                                     PART I

ITEM 1.  BUSINESS

      Sarnia Corporation ("Sarnia" or "the Company") is the owner and operator
of commercial real estate.  Its sole asset is an office park of approximately
18.3 acres located in Springfield, Virginia known as Versar Center.  Sarnia was
incorporated in Virginia on November 22, 1982 (under the name of Versar
Virginia, Inc.) to acquire property from its then parent corporation, Versar,
Inc. ("Versar") in order to own, develop and manage the Versar Center complex.
On June 30, 1994, Versar spun-off Sarnia to Versar's shareholders on the basis
of one share of Sarnia common stock for every outstanding share of Versar
common stock.  Sarnia is now a public company traded on the over-the-counter
market.  The spin-off of Sarnia by Versar was designed to separate two distinct
businesses with different financial, investing, and operating characteristics
so that each can adopt strategies and pursue objectives appropriate to its
specific business.

      Versar Center consists of two four-story office buildings:  the 6850
Building (approximately 108,000 square feet) which was constructed in 1982, and
the 6800 Building (approximately 120,500 square feet) which was constructed in
1986.  At the end of June 1996, the 6850 Building was 93% leased and the 6800
Building was 94% leased.  On June 29, 1994, Versar and Sarnia entered into two
15-year leases through May 2009 pursuant to which Versar leased from Sarnia
108,506 square feet (99,588 of which was located in the 6850 Building).  On
June 22, 1995, Versar's lease in the 6850 Building was modified to reduce the
square footage from 99,588 to 73,371.  On July 1, 1996 Versar modified its
lease in the 6850 Building to further reduce the square footage from 73,371 to
68,239.  Three other tenants, The General Services Administration ("GSA"),
C-Cubed Corporation and RGE Engineering, lease approximately 50% of the 6800
Building and have leases which terminate between February 1997 and September
1999.

      Sarnia believes that the relatively stable employment base provided by
the federal government, supplemented by moderate business growth in the region,
makes Versar Center an attractive real estate investment.  Because of the
presence of the federal government, the area has attracted a high percentage of
professional workers which provide the region with a private sector labor force
base particularly suited to an increasingly service- oriented national economy.
The shift toward business and commercial growth and employment in the private
sector has made the regional economy more subject to recessions.

      Since 1985, the Washington, D.C. metropolitan area has had the sixth
highest employment base in the nation.  Population and employment growth in
this metropolitan area have historically moved outward from the District of
Columbia, first to the immediate suburbs, and then to the adjacent counties,
with Montgomery County in Maryland and Fairfax County in Virginia absorbing
most of the growth.  This metropolitan area has slowed its economic growth
considerably during the early 1990s due to many factors, including the lack of
affordable housing, the decrease in federal spending, the over-built office
market, poor general economic conditions and the tightening of credit standards
in the area.
 
      Fairfax County, in which Versar Center is located, has experienced
growth in the past in terms of residential, commercial and industrial
development. Growth in the County has moderated considerably since 1988
resulting in lessened demand for office space.  In the past two years, however,
the regional economy, especially in Northern Virginia and Fairfax County has
begun to expand.  That, combined with the lack of new buildings under
construction has lead to an increase in occupancy and generally higher rentals
for vacant or renewed office space.

      Versar Center competes for tenants with other properties throughout
Springfield and central Fairfax County.  Competition for tenants is on the
basis of location and rent charged.  The success of Sarnia depends on, among
other factors, the trends of the economy in the Washington, D.C. metropolitan
area, government spending and the ability of Sarnia to keep Versar Center
leased at profitable levels and controlled operating costs.

      Sarnia's staff perform the actual day-to-day management functions of
Versar Center, including maintenance of the property and equipment, tenant
build-outs and other facilities management functions.

OPERATING DATA

      The occupancy rate for the 6850 Building for fiscal years 1992 through
1996 was 93%, 94%, 93%, 99% and 93%, respectively.  The occupancy rate for the
6800 Building for fiscal years 1992 through 1996 was 60%, 79%, 85%, 93% and
94%, respectively.

      The principal businesses conducted by the tenants in the 6800 Building
and the 6850 Building are as follows:  environmental consulting, government
agencies, government contractors, an architectural firm, a health care provider
organization and other various service businesses.  Versar and National Capital
Preferred Provider Organization, Inc. ("NCPPO") are the only tenants which
occupy more than 10% of the total rentable space in the 6850 Building.
Versar's principal business is environmental engineering and consulting, and
NCPPO is a national health care provider.  C-Cubed Corporation, Cornet, GSA and
RGE Engineering each occupy more than 10% of the rentable space in the 6800
building.  The loss of any of these tenants, if not replaced, would have an
adverse effect on Sarnia's results of operations and financial condition.

      Versar entered into lease agreements with Sarnia for 68,239 square feet
of office space in the 6850 Building, and 8,918 square feet of storage space in
the 6800 Building, at an annual aggregate rent of $1,070,000.  Both leases
expire on May 31, 2009.  The lease on 6850 Building has an annual 4% escalation
with fair market adjustment every five years at June 1, 1999 and June 1, 2004.
The lease on 6800 Building is subject to 2% annual escalation.  There are no
renewal options in the leases.  Refer to Note H of the Notes to Financial
Statements.

      With respect to the 6850 Building, the average effective annual rental
per square foot was $13.59, $13.52, $13.41, $14.04 and $13.95 for fiscal years
1996, 1995, 1994, 1993 and 1992, respectively.  With respect to the 6800
Building, the average rates were $11.76, $11.52, $11.29, $11.84 and $11.95 for
fiscal years 1996, 1995, 1994, 1993 and 1992, respectively.  In addition, the
average net rental rates for both buildings were $6.09, $6.30, $5.42, $4.54 and
$6.63 for fiscal years 1996, 1995, 1994, 1993 and 1992, respectively.  The net
rental rates for Versar alone, as a significant tenant, were $6.88, $7.06,
$7.57, $8.88 and $11.25 for fiscal years 1996, 1995, 1994, 1993 and 1992,
respectively.  The average effective annual rental per square foot is derived
using annual rental income divided by occupied square feet.  The net rental 
rate represents the difference between income per square foot and operating 
expense per square foot.

ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
             RESULTS OF OPERATIONS

      Real estate revenue in 1996 of $2,771,000 was $95,000 (4%) higher than the
$2,676,000 of rental revenue reported in 1995.  The increase is attributable to
rent escalations and increased revenue from tenant requested improvements.  Real
estate revenue in 1995 of $2,676,000 was $230,000 (9%) higher than that reported
in 1994.  The increase is due to new tenants and increased tenant requested
services.

      Real estate expenses in 1996 of $1,308,000 were $100,000 (8%) higher than
the $1,208,000 of expenses reported in 1995.  The increase is due to the fact
that Sarnia received a real estate tax refund of $90,000 in fiscal year 1995
and no such refund was received in 1996.  Real estate expenses in 1995 of
$1,208,000 were $19,000 (2%) higher than those reported in 1994.  The increase
is due to the higher occupancy rate in both buildings, which resulted in an
increase in operating expenses in 1995.

      Depreciation/amortization expenses in 1996 of $619,000 were $54,000 (10%)
higher than the $565,000 reported in 1995.  The increase is due to the full
year's depreciation on the leasehold improvements that were placed in service
for the new tenants during 1995.  Depreciation/amortization expenses in 1995 of
$565,000 were $7,000 (1%) lower than the $572,000 reported in 1994.  The
decrease is due to the fully amortized assets that were placed in service in
prior years.

      General and administrative expenses in 1996 of $102,000 were $7,000 (7%)
higher than the $95,000 reported in 1995.  General and administrative expenses
in 1995 were $20,000 (27%) higher than 1994.  Increases from both years were
due to higher insurance costs.  After the spin-off from Versar, Sarnia entered
into separate insurance coverage on a stand-alone basis, which resulted in
higher insurance expenses.

      Interest expense in 1996 of $977,000 was $101,000 (9%) lower than that
reported in 1995.  Interest expense in 1995 of $1,078,000 was $76,000 (7%)
lower than the $1,154,000 in 1994.  The decreases are due to the refinancing of
debt at lower interest rates in 1996 and the increased principal payment in
1994.  Interest expense in fiscal year 1997 is expected to be lower than fiscal
year 1996, due to the refinancing of debt which took place in the middle of
fiscal year 1996, resulting in interest expense at a lower rate for six months.

      In fiscal year 1996, Sarnia recorded $34,000 preferred stock dividends of
which $7,000 was paid in April 1996 and the remaining $27,000 was paid in
September 1996.

      The net loss applicable to common stock of $269,000 in fiscal year 1996
remained relatively the same as the net loss of $270,000 in fiscal year 1995.
Higher rental revenue and lower interest expense were offset by increase in
real estate, depreciation and general and administration expenses.  The net
loss in 1995 of $270,000 was $854,000 lower than the $1,124,000 net loss
reported in 1994.  The improvement is due to the increase in rental income as
discussed above and the effect of the SFAS 109 tax adjustment recorded in 1994.

                        LIQUIDITY AND CAPITAL RESOURCES

      Cash flow provided by operating activities was $508,000, $435,000 and
$692,000 for fiscal years 1996, 1995 and 1994, respectively.  Principal
payments on the mortgages for fiscal years 1996, 1995 and 1994 were $1,323,000,
$341,000 and $889,000, respectively.  In fiscal year 1996, Sarnia issued
$750,000 of preferred stock and received a $250,000 rent deposit from Versar.
In fiscal year 1995, Versar loaned $265,000 to Sarnia, primarily for leasehold
improvements.  In fiscal year 1994, principal payments were paid through the
use of proceeds obtained from Versar of $1,273,000.  The $1,445,000 of
intercompany debt owed by Sarnia to Versar was forgiven when the spin-off
occurred on June 30, 1994.

      On January 25, 1996, Sarnia obtained a first mortgage of $9 million with
I.D.S. Life Insurance Company at the fixed rate of 7.75% to be amortized over
twenty-two years and with a balloon payment due in 2003.  Sarnia also obtained
a second mortgage of $500,000 with the Riggs National Bank at the prime rate
reported in the Wall Street Journal plus 2% (currently 10.25%) payable in 12
equal monthly installments.  On June 30, 1996, the maturity date of the second
mortgage was extended to July 1, 1997.  Sarnia also entered into a $1.5 million
term loan with the Riggs National Bank at the prime rate reported in the Wall
Street Journal plus 1% (currently 9.25%).  The term loan is amortized over
seven years payable in 66 equal monthly installments starting on the 18th month
from the date of funding.  In addition, Sarnia has issued, for $750,000, Series
A Cumulative Convertible Preferred Stock to a group of private investors.
Sarnia received a rent deposit of $250,000 from Versar and repaid a portion of
the loans it owed to Versar.

      During fiscal year 1994, Sarnia entered into an agreement with Riggs
National Bank ("Riggs") prior to the spin-off to modify two outstanding loans
from Riggs to Sarnia in the aggregate principal amount of $13,444,866, with a
principal balance of $3,031,510 being outstanding under a reducing revolving
loan, and a principal balance of $10,413,356 being outstanding under a term
loan.  Versar and certain of Versar's affiliates assumed $1,000,000 of the
outstanding principal balance of the reducing revolving loan, and Sarnia
remained primarily liable for the remaining outstanding principal balance of
$2,031,510 of the reducing revolving loan.  In fiscal year 1995, Versar paid
the $1,000,000 of outstanding principal balance of the reducing revolving loan.
The reducing revolving loan bore interest at the rate of prime plus 2.5% and
was scheduled to mature on June 1, 1997.  The term loan bore interest at the
fixed rate of 8.27% and also was scheduled to mature on May 1, 1997.  Both
loans were repaid on January 25, 1996 in connection with the refinancing
described above.

      Sarnia expects that it will require $80,000 for capital expenditures to
be made during fiscal year 1997.  It is anticipated that of such $80,000,
approximately $50,000 will be used for remodeling vacant space, and
approximately $30,000 will be used for other miscellaneous capital expenditures.
expenditures.

      While Sarnia incurred operating losses in each of the fiscal years ended
June 30, 1996, 1995 and 1994, management believes that funds generated from
rents should be sufficient to meet Sarnia's operating needs, including capital
expenditures.

               IMPACT OF ACCOUNTING STANDARDS NOT YET EFFECTIVE

      In March 1995, the Financial Accounting Standard Board issued Statement
of Financial Accounting Standards No. 121, "Accounting for the Impairment of
Long-Lived Assets and for Long-Lived Assets to be Disposed Of" ("SFAS 121").
SFAS 121 is effective for fiscal year 1997, and requires that long-lived assets
be reviewed for impairment whenever events or changes in circumstances indicate
that the carrying amount of an asset may not be recoverable.  The adoption of
SFAS 121 will not have a material effect on the financial position of the
Company.

      Statement of Financial Accounting Standard No. 123, "Accounting for
Stock-Based Compensation" ("SFAS 123") was issued in October, 1995 and is
effective for fiscal years beginning after December 15, 1995.  The Statement
encourages, but does not require, adoption of the fair value based method of
accounting for employee stock options and other stock compensation plans.  The
Company has opted to account for its stock option plan in accordance with APB
Opinion No. 25, "Accounting for Stock Issued to Employees."  By doing so, the
Company, beginning in fiscal year 1997, will be required to make proforma
disclosure of net income and earnings per share as if the fair value based
method for accounting defined in SFAS 123 had been applied.

                              IMPACT OF INFLATION

      Sarnia continually seeks to protect itself from the effects of inflation.
The majority of its leases provide for annual increases based on fixed
percentages or increases in the Consumer Price Index.

                    Report of Independent Public Accountants




To the Board of Directors and Stockholders of Sarnia Corporation:

We have audited the accompanying balance sheets of Sarnia Corporation (a
Virginia corporation) as of June 30, 1996 and 1995, and the related statements
of operations, changes in stockholders' deficit, and cash flows for each of the
three years in the period ended June 30, 1996.  These financial statements are
the responsibility of the Company's management.  Our responsibility is to
express an opinion on these financial statements based on our audits.

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

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Sarnia Corporation as of June
30, 1996 and 1995, and the results of its operations and its cash flows for
each of the three years in the period ended June 30, 1996, in conformity with
generally accepted accounting principles.

As discussed in Note G to the financial statements, effective July 1, 1993, the
Company changed its method of accounting for income taxes.

                         NOTES TO FINANCIAL STATEMENTS

NOTE A  GENERAL INFORMATION

         Sarnia Corporation (the "Company"), formerly Versar Virginia, Inc.,
was a wholly-owned real estate subsidiary of Versar, Inc. ("Versar").  The
Company was established in 1982 to own and operate the 6850 Building and the
6800 Building in Versar Center, the headquarters buildings of Versar, Inc.

         On June 30, 1994, Versar  distributed to the holders of its common
stock substantially all of the common stock of the Company (the
"Distribution").  The Distribution provided Versar stockholders one share of
Sarnia common stock for every outstanding share of Versar common stock.  The
Distribution was effected to separate two businesses with distinct financial,
investing and operating characteristics so that each can adopt strategies and
pursue objectives appropriate to its specific business.

NOTE B  SIGNIFICANT ACCOUNTING POLICIES

Basis of presentation:  These financial statements are presented using the
accrual basis of accounting.  The June 30, 1994 distribution did not affect the
carrying amount of assets and liabilities of the Company.

