                              PROSPECTUS SUMMARY
    
     This is a summary of the information contained in this prospectus. To
understand this offering fully, you should read the entire prospectus,
especially the risk factors and financial statements.

     As of the date of this prospectus, all of the stockholders of Litronic
Industries, Inc. will exchange all of the outstanding common stock of that
company for all of the outstanding common stock of Litronic Inc.  Upon the
closing of this offering, the newly reorganized Litronic Inc. will acquire all
of the outstanding common stock of Pulsar Data Systems, Inc.

     In this prospectus, unless the context indicates otherwise, the term
"Litronic" refers to Litronic Inc. and its subsidiaries, after giving effect to
its reorganization with Litronic Industries, Inc., and the terms "we," "our" or
"our company" refer to Litronic Inc. and its subsidiaries after giving effect to
both its reorganization with Litronic Industries, Inc. and its acquisition of
Pulsar.

     The historical financials for Litronic in this prospectus have been
retroactively adjusted to reflect the reorganization.  Since Litronic Inc. has
had no operations of its own, the information presented in those financials,
other than the capital structure, relates solely to Litronic Industries, Inc.
The pro forma financial data in this prospectus has been prepared to illustrate
the effect of the Pulsar acquisition and this offering on data derived from
Litronic's historical financials.

                                  OUR COMPANY

OUR BUSINESS

     Litronic provides professional Internet data security services and develops
and markets software and microprocessor-based products needed to secure
electronic commerce and communications over the Internet and other
communications networks based on Internet protocols. To increase sales capacity
for its proprietary products and to capitalize on opportunities in the rapidly
growing Internet-based information technology security market, Litronic is
acquiring Pulsar, a network integration solutions company that develops large-
scale network solutions for commercial and government organizations.

OUR PRODUCTS

     Our primary data security products use an advanced form of computer
security technology referred to as public key infrastructure, or PKI, which is
the standard technology for securing Internet-based commerce and communications.
As a result, our products enable customers to integrate PKI security into their
Internet networks, existing database applications and customized software
applications.     

                                      -3-
<PAGE>
 
    
     Our data security products can be used with world-wide-web browsers,
including Netscape Communicator and Microsoft Internet Explorer, to provide
secure E-mail or other data communications and facilitate secure electronic
commerce transactions.  In addition, our products use digital certificate
technology to uniquely identify the sender of an electronic message.  Digital
certificates can be securely contained in hardware tokens, such as PKI cards and
secure-keys, and in software tokens, such as the software security files found
in most web browsers.  Our products also support numerous types of operating
systems and facilitate the process of issuing, managing and recovering digital
certificates throughout a customer's enterprise.

     In addition, we are currently developing PKI cards that will be capable of
integrating multiple digital certificates, provide for greater processing power,
versatility and storage capacity than today's conventional PKI cards, and still
be credit card sized and competitively priced. Working with Atmel Corporation, a
leading semi-conductor manufacturer, we are leading the development of the Forte
microprocessor.  Under a contract with the National Security Agency some of 
our development efforts for this project are being reimbursed.  We are designing
this 32-bit RISC microprocessor to be embeded in an advanced PKI card that we
are developing. We expect our Forte PKI card to be the fastest, most versatile
and most cryptographically advanced PKI card available.

     We have also established strategic relationships with other industry
leaders who have adopted PKI as a core feature of their secure product
offerings, including:

     . Netscape Communications Corporation    . Microsoft Corporation
     . VeriSign, Inc.                         . International Business Machines
     . RSA Data Security, Inc.                  Corp.
     . Atmel Corporation                      . SCM Microsystems, Inc.
                                              . U.S. National Security Agency

OUR CUSTOMERS

     Our data security customers come from diverse industries, such as the
finance, healthcare, telecommunications, electronic commerce and government
industries, and include:

     . Bank of America                    . VeriSign, Inc.
     . Lucent Technologies Inc.           . Lockheed Martin Corporation
     . Deloitte & Touche LLP              . Netscape Communications Corporation
     . the U.S. Army Corps of Engineers   . Schlumberger Limited
     . the National Security Agency       . Nippon Telegraph and
                                            Telecommunications Data Corporation

     In addition, our newly acquired Pulsar client base will include over 100
federal agencies, such as the Executive Offices of the President of the United
States, the Federal     

                                      -4-

Bureau of Investigation and the Federal Communications Commission, as well as
over 40 commercial, state and local customers.

OUR MARKET AND MARKET OPPORTUNITY

     The increasing proliferation of, and reliance upon, Internet communications
and transactions has caused data security to become a paramount concern.  Demand
for information security products is forecast by Datamonitor, an independent
research firm, to increase from $1.6 billion in 1997 to almost $7.0 billion by
2001, an annual growth rate of 44%.  In addition, Datamonitor forecasts the PKI
segment to be the fastest growing segment of the Internet security market, with
the demand for PKI-based products increasing from $75 million in 1997 to
approximately $1.9 billion by 2001, an annual growth rate of 124%.

OUR STRATEGY

     We intend to leverage the direct sales force, distribution channels and
strategic partners of our new Pulsar operations to aggressively expand our data
security distribution capabilities. Pulsar's strategic partners include
electronic commerce companies, Internet service providers, value-added
resellers, systems integrators and original equipment manufacturers.  In
addition, we believe that our newly acquired network integration solutions
expertise will provide us with significant competitive advantages with respect
to our Internet data security offerings, as the implementation of Internet
network security solutions and infrastructure requires specialized skills which
are typically limited in corporate information technology departments.

     To capitalize on the expanding market opportunities in the information
security market, we intend to exploit:

     .    the substantial experience and knowledge of Litronic's existing
          management team in the Internet data security, computer networking and
          semi-conductor industries, and

     .    Pulsar's extensive expertise in the sale and implementation of large-
          scale networking systems, as well as its significant market access.

OUR POTENTIAL ACQUISITION OF THE ASSURE TECHNOLOGY

     Subject to our due diligence review, we expect to enter into an agreement
under which we will, after the close of this offering, bid shares of our common
stock valued at $6.0 million in a foreclosure sale for the purchase of the
proprietary encryption-based information security technology for client/server
networks and related intellectual property known as the Assure technology. If
our bid is the winning bid, we will seek to complete the development of products
based on this technology in order to expand our data security product offerings.

     The judgment holders in the foreclosure action hold judgments in the
aggregate amount of approximately $6.0 million.  Included among these judgment
holders are      

                                      -5-
<PAGE>
 
    
affiliates of BlueStone, who hold judgments aggregating approximately $750,000,
including a judgment in the amount of approximately $150,000 held by Anthony
Giraudo, a director nominee of our company and a limited partner of BlueStone.
If our bid is the winning bid at the foreclosure sale, all of the judgment
holders, including the BlueStone affiliates, will receive their proportionate
percentage of the shares of our common stock included in the bid. See "Certain 
Transactions."

                                 RISK FACTORS
    
     An investment in our common stock is speculative and involves a high degree
of risk.  In addition to the other information in this prospectus, you should
carefully consider the following risk factors in evaluating our company and our
prospects before purchasing shares of our common stock.

WE HAVE A HISTORY OF LOSSES AND MAY INCUR FUTURE LOSSES.

     Even with the proceeds of this offering, we may not become profitable or
significantly increase our revenue.  Litronic incurred a net loss of $1.4
million for the year ended December 31, 1998.  Pulsar incurred net losses of
$7.4 million for the year ended December 31, 1998 and $11.0 million for the year
ended December 31, 1997.  Our pro forma combined statement of operations
reflects a net loss of $10.4 million for the year ended December 31, 1998.

PULSAR'S INDEPENDENT AUDITORS HAVE EXPRESSED DOUBT ABOUT PULSAR'S ABILITY TO
CONTINUE AS A GOING CONCERN.

     For the year ended December 31, 1998, Pulsar's independent auditors noted
in their report that as a result of Pulsar's loss, its net capital deficiency
and its default on financing agreement debt covenants, there was a substantial
doubt about Pulsar's ability to continue as a going concern. After this
offering, we will have positive working capital and be in compliance with all
financing debt agreements. We believe working capital, including proceeds from
this offering, and available borrowings under credit facilities will be
sufficient to satisfy our cash flow requirements for at least the 12 months
following this offering.

OUR INABILITY TO INTEGRATE, OR IMPLEMENT OUR PLANS FOR, THE OPERATIONS OF PULSAR
MAY ADVERSELY AFFECT OUR BUSINESS.

     Integration of the Pulsar acquisition may place strain on our managerial
and financial resources, which could, in turn, adversely affect our business. To
achieve the full benefits of the Pulsar acquisition, we will need to:

     .    integrate our administrative, financial and engineering resources; 
     .    coordinate our marketing and sales efforts; and
     .    implement appropriate operational, financial and management
          systems and controls.

We may not be able to successfully integrate Pulsar's operations.  In addition,
we are acquiring Pulsar assuming that we can roll out our enterprise-wide data
security products to Pulsar's existing client base, successfully complete the
implementation of Pulsar's recent shift in product reselling focus, expand
Pulsar's professional service offerings and increase sales of Pulsar's products
and professional services to commercial customers and state and local
governments. We may not be able to successfully implement any of these plans.
Our     

                                      -14-
<PAGE>
 
    
failure to do so would significantly diminish the value of the Pulsar
acquisition and adversely affect our future operations.

THE GOODWILL AND OTHER INTANGIBLES ACQUIRED IN THE PULSAR ACQUISITION MAY HAVE
AN ADVERSE IMPACT ON OUR OPERATING RESULTS AND THE MARKET PRICE OF OUR COMMON
STOCK.

     Approximately $32.2 million, or 53%, of our pro forma combined, as
adjusted, assets as of December 31, 1998, consisted of intangible assets,
including goodwill, arising from the acquisition of Pulsar. This amount, which
will be amortized over 15 years, constitutes a non-cash expense in each
amortization period, which is not deductible for tax purposes, that will reduce
net income or increase net loss for that period. The reduction in our net
earnings or an increase in our net loss resulting from the amortization of
goodwill and other intangibles may have an adverse impact on our operating
results and the market price of our common stock. There is also a risk that we
may never realize the value of our intangible assets.

A DEFAULT UNDER OUR SECURED CREDIT ARRANGEMENTS COULD RESULT IN A FORECLOSURE OF
OUR ASSETS BY OUR CREDITORS.

     All of our assets are pledged as collateral to secure portions of our debt.
As of December 31, 1998, Litronic had $5.8 million and Pulsar had $13.6 million
in outstanding secured debt.  We expect to enter into a new $20.0 million credit
facility following this offering which will also be secured by a pledge of all
of our assets.  This means that if we default on our secured debt obligations
the lenders could foreclose on our assets.  From time to time we have been in
violation of financial covenants under our existing credit arrangements and have
received either waivers for these violations or forbearance agreements through
the date of this prospectus. Although we expect to be in compliance with all of
our financial covenants upon the closing of this offering, if we fail to comply
with our secured debt loan covenants or otherwise default on our obligations in
the future without obtaining waivers or forbearance agreements for these
violations, our indebtedness could become immediately due and payable and the
lenders could foreclose on our assets.

THE TERMS OF OUR LOAN AGREEMENTS COULD LIMIT OUR ABILITY TO IMPLEMENT OUR
BUSINESS STRATEGY.

     The terms of our loan agreements with our credit providers could limit our
ability to implement our strategy.  In addition to substantially prohibiting us
from incurring additional indebtedness, our loan agreements with these creditors
generally limit or prohibit us from:

     .    declaring or paying cash dividends; 
     .    making capital distributions or other payments to stockholders;
     .    merging or consolidating with another corporation; or
     .    selling all or substantially all of our assets.    

                                      -15-
<PAGE>
 
    
WE DERIVE A SUBSTANTIAL PORTION OF OUR REVENUE FROM A SMALL NUMBER OF CUSTOMERS
AND, THEREFORE, THE LOSS OF EVEN ONE OF THESE CUSTOMERS COULD SIGNIFICANTLY AND
NEGATIVELY IMPACT OUR OPERATING RESULTS.

     We depend on a limited number of customers for a substantial portion of our
revenue and many of our contracts with our significant customers are short-term
contracts.  For the year ended December 31, 1998, Litronic derived 81% of its
revenue from three customers and Pulsar derived 23% of its revenue from one
customer.  The nonrenewal of any significant contract upon expiration or, a
substantial reduction in sales to any of our significant customers, would
adversely affect our business unless we were able to replace the revenue we
received from these customers. We expect to continue to depend upon a limited
number of large customers for a substantial portion of our revenue.

DOING BUSINESS WITH THE U.S. GOVERNMENT ENTAILS MANY RISKS WHICH COULD ADVERSELY
AFFECT US.

     Sales to U.S. government agencies accounted for 90% of our pro forma
combined revenue for the year ended December 31, 1998. Our sales to these
agencies are subject to risks, including:

     .    potential reduction in the federal funding available for them to
          purchase our products and services;

     .    early termination of our contracts;

     .    disallowance of costs upon audit;

     .    changes in the government contract procurement process; and

     .    the necessity to participate in competitive bidding and proposal
          processes.


     In addition, the government may be in a position to obtain greater rights
with respect to our intellectual property than we would grant to other entities.
Government agencies also have the power, based on financial difficulties or
investigations of its contractors, to deem contractors unsuitable for new
contract awards.  Because we engage in the government contracting business, we
have been and will be subject to audits and may be subject to investigation by
governmental entities.  Failure to comply with the terms of any of our
governmental contracts could result in substantial civil and criminal fines and
penalties, as well as our suspension from future government contracts for a
significant period of time, any of which could adversely affect our business.

IF USE OF THE INTERNET AND OTHER COMMUNICATIONS NETWORKS BASED ON INTERNET
PROTOCOLS DOES NOT CONTINUE TO GROW, DEMAND FOR OUR PRODUCTS MAY NOT INCREASE.

     Increased demand for our products depends in large part on the continued
growth of the Internet and Internet protocol-based networks and the widespread
acceptance and use      

                                      -16-
<PAGE>
 
    
of these mediums for electronic commerce and communications. Because electronic
commerce and communications over these networks are evolving, we cannot predict
the size of the market and its sustainable growth rate. A number of factors may
affect market size and growth rate, including:

     .    the use of electronic commerce and communications may not increase, or
          may increase more slowly than we expect, as a result of the cost of
          the infrastructure required to support its widespread use;

     .    the Internet may continue to experience significant growth both in the
          number of users and the level of use, but the Internet infrastructure
          may not be able to continue to support the demands placed on it by
          continued growth;

     .    continued growth may affect the Internet's performance and
          reliability;

     .    the growth and reliability of electronic commerce and communications
          could be harmed by delays in development or adoption of new standards
          and protocols to handle increased levels of activity or by increased
          governmental regulation; and

     .    changes in, or insufficient availability of, communications services
          to support electronic commerce and communication could result in poor
          performance and also adversely affect usage.

THERE ARE RISKS RELATING TO OUR OFFER TO PURCHASE THE ASSURE TECHNOLOGY.

     Although we expect, subject to our due diligence review, to enter into an
agreement under which we will agree to bid at least $6.0 million of our common
stock to purchase the Assure technology, we do not, at this time, know how many
shares we will have to include in our bid because we cannot be certain at what
price our common stock will be trading during the five-day measurement period
prior to the foreclosure sale. Based on the initial public offering price and
assuming an initial public offering price of $10.00 per share, our bid would
consist of at least 600,000 shares of our common stock. However, if, at the time
of our bid, the average closing price of our common stock on Nasdaq during the
measurement period is below the initial public offering price, we will have to
bid more shares. In addition, regardless of the number of shares which are
included in our bid, our bid for the Assure technology may not be the winning
bid in the foreclosure sale and, thus, we may not be able to acquire the
technology.

     In addition, even if we successfully acquire the Assure technology, our
failure to upgrade the technology and complete the development of products based
on the technology would adversely affect our business.  Our development efforts
will be subject to many risks, including:

     .    we were not involved in the initial development of the technology and
          will need to devote financial and personal resources to become
          familiar with the technology;     

                                      -17-
<PAGE>

     
     .    we may not become sufficiently familiar with the technology to upgrade
          the technology or develop products based on the technology in a cost
          effective or timely manner, or at all;

     .    we may face technical problems or other difficulties or other
          significant delays; and

     .    in addition to the stock we would issue if our bid was the winning
          bid, we have allocated $1.2 million of the net proceeds of this
          offering to the development of Assure-based products and we may expend
          this and significant additional resources without ever successfully
          developing a commercial product.

     In addition, there may be an adverse impact on our operating results due to
in-process research and development charges and/or amortization of assets
related to the purchase of the Assure technology.  See "Certain Transactions."

SOME OF OUR PRODUCTS AND SERVICES HAVE LENGTHY SALES AND IMPLEMENTATION CYCLES
WHICH, IF DELAYED, COULD ADVERSELY AFFECT FORECASTED OPERATING RESULTS.

     Evaluating customers' data security needs and designing and implementing
custom networks typically requires significant expenditure of time, capital and
other resources.  Customers' purchasing decisions for our products and systems
may be subject to delay due to many factors not within our control, such as the
significant expense of many data security products and network systems,
customers' internal budgeting process, year 2000 concerns and the other
procedures customers may require for the approval of large purchases.  Further,
the implementation process is subject to delays resulting from administrative
concerns associated with incorporating new technologies into existing networks,
deployment of a new network system and data migration to the new system.  The
sales and implementation cycles associated with our product sales and network
design and implementation activities can, as a result, be lengthy, potentially
lasting from 45 to 90 days.  Our quarterly and annual operating results could be
adversely affected if sales forecasted for a particular quarter from a
particular customer are delayed.

IF PKI TECHNOLOGY IS COMPROMISED, OUR BUSINESS WOULD BE ADVERSELY AFFECTED.

     Many of our products are based on PKI technology, which involves the use of
a public key and a private key to encrypt and decrypt messages. The security
afforded by this technology depends on the integrity of a user's private key,
which depends in part on the application of algorithms, or advanced mathematical
factoring equations. This integrity is based on the premise that factoring large
numbers into their prime number components is difficult. The occurrence of any
of the following could result in a decline in demand for our data security
products:

     .    development of an easy factoring method would reduce or eliminate
          security of encryption products using PKI technology;     

                                      -18-
<PAGE>
 
    
     .    any significant advance in techniques for attacking PKI systems could
          render some or all of our products based on cryptographic technology
          obsolete or unmarketable;

     .    computer systems significantly faster and more powerful than those
          presently available could theoretically solve factoring problems even
          without a breakthrough in factoring or other methods of attacking PKI
          systems;

     .    publicity of the successful decoding of cryptographic messages or the
          misappropriation of private keys, as has happened in the past, could
          adversely affect public perception as to the safety of PKI technology;
          and

     .    current or future government regulation regarding the use, scope and
          strength of PKI could limit our ability to develop and sell products
          with encryption technology strong enough to maintain the integrity of
          a user's private key against factoring by more powerful computer
          systems.


IF WE DO NOT RESPOND TO RAPID TECHNOLOGICAL CHANGES, OUR PRODUCTS AND SERVICE
OFFERINGS COULD BECOME OBSOLETE.

     The markets we serve are characterized by rapidly changing technology,
emerging industry standards and frequent introduction of new products. The
introduction of products embodying new technologies and the emergence of new
industry standards may render our products obsolete or less marketable.  The
process of developing our products and services is extremely complex and
requires significant continuing development efforts.  If we are unable to modify
existing products and develop new products that are responsive to changing
technology and standards and meet customer needs in a timely and cost effective
manner, our business could be adversely affected.

IF WE FAIL TO ESTABLISH AND MAINTAIN STRATEGIC RELATIONSHIPS, OUR ABILITY TO
DEVELOP AND MARKET OUR PRODUCTS WOULD BE ADVERSELY AFFECTED.

     The loss of any of our existing strategic relationships, or our inability
to create new strategic relationships in the future, could adversely affect our
ability to develop and market our products. We depend upon our partners to
develop and market products and to fund and otherwise perform their obligations
as contemplated by our agreements with them. We do not control the time and
resources devoted by our partners to these activities. These relationships may
not continue or may require us to spend significant financial, personnel and
administrative resources from time to time. We may not have the resources
available to satisfy our commitments, which may adversely affect our strategic
relationships. Further, our products and services may compete with the products
and services of our strategic partners. This competition may adversely affect
our relationships with our strategic partners, which could adversely affect our
business.    

                                      -19-
<PAGE>
 
    
WE DEPEND ON KEY MANAGEMENT PERSONNEL.

     Our success will depend largely on the continuing efforts of our executive
officers and senior management, especially those of Kris Shah, our chairman of
the board and chief executive officer, and William W. Davis, Sr., our president
and chief operating officer.  Our business may be adversely affected if the
services of any of our key personnel become unavailable to our company.  We have
not entered into employment agreements with any employees other than Messrs.
Shah and Davis, and even with these agreements there is a risk that these
individuals will not continue to serve for any particular period of time.  While
we intend to obtain key person life insurance policies on the lives of Messrs.
Shah and Davis, each in the amount of $3.0 million, these amounts may not be
sufficient to offset the loss of their services.

THERE IS SIGNIFICANT COMPETITION IN OUR INDUSTRY FOR HIGHLY SKILLED EMPLOYEES
AND OUR FAILURE TO ATTRACT AND RETAIN TECHNICAL PERSONNEL WOULD ADVERSELY AFFECT
OUR BUSINESS.

     We may not be able to successfully attract or retain highly skilled
employees.  Our inability to hire or retain highly qualified individuals may
impede our ability to develop, install, implement and otherwise service our
software and hardware systems, customers and potential customers or otherwise
efficiently conduct our operations, all of which may adversely affect our
business.  The data security and networking solution industries are
characterized by a high level of employee mobility, and the market for highly
qualified individuals in the computer-related fields is intense.  This
competition means there are fewer highly qualified employees available to hire,
the costs of hiring and retaining these individuals are high and these personnel
may not remain with our company once hired.  Furthermore, there is increasing
pressure to provide technical employees with stock options and other equity
interests in our company, which may dilute earnings per share.

POTENTIAL PRODUCT DEFECTS COULD SUBJECT US TO CLAIMS FROM CUSTOMERS.     

     Products as complex as those we offer may contain undetected errors or
result in failures when first introduced or when new versions are released.
Despite our product testing efforts and testing by current and potential
customers, it is possible that errors will be found in new products or
enhancements after commencement of commercial shipments. The occurrence of these
errors could result in adverse publicity, delay in product introduction,
diversion of resources to remedy defects, loss of or a delay in market
acceptance or claims by customers against our company, or could cause us to
incur additional costs, any of which could adversely affect our business.
    
WE MAY BE EXPOSED TO POTENTIAL LIABILITY FOR ACTUAL OR PERCEIVED FAILURE TO
PROVIDE REQUIRED PRODUCTS OR SERVICES.

     Because our customers rely on our products for critical security
applications, we may be exposed to potential liability claims for damage caused
to an enterprise as a result of an actual or perceived failure of our products.
An actual or perceived breach of enterprise network or data security systems of
one of our customers, regardless of whether the breach is attributable to 
our     

                                      -20-
<PAGE>
 
    
products or solutions, could adversely affect the market's perception of our
company, products and solutions and therefore our business.

     Furthermore, the nature of many of our professional services exposes us to
a variety of risks. Many of our professional service engagements involve
projects that are critical to the operations of our customers' businesses. Our
failure or inability to meet a customer's expectations in the performance of our
services, or to do so in the time frame required by the customer, regardless of
our responsibility for the failure could

     .    result in a claim for substantial damages against us by the customer;
     .    discourage customers from engaging us for these services; or
     .    damage our business reputation.

     In addition, as a professional services provider, a portion of our business
involves employing people and placing them in the workplace of other businesses.
Therefore, we are also exposed to liability for actions taken by our employees
while on assignment, such as:

     .    damages caused by employee errors and omissions;
     .    misuse of customer proprietary information;
     .    misappropriation of funds;
     .    discrimination and harassment;
     .    theft of customer property;
     .    other criminal activity or torts; and
     .    other claims.

WE MAY NOT HAVE SUFFICIENT INSURANCE TO COVER POTENTIAL LIABILITIES.

     Although we maintain general liability insurance coverage, that insurance
may not continue to be available to us on commercially reasonable terms or in
sufficient amounts to cover one or more large claims, or the insurer may
disclaim coverage as to any future claim. The successful assertion of one or
more large claims against us that exceed available insurance coverage, or
changes in our insurance policies, including premium increases or the imposition
of large deductibles or co-insurance requirements, could adversely affect our
business.

PROBLEMS RELATING TO THE YEAR 2000 ISSUE COULD ADVERSELY AFFECT OUR BUSINESS.

     We are in the process of surveying our major vendors regarding year 2000
compliance. Until we complete our survey we cannot fully assess the year 2000
status of any of our vendors or suppliers.  The failure of our significant
vendors and customers to make their products and systems year 2000 compliant may
adversely affect the performance of our products, which may in turn adversely
affect our business.  It is possible that customers or third parties might seek
indemnification or damages from us as a result of year 2000 issue-related errors
caused by or not prevented by our products of services.  We cannot predict the
extent to which we might be liable for these costs, but it is conceivable in
general that year 2000     

                                      -21-
<PAGE>
 
    
errors could result in substantial judgments against providers of information
technology such as our company. If we were to suffer an adverse judgment as a
result of prior year 2000 noncompliance of our products, it may have an adverse
impact on our business.

     Customers' purchasing decisions could be affected by the year 2000 issue as
they may need to expend significant resources to correct their existing systems.
This situation may result in reduced funds available to implement the
infrastructure needed to conduct trusted and secure electronic commerce and
communications over the Internet, intranets and extranets.  These factors could
lead to a decline in sales of our products and services, which could, in turn,
adversely affect our business.

     The extent of the potential impact of the year 2000 issue generally is not
known, and we cannot predict the likelihood that the year 2000 issue will cause
a significant disruption in the economy as a whole.

OUR PARTICIPATION IN COMPETITIVE BIDDING FOR CONTRACTS EXPOSES US TO THE
POTENTIAL LOSS OF FINANCIAL AND OTHER RESOURCES.

     We generate a portion of our revenue from contracts and purchase orders
awarded through the competitive bidding process.  Our bids may not be accepted
or, if accepted, awarded contracts may not generate sufficient revenue to result
in profitable operations.  The competitive bidding process is typically lengthy
and often results in the expenditure of financial and other resources in
connection with bids that are not accepted.  Additionally, inherent in the
competitive bidding process is the risk that our costs may exceed projected
costs upon which a submitted bid or contract price is based.

WE FACE INTENSE COMPETITION FROM A NUMBER OF SOURCES.

     The markets for our products and services are intensely competitive and, as
a result, we face significant competition from a number of different sources. We
may be unable to compete successfully as many of our competitors are more
established, benefit from greater name recognition and have substantially
greater financial, technical and marketing resources than we have. In addition,
there are several smaller and start-up companies with which we compete from time
to time. We also expect that competition will increase as a result of
consolidation in the information security technology and product reseller
industries.

THIRD PARTIES COULD OBTAIN ACCESS TO OUR PROPRIETARY INFORMATION OR
INDEPENDENTLY DEVELOP SIMILAR TECHNOLOGIES BECAUSE OF THE LIMITED PROTECTION FOR
OUR INTELLECTUAL PROPERTY.

     Notwithstanding the precautions we take, third parties may copy or
otherwise obtain and use our proprietary technologies, ideas, know-how and other
proprietary information without authorization or independently develop
technologies similar or superior to our technologies. In addition, the
confidentiality and non-competition agreements between us and our employees,
distributors, and clients may not provide meaningful protection     

                                      -22-
<PAGE>
 
    
of our proprietary technologies or other intellectual property in the event of
unauthorized use or disclosure. Policing unauthorized use of our technologies
and other intellectual property is difficult, particularly because the global
nature of the Internet makes it difficult to control the ultimate destination or
security of software or other data transmitted. Furthermore, the laws of other
jurisdictions may afford little or no effective protection of our intellectual
property rights. Our business, financial condition and operating results could
be adversely affected if we are unable to protect our intellectual property
rights.

WE MAY FACE CLAIMS OF INFRINGEMENT OF PROPRIETARY RIGHTS.

     There is a risk that our products infringe the proprietary rights of third
parties.  While we do not believe that our products infringe on proprietary
rights of third parties, infringement or invalidity claims may nevertheless be
asserted or prosecuted against us and our products may be found to have
infringed the rights of third parties.  If any claims or actions are asserted
against us, we may be required to modify our products or may seek to obtain a
license for these intellectual property rights in a timely manner.  We may not
be able to modify our products or obtain a license on commercially reasonable
terms, or at all.  Our failure to do so could adversely affect our business.

OUR BUSINESS COULD BE ADVERSELY AFFECTED BY CURRENT AND POSSIBLE FUTURE
GOVERNMENT REGULATION.

     As a result of government regulation of our products, we may be at a
disadvantage in competing for international sales compared to foreign companies
that are not subject to these restrictions.  This could adversely affect our
business.  Because we sell our products internationally, we must comply with
federal laws regulating the export of, and applicable foreign government laws
regulating the import of, our products.  Although we have obtained approval to
export our NetSign and ProFile Manager products, the federal government may
rescind this approval at any time.  Additionally, we may apply for export
approval, on a specific criteria basis, for our future products.  We may not
receive approval to export any future products on a timely basis, on the basis
we request or at all.

OUR OPERATIONS COULD SUBJECT US TO TAXATION IN UNFORSEEN JURISDICTIONS.

     Many companies conducting electronic commerce do not collect sales or other
similar taxes with respect to shipments of goods into other states or foreign
countries.  It is possible that federal, state or foreign governments may seek
to impose sales taxes on companies that engage in electronic commerce.  Due to
the increasing popularity of the Internet, intranets and extranets, it is
possible that laws and regulations may be enacted covering issues such as user
privacy, pricing, content and quality of products and services.  Widespread
adoption of laws and regulations of this type or the imposition of sales or
other taxes on electronic commerce could slow substantially the growth of the
Internet, intranets and extranets, which could result in decreased demand for
our products and adversely affect our business.     

                                      -23-
<PAGE>
 
    
OUR QUARTERLY OPERATING RESULTS MAY FLUCTUATE SIGNIFICANTLY.

     Our quarterly operating results may fluctuate significantly as a result of
a variety of factors, many of which are outside our control. These factors
include:

     .    the short-term or long-term nature of customer commitments;

     .    the length of the sales and implementation cycle for our products and
          services;

     .    patterns of information technology spending by customers;

     .    the timing, size, mix and customer acceptance of our product and
          service product offerings and those of our competitors;

     .    the timing and magnitude of required capital expenditures;

     .    the need to use outside contractors to complete some assignments; and

     .    general economic conditions.

     Accordingly, comparisons of quarterly results may not be meaningful and
should not be relied upon, nor will they necessarily reflect on future
performance.  Because of the foregoing factors, it is likely that in some future
quarters our operating results will be below the expectations of public market
analysts and investors.  If this were to happen, the price of our common stock
would likely be adversely affected.

OUR EFFORTS TO EXPAND INTERNATIONAL OPERATIONS ARE SUBJECT TO A NUMBER OF RISKS.

     We are seeking to increase international sales which are not currently
material to our business.  While we believe our current products and services
are designed to meet the regulatory standards of foreign markets, our inability
to maintain or to obtain foreign regulatory approvals on a timely basis in the
future could adversely affect our business.  Additionally, our international
operations could be subject to a number of risks, any of which could adversely
affect our business, including:

     .    establishing or maintaining international distribution channels;
     .    increased collection risks;
     .    trade restrictions;
     .    export duties and tariffs; and
     .    uncertain political, regulatory and economic developments.

OUR ABILITY TO PRODUCE THE FORTE PKICARD ON A TIMELY AND COST-EFFECTIVE BASIS
DEPENDS ON THE AVAILABILITY OF A COMPUTER CHIP FROM ATMEL, WITH WHOM WE DO NOT
EXPECT TO MAINTAIN A SUPPLY AGREEMENT.

     Any inability to receive adequate supplies of Atmel Corporation's specially
designed Forte microprocessor would adversely affect our ability to complete and
sell the Forte PKIcard.  We do not anticipate maintaining a supply agreement
with Atmel Corporation for the Forte microprocessor.  If Atmel were unable to
deliver the Forte microprocessor for a lengthy period of time or terminated its
relationship with us, we would be unable to produce the Forte PKIcard until we
could design a replacement computer chip for the Forte microprocessor.  We
anticipate this would take substantial time and resources to complete.

AFTER THIS OFFERING, A SMALL NUMBER OF STOCKHOLDERS, INCLUDING OFFICERS AND
DIRECTORS, WILL HAVE THE ABILITY TO CONTROL STOCKHOLDER VOTES.

     Upon the closing of this offering, Kris Shah and members of his family,
William W. Davis, Sr. and Lillian A. Davis will beneficially own, in the
aggregate, approximately 66.8% of our outstanding common stock.  These
stockholders, if acting together, would have the ability to elect our directors
and to determine the outcome of corporate actions requiring stockholder
approval, irrespective of how other stockholders may vote.  This concentration
of ownership may also have the effect of delaying or preventing a change in
control.

A SIGNIFICANT PORTION OF THE PROCEEDS OF THIS OFFERING WILL BE USED TO REPAY
INDEBTEDNESS AND THUS WILL BE UNAVAILABLE TO FUND FUTURE GROWTH.

     We have allocated $12,500,000 (48.7%) of the net proceeds of this offering
to repay outstanding indebtedness, including approximately $6.2 million of
indebtedness assumed in connection with the acquisition of Pulsar. Consequently,
these funds will not be available to fund future growth. All of this
indebtedness is personally guaranteed by, and/or secured by pledges of assets
of, Kris Shah, William Davis or Lillian Davis. These persons will receive a
benefit from the release of these guarantees and security pledges.

THERE ARE LAWSUITS PENDING AGAINST PULSAR WHICH COULD ADVERSELY AFFECT OUR 
BUSINESS IF THEY ARE RESOLVED AGAINST PULSAR.

     Lawsuits are pending against Pulsar claiming (a) damages of approximately
$10.3 million resulting from Pulsar's alleged breach of a contract for
government contract bid preparation services and (b) unspecified damages
resulting from alleged race and age discrimination in connection with the
termination of a Pulsar employee. While Pulsar believes these lawsuits are
without merit, if these lawsuits were resolved against Pulsar, our business and
financial condition could be materially adversely affected. See "Business --
Legal Proceedings."

THERE HAS BEEN NO PRIOR PUBLIC MARKET FOR OUR COMMON STOCK AND THE OFFERING
PRICE HAS BEEN ARBITRARILY DETERMINED.

     Before this offering there has been no public market for our common stock.
There may not be an active trading market for our common stock after the
offering.  The initial public offering price has been determined by negotiations
between our management and the representatives of the underwriters and does not
necessarily reflect the assets, book value or potential earnings of our company
or any other recognized criteria of value.  Additionally, investors may not be
able to resell their shares at or above the initial public offering price.     

                                      -25-

OUR STOCK PRICE COULD BE EXTREMELY VOLATILE.
    
     The trading price of our common stock may be highly volatile as a result of
factors specific to us or applicable to our market and industry in general.
These factors, include:     

     .    variations in our annual or quarterly financial results or those of
          our competitors;
       
     .    changes by financial research analysts in their recommendations or
          estimates of our earnings;
       
     .    conditions in the economy in general or in the information technology
          service sector in particular;
       
     .    announcements of technological innovations or new products or services
          by us or our competitors; and
    
     .    unfavorable publicity or changes in applicable laws and regulations
          (or their judicial or administrative interpretations) affecting us or
          the information technology service sectors.     
    
     In addition, the stock market has recently been subject to extreme price
and volume fluctuations. This volatility has significantly affected the market
prices of securities issued by many companies for reasons unrelated to the
operating performance of these companies. In the past, following periods of
volatility in the market price of a company's securities, some companies have
been sued by their stockholders. If we were sued, it could result in substantial
costs and a diversion of management's attention and resources, which could
adversely affect our business.     
    
WE HAVE ANTI-TAKEOVER DEFENSES THAT COULD DELAY OR PREVENT AN ACQUISITION AND
COULD ADVERSELY AFFECT THE PRICE OF OUR COMMON STOCK.     
    
     Our certificate of incorporation and bylaws contain provisions that may
deter a takeover or a change in control not approved by our board of directors
or otherwise adversely affect the price of our common stock, including:     
    
     .    authority of our board of directors to issue common stock and
          preferred stock and to determine the price, rights, including voting
          rights, preferences, privileges and restrictions of each series of
          preferred stock, without any vote or action by our stockholders;     
       
     .    the existence of large amounts of authorized but unissued common stock
          and preferred stock;
       
     .    staggered, three-year terms for our board of directors;
       
     .    limitations on who may call special meetings of stockholders;

                                      -26-
<PAGE>
 
     .    prohibition of stockholders' action by written consent; and

     .    advance notice requirements for board of directors nominating and
          stockholder proposals.
    
     The rights and preferences of any series of preferred stock could include a
preference over our common stock on the distribution of the assets upon a
liquidation or sale of our company, preferential dividends, redemption rights,
the right to elect one or more directors and other voting rights.  The rights of
the holders of any series of preferred stock that may be issued in the future
may adversely affect the rights of the holders of our common stock.  In
addition, provisions of Delaware law may discourage, delay or prevent a change
in control or unsolicited acquisition proposals.

PURCHASERS IN THIS OFFERING WILL SUFFER IMMEDIATE AND SUBSTANTIAL DILUTION OF
THEIR INVESTMENT.

     Purchasers of common stock in this offering will pay a price per share
which substantially exceeds the per share value of our assets after subtracting
our liabilities. In addition, purchasers of common stock in this offering will
have contributed 48% of the aggregate price paid by all purchasers of our stock
but will own only 33% of the common stock outstanding after this offering.

THE NUMBER OF SHARES ELIGIBLE FOR FUTURE SALE AND THE EXISTENCE OF REGISTRATION
RIGHTS COULD DEPRESS THE MARKET FOR OUR COMMON STOCK.

     The possibility that a substantial number of additional shares of common
stock may become tradeable in the public market following this offering may
adversely affect prevailing market prices for our common stock and could impair
our ability to raise capital through the sale of existing securities.  An
aggregate of 3,870,693 of the 6,040,631 shares currently restricted from trading
in the public market will become eligible for sale 90 days following the date of
this prospectus, subject to agreements with BlueStone restricting their sale for
periods of at least six months.  We cannot predict the effect, if any, that
sales of these additional securities or the availability of these additional
securities for sale will have on the market prices prevailing from time to time.
In addition, the representatives of the underwriters have also been granted
registration rights commencing one year from the date of this prospectus
providing for the registration under the Securities Act of the securities
issuable upon exercise of the representatives' warrants.  The exercise of these
rights could result in substantial expense to us. Furthermore, if the
representatives exercise their registration rights, they will be unable to make
a market in our securities for up to nine days before the initial sales of the
warrants until the discontinuation of sales.  If the representatives cease
making a market, the market and market prices for the securities may be
adversely affected and the holders of these securities may be unable to sell
them.

                                USE OF PROCEEDS
    
     The net proceeds we will receive from the sale of common stock in this
offering are estimated to be approximately $25.7 million ($29.8 million if the
representatives' over-allotment option is exercised in full), assuming an
initial public offering price of $10.00 per share (the midpoint of the currently
anticipated range of the initial public offering price) and after deducting
underwriting discounts and estimated offering expenses.  We expect to use the
net proceeds approximately as follows:

REDUCTION OF DEBT

     We expect to use proceeds to reduce debt as follows:

     .    $5.9 million to repay BYL Bank Group for anticipated borrowings
          through the date of this prospectus. This debt bears interest at the
          annual rate of 6.6% and matures on February 28, 2000, except that it
          is required to be repaid upon a change of control of our wholly-owned
          subsidiary, Litronic Industries. It is guaranteed by Kris Shah, our
          chief executive officer and chairman of the board, and is secured by
          personal assets pledged by Mr. Shah.
       
     .    $4.2 million to repay in full the principal amount of notes to
          Wilmington Trust Company. The Wilmington Trust Company debt bears
          interest at the prime rate as in effect from time to time and matures
          in December 2002. The Wilmington Trust Company debt is personally
          guaranteed by William W. Davis, Sr., our president and chief operating
          officer, and Lillian A. Davis, a principal stockholder of our company,
          and is secured by property pledged by a family member of Mr. 
          Davis.     

                                      -29-
<PAGE>
 
    
     .    $1.3 million to IBM Global Finance Corporation (IGFC) to reduce the
          amount outstanding under an asset-based inventory and working capital
          financing agreement. The financing line bears interest at an annual
     .    rate of prime plus 2.375% and is guaranteed by Mr. Davis and Ms. Davis
          and is secured by assets pledged by Mr. Davis.

     .    $650,000 to pay IGFC under its forbearance agreement with Pulsar which
          becomes payable upon closing of this offering. The obligation under
          the forbearance agreement are guaranteed and are secured by Mr. Davis
          and Ms. Davis and secured by assets pledged by Mr. Davis.

     .    $450,000 to repay in full a line of credit from Fidelity Funding, Inc.
          The Fidelity Funding, Inc. debt currently bears interest at an annual
          rate of prime plus 1.5%, is due on February 28, 2000, and is
          personally guaranteed by Mr. Shah.     


SALES AND MARKETING

     We expect to use the proceeds allocated to sales and marketing as follows:
    
     .    to expand our sales and marketing efforts, primarily to commercial
          markets, including hiring approximately 20 additional sales and
          marketing personnel;
       
     .    to open additional sales and support offices;
       
     .    to expand our Internet and other advertising efforts;
       
     .    to improve our web site; and
       
     .    to expand strategic alliances.


PRODUCT DEVELOPMENT

     We expect to use the proceeds allocated to product development to pay our
estimated costs of software and product development, including compensation and
benefits payable to additional software and hardware engineers and developers.
Of the proceeds allocated to product development, $1.2 million represents funds
allocated to the development of Assure technology-based products.  If our bid
for the Assure technology is not the winning bid in its foreclosure sale, this
$1.2 million will be added to working capital.

WORKING CAPITAL AND GENERAL CORPORATE PURPOSES

     We may use a portion of the proceeds for potential acquisitions of
technologies, product lines and businesses and to upgrade our existing
management information systems and     

                                      -30-
<PAGE>
 
    
supporting information technology equipment. We currently have no commitments,
understandings or arrangements with respect to any future acquisitions.

     If the representatives of the underwriters exercise their over-allotment
option in full, we will realize additional net proceeds of approximately $4.1
million.  We would use these proceeds for working capital and general corporate
purposes.  Pending the uses described above, we intend to invest the net
proceeds of this offering in U.S. government securities, short-term certificates
of deposit or other short-term, investment grade, interest-bearing securities.

     The allocations described above represent our best estimate of the
anticipated use of the offering proceeds. Our estimate is based upon our
operating plans and our assumptions about research and development progress,
general economic conditions and industry factors. If any of these factors
change, we may find it necessary or advisable to reallocate our use of proceeds.

     In addition to the proceeds of this offering, we expect to obtain a new
$20.0 million revolving line of credit facility with Fidelity Funding, Inc. and
to borrow under this facility as needed to finance our operations and working
capital requirements. We have entered into a letter of intent with Fidelity
relating to this new facility and expect to enter into a definitive agreement
permitting us to borrow under this facility commencing with the closing of this
offering. The letter of intent contemplates a three-year term, subject to one-
year renewals at Fidelity's option, an annual interest rate of prime plus .625%
and a pledge of all our personal and real property as collateral.

     We believe that the net proceeds of this offering, together with
anticipated cash flow from operations, availability under our new $20.0 million
credit facility and existing cash and cash equivalents, will be sufficient to
satisfy our contemplated cash requirements for at least 12 months following the
closing of this offering, including planned capital expenditures of $1.0
million. We could be required to seek additional financing, however, if:

     .    our plans change due to changes in market conditions, competitive
          factors, progress of our research and development efforts or new
          opportunities that may become available in the future;
       
     .    our assumptions change or prove to be inaccurate; or
       
     .    the net proceeds of this offering or our cash flows prove to be
          insufficient to finance our growth strategy.     


                                DIVIDEND POLICY
    
          Before the date of this prospectus, Litronic Industries was an S
corporation for federal and California state income tax purposes. As an S
corporation, Litronic      

                                      -31-
<PAGE>
 
    
Industries made cash distributions of approximately $18.0 million to its
stockholders during the year ended December 31, 1997. We do not anticipate
paying cash dividends in the foreseeable future. We intend to retain future
earnings for the development and expansion of our business. The declaration and
payment of dividends or other distributions is currently prohibited by the terms
of financing agreements we have with our lenders and is likely to continue to be
restricted for the foreseeable future.     


                                    DILUTION
    
     The difference between the initial public offering price per share of
common stock and the net tangible book value per share of common stock after the
offering constitutes the dilution to new investors.  Our net tangible book value
per share is calculated by dividing the difference between our total tangible
assets and our total liabilities by the number of shares of our common stock
outstanding.

     At December 31, 1998, the net tangible book value (deficit) of Litronic was
$(4.2 million), or $(1.09) per share.  After giving retroactive effect to (a)
the Pulsar acquisition and (b) Litronic's receipt and anticipated application of
the net proceeds from the sale of the 3,000,000 shares of our common stock in
this offering, at an assumed price of $10.00 per share, Litronic's as adjusted
net tangible book value at December 31, 1998 would have been $11.1 million or
$1.23 per share.  This represents an immediate increase in net tangible book
value of $2.32 per share to existing stockholders and an immediate dilution of
$8.77 per share to new investors.

     The following table illustrates this per share dilution to new investors:

     The following table summarizes, on a pro forma basis, as of December 31,
1998, and giving retroactive effect to the Pulsar acquisition, the differences
between the number of shares of common stock purchased from us, the aggregate
consideration paid, and the average price per share paid by existing
stockholders and new investors purchasing common stock in this offering. In
summarizing this information, we have:     

    
     .    calculated the total consideration paid by existing stockholders based
          on the historical value of Litronic's common stock and the fair value
          of the common stock issued in connection with the Pulsar acquisition;
          and

     The table above assumes the representatives of the underwriters have not
exercised their over-allotment option.  If this option is exercised in full, the
new investors will have paid $34.5 million (based on an assumed offering price
of $10.00 per share) for 3,450,000 shares of common stock, representing
approximately 51.8% of the total consideration for 36.4% of the total number of
shares outstanding.  In making the computations in the table, we excluded:

     .    281,419 shares of common stock reserved for issuance upon the exercise
          of outstanding options under our 1998 stock option plan, at an
          exercise price of $.70 per share;

     .    600,000 shares of common stock reserved for issuance upon the exercise
          of options available for future grant under our 1999 stock option
          plan; and

     .    300,000 shares of common stock reserved for issuance upon the exercise
          of warrants to be issued to the representatives of the underwriters in
          connection with this offering.

the years in the four-year period ended December 31, 1997, derived from the
financial statements of Pulsar, which have been audited by Keller Bruner &
Company, L.L.C., independent certified public accountants. The selected

31, 1997 and 1998, and for each of the years in the three year period ended

     The selected data should be read in conjunction with the financial
statements of Pulsar for the three-year period ended December 31, 1998, the
related notes and the independent auditors' reports, which contain explanatory
paragraphs that state that Pulsar's recurring losses from operations, violation

the selected data do not include any adjustments that might result from the
outcome of this uncertainty.

*    The breakdown of revenue and cost of revenue between services and products
     is not available for the years ended December 31, 1994 and 1995 because,
     prior to 1996, Pulsar's accounting system did not track product and service
     revenue separately.  In 1996, Pulsar installed a new accounting system and
     has since been able to break out product and service revenue.

                           PRO FORMA FINANCIAL DATA

     The following pro forma financial data is based upon data derived from
Litronic's and Pulsar's historical consolidated financial statements and has
been prepared to illustrate the effects on this data of the Pulsar acquisition
and this offering. The Unaudited Pro Forma Statements of Operations for the year
ended December 31, 1998 gives effect to the acquisition and the closing of this
offering as if these transactions had occurred as of January 1, 1998. The
Unaudited Pro Forma Balance Sheet as of December 31, 1998 gives effect to the
acquisition and this offering as if these transactions had occurred as of
December 31, 1998. The Pulsar acquisition will become effective simultaneously
with, and as a condition to, the closing of this offering. The acquisition will
be recorded using the purchase method of accounting.

     The pro forma adjustments are based upon preliminary estimates, currently
available information and assumptions that management deems appropriate.  We
have assumed for the purpose of determining the purchase price of the Pulsar
acquisition that our common stock issued to the Pulsar stockholders is valued at
the initial public offering price.  The preliminary estimates regarding
allocation of the purchase price are subject to uncertainties, including, among
others, the final offering price per share and final determination of the fair
value of the net assets acquired.  In management's opinion, the preliminary
estimates regarding allocation of the purchase price of Pulsar are not expected
to differ materially from the final allocation.  The purchase price allocation
will be finalized after the closing of the acquisition.  The pro forma financial
data presented herein are not necessarily indicative of the results we would
have obtained had these events occurred at the beginning of the period, as
assumed, or of our future results as a combined entity.

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

     The following discussion should be read in conjunction with the Selected
Financial Data of Litronic and Pulsar, the Pro Forma Financial Data, and the
financial statements and related notes appearing elsewhere in this 
prospectus.     

GENERAL
    
     Litronic provides professional Internet data security services and develops
and markets software and microprocessor-based products needed to secure
electronic commerce and communications over the Internet and other
communications networks based on Internet protocols.  Litronic's primary
technology offerings use public key infrastructure, which is the standard
technology for securing Internet-based commerce and communications.

     Prior to 1990, Litronic was solely a provider of electronic interconnect
products to government and commercial entities.  In 1990, Litronic formed its
data security division, which forms the basis of its operations today.  The data
security division was engaged primarily in research and development until 1993
when it began to generate meaningful revenue.  In September 1997, Litronic sold
its Intercon division, which consisted of the assets relating to its
interconnect operations, for cash to Allied Signal Inc., a non-related,
publicly-traded company. The gain on sale was $15 million, net of tax expense of
$241,000.  In addition to the cash proceeds received, the sales agreement
provided for Litronic's right to receive a contingent purchase price.  Effective
November 30, 1997, this right was distributed pro rata to the shareholders of
Litronic. Except for senior management, these operations were operated
independently from Litronic's data security operations. Litronic charged direct
costs to the division incurring them. Indirect or shared costs, such as senior
management compensation and benefits, rent, utilities and costs of tax, legal
and other advisory services, were allocated on the basis of actual usage and
head count. Litronic's historical consolidated financial statements have been
restated to reflect the sale of the Intercon division as discontinued
operations. See Note 2 to Notes to Consolidated Financial Statements of
Litronic.

     Upon the closing of this offering, Litronic is acquiring Pulsar, a provider
of network-based information technology consulting services to commercial
accounts and federal, state and local government agencies, in exchange for
2,169,938 shares of our common stock valued at $10.00 per share, the anticipated
initial public offering price.  In addition to its consulting services, Pulsar
also has an established product reseller business, which focuses on resales to
government agencies, large corporate accounts and state and local 
governments.

PRO FORMA INFORMATION AND FUTURE TRENDS
    
     Following this offering, we intend to roll out our enterprise-wide data
security products to Pulsar's significant existing client base.  We believe that
Pulsar's custom-designed secure PCs will provide us with another type of data
security product offering, thereby broadening the scope of our offerings and
enabling us to provide our customers with a comprehensive data security
solution.  Our strategy also involves continuing Pulsar's recent shift in
product reselling focus to higher margin products, expanding Pulsar's
professional service offerings and increasing sales of Pulsar's products and
professional services to commercial customers and state and local governments.
We also intend to leverage Pulsar's direct sales force, distribution channels
and partners to expand our marketing of our Internet data security products.

   REVENUE

   During the year ended December 31, 1998, sales of Internet data security
products, including NetSign, Pro File Manager and CryptOS, accounted for 6% of
our revenue on a pro forma combined basis.

   We are currently experiencing increased demand for our Internet data security
products, including NetSign, ProFile Manager and CryptOS, from commercial
customers.  Our recently released Internet-related products such as NetSign,
NetSign Pro, CipherServer, and developer toolkits such as CryptOS SDK, have also
experienced favorable market acceptance. We expect to continue to experience
significant increases in sales of these products as a result of the expected
continued growth in electronic commerce and communications over the Internet and
our plan to roll out our data security products to Pulsar's existing and
significant client base.

   During the year ended December 31, 1998, on a pro forma combined basis,
product reselling accounted for 89% of our revenue and license and service
revenue accounted for 6% of our revenue.  As we expand our professional service
offerings and grow our sales of Internet data security products, we expect
license and service revenue to increase as a percentage of revenue and product
reselling to account for a decreasing portion of our revenue.

   On a pro forma combined basis, one of our customers, the U.S. Immigration and
Naturalization Service, accounted for more than 10% of revenue (21%) during the
year ended December 31, 1998.  Sales to U.S. government agencies accounted for
approximately  90% of our pro forma combined revenue for the year ended December
31, 1998.     

                                      -46-

   GROSS MARGINS
    
   During the year ended December 31, 1998, Litronic's data security products
had gross margins of 46% and Pulsar's product reselling activities had gross
margins of 7%. Pulsar recently shifted its product reselling focus toward higher
margin computer and network security products, including intrusion detection
software and firewalls. We intend to continue to focus our product reselling
efforts toward these products. As a result, we expect product reselling gross
margin to increase as a percentage of corresponding revenue. Our license and
service revenue has relatively high gross margins with a gross margin of 48% for
the year ended December 31, 1998 on a pro forma combined basis. Because we
expect our higher gross margin sources of revenue to increase as a percentage of
revenue and our gross margin from product reselling to increase, we expect our
gross margin to increase as a percentage of total revenue.

   COST CUTTING MEASURES

   Pulsar has taken several cost cutting measures since the beginning of 1998
which have significantly reduced the expenses associated with selling, general
and administrative activities, including an overall reduction of staff from 75
persons at December 31, 1997 to 44 persons at April 1, 1999, enhanced credit
procedures and reduced rent expense. As a combined entity, we expect to further
decrease our rent expense through the consolidation of Litronic's Washington,
D.C. area offices into Pulsar's offices in Lanham, Maryland.

   FOCUSED MARKETING EFFORTS

   We have recently begun to focus our marketing efforts on commercial
customers.  The commercial markets for PKI security products are expected to be
intensely competitive.  In addition, as we intensify our focus on the commercial
markets and expand the marketing of our Internet data security products, we
anticipate increasing expenditures for sales and marketing, particularly
expenses associated with

   .      opening additional marketing channel support offices;
   .      adding commercial sales personnel to focus on sales to commercial
          markets; and
   .      continually introducing and refining products in response to market
          demands.

   Our sales and marketing expenses are generally incurred in advance of
associated revenue and we expect these expenses to increase in the near term
both as a percentage of revenue as well as in amount. These measures could
adversely affect our operating income.     

                                      -47-
<PAGE>
 
    
   As a result of the cost cutting measures and focused marketing efforts
described above we expect a net reduction in selling, general and administrative
expenses.

   RESEARCH AND DEVELOPMENT

   In an effort to increase our research and development activities, we have
allocated $6.2 million of the net proceeds of this offering to research and
development activities for the next 12 months. We expect expenses related to
research and development to increase significantly as a consequence of our
increased focus on these activities.

   INTANGIBLE ASSETS

   The Pulsar acquisition will result in a significant increase in our
intangible assets. Approximately $32.2 million, or 53%, of our pro forma
combined, as adjusted, assets as of December 31, 1998, consisted of intangible
assets arising from the acquisition. This amount represents goodwill and other
intangibles, which will be amortized over 15 years and represents the excess of
the aggregate purchase price paid in connection with the acquisition over the
fair value of net assets acquired. The amount of goodwill and other intangibles
amortized in a particular period constitutes a non-cash expense, which is not
tax deductible, that reduces our net earnings or increases our net loss.

RESULTS OF OPERATIONS--COMPARISON OF YEARS ENDED DECEMBER 31, 1996, 1997 AND
1998

   LITRONIC

   TOTAL REVENUE. Total revenue increased 8% from $9.4 million during the year
ended December 31, 1996 to $10.2 million during the year ended December 31, 1997
and decreased 35% from 1997 to $6.7 million during the year ended December 31,
1998. The increase from 1996 to 1997 was primarily attributable to increased
sales of the ARGUS 300 products to the U.S. Army Corps of Engineers. The
decrease from 1997 to 1998 was primarily attributable to the decreased sales of
the ARGUS 300 products, as described below.

   During the year ended December 31, 1996, Litronic derived 39%, 29% and 18% of
its revenue from sales to Lockheed Martin Corporation, U.S. Army Corps of
Engineers and the National Security Agency. During the year ended December 31,
1997, Litronic derived 45%, 20%, and 19% of its revenue from sales to U.S. Army
Corps of Engineers, Lockheed Martin Corporation and the National Security
Agency. During the year ended December 31, 1998, Litronic derived 44%, 20% and
17% of its revenue from sales to Lockheed Martin Corporation, the National
Security Agency and the U.S. Army Corps of Engineers. Sales to federal
government agencies accounted for approximately 84% and 81% of Litronic's sales
during the years ended December 31, 1997 and 1998.     

                                      -48-
<PAGE>
 
    
   PRODUCT REVENUE. Product revenue increased 10% from $7.9 million in the year
ended December 31, 1996 to $8.6 million in the year ended December 31, 1997 and
decreased 40% from 1997 to $5.2 million in the year ended December 31, 1998. The
increase from 1996 to 1997 was primarily attributable to increased sales of our
Argus 300 products to the U S. Army Corps of Engineers. The decrease from 1997
to 1998 is primarily attributable to reduced sales of our ARGUS 300 products to
the U.S. Army Corps of Engineers as a result of the substantial completion of
the Corp of Engineers Financial Management Services contract (the CEFMS
contract). We expect that sales of the ARGUS 300 product under the CEFMS
contract will continue to diminish; however, we expect significant additional
sales of the ARGUS 300 and other products to the U.S. Army Corps of Engineers as
a result of its recently commenced program to upgrade its information technology
systems periodically. Based on our experience with the U.S. Army Corps of
Engineers, we expect to participate in the program through sales of the ARGUS
300 and other products. The CEFMS contract with the U.S. Army Corps of Engineers
expired September 30, 1998. The Defense Messaging System contract expires in
November 1999, but it may be renewed by Lockheed Martin for up to four one-year
periods.

   LICENSE AND SERVICE REVENUE. License and service revenue was $1.5 million
during the years ended December 31, 1996 and 1997 and declined from 1997 by 7%
to $1.4 million for the year ended December 31, 1998. The decline from 1997 to
1998 was attributable primarily to reduced service revenue from the National
Security Agency as a result of its determination that it will no longer pay for
Litronic-provided support services for the Defense Messaging System and the
subsequent decline in support requests from users of Litronic's support
services. Also included in license and service revenue for the year ended
December 31, 1998 is $398,000 of reimbursements related to the Forte project
which Litronic received for its research and development efforts.

   TOTAL GROSS MARGIN. Gross margin increased as a percentage of revenue from
50% during the year ended December 31, 1996 to 62% during the year ended
December 31, 1997 and decreased as a percentage of revenue to 43% during the
year ended December 31, 1998. The increase from 1996 to 1997 was due primarily
to a change in product mix comprised of increased sales of the ARGUS 300
products to the U.S. Army Corps of Engineers and sales of higher margin software
products. The decline from 1997 to 1998 is primarily attributable to reduced
product sales as described below.

   PRODUCT GROSS MARGIN. Product gross margins increased as a percentage of net
product revenue from 48% during the year ended December 31, 1996 to 63% during
the year ended December 31, 1997 and decreased to 46% during the year ended
December 31, 1998. The increase from 1996 to 1997 resulted primarily from
increased sales of ARGUS data encryption products to the U.S. Army Corps of
Engineers. The decrease from 1997 to 1998 is primarily attributable to reduced
sales under the CEFMS contract and sales of low margin pass-through products to
the National Security Agency.

   LICENSE AND SERVICE GROSS MARGIN. License and service gross margin decreased
as a percentage of its revenue from 62% during the year ended December 31, 1996
to 58% during the year ended December 31, 1997 and decreased from 1997 to 34%
during the year     

                                      -49-
<PAGE>
 
    
ended December 31, 1998. The decrease from 1996 to 1997 was due to additional
head count and higher per employee costs. The decrease from 1997 to 1998
resulted primarily from higher compensation costs associated with the reduction
of support services revenue under the Defense Messaging System contract. All 
costs relating to the Forte project are included in research and development 
expenses during the year ended December 31, 1998.

   SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. Selling, general and
administrative expenses increased 70% from $2.1 million during the year ended
December 31, 1996 to $3.5 million during the year ended December 31, 1997 and
decreased 25% from 1997 to $2.6 million during the year ended December 31, 1998.
As a percentage of revenue, selling, general and administrative expenses
increased from 22% during the year ended December 31, 1996 to 34% during the
year ended December 31, 1997 and increased from 1997 to 40% during the year
ended December 31, 1998. Selling, general and administrative expenses during
1997 were higher due to bonuses paid to shareholder employees following the sale
of the Intercon division. In addition, selling, general and administrative
expenses increased as a percentage of revenue due to increased staffing to
support the anticipated expansion of Litronic's business.

   RESEARCH AND DEVELOPMENT EXPENSES. Research and development expenses
increased 62% from $725,000 during the year ended December 31, 1996 to $1.2
million during the year ended December 31, 1997 and increased 14% from 1997 to
$1.3 million during the year ended December 31, 1998. The increases from 1996 to
1998 were primarily attributable to increased costs associated with increased
new product development, including expenses associated with the development
efforts of the Forte microprocessor, which we are designing in conjunction with
Atmel Corporation to be embedded in our Forte PKIcard. As a percentage of
revenue, research and development expenses increased from 8% during the year
ended December 31, 1996 to 12% during the year ended December 31, 1997 and
increased from 1997 to 20% during the year ended December 31, 1998. These
increases reflected our continued investment in research and development of
future products and services coupled with the reduction in revenue in 1998
described above.

   INTEREST EXPENSE, NET. Interest expense, net, increased by 121% from $19,000
during the year ended December 31, 1996 to $42,000 during the year ended
December 31, 1997 and increased almost tenfold from 1997 to $418,000 during the
year ended December 31, 1998. The increases in interest expense from 1996 to
1998 were attributable to increased levels of borrowings required for
operations.

   INCOME TAXES. Prior to this offering, Litronic elected to be treated as an S
corporation under the provisions of Section 1362 of the Internal Revenue Code of
1986 and used the accrual basis of reporting for income tax purposes.
Accordingly, Litronic did not provide for federal income taxes at the corporate
level. Litronic was subject to state taxes on earnings before taxes. The
provision for state income taxes was $29,000 and $22,000 for the years ended
December 31, 1996 and 1997. For the year ended December 31, 1998 Litronic had 
a     

                                      -50-
<PAGE>
 
    
benefit of $95,000 as a result of losses from continuing operations before
income taxes of $1.5 million.

   BACKLOG. At December 31, 1998, Litronic had total backlog of $717,000,
including $109,000 attributable to Lockheed Martin Corporation and $596,000
attributable to the National Security Agency. Backlog represents signed purchase
orders received but not filled and, in the case of the $596,000 attributable to
the National Security Agency, reimbursements for funding of future research and
development expense. At December 31, 1997, we had total backlog of $1.1 million,
including $466,000 attributable to Lockheed Martin Corporation and $578,000
attributable to the National Security Agency.

   PULSAR

   TOTAL REVENUE. Total revenue decreased 9%, from $166.0 million during the
year ended December 31, 1996 to $151.5 million during the year ended December
31, 1997 and decreased 47% from 1997 to $80.5 million during the year ended
December 31, 1998.

   During the years ended December 31, 1997 and 1998, Pulsar derived 23% and 11%
of its revenue from sales to the U.S. Immigration and Naturalization Service.
Total revenue to federal government agencies decreased 10% from $101.0 million
during the year ended December 31, 1996 to $91.4 million for the year ended
December 31, 1997 and declined 21% from 1997 to $72.5 million during the year
ended December 31, 1998. The decrease is attributable primarily to a decrease in
Pulsar's sales to the U.S. government under its Section 8(a) contracts,
partially offset by an increase in General Services Administration schedule
revenue and National Institutes of Health contract revenue.

   PRODUCT REVENUE. Product revenue declined 8%, from $155.7 million during the
year ended December 31, 1996 to $142.7 million during the year ended December
31, 1997, and declined 46% from 1997 to $77.2 million during the year ended
December 31, 1998. This decrease was primarily attributable to the following
factors:

   .   In 1997, Pulsar made a strategic decision to eliminate its high volume,
       low margin Federal Systems Integration (FSI) program activities, which
       accounted for 23% of its revenue during 1996, 24% of its revenue during
       1997 and 4% of its revenue during 1998. Sales under the FSI program were
       phased out during this period due to the diminishing margins produced by
       these sales. FSI revenue decreased 4% from $38.1 million in the year
       ended December 31, 1996 to $36.7 million in the year ended December 31,
       1997 and decreased 92% from 1997 to $3.2 million in the year ended
       December 31, 1998.

   .   Pulsar voluntarily withdrew from the Section 8(a) program in June 1997
       in anticipation of its scheduled graduation from the program in November
       1997. Section 8(a) contract revenue decreased by 71% from $50.1 million
     

                                      -51-
<PAGE>
 
    
       during the year ended December 31, 1996 to $14.3 million during the year
       ended December 31, 1997 and decreased 78% to $3.1 million during the year
       ended December 31, 1998.

   .   Commercial, state and local government revenue decreased by 8% from $24.8
       million during the year ended December 31, 1996 to $22.9 million during
       the year ended December 31, 1997, primarily due to a sales staff focus on
       FSI program revenues, and decreased 83% to $3.9 million during the year
       ended December 31, 1998 primarily due to the loss of a contract with
       Montgomery County, Maryland and the closing of Pulsar's Atlanta sales
       office.

