Landlord shall cause the Contractor to enter into and duly record a waiver of
mechanics' liens pursuant to a Pennsylvania Mechanics' Lien law in such form and
substance, so as to result in an effective waiver of mechanics' liens pursuant
to said law.

     SECTION 8.3 OTHER LIENS. Tenant shall not create, permit or suffer, and,
subject to the provisions of Section 8.1 hereof, shall promptly discharge and
satisfy of record, any other lien, encumbrance, charge, security interest, or
other right or interest which, as a result of Tenant's action or inaction
contrary to the provisions hereof, shall be or become a lien, encumbrance,
charge or security interest upon the Demised Premises, or any portion thereof,
or the income therefrom.

eminent domain or like proceedings.

to Tenant (or without notice in case of emergency), and without waiving or
releasing Tenant from any obligation of Tenant contained in this Lease, may, but
shall be under no obligation to do so, (a) pay after such fifteen (15) days'
written notice to Tenant, any such Additional Rent payable by Tenant pursuant to
the provisions hereof; or (b) make any other payment or perform any other act on
Tenant's part to be paid or performed hereunder, except that any time permitted
to Tenant to perform any act required to be performed by Tenant hereunder shall
be extended for such period as may be necessary to effectuate such performance,
provided Tenant is continuously, diligently and in good faith prosecuting such
performance. Landlord may enter upon the Demised Premises for any such purpose
and take all such action therein or thereon as may be necessary therefor and all
such action taken by Landlord shall be in a reasonably diligent fashion.

     SECTION 9.3 PAYMENT FOR LANDLORD'S PERFORMANCE FOR TENANT. All sums so paid
by Landlord and all costs and expenses, including, without limitation,
reasonable attorneys' fees, incurred by Landlord in connection with the
performance of any such act, together with interest thereon at the Maximum Rate
of Interest from the respective dates of Landlord's making of each payment of
such cost and expense, shall be paid by Tenant to Landlord on demand.

may claim against Tenant arising out of or by reason of Tenant's failure to
provide and keep in force insurance as aforesaid, to the amount of the insurance
premium or premiums not paid or not incurred by Tenant, and which would have
been payable upon such insurance.  Rather, Landlord shall also be

actually carried by Tenant), damages, costs and expenses of suit, including,
without limitation, reasonable attorneys' fees, suffered or incurred by reason
of damage to or destruction of the Demised Premises, or any portion thereof, or
other damage or loss which Tenant is required to insure against hereunder,
occurring during any period when Tenant shall have failed or neglected to
provide insurance as aforesaid.

                       DEFAULTS AND LANDLORD'S REMEDIES

     SECTION 10.1 DEFAULT. The following events, after the expiration of the
applicable cure periods in this Article 10 (except as otherwise provided in this
Lease), are sometimes referred to as an event of "Default":

     (a)  If default shall be made by Tenant under the provisions of Article 13
          hereof relating to assignment, sublease, mortgage or other transfer of
          Tenant's interest in this Lease or in the Demised Premises or in the
          income arising therefrom;

     (b)  If default shall be made in the due and punctual payment of Base Rent
          or any installment thereof, or if default shall be made in the payment
          of Additional Rent or in the payment of any other sum required to be
          paid by Tenant under this Lease, after five (5) days' written notice,
          except that Tenant shall be permitted, not more than once each
          calendar year during the Term, to be late by not more than ten (10)
          days in the payment of any installment of Base Rent or Additional Rent
          hereunder before Landlord shall be permitted to declare a Default by
          Tenant;

     (c)  If default shall be made in the observance or performance of any of
          the other covenants or conditions in this Lease which Tenant is
          required to observe and perform, and such default shall continue for
          thirty (30) days after written notice to Tenant, or if a default
          involves a hazardous or emergency condition and is not cured by Tenant
          immediately, provided, however, that the time allowed Tenant (except
          in the instance of hazardous or emergency conditions) within which
          Tenant is permitted to cure the same shall be extended for such
          reasonable period as may be necessary for the curing, provided Tenant
          is continuously, diligently and in good faith prosecuting such cure;
          and

     (d)  If, during the Term, (i) Tenant shall make an assignment for the
          benefit of creditors, (ii) a voluntary petition shall be filed by
          Tenant under any law having for its purpose the adjudication of Tenant
          a bankrupt, or Tenant shall be adjudged a bankrupt pursuant to an
          involuntary petition in bankruptcy, (iii) a receiver shall be
          appointed for the property of Tenant, or (iv) any

                                       43

          department of the state or federal government, or any officer thereof
          duly authorized, shall take possession of the business or property of
          Tenant, Landlord may treat the occurrence of any one or more of the
          foregoing events of Default as a breach of this Lease.

     In any such event, Landlord, at any time thereafter during the continuance
of any such event of Default, may give written notice to Tenant specifying such
event of Default or events of Default and stating that this Lease and the Term
hereby demised shall expire and terminate on the date specified in such notice,
and upon the date specified in such notice, this Lease and the Term hereby
demised, and all rights of Tenant under this Lease, including, without
limitation, all rights of renewal whether exercised or not, shall expire and
terminate, or in the alternative or in addition to the foregoing remedy,
Landlord may assert and have the benefit of any and all other remedies and
rights provided at law or in equity.

     SECTION 10.2  RENT AFTER DEFAULT. In the event of an uncured Default,
Landlord may terminate this Lease and the Term created hereby, in which event
Landlord may forthwith repossess the Demised Premises and be entitled to recover
as damages, in addition to any other sums or damages for which Tenant may be
liable to Landlord hereunder, a sum of money equal to the excess of the value of
the Rent provided to be paid by Tenant for the balance of the Term over the fair
market rental value of the Demised Premises, after deduction of all anticipated
expenses of re-letting for said period, and discounting the amount to a present
value using an interest rate equal to the prime rate of interest published in
the Wall Street Journal at the time such present value is determined, but if
    -------------------                                                     
such rate of interest shall exceed the highest rate allowed by law, such rate
shall be reduced to the highest rate allowed by law.  Should the fair market
rental value of the Demised Premises, after deduction of all anticipated
expenses of re-letting, for the balance of the Term, exceed the value of the
Rent provided to be paid by Tenant for the balance of the Term, Landlord shall
have no obligation to pay Tenant the excess or any part thereof, or to credit
such excess or any part thereof against any other sums or damages for which
Tenant may be liable to Landlord.

     SECTION 10.3  RE-LETTING AFTER DEFAULT. To the extent permitted by law,
in the event of a Default, Landlord may terminate Tenant's right of possession
and may repossess the Demised Premises by forcible entry and detainer suit, by
taking peaceful possession or otherwise, without terminating this Lease. In such
event, Landlord shall use good faith efforts to relet the same for the account
of Tenant, for such rent and upon such terms as may be satisfactory to Landlord.
For the purpose of such re-letting, Landlord is authorized to repair, remodel or
alter the Demised Premises. If Landlord shall fail to relet the Demised
Premises, Tenant shall pay to Landlord, as damages, a sum equal to the amount of
Rent reserved in this Lease for the balance of the Initial Term or the Renewal
Term, as the case may be, as the same becomes due and payable. If the Demised
Premises are relet and a sufficient sum shall not be realized from such re-
letting, after paying all of the costs and expenses of all decoration, repairs,
remodeling, alterations and additions and the expenses of such re-letting and of
the collection of the rent accruing therefrom, to satisfy the Rent provided for
in this Lease, Tenant shall satisfy and pay the same upon demand therefor from
time to time. Tenant agrees that Landlord may file suit to recover any sums
failing due under the terms of this Article 10 from time to time, and that no
suit or recovery of any portion due to Landlord hereunder shall be any defense
to any subsequent action brought for any amount not theretofore reduced to
judgment in favor of Landlord.

                                       44
<PAGE>
 
     SECTION 10.4 ACCEPTANCE AFTER DEFAULT; NO WAIVER. No failure by Landlord or
Tenant, as the case may be, to insist upon the performance of any of the terms
of this Lease or to exercise any right or remedy consequent upon a breach
thereof, and no acceptance by Landlord of full or partial Rent from Tenant or
any third party during the continuance of any such breach, shall constitute a
waiver of any such breach or of any of the terms of this Lease. None of the
terms of this Lease to be kept, observed or performed by either party hereunder,
and no breach thereof, shall be waived, altered or modified except by a written
instrument executed by both Landlord and Tenant. No waiver of any breach shall
affect or alter this Lease, but each of the terms of this Lease shall continue
in full force and effect with respect to any other then existing or subsequent
breach of this Lease. No waiver of any Default of Tenant herein shall be implied
from any omission by Landlord to take any action on account of such Default. If
such Default persists or is repeated, no express waiver shall affect any Default
other than the Default specified in the express waiver, and then only for the
time and to the extent therein stated. One or more waivers by Landlord or by
Tenant, as the case may be, shall not be construed as a waiver of a subsequent
breach of the same covenant, term or condition.

     SECTION 10.5 REMEDIES CUMULATIVE. Upon a default by Tenant of any of the
terms contained in this Lease, Landlord shall be entitled to invoke any right or
remedy allowed at law or in equity or by statute or otherwise as though entry,
reentry, summary proceedings and other remedies, as the case may be, were not
provided for in this Lease. Each remedy or right of Landlord provided for in
this Lease shall be cumulative and shall be in addition to every other right or
remedy provided for in this Lease, or now or hereafter existing at law or in
equity or by statute or otherwise. The exercise or the beginning of the exercise
by Landlord of any one or more of such rights or remedies, except as otherwise
provided herein, shall not preclude the simultaneous or later exercise by
Landlord of any or all other rights or remedies.

     SECTION 10.6 LANDLORD DEFAULT. Subject to Section 14.2 hereof, if at any
time during the Term, Landlord has failed to perform any of its limited
obligations under this Lease, then Tenant shall provide written notice of such
default to Landlord. If, within thirty (30) days after Landlord's receipt of
Tenant's notice (or such shorter time as is reasonable, in the case of an
emergency), Landlord has not cured such default, or has not commenced and
diligently pursued the cure thereof, then Tenant shall provide an additional
written notice to Landlord. Then, if Landlord does not cure such default, or
does not commence and diligently pursue such cure, within ten (10) days (or such
shorter time as is reasonable, in the case of an emergency) after Landlord's
receipt of such additional notice, then Tenant may, in Tenant's sole discretion
take such steps to cure such default as may be reasonably required. Landlord
shall reimburse Tenant for the reasonable costs and expenses of such cure,
including reasonable attorneys fees, with interest at the Maximum Rate of
Interest from the date of the invoices to the date of payment by Landlord, and a
ten percent (10%) administrative fee within thirty (30) days after Tenant has
provided Landlord with a written statement thereof, together with reasonable
supporting documentation. However, anything in this Section 10.6 or elsewhere in
this Lease to the contrary notwithstanding, no actions taken by Tenant to cure
any default of Landlord under this Lease shall ever be deemed (a) to constitute
an eviction or disturbance of Tenant's use and possession of the Demised
Premises, (b) to relieve Tenant from any of its obligations to pay Rent when
due, without abatement (except as otherwise expressly provided in this Lease),
or (c) to perform any of Tenant's other obligations under this Lease.

                          DESTRUCTION AND RESTORATION

     SECTION 11.1 RESTORATION. In the event of any damage to or destruction of
Landlord's Improvements, upon the occurrence thereof, Tenant shall forthwith
give Landlord written notice (except in cases of emergency when Landlord may be
notified by telephone, with a written notification to follow promptly) of such
damage or destruction, and shall specify in such notice, in reasonable detail,
the extent thereof. If any such damage or destruction occurs, the restoration,
repair, replacement, rebuilding (including, without limitation, the cost of
temporary repairs) of Landlord's Improvements or any portion thereof to the
condition (as is reasonably practical) existing immediately prior to such damage
or destruction are sometimes hereinafter referred to as the "Restoration." In
all instance of Restoration, Landlord shall employ its diligent efforts to
reasonably promptly complete the Restoration required of it with as little
disruption of the Premises Use as is reasonably practicable.

     Except as hereafter provided, in case of damage to or destruction of all or
a portion of Landlord's Improvements by fire or otherwise during the Term,
Landlord, at the cost and expense hereafter provided, shall, within sixty (60)
days after the date of the damage or destruction, commence and thereafter
diligently complete the Restoration for which the Property Insurance set forth
in Section 5.1 hereof was procured. Notwithstanding the foregoing, Landlord
shall not be obligated to undertake the Restoration in the event any such damage
or destruction (i) occurs at any time during the last twelve (12) months of the
then current Term (including any renewals hereunder), or (ii) is of such a
degree that no reasonable portion of Landlord's Improvements can be occupied for
the Premises Uses and the damage or destruction occurs at such a time of the
year, taking into account seasonal weather conditions, that the Restoration
cannot be reasonably completed within three hundred and sixty-five (365) days.
In any of the foregoing instances, Landlord shall provide Tenant with notice,
within forty-five (45) days of such damage or destruction, of Landlord's
decision whether Landlord will undertake the Restoration. If Landlord has failed
to deliver the foregoing notice, it shall be conclusively presumed that Landlord
has elected to undertake the Restoration. If Landlord has elected, as aforesaid,
not to undertake the Restoration, then Tenant may terminate this Lease by
providing Landlord with notice thereof within fifteen (15) days of the notice
from Landlord.

     Regardless of the foregoing, in the instance of any destruction of
Landlord's Improvements in respect to which Landlord has elected (or is deemed
to have elected, as aforesaid) to undertake the Restoration, Tenant may
nonetheless terminate this Lease, if Landlord does not commence the Restoration
within sixty (60) days after the date of such destruction. For purposes of this
Section 11.1, Landlord shall be deemed to have "commenced" the Restoration, if
Landlord has commissioned the preparation of plans and specifications necessary
for such Restoration or undertaken other meaningful measures necessary, in a
commercially reasonable context, to effectuate such Restoration. If Landlord
commences the Restoration more than sixty (60) days after the subject
destruction, and Tenant has not yet then delivered to Landlord Tenant's notice
of termination of this Lease, Tenant shall be deemed to have waived the
immediately foregoing right of termination on the date Landlord commenced the
subject Restoration. If the Restoration is

                                       46
<PAGE>
 
commenced, Tenant may nonetheless thereafter elect to terminate this Lease, if,
(i) in the instance of a complete destruction of Landlord's Improvements
resulting in the inability of Tenant to reasonably occupy any of the Landlord's
Improvements for the Premises Uses, Landlord does not complete the Restoration
within three hundred sixty-five (365) days after the date of such destruction,
or (ii) in the instance of a partial destruction of Landlord's Improvements
resulting in Tenant being able to continue to reasonably occupy a material
portion of Landlord's Improvements for the Premises Uses, Landlord does not
complete the Restoration within two hundred seventy (270) days after the date of
such destruction.

     If Landlord's Improvements are damaged or destroyed so that no portion
thereof can be reasonably occupied for the Premises Uses, the Base Rent and
Additional Rent shall abate as of the date of the damage until the Restoration
is complete and an occupancy permit and all other permits and approvals are
issued such that the Tenant can reoccupy the Demised Premises. If the damage or
destruction is or such a degree so that Tenant can continue to use the Demised
Premises in a manner that permits the Tenant to continue to conduct its business
operations in a useful and efficient manner, as determined in the reasonable
discretion of the Tenant, then the Base Rent and Additional Rent shall be fairly
and equitably reduced to reflect the limited use of the Demised Premises by the
Tenant until the Restoration is complete as aforesaid.

     SECTION 11.2 INSURANCE PROCEEDS. All insurance moneys recovered by Landlord
on account of such damage or destruction, less the costs, if any, to Landlord of
such recovery, shall be applied by Landlord to the payment of the costs of the
Restoration and shall be paid out from time to time as the Restoration
progresses. If the net amount of the insurance proceeds (after deduction of all
costs, expenses and fees (including, without limitation, attorneys' fees)
related to recovery of the insurance proceeds) recovered by Landlord is
insufficient to complete the Restoration (exclusive of Tenant's personal
property and Tenant's Trade Fixtures, all of which shall be restored, repaired
or rebuilt out of Tenant's separate funds), Landlord shall pay, any deficiency
necessary to cause the completion of Restoration. In all events, the full amount
of any deductible under the applicable insurance policies shall be paid by
Tenant within thirty (30) days after Landlord's invoice therefor.

     SECTION 11.3 CONTINUANCE OF TENANT'S OBLIGATIONS. Regardless of the
foregoing provision of Sections 11.1 and 11.2, Tenant shall not be liable for
Rent in the event of damage or destruction of the Demised Premises, to the
extent (if any) that such Rent obligations of Tenant are paid by Landlord's
receipt of proceeds under any Business Interruption Insurance.


                                  ARTICLE 12
                                 CONDEMNATION

     SECTION 12.1 TOTAL CONDEMNATION. If during the Term, the entire Demised
Premises shall be taken as the result of the exercise of the power of eminent
domain ("Proceedings"), this Lease and all right, title and interest of Tenant
hereunder shall terminate on the date of vesting of title pursuant to such
Proceedings, and Landlord shall be entitled to and shall receive the total award
made in such Proceedings. Tenant hereby assigns any interest in such award,
damages, consequential damages and compensation to Landlord. Landlord agrees
that it will not object to the petition of Tenant for a separate award as set
forth herein; provided, however, that any such petition or award shall in no way
diminish the award otherwise payable to Landlord hereunder.

                                       47
<PAGE>
 
     SECTION 12.2 PARTIAL CONDEMNATION. If during the Term, less than the entire
Demised Premises shall be taken in any such Proceedings, then this Lease shall,
upon vesting of title in the Proceedings, terminate as to the portion of the
Demised Premises so taken. If the portion of the Demised Premises taken shall
substantially and materially interfere with or inhibit Tenant's Premises Use of
the Demised Premises, Tenant may, at its option, terminate this Lease as to the
remainder of the Demised Premises. Tenant shall not have the right to terminate
this Lease pursuant to the preceding sentence, however, if that portion of the
Demised Premises not taken can reasonably be utilized by Tenant with
substantially the same utility and efficiency as prior to the taking. Such
termination as to the remainder of the Demised Premises shall be effected by
Tenant's written notice to Landlord, given not more than sixty (60) days after
the date of vesting of title in such Proceedings, and shall specify a date not
more than sixty (60) days after the giving of such notice as the date for such
termination. Upon the date specified in such notice and Landlord's determination
as aforesaid, the Term, and all right, title and interest of Tenant hereunder,
shall cease and terminate. If this Lease is terminated as provided in this
Section 12.2, Landlord shall receive the award as is provided in Section 12.1
hereof. In the event that Tenant elects not to terminate this Lease as to the
remainder of the Demised Premises, the rights and obligations of Landlord and
Tenant shall be governed by the provisions of Section 12.3 hereof.

     SECTION 12.3 RESTORATION AFTER CONDEMNATION. If, in the case of a partial
taking, this Lease is not terminated as provided in Section 12.2 hereof, this
Lease shall, upon vesting of title pursuant to the Proceedings, terminate as to
the parts so taken, and, except as provided in Section 12.1 hereof, Tenant shall
have no claim or interest in the award, damages, consequential damages and
compensation, or any part thereof. Landlord, in such case, covenants and agrees
promptly to restore that portion of the Demised Premises not so taken to a
complete architectural and mechanical unit for Tenant's Premises Uses as
provided in this Lease. In the event that the net amount of the award (after
deduction of all costs and expenses, including, without limitation, attorneys'
fees) that may be received by Landlord in any such Proceedings as a result of
such taking, is insufficient to pay all costs of such restoration work, Landlord
shall pay such "shortfall."

     SECTION 12.4 BASE RENT REDUCTION. In the event of a partial taking of the
Demised Premises under Section 12.2 hereof, followed by Tenant's election not to
terminate this Lease, the fixed Base Rent payable hereunder during the period
from and after the date of vesting of title pursuant to such Proceedings to the
earlier of the termination of this Lease or until the next date upon which Rent
is determined under Section 3.1 hereof, shall be determined by multiplying the
applicable Base Rent then being paid by Tenant, by a fraction, the numerator of
which is the square footage of Landlord's Improvements after such taking and
after the same has been restored to a complete architectural unit, and the
denominator of which is the square footage of Landlord's Improvements
immediately prior to such taking.

                                  ARTICLE 13
                         ASSIGNMENT, SUBLETTING, ETC.

     SECTION 13.1 PERMITTED TRANSFEREE OF TENANT. Tenant shall not sublet the
Demised Premises, or any portion thereof, nor assign, mortgage, pledge, transfer
or otherwise encumber or dispose of this Lease, or any interest herein, or in
any manner assign, mortgage, pledge, transfer or otherwise encumber or dispose
of its interest or estate in the Demised Premises, or any portion

                                       48
<PAGE>
 
thereof, without obtaining Landlord's prior written consent, which consent shall
not be unreasonably withheld provided, however, that such consent shall not be
required if (i) such assignment results from the merger of Tenant into another
entity (provided that the majority of the assets of Tenant are owned by the
entity resulting from such merger) or an assignment to an entity which purchases
all or substantially all of the assets of the Tenant, or (ii) Tenant shall
remain principally liable thereafter, and shall not thereby be relieved of
principal liability, for the due and faithful performance of all of terms of
this Lease. Tenant shall pay, on behalf of Landlord, any and all costs of
Landlord, including, without limitation, reasonable attorneys' fees, occasioned
in connection with any proposed sublease, assignment, mortgage, pledge, transfer
or other encumbrance or disposal of this Lease, or any interest herein, by
Tenant.

     SECTION 13.2 SUBSEQUENT ASSIGNMENTS. Anything in this Lease to the contrary
notwithstanding, and notwithstanding any consent by Landlord to any sublease of
the Demised Premises, or any portion thereof, or to any assignment of this Lease
or of Tenant's interest or estate in the Demised Premises, or any other
permitted sublease or assignment hereunder, no sublessee shall assign its
sublease nor further sublease the Demised Premises, or any portion thereof, and
no assignee shall further assign its interest in this Lease or its interest or
estate in the Demised Premises, or any portion thereof, nor sublease the Demised
Premises, or any portion thereof, without Landlord's prior written consent in
each and every instance, which consent may be given or withheld in Landlord's
sole discretion. No such subsequent assignment or subleasing shall relieve
Tenant from any of Tenant's obligations in this Lease.

     SECTION 13.3 PROFIT. If Landlord consents to an assignment or subletting as
provided above, or if the consent of Landlord to the assignment is not required,
or if Tenant remains principally liable on the Lease and Landlord's consent is
therefore not required, and if the sums of money or compensation paid by a
sublessee or assignee exceed the sums required to be paid by Tenant hereunder,
all of such excess shall be retained by Tenant.

     SECTION 13.4 INEFFECTIVE ASSIGNMENT. Tenant's failure to comply with all of
the foregoing provisions and conditions of this Article 13 shall (regardless of
whether Landlord's consent is required under this Article 13), at Landlord's
sole option, render any purported assignment or subletting null and void and of
no force and effect.

     SECTION 13.5 LANDLORD'S CONVEYANCE OR OTHER DISPOSITION. The Landlord shall
not convey or otherwise dispose of its interest in the Demised Premises (other
than assignments or mortgages in connection with the financing of the Demised
Premises), until the Initial Term Commencement Date has passed. If there is a
dispute between Landlord and Tenant in respect to whether all of the Punchlist
Items have been completed substantially in accordance with the Final Plans, the
Architect's determination of such completion shall be binding on Landlord and
Tenant.

      SUBORDINATION, NON-DISTURBANCE, NOTICE TO MORTGAGEE AND ATTORNMENT

     SECTION 14.1 SUBORDINATION. This Lease and all rights of Tenant herein, and
any and all

                                       49
<PAGE>
 
interest or estate of Tenant in the Demised Premises, or any portion thereof,
shall be subject and subordinate to the lien of any and all mortgages, deeds of
trust, security instruments, ground or underlying leases or other documents of
like nature, which at any time may be placed upon the Demised Premises, or any
portion thereof, by Landlord, and to any replacements, renewals, amendments,
modifications, extensions or refinancing thereof (herein individually referred
to as a "Mortgage," and collectively herein referred to as "Mortgages"), and to
each and every advance made under any and all Mortgages. Tenant agrees at any
time hereafter, and from time to time on demand of Landlord, to promptly execute
and deliver to Landlord any and all reasonable instruments, releases or other
documents which may reasonably be required for the purpose of subjecting and
subordinating this Lease to the lien of any and all such Mortgages, and which do
not alter the terms, provisions or conditions of this Lease (hereinafter
individually referred to as a "Subordination Agreement," and hereinafter
collectively referred to as "Subordination Agreements"). So long as there exists
no Default, no such Subordination Agreement shall interfere with, hinder or
reduce Tenant's right to quiet enjoyment under this Lease, nor the right of
Tenant to continue to occupy the Demised Premises, and all portions thereof, and
to conduct its business thereon, all in accordance with the covenants,
conditions, provisions, terms and agreements of this Lease. Each such
Subordination Agreement shall provide for the non-disturbance of Tenant's rights
hereunder, provided that Tenant attorns to the holder of the Mortgage which is
the subject thereof.

     SECTION 14.2 MORTGAGEE PROTECTION CLAUSE. Tenant shall deliver to each and
every holder of a Mortgage ("Mortgagee"), whose identify and address have been
provided to Tenant, a copy of any notice from Tenant to Landlord in which Tenant
advises Landlord of any act or omission on the part of Landlord which, after the
expiration of the applicable cure period, would constitute a default by Landlord
of its obligations under this Lease. After the expiration of all applicable cure
periods afforded Landlord in respect to such act or omission, Tenant shall
advise the Mortgagee, in writing, of the same as a condition precedent to Tenant
initiating any action under this Lease against Landlord, and Tenant, for an
additional thirty (30) days after the date of Mortgagee's receipt of such
notice, shall allow Mortgagee the option to remedy such act of omission of the
Landlord.

     SECTION 14.3 ATTORNMENT. If any Mortgagee shall succeed to the rights of
Landlord under this Lease or to ownership of the Demised Premises, whether
through possession or foreclosure or the delivery of a deed to the Demised
Premises in lieu of foreclosure, then, upon the written request of such
Mortgagee so succeeding to Landlord's rights hereunder, and provided that such
Mortgagee assumes, in writing, the obligations of Landlord hereunder accruing on
and after the date such Mortgagee acquires title to the Demised Premises, Tenant
shall attorn to and recognize such Mortgagee as Tenant's landlord under this
Lease, and shall promptly execute and deliver any and all reasonable instruments
which such Mortgagee may reasonably request to evidence such attornment. In the
event of any other transfer of Landlord's interest hereunder, upon the written
request of the transferee and Landlord, and provided that such transferee
assumes, in writing, the obligations of Landlord hereunder accruing on and after
the date of such transfer, Tenant shall attorn to and recognize such transferee
as Tenant's landlord under this Lease, and shall promptly execute and deliver
any and reasonable instruments which such transferee and Landlord may reasonably
request to evidence such attornment.