         Certain general and administrative functions, including general
management, treasury, financial service, legal, benefits and human resources
administration, investor and public relations and information management are
provided by Versar on a fixed fee basis.  Telephone expenses charged from
Versar based on the number of extensions used by the Company and its tenants
are included in real estate expenses.  Management believes that these charges
are made on a reasonable basis; however, they do not necessarily indicate the
costs that would have been incurred by the Company separately.

         The financial information prior to the Distribution reflects an
allocation for use of certain corporate assets and liabilities, and income tax
effects.  See discussion of income taxes in Note G.

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

Revenue recognition:  Rental revenue is recognized based upon tenant lease
agreements.  Provisions for any anticipated lease losses are made in the period
that the losses become evident.

Property and equipment:  Property and equipment are carried at historical cost
until a decline in value which is other than temporary occurs.  At such time,
the property will be reduced by a direct write-down for any impairment in value
if it is probable that the carrying amount of the property cannot be fully
recovered.

Depreciation and amortization:  Depreciation and amortization are computed on a
straight-line basis over the estimated useful lives of the assets.  Maintenance
and repair costs are expensed while improvements are capitalized.

                  NOTES TO FINANCIAL STATEMENTS (continued)


Net loss per share:  Net loss per share before cumulative effect of change in
accounting principle, net loss per share from cumulative effect of change in
accounting principle and net loss per share applicable to common stock, are
computed by dividing net loss by the number of shares outstanding during the
applicable period being reported upon.

Income taxes:  The Company accounts for certain income and expense items
differently for financial reporting purposes than for income tax reporting
purposes.  On July 1, 1993, the Company adopted Statement of Financial
Accounting Standards No. 109, "Accounting for Income Taxes" ("SFAS 109").  SFAS
109 mandates a liability method for computing deferred income taxes.
Provisions for deferred income taxes are made in recognition of temporary
differences between the book and tax bases of accounting.

Impact of Accounting Standards not yet Effective:  In March 1995, the Financial
Accounting Standard Board issued Statement of Financial Accounting Standards
No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to be Disposed Of" ("SFAS 121").  SFAS 121 is effective for fiscal year
1997, and requires that long-lived assets be reviewed for impairment whenever
events or changes in circumstances indicate that the carrying amount of an
asset may not be recoverable.  The adoption of SFAS 121 will not have a
material effect on the financial position of the Company.

         Statement of Financial Accounting Standard No. 123, "Accounting for
Stock-Based Compensation" ("SFAS 123") was issued in October, 1995 and is
effective for fiscal years beginning after December 15, 1995.  The Statement
encourages, but does not require, adoption of the fair value based method of
accounting for employee stock options and other stock compensation plans.  The
Company has opted to account for its stock option plan in accordance with APB
Opinion No. 25, "Accounting for Stock Issued to Employees." By doing so, the
Company, beginning in fiscal year 1997, will be required to make proforma
disclosure of net income and earnings per share as if the fair value based
method for accounting defined in SFAS 123 had been applied.

NOTE D  MORTGAGES

         On January 25, 1996, the Company completed the refinancing of all its
outstanding debt.

         With regard to the refinancing, Sarnia obtained a first mortgage of $9
million with I.D.S. Life Insurance Company at the fixed rate of 7.75% to be
amortized over twenty-two years and with a balloon payment due in 2003.  The
IDS mortgage is collateralized by the first deed of trust on the 6800 and 6850
buildings.  Sarnia also obtained a second mortgage of $500,000 with the Riggs
National Bank at the prime rate plus 2% payable in 12 equal monthly
installments.  On June 30, 1996, the maturity date of the second mortgage was
extended to July 1, 1997.  Sarnia also entered into a $1.5 million term loan
with the Riggs National Bank at the prime rate plus 1%.  The term loan is
amortized over seven years payable in 66 equal monthly installments starting on
the 18th month from the date of funding.  Versar guarantees Sarnia's $1.5
million term loan.  In addition, Sarnia has issued $750,000 of its Series A
Cumulative Convertible Preferred stock to a group of private investors.  Sarnia
received a rent deposit of $250,000 from Versar and repaid the majority of the
amounts it owed to Versar.

         Outstanding balances at June 30, are as follows:

         During fiscal year 1994, as part of the Distribution, Sarnia
renegotiated its reducing revolving loan (revolver) and assumed primary
responsibility from Versar for its term loan with Riggs National Bank (Riggs).
Additionally, Versar assumed $1,000,000 of the outstanding principal balance of
the revolver loan.  These loans were repaid on January 25, 1996.  See
discussion on the effect of the Distribution in Note H.

                  NOTES TO FINANCIAL STATEMENTS (continued)


         The revolver bore an interest rate of prime plus 2.5% (11.5% at June
30, 1995) and was secured by a first deed of trust on the 6850 Building.
Principal payments were scheduled over twenty five months commencing in June of
1995.  The term loan bore an interest rate of 8.27% and was secured by a first
deed of trust on the 6800 Building and a second deed of trust on the 6850
Building.  The term loan had an original payment schedule of ten years with a
thirty-year amortization.  Both loans were repaid on January 25, 1996.

         Interest payments were approximately $987,000, $979,000 and $1,192,000
for the years ended June 30, 1996, 1995 and 1994, respectively.

NOTE E STOCK OPTIONS

         During fiscal year 1995, Sarnia adopted the Sarnia 1994 Stock Option
Plan (the "Plan").  The Plan, which is compensatory in nature, provides
employees of the Company and certain other persons an incentive to remain in
the employ of the Company and encourages superior performance for the Company's
benefit.  The Company has segregated 300,000 shares of stock for inclusion in
the plan.  During fiscal year 1996, options to purchase an aggregate of 262,500
shares of common stocks with exercise prices ranging from $0.1875 to $0.375
were granted to seven directors (175,000 shares), three officers (62,500
shares) and one service provider (25,000 shares) as required by the 1994 plan
on their first anniversary of membership.

         Under the Plan, options may be granted to key employees at the fair
market value on the date of grant and vesting varies depending on the
discretion of the Compensation Committee.  Unexercised options are cancelled on
the tenth anniversary of the grant.

NOTE F PREFERRED STOCK

         At the Company's annual stockholders meeting on November 16, 1995, the
Sarnia stockholders approved an amendment to the Articles of Incorporation of
the Company authorizing the issuance of up to 1,000,000 shares of "blank-check"
preferred stock, the terms of which may be set by the Board of Directors
without further stockholder action.  Following approval of the "blank-check"
preferred stock by the stockholders, the Board of Directors adopted an
amendment to the Company's Articles of Incorporation to authorize the issuance
of 30,000 shares of Series A Cumulative Convertible Preferred Stock, and to set
the rights, privileges and preferences of such series.  All 30,000 shares of
the Series A preferred stock were issued by the Company on January 25, 1996 for
an aggregate price of $750,000.  The Series A preferred stock bears a $25 par
value and is entitled to receive preferential cumulative dividends at the
annual rate of $2.625 per share.  Also, the Series A preferred stock is
redeemable at the option of the Company and is convertible into common stock,
at the option of the holders, at a conversion price of $0.40 per share.

NOTE G INCOME TAXES

         Through fiscal year 1994, Sarnia filed consolidated income tax returns
with Versar, Inc.  Taxes calculated on a separate company basis are reflected
in the loss before extraordinary item and cumulative effect of change in
accounting principle.

         On July 1, 1993, Sarnia adopted SFAS 109, which required Sarnia to
compute deferred income taxes using the liability method.  Sarnia recognized a
charge of $440,000 in fiscal year 1994, representing the cumulative effect of
adoption of SFAS 109.  For the year ended June 30, 1994, Sarnia recorded an
additional $140,000 of deferred income taxes related to additional
tax-over-book depreciation, which resulted in an additional deferred tax
liability and an additional loss carryforward.

an increase of $109,000 for fiscal year 1996.  The change resulted from an
increase in the net operating loss carryforwards due to the taxable losses in
fiscal year 1996.

NOTE H  RELATED PARTY TRANSACTIONS

         On June 29, 1994, Versar initially rented 99,588 and 8,918 square feet
of space from Sarnia at a rate of $13.49 and $8.00 per foot, respectively.
Both spaces were subject to 2% annual rent escalators.  In June of 1995, Versar
reduced the 99,588 square feet space to 73,371 square feet and increased the
related escalation to 4%.  On July 1, 1996, National Capital Preferred Provider
Organization, Inc. ("NCPPO") occupied additional space of 5,132 square feet
which reduced Versar's space to 68,239 square feet.  The leases cover 35% of
Sarnia's total space.  Both leases are subject to adjustment on June 1, 1999
and 2004.  At these dates, the lease payments will be adjusted to the current
fair value at that time.  The adjusted lease payments are subject to the
contracted escalation in the following years.

         Sarnia and Versar maintained certain intercompany balances in fiscal
year 1994.  These intercompany balances were comprised of loans made from each
party to the other.  At the end of fiscal year 1994, Sarnia owed Versar
$1,445,000.  The $1,445,000 was forgiven when Sarnia was spun-off from Versar
in June 1994.  In fiscal year 1995, Versar loaned $265,000 to Sarnia primarily
for payments of leasehold improvements,  which was interest free.  In fiscal
year 1996, Sarnia paid Versar $83,000 leaving the loan balance at $182,000 on
June 30, 1996.

         During fiscal year 1994 in connection with the Distribution, Versar
assumed $1,000,000 of Sarnia's revolver loan and forgave Sarnia's intercompany
payable balance due to Versar.  The assumption and forgiveness of the loan and
the payable, respectively, net of related transaction costs of $305,000, were
credited directly to Sarnia's accumulated deficit during fiscal year 1994.

         The following expenses were allocated to Sarnia from Versar as
discussed in Note B:

     Noncancellable leases provide for approximate minimum rental payments
during each of the next five years as set forth below.  As to the Versar
leases, it is assumed that the payments for the second and third five-year
periods (the actual amounts of which will depend upon fair values at the
adjustment dates) will be the same as the payments for the first five years.
Certain of the other rentals may increase in future years based on changes in
the Consumer Price Index and other rental increase factors.  At July 1, 1996,
93.4% of Sarnia's space was leased.

         The name of the corporation (hereinafter, the "Corporation") is
"Sarnia Corporation."

                  II.  AMENDMENTS TO ARTICLES OF INCORPORATION

         A.      The third paragraph of Article Fifth paragraph (C) Section
2(a), Computation of Cumulative Dividends, is hereby amended to read in its
entirety as follows:

                          Such dividends on the Series A Preferred Stock shall
                 be cumulative so that if such dividends with respect to any
                 previous or current annual dividend period, at the annual rate
                 specified above, shall not have been paid or declared and a
                 sum sufficient for payment thereof set apart, the deficiency
                 shall first be fully paid before any dividend or other
                 distribution shall be paid or declared and set apart for the
                 common stock.  Payment to the holders of Series A Preferred
                 Stock for any deficiency in the payment of dividends shall be
                 applied to all accrued and unpaid dividends such that those
                 dividends most in arrears shall be paid first.  Upon any
                 conversion of the Series A Preferred Stock under Section 5
                 hereof, all such accrued and unpaid dividends to and until the
                 date of such conversion shall become due and payable and shall
                 be paid upon delivery of shares of common stock to the holder
                 of the shares of Series A Preferred Stock being converted
                 under Section 5.

         B.      Article Fifth paragraph (C) Section 5(c), Conversion Price is
hereby amended to correct the language thereof and restated in its entirety to
read as follows:

                 (c) Conversion Price.  The initial "Conversion Price" will be
                 $0.40 per share.  In order to prevent dilution of the
                 conversion rights granted under this subdivision, the
                 Conversion Price will be subject to adjustment from time to
                 time as set forth in this Section 5; provided, however, that
                 there will be no adjustment of the Conversion Price as a
                 result of (i) issuances or deemed issuances of Common Stock
                 for incentive or compensatory purposes to directors, officers
                 and employees of, and consultants to, the Corporation and its
                 subsidiaries which are from time to time approved by the Board
                 of Directors, including, without limitation, grants of stock
                 options and the issuance of common stock upon the exercise
                 thereof ("Compensatory Stock"), or (ii) issuances or deemed
                 issuances of Common Stock upon exercise or conversion, as the
                 case may be, of warrants issued in connection with any debt of
                 the corporation or the Series A Preferred Stock ("Converted
                 Stock", and together with Compensatory Stock, the "Excluded
                 Stock").  Anything herein to the contrary notwithstanding, no
                 adjustment in the Conversion Price shall be required unless
                 such adjustment, either by itself or with other adjustments
                 not





<PAGE>   2
                 previously made, would require a change of at least $0.01 in
                 such price; provided, however, that any adjustment which by
                 reason of this sentence is not required to be made shall be
                 carried forward and taken into account in any subsequent
                 adjustment.

         C.      Article Fifth paragraph (C) Section 6(d), Surrender of
Certificates, is hereby amended to clarify the terms thereof and restated in
its entirety to read as follows:

                        RESOLUTIONS TO BE ADOPTED BY THE
                    BOARD OF DIRECTORS OF SARNIA CORPORATION


         WHEREAS, on September 7, 1995, the Board of Directors of Sarnia
Corporation ("the Corporation") adopted an Amendment to the Articles of
Incorporation of the Corporation to add Paragraph (C) to Article Fifth thereof,

certain approvals by the shareholders of the Corporation, and, following
receipt of such approvals, the Board of Directors ratified such amendment to
the Articles of Incorporation on November 16, 1995;

         WHEREAS, the Board of Directors has determined that an incorrect
reference was made in Section 2(a) of Paragraph (C) in connection with the

Preferred Stock; and

         WHEREAS, to correct Section 2(a) to change the dividend payment date

comply with the intent of the Corporation that dividends would be payable
quarterly, the Board of Directors wishes to amend Paragraph (C) of Article
Fifth as set forth herein:

         NOW, THEREFORE, BE IT RESOLVED, that the first sentence of Article
Fifth, Paragraph (C), Section 2(a) be, and it is hereby, amended to read in its

         payable in arrears on the first day of March, June, September and
         December of each year.

                             ARTICLES OF AMENDMENT
                                       TO
                           ARTICLES OF INCORPORATION
                                       OF
                               SARNIA CORPORATION


                                    I.  NAME

         The name of the corporation (hereinafter, the "Corporation") is
"Sarnia Corporation".

                         II.  AMENDMENT BY SHAREHOLDERS

         A.      ARTICLE FIFTH of the Articles of Incorporation of the
Corporation shall be amended to read as follows:

         FIFTH:  (A)  The Corporation shall have the authority to issue an
         aggregate of Twenty-One Million (21,000,000) shares of capital stock,
         of which Twenty Million (20,000,000) shares shall be common stock, no
         par value per share, and One Million (1,000,000) shares shall be
         preferred stock, $25.00 par value per share.

         (B)  Shares of preferred stock may be issued from time to time in one
         or more series.  Authority is hereby vested in the Board of Directors
         of the Corporation to amend these Articles of Incorporation from time
         to time to establish series of preferred stock, to establish the
         number of shares to be included in each such series and to fix the
         preferences, limitations and relative, participating, optional,
         conversion and other special rights and qualifications, limitations or
         restrictions, of each such series.

