ITEM 1.     BUSINESS

General

EA Engineering, Science, and Technology, Inc. is an international consulting
firm specializing in the fields of energy, the environment, and health and
safety. Through its network of more than 20 branch and satellite offices and its
analytical and international operations, EA provides scientific, engineering,
economic, analytical, and management solutions to industrial, utility, and
government clients.

As of August 31, 1997, the Company's organizational structure consisted of the
parent company, EA Engineering, Science, and Technology, Inc. ("EA") and its
wholly-owned subsidiaries, EA International, Inc. and EA Financial, Inc., and EA
Financial's wholly-owned subsidiaries, EA Global, Inc. and EA Engineering,
Science, and Technology de Mexico, S.A. de C.V. EA International, Inc., a
Maryland corporation, was incorporated in fiscal 1997 to provide environmental
services on a fully diversified basis throughout the world. The entities are
collectively referred to herein as the "Company."

The Company was founded in 1973 and initially was engaged in environmental
assessment and permitting related to power plant siting and expansion. Since
that time, in response to market opportunities and conditions, the Company
expanded both its services and client base. Today, we provide services in areas
ranging from air permitting and process safety, to water quality and resources
management. Since its founding, EA has performed more than 65,000 projects for
clients in the United States and in more than 30 nations abroad.

Historically, the demand for EA's services was largely driven by the myriad of
federal, state and local environmental enactments and regulations impacting the
Company's clients. A great deal of cleanup activity and progress have been
generated as a result of those laws and regulations--in 1996 the U.S.
environmental market reported revenues of $181,000,000,000. However, as with all
regulatory-driven businesses, the industry, and in turn, the Company's
performance is inextricably linked to the pace and intensity with which the
regulations are written, promulgated, and enforced. During the past several
years, the regulatory pace has slowed resulting in an increasingly competitive
environmental market.

More recently, the demand for the Company's services have been stimulated by
new, more business-oriented factors, including the recognition that it is more
cost-effective to prevent pollution and minimize waste than to remediate it as a
toxic emission. Additionally, many clients now see environmental strategy as a
method of increasing global competitiveness and enhanced profitability. EA
believes that this strategic shift will stimulate opportunity for its
business-oriented consulting services in both the domestic and international
markets.

In our role as an advocate and strategic resource to our clients, EA provides
the management perspective and technical skills to anticipate, identify, address
and resolve those energy, environmental, health and safety issues affecting
their business performance and profitability.

                                        1

Services

EA provides consulting services to clients in the areas of energy, environment,
and health and safety. The Company's primary service areas are Air Quality
Management and Process Engineering, Analytical Laboratory Services,
Ecotoxicology and Bioassessment, Risk Sciences and Management, Sediment and
Dredging, Site Characterization and Remediation, Solid Waste, and Water Quality
and Water Resources Management, and Health and Safety Reviews, Energy Planning
and Audits, Due Diligence Reviews, and Strategic Planning of Environmental
Issues.

The multi-faceted nature of most environmental problems, however, requires a
cross-section of professionals to provide an integrated solution, and strict
classification by service area is not practical for most of the Company's
projects. In providing its services, EA has developed certain remedial and
analytical technologies and processes for the mitigation and control of
environmental damage and risks. In addition, we assist clients in responding to
issues raised by regulatory agencies and community groups. All of the service
areas are part of the vertically-integrated capabilities that the Company may
offer its clients.

The Company's services normally are performed by a team of scientists,
engineers, planners and economists and include a combination of the following:
<TABLE>

<S> <C>
   o    Consultation to determine the nature and scope, and development and
        implementation of solutions to mitigate potential environmental, energy,
        or health and safety problems.
   o    On-site collection of samples.
   o    On-site monitoring and measurement of discharges and emissions.
   o    Analysis of samples in the Company's laboratories or in its mobile testing units.
   o    Evaluation of environmental or human health risks.
   o    Development and engineering design of a system or facility for
        monitoring, controlling or eliminating the problem.
   o    Preparation of reports for regulatory agencies.
   o    Participation and representation of clients in public and regulatory hearings.
   o    Engineering certification of design specifications.
   o    Implementation of remedial action.
</TABLE>

The Company's contracts are generally undertaken on a time and material, fixed
price, or cost plus fixed fee basis. Fixed price contracts and certain time and
material and cost plus contracts with upset limits require EA to bear the risk
of cost overruns. Most of the Company's contracts provide that the client may at
any time cancel any portion of the work not yet performed.

======================================== ============= ============  ===========
</TABLE>


During fiscal 1997, the volume of the Company's work continued to be
predominately from fixed price and time and materials contracts. The Company
considers this to be an industry trend whereby clients transfer additional risk
to the prime contractor and, in turn, the Company transfers additional risk to
its subcontractors, when applicable.

In general, the Company's contracts vary in length from one month to ten years
and require performance of a particular project within the contractually
specified time frame. Although the Company holds certain federal contracts with
options for longer durations, most of these contracts require exercise of annual
renewals by the client. A substantial portion of EA's contracts represent the
provision of separate services required from time-to-time by ongoing clients.

Clients

EA provides services to industrial, utility, and government clients both
directly and indirectly through work performed for architects/engineers,
engineer/contractors, law firms, and financial institutions. The Company's goal
is to assist its clients in achieving their business and growth objectives as
costeffectively and dependably as possible.

During fiscal 1997, the Company provided services to more than 450 industrial,
utility, and government clients involving more than 1,500 projects in the
private sector and 460 projects in the federal government sector. Although more
private sector projects were performed, the portion of net revenue provided by
the federal government was 50%, 53%, and 64% for the fiscal year 1997, 1996 and
1995, respectively. The Company believes that a diversified mix of business
revenue derived from each of its client sectors will help ensure its continuing
financial success. To achieve this goal, the Company has established a business
development program focused on specific client sectors. Those sectors are:
federal government, state and local governments, industry (for example, pulp and
paper, oil and gas, chemical), and electric utility.

Although a significant portion of net revenue was derived from agencies of the
federal government, the Company's services are performed for many different
departments, and in many different regions of the country, thereby reducing the
financial risks associated with the delays or cancellation of any particular
contract. Therefore, in management's opinion, the loss of any one of the
Company's clients within its major revenue generating sector would not have a
material effect on operations or profitability.

Sales and Marketing

The Company markets its services from its headquarters in Hunt Valley, Maryland
and through its network of branch and satellite offices located in and around
major metropolitan cities across the United States. The Company employs a
variety of business development and marketing techniques, including one-on-one
client meetings and presentations, hosting and participating in industry
seminars, responding to formal requests for proposals, initiating direct-mail
programs, and establishing an ongoing public relations/technical article program
within industry trade journals.

A significant portion of new business arises from prior client engagements.
Clients frequently expand the scope of work to include follow-on complementary
activities and new activities and often refer us to their colleagues at other
locations. Additionally, the Company has an active business development program
to identify new clients that have not yet engaged its services. The Company
often teams with other consulting firms, or provides its services as a
subcontractor to larger architect/engineer or engineer/contractor firms. The
Company tracks prospective business through an interactive opportunity pipeline
network.

The Company employs a matrix approach involving branch operations, Client
Sectors Directors, and National Technical Directors to maximize the
effectiveness of its sales and marketing organization. The Company's market
sectors are federal government, state and local governments, industry, and
electric utility. The Company's product lines are Air Quality Management
Services and Process Engineering, Alternative Fuels, Analytical Laboratory
Services, Ecotoxicology and Bioassessment, Process Safety and Risk Management,
Risk-Based Environmental Decision-Making, Sediment Management, Site
Characterization and Remediation, Solid Waste Management Services, and Water
Quality and Water Resources Management.

Backlog

At August 31, 1997, the Company's total contract backlog was approximately
$48,400,000 compared to contract backlog of $63,700,000 at August 31, 1996. The
Company's net contract backlog (total less estimated subcontractor costs) was
approximately $38,900,000 at the end of fiscal 1997 compared to approximately
$52,500,000 at the end of fiscal 1996. The Company expects that approximately
80% of

                                        4

<PAGE>



this backlog will be completed in fiscal 1998. The Company's total contract
backlog attributable to federal government contracts as of August 31, 1997 was
$34,000,000 ($26,000,000, net) compared to $41,000,000 ($32,000,000, net) a year
earlier.

There can be no assurance, however, that work under any of these contracts will
be authorized or that work once authorized will not be cancelled. Generally,
these contracts provide for a fixed percentage of profit based on estimated
costs. In the event of cancellation, the Company is entitled to recover its
incurred costs and associated profit. Terminations and cancellations of
government contracts have not been material in the past. The level of backlog
may fluctuate during each year, and accordingly, the backlog at any point in
time does not necessarily reflect near-term anticipated operating results.
Reliance on major government contracts subjects the Company to risks associated
with public budgetary restrictions and uncertainties, discrepancies between
awarded contract amounts and actual revenues, and cancellation at the option of
the government. The Company attempts to mitigate these risks by staffing only to
meet reasonably anticipated average workloads, by using subcontractors to handle
peak work loads, and by obtaining termination benefit contract provisions.
Cancellation of any of the Company's major government contracts, however, could
have a material adverse effect on the Company.

As the amount of work available from federal agencies declines and becomes more
competitive, the Company is shifting its marketing efforts to the industrial,
utility, and state and local levels. Particular attention will be given to
expanding the overall management consulting practice in the energy and
environment areas with emphasis also on health and safety issues.

The Company also provides services on major long-term private sector contracts
under continuing service agreements that provide for work on a task basis. Upon
receipt of related authorizations, the work is included in contract backlog.
Because such specific authorizations are generally for periods considerably
shorter than the duration of the period the Company expects to perform services
for a particular client, management believes that its backlog figures are not
necessarily indicative of its future revenue.

Employees

As of August 31, 1997, the Company had approximately 560 full-time employees
compared to approximately 720 full-time employees at August 31, 1996. The
decrease in staff was a result of staff reductions in overhead positions and
excess capacity in technical staff. Most of the Company's employees are engaged
in performing scientific, engineering, remediation, and consulting services; the
remainder provide executive, administrative, and other support services. The
Company also hires part-time or temporary personnel to meet seasonal needs or
the requirements of a particular contract. EA's staff includes professional
engineers, biologists, chemists, geologists, industrial hygienists, public
health scientists, regulatory specialists, toxicologists, industrial planners,
computer scientists, and business managers.

The Company has reinvigorated and invested in training and mentoring programs to
facilitate a "continuing learning" process within the firm. In 1997, the Company
instituted several programs, including project manager training, sales
management seminars and technical development programs, and has established a
professional career ladder development program. Additionally, the Company offers
a tuition reimbursement program for all employees of the firm.

None of the Company's employees are represented by a union. The Company
considers its relationship with employees to be good.

Competition

Nationwide, the environmental industry employs more than one million people,
working at over 100,000 firms, generating revenues in excess of
$181,000,000,000. However, the environmental engineering and consulting market
is becoming highly competitive and requires skilled and experienced
professional, technical, and management personnel. Today, the domestic market
for environmental services can be characterized as flat in revenue and income.
Over the past several years, in an effort to reduce costs and increase volume,
the environmental industry experienced an increase in merger and acquisition
activity, resulting in several mega-environmental firms with revenues greater
than $500,000,000.

Typical projects, especially those in excess of $100,000, are bid on by numerous
firms. The principal competitive factors are client relationships, pricing,
reputation, quality of services, expertise, and local presence. Increasingly,
multiple firms are deemed "technically qualified," resulting on the factors of
price and relationships to determine the winning bid.

EA believes that its favorable competitive factors are its multidisciplinary
capabilities, its reputation for quality of services, its certifications to
provide analytical and consulting services to a broad constituency, and its
geographical dispersion. In each market sector, EA competes with engineering and
consulting firms which are both larger and smaller than the Company, although
management believes no one firm currently dominates a significant portion of any
of the service areas.

Licensing and Certification

The Company's laboratory has been approved/validated to perform analyses for the
Naval Facility Engineering Service Center (NFESC), the Air Force Center for
Environmental Excellence (AFCEE), and the U.S. Army Corps of Engineers (Missouri
River Division). Regulatory authorities frequently will not accept analytical
evidence of compliance unless the analysis has been performed by a laboratory
with relevant certifications such as those described above.

The laboratory is also certified by 41 different states including Maryland, New
Jersey, New York, and California, and maintains certain local permits and
licenses. Additionally, the laboratory has been authorized to do work by the
District of Columbia and 9 states that do not have formal certification
programs. The laboratory has certifications and permits to operate in states and
jurisdictions where the Company performs its services. To support all of these
programs, the laboratory must be periodically audited by these regulatory
agencies and is required to participate in a variety of performance evaluations
such as those conducted by the EPA and U.S. Army Corps of Engineers.

The criteria necessary for obtaining and maintaining laboratory certifications
and permits varies significantly by agency and by state. Generally the criteria
include:

   o  Application for certification/permit
   o  Request and initial review for compliance with comprehensive rules and
      regulations
   o  Periodic verification of compliance through proficiency samples
   o  Periodic onsite audits
   o  Payment of annual fees

Historically, the laboratory has experienced no significant audit problems.
While audits may result in certain "findings," these are usually procedural in
nature and prompt changes or other adjustments to bring the Company into
compliance with the auditor's request. The Company has been able to obtain and

                                        6

maintain its certifications and permits without interruption. However, if the
Company is unable to obtain and maintain such participation and certifications,
the operation of the laboratory and the Company's financial condition may be
adversely affected. Management believes that the Company currently possesses the
licenses or permits necessary to perform its engineering and consulting
services.

Regulatory Matters

Many environmental laws and regulations have been enacted by federal, state, and
local governments in response to growing public concern over activities and
substances deemed to have adverse effects on the environment and on human health
and safety. Historically, compliance with these environmental laws and
regulations by both private and public sector clients has been the primary force
in creating demand for the Company's services. Those laws include:

The Safe Drinking Water Act (SDWA) of 1974 directs the Environmental Protection
Agency to set drinking water standards for community water supply systems in the
United States. In 1996, Congress reauthorized the act, introducing substantive
changes to the regulation and financing of water systems. Those changes include
regulatory improvements with standards based on better science, risk assessment,
and prioritization of efforts, and stronger programs to prevent contamination of
drinking water sources. The act integrates watershed protection planning
programs to control non-point contaminants. A key provision of the reauthorized
act introduces new funding for states and community water systems through a
drinking water state revolving program. Nearly $9,600,000,000 through 2006 is
available for low interest loans.

The reauthorized SDWA will have a strong impact on the Company's state and local
government clients, all of whom are responsible for ensuring the quality and
quantity of their community drinking water supplies.

The Federal Water Pollution Control Act of 1972 (the "Clean Water Act" or CWA)
established a system of standards, permits and enforcement procedures for the
discharge of pollutants from industrial and municipal wastewater sources.

The CWA contains many regulations that impact the Company's industrial, federal,
and state and local clients and contribute to its new and ongoing work
assignments for those clients . Key areas for which regulations have been issued
include industrial wastewater pretreatment, surface water toxics control,
stormwater control, nonpoint source pollution control and compliance with the
National Permit Discharge Elimination System. For example, the surface water
toxics program requires states to identify waters adversely affected by toxics
and propose control strategies for both point and non-point sources. Regulations
governing stormwater permitting and management affect facilities as well as
communities, often requiring storm sewer analysis and design, flood control,
watershed planning, and pollution impacts from point and non-point sources.
Additionally, the evaluation and management of ecological habitats, watersheds
and wetlands, are often included in CWA-driven projects.

The Resource Conservation and Recovery Act of 1976 (RCRA) regulates the
management of existing and newly-generated hazardous waste from the time of
generation through final disposal. Every facility that treats, stores or
disposes of hazardous waste must obtain a RCRA permit, and must comply with
certain operating, financial responsibility and closure requirements. The Act
also regulates solid waste activities from household, commercial, and industrial
generators.



                                        7

<PAGE>



Regulations issued pursuant to RCRA significantly affect the need for
environmental treatment and services in the following areas: municipal solid
waste disposal, land disposal of hazardous waste, remediation of environmental
contamination, and management of leaking underground storage tanks. The EPA is
now promoting a program that encourages RCRA corrective action facilities to
meet performance standards through self-implementing (voluntary) programs. The
Company expects this program will hasten the pace of cleanup action for its
clients.

The Clean Air Act (CAA), which was reauthorized in 1990, established a series of
programs to control airborne emissions from mobile and stationary sources. The
act designated many areas of the U.S. in "nonattainment," requiring them to
establish programs, and prepare and implement State Implementation Plans to
reduce emissions and meet federal ambient air quality standards.

The reauthorized CAA contains a sizeable provision for controlling hazardous air
pollutants and established a schedule for installing control technologies where
needed. The act also required thousands of emission sources to obtain
federally-enforceable permits in order to continue to operate. The Company
assists clients in attaining permits, and works with industrial, state and local
government clients to meet attainment goals from stationary and mobile sources,
the latter, through its Clean Fuel Vehicles group.

The Comprehensive Environmental Response, Compensation and Liability Act of 1980
("Superfund"), along with its amendments and reauthorizations, addresses the
uncontrolled releases from inactive or abandoned hazardous waste sites.
Industrial, federal, and state and local entities are all subject to the
requirements of CERCLA for geologic, hydrologic, engineering, risk, and
environmental evaluations. The Company assists its clients in both the
investigative and engineering aspects of CERCLA work, and in designing,
constructing and monitoring site remediation systems.

Brownfields Initiatives. The exodus of U.S. industry from our inner-city or
other industrial locations during the past thirty years has left behind
thousands of former manufacturing and commercial sites, many of which have been
abandoned because of contamination and associated liability to owners and/or
operators. These sites, known as "brownfields," number more than 500,000
nationwide.

The Clinton Administration introduced the Brownfields Initiative, which was
designed to encourage inner-city economic development and property reuse by
resolving the cleanup and liability issues associated with contaminated
industrial properties. Most states now have targeted efforts and voluntary
cleanup programs under this Initiative. The Company has participated in many
Brownfields projects and expects to continue work in this area in many states
where Brownfields programs are active.

Insurance

The Company maintains a full range of insurance coverage including professional
liability insurance and pollution liability coverage. There can be no assurance
that the Company will not incur liability with respect to the professional
services it renders or that such liability, if incurred, will not have a
material adverse effect upon the Company. However, these insurance policies will
provide limited protection and defense up to their stated amounts.

EA has endeavored to protect itself through contractual indemnification from
clients when possible and by intensifying its existing quality control and
assurance, and health and safety programs. Generally, indemnification is not
available under the Company's government contracts. The Company's quality
control and assurance program includes a control function to establish standards
and procedures for performance and documentation of performance of project
tasks, and an assurance function to audit the

                                        8

<PAGE>



control function and to monitor compliance with procedures and quality
standards. An additional objective of this program has been to establish
practices and procedures to protect EA personnel from hazardous substance
situations. This is accomplished through a company-wide occupational safety and
health monitoring program managed by corporate health and safety professionals.

Equipment

The Company owns substantially all of the analytical, computer, monitoring,
testing and other equipment required to render its various consulting and
testing services. Additionally, the Company leases certain computer, office
furniture, and other equipment. Equipment and various other items which the
Company purchases on behalf of clients are available from several suppliers and
the Company is not dependent on any one supplier.

Environmental and Other Considerations

The Company does not believe that its compliance with federal, state and local
laws and regulations relating to the protection of the environment will have any
material effect on its capital expenditures, earnings, or competitive position.

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

General

The Company's results of operations are significantly affected by the timing of
the award of contracts, the timing of performance on contracts, and the extent
to which the Company's employees are performing billable tasks as opposed to
engaging in preparing contract proposals, bids, and other required non-billable
activities. Results of operations may also be affected to the extent that the
Company chooses not to reduce its professional staff during a period of reduced
demand for its services. Due to these factors, quarterly results of operations
are not necessarily indicative of the results of operations for longer periods.

The Company, in the course of providing its services, routinely subcontracts
such services as drilling, certain laboratory analyses, and other specialized
services. In addition, as described in the "General" section of Item 1, the use
of teaming partners for the performance of services similar to those of the
Company, is included in subcontracts. In accordance with industry practice and
contract terms that generally provide for the recovery of overhead costs, these
costs are passed directly through to clients and are included in total revenue.
Because subcontractor costs and direct charges can change significantly from
project to project, the change in total revenue is not necessarily a true
indication of business trends. Accordingly, the Company considers net revenue,
which is total revenue less subcontractor costs, as its primary measure of
revenue.

Results of Operations

The following table sets forth the percentage relationships of selected items in
the statement of operations to net revenue for the years indicated. It should be
noted that, for historical comparisons, operating costs in past years have been
adjusted to include sales and marketing related costs in sales, general, and
administrative costs. In previous years, these costs were included in direct
salaries and other operating expenses.

Fiscal 1997 Compared to Fiscal 1996

Net revenue during fiscal 1997 decreased to $52,455,100 from $64,353,700. The
decrease was attributable to lower contract volume associated with the
Department of Defense, industrial, and federal non-DOD agency activities.
Additionally, price competition remains intense within the environmental
services industry, further supressing net revenue levels compared to the prior
year.

Direct salaries and other operating costs decreased 13.4% to $50,031,700 from
$57,799,000. As a percentage of net revenue, however, direct salaries and other
operating costs increased to 95.4% from 89.8% a year earlier. This increase was
primarily attributable to realized losses related to certain landfill projects
amounting to approximately $1,400,000 of costs in excess of contract values.
Additionally, lower staff utilization, especially in the second quarter,
attributable to the reduction in available work caused an increase in operating
costs relative to net revenue. In March 1997 the Company announced a major
organizational realignment to reposition itself in the marketplace. In
connection with the restructuring, the Company incurred charges of $3,000,100
during the third quarter related to severance, planned reduction in office
space, the suspension of the implementation of a new project/financial system,
and other related costs. This restructuring included a staff reduction of
approximately 125 employees.

Sales, general and administrative costs increased 6.4% to $7,445,400 in 1997
from $6,997,600 in 1996, or 14.2% and 10.9% of net revenue, respectively. The
increase was due primarily to bonus amounts paid to management as a result of
the Company's exceeding its profit targets for the final five months of the
year. No bonuses were paid in fiscal 1996.

As a result of the above factors, the loss from operations was $8,022,100
compared to a loss from operations of $443,600 in the prior year. Interest
expense, net, decreased slightly to $354,800 from $357,500. A net decrease in
interest expense from lower-than-average borrowings was offset by higher rates
and an interest payment made in connection with a state income tax settlement.

The benefit from income taxes was $2,969,300 for the year ended August 31, 1997,
compared to a benefit from income taxes of $221,000 for the year ended 1996,
representing effective rates of 35% and 28%, respectively. The difference in
effective tax rates between years is largely attributable to increases in
certain permanent differences between financial and income tax reporting, and to
the non-recognition of the future benefits attributable to a foreign loss for
the fiscal year ended 1996. It is the opinion of management that these recorded
benefits are more likely than not to be realized.

The net loss for the twelve months ended August 31, 1997, was $5,407,600, or
10.3% of net revenue, compared to net loss of $580,100, or 0.9% of net revenue
for the prior year.

Fiscal 1996 Compared to Fiscal 1995

Net revenue during fiscal 1996 decreased to $64,353,700 from $72,471,400. The
decrease was primarily attributed to federal regulatory uncertainties and
budgetary delays, partially offset by an increase in private industry revenues.

                                       14

<PAGE>



Direct salaries and other operating costs decreased 3.3% to $57,799,700 from
$59,681,450. As a percentage of net revenue, however, direct salaries and other
operating costs increased to 89.8% from 82.4% a year earlier. This increase was
attributable to unrecoverable costs on certain projects and lower staff
billability related to the reduction in available work. The Company performed
staff reductions to the extent possible while keeping necessary staff
capabilities required throughout the country for both project and business
development purposes. Additionally, more time was devoted by staff to the
development of new business and the completion of proposals in an attempt to
maintain backlog at higher levels during a challenging economic period.

Sales, general, and administrative costs decreased 19.1% to $6,997,600 in 1996
from $8,649,250 in 1995, or 10.9% and 11.9% of net revenue, respectively. The
decrease was due to staff reductions and related overhead expense decreases.

As a result of the above factors, the loss from operations was $443,600 compared
to income from operations of $4,140,700 in the prior year. Interest expense,
net, decreased 16.5% to $357,500 from $428,200. The net decrease in interest
expense is primarily the result of lower interest rates and decreasing long-term
debt principal balances, partially offset by increased borrowings under the
revolving line of credit to fund federal subcontracting payment requirements on
certain projects.

The benefit from income taxes was $221,000 for the year ended August 31, 1996,
compared to a provision for income taxes of $1,485,100, representing effective
rates of 28% and 40%, respectively. The difference in effective tax rates
between years relate primarily to the non-recognition of the future benefits
attributable to a foreign loss and increases to certain permanent differences
between financial and income tax reporting.

The net loss for the twelve months ended August 31, 1996, was $580,100, or 0.9%
of net revenue, compared to net income of $2,227,400, or 3.1% of net revenue for
the prior year.

Fiscal 1995 Compared to Fiscal 1994

Net revenue during fiscal 1995 increased 13.7% to $72,471,400 from $63,748,100.
The increase reflects increased contract volume associated with federal agencies
with which EA holds indefinite deliveryindefinite quantity type contracts.
Additionally, increased use of team partners and subcontractors provided
increased recovery of overhead costs and fees which are reflected in the net
revenue increase.

Direct salaries and other operating expenses increased 13.5% to $59,681,450 from
$52,583,611, and remained relatively constant as a percentage of net revenue at
82.4% and 82.5%, respectively. Salary, general, and administrative costs
increased 10.1% to $8,649,250 from $7,859,289, but decreased as a percent of net
revenue to 11.9% from 12.3%. Management expects the percentage of selling,
general, and administrative expenses to net revenue to further decrease
reflecting a decrease in staff at the end of the fourth quarter.

Interest expense, net, increased 60.2% to $428,200 from $267,300, largely as a
result of increased interest rates and higher average monthly borrowings under
the Company's credit facility.

The provision for income taxes in fiscal 1995 was $1,485,100 compared to
$1,215,300 in fiscal 1994. The effective tax rate for both years was 40%.

For fiscal 1995, net income was $2,227,400, or 3.1% of net revenue, compared to
net income of $1,822,600 or 2.9% of net income for fiscal 1994.

Inflation

Because of its ability to generally pass through increased costs to its clients,
as well as the generally low levels of inflation, the Company believes that
inflation has not had a material impact on its operations.

Liquidity and Capital Resources

Cash and cash equivalents (cash) increased by $1,024,700 in 1997 compared to
decreases of $2,505,300 in 1996 and $174,600 in 1995. The increase in 1997
principally resulted from decreases in accounts receivable and costs and
estimated earnings in excess of billings on uncompleted projects.

The Company's capital expenditures (consisting primarily of purchases of
equipment and leasehold improvements) of approximately $699,000, $1,008,500, and
$1,067,200 in 1997, 1996, and 1995, respectively, have been funded primarily
from cash flows.

The Company entered into a new bank credit arrangement with a regional bank near
the end of the fiscal year consisting of: (i) an $8,500,000 revolving line of
credit secured by receivables; (ii) a $500,000 term loan; and (iii) an equipment
line of credit of $1,500,000. Of the $8,500,000 revolving line of credit,
$2,500,000 is available for acquisitions, joint ventures and licensing
agreements. Borrowings from the revolving line of credit are limited to certain
percentages of accounts receivable and costs and estimated earnings in excess of
billings (up to a maximum of $4,000,000). The interest on all borrowings is
LIBOR +250 , which may be reduced to LIBOR +200 in the third quarter of fiscal
1998 and LIBOR +150 in the first quarter of fiscal 1999 if the Company achieves
certain financial ratios.

At August 31, 1997, the Company had outstanding long-term debt, including the
current portion, of $2,980,000, which represented a decrease of $329,000 from
the August 31, 1996 balance of $3,309,100. The Company had no short-term
borrowings under its line of credit at August 31, 1997 and 1996.

The Company's existing funds, cash from operations, and the available portion of
its $8,500,000 bank line of credit and $1,500,000 equipment line are expected to
be sufficient to meet the Company's present cash needs. The Company also
believes it has the ability to raise capital through placement of debt and will
pursue such options as the need arises to expand facilities, make acquisitions
or acquire equipment in conjunction with a review of the most cost-effective
means for the Company and its stockholders.

While the Company believes that there is sufficient demand for current operating
levels, there can be no assurance that this demand will exist or continue.
Although the Company has the ability to reduce its professional staff in periods
of reduced demand, it may choose not to make full reductions in such periods,
with resulting adverse effects on operations.

          EA ENGINEERING, SCIENCE, AND TECHNOLOGY, INC. & SUBSIDIARIES

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
               FOR THE YEARS ENDED AUGUST 31, 1997, 1996, AND 1995



  Note 1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

  Basis of Presentation--

  The accompanying consolidated financial statements present the accounts of EA
  Engineering, Science, and Technology, Inc. (EA) and its wholly-owned
  subsidiaries, EA International, Inc. and EA Financial, Inc., and its
  wholly-owned subsidiaries, EA Global, Inc. and EA Engineering, Science, and
  Technology de Mexico, S.A. de C.V. During fiscal 1995, EA Remediation
  Technologies, Inc., formerly a wholly-owned subsidiary, was merged into EA.
  The entities are collectively referred to herein as the "Company." All
  significant intercompany transactions have been eliminated in consolidation.

  Revenue Recognition--

  The Company is a multidisciplinary environmental services organization
  providing a wide range of consulting, engineering, remediation, and analytical
  services. These services are generally performed under time and material,
  fixed price, and cost plus fixed fee contracts which vary in length from one
  month to ten years.

  The Company accounts for contract revenues and costs under fixed price
  contracts using the percentage-ofcompletion method. The
  percentage-of-completion is determined using the "cost-to-cost" method for
  each contract cost component. Under this method, direct labor and other
  contract costs incurred to date are compared to periodically revised estimates
  of the total of each contract cost component at contract completion to
  determine the percentage of revenues to be recognized. Revenues from time and
  material and cost plus fixed fee contracts are recognized currently as the
  work is performed. Provision for estimated losses on uncompleted contracts, to
  the full extent of the loss, is made during the period in which the Company
  first becomes aware that a loss on a contract is probable.

  Contract costs and estimated earnings recognized in excess of amounts billed
  are classified as current assets under "costs and estimated earnings in excess
  of billings on uncompleted contracts." Billings in excess of contract costs
  and estimated earnings are classified as current liabilities under "billings
  in excess of costs and estimated earnings on uncompleted contracts."

  Generally, contracts provide for the billing of costs incurred and estimated
  fees on a monthly basis. Amounts included in "costs and estimated earnings in
  excess of billings on uncompleted contracts" in the accompanying financial
  statements will be billed within twelve months of the balance sheet date.

  Major Clients--

  Various agencies of the federal government accounted for approximately 50%,
  53%, and 64% of the Company's net revenue for the years ended August 31, 1997,
  1996, and 1995, respectively. Additionally,

                                       24

<PAGE>



  various agencies of the federal government accounted for approximately 40% and
  48% of the Company's accounts receivable and costs and estimated earnings in
  excess of billings on uncompleted contracts as of August 31, 1997 and 1996,
  respectively.

  Cash and Cash Equivalents--

  Cash equivalents consist of money market instruments with a purchased original
  maturity of three months or less, stated at cost, which approximates market.

  Property and Equipment--

  Property and equipment are depreciated using the straight-line method over
  their estimated useful lives ranging from 3 to 10 years. Leasehold
  improvements are amortized over the shorter of the estimated useful life or
  the term of the lease.

  Segment Information--

  The Company operates within one industry segment, providing a wide range of
  consulting, engineering, remediation, and analytical services.

  Reclassifications--

  Certain prior year balances have been reclassified to conform with current
year presentation.

  Risks and Uncertainties--

  Reliance on major government contracts subjects the Company to risks
  associated with public budgetary restrictions and uncertainties, discrepancies
  between awarded contract amounts and actual revenues, and cancellation at the
  option of the government. The Company attempts to mitigate these risks by
  staffing only to meet reasonably anticipated average workloads, by using
  subcontractors to handle peak workloads, and by obtaining termination benefit
  contract provisions. Cancellation of any of the Company's major government
  contracts, however, could have a material adverse effect on the Company.

  Use of Estimates--

  The preparation of financial statements in accordance with generally accepted
  accounting principles requires management to make estimates and assumptions
  that affect the reported amount of assets, liabilities, revenues and expenses
  in the financial statements and in the disclosures of contingent assets and
  liabilities. While actual results could differ from these estimates,
  management believes that actual results will not be materially different from
  amounts provided in the accompanying consolidated financial statements.

  Supplemental Disclosures of Cash Flow Information--

  Cash paid during the years ended August 31, 1997, 1996, and 1995 for interest,
  was $467,200, $474,200, and $521,700, respectively. Retirements of property
  and equipment for the same periods were $897,200, $2,602,400, and $46,300,
  respectively. The noncash tax benefit attributable to the exercise of non-

                                       25

<PAGE>



  qualified stock options was $24,600, and $650,900 for the years ended August
  31, 1996 and 1995, respectively. There was no benefit for the year ended
  August 31, 1997.

  Accounting for Income Taxes--

  Deferred income taxes are recorded to reflect the tax consequences on future
  years for differences between the tax basis of assets and liabilities and
  their financial reporting amounts.

  Accounting Pronouncements--

  In March 1995, the Financial Accounting Standards Board (FASB) issued SFAS No.
  121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived
  Assets to be Disposed of." This statement requires that long-lived assets and
  certain identifiable intangibles to be held and used by an entity be reviewed
  for impairment whenever events or changes in circumstances indicate that the
  carrying amount of an asset may not be recoverable. This statement is
  effective for fiscal years beginning after December 15, 1995. Management has
  determined that adoption of this Standard has not resulted in any material
  changes to its financial statements.

  In March 1995, the FASB issued Statement No. 123 (SFAS 123), "Accounting for
  Stock-Based Compensation." Companies have the option of adopting the new
  accounting provisions or may elect to provide pro forma disclosures of net
  income and earnings per share as if the accounting had been adopted.
  Management has elected to continue to account for its stock-based compensation
  in accordance with APB Opinion No. 25 and has provided pro forma disclosures
  (see Note 8).

  In February 1997, the FASB issued Statement No. 128 (SFAS 128), "Earnings Per
  Share," which establishes new standards for computing and presenting earnings
  per share. SFAS 128 is effective for financial statements issued for periods
  ending after December 15, 1997, including interim periods. Management has
  determined that the implementation of SFAS 128 would have no impact on the
  Company's earnings per share amounts.

  In February 1997, the FASB issued Statement No. 129 (SFAS 129), "Disclosure of
  Information about Capital Structure," which eliminates the exemption of
  nonpublic entities from certain disclosure requirements of APB Opinion No. 15
  as provided by FASB Statement No. 21. SFAS 129 is effective for periods ending
  after December 15, 1997. Management has determined that the implementation of
  SFAS 129 will have no impact on the Company's financial reporting.

  In June 1997, the FASB issued Statement No. 130 (SFAS 130), "Reporting
  Comprehensive Income," which establishes standards for reporting and display
  of comprehensive income and its components in a full set of general purpose
  financial statements. SFAS 130 is effective for fiscal years beginning after
  December 15, 1997. Management has not yet determined whether the
  implementation of SFAS 130 will have any impact of the Company's financial
  reporting.

  In July 1997, the FASB issued Statement No. 131 (SFAS 131), "Disclosures About
  Segments of an Enterprise and Related Information," which establishes a new
  approach for determining segments within a company and reporting information
  on those segments. SFAS 131 is effective for fiscal years beginning after
  December 15, 1997. Management has not yet determined whether the
  implementation of SFAS 131 will have any impact on the Company's current
  method of disclosing business segment information.

  Note 4.  BANK FINANCING ARRANGEMENTS:

  The Company entered into a new credit arrangement with a regional bank during
  fiscal year 1997 consisting of: (i) an $8,500,000 revolving line of credit
  secured by receivables; (ii) a $500,000 term loan; and (iii) an equipment line
  of credit of $1,500,000. Of the $8,500,000 revolving line of credit,
  $2,500,000 is available for acquisitions, joint ventures and licensing
  agreements. Borrowings under the revolving line of credit are limited to a
  percentage of certain accounts receivable and costs and estimated earnings in
  excess of billings on uncompleted contracts (up to a maximum of $4,000,000).
  The agreement was effective August 22, 1997. During fiscal years 1997, 1996,
  and 1995, the Company was either in compliance or had obtained waivers on all
  covenants related to these and prior arrangements.

  Note 5.  LEASE COMMITMENTS:

  The Company's central office, laboratory facilities, regional offices, and
  certain furniture and equipment are held under operating leases. These leases
  expire at various dates through fiscal 2007, and certain leases call for
  annual proportionate increases due to property taxes and certain other
  operating expenses. Lease expense amounted to $8,030,200, $8,912,300, and
  $8,469,300 for the years ended August 31, 1997, 1996, and 1995, respectively.
  Lease expense included payments of approximately $2,016,500, $2,054,900, and
  $1,985,300 for years ended August 31, 1997, 1996, and 1995, respectively, to
  partnerships consisting of the Chairman of the Board of EA and certain members
  of his family for its central office, and Loveton, Maryland, regional office
  and laboratory facility. These payments include reimbursements of
  approximately $965,000 per year for pass-through taxes and operating expenses
  incurred by the lessor which include local property taxes, janitorial and
  mechanical equipment maintenance, and utility costs related to the operation
  of both office and laboratory leased space. Management of the Company believes
  the terms and conditions of the transactions between the Company and entities
  with which the Chairman is affiliated, are at least as favorable to the
  Company as could have been obtained from third parties and are in the best
  interest of the Company.

  The minimum lease commitments under noncancellable operating leases are as
follows:

  Note 6.  NET INCOME (LOSS) PER SHARE:

  Net income (loss) per share is based on the weighted average number of shares
  of common stock and common stock equivalents outstanding during the period,
  and have been adjusted retroactively to reflect two 3 for 2 stock splits,
  effected in the form of 50% stock dividends wherein, on February 23, 1994 and
  July 5, 1994, 1 additional share of stock was issued for each 2 shares
  outstanding as of the record dates of February 8, 1994 and June 28, 1994,
  respectively. Common stock equivalents are calculated using the treasury stock
  method. All disclosures with regard to the shares of common stock have been
  adjusted to reflect these stock splits.


  Note 7.  PROFIT SHARING:

  EA maintains a defined contribution plan in which all employees who are at
  least 21 years of age and have completed six months of credited service, as
  defined by the plan, are eligible to participate. The plan provides for
  discretionary employer contributions for each fiscal year, in amounts
  determined annually by the Board of Directors. The plan also includes a 401(k)
  provision, allowing for Company matching contributions. For the years ended
  August 31, 1997, 1996, and 1995, matching contributions to the plan made under
  the 401(k) provisions of the plan, were $534,900, $729,200, and $710,400,
  respectively. Certain officers and stockholders of the Company serve as
  trustees to the plan, as appointed by the Board of Directors.


  Note 8.  STOCK OPTION AND EMPLOYEE STOCK PURCHASE PLANS:

  The Company maintains a Stock Option Plan (the Plan), which provides for the
  grant of nonqualified stock options and incentive stock options to certain key
  employees and officers of the Company. The exercise price of an option granted
  under the Plan may not be less than the fair market value of the under lying
  shares of Common Stock on the date of the grant. A total of 580,200 options
  are issued and outstanding as of August 31, 1997 having an average exercise
  price of $2.34. Of the outstanding options, 200,000 were granted to Donald A.
  Deieso on February 26, 1997 when he joined the Company as President and CEO.
  The exercise amount of the 200,000 shares is $2.25, which was equal to the
  market price on the grant date. There are 340,000 options available for
  issuance as of August 31, 1997.

  The Company maintains an Employee Stock Purchase Plan to provide eligible
  employees with the opportunity to purchase shares of the Company's Common
  Stock through voluntary payroll deductions. Under the Plan, eligible employees
  may purchase shares through monthly payroll deductions at 95% of current
  market value at the time of purchase. The Company pays all administrative
  expenses related to employee purchases. A total of 155,400 shares remain
  authorized for distribution under the Plan as of August 31, 1997.

  The Company maintains two Non-Employee Director Stock Option Plans (1993 and
  1995) which provide for the granting of nonqualified stock options to its
  non-employee directors. The exercise price of the 36,000 options, which were
  outstanding as of August 31, 1997 ranged between $2.375 and $6.125, which
  equaled the fair market value at the dates of grant. A total of 41,500 options
  remain reserved for the Director Stock Option Plans as of August 31, 1997.

  The Company accounts for these plans under APB Opinion No. 25, under which no

  Note 9.  COMPANY RESTRUCTURING:

  On March 25, 1997 the Company announced a major organizational realignment to
  reposition itself in the marketplace. In connection with the restructuring,
  the Company incurred charges of $3,000,100 during the third quarter related to
  severance, planned reduction in office space, the suspension of the
  implementation of a new project/financial system, and other related costs.



                                       32

  This restructuring included a staff reduction of approximately 125 employees.

  As of August 31, 1997, the Company had accruals of $880,100 included as other
  current liabilities in the accompanying consolidated balance sheet for costs
  to be incurred in future periods.

  Note 10.  RELATED PARTY TRANSACTIONS

  At the request of its former primary lender and in order to maintain its
  favorable relationship with that lender, the Company in December 1996
  purchased from this lender the secured loans of three EA officers. These
  interest-free demand loans, in the aggregate amount of $301,000, are secured
  by pledges of the Company's common stock.

partitions constructed which separate the Leased Premises from the remaining or
adjacent premises of the Building.

         (b) The Building. Landlord and Tenant acknowledge that the gross
leasable area in the Building is specified in Section 1(a)(4) ("Gross Leasable
Area" or "GLA"). The GLA shall be used hereinafter for purposes of computing
Tenant's proportionate share of certain expenses payable to Landlord as
Additional Rent. Landlord reserves the right to modify the GLA of the Building
from time to time during the Lease Term as a result of construction of new
improvements or the demolition of existing improvements.

         (c) Tenant's Proportionate Share. Tenant's proportionate share of
certain expenses hereinafter made payable to Landlord as additional rent is
specified in Section 1(a)(5). Said computation is based upon the ratio of the
total rentable area in the Leased Premises to the GLA of the Building. The
Proportionate Share shall be modified during the Lease Term in the event that
the GLA of the Building is modified as described in Section 2(b) above.

3.       Term.

         (a) Lease Term. The term of the Lease (sometimes herein called the
"Lease Term") shall commence on the "Rent Commencement Date," January 1, 1997,
and shall continue for a period of nine (9) years from the first day of the
calendar month next following the first day of the Term, unless sooner
terminated as herein provided.

         (b) Acceptance of Leased Premises. Landlord shall deliver, and Tenant
agrees to accept, possession of the Leased Premises in an "as is" condition,
subject, however, to Landlord's performance of its agreed obligation to replace
at no charge to Tenant the carpet in the rear portion of the fourth floor. By
entering into possession, Tenant shall be deemed to have accepted the Leased
Premises, to have acknowledged that the same are in the condition called for
hereunder and to have agreed that the obligations of the Landlord imposed for
the delivery of the Premises have been fully performed. It is expressly
understood and agreed that Landlord has made no representations or warranties
with respect to the Leased Premises.

4.       Rent.

         (a) Minimum Annual Rent. The minimum Annual Rent reserved hereunder
shall be as specified in Section 1(a)(8) which shall be payable by Tenant to the
Landlord during each Lease Year of the Lease Term in twelve (12) equal monthly
installments of Basic Monthly Rent each as specified in Section (a)(9), due in
advance, without notice or demand, and without set-off, deduction or abatement
of any kind, on the first day of every calendar month thereafter during the
Term. Rent shall be paid to Landlord (or its agent) as specified in Section
1(a)(18), or to such other persons or at such other address as Landlord may
designate from time to time.

         (b) Annual Adjustments to Minimum Annual Rent. On the first day of the
second Lease Year, and on the first day of each Lease Year thereafter during the
Lease Term, the Minimum Annual Rent (than in effect) shall be increased by 3
percent (3%).

         (c)    Additional Rent.

             (i) General. Whenever it is provided by the terms of this Lease
that Tenant is required to make any payment to Landlord other than of Minimum
Annual Rent, such payment shall be deemed to be additional rent ("Additional
Rent").

                                        3


<PAGE>




Unless otherwise expressly specified herein, Additional Rent shall be paid by
Tenant with the installment of Base Monthly Rent thereafter falling due.
Additional Rent shall include, but not be limited to:

             (ii) Basic Operating Expenses. Tenant shall pay to Landlord, as
Additional Rent, its Proportionate Share as set forth in Section 1(a)(5) of any
increase in the Basic Operating Expenses incurred by Landlord in the operation
of the Building during any calendar year over the Base Operating Expense Amount
specified in Section 1(a)(13). As used herein, the "Basic Operating Expenses"
shall mean the sum of all costs of operating, policing, managing, maintaining
replacing and repairing the (A) the Building, (B) the personal property used in
conjunction therewith, and (C) the land upon which the Building is situated and
all curbs and sidewalks adjacent to same. Such costs shall include the

redecoration of all common areas and facilities; sales or use taxes on supplies
or services; and all other reasonable maintenance and repair expenses and
supplies which are deducted by Landlord in computing its Federal income tax
liability; the cost of any capital improvements or alterations made by Landlord
to the Building after the Rent commencement Date of the Lease Term, that reduce
total operating charges, or which are required under any governmental law or
regulation that was not applicable to the Building at the time it was
constructed, such cost to be amortized over such reasonable period as Landlord
shall determine, together with interest on the unamortized balance at the rate
actually paid by Landlord on funds borrowed for purposes of constructing said
capital improvements or alterations; the cost of tools and equipment, materials
and uniforms, supplies and sundries reasonably necessary for the operation and
maintenance of the Building; the Building's share of all costs to maintain,

connection with the use or occupancy of the Building, including any and all
license, permit, and inspection fees; "Real Estate Taxes" (as

                                        4


<PAGE>




hereinafter defined); and any other reasonable costs and expenses incurred by
Landlord in owning, maintaining, repairing or operating the Building or Building
Area. The Basic Operating Expenses shall not include: leasing commissions
payable by Landlord; the cost of capital improvements, as determined under sound
accounting principals, except to the extent set forth above; or the costs of
special services or utilities separately charged to individual tenants of the
Building.

             The term "Real Estate Taxes" shall mean all taxes and assessments,
general and special, ordinary and extraordinary, foreseen and unforeseen, now or
hereafter assessed, levied or imposed upon the Building, and the land on which
it is built, whether or not now customary, including, without limitation, all
other government al impositions and levies, front foot benefit charges and
adequate public facility costs and assessments, together with (i) any tax,
assessment, or other imposition in the nature of a real estate tax, (ii) any ad
valorem tax on rent or any tax on income if imposed in lieu of or in addition to
real estate taxes and assessments, and (iii) any taxes and assessments which may
hereafter be substituted for real estate taxes, including by way of illustration
only, any tax, capital levy, assessment, imposition or otherwise (whether a
business rental or other tax) now or hereafter levied upon Landlord on the rents
or income received from the Building or for Tenant's use or occupancy of or
conduct of business at the Leased Premises, or Tenant's improvements to or
furniture, fixtures or equipment in the Leased Premises. "Real Estate Taxes"
shall further mean any advances or escrow deposits paid or made to any taxing
authority or third party such as a lender on account of any of the foregoing.
"Real Estate Taxes" shall also include all costs, including reasonable attorney
fees, incurred by Landlord in contesting the validity or amount, or in attempts
to restrict increases in, any such taxes. The Real Estate Taxes for any calendar
year shall mean the Real Estate Taxes actually paid or due to be paid during
such calendar year, whether such Real Estate Taxes relates to such calendar year
or a fiscal year.