   .   The reductions in revenue were partially offset by an increase in GSA
       schedule revenue commencing in 1996 and NIH revenue commencing in 1998.
       This revenue increased 61%, from $42.7 million during the year ended
       December 31, 1996 to $68.8 million during the year ended December 31,
       1997, and declined 3% from 1997 to $67.0 million during the year ended
       December 31, 1998. The overall increase in GSA and NIH contract revenue
       was primarily due to Pulsar's shift in sales focus in response to the
       Federal Streamline Act of 1996, which encourages all agencies to use the
       GSA or the NIH vehicle to procure products and services in support of
       information technology requirements in lieu of traditional time-
       restrictive contracting methods. The decrease in GSA revenue from 1997 to
       1998 was due in part to the government's reallocation of budget dollars
       from hardware and software procurements toward resolving year 2000
       issues.

   SERVICE REVENUE. Service revenue declined by 14%, from $10.3 million during
the year ended December 31, 1996 to $8.8 million during the year ended December
31, 1997 and declined 62% from 1997 to $3.4 million during the year ended
December 31, 1998. The decrease from 1996 to 1997 was attributable primarily to
the completion of a contract with Samsung Electronics. The decrease from 1997 to
1998 was attributable primarily to a reduction in service revenue from expiring
Section 8(a) contracts with the U.S. Department of Education and the Naval
Research Lab contract.

   TOTAL GROSS MARGINS. Pulsar's gross margin decreased as a percentage of
revenue from 10% during the year ended December 31, 1996 to 6% during the year
ended December 31, 1997 and increased from 1997 to 9% during the year ended
December 31, 1998. The gross margin declined from $16.6 million for the year
ended December 31, 1996 to $9.3 million for the year ended December 31, 1997 and
declined from 1997 to $7.2 million for the year ended December 31, 1998. The
overall decrease from 1996 to 1997 was attributable primarily to the reduction
in total revenue combined with a decrease in gross margin percentage. The
decrease from 1997 to 1998 was attributable only to a reduction in total
revenue.     

                                      -52-
<PAGE>
 
    
   PRODUCT GROSS MARGIN. Product gross margins declined as a percentage of
revenue from 7% during the year ended December 31, 1996 to 3% during the year
ended December 31, 1997 and increased from 1997 to 7% during the year ended
December 31, 1998. The decrease in product margins from 1996 to 1997 was
attributable to industry competition and write-off of obsolete inventory.
Consistent with Pulsar's business plan, the increase from 1997 to 1998 is
attributable primarily to reduced FSI sales, which are lower margin product, and
Pulsar's successful bidding for higher margin product contracts, partially
offset by the write-off of obsolete inventory.

   SERVICE GROSS MARGIN. Service gross margins remained unchanged at 53% during
the years ended December 31, 1996 and 1997 and increased slightly from 1997 to
54% during the year ended December 31, 1998.

   SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. Selling, general and
administrative expenses increased 27% from $13.5 million during the year ended
December 31, 1996 to $17.2 million during the year ended December 31, 1997 and
decreased 27% from 1997 to $12.5 million during the year ended December 31,
1998. The increase from 1996 to 1997 was attributable primarily to bad debt
expenses associated with accounts receivables and notes receivables. The
decrease from 1997 to 1998 reflects a reduction in the total amount of bad debt
expense and a reduction in administrative and sales staffing. Selling, general
and administrative expenses increased as a percentage of revenue from 8% during
the year ended December 31, 1996 to 11% during the year ended December 31, 1997
and increased from 1997 to 16% during the year ended December 31, 1998.

   BAD DEBT EXPENSE AND MEASURES DESIGNED TO REDUCE BAD DEBTS. Bad debt write-
offs increased from $403,000 during the year ended December 31, 1996 to $5.3
million during the year ended December 31, 1997 and decreased from 1997 to $3.4
million during the year ended December 31, 1998. Bad debt expense in 1997 was
primarily attributable to extending credit to commercial clients who did not
meet their obligations ($3.9 million), commercial loans outside of the normal
course of business that were deemed uncollectible ($702,000), and notes
receivable and related accrued interest to related parties that were deemed
uncollectible ($682,000). Bad debt expense in 1998 was incurred from commercial
clients who did not meet their obligations ($1.8 million) and rebate receivables
that expired because they were incomplete or not collected on a timely basis
($1.6 million). Pulsar has implemented procedures to reduce the exposure to
commercial bad debts, including:

   .      performing thorough credit reviews on all new and existing non-
          government customers, including verifying references and analyzing
          customer's Dun and Bradstreet reports before extending credit;

   .      changing its customer profile by significantly reducing FSI reseller
          clients from the federal government to Fortune 500 clients, thus
          reducing credit risk;

   .      implementing a tickler system to ensure that rebates are filed in a
          timely manner; and     

                                      -53-
<PAGE>
 
    
   .      establishing a collections staff to follow-up on payments related to
          rebates.

   COST CUTTING MEASURES DESIGNED TO REDUCE SELLING, GENERAL AND ADMINISTRATIVE
EXPENSES. In an effort to reduce selling, general and administrative expenses in
future periods, Pulsar has taken significant cost cutting measures, including:

   .      automating administrative job functions through business process
          reengineering and other reductions, thus reducing head count by 31
          positions from January 30, 1998 to April 1, 1999; and

   .      relocating to less expensive office space beginning October 1, 1998,
          thus decreasing monthly rent expense from $45,000 to $11,500.

   INTEREST EXPENSE. Interest expense increased by 2%, from $3.6 million during
the year ended December 31, 1996 to $3.6 million during the year ended December
31, 1997, and decreased by 42% from 1997 to $2.1 million during the year ended
December 31, 1998. Pulsar's average daily borrowings decreased during 1996, but
additional interest expense was recognized due to a new agreement Pulsar entered
into with its creditor, IGFC. Interest expense decreased in 1998 due to a
significant decrease in borrowings.

   INTEREST INCOME. Interest income decreased by 28%, from $639,000 during the
year ended December 31, 1996 to $457,000 during the year ended December 31, 1997
and decreased by 87% to $61,000 during the year ended December 31, 1998. These
decreases are attributable primarily to a reduction in the outstanding notes
receivable balances. Also, during 1998, Pulsar did not recognize interest income
on the related party notes receivable.

LIQUIDITY AND CAPITAL RESOURCES

   On a pro forma combined, as adjusted, basis, we had working capital of $10.0
million as of December 31, 1998.

   We have entered into a letter of intent with Fidelity Funding relating to a
new $20.0 million secured revolving line of credit facility and expect to enter
into a definitive agreement permitting us to borrow under this facility
commencing upon the closing of this offering. The letter of intent contemplates:

   .      a three-year term, subject to one-year renewals at the lender's
          option;

   .      an annual interest rate of prime plus .625%;

   .      a pledge of all of our personal and real property as collateral; and

   .      a cap on our borrowings equal to 85% of our accounts receivable plus
          the lesser of (a) 50% or (b) $1.0 million of our on-hand 
          inventory.     

                                      -54-
<PAGE>
 
    
   We believe that the net proceeds of this offering, together with availability
under our new $20.0 million revolving line of credit and existing cash and cash
equivalents, will be sufficient to satisfy our contemplated cash requirements
for at least 12 months following the closing of this offering, including planned
capital expenditures of approximately $1.0 million. We could be required to seek
additional financing if:

   .      our plans change due to changes in market conditions, competitive
          factors, progress of our research and development efforts or new
          opportunities that may become available in the future;

   .      our assumptions change or prove to be inaccurate; or

   .      the net proceeds of this offering or our cash flows prove to be
          insufficient to finance our growth strategy.


   LITRONIC

   Historically, Litronic's cash requirements have been financed through a
combination of cash flow from operations, except in the year ended December 31,
1998, bank financing and loans from its principal shareholders and affiliates.
Some of Litronic's borrowings contain covenants and restrictions, including
maintenance of minimum tangible net worth and working capital, and they prohibit
the payment of dividends. Litronic was in compliance with or had received
waivers for these covenants as of December 31, 1998 and March 31, 1999.

   During the year ended December 31, 1998, cash used in operations for Litronic
was $1.7 million, primarily due to a net loss of $1.4 million, a decrease in
accrued liabilities of $465,000, primarily due to the payment of accrued
bonuses, and an increase in other current assets of $249,000. These were
partially offset by a decrease in accounts receivable of $256,000 due to
improved collections in the latter part of 1998.

   During the year ended December 31, 1998, cash provided by financing
activities was $2.3 million, consisting primarily of borrowings of $6.5 million
under the revolving note payable to the bank and $5.2 million under the long-
term notes payable, partially offset by repayments of $3.5 million under a
related party note payable and $6.5 million under the revolving note payable to
a bank.

   Litronic's capital expenditures, including computer equipment, test equipment
and furniture and fixtures, were $118,000 during the year ended December 31,
1998. Litronic's capital expenditures were funded through cash generated from
operations and through its secured revolving credit line and borrowing from its
principal shareholders.

   PULSAR

   Pulsar's capital requirements have been and will continue to be significant.
To date, its cash requirements have exceeded its cash flow from operations.
Pulsar historically has satisfied cash requirements through borrowings. Pulsar's
financial statements include an explanatory paragraph in the independent
auditors' report that states that Pulsar's losses from operations, violation of
debt covenants and net capital deficiency raise substantial doubt about Pulsar's
ability to continue as a going concern. The debt covenants violated by Pulsar
were contained in its inventory and working capital financing agreement with
IGFC and in a series of subsequent forbearance agreements. These covenants
required Pulsar to maintain at various times financial ratios of annualized
revenue to working capital, net profit after tax to revenue and total
liabilities to tangible net worth. Pulsar has received a forbearance from IGFC
through the closing of this offering and expects to repay IGFC in full following
the closing of this offering.

   Total cash used for the year ended December 31, 1998 was $1.9 million.
Pulsar's cash provided from operations for the year ended December 31, 1998, was
$18.5 million. This primarily resulted from collections of accounts receivable
of $17.7 million, reduction of inventory of $1.6 million and an increase in
accounts payable of $2.6 million, offset by a net loss of $7.4 million,
including a non-cash bad debt expense of $3.4 million.

   Cash used in financing activities for the year ended December 31, 1998, was
$21.5 million, resulting primarily from $18.7 million in payments made to
decrease indebtedness outstanding under its financing arrangement with IGFC, a
portion of which was funded by borrowings of $1.5 million against the cash
surrender value of life insurance policies.

   Pulsar's capital expenditures, including computer equipment, warehouse
equipment, and furniture and fixtures, were $58,000 for the year ended December
31, 1998. Pulsar has notes receivable from related parties of approximately
$1,198,000 as of December 31, 1998 which are classified as a component of
stockholders' equity and have been fully reserved. Proceeds from loans from cash
surrender value of life insurance net of premium payments were $1.2 million.
Accounts payable of $5.9 million were converted to notes payable during 1998.

   Pulsar funded its operations during the year ended December 31, 1998 through
its financing agreement with IGFC. Under this agreement, Pulsar purchases
hardware and software from authorized suppliers and finances the purchases
through IGFC. The agreement provides for an initial credit line up to $18
million, which has been increased and decreased over time through amendments to
the forbearance agreement, based on Pulsar's hardware and software procurement
requirements financed through the line of credit, and as a result of defaults
that have occurred related to the forbearance agreements. As of March 31, 1999,
the maximum amount available under the line of credit was $9.0 million. The line
of credit allows Pulsar to finance up to 85% of its eligible accounts receivable
     

                                      -56-
<PAGE>
 
    
and 100% of the value of its on-hand inventory. The credit line is secured by
substantially all assets of Pulsar and is personally guaranteed by William W.
Davis, Sr. and Lillian A. Davis.

   IGFC has agreed to forbear Pulsar's violations of financial covenants in the
IGFC financing agreement in exchange for Pulsar's agreement to pay to IGFC, on
or before October 1999, either (a) warrants to purchase for a nominal amount a
fully diluted 4% ownership interest in Pulsar or (b) the lesser of:

   .   $650,000,

   .   4% of the sale price upon the sale of all or substantially all of
       Pulsar's assets, or

   .   a pro rata share of $650,000 upon the sale of less than substantially all
       of Pulsar's assets.

We intend to satisfy this obligation to IGFC by paying $650,000 to it upon the
closing of this offering.

     Pulsar has the following additional amounts due within the next twelve
months:

     .    Nine promissory notes payable to various vendors, which accrue
          interest ranging from 10% to 12% and have an aggregate principal
          balance of $3.4 million as of March 31, 1999. Balloon payments in the
          aggregate amount of $1.9 million are due in May 1999 and the balance
          is due by November 1999;

     .    total payments of $608,000 are due in May 1999 under negotiated payout
          agreements with ten accounts payable vendors.

Additionally, Pulsar has approximately $1.2 million of accounts payable balances
which are more than 90 days overdue. We expect to use our newly acquired line of
credit and cash from operations to fund these obligations to the extent we are
not able to negotiate extended payment arrangements.

     We have allocated $12.5 million of the net proceeds of this offering to
repay outstanding indebtedness, including $6.2 million of indebtedness assumed
in the Pulsar acquisition.  All of the indebtedness being repaid is required to
be paid upon the closing of this offering, as a result of change of control
provisions or to effect the release of personal guarantees.

YEAR 2000 ISSUES
    
     An issue affecting us and others is the inability of many computer systems
and applications to process the year 2000 date change, the date 9/9/99 and the
leap year 2000.  Many currently installed computer systems and software
applications are coded to accept only two digit entries in the date code field.
These date code fields will need to accept entries to distinguish 21st century
dates from 20th century dates.  The inability to recognize or properly treat the
year 2000 issue may cause Litronic's systems and applications to process
critical financial and operational information incorrectly.

     We have established a committee to determine the extent to which we may be
vulnerable to the year 2000 issue.  The committee is responsible for the ongoing
assessment, renovation of, testing, and certification of all business-critical
infrastructure systems and applications software. In the process of its
evaluation of the year 2000 issue, the committee has developed potential
business disruption scenarios and is developing a contingency plan, which we
anticipate will be completed by July 1999.  The costs incurred to date related
to the year 2000 issue have related primarily to time spent by employees in year
2000 compliance matters and have not been significant.  We do not believe future
costs will be significant.  The following is a description of how we have
categorized and are addressing the year 2000 issue.     

     INTERNAL SYSTEMS
    
     We have evaluated our internal computer systems in an effort to determine
the actions, if any, necessary to make them year 2000 compliant.  Our evaluation
has involved testing our systems to ensure that they are year 2000 compliant.
Based on its present review of our systems, the committee has determined that we
do not have a high risk of computer-related internal systems problems from the
year 2000 issue.     

     EMBEDDED SYSTEMS
    
     We also recognize that there are risks with respect to embedded systems
that are not necessarily part of our information technology systems but contain
microprocessor chips which may not function properly with the change of date to
the year 2000.  The majority of the embedded systems on which we rely in our
day-to-day operations are owned and managed by the lessors of the buildings in
which our offices are located, or by agents of these lessors.  We have received
letters from our lessors and, as applicable, their agents indicating the year
2000 compliance of the embedded systems.  Based upon these responses we do not
believe there are any year 2000 compliance issues with our embedded systems.

     Because we believe that our information technology and embedded systems
will be substantially year 2000 compliant in advance of the year 2000 date
change, we have no contingency plan to address non-compliance.  We expect that,
as we complete testing of      

                                      -58-
<PAGE>
 
    
information technology and embedded systems, we will develop contingency plans
if we determine that any business critical systems will not be year 2000
compliant.    

     OUTSIDE VENDORS AND CUSTOMERS

     Disruptions with respect to the computer systems of vendors or customers,
which are outside our control, could impair our ability to obtain services or
conduct business with our customers.  Disruptions of our utilities or
telecommunications systems could have a material adverse effect upon our
financial condition and results of operations.  We believe that no other
providers are material to our business.  Disruptions of customers' computer
systems could interfere with customers' ability to make timely payments on
accounts, could disrupt our customers' ability to manage the installation
process of our products, which could adversely affect our ability to reach our
milestones, and thus to recognize revenue, and could disrupt other
administrative activities.
    
     The committee has sent year 2000 issue questionnaires to our significant
vendors, suppliers and customers. Although the responses we have received do not
indicate any significant year 2000 issues, we do not have any assurances that
all of our significant vendors, suppliers and customers will take the necessary
steps to ensure that their respective systems will be protected against the year
2000 issue or that even if such steps are taken, they will be successful.  As we
continue to assess the risk of our significant vendors', customers' and
suppliers' systems, we will develop and implement, if necessary, curative plans
and contingency plans to address any year 2000 compliance issues.     

     OUR PRODUCTS
    
     We have determined that our products, to the extent that underlying
hardware platforms, operating systems and databases will accommodate the year
2000 date change, are year 2000 compliant and will accommodate the year 2000
date change.

     We anticipate that virtually all of our customers and potential customers
will be required to evaluate their information technology systems with respect
to the year 2000 date change and that some of our customers and potential
customers may incur material costs in connection with this evaluation and any
necessary repairs and replacements.  Customers and potential customers may be
required to devote material portions of their information technology budgets to
these evaluations, repairs and replacements, which could materially reduce their
other information technology purchases in 1999, including their purchases of
Litronic's products, particularly as the year 2000 date change draws closer.  We
do not have any information as to the degree to which this issue will affect our
customers or potential customers.

     SUMMARY
    
     There can be no assurance that any year 2000 issue-related precautions with
respect to our internal information technology systems, embedded systems or our
products will eliminate the numerous and varied risks associated with the year
2000 date change.  Further, there is a risk that we will be adversely affected
by the year 2000 issue or related difficulties encountered by vendors or
customers or by any downturn in information technology purchases or in the
economy in general as the year 2000 date change draws nearer.  Any of these
risks could adversely affect our business.

     Management believes that the most likely worst case scenario related to the
year 2000 issues that we may experience would be either an inability to obtain
inventory components from suppliers or delays in receiving orders or payments
from customers due to year 2000 problems experienced by these third parties.
These events, if experienced, could have a material adverse effect on our
business, results of operations, financial condition and/or liquidity.     

FLUCTUATIONS IN QUARTERLY OPERATING RESULTS
    
     Our quarterly operating results may fluctuate significantly as result of a
variety of factors, many of which are outside our control.  These factors
include:

     .    the short-term nature of some of our customer commitments;

     .    the lengthy sales and implementation cycle for some of our of our
          products and projects;

     .    patterns of information technology spending by customers;

     .    the timing, size, mix and customer acceptance of our product and
          service product offerings and those of our competitors;

     .    the timing and magnitude of required capital expenditures;

     .    the need to use outside contractors to complete some assignments; and

     .    general economic conditions.


As a result of these fluctuations, comparisons of quarterly results may not be
meaningful and should not be relied upon, nor will they necessarily reflect on
future performance.     

NEW ACCOUNTING STANDARDS
    
     In June 1998, the Financial Accounting Standards Board issued Statement
133, Accounting for Derivative Instruments and Hedging Activities. The new
statement established accounting and reporting standards for derivative
instruments and for hedging activities and is effective for all fiscal quarters
of fiscal years beginning after June 15, 1999.

     In March 1998, the American Institute of Certified Public Accountants
issued Statement of Position (SOP) 98-1, Accounting for the Costs of Computer
Software Developed     

                                      -60-
<PAGE>
 
    
or Obtained for Internal Use. SOP 98-1 provides guidance on accounting for the
costs of computer software developed or obtained for internal use, and is
effective for fiscal years beginning after December 15, 1998.

     In April 1998, the AICPA issued SOP 98-5, Reporting on the Costs of Start-
Up Activities.  SOP 98-5 provides guidance on the financial reporting of start-
up costs and organization costs, and requires these costs to be expensed as
incurred.  SOP 98-5 is effective for fiscal years beginning after December 15,
1998.

     In December 1998, the AICPA issued SOP 98-9.  SOP 98-9 amends paragraphs of
SOP 97-2 to require recognition of revenue using the residual method under some
circumstances, and is effective for fiscal years beginning after March 15, 1999.

     The adoption of these new standards is not expected to have a material
impact on our consolidated financial statements.

                             INDUSTRY INFORMATION

INTERNET DATA SECURITY INDUSTRY

     THE INTERNET DATA SECURITY MARKET
    
     Consumers, government agencies and corporations are increasingly relying
upon Internet Protocol Networks to conduct electronic commerce and
communications.  International Data Corporation estimates that the number of
Internet users will grow from 97 million in 1998 to 320 million in 2002, with
electronic commerce growing from $32 billion to $426 billion over the same
period.  The increasing proliferation of, and reliance upon, shared electronic
data has caused data security to become a paramount concern of businesses,
government, educational institutions and consumers.

     Demand for information security products is forecast by Datamonitor, an
independent research firm, to increase from $1.6 billion in 1997 to almost $7.0
billion by 2001, an annual growth rate of 44%.  In addition, Datamonitor
forecasts the Internet-security PKI segment to be the fastest growing segment of
this market, increasing from $75 million in 1997 to approximately $1.9 billion
by 2001, an annual growth rate of 124%.  The market for encryption technology is
estimated by Datamonitor to be the second fastest growing segment of the market
increasing from $168 million in 1997 to more than $1 billion in 2001.

     We believe our data security products provide the solution for entities and
consumers seeking to provide protection for their proprietary data.     

     INCREASING NEED FOR INTERNET DATA SECURITY

     In addition to protecting against unauthorized access to proprietary
information, data security affects an enterprise's ability to conduct electronic
commerce.  Companies such as Amazon.com, Inc., Bank of America, Cisco Systems,
Inc., Dell Computer Corp., eBay and E*Trade Group, Inc. have enjoyed dramatic
growth in their online customer base and revenue as consumers execute an
increasing number of transactions over the Internet.  The Internet's ease of
use, 24-hour availability, speed of delivery, global reach and ability to
simplify product and vendor comparisons are fueling this growth.  However,
consumer concerns about the trustworthiness and security of the Internet have
been one of the main impediments to even faster growth of electronic commerce
and other communications.  Hacking tools, such as password guessing and address
spoofing (or impersonation) programs, are freely available on the Internet and
bulletin board systems.  Merchants and consumers need assurances that consumers
making electronic purchases are correctly identified and confirmed and that the
confidentiality of information such as credit card and bank account numbers are
maintained.

     We believe that continued expansion of electronic commerce will require the
implementation of improved PKI security measures which will irrefutably verify
the identity of a party over the Internet and ensure that the information being
transmitted between that party and 

                                      -62-
<PAGE>
 
the other party is kept private. We also believe the security required to fuel
this continued expansion of electronic commerce and communication will be
provided through the continued advancement in PKI mathematical formulas referred
to as algorithms. Algorithms enable digital document signing and encryption of
proprietary data.
    
     As enterprises place an increasing reliance on electronic commerce and
communication, the need to protect confidential data from unauthorized intrusion
has become paramount. According to the Computer Security Institute, 78% of
respondents to its 1998 CSI/FBI Computer Crime and Security Survey reported that
they are connected to the Internet, but 39% of the respondents did not have a
first line of defense against unauthorized intrusion into their networks.
Unauthorized use of computer systems within the previous 12 months was reported
by 64% of these respondents, representing a 16% increase from the prior year.

     The consequences of unauthorized access, which is often undetected, can
range from theft of proprietary information or other assets to the alteration or
destruction of stored data.  The Computer Security Institute survey reports that
approximately 72% of respondent companies experienced a financial loss related
to information security and disaster recovery in the past two years.  According
to estimates by the Federal Bureau of Investigation, U.S. companies experience
estimated losses of $5 to $10 billion per year as a result of unauthorized
access to information and data.  The Yankee Group, an independent research firm,
estimates that network security breaches cost corporations in the U.S. over $5.0
billion per year in business losses, including productivity, customer confidence
and competitive advantage.     

     REQUIREMENTS FOR TRUSTED END-TO-END DATA SECURITY
    
     Today's client operating systems and Internet protocol-based networks lack
basic security and key Internet security features such as data privacy and
integrity, identification, authentication and auditing.     

     End-to-end data security concerns can be addressed by a variety of means.
Traditionally, enterprises relied heavily on passwords to restrict access to
proprietary information and materials. However, because of the risk of loss or
theft, more advanced protective measures have been developed to include
combinations of passwords and tokens with message encryption and personal
identification devices.  Regardless of the form of the data security device, the
level of security provided is evaluated based on a set of fundamental
principles, which include the following:
    
     .    IDENTIFICATION AND AUTHENTICATION. Verifies the identity of the
          authorized users to prevent unauthorized access to proprietary
          information and resources.

     .    CONFIDENTIALITY.  Involves the encryption of data transmissions so
          that only the intended recipient can access the information to ensure
          privacy.

     .    DATA INTEGRITY.  Ensures that data is not compromised or 
          manipulated.     

                                      -63-
<PAGE>
 
    
     .    NON-REPUDIATION.  Prevents the sender of data transmissions from
          disclaiming or "repudiating" authorship so that the sender cannot deny
          the occurrence of the transaction.

     .    AUDIT CONTROL.  Retraces information access and facilities use over a
          particular time period at a systems administration level so an
          enterprise can monitor and record authorized and unauthorized user
          activity.

     .    SECURED SYSTEM ADMINISTRATION.  Maintains and controls corporate
          intranets centrally through file encryption, password maintenance,
          audit control, certificate and cryptographic key management and device
          accessibility control.     

     The process of implementing Internet Protocol Network solutions requires
specialized skills lacking in most corporate information technology departments.
We provide the technology, products and services necessary for most companies to
implement or manage their data security infrastructure.

     CRYPTOGRAPHIC TECHNOLOGIES

     Cryptography is the process of encoding and decoding electronic messages
using mathematical algorithms, or ciphers, to enable the confidential
transmission of electronic messages to authorized persons.  Digital cryptography
is performed using a combination of symmetric ciphers (commonly referred to as
symmetric-key or secret-key cryptography) and asymmetric ciphers (commonly
referred to as asymmetric key or public-key cryptography), to achieve each of
the basic data security elements of identification and authentication,
confidentiality, integrity and non-repudiation.
    
     Both symmetric-key and asymmetric-key cryptography use an encrypting and a
decrypting key.  The decrypting key is user's unique number that is input to the
mathematical algorithm, or the cipher, used to encrypt or decrypt the message.
In symmetric-key cryptography, the encrypting key and the decrypting key, which
is secret, are identical.  Thus, to transmit a message, a secure key exchange
must be performed so that the key can be shared with the recipient of the
message.  In asymmetric-key cryptography, the encrypting key--a public key--and
the decrypting key--a secret key--are different and thus the public key can be
distributed to authorized recipients without risk of security breach.  Because
asymmetric cryptography allows for wide distribution of the encrypting key, it
permits secure communication among a large group of people without requiring
manual distribution of the key.  Additionally, asymmetric-key cryptography
relies on the generation of digital certificates which can be used to provide
the user authentication, data integrity and non-repudiation elements of the
information security system. However, public-key cryptography requires the use
of extremely complicated ciphers, so that encryption of large messages is
relatively slow when compared to encryption using secret-key cryptography.
Thus, asymmetric-key cryptography is commonly used to protect symmetric keys and
symmetric key cryptography is commonly used for bulk encryption.     

                                      -64-
<PAGE>
 
     IDENTIFICATION AND AUTHENTICATION
    
     Authentication of a user's identity is generally accomplished by passwords.
Because passwords are vulnerable to decoding or observation and subsequent use
by unauthorized persons, they are less secure than if used with tokens.  Tokens
are small devices ranging from simple credit card-like objects, rings, proximity
cards and plastic keys to more advanced secure tokens, including smartcards, PKI
cards and PCMCIA cards.  For greater protection, two-factor identification and
authentication is implemented by combining tokens with a password or personal
identification number to verify authentication of the user.  For added security,
three factor authentication which consists of token, password and biometric
comparisons, can be implemented.     

     PKI cards are credit card-sized semiconductor plastic cards that contain an
embedded microprocessor, memory, a secure operating system and the user's secret
key, password and digital certificates.  PKI cards have significant advantages
because of their ability to perform basic cryptographic functions on the card
itself rather than on the computer, thus reducing the risk that a breach of
security on the computer will lead to the unauthorized release of proprietary
information.  Through the use of PKI cards, E-mail messages, purchase orders,
credit card numbers, videoclips, data inquiries and other confidential
transmissions are secured as they are sent and therefore can be opened only by
the intended recipient.

     PCMCIA cards are parallel computer peripherals similar in size to a credit
card, though thicker, which contain multiple microprocessor chips.  PCMCIA cards
have greater storage capacity, higher data exchange rate and greater processing
power than conventional smartcards and therefore are capable of performing
advanced cryptographic functions that cannot be performed on a conventional
smartcard.  These advanced functions allow for use of more powerful algorithms
and thus provide for a greater overall level of security through the use of
PCMCIA cards.
    
     We are currently leading a joint effort with Atmel Corporation under a
contract with the National Security Agency to develop Forte, an ultra fast 32-
bit RISC microprocessor.  We are embedding the Forte chip into our new Forte
PKIcard, which we expect will be the world's fastest and most cryptographically
advanced PKI card.  We expect that Forte will provide PCMCIA level performance
at a price competitive with advanced smartcards.  Further, Forte is being
designed to be International Standards Organization compliant and therefore able
to be used in conventional reader/writers.     

     PKI DIGITAL CERTIFICATES
    
     The basic element of PKI, a cutting-edge development in the information
security field, is the digital certificate.  Digital certificate technology
provides a highly advanced form of authentication and secure key exchange.  PKI
digital certificates are specially prepared software files through which the
sender can digitally sign a message with a unique identification code. The
recipient of the message can authenticate the identity of the sender and verify
the integrity of the data through the use of a trusted third party known as a
certificate authority by     

                                      -65-
<PAGE>
 
    
obtaining the sender's public key from the certificate digitally signed by the
certificate authority. Furthermore, the uniqueness of the certificates provides
for non-repudiation, which prevents the sender from denying that it sent the
message and which is not available with less sophisticated techniques. With the
development of secure-token technology, digital certificates can now be
incorporated into smartcards, PKI cards and PCMCIA cards to provide an
information security system that provides two-factor identification and
authentication or three-factor identification and authentication with the
incorporation of biometric technology.

     Biometric technology utilizes fingerprints or other unique characteristics
of an individual to serve as a digital identification.  The use of digital
certificates is expanding rapidly across the Internet.  In fact, several states
now consider digital signatures contractually binding and there is a growing
acceptance within the federal government to effectuate transactions through the
use of digital certificates.     

SYSTEMS INTEGRATION AND NETWORKING SOLUTIONS INDUSTRY

     In recent years, there has been an increasing demand for open system
approaches designed to create interoperability among commercial off-the-shelf
computer software and hardware products manufactured by different suppliers.  In
addition, excessive development costs and the rapid pace of technological change
have led both governmental and commercial customers to demand more flexible
systems created by adapting readily-available commercial off-the-shelf software
and hardware.
    
     The emergence of the rapidly developing Internet protocol-based network
technologies in the 1990s has further fueled the demand for network computer
systems.  Although information technologies, secure data transmissions, and data
encryption have long been in use in the military intelligence arena, recent
technological advancements in computer hardware and software have now made these
applications economically viable for use by private companies.  This has given
rise to the need for specialized expertise in the areas of local and wide area
network design and installation, network management and operation and network
security, using new and complex information technology hardware and software
products.  Typically, the design and implementation of these systems in both
commercial enterprises and government agencies also involves the resale of the
hardware and software required for the system to the customer.

                                   BUSINESS

OVERVIEW
    
     Litronic provides professional Internet data security services and develops
and markets software and microprocessor-based products needed to secure
electronic commerce and communications over the Internet and other
communications networks based on Internet protocols.  Litronic's primary
technology offerings utilize PKI, which is the standard technology for securing
Internet-based commerce and communications.  PKI helps ensure the integrity and
privacy of information being transmitted and verifies the identity, authenticity
and authority of the sender and the recipient of that information.  To increase
sales capacity for its proprietary products and to capitalize on opportunities
in the rapidly growing Internet security market, simultaneously with the closing
of this offering, Litronic is acquiring Pulsar, a network integration solutions
company that specializes in deploying large-scale network solutions to
organizations in the commercial and government sectors.     

STRATEGY
    
     We believe that significant market opportunities exist due to the
increasing prevalence of electronic communication resulting from advancements in
Internet and electronic commerce technologies.  These opportunities are expected
to create a primary need for PKI.  Thus, we intend to pursue a strategy of
growth which is designed to capitalize on the market opportunities and the
competitive advantages we believe will result from the Pulsar acquisition.  Key
elements of our long-term business strategy include:

     .    INCREASING INTERNET MARKET PENETRATION.  We intend to capitalize on
          Pulsar's existing and significant client base and sales and marketing
          infrastructure to broaden and accelerate the market penetration of our
          comprehensive data security product offerings.  In our experience,
          large commercial accounts frequently seek to secure total integrated
          network security solutions from a limited number of suppliers.  We
          intend to utilize our brand recognition in the Internet Protocol
          Network security market and Pulsar's network implementation expertise
          and integration capabilities to support our efforts to gain greater
          market penetration.     

     .    INCREASING MARKETING OPPORTUNITIES.  The creation of a larger
          marketing and service organization, a higher market profile and
          greater financial strength is expected to generate greater
          opportunities for marketing our products in the U.S. and
          internationally.
    
     .    MAINTAINING TECHNOLOGICAL LEADERSHIP IN INTERNET PROTOCOL-BASED
          NETWORK SECURITY.  Through our industry-recognized research and
          development capabilities, we intend to upgrade and enhance our
          existing security products and develop new products to meet the
          expanding market's continually evolving requirements, technologies and
          standards.  Enhanced versions of ProFile Manager and     

                                      -67-

          Maestro are expected to be released in the third quarter of 1999. We
          believe that our research and development capabilities and the
          combined expertise of our technical staff position us to respond
          quickly and effectively to technological change, increased competition
          and market demands.

     .    EXPANDING PROFESSIONAL INTERNET PROTOCOL-BASED NETWORK SECURITY
          SERVICES.  We intend to provide our customers with a full range
          security services, including security policy assessments and
          evaluations, custom software development, integration and maintenance
          for the Internet and other Internet protocol based communications
          network.     

     .    EXPANDING AND LEVERAGING STRATEGIC ALLIANCES.  We intend to maintain
          and leverage existing strategic alliances and develop new strategic
          alliances with vendors with complementary technologies, products and
          services to maximize sales and market development opportunities.

     .    STRATEGIC ACQUISITIONS.  To the extent opportunities arise, we will
          seek to acquire other technologies, product lines and businesses which
          complement our products.

     .    INCREASING SALES PER CUSTOMER.  We will seek to increase average sales
          per customer based on our enhanced ability to offer system integration
          services in addition to our suite of data security products.
    
     .    MINIMIZING RISK OF SALES AND SERVICE DELAYS.  The unavailability of
          skilled professionals in the information technology and Internet
          security solution outsourcing and integration sectors has in the past
          caused companies with advanced proprietary technologies to experience
          sales and service delays.  By bringing together our research and
          development staff and Pulsar's existing sales and technical personnel
          and procedures, we aim to minimize the risk of these delays.

     .    INCREASING INTERNATIONAL SALES.  We will seek to generate additional
          sales in foreign markets by establishing a network of international
          distributors and value-added resellers.  The U.S. government has
          recently relaxed the export restrictions for our ProFile Manager,
          NetSign and other strong encryption products.  These products may now
          be exported without a license to most countries for use by banks,
          online merchants, healthcare, insurance organizations and overseas
          subsidiaries of U.S. companies.  To capitalize on these opportunities,
          we are in the process of building or have built relationships with
          distributors and resellers with computer security expertise in these
          market sectors:

                    .    we have appointed distributors in Japan and Spain;

                    .    we are negotiating with potential distributors and
                         resellers in     

                                      -68-
<PAGE>
 
    
                      Europe, Africa and Asia; and

                    . we intend to appoint a director of international sales who
                      will be responsible for the management of our
                      international distributor network.    
                      
In addition, we expect to experience the following synergistic benefits as a
result of our acquisition of Pulsar:
    
     .    EXPERIENCE OF MANAGEMENT, KEY PERSONNEL AND CONSULTANTS.  We believe
          the added depth, breadth and experience of Pulsar's management team,
          key employees and consultants enhances our ability to successfully
          implement our business strategy.

     .    COMPREHENSIVE DATA SECURITY PRODUCTS AND SERVICES OFFERING.  We
          believe we can satisfy the comprehensive requirements of enterprises
          through the combination of our open-architecture, open-platform, open-
          token and algorithm-independent technologies and products and Pulsar's
          networking solution services.  We believe our ability to offer
          synergistic products and services distinguishes us from other PKI
          information technology solution providers by enabling us to provide
          comprehensive information security systems rather than addressing only
          selected aspects of customers' data security needs.

     .    SOLUTIONS ADDRESSING THE KEY ELEMENTS OF INTERNET DATA SECURITY.
          Unlike other integrators that rely on reselling of products produced
          by other vendors to respond to the needs of an enterprise, we develop,
          manufacture and market many of the applications, software,
          cryptographic libraries, readers/writers and tokens that are required
          to create comprehensive token-based PKI security solutions that
          address the key data security elements of:  identification and
          authentication; confidentiality; data integrity; non-repudiation;
          audit control; and system administration.

Additionally, because our applications are open standards, we can integrate
products and services of other vendors into our products to enhance our
solutions capability.     

INTERNET DATA SECURITY PRODUCTS

     GENERAL
    
     Our Internet data security products provide the highest level of
commercially-available security for secure E-mail, secure file transport, file
protection, remote access, authentication and authorization in an open multi-
platform standards-based framework.  The foundation of our Internet data
security products is our extensive cryptographic library and device drivers
supporting numerous different operating system platforms and token management
systems which enable users to seamlessly integrate token-based security
enhancements into existing networking     

                                      -69-
<PAGE>
 
    
environments or into newly designed and implemented networks. Our products can
also be used by software developers to add token-based information security to
applications such as browsers, firewalls, E-mail systems, database management
systems and other client/server applications.

     Our data security products are designed with an open architecture, so they
can operate independently of:

     .    algorithms -- the security products are designed to use different
          suites of algorithms depending upon the application requirements, for
          example, military or banking and finance.

     .    platforms -- the security products may be used with many different
          computer types and operating systems, for example, Windows, UNIX, and
          MacIntosh.

     .    applications -- the security products may be used with various
          software applications, for example, e-mail, e-commerce, database
          systems or word processors.

     .    tokens -- the security products function with various types of tokens,
          for example, software tokens, smartcards and PC cards.

     As a result of this open architecture, these products are compatible with
virtually all commonly used network hardware.  Algorithm independence allows our
products to be tailored to numerous encryption algorithms through software
selection.  As a result, our libraries, drivers and security devices are
compatible with a variety of encryption algorithms, and popular software
applications and operating systems.  We develop and embed these cryptographic
technologies in a multitude of devices and tokens, including smartcards, PKI
cards, PCMCIA cards, embedded industry standard architecture (ISA) and
peripheral component interconnect (PCI) bus cards.  We are also working with
other companies to implement use of PCMCIA cards, PKI cards and smartcards to
support biometric technologies such as fingerprint and voice recognition.  These
products provide the added protection of a security token utilizing public key
cryptography, key exchange techniques and electronic signatures on most popular
operating systems and hardware platforms.  In addition, our technologies permit
functions to be scaled as performance and pricing requirements dictate.

E-mail, desk-top file encryption and secure remote network access.

     INTERNET CRYPTOGRAPHIC API DEVELOPER TOOLKITS     

     CRYPTOS SDK AND CRYPTOS SDK+.  CryptOS SDK products are cryptographic APIs
that allow application developers to use off-the-shelf or custom application
software to integrate smartcard technology into existing systems, thus adding
hardware-strength security to software-only systems.  CryptOS SDK is bundled
with a smartcard reader/writer and smartcards. CryptOS SDK+ has additional tools
for Java programming.
    
     MAESTRO.  Maestro, a product we have only recently introduced to the
market, is a multi-protocol cryptographic library that enables software
developers to incorporate secure token-based, symmetric and asymmetric key
cryptography into their application software. Maestro is a multi/concurrent
access, cross-platform system that supports multiple types of tokens such as
smartcards, PCMCIA cards and cryptographic algorithms.  Coupled with token
reader/writers, Maestro supports devices over commonly-used interfaces,
including keyboard, serial, small computer system interface (SCSI), parallel
port and Universal Serial Bus.  Maestro currently supports two commonly used
cryptographic interface protocols.  We are developing additional protocol
adapters to expand the functionality of Maestro.  Maestro is compatible with
Windows 95, 98 and NT operating systems as well as all popular UNIX 
platforms.     

     TOKENS
    
     ISO SMARTCARDS.  We offer a family of off-the-shelf international standard
organization (ISO) standard smartcards ranging from storage-only cards to cards
containing cryptographic capabilities.

     MONIKER, PC-CRYPTOCARD.  We also offer Moniker, a Fortezza standard PCMCIA
card. The Fortezza standard PCMCIA cards are commonly used by the Department of
Defense, as well as by other governmental and commercial entities.

     FORTE PKICARD.  We are in the process of developing a next generation PKI
card, the Forte PKIcard, in cooperation with Atmel Corporation.  Forte is a 32-
bit RISC microprocessor which is being designed with a high speed Universal
Serial Bus interface in addition to the ISO interface.  Forte is also to be
designed with a larger storage capacity and processing speed than existing
smartcards.  The Forte PKIcard is expected to be manufactured in the U.S. and we
anticipate shipments to begin in late 1999.     

                                      -71-
<PAGE>
 
    
     OTHER TOKENS.  Because our products are open-architecture, open-platform,
open-token, algorithm and API-independent, we offer third-party tokens, such as
PCMCIA cards, smartcards, rings, proximity cards and plastic keys and other
commercially available tokens, for use with our reader/writers and application
software.     

     TOKEN READER/WRITERS
    
     A token reader/writer is a hardware component that electronically reads the
content of a smartcard, PCMCIA card, or PKI card.  We manufacture several
different types of reader/writers. Following is a brief description of their
features.     

     SERIAL AND KEYBOARD PORT SMARTCARD AND PKI CARD READER/WRITERS.  We sell
our reader/writers as a security product component or bundled with other
products such as ProFile Manager, NetSign and/or CryptOS SDK to provide token-
based data security solutions.
    
     We manufacture and sell compact, hand-held smartcard reader/writers that
interface through the RS-232 serial port of a PC or workstation.  The Series 215
and 220 reader/writers are compatible with Windows 95, 98, NT and UNIX and
MacIntosh operating systems.  The Series 220 reader/writer can optionally be
connected through the keyboard port which provides the added security of a
protected personal identification number, or PIN, path.  With a protected PIN
path, the password authentication is intercepted by the reader/writer thus
preventing a hacker from implanting an unauthorized program in the PC to
intercept the password.  We offer a Series 230 reader/writer which is integrated
into a keyboard, and also offer a Series 410 reader/writer which connects to a
computer through its PCMCIA slot.

     ARGUS 300.  The ARGUS 300 consists of a tamper-resistant ISA board and
external reader/writer and is connected to the keyboard.  The ARGUS 300
incorporates DES encryption technologies and offers additional security features
such as boot protection, electronic commerce security and protected PIN path
directly through the board rather than through an external device that might be
tampered with by an unauthorized user.  The ARGUS 300 is validated for
electronic signature by the National Institute of Standards and Technology
(NIST), the U.S. Treasury  Department and General Accounting Office.

     PCMCIA CLIENT READER/WRITER.  We offer a series of single-and dual-socket
PCMCIA card reader/writers that interface via various ports such as SCSI
(internal and external reader/writer), ISA bus (internal reader/writer), PCI bus
(internal reader/writer), Universal Serial Bus and parallel port (external
reader/writer).  These reader/writers incorporate our proprietary device drivers
which provide the interface between the reader/writer and its application
software such as Maestro and third-party application software.     

     CIPHERSERVER.  We offer a reader/writer that contains sockets for up to
eight PCMCIA cards, is used on the enterprise's server side and incorporates the
device drivers and other technologies of our other PCMCIA readers.  CipherServer
interfaces with the host server to enable the host server to provide
rapid/simultaneous processing of cryptographic functions received from numerous
clients.

OTHER CUSTOM-DESIGNED SECURITY PRODUCTS

     SECURE PCS
    
     We offer a family of secure, year 2000 compliant, servers which are based
on a two-state workstation technology that operate in either the secured state
or the public state.  A transition between the two states causes all temporary
data in the volatile memory to be fully erased.  This process precludes an
unauthorized subsequent user from accessing the classified information that
would otherwise be resident in the system's memory.     

     MANAGED FIREWALL AND VIRTUAL PRIVATE NETWORKS SOLUTIONS
    
     We offer secure architecture based firewall and virtual private networks
gateway technology using intrusion detection software for high data capacity and
scalable security solutions.  These software and hardware systems provide for
multi-user remote administration, and integrated management of multiple security
policies and firewalls.     

     NETWORK SECURITY AND MANAGEMENT TOOLS
    
     Our network security and management tools are a scalable, comprehensive
collection of network security and management solutions assembled into an
integrated security suite of hardware and software.  The tools include a multi-
tiered approach to virus protection covering the client, server and Internet
gateway through a combination of encryption, firewall and virtual private
networks technologies.  These tools protect networking systems against attacks,
and compromise and loss, while maintaining the integrity of business functions
and data.  These products ensure full network performance with a proactive
approach by fixing problems, planning growth and optimizing functionality and
reliability.

THE ASSURE TECHNOLOGY

     The Assure technology which we will seek to purchase, subject to the
satisfactory completion of our due diligence, was developed to create
information security products to protect information in a client/server network
operating system with a high level of security.  The Assure technology was
designed to equip client/server networks with a proprietary encryption process
to encrypt data before it is transmitted, generate unique message authentication
codes and encode the data upon receipt by an authenticated user.  Therefore, all
data transmitted through the network would be in a encrypted format, rendering
it unintelligible to recipients who do not have a proprietary decrypting key.

     A product based on the Assure technology, Assure EC4.11, was evaluated by
the National Computer Security Center in connection with an early version of
Novell's 4.11 network operating system.  Assure EC4.11 received a Class C2
rating as a result of this evaluation, but no product based on the technology
was ever marketed.  If we successfully purchase the Assure technology, we intend
to use a portion of the proceeds of this offering     

                                      -73-

PRODUCT RESELLING
    
     Historically, a substantial portion of our product resale revenues were
derived from sales of low-end, low-margin computer and network security
products.  We are increasingly shifting our focus in the reseller market,
primarily in the government information technology segment, to sales of high-
end, high-margin specialized computer and network security products and
customized configurations of these products.     

                                      -75-

                                      -77-
<PAGE>
 
     DIRECT MARKETING EFFORT
    
     As of April 1, 1999, we employed a direct sales and marketing force of 31
individuals located in offices in California, the Washington, D.C. area and
Atlanta, Georgia to market our products and services to industry and vertical
market segments, including e-commerce, financial, telecommunications, healthcare
and information services companies and federal, state, local and foreign
government agencies.  Our sales force is responsible for soliciting prospective
customers and providing technical advice and support with respect to our
products and services. Additionally, we use telemarketing efforts to target
commercial accounts and federal government agencies.  We seek to achieve greater
vertical market penetration by using direct sales personnel with significant
market expertise, as well as consultants with established relationships in the
commercial marketplace.

     Following the closing of this offering, we intend to expand our direct
sales force to increase the number of representatives located in our California,
Georgia and Washington, D.C. offices.  We may also open direct sales force
offices in other geographic locations as we determine our clients' needs and our
market opportunities.     

     INDIRECT MARKETING EFFORT
    
     An important component of our sales strategy is the development of indirect
sales channels such as systems integrators, value-added network service
providers and original equipment manufacturers.  Currently, we use these
indirect sales channels to augment the efforts of our direct sales forces.

     We also use the services of third-party consultants with established
relationships and contacts with prospective customers to which we would not
otherwise have access.  As part of our expansion strategy, we will seek to
develop relationships with additional third-party sales channels.     

     STRATEGIC ALLIANCES
    
     We plan to increase our vertical market penetration by continuing to
develop strategic alliances with other companies in the data security and
network integration industries.  We have developed significant strategic
alliances with companies in an effort to:

    .     incorporate our products into third-parties' products;

    .     jointly develop products and services;

    .     conduct joint research and development efforts;

    .     jointly conduct proposals and presentations for products and services
          and reseller arrangements.     

                                      -78-
<PAGE>
 
    
     These alliances assist us in expanding our marketing and technical
capabilities and are intended to increase the distribution and market acceptance
of our Internet, intranet and extranet security products and services.     

     We believe that strategic alliances allow us to cost-effectively integrate
third-party products into our product offerings to provide our clients with
customized information technology solutions.  Our strategic alliances currently
include the following:
    
     .    NETSCAPE AND MICROSOFT - we provide enhanced E-mail security features
          to their browser programs through integration of our NetSign product
          lines.

     .    VERISIGN - we have a marketing agreement with VeriSign and act as
          VeriSign's recommended PKI card partner.

     .    ATMEL CORPORATION - we have an alliance with Atmel Corporation in
          which we are jointly developing Forte, an advanced microprocessor,

     Additionally, Pulsar has formed alliances with a number of equipment
manufacturers to generate leads for its technology product sales, including
Lucent Technologies, Inc., Photon Vision Systems LLC, Northern Computers, Inc.,
Hewlett-Packard Company and International Business Machines Corp.  We expect
these alliances to generate qualified leads for our sales force to contact and
close.     

     SALES TO THE GOVERNMENT INFORMATION TECHNOLOGY MARKET
    
     The government information technology market is generally characterized by
highly-structured procurement rules and procedures, large contracts, a
relatively long sales cycle, significant barriers to entry and low collection
risks.  In response to these characteristics and requirements, a number of
avenues, such as General Service Administration schedule     

                                      -79-
<PAGE>
 
    
contracts, blanket purchase agreements and bidding procedures, have been
developed to access this market.

     The General Services Administration, which is the central procurement
agency for the U.S. government, negotiates schedule contracts. Government
agencies and other authorized purchasers, although not required to do so, may
purchase goods and professional services under GSA schedule contracts at
predetermined price ceilings, terms and conditions. GSA schedule contracts are
awarded on the basis of a number of factors, the most important of which are
compliance with applicable government regulations and the prices of the products
to be sold. A blanket purchase agreement, or BPA, is a simplified but non-
mandatory, fixed-price,indefinite delivery-indefinite quantity, contract for the
government to purchase products, at pre-negotiated terms and conditions.
Purchases made under BPAs are often paid for with a government-issued credit
card. Federal government agencies are authorized to enter into BPAs with GSA
schedule holders. The GSA-authorized BPAs incorporate many terms and conditions
of GSA schedule contracts, often at lower prices than available on the GSA
schedules.

     A significant portion of the purchases of computer products and services by
the federal government are made under contracts or purchase orders awarded
through formal competitive bids and negotiated procurements. Substantially all
of these bids are awarded on the basis of a number of factors, including the
best value to the government, which, depending on the bid, can be a combination
of price, technical expertise, past performance on other government contracts.
Major procurements can exceed millions of dollars in total revenue for a
reseller, span many years, and provide a purchasing vehicle for many agencies.
In addition, networking products are purchased by the federal government through
open-market procurements. These procurements are separate and apart from GSA
schedules, and include simplified acquisition procedures, requests for quotes,
invitations for bids and requests for proposals. Most purchases in the state and
local government market are made through individual competitive procurements.
State and local procurements typically require formal responses and the posting
of bid bonds or performance bonds to ensure complete and proper service by a
prospective bidder. Each state maintains a separate code of procurement
regulations that must be understood and complied with by entities selling
products to the state.

     We are on most government bid lists relevant to our product offerings and
respond with proposals to hundreds of bid solicitations each year. In addition,
our marketing employees actively prepare bids for federal, state and local
government agencies for open market procurements. After the closing of this
offering, we intend to expand our bid proposal unit to compete and capture
additional projects submitted for proposal.     

     ADVERTISING
    
     Our marketing efforts include maintaining a web site, Internet advertising,
including hot links with other web sites, direct mail, public relations, events,
sales tools, broadcast messaging, telemarketing and corporate marketing
materials. We believe that our future business activity depends in part on our
marketing and sales through the Internet. Our website describes     

                                      -80-
<PAGE>
     
our business, products and services. We are currently in the process of
integrating Pulsar's website material and upgrading our site to allow for
automated on-line purchases.

     Our public relation efforts are designed to target the appropriate press
coverage and consist of press kits, targeted media lists and press releases.
These efforts are designed to complement our sales and marketing efforts.     

     TRADE SHOWS AND PRESENTATIONS

     We attend and exhibit our products and services at trade shows in the U.S.
and internationally each year in an effort to increase our market exposure. We
intend to continue to attend trade shows as well as to make joint presentations
with strategic partners to prospective customers relating to products and
services. 

SUPPLIERS
    
     Some of the components incorporated into our Internet data security
products are produced by other vendors. We also integrate third-party products
and components into the networks we design and develop for our customers. To
maintain quality control and enhance working relationships, we generally rely on
multiple vendors for these products. However, some of these products are
produced or sold only by a single supplier, thus presenting a risk that they may
not be available on commercially reasonable terms in the future or at all. While
we believe that alternative sources of supply could be obtained, our inability
to develop alternative sources if, and as required, in the future could result
in delays or reductions in product shipments that could adversely affect our
business.     

RESEARCH AND DEVELOPMENT

     We conduct extensive research and development efforts which focus on the
development of cryptographic PKI software and hardware products that can be
readily integrated and adapted to the expanding requirements of the Internet,
intranets and extranets. After the closing of this offering, we expect to devote
substantial additional research and development resources to enhance our data
security product line.

     Our current research and development efforts include:
    
     .    Expanding Maestro to offer additional application program interfaces,
          including Microsoft's CAPI (a cryptographic API) for Windows 95/98 and
          Windows NT; further, expanding the suite of tokens supported by
          Maestro;

     .    Expanding the capabilities of ProFile Manager to provide certificate
          exchange features with additional third-party certificate authorities
          and increased capability for the PKI enterprise manager;     

     .    Developing Forte, an advanced 32-bit RISC microprocessor which we are
          embedding in our Forte PKIcard.  We expect the Forte PKIcard will be
          an ISO

                                      -81-

          standard smartcard with greater flexibility and a higher degree of
          processing power than existing PKI cards, due in part to the inclusion
          of a Universal Serial Bus interface on-board the microprocessor chip.
          Given that Forte is an advanced security chip that will provide
          advanced security features, we expect to be able to embed it in a
          variety of devices, including PC mother boards;

     .    Developing series of Universal Serial Bus interface 
          reader/writers;     

     .    Developing technologies to incorporate biometric technologies into
          Litronic PKI products to provide further advanced identification and
          authentication protection;

     .    Expanding the security features of applications programs such as
          NetSign and NetSign PRO; and
    
     .    Developing a version of the ARGUS 300 for the PCI bus while retaining
          its validation by the NIST. The ARGUS 300 is currently an ISA bus
          security product that has been validated by the NIST for a security
          level approved for digital signature operations. Newer computer
          designs now have the PCI architecture. The PCI version of the ARGUS
          300 is being designed to enable the NIST to extend the certification
          to the new PCI design without a complete new laboratory validation
          process.     

     The process of developing our products and services is extremely complex
and requires significant continuing development efforts. There is a risk that we
will not successfully develop and market new products or product enhancements
that respond to technological change and evolving industry standards and
customer requirements in a timely manner.
    
     As of April 1, 1999, our research and development staff consisted of 25
employees, of whom 22 were engineers. Approximately 90% of these engineers were
engaged principally in the development of software, including cryptographic
libraries and device drivers. Our retention rate for our research and
development staff over the past three years is 80%. We believe that our ability
to attract and retain qualified development personnel is essential to the
continued success of our development programs. The market for these personnel is
highly competitive and our development activities could be adversely affected if
we are unsuccessful in attracting and retaining skilled technical personnel.

     During the years ended December 31, 1996, 1997 and 1998, our net expenses
for research and development were $752,000, $1.2 million and $1.3 million. We
have allocated $6.2 million of the proceeds of this offering for research and
development activities.     

COMPETITION
    
     We compete in numerous markets, including;

     .    Internet and intranet electronic security;     

                                      -82-
<PAGE>
 
    
     .    access control;                             
     .    token authentication;                       
     .    smartcard-based security applications;      
     .    electronic commerce applications;           
     .    systems integration;                        
     .    product reselling; and                      
     .    government information technology markets.  

     The markets for our products and services are intensely competitive and are
characterized by rapidly changing technology and industry standards, evolving
user needs and the frequent introduction of new products. We believe that the
principal factors affecting competition in our markets include:

     .    product functionality;
     .    performance;
     .    flexibility and features;
     .    use of open standards technology;
     .    quality of service and support;
     .    company reputation; and
     .    price.

     We face significant competition from a number of different sources. Many of
our competitors are more established, benefit from greater name recognition and
have substantially greater financial, technical and marketing resources than we
have. One of our significant competitors is Microsoft Corporation, which has
recently announced its intention to begin making smartcards. Some of our other
significant data security competitors include:

     .    International Business Machines Corp.
     .    Motorola, Inc.
     .    RSA Data Security, Inc.
     .    Network Associates, Inc.
     .    Secure Computing Corporation
     .    Rainbow Technologies, Inc.

     Some of our competitors for systems integration and product reselling
     include:

     .    BTG, Inc.
     .    Inacom Corporation
     .    Government Technology Services, Inc.

     In addition there are several smaller or start-up companies with which we
compete from time to time. We also expect that competition will increase as a
result of consolidation in the information security technology and product
reseller industries. We may be unable to compete successfully in the future with
our competitors, which may adversely affect our business.

INTELLECTUAL PROPERTY
    
     We depend substantially on our proprietary information and technologies. We
rely on a combination of trademark, patent, copyright and trade secret laws,
employee and third-party non-disclosure agreements, technical measures and other
methods to protect our software products and other proprietary technologies and
know-how. We also rely on standardized license agreements that are not signed by
the end user to license our products and, therefore, may not always be
unenforceable.

     We currently have two patents registered with the U.S. Patent and Trademark
Office and three patent applications pending with the U.S. Patent and Trademark
Office that cover aspects of data security technology. Prosecution of these
patent applications and any other patent applications that we may subsequently
determine to file may require the expenditure of substantial resources. The
issuance of a patent from the filing of a patent application is a lengthy
process. Our technology may become obsolete while our applications for patents
are pending. Further, any pending or future patent may not be granted, and any
future patents may be challenged, invalidated or circumvented and the scope of
any patents may be reduced. The rights granted to us through our patents may not
provide us with any advantages. We have not pursued any patent protection
outside the U.S. for any technology.     

     Our technical measures and non-disclosure agreements may not be adequate to
prevent misappropriation or provide any meaningful protection for our
proprietary technology in the event of misappropriation. Further, others may
independently develop substantially equivalent or superior technologies or
duplicate any technology we develop, or our technology may infringe on the
patents, copyrights or other intellectual property rights owned by others.

     We may also be at risk when we enter into transactions in countries where
intellectual property laws are not well developed or are poorly enforced. Legal
protection of our rights may be ineffective in foreign markets, and technology
manufactured or sold abroad may not be protectable in jurisdictions in
circumstances where protection is ordinarily available in the U.S.

     We believe that, due to the rapid pace of technological innovation for
network security products, our ability to establish, and if established,
maintain a position of technological leadership in the industry, is dependent
more upon the skills of our development personnel than upon legal protections
afforded our existing or future technology.
    
     Because our products are designed with an open architecture and are
algorithm-independent, they can be utilized with a variety of encryption
algorithms. Some algorithms are in the public domain and can be incorporated
into our products at no charge. To the extent that a customer desires to
incorporate a proprietary algorithm into a security solution, we or the customer
must obtain a license from the algorithm owner. Depending on the algorithm and
its owner, the license fee may be a flat fee, a per unit royalty or a
combination of the two.     

                                      -84-

     We are developing Forte under a task order issued under a contract with
National Security Agency. The contract incorporates the Department of Defense's
standard licenses for technical data and computer software, commonly known as
the data rights clauses. Data rights clauses are only applicable to data or
software actually delivered to the federal government under a contract. If the
data rights clauses were applicable to our agreement with the National Security
Agency to develop Forte, one of the data rights licenses, commonly called a
government purpose rights license, would permit the federal government to create
second sources of supply of the Forte technical data and source code for itself
without paying us royalties. The government purpose license clause would not
authorize the Federal government to create competitors to us in the commercial
market. We do not believe the data rights clauses generally, or the government
purpose license specifically, apply to Forte because our contract with the
National Security Agency does not provide for the delivery of Forte to the
federal government. The task order provides that the National Security Agency
will obtain detailed design information about Forte.     

GOVERNMENT REGULATION
    
     Because we sell our products internationally, we must comply with federal
laws regulating the export of, and applicable foreign government laws regulating
the import of, our products. The U.S. government has recently relaxed the export
restrictions for our NetSign and ProFile Manager products. However, the federal
government may rescind these approvals at any time. Under current regulations
these products can be exported without a license to most countries for use by
banks, healthcare, insurance organizations and overseas subsidiaries of U.S.
companies.

     Additionally, we may apply for export approval, on a specific criteria
basis, for our future products. Government export regulation for security
products is less stringent for products designed for banking and finance, e-
commerce, health, insurance and for use by U.S. subsidiaries. We may not receive
approval to export any future products on a timely basis, on the basis we
request or at all. As a result of government regulation of our products, we may
be at a disadvantage in competing for international sales compared to foreign
companies that are not subject to these restrictions.     

EMPLOYEES
    
     As of April 1, 1999, Litronic employed 64 full-time and four part-time
people, including 40 in product management, research, development and support,
two in professional services, 14 in field operations including sales, marketing
and customer management, and 12 in finance, human resources, business
development, legal and administration. As of April 1, 1999, Pulsar employed 61
people, including four in product management, 17 in professional services, 17 in
field operations including sales, marketing and customer management, and 23 in
finance, human resources, business development, legal and administration. After
the closing of this offering, we expect to integrate Pulsar's workforce.     

                                      -85-
<PAGE>
 
     Our employees are not represented by labor unions. We do not expect that
any of our employees will be represented by any labor unions after the closing
of this offering. We consider our relations with our employees to be good.

FACILITIES
    
     After the closing of this offering, we will be headquartered in Irvine,
California where we currently lease approximately 12,000 square feet of office
space for our executive offices with a lease expiring in September 2001 and
approximately 1,800 square feet of space in a production and warehouse facility
and which has a lease expiring in June 1999. In addition, after the closing of
this offering, we will conduct a significant portion of our operations at
Pulsar's offices in our 12,700 square foot Lanham, Maryland facility, which we
use as office space for our executive offices and as warehouse space, under a
lease that expires in 2003.     

LEGAL PROCEEDINGS
    
     We are involved from time to time in routine litigation that arises in the
ordinary course of business. We are not currently involved in any litigation
which we believe will have a material impact on our results of operations,
financial condition or liquidity, other than the following:

     In the course of its business, Pulsar has been extended credit from several
trade vendors for the purchase of supplies, equipment, merchandise and services.
Pulsar's accounts for several of these trade vendors have been past due for a
significant amount of time. As a result, several of these trade vendors have
filed lawsuits against Pulsar seeking to collect the amounts owed by Pulsar.  In
addition, Prince George's County, Maryland has filed a lawsuit against Pulsar
to collect personal property taxes in the amount of $38,500.  Aggregate amount
claimed under these lawsuits was approximately $1.6 million, exclusive of
interest and costs. Pulsar has entered into settlement agreements covering some
of the lawsuits and as of April 1, 1999 has paid in excess of $600,000 under
those agreements. As of April 1, 1999, the aggregate amount Pulsar owes on
claims that have been filed and settled is approximately $250,000. The aggregate
amount of claims that have been filed but not settled is approximately $731,000.
We intend to use our new term loan and anticipated cash flow from operations to
resolve and pay these claims and settlements. See "Management Discussion &
Analysis of Financial Condition and Results of Operation."

     On January 16, 1998, G2 Resources Inc. filed a complaint against Pulsar in
the Circuit Court, Fifteenth Judicial Circuit, Palm Beach County, Florida. G2
claims that Pulsar breached a contract under which G2 agreed to provide services
related to the monitoring of government contracts available for bid and the
preparation and submission of bids on behalf of Pulsar. The contract provides
that Pulsar pay G2 $500,000 in 30 monthly installments of $16,666 and an
additional fee of 2% of the gross dollar amount generated by awards. In its
complaint, G2 alleged that Pulsar failed to make payments     

                                      -86-
<PAGE>

     
under the contract and claimed damages in excess of $525,000 plus interest,
costs and attorneys fees. In the course of discovery G2 asserted that its
losses/costs arising out of its claim amount to approximately $10.3 million.
Pulsar has asserted that G2 failed to perform the services required under the
contract and Pulsar filed a claim for compensatory damages, interest and
attorneys fees against G2. Classical Financial Services, LLC intervened in the
case. Classical claims that G2 assigned its accounts receivable to Classical
under a financing program and that Pulsar breached its obligations to Classical
by failing to make payments under the contract with G2. Pulsar has asserted
defenses to Classical's claim. Pulsar believes that the claims of G2 and
Classical against Pulsar are without merit and intends to continue to vigorously
defend against the claims. If G2 or Classical were to prevail in this lawsuit,
our business and financial condition could be materially adversely affected.

     On July 11, 1997, Rudolph Menna filed a complaint against Pulsar and
William W. Davis, Sr. in the U.S. District Court for Northern District of
Georgia, Atlanta Division. Mr. Menna alleges that he was wrongfully terminated
as a Pulsar employee and that Pulsar and Mr. Davis unlawfully discriminated
against him on the basis of race and age. Mr. Menna's complaint seeks an
unspecified amount of damages including back pay, front pay, benefits,
compensatory and punitive damages, interest and attorneys fees. Pulsar and Mr.
Davis have filed an answer denying the material allegations in the complaint.
Pulsar and Mr. Davis believe that Mr. Menna's lawsuit is without merit and
intend to continue to vigorously defend against it. If Mr. Menna were to prevail
in the suit our business and financial condition could be materially adversely
affected.

   Chief Executive Officer
   and Chairman of the Board
</TABLE>

     Mr. Shah also received other fringe benefits from Litronic in his capacity
as chief executive officer and chairman of the board; however, those benefits
were less than $50,000 during the year ended December 31, 1998.