         B.      The foregoing amendment was duly adopted by the shareholders
of the Corporation on November 16, 1995.

         C.      The foregoing amendment was proposed by the Board of Directors
of the Corporation to the Corporation's shareholders in accordance with the
provisions of the Virginia Stock Corporation Act.  On the date of the adoption
of the amendment by the shareholders of the Corporation, there were 4,572,545
shares of common stock of said Corporation outstanding and entitled to vote,
constituting the only class of stock outstanding, and the amendment to Article
Fifth to insert paragraph (A) was approved by the affirmative vote of the
holders of 4,063,960 shares, which number was sufficient for approval of this
amendment, and the amendment of Article Fifth to insert paragraph (B) was
approved by the affirmative vote of the holders of 3,115,142 shares, which
number was sufficient for approval of this amendment.

                     III.  AMENDMENT BY BOARD OF DIRECTORS

         A.      Following approval by the shareholders on November 16, 1995 of
the amendments described above, the Board of Directors of the Corporation,
acting upon the authority granted by Article Fifth (B) of the Articles of
Incorporation, as amended, adopted an amendment to the Articles of
Incorporation of the Corporation to provide for the addition of paragraph (C)
to Article Fifth to read in its entirety as follows:


<PAGE>   6
         "FIFTH: (C) 1.   Designation.  A total of 30,000 shares of the
         Corporation's preferred stock shall be designated the "Series A
         Cumulative Convertible Preferred Stock" (the "Series A Preferred
         Stock").  As used herein, the term "Preferred Stock" used without
         reference to the Series A Preferred Stock means the shares of Series A
         Preferred Stock and all other shares of Series Preferred Stock of the
         Corporation issued, authorized and designated from time to time by a
         resolution or resolutions of the Board of Directors, share for share
         alike without distinction as to class, except as otherwise expressly
         provided for in this Article Fifth or as the context otherwise
         requires.

         2.      Dividends.

                 (a)      Computation of Cumulative Dividends.  The holders of
                 the outstanding shares of Series A Preferred Stock shall be
                 entitled to receive preferential cumulative dividends
                 accruing, whether or not earned and whether or not paid, at
                 the annual rate of $2.625 per share in the case of Series A
                 Preferred Stock, payable in arrears on the first day of March,
                 June, October and December of each year.  Such dividends shall
                 accrue from day-to-day on each share of Series A Preferred
                 Stock beginning on the date of original issue, whether or not
                 earned or declared, until paid upon the schedule set forth
                 above when and as declared by the Corporation's Board of
                 Directors and to the extent permitted under the Virginia Stock
                 Corporation Act.

                          All numbers relating to calculation of cumulative
                 dividends shall be subject to equitable adjustment in the
                 event of any stock dividend, stock split, combination,
                 reorganization, recapitalization, reclassification or other
                 similar event involving a change in the capital structure of
                 the Preferred Stock to preserve the dollar amount of dividends
                 payable per initial share of Series A Preferred Stock.

                          Such dividends on the Series A Preferred Stock shall
                 be cumulative so that if such dividends with respect to any
                 previous or current annual dividend period, at the annual rate
                 specified above, shall not have been paid or declared and a
                 sum sufficient for payment thereof set apart, the deficiency
                 shall first be fully paid before any dividend or other
                 distribution shall be paid or declared and set apart for the
                 common stock.  Upon any conversion of the Series A Preferred
                 Stock under Section 5 hereof, all such accrued and unpaid
                 dividends to and until the date of such conversion shall be
                 forfeited and shall not be due and payable.

                          If at any time the Corporation pays less than the
                 total amount of dividends then accrued with respect to the
                 Series A Preferred Stock, such payment will be distributed
                 ratably among the holders of Series A Preferred Stock on the
                 basis of the amount of accrued and unpaid dividends with
                 respect to the shares of Series A Preferred Stock owned by
                 each such holder.

                 (b)      Restrictions on Distributions.  Unless all accrued
                 dividends on each share of the Series A Preferred Stock shall
                 have been paid or declared and a sum sufficient for the
                 payment thereof set apart, no dividend shall be paid or
                 declared, and no distribution shall be made, on any common
                 stock (other than a stock dividend on common stock solely in
                 the form of additional shares of common stock).  Furthermore,
                 except to the extent in any instance approval is provided by
                 the holders of a majority of the outstanding shares of Series
                 A Preferred Stock, the Corporation shall not declare or pay
                 any dividends, or purchase, redeem, retire, or otherwise
                 acquire for value any of its capital stock (or rights, options
                 or warrants to purchase such shares) now or hereafter
                 outstanding, return any capital to its stockholders as such,
                 or make any distribution of assets to its stockholders as
                 such, or permit any subsidiary to do any of the foregoing,
                 except that subsidiaries may declare and make payment of cash
                 and stock dividends, return capital and make distributions of
                 assets to the Corporation, and except that nothing herein
                 contained shall prevent the Corporation from:





<PAGE>   7
                          (i)     effecting a stock split or declaring or
                          paying any dividend consisting of shares of any class
                          of capital stock to the holders of shares of such
                          class of capital stock;

                          (ii)    complying with any specific provision of the
                          terms of the Series A Preferred Stock;

                          (iii) repurchasing any stock of a director, officer,
                          employee or consultant subject to a shareholders'
                          agreement, stock repurchase agreement or stock
                          restriction agreement under which the Corporation has
                          the right or obligation to repurchase such shares in
                          the event of termination of employment or of the
                          consulting arrangement, or other similar
                          discontinuation of relationship; or

                          (iv)    redeeming or repurchasing any shares of
                          common stock (or warrants or options for common
                          stock) held by any holder of debt securities of the
                          Corporation.

                 (c)      Additional Dividends.  After cumulative dividends on
                 the Series A Preferred Stock for all past dividend periods and
                 the then current dividend period shall have been declared and
                 paid or set apart, in accordance with the provisions of this
                 Section 2, the Board may elect to declare additional dividends
                 on the common stock, the holders of the Series A Preferred
                 Stock having no right to participate therein.

         3.      Liquidation, Dissolution or Winding Up.

                 (a)      Treatment at Liquidation, Dissolution or Winding Up.
                 In the event of any liquidation, dissolution or winding up of
                 the Corporation, whether voluntary or involuntary, or in the
                 event of its insolvency, before any distribution or payment is
                 made to any holders of any shares of common stock or any other
                 class or series of capital stock of the Corporation designated
                 to be junior to the Series A Preferred Stock, and subject to
                 the liquidation rights and preferences of any class or series
                 of Preferred Stock designated to be senior to, or on a parity
                 with, the Series A Preferred Stock, the holders of each share
                 of Series A Preferred Stock shall be entitled to be paid first
                 out of the assets of the Corporation available for
                 distribution to holders of the Corporation's capital stock of
                 all classes whether such assets are capital, surplus or
                 earnings, an amount equal to $25.00 per share of Series A
                 Preferred Stock (which amount shall be subject to equitable
                 adjustment whenever there shall occur a stock dividend, stock
                 split, combination, reorganization, recapitalization,
                 reclassification or other similar event involving a change in
                 the capital structure of the Series A Preferred Stock) plus
                 all accrued unpaid dividends thereon, whether or not earned or
                 declared, up to and including the date full payment shall be
                 tendered to the holders of the Series A Preferred Stock with
                 respect to such liquidation, dissolution or winding up.

                 (b)      Pro Rata Payment.  If upon liquidation, dissolution
                 or winding up of the Corporation, the assets of the
                 Corporation available for distribution to its stockholders are
                 insufficient to pay the holders of the Series A Preferred
                 Stock the full amount to which they otherwise would be
                 entitled, the holders of Series A Preferred Stock shall share
                 ratably in any distribution of available assets according to
                 the respective amounts which would otherwise be payable with
                 respect to the shares of Series A Preferred Stock held by them
                 upon such liquidating distribution if all amounts payable on
                 or with respect to said shares were paid in full, based upon
                 the aggregate liquidation value of the Series A Preferred
                 Stock.

                 (c)      Payments to Common Stockholders.  After such payment  
                 shall have been made in full to the holders of the Series A
                 Preferred Stock, or funds necessary for such payment shall 
                 have been set aside by the Corporation in trust for the
                 account of holders of the Series A Preferred 





<PAGE>   8
                 Stock so as to be available for such payment, the remaining
                 assets available for distribution shall be distributed ratably
                 among the holders of the common stock.

                 (d)      Reorganization, Merger or Consolidation.  The
                 provisions of this Section 3 and Section 5(f) shall not apply
                 to any reorganization, merger or consolidation involving (i)
                 only a change in the state of incorporation of the
                 Corporation, (ii) a merger of the Corporation with or into a
                 wholly-owned subsidiary of the Corporation that is
                 incorporated in the United States of America, or (iii) an
                 acquisition by merger, reorganization or consolidation, of
                 which the Corporation is the surviving corporation and
                 operates as a going concern, of another corporation
                 incorporated in the United States.

                 (e)      Distributions Other than Cash.  Whenever the
                 distribution provided for in this Section 3 shall be payable
                 in property other than cash, the value of such distribution
                 shall be the fair market value of such property as determined
                 in good faith by the Board of Directors of the Corporation.

         4.      Non-Voting Status of Preferred Stock.

                 (a)      General.  Except as provided herein or otherwise
                 required by law, the entire voting power of the Corporation
                 shall be vested in the holders of the shares of common stock
                 and the holders of the shares of Series A Preferred Stock
                 shall have no voting power including, without limitation, with
                 respect to any proposed increase or decrease of the aggregate
                 number of authorized shares of Preferred Stock, shall not have
                 the right to participate in any meeting of stockholders and
                 shall not be entitled to any notice of any such meeting and
                 shall not be considered stockholders for the purpose of any
                 election, meeting, consent or waiver of notice, under the
                 provisions of any law now in force or which may hereafter be
                 enacted.

                 (b)      Director Election Right.  Upon failure of the
                 Corporation to pay accrued dividends on the Series A Preferred
                 Stock or to declare and set apart a sum sufficient for the
                 payment thereof, pursuant to Section 2 hereof, for four
                 consecutive dividend periods, the number of directors
                 constituting the Corporation's Board of Directors, at the
                 request of the holders of a majority of the Series A Preferred
                 Stock then outstanding, shall be increased from five to eleven
                 by the amendment of the Corporation's By-laws by the Board of
                 Directors to increase the aggregate number of directors to
                 eleven by increasing the numbers of directors in each class by
                 two.  The vacancies created by this increase shall be filled
                 with members designated by the holders of a majority of the
                 outstanding shares of the Series A Preferred Stock, acting
                 separately as a class, such six directors to be designated as
                 of or as soon as practicable after the date such increase is
                 effective.  Each such additional director shall stand for
                 reelection as of the date that other members of the class of
                 which such director is a member stand for reelection and shall
                 be subject to reelection or replacement solely at the option
                 of the holders of a majority of the Series A Preferred Stock.

                          Any director elected by the holders of the Series A
                 Preferred Stock may be removed during his or her term of
                 office, without cause, by and only by, the affirmative vote or
                 written consent of the holders of a majority of the
                 outstanding shares of the Series A Preferred Stock.

                          Such increase in the number of directors constituting
                 the Corporation's Board of Directors and the right of the
                 holders of the Series A Preferred Stock to appoint such
                 additional directors shall continue following the date on
                 which the increase is first effected until dividends have been
                 declared and paid in accordance with Section 2 hereof for
                 eight consecutive dividend periods.

         5.      Conversion Rights.  The shares of the Series A Preferred Stock
                 shall be converted into shares of common stock in accordance
                 with and subject to the following provisions:

                 (a)      General.  Subject to and in compliance with the
                 provisions of this Section 5, the shares of the Series A
                 Preferred Stock may, at the option of the holder, be converted
                 at any time into fully-paid and non-assessable shares of
                 common stock.  The number of shares of common stock to which a
                 holder of Series A Preferred Stock shall be entitled to
                 receive upon conversion shall be computed by dividing (a) the
                 number of shares of Series A Preferred Stock to be converted
                 times $25.00 per share, by (b) the Conversion Price (as
                 defined in subsection (c) below).

                 (b)      Effect of Conversion.  Each conversion of Series A
                 Preferred Stock will be deemed to have been effected as of the
                 close of business on the date on which the certificate or
                 certificates representing Series A Preferred Stock to be
                 converted have been surrendered at the principal office of the
                 Corporation.  At such time as such conversion has been
                 effected, the rights of the holder of such Series A Preferred
                 Stock as such holder will cease and the person or persons in
                 whose name or names any certificate or certificates for shares
                 of common stock are to be issued upon such conversion will be
                 deemed to have become the holder or holders of record of the
                 shares of common stock represented thereby.

                 (c)      Conversion Price.  The initial "Conversion Price"
                 will be $0.40 per share.  In order to prevent dilution of the
                 conversion rights granted under this subdivision, the
                 Conversion Price will be subject to adjustment from time to
                 time as set forth in this Section 5; provided, however, that
                 there will be no adjustment of the Conversion Price as a
                 result of (i) issuances or deemed issuances of common stock
                 for incentive or compensatory purposes to directors, officers
                 and employees of, and consultants to, the Corporation and its
                 subsidiaries which are from time to time approved by the Board
                 of Directors, including, without limitation, grants of stock
                 options and the issuance of common stock upon the exercise
                 thereof ("Compensatory Stock"), (ii) any split, subdivision or
                 combination of common stock into a different number of
                 securities of the same class ("Split Stock"), or (iii)
                 issuances or deemed issuances of common stock upon exercise or
                 conversion, as the case may be, of warrants issued in
                 connection with any debt of the Corporation or the Series A
                 Preferred Stock ("Converted Stock", and together with
                 Compensatory Stock and Split Stock the "Excluded Stock").
                 Anything herein to the contrary notwithstanding, no adjustment
                 in the Conversion Price shall be required unless such
                 adjustment, either by itself or with other adjustments not
                 previously made, would require a change of at least $0.01 in
                 such price; provided, however, that any adjustment which by
                 reason of this sentence is not required to be made shall be
                 carried forward and taken into account in any subsequent
                 adjustment.

                 (d)      Adjustment of Conversion Price.  If and whenever,
                 after the date of issuance of the Series A Preferred Stock,
                 the Corporation issues or sells, or in accordance with Section
                 5(e) is deemed to have issued or sold, any shares of its
                 common stock (other than Excluded Stock) for a consideration
                 per share less than the Conversion Price in effect immediately
                 prior to the time of such issuance or sale, then forthwith
                 upon such issuance or sale the Conversion Price will be
                 reduced to the conversion price determined by dividing (i) the
                 sum of (A) the product derived by multiplying the Conversion
                 Price in effect immediately prior to such issuance or sale
                 times the number of shares of common stock deemed outstanding
                 immediately prior to such issuance or sale, plus (B) the
                 consideration, if any, received or deemed received by the
                 Corporation upon such issuance or sale, by (ii) the number of
                 shares of common stock deemed outstanding immediately prior to
                 such issuance or sale plus the number of shares of common
                 stock issued or deemed to have been issued in such sale
                 pursuant to this Section 5.