     SECTION 14.4 COSTS. Landlord agrees to reimburse Tenant for its reasonable
fees of outside counsel incurred in connection with the review of any
Subordination Agreements or Estoppel Letter, which Landlord may request Tenant
to execute.

     SECTION 15.1   SIGNS.  During the first one hundred eighty (180) days of
the Term, without Landlord's prior written consent, Tenant may erect signs
depicting the name and/or corporate logo of Tenant on the exterior or interior
of the Improvements or on the landscaped area adjacent thereto ("Original
Signage"); provided, however, that the Original Signage (a) does not cause any
structural damage or other damage to any of the Improvements or landscaping; (b)
does not violate applicable governmental laws, ordinances, rules or regulations;
and (c) does not violate any existing restrictions affecting the Demised
Premises, including, without limitation, Park covenants.  Any changes to the
Original Signage that Tenant wishes to make shall require Landlord's prior
written consent, which consent shall not be unreasonably withheld, conditioned
or delayed; provided, however, Landlord's consent to a change in the Original
Signage shall not be required, if such change complies with the foregoing
Original Signage requirements and is consistent changes to the Tenant's name
and/or corporate logo.

     SECTION 16.1   TRADE FIXTURES.  It is the intent of the parties that Trade
Fixtures shall include only those items of Tenant's furniture, equipment,
machinery, partitions and other personal property (including any items which are
affixed to the Demised Premises in a manner that can be readily detached without
significant damage to the Demised Premises) which are specifically used by
Tenant in the conduct of its business. Regardless of the foregoing, the Landlord
acknowledges that the items of property set forth on Exhibit 16.1 attached
hereto and made a part hereof, are Trade Fixtures and can be replaced and
disposed of by the Tenant, in Tenant's sole discretion.


                                  ARTICLE 17
                            CHANGES AND ALTERATIONS

     SECTION 17.1   CHANGES AND ALTERATIONS.  Tenant shall have the right, at
any time and from time to time during the Term, to make such changes and
alterations, structural or otherwise, to the Initial Interior Build-Out (or the
interior build-out hereunder for the Expansion Improvements, if applicable), as
Tenant shall reasonably deem necessary in connection with the requirements of
its business; provided, however, that any and all such changes, other than
changes or alterations of Tenant's Trade Fixtures ("New Work"), shall be made,
in all cases, subject to the following conditions, which Tenant covenants to
observe and perform:

     (a)  No New Work shall be undertaken until Tenant shall have
          first procured and paid for, so far as the same may be
          required from time to time, all municipal, state and federal
          permits and authorizations of the various governmental
          bodies and departments having jurisdiction of the Demised
          Premises or the proposed changes or alterations. Landlord
          shall join in the application for

                                       51
<PAGE>
 
          such permits or authorizations whenever such action is
          necessary, all at Tenant's sole cost and expense; provided,
          however, that (i) no such applications shall cause Landlord
          to become liable for any cost, fees or expenses, and (ii) at
          Landlord's direction, and in Landlord's sole discretion, any
          and all such permits or authorizations shall be terminated
          at the expiration of the Term.

     (b)  In any undertaking of Tenant pursuant to this Article 17,
          except in the instance of either (i) interior decorating,
          painting, carpentry or similar interior work, or (ii) New
          Work which (A) will not, in Landlord's reasonable judgment,
          impact the structure, or the mechanical, heating,
          ventilating, air conditioning, plumbing, electrical, or fire
          or health safety systems, of any of the Improvements or any
          other portion of the Demised Premises, and (B) in the
          aggregate will not cost in excess of One Hundred Thousand
          and 00/100ths Dollars ($100,000.00), no New Work shall be
          undertaken until detailed plans and specifications therefor
          have been first submitted to and approved in writing by
          Landlord, which approval shall not unreasonably be withheld;
          provided, however, that if, in Landlord's reasonable
          judgment, any such New Work would tend to impair the value
          or usefulness to Landlord of the Demised Premises, or any
          substantial portion thereof, or would tend to alter
          unreasonably the aesthetics of the Demised Premises, then
          Landlord shall not, under any circumstances, be obligated to
          approve such plans and specifications. Among other things,
          Landlord may condition its approval of any such New Work on
          Tenant's agreement to restore or remove all or any portion
          thereof at the expiration of the Term. Further, before the
          commencement of any New Work (including, without limitation,
          New Work falling within the exception set forth in the first
          paragraph of this Section 17.1(b)), Tenant shall (i)
          guarantee to Landlord (and demonstrate to Landlord's
          reasonable satisfaction, Tenant's financial status and
          creditworthiness sufficient to secure such guarantee) the
          completion thereof within a reasonable time thereafter, (A)
          free and clear of all mechanic's liens or other liens,
          encumbrances, security interests and charges, and (B) in
          accordance with the plans and specifications approved by
          Landlord; and (ii) Tenant shall promptly upon the completion
          of the New Work deliver to Landlord two (2) complete sets of
          "as built" drawings for the New Work.

     (c)  Any change or alteration shall not, when completed, reduce
          the area or cubic content of the Improvements, nor change
          the character of the Demised Premises as to use, without
          Landlord's express written consent (which may be withheld,
          as aforesaid).
 
     (d)  All New Work shall be done promptly and in a good and workmanlike
          manner and in Compliance with Laws and in accordance with the orders,
          rules and regulations of the Board of Fire Underwriters where the
          Demised Premises are located, or any other body exercising similar
          functions.  The cost of any and all such changes or alterations shall
          be paid by Tenant, so that the Demised Premises and all portions
          thereof shall at all times be free of liens for labor and materials
          supplied to the 

                                       52
<PAGE>
 
          Demised Premises, or any portion thereof. The New Work shall be
          prosecuted with reasonable dispatch, delays due to strikes, lockouts,
          acts of God, inability to obtain labor or materials, governmental
          restrictions or similar causes beyond the reasonable control of Tenant
          excepted. Tenant shall obtain and maintain, and shall cause its
          contractors, subcontractors and sub-subcontractors to obtain and
          maintain, at Tenant's or their sole cost and expense, during the
          performance of the New Work, workers' compensation insurance covering
          all persons employed in connection with the New Work and with respect
          to which death or injury claims could be asserted against Landlord or
          Tenant or against the Demised Premised, or any interest therein,
          together with comprehensive general liability insurance for the mutual
          benefit of Landlord, Landlord's Mortgagees and Tenant, with limits of
          not less than Two Million and 00/100ths Dollars ($2,000,000.00) in the
          event of injury to one person, Two Million and 00/100ths Dollars
          ($2,000,000.00) in respect to any one accident or occurrence, and Two
          Million and 00/100ths Dollars ($2,000,000.00) for property damage. The
          fire insurance with "extended coverage" endorsement required by
          Section 5.1 hereof shall be supplemented with "builder's risk"
          insurance on a completed value form or other comparable coverage on
          the New Work. All such insurance shall be in a company or companies
          which are authorized to do business in the Commonwealth of
          Pennsylvania and which are reasonably satisfactory to Landlord. All
          such policies of insurance or certificates of insurance shall be
          delivered to Landlord endorsed "Premium Paid" by the company or agency
          issuing the same, or with other evidence of payment of the premium
          satisfactory to Landlord, prior to the commencement of any New Work.
          From time to time from and after the date of this Lease, and within
          ten (10) days after Landlord's reasonable request therefor, Tenant
          shall provide Landlord with reasonable written evidence of the
          insurance required hereunder being in full force and effect.
          
     (e)  All improvements and alterations (other than Tenant's Trade Fixtures)
          made or installed by Tenant shall immediately, upon completion or
          installation thereof, become the property of Landlord, without payment
          therefor by Landlord, and shall be surrendered to Landlord on the
          expiration of the Term (unless the parties agree in writing to the
          contrary).
 
     (f)  No New Work shall be in, or connect the Demised Premises with, any
          other space, property, building or improvement, nor shall the same
          obstruct or interfere with any then existing easement.
 
     (g)  If Landlord requires Tenant, in Landlord's reasonable discretion, to
          restore or remove any New Work, Landlord shall so notify Tenant by
          written notice, given at the time of Landlord's approval of such
          requested change or alteration.  If Landlord so notifies Tenant, then
          at the expiration of the Term, Tenant shall remove any such New Work
          and, at Tenant's sole cost and expense, restore any damage caused to
          the Demised Premises as a result of such removal.

                             SURRENDER OF PREMISES

     SECTION 18.1   SURRENDER OF POSSESSION.  Tenant shall, upon termination of
this Lease for any reason whatsoever, surrender to Landlord the Demised
Premises, together with any and all buildings, structures, fixtures and building
equipment or real estate fixtures upon the Demised Premises and any and all
additions, alterations and replacements thereof (except Tenant's personalty and
Trade Fixtures), in good order, condition and repair, with all electrical
systems, plumbing systems, heating, ventilating and air conditioning systems,
fire protection systems, and other mechanical systems in good working order and
repair, reasonable wear and tear excepted (provided that such exception shall in
no way be deemed to relieve Tenant from its obligations to make all necessary
Tenant Repairs and Maintenance as and when required hereunder).

     SECTION 18.2   NO SURRENDER WITHOUT ACCEPTANCE.  No surrender to Landlord
of this Lease or of the Demised Premises, or any portion thereof, or any
interest therein, prior to the expiration of the Term, shall be valid or
effective unless agreed to and accepted in writing by Landlord (which agreement
Landlord may give or withhold in its sole discretion), and consented to in
writing by all Mortgagees and contract purchasers, if any (which consent may be
given or withheld in their respective sole discretion).  Further, no act or
omission by Landlord, or any representative or agent of Landlord, other than
such a written acceptance by Landlord, which is consented to by all Mortgagees
and contract purchasers, if any, shall constitute an acceptance of any such
surrender.

     SECTION 18.3   REMOVAL OF TENANT'S PROPERTY; HOLDOVER RENT.  Except as
otherwise provided herein, at the expiration of the Term, Tenant shall surrender
the Demised Premises, and shall surrender all keys to the Demised Premises, to
Landlord at the place then fixed for the payment of Rent, and shall inform
Landlord of all combinations on locks, safes and vaults within the Demised
Premises, if any.  Except as otherwise provided herein, Tenant shall, at such
time, also remove all of its property (including, without limitation, its
personalty and all Trade Fixtures) therefrom and all New Work placed thereon by
Tenant, if so requested by Landlord pursuant to Section 17.1 hereof.  Tenant
shall repair any damage to the Demised Premises caused by such removal, and any
and all such property not so removed when required shall, at Landlord's option,
become the exclusive property of Landlord, or be disposed of by Landlord, at
Tenant's cost and expense, without further notice to or demand upon Tenant.

     If Tenant fails to surrender possession as required under this Section
18.3, then, for each month, or portion thereof, after the termination of the
Term or of Tenant's rights of possession hereunder, whether by lapse of time or
otherwise, during which Tenant remains in possession of the Demised Premises, or
any portion thereof, after such termination, Tenant shall pay to Landlord, in
addition to Additional Rent, a sum equal to one hundred fifty percent (150%) of
the Base Rent herein provided for the month immediately prior to such
termination.  The provisions of this Section 18.3 shall not be deemed to limit
or constitute a waiver of any other rights or remedies of Landlord provided
herein at law or at equity, and Landlord's acceptance of the additional rent in
the event of a holdover by Tenant shall not act as a waiver or limitation on any
such other rights or remedies 

                                       54
<PAGE>
 
(including, without limitation, any direct, indirect or consequential damages).

     All property of Tenant not removed on or before the last day of the Term
shall be deemed abandoned.  Tenant hereby appoints Landlord as its agent to
remove all property of Tenant from the Demised Premises upon the termination of
this Lease, and to cause the transportation and storage thereof for Tenant's
benefit, all at the sole cost and risk of Tenant.  Landlord shall not be liable
for damage, theft, misappropriation or loss thereof, and Landlord shall not be
liable in any manner in respect thereto.  Tenant shall pay all costs and
expenses of such removal, transportation and storage.  Tenant shall reimburse
Landlord, immediately upon demand, for any expenses incurred by Landlord with
respect to any removal or storage of abandoned property and with respect to
restoring the Demised Premises to good order, condition and repair.

                           MISCELLANEOUS PROVISIONS

     SECTION 19.1   RIGHT OF INSPECTION.  Upon reasonable advance notice to
Tenant (except for emergency situations), Tenant agrees to permit Landlord and
its authorized representatives to enter upon the Demised Premises at all
reasonable times during ordinary business hours for the purpose of inspecting
the same and, pursuant to the terms of this Lease, making any necessary repairs
to comply with any laws, ordinances, rules, regulations or requirements of any
public body, or the Board of Fire Underwriters, or any similar body.  Except as
otherwise provided herein, nothing shall imply any duty upon the part of
Landlord to do any such work which, under any provision of this Lease, Tenant
may be required to perform, and the performance thereof by Landlord shall not
constitute a waiver of Default in failing to perform the same.  Landlord shall
not unreasonably interfere with the use and occupancy of the Demised Premises
pursuant to the provisions of this Section 19.1.

     SECTION 19.2   DISPLAY OF DEMISED PREMISES.  Upon reasonable advance notice
to Tenant, Landlord may, at any time during normal business hours during the
Term, enter upon the Demised Premises and exhibit the same for the purpose of
mortgaging or selling the same; provided, however, that during the final twelve
(12) months of the then-current Term, Landlord shall be entitled to display the
Demised Premises for sale or lease upon twenty-four (24) hours prior notice, and
shall be allowed to post appropriate signage in or about the Demised Premises,
so long as the same does not unreasonably interfere with Tenant's business.

     SECTION 19.3   INDEMNITIES.

     (a)  Tenant.  To the fullest extent allowed by law, except to the extent
          ------                                                             
the same is otherwise expressly waived by Landlord under this Lease (including,
without limitation, in Section 5.4 hereof), Tenant shall, at all times,
indemnify and save Landlord, and its partners, directors, officers,
shareholders, contractors, subcontractors, sub-subcontractors, Mortgagees,
agents and employees, harmless from and against any and all loss, cost or
damage, including, without limitation, reasonable attorneys' fees, incurred or
sustained by any of them in connection with the conduct or management, or from
any work or things whatsoever done in or about the Demised Premises during the
Term, and will further indemnify and save them harmless from and against any and
all loss, cost or damage, including, without limitation, reasonable attorneys'
fees, arising during 

                                       55

the Term, from any condition of the Demised Premises, or arising from any breach
or default on the part of Tenant in the performance of any covenant or agreement
on the part of Tenant to be performed, pursuant to the terms of this Lease, or
arising from any negligence of Tenant, its partners, directors, officers,
shareholders, contractors, subcontractors, sub-subcontractors (other than
Landlord, Contractor or their respective subcontractors or sub-subcontractors),
agents, employees or invitees, or arising from any accident, injury or damage
whatsoever caused to any person or entity during the Term, in or about the
Demised Premises. The indemnity obligations of Tenant under this Section 19.3
which relate directly or indirectly to death, bodily or personal injury or
property damage, shall be insured by contractual liability endorsement on
Tenant's policies of insurance required under the provisions of Article 5
hereof. Anything in this Section 19.3(a) to the contrary notwithstanding,
Tenant's indemnification obligations as aforesaid shall not apply to any claims,
costs, liabilities, actions and damages which arise as a result of (i) the
negligence or wrongful acts or omissions of Landlord or Contractor (or their
respective partners, directors, officers, shareholders, contractors,
subcontractors, sub-subcontractors, agents or employees); or (ii) the failure of
either Landlord or Contractor to comply with a provision of this Lease.

     (b)  Landlord.  To the fullest extent allowed by law, except to the extent
          --------                                                             
the same is otherwise expressly waived by Tenant under this Lease (including,
without limitation, in Section 5.4 hereof), Landlord shall at all times shall
indemnify and save Tenant, and its partners, directors, officers, shareholders,
contractors, subcontractors, sub-subcontractors, agents and employees, harmless
from and against any and all loss, cost or damage, including, without
limitation, reasonable attorneys' fees, incurred or sustained by any of them in
connection with the conduct of or the failure to conduct any of Landlord's
obligations hereunder, or any negligence in the performance thereof.  Anything
in this Section 19.3(b) to the contrary notwithstanding, Landlord's
indemnification obligations as aforesaid shall not apply to any claims, costs,
liabilities,  actions and damages which arise as a result of (i) the negligence
or wrongful acts or omissions of Tenant (or its partners, directors, officers,
shareholders, contractors, subcontractors, sub-subcontractors (other than
Landlord, Contractor or their respective contractors, subcontractors or sub-
subcontractors), agents, employees or invitees); or (ii) the failure of Tenant
to comply with a provision of this Lease.

be in writing.  All transmittals by Landlord or Contractor to Tenant shall be

                      Robert D. McCormick

     For Tenant:      Mr. Frank Timchak (limited to any changes and approved

     SECTION 19.6   QUIET ENJOYMENT.  Landlord covenants and agrees that Tenant,
upon paying the Rent, and upon observing and keeping the covenants, agreements
and conditions of this Lease on its part to be kept, observed and performed,
shall lawfully and quietly hold, occupy and enjoy the Demised Premises during
the Term without hindrance or molestation.

     SECTION 19.7   LANDLORD AND SUCCESSORS.  The term "Landlord," as used in
this Lease, so far as covenants or obligations on the part of Landlord are
concerned, shall be limited to mean and include only the owner or owners at the
time in question of the fee of the Demised Premises, and in the event of any
transfer or transfers or conveyance (provided that such grantee assumes in
writing the obligations of Landlord hereunder on and after the date of such
conveyance), the then grantor shall be automatically freed and relieved, from
and after the date of such transfer or conveyance, of all liability with respect
to any covenants or obligations on the part of Landlord contained in this Lease,
the performance of which first accrues on or after the date of such transfer;
provided, however, that any funds in the hands of such landlord or the then
grantor at the time of such transfer, in which Tenant has an interest, shall be
turned over to the grantee, and any amount then due and payable to Tenant by
Landlord or the then grantor under any provision of this Lease shall be paid to
Tenant.  It is intended that the covenants and obligations contained in this
Lease on the part of Landlord shall, subject to the aforesaid, be binding on
Landlord, its successors and assigns, only during and in respect of their
respective successive periods of ownership.

     SECTION 19.8   LIMITATION ON LANDLORD'S LIABILITY.  Tenant acknowledges and

(and if Landlord is a partnership, its partners, whether general or limited, and
if Landlord is a corporation, its directors, officers or shareholders) shall
never be personally liable for any personal judgment or deficiency decree or
judgment against it.

Landlord, certify by written instrument in substantially the form set forth as

     THIS  AMENDMENT NO. 2 TO BUILD-TO-SUIT LEASE AGREEMENT (the "Second
Amendment") is made this 18th day of January, 1999, by and among WALSH HIGGINS
NO. 33, L.P., a Pennsylvania limited partnership (hereinafter referred to as
"Landlord"), PENNSYLVANIA CELLULAR TELEPHONE CORP., a North Carolina corporation
(hereinafter referred to as "Tenant"), and WALSH, HIGGINS & COMPANY, an Illinois
corporation (hereinafter referred to as "Contractor").

                              W I T N E S S E T H

     WHEREAS, Landlord, Tenant and Contractor entered into that certain Build-
to-Suit Office Lease Agreement dated as of September 26, 1997, as amended by
Amendment No. 1 to Build-to-Suit Lease Agreement dated September 15, 1998
(collectively, the "Lease"), relating to certain premises located in Susquehanna
Township, Dauphin County, Pennsylvania more particularly described in the Lease;
and

     WHEREAS, Landlord, Tenant and Contractor desire to modify and amend the
Lease in certain respects as hereinafter provided.

     NOW, THEREFORE, for and in consideration of the premises, the sum of Ten
Dollars ($10.00) in hand paid by each of the parties hereto to the others, and
other good and valuable consideration, the receipt and sufficiency of which are
hereby acknowledged, Landlord, Tenant and Contractor do hereby covenant and
agree as follows.

     1.  Defined Terms.   The terms and words of art used herein, as indicated
         -------------                                                        
by the initial capitalization thereof, shall have the same respective meanings
given to such terms and words of art in the Lease.

     2.  Nonexclusive Assignment of Warranties.   Landlord, Tenant and
         -------------------------------------                        
Contractor acknowledge and agree that the assignment and transfer to Tenant of
assignable warranties required pursuant to the second sentence of Section 2.7 of
the Lease shall be a nonexclusive assignment so that such warranties shall be
owned and enforceable by each of Tenant and Landlord.

     3.  Limits of Liability Insurance.   In the event Tenant shall exercise an
         -----------------------------                                         
option to extend the Term of the Lease for any Renewal Term, Landlord may
require that the minimum limits of liability under the commercial general
liability insurance policy to be maintained by Tenant under Section 5.2(b) of
the Lease be increased during the applicable Renewal Term to the amount of
coverage then customarily required of new tenants of office space comparable to
the Demised Premises in the metropolitan Harrisburg, Pennsylvania area, and if
Landlord shall elect to require an increase in the minimum limits of such
liability insurance (which election shall be made by written notice to Tenant
given at any time during the applicable Renewal Term, but only once during such
Renewal Term), the minimum limits of liability under the commercial general
liability
<PAGE>
 
insurance required to be maintained by Landlord under Section 5.1(b) of the
Lease shall likewise be increased to an equivalent amount.

     4.  Change of Control.   Supplementing the terms and provisions of Article
         -----------------                                                     
13 of the Lease, Landlord and Tenant agree that if Tenant is a corporation, any
transfer of any of Tenant's issued and outstanding capital stock or any issuance
of additional capital stock, as a result of which the majority of the issued and
outstanding capital stock of Tenant is held by a person or persons who do not
hold a majority of the issued and outstanding capital stock of Tenant on the
date on which Tenant acquires its interest in this Lease, shall be deemed a
voluntary assignment of this Lease and subject to the provisions of this Article
13; provided, however, that this sentence shall not apply to the Tenant if (i)
at least fifty percent (50%) of the outstanding voting stock of the Tenant is
transferred to an entity that, prior to such transfer, controls, is controlled
by or is under common control with the Tenant, or (ii) all of the outstanding
voting stock of such corporation is registered under Section 12(b) or 12(g) of
the Securities and Exchange Act of 1934, as amended, after the transfer of such
stock.  If Tenant is a partnership or limited liability company, any transfer of
any interest in the partnership or limited liability company, directly or
indirectly, or any other change in the composition of the partnership or limited
liability company, directly or indirectly, which results in a change in the
control of Tenant shall be deemed a voluntary assignment of this Lease and
subject to the provisions of this Article 13.  Notwithstanding that a transfer
of Tenant's issued and outstanding capital stock or the issuance of additional
capital stock of Tenant or, if Tenant is a partnership or limited liability
company, any change in the control of Tenant shall be deemed a voluntary
assignment of this Lease subject to the provisions of this Article 13, such
assignment of this Lease is and shall be expressly permitted, provided that
Tenant shall have a net worth, determined after such transfer of stock, issuance
of capital stock or change in the control of Tenant, and determined in
accordance with generally accepted accounting principles, equal to or greater
than the net worth of Tenant prior to such transaction, and further provided
that any such transaction is not entered into as a subterfuge to avoid the
restrictions relating to assignments set forth in this Lease.

     5.  Amendments to Lease.   Landlord, Tenant and Contractor hereby agree
         -------------------                                                
that, notwithstanding anything contained in the second sentence of Section 19.14
of the Lease to the contrary, from and after the date hereof, Contractor shall
not be required to join in or be a party to any modification or amendment to the
Lease unless such modification or amendment affects the obligations and
liabilities of Contractor under the Lease.  No modification or amendment to the
Lease entered into solely by Landlord and Tenant which does not affect the
obligations and liabilities of Contractor under the Lease will modify or release
the obligations and liabilities of Contractor under the Lease.

     6.  Third Party Claims.  Landlord and Tenant hereby agree that the waiver
         ------------------                                                   
of claims by Landlord set forth in Section 19.17 of the Lease shall be
inapplicable to any crossclaims asserted by Landlord against Tenant resulting
from claims asserted against Landlord by any party unrelated to Landlord.
Likewise, Landlord and Tenant hereby agree that the waiver of claims by Tenant
set forth in Section 19.17 of the Lease shall be inapplicable to any crossclaims
asserted by Tenant against Landlord resulting from claims asserted against
Tenant by any party unrelated to Tenant.

     7.  Brokerage Fees Upon Expansion.   Landlord and Tenant acknowledge that

                            PAYMENT AND PERFORMANCE
                            -----------------------

     This Built-To-Suit Office Lease Agreement Guaranty ("Guaranty") is dated
this 26th day of September, 1997, and is made by VANGUARD CELLULAR FINANCIAL
CORP., a North Carolina corporation ("Guarantor")

                                   RECITALS
                                   ---------
                                        
     (A) Walsh, Higgins No. 33, L.P., a Pennsylvania limited partnership, as
landlord ("Landlord"), contemporaneously herewith entered into that certain
Build-To-Suit Lease Agreement ("Lease") with Pennsylvania Cellular Telephone
Corp., a North Carolina corporation, as tenant ("Tenant"), for the leasing of
that certain  property located on approximately 10.5 acres in Commerce Park in
Susquehanna Township, Dauphin County, Pennsylvania ("Premises").

     (B) Tenant is a wholly owned subsidiary of Guarantor's parent and Guarantor
will be benefited by Landlord entering into the Lease.

     NOW, THEREFORE, for and in consideration of the Lease, and other good and
valuable consideration the receipt and sufficiency are hereby acknowledged by
Guarantor, Guarantor agrees, for the benefit of Landlord and its successors and
assigns, as follows:

     1.   Recitals and Defined Terms.  The foregoing Recitals are deemed
          --------------------------                                         
remade and form a part of this Guaranty.  Unless otherwise defined herein, all
capitalized terms herein shall have the meanings ascribed to them in the Lease.

     2.   Guaranty.  Guarantor hereby unconditionally guarantees that
          --------                                                      
Tenant shall completely perform, within the time required under the terms of the
Lease, each and every Tenant's obligations under the Lease, and to the extent
that the Tenant fails to so do, shall pay all costs and expenses and shall pay,
perform and discharge all liabilities and obligations contained in the Lease.

     If Tenant does not do the matters above specified in this Paragraph 2 on or
before  the times such matters are to be done by Tenant in accordance with the
applicable provisions of the Lease after all notice and cure periods have
expired, Guarantor unconditionally and irrevocably covenants and agrees that it
shall, upon written notice from Landlord to Guarantor, at Guarantor's sole cost
and expense and within the time provided in Paragraph 5 hereof, undertake the
timely and complete discharge of each and every of Tenant's obligations, that
Tenant, under the terms of the Lease, failed to so discharge.

