                               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, the stockholders of Litronic Industries,
Inc. will exchange all of their outstanding common stock 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" or "our"
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 business
   
   Litronic provides professional Internet data security services and develops
and markets software and microprocessor-based products needed to secure
electronic commerce business transactions 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.
Our Internet security products can be used with world-wide-web browsers,
including Netscape Communicator and Microsoft Internet Explorer, to facilitate
secure electronic commerce transactions and other data communications, such as
secure e-mail.     
       
          
Strategic relationships     
   
   We have 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 Corp.

    semi-conductor industries; and

significantly increase our revenue. Litronic incurred net losses of $1.4
million for the year ended December 31, 1998 and $973,000 for the three months
ended March 31, 1999. Pulsar incurred net losses of $8.1 million for the year
ended December 31, 1998 and $1.8 million for the three months ended March 31,
1999. Our pro forma combined statements of operations reflect net losses of
$11.4 million for the year ended December 31, 1998 and $3.1 million for the
three months ended March 31, 1999.     
       
Our inability to integrate, or implement our plans for, the operations of
Pulsar may adversely affect our business.
   
   Our failure to successfully integrate, or implement our plans for, the
operations of Pulsar would significantly diminish the value of the Pulsar
acquisition and adversely affect our future operations. Moreover, 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 and
    coordinate our marketing and sales efforts;     
     
  . roll out our 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.     
      
   We may not be able to successfully implement any of these plans.     
 
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 $33.4 million, or 56%, of our pro forma combined, as adjusted,
assets as of March 31, 1999, consisted of intangible assets, including
goodwill, arising from the acquisition of Pulsar. This amount, the components
of which will be amortized over 10 to 15 years, constitutes a non-cash, non-tax
deductible expense in each amortization period 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.
This means that if we default on our secured debt obligations our indebtedness
could become immediately due and payable     
 
                                       9
<PAGE>
 
   
and 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 had to negotiate with our lenders for waivers or forbearance agreements
for these violations.     
 
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 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.
 
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. 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. 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. For the three months ended March 31, 1999, Litronic
derived 71% of its revenue from three customers and Pulsar derived 18% of its
revenue from one customer.     
 
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 and 86% of our pro forma
combined revenue for the three months ended March 31, 1999. Our sales to these
agencies are subject to risks, including:     
       
  . early termination of our contracts;
     
  . disallowance of costs upon audit; and     
          
  . the necessity to participate in competitive bidding and proposal
    processes, which is costly, time consuming and may result in unprofitable
    contracts.     
 
   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 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;     
     
  . the Internet infrastructure and communications services to support
    electronic commerce may not be able to continue to support the demands
    placed on it by continued growth; and     
          
  . 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.     
         
       
       
If PKI technology is compromised, our business would be adversely affected.
   
   Many of our products are based on PKI technology. 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. The occurrence of any of the following could result in a decline in
demand for our data security products:     
          
  . any significant advance in techniques for attacking PKI systems,
    including the development of an easy factoring method or faster, more
    powerful computers;     
          
  . publicity of the successful decoding of cryptographic messages or the
    misappropriation of private keys; and     
     
  .  government regulation limiting the use, scope or strength of PKI.     
 
If we do not respond to rapid technological changes, our products and service
offerings could become obsolete.
   
   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.
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 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 the 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 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     
 
                                       11
<PAGE>
 
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.
 
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 us. We have not
entered into employment agreements with any employees other than Messrs. Shah
and Davis. Even with these agreements, there is a risk that these individuals
will not continue to serve for any particular period of time. While we have
obtained 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 service our software and
hardware systems, customers and potential customers or 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 and the costs of hiring and
retaining these individuals are high. Even if we are able to hire these
individuals, we may be unable to retain them. Furthermore, there is increasing
pressure to provide technical employees with stock options and other equity
interests, 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
product defects or 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 us, 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
products or solutions, could adversely affect our business reputation.     
 
                                       12
<PAGE>
 
   
   Furthermore, 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; and     
 
  . 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.     
       
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. 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 or services. We cannot
predict the extent to which we might be liable for these costs, but it is
conceivable in general that year 2000 errors could result in substantial
judgments against us or other providers of information technology. 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.
       
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.
   
   Our business, financial condition and operating results could be adversely
affected if we are unable to protect our intellectual property rights.
Notwithstanding the precautions we take, third     
 
                                       13
<PAGE>
 
   
parties may copy or 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 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.     
 
We may face claims of infringement of proprietary rights.
   
   There is a risk that our products infringe the proprietary rights of third
parties. In addition, whether or not our products infringe on proprietary
rights of third parties, infringement or invalidity claims may be asserted or
prosecuted against us and we could incur significant expense in defending them.
If any claims or actions are asserted against us, we may be required to modify
our products or seek licenses for these intellectual property rights. We may
not be able to modify our products or obtain licenses on commercially
reasonable terms, in a timely manner or at all. Our failure to do so could
adversely affect our business.     
       
       
Our efforts to expand international operations are subject to a number of
risks.
   
   We are currently seeking to increase our international sales. Our inability
to maintain or to obtain federal or foreign regulatory approvals relating to
the import or export of our products on a timely basis could adversely affect
our ability to expand our international business. Additionally, our
international operations could be subject to a number of risks, any of which
could adversely affect our future international sales, including:     
       
  . 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 a third-party supplier,
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 our 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 62.0% of our outstanding common stock. These
stockholders, if acting together, would have the ability to elect our directors
    
                                       14
<PAGE>
 
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 $15.3 million, or 48.4% of the net proceeds of this
offering to reduce outstanding indebtedness, including approximately $9.0
million of indebtedness assumed in connection with the acquisition of Pulsar,
and $1.1 million, or 3.5%, of the net proceeds to fund settlements with several
of Pulsar's trade vendors. Consequently, these funds will not be available to
fund future growth. The $15.3 million of indebtedness being repaid 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 which, if resolved against Pulsar, could
materially and adversely affect our business and financial condition. These
lawsuits claim: (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. See
"Business--Legal Proceedings."     
       
       
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 or prevent an acquisition not approved
by our board of directors, or that may adversely affect the price of our common
stock. See "Description of Securities."

<PAGE>
 
       
       
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 equity 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.     
 
                           FORWARD-LOOKING STATEMENTS
   
   You should not rely on forward-looking statements in this prospectus. This
prospectus contains forward-looking statements that involve risks and
uncertainties. These statements relate to our future plans, objectives,
expectations and intentions and may be identified by the use of words such as
expects, anticipates, intends, and plans and other similar expressions. Our
actual results will differ from those discussed in these statements and you may
consider these differences important to your investment decision. Factors that
could contribute to these differences include those discussed in the "Risk
Factors" section and elsewhere in this prospectus. This prospectus also
contains forward-looking statements attributed to third parties relating to
their estimates regarding market growth. You should not place undue reliance on
the forward-looking statements in this prospectus, which speak only as of the
date the statement is made.

                                USE OF PROCEEDS
   
   The net proceeds we will receive from the sale of common stock in this
offering are estimated to be approximately $31.6 million or $36.7 million if
the representatives' over-allotment option is exercised in full. These amounts
assume we receive an initial public offering price of $10.00 per share, which
is the midpoint of the currently anticipated range of the initial public
offering price, and include deductions for 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 July 31, 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.     
     
  . $3.6 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, and is secured by property pledged by a
    family member of Mr. Davis.     
     
  . $3.3 million to repay in full six promissory notes payable to various
    vendors, which bear interest at annual rates ranging from 10% to 18% and
    are due in May and June 1999.     
     
  . $1.4 million to IBM Global Finance Corporation 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 secured by
    substantially all of the assets of Pulsar as well as by assets pledged by
    Mr. Davis and Ms. Davis. This $1.4 million payment will eliminate the
    pledge of assets by Mr. Davis and Ms. Davis.     
     
  . $650,000 to pay IBM Global under its forbearance agreement with Pulsar
    which becomes payable upon closing of this offering. The obligations
    under the forbearance agreement are guaranteed by Mr. Davis and Ms. Davis
    and secured by assets pledged by Mr. Davis.

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.
       
Vendor settlements     
   
   We expect to use the proceeds allocated to vendor settlements to pay amounts
owed under litigation settlements with various Pulsar trade vendors, as well as
anticipated amounts to pay as-yet-unsettled claims filed against Pulsar by
other trade vendors.     
 
Working capital and general corporate purposes
   
   If our cash from operations proves to be insufficient to fund our
outstanding trade payables, including up to approximately $3.1 million of
accounts payable more than 90 days overdue, we may use a portion of the
proceeds to fund these obligations. In addition, 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
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 $5.1
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, certificates of
deposit or other 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 substantially all of our personal and real property as
collateral.     
 
                                       18

   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 and an
anticipated increase in rent expense for our California operations of $400,000
per year following our anticipated relocation of our California headquarters.
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 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. 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.
    
                                    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 March 31, 1999, the net tangible book value (deficit) of Litronic was
$(5.2 million), or $(1.34) 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 3,700,000 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 March 31, 1999 would have been $14.7
million or $1.51 per share. This represents an immediate increase in net
tangible book value of $2.85 per share to existing stockholders and an
immediate dilution of $8.49 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 March 31, 1999,
and giving retroactive effect to the Pulsar acquisition, the differences
between the number of shares of common stock purchased from us, the total
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
 
  . assumed an average price per share of $10.00 for new investors and for
    the fair value of the common stock issued in connection with the Pulsar
    acquisition.

   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 $42.6 million, based on an assumed offering price
of $10.00 per share, for 4,255,000 shares of common stock, representing
approximately 56.0% of the total consideration for 41.3% 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
     
  . 370,000 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.

                      SELECTED FINANCIAL DATA--PULSAR     
                  
               (dollars in thousands, except per share data)     
   
   The following table presents selected financial data as of and for each of
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
financial data as of and for the year ended December 31, 1998 is derived from
the financial statements of Pulsar which have been audited by KPMG LLP,
independent certified public accountants. The financial statements of Pulsar as
of December 31, 1997 and 1998, and for each of the years in the three-year
period ended December 31, 1998, and the related reports are included elsewhere
in this prospectus.     
   
   The selected data presented below for the three month periods ended March
31, 1998 and 1999, and as of March 31, 1999, are derived from the unaudited
condensed financial statements of Pulsar included elsewhere in this prospectus.
    
   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
of debt covenants and net capital deficiency raise substantial doubt about the
entity's ability to continue as a going concern. The financial statements and
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 and the three months ended March 31, 1999 give
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 March 31, 1999 gives effect to the acquisition and this
offering as if these transactions had occurred as of March 31, 1999. 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 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
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.
   
   Before 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 $15.0 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.     
 
   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.
          
Results of operations--comparison of the three months ended March 31, 1998 and
1999     
   
 Litronic     
   
   Total revenue. Total revenue decreased 15% from $1.7 million during the
three months ended March 31, 1998 to $1.4 million during the three months ended
March 31, 1999. The decrease was primarily attributable to decreased sales of
the ARGUS 300 products to the U.S. Army Corps of Engineers and readers to
Lockheed Martin Corporation under the Defense Messaging System contract.     
   
   During the three months ended March 31, 1998, Litronic derived 36%, 35% and
16% of its revenue from sales to Lockheed Martin Corporation, U.S. Army Corps
of Engineers and the National Security Agency. During the three months ended
March 31, 1999, Litronic derived 39%, 27%, and     
 
                                       30
<PAGE>
 
   
5% 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 51% and 32%
of Litronic's sales during the three months ended March 31, 1998 and 1999.     
   
   Product revenue. Product revenue decreased 35% from $1.4 million in the
three months ended March 31, 1998 to $885,000 in the three months ended March
31, 1999. This decrease 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 Corps of Engineers Financial Management Services, or CEFMS,
contract and reduced sales of reader/writers to Lockheed Martin Corporation
under the Defense Messaging System contract. We expect that sales of our ARGUS
300 products 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.     
   
   License and service revenue. License and service revenue increased from
$309,000 during the three months ended March 31, 1998 to $525,000 during the
three months ended March 31, 1999. This change is primarily due to $369,000 of
revenue related to the Forte project offset by a decrease of $246,000 in
revenue from the National Security Agency Defense Messaging System support
services.     
   
   Total gross margin. Total gross margin increased as a percentage of revenue
from 49% during the three months ended March 31, 1998 to 54% during the three
months ended March 31, 1999. The increase was due primarily to a change in
revenue mix comprised of decreased sales of the ARGUS 300 products to the U.S.
Army Corps of Engineers and increased higher margin license and service
revenue.     
   
   Product gross margin. Product gross margins decreased as a percentage of net
product revenue from 51% during the three months ended March 31, 1998 to 43%
during the three months ended March 31, 1999. The decrease resulted primarily
from decreased sales of ARGUS data encryption products to the U.S. Army Corps
of Engineers.     
   
   License and service gross margin. License and service gross margin increased
as a percentage of its revenue from 43% during the three months ended March 31,
1998 to 73% during the three months ended March 31, 1999. The increase resulted
primarily from $369,000 of revenue related to the Forte project; all costs
related to the Forte project are included in research and development expenses.
       
   Selling, general and administrative expenses. Selling, general and
administrative expenses increased 32% from $662,000 during the three months
ended March 31, 1998 to $871,000 during the three months ended March 31, 1999.
As a percentage of revenue, selling, general and administrative expenses
increased from 40% during the three months ended March 31, 1998 to 62% during
the three months ended March 31, 1999. Selling, general and administrative
expenses increased primarily due to increased staffing to support business
expansion and increased professional fees.     
   
   Research and development expenses. Research and development expenses
increased 124% from $341,000 during the three months ended March 31, 1998 to
$765,000 during the three months     
 
                                       31

ended March 31, 1999. The increase was 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, and increased staffing to
support research and development efforts including the Forte project. As a
percentage of revenue, research and development expenses increased from 21%
during the three months ended March 31, 1998 to 54% during the three months
ended March 31, 1999. The increase reflected our continued investment in
research and development of future products and services coupled with the
reduction in revenue described above.     
   
   Interest expense, net. Interest expense, net increased slightly from
$108,000 during the three months ended March 31, 1998 to $109,000 during the
three months ended March 31, 1999. The average borrowings required for
operations were comparable during the three months ended March 31, 1998 and
1999.     
   
   Income taxes. Before 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 a credit of $51,000 and $9,000 for the
three months ended March 31, 1998 and 1999 as a result of losses from
operations.     
   
   Backlog. At March 31, 1999, Litronic had total backlog of $299,000,
including $227,000 attributable to the National Security Agency. Backlog
represents signed purchase orders received but not filled and, in the case of
the $227,000 attributable to the National Security Agency, funding of future
research and development costs. At March 31, 1998, we had total backlog of
$626,000, including $147,000 attributable to the U.S. Army Corps of Engineers
and $388,000 attributable to the National Security Agency.

   Total revenue. Total revenue decreased 45%, from $18.0 million during the
three months ended March 31, 1998 to $9.9 million during the three months ended
March 31, 1999. During the three months ended March 31, 1998 and 1999, Pulsar
derived 16% and 18% of its revenue from sales to the U.S. Immigration and
Naturalization Service. Total revenue to federal government agencies declined
33% from $14.1 million during the three months ended March 31, 1998 to $9.4
million during the three months ended March 31, 1999. This decrease is
attributable primarily to the federal government's reallocation of budget
dollars from hardware and software procurements to resolving year 2000 issues.
       
   Product revenue. Product revenue declined 43% from $16.8 million during the
three months ended March 31, 1998 to $9.6 million during the three months ended
March 31, 1999. This decrease is primarily attributable to the following
factors:     
     
  .  In 1997, Pulsar made a strategic decision to eliminate its high volume,
     low margin Federal Systems Integration, or FSI, program activities,
     which accounted for 13% of its product revenue during the three months
     ended March 31, 1998 and was completely eliminated as of March 31, 1999.
     Sales under the FSI program were phased out due to the diminishing
     margins produced by these sales.     
 
 
                                       32
<PAGE>
 
     
  .  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 was $1.2 million during the three
     months ended March 31, 1998 and was eliminated during the three months
     ended March 31, 1999.     
     
  .  Commercial, state and local government revenue decreased by 59%, from
     $1.4 million during the three months ended March 31, 1998 to $569,000
     during the three months ended March 31, 1999. This decrease is primarily
     attributable to the loss of a contract with Montgomery County, Maryland,
     and the closing of Pulsar's Atlanta sales office.     
     
  .  Revenue from the General Services Administration, or GSA, schedule
     contract and National Institutes of Health, or NIH, schedule contract
     declined 25% from $12.0 million during the three months ended March 31,
     1998 to $9.0 million during the three months ended March 31, 1999. This
     decrease is primarily attributable to the reallocation of government
     budget dollars from hardware and software procurements towards resolving
     year 2000 issues.     
   
   Service revenue. Service revenue declined by 69%, from $1.2 million during
the three months ended March 31, 1998 to $369,000 during the three months ended
March 31, 1999. This decrease is primarily attributable 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 total gross margins increased 25%, from
$546,000 during the three months ended March 31, 1998 to $684,000 during the
three months ended March 31, 1999.     
   
   Product gross margins. Pulsar's product gross margins increased from 2%
during the three months ended March 31, 1998 to 5% during the three months
ended March 31, 1999. The increase in gross product margins was primarily
attributable to not filing for rebate income during the three months ended
March 31, 1998. Additional factors attributable to increased gross product
margins include a reduction in FSI sales, which relate to lower margin product
sales, and Pulsar's successful bidding for higher margin product contracts.
       
   Service gross margin. Service gross margins increased from 41% during the
three months ended March 31, 1998 to 58% during the three months ended March
31, 1999. This increase is primarily attributable to Pulsar obtaining higher
margin contract work with Prince George's County and the loss of lower margin
contract work with the U.S. Department of Education and the Naval Research Lab
contract.     
   
   Selling, general and administrative expenses. Selling, general and
administrative expenses decreased 11% from $2.3 million during the three months
ended March 31, 1998 to $2.0 million during the three months ended March 31,
1999. The decrease was primarily attributable to a reduction in administrative
and sales staffing and rent expense partially offset by one-time fees of
approximately $450,000 associated with the acquisition of Pulsar by Litronic.
Bad debt expense increased from $75,000 during the three months ended March 31,
1998 to $165,000 during the three months ended March 31, 1999. The bad debt
expense for the three month periods ended March 31, 1998 and 1999 was related
to a reserve for the allowance for doubtful accounts against rebates receivable
and accounts receivable.     
   
   Interest expense. Interest expense decreased 32%, from $706,000 during the
three months ended March 31, 1998 to $478,000 during the three months ended
March 31, 1999. This is primarily attributable to a significant decrease in
Pulsar's average daily borrowings during the three months ended March 31, 1998
compared to the three months ended March 31, 1999.     
 
 
                                       33

   Interest income. Interest income decreased 90% from $200,000 during the
three months ended March 31, 1998 to $20,000 during the three months ended
March 31, 1999. The decrease is primarily attributable to the decrease in
interest recognized on the cash surrender value of life insurance policies.

   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.
   
   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 CEFMS contract. 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 revenue 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.
 
                                       34

   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 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 nonrecurring bonuses of $1.0 million 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. 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 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. In the case of the $596,000
attributable to the National Security Agency, backlog represents 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 was 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 GSA schedule revenue and NIH
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 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
     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
 
                                       36
<PAGE>
 
        
     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 instead 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.
   
   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 was
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.     
   
   The charge for obsolete inventory during the year ended December 31, 1998
was $344,000. Pulsar was unable to separately quantify the amount of expense
for obsolete inventory during the year ended December 31, 1997. This was due
to Pulsar's former practice of making one year-end reconciling adjustment to
the general ledger to adjust inventory for obsolescence and shrinkage and
differences between the physical inventory count and the general ledger
inventory balance. Since January 1, 1998, Pulsar has implemented a monthly
physical inventory reconciliation and a year-end reconciliation procedure to
separately account for obsolete inventory and differences in the physical
inventory and the general ledger inventory balance. Pulsar's historical year-
end reconciliation process ensured that inventory was stated accurately based
on physical count at each year-end and was not carried over from prior years.
    
   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 $13.3 million during the year

<PAGE>
 
   
ended December 31, 1998. The increase from 1996 to 1997 was attributable
primarily to bad debt expense associated with accounts receivable and notes
receivable. 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 $4.6
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 in the amount of $3.9 million and commercial loans
outside of the normal course of business that were deemed uncollectible in the
amount of $702,000. Bad debt expense in 1998 was incurred from commercial
clients who did not meet their obligations in the amount of $1.8 million and
rebate receivables that expired because they were incomplete or not collected
on a timely basis in the amount of $1.6 million. Additionally, 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
 
  .  establishing a collections staff to follow-up on payments related to
     rebates.
   
   Notes receivable--related parties. Pulsar had previously assigned two notes
receivable from third parties to a related party in the aggregate principal
amount of $623,000. These notes receivable were assigned back to Pulsar in
December 1997. The notes and accrued interest were determined to be
uncollectible after pursuing legal action to collect and written off as bad
debt expense in the year ended December 31, 1997.     
   
   The provision for notes receivable-related parties of $655,000 for the year
ended December 31, 1998 relates to a note due from a company owned by a
relative of the shareholders of Pulsar. The note is payable upon the sale of
the related party's real estate asset. During 1998 the related party
experienced financial difficulties as a result of its commercial real estate
operations. Based upon the related party's cash flows and decline in its
financial condition, Pulsar determined that the note had become impaired. The
amount of the impairment was determined in accordance with Statement of
Financial Accounting Standards No. 114, and the note was fully reserved as of
December 31, 1998.     
 
   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 32
     positions from January 30, 1998 to May 1, 1999; and     
 
  .  relocating to less expensive office space beginning October 1, 1998,
     thus decreasing monthly rent expense from $45,000 to $11,500.
 
                                       38
<PAGE>
 
   
   Costs incurred in 1998 to achieve these cost reductions included $24,000 in
severance fees and $750,000 in lease termination fees.     
   
   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, IBM Global. 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 decreased were 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 $13.5
million as of March 31, 1999.     
   
   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 substantially all of our personal and real property as
     collateral; and     
     
  .  a cap on our borrowings equal to 85% of our eligible accounts receivable
     plus the lesser of (a) 50% of the value of our eligible on-hand
     inventory or (b) $1.0 million.     
   
   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 and an
anticipated increase in rent expense for our California operation of $400,000
per year following our anticipated relocation of our California headquarters.
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
 
                                       39
<PAGE>
 
   
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 three months ended March 31, 1999, cash used in operations for
Litronic was $866,000, primarily due to a net loss of $973,000 and an increase
in other current assets of $599,000. These were partially offset by a decrease
in accounts receivable of $88,000 due to improved collections in 1999 and an
increase in accounts payable of $455,000.     
   
   During the three months ended March 31, 1999, cash provided by financing
activities was $594,000, consisting primarily of borrowings of $1.1 million
under the revolving note payable to a bank and $750,000 under the long-term
notes payable, partially offset by repayments of $1.3 million under the
revolving note payable to a bank.     
   
   Litronic's capital expenditures, including computer equipment, test
equipment and furniture and fixtures, were $69,000 during the three months
ended March 31, 1999. Litronic's capital expenditures were funded through cash
generated from operations and through its secured revolving credit line and
borrowing from its principal shareholders.     
   
   As of March 31, 1999, Litronic had an aggregate of $5.9 million outstanding
under various promissory notes to BYL Bank Group at a fixed annual interest
rate of 6.6%. These notes are due upon the earlier of July 31, 2000 or a change
of control of Litronic Industries and are personally guaranteed by Kris Shah
and secured by personal assets pledged by Mr. Shah. We intend to use proceeds
from this offering to repay the indebtedness under these notes.     
   
   In addition, we intend to use proceeds from this offering to repay in full
the outstanding balance under Litronic's $2.5 million line of credit facility
with Fidelity Funding Inc. in the approximate amount of $450,000. This facility
expires in February 2000 and is personally guaranteed by Mr. Shah.     
   