     We anticipate that during the fiscal year ending December 31, 1999 the only
executive officers that will earn $100,000 or more will be Messrs. Shah, Davis
and Gray.

EMPLOYMENT AGREEMENTS
    
     GENERAL     

                                      -93-
<PAGE>
 
    
     Kris Shah and William Davis have each entered into a 2-year employment
agreement with Litronic, effective as of the date of the offering.  The
agreement provides that after the initial term it will automatically renew for
successive one year terms unless it is terminated by us or by the employee
through written notice given to the other party 90 days before the expiration of
the then current term.  The agreements provide that Messrs. Shah and Davis will
each receive an annual salary of $175,000 for the 12-month period following the
date of this prospectus. Thereafter, their salaries may be adjusted by our
compensation committee.  Each of Messrs. Shah and Davis are also entitled to
receive annual bonus awards of $100,000 if we have earnings of $2.5 million or
more and an additional $37,500 for each additional $1 million of earnings in
excess of $2.5 million.

In making the calculation for the bonuses we will measure earnings before
interest and taxes and will add back the amortization of goodwill resulting from
the Pulsar acquisition.     

     TERMINATION OF EMPLOYMENT
    
     Each employment agreement provides that, in addition to being terminated
through the notice features described above, employment may be terminated as
follows:

     .    by the employee if the employee has good reason to terminate the
          agreement. Good reason exists if:

          .    the employee is relieved of his position as, or is not
               reappointed as, an officer of our company;

          .    the employee's title, office or responsibilities change
               substantially;

          .    the employee's base salary is reduced to an amount that is less
               than $175,000 or by more than 10%;

          .    we fail to maintain our employee benefit plan;

          .    we sell or transfer our company and fail to obtain the
               successor's assumption of the employment agreement; or

          .    we fail to comply with a material term of the employment
               agreement and fail to cure our default after appropriate notice.

     .    by us if we determine that due cause for termination exists. Due cause
          exists if we find that the employee:

          .    intentionally misapplied our money or property;

          .    committed an act of dishonesty that harmed our company;

          .    was convicted of a felony or a crime involving moral turpitude;

          .    has used a controlled substance, including alcohol, which affects
               his ability to perform his job duties; or    

                                      -94-
<PAGE>
 
    
          .    breached the terms of the employee agreement.


     .    Additionally, we can terminate the agreement upon the employee's:

          .    death;

          .    disability for more than 180 days after we give 30 days notice of
               our intention to terminate the agreement; or

          .    retirement.

     Finally, we can terminate the employment agreement for any other reason, at
any time, but we will be deemed to have constructively terminated the agreement
and will be liable to pay the employee the severance payment described below.

     PAYMENT UPON TERMINATION

     We may be obligated to make payments to the employee upon termination of
employment depending on the circumstances surrounding the termination.
Following is a description of situations in which we may or may not be obligated
to make severance payments:

     .    If the employment agreement is terminated by the employee after giving
          notice, by us for cause or by the employee in breach of the agreement,
          we will not be obligated to pay any compensation after the termination
          date, except:

          .    employee benefits;

          .    unpaid base salary the employee has earned which we have not yet
               paid; and

          .    vested stock options.

     .    If the employment agreement is terminated by the employee for good
          cause or by us through a constructive termination, we will be
          obligated to pay the employee:

          .    his annual salary through the latter of the end of the employment
               agreement term or a period of two years;

          .    a pro rata bonus for the fiscal year in which the termination
               occurs;

          .    continuing medical and life employee benefits for six months
               after the termination; and

          .    vested stock options.


     CONFIDENTIALITY AND NONCOMPETE CLAUSES     

                                      -95-
<PAGE>
 
    
     Each of the employment agreements also contains noncompete, confidentiality
and nondisclosure clauses designed to protect our intellectual property.
Additionally, each agreement contains a provision designed to preclude the
employee from claiming rights to any products or technologies he developed while
in our employ or for a two-year period following his termination.     

STOCK OPTION PLANS
    
     1998 STOCK OPTION PLAN

     Our 1998 stock option plan was established to provide directors, officers

No additional options will be granted under the 1998 stock option plan.

     1999 STOCK OPTION PLAN

     Our 1999 stock option plan is intended to provide directors, officers and

some other individuals as the board may determine. Generally, the board of
directors has discretion to amend, suspend or terminate the plan from time to

                            PRINCIPAL STOCKHOLDERS
    
     The following table presents, as of the date of this prospectus,

</TABLE>

_______________

     In calculating the information in this table, we relied on the following
assumptions:

     .    all the persons named in the table have sole voting and investment
          power over all shares they beneficially own, subject to community
          property laws, where applicable;

     .    a person or entity is considered the beneficial owner of securities
          that it can acquire through the exercise of options within 60 days
          from the date of this prospectus;

     .    In calculating each beneficial owner's percentage ownership we
          assumed that only options held by that person that are exercisable
          within 60 days of the date of this prospectus have been exercised.

     The shares beneficially owned by Kris Shah include (a) 435,301 shares held
by the Chandra L. Shah Trust, of which Mr. Shah is the trustee, (b) 435,301
shares held by the Leena Shah Trust, of which Mr. Shah is the trustee and (c)
2,349,877 shares held by the Kris and Geraldine Shah Family Trust, of which Mr.
Shah and his wife are the trustees and beneficiaries.

     The shares beneficially owned by Ramesh R. Shah and Patricia L. Shah are
held by the Ramesh R. Shah and Patricia L. Shah Living Trust, of which Ramesh R.
Shah and      

                                      -98-
<PAGE>
 
    
Patricia L. Shah are trustees and beneficiaries. Ramesh Shah is the brother of
Kris Shah and Patricia Shah is the sister-in-law of Kris Shah.

     The shares beneficially owned by Mr. Gray are shares issuable upon exercise
of his currently exercisable options.

     The shares beneficially owned by all directors and executive officers as a
group include 80,904 shares issuable upon exercise of currently exercisable
options and exclude 69,846 shares issuable upon exercise of options which become
exercisable at various times commencing December 31, 1999.  The inclusion of
shares in this table as beneficially owned is not an admission of beneficial
ownership.     


                             CERTAIN TRANSACTIONS

THE PULSAR ACQUISITION
    
     Litronic entered into a stock acquisition agreement with Pulsar and William
W. Davis, Sr., our president and chief operating officer, and Lillian Davis, the
former stockholders of Pulsar.  The agreement provides that Mr. Davis and Ms.
Davis will exchange all of their stock for an aggregate of 2,169,938 shares of
our common stock simultaneously with the closing of this offering.  The shares
of our common stock that Mr. Davis and Ms. Davis will receive are valued at
approximately $21.7 million, based on an assumed initial public offering price
of $10 per share.  As a result of the Pulsar acquisition, Pulsar will become a
wholly-owned subsidiary of our company and William Davis and Lillian Davis will
become principal stockholders of our company.

THE POTENTIAL ASSURE TECHNOLOGY ACQUISITION

     Creditors of Sistex, Inc., the current owner of the Assure technology, have
obtained judgments against Sistex aggregating approximately $6.0 million. As
a result, Sistex has turned over to a Commissioner in Chancery the Assure
technology for sale or other disposition.

     We intend to enter into an agreement with the judgment holders on or before
April 16, 1999 by which:

     .    the judgment holders will agree to postpone the foreclosure sale until
          after the closing of this offering so that we will have an opportunity
          to bid on and possibly acquire the technology, and

     .    in return, we will agree to make a minimum bid at the foreclosure sale
          of least $6.0 million, payable in unregistered shares of our common
          stock     

                                      -99-
<PAGE>
 
    
          valued at the average closing price of our common stock on Nasdaq on
          the five days prior to the day of the foreclosure sale.

Our decision to enter into this agreement will be subject to our being satisfied
with the results of our due diligence investigation relating to the Assure
technology, which investigation must be completed prior to April 16, 1999.

     Included among the judgment holders in the foreclosure action are
affiliates of BlueStone, who hold judgments aggregating approximately $750,000,
including a judgment in the amount of approximately $150,000 held by Anthony
Giraudo, a director nominee of our company and a limited partner of BlueStone.
If our bid is the winning bid at the foreclosure sale, all of the judgment
holders, including the BlueStone affiliates, will receive their proportionate
percentage of the shares of our common stock included in the bid.     

OTHER TRANSACTIONS WITH RELATED PARTIES
    
     We had obligations aggregating approximately $211,000 to Kris Shah, our
chief executive officer and chairman of the board, for accrued compensation at
December 31, 1994. On January 2, 1995, this obligation was converted into an
unsecured note, bearing interest at an annual rate of 8%, which was due on
December 31, 1998.  On October 29, 1997, the aggregate principal and interest
amounting to approximately $252,000 due on the note was repaid.     

     In 1996 and 1997, in the ordinary course of business, we have financed
equipment for our operations in the aggregate amount of approximately $1.5
million. These obligations were personally guaranteed by Kris Shah, and were
satisfied in full during 1997.   

     In June 1995, Davis Holding, Inc., a privately held corporation owned
entirely by the son of William W. Davis, Sr., purchased a building in Atlanta,
Georgia.  This purchase was financed through loans to Davis Holding, Inc. from
Wilmington Trust Company in the amount of $2.4 million.  These loans were
guaranteed by Pulsar and personally guaranteed by William W. Davis, Sr. and
Lillian Davis.

     Between July 1995 and June 1996, Pulsar made a series of eight loans
aggregating $2.8 million to Davis Holding, Inc.  These loans bear interest at
annual rates varying from 7.5% to 10.0% and are due on demand.  Two of these
loans were in the form of assignment of notes receivable to Pulsar from third
parties in the aggregate principal amount of $623,000, which were assigned back
to Pulsar in December 1997.  The notes were written off as bad debt expense in
the year ended December 31, 1997.

     In October 1995, Davis Holding, Inc. and Mr. Davis' son purchased Palmer
III Limited Partnership.  At the time of the purchase, the principal asset of
Palmer was a building in Lanham, Maryland.  This purchase was financed through a
loan to Davis Holding, Inc. from Wilmington Trust Company in the amount of $2.8
million which was guaranteed by Pulsar and personally guaranteed by William W.
Davis, Sr. and Lillian Davis.  Following the acquisition of the building, Davis
Holding, Inc. leased a portion of the Lanham, Maryland building to Pulsar 
at     

                                     -100-

fair market rate rents. Payments of rent under the lease were $1,042,000,
$955,500 and $409,500 during the years ended December 31, 1996, 1997 and 1998. A
portion of the rent expense incurred under the related party lease was used to
offset the notes receivable balance of the related party. The amount of rent
expense used to offset the notes receivables from Davis Holding, Inc. for the
years ended December 31, 1997 and 1998 was $182,000 and $344,000. In addition,
principal and interest under the notes were reduced by $750,000 as payment of a
fee for terminating the lease as of September 30, 1998. As of January 1, 1999,
the approximately $1.3 million outstanding under these loans was converted into
a $543,000 promissory note and a $804,000 promissory note, each bearing interest
at an annual rate of interest of 7.5%, payable monthly, and maturing upon the
sales of the Lanham, Maryland and Atlanta, Georgia properties. Previously, it
was anticipated that these sales would occur in 1999; however, the transactions
have been delayed for an unspecified period of time. Consequently, Pulsar can no
longer determine the recoverability of these notes and therefore reclassified
the notes as a reduction of stockholders' equity and fully reserved for them as
of December 31, 1998. The notes are being retained by Pulsar.

     In May 1996, Pulsar entered into a line of credit with Wilmington Trust
Company which was personally guaranteed by William W. Davis, Sr., and Lillian
Davis.  Under the line of credit, Pulsar could borrow up to the lesser of its
accounts receivable or $22 million secured by a pledge of eligible accounts
receivable, inventory, machinery and equipment.  Interest on the outstanding
line of credit accrues at a variable rate of interest.  In October 1997, the
line of credit was converted to a term loan of $5.20 million which is guaranteed
by William W. Davis, Sr., Lillian Davis, Palmer III Limited Partnership and
Davis Holding, Inc., and is secured by an indemnity mortgage and security deed
from Palmer III Limited Partnership on its Lanham, Maryland property and a
security deed from Davis Holding, Inc. on its Atlanta, Georgia property.     

     We had an unsecured revolving line of credit up to $1 million from Kris
Shah which accrued interest at an annual rate of 8%.  All unpaid principal and
interest under this line was repaid during 1996.  During the year ended December
31, 1996, $30,000 of the interest under this line was paid to Mr. Shah.  The
line of credit expired on January 31, 1997 and was not renewed.
    
     In June 1996, we entered into a one-year loan and security agreement with
Fidelity Funding, Inc., which was personally guaranteed by Kris Shah.  Under the
agreement, Fidelity extended a variable rate credit line of up to $5.95 million,
of which $1.0 million was collateralized by fixed assets, $2.2 million was
collateralized by real estate, $2.5 million was collateralized by accounts
receivable and inventory and $250,000 in the form of a standby line of credit.
In September 1997, we sold the building securing the $2.2 million real estate
line and repaid the line.  In March 1998, the $2.5 million revolving credit
facility was extended to February 2000.  As of December 31, 1998, $580,000 was
outstanding under this facility.  We intend to repay the outstanding
indebtedness under this credit facility out of the proceeds from this offering,
at which time Mr. Shah's guarantee will be released.     

     In December 1996, we entered into a line of credit at a fixed annual rate
of interest of 6.6% with the Bank of Yorba Linda for up to $1.04 million, which
was personally guaranteed by 

                                     -101-
<PAGE>
 
Kris Shah and his wife Geraldine Shah and secured by a pledge of their personal
assets. This line was repaid in June 1997.
    
     In January 1997, we formed KRDS, Inc. as a wholly owned subsidiary in
connection with the acquisition of real estate. In connection with the formation
of KRDS, Inc. we made a capital contribution in the amount of $8.5 million to
KRDS, Inc. Following the acquisition, KRDS leased to us at market a portion of
the property acquired to use in our former Intercon division. In December 1997,
we made a cash distribution of $9.5 million to our stockholders. Subsequently,
we distributed the capital stock and net assets of KRDS (discussed below) to our
stockholders. As a result of the KRDS distribution, we removed the property and
the corresponding mortgage and related liabilities from our consolidated balance
sheet. Following the distribution, we borrowed $2.9 million from KRDS which was
evidenced by an unsecured promissory note. In February 1998, we borrowed an
additional $600,000 from KRDS which borrowing was evidenced by an unsecured
promissory note. Each of these notes bore interest at an annual rate of 10% and
were paid in full in September 1998 with the proceeds of our loan from BYL Bank
Group.

     In October 1997, Pulsar entered into an inventory and working capital
financing agreement with IGFC which provides that Pulsar can finance purchases
of products through IGFC. As amended on February 2, 1999, the agreement provides
for a credit line up to the lesser of $8 million, a specified percentage of
Pulsar's eligible accounts receivable or a specified percentage of Pulsar's on-
hand inventory. The credit line is secured by substantially all Pulsar's assets
and personal assets of William W. Davis, Sr. and is personally guaranteed by Mr.
Davis and Lillian Davis. We intend to repay a portion of the indebtedness
outstanding under this financing agreement using proceeds from this offering, at
which time Mr. Davis' guarantee and the assets pledged by Mr. Davis will be
released.

     During the year ended December 31, 1997 we made pro rata distributions to
our stockholders of (a) $9.5 million in cash, (b) the rights to the contingent
payment relating to the sale of our Intercon division, (c) the rights to a 
gross-up payment for expected tax liability resulting from the gain on the sale
of our Intercon division and (d) the capital stock and net assets of KRDS ($8.5
million of cash).

     In September 1998, we executed two promissory notes aggregating $5.2
million in favor of BYL Bank Group at a fixed annual rate of interest of 6.6%.
Both notes were personally guaranteed by Kris Shah and secured by a pledge of
personal assets of Mr. Shah. We intend to use a portion of the proceeds of this
offering to repay the indebtedness under this loan, at which time Mr. Shah's
guarantee and the assets pledged by Mr. Shah will be released.

     Mr. Davis loaned to Pulsar $120,000 on November 23, 1998 and $222,000 on
January 5, 1999. These loans bear interest at the annual rate of 6% beginning
April 1, 1999.

                           DESCRIPTION OF SECURITIES

    
     Upon the closing of the offering, our authorized capital stock will consist
of 25,000,000 shares of common stock, $0.01 par value per share and 5,000,000
shares of preferred stock, $0.01 par value per share. As of the date of this
prospectus, there are 3,870,693 shares of our common stock held of record by
five stockholders, and, after giving effect to the Pulsar acquisition, there
will be 6,040,631 shares of our common stock outstanding held of record by seven
stockholders.

     We have summarized below selected provisions of Delaware law applicable to
our company, and the principal provisions of our common stock, our certificate
of incorporation and our bylaws. However, our descriptions are only a summary
and you should refer to the actual provisions of Delaware law, our certificate
of incorporation and our bylaws which we included as exhibits to the
registration statement, for a more complete explanation of their 
provisions.

COMMON STOCK

     Holders of our common stock are entitled to one vote for each share held on
all matters submitted to a vote of stockholders and do not have cumulative
voting rights. Therefore, holders of a majority of the shares of common stock
may elect all of the directors standing for election. Holders of common stock
are entitled to receive any dividends that are declared by the board of
directors. Upon our liquidation, dissolution or winding up, and after payment of
all debts and other liabilities holders of our common stock are entitled to
receive our remaining net assets. Holders of common stock have no preemptive,
subscription or redemption rights. The outstanding shares of common stock are,
and the shares we are offering in this offering will be when issued and paid
for, fully paid and non-assessable.

PREFERRED STOCK

     Our certificate of incorporation authorizes our board of directors to issue
up to 5,000,000 shares of preferred stock with a par value of $0.01 per share.
The board may issue the stock in one or more series and may fix the rights,
voting process and preferences of the stock. As of the date of this prospectus,
no shares of preferred stock have been issued.

REGISTRATION RIGHTS

     We have entered into a registration rights agreement with our stockholders
which grants our stockholders the right to include their shares in any
registration of our common stock in an underwritten offering that occurs after
this offering.  All of the stockholders have agreed not to exercise this right
for two years following the closing of this offering, without the prior written
consent of BlueStone.  We have also     

                                     -103-
<PAGE>
 
    
granted the representatives of the underwriters registration rights with respect
to their warrants to purchase up to 300,000 shares of our common stock.

DELAWARE LAW AND CHARTER AND BYLAW PROVISIONS LIMITING LIABILITY OF OFFICERS AND
DIRECTORS

     Section 203 of the General Corporation Law of Delaware generally prohibits
us from engaging in a merger, asset sale and other transaction with an
interested stockholder that results in a financial benefit to the interested
stockholder for a three year period from the date the person became an
interested stockholder. Generally, an interested stockholder is a person who,
together with affiliates and associates, owns, or within three years did own,
15% or more of our voting stock.

     Under Delaware General Corporation Law the affirmative vote of a majority
of the shares entitled to vote on any matter is required to amend our
certificate of incorporation or bylaws.

     Our certificate of incorporation contains provisions limiting the liability
of our directors. Specifically, the provisions eliminate a director's liability
for monetary damages for a breach of fiduciary duty, except in cases involving
wrongful acts, such as the breach of a director's duty of loyalty, or acts or
omissions which involve intentional misconduct or a knowing violation of law.
Further, our certificate of incorporation contains provisions to indemnify our
directors and officers to the fullest extent permitted by the Delaware General
Corporation Law. We believe these provisions will assist us in attracting and
retaining qualified individuals to serve as directors.

TRANSFER AGENT AND REGISTRAR

     The transfer agent and registrar for the common stock is Continental Stock
Transfer & Trust Company, Two Broadway, New York, New York 10004.


                        SHARES ELIGIBLE FOR FUTURE SALE

     An aggregate of 3,870,693 of the 6,040,631 shares currently restricted from
trading in the public market will become eligible for sale 90 days following the
date of this prospectus, subject to agreements with BlueStone restricting their
sale for periods of at least six months.  We cannot predict the effect, if any,
that sales of these additional securities or the availability of these
additional securities for sale will have on the market prices prevailing from
time to time.  In addition, the representatives have been granted registration
rights commencing one year from the date of this prospectus providing for the
registration under the Securities Act of the securities issuable upon exercise
of the representatives' warrants.  The exercise of these rights could result in
substantial expense to us.  Furthermore, if the representatives exercise their
registration rights, they will be     

                                     -104-
<PAGE>
 
    
unable to make a market in our securities for up to nine days before the initial
sales of the warrants until the discontinuation of sales. If the representatives
cease making a market, the market and market prices for the securities may be
adversely affected and the holders of these securities may be unable to sell
them.

     Upon completion of this offering, we will have outstanding an aggregate of
9,040,631 shares of our common stock, assuming no exercise of the
representatives' over-allotment option and no exercise of outstanding options.
Of these shares, all of the shares sold in this offering will be freely tradable
without restriction or further registration under the Securities Act, unless
these shares are purchased by our affiliates. The remaining 6,040,631 shares of
common stock held by existing stockholders are restricted securities under Rule
144 under the Securities Act. Restricted securities may be sold in the public
market only if registered or if they qualify for an exemption from registration
under Rules 144 or 701 under the Securities Act.

CONTRACTUAL RESTRICTIONS ON RESALES

     All of our officers, directors and security holders have agreed not to
transfer or dispose of, directly or indirectly, any of their shares of our
common stock, or any securities convertible into or, exchangeable or exercisable
for shares of our common stock, for a period of 24 months from the date of this
prospectus. Transfers or dispositions may be made sooner than 24 months as
follows:

 .    BlueStone may waive the restrictions on transfer or sale at any time more
     than six months after the date of this prospectus; or

 .    beginning twelve months after the date of this prospectus, owners subject
     to the restrictions may transfer or dispose of their common stock, without
     BlueStone's permission, if aggregate sales by them in any 90-day period are
     not more than the greater of :

     .    one percent of our common stock outstanding at the time of the sale;
          or

     .    the average weekly trading volume of our common stock during the four
          calendar weeks preceding the holder's sale.

     .

beginning 12 months after the date of this prospectus, existing optionholders
who have exercised their options may transfer or dispose of in the aggregate up
to 100,000 shares of their common stock registered under a Form S-8 registration
statement.

Subject to these contractual restrictions and to the provisions of Rule 144,
3,870,693 shares of common stock will be available for sale in the public market
commencing six months after the date of this prospectus, and an additional
2,169,938 shares of common stock will be available for sale in the public market

                                     -105-

     RULE 144

     In general, under Rule 144 as currently in effect, beginning 90 days after
the date of this prospectus, a person who has beneficially owned shares of our
common stock for at least one year would be entitled to sell, within any three-
month period, a number of those shares that does not exceed the greater of:

     .    one percent of the number of common shares then outstanding, which
          will equal approximately 90,400 shares immediately after this
          offering; or

     .    the average weekly trading volume in the common stock on the Nasdaq
          National Market during the four calendar weeks preceding the filing of
          a notice on Form 144 for the sale.

Sales under Rule 144 are also subject to restrictions on the manner of sale and
require notice to the Securities and Exchange Commission of the sale. Sales
under Rule 144 are also restricted based on the availability of public
information about us.

     RULE 144(K)

     Under Rule 144(k), a person who is not deemed to have been one of our
affiliates at any time during the 90 days preceding a sale, and who has
beneficially owned the shares proposed to be sold for at least two years,
including the holding period of any prior owner other than an affiliate, is
entitled to sell those shares without complying with the manner of sale, public
information, volume limitation or notice provisions of Rule 144.  Therefore,
unless otherwise restricted, 144(k) shares may be sold immediately upon the

with the holding period, information and volume restrictions contained in Rule
144.

                                 UNDERWRITING

     BlueStone Capital Partners, L.P. and Pacific Crest Securities Inc. are
acting as representatives of the several underwriters named below.  The
underwriters have agreed, severally and not jointly, subject to the terms and
conditions contained in the underwriting agreement relating to this offering, to
purchase the 3,000,000 shares of common stock offered by     

                                     -106-
<PAGE>
 
our company. The number of shares of common stock that each underwriter has
agreed to purchase is set forth opposite its name below:

    
Underwriter                         Number of Shares
- -----------                         ----------------
BlueStone Capital Partners, L.P.
Pacific Crest Securities Inc.
 
                                           ---------
                    Total                  3,000,000
                                           =========


     The underwriters are committed to purchase and pay for all of the shares of
common stock offered by this prospectus (other than shares offered through the
over-allotment option) if any shares are purchased. The obligations of the
underwriters under the underwriting agreement are subject to approval of legal
matters by counsel and to various other conditions.

     The representatives have advised us that the underwriters propose to offer
the shares of common stock to the public at the public offering price set forth
on the cover page of this prospectus. The underwriters may allow to dealers who
are members of the National Association of Securities Dealers, Inc. concessions,
not in excess of $ . per share, of which not in excess of $ . per share may be
reallowed to other dealers who are members of the NASD.

     We have granted to the representatives an option, exercisable not later
than 45 days after the date of this prospectus, to purchase up to 450,000
additional shares of our common stock at the public offering price set forth on
the cover page of this prospectus, less underwriting discounts and commissions.
The representatives may exercise this option only to cover over-allotments, if
any, made in connection with the sale of the shares of common stock offered by
this prospectus. If the representatives exercise the over-allotment in full, the
total price to public would be $   , the total underwriting discounts and
commissions would be $   and the total proceeds, before payment of the expenses
of this offering, to our company would be $   . We estimate the expenses of this
offering, including those payable to or on behalf of the representatives and/or
the underwriters described below, to be $2.2 million, or $2.3 million if the
representatives' over-allotment option is completely exercised.

     We have agreed to reimburse the representatives for their accountable out-
of-pocket expenses incurred in connection with this offering, up to a maximum
amount equal to 1-1/2% of the gross proceeds derived from the sale of the shares
offered by this prospectus, including shares sold, if any, as a result of the
exercise of all or part of the representatives' over-allotment option. We have
also agreed to pay all expenses in connection with qualifying the shares offered
under the laws of the states designated by the     

                                     -107-
<PAGE>
 
    
representatives, including expenses of counsel retained for this purpose by the
representatives.

     At the closing of this offering, we will sell to the representatives and
their designees, for an aggregate of $300, warrants to purchase up to 300,000
shares of our common stock. The representatives' warrants will be exercisable at
any time, in whole or in part, during the four-year period commencing one year
from the date of this prospectus, at an exercise price of $ per share, which is
165% of the public offering price per share. The representatives' warrants are
assignable or transferable only to the officers and partners of the
representatives or the underwriters or members of the selling group during the
one-year period following the date of this prospectus. During the exercise
period, the holders of the representatives' warrants will have the opportunity
to profit from a rise in the market price of the common stock, which will dilute
the interests of our stockholders. We expect that the representatives' warrants
will be exercised when we would, in all likelihood, be able to obtain any
capital we need on terms more favorable than those provided by the
representatives' warrants. Any profit realized by the representatives on the
sale of their warrants or the underlying shares of common stock may be deemed
additional underwriting compensation. The representatives's warrants contain a
cashless exercise provision. We have agreed that, upon the request of the
holders of a majority of the representatives's warrants, we will at our own
expense, on one occasion during the exercise period, register the
representatives' warrants and the shares of common stock underlying the
representatives' warrants under the Securities Act. We have also agreed to
include the representatives' warrants and all shares of common stock underlying
the warrants in any appropriate registration statement which we file under the
Securities Act during the seven years following the date of this prospectus.

     In connection with the acquisition of Pulsar, BlueStone has served as our
financial advisor and will receive a fee of $500,000 for these services upon
closing of this offering.

     All of our officers, directors and securityholders have agreed not to sell,
offer for sale, transfer, pledge or otherwise dispose of any of their shares of
our common stock, or securities convertible, exchangeable or exercisable for
shares of our common stock, for a period of 24 months from the date of this
prospectus, provided that, after the first six months of this period, this
restriction can be waived by BlueStone, in its sole discretion, and provided
further that, after the first 12 months of this period, sales may be made,
without BlueStone's consent, as long as the number of shares (or share
equivalents) sold by any of these holders does not exceed, during any 90-day
period, the greater of (a) 1% of the then outstanding shares of our common stock
and (b) the average weekly trading volume of our common stock during the four
calendar weeks preceding the holder's sale.

     The representatives have informed us that they do not expect sales of the
securities offered to discretionary accounts to exceed 3% of the shares offered
by this prospectus.     

                                     -108-

     We have agreed to indemnify the underwriters against certain civil
liabilities, including liabilities under the Securities Act.
    
     Before this offering there has been no public market for our common stock.
Accordingly, the initial public offering price of the common stock will be
determined by negotiation between us and the representatives and may not
necessarily be related to our asset value, net worth or other established
criteria of value. Factors to be considered in determining the price include our
financial condition and prospects, an assessment of our management, market
prices of similar securities of comparable publicly-traded companies, financial
and operating information of companies engaged in activities similar to those of
our company and the general condition of the securities market.

     In connection with this offering, the underwriters may engage in passive
market making transactions in the shares on Nasdaq in accordance with Rule 103
of Regulation M promulgated under the Exchange Act.

     In connection with this offering, the underwriters may purchase and sell
the common stock in the open market. These transactions may include over-
allotment and stabilizing transactions. Stabilizing transactions consist of bids
or purchases for the purpose of preventing or retarding a decline in the market
price of the common stock. The underwriters may also place bids or purchase
shares to reduce a short position created in connection with the offering. Short
positions are created by persons who sell shares which they do not own in
anticipation of purchasing shares at a lower price in the market to deliver in
connection with the earlier sale. Short positions tend to place downward
pressure on the market price of a stock. In addition, the representatives and/or
the underwriters may impose a penalty bid by reclaiming the selling concession
to be paid to an underwriter or selected dealer when the securities sold by the
underwriter or selected dealer are purchased to reduce a short position created
in connection with this offering. These activities may stabilize, maintain or
otherwise affect the market price of the common stock, which may be higher than
the price that might otherwise prevail in the open market, and these activities,
if commenced, may be discontinued at any time. These transactions may be
effected on Nasdaq, the over-the-counter market or otherwise.

     Anthony Giraudo, a director nominee of our company, is a limited partner of
BlueStone.

in reliance upon the report of Keller Bruner & Company, L.L.C., independent
certified public accountants, appearing elsewhere herein, and upon the authority
of Keller Bruner & Company, L.L.C. as experts in accounting and auditing. The
report of Keller Bruner & Company, L.L.C. covering the December 31, 1997,
financial statements contains an explanatory paragraph that states that Pulsar's
recurring losses from operations and net capital deficiency raise substantial
doubt about the entity's ability to continue as a going concern. The financial
statements do not include any adjustments that might result from the outcome of
that uncertainty.

FINANCIAL STATEMENTS HAS BEEN CONSUMMATED, WE WILL BE IN A POSITION TO RENDER
THE FOLLOWING OPINION.)


    
                                            /s/ KPMG LLP     


The Board of Directors
Litronic Inc.:

We have audited the accompanying consolidated financial statements of Litronic
Inc. and subsidiary as of December 31, 1997 and 1998 and for each of the years
in the three-year period ended December 31, 1998 as listed in the accompanying
index.  These consolidated financial statements are the responsibility of the
Company's management.  Our responsibility is to express an opinion on these
consolidated 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 consolidated financial statements referred to above present
fairly, in all material respects, the financial position of Litronic Inc. and
subsidiary as of December 31, 1997 and 1998 and the results of their operations
and their cash flows for each of the years in the three-year period ended
December 31, 1998, in conformity with generally accepted accounting principles.

                  Notes to Consolidated Financial Statements

                     (in thousands, except per share data)

(1)  GENERAL INFORMATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     GENERAL

     Litronic Inc. (through a reorganization with Litronic Industries, Inc., as
     described further below) (the Company) designs and produces high grade
     information security solutions.  In addition, the Company also provides
     engineering and other services to various government agencies on a time and
     material basis.  Through its Intercon division (Intercon), which was
     discontinued during 1997 (see note 2), Litronic Industries, Inc. provided
     state-of-the-art electronic interconnect products for both government and
     commercial entities.

     PROPOSED PUBLIC OFFERING AND REORGANIZATION

     During 1998, Litronic Industries, Inc. engaged attorneys and investment
     bankers to assist in the effectuation of an initial public offering of
     common stock of Litronic Inc., a newly formed corporation with no
     operations (the "Offering").  Litronic Industries, Inc. has also initiated
     certain events (the "Reorganization") in connection with the Offering which
     will result in it becoming a wholly-owned subsidiary of Litronic Inc.  as
     of the effective date of the Offering. The Reorganization will be
     accomplished through a stock-for-stock exchange between Litronic Inc. and
     Litronic Industries, Inc. and will be accounted for as an "as if pooling of
     interests" for entities under common control.  The Company has also entered
     into a plan of merger with Pulsar Data Systems, Inc. to be effected
     simultaneously with the Offering.  This merger is contingent upon the
     successful completion of the Offering.

     All of the outstanding shares of Litronic Industries, Inc. will be
     exchanged for 3,870,693 shares of the Company's common stock.
     Consequently, upon the effective date of the Offering and the related
     Reorganization, the consolidated group will include the operations of
     Litronic Inc. and its wholly-owned subsidiary, Litronic Industries, Inc.

     BASIS OF FINANCIAL STATEMENT PRESENTATION

     The consolidated financial statements and related notes presented herein
     have been retroactively adjusted to reflect the Reorganization.  The
     capital structure presented in these financial statements is that of
     Litronic Inc., but all other information presented relates to the
     historical and pro forma operations of Litronic Industries, Inc., as
     Litronic Inc. had no operations during the periods presented and will have
     no operations until the consummation of the Reorganization.  All references
     herein to "the Company" refer to Litronic Inc. as consolidated with
     Litronic Industries, Inc.

                                AND SUBSIDIARY

            Notes to Consolidated Financial Statements (continued)


     Concurrently with the Reorganization, Litronic Industries, Inc. will
     terminate its Subchapter S corporation status and will become subject to
     federal and state income taxes.  The accompanying pro forma consolidated
     balance sheet reflects this change from an S corporation to a C
     corporation.  The accompanying pro forma consolidated financial statements
     of operations include a pro forma presentation to reflect a provision for
     income taxes in accordance with Statement of Financial Accounting Standards
     No. (Statement) 109, "Accounting for Income Taxes." Statement 109 is an
     asset and liability approach that requires the recognition of deferred tax
     assets and liabilities for the expected future tax consequences of events
     that have been recognized in the Company's financial statements or tax
     returns. Measurement of deferred income tax is based on enacted tax laws
     including tax rates, with the measurement of deferred income tax assets
     being reduced by available tax benefits not expected to be realized.  The
     Company has not recorded any deferred tax assets in the accompanying
     unaudited consolidated pro forma balance sheet as management believes it is
     not more likely than not that the Company will realize the benefit of such
     deferred tax assets.

     Unaudited pro forma earnings (loss) for the years ended December 31, 1996,
     1997 and 1998 reflect a provision for (benefit from) income taxes as if the
     Company had been subject to federal and state income taxes at an estimated
     effective tax rate of approximately 34%.

     PRO FORMA EARNINGS (LOSS) PER SHARE

     In 1997, the Financial Accounting Standards Board issued Statement 128,
     "Earnings Per Share."  Statement 128 provides for the calculation of basic
     and diluted earnings per share. Basic earnings per share includes no
     dilution and is computed by dividing earnings (loss) available to common
     shareholders by the weighted average number of common shares outstanding
     for the period.  Diluted earnings per share reflects the potential dilution
     of securities that could share in the earnings of an entity.  Such shares
     are not included when there is a loss as the effect would be anti-dilutive.

     PRINCIPLES OF CONSOLIDATION

     The consolidated financial statements include the accounts of Litronic
     Inc., its wholly-owned subsidiary Litronic Industries, Inc. and, in 1997,
     Litronic Industries, Inc.'s wholly owned subsidiary, KRDS, Inc., which was
     formed as a corporation on January 30, 1997.  All significant intercompany
     balances and transactions have been eliminated in consolidation. On
     December 31, 1997, the Company distributed KRDS, Inc. to the Company's
     primary shareholders (note 7).

     REVENUE RECOGNITION

     Revenue from product sales, including embedded software, is recognized upon
     shipment unless contract terms call for a later date, net of an allowance
     to cover estimated warranty costs.  Customers do not have the right of
     return except for product defects, and product sales are not contingent
     upon customer testing, approval and/or acceptance.  The costs of providing

            Notes to Consolidated Financial Statements (continued)


     postcontract customer support are not significant. Revenue under service
     and development contracts is recorded as services are rendered. The
     Company's revenue recognition policies are in compliance with the American
     Institute of Certified Public Accountants Statement of Position 97-2,
     Software Revenue Recognition. Reimbursements under consortium agreements
     were recorded as revenue as they became payable to the Company upon
     completion of related milestones.

     Included in license and service revenue in 1998 is $398 related to a
     contract with a branch of the Federal government, whereby the Company is
     being partially reimbursed for certain research and development efforts.
     The related research and development costs are not separately
     identifiable, therefore the corresponding costs of the entire development
     effort are included in research and development expenses.

     INVENTORIES

     Inventories are stated at the lower of cost (first-in, first-out) or market
     (net realizable value).

     PROPERTY AND EQUIPMENT

     Property and equipment are stated at cost.  Depreciation of property and
     equipment is computed on a straight-line basis over the estimated useful
     lives of 2 to 7 years.

     Long-lived assets and certain identifiable intangibles are reviewed for
     impairment whenever events or changes in circumstances indicate that the
     carrying amount of an asset may not be recoverable.  Recoverability of
     assets to be held and used is measured by comparison of the carrying amount
     of an asset to future net cash flows expected to be generated by the asset.
     If such assets are considered to be impaired, the impairment to be
     recognized is measured by the amount by which the carrying amount of the
     assets exceed the fair value of the assets. Assets to be disposed of are
     reported at the lower of the carrying amount or fair value less costs to
     sell.

     BUSINESS SEGMENTS

     As of January 1, 1998, the Company adopted Statement 131, "Disclosure about
     Segments of an Enterprise and Related Information," which requires entities
     to report financial and descriptive information about its reportable
     operating segments. The Company historically operated in two business
     segments, information security solutions and electronic interconnect
     products. On September 30, 1997, the Company sold its Intercon division,
     which produced electronic interconnect products. Accordingly, the Intercon
     division operations have been accounted for as discontinued operations
     (note 2). The Company's remaining operations pertain only to its
     information security solutions segment.


     ACCOUNTING FOR STOCK OPTIONS

            Notes to Consolidated Financial Statements (continued)


     The Company applies the provisions of Statement 123, "Accounting for Stock-
     Based Compensation," which requires entities to recognize as expense over
     the vesting period the fair value as of the date of grant of all stock
     based awards. Alternatively, Statement 123 allows entities to apply the
     provisions of Accounting Principles Board (APB) Opinion No. 25, "Accounting
     for Stock Issued to Employees," and related interpretations, and to provide
     pro forma net income and pro forma net income per share disclosures for
     employee stock option grants made in 1996 and future years as if the fair-
     value-based method defined in Statement 123 had been applied. The Company
     has elected to apply the provisions of APB Opinion No. 25, under which
     compensation expense would be recorded on the date of grant only if the
     current market price of the underlying stock exceeded the exercise price,
     and provide the pro forma disclosure provisions of Statement 123 in its
     annual financial statements (see note 10).

     FAIR VALUE OF FINANCIAL INSTRUMENTS

     The Company applies the provisions of Statement 107, "Disclosures about
     Fair Value of Financial Instruments." Statement 107 requires all entities
     to disclose the fair value of financial instruments, both assets and
     liabilities recognized and not recognized on the balance sheet, for which
     it is practicable to estimate fair value.  Statement 107 defines fair value
     of a financial instrument as the amount at which the instrument could be
     exchanged in a current transaction between willing parties.  As of December
     31, 1997 and 1998, management believes the fair value of all financial
     instruments approximated carrying value.

     INCOME TAXES

     The Company has elected to be taxed as an S Corporation under the
     provisions of Section 1362 of the Internal Revenue Code and uses the
     accrual basis of reporting for income tax purposes.  Accordingly, the
     Company has not provided for Federal income taxes since the liability is
     that of the shareholders.  The Company is subject to state income taxes on
     earnings before taxes.  The provision (benefit) for state income taxes was
     $29 for continuing operations and $(13) for discontinued operations for the
     year ended December 31, 1996.  The provision (benefit) for state income
     taxes was $22 for continuing operations, $(23) for discontinued operations,
     and $241 for the gain on disposal of discontinued operations for the year
     ended December 31, 1997.  The benefit for state income taxes was $95 for
     continuing operations for the year ended December 31, 1998.

     COMPREHENSIVE INCOME

     As of January 1, 1998, the Company adopted Statement 130, "Reporting
     Comprehensive Income." Statement 130 establishes new rules for the
     reporting and display of comprehensive income and its components; however,
     the adoption of Statement 130 had no impact on the Company's consolidated
     financial statements as the Company had no transactions that would be
     considered other comprehensive income.

            Notes to Consolidated Financial Statements (continued)


     The consolidated financial statements have been prepared in conformity with
     generally accepted accounting principles.  In preparing the consolidated
     financial statements, management is required to make estimates and
     assumptions that affect the reported amounts of assets and liabilities as
     of the dates of the balance sheets and revenues and expenses for the
     periods.  Actual results could differ from those estimates.

     NEW ACCOUNTING STANDARDS

     In December 1998, the AICPA issued Statement of Position (SOP) 98-9.  SOP
     98-9 amends certain paragraphs of SOP 97-2 to require recognition of
     revenue using the "residual method" under certain circumstances.  The
     "residual method" established by SOP 98-9 is effective for fiscal years
     beginning after March 15, 1999.  The Company believes the adoption of SOP
     98-9 will not have a significant impact on its financial position or
     results of operations.

(2)  DISCONTINUED OPERATIONS

     The Company sold its Intercon division on September 30, 1997 for cash to
     AlliedSignal Inc., a non-related publicly-traded company.  The gain on sale
     was $15,023, net of tax expense of $241.  The results of the Intercon
     division have been classified as discontinued operations in the
     accompanying consolidated financial statements.  For the year ended
     December 31, 1996, Intercon revenues were $8,175.  Intercon's 1997 revenues
     through the sale date were $7,653.

     In addition to the cash proceeds received upon the close of the
     transaction, the agreement provided for the right to receive a contingent
     purchase price as well as a "gross-up" payment based upon the approximate
     expected tax benefit related to the assets transferred. Effective November
     30, 1997, this right was distributed pro rata to the Company's
     shareholders.

     On December 31, 1997, the Company spun-off its subsidiary, KRDS, Inc., to
     the Company's shareholders.  The results of KRDS, Inc. have been classified
     as discontinued operations in the accompanying consolidated financial
     statements.  For the year ended December 31, 1997, KRDS, Inc.'s revenues
     were $380.

covenants, and has received a waiver of these covenants until April 1, 1999.  
In addition, the Revolver was amended through the earlier of the closing of the 
Offering or May 31, 1999.     

As of December 31, 1998, the Company had available borrowings of $1,920 under
the Revolver.

(7)  RELATED PARTY TRANSACTIONS

     At December 31, 1994, the Company had an obligation of $248 to two of the
     Company's executive officers for accrued compensation.  On January 2, 1995,
     such obligation was converted to two unsecured notes payable bearing
     interest at 8%, which were due and payable on December 31, 1998.  On
     October 29, 1997, the principal and interest amounting to $305 due on the
     notes was repaid.  The Company incurred interest expense on these notes
     aggregating $20 and $18 in 1996 and 1997, respectively.

     The Company had an unsecured revolving line of credit with the Company's
     president and majority shareholder, which permitted borrowings of up to
     $1,000.  All unpaid principal and accrued interest at 8% per annum were due
     and payable on January 31, 1997.  The Company incurred interest expense
     under this line of credit aggregating $30 in 1996.  All outstanding
     borrowings and accrued interest under this line of credit were repaid
     during 1996.  The line was not renewed when it expired on January 31, 1997.

     The primary shareholders of Litronic Industries, Inc. formed KRDS, Inc.,
     for the sole purpose of purchasing real estate property.  The majority of
     the property acquired was leased to the Intercon division and the acquirer
     of the Intercon division has subsequently executed a continuing lease
     arrangement with KRDS, Inc. KRDS's only operations consisted of a mortgage
     obligation, interest, depreciation and rental income from the Company
     related to the real estate property.  The operations of KRDS, Inc. were
     consolidated with the operations of Litronic Industries, Inc. through
     December 31, 1997, when concurrent with the sale of the Intercon division,
     the Company distributed KRDS, Inc. to the Company's shareholders.  As the
     operations of KRDS, Inc. were related to the Intercon operations, the 1997
     net income for

            Notes to Consolidated Financial Statements (continued)

     KRDS, Inc. of $2 (after intercompany eliminations) is included in the loss
     from discontinued operations in the accompanying consolidated statement of
     operations.

     As a result of the sale of the Intercon division on September 30, 1997, the
     Company distributed $9,534 in cash dividends and distributed the common
     stock of KRDS, Inc., to the shareholders of Litronic on a pro rata basis in
     1997. The net assets of KRDS, Inc. consisted of $8,500 in cash at the time
     of the distribution.

     On December 31, 1997, the Company entered into two unsecured notes payable
     with KRDS, Inc., it is which the Company was extended $900 and $2,000 in
     working capital funds and a total of $2,900 was outstanding under these
     related party notes at December 31, 1997. In February 1998, the Company
     entered into a third unsecured note payable with KRDS, Inc., under which
     the Company was extended $600 in working capital funds. Interest was at 10%
     for each of the unsecured notes payable and each of these unsecured notes
     and accrued interest were paid in full during 1998. The Company incurred
     $252 of interest expense on these notes in 1998.

(8)  CONCENTRATION OF CREDIT RISK AND SIGNIFICANT CUSTOMERS

     Financial instruments that potentially subject the Company to concentration
     of credit risk are trade receivables. Credit risk on trade receivables is
     limited as a result of the Company's customer base and their dispersion
     across different industries and geographic regions. As of December 31, 1997
     and 1998, accounts receivable included $447 and $308, respectively, due
     from the U.S. Government and related agencies.

     The Company had sales to three customers which represented 39%, 29% and 18%
     of 1996 total revenue, respectively. The Company had sales to three
     customers which represented 45%, 20% and 19% of 1997 total revenue,
     respectively. The Company had sales to three customers which represented
     44%, 17% and 20% of 1998 total revenues, respectively. No other customers
     accounted for more than 10% of net revenues in 1996, 1997 or 1998. Trade
     accounts receivable aggregated $709 and $493 from the aforementioned major
     customers as of December 31, 1997 and 1998, respectively.

(9)  COMMITMENTS AND CONTINGENCIES

     The Company leases office space under noncancelable operating leases. The
     terms of the leases range up to four years. The following summarizes the
     future minimum lease payments under all noncancelable operating lease

     Rental expense under noncancelable operating leases was $206, $215 and $310
     for the years ended December 31, 1996, 1997 and 1998.

     As the Company provides engineering and other services to various
     government agencies, it is subject to retrospective audits which may
     result in adjustments to amounts recognized as revenues, and the Company
     may be subject to investigation by governmental entities. Failure to comply
     with the terms of any governmental contracts could result in civil and
     criminal fines and penalties, as well as suspension from future government
     contracts. The Company is not aware of any adjustments, fines or penalties
     which could have a material adverse effect on its financial position or
     results of operations.

(10) STOCK OPTION PLANS

     Under the Company's Employee Stock Option Plan (the Plan), which was
     established in April 1998, the exercise price of options granted will not
     be less than the fair market value of the related common stock at the date
     of grant. The total number of shares of common stock available for grant
     under the Plan is 600. All stock options granted have 10 year terms. Unless
     otherwise provided by the Board of Directors or a committee of the Board
     administering the Plan, each option granted under the Plan vested on
     December 31, 1998 as to 10-15%, plus an additional 2.5% for each year of
     service with the Company, and 20% each December 31 thereafter until fully
     vested.

     Following is a summary of stock option transactions:

            Notes to Consolidated Financial Statements (continued)
    
     As of December 31, 1998, the number of options exercisable was 143.     

     The Company applies APB Opinion No. 25 and related interpretations in
     accounting for its stock option plans.  Accordingly, no compensation cost
     has been recognized for its stock options in the consolidated financial
     statements.  Had the Company determined compensation cost based on the fair
     value at the grant date for its stock options under Statement 123, the
     Company's net loss would have been increased to the pro forma amount
     indicated below.

</TABLE>     

     The fair value of each option grant was estimated on the date of grant
     using the Black-Scholes option-pricing model with the following
     assumptions: risk-free interest rate of 5%; dividend yield of 0.0%; average
     expected lives of 6 years; and volatility of 0%. The weighted-average fair
     value per option granted in 1998 was $0.70. The Black-Scholes model, as
     well as other currently accepted option valuation models, was developed to
     estimate the fair value of freely-tradable, fully-transferable options
     without vesting restrictions, which significantly differ from the Company's
     stock option plans. These models also require highly subjective
     assumptions, including future stock price volatility and expected time
     until exercise, which greatly affect the calculated fair value on the grant
     date.

(11) EMPLOYEE RETIREMENT SAVINGS PLAN

     Effective January 1, 1998, the Company established a retirement plan, which
     is intended to qualify under Section 401(k) of the Internal Revenue Code.
     Under the plan, eligible employees are able to contribute up to 20% of
     their compensation not to exceed the maximum IRS deferral amount. The
     Company may also match employee contributions at its discretion. During
     1998, the Company made contributions of $40 to this plan.

                          INDEPENDENT AUDITORS' REPORT


The Board of Directors
Pulsar Data Systems, Inc.

We have audited the accompanying balance sheet of Pulsar Data Systems, Inc. as
of December 31, 1998 and the related statements of operations, stockholders'
equity (deficit) and cash flows for the year then ended.  In connection with our
audit of the financial statements, we also have audited the financial statement
schedule for the year ended December 31,1998 as listed in the accompanying
index.  These financial statements and financial statement schedule are the
responsibility of the Company's management.  Our responsibility is to express an
opinion on these financial statements and financial statement schedule based on
our audit.

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

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Pulsar Data Systems, Inc. as of
December 31, 1998, and the results of its operations and its cash flow for the
year ended December 31, 1998, in conformity with generally accepted accounting
principles.  Also in our opinion, the related financial statement schedule, when
considered in relation to the basic financial statements take as a whole,
presents fairly, in all materials respects, the information set forth therein.

The accompanying financial statements and financial statement schedule have been
prepared assuming that the Company will continue as a going concern.  As
discussed in Note 14 to the financial statements, the Company has suffered a net
loss of $7,396,000 in 1998 and has a net capital deficiency of $10,494,000 that
raise substantial doubt about its ability to continue as a going concern.
Management's plans in regard to these matters are also described in Note 14.
The financial statements and financial statement schedules do not include any
adjustments that might result from the outcome of this uncertainty.

To the Board of Directors
Pulsar Data Systems, Inc.
Lanham, Maryland

We have audited the accompanying balance sheet of Pulsar Data Systems, Inc. as
of December 31, 1997, and the related statements of operations, stockholders'
deficit, and cash flows for each of the years in the two year period ended
December 31, 1997 and the financial statement schedule for each of years in the
two year period ended December 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 Pulsar Data Systems, Inc. as of
December 31, 1997, and the results of its operations and its cash flows for each
of the years in the two year period ended December 31, 1997 in conformity with
generally accepted accounting principles.  Also in our opinion the related
financial statement schedule, when considered in relation to the basic financial
statements taken as a whole, present fairly in all material respects, the
information set forth therein.

The accompanying financial statements have been prepared assuming that the
Company will continue as a going concern. As discussed in note 14 to the
financial statements, the Company incurred a net loss of approximately
$11,016,000 during the year ended December 31, 1997 and has a net capital
deficiency of approximately $1,810,000 at December 31, 1997. In addition, as of
December 31, 1997, the Company is in violation of its financing agreement debt
covenants. These factors, among others, as discussed in Note 14 to the financial
statements, raise substantial doubt about the Company's ability to continue as a
going concern. The financial statements do not include any adjustments that
might result from the outcome of this uncertainty.

NOTE 1.   NATURE OF BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES

Nature of business:  Pulsar Data Systems, Inc. (the Company) was incorporated in
- ------------------                                                              
1984 under the laws of the State of Delaware. The Company is engaged primarily
in the sale of computer hardware, software, peripheral equipment, and support
services to governmental agencies and commercial enterprises throughout the
United States. The Company was certified by the Small Business Administration
under Section 8(a) of the Small Business Act and was therefore eligible to enter
into contracts with agencies of the Federal Government on a limited competitive
basis. The Company voluntarily withdrew in anticipation of graduation from the
8(a) program in June 1997.

A summary of the Company's significant accounting policies follows:

Revenue and cost recognition:  Revenue is primarily derived from short-term
- ----------------------------                                               
firm-fixed price delivery order type contracts.  Revenue from these contracts is
recognized upon transfer of title, generally upon delivery. The Company also has
time and material contracts. Revenue from time and material contracts is
recognized on the basis of man-hours provided plus other reimbursable contract
costs incurred during the period.

Cash and cash equivalents:  For the purpose of reporting cash flows, the Company
- -------------------------                                                       
considers all highly-liquid investments purchased with a maturity of three
months or less to be cash equivalents.

Inventory:  Inventory consists primarily of computer hardware, purchased
- ---------                                                               
software and peripheral equipment.  Inventory is stated at the lower of cost or
market using the first-in, first-out (FIFO) method.

Property and equipment:  Property and equipment are stated at cost.
- ----------------------   
Depreciation and amortization is computed using straight-line and accelerated
methods over the estimated useful lives of the related assets.

Income taxes: The Company has elected to be treated as an "S" Corporation under
- ------------                                                                   
Subchapter "S" of the Internal Revenue Code. Consequently, the Company is not
liable for Federal and state income taxes except to the extent that the Company
operates in state jurisdictions that do not recognize "S" corporations. For the
income related to activity in these states, the Company has provided for the
resulting income taxes. Otherwise the stockholders are liable individually for
income taxes on the Company's income.

NOTE 1.   NATURE OF BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES (Continued)

Financial credit risk: The Company's accounts receivable are derived primarily
- ---------------------                                                         
from contracts with governmental agencies and commercial enterprises.  All
accounts receivable are made on an unsecured basis.

Additionally, the Company maintains its cash in bank deposit accounts, which at
times may exceed Federally insured limits. The Company has not experienced any
losses in such accounts. The Company believes it is not exposed to any
significant credit risk on cash.

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

NOTE 4.   DEFERRED COMPENSATION AND LIFE INSURANCE

Through December 31, 1996 the Company had a deferred compensation agreement with
its President, which was funded through Company-owned life insurance policies.
The cash surrender value of these policies as of December 31, 1997 and 1998, was
$1,416,000 and $216,000, respectively. 

On December 31, 1997, the deferred compensation liability of $1,351,000 was
forgiven by the President of the Company, and the liability was removed from the
Company's balance sheet and included as a contribution to additional paid-in
capital. In April 1998, the Company borrowed $1,494,000 against the cash
surrender value of the life insurance policies to reduce amounts owed under the
financing arrangement with IBM.

NOTE. 5.  NOTES RECEIVABLE - RELATED PARTIES

Between July 1995 and June 1996, the Company made a series of eight loans
aggregating $2.8 million to a related party.  These loans bear interest at
annual rates varying from 7.5% to 10.0% and were due on demand.  Two of these
loans were in the form of assignment of notes receivable to the Company from
third parties in the aggregate principal amount of $623,000, which were assigned
back to Pulsar in December 1997. At that time these notes were deemed
uncollectible and written off to bad debt expense. The outstanding balance of
these notes as of December 31, 1997 was $2,218,000.
    
In October 1995, a related party purchased the building to be occupied by the
Company.  This purchase was financed through a loan to the related party from a
lending institution in the amount of $2.8 million, which was guaranteed by the
Company and personally guaranteed by the shareholders of the Company.  Following
the acquisition of the building, the related party leased a portion of the
property to the Company at fair market rents.  Payments of rent under the lease
were $1,042,000, $955,500 and $409,500 during the years ended December 31, 1996,
1997 and 1998, respectively.  A portion of the rent expense incurred under the
related party lease was used to offset the related party notes receivable
balance.  The amount of rent expense used to offset the notes receivable from
the related party for the years ended December 31, 1996, 1997 and 1998 was $0,
$182,000 and $344,000, respectively.  In addition, the principal amount under
the notes was reduced by $750,000 as payment of a fee for terminating the lease
as of September 30, 1998. As of January 1, 1999, outstanding loans of $1,347,000
were converted into two promissory notes of $543,000 and $804,000, bearing
interest at the rate of 7.5% per annum, payable monthly, and maturing upon the
sales of each individual property. The face amount of these notes includes
accrued interest of $149,000 which has not been reflected within the financial
statements. Because of the relationship to the related party and the change in
the terms of the notes receivable the notes have been classified as a component
of stockholders equity as of December 31, 1998.     

The Company had expected the collateral underlying the notes receivable from
related party to be liquidated. The Company has been advised that this
transaction is being delayed for an unspecified period of time. As the
recoverability of the notes is dependent upon the liquidation of the collateral,
the Company is unable to determine the recoverability of the notes receivable

and has established an allowance for the full amount of the notes as of December
31, 1998.

NOTE 6.   LINE OF CREDIT

In May 1996, the Company obtained a line of credit from a financial institution.
Under the line of credit, the Company may borrow up to the lessor of eligible
receivables or $22,000,000. Interest accrued on the outstanding balance at a
variable rate consistent with the bank's national commercial rate. The line is
collateralized by all eligible accounts receivable, inventory, machinery, and
equipment. In October 1997, the line of credit was converted to a term loan of
$5,200,000. (See Note 8)

NOTE 7.   FINANCING ARRANGEMENT - IBM

The Company entered into an Inventory and Working Capital Financing Agreement,
with IBM Global Finance Corporation (IBM) whereby the Company purchases,
hardware and software from authorized suppliers and finances the purchases
through IBM. The agreement provides for a credit line up to $35,000,000, which
allows the Company to borrow up to 85% of the Company's eligible accounts
receivable, and up to 100% of the Company's on-hand inventory. The credit line
is secured by substantially all assets of the Company and is personally
guaranteed by the Company's stockholders.

At December 31, 1997 the interest rate on the line of credit was prime plus
1.75% or 2.00% depending on the nature of the borrowings. The effective interest
rate at that date was 10.25% or 10.5%. Effective February 1, 1998, the financing
agreement interest rate was increased to prime plus 2.375%. The effective
interest rate at December 31, 1998 was 10.125%. For any amount that the
outstanding advances exceed the formula borrowing base, interest was accrued at
the rate of prime plus 6.5%.

The agreement provides for certain financial covenants to be met by the Company.
At December 31, 1998 the Company was in violation of these covenants.

In August 1997, the Company was in violation of the related debt covenants and
entered into a forbearance agreement with IBM. Subsequently the Company violated
the forbearance agreement and received several amendments to the agreement.
Pursuant to amendments of the forbearance agreement the Company is currently
obligated to pay, at the Company's option, the lesser of: (i) warrants
representing 4% of the Company on a fully diluted to basis, or (ii) pay
$650,000, or (iii) pay a pro rata portion of the $650,000 is less than
substantially all of the assets are sold. As the Company intends to pay
$650,000, the Company has accrued this amount as of December 31, 1997. In
further consideration of the forbearance agreement and the related amendments,
the Company was obligated to pay $50,000 or issue warrants representing 0.5% of
the Company on a fully diluted basis, per month from February through May, 1998.
The Company has paid an aggregate of $200,000 which has been recorded as
additional interest expense in 1998. These payments were made in lieu of the
issuance of warrants to IBM.

An October 1998 amendment to the forbearance agreement decreased the credit line
to $18,000,000 for the period through January 6, 1999, at which time the line
will be further reduced to $15,000,000. The financing arrangement has a
termination date of October 30, 1999.

A February 1999 amendment to the forbearance agreement decreased the credit line
to $8,000,000 until further amended. A March 1999 amendment to the forbearance
agreement increased the credit line to $9,000,000 for the period through April
30, 1999, at which time the line will be reduced to $8,000,000. The forbearance
agreement expires on the anticipated merger and initial public offering (Note
14).

$10,494,000 at December 31, 1997 and 1998, respectively. At December 31, 1998,
the Company is in violation of the financial covenants related to its financing
agreement. These factors create a substantial doubt about the Company's ability
to continue as a going concern. The Company is in negotiations to be acquired by
another company. The combined company is in the process of preparing an initial
public offering. The ability of the Company to continue as a going concern is
dependent upon the success of the pending merger and initial public offering.
The financial statements do not include any adjustments that might be necessary
if the Company is unable to continue as a going concern.


NOTE 15.  CONTINGENT LIABILITIES

The Company had cost reimbursable type contracts with the Federal Government.
Consequently, the Company is reimbursed based upon their direct expenses
attributable to the contract, plus a percentage based upon overhead, material
handling, and general and administrative expenses. The overhead, material
handling, and general and administrative rates are estimates. Accordingly, if
the actual rates as determined by the Defense Contract Audit Agency are below
the Company's estimates, a refund for the difference would be due to the Federal
Government. It is management's opinion that no material liability will result
from any cognizant audit agency audits.

The Company is subject to several lawsuits and threatened actions relating to
the non-payment of debts. Each of these amounts have been included as
liabilities in the financial statements.

The Company has been named as a defendant in a lawsuit which claims breach of
contract under which the Company was required to pay $500,000 over a thirty
month period plus a commission on contracts awarded as a result of the contract.
The plaintiff claims damages in an amount in excess of $10 million. Based upon
discussions with counsel, the Company believes that the case is without merit
and intends to vigorously defend against the claim; however, the outcome of this
matter cannot currently be determined. No amounts have been accrued in the
financial statements relating to this matter.

The Company is also involved in various routine legal actions arising in the
normal course of business. After taking into consideration legal counsel's
evaluation of such actions, management is of the opinion that any potential
liability, arising from these claims against the Company not covered by
insurance would be minimal.

The Company has guaranteed the mortgages on properties owned by a related party
of approximately $5,100,000. Should the related party fail to perform under the
terms of the agreement, the Company would incur a loss for the full amount of
the guarantee. 

As of March 31, 1999, the Company had not yet filed the Form 5500 Annual
Return/Report for 1997 for its Employee Retirement Plan. The Form 5500 along
with an audit report was due October 15, 1998. The Company may be assessed
penalties by both the Department of Labor and the Internal Revenue Service for
its late filing. The Company has provided for such penalties.

ITEM 14.      INDEMNIFICATION OF DIRECTORS AND OFFICERS

      Section 145 of the Delaware General Corporation Law, as amended, provides
that a corporation may indemnify any person who was or is a party to or is
threatened to be made a party to any threatened, pending or completed action or
proceeding, whether civil, criminal, administrative or investigative, by reason
of the fact that he is or was a director, officer, employee or agent of the
corporation or is or was serving at its request in such capacity in another
corporation or business association, against expenses (including attorney's
fees), judgments, fines and amounts paid in settlement actually and reasonably
incurred by him in connection with such action, suit or proceeding if her acted
in good faith and in a manner he reasonably believed to be in or not opposed to
the best interests of the corporation, and with respect to any criminal action
or proceeding, had no reasonable cause to believe his conduct was unlawful.

      Section 107(b)(7) of the Delaware General Corporation Law, as amended,
permits a corporation to provide in its certificate of incorporation that a
director of the corporation shall not

                                     II-1
<PAGE>
 
be personally liable to the corporation or its shareholders for monetary damages
for breach of fiduciary duty as a director, except for liability (a) for any
breach of the director's duty of loyalty to the corporation or its shareholders,
(b) for acts or omissions not in good faith or which involve intentional
misconduct or a knowing violation of law, (c) under Section 174 of the Delaware
General Corporation Law, or (d) for any transaction from which the director
derived an improper personal benefit.

      Article V of the Registrant's Amended and Restated Certificate of
Incorporation provides for the elimination of personal liability for a director
for breach of fiduciary duty as permitted by 102(b)(7) of the Delaware General
Corporation Law. Article VI of the Registrant's Amended and Restated By-Laws
provide that the Registrant shall indemnify its directors, officers and
employees to the full extent permitted by Section 145 of the Delaware General
Corporation Law.

      The Underwriting Agreement (filed as Exhibit 1 hereto) provides for
indemnification by the Underwriters of the Registrant and its directors,
officers and controlling persons for certain liabilities arising under the
Securities Act or otherwise.

ITEM 15.      RECENT SALES OF UNREGISTERED SECURITIES

      In February 1999 Registrant issued 100 shares of its common stock to Kris
Shah, its promoter, in connection with the organization of the Registrant and
this offering for $100. On the date of this prospectus, Registrant issued
3,870,593 shares of common stock to the shares of Litronic Industries, Inc. in
exchange for all the outstanding capital stock of Litronic Industries, Inc.

      The issuance of the securities in the transactions described above were
deemed to be exempt from registration under the Securities Act in reliance on
(a) Section 4(2) of the Securities Act and Regulation D promulgated thereunder
as a transaction by an issuer not involving any public offering.

ITEM 17.      UNDERTAKINGS

      The undersigned Registrant hereby undertakes to provide to the
underwriters at the closing specified in the underwriting agreements
certificates in such denominations and registered in such names as required by
the underwriters to permit prompt delivery to each purchaser.

      Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the Registrant pursuant to the foregoing provisions, or otherwise, the
Registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the Act
and is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Registrant of expenses
incurred or paid by a director, officer or controlling person of the Registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

      The undersigned Registrant hereby undertakes that:

      (1)     For purposes of determining any liability under the Securities Act
              of 1933, the information omitted from the form of prospectus filed
              as part of this registration statement in reliance upon Rule 430A
              and contained in a form of prospectus filed by the Registrant
              pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities
              Act shall be deemed to be part of this registration statement as
              of the time it was declared effective.

      (2)     For the purpose of determining any liability under the Securities
              Act of 1933, each post-effective amendment that contains a form of
              prospectus shall be deemed to be a new registration statement
              relating to the securities offered therein, and the offering of
              such securities at that time shall be deemed to be the initial
              bona fide offering thereof..