     3.   Direct Action Against Guarantor.  The Landlord shall have and may
          -------------------------------                                    
exercise, in addition to all other rights, privileges, or remedies available to
it hereunder, the specific right and
<PAGE>
 
remedy, exercisable by the Landlord, in its discretion, to sue for and obtain
specific performance by Guarantor of Guarantor's covenants set forth herein, all
at the cost of the Guarantor.

     4.   Indemnity.  In the event of any default by the Guarantor hereunder,
          ---------                                                            
the Guarantor shall indemnify and defend the Landlord against, and hold the
Landlord harmless from all liability, damage, cost and expense, including costs
of suit and reasonable attorneys' fees, other than to the extent caused by the
Landlord's negligent or willful misconduct, which the Landlord may incur by
reason of such default by Guarantor; provided, however, the damages for which
Guarantor shall indemnify Landlord hereunder shall not be any greater than the
damages which Landlord is permitted to recover from Tenant under the Lease,
without regard to any discharge, disaffirmation, rejection, stay or enforcement
restriction in bankruptcy, receivership or other proceeding of Tenant.

5.   Election of Enforcement.  Landlord shall deliver to Guarantor a copy of any
     -----------------------                                                    
notice from Landlord to Tenant in which Landlord advises Tenant of any act or
omission on the part of Tenant which, after the expiration of the applicable
cure period provided in the Lease, would constitute a default by Tenant of its
obligations under the Lease.  After the expiration of all applicable cure
periods afforded Tenant under the Lease in respect to such act or omission,
Landlord shall advise Guarantor, in writing, of the same as a condition
precedent to requiring any action of Guarantor hereunder, and Landlord, in the
instance of a monetary default by Tenant, shall afford Guarantor an additional
five (5) days in which to cure the monetary default of Tenant, and, in the
instance of a non-monetary default by Tenant, shall afford Guarantor an
additional thirty (30) days in which to cure the non-monetary default of Tenant.

     The Landlord may, at its option, after the expiration of the time periods
provided above in this Paragraph 5, proceed to enforce this Guaranty against the
Guarantor in the first instance without first proceeding against the Tenant or
any other person and without first resorting to any security that may be held by
the Landlord or to any other remedies, and the liability of Guarantor hereunder
shall be in no manner affected or impaired by any failure, delay, neglect,
omission or election by the Landlord not to realize upon or pursue any persons
or security liable for the obligations of the Tenant under the terms of the
Lease.

     6.   Modification of Obligations.  The Landlord, from time to time,
          ---------------------------                                     
without further notice to or assent from Guarantor and without in any manner
affecting the liability of Guarantor and upon such terms and conditions as it
may deem advisable, may: (a) extend in whole or in part, modify or release (or
consent to any of the foregoing) the obligations of the Tenant under the terms
of the Lease; and (b) settle, adjust or compromise any claim of the Landlord
against Tenant in respect to the obligations under the terms of the Lease. The
Guarantor hereby ratifies and confirms any such extension, renewal, change,
release, waiver, surrender, exchange, modification, impairment, substitution,
settlement, adjustment, compromise or consent and agree that the same shall be
binding upon the Guarantor, and the Guarantor hereby expressly waives any and
all defenses, counterclaims or offsets which the Guarantor might or could have
by reason thereof, it being understood that the Guarantor shall at all times be
bound by this Guaranty and remain liable to the Landlord, until each and every
of the obligations of Tenant under the terms of the Lease have been fully and
completely discharged, whereupon this Guaranty shall automatically terminate and
be of no further force and effect. The Guarantor
<PAGE>
 
agrees that its obligations hereunder shall not be discharged, limited or
otherwise affected by any circumstances which otherwise would constitute a legal
or equitable discharge of the Guarantor as surety or guarantor. Except as
hereafter provided, the Guarantor shall have any and all defenses available to
the Guarantor that are available to the Tenant under the Lease to any claim made
by Landlord under the terms of this Guaranty for the non-performance or payment
by the Tenant under the terms of the Lease; provided, however, Guarantor shall
not be discharged or released from or have a defense to any of its obligations
under this Guaranty by reason of (i) a discharge in bankruptcy, receivership or
other proceedings of Tenant, a disaffirmation or rejection of the Lease by a
trustee, custodian or other representative in bankruptcy, a stay or other
enforcement restriction, or any other reduction, modification, impairment or
limitation of the liability of Tenant under the Lease, or (ii) the provisions of
clause (b) of this paragraph 6 above provided. Nothing in this Guaranty shall be
construed as a waiver by the Guarantor of any rights or claims it may have
against the Landlord under this Guaranty or otherwise, but any recovery upon
such rights and claims shall be pursued against Landlord in a separate cause of
action and not as a claim of offset or counterclaim to any action brought
Landlord under this Guaranty.

     7.   Lease Modification.  Landlord may, without the consent of the
          ------------------                                             
Guarantor, at any time and from time to time: (a) amend any provisions of the
Lease, and (b) make any agreement with the Tenant for the extension, renewal,
modification, payment, compromise, discharge, exchange, settlement, waiver or
release of any provision of the Lease.

     8.   No Prior Action.  The Guarantor hereby waives all requirements that
          ---------------                                                      
the Landlord shall institute any action or proceedings at law or in equity
against the Tenant or anyone else as a condition precedent to bringing an action
against Guarantor under this Guaranty, and the Guarantor further agrees to make
and perform its obligations hereunder whether or not any one or more of the
following events have occurred: (a) Landlord has made any demand on Tenant; (b)
Landlord has taken any action of any nature against or has pursued any rights
which the Landlord has against any other person, partnership, corporation,
association, or entity who may be liable for performance of Tenant's obligations
under the terms of the Lease; or (c) Landlord has invoked any other remedies or
rights Landlord has available with respect to the obligations of the Tenant
under the terms of the Lease.  All remedies afforded to the Landlord by reason
of this Guaranty are separate and cumulative remedies and none of such remedies,
whether exercised by the Landlord or not, shall be deemed to be an exclusion of
any one of the other remedies available to the Landlord, and shall not in any
way limit or prejudice any other legal or equitable remedy available to the
Landlord.

     9.   No Release.  The Guarantor shall not be released by any act or
          ----------                                                        
thing which might, but for this provision of this Guaranty, be deemed a legal or
equitable discharge of a surety or guarantor, or by reason of any waiver,
extension, modification, forbearance or delay of the Landlord or its failure to
proceed promptly or otherwise in the enforcement of the Lease or this Guaranty,
and the Guarantor hereby expressly waives and surrenders any defense to its
liability under this Guaranty based upon any of the foregoing acts, things,
agreements or waivers.

     10.  Waiver of Demand.  Except as otherwise provided herein, the
          ----------------                                             
Guarantor hereby waives demand, protest, notice of protest and of dishonor,
notice of acceptance hereof, notices of
<PAGE>
 
default and all other notices now or hereafter provided by law.

     11.  Termination of Guaranty.  Except as hereafter provided, this
          -----------------------                                        
Guaranty shall terminate and be of no further force and effect, upon (i) the
expiration of the Term of the Lease, or (ii) the termination of the Lease by
Tenant in accordance with the provisions of the Lease, or (iii) Tenant's
assignment, in accordance with the terms of the Lease, of all of Tenant's right,
title and interest in and to the Lease to an assignee (x) whose (or its
guarantor's) net worth, determined in accordance with generally accepted
accounting principles, consistently applied, is be equal to or greater than the
net worth of Guarantor as of the date of this Guaranty, (y) against whom (or its
guarantor) there is no action or proceeding pending or threatened or against
whom (or its guarantor) there is no contingent liability that, if decided or
occurring against such assignee (or its guarantor), would have a material,
adverse affect on the then current net worth of such assignee (or its
guarantor), and (z) who executes an assumption agreement by and between Landlord
and such assignee (or whose guarantor executes a guaranty), on terms, provisions
and conditions reasonably acceptable to Landlord, pursuant to which such
assignee (or its guarantor) assumes each and every of the future obligations of
the Tenant under the terms of the Lease.  Notwithstanding the foregoing, in the
instance of clauses (i), (ii) and (iii) above, this Guaranty shall not terminate
in respect to any of those obligations of Tenant under the Lease that, at the
time of such expiration of the Term, termination of the Lease by Tenant or
assumption of Tenant's obligations under the Lease, had accrued, but were not
then fully discharged.  Except as provided in this Paragraph 11, the termination
of this Guaranty, upon the occurrence of any of the foregoing events, shall
occur simultaneously with the occurrence of any of the foregoing events, without
necessity of further notice.

     12.  Entire Agreement.  The Guarantor hereby agrees that this Guaranty
          ----------------                                                    
contains the entire agreement between the parties and there is and can be no
other oral or written agreement or understanding whereby the provisions of this
Guaranty have been or can be affected, varied, waived or modified in any manner
unless the same be set forth in writing and signed by the Landlord, and then
such waiver or consent shall be effective only in the specific instance and for
the specific purpose for which given.

     13.  Governing Law.  This Guaranty is and shall be deemed to be a
          -------------                                                 
contract entered into under and pursuant to the laws of the Commonwealth of
Pennsylvania and shall be binding upon the Guarantor and its successors and
assigns.

     14.  No Subrogation.  The Guarantor shall not, by reason of the
          --------------                                               
performance of the terms and provisions of this Guaranty, succeed to or be
subrogated to the rights and privileges of the Landlord against the Tenant or be
deemed to be the successor or assign of the Landlord.

     15.  Cost of Enforcement.  The Guarantor agrees to pay all costs and
          -------------------                                               
expenses which may be incurred by the Landlord, its successors and assigns, in
the enforcement of this Guaranty, including, but not limited to, reasonable
attorneys' fees through and including the costs of any appeals and any appellate
costs and regardless of whether any specific legal proceedings shall be
commenced in connection therewith.

legally described on Exhibit "A" to the Reconveyance Grant Deed) to Seller.  In
addition, if Buyer intends to encumber the Reconveyance Parcel with a deed of
trust or other lien (a "Buyer Lien") at the Closing or pending the reconveyance,
Buyer shall, at the time of such encumbrance, also deposit into Escrow an
irrevocable request for partial reconveyance ("Partial Reconveyance") from the
beneficiary of the Lien, in form sufficient for the Title Company to remove the
Lien from title to the Reconveyance Parcel.  The Reconveyance Grant Deed and
Partial Reconveyance will be held by Escrow Holder in a subescrow, which will
survive the Closing, and will be recorded by Escrow Holder, upon written request
of Seller, as soon as possible after the Lot-Line Adjustment has been approved
by the City and recorded in the Official Records of Orange County, California.
The only condition to Escrow Holder's use and recordation of the Grant Deed and
Partial Reconveyance shall be the City's approval to and recordation of the Lot-
Line Adjustment.  Buyer's commitment to reconvey the Reconveyance Parcel is a
material element of the consideration for the sale of the Property hereunder,
and Buyer hereby covenants that (i) Buyer will cooperate (without obligation to
incur any out-of-pocket expense other than with respect to any Partial
Reconveyance) with the processing of the necessary approvals and recordation of
the Lot-Line Adjustment, including promptly executing any necessary post-Closing
applications and documents as the owner of Lot 9; (ii) Buyer will not allow the
Reconveyance Parcel to be transferred, occupied or encumbered in any way between
the Closing and the date the Reconveyance Grant Deed is recorded (except for a
Buyer Lien, so long as Buyer escrows the Partial Reconveyance as provided
above); and (iii) any applications made by Buyer for permits, entitlements or
changes to entitlements for the Property shall presume and be consistent with
the configuration of the Property after the Lot-Line Adjustment and reconveyance
of the Reconveyance Parcel to Seller.  Buyer's covenants set forth in this
Section 1.4 shall survive the Closing.

shall prevail.

10.  DEFAULT AND INDEMNIFICATION
     ---------------------------

     10.1  Buyer's Default.
           --------------- 

           (a)  Default.  Buyer shall be deemed to be in default hereunder if
                -------                                                      
Buyer fails, for any reason other than Seller's default hereunder or the failure
of a condition precedent to Buyer's obligation to perform hereunder, to meet,
comply with or perform any covenant, agreement or obligation on its part
required within the time limits and in the manner required in this Agreement, or
there shall have occurred a material breach of any representation or warranty
made by Buyer; provided, however, no such default shall be deemed to have
occurred unless and until Seller has given Buyer written notice thereof,
describing the nature of the default, and Buyer has failed to cure such default
within five (5) Business Days of the receipt 

                                       17
<PAGE>
 
of such notice (but in any event before the Closing Date, unless such default
occurs after Closing).

           (b)  LIQUIDATED DAMAGES.  IF THE CLOSING FAILS TO OCCUR BY REASON OF
                ------------------                                             
DEFAULT OF BUYER UNDER THE TERMS OF THIS AGREEMENT, BUYER SHALL BE RESPONSIBLE
FOR ALL CANCELLATION CHARGES REQUIRED TO BE PAID TO ESCROW HOLDER AND ANY ESCROW
CHARGES.  IN ADDITION, THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF THE
PARTIES SHALL TERMINATE AND THE DEPOSIT AND ALL INTEREST ACCRUED THEREON SHALL
BE IMMEDIATELY DELIVERED BY ESCROW HOLDER TO SELLER ON SELLER'S REQUEST.  THE
DEPOSIT SHALL BE DEEMED LIQUIDATED DAMAGES FOR BUYER'S FAILURE TO ACQUIRE THE
PROPERTY AS SELLER'S SOLE AND EXCLUSIVE REMEDY AGAINST BUYER AT LAW OR IN EQUITY
(INCLUDING, WITHOUT LIMITATION, SELLER'S RIGHTS TO SEEK SPECIFIC PERFORMANCE OF
THIS AGREEMENT AND TO RECEIVE DAMAGES FOR FAILURE TO ACQUIRE THE PROPERTY) WHICH
SUM SHALL BE PRESUMED TO BE A REASONABLE ESTIMATE OF THE AMOUNT OF ACTUAL
DAMAGES SUSTAINED BY SELLER BY REASON OF BUYER'S BREACH OF ITS OBLIGATION TO
ACQUIRE THE PROPERTY.  FROM THE NATURE OF THIS TRANSACTION, IT IS IMPRACTICABLE
AND EXTREMELY DIFFICULT TO FIX THE ACTUAL DAMAGES THAT SELLER WOULD SUSTAIN,
SHOULD BUYER BREACH ANY OF ITS OBLIGATIONS.  THE IMPRACTICABILITY AND DIFFICULTY
OF FIXING ACTUAL DAMAGES IS CAUSED BY, WITHOUT LIMITATION, THE FACT THAT THE
PROPERTY IS UNIQUE.  GIVEN THE FOREGOING, AMONG OTHERS, BUYER AND SELLER AGREE
THAT LIQUIDATED DAMAGES ARE PARTICULARLY APPROPRIATE FOR THIS TRANSACTION AND
AGREE THAT SAID LIQUIDATED DAMAGES SHALL BE PAID IN THE EVENT OF BREACH BY
BUYER, NOTWITHSTANDING ANY WORDS OR CHARACTERIZATIONS PREVIOUSLY USED OR HEREIN
CONTAINED IMPLYING ANY CONTRARY INTENT, THE PAYMENT OF SUCH AMOUNT AS LIQUIDATED
DAMAGES IS NOT INTENDED AS A FORFEITURE OR PENALTY WITHIN THE MEANING OF
CALIFORNIA CIVIL CODE SECTION 3275 OR 3369, BUT IS INTENDED TO CONSTITUTE
LIQUIDATED DAMAGES TO SELLER PURSUANT TO CALIFORNIA CIVIL CODE SECTIONS
1671,1676 AND 1677.  NOTHING HEREIN SHALL, HOWEVER, BE DEEMED TO LIMIT BUYER'S
LIABILITY TO SELLER FOR DAMAGES OR INJUNCTIVE RELIEF FOR BREACH OF SECTIONS
                                                                   --------

     10.2  Seller's Default.
           ---------------- 

           (a)  Default.  Seller shall be deemed to be in default hereunder if
                -------                                                       
Seller fails, for any reason other than Buyer's default hereunder or the failure
of a condition precedent to Seller's obligation to perform hereunder, to meet,
comply with, or perform any covenant, agreement or obligation on its part
required within the time limits and in the manner required 

                                       18

in this Agreement, or there shall have occurred a material breach of any
representation or warranty (made by Seller); provided, however, no such default
shall be deemed to have occurred unless and until Buyer has given Seller written
notice thereof describing the nature of the default, and Seller has failed to
cure such default within five (5) Business Days of receipt of such notice (but
in any event before the Closing Date, unless such default occurs after Closing).

          (b)  Remedies.  If Seller shall be deemed to be in default under
               --------                                                   
Section 10.2(a) at or before Closing, and Buyer does not waive such default,
- ---------------                                                             
Buyer may pursue one of the following remedies, each of which shall be Buyer's
sole and exclusive remedy:

               (i)   Enforce specific performance of this Agreement against
Seller, in which case Buyer shall have no claim for damages or any other remedy
against Seller; or

               (ii)  Terminate this Agreement by written notice delivered to
Seller on or before the Closing Date and receive the Deposit and any other
monies deposited with Escrow Holder; or (ii) pursue such other remedies at law
or equity, as Buyer may determine in its sole discretion.

          (c)  Remedies After Closing.  Except to the extent loss, damage or
               ----------------------                                       
expense is caused by Seller's gross negligence or willful misconduct, if the
Closing has occurred, Buyer shall not be entitled to recovery from Seller for
breach of contract, for tort, or for any other reason unless Buyer establishes
that Seller shall have breached a representation or warranty contained in
Section 8.1 that has not terminated, or Seller has not performed a covenant to
- -----------                                                                   
eliminate or cure Title Objections pursuant to Section 4.1, in which case Buyer
                                               -----------                     
may seek actual and/or "out-of-pocket" damages by reason thereof, but shall not
be entitled to consequential or other damages or exemplary damages or any other
damages or remedy.

          (d)  Termination Procedure.  Upon termination of this Agreement in
               ---------------------                                        
accordance with this Section 10.2, the Deposits shall be promptly returned to
                     ------------                                            
Buyer by the Escrow Holder upon  receipt by Escrow Holder of written notice from
Buyer advising that Seller has defaulted under this Agreement and Buyer elects
to terminate this Agreement pursuant to this Section 10.2 and, in the event such
                                             ------------                       
written notice is given after the Contingency Date, Seller's failure to object
to such termination within three (3) Business Days of receipt of written notice
from Escrow Holder of such election by Buyer.  Seller shall be responsible for
all cancellation charges and escrow charges required to be paid to the Escrow
Holder.

11.  CONDEMNATION.
     ------------ 

     If before Closing any action or proceeding is commenced for the
condemnation or exercise of the rights of eminent domain of the Property or any
portion thereof, or if Seller is notified by the duly authorized officer of a
duly empowered condemning authority, then at Buyer's option either (i) at
Closing Seller shall assign and turn over, and Buyer shall be entitled to keep,
all awards for the taking by eminent domain which accrue to Seller and the
parties shall proceed with the Closing, without modifying the terms of this
Agreement and without reducing the Purchase Price, or (ii) Buyer may terminate
this Agreement in which case the Deposits shall 

                                       19

     Construction Agreement and the Lease. The Manager shall coordinate with the
     Architect and the Contractor an orderly and expeditious transition from the

                              ------------------

     5.1  Implementation of Development Budget.  The Owner hereby approves the
          ------------------------------------                                  
Development Budget and the Manager is hereby authorized and directed to
implement the Development Budget pursuant to this Agreement. The Manager may,
without the need for any further approval whatsoever by the Owner, make any
expenditures and incur any obligations provided for in the Development Budget,
as it may be revised from time to time as provided herein. The Manager shall use
prudence and diligence and shall employ its best efforts to ensure that the
actual costs incurred for each category or line item of expense as set forth in
the Development Budget shall not exceed such category or line item in the
Development Budget. The Manager shall advise the Owner promptly if it appears
that costs in any category or line item specified in the Development Budget will
exceed the amount budgeted therefor. All expenses shall be charged to the proper
category or line item in the Development Budget, and no expenses may be
classified or reclassified for the purpose of avoiding an excess in the budgeted
amount of a category or line item without the Owner's prior written approval.
The Manager shall secure the Owner's prior written approval before incurring and
paying any cost which will result in aggregate expenditures under any one
category or line item in the Development Budget exceeding the amount budgeted
therefor.

     5.2  Revision of Development Budget.  If the Manager at any time determines
          ------------------------------                               
that the Development Budget is not compatible with the then-prevailing status of
the Project and does not adequately provide for the completion of the Project,
the Manager shall promptly prepare and submit to the Owner an appropriate
revision of the Development Budget. Any such revision shall require the approval
of the Owner; provided, however, that any such revision shall be considered
approved on the fourteenth (14th) day following its delivery to the Owner,
unless the Owner shall, within such fourteen (14) day period, notify the Manager
in writing of its disapproval of the proposed revision and specify in such
notice the items to which it objects. In the event of any such objection, the
Manager and the Owner shall consult and endeavor to reconcile their differences.

     5.3  Emergencies.  Notwithstanding any limitations herein provided, the
          -----------                                                         
Manager may spend funds or incur expenses on behalf of the Owner in
circumstances which the Manager reasonably and in good faith believes constitute
an emergency requiring prompt action to avert, or reduce the risk of, damage to
persons or property. The Manager shall, in any case, notify the Owner as soon as
practicable of the existence of such emergency and of the action taken by the
Manager with respect thereto.

     5.4  Reduction in Fees.  In the event that the total of all costs and
          -----------------                                                 
expenses actually incurred by the Owner with respect to the acquisition of the
Land and the planning, design, development, construction and completion of the
Project and the Tenant Improvements for Tenant under the Lease (including costs
in all categories or line items specified in the Development Budget, but
expressly excluding costs for the specific line items marked with a double
asterisk in the Development Budget, and net of amounts reimbursed to the Owner
by Tenant with respect to Tenant Improvements for Tenant) shall exceed
$______________, the amount of the fees payable to the Manager under Section
11.2 hereof shall be reduced by the 

                                      -10-
<PAGE>
 
amount of such excess, with any reductions to be applied to such fees in the
following order of priority:

     (a) first, to unpaid portions of the Development Fee until the remaining
     Development Fee is reduced to zero;

     (b) then to any portion of the Development Fee which has theretofore been
     paid to the Manager until all such fees have been reduced to zero, and the
     Manager hereby agrees to reimburse to the Owner an amount of such fees
     theretofore paid to the Manager as shall equal the amount of such
     reduction.

The aforesaid reductions in the fees payable to the Manager under Section 11.2
hereof shall be effected regardless of whether or not appropriate revisions of
the Development Budget are approved by the Owner and regardless of whether or
not any increases in costs and expenses incurred by the Owner with respect to
the acquisition of the Land or the planning, design, development, construction
and completion of the Project and the Tenant Improvements for Tenant are
approved by the Owner; provided, however, in the event such costs and expenses
                       --------  -------                                      
shall increase as a result of a change by the Owner in the scope of the work
comprising the Project, the incremental costs due to the change in the scope of
the work shall not cause a reduction in the fees payable to the Manager under
Section 11.2 hereof.  The Owner shall not be obligated to accept or agree to
changes in the scope of the work comprising the Project in order to reduce the
costs and expenses with respect thereto.  The Owner and the Manager agree that
appropriate reductions in the fees payable to the Manager (and reimbursements
thereof to the Owner, if applicable) shall be effected as and when it is
reasonably determined by the Owner that the costs and expenses under any
category or line item in the Development Budget shall exceed the amount
originally budgeted therefor or that costs and expenses will be incurred that
are not originally budgeted under the Development Budget; provided, however, the
Owner and the Manager shall make reasonable allocations of the "contingency"
category or line item in the Development Budget to other categories or line
items prior to effecting a reduction in the fees payable to the Manager, so long
as a reasonable reserve is maintained in the "contingency" category or line item
to cover future contingencies.  Promptly following the Completion Date, the
Owner and the Manager shall make any final adjustments and payments between them
to give effect to the agreements set forth in this Section 5.4.

     8.1  Separate Accounts.  It is contemplated that the Owner will make
          -----------------                                                
disbursements with respect to the development and construction of the Project
directly to the Architect and the Contractor. Nevertheless, all disbursements
and other funds of the Owner which may be received by the Manager hereunder with
respect to the development or construction of the Project shall be deposited by
the Manager and held in such bank account or accounts maintained by the Manager
in such bank or banks with federal deposit insurance protection as may be
selected by the Manager and approved by the Owner. All such funds shall be and
shall remain the property of the Owner and shall be disbursed by the Manager in
payment of the obligations of the Owner incurred in connection with the
development and construction of the Project, or, subject to the provisions of
Section 8.2 below, shall be disbursed to the Owner at the Owner's request.
Except as hereinafter provided, the Manager shall not commingle the Owner's
funds with the funds of any other person.

     8.2  The Owner's Duty to Provide Funds.  The Owner agrees that the Owner
          ---------------------------------                                    
will pay all current obligations of the Owner in accordance with the Development
Budget, including all obligations of the Owner to the Manager hereunder.
Alternatively, at the Owner's option, the Owner may elect to provide funds to
the Manager so that the Manager can pay all such obligations of the Owner
(excluding obligations to the Manager, it being understood and agreed that such
obligations to the Manager shall be paid directly by the Owner to the Manager).
If the Owner elects to cause the Manager to make payment of such obligations,
the Owner hereby agrees that, by making deposits to (following notice as
provided below), or by refraining from withdrawing funds from, the bank account
or accounts maintained by the Manager pursuant to Section 8.1 above, the Owner
shall, during the term of this Agreement, maintain sufficient funds in such bank
account or accounts to enable the Manager to pay all current obligations of the
Owner in accordance with the Development Budget, excluding the obligations of
the Owner to the Manager hereunder. Accordingly, the Owner shall, within ten
(10) days of its receipt of any written request from the Manager for additional
funds (which request must specify the amount of such funds requested and the
purposes for which they are to be used), deposit in such bank account or
accounts such additional funds as the Owner shall consider appropriate with
respect to such request by the Manager.