 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 IBM Global 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 IBM Global through the closing of this offering and expects to
repay IBM Global in full following the closing of this offering.     
   
   Total cash provided for the three months ended March 31, 1999 was $89,000.
Pulsar's cash provided from operations for the three months ended March 31,
1999 was $2.9 million. This primarily resulted from collections of accounts
receivable of $4.2 million, and an increase in accrued liabilities of $551,000,
offset by a net loss of $1.8 million. The increase in accrued liabilities was
primarily attributable to accrued professional fees associated with the
acquisition of Pulsar by     
 
                                       40
<PAGE>
 
   
Litronic. Cash used in financing activities resulted primarily from repayments
of our line of credit for $2.2 million and repayments of vendor notes payable
for $587,000.     
   
   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 $18.4 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 $8.1
million, including a non-cash bad debt expense of $3.4 million. Inventory
decreased as a result of a change in business practices from carrying inventory
to anticipate customer requests to a just-in-time method of inventory.     
   
   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 IBM
Global, 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. Proceeds from loans from cash surrender value of life insurance net
of premium payments were $1.2 million.     
   
   During the year ended December 31, 1998 and the three months ended March 31,
1999, Pulsar repaid a total of approximately $1.0 million outstanding under its
term loan from Wilmington Trust Company which bears interest at the prime rate
in effect from time to time and matures in December 2002. On May 5, 1999, this
loan was reduced by an additional $543,000, leaving a balance due of
approximately $3.5 million. This debt is personally guaranteed by William W.
Davis, Sr. and Lillian A. Davis and is secured by property pledged by a family
member of Mr. Davis. We intend to use proceeds from this offering to repay the
balance of this indebtedness in full.     
   
   During the year ended December 31, 1998 and the three months ended March 31,
1999, Pulsar also converted $5.0 million in accounts payable to notes payable
due to negotiated agreements with vendors. As of March 31, 1999, $3.3 million
of these notes payable remained outstanding. We intend to use proceeds from
this offering to repay this balance.     
   
   In addition, since January 1, 1998, lawsuits were filed against Pulsar by
trade vendors and a local government agency seeking to collect an aggregate of
approximately $1.8 million, plus interest, attorney's fees and costs. Pulsar
incurred $173,000 and $102,000 of interest expense and penalties during the
year ended December 31, 1998 and the three months ended March 31, 1999 relating
to the amount due to these trade creditors and government agency. Pulsar has
entered into settlements relating to these claims under which it has paid a
total of $760,000, including interest of $30,000. Under these settlements,
Pulsar is required to pay an additional $815,000, including interest of
$54,000, all of which is due during 1999. The aggregate amount of claims that
have been filed but not settled is approximately $288,000. We have allocated
$1.1 million of the net proceeds of this offering to pay the amounts due under
the settlements, as well as anticipated amounts to pay as-yet-unsettled claims.
       
   Additionally, Pulsar has approximately $3.1 million of accounts payable
balances which are more than 90 days overdue. We expect to use cash from
operations to fund these obligations to the extent we are not able to negotiate
extended payment arrangements. If these funds prove insufficient, we may use a
portion of the proceeds from this offering allocated to working capital to
satisfy these obligations.     
 
                                       41

   Pulsar funded its operations during the year ended December 31, 1998 through
its financing agreement with IBM Global. Under this agreement, Pulsar purchases
hardware and software from authorized suppliers and finances the purchases
through IBM Global. The agreement provided 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, which
was reduced to $8.0 million as of April 30, 1999. As of March 31, 1999, $7.2
million was outstanding under the line. The line of credit allows Pulsar to
finance up to 85% of its eligible accounts receivable 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, and secured by $1.4 million of the
personal assets of, Mr. Davis and Ms. Davis. We intend to use $1.4 million of
the proceeds from this offering to reduce amounts outstanding under this credit
line and eliminate the pledge of assets by Mr. Davis and Ms. Davis.     
   
   IBM Global has agreed to forbear Pulsar's violations of financial covenants
in the IBM Global financing agreement in exchange for Pulsar's agreement to pay
to IBM Global, 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 IBM Global by paying $650,000 to it
upon the closing of this offering.     
       
       
       
          
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, 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 and three months ended March 31,
1999, sales of Internet data security products, including NetSign, Pro File
Manager and CryptOS, accounted for 6% and 8% 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     
 
                                       42
<PAGE>
 
   
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 and three months ended March 31,
1999, on a pro forma combined basis, product reselling accounted for 89% and
84% of our revenue and license and service revenue accounted for 6% and 8% 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, only one of our customers, the U.S.
Immigration and Naturalization Service, has accounted for 10% or more of our
revenue, accounting for 21% of combined revenue during the year ended December
31, 1998 and 16% of combined revenue during the three months ended March 31,
1999. Sales to U.S. government agencies accounted for approximately 90% of our
pro forma combined revenue for the year ended December 31, 1998 and 86% during
the three months ended March 31, 1999.     
   
 Gross margins     
   
   During the year ended December 31, 1998 and three months ended March 31,
1999, Litronic's data security products had gross margins of 46% and 43% and
Pulsar's product reselling activities had gross margins of 7% and 5%. Pulsar
recently shifted its product reselling focus toward higher margin computer and
network security products, including intrusion detection software and
firewalls, which are custom designed configurations installed into a network to
prevent unauthorized access from outside the network. 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
and 67% for the three months ended March 31, 1999 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. In addition, as a combined entity, we
expect to consolidate 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.     
 
                                       43
<PAGE>
 
   
   Our sales and marketing expenses are generally incurred in advance of
associated revenue and we expect these expenses to increase both as a
percentage of revenue as well as in amount. These measures could adversely
affect our operating income.     
   
   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 $5.0 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 $33.4 million, or 56%, of our pro forma
combined, as adjusted, assets as of March 31, 1999, consisted of intangible
assets arising from the acquisition. This amount represents goodwill and other
intangibles, which will be amortized over 10- to 15-year periods 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.     
 
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.
 
                                       44
<PAGE>
 
 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 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 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 length of our customer commitments;     
       
  .  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.
   
   In addition, 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. 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.     
   
   As a result, comparisons of quarterly results may not be meaningful and
should not be relied upon, nor will they necessarily reflect on future
performance. Fluctuations in quarterly operating results may adversely affect
the trading price of our common stock if our operating results are below the
expectations of public market analysts and investors.     
 
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.
 
                                       46

   In March 1998, the American Institute of Certified Public Accountants issued
Statement of Position 98-1, Accounting for the Costs of Computer Software
Developed 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 the Internet and Internet protocol-based 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
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 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 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
 
                                       48
<PAGE>
 
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 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.
     
  .  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 and Internet protocol-based 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
 
                                       49
<PAGE>
 
   
persons. Digital cryptography is performed using a combination of symmetric
ciphers and asymmetric ciphers to achieve each of the basic data security
elements of identification and authentication, confidentiality, integrity and
non-repudiation. Symmetric ciphers are commonly referred to as symmetric-key or
secret-key cryptography and asymmetric ciphers are commonly referred to as
asymmetric-key or public-key cryptography.     
   
   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.     
   
 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.
 
                                       50
<PAGE>
 
   
   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 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 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 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-based 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 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
 
                                       52
<PAGE>
 
     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 high-level 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
        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 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
 
                                       53
<PAGE>
 
     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 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--our security products are designed to use different suites
     of algorithms depending upon the application requirements, for example,
     military or banking and finance.     
     
  .  platforms--our security products may be used with many different
     computer types and operating systems, for example, Windows, UNIX, and
     MacIntosh.     
     
  .  applications--our security products may be used with various software
     applications, for example, e-mail, e-commerce, database systems or word
     processors.     
     
  .  tokens--our 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, or ISA, and
peripheral component interconnect, or 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.     
 
 Internet application software
   
   NetSign and NetSign PRO. These products are software adapters that integrate
smartcards and digital certificate technology to enhance security in software
systems designed to provide electronic commerce, e-mail, Internet access, file
access and world-wide-web browsers such as Netscape     
 
                                       54
<PAGE>
 
Communicator and Microsoft Explorer. NetSign and NetSign PRO software products
are bundled with a smartcard reader/writer and smartcards. NetSign PRO has the
added security feature of file encryption capabilities and other security
utilities.
   
   ProFile Manager. ProFile Manager is a complete, stand-alone, PKI lifecycle
management solution of token-based security systems from initialization to
secure archive and recovery. For the recovery of token-based information,
ProFile Manager provides an optional integration with a secured database of
private keys and other user identification information and the use of third-
party certificate authorities. ProFile Manager integrates with NetSign, NetSign
PRO and other token-enabled products to provide a complete solution for an
enterprise's security needs, including secure Internet access, digitally signed
and encrypted 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, or 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.     
   
 Security tokens     
   
   ISO smartcards. We offer a family of off-the-shelf International Standards
Organization, or 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 an
ultra fast 32-bit 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.     
 
 
                                       55
<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, or
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 for both internal and external application, that
interface via various ports such as SCSI, ISA bus, PCI bus, Universal Serial
Bus and parallel port. 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
   
   Pulsar has developed and we intend to 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     
 
                                       56

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
   
   Through our Pulsar operations, we will 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.

   Our newly acquired Pulsar staff has specific expertise in the following
areas of networking systems:     
     
  .  Internet enterprise network consulting: As computer networks become more
     complex the assistance of knowledgeable network professionals is
     critical for maximum performance. Our network consulting staff will be
     able to help organizations realize their business goals and objectives.
            
  .  Network management: Today's network managers must cope with a maze of
     network protocols, configuration options and computing platforms. Our
     network management staff will be able to support information systems
     departments in their effort to manage these diverse networking platforms
     by assisting with the training, configuration and implementation of
     network management systems and products.     
     
  .  Remote computing: As companies increasingly decentralize their business
     functions, they must consider connectivity options for remote users. Our
     remote computing team will be able to effectively deliver the most cost-
     effective and reliable methods to allow users access to corporate
     systems. Whether a business requires dial-in dial-out capability or
     Internet access, we will be able to provide a complete solution that
     incorporates training and implementation.     
 
Product reselling
   
   Historically, a substantial portion of Pulsar's product resale revenues was
derived from sales of low-end, low-margin computer and network security
products. Pulsar has, however, increasingly been shifting its 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.     
 
   Examples of these high-end, high-margin computer and network security
products include:
 
  .  Intrusion detection software--used to detect unauthorized access, and
     identify the source of the access, within a network. These products
     include Net Ranger and PIX.
     
  .  Firewalls--custom designed software and hardware configurations
     installed into a network to prevent unauthorized access from outside the
     network. Pulsar offers high-end firewall     
 
                                       58
<PAGE>
 
     solutions from leading vendors, including Lucent Technologies, Inc.,
     Network Associates, Inc., Cyberguard Corporation, Cisco Systems, Inc.,
     and Bay Networks, Inc.
     
  .  Network hardware components--servers, routers, hubs and switches
     configured to the customer's networking requirements. Pulsar offers
     components manufactured by leading vendors, including Cisco Systems,
     Inc., Bay Networks, Inc., Hewlett-Packard Company, Bell Computers,
     International Business Machines Corp., Lucent Technologies, Inc. and Sun
     MicroSystems, Inc.     
 
  .  Anti-virus software--high-end software programs installed at server
     level to prevent viruses from entering the network, and client-level
     software programs to prevent virus corruption to client-server
     applications.
 
  .  Virtual private networks--a secure point-to-point connection over the
     Internet through which encrypted messages can be transmitted to protect
     communications between remote locations.
     
  .  Data security products--access control products, including third-party
     APIs, device drivers, token reader/writers and tokens, and, following
     this offering, those of Litronic.     
   
   We believe that focusing on these high-end, high-margin products will lead
to higher rates of customer retention. This is because of the complex nature
of the product configurations, which results in customers' making purchasing
decisions based on factors other than simply the lowest price. Further,
because the products are highly customized, we will not be required to make
substantial investments in inventory.     
   
   After the offering, we will, where appropriate, also include our own data
security products within our product configuration solutions.     
 
Customers
   
   Our customers represent a wide range of commercial enterprises, including
financial, telecommunications, healthcare and information service companies,
airlines, automobile manufacturers, as well as federal, state, local and
foreign government agencies. We believe significant cross-marketing
opportunities exist with the integration of Pulsar's customer base of over 100
federal agencies and over 40 commercial and state and local government
customers.     
   
   Following the Pulsar acquisition, our combined customer base will include:
    
  . Netscape Communications                 . Federal National Mortgage
    Corporation                               Association

                                              Investigation
  . Lucent Technologies, Inc.     
 
Customer service and support
   
   We believe that customer service and support is critical to retaining
existing customers and attracting prospective customers. Our combined customer
service and support staff consists of 16     
 
                                      59
<PAGE>
 
persons, including engineers and technical support personnel, and works closely
with customers and prospective customers to provide comprehensive service and
support for our products and systems.
   
   We provide enhanced customer support by maintaining a toll-free customer
service line and a two-tier support system. The first tier consists of help
desk support personnel responding to phone and mail requests for service and
accessing customer information and a problem database for solutions. For more
sophisticated problems, second tier support is provided by systems technical
support staff.     
 
Sales and marketing
 
   We market our products and services through the Internet, our direct sales
forces, third-party distribution channels, including systems-integrators,
value-added resellers and original equipment manufacturers, strategic alliances
and international distributors. We intend to devote significant resources to
marketing and business development activities to expand our business to
additional distribution channels.
 
 Direct marketing effort
   
   As of May 1, 1999, on a combined basis, 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 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;
 
 
                                       60
<PAGE>
 
  . jointly develop products and services;
 
  . conduct joint research and development efforts;
 
  . jointly conduct proposals and presentations for products and services and
   reseller arrangements.
 
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, which we
     are embedding in our next generation PKI cards, the Forte PKIcard.
     
  .  Keytronic--We and Keytronic sell versions of NetSign bundled with the
     Keytronic keyboard, which currently incorporate an integrated PKI
     card/smartcard reader and will incorporate our Forte PKIcard reader.
         
  .  RSA Data Security--we have a distribution license agreement with RSA
     which allows us to incorporate RSA technology into our products.
 
  .  Datacard--Datacard serves as an official distributor of our PKI card
     products and integrates our NetSign and ProFile Manager and CryptOS
     products into our PKI card printers.
 
  .  SCM Microsystems, Inc.--we engage in cooperative marketing and selling
     of SCM hardware produced with our software.
 
   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 GSA schedule contracts, blanket purchase agreements and
bidding procedures, have been developed to access this market.     
   
   The GSA, 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     
 
                                       61
<PAGE>
 
   
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 is 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 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 our business,
products and services. We are currently 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 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.
 
                                       63
<PAGE>
 
   
   As of May 1, 1999, our research and development staff consisted of 29
employees, of whom 26 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 $5.0 million of the proceeds of this offering for research and
development activities.     
 
Competition
 
   We compete in numerous markets, including;
 
   .  Internet and intranet electronic security;
 
  .  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
 
                                       64
<PAGE>
 
   .  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
 
                                       65
<PAGE>
 
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.
   
   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.     
   
   We own or have rights to trademarks and trade names that we use in
conjunction with the sale and licensing of our products. The following
trademarks mentioned in this prospectus are our registered trademarks: Cyper
Server and CryptOS. We also own the trade names Litronic, Pulsar, Pulsar Data
and Pulsar Data Systems, Inc. We have applied for the trademarks Pro File
Manager, Netsign, Netsign Pro, Forte PKIcard and Maestro. All other trademarks
or trade names referred to in this prospectus are the property of their
respective owners.     
 
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.

development, legal and administration. After the closing of this offering, we
expect to integrate Pulsar's workforce.
 
   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. We are currently negotiating and
expect to enter into a lease for a new headquarters facility in California of
approximately 40,000 square feet. This would replace our current headquarters
which we would attempt to sublet. We expect our new facility would have an
annual rent of approximately $600,000 and a lease term ranging from seven to
ten years. 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, a local government agency has filed a claim for back
taxes owed by Pulsar. Following is a summary of these lawsuits:

   The aggregate amount claimed under these lawsuits was approximately $1.8
million, plus interest, attorney's fees and costs. Pulsar has entered into
settlements including stipulated judgments covering some of the lawsuits. As of
May 5, 1999, Pulsar has paid approximately $760,000 under those settlements. As
of May 5, 1999, the aggregate amount Pulsar owes on claims that have been filed
and settled is approximately $815,000. The aggregate amount of claims,
excluding interest, attorney's fees and costs, that have been filed but not
settled is approximately $288,000.     
   
   We intend to use the net proceeds from this offering to resolve and pay
these claims and settlements. See "Use of Proceeds" and "Management's
Discussion and Analysis of Financial Condition and Results of Operations."     
 
   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 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.

Employment agreements
   
 General     
   
   Kris Shah and William Davis have each entered into a two-year employment
agreement with Litronic, effective as of the date of this prospectus. 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. 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 $1.0 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 and other
intangibles 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
 
    .  breached the terms of the employee agreement.
 
  .  Additionally, we can terminate the agreement upon the employee's:
 
    .  death;
 
                                       73
<PAGE>
 
    .  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     
 
   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.

   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 from 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 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.

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 $10.00 per share. As a result of the Pulsar acquisition, Pulsar will
become a wholly-owned subsidiary of Litronic and William Davis and Lillian
Davis will become principal stockholders of Litronic.     
       
       
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.     
 
   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
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
 
                                       77
<PAGE>
 
   
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. On April 30, 1999, Davis Holding, Inc. sold the Lanham property.
The proceeds from the sale of the building went into an escrow account with
Wilmington Trust Company. On May 5, 1999, Wilmington Trust offset the Davis
Holding, Inc. note of $543,000, plus interest of $13,000 against the
outstanding Pulsar loan balance with Wilmington Trust Company. A determination
was made on the remaining $804,000 note that there were not sufficient assets
within Davis Holding, Inc. to repay the outstanding notes payable in the
future. Therefore, the remaining receivable was completely reserved as of
December 31, 1998.     
   
   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 $22.0 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 $5.2 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 $1.0 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 March 31, 1999, $424,000 was
outstanding under this facility. We intend to repay the outstanding
indebtedness under this credit facility out of the proceeds from this offering.
This will release Mr. Shah's guarantee.     
   
   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 $1.0 million, which was
personally guaranteed by 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
 
                                       78
<PAGE>
 
   
1997, we made a cash distribution of $9.5 million to our stockholders.
Subsequently, as discussed below, we distributed the capital stock and net
assets of KRDS 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 IBM Global which provides that Pulsar can finance
purchases of products through IBM Global. 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 of 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. This will release Mr. Davis' guarantee and
the assets pledged by him.     
   
   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
consisting of $8.5 million of cash.     
   
   During the year ended December 31, 1998 and the three months ended March 31,
1999, we executed promissory notes aggregating $5.9 million in favor of BYL
Bank Group at a fixed annual rate of interest of 6.6%. The notes are 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 $95,000 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, $.01 par value per share and 5,000,000
shares of preferred stock, $.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.     
       
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     
 
                                       79
<PAGE>
 
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 $.01 per share.
The board may issue the stock in one or more series and may 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 board may authorize the issuance of preferred stock with
voting or conversion rights that could adversely affect the voting power or
other rights of the holders of the common stock. The issuance of preferred
stock, while providing flexibility in connection with possible acquisitions and
other corporate purposes, could have the effect of delaying, deferring or
preventing a change in control and may adversely affect the market price of the
common stock and the voting and other rights of the holders of common 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 granted the representatives of the
underwriters registration rights with respect to their warrants to purchase up
to 370,000 shares of our common stock.     
   
Anti-takeover provisions     
   
 Delaware General Corporation Law     
          
   Section 203 of the Delaware General Corporation Law 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 unless (a) before such date, our board of directors approved either
the business combination or the transaction which resulted in the stockholder
becoming an interested stockholder, (b) upon completion of the transaction
which resulted in the stockholder becoming an interested stockholder, the
interested stockholder owned at least 85% of our voting stock outstanding at
the time the transaction commenced, excluding select shares, or (c) on or after
that date, the business combination is approved by our board of directors and
by the affirmative vote of at least 66% of our outstanding voting stock which
is not owned by the 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.     
   
   Our certificate of incorporation does not exclude Litronic from the
restrictions imposed under Section 203 of the Delaware General Corporation Law.
We expect the provisions of Section 203 of the Delaware General Corporation Law
may encourage companies interested in acquiring us to negotiate in advance with
the board, since the stockholder approval requirement would be avoided if a
majority of the directors then in office approve, prior to the time the
stockholder becomes an interested stockholder, either the business combination
or the transaction which results in the stockholder becoming an interested
stockholder.     
 
                                       80
<PAGE>
 
   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.
   
Charter and bylaw provisions     
   
   Our certificate of incorporation and bylaws divide the board into three
classes as nearly equal in size as possible with staggered three-year terms.
The classification of the board could make it more difficult for a third party
to acquire, or discourage a third party from acquiring, control of us. In
addition, our certificate of incorporation provides that any action required or
permitted to be taken by our stockholders at an annual meeting or a special
meeting may be taken only if it is properly brought before the meeting, and may
not be taken by written action instead of a meeting. Our bylaws provide that
special stockholders' meetings may be called only by the board, the president,
or by one or more stockholders holding shares in the aggregate entitled to cast
not less than 10% of the votes at that meeting.     
   
Delaware law and charter and bylaw provisions limiting liability of officers
and directors     
 
   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 American Stock
Transfer Company, 40 Wall Street, New York, New York 10005.     
 
                        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 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
9,740,631 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     
 
                                       81
<PAGE>
 
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 commencing twelve months after the date of this prospectus.
 
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 97,400 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.
 
 
                                      82
<PAGE>
 
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
completion of this offering.
 
Rule 701
 
   In general, under Rule 701 of the Securities Act as currently in effect, any
of our employees, consultants or advisors who purchases securities, including
options, from us before the date of this prospectus through our stock option
plans or through some other written agreement is eligible to resell those
shares, including shares issued upon the exercise of options, 90 days after the
effective date of this offering in reliance on Rule 144, but without compliance
with the holding period, information and volume restrictions contained in Rule
144.

   Other than shares offered through the over-allotment option, the
underwriters are committed to purchase and pay for all of the shares of common
stock offered by this prospectus, 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 listed 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 555,000 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     
 
                                       83
<PAGE>
 
   
total underwriting discounts and commissions would be $    and the total
proceeds paid to us, before payment of the expenses of this offering, 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
$2.8 million.     
 
   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% 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 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 $370, warrants to purchase up to 370,000
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' warrants contain a
cashless exercise provision. We have agreed that, upon the request of the
holders of a majority of the representatives' 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.

   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 or maintain the market price of the common stock,
which may be higher than the price that might have prevailed in the open
market without these activities, 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.

(WHEN THE REORGANIZATION AS DESCRIBED IN NOTE 1 OF THE ACCOMPANYING
CONSOLIDATED FINANCIAL STATEMENTS HAS BEEN CONSUMMATED, WE WILL BE IN A
POSITION TO RENDER THE FOLLOWING OPINION.)

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
 
                           December 31, 1997 and 1998
                     (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.
   
   In the opinion of the Company, the accompanying unaudited condensed
consolidated financial statements contain all adjustments (which are normal
recurring accruals) necessary to present fairly the financial position as of
March 31, 1999, and the consolidated statements of operations, shareholders'
deficiency and cash flows for the three months ended March 31, 1998 and 1999.
The results of operations for the three months ended March 31, 1999 are not
necessarily indicative of the results to be expected for the entire fiscal
year.     
 
   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 stock acquisition agreement with
Pulsar Data Systems, Inc. to be effected simultaneously with the Offering. This
acquisition 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.
 
