1. Organization, Formation and Structure

Organization

      Saul Centers, Inc. ("Saul Centers") was incorporated under the Maryland
General Corporation Law on September 10, 1993. The authorized capital stock of
Saul Centers consists of 30,000,000 shares of common stock, having a par value
of $0.01 per share and 1,000,000 shares of preferred stock. Each holder of
common stock is entitled to one vote for each share held. Saul Centers, together
with its wholly owned subsidiaries and the limited partnerships of which Saul
Centers or one of its subsidiaries is the sole general partner, are referred to
collectively as the "Company". Saul Centers operates as a real estate investment
trust under the Internal Revenue Code of 1986, as amended (a "REIT").

Formation and Structure of Company

      Saul Centers was formed to continue and expand the shopping center
business previously owned and conducted by the B.F. Saul Real Estate Investment
Trust, the B.F. Saul Company, Chevy Chase Bank, F.S.B. and certain other
affiliated entities (collectively, "The Saul Organization"). On August 26, 1993,
The Saul Organization transferred to Saul Holdings Limited Partnership, a newly
formed Maryland limited partnership (the "Operating Partnership"), and two newly
formed subsidiary limited partnerships (the "Subsidiary Partnerships") 26
shopping center properties, one office property, one research park and one
office/retail property and the management functions related to the transferred
properties. Since its formation, the Company has purchased three additional
community and neighborhood shopping center properties, an office property and
purchased a land parcel which it developed into a community shopping center. The
Company is currently in the predevelopment and approval process of converting an
under-performing shopping center to an industrial / warehouse use. Therefore, as
of March 31, 1999, the Company's properties (the "Current Portfolio Properties")
consisted of 29 operating shopping center properties (the "Shopping Centers"), a
property planned to be converted to an industrial / warehouse facility (the
"Industrial Property") and four predominantly office properties (the "Office
Properties"). To facilitate the placement of collateralized mortgage debt, the
Company established Saul QRS, Inc. and SC Finance Corporation, each of which is
a wholly owned subsidiary of Saul Centers. Saul QRS, Inc. was established to
succeed to the interest of Saul Centers as the sole general partner of Saul
Subsidiary I Limited Partnership.

      As a consequence of the transactions constituting the formation of the
Company, Saul Centers serves as the sole general partner of the Operating
Partnership and of Saul Subsidiary II Limited Partnership, while Saul QRS, Inc.,
Saul Centers' wholly owned subsidiary, serves as the sole general partner of
Saul Subsidiary I Limited Partnership. The remaining limited partnership
interests in Saul Subsidiary I Limited Partnership and Saul Subsidiary II
Limited Partnership are held by the Operating Partnership as the sole limited
partner. Through this structure, the Company owns 100% of the Current Portfolio
Properties.

2. Summary of Significant Accounting Policies

Nature of Operations

      The Company, which conducts all of its activities through its
subsidiaries, the Operating Partnership and Subsidiary Partnerships, engages in
the ownership, operation, management, leasing, acquisition, renovation,
expansion, development and financing of community and neighborhood shopping
centers and office properties, primarily in the Mid-Atlantic region.

      A majority of the Shopping Centers are anchored by several major tenants.
Eighteen of the 29 Shopping Centers are anchored by a grocery store and offer
primarily day-to-day necessities and services. As of December 1998, no single
shopping center accounted for more than 11.4% of the total shopping center gross
leasable area. Only one retail tenant, Giant Food at 7.1%, accounted for more
than 1.7% of the Company's 1998 total revenues. No office tenant other than the
United States General Service Administration, at 10.4%, accounted for more than
1.8% of 1998 total revenues.

Principles of Consolidation

      The accompanying consolidated financial statements of the Company include
the accounts of Saul Centers, its subsidiaries, and the Operating Partnership
and Subsidiary Partnerships which are majority owned by Saul Centers. All
significant intercompany balances and transactions have been eliminated in
consolidation.

Real Estate Investment Properties

      Real estate investment properties are stated at the lower of depreciated
cost or fair value less cost to sell. Management believes that these assets have
generally appreciated in value and, accordingly, the aggregate current value
exceeds their aggregate net book value and also exceeds the value of the
Company's liabilities as reported in these financial statements. These financial
statements are prepared in conformity with generally accepted accounting
principles, and accordingly, do not report the current value of the Company's
real estate assets. Real estate investment properties are reviewed for potential
impairment losses whenever events or changes in circumstances indicate that the
carrying amount of an asset may not be recoverable. If the sum of an individual
property's undiscounted expected future cash flows is less than its carrying
amount, the Company's policy is to recognize an impairment loss measured by the
amount the depreciated cost of the property exceeds its fair value. Fair value
is calculated as the present value of expected future cash flows.

      Interest, real estate taxes and other carrying costs are capitalized on
projects under development and construction. Once construction is substantially
completed and the assets are placed in service, their rental income, direct
operating expenses and depreciation are included in 


                                       9

current operations. Expenditures for repairs and maintenance are charged to
operations as incurred. Interest expense capitalized during the three month
periods ended March 31, 1999 and 1998, was $133,000 and $34,000, respectively.

      A project is considered substantially complete and available for occupancy
upon completion of tenant improvements, but no later than one year from the
cessation of major construction activity. Substantially completed portions of a
project are accounted for as separate projects. Depreciation is calculated using
the straight-line method and estimated useful lives of 33 to 50 years for
buildings and up to 20 years for certain other improvements. Leasehold
improvements are amortized over the lives of the related leases using the
straight-line method.

Accounts Receivable and Accrued Income

      Accounts receivable primarily represent amounts currently due from tenants
in accordance with the terms of the respective leases. In addition, at March 31,
1999 accounts receivable included $1,472,000, representing minimum rental income
accrued on a straight-line basis to be paid by tenants over the terms of the
respective leases. Receivables are reviewed monthly and reserves are established
when, in the opinion of management, collection of the receivable is doubtful.
Accounts receivable in the accompanying financial statements are shown net of an
allowance for doubtful accounts of $718,000 at March 31, 1999.

Deferred Debt Costs

      Deferred debt costs consist of financing fees and costs incurred to obtain
long-term financing. These fees and costs are being amortized over the terms of
the respective loans or agreements. Deferred debt costs in the accompanying
financial statements are shown net of accumulated amortization of $693,000 at
March 31, 1999.

Revenue Recognition

      Rental and interest income is accrued as earned except when doubt exists
as to collectibility, in which case the accrual is discontinued. When rental
payments due under leases vary from a straight-line basis because of free rent
periods or stepped increases, income is recognized on a straight-line basis in
accordance with generally accepted accounting principles. Expense recoveries
represent property operating expenses billed to the tenants, including common
area maintenance, real estate taxes and other recoverable costs. Expense
recoveries are recognized in the period the expenses are incurred. Additional
rental income based on tenant's revenues ("percentage rent") is accrued at the
time a tenant reports sales exceeding a specified breakpoint.

                                   (Unaudited)

Income Taxes

      The Company made an election to be treated, and intends to continue
operating so as to qualify as a REIT under sections 856 through 860 of the
Internal Revenue Code of 1986, as amended, commencing with its taxable year
ending December 31, 1993. A REIT generally will not be subject to federal income
taxation on that portion of its income that qualifies as REIT taxable income to
the extent that it distributes at least 95% of its REIT taxable income to
stockholders and complies with certain other requirements. Therefore, no
provision has been made for federal income taxes in the accompanying financial
statements.

Per Share Data

      Per share data is calculated in accordance with SFAS No. 128, "Earnings
Per Share." The Company has no dilutive securities; therefore, basic and diluted
earnings per share are identical. Net income before minority interests is
presented on a fully converted basis, that is, assuming the limited partners
exercise their right to convert their partnership ownership into shares of Saul
Centers, and is computed using weighted average shares of 17,800,000 and
16,887,000, for the quarters ended March 31, 1999 and 1998, respectively. Per
share data relating to net income after minority interests is computed using
weighted average shares of 12,917,000 and 12,494,000, for the quarters ended
March 31, 1999 and 1998, respectively.

Reclassifications

      Certain reclassifications have been made to the prior year financial
statements to conform to the current year presentation. The reclassifications
have no impact on operating results previously reported.

Minority Interests - Holders of Convertible Limited Partner Units in the
Operating Partnership

      The Saul Organization has a 27.5% limited partnership interest,
represented by 4,925,000 convertible limited partnership units in the Operating
Partnership, as of March 31, 1999. These Convertible Limited Partnership Units
are convertible into shares of Saul Centers' common stock on a one-for-one
basis, provided the rights may not be exercised at any time that The Saul
Organization owns, directly or indirectly, in the aggregate more than 24.9% of
the outstanding equity securities of Saul Centers. The impact of The Saul
Organization's 27.5% limited partnership interest in the Operating Partnership
is reflected as minority interests in the accompanying financial statements.

Deferred Compensation and Stock Plan for Directors

     Saul Centers has established a Deferred Compensation and Stock Plan for
Directors (the "Plan"), for the benefit of its directors and their
beneficiaries.  A director may elect to defer all or part of his or her
director's fees to be earned subsequent to the election.  A director has the
option to have deferred director's fees paid in cash, in shares of common stock
or in a combination of cash and shares of common stock.  If the director elects
to have the deferred fees paid in stock, the number of shares allocated to the
director is determined based on the market value of the common stock on the day
the deferred director's fee was earned.  The Company has registered 70,000
shares for use under the Plan, all of which were authorized at March 31, 1999.
As of March 31, 1999, 59,000 shares had been credited to the directors' deferred
fee accounts.

  Each director that served on the Board of Directors of the Company as of
February 22, 1999, the record date for the Company's Annual Meeting of
Stockholders, received as additional compensation, an award of 100 shares of the
Company's common stock on April 23, 1999.  These shares may not be deferred and
are restricted from transfer by the directors for a period of twelve months
following the award date.
 
New Accounting Pronouncements

      In September 1997, the Financial Accounting Standards Board ("FASB")
issued Statement of Financial Accounting Standards ("SFAS") No. 130 "Reporting
Comprehensive Income" which establishes standards for the reporting and display
of comprehensive income in the Company's financial statements. The Company
adopted this standard in the first quarter of 1998. The Company had no
comprehensive income during the three month period ended March 31, 1999.

      In September 1997, the FASB issued SFAS No. 131 "Disclosures about
Segments of an Enterprise and Related Information" which establishes standards
for the way that public business enterprises report information about operating
segments in annual financial statements and requires that those enterprises
report selected information about operating segments in interim financial
reports issued to shareholders. It also established standards for related
disclosures about products and services, geographic areas, and major customers.
Disclosures required by this new standard are presented in Note 6.