     8.3  Investment of Owner's Funds.  If at any time there are in the bank
          ---------------------------                                         
account or accounts established pursuant to Section 8.1 above, funds of the
Owner, from whatever sources,

temporarily exceeding the immediate cash needs of the Project, the Manager may
(and at the discretion of the Owner shall) invest such excess funds in such
savings accounts, certificates of deposit, United States Treasury obligations,
commercial paper, and the like, as the Manager shall deem appropriate or as the
Owner shall direct, provided that the form of any such investment shall be
consistent with the Manager's need to be able to liquidate any such investment
to meet the cash needs of the Project from time to time.

liability to the Owner for any errors of judgment, or any mistakes of fact or of

responsibilities under this Agreement, unless the Manager has failed to exercise
that degree of care and skill which a reasonable and diligent businessman in the
Manager's profession would exercise in transactions of a similar nature for his
own account, provided, of course, that sufficient funds are made available by
the Owner for the performance of the Manager's responsibilities.

court costs incurred in connection with the enforcement of this indemnity or
otherwise), arising out of the negligence, fraud or any willful act or omission
of the Manager, or any of its officers, directors, agents or employees, in
connection with this Agreement or the Manager's services or work hereunder,
whether within or beyond the scope of its duties or authority hereunder.

fraud or willful act of the Manager, its officers, directors, agents and
employees, and (ii) the negligence, fraud or any willful act or omission of the
Owner and its partners and their respective officers, directors and employees.

          ---------------------------------------------------              
acknowledges that the Manager's duties and responsibilities hereunder with
respect to the development and construction of the Project consist only in
managing, supervising, and coordinating the planning, design, construction and
completion of the Project and the performance of the other Development Functions
in accordance with the terms of this Agreement; that the Manager is not itself
preparing any architectural or engineering plans, designs, or specifications or
performing any construction required for the development or completion of the
Project; that the Manager is not a guarantor or insurer of any work to be
performed by any other party in connection with the planning, design,
construction, and completion of the Project; and that the Manager is not
responsible for, and will not be liable for, any work, act, omission,
negligence, gross negligence, or intentional misconduct of any other party
employed by the Owner or performing work for the Owner in connection with the
Project.

     9.7  Ownership of Information and Materials.  The Owner shall have the

the Manager in performing its services, to hold in confidence and not to use or
disclose to others any confidential or proprietary information of the Owner
which is heretofore or hereafter disclosed to the Manager or any such persons
and which is designated by the Owner as confidential and proprietary, including

which may come within the knowledge of the Manager or any such persons in the
performance of, or as a result of, its services, except where (i) the Owner
specifically authorizes the Manager to disclose any of the foregoing to others
or such disclosure reasonably results from the performance of the Manager's
duties hereunder, or (ii) such written data or information shall have
theretofore been made publicly available by parties other than the Manager or

     and discharges such employee).

monetary default, such longer period of time as may be needed in the exercise by
the Owner of due diligence to effect a cure of any such non-monetary default),

collection) and of performance. The liability of Guarantor is coextensive with
that of Manager and also joint and several and this Guaranty shall be
enforceable against Guarantor without the necessity of any suit or proceeding on
Owner's part of any kind or nature whatsoever against Manager and without the
necessity of any notice of non-payment, non-performance or non-observance or of
any notice of acceptance of this Guaranty or of any other notice or demand to
which Guarantor might otherwise be entitled, all of which Guarantor hereby
expressly waives. Guarantor hereby expressly agrees that the validity of this
Guaranty and the obligations of Guarantor hereunder shall in no way be
terminated, affected, diminished or impaired by reason of (a) the assertion or
the failure to assert by Owner against Manager of any of the rights or remedies
reserved by Owner pursuant to the terms, covenants and conditions of the
Agreement, or (b) any non-liability of Manager under the Agreement due to
insolvency, discharge in bankruptcy or any other defense of a similar nature.

          This Guaranty shall be a continuing guaranty, and the liability of
Guarantor hereunder shall in no way be affected, released or diminished by
reason of (a) any assignment, renewal, modification, amendment or extension of
the Agreement, or (b) any modification or waiver of or change in any of the
terms, covenants and conditions of the Agreement by Owner and Manager, or (c)
any extension of time that may be granted by Owner to Manager, or (d) any
consent, release, indulgence or other action, inaction or omission under or in
respect of the Agreement, or (e) any dealings or transactions or matter or thing
occurring between Owner and Manager, or (f) any bankruptcy, insolvency,
reorganization, liquidation, arrangement, assignment for the benefit 

                                      -1-

of creditors, receivership, trusteeship or similar proceeding affecting Manager,
whether or not notice thereof or of any thereof is given to Guarantor.

          Should Owner be obligated by any bankruptcy or other law to repay to
Manager or to Guarantor or to any trustee, receiver or other representative of
either of them, any amounts previously paid, this Guaranty shall be reinstated
in the amount of such repayments. Owner shall not be required to litigate or
otherwise dispute its obligations to make such repayments if it in good faith
believes that such obligation exists.

          No delay on the part of Owner in exercising any right, power or
privilege under this Guaranty or failure to exercise the same shall operate as a
waiver of or otherwise affect any such right, power or privilege, nor shall any
single or partial exercise thereof preclude any other or further exercise
thereof or the exercise of any other right, power or privilege.

          No waiver or modification of any provision of this Guaranty nor any
termination of this Guaranty shall be effective unless in writing, signed by
Owner; nor shall any such waiver be applicable except in the specific instance
for which given.

          All of Owner's rights and remedies under the Agreement and under this
Guaranty, now or hereafter existing at law or in equity or by statute or
otherwise, are intended to be distinct, separate and cumulative and no exercise
or partial exercise of any such right or remedy therein or herein mentioned is
intended to be in exclusion of or a waiver of any of the others.

          Guarantor agrees that whenever at any time or from time to time
Guarantor shall make any payment to Owner or perform or fulfill any term,
covenant or condition hereunder on account of the liability of Guarantor
hereunder, Guarantor will notify Owner in writing that such payment or
performance, as the case may be, is for such purpose. No such payment or
performance by Guarantor pursuant to any provision hereof shall entitle
Guarantor by subrogation or otherwise to the rights of Owner to any payment by
Manager or out of the property of Manager, except after payment of all sums or
fulfillment of all covenants, terms, conditions or agreements to be paid or
performed by Manager.

          Without regard to principles of conflicts of laws, the validity,
interpretation, performance and enforcement of this Guaranty shall be governed
by and construed in accordance with the internal laws of the State of Georgia.

    1.2  Verification of Rentable Square Feet of Premises and Building.  For
         -------------------------------------------------------------      
purposes of this Lease, "rentable square feet" shall be calculated in accordance
with BOMA definition American National Standard Z65.1 - 1980 as reaffirmed in
1989.  The rentable square feet of the Premises and Building are subject to
verification and audit which shall be completed by Tenant's and Landlord's
planners and designers prior to the occupancy of the Premises.  In the event
that such planners/designers determine that the amounts thereof are different
from those set forth in this Lease, any amounts, percentages and figures
appearing or referred to in this Lease which are based on the square footage of
the Building shall be modified in accordance with such determination.  If such
determination is made, it will be confirmed in writing by Landlord and Tenant.

    1.3  Construction and Delivery of the Building and Premises.  Landlord will
         ------------------------------------------------------                
construct and deliver to Tenant on the Lease Commencement Date a two (2) story,
concrete tilt-up, high performance glass Building and parking, landscaping,
lighting and access routes to adjacent public streets ("Common Area
Improvements") on the Real Property in accordance with the Work  Letter and in
compliance with all Laws including without limitation the Americans with
Disabilities Act, Hazardous Materials Laws and all seismic Laws. The Building
will contain approximately 150,000 

                                       1

                                  ----------

    2.1  Initial Term.  The terms and provisions of this Lease shall be
         ------------                                                  
effective as of the date of this Lease except for the provisions of this Lease
relating to the payment of Rent.  The term of this Lease and any validly
exercised option (the "Lease Term") shall be as set forth in Section 7.1 of the
Summary and Section 2.2 below and shall commence on the date (the "Lease
Commencement Date") set forth in Section 7.2 of the Summary (subject, however,
to the terms of Section 12 of the Work Letter), and shall terminate on the date
(the "Lease Expiration Date") set forth in Section 7.3 of the Summary, unless
this Lease is sooner terminated or extended as hereinafter provided.  For
purposes of this Lease, the term "Lease Year" shall mean each consecutive twelve
(12) month period during the Lease Term.  At any time within six (6) months
following the Lease Commencement Date, Landlord may deliver to Tenant a notice
of Lease Term dates in the form as set forth in Exhibit C, attached hereto,
                                                ---------                  
which notice Tenant shall execute and return to Landlord within ten (10)
business days of receipt thereof (provided that if said notice is not factually
correct, Tenant shall make any necessary revisions prior to returning such
notice to Landlord).  Notwithstanding the definition of the Lease Commencement
Date for the Premises set forth in Section 7.2 of the Summary, if Tenant
commences business operations from any portion of the Premises prior to the
occurrence of the Lease Commencement Date (the "Pre-Occupancy Space(C)"), all of
the terms and conditions of this Lease shall apply to that portion of the
Premises containing the Pre-Occupancy Space, except that Tenant shall have no
obligation to pay Rent during the period commencing on the date Tenant commences
business operations from the applicable Pre-Occupancy Space and continuing until
the Lease Commencement Date (the "Pre-Occupancy Period(C)").  For purposes of
the immediately preceding sentence, Tenant will not be deemed to have "commenced
business operations" if Tenant has entered the Building for the purpose of
performing its work of construction in the Premises; rather, the "commencement
of business operations" will occur when Tenant is conducting business from the
Premises in its normal course with one or more employees.  At such time as the
Lease Commencement Date occurs, and Tenant has relocated its business operation
from the building located at 15253 Bake Parkway, Irvine, California, into the
Premises, the lease and guarantee thereof shall cease with respect to the former
premises pursuant to a Lease Termination Agreement, in the form attached hereto
as Exhibit D which will be executed concurrently herewith.  Tenant shall have
   ---------                                                                 
the right to commence business operations from any portion of the Premises
during the Pre-Occupancy Period, provided that (i) Tenant shall give Landlord at
least ten (10) days prior notice of any such use of the Premises, and (ii) a
certificate of occupancy or its equivalent permitting occupancy shall have been
issued by the appropriate governmental authorities for the Pre-Occupancy Space.

    2.2  Option Terms.
         ------------ 

         2.2.1  Option Rights.  Landlord hereby grants Tenant two (2) options to
                -------------                                                   
extend the Lease Term for all and not less than all of the Premises for a period
of five (5) years each (the "Option Terms"), which option shall be exercisable
only by written notice delivered by Tenant to Landlord 

                                       2
<PAGE>
 
as provided below, provided that, as of the date of delivery of each of such
notices there is not an outstanding Event of Default by Tenant. Upon the proper
exercise of an option to extend, the Lease Term, as it then applies to the
Premises, shall be extended for a period of five (5) years. The rights contained
in this Section 2.2 may only be exercised by Tenant, its "Affiliates" (as
defined in Section 14.5 below) or an assignee of Tenant to whom an assignment of
this Lease has been made in accordance with Article 14 (and not any sublessee or
other transferee of Tenant's interest in this Lease).

         2.2.2  Option Rent.
                ----------- 

                 2.2.2.1 Rent.  The Base Rent payable by Tenant during the
                         ----
Option Term (the "Option Rent") shall be equal to ninety-five percent (95%) of
the face or stated rental rate, at which, as of the commencement of the Option
Term, tenants are leasing non-expansion, non-affiliated, non-sublease, non-
encumbered, non-equity space comparable in size, location and quality to the
Premises for a term of five (5) years, which comparable space is located in
other comparable buildings and building projects located in the Lake Forest and
Irvine area of Southern California, of similar age, location and quality of
initial construction (the "Comparable Buildings") taking into consideration, and
accounting for any relevant differences in all or any of the following to the
extent applicable:

                         (a) Use, location, height, size and/or floor level(s)
    of the space in question;

                         (b) The time the particular rental rate under
    consideration was agreed upon and became or is to become effective;

                         (c) Abatement or free rent provisions reflecting free
    rent (with respect to base rental, operating expenses, real estate taxes
    and/or parking charges) or absence thereof during any period of the lease
    term, except as set forth below;

                         (d) Inclusion (or absence) of parking charges in
    rental, and/or, subject to the terms of Article 28, below, the extent of
    associated parking rights and the cost thereof and the amount of parking
    available for use by the tenant;

                         (e) Lease takeovers/assumptions;

                         (f) Relocation/moving allowances;

                         (g) Space planning allowances;

                         (h) Tenant improvement, refurbishment and/or
    repainting allowances;

                         (i) Any other concessions or inducements;

                         (j) The base year or expense-stop, if any, applicable
    to such comparable space;

                                       3
<PAGE>
 
                         (k)  Any other adjustments (including by way of
    Consumer Price Index or other indexes) to base rental;

                         (l)  The manner and method of calculating rentable
    area; and

                         (m)  Term of lease.

          While Tenant shall continue to be obligated to pay Direct Expenses in
accordance with Article 4 of this Lease during each Option Term, the amount of
Base Rent shall be adjusted, if necessary, to reflect such obligation by Tenant
to pay Direct Expenses vis-a-vis comparable transactions.

          Notwithstanding the foregoing, however, in calculating the Option
Rent, (i) no consideration shall be given to (a) any period of rent abatement
given such tenants in connection with the construction of improvements in such
comparable space, (b) the presence or absence of a brokerage commission in
connection with Tenant's exercise of the Option Term, or in connection with such
comparable deals and (ii) consideration shall be given to the fixed rental
increase specified in Section 2.2.2.3 below.

          2.2.2.2   Concessions.  The arbitrator shall inform Landlord and
                    -----------                                           
Tenant of the amount of any concessions to be granted Tenant pursuant to items
(e) through (i), above (the "Option Concessions") as a component of the Option
Rent. Landlord or Tenant may make a binding election that, in lieu of granting
any or a portion the Option Concessions to Tenant in the form and at the times
as granted in the comparable transactions, the rental rate component of the
Option Rent shall be adjusted to be an effective rental rate which takes into
consideration the total present dollar value (with interest at the Interest
Rate) of that portion of such Option Concessions which Landlord or Tenant has
elected not be granted to Tenant (in which case that portion of the Option
Concessions evidenced in the effective rental rate shall not be granted to
Tenant).

          2.2.2.3   Base Rent Adjustment.  The Base Rent as determined at the
                    --------------------                                     
beginning of each Option Term shall be adjusted upward during the Option Term at
the beginning of the 24th and 48th month of each Option Term by an amount equal
to six percent (6%) of the Base Rent payable in the immediately preceding
period.

         2.2.3  Exercise of Option.  The options contained in this Section 2.2
                ------------------                                            
shall be exercised by Tenant, if at all, and only in the following manner:  (i)
Tenant shall deliver written notice to Landlord (the "Option Interest Notice")
not more than nineteen (19) months or less than fifteen (15) months prior to the
expiration of the initial Lease Term or the initial Option Term, as applicable,
stating that Tenant is interested in exercising its option, and within thirty
(30) days after receipt of Tenant's Option Interest Notice Landlord shall
deliver to Tenant notice containing Landlord's proposed Option Rent; (ii)
Landlord and Tenant shall thereafter use their reasonable good-faith efforts to
agree upon the Option Rent before the first day of the thirteenth (13th) month
prior to the expiration of the initial Lease Term or the initial Option Term, as
applicable; (iii) whether or not Tenant has previously delivered an Option
Interest Notice to Landlord, not later than the first day of the thirteenth
(13th) month prior to the expiration of the initial Lease Term or the initial
Option Term, 

                                       4
<PAGE>
 
as applicable, Tenant may, by notice to Landlord, request Landlord's
determination of the Option Rent which Landlord would submit to arbitration, if
arbitration were to occur under Section 2.2.4, below, and within ten (10)
business days of such request, Landlord and Tenant shall each concurrently
deliver to the other the determinations of the Option Rent that each would
submit to arbitration if arbitration were to occur under Section 2.2.4, below
(the "Arbitration Option Rent"); and (iv) if Tenant wishes to exercise its
option Tenant shall, on or before the date occurring twelve (12) months prior to
the expiration of the initial Lease Term or the initial Option Term, as
applicable, exercise the option by delivering written notice thereof to Landlord
and upon, and concurrent with, such exercise Tenant may, at its option, elect to
arbitrate the Option Rent, in which case the parties shall follow the procedure,
and the Option Rent shall be determined, as set forth in Section 2.2.4, below.
Notwithstanding the foregoing, if Tenant fails to deliver the Option Interest
Notice, Tenant may nevertheless, on or before the date which is twelve (12)
months prior to the expiration of the initial Lease Term or the initial Option
Term, as applicable, deliver to Landlord notice that Tenant is thereby
irrevocably electing to exercise its option to extend the Lease Term, in which
case the Option Rent shall be determined pursuant to the procedure set forth in
Section 2.2.4, below.

     2.2.4  Determination of Option Rent.  In the event Tenant timely elects
            ----------------------------                                    
to arbitrate the Option Rent, pursuant to the terms of Section 2.2.3, Landlord
and Tenant shall attempt to agree upon the Option Rent using their best good-
faith efforts.  If Landlord and Tenant fail to reach agreement within fifteen
(15) days following Tenant's election to arbitrate (the "Outside Agreement
Date"), then each party shall make a separate determination of the Option Rent
within ten (10) business days after the Outside Agreement Date, and such
determinations (which for purposes of this Section 2.2.4 shall also be known as
"Arbitration Option Rents") shall be submitted to arbitration in accordance with
Sections 2.2.4.1 through 2.2.4.7, below; provided, however, that if the
Arbitration Option Rents have been established pursuant to Section 2.2.3, then
such Arbitration Option Rents shall be submitted to arbitration in accordance
with Sections 2.2.4.1 through 2.2.4.7, below.

            2.2.4.1   Landlord and Tenant shall each appoint one arbitrator who
shall by profession be a real estate broker or appraiser who shall have been
active over the five (5) year period ending on the date of such appointment in
the leasing (or appraisal, as the case may be) of Lake Forest, California-area
commercial buildings such as the Comparable Buildings, exclusive of any broker
from any brokerage firm currently representing (or who had previously
represented within the preceding two (2) year period) either party or any
affiliate thereof.  The determination of the arbitrators shall be limited solely
to the issue of whether Landlord's or Tenant's submitted Arbitration Option Rent
is the closest to the actual Option Rent as determined by the arbitrators,
taking into account the requirements of Section 2.2.2.  Each such arbitrator
shall be appointed within fifteen (15) days after the applicable Outside
Agreement Date.

            2.2.4.2   The two arbitrators so appointed shall within fifteen (15)
days of the date of the appointment of the last appointed arbitrator agree upon
and appoint a third arbitrator who shall be qualified under the same criteria
set forth hereinabove for qualification of the initial two arbitrators.

            2.2.4.3   The three arbitrators shall within thirty (30) days of the
appointment of the third arbitrator reach a decision as to whether the parties
shall use Landlord's or Tenant's submitted Arbitration Option Rent and shall
notify Landlord and Tenant thereof.

          2.2.4.4   Subject to the following provisions, the decision of the
majority of the three arbitrators shall be binding upon Landlord and Tenant.

          2.2.4.5   If either Landlord or Tenant fails to appoint an arbitrator
within 15 days after the applicable Outside Agreement Date, the arbitrator
appointed by one of them shall reach a decision, notify Landlord and Tenant
thereof, and, subject to the provisions of this Section 2.2.4, such arbitrator's
decision shall be binding upon Landlord and Tenant.

          2.2.4.6   If the two arbitrators fail to agree upon and appoint a
third arbitrator, or both parties fail to appoint an arbitrator, then the
appointment of the third arbitrator or any arbitrator shall be dismissed and the
matter to be decided shall be forthwith submitted to arbitration under the
provisions of the American Arbitration Association, but subject to the
instruction set forth in this Section 2.2.4.

          2.2.4.7   The cost of the arbitration shall be paid by the party
whose submitted Arbitration Option Rent is not selected.

     Commencing on the Lease Commencement Date, Tenant shall pay, without notice
or demand, to Landlord or Landlord's agent at the address set forth in Section 3
of the Summary, or at such other place in the continental United States as
Landlord may from time to time designate in writing, by check drawn upon a bank
located in the United States of America (for currency which, at the time of
payment, is legal tender for private or public debts in the United States of
America), base rent ("Base Rent") as set forth in Section 8 of the Summary,
payable in equal monthly installments as set forth in Section 8 of the Summary
in advance on or before the first day of each and every month during the Lease
Term, without any setoff or deduction whatsoever, except as otherwise expressly
provided in this Lease.  If any rental payment date (including the Lease
Commencement Date) falls on a day of the month other than the first day of such
month or if any rental payment is for a period which is shorter than one month,
then the rental for any such fractional month shall be a proportionate amount of
a full calendar month's rental based on the proportion that the number of days
in such fractional month bears to the number of days in the calendar month
during which such fractional month occurs.  All other payments or adjustments
required to be made under the terms of this Lease that require proration on a
time basis shall be prorated on the same basis.

the Real Property taxes and insurance, (which Tenant may elect so to do) and pay
such expenses on a direct basis (subject to a review thereof by Landlord on a
semi-annual basis, with Landlord reserving the right to reinstate itself in the

performing its management responsibilities in a manner which appropriately
preserves the value of the Real Property), Tenant shall pay as additional rent
for each "Expense Year," as that term is defined in Section 4.2.4 of this Lease,
all of the annual "Direct Expenses," as that term is defined in Section 4.2.2 of
this Lease.  Such additional rent, together with any and all other amounts
payable by Tenant to Landlord pursuant to the terms of this Lease, shall be
hereinafter collectively referred to as the "Additional Rent."  The Base Rent
and Additional Rent are herein collectively referred to as the "Rent."  All
amounts payable under this Article 4 as Additional Rent shall be payable for the
same periods and in the same manner and place as the Base Rent.  Without
limitation on other obligations which shall survive the expiration of the Lease
Term, the obligations of Tenant and Landlord provided for in this Article 4
shall survive the expiration of the Lease Term.

    4.2  Definitions.  As used in this Article 4, the following terms shall have
         -----------                                                            
the meanings hereinafter set forth:
 
         4.2.1  "Calendar Year" shall mean each calendar year in which any
portion of the Lease Term falls, through and including the calendar year in
which the Lease Term expires.

         4.2.2  "Direct Expenses" shall mean "Operating Expenses" and "Tax
Expenses."

         4.2.3  "Expense Year" shall mean each Calendar Year.

         4.2.4  "Operating Expenses" shall mean all direct and indirect costs,
expenses, and assessments charged to the Real Property with respect to its
efficient and economical operation (including insurance premiums for the
insurance policies described in Sections 10.2, 10.3 and 10.5 below), management,
use, maintenance and repair, other than those which are set forth in Section 6.1
below.  Operating Expenses shall not include those items set forth on the
Operating Expense Exclusion list attached hereto as Exhibit H.
                                                    --------- 

         4.2.5  "Tax Expenses" shall mean all federal, state, county, or local
governmental or municipal taxes, fees or other impositions of every kind and
nature, whether general, special, ordinary or extraordinary, (including, without
limitation, real estate taxes, general and special assessments, transit taxes,
leasehold taxes or taxes based upon the receipt of rent, including gross
receipts or sales taxes applicable to the receipt of rent, unless required to be
paid by Tenant, personal property taxes imposed upon the fixtures, machinery,
equipment, apparatus, systems and equipment, appurtenances, furniture and other
personal property used in connection with the Building), which are allocable to
a particular Expense Year (without regard to any different fiscal year used by
such governmental or municipal authority) in connection with the ownership,
leasing and operation of the Real Property or Landlord's interest therein.

                4.2.5.1   Tax Expenses shall include, without limitation:

                (i) Any governmental tax on Landlord's rent, right to rent or
    other income from the Real Property or as against Landlord's business of
    leasing any of the Real Property;

                                       7
<PAGE>
 
              (ii)     Any assessment, tax, fee, levy or charge in addition to,
    or in substitution, partially or totally, of any assessment, tax, fee, levy
    or charge previously included as of the date hereof within the definition of
    real property tax, it being acknowledged by Tenant and Landlord that
    Proposition 13 was adopted by the voters of the State of California in the
    June 1978 election ("Proposition 13") and that assessments, taxes, fees,
    levies and charges may be imposed by governmental agencies for such services
    as fire protection, street, sidewalk and road maintenance, refuse removal
    and for other governmental services formerly provided without charge to
    property owners or occupants, and, in further recognition of the decrease in
    the level and quality of governmental services and amenities as a result of
    Proposition 13, Tax Expenses shall also include any governmental assessments
    or contribution towards a governmental cost-sharing agreement for the
    purpose of augmenting or improving the quality of services and amenities
    normally provided by governmental agencies. It is the intention of Tenant
    and Landlord that all such new and increased assessments, taxes, fees,
    levies and charges and all similar assessments, taxes, fees, levies and
    charges be included within the definition of Tax Expenses for purposes of
    this Lease;

              (iii)    Any governmental assessment, tax, fee, levy, or charge
    allocable to or measured by the area of the Premises or the rent payable
    hereunder, including, without limitation, any gross income tax with respect
    to the receipt of such rent; and

              (iv)     Any assessment, tax, fee, levy or charge, upon this
    transaction or any document to which Tenant is a party, creating or
    transferring an interest or an estate in the Premises.

              4.2.5.2   With respect to any assessment otherwise includable
within Tax Expenses that may be levied against or upon the Real Property and
that under the laws then in force may be evidenced by improvement or other
bonds, or may be paid in annual installments, there shall be included within the
definition of Tax Expenses with respect to any tax fiscal year only the amount
currently payable on such bonds, including interest, for such tax fiscal year,
or the current annual installment for such tax fiscal year, in each case
utilizing the payment or installment method which will minimize the amount of
Tax Expenses.

              4.2.5.3   If the method of taxation of real estate prevailing at
the time of execution hereof shall be, or has been, altered so as to cause the
whole or any part of the taxes now, hereafter or heretofore levied, assessed or
imposed on real estate to be levied, assessed, or imposed upon Landlord, wholly
or partially, as a capital levy or otherwise, or on or measured by the rents
received therefrom, then such new or altered taxes attributable to the Real
Property shall be included within the term "Tax Expenses" except that the same
shall not include any enhancement of said tax attributable to other income of
Landlord.

              4.2.5.4   Subject to the provisions of this Lease, any reasonable
expenses reasonably incurred by Landlord in attempting to protest, reduce or
minimize Tax Expenses shall be included in Tax Expenses in the Expense Year such
expenses are paid.

              4.2.5.5   Tax refunds shall be deducted from Tax Expenses in the
Expense Year to which the same are attributable.

          4.2.5.6   Subject to the terms of this Section 4.2.5, if Tax Expenses
for any period during the Lease Term or any extension thereof are increased
after payment thereof by Landlord for any reason, including, without limitation,
error or reassessment by applicable governmental or municipal authorities, such
increase shall be included in Tax Expenses in the Expense Year to which such
increase is attributable, and Tenant shall pay Landlord Tenant's Share of such
increased Tax Expenses to the extent there exists an Excess for such Expense
Year.