   Pro Forma Presentation
 
   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

                                 AND SUBSIDIARY
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
 
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, and for the three months ended March 31, 1998 and 1999, 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 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 for the year ended December 31, 1998
and the three months ended March 31, 1999 is $398 and $369 (unaudited),
respectively, related to a contract with the National Security Agency (NSA).
The Company is designing a microprocessor meeting certain minimum
specifications under a contract with the NSA. The Company has contracted with
others to perform certain aspects of the project. All related project costs are
expensed as research and development as incurred. No other funds received for
research and development projects were recorded during any of the periods
presented. The amounts received from the NSA are not refundable regardless of
the results of the 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.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
 
   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
 
   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
and March 31, 1999 (unaudited), 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

                                 AND SUBSIDIARY
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
   
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. The provision (benefit) for state income taxes
was ($51) and ($9) for continuing operations for the three months ended March
31, 1998 and 1999, respectively (unaudited).     
 
   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.
 
   Estimates
 
   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 not
to exceed $45,400 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.

(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

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
 
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
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. The Company had sales to two customers which
represented 39% (unaudited) and 27% (unaudited), respectively, of total revenue
for the three months ended March 31, 1999. No other customers accounted for
more than 10% of net revenues in 1996, 1997 or 1998. Trade accounts receivable
aggregated $709, $493 and $388 (unaudited) from the aforementioned major
customers as of December 31, 1997 and 1998, and March 31, 1999, respectively.

   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.

   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.

   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

$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.

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 $8,141,000 in 1998 and has a net capital deficiency of $9,951,000
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 schedule do not include any
adjustments that might result from the outcome of this uncertainty.

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 and
financial statement schedule do not include any adjustments that might result
from the outcome of this uncertainty.

                         NOTES TO FINANCIAL STATEMENTS
 
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 from the 8(a)
program in June 1997 in anticipation of graduation.     
 
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.
   
   Deferred governmental agency contract costs and revenue: Deferred costs and
revenue from contracts with governmental agencies represent costs incurred and
accounts receivable billed as of year end, for which an acceptance period has
not expired. The agencies involved have negotiated acceptance periods from
seven to thirty days from delivery of the product. General and administrative
expenses related to other costs that were deferred were included as a component
of deferred costs. All equipment subject to the acceptance period at December
31, 1996 was subsequently accepted by the government. Substantially all
contracts with acceptance periods terminated during the year ended December 31,
1997.     
 
   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 purchased 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. Cost consists of
the direct cost of purchased inventory.     
 
   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.     
 
   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.

                  NOTES TO FINANCIAL STATEMENTS--(Continued)
   
   Earnings (loss) per share: The computations of basic and diluted earnings
(loss) per common share are based upon the weighted average number of common
shares outstanding during the year. There were no potentially dilutive
securities for any period presented.     
   
   Unaudited condensed interim information: The accompanying unaudited
condensed financial statements contain all adjustments, which are normal
recurring accruals, necessary to present fairly the financial position as of
March 31, 1999 and the statements of operations, stockholders' equity
(deficit) and cash flows for the three months ended March 31, 1998 and 1999.
The results of operations for the three months ended March 31, 1999 are not
necessarily indicative of the results to be expected for the entire fiscal
year.

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 and March 31, 1999, was $1,416,000, $216,000 and $224,000 (unaudited),
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 and interest 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. During 1998, the related party experienced financial difficulties as
a result of its commercial real estate operations. Based upon the related
party's cash flows and decline in its financial condition the Company
determined that one of the notes had become impaired and recorded a bad debt
expense of $655,000 and reversed $149,000 of interest income recorded on the
note in 1998. The repayment of the notes is dependent upon the sale of the
related party's real estate assets.     
          
   On April 1, 1999, the related party defaulted on both notes by not making
the scheduled interest payments in accordance with the note agreements. As of
April 30, 1999, the related party sold one of the properties. The note for
$543,000 was repaid on May 5, 1999 through the reduction of the note payable-
financial institution. In connection with the payment of a portion of the note
payable-financial institution, the financial institution released the Company
from its guarantee obligation on the related party's remaining liabilities
(unaudited).     
 
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 and March 31, 1999 (unaudited) 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 was 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 was reduced to $8,000,000. The
forbearance agreement expires on the date of the anticipated acquisition and
initial public offering (Note 14).

Note 11. Leasing Arrangements
   
   In January 1996, the Company entered into a lease with a related party for
office space, which was due to expire in December 2000. In September 1998 this
lease was terminated and the Company paid a $750,000 termination fee to the
related party. The fee was offset against notes receivable owed from the
related party. Deposits and other assets includes a deposit to be refunded from
the related party of approximately $87,000. The Company has leased other office
and warehouse space under separate lease agreements expiring through September
2003. Rent expense was $1,690,000, $811,000, $1,252,000 and $51,000 (unaudited)
for the years ended December 31, 1996, 1997 and 1998 and for the three months
ended March 31, 1999, respectively. Lease payments for the year ended December
31, 1998 were offset against interest receivable and notes receivable from the
related party (see Note 5).     
 
   Future minimum rental payments required under these leasing arrangements as
of December 31, 1998 are as follows:

Note 12. Employee Retirement Plan
   
   The Company has adopted a retirement plan under Section 401(k) of the
Internal Revenue Code. The plan provides benefits to all employees who meet
certain age and service eligibility requirements. Under the terms of the plan,
the Company will match 50% of the first 6% of an employee's elective
contribution. Company contributions for the years ended December 31, 1996, 1997
and 1998 were $71,000, $66,000, and $28,000, respectively. The contribution for
the three months ended March 31, 1999 was $5,000 (unaudited).     
 
Note 13. Major Customers
   
   During the years ended December 31, 1996, 1997, and 1998 and the three
months ended March 31, 1999, 61%, 60%, 90% and 94% (unaudited), respectively,
of the Company's revenue was derived from contracts with

the Federal Government. The receivable balance for these contracts at December
31, 1997 and 1998 and March 31, 1999 was $19,075,000, $9,135,000 and $5,517,000
(unaudited), respectively.     
 
Note 14. Going Concern
   
   As shown in the accompanying financial statements, the Company incurred a
net operating loss of $11,016,000 and $8,141,000 for the years ended December
31, 1997, and 1998, respectively, and has a net capital deficiency of
$1,810,000 and $9,951,000 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
acquisition 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.
          
   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 reserved $50,000 which represents the
Company's estimate of the maximum amount of penalties that could be assessed.

Item 14. Indemnification of Directors and Officers
   
   Section 145 of the Delaware General Corporation Law 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 he 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 permits a
corporation to provide in its certificate of incorporation that a director of
the corporation shall not 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.     
 
                                      II-1
<PAGE>
 
   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 shareholders 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.

BlueStone Capital Partners, L.P.
Pacific Crest Securities Inc.
 as Representatives of the
 Several Underwriters named
 in Schedule A hereto
575 Fifth Avenue
New York, New York 10017

Dear Sirs:

     Litronic Inc., a Delaware corporation (the "Company"), proposes to issue
and sell to the underwriters (the "Underwriters") named in Schedule A to this
Underwriting Agreement (the "Agreement"), for whom BlueStone Capital Partners,
L.P. ("BlueStone") and Pacific Crest Securities Inc. are acting as
representatives (together, hereinafter referred to as the "Representatives"),
three million seven hundred thousand (3,700,000) shares of common stock, par
value $.01 per share (the "Offered Shares"), which Offered Shares are presently
authorized but unissued shares of the common stock, par value $.01 per share
(individually a "Common Share" and collectively the "Common Shares"), of the
Company. In addition, the Representatives, in order to cover over-allotments in
the sale of the Offered Shares, may purchase from the Company, for their own
accounts, up to an aggregate of five hundred fifty-five thousand (555,000)
Common Shares (the "Optional Shares"; the Offered Shares and the Optional Shares
are hereinafter sometimes collectively referred to as the "Shares"). The Shares
are described in the Registration Statement, as defined below. The Company also
proposes to issue and sell to the Representatives for their own accounts and/or
the accounts of their designees, warrants to purchase an aggregate of three
hundred and seventy thousand (370,000) Common Shares (the "Warrant Shares") at
an exercise price of $_____ [165% of the initial public offering price per
share] per Warrant Share (the "Representatives' 
     
<PAGE>

     
Warrants"), which sale will be consummated in accordance with the terms and
conditions of the form of Representatives' Warrant Agreement filed as an exhibit
to the Registration Statement.

     The Representatives hereby warrant to the Company that they have been
authorized by each of the Underwriters to enter into this Underwriting Agreement
on their behalf and to act for them in the manner herein provided.  The Company
hereby confirms its respective agreements with the Representatives and each of
the Underwriters, on whose behalf the Representatives are signing this
Agreement, as follows:

     1.   Purchase and Sale of Offered Shares. On the basis of the
representations and warranties herein contained, but subject to the terms and
conditions herein set forth, the Company hereby agrees to sell the Offered
Shares to the Underwriters, severally, and each Underwriter agrees, severally
and not jointly, to purchase from the Company, at a purchase price of $____ [93%
of the initial public offering price] per share, the number of Offered Shares
set forth opposite the name of such Underwriter in Schedule A attached hereto,
plus any additional Offered Shares which such Underwriter may become obligated
to purchase pursuant to the provisions of Section 10 hereof. The Underwriters
plan to offer the Offered Shares to the public at a public offering price of
$_____ per share.

     2.   Payment and Delivery.
          -------------------- 

          (a)  Payment for the Offered Shares will be made to the Company by
wire transfer against delivery of the Offered Shares to the Representatives.
Such payment and delivery will be made at 10:00 A.M. New York City time, on the
third business day following the Effective Date (the fourth business day
following the Effective Date in the event that trading of the Offered Shares
commences on the day following the Effective Date), the date and time of such
payment and delivery being herein called the "Closing Date." The certificates
representing the Offered Shares to be delivered will be in such denominations
and registered in such names as the Representatives may request not less than
two full business days prior to the Closing Date, and will be made available to
the Representatives for inspection, checking and packaging at the offices of
Continental Stock Transfer & Trust Company, the Company's transfer agent, at Two
Broadway, New York, New York 10004 not less than one full business day prior to
the Closing Date.

          (b)  On the Closing Date, the Company will sell the Representatives'
Warrants to the Representatives or to their designees (limited to officers and
partners of the Representatives and Underwriters). The Representatives' Warrants
will be in the form of, and in accordance with, the provisions of the     

                                      -2-

<PAGE>

     
Representatives' Warrant Agreement attached as an exhibit to the Registration
Statement, with such changes as the Representatives shall approve. The aggregate
purchase price for the Representatives' Warrants is $300. The Representatives'
Warrants will be restricted from sale, transfer, assignment or hypothecation for
a period of one year from the Effective Date, except to officers or partners of
the Representatives and Underwriters and members of the selling group and/or
their officers or partners. Payment for the Representatives' Warrants will be
made to the Company by check or checks payable to its order on the Closing Date
against delivery of the certificates representing the Representatives' Warrants.
The certificates representing the Representatives' Warrants will be in such

     3.   Option to Purchase Optional Shares.
          -----------------------------------

          (a)  On the basis of the representations and warranties and subject to
the terms and conditions set forth herein, for the purposes of covering any
overallotments in connection with the distribution and sale of the Offered
Shares as contemplated by the Prospectus as defined below, the Representatives
are hereby granted an option to purchase for their own accounts, and not as
representatives of the Underwriters, all or any part of the Optional Shares from
the Company. The purchase price to be paid for the Optional Shares will be the
same price per Optional Share as the price per Offered Share set forth in
Section 1 hereof. The option granted hereby may be exercised by the
Representatives as to all or any part of the Optional Shares at any time within
45 days after the Effective Date. The Representatives will not be under any
obligation to purchase any Optional Shares prior to the exercise of such option.

          (b)  The option granted hereby may be exercised by the Representatives
by giving oral notice to the Company, which must be confirmed by a letter, telex
or telegraph setting forth the number of Optional Shares to be purchased, the
date and time for delivery of and payment for the Optional Shares to be
purchased and stating that the Optional Shares referred to therein are to be
used for the purpose of covering over-allotments in connection with the
distribution and sale of the Offered Shares. If such notice is given prior to
the Closing Date, the date set forth therein for such delivery and payment will
not be earlier than either two full business days thereafter or the Closing
Date, whichever occurs later. If such notice is given on or after the Closing
Date, the date set forth therein for such delivery and payment will not be
earlier than two (2) full business days thereafter. In either event, the date o
set forth will not be more than 15 full business days after the date of such
notice. The date and time set forth in such notice is herein called the "Option
Closing Date." Upon     

                                      -3-
<PAGE>

     
exercise of such option, the Company will become obligated to convey to the
Representatives, and, subject to the terms and conditions set forth in Section
3(d) hereof, the Representatives will become obligated to purchase, the number
of Optional Shares specified in such notice.

     (c)  Payment for any Optional Shares purchased will be made to the Company
by wire transfer against delivery of the Optional Shares purchased to the
Representatives. The certificates representing the Optional Shares to be
delivered will be in such denominations and registered in such names as the
Representatives request not less than two full business days prior to the Option
Closing Date, and will be made available to the Representatives for inspection,
checking and packaging at the aforesaid office of the Company's transfer agent
or correspondent not less than one full business day prior to the Option Closing
Date.

     The obligation of the Representatives to purchase and pay for any of the
Optional Shares is subject to the accuracy and completeness (as of the date
hereof and as of the Option Closing Date) of and compliance in all material
respects with the representations and warranties of the Company herein, to the
accuracy and completeness of the statements of the Company or its officers made
in any certificate or other document to be delivered by the Company pursuant to
this Agreement, to the performance in all material respects by the Company of
its obligations hereunder, to the satisfaction by the Company of the conditions,
as of the date hereof and as of the Option Closing Date, set forth in Section
3(b) hereof, and to the delivery to the Representatives of opinions,
certificates and letters dated the Option Closing Date substantially similar in
scope to those specified in Sections 5 and 6(b), (c), (d) and (e) hereof, but
with each reference to "Offered Shares" and "Closing Date" to be, respectively,
to the Optional Shares and the Option Closing Date.

     4.   Representations and Warranties of the Company and Pulsar.  The Company
          -------------------------------------------------------- 
and Pulsar (defined hereinafter) each represents and warrants to, and agrees
with, the several Underwriters that:

          (a)  The Company is a corporation duly organized, validly existing and
in good standing under the laws of the State of Delaware, with full power and
authority, corporate and other, to own or lease, as the case may be, and operate
its properties and to conduct its business as described in the Registration
Statement and to execute, deliver and perform this Agreement and the
Representatives' Warrant Agreement and to consummate the transactions
contemplated hereby and thereby. The Company has no subsidiaries as of the date
hereof other than Litronic Industries, Inc., a corporation duly organized,
validly existing and in good standing under the laws of the State of California
("LIT"), and, as of the Closing Date, will have no subsidiaries other than LIT
and Pulsar Data Systems, Inc., a corporation duly organized, validly existing
and in good     

                                      -4-
<PAGE>

      
standing under the laws of the State of Delaware ("Pulsar" and, together with
LIT, the "Subsidiaries"). The Company has no equity interest in any entities
other than the Subsidiaries. Unless the context otherwise requires, all
references to the "Company" in this Agreement shall include the Subsidiaries.

          (b)  Each of the Company and the Subsidiaries is duly qualified to do
business as a foreign corporation and is in good standing in all jurisdictions
wherein such qualification is necessary and failure so to qualify could have a
material adverse effect on the financial condition, results of operations,
business or properties of the Company or any of the Subsidiaries. Each of the
Subsidiaries has full power and authority, corporate and other, and all Permits
(defined hereafter) necessary to own or lease, as the case may be, and operate
its properties and to conduct its business as described in the Registration
Statement. On the Closing Date, the Company will own all of the issued and
outstanding shares of capital stock of all of the Subsidiaries, free and clear
of any security interests, liens, encumbrances, claims and charges, and all of
such shares have been duly authorized and validly issued and are fully paid and
non-assessable. There are no options or warrants for the purchase of, or other
rights to purchase, or outstanding securities convertible into or exchangeable
for, any capital stock or other securities of any Subsidiary other than those
described in the Prospectus.

          (c)  This Agreement has been duly executed and delivered by the
Company and Pulsar and constitutes the valid and binding obligation of the
Company and Pulsar, enforceable against the Company and Pulsar in accordance
with its terms, and the Representatives' Warrant Agreement, when executed and
delivered by the Company on the Closing Date, will be the valid and binding
obligation of the Company, enforceable against the Company in accordance with
its terms. The execution, delivery and performance of this Agreement by the
Company and Pulsar and the Representatives' Warrant Agreement by the Company,
the consummation by the Company and Pulsar of the transactions herein
contemplated and by the Company of the transactions therein contemplated and the
compliance by the Company and Pulsar with the terms of this Agreement and by the
Company with the terms of the Representatives' Warrant Agreement have been duly
authorized by all necessary corporate action and do not and will not, with or
without the giving of notice or the lapse of time, or both, (i) result in any
violation of the Company's or of any of the Subsidiaries' Certificate of
Incorporation or Articles of Incorporation, as the case may be, or By-Laws (or
similar charter documents); (ii) result in a breach of or conflict with any of
the terms or provisions of,     

                                      -5-
<PAGE>

     
or constitute a default under, or result in the modification or termination of,
or result in the creation or imposition of any lien, security interest, charge
or encumbrance upon any of the properties or assets of the Company or any of the
Subsidiaries pursuant to any indenture, mortgage, note, contract, commitment or
other agreement or instrument to which the Company or any of the Subsidiaries is
a party or by which the Company or any of the Subsidiaries or any of their
respective properties or assets is or may be bound or affected; (iii) violate
any existing applicable law, rule, regulation, judgment, order or decree of any
governmental agency or court, domestic or foreign, having jurisdiction over the
Company or any of the Subsidiaries or any of their respective properties or
business; or (iv) have any effect on any permit, certification, registration,
approval, consent, order, license, franchise or other authorization
(collectively, the "Permits") necessary for the Company or any of the
Subsidiaries to own or lease and operate their respective properties or conduct
their respective businesses or the ability of the Company to make use thereof;
except in the case of clauses (ii), (iii) and (iv) where such breach, conflict,
default, violation, effect or other action or failure would not have a material
adverse effect on the business, financial condition, or results of operations of
the Company and its Subsidiaries taken as a whole.

          (d)  No Permits of any court or governmental agency or body, other
than under the Securities Act of 1933, as amended (the "Act"), the Regulations
(as hereinafter defined) and applicable state securities or Blue Sky laws, are
required (i) for the valid authorization, issuance, sale and delivery of the
Shares to the Underwriters, and (ii) the consummation by the Company of the
transactions contemplated by this Agreement and the Representatives' Warrant
Agreement or, if so required, all such Permits have been duly obtained and are
in full force and effect, except to the extent that the failure to obtain any
such Permit would not have a material adverse effect on the business, financial
condition or results of operations of the Company and its Subsidiaries taken as
a whole.

          (e)  The conditions for use of a registration statement on Form S-1
set forth in the General Instructions to Form S-1 have been satisfied with
respect to the Company and the transactions contemplated herein and in the
Registration Statement. The Company has prepared in all material respects in
conformity with the requirements of the Act and the rules and regulations (the
"Regulations") of the Securities and Exchange Commission (the "Commission") and
filed with the Commission a registration statement (File No. 333-72151) on Form
S-1 and has filed one or more amendments thereto, covering the registration of
the Shares under the Act, including the related preliminary prospectus or
preliminary prospectuses (each thereof being herein called a     

                                      -6-
<PAGE>

     
"Preliminary Prospectus") and a proposed final prospectus. Each Preliminary
Prospectus was endorsed with the legend required by Item 501(b)(10) of
Regulation S-K of the Regulations and, if applicable, Rule 430A of the
Regulations. Such registration statement including any documents incorporated by
reference therein and all financial schedules and exhibits thereto, as amended
at the time it becomes effective, and the final prospectus included therein are
herein, respectively, called the "Registration Statement" and the "Prospectus,"
except that, (i) if the prospectus filed by the Company pursuant to Rule 424(b)
of the Regulations differs from the Prospectus, the term "Prospectus" shall mean
the prospectus filed pursuant to Rule 424(b), and (ii) if the Registration
Statement is amended or such Prospectus is supplemented after the date the
Registration Statement is declared effective by the Commission (the "Effective
Date") and prior to the Option Closing Date, the terms "Registration Statement"
and "Prospectus" shall include the Registration Statement as amended or
supplemented.

          (f)  Neither the Commission nor, to the best of the Company's
knowledge, any state regulatory authority has issued any order preventing or
suspending the use of any Preliminary Prospectus or has instituted or, to the
best of the Company's knowledge, threatened to institute any proceedings with
respect to such an order.

          (g)  The Registration Statement when it becomes effective, the
Prospectus (and any amendment or supplement thereto) when it is filed with the
Commission pursuant to Rule 424(b), and both documents as of the Closing Date
and the Option Closing Date referred to below, will contain all statements which
are required to be stated therein in accordance with the Act and the Regulations
and will in all material respects conform to the requirements of the Act and the
Regulations, and neither the Registration Statement nor the Prospectus, nor any
amendment or supplement thereto, on such dates, will contain any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading, except that this
representation and warranty does not apply to statements or omissions made in
reliance upon and in conformity with information furnished in writing to the
Company in connection with the Registration Statement or Prospectus or any
amendment or supplement thereto by the Representatives, or by any Underwriter
through the Representatives, expressly for use therein.

          (h)  Based on the assumptions stated in the Registration Statement and
the Prospectus, the Company had at the date or dates indicated in the Prospectus
a duly authorized and outstanding capitalization as set forth in the
Registration     

                                      -7-
<PAGE>

     
Statement and the Prospectus, and on the Closing Date the Company will have the
adjusted stock capitalization set forth therein. Except as set forth in the
Registration Statement or the Prospectus, on the Effective Date and on the
Closing Date, there will be no options to purchase, warrants or other rights to
subscribe for, or any securities or obligations convertible into, or any
contracts or commitments to issue or sell shares of the Company's capital stock
or any such warrants, convertible securities or obligations. Except as set forth
in the Prospectus, no holder of any of the Company's securities has any rights,
"demand," "piggyback" or otherwise, to have such securities registered under the
Act.

          (i)  The descriptions in the Registration Statement and the Prospectus
of contracts and other documents are accurate and present fairly the information
required to be disclosed, and there are no contracts or other documents required
to be described in the Registration Statement or Prospectus or to be filed as
exhibits to the Registration Statement under the Act or the Regulations which
have not been so described or filed as required.

          (j)  KPMG LLP, the accountants who have certified the consolidated
financial statements of the Company and certain of the financial statements of
Pulsar (collectively, the "Financial Statements") filed and to be filed with the
Commission as part of the Registration Statement and the Prospectus, are
independent public accountants within the meaning of the Act and Regulations.
The Financial Statements and schedules and the notes thereto filed as part of
the Registration Statement and included in the Prospectus are complete, correct
and present fairly in all material respects the financial position of Pulsar and
the Company as of the dates thereof, and the results of operations and changes
in financial position of the Company and Pulsar for the periods indicated
therein, all in conformity with generally accepted accounting principles applied
on a consistent basis throughout the periods involved, except as otherwise
stated in the Registration Statement and the Prospectus. The selected financial
data set forth in the Registration Statement and the Prospectus present fairly
in all material respects the information shown therein and have been compiled on
a basis consistent with that of the audited and unaudited financial statements
included in the Registration Statement and the Prospectus.

          (k)  Each of the Company and the Subsidiaries has filed with the
appropriate federal, state and local governmental agencies, and all appropriate
foreign countries and political subdivisions thereof, all tax returns, including
franchise tax returns, which are required to be filed or has duly obtained
extensions of time for the filing thereof and has paid all taxes shown on such
returns and all assessments received by it to the     

                                      -8-
<PAGE>

     
extent that the same have become due; and the provisions for income taxes
payable, if any, shown on the Financial Statements filed with or as part of the
Registration Statement are sufficient for all accrued and unpaid foreign and
domestic taxes, whether or not disputed, and for all periods to and including
the dates of such Financial Statements. Except as disclosed in writing to the
Representatives, neither the Company nor any Subsidiary has executed or filed
with any taxing authority, foreign or domestic, any agreement extending the
period for assessment or collection of any income taxes and is not a party to
any pending action or proceeding by any foreign or domestic governmental agency
for assessment or collection of taxes; and no claims for assessment or
collection of taxes have been asserted against the Company or any Subsidiary.