      In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities" which establishes accounting and reporting
standards for derivative instruments and hedging activities. It requires that an
entity recognize all derivatives as either assets or liabilities in the balance
sheet and measure those instruments at fair value. SFAS 133 is effective for
fiscal years beginning after June 15, 1999. The Company doesn't own derivative
instruments nor does it engage in hedging activities, and therefore expects that
SFAS 133 will not have an impact on the Company's financial condition or its
results of operations.

Change In Accounting Method

      On May 21, 1998, the EITF discussed Issue 98-9 "Accounting for Contingent
Rent In Interim Financial Periods" and reached a consensus that lessors should
defer the accounting recognition of contingent rent, such as percentage rent,
until the specific tenant sales breakpoint is achieved. The Company's prior
accounting method, which was permitted under generally accepted accounting
principles, recognized percentage rent when a tenant's achievement of its sales
breakpoint was considered probable. This EITF consensus was implemented
retroactively to January 1, 1998, as a change in accounting method. The new
accounting method is not expected to materially affect the amount of percentage
rent income reported on an annual basis, but is expected to have an impact on
the recognition of percentage rent income reported on a quarterly basis by
increasing revenues the Company reports in the first and fourth quarters and
decreasing revenues reported in the second and third quarters. The change in
accounting method has no impact on the Company's cash flows. The comparative
three month period financial statements ending March 31, 1998 have not been
restated. Had the accounting method been retroactively applied, net income for
the three month period ended March 31, 1998 would have been $2,179,000.

3. Construction In Progress

      Construction in progress includes the costs of active development projects
and other predevelopment project costs. Development costs include direct
construction costs and indirect costs such as architectural, engineering,
construction management and carrying costs consisting of interest, real estate
taxes and insurance. Construction in progress balances as of March 31, 1999 and
December 31, 1998 are as follows:

4. Notes Payable

      Notes payable totaled $291.8 million at March 31, 1999, of which $271.2
million (92.9%) was fixed rate debt and $20.8 million (7.1%) was floating rate
debt. As of March 31, 1999, the Company had a $60 million unsecured revolving
credit facility with outstanding borrowings of $19.5 million and additional

5. Shareholders' Equity and Minority Interests

      These financial statements are prepared in conformity with generally
accepted accounting principles and accordingly do not report the current value
of the Company's real estate assets. The Shareholders' Equity reported on the
Consolidated Balance Sheets does not reflect any increase in the value resulting
from the difference between the current value and the net book value of the
Company's assets. Therefore, Shareholders' Equity reported on the Consolidated
Balance Sheets does not reflect the market value of stockholders' investment in
the Company.

      The Consolidated Statement of Operations for the three months ended March
31, 1999 includes a charge for minority interests of $1,921,000 consisting of
$1,381,000 related to The Saul Organization's share of the net income for the
1999 quarter and $540,000 related to distributions to minority interests in
excess of allocated net income for the 1999 quarter. The charge for the three
month period ended March 31, 1998 of $1,713,000 consists of $1,012,000 related
to The Saul Organization's share of net income for the 1998 quarter, and
$701,000 related to distributions to minority interests in excess of allocated
net income for the 1998 quarter.

Item 2. Management's Discussion and Analysis of Financial Condition and Results
        of Operations

General

      The following discussion is based primarily on the consolidated financial
statements of Saul Centers, Inc. ("Saul Centers") and, together with its wholly
owned subsidiaries and the limited partnerships of which it or one of its wholly
owned subsidiaries is the sole general partner (the "Company"), as of March 31,
1999 and for the three month period ended March 31, 1999.

Liquidity and Capital Resources

      The Company's principal demands for liquidity are expected to be
distributions to its stockholders, debt service and loan repayments, expansion,
renovation, and redevelopment of the Current Portfolio Properties and selective
acquisition and development of additional properties. In order to qualify as a
REIT for federal income tax purposes, the Company must distribute to its
stockholders at least 95% of its "real estate investment trust taxable income,"
as defined in the Internal Revenue Code of 1986, as amended. The Company
anticipates that operating revenues will provide the funds necessary for
operations, debt service, distributions, and required recurring capital
expenditures. Balloon principal repayments are expected to be funded by
refinancings.

      Management anticipates that during the current year the Company may: 1)
redevelop certain of the Shopping Centers, 2) develop additional freestanding
outparcels or expansions within certain of the Shopping Centers, 3) acquire
existing neighborhood and community shopping centers and/or office properties
and 4) develop new shopping center or office sites. Acquisition and development
of properties are undertaken only after careful analysis and review, and
management's determination that such property is expected to provide long-term
earnings and cash flow growth. During the current year, any developments,
redevelopments, expansions or acquisitions are expected to be funded with bank
borrowings from the Company's credit line, construction financing, proceeds from
the operation of the Company's dividend reinvestment plan or other external
capital resources available to the Company.

      The Company expects to fulfill its long range requirements for capital
resources in a variety of ways, including undistributed cash flow from
operations, secured or unsecured bank and institutional borrowings, private or
public offerings of debt or equity securities and proceeds from the sales of
properties. Borrowings may be at the Saul Centers, Operating Partnership or
Subsidiary Partnership level, and securities offerings may include (subject to
certain limitations) the issuance of additional limited partnership interests in
the Operating Partnership which can be converted into shares of Saul Centers
common stock.

      Management believes that the Company's current capital resources, which
includes the Company's credit line of which $40,500,000 was available for
borrowing as of March 31, 1999, will be sufficient to meet its liquidity needs
for the foreseeable future.

Financial Information

      For the first quarter of 1999, the Company reported Funds From Operations
("FFO") of $7,938,000. This represents an 7.4% increase over the comparable 1998
period's FFO of $7,388,000. FFO is presented on a fully converted basis and as
the most widely accepted measure of operating performance for REITs is defined
as net income before extraordinary and nonrecurring items and before real estate
depreciation and amortization. The following table represents a reconciliation
from net income before minority interests to FFO:

</TABLE>

      (1)   Retroactive to January 1, 1998, the Company began recognition of
            percentage rental income in accordance with a new accounting
            pronouncement. The 1998 first quarter FFO amounts previously
            reported have been increased $185,000 to provide comparability.

      FFO, as defined by the National Association of Real Estate Investment
Trusts, is calculated as net income excluding gains or losses from debt
restructuring and sales of property, plus depreciation and amortization, and
after adjustments for unconsolidated partnerships and joint ventures. FFO does
not represent cash generated from operating activities in accordance with
generally accepted accounting principles and is not necessarily indicative of
cash available to fund cash needs, which is disclosed in the Consolidated
Statements of Cash Flows for the applicable periods. There are no material legal
or functional restrictions on the use of FFO. FFO should not be considered as an
alternative to net income, as an indicator of the Company's operating
performance, or as an alternative to cash flows as a measure of liquidity.
Management considers FFO a supplemental measure of operating performance and
along with cash flow from operating activities, financing activities and
investing activities, it provides investors with an indication of the ability of
the Company to incur and service debt, to make capital expenditures and to fund
other cash needs. FFO may not be comparable to similarly titled measures
employed by other REITs.

Investing activities...................................       -6,823     -2,206

Financing activities...................................       -2,362     -3,784

Capital Strategy and Financing Activity

      The Company's capital strategy is to maintain a ratio of total debt to
total asset value of 50% or less, and to actively manage the Company's leverage
and debt expense on an ongoing basis in order to maintain prudent coverage of
fixed charges. Management believes that current total debt remains less than 50%
of total asset value.

      In January 1999, the Company closed a $38 million construction loan, which
is anticipated to fully fund the development costs associated with the 230,000
square foot North Wasington Street mixed-use office/retail complex, which the
Company is constructing in Old Town Alexandria, Virginia. The loan has an
initial three year term with an interest rate of LIBOR plus 1.90%, with the
spread over LIBOR declining as leasing of the office and retail space proceeds.
As of April 30, 1999, outstanding borrowings on this construction loan totaled
$1.8 million.

      As of April 30, 1999, outstanding borrowings on the Company's $60 million
unsecured credit line totaled $21.5 million, leaving $38.5 million of credit
availability. The Company has fixed interest rates on approximately 92% of its
total debt outstanding, which now has a weighted remaining term of approximately
12 years.

Redevelopment, Renovations and Acquisitions

      The Company has been selectively involved in redevelopment, renovation and
acquisition activities. It continues to evaluate land parcels for retail and
office development and potential acquisitions of operating properties for
opportunities to enhance operating income and cash flow growth. The Company also
continues to take advantage of redevelopment, renovation and expansion
opportunities within the portfolio, as demonstrated by its activities at French
Market, Beacon Center, Shops at Fairfax, Avenel, and North Washington Street.

      The Company has completed construction on a facade renovation and is
retenanting a 103,000 square foot anchor space at the 213,000 square foot French
Market center in Oklahoma City, Oklahoma. Leasing and occupancy of the first
three new spaces, a 41,000 square foot Bed, Bath and Beyond, an 8,000 square
foot Lakeshore Learning, a children's educational toy store and an 8,000 square
foot BridesMart formal wear retailer were completed in 1998. During the first
quarter of 1999, the Company signed a lease with a 25,000 square foot Staples
office supply store, which leaves only 21,000 square feet remaining to lease.
Staples is scheduled to open in late summer of 1999.

      The Company is redeveloping the Beacon Center, located along Route 1 in
Alexandria, Virginia. Beacon Center's central enclosed mall area was demolished
and construction has commenced on a 148,000 square foot Lowe's home improvement
and garden center store, which is scheduled to open in the summer of 1999. The
center's other tenants include anchors Giant Food, Marshalls and Office Depot,
with a complement of small shop space and restaurants. The 356,000 square feet
Beacon Center is now 100% leased. In addition to the new home improvement store,
8,000 square feet of new small shop space adjacent to Lowe's and Giant was
constructed in late 1998 and is fully occupied.

      The Company commenced another significant redevelopment during 1998 when
it signed a lease with SuperFresh for a new 53,000 square foot grocery store at
the Shops at Fairfax, located in Fairfax, Virginia. A portion of the shopping
center which includes a small enclosed mall was demolished to allow SuperFresh
to occupy a new building, with construction projected to be completed in the
fall of 1999. An additional 7,500 square feet of shop space is being constructed
adjacent to the supermarket. The facade of the adjacent Boulevard shopping
center, also owned by the Company, is being renovated and modernized. This
renovation was driven by a new 12,000 square foot lease with Party City,
scheduled to open during May 1999, which replaced a previous lease with below
market rents. Redevelopment plans also include new landscaping and a more
efficient parking scheme, which should enhance the property as a desirable
neighborhood shopping center.