             (iii) Increases in Basic Operating Expenses. For each calendar year
during which any part of the Term falls, Tenant shall pay to Landlord Tenant's
Proportionate Share of the excess, if any, in Basic Operating Expenses for the
Leased Premises for such year (the "Excess Operating Expenses") over the Base
Operating Expense Amount. Such payment shall be prorated for any partial
calendar year during the Term.

             (iv) Electrical Service. Tenant shall reimburse Landlord on a
monthly basis for all electrical service to the Leased Premises (other than the
electrical service necessary for Landlord to provide standard heating and air
conditioning, which shall be included in "Basic Operating Expenses".) Landlord
shall pay the monthly bills for such services and submit copies of those bills
to Tenant for reimbursement, with no markup or management fee, and Tenant agrees
to pay each bill promptly in accordance with its terms.

             (v) Landlord's Enforcement Costs. Additional Rent shall include any
and all expenses incurred by Landlord, including reasonable attorneys' fees, for
the collection of monies due from Tenant and the enforcement of Tenant's
obligations under the provisions of this Lease. When Landlord, at Tenant's
expense, performs an obligation of Tenant pursuant to the terms of this Lease,
the actual out-of-pocket costs and expenses incurred by Landlord in performance
of such obligations shall be Additional Rent.

                                        5

       (d)    Additional Rent Estimates and Adjustments.

              (i) On or before April 30 (or as soon thereafter as practicable)
of each calendar year, Landlord will submit to Tenant a comparative statement of
the actual increases incurred in Basic Operating Expenses for the preceding
calendar year over the Base Operating Expense Amount, setting forth in
reasonable detail: (i) a schedule of Basic Operating Expenses for the preceding
calendar year, and the amount of the Excess Operating Expenses for such
preceding year; (ii) the amount, if any, paid by Tenant to Landlord during the
preceding calendar year on account of the Excess Operating Expenses for such
preceding year; and (iii) the amount due from Tenant on account of the Excess
Operating Expenses for such preceding year, or the amount due from Landlord to
Tenant because of overpayment by Tenant on account of Excess Operating Expenses.
Landlord's comparative statement of Operating Expenses shall also include
Landlord's good faith estimate of Excess Operating Expenses for the then-current
calendar year and an estimated "Monthly Portion of Excess Operating Expenses"
equal to one-twelfth (1/12) of said good faith estimate of Excess Operating
Expenses.

              (ii) Tenant shall pay Landlord, within thirty (30) days of
Tenant's receipt of such statement, as Additional Rent, any amounts due from
Tenant on account of Excess Operating Expenses for the preceding year. Tenant
shall also make payments to Landlord, on account of the Excess Operating
Expenses for the then current calendar year, as follows:

                     (A) On the first day of the first full month following
receipt by Tenant of the Landlord's comparative statement of Basic Operating
Expenses, Tenant shall pay to Landlord an amount equal to the Monthly Portion of
Excess Operating Expenses multiplied by the number of months elapsed in the
current calendar year (including the month in which the payment is made); and

                     (B) Commencing on the first day of the second full month
following receipt by Tenant of Landlord's comparative statement of Basic
Operating Expenses, and continuing until the receipt by Tenant of the next
annual comparative statement, the minimum monthly installments of rent due
hereunder shall be increased by an amount equal to the Monthly Portion of Excess
Operating Expenses.

              (iii) Landlord shall refund any overpayment made by Tenant within
thirty (30) days after Landlord's submission to Tenant of the aforesaid
operating charge statement for such calendar year.

              (iv) Contemporaneously with presentation of Landlord's statement
showing actual figures for the year, Landlord shall furnish to Tenant, in
writing, a detailed statement of Basic Operating Expenses and copies of Real
Estate Tax bills. If it shall be determined that there is an error in Landlord's
statement, Tenant shall be entitled to a credit for any overpayment, or, if
Landlord billed Tenant less than should have been billed to Tenant, Tenant shall
pay such difference to Landlord. Any payment, refund or credit made pursuant to
Section 4(c) or 4(d) shall be made without prejudice to any right of Tenant to
dispute, or of Landlord to correct, any item(s) as billed pursuant to the
provision hereof; provided, however, such right to correct or adjust rental
payments shall terminate at the expiration of two (2) years after the date any
payment shall have become due.

              (v) Tenant's obligation to pay any Additional Rent accruing during
the Lease Term pursuant to this Section shall apply pro rata to the
proportionate part


                                        6


<PAGE>





of the calendar year as to Basic Operating Expenses, in which this Lease begins
or ends, for the portion of each such year during which this Lease is in effect.
Such obligation to make payments of such Additional Rent shall survive the
expiration or sooner termination of the Lease Term, whether or not this Lease is
superseded by a subsequent lease of the Leased Premises or of any other space or
Tenant leaves the Building; any such superseding lease shall not serve to
supersede Tenant's obligation for any such additional rent unless it makes
express reference thereto and recites that such additional rent is abated in
consideration of the superseding lease.

              (vi) If, during the Term of this Lease, there shall be a reduction
or elimination of any particular component of Basic Operating Expenses by reason
of the introduction of a labor-saving device, energy conservation device,
capital improvement or replacement installed by Landlord, the corresponding item
of expense in the Base Operating Expense shall be eliminated or reduced in the
same proportion as the reduction of that item in the Basic Operating Expense for
the purposes of calculating Tenant's share of Excess Operating Expenses.

              (vii) In the event that Landlord shall make a capital expenditure
for an Essential Capital Improvement (as hereinafter defined) during the Term of
this Lease, the annual amortization of such expenditure (determined by dividing
the amount of the expenditure by the useful life of the improvement) plus
interest on the unamortized balance at the rate actually paid by Landlord for
funds borrowed by Landlord to construct or otherwise provide such Essential
Capital Improvement, shall be deemed an Operating Expense for each year of such
useful life. As used herein, an "Essential Capital Improvement" means any of the
following: (A) a labor saving device or other installation, improvement or
replacement which reduces Operating expenses; (B) an installation or improvement
required by reason of any law, ordinance or regulation of any governmental or
quasi-governmental body, which requirement did not exist (or was not applicable
to the Building) on the date of execution of this Lease; or (C) an installation
or improvement which directly enhances the safety of tenants in the Building
generally (as, for example, but without limitation, for fire safety or
security); provided, however, any expense treated as an Essential Capital
Improvement hereunder must, at Tenant's option and expense, be certified by
independent auditors for Landlord as constituting an Essential Capital
Improvement under generally accepted accounting principles.

      (e) Payment of Rent. In the event Minimum Annual Rent or Additional Rent
is not paid within ten (10) days after the same is due, a late charge equal to
five percent (5%) of the delinquent amount shall be assessed as liquidated
damages for the additional administrative charges incurred by Landlord as a
result of such late payment. Tenant also agrees to pay all reasonable attorney
fees incurred by Landlord as a result of Tenant's delinquent payment of rent. No
payment by Tenant or receipt by Landlord of lesser amounts of rent than those
herein stipulated shall be deemed to be other than on account of the earliest
unpaid stipulated rent. No endorsement or statement on any check or any letter
accompanying any check or payment as rent shall be deemed an accord and
satisfaction, and Landlord may accept such check or payment without prejudice to
Landlord's right to recover the balance of such rent or pursue any other remedy
provided in this Lease. If Landlord shall pay any monies, or incur any expenses
in correction of violation of covenants herein set forth, the amount so paid or
incurred shall, at Landlord's option, and on written notice to Tenant, be
considered Additional Rent payable by Tenant with the first installment of
rental thereafter becoming due and payable. If Landlord receives from Tenant two
(2) or more returned or "bounced" checks in any twelve (12)

                                        7


<PAGE>




month period, Landlord may require all future rent be paid by cashier's or
certified check.

5. Security Deposit. Tenant has deposited with Landlord the sum specified in
Section 1(a)(12). Said deposit shall constitute advance rental and shall be held
by Landlord as security for the faithful performance by Tenant of all the terms,
covenants and conditions of this Lease to be kept and performed by Tenant during
the Lease Term. If, at any time during the Lease Term, any payment of Minimum
Annual Rent or Additional Rent herein reserved shall be overdue and unpaid, the
Landlord may, at its option, appropriate and apply any portion of said security
deposit to the payment of any such overdue rent or other sum. Landlord shall
have the unrestricted right (but not the obligation) to apply any part of the
Security Deposit to cure any Default (as described in Section 20 hereof).

      In the event of the failure of Tenant to keep and perform any other items,
covenants and conditions of the Lease to be kept and performed by Tenant, then
Landlord, at its option, may appropriate and apply the entire security deposit,
or so much thereof as may be necessary, to compensate Landlord for loss or
damage sustained or suffered by Landlord due to such breach by Tenant. Should
the entire security deposit, or any portion thereof, be appropriated and applied
by Landlord for the payment of overdue rent, to cure any default, or other sums
due and payable to Landlord by Tenant hereunder, then Tenant shall remit to
Landlord, within ten (10) days of the written demand of Landlord, a sufficient
amount in cash to restore the security deposit to the original sum. Tenant's
failure to do so shall constitute a breach of the Lease. Should Tenant comply
with all of said terms, covenants and conditions of the Lease and promptly pay
all Minimum Annual Rent and Additional Rent herein provided as it falls due,
then the security deposit shall be returned in full, without interest, to Tenant
within thirty (30) days of the Expiration Date or earlier termination of the
Term of this Lease. Tenant shall have no right to direct the application of any
part of the Security Deposit.

      Landlord may deliver the funds deposited hereunder by Tenant to the
purchaser of Landlord's interest in the building and/or the Leased Premises in
the event that such interest is sold, and thereupon Landlord shall be discharged
from any further liability with respect to such security deposit.

6. Improvement of the Leased Premises. Intentionally deleted.

7. Alterations or Improvements by Tenant. Except for the incidental hanging of
pictures, installation of shelves, and other painting and decoration of the
Leased Premises which do not affect the structure of the Leased Premises, Tenant
shall not make any alterations, additions, or improvements, structural or
otherwise (collectively, "Alterations") in the Leased Premises (such as
carpeting, telephone installation, decoration and installation of specialized
equipment), without the prior written consent of Landlord, which consent shall
not be unreasonably withheld. Tenant shall not install any equipment of any
nature whatsoever which may affect the insurance rating of the Building, or
which may necessitate any changes, replacements or additions to the water
system, plumbing system, heating system, air-conditioning system, telephone
system or the electrical system of the Leased Premises, without the prior
written consent of Landlord, which consent shall not be unreasonably withheld.
Tenant shall pay all costs to make such changes, replacements or additions.

      Tenant hereby agrees that all Alterations made in, to, or on the Leased
Premises shall, unless otherwise provided by written agreement, be the property
of Landlord

                                        8


<PAGE>




and shall remain upon and be surrendered with the Leased Premises on the
Expiration Date or other termination of this Lease, unless Landlord shall, prior
to such expiration or termination have given Tenant not less than 15 days prior
written notice to remove the same, in which event Tenant shall at its expense
forthwith remove such Alterations. Any or all wiring and cabling, such as
telephone, computer and data wires installed by Tenant shall be removed by
Tenant at its sole cost, and the Leased Premises shall be restored to their
original condition by the Expiration Date, ordinary wear and tear excepted. All
property permitted or required to be removed by Tenant at the end of the term
remaining in the Leased Premises after Tenant's removal shall be deemed
abandoned and may, at the election of Landlord, either be retained as Landlord's
property or may be removed from the premises by Landlord at Tenant's expense.

8.    Use of Leased Premises.

       (a) Use. Tenant shall use and occupy the Leased Premises for the singular
purpose specified in Section 1(a)(11) and for no other purpose. Tenant shall not
use or permit the Leased Premises to be used for any other purpose or purposes
without the prior written consent of Landlord, which consent may be granted or
withheld in its sole discretion.

      (b) Compliance. Tenant, at its expense, shall comply with the laws, rules
and regulations of any federal, state or municipal authority, or the Maryland
Fire Underwriters Rating Bureau, or with any notice from any public officer
pursuant to law, or with any notice from any insurance company pertaining to
Tenant's occupancy or use of the Leased Premises, whether such notice shall be
served on Landlord or Tenant. In furtherance of the foregoing, and provided
Tenant shall first have obtained Landlord's prior written consent (which Tenant
agrees to promptly request), Tenant shall, at Tenant's sole cost and expense,
make such changes, alterations, renovations or modifications to the Leased
Premises (except for structural repairs) which are necessitated or required by
any such Law.

              (i) Legal. Tenant shall not use or permit the Leased Premises or
any part thereof to be used in violation of any present or future applicable
law, regulation or ordinance, or of the certificate of occupancy issued for the
Building or the Leased Premises, and shall immediately discontinue any use of
the Leased Premises which is declared by any governmental authority having
jurisdiction to be in violation of law or said certificate of occupancy. Tenant
will not use or permit the Leased Premises to be used for any purposes that
interfere with the use and enjoyment of the Building by Landlord or the other
tenants, which will increase the existing rate of insurance on the Building or
which violate the requirements of any insurance company insuring the Building or
its contents, or which, in Landlord's sole discretion, impair the reputation of
the Building. Tenant shall refrain from and discontinue such use immediately
upon receipt of written notice from Landlord.

              (ii) Fire and Safety. Tenant shall not do, or permit anything to
be done in the Leased Premises, or bring, use or keep anything therein, which
will in any way increase the rate of fire insurance on the Building, or
invalidate or conflict with fire insurance policies on the Building, fixtures or
on property kept therein. Tenant agrees that any increases of fire insurance
premiums on the Building or contents caused by the occupancy of Tenant and any
expense or cost incurred in consequence of negligence or the willful action of
Tenant, Tenant's employees, agents, servants, invitee, or licensees shall be
deemed Additional Rent and paid as accrued.

                                        9


<PAGE>




      (c) Environmental Protection. Tenant and Tenant's employees and agents
shall not dispose of any oil, petroleum or chemical liquids or solids, liquid or
gaseous products or any hazardous waste or hazardous substance including,
without limitation, asbestos (hereinafter collectively referred to as "hazardous
waste"), as those terms are used in the Comprehensive Environmental Response,
Compensation and Liability Act of 1980, or in any other federal, state or local
law governing hazardous substances (hereinafter referred to as the "Act"), as
such laws may be amended from time to time at, upon, under or within the Leased
Premises or the Building or the land on which it is built, or into the plumbing
or sewer or water system servicing the Leased Premises or the Building, nor
shall Tenant, its employees or agents cause or permit the discharge, spillage,
uncontrolled loss, seepage or filtration of any hazardous waste at, upon, under
or within the Leased Premises or the Building or the land or into the plumbing
or sewer or water system servicing the same. Tenant shall comply in all respects
with the requirements of the Act and related regulations, and shall notify
Landlord immediately in the event of its discovery of any hazardous waste at,
upon, under or within the Leased Premises or the Building or the land.

      (d) Indemnification. Tenant shall indemnify Landlord against all costs,
expenses, liabilities, losses, damages, injunctions, suits, fines, penalties,
claims, and demands, including reasonable attorneys' fees, arising out of any
violation of or default in the covenants of this Section 8. The provisions of
Sections 8(b) and (c) and this Section 8(d) shall survive the expiration of the
Lease Term.

      (e) Moving and Deliveries. No freight, furniture, heavy machinery, heavy
equipment, including computer equipment or other bulky matter or fixtures of any
description shall be transferred into or out of the Building or carried in the
elevators, without Landlord's prior written consent and approval. In obtaining
the Landlord's approval as required under this paragraph, Tenant agrees to
provide Landlord with all technical specifications concerning the equipment and
machinery and to pay the costs of any and all structural changes which in the
sole discretion of the Landlord are required to be made in order to safely and
efficiently accommodate such equipment or machinery. If such machinery or
equipment requires special handling, Tenant agrees to employ only persons
holding the proper licences to do said work, and that all work in connection
therewith shall comply with any applicable Federal, State, County or other
governing laws, rules or regulations. Tenant shall promptly remove from the
public areas within or adjacent to the Building any of Tenant's property
delivered or deposited there, and shall be liable for any damage to the Building
or the Leased Premises caused by its moving and deliveries.

      (f) Excessive Floor Load. Landlord shall have the right to prescribe the
weight and method of installation and position of safes or other heavy fixtures
or equipment. Tenant will not, without Landlord's prior written approval,
install in the Leased Premises any fixtures, equipment or machinery that will
place a load upon the floor exceeding the designed floor load capacity. Tenant
shall be liable for all damage done to the Building by installing or removing a
safe or any other article of Tenant's office equipment, or due to its being in
the Leased Premises. Landlord shall repair any such damage at Tenant's expense,
and Tenant shall pay the cost therefor to Landlord upon demand, as Additional
Rent.

9. Taxes on Tenant's Property. Tenant shall be liable for, and shall pay at
least ten (10) days before delinquency, all taxes levied against any personal
property or trade fixtures placed by Tenant in or about the Leased Premises. If
any such taxes

                                       10


<PAGE>




on Tenant's personal property or trade fixtures are levied against Landlord or
Landlord's property, or if the assessed value of the Leased Premises is
increased by the inclusion therein of a value placed upon such personal property
or trade fixtures of Tenant, and if Landlord, after written notice to Tenant,
pays the taxes based upon such increased assessments (which Landlord shall have
the right to do regardless of the validity thereof, but under protest if
requested by Tenant), Tenant shall upon demand repay as Additional Rent to
Landlord a sum equal to the taxes levied against Landlord or the portion of such
taxes resulting from such increase in the assessment; provided that, in any such
event, Tenant shall have the right, at Tenant's sole cost and expense, to bring
suit to recover the amount of any such taxes so paid under protest, and any
amount so recovered shall belong to Tenant.

10. Rules and Regulations. Tenant covenants on behalf of itself, its employees,
agents, licensees and invitees to comply with the rules and regulations set
forth in Exhibit B, which is attached hereto and made a part hereof (the "Rules
and Regulations"). Landlord shall have the right, in its sole discretion, to
make reasonable additions and amendments to the Rules and Regulations from time
to time and Tenant covenants that Tenant, its employees, agents, licensees and
invitees will comply with additions and amendments to the Rules and Regulations
upon Landlord's provision to Tenant of a written copy of the same. Any
unremedied default by Tenant, or any other party set forth above, of any of the
material provisions of the Rules and Regulations as set forth in Exhibit B, or
as amended from time to time, shall be considered to be a default under the
terms of this Lease. Nothing contained in this Lease shall be construed to
impose upon Landlord any duty or obligation to enforce the Rules and
Regulations, or any amendments or additions thereto, against any other tenant.
Landlord shall have no liability to Tenant or any other party for violations of
the Rules and Regulations by any party whatsoever. If there is any inconsistency
between this Lease and the Rules and Regulations, the Lease shall govern.

11.   Utilities and Services.

       (a) Building Standard Services and Utilities. As long as Tenant is not in
default under any of the covenants of this Lease, Landlord shall, if and insofar
as existing facilities permit, furnish sufficient electric current for routine
and normal requirements for lighting and typical office equipment and machinery,
such as typewriters, calculators, personal computers, small copiers and similar
items, subject to the limitations of Section 11(b). Landlord shall furnish hot
and cold water for lavatory and drinking purposes, lavatory supplies, and
Building standard fluorescent tube replacements and nightly cleaning and
janitorial services Monday through Friday. Landlord further agrees to furnish
heating and cooling during the appropriate seasons of the year, during the
Standard Building Operating Hours and on the days set forth in Section l(a)(15),
exclusive of the Building Holidays specified in Section l(a)(16), with holidays
falling on Saturday observed both on said day and on the preceding Friday, and
holidays falling on Sunday observed on the following Monday.

      (b) Overtime Services. Landlord shall be under no obligation to furnish
electric power at any hours other than normal business hours, or for the
operation of any other electrical equipment or appliance, unless arrangements
for such after-hours operations, and for the installation of such electrical
equipment or appliance, shall have been made pursuant to terms and conditions
acceptable to Landlord and embodied in a separate written agreement between
Landlord and Tenant. In the event that Tenant uses electrical services in excess
of that required for normal office use or during periods other than normal
business hours or both, then

                                       11


<PAGE>




such excess services shall be supplied at the expense of the Tenant, pursuant to
terms, conditions and costs established by the Landlord in its sole discretion.
Should Tenant require heating and cooling services beyond the hours stipulated
in Section 11(a), Landlord will furnish such additional service at the
then-prevailing hourly rate, as established by Landlord from time to time,
provided that Tenant gives Landlord no less than twenty-four (24) hours advance
written notice of the need therefor.

      (c) Interruption or Reduction of Service. In no event shall Landlord be
liable to Tenant for any interruption or failure in the supply of any utilities
to the Leased Premises and the Building. Landlord reserves the right to
interrupt service of the heat, plumbing, air conditioning, cooling, electric,
and sewer and water systems, when necessary, by reason of accident, or of
repairs, alterations or improvements which in the judgment of Landlord are
desirable or necessary to be made, until such repairs, alterations or
improvements shall have been completed; and Landlord shall have no
responsibility or liability for failure to supply heat, plumbing, air
conditioning, cooling, electric, and sewer and water service, or other service
or act for the benefit of Tenant, when prevented from so doing by strikes,
accidents or by any other causes beyond Landlord's reasonable control, or by
orders or regulations of any federal, state, county, or municipal authority, or
by any failure to receive suitable fuel supply, or inability despite exercise of
reasonable diligence to obtain the regularly-used fuel or other suitable
substitute; and Tenant agrees that Tenant shall have no claim for damages nor
shall there be any abatement of Base Annual Rent in the event that any of said
systems or service shall be discontinued or shall fail to function for any
reason. If any public utility supplying any utility to the Building, or any law,
order or regulation of any federal, state, county or municipal authority
requires that Landlord or Tenant must reduce or maintain a certain level of
consumption of electricity or any other utility or interior temperature for the
Leased Premises or the Building, which affects the normal business hours or the
provision of any utility the Leased Premises or the Building, Landlord and
Tenant shall each adhere to and abide by such requirement without any reduction
in rent or in any of Tenant's other obligations hereunder. Landlord's obligation
to supply heat and air conditioning are subject to applicable laws and
regulations as to energy conservation and other restrictions.

       (d)    Excessive Electrical Usage.

              (i) Tenant will not install or operate in the Leased Premises any
heavy duty electrical equipment or machinery, without obtaining the prior
written consent of Landlord, which consent shall not be unreasonably withheld.
Landlord may require, as a condition of its consent to the installation of such
equipment or machinery, payment by Tenant, as Additional Rent, for such excess
consumption of electricity as may be occasioned by the operation of said
equipment or machinery. Landlord may make periodic inspections of the Leased
Premises at reasonable times to determine that Tenant's electrically operated
equipment and machinery complies with the provisions of this Section and Section
11(e).

              (ii) Landlord shall have the right to require that one or more
separate meters or submeters be installed to record the consumption or use of
electricity, or to cause a reputable independent electrical engineer to survey
and determine the quantity of electricity consumed by such excessive use. The
cost of any such survey or meters and of installation, maintenance and repair
thereof shall be paid by Tenant. Tenant agrees to pay Landlord (or the utility
company, if direct service is provided by the utility company), promptly upon
demand therefor, for all such electricity consumption as shown by said meters,
or a flat monthly charge determined

                                       12


<PAGE>




by the survey, as applicable, at the rates charged for such service by the local
public utility company.

      (e) Excessive Heat Generation. Landlord shall not be liable for its
failure to maintain comfortable atmospheric conditions in all or any portion of
the Leased Premises, due to heat generated by any equipment or machinery
installed by Tenant (with or without Landlord's consent) that exceeds
generally-accepted engineering design practices for normal office purposes. If
Tenant desires additional cooling to offset excessive heat generated by such
equipment or machinery, Tenant shall pay for auxiliary cooling equipment and its
operating costs, including, without limitation, electricity, gas, oil and water,
or for excess electrical consumption by the existing cooling system, as
appropriate.

(f) Security. Any security measures that Landlord may undertake are for
protection of the Building only and shall not be relied upon by Tenant to
protect Tenant, its property, its employees and/or their property.

12. Landlord's Right of Entry. Landlord, its agents, employees and contractors
shall have the right to enter the Leased Premises at all reasonable times,
including emergencies determined by Landlord, (a) to make inspections or to make
repairs, replacements and improvements to Leased Premises or other premises as
Landlord may deem necessary or reasonably desirable to the Premises or to any
other portion of the Building or which Landlord may elect to perform; (b) to
perform nightly cleaning of the Leased Premises; (c) to exhibit the Leased
Premises to prospective purchasers at any reasonable time, or to prospective
tenants during the last one hundred and eighty (180) days of the Lease Term; and
(d) for any purpose whatsoever relating to the safety, protection or
preservation of the Building. Such entry by Landlord shall be, whenever
reasonably possible, during normally business hours, except in cases of
emergency. Landlord shall use reasonable best efforts to minimize interference
to Tenant's business when making repairs, but, unless otherwise agreed with
Tenant, Landlord shall not be required to perform the repairs at any time other
than during normal working hours. The right and authority hereby reserved do not
impose, no does the Landlord assume by reason thereof, any responsibility or
liability whatsoever for the care, maintenance or supervision of the Leased
Premises or any pipes, fixtures, appliances or appurtenances therein contained
or therewith in any manner connected.

13.   Maintenance and Repairs.

       (a) Landlord Responsibilities. Landlord shall make structural repairs to
the Leased Premises necessary for safety and tenantability, and shall maintain
and repair all Building equipment serving the Leased Premises and all exterior
plate glass in the Leased Premises, and the cost of all such repairs or
maintenance shall be included in Basic Operating Expenses. Tenant waives the
right to make repairs at Landlord's expense under any law, statute or ordinance
now or hereafter in effect. Landlord reserves the right at any time and from
time to time, as often as Landlord deems desirable, without the same
constituting an actual or constructive eviction and without incurring any
liability to Tenant or otherwise affecting Tenant's obligations under this
Lease, to make changes, alterations, additions, improvements, repairs,
relocations or replacements in or to the Building and the fixtures and equipment
thereof. Landlord reserves the right from time to time to install, use,
maintain, repair and replace pipes, ducts, conduits, wires and appurtenant
meters and equipment for service to other parts of the Building, above the
ceiling surfaces, below the floor surfaces, within the walls and in the central
core areas, and to relocate any pipes, ducts, conduits wires and appurtenant
meters and

                                       13


<PAGE>




equipment included in the Leased Premises which are located in the Leased
Premises or located elsewhere outside the Leased Premises. Landlord shall use
reasonable efforts not to disturb Tenant's business operations when making
repairs to the Leased Premises or the Building. Nothing contained herein shall
be deemed to relieve Tenant of any duty, obligation or liability with respect to
making any repair, replacement or improvement or complying with any law, order
or requirement of any government or other authority and nothing contained herein
shall be deemed or construed to impose upon Landlord any obligation,
responsibility or liability whatsoever, for the care, supervision or repair of
the Building, or any part thereof, other than as expressly provided in this
Lease.

      (b) Tenant Responsibilities. Tenant will keep the Leased Premises and the
fixtures and equipment therein in good order and condition, will take good care
thereof and will suffer no waste or damage thereto. Tenant will promptly repair
at its own expense any damage to the Leased Premises caused by bringing into the
premises any property for Tenant's use or by the installation or removal of such
property, regardless of fault or by who such damage shall be caused, unless
caused by Landlord, its agents, employees or contractors; and, in default of
such repairs by Tenant, Landlord shall make the same and Tenant agrees to pay
the costs thereof to Landlord promptly upon Landlord's demand therefor. At the
expiration or other termination of the Lease Term, Tenant will surrender the
Leased Premises broom clean and in the same order and condition in which they
were on the Rent Commencement Date, ordinary wear and tear excepted. All repairs
and maintenance required to be performed by Tenant shall be made or performed
immediately upon the occurrence of the necessity therefor, and shall be made or
performed in a first class manner, using first class materials, by a contractor
approved by Landlord and bonded unless waived by Landlord, and shall be made or
performed in accordance with (i) all laws and all applicable governmental codes
and requirements, and (ii) insurance requirements. Maintenance and repair of
equipment such as kitchen fixtures, auxiliary air-conditioning equipment,
private bathroom fixtures and any other type of special equipment, together with
related plumbing or electrical services, whether installed by Tenant or by
Landlord on behalf of Tenant, shall be the sole responsibility of Tenant, and
Landlord shall have no obligation in connection therewith. If Tenant refuses or
neglects to promptly commence and complete repairs or maintenance necessary to
satisfy the provisions of this Section, the Landlord may, but shall not be
required to, make and complete said repairs or maintenance and Tenant shall pay
the cost therefor (including overhead) to Landlord upon demand, as Additional
Rent.

14.   Common Areas.

       (a) Common Areas Defined. In this Lease, "common areas" means all areas,
facilities and improvements provided, from time to time, in the Building for the
mutual convenience and use of tenants or other occupants of the Building, their
respective agents, employees, and invitees and shall include, if provided, but
shall not be limited to, the lobbies and hallways, the public restrooms, the
parking areas and facilities, access roads, driveways, retaining walls,
sidewalks, walkways, landscaped areas, and exterior lighting facilities.

      (b) Landlord's Control. Landlord shall, as between Landlord and Tenant, at
all times during the term of the Lease have the sole and exclusive control,
management and direction of the common areas, and may at any time and from time
to time during the term exclude and restrain any person from use or occupancy
thereof, excepting, however, Tenant and other tenants of Landlord and bona fide
invitee of either who make use of said areas in accordance with the rules and
regulations established by

                                       14


<PAGE>




Landlord from time to time with respect thereto. The rights of Tenant in and to
the common areas shall at all times be subject to the rights of others to use
the same in common with Tenant, and it shall be the duty of Tenant to keep all
of said areas free and clear of any obstructions created or permitted by Tenant
or resulting from Tenant's operation. Landlord may at any time and from time to
time close all or any portion of the common areas to make repairs or changes or
to such extent as may, in the opinion of Landlord, be necessary to prevent a
dedication thereof or the accrual of any rights to any person or to the public
therein, to close temporarily any or all portions of the said areas to
discourage noncustomer parking, and to do and perform such other acts in and to
said areas as, in the exercise of good business judgment, Landlord shall
determine to be advisable with a view to the improvement of the convenience and
use thereof by tenants, their employees, agents, and invites.

      (c) Changes and Additions to the Building, Additional Construction.
Landlord hereby reserves the right at any time to make alterations or additions
to the Building, as well as in or to the street entrances, halls, passages,
stairways and other common facilities thereof. Tenant agrees that Landlord shall
at all times have the right and privilege of determining the nature and extent
of the common areas, and of making such changes, rearrangements, additions or
reductions therein and thereto from time to time which in its opinion are deemed
to be desirable and for the best interest of all persons using the common areas
or which are as a result of any federal, state or local environmental protection
or other law, rule, regulation, guideline or order. The purpose of the floor
plan attached hereto as Exhibit A is to show the approximate locational
relationship of the Leased Premises to other units in the Building and the
common areas as of the Rent Commencement Date. Nothing described in Exhibit A
shall limit or prevent Landlord from effecting any change or alteration to the
Building or the land upon which it is built as described in this paragraph.

      (d) Parking. Tenant shall have the right to utilize the Building's parking
facilities on a nonexclusive basis with other tenants of the Building, upon such
reasonable terms and conditions as may from time to time be established by
Landlord. Landlord reserves the right in its absolute discretion to determine
whether the parking facilities are becoming crowded and to allocate and assign
parking spaces among Tenant and the other tenants. Tenant shall not use parking
areas for the overnight storage of vehicles, other than Tenant-owned corporate
vehicles which Landlord and Tenant have previously agreed will be regularly
parked overnight at the Building. It is understood and agreed that Landlord
assumes no responsibility, and shall not be held liable, for any damage or loss
to any automobiles parked in the parking facilities or to any personal property
located therein, or for any injury sustained by any person in or about the
parking facilities.

15.   Surrender and Inspection.

      (a) Surrender. Upon the Expiration Date or other termination of the term
of this Lease, Tenant shall quit and surrender the Leased Premises to the
Landlord in as good order and condition as when received, ordinary wear and tear
excepted, and Tenant shall remove all of its property from the Leased Premises
by the Expiration Date or other termination of this Lease, all to the reasonable
satisfaction of the Landlord. Tenant's obligation to observe or perform this
covenant shall survive the expiration or other termination of this Lease.

      (b) Inspection. Tenant shall have the right to be present at time of final
inspection of the Leased Premises to determine if any damages were done thereto,
if Tenant notifies Landlord by certified mail of its intention to move, date of
moving

                                       15


<PAGE>




and new address. The notice of Tenant's desire to be present at the final
inspection of the Leased Premises shall be given at least fifteen (15) days
prior to the date of moving. Upon receipt of such notice, Landlord shall notify
Tenant of time and date when the Leased Premises are to be inspected. The
inspection shall occur within five (5) days before or five (5) days after
Tenant's date of moving, said inspection date to be designated by Landlord.
Tenant shall be deemed to have been advised of its rights under this paragraph
by execution of this Lease.

      (c) Fixtures and Personal Property Remaining. If Tenant does not remove
Tenant's furniture, equipment, machinery, trade fixtures, floor coverings and
all other items of personal property of every kind and description from the
Leased Premises prior to the Expiration Date, then Tenant shall be conclusively
presumed to have conveyed the same to Landlord under this Lease as a bill of
sale without further payment or credit by Landlord to Tenant.

16. Tenant Holding Over. If Tenant holds possession of the Leased Premises after
the Expiration Date or other termination of this Lease, Landlord shall have the
option, exercisable in writing within thirty (30) days after the date of
termination of aforesaid, to treat Tenant as a trespasser, or as a tenant by the
month. If the Landlord fails to make such election then the Tenant shall be
deemed a tenant by the month, commencing with the first day after the
termination of the Lease at one hundred and fifty percent (150%) the Basic
Monthly Rent paid during the last month of the Term, and upon all the other
terms of this Lease, including the provisions of this paragraph. Said holdover
term shall terminate upon thirty (30) days notice from one party to the other.
Nothing contained herein shall be construed within said thirty (30) days after
the date of Lease termination as aforesaid as a consent by Landlord to the
occupancy or possession of the Leased Premises by Tenant after the termination
of the Lease, and Landlord, upon said termination, if Landlord elects to treat
Tenant as a trespasser, shall be entitled to the benefit of all public general
or public laws relating to the speedy recovery of the possession of land and
tenements held over by Tenant, whether now or hereafter in force and effect. If
Tenant fails to surrender the Leased Premises upon the expiration or other
termination of this Lease despite demand to do so by Landlord, Tenant shall
indemnify and hold Landlord harmless from all injury, loss, claims, expenses and
liability, including without limitation, any claim made by any succeeding tenant
and any attorneys' fees, founded on or resulting from such failure to surrender.

17. Covenant Against Assignment and Subletting. Tenant shall not assign,
mortgage or encumber this Lease, or any right hereunder, nor sublet the Leased
Premises or any part thereof, nor permit the Leased Premises to be used by
others without the prior written consent of Landlord, which consent shall not be
unreasonably withheld. Notwithstanding the foregoing, however, Tenant may sublet
this lease to an affiliate, parent or subsidiary of Tenant without Landlord's
consent. If Tenant, or any Guarantor, is a corporation, unincorporated
association or partnership, then the transfer, assignment or hypothecation of
any stock or interest in such corporation, association or partnership so as to
result in a change in the control thereof by the person, persons or entities
owning a controlling interest therein as of the date of this Lease, without the
prior written consent of Landlord as described above, shall be deemed an
assignment made in breach of this covenant. Landlord's consent in any specific
instance to any assignment, mortgage, encumbrance, subletting or use of the
Leased Premises and its collection and acceptance of rent from any such approved
assignee, subtenant or other occupant shall neither constitute a waiver of the
provisions of this paragraph, nor be construed as permission for any subsequent
assignment, mortgage, encumbrance, subletting or use without compliance with
this paragraph. Without the prior written consent of Landlord, this Lease and
the

                                       16


<PAGE>




interest of Tenant, or any assignee of Tenant, shall not pass by operation of
law, nor shall it be subject to garnishment or sale under execution in any suit
or proceeding which may be brought against or by Tenant, or any assignee of
Tenant. No permitted assignment or sublease or collection of rent from an
approved assignee or subtenant shall relieve Tenant of its obligations
hereunder. Landlord shall have the right at any time to assign this Lease, in
whole or in part, to any third party.

18.   Bankruptcy.

       (a) The following shall be Events of Bankruptcy under this Lease: (1)
Tenant's or any guarantor of Tenant's obligations under this Lease ("Tenant's
Guarantor") becoming insolvent, as that term is defined in Title 11 of the
United States Code (the "Bankruptcy Code"), or under the insolvency laws of any
state, district, commonwealth or territory of the United States (the "Insolvency
Laws"); (2) the appointment of a receiver or custodian for any or all of
Tenant's or Tenant's Guarantor property or assets, or the institution of a
foreclosure action upon any of Tenant's or Tenant's Guarantor's real or personal
property; (3) the filing of a voluntary petition under the provisions of the
Bankruptcy Code or Insolvency Laws; (4) the filing of an involuntary petition
against Tenant or Tenant's Guarantor as the subject debtor under the Bankruptcy
Code or Insolvency Laws, which either (A) is not dismissed within thirty(30)
days of filing, or (B) results in the issuance of an order for relief against
the debtor; or (5) Tenant's or Tenant's Guarantor's making or consenting to an
assignment for the benefit of creditors or a common law composition of
creditors; or (6) if a corporate reorganization of Tenant or an agent with its
creditors shall be approved by a court under the Federal Bankruptcy Act.

      (b) Upon occurrence of an Event of Bankruptcy, Tenant shall be deemed to
have breached a material covenant of this Lease and Landlord shall have all
rights and remedies available to Landlord pursuant to Section 20; provided,
however, that while a case in which Tenant is the subject debtor under the
Bankruptcy Code is pending, Landlord shall not exercise its rights and remedies
pursuant to Section 20 so long as (1) the Bankruptcy Code prohibits the exercise
of such rights and remedies, and (2) Tenant or its Trustee in Bankruptcy
(hereinafter referred to as "Trustee") (i) cures all defaults under this Lease,
(ii) compensates Landlord for monetary damages incurred as a result of such
defaults, (iii) provides adequate assurance of future performance on the part of
Tenant as debtor in possession or on the part of the assignee tenant, and (iv)
complies with all other requirements of the Bankruptcy Code.

19. Default. Each of the following shall be deemed a default by Tenant and a
breach of this Lease:

      (a)     An Event of Bankruptcy as defined in Section 18;

      (b) An assignment or encumbrance of Tenant's interest in this Lease or the
Leased Premises or a subletting of any part of the Leased Premises in violation
of Section 17;

      (c)     The suspension of business by Tenant;

      (d)     The filing of a tax lien against any property of Tenant;

      (e) Discontinuance by Tenant of the conduct of its business in the Leased
Premises, or an abandonment or vacation of the Leased Premises by Tenant for a
period of sixty (60) days or more;

                                       17


<PAGE>




      (f) A failure by Tenant to pay Minimum Annual Rent or Additional Rent when
due, where such failure continues for ten (10) days after notice thereof from
Landlord, provided, however, that Landlord need provide such notice no more than
three (3) times in any twelve (12) month period, and the fourth such default in
a twelve month period shall be deemed a default by Tenant without such notice
from Landlord;

      (g) A failure by Tenant to observe and perform any other term, covenant,
agreement or condition of this Lease to be observed or performed by Tenant,
where such failure continues for ten (10) business days after notice thereof
from Landlord, provided, however, that if the nature of the default is such that
the same cannot be reasonably be cured within the ten (10) business day period
allowed, Tenant shall not be deemed to be in default if Tenant shall, within
such ten (10) business day period, commence to cure and there after diligently
prosecute the same to completion. Nonetheless, Tenant will be deemed to be in
default if the same default is not cured within sixty (60) days after that
reasonable effort commences. Landlord shall not, however, be required to give
such notice if Tenant's failure to perform constitutes a noncurable breach of
this Lease. The notice required by this Paragraph is intended to satisfy any and
all notice requirements imposed by law on Landlord and is not in addition to any
such requirement;

      (h) Any material misrepresentation by Tenant to Landlord in connection
with the negotiation or execution of this Lease;

      (i) A default by Tenant under any other lease or sublease for any other
space in the Building, which has resulted in the termination of said lease;

      (j) Failure by any surety or guarantor of this Lease to comply with all
the provisions of the suretyship or guaranty agreement; or

      (k) The merger of any corporate surety or corporate guarantor of this
Lease with another entity, or the liquidation or dissolution of such surety or
guarantor or the change of control of such surety or guarantor caused by the
transfer of stock of such surety or guarantor, except by reason of the death of
any shareholder thereof.

20. Landlord's Rights Upon Tenant's Default. Upon default by Tenant of any of
the terms or covenants of this Lease, then in addition to any other remedies
available to Landlord herein at law or in equity, Landlord shall be entitled to
remedy such default as follows:

      (a) Re-Entry. Landlord shall have the right, immediately or at any time
thereafter, without further notice to Tenant (unless otherwise provided herein),
to enter the Leased Premises (breaking open locked doors, if necessary, and
using as much reasonable force as necessary to effect the manner thereof),
without terminating this Lease or being guilty of trespass, and do any and all
acts as Landlord may deem necessary, proper or convenient to cure such default,
for the account and at the expense of Tenant, and Tenant agrees to pay to
Landlord as Additional Rent all damage and/or expense incurred by Landlord in so
doing, including interest at the Penalty Rate, from the due date until the date
payment is received by Landlord. Landlord shall not be liable for any loss,
injury or damage resulting in any way from such action by Landlord.

      (b) Termination. Landlord shall have the right to terminate this Lease and
Tenant's right to possession of the Leased Premises and, with or without legal
process, take possession of the Leased Premises and remove Tenant, any occupant
and

                                       18


<PAGE>




any property therefrom, using such force as may be necessary, without being
guilty of trespass and without relinquishing any rights of Landlord against
Tenant. Landlord shall be entitled to recover damages from Tenant in an amount
equal to the amount herein covenanted to be paid as Minimum Annual Rent during
the remainder of the Lease Term, said Minimum Annual Rent and Additional Rent
for the full term then remaining having been fully accelerated at the option of
Landlord, together with (i) all expenses of any proceedings (including, but not
limited to, legal expenses and reasonable attorney's fees) which may be
necessary in order for Landlord to recover possession of the Leased Premises,
(ii) the expenses of the re-renting of the Leased Premises (including, but not
limited to, any commissions paid to any real estate agent, advertising expense
and the costs of such alterations, repairs, replacements and decoration or
re-decoration as Landlord, in its sole judgment, considers advisable and
necessary for the purpose of re-renting the Leased Premises), and (iii) interest
computed at the Penalty Rate from the due date until paid; provided, however,
that there shall be credited against the amount of such damages all amounts
received by Landlord from such re-renting of the Leased Premises and such
amounts shall be refunded to Tenant.

      Landlord shall use its best efforts to re-rent the Premises, but Landlord
has no obligation to favor the Leased Premises over any other space available
for lease in the Building, and Landlord shall in no event be liable in any way
whatsoever for failure to re-rent the Leased Premises or, in the event that the
Leased Premises are re-rented, for failure to collect the rent thereof under
such re-renting. No act or thing done by Landlord shall be deemed to be an
acceptance of a surrender of the Leased Premises, unless Landlord shall execute
a written agreement of surrender with Tenant. Tenant's liability hereunder shall
not be terminated by the execution of a new lease of the Leased Premises by
Landlord. In the event Landlord does not exercise its option to accelerate the
payment of Minimum Annual Rent and Additional Rent as provided hereinabove, then
Tenant agrees to pay to Landlord, upon demand, the amount of damages herein
provided after the amount of such damages for any month shall have been
ascertained; provided, however, that any expenses incurred by Landlord shall be
deemed to be a part of the damages for the month in which they were incurred.
Separate actions may be maintained each month or at other times by Landlord
against Tenant to recover the damages then due, without waiting until the end of
the term of this Lease to determine the aggregate amount of such damages. Tenant
hereby expressly waives any and all rights of redemption granted by or under any
present or future laws in the event of Tenant being evicted or being
dispossessed for any cause, or in the event of Landlord obtaining possession of
the Leased Premises by reason of the violation by Tenant of any of the covenants
and conditions of this Lease.

      (c) Distress. Upon any default by Tenant in the payment of Minimum Annual
Rent or Additional Rent, Landlord shall have the right, without notice, fifteen
(l5) days after payment of such sum was due, to institute an action of distress
therefor, and, upon distress, in Landlord's discretion, this tenancy shall
terminate. In the event of such termination, the provisions of Section 20(b)
shall be applicable.

      (d) Lien for Rent. Upon any default by Tenant in the payment of Minimum
Annual Rent or Additional Rent, Landlord shall have a lien upon the property of
Tenant in the Leased Premises for the amount of any unpaid Minimum Annual Rent
or Additional Rent. In such event, Tenant shall not remove any of Tenant's
property from the Leased Premises except with the prior written consent of
Landlord, and Landlord shall have the right and privilege, at its option, to
take possession of all

                                       19


<PAGE>




property of Tenant in the Leased Premises, to store the same on the Leased
Premises, or to remove it and store it in such place as may be selected by
Landlord, at Tenant's risk and expense.

      (e) No Future Lease Rights. If at any time during the term of this Lease
Tenant has been in default beyond Tenant's right to cure period, then,
regardless of whether Tenant is in default at the time of any option or future
right, all of Tenant's present and future rights to this Lease are then
terminated when the default occurs.

      (f) Utilities and Services. Upon any default by Tenant, Landlord may
immediately cease to provide all utilities and services to the Leased Premises
as provided under Section 11 herein.

      (g) Landlord's Remedies Cumulative. All rights and remedies of Landlord
herein enumerated shall be cumulative, and none shall exclude any other right or
remedy allowed by law. For the purposes of any suit brought or based hereon,
this Lease shall be construed to be a divisible contract, to the end that
successive actions may be maintained on this Lease as successive periodic sums
mature hereunder.

21.   Lender Requirements.

       (a) Subordination. Tenant agrees that this Lease is subject and
subordinate to any and all ground or underlying leases and to the lien of any
first mortgages or deeds of trust now on or which at any time may be made a lien
upon the Building, or any part thereof, and to all advances made or hereafter to
be made upon the security thereof. This subordination provision shall be
self-operative and no further instrument of subordination shall be required.
Tenant agrees to execute and deliver, upon request, within five (5) days demand
by Landlord, such further instrument or instruments confirming this
subordination as shall be desired by Landlord or by any mortgagee or proposed
mortgagee; and Tenant hereby constitutes and appoints Landlord as Tenant's
attorney-in-fact to execute any such instrument or instruments. Upon Tenant's
written request, Landlord shall use its best efforts to acquire from any such
mortgagee an agreement that any proceeding to foreclose, sell or any other
action taken under the mortgage shall not affect Tenant's rights to continue to
occupy the Leased Premises and exercise and enjoy all of its rights hereunder so
long as Tenant complies with the terms and provisions of this Lease, and
continues to make the payments required here-under to the appropriate designated
party, provided, Landlord's failure to acquire such an agreement shall not
mitigate Tenant's obligations hereunder. Tenant further agrees that, at the
option of the holder of any first mortgage or of the trustee under any first
deed of trust, this Lease may be made superior to said first mortgage or first
deed of trust by the insertion therein of a declaration that this Lease is
superior thereto.