          4.2.5.7   Notwithstanding anything to the contrary contained in this
Lease, there shall be excluded from Tax Expenses (i) all excess profits taxes,
franchise taxes, gift taxes, capital stock taxes, inheritance and succession
taxes, estate taxes, federal and state income taxes, and other taxes to the
extent applicable to Landlord's general or net income (as opposed to rents,
receipts or income attributable to operations at the Building), (ii) any items
included as Operating Expenses, and (iii) any items paid by Tenant under Section
4.4 of this Lease.

          4.2.5.8   Despite any other provision of this Lease, if during the
initial Lease Term, any sale or change in ownership of the Premises is
consummated and, as a result, all or part of the Premises is reassessed
("Reassessment") for real estate tax purposes by the appropriate government
authority under the terms of Proposition 13 (as adopted by the voters of the
State of California in the June 1978 election), the terms of this subsection
4.2.5.8 shall apply.

                    (a)  For purposes of this subsection 4.2.5.8, the term "Tax
    increase" shall mean that portion of the Tax Expenses, as calculated
    immediately following the Reassessment, that is attributable solely to the
    Reassessment.  Accordingly, a Tax increase shall not include any portion of
    the Tax Expenses, as calculated immediately following the Reassessment, that
    is:

                              (1)  Attributable to the initial assessment of the
    value of the Premises, or the tenant improvements located in the Premises;

                              (2)  Attributable to a one-time transfer of
    ownership within thirty (30) days of the Lease Commencement Date by Landlord
    to an affiliate (as that term is defined in Section 14.5) of Landlord, at a
    purchase price no greater than One Hundred Thousand Dollars ($100,000.00) in
    excess of the Total Project Costs; or

                              (3)  Attributable to the annual inflationary
    increase in real estate taxes.

                    (b)  During the Initial Lease Term, Tenant shall not be
    obligated to pay any portion of the Tax increase relating to a Reassessment
    occurring during the Initial Lease Term.

    4.3  Calculation and Payment of Additional Rent.
         ------------------------------------------ 

         4.3.1  Payment Direct Expenses.  For any Expense Year ending or
                -----------------------                                 
commencing within the Lease Term, Tenant shall pay directly, or, as applicable,
to Landlord, in the manner set forth in 

                                       9
<PAGE>
 
Section 4.3.2, below, and as Additional Rent, an amount equal to the Direct
Expenses for such Expense Year.

         4.3.2  Statement of Actual Direct Expenses and Payment by Tenant.
                ---------------------------------------------------------  
Landlord shall endeavor to give to Tenant on or before the first day of April
(and must deliver by July 1) following the end of each Expense Year, a statement
(the "Statement"), certified by an appropriate official of Landlord or
independent certified public accountant, which shall state that portion of the
Direct Expenses not directly paid by Tenant, and which portion is  allocable to
such preceding Expense Year.  Tenant shall pay, within thirty (30) days after
receipt of the Statement, the full amount of the Landlord-billed Direct Expenses
for such Expense Year, less the amounts, if any, paid during such Expense Year
as an "Estimated Payment," as that term is defined in Section 4.3.3, below.  In
the event the amount paid by Tenant as an Estimated Payment exceeds the amount
of the Landlord-billed Direct Expenses, Tenant shall receive a credit against
the next payment of Additional Rent due under this Lease.  The failure of
Landlord to timely furnish the Statement for any Expense Year shall not
prejudice either party from enforcing its rights under this Article 4; provided,
however, that except with regard to the recalculation of those items of Direct
Expenses which are not under Landlord's reasonable control, specifically
including Tax Expenses and public utility charges, Landlord shall not be
permitted to add to Direct Expenses or bill for the first time any portion of
Direct Expenses more than two (2) years following the last day of the Expense
Year to which such Direct Expenses relate.

         Subject to the provisions of this Lease, even though the Lease Term has
expired and Tenant has vacated the Premises, when the final determination is
made of the Direct Expenses for the Expense Year in which this Lease terminates,
(i) if Tenant has not paid all of the Direct Expenses for such Expense Year,
Tenant shall pay to Landlord, within thirty (30) days after receipt of a
reasonably detailed bill therefor, an amount as calculated pursuant to the
provisions of Section 4.3.1 of this Lease, and (ii) if Tenant has made an
overpayment of Additional Rent, Landlord shall pay the same to Tenant within
thirty (30) days of such determination.  The provisions of this Section 4.3.2
shall survive the expiration or earlier termination of the Lease Term.

         4.3.3  Statement of Estimated Direct Expenses.  In addition, Landlord
                --------------------------------------                        
shall endeavor to give Tenant a yearly expense estimate statement (the "Estimate
Statement") within one hundred twenty (120) days and no later than one hundred
eighty (180) days of the commencement of each Expense Year, which Estimate
Statement shall set forth Landlord's reasonable estimate (the "Estimate") of
what the total amount of Landlord-billed Direct Expenses for the then-current
Expense Year shall be (the "Estimated Payment").  The failure of Landlord to
timely furnish the Estimate Statement for any Expense Year shall not preclude
Landlord from enforcing its rights to collect any Estimated Payment under this
Article 4.  Tenant shall pay, within thirty (30) days of Tenant's receipt of
such Estimate Statement, a fraction of the Estimated Payment for the then-
current Expense Year (reduced by any amounts paid pursuant to the last sentence
of this Section 4.3.3).  Such fraction shall have as its numerator the number of
months which have elapsed in such current Expense Year to the month of such
payment, both months inclusive, and shall have twelve (12) as its denominator.
Until a new Estimate Statement is furnished, Tenant shall pay monthly, with the
monthly Base Rent installments, an amount equal to one-twelfth (1/12) of the
total Estimated Payment set forth in the previous Estimate Statement delivered
by Landlord to Tenant.

    4.4  Taxes and Other Charges for Which Tenant Is Directly Responsible.
         ----------------------------------------------------------------  
Tenant shall reimburse Landlord, within thirty (30) days of Tenant's receipt of
a reasonably detailed written demand accompanied by appropriate supporting
evidence (but in any case prior to delinquency), for any and all taxes or
assessments required to be paid by Landlord (except to the extent included in
Tax Expenses by Landlord), excluding state, local and federal personal or
corporate income taxes measured by the net income of Landlord from all sources
and estate and inheritance taxes, whether or not now customary or within the
contemplation of the parties hereto, when said taxes are required to be paid by
Tenant and said taxes are measured by or reasonably attributable to the cost of
Tenant's equipment, furniture, fixtures and other personal property located in
the Premises, or by the cost of all leasehold improvements made in or to the
Premises by or for Tenant.

    4.5  Landlord's Books and Records; Tenant's Audit Rights.  Tenant or
         ---------------------------------------------------            
Tenant's  authorized representatives (the "Outside Agent") may, after reasonable
notice to Landlord and at reasonable times, examine, inspect, audit, and copy
the records of Landlord regarding each Statement at Landlord's office in the
continental United States during normal business hours within one (1) year after
the furnishing of the Statement.  The Outside Agent shall be a nationally or
regionally recognized firm of certified public accountants and shall be engaged
on a non-contingency fee basis.  Unless Tenant takes written exception to any
item within two (2) years after the furnishing of that Statement, the Statement
shall be considered as final and accepted by Tenant except that Landlord may, at
any time during that two-year period, submit a corrected Statement to Tenant if
Operating Expenses and Tax Expenses on the original Statement were overstated or
understated.

    The payment of the amounts shown on the Statement by Tenant shall not
preclude Tenant from questioning the correctness of any item of the Statement
subject to the rights in this Section 4.5.  Tenant and/or its Outside Agent
shall have the right, at Tenant's cost and on no less than ten (10) days' prior
written notice to Landlord and during Landlord's normal business hours, to audit
Landlord's records regarding Operating Expenses and Tax Expenses.  Such an Audit
shall be performed in Landlord's office in the continental United States.

    To facilitate an audit by Tenant, Landlord shall keep its books and records
applicable to Operating Expenses and Tax Expenses available to Tenant on a
reasonable basis for the longer of (a) two (2) years after the Lease Expiration
Date or (b) one (1) year after the resolution of any dispute concerning
Operating Expenses and Tax Expenses.  Any audit of Operating Expenses and Tax
Expenses for any calendar year must be begun within two (2) years after
Landlord's delivery of the Statement for that year, or the right to audit
Operating Expenses and Tax Expenses for that year shall be deemed waived.

    Tenant agrees diligently to pursue and complete (or to drop) any audit begun
by Tenant, and Landlord agrees it shall not unreasonably interfere with the
execution of Tenant's audit rights.  Tenant shall bear all fees and costs of the
audit, unless the parties determine that Operating Expenses and Tax Expenses
taken as a whole for any calendar year were overstated by four percent (4%) or
more.  In that event, Landlord shall pay for the reasonable costs of that audit.
Pending resolution of any disputes over Operating Expenses and Tax Expenses,
Tenant shall pay to Landlord any Additional Rent alleged to be due from Tenant
as reflected on Landlord's Statement or any invoice issued on the basis of
Landlord's Statement.

Landlord.  This Lease is subject in all respects to the CC&Rs and the Bylaws of
the "Associations" established under the CC&Rs.  Tenant shall comply with the
recorded covenants, conditions and restrictions now or (so long as no negative
impact affects the Premises or Tenant's occupancy of the Premises) hereafter
affecting the Premises and with all reasonable rules adopted from time to time
by the Associations established under the CC&Rs.  Tenant shall not use or allow
another person or entity to use any part of the Premises for the storage,
treatment, manufacture or sale of "Hazardous Material" as that term is defined
in Section 29.24 of this Lease, other than as may be permitted by, and used in
accordance with, all applicable laws, regulations and ordinances pertaining to
the Premises.

    5.3  Transportation Management. Tenant agrees that Tenant shall, at Tenant's

sole cost and expense, comply with the Night-Time Truck Management Plan attached

          ---------                                                    
monitoring programs, transportation performance standards and transportation
management plans for the Premises implemented by the Associations established
under the CC&Rs, as the same may be amended from time to time.  Tenant further
agrees to cooperate with the annual audits required under the Night-Time Truck
Management Plan.  Tenant's failure to comply with the Night-Time Truck
Management Plan shall constitute a material default under this Lease.

         -------------------                                               
below, Tenant agrees that Landlord shall not be liable for damages, by abatement
of Rent or otherwise, for failure of Tenant to receive any service (including
telephone and telecommunication services) or utility for any reason whatsoever,
or for any diminution in the quality or quantity thereof, and such failures or
delays or diminution shall never be deemed to constitute an eviction or
disturbance of Tenant's use and possession of the Premises or relieve Tenant
from paying Rent or performing any of its obligations under this Lease, except
as provided in this Lease to the contrary.  Furthermore, Landlord shall not be
liable under any circumstances for a loss of, or injury to, property or for
injury to, or interference with, Tenant's business, including, without
limitation, loss of profits, however occurring, through or in connection with or
incidental to any such failure of Tenant to receive any services or utilities.

    6.3  No Obligation.  Subject to Landlord's completion of Landlord's Work as
         -------------                                                         
specified in Exhibit B, Landlord shall have no obligation to provide any
             ---------                                                  
services or utilities to the Premises including, but not limited to heating,
ventilation and air-conditioning, electricity, water, telephone, janitorial and
security services, window washing and landscaping services.

    6.4  Abatement Conditions.
         -------------------- 

         6.4.1  Notwithstanding anything to the contrary contained in this
Lease, if Tenant is prevented from using all or a portion of the Premises,
including the parking areas thereon, for its normal business operations, and
Tenant does not, in fact, use all or a portion of the Premises for a period of
three (3) consecutive business days or more or for seven (7) business days in a
Calendar Year, (i) due to any service or utility, including HVAC, electricity or
water (collectively, the "Essential Services"), not being provided to the
Premises, or portion thereof, (ii) because of the presence, in a form or
concentration in violation of applicable law then in effect, of Hazardous
Materials regarded as unhealthful under applicable regulations then in effect in
or about the Premises (which Hazardous Materials were not brought onto the
Premises by Tenant or Tenant's employees, agents, or licensees), (iii) due to a
"Service Interruption" (meaning an interruption in services as described in
Section 6.2 above which is not otherwise covered by Article 11), or (iv) because
Tenant does not have access to the Building, the Premises, or portion thereof,
and such prevention from use is not caused by Tenant and/or its employees,
licensees, contractors or agents, or if caused by Tenant and/or its employees,
licensees, contractors or agents, such prevention from use is covered by
insurance required to be carried by Landlord under the provisions of Article 10
of this Lease, the following Sections 6.4.1.1 and 6.4.1.2 shall apply (the
conditions set forth in items (i) through (iv), above, to be known as an
"Abatement Condition").  Notwithstanding the foregoing, this Section 6.4 shall
not apply to the damage or destruction of the Premises or the parking area
pursuant to Article 11, or to the condemnation of the Premises pursuant to
Article 13.  To the extent an Abatement Condition affects only a portion of the
Premises, and such portion is a material portion of the Premises, and Tenant is
not reasonably able to conduct its business from the remaining portion of the
Premises, the Abatement Condition shall be deemed to affect the entire Premises.

                6.4.1.1   Tenant shall promptly deliver to Landlord notice (the
"Cure Notice") of such condition and if Landlord fails to cure such condition
within two (2) business days after delivery to it of the Cure Notice, then Rent
applicable to the affected portion of the Premises shall be abated from the date
which occurred three (3) full business days prior to delivery to Landlord of 

                                       13
<PAGE>
 
the Cure Notice until the date when such failure is cured; provided, however,
that if Tenant has previously paid Rent to Landlord for a period of time
subsequent to the commencement of Tenant's right to abate Rent hereunder, then
Landlord shall, within ten (10) business days following the date of such
abatement, credit to Tenant an amount equivalent to such excess payments against
the sums next due under this Lease, or, if after the expiration or termination
of this Lease, reimburse to Tenant the amount of such excess payments. The right
to abate Rent set forth in this Section 6.4 shall be Tenant's sole and exclusive
Rent Abatement remedy for the occurrence of an Abatement Condition.

               6.4.1.2   If any Abatement Condition (other than an Abatement
Condition caused by a casualty) shall not be cured within ninety (90) days after
Landlord's receipt of the Cure Notice, the Abatement Condition applies to the
entire Premises and Tenant does not use a commercially tenantable portion of the
Premises during a significant portion of the period of the Abatement Condition,
then Tenant, upon notice to Landlord and "Lender" (as that term is defined in
Article 18 hereof) (the "Services Termination Notice") within thirty (30) days
after the expiration of such ninety (90) day period (the "Termination Cure
Period"), may terminate this Lease, which termination shall be deemed effective
upon Tenant's vacation of the entire Premises, but in no event more than two (2)
years after the receipt of the Services Termination Notice by Landlord and
Lender.  Tenant's right to terminate this Lease as a result of a casualty shall
be governed by Article 11 hereof.

        6.4.2  If any governmental entity promulgates or revises any statute,
ordinance, building code, fire code or other code or imposes mandatory controls
on Landlord or the Real Property or any part thereof, relating to the use or
conservation of energy, water, gas, light or electricity or the reduction of
automobile or other emissions or the provision of any other utility or service
provided with respect to this Lease or if Landlord is required to make
alterations to the Building or any other part in order to comply with such
mandatory controls or guidelines (which compliance shall be subject to the terms
of Article 7 of this Lease), then Landlord shall comply with such mandatory
controls or make such alterations to the Building or any other part of the Real
Property related thereto without creating any liability of Landlord to Tenant
under this Lease, provided that the Premises are not thereby rendered
untenantable and provided further that Landlord shall use reasonable efforts to
minimize the impact of such compliance and alterations on Tenant's use and
occupancy of the Premises.  Such compliance and the making of such permitted
alterations shall, except as provided in Section 6.4.1, not entitle Tenant to
any damages, relieve Tenant of the obligation to pay the full Rent reserved
hereunder or constitute or be construed as a constructive or other eviction of
Tenant.

     7.1  Tenant's Obligations.

          7.1.1  Tenant Required Actions.  Subject to the provisions of Section
                 -----------------------                                       
7.2, Articles 11 and 13 and Section 29.29, Tenant shall, at Tenant's sole cost
and expense, operate, keep, and maintain, and as necessary, repair, restore,
replace, and make any capital improvements to (collectively, the "Tenant
Required Actions") (i) the structural portions of the Building (excluding the
structural skeleton of the Building described in Section 7.2 below), including
the ceilings, floor surface, interior walls and wall covering, shafts, stairs,
parking areas, stairwells, elevator cabs, 

                                       14
<PAGE>
 
washrooms, and Building mechanical, electrical and telephone closets
(collectively, "Building Structure"), and (ii) the Building mechanical,
electrical, gas, life safety, plumbing, sprinkler systems, elevators, restrooms,
and heating, ventilation and air-conditioning systems (the "Building Systems"),
in good order and repair and in good and safe working order and condition at all
times during the Lease Term, including any items of the Building Structure or
Building Systems included in the "Tenant Improvements", as that term is defined
in the Work Letter, or "Alterations", as that term is defined in Section 8.1,
below (collectively, the "Tenant Maintenance Items"). All repairs and
maintenance of the Premises by Tenant as required under this Lease shall be
performed in a good and safe manner by contractors and other personnel
reasonably approved by Landlord, and in compliance with the provisions of
Article 8 below. Tenant shall also be obligated to pay, as an Operating Expense,
the following costs: the cost of any capital improvements (A) made by Landlord
which are intended as a labor saving device or to effect other economies in the
operation or maintenance of the Real Property, or any portion thereof, but the
amount Tenant shall pay is limited to the reasonably projected savings
therefrom; or (B) made to all or any portion, or any portion thereof, after the
Lease Commencement Date which are required under any governmental law or
regulation which was not applicable as of the date of commencement of
construction of the Building by Landlord; provided, however, that each such
permitted capital expenditure shall be amortized (including interest on the
unamortized cost) over its useful life as Landlord shall reasonably determine,
provided, however, that Tenant shall not be responsible for such amortization
payments to the extent that the capital expenditure was for an item as to which
Landlord is solely responsible under the provisions of Section 7.2 below.

          7.1.2  Maintenance Contracts.  As a part of Tenant's Required Actions,
                 ---------------------                                          
Tenant shall, at Tenant's sole cost and expense, maintain contracts for the
inspection, maintenance and service of the (i) heating, air conditioning and
ventilation equipment, (ii) boiler, fired or unfired pressure vessels, (iii)
fire sprinkler and/or standpipe and hose or other automatic fire extinguishing
systems, including fire alarm and/or smoke detection, and (iv) electrical
systems.

     7.2  Landlord's Obligations.  It is intended by the parties hereto that
          ----------------------                                            
Landlord have no obligation, in any manner whatsoever, to take any of the Tenant
Required Actions with respect to the Building Systems or Building Structure,
except as set forth in this Section 7.2, below.  It is the intention of the
parties that the terms of this Lease govern the respective obligations of the
parties as to maintenance and repair of the Premises.  Tenant waives the right
to make repairs at the expense of Landlord or to terminate this Lease by reason
of any needed repairs under Sections 1941 and 1942 of the California Civil Code,
or any similar law, statute, or ordinance, now or hereafter in effect.
Notwithstanding the foregoing, during the Lease Term, Landlord shall maintain
and repair the structural skeleton of the Building consisting only of the floor
slabs, foundation, roof structure, roof membrane, exterior walls and exterior
glass and mullions ("Landlord Maintenance Items").  Landlord shall deliver the
Building with all of the Building Structure and Building Systems described in
Section 7.1.1. above in new and first-class working condition and in compliance
with all Laws.  In addition, Landlord shall provide to Tenant a ten (10) year
warranty on the roof of the Building.  Landlord hereby agrees that to the extent
that the Building, the Building Structure or the Building Systems and their
component parts are not constructed in accordance with applicable Laws, or if it
is later discovered the Building, Building Structure or Building Systems have
any defects, Landlord shall at its sole cost and expense, remedy any and all
such portions of the Building or its component parts so long as such non-
compliance is ascertained within one (1) year from Substantial Completion 

                                       15
<PAGE>
 
of the Landlord's Work.. All warranties associated with the Building and any
equipment or systems installed therein shall be assigned on the Lease
Commencement Date to Tenant (such assignment to be on a non-exclusive basis, to
be shared with Landlord, as to Landlord Maintenance Items).

    7.3  Tenant's Right to Make Repairs.  If Tenant provides written notice to
         ------------------------------                                       
Landlord of an event or circumstance which requires the action of Landlord with
respect to the Landlord Maintenance Items and Landlord fails to provide or
commence to provide (and thereafter diligently proceed with such efforts to
completion) such action as required by the terms of this Lease within ten (10)
days after receipt of such written notice (or such lesser period of time as may
be applicable in the event of an emergency), Tenant may proceed to take the
required action upon delivery of an additional five (5) business days notice to
Landlord (or within the applicable and appropriate time period based on an
emergency) specifying that Tenant is taking such required action, and if such
action was required under the terms of this Lease to be taken by Landlord, then
Tenant shall be entitled to prompt reimbursement by Landlord of Tenant's
reasonable and documented costs and expenses in taking such action within thirty
(30) days after receipt by Landlord of an invoice from Tenant which sets forth a
reasonably particularized breakdown of the costs and expenses incurred by Tenant
in connection with taking such action.  In the event Landlord does not reimburse
Tenant for such costs and expenses within thirty (30) days of receipt by
Landlord of such invoice, then interest shall thereafter accrue on such unpaid
amounts at the Interest Rate until such time as payment is made by Landlord.
Tenant may utilize the services of any qualified contractor which normally and
regularly performs similar work in Comparable Buildings.  Further, if Landlord
does not deliver a detailed written objection to Tenant, within thirty (30) days
after receipt of an invoice by Tenant of its costs of taking action which Tenant
claims should have been taken by Landlord, and if such invoice from Tenant sets
forth a reasonably particularized breakdown of its costs and expenses in
connection with taking such action on behalf of Landlord, then Tenant shall be
entitled to deduct from Rent payable by Tenant under this Lease, the amount set
forth in such invoice together with interest at the Interest Rate.  If, however,
Landlord in good faith delivers to Tenant, within thirty (30) days after receipt
of Tenant's invoice, a written objection to the payment of such invoice, setting
forth with reasonable particularity Landlord's reasons for its claim that such
action did not have to be taken by Landlord pursuant to the terms of this Lease
or that the charges are excessive (in which case Landlord shall pay the amount
it contends would not have been excessive), then Tenant shall not be entitled to
such deduction from Rent, but Tenant may proceed to institute legal proceedings
against Landlord to collect the amount set forth in the subject invoice.  If
Tenant receives a non-appealable final judgment against Landlord in connection
with such legal proceedings, Tenant may deduct the amount of the judgment, not
to exceed the amount of the unpaid portion of the relevant invoice, and
reasonable attorneys' fees actually incurred by Tenant, together with interest
thereon at the Interest Rate from the Base Rent next due and owing under this
Lease.

                          CONDITIONS AND ALTERATIONS
                          --------------------------

    8.1  Landlord's Consent to Alterations.  Tenant may, without the need to
         ---------------------------------                                  
obtain the consent or approval of Landlord, make any improvements, alterations,
additions or changes to the Premises (collectively, the "Alterations") desired
by Tenant which do not create a Design Problem, by 

                                       16
<PAGE>
 
providing Landlord with written notice not less than six (6) business days prior
to the commencement thereof. For purposes of this Lease, "Design Problem" shall
mean any alteration, repair, modification, or improvement by Tenant which (a)
materially or adversely affects the Building Systems or Building Structure, (b)
is not in compliance with applicable laws, or (c) affects the exterior
appearance of the Building. Tenant may not make any Alteration which may create
a Design Problem (collectively, "Consent Alterations"), without first procuring
the prior written consent of Landlord to such Alterations, which consent shall
be requested by Tenant not less than ten (10) business days prior to the
commencement thereof, and which consent shall not be unreasonably withheld by
Landlord and shall state whether the consent alterations must be removed on
termination of the Lease; provided if the Design Problem materially or adversely
affects the Building System or Building Structure, then Landlord may condition
its consent upon Tenant assuring that the proposed Alteration complies with
applicable Laws and complies with other conditions that Landlord may reasonably
require of Tenant. In the event Tenant proposes to make a Consent Alteration,
Tenant's notice regarding the proposed Alteration shall include the plans and
specifications for the Alterations. Landlord shall grant or withhold its consent
to any Consent Alterations within ten (10) business days of receipt of Tenant's
notice; Landlord's failure to respond within three (3) business days after
receipt by Landlord of a second notice given after such ten (10) business day
period shall be deemed to evidence Landlord's approval with respect to the same.
The construction of the initial improvements to the Premises shall be governed
by the terms of the Work Letter and not the terms of this Article 8.

    8.2  Manner of Construction.  In connection with the making of Alterations,
         ----------------------                                                
except for minor or purely cosmetic Alterations such as painting or replacement
of wall covering ("Finish Work"), Tenant shall utilize only contractors and
subcontractors who normally and regularly perform similar work in Comparable
Buildings, or which have been otherwise approved by Landlord, which approval
shall not be unreasonably withheld or delayed.  Subject to the terms of Article
24, below, Tenant shall construct all Alterations in conformance with any and
all applicable rules and regulations of any federal, state, county or municipal
code or ordinance and, when required pursuant to applicable Law, pursuant to a
valid building permit issued by the City of Lake Forest.  Landlord's approval of
the plans, specifications and working drawings for Tenant's Alterations shall
create no responsibility or liability on the part of Landlord for their
completeness, design sufficiency, or compliance with all laws, rules and
regulations of governmental agencies or authorities.  All work with respect to
any Alterations must be done in a good and workmanlike manner and diligently
prosecuted to completion.  Upon completion of any Alterations, Tenant agrees to
cause a Notice of Completion to be recorded in the office of the Recorder of
Orange County in accordance with Section 3093 of the Civil Code of the State of
California or any successor statute, and, except as to Finish Work, Tenant shall
deliver to Landlord a reproducible copy of the construction set of drawings of
the Alterations (or, at Tenant's election, a copy of the final working drawings
for such Alterations, with field changes shown thereon) within thirty (30) days
following completion thereof.

    8.3  Construction Insurance.  Prior to the commencement of any Alteration,
         ----------------------                                               
Tenant shall provide Landlord with reasonable evidence that Tenant carries
"Builder's All Risk" insurance in a commercially reasonable amount given the
scope of such Alterations, covering the construction of such Alterations, it
being understood and agreed that all of such Alterations shall be insured by
Tenant pursuant to Article 10 of this Lease immediately upon completion thereof.
In addition, Landlord may, in its discretion, require any "Transferee," as that
term is defined in Section 14.1, below, other than any Affiliate, to obtain a
lien and completion bond or some alternate form of 

                                       17
<PAGE>
 
security satisfactory to Landlord in an amount sufficient to ensure the lien-
free completion of such Alterations and naming Landlord as a co-obligee.