      Office development and acquisition activities will be an integral part of
the Company's focus during 1999. In July 1998, the Company began development of
approximately 27,000 square feet of additional office / flex space at Avenel
Business Park on excess land that it owns. Construction of this new project
(Avenel V) was substantially completed during January 1999. Approximately 46% of
the space is leased, while leases are in negotiation for a portion of the
remaining space. Including this new development, Avenel Business Park is
currently over 95% leased.

      In February 1999, the Company announced the development of a new 230,000
square foot Class A mixed-use office / retail complex along North Washington
Street in historic Old Town Alexandria in Northern Virginia. The project is well
located on a two-acre site along Alexandria's main street. Demolition of the
Company's existing 41,500 square foot building, formerly leased to Mastercraft
furniture, was completed in March 1999. Site

                                       19

excavation is currently in progress. Construction is scheduled to be completed
by the summer of 2000. Two twin four-story buildings will feature a brick and
cast stone exterior facade with a glass curtain wall overlooking a spacious
courtyard. Amenities will include 3-story atrium lobbies, a fitness center,
concierge service, a 600 space parking structure and the latest computerized
energy management system. The street level will have 45,000 square feet of
retail space. Office space totals approximately 185,000 square feet, with the
top floor containing walkout terraces.

Portfolio Leasing Status

      At March 31, 1999, the portfolio consisted of twenty-nine Shopping
Centers, four Office Properties and one Industrial Property, all of which are
located in seven states and the District of Columbia. The Office Properties
consist of one office property and one office/retail property, both located in
the District of Columbia, and one research park located in a Maryland suburb of
Washington, D.C.

      At March 31, 1999, 91.5 % of the Company's 5.9 million square feet of
leasable space was leased to tenants, as compared to 89.2 % at March 31, 1998.
The shopping center portfolio was 94.5 % leased at March 31, 1999 versus 91.8 %
as of March 31, 1998. The Office Properties were 95.6 % leased at March 31, 1999
compared to 94.0 % as of March 31, 1998. The overall improvement in the 1999
leasing was primarily caused by the Company's successful leasing at recently
renovated shopping centers: Seven Corners, Great Eastern and Beacon Center as
well as improved leasing at the Van Ness Square office property.

Results of Operations

      The following discussion compares the results of the Company for the three
month periods ended March 31, 1999 and 1998, respectively. This information
should be read in conjunction with the accompanying consolidated financial
statements and the notes related thereto. These financial statements include all
adjustments (consisting solely of normal recurring adjustments) which are, in
the opinion of management, necessary for a fair presentation of the interim
periods presented.

Three Months Ended March 31, 1999 Compared to Three Months Ended March 31, 1998

      Revenues for the three month period ended March 31, 1999 (the "1999
Quarter"), totaled $17,964,000 compared to $17,143,000 for the comparable
quarter in 1998 (the "1998 Quarter"). Had the Company retroactively applied the
change in accounting method required by EITF 98-9, total revenues for the 1998
Quarter would have been $17,328,000. The 1999 Quarter's increase on this
comparable basis was $636,000 (3.7%).

      Base rent was $14,333,000 for the 1999 Quarter, compared to $13,471,000
for the 1998 Quarter, representing an increase of $862,000 (6.4%). The increase
in base rent resulted primarily from new leases at Seven Corners, Ravenwood and
Avenel IV (which was acquired in April 1998) for the 1999 Quarter that were not
present during the 1998 Quarter.

      Expense recoveries were $2,448,000 for the 1999 Quarter compared to
$2,320,000 for the comparable 1998 Quarter, representing an increase of $128,000
(5.5%). Recovery income increased primarily as a result of new leases in place
during 1999 at Seven Corners, Beacon Center, Southside and Avenel IV.

      Percentage rent was $780,000 in the 1999 Quarter, compared to $799,000 in
the 1998 Quarter. Had the Company retroactively applied the change in accounting
method required by EITF 98-9, percentage rent for the 1998 Quarter would have
been $984,000. The 1999 Quarter's decrease would have been $204,000 (20.7%). The
decrease in percentage rent resulted primarily from the rollover of a Ravenwood
anchor lease into higher paying base rent in lieu of percentage rent.

      Other income, which primarily consists of parking income, kiosk and
temporary leasing, and fees associated with early termination of leases, was
$403,000 in the 1999 Quarter, compared to $553,000 in the 1998 Quarter,
representing a decrease of $150,000 (27.1%). The decrease in other income
resulted primarily from a lease termination payment collected at Avenel
Business Park during the 1998 Quarter.

      Operating expenses, consisting primarily of repairs and maintenance,
utilities, payroll, insurance and other property related expenses, decreased
$35,000 (1.8%) to $1,936,000 in the 1999 Quarter from $1,971,000 in the 1998
Quarter. The expense decrease resulted in part from reduced property payroll
expense due to the elimination of maintenance positions associated with former
shopping mall space converted into strip shopping area and reduced legal
expenses connected with collections of tenant receivables.


                                       21

      The provision for credit losses increased $21,000 (52.5%) to $61,000 in
the 1999 Quarter from $40,000 in the 1998 Quarter.

      Real estate taxes increased $112,000 (7.9%) to $1,534,000 in the 1999
Quarter from $1,422,000 in the 1998 Quarter. The increase resulted from higher
taxes imposed primarily upon Seven Corners and to a lesser extent several of the
Company's other Virginia properties.

      Interest expense of $5,530,000 for the 1999 Quarter represented a decrease
of $74,000 (1.3 %) from $5,604,000 reported for the 1998 Quarter.

      Amortization of deferred debt expense increased $2,000 (2.0%) to $103,000
in the 1999 Quarter from $101,000 in the 1998 Quarter.

      Depreciation and amortization expense increased $172,000 (6.3%) from
$2,725,000 in the 1998 Quarter to $2,897,000 in the 1999 Quarter, primarily as a
result of depreciation attributable to recently completed redevelopments and
renovations.

      General and administrative expense, which consists of payroll,
administrative and other overhead expense, was $862,000 for the 1999 Quarter, an
increase of $60,000 (7.5%) over the 1998 Quarter. The increase in 1999 expenses
compared to 1998 resulted from increases in payroll and state income tax
expenses.

Year 2000 Issue

      The year 2000 issue relates to whether computer systems will properly
recognize date sensitive information to allow accurate processing of
transactions and data relating to the year 2000 and beyond. In addition, the
year 2000 issue relates to whether non-Information Technology (IT) systems that
depend upon embedded electronic technology will recognize the year 2000. Systems
that do not properly recognize such information could generate erroneous
information or fail.

      In 1995, the Company contracted to replace virtually all of its management
information and accounting systems and install a local area network (LAN). One
of the selection criteria of the new software and hardware was that they be
fully year 2000 compliant. The new LAN and management and accounting information
systems have been installed . Therefore, the Company's management information
and accounting systems are fully year 2000 compliant. As a result of its
efforts, the Company does not expect to incur any additional expense for its
information systems related to the year 2000 issue.


                                       22
<PAGE>
 
      The Company's property management staff has conducted a comprehensive
review of its non-IT systems at its shopping centers and office buildings to
determine whether any computer hardware and software in mechanical systems (i.e.
escalators, elevators, security, heating, ventilating and air conditioning
systems, etc.) are not year 2000 compliant. Work has commenced on repairs and
replacements required to make the Company's non-IT systems year 2000 compliant.
Management has determined that the costs will be less than $100,000 and will be
completed prior to July 1999.

      The Company believes there is risk that its operations may be affected by
vendors and tenants who are unable to perform as contracted due to their own
year 2000 exposure. It is very difficult to identify "the most reasonably likely
worst case scenario" at this time. The Company's potential exposure is wide
spread; however there is no known or expected major direct exposure. The Company
believes that the most likely worst case exposure is at this indirect level
where vendors and tenants fail to perform their obligations to the Company. For
example, the Company believes it is possible that certain tenants' information
systems may fail, which may delay the payment of rents. To help minimize this
risk, the Company sent a letter to each tenant prior to January 1, 1999 advising
the tenant that rent payments due January 1, 2000 must be paid on-time. These
reminders will be sent twice again later in 1999. The Company's leases contain
provisions empowering it to take certain actions to enforce it's right to the
timely payment of rent, regardless of the tenant's year 2000 exposure. While it
is not possible at this time to determine the likely impact of these potential
problems, the Company will continue to evaluate these areas and develop
contingency plans, as appropriate.

rate with respect to each Fixed Increment may be made only (i) once during any
thirty (30) day period and (ii) while no Event of Default or Unmatured Event of
Default is in existence hereunder or under any of the other Loan Documents.
Maker, at its option and upon satisfaction of the conditions set forth herein,
may request a Fixed Increment Rate to be used in calculating interest on the
portion of the unpaid principal balance and for the period selected in
accordance with and subject to the following conditions:

              (i)   One Business Day before requesting a Fixed Increment Rate,
Maker shall give Payee advance telephonic notice that it will request a rate
quotation for a portion of the principal balance of this Note and for a period
of time which conforms to a Fixed Increment and Fixed Period as defined herein.

              (ii)  At approximately 9:00 A.M. (Pacific time) on the Business
Day next following said advance notice, Maker may telephonically request Payee
to quote telephonically an applicable Fixed Increment Rate for the Fixed
Increment and Fixed Period selected by Maker. At any one time during the term
hereof, no more than five (5) Fixed Increments may be outstanding. Maker shall
not be released from its obligation to pay interest at the Applicable Rate and
Payee shall incur no liability to Maker if Maker is unable to obtain a
telephonic quote on any Business Day.

              (iii) If Maker accepts Payee's telephonic quote of the Fixed
Increment Rate requested within five (5) minutes of the quotation thereof by
Payee, interest at said Fixed Increment Rate shall accrue on the Fixed Increment
and for the Fixed Period selected. The date the quoted Fixed Increment Rate is
telephonically accepted by Maker shall be the Fixed Period Commencement Date for
that Fixed Period.

              Payee is authorized to rely upon the telephonic request and
acceptance of Scott V. Schneider and William Anhut as Maker's duly authorized
agents, or such additional authorized agents as Maker shall designate in writing
to Payee. Maker's telephonic notices, requests and acceptances shall be directed
to such officers of Payee as Payee may from time to time designate.

              If Maker elects the Fixed Increment Rate, but the applicable Fixed
Period will commence on a date which is not a Business Day, such Fixed Period
shall be deemed to commence on the next Business Day after it would otherwise
commence, and any interest which accrues hereunder in the interim shall accrue
at the Applicable Rate.