      (b) Attornment. In the event any proceedings are brought for the
foreclosure of, or in the event of exercise of the power of sale under, any deed
to secure debt given by Landlord and covering the Leased Premises, Tenant shall
attorn to the purchaser upon any such foreclosure or sale and recognize such
purchaser as the owner and landlord under this Lease.

      (c) Financing. This Lease is subject to the approval of the mortgage
lender(s) providing mortgage financing for the Building, and disapproval of this
Lease by any such mortgage lender shall result in termination of this Lease. In
the event that any mortgage lender providing mortgage financing for the Building
requires, as a condition of such financing, that modifications to this Lease be
obtained, and

                                       20


<PAGE>




provided that such modifications (i) are reasonable, (ii) do not adversely
affect Tenant's use of the Leased Premises as herein permitted, (iii) do not
materially alter the approved plans for the Basic Work and Additional Work and
(iv) do not increase the rentals and other sums required to be paid by Tenant
hereunder, then Landlord may submit to Tenant a written amendment to this Lease
incorporating such required modifications, and, in the event Tenant does not
execute and return to Landlord such written amendment within ten (10) days after
the same has been submitted to Tenant, then Landlord shall thereafter have the
right, at its sole option, to terminate this Lease. Such option shall be
exercisable by Landlord giving Tenant written notice of termination, immediately
whereupon this Lease shall be terminated, and money or security therefor
deposited by Tenant with Landlord shall be returned to Tenant, and both Landlord
and Tenant shall thereupon be relieved from any and all further liability or
obligation hereunder.

       (d) Financial Statements. Tenant agrees, not more often than once per
calendar year, upon written notice by Landlord, to deliver to Landlord such
financial statements detailing its profits and losses, certified by a duly
authorized officer of Tenants if Tenant.

22. Estoppel Certificates. Tenant agrees, at any time and from time to time,
upon not less than ten (10) days prior written notice by Landlord, to execute,
acknowledge and deliver to Landlord a written estoppel certificate (i)
certifying that this Lease is unmodified and in full force and effect (or if
there have been modifications, stating the nature of same), (ii) stating the
Rent Commencement Date of the Lease Term, (iii) stating the amounts of Minimum
Annual Rent and Additional Rent and the dates to which the Minimum Annual Rent
and Additional Rent have been paid by Tenant, (iv) stating the amount of any
Security Deposit, (v) stating whether or not to the best knowledge of Tenant,
Landlord is in default in the performance of any covenant, agreement or
condition contained in this Lease, and, if so, specifying each such default of
which Tenant may have knowledge, (vi) stating that Tenant has no right to set
off and no defense against payment of the Minimum Annual Rent or Additional
Rent, (vii) address to which notices to Tenant should be sent. and (viii)
certifying such other matters as may be requested by Landlord. Any such
certificate delivered pursuant hereto may be relied upon by an owner of the
Building, any prospective purchaser of the Building, any mortgagee or
prospective mortgagee of the Building or of Landlord's interest therein, or any
prospective assignee of any such mortgage. Failure to deliver the aforesaid
certificate within the five (5) days shall be conclusive upon Tenant for the
benefit of Landlord and any successor to Landlord that this Lease is in full
force and effect and has not been modified except as may be represented by the
party requesting the certificate. Tenant shall be liable for any loss incurred
by Landlord resulting from Tenant's failure to timely execute and deliver any
estoppel certificate requested by Landlord, and shall reimburse Landlord for the
amount of any such loss upon demand, as Additional Rent.

23. Damage by Fire or Other Casualty. If the Leased Premises, or any other
portion of the Building shall, through no fault of Tenant or Tenant's agents,
servants, employees, customers, contractors, visitors or licensees, be damaged
by fire, the elements, unavoidable accident or other casualty:

      (a) Except as otherwise provided in subparagraph (b) hereof, Landlord, at
Landlord's expense, shall promptly restore the Leased Premises, and Tenant, at
Tenant's sole expense, shall promptly restore all leasehold improvements
installed in the Leased Premises by Tenant or at Tenant's request and its own
furniture, furnishings, trade fixtures and equipment and the rent shall not be
abated. No

                                       21


<PAGE>




penalty shall accrue for reasonable delay which may arise by reason of
adjustment of insurance on the part of Landlord, or on account of labor
problems, or any other cause beyond Landlord's reasonable control. If the damage
or destruction is such as to make the Leased Premises or any substantial part
thereof untenantable (in Landlord's judgment), and provided that such damage or
destruction is not due in whole or part to the act or omission of Tenant or
Tenant's agents, employees or invites, the Minimum Annual Rent shall abate
proportionately (based on proportion of the number of square feet rendered
untenantable to the total number of square feet of the Leased Premises), from
the date of the damage or destruction until the date the Leased Premises has
been restored by Landlord.

      (b) If the Leased Premises are substantially damaged or are rendered
substantially untenantable by fire or other casualty, or if Landlord's architect
certifies that the Leased Premises cannot be repaired within one hundred twenty
(120) working days of normal working hours, said period commencing with the
start of the repair work, or if Landlord shall decide not to restore or repair
the same, or if more than fifty percent (50%) of the gross leasable area of the
Building is rendered untenantable (even if the Leased Premises is undamaged) or
if Landlord shall decide to demolish the Building or not to rebuild it, then
Landlord may, within ninety (90) days after such fire or other casualty,
terminate this Lease by giving Tenant a notice in writing of such decision, and
thereupon the term of this Lease shall expire on the date specified in such
notice, or, if not date is so specified, by lapse of time upon the third day
after such notice is given, and Tenant shall vacate the Leased Premises and
surrender the same to Landlord. Upon the termination of this Lease under the
conditions hereinbefore provided, Tenant's liability for Minimum Annual Rent and
Additional Rent shall cease as of the day following the casualty.

      (c) The proceeds payable under all casualty insurance policies maintained
by Landlord on the Leased Premises shall belong to and be the property of
Landlord, and Tenant shall not have any interest in such proceeds. Tenant agrees
to look to Tenant's casualty insurance policies for the restoration and
replacement of the leasehold improvements installed in the Leased Premises by
Tenant or at Tenant's request and Tenant's fixtures, equipment and furnishings
in the Leased Premises, and in the event of termination of this Lease, for any
reason, following any such damage or destruction, Tenant shall promptly assign
to Landlord or otherwise pay to Landlord, upon Landlord's request, the proceeds
of said insurance and such other additional funds so that the total amount
assigned and/or paid by Tenant to Landlord shall be sufficient to restore
(whether or not any such restoration is actually to occur) all improvements,
fixtures, equipment and furnishings (excepting only Tenant's trade fixtures and
equipment) existing in the Leased Premises immediately prior to such damage or
destruction.

      (d) Notwithstanding anything to the contrary in this Section 23 or in any
other provision of this Lease, any obligation (under this Lease or otherwise) of
Landlord to restore all or any portion of the Leased Premises shall be subject
to Landlord's receipt of approval of the same by the mortgagee(s) of Landlord
(and any other approvals required by applicable laws), as well as receipt from
any such mortgagee(s) of such fire and other hazard insurance policy proceeds as
may have been assigned to any such mortgagee; it being agreed that if Landlord
has not received such approval(s) and proceeds within one hundred and eighty
(180) days after any such casualty, then Landlord shall have the option to
terminate this Lease, at any time thereafter, upon notice to Tenant.

                                       22


<PAGE>




24. Condemnation. In the event the whole or a substantial part of the Leased
Premises or the Building shall be taken for any public or quasi-public purpose
by any lawful power or authority by exercise of the right of appropriation,
condemnation or eminent domain, or sold to said authority to prevent such taking
(collectively referred to herein as a "taking"), Landlord shall have the right
to terminate this Lease effective as of the date possession is required to be
surrendered to said authority, and the Minimum Annual Rent and Additional Rent
shall be apportioned as of the date. For purposes of this section, a substantial
part of the Leased Premises or the Building shall be considered to have been
taken if, in Landlord's opinion, the taking shall render it commercially
undesirable for Landlord to permit this Lease to continue or to continue
operating the Leased Premises or the Building. Tenant shall not assert any claim
against Landlord or the taking authority for any compensation arising out of or
related to such taking and Landlord shall be entitled to receive the entire
amount of any award without deduction for any estate or interest of Tenant. If
Landlord does not elect to terminate this Lease, the Minimum Annual Rent and
Additional Rents shall be adjusted (based on the ratio that the number of square
feet of rentable area taken from the Leased Premises bears to the number of
rentable square feet in the Leased Premises immediately prior to such taking) as
of the date possession is required to be surrendered to said authority. Nothing
contained in this section shall be deemed to give Landlord any interest in any
award made to Tenant for the taking of personal property and fixtures belonging
to Tenant, as long as such award is made in addition to and separately stated
from any award made to Landlord for the Leased Premises or the Building.
Landlord shall have no obligation to contest any taking.

25. Landlord's Reserved Rights. The Landlord reserves the following rights:

      (a) To decorate, remodel, repair, alter or otherwise prepare the Leased
Premises for reoccupancy during the last ninety (90) days of the Lease Term, if
during or prior to that time Tenant vacates the Leased Premises; and

      (b) To show the Leased Premises to prospective tenants or brokers during
the last one hundred eighty (180) days of the term of this Lease, and to show
the Leased Premises to prospective purchasers, mortgagee, or assignee of any
mortgage on the Building at all reasonable times provided that reasonable prior
notice is given to Tenant in each case and that Tenant's use and occupancy of
the Leased Premises shall not be materially inconvenienced by any such action of
Landlord.

26. Landlord and Tenant Liability.

       (a) Landlord's Liability. It is understood and agreed that Landlord is a
Maryland limited partnership and/or joint venture and that no partner of the
partnership, as may now or hereinafter be constituted, shall have liability to
Tenant or any person claiming under, by or through Tenant on any action, claim,
suit or demand brought pursuant to the terms and conditions of this Lease or
arising out of the occupancy by the Tenant of the Leased Premises. Landlord, or
its agents, shall not be responsible or liable to the Tenant or its agents,
employees, contractors, customers or other visitors for any injury or damage
resulting from acts or omissions of persons occupying property adjoining the
Leased Premises, or any part of the Building of which the Leased Premises are a
part, or for any injury or damage to persons or property resulting from fire,
explosion, falling plaster, steam, gas, electricity, water, rain, dampness or
snow or leaks from or through any part of the Leased Premises or the Building,
including the roof, or from the pipes, conduits, appliances or plumbing works,
or from the roof, street or subsurface or

                                       23


<PAGE>




from any other place or by dampness or by any other cause of whatsoever nature,
unless caused by or due to the gross negligence of Landlord, its agents,
servants, or employees. All personal property and equipment located in the
Leased Premises shall be at the risk of Tenant.

      (b) Tenant's Liability. Tenant shall reimburse Landlord for all expense,
damages or fines, incurred or suffered by Landlord by reason of any breach,
violation or nonperformance by Tenant, or its agents, servants, or employees, of
any material covenant or material provision of this Lease or the Rules and
Regulations promulgated by Landlord hereunder from time to time, or by reason of
damage to persons or property caused by moving property of or for Tenant in or
out of the Building, or by the installation or removal of furniture or other
property of or for Tenant, or by reason of or arising out of the carelessness,
negligence or improper conduct of Tenant, or its agents, servants, employees,
invites or licensees in the use or occupancy of the Leased Premises.

      (c) Indemnity. Tenant shall indemnify Landlord and its agents and
employees and save them harmless from and against any and all claims, actions,
damages, liabilities and expenses in connection with loss of life, personal
injury and/or damage to property (i) arising from or out of the occupancy or use
by Tenant of the Leased Premises or any part thereof, or (ii) occasioned wholly
or in part by any act or omission of the Tenant, its agents, contractors,
employees, servants, invites or licensees, whether inside the Leased Premises or
elsewhere in the Building; provided, however, that this indemnification shall
not apply to any such injury, loss, damage or liability arising from any
omission, fault, negligence, or misconduct on the part of the Landlord, its
agents, servants, employees, contractors or licensees. In the event that
Landlord or its agents and employees shall, without fault on its or their part,
be made a party to any litigation commenced by or against Tenant, then Tenant
shall protect and hold the same harmless and shall pay all costs, expenses and
reasonable attorneys' fees incurred or paid in connection with such litigation.

      (d) Criminal Acts of Third Parties. Landlord shall not be liable in any
manner to Tenant, its agents, employees, licensees, invitees or contractors for
any injury or damage to Tenant, Tenant's agents, employees, licensees, invites,
or contractors or their property caused by the criminal or intentional
misconduct of third parties. All claims against Landlord for any such damage or
injury are hereby expressly waived by Tenant, and Tenant hereby agrees to hold
harmless and indemnify Landlord from all such damages and the expense of
defending all claims made by Tenant's agents, employees, licensees, invitees or
contractors arising out of such acts.

27. Tenant's Insurance.

       (a) Coverages. Tenant shall have issued, pay the premiums therefor, and
maintain in full force and effect during the Lease Term:

              (i) Commercial General Liability. A commercial general liability
insurance policy or policies (providing among other coverages: Blanket
Contractual, Personal Injury, independent Contractors, Products/Completed
Operations Hazard, Automobile Liability/Comprehensive Form, and Workers
Compensation) in which the Landlord (and such additional persons and/or entities
as Landlord may request) and Tenant shall be the insured, naming the Landlord
(and such additional persons and/or entities as Landlord may request) and Tenant
as insured parties in the amount of Two

                                       24


<PAGE>




Million and No/100 Dollars ($2,000,000.00) combined single limit general
liability coverage for bodily injury or property damage, which amount may be
increased from time to time by the Landlord in its reasonable determination;

              (ii) All-Risk Property. All-risk property insurance, including
theft, naming Landlord (and such additional persons and/or entities as Landlord
may request) and Tenant as insured, written at replacement cost value and with
replacement cost endorsement, covering all leasehold improvements installed in
the Leased Premises by Tenant or at Tenant's request and all of Tenant's
personal property in the Leased Premises (including, without limitation,
inventory, trade fixtures, floor coverings, furniture and other property
removable by Tenant under the provisions of this Lease);

              (iii) Workers' Compensation. If and to the extent required by law,
workers' compensation and employer's liability or similar insurance in form and
amounts required by law; and

              (iv) Additional Insurance. Such additional insurance as any
mortgagee of the Building may require.

      (b) Policy Requirements. In the event Tenant shall fail to provide such
insurance, or shall fail to pay the premiums when due, Landlord shall have the
right to cause such insurance to be issued and to pay the premiums therefor, or
any premiums in default, and to collect same as Additional Rent together with
interest at the Penalty Rate on the amount of such premiums from the date of
payment by Landlord until the date of repayment by Tenant. All such policies
shall contain only such reasonable deductible amounts as may be approved in
advance by Landlord and shall contain a provision that Landlord shall receive
not less than thirty (30) days advance notice in writing from the insurance
company of any intention of the insurance company to cancel such policy or
policies. Tenant shall provide written evidence to Landlord of its acquisition
of such policies no later than ten (10) days prior to the commencement of this
Lease and prior to any renewal date of such policies. All policies shall be
carried with an insurance company qualified to do business in the State of
Maryland, and rated A or better by the A.M. Best Company.

      (c) No Limitation of Liability. Neither the issuance of any insurance
policy required under this Lease nor the minimum limits specified herein shall
be deemed to limit or restrict in any way Tenant's liability arising under or
out of this Lease.

      (d) Notice of Fire and Accident. Tenant shall give Landlord immediate
notice in case of fire, theft, or accidents in the Leased Premises, and in case
of fire, theft or accidents in the Building if involving Tenant, its agents,
employees or invitees.

28. Waiver of Subrogation. Landlord and Tenant mutually covenant and agree that
each party, in connection with insurance policies required to be furnished in
accordance with the terms and conditions of this Lease, or in connection with
insurance policies which they obtain insuring such insurable interest as
Landlord or Tenant may have in its own properties, whether personal or real,
shall expressly waive any right of subrogation on the part of the insurer
against the Landlord (and any mortgagee requested by Landlord) or Tenant as the
same may be applicable, which right to the extent not prohibited or violative of
any such policy is hereby expressly waived, and Landlord and Tenant each
mutually waive all right of recovery, claims, losses and/or damages against each
other, their agents, or employees for any

                                       25


<PAGE>




loss, damage or injury of any nature whatsoever to property or person for which
either party is required by this Lease to carry insurance.

29. No Liens Permitted: Discharged. Tenant will not permit to be created or to
remain undischarged any lien, encumbrance or charge (arising out of any work
done or materials or supplies furnished, or claimed to have been done or
furnished, by any contractor, mechanic, laborer or materialman or any mortgage,
conditional sale, security agreement or chattel mortgage, or otherwise by or for
Tenant) which might be or become a lien or encumbrance or charge upon the
Building or any part thereof or the income therefrom. Tenant will not suffer any
other matter or thing whereby the estate, rights and interests of Landlord in
the Building or any part thereof might be impaired. If any lien, or notice of
lien on account of an alleged debt of Tenant or any notice of contract by a
party engaged by Tenant or Tenant's contractor to work on the Leased Premises
shall be filed against the Building or any part thereof, Tenant, within fifteen
(15) days after notice of the filing thereof, will cause the same to be
discharged of record by payment, deposit, bond, order of a court of competent
jurisdiction or otherwise. If Tenant shall fail to cause such lien or notice of
lien to be discharged within the period aforesaid, then, in addition to any
other right or remedy, Landlord may, but shall not be obligated to, discharge
the same either by paying the amounts claimed to be due or by procuring the
discharge of such lien by deposit or by bonding proceedings and in any such
event Landlord shall be entitled, if Landlord so elects, to compel the
prosecution of an action for the foreclosure of such lien by the lienor and to
pay the amount of the judgment in favor of the lienor with interest, costs and
allowances. Any amount so paid by Landlord and all costs and expenses, including
attorneys' fees, incurred by Landlord in connection therewith, shall constitute
Additional Rent payable by Tenant under this Lease and shall be paid by Tenant
to Landlord on demand. Nothing herein contained shall obligate Tenant to pay or
discharge any lien created by Landlord.

30. Signs and Advertisements. Landlord shall provide for Tenant, at Landlord's
expense, a notice in the Building directory, Building street sign, and a sign
for the entrance door to the Leased Premises in the type and manner Landlord
from time to time provides for tenants of the Building. No other sign,
advertisement, notice or any other thing of any kind whatsoever shall be
inscribed, painted, affixed or displayed in or about the Building by Tenant and
if any such sign, advertisement or notice is exhibited, Landlord shall have the
right to remove the same and Tenant shall be liable for any and all expenses
incurred by Landlord for said removal. Tenant agrees to maintain its entrance
door or entry sign in good condition and repair at all times.

31. Notices. All notices to be given under this Lease shall be in writing,
hand-delivered, sent by Federal Express, or mailed by United States Certified or
Registered Mail, postage prepaid. Notices should be delivered as follows:

      (a) To the Landlord at the address specified in Section 1(a)(18).

      (b) To the Tenant at the addresses specified in Sections l(a)(17).

Any such notice shall be deemed to be served on the date it is hand-delivered or
delivered by Federal Express, or on the third day after the date on which it is
deposited in the U.S. mails. Landlord and Tenant shall each have the right to
change

                                       26


<PAGE>




the person and/or address to which notices shall be delivered upon written
notice thereof to the other party sent pursuant to the provisions of this
paragraph.

32. Time. Landlord and Tenant acknowledge that time is of the essence in the
performance of any and all obligations, terms, and provisions of this Lease.

33. Postponement of Performance. In the event that either party hereto shall be
delayed or hindered in or prevented from the performance of any act required
hereunder by reason of strikes, labor troubles, inability to procure labor or
materials, failure of power, restrictive governmental laws or regulations,
riots, insurrection, war, acts of God, fire or other casualty or other reason of
a similar or dissimilar nature beyond the reasonable control of the party
delayed in performing work or doing acts required under the terms of this Lease,
then performance of such act shall be excused for the period of the delay and
the period for the performance of any such act shall be extended for a period
equivalent to the period of such delay. The provisions of this paragraph shall
not operate to excuse Tenant from the prompt payment of Minimum Annual Rent or
Additional Rent and shall not operate to extend the term of this Lease. Delays
or failures to perform resulting from lack of funds shall not be deemed delays
beyond the reasonable control of a party.

34. No Waiver. No provision of this Lease shall be deemed to have been waived by
Landlord, unless such waiver be in writing signed by Landlord. No waiver by
Landlord of any breach by Tenant of any of the terms, covenants, agreements, or
conditions of this Lease shall be deemed to constitute a waiver of any
succeeding breach thereof, or a waiver of any breach of any of the other terms,
covenants, agreements, and conditions herein contained.

        No employee of Landlord or of Landlord's agents shall have any authority
to accept the keys of the Leased Premises prior to termination of the Lease, and
the delivery of keys to any employee of Landlord or Landlord's agents shall not
operate as a termination of the Lease or a surrender of the Leased Premises. The
receipt by Landlord of any payment of Minimum Annual Rent or Additional Rent
with knowledge of the breach of any covenant of this Lease shall not be deemed a
waiver of such breach. The failure of Landlord to enforce any of the Rules and
Regulations made a part of this Lease, or hereafter adopted, against Tenant or
any other tenant in the Building shall not be deemed a waiver of any such Rules
and Regulations.

35. Limitation of Landlord's Liability. In consideration of the benefits
accruing hereunder, Tenant and all successors and assigns of Tenant covenant and
agree that in the event of any actual or alleged failure, breach or default
hereunder by Landlord: (a) the sole and exclusive remedy shall be against the
interest of Landlord in the Building of which the Leased Premises are a part;
(b) neither Landlord nor any partner of Landlord shall be personally liable with
respect to any claim arising out of or related to this Lease; (c) no partner of
Landlord shall be sued or named as a party in any suit or action (except as may
be necessary to secure jurisdiction of Landlord); (d) no service of process
shall be made against any partner of Landlord (except as may be necessary to
secure jurisdiction of Landlord); (e) any judgment granted against any partner
of Landlord may be vacated and set aside at any time as if such judgment had
never been granted; and (f) these covenants and agreements are enforceable both
by Landlord and also by any partner of Landlord.

                                       27


<PAGE>




36. Transfer of the Building. In the event of the sale or other transfer of
Landlord's right, title and interest in the Leased Premises or the Building
(except in the case of a sale-leaseback financing transaction in which Landlord
is the lessee), Landlord shall transfer and assign to such purchaser or
transferee all amounts of pre-paid Minimum Annual Rent, and Landlord thereupon
and without further act by either party hereto shall be released from all
liability, obligations, and covenants, express or implied, hereunder derived
from this Lease arising out of any act, occurrence or omission relating to the
Leased Premises or this Lease occurring after the consummation of such sale or
transfer, provided that the transferee shall assume all of Landlord's
obligations hereunder from the date of such transfer. Tenant shall have no right
to terminate this Lease nor to abate Minimum Annual Rent nor to deduct from, nor
set-off, nor counterclaim against Minimum Annual Rent because of any sale or
transfer (including, without limitation, any sale-leaseback) by Landlord or its
successors or assigns. This lease shall not be affected by any such sale, and
Tenant agrees to attorn to the purchaser or transferee. Upon any sale or other
transfer as above provided (other than a sale-leaseback), or upon any assignment
of Landlord's interest herein, it shall be deemed and construed conclusively,
without further agreement between the parties, that the purchaser or other
transferee or assignee has assumed and agreed to perform the obligations of
Landlord thereafter accruing.

37. Waiver of Counterclaim and Trial by Jury. Landlord and Tenant waive their
right to trial by jury in any action, proceeding or counterclaim brought by
either of the parties hereto against the other (except for personal injury or
property damage) on any matters whatsoever arising out of or in any way
connected with this Lease, the relationship of Landlord and Tenant, Tenant's use
of or occupancy of the Leased Premises, and any emergency statutory or any other
statutory remedy. Tenant shall not interpose any counterclaim or counterclaims
or claims for set-off, recoupment or deduction of Minimum Annual Rent or
Additional Rent in a summary proceeding for nonpayment of Minimum Annual Rent or
Additional Rent or other action or summary proceeding based on termination,
holdover or other default in which Landlord seeks repossession of the Leased
Premises from Tenant.

38. Lease Recording. It is understood and agreed that Landlord shall not record
the within Lease Agreement among the Land Records of Baltimore County, Maryland,
for any purpose.

39. Notice of Default to Landlord and Mortgagee and Right to Cure. Tenant shall
give, by registered mail, a written notice of any failure by Landlord to perform
any of its obligations under this Lease to Landlord which shall specifically set
forth the nature of the nonperformance by the Landlord and shall give the
Landlord thirty (30) days within which to cure such default or non-performance.
However, if such default or non-performance reasonably requires more than thirty
(30) days to cure, Landlord shall not be in default if such cure is commenced
within such thirty (30) day period and thereafter diligently pursued to
completion. Said notice of default shall be a condition precedent to the
institution by Tenant of any judicial proceedings for nonperformance or default
against the Landlord. Tenant agrees to give any mortgagee and/or Trust Deed
Holders whose name and address have been furnished to Tenant in writing, by
registered mail, a copy of any notice of default served upon the Landlord.
Tenant further agrees that if Landlord shall fail to cure such default within
the time provided for in this Lease Agreement, then the mortgagees and/or Trust
Deed Holders shall have an additional thirty (30) days within which to cure such
default or, if such default cannot be cured within that

                                       28


<PAGE>




time, then such additional time as may be necessary if within such thirty (30)
days, any mortgagee and/or Trust Deed Holders has commenced and is diligently
pursuing the remedies necessary to cure such default, in which event this Lease
shall not be terminated while such remedies are being so diligently pursued.

40.   Miscellaneous Provisions.

construal, validity, performance and enforcement of this Lease.

each has full right, power and authority to enter into this Lease upon the terms
and conditions herein set forth. If Tenant signs as a corporation, each of the
persons executing this Lease on behalf of Tenant does hereby covenant and
warrant that Tenant is a duly authorized and existing corporation, qualified to
do business in the jurisdiction in which the Leased Premises is located, that
the corporation has

                                       29

full right and authority to enter into this Lease, and that each and both of the
persons signing on behalf of the corporation were authorized to do so. If Tenant
signs as a partnership, each of the persons executing this Lease on behalf of
Tenant does hereby covenant and warrant that Tenant is a duly formed and validly
existing partnership, that the partnership has full right and authority to enter
into this Lease, and that each of the persons signing on behalf of the
partnership were authorized to do so.

      (k) Examination of Lease. Submission of this Lease for examination or
signature by Tenant shall not constitute reservation of or option for Lease, and
the same shall not be effective as a Lease or otherwise until execution and
delivery by both Landlord and Tenant.

      (l) Interpretation. Although the printed provisions of this Lease were
drawn by Landlord, this Lease shall not be construed for or against Landlord or
Tenant, but this Lease shall be interpreted in accordance with the general tenor
of the language in an effort to reach the intended result.

      (m) Entire Agreement; Modification. This Lease contains the entire
agreement between the parties, and any agreement hereafter made shall be
ineffective to change, discharge or effect an abandonment in whole or in part
unless such agreement is in writing and signed by the party against whom
enforcement of the change, modification, discharge or abandonment is sought.
Acceptance of, or acquiescence in, a course of performance rendered under this
or any prior agreement between the parties or their affiliates shall not be
relevant or admissible to determine the meaning of any term of this Lease.

      (n) Termination. This Lease and the tenancy hereby created shall cease and
determine at the end of the Lease Term, or any extension or renewal thereof,
without the necessity of any notice from either Landlord or Tenant to terminate
the same, and Tenant hereby waives notice to vacate the Leased Premises and
agrees that Landlord shall be entitled to the benefit of all provisions of law
respecting the summary recovery of possession of premises from a tenant holding
over to the same extent as if statutory notice had been given. For the period of
three (3) months prior to the expiration of the Lease Term or of any extension
or renewal thereof, Landlord shall have the right to show the Leased Premises
and all parts thereof to prospective tenants between the hours and 9:00 am and
5:00 pm, on any day except Saturday and Sunday and except any legal holiday on
which Tenant shall not be open for business.

      (o) Corporate Approval. If Tenant is a corporation, Tenant covenants and
warrants that it has the requisite corporate approval to enter into and execute
this Lease Agreement and accordingly, shall provide to Landlord, as soon as
practicable following execution of this Lease, a copy of an executed resolution
by its Board of Directors, authorizing the execution of the Lease Agreement and
authorizing the individual executing this Lease to execute said Agreement on
behalf of and in the name of the Corporation. If Tenant shall fail to provide
the executed resolution within the time period required under this Section,
Landlord may, at its option, declare this Lease to be null and void and of no
further force or effect. If Tenant is a corporation it acknowledges that this
Lease is executed under seal and that a twelve year period of limitation
applies.

                                       30

      (p) Approval of Mortgage. This Lease is contingent upon the approval of
any and all mortgagees or other lenders of the Landlord. Landlord shall have
thirty (30) days from the execution of this Lease to obtain all necessary
approvals from this mortgagee or other lenders; and thereafter shall have the
right to extend said approval period an additional ten (10) days upon written
notice to Tenant. If said approvals cannot be obtained within the aforesaid
period, this Lease and the rights and duties of the parties hereunder, shall be
null and void and be of no further effect.

      (q) Zoning and Licensing Approvals. Anything herein elsewhere contained to
the contrary, this Lease and all the terms, covenants, and conditions hereof are
in all respect subject and subordinate to all zoning restrictions affecting the
Leased Premises, and the Building in which they are located, and the Tenant
agrees to be bound by such restrictions. The Landlord further does not warrant
that any license or licenses, permit or permits, which may be required for the
business to be conducted by the Tenant on the Leased Premises will be granted,
or, if granted, will be continued in effect or renewed, and any failure to
obtain such licence or licences, permit or permits, or any revocation thereof or
failure to renew the same, shall not release the Tenant from its obligations
under this Lease Agreement.

41. Quiet Enjoyment. If and so long as Tenant pays rent and additional rent
reserved by this Lease, and performs and observes all the covenants and
provisions hereof, Tenant shall quietly enjoy the Leased Premises, subject,
however, to the terms and provisions hereof.

42. Remedies Cumulative. No mention in this Lease of any specific right or
remedy shall preclude Landlord from exercising any other right or from having
any other remedy, or from maintaining any action to which it may otherwise be
entitled, either at law or equity; and the failure of Landlord to insist in any
one or more instances upon a strict performance of any covenant of this Lease or
to exercise any option or right herein contained shall not be construed as a
waiver of relinquishment for the future of such covenant, right or option, but
the same shall remain in full force and effect unless the contrary is expressed
in writing by Landlord.

43. Binding Effect. This Agreement and the covenants and conditions herein
contained shall be binding upon and shall inure to the benefit of Landlord, its
heirs, personal representatives, successors and assigns, and shall be binding
upon Tenant, its heirs, personal representatives, successors and assigns, and
shall inure to the benefit of Tenant and only such assigns of Tenant to whom the
assignment by Tenant has been consented to by Landlord.

      IN WITNESS WHEREOF, the parties hereto have duly executed this Agreement
the day and year first above written.

         (b) References and Conflicts. References appearing in Section 1(a) are
intended to designate some of the other places in the Lease where additional
provisions are applicable to the particular fundamental Lease provisions appear.
These references are for convenience only and shall not be deemed all inclusive.
Each reference in the Lease to any of the fundamental Lease provisions contained
in Section 1(a) shall be construed to incorporate all of the terms provided for
under such provisions, and such provisions shall be read in conjunction with all
other provisions of the Lease applicable thereto. If there is any conflict
between any of the fundamental Lease provisions set forth in Section 1(a) and
any other provisions of the Lease, the latter shall control.

         (c) Exhibits. The following drawings and special provisions are
attached hereto as exhibits and hereby made a part of this Lease:

             Exhibit A. Floor Plan of Leased Premises
             Exhibit B. Rules and Regulations

      (d) Addendums. The following special provisions are attached hereto as
addendums and hereby made a part of this Lease.

             Addendum 1 - Leased Premises.

2.    Premises.

      (a) Leased Premises. Landlord hereby leases to Tenant, and Tenant hereby
rents from Landlord, the Leased Premises as specified in Section 1(a)(1) located
in the building specified in Section 1(a)(2) (the "Building"). The leased
premises shall consist of approximately the square footage of rentable floor
space as specified in Section 1(a)(3), which included an agreed common area
factor of twelve percent (12%), and as outlined in red on the floor plan
attached hereto as Exhibit A. For the purposes of determining the square footage
of the Leased Premises, leasehold space is calculated by measuring from the
outside of any exterior walls of the Leased Premises to the center line of any
partitions constructed which separate the Leased Premises from the remaining or
adjacent premises of the Building.

                                        2

      (b) The Building. Landlord and Tenant acknowledge that the gross leasable
area in the Building is specified in Section 1(a)(4) ("Gross Leasable Area" or
"GLA"). The GLA shall be used hereinafter for purposes of computing Tenant's
proportionate share of certain expenses payable to Landlord as Additional Rent.
Landlord reserves the right to modify the GLA of the Building from time to time
during the Lease Term as a result of construction of new improvements or the
demolition of existing improvements.

      (c) Tenant's Proportionate Share. Tenant's proportionate share of certain
expenses hereinafter made payable to Landlord as additional rent is specified in
Section 1(a)(5). Said computation is based upon the ratio of the total rentable
area in the Leased Premises to the GLA of the Building. The Proportionate Share
shall be modified during the Lease Term in the event that the GLA of the
Building is modified as described in Section 2(b) above.

3.    Term.

      (a) Lease Term. The term of the Lease (sometimes herein called the "Lease
Term") shall commence on the "Rent Commencement Date," January 1, 1997, and
shall continue for a period of nine (9) years from the first day of the calendar
month next following the first day of the Term, unless sooner terminated as
herein provided.

      (b) Acceptance of Leased Premises. Landlord shall deliver, and Tenant
agrees to accept, possession of the Leased Premises in an "as is" condition,
subject, however, to Landlord's performance of its agreed obligation to replace
at no charge to Tenant the carpet in the rear portion of the fourth floor. By
entering into possession, Tenant shall be deemed to have accepted the Leased
Premises, to have acknowledged that the same are in the condition called for
hereunder and to have agreed that the obligations of the Landlord imposed for
the delivery of the Premises have been fully performed. It is expressly
understood and agreed that Landlord has made no representations or warranties
with respect to the Leased Premises.

4.    Rent.

      (a) Minimum Annual Rent. The minimum Annual Rent reserved hereunder shall
be as specified in Section 1(a)(8) which shall be payable by Tenant to the
Landlord during each Lease Year of the Lease Term in twelve (12) equal monthly
installments of Basic Monthly Rent each as specified in Section (a)(9), due in
advance, without notice or demand, and without set-off, deduction or abatement
of any kind, on the first day of every calendar month thereafter during the
Term. Rent shall be paid to Landlord (or its agent) as specified in Section
1(a)(18), or to such other persons or at such other address as Landlord may
designate from time to time.

      (b) Annual Adjustments to Minimum Annual Rent. On the first day of the
second Lease Year, and on the first day of each Lease Year thereafter during the
Lease Term, the Minimum Annual Rent (than in effect) shall be increased by 3
percent (3%).

      (c)    Additional Rent.

             (i) General. Whenever it is provided by the terms of this Lease
that Tenant is required to make any payment to Landlord other than of Minimum
Annual Rent, such payment shall be deemed to be additional rent ("Additional
Rent").

expense, performs an obligation of Tenant pursuant to the terms of this Lease,
the actual out-of-pocket costs and expenses incurred by Landlord in performance
of such obligations shall be Additional Rent.

       (d)    Additional Rent Estimates and Adjustments.

              (i) On or before April 30 (or as soon thereafter as practicable)
of each calendar year, Landlord will submit to Tenant a comparative statement of
the actual increases incurred in Basic Operating Expenses for the preceding
calendar year over the Base Operating Expense Amount, setting forth in
reasonable detail: (i) a schedule of Basic Operating Expenses for the preceding
calendar year, and the amount of the Excess Operating Expenses for such
preceding year; (ii) the amount, if any, paid by Tenant to Landlord during the
preceding calendar year on account of the Excess Operating Expenses for such
preceding year; and (iii) the amount due from Tenant on account of the Excess
Operating Expenses for such preceding year, or the amount due from Landlord to
Tenant because of overpayment by Tenant on account of Excess Operating Expenses.
Landlord's comparative statement of Operating Expenses shall also include
Landlord's good faith estimate of Excess Operating Expenses for the then-current
calendar year and an estimated "Monthly Portion of Excess Operating Expenses"
equal to one-twelfth (1/12) of said good faith estimate of Excess Operating
Expenses.

              (ii) Tenant shall pay Landlord, within thirty (30) days of
Tenant's receipt of such statement, as Additional Rent, any amounts due from
Tenant on account of Excess Operating Expenses for the preceding year. Tenant
shall also make payments to Landlord, on account of the Excess Operating
Expenses for the then current calendar year, as follows:

                     (A) On the first day of the first full month following
receipt by Tenant of the Landlord's comparative statement of Basic Operating
Expenses, Tenant shall pay to Landlord an amount equal to the Monthly Portion of
Excess Operating Expenses multiplied by the number of months elapsed in the
current calendar year (including the month in which the payment is made); and

                     (B) Commencing on the first day of the second full month
following receipt by Tenant of Landlord's comparative statement of Basic
Operating Expenses, and continuing until the receipt by Tenant of the next
annual comparative statement, the minimum monthly installments of rent due
hereunder shall be increased by an amount equal to the Monthly Portion of Excess
Operating Expenses.

              (iii) Landlord shall refund any overpayment made by Tenant within
thirty (30) days after Landlord's submission to Tenant of the aforesaid
operating charge statement for such calendar year.

              (iv) Contemporaneously with presentation of Landlord's statement
showing actual figures for the year, Landlord shall furnish to Tenant, in
writing, a detailed statement of Basic Operating Expenses and copies of Real
Estate Tax bills. If it shall be determined that there is an error in Landlord's
statement, Tenant shall be entitled to a credit for any overpayment, or, if
Landlord billed Tenant less than should have been billed to Tenant, Tenant shall
pay such difference to Landlord. Any payment, refund or credit made pursuant to
Section 4(c) or 4(d) shall be made without prejudice to any right of Tenant to
dispute, or of Landlord to correct, any item(s) as billed pursuant to the
provision hereof; provided, however, such right to correct or adjust rental
payments shall terminate at the expiration of two (2) years after the date any
payment shall have become due.

              (v) Tenant's obligation to pay any Additional Rent accruing during
the Lease Term pursuant to this Section shall apply pro rata to the
proportionate part

                                        6


<PAGE>




of the calendar year as to Basic Operating Expenses, in which this Lease begins
or ends, for the portion of each such year during which this Lease is in effect.
Such obligation to make payments of such Additional Rent shall survive the
expiration or sooner termination of the Lease Term, whether or not this Lease is
superseded by a subsequent lease of the Leased Premises or of any other space or
Tenant leaves the Building; any such superseding lease shall not serve to
supersede Tenant's obligation for any such additional rent unless it makes
express reference thereto and recites that such additional rent is abated in
consideration of the superseding lease.

              (vi) If, during the Term of this Lease, there shall be a reduction
or elimination of any particular component of Basic Operating Expenses by reason
of the introduction of a labor-saving device, energy conservation device,
capital improvement or replacement installed by Landlord, the corresponding item
of expense in the Base Operating Expense shall be eliminated or reduced in the
same proportion as the reduction of that item in the Basic Operating Expense for
the purposes of calculating Tenant's share of Excess Operating Expenses.

              (vii) In the event that Landlord shall make a capital expenditure
for an Essential Capital Improvement (as hereinafter defined) during the Term of
this Lease, the annual amortization of such expenditure (determined by dividing
the amount of the expenditure by the useful life of the improvement) plus
interest on the unamortized balance at the rate actually paid by Landlord for
funds borrowed by Landlord to construct or otherwise provide such Essential
Capital Improvement, shall be deemed an Operating Expense for each year of such
useful life. As used herein, an "Essential Capital Improvement" means any of the
following: (A) a labor saving device or other installation, improvement or
replacement which reduces Operating expenses; (B) an installation or improvement
required by reason of any law, ordinance or regulation of any governmental or
quasi-governmental body, which requirement did not exist (or was not applicable
to the Building) on the date of execution of this Lease; or (C) an installation
or improvement which directly enhances the safety of tenants in the Building
generally (as, for example, but without limitation, for fire safety or
security); provided, however, any expense treated as an Essential Capital
Improvement hereunder must, at Tenant's option and expense, be certified by
independent auditors for Landlord as constituting an Essential Capital
Improvement under generally accepted accounting principles.

      (e) Payment of Rent. In the event Minimum Annual Rent or Additional Rent
is not paid within ten (10) days after the same is due, a late charge equal to
five percent (5%) of the delinquent amount shall be assessed as liquidated
damages for the additional administrative charges incurred by Landlord as a
result of such late payment. Tenant also agrees to pay all reasonable attorney
fees incurred by Landlord as a result of Tenant's delinquent payment of rent. No
payment by Tenant or receipt by Landlord of lesser amounts of rent than those
herein stipulated shall be deemed to be other than on account of the earliest
unpaid stipulated rent. No endorsement or statement on any check or any letter
accompanying any check or payment as rent shall be deemed an accord and
satisfaction, and Landlord may accept such check or payment without prejudice to
Landlord's right to recover the balance of such rent or pursue any other remedy
provided in this Lease. If Landlord shall pay any monies, or incur any expenses
in correction of violation of covenants herein set forth, the amount so paid or
incurred shall, at Landlord's option, and on written notice to Tenant, be
considered Additional Rent payable by Tenant with the first installment of
rental thereafter becoming due and payable. If Landlord receives from Tenant two
(2) or more returned or "bounced" checks in any twelve (12)

                                        7


<PAGE>




month period, Landlord may require all future rent be paid by cashier's or
certified check.

5. Security Deposit. Tenant has deposited with Landlord the sum specified in
Section 1(a)(12). Said deposit shall constitute advance rental and shall be held
by Landlord as security for the faithful performance by Tenant of all the terms,
covenants and conditions of this Lease to be kept and performed by Tenant during
the Lease Term. If, at any time during the Lease Term, any payment of Minimum
Annual Rent or Additional Rent herein reserved shall be overdue and unpaid, the
Landlord may, at its option, appropriate and apply any portion of said security
deposit to the payment of any such overdue rent or other sum. Landlord shall
have the unrestricted right (but not the obligation) to apply any part of the
Security Deposit to cure any Default (as described in Section 20 hereof).

      In the event of the failure of Tenant to keep and perform any other items,
covenants and conditions of the Lease to be kept and performed by Tenant, then
Landlord, at its option, may appropriate and apply the entire security deposit,
or so much thereof as may be necessary, to compensate Landlord for loss or
damage sustained or suffered by Landlord due to such breach by Tenant. Should
the entire security deposit, or any portion thereof, be appropriated and applied
by Landlord for the payment of overdue rent, to cure any default, or other sums
due and payable to Landlord by Tenant hereunder, then Tenant shall remit to
Landlord, within ten (10) days of the written demand of Landlord, a sufficient
amount in cash to restore the security deposit to the original sum. Tenant's
failure to do so shall constitute a breach of the Lease. Should Tenant comply
with all of said terms, covenants and conditions of the Lease and promptly pay
all Minimum Annual Rent and Additional Rent herein provided as it falls due,
then the security deposit shall be returned in full, without interest, to Tenant
within thirty (30) days of the Expiration Date or earlier termination of the
Term of this Lease. Tenant shall have no right to direct the application of any
part of the Security Deposit.

      Landlord may deliver the funds deposited hereunder by Tenant to the
purchaser of Landlord's interest in the building and/or the Leased Premises in
the event that such interest is sold, and thereupon Landlord shall be discharged
from any further liability with respect to such security deposit.

6. Improvement of the Leased Premises. Intentionally deleted.

7. Alterations or Improvements by Tenant. Except for the incidental hanging of
pictures, installation of shelves, and other painting and decoration of the
Leased Premises which do not affect the structure of the Leased Premises, Tenant
shall not make any alterations, additions, or improvements, structural or
otherwise (collectively, "Alterations") in the Leased Premises (such as
carpeting, telephone installation, decoration and installation of specialized
equipment), without the prior written consent of Landlord, which consent shall
not be unreasonably withheld. Tenant shall not install any equipment of any
nature whatsoever which may affect the insurance rating of the Building, or
which may necessitate any changes, replacements or additions to the water
system, plumbing system, heating system, air-conditioning system, telephone
system or the electrical system of the Leased Premises, without the prior
written consent of Landlord, which consent shall not be unreasonably withheld.
Tenant shall pay all costs to make such changes, replacements or additions.

      Tenant hereby agrees that all Alterations made in, to, or on the Leased
Premises shall, unless otherwise provided by written agreement, be the property
of Landlord

                                        8


<PAGE>




and shall remain upon and be surrendered with the Leased Premises on the
Expiration Date or other termination of this Lease, unless Landlord shall, prior
to such expiration or termination have given Tenant not less than 15 days prior
written notice to remove the same, in which event Tenant shall at its expense
forthwith remove such Alterations. Any or all wiring and cabling, such as
telephone, computer and data wires installed by Tenant shall be removed by
Tenant at its sole cost, and the Leased Premises shall be restored to their
original condition by the Expiration Date, ordinary wear and tear excepted. All
property permitted or required to be removed by Tenant at the end of the term
remaining in the Leased Premises after Tenant's removal shall be deemed
abandoned and may, at the election of Landlord, either be retained as Landlord's
property or may be removed from the premises by Landlord at Tenant's expense.

8.    Use of Leased Premises.

       (a) Use. Tenant shall use and occupy the Leased Premises for the singular
purpose specified in Section 1(a)(11) and for no other purpose. Tenant shall not
use or permit the Leased Premises to be used for any other purpose or purposes
without the prior written consent of Landlord, which consent may be granted or
withheld in its sole discretion.

      (b) Compliance. Tenant, at its expense, shall comply with the laws, rules
and regulations of any federal, state or municipal authority, or the Maryland
Fire Underwriters Rating Bureau, or with any notice from any public officer
pursuant to law, or with any notice from any insurance company pertaining to
Tenant's occupancy or use of the Leased Premises, whether such notice shall be
served on Landlord or Tenant. In furtherance of the foregoing, and provided
Tenant shall first have obtained Landlord's prior written consent (which Tenant
agrees to promptly request), Tenant shall, at Tenant's sole cost and expense,
make such changes, alterations, renovations or modifications to the Leased
Premises (except for structural repairs) which are necessitated or required by
any such Law.

              (i) Legal. Tenant shall not use or permit the Leased Premises or
any part thereof to be used in violation of any present or future applicable
law, regulation or ordinance, or of the certificate of occupancy issued for the
Building or the Leased Premises, and shall immediately discontinue any use of
the Leased Premises which is declared by any governmental authority having
jurisdiction to be in violation of law or said certificate of occupancy. Tenant
will not use or permit the Leased Premises to be used for any purposes that
interfere with the use and enjoyment of the Building by Landlord or the other
tenants, which will increase the existing rate of insurance on the Building or
which violate the requirements of any insurance company insuring the Building or
its contents, or which, in Landlord's sole discretion, impair the reputation of
the Building. Tenant shall refrain from and discontinue such use immediately
upon receipt of written notice from Landlord.