AMOUNT OF GUARANTY. This is a guaranty of payment of the Note, including without
limitation the principal Note amount of Two Million Three Hundred Sixty Thousand
& 00/100 Dollars ($2,360,000.00).

GUARANTY. For good and valuable consideration, PULSAR DATA SYSTEMS, INC.
("Guarantor") absolutely and unconditionally guarantees and promises to pay to
WILMINGTON TRUST COMPANY ("Lender") or its order, in legal tender of the United
States of America, the Indebtedness (as that term is defined below) of DAVIS
HOLDING COMPANY ("Borrower") to Lender on the terms and conditions set forth in
this Guaranty.

this Guaranty:

BORROWER. The word "Borrower" means DAVIS HOLDING COMPANY.
GUARANTOR. The word "Guarantor" means PULSAR DATA SYSTEMS, INC.
GUARANTY. The word ''Guaranty" means this Guaranty made by Guarantor for the

principal, (b) all interest, (c) all late charges, (d) all loan fees and loan
charges, and (e) all collection costs and expenses relating to the Note or to

limitation all of Lender's reasonable attorneys' fees and Lender's legal
expenses, including court costs and fifteen percent (15%) of the principal plus

collected by or through an attorney-at-law, whether or not suit is instituted,
and reasonable attorneys' fees and legal expenses for bankruptcy      
<PAGE>
 
                                    PAGE 2

    
proceedings (including efforts to modify or vacate any automatic stay or
injunction), appeals, and any anticipated post-judgment collection services.

LENDER. The word "Lender" means WILMINGTON TRUST COMPANY, its successors and
assigns.

NOTE. The word "Note" means the promissory note or credit agreement dated JUNE
23, 1995, in the original principal amount of $2,360,000.00 from Borrower to
Lender, together with all renewals of, extensions of, modifications of,

agreement.

RELATED DOCUMENTS. The words "Related Documents" mean and include without
limitation all promissory notes, credit agreements, loan agreements,
environmental agreements, guaranties, security agreements, mortgages, deeds of
trust, and all other instruments, agreements and documents, whether now or
hereafter existing, executed in connection with the Indebtedness.

MAXIMUM LIABILITY. The maximum liability of Guarantor under this guaranty shall
not exceed at any one time the amount of the Indebtedness described above, plus
all costs and expenses of (a) enforcement of this Guaranty and (b) collection
and sale of any collateral securing this Guaranty.

The above limitation on liability is not a restriction on the amount of the
Indebtedness of Borrower to Lender either in the aggregate or at any one time.
If Lender presently holds one or more guaranties, or hereafter receives
additional guaranties from Guarantor, the rights of Lender under all guaranties
shall be cumulative. This Guaranty shall not (unless specifically provided below
to the contrary) affect or invalidate any such other guaranties. The liability
of Guarantor will be the aggregate liability of Guarantor under the terms of
this Guaranty and any such other unterminated guaranties.

NATURE OF GUARANTY. Guarantor intends to guarantee at all times the performance
and prompt payment when due, whether at maturity or earlier by reason of
acceleration or otherwise, of all Indebtedness within the limits set forth in
the preceding section of this Guaranty.

DURATION OF GUARANTY. This Guaranty will take effect when received by Lender
without the necessity of any acceptance by Lender, or any notice to Guarantor or
to Borrower, and will continue in full force until all Indebtedness shall have
been fully and finally paid and satisfied and all other obligations of Guarantor
under this Guaranty shall have been performed in full. Release of any other
guarantor or termination of any other guaranty of the Indebtedness shall not
affect the liability of Guarantor under this Guaranty. A revocation received by
Lender from any one or more Guarantors shall not affect the liability of any
remaining Guarantors under this Guaranty.

GUARANTOR'S AUTHORIZATION TO LENDER. GUARANTOR AUTHORIZES LENDER, without notice
or demand and without lessening Guarantor's liability under this Guaranty, from
time to time:  (a) to make one or more additional secured or unsecured loans to
Borrower, to lease equipment or other goods to Borrower, or otherwise to extend
additional credit to Borrower; (b) to alter, compromise, renew, extend,
accelerate, or otherwise change one or      
<PAGE>
 
                                    PAGE 3

    
more times the time for payment or other terms of the indebtedness or any part
of the Indebtedness, including increases and decreases of the rate of interest
on the Indebtedness; extensions may be repeated and may be for longer than the
original loan term; (c) to take and hold security for the payment of this
Guaranty or the indebtedness, and exchange, enforce, waive, fail or decide not
to perfect, and release any such security, with or without the substitution of
new collateral; (d) to release, substitute, agree not to sue, or deal with any
one or more of Borrower's sureties, endorsers, or other guarantors on any terms
or in any manner Lender may choose; (e) to determine how, when and what
application of payments and credits shall be made on the Indebtedness; (f) to
apply such security and direct the order or manner of sale thereof, including
without limitation, any nonjudicial sale permitted by the terms of the
controlling security agreement or deed of trust, as Lender in its discretion may
determine; (g) to sell, transfer, assign, or grant participations in all or any
part of the Indebtedness; and (h) to assign or transfer this Guaranty in whole
or in part.

GUARANTOR'S REPRESENTATIONS AND WARRANTIES. Guarantor represents and warrants to
Lender that (a) no representations or agreements of any kind have been made to
Guarantor which would limit or qualify in any way the terms of this Guaranty;
(b) this Guaranty is executed at Borrower's request and not at the request of
Lender; (c) Guarantor has not and will not, without the prior written consent of
Lender, sell, lease, assign, encumber, hypothecate, transfer, or otherwise
dispose of all or substantially all of Guarantor's assets, or any interest
therein; (d) Lender has made no representation to Guarantor as to the
creditworthiness of Borrower; (e) upon Lender's request, Guarantor will provide
to Lender financial and credit information in form acceptable to Lender, and all
such financial information provided to Lender is true and correct in all
material respects and fairly presents the financial condition of Guarantor as of
the dates thereof, and no material adverse change has occurred in the financial
condition of Guarantor since the date of the financial statements; and (f)
Guarantor has established adequate means of obtaining from Borrower on a
continuing basis information regarding Borrower's financial condition. Guarantor
agrees to keep adequately informed from such means of any facts, events, or
circumstances which might in any way affect Guarantor's risks under this
Guaranty, and Guarantor further agrees that, absent a request for information,
Lender shall have no obligation to disclose to Guarantor any information or
documents acquired by Lender in the course of its relationship with Borrower.

GUARANTOR'S WAIVERS. Except as prohibited by applicable law, Guarantor waives
any right to require Lender (a) to continue extending money or to extend other
credit to Borrower; (b) to make any presentment, protest, demand, or notice of
any kind, including notice of any nonpayment of the Indebtedness or of any
nonpayment related to any collateral, or notice of any action or nonaction on
the part of Borrower, Lender, any surety, endorser, or other guarantor in
connection with the Indebtedness or in connection with the creation of new or
additional loans or obligations; (c) to resort for payment or to proceed
directly or at once against any person, including Borrower or any other
guarantor; (d) to proceed directly against or exhaust any      
<PAGE>
 
                                    PAGE 4

    
collateral held by Lender from Borrower, any other guarantor, or any other
person; (e) to give notice of the terms, time, and place of any public or
private sale of personal property security held by Lender from Borrower or to
comply with any other applicable provisions of the Uniform Commercial Code; (f)
to pursue any other remedy within Lender's power; or (g) to commit any act or
omission of any kind, or at any time, with respect to any matter whatsoever.

If now or hereafter (a) Borrower shall be or become insolvent, and (b) the
Indebtedness shall not at all times until paid be fully secured by collateral
pledged by Borrower, Guarantor hereby forever waives and relinquishes in favor
of Lender and Borrower, and their respective successors, any claim or right to
payment Guarantor may now have or hereafter have or acquire against Borrower, by
subrogation or otherwise, so that at no time shall Guarantor be or become a
"creditor" of Borrower within the meaning of 11 U.S.C. section 547(b), or any
successor provision of the Federal bankruptcy laws.

Guarantor also waives any and all rights or defenses arising by reason of (a)
any "one action" or "anti-deficiency" law or any other law which may prevent
Lender from bringing any action, including a claim for deficiency, against
Guarantor, before or after Lender's commencement or completion of any
foreclosure action, either judicially or by exercise of a power of sale; (b) any
election of remedies by Lender which destroys or otherwise adversely affects
Guarantor's subrogation rights or Guarantor's rights to proceed against Borrower
for reimbursement, including without limitation, any loss of rights Guarantor
may suffer by reason of any law limiting, qualifying, or discharging the
Indebtedness; (c) any disability or other defense of Borrower, of any other
guarantor, or of any other person, or by reason of the cessation of Borrower's
liability from any cause whatsoever, other than payment in full in legal tender,
of the Indebtedness; (d) any right to claim discharge of the Indebtedness on the
basis of unjustified impairment of any collateral for the Indebtedness; (e) any
statute of limitations, if at any time any action or suit brought by Lender
against Guarantor is commenced there is outstanding Indebtedness of Borrower to
Lender which is not barred by any applicable statute of limitations; or (f) any
defenses given to guarantors at law or in equity other than actual payment and
performance of the Indebtedness. If payment is made by Borrower whether
voluntarily or otherwise, or by any third party, on the Indebtedness and
thereafter Lender is forced to remit the amount of that payment to Borrower's
trustee in bankruptcy or to any similar person under any federal or state
bankruptcy law or law for the relief of debtors, the Indebtedness shall be
considered unpaid for the purpose of enforcement of this Guaranty. Guarantor
further waives and agrees not to assert or claim at any time any deductions to
the amount guaranteed under this Guaranty for any claim of setoff, counterclaim,
counter demand, recoupment or similar right, whether such claim, demand or right
may be asserted by the Borrower, the Guarantor, or both.

GUARANTOR'S UNDERSTANDING WITH RESPECT TO WAIVERS. Guarantor warrants and agrees
that each of the waivers set forth above is made with Guarantor's full knowledge
of its significance and consequences and that, under the circumstances, the
waivers are reasonable and not contrary to public policy or law. If any such
waiver is determined to be      
<PAGE>
 
                                    PAGE 5

    
contrary to any applicable law or public policy, such waiver shall be effective
only to the extent permitted by law or public policy.

SUBORDINATION OF BORROWER'S DEBTS TO GUARANTOR. Guarantor agrees that the
Indebtedness of Borrower to Lender, whether now existing or hereafter created,
shall be prior to any claim that Guarantor may now have or hereafter acquire
against Borrower, whether or not Borrower becomes insolvent. Guarantor hereby
expressly subordinates any claim Guarantor may have against Borrower, upon any
account whatsoever, to any claim that Lender may now or hereafter have against
Borrower. In the event of insolvency and consequent liquidation of the assets of
Borrower, through bankruptcy, by an assignment for the benefit of creditors, by
voluntary liquidation, or otherwise, the assets of Borrower applicable to the
payment of the claims of both Lender and Guarantor shall be paid to Lender and
shall be first applied by Lender to the Indebtedness of Borrower to Lender.
Guarantor does hereby assign to Lender all claims which it may have or acquire
against Borrower or against any assignee or trustee in bankruptcy of Borrower;
provided however, that such assignment shall be effective only for the purpose
of assuring to Lender full payment in legal tender of the Indebtedness. If
Lender so requests, any notes or credit agreements now or hereafter evidencing
any debts or obligations of Borrower to Guarantor shall be marked with legend
that the same are subject to this Guaranty and shall be delivered to Lender.
Guarantor agrees, and Lender hereby is authorized, in the name of Guarantor,
from time to time to execute and file financing statements and continuation
statements and to execute such other documents and to take such other actions as
Lender deems necessary or appropriate to perfect, preserve and enforce its
rights under this Guaranty.

MISCELLANEOUS PROVISIONS. The following miscellaneous provisions are a part of
this Guaranty:

AMENDMENTS. This Guaranty, together with any Related Documents, constitutes the
entire understanding and agreement of the parties as to the matters set forth in
this Guaranty. No alteration of or amendment to this Guaranty shall be effective
unless given in writing and signed by the party or parties sought to be charged
or bound by the alteration or amendment.

APPLICABLE LAW. This Guaranty has been delivered to Lender and accepted by
Lender in the State of Delaware. This Guaranty shall be governed by and
construed in accordance with the laws of the State of Delaware.

ATTORNEYS' FEES; EXPENSES. Guarantor agrees to pay upon demand all of Lender's
costs and expenses, including reasonable attorneys' fees and Lender's legal
expenses, incurred in connection with the enforcement of this Guaranty. Lender
may pay someone else to help enforce this Guaranty, and Guarantor shall pay the
costs and expenses of such enforcement. Costs and expenses include Lender's
reasonable attorneys' fees and legal expenses whether or not there is a lawsuit,
including reasonable attorneys' fees and legal expenses for bankruptcy
proceedings (and including efforts to modify or vacate any automatic stay or
injunction), appeals, and any anticipated post-judgment collection services.
Guarantor also shall pay all court costs and such additional fees as may be
directed by the court.     
<PAGE>
 
                                    PAGE 6

    
NOTICES. All notices required to be given by either party to the other under
this Guaranty shall be in writing and shall be effective when actually delivered
or when deposited with a nationally recognized overnight courier, or when
deposited in the United States mail, first class postage prepaid, addressed to
the party to whom the notice is to be given at the address shown above or to
such other addresses as either party may designate to the other in writing. If
there is more than one Guarantor, notice to any Guarantor will constitute notice
to all Guarantors. For notice purposes, Guarantor agrees to keep Lender informed
at all times of Guarantor's current address.

INTERPRETATION. In all cases where there is more than one Borrower or Guarantor,
then all words used in this Guaranty in the singular shall be deemed to have
been used in the plural where the context and construction so require; and where
there is more than one Borrower named in this Guaranty or when this Guaranty is
executed by more than one Guarantor, the words "Borrower" and "Guarantor"
respectively shall mean all and any one or more of them. The words "Guarantor,"
"Borrower," and "Lender" include the heirs, successors, assigns, and transferees
of each of them. Caption headings in this Guaranty are for convenience purposes
only and are not to be used to interpret or define the provisions of this
Guaranty. If a court of competent jurisdiction finds any provision of this
Guaranty to be invalid or unenforceable as to any person or circumstance, such
finding shall not render that provision invalid or unenforceable as to any other
persons or circumstances, and all provisions of this Guaranty in all other
respects shall remain valid and enforceable. If any one or more of Borrower or
Guarantor are corporations or partnerships, it is not necessary for Lender to
inquire into the powers of Borrower or Guarantor or of the officers, directors,
partners, or agents acting or purporting to act on their behalf, and any
Indebtedness made or a created in reliance upon the professed exercise of such
powers shall be guaranteed under this Guaranty.

WAIVER. Lender shall not be deemed to have waived any rights under this Guaranty
unless such waiver is given in writing and signed by Lender. No delay or
omission on the part of Lender in exercising any right shall operate as a waiver
of such right or any other right. A waiver by Lender of a provision of this
Guaranty shall not prejudice or constitute a waiver of Lender's right otherwise
to demand strict compliance with that provision or any other provision of this
Guaranty. No prior waiver by Lender, nor any course of dealing between Lender
and Guarantor, shall constitute a waiver of any of Lender's rights or of any of
Guarantor's obligations as to any future transactions. Whenever the consent of
Lender is required under this Guaranty, the granting of such consent by Lender
in any instance shall not constitute continuing consent to subsequent instances
where such consent is required and in all cases such consent may be granted or
withheld in the sole discretion of Lender.

LIMITATION ON GUARANTY. Notwithstanding any other provision of this Guaranty,
- -----------------------                                                      
the liability of Guarantor under this Guaranty shall not exceed the amount which
would render this Guaranty unenforceable, void or voidable under (s)548 of the
Bankruptcy Code or by application of any Fraudulent Transfer or Fraudulent
Conveyance statute. In the event that the Guarantor shall claim that the amount
of its liability hereunder is less      
<PAGE>
 
                                    PAGE 7

    
than the amount of the indebtedness, the burden of proof with respect to the
amount of such liability shall rest with Guarantor in light of the fact that the
information concerning and circumstances of the financial condition of such
Guarantor are more readily available to and under the control of such Guarantor.

Waiver of Right to Trial by Jury. IN RECOGNITION OF THE HIGHER COSTS AND DELAY
- ---------------------------------                                             
WHICH MAY RESULT FROM A JURY TRIAL, GUARANTOR AND LENDER WAIVE ANY RIGHT TO
TRIAL BY JURY OF ANY CLAIM, DEMAND, ACTION OR CAUSE OF ACTION (1) ARISING
HEREUNDER, OR (2) IN ANY WAY CONNECTED WITH OR RELATED OR INCIDENTAL TO THE
DEALINGS OF THE PARTIES HERETO WITH RESPECT HERETO OR ANY OTHER INSTRUMENT,
DOCUMENT OR AGREEMENT EXECUTED OR DELIVERED IN CONNECTION HEREWITH, IN EACH CASE
WHETHER NOW EXISTING OR HEREAFTER ARISING, AND WHETHER SOUNDING IN CONTRACT OR
TORT OR OTHERWISE; AND EACH PARTY HEREBY AGREES AND CONSENTS THAT ANY SUCH
CLAIM, DEMAND, ACTION OR CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT
A JURY, AND THAT ANY PARTY HERETO MAY FILE AN ORIGINAL COUNTERPART OR A COPY OF
THIS SECTION WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE PARTIES
HERETO TO THE WAIVER OF THEIR RIGHT TO TRIAL BY JURY.

Waiver and Subordination. Guarantor irrevocably waives, disclaims and
- -------------------------
relinquishes all claims against Borrower which Guarantor otherwise has or would
have by virtue of having executed this Guaranty, specifically including but not
limited to all rights of indemnity, contribution or exoneration. In the event of
the payment by Guarantor to Lender of any amount whatsoever and the resultant
subrogation of Guarantor to the rights of Lender by reason of such payment, the
amount of the remaining Indebtedness of Borrower to Lender after the payments by
Guarantor pursuant to this Guaranty shall have priority over any claim that
Guarantor may have against Borrower, whether or not Borrower is at such time or
thereafter becomes insolvent. Guarantor further expressly subordinates any claim
against Borrower upon any account whatsoever to any claim that Lender may have
against Borrower at any time and for any reason.

EACH UNDERSIGNED GUARANTOR ACKNOWLEDGES HAVING READ ALL THE PROVISIONS OF THIS
GUARANTY AND AGREES TO ITS TERMS. IN ADDITION, EACH GUARANTOR UNDERSTANDS THAT
THIS GUARANTY IS EFFECTIVE UPON GUARANTOR'S EXECUTION AND DELIVERY OF THIS
GUARANTY TO LENDER AND THAT THE GUARANTY WILL CONTINUE UNTIL TERMINATED IN THE
MANNER SET FORTH IN THE SECTION TITLED "DURATION OF      
<PAGE>
 
                                    PAGE 8

GUARANTY." NO FORMAL ACCEPTANCE BY LENDER IS NECESSARY TO MAKE THIS GUARANTY
EFFECTIVE. THIS GUARANTY IS DATED JUNE 23, 1995.

===============================================================================
    
     enter upon the properties to make such inspections and tests as Lender may
     deem appropriate to determine compliance of the properties with this
     section of the Agreement. Any inspections or tests made by Lender shall be
     at Borrower's expense and for Lender's purposes only and shall not be
     construed to create any responsibility or liability on the part of Lender
     to Borrower or to any other person. The representations and warranties
     contained herein are based on Borrower's due diligence in investigating the
     properties for hazardous waste and hazardous substances. Borrower hereby
     (a) releases and waives any future claims against Lender for indemnity or
     contribution in the event Borrower becomes liable for cleanup or other
     costs under any such laws, and (b) agrees to indemnify and hold harmless
     Lender against any and all claims, losses, liabilities, damages, penalties,
     and expenses which Lender may directly or indirectly sustain or suffer
     resulting from a breach of this section of the Agreement or as a
     consequence of any use, generation, manufacture, storage, disposal, release
     or threatened release occurring prior to Borrower's ownership or interest
     in the properties, whether or not the same was or should have been known to
     Borrower. The provisions of this section of the Agreement, including the
     obligation to indemnify, shall survive the payment of the indebtedness and
     the termination or expiration of this Agreement and shall not be affected
     by Lender's acquisition of any interest in any of the properties, whether
     by foreclosure or otherwise.     

     LITIGATION AND CLAIMS.  No litigation, claim, investigation, administrative
     proceeding or similar action (including those for unpaid taxes) against
     Borrower is pending or threatened, and no other event has occurred which
     may materially adversely affect Borrower's financial condition or
     properties, other than litigation, claims, or other events, if any, that
     have been disclosed to and acknowledged by Lender in writing.

     Borrower that are or were required to be filed, have been filed, and all
     taxes, assessments and other governmental charges have been paid in full,

     in the ordinary course of business and for which adequate reserves have
     been provided.

     LIEN PRIORITY.  Unless otherwise previously disclosed to Lender in writing,
     Borrower has not entered into or granted any Security Agreements, or
     permitted the filing or attachment of any Security Interests on or
     affecting any of the Collateral directly or indirectly securing repayment
     of Borrower's Loan and Note, that would be prior or that may in any way be
     superior to Lender's Security Interests and rights in and to such
     Collateral.

     BINDING EFFECT.  This Agreement, the Note, all Security Agreements directly
     or indirectly securing repayment of Borrower's Loan and Note and all of the
     Related Documents are binding upon Borrower as well as upon Borrower's

     and warranties set forth in this Agreement are true and correct as of the
     date of the certificate and further certifying that, as of the date of the

capital as a consequence of Lender's obligations with respect to the credit
facilities to which this Agreement relates, then Borrower agrees to pay Lender
such additional amounts as will compensate Lender therefor, within five (5) days
after Lender's written demand for such payment, which demand shall be

reasonable detail of the additional amounts payable by Borrower, which
explanation and calculations shall be conclusive in the absence of manifest

     (as defined in the Internal Revenue Code of 1986, as amended), Borrower may
     pay cash dividends on its stock to its shareholders from time to time in
     amounts necessary to enable the shareholders to pay income taxes and make
     estimated income tax payments to satisfy their liabilities under federal
     and state law which arise solely from their status as Shareholders of a

Borrower, whether under this Agreement or under any other agreement, Lender

(a) Borrower or any Guarantor is in default under the terms of this Agreement or
any of the Related Documents or any other agreement that Borrower or any
Guarantor has

===============================================================================
    

with Lender; (b) Borrower or any guarantor becomes insolvent, files a petition
in bankruptcy or similar proceedings, or is adjudicated a bankrupt; (c) there
occurs a material adverse change in Borrower's financial condition, in the
financial condition of any Guarantor, or in the value of any Collateral securing
any Loan; or (d) any Guarantor seeks, claims or otherwise attempts to limit,
modify or revoke such Guarantor's guaranty of the Loan or any other loan with
Lender.

under this Agreement:

     Default on Indebtedness.  Failure of Borrower to make any payment when due
     on the Loans.     
     
     OTHER DEFAULTS.  Failure of Borrower or any Grantor to comply with or to
     perform when due any other term, obligation, covenant or condition
     contained in this Agreement or in any of the Related Documents, or failure
     of Borrower to comply with or to perform any other term, obligation,
     covenant or condition contained in any other agreement between Lender and
     Borrower.
    
     DEFAULT IN FAVOR OF THIRD PARTIES. Should Borrower or any Grantor default
     under any loan, extension of credit, security agreement, purchase or sales
     agreement, or any other agreement, in favor of any other creditor or person
     that may materially affect any of Borrower's property or Borrower's or any
     Grantor's ability to repay the Loans or perform their respective
     obligations under this Agreement or any of the Related Documents.     

     FALSE STATEMENTS.  Any warranty, representation or statement made or
     furnished to Lender by or on behalf of Borrower or any Grantor under this
     Agreement or the Related Documents is false or misleading in any material
     respect at the time made or furnished, or becomes false or misleading at
     any time thereafter.

     DEFECTIVE COLLATERALIZATION.  This Agreement or any of the Related
     Documents ceases to be in full force and effect (including failure of any
     Security Agreement to create a valid and perfected Security Interest) at
     any time or for any reason.
    
     INSOLVENCY.  The dissolution or termination of Borrower's existence as a
     going business, the insolvency of Borrower, the appointment of a receiver
     for any part of Borrower's property, any assignment for the benefit of

     proceeding under any bankruptcy or insolvency laws by or against  
     Borrower.     

     CREDITOR OR FORFEITURE PROCEEDINGS.  Commencement of foreclosure or
     forfeiture proceedings, whether by judicial proceeding, self-help,
     repossession or any other method, by

===============================================================================
    
     any creditor of Borrower, any creditor of any Grantor against any
     collateral securing the indebtedness, or by any governmental agency. This
     includes a garnishment, attachment, or levy on or of any of Borrower's
     deposit accounts with Lender.

     EVENTS AFFECTING GUARANTOR.  Any of the preceding events occurs with
     respect to any Guarantor of any of the indebtedness or any Guarantor dies
     or becomes incompetent, or revokes or disputes the validity of, or
     liability under, any Guaranty of the indebtedness.

EFFECT OF AN EVENT OF DEFAULT.  If any Event of Default shall occur, except
where otherwise provided in this Agreement or the Related Documents, all
commitments and obligations of Lender under this Agreement or the Related
Documents or any other agreement immediately will terminate (including any
obligation to make Loan Advances or disbursements), and, at Lender's option, all
indebtedness immediately will become due and payable, all without notice of any
kind to Borrower, except that in the case of an Event of Default of the type
described in the "Insolvency" subsection above, such acceleration shall be
automatic and not optional.  In addition, Lender shall have all the rights and
remedies provided in the Related Documents or available at law, in equity, or
otherwise.  Except as may be prohibited by applicable law, all of Lender's
rights and remedies shall be cumulative and may be exercised singularly or
concurrently.  Election by Lender to pursue any remedy shall not exclude pursuit
of any other remedy, and an election to make expenditures or to take action to
perform an obligation of Borrower or of any Grantor shall not affect Lender's
right to declare a default and to exercise its rights and remedies.
    
MISCELLANEOUS PROVISIONS.  The following miscellaneous provisions are a part of
this Agreement:     
    

     AMENDMENTS.  This Agreement, together with any Related Documents,
     constitutes the entire understanding and agreement of the parties as to the
     matters set forth in this Agreement.  No alteration of or amendment to this
     Agreement shall be effective unless given in writing and signed by the
     party or parties sought to be charged or bound by the alteration or
     amendment.

     APPLICABLE LAW.  This Agreement has been delivered to Lender and accepted
     by Lender in the State of Delaware.  If there is a lawsuit, Borrower agrees
     upon Lender's request to submit to the jurisdiction of the courts of NEW
     CASTLE County, the State of Delaware.  Lender and Borrower hereby waive the
     right to any jury trial in any action, proceeding, or

===============================================================================

     counterclaim brought by either Lender or Borrower against the other. This
     Agreement shall be governed by and construed in accordance with the laws of
     the State of Delaware.

     CAPTION HEADINGS.  Caption headings in this Agreement are for convenience
     purposes only and are not to be used to interpret or define the provisions
     of this Agreement.

     MULTIPLE PARTIES; CORPORATE AUTHORITY.  All obligations of Borrower under
     this Agreement shall be joint and several, and all references to Borrower
     shall mean each and every Borrower.  This means that each of the Borrowers
     signing below is responsible for all obligations of this Agreement.
    
     CONSENT TO LOAN PARTICIPATION.  Borrower agrees and consents to Lender's
     sale or transfer, whether now or later, of one or more participation
     interests in the Loans to one or more purchasers, whether related or
     unrelated to Lender.  Lender may provide, without any limitation
     whatsoever, to any one or more purchasers, or potential purchasers, any
     information or knowledge Lender may have about Borrower or about any other
     matter relating to the Loan, and Borrower hereby waives any rights to
     privacy it may have with respect to such matters.  Borrower additionally
     waives any and all notices of sale of participation interests, as well as
     all notices of any repurchase of such participation interests.  Borrower
     also agrees that the purchasers of any such participation interests will be
     considered as the absolute owners of such interests in the Loans and will
     have all the rights granted under the participation agreement or agreements
     governing the sale of such participation interests.  Borrower further
     waives all rights of offset or counterclaim that it may have now or later
     against Lender or against any purchaser of such a participation interest
     and unconditionally agrees that either Lender or such purchaser may enforce
     Borrower's obligation under the Loans irrespective of the failure or
     insolvency of any holder of any interest in the Loans.  Borrower further
     agrees that the purchaser of any such participation interests may enforce
     its interests irrespective of any personal claims or defenses that Borrower
     may have against Lender.     

     COSTS AND EXPENSES.  Borrower agrees to pay upon demand all of Lender's
     expenses, including without limitation reasonable attorneys' fees, incurred
     in connection with the preparation, execution, enforcement, modification
     and collection of this Agreement or in connection with the Loans made
     pursuant to this Agreement.  Lender may pay someone else to help collect
     the Loans and to enforce this Agreement, and Borrower will pay that amount.
     This includes, subject to any limits under applicable law, Lender's
     reasonable attorneys' fees and Lender's legal expenses, whether or not
     there is a lawsuit, including reasonable attorneys' fees for bankruptcy
     proceedings (including efforts to modify or vacate any automatic stay or
     injunction), appeals, and any anticipated post-judgment collection
     services.  Borrower also will pay any court costs, in addition to all other
     sums provided by law.

===============================================================================
    
     NOTICES.  All notices required to be given under this Agreement shall be
     given in writing, may be sent by telefacsimile, and shall be effective
     when actually delivered or when deposited with a nationally recognized
     overnight courier or deposited in the United States mail, first class,
     postage prepaid, addressed to the party to whom the notice is to be given
     at the address shown above.  Any party may change its address for notices
     under this Agreement by giving formal written notice to the other parties,
     specifying that the purpose of the notice is to change the party's address.
     To the extent permitted by applicable law, if there is more than one
     Borrower, notice to any Borrower will constitute notice to all Borrowers.
     For notice purposes, Borrower agrees to keep Lender informed at all times
     of Borrower's current address(es).     

     SEVERABILITY.  If a court of competent jurisdiction finds any provision of
     this Agreement to be invalid or unenforceable as to any person or
     circumstance, such finding shall not render that provision invalid or
     unenforceable as to any other persons or circumstances.  If feasible, any
     such offending provision shall be deemed to be modified to be within the
     limits of enforceability or validity; however, if the offending provision
     cannot be so modified, it shall be stricken and all other provisions of
     this Agreement in all other respects shall remain valid and enforceable.

     SUBSIDIARIES AND AFFILIATES OF BORROWER.  To the extent the context of any
     provisions of this Agreement makes it appropriate, including without
     limitation any representation, warranty or covenant, the word "Borrower" as
     used herein shall include all subsidiaries and affiliates of Borrower.
     Notwithstanding the foregoing however, under no circumstances shall this
     Agreement be construed to require Lender to make any Loan or other
     financial accommodation to any subsidiary or affiliate of Borrower.

     SUCCESSORS AND ASSIGNS.  All covenants and agreements contained by or on
     behalf of Borrower shall bind its successors and assigns and shall inure to
     the benefit of Lender, its successors and assigns.  Borrower shall not,
     however, have the right to assign its rights under this Agreement or any
     interest therein, without the prior written consent of Lender.

     SURVIVAL.  All warranties, representations, and covenants made by Borrower
     in this Agreement or in any certificate or other instrument delivered by
     Borrower to Lender under this Agreement shall be considered to have been
     relied upon by Lender and will survive the making of the Loan and delivery
     to Lender of the Related Documents, regardless of any investigation made by
     Lender or on Lender's behalf.

     TIME IS OF THE ESSENCE.  Time is of the essence in the performance of this
     Agreement.

     WAIVER.  Lender shall not be deemed to have waived any rights under this
     Agreement unless such waiver is given in writing and signed by Lender.  No
     delay or omission on the part of Lender in exercising any right shall
     operate as a waiver of such right or any other right.  A

===============================================================================
    
     waiver by Lender of a provision of this Agreement shall not prejudice or
     constitute a waiver of Lender's right otherwise to demand strict compliance
     with that provision or any other provision of this Agreement. No prior
     waiver by Lender, nor any course of dealing between Lender and Borrower, or
     between Lender and any Grantor, shall constitute a waiver of any of
     Lender's rights or of any obligations of Borrower or of any Grantor as to
     any future transactions. Whenever the consent of Lender is required under
     this Agreement, the granting of such consent by Lender in any instance
     shall not constitute continuing consent in subsequent instances where such
     consent is required, and in all cases such consent may be granted or
     withheld in the sole discretion of Lender.

     PERFECTION OF SECURITY INTEREST.  Grantor agrees to execute such financing
     statements and to take whatever other actions are requested by Lender to
     perfect and continue Lender's security interest in the Collateral. Upon
     request of Lender, Grantor will deliver to Lender any and all of the
     documents evidencing or constituting the Collateral, and Grantor will note
     Lender's interest upon any and all chattel paper if not delivered to Lender
     for possession by Lender. Grantor hereby appoints Lender as its irrevocable
     attorney-in-fact for the purpose of executing any documents necessary to
     perfect or to continue the security interest granted in this Agreement.
     Lender may at any time, and without further authorization from Grantor,
     file a carbon, photographic or other reproduction of any financing
     statement or of this Agreement for use as a financing statement. Grantor
     will reimburse Lender for all expenses for the perfection and the
     continuation of the perfection of Lender's security interest in the
     Collateral. Grantor promptly will notify Lender before any change in
     Grantor's name including any change to the assumed business names of
     Grantor. This is a continuing Security Agreement and will continue in
     effect even though all or any part of the Indebtedness is paid in full and
     even though for a period of time Grantor may not be indebted to Lender.

     NO VIOLATION.  The execution and delivery of this Agreement will not
     violate any law or agreement governing Grantor or to which Grantor is a
     party, and its certificate or articles of incorporation and bylaws do not
     prohibit any term or condition of this Agreement.

    
     ENFORCEABILITY OF COLLATERAL.  To the extent the Collateral consists of
     accounts, chattel paper, or general intangibles, the Collateral is
     enforceable in accordance with its terms, is genuine, and complies with
     applicable laws concerning form, content and manner of preparation and
     execution, and all persons appearing to be obligated on the Collateral have
     authority and capacity to contract and are in fact obligated as they appear
     to be on the Collateral. At the time any account becomes subject to a
     security interest in favor of Lender, the account shall be a good and valid
     account representing an undisputed, bona fide indebtedness incurred by the
     account debtor, for merchandise held subject to delivery instructions or
     theretofore shipped or delivered pursuant to a contract of sale, or     
<PAGE>
 
07-24-1995               COMMERCIAL SECURITY AGREEMENT                    Page 4
                                  (Continued)

     for services theretofore performed by Grantor with or for the account
     debtor; there shall be no setoffs or counterclaims against any such
     account; and no agreement under which any deductions or discounts may be
     claimed shall have been made with the account debtor except those disclosed
     to Lender in writing.

     LOCATION OF THE COLLATERAL.  Grantor, upon request of Lender, will deliver
     to Lender in form satisfactory to Lender a schedule of real properties and
     Collateral locations relating to Grantor's operations, including without
     limitation the following: (a) all real property owned or being purchased by
     Grantor; (b) all real property being rented or leased by Grantor; (c) all
     storage facilities owned, rented, leased, or being used by Grantor; and (d)
     all other properties where Collateral is or may be located.  Except in the
     ordinary course of its business, Grantor shall not remove the Collateral
     from its existing locations without the prior written consent of Lender.

    
     REMOVAL OF COLLATERAL.  Grantor shall keep the Collateral (or to the extent
     the Collateral consists of intangible property such as accounts, the
     records concerning the Collateral) at Grantor's address shown above, or at
     such other locations as are acceptable to Lender. Except in the ordinary
     course of its business, including the sales of inventory, Grantor shall not
     remove the Collateral from its existing locations without the prior written
     consent of Lender. To the extent that the Collateral consists of vehicles,
     or other titled property, Grantor shall not take or permit any action which
     would require application for certificates of title for the vehicles
     outside the State of Maryland, without the prior written consent of
     Lender.    

     TRANSACTIONS INVOLVING COLLATERAL.  Except for inventory sold or accounts
     collected in the ordinary course of Grantor's business, Grantor shall not
     sell, offer to sell, or otherwise transfer or dispose of the Collateral.
     While Grantor is not in default under this Agreement, Grantor may sell
     inventory, but only in the ordinary course of its business and only to
     buyers who qualify as a buyer in the ordinary course of business.  A sale
     in the ordinary course of Grantor's business does not include a transfer in
     partial or total satisfaction of a debt or any bulk sale.  Grantor shall
     not pledge, mortgage, encumber or otherwise permit the Collateral to be
     subject to any lien, security interest, encumbrance, or charge, other than
     the security interest provided for in this Agreement, without the prior
     written consent of Lender.  This includes security interests even if junior
     in right to the security interests granted under this  Agreement.  Unless
     waived by Lender, all proceeds from any disposition of the Collateral (for
     whatever reason) shall be held in trust for Lender and shall not be
     commingled with any other funds; provided however, this requirement shall
     not constitute consent by Lender to any sale or other disposition.  Upon
     receipt, Grantor shall immediately deliver any such proceeds to Lender.

     TITLE.  Grantor represents and warrants to Lender that it holds good and
     marketable title to the Collateral, free and clear of all liens and
     encumbrances except for the lien of this Agreement.  No financing statement
     covering any of the Collateral is on file in any public

     office other than those which reflect the security interest created by this
     Agreement or to which Lender has specifically consented. Grantor shall
     defend Lender's rights in the Collateral against the claims and demands of
     all other persons.

     COLLATERAL SCHEDULES AND LOCATIONS.  As often as Lender shall require, and
     insofar as the Collateral consists of accounts and general intangibles,
     Grantor shall deliver to Lender schedules of such Collateral, including
     such information as Lender may require, including without limitation names
     and addresses of account debtors and agings of accounts and general
     intangibles.  Insofar as the Collateral consists of inventory and
     equipment, Grantor shall deliver to Lender, as often as Lender shall
     require, such lists, descriptions, and designations of such Collateral as
     Lender may require to identify the nature, extent, and location of such
     Collateral.  Such information shall be submitted for Grantor and each of
     its subsidiaries or related companies.

     MAINTENANCE AND INSPECTION OF COLLATERAL.  Grantor shall maintain all
     tangible Collateral in good condition and repair.  Grantor will not commit
     or permit damage to or destruction of the Collateral or any part of the
     Collateral.  Lender and its designated representatives and agents shall
     have the right at all reasonable times to examine, inspect, and audit the
     Collateral wherever located.

     TAXES, ASSESSMENTS AND LIENS.  Grantor will pay when due all taxes,
     assessments and liens upon the Collateral, its use or operation, upon this
     Agreement, upon any promissory note or notes evidencing the Indebtedness,
     or upon any of the other Related Documents.  Grantor may withhold any such
     payment or may elect to contest any lien if Grantor is in good faith
     conducting an appropriate proceeding to contest the obligation to pay and
     so long as Lender's interest in the Collateral is not jeopardized in
     Lender's sole opinion.  If the Collateral is subjected to a lien which is
     not discharged within fifteen (15) days, Grantor shall deposit with Lender
     cash, a sufficient corporate surety bond or other security satisfactory to
     Lender in an amount adequate to provide for the discharge of the lien plus
     any interest, costs, reasonable attorneys' fees or other charges that could
     accrue as a result of foreclosure or sale of the Collateral.  In any
     contest Grantor shall defend itself and Lender and shall satisfy any final
     adverse judgment before enforcement against the Collateral.  Grantor shall
     name Lender as an additional obligee under any surety bond furnished in the
     contest proceedings.

     COMPLIANCE WITH GOVERNMENTAL REQUIREMENTS.  Grantor shall comply promptly
     with all laws, ordinances, rules and regulations of all governmental
     authorities, now or hereafter in effect, applicable to the ownership,
     production, disposition, or use of the Collateral.  Grantor may contest in
     good faith any such law, ordinance or regulation and withhold compliance
     during any proceeding, including appropriate appeals, so long as Lender's
     interest in the Collateral, in Lender's opinion, is not jeopardized.

                                  (Continued)

     HAZARDOUS SUBSTANCES.  Grantor represents and warrants that the Collateral
     never has been, and never will be so long as this Agreement remains a lien
     on the Collateral, used for the generation, manufacture, storage,
     transportation, treatment, disposal, release or threatened release of any
     hazardous waste or substance, as those terms are defined in the
     Comprehensive Environmental Response, Compensation, and Liability Act of
     1980, as amended, 42 U.S.C. Section 9601, et seq. ("CERCLA"), the Superfund
     Amendments and Reauthorization Act of 1986, Publ L. No. 99-499 ("SARA"),
     the Hazardous Materials Transportation Act, 49 U.S.C. Section 1801, et
     seq., the Resource Conservation and Recovery Act, 49 U.S.C. Section 6901,
     et seq., or other applicable state or Federal laws, rules, or regulations
     adopted pursuant to any of the foregoing.  The terms "hazardous waste" and
     "hazardous substance" shall also include, without limitation, petroleum and
     petroleum by-products or any fraction thereof and asbestos.  The
     representations and warranties contained herein are based on Grantor's due
     diligence in investigating the Collateral for hazardous wastes and
     substances.  Grantor hereby (a) releases and waives any future claims
     against Lender for indemnity or contribution in the event Grantor becomes
     liable for cleanup or other costs under any such laws, and (b) agrees to
     indemnify and hold harmless Lender against any and all claims and losses
     resulting from a breach of this provision of this Agreement.  This
     obligation to indemnify shall survive the payment of the Indebtedness and
     the satisfaction of this Agreement.

    
     MAINTENANCE OF CASUALTY INSURANCE.  Grantor shall procure and maintain all
     risks insurance, including without limitation fire, theft and liability
     coverage together with such other insurance as Lender may require with
     respect to the Collateral, in form, amounts, coverages and basis acceptable
     to Lender and issued by a company or companies acceptable to Lender.
     Grantor, upon request of Lender, will deliver to Lender from time to time
     the policies or certificates of insurance in form satisfactory to Lender,
     including stipulations that coverages will not be cancelled or diminished
     without at least twenty (20) days' prior written notice to Lender and not
     including any disclaimer of the insurer's liability for failure to give
     such a notice.  Each insurance policy also shall include an endorsement
     providing that coverage in favor of Lender will not be impaired in any way
     by any act, omission or default of Grantor or any other person.  In
     connection with all policies covering assets in which Lender holds or is
     offered a security interest, Grantor will provide Lender with such loss
     payable or other endorsements as Lender may require.  If Grantor at any
     time fails to obtain or maintain any insurance as required under this
     Agreement, Lender may (but shall not be obligated to) obtain such insurance
     as Lender deems appropriate, including if it so chooses "single interest
     insurance," which will cover only Lender's interest in the Collateral.     

     APPLICATION OF INSURANCE PROCEEDS.  Grantor shall promptly notify Lender of
     any loss or damage to the Collateral.  Lender may make proof of loss if
     Grantor fails to do so within fifteen (15) days of the casualty.  All
     proceeds of any insurance on the Collateral, including accrued proceeds
     thereon, shall be held by Lender as part of the Collateral.  If Lender
<PAGE>
 
07-24-1995               COMMERCIAL SECURITY AGREEMENT                    Page 7
                                  (Continued)

     consents to repair or replacement of the damaged or destroyed Collateral,
     Lender shall, upon satisfactory proof of expenditure, pay or reimburse
     Grantor from the proceeds for the reasonable cost of repair or restoration.
     If Lender does not consent to repair or replacement of the Collateral,
     Lender shall retain a sufficient amount of the proceeds to pay all of the
     Indebtedness, and shall pay the balance to Grantor.  Any proceeds which
     have not been disbursed within six (6) months after their receipt and which
     Grantor has not committed to the repair or restoration of the Collateral
     shall be used to prepay the Indebtedness.

     INSURANCE REPORTS.  Grantor, upon request of Lender, shall furnish to
     Lender reports on each existing policy of insurance showing such
     information as Lender may reasonably request including the following: (a)
     the name of the insurer; (b) the risks insured; (c) the amount of the
     policy; (d) the property insured; (e) the then current value on the basis
     of which insurance has been obtained and the manner of determining that
     value; and (f) the expiration date of the policy.  In addition, Grantor
     shall upon request by Lender (however not more often than annually) have an
     independent appraiser satisfactory to Lender determine, as applicable, the
     cash value or replacement cost of the Collateral.

GRANTOR'S RIGHT TO POSSESSION AND TO COLLECT ACCOUNTS.  Until default and except
as otherwise provided below with respect to accounts, Grantor may have
possession of the tangible personal property and beneficial use of all the
Collateral and may use it in any lawful manner not inconsistent with this
Agreement or the Related Documents, provided that Grantor's right to possession
and beneficial use shall not apply to any Collateral where possession of the
Collateral by Lender is required by law to perfect Lender's security interest in
such Collateral.  Until otherwise notified by Lender, Grantor may collect any of
the Collateral consisting of accounts.  At any time and even though no Event of
Default exists, Lender may exercise its rights to collect the accounts and to
notify account debtors to make payments directly to Lender for application to
the Indebtedness.  If Lender at any time has possession of any Collateral,
whether before or after an Event of Default, Lender shall be deemed to have
exercised reasonable care in the custody and preservation of the Collateral if
Lender takes such action for that purpose as Grantor shall request or as Lender,
in Lender's sole discretion, shall deem appropriate under the circumstances, but
failure to honor any request by Grantor shall not of itself be deemed to be a
failure to exercise reasonable care.  Lender shall not be required to take any
steps necessary to preserve any rights in the Collateral against prior parties,
nor to protect, preserve or maintain any security interest given to secure the
Indebtedness.

EXPENDITURES BY LENDER.  If not discharged or paid when due, Lender may (but
shall not be obligated to) discharge or pay any amounts required to be
discharged or paid by Grantor under this Agreement, including without limitation
all taxes, liens, security interests, encumbrances, and other claims, at any
time levied or placed on the Collateral.  Lender also may (but shall not be
obligated to) pay all costs for insuring, maintaining and preserving the
Collateral.  All such expenditures incurred or paid by Lender for such purposes
will then bear interest at the rate charged under the Note from the date
incurred or paid by Lender to the date of repayment by Grantor.  All such

expenses shall become a part of the Indebtedness and, at Lender's option, will
(a) be payable on demand, (b) be added to the balance of the Note and b e
apportioned among and be payable with any installment payments to become due
during either (i) the term of any applicable insurance policy or (ii) the
remaining term of the Note, or (c) be treated as a balloon payment which will be
due and payable at the Note's maturity.  This Agreement also will secure payment
of these amounts.  Such rights shall be in addition to all other rights and
remedies to which Lender may be entitled upon the occurrence of an Event of
Default.

     property of Grantor to take possession of and remove the Collateral. If

therein; (d) Lender has made no representation to Guarantor as to the
creditworthiness of Borrower; (e) upon Lender's request, Guarantor will provide

<PAGE>
 
                                                                               3
    
with the creation of new or additional loans or obligations; (c) to resort for
payment or to proceed directly or at once against any person, including Borrower
or any other guarantor; (d) to proceed directly against or exhaust any
collateral held by Lender from Borrower, any other guarantor, or any other
person; (e) to give notice of the terms, time, and place of any public or
private sale of personal property security held by Lender from Borrower or to
comply with any other applicable provisions of the Uniform Commercial Code; (f)
to pursue any other remedy within Lender's power; or (g) to commit any act or
omission of any kind, or at any time, with respect to any matter 
whatsoever.     

If now or hereafter (a) Borrower shall be or become insolvent, and (b) the
Indebtedness shall not at all times until paid be fully secured by collateral
pledged by Borrower, Guarantor hereby forever waives and relinquishes in favor
of Lender and Borrower, and their respective successors, any claim or right to
payment Guarantor may now have or hereafter have or acquires against Borrower,
by subrogation or otherwise, so that at no time shall Guarantor be or become a
"creditor" of Borrower within the meaning of 11 U.S.C. section 547(b), or any
successor provision of the Federal bankruptcy laws.
    
Guarantor also waives any and all rights or defenses arising by reason of (a)
any "one action" or "anti-deficiency" law or any other law which may prevent
Lender from bringing any action, including a claim for deficiency, against
Guarantor, before or after Lender's commencement or completion of any
foreclosure action, either judicially or by exercise of a power of sale; (b) any
election of remedies by Lender with destroys or otherwise adversely affects
Guarantor's subrogation rights or Guarantor's rights to proceed against Borrower
for reimbursement, including without limitation, any loss of rights Guarantor
may suffer by reason of any law limiting, qualifying, or discharging the
Indebtedness; (c) any disability or other defense of Borrower, of any other
guarantor, or of any other person, or by reason of the cessation of Borrower's
liability from any cause whatsoever, other than payment in full in legal tender,
of the Indebtedness; (d) any right to claim discharge of the Indebtedness on the
basis of unjustified impairment of any collateral for the Indebtedness; (e) any
statute of limitations, if at any time any action or suit brought by Lender
against Guarantor is commenced there is outstanding Indebtedness of Borrower to
Lender which is not barred by any applicable statute of limitations; or (f) any
defenses given to guarantors at law or in equity other than actual payment and
performance of the Indebtedness. It payment is made by Borrower, whether
voluntarily or otherwise, or by any third party, on the Indebtedness and
thereafter Lender is forced to remit the amount of that payment to borrower's
trustee in bankruptcy or to any similar person under any federal or state
bankruptcy law or law for the relief of debtors, the Indebtedness shall be
considered unpaid for the purpose of enforcement of this Guaranty.     

Guarantor further waives and agrees not to assert or claim at any time any
deductions to the amount guaranteed under this Guaranty for any claim of setoff,
counterclaim, counter demand, recoupment or similar right, whether such claim,
demand or right may be asserted by the Borrower, the Guarantor, or both.
    
GUARANTOR'S UNDERSTANDING WITH RESPECT TO WAIVERS. Guarantor warrants and agrees
that each of the waivers set forth above is made with Guarantor s full knowledge
of its significance and consequences and that, under the circumstances, the
waivers are reasonable and not contrary to public policy or law. If any such
waiver is determined to be contrary to any applicable law or public policy, such
waiver shall be effective only to the extent permitted by law or public 
policy.     

SUBORDINATION OF BORROWERS DEBTS TO GUARANTOR. Guarantor agrees that the
Indebtedness of Borrower to Lender, whether now existing or hereafter created,
shall be prior to any claim that Guarantor may now have or hereafter acquire
against Borrower, whether or not Borrower becomes insolvent. Guarantor hereby
expressly subordinates any claim Guarantor may have against Borrower, upon any
account whatsoever, to any claim that Lender may now or hereafter have against
Borrower.   In the event of insolvency and consequent liquidation of the assets
of Borrower, through bankruptcy, by an assignment for the benefit of creditors,
by voluntary liquidation, or otherwise, the assets of Borrower applicable to the
payment of the claims of both Lender and Guarantor shall be paid to Lender and
shall be first applied by Lender to the Indebtedness of Borrower to Lender.
Guarantor does hereby assign to Lender all claims which it may have or acquire
against Borrower or against any assignee or trustee in bankruptcy of Borrower;
provided however, that such assignment shall be effective only for the purpose
of assuring to Lender full payment in legal tender of the Indebtedness.  If
Lender so requests, any notes or credit agreements now or hereafter evidencing
any debts or obligations of Borrower to Guarantor shall be marked with a legend
that the same are subject to this Guaranty and shall be delivered to Lender.
Guarantor agrees, and Lender hereby is authorized, in the name of Guarantor,
from time to time to execute and file financing statements and continuation
statements and to execute such other documents and to take such other actions as
Lender deems necessary or appropriate to perfect, preserve and enforce its
rights under this Guaranty.

CONFESSION OF JUDGMENT. Guarantor hereby irrevocably authorizes and empowers any
attorney-at-law to appear in any court of record and to confess judgment
against Guarantor for the unpaid amount of this Guaranty as evidenced by an
affidavit signed by an officer of Lender setting forth the amount then due, plus
attorneys' fees as provided in this Guaranty, plus costs of suit, and to
release all errors, and waive all rights of appeal.  If a copy of this
Guaranty, verified by an affidavit, shall have been filed in the proceeding, it
will not be necessary to file the original as a warrant of attorney.  Guarantor
waives the right to any say of execution and the benefit of all exemption laws
now or hereafter in effect. No single exercise of the foregoing  warrant and
power to confess judgment will be deemed to exhaust the power whether or not any
such exercise shall be held by any court to be invalid voidable or void; but the
power will continue undiminished and may be exercised from time to time as
Lender may elect until all amounts owing on this Guaranty have been paid in
full.     

MISCELLANEOUS PROVISIONS. The following miscellaneous provisions are a part of

     so require; and where there is more than one Borrower named in this
     Guaranty or when this Guaranty is executed by more than one Guarantor, the
     words "Borrower" and "Guarantor" respectively shall mean all and any one or
     more of them. The words "Guarantor," "Borrower," and "Lender" include the
     heirs, successors, assigns, and transferees of each of them. Caption
     headings in this Guaranty are for convenience purposes only and are not to
     be used to interpret or define the provisions of this Guaranty. If a court
     of competent jurisdiction finds any provision of this Guaranty to be
     invalid or unenforceable as to any person or circumstance, such finding
     shall not render that provision invalid or unenforceable as to any other
     persons or circumstances, and all provisions of this Guaranty in all other
     respects shall remain valid and enforceable. If any one or more of Borrower
     or Guarantor are corporations or partnerships, it is not necessary for
     Lender to inquire into the powers of Borrower or Guarantor or of the
     officers, directors, partners, or agents acting or purporting to act on
     their behalf, and any Indebtedness made or created in reliance upon the
     professed exercise of such powers shall be guaranteed under this 
     Guaranty.

                                                                               5

     WAIVER. Lender shall not be deemed to have waived any rights under this
     Guaranty unless such waiver is given in writing and signed by Lender.  No
     delay or omission on the part of Lender in exercising any right shall
     operate as a waiver of such right or any other right.   A waiver by Lender
     of a provision of this Guaranty shall not prejudice or constitute a waiver
     of Lender's right otherwise to demand strict compliance with that provision
     or any other provision of this Guaranty.  No prior waiver by Lender, nor
     any course of dealing between Lender and Guarantor, shall constitute a
     waiver of any of Lender's rights or of any of Guarantor's obligations as to
     any future transactions.  Whenever the consent of Lender is required under
     this Guaranty, the granting of such consent by Lender in any instance shall
     not constitute continuing consent to subsequent instances where such
     consent is required and in all cases such consent may be granted or
     withheld in the sole discretion of Lender.
    
LIMITATION ON GUARANTY.  Notwithstanding any other provision of this Guaranty,
the liability of Guarantor under this Guaranty shall not exceed the amount which
would render this Guaranty unenforceable, void or voidable under 548 of the
Bankruptcy Code or by application of any Fraudulent Transfer or Fraudulent
Conveyance statue.  In the event that Guarantor shall claim that the amount of
its liability hereunder is less than the amount of the Indebtedness, the burden
of proof with respect to the amount of such liability shall rest with
guarantor in light of the fact that the information concerning and circumstances
of the financial condition of such Guarantor are more readily available to and
under the control of such Guarantor.

WAIVER OF RIGHT TO TRIAL BY JURY.  In recognition of the higher costs and delay
which may result from a jury trial, guarantor and lender waive any right to
trial by jury of any claim, demand, action or cause of action (1) arising
hereunder, or (2) in any way connected with or related or incidental to the
dealings of the parties hereto with respect hereto or any other instrument,
document or agreement executed or delivered in connection herewith, in each case
whether now existing or hereafter arising, and whether sounding in contract or
tort or otherwise; and each party hereby agrees and consents  that any such
claim, demand, action or cause of action shall be decided by court trial
without a jury, and that any party hereto may file an original counterpart or a
copy of this section with any court as written evidence of the consent of the
parties hereto to the waiver of their right to trial by jury.

WAIVER AND SUBORDINATION.  Guarantor irrevocably waives, disclaims and
relinquishes all claims against Borrower which Guarantor otherwise has or would
have by virtue of having executed this Guaranty, specifically including but not
limited to all rights of indemnity, contribution or exoneration.  In the event
of the payment by Guarantor to Lender of any amount whatsoever and the resultant
subrogation of Guarantor to the rights of Lender by reason of such payment, the
amount of the remaining Indebtedness of Borrower to Lender after the payments by
Guarantor pursuant to this Guaranty shall have priority over any claim that
Guarantor may have against Borrower, whether or not Borrower is at such time or
thereafter becomes insolvent.  Guarantor further expressly subordinates any
claim against Borrower upon any account whatsoever to any claim that Lender may
have against Borrower at any time and for any reason.

EACH UNDERSIGNED GUARANTOR ACKNOWLEDGES HAVING READ ALL THE PROVISIONS OF THIS
GUARANTY AND AGREES TO ITS TERMS. IN ADDITION, EACH GUARANTOR UNDERSTANDS THAT
THIS GUARANTY IS EFFECTIVE UPON GUARANTOR'S EXECUTION AND DELIVERY OF THIS
GUARANTY TO LENDER AND THAT THE GUARANTY WILL CONTINUE UNTIL TERMINATED IN THE

with interest thereon, in the manner provided herein. The principal owing
hereunder in respect of the Revolver Advances at any given time shall equal the
aggregate amount of Revolver Advances made hereunder minus all principal
payments on the Revolver Advances received by Fidelity hereunder. Subject to the
terms and conditions hereof, the Company may borrow, repay and reborrow Revolver
Advances under this Agreement.

         2.2 Each request by the Company to Fidelity for a Revolver Advance

possession thereof.

         2.3. Promptly after receiving each Borrowing Base Certificate, Fidelity
shall, based upon such Borrowing Base Certificate and such other information
available to Fidelity, redetermine the Borrowing Base, which redetermination
shall take effect immediately and remain in effect until the next such
redetermination. If all conditions precedent to any Revolver Advance requested
have been met, Fidelity will on the date requested make such Revolver Advance
available to the Company by wire transfer to the account designated in writing
by the

                                       8
<PAGE>
 
Company. In the event Fidelity does not receive an appropriately completed
Borrowing Base Certificate, Fidelity shall have no obligation to redetermine the
Borrowing Base or make any additional Revolver Advances hereunder.

         2.4. If the aggregate unpaid principal balance of the Revolver Advances
exceeds the Borrowing Base at any time, the Company shall, upon receipt of
notice thereof from Fidelity, immediately repay the principal of the Revolver
Advances in an amount at least equal to such excess. Any principal repaid
pursuant to this Section 2.4. shall be in addition to, and not in lieu of, all
payments otherwise required to be paid under the Transaction Documents.

Company hereunder, that:

         7.1. The Company is a corporation duly organized, validly existing and
in good standing under the laws of the state of its incorporation, with all
requisite power and authority to execute, deliver and perform its obligations
under this Agreement and the other Transaction Documents to which it is a party
and to conduct its business as presently conducted. The Company is duly
qualified and authorized to do business as a foreign corporation and is in good
standing in all states in which such qualification and good standing are
necessary for the conduct by the Company of its business or the performance by
the Company of its obligations hereunder. The execution, delivery and
performance by the Company of this Agreement and the other Transaction Documents
to which it is a party do not and will not constitute (a) a violation of any
applicable law or the Company's articles or certificate of incorporation or
bylaws or (b) a material breach of any other document, agreement or instrument
to which the Company is a party or by which the Company is bound. This Agreement
and the other Transactions Documents to which the Company is a party have been
duly authorized, executed and delivered by the Company, and are legal, valid and
binding obligations of the Company enforceable against the Company in accordance
with their terms. No consent of, approval by, registration or filing with or
authorization from any governmental authority or agency is required in
connection with the execution, delivery or performance by the Company of this
Agreement or the other Transaction Documents to which it is a party.     

         7.2. None of the Eligible Accounts, the Eligible Inventory, the
Eligible Machinery and Equipment, the Real Property or any other Collateral is
subject to any lien, encumbrance, security interest or other claim of any kind
or nature, except for those liens that will be released upon the funding of the
first advance hereunder. The Company has not transferred, sold, pledged or given
a security interest in any of its Accounts, Inventory, machinery or equipment to
anyone other than Fidelity. There are no financing statements on file in any
public office governing any property of the Company of any kind, real or

         7.3. The Company is the sole owner and holder of, and has good and
defensible title to, all Collateral.

         7.4. The amount of each Eligible Account is due and owing to the
Company and represents an accurate statement of a bona fide sale, delivery and
acceptance of Inventory or performance of service by the Company to or for an
Account Debtor. The terms for payment of the Eligible Accounts are 30 days from
date of invoice and the payment of the Eligible Accounts is not contingent upon
the fulfillment by the Company of any further performance of any nature
whatsoever. There are no set-offs, allowances, discounts, deductions,
counterclaims against the Eligible Accounts or any claims by Account Debtors, of
any kind whatsoever, valid or invalid, that have been or may be asserted as a
basis for refusing to pay an Eligible Account, in whole or in part, either at
the time it is accepted by Fidelity for inclusion in the Borrowing Base or prior
to the date it is to be paid. To the best of the Company's knowledge, each
Account Debtor's business is solvent. The Company has served or caused to be
served any and all preliminary notices required by law to perfect or enforce any
mechanic's lien or stop notice or bonded stop notice for the Eligible Accounts
and the information contained in those notices is true and correct to the best
of the Company's knowledge.

to a merger or consolidation and has not acquired all or substantially all of
the assets of any Person.

Company has conducted its business in material compliance with all applicable
laws, including but not limited to, applicable Environmental Laws, and maintains
and is in compliance with all licenses and permits required under any such laws
to conduct its business and perform its obligations hereunder. The Company does
not have any known material contingent liability under any Environmental 
Law.     

         7.8. The application made by the Company to Fidelity in connection with
this Agreement and the statements made therein and in any materials furnished in
connection therewith are true and correct as of the date hereof. All financial

Accounts, contract rights and general intangibles, receivables and claims
whether now or hereafter arising, all guaranties and security therefor and all
of the Company's right title and interest in the goods purchased and represented
thereby including all of the Company's rights in and to returned goods and
rights of stoppage in transit, replevin and reclamation as unpaid vendor; (b)
all Inventory and all accessions thereto and products thereof and documents
therefor; (c) all equipment and machinery, wherever located and whether now or
hereafter existing, and all parts thereof, accessions thereto, and replacements
therefor and all documents and general intangibles covering or relating thereto;
(d) except to the extent prohibited by law or contract, all books and records
pertaining to the foregoing, including but not limited to computer programs,
data, certificates, records, circulation lists, subscriber lists, advertiser
lists, supplier lists, customer lists, customer and supplier contracts, sales
orders, and purchasing records; and (e) all proceeds of the foregoing
(collectively, the "Personal Property Collateral"). The Company agrees to comply
with all appropriate laws in order and to take all actions necessary or
desirable in Fidelity's judgment to perfect Fidelity's security interest in and
to the Personal Property Collateral, to execute any financing statement or
additional documents as Fidelity may request and to deliver to Fidelity a list
of all locations of its Inventory, equipment and machinery and landlord and or
mortgagee lien waivers with respect to each site where Inventory, equipment or
machinery is located and which is either leased by the Company or has been
mortgaged by the Company, upon request by Fidelity.

         Section 10. Collection. Each invoice representing an Account shall
state on its face that amounts payable thereunder are payable only at the
Remittance Address. Fidelity shall have the right at any time, either before or
after the occurrence of an Event of Default and without notice to the Company,
to notify any or all Account Debtors on the Personal Property Collateral of the
assignment of the Personal Property Collateral to Fidelity and to direct such
Account Debtors to make payment of all amounts due or to become due to the
Company directly to Fidelity, and to the extent permitted by law, to enforce
collection of any Personal Property Collateral and to adjust, settle or
compromise the amount or payment thereof. So long as no Event of Default or
event that, with the passage of time, the giving of notice or both, would become
an Event of Default has occurred and is continuing, all collections of Personal
Property Collateral or any other evidences of payment received by Fidelity shall
be applied by Fidelity to the payment of the Obligations of the Company to
Fidelity whether or not then due and any remaining funds shall be delivered to
the Company. Upon the occurrence of an Event of Default or an event that, with
the passage of time, the giving of notice or both, would become an Event of
Default, any such remaining funds may be held by Fidelity as cash collateral
("Cash Collateral") until all Obligations have been paid in full and Fidelity
has no further obligation to advance funds to the Company. All amounts and
proceeds (including instruments and writings) received by the Company in respect
of the Personal Property Collateral shall be received in trust for the benefit
of Fidelity hereunder, shall be segregated from other funds of the Company and
shall be promptly paid over to Fidelity in the same form as received (with any
necessary endorsement) to be applied in the same manner as payments received
directly by Fidelity.     

         Section 11. Power of Attorney. The Company grants to Fidelity an
irrevocable power of attorney coupled with an interest authorizing and
permitting Fidelity, at its option, with or without notice to the Company, to do
any or all of the following: (a) endorse the name of the Company on any checks
or other evidences of payment whatsoever that may come into the possession of
Fidelity regarding Personal Property Collateral, including checks received by
Fidelity pursuant to Section 10 hereof; (b) receive, open and forward any mail
addressed to the Company and put Fidelity's address on any statements mailed to
Account Debtors; (c) upon the occurrence of an Event of Default, pay, settle,
compromise, prosecute or defend any action, claim, conditional waiver and
release, or proceeding relating to Personal Property Collateral; (d) upon the
occurrence of an Event of Default, notify, in the name of the Company, the U.S.
Post Office to change the address for delivery of mail addressed to the Company
to such address as Fidelity may designate (provided that Fidelity shall turn
over to the Company all such mail not relating to Personal Property Collateral);
(e) upon the occurrence of an Event of Default, verify, sign, acknowledge,
record, file for recording, serve as required by law, any claim of mechanic's
lien, stop notice or bonded stop notice in the sole and absolute discretion of
Fidelity relating to any Personal Property Collateral; (f) upon the occurrence
of an Event of Default, insert all recording or service information in any
mechanic's lien or assignment of rights under stop notice/bonded stop notice
which the Company has signed in connection with this Agreement, recorded or
served to enforce payment of the Personal Property Collateral; (g) execute and
file on behalf of the Company any financing statement, amendment thereto or
continuation thereof (i) deemed necessary or appropriate by Fidelity to protect
Fidelity's interest in and to the Personal 

                                       20
<PAGE>
 
Property Collateral or (ii) required or permitted under any provision of this
Agreement; and (h) upon the occurrence of an Event of Default, do all other
things necessary and proper in order to carry out this Agreement. The authority
granted to Fidelity herein is irrevocable until this Agreement is terminated and
all amounts due to Fidelity hereunder have been paid in full.