          (e) Fixed Rate Notice.  Maker's acceptance of a Fixed Increment Rate

Maker. Payee's failure to deliver the Fixed Rate Notice shall not release Maker
from Maker's obligation to pay interest at the Applicable Rate pursuant to the
terms hereof.

              ------------------------                                     
herein to the contrary, if Maker elects the Fixed Increment Rate to apply but
Payee is unable for any reason to obtain funds in the amount of the Fixed
Increment elected for the Fixed Period elected, interest on such Fixed Increment
shall accrue at the Applicable Rate unless and until a new election of the Fixed
Increment Rate is made by Maker and Payee is then able to obtain such funds.

          (g) No Effective Election.  In the absence of an effective election by
              ---------------------                                             
Maker of the Fixed Increment Rate in accordance with the above procedures prior

Increment, interest on such Fixed Increment shall accrue at the Applicable Rate,

              -------------------------

accountants', engineers', architects' and inspectors' fees and title insurance
premiums.  Except to the extent that certain of these costs and expenses are
included within the definition of Indebtedness (as defined in the Deed of
Trust), the costs and expenses shall not be credited, in any way or to any
extent, against any portion of the Indebtedness.

     3.   Special Provisions Applicable to Fixed LIBO Rate.  Notwithstanding any

<PAGE>
 
and losses resulting from the occurrence of any of the events referred to in
subsections (b) and (c) below which increase the cost to Payee of maintaining
the Loan on a Fixed LIBO Rate basis. Accordingly, Maker shall pay to Payee
within twenty (20) days of written demand, in addition to all other amounts due
under this Note and under the Loan Documents, all amounts reasonably determined
by Payee required to compensate Payee for all such costs, expenses and losses,
if any, to the extent that such costs, expenses and losses increase the cost to
Payee of maintaining the Loan on a Fixed LIBO Rate basis, provided that Payee
agrees, as soon as reasonably possible, to give Maker notice of any such
increased costs, expenses, or losses, which written notice shall include an
explanatory certificate in reasonable detail as to the increased costs.

          (b) Change in Law.  If any change in applicable law or regulations or

instrumentality of either ("Governmental Authority") charged with the
administration thereof shall:

              (i)   impose, modify, or deem applicable any reserve, special
deposit or special requirements against assets held by, or deposits in or for
the account of, or loans by, or any other acquisition of funds for advances by
Payee; or

              (ii)  impose on Payee any other conditions regarding this Note; or

              (iii) subject Payee (or make it apparent that Payee is subject) to

payment due from Maker under this Note and the other Loan Documents, other than
income and franchise taxes of the United States and its political subdivisions,
or

              (iv)  change the basis of taxation of payments due from Maker to
Payee hereunder (other than by a change in the statutory rate of taxation of the
overall income of Payee);

and any of the foregoing results in an increase in the cost to Payee of
maintaining the Loan on a Fixed LIBO Rate basis, then upon demand made by Payee
to Maker, Maker shall pay to Payee, from time to time, as reasonably determined
and certified by Payee, additional amounts that shall compensate Payee for such
increased cost. Payee will notify Maker of any event that entitles Payee to such
additional amounts and will furnish Maker with an explanatory certificate in
reasonable detail as to the increased cost as a result of any such event
mentioned in this subsection. Maker shall within twenty (20) days of written
demand pay such additional amounts to Payee. All such determinations by Payee

which interest is payable under this Note the actual costs to Payee, as
determined in good faith by Payee and evidenced by an explanatory notice
delivered to Maker by Payee, of Payee's complying with any reserve, special
deposit or similar requirements (including, but not limited to, state law
requirements and, to the extent not already paid by Maker by inclusion within
the definition of LIBO Rate Reserve Requirement, Regulations K and D of the
Board of Governors of the Federal Reserve System of the United States) imposed
or deemed applicable against foreign assets held by, or deposits in or for the
account of, or loans by, or any other acquisition of funds for advances by Payee
of any Governmental Authority charged with the administration of such
requirements, to the extent that such requirements increase the cost to Payee of
maintaining the Loan on a Fixed LIBO Rate basis.

          (a) Ability to Prepay.  Maker shall have the right prior to the

Payee in connection with such prepayment, such amounts to include that sum which

the obligation of Maker to pay to Payee certain amounts in the event of the
prepayment of a Fixed Increment prior to the last day of the applicable Fixed

          (c) Acceleration.  If an Event of Default shall occur under any of the
              ------------                                                      
Loan Documents, then Payee may, at its option, without further notice or demand,
declare the unpaid principal balance and accrued and unpaid interest on this
Note, together with any other sums owing at the time of such declaration, at
once due and payable; foreclose all security deeds, deeds of trust, mortgages
and liens securing payment hereof; pursue any and all other rights, remedies,
and recourses available to Payee, or pursue any combination of the foregoing,
all remedies hereunder and under the Loan Documents being cumulative.

          (d) No Waiver.  Failure to exercise any of the foregoing options shall
              ---------                                                         
not constitute a waiver of the right to exercise the same or any other option at
any subsequent time in respect to any other event. The acceptance by Payee of
any 

                                      -11-
<PAGE>
 
payment hereunder that is less than payment in full of all amounts due and
payable at the time of such payment shall not constitute a waiver of the right
to exercise any of the foregoing options at that time or at any subsequent time
or nullify any prior exercise of any such option without the express written
consent of Payee.

          (e) Late Charges.  If any payment required under this Note (other than
              ------------                                                      
the payment of the principal hereof at the Maturity Date or upon acceleration)
is not paid within ten (10) days after it becomes due and payable, Payee of this
Note may require an additional payment of a late charge for late payment to
compensate for Payee's loss of use of funds and for the expenses of handling the
delinquent payment, in an amount not to exceed three percent (3%) of such
delinquent payment. Said late charge shall be paid in any event not later than
the due date of the next subsequent installment of principal and/or interest.
In the event the maturity of the Indebtedness hereunder is accelerated by Payee,
this paragraph shall apply only to payments overdue prior to the time of such
acceleration.  This paragraph shall not be deemed to be a waiver of Payee's
right to accelerate payment of this Note under the terms hereof.

          (f) Interest Rate After an Event of Default.  Upon the occurrence of
              ---------------------------------------                         
an Event of Default, at the option of Payee (i) all amounts hereunder then
bearing interest at a Fixed Increment Rate shall bear interest at the Applicable
Rate, and (ii) all amounts payable hereunder or under the Loan Documents shall
bear interest for the period beginning with the date of occurrence of such
default at a rate of interest per annum (the "Default Rate"), payable on the
first day of each and every month, equal to four percent (4%) above the
Applicable Rate, as it fluctuates, or four percent (4%) above the Fixed
Increment Rate to the extent that Payee does not exercise its option to change
the Fixed Increment Rate to the Applicable Rate, as set forth in subparagraph
(5)(f)(i) above, whichever is applicable, as in effect from time to time and
continuing until such Event of Default shall have been cured.

          (g) Default Rate on Outstanding Balance.  Notwithstanding any other
              -----------------------------------                            
provision of this Note to the contrary, from and after the Maturity Date of this
Note (as it may have been extended pursuant to the terms hereof), or such
earlier date as the unpaid principal owing on this Note becomes due and payable
upon acceleration or otherwise pursuant to the terms hereof, the whole of the
unpaid principal and interest owing on this Note shall thereafter bear interest
until paid in full at the Default Rate.

          (h) Legal Tender; Costs of Collection.  All amounts payable hereunder
              ---------------------------------                                
are payable in lawful money of the United States of America.  Maker agrees to
pay all costs of collection hereof when incurred, including reasonable
attorneys' fees, whether or not any legal action shall be instituted to enforce
this Note.

          (i) Security.  This Note is issued pursuant to that certain
              --------                                               
Construction Loan Agreement of even date herewith executed by Maker and Payee
and is secured, inter alia, by the Deed of Trust.  All of the agreements,
                ----- ----                                               
conditions, covenants, warranties, representations, provisions and stipulations
made by or imposed upon Maker under the Loan Documents are hereby made a part of
this Note to the same extent and with the same force and effect as if they were
fully inserted herein, and Maker covenants and agrees to keep and perform the
same, or cause them to be kept and performed, strictly in accordance with their
terms.

          (j) Joint and Several Liability.  If this Note is executed by more
              ---------------------------                                   
than one party, each such party shall be jointly and severally liable for the
obligations of Maker under this Note. If Maker is a partnership, each general
partner of Maker shall be jointly and severally liable hereunder, and each such
general partner hereby waives any requirement of law that, in the Event of a
Default hereunder or under any of the Loan Documents, Payee exhaust any assets
of Maker before proceeding against such general partner's assets.

          (k) Time of Essence.  MAKER AGREES THAT TIME IS OF THE ESSENCE IN THE
              ---------------                                                  
PERFORMANCE OF ALL OBLIGATIONS HEREUNDER.

          (l) Governing Law.  This Note shall be governed by and construed
              -------------                                               
according to the laws of the Commonwealth of Virginia.

          (m) Usury.  It is expressly stipulated and agreed to be the intent of
              -----                                                            
Maker and Payee at all times to comply with the applicable law now or hereafter
governing the interest payable on this Note or the Loan (or applicable United
States federal law to the extent that it permits Payee to contract for, charge,
take, reserve, or receive a greater amount of interest than under Virginia law).
If the applicable law is ever revised, repealed, or judicially interpreted so as
to render usurious any amount called for under this Note, or under any of the
Loan Documents, or contracted for, charged, taken, reserved or received with
respect to the Loan, or if Payee's exercise of the option herein contained to
accelerate the maturity of this Note, or if any prepayment by Maker results in
Maker's having paid any interest in excess of that permitted by applicable law,
then it is Maker's and Payee's express intent that all excess amounts
theretofore collected by Payee be credited on the principal balance of this Note
(or if the Note has been paid in full, refunded to Maker), and the provisions of
this Note and the Loan Documents immediately be deemed reformed and the amounts
thereafter collectible hereunder and thereunder reduced, without the necessity
of the execution of any new document, so as to comply with the then applicable
law, but so as to permit the recovery of the fullest amount otherwise called for
hereunder and thereunder.

          (n) Amortization.  All sums paid or agreed to be paid to Payee for the
              ------------                                                      
use, forbearance or detention of the indebtedness evidenced hereby and by the
other Loan Documents shall, to the extent permitted by applicable law, be

                                      -13-
<PAGE>
 
amortized, prorated, allocated and spread throughout the full term of such
indebtedness until payment in full so that the rate or amount of interest on
account of such indebtedness does not exceed the usury ceiling from time to time
in effect and applicable to the Loan for so long as debt is outstanding under
the Loan.