                 (e)      Effect on Conversion Price of Certain Events.  For
                 purposes of determining the adjusted Conversion Price under
                 Section 5(d), the following will be applicable:

                          (1)     Issuance of Rights or Options.  If the
                          Corporation in any manner grants, issues or sells any
                          right, warrant or option to subscribe for or to
                          purchase common stock or any stock or other
                          securities convertible into or exchangeable for
                          common stock (such rights, warrants or options being
                          herein called "Options," and such convertible or
                          exchangeable stock or securities being herein called
                          "Convertible Securities") (other than Excluded Stock)
                          and the price per share for which common stock is
                          issuable upon the exercise of such Options or upon
                          conversion or exchange of any such Convertible
                          Securities is less than the Conversion Price in
                          effect immediately prior to the time of the granting,
                          issuance or sale of such Options, then the total
                          maximum number of shares of common stock issuable
                          upon the exercise of such Options or upon conversion
                          or exchange of the total maximum amount of such
                          Convertible Securities issuable upon the exercise of
                          such Options shall be deemed to be outstanding and to
                          have been issued and sold by the Corporation at the
                          time of the granting of such Options for such price
                          per share.  For purposes of this Section, the "price
                          per share for which common stock is issuable" shall
                          be determined by dividing (A) the total amount, if
                          any, received or receivable by the Corporation as
                          consideration for the granting of such Options, plus
                          the minimum aggregate amount of additional
                          consideration payable to the Corporation upon
                          exercise of all such Options, plus in the case of
                          such Options which relate to Convertible Securities,
                          the minimum aggregate amount of additional
                          consideration, if any, payable to the Corporation
                          upon the issuance or sale of such Convertible
                          Securities and the conversion or exchange thereof, by
                          (B) the total maximum number of shares of common
                          stock issuable upon the exercise of such Options or
                          upon the conversion or exchange of all such
                          Convertible Securities issuable upon the exercise of
                          such Options.  No further adjustment of the
                          Conversion Price shall be made when Convertible
                          Securities are actually issued upon the exercise of
                          such Options or when common stock is actually issued
                          upon the exercise of such Options or the conversion
                          or exchange of such Convertible Securities.

                          (2)     Issuance of Convertible Securities.  If the
                          Corporation in any manner issues or sells any
                          Convertible Securities (other than Excluded Stock)
                          and the price per share for which common stock is
                          issuable upon conversion or exchange thereof is less
                          than the Conversion Price in effect immediately prior
                          to the time of such issue or sale, then the maximum
                          number of shares of common stock issuable upon
                          conversion or exchange of such Convertible Securities
                          shall be deemed to be outstanding and to have been
                          issued and sold by the Corporation at the time of the
                          issuance or sale of such Convertible Securities for
                          such price per share.  For the purposes of this
                          Section, the "price per share for which common stock
                          is issuable" shall be determined by dividing (A) the
                          total amount received or receivable by the
                          Corporation as consideration for the issue or sale of
                          such Convertible Securities, plus the minimum
                          aggregate amount of additional consideration, if any,
                          payable to the Corporation upon the conversion or
                          exchange thereof, by (B) the total maximum number of
                          shares of common stock issuable upon the conversion
                          or exchange of all such Convertible Securities.  No
                          further adjustment of the Conversion Price shall be
                          made when common stock is actually issued upon the
                          conversion or exchange of such Convertible
                          Securities, and if any such issue or sale of such
                          Convertible Securities is made upon exercise of any
                          Options for which adjustments of the Conversion Price
                          had been or are to be made pursuant to other
                          provisions of this Section 5, no further adjustment
                          of the Conversion Price shall be made by reason of
                          such issue or sale.

                          (3)     Change In Option Price or Conversion Rate.
                          If the purchase price provided for in any Option, the
                          additional consideration (if any) payable upon the
                          issue, conversion or exchange of any Convertible
                          Security, or the rate at which any Convertible
                          Security is convertible into or exchangeable for
                          common stock change at any time, and such change is
                          not due solely to the operation of anti-dilution
                          provisions similar in nature to those set forth in
                          this Section 5, the Conversion Price in effect at the
                          time of such change shall be readjusted to the
                          Conversion Price which would have been in effect at
                          such time had such Option or Convertible Security
                          originally provided for such changed purchase price,
                          additional consideration or changed conversion rate,
                          as the case may be, at the time initially granted,
                          issued or sold.

                          (4)     Treatment of Expired Options and Unexercised
                          Convertible Securities.  Upon the expiration of any
                          Option or the termination of any right to convert or
                          exchange any Convertible Security without the
                          exercise of any such Option or right, the Conversion
                          Price then in effect hereunder will be adjusted to
                          the Conversion Price which would have been in effect
                          at the time of such expiration or termination had
                          such Option or Convertible Security, to the extent
                          outstanding immediately prior to such expiration or
                          termination, never been issued.

                          (5)     Calculation of Consideration Received.  If
                          any common stock, Option or Convertible Security is
                          issued or sold or deemed to have been issued or sold
                          for cash, the consideration received therefor will be
                          deemed to be the gross amount received by the
                          Corporation therefor.  If any common stock, Options
                          or Convertible Securities are issued or sold for a
                          consideration other than cash, the amount of the
                          consideration other than cash received by the
                          Corporation will be the fair value of such
                          consideration, except where such consideration
                          consists of securities, in which case the amount of
                          consideration received by the Corporation will be the
                          market price thereof as of the date of receipt.  If
                          any common stock, Option or Convertible Security is
                          issued in connection with any merger in which the
                          Corporation is the surviving company, the amount of
                          consideration therefor will be deemed to be the fair
                          value of such portion of the net assets and business
                          of the non-surviving company as is attributable to
                          such common stock, Options or Convertible Securities,
                          as the case may be.  The fair value of any
                          consideration other than cash and securities will be
                          determined jointly by the Corporation and the holders
                          of a majority of the outstanding Series A Preferred
                          Stock.  If such parties are unable to reach agreement
                          within ten (10) days after the occurrence of an event
                          requiring valuation (the "Valuation Event"), the fair
                          value of such consideration will be determined by an
                          independent appraiser jointly selected by the
                          Corporation and the holders of a majority of the
                          outstanding Series A Preferred Stock; provided if
                          such parties are unable to reach agreement upon the
                          selection of any independent appraiser within fifteen
                          (15) days after the Valuation Event, within twenty-
                          five (25) days after the Valuation Event, the
                          Corporation and the holders of a majority of Series A
                          Preferred Stock then outstanding will each choose a
                          qualified independent appraiser reasonably acceptable
                          to the other party and each such appraiser will
                          deliver in writing its determination of the fair
                          value of such consideration.  If the difference
                          between the two appraisals is 10% or less of the
                          lower amount, the fair value will be the average of
                          such two appraisals.  If the difference between the
                          two appraisals is greater than 10% of the lower
                          amount, the two appraisers will, within thirty-five
                          (35) days after the Valuation Event, jointly choose a
                          third qualified independent appraiser.  Within
                          forty-five (45) days after the Valuation Event, the
                          third appraiser will deliver its determination of
                          fair value and the final determination of the fair
                          value of such consideration will be equal to the
                          average of the two (2) appraisals which are nearest
                          to each other.  The expenses of the appraisers will
                          be paid one-half by the





<PAGE>   12
                          Corporation and one-half by the holders of Series A
                          Preferred Stock (pro rata based on the number of
                          shares of Series A Preferred Stock held).

                          (6)     Treasury Shares.  The number of shares of
                          common stock outstanding at any given time does not
                          include shares owned or held by or for the account of
                          the Corporation or any subsidiary, and the
                          disposition of any shares so owned or held will be
                          considered an issue or sale of common stock.

                          (7)     Record Date.  If the Corporation takes a
                          record of the holders of common stock for the purpose
                          of entitling them (i) to receive a dividend or other
                          distribution payable in common stock, Options or
                          Convertible Securities or (ii) to subscribe for or
                          purchase common stock, Options or Convertible
                          Securities, then such record date will be deemed to
                          be the date of the issue or sale of the shares of
                          common stock deemed to have been issued or sold upon
                          the declaration of such dividend or upon the making
                          of such other distribution or the date of the
                          granting of such right of subscription or purchase,
                          as the case may be.

                 (f)      Subdivision or Combination of Common Stock.  If the
                 Corporation at any time subdivides (by any stock split, stock
                 dividend, recapitalization or otherwise) its outstanding
                 shares of common stock into a greater number of shares, the
                 Conversion Price in effect immediately prior to such
                 subdivision will be proportionately reduced, and if the
                 Corporation at any time combines (by combination, reverse
                 stock split or otherwise) its outstanding shares of common
                 stock into a smaller number of shares, the Conversion Price in
                 effect immediately prior to such combination will be
                 proportionately increased.

                 (g)      Capital Reorganization, Merger or Sale of Assets.  If
                 at any time or from time to time there shall be a capital
                 reorganization of the common stock (other than a subdivision,
                 combination, recapitalization, reclassification or exchange of
                 shares provided for elsewhere in this Section 5) or a merger
                 or consolidation of the Corporation with or into another
                 corporation (other than a merger or reorganization involving
                 only a change in the state of incorporation of the Corporation
                 or the acquisition by the Corporation of other businesses
                 where the Corporation survives as a going concern, as further
                 provided in Section 3(b) hereof), or the sale of all or
                 substantially all of the Corporation's capital stock or assets
                 to any other person, then, as a part of such reorganization,
                 merger, or consolidation or sale, provision shall be made so
                 that the holders of the Series A Preferred Stock shall
                 thereafter be entitled to receive upon conversion of the
                 Series A Preferred Stock the number of shares of stock or
                 other securities or property of the Corporation, or of the
                 successor corporation resulting from such merger,
                 consolidation or sale, to which such holder would have been
                 entitled if such holder had converted its shares of Series A
                 Preferred Stock immediately prior to such capital
                 reorganization, merger, consolidation or sale.  In any such
                 case, appropriate adjustment shall be made in the application
                 of the provisions of this Section 5 to the end that the
                 provisions of this Section 5 (including adjustment of the
                 Conversion Price then in effect and the number of shares of
                 common stock or other securities issuable upon conversion of
                 such shares of Series A Preferred Stock) shall be applicable
                 after that event in as nearly equivalent a manner as may be
                 practicable.

                 (h)      Certificate as to Adjustments; Notice by Corporation.
                 In each case of an adjustment or readjustment of the
                 Conversion Price, the Corporation at its expense will furnish
                 each holder of Series A Preferred Stock with a certificate
                 prepared by the Treasurer or Chief Financial Officer of the
                 Corporation, showing such adjustment or readjustment, and
                 stating in detail the facts upon which such adjustment or
                 readjustment is based.

                 (i)      Exercise of Conversion Privilege.  To exercise its
                 conversion obligations hereunder a holder of Series A
                 Preferred Stock shall surrender the certificate or
                 certificates representing the shares being converted to the
                 Corporation at its principal office, and shall give written
                 notice to the Corporation at that office that such holder
                 elects to convert such shares.  Such notice shall also state
                 the name or names (with address or addresses) in which the
                 certificate or certificates for shares of common stock
                 issuable upon such conversion shall be issued.  The
                 certificate or certificates for shares of Series A Preferred
                 Stock surrendered for conversion shall be accompanied by
                 proper assignment thereof to the Corporation or in blank.  The
                 date when such written notice is received by the Corporation,
                 together with the certificate or certificates representing the
                 shares of Series A Preferred Stock being converted, shall be
                 the "Conversion Date."  As promptly as practicable after the
                 Conversion Date, the Corporation shall issue and shall deliver
                 to the holder of the shares of Series A Preferred Stock being
                 converted, or on its written order, such certificate or
                 certificates as it may request for the number of whole shares
                 of common stock issuable upon the conversion of such shares of
                 Series A Preferred Stock in accordance with the provisions of
                 this Section 5, and cash, as provided in Section 5(i) in
                 respect of any fraction of a share of common stock issuable
                 upon such conversion.


                 (j)      Cash in Lieu of Fractional Shares.  No fractional
                 shares of common stock or scrip representing fractional shares
                 shall be issued upon the conversion of shares of Series A
                 Preferred Stock.  Instead of any fractional shares of common
                 stock which would otherwise be issuable upon conversion of
                 Series A Preferred Stock, the Corporation shall pay to the
                 holder of the shares of Series A Preferred Stock which were
                 converted a cash adjustment in respect of such fractional
                 shares in an amount equal to the same fraction of the market
                 price per share of the common stock (as determined in a
                 reasonable manner prescribed by the Board of Directors) at the
                 close of business on the Conversion Date.  The determination
                 as to whether or not any fractional shares are issuable shall
                 be based upon the aggregate number of shares of Series A
                 Preferred Stock being converted at any one time by any holder
                 thereof, not upon each share of Series A Preferred Stock being
                 converted.

                 (k)      Partial Conversion.  In the event some but not all of
                 the shares of Series A Preferred Stock represented by a
                 certificate(s) surrendered by a holder are converted, the
                 Corporation shall execute and deliver to or on the order of
                 the holder, at the expenses of the Corporation, a new
                 certificate(s) representing the number of shares of Series A
                 Preferred Stock which were not converted.

                 (l)      Reservation of Common Stock.  The Corporation shall
                 at all times reserve and keep available out of its authorized
                 but unissued shares of common stock, solely for the purpose of
                 effecting the conversion of the shares of the Series A
                 Preferred Stock, such number of its shares of common stock as
                 shall from time to time be sufficient to effect the conversion
                 of all outstanding shares of the Series A Preferred Stock
                 (including any shares of Series A Preferred Stock represented
                 by any warrants, options, subscription or purchase rights for
                 Series A Preferred Stock), and if at any time the number of
                 authorized but unissued shares of common stock shall not be
                 sufficient to effect the conversion of all then outstanding
                 shares of the Series A Preferred Stock (including any shares
                 of Series A Preferred Stock represented by any warrants,
                 options, subscriptions or purchase rights for such Preferred
                 Stock), the Corporation shall take such action as may be
                 necessary to increase its authorized but unissued shares of
                 common stock to such number of shares as shall be sufficient
                 for such purpose.





<PAGE>   14
                 (m)      No Reissuance of Preferred Stock.  No share or shares
                 of Series A Preferred Stock acquired by the Corporation by
                 reason of conversion or otherwise shall be reissued, and all
                 such shares shall be cancelled, retired and eliminated from
                 the shares which the Corporation shall be authorized to issue.
                 The Corporation shall from time to time take such appropriate
                 action as may be necessary to reduce the authorized number of
                 shares of the Series A Preferred Stock.

         6.      Optional Redemption.  Commencing at any time on or after the
                 second anniversary of the date of original issuance of the
                 Series A Preferred Stock, the Corporation may, at its sole
                 option, redeem all, but not less than all, outstanding shares
                 of Series A Preferred Stock, at the price and on the terms
                 stated in the following provisions:

                 (a)      Series A Redemption Price.  The redemption price for
                 each share of Series A Preferred Stock redeemed pursuant to
                 this Section 6 shall be $25.00 per share of Series A Preferred
                 Stock, plus all accrued and unpaid dividends, if any, whether
                 or not earned or declared, on such share up to and including
                 the date fixed for redemption (the "Series A Redemption
                 Price").

                 (b)      Adjustment of Series A Redemption Price.  The Series
                 A Redemption Price set forth in this Section 6 shall be
                 subject to equitable adjustment whenever there shall occur a
                 stock split, stock dividend, combination, reorganization,
                 recapitalization, reclassification or other similar event
                 involving a change in the preferred stock.

                 (c)      Notice of Redemption.  If the Corporation elects to
                 redeem the outstanding shares of Series A Preferred Stock
                 pursuant to this Section 6, notice to that effect shall be
                 given to the then holders of the Series A Preferred Stock at
                 least thirty (30) days prior to the redemption date set by the
                 Board of Directors, which notice shall set forth the date
                 fixed for redemption and the Series A Redemption Price.  The
                 notice shall also set forth the manner by which each holder of
                 the Series A Preferred Stock is to surrender to the
                 Corporation, and the place designated for such surrender, its
                 certificate or certificates representing the shares of Series
                 A Preferred Stock to be redeemed.