    8.4  Landlord's Property.  Subject to the terms of this Lease, all
         -------------------                                          
Alterations, improvements, fixtures and/or equipment which may be installed or
placed in or about the Premises, from time to time, shall be at the sole cost of
Tenant and shall be and become the property of Landlord, except that Tenant
shall have the right to remove any such Alterations, not attached or built into
the Premises and trade fixtures which Tenant can reasonably substantiate to
Landlord have not been paid for with any tenant improvement allowance funds
provided to Tenant by Landlord, together with any non-affixed personal property
in the Premises, provided Tenant repairs any damage to the Premises and Building
caused by such removal.  Upon the expiration or early termination of the Lease
Term, Landlord may, by written notice to Tenant, require Tenant at Tenant's
expense to remove any improvements in the Premises, excluding the initial Tenant
Improvements but including any Alterations with respect to which Landlord
designated, in its approval of the Alterations, that the same are to be removed
at the end of the Term of the Lease, and repair any damage to the Premises and
Building caused by such removal, and leave the Premises in a broom-clean
condition.  If Tenant fails to complete such removal and/or to repair any damage
caused by the removal of any such improvement, after notice to Tenant from
Landlord, and a reasonable opportunity (based on the then current circumstances)
for Tenant to complete such removal and/or repair, Landlord may do so and may
charge the cost thereof to Tenant.

                            COVENANT AGAINST LIENS
                            ----------------------

    Tenant has no authority or power to cause or permit any lien or encumbrance
of any kind whatsoever, whether created by act of Tenant, operation of law or
otherwise, to attach to or be placed upon the Real Property, Building or
Premises, and any and all liens and encumbrances created by Tenant shall attach
to Tenant's interest only.  Landlord shall have the right at all times to post
and keep posted on the Premises customary notices of non-responsibility which it
deems necessary for protection from such liens.  Tenant covenants and agrees not
to suffer or permit any lien of mechanics or materialmen or others to be placed
against the Real Property, the Building or the Premises with respect to work or
services claimed to have been performed for or materials claimed to have been
furnished to Tenant or the Premises, and, in case of any such lien attaching or
notice of any such lien, Tenant covenants and agrees to cause it to be
immediately released and removed of record by bond or otherwise within ten (10)
business days after notice by Landlord, and if Tenant shall fail to do so
Landlord, at its sole option, may, after an additional five (5) business days
notice to Tenant, take all action necessary to release and remove such lien,
without any duty to investigate the validity thereof, and all sums, costs and
expenses, including reasonable attorneys' fees and costs, incurred by Landlord
in connection with such lien shall be deemed Additional Rent under this Lease
and shall be due and payable by Tenant within thirty (30) days of receipt of an
invoice therefor.

    10.1 Indemnification and Waiver.
         -------------------------- 

         10.1.1  Waiver.  Tenant hereby assumes all risk of damage to property
                 ------                                                       
or injury to persons in or upon the Premises from any cause whatsoever and
agrees that Landlord, its partners and their respective officers, agents,
servants, and employees (collectively, the "Landlord Parties") shall not be
liable for any damage either to person or property or resulting from the loss of
use thereof, which damage is sustained by Tenant or by other persons claiming
through Tenant, except to the extent caused by the negligence or wilful
misconduct of the Landlord Parties, subject to the provisions of Section 10.4
hereof.

         10.1.2  Tenant's Indemnity.  Tenant shall indemnify, defend, protect,
                 ------------------                                           
and hold harmless Landlord and the Landlord Parties from any and all claims,
loss, cost, damage, expense and liability (including without limitation court
costs and reasonable attorneys' fees) (collectively, "Claims") incurred in
connection with or arising from (1) any cause in or on the Premises during the
Lease Term or any holdover period and (2) subject to the terms of the last
sentence of Section 10.1.3, below, any acts or omissions or wilful misconduct of
Tenant or any person claiming by, through or under Tenant, its partners, and
their respective officers  agents, servants or employees of Tenant or any such
person (collectively, "Tenant Parties"), in or on or about the Premises or the
Real Property either prior to, during, or after the expiration of the Lease
Term, provided that, except as set forth below, the terms of the foregoing
indemnity shall not apply to the extent such Claims arise from the negligence or
wilful misconduct of the Landlord Parties in connection with the Landlord
Parties' activities in, on or about the Real Property, including the Premises,
subject to the provisions of Section 10.4 hereof.  Notwithstanding the
foregoing, because Tenant must carry insurance pursuant to Section 10.3.2,
below, to cover its personal property and all office furniture, trade fixtures,
office equipment and merchandise within the Premises and the Tenant Improvements
and Alterations, Tenant hereby agrees to protect, defend, indemnify and hold
Landlord harmless from any Claim with respect to any such property within the
Premises, to the extent such Claim is covered by Tenant's insurance, even if
resulting from the negligence or wilful misconduct of the Landlord Parties.

         10.1.3  Landlord's Indemnity.  Landlord shall indemnify, defend,
                 --------------------                                    
protect, and hold harmless Tenant and the Tenant Parties from any Claims
incurred in connection with or arising from (1) any cause in or about the Real
Property during the Lease Term (to the extent covered by Landlord's commercial
general liability insurance policies carried pursuant to the terms of Section
10.2 below), or (2) any negligent acts or omissions or wilful misconduct of any
of the Landlord Parties in, on, or about the Premises or the Real Property
(subject to the terms of the last sentence of Section 10.1.2, above), either
prior to, during, or after the expiration of the Lease Term, provided that,
except as set forth below, the terms of the foregoing indemnity shall not apply
to the extent such Claims arise from the negligence or wilful misconduct of the
Tenant Parties in connection with the Tenant Parties' activities in, on, or
about the Real Property.  Notwithstanding the foregoing, because Landlord is
required to maintain pursuant to the terms of Section 10.2, below, insurance on
the Building and Real Property and Tenant compensates Landlord for such
insurance as part of Operating Expenses, Landlord hereby agrees to protect,
defend, indemnify and hold Tenant harmless 

                                       19

from any Claims with respect to the Building and Landlord's equipment and
property on the Real Property to the extent such Claim is covered by Landlord's
insurance, even if resulting from the negligent acts or wilful misconduct of the
Tenant Parties.

          10.1.4  Waiver of Consequential Damages.  Notwithstanding any contrary
                  -------------------------------                               
provision of this Lease, neither Landlord nor Tenant shall be liable to the
other party for any consequential damages for a breach or default under this
Lease, provided that this sentence shall not be applicable to any consequential
damages which may be incurred by the Landlord Parties relating to or in
connection with (i) action taken by or on behalf of Tenant pursuant to the
provisions of Section 7.3, above, or (ii) any holdover by Tenant following the
expiration of the Lease Term, subject to and in accordance with the provisions
of Article 16 hereof.

          10.1.5  General Terms.  The provisions of this Section 10.1 shall
                  -------------                                            
survive the expiration or sooner termination of this Lease with respect to any
claims or liability occurring prior to such expiration or termination.

    10.2  Landlord's Insurance.  Subject to Tenant's right to carry and pay
          --------------------                                             
directly for insurance as permitted by Section 4.1, Landlord shall maintain
during the Lease Term "all-risk" insurance insuring the Building against loss or
damage due to fire and other casualties covered within the classification of
fire and extended coverage, vandalism coverage and malicious mischief, sprinkler
leakage, water damage, and special extended coverage.  Such coverage shall be
written for one hundred percent (100%) of the replacement cost value of the
Building, without deduction for depreciation, and shall be from such companies,
and on such other terms and conditions as Landlord may from time to time
reasonably determine.  Such insurance coverage shall also include a rental loss
endorsement and one or more loss payee endorsements in favor of the holders of
any mortgages or deeds of trust encumbering the interest of Landlord in the Real
Property or the ground or underlying lessors of the Real Property, or any
portion thereof.  Such policy shall also contain a "stipulated value"
endorsement deleting any co-insurance provisions.  Notwithstanding the foregoing
provisions of this Section 10.2, the coverage and amounts of insurance carried
by Landlord in connection with the Building shall at a minimum be comparable to
the coverage and amounts of insurance which are carried by institutional
landlords of Comparable Buildings.  Landlord shall also carry Worker's
Compensation and Employee's Liability coverage as required by applicable law.
Upon inquiry by Tenant, from time to time, Landlord shall inform Tenant of all
such insurance carried by Landlord.  Tenant shall, at Tenant's expense, comply
as to the Premises with all customary insurance company requirements pertaining
to the use of the Premises to the extent consistent with the insurance company
requirements imposed at the Comparable Buildings.  If Tenant's conduct or use of
the Premises other than for the uses permitted under Section 5.1 of this Lease
causes any increase in the premium for such insurance policies, then Tenant
shall, following notice from Landlord either (i) cease such conduct or use, or
(ii) reimburse Landlord for any such increase. Tenant, at Tenant's expense,
shall comply with all rules, orders, regulations or requirements of the American
Insurance Association (formerly the National Board of Fire Underwriters) and
with any similar body to the extent consistent with the rules, orders,
regulations or requirements imposed at the Comparable Buildings.  Landlord may
carry earthquake and flood insurance with a deductible of not less than five
percent (5%) of the replacement value of the Building at the time of loss and
not more than the amount of deductible then customarily maintained under similar
insurance with respect to Comparable Projects, and Tenant will reimburse
Landlord for the premium cost thereof up to Sixty Thousand and 

                                       20

00/100 Dollars ($60,000.00) per year, plus annual increases thereof in an amount
no greater on a percentage basis than the annual percentage increase in the
Consumer Price Index for All Urban Consumers (base year 1982-1984'100) for the
Los Angeles, Anaheim, Riverside area published by the United States Department
of Labor, Bureau of Labor Statistics.

    10.3  Tenant's Insurance.  Tenant shall maintain the following coverages in
          ------------------                                                   
the following amounts.

          10.3.1  Commercial General Liability Insurance covering the insured
against claims of bodily injury, personal injury and property damage arising out
of Tenant's operations or use of the Premises, including a Broad Form Commercial
General Liability endorsement covering the insuring provisions of this Lease and
covering the performance by Tenant of the indemnity agreements set forth in
Section 10.1 of this Lease, for limits of liability not less than:

          Bodily Injury and
          Property Damage Liability        $5,000,000 each occurrence
                                           $5,000,000 annual aggregate
                                       
          Personal Injury Liability        $5,000,000 each occurrence
                                           $5,000,000 annual aggregate

          10.3.2  "All-Risk" Insurance, with commercially reasonable
deductibles, covering (i) all office furniture, trade fixtures, office
equipment, merchandise and all other items of Tenant's property on the Premises
installed by, for, or at the expense of Tenant, (ii) the Tenant Improvements,
and (iii) all other improvements, alterations and additions to the Premises,
including any improvements, alterations or additions installed at Tenant's
request above the ceiling of the Premises or below the floor of the Premises.
Such insurance shall be written for the full replacement cost value, new,
without deduction for depreciation, of the covered items and in amounts that
meet any co-insurance clauses of the policies of insurance and may include, at
Tenant's sole option, a vandalism and malicious mischief endorsement, and
sprinkler leakage coverage.

          10.3.3  Form of Policies.  The minimum limits of policies of liability
                  ----------------                                              
insurance required of Tenant or Landlord under this Lease shall in no event
limit the liability of Tenant or Landlord under this Lease.  Each party's
insurance shall (i) name the other party (including, as to Landlord, the
"Lender," as described in Article 18 below), as an additional insured; (ii)
specifically cover the Tenant's indemnity obligations of the insuring party set
forth in Section 10.1 of this Lease to the extent customarily and commercially
available; (iii) be issued by an insurance company having a rating of not less
than B+/VII in Best's Insurance Guide or which is otherwise reasonably
acceptable to the named party and licensed to do business in the State of
California; (iv) be primary insurance as to all claims thereunder and provide
that any insurance carried by the named party is not excess and is non-
contributing with any insurance requirement of the insuring party; and (v)
contain a cross-liability endorsement or severability of interest clause
acceptable to the named party.  The insuring party shall cause its insurance
carrier to provide that said insurance carrier shall give thirty (30) days'
prior written notice to the named party and any mortgagee or ground or
underlying lessor of the named party prior to the date said insurance is
canceled.  The parties agree that the insuring party may satisfy its insurance
requirements herein with a "blanket" or "umbrella" insurance policy covering the

                                       21
<PAGE>
 
Premises and other premises of the insuring party.  The insuring party shall
deliver said policy or policies or certificates thereof to the named party on or
before the date that Tenant first enters the Premises for purposes of performing
any work or installing any of its fixtures, equipment or personal property and
at least thirty (30) days before the expiration dates thereof.  In the event the
insuring party shall fail to procure such insurance, or to deliver such policies
or certificate at least thirty (30) days before the expiration dates thereof,
the named party may, at its option, if such failure continues for ten (10)
business days following written notice to the insuring party, procure such
policies for the account of the insuring party, and the cost thereof shall be
paid to the named party as Additional Rent within thirty (30) days after
delivery to the insuring party of bills therefor.

     10.4 Subrogation.  Landlord and Tenant agree to have their respective
          -----------                                                     
insurance companies issuing property damage insurance waive any rights of
subrogation that such companies may have against Landlord or Tenant, as the case
may be.  Landlord and Tenant hereby waive any right that either may have against
the other on account of any loss or damage to their respective property to the
extent such loss or damage is insurable under the types of policies of insurance
set forth in Sections 10.2 and 10.3.2, above.

     10.5 Additional Insurance Obligations.  Tenant shall carry and maintain
          --------------------------------                                  
during the entire Lease Term, at Tenant's sole cost and expense, such increased
amounts of the insurance required to be carried by Tenant pursuant to this
Article 10, and such other reasonable types of insurance coverage (exclusive, as
to insurance required under the provisions of Section 10.3, of earthquake and
flood insurance) and in such reasonable amounts covering the Premises and
Tenant's operations therein, as may be reasonably requested by Landlord;
provided that such requests shall be consistent with the treatment of comparable
tenants in the Comparable Buildings.

                            ----------------------

     11.1 Repair of Damage to Premises by Landlord.  Except in the case where
          ----------------------------------------                           
Landlord or its agents are already aware of the same, Tenant shall notify
Landlord of any material damage to the Premises resulting from fire or any other
casualty promptly following the date Tenant becomes aware of such damage.  If
the Building or Premises shall be damaged by fire or other casualty, Landlord
shall promptly and diligently, subject to reasonable delays for insurance
adjustment or other matters beyond Landlord's reasonable control, and subject to
all other terms of this Article 11, restore the Building, the Building Structure
and Building Systems, except for those items which were constructed by or for
the benefit of Tenant above and beyond the Tenant Improvement Allowance (the
"Base, Shell and Core") .  Such restoration shall be to substantially the same
condition of the Base, Shell and Core prior to the casualty, except for
modifications required by zoning and building codes and other laws.
Notwithstanding any other provision of this Lease, upon the occurrence of any
damage to the Premises, Tenant shall assign to Landlord (or to any party
designated by Landlord) all insurance proceeds payable to Tenant under Tenant's
insurance required under items (ii) and (iii) of Section 10.3.2 of this Lease,
and Landlord shall repair any injury or damage to the Tenant Improvements
installed in the Premises and shall return such Tenant Improvements to their
original condition.  Except as provided below with respect to the termination of
the Lease, if the cost of restoration of the Base, Shell and Core shall exceed
the amount of insurance proceeds scheduled to 

                                       22
<PAGE>
 
be received by Landlord from Landlord's casualty, earthquake and/or flood
insurance due to the deductible amounts under such insurance (which deductible
amounts shall not be in excess of commercially reasonable amounts for Comparable
Buildings), Tenant shall pay such shortfall (not to exceed the deductible
amounts permitted under this Lease) to Landlord prior to Landlord's repair of
the damage to the Base, Shell and Core. If the cost of such repair to the Tenant
Improvements by Landlord is estimated, after review of the costs by Tenant, to
exceed the amount of insurance proceeds scheduled to be received by Landlord
from Tenant's insurance carrier, as assigned by Tenant, Tenant shall pay any
such short fall to Landlord prior to Landlord's repair of the damage. In the
event this Lease shall terminate as a result of such damage, (i) Tenant shall
pay the amount of the deductible under Landlord's policy only if the termination
is a result of Tenant's election to terminate under Section 11.2.2 below, (ii)
Tenant shall assign to Landlord the right to receive any insurance proceeds
received from Tenant's insurance carrier related to the Tenant Improvements
constructed utilizing the proceeds of the Tenant Improvement Allowance, and
(iii) Tenant shall retain the insurance proceeds related to those of the Tenant
Improvements which were constructed utilizing funds provided by Tenant over and
above the Tenant Improvement Allowance. Tenant shall retain all insurance
proceeds related to Tenant's personal property, furniture, fixtures and
equipment. In connection with such repairs and replacements, Tenant shall, prior
to the commencement of construction of the Tenant Improvements, submit to
Landlord, for Landlord's review and approval, which approval shall not be
unreasonably withheld, conditioned, or delayed, all plans, specifications and
working drawings relating thereto, and Tenant shall have the right to alter the
design of the previously existing Tenant Improvements, provided that such
redesign shall not delay the repairs and restoration, and Landlord shall select
the contractors to perform such improvement work; provided, however, that Tenant
shall have the right to approve the contractor and the primary subcontractors
relating to the Tenant Improvements, which approval shall not be unreasonably
withheld, conditioned or delayed. Landlord shall not be liable for any
inconvenience or annoyance to Tenant or its visitors, or injury to Tenant's
business resulting in any way from such damage or the repair thereof; provided
however, that as a result of such damage Tenant may be entitled to abatement of
Rent pursuant to the terms of Section 6.4 of this Lease.

     11.2  Landlord's Option to Repair.
           --------------------------- 

           11.2.1  Landlord Right To Terminate.  Notwithstanding the terms of
                   ---------------------------                               
Section 11.1 of this Lease, Landlord may elect not to rebuild and/or restore the
Premises and/or Building and/or Real Property and instead terminate this Lease
by notifying Tenant in writing (the "Landlord Termination Notice") of such
termination within sixty (60) days after the date of Landlord's discovery of
damage (the "Damage Date"), such notice to include a termination date giving
Tenant ninety (90) days to vacate the Premises, but Landlord may so elect only
if the Premises, Building and/or Real Property shall be damaged by fire or other
casualty or cause, whether or not the Premises are affected, and one or more of
the following conditions is present:  (i) repairs cannot reasonably be completed
within two hundred forty (240) days of the Damage Date (when such repairs are
made without the payment of overtime or other premiums); (ii) over One Million
Five Hundred Thousand Dollars ($1,500,000.00) of the cost of the damage is not
covered, excluding deductible amounts, by Landlord's insurance policies (which
One Million Five Hundred Thousand Dollar ($1,500,000.00) amount shall decline,
on a straight line basis, over the seven (7) years of the term of this Lease,
each year reducing such amount by Two Hundred Fourteen Thousand Dollars
($214,000.00)),or (iii) the holder of any mortgage on the Building or Real
Property shall require (based on such holder's legal right to so 

                                       23
<PAGE>
 
require) that the insurance proceeds or any portion thereof be used to retire
the mortgage debt and the remaining proceeds are more than Three Hundred 
Seventy-Five Thousand and 00/100 Dollars ($375,000) less than the amount
required to repair the damage.

          11.2.2  Tenant's Right to Terminate.  If Landlord does not elect to
                  ---------------------------                                
terminate this Lease pursuant to Landlord's termination right as provided above,
and the repairs of such damage cannot, in the reasonable judgment of the
contractor selected by Landlord to complete such repairs, be completed to the
standard set forth in Section 11.1, above, within two hundred forty (240) days
after the Damage Date (which two hundred forty (240) day period shall not be
subject to extension as a result of any "Force Majeure" as that term is defined
in Article 21, below), Landlord shall, within sixty (60) days after the Damage
Date, deliver notice of such fact to Tenant.  Within thirty (30) days after
Tenant's receipt of such notice, Tenant may elect to terminate this Lease by
written notice to Landlord effective as of the date specified in Tenant's
notice, which date may be up to ninety (90) days following the date of the
notice.  Furthermore, if neither Landlord nor Tenant has terminated this Lease,
and the repairs are not actually completed within such two hundred forty (240)
day period, as such period is extended by Force Majeure delays and Tenant
Delays, Tenant shall have the right to terminate this Lease within five (5)
business days of the end of such period and thereafter during the first five (5)
business days of each calendar month following the end of such period until such
time as the repairs are complete, by notice to Landlord (the "Damage Termination
Notice"), effective as of a date set forth in the Damage Termination Notice (the
"Damage Termination Date"), which Damage Termination Date shall not be less than
five (5) business days following the end of such period or each such month, as
the case may be.  Notwithstanding the foregoing, if Tenant delivers a Damage
Termination Notice to Landlord, then Landlord shall have the right, which may
only be exercised once with respect to any specific event of damage or
destruction, to suspend the occurrence of the Damage Termination Date for a
period ending thirty (30) days after the Damage Termination Date set forth in
the Damage Termination Notice by delivering to Tenant, within five (5) business
days of Landlord's receipt of the Damage Termination Notice, a certificate of
Landlord's contractor responsible for the repair of the damage certifying that
it is such contractor's good faith judgment that the repairs shall be
substantially completed within thirty (30) days after the Damage Termination
Date.  If repairs shall be substantially completed prior to the expiration of
such thirty-day period, then the Damage Termination Notice shall be of no force
or effect, but if the repairs shall not be substantially completed within such
thirty-day period, then this Lease shall terminate upon the expiration of such
thirty-day period.  At any time, from time to time, after the date occurring
thirty (30) days after the Damage Date, Tenant may request that Landlord provide
Tenant with a certificate from the or contractor described above setting forth
such  contractor's reasonable opinion of the date of completion of the repairs
and Landlord shall respond to such  request within five (5) business days.

          11.2.3  Damage Near End of Term.  Despite any other provision of this
                  -----------------------                                      
Article 11, if the Premises or Building is destroyed or damaged by a casualty in
the period of the Lease Term set forth below (and Tenant has not previously or
within sixty (60) days after the Damage Date irrevocably exercised an available
option to extend the Lease Term pursuant to Section 2.2 of this Lease), then the
two hundred forty (240) day period specified in Section 11.2.1 and Section
11.2.2 and the amount of deductible under Landlord's policy which Tenant is
otherwise required to pay under Section 11.1(i) shall be reduced to the number
of days and the amounts indicated as the Time to Completion and the amount of
Deductible payable by Tenant.

     11.3 Waiver of Statutory Provisions.  The provisions of this Lease,
          ------------------------------                                
including this Article 11, constitute an express agreement between Landlord and
Tenant with respect to any and all damage to, or destruction of, all or any part
of the Premises, the Building or the Real Property, and any statute or
regulation of the State of California, including, without limitation, Sections
1932(2) and 1933(4) of the California Civil Code, with respect to any rights or
obligations concerning damage or destruction in the absence of an express
agreement between the parties, and any other statute or regulation, now or
hereafter in effect, shall have no application to this Lease or any damage or
destruction to all or any part of the Premises, the Building or the Real
Property.

                                   ---------

     No waiver of any provision of this Lease shall be implied by any failure of
either party to enforce any remedy on account of the violation of such
provision, even if such violation shall continue or be repeated subsequently,
any waiver by either party of any provision of this Lease may only be in
writing, and no express waiver shall affect any provision other than the one
specified in such waiver and that one only for the time and in the manner
specifically stated.  No receipt of monies by Landlord from Tenant after the
termination of this Lease shall in any way alter the length of the Lease Term.

     13.1 Permanent Taking.  If the whole or any part of the Premises or
          ----------------                                              
Building shall be taken by power of eminent domain or condemned by any competent
authority for any public or quasi-public use or purpose, or if any adjacent
property or street shall be so taken or condemned, or reconfigured or vacated by
such authority in such manner as to require the use, reconstruction or
remodeling of any part of the Premises or Building, or if Landlord shall grant a
deed or other instrument in lieu of such taking by eminent domain or
condemnation (collectively, a "Taking"), and if such Taking involves a Taking of
all or substantially all of the Premises, Landlord shall have the option to
terminate this Lease upon delivery of ninety (90) days' notice, provided such
notice is given no later than one hundred eighty (180) days after the date of
such taking, condemnation, reconfiguration, vacation, deed or other instrument.
If more than twenty-five percent (25%) of the rentable square feet of the
Premises is taken, or if less than twenty five percent (25%) of the rentable
square feet of the Premises is taken and Tenant is unable to reasonably conduct
its business within the Premises, or if parking is substantially interfered
with, or if access to the Premises is substantially interfered with,

Tenant shall have the option to terminate this Lease upon delivery of ninety
(90) days' notice, provided such notice is given no later than one hundred
eighty (180) days after the date of such taking. Landlord shall be entitled to
receive the entire award or payment in connection therewith, except that Tenant
shall have the right to receive an award for fifty percent (50%) of the "bonus
value" of its leasehold interest hereunder (which bonus value shall be equal to
the sum paid by the condemning authority as the award for compensation for
taking the leasehold created by this Lease), its relocation expenses, damages to
Tenant's personal property, trade fixtures, and loss of goodwill. All Rent shall
be apportioned as of the date of such termination, or the date of such taking,
whichever shall first occur. If any part of the Premises shall be taken, and
this Lease shall not be so terminated, the Rent shall be proportionately abated
or reduced based on the number of rentable square feet of the Premises so taken.
Tenant hereby waives any and all rights it might otherwise have pursuant to
Section 1265.130 of The California Code of Civil Procedure, or any successor
statute.

     13.2 Temporary Taking.  Notwithstanding anything to the contrary contained
          ----------------                                                     
in this Article 13, in the event of a temporary taking of all or any portion of
the Premises for a period of one hundred and twenty (120) days or less, then
this Lease shall not terminate but the Base Rent and the Additional Rent shall
be abated for the period of such taking (commencing on the date of such taking)
in proportion to the ratio that the amount of rentable square feet of the
Premises taken bears to the total rentable square feet of the Premises; provided
that if the remaining portion of the Premises is not sufficient to allow Tenant
to effectively conduct its business therein, and if Tenant does not conduct its
business from such remaining portion, then Base Rent and the Additional Rent
shall be abated for the entire Premises for such time as Tenant continues to be
so prevented from using, and does not use, the Premises.  Landlord shall be
entitled to receive the entire award made in connection with any such temporary
taking.