         Section 12. Default. An event of default ("Event of Default") shall be
deemed to have occurred hereunder, Fidelity shall have no further obligation to
make any further Revolver Advances and may immediately exercise its rights and
remedies with respect to the Collateral under this Agreement, the Uniform
Commercial Code and applicable law, upon the happening of one or more of the
following:

         (a) The Company shall fail to pay as and when due any amount owed by
the Company to Fidelity, whether hereunder or otherwise.
    
         (b) The Company shall breach any covenant or agreement made herein or
in any other Transaction Document or any warranty or representation made herein
or in any other Transaction Document shall be untrue when made, and in either
case, the same shall not be cured to Fidelity's satisfaction within ten days
after such covenant or agreement is breached or such representation or warranty
is made; provided that if any such breach is impossible to remedy within ten
days, so long as the Company has undertaken (within the initial ten day cure
period) the steps necessary to remedy such breach and the Company diligently
continues to take all steps necessary to cure such failure, the ten day cure
period will be extended, but in no event shall the cure period exceed sixty
days.     

         (c) Any report, certificate, schedule, financial statement, profit and
loss statement or other statement furnished by the Company, or by any other
person on behalf of the Company, to Fidelity is not true and correct in any
material respect.

         (d) There shall be commenced by the Company or any guarantor of the
Obligations any voluntary case under the federal Bankruptcy Code, or the Company
or any guarantor of the Obligations shall make an assignment for the benefit of
its creditors, or of a receiver or custodian shall be appointed for the Company
or any guarantor of the Obligations for a substantial portion of its assets.

         (e) There shall be commenced against the Company or any guarantor of
the Obligations any involuntary case under the federal Bankruptcy Code, which
remains undismissed for a period of sixty days.

         (f) The Company shall become insolvent in that its debts are greater
than the fair value of its assets, or the Company is generally not paying its
debts as they become due.

         (g) Any involuntary lien, garnishment, attachment or the like shall be
issued against or shall attach to the Collateral and the same is not released
within ten days.

                                       21

any of its properties, or shall fail to pay any federal or state tax when due,

Section 412(a) of the Internal Revenue Code of 1986, as amended) in excess of
$25,000 exists with respect to any ERISA Plan, or (ii) any Termination Event
occurs with respect to any ERISA Plan and the then current value of such ERISA
Plan's benefit liabilities exceeds the then current value of such ERISA Plan's
assets available for the payment of such benefit liabilities by more than
$25,000.
    
         (k) The Company suffers the entry against it a final judgment for the

         (l) Fidelity believes that the prospect for payment or performance of

least 51% of the outstanding capital stock of the Company.

         
         
         
    
Upon the occurrence of an Event of Default described in subsections (d) or (e)
of this section, all of the Obligations owing by the Company to Fidelity under
any of the Transaction Documents shall thereupon be immediately due and payable,
without demand, presentment, notice of demand or of dishonor and nonpayment, or
any other notice or declaration of any kind, all of which are hereby expressly
waived by the Company. During the continuation of any other Event of Default,
Fidelity, at any time and from to time to time, may declare any or      

                                       22
<PAGE>
 
    
all of the Obligations owing by the Company to Fidelity under any of the
Transaction Documents immediately due and payable, all without notice, demand,
presentment, notice of demand or of dishonor and nonpayment, or any notice or
declaration of any kind, all of which are hereby expressly waived by the
Company. After any such acceleration (whether automatic or due to declaration by
Fidelity), any obligation of Fidelity to make any further Revolver Advances or
loans of any kind under this Agreement or any other agreement with the Company
shall terminate. All Revolver Advances hereunder are subject to approval by
Fidelity in its sole discretion, and may be declined in whole or in part,
without prior notice to the Company, whether or not an Event of Default may then
be in existence.     

         Section 13.   Remedies and Application of Proceeds.

         13.1. In addition to, and with limitation of, the foregoing provisions
of this Agreement, if an Event of Default shall have occurred and be continuing,
Fidelity may from time to time in its discretion, without limitation and without
notice except as expressly set forth herein: (A) exercise in respect of the
Collateral, in addition to other rights and remedies provided for herein, under
the other Transaction Documents or otherwise available to it, all the rights and
remedies of a secured party on default under the UCC (whether or not the UCC
applies to the affected Collateral); (b) require the Company to, and the Company
hereby agrees that it will at its expense, assemble all or part of the
Collateral as directed by Fidelity and make it available to Fidelity at a place
to be designated by Fidelity that is reasonably convenient to both parties; (c)
reduce its claim to judgment or foreclose or otherwise enforce, in whole or in
part, the security interest created hereby by any available judicial procedure;
(d) dispose of, at its office, on the premises or the Company or elsewhere, all
or any part of the Collateral, as a unit or in parcels, by public or private
proceedings; (e) buy the Collateral, or any part thereof, at any public sale, or
at any private sale if the Collateral is of a type customarily sold in a
recognized market or is of a type that is the subject to widely distributed
standard price quotations; (f) apply by appropriate judicial proceedings for
appointment of a receiver for the Collateral, or any part thereof, and the
Company hereby consents to any such appointment; and (g) at its discretion,
retain the Collateral in satisfaction of the Obligations whenever the
circumstances are such that Fidelity is entitled to do so under the UCC or
otherwise. The Company agrees that, to the extent notice of sale shall be
required by law, unless a longer period of notice is prescribed by law, at least
five days' notice to the Company of the time and place of any public sale or the
time after which any private sale is to be made shall constitute reasonable
notification. Fidelity shall not be obligated to make any sale of Collateral
regardless of whether any notice of sale has been given. Fidelity may adjourn
any public or private sale from time to time by announcement at the time and
place fixed therefor, and such sale may, without further notice, be made at the
time and place to which it was so adjourned.

         13.2. If any Event of Default shall have occurred and be continuing,
Fidelity may in its discretion apply any Cash Collateral, and any cash proceeds
received by Fidelity in respect of any sale of, collection from, or other
realization upon all or any part of the Collateral, to any or all of the
following in such order as Fidelity may elect: (a) the repayment of all or any
portion of the 

                                       23
<PAGE>
 
Obligations; (b) the repayment of reasonable costs and expenses, including
reasonable attorneys' fees and legal expenses, incurred by Fidelity in
connection with (i) the administration of this Agreement, (ii) the custody,
preservation, use or operation of, or the sale of, collection from, or other
realization upon, any Collateral, (iii) the exercise or enforcement of any of
the rights of Fidelity hereunder, or (iv) the failure of the Company to perform
or observe any of the provisions hereof; (c) the payment or other satisfaction
of any liens and other encumbrances upon any of the Collateral; (d) the
reimbursement of Fidelity for the amount of any obligations of the Company paid
or discharged by Fidelity, and of any expenses of Fidelity payable by the
Company hereunder or under the other Transaction Documents; (e) by holding the
same as Collateral; (f) the payment of any other amounts required by applicable
law (including, without limitation, Part 5 of Article 9 of the UCC or any
successor or similar applicable statutory provision); and (g) by delivery to the
Company or to whomsoever shall be lawfully entitled to receive the same or as a
court of competent jurisdiction shall direct.

         Section 14.   Miscellaneous.
    
         14.1. In the event that the Company commits any act or omission that
prevents or unreasonably interferes with (a) Fidelity's exercise of the rights
and privileges arising under the power of attorney granted in Section 11 of this
Agreement or (b) Fidelity's perfection of or levy upon the security interest
granted in the Collateral, including any seizure of any Collateral, the Company
acknowledges that such conduct will cause immediate, severe, incalculable and
irreparable harm and injury, and agrees that such conduct shall constitute
sufficient grounds to entitle Fidelity to an injunction, writ of possession, or
other applicable relief in equity, and to make such application for such relief
in any court of competent jurisdiction, without any prior notice to the 
Company.     
    
         14.2. All rights, remedies and powers granted to Fidelity in this
Agreement, or in any other instrument or agreement given by the Company to
Fidelity or otherwise available to Fidelity in equity or at law, are cumulative
and may be exercised singularly or concurrently with such other rights as
Fidelity may have. These rights may be exercised from time to time as to all or
any part of the Collateral as Fidelity in its discretion may determine. In the
event that Fidelity elects to purchase the Eligible Accounts hereunder, such
transaction shall constitute a purchase of Accounts under the UCC, and the
Company shall be deemed to have sold, assigned, transferred, conveyed and
delivered to Fidelity, as absolute owner, all of the rights, title and interest
of the Company in and to all Eligible Accounts. No waiver by Fidelity of its
rights and remedies shall be effective unless the waiver is in writing and
signed by Fidelity. A waiver by Fidelity of a right or remedy under this
Agreement or any other Transaction Document on one occasion shall not be deemed
to be a waiver of such right or remedy on any subsequent occasion. A Revolver
Advance by Fidelity during the-continuation of an Event of Default shall not
obligate Fidelity to make any further Revolver Advances during the continuation
of such Event of Default.     

                                       24
<PAGE>
 
    
         14.3. Any notice or communication with respect to this Agreement or any
other Transaction Document shall be given in writing, sent by (i) personal
delivery, (ii) expedited delivery service with proof of delivery, (iii) United
States mail, postage prepaid, registered or certified mail, or (iv) prepaid
telegram, telex or telecopy, addressed to each party hereto at its address set
forth below its signature hereon or to such other address or to the attention of
such other Person as hereafter shall be designated in writing by the applicable
party sent in accordance herewith. Any such notice or communication shall be
deemed to have been given either at the time of personal delivery or, in the
case of delivery service or mail, as of the date of first attempted delivery at
the address and in the manner provided herein, or in the case of telegram, telex
or telecopy, upon receipt The Company hereby agrees that Fidelity may publicize
the transaction contemplated by this Agreement in newspapers, trade and similar
publications including, without limitation, the publication of a 
"tombstone".     

         14.4. The term of this Agreement shall be for one year from the date
hereof (the original term, and any extension thereof made by Fidelity pursuant
to this section, are herein called the "Term"); provided, however, that Fidelity
may extend the term hereof for additional one-year periods, if Fidelity elects
to do so in its sole discretion, by notifying the Company in writing at least 30
days before the end of the term then in effect; and provided further that
Fidelity may terminate this Agreement at any time effective immediately upon the
occurrence of an Event of Default. The Company acknowledges that it shall have
no right to terminate this Agreement prior to the end of the Term, that
termination of this Agreement at any time prior to the end of the Term would
result in the loss by Fidelity of benefits under this Agreement and that the
damages incurred by Fidelity as a result of such termination would be difficult
and impractical to ascertain. Therefore, in the event this Agreement is
terminated prior to the end of the Term for any reason or the Fixed Asset Loan
is repaid in full (no termination fee shall be due solely as a result of the
prepayment of the Real Estate Loan), the Company shall pay to Fidelity an early
termination fee in an amount equal to (x) the average monthly accrued interest
and fees earned by Fidelity hereunder prior to the date of termination
multiplied by (y) the number of months remaining in the Term as of the date of
termination, but in no event shall such early termination fee exceed the maximum
amount permitted by applicable law. Any termination of this Agreement shall not
affect Fidelity's security interest in the Collateral, and this Agreement shall
continue to be effective, until all Obligations have been paid in full.

         14.5. Fidelity agrees that, so long as no Event of Default has occurred
and is continuing, upon receipt by Fidelity of payment in full of the
outstanding principal balance of the Real Estate Loan, together with interest
thereon, Fidelity shall at the expense of the Company execute and deliver such
instruments and documents as the Company may reasonably request to release the
Mortgage.
    
         14.6. Each and every provision, condition, covenant and representation
contained in this Agreement is, and shall be construed, to be a separate and
independent covenant and agreement. If any term or provision of this Agreement
shall to any extent be invalid or unenforceable, the remainder of the Agreement
shall not be affected thereby.     

                                       25
<PAGE>
 
         14 7. The Company hereby indemnifies and agrees to hold harmless and
defend all Indemnified Persons from and against any and all Indemnified Claims.
THE FOREGOING INDEMNIFICATION SHALL APPLY WHETHER OR NOT SUCH INDEMNIFIED CLAIMS
ARE IN ANY WAY OR TO ANY EXTENT OWNED, IN WHOLE OR IN PART, UNDER ANY CLAIM OR
THEORY OF STRICT LIABILITY, OR ARE CAUSED, IN WHOLE OR IN-PART, BY ANY NEGLIGENT
ACT OR OMISSION OF ANY INDEMNIFIED PERSON.
    
         If any Indemnified Claim is asserted against any Indemnified Person,
such Indemnified Person shall promptly notify the Company (but the failure to so
promptly notify the Company shall not affect the Company's obligations under
this section unless such failure materially prejudices the Company's right to
participate in the contest of such Indemnified Claim). The Company shall have
the obligation to assume the defense thereof, including the employment of
Advisors to take the lead role in asserting claims and defenses common to both
the Company and the various Indemnified Persons ("Lead Advisors"), provided that
all Persons chosen to be Lead Advisors must be consented to by Fidelity, which
consent will not be unreasonably withheld. If Lead Advisors are employed and
consented to in accordance with the preceding sentence, each Indemnified Person
shall nonetheless have the right to employ its own Advisors and to determine its
own defense of such action in any case, but the fees and expenses of such
Advisors shall be at the expense of such Indemnified Person except to the extent
that: (i) the employment of such Advisors shall have been authorized in writing
by the Company, or (ii) such Indemnified Person's counsel shall have reasonably
concluded that there appear to be claims or defenses available to it which are
not shared by the Company and such Advisors are engaged in reasonable efforts to
assert such claims and defense, in either of which events the reasonable fees
and expenses of such Indemnified Person shall be born by the Company. No
Indemnified Person shall settle or compromise any Indemnified Claim for which
the Company may be liable for payment hereunder nor shall the Company settle or
compromise any Indemnified Claim for which any Indemnified Person may be liable
for payments in addition to those actually and concurrently made by the Company,
without the consent of the other, which consent shall not be unreasonably
withheld. As used herein the term "Advisors" means attorneys, accountants,
experts, and other advisors.     

         Except as specifically provided in this section, the Company waives all
notices from any Indemnified Person. The provisions of this Section 14.7 shall
survive the termination of this Agreement.
    
         14.8. All grants, covenants and agreements contained in this Agreement
shall bind and inure to the benefit of the parties hereto and their respective
successors and assigns; provided, however, that the Company may not delegate or
assign any of its duties or obligations under this agreement without the prior
written consent of Fidelity. FIDELITY RESERVES THE RIGHT TO ASSIGN ITS RIGHTS
AND OBLIGATIONS UNDER THIS AGREEMENT IN WHOLE OR IN PART TO ANY PERSON OR
ENTITY. Without limiting the generality of the foregoing, Fidelity may from time
to time grant participations in all or any part      

                                       26
<PAGE>
 
    
of the Obligations to any Person on such terms and conditions as may be
determined by Fidelity in its sole and absolute discretion, provided that the
grant of such participation shall not relieve Fidelity of its obligations
hereunder nor create any additional obligation of the Company.     
    
         14.9. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED AND ENFORCED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF CALIFORNIA WITHOUT REFERENCE TO THE
RULES THEREFORE RELATING TO CONFLICTS OF LAW. THE COMPANY HEREBY IRREVOCABLY
SUBMITS ITSELF TO THE EXCLUSIVE JURISDICTION OF THE STATE AND FEDERAL COURTS
LOCATED IN CALIFORNIA AND AGREES AND CONSENTS THAT SERVICE OF PROCESS MAY BE
MADE UPON IT IN ANY LEGAL PROCEEDING RELATING TO THIS AGREEMENT, ANY BORROWING
HEREUNDER OR ANY OTHER RELATIONSHIP BETWEEN FIDELITY AND THE COMPANY BY ANY
MEANS ALLOWED UNDER STATE AND FEDERAL LAW. ANY LEGAL PROCEEDING ARISING OUT OF
OR IN ANY WAY RELATED TO THIS AGREEMENT, ANY BORROWING HEREUNDER OR ANY OTHER
RELATIONSHIP BETWEEN FIDELITY AND THE COMPANY SHALL BE BROUGHT AND LITIGATED
EXCLUSIVELY IN ANY ONE OF THE STATE OR FEDERAL COURTS LOCATED IN THE STATE OF
CALIFORNIA HAVING JURISDICTION. THE PARTIES HERETO HEREBY WAIVE AND AGREE NOT TO
ASSERT, BY WAY OF MOTION, AS A DEFENSE OR OTHERWISE, THAT ANY SUCH PROCEEDING IS
BROUGHT IN AN INCONVENIENT FORUM OR THAT THE VENUE THEREOF IS IMPROPER.     
    
         14.10. EACH OF THE COMPANY AND FIDELITY HEREBY (A) IRREVOCABLY WAIVES,
TO THE MAXIMUM EXTENT NOT PROHIBITED BY LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY
JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY AT ANY TIME ARISING OUT
OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT OR ANY TRANSACTION CONTEMPLATED
HEREBY OR ASSOCIATED HEREWITH; (B) IRREVOCABLY WAIVES, TO THE MAXIMUM EXTENT NOT
PROHIBITED BY LAW, ANY RIGHT IT MAY HAVE TO CLAIM OR RECOVER IN ANY SUCH
LITIGATION ANY SPECIAL, EXEMPLARY, PUNITIVE OR CONSEQUENTIAL DAMAGES, OR DAMAGES
OTHER THAN, OR IN ADDITION TO, ACTUAL DAMAGES; (C) CERTIFIES TEAT NO PARTY
HERETO NOR ANY REPRESENTATIVE OR AGENT OR COUNSEL FOR ANY PARTY HERETO HAS
REPRESENTED, EXPRESSLY OR OTHERWISE, OR IMPLIED THAT SUCH PARTY WOULD NOT, IN
THE EVENT OF LITIGATION, SEEK-TO ENFORCE THE FOREGOING WAIVERS, AND (D)
ACKNOWLEDGES THAT IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT AND THE
TRANSACTIONS CONTEMPLATED HEREBY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND
CERTIFICATIONS CONTAINED IN THIS PARAGRAPH.

         14.12. Fidelity hereby acknowledges that the Company is considering
incorporating the Company's divisions, INTERCON and INFOSEC, into separate
corporations and filing registration statements with the Securities and Exchange
Commission or other similar governmental authority. In the event the Company
proceeds with its plans to so incorporate and publicly register its divisions,
the Company and Fidelity shall enter into discussions concerning any waivers or
consents that may be required to effect such incorporation and public
registration.

G.7 352.229-9001 MD TAX EXEMPTION NUMBER (APR 1989)

     Certain transactions which occur pursuant to this contract, for examples,
the purchase of materials or supplies, may be exempt from the imposition of
state or local taxes. It is the contractor's responsibility to determine whether
any transactions under the contract are exempt under the particular tax statute
and to take advantage of any applicable exemptions. In addition, it may be
useful for the contractor to inform the taxing authorities that the Maryland
Procurement Office (MPO) is a federal government agency. In Maryland, it may be
useful to inform Maryland taxing authorities that the MPO has been assigned
Maryland State Tax Exemption Certificate Number 3000500 4.

                                (End of clause)

G.8 352.232-9025 NOTICE OF PROMPT PAYMENT ACT APPLICABILITY (OCT 1993)

                                (End of clause)

G.9 352.229-9000 NOTICE OF TAXATION (SEP 94)

     The Contractor shall provide the Contracting Officer with written notice of
any proposed tax assessments, exemptions, exclusions or refunds which could
increase or decrease costs or liabilities to the contractor and/or the
Government. The notice shall be submitted in sufficient time to provide the
Government a meaningful opportunity to assert its immunity, participate in
negotiations or litigation with the taxing authority concerning the
applicability of the tax, and/or adjust the parties' liability for costs
according to the increase or decrease in tax.

                                (End of Clause)

G.10 352.229-9001 CONTRACTOR LIABILITY FOR STATE AND LOCAL TAXES (SEP 1994)

     Generally, the contractor is liable for payment of state or local taxes on
this contract to the same extent that it would be liable for such taxes on a
contract with a non-governmental entity. Although it may be useful for the
contractor to inform the taxing authorities that the Maryland Procurement Office
(MPO) is a federal government agency, this fact alone does not in and of itself
create a tax exemption for the contractor. While some transactions undertaken by
the contractor pursuant to this contract may be exempt from a state or local
tax, it is the contractor's responsibility to identify such exemption under the

H.15 DELINQUENT AWARD FEE MODIFICATION PENALTY
    
   The Contracting Officer shall issue a contract modification identifying the
results of the fee determination official's findings for each performance
evaluation period in accordance with a schedule set forth in the current Award
Fee Plan as cited in the contract. If a contract modification is not issued in
compliance with the timeframe specified in the Award Fee Plan, the contractor
shall be entitled to interest on the determined award fee amount for that
specific period at the rate established by the secretary of the Treasury under
Section 12 of the Contract Disputes Act of 1978 (41 U.S.C. 611) that is in
effect on the modification issuance date. This rate is referred to as the
"Treasury Rate", and is published in the FEDERAL REGISTER semiannually or about
January 1 and July 1. The interest on any late award fee determination amount
will be calculated using the following formula from the first day after the
expiration of the timeframe specified in the current Award Fee Plan through the
actual date of the contract modification identifying what award fee has been
earned for that specific period. In the event that provisional billing has been
authorized under the contract, the Government shall only be liable for interest
on the balance between the final Award Fee determination for the specified
period and what has been authorized under the Provisional Billing clause.
Notwithstanding the above, the Government shall not be liable for any interest
penalty that is in excess of the sum total of the Award Fee available in the
current evaluation period and the unearned Award Fee from the prior evaluation
period at the time of the contract modification.     

   However, in the event that the Government has exercised an option or renewed
the contract into a subsequent fiscal year, where annual appropriations (O&M
funds) were utilized to fund the action, the Government's liability for any
interest penalty in the first evaluation period of that year shall be restricted
to the amount of the Award Fee available in the first evaluation period ONLY.
Subsequent Award Fee modifications for evaluation periods during that fiscal
year shall be subject to aforementioned terms where the Government's liability
for interest will be restricted to the sum total of the amount of Award Fee
available in the current evaluation period and the unearned Award Fee from the
prior evaluation period.

Current Treasury Rate % x No. of days Govt. is delinquent x (Amount of Award Fee
earned # of Annual Calendar Days (Beyond 60 Calendar Days) in the period -
Amount of Provisional Award Fee authorized for the period)

    
IF:     
Available Award Fee in the Period              $250,000
Amount authorized for Provisional Billing         50.00%  $125,000
Amount Earned in the Period                       90.00%  $225,000
Award Fee Plan Modification Time Frame                          60
Government Days Late (beyond 60 days)                           60
Current Treasury Rate                              5.50%


CALCULATION:
[(5.5% / 360) X 60] X (225,000 - 125,000) = 916.67

     (a)  Method of payment. Payments by the Government under this contract,
including invoice and contract financing payments, may be made by check or
electronic funds transfer (EFT) at the option of the Government. If payment is
made by EFT, the Government may, at its option, also forward the associated

information in terms acceptable to the payment office.
    
     (c)  Contractor's EFT information. Prior to submission of the first request
for payment (whether for invoice or contract financing payment) under this
contract, the Contractor shall provide the information required to make contract
payment by EFT, as described in paragraph (d) of this clause, directly to the

                                                                MDA904-97-C-0424
                                                                        24 of 34
     

the following information for both methods in a form acceptable to the
designated payment office. The Contractor may supply this data for this or
multiple contracts (sec paragraph (b) of this clause).

          (1)  The contract number to which this notice applies.

          (2)  The Contractor's name and remittance address, as stated in the
contract, and account number at the Contractor's financial agent.

          (3)  The signature (manual or electronic, as appropriate), title, and
telephone number of the Contractor official authorized to provide this
information.

          (4)  For ACH payments only:

                    (i)   Name, address, and 9-digit Routing Transit Number of
the Contractor's financial agent.

                    (ii)  Contractor's account number and the type of account
(checking, saving, or lockbox).

          (5)  For Federal Reserve Wire Transfer System payments only:

                    (i)   Name, address, telegraphic abbreviation, and the 9-
digit Routing Transit Number for the Contractor's financial agent.
    
                    (ii)  If the Contractor's financial agent is not directly 
on-line to the Federal Reserve Wire Transfer System and, therefore, not the
receiver of the wire transfer payment, the Contractor shall also provide the
name, address, and 9-digit Routing Transit Number of the correspondent financial
institution receiving the wire transfer payment.     

     (e)  Suspension of payment.

          (1)  Notwithstanding the provisions of any other clause of this
contract, the Government is not required to make any payment under this contract
until after receipt, by the designated payment office, of the correct EFT
payment information from the Contractor or a certificate submitted in accordance
with paragraph (b) of this clause. Until receipt of the correct EFT information,
any invoice or contract financing request shall be deemed not to be a valid
invoice or contact financing request as defined in the Prompt Payment clause of
this contract.

          (2)  If the EFT information changes after submission of correct EFT
information, the Government shall begin using the changed EFT information no
later than the 30th day after its receipt to the extent payment is made by EFT.
However, the Contractor may request that no further payments be made until the
changed EFT information is implemented by the payment office. If such suspension
would result in a late payment under the Prompt Payment clause of this contract,
the Contractor's request for suspension shall extend the due date for payment by
the number of days of the suspension.

                                                                        25 of 34
     

     (f)  Contractor EFT arrangements. The Contractor shall designate a single
financial agent capable of receiving and processing the electronic funds
transfer using the EFT methods described in paragraph (d) of this clause. The
Contractor shall pay all fees and charges for receipt and processing of
transfers.

     (g)  Liability for uncompleted or erroneous transfers.
    
          (1)  If an uncompleted or erroneous transfer occurs because the
Government failed to use the Contractor-provided EFT information in the correct
manner, the Government remains responsible for (i) making a correct payment,
(ii) paying any prompt payment penalty due, and (iii) recovering any erroneously
directed funds.     
    
          (2)  If an uncompleted or erroneous transfer occurs because 
Contractor-provided EFT information was incorrect at the time of Government
release of the EFT payment transaction instruction to the Federal Reserve
System, and-     

                    (i)  If the funds are no longer under the control of the
payment office, the Government is deemed to have made payment and the Contractor
is responsible for recovery of any erroneously directed funds; or

                    (ii) If the funds remain under the control of the payment
office, the Government retains the right to either make payment by mail or
suspend the payment in accordance with paragraph (e) of this clause.

     (h)  EFT and prompt payment.

          (1)  A payment shall be deemed to have been made in a timely manner in
accordance with the Prompt Payment clause of this contract if, in the EFT
payment transaction instruction given to the Federal Reserve System, the date
specified for settlement of the payment is on or before the prompt payment due
date, provided the specified payment date is a valid date under the rules of the
Federal Reserve System.

          (2)  When payment cannot be made by EFT because of incorrect EFT
information provided by the Contractor, no interest penalty is due after the
date of the uncompleted or erroneous payment transaction, provided that notice
of the defective EFT information is issued to the Contractor within 7 days after
the Government is notified of the defective EFT information.
    
                    (i)  EFT and assignment of claims. If the Contractor assigns
the proceeds of this contract as provided for in the Assignment of Claims clause
of this contract, the assignee shall provide the assignee EFT information
required by paragraph (d) of this clause. In all respects, the requirements of
this clause shall apply to the assignee as if it were the Contractor. EFT
information which shows the ultimate recipient of the transfer to be other than
the Contractor, in the absence of a proper assignment of claims acceptable to
the Government, is incorrect EFT information within the meaning of paragraph (e)
of this clause.     

     (j)  Payment office discretion. If the Contractor does not wish to receive
payment by EFT methods for one or more payments, the Contractor may submit a
request to the designated

payment office to refrain from requiring EFT information or using the EFT
payment method. The decision to grant the request is solely that of the
Government.
    
     (k)  Change of EFT information by financial agent. The Contractor agrees
that the Contractor's financial agent may notify the Government of a change to
the routing transit number, Contractor account number, or account type. The
Government shall use the changed data in accordance with paragraph (e)(2) of
this clause. The Contractor agrees that the information provided by the agent is
deemed to be correct information as if it were provided by the Contractor. The
Contractor agrees that the agent's notice of changed EFT data is deemed to be a
request by the Contractor in accordance with paragraph (e)(2) that no further
payments be made until the changed EFT information is implemented by the payment
office.

     Funds in the amount of $42,279.50 Section B.2, and $25,971.50, Section B.3,
have been obligated under this con  tract towards future award fee
determinations but are not available for the Contractor to bill against or incur

the Contractor via subsequent modifications after the Government has rendered an
award fee determination in accordance with the Award Fee Plan currently in force
under this contract. Upon receipt of the aforementioned modifications, the
Contractor is authorized to bill for the earned fee.     
    
G.14 METHOD OF INVESTMENT CALCULATION / INVOICING (applicable to Section B.3
only)     
    
     The Contractor agrees that it will make an investment of 45% of total costs
incurred up to a maximum investment contribution of $721,890.00. In order to
implement this investment, the Contractor agrees that each of its invoices for
incurred costs on the effort contained in Section B.3 will include the following
information:     

               Total costs incurred
               55% of those costs charged to the Government
               45% of those costs charged to the Contractor
               Total amount to be paid by the Government
               Total investment to date by Contractor
    
It is further agreed by the parties that, once the maximum investment is
reached, any additional costs incurred above the estimated costs contained
herein that are otherwise allowable, allocable, and reasonable and in accordance
with the other provisions of the contract, will be invoiced up to a total of
$1,515,890.00, which total includes the contractor's maximum investment of
$721,890.00, and the government's investment of $794,000.00 for the current
period of performance. The contractor's maximum investment is $721,890.00. All
invoices will be paid in accordance with the payment provisions stated in this
contract.  In no case will the contractor invoice the government for more than
the Not-To-Exceed amount listed in the contract. The Contractor shall notify the
Contracting Officer in writing whenever it has reason to believe that the costs
it expects to incur under this contract in the next 60 days, when added to all
costs previously incurred, will exceed 75 percent of the amount currently
obligated on the contract. The Contractor's notice shall include an estimate of
funds required to continue performance. If, after notification by the Contractor
pursuant to this clause, additional funds are required to be obligated for a
further period, the government will negotiate an appropriable resolution.

The Performance Evaluation Board discussed Litronic, Inc.'s performance during
the base year award fee period via informal meetings. The conclusions reached
are summarized as follows.

TECHNICAL
Staffing:
 .  Skilled personnel were assigned to the task, and all subcontracts appear to
have been well managed.
 .  There were no problems with personnel equipped with inadequate skills working
on the task.
Rating:  EXCELLENT

PERFORMANCE:
 .  System Engineering produced a flexible architecture that was able to respond
to numerous problems.
    
 .  Few of the many bugs in the CI Library 1.52b were the result of any
deficiency in Litronic's test engineering process. While Litronic's Software
Engineering Process has some way to go, it certainly was capable of responding
to this particular debugging exercise.     
 .  Litronic is very responsive in addressing support concerns.
 .  Litronic communicates problems and concerns very well with the Program
Office.
Rating:  EXCELLENT
    
SCHEDULE:     
    
 .  Contractor had some difficulty in meeting schedule for CI Library 1.52b. As a
result, library release was delayed for several months.     
Rating:  MARGINAL

COST
 .  Litronic effectively controlled program costs.
 .  No problems were evident in Litronic's billing procedures.
 .  Status reporting is deficient. It is often late, not available, or not
useful. If this problem is not corrected by the next evaluation period, cost
will be further affected.

                     SECURE TELECOMMUNICATION REQUIREMENTS

Secure telecommunications are required as this contract involves access to
classified information or sensitive unclassified, Government or Government-
derived information at the contractor facility. These requirements apply to the
use of Government contractor telecommunications equipment over which classified
information or sensitive unclassified Government or Government-derived
information is transmitted.

The following definitions apply:

processing of information (writing, images, sounds or other data) by electrical
electromagnetic, electromechanical, electro-optical or electronic means.

"Government Contractor" telecommunications:  Voice and data telecommunications
between or among Federal Government Agencies and their
contractor/subcontractors. This includes management information processing
systems and local data networks.

"Secured" means the application of communications security (COMSEC) equipments,
devices or techniques to telecommunications or information processing systems
over which classified information is transmitted.

"Protected" means the application of National Security Agency (NSA) approved
protection equipment, devices or techniques to contractor telecommunications
over which sensitive unclassified, Government or Government-derived information
is transmitted.

"Sensitive unclassified, Government or Government derived information" is
defined as any information, the loss, misuse or unauthorized access to, or
modification of which might adversely affect the U.S. national interest, the
conduct of DoD programs or the privacy of DoD personnel.

A COMSEC account is required for this contract. The NSA Central Office of Record
has primary responsibility for auditing all COMSEC material held in this
account. NSA will ensure that all Government contractor secure
telecommunications facilities are operated in accordance with NSA requirements.

                         COLLATERAL (NON-SCI) CONTRACTS

Contractor employees may not carry any classified material on commercial
aircraft unless approved by the Contracting Officer (CO) or his designated
representative.

Classified material released under this contract does not become the property of
the contractor and can be withdrawn by the National Security Agency (NSA) at
anytime. Upon expiration of the contract, all classified materials released to
the contractor and all other materials of any kind incorporating data from such
classified materials will be returned to the NSA for final disposition. A
certificate of destruction in lieu of the material will suffice when the
material has been destroyed, either at the direction or under the supervision of
the CO or his designee.

The contractor will not release classified material to any activity or
individual of the contractor's organization not directly engaged in providing
services under the contract, or to another contractor (including a
subcontractor), government agency, private individual, or organization without
the written consent of the CO. In the event that consent for such release is
requested, the NSA will verify that the proposed recipient is appropriately
cleared and has need-to-know.

Contractor and subcontractor personnel, as well as individuals who are
consultants to the contractor or subcontractor, who have access to certain
specified classified cryptographic information or materials, or to spaces where
such classified cryptographic information or materials are produced, processed
or stored are subject to requirements set forth in NSA/CSS Regulation 90-15. The
Contractor Security Officer shall notify such personnel that they are subject to
this requirement and shall provide the CO written confirmation that this notice
was provided within 90 days of the effective date of this DD254.

Non-US citizens, to include immigrant aliens, are not authorized access to
classified or to unclassified portions of this contract, proposal or study
without the express written approval of NSA, Facilities Security Services (S41).

Contractors will maintain such records as will permit them to furnish on demand
the names of individuals who have or have had access to classified material in
the custody of the contractor.
 
Reproduction of any material released to the contractor must be approved by the
Contracting Officer's Representative (COR).

                                   SUBLEASE 

NOTE:  This Sublease document is being used as a Sub-sublease document.
Therefore, the terms "sublease", "sublessor" and "sublessee" will often be used
as "sub-sublease", "sub-sublessor" and sub-sublessee", respectively.

1.   PARTIES.

This Sublease, dated October 20, 1997, is made between E.I. du Pont de Nemours
and Company, a Delaware corporation (Sublessor"), and Lintronic Industries, a
California corporation ("Sublessee").

2.   MASTER LEASE.

Sublessor is the Sub-lessee under a written lease dated February 21, 1991,
wherein Koll Tower Four Associates, a California limited partnership ("Lessor")
leased to Lessee Hadson Power Systems, a Delaware corporation, the real property
located in the City of Irvine, County of Orange, State of California, described
as portions of that certain 16-story office building located at 2030 Main
Street, Irvine, California, as identified in the Master Lease as the "Premises"
("Master Premises").  Said lease has been amended by the following amendments
that certain Sublease dated April 7, 1995 by and between Hadson Power Systems
("Hadson")*, a Delaware corporation and E.I. du Pont de Nemours and Company (as
existing "Sublessor"); said lease and amendments are herein collectively
referred to as the "Master Lease" and are attached hereto as Exhibit "A".

3.   PREMISES.

Sublessor hereby subleases to Sublessee on the terms and conditions set forth in
this Sublease the following portions of the Master Premises ("Premises"):
approximately 11.912 rentable square feet as identified as Exhibit One to the
sublease and further identified as 2030 SE Main Street, Suite 1250, Irvine,
California.

4.   WARRANTY BY SUBLESSOR.

Sublessor warrants and represents that the Master Lease has not been amended or
modified except as expressly set forth herein, that Sublessor is not now, and as
of the commencement of the Term hereof will not be, in default or breach of any
of the provisions of the Master Lease, and that Sublessor has no knowledge of
any claim by Lessor that Sublessor is in default or breach of any of the
provisions of the Master Lease.

5.   TERM.

The Term of this Sublease shall commence on November 1, 1997 ("Commencement
Date"), or when Lessor consents to this Sublease (if such consent is required
under the Master Lease), whichever shall last occur, and end on September 17,
2001 ("Termination Date"), unless otherwise sooner terminated in accordance with
the provisions of this Sublease. In the event the Term commences on a date other
than the Commencement Date, Sublessor and Sublessee shall execute a memorandum
setting forth the actual date of the commencement of the Term. 
     
<PAGE>
 
    
Possession of the Premises ("Possession") shall be delivered to Sublessee on the
commencement of the Term. If for any reason Sublessor does not deliver
Possession to Sublessee on the commencement of the Term, Sublessor shall not be
subject to any liability for such failure, the Termination Date shall not be
extended by the delay, and the validity of this Sublease shall not be impaired,
but rent shall abate until delivery of Possession. Notwithstanding the
foregoing, if Sublessor has not delivered Possession to Sublessee within thirty
(30) days after the Commencement Date, then at any time thereafter and before
delivery of Possession, sublessee may give written notice to Sublessor of
Sublessee's intention to cancel this Sublease.  Said notice shall set forth an
effective date for such cancellation which shall be at least ten (10) days after
delivery of said notice to Sublessor.  If Sublessor delivers Possession to
Sublessee on or before such effective date, this Sublease shall remain in full
force and effect. If Sublessor fails to deliver Possession to Sublessee on or
before such effective date, this Sublease shall be cancelled, in which case all
consideration previously paid by Sublessee to Sublessor on account of this
Sublease shall be returned to Sublessee, this Sublease shall thereafter be of no
further force and effect, and Sublessor shall have no further liability to
Sublessee on account of such delay or cancellation. If Sublessor permits
Sublessee to take Possession prior to the commencement of the Term, such early
Possession shall not advance the Termination Date and shall be subject to the
provisions of this Sublease, including without limitation the payment of rent.

6.    RENT.

6.1.  Minimum Rent.  Sublessee shall pay to Sublessor as minimum rent, without
deduction, setoff, notice, or demand, at E.I. du Pont de Nemours, Attn:
Corporate Real Estate, 1007 Market Street, D12048A, Wilmington, DE 19898, or at
such other place as Sublessor shall designate from time to time by notice to
Sublessee, the sum of See Addendum One Dollars ($_________) per month, in
advance on the first day of each month of the Term. Sublessee shall pay to
Sublessor upon execution of this Sublease the sum of Twenty Thousand Two Hundred
Fifty and 40/100ths Dollars ($20,250.40) as rent for the first month. If the
Term begins or ends on a day other than the first or last day of a month, the
rent for the partial months shall be prorated on a per diem basis. Additional
provisions: See attached Addendum One

6.2.  Operating Costs.  If the Master Lease requires Sublessor to pay to Lessor
all or portion of the expenses of operating the building and/or project of which
the Premises are a part ("Operating Costs"), including but not limited to taxes,
utilities, or insurance, then Sublessee shall pay to Sublessor as additional
rent seventy and 24/100ths percent (70.24%) of the amounts payable by Sublessor
for Operating Costs incurred during the Term. Such [illegible text] shall be
payable as and [illegible text] Operating Costs are payable by Sublessor to
Lessor if the Master Lease provides for the payment by Sublessor of Operating
Costs on the basis of an estimate thereof, then as and when adjustments when
estimated and actual Operating Costs are made under the Master Lease, the
obligations of Sublessor and Sublessee hereunder shall be adjusted in a like
manner, and if any such adjustment shall occur after the expiration of 
     

                                       2
<PAGE>
 
    
earlier termination of the term, then the obligations of Sublessor and Sublessee
under this Section 6.2 shall survive such expiration or termination. Sublessor
shall, upon request by Sublessee, furnish Sublessee with copies of all
statements submitted by Lessor of actual or estimated Operating Costs during the
Term.

7.   SECURITY DEPOSIT.

Sublessee shall deposit with Sublessor upon execution of this Sublease the sum
of Twenty Thousand Two Hundred Fifty and 40/100ths Dollars ($20,250.40) as
security for Sublessee's faithful performance of Sublessee's obligations
hereunder ("Security Deposit"). If Sublessee fails to pay rent or other charges
when due under this Sublease, or fails to perform any of its other obligations
hereunder, Sublessor may use or apply all or any portion of the Security Deposit
for the payment of any rent or other amount then due hereunder and unpaid, for
the payment of any other sum for which Sublessor may become obligated by reason
of Sublessee's default or breach, or for any loss or damage sustained by
Sublessor as a result of Sublessee's default or breach. If Sublessor so uses any
portion of the Security Deposit, Sublessee shall, within ten (10) days after
written demand by Sublessor, restore the Security Deposit to the full amount
originally deposited, and Sublessee's failure to do so shall constitute a
default under this Sublease. Sublessor shall not be required to keep the
Security Deposit separate from its general accounts, and shall have no
obligation or liability for payment of interest on the Security Deposit. In the
event Sublessor assigns its interest in this Sublease, Sublessor shall deliver
to its assignee so much of the Security Deposit as is then held by Sublessor.
Within ten (10) days after the Term has expired, or Sublessee has vacated the
Premises, or any final adjustment pursuant to Subsection 6.2 hereof has been
made, whichever shall last occur, and provided Sublessee is not then in default
of any of its obligations hereunder, the Security Deposit, or so much thereof as
had not theretofore been applied by Sublessor, shall be returned to Sublessee or
to the last assignee, if any, of Sublessee's interest hereunder.

8.   USE OF PREMISES.

The Premises shall be used and occupied only for sales, consulting and related
general office functions, and for no other use or purpose.

9.   ASSIGNMENT AND SUBLETTING.

Sublessee shall not assign this Sublease or further sublet all or any part of
the Premises without the prior written consent of Sublessor (and the consent of
Lessor, if such is required under the terms of the Master Lease).

10.  OTHER PROVISIONS OF SUBLEASE.

All applicable terms and conditions of the Master Lease are incorporated into
and made a part of this Sublease as if Sublessor were the lessor thereunder,
Sublessee the lessee thereunder, and the Premises the Master Premises, except
for the following:

See attached Addendum One to the Sublease

Sublessee assumes and agrees to perform the lessee's obligations under the
Master Lease during the Term to the extent that such obligations are applicable
to the Premises, except that the 
     

                                       3
<PAGE>
 
    
obligation to pay rent to Lessor under the Master Lease shall be considered
performed by Sublessee to the extent and in the amount rent is paid to Sublessor
in accordance with Section 6 of this Sublease. Sublessee shall not commit or
suffer any act or omission that will violate any of the provisions of the Master
Lease. Sublessor shall exercise due diligence in attempting to cause Lessor to
perform its obligations under the Master Lease for the benefit of Sublessee. If
the Master Lease terminates, this Sublease shall terminate and the parties shall
be relieved of any further liability or obligation under this Sublease, provided
however, that if the Master Lease terminates as a result of a default or breach
by Sublessor or Sublessee under this Sublease and/or the Master Lease, then the
defaulting party shall be liable to the nondefaulting party for the damage
suffered as a result of such termination. Notwithstanding the foregoing, if the
Master Lease gives Sublessor any right to terminate the Master Lease in the
event of the partial or total damage, destruction, or condemnation of the Master
Premises or the building or project of which the Master Premises are a part, the
exercise of such right by Sublessor shall not constitute a default or breach
hereunder.

11.  ATTORNEYS' FEES

arising out of or in connection with this Sublease, the prevailing party shall
be entitled to recover its costs of suit and reasonable attorney's fees.

Agreement, on and after the Closing Date to but not including the date that is
the earlier of (x) the date on which this Agreement is terminated pursuant to
Section 10. and (y) the date on which IBM Credit terminates the Credit Line
pursuant to Section 9.,  IBM Credit agrees to extend to the Customer a credit
line ("Credit Line") in the amount set forth the Attachment A pursuant to which
IBM Credit will make to the Customer, from time to time, Advances in an
aggregate amount at any one time outstanding not to exceed the Maximum Advance
Amount.  Notwithstanding any other term or provision of this Agreement, IBM
Credit may, at any time and from time to time, in its sole discretion (x)
temporarily increase the amount of the Credit Line above the amount set forth in
Attachment A and decrease the amount of the Credit Line back to the amount of
the Credit Line set forth in Attachment A, in each case upon written notice to
the Customer and (y) make Advances pursuant to this Agreement upon the request
of Customer in an aggregate amount at any one time outstanding in excess of the
Credit Line.

2.2.  Product Advances.  (A)  Subject to the terms and conditions of this
Agreement, IBM Credit shall make Product Advances in connection with Customer's
purchase of Products from Authorized Suppliers (as defined under WITNESSETH).
Customer hereby authorizes and directs IBM Credit to pay the proceeds of Product
Advances directly to the applicable Authorized Supplier in respect of invoices
delivered to IBM Credit for such Products by such Authorized Supplier and
acknowledges that each such Product Advance constitutes a loan by IBM Credit to
Customer pursuant to this Agreement as if the Customer received the proceeds of
the Product Advance directly from IBM Credit.

  (B)  No finance charge shall accrue on any Product Advance during the Free
Financing Period, if any, applicable to such Product Advance.  Customer shall
repay each Product Advance no later than the Common Due Date for such Product
Advance.  Customer may, at its option, repay each Product Advance by requesting
IBM Credit to apply all or any part of the principal amount of an A/R Advance to
the Outstanding Product Advances.  Customer's request for such application shall
be made in accordance with Section 2. When so requested and subject to the terms
and conditions of this Agreement, IBM Credit shall apply the amount so requested
to the amounts due in respect of the Outstanding Product Advances. Nothing

                                 Page 12 of 46
<PAGE>
 
contained herein shall relieve Customer of its obligation to repay Product
Advances when due. Each Product Advance shall accrue a finance charge on the
Average Daily Balance thereof from and including the first (1st) day following
the end of the Free Financing Period, if any, for such Product Advance, or if no
such Free Financing Period shall be in effect, from and including the date of
invoice for such Product Advance, in each case, to and including the date such
Product Advance shall become due and payable in accordance with the terms of
this Agreement, at a per annum rate equal to the lesser of (a) the finance
charge set forth in Attachment A to this Agreement as the "Product Financing
Charge" and (b) the highest rate from time to time permitted by applicable law.

In addition, for any Product Advance with respect to which a Free Financing
Period shall not be in effect, Customer shall pay a Free Financing Period
Exclusion Fee.  Such fee shall be due and payable on the Common Due Date for
such Product Advance.  If it is determined that amounts received from Customer
were in excess of the highest rate permitted by law, then the amount
representing such excess shall be considered reductions to principal of
Advances.

  (C)  Customer acknowledges that IBM Credit does not warrant the Collateral.
Customer shall be obligated to pay IBM Credit in full even if the Collateral is
defective or fails to conform to the warranties extended by the Authorized
Supplier.  The Obligations of Customer shall not be affected by any dispute
Customer may have with any manufacturer, distributor or Authorized Supplier.
Customer will not assert any claim or defense which it may have against any
manufacturer, distributor or Authorized Supplier against IBM Credit.

  (D)  Customer hereby authorizes IBM Credit to collect directly from any
Authorized Supplier any credits, rebates, bonuses or discounts owed by such
Authorized Supplier to Customer ("Supplier Credits").  Any Supplier Credits
received by IBM Credit may be applied by IBM Credit to the Outstanding Advances.
IBM Credit will use its best efforts to provide a schedule of Supplier Credits
to Customer weekly or upon Customer's reasonable demand.  Any Supplier Credits
collected by IBM Credit shall in no way reduce Customer's debt to IBM Credit in
respect of the Outstanding Advances until such Supplier Credits are applied by
IBM Credit.

  (E)  IBM Credit may apply any payments and Supplier Credits received  by
IBM Credit to reduce finance charges first and then to principal amounts of
Advances owed by Customer.  IBM Credit may apply principal payments to the
oldest (earliest) invoices (and related Product Advances) first, but, in any
case, all principal payments will be applied in respect of the Outstanding
Product Advances made for Products which have been sold, lost, stolen,
destroyed, damaged or otherwise disposed of prior to any other application
thereof.

  (F)  Customer will indemnify and hold IBM Credit harmless from and against
any claims or demands asserted by any Person relating to or arising from the
Collateral for any reason whatsoever, including, without limitation, the
condition of the Collateral, any misrepresentation made about the Collateral by
any representative of

                                 Page 13 of 46
<PAGE>
 
Customer, or any act or failure to act by Customer except to the extent such
claims or demands are directly attributable to IBM Credit's gross negligence or
willful misconduct.  Nothing contained in the foregoing shall impair any rights
or claims which the Customer may have against any manufacturer, distributor or
Authorized Supplier.

2.3.  A/R Advances.  (A) Whenever Customer shall desire IBM Credit to provide an
A/R Advance, Customer shall deliver to IBM Credit written notice of Customer's
request for such an Advance ("Request for A/R Advance").  For any requested A/R
Advance pursuant to which monies will be disbursed to Customer or any Person
other than IBM Credit, a Request for A/R Advance shall be delivered to IBM
Credit on or prior to 1:00 p.m. (eastern time) one Business Day prior to the
requested A/R Advance Date.  The Request for A/R Advance shall specify (i) the
requested A/R Advance Date; (ii) the amount of the requested A/R Advance; (iii)
whether such A/R Advance is a WCO Advance or a PRO Advance; (iv) if applicable,
the PRO Advance Term for such A/R Advance; (v) for each PRO Advance, the month,
day and year of the Common Due Date, as set forth in Customer's applicable
billing statement from IBM Credit, for the Product Advance to which the PRO
Advance is to be applied; and (vi) if applicable, the amount of the requested
A/R Advance that should be applied to the Outstanding Product Advances (provided
that all PRO Advances shall be applied to the Outstanding Product Advances).
Customer may deliver a Request for A/R Advance via facsimile.  Any Request for
A/R Advance delivered to IBM Credit shall be irrevocable.  Notwithstanding any
other provision of this Agreement, Customer shall not (i) request more than one
PRO Advance in respect of any Product Advance; and (ii) request a PRO Advance
for any Common Due Date on which Customer will take a discount offered by IBM
Credit for invoice amounts paid in full within fifteen days of the invoice date
under IBM Credit's High Turnover Option ("HTO") Program.
    
  (B)  Subject to the terms and conditions of this Agreement, on the A/R
Advance Date specified in a Request for A/R Advance, IBM Credit shall make the
principal amount of each A/R Advance available to the Customer in immediately
available funds to an account maintained by Customer (or in the case of a
Takeout Advance, as directed by Customer).  If IBM Credit is making an A/R
Advance hereunder on a day on which Customer is to repay all or any part of an
Outstanding Advance (or any other amount owing hereunder), IBM Credit shall
apply the proceeds of the A/R Advance to such repayment and only an amount equal
to the difference, if any, between the amount of the A/R Advance and the amount
being repaid shall be made available to Customer as provided in the immediately
preceding sentence.     

  (C)  Each A/R Advance shall accrue a finance charge on the unpaid principal
amount thereof, from and including the date of each A/R Advance to and including
the date such A/R Advance is due and payable in accordance with the terms of
this Agreement at a per annum rate equal to the lesser of (a) the finance charge
set forth in Attachment A to this Agreement under the caption "A/R Finance
Charge" for such type of A/R Advance, or (b) the highest rate from time to time
permitted by applicable law.  If it is determined that amounts received from the
Customer were in excess of such highest rate, then the amount

                                 Page 14 of 46
<PAGE>
 
representing such excess shall be considered reductions to principal of
Advances.

  (D) Unless otherwise due and payable at an earlier date, the unpaid
principal amount of each A/R Advance, other than a Takeout Advance, shall be due
and payable on the applicable Common Due Date.  Unless otherwise notified by
Customer in writing prior to the day the principal amount of any WCO Advance
becomes due and payable, the customer shall be deemed to have provided IBM
Credit with a Request for A/R Advance requesting a WCO Advance on the day such
principal amount is due and payable in an amount equal to the unpaid principal
amount of the WCO Advance so due.  Subject to the terms and conditions of this
Agreement, the principal amount of such WCO Advance shall automatically renew
for an additional WCO Advance Term.  Notwithstanding any other provision of this
Agreement, a Takeout Advance may only be requested on the Closing Date and such
Takeout Advance shall be limited to an amount sufficient to discharge the
indebtedness that is the subject of a Takeout Advance.

Unless otherwise agreed in writing, a Takeout Advance shall be due pursuant to
the Schedule of Repayments in Attachment D to this Agreement.

2.4.  Finance and Other Charges.  (A) Finance charges shall be calculated by
multiplying the applicable Delinquency Fee Rate, Product Financing Charge or A/R
Finance Charge provided for in this Agreement by Customer's applicable Average
Daily Balance.  The Delinquency Fee Rate, the Product Financing Charge and the
various A/R Finance Charges provided for in this Agreement are each computed on
the basis of an actual day, 360 day year.

  (B) The Customer hereby agrees to pay to IBM Credit the charges set forth
as "Other Charges" in Attachment A.  The Customer also agrees to pay IBM Credit
additional charges for any returned items of payment received by IBM Credit.
The Customer hereby acknowledges that any such charges are not interest but that
such charges, if unpaid, will constitute part of the Outstanding Advances.

  (C) The finance charges and Other Charges owed under this Agreement, and
any charges hereafter agreed to in writing by the parties, are payable monthly
on receipt of IBM Credit's bill or statement therefor or IBM Credit may, in its
sole discretion, add unpaid finance charges and Other Charges to the Customer's
outstanding Advances.

  (D) If any amount owned under this Agreement, including, without
limitation, any Advance, is not paid when due (whether at maturity, by
acceleration or otherwise), the unpaid amount thereof will bear a late charge
from and including the day after such Advance was due and payable to and
including the date IBM Credit receives payment thereof, at a per annum rate
equal to the lesser of (a) the amount set forth in Attachment A to this
Agreement as the "Delinquency Fee Rate" and (b) the highest rate from time to
time permitted by applicable law.  In addition, if any Shortfall Amount shall
not be paid when due pursuant to Section 2.6 hereof, Customer shall pay IBM
Credit a Shortfall Transaction Fee.  If

                                 Page 15 of 46
<PAGE>
 
    
it is determined that amounts received from Customer were in excess of such
highest rate, then the amount representing such excess shall be considered
reductions to principal of Advances.
     

2.5 Statements Regarding Customer's Account.  IBM Credit will send statements of
each transaction hereunder as well as monthly billing statements to Customer
with respect to Advances and other charges due on Customer's account with IBM
Credit.  Each statement of transaction and monthly billing statement shall be
deemed, absent manifest error, to be correct and shall constitute an account
stated with respect to each transaction or amount described therein unless
within seven (7) Business Days after such statement of transaction or billing
statement is received by Customer, Customer provides IBM Credit written notice
objecting that such amount or transaction is incorrectly described therein and
specifying the error(s), if any, contained therein.  IBM Credit may at any time
adjust such statements of transaction or billing statements to comply with
applicable law and this Agreement.

2.6.  Shortfall.  If, on any date, the Outstanding Advances shall exceed the
Maximum Advance Amount (such excess, the "Shortfall Amount"), then the Customer
shall on such date prepay the Outstanding Advances in an amount equal to such
Shortfall amount.

2.7.  Application of Payments.  The Customer hereby agrees that all checks and
other instruments delivered to IBM Credit on account of Customer's Obligations
shall constitute conditional payment until such items are actually collected by
IBM Credit.  The Customer waives the right to direct the application of any and
all payments at any time or times hereafter received by IBM Credit on account of
the Customer's Obligations.  Customer agrees that IBM Credit shall have the
continuing exclusive right to apply and reapply any and all such payments to
Customer's Obligations in such manner as IBM Credit may deem advisable
notwithstanding any entry by IBM Credit upon any of its books and records.

2.8.  Prepayment and Reborrowing By Customer.  (A) Customer may at any time
prepay, without notice or penalty, in whole or in part amounts owed under this
Agreement.  IBM Credit may apply payments made to it (whether by the Customer or
otherwise) to pay finance charges and other amounts owing under this Agreement
first and then to the principal amount owed by the Customer.

  (B) Subject to the terms and conditions of this Agreement, any amount
prepaid or repaid to IBM Credit in respect to the Outstanding Advances may be
reborrowed by Customer in accordance with the provisions of this Agreement.

The aggregate of all Accounts that are not ineligible Accounts shall hereinafter

of proceeds of the Advances hereunder.

lockbox ("Lockbox") at the address set forth in Attachment A

                                 Page 18 of 46
<PAGE>

IBM Credit. Customer shall also establish and maintain a deposit account which
shall contain only proceeds of Customer's Accounts ("Special Account") with such

any deposits of funds other than remittances paid in respect of the Accounts
into the Special Account(s) or permit any commingling of funds with such
remittances in any Lockbox or Special Account.  Without limiting the Customer's
foregoing obligations, if, at any time, Customer receives a remittance directly
from an Account debtor, then Customer shall make entries on its books and
records in a manner that shall reasonably identify such remittances and shall
keep a separate account on its record books of all remittances so received and
deposit the same into a Special Account.  Until so deposited into the Special
Account, Customer shall keep all remittances received in respect of Accounts
separate and apart from Customer's other property so that they are capable of

interest.

3.5.  Application of Remittances and Credits.  Customer shall apply all
remittances against the aggregate of Customer's outstanding Accounts no later
than the end of the Business Day on which such remittances are deposited into
the Special Account.  Customer also agrees to apply each remittance against its

shall deem necessary or appropriate to perfect and maintain perfected the

  (N) make, settle and adjust claims under the Policies with respect to the
Collateral and endorse Customer's name on any check, draft, instrument or other
item of payment of the proceeds of the Policies with respect to the Collateral;
and

  (O) take control in any manner of any term of payment or proceeds and for such
purpose to notify the postal authorities to change the address for delivery of
mail addressed to Customer to such address as IBM Credit may designate.

The power of attorney granted by this Section is for value and coupled with an
interest and is irrevocable so long as this Agreement is in effect or any
Obligations remain outstanding. Nothing done by IBM Credit pursuant to such
power of attorney will reduce any of Customer's Obligations other than
Customer's payment Obligations to the extent IBM Credit has received monies.

any change in the location of any Collateral, the location of its books and
records or in the location of its chief executive office or place of business
from the locations specified in Attachment B, and will execute in advance of

against other business risks, in each case, in at least such amounts and against

                                 Page 32 of 46

request, the insurance certificates with respect to such insurance. In addition,

than the amount set forth on Attachment A from time to time opposite the caption
"Collateral Insurance Amount" against all loss or damage under an "all risk"
Policy with companies mutually acceptable to IBM Credit and Customer, with a
lender's loss payable endorsement or mortgagee clause in form and substance
reasonably satisfactory to IBM Credit designating that any loss payable
thereunder with respect to such Collateral shall be payable to IBM Credit. Upon
receipt of proceeds by IBM Credit the same shall be applied on account of the
Customer's Outstanding Product Advances first, then to the Outstanding A/R
Advances. Customer agrees to instruct each insurer to give IBM Credit, by
endorsement upon the Policy issued by it or by independent instruments furnished
to IBM Credit at least ten (10) days written notice before any Policy shall be
altered or cancelled and that no act or default of Customer or any other person
shall affect the right of IBM Credit to recover under the Policies. Customer
hereby agrees to direct all insurers under the Policies to pay all proceeds with
respect to the Collateral directly to IBM Credit.

If Customer fails to pay any cost, charges or premiums, or if Customer fails
to insure the Collateral, IBM Credit may pay such costs, charges or premiums.
Any amounts paid by IBM Credit hereunder shall be considered an additional debt
owed by Customer to IBM Credit and are due and payable immediately upon receipt
of an invoice by IBM Credit.

or assessed against Customer or any of the Collateral before any penalty or
interest accrues thereon unless such taxes are being contested, in good faith,
by appropriate proceedings promptly instituted and diligently conducted and an
adequate reserve or other appropriate provisions have been made therefore as
required in order to be in conformity with GAAP and an adverse determination in
such proceedings could not reasonably be expected to have a Material Adverse

Law applicable to the Collateral or any part thereof, or to the operation of its
business.

properties (business and otherwise) in good condition and

                                 Page 33 of 46

to Customer or sells such goods in the ordinary course of business, whichever
occurs earlier;

   (E)  stamp or otherwise mark chattel paper and instruments now owned or
hereafter acquired by it in conspicuous type to show that the same are subject

Credit, make, execute and deliver any assignments and other instruments
sufficient for the purpose of assigning any such award or payment to IBM Credit,
free of any encumbrances of any kind whatsoever;

   (H)  consistent with reasonable commercial practice, observe and perform all

records (including the copying of any computer records), and any receptacles or
cabinets containing same, relating to the Accounts, or IBM Credit may use (at
the expense of the Customer) such of the supplies or space of the Customer at
Customer's place of business or otherwise, as may be necessary to properly
administer and control the Accounts or the handling of collections and
realizations thereon; (ii) bring suit, in the name of the Customer or IBM Credit
and generally shall have all other rights respecting said Accounts, including
without limitation the right to accelerate or extend the time of payment,
settle, compromise, release in whole or in part any amounts owing on any
Accounts and issue credit in the name of the Customer or IBM Credit;

(iii) sell, assign and deliver the Accounts and any returned, reclaimed or
repossessed merchandise, with or without advertisement, at public or private
sale, for cash, on credit or otherwise, at IBM Credit's sole option and
discretion, and IBM Credit may bid or become a purchaser at any such sale; and
(iv) foreclose the security interests created pursuant to this Agreement by any
available judicial procedure, or to take possession of any or all of the
Collateral without judicial process and to enter any premises where any
Collateral may be located for the purpose of taking possession of or removing
the same.

   (B) Upon the occurrence and during the continuance of any Event of Default
which has not been waived in writing by IBM Credit, IBM Credit shall have the
right to sell, lease, or otherwise dispose of all or any part of the Collateral,
whether in its then condition or after further preparation or processing, in the
name of Customer or IBM Credit, or in the name of such other party as IBM Credit
may designate, either at public or private sale or at any broker's board, in
lots or in bulk, for cash or for credit, with or without warranties or
representations, and upon such other terms and conditions as IBM Credit in its
sole discretion may deem advisable, and IBM Credit shall have the right to
purchase at any such sale. If IBM Credit, in its sole discretion may deem
advisable, and IBM Credit shall have the right to purchase at any such sale. If
IBM Credit, in its sole discretion determines that any of the Collateral
requires rebuilding, repairing, maintenance or preparation, IBM Credit shall
have the right, at its option, to do such of the aforesaid as it deems necessary
for the purpose of putting such Collateral in such salable form as IBM Credit
shall deem appropriate. The Customer hereby agrees that any disposition by IBM
Credit of any Collateral pursuant to and in accordance with the terms of a
repurchase agreement between IBM Credit and the manufacturer or any supplier
(including any Authorized Supplier) of such Collateral

                                 Page 40 of 46
<PAGE>
 
constitutes a commercially reasonable sale.  The Customer agrees, at the request
of IBM Credit, to assemble the Collateral and to make it available to IBM Credit
at places which IBM Credit shall select, whether at the premises of the Customer
or elsewhere, and to make available to IBM Credit the premises and facilities of
the Customer for the purpose of IBM Credit's taking possession of, removing or
putting such Collateral in salable form.  If notice of intended disposition of
any Collateral is required by law, it is agreed that ten (10) Business Days
notice shall constitute reasonable notification.

  (C)  Unless expressly prohibited by the licensor thereof, if any, IBM
Credit is hereby granted, upon the occurrence and during the continuance of any
Event of Default which has not been waived in writing by IBM Credit, an
irrevocable, non-exclusive license to use, assign, license or sublicense all
computer software programs, data bases, processes and materials used by the
Customer in its businesses or in connection with any of the Collateral.

  (D)  The net cash proceeds resulting from IBM Credit's exercise of any
of the foregoing rights (after deducting all charges, costs and expenses,
including reasonable attorneys' fees) shall be applied by IBM Credit to the
payment of Customer's Obligations, whether due or to become due, in such order
as IBM Credit may in it sole discretion elect.  Customer shall remain liable to
IBM Credit for any deficiencies, and IBM Credit in turn agrees to remit to
Customer or its successors or assigns, any surplus resulting therefrom.

  (E)  The enumeration of the foregoing rights is not intended to be
exhaustive and the exercise of any right shall not preclude the exercise of any
other rights, all of which shall be cumulative.

9.4.  Waiver.  If IBM Credit seeks to take possession of any of the Collateral
by any court process Customer hereby irrevocably waives to the extent permitted
by applicable law any bonds, surety and security relating thereto required by
any statute, court rule or otherwise as an incident to such possession and any
demand for possession of the Collateral prior to the commencement of any suit or
action to recover possession thereof.  In addition, Customer waives to the
extent permitted by applicable law all rights of set-off it may have against IBM
Credit.  Customer further waives to the extent permitted by applicable law
presentment, demand and protest, and notices of non-payment, non-performance,
any right of contribution, dishonor, and any other demands, and notices required
by law.

             Section 10. MISCELLANEOUS

10.1.  Term; Termination.  (A) This Agreement shall remain in force until the
earlier of (i) the Termination Date, (ii) the date specified in a written notice
by the Customer that they intend to terminate this Agreement which date shall be
no less than ninety (90) days following the receipt by IBM Credit of such
written notice, and (iii) termination by IBM Credit after the occurrence and
during the continuance of any Event of Default. Upon the date that this

and payable in their entirety, even if they are not yet due under their terms.