          (l)  The outstanding Common Shares and outstanding options and
warrants to purchase Common Shares have been duly authorized and validly issued.
The outstanding Common Shares are fully paid and nonassessable. The outstanding
options and warrants to purchase Common Shares constitute the valid and binding
obligations of the Company, enforceable in accordance with their terms. None of
the outstanding Common Shares or options or warrants to purchase Common Shares
has been issued in violation of the preemptive rights of any shareholder of the
Company. None of the holders of the outstanding Common Shares is subject to
personal liability solely by reason of being such a holder. The offers and sales
of the outstanding Common Shares and outstanding options and warrants to
purchase Common Shares were at all relevant times either registered under the
Act and the applicable state securities or Blue Sky laws or exempt from such
registration requirements. The authorized Common Shares and outstanding options
and warrants to purchase Common Shares conform to the descriptions thereof
contained in the Registration Statement and Prospectus. Except as set forth in
the Registration Statement and the Prospectus, on the Effective Date and the
Closing Date, there will be no outstanding options or warrants for the purchase
of, or other outstanding rights to purchase, Common Shares or securities
convertible into Common Shares.

          (m)  No securities of the Company have been sold by the Company or by
or on behalf of, or for the benefit of, any person or persons controlling,
controlled by, or under common control with the Company within the three years
prior to the date hereof, except as disclosed in the Registration Statement.

          (n)  The issuance and sale of the Shares and the Warrant Shares have
been duly authorized and, when the Shares and the Warrant Shares have been
issued and duly delivered against payment therefor as contemplated by this
Agreement and the Representatives' Warrant Agreement, respectively, the Shares
and     

                                      -9-
<PAGE>

     
the Warrant Shares will be validly issued, fully paid and nonassessable, and the
holders thereof will not be subject to personal liability solely by reason of
being such holders. Neither the Shares nor the Warrant Shares will be subject to
preemptive rights of any shareholder of the Company.

          (o)  The issuance and sale of the Representatives' Warrants have
been duly authorized and, when issued, paid for and delivered as contemplated by
the Representatives' Warrant Agreement, the Representatives' Warrants will
constitute valid and binding obligations of the Company, enforceable as to the
Company in accordance with their terms. The Representatives' Warrants will not
be subject to preemptive rights of any shareholder of the Company. The Warrant
Shares have been duly reserved for issuance upon exercise of the
Representatives' Warrants in accordance with the provisions of the
Representatives' Warrant Agreement. The Representatives' Warrants conform to the
description thereof contained in the Registration Statement and Prospectus.

          (p)  Neither the Company nor any Subsidiary is in violation of (i) any
term or provision of its Certificate of Incorporation, Articles of Incorporation
(as the case may be) or By-Laws (or similar charter documents), each as amended;
(ii) in default in any material respect under any material term or provision or
any financial covenants of any indenture, mortgage, contract, commitment or
other agreement or instrument to which it is a party or by which it or any of
its property or business is or may be bound or affected; or (iii) in violation
in any material respect of any existing applicable law, rule, regulation,
judgment, order or decree of any governmental agency or court, domestic or
foreign, having jurisdiction over the Company, any Subsidiary or any of their
respective properties or business. The Company and each Subsidiary owns,
possesses or has obtained all governmental and other (including those obtainable
from third parties) Permits necessary to own or lease, as the case may be, and
to operate its properties, whether tangible or intangible, and to conduct the
business and operations of the Company as presently conducted, and all such
Permits are outstanding and in good standing, and there are no proceedings
pending or to the best of the Company's and Pulsar's knowledge, threatened (nor,
to the best of the Company's and Pulsar's knowledge, is there any basis
therefor) which seek to cancel, terminate or limit such Permits.

          (q)  Except as set forth in the Prospectus, there are no claims,
actions, suits, proceedings, arbitrations, investigations or inquiries before
any governmental agency, court or tribunal, domestic or foreign, or before any
private arbitration tribunal, pending, or, to the best of the Company's and
Pulsar's knowledge, threatened against the Company or any Subsidiary or
involving the Company's or any of the Subsidiaries' properties or     

                                      -10-

business which, if determined adversely to the Company or any of the
Subsidiaries would, individually or in the aggregate, result in any material
adverse change in the financial position, shareholders' equity, results of
operations, properties, business, management or affairs or business prospects of
the Company or any of the Subsidiaries or which question the validity of the
capital stock of the Company or this Agreement or of any action taken or to be
taken by the Company pursuant to, or in connection with, this Agreement; nor, to
the best of the Company's and Pulsar's knowledge, is there any basis for any
such claim, action, suit, proceeding, arbitration, investigation or inquiry.
There are no outstanding orders, judgments or decrees of any court, governmental
agency or other tribunal naming the Company or any of the Subsidiaries and
enjoining the Company or any of the Subsidiaries from taking, or requiring the
Company or any of the Subsidiaries to take, any action, or to which the Company
or any of the Subsidiaries or the Company's or any Subsidiaries' properties or
business is bound or subject.

          (r)  Neither the Company nor any of the Subsidiaries nor any of their
affiliates has incurred any liability for any finder's fees or similar payments
in connection with the transactions herein contemplated.

          (s)  Each of the Company and the Subsidiaries owns or possesses
adequate and enforceable rights to use all patents, patent applications,
trademarks, service marks, copyrights, rights, trade secrets, confidential
information, processes and formulations used or proposed to be used in the
conduct of its business as described in the Prospectus (collectively the
"Intangibles"); to the best of the Company's and Pulsar's knowledge, neither the
Company nor any of the Subsidiaries has infringed or is infringing upon the
rights of others with respect to the Intangibles; and neither the Company nor
any of the Subsidiaries has received any notice of conflict with the asserted
rights of others with respect to the Intangibles which could, singly or in the
aggregate, materially adversely affect its business as presently conducted or
the prospects, financial condition or results of operations of the Company or
any Subsidiary and neither the Company nor Pulsar knows of any basis therefor;
and, to the best of the Company's and Pulsar's knowledge, no others have
infringed upon the Intangibles of the Company or any Subsidiary.

          (t)  Since the respective dates as of which information is given in
the Registration Statement and the Prospectus and the Financial Statements,
neither the Company nor any Subsidiary has incurred any material liability or
obligation, direct or contingent, or entered into any material transaction,
whether or not incurred in the ordinary course of business, or sustained any
material loss or interference with its business from     

                                      -11-
<PAGE>

     
fire, storm, explosion, flood or other casualty, whether or not covered by
insurance, or from any labor dispute or court or governmental action, order or
decree; and since the respective dates as of which information is given in the
Registration Statement and the Prospectus, there have not been, and prior to the
Closing Date there will not be, any changes in the capital stock or any material
increases in the long-term debt of the Company or any Subsidiary or any material
adverse change in or affecting the general affairs, management, financial
condition, shareholders' equity, results of operations or prospects of the
Company or any Subsidiary, other than as set forth or contemplated in the
Prospectus.

          (u)  Neither the Company nor any Subsidiary owns any real property.
Each of the Company and the Subsidiaries has good title to all personal property
(tangible and intangible) owned by it, free and clear of all security interests,
charges, mortgages, liens, encumbrances and defects, except such as are
described in the Registration Statement and Prospectus or such as do not
materially affect the value or transferability of such property and do not
interfere with the use of such property made, or proposed to be made, by the
Company or any of the Subsidiaries. The leases, licenses or other contracts or
instruments under which the Company and the Subsidiaries lease, hold or are
entitled to use any property, real or personal, are valid, subsisting and
enforceable only with such exceptions as are not material and do not interfere
with the use of such property made, or proposed to be made, by the Company or
any Subsidiary, and all rentals, royalties or other payments, if any, accruing
thereunder which became due prior to the date of this Agreement have been duly
paid, and neither the Company nor any Subsidiary, nor, to the best of the
Company's and Pulsar's knowledge, any other party is in default thereunder and,
to the best of the Company's and Pulsar's knowledge, no event has occurred
which, with the passage of time or the giving of notice, or both, would
constitute a default thereunder. Neither the Company nor any Subsidiary has
received notice of any violation of any applicable law, ordinance, regulation,
order or requirement relating to its owned or leased properties. Each of the
Company and each of the Subsidiaries has adequately insured its properties
against loss or damage by fire or other casualty and maintains, in adequate
amounts, such other insurance as is usually maintained by companies engaged in
the same or similar businesses located in its geographic area.

          (v)  Each contract or other instrument (however characterized or
described) to which the Company or a Subsidiary is a party or by which their
respective properties or businesses are or may be bound or affected and to which
reference is made in the Prospectus has been duly and validly executed, is in
full force and effect in all material respects and is enforceable against 
the     

                                      -12-
<PAGE>

     
parties thereto in accordance with its terms, and none of such contracts or
instruments has been assigned by the Company or any Subsidiary, and neither the
Company nor any Subsidiary, nor, to the best of the Company's and Pulsar's
knowledge, any other party is in default thereunder and, to the best of the
Company's and Pulsar's knowledge, no event has occurred which, with the lapse of
time or the giving of notice, or both, would constitute a default thereunder.

     None of the material provisions of such contracts or instruments violates
any existing applicable law, rule, regulation, judgment, order or decree of any
governmental agency or court having jurisdiction over the Company or any
Subsidiary or any of their respective assets or businesses.

          (w)  The employment, consulting, confidentiality and non-competition
agreements between the Company and its officers, employees and consultants and
between each of the Subsidiaries and its respective officers, employees and
consultants, described in the Registration Statement, are binding and
enforceable obligations upon the respective parties thereto in accordance with
their respective terms, except as such enforceability may be limited by
applicable bankruptcy, insolvency, moratorium or other similar laws or
arrangements affecting creditors' rights generally and subject to principles of
equity.

          (x)  Except as set forth in the Prospectus, neither the Company nor
any Subsidiary has any employee benefit plans (including, without limitation,
profit sharing and welfare benefit plans) or deferred compensation arrangements
that are subject to the provisions of the Employee Retirement Income Security
Act of 1974, as amended.

          (y)  To the best of the Company's and Pulsar's knowledge, no labor
problem exists with any of the Company's employees or any Subsidiary's employees
or is imminent which could adversely affect the Company or any Subsidiary.

          (z)  Neither the Company nor any Subsidiary has, directly or
indirectly, at any time (i) made any contributions to any candidate for
political office, or failed to disclose fully any such contribution in violation
of law or (ii) made any payment to any state, federal or foreign governmental
officer or official, or other person charged with similar public or quasi-public
duties, other than, in each case, payments or contributions required or allowed
by applicable law. Each of the Company's and each of the Subsidiaries' internal
accounting controls and procedures are sufficient to cause the Company to comply
in all material respects with the Foreign Corrupt Practices Act of 1977, as
amended.

          (ac) The exchange by all of the stockholders of LIT of all of the
outstanding common stock of LIT for all of the currently outstanding Common

been completed on the terms described in the Prospectus.

          (ad) The Company has provided to Tenzer Greenblatt LLP, counsel to the
several Underwriters ("Underwriters' Counsel"), all material agreements,
certificates, correspondence and other items, documents and information
requested by such counsel's Corporate Review Memorandum dated September __,
1998.

     Any certificate signed by an officer of the Company or by an officer of a
Subsidiary and delivered to the Representatives or to Underwriters' Counsel
shall be deemed to be a representation and warranty by the Company to the
Underwriters as to the matters covered thereby.

     5.   Certain Covenants of the Company and Pulsar.  The Company and Pulsar
          -------------------------------------------                         
covenant with the several Underwriters as follows:

          (a)  The Company will not at any time, whether before the Effective
Date or thereafter during such period as the Prospectus is required by law to be
delivered in connection with the sales of the Shares by the Representatives or a
dealer, file or publish any amendment or supplement to the Registration
Statement or Prospectus of which the Representatives have not been 
previously     

                                      -14-
<PAGE>

     
advised and furnished a copy, or to which the Representatives shall in good
faith object in writing.

          (b)  The Company will use its best efforts to cause the Registration
Statement to become effective and will advise the Representatives promptly, and,
if requested by the Representatives, confirm such advice in writing, (i) when
the Registration Statement, or any post-effective amendment to the Registration
Statement or any supplemented Prospectus is filed with the Commission; (ii) of
the receipt of any comments from the Commission; (iii) of any request of the
Commission for amendment or supplementation of the Registration Statement or
Prospectus or for additional information; and (iv) of the issuance by the
Commission of any stop order suspending the effectiveness of the Registration
Statement or of any order preventing or suspending the use of any Preliminary
Prospectus, or of the suspension of the qualification of the Shares for offering
or sale in any jurisdiction, or of the initiation of any proceedings for any of
such purposes. The Company will use its best efforts to prevent the issuance of
any such stop order or of any order preventing or suspending such use and shall
use every reasonable effort to obtain as soon as possible the lifting thereof,
if any such order is issued.

          (c)  The Company will deliver to each Underwriter, without charge,
from time to time until the Effective Date, as many copies of each Preliminary
Prospectus as each Underwriter may reasonably request, and the Company hereby
consents to the use of such copies for purposes permitted by the Act. The
Company will deliver to each Underwriter, without charge, as soon as the
Registration Statement becomes effective, and thereafter from time to time as
requested, such number of copies of the Prospectus (as supplemented, if the
Company makes any supplements to the Prospectus) as each Underwriter may
reasonably request. The Company has furnished or will furnish to each of the
Representatives a signed copy of the Registration Statement as originally filed
and of all amendments thereto, whether filed before or after the Registration
Statement becomes effective, a copy of all exhibits filed therewith and a signed
copy of all consents and certificates of experts.

          (d)  The Company will comply with the Act, the Regulations, the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), and the rules
and regulations thereunder so as to permit the continuance of sales of and
dealings in the Offered Shares and in any Optional Shares which may be issued
and sold. If, at any time when a prospectus relating to the Shares is required
to be delivered under the Act, any event occurs as a result of which the
Registration Statement and Prospectus as then amended or supplemented would
include an untrue statement of a material fact or omit to state a material fact
necessary to make the statements     

                                      -15-
<PAGE>

     
therein, in light of the circumstances under which they were made, not
misleading, or if it shall be necessary to amend or supplement the Registration
Statement and Prospectus to comply with the Act or the regulations thereunder,
the Company will promptly file with the Commission, subject to Section 5(a)
hereof, an amendment or supplement which will correct such statement or omission
or which will effect such compliance.

          (e)  The Company will make generally available to its security
holders, in the manner specified in Rule 158(b) under the Act, and deliver to
the Representatives and Underwriters' Counsel as soon as practicable and in any
event not later than 45 days after the end of its fiscal quarter in which the
first anniversary date of the effective date of the Registration Statement
occurs, an earning statement meeting the requirements of Rule 158(a) under the
Act covering a period of at least 12 consecutive months beginning after the
effective date of the Registration Statement.

          (f)  For a period of three years from the Effective Date, the Company
will deliver to the Representatives, on a timely basis (i) a copy of each report
or document, including, without limitation, reports on Forms 8-K, 10-C, 10-K and
10-Q and exhibits thereto, filed or furnished to the Commission, any securities
exchange or the National Association of Securities Dealers, Inc. (the "NASD") on
the date each such report or document is so filed or furnished; (ii) as soon as
practicable, copies of any reports or communications (financial or other) of the
Company mailed to its security holders; (iii) as soon as practicable, a copy of
any Schedule 13D, 13G, 14D-1 or 13E-3 received or prepared by the Company from
time to time; (iv) to the extent available, quarterly statements setting forth
such information regarding the Company's results of operations and financial
position (including balance sheet, profit and loss statements and data regarding
backlog) as is regularly prepared by management of the Company; and (v) such
additional information concerning the business and financial condition of the
Company as the Representatives may from time to time reasonably request and
which can be prepared or obtained by the Company without unreasonable effort or
expense. The Company will furnish to its stockholders annual reports containing
audited financial statements and such other periodic reports as it may determine
to be appropriate or as may be required by law.

          (g)  Neither the Company nor any person that controls, is controlled
by or is under common control with the Company will take any action designed to
or which might be reasonably expected to cause or result in the stabilization or
manipulation of the price of the Common Shares.     

                                      -16-
<PAGE>

     
          (h)  If the transactions contemplated by this Agreement are
consummated, the Company will pay or cause to be paid the following: all costs
and expenses incident to the performance of the obligations of the Company under
this Agreement, including, but not limited to, the fees and expenses of
accountants and counsel for the Company; the preparation, printing, mailing and
filing of the Registration Statement (including financial statements and
exhibits), Preliminary Prospectuses and the Prospectus, and any amendments or
supplements thereto; the reproducing and mailing of the Selected Dealer
Agreement; the issuance and delivery of the Shares to the Representatives; all
taxes, if any, on the issuance of the Shares; the fees, expenses and other costs
of listing the Shares on Nasdaq and of qualifying the Shares for sale under the
"Blue Sky" or securities laws of those states in which the Shares are to be
offered or sold, including the fees and disbursements of Underwriters' Counsel
incurred in connection therewith, and the cost of reproducing and mailing the
"Blue Sky Survey"; the filing fees incident to securing any required review by
the NASD; the cost of furnishing to the several Underwriters copies of the
Registration Statement, Preliminary Prospectuses and the Prospectus as herein
provided; the costs of placing "tombstone advertisements" in any publications
which may be selected by the Representatives; and all other costs and expenses
incident to the performance of the Company's obligations hereunder which are not
otherwise specifically provided for in this Section 5(h).

     In addition, at the Closing Date and the Option Closing Date, the
Representatives will deduct from the payment for the Shares an amount equal to
the Representatives' accountable out-of-pocket costs, fees and expenses (up to
an aggregate maximum of $_______ [1.0% of the gross proceeds from the sale of
the Shares]) incurred in connection with the registration process, which amount
will include the fees and expenses of Underwriters' Counsel (other than those
payable by the Company in connection with "Blue Sky" qualifications referred to
in the preceding paragraph) incurred in connection with the registration process
and all of the costs associated with the marketing and selling of the Shares.

          (i)  If the transactions contemplated by this Agreement or related
hereto are not consummated because the Company and/or Pulsar decides not to
proceed with the offering and/or the Acquisition for any reason or if the
Representatives decide not to proceed with the offering because of a breach by
the Company and/or Pulsar of their representations, warranties or covenants in
this Agreement or as a result of adverse changes in the affairs of the Company
and/or Pulsar, the Company and Pulsar will reimburse the Representatives for all
of their accountable expenses reasonably incurred in connection with the
offering. In no event, however, will the Representatives, in the event the
offering is terminated,     

                                      -17-
<PAGE>

     
be entitled to receive more than an amount equal to their actual accountable 
out-of-pocket expenses.

          (j)  The Company intends to apply the net proceeds from the sale of
the Shares for the purposes set forth in the Prospectus.

          (k)  During the period of twenty-four (24) months following the date
hereof, (i) neither the Company nor any of its officers, directors or
securityholders will offer for sale, sell, transfer, pledge or otherwise dispose
of, directly or indirectly, any securities of the Company, in any manner
whatsoever, whether pursuant to Rule 144 of the Regulations or otherwise, (other
than by bona fide gift, will or the laws of descent or distribution to the
securityholder's spouse, children or grandchildren, or partnership, the general
partner of which is the securityholder (or a corporation, a majority of whose
outstanding stock is owned of record or beneficially by the securityholder or
any of the foregoing) or partners of the securityholder in connection with the
securityholder partnership's distribution of its Common Shares to its partners;
provided in each case that the transferee first executes and delivers to the
Underwriter an undertaking to be bound by the provisions of this Section 5(k))
provided that, after the first six (6) months of such period, this restriction
can be waived by BlueStone, in its sole discretion, and provided further that,
after the first twelve (12) months of such period, sales may be made, without
BlueStone's consent, as long as the number of shares (or share equivalents) sold
by all of such holders, in the aggregate, does not exceed, during any 90-day
period, the greater of (I) 1% of the then outstanding shares of Common Stock and
(II) the average weekly trading volume of the Common Stock during the four
calendar weeks preceding the holder's sale, and (ii) no holder of registration
rights relating to securities of the Company will execute any such registration
rights without the prior written consent of BlueStone. The Company will deliver
to the Representatives the undertakings as of the date hereof of its officers,
directors and securityholders to this effect.

          (l)  The Company will not file any registration statement relating to
the offer or sale of any of the Company's securities, including any registration
statement on Form S-8, during the twenty-four (24) months following the date
hereof (the "Restriction Period") without BlueStone's prior written consent;
except that after the twelve month (12) anniversary of the date hereof, the
Company may file a registration statement on Form S-8, provided that no more
than 100,000 shares of Common Stock may be sold pursuant to such registration
statement during the Restriction Period by persons who are not officers or
directors of the Company or family members of an officer or director of the
Company.     

                                      -18-
<PAGE>

     
          (m)  The Company maintains and will continue to maintain a system of
internal accounting controls sufficient to provide reasonable assurances that:
(i) transactions are executed in accordance with management's general or
specific authorization; (ii) transactions are recorded as necessary in order to
permit preparation of financial statements in accordance with generally accepted
accounting principles and to maintain accountability for assets; (iii) access to
assets is permitted only in accordance with management's general or specific
authorization; and (iv) the recorded accountability for assets is compared with
existing assets at reasonable intervals and appropriate action is taken with
respect to any differences.

          (n)  The Company will use its best efforts to maintain the listing of
the Shares on Nasdaq or another exchange that is mutually agreed upon by the
Company and the Representatives for so long as the Shares are qualified for such
listing.

          (o)  The Company will, concurrently with the Effective Date, register
the class of equity securities of which the Shares are a part under Section
12(g) of the Exchange Act and the Company will maintain the registration for a
minimum of five (5) years after the Effective Date.

          (p)  Subject to the sale of the Offered Shares, BlueStone and its
successors will have the right to designate up to two (2) nominees for election,
at its or their option, either as members of or non-voting advisors to the Board
of Directors of the Company, and the Company will use its best efforts to cause
such nominees to be elected and continued in office as a director of the Company
or as such advisor until the expiration of three (3) years from the Effective
Date. Following the election of such nominee(s) as a director(s) or advisor(s),
such persons shall receive no more or less compensation than is paid to other
non-officer directors of the Company for attendance at meetings of the Board of
Directors of the Company and shall be entitled to receive reimbursement for all
reasonable costs incurred in attending such meetings, including, but not limited
to, food, lodging and transportation. The Company agrees to indemnify and hold
each of such director(s) and/or advisor(s)harmless, to the maximum extent
permitted by law, against any and all claims, actions, awards and judgments
arising out of his service as a director or advisor and, in the event the
Company maintains a liability insurance policy affording coverage for the acts
of its officers and directors, to include such director(s) or advisor(s) as an
insured under such policy. The rights and benefits of such indemnification and
the benefits of such insurance shall, to the extent possible, extend to
BlueStone insofar as it may be or may be alleged to be responsible for such
director(s) or advisor(s).     

                                      -19-
<PAGE>

     
     If BlueStone does not exercise its option to designate members of or
advisors to the Company's Board of Directors, it shall nonetheless have the
right to send a representative (who need not be the same individual from meeting
to meeting) to observe each meeting of the Board of Directors.  The Company
agrees to give BlueStone notice of each such meeting and to provide BlueStone
with an agenda and minutes of the meeting no later than it gives such notice and
provides such items to the directors.

          (q)  The Company shall retain a transfer agent for the Common Shares,
reasonably acceptable to BlueStone, for a period of three (3) years following
the Effective Date. In addition, for a period of three (3) years following the
Effective Date, the Company, at its own expense, shall cause its transfer agent
to provide BlueStone, if so requested in writing, with copies of the Company's
daily transfer sheets and when requested by BlueStone, a current list of the
Company's security holders, including a list of the beneficial owners of
securities held by a depository trust company and other nominees.