          (o) Successors and Assigns.  The term "Maker" as used in this Note
              ----------------------                                        
shall mean and have reference to, collectively, all parties and each of them
directly or indirectly obligated for the indebtedness evidenced by this Note,
whether as principal maker, endorser, or otherwise, together with all parties
who have acquired the property conveyed by the Deed of Trust or any portion or
portions thereof, together with the respective heirs, administrators, executors,
legal representatives, successors and assigns of each of the foregoing.

          (p) No Merger.  Except as may be permitted by the terms of the Deed of
              ---------                                                         
Trust, Maker shall not merge into or with any other company, firm or corporation
without the prior written consent of Payee; provided, however, if any merger
occurs, then the resulting merged company, firm or corporation shall become
liable as Maker under this Note to the same extent as Maker hereunder. Maker
warrants and represents that Maker has full power and authority to make and
execute this Note, and that this Note is fully and legally binding upon Maker.

          (q) Notices.  All notices or other communications required or
              -------

          (a) Subject to the exceptions and qualifications described below, upon
(i) Substantial Completion of the Base Building and (ii) receipt by Payee of

reasonable attorneys' fees and all other expenses incurred by Wells Fargo in

the obligation of the undersigned to pay such indebtedness in excess of the
Adjusted Amount shall be enforceable against the undersigned only to the extent
of its interest in the property encumbered by the Deed of Trust and the other
Loan Documents and any such judgment or decree shall not be subject to execution
upon or be a lien upon the assets of the undersigned other than its interest in
such property.  All proceeds of any trustee's sale or foreclosure and/or sale of
all or any of the Trust Property or other collateral covered by the Loan

to the following exceptions and qualifications:

expenses or losses incurred by Payee as a result of any of the following:

Deed of Trust or the other Loan Documents;

               (B) Failure to pay and discharge any mechanic's liens,

Trust Property is bound or, if applicable, under Borrower's articles of

                             BORROWER'S COVENANTS
                             --------------------

     Borrower hereby unconditionally covenants with Lender as follows:

          (a) 3.1 Construction of Improvements: The construction of the
                  ----------------------------
Improvements will be commenced by Borrower on or before the Construction Start
Date, will be prosecuted by Borrower with diligence and continuity to completion
and will be completed by Borrower in a good and workmanlike manner in
substantial accordance with the Plans and other provisions of this Agreement, on
or before the Completion Date (other than for completion of tenant improvements
which shall be completed within the time period provided under each applicable
Lease) and free and clear from all liens, or claims for liens, other than the
lien and security interest created by the Loan Documents (or any of them). It is
expressly understood and agreed that, except for tenant improvements for
particular tenants' spaces which are each less than 20,000 rentable square feet,
(i) construction of the Improvements shall not be commenced unless and until
Borrower has furnished the Plans to Lender and afforded Lender the opportunity
to accept them (which acceptance shall be evidenced, if at all, by the initials
of any authorized representative of Lender thereon), (ii) when the Plans have
been furnished to Lender, no changes of a material nature will be made to them
by, or be permitted to be made to them by, Borrower, Architect or any other
person or entity without the prior written approval therefor of all requisite
Governmental Authorities, prior compliance with all requisite Legal Requirements
and prior acceptance by the Lender in its reasonable discretion; provided,
however, that the Lender's prior consent shall not be required for Permitted
Changes; and (iii) in instances where Lender does accept the Plans (or any
change therein), such acceptance shall be deemed to be strictly limited to an
acknowledgment of Lender's consent to the Improvements being constructed in
accordance therewith and shall not, in any way, be deemed to imply any warranty,
representation or approval by Lender that such Improvements, if so constructed,
will be structurally sound, will comply with all Legal Requirements, will be fit
for any particular purpose or will have a market value of any particular
magnitude. The construction of all tenant improvements to be constructed
pursuant to signed Leases shall be commenced by Borrower as required under such
tenant leases, will be prosecuted by Borrower with diligence and continuity to
completion and will be completed by Borrower in a good and workmanlike manner in
substantial accordance with the Plans and other provisions of the tenant lease,
on or before the completion date provided for in the lease and free and clear
from all liens, or claims for liens, other than the lien and security interest
created by the Loan Documents (or any of them). Lender agrees that its consent
to Plans and specifications and to changes therein shall not be unreasonably
withheld, conditioned or delayed and be deemed given if not expressly withheld
by Lender in writing within ten (10) business days after request for such
consent and submission of the Plans and specifications or revised Plans and

                                       10

specifications and other requested materials relating to such Plans and
specifications.

          (a) At all reasonable times during construction of the Improvements,
Borrower will (i) permit Lender, the Independent Inspecting Architect and their
representatives to enter upon the Land and into the Improvements, to inspect the
same and all materials to be used in construction of the Improvements and to
examine the Plans, (ii) comply strictly with any and all Legal Requirements
required to be complied with incidental to such construction, (iii) deliver to
Lender, or its representatives, immediately upon demand, counterparts and/or
conditional assignments of any and all Construction Contracts, bills of sale,
statements, conveyances, receipted vouchers or agreements of any nature under
which Borrower claims title to any materials or supplies used or to be used in
the construction of the Improvements, (iv) erect and maintain on the Land, at
Borrower's sole cost and expense, in a reasonable size and location, a sign
satisfactory to Lender stating that construction financing for the Improvements
has been furnished by Lender, and stating Lender's address and phone numbers,
(v) either cause each Construction Contract having a value in excess of
$1,000,000.00 to contain a provision specifically subordinating any lien right
against the Trust Property to the liens and security interests created by the
Loan Documents or cause the other party thereto to execute any and all
instruments, acceptable in form and substance to Lender, to accomplish the same,
or to provide Lender with lien waivers or releases in accordance with the
provisions of Paragraph 6.4(b)(iv), (vi) furnish to Lender, immediately after
completion of the pouring of all concrete slabs, streets and curbstones within
the Land, and completion of the foundations of the structures forming part of
the Improvements, a survey certified to by a licensed engineer acceptable to
Lender showing all of same and that the location thereof is entirely within the
property lines of the Land and does not encroach upon, breach or violate any
building line, easement or similar restriction, (vii) use all advances made to
it by Lender for, and only for, payment of the costs itemized in Paragraph 6.2
hereof and under no circumstances use, directly or indirectly, any portion of
such advances for any other purpose, including, without limiting the generality

profit to Borrower, (viii) obtain and maintain, or cause the General Contractor
to obtain and maintain, in full force and effect, an owner's and contractor's
liability insurance policy or policies (including workers' compensation
insurance) and a hazard insurance policy or policies in builder's all risk form
with loss payable endorsements acceptable to Lender insuring the Improvements
and all material and supplies purchased with advances hereunder against all
risks and losses, all such insurance policies to be issued by companies, in
amounts and on terms approved by Lender, and (ix) upon demand of Lender or the
Independent Inspecting Architect, correct any structural defect in the
Improvements or any material departure from the Plans not accepted by Lender
(except for those Plans whose approval by Lender is not required by this
Agreement), it being understood

                                       11
<PAGE>
 
and agreed that the advance of any Loan proceeds shall not constitute a waiver
of Lender's right to require compliance with this Paragraph 3.2 with respect to
any such defects or departures.

          (b) Borrower shall use all commercially reasonable efforts to ensure
that the following are Year 2000 Compliant in a timely manner, but in no event
later than December 31, 1999: (i) the Property and Improvements; (ii) Borrower

inquiries of and request reasonable validation that each of the following are
similarly Year 2000 Compliant: (x) all major tenants or other entities from
which Borrower receives payments; and (y) all major contractors, suppliers,
service providers and vendors of Borrower. As used in this paragraph, "major"
shall mean properties or entities the failure of which to be Year 2000 Compliant
would have a material adverse economic impact upon Borrower. In furtherance of
this covenant, Borrower shall, in addition to any other necessary actions
perform a comprehensive review and assessment of all systems of Borrower, the
Property and Improvements, and, if necessary or warranted based on such review
and assessment, shall adopt a detailed plan, with itemized budget, for the
testing, remediation, and monitoring of such systems. Borrower shall, within
thirty business days of Lender's written request, provide to Lender such
certifications of or other evidence of Borrower's compliance with the terms of
this paragraph as Lender may from time to time reasonably require. Year 2000
Compliant shall mean in regard to any property or entity, that all software,
hardware, equipment, goods or systems utilized by or material to the physical
operations, business operations, or financial reporting of such property or
entity (collectively the "systems") will properly perform date sensitive
functions before, during and after the year 2000.

          (c) Borrower shall commence the construction of the Improvements on or
before the Construction Start Date.

     3.3  Negative Covenants:
          ------------------ 

          (a) At no time shall Borrower (i) use, maintain, operate or occupy, or
allow the use, maintenance, operation or occupancy of, any portion of the Trust
Property for any purpose which violates any Legal Requirement or in any manner
which may be dangerous unless safeguarded as required by law or which may
constitute a public or private nuisance or which may make void, voidable or
cancelable or increase the premium of any insurance then in force with respect
thereto unless the insurance premium shall have been paid by such user or by
Borrower, or (ii) create or place, permit to be created or placed or, through
any act or failure to act, acquiesce in the creation or placing of, or allow to
remain, any mortgage, deed of trust, security deed, lien (statutory,
constitutional or contractual), pledge, security interest, encumbrance or charge
or conditional sale or other title retention agreement on the Trust Property (or
any portion thereof) other than those created by or expressly permitted under
the Loan

                                       12
<PAGE>
 
Documents, regardless of whether same is expressly subordinate to the liens and
security interests created in the Loan Documents. If any such mortgage, deed of
trust, security deed, lien, pledge, security interest, encumbrance or charge is
asserted against the Trust Property (or any portion thereof), Borrower shall
promptly, at its own cost and expense, (a) pay the underlying claim in full or
take any other action necessary to cause same to be released of record or if
permitted by Lender, in its sole discretion, bonded to the satisfaction of
Lender and the Title Company, and (b) within five (5) days from the date
Borrower receives notice that such mortgage, lien, pledge, security interest,
encumbrance or charge has been asserted, give Lender notice thereof. The notice
shall specify who is asserting such mortgage, lien, pledge, security interest,
encumbrance or charge and shall detail the origin and nature of the underlying
claim giving rise to the asserted mortgage, lien, pledge, security interest,
encumbrance or charge.

          (b) At no time shall SCI amend or otherwise modify, in a manner which
would materially adversely affect Beneficiary, its Articles of Incorporation
without the prior written consent of Lender.

     3.4  Other Covenants:
          --------------- 

          (a) At all times, SCI shall maintain a Total Indebtedness to Gross
Asset Value ratio equal to or less than 0.65:1.0.