              (ii) Fire and Safety. Tenant shall not do, or permit anything to
be done in the Leased Premises, or bring, use or keep anything therein, which
will in any way increase the rate of fire insurance on the Building, or
invalidate or conflict with fire insurance policies on the Building, fixtures or
on property kept therein. Tenant agrees that any increases of fire insurance
premiums on the Building or contents caused by the occupancy of Tenant and any
expense or cost incurred in consequence of negligence or the willful action of
Tenant, Tenant's employees, agents, servants, invitee, or licensees shall be
deemed Additional Rent and paid as accrued.

                                        9

      (c) Environmental Protection. Tenant and Tenant's employees and agents
shall not dispose of any oil, petroleum or chemical liquids or solids, liquid or
gaseous products or any hazardous waste or hazardous substance including,
without limitation, asbestos (hereinafter collectively referred to as "hazardous
waste"), as those terms are used in the Comprehensive Environmental Response,
Compensation and Liability Act of 1980, or in any other federal, state or local
law governing hazardous substances (hereinafter referred to as the "Act"), as
such laws may be amended from time to time at, upon, under or within the Leased
Premises or the Building or the land on which it is built, or into the plumbing
or sewer or water system servicing the Leased Premises or the Building, nor
shall Tenant, its employees or agents cause or permit the discharge, spillage,
uncontrolled loss, seepage or filtration of any hazardous waste at, upon, under
or within the Leased Premises or the Building or the land or into the plumbing
or sewer or water system servicing the same. Tenant shall comply in all respects
with the requirements of the Act and related regulations, and shall notify
Landlord immediately in the event of its discovery of any hazardous waste at,
upon, under or within the Leased Premises or the Building or the land.

      (d) Indemnification. Tenant shall indemnify Landlord against all costs,
expenses, liabilities, losses, damages, injunctions, suits, fines, penalties,
claims, and demands, including reasonable attorneys' fees, arising out of any
violation of or default in the covenants of this Section 8. The provisions of
Sections 8(b) and (c) and this Section 8(d) shall survive the expiration of the
Lease Term.

      (e) Moving and Deliveries. No freight, furniture, heavy machinery, heavy
equipment, including computer equipment or other bulky matter or fixtures of any
description shall be transferred into or out of the Building or carried in the
elevators, without Landlord's prior written consent and approval. In obtaining
the Landlord's approval as required under this paragraph, Tenant agrees to
provide Landlord with all technical specifications concerning the equipment and
machinery and to pay the costs of any and all structural changes which in the
sole discretion of the Landlord are required to be made in order to safely and
efficiently accommodate such equipment or machinery. If such machinery or
equipment requires special handling, Tenant agrees to employ only persons
holding the proper licences to do said work, and that all work in connection
therewith shall comply with any applicable Federal, State, County or other
governing laws, rules or regulations. Tenant shall promptly remove from the
public areas within or adjacent to the Building any of Tenant's property
delivered or deposited there, and shall be liable for any damage to the Building
or the Leased Premises caused by its moving and deliveries.

      (f) Excessive Floor Load. Landlord shall have the right to prescribe the
weight and method of installation and position of safes or other heavy fixtures
or equipment. Tenant will not, without Landlord's prior written approval,
install in the Leased Premises any fixtures, equipment or machinery that will
place a load upon the floor exceeding the designed floor load capacity. Tenant
shall be liable for all damage done to the Building by installing or removing a
safe or any other article of Tenant's office equipment, or due to its being in
the Leased Premises. Landlord shall repair any such damage at Tenant's expense,
and Tenant shall pay the cost therefor to Landlord upon demand, as Additional
Rent.

9. Taxes on Tenant's Property. Tenant shall be liable for, and shall pay at
least ten (10) days before delinquency, all taxes levied against any personal
property or trade fixtures placed by Tenant in or about the Leased Premises. If
any such taxes

                                       10


<PAGE>




on Tenant's personal property or trade fixtures are levied against Landlord or
Landlord's property, or if the assessed value of the Leased Premises is
increased by the inclusion therein of a value placed upon such personal property
or trade fixtures of Tenant, and if Landlord, after written notice to Tenant,
pays the taxes based upon such increased assessments (which Landlord shall have
the right to do regardless of the validity thereof, but under protest if
requested by Tenant), Tenant shall upon demand repay as Additional Rent to
Landlord a sum equal to the taxes levied against Landlord or the portion of such
taxes resulting from such increase in the assessment; provided that, in any such
event, Tenant shall have the right, at Tenant's sole cost and expense, to bring
suit to recover the amount of any such taxes so paid under protest, and any
amount so recovered shall belong to Tenant.

10. Rules and Regulations. Tenant covenants on behalf of itself, its employees,
agents, licensees and invitees to comply with the rules and regulations set
forth in Exhibit B, which is attached hereto and made a part hereof (the "Rules
and Regulations"). Landlord shall have the right, in its sole discretion, to
make reasonable additions and amendments to the Rules and Regulations from time
to time and Tenant covenants that Tenant, its employees, agents, licensees and
invitees will comply with additions and amendments to the Rules and Regulations
upon Landlord's provision to Tenant of a written copy of the same. Any
unremedied default by Tenant, or any other party set forth above, of any of the
material provisions of the Rules and Regulations as set forth in Exhibit B, or
as amended from time to time, shall be considered to be a default under the
terms of this Lease. Nothing contained in this Lease shall be construed to
impose upon Landlord any duty or obligation to enforce the Rules and
Regulations, or any amendments or additions thereto, against any other tenant.
Landlord shall have no liability to Tenant or any other party for violations of
the Rules and Regulations by any party whatsoever. If there is any inconsistency
between this Lease and the Rules and Regulations, the Lease shall govern.

11.   Utilities and Services.

       (a) Building Standard Services and Utilities. As long as Tenant is not in
default under any of the covenants of this Lease, Landlord shall, if and insofar
as existing facilities permit, furnish sufficient electric current for routine
and normal requirements for lighting and typical office equipment and machinery,
such as typewriters, calculators, personal computers, small copiers and similar
items, subject to the limitations of Section 11(b). Landlord shall furnish hot
and cold water for lavatory and drinking purposes, lavatory supplies, and
Building standard fluorescent tube replacements and nightly cleaning and
janitorial services Monday through Friday. Landlord further agrees to furnish
heating and cooling during the appropriate seasons of the year, during the
Standard Building Operating Hours and on the days set forth in Section l(a)(15),
exclusive of the Building Holidays specified in Section l(a)(16), with holidays
falling on Saturday observed both on said day and on the preceding Friday, and
holidays falling on Sunday observed on the following Monday.

      (b) Overtime Services. Landlord shall be under no obligation to furnish
electric power at any hours other than normal business hours, or for the
operation of any other electrical equipment or appliance, unless arrangements
for such after-hours operations, and for the installation of such electrical
equipment or appliance, shall have been made pursuant to terms and conditions
acceptable to Landlord and embodied in a separate written agreement between
Landlord and Tenant. In the event that Tenant uses electrical services in excess
of that required for normal office use or during periods other than normal
business hours or both, then

                                       11


<PAGE>




such excess services shall be supplied at the expense of the Tenant, pursuant to
terms, conditions and costs established by the Landlord in its sole discretion.
Should Tenant require heating and cooling services beyond the hours stipulated
in Section 11(a), Landlord will furnish such additional service at the
then-prevailing hourly rate, as established by Landlord from time to time,
provided that Tenant gives Landlord no less than twenty-four (24) hours advance
written notice of the need therefor.

      (c) Interruption or Reduction of Service. In no event shall Landlord be
liable to Tenant for any interruption or failure in the supply of any utilities
to the Leased Premises and the Building. Landlord reserves the right to
interrupt service of the heat, plumbing, air conditioning, cooling, electric,
and sewer and water systems, when necessary, by reason of accident, or of
repairs, alterations or improvements which in the judgment of Landlord are
desirable or necessary to be made, until such repairs, alterations or
improvements shall have been completed; and Landlord shall have no
responsibility or liability for failure to supply heat, plumbing, air
conditioning, cooling, electric, and sewer and water service, or other service
or act for the benefit of Tenant, when prevented from so doing by strikes,
accidents or by any other causes beyond Landlord's reasonable control, or by
orders or regulations of any federal, state, county, or municipal authority, or
by any failure to receive suitable fuel supply, or inability despite exercise of
reasonable diligence to obtain the regularly-used fuel or other suitable
substitute; and Tenant agrees that Tenant shall have no claim for damages nor
shall there be any abatement of Base Annual Rent in the event that any of said
systems or service shall be discontinued or shall fail to function for any
reason. If any public utility supplying any utility to the Building, or any law,
order or regulation of any federal, state, county or municipal authority
requires that Landlord or Tenant must reduce or maintain a certain level of
consumption of electricity or any other utility or interior temperature for the
Leased Premises or the Building, which affects the normal business hours or the
provision of any utility the Leased Premises or the Building, Landlord and
Tenant shall each adhere to and abide by such requirement without any reduction
in rent or in any of Tenant's other obligations hereunder. Landlord's obligation
to supply heat and air conditioning are subject to applicable laws and
regulations as to energy conservation and other restrictions.

       (d)    Excessive Electrical Usage.

              (i) Tenant will not install or operate in the Leased Premises any
heavy duty electrical equipment or machinery, without obtaining the prior
written consent of Landlord, which consent shall not be unreasonably withheld.
Landlord may require, as a condition of its consent to the installation of such
equipment or machinery, payment by Tenant, as Additional Rent, for such excess
consumption of electricity as may be occasioned by the operation of said
equipment or machinery. Landlord may make periodic inspections of the Leased
Premises at reasonable times to determine that Tenant's electrically operated
equipment and machinery complies with the provisions of this Section and Section
11(e).

              (ii) Landlord shall have the right to require that one or more
separate meters or submeters be installed to record the consumption or use of
electricity, or to cause a reputable independent electrical engineer to survey
and determine the quantity of electricity consumed by such excessive use. The
cost of any such survey or meters and of installation, maintenance and repair
thereof shall be paid by Tenant. Tenant agrees to pay Landlord (or the utility
company, if direct service is provided by the utility company), promptly upon
demand therefor, for all such electricity consumption as shown by said meters,
or a flat monthly charge determined

                                       12


<PAGE>




by the survey, as applicable, at the rates charged for such service by the local
public utility company.

      (e) Excessive Heat Generation. Landlord shall not be liable for its
failure to maintain comfortable atmospheric conditions in all or any portion of
the Leased Premises, due to heat generated by any equipment or machinery
installed by Tenant (with or without Landlord's consent) that exceeds
generally-accepted engineering design practices for normal office purposes. If
Tenant desires additional cooling to offset excessive heat generated by such
equipment or machinery, Tenant shall pay for auxiliary cooling equipment and its
operating costs, including, without limitation, electricity, gas, oil and water,
or for excess electrical consumption by the existing cooling system, as
appropriate.

      (f) Security. Any security measures that Landlord may undertake are for
protection of the Building only and shall not be relied upon by Tenant to
protect Tenant, its property, its employees and/or their property.

12. Landlord's Right of Entry. Landlord, its agents, employees and contractors
shall have the right to enter the Leased Premises at all reasonable times,
including emergencies determined by Landlord, (a) to make inspections or to make
repairs, replacements and improvements to Leased Premises or other premises as
Landlord may deem necessary or reasonably desirable to the Premises or to any
other portion of the Building or which Landlord may elect to perform; (b) to
perform nightly cleaning of the Leased Premises; (c) to exhibit the Leased
Premises to prospective purchasers at any reasonable time, or to prospective
tenants during the last one hundred and eighty (180) days of the Lease Term; and
(d) for any purpose whatsoever relating to the safety, protection or
preservation of the Building. Such entry by Landlord shall be, whenever
reasonably possible, during normally business hours, except in cases of
emergency. Landlord shall use reasonable best efforts to minimize interference
to Tenant's business when making repairs, but, unless otherwise agreed with
Tenant, Landlord shall not be required to perform the repairs at any time other
than during normal working hours. The right and authority hereby reserved do not
impose, no does the Landlord assume by reason thereof, any responsibility or
liability whatsoever for the care, maintenance or supervision of the Leased
Premises or any pipes, fixtures, appliances or appurtenances therein contained
or therewith in any manner connected.

13.   Maintenance and Repairs.

       (a) Landlord Responsibilities. Landlord shall make structural repairs to
the Leased Premises necessary for safety and tenantability, and shall maintain
and repair all Building equipment serving the Leased Premises and all exterior
plate glass in the Leased Premises, and the cost of all such repairs or
maintenance shall be included in Basic Operating Expenses. Tenant waives the
right to make repairs at Landlord's expense under any law, statute or ordinance
now or hereafter in effect. Landlord reserves the right at any time and from
time to time, as often as Landlord deems desirable, without the same
constituting an actual or constructive eviction and without incurring any
liability to Tenant or otherwise affecting Tenant's obligations under this
Lease, to make changes, alterations, additions, improvements, repairs,
relocations or replacements in or to the Building and the fixtures and equipment
thereof. Landlord reserves the right from time to time to install, use,
maintain, repair and replace pipes, ducts, conduits, wires and appurtenant
meters and equipment for service to other parts of the Building, above the
ceiling surfaces, below the floor surfaces, within the walls and in the central
core areas, and to relocate any pipes, ducts, conduits wires and appurtenant
meters and

                                       13


<PAGE>




equipment included in the Leased Premises which are located in the Leased
Premises or located elsewhere outside the Leased Premises. Landlord shall use
reasonable efforts not to disturb Tenant's business operations when making
repairs to the Leased Premises or the Building. Nothing contained herein shall
be deemed to relieve Tenant of any duty, obligation or liability with respect to
making any repair, replacement or improvement or complying with any law, order
or requirement of any government or other authority and nothing contained herein
shall be deemed or construed to impose upon Landlord any obligation,
responsibility or liability whatsoever, for the care, supervision or repair of
the Building, or any part thereof, other than as expressly provided in this
Lease.

      (b) Tenant Responsibilities. Tenant will keep the Leased Premises and the
fixtures and equipment therein in good order and condition, will take good care
thereof and will suffer no waste or damage thereto. Tenant will promptly repair
at its own expense any damage to the Leased Premises caused by bringing into the
premises any property for Tenant's use or by the installation or removal of such
property, regardless of fault or by who such damage shall be caused, unless
caused by Landlord, its agents, employees or contractors; and, in default of
such repairs by Tenant, Landlord shall make the same and Tenant agrees to pay
the costs thereof to Landlord promptly upon Landlord's demand therefor. At the
expiration or other termination of the Lease Term, Tenant will surrender the
Leased Premises broom clean and in the same order and condition in which they
were on the Rent Commencement Date, ordinary wear and tear excepted. All repairs
and maintenance required to be performed by Tenant shall be made or performed
immediately upon the occurrence of the necessity therefor, and shall be made or
performed in a first class manner, using first class materials, by a contractor
approved by Landlord and bonded unless waived by Landlord, and shall be made or
performed in accordance with (i) all laws and all applicable governmental codes
and requirements, and (ii) insurance requirements. Maintenance and repair of
equipment such as kitchen fixtures, auxiliary air-conditioning equipment,
private bathroom fixtures and any other type of special equipment, together with
related plumbing or electrical services, whether installed by Tenant or by
Landlord on behalf of Tenant, shall be the sole responsibility of Tenant, and
Landlord shall have no obligation in connection therewith. If Tenant refuses or
neglects to promptly commence and complete repairs or maintenance necessary to
satisfy the provisions of this Section, the Landlord may, but shall not be
required to, make and complete said repairs or maintenance and Tenant shall pay
the cost therefor (including overhead) to Landlord upon demand, as Additional
Rent.

14.   Common Areas.

       (a) Common Areas Defined. In this Lease, "common areas" means all areas,
facilities and improvements provided, from time to time, in the Building for the
mutual convenience and use of tenants or other occupants of the Building, their
respective agents, employees, and invitees and shall include, if provided, but
shall not be limited to, the lobbies and hallways, the public restrooms, the
parking areas and facilities, access roads, driveways, retaining walls,
sidewalks, walkways, landscaped areas, and exterior lighting facilities.

      (b) Landlord's Control. Landlord shall, as between Landlord and Tenant, at
all times during the term of the Lease have the sole and exclusive control,
management and direction of the common areas, and may at any time and from time
to time during the term exclude and restrain any person from use or occupancy
thereof, excepting, however, Tenant and other tenants of Landlord and bona fide
invitee of either who make use of said areas in accordance with the rules and
regulations established by

                                       14


<PAGE>




Landlord from time to time with respect thereto. The rights of Tenant in and to
the common areas shall at all times be subject to the rights of others to use
the same in common with Tenant, and it shall be the duty of Tenant to keep all
of said areas free and clear of any obstructions created or permitted by Tenant
or resulting from Tenant's operation. Landlord may at any time and from time to
time close all or any portion of the common areas to make repairs or changes or
to such extent as may, in the opinion of Landlord, be necessary to prevent a
dedication thereof or the accrual of any rights to any person or to the public
therein, to close temporarily any or all portions of the said areas to
discourage noncustomer parking, and to do and perform such other acts in and to
said areas as, in the exercise of good business judgment, Landlord shall
determine to be advisable with a view to the improvement of the convenience and
use thereof by tenants, their employees, agents, and invites.

      (c) Changes and Additions to the Building, Additional Construction.
Landlord hereby reserves the right at any time to make alterations or additions
to the Building, as well as in or to the street entrances, halls, passages,
stairways and other common facilities thereof. Tenant agrees that Landlord shall
at all times have the right and privilege of determining the nature and extent
of the common areas, and of making such changes, rearrangements, additions or
reductions therein and thereto from time to time which in its opinion are deemed
to be desirable and for the best interest of all persons using the common areas
or which are as a result of any federal, state or local environmental protection
or other law, rule, regulation, guideline or order. The purpose of the floor
plan attached hereto as Exhibit A is to show the approximate locational
relationship of the Leased Premises to other units in the Building and the
common areas as of the Rent Commencement Date. Nothing described in Exhibit A
shall limit or prevent Landlord from effecting any change or alteration to the
Building or the land upon which it is built as described in this paragraph.

      (d) Parking. Tenant shall have the right to utilize the Building's parking
facilities on a nonexclusive basis with other tenants of the Building, upon such
reasonable terms and conditions as may from time to time be established by
Landlord. Landlord reserves the right in its absolute discretion to determine
whether the parking facilities are becoming crowded and to allocate and assign
parking spaces among Tenant and the other tenants. Tenant shall not use parking
areas for the overnight storage of vehicles, other than Tenant-owned corporate
vehicles which Landlord and Tenant have previously agreed will be regularly
parked overnight at the Building. It is understood and agreed that Landlord
assumes no responsibility, and shall not be held liable, for any damage or loss
to any automobiles parked in the parking facilities or to any personal property
located therein, or for any injury sustained by any person in or about the
parking facilities.

15.   Surrender and Inspection.

      (a) Surrender. Upon the Expiration Date or other termination of the term
of this Lease, Tenant shall quit and surrender the Leased Premises to the
Landlord in as good order and condition as when received, ordinary wear and tear
excepted, and Tenant shall remove all of its property from the Leased Premises
by the Expiration Date or other termination of this Lease, all to the reasonable
satisfaction of the Landlord. Tenant's obligation to observe or perform this
covenant shall survive the expiration or other termination of this Lease.

      (b) Inspection. Tenant shall have the right to be present at time of final
inspection of the Leased Premises to determine if any damages were done thereto,
if Tenant notifies Landlord by certified mail of its intention to move, date of
moving

                                       15


<PAGE>




and new address. The notice of Tenant's desire to be present at the final
inspection of the Leased Premises shall be given at least fifteen (15) days
prior to the date of moving. Upon receipt of such notice, Landlord shall notify
Tenant of time and date when the Leased Premises are to be inspected. The
inspection shall occur within five (5) days before or five (5) days after
Tenant's date of moving, said inspection date to be designated by Landlord.
Tenant shall be deemed to have been advised of its rights under this paragraph
by execution of this Lease.

      (c) Fixtures and Personal Property Remaining. If Tenant does not remove
Tenant's furniture, equipment, machinery, trade fixtures, floor coverings and
all other items of personal property of every kind and description from the
Leased Premises prior to the Expiration Date, then Tenant shall be conclusively
presumed to have conveyed the same to Landlord under this Lease as a bill of
sale without further payment or credit by Landlord to Tenant.

16. Tenant Holding Over. If Tenant holds possession of the Leased Premises after
the Expiration Date or other termination of this Lease, Landlord shall have the
option, exercisable in writing within thirty (30) days after the date of
termination of aforesaid, to treat Tenant as a trespasser, or as a tenant by the
month. If the Landlord fails to make such election then the Tenant shall be
deemed a tenant by the month, commencing with the first day after the
termination of the Lease at one hundred and fifty percent (150%) the Basic
Monthly Rent paid during the last month of the Term, and upon all the other
terms of this Lease, including the provisions of this paragraph. Said holdover
term shall terminate upon thirty (30) days notice from one party to the other.
Nothing contained herein shall be construed within said thirty (30) days after
the date of Lease termination as aforesaid as a consent by Landlord to the
occupancy or possession of the Leased Premises by Tenant after the termination
of the Lease, and Landlord, upon said termination, if Landlord elects to treat
Tenant as a trespasser, shall be entitled to the benefit of all public general
or public laws relating to the speedy recovery of the possession of land and
tenements held over by Tenant, whether now or hereafter in force and effect. If
Tenant fails to surrender the Leased Premises upon the expiration or other
termination of this Lease despite demand to do so by Landlord, Tenant shall
indemnify and hold Landlord harmless from all injury, loss, claims, expenses and
liability, including without limitation, any claim made by any succeeding tenant
and any attorneys' fees, founded on or resulting from such failure to surrender.

17. Covenant Against Assignment and Subletting. Tenant shall not assign,
mortgage or encumber this Lease, or any right hereunder, nor sublet the Leased
Premises or any part thereof, nor permit the Leased Premises to be used by
others without the prior written consent of Landlord, which consent shall not be
unreasonably withheld. Notwithstanding the foregoing, however, Tenant may sublet
this lease to an affiliate, parent or subsidiary of Tenant without Landlord's
consent. If Tenant, or any Guarantor, is a corporation, unincorporated
association or partnership, then the transfer, assignment or hypothecation of
any stock or interest in such corporation, association or partnership so as to
result in a change in the control thereof by the person, persons or entities
owning a controlling interest therein as of the date of this Lease, without the
prior written consent of Landlord as described above, shall be deemed an
assignment made in breach of this covenant. Landlord's consent in any specific
instance to any assignment, mortgage, encumbrance, subletting or use of the
Leased Premises and its collection and acceptance of rent from any such approved
assignee, subtenant or other occupant shall neither constitute a waiver of the
provisions of this paragraph, nor be construed as permission for any subsequent
assignment, mortgage, encumbrance, subletting or use without compliance with
this paragraph. Without the prior written consent of Landlord, this Lease and
the

                                       16


<PAGE>




interest of Tenant, or any assignee of Tenant, shall not pass by operation of
law, nor shall it be subject to garnishment or sale under execution in any suit
or proceeding which may be brought against or by Tenant, or any assignee of
Tenant. No permitted assignment or sublease or collection of rent from an
approved assignee or subtenant shall relieve Tenant of its obligations
hereunder. Landlord shall have the right at any time to assign this Lease, in
whole or in part, to any third party.

18.   Bankruptcy.

       (a) The following shall be Events of Bankruptcy under this Lease: (1)
Tenant's or any guarantor of Tenant's obligations under this Lease ("Tenant's
Guarantor") becoming insolvent, as that term is defined in Title 11 of the
United States Code (the "Bankruptcy Code"), or under the insolvency laws of any
state, district, commonwealth or territory of the United States (the "Insolvency
Laws"); (2) the appointment of a receiver or custodian for any or all of
Tenant's or Tenant's Guarantor property or assets, or the institution of a
foreclosure action upon any of Tenant's or Tenant's Guarantor's real or personal
property; (3) the filing of a voluntary petition under the provisions of the
Bankruptcy Code or Insolvency Laws; (4) the filing of an involuntary petition
against Tenant or Tenant's Guarantor as the subject debtor under the Bankruptcy
Code or Insolvency Laws, which either (A) is not dismissed within thirty(30)
days of filing, or (B) results in the issuance of an order for relief against
the debtor; or (5) Tenant's or Tenant's Guarantor's making or consenting to an
assignment for the benefit of creditors or a common law composition of
creditors; or (6) if a corporate reorganization of Tenant or an agent with its
creditors shall be approved by a court under the Federal Bankruptcy Act.

      (b) Upon occurrence of an Event of Bankruptcy, Tenant shall be deemed to
have breached a material covenant of this Lease and Landlord shall have all
rights and remedies available to Landlord pursuant to Section 20; provided,
however, that while a case in which Tenant is the subject debtor under the
Bankruptcy Code is pending, Landlord shall not exercise its rights and remedies
pursuant to Section 20 so long as (1) the Bankruptcy Code prohibits the exercise
of such rights and remedies, and (2) Tenant or its Trustee in Bankruptcy
(hereinafter referred to as "Trustee") (i) cures all defaults under this Lease,
(ii) compensates Landlord for monetary damages incurred as a result of such
defaults, (iii) provides adequate assurance of future performance on the part of
Tenant as debtor in possession or on the part of the assignee tenant, and (iv)
complies with all other requirements of the Bankruptcy Code.

19. Default. Each of the following shall be deemed a default by Tenant and a
breach of this Lease:

      (a)     An Event of Bankruptcy as defined in Section 18;

      (b)     An assignment or encumbrance of Tenant's interest in this Lease or
the Leased Premises or a subletting of any part of the Leased Premises in
violation of Section 17;

      (c)     The suspension of business by Tenant;

      (d)     The filing of a tax lien against any property of Tenant;

      (e)     Discontinuance by Tenant of the conduct of its business in the
Leased Premises, or an abandonment or vacation of the Leased Premises by Tenant
for a period of sixty (60) days or more;

                                       17


<PAGE>




      (f) A failure by Tenant to pay Minimum Annual Rent or Additional Rent when
due, where such failure continues for ten (10) days after notice thereof from
Landlord, provided, however, that Landlord need provide such notice no more than
three (3) times in any twelve (12) month period, and the fourth such default in
a twelve month period shall be deemed a default by Tenant without such notice
from Landlord;

      (g) A failure by Tenant to observe and perform any other term, covenant,
agreement or condition of this Lease to be observed or performed by Tenant,
where such failure continues for ten (10) business days after notice thereof
from Landlord, provided, however, that if the nature of the default is such that
the same cannot be reasonably be cured within the ten (10) business day period
allowed, Tenant shall not be deemed to be in default if Tenant shall, within
such ten (10) business day period, commence to cure and there after diligently
prosecute the same to completion. Nonetheless, Tenant will be deemed to be in
default if the same default is not cured within sixty (60) days after that
reasonable effort commences. Landlord shall not, however, be required to give
such notice if Tenant's failure to perform constitutes a noncurable breach of
this Lease. The notice required by this Paragraph is intended to satisfy any and
all notice requirements imposed by law on Landlord and is not in addition to any
such requirement;

      (h) Any material misrepresentation by Tenant to Landlord in connection
with the negotiation or execution of this Lease;

      (i) A default by Tenant under any other lease or sublease for any other
space in the Building, which has resulted in the termination of said lease;

      (j) Failure by any surety or guarantor of this Lease to comply with all
the provisions of the suretyship or guaranty agreement; or

      (k) The merger of any corporate surety or corporate guarantor of this
Lease with another entity, or the liquidation or dissolution of such surety or
guarantor or the change of control of such surety or guarantor caused by the
transfer of stock of such surety or guarantor, except by reason of the death of
any shareholder thereof.

20. Landlord's Rights Upon Tenant's Default. Upon default by Tenant of any of
the terms or covenants of this Lease, then in addition to any other remedies
available to Landlord herein at law or in equity, Landlord shall be entitled to
remedy such default as follows:

      (a) Re-Entry. Landlord shall have the right, immediately or at any time
thereafter, without further notice to Tenant (unless otherwise provided herein),
to enter the Leased Premises (breaking open locked doors, if necessary, and
using as much reasonable force as necessary to effect the manner thereof),
without terminating this Lease or being guilty of trespass, and do any and all
acts as Landlord may deem necessary, proper or convenient to cure such default,
for the account and at the expense of Tenant, and Tenant agrees to pay to
Landlord as Additional Rent all damage and/or expense incurred by Landlord in so
doing, including interest at the Penalty Rate, from the due date until the date
payment is received by Landlord. Landlord shall not be liable for any loss,
injury or damage resulting in any way from such action by Landlord.

      (b) Termination. Landlord shall have the right to terminate this Lease and
Tenant's right to possession of the Leased Premises and, with or without legal
process, take possession of the Leased Premises and remove Tenant, any occupant
and

                                       18


<PAGE>




any property therefrom, using such force as may be necessary, without being
guilty of trespass and without relinquishing any rights of Landlord against
Tenant. Landlord shall be entitled to recover damages from Tenant in an amount
equal to the amount herein covenanted to be paid as Minimum Annual Rent during
the remainder of the Lease Term, said Minimum Annual Rent and Additional Rent
for the full term then remaining having been fully accelerated at the option of
Landlord, together with (i) all expenses of any proceedings (including, but not
limited to, legal expenses and reasonable attorney's fees) which may be
necessary in order for Landlord to recover possession of the Leased Premises,
(ii) the expenses of the re-renting of the Leased Premises (including, but not
limited to, any commissions paid to any real estate agent, advertising expense
and the costs of such alterations, repairs, replacements and decoration or
re-decoration as Landlord, in its sole judgment, considers advisable and
necessary for the purpose of re-renting the Leased Premises), and (iii) interest
computed at the Penalty Rate from the due date until paid; provided, however,
that there shall be credited against the amount of such damages all amounts
received by Landlord from such re-renting of the Leased Premises and such
amounts shall be refunded to Tenant.

      Landlord shall use its best efforts to re-rent the Premises, but Landlord
has no obligation to favor the Leased Premises over any other space available
for lease in the Building, and Landlord shall in no event be liable in any way
whatsoever for failure to re-rent the Leased Premises or, in the event that the
Leased Premises are re-rented, for failure to collect the rent thereof under
such re-renting. No act or thing done by Landlord shall be deemed to be an
acceptance of a surrender of the Leased Premises, unless Landlord shall execute
a written agreement of surrender with Tenant. Tenant's liability hereunder shall
not be terminated by the execution of a new lease of the Leased Premises by
Landlord. In the event Landlord does not exercise its option to accelerate the
payment of Minimum Annual Rent and Additional Rent as provided hereinabove, then
Tenant agrees to pay to Landlord, upon demand, the amount of damages herein
provided after the amount of such damages for any month shall have been
ascertained; provided, however, that any expenses incurred by Landlord shall be
deemed to be a part of the damages for the month in which they were incurred.
Separate actions may be maintained each month or at other times by Landlord
against Tenant to recover the damages then due, without waiting until the end of
the term of this Lease to determine the aggregate amount of such damages. Tenant
hereby expressly waives any and all rights of redemption granted by or under any
present or future laws in the event of Tenant being evicted or being
dispossessed for any cause, or in the event of Landlord obtaining possession of
the Leased Premises by reason of the violation by Tenant of any of the covenants
and conditions of this Lease.

      (c) Distress. Upon any default by Tenant in the payment of Minimum Annual
Rent or Additional Rent, Landlord shall have the right, without notice, fifteen
(l5) days after payment of such sum was due, to institute an action of distress
therefor, and, upon distress, in Landlord's discretion, this tenancy shall
terminate. In the event of such termination, the provisions of Section 20(b)
shall be applicable.

      (d) Lien for Rent. Upon any default by Tenant in the payment of Minimum
Annual Rent or Additional Rent, Landlord shall have a lien upon the property of
Tenant in the Leased Premises for the amount of any unpaid Minimum Annual Rent
or Additional Rent. In such event, Tenant shall not remove any of Tenant's
property from the Leased Premises except with the prior written consent of
Landlord, and Landlord

                                       19


<PAGE>




shall have the right and privilege, at its option, to take possession of all
property of Tenant in the Leased Premises, to store the same on the Leased
Premises, or to remove it and store it in such place as may be selected by
Landlord, at Tenant's risk and expense.

      (e) No Future Lease Rights. If at any time during the term of this Lease
Tenant has been in default beyond Tenant's right to cure period, then,
regardless of whether Tenant is in default at the time of any option or future
right, all of Tenant's present and future rights to this Lease are then
terminated when the default occurs.

      (f) Utilities and Services. Upon any default by Tenant, Landlord may
immediately cease to provide all utilities and services to the Leased Premises
as provided under Section 11 herein.

      (g) Landlord's Remedies Cumulative. All rights and remedies of Landlord
herein enumerated shall be cumulative, and none shall exclude any other right or
remedy allowed by law. For the purposes of any suit brought or based hereon,
this Lease shall be construed to be a divisible contract, to the end that
successive actions may be maintained on this Lease as successive periodic sums
mature hereunder.

21.   Lender Requirements.

       (a) Subordination. Tenant agrees that this Lease is subject and
subordinate to any and all ground or underlying leases and to the lien of any
first mortgages or deeds of trust now on or which at any time may be made a lien
upon the Building, or any part thereof, and to all advances made or hereafter to
be made upon the security thereof. This subordination provision shall be
self-operative and no further instrument of subordination shall be required.
Tenant agrees to execute and deliver, upon request, within five (5) days demand
by Landlord, such further instrument or instruments confirming this
subordination as shall be desired by Landlord or by any mortgagee or proposed
mortgagee; and Tenant hereby constitutes and appoints Landlord as Tenant's
attorney-in-fact to execute any such instrument or instruments. Upon Tenant's
written request, Landlord shall use its best efforts to acquire from any such
mortgagee an agreement that any proceeding to foreclose, sell or any other
action taken under the mortgage shall not affect Tenant's rights to continue to
occupy the Leased Premises and exercise and enjoy all of its rights hereunder so
long as Tenant complies with the terms and provisions of this Lease, and
continues to make the payments required here-under to the appropriate designated
party, provided, Landlord's failure to acquire such an agreement shall not
mitigate Tenant's obligations hereunder. Tenant further agrees that, at the
option of the holder of any first mortgage or of the trustee under any first
deed of trust, this Lease may be made superior to said first mortgage or first
deed of trust by the insertion therein of a declaration that this Lease is
superior thereto.

      (b) Attornment. In the event any proceedings are brought for the
foreclosure of, or in the event of exercise of the power of sale under, any deed
to secure debt given by Landlord and covering the Leased Premises, Tenant shall
attorn to the purchaser upon any such foreclosure or sale and recognize such
purchaser as the owner and landlord under this Lease.

      (c) Financing. This Lease is subject to the approval of the mortgage
lender(s) providing mortgage financing for the Building, and disapproval of this
Lease by any such mortgage lender shall result in termination of this Lease. In
the event that any mortgage lender providing mortgage financing for the Building
requires, as a

                                       20


<PAGE>




condition of such financing, that modifications to this Lease be obtained, and
provided that such modifications (i) are reasonable, (ii) do not adversely
affect Tenant's use of the Leased Premises as herein permitted, (iii) do not
materially alter the approved plans for the Basic Work and Additional Work and
(iv) do not increase the rentals and other sums required to be paid by Tenant
hereunder, then Landlord may submit to Tenant a written amendment to this Lease
incorporating such required modifications, and, in the event Tenant does not
execute and return to Landlord such written amendment within ten (10) days after
the same has been submitted to Tenant, then Landlord shall thereafter have the
right, at its sole option, to terminate this Lease. Such option shall be
exercisable by Landlord giving Tenant written notice of termination, immediately
whereupon this Lease shall be terminated, and money or security therefor
deposited by Tenant with Landlord shall be returned to Tenant, and both Landlord
and Tenant shall thereupon be relieved from any and all further liability or
obligation hereunder.

       (d) Financial Statements. Tenant agrees, not more often than once per
calendar year, upon written notice by Landlord, to deliver to Landlord such
financial statements detailing its profits and losses, certified by a duly
authorized officer of Tenants if Tenant.

22. Estoppel Certificates. Tenant agrees, at any time and from time to time,
upon not less than ten (10) days prior written notice by Landlord, to execute,
acknowledge and deliver to Landlord a written estoppel certificate (i)
certifying that this Lease is unmodified and in full force and effect (or if
there have been modifications, stating the nature of same), (ii) stating the
Rent Commencement Date of the Lease Term, (iii) stating the amounts of Minimum
Annual Rent and Additional Rent and the dates to which the Minimum Annual Rent
and Additional Rent have been paid by Tenant, (iv) stating the amount of any
Security Deposit, (v) stating whether or not to the best knowledge of Tenant,
Landlord is in default in the performance of any covenant, agreement or
condition contained in this Lease, and, if so, specifying each such default of
which Tenant may have knowledge, (vi) stating that Tenant has no right to set
off and no defense against payment of the Minimum Annual Rent or Additional
Rent, (vii) address to which notices to Tenant should be sent. and (viii)
certifying such other matters as may be requested by Landlord. Any such
certificate delivered pursuant hereto may be relied upon by an owner of the
Building, any prospective purchaser of the Building, any mortgagee or
prospective mortgagee of the Building or of Landlord's interest therein, or any
prospective assignee of any such mortgage. Failure to deliver the aforesaid
certificate within the five (5) days shall be conclusive upon Tenant for the
benefit of Landlord and any successor to Landlord that this Lease is in full
force and effect and has not been modified except as may be represented by the
party requesting the certificate. Tenant shall be liable for any loss incurred
by Landlord resulting from Tenant's failure to timely execute and deliver any
estoppel certificate requested by Landlord, and shall reimburse Landlord for the
amount of any such loss upon demand, as Additional Rent.

23. Damage by Fire or Other Casualty. If the Leased Premises, or any other
portion of the Building shall, through no fault of Tenant or Tenant's agents,
servants, employees, customers, contractors, visitors or licensees, be damaged
by fire, the elements, unavoidable accident or other casualty:

      (a) Except as otherwise provided in subparagraph (b) hereof, Landlord, at
Landlord's expense, shall promptly restore the Leased Premises, and Tenant, at
Tenant's sole expense, shall promptly restore all leasehold improvements
installed in the Leased Premises by Tenant or at Tenant's request and its own
furniture, furnishings, trade fixtures and equipment and the rent shall not be
abated. No

                                       21


<PAGE>




penalty shall accrue for reasonable delay which may arise by reason of
adjustment of insurance on the part of Landlord, or on account of labor
problems, or any other cause beyond Landlord's reasonable control. If the damage
or destruction is such as to make the Leased Premises or any substantial part
thereof untenantable (in Landlord's judgment), and provided that such damage or
destruction is not due in whole or part to the act or omission of Tenant or
Tenant's agents, employees or invites, the Minimum Annual Rent shall abate
proportionately (based on proportion of the number of square feet rendered
untenantable to the total number of square feet of the Leased Premises), from
the date of the damage or destruction until the date the Leased Premises has
been restored by Landlord.

      (b) If the Leased Premises are substantially damaged or are rendered
substantially untenantable by fire or other casualty, or if Landlord's architect
certifies that the Leased Premises cannot be repaired within one hundred twenty
(120) working days of normal working hours, said period commencing with the
start of the repair work, or if Landlord shall decide not to restore or repair
the same, or if more than fifty percent (50%) of the gross leasable area of the
Building is rendered untenantable (even if the Leased Premises is undamaged) or
if Landlord shall decide to demolish the Building or not to rebuild it, then
Landlord may, within ninety (90) days after such fire or other casualty,
terminate this Lease by giving Tenant a notice in writing of such decision, and
thereupon the term of this Lease shall expire on the date specified in such
notice, or, if not date is so specified, by lapse of time upon the third day
after such notice is given, and Tenant shall vacate the Leased Premises and
surrender the same to Landlord. Upon the termination of this Lease under the
conditions hereinbefore provided, Tenant's liability for Minimum Annual Rent and
Additional Rent shall cease as of the day following the casualty.

      (c) The proceeds payable under all casualty insurance policies maintained
by Landlord on the Leased Premises shall belong to and be the property of
Landlord, and Tenant shall not have any interest in such proceeds. Tenant agrees
to look to Tenant's casualty insurance policies for the restoration and
replacement of the leasehold improvements installed in the Leased Premises by
Tenant or at Tenant's request and Tenant's fixtures, equipment and furnishings
in the Leased Premises, and in the event of termination of this Lease, for any
reason, following any such damage or destruction, Tenant shall promptly assign
to Landlord or otherwise pay to Landlord, upon Landlord's request, the proceeds
of said insurance and such other additional funds so that the total amount
assigned and/or paid by Tenant to Landlord shall be sufficient to restore
(whether or not any such restoration is actually to occur) all improvements,
fixtures, equipment and furnishings (excepting only Tenant's trade fixtures and
equipment) existing in the Leased Premises immediately prior to such damage or
destruction.

      (d) Notwithstanding anything to the contrary in this Section 23 or in any
other provision of this Lease, any obligation (under this Lease or otherwise) of
Landlord to restore all or any portion of the Leased Premises shall be subject
to Landlord's receipt of approval of the same by the mortgagee(s) of Landlord
(and any other approvals required by applicable laws), as well as receipt from
any such mortgagee(s) of such fire and other hazard insurance policy proceeds as
may have been assigned to any such mortgagee; it being agreed that if Landlord
has not received such approval(s) and proceeds within one hundred and eighty
(180) days after any such casualty, then Landlord shall have the option to
terminate this Lease, at any time thereafter, upon notice to Tenant.

                                       22


<PAGE>




24. Condemnation. In the event the whole or a substantial part of the Leased
Premises or the Building shall be taken for any public or quasi-public purpose
by any lawful power or authority by exercise of the right of appropriation,
condemnation or eminent domain, or sold to said authority to prevent such taking
(collectively referred to herein as a "taking"), Landlord shall have the right
to terminate this Lease effective as of the date possession is required to be
surrendered to said authority, and the Minimum Annual Rent and Additional Rent
shall be apportioned as of the date. For purposes of this section, a substantial
part of the Leased Premises or the Building shall be considered to have been
taken if, in Landlord's opinion, the taking shall render it commercially
undesirable for Landlord to permit this Lease to continue or to continue
operating the Leased Premises or the Building. Tenant shall not assert any claim
against Landlord or the taking authority for any compensation arising out of or
related to such taking and Landlord shall be entitled to receive the entire
amount of any award without deduction for any estate or interest of Tenant. If
Landlord does not elect to terminate this Lease, the Minimum Annual Rent and
Additional Rents shall be adjusted (based on the ratio that the number of square
feet of rentable area taken from the Leased Premises bears to the number of
rentable square feet in the Leased Premises immediately prior to such taking) as
of the date possession is required to be surrendered to said authority. Nothing
contained in this section shall be deemed to give Landlord any interest in any
award made to Tenant for the taking of personal property and fixtures belonging
to Tenant, as long as such award is made in addition to and separately stated
from any award made to Landlord for the Leased Premises or the Building.
Landlord shall have no obligation to contest any taking.

25. Landlord's Reserved Rights. The Landlord reserves the following rights:

      (a) To decorate, remodel, repair, alter or otherwise prepare the Leased
Premises for reoccupancy during the last ninety (90) days of the Lease Term, if
during or prior to that time Tenant vacates the Leased Premises; and

      (b) To show the Leased Premises to prospective tenants or brokers during
the last one hundred eighty (180) days of the term of this Lease, and to show
the Leased Premises to prospective purchasers, mortgagee, or assignee of any
mortgage on the Building at all reasonable times provided that reasonable prior
notice is given to Tenant in each case and that Tenant's use and occupancy of
the Leased Premises shall not be materially inconvenienced by any such action of
Landlord.

26.   Landlord and Tenant Liability.

       (a) Landlord's Liability. It is understood and agreed that Landlord is a
Maryland limited partnership and/or joint venture and that no partner of the
partnership, as may now or hereinafter be constituted, shall have liability to
Tenant or any person claiming under, by or through Tenant on any action, claim,
suit or demand brought pursuant to the terms and conditions of this Lease or
arising out of the occupancy by the Tenant of the Leased Premises. Landlord, or
its agents, shall not be responsible or liable to the Tenant or its agents,
employees, contractors, customers or other visitors for any injury or damage
resulting from acts or omissions of persons occupying property adjoining the
Leased Premises, or any part of the Building of which the Leased Premises are a
part, or for any injury or damage to persons or property resulting from fire,
explosion, falling plaster, steam, gas, electricity, water, rain, dampness or
snow or leaks from or through any part of the Leased Premises or the Building,
including the roof, or from the pipes,

                                       23


<PAGE>




conduits, appliances or plumbing works, or from the roof, street or subsurface
or from any other place or by dampness or by any other cause of whatsoever
nature, unless caused by or due to the gross negligence of Landlord, its agents,
servants, or employees. All personal property and equipment located in the
Leased Premises shall be at the risk of Tenant.

      (b) Tenant's Liability. Tenant shall reimburse Landlord for all expense,
damages or fines, incurred or suffered by Landlord by reason of any breach,
violation or nonperformance by Tenant, or its agents, servants, or employees, of
any material covenant or material provision of this Lease or the Rules and
Regulations promulgated by Landlord hereunder from time to time, or by reason of
damage to persons or property caused by moving property of or for Tenant in or
out of the Building, or by the installation or removal of furniture or other
property of or for Tenant, or by reason of or arising out of the carelessness,
negligence or improper conduct of Tenant, or its agents, servants, employees,
invites or licensees in the use or occupancy of the Leased Premises.

      (c) Indemnity. Tenant shall indemnify Landlord and its agents and
employees and save them harmless from and against any and all claims, actions,
damages, liabilities and expenses in connection with loss of life, personal
injury and/or damage to property (i) arising from or out of the occupancy or use
by Tenant of the Leased Premises or any part thereof, or (ii) occasioned wholly
or in part by any act or omission of the Tenant, its agents, contractors,
employees, servants, invites or licensees, whether inside the Leased Premises or
elsewhere in the Building; provided, however, that this indemnification shall
not apply to any such injury, loss, damage or liability arising from any
omission, fault, negligence, or misconduct on the part of the Landlord, its
agents, servants, employees, contractors or licensees. In the event that
Landlord or its agents and employees shall, without fault on its or their part,
be made a party to any litigation commenced by or against Tenant, then Tenant
shall protect and hold the same harmless and shall pay all costs, expenses and
reasonable attorneys' fees incurred or paid in connection with such litigation.

      (d) Criminal Acts of Third Parties. Landlord shall not be liable in any
manner to Tenant, its agents, employees, licensees, invitees or contractors for
any injury or damage to Tenant, Tenant's agents, employees, licensees, invites,
or contractors or their property caused by the criminal or intentional
misconduct of third parties. All claims against Landlord for any such damage or
injury are hereby expressly waived by Tenant, and Tenant hereby agrees to hold
harmless and indemnify Landlord from all such damages and the expense of
defending all claims made by Tenant's agents, employees, licensees, invitees or
contractors arising out of such acts.