                 (d)      Surrender of Certificates.  Each holder of shares of
                 Series A Preferred Stock to be redeemed shall surrender the
                 certificate(s) representing such shares to the Corporation at
                 the place designated in the redemption notice received from
                 the Corporation and thereupon the Series A Redemption Price
                 for such shares as set forth in this Section 6 shall be paid
                 to the order of the person whose name appears on such
                 certificate(s) and each surrendered certificate(s) shall be
                 cancelled and retired.

                 (e)      Dividend and Conversion Rights.  From and after the
                 date set for redemption as set forth in the notice provided by
                 the Corporation to the holders of Series A Preferred Stock, no
                 shares of Series A Preferred Stock shall be entitled to any
                 further dividends pursuant to Section 2 hereof or to the
                 conversion provisions set forth in Section 5 hereof.

         7.      No Dilution or Impairment.  The Corporation will not, by
                 amendment of its Articles of Incorporation or through any
                 reorganization, transfer of capital stock or assets,
                 consolidation, merger, dissolution, issue or sale of
                 securities or any other voluntary action, avoid or seek to
                 avoid the observance or performance of any of the terms of the
                 Series A Preferred Stock set forth herein, but will at all
                 times in good faith assist in the carrying out of all such
                 terms and in the taking of all such action as may be necessary
                 or appropriate in order to protect the rights of the holders
                 of the Series A Preferred Stock against dilution or other
                 impairment.  Without limiting the generality of the foregoing,
                 the Corporation (a) will not increase the par value of any
                 shares of stock receivable on the conversion of the Series A
                 Preferred Stock above the amount payable





<PAGE>   15
                 therefor on such conversion, (b) will take all such action as
                 may be necessary or appropriate in order that the Corporation
                 may validly and legally issue fully paid and nonassessable
                 shares of stock on the conversion of all Series A Preferred
                 Stock from time to time outstanding, and (c) will not transfer
                 all or substantially all of its properties and assets to any
                 other person (corporate or otherwise), or consolidate with or
                 merge into any other person or permit any such person to
                 consolidate with or merge into the Corporation (if the
                 Corporation is not the surviving person), unless such other
                 person shall expressly assume in writing and will be bound by
                 all the terms of the Series A Preferred Stock set forth
                 herein.

         8.      Notices of Record Date.  In the event of:  (a)  any capital
                 reorganization of the Corporation, any reclassification or
                 recapitalization of the capital stock of the Corporation, any
                 merger or consolidation of the Corporation, or any transfer of
                 all or substantially all of the assets of the Corporation to
                 any other Corporation, or any other entity or person, or (b)
                 any voluntary or involuntary dissolution, liquidation or
                 winding up of the Corporation, then and in each such event the
                 Corporation shall mail or cause to be mailed to each holder of
                 Series A Preferred Stock a notice specifying (i) the date on
                 which any such reorganization, reclassification,
                 recapitalization, transfer, consolidation, merger,
                 dissolution, liquidation or winding up is expected to become
                 effective, and (ii) the time, if any, that is to be fixed, as
                 to when the holders of record of common stock (or other
                 securities) shall be entitled to exchange their shares of
                 common stock (or other securities) for securities or other
                 property deliverable upon such reorganization,
                 reclassification, recapitalization, transfer, consolidation,
                 merger, dissolution, liquidation or winding up.  Such notice
                 shall be mailed by first class mail, postage prepaid, at least
                 five (5) days prior to the date specified in such notice on
                 which such action is to be taken.

         9.      Registration of Transfer.  The Corporation will keep at its
                 principal office a register for the registration of Series A
                 Preferred Stock.  Upon the surrender of any certificate
                 representing Series A Preferred Stock at such place, the
                 Corporation will, at the request of the record holder of such
                 certificate, execute and deliver (at the Corporation's
                 expense) a new certificate or certificates in exchange
                 therefor representing in the aggregate the number of shares of
                 Series A Preferred Stock represented by the surrendered
                 certificate.  Each such new certificate will be registered in
                 such name and will represent such number of shares of Series A
                 Preferred Stock as is requested by the holder of the
                 surrendered certificate and will be substantially identical in
                 form to the surrendered certificate; provided, however, that
                 any transfer shall be subject to any applicable restrictions
                 on the transfer of such shares and the payment of any
                 applicable transfer taxes, if any, by the holder thereof.

         10.     Replacement.  Upon receipt of evidence reasonably satisfactory
                 to the Corporation (an affidavit of the registered holder will
                 be satisfactory) of the ownership and the loss, theft,
                 destruction or mutilation of any certificate evidencing shares
                 of Series A Preferred Stock, and in the case of any such loss,
                 theft or destruction, upon receipt of indemnity reasonably
                 satisfactory to the Corporation, or, in the case of any such
                 mutilation, upon surrender of such certificate, the
                 Corporation will (at its expense) execute and deliver in lieu
                 of such certificate a new certificate of like kind
                 representing the number of shares of Series A Preferred Stock
                 represented by such lost, stolen, destroyed or mutilated
                 certificate and dated the date of such lost, stolen, destroyed
                 or mutilated certificate."

         B.      The foregoing amendment was originally adopted by the Board of
Directors of the Corporation on September 7, 1995, subject to approval by the
shareholders of the Corporation of Article Fifth (B), and was ratified
following receipt of shareholder approval on November 16, 1995.  Shareholder

                                PROMISSORY NOTE


$9,000,000.00                                                   January 25, 1996
                                                           Springfield, Virginia


         1.      AGREEMENT TO PAY.  For value received, the undersigned, Sarnia
Corporation, a Virginia corporation (hereinafter referred to as "Borrower"),
whose mailing address is:  6850 Versar Center, Springfield, Virginia 22151,
hereby agrees and promises to pay to order of IDS Life Insurance Company, a
Minnesota corporation, its endorses, successors and assigns (hereinafter
referred to as "Lender"), at its principal office and mailing address:  733
Marquette Avenue, Minneapolis, Minnesota 55402, Attention:  Real Estate Loan
Management, Unit #401, or such other address as Lender may from time to time
designate, the principal sum of Nine Million and 00/100 Dollars ($9,000,000.00)
or so much as may from time to time be disbursed hereon, together with interest
on the unpaid principal balance hereof from the date hereof until said amounts
shall have been paid in full at the rate provided for herein and all other sums
due as provided herein, payable in lawful money of the United States of
America, which shall be legal tender for public and private debt at the time of
payment (the "Loan").

         2.      INTEREST RATE.  The outstanding principal balance hereof shall
bear interest at the rate of seven and three fourths percent (7.75%) per annum
(the "Regular Rate") computed on the basis of the actual days elapsed on the
assumption that each month contains thirty (30) days and each year contains
three hundred sixty (360) days.

         3.      MONTHLY PAYMENT.  Principal and interest upon this Note shall
be paid as follows:

         (a)     On the date hereof, interest only at the Regular Rate shall be
         due and payable on (the unpaid principal balance hereof or Initial
         Principal Balance) equal to accrued interest from the date of
         disbursement hereunder through the last day of January, 1996.

         (b)     On the first day of March 1996, and continuing on the first
         day of each month thereafter through and including January, 2003,
         interest at the Regular Rate and principal payments shall be made in
         eighty- three (83) equal installments of Seventy-One Thousand One
         Hundred Twenty-Four and 55/100 Dollars ($71,124.55) each (based on a
         twenty-two (22) year amortization of the principal amount of this Note
         commencing on February 1, 1996).

         (c)     On the first day of February, 2003 (the "Maturity Date"), a
         final payment shall be due and payable in the amount of the entire
         unpaid principal and interest on this Note.

         (d)     This is a balloon note, and on the Maturity Date a substantial
         portion of the principal amount of this Note will remain unpaid by the
         monthly payments above required.

         (e)     All payments shall be applied first to late charges due
         hereunder, second to any prepayment fee due hereunder, third to
         accrued interest at the rate then in effect under the terms hereof,
         and fourth to principal.  However, upon occurrence of an Event of
         Default (as hereinafter defined), any monies received shall be
         applied, at the option and discretion of Lender, to any sums due under
         the Note or instrument securing this Note, including, without
         limitation, attorneys' fees and other costs of collection as provided
         herein.

         (f)     All payments hereunder which are due on a Saturday, Sunday or
         holiday shall be deemed to be payable on the next business day.





<PAGE>   2
         4.      DEFAULT INTEREST RATE.  Upon the earlier to occur of (a) the
date on which the indebtedness evidenced hereby is accelerated by Lender, or
(b) the date on which an Event of Default (as hereinafter defined) occurs which
is not cured within thirty (30) days, or (c) upon non-payment at the Maturity
Date, the interest rate payable hereunder shall thereafter increase and shall
be payable on the whole of the unpaid principal balance at a rate equal to the
lesser of (i) four percent (4%) per annum in excess of the rate of interest
then in effect under the terms of this Note or (ii) the highest rate of
interest permitted under the laws of the Commonwealth of Virginia (hereinafter
referred to as the "Default Rate").  Interest on this Note at the Default Rate
shall be immediately due and payable without notice or demand.  The Default
Rate shall be applicable whether or not Lender has exercised its option to
accelerate the maturity of this Note and declare the entire unpaid principal
indebtedness to be due and payable.  The Default Rate shall continue until
Borrower has cured all defaults as permitted herein, Borrower has paid all
indebtedness evidenced by this Note in full, or all foreclosure proceedings
have been completed and all redemption periods have expired, whichever shall
occur first.  This provision shall not be deemed to excuse a default and shall
not be deemed a waiver of any other rights Lender may have, including the right
to declare the entire unpaid principal balance and accrued interest immediately
due and payable.

         5.      LATE CHARGE.  Any monthly installment payment, including
monthly payments of escrows for real estate taxes, special assessments and/or
insurance premiums required by the "Deed of Trust" (as hereinafter defined),
not made by Borrower within ten (10) days of the due date shall be subject to a
late payment charge equal to five percent (5%) of the amount of such monthly
payment.  The late charge shall apply individually to all payments past due
with no daily adjustment and shall be used to defray the cost of Lender
incident to collecting such late payment.  This provision shall not be deemed
to excuse a late payment or be deemed a waiver of any other rights Lender may
have, including the right to declare the entire unpaid principal balance and
accrued interest immediately due and payable.

         6.      SECURITY.  This Note is given to evidence an actual loan in
the above amount and is the Note referred to in and secured by:

         given by Borrower, as grantor, to Lender, as beneficiary, of a
         contemporaneous date herewith, encumbering certain real property and
         the improvements thereon located in the County of Fairfax,
         Commonwealth of Virginia (the "Premises").

         (b)     An Assignment of Leases (the "Assignment of Leases") and
         Assignment of Rents (the "Assignment of Rents") given by the Borrower,
         as assignor, to Lender, as assignee, of a contemporaneous date
         herewith, assigning to assignee all of the rents, issues, profits and
         leases of the Premises.

         (c)     Other collateral security agreements (the "Security Document")
         given by Borrower or guarantors of the Loan to Lender, all of a
         contemporaneous date herewith.

         (d)     A Guaranty and Indemnity Agreement (the "Guaranty Agreement")
         given by Borrower, and Versar, Inc., a Delaware corporation
         ("Guarantor") to Lender of a contemporaneous date herewith
         guaranteeing payment of the Indebtedness Guaranteed (as defined in the
         Guaranty Agreement).

         (e)     A Hazardous Materials Indemnity Agreement (the "Hazardous
         Materials Agreement") given by Borrower and Guarantor to Lender of a
         contemporaneous date herewith providing indemnification to Lender for
         claims, losses, liabilities, etc. for matters arising out of Hazardous
         Materials or violation of Laws (as those two terms are more
         particularly defined in the Hazardous Materials Agreement).

Reference is hereby made to the Deed of Trust, the Assignment of Leases, the

Trust, or if there is a default (subject to applicable grace or cure periods)

Section and not otherwise.

         not in part during the entire term hereof provided that any such
         prepayment, for whatever reason, whether voluntary or involuntary,
         shall be subject to a prepayment fee which shall be computed as a
         percentage of the amount of the principal prepaid, and which shall be
         payable as follows:

<TABLE>
<CAPTION>
         Prepayment During Loan Years                               Prepayment Fee
         ----------------------------                               --------------
                 <S>                                                         <C>
                 1, 2 & 3                                                    One year's interest

                    5                                                                3%
                    6                                                                2%
                    7                                                                1%
</TABLE>

         (b)     No prepayment fee shall be due if the indebtedness evidenced
         hereby is paid in full during the last one hundred eighty (180) days
         prior to the Maturity Date.

         (c)     At the option of Lender, this Note is also subject to
         mandatory prepayment, without prepayment fee of any kind, upon certain
         events set forth in the Deed of Trust, if Lender at its option does
         not make proceeds of insurance and condemnation awards available for
         repair or restoration of the Premises.

         (d)     Prepayments (other than prepayments pursuant to subsection (c)
         above) shall be made only upon advance written notice of at least
         thirty (30) days to Lender and shall be made on a regularly scheduled
         installment payment date.  Notice of prepayment shall not suspend nor
         reduce required installment payments.

         (e)     No prepayment fee shall be due on any insurance or
         condemnation proceeds that Lender does not make available for
         restoration or repair.

         (f)     In the event Lender does not make insurance proceeds available
         for reconstruction, Borrower shall have the right to prepay this Note
         in full without a prepayment fee.





<PAGE>   4
         (g)     In the event Borrower shall default under the terms of the
         Loan Documents and Lender shall accelerate this Note as part of a
         foreclosure proceeding or otherwise and Borrower shall then tender
         payment of this Note in full, such tender shall constitute prepayment
         and the fee provided for in this Section shall be due.

         (h)     For purposes of this Section, prepayment during the initial
         partial month shall be considered prepayment during the first Loan
         Year and the prepayment fee calculated accordingly.

Borrower hereby expressly agrees that such prepayment fee constitutes
additional bargained-for consideration given by Borrower to Lender in order to
induce Lender to make the loan to Borrower.

         10.     PAYMENT UPON AN EVENT OF DEFAULT.  Upon the occurrence of an
Event of Default and following acceleration of maturity hereof by Lender, a
tender of payment of or entry of judgment for the amount necessary to satisfy
the entire unpaid principal balance due and payable shall be deemed to
constitute an attempted evasion of the aforesaid restrictions on the right of
prepayment and shall be deemed a prepayment hereunder, and such a payment or
judgment must, therefore, include the prepayment fee then in effect under the
terms hereof.  Lender shall have the right to include and bid in such
prepayment fee as an amount due to Lender in connection with any foreclosure
sale.

         11.     EFFECT OF APPLICATION OF INSURANCE OR CONDEMNATION PROCEEDS.
Notwithstanding anything herein to the contrary, in the event that Lender is
unwilling to make the proceeds of a condemnation award or insurance settlement
on the Premises available for repair or restoration and elects to apply such
award or settlement towards the reduction of the principal balance of this Note
pursuant to the terms of the Deed of Trust, and the proceeds thereof do not pay
in full the balance outstanding on this Note, then the unpaid principal balance
shall be reamortized over the remaining portion of the amortization period and
the debt service payments set forth in Section 3(b) hereof shall be reduced
accordingly.