          (r)  The Company hereby agrees, at its sole cost and expense, to
supply and deliver to Underwriters' Counsel, within a reasonable period from the
date hereof, five bound volumes, including the Registration Statement, as
amended or supplemented, all exhibits to the Registration Statement, the
Prospectus and all other underwriting documents.

          (s)  The Company shall, within ten days of the date hereof, have
applied for listing in Standard & Poor's Corporation Records Service (including
annual report information) or Moody's Industrial Manual (Moody's OTC Industrial
Manual not being sufficient for these purposes) and shall use its best efforts
to have the Company listed in such manual and shall maintain such listing for a
period of three (3) years following the Effective Date.

          (t)  For a period of two (2) years from the Effective Date, the
Company shall provide BlueStone, on a not less than annual basis, with internal
forecasts setting forth projected results of operations for each annual period
in the two (2) fiscal years following the respective dates of such forecasts;
provided, however, that BlueStone shall keep confidential and shall not disclose
to any third party any material non-public information. Such forecasts shall be
provided to BlueStone more frequently than annually if prepared more frequently
by management, and revised forecasts shall be prepared and provided to BlueStone
when required to reflect more current information, revised assumptions or actual
results that differ materially from those set forth in the forecasts.

          (u)  For a period of three (3) years following the Effective Date, the
Company shall continue to retain KPMG Peat Marwick LLP (or such other nationally
recognized accounting firm as is acceptable to BlueStone) as the Company's
independent public accountants.

          (v)  For a period of three (3) years following the Effective Date, the
Company, at its expense, shall cause its independent certified public
accountants, as described in Section 5(u) above, to review (but not audit) the
Company's financial statements for each of the first three fiscal quarters prior
to the announcement of quarterly financial information, the filing of the
Company's 10-Q quarterly report and the mailing of quarterly financial
information to shareholders.

          (w)  For a period of twenty-five (25) days following the Effective
Date, the Company will not issue press releases or engage in any other publicity
without BlueStone's prior written consent, other than normal and customary
releases issued in the ordinary course of the Company's business or those
releases required by law.

          (x)  For a period of three (3) years following the Effective Date, the
Company will cause its Board of Directors to meet, either in person or
telephonically, a minimum of four (4) times per year and will hold a
shareholder's meeting at least once per annum.

          (y)  For a period of 18 months following the Effective Date, the
Company will not offer or sell any of its securities (i) pursuant to Regulation
S of the Act, or (ii) at a discount from the then current market price, without
the prior written consent of BlueStone.

          (z)  On or prior to the Closing Date, the Company will complete the
Acquisition on the terms described in the Prospectus.

Offered Shares which they have agreed to purchase from the Company is subject

substantially in the form of Exhibit 6(b) hereto.

     In rendering its opinion pursuant to this Section 6(b), Company counsel may

as to matters of fact, provided that Company shall state that they have no
reason to believe, and no not believe, that they are justified in relying upon

     The opinion letters delivered pursuant to this Section 6(b) shall state
that any opinion given therein qualified by the phrase "to the best of our
knowledge" is being given by Company Counsel after due investigation of the
matters therein discussed.

          (c)  At the Closing Date, there will have been delivered to the
Representatives a signed opinion of Underwriters' Counsel, dated as of the
Closing Date, to the effect that the opinions delivered pursuant to Section 6(b)
hereof appear on their face to be appropriately responsive to the requirements

Prospectus and any amendments or supplements thereto will contain all material
statements which are required to be stated therein in accordance with the Act
and the Regulations and will conform in all material respects to the
requirements of the Act and the Regulations, and neither the Registration
Statement nor the Prospectus nor any amendment or supplement thereto will

                                      -22-
<PAGE>

     
any material fact required to be stated therein or necessary to make the

not misleading; (ii) since the respective dates as of which information is given
in the Registration Statement and the Prospectus, there will not have been any
material adverse change in the financial condition, results of operations or
general affairs of the Company from that set forth or contemplated in the
Registration Statement and the Prospectus, except changes which the Registration
Statement and the Prospectus indicate might occur after the Effective Date;
(iii) since the respective dates as of which information is given in the
Registration Statement and the Prospectus, there shall have been no material

Registration Statement and the Prospectus, other than as set forth therein; and
(iv) no action, suit or proceeding at law or in equity will be pending or, to
the best of the Company's knowledge, threatened against the Company which is
required to be set forth in the Registration Statement and the Prospectus, other
than as set forth therein, and no proceedings will be pending or, to the best of
the Company's knowledge, threatened against the Company before or by any
federal, state or other commission, board or administrative agency wherein an
unfavorable decision, ruling or finding would materially adversely affect the
business, property, financial condition or results of operations of the Company,
other than as set forth in the Registration Statement and the Prospectus. At the
Closing Date, there will be delivered to the Representatives a certificate
signed by the Chairman of the Board or the President or a Vice President of the

Company set forth in Section 4 hereof were accurate and complete in all material
respects when made on the date hereof and are accurate and complete in all
material respects on the Closing Date as if then made; that the Company has
performed all covenants and complied with all conditions required by this
Agreement to be performed or complied with by the Company prior to or as of the
Closing Date; and that, as of the Closing Date, no stop order suspending the
effectiveness of the Registration Statement has been issued and no proceedings
for that purpose have been initiated or, to the best of his knowledge, are
contemplated or threatened. In addition, the Representatives will have received
such other and further certificates of officers of the Company as the
Representatives or Underwriters' Counsel may reasonably request.

          (e)  At the time that this Agreement is executed and at the Closing
Date, the Representatives will have received a signed letter from KPMG LLP,
dated the date such letter is to be received by the Representatives and
addressed to it, confirming that it is a firm of independent public accountants
within the     

                                      -23-
<PAGE>

     
meaning of the Act and Regulations and stating that: (i) insofar as reported on
by it, in its opinion, the Financial Statements included in the Prospectus
comply as to form in all material respects with the applicable accounting
requirements of the Act and the applicable Regulations; (ii) on the basis of
procedures and inquiries (not constituting an examination in accordance with
generally accepted auditing standards) consisting of a reading of the unaudited
interim financial statements of the Company, if any, appearing in the
Registration Statement and the Prospectus and the latest available unaudited
interim financial statements of the Company and Pulsar, if more recent than that
appearing in the Registration Statement and Prospectus, inquiries of officers of
the Company and officers of Pulsar responsible for financial and accounting
matters as to the transactions and events subsequent to the date of the latest
audited financial statements of the Company and Pulsar, and a reading of the
minutes of meetings of the shareholders, the Board of Directors and any
committees of the Board of Directors of each of the Company and of Pulsar, as
set forth in the minute books of the Company and of Pulsar, nothing has come to
its attention which, in its judgment, would indicate that (A) during the period
from the date of the latest financial statements of the Company and Pulsar
appearing in the Registration Statement and Prospectus to a specified date not
more than three business days prior to the date of such letter, there have been
any decreases in net current assets or net assets as compared with amounts shown
in such financial statements or decreases in net sales or decreases in total or
per share net income compared with the corresponding period in the preceding
year or any change in the capitalization or long-term debt of the Company or
Pulsar, except in all cases as set forth in or contemplated by the Registration
Statement and the Prospectus, and (B) the unaudited interim financial statements
of the Company and Pulsar, if any, appearing in the Registration Statement and
the Prospectus, do not comply as to form in all material respects with the
applicable accounting requirements of the Act and the Regulations or are not
fairly presented in conformity with generally accepted accounting principles and
practices on a basis substantially consistent with the audited financial
statements included in the Registration Statement or the Prospectus; and (iii)
it has compared specific dollar amounts, numbers of shares, numerical data,
percentages of revenues and earnings, and other financial information pertaining
to the Company and Pulsar set forth in the Prospectus (with respect to all
dollar amounts, numbers of shares, percentages and other financial information
contained in the Prospectus, to the extent that such amounts, numbers,
percentages and information may be derived from the general accounting records
of the Company or Pulsar, and excluding any questions requiring an
interpretation by legal counsel) with the results obtained from the application
of specified readings, inquiries and other appropriate procedures (which
procedures do not constitute an examination in accordance      

                                      -24-
<PAGE>
     
with generally accepted auditing standards) set forth in the letter, and found
them to be in agreement.

          (f)  There shall have been duly tendered to the Representatives
certificates representing the Offered Shares to be sold on the Closing Date.

          (g)  The NASD shall have indicated that it has no objection to the
underwriting arrangements pertaining to the sale of the Offered Shares by the
Underwriters or the sale of the Shares by the Representatives.

          (h)  No action shall have been taken by the Commission or the NASD the
effect of which would make it improper, at any time prior to the Closing Date or
the Option Closing Date, as the case may be, for any member firm of the NASD to
execute transactions (as principal or as agent) in the Shares, and no
proceedings for the purpose of taking such action shall have been instituted or
shall be pending, or, to the best of the Representatives' or the Company's
knowledge, shall be contemplated by the Commission or the NASD. The Company
represents at the date hereof, and shall represent as of the Closing Date or
Option Closing Date, as the case may be, that it has no knowledge that any such
action is in fact contemplated by the Commission or the NASD.

          (i)  The Common Shares have been approved for listing on Nasdaq.

          (j)  All proceedings taken at or prior to the Closing Date or the
Option Closing Date, as the case may be, in connection with the authorization,
issuance and sale of the Shares shall be reasonably satisfactory in form and
substance to the Representatives and to Underwriters' Counsel, and such counsel
shall have been furnished with all such documents, certificates and opinions as
they may request for the purpose of enabling them to pass upon the matters
referred to in Section 6(c) hereof and in order to evidence the accuracy and
completeness of any of the representations, warranties or statements of the
Company, the performance of any covenants of the Company, or the compliance by
the Company with any of the conditions herein contained.

          (k)  As of the date hereof, the Company will have delivered to the
Representatives the written undertakings of its officers, directors and security
holders and/or registration rights holders, as the case may be, to the effect of
the matters set forth in Section 5(l).

          (l)  Each of the Company's current officers, directors and
securityholders shall have agreed to vote all of the Common Shares owned by such
person or entity so as to elect and     

                                      -25-

continue in office such nominee(s) of BlueStone as more fully set forth in
section 5(p) above.

     If any of the conditions specified in this Section 6 have not been
fulfilled, this Agreement may be terminated by the Representatives on notice to
the Company.

     7.   Indemnification.
          ----------------

          (a)  Each of the Company and Pulsar agrees, jointly and severally, to
indemnify and hold harmless each Underwriter, including specifically each person
that may be substituted for an Underwriter as provided in Section 10 hereof,
each officer, director, partner, employee and agent of any Underwriter, and each
person, if any, who controls any of the Underwriters within the meaning of
Section 15 of the Act or Section 20(a) of the Exchange Act, from and against any
and all losses, claims, damages, expenses or liabilities, joint or several (and
actions in respect thereof), to which they or any of them may become subject
under the Act or under any other statute or at common law or otherwise, and,
except as hereinafter provided, will reimburse each of the Underwriters and each
such person, if any, for any legal or other expenses reasonably incurred by them
or any of them in connection with investigating or defending any actions,
whether or not resulting in any liability, insofar as such losses, claims,
damages, expenses, liabilities or actions arise out of or are based upon any
untrue statement or alleged untrue statement of a material fact contained (i) in
the Registration Statement, in any Preliminary Prospectus or in the Prospectus
(or the Registration Statement or Prospectus as from time to time amended or
supplemented) or (ii) in any application or other document executed by the
Company, or based upon written information furnished by or on behalf of the
Company, filed in any jurisdiction in order to qualify the Shares under the
securities laws thereof (hereinafter "application"), or arise out of or are
based upon the omission or alleged omission to state therein a material fact
required to be stated therein or necessary in order to make the statements
therein not misleading, in light of the circumstances under which they were
made, unless such untrue statement or omission was made in such Registration
Statement, Preliminary Prospectus, Prospectus or application in reliance upon
and in conformity with information furnished in writing to the Company in
connection therewith by the Underwriter or any such person through the
Underwriter expressly for use therein; provided, however, that the indemnity
agreement contained in this Section 7(a) with respect to any Preliminary
Prospectus will not inure to the benefit of the Underwriter (or to the benefit
of any other person that may be indemnified pursuant to this Section 7(a)) if
(A) the person asserting any such losses, claims, damages, expenses or
liabilities purchased the Shares which are the subject thereof from such
Underwriter or other indemnified person; (B) such     

                                      -26-
<PAGE>

     
Underwriter or other indemnified person failed to send or give a copy of the
Prospectus to such person at or prior to the written confirmation of the sale of
such Shares to such person; and (C) the Prospectus did not contain any untrue
statement or alleged untrue statement or omission or alleged omission giving
rise to such cause, claim, damage, expense or liability.

          (b)  Each Underwriter (including specifically each person that may be
substituted for an Underwriter as provided in Section 11 hereof) agrees to
indemnify and hold harmless the Company, each of its directors, each of its
officers who have signed the Registration Statement and each person, if any, who
controls the Company within the meaning of Section 15 of the Act or Section
20(a) of the Exchange Act, from and against any and all losses, claims, damages,
expenses or liabilities, joint or several (and actions in respect thereof), to
which they or any of them may become subject under the Act or under any other
statute or at common law or otherwise, and, except as hereinafter provided, will
reimburse the Company and each such director, officer or controlling person for
any legal or other expenses reasonably incurred by them or any of them in
connection with investigating or defending any actions, whether or not resulting
in any liability, insofar as such losses, claims, damages, expenses, liabilities
or actions arise out of or are based upon any untrue statement or alleged untrue
statement of a material fact contained (i) in the Registration Statement, in any
Preliminary Prospectus or in the Prospectus (or the Registration Statement or
Prospectus as from time to time amended or supplemented) or (ii) in any
application (including any application for registration of the Shares under
state securities or Blue Sky laws), or arise out of or are based upon the
omission or alleged omission to state therein a material fact required to be
stated therein or necessary in order to make the statements therein not
misleading, in light of the circumstances under which they were made, but only
insofar as any such statement or omission was made in reliance upon and in
conformity with information furnished in writing to the Company in connection
therewith by such Underwriter, or by the Representatives on behalf of such
Underwriter, expressly for use therein.

          (c)  Promptly after receipt of notice of the commencement of any
action in respect of which indemnity may be sought against any indemnifying
party under this Section 7, the indemnified party will notify the indemnifying
party in writing of the commencement thereof, and the indemnifying party will,
subject to the provisions hereinafter stated, assume the defense of such action
(including the employment of counsel satisfactory to the indemnified party and
the payment of expenses) insofar as such action relates to an alleged liability
in respect of which indemnity may be sought against the indemnifying party.
After notice from the indemnifying party of its election to assume the     

                                      -27-
<PAGE>

     
defense of such claim or action, the indemnifying party shall no longer be
liable to the indemnified party under this Section 7 for any legal or other
expenses subsequently incurred by the indemnified party in connection with the
defense thereof other than reasonable costs of investigation; provided, however,
that if, in the reasonable judgment of the indemnified party or parties, it is
advisable for the indemnified party or parties to be represented by separate
counsel, the indemnified party or parties shall have the right to employ a
single counsel to represent the indemnified parties who may be subject to
liability arising out of any claim in respect of which indemnity may be sought
by the indemnified parties thereof against the indemnifying party, in which
event the fees and expenses of such separate counsel shall be borne by the
indemnifying party. Any party against whom indemnification may be sought under
this Section 7 shall not be liable to indemnify any person that might otherwise
be indemnified pursuant hereto for any settlement of any action effected without
such indemnifying party's consent.

          8.   Contribution. To provide for just and equitable contribution, if
               ------------        
(i) an indemnified party makes a claim for indemnification pursuant to Section 8
hereof (subject to the limitations thereof) and it is finally determined, by a
judgment, order or decree not subject to further appeal, that such claim for
indemnification may not be enforced, even though this Agreement expressly
provides for indemnification in such case; or (ii) any indemnified or
indemnifying party seeks contribution under the Act, the Exchange Act, or
otherwise, then the Company and Pulsar (including, for this purpose, any
contribution made by or on behalf of any director of the Company, any officer of
the Company who signed the Registration Statement and any controlling person of
the Company) as one entity and the Underwriters (including, for this purpose,
any contribution by or on behalf of each person, if any, who controls any
Underwriter within the meaning of Section 15 of the Act or Section 20(a) of the
Exchange Act and each officer, director, partner, employee and agent of any of
the Underwriters) as a second entity, shall contribute to the losses,
liabilities, claims, damages and expenses whatsoever to which any of them may be
subject, so that the Underwriters are responsible for the proportion thereof
equal to the percentage which the underwriting discount per Share set forth on
the cover page of the Prospectus represents of the initial public offering price
per Share set forth on the cover page of the Prospectus and the Company is
responsible for the remaining portion; provided, however, that if applicable law
does not permit such allocation, then, if applicable law permits, other relevant
equitable considerations such as the relative fault of the Company and Pulsar on
the one hand, and the Underwriters, on the other hand, in connection with the
facts which resulted in such losses, liabilities, claims, damages and expenses
shall also be considered. The relative fault, in the case of an     

                                      -28-
<PAGE>

     
untrue statement, alleged untrue statement, omission or alleged omission, shall
be determined by, among other things, whether such statement, alleged statement,
omission or alleged omission relates to information supplied by the Company or
by the Underwriters, and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement, alleged
statement, omission or alleged omission. The Company and Pulsar, on one hand,
and the Underwriters, on the other hand, agree that it would be unjust and
inequitable if the respective obligations of the Company, Pulsar and the
Underwriters for contribution were determined by pro rata or per capita
allocation of the aggregate losses, liabilities, claims, damages and expenses or
by any other method of allocation that does not reflect the equitable
considerations referred to in this Section 8. No person guilty of a fraudulent
misrepresentation (within the meaning of Section 11(f) of the Act) will be
entitled to contribution from any person who is not guilty of such fraudulent
misrepresentation. For purposes of this Section 8, each person, if any, who
controls any of the Underwriters within the meaning of Section 15 of the Act or
Section 20(a) of the Exchange Act and each officer, director, partner, employee
and agent of any of the Underwriters will have the same rights to contribution
as the Underwriters, and each person, if any, who controls the Company within
the meaning of Section 15 of the Act or Section 20(a) of the Exchange Act, each
officer of the Company who has signed the Registration Statement and each
director of the Company will have the same rights to contribution as the
Company, subject in each case to the provisions of this Section 8. Anything in
this Section 8 to the contrary notwithstanding, no party will be liable for
contribution with respect to the settlement of any claim or action effected
without its written consent. This Section 8 is intended to supersede, to the
extent permitted by law, any right to contribution under the Act or the Exchange
Act or otherwise available.

          9.   Survival of Indemnities, Contribution, Warranties and
               -----------------------------------------------------
Representations. The respective indemnity and contribution agreements of the
- ---------------
Company, Pulsar and the Underwriters contained in Sections 7 and 8 hereof, and
the representations and warranties of the Company and Pulsar contained in this
Agreement shall remain operative and in full force and effect, regardless of any
termination or cancellation of this Agreement or any investigation made by or on
behalf of the Underwriters, the Company or any of its directors and officers or
Pulsar or any controlling person referred to in said Sections, and shall survive
the delivery of, and payment for, the Shares.

          10.  Substitution of Underwriters.
               -----------------------------

               (a)  If one or more Underwriters should default in its or their
obligation to purchase and pay for any Offered Shares     

                                      -29-
<PAGE>

     
hereunder and if the aggregate number of such Offered Shares which all
Underwriters so defaulting have agreed to purchase does not exceed 10% of the
total number of the Offered Shares, the non-defaulting Underwriters will be
obligated severally to purchase and pay for (in addition to the number of
Offered Shares set forth opposite their names in Schedule A attached hereto) the
full number of Offered Shares agreed to be purchased by all defaulting
Underwriters, and not so purchased, in proportion to their respective
commitments hereunder. In such event the Representatives, for the accounts of
the several nondefaulting Underwriters, may take up and pay for all or any part
of such additional Offered Shares to be purchased by each such Underwriter under
this Section 10(a), and may postpone the Closing Date to a time not exceeding
three full business days after the Closing Date determined as provided in
Section 2 hereof.

               (b)  If one or more Underwriters should default in its or their
obligation to purchase and pay for any Offered Shares hereunder and if the
aggregate number of such Offered Shares which all Underwriters so defaulting
have agreed to purchase exceeds 10% of the total number of Offered Shares, or if
one or more Underwriters for any reason permitted hereunder should cancel its or
their obligation to purchase and pay for Offered Shares hereunder, the non-
cancelling and non-defaulting Underwriters (hereinafter called the "remaining
Underwriters") will have the right to purchase such Offered Shares in such
proportion as may be agreed among them at the Closing Date determined as
provided in Section 2 hereof. If the remaining Underwriters do not purchase and
pay for such Offered Shares at such Closing Date, the Closing Date will be
postponed for 24 hours and the remaining Underwriters will have the right to
purchase such Offered Shares, or to substitute another person or persons to
purchase the same, or both, at such postponed Closing Date. If purchasers have
not been found for such Offered Shares by such postponed Closing Date, the
Closing Date will be postponed for a further 24 hours, and the Company will have
the right to substitute another person or persons, reasonably satisfactory to
the Representatives to purchase such Offered Shares at such second postponed
Closing Date. If it shall be arranged for the remaining Underwriters or
substituted underwriters to take up the Firm Shares of the defaulting
Underwriter or Underwriters as provided in this Section, (A) the Company shall
have the right to postpone the time of delivery for a period of not more than
three (3) full Business Days, in order to effect whatever changes may thereby be
made necessary in the Registration Statement or the Prospectus or in any other
documents or arrangements, and the Company agrees promptly to file any
amendments to the Registration Statement or supplements to the Prospectus which
may thereby be made necessary. If the Company has not found such purchasers for
such Offered Shares by such second postponed Closing Date, then this Agreement
will automatically terminate, and neither the     

                                      -30-
<PAGE>

     
Company nor the remaining Underwriters will be under any obligation under this
Agreement (except that the Company and the Underwriters will remain liable to
the extent provided in Sections 7 and 8 hereof and the Company will also remain
liable to the extent provided in Section 5(j) hereof). As used in this
Agreement, the term "Underwriter" includes any person substituted for an
Underwriter under this Section 10(b). Nothing in Section 11 hereof will relieve
a defaulting Underwriter from the liability for its default and nothing in this
Section 10(b) will obligate any Underwriter to purchase or find purchasers for
any Offered Shares in excess of those agreed to be purchased by such Underwriter
under the terms of Section 2 hereof.

          11.  Termination of Agreement.
               -------------------------

               (a)  The Company, by written or telegraphic notice to the
Representatives, or the Representatives, by written or telegraphic notice to the
Company, may terminate this Agreement prior to the earlier of (i) 11:00 A.M.,
New York City time, on the first full business day after the Effective Date; or
(ii) the time when the Underwriters, after the Registration Statement becomes
effective, release the Offered Shares for public offering. The time when the
Underwriters "release the Offered Shares for public offering" for the purposes
of this Section 11 means the time when the Underwriters release for publication
the first newspaper advertisement, which is subsequently published, relating to
the Offered Shares, or the time when the Underwriters release for delivery to
members of a selling group copies of the Prospectus and an offering letter or an
offering telegram relating to the Offered Shares, whichever will first occur.