27.   Tenant's Insurance.

       (a) Coverages. Tenant shall have issued, pay the premiums therefor, and
maintain in full force and effect during the Lease Term:

              (i) Commercial General Liability. A commercial general liability
insurance policy or policies (providing among other coverages: Blanket
Contractual, Personal Injury, independent Contractors, Products/Completed
Operations Hazard, Automobile Liability/Comprehensive Form, and Workers
Compensation) in which the Landlord (and such additional persons and/or entities
as Landlord may request) and Tenant shall be the insured, naming the Landlord
(and such additional persons and/or entities as Landlord may request) and Tenant
as insured parties in the amount of Two

                                       24


<PAGE>




Million and No/100 Dollars ($2,000,000.00) combined single limit general
liability coverage for bodily injury or property damage, which amount may be
increased from time to time by the Landlord in its reasonable determination;

              (ii) All-Risk Property. All-risk property insurance, including
theft, naming Landlord (and such additional persons and/or entities as Landlord
may request) and Tenant as insured, written at replacement cost value and with
replacement cost endorsement, covering all leasehold improvements installed in
the Leased Premises by Tenant or at Tenant's request and all of Tenant's
personal property in the Leased Premises (including, without limitation,
inventory, trade fixtures, floor coverings, furniture and other property
removable by Tenant under the provisions of this Lease);

              (iii) Workers' Compensation. If and to the extent required by law,
workers' compensation and employer's liability or similar insurance in form and
amounts required by law; and

              (iv) Additional Insurance. Such additional insurance as any
mortgagee of the Building may require.

      (b) Policy Requirements. In the event Tenant shall fail to provide such
insurance, or shall fail to pay the premiums when due, Landlord shall have the
right to cause such insurance to be issued and to pay the premiums therefor, or
any premiums in default, and to collect same as Additional Rent together with
interest at the Penalty Rate on the amount of such premiums from the date of
payment by Landlord until the date of repayment by Tenant. All such policies
shall contain only such reasonable deductible amounts as may be approved in
advance by Landlord and shall contain a provision that Landlord shall receive
not less than thirty (30) days advance notice in writing from the insurance
company of any intention of the insurance company to cancel such policy or
policies. Tenant shall provide written evidence to Landlord of its acquisition
of such policies no later than ten (10) days prior to the commencement of this
Lease and prior to any renewal date of such policies. All policies shall be
carried with an insurance company qualified to do business in the State of
Maryland, and rated A or better by the A.M. Best Company.

      (c) No Limitation of Liability. Neither the issuance of any insurance
policy required under this Lease nor the minimum limits specified herein shall
be deemed to limit or restrict in any way Tenant's liability arising under or
out of this Lease.

      (d) Notice of Fire and Accident. Tenant shall give Landlord immediate
notice in case of fire, theft, or accidents in the Leased Premises, and in case
of fire, theft or accidents in the Building if involving Tenant, its agents,
employees or invitees.

28. Waiver of Subrogation. Landlord and Tenant mutually covenant and agree that
each party, in connection with insurance policies required to be furnished in
accordance with the terms and conditions of this Lease, or in connection with
insurance policies which they obtain insuring such insurable interest as
Landlord or Tenant may have in its own properties, whether personal or real,
shall expressly waive any right of subrogation on the part of the insurer
against the Landlord (and any mortgagee requested by Landlord) or Tenant as the
same may be applicable, which right to the extent not prohibited or violative of
any such policy is hereby expressly waived, and Landlord and Tenant each
mutually waive all right of recovery, claims, losses and/or damages against each
other, their agents, or employees for any

                                       25


<PAGE>




loss, damage or injury of any nature whatsoever to property or person for which
either party is required by this Lease to carry insurance.

29. No Liens Permitted: Discharged. Tenant will not permit to be created or to
remain undischarged any lien, encumbrance or charge (arising out of any work
done or materials or supplies furnished, or claimed to have been done or
furnished, by any contractor, mechanic, laborer or materialman or any mortgage,
conditional sale, security agreement or chattel mortgage, or otherwise by or for
Tenant) which might be or become a lien or encumbrance or charge upon the
Building or any part thereof or the income therefrom. Tenant will not suffer any
other matter or thing whereby the estate, rights and interests of Landlord in
the Building or any part thereof might be impaired. If any lien, or notice of
lien on account of an alleged debt of Tenant or any notice of contract by a
party engaged by Tenant or Tenant's contractor to work on the Leased Premises
shall be filed against the Building or any part thereof, Tenant, within fifteen
(15) days after notice of the filing thereof, will cause the same to be
discharged of record by payment, deposit, bond, order of a court of competent
jurisdiction or otherwise. If Tenant shall fail to cause such lien or notice of
lien to be discharged within the period aforesaid, then, in addition to any
other right or remedy, Landlord may, but shall not be obligated to, discharge
the same either by paying the amounts claimed to be due or by procuring the
discharge of such lien by deposit or by bonding proceedings and in any such
event Landlord shall be entitled, if Landlord so elects, to compel the
prosecution of an action for the foreclosure of such lien by the lienor and to
pay the amount of the judgment in favor of the lienor with interest, costs and
allowances. Any amount so paid by Landlord and all costs and expenses, including
attorneys' fees, incurred by Landlord in connection therewith, shall constitute
Additional Rent payable by Tenant under this Lease and shall be paid by Tenant
to Landlord on demand. Nothing herein contained shall obligate Tenant to pay or
discharge any lien created by Landlord.

30. Signs and Advertisements. Landlord shall provide for Tenant, at Landlord's
expense, a notice in the Building directory, Building street sign, and a sign
for the entrance door to the Leased Premises in the type and manner Landlord
from time to time provides for tenants of the Building. No other sign,
advertisement, notice or any other thing of any kind whatsoever shall be
inscribed, painted, affixed or displayed in or about the Building by Tenant and
if any such sign, advertisement or notice is exhibited, Landlord shall have the
right to remove the same and Tenant shall be liable for any and all expenses
incurred by Landlord for said removal. Tenant agrees to maintain its entrance
door or entry sign in good condition and repair at all times.

31. Notices. All notices to be given under this Lease shall be in writing,
hand-delivered, sent by Federal Express, or mailed by United States Certified or
Registered Mail, postage prepaid. Notices should be delivered as follows:

      (a)     To the Landlord at the address specified in Section 1(a)(18).

      (b)     To the Tenant at the addresses specified in Sections l(a)(17).

Any such notice shall be deemed to be served on the date it is hand-delivered or
delivered by Federal Express, or on the third day after the date on which it is
deposited in the U.S. mails. Landlord and Tenant shall each have the right to
change

                                       26


<PAGE>




the person and/or address to which notices shall be delivered upon written
notice thereof to the other party sent pursuant to the provisions of this
paragraph.

32. Time. Landlord and Tenant acknowledge that time is of the essence in the
performance of any and all obligations, terms, and provisions of this Lease.

33. Postponement of Performance. In the event that either party hereto shall be
delayed or hindered in or prevented from the performance of any act required
hereunder by reason of strikes, labor troubles, inability to procure labor or
materials, failure of power, restrictive governmental laws or regulations,
riots, insurrection, war, acts of God, fire or other casualty or other reason of
a similar or dissimilar nature beyond the reasonable control of the party
delayed in performing work or doing acts required under the terms of this Lease,
then performance of such act shall be excused for the period of the delay and
the period for the performance of any such act shall be extended for a period
equivalent to the period of such delay. The provisions of this paragraph shall
not operate to excuse Tenant from the prompt payment of Minimum Annual Rent or
Additional Rent and shall not operate to extend the term of this Lease. Delays
or failures to perform resulting from lack of funds shall not be deemed delays
beyond the reasonable control of a party.

34. No Waiver. No provision of this Lease shall be deemed to have been waived by
Landlord, unless such waiver be in writing signed by Landlord. No waiver by
Landlord of any breach by Tenant of any of the terms, covenants, agreements, or
conditions of this Lease shall be deemed to constitute a waiver of any
succeeding breach thereof, or a waiver of any breach of any of the other terms,
covenants, agreements, and conditions herein contained.

        No employee of Landlord or of Landlord's agents shall have any authority
to accept the keys of the Leased Premises prior to termination of the Lease, and
the delivery of keys to any employee of Landlord or Landlord's agents shall not
operate as a termination of the Lease or a surrender of the Leased Premises. The
receipt by Landlord of any payment of Minimum Annual Rent or Additional Rent
with knowledge of the breach of any covenant of this Lease shall not be deemed a
waiver of such breach. The failure of Landlord to enforce any of the Rules and
Regulations made a part of this Lease, or hereafter adopted, against Tenant or
any other tenant in the Building shall not be deemed a waiver of any such Rules
and Regulations.

35. Limitation of Landlord's Liability. In consideration of the benefits
accruing hereunder, Tenant and all successors and assigns of Tenant covenant and
agree that in the event of any actual or alleged failure, breach or default
hereunder by Landlord: (a) the sole and exclusive remedy shall be against the
interest of Landlord in the Building of which the Leased Premises are a part;
(b) neither Landlord nor any partner of Landlord shall be personally liable with
respect to any claim arising out of or related to this Lease; (c) no partner of
Landlord shall be sued or named as a party in any suit or action (except as may
be necessary to secure jurisdiction of Landlord); (d) no service of process
shall be made against any partner of Landlord (except as may be necessary to
secure jurisdiction of Landlord); (e) any judgment granted against any partner
of Landlord may be vacated and set aside at any time as if such judgment had
never been granted; and (f) these covenants and agreements are enforceable both
by Landlord and also by any partner of Landlord.

                                       27


<PAGE>




36. Transfer of the Building. In the event of the sale or other transfer of
Landlord's right, title and interest in the Leased Premises or the Building
(except in the case of a sale-leaseback financing transaction in which Landlord
is the lessee), Landlord shall transfer and assign to such purchaser or
transferee all amounts of pre-paid Minimum Annual Rent, and Landlord thereupon
and without further act by either party hereto shall be released from all
liability, obligations, and covenants, express or implied, hereunder derived
from this Lease arising out of any act, occurrence or omission relating to the
Leased Premises or this Lease occurring after the consummation of such sale or
transfer, provided that the transferee shall assume all of Landlord's
obligations hereunder from the date of such transfer. Tenant shall have no right
to terminate this Lease nor to abate Minimum Annual Rent nor to deduct from, nor
set-off, nor counterclaim against Minimum Annual Rent because of any sale or
transfer (including, without limitation, any sale-leaseback) by Landlord or its
successors or assigns. This lease shall not be affected by any such sale, and
Tenant agrees to attorn to the purchaser or transferee. Upon any sale or other
transfer as above provided (other than a sale-leaseback), or upon any assignment
of Landlord's interest herein, it shall be deemed and construed conclusively,
without further agreement between the parties, that the purchaser or other
transferee or assignee has assumed and agreed to perform the obligations of
Landlord thereafter accruing.

37. Waiver of Counterclaim and Trial by Jury. Landlord and Tenant waive their
right to trial by jury in any action, proceeding or counterclaim brought by
either of the parties hereto against the other (except for personal injury or
property damage) on any matters whatsoever arising out of or in any way
connected with this Lease, the relationship of Landlord and Tenant, Tenant's use
of or occupancy of the Leased Premises, and any emergency statutory or any other
statutory remedy. Tenant shall not interpose any counterclaim or counterclaims
or claims for set-off, recoupment or deduction of Minimum Annual Rent or
Additional Rent in a summary proceeding for nonpayment of Minimum Annual Rent or
Additional Rent or other action or summary proceeding based on termination,
holdover or other default in which Landlord seeks repossession of the Leased
Premises from Tenant.

38. Lease Recording. It is understood and agreed that Landlord shall not record
the within Lease Agreement among the Land Records of Baltimore County, Maryland,
for any purpose.

39. Notice of Default to Landlord and Mortgagee and Right to Cure. Tenant shall
give, by registered mail, a written notice of any failure by Landlord to perform
any of its obligations under this Lease to Landlord which shall specifically set
forth the nature of the nonperformance by the Landlord and shall give the
Landlord thirty (30) days within which to cure such default or non-performance.
However, if such default or non-performance reasonably requires more than thirty
(30) days to cure, Landlord shall not be in default if such cure is commenced
within such thirty (30) day period and thereafter diligently pursued to
completion. Said notice of default shall be a condition precedent to the
institution by Tenant of any judicial proceedings for nonperformance or default
against the Landlord. Tenant agrees to give any mortgagee and/or Trust Deed
Holders whose name and address have been furnished to Tenant in writing, by
registered mail, a copy of any notice of default served upon the Landlord.
Tenant further agrees that if Landlord shall fail to cure such default within
the time provided for in this Lease Agreement, then the mortgagees and/or Trust
Deed Holders shall have an additional thirty (30) days within which to cure such
default or, if such default cannot be cured within that

                                       28


<PAGE>




time, then such additional time as may be necessary if within such thirty (30)
days, any mortgagee and/or Trust Deed Holders has commenced and is diligently
pursuing the remedies necessary to cure such default, in which event this Lease
shall not be terminated while such remedies are being so diligently pursued.

40.   Miscellaneous Provisions.

construal, validity, performance and enforcement of this Lease.

required under the terms of this Lease, Landlord may grant or deny such consent
or approval in its sole discretion unless otherwise specified herein.

      (h) Separability. If any term or provision of this Lease or applications
thereof to any person or circumstance shall, to any extent, be invalid or
unenforceable, the remaining terms and provisions of this Lease, or the
application of such term or provision to persons or circumstances other than

and each term and provision of this Lease shall be valid and enforced to the
fullest extent permitted by law.

      (i) Counterparts. This Lease has been executed in several counterparts,
but all counterparts shall constitute one and the same legal document.

the corporation has

                                       29


<PAGE>




full right and authority to enter into this Lease, and that each and both of the
persons signing on behalf of the corporation were authorized to do so. If Tenant
signs as a partnership, each of the persons executing this Lease on behalf of
Tenant does hereby covenant and warrant that Tenant is a duly formed and validly

into this Lease, and that each of the persons signing on behalf of the
partnership were authorized to do so.

      (k) Examination of Lease. Submission of this Lease for examination or

delivery by both Landlord and Tenant.

      (l) Interpretation. Although the printed provisions of this Lease were
drawn by Landlord, this Lease shall not be construed for or against Landlord or
Tenant, but this Lease shall be interpreted in accordance with the general tenor
of the language in an effort to reach the intended result.

      (m) Entire Agreement; Modification. This Lease contains the entire
agreement between the parties, and any agreement hereafter made shall be
ineffective to change, discharge or effect an abandonment in whole or in part
unless such agreement is in writing and signed by the party against whom
enforcement of the change, modification, discharge or abandonment is sought.
Acceptance of, or acquiescence in, a course of performance rendered under this
or any prior agreement between the parties or their affiliates shall not be
relevant or admissible to determine the meaning of any term of this Lease.

      (n) Termination. This Lease and the tenancy hereby created shall cease and
determine at the end of the Lease Term, or any extension or renewal thereof,
without the necessity of any notice from either Landlord or Tenant to terminate
the same, and Tenant hereby waives notice to vacate the Leased Premises and
agrees that Landlord shall be entitled to the benefit of all provisions of law
respecting the summary recovery of possession of premises from a tenant holding
over to the same extent as if statutory notice had been given. For the period of
three (3) months prior to the expiration of the Lease Term or of any extension
or renewal thereof, Landlord shall have the right to show the Leased Premises
and all parts thereof to prospective tenants between the hours and 9:00 am and
5:00 pm, on any day except Saturday and Sunday and except any legal holiday on
which Tenant shall not be open for business.

      (o) Corporate Approval. If Tenant is a corporation, Tenant covenants and
warrants that it has the requisite corporate approval to enter into and execute
this Lease Agreement and accordingly, shall provide to Landlord, as soon as
practicable following execution of this Lease, a copy of an executed resolution
by its Board of Directors, authorizing the execution of the Lease Agreement and
authorizing the individual executing this Lease to execute said Agreement on
behalf of and in the name of the Corporation. If Tenant shall fail to provide
the executed resolution within the time period required under this Section,
Landlord may, at its option, declare this Lease to be null and void and of no
further force or effect. If Tenant is a corporation it acknowledges that this
Lease is executed under seal and that a twelve year period of limitation
applies.

      (p)     Approval of Mortgage.  This Lease is contingent upon the approval
of any

                                       30


<PAGE>




and all mortgagees or other lenders of the Landlord. Landlord shall have thirty
(30) days from the execution of this Lease to obtain all necessary approvals
from this mortgagee or other lenders; and thereafter shall have the right to
extend said approval period an additional ten (10) days upon written notice to
Tenant. If said approvals cannot be obtained within the aforesaid period, this
Lease and the rights and duties of the parties hereunder, shall be null and void
and be of no further effect.

      (q) Zoning and Licensing Approvals. Anything herein elsewhere contained to
the contrary, this Lease and all the terms, covenants, and conditions hereof are
in all respect subject and subordinate to all zoning restrictions affecting the
Leased Premises, and the Building in which they are located, and the Tenant
agrees to be bound by such restrictions. The Landlord further does not warrant
that any license or licenses, permit or permits, which may be required for the
business to be conducted by the Tenant on the Leased Premises will be granted,
or, if granted, will be continued in effect or renewed, and any failure to
obtain such licence or licences, permit or permits, or any revocation thereof or
failure to renew the same, shall not release the Tenant from its obligations
under this Lease Agreement.

41. Quiet Enjoyment. If and so long as Tenant pays rent and additional rent
reserved by this Lease, and performs and observes all the covenants and
provisions hereof, Tenant shall quietly enjoy the Leased Premises, subject,
however, to the terms and provisions hereof.

42. Remedies Cumulative. No mention in this Lease of any specific right or
remedy shall preclude Landlord from exercising any other right or from having
any other remedy, or from maintaining any action to which it may otherwise be
entitled, either at law or equity; and the failure of Landlord to insist in any
one or more instances upon a strict performance of any covenant of this Lease or
to exercise any option or right herein contained shall not be construed as a
waiver of relinquishment for the future of such covenant, right or option, but
the same shall remain in full force and effect unless the contrary is expressed
in writing by Landlord.

43. Binding Effect. This Agreement and the covenants and conditions herein
contained shall be binding upon and shall inure to the benefit of Landlord, its
heirs, personal representatives, successors and assigns, and shall be binding
upon Tenant, its heirs, personal representatives, successors and assigns, and
shall inure to the benefit of Tenant and only such assigns of Tenant to whom the
assignment by Tenant has been consented to by Landlord.

      IN WITNESS WHEREOF, the parties hereto have duly executed this Agreement
the day and year first above written.

      (b) References and Conflicts. References appearing in Section 1(a) are
intended to designate some of the other places in the Lease where additional
provisions are applicable to the particular fundamental Lease provisions appear.
These references are for convenience only and shall not be deemed all inclusive.
Each reference in the Lease to any of the fundamental Lease provisions contained
in Section 1(a) shall be construed to incorporate all of the terms provided for
under such provisions, and such provisions shall be read in conjunction with all
other provisions of the Lease applicable thereto. If there is any conflict
between any of the fundamental Lease provisions set forth in Section 1(a) and
any other provisions of the Lease, the latter shall control.

      (c) Exhibits. The following drawings and special provisions are attached
hereto as exhibits and hereby made a part of this Lease:

             Exhibit A. Floor Plan of Leased Premises
             Exhibit B. Rules and Regulations

      (d) Addendums. The following special provisions are attached hereto as
addendums and hereby made a part of this Lease.

             Addendum 1 - Leased Premises.

2.    Premises.

      (a) Leased Premises. Landlord hereby leases to Tenant, and Tenant hereby
rents from Landlord, the Leased Premises as specified in Section 1(a)(1) located
in the building specified in Section 1(a)(2) (the "Building"). The leased
premises shall consist of approximately the square footage of rentable floor
space as specified in Section 1(a)(3), which included an agreed common area
factor of twelve percent (12%), and as outlined in red on the floor plan
attached hereto as Exhibit A. For the purposes of determining the square footage
of the Leased Premises, leasehold space is calculated by measuring from the
outside of any exterior walls of the Leased Premises to the center line of any
partitions constructed which separate the Leased Premises from the remaining or
adjacent premises of the Building.

      (b) The Building. Landlord and Tenant acknowledge that the gross leasable
area in the Building is specified in Section 1(a)(4) ("Gross Leasable Area" or

                                        2


<PAGE>




"GLA"). The GLA shall be used hereinafter for purposes of computing Tenant's
proportionate share of certain expenses payable to Landlord as Additional Rent.
Landlord reserves the right to modify the GLA of the Building from time to time
during the Lease Term as a result of construction of new improvements or the
demolition of existing improvements.

      (c) Tenant's Proportionate Share. Tenant's proportionate share of certain
expenses hereinafter made payable to Landlord as additional rent is specified in
Section 1(a)(5). Said computation is based upon the ratio of the total rentable
area in the Leased Premises to the GLA of the Building. The Proportionate Share
shall be modified during the Lease Term in the event that the GLA of the
Building is modified as described in Section 2(b) above.

3.    Term.

      (a) Lease Term. The term of the Lease (sometimes herein called the "Lease
Term") shall commence on the "Rent Commencement Date," January 1, 1997, and
shall continue for a period of nine (9) years from the first day of the calendar
month next following the first day of the Term, unless sooner terminated as
herein provided.

      (b) Acceptance of Leased Premises. Landlord shall deliver, and Tenant
agrees to accept, possession of the Leased Premises in an "as is" condition,
subject, however, to Landlord's performance of its agreed obligation to replace
at no charge to Tenant the carpet in the rear portion of the fourth floor. By
entering into possession, Tenant shall be deemed to have accepted the Leased
Premises, to have acknowledged that the same are in the condition called for
hereunder and to have agreed that the obligations of the Landlord imposed for
the delivery of the Premisses have been fully performed. It is expressly
understood and agreed that Landlord has made no representations or warranties
with respect to the Leased Premises.

4.    Rent.

      (a) Minimum Annual Rent. The minimum Annual Rent reserved hereunder shall
be as specified in Section 1(a)(8) which shall be payable by Tenant to the
Landlord during each Lease Year of the Lease Term in twelve (12) equal monthly
installments of Basic Monthly Rent each as specified in Section (a)(9), due in
advance, without notice or demand, and without set-off, deduction or abatement
of any kind, on the first day of every calendar month thereafter during the
Term. Rent shall be paid to Landlord (or its agent) as specified in Section
1(a)(18), or to such other persons or at such other address as Landlord may
designate from time to time.

      (b) Annual Adjustments to Minimum Annual Rent. On the first day of the
second Lease Year, and on the first day of each Lease Year thereafter during the
Lease Term, the Minimum Annual Rent (than in effect) shall be increased by 3
percent (3%).

      (c)    Additional Rent.

             (i) General. Whenever it is provided by the terms of this Lease
that Tenant is required to make any payment to Landlord other than of Minimum
Annual Rent, such payment shall be deemed to be additional rent ("Additional
Rent"). Unless otherwise expressly specified herein, Additional Rent shall be
paid by Tenant with the installment of Base Monthly Rent thereafter falling due.

Additional Rent shall include, but not be limited to:

                                        3


<PAGE>




             (ii) Basic Operating Expenses. Tenant shall pay to Landlord, as
Additional Rent, its Proportionate Share as set forth in Section 1(a)(5) of any
increase in the Basic Operating Expenses incurred by Landlord in the operation
of the Building during any calendar year over the Base Operating Expense Amount
specified in Section 1(a)(13). As used herein, the "Basic Operating Expenses"
shall mean the sum of all costs of operating, policing, managing, maintaining
replacing and repairing the (A) the Building, (B) the personal property used in
conjunction therewith, and (C) the land upon which the Building is situated and
all curbs and sidewalks adjacent to same. Such costs shall include the
following: the charges (including surcharges) for electricity, gas, fuel, steam,
water and sewer and any other utilities supplied to the Building; the cost of
public liability insurance, casualty insurance, rent loss insurance, umbrella
liability insurance, owned and non-owned automobile insurance and all other
insurance coverage carried by Landlord in connection with the Building; legal,
accounting, engineering and other professional fees; management fees (equal to
fifteen percent (15%) of the total Basic Operating Expenses, excluding real
estate taxes and utilities) and personnel costs, including, but not limited to,
reasonable salaries, wages, taxes, fringe benefits and other direct and indirect
costs paid to or on behalf of persons employed in the operation, supervision,
maintenance, management and repair of the Building and Building Area or engaged
to provide any maintenance, operating, repair or upkeep service to the Building
or Building Area, and any other Building personnel; costs of inspecting, and
depreciation of machinery and equipment; costs to maintain and operate a
Building office; security guards or security services deemed necessary by
Landlord; the cost of all service and maintenance contracts; landscaping
maintenance, including reasonable upgrades and replacements; parking facility
maintenance, including repairs, restriping, resurfacing, rebuilding, as well as
removal of snow, ice and debris and depreciation of all machinery and equipment
used therein or thereon; traffic control; sanitary and drainage control; public
address system; holiday decorations; disposal of trash; maintenance, repair and
replacement of mechanical and electrical equipment including heating,
ventilation and air conditioning equipment; window cleaning, janitorial service
and pest control service; maintenance and repair of elevators, stairways, rest
rooms, lobbies, hallways and other common areas and facilities; repainting and
redecoration of all common areas and facilities; sales or use taxes on supplies
or services; and all other reasonable maintenance and repair expenses and
supplies which are deducted by Landlord in computing its Federal income tax
liability; the cost of any capital improvements or alterations made by Landlord
to the Building after the Rent commencement Date of the Lease Term, that reduce
total operating charges, or which are required under any governmental law or
regulation that was not applicable to the Building at the time it was
constructed, such cost to be amortized over such reasonable period as Landlord
shall determine, together with interest on the unamortized balance at the rate
actually paid by Landlord on funds borrowed for purposes of constructing said
capital improvements or alterations; the cost of tools and equipment, materials
and uniforms, supplies and sundries reasonably necessary for the operation and
maintenance of the Building; the Building's share of all costs to maintain,
repair and/or replace as necessary any common driveways, facilities and
structures pursuant to easements, covenants or similar agreements affecting the
Building; charges of any kind imposed by any governmental authority in
connection with the use or occupancy of the Building, including any and all
license, permit, and inspection fees; "Real Estate Taxes" (as hereinafter
defined); and any other reasonable costs and expenses incurred by Landlord in
owning, maintaining, repairing or operating the Building or Building Area. The
Basic Operating Expenses shall not include: leasing commissions payable by
Landlord; the cost of capital improvements, as determined under sound accounting
principals,

                                        4


<PAGE>




except to the extent set forth above; or the costs of special services or
utilities separately charged to individual tenants of the Building.

             The term "Real Estate Taxes" shall mean all taxes and assessments,
general and special, ordinary and extraordinary, foreseen and unforeseen, now or
hereafter assessed, levied or imposed upon the Building, and the land on which
it is built, whether or not now customary, including, without limitation, all
other government al impositions and levies, front foot benefit charges and
adequate public facility costs and assessments, together with (i) any tax,
assessment, or other imposition in the nature of a real estate tax, (ii) any ad
valorem tax on rent or any tax on income if imposed in lieu of or in addition to
real estate taxes and assessments, and (iii) any taxes and assessments which may
hereafter be substituted for real estate taxes, including by way of illustration
only, any tax, capital levy, assessment, imposition or otherwise (whether a
business rental or other tax) now or hereafter levied upon Landlord on the rents
or income received from the Building or for Tenant's use or occupancy of or
conduct of business at the Leased Premises, or Tenant's improvements to or
furniture, fixtures or equipment in the Leased Premises. "Real Estate Taxes"
shall further mean any advances or escrow deposits paid or made to any taxing
authority or third party such as a lender on account of any of the foregoing.
"Real Estate Taxes" shall also include all costs, including reasonable attorney
fees, incurred by Landlord in contesting the validity or amount, or in attempts
to restrict increases in, any such taxes. The Real Estate Taxes for any calendar
year shall mean the Real Estate Taxes actually paid or due to be paid during
such calendar year, whether such Real Estate Taxes relates to such calendar year
or a fiscal year.

             (iii) Increases in Basic Operating Expenses. For each calendar year
during which any part of the Term falls, Tenant shall pay to Landlord Tenant's
Proportionate Share of the excess, if any, in Basic Operating Expenses for the
Leased Premises for such year (the "Excess Operating Expenses") over the Base
Operating Expense Amount. Such payment shall be prorated for any partial
calendar year during the Term.

             (iv) Electrical Service. Tenant shall reimburse Landlord on a
monthly basis for all electrical service to the Leased Premises (other than the
electrical service necessary for Landlord to provide standard heating and air
conditioning, which shall be included in "Basic Operating Expenses".) Landlord
shall pay the monthly bills for such services and submit copies of those bills
to Tenant for reimbursement, with no markup or management fee, and Tenant agrees
to pay each bill promptly in accordance with its terms.

             (v) Landlord's Enforcement Costs. Additional Rent shall include any
and all expenses incurred by Landlord, including reasonable attorneys' fees, for
the collection of monies due from Tenant and the enforcement of Tenant's
obligations under the provisions of this Lease. When Landlord, at Tenant's
expense, performs an obligation of Tenant pursuant to the terms of this Lease,
the actual out-of-pocket costs and expenses incurred by Landlord in performance
of such obligations shall be Additional Rent.

       (d)    Additional Rent Estimates and Adjustments.

              (i) On or before April 30 (or as soon thereafter as practicable)
of each calendar year, Landlord will submit to Tenant a comparative statement of
the actual increases incurred in Basic Operating Expenses for the preceding
calendar year over the Base Operating Expense Amount, setting forth in
reasonable detail: (i) a schedule of Basic Operating Expenses for the preceding

                                        5


<PAGE>




calendar year, and the amount of the Excess Operating Expenses for such
preceding year; (ii) the amount, if any, paid by Tenant to Landlord during the
preceding calendar year on account of the Excess Operating Expenses for such
preceding year; and (iii) the amount due from Tenant on account of the Excess
Operating Expenses for such preceding year, or the amount due from Landlord to
Tenant because of overpayment by Tenant on account of Excess Operating Expenses.
Landlord's comparative statement of Operating Expenses shall also include
Landlord's good faith estimate of Excess Operating Expenses for the then-current
calendar year and an estimated "Monthly Portion of Excess Operating Expenses"
equal to one-twelfth (1/12) of said good faith estimate of Excess Operating
Expenses.

              (ii) Tenant shall pay Landlord, within thirty (30) days of
Tenant's receipt of such statement, as Additional Rent, any amounts due from
Tenant on account of Excess Operating Expenses for the preceding year. Tenant
shall also make payments to Landlord, on account of the Excess Operating
Expenses for the then current calendar year, as follows:

                     (A) On the first day of the first full month following
receipt

by Tenant of the Landlord's comparative statement of Basic Operating Expenses,
Tenant shall pay to Landlord an amount equal to the Monthly Portion of Excess
Operating Expenses multiplied by the number of months elapsed in the current
calendar year (including the month in which the payment is made); and

                     (B) Commencing on the first day of the second full month
following

receipt by Tenant of Landlord's comparative statement of Basic Operating
Expenses, and continuing until the receipt by Tenant of the next annual
comparative statement, the minimum monthly installments of rent due hereunder
shall be increased by an amount equal to the Monthly Portion of Excess Operating
Expenses.

              (iii) Landlord shall refund any overpayment made by Tenant within
thirty (30) days after Landlord's submission to Tenant of the aforesaid
operating charge statement for such calendar year.

              (iv) Contemporaneously with presentation of Landlord's statement
showing actual figures for the year, Landlord shall furnish to Tenant, in
writing, a detailed statement of Basic Operating Expenses and copies of Real
Estate Tax bills. If it shall be determined that there is an error in Landlord's
statement, Tenant shall be entitled to a credit for any overpayment, or, if
Landlord billed Tenant less than should have been billed to Tenant, Tenant shall
pay such difference to Landlord. Any payment, refund or credit made pursuant to
Section 4(c) or 4(d) shall be made without prejudice to any right of Tenant to
dispute, or of Landlord to correct, any item(s) as billed pursuant to the
provision hereof; provided, however, such right to correct or adjust rental
payments shall terminate at the expiration of two (2) years after the date any
payment shall have become due.

              (v) Tenant's obligation to pay any Additional Rent accruing during
the Lease Term pursuant to this Section shall apply pro rata to the
proportionate part of the calendar year as to Basic Operating Expenses, in which
this Lease begins or ends, for the portion of each such year during which this
Lease is in effect. Such obligation to make payments of such Additional Rent
shall survive the expiration or sooner termination of the Lease Term, whether or
not this Lease is superseded by a subsequent lease of the Leased Premises or of
any other space or Tenant leaves the Building; any such superseding lease shall
not serve to supersede Tenant's obligation for any such additional rent unless
it makes

                                        6


<PAGE>




express reference thereto and recites that such additional rent is abated in
consideration of the superseding lease.

              (vi) If, during the Term of this Lease, there shall be a reduction
or elimination of any particular component of Basic Operating Expenses by reason
of the introduction of a labor-saving device, energy conservation device,
capital improvement or replacement installed by Landlord, the corresponding item
of expense in the Base Operating Expense shall be eliminated or reduced in the
same proportion as the reduction of that item in the Basic Operating Expense for
the purposes of calculating Tenant's share of Excess Operating Expenses.

              (vii) In the event that Landlord shall make a capital expenditure
for an Essential Capital Improvement (as hereinafter defined) during the Term of
this Lease, the annual amortization of such expenditure (determined by dividing
the amount of the expenditure by the useful life of the improvement) plus
interest on the unamortized balance at the rate actually paid by Landlord for
funds borrowed by Landlord to construct or otherwise provide such Essential
Capital Improvement, shall be deemed an Operating Expense for each year of such
useful life. As used herein, an "Essential Capital Improvement" means any of the
following: (A) a labor saving device or other installation, improvement or
replacement which reduces Operating expenses; (B) an installation or improvement
required by reason of any law, ordinance or regulation of any governmental or
quasi-governmental body, which requirement did not exist (or was not applicable
to the Building) on the date of execution of this Lease; or (C) an installation
or improvement which directly enhances the safety of tenants in the Building
generally (as, for example, but without limitation, for fire safety or
security); provided, however, any expense treated as an Essential Capital
Improvement hereunder must, at Tenant's option and expense, be certified by
independent auditors for Landlord as constituting an Essential Capital
Improvement under generally accepted accounting principles.

      (e) Payment of Rent. In the event Minimum Annual Rent or Additional Rent
is not paid within ten (10) days after the same is due, a late charge equal to
five percent (5%) of the delinquent amount shall be assessed as liquidated
damages for the additional administrative charges incurred by Landlord as a
result of such late payment. Tenant also agrees to pay all reasonable attorney
fees incurred by Landlord as a result of Tenant's delinquent payment of rent. No
payment by Tenant or receipt by Landlord of lesser amounts of rent than those
herein stipulated shall be deemed to be other than on account of the earliest
unpaid stipulated rent. No endorsement or statement on any check or any letter
accompanying any check or payment as rent shall be deemed an accord and
satisfaction, and Landlord may accept such check or payment without prejudice to
Landlord's right to recover the balance of such rent or pursue any other remedy
provided in this Lease. If Landlord shall pay any monies, or incur any expenses
in correction of violation of covenants herein set forth, the amount so paid or
incurred shall, at Landlord's option, and on written notice to Tenant, be
considered Additional Rent payable by Tenant with the first installment of
rental thereafter becoming due and payable. If Landlord receives from Tenant two
(2) or more returned or "bounced" checks in any twelve (12) month period,
Landlord may require all future rent be paid by cashier's or certified check.

5. Security Deposit. Tenant has deposited with Landlord the sum specified in
Section 1(a)(12). Said deposit shall constitute advance rental and shall be held
by Landlord as security for the faithful performance by Tenant of all the terms,
covenants and conditions of this Lease to be kept and performed by Tenant during
the Lease Term. If, at any time during the Lease Term, any payment of Minimum
Annual Rent or Additional Rent herein reserved shall be overdue and unpaid, the

                                        7


<PAGE>




Landlord may, at its option, appropriate and apply any portion of said security
deposit to the payment of any such overdue rent or other sum. Landlord shall
have the unrestricted right (but not the obligation) to apply any part of the
Security Deposit to cure any Default (as described in Section 20 hereof).

      In the event of the failure of Tenant to keep and perform any other items,
covenants and conditions of the Lease to be kept and performed by Tenant, then
Landlord, at its option, may appropriate and apply the entire security deposit,
or so much thereof as may be necessary, to compensate Landlord for loss or
damage sustained or suffered by Landlord due to such breach by Tenant. Should
the entire security deposit, or any portion thereof, be appropriated and applied
by Landlord for the payment of overdue rent, to cure any default, or other sums
due and payable to Landlord by Tenant hereunder, then Tenant shall remit to
Landlord, within ten (10) days of the written demand of Landlord, a sufficient
amount in cash to restore the security deposit to the original sum. Tenant's
failure to do so shall constitute a breach of the Lease. Should Tenant comply
with all of said terms, covenants and conditions of the Lease and promptly pay
all Minimum Annual Rent and Additional Rent herein provided as it falls due,
then the security deposit shall be returned in full, without interest, to Tenant
within thirty (30) days of the Expiration Date or earlier termination of the
Term of this Lease. Tenant shall have no right to direct the application of any
part of the Security Deposit.

      Landlord may deliver the funds deposited hereunder by Tenant to the
purchaser of Landlord's interest in the building and/or the Leased Premises in
the event that such interest is sold, and thereupon Landlord shall be discharged
from any further liability with respect to such security deposit.

6. Improvement of the Leased Premises. Intentionally deleted.

7. Alterations or Improvements by Tenant. Except for the incidental hanging of
pictures, installation of shelves, and other painting and decoration of the
Leased Premises which do not affect the structure of the Leased Premises, Tenant
shall not make any alterations, additions, or improvements, structural or
otherwise (collectively, "Alterations") in the Leased Premises (such as
carpeting, telephone installation, decoration and installation of specialized
equipment), without the prior written consent of Landlord, which consent shall
not be unreasonably withheld. Tenant shall not install any equipment of any
nature whatsoever which may affect the insurance rating of the Building, or
which may necessitate any changes, replacements or additions to the water
system, plumbing system, heating system, air-conditioning system, telephone
system or the electrical system of the Leased Premises, without the prior
written consent of Landlord, which consent shall not be unreasonably withheld.
Tenant shall pay all costs to make such changes, replacements or additions.

      Tenant hereby agrees that all Alterations made in, to, or on the Leased
Premises shall, unless otherwise provided by written agreement, be the property
of Landlord and shall remain upon and be surrendered with the Leased Premises on
the Expiration Date or other termination of this Lease, unless Landlord shall,
prior to such expiration or termination have given Tenant not less than 15 days
prior written notice to remove the same, in which event Tenant shall at its
expense forthwith remove such Alterations. Any or all wiring and cabling, such
as telephone, computer and data wires installed by Tenant shall be removed by
Tenant at its sole cost, and the Leased Premises shall be restored to their
original condition by the Expiration Date, ordinary wear and tear excepted. All
property permitted or required to be removed by Tenant at the end of the term
remaining in the Leased Premises after Tenant's removal shall be deemed
abandoned and may, at

                                        8


<PAGE>




the election of Landlord, either be retained as Landlord's property or may be
removed from the premises by Landlord at Tenant's expense.

8.    Use of Leased Premises.

       (a) Use. Tenant shall use and occupy the Leased Premises for the singular
purpose specified in Section 1(a)(11) and for no other purpose. Tenant shall not
use or permit the Leased Premises to be used for any other purpose or purposes
without the prior written consent of Landlord, which consent may be granted or
withheld in its sole discretion.

      (b) Compliance. Tenant, at its expense, shall comply with the laws, rules
and regulations of any federal, state or municipal authority, or the Maryland
Fire Underwriters Rating Bureau, or with any notice from any public officer
pursuant to law, or with any notice from any insurance company pertaining to
Tenant's occupancy or use of the Leased Premises, whether such notice shall be
served on Landlord or Tenant. In furtherance of the foregoing, and provided
Tenant shall first have obtained Landlord's prior written consent (which Tenant
agrees to promptly request), Tenant shall, at Tenant's sole cost and expense,
make such changes, alterations, renovations or modifications to the Leased
Premises (except for structural repairs) which are necessitated or required by
any such Law.

              (i) Legal. Tenant shall not use or permit the Leased Premises or
any part thereof to be used in violation of any present or future applicable
law, regulation or ordinance, or of the certificate of occupancy issued for the
Building or the Leased Premises, and shall immediately discontinue any use of
the Leased Premises which is declared by any governmental authority having
jurisdiction to be in violation of law or said certificate of occupancy. Tenant
will not use or permit the Leased Premises to be used for any purposes that
interfere with the use and enjoyment of the Building by Landlord or the other
tenants, which will increase the existing rate of insurance on the Building or
which violate the requirements of any insurance company insuring the Building or
its contents, or which, in Landlord's sole discretion, impair the reputation of
the Building. Tenant shall refrain from and discontinue such use immediately
upon receipt of written notice from Landlord.

              (ii) Fire and Safety. Tenant shall not do, or permit anything to
be done in the Leased Premises, or bring, use or keep anything therein, which
will in any way increase the rate of fire insurance on the Building, or
invalidate or conflict with fire insurance policies on the Building, fixtures or
on property kept therein. Tenant agrees that any increases of fire insurance
premiums on the Building or contents caused by the occupancy of Tenant and any
expense or cost incurred in consequence of negligence or the willful action of
Tenant, Tenant's employees, agents, servants, invitee, or licensees shall be
deemed Additional Rent and paid as accrued.

      (c) Environmental Protection. Tenant and Tenant's employees and agents
shall not dispose of any oil, petroleum or chemical liquids or solids, liquid or
gaseous products or any hazardous waste or hazardous substance including,
without limitation, asbestos (hereinafter collectively referred to as "hazardous
waste"), as those terms are used in the Comprehensive Environmental Response,
Compensation and Liability Act of 1980, or in any other federal, state or local
law governing hazardous substances (hereinafter referred to as the "Act"), as
such laws may be amended from time to time at, upon, under or within the Leased
Premises or the Building or the land on which it is built, or into the plumbing
or sewer or water system servicing the Leased Premises or the Building, nor
shall Tenant, its

                                        9


<PAGE>




employees or agents cause or permit the discharge, spillage, uncontrolled loss,
seepage or filtration of any hazardous waste at, upon, under or within the
Leased Premises or the Building or the land or into the plumbing or sewer or
water system servicing the same. Tenant shall comply in all respects with the
requirements of the Act and related regulations, and shall notify Landlord
immediately in the event of its discovery of any hazardous waste at, upon, under
or within the Leased Premises or the Building or the land.

      (d) Indemnification. Tenant shall indemnify Landlord against all costs,
expenses, liabilities, losses, damages, injunctions, suits, fines, penalties,
claims, and demands, including reasonable attorneys' fees, arising out of any
violation of or default in the covenants of this Section 8. The provisions of
Sections 8(b) and (c) and this Section 8(d) shall survive the expiration of the
Lease Term.

      (e) Moving and Deliveries. No freight, furniture, heavy machinery, heavy
equipment, including computer equipment or other bulky matter or fixtures of any
description shall be transferred into or out of the Building or carried in the
elevators, without Landlord's prior written consent and approval. In obtaining
the Landlord's approval as required under this paragraph, Tenant agrees to
provide Landlord with all technical specifications concerning the equipment and
machinery and to pay the costs of any and all structural changes which in the
sole discretion of the Landlord are required to be made in order to safely and
efficiently accommodate such equipment or machinery. If such machinery or
equipment requires special handling, Tenant agrees to employ only persons
holding the proper licences to do said work, and that all work in connection
therewith shall comply with any applicable Federal, State, County or other
governing laws, rules or regulations. Tenant shall promptly remove from the
public areas within or adjacent to the Building any of Tenant's property
delivered or deposited there, and shall be liable for any damage to the Building
or the Leased Premises caused by its moving and deliveries.

      (f) Excessive Floor Load. Landlord shall have the right to prescribe the
weight and method of installation and position of safes or other heavy fixtures
or equipment. Tenant will not, without Landlord's prior written approval,
install in the Leased Premises any fixtures, equipment or machinery that will
place a load upon the floor exceeding the designed floor load capacity. Tenant
shall be liable for all damage done to the Building by installing or removing a
safe or any other article of Tenant's office equipment, or due to its being in
the Leased Premises. Landlord shall repair any such damage at Tenant's expense,
and Tenant shall pay the cost therefor to Landlord upon demand, as Additional
Rent.

9. Taxes on Tenant's Property. Tenant shall be liable for, and shall pay at
least ten (10) days before delinquency, all taxes levied against any personal
property or trade fixtures placed by Tenant in or about the Leased Premises. If
any such taxes on Tenant's personal property or trade fixtures are levied
against Landlord or Landlord's property, or if the assessed value of the Leased
Premises is increased by the inclusion therein of a value placed upon such
personal property or trade fixtures of Tenant, and if Landlord, after written
notice to Tenant, pays the taxes based upon such increased assessments (which
Landlord shall have the right to do regardless of the validity thereof, but
under protest if requested by Tenant), Tenant shall upon demand repay as
Additional Rent to Landlord a sum equal to the taxes levied against Landlord or
the portion of such taxes resulting from such increase in the assessment;
provided that, in any such event, Tenant shall have the right, at Tenant's sole
cost and expense, to bring suit to recover the amount of any such taxes so paid
under protest, and any amount so recovered shall belong to Tenant.

                                       10

10. Rules and Regulations. Tenant covenants on behalf of itself, its employees,
agents, licensees and invitees to comply with the rules and regulations set
forth in Exhibit B, which is attached hereto and made a part hereof (the "Rules
and Regulations"). Landlord shall have the right, in its sole discretion, to
make reasonable additions and amendments to the Rules and Regulations from time
to time and Tenant covenants that Tenant, its employees, agents, licensees and
invitees will comply with additions and amendments to the Rules and Regulations
upon Landlord's provision to Tenant of a written copy of the same. Any
unremedied default by Tenant, or any other party set forth above, of any of the
material provisions of the Rules and Regulations as set forth in Exhibit B, or
as amended from time to time, shall be considered to be a default under the
terms of this Lease. Nothing contained in this Lease shall be construed to
impose upon Landlord any duty or obligation to enforce the Rules and
Regulations, or any amendments or additions thereto, against any other tenant.
Landlord shall have no liability to Tenant or any other party for violations of
the Rules and Regulations by any party whatsoever. If there is any inconsistency
between this Lease and the Rules and Regulations, the Lease shall govern.

11.   Utilities and Services.

       (a) Building Standard Services and Utilities. As long as Tenant is not in
default under any of the covenants of this Lease, Landlord shall, if and insofar
as existing facilities permit, furnish sufficient electric current for routine
and normal requirements for lighting and typical office equipment and machinery,
such as typewriters, calculators, personal computers, small copiers and similar
items, subject to the limitations of Section 11(b). Landlord shall furnish hot
and cold water for lavatory and drinking purposes, lavatory supplies, and
Building standard fluorescent tube replacements and nightly cleaning and jani-
torial services Monday through Friday. Landlord further agrees to furnish
heating and cooling during the appropriate seasons of the year, during the
Standard Building Operating Hours and on the days set forth in Section l(a)(15),
exclusive of the Building Holidays specified in Section l(a)(16), with holidays
falling on Saturday observed both on said day and on the preceding Friday, and
holidays falling on Sunday observed on the following Monday.