                                 Page 41 of 46
<PAGE>
 
  (B)  Until the indefeasible payment in full of all of Customer's
Obligations, no termination of this Agreement or any of the Other Documents
shall in any way affect or impair (i) Customer's Obligations to IBM Credit
including, without limitation, any transaction or event occurring prior to and
after such termination, or (ii) IBM Credit's rights hereunder, including,
without limitation IBM Credit's security interest in the Collateral.  On and
after a Termination Date, IBM Credit may, but shall not be obligated to, upon
request of Customer, continue to provide Advances hereunder.

10.2.  Indemnification.  The Customer hereby agrees to indemnify and hold
harmless IBM Credit and each of its officers, directors, agents and assigns
(collectively, the "Indemnified Persons") against all losses, claims, damages,
liabilities or other expenses (including reasonable attorneys' fees and court
costs now or hereinafter arising from the enforcement of this Agreement, the
"Losses") to which any of them may become subject insofar as such Losses arise
out of or are based upon any event, circumstance or condition (a) occurring or
existing on or before the date of this Agreement relating to any financing
arrangements IBM Credit may from time to time have with (i) Customer, (ii) any
Person that shall be acquired by Customer or (iii) any Person that Customer may
acquire all or substantially all of the assets of, or (b) directly or
indirectly, relating to the execution, delivery or performance of this Agreement
or the consummation of the transactions contemplated hereby or thereby or to any
of the Collateral or to any act or omission of the Customer in connection
therewith. Notwithstanding the foregoing, the Customer shall not be obligated to
indemnify IBM Credit for any Losses incurred by IBM Credit which are a result of
IBM Credit's gross negligence or willful misconduct. The indemnity provided
herein shall survive the termination of this Agreement.

10.3.  Additional Obligations.  IBM Credit, without waiving or releasing any
Obligation or Default of the Customer, may perform any Obligations of the
Customer that the Customer shall fail or refuse to perform and IBM Credit may,
at any time or times hereafter, but shall be under no obligation so to do, pay,
acquire or accept any assignment of any security interest, lien, encumbrance or
claim against the Collateral asserted by any person.  All sums paid by IBM
Credit in performing in satisfaction or on account of the foregoing and any
expenses, including reasonable attorney's fees, court costs, and other charges
relating thereto, shall be a part of the Obligations, payable on demand and
secured by the Collateral.

10.4.  LIMITATION OF LIABILITY.  NEITHER IBM CREDIT NOR ANY OTHER INDEMNIFIED
PERSON SHALL HAVE ANY LIABILITY WITH RESPECT TO ANY SPECIAL, INDIRECT OR
CONSEQUENTIAL DAMAGES SUFFERED BY CUSTOMER IN CONNECTION WITH THIS AGREEMENT,
ANY OTHER AGREEMENT OR ANY CLAIMS IN ANY MANNER RELATED THERETO.  NOR SHALL IBM
CREDIT OR ANY OTHER INDEMNIFIED PERSON HAVE ANY LIABILITY TO CUSTOMER OR ANY
OTHER PERSON FOR ANY ACTION TAKEN OR OMITTED TO BE TAKEN BY IT OR THEM
HEREUNDER, EXCEPT FOR ITS OR THEIR OWN GROSS NEGLIGENCE OR WILLFUL MISCONDUCT.

10.5  Alteration Waiver.  This Agreement and the Other Documents may not be
altered or amended except by an agreement in writing signed by

                                 Page 42 of 46
<PAGE>
 
    
the Customer and by IBM Credit. No delay or omission of IBM Credit to exercise
any right or remedy hereunder, whether before or after the occurrence of any
Event of Default, shall impair any such right or remedy or shall operate as a
waiver thereof or as a waiver of any such Event of Default. In the event that
IBM Credit at any time or from time to time dispenses with any one or more of
the requirements specified in this Agreement or any of the Other Documents, such
dispensation may be revoked by IBM Credit at any time and shall not be deemed to
constitute a waiver of any such requirement subsequent thereto. IBM Credit's
failure at any time or times to require strict compliance and performance by the
Customer of any undertakings, agreements, covenants, warranties and
representations of this Agreement or any Other Document shall not waive, affect
or diminish any right of IBM Credit thereafter to demand strict compliance and
performance thereof. Any waiver by IBM Credit of any Default by the Customer
under this Agreement or any of the Other Documents shall not waive or affect any
other Default by the Customer under this Agreement or any of the Other
Documents, whether such Default is prior or subsequent to such other Default and
whether of the same or a different type. None of the undertakings, agreements,
warranties, covenants, and representations of the Customer contained in this
Agreement or the Other Documents and no Default by the Customer shall be deemed
waived by IBM Credit unless such waiver is in writing signed by an authorized
representative of IBM Credit.     

10.6.  Severability.  If any provision of this Agreement or the Other Documents
or the application thereof to any Person or circumstance is held invalid or
unenforceable, the remainder of this Agreement and the Other Documents and the
application of such provision to other Persons or circumstances will not be
affected thereby, the provisions of this Agreement and the Other Documents being
severable in any such instance.

10.7.  One Loan.  All Advances heretofore, now or at any time or times hereafter
made by IBM Credit to the Customer under this Agreement or the Other Documents
shall constitute one loan secured by IBM Credit's security interests in the
Collateral and by all other security interests, liens and encumbrances
heretofore, now or from time to time hereafter granted by the Customer to IBM
Credit or any assignor of IBM Credit.

10.8.  Additional Collateral.  All monies, reserves and proceeds received or
collected by IBM Credit with respect to Accounts and other property of the
Customer in possession of IBM Credit at any time or times hereafter are hereby
pledged by Customer to IBM Credit as security for the payment of Customer's
Obligations and shall be applied promptly by IBM Credit on account of the
Customer's Obligations; provided, however, IBM Credit may release to the
Customer such portions of such monies, reserves and proceeds as IBM Credit may
from time to time determine, in its sole discretion.

10.9.  No Merger or Novations.  A) Notwithstanding anything contained in any
document to the contrary, it is understood and agreed by the Customer and IBM
Credit that the claims of IBM Credit arising hereunder and existing as of the
date hereof constitute continuing claims arising out of the Obligations of
Customer under the Financing Agreement and any Other Document. Customer
acknowledges and agrees that such Obligations

                                 Page 43 of 46
<PAGE>
 
outstanding as of the date hereof have not been satisfied or discharged and
that this Agreement is not intended to effect a novation of the Customer's
Obligations under the Financing Agreement or any Other Document.

  (B)  Neither the obtaining of any judgment nor the exercise of any power
of seizure or sale shall operate to extinguish the Obligations of the Customer
to IBM Credit secured by this Agreement and shall not operate as a merger of any
covenant in this Agreement, and the acceptance of any payment or alternate
security shall not constitute or create a novation and the obtaining of a
judgment or judgments under a covenant herein contained shall not operate as a
merger of that covenant or affect IBM Credit's rights under this Agreement.

10.10. Paragraph Titles.  The Section titles used in this Agreement and the
Other Documents are for convenience only and do not define or limit the contents
of any Section.

10.11. Binding Effect; Assignment.  This Agreement and the Other Documents shall
be binding upon and inure to the benefit of IBM Credit and the Customer and
their respective successors and assigns; provided, that the Customer shall have
no right to assign this Agreement or any of the Other Documents without the
prior written consent of IBM Credit.

10.12. Notices.  Except as otherwise expressly provided in this Agreement, any
notice required or desired to be served, given or delivered hereunder shall be

     Re:  Pulsar Data Systems, Inc.
          Inventory and Working Capital Financing Agreement

Ladies and Gentlemen:

     We have acted as counsel for Pulsar Data Systems, Incorporated, a Delaware
corporation (the "Borrower") in connection with the exception and delivery of
that certain Inventory and Working Capital Financing Agreement, dated as of
October 24, 1997 (the "Financing Agreement"), by and among the Borrower and IBM
Credit Corporation ("IBM Credit"), and the other agreements, instruments, and
documents executed and delivered by the Borrower in connection with the
Financing Agreement. Unless otherwise defined herein, capitalized terms used
herein shall have the meanings ascribed to such terms in the Financing
Agreement.

     In this connection, we have examined the following document:

     (i)   The Certificate of Incorporation of the By-laws of the Borrower, each
as amended to date;

     (i)   The records of the proceedings taken by the Board of Directors of the
Borrower in connection with the execution, delivery, and performance of the
Financing Documents to which they are a party (as defined below);


                            Corporate Headquarters
                         4500 Forbes Blvd., Suite 400

     (iii)  The Financing Agreement;

     (iv)   The contingent Blocked Account Amendment;

     (v)    Acknowledgment copies of the UCC-1 Financing Statements listed on
            Exhibit A hereto (the "Financing Statements") executed by the
            Borrower naming it as Debtor and IBM Credit as Secured Party and
            filed in the offices set forth on Exhibit A;

            The documents referred to in clauses (iii) through (vi) above are
hereinafter referred to as the Financing Documents.

            In our examination, we have assumed the genuineness of all
signatures, the legal capacity of natural persons, the authenticity of all
documents submitted to us as originals, the conformity to original copies, and
the authenticity of the originals of such latter documents, and, regarding
documents executed by parties other than the Borrower, that those parties had
the power and the capacity to enter into, execute, delivery and perform all
obligations under such documents, the due authorization of all requisite action
with respect to such documents, and the validity and binding effect of such
documents upon such other parties.

            As to any facts material to this opinion, we have relied upon the
representations and warranties of the Borrower contained in each of the
Financing Documents, and in certificates delivered by the Borrower pursuant to
each of the Financing Documents, statements, and representations of officers and
other representatives of the Borrower, and, as to the matters addressed therein,
certificates or correspondence from public officials. For purposes of the
opinion set forth in Paragraph 4, the term "Material Contracts" means the
agreements and instruments to which the Borrower is subject which have been
identified to us by officers of the Borrower and set forth on Exhibit B hereto
as the agreements and instruments which are material to the business or
financial condition of the Borrower: and the term "Material Orders" means those
orders and decrees to which the Borrower is subject which have     

                                 Page 16 of 21

been identified to us by officers of the Borrower and set forth in Exhibit C
hereto as the orders and decrees, agreements, and instruments which are material
to the business or financial condition of the Borrower.

     As used herein, the term "UCC" refers to the Uniform commercial Code as in
effect in the State of New York.

     We are members of the bar in the State of Maryland and Pennsylvania and
express no opinion as to the laws of any other jurisdiction except the General
Corporation Law of the State of Maryland and the federal laws of the United
States of America.

     Based on the foregoing, and subject to the assumptions and qualifications
set forth herein, we are of the opinion that:

     1.   Borrower by July 10, 1997 will be a corporation duly organized,
validity existing and in good standing under the laws of the jurisdiction of its
incorporation and is duly qualified and authorized to do business and in good
standing as a foreign corporation in each jurisdiction where, to our knowledge,
it presently is engaged in business and is required to be qualified.

     2.   Borrower has all or will have all the requisite corporate power and
authority (a) to own, lease, and operate its properties and assets and to carry
on its business as now being conducted; and (b) to execute, delivery, and
performance of the Financing Documents to which it is a party.

     3.   All corporate action on the part of the Borrower requisite for the
execution, delivery, and performance of the Financing Documents to which it is
party will be duly taken.

     4.   The execution, delivery, and performance by the Borrower of the
Financing Documents to which it is a party will not (a) violate, be in conflict
with, result in the breach of, or constitute (with due notice or

lapse of time, or both) a default under (I) the Certificate of Incorporation or
By-laws of Borrower or any resolution of its Board of Directors or any committee
thereof, (ii) any Material Contract, or (iii) any federal or state law
(including, without limitation, environmental or occupational health, and safety
law), regulation, rule, Material Order, or legal requirement of any federal,
state, or public authority or agency applicable to Borrower; or (b) result in
the creation or imposition of a lien of any nature whatsoever upon any of the
Borrower's property or assets other than as represented by the Financing
Documents.

     5.   Borrower has obtained any and all consents, approvals, or other
authorizations required to be obtained pursuant to its Certificate of
Incorporation and By-laws in connection with the execution, delivery, and
performance of the Financing Documents. No consent, approval, or authorization
of or by any court, administrative agency, other governmental authority, or any
other Person is required in connection with the execution, delivery, and
performance by the Borrower of the Financing Documents that has not already been
obtained.

     6.   To our knowledge, there are no actions, proceedings, or investigations
pending or threatened against the Borrower which question the validity of the
Financing Documents to which it is a party or relating the transactions
contemplated thereby, except for those investigations which IBM Credit has
knowledge of by full disclosure of the Borrower.

     7.   Each of the Financing Documents has been duly executed and delivered
by duly authorized officer of the Borrower and constitutes the legal, valid,
binding obligation of the Borrower, enforceable against the Borrower in
accordance with its terms, except that, in each case, (I) enforcement may be
subject to and limited by applicable bankruptcy, insolvency, reorganization,
moratorium, or other laws now or hereafter in effect relating to creditors'
rights generally, (ii) the remedy of specific performance and injunctive and
other forms of equitable relief may be subject to equitable defenses and to the
discretion of the court before which any proceeding therefor may be brought. and
(iii) certain of the     

                                 Page 18 of 21

remedial provisions including waivers with respect to the exercise of remedies
against the Collateral contained in the Financing Documents may be unenforceable
in whole or in part, but the inclusion of such provisions does not affect the
validity of the Financing Documents, each taken as a whole and, the Financing
Documents, each taken as a whole, contain adequate remedial provisions for the
practical realization of the security purported to be afforded thereby.

     8.   The Financing Agreement is effective to create in favor of IBM Credit
a valid security interest within the meaning of the UCC in the Collateral as
security for the obligations purported to be secured thereby; and (ii) the
Financing Statements are in appropriate form and have been duly filed resulting
in a perfected security interest (as such term is defined in Section 9-303 of
the UCC) of IBM Credit in the Collateral in which security interests to which
Article 9 of the UCC applies.

     9.   Borrower is not an "investment company" or a company "controlled" by
an "investment company," within the meaning of the Investment Company Act of
1940, as amended.

     This opinion is rendered solely to and for the benefit of IBM Credit in
connection with the execution and delivery of the Financing Documents and may
not be relied upon by any other person, firm, or corporation without our prior
written consent, except that it may be furnished to any prospective purchaser of
a participation in the rights of IBM Credit and may be furnished to an relied
upon by any Person which hereafter acquires such a participation.

     This opinion is limited to laws as currently in effect on the date hereto
and the facts as they currently exist. We assume no obligation to revise,
supplement or otherwise update this opinion.

                              Very truly yours,

                              /s/ Christopher R. Locke

<PAGE>

anything to be brought into or kept there which, in the sole judgment of Lessor,
shall in any way impair or tend to impair the high quality character, reputation
or appearance of the Building or the Facility, or which may or tend to impair or
interfere with any services performed by Lessor for Lessee or for others.     

     3.   Term.
          -----
    
     a.   The term of this Agreement shall be for a period of 6 months,
commencing 9:00 a.m. on the 1st day of February 1999, and ending 5:00 p.m. on
the 31st day of July, 1999, unless renewed as provided in paragraph "3(b)"
herein.

     b.   Upon the ending term date set forth herein or any extension thereof,
the Agreement shall be extended for the same period of time as the initial term
and upon the same terms and conditions as herein contained except for the amount
of base rental charges, which shall each be increased by at least ten percent
(10%), unless either party notifies the other in writing by certified or
registered mail, return receipt requested, or delivered by hand that the
Agreement shall not be extended within the period hereinafter specified or
automatically renewed. If Lessee has less than three offices, such notice shall
be given at least 60 days prior to the expiration date of this Agreement. If
Lessee has three or more offices, such notice shall be given at least 90 days
prior to the expiration date of this Agreement.     

     c.   In the event the entire Premises or the Facility are damaged,
destroyed or taken by eminent domain or acquired by private purchase in lieu of
eminent domain so as to render the Premises fully untenantable and unrestorable
in Lessor's sole judgment, then within 90 days thereafter by written notice to
the other party, either party shall be able to terminate this Agreement, which
will terminate as of the date thereof.

     4.   Rent.
          -----
    
     a.   For and during the term of this Agreement, Lessee shall pay Lessor as
rent for the Premises a total rental of $ 33,738, payable in 6 equal monthly
installments of $ 5623 (unless otherwise indicated on Rebate Rider attached),
each payable in advance of the first day of each calendar month after the
commencement of the term, or a daily prorated amount for any partial calendar
month during the term. If any payment of rent or other charges due under this
Agreement is not received within five (5) calendar days after its due date, the
Lessee will also pay, as additional rent, a late payment charge which shall be
an amount equal to 10% of any amount owed to Lessor or $50 whichever is greater.
     

     b.   It is additionally specifically covenanted and agreed that the
financial terms of this Agreement are strictly confidential and Lessee agrees
not to knowingly or willfully divulge this information to or any other Lessee or
potential Lessee of Lessor. Any such disclosure by the Lessee

                                       2
<PAGE>
 
of the financial terms of this Agreement as set forth herein above, shall
constitute a material breach of this Lease.

     c.   The first such payment of rental as well as the payment of the Deposit
as set forth in below shall be billed by Lessor simultaneously with execution of
this Agreement. Should the Lessee fail to make such payment prior to the
commencement of the term of this Agreement, then, at Lessor's sole option, the
Agreement shall be null and void and of no further effect.
    
     d.   The rental payable during the term of this Agreement shall be
increased on the first day of the month following notification of any rental
increase (however designated) which the Lessor might receive form the Lessor's
over-landlord ("Building").  The term "direct expenses" as used herein shall
refer to the same items and costs as are used by the Building in its
determination of expenses and costs passed on to Lessor.  Lessor shall
immediately notify Lessee in writing of any such increase, and shall bill Lessee
for its pro rata share thereof, which bill Lessee shall pay promptly upon such
notification for each and every month thereafter for the balance of the term.

     e.   Rent charges are based on the value of the rental Premises and
services to be used by no more than five (5) person(s) only. If more than said
number of person(s) habitually use the Premises or services, the Fixed Monthly
Rental Charges will be increased by a factor of $100 (not included furnishings)
for each additional person who habitually uses the Premises.

     f.   If a Lessee check is returned for any reason, Lessee will pay an
additional charge of $100.00 per returned check and, for the purpose of
considering default and/or late charges, it will be as if the payment
represented by the returned check had never been made.     

     5.   Security Deposit.
          -----------------
    
     a.   Lessee has deposited with Lessor $5623; $3300 already on hand; $2323
due on February 1, 1999 or the equivalent of one month's rent, in good or
certified funds with a domestic bank, as a non-interest bearing security
deposit. Lessor may use the security deposit to cure any default of Lessee under
this Agreement, restore the Premises including any and all furniture, fixtures
and equipment provided by Lessor and vendors at the Premises to their original
condition and configuration, reasonable wear and tear excepted, to pay for
repairs to any damage to the Premises, Executive Suite or Building, caused by
Lessee or Lessee's guests, to pay any rent or other charges which Lessee owes
Lessor at or prior to the expiration of this Agreement, and to reimburse Lessor
for costs or expenses arising from any other obligation of Lessee which Lessee
has failed to perform. If Lessor transfers control or ownership of the Premises
and Lessor transfers the security deposit to such purchaser, Lessee will look
solely to the new Lessor for the return of the security deposit, and the Lessor
named in this Agreement shall be released from all liability for the return of
the security deposit.     

     b.   The security deposit (less any sums used by Lessor in accordance with
the terms and conditions of this Agreement) will be returned within sixty (60)
days after the termination of any services rendered or expiration of the term
hereof. The security deposit shall not under any 

                                       3
<PAGE>
 
circumstance be applied in lieu of be the final payment(s) of Fixed Monthly
Rental charges or service charges under this Agreement.

     c.   In the event that, by reason of the Lessee's default in its
obligations pursuant to this Agreement or otherwise, including but not limited
to the payment of the Fixed Monthly Rental Charge, any amounts due by reason of
the Lessee's use of additional services hereto and/or by reason of the Lessee's
use of telephone services as supplied pursuant to this Agreement, Lessor shall
be entitled to apply any of the security deposited pursuant to this Agreement to
any outstanding sums due or owing to the Lessor, and Lessor shall have the right
to charge the Lessee, as additional rent, such sums as are necessary to
replenish any and all amounts applied so as to cause the security to be returned
to its entire amount. The failure to pay such amounts as are necessary to
replenish the security shall be considered a breach of this Agreement and shall
entitle the Lessor to exercise any of its rights pursuant to this Agreement or
otherwise.

     6.   Delivery of Possession.
          -----------------------
    
     If, for any reason whatsoever, Lessor cannot deliver possession of the
Premises to Lessee at the commencement of the term, this Agreement shall not be
void nor voidable nor shall Lessor be liable to Lessee for any loss or damage
resulting therefrom; but there shall be an abatement of rent for the period
between the stated term commencement and the time when Lessor does deliver
possession of the Premises.     

     7.   Services.
          ---------
    
     a.   So long as Lessee is not in default hereunder, Lessor shall make
available certain amenities to Lessee as more particularly described in Exhibit
"A". Such services shall be offered to Lessee, in conjunction with such services
being offered by Lessor to its other lessees, without charge for the reasonable
use of the same.     

     b.   In addition, provided Lessee is not in default hereunder and provided
the cost thereof does not exceed the Security Deposit, Lessor shall make
available to Lessee certain other services the cost of which shall be billed to
the Lessee as additional rent and the payment of which shall be subject to the
same terms and conditions as those governing the payment of the Fixed Monthly
Rental Charge herein regardless of when such charges are billed to the Lessee.
    
     c.   There will be a Client Service Charge of $100/month per office.     

     8.   Telephone Services.
          -------------------
    
     a.   Provided Lessee is not in default of any of the terms, covenants,
conditions or provisions of this Agreement, Lessor will make available to
Lessee, a telecommunications package which will consist of some combination of
telephone equipment, numbers, lines, conference calling, voice mail, local, long
distance and international service, and directory listing. All components of the
telecommunications package including any telephone numbers used by Lessee will
remain

<PAGE>
 
    
at all times the property of Lessor and Lessee will acquire no rights in the
components beyond the term specified by Lessor.

damages.     

     d.   Lessor shall use reasonable efforts to provide Telephone Services to
Lessee in a first-class, professional manner. Telephone service charges shall be
as per Lessor's then scheduled rates for the same, or as the same may be amended
by Lessor from time to time.

     e.   In the event that any toll fraud is traceable to telecommunications
services employed by Lessee, such toll fraud shall be deemed to be a material
default in the Lessee's obligations hereunder. Lessee further hereby agrees to
indemnify, hold harmless and to reimburse Lessor for all charges associated with
any such toll fraud including, but not limited to, unauthorized use of calling
cards or telephone lines.
    
     f.   It is expressly acknowledged and agreed that Lessor shall be the sole
and exclusive provider of telecommunication services to Lessee.  Lessee hereby
agrees and covenants that it will not use any other telephone service or
telephone carrier to provide it service in the Premises. In the event that
Lessee uses or acquires any other telephone service at the Premises, such use
and/or installation shall constitute a material default in the Lessee's
obligations hereunder.     

     9.   Furniture and Fixtures.
          -----------------------

     At its own cost and expense, Lessor shall furnish and install furniture,

additional items needing work or repair by Landlord. Tenant acknowledges that

<PAGE>

(b)  DETERMINATION OF TENANT'S MONTHLY OPERATING EXPENSE CHARGE. Tenant's
Monthly Operating Expense Charge shall be determined as provided in Subparagraph
1(i) of this Lease. If Tenant's Monthly Operating Expense Charge is scheduled
for each year of the Lease Term as shown on Exhibit "B", then Subparagraphs (c)
and (d) below will not apply.
    
(c)  ESTIMATE STATEMENT. Prior to the Commencement Date and on or about March
1st of each subsequent calendar year during the Term of this Lease, Landlord
will endeavor to deliver to Tenant a statement ("Estimate Statement") wherein
Landlord will estimate both the Operating Expenses and Tenant's Monthly
Operating Expense Charge for the then current calendar year. Tenant agrees to
pay Landlord, as additional rent, Tenant's estimated Monthly Operating Expense
Charge each month thereafter, beginning with the next installment of rent due,
until such time as Landlord issues a revised Estimate Statement or the Estimate
Statement for the succeeding calendar year; except that, concurrently with the
regular monthly rent payment next due following the receipt of each such
Estimate Statement, Tenant agrees to pay Landlord an amount equal to one monthly
installment of Tenant's estimated Monthly Operating Expense Charge (less any
applicable Operating Expenses already paid) multiplied by the number of months
from January, in the current calendar year, to the month of such rent payment
next due, all months inclusive. If at any time during the Term of this Lease,
but not more often than quarterly, Landlord reasonably determines that
Tenant's's share of Operating Expenses for the current calendar year will be
greater than the amount set forth in the then current Estimate Statement,
Landlord may issue a revised Estimate Statement and Tenant agrees to pay
Landlord, within ten (10) days of receipt of the revised Estimate Statement, the
difference between the amount owed by Tenant under such revised Estimate
Statement and the amount owed by Tenant under the original Estimate Statement
for the portion of the then current calendar year which has expired. Thereafter
Tenant agrees to pay Tenant's Monthly Operating Expense Charge based on such
revised Estimate Statement until Tenant receives the next calendar year's
Estimate Statement or a new revised Estimate Statement for the current calendar
year.    
    
(d)  ACTUAL STATEMENT. By March 1st of each calendar year during the Term of
this Lease, Landlord will also endeavor to deliver to Tenant a statement
("Actual Statement") which states Tenant's Share of the actual Operating
Expenses for the preceding calendar year. If the    

                                       5
<PAGE>
 
    
Actual Statement reveals that Tenant's Share of the actual Operating Expenses is
more than the total Additional Rent paid by Tenant for Operating Expenses on
account of the preceding calendar year, Tenant agrees to pay Landlord the
difference in a lump sum within ten (10) days of receipt of the Actual
Statement. If the Actual Statement reveals that Tenant's Share of the actual
Operating Expenses is less than the Additional Rent paid by Tenant for Operating
Expenses on account of the preceding calendar year, Landlord will credit any
overpayment toward the next monthly installment(s) of Tenant's Share of the
Operating Expenses due under this Lease.

(e)  MISCELLANEOUS. Any delay or failure by Landlord in delivering any Estimate
Statement or Actual Statement pursuant to this Paragraph 6 will not constitute a
waiver of its right to require an increase in rent nor will it relieve Tenant of
its obligations pursuant to this Paragraph 6, except that Tenant will not be
obligated to make any payments based on such Estimate Statement or Actual
Statement unless ten (10) days after receipt of such Estimate Statement or
Actual Statement. If Tenant does not object to any Estimate Statement or Actual
Statement within thirty (30) days after Tenant receives any such statement, such
statement will be deemed final and binding on Tenant. Even though the Term has
expired and Tenant has vacated the Premises, when the final determination is
made of Tenant's Share of the actual Operating Expenses for the year in which
this Lease terminates, Tenant agrees to promptly pay any increase due over the
estimated expenses paid and, conversely, any overpayment made in the event said
expenses decrease shall promptly be rebated by Landlord to Tenant. Such
obligation will be a continuing one which will survive the expiration or
termination of this Lease. Prior to the expiration or sooner termination of the
Lease Term and Landlord's acceptance of Tenant's surrender of the Premises,
Landlord will have the right to estimate the actual Operating Expenses for the
then current Lease Year and to collect from Tenant prior to Tenant's surrender
of the Premises, Tenant's Share of any excess of such actual Operating Expenses
over the estimated Operating Expenses paid by Tenant in such Lease Year.

7.   SECURITY DEPOSIT AND CLEANING FEE. Upon Tenant's execution of this Lease,
Tenant will deposit with Landlord the Security Deposit designated in
Subparagraph 1(j). The Security Deposit will be held by Landlord as security for
the full and faithful performance by Tenant of all of the terms, covenants, and
conditions of this Lease to be kept and performed by Tenant during the Term
hereof. The Security Deposit is not, and may not be construed by Tenant to
constitute, rent for the last month or any portion thereof. If Tenant defaults
with respect to any provisions of this Lease including, but not limited to, the
provisions relating to the payment of rent or additional rent, Landlord may (but
will not be required to) use, apply or retain all or any part of the Security
Deposit for the payment of any rent or any other sum in default, or for the
payment of any other amount which Landlord may spend by reason of Tenant's
default or to compensate Landlord for any loss or damage which Landlord may
suffer by reason of Tenant's default. If any portion to the Security Deposit is
so used or applied, Tenant agrees, within ten (10) days after Landlord's written
demand therefor, to deposit cash with Landlord in an amount sufficient to
restore the Security Deposit to its original amount and Tenant's failure to do
so shall constitute a default under this Lease. Landlord is not required to keep
Tenant's Security Deposit separate from its general funds, and Tenant is 
not     

                                       6
<PAGE>
 
    
entitled to interest on such Security Deposit. If Tenant is not in default at
the expiration or termination of this Lease, Landlord will return the Security
Deposit to Tenant, less the non-refundable Cleaning Fee portion designated in
Subparagraph 1(k). Landlord's obligations with respect to the Security Deposit
are those of a debtor and not of a trustee.

cause Tenant to immediately take all steps Landlord deems necessary or
appropriate to remediate such release and prevent any similar future release to
the satisfaction of Landlord and Landlord's mortgagee(s). At all times during
the Term of this Lease, Landlord will have the right, but not the obligation, to

11.  SURRENDER; HOLDING OVER.
    
(a)  SURRENDER.  The voluntary or other surrender of this Lease by Tenant, or a
mutual cancellation thereof, shall not constitute a merger, and shall, at the
option of Landlord, operate as an assignment to Landlord of any or all subleases

a state of good order, repair and condition, ordinary wear and tear and casually
damage excepted, with all of Tenant's personal property and alterations removed

surrender of the Premises.     
    
(b)  HOLDING OVER. If Tenant holds over after the expiration or earlier
termination of the Term, Landlord may, at its option, treat Tenant as a tenant

such holdover. Acceptance by Landlord of rent alter such expiration or earlier
termination will not result in a renewal of this Lease. If Tenant fails to
surrender the Premises upon the expiration of this Lease in accordance with the
terms of this Paragraph 11 despite demand to do so by Landlord, Tenant agrees to
promptly indemnify, protect, defend and hold Landlord harmless from all claims,
damages, judgments, suits, causes of action, losses, liabilities, penalties,
fines, expenses and costs (including attorneys" fees and costs), including,
without limitation, costs and expenses incurred by Landlord in returning the
Premises to the condition in which Tenant was to surrender it and claims made by

property of Landlord and will remain upon and be surrendered with the Premises

Tenant to remove any or all alterations at the end of the Term of this Lease. If
Tenant fails to remove by the expiration or earlier termination of this Lease
all of its personal property, or any alterations identified by Landlord for
removal, Landlord may, at its option, treat such failure as a hold-over pursuant
to Subparagraph 11(b) above, and/or Landlord may (without liability to Tenant
for loss thereof) treat such personal property and/or alterations as abandoned
and, at Tenant's sole cost and expense and in addition to Landlord's other
rights and remedies under this Lease, at law or in equity: (a) remove and store
such items; and/or (b) upon ten (10) days" prior notice to Tenant, sell, discard
or otherwise dispose of all or any such items at private or public sale for such
price as Landlord may obtain or by other commercially reasonable means. Tenant

Landlord shall have no liability to Tenant with respect to any such abandoned
property. Landlord agrees to apply the proceeds of any sale of any such property
to any amounts due to Landlord under this Lease from Tenant (including
Landlord's attorneys" fees and other costs incurred in the removal, storage

plumbing and sewer systems, including those portions of such systems which are
outside the Premises, gutters and downspouts on the Building and the heating,

Tenant will not be entitled to any abatement of rent and Landlord will not have
any liability by reason of any injury to or interference with Tenant's business
arising from the making of any repairs, alterations or improvements in or to any
portion of the Building or the Premises or in or to fixtures, appurtenances and
equipment therein. Tenant waives the right to make repairs at Landlord's expense
under any law, statute, ordinance, rule, regulation, order or ruling (including,

contractors. If Tenant refuses or neglects to repair and maintain the Premises

liens to be filed against all or any part of the Project, the Building or the

                                       11
<PAGE>
 
    
of Tenant or Tenant's agents, employees, contractors, licensees or invitees. At
Landlord's request, Tenant agrees to provide Landlord with enforceable,
conditional and final lien releases (or other evidence reasonably requested by
Landlord to demonstrate protection from liens) from all persons furnishing labor

on any door of the Premises without Landlord's prior written consent and without
providing Landlord with a key to all such locks. Except in the case of the gross

not be unable to Tenant for any damages or losses resulting from any such entry.

services or utilities, Tenant shall not be entitled to any abatement or
reduction of      

                                       12
<PAGE>
 
    
rent (except as expressly provided in Subparagraphs 20(f) or 21(b) if such
failure results from a damage or taking described therein), no eviction of
Tenant will result from such failure and Tenant will not be relieved from the
performance of any covenant or agreement in this Lease because of such failure.
In the event of any failure, stoppage or interruption thereof, Landlord agrees
to diligently attempt to resume service promptly.     

18.  ASSUMPTION OF RISK AND INDEMNIFICATION.
    
     (a) ASSUMPTION OF RISK. Tenant, as a material part other consideration to
Landlord, agrees that neither Landlord nor any Landlord indemnified Parties (as
defined in Subparagraph 8(c) above) will be liable to Tenant for, and Tenant
expressly assumes the risk of and waives any and all claims it may have against
Landlord or any Landlord Indemnified Parties with respect to, (i) any and all
damage to property or injury to persons in, upon or about the Premises, the
Building or the Project resulting from the act or omission (except for the
grossly negligent or intentionally wrongful act or omission) of Landlord, (ii)
any such damage caused by other tenants or persons in or about the Building or
the Project, or caused by quasi-public work, (iii) any damage to property
entrusted to employees of the Building, (iv) any loss of or damage to property
by them or otherwise, or (v) any injury or damage to persons or property
resulting from any casualty, explosion, falling plaster or other masonry or
glass, steam, gas, electricity, water or rain which may leak  from any part of
the Building or any other portion of the Project or from the pipes, appliances
or plumbing works therein or from the root, street or subsurface or from any
other place, or resulting from dampness. Neither Landlord nor any Landlord
Indemnified Parties will be liable for consequential damages arising out of any
loss of the use of the Premises or any equipment or facilities therein by Tenant
or any Tenant Parties (as defined in Subparagraph 8(c) above) or for
interference with light. Tenant agrees to give prompt notice to Landlord in case
of fire or accidents in the Premises or the Building, or of detects therein or
in the fixtures or equipment.     
    
(b)  INDEMNIFICATION. Tenant will be liable for, and agrees, to the maximum
extent permissible under applicable law, to promptly indemnify, protect, defend
and hold harmless Landlord and all Landlord Indemnified Parties, from and
against, any and all claims, damages, judgments, suits, causes of action,
losses, liabilities, penalties, fines, expenses and costs, including attorneys"
fees and court costs (collectively, "Indemnified Claims"), arising or resulting
from (i) any act or omission of Tenant or any Tenant Parties; (ii) the use of
the Premises and Common Areas and conduct of Tenant's business by Tenant or any
Tenant Parties, or any other activity, work or thing done, permitted or suffered
by Tenant or any Tenant Parties, in or about the Premises, the Building or
elsewhere within the Project and/or (iii) any default by Tenant of any
obligations on Tenant's part to be performed under the terms of this Lease. In
case any action or proceeding is brought against Landlord or any Landlord
indemnified Parties by reason of any such indemnified Claims, Tenant, upon
notice from Landlord, agrees to promptly defend the same at Tenant's sole cost
and expense by counsel approved in writing by Landlord, which approval Landlord
will not unreasonably withhold.    

                                       13

(c)  SURVIVAL; NO RELEASE OF INSURERS. Tenant's indemnification obligations
under Subparagraph 18(b) will survive the expiration or earlier termination of
this Lease Tenant's covenants, agreements and indemnification obligation in
Subparagraphs 18(a) and 18(b) above, are not intended to and will not relieve
any insurance carrier of its obligations under policies required to be carried
by Tenant pursuant to the provisions of This Lease.

19.  INSURANCE.
    
(a)  TENANT'S INSURANCE. On or before the earlier to occur of (i) the
Commencement Date, or (ii) the date Tenant commences any work of any type in the
Premises pursuant to this Lease (which may be prior to the Commencement Date),
and continuing throughout the entire Term hereof and any other period of
occupancy, Tenant agrees to keep in full force and effect, at its sole cost and
expense, the insurance specified on Exhibit "F" attached hereto. Landlord
reserves the right to require any other form or forms of insurance as Tenant or
Landlord or any mortgagees of Landlord may reasonably require from time to time
in form, in amounts, and for insurance risks against which, a prudent tenant
would protect itself, but only to the extent coverage for such risks and amounts
are available in the insurance market at commercially acceptable rates Landlord
makes no representation that the limits of liability required to be carried by
Tenant under the terms of this Lease are adequate to protect Tenant's interests
and Tenant should obtain such additional insurance or increased liability limits
as Tenant deems appropriate.     
    
(b)  SUPPLEMENTAL TENANT INSURANCE REQUIREMENTS.  All policies must be in a form
reasonably satisfactory to Landlord and issued by an insurer admitted to do
business in the State. All policies must be issued by insurers with a
policyholder rating of "A" and a financial rating of "X" in the most recent
version of Best's Key Rating Guide. All policies must contain a requirement to
notify Landlord (and Landlord's property manager and any mortgagees or ground
lessors of Landlord who are named as additional insureds, if any) in writing not
less than thirty (30) days prior to any material change, reduction in coverage,
cancellation or other termination thereof. Tenant agrees to deliver to Landlord,
as soon as practicable after placing the required insurance, but in any event
within the time frame specified in Subparagraph 19(a) above, certificate(s) of
insurance and/or if required by Landlord, certified copies of each policy
evidencing the existence of such insurance and Tenant's compliance with the
provisions of this Paragraph 19. Tenant agrees to cause replacement policies or
certificates to be delivered to Landlord not less than thirty (30) days prior to
the expiration of any such policy or policies. If any such initial or
replacement policies or certificates are not furnished within the time(s)
specified herein, Landlord will have the right, but not the obligation, to
obtain such insurance as Landlord deems necessary to protect Landlord's
interests at Tenant's expense. Tenant's insurance under Subparagraphs 19(a)(iii)
and (iv) must name Landlord and Landlord's property manager (and at Landlord's
request, Landlord's mortgagees and ground lessors of which Tenant has been
informed in writing) as additional insureds and must also contain a provision
that the insurance afforded by such policy is primary insurance and any     

                                       14
<PAGE>
 
    
insurance carried by Landlord and Landlord's property manager or Landlord's
mortgagees or ground lessors, if any, will be excess over and non-contributing
with Tenant's insurance.     

(c)  WAIVER OF SUBROGATION. Tenant's property insurance shall contain a clause
whereby the insurer waives all rights of recovery by way of subrogation against
Landlord. Tenant shall also obtain and furnish evidence to Landlord of the
waiver by Tenant's worker's compensation insurance carrier of all rights of
recovery by way of subrogation against Landlord.

20.  DAMAGE OR DESTRUCTION.
    
(a)  PARTIAL DESTRUCTION. If the Premises or the Building are damaged by fire or
other casualty to an extent not exceeding twenty-five percent (25%) of the full
replacement cost thereof and Landlord's contractor reasonably estimates in a
writing delivered to Landlord and Tenant that the damage thereto may be
repaired, reconstructed or restored to substantially its condition immediately
prior to such damage within one hundred eighty (180) days from the date of such
casualty, and Landlord will receive insurance proceeds sufficient to cover the
costs of such repairs reconstruction and restoration (including proceeds from
Tenant and/or Tenants insurance which Tenant is required to deliver to Landlord
pursuant to Subparagraph 20(d) below to cover Tenant s obligation for the costs
of repair, reconstruction and restoration of any portion of the tenant
improvements and any alterations for which Tenant is responsible under this
Lease) then Landlord agrees to commence and proceed diligently with the work of
repair, reconstruction and restoration and this Lease will continue in full
force and effect.     
    
(b)  SUBSTANTIAL DESTRUCTION.  Any damage or destruction to the Premises or the
Building which Landlord is not obligated to repair pursuant to Subparagraph
20(a) above will be deemed a substantial destruction. In the event of a
substantial destruction, Landlord may elect to either: (i) repair reconstruct
and restore the portion of the Building or the Premises damaged by such casualty
in which case this Lease will continue in full force and effect, subject to
Tenant's termination right contained in Subparagraph 20(c) below; or (ii)
terminate this Lease effective as of the date of Tenant's receipt of Landlord s
election to so terminate.     
    
(c)  TERMINATION RIGHTS. It Landlord elects to repair, reconstruct and restore
pursuant to Subparagraph 20(b)(i) hereinabove, and if Landlord's contractor
estimates that as a result of such damage, Tenant cannot be given reasonable use
of and access to the Premises within two hundred forty (240) days after the date
of such damage then either Landlord or Tenant may terminate this Lease effective
upon delivery of written notice to the other within ten (10) days after Landlord
delivers notice to Tenant of its election to so repair reconstruct or restore;
provided, however, Tenant shall have no right to terminate this Lease if
Landlord can relocate Tenant to other comparable Premises in the Building or the
Project within one hundred eighty (180) days after the date of such damage.     

                                       15
<PAGE>
 
    
(d)  TENANTS COSTS AND INSURANCE PROCEEDS. In the event of any damage or
destruction of all or any part of the Premises, Tenant agrees to immediately (i)
notify Landlord thereof, and (ii) deliver to Landlord all property insurance
proceeds received by Tenant with respect to any tenant improvements installed by
or at the cost of Tenant and any alterations , but excluding proceeds for Tenant
s furniture, fixtures, equipment and other personal property whether or not this
Lease is terminated as permitted in this Paragraph 20 and Tenant hereby assigns
to Landlord all rights to receive such insurance proceeds. If for any reason
(including Tenants failure to obtain required insurance) Tenant fails to receive
insurance proceeds covering the full replacement cost of any tenant improvements
and any alterations which are damaged, Tenant will be deemed to have self-
insured the replacement cost of such items, and upon any damage or destruction
thereto Tenant agrees to immediately pay to Landlord the full replacement cost
of such items less any insurance proceeds actually received by Landlord from
Landlord's or Tenant's insurance with respect to such items.     
    
(e)  ABATEMENT OF RENT. In the event of any damage, repair reconstruction and/or
restoration described in this Paragraph 20, rent will be abated or reduced, as
the case may be, from the date of such casualty in proportion to the degree to
which Tenant s use of the Premises is impaired during such period of repair
until such use is restored. Except for abatement of rent as provided
hereinabove, Tenant will not be entitled to any compensation or damages for loss
of, or interference with, Tenant's business or use or access of all or any part
of the Premises or for lost profits or any other consequential damages of any
kind or nature, which result from any such damage, repair, reconstruction or
restoration.     
    
(f)  DAMAGE NEAR END OF TERM. Landlord and Tenant shall each have the right to
terminate this Lease if any damage to the Premises or the Building occurs during
the last twelve (12) months of the Term of this Lease where Landlord s
contractor estimates in a writing delivered to Landlord and Tenant that the
repair, reconstruction or restoration of such damage cannot be completed within
sixty (60) days after the date of such casualty. If either party desires to
terminate this Lease under this Subparagraph (f), it shall provide written
notice to the other party of such election within ten (10) days after receipt of
Landlord's contractor's repair estimates.     
    
(g)  WAIVER OF TERMINATION RIGHT. Landlord and Tenant agree that the foregoing
provisions of this Paragraph 20 are to govern their respective rights and
obligations in the event of any damage or destruction and supersede and are in
lieu of the provisions of any applicable law, statute, ordinance, rule,
regulation, order or ruling now or hereafter in force which provide remedies for
damage or destruction of leased premises (including, without limitation, to the
extent the Premises are located in California, the provisions of California
Civil Code Section 1932, Subsection 2, and Section 1933, Subsection 4 and any
successor statute or laws of a similar nature).     

21.  EMINENT DOMAIN.

                                       16
<PAGE>
 
    
(a)  SUBSTANTIAL TAKING. If the whole of the Premises or such part hereof as
shall substantially interfere with Tenant s use and occupancy of the Premises,
as contemplated by this Lease, is 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 prevent such taking, either party
will have the right to terminate this Lease effective as of the date possession
is required to be surrendered to such authority.     
    
(b)  PARTIAL TAKING; ABATEMENT OF RENT. In the event of a taking of a portion of
the Premises which does not substantially interfere with Tenant s use and
occupancy of the Premises including any temporary taking of ninety (90) days or
less, then, neither party will have the right to terminate this Lease and
Landlord will thereafter proceed to make a functional unit of the remaining
portion of the Premises (but only to the extent Landlord receives proceeds
therefor from the condemning authority), and rent will be abated with respect to
the part of the Premises which Tenant is deprived of on account of such taking.
Notwithstanding the immediately preceding sentence to the contrary , if any part
of the Building or the Project is taken (whether or not such taking
substantially interferes with Tenant's use of the Premises), Landlord may
terminate this Lease upon thirty (30) days' prior written notice to Tenant if
Landlord also terminates the leases of the other tenants of the Building which
are leasing comparably sized space for comparable lease terms.     
    
(c)  CONDEMNATION AWARD. In connection with any taking of the Premises or the
Building Landlord will be entitled to receive the entire amount of any award
which may be made or given in such taking or condemnation, without deduction or
apportionment for any estate or interest of Tenant, it being expressly
understood and agreed by Tenant that no portion of any such award will be
allowed or paid to Tenant for any so-called bonus or excess value of this Lease,
and such bonus or excess value will be the sole property of Landlord. Tenant
agrees not to assert any claim against Landlord or the taking authority for any
compensation because of such taking (including any claim for bonus or excess
value of this Lease); provided, however, if any portion of the Premises is
taken, Tenant will have the right to recover from the condemning authority (but
not from Landlord) any compensation as may be separately awarded or recoverable
by Tenant for the taking of Tenant's furniture, fixtures, equipment and other
personal property within the Premises, for Tenant's relocation expenses, and for
any loss of goodwill or other damage to Tenant's business by reason of such
taking.     

22.  DEFAULTS AND REMEDIES.

(a)  DEFAULTS. The occurrence of any one or more of the following events will be
deemed a default by Tenant:

(i)  The abandonment or vacation of the Premises by Tenant
    
(ii) The failure by Tenant to make any payment of rent or additional rent or any
other payment required to be made by Tenant hereunder, as and when due, where
such failure     

                                       17
<PAGE>
 
    
continues for a period of three (3) days after written notice thereof from
Landlord to Tenant; provided, however that any such notice will be in lieu of,
and not in addition to, any notice required under applicable law (including,
without limitation, to the extent the Premises are located in California, the
provisions of California Code of Civil Procedure Section 1161 regarding unlawful
detainer actions or any successor statute or law of a similar nature).     
    
(iii)    The failure by Tenant to observe or perform any of the express or
implied covenants or provisions of this Lease to be observed or performed by
Tenant, other than as specified in Subparagraph 22(a)(i) or (ii) above, where
such failure continues for a period of five (5) days after written notice
thereof from Landlord to Tenant the provisions of any such notice will be in
lieu of, and not in addition to, any notice required under applicable law
(including, without limitation, to the extent the Premises are located in
California, California Code of Civil Procedure Section 1161 regarding unlawful
detainer actions and any successor statute or similar law). If the nature of
Tenants default is such that more than five (5) days are reasonably required for
its cure, then Tenant will not be deemed to be in default if Tenant, with
Landlord's concurrence, commences such cure within such five (5) day period and
thereafter diligently prosecutes such cure to completion.     
    
(iv) (A) The making by Tenant of any general assignment for the benefit of
creditors; (B) the filing by or against Tenant of a petition to have Tenant
adjudged a bankrupt or a petition for reorganization or arrangement under any
law relating to bankruptcy (unless, in the case of a petition filed against
Tenant, the same is dismissed within sixty (60) days); (C) the appointment of a
trustee or receiver to take possession of substantially all of Tenant's assets
located at the Premises or of Tenant's interest in this Lease, where possession
is not restored to Tenant within thirty (30) days; or (D) the attachment,
execution or other judicial seizure of substantially all of Tenant s assets
located at the Premises or of Tenant s interest in this Lease where such seizure
is not discharged within thirty (30) days.     
    
(b)  LANDLORD'S REMEDIES; TERMINATION. In the event of any default by Tenant, in
addition to any other remedies available to Landlord at law or in equity under
applicable law (including without limitation to the extent the Premises are
located in California, the remedies of Civil Code Section 1951.4 and any
successor statute or similar law), Landlord will have the immediate right and
option to terminate this Lease and all rights of Tenant hereunder. If Landlord
elects to terminate this Lease then, to the extent permitted under applicable
law Landlord may recover from Tenant: (i) the worth at the time of award of any
unpaid rent which had been earned at the time of such termination; plus (ii) the
worth at the time of award of the amount by which the unpaid rent which would
have been earned after termination until the time of award exceeds the amount of
such rent loss that Tenant proves could have been reasonably avoided; plus (iii)
the worth at the time of award of the amount by which the unpaid rent for the
balance of the Term after the time of award exceeds the amount of such rent loss
that Tenant proves could be reasonably avoided; plus (iv) any other amount
necessary to compensate Landlord for all the detriment proximately caused by
Tenant's failure to perform its     

                                       18
<PAGE>
 
    
obligations under this Lease or which, in the ordinary course of things, results
therefrom including, but not limited to: attorneys" fees and costs; brokers
commissions; the costs of refurbishment, alterations, renovation and repair of
the Premises, and removal (including the repair of any damage caused by such
removal) and storage (or disposal) of Tenant's personal property, equipment,
fixtures, alterations, the tenant improvements and any other items which Tenant
is required under this Lease to remove, but does not remove, as well as the
unamortized value of any free rent, reduced rent, free parking, reduced rate
parking and any tenant improvement allowance or other costs or economic
concessions provided, paid, granted, or incurred by Landlord pursuant to this
Lease. As used in Subparagraphs 22(b)(i) and (ii) above the "worth at the time
of award" is computed by allowing interest at the interest Rate. As used in
Subparagraph 22(b)(iii) above, the "worth at the time of award" is computed by
discounting such amount at the discount rate of the Federal Reserve Bank of San
Francisco at the time of award plus one percent (1%).     
    
(c)  LANDLORD S REMEDIES; RE-ENTRY RIGHTS. In the event of any default by
Tenant, in addition to any other remedies available to Landlord under this
Lease, at law or in equity, Landlord will also have the right, with or without
terminating this Lease, to re-enter the Premises and remove all persons and
property from the Premises; such property may be removed and stored in a public
warehouse or elsewhere and/or disposed of at the sole cost and expense of and
for the account of Tenant in accordance with the provisions of Paragraph 13 of
this Lease or any other procedures permitted by applicable law. No re-entry or
taking possession of the Premises by Landlord pursuant to this Subparagraph
22(c) will be construed as an election to terminate this Lease unless a written
notice of such intention is given to Tenant or unless the termination thereof is
decreed by a court of competent jurisdiction.     
    
(d)  LANDLORD S REMEDIES; RE-LETTING.  If Landlord does not elect to terminate
this Lease, Landlord may from time to time, without terminating this Lease,
either recover all rent as it becomes due or relate the Premises or any part
thereof on terms and conditions as Landlord in its sole and absolute discretion
may deem advisable with the right to make alterations and repairs to the
Premises in connection with such reletting. If Landlord elects to relet the
Premises then rents received by Landlord from such reletting will be applied:
first, to the payment of any indebtedness other than rent due hereunder from
Tenant to Landlord; second, to the payment of any cost of such reletting; third,
to the payment of the cost of any alterations and repairs to the Premises
incurred in connection with such reletting; fourth, to the payment of rent due
and unpaid hereunder and the residue, if any will be held by Landlord and
applied to payment of future rent as the same may become due and payable
hereunder. Should that portion of such rents received from such reletting during
any month, which is applied to the payment of rent hereunder, be less than the
rent payable during that month by Tenant hereunder, then Tenant agrees to pay
such deficiency to Landlord immediately upon demand therefor by Landlord. Such
deficiency will be calculated and paid monthly.     
    
(e)  LANDLORD'S REMEDIES; PERFORMANCE FOR TENANT. All covenants and agreements
to be performed by Tenant under any of the terms of this Lease are to be
performed by Tenant     

                                       19
<PAGE>
 
    
at Tenant's sole cost and expense and without any abatement of rent. If Tenant
fails to pay any sum of money owed to any party other than Landlord, for which
it is liable under this Lease, or if Tenant fails to perform any other act on
its part to be performed hereunder, and such failure continues for ten (10) days
after notice thereof by Landlord, Landlord may, without waiving or releasing
Tenant from its obligations, but shall not be obligated to, make any such
payment or perform any such other act to be made or performed by Tenant. Tenant
agrees to reimburse Landlord upon demand for all sums so paid by Landlord and
all necessary incidental costs, together with interest thereon at the Interest
Rate, from the date of such payment by Landlord until reimbursement by Tenant.
This remedy shall be in addition to any other right or remedy of Landlord set
forth in this Paragraph 22.     
    
(f)  LATE PAYMENT. If Tenant fails to pay any installment of rent within seven
(7) days when due or if Tenant fails to make any other payment for which Tenant
is obligated under this Lease when due, such late amount will accrue interest at
the Interest Rate until such amount is paid by Tenant to Landlord. In addition
Tenant agrees to pay to Landlord concurrently with such late payment amount, as
additional rent, a late charge equal to ten percent (10%) of the amount due to
compensate Landlord for the extra costs Landlord will incur as a result of such
late payment. Landlord and Tenant agree that such late charge represents a fair
and reasonable estimate of the costs that Landlord will incur by reason of any
such late payment. Acceptance of any such interest and late charge will not
constitute a waiver of the Tenant's default with respect to the overdue amount,
or prevent Landlord from exercising any of the other rights and remedies
available to Landlord. If Tenant incurs a late charge more than three (3) times
in any period of twelve (12) months during the Lease Term, then, notwithstanding
that Tenant cures the late payments for which such late charges are imposed
Landlord will have the right to require Tenant thereafter to pay all
installments of Monthly Base Rent quarterly in advance in the form of a
cashier's check throughout the remainder of the Lease Term. Any payments of any
kind returned for insufficient funds will be subject to an additional handling
charge of $25.00 and thereafter, Landlord may require Tenant to pay all future
payments of rent or other sums due by money order or cashier's check.     
    
(g)  RIGHTS AND REMEDIES CUMULATIVE. All rights, options and remedies of
Landlord contained in this Lease will be construed and held to be cumulative,
and no one of them will be exclusive of the other, and Landlord shall have the
right to pursue any one or all of such remedies or any other remedy or relief
which may be provided by law or in equity whether or not stated in this Lease.
Nothing in this Paragraph 22 will be deemed to limit or otherwise affect
Tenant's indemnification of Landlord pursuant to any provision of This 
Lease.     
    
23.  LANDLORD'S DEFAULT. Landlord will not be in default in the performance of
any obligation required to be performed by Landlord under this Lease unless
Landlord fails to perform such obligation within thirty (30) days after the
receipt of written notice from Tenant specifying in detail Landlord's failure to
perform; provided, however, that  if the nature of Landlord's obligation is such
that more than thirty (30) days are required for performance, then Landlord will
not be deemed in default if it commences such performance within such 
thirty     

                                       20
<PAGE>
 
    
(30) day period and thereafter diligently pursues the same to completion. Upon
any default by Landlord, Tenant may exercise any of its rights provided at law
or in equity subject to the limitations on liability set forth in Paragraph 35
of This Lease.     

24.  ASSIGNMENT AND SUBLETTING.
    
(a)  RESTRICTION ON TRANSFER. Except as expressly provided in this Paragraph 24,
Tenant will not, either voluntarily or by operation of law, assign or encumber
this Lease or any interest herein or sublet the Premises or any part thereof, or
permit the use or occupancy of the Premises by any party other than Tenant (any
such assignment encumbrance sublease, or the like will sometimes be referred to
as a "Transfer"), without the prior written consent of Landlord, which consent
Landlord will not unreasonably withhold. For purposes of this Paragraph 24 , if
Tenant is a corporation, partnership or other entity, any transfer, assignment,
encumbrance or hypothecation of fifty percent (50%) or more (individually or in
the aggregate) of any stock or other ownership interest in such entity, and/or
any transfer, assignment, hypothecation or encumbrance of any controlling
ownership or voting interest in such entity, will be deemed a Transfer and will
be subject to all of the restrictions and provisions contained in this Paragraph
24; provided, however, this provision will not apply to public corporations, the
stock of which is traded through a public stock exchange or over the counter
system.     
    
(b)  TRANSFER NOTICE. If Tenant desires to elect a Transfer, then at least
thirty (30) days prior to the date when Tenant desires the Transfer to be
effective (the "Transfer Date") Tenant agrees to give Landlord a notice (the
"Transfer Notice") stating the name, address and business of the proposed
assignee, sublessee or other transferee (sometimes referred to hereinafter as
"Transferee") reasonable information (including references) concerning the
character, ownership, and financial condition of the proposed Transferee, the
Transfer Date, any ownership or commercial relationship between Tenant and the
proposed Transferee, and the consideration and all other material terms and
conditions of the proposed Transfer, all in such detail as Landlord may
reasonably require.    
    
(c)  LANDLORDS OPTIONS. Within fifteen (15) days of Landlord's receipt of any
Transfer Notice and any additional information requested by Landlord concerning
the proposed Transferee's financial responsibility, Landlord will notify Tenant
of its election to do one of the following: (i) consent to the proposed Transfer
subject to such reasonable conditions as Landlord may impose in providing such
consent; (ii) refuse such consent, which refusal shall be on reasonable grounds;
or (iii) terminate this Lease as to all or such portion of the Premises which is
proposed to be sublet or assigned and recapture all or such portion of the
Premises for reletting by Landlord.     
    
(d)  ADDITIONAL CONDITIONS. A condition to Landlord's consent to any transfer of
this Lease will be the delivery to Landlord of a true copy of the fully executed
instrument of assignment, sublease, transfer or hypothecation, in form and
substance reasonably satisfactory to Landlord.     

                                       21
<PAGE>
 
    
Tenant agrees to pay to Landlord, as additional rent, all sums and other
consideration payable to and for the benefit of Tenant by the assignee or
sublessee in excess of the rent payable under this Lease for the same period and
portion of the Premises. In calculating excess rent or other consideration which
may be payable to Landlord under this paragraph, Tenant will be entitled to
deduct commercially reasonable third party brokerage commissions and attorney's
fees and other amounts reasonably and actually expended by Tenant in connection
with such assignment or subletting if acceptable written evidence of such
expenditures is provided to Landlord. No Transfer will release Tenant of
Tenant's obligations under This Lease or alter the primary liability of Tenant
to pay the rent and to perform all other obligations to be performed by Tenant
hereunder. Landlord may require that any Transferee remit directly to Landlord
on a monthly basis, all monies due Tenant by said Transferee. Consent by
Landlord to one Transfer will not be deemed consent to any subsequent Transfer.
In the event of default by any Transferee of Tenant or any successor of Tenant
in the performance of any of the terms hereof, Landlord may proceed directly
against Tenant without the necessity of exhausting remedies against such
Transferee or successor. If Tenant effects a Transfer or requests the consent of
Landlord to any Transfer (whether or not such Transfer is consummated), then,
upon demand, Tenant agrees to pay Landlord a non-refundable administrative fee
of not less than One Hundred Dollars ($100.00) and actual expenses incurred,
plus Landlord's reasonable attorneys" fees.     
    
25.  SUBORDINATION. Without the necessity of any additional document being
executed by Tenant for the purpose of effecting a subordination, and at the
election of Landlord or any mortgagee or beneficiary with a deed of trust
encumbering the Building and/or the Project, or any lessor of a ground or
underlying lease with respect to the Building, this Lease will be subject and
subordinate at all times to: (i) all ground leases or underlying leases which
may now exist or hereafter be executed affecting the Building; and (ii) the lien
of any mortgage or deed of trust which may now exist or hereafter be executed
for which the Building, the Project or any leases thereof, or Landlord's
interest and estate in any of said items, is specified as Security.
Notwithstanding the foregoing, Landlord reserves the right to subordinate any
such ground leases or underlying leases or any such liens to This Lease. If any
such ground lease or underlying lease terminates for any reason or any such
mortgage or deed of trust is foreclosed or a conveyance in lieu of foreclosure
is made for any reason, at the election of Landlord's successor in interest,
Tenant agrees to attorn to and become the tenant of such successor in which
event Tenant's right to possession of the Premises will not be disturbed as long
as Tenant is not in default under this Lease. Tenant hereby waives its rights
under any law which gives or purports to give Tenant any right to terminate or
otherwise adversely affect this Lease and the obligations of Tenant hereunder in
the event of any such foreclosure proceeding or sale. Tenant covenants and
agrees to execute and deliver, upon demand by Landlord and in the form
reasonably required by Landlord, any additional documents evidencing the
priority or subordination of this Lease and Tenant's attornment agreement with
respect to any such ground lease or underlying leases or the lien of any such
mortgage or deed of trust. If Tenant fails to sign and return any such documents
within ten (10) days of receipt, Tenant will be in default hereunder.

26.  ESTOPPEL CERTIFICATE. Within ten (10) days following any written request
which Landlord may make from time to time, Tenant agrees to execute and deliver
to Landlord an estoppel certificate, in Landlord's standard form or as may
reasonably be required by Landlord's lender. Landlord and Tenant intend that any
Statement delivered pursuant to this Paragraph 26 may be relied upon by any
mortgagee, beneficiary, purchaser or prospective purchaser of the Building or
any interest therein. Tenant's failure to deliver such statement within such
time will be conclusive upon Tenant (i) that this Lease is in full force and
effect without modification except as may be represented by Landlord, (ii) that
there are no uncured defaults in Landlord's performance, and (iii) that not more
than one (1) month's rent has been paid in advance. Without limiting the
foregoing, if Tenant fails to deliver any such statement within such ten (10)
day period, Landlord may deliver to Tenant an additional request for such
Statement and Tenant's failure to deliver such Statement to Landlord within ten
(10) days after delivery of such additional request will constitute a default
under this Lease. Tenant agrees to indemnify and protect Landlord from and
against any and all claims, damages, losses, liabilities and expenses (including
attorneys fees and costs) attributable to any failure by Tenant to timely
deliver any such estoppel certificate to Landlord as required by this Paragraph
26.     
    
27.  BUILDING PLANNING. If Landlord requires the Premises for use in conjunction
with another suite or for other reasons connected with the planning program for
the Building or the Project, Landlord will have the right upon sixty (60) days'
prior written notice to Tenant, to move Tenant to other space in the Building of
substantially similar size as the Premises, and with tenant improvements of
substantially similar age, quality and layout as then existing in the Premises.
Any such relocation will be at Landlord's cost and expense, including the cost
of providing such substantially similar tenant improvements (but not any
furniture or personal property) and Tenant's reasonable moving, telephone
installation and stationary reprinting costs. If Landlord so relocates Tenant,
the terms and conditions of this Lease will remain in full force and effect and
apply to the new space, except that (a) a revised Exhibit "A" will become part
of this Lease and will reflect the location of the new space, (b) Paragraph 1 of
This Lease will be amended to include and state all correct data as to the new
space, (c) the new space will thereafter be deemed to be the "Premises," and (d)
all economic terms and conditions (e.g. rent, total Operating Expense Allowance,
etc.) will be adjusted on a per square foot basis based on the total number of
rentable square feel of area contained in the new space. Landlord and Tenant
agree to cooperate fully with one another in order to minimize the inconvenience
to Tenant resulting from any such relocation.     
    
28.  RULES AND REGULATIONS. Tenant agrees to faithfully observe and comply with
the "Rules and Regulations," a copy of which is attached hereto and incorporated
herein by this reference as Exhibit "E," and all reasonable and
nondiscriminatory modifications thereof and additions thereto from time to time
put into effect by Landlord. Landlord will not be responsible to Tenant for the
violation or non-performance by any other tenant or occupant of the Building of

29.  MODIFICATION AND CURE RIGHTS OF LANDLORD'S MORTGAGEES AND LESSORS. Tenant,
within ten (10) days after request therefor, agrees to execute any reasonable
amendments to this Lease which may be requested by any lender or ground lessor
of the Project, provided any such amendments do not increase the obligations of
Tenant under this Lease or adversely affect the leasehold estate created by this
Lease. In the event of any default on the part of Landlord, Tenant will give
notice by registered or certified mail to any beneficiary of a deed of trust or
mortgage covering the Premises or ground lessor of Landlord whose address has
been furnished to Tenant, and Tenant agrees to offer such beneficiary, mortgagee
or ground lessor a reasonable opportunity to cure the default (including with
respect to any such beneficiary or mortgagee, time to obtain possession of the
Premises, subject to this Lease and Tenant's rights hereunder, by power of sale
or a judicial foreclosure, if such should prove necessary to effect a 
cure).     
    
30.  DEFINITION OF LANDLORD. The term "Landlord" as used in this Lease, so far
as covenants or obligations on the part of Landlord are concerned, means and
includes only the owner or owners, at the time in question, of the fee title of
the Premises or the lessees under any ground lease, if any. In the event of any
transfer, assignment or other conveyance or transfers of any such title (other
than a transfer for security purposes only), Landlord herein named (and in case
of any subsequent transfers or conveyances, the then grantor) will be
automatically relieved from and after the date of such transfer, assignment or
conveyance of all liability as respects, the performance of any covenants or
obligations on the part of Landlord contained in this Lease thereafter to be
performed, so long as the transferee assumes in writing all such covenants and
obligations of Landlord arising after the date of such transfer. Landlord and
Landlord's transferees and assignees have the absolute right to transfer all or
any portion of their respective title and interest in the Project, the Building,
the Premises and/or this Lease without the consent of Tenant, and such transfer
or subsequent transfer will not be deemed a violation on Landlord's part of any
of the terms and conditions of This Lease.     
    