         12.     COSTS OF COLLECTION.  Borrower agrees that if, and as often
as, this Note is placed in the hands of an attorney for collection or to defend
or enforce any of Lender's rights hereunder, or under the Deed of Trust, the
Assignment of Leases or any other Security Document or Loan Document securing
payment of this Note, Borrower will pay to Lender its attorneys' and
paralegals' fees nd costs, including, without limitation, all fees and costs
incurred in litigation, mediation, arbitration, bankruptcy and administrative
proceedings, and appeals therefrom, and all court costs and other expenses,
including, without limitation, appraisal fees and costs of environmental
review, incurred in connection therewith.

         13.     TIME.  Time is of the essence of this Note and each of the
provisions hereof.

         14.     GOVERNING LAW.  This Note shall be governed by the laws of the
Commonwealth of Virginia.

         15.     INTEREST LIMITATION.  All agreements between Borrower and
Lender are hereby expressly limited so that in no contingency or event
whatsoever, whether by reason of acceleration of maturity of the indebtedness
evidenced hereby or otherwise, shall the amount paid or agreed to be paid to
Lender for the use, forbearance, loaning or detention of the indebtedness
evidenced hereby exceed the maximum permissible under applicable law.  If from
any circumstance whatsoever, fulfillment of any provision hereof or of the Deed
of Trust, Assignment of Leases or any other Security Document or Loan Document
at any time given the amount paid or agreed to be paid shall exceed the maximum
permissible under applicable law, then, the obligation to be fulfilled shall
automatically be reduced to the limit permitted by applicable law, and if from
any circumstance Lender should ever receive as interest an amount which would
exceed the highest lawful rate of interest, such amount which would be in
excess of such highest lawful rate of interest shall be applied to the
reduction of the principal balance evidenced hereby and not to the payment of
interest.  This provision shall control every other provision of all agreements
between Borrower and Lender and shall be binding upon and available to any
subsequent holder of this Note.

         evidenced hereby immediately due and payable, shall be construed as a
         novation of this Note or shall operate as a waiver or prevent the
         subsequent exercise of any or all such rights.

         (b)     Acceptance by Lender of any portion or all of any sum payable
         hereunder, whether before, on or after the due date of such payment
         shall not be a waiver of Lender's right either to require prompt
         payment when due of all other sums payable hereunder or to exercise
         any of Lender's rights, powers and remedies hereunder or under the
         Loan Documents.  A waiver of any right in writing on one occasion
         shall not be construed as a waiver of Lender's rights to insist
         thereafter upon strict compliance with the terms hereof without
         previous notice of such intention being given to Borrower, and no
         exercise of any right by Lender shall constitute or be deemed to
         constitute an election of remedies by Lender precluding the subsequent
         exercise by Lender of any or all of the rights, powers and remedies
         available to it hereunder or under the Loan Documents, or at law or in
         equity.  Borrower expressly waives the benefit of any statute or rule
         of law or of equity now provided, or which may hereafter be provided,
         which would produce a result contrary to, or in conflict with, the
         foregoing.

deemed outstanding hereunder and to have been received by Borrower as of the
date of such mailing, wire transfer, or other delivery and until repaid,
notwithstanding the fact that such funds may not at any time have been remitted
by such escrows to Borrower or for its benefit

Borrower with the prior written consent of Lender; (b) all security deposits,
prepaid rents, income and profits (i) collected with respect to the Premises
more than thirty (30) days in advance, (ii) collected with respect to periods
after Lender has exercised its rights to such rents, income and/or profits and
(iii) regardless of default, for any fee or consideration for lease termination
not consented to by Lender; (c) damages sustained by Lender as a direct or
indirect result of any fraud and/or misrepresentation of Borrower or its
shareholders; (d) losses sustained by Lender from hazardous substances and/or
environmental pollution in connection with the Premises; (e) real estate taxes
and insurance premiums which have accrued to the date Lender has received a
deed in lieu of foreclosure to the Premises or the date the Premises are sold
pursuant to a judicial foreclosure (for purposes of this Section, such date is
referred to as the "Transfer Date"), less any money held by Lender as of the
Transfer Date in an escrow established as a reserve for such payments and less
any additional money actually collected from tenants of the Premises which are
payable under such tenants' leases as their share of the real estate taxes or
insurance premiums for the Premises accruing prior to the Transfer Date; and
(f) any damages sustained by Lender as a result of claims made by tenants of
the Premises arising out of matters occurring prior to the date on which Lender
succeeds to the interest of Borrower under the leases, unless such tenants have
agreed in writing that Lender is not responsible for such claims in the event
Lender succeeds to the interest of Borrower.  Nothing herein contained shall

person or party to this Note shall affect or release the joint and several
liability of any other person or party.  Lender may at its option enforce this
Note against one or all of Borrowers, and Lender shall not be required to
resort to enforcement against each Borrower and the failure to proceed against
or join any Borrower shall not affect the joint and several liability of any
other Borrower.

changed or discharged orally, but only by an agreement in writing signed by
Borrower and Lender; and any oral waiver, change or discharge of any term or

                                IMPORTANT NOTICE

         THIS INSTRUMENT CONTAINS A CONFESSION OF JUDGMENT PROVISION WHICH
CONSTITUTES A WAIVER OF IMPORTANT RIGHTS YOU MAY HAVE AS A DEBTOR AND ALLOWS A
CREDITOR TO OBTAIN A JUDGMENT AGAINST YOU WITHOUT ANY FURTHER NOTICE.

                                   TERM NOTE


$1,500,000.00                                                   January 25, 1996
                                                                Washington, D.C.


         FOR VALUE RECEIVED, SARNIA CORPORATION, a Virginia corporation (the
"Borrower"), promises to pay to the order of THE RIGGS NATIONAL BANK OF
WASHINGTON, D.C., a national banking association (the "Lender"), at 808 17th
Street, N.W., Washington, D.C. 20006, or at such other place as the holder
hereof may from time to time designate in writing, in lawful money of the
United States of America, without defense, setoff or counterclaim, the
principal sum of ONE MILLION FIVE HUNDRED THOUSAND AND 00/100 DOLLARS
($1,500,000.00), together with interest as described below on the principal
balance hereof from time to time outstanding, all in accordance with the
following terms and provisions:

         1.      INTEREST RATE.  The unpaid principal balance of this Term Note
(as the same may be amended, modified or supplemented from time to time, the
"Note") outstanding from time to time shall bear interest at a per annum rate
equal to the Prime Rate (as defined below) plus 1.00%.  The term "Prime Rate"
shall mean the rate of interest reported in The Wall Street Journal newspaper
in its "Money Rates" column as the "Prime Rate," the higher or highest such
rate, changing when and as such rate shall change.  If The Wall Street Journal
shall cease to publish the "Prime Rate," then "Prime Rate" shall mean that rate
announced by the Lender from time to time as its prime rate of interest.  The
Prime Rate (determined by either method) is not necessarily the lowest rate of
interest charged by the Lender on loans to its customers.  The Borrower
acknowledges that, with respect to all matters relevant hereto, a certificate
signed by an officer of the Lender setting forth the Prime Rate in effect on
any applicable date shall be binding and conclusive.  Accrued interest shall be
computed for actual days elapsed on the basis of a year of 365 or 366 days, as
applicable.

         2.      INTEREST PAYMENTS.  Accrued interest shall be paid monthly in
arrears on the first day of each calendar month, beginning on February 1, 1996,
and on the Maturity Date (as defined below).

         3.      PRINCIPAL PAYMENTS.  The principal sum of this Note shall be
paid in monthly installments of $22,727.28 each, due on the first day of each
calendar month, beginning on July 1, 1997, and continuing on the first day of
each succeeding calendar month thereafter until January 1, 2003 (the "Maturity
Date").  The entire unpaid principal balance hereof together with all accrued
and unpaid interest shall be due and payable in full on the Maturity Date.

         4.      PREPAYMENT.  This Note may be prepaid in whole or in part at
any time, without premium or penalty.  Partial prepayments shall be applied to
installments due hereunder in the inverse order of their maturities.

         5.      APPLICATION OF PAYMENTS.  Payments made hereunder shall be
applied first to accrued late charges, next to accrued interest hereon and any
remainder to the principal balance hereof.

         6.      LOAN DOCUMENTS.  The performance of the Borrower's obligations
hereunder are guaranteed by Versar, Inc. and its subsidiaries (the
"Guarantors") pursuant to the Guaranty Agreement of even date herewith (as





<PAGE>   2
the same may be amended, modified or supplemented from time to time, the
"Guaranty") from the Guarantors in favor of the Lender.  This Note, the
Guaranty and any other document executed or delivered by the Borrower in
connection herewith shall be referred to herein as the "Loan Documents."

         7.      REPRESENTATIONS AND WARRANTIES:  The Borrower represents and
warrants that:

                 (a)      Organization.  The Borrower is a corporation duly
organized, validly existing and in good standing under the laws of the state of
its incorporation, and is duly qualified as a foreign corporation and in good
standing under the laws of each others jurisdiction in which such qualification
is required.  The Borrower has no subsidiaries.

                 (b)      Execution and Delivery.  The Borrower has the
corporate power, and has taken all the necessary corporate actions, to execute
and deliver and perform its obligations under this Note, and this Note is a
binding obligation of the Borrower, enforceable in accordance with its terms.

                 (c)      Corporate Power.  The Borrower has the corporate
power and authority to own its properties and to carry on its business as now
being conducted.

                 (d)      Financial Statements.  All financial statements and
information delivered to the Lender by the Borrower (including, without
limitation, the Borrower's balance sheet and income statement for the period of
nine months ended on September 30, 1995), were prepared in accordance with
generally accepted accounting principles, are correct and complete and present
fairly the financial condition, and reflect all known liabilities, contingent
or otherwise, of the Borrower as of the dates of such statements and
information, and since such dates no material adverse change in the assets,
liabilities, financial condition, business or operations of the Borrower has
occurred.

                 (e)      Taxes.  All tax returns and reports of the Borrower
and its predecessors required by law to be filed have been duly filed, and all
taxes, assessments, other governmental charges or levies (other than those
presently payable without penalty or interest and those that are being
contested in good faith in appropriate proceedings) upon the Borrower and its
predecessors and upon any of their properties, assets, income or franchises,
that are due and payable have been paid.

                 (f)      Litigation.  There is no action, suit or proceeding
pending or, to the knowledge of the Borrower, threatened against or affecting
the Borrower that, either in any case or in the aggregate, may result in any
material adverse change in the business, properties or assets or in the
condition, financial or otherwise, of the Borrower or that may result in any
material liability on the part of the Borrower, or that questions the validity
of this Note or any action taken or to be taken in connection with this Note.

                 (g)      No Breach.  The execution and delivery of this Note,
and compliance with the provisions of this Note, will not conflict with or
violate any provisions of law or conflict with, result in a breach of, or
constitute a default under the charter or bylaws of the Borrower, any judgment,
order or decree binding on the Borrower, or any other agreements to which the
Borrower is a party.

                 (h)      No Defaults.  The Borrower is not in default with
respect to any debt, direct or indirect.

                 (i)      Compliance.  The Borrower is in compliance in all
material respects with all applicable laws and regulations, including, without
limitation, the Employee Retirement Income Security Act of 1974, as amended
("ERISA").





<PAGE>   3
                 (j)      Approvals.  No authorizations, approvals or consents
of, and no filings and registrations with, any governmental or regulatory
authority or agency are necessary for the execution, delivery or performance of
this Note by the Borrower.

                 (k)      Title to Assets.  The Borrower has good and
marketable title to all of its assets, subject only to the liens and security
interests permitted by this Note.

                 (l)      Use of Proceeds.  The proceeds of the loan evidenced
hereby shall be used only for the purpose of refinancing existing debt of the
Borrower.  No proceeds of such loan shall be used to purchase or carry any
margin stock, as such term is defined in Regulation U of the Board of Governors
of the Federal Reserve System.

         8.      COVENANTS.  In consideration of credit extended or to be
extended by the Lender, the Borrower covenants and agrees as follows:

                 (a)      Financial Information.  The Borrower shall deliver to
the Lender, (1) within 90 days after the close of each of its fiscal year,
audited financial statements prepared in accordance with generally accepted
accounting principles, including a balance sheet and statements of income,
stockholders' equity and cash flow, prepared by an independent certified public
accountant acceptable to the Lender, who shall render an unqualified opinion
with respect to such financial statements; (2) within 45 days after the
conclusion of each quarter of each fiscal year of the Borrower, financial
statements of the Borrower, including a balance sheet and income statement,
prepared in accordance with generally accepted accounting principles and
certified to be accurate by the president, treasurer or chief financial officer
of the Borrower, and (3) from time to time, such other financial data and
information regarding the Borrower as the Lender reasonably may request.

                 (b)      Taxes.  The Borrower shall pay or cause to be paid
all taxes, assessments or governmental charges lawfully levied or imposed on or
against it and its properties prior to the time they become delinquent;
provided that this covenant shall not apply to any tax, assessment or charge
that is being contested in good faith and with respect to which adequate
reserves as determined in good faith by the Borrower have been established and
are being maintained.

                 (c)      Compliance with Laws.  The Borrower shall comply with
all applicable laws and regulations, including, without limitation, ERISA.

                 (d)      Maintain Existence.  The Borrower shall maintain its

condition, comply at all times with the provisions of all leases to which it is
a party and maintain adequate insurance for all of its property with
financially sound and reputable insurers.  The Borrower shall remain in the
same line of business as it is in on the date of this Note and shall not enter
into any new lines of business without the prior written consent of the Lender.

                 (e)      Notices.  As soon as it has actual knowledge, the
Borrower shall notify the Lender of (1) the institution or threat of any
material litigation or administrative proceeding of any nature involving the
Borrower, and (2) the occurrence of an Event of Default under this Note, or any
event that, with the giving of notice or lapse of time, or both, would
constitute an Event of Default.

                 (f)      Books and Records.  The Borrower shall maintain
complete and accurate books of account and records.  The principal books of
account and records shall be kept and maintained at 6850 Versar Center,
Springfield, Virginia.  The Borrower shall not remove such books of account and
records without giving the Lender at least 30 days' prior written notice.  The
Borrower, upon reasonable notice from the Lender, shall permit the Lender, or
any officer, employee or agent designated by the Lender, to examine the books
of account and records maintained by the Borrower, and agrees that the Lender
or such officer, employee or agent may audit and verify





<PAGE>   4
the books and records.  All accounting records and financial reports furnished
to the Lender pursuant to this Note shall be maintained and prepared in
accordance with generally accepted accounting principles consistently applied.

                 (g)      Liens.  Without the prior written consent of the
Lender, the Borrower shall not create, incur, assume or permit to exist any
mortgage, deed of trust, assignment, pledge, lien, security interest, charge or
encumbrance, including, without limitation, the right of a vendor under a
conditional sale contract or the lessor under a capitalized lease
(collectively, the "Liens") of any kind or nature in or upon any of its assets
except:

                          (1)     Liens created or deposits made that are
incidental to the conduct of the business of the Borrower, that are not
incurred in connection with any borrowing or the obtaining of any credit and
that do not and will not interfere with the use by the Borrower of any of its
assets in the normal course of its business or materially impair the value of
such assets for the purpose of such business;

                          (2)     Liens securing indebtedness to the Lender;
and

                          (3)     Liens on existing real estate assets that
secure indebtedness not exceeding a principal sum of $9,000,000 in the
aggregate at any time outstanding.