      (b) Overtime Services. Landlord shall be under no obligation to furnish
electric power at any hours other than normal business hours, or for the
operation of any other electrical equipment or appliance, unless arrangements
for such after-hours operations, and for the installation of such electrical
equipment or appliance, shall have been made pursuant to terms and conditions
acceptable to Landlord and embodied in a separate written agreement between
Landlord and Tenant. In the event that Tenant uses electrical services in excess
of that required for normal office use or during periods other than normal
business hours or both, then such excess services shall be supplied at the
expense of the Tenant, pursuant to terms, conditions and costs established by
the Landlord in its sole discretion. Should Tenant require heating and cooling
services beyond the hours stipulated in Section 11(a), Landlord will furnish
such additional service at the then-prevailing hourly rate, as established by
Landlord from time to time, provided that Tenant gives Landlord no less than
twenty-four (24) hours advance written notice of the need therefor.

      (c) Interruption or Reduction of Service. In no event shall Landlord be
liable to Tenant for any interruption or failure in the supply of any utilities
to the Leased Premises and the Building. Landlord reserves the right to
interrupt service of the heat, plumbing, air conditioning, cooling, electric,
and sewer and water systems, when necessary, by reason of accident, or of
repairs, alterations or improvements which in the judgment of Landlord are
desirable or necessary to

                                       11


<PAGE>




be made, until such repairs, alterations or improvements shall have been
completed; and Landlord shall have no responsibility or liability for failure to
supply heat, plumbing, air conditioning, cooling, electric, and sewer and water
service, or other service or act for the benefit of Tenant, when prevented from
so doing by strikes, accidents or by any other causes beyond Landlord's
reasonable control, or by orders or regulations of any federal, state, county,
or municipal authority, or by any failure to receive suitable fuel supply, or
inability despite exercise of reasonable diligence to obtain the regularly-used
fuel or other suitable substitute; and Tenant agrees that Tenant shall have no
claim for damages nor shall there be any abatement of Base Annual Rent in the
event that any of said systems or service shall be discontinued or shall fail to
function for any reason. If any public utility supplying any utility to the
Building, or any law, order or regulation of any federal, state, county or
municipal authority requires that Landlord or Tenant must reduce or maintain a
certain level of consumption of electricity or any other utility or interior
temperature for the Leased Premises or the Building, which affects the normal
business hours or the provision of any utility the Leased Premises or the
Building, Landlord and Tenant shall each adhere to and abide by such requirement
without any reduction in rent or in any of Tenant's other obligations hereunder.
Landlord's obligation to supply heat and air conditioning are subject to
applicable laws and regulations as to energy conservation and other
restrictions.

       (d)    Excessive Electrical Usage.

              (i) Tenant will not install or operate in the Leased Premises any
heavy duty electrical equipment or machinery, without obtaining the prior
written consent of Landlord, which consent shall not be unreasonably withheld.
Landlord may require, as a condition of its consent to the installation of such
equipment or machinery, payment by Tenant, as Additional Rent, for such excess
consumption of electricity as may be occasioned by the operation of said
equipment or machinery. Landlord may make periodic inspections of the Leased
Premises at reasonable times to determine that Tenant's electrically operated
equipment and machinery complies with the provisions of this Section and Section
11(e).

              (ii) Landlord shall have the right to require that one or more
separate meters or submeters be installed to record the consumption or use of
electricity, or to cause a reputable independent electrical engineer to survey
and determine the quantity of electricity consumed by such excessive use. The
cost of any such survey or meters and of installation, maintenance and repair
thereof shall be paid by Tenant. Tenant agrees to pay Landlord (or the utility
company, if direct service is provided by the utility company), promptly upon
demand therefor, for all such electricity consumption as shown by said meters,
or a flat monthly charge determined by the survey, as applicable, at the rates
charged for such service by the local public utility company.

      (e) Excessive Heat Generation. Landlord shall not be liable for its
failure to maintain comfortable atmospheric conditions in all or any portion of
the Leased Premises, due to heat generated by any equipment or machinery
installed by Tenant (with or without Landlord's consent) that exceeds
generally-accepted engineering design practices for normal office purposes. If
Tenant desires additional cooling to offset excessive heat generated by such
equipment or machinery, Tenant shall pay for auxiliary cooling equipment and its
operating costs, including, without limitation, electricity, gas, oil and water,
or for excess electrical consumption by the existing cooling system, as
appropriate.

                                       12


<PAGE>




      (f) Security. Any security measures that Landlord may undertake are for
protection of the Building only and shall not be relied upon by Tenant to
protect Tenant, its property, its employees and/or their property.

12. Landlord's Right of Entry. Landlord, its agents, employees and contractors
shall have the right to enter the Leased Premises at all reasonable times,
including emergencies determined by Landlord, (a) to make inspections or to make
repairs, replacements and improvements to Leased Premises or other premises as
Landlord may deem necessary or reasonably desirable to the Premises or to any
other portion of the Building or which Landlord may elect to perform; (b) to
perform nightly cleaning of the Leased Premises; (c) to exhibit the Leased
Premises to prospective purchasers at any reasonable time, or to prospective
tenants during the last one hundred and eighty (180) days of the Lease Term; and
(d) for any purpose whatsoever relating to the safety, protection or
preservation of the Building. Such entry by Landlord shall be, whenever
reasonably possible, during normally business hours, except in cases of
emergency. Landlord shall use reasonable best efforts to minimize interference
to Tenant's business when making repairs, but, unless otherwise agreed with
Tenant, Landlord shall not be required to perform the repairs at any time other
than during normal working hours. The right and authority hereby reserved do not
impose, no does the Landlord assume by reason thereof, any responsibility or
liability whatsoever for the care, maintenance or supervision of the Leased
Premises or any pipes, fixtures, appliances or appurtenances therein contained
or therewith in any manner connected.

13.   Maintenance and Repairs.

       (a) Landlord Responsibilities. Landlord shall make structural repairs to
the Leased Premises necessary for safety and tenantability, and shall maintain
and repair all Building equipment serving the Leased Premises and all exterior
plate glass in the Leased Premises, and the cost of all such repairs or
maintenance shall be included in Basic Operating Expenses. Tenant waives the
right to make repairs at Landlord's expense under any law, statute or ordinance
now or hereafter in effect. Landlord reserves the right at any time and from
time to time, as often as Landlord deems desirable, without the same
constituting an actual or constructive eviction and without incurring any
liability to Tenant or otherwise affecting Tenant's obligations under this
Lease, to make changes, alterations, additions, improvements, repairs,
relocations or replacements in or to the Building and the fixtures and equipment
thereof. Landlord reserves the right from time to time to install, use,
maintain, repair and replace pipes, ducts, conduits, wires and appurtenant
meters and equipment for service to other parts of the Building, above the
ceiling surfaces, below the floor surfaces, within the walls and in the central
core areas, and to relocate any pipes, ducts, conduits wires and appurtenant
meters and equipment included in the Leased Premises which are located in the
Leased Premises or located elsewhere outside the Leased Premises. Landlord shall
use reasonable efforts not to disturb Tenant's business operations when making
repairs to the Leased Premises or the Building. Nothing contained herein shall
be deemed to relieve Tenant of any duty, obligation or liability with respect to
making any repair, replacement or improvement or complying with any law, order
or requirement of any government or other authority and nothing contained herein
shall be deemed or construed to impose upon Landlord any obligation,
responsibility or liability whatsoever, for the care, supervision or repair of
the Building, or any part thereof, other than as expressly provided in this
Lease.

      (b) Tenant Responsibilities. Tenant will keep the Leased Premises and the
fixtures and equipment therein in good order and condition, will take good care

                                       13


<PAGE>




thereof and will suffer no waste or damage thereto. Tenant will promptly repair
at its own expense any damage to the Leased Premises caused by bringing into the
premises any property for Tenant's use or by the installation or removal of such
property, regardless of fault or by who such damage shall be caused, unless
caused by Landlord, its agents, employees or contractors; and, in default of
such repairs by Tenant, Landlord shall make the same and Tenant agrees to pay
the costs thereof to Landlord promptly upon Landlord's demand therefor. At the
expiration or other termination of the Lease Term, Tenant will surrender the
Leased Premises broom clean and in the same order and condition in which they
were on the Rent Commencement Date, ordinary wear and tear excepted. All repairs
and maintenance required to be performed by Tenant shall be made or performed
immediately upon the occurrence of the necessity therefor, and shall be made or
performed in a first class manner, using first class materials, by a contractor
approved by Landlord and bonded unless waived by Landlord, and shall be made or
performed in accordance with (i) all laws and all applicable governmental codes
and requirements, and (ii) insurance requirements. Maintenance and repair of
equipment such as kitchen fixtures, auxiliary air-conditioning equipment,
private bathroom fixtures and any other type of special equipment, together with
related plumbing or electrical services, whether installed by Tenant or by
Landlord on behalf of Tenant, shall be the sole responsibility of Tenant, and
Landlord shall have no obligation in connection therewith. If Tenant refuses or
neglects to promptly commence and complete repairs or maintenance necessary to
satisfy the provisions of this Section, the Landlord may, but shall not be
required to, make and complete said repairs or maintenance and Tenant shall pay
the cost therefor (including overhead) to Landlord upon demand, as Additional
Rent.

14.   Common Areas.

       (a) Common Areas Defined. In this Lease, "common areas" means all areas,
facilities and improvements provided, from time to time, in the Building for the
mutual convenience and use of tenants or other occupants of the Building, their
respective agents, employees, and invitees and shall include, if provided, but
shall not be limited to, the lobbies and hallways, the public restrooms, the
parking areas and facilities, access roads, driveways, retaining walls,
sidewalks, walkways, landscaped areas, and exterior lighting facilities.

      (b) Landlord's Control. Landlord shall, as between Landlord and Tenant, at
all times during the term of the Lease have the sole and exclusive control,
management and direction of the common areas, and may at any time and from time
to time during the term exclude and restrain any person from use or occupancy
thereof, excepting, however, Tenant and other tenants of Landlord and bona fide
invitee of either who make use of said areas in accordance with the rules and
regulations established by Landlord from time to time with respect thereto. The
rights of Tenant in and to the common areas shall at all times be subject to the
rights of others to use the same in common with Tenant, and it shall be the duty
of Tenant to keep all of said areas free and clear of any obstructions created
or permitted by Tenant or resulting from Tenant's operation. Landlord may at any
time and from time to time close all or any portion of the common areas to make
repairs or changes or to such extent as may, in the opinion of Landlord, be
necessary to prevent a dedication thereof or the accrual of any rights to any
person or to the public therein, to close temporarily any or all portions of the
said areas to discourage noncustomer parking, and to do and perform such other
acts in and to said areas as, in the exercise of good business judgment,
Landlord shall determine to be advisable with a view to the improvement of the
convenience and use thereof by tenants, their employees, agents, and invites.

                                       14


<PAGE>




      (c) Changes and Additions to the Building, Additional Construction.
Landlord hereby reserves the right at any time to make alterations or additions
to the Building, as well as in or to the street entrances, halls, passages,
stairways and other common facilities thereof. Tenant agrees that Landlord shall
at all times have the right and privilege of determining the nature and extent
of the common areas, and of making such changes, rearrangements, additions or
reductions therein and thereto from time to time which in its opinion are deemed
to be desirable and for the best interest of all persons using the common areas
or which are as a result of any federal, state or local environmental protection
or other law, rule, regulation, guideline or order. The purpose of the floor
plan attached hereto as Exhibit A is to show the approximate locational
relationship of the Leased Premises to other units in the Building and the
common areas as of the Rent Commencement Date. Nothing described in Exhibit A
shall limit or prevent Landlord from effecting any change or alteration to the
Building or the land upon which it is built as described in this paragraph.

      (d) Parking. Tenant shall have the right to utilize the Building's parking
facilities on a nonexclusive basis with other tenants of the Building, upon such
reasonable terms and conditions as may from time to time be established by
Landlord. Landlord reserves the right in its absolute discretion to determine
whether the parking facilities are becoming crowded and to allocate and assign
parking spaces among Tenant and the other tenants. Tenant shall not use parking
areas for the overnight storage of vehicles, other than Tenant-owned corporate
vehicles which Landlord and Tenant have previously agreed will be regularly
parked overnight at the Building. It is understood and agreed that Landlord
assumes no responsibility, and shall not be held liable, for any damage or loss
to any automobiles parked in the parking facilities or to any personal property
located therein, or for any injury sustained by any person in or about the
parking facilities.

15.   Surrender and Inspection.

      (a) Surrender. Upon the Expiration Date or other termination of the term
of this Lease, Tenant shall quit and surrender the Leased Premises to the
Landlord in as good order and condition as when received, ordinary wear and tear
excepted, and Tenant shall remove all of its property from the Leased Premises
by the Expiration Date or other termination of this Lease, all to the reasonable
satisfaction of the Landlord. Tenant's obligation to observe or perform this
covenant shall survive the expiration or other termination of this Lease.

      (b) Inspection. Tenant shall have the right to be present at time of final
inspection of the Leased Premises to determine if any damages were done thereto,
if Tenant notifies Landlord by certified mail of its intention to move, date of
moving and new address. The notice of Tenant's desire to be present at the final
inspection of the Leased Premises shall be given at least fifteen (15) days
prior to the date of moving. Upon receipt of such notice, Landlord shall notify
Tenant of time and date when the Leased Premises are to be inspected. The
inspection shall occur within five (5) days before or five (5) days after
Tenant's date of moving, said inspection date to be designated by Landlord.
Tenant shall be deemed to have been advised of its rights under this paragraph
by execution of this Lease.

      (c) Fixtures and Personal Property Remaining. If Tenant does not remove
Tenant's furniture, equipment, machinery, trade fixtures, floor coverings and
all other items of personal property of every kind and description from the
Leased Premises prior to the Expiration Date, then Tenant shall be conclusively
presumed

                                       15


<PAGE>




to have conveyed the same to Landlord under this Lease as a bill of sale without
further payment or credit by Landlord to Tenant.

16. Tenant Holding Over. If Tenant holds possession of the Leased Premises after
the Expiration Date or other termination of this Lease, Landlord shall have the
option, exercisable in writing within thirty (30) days after the date of
termination of aforesaid, to treat Tenant as a trespasser, or as a tenant by the
month. If the Landlord fails to make such election then the Tenant shall be
deemed a tenant by the month, commencing with the first day after the
termination of the Lease at one hundred and fifty percent (150%) the Basic
Monthly Rent paid during the last month of the Term, and upon all the other
terms of this Lease, including the provisions of this paragraph. Said holdover
term shall terminate upon thirty (30) days notice from one party to the other.
Nothing contained herein shall be construed within said thirty (30) days after
the date of Lease termination as aforesaid as a consent by Landlord to the
occupancy or possession of the Leased Premises by Tenant after the termination
of the Lease, and Landlord, upon said termination, if Landlord elects to treat
Tenant as a trespasser, shall be entitled to the benefit of all public general
or public laws relating to the speedy recovery of the possession of land and
tenements held over by Tenant, whether now or hereafter in force and effect. If
Tenant fails to surrender the Leased Premises upon the expiration or other
termination of this Lease despite demand to do so by Landlord, Tenant shall
indemnify and hold Landlord harmless from all injury, loss, claims, expenses and
liability, including without limitation, any claim made by any succeeding tenant
and any attorneys' fees, founded on or resulting from such failure to surrender.

17. Covenant Against Assignment and Subletting. Tenant shall not assign,
mortgage or encumber this Lease, or any right hereunder, nor sublet the Leased
Premises or any part thereof, nor permit the Leased Premises to be used by
others without the prior written consent of Landlord, which consent shall not be
unreasonably withheld. Notwithstanding the foregoing, however, Tenant may sublet
this lease to an affiliate, parent or subsidiary of Tenant without Landlord's
consent. If Tenant, or any Guarantor, is a corporation, unincorporated
association or partnership, then the transfer, assignment or hypothecation of
any stock or interest in such corporation, association or partnership so as to
result in a change in the control thereof by the person, persons or entities
owning a controlling interest therein as of the date of this Lease, without the
prior written consent of Landlord as described above, shall be deemed an
assignment made in breach of this covenant. Landlord's consent in any specific
instance to any assignment, mortgage, encumbrance, subletting or use of the
Leased Premises and its collection and acceptance of rent from any such approved
assignee, subtenant or other occupant shall neither constitute a waiver of the
provisions of this paragraph, nor be construed as permission for any subsequent
assignment, mortgage, encumbrance, subletting or use without compliance with
this paragraph. Without the prior written consent of Landlord, this Lease and
the interest of Tenant, or any assignee of Tenant, shall not pass by operation
of law, nor shall it be subject to garnishment or sale under execution in any
suit or proceeding which may be brought against or by Tenant, or any assignee of
Tenant. No permitted assignment or sublease or collection of rent from an
approved assignee or subtenant shall relieve Tenant of its obligations
hereunder. Landlord shall have the right at any time to assign this Lease, in
whole or in part, to any third party.

                                       16

however, that while a case in which Tenant is the subject debtor under the
Bankruptcy Code is pending, Landlord shall not exercise its rights and remedies
pursuant to Section 20 so long as (1) the Bankruptcy Code prohibits the exercise
of such rights and remedies, and (2) Tenant or its Trustee in Bankruptcy
(hereinafter referred to as "Trustee") (i) cures all defaults under this Lease,
(ii) compensates Landlord for monetary damages incurred as a result of such
defaults, (iii) provides adequate assurance of future performance on the part of

due, where such failure continues for ten (10) days after notice thereof from
Landlord, provided, however, that Landlord need provide such notice no more than
three (3) times in any twelve (12) month period, and the fourth such default in
a twelve month period shall be deemed a default by Tenant without such notice
from Landlord;

                                       17


<PAGE>




      (g) A failure by Tenant to observe and perform any other term, covenant,
agreement or condition of this Lease to be observed or performed by Tenant,
where such failure continues for ten (10) business days after notice thereof
from Landlord, provided, however, that if the nature of the default is such that
the same cannot be reasonably be cured within the ten (10) business day period
allowed, Tenant shall not be deemed to be in default if Tenant shall, within
such ten (10) business day period, commence to cure and there after diligently
prosecute the same to completion. Nonetheless, Tenant will be deemed to be in
default if the same default is not cured within sixty (60) days after that
reasonable effort commences. Landlord shall not, however, be required to give
such notice if Tenant's failure to perform constitutes a non-curable breach of
this Lease. The notice required by this Paragraph is intended to satisfy any and
all notice requirements imposed by law on Landlord and is not in addition to any
such requirement;

      (h) Any material misrepresentation by Tenant to Landlord in connection
with the negotiation or execution of this Lease;

      (i) A default by Tenant under any other lease or sublease for any other
space in the Building, which has resulted in the termination of said lease;

      (j) Failure by any surety or guarantor of this Lease to comply with all
the provisions of the suretyship or guaranty agreement; or

      (k) The merger of any corporate surety or corporate guarantor of this
Lease with another entity, or the liquidation or dissolution of such surety or
guarantor or the change of control of such surety or guarantor caused by the
transfer of stock of such surety or guarantor, except by reason of the death of
any shareholder thereof.

20. Landlord's Rights Upon Tenant's Default. Upon default by Tenant of any of
the terms or covenants of this Lease, then in addition to any other remedies
available to Landlord herein at law or in equity, Landlord shall be entitled to
remedy such default as follows:

      (a) Re-Entry. Landlord shall have the right, immediately or at any time
thereafter, without further notice to Tenant (unless otherwise provided herein),
to enter the Leased Premises (breaking open locked doors, if necessary, and
using as much reasonable force as necessary to effect the manner thereof),
without terminating this Lease or being guilty of trespass, and do any and all
acts as Landlord may deem necessary, proper or convenient to cure such default,
for the account and at the expense of Tenant, and Tenant agrees to pay to
Landlord as Additional Rent all damage and/or expense incurred by Landlord in so
doing, including interest at the Penalty Rate, from the due date until the date
payment is received by Landlord. Landlord shall not be liable for any loss,
injury or damage resulting in any way from such action by Landlord.

      (b) Termination. Landlord shall have the right to terminate this Lease and
Tenant's right to possession of the Leased Premises and, with or without legal
process, take possession of the Leased Premises and remove Tenant, any occupant
and any property therefrom, using such force as may be necessary, without being
guilty of trespass and without relinquishing any rights of Landlord against
Tenant. Landlord shall be entitled to recover damages from Tenant in an amount
equal to the amount herein covenanted to be paid as Minimum Annual Rent during
the remainder of the Lease Term, said Minimum Annual Rent and Additional Rent
for the full term then remaining having been fully accelerated at the option of

                                       18


<PAGE>




Landlord, together with (i) all expenses of any proceedings (including, but not
limited to, legal expenses and reasonable attorney's fees) which may be
necessary in order for Landlord to recover possession of the Leased Premises,
(ii) the expenses of the re-renting of the Leased Premises (including, but not
limited to, any commissions paid to any real estate agent, advertising expense
and the costs of such alterations, repairs, replacements and decoration or
re-decoration as Landlord, in its sole judgment, considers advisable and
necessary for the purpose of re-renting the Leased Premises), and (iii) interest
computed at the Penalty Rate from the due date until paid; provided, however,
that there shall be credited against the amount of such damages all amounts
received by Landlord from such re-renting of the Leased Premises and such
amounts shall be refunded to Tenant.

      Landlord shall use its best efforts to re-rent the Premises, but Landlord
has no obligation to favor the Leased Premises over any other space available
for lease in the Building, and Landlord shall in no event be liable in any way
whatsoever for failure to re-rent the Leased Premises or, in the event that the
Leased Premises are re-rented, for failure to collect the rent thereof under
such re-renting. No act or thing done by Landlord shall be deemed to be an
acceptance of a surrender of the Leased Premises, unless Landlord shall execute
a written agreement of surrender with Tenant. Tenant's liability hereunder shall
not be terminated by the execution of a new lease of the Leased Premises by
Landlord. In the event Landlord does not exercise its option to accelerate the
payment of Minimum Annual Rent and Additional Rent as provided hereinabove, then
Tenant agrees to pay to Landlord, upon demand, the amount of damages herein
provided after the amount of such damages for any month shall have been
ascertained; provided, however, that any expenses incurred by Landlord shall be
deemed to be a part of the damages for the month in which they were incurred.
Separate actions may be maintained each month or at other times by Landlord
against Tenant to recover the damages then due, without waiting until the end of
the term of this Lease to determine the aggregate amount of such damages. Tenant
hereby expressly waives any and all rights of redemption granted by or under any
present or future laws in the event of Tenant being evicted or being
dispossessed for any cause, or in the event of Landlord obtaining possession of
the Leased Premises by reason of the violation by Tenant of any of the covenants
and conditions of this Lease.

      (c) Distress. Upon any default by Tenant in the payment of Minimum Annual
Rent or Additional Rent, Landlord shall have the right, without notice, fifteen
(l5) days after payment of such sum was due, to institute an action of distress
therefor, and, upon distress, in Landlord's discretion, this tenancy shall
terminate. In the event of such termination, the provisions of Section 20(b)
shall be applicable.

      (d) Lien for Rent. Upon any default by Tenant in the payment of Minimum
Annual Rent or Additional Rent, Landlord shall have a lien upon the property of
Tenant in the Leased Premises for the amount of any unpaid Minimum Annual Rent
or Additional Rent. In such event, Tenant shall not remove any of Tenant's
property from the Leased Premises except with the prior written consent of
Landlord, and Landlord shall have the right and privilege, at its option, to
take possession of all property of Tenant in the Leased Premises, to store the
same on the Leased Premises, or to remove it and store it in such place as may
be selected by Landlord, at Tenant's risk and expense.

      (e) No Future Lease Rights. If at any time during the term of this Lease
Tenant has been in default beyond Tenant's right to cure period, then,
regardless of whether Tenant is in default at the time of any option or future
right, all of

                                       19


<PAGE>




Tenant's present and future rights to this Lease are then terminated when the
default occurs.

      (f) Utilities and Services. Upon any default by Tenant, Landlord may
immediately cease to provide all utilities and services to the Leased Premises
as provided under Section 11 herein.

      (g) Landlord's Remedies Cumulative. All rights and remedies of Landlord
herein enumerated shall be cumulative, and none shall exclude any other right or
remedy allowed by law. For the purposes of any suit brought or based hereon,
this Lease shall be construed to be a divisible contract, to the end that
successive actions may be maintained on this Lease as successive periodic sums
mature hereunder.

21.   Lender Requirements.

       (a) Subordination. Tenant agrees that this Lease is subject and
subordinate to any and all ground or underlying leases and to the lien of any
first mortgages or deeds of trust now on or which at any time may be made a lien
upon the Building, or any part thereof, and to all advances made or hereafter to
be made upon the security thereof. This subordination provision shall be
self-operative and no further instrument of subordination shall be required.
Tenant agrees to execute and deliver, upon request, within five (5) days demand
by Landlord, such further instrument or instruments confirming this
subordination as shall be desired by Landlord or by any mortgagee or proposed
mortgagee; and Tenant hereby constitutes and appoints Landlord as Tenant's
attorney-in-fact to execute any such instrument or instruments. Upon Tenant's
written request, Landlord shall use its best efforts to acquire from any such
mortgagee an agreement that any proceeding to foreclose, sell or any other
action taken under the mortgage shall not affect Tenant's rights to continue to
occupy the Leased Premises and exercise and enjoy all of its rights hereunder so
long as Tenant complies with the terms and provisions of this Lease, and
continues to make the payments required hereunder to the appropriate designated
party, provided, Landlord's failure to acquire such an agreement shall not
mitigate Tenant's obligations hereunder. Tenant further agrees that, at the
option of the holder of any first mortgage or of the trustee under any first
deed of trust, this Lease may be made superior to said first mortgage or first
deed of trust by the insertion therein of a declaration that this Lease is
superior thereto.

      (b) Attornment. In the event any proceedings are brought for the
foreclosure of, or in the event of exercise of the power of sale under, any deed
to secure debt given by Landlord and covering the Leased Premises, Tenant shall
attorn to the purchaser upon any such foreclosure or sale and recognize such
purchaser as the owner and landlord under this Lease.

      (c) Financing. This Lease is subject to the approval of the mortgage
lender(s) providing mortgage financing for the Building, and disapproval of this
Lease by any such mortgage lender shall result in termination of this Lease. In
the event that any mortgage lender providing mortgage financing for the Building
requires, as a condition of such financing, that modifications to this Lease be
obtained, and provided that such modifications (i) are reasonable, (ii) do not
adversely affect Tenant's use of the Leased Premises as herein permitted, (iii)
do not materially alter the approved plans for the Basic Work and Additional
Work and (iv) do not increase the rentals and other sums required to be paid by
Tenant hereunder, then Landlord may submit to Tenant a written amendment to this
Lease incorporating such required modifications, and, in the event Tenant does
not

                                       20


<PAGE>




execute and return to Landlord such written amendment within ten (10) days after
the same has been submitted to Tenant, then Landlord shall thereafter have the
right, at its sole option, to terminate this Lease. Such option shall be
exercisable by Landlord giving Tenant written notice of termination, immediately
whereupon this Lease shall be terminated, and money or security therefor
deposited by Tenant with Landlord shall be returned to Tenant, and both Landlord
and Tenant shall thereupon be relieved from any and all further liability or
obligation hereunder.

       (d) Financial Statements. Tenant agrees, not more often than once per
calendar year, upon written notice by Landlord, to deliver to Landlord such
financial statements detailing its profits and losses, certified by a duly
authorized officer of Tenants if Tenant.

22. Estoppel Certificates. Tenant agrees, at any time and from time to time,
upon not less than ten (10) days prior written notice by Landlord, to execute,
acknowledge and deliver to Landlord a written estoppel certificate (i)
certifying that this Lease is unmodified and in full force and effect (or if
there have been modifications, stating the nature of same), (ii) stating the
Rent Commencement Date of the Lease Term, (iii) stating the amounts of Minimum
Annual Rent and Additional Rent and the dates to which the Minimum Annual Rent
and Additional Rent have been paid by Tenant, (iv) stating the amount of any
Security Deposit, (v) stating whether or not to the best knowledge of Tenant,
Landlord is in default in the performance of any covenant, agreement or
condition contained in this Lease, and, if so, specifying each such default of
which Tenant may have knowledge, (vi) stating that Tenant has no right to set
off and no defense against payment of the Minimum Annual Rent or Additional
Rent, (vii) address to which notices to Tenant should be sent. and (viii)
certifying such other matters as may be requested by Landlord. Any such
certificate delivered pursuant hereto may be relied upon by an owner of the
Building, any prospective purchaser of the Building, any mortgagee or
prospective mortgagee of the Building or of Landlord's interest therein, or any
prospective assignee of any such mortgage. Failure to deliver the aforesaid
certificate within the five (5) days shall be conclusive upon Tenant for the
benefit of Landlord and any successor to Landlord that this Lease is in full
force and effect and has not been modified except as may be represented by the
party requesting the certificate. Tenant shall be liable for any loss incurred
by Landlord resulting from Tenant's failure to timely execute and deliver any
estoppel certificate requested by Landlord, and shall reimburse Landlord for the
amount of any such loss upon demand, as Additional Rent.

23. Damage by Fire or Other Casualty. If the Leased Premises, or any other
portion of the Building shall, through no fault of Tenant or Tenant's agents,
servants, employees, customers, contractors, visitors or liscencees, be damaged
by fire, the elements, unavoidable accident or other casualty:

      (a) Except as otherwise provided in subparagraph (b) hereof, Landlord, at
Landlord's expense, shall promptly restore the Leased Premises, and Tenant, at
Tenant's sole expense, shall promptly restore all leasehold improvements
installed in the Leased Premises by Tenant or at Tenant's request and its own
furniture, furnishings, trade fixtures and equipment and the rent shall not be
abated. No penalty shall accrue for reasonable delay which may arise by reason
of adjustment of insurance on the part of Landlord, or on account of labor
problems, or any other cause beyond Landlord's reasonable control. If the damage
or destruction is such as to make the Leased Premises or any substantial part
thereof untenantable (in Landlord's judgment), and provided that such damage or
destruction is not due in whole or part to the act or omission of Tenant or

                                       21


<PAGE>




Tenant's agents, employees or invites, the Minimum Annual Rent shall abate
proportionately (based on proportion of the number of square feet rendered
untenantable to the total number of square feet of the Leased Premises), from
the date of the damage or destruction until the date the Leased Premises has
been restored by Landlord.

      (b) If the Leased Premises are substantially damaged or are rendered
substantially untenantable by fire or other casualty, or if Landlord's architect
certifies that the Leased Premises cannot be repaired within one hundred twenty
(120) working days of normal working hours, said period commencing with the
start of the repair work, or if Landlord shall decide not to restore or repair
the same, or if more than fifty percent (50%) of the gross leasable area of the
Building is rendered untenantable (even if the Leased Premises is undamaged) or
if Landlord shall decide to demolish the Building or not to rebuild it, then
Landlord may, within ninety (90) days after such fire or other casualty,
terminate this Lease by giving Tenant a notice in writing of such decision, and
thereupon the term of this Lease shall expire on the date specified in such
notice, or, if not date is so specified, by lapse of time upon the third day
after such notice is given, and Tenant shall vacate the Leased Premises and
surrender the same to Landlord. Upon the termination of this Lease under the
conditions hereinbefore provided, Tenant's liability for Minimum Annual Rent and
Additional Rent shall cease as of the day following the casualty.

      (c) The proceeds payable under all casualty insurance policies maintained
by Landlord on the Leased Premises shall belong to and be the property of
Landlord, and Tenant shall not have any interest in such proceeds. Tenant agrees
to look to Tenant's casualty insurance policies for the restoration and
replacement of the leasehold improvements installed in the Leased Premises by
Tenant or at Tenant's request and Tenant's fixtures, equipment and furnishings
in the Leased Premises, and in the event of termination of this Lease, for any
reason, following any such damage or destruction, Tenant shall promptly assign
to Landlord or otherwise pay to Landlord, upon Landlord's request, the proceeds
of said insurance and such other additional funds so that the total amount
assigned and/or paid by Tenant to Landlord shall be sufficient to restore
(whether or not any such restoration is actually to occur) all improvements,
fixtures, equipment and furnishings (excepting only Tenant's trade fixtures and
equipment) existing in the Leased Premises immediately prior to such damage or
destruction.

      (d) Notwithstanding anything to the contrary in this Section 23 or in any
other provision of this Lease, any obligation (under this Lease or otherwise) of
Landlord to restore all or any portion of the Leased Premises shall be subject
to Landlord's receipt of approval of the same by the mortgagee(s) of Landlord
(and any other approvals required by applicable laws), as well as receipt from
any such mortgagee(s) of such fire and other hazard insurance policy proceeds as
may have been assigned to any such mortgagee; it being agreed that if Landlord
has not received such approval(s) and proceeds within one hundred and eighty
(180) days after any such casualty, then Landlord shall have the option to
terminate this Lease, at any time thereafter, upon notice to Tenant.

24. Condemnation. In the event the whole or a substantial part of the Leased
Premises or the Building shall be taken for any public or quasi-public purpose
by any lawful power or authority by exercise of the right of appropriation,
condemnation or eminent domain, or sold to said authority to prevent such taking
(collectively referred to herein as a "taking"), Landlord shall have the right
to terminate this Lease effective as of the date possession is required to be
surrendered to said authority, and the Minimum Annual Rent and Additional Rent

                                       22


<PAGE>




shall be apportioned as of the date. For purposes of this section, a substantial
part of the Leased Premises or the Building shall be considered to have been
taken if, in Landlord's opinion, the taking shall render it commercially
undesirable for Landlord to permit this Lease to continue or to continue
operating the Leased Premises or the Building. Tenant shall not assert any claim
against Landlord or the taking authority for any compensation arising out of or
related to such taking and Landlord shall be entitled to receive the entire
amount of any award without deduction for any estate or interest of Tenant. If
Landlord does not elect to terminate this Lease, the Minimum Annual Rent and
Additional Rents shall be adjusted (based on the ratio that the number of square
feet of rentable area taken from the Leased Premises bears to the number of
rentable square feet in the Leased Premises immediately prior to such taking) as
of the date possession is required to be surrendered to said authority. Nothing
contained in this section shall be deemed to give Landlord any interest in any
award made to Tenant for the taking of personal property and fixtures belonging
to Tenant, as long as such award is made in addition to and separately stated
from any award made to Landlord for the Leased Premises or the Building.
Landlord shall have no obligation to contest any taking.

25. Landlord's Reserved Rights. The Landlord reserves the following rights:

      (a) To decorate, remodel, repair, alter or otherwise prepare the Leased
Premises for reoccupancy during the last ninety (90) days of the Lease Term, if
during or prior to that time Tenant vacates the Leased Premises; and

      (b) To show the Leased Premises to prospective tenants or brokers during
the last one hundred eighty (180) days of the term of this Lease, and to show
the Leased Premises to prospective purchasers, mortgagee, or assignee of any
mortgage on the Building at all reasonable times provided that reasonable prior
notice is given to Tenant in each case and that Tenant's use and occupancy of
the Leased Premises shall not be materially inconvenienced by any such action of
Landlord.

26.   Landlord and Tenant Liability.

       (a) Landlord's Liability. It is understood and agreed that Landlord is a
Maryland limited partnership and/or joint venture and that no partner of the
partnership, as may now or hereinafter be constituted, shall have liability to
Tenant or any person claiming under, by or through Tenant on any action, claim,
suit or demand brought pursuant to the terms and conditions of this Lease or
arising out of the occupancy by the Tenant of the Leased Premises. Landlord, or
its agents, shall not be responsible or liable to the Tenant or its agents,
employees, contractors, customers or other visitors for any injury or damage
resulting from acts or omissions of persons occupying property adjoining the
Leased Premises, or any part of the Building of which the Leased Premises are a
part, or for any injury or damage to persons or property resulting from fire,
explosion, falling plaster, steam, gas, electricity, water, rain, dampness or
snow or leaks from or through any part of the Leased Premises or the Building,
including the roof, or from the pipes, conduits, appliances or plumbing works,
or from the roof, street or subsurface or from any other place or by dampness or
by any other cause of whatsoever nature, unless caused by or due to the gross
negligence of Landlord, its agents, servants, or employees. All personal
property and equipment located in the Leased Premises shall be at the risk of
Tenant.

      (b) Tenant's Liability. Tenant shall reimburse Landlord for all expense,
damages or fines, incurred or suffered by Landlord by reason of any breach,
violation or nonperformance by Tenant, or its agents, servants, or employees, of

                                       23


<PAGE>




any material covenant or material provision of this Lease or the Rules and
Regulations promulgated by Landlord hereunder from time to time, or by reason of
damage to persons or property caused by moving property of or for Tenant in or
out of the Building, or by the installation or removal of furniture or other
property of or for Tenant, or by reason of or arising out of the carelessness,
negligence or improper conduct of Tenant, or its agents, servants, employees,
invites or licensees in the use or occupancy of the Leased Premises.

      (c) Indemnity. Tenant shall indemnify Landlord and its agents and
employees and save them harmless from and against any and all claims, actions,
damages, liabilities and expenses in connection with loss of life, personal
injury and/or damage to property (i) arising from or out of the occupancy or use
by Tenant of the Leased Premises or any part thereof, or (ii) occasioned wholly
or in part by any act or omission of the Tenant, its agents, contractors,
employees, servants, invites or licensees, whether inside the Leased Premises or
elsewhere in the Building; provided, however, that this indemnification shall
not apply to any such injury, loss, damage or liability arising from any
omission, fault, negligence, or misconduct on the part of the Landlord, its
agents, servants, employees, contractors or licensees. In the event that
Landlord or its agents and employees shall, without fault on its or their part,
be made a party to any litigation commenced by or against Tenant, then Tenant
shall protect and hold the same harmless and shall pay all costs, expenses and
reasonable attorneys' fees incurred or paid in connection with such litigation.

      (d) Criminal Acts of Third Parties. Landlord shall not be liable in any
manner to Tenant, its agents, employees, licensees, invitees or contractors for
any injury or damage to Tenant, Tenant's agents, employees, licensees, invites,
or contractors or their property caused by the criminal or intentional
misconduct of third parties. All claims against Landlord for any such damage or
injury are hereby expressly waived by Tenant, and Tenant hereby agrees to hold
harmless and indemnify Landlord from all such damages and the expense of
defending all claims made by Tenant's agents, employees, licensees, invitees or
contractors arising out of such acts.

27.   Tenant's Insurance.

       (a) Coverages. Tenant shall have issued, pay the premiums therefor, and
maintain in full force and effect during the Lease Term:

              (i) Commercial General Liability. A commercial general liability
insurance policy or policies (providing among other coverages: Blanket
Contractual, Personal Injury, independent Contractors, Products/Completed
Operations Hazard, Automobile Liability/Comprehensive Form, and Workers
Compensation) in which the Landlord (and such additional persons and/or entities
as Landlord may request) and Tenant shall be the insured, naming the Landlord
(and such additional persons and/or entities as Landlord may request) and Tenant
as insured parties in the amount of Two Million and No/100 Dollars
($2,000,000.00) combined single limit general liability coverage for bodily
injury or property damage, which amount may be increased from time to time by
the Landlord in its reasonable determination;

              (ii) All-Risk Property. All-risk property insurance, including
theft, naming Landlord (and such additional persons and/or entities as Landlord
may request) and Tenant as insured, written at replacement cost value and with
replacement cost endorsement, covering all leasehold improvements installed in
the Leased Premises by Tenant or at Tenant's request and all of Tenant's
personal

                                       24


<PAGE>




property in the Leased Premises (including, without limitation, inventory, trade
fixtures, floor coverings, furniture and other property removable by Tenant
under the provisions of this Lease);

              (iii) Workers' Compensation. If and to the extent required by law,
workers' compensation and employer's liability or similar insurance in form and
amounts required by law; and

              (iv) Additional Insurance. Such additional insurance as any
mortgagee of the Building may require.

      (b) Policy Requirements. In the event Tenant shall fail to provide such
insurance, or shall fail to pay the premiums when due, Landlord shall have the
right to cause such insurance to be issued and to pay the premiums therefor, or
any premiums in default, and to collect same as Additional Rent together with
interest at the Penalty Rate on the amount of such premiums from the date of
payment by Landlord until the date of repayment by Tenant. All such policies
shall contain only such reasonable deductible amounts as may be approved in
advance by Landlord and shall contain a provision that Landlord shall receive
not less than thirty (30) days advance notice in writing from the insurance
company of any intention of the insurance company to cancel such policy or
policies. Tenant shall provide written evidence to Landlord of its acquisition
of such policies no later than ten (10) days prior to the commencement of this
Lease and prior to any renewal date of such policies. All policies shall be
carried with an insurance company qualified to do business in the State of
Maryland, and rated A or better by the A.M. Best Company.

      (c) No Limitation of Liability. Neither the issuance of any insurance
policy required under this Lease nor the minimum limits specified herein shall
be deemed to limit or restrict in any way Tenant's liability arising under or
out of this Lease.

      (d) Notice of Fire and Accident. Tenant shall give Landlord immediate
notice in case of fire, theft, or accidents in the Leased Premises, and in case
of fire, theft or accidents in the Building if involving Tenant, its agents,
employees or invitees.

28. Waiver of Subrogation. Landlord and Tenant mutually covenant and agree that
each party, in connection with insurance policies required to be furnished in
accordance with the terms and conditions of this Lease, or in connection with
insurance policies which they obtain insuring such insurable interest as
Landlord or Tenant may have in its own properties, whether personal or real,
shall expressly waive any right of subrogation on the part of the insurer
against the Landlord (and any mortgagee requested by Landlord) or Tenant as the
same may be applicable, which right to the extent not prohibited or violative of
any such policy is hereby expressly waived, and Landlord and Tenant each
mutually waive all right of recovery, claims, losses and/or damages against each
other, their agents, or employees for any loss, damage or injury of any nature
whatsoever to property or person for which either party is required by this
Lease to carry insurance.

29. No Liens Permitted: Discharged. Tenant will not permit to be created or to
remain undischarged any lien, encumbrance or charge (arising out of any work
done or materials or supplies furnished, or claimed to have been done or
furnished, by any contractor, mechanic, laborer or materialman or any mortgage,
conditional sale, security agreement or chattel mortgage, or otherwise by or for
Tenant)

                                       25


<PAGE>




which might be or become a lien or encumbrance or charge upon the Building or
any part thereof or the income therefrom. Tenant will not suffer any other
matter or thing whereby the estate, rights and interests of Landlord in the
Building or any part thereof might be impaired. If any lien, or notice of lien
on account of an alleged debt of Tenant or any notice of contract by a party
engaged by Tenant or Tenant's contractor to work on the Leased Premises shall be
filed against the Building or any part thereof, Tenant, within fifteen (15) days
after notice of the filing thereof, will cause the same to be discharged of
record by payment, deposit, bond, order of a court of competent jurisdiction or
otherwise. If Tenant shall fail to cause such lien or notice of lien to be
discharged within the period aforesaid, then, in addition to any other right or
remedy, Landlord may, but shall not be obligated to, discharge the same either
by paying the amounts claimed to be due or by procuring the discharge of such
lien by deposit or by bonding proceedings and in any such event Landlord shall
be entitled, if Landlord so elects, to compel the prosecution of an action for
the foreclosure of such lien by the lienor and to pay the amount of the judgment
in favor of the lienor with interest, costs and allowances. Any amount so paid
by Landlord and all costs and expenses, including attorneys' fees, incurred by
Landlord in connection therewith, shall constitute Additional Rent payable by
Tenant under this Lease and shall be paid by Tenant to Landlord on demand.
Nothing herein contained shall obligate Tenant to pay or discharge any lien
created by Landlord.

30. Signs and Advertisements. Landlord shall provide for Tenant, at Landlord's
expense, a notice in the Building directory, Building street sign, and a sign
for the entrance door to the Leased Premises in the type and manner Landlord
from time to time provides for tenants of the Building. No other sign,
advertisement, notice or any other thing of any kind whatsoever shall be
inscribed, painted, affixed or displayed in or about the Building by Tenant and
if any such sign, advertisement or notice is exhibited, Landlord shall have the
right to remove the same and Tenant shall be liable for any and all expenses
incurred by Landlord for said removal. Tenant agrees to maintain its entrance
door or entry sign in good condition and repair at all times.

31. Notices. All notices to be given under this Lease shall be in writing,
hand-delivered, sent by Federal Express, or mailed by United States Certified or
Registered Mail, postage prepaid. Notices should be delivered as follows:

      (a)     To the Landlord at the address specified in Section 1(a)(18).

      (b) To the Tenant at the addresses specified in Sections l(a)(17).

Any such notice shall be deemed to be served on the date it is hand-delivered or
delivered by Federal Express, or on the third day after the date on which it is
deposited in the U.S. mails. Landlord and Tenant shall each have the right to
change the person and/or address to which notices shall be delivered upon
written notice thereof to the other party sent pursuant to the provisions of
this paragraph.

32. Time. Landlord and Tenant acknowledge that time is of the essence in the
performance of any and all obligations, terms, and provisions of this Lease.

33. Postponement of Performance. In the event that either party hereto shall be
delayed or hindered in or prevented from the performance of any act required
hereunder by reason of strikes, labor troubles, inability to procure labor or
materials, failure of power, restrictive governmental laws or regulations,
riots, insurrection, war, acts of God, fire or other casualty or other reason of
a

                                       26


<PAGE>




similar or dissimilar nature beyond the reasonable control of the party delayed
in performing work or doing acts required under the terms of this Lease, then
performance of such act shall be excused for the period of the delay and the
period for the performance of any such act shall be extended for a period
equivalent to the period of such delay. The provisions of this paragraph shall
not operate to excuse Tenant from the prompt payment of Minimum Annual Rent or
Additional Rent and shall not operate to extend the term of this Lease. Delays
or failures to perform resulting from lack of funds shall not be deemed delays
beyond the reasonable control of a party.

34. No Waiver. No provision of this Lease shall be deemed to have been waived by
Landlord, unless such waiver be in writing signed by Landlord. No waiver by
Landlord of any breach by Tenant of any of the terms, covenants, agreements, or
conditions of this Lease shall be deemed to constitute a waiver of any
succeeding breach thereof, or a waiver of any breach of any of the other terms,
covenants, agreements, and conditions herein contained.

        No employee of Landlord or of Landlord's agents shall have any authority
to accept the keys of the Leased Premises prior to termination of the Lease, and
the delivery of keys to any employee of Landlord or Landlord's agents shall not
operate as a termination of the Lease or a surrender of the Leased Premises. The
receipt by Landlord of any payment of Minimum Annual Rent or Additional Rent
with knowledge of the breach of any covenant of this Lease shall not be deemed a
waiver of such breach. The failure of Landlord to enforce any of the Rules and
Regulations made a part of this Lease, or hereafter adopted, against Tenant or
any other tenant in the Building shall not be deemed a waiver of any such Rules
and Regulations.

35. Limitation of Landlord's Liability. In consideration of the benefits
accruing hereunder, Tenant and all successors and assigns of Tenant covenant and
agree that in the event of any actual or alleged failure, breach or default
hereunder by Landlord: (a) the sole and exclusive remedy shall be against the
interest of Landlord in the Building of which the Leased Premises are a part;
(b) neither Landlord nor any partner of Landlord shall be personally liable with
respect to any claim arising out of or related to this Lease; (c) no partner of
Landlord shall be sued or named as a party in any suit or action (except as may
be necessary to secure jurisdiction of Landlord); (d) no service of process
shall be made against any partner of Landlord (except as may be necessary to
secure jurisdiction of Landlord); (e) any judgment granted against any partner
of Landlord may be vacated and set aside at any time as if such judgment had
never been granted; and (f) these covenants and agreements are enforceable both
by Landlord and also by any partner of Landlord.