31.  WAIVER. The waiver by either party of any breach or any term, covenant or
condition herein contained will not be deemed to be a waiver of any subsequent
breach of the same or any other term, covenant or condition herein contained,
nor will any custom or practice which may develop between the parties in the
administration of the terms hereof be deemed a waiver of or in any way affect
the right of either party to insist upon performance in strict accordance with
said terms. The subsequent acceptance of rent or any other payment hereunder by
Landlord will not be deemed to be a waiver of any preceding breach by Tenant of
any term, covenant or condition of this Lease, other than the failure of Tenant
to pay the particular rent so accepted, regardless of Landlord's knowledge of
such preceding breach at the time of acceptance of such rent. No acceptance by
Landlord of a lesser sum than the basic rent and additional rent or other sum
then due will be deemed to be other than on account of the earliest installment
of such rent or other amount due, nor will any endorsement or statement on any
check or any letter accompanying any check 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 installment or other amount or pursue any
other remedy provided in this Lease. The consent or     

                                       24
<PAGE>
 
    
approval of Landlord to or of any act by Tenant requiring Landlord's consent or
approval will not be deemed to waive or render unnecessary Landlord's consent or
approval to or of any subsequent similar acts by Tenant.     
    
32.  PARKING. So long as this Lease is in effect and provided Tenant is not in
default hereunder, Landlord grants to Tenant, Tenant's visitors and guests a 
non-exclusive license to use the parking areas which serve the Building subject
to the terms and conditions of this Paragraph 32 and the Rules and Regulations
regarding parking contained in Exhibit "E" attached hereto. Tenant will not use
or allow any of Tenant's employees or guests to use any parking spaces which
have been specifically assigned by Landlord to other tenants or occupants or for
other uses such as visitor parking or which have been designated by any
governmental entity as being restricted to certain uses. Landlord may assign any
unreserved and unassigned parking spaces and/or make all or any portion of such
spaces reserved, if Landlord reasonably determines that it is necessary for
orderly and efficient parking or for any other reasonable reason. Tenant agrees
to cause its employees, subtenants, assignees, contractors, suppliers, customers
and invitees to comply with the Rules and Regulations. Landlord reserves the
right from time to lime to modify and/or adopt such other reasonable and non-
discriminatory rules and regulations for the parking facilities as it deems
reasonably necessary for the operation of the parking facilities.    
    
33.  FORCE MAJEURE. If either Landlord or Tenant is delayed, hindered in or
prevented from the performance of any act required under this Lease by reason of
strikes, lock-outs, labor troubles, inability to procure standard materials,
failure of power, restrictive governmental laws, regulations or orders or
governmental action or inaction (including failure, refusal or delay in issuing
permits, approvals and/or authorizations which is not the result of the action
or inaction of the party claiming such delay), riots, civil unrest or
insurrection, war, fire, earthquake, flood or other natural disaster, unusual
and unforeseeable delay which results from an interruption of any public
utilities (e.g., electricity, gas, water, telephone) or other unusual and
unforeseeable delay not within the reasonable control of the party delayed in
performing work or doing acts required under the provisions of this Lease, then
performance of such act will be excused for the period of the delay and the
period for the performance of any such act will be extended for a period
equivalent to the period of such delay. The provisions of this Paragraph 33 will
not operate to excuse Tenant from prompt payment of rent or any other payments
required under the provisions of this Lease.     
    
34.  SIGNS. Landlord will designate the location on the Premises, if any, any
for one or more Tenant identification sign(s). Tenant has no right to install
Tenant identification signs in any other location in on or about the Premises or
the Project and will not display or erect any other signs, displays or other
advertising materials that are visible from the exterior of the Building or from
within the Building in any interior or exterior common areas. The size, design,
color and other physical aspects of any and all permitted sign(s) will be
subject to (i) Landlord's written approval prior to installation, which approval
may be withheld in Landlord s discretion (ii) any covenants, conditions or
restrictions and sign criteria governing the     

                                       25
<PAGE>
 
    
Project, and (iii) any applicable municipal or governmental permits and
approvals. Tenant will be solely responsible for all costs for installation,
maintenance, repair and removal of any Tenant identification sign(s). If Tenant
fails to remove Tenant's sign(s) upon termination of this Lease and repair any
damage caused by such removal, Landlord may do so at Tenant's sole cost and
expense. Tenant agrees to reimburse Landlord for all costs incurred by Landlord
to effect any installation, maintenance or removal on Tenant's account, which
amount will be deemed additional rent, and may include, without limitation, all
sums disbursed, incurred or deposited by Landlord including Landlord's costs,
expenses and actual attorneys" fees with interest thereon at the Interest Rate
from the date of Landlord's demand until paid by Tenant. Any sign rights granted
to Tenant under this Lease are personal to Tenant and may not be assigned,
transferred or otherwise conveyed to any assignee or subtenant of Tenant without
Landlord's prior written consent, which consent Landlord may withhold in its
sole and absolute discretion.     
    
35.  LIMITATION ON LIABILITY. In consideration of the benefits accruing
hereunder, Tenant on behalf of itself and all successors and assigns of Tenant
covenants and agrees that, in the event of any actual or alleged failure, breach
or default hereunder by Landlord: (a) Tenant's recourse against Landlord for
monetary damages will be limited to Landlord's interest in the Building
including, subject to the prior rights of any Mortgagee, Landlord's interest in
the rents of the Building and any insurance proceeds payable to Landlord; (b)

their personal assets for satisfaction of any liability in respect to this
Lease; and (g) these covenants and agreements are enforceable both by Landlord
and also by any partner of Landlord.

due.  It is further understood that any improvement of the leased premises by
the Tenant which may result in the delay in construction of tenant improvements
or in the obtaining of a building permit without prior written consent of
Landlord is hereby prohibited.

                                         (initials)

In the event Tenant takes possession of the premises prior to completion of any
construction, Tenant agrees to hold Landlord harmless from any and all claims
for damages to goods, equipment or inconvenience.

Tenant hereby agrees that if Tenant breaches the Lease and/or abandons the
premises before the end of the Lease term, if Tenant's right to possession is
terminated by Landlord because of Tenant's breach of the Lease, Landlord shall,
at its option, (i) void this Early Possession Agreement; and (ii) recover from
Tenant, in addition to any damages due Landlord under the terms and conditions
of the Lease, rent prorated for the duration of the Early Possession Period at a
rental rate equivalent to one and a half (1 1/2) times the monthly rental rate

TABLE 515-1
INSTRUCTIONS FOR COMMERCIAL SALES PRACTICES FORMAT

If you responded "YES" to question (3), on the COMMERCIAL SALES PRACTICES
FORMAT, complete the chart in question (4)(a) for the customer(s) who receive
your best discount. If you responded "NO" complete the chart in question (4)(a)
showing your written policies or standard sales practices for all customers or
customer categories to whom you sell at a price (discounts and concessions in
combination) that is equal to or better than the price(s) offered to the
Government under this solicitation or with which the Offeror has a current
agreement to sell at a discount which equals or exceeds the discount(s) offered
under this solicitation. Such agreement shall be in effect on the date the offer
is submitted or contain an effective date during the proposed multiple award
schedule contract period. If your offer is lower than your price to other
customers or customer categories you will be aligned with the customer or
category of customer that receives your best price for purposes of the Price
Reductions clause at 552.238-76. The Government expects you to provide
information required by the format in accordance with these instructions that
is, to the best of your knowledge and belief, current, accurate, and complete as
of 14 calendar days prior to its submission. You must also disclose any changes
in your pricelist(s), discounts and/or discounting policies which occur after
the offer is submitted, but before the close of negotiations. If your discount
practices vary by model or product line, the discount information should be by
model or product line as appropriate. You may limit the number of models or
product lines reported to those which exceed 75% of actual historical Government
sales (commercial sales may be substituted if Government sales are unavailable)
value of the special item number (SIN).

Column 1-Identify the applicable customer or category of customer. A "customer"
is any entity, except the Federal Government, which acquires supplies or
services from the Offeror. The term customer includes, but is not limited to
original equipment manufacturers, value added resellers, state and local
governments, distributors, educational institutions (an elementary, junior high,
or degree granting school which maintains a regular facility and established
curriculum and an organized body of students), dealers, national accounts, and
end users. In any instance where the Offeror is asked to disclose information
for a customer, the Offeror may disclose information by category of customer if
the Offeror's discount policies or practices are the same for all customers in
the category. (Use a separate line for each customer or category of customer.)

Column 2-Identify the discount. The term "discount" is as defined in
solicitation clause 552.212-70 Preparation of Offer (Multiple Award Schedule).
Indicate the best discount (based on your written discounting policies or
standard commercial discounting practices if you do not have written discounting
policies) at which you sell to the customer or category of customer identified
in column 1, without regard to quantity; terms and conditions of the agreements
under which the discounts are given; and whether the agreements are written or
oral. Net prices or discounts off of other pricelists should be expressed as
percentage discounts from the pricelist which is the basis for your offer. If
the discount disclosed is a combination of various discounts (prompt payment,
quantity, etc.), the percentage should be broken out for each type of discount.
If the pricelists which are the basis of the discounts given to the customers
identified in the chart are different than the pricelist submitted upon which
your offer is based, identify the type or title and date of each pricelist. The
Contracting Officer may require submission of these pricelists. To expedite
evaluation, Offerors may provide these pricelists at the time of submission.
    
Column 3-Identify tho quantity or volume of sales. Insert the minimum quantity
or sales volume which the identified customer or category of customer must

discount. When purchases/orders must be placed within a specified period to earn
a discount indicate the time period.      
    
Column 4-Indicate tho FOB delivery term for each identified customer. (See FAR
47.3 for an explanation of FOB delivery terms.)      

Column 5-Indicate concession regardless of quantity granted to the identified
customer or category of customer. Concessions are defined in solicitation clause
552.212-70 Preparation of Offers (Multiple Award Schedule). If the space

reference. If you respond "YES" to question 4(b) in the Commercial Sales
Practices Format, provide an explanation of the circumstances under which you
deviate from your written policies or standard commercial sales practices
disclosed in the chart on the Commercial Sales Practices Format and explain how

charity organizations or to compensate an otherwise disgruntled customer; a
limited sale of obsolete or damaged goods; the sale of sample goods to a new
customer; or the sales of prototype goods for testing purposes.
    
If deviations from your written policies or standard commercial sales practices
disclosed in the chart on the Commercial Sales Practices Format are so
significant and/or frequent that the Contracting Officer cannot establish
whether the price(s) offered is fair and reasonable, then you may be asked to
provide additional information.  The Contracting Officer may ask for information
to demonstrate that you have made substantial sales of the item(s) in the
commercial market consistent with the information reflected on the chart on the
Commercial Sales Practices Format, a description of the conditions surrounding
those sales deviations, or other information that may be necessary in order for
the Contracting Officer to determine whether your offered price(s) is fair and
reasonable. In cases where additional information is-requested, the Contracting
Officer will target the request in order to limit the submission of data to that
needed to establish the reasonableness of the offered price.

exercise all rights under the Debt Collection Act of 1982, including withholding
or setting off payments and interest on the debt (see FAR 52.232-17, Interest).

(e) Failure to submit sales reports, falsification of sales reports, and/or
failure to pay the IFF in a timely manner may result in termination or
cancellation of this contract.  Willful failure or refusal to furnish the
required reports, falsification of sales reports, or failure to make timely
payment of the IFF constitutes sufficient cause for terminating the contract for
cause under the termination provisions of this contract.

(c) If the Contractor agrees, GSA's Federal Supply Service (FSS) will place all
orders by EDI using computer-to-computer EDI. If computer-to-computer EDI is not
possible, FSS will use an alternative EDI method allowing the Contractor to
receive orders by facsimile transmission. Subject to the Contractor's agreement,
other agencies may place orders by EDI.
    
(d) When computer-to-computer EDI procedures will be used to place orders, the
Contractor shall enter into one or more Trading Partner Agreements (TPA) with
each Federal agency placing orders electronically in order to ensure mutual
understanding by the parties of certain electronic transaction conventions and
to recognize the rights and responsibilities of the parties as they apply to
this method of placing orders.  The TPA must identify, among other things, the
third party provider(s) through which electronic orders are placed, the
transaction sets used, security procedures, and guidelines for implementation.
Federal agencies may obtain a sample format to customize as needed from the
office specified in (g) below.      

(e) The Contractor shall be responsible for providing its own hardware and
software necessary to transmit and receive data electronically. Additionally,
each party to the TPA shall be responsible for the costs associated with its use
of third party provider services.

(f) Nothing in the TPA will invalidate any part of this contract between the
Contractor and the General Services Administration. All terms and conditions of
this contract that otherwise would be applicable to a mailed order shall apply
to the electronic order.

(g) The basic content and format of the TPA will be provided by:

SPECIAL NOTICE TO AGENCIES:

Small Business Participation

    
SBA strongly supports the participation of small business concerns in the
Federal Supply Schedules Program.  To enhance Small Business Participation SBA
policy allows agencies to include in their procurement base and goals, the
dollar value of orders expected to be placed against the Federal Supply
schedules, and to report accomplishments against these goals.      

For orders exceeding the micropurchase threshold, FAR 8.404 requires agencies to
consider the catalogs/pricelists of at least three schedule contractors or
consider reasonably available
<PAGE>

information by using the GSA Advantage!TM on-line shopping service
(www.fss.gsa.gov). The catalogs/pricelists, GSA Advantage!TM and the Federal
Supply Service Home Page (www.fss.gsa.gov) contain information on a broad array
of products and services offered by small business concerns.

This information should be used as a tool to assist ordering activities in
meeting or exceeding established small business goals. It should also be used as
a tool to assist in including small, small disadvantaged, and women-owned small
businesses among those considered when selecting pricelists for a best value
determination.

For orders exceeding the micropurchase threshold, customers are to give
preference to small business concerns when two or more items at the same
delivered price will satisfy their requirement.

1. Geographic Scope of Contract:

**The minimum acceptable geographic scope of contract is the 48 contiguous
states and the District of Columbia. If the scope includes Alaska, Hawaii, or
the Commonwealth of Puerto Rico, identify these locations. Any overseas
locations must also be specifically identified.**

2. Contractor's Ordering Address and Payment Information:

**The Contractor should insert the complete address(es) for ordering (see
paragraph G.8) and payment (see paragraph G.10.**

Contractors are required to accept the Government purchase card for payments
equal to or less than the micro-purchase threshold for oral or written delivery
orders.  Government purchase cards will/will not be acceptable for payment above
                                   ----                                         
the micro-purchase threshold.  In addition, bank account information for wire
transfer payments will be shown on the invoice.

**Choose the appropriate language "will" or "will not" in the second sentence.
Copy the first and third sentence.**

The following telephone number(s) can be used by ordering agencies to obtain
technical and/or ordering assistance:

12. USE OF FEDERAL SUPPLY SERVICE INFORMATION TECHNOLOGY SCHEDULE CONTRACTS. In
accordance with FAR 8.404:

[NOTE:  Special ordering procedures have been established for Special Item
Numbers (SINs) 132-51 IT Professional Services and 132-52 EC Services; refer to
the terms and conditions for those SINs.]
    
Orders placed pursuant to a Multiple Award Schedule (MAS), using the procedures
in FAR 8.404, are considered to be issued pursuant to full and open competition.
Therefore, when placing orders under Federal Supply Schedules, ordering offices
need not seek further competition, synopsize the requirement, make a separate
determination of fair and reasonable pricing, or consider small business set-
asides in accordance with subpart 19.5.  GSA has already determined the prices
of items under schedule contracts to be fair and reasonable.  By placing an
order against a schedule using the procedures outlined below, the ordering
office has concluded that the order represents the best value and results in the
lowest overall cost alternative (considering price, special features,
administrative costs, etc.) to meet the Government's needs.      

a. Orders placed at or below the micro-purchase threshold. Ordering offices can
place orders at or below the micro-purchase threshold with any Federal Supply
Schedule Contractor.
    
b. Orders excluding the micro-purchase threshold but not exceeding the maximum
order threshold. Orders should be placed with the Schedule Contractor that can
provide the supply or service that represents the best value. Before placing an
order, ordering offices should consider reasonably available information      
<PAGE>
 
Modification                                           Page 33 of 53 Pages


about the supply or service offered under MAS contracts by using the "GSA
Advantage!" on-line shopping service, or by reviewing the catalogs/pricelists of
at least three Schedule Contractors and selecting the delivery and other options
available under the schedule that meets the agency's needs. In selecting the
supply or service representing the best value, the ordering office may
consider--

(1) Special features of the supply or service that are required in effective
program performance and that are not provided by a comparable supply or service;

(2) Trade-in considerations;

(3) Probable life of the item selected as compared with that of a comparable
item;

(4) Warranty considerations;

(5) Maintenance availability;

(6) Past performance; and

(7) Environmental and energy efficiency considerations.

c. Orders exceeding the maximum order threshold.  Each schedule contract has an
established maximum order threshold.  This threshold represents the point where
it is advantageous for the ordering office to seek a price reduction.  In
addition to following the procedures in paragraph b, above, and before placing
an order that exceeds the maximum order threshold, ordering offices shall--

(1) Review additional Schedule Contractors' catalog pricelists or use the "GSA
Advantage!" on-line shopping service;

(2) Based upon the initial evaluation, generally seek price reductions from the
Schedule Contractor(s) appearing to provide the best value (considering price
and other factors); and

(3) After price reductions have been sought, place the order with the Schedule
Contractor that provides the best value and results in the lowest overall cost
alternative. If further price reductions are not offered, an order may still be
placed, 8 if the ordering office determines that it is appropriate.
<PAGE>
 
Modification                                           Page 34 of 53 Pages

NOTE:  For orders exceeding the maximum order threshold, the Contractor may:

(1) Offer a new lower price for this requirement (the Price Reductions clause is
not applicable to orders placed over the maximum order in FAR 52.216-19 Order
Limitations);

(2) Offer the lowest price available under the contract; or

(3) Decline the order (orders must be returned in accordance with
FAR 52.216-19).

d. Blanket purchase agreements (BPAs).  The establishment of Federal Supply
Schedule BPAs is permitted when following the ordering procedures in FAR 8.404.
All schedule contracts contain BPA provisions. Ordering offices may use BPAs to
establish accounts with Contractors to fill recurring requirements. BPAs should
address the frequency of ordering and invoicing, discounts, and delivery
locations and times.
    
e. Price reductions.  In addition to the circumstances outlined in paragraph c,
above, there may be instances when ordering offices will find it advantageous to
request a price reduction. For example, when the ordering office finds a
schedule supply or service elsewhere at a lower price or when a BPA is being
established to fill recurring requirements, requesting a price reduction could
be advantageous. The potential volume of orders under these agreements,
regardless of the size of the individual order, may offer the ordering office
the opportunity to secure greater discounts. Schedule Contractors are not
required to pass on to all schedule users a price reduction extended only to an
individual agency for a specific order.       

f. Small business.  For orders exceeding the micro-purchase threshold, ordering
offices should give preference to the items of small business concerns when two
or more items at the same delivered price will satisfy the requirement.

g. Documentation.  Orders should be documented, at a minimum, by identifying the
Contractor the item was purchased from, the item purchased, and the amount paid.
If an agency requirement in excess of the micro-purchase threshold is defined so
as to require a particular brand name, product, or feature of a product peculiar
to one manufacturer, thereby precluding consideration of a product manufactured
by another company, the
<PAGE>
 
Modification                                           Page 35 of 53 Pages


ordering office shall include an explanation in the file as to why the
particular brand name, product, or feature is essential to satisfy the agency's
needs.

13. FEDERAL INFORMATION TECHNOLOGY/TELECOMMUNICATIONS STANDARDS REQUIREMENTS:
Federal departments and agencies acquiring products from this Schedule must
comply with the provisions of the Federal Standards Program, as appropriate
(reference:  NIST Federal Standards Index). Inquiries to determine whether or
not specific products listed herein comply with Federal Information Processing
Standards (FIPS) or Federal telecommunication Standards (FED-STDS), which are
cited by ordering offices, shall be responded to promptly by the Contractor.
    
13.1 FEDERAL INFORMATION PROCESSING STANDARDS PUBLICATIONS (FIPS PUBS):
Information Technology products under this Schedule that do not conform to
Federal Information Processing Standards (FIPS) should not be acquired unless a
waiver has been granted in accordance with the applicable "FIPS Publication."

Virginia 22161. FIPS PUBS include voluntary standards when these are adopted for
Federal use. Individual orders for FIPS PUBS should be referred to the NTIS
Sales Office, and orders for subscription service should be referred to the
NTIS Subscription Officer, both at the above address, or telephone number (703)
487-4650.      

13.2 FEDERAL TELECOMMUNICATION STANDARDS (FED STDS): Telecommunication products
under this Schedule that do not conform to Federal Telecommunication Standards
(FED-STDS) should not be acquired unless a waiver has been granted in accordance
with the applicable "FED-STD." Federal telecommunication Standards are issued by
the U.S. Department of Commerce, National Institute of Standards and Technology
(NIST), pursuant to National Security Act.  Ordering information and information
concerning the availability of FED-STDS should be obtained from the GSA, Federal

14. SECURITY REQUIREMENTS.  In the event security requirements are necessary,
the ordering activities may incorporate, in their delivery orders, a security
clause in accordance with current laws, regulations, and individual agency
policy; however, the burden of administering the security requirements shall be
with the ordering agency.  If any costs are incurred as a result of the
inclusion of security requirements, such costs will not exceed ten percent (10%)
or $100,000, of the total dollar value of the order, whichever is lessor.
     
    
15. CONTRACT ADMINISTRATION FOR ORDERING OFFICES:  Any ordering office, with
respect to any one or more delivery orders placed by it under this contract, may
exercise the same rights of termination as might the GSA Contracting Officer

21. BLANKET PURCHASE AGREEMENTS (BPAs)

Federal Acquisition Regulation (FAR) 13.201(a) defines Blanket Purchase
Agreements (BPAs) as "...a simplified method of filling anticipated repetitive
needs for supplies or services by establishing 'charge accounts' with qualified
sources of supply." The use of Blanket Purchase Agreements under the Federal
Supply Schedule Program is authorized in accordance with FAR 13.202(c)(3), which
reads, in part, as follows:

"BPAs may be established with Federal Supply Schedule Contractors, ( if not
inconsistent with the terms of the applicable schedule contract."
<PAGE>
 
Modification                                           Page 39 of 53 Pages


Federal Supply Schedule contracts contain BPA provisions to enable schedule
users to maximize their administrative and purchasing savings.  This feature
permits schedule users to set up "accounts" with Schedule Contractors to fill
recurring requirements. These accounts establish a period for the BPA, and
generally address issues such as the frequency of ordering and invoicing,
authorized callers, discounts, delivery locations and times.  Agencies may
qualify for the best quantity/volume discounts available under the contract,
based on the potential volume of business that may be generated through such an
agreement, regardless of the size of the individual orders. In addition,
agencies may be able to secure a discount higher than that available in the
contract based on the aggregate volume of business possible under a BPA.
Finally, Contractors may be open to a progressive type of discounting where the
discount would increase once the sales accumulated under the BPA reach certain
prescribed levels.  Use of a BPA may be particularly useful with the new Maximum
Order feature. See the Suggested Format, contained in this Schedule Pricelist,
for customers to consider when using this purchasing tool.

22. CONTRACTOR TEAM ARRANGEMENTS

Federal Supply Schedule Contractors may use "Contractor Team Arrangements"
(see FAR 9.6) to provide solutions when responding to a customer agency
requirements. The policy and procedures outlined in this part will provide
more flexibility and allow innovative acquisition methods when using the
Federal Supply Schedules. See the additional information regarding
Contractor Team Arrangements in this Schedule Pricelist.

18. DELETE from ATTACHMENT I the section entitled TERMS AND CONDITIONS
APPLICABLE TO INFORMATION TECHNOLOGY PROFESSIONAL SERVICES (SPECIAL ITEM 132-51)
AND ELECTRONIC COMMERCE SERVICES (SPECIAL ITEM 132-52) FOR GENERAL PURPOSE
INFORMATION TECHNOLOGY SERVICES and REPLACE with the following:

TERMS AND CONDITIONS APPLICABLE TO INFORMATION TECHNOLOGY (IT) PROFESSIONAL
SERVICES (SPECIAL ITEM NUMBER 132-51) AND ELECTRONIC COMMERCE (EC) SERVICES
(SPECIAL ITEM NUMBER 132-52)
    
**The phrase, "Information Technology (IT) Professional Services/Electronic
Commerce (EC) Services" in the following; paragraphs may need to be revised in
order to be consistent with the Offeror's proposal; e.g., if only IT
Professional Services are offered, all references to EC Services should be
deleted.**     

1. SCOPE

a. The prices, terms and conditions stated under Special Item Number 132-51
Information Technology Professional Services and Special Item Number 132-52
Electronic Commerce Services apply exclusively to IT/EC Services within the
scope of this Information Technology Schedule.

b. The Contractor shall provide services at the Contractor's facility and/or at
the Government location, as agreed to by the Contractor and the ordering office.

**NOTE:  Include paragraph 2, only if hourly rates for IT Professional Services
are offered.**

2. ORDERING PROCEDURES

a. Procedures for IT professional services priced on GSA schedule at hourly
rates.
    
(1) FAR 8.402 contemplates that GSA may occasionally find it necessary to
establish special ordering procedures for individual Federal Supply Schedules or
for some Special Item Numbers (SINs) within a Schedule. GSA has established
special ordering procedures for IT professional services (SIN 132-51)     
<PAGE>
 
Modification                                           Page 41 of 53 Pages


that are priced on schedule at hourly rates. These special ordering procedures
which are outlined herein take precedence over the procedures in FAR 8.404.

(2) The GSA has determined that the rates for IT professional services contained
in this pricelist are fair and reasonable. However, the ordering office using
this contract is responsible for considering the level of effort and mix of
labor proposed to perform a specific task being ordered and for making a
determination that the total firm-fixed price or ceiling price is fair and
reasonable.

(3) When ordering IT professional services ordering offices shall

(i) Prepare a Request for quotation:

(A) A performance-based statement of work that outlines, at a minimum, the work
to be performed, location of work, period of performance, deliverable schedule,
applicable standards, acceptance criteria, and any special requirements (i.e.,
security clearances, travel, special knowledge, etc.) should be prepared.

(B) A request for quotation should be prepared which includes the performance-
based statement of work and requests the contractors submit either a firm-fixed
price or a ceiling price to provide the services outlined in the statement of
work. A firm-fixed price order shall be requested, unless the ordering office
makes a determination that it is not possible at the time of placing the order
to estimate accurately the extent or duration of the work or to anticipate cost
with any reasonable degree of confidence. When such a determination is made, a
labor hour or time-and-materials-proposal may be requested.  The firm fixed
price shall be based on the hourly rates in the schedule contract and shall
consider the mix of labor categories and level of effort required to perform the
services described in the statement of work.  The firm-fixed price of the order
should also include any travel costs or other incidental costs related to
performance of the services ordered, unless the order provides for reimbursement
of travel costs at the rates provided in the Federal Travel or Joint Travel
Regulations.  A ceiling price must be established for labor; hour and time and
material orders.

(C) The request for quotation may request the contractors, if necessary or
appropriate, submit a project plan for performing the task and information on
the contractor's experience and/or past performance performing similar tasks.
<PAGE>
 
Modification                                           Page 42 of 53 Pages


(D) The request for quotation shall notify the contractors what basis will be
used for selecting the contractor to receive the order.  The notice shall
include the basis for determining whether the contractors are technically
qualified and provide an explanation regarding the intended use of any
experience and/or past performance information in determining technical
acceptability of responses.  If consideration will be limited to schedule
contractors who are small business concerns as permitted by paragraph (ii)(A)
below, the request for quotations shall notify the contractors that will be the
case.

(ii) Transmit the Request for quotation to Contractors:

(A) Based upon an initial evaluation of catalogs and pricelists, the ordering
office should identify the contractors that appear to offer the best value
(considering the scope of services offered, hourly rates and other factors such
as contractors' locations, as appropriate). When buying IT professional services
under SIN 132-51 ONLY, the ordering office, at its discretion, may limit
consideration to those schedule contractors that are small business concerns.
This limitation is not applicable when buying supplies and/or services under
other SINs as well as SIN 132-51. The limitations may only be used when at least
three (3) small businesses that appear to offer services that will meet the
agency's needs are available, if the order is estimated to exceed the micro-
purchase threshold.

(B)- The request for quotation-should be to three (3) contractors if the
proposed order is estimated to exceed the micro-purchase threshold, but not to
exceed the maximum order threshold. For proposed orders exceeding the maximum
order threshold, the request for quotation should be provided to additional
contractors that offer services that will meet the agency's needs. Ordering
offices should strive to minimize the contractors' costs associated with
responding to requests for proposals for specific orders.  Requests should be
tailored to the minimum level necessary for adequate evaluation and selection
for order placement.

(iii) Evaluate Proposals and select the contractor to receive the order:

After responses have been evaluated against the factors identified in the
request for quotation, the order should be placed with the schedule contractor
that represents the best value and results in the lowest overall cost
alternative (considering price, special qualifications, administrative costs,
etc.) to meet the Government's needs.
<PAGE>
 
Modification                                           Page 43 of 53 Pages


(4) The establishment of Federal Supply Schedule Blanket Purchase Agreements
(BPAs) for recurring services is permitted when the procedures outlined herein
are followed.  All BPAs for services must define the services that may be
ordered under the BPA, along with delivery or performance time frames, billing
procedures, etc. The potential volume of orders under BPAs, regardless of the
size of individual orders, may offer the ordering office the opportunity to
secure volume discounts.  When establishing BPAs ordering offices shall

(i) Inform contractors in the request for quotation (based on the agency's
requirement) if a single BPA or multiple BPAs will be established, and indicate
the basis that will be used for selecting the contractors to be awarded the
BPAs.
    
(A) SINGLE BPA:  Generally, a single BPA should be established when the ordering
office can define the tasks to be ordered under the BPA and establish a
firm-fixed price or ceiling price for individual tasks or services to be
ordered. When this occurs, authorized users may place the order directly under
the established BPA when the need for service arises. The schedule contractor
that represents the best value and results in the lowest overall cost
alternative to meet the agency's needs should be awarded the BPA.     

(B) MULTIPLE BPAs:  When the ordering office determines multiple BPAs are needed
to meet its requirements, the ordering office should determine which contractors
can meet any technical qualifications before establishing the BPAs.  When
multiple BPAs are established, the authorized users must follow the procedure in
(3)(ii)(B) above, and then place the order with the schedule contractor that
represents the best value and results in the lowest overall cost alternative to
meet the agency's needs.

(ii) Review BPAs periodically.  Such reviews shall be conducted at least
annually.  The purpose of the review is to determine whether the BPA still
represents the best value (considering price, special qualifications, etc.) and
results in the lowest overall cost alternative to meet the agency's needs.

(5) The ordering office should give preference to small business concerns when
two or more contractors can provide the services at the same firm-fixed price or
ceiling price.
<PAGE>
 
Modification                                           Page 44 of 53 Pages


(6) When the ordering office's requirement involves both products as well as IT
professional services, the ordering office should total the prices for the
products and the firm-fixed price for the services and select the contractor
that represents the greatest value in terms of meeting the agency's total needs.

(7) The ordering office, at a minimum, should document orders by identifying the
contractor the services were purchased from, the services purchased, and the
amount paid. If other than a firm-fixed price order is placed, such
documentation should include the basis for the determination to use a labor-hour
or time-and-materials order. For agency requirements in excess of the
micro-purchase threshold, the order file should document the evaluation of
schedule contractors' proposals that formed the basis for the selection of the
contractor that received the order and the rationale for any trade-offs made in
making the selection.
    
b. Ordering Procedures for other services available on schedule at fixed prices
for specifically defined services or tasks.     

Orders placed pursuant to a Multiple Award Schedule (MAS), using the procedures
in FAR 8.404, are considered to be issued pursuant to full and open competition.
Therefore, when placing orders under Federal Supply Schedules, ordering offices
need not seek further competition, synopsize the requirement, make a separate
determination of fair and reasonable pricing, or consider small business set-
asides in accordance with subpart 19.5. GSA has already determined the prices of
items under schedule contracts to be fair and reasonable. By placing an order
against a schedule using the procedures outlined below, the ordering office has
concluded that the order represents the best value and results in the lowest
overall cost alternative (considering price, special features, administrative
costs, etc.) to meet the Government's needs.
    
(1) Orders placed at or below the micro-purchase threshold. Ordering offices can
place orders at or below the micro-purchase threshold with any Federal Supply
Schedule Contractor.       
    
(2) Orders excluding the micro-purchase threshold but not exceeding the maximum
order threshold.  Orders should be placed with the Schedule Contractor that can
provide the supply or service that represents the best value. Before placing an
order, ordering offices should consider reasonably available information
about the service offered under MAS contracts by using the "GSA Advantage!"
on-line shopping service, or by reviewing the, catalogs/pricelists of at
least three Schedule Contractors and selecting the delivery and other options
available under the      
<PAGE>
 
Modification                                           Page 45 of 53 Pages

    
schedule that meets the agency's needs.  In selecting the service representing
the best value, the ordering office may consider--(i) special features of the
service that are required in effective program performance and that are not
provided by a comparable service; and (ii) past performance.      

(3) Orders exceeding the maximum order threshold.  Each schedule contract has an
established maximum order threshold. This threshold represents the point where
it is advantageous for the ordering office to seek a price reduction.  In
addition to following the procedures in paragraph b, above, and before placing
an order that exceeds the maximum order threshold, ordering offices shall

(i) Review additional Schedule Contractors' catalogs/pricelists or use the "GSA
Advantage!" on-line shopping service;

(ii) Based upon the initial evaluation, generally seek price reductions from the
Schedule Contractor(s) appearing to provide the best value (considering price
and other factors); and

(iii) After price reductions have been sought, place

the order with the Schedule Contractor that provides the best value and results
in the lowest overall cost alternative.  If further price reductions are not
offered, an order may still be placed, if the ordering office determines that it
is appropriate.

NOTE:  For orders exceeding the maximum order threshold, the Contractor may:

(A) Offer a new lower price for this requirement (the Price Reductions clause is
not applicable to orders placed over the maximum order in FAR 52.216-19 Order
Limitations);

(B) Offer the lowest price available under the contract; or

(C) Decline the order (orders must be returned in accordance with
FAR 52.216-19).

(4) Blanket purchase agreements (BPAs). The establishment of Federal Supply
Schedule BPAs is permitted when following the ordering procedures in FAR 8.404.
All schedule contracts contain BPA provisions. Ordering offices may use BPAs to
establish accounts with Contractors to fill recurring requirements. BPAs should
address the frequency of ordering and invoicing, discounts, and delivery
locations and times.
<PAGE>
 
Modification                                           Page 46 of 53 Pages


(5) Price reductions.  In addition to the circumstances outlined in paragraph
(3), above, there may be instances when ordering offices will find it
advantageous to request a price reduction. For example, when the ordering office
finds a schedule service elsewhere at a lower price or when a BPA is being
established to fill recurring requirements, requesting a price reduction could
be advantageous. The potential volume of orders under these agreements,
regardless of the size of the individual order, may offer the ordering office
the opportunity to secure greater discounts. Schedule Contractors are not
required to pass on to all schedule users a price reduction extended only to an
individual agency for a specific order.

(6) Small business.  For orders exceeding the micro purchase threshold, ordering
offices should give preference to the items of small business concerns when two
or more items at the same delivered price will satisfy the requirement.

(7) Documentation.  Orders should be documented, at all, minimum, by identifying
the Contractor the item was purchased from, the item purchased, and the amount
paid. If an agency requirement in excess of the micro-purchase threshold is
defined so as to require a particular brand name, product, or feature of a
product peculiar to one manufacturer, thereby precluding consideration of a
product manufactured by another company, the ordering office shall include an
explanation in the file as to why the particular brand name, product, or feature
is essential to satisfy the agency's needs.

3. ORDER

a. Agencies may use written orders, EDI orders, blanket purchase agreements,
individual purchase orders, or task orders for ordering services under this
contract. Blanket Purchase Agreements shall not extend beyond the end of the
contract period; all services and delivery shall be made and the contract terms
and conditions shall continue in effect until the completion of the order.
Orders for tasks which extend beyond the fiscal year for which funds are
available shall include FAR 52.232-19 Availability of Funds for the Next Fiscal
Year. The purchase order shall specify the availability of funds and the period
for which funds are available.

b. All task orders are subject to the terms and conditions of the contract. In
the event of conflict between a task order and the contract, the contract will
take precedence.

experience, and expertise as stated in the task order.
    
d. Any Contractor travel required in the performance of IT/EC Services must
comply with the Federal Travel Regulation or Joint Travel Regulations, as
applicable, in effect on the date(s) the travel is performed.  Established
Federal Government per diem rates will apply to all Contractor travel.
Contractors cannot use GSA city pair contracts.      

5. INSPECTION OF SERVICE

The Inspection of Services-Fixed Price (AUG 1996) clause at FAR 52.246-4
applies to firm-fixed price orders placed under this contract. The
Inspection-Time-and-Materials and Labor-Hour (JAN 1986) clause at FAR 52.246-6
applies to time and materials and labor-hour orders placed under this contract.

6. RESPONSIBILITIES OF THE CONTRACTOR

The Contractor shall comply with all laws, ordinances, and regulations (Federal,
State, City, or otherwise) covering work of this character.

7. RESPONSIBILITIES OF THE GOVERNMENT

Subject to security regulations, the ordering office shall permit Contractor
access to all facilities necessary to perform the requisite IT/EC Services.
         
8.  INDEPENDENT CONTRACTOR

All IT/EC Services performed by the Contractor under the terms of this contract
shall be as an independent Contractor, and not as an agent or employee of the
Government.

9. ORGANIZATIONAL CONFLICTS OF INTEREST

a. Definitions.

"Contractor" means the person, firm, unincorporated association, joint venture,
partnership, or corporation that is a party to this contract.

"Contractor and its affiliates" and "Contractor or its affiliates" refers to the
Contractor, its chief executives, directors, officers, subsidiaries, affiliates,
subcontractors at any tier, and consultants and any joint venture involving the
Contractor, any entity into or with which the Contractor subsequently merges or
affiliates, or any other successor or assignee of the Contractor.

An "Organizational conflict of interest" exists when the nature of the work to
be performed under a proposed Government contract, without some restriction on
activities by the Contractor and its affiliates, may either (i) result in an
unfair competitive advantage to the Contractor or its affiliates or (ii) impair
the Contractor's or its affiliates' objectivity in performing contract work.

b. To avoid an organizational or financial conflict of interest and to avoid
prejudicing the best interests of the Government, ordering offices may place
restrictions on the Contractors, its affiliates, chief executives, directors,
subsidiaries and subcontractors at any tier when placing orders against schedule
contracts. Such restrictions shall be consistent with FAR 9.505 and shall be
designed to avoid, neutralize, or mitigate organizational conflicts of interest
that might otherwise exist in situations related to individual orders placed
against the schedule contract. Examples of situations, which may require
restrictions, are provided at FAR 9.508.

10. INVOICES

The Contractor, upon completion of the work ordered, shall submit invoices for
IT/EC services. Progress payments may be authorized by the ordering office on
individual orders if appropriate. Progress payments shall be based upon
completion of defined milestones or interim products. Invoices shall be
submitted monthly for recurring services performed during the preceding month.

For firm-fixed price orders the Government shall pay the Contractor, upon
submission of proper invoices or vouchers, the prices stipulated in this
contract for service rendered and accepted.  Progress payments shall be made
only when authorized by the order.  For time-and-materials orders, the Payments
under Time-and-Materials and Labor-Hour Contracts (Alternate I (APR 1984)) at
FAR 52.232-7 applies to time-and-materials orders placed under this contract.
For labor-hour orders, the Payment under Time-and-Materials and Labor-Hour
Contracts (FEB 1997) (Alternate II (JAN 1986)) at FAR 52.232-7 applies to
labor-hour orders placed under this contract.      

12. RESUMES

Resumes shall be provided to the GSA Contracting Officer or the user agency upon
request.

13. INCIDENTAL SUPPORT COSTS

Incidental support costs are available outside the scope of this contract. The
costs will be negotiated separately with the ordering agency in accordance with
the guidelines set forth in the FAR.

14. APPROVAL OF SUBCONTRACTS

The ordering activity may require that the Contractor receive, from the ordering
activity's Contracting Officer, written consent before placing any subcontract
for furnishing any of the work called for in a task order.

15. DESCRIPTION OF IT/EC SERVICES AND PRICING

                            DEED OF LEASE AGREEMENT

     THIS DEED OF LEASE AGREEMENT (hereinafter referred to as "Lease"), made
this 11th day of August 1998, by and between Massachusetts Mutual Life Insurance
Company, a corporation organized and existing under the laws of Maryland
(hereinafter referred to as the "Landlord") and Pulsar Data Systems, Inc., a
Corporation organized and existing under the laws of Maryland, (hereinafter
referred to as the "Tenant").

     WITNESSETH, THAT FOR AND IN CONSIDERATION of the mutual entry into this
Lease by the parties hereto, and for other good and valuable consideration, the
receipt and adequacy of which are hereby acknowledged by each party hereto, the
Landlord hereby leases to the Tenant and the Tenant hereby leases from the
Landlord all of that real property, situated and lying in Prince George's
County, Maryland, which consists of the space (containing 12,790 rentable square
feet of floor area) outlined in Exhibit A attached hereto and made a part hereof
(hereinafter referred to as the "Premises") and located in a building
(hereinafter referred to as the "Building") at 4390 Parliament Place, Lanham,
Maryland (the Premises, the remainder of the Building, such tract of land, other
buildings thereon, and any other buildings or improvements to be constructed
thereon being hereinafter referred to collectively as the "Property").

     SUBJECT TO THE OPERATION AND EFFECT of any and all instruments and matters
of record or in fact.

     UPON THE TERMS AND SUBJECT TO THE CONDITIONS which are hereinafter set
forth:

SECTION 1. TERM.
    
     1.1. LENGTH.  This Lease shall be for a term (hereinafter referred to as
the "Term") (a) commencing on the first day after the date on which the Landlord
substantially completes the improvements to be made to the Premises under the
provisions of Section 5 and tenders possession thereof to the Tenant (herein-
after referred to as the "Commencement Date", except that if the date of such
commencement is hereafter advanced or postponed by written agreement of the
parties hereto, the date to which it is advanced or postponed shall thereafter
be the "Commencement Date"), and (b) terminating at 12:01 A.M., local time, on
the fifth (5th) anniversary of the first (1st) day of the first (1st) full
calendar month during the Term (hereinafter referred to as the "Termination
Date", except that if the date of such termination is hereafter advanced or
postponed pursuant to any provision of this Lease, or by written agreement of
the parties hereto, the date to which it is advanced or postponed shall
thereafter be the Termination Date).     

     1.2.  Taking of possession by Tenant shall be deemed conclusively to
establish that said 

                                      -1-
<PAGE>
 
buildings and other improvements have been completed in accordance with the
plans and specifications and that the Premises are in good and satisfactory
condition, as of when possession was so taken. Tenant acknowledges that no
representations as to the repair of the Premises have been made by Landlord,
unless such are expressly set forth in this Lease. After such "Commencement
Date" Tenant shall, upon demand, execute and deliver to Landlord a letter of
acceptance of delivery of the Premises. In the event of any dispute as to
substantial completion or work performed or required to be performed by
Landlord, the certificate of Landlord's architect or general contractor shall be
conclusive.
    
     1.3. SURRENDER.  The Tenant shall at its expense, at the expiration of the
Term/1// or upon any earlier termination of this Lease, (a) promptly surrender
to the Landlord possession of the Premises (including any fixtures or other
improvements which, under the provisions of Section 5, are owned by the
Landlord) in good order and repair (ordinary wear and tear excepted) and broom
clean, (b) remove therefrom the Tenant's signs, goods and effects and any
machinery, trade fixtures and equipment used in conducting the Tenant's trade or
business and not owned by the Landlord, and (c) repair any damage to the
Premises or the Building caused by such removal.     

     1.4 HOLDING OVER.

            1.4.1. If the Tenant continues to occupy the Premises after the
expiration of the Term or any earlier termination of this Lease after obtaining
the Landlord's express, written consent thereto,

               (a) such occupancy shall (unless the parties hereto otherwise
agree in writing) be deemed to be under a month-to-month tenancy, which shall
continue until either party hereto notifies the other in writing, by at least
thirty (30) days before the end of any calendar month, that the notifying party
elects to terminate such tenancy at the end of such calendar month, in which
event such tenancy shall so terminate;

               (b) anything contained in the foregoing provisions of this
Section to the contrary notwithstanding, the rental payable for each such
monthly period shall equal one-twelfth (1/12) of the Base Rent and the
Additional Rent payable under the provisions of subsection 2.2 (calculated in
accordance with such provisions of subsection 2.2 as if this Lease had been
renewed for a period of twelve (12) full calendar months after such expiration
or earlier termination of the Term or such renewal); and

               (c) such month-to-month tenancy shall be upon the same terms and
subject to the same conditions as those set forth in the provisions of this
Lease; provided, that if the Landlord gives the Tenant, by at least thirty (30)
days before the end of any calendar month during such month-to-month tenancy,
written notice that such terms and conditions (including any thereof relating to
the amount or payment of Rent) shall, after such month, be modified in 

___________________
    
/1//  or any extension thereof     

                                      -2-
<PAGE>
 
any manner specified in such notice, then such tenancy shall, after such month,
be upon the said terms and subject to the said conditions, as so modified.
    
            1.4.2. If the Tenant continues to occupy the Premises after the
expiration of the Term or any earlier termination of this Lease without
obtaining the Landlord's express, written consent thereto, such occupancy shall
be on the same terms and subject to the same conditions as those set forth in
the provisions of paragraph 1.4.1, except that, anything contained in the
provisions of this Lease to the contrary notwithstanding, (a) the rental payable
during the period of such occupancy shall equal/2// of the rental which would be
payable during such period under the provisions of subparagraph 1.4.1.(b), had
the Tenant obtained the Landlord's express, written consent to such occupancy,
as aforesaid, and (b) nothing in the provisions of paragraph 1.4.1. or any other
provision of this Lease shall be deemed in any way to alter or impair the
Landlord's right immediately to evict the Tenant or exercise its other rights
and remedies under the provisions of this Lease or applicable law on account of
the Tenant's occupancy of the Premises without having obtained such 
consent.     

    
     

    
    
 
SECTION 2. RENT

provision of this Lease which accrues while this Lease is in effect.

          2. 1.3. Lease Year. As used in the provisions of this Lease, the term
"Lease Year" means (a) the period commencing on the Commencement Date and

     2.2. ANNUAL OPERATING COSTS/3//     
    
            2.2.1. Taxes.     

            (a) Tenant agrees to pay before they become delinquent all taxes,
assessments and governmental charges of any kind and nature whatsoever
(hereinafter referred to as "Taxes") lawfully levied or assessed against the
Building and the grounds, parking areas, driveways and alleys around the
Building. Tenant shall furnish to Landlord, not later than twenty (20) days
before the date any such Taxes become delinquent, official receipts of the
appropriate taxing authority or other evidence satisfactory to Landlord
evidencing payment thereof. If Tenant should fail to pay any Taxes, assessments
or governmental charges required to be paid by Tenant hereunder, in addition to
any other remedies provided herein, Landlord may, if it so elects, pay such
Taxes, assessments and governmental charges. Any sums so paid by Landlord shall
be deemed to be Additional Rent owing by Tenant to Landlord and due and payable
on demand by Landlord, together with interest thereon at the rate of twelve
percent (12%) per annum from the date paid by Landlord to the date of repayment
by Tenant.

            (b) In the event the Premises constitute a portion of a multiple
occupancy building, in lieu of Tenant paying the Taxes as provided above,
Landlord agrees to pay, before they become delinquent, all Taxes lawfully levied
or assessed against such Building and the grounds, parking areas, driveways and
alleys around the Building, and Tenant agrees to pay to Landlord, as Additional
Rent, upon demand, the amount of Tenant's proportionate share of such Taxes paid
by Landlord. Tenant's proportionate share means the percentage assigned to the
Premises for purposes of allocating Taxes as set forth herein and other Annual
Operating Costs as set forth in Subsection 2.2.2 below and represents the
approximate and (for purposes of this Lease) hereby agreed upon proportion which
the floor area of the Premises bears to the aggregate net rentable space within
the Building and the Property and shall be twenty two and 40/100 percent (22.40
%) of the Building and twenty two and 40/00 percent (22.40 % ) of the Property.

            2.2.2. Maintenance.

            (a) Maintenance by Tenant. Tenant shall, at its own cost and
expense, keep and maintain all parts of the Premises in good condition, promptly
making all necessary repairs and replacements, interior and non-structural,
ordinary and extraordinary, including but not limited to, glass and plate glass,
doors and office entry(s), walls and finish work, floors and floor covering,
heating and air conditioning systems, electrical systems, plumbing work and
fixtures, termite and pest extermination, regular removal of trash and debris.
The cost of maintenance and repair of any common party wall (any wall, divider,
partition or any other structure separating the premises from any adjacent
premises occupied by other tenants) shall be shared equally by 

___________________
    
/3//  In no event shall Tenant's annual increase in controllable Annual
Operating Costs (not including, real estate taxes, insurance, utilities and snow
removal) exceed six percent (6%) of the Tenant's previous years costs.     

                                      -4-
<PAGE>
 
Tenant and the tenant occupying adjacent premises. Tenant shall not damage any
party wall or disturb the integrity and support provided by any party wall and
shall, at its sole cost and expense, promptly repair any damage or injury to any
party wall caused by Tenant or its employees, agents or invitees.
    
          (b)  Maintenance by Landlord. Tenant and its employees, customers and
licensees shall have the non-exclusive right to use the parking areas, if any,
as may be designated by Landlord in writing, subject to such reasonable rules
and regulations as Landlord may from time to time prescribe. Further, in
multiple occupancy buildings, Landlord shall perform the roof, paving, and
landscape maintenance, exterior painting and common sewage line plumbing which
are otherwise Tenant's obligations under Subsection 2.2.2(a) above, and Tenant
shall, in lieu of the obligations set forth under Subsection 2.2.2(a) above with
respect to such items, be liable for its proportionate share (as defined in
Subsection 2.2.1(b) above) of the cost and expense of Building maintenance and
the care for the grounds around the Building, including but not limited to, the
mowing of grass, care of shrubs, general landscaping, maintenance of parking
areas, driveways and alleys, roof maintenance, exterior repainting and common
sewage line plumbing; provided, however, that Landlord shall have the right to
require Tenant to pay such other reasonable proportion of said mowing, shrub
care and general landscaping costs as may be determined by Landlord in its sole
discretion; and further provided that if Tenant or any other particular tenant
of the Building can be clearly identified as being responsible for obstruction
or stoppage of the common sanitary sewage line then Tenant, if Tenant is
responsible, or such other responsible tenant, shall pay the entire cost
thereof, upon demand, as additional rent. Tenant shall pay/4// when due its
share, determined as aforesaid, of such costs and expenses along with the other
tenants of the Building to Landlord upon demand, as Additional Rent, for the
amount of its share of such costs and expenses in the event Landlord elects to
perform or cause to be performed such work. Such share shall include a
management fee equal to five percent (5%) of the Rent for each Lease Year,
administrative and accounting costs, and a/5// reserve for asphalt, roof repairs
and repainting.    

          (c)  Maintenance Contract.  Tenant shall, at its own cost and expense,
enter into a regularly scheduled preventative maintenance/service contract with
a maintenance contractor for servicing all heating and air conditioning systems
and equipment within the Premises and shall provide Landlord with copies of all
service reports. The maintenance contractor and contract 

________________
    
/4//  within thirty (30) days     
    
/5//  reasonable     

                                      -5-
<PAGE>
 
    
must be approved by Landlord./6// The service contract must include all services
suggested by the equipment manufacturer within the operation/maintenance manual
and must become effective (and a copy thereof delivered to Landlord) within
thirty (30) days of the date Tenant takes possession of the Premises. Each Lease
year Landlord will inspect the HVAC system to determine that the aforementioned
maintenance is being performed. If the HVAC system is not being maintained
pursuant to this Section Landlord will send notice of such lack of maintenance
to Tenant and Tenant shall thereafter have thirty (30) days to perform the
necessary maintenance. Failure by Tenant to complete the necessary maintenance
in such thirty (30) day period shall be a material Event of Default and Landlord
shall have the right to cure such Event of Default pursuant to Section 13.
Should the inspection demonstrate a lack of maintenance of the HVAC system,
Tenant shall pay for the cost of such inspection. Thirty days before Tenant
vacates the Premises, Landlord will have the HVAC equipment inspected by a
qualified HVAC mechanic at Landlord's expense. If in the opinion of the HVAC
mechanic, the equipment has not been properly maintained,/7// then Landlord may
authorize necessary repairs to be made to the system. Such repairs will be
deducted from the Tenant's security deposit. Tenant shall reimburse Landlord for
any and all costs associated with such repairs which exceed the amount of any
security deposit. The remainder of the security deposit, if any, shall be
refunded to Tenant in accordance with the terms of the Lease.    

            2.2.3. Computation. After the end of each calendar year during the
Term, the Landlord shall compute the total of the Annual Operating Costs
incurred for all of the Property during such calendar year, and shall allocate
them to the net rentable space within the Property in proportion to the
respective operating costs percentages assigned to such spaces; provided, that
anything contained in the foregoing provisions of this subsection 2.2 to the
contrary notwithstanding, wherever the Tenant and/or any other tenant of space
within the Property has agreed in its lease or otherwise to provide any item of
such services partially or entirely at its own expense, or wherever in the
Landlord's judgment any such significant item of expense is not incurred with
respect to or for the benefit of all of the net rentable space within the
Property, in allocating the Annual Operating Costs pursuant to the foregoing
provisions of this subsection the Landlord shall make an appropriate adjustment,
using generally accepted accounting principles, as aforesaid, so as to avoid
allocating to the Tenant or to such other tenant (as the case may be) those
Annual Operating Costs covering such services already being provided by the
Tenant or by such other tenant at its own expense, or to avoid allocating to all
of the net rentable space within the Property those Annual Operating Costs
incurred only with respect to a portion thereof, as aforesaid.

            2.2.4. Payment as Additional Rent. The Tenant shall, within fifteen
(15) days after demand therefor by the Landlord (with respect to each calendar
year during the Term), accompanied by a statement setting forth in reasonable
detail the Annual Operating Costs for 


____________________
    
/6//   , which approval shall not be unreasonably withheld, conditioned or 
       delayed     
    
/7//   , reasonable wear and tear excepted     

                                      -6-
<PAGE>
 
such calendar year, pay to the Landlord as Additional Rent the amount of the
Tenant's operating costs percentage of the Annual Operating Costs for such
calendar year (as derived and allocated under the provisions of paragraph
2.2.3).

            2.2.5. Proration. If only part of any calendar year falls within the
Term, the amount computed as Additional Rent for such calendar year under the
foregoing provisions of this subsection shall be prorated in proportion to the
portion of such calendar year falling within the Term (but the expiration of the
Term before the end of a calendar year shall not impair the Tenant's obligation
hereunder to pay such prorated portion of such Additional Rent for that portion
of such calendar year falling within the Term, which shall be paid on demand, as
aforesaid).
    
            2.2.6. Landlord's right to estimate. Anything contained in the
foregoing provisions of this subsection to the contrary notwithstanding, the
Landlord may, at its discretion, (a) make from time to time during the Term a
reasonable estimate of the Additional Rent which may become due under such
provisions for any calendar year, (b) require the Tenant to pay to the Landlord
for each calendar month during such year one twelfth (1/12) of such Additional
Rent, at the time and in the manner that the Tenant is required hereunder to pay
the monthly installment of the Base Rent for such month, and (c) at the
Landlord's reasonable discretion, increase or decrease from time to time during
such calendar year the amount initially so estimated for such calendar year, all
by giving the Tenant written notice thereof, accompanied by a schedule setting
forth in reasonable detail the expenses comprising the Annual Operating Costs,
as so estimated. In such event, the Landlord shall cause the actual amount of
such Additional Rent to be computed and certified to the Tenant within 120 days
after the end of such calendar year, and the Tenant or the Landlord, as the case
may be, shall promptly thereafter pay to the other the amount of any deficiency
or overpayment therein, as the case may be./8//     

____________________________
    
/8//  Right to Audit:     

      (a)  Selection of Accountants: If Tenant disputes the amount of an
           adjustment or the proposed estimated increase or decrease in Taxes or
           Annual Operating Costs, Tenant shall give Landlord written notice of
           such dispute within thirty (30) days after Landlord advises Tenant of
           such adjustment or proposed increase or decrease. Tenant's failure to
           give such notice shall waive its right to dispute the amounts so
           determined. Tenant shall also not be entitled to dispute the
           foregoing amounts if Tenant is then in default hereunder. If Tenant
           is entitled to and timely objects, Tenant shall have the right to
           engage its own accountants ("Tenants Accountants") for the purposes
           of verifying the accuracy of the statement in dispute, or the
           reasonableness of the adjustment or estimated increase or decrease.
           If Tenant's Accountants determine that an error has been made,
           Landlord and Tenant's Accountants shall endeavor to agree upon the
           matter. If they cannot agree within twenty (20) days from the date
           Tenant's Accountants commence reviewing Landlord's records, Landlord
           and Tenant's Accountants shall jointly 

                                      -7-
<PAGE>
 
     2.3. WHEN DUE AND PAYABLE.

            2.3.1. The Base Rent for any Lease Year shall be due and payable in
twelve (12) consecutive, equal monthly installments, in advance, on the first
(lst) day of each calendar month during such Lease Year; provided, that the
first monthly installment of the Base Rent will be due and payable upon lease
execution.
    
            2.3.2. Any Additional Rent, other than Annual Operating Costs which
are due and payable with each payment of Base Rent, accruing to the Landlord
under any provision      

______________________

           select an independent certified public accounting firm (the
           "Independent Accountant") which firm shall conclusively determine
           whether the adjustment or estimated increase or decreases is
           reasonable, and if not, what amount is reasonable. Both parties shall
           be bound by such determination. If Tenant's Accountants do not
           participate in choosing the Independent Accountant within 20 days
           from the date Landlord and Tenant's Accountant's determine that they
           cannot agree as to whether or not an error has been made, then
           Landlord's determination of the adjustment or estimated increase or
           decrease shall be conclusively determined to be reasonable and Tenant
           shall be bound hereby.

      (b)  Payment of Costs: All costs incurred by Tenant in obtaining Tenant's
           Accountants and the cost of the Independent Accountant shall be paid
           by Tenant unless Tenant's Accountants disclose an error, acknowledge
           by Landlord (or found to have conclusively occurred by the
           Independent Accountant), of more than ten percent (10%) in the
           computation of the total amount of Taxes or Annual Operating Costs as
           set forth in the statement submitted by Landlord with respect to the
           matter in dispute; in which event Landlord shall pay the reasonable
           costs incurred by Tenant in obtaining such audits. No subtenant shall
           have the right to conduct an audit and no assignee shall conduct an
           audit for any period during which such assignee was not in possession
           of the Premises.

      (c)  Continuation of Payments Pending Determination: Tenant shall continue
           to timely pay Landlord the amount of the prior year's adjustment and
           adjusted Additional Rent determined to be incorrect as aforesaid
           until the parties have concurred as to the appropriate adjustment or
           have deemed to be bound by the determination of the Independent
           Accountant in accordance with the preceding terms. Landlord's delay
           in submitting any statement contemplated herein for any Lease Year
           shall not affect the provisions of this Paragraph, nor constitute a
           waiver of Landlord's rights as set forth herein for said Lease Year
           or any subsequent Lease Years during the Lease Term or any extensions
           thereof.

                                      -8-
<PAGE>
 
    
of this Lease shall, except as is otherwise set forth herein, be due 
and/9//     
    
            2.3.3.  Each such payment shall be made promptly when due, without
any deduction or setoff whatsoever, and without demand, failing which the Tenant
shall pay to the Landlord as Additional Rent, a late charge equaling/10// of
the sum of the Base Rent and Additional Rent outstanding.     

     2.4. WHERE PAYABLE.  The Tenant shall pay the Rent, in lawful currency of
the United States of America, to the Landlord by delivering or mailing it
(postage prepaid) to the Landlord's address which is set forth in Section 16, or
to such other address or in such other manner as the Landlord from time to time
specifies by written notice to the Tenant. Any payment made by the Tenant to the
Landlord on account of Rent may be credited by the Landlord to the payment of
any Rent then past due, including late fees, interest and penalties, before
being credited to Rent currently falling due. Any such payment which is less
than the amount of Rent then due shall constitute a payment made on account
thereof, the parties hereto hereby agreeing that the Landlord's acceptance of
such payment (whether or not with or accompanied by an endorsement or statement
that such lesser amount or the Landlord's acceptance thereof constitutes payment
in full of the amount of Rent then due) shall not alter or impair the Landlord's
rights hereunder to be paid all of such amount then due, or in any other
respect.

     2.5. TAX ON LEASE.  If federal, state or local law now or hereafter imposes
any tax, assessment, levy or other charge (other than any income, inheritance or
estate tax) directly or indirectly upon (a) the Landlord with respect to this
Lease or the value thereof, (b) the Tenant's use or occupancy of the Premises,
(c) the Base Rent, Additional Rent or any other sum payable under this Lease, or
(d) this transaction, then (except if and to the extent that such tax,
assessment, levy or other charge is included in the Annual Operating Costs) the
Tenant shall pay the amount thereof as Additional Rent to the Landlord upon
demand, unless the Tenant is prohibited by law from doing so, in which event the
Landlord may, at its election, terminate this Lease by giving written notice
thereof to the Tenant.

     2.6. SECURITY DEPOSIT.

            2.6.1. Simultaneously with the entry into this Lease by the parties
hereto, the Tenant shall deposit with the Landlord the sum of twenty-six
thousand two hundred nineteen and 50/100 Dollars ($26,219.50), which shall be

Lease./11//     

            2.6.2. On the occurrence of an Event of Default, the Landlord shall
be entitled, at its sole discretion,

                    (a) to apply any or all of such sum in payment of (i) any
Rent then due and unpaid, (ii) any expense incurred by the Landlord in curing
any such event of default, and/or (iii) any damages incurred by the Landlord by
reason of such event of default (including, by way of example rather than of
limitation, that of reasonable attorneys' fees); and/or

                    (b) to retain any or all of such sum to reimburse for any or
all damages suffered by the Landlord by reason of event of such default. If at
any time Landlord draws upon the security deposit in accordance with this
section Tenant upon demand agrees to immediately pay to Landlord an amount
sufficient to return the security deposit to the amount stated above.
    
            2.6.3. On the termination of this Lease, any of such sum which is
not so applied or retained shall be returned to the Tenant within/12// of the
Lease termination date.     

            2.6.4. Such sum shall not bear interest while being held by the
Landlord hereunder.

            2.6.5. No Mortgagee (as that term is defined by the provisions of
Section 12) or purchaser of any or all of the Property at any foreclosure
proceeding brought under the provisions of any Mortgage (as that term is defined
by the provisions of Section 12) shall (regardless of whether the Lease is at
the time in question subordinate to the lien of any Mortgage under the
provisions of Section 12 or otherwise) be liable to the Tenant or any other
person for any or all of such sum (or any other or additional security deposit
or other payment made by the Tenant under the provisions of this Lease), unless
both (a) the Landlord has actually delivered it in cash to such Mortgagee or
purchaser, as the case may be, and (b) it has been specifically identified, and
accepted by the Lender or such purchaser, as the case may be, as such and for
such purpose, then Landlord will have no further liability for return of the
security deposit.

SECTION 3. USE OF PREMISES.

     3.1  The Tenant shall, continuously throughout the Term occupy and use the
Premises for and only for general office and warehouse purposes.

Tenant shall not violate any applicable law, ordinance or regulation.

     3.3  License.

             3.3.1 The Landlord hereby grants to the Tenant a non-exclusive
license to use (and to permit its officers, directors, agents, employees and
invitees to use in the course of conducting business at the Premises), 

             (a) any and all portions of the said tract of land on which the
Building is located (excluding that portion thereof which is improved by any
other building) which, by their nature, are manifestly designed and intended for
common use by the occupants of the Building and of any other improvements on
such tract, for pedestrian ingress and egress to and from the Premises and for
any other such manifest purposes; and

             (b) any and all portions of such tract of land as from time to time
are designated (by striping or otherwise) by the Landlord for such purpose, for
the parking of automobiles.

             3.3.2. Such license shall be exercised in common with the exercise
thereof by the Landlord, any tenant or owner of the building or any other
building located on such tract, and their respective officers, directors,
agents, employees and invitees, and in accordance with the Rules and Regulations
promulgated from time to time pursuant to the provisions of Section 11.

     3.4  SIGNS.  The Tenant shall have the right to erect from time to time
within the Premises such signs as it desires, in accordance with applicable law,
except that the Tenant shall not erect any sign within the Premises in any place

Landlord has given its express, written consent thereto.

SECTION 4. INSURANCE AND INDEMNIFICATION.

     4.1  INCREASE IN RISK. The Tenant

             4.1.1. shall not do or permit to be done any act or thing as a
result of which either (a) any policy of insurance of any kind covering (i) any
or all of the Property or (ii) any liability of the Landlord in connection
therewith may become void or suspended, or (b) the insurance risk under any such
policy would (in the opinion of the insurer thereunder) be made greater; and

             4.1.2. shall pay as Additional Rent the amount of any increase in
any premium for such insurance resulting from any breach of such covenant.

     4.2  INSURANCE TO BE MAINTAINED BY TENANT.

                                      -11-
<PAGE>
 
             4.2.1. The Tenant shall maintain at its expense, throughout the
Term, insurance against loss or liability in connection with bodily injury,
death, property damage or destruction, occurring within the Premises or arising
out of the use thereof by the Tenant or its agents, employees, officers or
invitees, visitors and guests, under one or more policies of general public
liability insurance having such limits as to each as are reasonably required by
the Landlord from time to time, but in any event of not less than a total of Two
Million Dollars ($2,000,000.00) for bodily injury to or death of all persons or
property damage or destruction in any one occurrence, and (b) Fifty Thousand
Dollars ($50,000.00) Fire Legal Liability. Each such policy shall (a) name as
the insured thereunder the Tenant and the Landlord (and, at the Landlord's
request, any Mortgagee) as additional insureds, (b) by its terms, not be
cancellable without at least thirty (30) days' prior written notice to the
Landlord (and, at the Landlord's request, any such Mortgagee), and (c) be issued
by any insurer of recognized responsibility licensed to issue such policy in the
State of Maryland.