                 (h)      Debt.  Without the prior written consent of the
Lender, the Borrower shall not incur or permit to exist any debt for borrowed
funds, the deferred purchase price of goods or services or capitalized lease
obligations, except for (1) trade debt incurred in the ordinary course of
business, (2) indebtedness to the Lender, and (3) other indebtedness not
exceeding a principal sum of $9,000,000 in the aggregate at any time
outstanding.

                 (i)      Contingent Liabilities.  Without the prior written
consent of the Lender, the Borrower shall not guarantee, endorse, become
contingently liable upon or assume the obligation of any person or entity, or
permit any such contingent liability to exist, except by the endorsement of
negotiable instruments for deposit or collection or similar transactions in the
ordinary course of business.

                 (j)      Sale of Assets. Without the prior written consent of
the Lender, the Borrower shall not sell, lease, assign or otherwise dispose of
any of its assets except for (1) leases in the ordinary course of business of
real estate owned by the Borrower, and (2) the disposition of assets that are
not longer needed or useful in the Borrower's business.

                 (k)      Mergers and Acquisitions.  Without the prior written
consent of the Lender, the Borrower shall not merge or consolidate with, or
acquire all or substantially all of the assets, stock, partnership interests or
other ownership interests of, any other person or entity.

                 (l)      Loans and Advances.  Without the prior written
consent of the Lender, the Borrower shall not make any loan or advance to any
affiliate, shareholder, director, officer or employee of the Borrower, or any
other person or entity, except for the creation of accounts receivable in the
ordinary course of business on terms that are no less favorable than would
apply in an arm's-length transaction.

                 (m)      Dividends.  Without the prior written consent of the
Lender, the Borrower shall not (1) declare or pay any dividends or make any
other payments on its capital stock or (2) issue, redeem, repurchase or retire
any of its capital stock, or make any distribution to its stockholders,
provided that, as long as the Borrower is not in default hereunder, the
Borrower may pay dividends at an annual rate of $2.625 per share to the holders
of its Series A Preferred Stock outstanding on the date hereof.

written consent of the Lender, the Borrower shall not form any subsidiary,
become a general or limited partner in any partnership or become a party to a
joint venture.  If the Lender grants its consent to the formation or
acquisition of a subsidiary by the Borrower, the Borrower shall cause each such
subsidiary to perform and observe all of the covenants contained in this Note.

         9.      EVENTS OF DEFAULT.  Each of the following shall constitute an
"Event of Default" under this Agreement:

                 (a)      Failure to Pay.  If the Borrower fails to make when
due any installment or other payment owing to the Lender under the terms of
this Note and such failure shall continue for a period of ten days after
written notice of such failure has been given to the Borrower by the Lender
(which may be a computer- generated late payment notice);

                 (b)      Failure to Give Notices.  If the Borrower fails to
give the Lender any notice required by Paragraph 8(e) of this Note within ten
days after it has actual knowledge of the event giving rise to the obligation
to give such notice;

                 (c)      Failure to Permit Inspections.  If the Borrower
refuses to permit the Lender to inspect the Borrower's books and records in
accordance with the provisions of Paragraph 8(f) of this Note;

                 (d)      Failure to Observe Other Covenants.  If the Borrower
fails to perform or observe any other term, covenant, warranty or agreement
contained in this Note and such failure shall continue for a period of 30 days
after written notice of such failure has been given to the Borrower;

                 (e)      Defaults under Guaranty.  If an event of default
shall occur under the Guaranty shall not be cured within any applicable grace
period;

                 (f)      Breach of Representation.  Discovery that any
representation or warranty made or deemed made by the borrower in this Note or
in any statement or representation made in any certificate, report or opinion
delivered pursuant to this Note or in connection with any borrowing under this
Note was materially untrue when made or deemed made, or is breached in any
material respect;

                 (g)      Voluntary Bankruptcy.  If the Borrower or a Guarantor
makes an assignment for the benefit of creditors, files a petition in
bankruptcy, petitions or applies to any tribunal for any receiver or any
trustee of the Borrower or a Guarantor or any substantial part of the property
of the Borrower or a Guarantor, or commences any proceeding relating to the
Borrower or a Guarantor under any reorganization, arrangement, composition,
readjustment, liquidation or dissolution law or statute of any jurisdiction,
whether in effect now or after this Note is executed;

                 (h)      Involuntary Bankruptcy.  If, within 60 days after the
filing of a bankruptcy petition or the commencement of any proceeding against
the Borrower or a Guarantor seeking any reorganization, arrangement,
composition, readjustment, liquidation, dissolution or similar relief under any
present or future statute, law or regulation, the proceeding shall not have
been dismissed, or, if within 60 days, after the appointment, without the
consent or acquiescence of the Borrower or a Guarantor, of any trustee,
receiver or liquidator of the borrower or a Guarantor or all or any substantial
part of the properties of the Borrower or a Guarantor, the appointment shall
not have been vacated;

                 (i)      Cross Default.  If, as a result of default, any
present or future obligations of the Borrower or a Guarantor to the Lender or

occurs in the financial or business condition of the Borrower or any Guarantor;

                 (k)      Judgment.  If a judgment, attachment, garnishment or
other process in excess of $50,000 is entered against the Borrower or any
Guarantor and is not vacated or bonded within 30 days after entry;

                 (l)      Change in Control.  If any person or entity or two or
more persons or entities acting in concert shall acquire beneficial ownership
(within the meaning of Rule 13d-3 of the Securities and Exchange Commission)

                 (n)      Termination of Guaranty.  If a Guarantor gives
written notice to the Lender purporting to terminate the obligations of such

         10.     REMEDIES UPON DEFAULT.  Upon the occurrence of an Event of
Default hereunder, the entire principal balance hereof, all accrued interest
thereon and all other amounts payable hereunder shall become immediately due
and payable at the option of the Lender.  Any delay by the Lender in exercising
or any failure of the Lender to exercise the aforesaid option to accelerate
with respect to an Event of Default shall not constitute a waiver of its right
to exercise such option with respect to that or any subsequent Event of
Default.  Acceleration of maturity, once claimed hereunder by the holder hereof
may be rescinded, at such holder's option, by written acknowledgement to that
effect, but the tender and acceptance of partial payment or partial performance
alone shall not in any way affect or rescind such acceleration of maturity.
After the occurrence of an Event of Default, interest shall accrue on all
amounts due hereunder at a rate of 2.0% per annum above the rate or rates of
interest then payable hereunder.

         11.     LATE CHARGE.  The Borrower shall pay to the Lender a late
charge equal to 5% of any amount due hereunder that is not received by the
Lender within ten days after the date on which such amount is due.

         12.     WAIVER; EXTENSIONS.  Presentment, demand, notice of dishonor,
protest and the benefits of the homestead and all other exemptions provided
debtors are hereby waived.  The Borrower agrees that it shall remain liable for
the payment hereof notwithstanding any agreement for the extension of the due
date of any amount payable hereunder made by the Lender after the maturity
thereof.

         13.     CONFESSION OF JUDGMENT.  Upon the occurrence of an Event of
Default hereunder, the Borrower does hereby duly constitute and appoint Robert
C. Roane, C. Christopher Giragosian, Linda Lemmon Najjoum, or Bradley R.
Duncan, or any of them, as the true and lawful attorney-in-fact for the
Borrower in its name, place and stead, to confess judgment against the
borrower, in favor of the Lender in the amount of the unpaid principal balance
of this Note together with any accrued and unpaid interest and late charges and
reasonable attorneys' fees and costs, to consent to jurisdiction and to
acknowledge service of process necessary in such a confession, in the Circuit
Court of Fairfax County, Virginia, or in the United States District Court for
the Eastern District of Virginia, Alexandria Division, hereby ratifying and
confirming the acts of said attorney-in-fact as if done by the Borrower.  No
single exercise of the foregoing power to confess judgment shall be deemed to
exhaust the power, whether or not any such exercise shall be held by any court
to be invalid, voidable or void, but the power shall continue undiminished, and
it may be exercised from time to time as often as the Lender shall elect, until
such time as the Lender shall have received payment in full of all indebtedness
of the Borrower to the Lender, together with all other costs and indebtedness
of the Borrower under this Note.

to such collection or an Event of Default hereunder.

                                IMPORTANT NOTICE

         THIS INSTRUMENT CONTAINS A CONFESSION OF JUDGMENT PROVISION WHICH
CONSTITUTES A WAIVER OF IMPORTANT RIGHTS YOU MAY HAVE AS A DEBTOR AND ALLOWS A
CREDITOR TO OBTAIN A JUDGMENT AGAINST YOU WITHOUT ANY FURTHER NOTICE.

                               DEED OF TRUST NOTE


$500,000.00                                                     January 25, 1996
                                                                Washington, D.C.


         FOR VALUE RECEIVED, SARNIA CORPORATION, a Virginia corporation (the
"Borrower"), promises to pay to the order of THE RIGGS NATIONAL BANK OF
WASHINGTON, D.C., a national banking association (the "Lender"), at 808 17th
Street, N.W., Washington, D.C. 20006, or at such other place as the holder
hereof may from time to time designate in writing, in lawful money of the
United States of America, without defense, setoff or counterclaim, the
principal sum of FIVE HUNDRED THOUSAND AND 00/100 DOLLARS ($500,000.00),
together with interest as described below on the principal balance hereof from
time to time outstanding, all in accordance with the following terms and
provisions:

         1.      INTEREST RATE.  The unpaid principal balance of this Deed of
Trust Note (as the same may be amended, modified or supplemented from time to
time, the "Note") outstanding from time to time shall bear interest at a per
annum rate equal to the Prime Rate (as defined below) plus 2.00%.  The term
"Prime Rate" shall mean the rate of interest reported in The Wall Street
Journal newspaper in its "Money Rates" column as the "Prime Rate" and, if more
than one rate or a range of rates is reported as the "Prime Rate," the higher
or highest such rate, changing when and as such rate shall change.  If The Wall
Street Journal shall cease to publish the "Prime Rate," then "Prime Rate" shall
mean that rate announced by the Lender from time to time as its prime rate of
interest.  The Prime Rate (determined by either method) is not necessarily the
lowest rate of interest charged by the Lender on loans to its customers.  The
Borrower acknowledges that, with respect to all matters relevant hereto, a
certificate signed by an officer of the Lender setting forth the Prime Rate in
effect on any applicable date shall be binding and conclusive.  Accrued
interest shall be computed for actual days elapsed on the basis of a year of
365 or 366 days, as applicable.

         2.      INTEREST PAYMENTS.  Accrued interest shall be paid monthly in
arrears on the first day of each calendar month, beginning on February 1, 1996,
and on the Maturity Date (as defined below).

         3.      PRINCIPAL PAYMENTS.  The principal sum of this Note shall be
paid in monthly installments of $41,667 each, due on the first day of each
calendar month, beginning on February 1, 1996, and continuing on the first day
of each succeeding calendar month thereafter until January 1, 1997 (the
"Maturity Date").  The entire unpaid principal balance hereof together with all
accrued and unpaid interest thereon shall be due and payable in full on the
Maturity Date.  The Borrower acknowledges and agrees that any extension of the
Maturity Date granted by the Lender (which may be granted or denied by the
Lender in its sole and absolute discretion) may not extend the Maturity Date
beyond July 1, 1997, unless an extension beyond such date is approved in
writing by IDS Life Insurance Company, a Minnesota corporation ("IDS").

         4.      PREPAYMENT.  This Note may be prepaid in whole or in part at
any time, without premium or penalty.  Partial prepayments shall be applied to
installments due hereunder in the inverse order of their maturities.





<PAGE>   2
         5.      APPLICATION OF PAYMENTS.  Payments made hereunder shall be
applied first to accrued late charges, next to any amounts due under the Loan
Documents (as defined below), next to accrued interest hereon and any remainder
to the principal balance hereof.

         6.      LOAN DOCUMENTS.  The performance of the Borrower's obligations
hereunder is secured by (a) a Deed of Trust, Assignment and Security Agreement
of even date herewith (as the same may be amended, modified or supplemented
from time to time, the "Deed of Trust") from the Borrower to C. Christopher
Giragosian and Sandra P. Mozingo, as trustees, granting a second lien on
certain property owned by the Borrower and located in Fairfax County, Virginia,
and more particularly described in the Deed of Trust (the "Property").  This
Note, the Deed of Trust and any other document executed or delivered by the
Borrower in connection herewith shall be referred to herein as the "Loan
Documents."

         7.      DEFAULT.  An Event of Default shall occur hereunder if (a) the
borrower shall fail to pay any amount due under this Note and such failure
shall continue for a period of seven days, or (b) if a default or an "Event of
Default" occurs under a Loan Document and is not cured within any applicable
grace period.  Upon the occurrence of an Event of Default hereunder, the entire
principal balance hereof, all accrued interest thereon and all other amounts
payable hereunder and under the Loan Documents shall become immediately due and
payable at the option of the Lender.  Any delay by the Lender in exercising or
any failure of the Lender to exercise the aforesaid option to accelerate with
respect to an Event of Default shall not constitute a waiver of its right to
exercise such option with respect to that or any subsequent Event of Default.
Acceleration of maturity, once claimed hereunder by the holder hereof may be
rescinded, at such holder's option, by written acknowledgement to that effect,
but the tender and acceptance of partial payment or partial performance alone
shall not in any way affect or rescind such acceleration of maturity.  After
the occurrence of an Event of Default, interest shall accrue on all amounts due
hereunder at a rate of 2.0% per annum above the rate or rates of interest then
payable hereunder.  Notwithstanding the foregoing, or any term or provision
contained elsewhere herein or in any other Loan Document to the contrary, an
Event of Default hereunder or under any Loan Document shall not be deemed to
have occurred until IDS shall have received notice thereof and an additional
twenty (20)-day period after actual receipt of such notice by IDS shall have
expired and IDS fails within such time period to cure such Event of Default.

         8.      LATE CHARGE.  The Borrower shall pay to the Lender a late
charge equal to 5% of any amount due hereunder that is not received by the
Lender within ten days after the date on which such amount is due.

         9.      WAIVER; EXTENSIONS.  Presentment, demand, notice of dishonor,
protest and the benefits of the homestead and all other exemptions provided
debtors are hereby waived.  The Borrower agrees that it shall remain liable for
the payment hereof notwithstanding any agreement for the extension of the due
date of any amount payable hereunder made by the Lender after the maturity
thereof.

         10.     CONFESSION OF JUDGMENT.  Upon the occurrence of an Event of
Default hereunder, the borrower does hereby duly constitute and appoint Robert
C. Roane, C. Christopher Giragosian, Linda Lemmon Najjoum, or Bradley R.
Duncan, or any of them, as the true and lawful attorney-in-fact for the
Borrower in its name, place and stead, to confess judgment against the
Borrower, in favor of the Lender in the amount of the unpaid principal balance
of this Note together with any accrued and unpaid interest and late charges and
reasonable attorneys' fees and costs, to consent to jurisdiction and to
acknowledge service of process necessary in such a confession, in the Circuit
Court of Fairfax County, Virginia, or in the United States District Court for
the Eastern District of Virginia, Alexandria Division, hereby ratifying and
confirming the acts of said attorney-in-fact as if done by the Borrower.  No
single exercise of the foregoing power to confess judgment shall be deemed to
exhaust the power, whether or not any such exercise shall be held by any court
to be invalid, voidable or void, but the power shall continue undiminished, and
it may be exercised from time to time as often as the Lender shall elect, until
such time as





<PAGE>   3
the Lender shall have received payment in full of all indebtedness of the
Borrower to the Lender, together with all other costs and indebtedness of the
Borrower under the Loan Documents.  Any judgment lien so obtained shall be
subject to the first lien rights and interests of IDS under the first lien deed
of trust from the Borrower securing its obligations to IDS.