          (b) At all times, SCI shall maintain a minimum Adjusted EBITDA to
Fixed Charge coverage ratio equal to or greater than 1.60:1.

          (c) At no time shall SCI make or pay annual distributions or dividends
to its shareholders (other than those reinvested pursuant to a dividend
reinvestment plan), in respect of any fiscal quarter which when aggregated with
such distributions and dividends paid in respect of the preceding three (3)
fiscal quarters exceeds ninety-five percent (95%) of FFO for such four (4)
quarters.

                                       13
<PAGE>
 
          (h) SCI and Holdings shall each provide, within fifty (50) days of
each quarter end and within one hundred (100) days of each fiscal year end,
respectively, to Lender consolidated financial statements including balance

          (i) Borrower shall not enter into Leases other than those approved by
Lender or for which the approval of Lender is not required under Paragraph 10.4
of the Deed of Trust.

     3.5  Completion Deposit: If, in the good faith judgment of the Lender, it
          ------------------                                                  
appears at any time or from time to time that the unadvanced Loan proceeds will
be insufficient to (a) pay all costs to be incurred in connection with the
completion of the development of the Trust Property and the construction,
marketing, ownership, management, maintenance, operation and sale or leasing of
the Improvements in accordance with the Plans and with this Agreement, (b) pay
all sums which may accrue under the Loan Documents prior to completion of
construction, including, without limiting the generality of the foregoing,
interest on the Indebtedness, and (c) enable Borrower to perform and satisfy all

within ten (10) days of written demand by Lender deposit, or shall make
arrangements satisfactory to Lender for the deposit, with Lender, of the

interest bearing account, need not be segregated from any of Lender's other
funds and may be disbursed in accordance with the provisions of the Loan
Documents by Lender before Lender makes any further advances on the Note.
Borrower's failure to deposit the Completion Deposit with Lender shall
constitute an Event of Default hereunder.  Calculation of the Completion Deposit
shall not include the land cost or the value of the Land free and clear of
encumbrances as described in Paragraph 3.6 of this Agreement.

     3.6  Borrower's Contributions:  The Borrower shall provide to the Lender
          ------------------------                                           
prior to the first draw evidence satisfactory to Lender that the Trust Property
is free and clear of all liens and encumbrances, except as otherwise provided in
the Loan Documents.  Until the occurrence of an Event of Default, and thereafter
at the option of Lender, the Borrower shall perform the development management
services for the construction and development of the Improvements without
charge.

                                   ARTICLE 4

                                  INSPECTION
                                  ----------

     4.1  Right of Inspection:  Lender, through its officers, agents or
          -------------------                                          
employees, shall have the right at all reasonable times at Borrower's expense:

                                       14
<PAGE>
 
          (a) To enter upon the Trust Property and inspect the construction to
determine that it is in conformity with the Plans and all the requirements
hereof; and

          (b) To examine, copy and make extracts of the books, records,
accounting data and other documents of Borrower that relate in any way to the
Trust Property, including, without limiting the generality of the foregoing, all
permits, licenses, consents and approvals of all Governmental Authorities having
jurisdiction over Borrower or the Trust Property and, to the extent the Borrower
has the power to do so or can provide assistance, all relevant books and records
of contractors and subcontractors supplying goods and/or services in connection
with the construction of the Improvements. All such books, records and documents
of Borrower shall be made available to Lender promptly upon written demand
therefor; and, at the request of Lender, Borrower shall furnish Lender with
convenient facilities for the foregoing purpose.

     4.2  No Duty to Inspect:  It is expressly understood and agreed that Lender
          ------------------                                                    
shall have no duty to supervise or to inspect the construction of the
Improvements or any books and records of any party or firm, and that any such
inspection shall be for the sole purposes of determining whether or not the
Obligations of Borrower under this Agreement are being properly discharged and
of preserving Lender's rights hereunder. If Lender, or the Independent
Inspecting Architect acting on behalf of Lender, should inspect the construction
of the Improvements or any books and records, Lender and the Independent
Inspecting Architect shall have no liability or obligation to Borrower or any
third party arising out of such inspection. Inspection not followed by notice of
default shall not constitute an acknowledgment or representation by Lender and
the Independent Inspecting Architect that there has been or will be compliance
with the Plans or that the construction is free from defective materials or
workmanship nor shall it constitute a waiver of Lender's right thereafter to
insist that the Improvements be constructed in accordance with the Plans.
Lender's failure to inspect the construction of the Improvements or any part
thereof or any books and records shall not constitute a waiver of any of
Lender's rights hereunder. Neither Borrower nor any third party shall be
entitled to rely upon any such inspection or review. Lender and the Independent
Inspecting Architect owe no duty of care to Borrower or any third person to
protect against, or inform Borrower or any third person of the existence of,
negligent, faulty, inadequate or defective design or construction of the
Improvements.

     4.3  Borrower's Responsibilities:  Borrower shall be solely responsible for
          ---------------------------                                           
all aspects of Borrower's business and conduct in connection with the Trust
Property and Improvements, including, without limiting the generality of the
foregoing:

          (a) the quality and suitability of the Plans;

          (b) supervision of construction of the Improvements;

                                       15
<PAGE>
 
          (c) the qualifications, financial condition and performance of all
architects, engineers, contractors, subcontractors and material suppliers,
consultants, and property managers;

          (d) conformance of construction of the Improvements to the Plans, to
the Legal Requirements and to the requirements of this Agreement;

          (e) the quality and suitability of all materials and workmanship;
and

          (f) the accuracy of all requests for the disbursement of Loan proceeds
and the proper application of disbursed Loan proceeds.

     4.4  Inspection Fee:  In furtherance of Lender's rights hereunder, Lender
          --------------                                                      
may, at its option, (a) require an inspection of the Trust Property by the
Independent Inspecting Architect (i) prior to each advance; (ii) at least once
each month during the course of construction even though no advance is to be
made for that month; (iii) upon Completion of the Improvements, and (iv) at
least semi-annually thereafter; and (b) require costing and a review of the
Plans for the Base Building and for tenant spaces of 20,000 rentable square feet
or more by the Independent Supervising Architect and/or a cost engineering
specialist, or any other party contracted by Lender resulting from a review or
reviews of the initial Plans and all revisions thereof as submitted from time to
time by Borrower.  Borrower shall pay all fees incurred by Lender in connection
with this Paragraph 4.4.  Furthermore, if Lender determines in connection with
any such costing, review or inspection that extra services will be required of
the Independent Inspecting Architect as a result of noncompliance with the
Plans, or with any Legal Requirement or as a result of deviations from
acceptable construction practices, or as a result of Borrower's failure to
satisfy the requirements of or any other Agreement, the Borrower shall pay, in
addition to the fees for such costing, review of the Plans and inspections, the
cost of all such extra services.

                                   ARTICLE 5

                              ADDITIONAL SECURITY

Construction Contract furnished to Lender is a true and complete copy thereof
and that Borrower's interest therein is not subject to any claim, setoff or
encumbrance.

any assumption by Lender of any obligations under the Construction

                                       16
<PAGE>
 
Contracts; and Borrower shall continue to be liable for all obligations of
Borrower thereunder, Borrower hereby agreeing to perform all of its obligations
under the Construction Contracts. Borrower agrees to indemnify and hold Lender
harmless against and from any loss, cost, liability or expense (including, but
not limited to, reasonable attorneys' fees) incurred by Lender and resulting
from any failure of Borrower to so perform.


          (c) At any time there shall be an uncured Event of Default, or even in
the absence of an Event of Default at any time that Lender shall believe in good
faith that the General Contractor may cease work on the construction of the
Improvements, but in any event with simultaneous notice to Borrower, Lender
shall have the right at any time (but shall have no obligation) to take, in its
name or in the name of Borrower, such action as Lender may at any time determine
to be necessary or advisable to cure any default under the Construction
Contracts or to protect the rights of Borrower or Lender thereunder. Lender
shall incur no liability if any action so taken by it or in its behalf shall
prove to be inadequate or invalid, and Borrower agrees to hold Lender free and
harmless from any loss, cost, liability or expense (including, but not limited
to, reasonable attorneys' fees) now or hereafter incurred by Lender in
connection with such action.

          (d) Borrower hereby irrevocably constitutes and appoints Lender as
Borrower's attorney-in-fact, in Borrower's name or in Lender's name, to enforce
all rights of Borrower under the Construction Contracts; provided, however,
Lender shall have no obligation to enforce such rights.

          (e) Prior to an Event of Default, Borrower shall have the right to
exercise its rights as owner under the Construction Contracts; provided,
however, Borrower shall not cancel or amend the Construction Contracts in any
material respect or do, omit to do, or suffer to be done any act which would
impair the security constituted by this Agreement without the prior written
consent of Lender.

          (f) This assignment shall inure to the benefit of Lender, its
successors and assigns, including any purchaser upon foreclosure of the Trust
Property or any grantee under a deed in lieu of foreclosure, any receiver in
possession of the Trust Property and any corporation formed by or on behalf of
Lender which assumes Lender's rights and obligations under this Agreement.

     5.2  Plans: As additional security for the payment of the Indebtedness,
          -----
Borrower hereby transfers and assigns to Lender all of Borrower's right, title
and interest in and to the Plans, and agrees that when the Plans are delivered
to Lender for approval or otherwise such delivery, unless otherwise set forth in
writing accompanying such delivery, such delivery will constitute a
representation and warranty by Borrower that:

          (a) The original counterparts of the Plans furnished to Lender are
true and complete;

                                       17

          (b) The schedule of the Plans delivered to Lender is a complete and
accurate description of the Plans; and

          (c) The Plans are complete and adequate for the construction of the
Improvements and there have been no modifications thereof except as described in
such schedule. The Plans (other than those for tenant improvements for tenant
space of less than 20,000 square feet) shall not be modified without the prior
written consent of Lender except for Permitted Changes.

     5.3  Borrower agrees that:

          (a) Lender may use the Plans for any purpose relating to the
Improvements, including, but not limited to, inspections of construction and the
Completion of the Improvements;

          (b) Lender's acceptance of the assignment contained in Paragraph 5.2
shall not constitute approval of the Plans by Lender;

with the Plans and no responsibility for the adequacy thereof or for the
construction of the Improvements contemplated by the Plans; and

          (d) Such assignment shall inure to the benefit of Lender, its
successors and assigns, including any purchaser upon foreclosure of the Trust
Property, any grantee under a deed in lieu of foreclosure, any receiver in
possession of the Trust Property and any corporation formed by or on behalf of
Lender which assumes Lender's rights and obligations under this Agreement.