               (b)  This Agreement, including without limitation, the obligation
to purchase the Shares and the obligation to purchase the Optional Shares after
exercise of the option referred to in Section 3 hereof, is subject to
termination in the absolute discretion of the Underwriters, by notice given to
the Company prior to delivery of and payment for all the Offered Shares or the
Optional Shares, as the case may be, if, prior to such time, any of the
following shall have occurred: (i) the Company withdraws the Registration
Statement from the Commission or the Company does not or cannot expeditiously
proceed with the public offering; (ii) the representations and warranties in
Section 4 hereof are not materially correct or cannot be complied with; (iii)
trading in securities generally on the New York Stock Exchange or the American
Stock Exchange will have been suspended, other than intra-day programmed trading
curbs imposed by Nasdaq; (iv) limited or minimum prices will have been
established on either such Exchange; (v) a banking moratorium will have been
declared either by federal or New York State authorities; (vi) any other
restrictions on transactions in securities materially affecting the free market
for securities     

                                      -31-
<PAGE>

     
or the payment for such securities, including the Offered Shares or the Optional
Shares, will be established by either of such Exchanges, by the Commission, by
any other federal or state agency, by action of the Congress or by Executive
Order; (vii) trading in any securities of the Company shall have been suspended
or halted by any national securities exchange, the NASD or the Commission;
(viii) there has been a materially adverse change in the condition (financial or
otherwise), prospects or obligations of the Company; (ix) the Company will have
sustained a material loss, whether or not insured, by reason of fire, flood,
accident or other calamity; (x) any action has been taken by the government of
the United States or any department or agency thereof which, in the judgment of
the Representatives, has had a material adverse effect upon the market or
potential market for securities in general; or (xi) the market for securities in
general or political, financial or economic conditions will have so materially
adversely changed that, in the judgment of the Representatives, it will be
impracticable to offer for sale, or to enforce contracts made by the
Underwriters for the resale of, the Offered Shares or the Optional Shares, as
the case may be.

          (c)  If this Agreement is terminated pursuant to Section 6 hereof or
this Section 11 or if the purchases provided for herein are not consummated
because any condition of the Underwriters' obligations hereunder is not
satisfied or because of any refusal, inability or failure on the part of the
Company to comply with any of the terms or to fulfill any of the conditions of
this Agreement, or if for any reason the Company shall be unable to or does not
perform all of its obligations under this Agreement, the Company will not be
liable to any of the Underwriters for damages on account of loss of anticipated
profits arising out of the transactions covered by this Agreement, but the

                                 EXHIBIT 6(b)


                    (i)  The Company is a corporation duly organized, validly
existing and in good standing under the laws of the State of Delaware, with full
power and authority, corporate and other, and with all Permits necessary to own
or lease, as the case may be, and operate its properties, whether tangible or
intangible, and to conduct its business as described in the Registration
Statement. Other than LIT, the Company has no subsidiaries as of the date hereof
and, as of the Closing Date, will have no subsidiaries other than LIT and
Pulsar. The Company has no equity interest in any entities other than the
Subsidiaries. Each of the Subsidiaries is a corporation duly organized and
validly existing under the laws of its state of incorporation. Unless the
context otherwise requires, all references to the "Company" in this opinion
shall include the Subsidiaries. Each of the Company and of the Subsidiaries is
duly qualified to do business as a foreign corporation and is in good standing
in all jurisdictions wherein such qualification is necessary and failure so to
qualify could have a material adverse effect on the financial condition, results
of operations, business or properties of the Company. Each of the Subsidiaries
has full power and authority, corporate and other, and all Permits necessary to
own or lease, as the case may be, and operate its properties, whether tangible
or intangible, and to conduct its business as described in the Registration
Statement.

          On the Closing Date, the Company will own all of the issued and
outstanding shares of capital stock of each of the Subsidiaries, free and clear
of any security interests, liens, encumbrances, claims and charges, and all of
such shares have been duly authorized and validly issued and are fully paid and
non-assessable. There are no options or warrants for the purchase of, or other
rights to purchase, or outstanding securities convertible into or exchangeable
for, any capital stock or other securities of any Subsidiary other than those
described in the Prospectus.

                    (ii) The Company and Pulsar each has full power and
authority, corporate and other, to execute, deliver and perform this Agreement
and to consummate the transactions contemplated hereby and the Company has full
power and authority, corporate and other, to execute, deliver and perform the
Representatives' Warrant Agreement and to consummate the transactions
contemplated thereby. The execution, delivery and performance of this Agreement
by the Company and Pulsar and the Representatives' Warrant Agreement by the
Company, the consummation by the Company and Pulsar of the transactions herein
and by the Company of the transactions therein contemplated and the compliance
by the Company and Pulsar with the terms of this Agreement and by the Company
with the terms of the Representatives' Warrant Agreement have been duly
authorized by all     

                                      -1-
<PAGE>

     
necessary corporate action. This Agreement has been duly executed and delivered
by the Company and Pulsar and constitutes the valid and binding obligation of
the Company and Pulsar, and the Representatives' Warrant Agreement, when
executed and delivered by the Company on the Closing Date, will be the valid and
binding obligation of the Company, enforceable in accordance with their
respective terms, subject, as to enforcement of remedies, to applicable
bankruptcy, insolvency, reorganization, moratorium and other laws affecting the
rights of creditors generally and the discretion of courts in granting equitable
remedies and except that enforceability of the indemnification provisions set
forth in Section 7 and the contribution provisions set forth in Section 8 of
this Agreement may be limited by the federal securities laws or public policy
underlying such laws.

               (iii) The execution, delivery and performance of this Agreement
by the Company and Pulsar and the Representatives' Warrant Agreement by the
Company, the consummation by the Company and Pulsar of the transactions herein
contemplated and by the Company of the transactions therein contemplated and the
compliance by the Company and Pulsar with the terms of this Agreement and by the
Company with the terms of the Representatives' Warrant Agreement do not, and
will not, with or without the giving of notice or the lapse of time, or both,
(A) result in a violation of the Certificate of Incorporation or Articles of
Incorporation, as the case may be, or By-Laws (or similar charter documents),
each as amended, of the Company or of any Subsidiary, (B) result in a breach of
or conflict with any terms or provisions of, or constitute a default under, or
result in the modification or termination of, or result in the creation or
imposition of any lien, security interest, charge or encumbrance upon any of the
properties or assets of the Company or any Subsidiary pursuant to any indenture,
mortgage, note, contract, commitment or other agreement or instrument to which
the Company or any Subsidiary is a party or by which the Company or any
Subsidiary or any of their respective properties or assets are or may be bound
or affected; (C) violate any existing applicable law, rule, regulation,
judgment, order or decree of any governmental agency or court, domestic or
foreign, having jurisdiction over the Company or any Subsidiary or any of their
respective properties or business; or (D) have any effect on any Permit
necessary for the Company or any Subsidiary to own or lease and operate their
respective properties or conduct their businesses or the ability of the Company
to make use thereof except in the case of clauses (ii), (iii) and (iv) where
such breach, conflict, default, violation, effect or other action or failure
would not have a material adverse effect on the business, financial condition or
results of operations of the Company and its Subsidiaries taken as a whole.     

                                      -2-
<PAGE>

     
               (iv)  To the best of Company Counsel's knowledge, no Permits of
any court or governmental agency or body (other than under the Act, the
Regulations and applicable state securities or Blue Sky laws) are required for
the valid authorization, issuance, sale and delivery of the Shares or the
Representatives' Warrants, and the consummation by the Company and Pulsar of the
transactions contemplated by this Agreement and by the Company of the
transactions contemplated by the Representatives' Warrant Agreement.

               (v)   The Registration Statement has become effective under the
Act; to the best of Company Counsel's knowledge, no stop order suspending the
effectiveness of the Registration Statement has been issued; and no proceedings
for that purpose have been instituted or are pending, threatened or contemplated
under the Act or applicable state securities laws.

               (vi)  The Registration Statement and the Prospectus, as of the
Effective Date, and each amendment or supplement thereto as of its effective or
issue date (except for the financial statements and other financial data
included therein or omitted therefrom, as to which Company Counsel need not
express an opinion) comply as to form in all material respects with the
requirements of the Act and Regulations and the conditions for use of a
registration statement on Form S-1 have been satisfied by the Company.

               (vii) The descriptions in the Registration Statement and the
Prospectus of statutes, regulations, government classifications, contracts and
other documents (including opinions of such counsel); and the response to Item
10 of Form S-1 have been reviewed by Company Counsel, and, based upon such
review, are accurate in all material respects and present fairly the information
required to be disclosed, and there are no material statutes, regulations or
government classifications, or, to the best of Company Counsel's knowledge,
material contracts or documents, of a character required to be described in the
Registration Statement or the Prospectus or to be filed as exhibits to the
Registration Statement, which are not so described or filed as required.

          None of the material provisions of the contracts or instruments
described above violates any existing applicable law, rule, regulation,
judgment, order or decree of any governmental agency or court having
jurisdiction over the Company or any Subsidiary or any of their assets or
businesses. To the best of Company counsel's knowledge, the Company is not in
default under any contract or agreement material to its business or under any
promissory note or other evidence of indebtedness for borrowed funds.

<PAGE>

     
               (viii) The outstanding Common Shares and outstanding options and
warrants to purchase Common Shares have been duly authorized and validly issued.
The outstanding Common Shares are fully paid and nonassessable. The outstanding
options and warrants to purchase Common Shares constitute the valid and binding
obligations of the Company, enforceable in accordance with their terms. None of
the outstanding Common Shares or options or warrants to purchase Common Shares
has been issued in violation of the preemptive rights of any shareholder of the
Company. None of the holders of the outstanding Common Shares is subject to
personal liability solely by reason of being such a holder. The offers and sales
of the outstanding Common Shares and outstanding options and warrants to
purchase Common Shares were at all relevant times either registered under the
Act and the applicable state securities or Blue Sky laws or exempt from such
registration requirements. The authorized Common Shares and outstanding options
and warrants to purchase Common Shares conform to the descriptions thereof
contained in the Registration Statement and Prospectus. To the best of Company
Counsel's knowledge, except as set forth in the Prospectus, no holders of any of
the Company's securities has any rights, "demand", "piggyback" or otherwise, to
have such securities registered under the Act.

               (ix)   The issuance and sale of the Shares and Warrant Shares
have been duly authorized and, when the Shares and Warrant Shares have been
issued and duly delivered against payment therefor as contemplated by this
Agreement and the Representatives' Warrant Agreement, respectively, the Shares
and the Warrant Shares will be validly issued, fully paid and nonassessable, and
the holders thereof will not be subject to personal liability solely by reason
of being such holders. Neither the Shares nor the Warrant Shares are subject to
preemptive rights of any shareholder of the Company. The certificates
representing the Shares are in proper legal form.

               (x)    The issuance and sale of the Representatives' Warrants
have been duly authorized and, when issued, paid for and delivered pursuant to
the terms of the Representatives' Warrant Agreement, they will constitute the
valid and binding obligations of the Company, enforceable as to the Company in
accordance with their terms. The Warrant Shares have been duly reserved for
issuance upon exercise of the Representatives' Warrants in accordance with the
provisions of the Representatives' Warrant Agreement. The Representatives'
Warrants conform to the descriptions thereof contained in the Registration
Statement and the Prospectus.

               (xi)   Upon delivery of the Offered Shares to the Underwriters
against payment therefor as provided in this Agreement, the Underwriters
(assuming they are bona fide purchasers     

                                      -4-
<PAGE>

     
within the meaning of the Uniform Commercial Code) will acquire good title to
the Offered Shares, free and clear of all liens, encumbrances, equities,
security interests and claims.

          (xii)  Assuming that the Representatives exercise the over-allotment
option to purchase any of the Optional Shares and make payment therefor in
accordance with the terms of this Agreement, upon delivery of the Optional
Shares so purchased to the Representatives hereunder, the Representatives
(assuming they are bona fide purchasers within the meaning of the Uniform
Commercial Code) will acquire good title to such Optional Shares, free and clear
of any liens, encumbrances, equities, security interests and claims.

          (xiii) To the best of Company Counsel's knowledge, there are no
claims, actions, suits, proceedings, arbitrations, investigations or inquiries
before any governmental agency, court or tribunal, foreign or domestic, or
before any private arbitration tribunal, pending or threatened against the
Company or any Subsidiary, or involving the Company's or any Subsidiary's
properties or businesses, other than as described in the Prospectus, such
description being accurate, and other than litigation incident to the kind of
business conducted by the Company which, individually and in the aggregate, is
not material.

          (xiv)  Each of the Company and of the Subsidiaries owns or possesses
adequate and enforceable rights to use all patents, patent applications,
trademarks, service marks, copyrights, rights, trade secrets, confidential
information, processes and formulations used or proposed to be used in the
conduct of its business as described in the Prospectus (collectively the
"Intangibles"); to the best of Company Counsel's knowledge, neither the Company
nor any Subsidiary has infringed or is infringing upon the rights of others with
respect to the Intangibles; and, to the best of Company Counsel's knowledge,
neither the Company nor any Subsidiary has received any notice that it has or
may have infringed upon, is infringing upon or is conflicting with the asserted
rights of others with respect to the Intangibles which might, singly or in the
aggregate, materially adversely affect its business, results of operations or
financial condition and such counsel is not aware of any licenses with respect
to the Intangibles which are required to be obtained by the Company or any
Subsidiary.

          (xv)   Company Counsel has participated in reviews and discussions in
connection with the preparation of the Registration Statement and the
Prospectus, and in the course of such reviews and discussions and such other
investigation as Company Counsel deemed necessary, no facts came to its
attention which lead it to believe that (A) the Registration Statement      

                                      -5-
<PAGE>

     
(except as to the financial statements and other financial data contained
therein, as to which Company Counsel need not express an opinion), on the
Effective Date, contained any untrue statement of a material fact required to be
stated therein or omitted to state any material fact required to be stated
therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading, or that (B) the
Prospectus (except as to the financial statements and other financial data
contained therein, as to which Company Counsel need not express an opinion)
contains any untrue statement of a material fact or omits to state any material
fact necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading.

          In rendering its opinion pursuant to this Section 6(b), Company
counsel may rely upon the certificates of government officials and officers of
the Company as to matters of fact, provided that Company shall state that they
have no reason to believe, and no not believe, that they are justified in
relying upon such opinions or such certificates of government officials and
officers of the Company as to matters of fact, as the case may be.

          The opinion letters delivered pursuant to this Section 6(b) shall
state that any opinion given therein qualified by the phrase "to the best of our
knowledge" is being given by Company Counsel after due investigation of the
matters therein discussed.

direction, to members of the selling group or underwriting syndicate and/or
their respective officers or partners (collectively, the "Designees"), in

<PAGE>
 
          2.   WARRANT CERTIFICATES.
               -------------------- 

          The warrant certificates delivered and to be delivered pursuant to
this Agreement (the "Warrant Certificates") shall be in the form set forth as
Exhibit A attached hereto and made a part hereof, with such appropriate
insertions, omissions, substitutions and other variations as required or
permitted by this Agreement.

          3.   EXERCISE OF WARRANTS.
               -------------------- 

               3.1  CASH EXERCISE. The Warrants initially are exercisable at a
                    -------------                                             
price of $______ per Share [165% of the initial offering price of the Public
Shares], payable in cash or by check to the order of the Company, or any
combination thereof, subject to adjustment as provided in Article 8 hereof. Upon
surrender of a Warrant Certificate with the annexed Form of Election to Purchase
duly executed, together with payment of the Exercise Price (as hereinafter
defined) for the Shares purchased, at the Company's principal offices in
California (currently located at 2030 Main Street, Suite 1250, Irvine,
California 92610) the registered holder of a Warrant Certificate ("Holder" or
"Holders") shall be entitled to receive a certificate or certificates for the
Shares so purchased. The purchase rights represented by each Warrant Certificate
are exercisable at the option of the Holder thereof, in whole or in part (but
not as to fractional shares of the Common Stock). In the case of the purchase of
less than all the Shares purchasable under any Warrant Certificate, the Company
shall cancel said Warrant Certificate upon the surrender thereof and shall
execute and deliver a new Warrant Certificate of like tenor for the balance of
the Shares purchasable thereunder.

               3.2  CASHLESS EXERCISE. At any time during the Warrant Exercise
                    -----------------                                         
Term, the Holder may, at the Holder's option, exchange, in whole or in part, the
Warrants represented by such Holder's Warrant Certificate (a "Warrant
Exchange"), into the number of Shares determined in accordance with this Section
3.2, by surrendering such Warrant Certificate at the principal office of the
Company or at the office of its transfer agent, accompanied by a notice stating
such Holder's intent to effect such exchange, the number of Warrants to be so
exchanged and the date on which the Holder requests that such Warrant Exchange
occur (the "Notice of Exchange"). The Warrant Exchange shall take place on the
date specified in the Notice of Exchange or, if later, the date the Notice of
Exchange is received by the Company (the "Exchange Date"). Certificates for the
Shares issuable upon such Warrant Exchange and, if applicable, a new Warrant
Certificate of like tenor representing the Warrants which were subject to the
surrendered Warrant Certificate and not included in the Warrant Exchange, shall
be issued as of the Exchange Date and delivered to the Holder within three (3)
business days following the Exchange Date. In connection with any Warrant
Exchange, the Holder shall be entitled to subscribe for and acquire (i) the
number of Shares (rounded to the next highest integer) which would, but for the
Warrant Exchange, then be issuable pursuant to the provision of Section 3.1
<PAGE>
 
above upon the exercise of the Warrants specified by the Holder in its Notice of
Exchange (the "Total Number") less (ii) the number of Shares equal to the
quotient obtained by dividing (a) the product of the Total Number and the
existing Exercise Price (as hereinafter defined) by (b) the Market Price (as
hereinafter defined) of a Public Share on the day preceding the Warrant
Exchange. "Market Price" at any date shall be deemed to be the last reported
sale price, or, in case no such reported sales takes place on such day, the
average of the last reported sale prices for the last three (3) trading days, in
either case as officially reported by the principal securities exchange on which
the Common Stock is listed or admitted to trading or as reported in the Nasdaq
National Market System, or, if the Common Stock is not listed or admitted to
trading on any national securities exchange or quoted on the Nasdaq National
Market System, the closing bid price as furnished by (i) the National
Association of Securities Dealers, Inc. through Nasdaq or (ii) a similar
organization if Nasdaq is no longer reporting such information.

          4.   ISSUANCE OF CERTIFICATES.
               ------------------------ 

          Upon the exercise of the Warrants, the issuance of certificates for
the Shares purchased shall be made forthwith (and in any event within three (3)
business days thereafter) without charge to the Holder thereof including,
without limitation, any tax which may be payable in respect of the issuance
thereof, and such certificates shall (subject to the provisions of Article 5
hereof) be issued in the name of, or in such names as may be directed by, the
Holder thereof; provided, however, that the Company shall not be required to pay
any tax which may be payable in respect of any transfer involved in the issuance
and delivery of any such certificates in a name other than that of the Holder
and the Company shall not be required to issue or deliver such certificates
unless or until the person or persons requesting the issuance thereof shall have
paid to the Company the amount of such tax or shall have established to the
satisfaction of the Company that such tax has been paid.

          The Warrant Certificates and the certificates representing the Shares
shall be executed on behalf of the Company by the manual or facsimile signature
of the present or any future Chairman or Vice Chairman of the Board of Directors
or President or Vice President of the Company under its corporate seal
reproduced thereon, attested to by the manual or facsimile signature of the
present or any future Secretary or Assistant Secretary of the Company. Warrant
Certificates shall be dated the date of execution by the Company upon initial
issuance, division, exchange, substitution or transfer.

          The Warrant Certificates and, upon exercise of the Warrants, in part
or in whole, certificates representing the Shares shall bear a legend
substantially similar to the following:
<PAGE>
 
     "The securities represented by this certificate and the other
     securities issuable upon exercise thereof have not been
     registered for purposes of public distribution under the
     Securities Act of 1933, as amended (the "Act"), and may not be
     offered or sold except (i) pursuant to an effective registration
     statement under the Act, (ii) to the extent applicable, pursuant
     to Rule 144 under the Act (or any similar rule under such Act
     relating to the disposition of securities), or (iii) upon the
     delivery by the holder to the Company of an opinion of counsel,
     reasonably satisfactory to counsel to the Company, stating that
     an exemption from registration under such Act is available."

          5.   RESTRICTION ON TRANSFER OF WARRANTS.
               ----------------------------------- 

          The Holder of a Warrant Certificate, by the Holder's acceptance
thereof, covenants and agrees that the Warrants are being acquired as an
investment and not with a view to the distribution thereof, and that the
Warrants may not be sold, transferred, assigned, hypothecated or otherwise
disposed of, in whole or in part, for a period of one (1) year from the date
hereof, except to the Designees.

          6.   PRICE.
               ----- 

               6.1  INITIAL AND ADJUSTED EXERCISE PRICE.  The initial exercise
                    -----------------------------------                       
price of each Warrant shall be $____ per Share [165% of the initial offering
price of the Public Shares].  The adjusted exercise price per Share shall be the
price which shall result from time to time from any and all adjustments of the
initial exercise price in accordance with the provisions of Article 8 hereof.

               6.2  EXERCISE PRICE.  The term "Exercise Price" herein shall mean
                    --------------                                              
the initial exercise price or the adjusted exercise price, depending upon the
context.

          7.   REGISTRATION RIGHTS.
               ------------------- 

               7.1  REGISTRATION UNDER THE SECURITIES ACT OF 1933. None of the
                    ---------------------------------------------             
Warrants or Shares have been registered for purposes of public distribution
under the Securities Act of 1933, as amended (the "Act").

               7.2  REGISTRABLE SECURITIES.  As used herein the term 
                    ----------------------                          
"Registrable Security" means each of the Shares and any shares of Common Stock
issued upon any stock split or stock dividend in respect of such Shares;
provided, however, that with respect to any particular Registrable Security,
such security shall cease to be a Registrable Security when, as of the date of
determination, (i) it has been effectively registered under the Act and disposed
of pursuant thereto, (ii) registration under the Act is no longer required for
the subsequent public distribution of such security or 
<PAGE>
 
(iii) it has ceased to be outstanding. The term "Registrable Securities" means
any and/or all of the securities falling within the foregoing definition of a
"Registrable Security." In the event of any merger, reorganization,
consolidation, recapitalization or other change in corporate structure affecting
the Common Stock, such adjustment shall be made in the definition of
"Registrable Security" as is appropriate in order to prevent any dilution or
enlargement of the rights granted pursuant to this Article 7.

               7.3  PIGGYBACK REGISTRATION.  If, at any time during the seven
                    ----------------------                        
years following the effective date of the Public Offering, the Company proposes
to prepare and file one or more post-effective amendments to the registration
statement filed in connection with the Public Offering or any new registration
statement or post-effective amendments thereto covering equity or debt
securities of the Company, or any such securities of the Company held by its
shareholders (in any such case, other than in connection with a merger,
acquisition or pursuant to Form S-8 or successor form), (for purposes of this
Article 7, collectively, the "Registration Statement"), it will give written
notice of its intention to do so by registered mail ("Notice"), at least thirty
(30) days prior to the filing of each such Registration Statement, to all
holders of the Registrable Securities. Upon the written request of such a holder
(a "Requesting Holder"), made within twenty (20) days after receipt of the
Notice, that the Company include any of the Requesting Holder's Registrable
Securities in the proposed Registration Statement, the Company shall, as to each
such Requesting Holder, use its best efforts to effect the registration under
the Act of the Registrable Securities which it has been so requested to register
("Piggyback Registration"), at the Company's sole cost and expense and at no
cost or expense to the Requesting Holders (except as provided in Section 7.5(b) 
hereof); provided, however, that if, in the written opinion of the Company's 
managing underwriter, if any, for such offering, the inclusion of all or a 
portion of the Registrable Securities requested to be registered, when added to 
the securities being registered by the Company or the selling shareholder(s), 
will exceed the maximum amount of the Company's securities which can be marketed
(i) at a price reasonably related to their then current market value, or (ii) 
without otherwise materially adversely affecting the entire offering, then the 
Company may exclude from such offering all or a portion of the Registrable 
Securities which it has been requested to register.

               Notwithstanding the provisions of this Section 7.3, the Company
shall have the right at any time after it shall have given written notice
pursuant to this Section 7.3 (irrespective of whether any written request for
inclusion of Registrable Securities shall have already been made) to elect not
to file any such proposed Registration Statement, or to withdraw the same after
the filing but prior to the effective date thereof.