                           ASSIGNMENT AND SUBLETTING
                           -------------------------

     14.1 Transfers.  Subject to the provisions of this Article 14, Tenant shall
          ---------                                                             
not, without the prior written consent of Landlord, assign, mortgage, pledge,
hypothecate, encumber, or permit any lien to attach to, or otherwise transfer,
this Lease or any interest hereunder, permit any assignment or other transfer of
this Lease or any interest hereunder by operation of law, sublet the Premises or
any part thereof, or otherwise permit the occupancy or use of the Premises by
any persons other than Tenant, its Affiliates and their employees (all of the
foregoing are hereinafter sometimes referred to collectively as "Transfers" and
any person to whom any Transfer is made or sought to be made is hereinafter
sometimes referred to as a "Transferee").  Any Transfer with respect to which
Landlord's consent is required under this Article 14 and with respect to which
such consent requirement is not exempted under this Article 14 is referred to
herein as a "Consent Transfer."  If Tenant desires Landlord's consent to any
Consent Transfer, Tenant shall notify Landlord in writing, which notice (the
"Transfer Notice") shall include (i) the proposed effective date of the
Transfer, which shall not be less than (a) in the case of a sublease of less
than 24,000 rentable square feet, ten (10) business days, (b) in the case of a
sublease of 24,000 square feet or more, fifteen (15) business days, and (c) in
the case of an assignment of this Lease or any other Transfer, twenty (20)
business days after the date of delivery of the Transfer Notice, (ii) a
description of the portion of the Premises to be transferred (the "Subject
Space"), (iii) all of the principal terms of the proposed Transfer and the
consideration 

                                       26

therefor, including a calculation of the "Transfer Premium," as that term is
defined in Section 14.3 below, in connection with such Transfer, the name and
address of the proposed Transferee, and a copy of all existing and/or proposed
documentation pertaining to the proposed Transfer, including all then existing
material, executed operative documents to evidence such Transfer or the
agreements incidental or related to such Transfer, (iv) current financial
statements of the proposed Transferee and (v) to the extent reasonably
available, any other reasonable information reasonably and customarily required
by landlords of Comparable Buildings in connection with the review of similar
Transfers. Subject to the terms of this Article 14, any Consent Transfer made
without Landlord's prior written consent shall, at Landlord's option, be null,
void and of no effect. Whether or not Landlord consents to any Consent Transfer,
Tenant shall pay Landlord's review and processing fees, as well as any
reasonable legal fees incurred by Landlord, within thirty (30) days after
written request by Landlord, all of which costs shall not exceed, as to any
specific request for Landlord approval, the sum of $2,500.

     14.2 Landlord's Consent.  Landlord shall not unreasonably withhold, delay

or condition its consent to any proposed Consent Transfer.  Subject to the
provisions of this Section 14.2, the parties hereby agree that it shall be
reasonable under this Lease and under any applicable law for Landlord to
withhold consent to any proposed Consent Transfer where one or more of the
following apply, without limitation as to other reasonable grounds for
withholding consent:

          14.2.1  The Transferee is of a character or reputation or engaged in a
business which is materially inconsistent with the quality of the Building; or

          14.2.2  The Transferee intends to use the Subject Space for purposes
which are inconsistent with those permitted under this Lease; or

          14.2.3  The Transferee is not a party of reasonable financial worth
and/or financial stability in light of the responsibilities to be undertaken in
connection with the Transfer on the date consent is requested; provided that the
provisions of this Section 14.2. shall be applicable only if (i) the proposed
                   -------------                                             
Transfer is an assignment of Tenant's interest in the Lease, (ii) the proposed
Transfer concerns twenty thousand (20,000) rentable square feet or more of the
Premises, or (iii) upon the consummation of the proposal Transfer, the Original
Tenant and/or its Affiliates will not continue to directly occupy (i.e., have
not subleased or otherwise transferred its space) at least forty thousand
(40,000) rentable square feet of the Premises.

     If Landlord consents to any Consent Transfer pursuant to the terms of this
Section 14.2, Tenant may within nine (9) months after Landlord's consent, but
not later than the expiration of said nine-month period, enter into such
Transfer of the Premises or portion thereof, provided that if there are any
material changes in the terms and conditions from those specified in the
Transfer Notice such that Landlord would initially have been entitled to refuse
its consent to such Transfer under this Section 14.2, Tenant shall again submit
the Transfer to Landlord for its consent under this Article 14.

     14.3 Transfer Premium.
          ---------------- 

          14.3.1  Definition of Transfer Premium.  Subject to the terms of this
                  ------------------------------                               
Article 14, if Landlord consents to a Consent Transfer, as a condition thereto
which the parties hereby agree is 

                                       27
<PAGE>
 
reasonable, Tenant shall pay to Landlord fifty percent (50%) of any "Transfer
Premium," as that term is defined in this Section 14.3, received by Tenant from
such Transferee. "Transfer Premium" shall mean all rent, additional rent or
other consideration payable by such Transferee in connection with the Transfer
in excess of the Rent and Additional Rent payable by Tenant under this Lease
during the term of the Transfer on a per rentable square foot basis if less than
all of the Premises is transferred (unless all or a portion of the Subject Space
is subject to different Rent and Additional Rent terms, in which case, to the
extent applicable, such different terms shall be applicable), after deducting
the actual, out-of-pocket expenses incurred or to be incurred by Tenant for the
following (collectively, the "Subleasing Costs") (i) any changes, alterations
and improvements to the Premises in connection with the Transfer, (ii) any space
planning, architectural or design fees or expenses incurred in marketing such
space or in connection with such Transfer, (iii) any improvement allowance or
other monetary concessions provided to the Transferee, (iv) any brokerage
commissions incurred by Tenant in connection with the Transfer, (v) legal fees
incurred in connection with the Transfer, including those fees and costs
reimbursed to Landlord pursuant to the last sentence of Section 14.1, (vi) any
lease takeover costs incurred by Tenant in connection with the Transfer, (vii)
out-of-pocket costs of advertising the space which is the subject of the
Transfer, and (viii) the amount of any Base Rent and Additional Rent paid by
Tenant to Landlord with respect to the Subject Space during the period, not to
exceed four (4) months, commencing on the later of (a) the earlier of the date
Tenant contracts with a reputable broker to market the Subject Space or
commences negotiations with the Transferee as evidenced by an exchange of
proposals, or (b) the date Tenant vacates the Subject Space, until the
commencement of the term of the Transfer. "Transfer Premium" shall also include,
but not be limited to, key money, bonus money or other cash consideration paid
by Transferee to Tenant in connection with such Transfer, but shall exclude any
payment which is not in excess of fair market value for (i) services rendered by
Tenant to Transferee or (ii) for assets, fixtures, inventory, equipment, or
furniture transferred by Tenant to Transferee in connection with such Transfer.

          14.3.2  Payment of Transfer Premiums.  The determination of the amount
                  ----------------------------                                  
of the Transfer Premium shall be made on a monthly basis in accordance with the
terms of this Section 14.3.2, as rent or other consideration is received by
Tenant by under the Transfer.  For purposes of calculating the Transfer Premium,
Tenant's Subleasing Costs shall be credited against the first amounts received
by Tenant as a result of the Transfer.

     14.4 Effect of Transfer.  Subject to the terms of this Article 14, if
          ------------------                                              
Landlord consents to a Consent Transfer, (i) the terms and conditions of this
Lease shall in no way be deemed to have been waived or modified, (ii) such
consent shall not be deemed consent to any further Consent Transfer by either
Tenant or a Transferee, (iii) Tenant shall deliver to Landlord, promptly after
execution, an original executed copy of all documentation pertaining to the
Transfer, and (iv) Tenant shall furnish upon Landlord's request a reasonable
statement, certified by an independent certified public accountant, or Tenant's
chief financial officer or other appropriate officer of Tenant, setting forth in
reasonable detail the computation of any Transfer Premium Tenant has derived and
expects to derive from such Transfer.  Except as set forth in Section 14.4
above, no Transfer relating to this Lease or agreement entered into with respect
thereto, whether with or without Landlord's consent, shall relieve Tenant from
liability under this Lease, including, without limitation, in connection with
the Subject Space; provided, however, Tenant and the Guarantor shall be relieved
and released from all liability under this Lease if the Transferee and/or any
guarantor of the Transferee's obligations under this Lease (pursuant to a
written guaranty in the form attached hereto as Exhibit L) has a long term debt

credit rating from Standard & Poors of BBB- or better and a combined net worth
of $250,000,000 or more; provided further, however, that such Transferee's
obligations shall be guaranteed under a guaranty in the same form as the
Guaranty attached to this Lease as Exhibit L if Transferee is a wholly-owned

subsidiary or controlled by a third party entity, or, at Landlord's sole
election, an agreement other than a guaranty may be reached between Landlord and
the entity controlling the Transferee, whereby such entity agrees not to
denigrate the financial condition of such Transferee during the term of the
Lease.  Landlord or its authorized representatives shall have the right at all
reasonable times during normal business hours following ten (10) business days
advance notice to audit the books, records and papers of Tenant directly
relating to any Consent Transfer.  If the Transfer Premium respecting any
Consent Transfer shall be found understated, or overstated, the appropriate
party shall within thirty (30) days after demand, pay to the other the
deficiency or excess, and if understated by more than ten percent (10%), Tenant
shall pay Landlord's costs of such audit.

     14.5 Non-Transfers.  Notwithstanding anything to the contrary contained in
          -------------                                                        
this Article 14, an assignment of this Lease or subletting of all or a portion
of the Premises to an entity (an "Affiliate") which is controlled by, controls,
or is under common control with, Tenant or Tenant's parent or any subsidiary of
Tenant or Tenant's parent, or to a resulting entity from a merger or
consolidation of Tenant with another entity, shall not be deemed a Transfer
under this Article 14, and Landlord's consent shall not be required in
connection therewith, provided that Tenant notifies Landlord of any such
assignment or sublease and promptly supplies Landlord with any documents or
information reasonably requested by Landlord regarding such assignment or
sublease or such Affiliate or resulting entity, and further provided that such
assignment or sublease is not a subterfuge by Tenant to avoid its obligations
under this Lease and shall in no way relieve Tenant from any liability under
this Lease.  "Control," as used in this Section 14.5, shall mean the possession,
direct or indirect, of the power to direct or cause the direction of the
management and policies of a person or entity, whether through the ownership of
voting securities, by contract or otherwise.  As used in this Section 14.5,
"Affiliate" shall also include any entity which is subleasing from Tenant less
than 12,000 square feet of rentable area of the Premises and on a consolidated
basis no more than 36,000 square feet and with respect to which no demising wall
is to be erected, and with the only identification of such subtenant appearing
on the door or doors to the offices, if any, in that portion or portions of the
Premises being occupied by such sublessee.

acceptance by Landlord of a surrender of the Premises unless such intent is
specifically acknowledged in a writing signed by Landlord.  The delivery of keys
to the Premises to Landlord or any agent or employee of Landlord shall not
constitute a surrender of the Premises or effect a termination of this Lease,
whether or not the keys are thereafter retained by Landlord, and notwithstanding
such delivery Tenant shall be entitled to the return of such keys at any
reasonable time upon request until this Lease shall have been properly
terminated.  The voluntary or other surrender of this Lease by Tenant, whether
accepted by Landlord or not, or a mutual termination hereof, shall not work a
merger.

possession of the Premises to Landlord in good order and condition, reasonable
wear and tear, casualty events, damage resulting from the negligence or
misconduct of the Landlord Parties, and repairs which are specifically made the
responsibility of Landlord hereunder excepted.  Upon such expiration or
termination, Tenant shall, without expense to Landlord, remove or cause to be
removed from the Premises all debris and rubbish, and such items of free-
standing furniture, equipment, cabinet work, and other personal property owned
by Tenant or installed or placed by Tenant at its expense in the Premises, and
such similar articles of any other persons claiming under Tenant, as Landlord
may, in its sole discretion, require to be removed, and, subject to the terms of
this Lease, Tenant shall repair at its own expense all damage to the Premises
and Building resulting from such removal.

                                 HOLDING OVER
                                 ------------

          (a)  If Tenant holds over after the expiration of the Lease Term
hereof, with or without the express or implied consent of Landlord, such tenancy
shall be from month-to-month only, and shall not constitute a renewal hereof or
an extension for any further term, and in such case Base Rent shall be payable
at a monthly rate equal to one hundred twenty-five percent (125%) of the Base
Rent applicable during the last rental period of the Lease Term under this
Lease.  Such month-to-month tenancy shall be subject to every other term,
covenant and agreement contained herein.  Nothing contained in this Article 16
shall be construed as consent by Landlord to any holding over by Tenant, and
Landlord expressly reserves the right to require Tenant to surrender possession
of the Premises to Landlord as provided in this Lease upon the expiration or
other termination of this Lease.  Except for the time limitation on Landlord's
right to seek consequential damages set forth in the next sentence (which time
limitation shall also apply to Landlord's rights to seek damages other than by
reason of the following sentence), the provisions of this Article 16 shall not
be deemed to limit or constitute a waiver of any other rights or remedies of
Landlord provided herein or at law.  If Tenant fails to surrender the Premises
within sixty (60) days after the termination or expiration of this Lease, then,
in addition to any other liabilities to Landlord accruing therefrom, Tenant
shall protect, defend, indemnify and hold Landlord harmless from all loss, costs
(including reasonable attorneys' fees) and liability resulting from such
failure, including, without limiting the generality of the foregoing, any claims
made by any succeeding tenant founded upon such failure to surrender, and any
lost profits to Landlord resulting therefrom.

          (b)  Notwithstanding the foregoing, by written notice to Landlord
given at least one hundred twenty (120) days prior to the expiration of the
original Term, Tenant shall have one time right to elect to holdover in the
Premises (which holdover will be deemed to be with Landlord's consent) for one
(1), two (2), or three (3) full months (as specified in Tenant's notice) at the
same Monthly Base Rent and Additional Rent in effect under this Lease
immediately prior to such holdover, and such continued occupancy by Tenant shall
be subject to all of the other terms, covenants and conditions of this Lease, so
far as applicable. The Lease Term will be extended for the period specified in
such notice by Tenant to Landlord and a vacation of the Premises by Tenant 

                                       30
<PAGE>
 
prior to such date will not relieve Tenant of liability for Monthly Base Rent
and Additional Rent accruing under this Lease through the expiration of the
Term, as extended pursuant to Tenant's notice. The provisions of this Subsection
16(b) will survive the expiration or earlier termination of this Lease.

                             ---------------------

     Within fifteen (15) business days following a request in writing by
Landlord, Tenant shall execute and deliver to Landlord an estoppel certificate,
which, as submitted by Landlord, shall be substantially in the form of Exhibit 
                                                                       -------
E, attached hereto, indicating therein any exceptions thereto that may exist at

that time, and shall also contain any other customary factual information
certified to Tenant's knowledge, without a duty of investigation or inquiry by
Tenant, reasonably requested by Landlord or Landlord's mortgagee or prospective
mortgagee.  Tenant shall execute and deliver whatever other instruments may be
reasonably required for such purposes.  Landlord hereby agrees to provide to
Tenant an estoppel certificate signed by Landlord, containing the same types of
information, and within the same periods of time, as set forth above, with such
changes as are reasonably necessary to reflect that the estoppel certificate is
being granted to Tenant by Landlord, rather than being granted by Tenant to
Landlord or to a lender.

                                 SUBORDINATION
                                 -------------

     Subject to the terms of this Article 18, this Lease shall be subject and
subordinate to all future ground or underlying leases of the Real Property and
to the lien of any "Lender," which in this Lease shall mean any mortgagee under
a mortgage or beneficiaries under any trust deeds hereafter in force against the
Real Property and the Building, if any, and to all renewals, extensions,
modifications, consolidations and replacements thereof, and to all advances made
or hereafter to be made upon the security of such mortgages or trust deeds,
unless the Lenders or the lessors under such ground lease or underlying leases,
require in writing that this Lease be superior thereto.  As of the date of
execution and delivery of this Lease, Landlord has not acquired title to the
Real Property; therefore, Landlord will not be in a position to provide a Non-
Disturbance Agreement to Tenant from the entity presently holding a recorded
interest in the Real Property.  However, following Landlord's acquisition of
title to the Real Property, Landlord's delivery to Tenant of commercially
reasonable non-disturbance agreement(s) in favor of Tenant from any ground
lessors or Lenders, or ground lessors or Lenders who come into existence at any
time prior to the expiration of the Lease Term shall be in consideration of, and
a condition precedent to, Tenant's agreement to be bound by the terms of this
Article 18.  Such commercially reasonable non-disturbance agreements shall
- ----------                                                                
include the obligation of any such successor ground lessor or Lender to
recognize Tenant's rights specifically set forth in this Lease to offset against
Rent next due hereunder (i) any improvement allowance granted under the Work
Letter to the extent same has not been paid when due, and (ii) any unpaid
arbitration or court award made prior to the ground lessor or Lender succeeding
to the rights of Landlord under this Lease.  Subject to the non-disturbance
agreements described above, Tenant covenants and agrees in the event any
proceedings are brought for the foreclosure (or deed lieu thereof) of any such

                                       31

mortgage, or if any ground or underlying lease is terminated, to attorn, to the
lien  holder or purchaser or any successors thereto upon any such foreclosure
sale (or deed in lieu thereof), or to the lessor of such ground or underlying
lease, as the case may be, if so requested to do so by such purchaser or lessor,
and to recognize such purchaser or lessor as the lessor under this Lease.
Tenant shall, within fifteen (15) business days of request by Landlord, execute
such further instruments or assurances as Landlord may reasonably deem necessary
to evidence or confirm the subordination or superiority of this Lease to any
such mortgages, trust deeds, ground leases or underlying leases, subject to the
terms of this Article 18.

     Without limiting the foregoing, Landlord will obtain execution of the
Subordination, Non-Disturbance and Attornment Agreement in the form of Exhibit I
                                                                       ---------

     19.1 Events of Default.  The occurrence of any of the following shall
          -----------------                                               
constitute an event of default ("Event of Default") under this Lease by Tenant:

          19.1.1  Any failure by Tenant to pay any Rent or any other charge
required to be paid under this Lease, or any part thereof, within ten (10)
business days after delivery of written notice to Tenant that such sum is past
due; or

          19.1.2  Any failure by Tenant to observe or perform any other
provision, covenant or condition of this Lease to be observed or performed by
Tenant where such failure continues for thirty (30) days after written notice
thereof from Landlord to Tenant; provided that if the nature of such default is
such that the same cannot reasonably be cured within a thirty (30)-day period,
Tenant shall not be deemed to be in default if it commences such cure within
such period and thereafter proceeds to rectify and cure said default with
reasonable diligence; or

          19.1.3  The failure by Tenant to observe or perform according to the
provisions of Article 17 or Article 18 of this Lease where such failure
continues for more than ten (10) business days after notice from Landlord.

          All notices to be given pursuant to this Section 19.1 shall be in
addition to and not in lieu of the notice requirements of the California Code of
Civil Procedure (S) 1161 et seq.

     19.2 Remedies Upon Default.  Upon the occurrence of any Event of Default by

Tenant, Landlord shall have, in addition to any other remedies available to
Landlord at law or in equity, the option to pursue any one or more of the
following remedies, each and all of which shall be cumulative and nonexclusive,
without any notice or demand whatsoever.

          19.2.1  Terminate this Lease, in which event Tenant shall immediately
surrender the Premises to Landlord, and if Tenant fails to do so, Landlord may,
subject to due process of law and without prejudice to any other remedy which it
may have for possession or arrearages in rent, enter 

                                       32
<PAGE>
 
upon and take possession of the Premises and expel or remove Tenant and any
other person who may be occupying the Premises or any part thereof; and Landlord
may recover from Tenant the following:

                  (i)    The worth at the time of award of any unpaid rent which
     has been earned at the time of such termination; plus

                  (ii)   The worth at the time of award of the amount by which
     the unpaid rent which would have been earned after termination until the
     time of award exceeds the amount of such rental loss that Tenant proves
     could have been reasonably avoided; plus

                  (iii)  The worth at the time of award of the amount by which
     the unpaid rent for the balance of the Lease Term after the time of award
     exceeds the amount of such rental loss that Tenant proves could have been
     reasonably avoided; plus

                  (iv)   Any other amount reasonably necessary to compensate
     Landlord for all the detriment proximately caused by Tenant's failure to
     perform its obligations under this Lease or which in the ordinary course of
     things would be likely to result therefrom, specifically including but not
     limited to, brokerage commissions and advertising expenses incurred,
     expenses of remodeling the Premises or any portion thereof for a new
     tenant, whether for the same or a different use, and any special
     concessions made to obtain a new tenant; and

                  (v)    At Landlord's election, such other amounts in addition
     to or in lieu of the foregoing as may be permitted from time to time by
     applicable law.

The term "rent" as used in this Section 19.2 shall be deemed to be and to mean
all sums of every nature required to be paid by Tenant to Landlord pursuant to
the terms of this Lease.  As used in Paragraphs 19.2.1(i) and (ii), above, the
"worth at the time of award" shall be computed by allowing interest at the rate
set forth in Article 25 of this Lease, but in no case greater than the maximum
amount of such interest permitted by law.  As used in Paragraph 19.2.1(iii)
above, the "worth at the time of award" shall be computed by discounting such
amount at the discount rate of the Federal Reserve Bank of San Francisco at the
time of award plus one percent (1%).

          19.2.2  Landlord shall have the remedy described in California Civil
Code Section 1951.4 (lessor may continue lease in effect after lessee's breach
and abandonment and recover rent as it becomes due, if lessee has the right to
sublet or assign, subject only to reasonable limitations).  Accordingly, if
Landlord does not elect to terminate this Lease on account of any default by
Tenant, Landlord may, from time to time, without terminating this Lease, enforce
all of its rights and remedies under this Lease, including the right to recover
all rent as it becomes due.

     19.3 Sublessees of Tenant.  In the event Landlord elects to terminate this
          --------------------                                                 
Lease on account of any Event of Default by Tenant Landlord shall have the right
to terminate any and all subleases, licenses, concessions or other consensual
arrangements for possession entered into by Tenant and affecting the Premises or
may, in Landlord's sole discretion, succeed to Tenant's interest in such
subleases, licenses, concessions or arrangements.  In the event of Landlord's
election to succeed to Tenant's interest in any such subleases, licenses,
concessions or arrangements, Tenant shall, as of the 

                                       33

date of notice by Landlord of such election, have no further right to or
interest in the rent or other consideration receivable thereunder.

     19.4 Waiver of Default.  No waiver by Landlord or Tenant of any violation
          -----------------                                                   
or breach of any of the terms, provisions and covenants herein contained shall
be deemed or construed to constitute a waiver of any other or later violation or
breach of the same or any other of the terms, provisions, and covenants herein
contained.  Forbearance by Landlord or Tenant in enforcement of one or more of
the remedies herein provided upon an Event of Default shall not be deemed or
construed to constitute a waiver of such default.  The acceptance of any Rent or
other payment hereunder by Landlord or Tenant following the occurrence of any
default, whether or not known to Landlord or Tenant, as the case may be, shall
not be deemed a waiver of any such default, except only a default in the payment
of the Rent or other payment so accepted.

     19.5 Efforts to Relet.  For the purposes of this Article 19, neither this

by efforts of Landlord to relet the Premises, by its acts of maintenance or
preservation with respect to the Premises, or by appointment of a receiver to
protect Landlord's interests hereunder.  The foregoing enumeration is not
exhaustive, but merely illustrative of acts which may be performed by Landlord
without terminating this Lease or Tenant's right to possession.

in this Lease, Landlord shall be in default in the performance of any obligation
required to be performed by Landlord pursuant to this Lease if (i) Landlord is
obligated to make a payment of money to Tenant, and Landlord fails to pay such
unpaid amounts within ten (10) days of written notice from Tenant that the same
was not paid when due, or (ii) such failure is other than the obligation to pay
money, and Landlord fails to perform such obligation within thirty (30) days
after the receipt of notice from Tenant specifying in detail Landlord's failure
to perform; provided, however, if the nature of Landlord's obligation is such
that more than thirty (30) days are required for its performance, then Landlord
shall not be in default under this Lease if it shall commence such performance
within such thirty (30) day period and thereafter diligently pursue the same to
completion.  Upon any such default by Landlord under this Lease, Tenant may,
except as otherwise specifically provided in this Lease to the contrary,
exercise any of its rights provided at law or in equity; provided that, except
as otherwise specifically provided in this Lease to the contrary, Tenant shall
have no right to terminate this Lease.  Any award from a court or arbitrator in
favor of Tenant requiring payment by Landlord which is not paid by Landlord
within the time period directed by such award, may be offset by Tenant from Base
Rent and Additional Rent next due and payable under this Lease.

responsible for the cost of the design, permitting, construction and
installation of the Monument Sign and Tenant Name (the "Sign Cost"), and shall

Monument Sign (or from the sign itself, but without restoration obligations) as
of the expiration or earlier termination of the Lease.  Tenant acknowledges and
agrees that the Monument Sign shall be subject to all necessary approvals and
permits from governmental agencies and shall comply with the CC&Rs.

the Building Signage in first class condition during the Lease Term.  In

the Building Signage as of the termination or earlier expiration of the Lease

notice by Landlord at the sole expense of Tenant.  Any signs, window coverings,

coverings for the Building), or other items visible from the exterior of the
Premises or Building are subject to the prior approval of Landlord, in its sole
but reasonable discretion.

     Neither Landlord nor Tenant shall do anything in or about the Premises
which will in any way conflict with any law, statute, ordinance or other
governmental rule, regulation or requirement now in force or which may hereafter
be enacted or promulgated (collectively, "Laws").  Should any Laws now or
hereafter be imposed on Landlord or Tenant by a state, federal or local
governmental body charged with the establishment, regulation and enforcement of
occupational, health or safety standards for employers, employees or tenants,
then (i) Tenant agrees, at its sole cost and expense, to comply promptly with
such Laws if they relate to any of the Tenant Maintenance Items, the Tenant
Improvements or the Alterations and to make all alterations to the Premises,
Building, and/or Real Property as are required to comply with such Laws and (ii)
Landlord shall comply with and all other Laws, including those which relate to
the Landlord Maintenance Items, unless such compliance obligations are triggered
by the construction of the Tenant Improvements or Alterations, in which 

                                       36

                                 ------------

     Each party hereby acknowledges that late payment by the other of Rent or
other sums due hereunder will cause such party to incur costs not contemplated
by this Lease, the exact amount of which is extremely difficult to ascertain.
Such costs include, but are not limited to, processing and accounting charges,
and late charges which may be imposed upon Landlord by the terms of any
mortgage, deed of trust, or ground or underlying lease covering the Premises.
Accordingly, if any installment of Rent or any other sum due from either party
shall not be received by the other within five (5) business days after notice
that said amount is over due, then the defaulting party shall pay to the other a
late charge equal to two percent (2.0%) of the amount due, provided that three
(3) times in any twenty-four (24) month period, Landlord shall first deliver a
second five (5) business day notice prior to such late charge becoming due.  The
parties hereby agree that such late charge represents a fair and reasonable
estimate of the costs that will be incurred by reason of such late payment.
Acceptance of such late charge shall in no event constitute a waiver of any
default with respect to such overdue amount, nor prevent the non-defaulting
party from exercising any of the other rights and remedies granted hereunder.
Any late charge owed by Tenant shall be deemed Additional Rent and the right to
require it shall be in addition to all of Landlord's other rights and remedies
hereunder or at law other than for damages for the late payment of Rent.  In
addition to the late charge described above, any Rent or other amounts owing
hereunder which are not paid within five (5) business days after notice the same
are over due shall thereafter bear interest until paid at a rate (the "Interest
Rate") per annum equal to the Wells Fargo Bank (or other "money center" national
bank reasonably selected by Landlord) "reference rate" or "base rate" publicly
announced from time to time, plus two percent (2%), provided that in no case
shall such rate be higher than  the highest rate permitted by applicable law.