     5.4   Permits:  As additional security for the payment of the Indebtedness,
           -------

and that Borrower's interest therein is not subject to any claim, setoff or
encumbrance.

hereby agreeing to perform all of its obligations under the Permits. Borrower
agrees to indemnify and hold Lender harmless against and from any loss) cost,
liability or expense (including, but not limited to, reasonable attorneys' fees)
incurred by Lender and resulting from any failure of Borrower to so perform.

          (c) At any time there shall be an uncured Event of Default, or even in
the absence of an Event of Default at any time that Lender shall believe in good

                                       18
<PAGE>
 
faith that a Permit may be terminated or may expire, but in any event with
simultaneous notice to Borrower, Lender shall have the right at any time (but
shall have no obligation) to take, in its name or in the name of Borrower, such
action as Lender may at any time determine to be necessary or advisable to cure
any default under the Permits, or to protect the rights of Borrower or Lender

     6.1    Loan: Subject to the terms, provisions and conditions of this
            ----
Agreement, Lender will make and Borrower will accept, in installments, a loan in
the aggregate amount of the principal sum of the Note, it being understood that
interest as called for in the Note shall be calculated only on any sums actually
advanced and only from the dates of such advances.

     6.2    Right to Disbursements: Advances shall be made to Borrower or any of
            ----------------------
them on the principal amount of the Note at the times and otherwise in
accordance with the Disbursement Schedule attached hereto as Exhibit B and
                                                             ---------

disbursed, at Lender's option, (i) by Lender's check drawn upon Lender's
disbursement account and delivered to Borrower, (ii) by depositing the amount of

                                       19
<PAGE>
 
the Improvements or the Loan evidenced by the Note. Notwithstanding anything set
forth in the Disbursement Schedule, the advance as to which Borrower shall be
entitled at any one time shall not exceed the cost of the materials, supplies
and equipment purchased for and incorporated into the Improvements or stored on
the Land in a manner acceptable to Lender. Under no circumstances shall any
portion of any advance be used for any purpose other than the payment of those
costs and fees approved by Lender as legitimately relating to the purchase price
for the Land, the cost of constructing the Improvements and the payment of the
Indebtedness. Any sums drawn under any letters of credit which may be issued by
Lender or an affiliate of Lender on behalf of Borrower in connection with the
Loan shall be deemed advances for purposes hereof, effective as of the date the
letter of credit is issued, and shall be secured by the Deed of Trust and the
other Loan Documents.

Except as may be provided otherwise in the Disbursement Schedule, for each
advance made to Borrower hereunder to the extent to be used to fund hard costs
under the Construction Contract, Lender shall retain a sum equal to five percent
(5%) thereof (or a greater percentage, if required by any Legal Requirement) so
that until a period of thirty (30) days after Substantial Completion of the Base
Building (or such longer period if permitted or required by any Legal
Requirement or if, during such longer period, a lien or claim could lawfully be
filed against the Trust Property by anyone performing work or services, or
furnishing materials or goods in connection with the Improvements) Lender shall
have in its possession a fund equal to five percent (5%) of the total cost of
the Base Building under the Construction Contract; provided, however subject to
the provisions of Paragraph 3.6 hereof and so long as Lender maintains minimum
retainage as set forth above, Lender shall advance the excess retainage held
with respect to individual contractors performing work or services, or
furnishing materials or goods in connection with the Improvements at the earlier
of (i) Lender's receipt of such contractor's final waiver of liens or (ii) the
expiration of any statutory time Period within which such contractor could
lawfully file a lien or claim against the Trust Property.

Building payment of the Indebtedness or performance of the Obligations is
threatened by reason of a material adverse change in the financial condition or
credit standing of Borrower.

                ---------------------------------                             
fail or refuse to keep in full force and effect any permit, license, consent or

          8.1   Rights, Remedies and Recourses: Upon the happening of any Event

hereinafter provided) or demand, which is hereby expressly waived.

                         GENERAL TERMS AND PROVISIONS
                         ----------------------------

     9.1  Performance at Borrower's Expense: Without in any way limiting
          ---------------------------------                             
Paragraph 8.1 hereof, Borrower shall pay to Lender immediately upon demand all
costs and expenses incurred by Lender in connection with: (a) the preparation of
this Agreement and any and all other Loan Documents contemplated hereby
(including any amendments hereto or thereto or consents, releases or waivers
hereunder or thereunder); (b) the administration of this Agreement and the other
Loan Documents for the term of the Note as provided for in the Loan Documents;
and (c)  the enforcement or satisfaction by Lender of any of Borrower's
Obligations under this Agreement or under the Loan Documents.  For all purposes
of this Agreement, Lender's costs and expenses shall include, without
limitation, all appraisal fees incurred in connection with the making of the
Loan described in the Loan Documents or the extension of the Maturity Date as
provided for in the Note, the cost of engineering and inspection fees,
architectural fees, legal fees (including, without limitation, fees for trial,
appeal or other proceedings), accounting fees, environmental consultant fees (if
any), auditor fees, and the cost to Lender of any documentary taxes, recording
fees, brokerage fees, title insurance premiums and title surveys.  In addition,
Borrower recognizes and agrees that formal written appraisals of the Trust
Property by a licensed independent appraiser may be required by federal
regulatory reporting requirements on an annual and/or specialized basis and,
after the occurrence of an Event of Default, by Lender's internal procedures,
and Borrower shall pay such costs if Lender incurs them.  Except to the extent
that certain of these costs and expenses are included within the definition of
Indebtedness, the payment by Borrower of any of these costs and expenses shall
not be credited, in any way or to any extent, against any portion of the
Indebtedness.

<PAGE>
 
     9.2  Brokerage Fees and Commissions:  Borrower hereby indemnifies Lender
          ------------------------------                                     
from any responsibility and/or liability for the payment of any commission,
charge, or brokerage fee which may be payable to any party in connection with
the Loan, it being understood that all such charges, if any, will be paid by the
Borrower.  Lender agrees that it has not engaged any broker in connection with
this Loan.

     9.3  Time:  Time is of the essence of this Agreement and each provision
          ----                                                              
hereof of which time is an element.

     9.4  Attorneys' Fees:  If Lender finds it necessary to obtain the services
          ---------------                                                      
of an attorney to collect all or any portion of the principal of the Note or
enforce any of its rights under the Loan Documents, Borrower shall pay such
reasonable attorneys' fees (except in connection with the enforcement of its
rights under the Loan Documents), whether or not suit is brought, or if brought,
prosecuted to judgment.

     9.5  Intentionally Deleted

     9.6  Approval of Lender and Further Assurances:  Except as may be otherwise
          -----------------------------------------                             
specifically provided in the Loan Documents, all instruments of insurance to be
executed and/or delivered to Lender, and all procedures to be taken in
connection with this Agreement and the Loan provided for herein, and all persons
or parties responsible in any way for the construction of the Improvements
pursuant to any of the Construction Contracts or any obligation to be performed
hereunder, or under the other Loan Documents, shall be subject to the acceptance
of Lender as to form, substance, coverage and identity. Immediately upon request
of Lender, Borrower will execute, acknowledge and deliver to Lender such further
instruments and do such further acts as Lender may deem necessary to carry out
more effectively the purpose of this Agreement or to subject to the liens and
security interests of the Loan Documents any property intended by the terms
thereof to be covered thereby, including specifically, but without limitation,
any renewals, additions, substitutions, replacements, betterments or
appurtenances to the Trust Property.

     9.7  No Waiver:  Any failure by Lender to insist, or any election by Lender
          ---------                                                             
not to insist, upon Borrower's (or any of them) strict performance of any of the
terms, provisions or conditions of the Loan Documents shall not be deemed to be
a waiver of same or of any other term, provision or condition thereof and Lender
shall have the right at any time thereafter to insist upon strict performance by
Borrower of any and all of same. In particular, no advance by Lender of any Loan
proceeds hereunder notwithstanding Borrower's failure to strictly comply with
Article 6 hereinabove shall, in any way, preclude Lender from thereafter
declaring such failure to comply to be a default or an Event of Default
hereunder as may be provided with respect to such failure.

     9.8  Modification:  This Agreement shall not be amended, waived, discharged
          ------------                                                          
or terminated orally but only by an instrument executed by the party

                                       32
<PAGE>
 
against enforcement of the amendment, waiver, discharge or termination is
sought.

     9.9  Applicable Law:  This Agreement has been executed under, and shall be
          --------------                                                       
construed and enforced in accordance with, the laws of the Commonwealth of
Virginia from time to time in effect; except to the extent superseded by United
States federal law.  This Agreement and all of the Loan Documents are intended
to be performed in accordance with and only to the extent permitted by, all
applicable Legal Requirements, but the foregoing shall not be construed to limit
the terms of the Loan Documents by application of any provision of Borrower's
Articles of Incorporation, By-laws, or Partnership, Limited Partnership, Joint
Venture, Trust, Articles of Organization, Operating Agreement or other form of
business association agreement.  It is expressly stipulated and agreed to be the
intent of Borrower and Lender at all times to comply with the applicable law now
or hereafter governing the interest payable on the Indebtedness. If the
applicable law is ever revised, repealed or judicially interpreted so as to
render usurious any amount called for under the Note or under any of the Loan
Documents or contracted for, charged, taken, reserved or received with respect
to the Indebtedness, or if Lender's exercise of the option herein contained to
accelerate the maturity of the Indebtedness, or if any prepayment by Borrower
results in Borrower's having paid any interest in excess of that permitted by
applicable law, then it is Borrower's and Lender's express intent that all
excess amounts theretofore collected by Lender be credited to the principal
balance of the Note or any other principal indebtedness of Borrower to Lender
(or, if the Note and all of such other indebtedness have been paid or would
thereby be paid in full, refunded to Borrower), and the provisions of the Note,
the Deed of Trust, this Agreement and the other Loan Documents immediately be
deemed reformed and the amounts thereafter collectible hereunder and thereunder
reduced, without the necessity of the execution of any new documents, so as to
comply with the then applicable law, but so as to permit the recovery of the
fullest amount otherwise called for hereunder and thereunder. All sums paid or
agreed to be paid to Lender for the use, forbearance or detention of the
Indebtedness shall, to the extent permitted by applicable law, be amortized,
prorated, allocated and spread throughout the full term of such Indebtedness
until payment in full so that the rate or amount of interest on account of such
indebtedness does not exceed the usury ceiling from time to time in effect and
applicable to the Indebtedness, if any, for so long as the Indebtedness is
outstanding.