36. Transfer of the Building. In the event of the sale or other transfer of
Landlord's right, title and interest in the Leased Premises or the Building
(except in the case of a sale-leaseback financing transaction in which Landlord
is the lessee), Landlord shall transfer and assign to such purchaser or trans-
feree all amounts of pre-paid Minimum Annual Rent, and Landlord thereupon and
without further act by either party hereto shall be released from all liability,
obligations, and covenants, express or implied, hereunder derived from this
Lease arising out of any act, occurrence or omission relating to the Leased
Premises or this Lease occurring after the consummation of such sale or
transfer, provided that the transferee shall assume all of Landlord's
obligations hereunder from the date of such transfer. Tenant shall have no right
to terminate this Lease nor to abate Minimum Annual Rent nor to deduct from, nor
set-off, nor counterclaim against Minimum Annual Rent because of any sale or
transfer (including, without

                                       27


<PAGE>




limitation, any sale-leaseback) by Landlord or its successors or assigns. This
lease shall not be affected by any such sale, and Tenant agrees to attorn to the
purchaser or transferee. Upon any sale or other transfer as above provided
(other than a sale-leaseback), or upon any assignment of Landlord's interest
herein, it shall be deemed and construed conclusively, without further agreement
between the parties, that the purchaser or other transferee or assignee has
assumed and agreed to perform the obligations of Landlord thereafter accruing.

37. Waiver of Counterclaim and Trial by Jury. Landlord and Tenant waive their
right to trial by jury in any action, proceeding or counterclaim brought by
either of the parties hereto against the other (except for personal injury or
property damage) on any matters whatsoever arising out of or in any way
connected with this Lease, the relationship of Landlord and Tenant, Tenant's use
of or occupancy of the Leased Premises, and any emergency statutory or any other
statutory remedy. Tenant shall not interpose any counterclaim or counterclaims
or claims for set-off, recoupment or deduction of Minimum Annual Rent or
Additional Rent in a summary proceeding for nonpayment of Minimum Annual Rent or
Additional Rent or other action or summary proceeding based on termination,
holdover or other default in which Landlord seeks repossession of the Leased
Premises from Tenant.

38. Lease Recording. It is understood and agreed that Landlord shall not record
the within Lease Agreement among the Land Records of Baltimore County, Maryland,
for any purpose.

39. Notice of Default to Landlord and Mortgagee and Right to Cure. Tenant shall
give, by registered mail, a written notice of any failure by Landlord to perform
any of its obligations under this Lease to Landlord which shall specifically set
forth the nature of the nonperformance by the Landlord and shall give the
Landlord thirty (30) days within which to cure such default or non-performance.
However, if such default or non-performance reasonably requires more than thirty
(30) days to cure, Landlord shall not be in default if such cure is commenced
within such thirty (30) day period and thereafter diligently pursued to
completion. Said notice of default shall be a condition precedent to the
institution by Tenant of any judicial proceedings for nonperformance or default
against the Landlord. Tenant agrees to give any mortgagee and/or Trust Deed
Holders whose name and address have been furnished to Tenant in writing, by
registered mail, a copy of any notice of default served upon the Landlord.
Tenant further agrees that if Landlord shall fail to cure such default within
the time provided for in this Lease Agreement, then the mortgagees and/or Trust
Deed Holders shall have an additional thirty (30) days within which to cure such
default or, if such default cannot be cured within that time, then such
additional time as may be necessary if within such thirty (30) days, any
mortgagee and/or Trust Deed Holders has commenced and is diligently pursuing the
remedies necessary to cure such default, in which event this Lease shall not be
terminated while such remedies are being so diligently pursued.

construal, validity, performance and enforcement of this Lease.

or approval in its sole discretion unless otherwise specified herein.

      (h) Separability. If any term or provision of this Lease or applications
thereof to any person or circumstance shall, to any extent, be invalid or
unenforceable, the remaining terms and provisions of this Lease, or the
application of such term or provision to persons or circumstances other than

but all counterparts shall constitute one and the same legal document.

      (j) Authority. Landlord and Tenant hereby covenant each for itself, that

authorized to do so. If Tenant signs as a partnership, each of the persons
executing this Lease on behalf of Tenant does hereby covenant and warrant that

<PAGE>




but this Lease shall be interpreted in accordance with the general tenor of the
language in an effort to reach the intended result.

      (m) Entire Agreement; Modification. This Lease contains the entire
agreement between the parties, and any agreement hereafter made shall be
ineffective to change, discharge or effect an abandonment in whole or in part
unless such agreement is in writing and signed by the party against whom
enforcement of the change, modification, discharge or abandonment is sought.
Acceptance of, or acquiescence in, a course of performance rendered under this
or any prior agreement between the parties or their affiliates shall not be
relevant or admissible to determine the meaning of any term of this Lease.

      (n) Termination. This Lease and the tenancy hereby created shall cease and
determine at the end of the Lease Term, or any extension or renewal thereof,
without the necessity of any notice from either Landlord or Tenant to terminate
the same, and Tenant hereby waives notice to vacate the Leased Premises and
agrees that Landlord shall be entitled to the benefit of all provisions of law
respecting the summary recovery of possession of premises from a tenant holding
over to the same extent as if statutory notice had been given. For the period of
three (3) months prior to the expiration of the Lease Term or of any extension
or renewal thereof, Landlord shall have the right to show the Leased Premises

5:00 pm, on any day except Saturday and Sunday and except any legal holiday on
which Tenant shall not be open for business.

      (o) Corporate Approval. If Tenant is a corporation, Tenant covenants and
warrants that it has the requisite corporate approval to enter into and execute

practicable following execution of this Lease, a copy of an executed resolution
by its Board of Directors, authorizing the execution of the Lease Agreement and
authorizing the individual executing this Lease to execute said Agreement on
behalf of and in the name of the Corporation. If Tenant shall fail to provide
the executed resolution within the time period required under this Section,
Landlord may, at its option, declare this Lease to be null and void and of no
further force or effect. If Tenant is a corporation it acknowledges that this
Lease is executed under seal and that a twelve year period of limitation
applies.

      (p) Approval of Mortgage. This Lease is contingent upon the approval of
any and all mortgagees or other lenders of the Landlord. Landlord shall have
thirty (30) days from the execution of this Lease to obtain all necessary
approvals from this mortgagee or other lenders; and thereafter shall have the
right to extend said approval period an additional ten (10) days upon written
notice to Tenant. If said approvals cannot be obtained within the aforesaid
period, this Lease and the rights and duties of the parties hereunder, shall be
null and void and be of no further effect.

      (q) Zoning and Licensing Approvals. Anything herein elsewhere contained to
the contrary, this Lease and all the terms, covenants, and conditions hereof are
in all respect subject and subordinate to all zoning restrictions affecting the
Leased Premises, and the Building in which they are located, and the Tenant
agrees to be bound by such restrictions. The Landlord further does not warrant
that any license or licenses, permit or permits, which may be required for the
business to be conducted by the Tenant on the Leased Premises will be granted,
or, if granted, will be continued in effect or renewed, and any failure to
obtain

                                       30


<PAGE>




such licence or licences, permit or permits, or any revocation thereof or
failure to renew the same, shall not release the Tenant from its obligations
under this Lease Agreement.

41. Quiet Enjoyment. If and so long as Tenant pays rent and additional rent
reserved by this Lease, and performs and observes all the covenants and
provisions hereof, Tenant shall quietly enjoy the Leased Premises, subject,
however, to the terms and provisions hereof.

42. Remedies Cumulative. No mention in this Lease of any specific right or
remedy shall preclude Landlord from exercising any other right or from having
any other remedy, or from maintaining any action to which it may otherwise be
entitled, either at law or equity; and the failure of Landlord to insist in any
one or more instances upon a strict performance of any covenant of this Lease or
to exercise any option or right herein contained shall not be construed as a
waiver of relinquishment for the future of such covenant, right or option, but
the same shall remain in full force and effect unless the contrary is expressed
in writing by Landlord.

43. Binding Effect. This Agreement and the covenants and conditions herein
contained shall be binding upon and shall inure to the benefit of Landlord, its
heirs, personal representatives, successors and assigns, and shall be binding
upon Tenant, its heirs, personal representatives, successors and assigns, and
shall inure to the benefit of Tenant and only such assigns of Tenant to whom the
assignment by Tenant has been consented to by Landlord.

      IN WITNESS WHEREOF, the parties hereto have duly executed this Agreement
the day and year first above written.

       Section 3.2.5. Cancellation Fee. In the event the BORROWER terminates
the REVOLVING LOAN prior to August 31, 1999, the BORROWER shall pay to the

accrue on the entire principal balance of the TERM LOAN at a fixed annual rate
of interest equal to either the FIXED RATE or the COST OF FUNDS RATE, plus the
APPLICABLE MARGIN, all as determined on the date occurring two (2) BUSINESS DAYS
after the date the BORROWER provides the LENDER with written notice of such
election. In the event the BORROWER provides the LENDER with written notice of
its election to have interest accrue at a fixed rate of interest, interest shall
commence accruing at such fixed annual rate of interest on the date occurring
three (3) BUSINESS DAYS after the LENDER'S receipt of such written notice and
shall continue to accrue at such rate until the TERM LOAN is paid in full. The
TERM LOAN shall be repaid in accordance with the stated terms and conditions of
the TERM LOAN NOTE, which terms and conditions are incorporated herein by
reference.


<PAGE>




       Section 3.3.2. Purpose. The proceeds of the TERM LOAN shall be used
solely and exclusively for the purpose of refinancing certain existing
indebtedness over to Signet Bank, N.A.

       Section 3.4. Equipment Line. The LENDER agrees: (a) to extend to the
BORROWER, under the EQUIPMENT LINE, term loans from time to time in order to
finance the acquisition of items of EQUIPMENT, provided, that the principal
amount of any such term loan shall not exceed one hundred percent (100%) of the
lesser of (i) the fair market value for the EQUIPMENT purchased with such loan
advance, or (ii) the actual net invoice price paid by the BORROWER (less the
value of all rebates, trade-ins, and all shipping and installation costs) for
the EQUIPMENT purchased with such loan advance; and (b) to acquire, or cause
LEASECORP to acquire, items of EQUIPMENT selected by the BORROWER and lease, or
cause LEASECORP to lease, such items of EQUIPMENT to the BORROWER; provided,
however, that the aggregate of the principal amount of all term loans advanced

($1,500,000.00). The minimum amount of any term loan advanced under the
EQUIPMENT LINE shall be Ten Thousand Dollars ($10,000.00) and the minimum amount
of the LEASED EQUIPMENT COST in any single lease transaction shall be Ten
Thousand Dollars ($10,000.00).

       Section 3.4.1. Term. The EQUIPMENT LINE shall terminate, and the LENDER'S
obligations to make term loans and acquire equipment to be leased to the
BORROWER shall terminate, on September 30, 1999, unless such date is extended by
written agreement executed by the LENDER.

       Section 3.4.2. Term Loan Advances Under Equipment Line.

                  a. Equipment Notes. Each term loan advanced under the
EQUIPMENT LINE shall be evidenced by and shall be repaid in accordance with the
provisions of an EQUIPMENT NOTE in the form attached hereto as Exhibit A- 1, if
the BORROWER elects interest to accrue based on the LIBOR RATE, or Exhibit A-2,
if the BORROWER elects interest to accrue based on the FIXED RATE or the COST OF
FUNDS RATE, the terms and conditions of which are incorporated herein by
reference.

                  b. Requisition Procedure. Not less than two (2) BUSINESS DAYS
prior to the date upon which an advance is to be made under the EQUIPMENT LINE,
the BORROWER shall execute and deliver a fully completed Requisition in the form
attached hereto as Exhibit B, containing the specifics required therein relating
to the requested advance. On the date the LENDER is to make an advance of
proceeds under the EQUIPMENT LINE to the BORROWER, the BORROWER shall execute
and deliver to the LENDER an EQUIPMENT NOTE in the principal amount equal to the
sum of such term loan advance. The principal amount of each term loan advance
shall be repaid in even monthly principal installments over a term between three
and five years which shall be determined by the BORROWER and LENDER based on the
useful life of the EQUIPMENT purchased with such loan advance. The LENDER is
hereby authorized by the BORROWER to make any advances hereunder directly to the
persons or entities supplying the EQUIPMENT to the BORROWER that is the subject
of the requested advance.

                  c. Interest. Interest shall accrue on the unpaid principal
balance of each term loan made under the EQUIPMENT LINE, and be repaid, as


<PAGE>




follows:

                           (i)     Interest Rate.  Except as specifically set
forth below, interest shall accrue on the unpaid principal balance of each term
loan advanced under the EQUIPMENT LINE at a fluctuating annual rate of interest
equal to the LIBOR RATE, in effect from time to time, plus the APPLICABLE MARGIN
as of the date of the advance, with changes in such interest rate to be made
daily based upon changes in the LIBOR RATE. Notwithstanding the foregoing to the
contrary, the BORROWER shall have the right to elect to have interest accrue on
the entire principal balance of any term loan made under the EQUIPMENT LINE at a
fixed annual rate of interest equal to either the FIXED RATE or the COST OF
FUNDS RATE, plus the APPLICABLE MARGIN all as determined on the date of the
advance. The BORROWER must elect in writing to have interest accrue based on the
FIXED RATE or the COST OF FUNDS RATE not less than two (2) BUSINESS DAYS prior
to the date upon which such term loan advance is made under the EQUIPMENT LINE.

                           (ii)    Interest Payments.  The BORROWER shall make
payments of all accrued and unpaid interest on each term loan under the
EQUIPMENT LINE on the first BUSINESS DAY of each month, commencing on the first
BUSINESS DAY of the first month immediately following the date of the advance of
proceeds of such term loan, and continuing until all sums outstanding under the
term loan are paid in full.

       Section 3.4.3. Leases Under Equipment Line. Not less than ten (10)
BUSINESS DAYS prior to the date upon which the BORROWER desires the LENDER to
acquire (or cause LEASECORP to acquire) an item of EQUIPMENT to be leased to the
BORROWER, the BORROWER shall make a written request to the LENDER for the LENDER
or LEASECORP to enter into a lease transaction with the BORROWER pursuant to the
terms of this AGREEMENT and the BORROWER shall provide to the LENDER such
information as the LENDER may require in connection with the EQUIPMENT to be
leased and the seller of such EQUIPMENT. All LEASES entered into by and between
the LENDER or LEASECORP and the BORROWER shall be on terms and conditions
acceptable to both the BORROWER and the LENDER or LEASECORP, as the case may be,
and if the BORROWER and the LENDER or LEASECORP, as the case may be, cannot
agree to such terms and conditions, then neither the LENDER nor LEASECORP shall
have any obligation to acquire such EQUIPMENT and lease it to the BORROWER. All
LEASES shall constitute "Finance Leases" under the Maryland Uniform Commercial
Code, Title 2A, Commercial Law Article, Annotated Code of Maryland, as amended.

       Section 3.5. LIBOR Rate Availability. If after the date of this AGREEMENT
the LENDER determines at any time that the adoption of any law, rule or
regulation or change therein, or a change in the interpretation or
administration thereof by any governmental authority, central bank or comparable
agency charged with interpretation or administration thereof, or a change in
market conditions has made it impracticable or illegal for the LENDER to offer
interest rate pricing based on the LIBOR RATE, the LENDER shall notify the
BORROWER of its determination, and thereafter until the LENDER notifies the
BORROWER that such circumstances no longer exists: (a) the LENDER shall not be
obligated to offer interest rate pricing based on the LIBOR RATE; and (b) each
LOAN accruing interest based on the LIBOR RATE shall automatically commence to
accrue at a fluctuating rate of interest equal to the COM. PAPER RATE plus the
APPLICABLE MARGIN.


<PAGE>




       Section 3.6. Calculation Of Interest. Interest shall be calculated on the
unpaid principal balance of the LOANS on the basis of a three hundred sixty
(360) days per year factor applied to the actual days on which there exists an
unpaid balance thereunder.

       Section 3.7. Facility Fee. The BORROWER shall pay to the LENDER on or
before CLOSING a non-refundable and unconditional facility fee of Fifteen
Thousand Dollars ($15,000.00), which shall be the absolute property of the
LENDER upon payment. The facility fee shall not be considered to be a payment of
any of the LENDER'S expenses incurred in connection with the LOANS and shall be
paid independent of the amount of proceeds of the LOANS ultimately advanced to
the BORROWER, even if that amount is less than the stated principal amounts of
the LOANS.

       Section 3.8. Commitment Fee. For each three (3) month period ending on
the last calendar days of October, January, April and July, or portion thereof
during which the REVOLVING LOAN facility established hereunder is in existence
and has not been terminated, until the termination of the REVOLVING LOAN, the
BORROWER shall pay to the LENDER a commitment fee of: (a) one-quarter of one
percent (1/4%) per annum on that sum (only if such sum is positive) obtained by
subtracting the average daily disbursed principal balance of the REVOLVING LOAN
during such three (3) month period or portion thereof from Six Million Dollars
($6,000,000.00); plus (b) one-half of one percent (1/2%) per annum on that sum
obtained by subtracting (i) the greater of Zero or the amount by which the
average daily disbursed principal balance of the REVOLVING LOAN during such
three (3) month period or portion thereof exceeds Six Million Dollars
($6,000,000.00), from (ii) Two Million Five Hundred Thousand Dollars
($2,500,000.00); provided, however, that the amount of the commitment fee shall
be reduced for each three (3) month period ending after February 28, 1998, to
that amount equal to one-quarter of one percent (1/4%) per annum on that sum
obtained by subtracting the average daily disbursed principal balance of the
REVOLVING LOAN during the applicable three (3) month period or portion thereof
from the REVOLVER DOLLAR CAP, if, and only if, the BORROWER'S financial
statements for the fiscal quarter ending February 28, 1998 evidence that the
BORROWER is in full compliance with all of the financial covenants set forth in
this AGREEMENT and there are no DEFAULTS under this AGREEMENT as of February 28,
1998. The commitment fee shall be payable quarterly in arrears, on the fifteenth
day of each succeeding November, February, May, and August or on the last day of
a portion of a three (3) month period commencing with the first of such payments
to be made on November 15, 1997. The commitment fee is not to be considered a
fee being paid by the BORROWER to the LENDER as an inducement to the LENDER to
make advances, nor shall it be considered to modify or limit the ability of the
LENDER to terminate in accordance with the provisions of this AGREEMENT the
ability of the BORROWER to borrow under the REVOLVING LOAN.

       Section 3.9. Capital Adequacy. If at any time or from time to time the
LENDER determines that the adoption or implementation of any CAPITAL ADEQUACY
REQUIREMENT, or the compliance by the LENDER or any corporation controlling the
LENDER therewith, affects the amount of capital to be maintained by the LENDER
or any corporation controlling the LENDER as a result of its obligations
hereunder, or reduces the effective rate of return on the LENDER'S or such
corporation's capital to a level below that which the LENDER or such corporation
would have achieved but for such CAPITAL ADEQUACY REQUIREMENT as a


<PAGE>




consequence of its obligations hereunder (taking into consideration the LENDER'S
or such corporation's policies with respect to capital adequacy), then after
submission by the LENDER to the BORROWER of a written request therefor and a
statement of the basis for such determination, the BORROWER shall pay to the
LENDER such additional amounts as will compensate the LENDER for the cost of
maintaining the increased capital or for the reduction in the rate of return on
capital, together with interest thereon at the highest rate of interest then in
effect under the NOTES from the date the LENDER requests such additional amounts
until those amounts are paid in full; provided, however, the BORROWER shall have
no obligation to pay such amounts to the LENDER unless the need to increase
capital or the reduction in the rate of return on capital is due to a
deterioration in the financial condition of the BORROWER or the value of the
COLLATERAL or due to an EVENT OF DEFAULT.

       Section 3.10. Payments. All payments received by the LENDER which are to
be applied to reduce the OBLIGATIONS shall be credited to the balance due from
the BORROWER pursuant to the normal and customary practices of the LENDER, but
shall be provisional and shall not be considered final unless and until such
payment is not subject to avoidance under any provision of the United States
Bankruptcy Code, as amended, including Sections 547 and 550, or any state law
governing insolvency or creditors' rights. If any payment is avoided or set
aside under any provision of the United States Bankruptcy Code, including
Sections 547 and 550, or any state law governing insolvency or creditors'
rights, the payment shall be considered not to have been made for all purposes
of this AGREEMENT and the LENDER shall adjust its records to reflect the fact
that the avoided payment was not made and has not been credited against the
OBLIGATIONS.

       Section 3.11. Advancements. If the BORROWER fails to perform any of its
agreements or covenants contained in this AGREEMENT or if the BORROWER fails to
protect or preserve the COLLATERAL or the status and priority of the security
interest of the LENDER in the COLLATERAL, the LENDER may make advances to
perform the same on behalf of the BORROWER to protect or preserve the COLLATERAL
or the status and priority of the security interest of the LENDER in the
COLLATERAL, and all sums so advanced shall immediately upon advance become
secured by the security interests granted in this AGREEMENT, and shall become
part of the principal amount owed to the LENDER with interest to be assessed at
the applicable rate thereon and subject to the terms and provisions of this
AGREEMENT and all of the LOAN DOCUMENTS. The BORROWER shall repay on demand all
sums so advanced on the BORROWER'S behalf, plus all expenses or costs incurred
by the LENDER, including reasonable legal fees, with interest thereon at the
highest rate provided for in the LOAN DOCUMENTS. The provisions of this Section
shall not be construed to prevent the institution of the rights and remedies of
the LENDER upon the occurrence of an EVENT OF DEFAULT. The contrary
notwithstanding, the authorization contained in this Section shall impose no
duty or obligation on the LENDER to perform any action or make any advancement
on behalf of the BORROWER and is for the sole benefit and protection of the
LENDER.

                  q. All rights of the BORROWER as a secured party with respect
                     to collateral security now or hereafter securing any of the
                     obligations of third parties to the BORROWER, together with
                     all agreements and instruments evidencing or creating any

<PAGE>




       Section 4.2. Proceeds And Products. The LENDER'S security interests
provided for herein shall apply to the proceeds, including but not limited to
insurance proceeds, and the products of the COLLATERAL.

       Section 4.3. Priority Of Security Interest. Each of the security
interests granted by the BORROWER to the LENDER pursuant to this AGREEMENT shall
be a perfected first priority security interest in the COLLATERAL, except as
expressly agreed in advance to the contrary by the LENDER in writing.

       Section 4.4. Future Advances. The security interests granted by the
BORROWER to the LENDER hereunder shall secure all current and all future
advances made by the LENDER to the BORROWER, or for the account or benefit of
the BORROWER, and the LENDER may advance or readvance upon repayment by the
BORROWER all or any portion of the sums loaned to the BORROWER and any such
advance or readvance shall be fully secured by the security interests created by
the LOAN DOCUMENTS.

       Section 4.5. Receivable Collections. The BORROWER shall deposit into the
COLLECTION ACCOUNT, immediately upon receipt thereof, all cash, checks, drafts,
and other instruments for the payment of money, properly endorsed, which have
been received by the BORROWER in full or partial payment of any RECEIVABLE.
Prior to any such deposit by the BORROWER into the COLLECTION ACCOUNT, the
BORROWER will not commingle such items of payment with any of its other funds or
property but will hold them separate and apart. The BORROWER shall instruct all
of its ACCOUNT DEBTORS to make all payments on the BORROWER'S RECEIVABLES to a
post office box in which the LENDER alone shall have sole access ("LOCK BOX").
The LENDER shall, on each BUSINESS DAY, withdraw the items of payment from the
LOCK BOX and deposit them into either the COLLECTION ACCOUNT or the COMMERCIAL
ACCOUNT, as determined by the LENDER. The LENDER, from time to time, shall apply
all of the collected funds held in the COLLECTION ACCOUNT toward payment of all
or any part of the OBLIGATIONS, whether or not then due, in such order of
application as the LENDER may determine.

       Section 4.6. Collection Of Receivables By Lender. The LENDER, at any time
or from time to time, after the occurrence of a violation of the terms of
Section 4.5 hereof or after the occurrence of an EVENT OF DEFAULT, may terminate
the BORROWER'S authority to collect the RECEIVABLES. Upon a termination of the
BORROWER'S authority, the LENDER shall have the right to send notices of
assignment or notices of the LENDER'S security interest to any and all ACCOUNT
DEBTORS or any third party holding or otherwise concerned with any of the
COLLATERAL, and thereafter the LENDER shall have the sole right to collect the
RECEIVABLES and to take possession of the COLLATERAL and RECORDS relating
thereto. All of the LENDER'S collection expenses shall be charged to the
BORROWER'S account and added to the OBLIGATIONS. If the LENDER is collecting the
RECEIVABLES as above provided, the LENDER shall have the right to receive,
indorse, assign and deliver in the LENDER'S name or the BORROWER'S name any and
all checks, drafts and other instruments for the payment of money relating to
the RECEIVABLES, and the BORROWER hereby waives notice of presentment, protest
and non-payment of any instrument so endorsed. If the LENDER is collecting the
RECEIVABLES directly as above provided, the BORROWER hereby constitutes the
LENDER or the LENDER'S designee as the BORROWER'S attorney-in-fact with power
with respect to the RECEIVABLES: (a) to indorse


<PAGE>




the BORROWER'S name upon all notes, acceptances, checks, drafts, money orders or
other evidences of payment of COLLATERAL that may come into the LENDER'S
possession; (b) to sign the BORROWER'S name on any invoices relating to any of
the RECEIVABLES, drafts against ACCOUNT DEBTORS, assignments and verifications
of RECEIVABLES and notices to ACCOUNT DEBTORS; (c) to send verifications of
RECEIVABLES to any ACCOUNT DEBTOR; (d) to notify the Post Office to change the
address for delivery of mail addressed to the BORROWER to such address as the
LENDER may designate; (e) to receive and open the BORROWER's mail and remove
therefrom all items of payments on RECEIVABLES contained therein (the LENDER
shall use its best efforts to forward to the BORROWER all remaining mail on each
banking day); and (f) to do all other acts and things necessary, proper, or
convenient to carry out the terms and conditions and purposes and intent of this
AGREEMENT. All acts of such attorney or designee are hereby ratified and
approved, and such attorney or designee shall not be liable for any acts of
omission or commission, nor for any error of judgment or mistake of fact or law
in accordance with this AGREEMENT, with the exception of acts arising from
actual fraud or gross and wanton negligence. The power of attorney hereby
granted, being coupled with an interest, is irrevocable while any of the
OBLIGATIONS remain unpaid. The LENDER, without notice to or consent from the
BORROWER, may sue upon or otherwise collect, extend the time of payment of or
compromise or settle for cash, credit or otherwise upon any terms, any of the
RECEIVABLES or any securities, instruments or insurances applicable thereto or
release the obligor thereon. The LENDER is authorized and empowered to accept
the return of the goods represented by any of the RECEIVABLES, without notice to
or consent by the BORROWER, all without discharging or in any way affecting the
BORROWER'S liability under the LOAN DOCUMENTS. The LENDER does not, by anything
herein or in any assignment or otherwise, assume any of the BORROWER'S
obligations under any contract or agreement assigned to the LENDER, and the
LENDER shall not be responsible in any way for the performance by the BORROWER
of any of the terms and conditions thereof.

       Section 4.7. Guaranty Agreements. Each of the GUARANTORS shall execute
and deliver a GUARANTY AGREEMENT to the LENDER which shall guarantee, among
other things, the absolute full payment and performance by the BORROWER of the
OBLIGATIONS. Each of the GUARANTOR'S obligations under the GUARANTY AGREEMENT
executed by such GUARANTOR shall be secured by a security interest in all of
such GUARANTOR'S now owned or hereafter acquired assets, all as more
particularly set forth in the GUARANTY AGREEMENT to be executed by such
GUARANTOR.

       Section 4.8. Further Assurances. The BORROWER will, at its expense,
promptly execute and deliver all further instruments and documents and take all
further action that may be necessary or desirable or that the LENDER may request
from time to time in order: (a) to perfect and protect the security interests
purported to be created hereby; (b) to enable the LENDER to exercise and enforce
its rights and remedies hereunder in respect of the COLLATERAL; or (c) otherwise
to effect the purposes of this AGREEMENT, including, without limitation: (i)
upon the BORROWER'S acquisition thereof, delivering to the LENDER each item of
CHATTEL PAPER of the BORROWER, (ii) if any RECEIVABLES shall be evidenced by a
promissory note or other INSTRUMENT, delivering and pledging to the LENDER such
note or INSTRUMENT duly endorsed and accompanied by executed instruments of
transfer or assignment, all in form and substance satisfactory to the LENDER,
(iii) executing and filing such financing statements or amendments thereto as
may be necessary in order to perfect and


<PAGE>




preserve the security interests purported to be created hereby, (iv) upon the
acquisition after the date hereof by the BORROWER of any EQUIPMENT covered by a
certificate of title or ownership, cause the LENDER to be listed as the
lienholder on such certificate of title and within sixty (60) days of the
acquisition thereof deliver evidence of the same to the LENDER, and (v) upon the
acquisition after the date hereof of any asset for which an assignment, pledge,
mortgage, or other document is required to be filed in order to grant or perfect
a lien therein for the benefit of the LENDER, execute and deliver to the LENDER
such assignment, pledge, mortgage, or other INSTRUMENT within thirty (30) days
of the acquisition thereof. The BORROWER hereby appoints the LENDER or any
officer of the LENDER as the BORROWER'S attorney in fact for purposes of
executing such instruments or documents in the BORROWER'S name, place and stead
following an EVENT OF DEFAULT, which power of attorney shall be considered as
coupled with an interest and irrevocable.

       Section 4.9. Grant Of Security Interest To Leasecorp. As security for all
of the BORROWER'S obligations to LEASECORP under any LEASE in which LEASECORP is
the lessor, the BORROWER hereby assigns to LEASECORP all of the BORROWER'S
right, title, and interest in and to, and grants to LEASECORP a continuing
security interest in and to all of the tangible and intangible assets of the
BORROWER, wherever located, whether now owned or hereafter acquired by the
BORROWER, together with all substitutions therefor, and all replacements and
renewals thereof, and all substitutions, additions, replacement parts, manuals,
warranties and packaging relating thereto including, but not limited to, the
following tangible and intangible assets and property rights of the BORROWER:

                  a. ACCOUNTS;

Dollars ($50,000.00) or deliver assets the value of which exceeds that sum


<PAGE>

material adverse effect upon the financial condition or business operations of
the BORROWER.

       Section 6.7. Payment Of Liabilities To Third Persons. The BORROWER shall

       Section 6.8. Notice Of Change Of Business Location. The BORROWER shall
notify the LENDER thirty (30) days in advance of: (a) any change in the location
of its principal place of business; or (b) any change in or addition to the
locations at which the COLLATERAL is kept unless the new location is in the same
local jurisdiction as the prior location or another existing location of the
BORROWER. At CLOSING the BORROWER shall deliver to the LENDER landlord's
agreements, in form and substance acceptable to the LENDER, executed by: (a)
each landlord of premises located in Baltimore County, Maryland leased by the

GOODS located on each of such premises is greater than the aggregate book value
of the BORROWER'S GOODS located on the other premises (i.e, other than those
premises for which landlord agreements are required) located outside of
Baltimore County, Maryland leased by the BORROWER. In addition, within one
hundred twenty (120) days after the end of each FISCAL YEAR the BORROWER shall
provide the LENDER with such additional Landlord's Agreements (if the LENDER
does not already have one from such landlord), in form and substance acceptable
to the LENDER, that may be necessary in order for the LENDER to have landlord's
agreements for those premises which, as of the end of such FISCAL YEAR,
satisfies one of the criteria set forth in the immediately preceding sentence.

       Section 6.9. Payment Of Taxes. The BORROWER shall pay or cause to be paid
when and as due all taxes, assessments and charges or levies imposed upon it or
on any of its property or which it is required to withhold and pay over to the
taxing authority or which it must pay on its income, except where contested in
good faith, by appropriate proceedings and at its own cost and expense;
provided, however, that the BORROWER shall not be deemed to be contesting in
good faith by appropriate proceedings unless: (a) such proceedings operate to
prevent the taxing authority from attempting to collect the taxes, assessments
or charges; (b) the COLLATERAL is not subject to sale, forfeiture or loss during
such proceedings; (c) the BORROWER'S contest does not subject the LENDER to any
claim by the taxing authority or any other person; (d) the BORROWER establishes
appropriate reserves, satisfactory to the LENDER in its sole discretion, for the
payment of all taxes, assessments, charges, levies, legal fees, court costs and
other expenses for which the BORROWER would be liable if it is unsuccessful in
its contest; (e) the BORROWER prosecutes the contest continuously to its final
conclusion; and (f) at the conclusion of the proceedings, the BORROWER promptly
pays all amounts determined to be payable, including but not limited to all
taxes, assessments, charges, levies, legal fees and court costs.

verify, check and make extracts or photocopies from, the RECORDS of the BORROWER
and other data relating to the COLLATERAL or any of the BORROWER'S LIABILITIES,
and the BORROWER shall reimburse the LENDER for the entire cost of all of such
audits, inspections, verifications, copying, and extractions, provided that the
maximum aggregate amount of such costs for which the BORROWER shall be obligated
to reimburse the LENDER for in any calendar year is Seven Thousand Five Hundred
Dollars ($7,500.00) unless there is an EVENT OF DEFAULT in which case there is
no such limitation.

       Section 6.11. Collection Of Receivables By Borrower. Unless the

LENDER, as provided in this AGREEMENT, the BORROWER, at the BORROWER'S sole
expense, shall collect, when and as due, all sums due on the RECEIVABLES. The
BORROWER shall take such action in collecting the RECEIVABLES as the LENDER may
request, or in the absence of such request, as the BORROWER may deem advisable.

       Section 6.12. Notice Of Events Affecting Collateral; Compromise Of
Receivables. The BORROWER, immediately upon learning thereof, shall report to
the LENDER: (a) all claims or disputes asserted by any ACCOUNT DEBTOR or other
obligor involving in excess of Fifty Thousand Dollars ($50,000.00); and (b) all
matters materially affecting the value, enforceability or collectibility of any
of the COLLATERAL. The BORROWER shall immediately notify the LENDER in the event
the aggregate amount of adjustments and compromises of those RECEIVABLES which
were reported to the LENDER as an ELIGIBLE ACCOUNT on the most recent collateral

the most recent collateral and loan report delivered to the LENDER.

       Section 6.13. Documentation Of Collateral. The BORROWER, upon request of
the LENDER, shall provide the LENDER from time to time with: (a) written
statements or schedules identifying and describing the COLLATERAL, and all
additions, substitutions, and replacements thereof, in such detail as the LENDER
may require; (b) copies of ACCOUNT DEBTORS' invoices or billing statements; (c)
evidence of shipment or delivery of goods or merchandise to or performance of
services for ACCOUNT DEBTORS; and (d) such other schedules and information as
the LENDER reasonably may require. The items to be provided under this Section
shall be in form satisfactory to the LENDER and are to be executed and delivered
to the LENDER from time to time solely for the LENDER'S convenience in
maintaining RECORDS of the COLLATERAL. The BORROWER'S failure to give any of
such items to the LENDER shall not affect, terminate, modify or otherwise limit
the LENDER'S security interest in the COLLATERAL. The LENDER shall have the
right, at any time and from time to time, to verify the eligibility of the
BORROWER'S RECEIVABLES, including obtaining verification of the RECEIVABLES
directly from ACCOUNT DEBTORS.

       Section 6.14. Reporting Requirements.  The BORROWER shall submit the

herein, upon the occurrence of an EVENT OF DEFAULT, the LENDER, in a
commercially reasonable fashion, may sell at public or private sale or otherwise
realize upon, in Baltimore, Maryland, or elsewhere, the whole or, from time to
time, any part of all COLLATERAL which is personal property, or any interest
which the BORROWER may have therein. Pending any such action, the LENDER may
collect and liquidate such COLLATERAL. After deducting from the proceeds of sale
or other disposition of such COLLATERAL all expenses, including all expenses for
legal services, the LENDER shall apply such proceeds toward the satisfaction of
the OBLIGATIONS. Any remainder of the proceeds after satisfaction in full of the
OBLIGATIONS shall be distributed as required by applicable LAW. Notice of any
sale or other disposition shall be given to the BORROWER at least ten (10) days
before the time of any intended public sale or of the time after which any
intended private sale or other disposition of the COLLATERAL is to be made,
which the BORROWER hereby agrees shall be commercially reasonable notice of such
sale or other disposition. The BORROWER shall assemble, or shall cause to be
assembled, at the BORROWER'S own expense, the COLLATERAL at such place or places
as the LENDER shall designate. At any such sale or other disposition, the LENDER
may, to the extent permissible under applicable law, purchase the whole or any
part of the COLLATERAL, free from any right of redemption on the part of the
BORROWER, which right is hereby waived and released to the extent lawfully
permitted. Without limiting the generality of any of the rights and remedies
conferred upon the LENDER under this Section, the LENDER may, to the full extent
permitted by applicable law: (a) enter upon the premises of the BORROWER, and
take immediate possession of the COLLATERAL, either personally or by means of a
receiver appointed by a court of competent jurisdiction, using all necessary


<PAGE>




force to do so; (b) at the LENDER'S option, use, operate, manage, and control
the COLLATERAL in any lawful manner; (c) collect and receive all income,
revenue, earnings, issues, and profits therefrom; and (d) maintain, alter or
remove the COLLATERAL as the LENDER may determine in the LENDER'S discretion.

       Section 9.4. Remedies Cumulative. The rights and remedies provided in
this AGREEMENT and in the other LOAN DOCUMENTS or otherwise under applicable
LAWS shall be cumulative and the exercise of any particular right or remedy
shall not preclude the exercise of any other rights or remedies in addition to,
or as an alternative of, such right or remedy.

                          GENERAL CONDITIONS AND TERMS
                          ----------------------------

       Section 10.1. Obligations Are Unconditional. The payment and performance
of the OBLIGATIONS shall be the absolute and unconditional duty and obligation
of the BORROWER, and shall be independent of any defense or any rights of
set-off, recoupment or counterclaim which the BORROWER might otherwise have
against the LENDER, and the BORROWER shall pay absolutely during the terms of
the LOANS the payments of the principal and interest to be made on account of
the LOANS and all other payments required hereunder, free of any deductions and
without abatement, diminution or set-off other than those herein expressly
provided. Until such time as the OBLIGATIONS have been fully paid and performed,
the BORROWER: (a) shall not suspend or discontinue any payments provided for
herein and in the NOTES; (b) shall perform and observe all of the BORROWER'S
other covenants and agreements contained in the LOAN DOCUMENTS, including but
not limited to making all payments required to be made to the LENDER; and (c)
shall not terminate or attempt to terminate the LOAN DOCUMENTS for any cause.

       Section 10.2. Indemnity. The BORROWER agrees to defend, indemnify and
hold harmless the LENDER and the LENDER'S parents, subsidiaries, affiliates,
employees, agents, officers and directors, from and against any losses,
penalties, fines, liabilities, settlements, damages, costs and expenses,
suffered in connection with any claim, investigation, litigation or other
proceeding (whether or not the LENDER is a party thereof) and the prosecution
and defense thereof, arising out of or in any way connected with this AGREEMENT,
any other LOAN DOCUMENT or the LOANS, including without limitation reasonable
attorneys' and consultant's fees, except to the extent that any of the foregoing
directly result from the gross negligence or willful misconduct of the party
seeking indemnification therefor. Notwithstanding any termination of this
AGREEMENT or payment and performance of the OBLIGATIONS, the indemnities
provided for herein shall continue in full force and effect and shall protect
the LENDER against events arising after such termination, payment or performance
as well as before.

       Section 10.3. Lender Expenses.  All LENDER EXPENSES shall be paid by the
BORROWER, whether incurred prior to or after CLOSING, so that the subject
transactions shall at all times be cost free to the LENDER.

       Section 10.4. Authorization To Obtain Financial Information. The BORROWER
hereby irrevocably authorizes its accounting firm to provide the LENDER from
time to time with such information as may be requested by the


<PAGE>




LENDER, and hereby authorizes the LENDER to contact directly any such accounting
firm in order to obtain such information.

       Section 10.5. Incorporation; Construction Of Inconsistent Provisions. The
terms and conditions of the LOAN DOCUMENTS are incorporated by reference and
made a part hereof, as if fully set forth herein. In the event of any
inconsistency between this AGREEMENT and any other LOAN DOCUMENT, such
inconsistency shall be construed, interpreted, and resolved so as to benefit the
LENDER, independent of whether this AGREEMENT or another LOAN DOCUMENT controls,
and the LENDER'S election of which interpretation or construction is for the
LENDER'S benefit shall govern.

       Section 10.6. Waivers. The LENDER at any time or from time to time may
waive all or any rights under this AGREEMENT or any other LOAN DOCUMENT, but any
waiver or indulgence by the LENDER at any time or from time to time shall not
constitute a future waiver of performance or exact performance by the BORROWER.

       Section 10.7. Continuing Obligation Of Borrower. The terms, conditions,
and covenants set forth herein and in the LOAN DOCUMENTS shall survive CLOSING
and shall constitute a continuing obligation of the BORROWER during the course
of the transactions contemplated herein. The OBLIGATIONS of the BORROWER under
this AGREEMENT shall remain in effect so long as any OBLIGATION is outstanding,
unpaid or unsatisfied between the BORROWER and the LENDER.

       Section 10.8. Choice Of Law. The laws of the State of Maryland
(excluding, however, conflict of law principles) shall govern and be applied to
determine all issues relating to this AGREEMENT and the rights and obligations
of the parties hereto, including the validity, construction, interpretation, and
enforceability of this AGREEMENT and its various provisions and the consequences
and legal effect of all transactions and events which resulted in the execution
of this AGREEMENT or which occurred or were to occur as a direct or indirect
result of this AGREEMENT having been executed.

       Section 10.9. Submission/ To Jurisdiction; Venue; Actions Against Lender.
For purposes of any action, in law or in equity, which is based directly or
indirectly on this AGREEMENT, any other LOAN DOCUMENT or any matter related to
this AGREEMENT or any other LOAN DOCUMENT, including any action for recognition
or enforcement of any of the LENDER'S rights under the LOAN DOCUMENTS or any
judgment obtained by the LENDER in respect thereof, the BORROWER hereby:

                  a. Irrevocably submits to the non-exclusive general
jurisdiction of the courts of the State of Maryland and, if a basis for federal
jurisdiction exists at any time, the courts of the United States of America for
the District of Maryland;

                  b. Agrees that venue shall be proper in the Circuit Court for
Baltimore City, Maryland, the Circuit Court for any county in the state of
Maryland, as selected by the LENDER, and, if a basis for federal jurisdiction
exists, the courts of the United States of America for the District of Maryland;
and


<PAGE>




                  c. Waives any right to object to the maintenance of any suit
in any of the courts specified in clause (b) above on the basis of improper
venue or convenience of forum.

                  The BORROWER further agrees that it shall not institute any
suit or other action against the LENDER, in law or in equity, which is based
directly or indirectly on this AGREEMENT, any other LOAN DOCUMENT or any matter
related to this AGREEMENT or any other LOAN DOCUMENT, in any court other than a
court specified in clause (b) above; provided, that in any instance in which
there is then pending a suit instituted by the LENDER against the BORROWER in a
court other than a court specified in clause (b) above, the BORROWER may file in
such suit any counterclaim which it has against the LENDER but only if such
counterclaim is a compulsory counterclaim and would be barred if not filed as a
counterclaim in such suit. The BORROWER agrees that any suit brought by it
against the LENDER not in accordance with this paragraph should be forthwith
dismissed or transferred to a court specified in clause (b) above.

       Section 10.10. Notices. Any notice required or permitted by or in
connection with this AGREEMENT shall be in writing and shall be made by
facsimile (confirmed on the date the facsimile is sent by one of the other
methods of giving notice provided for in this Section) or by hand delivery, by
Federal Express, or other similar overnight delivery service, or by certified
mail, unrestricted delivery, return receipt requested, postage prepaid,

whether delivery is ever in fact made, as the case may be, provided the giver of
notice can establish the fact that notice was given as provided herein. If

the intended recipient thereof, the notice, nevertheless, shall be considered to
have been given and shall be effective as of the date herein provided.

                         REVOLVING LOAN PROMISSORY NOTE
                         ------------------------------

         FOR VALUE RECEIVED, the undersigned EA ENGINEERING, SCIENCE, AND
TECHNOLOGY, INC., a Delaware corporation ("BORROWER"), promises to pay to the
order of THE FIRST NATIONAL BANK OF MARYLAND, a national banking association
("LENDER"), at the LENDER'S offices at 25 South Charles Street, Baltimore,
Maryland 21201 or at such other places as the holder of this Promissory Note may
from time to time designate, the principal sum of Eight Million Five Hundred
Thousand Dollars ($8,500,000.00), or so much as may have been advanced to the
BORROWER under the terms of the "REVOLVING LOAN," as defined and described in
the Loan And Security Agreement of even date herewith between the LENDER and the
BORROWER ("AGREEMENT"), together with interest thereon at the rate or rates
hereafter specified until paid in full and any and all other sums which may be
owing to the holder of this Promissory Note by the BORROWER pursuant to this
Promissory Note. The following terms shall apply to this Promissory Note.

         11. Interest Rate. Interest shall accrue on the unpaid principal
balance of this Promissory Note until paid in full at the fluctuating annual
rate of interest set forth in the AGREEMENT.

         12. Calculation Of Interest. Interest shall be calculated on the basis
of a three hundred sixty (360) days per year factor applied to the actual days
on which there exists an unpaid balance hereunder.

         13. Repayment. Accrued and unpaid interest, plus any then due
applicable late payment charges or default interest, shall be paid in
consecutive monthly payments beginning on September 1, 1997 and continuing on
the first calendar day of each succeeding month until September 30, 1999, which
is the final and absolute maturity date of this Promissory Note, at which time
all sums due hereunder that remain unpaid, including principal, interest,
charges and fees, shall be paid in full.

         14. Late Payment Charge. If any payment due hereunder, including any
final installment, is not received by the holder within fifteen (15) calendar
days after its due date, the BORROWER shall pay a late payment charge equal to
five percent (5%) of the amount then due. The late payment charge shall be due
whether or not the holder declares this Promissory Note in default or
accelerates and demands immediate payment of the sums due hereunder. The
existence of the right by the holder to receive a late payment charge shall not
constitute a grace period or provide any right in the BORROWER to make a payment
other than on its due date.

         15. Application Of Payments. All payments made hereunder shall be
applied first to late payment charges or other sums owed to the holder, next to
accrued interest, and then to principal, or in such other order or proportion as
the holder, in the holder's sole discretion, may elect from time to time.

         16. Prepayment. The BORROWER may prepay this Promissory Note in whole
or in part at any time or from time to time without premium or additional


<PAGE>




interest. All prepayments under this Promissory Note shall be applied to the
outstanding principal balance in the inverse order of scheduled maturities.

         17. Rights Upon Default. Upon the occurrence of an "EVENT OF DEFAULT"
(as that term is defined in the AGREEMENT), in addition to all other rights or
remedies available to the holder under the AGREEMENT and all other documents
evidencing, securing or otherwise documenting the loan evidenced by this
Promissory Note (collectively with the AGREEMENT, the "LOAN DOCUMENTS") or under
applicable law, the holder of this Promissory Note shall have the following
rights:

                  17.1. Acceleration. The holder of this Promissory Note, in the
holder's sole discretion and without notice or demand, may declare the entire
unpaid principal balance plus accrued interest and all other sums due hereunder
immediately due and payable. Reference is made to the LOAN DOCUMENTS for further
and additional rights on the part of the holder to declare the entire unpaid
principal balance plus accrued interest and all other sums due hereunder
immediately due and payable.