Lease, all covenants and agreements to be kept or performed by Tenant under this
Lease shall be performed by Tenant at Tenant's sole cost and expense and without
any reduction of Rent.  If Tenant shall fail to perform any of its obligations
under this Lease within a reasonable time after such performance is required by
the terms of this Lease, Landlord may, but shall not be obligated to, after
thirty (30) days prior notice to Tenant (or in the case of an emergency, after
such notice as is reasonable under the circumstances), make any such payment or
perform any such act on Tenant's part without waiving its right based upon any
default of Tenant and without releasing Tenant from any obligations hereunder.

     26.2 Tenant's Reimbursement.  Except as may be specifically provided to the

incurred by Landlord in connection with the remedying by Landlord of Tenant's
defaults pursuant to the provisions of Section 26.1. Tenant's obligations under
this Section 26.2 shall survive the expiration or sooner termination of the
Lease Term.

                               ENTRY BY LANDLORD
                               -----------------

     Subject to the provisions of this Lease, and provided Landlord uses
commercially reasonable efforts to minimize any interference with Tenant's
business, Landlord reserves the right at all reasonable times and upon
reasonable notice to the Tenant (or in the case of an emergency upon such notice
as is reasonable under the circumstances) to enter the Premises to (i) inspect
them; (ii) show the Premises to prospective purchasers, mortgagees or tenants,
ground or underlying lessors or insurers (provided that such right shall not
extend to prospective tenants until twelve (12) months prior to the Lease
Expiration Date); (iii) post notices of nonresponsibility; or (iv) alter,
improve or repair the Premises or the Building if necessary to comply with Laws,
or for alterations, repairs or improvements to the Landlord Maintenance Items.
Notwithstanding anything to the contrary contained in this Article 27, and
subject to the notice requirements set forth in Section 19.1.2, above, and
Landlord's compliance with the terms of Section 26.1, Landlord may enter the
Premises at any time to perform any covenants of Tenant which Tenant fails to
perform.  Except as otherwise expressly provided in this Lease, any such entries
shall be without the abatement of Rent and shall include the right to take such
reasonable steps as required to accomplish the stated purposes.  Tenant hereby
waives any claims (not including claims for physical property damages (subject
to Section 10.4 hereof) or personal injury damages) for any injuries or
inconvenience to or interference with Tenant's business or lost profits,
occasioned thereby.  For each of the above purposes, Landlord shall at all times
have a key with which to unlock all the doors in the Premises, excluding
Tenant's vaults, safes and special security areas designated in advance by
Tenant.  In an emergency, Landlord shall have the right to use any means that
Landlord may in good faith deem proper to open the doors in and to the Premises.
Subject to the provisions of this Lease, any entry into the Premises by Landlord
in the manner hereinbefore described shall not be deemed to be a forcible or
unlawful entry into, or a detainer of, the Premises, or an actual or
constructive eviction of Tenant from any portion of the Premises.
Notwithstanding the foregoing, as reasonably necessary in connection with
Tenant's business use of the Premises, Tenant may designate certain secure
areas, and on prior written notice to Landlord of these areas, Tenant may deny
Landlord access to such areas except in an emergency or when Landlord is
accompanied by Tenant.  Subject to the provisions of this Lease, no provision of
this Lease shall be construed as obligating Landlord to perform any repairs,
alterations or decorations except as otherwise expressly agreed to be performed
by Landlord herein.

     Prior to the Lease  Commencement Date, Landlord will construct on the Real

Landlord and of Tenant, but also of their respective successors or assigns,
provided this clause shall not permit any assignment by Tenant contrary to the
provisions of Article 14 of this Lease.

     29.3 No Air Rights.  No rights to any view or to light or air over any

Tenant by this Lease.

     29.4 Modification of Lease.  Should any prospective mortgagee or ground

lessor for the Building or Real Property require a modification or modifications
of this Lease, which modification or modifications will not directly or
indirectly cause an increased cost or expense to Tenant under this Lease or in
connection with Tenant's business operations, or have any negative economic
impact, or any other material negative impact, on the Premises or Tenant's
occupancy of the Premises or in any other way adversely change the rights and
obligations of Tenant hereunder including, without limitation, all rights and
obligations of Tenant with respect to renewal, assignment and subletting,
insurance proceeds and Tenant's rights to terminate this Lease, or receive
abatement of Rent, then and in such event, Tenant agrees that this Lease may be
so modified at Landlord's sole cost and expense (including Tenant's reasonable
attorneys' fees for review of the same), and agrees to execute whatever
reasonable documents are required therefor and deliver the same to Landlord
within thirty (30) days following the request therefor.  Should Landlord or any
such prospective mortgagee or ground lessor require execution of a short form of
Lease for recording, containing, among other customary provisions, the names of
the parties, a description of the Premises and the Lease Term, Tenant agrees to
execute such short form of Lease and to deliver the same to Landlord within
fifteen (15) business days following Tenant's receipt of written request
therefor.

     29.5 Transfer of Landlord's Interest.  Notwithstanding the provisions of
          -------------------------------

financial obligations with respect thereto.  Tenant acknowledges that Landlord
has the right to transfer all or any portion of its interest in the Real
Property and Building and in this Lease.  Tenant agrees that in the event of a
transfer of fee title and provided that such transferee is a bona fide purchaser
and agrees in writing to perform all of Landlord's obligations thereafter
accruing, Landlord shall automatically be released from all liability under this
Lease thereafter accruing and Tenant agrees to look solely to such transferee
for the performance of Landlord's obligations hereunder arising or accruing
after the date of transfer upon agreement by such transferee 

                                       39
<PAGE>
 
to fully assume and be liable for all obligations of this Lease to be performed
by Landlord which first accrue or arise after the date of the conveyance, and
Tenant shall attorn to such transferee. Tenant further acknowledges that
Landlord may assign its interest in this Lease to a mortgage lender as
additional security and agrees that such an assignment shall not release
Landlord from its obligations hereunder and that unless and until such mortgage
lender succeeds to Landlord's interest and obligations hereunder, Tenant shall
continue to look to Landlord for the performance of its obligations hereunder.

     29.6   Prohibition Against Recording.  A memorandum of this Lease may be
            -----------------------------

same, within ten (10) business days after the expiration or earlier termination
of this Lease and provided Tenant will pay all costs of such recordation.

     29.7   Landlord's Title.  Subject to and except for the rights of Tenant
            ----------------                                                 
expressly set forth in this Lease, Landlord's title is and always shall be
paramount to the title of Tenant, and nothing herein contained shall empower
Tenant to do any act which can, shall or may encumber the title of Landlord.

Property and to the proceeds of any insurance (the cost of which is included in
Operating Expenses) or condemnation

and (ii) subject to the waiver of consequential damages set forth in Section

personal liability therefor, and Tenant hereby expressly waives and releases
such personal liability on behalf of itself and all persons claiming by, through
or under Tenant; provided, however, if Landlord incurs any liability to Tenant
under this Lease which liability is reduced to a judgment against Landlord, then
Tenant shall be entitled to deduct the amount of such judgment from Rent payable
by Tenant under this Lease. The limitations of liability contained in this
Section 29.13 shall inure to the benefit of Landlord's and the Landlord Parties'

lease, and it is not effective as a lease or otherwise until execution and
delivery by both Landlord and Tenant.

     29.20  Brokers.  Landlord and Tenant hereby warrant to each other that they
            -------                                                             
have had no dealings with any real estate broker or agent in connection with the
negotiation of this Lease, excepting only the real estate broker specified in

(90) day period to the claim by Broker, the offset rights in this Section 29.20
shall be limited to the amount ultimately determined to be owed by Landlord to
such Broker.

            If at the time of renewal or extension of the term of this Lease,
the Brokerage Agreement between Landlord and Broker provides that Landlord is
not obligated to pay a commission to Broker if Tenant presents to Landlord
and/or Broker a written exclusive listing agreement with another broker, then in
the event that (i) Landlord or its successor in interest is otherwise obligated
to pay a commission to Broker pursuant to the terms of the Brokerage Agreement
as the result of any renewal or extension of the term of this Lease, and (ii)
Tenant uses a broker other than Broker in connection with such renewal or
extension of the term of this Lease and such use is not pursuant to such written
exclusive listing agreement with another broker, then Tenant shall be obligated
to pay any fee, commission or other compensation to such broker and Tenant's
indemnity obligation to Landlord, as set forth in this Section 29.20, shall

to the contrary, be entitled (i) to make any repairs or perform any acts
hereunder at Landlord's expense or (ii) to any setoff of the Rent or other
amounts owing hereunder against Landlord; provided, however, that the foregoing
shall in no way impair the right of Tenant to commence a separate action against
Landlord for any violation by Landlord of the provisions hereof so long as, to
the extent required in this Lease, notice is first given to Landlord and an
opportunity is granted to Landlord to correct such violations as provided in
Section 19.5, above.

     29.22  Year 2000 Compliance Obligations.  Landlord shall ensure that all
            --------------------------------

                               GURANTY OF LEASE

                                      BY

                  MATSUSHITA ELECTRIC CORPORATION OF AMERICA
<PAGE>
 
                               GUARANTY OF LEASE

     THIS GUARANTY OF LEASE ("Guaranty") is executed as of February 18, 1999 by
MATSUSHITA ELECTRIC CORPORATION OF AMERICA, a Delaware corporation
("Guarantor"), whose address is 1 Panasonic Way, Secaucus, New Jersey 07094 for
the benefit of Wells Operating Partnership, L.P., a Delaware limited partnership
("Landlord"), whose address is 3885 Holcomb Bridge Road, Norcross, Georgia
30092, with reference to the following facts:

     A.  Landlord and Matsushita Avionics Systems  Corporation, a Delaware
corporation ("Tenant") intend to enter into that certain Office Lease dated as
of February 18, 1999 (the "Lease') pursuant to which Tenant shall lease from
Landlord the real property described in the Lease;

     B.  As a condition to Landlord's execution of the Lease, Landlord requires
that the undersigned guaranty the full and timely performance of the obligations
of Tenant under said Lease; and

     C.  The undersigned desires that Landlord enter into the Lease with Tenant.
Capitalized terms not expressly defined herein shall have the definitions set
forth in the Lease.

     NOW, THEREFORE, in consideration of the execution of the Lease by Landlord,
and for other good and valuable consideration, the receipt and sufficiency of
which are hereby acknowledged, the parties hereto agree as follows:

     1.  Guarantor unconditionally guaranties, without deduction by reason of
setoff, defense or counterclaim, to Landlord and its successors and assigns the
full and punctual payment, and the performance and observance by Tenant, of all
sums, terms, covenants and conditions in the Lease to be paid, kept, performed
or observed by Tenant.

     2.  If Tenant shall at any time default in the performance or observance of
any of the terms, covenants or conditions of the Lease to be kept, performed or
observed by Tenant, Guarantor will keep, perform and observe same, as the case
may be, in the place and stead of Tenant.  Guarantor has the right to cure any
default of Tenant, provided such cure is performed in accordance with the terms
and within the time periods set forth in the Lease.  Notice of default shall be
given to Guarantor, it being specifically agreed and understood that the
guarantee of the undersigned is a continuing guarantee under which Landlord may
proceed immediately against Tenant or Guarantor following any breach or default
by Tenant or for the enforcement of any rights which Landlord may have as
against Tenant pursuant to or under the terms of the Lease or at law or in
equity.

      3.  Any act or omission of Landlord, or of its successors or assigns,
constituting a waiver of any of the terms or conditions of the Lease (including,
without limitation, concerning any consent required under the Lease); or the
granting of any indulgences or extensions of time to Tenant, may be done without
notice to Guarantor and without releasing Guarantor from any of its obligations
hereunder.
<PAGE>
 
     4. The obligations of Guarantor hereunder shall not be released by
Landlord's receipt, application or release of any security given for the
performance and observance of any covenant or condition of the Lease to be
performed or observed by Tenant, nor by any modification of the Lease,
regardless of whether Guarantor consents thereto or receives notice thereof.

     5. The liability of Guarantor hereunder shall in no way be affected by (a)
the release or discharge of Tenant in any creditor's receivership, bankruptcy or
other proceeding; (b) the impairment, limitation or modification of the
liability of Tenant or the estate of Tenant in bankruptcy, or of any remedy for
the enforcement of Tenant's liability under the Lease resulting from the
operation of any present or future provision of any federal or state bankruptcy
or insolvency law or other statute or from the decision of any court; (c) the
rejection or disaffirmance of the Lease in any such proceedings; (d) the
assignment or transfer of the Lease by Tenant; (e) any disability or other
defense of tenant; (f) the cessation from any cause whatsoever of the liability
of Tenant; (g) the exercise by Landlord of any of its rights or remedies
reserved under the Lease or by law; or (h) any termination of the Lease.

     6.  Guarantor further agrees that it may be joined in any action against
Tenant in connection with the obligations of Tenant and recovery may be had
against Guarantor in any such action.  Landlord may enforce the obligations of
Guarantor hereunder without first taking any action whatsoever against Tenant or
its successors and assigns, or pursue any other remedy or apply any security it
may hold, and Guarantor hereby waives (a) notice of acceptance of this Guaranty,
(b) demand of payment, presentation and protest, (c) all right to assert or
plead any statute of limitations relating to this Guaranty and/or the Lease, (d)
any right to require Landlord to proceed against Tenant or any other guarantor
or any other person or entity liable to Landlord, (e) any right to require
Landlord to apply to any default any security deposit or other security it may
hold under the Lease, (f) any right to require Landlord to proceed under any
other remedy Landlord may have before proceeding against Guarantor, (g) any
right of subrogation, and (h) and any and all surety or other defenses in the
nature thereof including, without limitation, the provisions of California Civil
Code Section 2918 and 2845 or any similar, related or successor provisions of
law.

     7.  This Guaranty shall apply to the Lease, any extension, renewal,
modification or amendment thereof, and to any assignment, subletting or other
tenancy thereunder or to any holdover term following the term granted under the
Lease or any extension or renewal thereof; provided, however, that with respect
to any assignment to other than an Affiliate, this guaranty shall not apply to
any modification or amendment to the Lease made after such an assignment solely
to the extent of any additional obligations or modifications to existing
obligations.  It is specifically agreed and understood that the terms of the
Lease may be altered, affected, modified or changed by agreement between
Landlord and Tenant, or by a course of conduct, and said Lease may be assigned
by Landlord or any assignee of Landlord without consent or notice to Guarantor
and that this Guaranty shall thereupon and thereafter guaranty the performance
of said Lease as so changed, modified, altered or assigned.

     8. In the event this Guaranty shall be held ineffective or unenforceable by
any court of competent jurisdiction or in the event of any limitation of
Guarantor's liability hereunder other than as expressly provided herein, then
Guarantor shall be deemed to be a tenant under the Lease with the same force and
effect as if Guarantor were expressly named as a joint and several tenant
therein.

     9. In the event of any litigation between Guarantor and Landlord with
respect to the subject matter hereof, the unsuccessful party to such litigation
agrees to pay to the successful party all fees, costs and expenses thereof,
including reasonable attorneys' fees and expenses.

     10.  No delay on the part of Landlord in exercising any right hereunder or
under the Lease shall operate as a waiver of such right or of any other right of
Landlord under the Lease or hereunder, nor shall any delay, omission or waiver
on any one occasion be deemed a bar to or a waiver of the same or any other
right on any future occasion.  This Guaranty shall not be released, modified or
affected by failure or delayed on the part of Landlord to enforce any of the
rights or remedies of Tenant under the Lease, whether pursuant to the terms
thereof or at law or in equity.

     11. If there is more than one undersigned Guarantor, the term Guarantor, as
used herein, shall include all of the undersigned; each and every provision of
this Guaranty shall be binding on each and every one of the undersigned; they
shall be jointly and severally liable hereunder; and Landlord shall have the
right to join one or all of them in any proceeding or to proceed against them in
any order.

     12.  This instrument constitutes the entire agreement between Landlord and
Guarantor with respect to the subject matter hereof, superseding all prior oral
or written agreements or understandings with respect thereto and may not be
changed, modified, discharged or terminated orally or in any manner other than
by an agreement in writing signed by Guarantor and Landlord.

     13. This Guaranty shall be governed by and construed in accordance with the
laws of the State of California. The parties further agree that venue shall be
proper in the Superior Court or federal district court for Orange County,
California, in the event of any litigation between the parties with respect to
this Guaranty.

     14. All notices or other communications required or permitted hereunder
shall be in writing, and shall be personally delivered or sent either to
Guarantor at the address set forth on Page 1 hereof to the attention of V.P. -
Facilities with a copy to the same address to the attention of General Counsel,
or to Landlord, at the address set forth on Page 1 hereof, by registered or
certified mail, postage prepaid, return receipt requested, by personal delivery
or by nationally recognized overnight courier service and shall be deemed
received upon the earlier of (i) if personally delivered, the date of delivery
to the address of the person to receive such notice; (ii) if mailed, four (4)
business days after the date of posting by the United States Post Office; or
(iii) if delivered by overnight courier, the date of receipt as confirmed by the

     15. If Landlord desires to sell, finance or refinance the "Building" or the
"Premises" (as such terms are defined in the Lease), or any part thereof,
Guarantor hereby agrees to deliver to any lender or buyer designated by Landlord
such estoppel statements of Guarantor as may be reasonably required by such
lender or buyer. All such statements shall be received by any such lender or
buyer in confidence and shall be used only for the foregoing purposes, and such
lender or buyer shall 


                                       3
<PAGE>
 
acknowledge the same to Guarantor in writing (should Guarantor require such an
acknowledgment) as a precondition to Guarantor's obligations under this
Paragraph 15.  In addition, Guarantor shall not be obligated to deliver estoppel
statements hereunder more frequently than two (2) times in any calendar year.

     16.  The term "Landlord" whenever hereinabove used refers to and means the
Landlord in the Lease specifically named and also any assignee of said Landlord,
whether by outright assignment or by assignment for security, and also any
successor to the interest of said Landlord of any assignee in such Lease or any
part thereof, whether by assignment or otherwise.  So long as the Landlord's
interest in or to the leased premises or the rents, issues and profits
therefrom, or in, to or under said Lease, are subject to any mortgage or deed of
trust or assignment for security, no acquisition by Guarantor of Landlord's
interest in the leased premises or under said Lease shall affect the continuing
obligation of Guarantor under this Guarantee which shall nevertheless continue
in full force and effect for the benefit of the mortgagee, beneficiary, trustee
or assignee under such mortgage, deed of trust or assignment, or any purchase at
sale by judicial foreclosure or under private power of sale, and of the
successors and assigns of any such mortgagee, beneficiary, trustee, assignee or
purchaser.

     The term "Tenant" wherever hereinabove used refers to and means the Tenant
in the foregoing Lease specifically named and also any assignee or sublessee of
said Lease and also any successor to the interests of said Tenant, assignee or
sublessee of such Lease or any part thereof, whether by assignment, sublease or
otherwise.

     IN WITNESS WHEREOF, Guarantor has executed this Guaranty as of the date
first above written.

                       RENTAL INCOME GUARANTY AGREEMENT

                   BETWEEN WELLS OPERATING PARTNERSHIP, L.P.

                                      AND

                       FUND VIII AND FUND IX ASSOCIATES
<PAGE>
 
                       RENTAL INCOME GUARANTY AGREEMENT


  THIS RENTAL INCOME GUARANTY AGREEMENT is made and entered into as of the 18th
day of February, 1999, by and between WELLS OPERATING PARTNERSHIP, L.P., a
Delaware limited partnership ("Wells OP"), and FUND VIII AND FUND IX ASSOCIATES,
a Georgia joint venture between Wells Real Estate Fund VIII, L.P. and Wells Real
Estate Fund IX, L.P. (the "Fund VIII-IX Joint Venture").

                             W I T N E S S E T H :

  WHEREAS, the Fund VIII-IX Joint Venture is currently the landlord pursuant to
the terms of that certain Office Lease dated April 29, 1996 (the "Existing
Matsushita Lease"), with Matsushita Avionics Systems Corporation ("Matsushita")
pursuant to which Matsushita is the tenant currently occupying that certain
building owned by the Fund VIII-IX Joint Venture located at 15253 Bake Parkway,
Irvine, California (the "Bake Parkway Building"); and

  WHEREAS, Wells OP desires to enter into a new lease with Matsushita for an
approximately 150,000 square foot building to be located on certain property in
Lots 8 and 9 of the Pacific CommerceCentre Park in Lake Forest, Orange County,
California (the "New Matsushita Lease"); and

  WHEREAS, as a condition to entering into a New Matsushita Lease, Matsushita is
requiring that the Fund VIII-IX Joint Venture release it from its obligations as
tenant under the Existing Matsushita Lease and, in connection therewith, the
Fund VIII-IX Joint Venture has been requested to enter into and execute a Lease
and Guaranty Termination Agreement with Matsushita; and

  WHEREAS, as a condition for the Fund VIII-IX Joint Venture releasing
Matsushita from its obligations as tenant under the Existing Matsushita Lease,
the Fund VIII-IX Joint Venture is requiring Wells OP to guaranty that it will
receive rental income at least equal to the rent and building expenses it would
have received over the remaining term of the Existing Matsushita Lease, pursuant
to the terms and provisions of this Rental Income Guaranty Agreement.

  NOW, THEREFORE, in consideration of the premises, and other good and valuable
consideration in hand paid, the receipt and sufficiency of which are hereby
acknowledged, and in consideration of the Fund VIII-IX Joint Venture executing
and entering into that certain Lease and Guaranty Termination Agreement with
Matsushita of even date herewith releasing Matsushita from its obligations as
tenant under the Existing Matsushita Lease, the parties hereto, intending to be
legally bound, hereby agree as follows:

                                       1
<PAGE>
 
  1.  Rental Income Guaranty.  In consideration for the release by the Fund
      ----------------------                                               
VIII-IX Joint Venture of Matsushita from its obligations as tenant under the
Existing Matsushita Lease and the execution by the Fund VIII-IX-X Joint Venture
of that certain Lease and Guaranty Termination Agreement of even date herewith,
Wells OP hereby guaranties and agrees to pay to the Fund VIII-IX Joint Venture
such amounts as may be necessary or required so that the Fund VIII-IX Joint
Venture shall continue to receive "Monthly Cash Flow," as defined below, at
least equal to the rent and building expenses that the Fund VIII-IX Joint
Venture would have received over the remaining term of the Existing Matsushita
Lease, calculated on a cumulative basis over the remaining term of the Existing
Matsushita Lease. As used herein, the term "Monthly Cash Flow" shall mean either
(i) the aggregate of all rents received on leases for leasing some or all of the
Bake Parkway Building, or (ii) in the case a joint venture with Wells OP is
formed in the future, as contemplated by paragraph 3 below, the amount of cash
flow distributions received by the Fund VIII-IX Joint Venture from said new
joint venture. It is the intent of the foregoing rental income guaranty that the
release by the Fund VIII-IX Joint Venture of Matsushita's current lease
obligations under the Existing Matsushita Lease will not result in a direct
economic detriment to the Fund VIII-IX Joint Venture.

  2.  Agreement to Fund Deficit.  In the event that the amount of "Monthly Cash
      -------------------------                                                
Flow," as defined in paragraph 1 above, is not at least equal to the rent and
building expenses that the Fund VIII-IX Joint Venture would have received over
the remaining term of the Existing Matsushita Lease, calculated on a cumulative
basis over the remaining term of the Existing Matsushita Lease, Wells OP shall
pay the Fund VIII-IX Joint Venture such amounts as may be required to make up
such deficit.

  3.  Potential Joint Venture.  In the event that the Fund VIII-IX Joint Venture
      -----------------------                                                   
obtains one or more new tenants for the Bake Parkway Building and, in connection
therewith, additional capital is required for tenant improvements, brokerage
fees or other purposes, the Fund VIII-IX Joint Venture and Wells OP may agree,
in the sole discretion of both parties and, in the case of Wells OP, only after
approval of a majority of the Independent Directors of Wells Real Estate
Investment Trust, Inc., the general partner of Wells OP, to form a joint venture
to accomplish the funding of such amounts. In such event, it is anticipated that
distributions payable out of said joint venture would be made in accordance with
the relative capital contributions of the parties, provided that the guaranty of
Wells OP that the Funds VIII-IX Joint Venture would continue to receive "Monthly
Cash Flow" at least equal to the rent and building expenses that the Fund VIII-
IX Joint Venture would have received over the remaining term of the Existing
Matsushita Lease, calculated on a cumulative basis, would continue and, as set
forth above, would instead be applicable to the amount of cash flow
distributions received by the Fund VIII-IX Joint Venture from said newly formed
joint venture.

  4.  Term.  The term of this Agreement and Wells OP's obligations hereunder
      ----                                                                  
shall terminate upon the earlier of: (i) the expiration of the remaining term of
the Existing Matsushita Lease, which expires in September 2003; or (ii) the
written consent of both parties hereto to terminate this Agreement.

                                       2

amendment, termination or attempted waiver shall be valid unless in writing and
signed by the party sought to be bound.

  6.  Notice.  Any and all notices, offers, demands or elections required or
      ------

each of which shall be deemed an original, but all of which together shall
constitute one and the same Agreement.

  9.  Further Acts.  Each party agrees to perform any further acts and to
      ------------                                                       
execute and deliver any instruments or documents that may be necessary or
reasonably deemed advisable to carry out the purposes of this Agreement.

  10. No Third Party Beneficiary.  The terms of this Agreement are intended to
      --------------------------                                              
benefit only the parties hereto, and no third party shall have any right to
enforce any of the terms or provisions hereof.

  11. Severability.  If any part of this Agreement shall be held void, voidable
      ------------                                                             
or otherwise unenforceable by any court of law or equity, nothing contained in
this Agreement shall limit the enforceability of any other part.

  12. Successors and Assigns.  This Agreement shall be binding upon and shall
      ----------------------                                                 
inure to the benefit of the parties hereto and their respective successors and
assigns.  No party shall have the right to assign this Agreement, or any
interest under this Agreement, without the prior written consent of the other
party.