             4.2.2. (a) At least five (5) days before the Commencement Date, the
Tenant shall deliver to the Landlord a certificate of each such policy, and (b)
at least thirty (30) days before any such policy expires, the Tenant shall
deliver to the Landlord an original or a signed duplicate copy of a replacement
policy therefor; provided, that so long as such insurance is otherwise in
accordance with the provisions of this Section, the Tenant may carry any such
insurance under a blanket policy covering the Premises for the risks and in the
minimum amounts specified in paragraph 4.2.1, in which event the Tenant shall
deliver to the Landlord two (2) insurer's certificates therefor in lieu of an
original or a copy thereof, as aforesaid.

     4.3  INSURANCE TO BE MAINTAINED BY LANDLORD. The Landlord shall maintain
throughout the Term all-risk insurance upon the Building, including as needed
but not limited to Personal Property, Loss of Rents, Glass, Boiler and
Machinery, General Liability and Umbrella Liability in at least such amounts and
having at least such forms of coverage as are required from time to time by the
Landlord's lender. The cost of the premiums for such insurance and of each
endorsement thereto and of any applicable deductibles therefor shall be deemed,
for purposes of the provisions of Section 2, to be a cost of operating and
maintaining the Property.

     4.4  WAIVER OF SUBROGATION. If either party hereto is paid any proceeds
under any policy of insurance naming such party as an insured, on account of any
loss, damage or liability, then such party hereby releases the other patty
hereto, to and only to the extent of the amount of such proceeds, from any and
all liability for such loss, damage or liability, notwithstanding that such
loss, damage or liability may arise out of the negligent or intentionally
tortious act or omission of the other party, its agents or employees; provided,
that such release shall be effective only as to a loss, damage or liability
occurring while the appropriate policy of insurance of the releasing party
provides that such release shall not impair the effectiveness of such policy or
the insured's ability to recover thereunder. Each party hereto shall use
reasonable efforts to have a clause to such effect included in its said
policies, and shall promptly notify the other in writing if such clause cannot
be included in any such policy.

                                      -12-

     4.5  LIABILITY OF PARTIES. Except if and to the extent that such party is
released from liability to the other party hereto pursuant to the provision of
subsection 4.4.

             4.5.1. the Landlord (a) shall be responsible for, and shall
indemnify and hold harmless the Tenant against and from any and all liability
arising out of, any injury to or death of any person or damage to any property,
occurring anywhere upon the Property, if, only if and to the extent that such
injury, death or damage is proximately caused by the grossly negligent or
intentionally tortious act or omission of the Landlord or its agents, officers
or employees, but (b) shall not be responsible for or be obligated to indemnify
or hold harmless the Tenant against or from any liability for any such injury,
death or damage occurring anywhere upon the Property (including the Premises),
(i) by reason of the Tenant's occupancy or use of the Premises or any other
portion of the Property, or (ii) because of fire, windstorm, act of God or other
cause unless solely caused by such gross negligence or intentionally tortious
act or omission of the Landlord, as aforesaid; and

             4.5.2. subject to the operation and effect of the foregoing
provisions of this subsection, the Tenant shall be responsible for, and shall
defend, indemnify and hold harmless the Landlord against and from, any and all
liability or claim of liability (including without limitation reasonable
attorney's fees) arising out of any injury to or death of any person or damage
to any property, occurring within the Premises, or, if caused by Tenant, its
employees, agents or invitees, on the Property.

SECTION 5. IMPROVEMENTS TO PREMISES.
    
     5.1  BY LANDLORD./13//     
    
             5.1.1. The Landlord/14// shall make the improvements to the
Premises which are set forth in the plans and specifications attached hereto as
Exhibit B-1.     

_____________________
    
/13//  Landlord shall provide a turn key buildout based upon the final approved
space plan dated July 24,1998 and attached hereto in Exhibit B-1. The cost of
any additional improvements or services incurred due to Tenant's modification of
the final approved space plan shall be promptly paid directly by Tenant to
Landlord upon written request by Landlord (to include invoice with back-up), and
failure to pay such sum in accordance with the schedule below shall constitute
an Event of Default under the Lease. Landlord's contractor shall perform all
work to be done within the Premises, with the exception of Tenant's telephone
and data cabling.    

In the event the cost of the improvement exceeds the Allowance, Tenant shall
repay such costs in accordance with the following schedule; (a) seventy five
percent (75%) upon requisition of the improvements and (b) twenty five percent
(25%) upon the substantial completion of the improvements.
    
/14//  at its sole cost and expense

<PAGE>
 
             5.1.2. [Deleted]
    
             5.1.3. the Landlord shall use reasonable efforts to complete such
improvements by the date on which the Tenant is entitled to occupy the Premises
pursuant to this Lease, but shall have no liability to the Tenant hereunder if
prevented from doing so by reason of any (a) strike, lock-out or other labor
troubles, (b) governmental restrictions or limitations, (c) failure or shortage
of electrical power, gas, water, fuel oil, or other utility or service, (d)
riot, war, insurrection or other national or local emergency (e) accident,
flood, fire or other casualty, (f) adverse weather condition, (g) other act of
God, (h) inability to obtain a certificate of occupancy, or (i) shortage of
materials or labor, or (j) other cause similar or dissimilar to any of the
foregoing and beyond the Landlord's reasonable control. In such event, (a) the
Commencement Date shall be postponed for a period equalling the length of such
delay, (b) the Termination Date shall be determined pursuant to the provisions
of subsection 1.1 by reference to the Commencement Date as so postponed, and (c)
the Tenant shall accept possession of the Premises within three (3) days after
such completion. If Tenant does not submit drawings or approvals in a timely
manner and, as a result, the Landlord cannot deliver the Premises timely, the
Lease Commencement Date shall not be postponed.     

     5.2  BY TENANT.  The Tenant shall not make any alteration, addition or
improvement to the Premises without first obtaining the Landlord's written
consent thereto.

     If the Landlord consents to any such proposed alteration, addition or
improvement, it shall be made at the Tenant's sole expense (and the Tenant shall
hold the Landlord harmless from any cost incurred on account thereof), and at
such time and in such manner as not unreasonably to interfere with the use and
enjoyment of the remainder of the Property by any tenant thereof or other
person.

     5.3  MECHANICS' LIEN. The Tenant shall (a) immediately after it is filed or
claimed, bond or have released any mechanics', materialman's or other lien filed
or claimed against any or all of the Premises, the Property, or any other
property owned or leased by the Landlord, by reason of labor or materials
provided for the Tenant or any of its contractors or subcontractors (other than
labor or materials provided by the Landlord pursuant to the provisions of
subsection 5.1), or otherwise arising out of the Tenant's use or occupancy of
the Premises or any other portion of the Property, and (b) defend, indemnify and
hold harmless the Landlord against and from any and all liability, claim of
liability or expense (including, by way of example rather than of limitation,
that of reasonable attorneys' fees) incurred by the Landlord on account of any
such lien or claim.

     5.4  FIXTURES. Any and all improvements, repairs, alterations and all other
property attached to, used in connection with or otherwise installed within the
Premises by the Landlord or the Tenant shall, immediately on the completion of
their installation, become the Landlord's property without payment therefor by
the Landlord, except that any machinery, equipment or fixtures installed by the
Tenant and used in the conduct of the Tenant's trade or business (rather than to
service the Premises or any of the remainder of the Building or the Property
generally) 

                                      -14-
<PAGE>
 
shall remain the Tenant's property.

SECTION 6. UTILITIES AND SERVICES.

     6.1 UTILITIES. Landlord agrees to provide at its cost water and electricity
service connections into the Premises and telephone service connections to the
Building, but Tenant shall pay for all water, gas, heat, light, power,
telephone, sewer, sprinkler charges, meter installation charges, and other
utilities and services used on or from the Premises, together with any taxes,
penalties, surcharges or the like pertaining thereto and any maintenance charges
for utilities and shall furnish all electric light bulbs and tubes. If any such
services are not separately metered to Tenant, Tenant shall pay its
proportionate share as determined by Landlord of all charges jointly metered
within the Building.
    
     6.2 INTERRUPTION. The Landlord shall have no liability to the Tenant for
any compensation or reduction of rent on account of any failure, modification or
interruption of any such service which either (a) arises out of any of the
causes enumerated in the provisions of subsection 5.1.3, or (b) is required by
applicable law (including, by way of example rather than of limitation, any
federal law or regulation relating to the furnishing or consumption of energy or
the temperature of buildings).     

SECTION 7. LANDLORD'S RIGHT OF ENTRY.
    
     The Landlord and its agents shall be entitled to enter the Premises at any
reasonable time (a) to inspect the Premises, (b) to exhibit the Premises to any
existing or prospective purchaser, tenant/15// or Mortgagee thereof, (c) to make
any alteration, improvement or repair to the Building or the Premises, or (d)
for any other purpose relating to the operation or maintenance of the Property;
provided that the Landlord shall (a) (unless doing so is impractical or
unreasonable because of emergency) give the Tenant at least twenty-four (24)
hours' prior notice of its intention to enter the Premises, and (b) use
reasonable efforts to avoid thereby interfering more than is reasonably
necessary with the Tenant's use and enjoyment thereof.     

SECTION 8. FIRE AND OTHER CASUALTIES.

     8.1 GENERAL. If the Premises are damaged by fire or other casualty during
the term,
    
            8.1.1. the Landlord shall, with reasonable promptness (taking into
account the time required by the Landlord to effect a settlement with, and to
procure any insurance proceeds from, any insurer against such casualty, but in
any event within/16// days after the date of such casualty), substantially
restore the premises to their condition immediately before such casualty,

and may temporarily enter and possess any or all of the Premises for such
purpose (provided, that the Landlord shall not be obligated to repair, restore
or replace any fixture, improvement, alteration, furniture, or other property
owned, installed or made by the Tenant), but
    
            8.1.2. the times for commencement and completion of any such
restoration shall be extended for the period of any delay occasioned by the
Landlord in doing so arising out of any of the causes enumerated in the
provisions of subsection 5.1. If the Landlord undertakes to restore the Premises
and such restoration is not accomplished within the said period of/17// days
plus the period of any extension thereof, as aforesaid, the Tenant may terminate
this Lease by giving written notice thereof to the Landlord within thirty (30)
days after the expiration of such period, as so extended; and     
    
            8.1.3. so long as the Tenant is deprived of the use of any or all of
the Premises on account of such casualty, the Base Rent and any Additional Rent
payable under the provisions of subsection 2.2 shall be abated in proportion to
the number of square feet of the Premises rendered substantially unfit for
occupancy by such casualty, unless, because of any such damage, the undamaged
portion of the Premises is made materially unsuitable for use by the Tenant for
the purposes set forth in the provisions of Section 3, in which event the Base
Rent and any such Additional Rent shall be abated entirely during such period of
deprivation.     

     8.2 SUBSTANTIAL DESTRUCTION. Anything contained in the foregoing provisions
of this Section to the contrary notwithstanding,

            8.2.1. if during the Term the Building is so damaged by fire or
other casualty that (a) either the Premises or (whether or not the Premises are
damaged) the Building is rendered substantially unfit for occupancy, as
reasonably determined by the Landlord, or (b) the Building is damaged to the
extent that the Landlord reasonably elects to demolish the Building, or if any
Mortgagee requires that any or all of such insurance proceeds be used to retire
any or all of the debt secured by its Mortgage, then in any such case the
Landlord may elect to terminate this Lease, as of the date of such casualty by
giving written notice thereof to the Tenant within thirty (30) days after the
date of such casualty; and

            8.2.2. in such event, (a) the Tenant shall pay to the Landlord the
Base Rent and any Additional Rent payable by the Tenant hereunder and accrued
through the date of such termination, (b) the Landlord shall repay to the Tenant
any and all prepaid Rent for periods beyond such termination, and (c) the
Landlord may enter upon and repossess the Premises without further notice.

     8.3 TENANT'S NEGLIGENCE. Anything contained in any provision of this Lease
to the contrary notwithstanding, if any such damage to the Premises, the
Building or both are caused by or result from the negligent or intentionally
tortious act or omission of the Tenant, those claiming

under the Tenant or any of their respective officers, employees, agents or
invitees,

            8.3.1. the Rent shall not be suspended or apportioned as aforesaid,
and

            8.3.2. except if and to the extent that the Tenant is released from
liability therefor pursuant to the provisions of subsection 4.4, the Tenant
shall pay to the Landlord upon demand, as Additional Rent, the cost of (a) any
repairs and restoration made or to be made as a result of such damage, or (b)
(if the Landlord elects not to restore the Building) any damage or loss which
the Landlord incurs as a result of such damage.

SECTION 9. CONDEMNATION.

     9.1 RIGHT TO AWARD.

            9.1.1. If any or all of the Premises are taken by the exercise of
any power of eminent domain or are conveyed to or at the direction of any
governmental entity under a threat of any such taking (each of which is
hereinafter referred to as a "Condemnation"), the Landlord shall be entitled to
collect from the condemning authority thereunder the entire amount of any award
made in any such proceeding or as consideration for such conveyance, without
deduction therefrom for any leasehold or other estate held by the Tenant under
this Lease.
    
            9.1.2. The Tenant hereby (a) assigns to the Landlord all of the
Tenant's right, title and interest, if any, in and to any such award; (b) waives
any right which it may otherwise have in connection with such Condemnation,
against the Landlord or such condemning authority, to any payment for (i) the
value of the then-unexpired portion of the Term, (ii) leasehold damages, and
(iii) any damage to or diminution of the value of the Tenant's leasehold
interest hereunder or any portion of the Premises not covered by such
Condemnation; and (c) agrees to execute any and all further documents which may
be required to facilitate the Landlord's collection of any and all such 
awards.     
    
            9.1.3. Subject to the operation and effect of the foregoing
provisions of this Section, the Tenant may seek, in a separate proceeding, a
separate award on account of any damages or costs incurred by the Tenant as a
result of such Condemnation, so long as such separate award in no way diminishes
any award or payment which the Landlord would otherwise receive as a result of
such Condemnation and Tenants right of recovery is limited to moving expenses
and the cost of trade fixtures.     

     9.2 EFFECT OF CONDEMNATION.

            9.2.1. If (a) all of the Premises are covered by a Condemnation, or
(b) any part of the Premises is covered by a Condemnation and the remainder
thereof is insufficient for the reasonable operation therein of the Tenant's
business, or (c) any of the Building is covered by a Condemnation and, in the
Landlord's reasonable opinion, it would be impractical to restore the 

                                      -17-
<PAGE>
 
remainder thereof, or (d) any of the rest of the Property is covered by a
Condemnation and, in the Landlord's reasonable opinion, it would be impractical
to continue to operate the remainder of the Property thereafter, then, in any
such event, the Term shall terminate on the date on which possession of so much
of the Premises, the Building or the rest of the Property, as the case may be,
as is covered by such Condemnation is taken by the condemning authority
thereunder, and all Rent (including, by way of example rather than of
limitation, any Additional Rent payable under the provision of subsection 2.2),
taxes and other charges payable hereunder shall be apportioned and paid to such
date.

            9.2.2. If there is a Condemnation and the Term does not terminate
pursuant to the foregoing provision of this subsection, the operation and effect
of this Lease shall be unaffected by such Condemnation, except that the Base
Rent shall be reduced in proportion to the square footage of floor area, if any,
of the Premises covered by such Condemnation.

     9.3 If there is a Condemnation, the Landlord shall have no liability to the
Tenant on account of any (a) interruption of the Tenant's business upon the
Premises, (b) diminution in the Tenant's ability to use the Premises, or (c)
other injury or damage sustained by the Tenant as a result of such Condemnation.

     9.4 Except for any separate proceeding brought by the Tenant under the
provisions of paragraph 9.1.3., the Landlord shall be entitled to conduct any
such condemnation proceeding and any settlement thereof free of interference
from the Tenant, and the Tenant hereby waives any right which it otherwise has
to participate therein.

SECTION 10.  ASSIGNMENT AND SUBLETTING.
    
     10.1 The Tenant hereby acknowledges that the Landlord has entered into this
Lease because of the Tenant's financial strength, goodwill, ability and
expertise and that, accordingly, this Lease is one which is personal to the
Tenant, and agrees for itself and its successors and assigns in interest
hereunder that it will not (a) assign any of its rights under this Lease, or (b)
make or permit any total or partial sale, lease, sublease, assignment,
conveyance, license, mortgage, pledge, encumbrance, or a transfer of a
controlling interest in Tenant, or other transfer of any or all of the Premises
or the occupancy or use thereof (each of which is hereinafter referred to as a
"Transfer"), without first obtaining the Landlord's written consent thereto
(which consent/18// and, if given, shall not constitute a consent to any
subsequent such Transfer, whether      

____________________
    
/18//  shall not be unreasonably withheld, conditioned or delayed, so long as
such transferee meets Landlord's reasonable criteria, which criteria are as
follows:     

       a.  The financial strength of the proposed assignee or subtenant, both in
           terms of net worth and in terms of reasonably anticipated cash flow
           over the Lease term, is not materially less than Tenant's financial
           strength at the time this Lease was signed or at the time of such
           assignment or sublease, whichever is greater.

                                      -18-
<PAGE>
 
    
by the person hereinabove named as the "Tenant" or by any such transferee). The
Landlord shall be entitled, at its sole discretion, to condition any such
consent upon the entry by such person into an agreement with (and in form and
substance satisfactory to) the Landlord, by which it assumes all of the Tenant's
obligations hereunder. Any person to whom any Transfer is attempted without such
consent shall have no claim, right or remedy whatsoever hereunder against the
Landlord, and the Landlord shall have no duty to recognize any person claiming
under or through the same. No such action taken with or without the Landlord's
consent shall in any way relieve or release the Tenant from liability for the
timely performance of all of the Tenant's obligations hereunder. The Tenant
hereby acknowledges that any merger, consolidation or other restructuring of
ownership interests in Tenant constitutes a Transfer hereunder. As additional
rent, Tenant shall reimburse Landlord promptly for reasonable legal and other
expenses incurred by Landlord in connection with any request by Tenant for
consent to assignment or subletting; no assignment or subletting shall affect
the continuing primary liability of Tenant (which, following assignment, shall
be joint and several with the assignee); no consent to any of the foregoing in a
specific instance shall operate as a waiver in any subsequent instance. In the
event that any assignee or subtenant pays to Tenant any amounts in excess of the
Annual Rent and additional rent then payable hereunder, or pro rata portion
thereof on a square footage basis for any portion of the Premises, Tenant shall
promptly pay/19// said excess to Landlord as and when received by Tenant.

contrary

     b.    The proposed assignee or subtenant will not burden the Premises
           and/or Common Areas to an extent substantially disproportionate to
           typical tenants of the Building, whether through disproportionate
           demand for landlord services or utilities, disproportionate bearing
           weights on floor areas, disproportionate parking requirements,
           deterioration of floors or other elements of the Building, or
           otherwise.

     c.    The proposed assignee or subtenant does not intend to make
           substantial alterations to the Premises which would, in Landlord's
           reasonable judgement, result in a material net decrease in the value
           of the Premises as improved.

     d.    The proposed assignee's or subtenant's use of the Premises will, in
           Landlord's sole judgment, be compatible with the uses of the other
           tenants in the Building or will be appropriate for a Class A office
           building.

     e.    Any other basis on which Landlord can reasonably refuse to withhold
           its consent to the proposed assignment or sublease, including any
           failure of the proposed assignee or subtenant to meet any of the
           reasonable criteria of Landlord that Tenant was required to meet
           prior to the execution of this Lease.

Regulations") having uniform applicability to all tenants of the Building

and enjoyment of the Building and the remainder of the Property; provided, that
the Rules and Regulations shall not materially interfere with the Tenant's use
and enjoyment of the Premises, in accordance with the provisions of this Lease,
for the purposes enumerated in the provisions of Section 3. The Tenant shall
adhere to the Rules and Regulations and shall cause its agents, employees,
invitees, visitors and guests to do so. A copy of the Rules and Regulations in

ground lease) take no action to interfere with the Tenant's rights hereunder,
except on the occurrence of an Event of Default.

     12.3. Anything contained in the provisions of this Section to the contrary
notwithstanding, any Mortgagee may at any time subordinate the lien of its

their respective dates of execution, delivery and/or recordation among the Land
Records of the said County, and thereafter such Mortgagee shall have the same
rights as to this Lease as it would have had, were this Lease executed and
delivered before the execution of such Mortgage.

written notice to Tenant. Landlord shall also have the option to recapture the
Premises upon thirty (30) days prior written notice to Tenant without

or all of the following actions:

            13.3.4. relet any or all of the Premises for the Tenant's account
for any or all of the remainder of the Term as hereinabove defined, or for a
period exceeding such remainder, in which event the Tenant shall pay to the
Landlord, at the times and in the manner specified by the provisions of Section
2, the Base Rent and any Additional Rent accruing during such remainder, less
any monies received by the Landlord, with respect to such remainder, from such
reletting, as well as the cost to the Landlord of any/25// attorneys' fees or of
any repairs or other action (including those taken in exercising the Landlord's
rights under any provision of this Lease) taken by the Landlord on account of
such Event of Default;     
    
            13.3.5. cure such Event of Default in any other manner (after giving
the Tenant written notice of the Landlord's intention to do so except as

suffered by the Landlord by reason of any Event of Default.

Tenant's exclusive remedy shall be an action for actual direct damages (Tenant
hereby waiving the benefit of any laws granting it a lien upon the property of
Landlord and/or upon rent due Landlord), but prior to any such action Tenant
will give Landlord written notice specifying such default with particularity,
and Landlord shall thereupon have thirty (30) days in which to cure any such
default. Unless and until Landlord fails to so cure any default after such
notice, Tenant shall not have any remedy or cause of

action by reason thereof. All obligations of Landlord hereunder will be
construed as covenants, not conditions, and all such obligations will be binding
upon Landlord only during the period of its possession of the Premises and not
thereafter. The term "Landlord" shall mean only the owner, for the time being of
the Premises, and in the event of the transfer by such owner of its interest in
the Premises, such owner shall thereupon be released and discharged from all
covenants and obligations of the Landlord thereafter accruing, but such
covenants and obligations shall be binding during the lease term upon each new
owner for the duration of such owner's ownership. Notwithstanding any other
provision hereof, Landlord shall not have any personal liability hereunder. In
the event of any breach or default by Landlord in any term or provision of this
Lease, Tenant agrees to look solely to the equity or interest then owned by
Landlord in the Property, however, in no event, shall any deficiency judgment or
any money judgment of any kind be sought or obtained against any Landlord.     

SECTION 14. ESTOPPEL CERTIFICATE.

     The Tenant shall from time to time, within five (5) days after being
requested to do so by the Landlord or any Mortgagee, execute, enseal,
acknowledge and deliver to the Landlord (or, at the Landlord's request, to any
existing or prospective purchaser, transferee, assignee or Mortgagee of any or
all of the Premises, the Property, any interest therein or any of the Landlord's
rights under this Lease) an instrument in recordable form,

     14.1. certifying (a) that this Lease is unmodified and in full force and
effect (or, if there has been any modification thereof, that it is in full force
and effect as so modified, stating therein the nature of such modification); (b)
as to the dates to which the Base Rent and any Additional Rent and other charges
arising hereunder have been paid; (c) as to the amount of any prepaid Rent or
any credit due to the Tenant hereunder; (d) that the Tenant has accepted
possession of the Premises, and the date on which the Term commenced; (e) as to
whether, to the best knowledge, information and belief of the signer of such
certificate, the Landlord or the Tenant is then in default in performing any of
its obligations hereunder (and, if so, specifying the nature of each such
default); and (f) as to any other fact or condition reasonably requested by the
Landlord or such other addressee; and

     14.2. acknowledging and agreeing that any statement contained in such
certificate may be relied upon by the Landlord and any such other addressee.

     14.3 In the event that Tenant fails to deliver in a timely manner the
estoppel certificate described in Section 14, Landlord may complete such a
certificate on behalf of Tenant, which certificate shall be binding against
Tenant as if Tenant itself signed such certificate. For such purpose, Tenant
hereby irrevocably constitutes and appoints Landlord as Tenant's attorney-in-
fact (which appointment shall be deemed coupled with an interest) for and in its
name to prepare and sign on Tenant's behalf such an estoppel certificate, Tenant
hereby ratifying and confirming all the said attorney shall lawfully do or
choose to do or be done by virture hereof, it being understood and agreed that
the aforesaid provisions impose no burden or obligation on the Landlord to do or
perform any act whatsoever. After said estoppel certificate has been prepared by
Landlord, Landlord shall provide Tenant a copy thereof. Unless Tenant modifies
such certificate as may be appropriate to make the certificate fully accurate,
and signs and returns to Landlord the certificate within three 

                                      -24-

(3) days after receipt from Landlord, Landlord shall be entitled and authorized
to sign such estoppel certificate and deliver to any Mortgagee or other person
such estoppel certificate in the name and on behalf of Tenant.

SECTION 15. QUIET ENJOYMENT.

     The Landlord hereby covenants that the Tenant, on paying the Rent and
performing the covenants set forth herein, shall peaceably and quietly hold and
enjoy, throughout the Term, (a) the Premises, and (b) such rights as the Tenant
may hold hereunder with respect to the remainder of the Property.

SECTION 16. NOTICES.

     Any notice, demand, consent, approval, request or other communication or
document to be provided hereunder to a party hereto shall be (a) given in

                         CURRENT RULES AND REGULATIONS


1.   The sidewalks, lobbies, passages, elevators and stairways shall not be
     obstructed by the Tenant and used by the Tenant for any purposes other than
     ingress and egress from and to the Tenant's offices. The Landlord shall in
     all cases retain the right to control or prevent access thereto by any
     person whose presence, in the Landlord's judgment, would be prejudicial to
     the safety, peace, character or reputation of the Building or of any tenant
     of the Property.

2.   The toilet rooms, water closets, sinks, faucets, plumbing and other service
     apparatus of any kind shall not be used by the Tenant for any purpose other
     than those for which they were installed, and no sweepings, rubbish, rags,
     ashes, chemicals or other refuse or injurious substances shall be placed
     therein or used in connection therewith by the Tenant, or left by the

     blind or curtain in the Premises, the Tenant shall not remove it without
     first obtaining the Landlord's written consent thereto.
    
4.   No sign, lettering, insignia, advertisement, notice or other thing shall be
     inscribed, painted, installed, erected or placed in any portion of the
     Premises which may be seen from outside the Building, or on any window,
     window space or other part of the exterior or interior of the Building,
     unless first approved in writing by the Landlord. Names on suite entrances
     shall be provided by and only by the Landlord and at the Tenant's expense,

     the other lettering in the Building, and first approved in writing by the
     Landlord. The Tenant shall/will not erect any stand, booth or showcase or
     other article or matter in or upon the Premises and/or the Building without
     first obtaining the Landlord's written consent thereto.

     door within the 

                                      -34-

     Premises or elsewhere upon the Property without Landlord's consent, and
     shall surrender all keys for all such locks at the end of the Term. The
     Landlord shall provide the Tenant with one set of keys to the Premises when
     the Tenant assumes possession thereof     

6.   The delivery of towels, ice, water, food, beverages, newspaper and other
     supplies, equipment and furniture will be permitted only under the
     Landlord's direction and control.

     interferes with the rights of any other tenant of the Property. The Tenant

     odor, or any kerosene, gasoline, benzine, camphene, fuel or other explosive
     or highly flammable material. No bird, fish or other animal shall be
     brought into or kept in or about the Premises.

8.   The Tenant shall keep the Premises in a good state of preservation and
     cleanliness while in possession of the Premises.

9.   If the Tenant desires to install signalling, telegraphic, telephonic,
     protective alarm or other wires, apparatus or devices within the Premises,
     the Landlord shall direct where and how they are to be installed and,
     except as so directed, no installation, boring or cutting shall be
     permitted. The Landlord shall have the right (a) to prevent or interrupt
     the transmission of excessive, dangerous or annoying current of electricity
     or otherwise into or through the Building or the Premises, (b) to require
     the changing of wiring connections or layout at the Tenant's expense, to
     the extent that the Landlord may deem necessary, (c) to require compliance
     with such reasonable rules as the Landlord may establish relating thereto,
     and (d) in the event of noncompliance with such requirements or rules,
     immediately to cut wiring or do whatever else it considers necessary to
     remove the danger, annoyance or electrical interference with apparatus in
     any part of the Building. Each wire installed by the Tenant must be
     clearly tagged at each distributing board and junction box and elsewhere
     where required by Landlord, with the number of the office to which such
     wire leads and the purpose for which it is used, together with the name of
     the tenant or other concern, if any, operating or using it.

10.  No furniture, package, equipment, supplies or merchandise may be received
     in the Building, or carried up or down in the elevators or stairways,
     except during such hours as are designated for such purpose by the
     Landlord, and only after Tenant gives notice thereof to the Landlord. The
     Landlord shall have the exclusive right to prescribe the method and manner
     in which any of the same is brought into or taken out of the Building, and
     the right to exclude from the Building any heavy furniture, safe or other
     article which may create a hazard and to require it to be located at a
     designated place in the Premises. The Tenant shall not place any weight
     anywhere beyond the safe carrying capacity of the Building. The cost of
     repairing any damage to the Building or any other part of the Property
     caused by taking any of the same in or out of the Premises, or any damage
     caused while it is in the Premises or the

     rest of the Building, shall be borne by the Tenant.

11.  Without the Landlord's prior written consent, (a) nothing shall be fastened
     to (and no hole shall be drilled, or nail or screw driven into) any wall or
     partition, (b) no wall, or partition shall be painted, papered or otherwise
     covered or moved in any way or marked or broken, (c) no connection shall be
     made to any electrical wire for running any fan, motor or other apparatus,
     device or equipment, (d) no machinery of any kind other than customary
     small business machinery shall be allowed in the Premises, (e) no
     switchboard or telephone wiring or equipment shall be placed anywhere other
     than where designated by the Landlord, and (f) no mechanic shall be allowed
     to work in or about the Building other than one employed by the Landlord,
     unless approved in writing by Landlord.

12.  The Tenant shall have access to the Premises at all reasonable times. The
     Landlord shall in no event be responsible for admitting or excluding any
     person from the Premises. In case of invasion, hostile attack,
     insurrection, mob violence, riot, public excitement or other commotion,
     explosion, fire or any casualty, the Landlord shall have the right to bar
     or limit access to the Building to protect the safety of occupants of the
     Property, or any property within the Property.

13.  The Landlord shall have the right to rescind, suspend or modify the Rules
     and Regulations and to promulgate such other Rules or Regulations as, in
     the Landlord's reasonable judgment, are from time to time needed for the
     safety, care, maintenance, operation and cleanliness of the Building, or
     for the preservation of good order therein. Upon the Tenant's having been
     given notice of the taking of any such action, the Rules and Regulations as
     so rescinded, suspended, modified or promulgated shall have the same force
     and effect as if in effect at the time at which the Tenant's lease was
     entered into (except that nothing in the Rules and Regulations shall be
     deemed in any way to alter or impair any provision of such lease).

14.  The use of any room within the Building as sleeping quarters is strictly
     prohibited at all times.

15.  The Tenant shall keep the windows and doors of the Premises (including
     those opening on corridors and all doors between rooms entitled to receive
     heating or air conditioning service and rooms not entitled to receive such
     service), closed while the heating or air conditioning system is operating,
     in order to minimize the energy used by, and to conserve the effectiveness
     of, such systems. The Tenant shall comply with all reasonable Rules and
     Regulations from time to time promulgated by the Landlord with respect to
     such systems or their use.

16.  Nothing in these Rules and Regulations shall give any Tenant any right or
     claim against the Landlord or any other person if the Landlord does not
     enforce any of them against any other 

                                      -36-

     tenant or person (whether or not the Landlord has the right to enforce them
     against such tenant or person), and no such nonenforcement with respect to
     any tenant shall constitute a waiver of the right to enforce them as to the
     Tenant or any other tenant or person.

                                by and between

                  MASSACHUSETTS MUTUAL LIFE INSURANCE COMPANY

                                      and

                           PULSAR DATA SYSTEMS, INC.

                                   EXHIBIT E

                                LEASE ADDENDUMS
    
1.   Option to Terminate: Provided Tenant is not then in default under the terms
of this Lease, Tenant shall have the one-time right to terminate this Lease as
of the end of the thirty-sixth (36th) month of the Lease Term. Tenant must
provide Landlord at least one hundred eighty (180) days prior written notice
(i.e. 180 days prior to the end of the 36th month of the Lease Term) of its
election to exercise this option to terminate. If Tenant fails to provide
Landlord with such written notice on or before such one hundred eighty (180) day
period, Tenant's option to terminate shall become null and void and Tenant shall
have no further option(s) to terminate. In connection with said termination and
as liquidated damages to compensate Landlord for the damage it will incur in
connection with an early termination, Tenant shall pay a fee to Landlord equal
to all unamortized tenant improvement costs and leasing commissions amortized
over sixty (60) months at a per annum rate of ten percent (10%) per annum plus
three (3) months Base Rent at the then current rates. The parties acknowledge
that it would be difficult to calculate Landlord's damages in the event of an
early termination and that the above sum is a reasonable estimate of such
damages. Tenant shall pay such sum at the time of its giving the foregoing
notice or such notice shall be null and void and Tenant's option to terminate
shall thereupon be null and void. In addition, the parties shall execute a
termination agreement in connection with such early termination.     

2.   Right of First Offer: As long as Tenant has not been in default during the
Term of the Lease and is not in default under the Lease at the time of its
exercise of this right, and so long as this right is exercised in connection
with an expansion of Tenant's Premises and for no other purpose, and subject to
the prior rights of any other tenant in the Building, Landlord hereby grants to
Tenant a one-time right of first offer on the terms and conditions contained in
this paragraph to lease the 6,717 square feet in Suite P when it becomes
available and is not subject to the rights of any other tenant (the "Offer
Space"). The rent for such Space shall be the same rate Tenant is then paying
for the Premises, as escalated. Such lease shall be coterminous with the lease
for the existing Premises and if such Term is then less than three (3) Lease
Years, the Term for the existing Premises and the Offer Space shall be extended
so that it will expire at least three (3) Lease Years from the commencement date
of Tenant's lease of the Offer Space. Landlord shall also provide Tenant with a
tenant improvement allowance in the amount equal to the proportionate amount
with respect to the Lease Term remaining for improvements to the Offer Space. In
the event the Offer Space becomes available for lease during the Term, Landlord
shall give notice thereof to Tenant which notice shall 

                                      -39-
<PAGE>
 
contain the foregoing terms to lease the Offer Space. Within five (5) business
days of such notice, time being of the essence, Tenant shall give Landlord
notice that it either does or does not wish to lease the Offer Space or if
Tenant fails to give Landlord notice of its desires respecting the Offer Space
within the foregoing required five (5) business day period, then Landlord shall
be entitled to proceed to market and/or lease the Offer Space to a third party
free and clear of Tenant's right to first offer and such right shall be deemed
terminated in all respects and Tenant shall have no further rights of first
offer.

In the event Tenant gives Landlord a notice as required in the preceding
paragraph that it wishes to lease the Offer Space, then Landlord and Tenant
shall have twenty (20) days from the date of the notice within which to amend
this Lease by adding the Offer Space on the terms and conditions contained in
Landlord's notice. In the event Landlord and Tenant fail to sign such amendment
to this Lease, using good faith efforts, within said twenty (20) day period,
time being of the essence, then Landlord shall be entitled to proceed to market
and/or lease the Offer Space to a third party free

to Audit:

(a)  Selection of Accountants:  If Tenant disputes the amount of an adjustment
or the proposed estimated increase or decrease in Taxes or Annual Operating
Costs, Tenant shall give Landlord written notice of such dispute within thirty
(30) days after Landlord advises Tenant of such adjustment or proposed increase
or decrease.  Tenant's failure to give such notice shall waive its right to
dispute the amounts so determined. Tenant shall also not be entitled to dispute
the foregoing amounts if Tenant is then in default hereunder. If Tenant is
entitled to and timely objects, Tenant shall have the right to engage its own
accountants ("Tenants Accountants") for the purposes of verifying the accuracy
of the statement in dispute, or the reasonableness of the adjustment or
estimated increase or decrease. If Tenant's Accountants determine that an error
has been made, Landlord and Tenant's Accountants shall endeavor to agree upon
the matter. If they cannot agree within twenty (20) days from the date Tenant's
Accountants commence reviewing Landlord's records, Landlord and Tenant's
Accountants shall jointly select an independent certified public accounting firm
(the "Independent Accountant") which firm shall conclusively determine whether
the adjustment or estimated increase or decreases is reasonable, and if not,
what amount is reasonable. Both parties shall be bound by such determination. If
Tenant's Accountants do not 

                                      -41-
<PAGE>
 
participate in choosing the Independent Accountant within 20 days from the date
Landlord and Tenant's Accountant's determine that they cannot agree as to
whether or not an error has been made, then Landlord's determination of the
adjustment or estimated increase or decrease shall be conclusively determined to
be reasonable and Tenant shall be bound hereby.

(b)  Payment of Costs:  All costs incurred by Tenant in obtaining Tenant's
Accountants and the cost of the Independent Accountant shall be paid by Tenant
unless Tenant's Accountants disclose an error, acknowledge by Landlord (or found
to have conclusively occurred by the Independent Accountant), of more than ten
percent (10%) in the computation of the total amount of Taxes or Annual
Operating Costs as set forth in the statement submitted by Landlord with respect
to the matter in dispute; in which event Landlord shall pay the reasonable costs
incurred by Tenant in obtaining such audits. No subtenant shall have the right
to conduct an audit and no assignee shall conduct an audit for any period during
which such assignee was not in possession of the Premises.

(c)   Continuation of Payments Pending Determination:  Tenant shall continue
to timely pay Landlord the amount of the prior year's adjustment and adjusted
Additional Rent determined to be incorrect as aforesaid until the parties have
concurred as to the appropriate adjustment or have deemed to be bound by the
determination of the Independent Accountant in accordance with the preceding
terms. Landlord's delay in submitting any statement contemplated herein for any
Lease Year shall not affect the provisions of this Paragraph, nor constitute a
waiver of Landlord's rights as set forth herein for said Lease Year or any
subsequent Lease Years during the Lease Term or any extensions thereof.

meets Landlord's reasonable criteria, which criteria are as follows:

a. The financial strength of the proposed assignee or subtenant, both in terms
of net worth and in terms of reasonably anticipated cash flow over the Lease
term, is not materially less than Tenant's financial strength at the time this
Lease was signed or at the time of such assignment or sublease, whichever is
greater.

b. The proposed assignee or subtenant will not burden the Premises and/or
Common Areas to an extent substantially disproportionate to typical tenants of
the Building, whether through disproportionate demand for landlord services or
utilities, disproportionate bearing weights on floor areas, disproportionate
parking requirements, deterioration of floors or other elements of the Building,
or otherwise.

c. The proposed assignee or subtenant does not intend to make substantial
alterations to the Premises which would, in Landlord's reasonable judgement,
result in a material net decrease in the value of the Premises as improved.

d. The proposed assignee's or subtenant's use of the Premises will, in
Landlord's sole judgment, be compatible with the uses of the other tenants in
the Building or will be appropriate for a Class A office building.

e. Any other basis on which Landlord can reasonably refuse to withhold its
consent to the proposed assignment or sublease, including any failure of the
proposed assignee or subtenant to meet any of the reasonable criteria of
Landlord that Tenant was required to meet prior to the execution of this Lease.

     release, or threatened release of any hazardous waste or substance by or
     on, under, about or from any of the properties. (b) Borrower has no
     knowledge of, or reason to believe that there has been (i) any use,
     generation, manufacture storage, treatment, disposal, release, or
     threatened release of any hazardous waste or substance on, under, about or

     the Agreement. Any inspections or tests made by Lender shall be at
     Borrower's expense and for Lender's purposes only and shall not be
     construed to create any responsibility or liability on the part of Lender
     to Borrower or to any other person. The representations and warranties
     contained herein are based on Borrower's due diligence in investigating the
     properties for hazardous waste and hazardous substances. Borrower hereby

     contribution in the event Borrower becomes liable for cleanup or other
     costs under any such laws, and (b) agrees to indemnify and hold harmless
     Lender against any and all claims, losses, liabilities, damages, penalties,
     and expenses which Lender may directly or indirectly sustain or suffer
     resulting from a breach of this section of the Agreement or as a
     consequence of any use, generation, manufacture, storage, disposal, release
     or threatened release of a hazardous waste or substance on the properties.
     The provisions of this section of the Agreement, including the obligation
     to indemnify, shall survive the payment of the indebtedness and the
     termination or expiration of this Agreement and shall not be affected by
     Lender's acquisition of any interest in any of the properties, whether by
     foreclosure or otherwise.     

     LITIGATION AND CLAIMS.  No litigation, claim, investigation, administrative
     proceeding or similar action (including those for unpaid taxes) against
     Borrower is pending or threatened, and no other event has occurred which
     may materially adversely affect Borrower's financial condition or
     properties, other than litigation, claims, or other events, if any, that
     have been disclosed to and acknowledged by Lender in writing.

     Borrower that are or were required to be filed, have been filed, and all
     taxes, assessments and other governmental charges have been paid in full,
     except those presently being or to be contested by Borrower in good faith

     been provided.

     SURVIVAL OF REPRESENTATIONS AND WARRANTIES.  Borrower understands and
     agrees that Lender, without independent investigation, is relying upon the
     above representations and warranties in extending Loan Advances to
     Borrower.  Borrower further agrees that the foregoing representations and
     warranties shall be continuing in nature and shall remain in full force and
     effect until such time as Borrower's Indebtedness shall be paid in full, or
     until this Agreement shall be terminated in the manner provided above,
     whichever is the last to occur.

AFFIRMATIVE COVENANTS.  Borrower covenants and agrees with Lender that, while
this Agreement is in effect, Borrower will:
    
     LITIGATION.  Promptly inform Lender in writing of (a) all material adverse
     changes in Borrower's financial condition, and (b) all existing and all
     threatened litigation, claims, investigations, administrative proceedings
     or similar actions affecting Borrower or any Guarantor which could
     materially affect the financial condition of Borrower or the financial
     condition of any Guarantor.     

     FINANCIAL RECORDS.  Maintain its books and records in accordance with
     generally accepted accounting principles, applied on a consistent basis,
     and permit Lender to examine and audit Borrower's books and records at all

     statements, lists of assets and liabilities, agings of receivables and
     payables, inventory schedules, budgets, forecasts, tax returns, and other

     operations as Lender may request from time to time.
    
     INSURANCE.  Maintain fire and other risk insurance, public liability
     insurance, and such other insurance as Lender may require with respect to
     Borrower's properties and operations, in form, amounts, coverages and with
     insurance companies reasonably acceptable to Lender. Borrower, upon request
     of Lender, will deliver to Lender from time to time the policies or
     certificates of insurance in form satisfactory to Lender, including
     stipulations that coverages will not be cancelled or diminished without at
     least ten (10) days' prior written notice to Lender.  Each insurance policy
     also shall include an endorsement providing that coverage in favor of
     Lender will not be impaired in any way by any act, omission or default of
     Borrower or any other person.  In connection with all policies covering
     assets in which Lender holds or is offered a security interest for the
     Loans, Borrower will provide lender with such loss payable or other
     endorsements as Lender may require.

     each existing insurance policy showing such information as Lender may

     (e) the then current property values on the basis of which insurance has
     been obtained, and the manner of determining those values; and (f) the
     expiration date of the policy. In addition, upon request of Lender (however
     not more often than annually), Borrower will have an independent appraiser

     replacement cost of any Collateral. The cost of such appraisal shall be
     paid by Borrower.

     OTHER AGREEMENTS.  Comply with all terms and conditions of all other
     agreements, whether now or hereafter existing, between Borrower and any
     other party and notify Lender immediately in writing of any default in

     imposed upon Borrower or its properties, income, or profits, prior to the
     date on which penalties would attach, and all lawful claims that, if
     unpaid, might become a lien or charge upon any of Borrower's properties,
     income, or profits. Provided however, Borrower will not be required to pay
     and discharge any such assessment, tax, charge, levy, lien or claim so long
     as (a) the legality of the same shall be contested in good faith by
     appropriate proceedings, and (b) Borrower shall have established on its
     books adequate reserves with respect to such contested assessment, tax,
     charge, levy, lien, or claim in accordance with generally accepted
     accounting practices.  Borrower, upon demand of Lender, will furnish to
     Lender evidence of payment of the assessments, taxes, charges, levies,
     liens and claims and will authorize the appropriate governmental official
     to deliver to Lender at any time a written statement of any assessments,
     taxes, charges, levies, liens and claims against Borrower's properties,
     income or profits.

     set forth in this Agreement and in the Related Documents in a timely
     manner, and promptly notify Lender if Borrower learns of the occurrence of

     records.  If Borrower now or at any time hereafter maintains any records
     (including without limitation computer generated records and computer
     software programs for the generation of such records) in the possession of
     a third party, Borrower, upon request of Lender, shall notify such party to
     permit Lender free access to such records at all reasonable times and to
     provide Lender with copies of any records it may request, all at Borrower's
     expense.

     at least annually and at the time of each disbursement of Loan proceeds
     with a certificate executed by Borrower's chief financial officer, or other
     officer or person acceptable to Lender, certifying that the representations
     and warranties set forth in this Agreement are true and correct as of the
     date of the certificate and further certifying that, as of the date of the
     certificate, no Event of Default exists under this Agreement.

     result of an intentional or unintentional action or omission on its part or
     on the part of any third party, on property owned and/or occupied by
     Borrower, any environmental activity where damage may result to the
     environment, unless such environmental activity is pursuant to and in
     compliance with the conditions of a permit issued by the appropriate
     federal, state or local governmental authorities; shall furnish to Lender
     promptly and in any event within thirty (30) days after receipt thereof a

     connection with any environmental activity whether or not there is damage
     to the environment and/or other natural resources.     

     ADDITIONAL ASSURANCES.  Make, execute and deliver to Lender such promissory
     notes, mortgages, deeds of trust, security agreements, financing
     statements, instruments, documents and other agreements as Lender or its
     attorneys may reasonably request to evidence and secure the Loans and to
     perfect all Security Interests.

NEGATIVE COVENANTS.  Borrower covenants and agrees with Lender that while this
Agreement is in effect, Borrower shall not, without the prior written consent of
Lender:

     (as defined in the Internal Revenue Code of 1966, as amended), Borrower may
     pay cash dividends on its stock to its shareholders from time to time in
     amounts necessary to enable the shareholders to pay income taxes and make
     estimated income tax payments to satisfy their liabilities under federal
     and state law which arise solely from their status as Shareholders of a
     Subchapter S Corporation because of their ownership of shares of stock of
     Borrower, or (d) purchase or retire any of Borrower's outstanding shares or

CESSATION OF ADVANCES.  If Lender has made any commitment to make any Loan to
Borrower, whether under this Agreement or under any other agreement, Lender
shall have no obligation to make Loan Advances or to disburse Loan proceeds if:
(a) Borrower or any Guarantor is in default under the terms of this Agreement or
any of the Related Documents or any other agreement that Borrower or any
Guarantor has with Lender; (b) Borrower or any Guarantor becomes insolvent,
files a petition in bankruptcy or similar proceedings, or is adjudged a
bankrupt; (c) there occurs a material adverse change in Borrower's financial
condition, in the financial condition of any Guarantor, or in the value of any

attempts to limit, modify or revoke such Guarantor's guaranty of the Loan or any
other loan with Lender; or (e) Lender in good faith deems itself insecure, even
though no Event of Default shall have occurred.     

RIGHT OF SETOFF.  Borrower grants to Lender a contractual security interest in,
and hereby assigns, conveys, delivers, pledges, and transfers to Lender all
Borrower's right, title and interest in and to, Borrower's accounts with Lender
(whether checking, savings, or some other account), including without limitation
all accounts held jointly with someone else and all accounts Borrower

================================================================================

may open in the future, excluding however all IRA and Keogh accounts, and all
trust accounts, and all trust accounts for which the grant of a security
interest would be prohibited by law. Borrower authorizes Lender, to the extent
permitted by applicable law, to charge or setoff all sums owing on the
Indebtedness against any and all such accounts.

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

     DEFAULT ON INDEBTEDNESS.  Failure of Borrower to make any payment when due
     on the Loans.

     OTHER DEFAULTS.  Failure of Borrower or any Grantor to comply with or to
     perform when due any other term, obligation, covenant or condition
     contained in this Agreement or in any of the Related Documents, or failure
     of Borrower to comply with or to perform any other term, obligation,
     covenant or condition contained in any other agreement between Lender and
     Borrower.
    
     DEFAULT IN FAVOR OF THIRD PARTIES.  Should Borrower or any Grantor default
     under any loan, extension of credit, security agreement, purchase or sales
     agreement, or any other agreement, in favor of any other creditor or person
     that may materially affect any of Borrower's property or Borrower's or any
     Grantor's ability to repay the Loans or perform their respective
     obligations under this Agreement or any of the Related Documents.     

     FALSE STATEMENTS.  Any warranty, representation or statement made or
     furnished to Lender by or on behalf of Borrower or any Grantor under this
     Agreement or the Related Documents is false or misleading in any material
     respect at the time made or furnished, or becomes false or misleading at
     any time thereafter.
    
     DEFECTIVE COLLATERALIZATION.  This Agreement or any of the Related
     Documents ceases to be in full force and effect (including failure of any
     Security Agreement to create a valid and perfected Security Interest) at
     any time and for any reason.     
    
     INSOLVENCY.  The dissolution or termination of Borrower's existence as a
     going business, the insolvency of Borrower, the appointment of a receiver
     for any part of Borrower's property, any assignment for the benefit of
     creditors, any type of creditor workout, or the commencement of any
     proceeding under any bankruptcy or insolvency laws by or against 
     Borrower.     

     CREDITOR OR FORFEITURE PROCEEDINGS.  Commencement of foreclosure or
     forfeiture proceedings, whether by judicial proceeding, self-help,
     repossession or any other method, by any creditor of Borrower, any creditor
     of any Grantor against any collateral securing the indebtedness, or by any
     governmental agency.  This includes a garnishment, attachment, or 
<PAGE>
 
                            BUSINESS LOAN AGREEMENT                      Page 13

================================================================================

     levy on or of any of Borrower's deposit accounts with Lender. However, this
     Event of Default shall not apply if there is a good faith dispute by
     Borrower or Grantor, as the case may be, as to the validity or
     reasonableness of the claim which is the basis of the creditor or
     forfeiture proceeding, and if Borrower or Grantor gives Lender written
     notice of the creditor or forfeiture proceeding and furnishes reserves or a
     surety bond for the creditor or forfeiture proceeding satisfactory to
     Lender.
    
     EVENTS AFFECTING GUARANTOR.  Any of the preceding events occurs with
     respect to any Guarantor of any of the indebtedness or any Guarantor dies
     or becomes incompetent, or revokes or disputes the validity of, or
     liability under, any Guaranty of the indebtedness. Lender, at its option,
     may, but shall not be required to, permit the Guarantor's estate to assume
     unconditionally the obligations arising under the guaranty in a manner
     satisfactory to Lender, and, in so doing, cure the Event of Default.     

     CHANGE IN OWNERSHIP.  Any change in ownership of twenty-five percent (25%)
     or more of the common stock of Borrower.

     ADVERSE CHANGE.  A material adverse change occurs in Borrower's financial
     condition, or Lender believes the prospect of payment or performance of the
     indebtedness is impaired.

          EVENTS AFFECTING GUARANTOR.  Any of the proceeding events occurs with
          respect to any Guarantor of any of the indebtedness or any Guarantor
          dies or becomes incompetent, or revokes or disputes the validity of,
          or liability under, any Guaranty of the indebtedness.

    
     

    
     

     INSECURITY.  Lender, in good faith, deems itself insecure.

     RIGHT TO CURE.  If any default, other than a Default on Indebtedness, is
     curable and if Borrower or Grantor, as the case may be, has not been given
     a notice of a similar default within the preceding twelve (12) months, it
     may be cured (and no Event of Default will have occurred) if Borrower or
     Grantor, as the case may be, after receiving written notice from Lender
     demanding cure of such default: (a) cures the default within fifteen (15)
     days; or (b) if the cure requires more than fifteen (15) days, immediately
     initiates steps which Lender deems in Lender's sole discretion to be
     sufficient to cure the default and thereafter continues and completes all
     reasonable and necessary steps sufficient to produce compliance as soon as
     reasonably practical.

================================================================================

    
EFFECT OF AN EVENT OF DEFAULT.  If any Event of Default shall occur, except
where otherwise provided in this Agreement or the Related Documents, all
commitments and obligations of Lender under this Agreement or the Related
Documents or any other agreement immediately will terminate, and, at Lender's
option, all indebtedness immediately will become due and payable, all without
notice of any kind to Borrower, except that in the case of an Event of Default
of the type described in the "Insolvency" subsection above, such acceleration
shall be automatic and not optional.  In addition, Lender shall have all the
rights and remedies provided in the Related Documents or available at law, in
equity, or otherwise.  Except as may be prohibited by applicable law, all of
Lender's rights and remedies shall be cumulative and may be exercised singularly
or concurrently.  Election by Lender to pursue any remedy shall not exclude
pursuit of any other remedy, and an election to make expenditures or to take
action to perform an obligation of Borrower or of any Grantor shall not affect
Lender's right to declare a default and to exercise its rights and 
remedies.     

MISCELLANEOUS PROVISIONS.  The following miscellaneous provisions are a part of
this Agreement.

     AMENDMENTS.  This Agreement, together with any Related Documents,
     constitutes the entire understanding and agreement of the parties as to the
     matters set forth in this Agreement.  No alteration of or amendment to this
     Agreement shall be effective unless given in writing and signed by the
     party or parties sought to be charged or bound by the alteration or
     amendment.

     APPLICABLE LAW.  This Agreement has been delivered to Lender and accepted
     by Lender in the State of California.  If there is a lawsuit, Borrower
     agrees upon Lender's request to submit to the jurisdiction of the courts of
     Orange County, the State of California.  This Agreement shall be governed
     by and construed in accordance with the laws of the State of California.

     CAPTION HEADINGS.  Caption headings in this Agreement are for convenience
     purposes only and are not to be used to interpret or define the provisions
     of this Agreement.

     MULTIPLE PARTIES; CORPORATE AUTHORITY.  All obligations of Borrower under
     this Agreement shall be joint and several, and all references to Borrower
     shall mean each and every Borrower.  This means that each of the Borrowers
     signing below is responsible for all obligations of this Agreement.

     CONSENT TO LOAN PARTICIPATION.  Borrower agrees and consents to Lender's
     sale or transfer, whether now or later, of one or more participation
     interests in the Loans to one or more purchasers, whether related or
     unrelated to Lender.  Lender may provide, without any limitation
     whatsoever, to any one or more purchasers, or potential purchasers, any
     information or knowledge Lender may have about Borrower or about any other
     matter relating to the Loan, and Borrower hereby waives any rights to
     privacy it may have with 
<PAGE>
 
                            BUSINESS LOAN AGREEMENT                      Page 15
                                  (Continued)
================================================================================

     respect to such matters. Borrower additionally waives any and all notices
     of sale of participation interests, as well as all notices of any
     repurchase of such participation interests. Borrower also agrees that the
     purchasers of any such participation interests will be considered as the
     absolute owners of such interests in the Loans and will have all the rights
     granted under the participation agreement or agreements governing the sale
     of such participation interests. Borrower further waives all rights of
     offset or counterclaim that it may have now or later against Lender or
     against any purchaser of such participation interest and unconditionally
     agrees that either Lender or such purchaser may enforce Borrower's
     obligation under the Loans irrespective of the failure or insolvency of any
     holder of any interest in the Loans. Borrower further agrees that the
     purchaser of any such participation interests may enforce its interests
     irrespective of any personal claims or defenses that Borrower may have
     against Lender.

     COSTS AND EXPENSES.  Borrower agrees to pay upon demand all of Lender's
     expenses, including without limitation reasonable attorneys' fees, incurred
     in connection with the preparation, execution, enforcement, modification
     and collection of this Agreement or in connection with the Loans made
     pursuant to this Agreement.  Lender may pay someone else to help collect
     the Loans and to enforce this Agreement, and Borrower will pay that amount.
     This includes, subject to any limits under applicable law, Lender's
     reasonable attorneys' fees and Lender's legal expenses, whether or not
     there is a lawsuit, including reasonable attorneys' fees for bankruptcy
     proceedings (including efforts to modify or vacate any automatic stay or
     injunction), appeals, and any anticipated post-judgment collection
     services.  Borrower also will pay any court costs, in addition to all other
     sums provided by law.

     NOTICES.  All notices required to be given under this Agreement shall be
     given in writing, may be sent by telefacsimille (unless otherwise required
     by law), and shall be effective when actually delivered or when deposited
     with a nationally recognized overnight courier or deposited in the United
     States mail, first class, postage prepaid, addressed to the party to whom
     the notice is to be given at the address shown above.  Any party may change
     its address for notices under this Agreement by giving formal written
     notice to the other parties, specifying that the purpose of the notice is
     to change the party's address.  To the extent permitted by applicable law,
     if there is more than one Borrower, notice to any Borrower will constitute
     notice to all Borrowers.  For notice purposes, Borrower agrees to keep
     Lender informed at all times of Borrower's current address(es).

     SEVERABILITY.  If a court of competent jurisdiction finds any provision of
     this Agreement to be invalid or unenforceable as to any person or
     circumstance, such finding shall not render that provision invalid or
     unenforceable as to any other persons or circumstances.  If feasible, any
     such offending provision shall be deemed to be modified to be within the
     limits of enforceability or validity; however, if the offending provision
     cannot be so modified, it shall be stricken and all other provisions of
     this Agreement in all other respects shall remain valid and enforceable.

     SUBSIDIARIES AND AFFILIATES OF BORROWER.  To the extent the context of any
     provisions of this Agreement makes it appropriate, including without
     limitation any representation, warranty or covenant, the word "Borrower" as
     used herein shall include all subsidiaries and affiliates of Borrower.
     Notwithstanding the foregoing however, under no circumstances shall this
     Agreement be construed to require Lender to make any Loan or other
     financial accommodation to any subsidiary or affiliate of Borrower.     

     SUCCESSORS AND ASSIGNS.  All covenants and agreements contained by or on
     behalf of Borrower shall bind its successors and assigns and shall inure to
     the benefit of Lender, its successors and assigns.  Borrower shall not,
     however, have the right to assign its rights under this Agreement or any
     interest therein, without the prior written consent of Lender.

     SURVIVAL.  All warranties, representations, and covenants made by Borrower
     in this Agreement or in any certificate or other instrument delivered by
     Borrower to Lender under this Agreement shall be considered to have been
     relied upon by Lender and will survive the making of the Loan and delivery
     to Lender of the Related Documents, regardless of any investigation made by
     Lender or on Lender's behalf.

     TIME IS OF THE ESSENCE.  Time is of the essence in the performance of this
     Agreement.

     WAIVER.  Lender shall not be deemed to have waived any rights under this
     Agreement unless such waiver is given in writing and signed by Lender.  No
     delay or omission on the part of Lender in exercising any right shall
     operate as a waiver of such right or any other right.  A waiver by Lender
     of a provision of this Agreement shall not prejudice or constitute a waiver
     of Lender's right otherwise to demand strict compliance with that provision
     or any other provisions of this Agreement.  No prior waiver by Lender, nor
     any course of dealing between Lender and Borrower, or between Lender and
     any Grantor, shall constitute a waiver of any of Lender's rights or of any
     obligations of Borrower or of any Grantor as to any future transactions.
     Whenever the consent of Lender is required under this Agreement, the
     granting of such consent by Lender in any instance shall not constitute
     continuing consent in subsequent instances where such consent is required,
     and in all cases such consent may be granted or withheld in the sole
     discretion of Lender.

                THIRD AMENDMENT TO LOAN AND SECURITY AGREEMENT
                ----------------------------------------------

     This Third Amendment to Loan and Security Agreement (this "Amendment") is 
made and entered into effective as of March 31, 1999, by and among Litronic

modified, the "Original Agreement"), dated as of June 27, 1996, and FFOC has 
assigned all of its right, title and interest in, to and under the Agreement to 
Fidelity. The Original Agreement as amended by this Amendment is referred to 
herein as the "Agreement." Capitalized terms used but not defined in this 
Amendment shall have the meanings given to them in the Original Agreement. The 
Company and Fidelity desire to amend the Original Agreement and, in connection 
therewith, hereby agree as follows:

     1.   The definition of "TANGIBLE NET WORTH REQUIREMENT" in Section 8.8 of 
the Original Agreement hereby is amended to read in its entirety as follows:

          "TANGIBLE NET WORTH REQUIREMENT" means negative $6,200,000 plus the 
net proceeds received by the Company from any such sale of its equity securities
after the date hereof.

     2.   The definition of "WORKING CAPITAL REQUIREMENT" in Section 8.10 of the
Original agreement hereby is amended to read in its entirety as follows:

          "WORKING CAPITAL REQUIREMENT" means negative $1,000,000 plus the net 
proceeds received by the Company from any sale of its equity securities after 
the date hereof.

     3.   Section 8.9 of the Original Agreement hereby is deleted in its 
entirety and shall be of no further force or effect:

     4.   A new clause (o) reading in its entirety as follows hereby is added to
Section 12 of the Original Agreement.

          (o)  The Company shall fail to consummate and complete the offering 
and sale of its equity securities on or prior to May 31, 1999 resulting in net 
proceeds to the Company of at least $20,000,000.

     5.   In order to induce Fidelity to enter into this Amendment, the Company 
represents and warrants to Fidelity that:

          (a)  The representations and warranties contained in Section 7 of the 
Original Agreement are true and correct at and as of the time of the
effectiveness hereof.
<PAGE>
 
          (b)  The Company is duly authorized to execute, deliver and perform 
its obligations under this Amendment and is and will continue to be duly 
authorized to perform its obligations under the Original Agreement as amended 
hereby. The Company has duly taken all corporate action necessary to authorize 
the execution and delivery of this Amemdment and to authorize the performance of
the obligations of the Company hereunder.

          (c)  The execution and delivery by the Company of this Amemdment, the 
performance by the Company of its obligations hereunder and the consummation of 
the transactions contemplated hereby do not and will not conflict with any 
provision of law, statute, rule or regulation or of the articles of
incorporation and bylaws of the Company, or of any material agreement, judgment,
license, order or permit applicable to or binding upon the Company, or result in
the creation of any lien, charge or encumbrance upon any assets or properties of
the Company. Except for those which have been duly obtained, no consent,
approval, authorization or order of any court or governmental authority or third
party is required in connection with the execution and delivery by the Company
of this Amendment or to consummate the transactions contemplated hereby.

          (d)  The Agreement (including this Amendment) has been duly executed 
and delivered by the Company and is a legal and binding instrument and agreement
of the Company, enforceable against the Company in accordance with its terms, 
except as limited by bankruptcy, insolvency and similar laws and by general 
principles of equity.

          (e)  No Event of Default or any event that, with the giving of notice,
the passage of time or both, would constitute an Event of Default has occurred 
or is continuing.

     6.   (a)  The Agreement is hereby ratified and confirmed in all respects. 
The execution, delivery and effectiveness of this Amendment shall not, except as
expressly provided herein, operate as a waiver of any right, power or remedy of 
Fidelity under the Agreement nor constitute a waiver of any provision thereof.

          (b)  All representations, warranties, covenants and agreements of the 
Company herein shall survive the execution and delivery of this Amendment and 
the performance hereof and shall further survive until the Agreement is 
terminated.

          (c)  This Amendment may be separately executed in counterparts and by 
the different parties hereto in separate counterparts, each of which when so 
executed shall be deemed to constitute one and same Amendment.

          (d)  The Company shall pay to Fidelity a documentation fee of $1,000 
in connection with the execution and delivery thereof.

Fidelity finally approves a line of credit for the Prospects on substantially 
the same terms and conditions outlined in the Letter and the Prospects do not

thereof, the Company shall pay to Fidelity a fee of $100,000 on such 60/th/ 
day. The Company may not terminate this Agreement prior to such 60/th/ day 
without paying such fee unless this Agreement is terminated in connection with 
the closing with Fidelity of the line of credit outlined in the Letter.

     IN WITNESS WHEREOF, the Company and Fidelity have executed this Amendment 
as of the date first written above.

We consent to the use of our report February 26, 1999, related to the

The Board of Directors
Pulsar Data Systems, Inc.

Our report dated March 31, 1999, contains an explanatory paragraph that states 
that the Company has suffered losses from operations and has a net working 
capital deficit, which raise substantial doubt about its ability to continue as 
a going concern.  The financial statements do not include any adjustments that 
might result from the outcome of that uncertainty.

We consent to the use of our report included herein and to the reference to our 
firm under the headings "Selected Financial Data Pulsar" and "Experts" in the
prospectus.

To The Board of Directors
Pulsar Data Systems, Inc.
Lanham, Maryland

The audits referred to in our report dated April 27, 1998, which contains an 
explanatory paragraph that states that the Company incurred a loss, has a net
capital deficiency and was in violation of certain debt convenants, among
other factors, raise substantial doubt about the Company's ability to continue
as a going concern.

Our audits were made for the purpose of forming an opinion on the basic 
financial statements taken as a whole.  The supplemental Schedule II, Valuation 
and Qualifying Accounts and Reserves is presented for purposes of complying with
the Securities and Exchange Commission's rules and is not a part of the basic 
financial statements.  This schedule has been subjected to the auditing 
procedures applied in our audits of the basic financial statements and, in our 
opinion, is fairly stated in all material respects in relation to the basic 
financial statements taken as a whole.

We consent to the use of our reports included herein and to the reference to our
firm under the heading "Experts" in the prospectus.