               7.4  DEMAND REGISTRATION.
                    ------------------- 

                    (a)  At any time during the Warrant Exercise Term, any
"Majority Holder" (as such term is defined in Section 7.4.(c) below) of the
Registrable Securities shall have the right (which right is in addition to the
piggyback registration rights provided for under Section 7.3 hereof),
exercisable by written notice to the Company (the "Demand Registration
Request"), to have the Company prepare and file with the Securities and Exchange
Commission (the "Commission"), on one occasion, at the sole expense of the
Company (except as provided in Section 7.5.(b) hereof), a Registration Statement
and such other documents, including a prospectus, as may be necessary (in the
opinion of both counsel for 
<PAGE>
 
the Company and counsel for such Majority Holder), in order to comply with the
provisions of the Act, so as to permit a public offering and sale of the
Registrable Securities by the holders thereof. The Company shall use its best
efforts to cause the Registration Statement to become effective under the Act,
so as to permit a public offering and sale of the Registrable Securities by the
holders thereof. Once effective, the Company will use its best efforts to
maintain the effectiveness of the Registration Statement until the earlier of
(i) the date that all of the Registrable Securities have been sold or (ii) the
date that the holders of the Registrable Securities receive an opinion of
counsel to the Company that all of the Registrable Securities may be freely
traded (without limitation or restriction as to quantity or timing and without
registration under the Act) under Rule 144(k) promulgated under the Act or
otherwise. Notwithstanding the foregoing, if (i) in the good faith judgment of 
the Board of Directors of the Company, such registration would be materially 
detrimental to the Company, and the Board of Directors concludes, as a result, 
that it is essential to defer the filing of such Registration Statement at such 
time, and (ii) the Company shall furnish to such Holders a certificate signed by
the Chief Executive Officer of the Company stating that, in the good faith 
judgment of the Board of Directors of the Company, it would be materially 
detrimental to the Company for such Registration Statement to be filed in the 
near future and that it is, therefore, essential to defer the filing of such 
Registration Statement, then the Company shall have the right to defer such 
filing for a period of not more than ninety (90) days after receipt of the 
Demand Registration Request, and provided further, that the Company shall not 
defer its obligation in this manner more than two (2) times or for more than an
aggregate of one hundred and twenty (120) days in any rolling twelve (12) month 
period and should the Company delay the filing of the Registration Statement 
upon receipt of a Demand Registration Request, the exercise period of the 
Warrants shall be extended, for each delay, for a period of time equal in length
to the delay in registration.

                    (b)  The Company covenants and agrees to give written notice
of any Demand Registration Request to all holders of the Registrable Securities
within ten (10) business days from the date of the Company's receipt of any such
Demand Registration Request. After receiving notice from the Company as provided
in this Section 7.4(b), holders of Registrable Securities may request the
Company to include their Registrable Securities in the Registration Statement to
be filed pursuant to Section 7.4(a) hereof by notifying the Company of their
decision to have such securities included within ten (10) days of their receipt
of the Company's notice.

                    (c)  The term "Majority Holder" as used in Section 7.4
hereof shall mean any holder or any combination of holders of Registrable
Securities, if included in such holders' Registrable Securities are that
aggregate number of Shares (including Shares already issued and Shares issuable
pursuant to the exercise of outstanding Warrants) as would constitute a majority
of the aggregate number of Shares (including Shares already issued and Shares
issuable pursuant to the exercise of outstanding Warrants) included in all the
Registrable Securities.

               7.5. COVENANTS OF THE COMPANY WITH RESPECT TO REGISTRATION.  The
                    -----------------------------------------------------
Company covenants and agrees as follows:

                    (a)  In connection with any registration under Section 7.4
hereof, the Company shall file the Registration Statement as expeditiously as
possible, but in any event no later than thirty (30) business days following
receipt of any demand therefor, shall use its best efforts to have any such
Registration Statement declared effective at the earliest possible time, and
shall furnish each holder of Registrable Securities such number of prospectuses
as shall reasonably be requested.

                    (b)  The Company shall pay all costs, fees and expenses
(other than underwriting fees, discounts and nonaccountable expense allowances
applicable to the Registrable Securities and the fees and expenses of counsel
retained by the 
<PAGE>
 
holders of the Registrable Securities) in connection with all Registration
Statements filed pursuant to Sections 7.3. and 7.4.(a) hereof including, without
limitation, the Company's legal and accounting fees, printing expenses, and blue
sky fees and expenses.

                    (c)  The Company will take all necessary action which may be
required in qualifying or registering the Registrable Securities included in the
Registration Statement for offering and sale under the securities or blue sky
laws of such states as are reasonably requested by the holders of such
securities, provided that the Company shall not be obligated to execute or file
any general consent to service of process or to qualify as a foreign corporation
to do business under the laws of any such jurisdiction.

                    (d)  The Company shall indemnify any holder of the
Registrable Securities to be sold pursuant to any Registration Statement and any
underwriter or person deemed to be an underwriter under the Act and each person,
if any, who controls such holder or underwriter or person deemed to be an
underwriter within the meaning of Section 15 of the Act or Section 20(a) of the
Securities Exchange Act of 1934, as amended ("Exchange Act"), against all loss,
claim, damage, expense or liability (including all expenses reasonably incurred
in investigating, preparing or defending against any claim whatsoever) to which
any of them may become subject under the Act, the Exchange Act or otherwise,
arising from such registration statement to the same extent and with the same
effect as the provisions pursuant to which the Company has agreed to indemnify
the Underwriters contained in Section 7 of the Underwriting Agreement and to
provide for just and equitable contribution as set forth in Section 8 of the
Underwriting Agreement.

                    (e)  Any holder of Registrable Securities to be sold
pursuant to a Registration Statement, and such Holder's successors and assigns,
shall severally, and not jointly, indemnify, the Company, its officers and
directors and each person, if any, who controls the Company within the meaning
of Section 15 of the Act or Section 20(a) of the Exchange Act, against all loss,
claim, damage or expense or liability (including all expenses reasonably
incurred in investigating, preparing or defending against any claim whatsoever)
to which they may become subject under the Act, the Exchange Act or otherwise,
arising from information furnished by or on behalf of such Holder, or such
Holder's successors or assigns, for specific inclusion in such Registration
Statement to the same extent and with the same effect as the provisions pursuant
to which the Underwriters have agreed to indemnify the Company contained in
Section 7 of the Underwriting Agreement and to provide for just and equitable
contribution as set forth in Section 8 of the Underwriting Agreement.

                    (f)  Nothing contained in this Agreement shall be construed
as requiring any Holder to exercise the Warrants held 
<PAGE>
 
by such Holder prior to the initial filing of any Registration Statement or the
effectiveness thereof.

                    (g)  The Company shall promptly deliver copies of all
correspondence between the Commission and the Company, its counsel or auditors
and all memoranda relating to discussions with the Commission or its staff with
respect to the Registration Statement to each Holder of Registrable Securities
included for registration in such Registration Statement pursuant to Section 7.3
or Section 7.4 hereof that requests such correspondence and memoranda and to the
managing underwriter, if any, of the offering in connection with which such
Holder's Registrable Securities are being registered and shall permit each such
Holder and managing underwriter to do such investigation, upon reasonable
advance notice, with respect to information contained in or omitted from the
Registration Statement as it deems reasonably necessary to comply with
applicable securities laws or rules of the National Association of Securities
Dealers, Inc. Such investigation shall include access to books, records and
properties and opportunities to discuss the business of the Company with its
officers and independent auditors, all to such reasonable extent and at such
reasonable times and as often as any such Holder or managing underwriter shall
reasonably request.

          8.   ADJUSTMENTS OF EXERCISE PRICE AND NUMBER OF SHARES.
               -------------------------------------------------- 

               8.1  COMPUTATION OF ADJUSTED PRICE.  In case the Company shall at
                    -----------------------------                               
any time after the date hereof pay a dividend in shares of Common Stock or make
a distribution in shares of Common Stock, then upon such dividend or
distribution, the Exercise Price in effect immediately prior to such dividend or
distribution shall forthwith be reduced to a price determined by dividing:

                    (a)  an amount equal to the total number of shares of Common
Stock outstanding immediately prior to such dividend or distribution multiplied
by the Exercise Price in effect immediately prior to such dividend or
distribution, by

                    (b)  the total number of shares of Common Stock outstanding
immediately after such issuance or sale.

               For the purposes of any computation to be made in accordance with
the provisions of this Section 8.1, the Common Stock issuable by way of dividend
or other distribution on any stock of the Company shall be deemed to have been
issued immediately after the opening of business on the date following the date
fixed for the determination of stockholders entitled to receive such dividend or
other distribution.

               8.2  SUBDIVISION AND COMBINATION. In case the Company shall at 
                    ---------------------------                              
any time subdivide or combine the outstanding shares of Common Stock, the
Exercise Price shall forthwith be 
<PAGE>
 
proportionately decreased in the case of subdivision or increased in the case of
combination.

               8.3  ADJUSTMENT IN NUMBER OF SHARES. Upon each adjustment of the
                    ------------------------------                             
Exercise Price pursuant to the provisions of this Article 8, the number of
Shares issuable upon the exercise of each Warrant shall be adjusted to the
nearest full number by multiplying a number equal to the Exercise Price in
effect immediately prior to such adjustment by the number of Shares issuable
upon exercise of the Warrants immediately prior to such adjustment and dividing
the product so obtained by the adjusted Exercise Price.

               8.4  RECLASSIFICATION, CONSOLIDATION, MERGER, ETC. In case of any
                    ---------------------------------------------               
reclassification or change of the outstanding shares of Common Stock (other than
a change in par value to no par value, or from no par value to par value, or as
a result of a subdivision or combination), or in the case of any consolidation
of the Company with, or merger of the Company into, another corporation (other
than a consolidation or merger in which the Company is the surviving corporation
and which does not result in any reclassification or change of the outstanding
shares of Common Stock, except a change as a result of a subdivision or
combination of such shares or a change in par value, as aforesaid), or in the
case of a sale or conveyance to another corporation of the property of the
Company as an entirety, the Holders shall thereafter have the right to purchase
the kind and number of shares of stock and other securities and property
receivable upon such reclassification, change, consolidation, merger, sale or
conveyance as if the Holders were the owners of the shares of Common Stock
underlying the Warrants immediately prior to any such events at a price equal to
the product of (x) the number of shares of Common Stock issuable upon exercise
of the Holder's Warrants and (y) the Exercise Price in effect immediately prior
to the record date for such reclassification, change, consolidation, merger,
sale or conveyance as if such Holders had exercised the Warrants.
 
               8.5  DETERMINATION OF OUTSTANDING SHARES OF COMMON STOCK. The 
                    ---------------------------------------------------
number of shares of Common Stock at any one time outstanding shall include the
aggregate number of shares of Common Stock issued and the aggregate number of
shares of Common Stock issuable upon the exercise of options, rights, warrants
and upon the conversion or exchange of convertible or exchangeable securities.

               8.6  DIVIDENDS AND OTHER DISTRIBUTIONS WITH RESPECT TO
                    -------------------------------------------------
OUTSTANDING SECURITIES. In the event that the Company shall at any time prior to
- ----------------------                                                          
the exercise of all Warrants make any distribution of its assets to holders of
its Common Stock as a liquidating or a partial liquidating dividend, then the
holder of Warrants who exercises its Warrants after the record date for the
determination of those holders of Common Stock entitled to such distribution of
assets as a liquidating or partial liquidating dividend shall be entitled to
receive for the Exercise Price per Warrant, in addition to each share of Common
Stock, the amount of 
<PAGE>
 
such distribution (or, at the option of the Company, a sum equal to the value of
any such assets at the time of such distribution as determined by the Board of
Directors of the Company in good faith) which would have been payable to such
holder had he been the holder of record of the Common Stock receivable upon
exercise of his Warrant on the record date for the determination of those
entitled to such distribution. At the time of any such dividend or distribution,
the Company shall make appropriate reserves to ensure the timely performance of
the provisions of this Subsection 8.6.

               8.7  SUBSCRIPTION RIGHTS FOR SHARES OF COMMON STOCK OR OTHER
                    -------------------------------------------------------
SECURITIES. If the Company or an affiliate of the Company shall at any time 
- ----------
after the date hereof and prior to the exercise of all the Warrants issue any 
rights, warrants or options to subscribe for shares of Common Stock or any
other securities of the Company or of such affiliate to all the shareholders of
the Company, the Holders of unexercised Warrants on the record date set by the
Company or such affiliate in connection with such issuance of rights, warrants
or options shall be entitled, in addition to the shares of Common Stock or other
securities receivable upon the exercise of the Warrants, to receive such rights,
warrants or options that such Holders would have been entitled to receive had
they been, on such record date, the holders of record of the number of whole
shares of Common Stock then issuable upon exercise of their outstanding Warrants
(assuming for purposes of this Section 8.7, that the exercise of the Warrants
is permissible immediately upon issuance).

          9.   EXCHANGE AND REPLACEMENT OF WARRANT CERTIFICATES.
               ------------------------------------------------ 

          Each Warrant Certificate is exchangeable without expense, upon the
surrender thereof by the registered Holder at the principal executive office of
the Company, for a new Warrant Certificate of like tenor and date representing
in the aggregate the right to purchase the same number of Shares in such
denominations as shall be designated by the Holder thereof at the time of such
surrender.

          Upon receipt by the Company of evidence reasonably satisfactory to it
of the loss, theft, destruction or mutilation of any Warrant Certificate, and,
in case of loss, theft or destruction, of indemnity or security reasonably
satisfactory to it, and reimbursement to the Company of all reasonable expenses
incidental thereto, and upon surrender and cancellation of the Warrant
Certificate, if mutilated, the Company will make and deliver a new Warrant
Certificate of like tenor, in lieu thereof.

          10.  ELIMINATION OF FRACTIONAL INTERESTS.
               ----------------------------------- 

          The Company shall not be required to issue certificates representing
fractions of Shares, nor shall it be required to issue 
<PAGE>
 
scrip or pay cash in lieu of fractional interests, it being the intent of the
parties that all fractional interests shall be eliminated by rounding any
fraction up to the nearest whole number of Shares.

          11.  RESERVATION AND LISTING OF SECURITIES.
               ------------------------------------- 

          The Company shall at all times reserve and keep available out of its
authorized shares of Common Stock, solely for the purpose of issuance upon the
exercise of the Warrants, such number of shares of Common Stock as shall be
issuable upon the exercise thereof. The Company covenants and agrees that, upon
exercise of the Warrants and payment of the Exercise Price therefor, all Shares
issuable upon such exercise shall be duly and validly issued, fully paid, non-
assessable and not subject to the preemptive rights of any shareholder. As long
as the Warrants shall be outstanding, the Company shall use its best efforts to
cause all shares of Common Stock issuable upon the exercise of the Warrants to
be listed on the Nasdaq National Market or listed on such national securities
exchanges as the Common Stock is listed at such time.

          12.  NOTICES TO WARRANT HOLDERS.
               -------------------------- 

          Nothing contained in this Agreement shall be construed as conferring
upon the Holder or Holders the right to vote or to consent or to receive notice
as a shareholder in respect of any meetings of shareholders for the election of
directors or any other matter, or as having any rights whatsoever as a
shareholder of the Company. If, however, at any time prior to the expiration of
the Warrants and their exercise, any of the following events shall occur:

               (a)  the Company shall take a record of the holders of its shares
of Common Stock for the purpose of entitling them to receive a dividend or
distribution payable otherwise than in cash, or a cash dividend or distribution
payable otherwise than out of current or retained earnings, as indicated by the
accounting treatment of such dividend or distribution on the books of the
Company; or

               (b)  the Company shall offer to all the holders of its Common
Stock any additional shares of capital stock of the Company or securities
convertible into or exchangeable for shares of capital stock of the Company, or
any option, right or warrant to subscribe therefor; or

               (c)  a dissolution, liquidation or winding up of the Company
(other than in connection with a consolidation or merger) or a sale of all or
substantially all of its property, assets and business as an entirety shall be
proposed; or

               (d)  reclassification or change of the outstanding shares of
Common Stock (other than a change in par value to no par value, or from no par
value to par value, or as a result of a 
<PAGE>
 
subdivision or combination), consolidation of the Company with, or merger of the
Company into, another corporation (other than a consolidation or merger in which
the Company is the surviving corporation and which does not result in any
reclassification or change of the outstanding shares of Common Stock, except a
change as a result of a subdivision or combination of such shares or a change in
par value, as aforesaid), or a sale or conveyance to another corporation of the
property of the Company as an entirety is proposed; or

               (e)  The Company or an affiliate of the Company shall propose to
issue any rights to subscribe for shares of Common Stock or any other securities
of the Company or of such affiliate to all the shareholders of the Company;
then, in any one or more of said events, the Company shall give written notice
to the Holder or Holders of such event at least fifteen (15) days prior to the
date fixed as a record date or the date of closing the transfer books for the
determination of the shareholders entitled to such dividend, distribution,
convertible or exchangeable securities or subscription rights, options or
warrants, or entitled to vote on such proposed dissolution, liquidation, winding
up or sale. Such notice shall specify such record date or the date of closing
the transfer books, as the case may be. Failure to give such notice or any
defect therein shall not affect the validity of any action taken in connection
with the declaration or payment of any such dividend or distribution, or the
issuance of any convertible or exchangeable securities or subscription rights,
options or warrants, or any proposed dissolution, liquidation, winding up or
sale.

          13.  NOTICES.
               ------- 

          All notices, requests, consents and other communications hereunder
shall be in writing and shall be deemed to have been duly made when delivered,

This Warrant Certificate certifies that _______________ ____________ or

Inc. (the "Warrant Agreement"). Payment of the Exercise Price may be made in 
cash, or by certified or official bank check in New York Clearing House funds 
payable to the order of the Company, or any combination thereof.

No Warrant may be exercised after 5:00 P.M., New York City time, on the
Expiration Date, at which time all Warrants evidenced hereby, unless exercised
prior thereto, shall thereafter be void.

The Warrants evidenced by this Warrant Certificate are part of a duly authorized
issue of Warrants issued pursuant to the Warrant Agreement, which Warrant
Agreement is hereby incorporated by reference in and made a part of this
instrument and is hereby referred to in a description of the rights, limitation
of rights, 
<PAGE>
 
obligations, duties and immunities thereunder of the Company and the holders
(the words "holders" or "holder" meaning the registered holders or registered
holder) of the Warrants.

The Warrant Agreement provides that upon the occurrence of certain events, the
Exercise Price and/or number of the Company's securities issuable thereupon may,
subject to certain conditions, be adjusted. In such event, the Company will, at
the request of the holder, issue a new Warrant Certificate evidencing the
adjustment in the Exercise Price and the number and/or type of securities
issuable upon the exercise of the Warrants; provided, however, that the failure
of the Company to issue such new Warrant Certificates shall not in any way
change, alter, or otherwise impair, the rights of the holder as set forth in the
Warrant Agreement.

Upon due presentment for registration of transfer of this Warrant Certificate at
an office or agency of the Company, a new Warrant Certificate or Warrant
Certificates of like tenor and evidencing in the aggregate a like number of
Warrants shall be issued to the transferee(s) in exchange for this Warrant
Certificate, subject to the limitations provided herein and in the Warrant
Agreement, without any charge except for any tax or other governmental charge
imposed in connection therewith.

Upon the exercise of less than all of the Warrants evidenced by this
Certificate, the Company shall forthwith issue to the holder hereof a new
Warrant Certificate representing such number of unexercised Warrants.

The Company may deem and treat the registered holder(s) hereof as the absolute
owner(s) of this Warrant Certificate (notwithstanding any notation of ownership
or other writing hereon made by anyone), for the purpose of any exercise hereof,
and of any distribution to the holder(s) hereof, and for all other purposes, and
the Company shall not be affected by any notice to the contrary.

All terms used in this Warrant Certificate which are defined in the Warrant
Agreement shall have the meanings assigned to them in the Warrant Agreement.

IN WITNESS WHEREOF, the Company has caused this Warrant Certificate to be duly
executed under its corporate seal.

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

    
THIS COMMERCIAL SECURITY AGREEMENT is entered into between PULSAR DATA SYSTEMS,
INC. (referred to below as "Grantor"); and WILMINGTON TRUST COMPANY (referred to
below as "Lender"). For valuable consideration, Grantor grants to Lender a
security interest in the Collateral to secure the Indebtedness and agrees that
Lender shall have the rights stated in this Agreement with respect to the
Collateral, in addition to all other rights which Lender may have by law.     


DEFINITIONS.  The following words shall have the following meanings when used in
this Agreement. Terms not otherwise defined in this Agreement shall have the
meanings attributed to such terms in the Uniform Commercial Code. All references
to dollar amounts shall mean amounts in lawful money of the United States of
America.

     AGREEMENT.  The word "Agreement" means this Commercial Security Agreement,
     as this Commercial Security Agreement may be amended or modified from time
     to time, together with all exhibits and schedules attached to this
     Commercial Security Agreement from time to time.

     COLLATERAL.  The word "Collateral" means the following described property
     of Grantor, whether now owned or hereafter acquired, whether now existing
     or hereafter arising, and wherever located:

          All inventory, accounts, general intangibles and equipment, together
          with the following specifically described property:

               ALL RECORDS OF ANY KIND RELATING TO ANY OF THE FOREGOING; ALL
          PROCEEDS RELATING TO ANY OF THE FOREGOING (INCLUDING INSURANCE,
          GENERAL INTANGIBLES AND OTHER ACCOUNTS PROCEEDS).
<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:

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

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 additional rent shall be
payable as and when 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

     1995, in the principal amount of $22,000,000.00 from Grantor to Lender,

OBLIGATIONS OF GRANTOR.  Grantor warrants and covenants to Lender as follows:

     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

                                  (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 
<PAGE>
 
07-24-1995               COMMERCIAL SECURITY AGREEMENT                    Page 5
                                  (Continued)

     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
<PAGE>
 
07-24-1995               COMMERCIAL SECURITY AGREEMENT                    Page 8
                                  (Continued)

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. 

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

     DEFAULT ON INDEBTEDNESS.  Failure of Grantor to make any payment when due
     on the Indebtedness.

     OTHER DEFAULTS. Failure of Grantor to comply with or to perform any other
     term, obligation, covenant or condition contained in this Agreement or in
     any of the Related Documents or in any other agreement between Lender and
     Grantor.
     
     INSOLVENCY. The dissolution or termination of Grantor's existence as a
     going business, the insolvency of Grantor, the appointment of a receiver
     for any part of Grantor's property, any assignment for the benefit of
     creditors, any type of creditor workout, or the commencement of any
     proceeding under any bankruptcy laws by or against Grantor.

     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 Grantor or by any
     governmental agency against the Collateral or any other collateral
     securing the Indebtedness.  This includes a garnishment of any of Grantor's
     deposit accounts with Lender.

     EVENTS AFFECTING GRANTOR. Any of the preceding events occurs with
     respect to any Guarantor of any of the Indebtedness or such Guarantor
     dies or becomes incompetent.

     ADVERSE CHANGE.  A material adverse change occurs in Grantor's
     financial condition or Lender believes the prospect of payment or
     performance of the Indebtedness is impaired.

RIGHTS AND REMEDIES ON DEFAULT.  If an Event of Default occurs under this
Agreement, at any time thereafter, Lender shall have all the rights of a secured
party under the Maryland Uniform Commercial Code.  In addition and without
limitation, Lender may exercise any one or more of the following rights and
remedies:

     ACCELERATE INDEBTEDNESS.  Lender may Declare the entire Indebtedness,
     including any prepayment penalty which Grantor would be required to pay,
     immediately due and payable, without notice.

     ASSEMBLE COLLATERAL.  Lender may require Grantor to deliver to Lender
     all or any portion of the Collateral and any and all certificates of title
     and other documents relating to the Collateral.  Lender may require Grantor
     to assemble the Collateral and make it available to Lender at a place to be
     designated by Lender.  Lender also shall full power to enter upon the
     property of Grantor to take possession of and remove the Collateral. If
     the
<PAGE>
 
07-24-1995               COMMERCIAL SECURITY AGREEMENT                    Page 9
                                  (Continued)

     Collateral contains other goods not covered by this Agreement at the time
     of repossession, grantor agrees Lender may take such other goods, provided
     that Lender makes reasonable efforts to return them to Grantor after
     repossession.