         11.     WAIVER OF JURY TRIAL.  THE LENDER AND THE BORROWER IRREVOCABLY
WAIVE ALL RIGHTS TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM
ARISING OUT OF OR RELATING TO THIS NOTE AND ANY OTHER LOAN DOCUMENT, THE
TRANSACTIONS CONTEMPLATED IN THE LOAN DOCUMENTS, THE DOCUMENTS AND INSTRUMENTS
EVIDENCING OR SECURING ANY PRIOR INDEBTEDNESS OF THE BORROWER TO THE LENDER AND
ANY RELATED DOCUMENTS, AND THE BORROWER FURTHER WAIVES ANY RIGHT TO FILE ANY
SUCH COUNTERCLAIM AS PART OF ANY ACTION OR PROCEEDING FILED OR MAINTAINED BY
THE LENDER TO COLLECT ANY INDEBTEDNESS OF ANY PARTY TO THE LENDER OR TO
EXERCISE ANY RIGHTS OR REMEDIES AVAILABLE TO THE LENDER UNDER THE DOCUMENTS
EVIDENCING OR SECURING SUCH INDEBTEDNESS, AT LAW, IN EQUITY OR OTHERWISE IN
CONNECTION WITH OR RELATED TO SUCH INDEBTEDNESS.

         12.     COLLECTION COSTS AND EXPENSES.  The Borrower shall pay all
reasonable costs, fees and expenses (including court costs and reasonable
attorneys' fees) incurred by the Lender in collecting or attempting to collect
any amount that becomes due hereunder or in seeking legal advice with respect
to such collection or an Event of Default hereunder.

         13.     NOTICES.  All notices, requests, demands and other

         4       Representations and Warranties by Each Investor.  In
connection with each Investor's purchase of the Preferred Stock, each Investor
hereby acknowledges as follows:

                 4.1      Purchased for Own Account.  The Preferred Shares are
being purchased for the Investor's own account without the participation of any
other person, with the intent of holding the Preferred Shares for investment
and without the intent of participating, directly or indirectly, in a
distribution of any of the Preferred Stock and not with a view to, or for
resale in connection with, any distribution of the Preferred Stock or any
portion thereof, nor is the Investor aware of the existence of any distribution
of the Company's securities.

                 4.2      No Representation About Value.  The Investor is not
acquiring the Preferred Shares based upon any representation, oral or written,
by any person with respect to the future value of, or income from, the
Preferred Stock, but rather upon an independent examination and judgment as to
the prospects of the Company.

                 4.3      No Public Advertisements.  The Preferred Stock was
not offered to the Investor by means of publicly disseminated advertisements or
sales literature, nor is the Investor aware of any offers made to other persons
by such means.

                 4.4      Investor Provided Adequate Information.  The Company
has delivered to the Investor sufficiently in advance of the Closing Date for
the Investor carefully to evaluate the contents thereof a copy of each of (i)
its Form 10-K for the fiscal year ended June 30, 1995 filed with the Securities
and Exchange Commission (the "Commission"), which is hereto attached as Exhibit
C, (ii) its Form 10-Q for the fiscal quarter ended September 30, 1995 filed
with the Commission, which is attached as Exhibit D, (iii) its most recent
Annual Report to Shareholders for the fiscal year ended June 30, 1995, which is
attached as Exhibit E and (iv) the Company's proxy statement dated October 19,
1995 relating to the annual meeting of shareholders held on November 16, 1995,
which is attached as Exhibit F.

                 4.5      All Information Necessary.  The Investor has asked
all questions he or she desires to ask of the Company and its officers and
directors including, but not limited to, questions concerning the Preferred
Stock and the Company's business plan, financial position and capitalization,
and the Investor has received answers to all such questions to the Investor's
satisfaction.

                 4.6      No Obligation to Register.  The Investor understands
and agrees that the Company shall be under no obligation to register the
Securities or to comply with any exemption available for the sale of the
Securities without registration.  The Company is under no obligation to act in
any manner so as to maintain the availability of Rule 144 under the Securities
Act with respect to the Securities.

                 4.7      Certificates for Preferred Stock.  The Investor
understands and agrees that the following legend indicating that the Preferred
Shares have not been registered under the Securities Act or any state
securities laws and referring to the restrictions on transferability and sale
of the Preferred Shares will be placed on the certificate or certificates
delivered to the Investor, or any substitute therefor; that a similar legend
may be placed by the Company on any of the other Securities; and that any
transfer agent of the Company will be instructed to require compliance
therewith:

         THE SHARES OF PREFERRED STOCK REPRESENTED BY THIS CERTIFICATE (THE
         "SECURITIES") HAVE BEEN ISSUED OR SOLD IN RELIANCE ON AN EXEMPTION
         FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933 (THE "1933 ACT")
         AND APPLICABLE STATE SECURITIES LAWS.  THE SECURITIES HAVE BEEN TAKEN
         FOR INVESTMENT PURPOSES ONLY AND NOT WITH THE VIEW TO THE DISTRIBUTION
         THEREOF AND MAY NOT BE OFFERED FOR SALE, PLEDGED, SOLD OR TRANSFERRED
         OTHER THAN (i) PURSUANT TO AN EFFECTIVE REGISTRATION OR AN EXEMPTION
         THEREFROM UNDER THE 1933 ACT AND APPLICABLE STATE

         SECURITIES LAWS AND (ii) UPON RECEIPT BY THE ISSUER OF EVIDENCE
         SATISFACTORY TO IT OF COMPLIANCE WITH THE 1933 ACT AND ANY OTHER
         APPLICABLE FEDERAL OR STATE SECURITIES LAWS.  THE ISSUER SHALL BE
         ENTITLED TO REQUIRE AN OPINION OF COUNSEL SATISFACTORY TO IT WITH
         RESPECT TO COMPLIANCE WITH THE ABOVE LAWS PRIOR TO EFFECTING ANY
         TRANSFER THEREOF.

                 4.8      Investor to Bear Risk.  The Investor acknowledges
that he or she must continue to bear the economic risk of the investment in the
Preferred Stock for an indefinite period.

                 4.9      The Company's Reliance.  The Investor acknowledges
that reliance by the Company on exemptions from registration of the Preferred
Stock is predicated in part on the Investor's representations set forth in this
Agreement.

         5.      Representations and Warranties by the Company.  The Company
hereby represents and warrants to each Investor as follows:

                 5.1      Organization, Standing, etc.  The Company is a
corporation duly organized, validly existing and in good standing under the
laws of the Commonwealth of Virginia, and has all requisite power and authority
to carry on its business and to enter into this Agreement and to issue the
Preferred Stock.

                 5.2      Capital Stock.  The authorized capital stock of the
Company currently consists of twenty million (20,000,000) shares of common
stock and one million (1,000,000) shares of undesignated preferred stock, of
which 30,000 shares have been designated Series A Cumulative Convertible
Preferred Stock.  Four million, five hundred seventy two thousand, five hundred
and forty-five (4,572,545) shares of common stock are issued and outstanding,
and such shares are duly authorized, validly issued, fully paid and
nonassessable.  No shares of preferred stock are currently outstanding.  The
offer, issuance and sale of such shares of common stock were (a) effected in
accordance with the registration and prospectus delivery requirements of the
Securities Act or an exemption therefrom, (b) registered or qualified (or were
exempt from registration or qualification) under the registration or
qualification requirements of all applicable state securities laws, and (c) to
the best of the Company's knowledge, accomplished in conformity with all other
federal and applicable state securities laws, rules and regulations.  The
Company has reserved a total of three hundred thousand (300,000) shares of
common stock for issuance to directors, employees and service providers
pursuant to the terms of its existing employee benefit plans, in all cases
subject to approval of the Board of Directors of the Company.  Except as
expressly provided in this Agreement or in accordance with the terms of the
Preferred Stock, the Company has no outstanding subscription, option, warrant,
call, contract, demand, commitment, convertible security or other instrument,
agreement or arrangement of any character or nature whatever under which the
Company is or may be obligated to issue common stock, preferred stock or other
equity securities of any kind.

                 5.3      Preferred Stock.  The Preferred Stock has been duly
authorized and, when issued and paid for pursuant to the terms of this
Agreement, will be duly authorized, validly issued, fully paid and
nonassessable, will have the rights, preferences and privileges and be subject
to terms specified in Exhibit B and will be free and clear of all Liens (as
hereinafter defined) and restrictions, other than Liens that might have been
created by Investors and restrictions on transfer imposed by (i) Section 6
hereof, (ii) applicable state securities laws and (iii) the Securities Act.

                 5.4      Reservation.  The Conversion Stock has been reserved
by the Company from among duly authorized common stock of the Company and when
the Conversion Stock is issued it will be duly authorized, validly issued,
fully paid and nonassessable common stock of the Company and free and clear of
all Liens and restrictions, other than Liens that might have been created by
Investors and restrictions imposed by (i) Section 6 hereof, (ii) applicable
state securities laws and (iii) the Securities Act.





<PAGE>   4
                 5.5      Corporate Acts and Proceedings.  All corporate acts
and proceedings required for the authorization, execution and delivery of this
Agreement, the offer, issuance and delivery of the Preferred Stock and the
Conversion Stock and the performance of this Agreement and the terms of the
Preferred Stock have been lawfully and validly taken or will have been so taken
prior to the Closing.

                 5.6      Changes.  Since the respective effective dates of the
documents delivered to each Investor as referenced in Section 4.4, no material
event of the type requiring disclosure under the Securities Act, the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), or applicable state
securities laws that has not been disclosed to the Investors in the documents
referenced in Section 4.4 or otherwise has occurred.

         6.      Non-transfer Covenants of Each Investor.  Each Investor
covenants to the Company and agrees that the Investor will not offer for sale,
sell or transfer the Securities other than (i) pursuant to an effective
registration under all applicable state securities laws or in a transaction
which is otherwise in compliance with such laws; (ii) pursuant to an effective
registration under the Securities Act or in a transaction otherwise in
compliance with the Securities Act; and (iii) upon delivery to the Company of
evidence satisfactory to it of compliance with the applicable securities laws
of other jurisdictions.  The Company may, if it so desires, refuse to permit
the transfer of any Securities unless the request for transfer is accompanied
by an opinion of counsel acceptable to the Company to the effect that neither
the sale nor the proposed transfer will result in any violation of the
Securities Act or the securities laws of any other jurisdiction.

         7.      Conditions of Parties' Obligations.

                 7.1      Conditions of Investors' Obligations.  The obligation
of each Investor to purchase and pay for the Preferred Stock that it has agreed

applicable state securities laws, and rules and regulations related to the
foregoing.

                          (b)     Truthfulness of Representations and
Warranties.  The representations and warranties of each Investor under this

                               AMENDMENT NO. 1 TO
                       PREFERRED STOCK PURCHASE AGREEMENT



THIS AMENDMENT NO. 1 to the PREFERRED STOCK PURCHASE AGREEMENT (the
"Agreement") by and between SARNIA CORPORATION (the "Company") and
______________, dated December 11, 1995.

WHEREAS:  the Board of Directors of the Company has approved changes requested
by certain Investors  to the terms of the Series A Cumulative Convertible
Preferred Stock at meetings held on February 8, 1996 and May 9, 1996.

NOW THEREFORE, in consideration of the mutual agreements and other good and
valuable consideration the Company and ______________ hereby agree to amend the
Agreement as follows:

1.  That the first sentence of Section 2(a) of the Form of Designation of
Series A Cumulative Convertible Preferred Stock, Exhibit B, be, and it is
hereby, amended to read in its entirety as follows:

                 The holders of the outstanding shares of Series A Preferred
                 Stock shall be entitled to receive preferential cumulative
                 dividends accruing, whether or not earned and whether or not
                 paid, at the annual rate of $2.625 per share in the case of
                 Series A Preferred Stock, payable in arrears on the first day
                 of March, June, September and December of each year.

2. The third paragraph of the Form of Designation of Series A Cumulative
Convertible Preferred Stock, Exhibit B, Section 2(a) be, and it is hereby,
amended to read in its entirety as follows:

                 Such dividends on the Series A Preferred Stock shall be
                 cumulative so that if such dividends with respect to any
                 previous or current annual dividend period, at the annual rate
                 specified above, shall not have been paid or declared and a
                 sum sufficient for payment thereof set apart, the deficiency
                 shall first be fully paid before any dividend or other
                 distribution shall be paid or declared and set apart for the
                 common stock.  Payment to the holders of Series A Preferred
                 Stock for any deficiency in the payment of dividends shall be
                 applied to all accrued and unpaid dividends such that those
                 dividends most in arrears shall be paid first.  Upon any
                 conversion of the Series A Preferred Stock under Section 5
                 hereof, all such accrued and unpaid dividends to and until the
                 date of such conversion shall become due and payable and shall
                 be paid upon delivery of shares of common stock to the holder
                 of the shares of Series A Preferred Stock being converted
                 under Section 5.

3. That Section 5(c) of the Form of Designation of Series A Cumulative
Convertible Preferred Stock, Exhibit B, be, and it is hereby, amended to read
in its entirety as follows:

                 (c) Conversion Price.  The initial "Conversion Price" will be
                 $0.40 per share.  In order to prevent dilution of the
                 conversion rights granted under this subdivision, the
                 Conversion Price will be subject to adjustment from time to
                 time as set forth in this Section 5; provided, however, that
                 there will be no adjustment of the Conversion Price as a
                 result of (i) issuances or deemed





<PAGE>   7
                 issuances of Common Stock for incentive or compensatory
                 purposes to directors, officers and employees of, and
                 consultants to, the Corporation and its subsidiaries which are
                 from time to time approved by the Board of Directors,
                 including, without limitation, grants of stock options and the
                 issuance of common stock upon the exercise thereof
                 ("Compensatory Stock"), or (ii) issuances or deemed issuances
                 of Common Stock upon exercise or conversion, as the case may
                 be, of warrants issued in connection with any debt of the
                 corporation or the Series A Preferred Stock ("Converted
                 Stock", and together with Compensatory Stock, the "Excluded
                 Stock").  Anything herein to the contrary notwithstanding, no
                 adjustment in the Conversion Price shall be required unless
                 such adjustment, either by itself or with other adjustments
                 not previously made, would require a change of at least $0.01
                 in such price; provided, however, that any adjustment which by
                 reason of this sentence is not required to be made shall be
                 carried forward and taken into account in any subsequent
                 adjustment.

4.  That Section 6(d) of the Form of Designation of Series A Cumulative
Convertible Preferred Stock, Exhibit B, be, and it is hereby, amended to read
in its entirety as follows:

                 (d) Surrender of Certificates.  Each holder of shares of
                 Series A Preferred Stock to be redeemed shall surrender the
                 certificate(s) representing such shares to the Corporation at
                 the place designated in the redemption notice received from
                 the Corporation and, on the date of such surrender, the Series
                 A Redemption Price for such shares as set forth in this
                 Section 6 shall be paid to the order of the person whose name
                 appears on such certificate(s) and each surrendered
                 certificate(s) shall be cancelled and retired.


IN WITNESS WHEREOF, the parties hereto have signed this Amendment No. 1 the
date set forth below.