     9.10 Severability: If any provision hereof or of any of the other Loan
          -------------                                                    
Documents or the application thereof to any person or circumstance shall, for
any reasons and to any extent, be invalid or unenforceable, neither the
application of such provision to any other person or circumstance, nor the
remainder of the instrument in which such provisions is contained, shall be
affected thereby, but rather shall be enforced to the greatest extent permitted
by law.

     9.11 Rights, Remedies and Recourses Cumulative: All rights, remedies and
          -----------------------------------------                          
recourses afforded Lender by the Loan Documents or otherwise available at law or
in equity, including specifically, but without limitation, those granted by the

                                       33
<PAGE>
 
Uniform Commercial Code in effect in the Commonwealth of Virginia (a) shall be
deemed cumulative and concurrent, (b) may be pursued separately, successively or
concurrently against Borrower or anyone else obligated under any or all of the
Loan Documents, or against the Trust Property, or against any one or more of
them, at the sole discretion of Lender, (c) may be exercised as often as the
occasion therefor shall arise, it being understood by Borrower that the
exercise, failure to exercise or election to exercise any of the same shall in
no event be construed as a waiver of same or of any other right, remedy or
recourse available to Lender, and (d) are intended to be, and shall be,
nonexclusive.

     9.12 Successors and Assigns: This Agreement shall be binding upon and
          ----------------------                                          
inure to the benefit of the parties hereto and their respective heirs,
successors, legal representatives and assigns; provided, however, that Borrower
may not assign, transfer or in any way hypothecate its interest in the Loan
Documents or the Trust Property (or any portion thereof) without Lender's prior
written consent.

     9.13 Notices: All notices or other communications required or permitted to
          -------                                                              
be given pursuant to the provisions of this Agreement shall be in writing and
shall be considered as properly given if mailed by first class United States
mail, postage prepaid, registered or certified with return receipt requested, or
sent by Federal Express or other overnight delivery service, or by delivering
same in person to the intended addressee, or by prepaid telegram. Notice so
mailed shall be effective upon its receipt.  For purposes of notice, the
addresses of the parties shall be as set forth below, provided, however, that
either party shall have the right to change its address for notice hereunder to
any other location within the continental United States by the giving of fifteen
(15) business days' notice to the other party in the manner set forth
hereinabove.

     9.14 Assignments and Participations: Lender may, at any time, sell,
          ------------------------------                                
transfer, assign or grant participations in any Loan or in any Loan Documents
that Borrower or the partners or joint venturers of Borrower have entered into,
executed, or granted in favor of Lender, and Lender may forward to each
participant and prospective participant all documents and information relating
to any such Loan, whether furnished by Borrower or otherwise, as Lender
determines necessary or desirable.

     9.15 Lender's Right to Perform the Obligations: If Borrower shall fail,
          -----------------------------------------                         
refuse or neglect to make any payment or perform any act required by the Loan
Documents, then Lender at any time thereafter and in any circumstance where
Lender determines that an emergency exists with simultaneous or prompt notice
thereafter to or demand upon Borrower and in other circumstances with notice to
Borrower and Borrowers' failure to cure such failure, refusal or neglect within
thirty (30) days of such notice, and without waiving or releasing any other
right, remedy or recourse Lender may have because of same, may (but shall not be
obligated to) make such payment or perform such act for the account of and the
expense of Borrower, and shall have the right to enter the Land and Improvements
for such purpose and to take all such action thereon and with respect to the
Trust Property as it may deem necessary or appropriate and Borrower hereby
irrevocably constitutes and appoints Lender as its attorney-in-fact, which
appointment shall be deemed coupled with an interest, to take the actions
described in this paragraph. If Lender shall elect to pay any statement,
invoice, tax bill or other sums due with reference to the Trust Property, Lender
may do so in reliance on any bill, statement or assessment procured from the
appropriate Governmental Authority or other issuer thereof without inquiring
into the accuracy or validity thereof.  Similarly, in making any payments to
protect the security intended to be created by the Loan Documents, Lender shall
not be bound to inquire into the validity of any apparent or threatened adverse
title, lien, encumbrance, claim or charge before making an advance for the
purpose of preventing or removing the same. Borrower shall indemnify Lender for
all losses, expenses, damages, claims and causes of action, including reasonable
attorneys' fees, incurred or accruing by reason of any acts performed by Lender
pursuant to the provisions of this Paragraph 9.15 or pursuant to any other
provision in the Loan Documents, except those due to Lender's gross negligence
or willful misconduct. All sums paid by Lender pursuant to this Paragraph 9.15,
together with all other sums expended by Lender to which it shall be entitled to
be indemnified, together with interest thereon at the Default Rate (as defined
in the Note) from the date of such payment or expenditure, shall constitute
advances on and additions to the Indebtedness, shall be secured by the Loan

                                       35

Documents and shall be paid by Borrower to Lender upon demand.  Prior payment by
Lender shall not be a condition precedent to the obligations of Borrower under
this indemnity.

     9.16 Taxes and Assessments. Subject to Borrower's right to contest as
          ---------------------                                           
provided for under the Loan Documents, Borrower shall submit to Lender copies of
tax statements and adequate documentation evidencing the due and punctual
payment of all real estate and personal property taxes, charges and assessments
levied or imposed upon the Trust Property on or before ten (10) days of the due
date of any such taxes.

     9.17 Waiver of Right to Trial By Jury.  Each party to this Agreement
          --------------------------------                               
hereby expressly waives any right to trial by jury of any claim, demand, action
or cause of action (1) arising under this Agreement or any other instrument,
document or agreement executed or delivered in connection therewith, or (2) in
any way connected with or related or incidental to the dealings of the parties
hereto or any of them with respect to this Agreement or any other instrument,
document or agreement executed or delivered in connection herewith, or the
transactions related hereto or thereto, in each case whether now existing or
hereafter arising, and each party hereby agrees and consents that any such
claim, demand, action or cause of action shall be decided by court trial without
a jury, and that any party to this Assignment may file an original counterpart
or a copy of this paragraph with any court as written evidence of the consent of
the parties hereto to the waiver of their right to trial by jury.

Borrower to make payments to subcontractors for material or labor or (4) a
reasonable doubt that the construction can be completed with the balance of Loan
proceeds then undisbursed. When all such grounds are removed, payment shall be
made of any amount so withheld because of them.

mechanics' or materialmen's liens or pending disbursements, with no additional

calendar years unless modified or revoked in accordance with section 3.3.

section 3.1(b) to have Director's Fees credited to his or her Cash Deferred Fee
Account, the Company shall credit the Director's Cash Deferred Fee Account with

been paid to the Director if they had not been deferred under the Plan.

     (b)  When a Director elects under section 3.1(b) to have Director's Fees
credited to his or her Stock Deferred Fee Account, the Company shall credit the
Director's Stock Deferred Fee Account with a number of Shares as of the day such

                                   DIVIDENDS

     5.1 CREDITING OF DIVIDENDS. Each Director with shares credited to his or
her Stock Deferred Fee Account on the record date of a dividend on the Company's
common stock shall be credited on the payment date of the dividend with an
amount determined by the product of the number of shares credited to the
Director's Stock Deferred Fee Account on the dividend record date and the
dividend per share on the Company's common stock. Such amount shall be credited
on the dividend payment date to the Director's Cash Deferred Fee Account, unless
the Director at such lime has a Deferred Fee Agreement in effect which provides
for the deferral of any portion of the Directors fees otherwise payable during
the period which includes the dividend payment date to be credited to the
Director's Stock Defected Fee Account. In such a case, the dividend reinvestment
provisions of Section 5.2 shall apply.

     5.2 DIVIDEND REINVESTMENT SHARES. If the Director has a Deferred Fee
Agreement in effect on the payment date of dividends on the Company's common
stock and such Deferred Fee Agreement provides for any portion of the Director's
fees otherwise payable during the period which includes the dividend payment
date to be credited to the Director's Stock Deferred Fee Account, then on the
dividend payment date the Director's Stock Deferred Fee Account shall be
credited with a number of shares determined by dividing the amount of the
dividends for the Director as determined under Section 5.1 by ninety-seven
percent (97%) of Fair Market Value of the Company's common stock on the dividend
payment date.

                           PAYMENT OF DEFERRED FEES

     6.1  DEFERRED FEES AND INTEREST.  A Director shall be entitled to receive a
benefit equal to the amounts credited to his or her Deferred Fee Accounts at the
time or times specified in such Director's Deferred Fee Agreement.  Amounts
credited to a Director's Cash Deferred Fee Account shall be paid in cash. Shares
credited to a Director's Stock Deferred Fee Account shall be paid by the

Company's common shares.

     6.2 PAYMENT. (a) At the election of a Director, the amount credited to the
Director's Deterred Fee Accounts shall be paid in a lump sum or in installments
in accordance with the terms of such Director's Deferred Fee Agreement. Amounts
credited to a Director's Cash Deferred Fee Account shall bear interest at the
rate specified in Article IV during the installment payout period. Shares
credited to a Director's Stock Deferred Fee Account shall continue to result in
the crediting of additional amounts to a Director's Cash Deferred Fee Account or
additional Shares to the Director's Stock Deferred Fee Account as determined
under Article V during the installment payout period.

     (b) Notwithstanding the foregoing, no payment of shares from a Director's
Stock Deferred Fee Account shall be made unless the Company may validly issue
shares at such time pursuant to all applicable rules and regulations, including
but not limited to corporate law, securities law and stock exchange nobles.  If
Shares may not be issued, subject to compliance with applicable securities laws
requirements, the Fair Market Value of the Shares credited to a Director's Stock
Deferred Fee Account shall be distributed in cash.

practicable after the end of the calendar quarter in which the Director's death
occurred.

<PAGE>
 
Beneficiary designation shall be made either in the Deferred Fee Agreement or on
a form prescribed by the Secretary of the Company and shall be effective only
when filed with the Secretary during the Director's lifetime. Each Beneficiary
designation filed with the Secretary shall revoke all Beneficiary designations
previously made by the Director. The revocation of a Beneficiary designation
shall not require the consent of any designated Beneficiary.

                                  ARTICLE IX

                              ANNUAL STOCK AWARDS

     9.1  ANNUAL STOCK AWARDS. Each person who is a Director as of the record

termination, or the amount of Interest accrued or number of Shares to be
credited, as of such date, to his or her account.

     10.2  NO FUNDING OBLIGATION. The obligation of the Company to pay any
benefits under the Plan shall be unfunded and unsecured, and any payments under
the Plan shall be made from the general assets of the Company. The Company,
however, in its discretion, may set aside assets or purchase annuity or life
insurance contracts to discharge all or part of its obligations under the Plan.
The assets set aside or the annuity, or life insurance contracts shall remain in