                  17.2. Default Interest Rate. The holder of this Promissory
Note, in the holder's sole discretion and without notice or demand, may raise
the rate of interest accruing on the unpaid principal balance by two (2)
percentage points above the rate of interest otherwise applicable, independent
of whether the holder elects to accelerate the unpaid principal balance as a
result of such default, unless prior to the imposition of the default rate of
interest, the BORROWER cures such event to the satisfaction of the holder
hereof. If the default rate of interest is imposed by the holder, the default
rate shall remain in effect until the event authorizing the imposition thereof
has been cured to the holder's satisfaction. Any individual waiver of the
holder's right to impose the default rate of interest or to retain the default
rate of interest after imposition thereof shall not be considered a waiver of
this section or any future right of the holder to impose the default rate of
interest pursuant to this Section.

                  17.3. Confession Of Judgment. The BORROWER authorizes any
attorney admitted to practice before any court of record in the United States to
appear on behalf of the BORROWER in any court in one or more proceedings, or
before any clerk thereof or prothonotary or other court official, and to confess
judgment against the BORROWER in favor of the holder of this Promissory Note in
the full amount due on this Promissory Note (including principal, accrued
interest and any and all charges, fees and costs) plus attorneys' fees equal to
fifteen percent (15%) of the amount due, plus court costs, all without prior
notice or opportunity of the BORROWER for prior hearing. The BORROWER agrees and
consents that venue and jurisdiction shall be proper in the Circuit Court of any
County of the State of Maryland or of Baltimore City, Maryland, or in the United
States District Court for the District of Maryland. The BORROWER waives the
benefit of any and every statute, ordinance, or rule of court which may be
lawfully waived conferring upon the BORROWER any right or privilege of
exemption, homestead rights, stay of execution, or supplementary proceedings, or
other relief from the enforcement or immediate enforcement of a judgment or
related proceedings on a judgment; provided, however, the BORROWER does not
waive the right to raise a defense based on an actual controversy as to the
merits of the confession of judgment action under Rule 2-611, Maryland Rules,
Annotated Code of Maryland. The authority and power to appear for and enter
judgment against the BORROWER shall


<PAGE>




not be exhausted by one or more exercises thereof, or by any imperfect exercise
thereof, and shall not be extinguished by any judgment entered pursuant thereto;
such authority and power may be exercised on one or more occasions from time to
time, in the same or different jurisdictions, as often as the holder shall deem
necessary, convenient, or proper. Notwithstanding the holder's right to obtain a
judgment by confession which includes attorney's fees of fifteen percent of the
amount due hereunder, the holder shall only collect attorney fees in an amount
equal to the actual attorney fees incurred in connection with the enforcement of
this Promissory Note and the LOAN DOCUMENTS.

         18. Interest Rate After Judgment. If judgment is entered against the
BORROWER on this Promissory Note, the amount of the judgment entered (which may
include principal, interest, fees, and costs) shall bear interest at the higher
of the maximum interest rate imposed upon judgments by applicable law or the
above described default interest rate, to be determined on the date of the entry
of the judgment.

         19. Expenses Of Collection And Attorneys' Fees. Should this Promissory
Note be referred to an attorney for collection, whether or not judgment has been
confessed or suit has been filed, the BORROWER shall pay all of the holder's
reasonable costs, fees and expenses, including reasonable attorneys' fees,
resulting from such referral.

         20. Waiver Of Defenses. In the event any one or more holders of this
Promissory Note transfer this Promissory Note for value, the BORROWER agrees
that all subsequent holders of this Promissory Note who take for value and
without actual knowledge of a claim or defense of the BORROWER against a prior
holder shall not be subject to any claims or defenses which the BORROWER may
have against a prior holder, all of which are waived as to the subsequent
holder, and that all such subsequent holders shall have all rights of a holder
in due course with respect to the BORROWER even though the subsequent holder may
not qualify, under applicable law, absent this section, as a holder in due
course. The BORROWER shall retain all rights and claims which the BORROWER may
have against prior holders despite any such transfers and the waiver of defenses
provided in this section as to subsequent holders.

         21. Waiver Of Protest. The BORROWER, and all parties to this Promissory
Note, whether maker, indorser, or guarantor, waive presentment, notice of
dishonor and protest.

         22. Extensions Of Maturity. All parties to this Promissory Note,
whether maker, indorser, or guarantor, agree that the maturity of this
Promissory Note, or any payment due hereunder, may be extended at any time or
from time to time without releasing, discharging, or affecting the liability of
such party.

         23. Manner And Method Of Payment. All payments called for in this
Promissory Note shall be made in lawful money of the United States of America.
If made by check, draft, or other payment instrument, such check, draft, or
other payment instrument shall represent immediately available funds. In the
holder's discretion, any payment made by a check, draft, or other payment
instrument shall not be considered to have been made until such time as the
funds represented thereby have been collected by the holder. Should any payment
date fall on a non-banking day, the BORROWER shall make the payment on the next
succeeding banking day.


<PAGE>




         24. Notices. Any notice or demand required or permitted by or in
connection with this Promissory Note shall be given in the manner specified in
the AGREEMENT for the giving of notices under the AGREEMENT. Notwithstanding
anything to the contrary, all notices and demands for payment from the holder
actually received in writing by the BORROWER shall be considered to be effective
upon the receipt thereof by the BORROWER regardless of the procedure or method
utilized to accomplish delivery thereof to the BORROWER.

         25. Assignability. This Promissory Note may be assigned by the LENDER
or any holder at any time or from time to time.

         26. Joint And Several Liability. If more than one person or entity is
executing this Promissory Note as a BORROWER, all liabilities under this
Promissory Note shall be joint and several with respect to each of such persons
or entities.

         27. Binding Nature. This Promissory Note shall inure to the benefit of
and be enforceable by the LENDER and the LENDER'S successors and assigns and any
other person to whom the LENDER or any holder may grant an interest in the
BORROWER'S obligations hereunder, and shall be binding and enforceable against
the BORROWER and the BORROWER'S personal representatives, successors and
assigns.

         28. Invalidity Of Any Part. If any provision or part of any provision
of this Promissory Note shall for any reason be held invalid, illegal or
unenforceable in any respect, such invalidity, illegality or unenforceability
shall not affect any other provisions of this Promissory Note and this
Promissory Note shall be construed as if such invalid, illegal or unenforceable
provision or part thereof had never been contained herein, but only to the
extent of its invalidity, illegality, or unenforceability.

         29. Choice Of Law. The laws of the State of Maryland (excluding,
however, conflict of law principles) shall govern and be applied to determine
all issues relating to this Promissory Note and the rights and obligations of
the parties hereto, including the validity, construction, interpretation, and
enforceability of this Promissory Note and its various provisions and the
consequences and legal effect of all transactions and events which resulted in
the issuance of this Promissory Note or which occurred or were to occur as a
direct or indirect result of this Promissory Note having been executed.

         30. Consent To Jurisdiction; Agreement As To Venue. The BORROWER
irrevocably consents to the non-exclusive jurisdiction of the courts of the
State of Maryland and of the United States District Court for the District of
Maryland, if a basis for federal jurisdiction exists. The BORROWER agrees that
venue shall be proper in any circuit court of the State of Maryland selected by
the LENDER or in the United States District Court for the District of Maryland
if a basis for federal jurisdiction exists and waives any right to object to the
maintenance of a suit in any of the state or federal courts of the State of
Maryland on the basis of improper venue or of inconvenience of forum.

         31. Unconditional Obligations. The BORROWER'S obligations under this
Promissory Note shall be the absolute and unconditional duty and obligation of
the BORROWER and shall be independent of any rights of set-off, recoupment or
counterclaim which the BORROWER might otherwise have against the holder of this
Promissory Note, and the BORROWER shall pay absolutely the payments of
principal,


<PAGE>




interest, fees and expenses required hereunder, free of any deductions and
without abatement, diminution or set-off.

         32. Seal And Effective Date. This Promissory Note is an instrument
executed under seal and is to be considered effective and enforceable as of the
date set forth on the first page hereof, independent of the date of actual
execution and delivery.

         33. Tense; Gender; Defined Terms; Section Headings. As used herein, the
singular includes the plural and the plural includes the singular. A reference
to any gender also applies to any other gender. Defined terms are entirely
capitalized throughout. The section headings are for convenience only and are
not part of this Promissory Note.

         34. Actions Against Lender. Any action brought by the BORROWER against
the LENDER which is based, directly or indirectly, on this Promissory Note or
any matter in or related to this Promissory Note, including but not limited to
the making of the loan evidenced hereby or the administration or collection
thereof, shall be brought only in courts located in the State of Maryland. The
BORROWER may not file a counterclaim against the LENDER in a suit brought by the
LENDER against the BORROWER in a state other than the State of Maryland unless
under the rules of procedure of the court in which the LENDER brought the action
the counterclaim is mandatory, and not merely permissive, and will be considered
waived unless filed as a counterclaim in the action instituted by the LENDER.
The BORROWER agrees that any forum other than the State of Maryland is an
inconvenient forum and that a suit brought by the BORROWER against the LENDER in
a court of any state other than the State of Maryland should be forthwith
dismissed or transferred to a court located in the State of Maryland by that
Court.

         35. Waiver Of Jury Trial. The BORROWER (by execution of this Promissory
Note) and the LENDER (by acceptance of this Promissory Note) agree that any
suit, action, or proceeding, whether claim or counterclaim, brought or
instituted by or against the BORROWER or the LENDER, or any successor or assign
of the BORROWER or the LENDER, on or with respect to this Promissory Note or any
of the other LOAN DOCUMENTS, or which in any way relates, directly or
indirectly, to the obligations of the BORROWER to the LENDER under this
Promissory Note or any of the other LOAN DOCUMENTS, or the dealings of the
parties with respect thereto, shall be tried only by a court and not by a jury.
THE BORROWER AND THE LENDER HEREBY EXPRESSLY WAIVE ANY RIGHT TO A TRIAL BY JURY
IN ANY SUCH SUIT, ACTION, OR PROCEEDING. The BORROWER and the LENDER acknowledge
and agree that this provision is a specific and material aspect of the agreement
between the parties and that the LENDER would not enter into the transaction
with the BORROWER if this provision were not part of their agreement.

August 22, 1997

                            TERM LOAN PROMISSORY NOTE
                            -------------------------

         FOR VALUE RECEIVED, the undersigned EA ENGINEERING, SCIENCE, AND
TECHNOLOGY, INC., a Delaware corporation ("BORROWER"), promises to pay to the
order of THE FIRST NATIONAL BANK OF MARYLAND, a national banking association
("LENDER"), at the LENDER'S offices at 25 South Charles Street, Baltimore,
Maryland 21201 or at such other places as the holder of this Promissory Note may
from time to time designate, the principal sum of Four Hundred Thirty-One
Thousand Seven Hundred Forty-Six Dollars and Twenty-Eight Cents ($431,746.28),
together with interest thereon at the rate or rates hereafter specified until
paid in full and any and all other sums which may be owing to the holder of this
Promissory Note by the BORROWER pursuant to this Promissory Note. The following
terms shall apply to this Promissory Note.

         36. Interest Rate. Interest shall accrue on the unpaid principal
balance of this Promissory Note until paid in full at an annual rate of interest
as set forth in the Loan And Security Agreement of even date herewith by and
between the BORROWER and the LENDER ("AGREEMENT").

         37. Calculation Of Interest. Interest shall be calculated on the basis
of a three hundred sixty (360) days per year factor applied to the actual days
on which there exists an unpaid balance hereunder.

         38. Repayment. Payments of accrued and unpaid interest only shall be
made by the BORROWER to the holder of this Promissory Note on September 1, 1997,
and on the first calendar day of each month thereafter until all sums
outstanding hereunder are paid in full. The principal balance of this Promissory
Note shall be repaid as follows: (a) On August 21, 1997, September 21, 1997,
October 21, 1997 and November 21, 1997, the BORROWER shall make monthly
principal payments in the amount of Forty-three Thousand, Six Hundred Fifty
Dollars and Seventy-nine Cents ($43,650.79); (b) commencing on December 21,
1997, and continuing on the Twenty-first day of each month thereafter until all
principal sums outstanding hereunder are paid in full, the Borrower shall make
monthly payments of Twenty- one Thousand Four Hundred Twenty-Eight Dollars and
Fifty-seven Cents ($21,428.57); and (c) on October 21, 1998, which date is the
final and absolute maturity date of this Promissory Note, the Borrower shall
make payment of all sums due hereunder, including principal, interest, charges
and fees, shall be paid in full.

         39. Late Payment Charge. If any payment due hereunder, including any
final installment, is not received by the holder within fifteen (15) calendar
days after its due date, the BORROWER shall pay a late payment charge equal to
five percent (5%) of the amount then due. The late payment charge shall be due
whether or not the holder declares this Promissory Note in default or
accelerates and demands immediate payment of the sums due hereunder. The
existence of the right by the holder to receive a late payment charge shall not
constitute a grace period or provide any right in the BORROWER to make a payment
other than on its due date.


<PAGE>




         40. Application Of Payments. All payments made hereunder shall be
applied first to late payment charges or other sums owed to the holder, next to
accrued interest, and then to principal, or in such other order or proportion as
the holder, in the holder's sole discretion, may elect from time to time.

         41. Prepayment. If interest is accruing on the unpaid principal balance
of this Promissory Note at a fluctuating rate of interest, the BORROWER may
prepay this Promissory Note in whole or in part at any time or from time to time
without premium or additional interest. If interest is accruing on the unpaid
principal balance of this Promissory Note at a fixed rate of interest, the
BORROWER shall pay a prepayment fee to the holder of this Promissory Note in the
event all or any portion of the principal balance of this Promissory Note is
paid prior to its original scheduled maturity date. The prepayment fee shall be
calculated by discounting to present value, as of the date of prepayment, the
remaining payments of principal and interest on the principal balance of the
Promissory Note being prepaid, using a discount rate equal to one percent (1%)
above the yield to maturity of the noncallable debt obligation of the United
States Treasury having a maturity date nearest in time to the maturity date of
the portion of the principal outstanding under this Promissory Note being
prepaid. If such a discounted value exceeds the unpaid principal amount being
prepaid, then the prepayment fee shall be in an amount equal to such excess. If
the discounted value does not exceed the unpaid principal amount being prepaid,
there shall be no prepayment fee. The maturity date and yield to maturity of the
applicable United States Treasury obligation shall be determined on the basis of
quotations published in the Wall Street Journal on the date of prepayment or
from such other source as the holder of this Promissory Note, in its sole
discretion shall deem appropriate. All prepayments under this Promissory Note
shall be applied to the outstanding principal balance in the inverse order of
scheduled maturities.

         42. Rights Upon Default. Upon the occurrence of an "EVENT OF DEFAULT"
(as that term is defined in the AGREEMENT), in addition to all other rights or
remedies available to the holder under the AGREEMENT and all other documents
evidencing, securing or otherwise documenting the loan evidenced by this
Promissory Note (collectively with the AGREEMENT, the "LOAN DOCUMENTS") or under
applicable law, the holder of this Promissory Note shall have the following
rights:

                  42.1. Acceleration. The holder of this Promissory Note, in the
holder's sole discretion and without notice or demand, may declare the entire
unpaid principal balance plus accrued interest and all other sums due hereunder
immediately due and payable. Reference is made to the LOAN DOCUMENTS for further
and additional rights on the part of the holder to declare the entire unpaid
principal balance plus accrued interest and all other sums due hereunder
immediately due and payable.

                  42.2. Default Interest Rate. The holder of this Promissory
Note, in the holder's sole discretion and without notice or demand, may raise
the rate of interest accruing on the unpaid principal balance by two (2)
percentage points above the rate of interest otherwise applicable, independent
of whether the holder elects to accelerate the unpaid principal balance as a
result of such default, unless prior to the imposition of the default rate of
interest, the BORROWER cures such event to the satisfaction of the holder
hereof. If the default rate of interest is imposed by the holder, the default
rate shall remain


<PAGE>




in effect until the event authorizing the imposition thereof has been cured to
the holder's satisfaction. Any individual waiver of the holder's right to impose
the default rate of interest or to retain the default rate of interest after
imposition thereof shall not be considered a waiver of this section or any
future right of the holder to impose the default rate of interest pursuant to
this Section.

                  42.3. Confession Of Judgment. The BORROWER authorizes any
attorney admitted to practice before any court of record in the United States to
appear on behalf of the BORROWER in any court in one or more proceedings, or
before any clerk thereof or prothonotary or other court official, and to confess
judgment against the BORROWER in favor of the holder of this Promissory Note in
the full amount due on this Promissory Note (including principal, accrued
interest and any and all charges, fees and costs) plus attorneys' fees equal to
fifteen percent (15%) of the amount due, plus court costs, all without prior
notice or opportunity of the BORROWER for prior hearing. The BORROWER agrees and
consents that venue and jurisdiction shall be proper in the Circuit Court of any
County of the State of Maryland or of Baltimore City, Maryland, or in the United
States District Court for the District of Maryland. The BORROWER waives the
benefit of any and every statute, ordinance, or rule of court which may be
lawfully waived conferring upon the BORROWER any right or privilege of
exemption, homestead rights, stay of execution, or supplementary proceedings, or
other relief from the enforcement or immediate enforcement of a judgment or
related proceedings on a judgment; provided, however, the BORROWER does not
waive the right to raise a defense based on an actual controversy as to the
merits of the confession of judgment action under Rule 2-611, Maryland Rules,
Annotated Code of Maryland. The authority and power to appear for and enter
judgment against the BORROWER shall not be exhausted by one or more exercises
thereof, or by any imperfect exercise thereof, and shall not be extinguished by
any judgment entered pursuant thereto; such authority and power may be exercised
on one or more occasions from time to time, in the same or different
jurisdictions, as often as the holder shall deem necessary, convenient, or
proper. Notwithstanding the holder's right to obtain a judgment by confession
which includes attorney's fees of fifteen percent of the amount due hereunder,
the holder shall only collect attorney fees in an amount equal to the actual
attorney fees incurred in connection with the enforcement of this Promissory
Note and the LOAN DOCUMENTS.

         43. Interest Rate After Judgment. If judgment is entered against the
BORROWER on this Promissory Note, the amount of the judgment entered (which may
include principal, interest, fees, and costs) shall bear interest at the higher
of the maximum interest rate imposed upon judgments by applicable law or the
above described default interest rate, to be determined on the date of the entry
of the judgment.

         44. Expenses Of Collection And Attorneys' Fees. Should this Promissory
Note be referred to an attorney for collection, whether or not judgment has been
confessed or suit has been filed, the BORROWER shall pay all of the holder's
reasonable costs, fees and expenses, including reasonable attorneys' fees,
resulting from such referral.

         45. Waiver Of Defenses. In the event any one or more holders of this
Promissory Note transfer this Promissory Note for value, the BORROWER agrees
that all subsequent holders of this Promissory Note who take for value and
without actual knowledge of a claim or defense of the BORROWER against a prior
holder


<PAGE>




shall not be subject to any claims or defenses which the BORROWER may have
against a prior holder, all of which are waived as to the subsequent holder, and
that all such subsequent holders shall have all rights of a holder in due course
with respect to the BORROWER even though the subsequent holder may not qualify,
under applicable law, absent this section, as a holder in due course. The
BORROWER shall retain all rights and claims which the BORROWER may have against
prior holders despite any such transfers and the waiver of defenses provided in
this section as to subsequent holders.

         46. Waiver Of Protest. The BORROWER, and all parties to this Promissory
Note, whether maker, indorser, or guarantor, waive presentment, notice of
dishonor and protest.

         47. Extensions Of Maturity. All parties to this Promissory Note,
whether maker, indorser, or guarantor, agree that the maturity of this
Promissory Note, or any payment due hereunder, may be extended at any time or
from time to time without releasing, discharging, or affecting the liability of
such party.

         48. Manner And Method Of Payment. All payments called for in this
Promissory Note shall be made in lawful money of the United States of America.
If made by check, draft, or other payment instrument, such check, draft, or
other payment instrument shall represent immediately available funds. In the
holder's discretion, any payment made by a check, draft, or other payment
instrument shall not be considered to have been made until such time as the
funds represented thereby have been collected by the holder. Should any payment
date fall on a non-banking day, the BORROWER shall make the payment on the next
succeeding banking day.

         49. Notices. Any notice or demand required or permitted by or in
connection with this Promissory Note shall be given in the manner specified in
the AGREEMENT for the giving of notices under the AGREEMENT. Notwithstanding
anything to the contrary, all notices and demands for payment from the holder
actually received in writing by the BORROWER shall be considered to be effective
upon the receipt thereof by the BORROWER regardless of the procedure or method
utilized to accomplish delivery thereof to the BORROWER.

         50. Assignability. This Promissory Note may be assigned by the LENDER
or any holder at any time or from time to time.

         51. Joint And Several Liability. If more than one person or entity is
executing this Promissory Note as a BORROWER, all liabilities under this
Promissory Note shall be joint and several with respect to each of such persons
or entities.

         52. Binding Nature. This Promissory Note shall inure to the benefit of
and be enforceable by the LENDER and the LENDER'S successors and assigns and any
other person to whom the LENDER or any holder may grant an interest in the
BORROWER'S obligations hereunder, and shall be binding and enforceable against
the BORROWER and the BORROWER'S personal representatives, successors and
assigns.

         53. Invalidity Of Any Part. If any provision or part of any provision
of this Promissory Note shall for any reason be held invalid, illegal or
unenforceable in any respect, such invalidity, illegality or unenforceability
shall not affect any other provisions of this Promissory Note and this
Promissory


<PAGE>




Note shall be construed as if such invalid, illegal or unenforceable provision
or part thereof had never been contained herein, but only to the extent of its
invalidity, illegality, or unenforceability.

         54. Choice Of Law. The laws of the State of Maryland (excluding,
however, conflict of law principles) shall govern and be applied to determine
all issues relating to this Promissory Note and the rights and obligations of
the parties hereto, including the validity, construction, interpretation, and
enforceability of this Promissory Note and its various provisions and the
consequences and legal effect of all transactions and events which resulted in
the issuance of this Promissory Note or which occurred or were to occur as a
direct or indirect result of this Promissory Note having been executed.

         55. Consent To Jurisdiction; Agreement As To Venue. The BORROWER
irrevocably consents to the non-exclusive jurisdiction of the courts of the
State of Maryland and of the United States District Court for the District of
Maryland, if a basis for federal jurisdiction exists. The BORROWER agrees that
venue shall be proper in any circuit court of the State of Maryland selected by
the LENDER or in the United States District Court for the District of Maryland
if a basis for federal jurisdiction exists and waives any right to object to the
maintenance of a suit in any of the state or federal courts of the State of
Maryland on the basis of improper venue or of inconvenience of forum.

         56. Unconditional Obligations. The BORROWER'S obligations under this
Promissory Note shall be the absolute and unconditional duty and obligation of
the BORROWER and shall be independent of any rights of set-off, recoupment or
counterclaim which the BORROWER might otherwise have against the holder of this
Promissory Note, and the BORROWER shall pay absolutely the payments of
principal, interest, fees and expenses required hereunder, free of any
deductions and without abatement, diminution or set-off.

         57. Seal And Effective Date. This Promissory Note is an instrument
executed under seal and is to be considered effective and enforceable as of the
date set forth on the first page hereof, independent of the date of actual
execution and delivery.

         58. Tense; Gender; Defined Terms; Section Headings. As used herein, the

to any gender also applies to any other gender. Defined terms are entirely
capitalized throughout. The section headings are for convenience only and are

the LENDER which is based, directly or indirectly, on this Promissory Note or
any matter in or related to this Promissory Note, including but not limited to
the making of the loan evidenced hereby or the administration or collection

FRONT COVER

The cover of EA Engineering, Science, and Technology, Inc.'s 1997 annual report
depicts a series of artistically-placed "building blocks" against a backdrop of
light and texture. These "building blocks" represent the newly transformed EA, a
firm with a fresh company vision, a rejuvenated staff, an energized management
team, and a client-centered organizational structure. Additionally, the cover of
the report introduces a series of company names and divisions, both formal and
informal, for use in representing and marketing the company's breadth. Those
names, EA Companies, EA Consulting, EA Energy Management Solutions, EA
Laboratories, and EA International, Inc., are subtly placed near each of the
"building blocks."

LETTER TO THE SHAREHOLDERS

We look back on 1997 as a bellweather year, as significant in our Company's
history as was 1973, the year in which EA was founded. This was a year of
redefinition, as the organization confronted the realities of a changing
marketplace and world.

The restructuring of EA has been swift and sure. Guiding this rebirth is our
belief that to succeed today, EA must deliver to its clients more than
compliance with environmental laws--we must assist clients in achieving their
broad business objectives. This belief is reinforced in each of the building
blocks used to cement EA's transformation: a fresh company vision, a revitalized
management team, a new clientcentered organizational structure, and a global
marketing approach that alters the conventional rules of engagement. The result
is a new EA, a bold and exciting company that uses the talents of its
extraordinary professionals to create financial value for its clients.

Since March of 1997, the new management team has dramatically improved the
financial performance of the Company. Profitability was restored and maintained
during the final five months of the fiscal year, with fourth quarter income
higher than in any quarter of the past seven. Record high utilization rates
within the organization, combined with effective management of cost and staffing
levels, have pushed our productivity to the top of industry standards. Emphasis
on cash management, along with a new banking relationship, has created the
necessary foundation for continued improvement in our capital structure. These
achievements are just the beginning.

Company Mission

In our role as an advocate and resource to our clients, EA provides the
management perspective and technical skills needed to anticipate, identify, and
resolve those environmental, energy, and health and safety issues affecting
their business performance and profitability. Recognizing the interrelated
business factors confronting our clients, EA applies the diverse intellectual
capabilities and tactical skills of the entire organization in developing
solutions that are financially responsible, acceptable to regulators,
technically dependable, and operationally efficient.

(A square shaped box is centered over the paragraph.)

Management Team

At the center of the EA transformation you will find the extraordinary
capabilities and dedication of the new management team. This group has been
selected from among the best and brightest in our industry and our Company.
During the final five months of 1997, they have applied great energy and talent
to the task of revitalizing every person in our Company. This new team is driven
to constantly improve profitability, respond to changes in the marketplace, and
provide superior service to our clients. For this team, change is not something
to be endured, it is a way of life.

(A triangle shaped block is centered over the paragraph.)

A Global Marketing Approach

The market for our services is expanding, with the international opportunities
presently exceeding those we see domestically. More important, the distinction
between "domestic" and "international" is diminishing as the world becomes one
global market networked together. These factors are influencing our clients as
well, many of whom see an increasing portion of their expansions occurring in
the developing world.

EA has successfully delivered services in more than 30 countries and continues
an ambitious international business plan. In Alexandria, Egypt, for example, EA
last year completed a multimilliondollar environmental assessment program on
behalf of the US Agency for International Development (USAID) and the Alexandria
General Organization for Sanitary Drainage. EA's project represented the largest
environmental assessment program ever funded by USAID. Our project results will
play a critical role in enabling the City of Alexandria to solve its long-term
resource needs.

In the Western Hemisphere, EA de Mexico received several contracts, including
site characterization and environmental planning work for two cities on behalf
of Mexico's FNM Railroad Authority. In Peru and the Dominican Republic, EA
scientists and planners advised government leaders on programs for the phase-out
of lead-based gasoline.

(A rectangle shaped block is centered over the paragraph.)


At the Center: The Client

We are justifiably proud that "our first client is still our client." For more
than 25 years, EA has maintained a relationship with Baltimore Gas & Electric
Company (BGE). This year, BGE will once again account for about one million
dollars of revenue for EA, with our tasks ranging from stormwater control to
complex remediation of a contaminant-laden retired manufactured gas plant.
Today, nearly 75 percent of our new orders are received from existing clients.
This continuing trust by our clients is our most cherished asset.

<PAGE>

As part of our restructuring, we have created and have focused considerable
authority on our branch offices. This decision follows our belief that being
geographically close to our clients is an essential ingredient to providing
superior client service. In fact, our branch offices are integral parts of the
communities in which they are located. Through participation in civic
organizations and professional societies, our employees understand the
importance of contributing their energies to those activities that make life
better for all. This sense of "partnership" applies to both our professional and
social responsibilities within the communities we serve.

Taken Together

At EA, we understand that "providing superior client service" is more than a
slogan. It requires the dedication of every person in our firm to the goal of
using our intellectual gifts, our creativity, and our commitment to setting us
apart.

As we begin our 25th year, we are determined to demonstrate that understanding
and commitment on a daily basis--in our client relationships, our pursuit of new
opportunities, and in our work with colleagues, suppliers, and shareholders. We
are confident in our new organizational structure and, most importantly, in the
ability of EA's exceptional people to stand second to none in this industry for
quality, talent, and professional performance. EA's evolution is a work in
progress that started in 1997 with our transition from "business as usual" to
business as it should and will be. Armed with that determination and supported
by a revitalized structure, we look forward to 1998.

women of EA Engineering, Science, and Technology. Those talented professionals
nurtured the growth of our Company from a handful of scientists to a
multifaceted firm with diverse capabilities and an enviable reputation for
quality.

This year, a new group of professionals joined our team, injecting fresh ideas
and experience into our firm. The result has been a revitalized EA, one firmly
rooted in the achievements of the past, but strategically positioned to take its
place among the leaders of our industry. I am confident that EA's heritage of 25
years of excellence is a prologue to even greater success."

1997 FINANCIAL OVERVIEW

For EA, 1997 was a momentus year. Following a disappointing second quarter, the
Company launched an ambitious revitalization program centered on cost reduction
and income enhancement. While this restructuring necessitated a sizable loss for
the third quarter, the Companyturned the corner in its fourth quarter, achieving
significant profitability. Profitability in the final quarter of the year
surpassed the results of the firm's seven prior quarters, and returned the
Company to profitability for the first time since the first quarter of 1997.

</TABLE>

Fiscal year 1997 began favorably with a profitable first quarter. However, on a
year-to-year comparative basis, net income as a percentage of gross revenue was
1 percent versus 2.3 percent. This was the beginning of the continued decline of
available work authorizations from federal contracts and a weak private sector
market.

The Company reported a significant loss in the second quarter attributable in
large part to low volume in EA Laboratories, unrecoverable costs on projects,
and higher-than-expected business development expenses.

Realizing the need for rapid change, the Company named a new President and Chief
Executive Officer, Donald A. Deieso, Ph.D., effective March 1, 1997. Quickly
assessing the situation, the management team implemented a major restructuring
plan, which significantly reduced costs and increased profitability. The
anticipated results were achieved by rightsizing, dramatically increasing
utilization rates and productivity, improving cash management, and attracting
fresh financing to the Company.

The loss posted in the third quarter of fiscal 1997 was primarily attributable
to a restructuring charge of $3.0 million and additional estimated costs of $1.4
million in excess of contract values related to certain of the Company's
landfill closure projects, a market EA no longer pursues. The last two months of
the third quarter were profitable, positioning EA for its fourth quarter
success.

The results of the Company's restructuring program were realized in its fourth
quarter with a return to profitability, representing a rise in operating income
of more than $1.2 million over the comparable period from the prior year. This
increase in income was realized on 15 percent lower net revenue. Profitability
improvement has resulted in part from a 20 percent decrease in costs and
operating expenses over the comparable period, including a 10 percent reduction
in interest expense from the prior year.

(A square shaped block is centered above the paragraph.)

Financial Condition

<PAGE>

EA's balance sheet continues to be strong, with minimal long-term debt and
reduced short-term obligations. The Company generated over $1.9 million in cash
from operating activities, much of which was used for debt reduction and
investment in capital equipment, including high-tech computer and
telecommunications capabilities. This in turn reduced working capital and
resulted in a lower current ratio. The Company's debt-to-equity ratio remains
low, below 18 percent.

Improvements made in the Company's billing and collection processes during the
final five months have resulted in a 26-day reduction in Days Sales Outstanding
(DSO) from the prior year. This improvement has reduced our cash borrowings and
interest expense for the year.

Stockholders' equity decreased to $13.3 million, or about $2.13 per share, as a
result of the fiscal 1997 loss, and was partially offset by employee
participation in the Employee Stock Purchase Plan.

(A triangle shaped block is centered above the paragraph.)

Credit Facilities

Adding strength to the Company transformation is the new banking relationship
with The First National Bank of Maryland (FNB). Under the terms of this
agreement, EA has been provided with a revolving credit facility of $8.5
million, of which $2.5 million is available for acquisitions, joint ventures,
and new business opportunities. This new credit facility represents a 42 percent
increase in availability over the previous arrangement. FNB is also making
available an additional $1.5 million for capital equipment. The term of the new
commitment extends until September 30, 1999 and is subject to renewals
thereafter.

          EA ENGINEERING, SCIENCE, AND TECHNOLOGY, INC. & SUBSIDIARIES

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
              FOR THE YEARS ENDED AUGUST 31, 1997, 1996, AND 1995



  Note 1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

  Basis of Presentation--

  The accompanying consolidated financial statements present the accounts of EA
  Engineering, Science, and Technology, Inc. (EA) and its wholly-owned
  subsidiaries, EA International, Inc. and EA Financial, Inc., and its
  wholly-owned subsidiaries, EA Global, Inc. and EA Engineering, Science, and
  Technology de Mexico, S.A. de C.V. During fiscal 1995, EA Remediation
  Technologies, Inc., formerly a wholly-owned subsidiary, was merged into EA.
  The entities are collectively referred to herein as the "Company." All
  significant intercompany transactions have been eliminated in consolidation.

  Revenue Recognition--

  The Company is a multidisciplinary environmental services organization
  providing a wide range of consulting, engineering, remediation, and analytical
  services. These services are generally performed under time and material,
  fixed price, and cost plus fixed fee contracts which vary in length from one
  month to ten years.

  The Company accounts for contract revenues and costs under fixed price
  contracts using the percentageof-completion method. The
  percentage-of-completion is determined using the "cost-to-cost" method for
  each contract cost component. Under this method, direct labor and other
  contract costs incurred to date are compared to periodically revised estimates
  of the total of each contract cost component at contract completion to
  determine the percentage of revenues to be recognized. Revenues from time and
  material and cost plus fixed fee contracts are recognized currently as the
  work is performed. Provision for estimated losses on uncompleted contracts, to
  the full extent of the loss, is made during the period in which the Company
  first becomes aware that a loss on a contract is probable.

  Contract costs and estimated earnings recognized in excess of amounts billed
  are classified as current assets under "costs and estimated earnings in excess
  of billings on uncompleted contracts." Billings in excess of contract costs
  and estimated earnings are classified as current liabilities under "billings
  in excess of costs and estimated earnings on uncompleted contracts."

  Generally, contracts provide for the billing of costs incurred and estimated
  fees on a monthly basis. Amounts included in "costs and estimated earnings in
  excess of billings on uncompleted contracts" in the accompanying financial
  statements will be billed within twelve months of the balance sheet date.

  Major Clients--

  Various agencies of the federal government accounted for approximately 50%,
  53%, and 64% of the Company's net revenue for the years ended August 31, 1997,
  1996, and 1995, respectively.  Additionally,


<PAGE>

  various agencies of the federal government accounted for approximately 40% and
  48% of the Company's accounts receivable and costs and estimated earnings in
  excess of billings on uncompleted contracts as of August 31, 1997 and 1996,
  respectively.

  Cash and Cash Equivalents--

  Cash equivalents consist of money market instruments with a purchased original
  maturity of three months or less, stated at cost, which approximates market.

  Property and Equipment--

  Property and equipment are depreciated using the straight-line method over
  their estimated useful lives ranging from 3 to 10 years. Leasehold
  improvements are amortized over the shorter of the estimated useful life or
  the term of the lease.

  Segment Information--

  The Company operates within one industry segment, providing a wide range of
  consulting, engineering, remediation, and analytical services.

  Reclassifications--

  Certain prior year balances have been reclassified to conform with current
  year presentation.

  Risks and Uncertainties--

  Reliance on major government contracts subjects the Company to risks
  associated with public budgetary restrictions and uncertainties, discrepancies
  between awarded contract amounts and actual revenues, and cancellation at the
  option of the government. The Company attempts to mitigate these risks by
  staffing only to meet reasonably anticipated average workloads, by using
  subcontractors to handle peak workloads, and by obtaining termination benefit
  contract provisions. Cancellation of any of the Company's major government
  contracts, however, could have a material adverse effect on the Company.

  Use of Estimates--

  The preparation of financial statements in accordance with generally accepted
  accounting principles requires management to make estimates and assumptions
  that affect the reported amount of assets, liabilities, revenues and expenses
  in the financial statements and in the disclosures of contingent assets and
  liabilities. While actual results could differ from these estimates,
  management believes that actual results will not be materially different from
  amounts provided in the accompanying consolidated financial statements.

  Supplemental Disclosures of Cash Flow Information--

  Cash paid during the years ended August 31, 1997, 1996, and 1995 for interest,
  was $467,200, $474,200, and $521,700, respectively. Retirements of property
  and equipment for the same periods were $897,200, $2,602,400, and $46,300,
  respectively. The noncash tax benefit attributable to the exercise of non-


<PAGE>

  qualified stock options was $24,600, and $650,900 for the years ended August
  31, 1996 and 1995, respectively. There was no benefit for the year ended
  August 31, 1997.

  Accounting for Income Taxes--

  Deferred income taxes are recorded to reflect the tax consequences on future
  years for differences between the tax basis of assets and liabilities and
  their financial reporting amounts.

  Accounting Pronouncements

  In March 1995, the Financial Accounting Standards Board (FASB) issued SFAS No.
  121 "Accounting for the Impairment of Long-Lived Assets and for Long-Lived
  Assets to be Disposed of." This statement requires that long-lived assets and
  certain identifiable intangibles to be held and used by an entity be reviewed
  for impairment whenever events or changes in circumstances indicate that the
  carrying amount of an asset may not be recoverable. This statement is
  effective for fiscal years beginning after December 15, 1995. Management has
  determined that adoption of this Standard has not resulted in any material
  changes to its financial statements.

  In March 1995, the FASB issued Statement No. 123 (SFAS 123), "Accounting for
  Stock-Based Compensation." Companies have the option of adopting the new
  accounting provisions or may elect to provide pro forma disclosures of net
  income and earnings per share as if the accounting had been adopted.
  Management has elected to continue to account for its stock-based compensation
  in accordance with APB Opinion No. 25 and has provided pro forma disclosures
  (see Note 8).

  In February 1997, the FASB issued Statement No. 128 (SFAS 128), "Earnings Per
  Share," which establishes new standards for computing and presenting earnings
  per share. SFAS 128 is effective for financial statements issued for periods
  ending after December 15, 1997, including interim periods. Management has
  determined that the implementation of SFAS 128 would have no impact on the
  Company's earnings per share amounts.

  In February 1997, the FASB issued Statement No. 129 (SFAS 129), "Disclosure of
  Information about Capital Structure," which eliminates the exemption of
  nonpublic entities from certain disclosure requirements of APB Opinion No. 15
  as provided by FASB Statement No. 21. SFAS 129 is effective for periods ending
  after December 15, 1997. Management has determined that the implementation of
  SFAS 129 will have no impact on the Company's financial reporting.

  In June 1997, the FASB issued Statement No. 130 (SFAS 130), "Reporting
  Comprehensive Income," which establishes standards for reporting and display
  of comprehensive income and its components in a full set of general purpose
  financial statements. SFAS 130 is effective for fiscal years beginning after
  December 15, 1997. Management has not yet determined whether the
  implementation of SFAS 130 will have any impact of the Company's financial
  reporting.

  In July 1997, the FASB issued Statement No. 131 (SFAS 131), "Disclosures About
  Segments of an Enterprise and Related Information," which establishes a new
  approach for determining segments within a company and reporting information
  on those segments. SFAS 131 is effective for fiscal years beginning after
  December 15, 1997. Management has not yet determined whether the
  implementation of SFAS 131 will have any impact on the Company's current
  method of disclosing business segment information.

  Note 4.  BANK FINANCING ARRANGEMENTS:

  The Company entered into a new credit arrangement with a regional bank during
  fiscal year 1997 consisting of: (i) an $8,500,000 revolving line of credit
  secured by receivables; (ii) a $500,000 term loan; and (iii) an equipment line
  of credit of $1,500,000. Of the $8,500,000 revolving line of credit,
  $2,500,000 is available for acquisitions, joint ventures and licensing
  agreements. Borrowings under the revolving line of credit are limited to a
  percentage of certain accounts receivable and costs and estimated earnings in
  excess of billings on uncompleted contracts (up to a maximum of $4,000,000).
  The agreement was effective August 22, 1997. During fiscal years 1997, 1996,
  and 1995, the Company was either in compliance or had obtained waivers on all
  covenants related to these and prior arrangements.

  daily interest expense and the daily average balance outstanding. For the year
  ended August 31, 1997, the Company only maintained short-term borrowing
  balances during the months of April through August. Prior to April and at the
  end of August 1997, all borrowings were considered long term. For the year
  ended August 31, 1996, short-term balances were for nine months through May
  31, 1996.

  Note 5.  LEASE COMMITMENTS:

  The Company's central office, laboratory facilities, regional offices, and
  certain furniture and equipment are held under operating leases. These leases
  expire at various dates through fiscal 2007, and certain leases call for
  annual proportionate increases due to property taxes and certain other
  operating expenses. Lease expense amounted to $8,030,200, $8,912,300, and
  $8,469,300 for the years ended August 31, 1997, 1996, and 1995, respectively.
  Lease expense included payments of approximately $2,016,500, $2,054,900, and
  $1,985,300 for years ended August 31, 1997, 1996, and 1995, respectively, to
  partnerships consisting of the Chairman of the Board of EA and certain members
  of his family for its central office, and Loveton, Maryland, regional office
  and laboratory facility. These payments include reimbursements of
  approximately $965,000 per year for pass-through taxes and operating expenses
  incurred by the lessor which include local property taxes, janitorial and
  mechanical equipment maintenance, and utility costs related to the operation
  of both office and laboratory leased space. Management of the Company believes
  the terms and conditions of the transactions between the Company and entities
  with which the Chairman is affiliated, are at least as favorable to the
  Company as could have been obtained from third parties and are in the best
  interest of the Company.

  The minimum lease commitments under noncancellable operating leases are as
follows:

  Note 6.  NET INCOME (LOSS) PER SHARE:

  Net income (loss) per share is based on the weighted average number of shares
  of common stock and common stock equivalents outstanding during the period,
  and have been adjusted retroactively to reflect two 3 for 2 stock splits,
  effected in the form of 50% stock dividends wherein, on February 23, 1994 and
  July 5, 1994, 1 additional share of stock was issued for each 2 shares
  outstanding as of the record dates of February 8, 1994 and June 28, 1994,
  respectively. Common stock equivalents are calculated using the treasury stock
  method. All disclosures with regard to the shares of common stock have been
  adjusted to reflect these stock splits.


  Note 7.  PROFIT SHARING:

  EA maintains a defined contribution plan in which all employees who are at
  least 21 years of age and have completed six months of credited service, as
  defined by the plan, are eligible to participate. The plan provides for
  discretionary employer contributions for each fiscal year, in amounts
  determined annually by the Board of Directors. The plan also includes a 401(k)
  provision, allowing for Company matching contributions. For the years ended
  August 31, 1997, 1996, and 1995, matching contributions to the plan made under
  the 401(k) provisions of the plan, were $534,900, $729,200, and $710,400,
  respectively. Certain officers and stockholders of the Company serve as
  trustees to the plan, as appointed by the Board of Directors.


  Note 8.  STOCK OPTION AND EMPLOYEE STOCK PURCHASE PLANS:

  The Company maintains a Stock Option Plan (the Plan), which provides for the
  grant of nonqualified stock options and incentive stock options to certain key
  employees and officers of the Company. The exercise price of an option granted
  under the Plan may not be less than the fair market value of the underlying
  shares of Common Stock on the date of the grant. A total of 580,200 options
  are issued and outstanding as of August 31, 1997 having an average exercise
  price of $2.34. Of the outstanding options, 200,000 were granted to Donald A.
  Deieso on February 26, 1997 when he joined the Company as President and CEO.
  The exercise amount of the 200,000 shares is $2.25, which was equal to the
  market price on the grant date. There are 340,000 options available for
  issuance as of August 31, 1997.

  The Company maintains an Employee Stock Purchase Plan to provide eligible
  employees with the opportunity to purchase shares of the Company's Common
  Stock through voluntary payroll deductions. Under the Plan, eligible employees
  may purchase shares through monthly payroll deductions at 95% of current
  market value at the time of purchase. The Company pays all administrative
  expenses related to employee purchases. A total of 155,400 shares remain
  authorized for distribution under the Plan as of August 31, 1997.

  The Company maintains two Non-Employee Director Stock Option Plans (1993 and
  1995) which provide for the granting of nonqualified stock options to its
  non-employee directors. The exercise price of the 36,000 options, which were
  outstanding as of August 31, 1997 ranged between $2.375 and $6.125, which
  equaled the fair market value at the dates of grant. A total of 41,500 options
  remain reserved for the Director Stock Option Plans as of August 31, 1997.

<PAGE>

  The Company accounts for these plans under APB Opinion No. 25, under which no
  compensation cost has been recognized. Had compensation cost for plans been
  determined consistent with FASB Statement No. 123, the Company's net loss and
  loss per share would have changed the following pro forma amounts:


                                               1997             1996

  Note 9.  COMPANY RESTRUCTURING

  On March 25, 1997 the Company announced a major organizational realignment to
  reposition itself in the marketplace. In connection with the restructuring,
  the Company incurred charges of $3,000,100 during the third quarter related to
  severance, planned reduction in office space, the suspension of the
  implementation of a new project/financial system, and other related costs.

<PAGE>

  This restructuring included a staff reduction of approximately 125 employees.

  As of August 31, 1997, the Company had accruals of $880,100 included as other
  current liabilities in the accompanying consolidated balance sheet for costs
  to be incurred in future periods.

  Note 10.  RELATED PARTY TRANSACTIONS

  At the request of its former primary lender and in order to maintain its
  favorable relationship with that lender, the Company in December 1996
  purchased from this lender the secured loans of three EA officers. These
  interest-free demand loans, in the aggregate amount of $301,000, are secured
  by pledges of the Company's common stock.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

  To the Board of Directors and Stockholders of
  EA Engineering, Science, and Technology, Inc.:

  We have audited the accompanying consolidated balance sheets of EA
  Engineering, Science, and Technology, Inc. (a Delaware corporation) and
  subsidiaries as of August 31, 1997 and 1996, and the related consolidated
  statements of operations, changes in stockholders' equity and cash flows for
  each of the three years in the period ended August 31, 1997. 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 EA Engineering, Science, and
  Technology, Inc. and subsidiaries as of August 31, 1997 and 1996, and the
  results of their operations and their cash flows for each of the three years
  in the period ended August 31, 1997, in conformity with generally accepted
  accounting principles.

  Marketing for the Registrant's Common Equity and Related Stockholder Matters

  On October 31, 1986, EA common stock began public trading in the
  over-the-counter market under the symbol "EACO." The following table shows the
  high and low closing sales price reported on the NASDAQ National Market
  System. Such over-the-counter market quota-tions, however, reflect interdealer
  prices, without retail markup, markdown, or commission and may not necessarily
  represent actual transactions. These prices are adjusted to reflect EA's two 3
  for 2 splits, each effected in the form of a 50 percent stock dividend on
  January 25, 1994 and June 14, 1994.