     Sell THE COLLATERAL.  Lender shall have full power to sell, lease, 
     transfer, or otherwise deal with the Collateral or proceeds thereof in its
     own name or that of Grantor. Lender may sell the Collateral at public
     auction or private sale. Unless the Collateral threatens to decline
     speedily in value or is of a type customarily sold on a recognized market,
     Lender will give Grantor reasonable notice of the time after which any
     private sale or any other intended disposition of the Collateral is to be
     made. The requirements of reasonable notice shall be met if such notice is
     given at least ten (10) days before the time of the sale or disposition.
     All expenses relating to the disposition of the Collateral, including
     without limitation the expenses of retaking, holding, insuring, preparing
     for sale and selling the Collateral, shall become a part of the
     Indebtedness secured by this Agreement and shall be payable on demand, with
     interest at the Note rate from date of expenditure until repaid.

     APPOINT RECEIVER.  To the extent permitted by applicable law, Lender shall
     have the following rights and remedies regarding the appointment of a
     receiver: (a) Lender may have a receiver appointed as a matter of right,
     (b) the receiver may be an employee of Lender and may serve without bond,
     and (c) all fees of the receiver and his or her attorney shall become part
     of the Indebtedness secured by this Agreement and shall be payable on
     demand, with interest at the Note rate from date of expenditure until
     repaid.

COLLECT REVENUES, APPLY ACCOUNTS.  Lender, either itself or through a receiver,
may collect the payments, rents, income and revenues from the Collateral. Lender
may at any time in its discretion transfer any Collateral into its own name or
that of its nominee and receive the payments, rents, income and revenues
therefrom and hold the same as security for the Indebtedness or apply it to
payment of the Indebtedness in such order of preference as Lender may determine.
Insofar as the Collateral consists of accounts, general intangibles, insurance
policies, instruments, chattel paper, choses in action, or similar property,
Lender may demand, collect, receipt for, settle, compromise, adjust, sue for,
foreclose, or realize on the Collateral as Lender may determine, whether or
not indebtedness or Collateral is then due. For these purposes, Lender may, on
behalf of and in the name of Grantor, receive, open and dispose of mail
addressed to Grantor; change any address to which mail and payments are to be
sent; and endorse notes, checks, drafts, money orders, documents of title,
instruments and items pertaining to payment, shipment, or storage of any
Collateral. To facilitate collection, Lender may notify account debtors and
obligors on any Collateral to make payments directly to Lender.

OBTAIN DEFICIENCY.  If Lender chooses to sell any or all of the Collateral,
Lender may obtain a judgment against Grantor for any deficiency remaining on the
Indebtedness due to Lender after application of all amounts received from the
exercise of the rights provided in this Agreement.  Grantor shall be liable for
a deficiency even if the transaction described in this subsection is a sale of
accounts or chattel paper.

                                  (Continued)

OTHER RIGHTS AND REMEDIES.  Lender shall have all the rights and remedies of a
secured creditor under the provisions of the Uniform Commercial Code, as may be
amended from time to time.  In addition, Lender shall have and may exercise any
or all other rights and remedies it may have available at law, in equity, or
otherwise.

CUMULATIVE REMEDIES.  All of Lender's rights and remedies, whether evidenced by
this Agreement  or the Related Documents or by any other writing, 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
Grantor under this Agreement, after Grantor's failure to perform, shall not
affect Lender's right to declare a default and to exercise its remedies.

OF ALL CLAIMS AGAINST ALL PARTIES TO SUCH ACTIONS OR PROCEEDINGS. THIS WAIVER IS
KNOWINGLY, WILLINGLY AND VOLUNTARILY MADE BY LENDER AND GRANTOR, AND LENDER AND

CAPTION HEADINGS.  Caption headings in this Agreement and 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 Grantor under this
Agreement shall be joint and several, and all references to Grantor shall mean
each and every Grantor. This means that each of the Borrowers signing below is

NOTICES. All notices required to be given under this Agreement shall be given in
writing, may be sent by facsimile, and shall be effective when actually
delivered if hand delivered or when deposited as certified or registered mail in

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

than one Grantor, notice to any Grantor will constitute notice to all Grantors.
For notice purposes, Grantor agrees to keep Lender informed at all times of
Grantor's current address(es).

POWER OF ATTORNEY.  Grantor hereby appoints Lender as its true and lawful
attorney-in-fact, irrevocably, with full power of substitution to do the
following: (a) to demand, collect, receive, receipt for, sue and recover all
sums of money or other property which may now or hereafter become due, owing or
payable from the Collateral; (b) to execute, sign and endorse any and all
claims, instruments, receipts, checks, drafts or warrants issued in payment for
the Collateral; (c) to settle or compromise any and all claims arising under the
Collateral, and, in the place and stead of Grantor, to execute and deliver its
release and settlement for the claim; and (d) to file any claim or claims or to
take any action or institute or take part in any proceedings, either in its own
name or in the name of Grantor, or otherwise, which in the discretion of Lender
may seem to be necessary or advisable. This power is given as security for the
Indebtedness, and the authority hereby conferred is and shall be irrevocable and
shall remain in full force and effect until renounced by Lender.

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
person or circumstances.  If feasible, any such offending provision shall be
deemed to be modified to be within the limits of enforceability or validity;

the Collateral, this Agreement shall be binding upon and inure to the benefit of
the parties, their successors and assigns.

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 Grantor, shall constitute

                                  (Continued)

a waiver of any of Lender's rights or of any of Grantor's obligations as to any
future transactions. Whenever the consent of the Lender is required under this
Agreement, the granting of such consent by Lender in any instance shall not
constitute continuing consent to subsequent instances where such consent is

                      overruns have occurred.
</TABLE>


METHOD OF DETERMINING AWARD FEE

     The Award Fee will be determined as follows:

     Weight of factor multiplied by the point score for adjective rating
     received for each factor/subfactor = AF earned per factor

     The total AF earned per factor/subfactor will then be applied to the AF
     pool for the rating period to determine the total amount of the AF payable.

VI. METHOD FOR DETERMINING AWARD FEE

     The following is a summary of the principal action involved in determining
the award fee for each evaluation period:

1. Within 10 days following the completion of an evaluation period, the
Performance Evaluation Board shall meet and assess the contractor's overall
performance.

2. The Board shall summarize their findings in the form of a Performance
Evaluation Report and submit it to the Fee determination Official within 15 days
following the completion of the evaluation period.

3. The FDO shall consider the Performance Evaluation Report and discuss it with
the Performance Evaluation Board, if necessary, within 20 days following the
completion of the evaluation period.

4. The FDO shall forward an Award Fee Determination to the Contracting Officer
within 25 days following the completion of the evaluation period. The
Contracting Officer will issue a contract modification reflecting the amount of
award fee earned by the contractor within 30 days following the evaluation
period.

1.0  Introduction

     1.1  Introduction

     This task order establishes and defines the requirements for development of
     a FORTEZZA enhancement for a smartcard that incorporates both Government
     and commercial algorithms along with sufficient storage for certificates
     supporting both hierarchies and features for use with either the Government
     or commercial infrastructure(s). To date, many smartcards are being
     produced by a variety of vendors, but none have the storage capacity or
     performance required to easily operate using both Government and commercial
     algorithm suites. All are limited by the relatively slow operation of the
     ISO 7816 interface. Until a final name has been selected, this smartcard
     shall be referred to as the Forte' Smartcard.

     In addition to standard smartcard capabilities, the Forte' shall
     incorporate a dual interface feature in such a way as to operate as one
     would normally expect in a standard ISO 7816 compliant reader, while
     providing an enhanced mode for a Universal Serial Bus (USB) capable reader
     to transfer data to and from the smartcard at speeds much higher than now
     possible with the ISO 7816 interface. The smartcard processor shall also
     have an integral serial EEPROM interface so that a non-standard multi-chip
     smartcard can be developed at a future time.

     Likely the first of it's kind, this combination of storage space,
     performance, and fast interface will result in a true cryptographic
     processor smartcard. This is a substantial improvement over any card
     currently on the market. Present smartcards act as nothing more than fancy
     stored value cards that can perform public key and signature operations
     relatively faster than possible with software only operation, but they do
     little to provide security for the bulk symmetric encryption functions.
     They rely on software running on the untrusted host workstation to provide
     these services.

     The present FORTEZZA PC card provides a level of physical protection for
     storage of credentials as well as the bulk encryption operation. Analysis
     from the system perspective shows that this is highly desirable even when
     taking into consideration the limitations of operating on an untrusted host
     workstation. The Forte' Smartcard will provide the benefits of a low cost
     form factor while approaching the level of physical integrity of a PC card.
     The low cost and user acceptance of the smartcard form factor for secure
     credential storage in conjunction with the crypto processing provided by
     this smartcard will provide an ideal solution for the customer. Limitations
     as a result of mechanical flexibility and operating environment of the
     smartcard may hinder the ultimate physical security that can be achieved
     using membranes or other forms of active security barriers such as used
     with higher security PC cards, however, this may provide an interesting
     area for research beyond the scope of this effort.

1.2  Terminology and Language

Within this task order, the terms "shall", "is required to", "must", and other
imperative language obligates the contractor.  The term "may", in association
with actions of either the Government or the contractor, means those actions are
optional.

1.3  Prior Versions of the SOW

Version 1.2 of this Statement of Work, dated 23 February 1998, made many
references to the Hurricane smartcard processor being developed by VLSI
Technology in partnership with the Government.  For various reasons, both the
Government and VLSI Technology have agreed that this is no longer in the
interest of either party and have discontinued all work on the design.  It is
anticipated that many other vendors can meet or exceed the requirements for an
acceptable replacement engine.  Moreover, the Government recognizes that it
would be preferable for the smartcard developer to be the primary responsible
party for the development of the engine.

Development of the smartcard engine shall be incorporated in this effort and
shall be the responsibility of the contractor.  Details of the Hurricane design
that the Government considers critical have been added to this SOW and the
contractor should pay particular attention to these requirements as they are
recent additions.

In the event there is a conflict or omission in this or any other document,
whether part of the contract, this SOW, or part of a preliminary or informal
discussion, the contractor shall immediately identify the conflict or omission
to the Contracting Officer, in the form of a written communication, for
resolution by the Government Program Office.

1.4  Background

In an effort to expand the options available to FORTEZZA customers such as the
Defense Messaging System (DMS) the Government has opted to pursue development of
complementary FORTEZZA enabled products including software only versions and
smartcard enabled versions which incorporate most if not all of the FORTEZZA
functions.

In addition to and in parallel with the expansion of FORTEZZA products, the
Government recognizes that the future of cryptographic support will be based
wherever possible on commercially available off the shelf security enabled
applications.  To that end, the Government is adding support for commercial
algorithms to FORTEZZA enabled products in anticipation of the need to bridge
the gap between full Government and full commercial operation.  This is the
primary reason for development of security products such as this FORTEZZA with
Commercial Smartcard.

1.5  Special Provision

Successful operation of this smartcard will depend on a supporting library.  The
supporting library shall be developed in conjunction with the smartcard but no
portion of a software only library, a "Software FORTEZZA", shall be developed or

3.0  Technical Requirements

3.1  General Requirements

The contractor shall provide an Advanced Fortezza with Commercial Smartcard, the
Forte' Smartcard, including all necessary libraries and utilities to be used in
place of a Fortezza PCMCIA card, as used by current applications, providing that
an appropriate smartcard reader is used.  This task is for the purpose of
producing a limited quantity of prototype of proof-of-concept units.  Upon
successful completion the Government may decide to pursue purchase of production
quantities using another contract vehicle.

3.2  FORTEZZA Compliance

provide all of the functionality required to support the FORTEZZA ICD.  Where
the smartcard cannot meet the requirements of the ICD, the contractor shall
immediately identify all variances in writing.

The contractor shall be required to pass applicable Government FORTEZZA
certification tests. Exceptions will be made for issues related to the
performance and storage space of the smartcard. Final Government approval of the
smartcard prototype design shall be required prior to final acceptance of the
prototypes.

3.3  ISO Compliance

The contractor shall comply with applicable requirements of the ISO 7816
smartcard (Identification Card) specifications and standards. Should the
contractor not be able to meet any of the requirements contained therein, the
contractor shall immediately notify the Contracting Officer of any and all
deviations, and shall not proceed until a waiver or other resolution has been
approved by the Government.

3.4  Smartcard Engine Requirements

The following requirements shall be met by the contractor by subcontracting with
an ASIC vendor. The contractor shall work with the Government to develop the
final smartcard engine architecture but the following architectural blocks shall
be considered essential unless otherwise agreed upon in writing.  The contractor
shall submit an architecture and design specification to the Government prior to
engaging in any development with the subcontractor.

The Government recognizes that there are significant limitations with respect to
the die size of the engine.  The goal shall be for the die size to be limited to
25mm/2/.  The Government anticipates that this goal can be met with all of the
specified blocks in the target technology of a 0.5 micron CMOS process.  In any
event, the Government and the contractor shall reach agreement on the final
architecture of the design before the final smartcard engine specification is
finalized.  The contractor shall also investigate all options for using a
standard size die as well as a larger than standard die size with appropriate
stabilization or stiffener support on the smartcard before making a final
recommendation.

     3.4.1  ISO 7816-3 Interface

     The Forte' Smartcard Engine (FSE) shall have a standard ISO 7816 interface.
     The only deviation shall be for an additional mode for fast interface
     operation.  The USB interface shall reuse contacts in a way that does not
     interfere with ISO 7816 operation.  The contractor shall be responsible for
     ensuring that dual functionality exists with neither affecting the other
     and where the interface is automatically and safely selected.

     3.4.2  USB Interface

     The contractor shall be required to incorporate a Universal Serial Bus
     (USB) interface.  The same restrictions with respect to interoperability,
     standard compliance, and automatic configuration shall apply.

     3.4.3  Serial EEPROM Interface

     The contractor shall include a Serial EEPROM interface.  The interface
     shall be able to detect the external memory or otherwise be able to be
     manually configured for operation. The interface shall support a minimum of
     address space for 1MByte of memory.

     The serial EEPROM interface shall not preclude encryption/decryption of
     information in the external EEPROM device under control of the on-board
     RISC processor, or the RISC processor and a hardware encryption engine.

     3.4.4  32 bit RISC Processor

     The contractor shall select a chip vendor that can provide a 32 bit RISC
     processor core.

     3.4.5  Encryption/Decryption Engines

     The contractor shall study the possibility of incorporating both encryption
     algorithms in hardware.  The contractor shall make a recommendation based
     on an analysis of the anticipated use of the card for these operations and
     determine if full hardware support, partial hardware support, or software
     only operation will suffice.

          existing Government documentation and the soon to be released NIST
          standard for Skipjack.

     3.4.6  Non-Deterministic Randomizer

     The hardware randomizer is one of the most critical elements of the
     smartcard engine.  The contractor shall seek design guidance from the
     Government and shall incorporate a hardware randomizer that meets following
     requirements as a minimum:

     The randomizer design shall incorporate at least nine (9) oscillator rings.

     The clock or operating rate of each ring shall not be same as or a multiple
     of any other ring.

     None of the rings shall operate at or near the sample clock rate for the
     randomizer.

     The contractor shall ensure that the physical layout of the randomizer
     prevents inadvertent synchronization of the rings.

     The contractor shall be required to meet Government certification of the
     randomizer output. The Government shall provide an example design to the
     contractor if requested.

     3.4.7  Exponentiator/Multiplier

     The contractor shall incorporate an exponentiator or basic multiplier block
     into the design. This block shall enable math processing performance in
     excess of the current Government smartcard.  The block shall be designed so
     that it does not place an arbitrary limit on the size of the base or
     exponent in an exponentiation operation.  The size shall only be limited by
     the amount of memory available for storage of interim and final results.
     The contractor shall be required to perform operations using a maximum of
     2K base and a 1024 bit exponent.

     3.4.8  Hardware Security and Anti-Tamper Features

     applications in accordance with FORTEZZA ICD.

3.6  Infrastructure Support

     3.6.1  Fortezza Interoperability

     The contractor shall propose a method of "keying" or adding certificates to
     the Forte' Smartcard that is consistent and compatible with the existing
     FORTEZZA infrastructure. The contractor shall identify a specific means for
     both importing and exporting certificates and keys with the Forte'
     Smartcard.

     The contractor may propose a commercial method of providing this support
     but it must be interoperable and able to function as a subordinate in
     an/the existing hierarchy based on the NSM CAW.  The proposal also must
     include details of the physical and logical interfaces to the smartcard.

     The contractor shall submit an infrastructure support plan for the Forte'
     Smartcard.

     The contractor shall prepare all infrastructure documentation such that it
     can be used as a standard or benchmark for future crypto smartcard vendors
     to follow.  The plan shall allow for other implementations and shall not
     require any specific support from the architecture or design of this
     particular smartcard.  The contractor shall propose an infrastructure
     support plan and shall work with the Government to coordinate with any
     ongoing smartcard standards in development, and shall be required to attain
     Government approval prior to delivery of prototype units.

     3.6.2  Certificate Storage

     The Forte' Smartcard shall be capable of holding a minimum of five (5)
     Version 3 X.509 certificates on board including the root certificate.
     Version 3 certificate sizes are variable, however, the contractor shall
     base storage estimates on a presumed maximum of 2048 bytes per certificate.

     The Forte' Smartcard shall be capable of storing a minimum of 3 RSA based
     certificates.

     The contractor shall be required to provide the above certificate storage
     space concurrently and shall not require reprogramming or off-card caching
     to take place in order to support the above requirements.

3.7  Security Mechanisms

The following security mechanisms are identified as critical functions and shall
be firm requirements of the development:

     3.7.1  PIN Protection

     The contractor shall ensure that proper security checks and zeroization
     mechanisms are used on the card Personal Identification Number (PIN) to
     prevent exhaustion attacks.

     The contractor shall provide a flexible and configurable mechanism in
     conjunction with the proposed infrastructure support to allow for use of a
     "memphrase" in place of a PIN should the user's infrastructure support this
     operation.  The contractor shall seek Government guidance with respect to
     this requirement.

     The contractor's design shall not preclude the memphrase from being
     populated with information from a biometric input device.

     3.7.2  Software Authentication

     The contractor shall propose a method of applying a signature to the
     supporting library software which the smartcard will verify upon initial
     invocation.  The contractor shall identify options and alternatives for
     providing this functionality.  Run-time checks past the point of invocation
     are not required.

     3.7.3  Randomizer

     The contractor shall use an on-chip hardware randomizer.  At no time is it
     acceptable for randomization to be dependent on host platform interaction
     or support.  The contractor shall ensure that the randomization performed
     on the smartcard is acceptable to the Government. Documentation and test
     data shall be provided to assure that the randomizer is non-deterministic
     and that it will operate in this manner in all expected operating
     conditions. The contractor shall identify in writing any special
     conditions, possible failure modes, or on-board firmware support required
     to achieve proper random operation.

     The contractor shall obtain Government approval of the randomizer operation
     prior to acceptance of prototype units.

     3.7.4  Key Wrapping

     The contractor shall provide the ability to wrap and export keys consistent
     with existing processes supported by the Fortezza PC card.

     3.7.5  NIST Certification

     The contractor shall obtain National Institute of Standards and Technology
     (NIST) Federal Information Processing Standards (FIPS) certification prior
     to delivery of production units. The certification shall be at a minimum of
     FIPS 140-1/Level 1.

3.8  Smartcard Engine Firmware Development

     The contractor shall be responsible for developing the processor level code
     for the smartcard engine.  This may include but not be limited to base
     level functions such as math and memory management routines and would
     typically be contained in masked ROM.

     The contractor shall author appropriate tests to ensure that the engine
     that is delivered meets all performance and security specifications and
     that the resident firmware is free of errors.

3.9  Smartcard Firmware Development

     The contractor shall develop all firmware that is resident on the smartcard
     including any code that is not permanently contained in the smartcard
     engine.  This code shall control operation of the smartcard in conjunction
     with the library and may contain features to support plug and play
     operation and configuration.

     The contractor shall include all necessary code to allow the smartcard to
     work in conjunction with the library, driver, and reader, such that
     automatic configuration of the smartcard interface can be accomplished.

3.10 Library Support

     3.10.1    Minimum Operation

     The contractor shall provide a supporting library which enables the Forte'
     Smartcard.  The library shall also be compatible with the PCMCIA FORTEZZA
     in such a way that if a smartcard is not present, the library can be used
     to access a FORTEZZA PC card.  The library shall be able to support a
     minimum of operation on Windows 95 and Windows NT 4.0 operating systems and
     shall support the MACI extensions.

     The library shall be capable of performing supporting operations in both
     the advanced interface and ISO 7816 modes of operation.

     3.10.2    Smartcard/Library Interaction

     The contractor shall specify and document all handshaking that occurs
     between the library and the smartcard such as that required for
     configuration or plug and play operation.  This specification shall be
     freely distributable.

3.11 Driver Support

The contractor shall provide a driver to enable operation of the Forte'
Smartcard in conjunction with the supporting library.  This driver, or a
combination of drivers, shall be capable of operation with a range of standard
ISO 7816 smartcard readers.  The driver(s) shall also be capable of operating
with an advanced USB smartcard reader that the contractor anticipates
developing.

It is highly desirable that the drivers be combined into the same unit of code
in a way that the driver, or driver in combination with the reader and/or
library, recognizes the reader resources that are available and automatically
configures for the highest performance operation.  This type of operation has
implications for the level of security that the user can rely upon and it may be
appropriate for some sort of interaction with the user's application to provide
an indication of the level of support provided.  There is no firm requirement
for this sort of interaction and the contractor shall work with the Government
to identify possible options for enabling this functionality.

In the absence of the above configurability, the contractor shall be required to
deliver separate drivers to be configured by the user at the time of
installation.

3.12 Firmware Functionality Waivers

The following functions which are typically implemented in firmware have been
recently put forward as waivers to the standard FORTEZZA requirements.  The
contractor shall seek further guidance and documentation from the Government.

     3.12.1    Firmware Update Command

     The Firmware Update Command shall be designed such that a user logged on to
     the Forte' Smartcard in USER mode will be authorized to update the firmware
     with a new firmware version containing a valid card manufacturer's
     signature.

     3.12.2    InstallX Command

     The InstallX command shall operate consistent with the description in the
     cited document.

     3.12.3    CFB8/CFB16 Modes

     The modem support modes shall operate consistent with the description in
     the cited document.

3.13 Testing

The Forte' Smartcard shall be required to pass all applicable library and
certification tests frequently referred to as the CSC test suite for FORTEZZA
functionality.  Because of the difference between a full PCMCIA and smartcard
implementation, discrepancies will exist and must be brought to the attention of
the Government in form of written communication from the contractor.

The contractor shall develop and propose a means for fully testing the
smartcard's capabilities, including the commercial algorithms.  Testing the
Forte' Smartcard with security enabled commercial applications as a primary
means of testing is acceptable.  The contractor shall author and deliver an
overall test plan.

The contractor shall be required to perform all testing identified above, and
must attain written Government approval, prior to final acceptance of the
prototypes.

     3.13.1    Prototype Units

     The contractor shall deliver ten (10) alpha prototype units to the
     Government.  These prototype units should be designed so that extensive
     functional and security tests may be performed on them.  The prototypes
     shall be constructed using standard commercial practices and design
     techniques commonly referred to as a "breakout board".  The contractor
     shall submit a proposal for their design to the Government for approval.

     The contractor shall deliver an additional one hundred (100) beta prototype
     units constructed as standard smartcards.

     3.13.2    Smartcard Readers

     The contractor shall be required to deliver one hundred (100) USB enabled
     smartcard readers.  The readers shall be able to access the USB interface
     on the Forte' smartcard and shall have a high-speed interface to the host
     which may also be USB compliant.

     3.13.3    Demonstration of Fortezza Interoperability

     The contractor shall demonstrate interoperability between all possible
     pairings of the latest released version of the following:

               combination with the advanced USB reader, performing all
               applicable Fortezza functions.

               3.13.5.2  Serial EEPROM Interface

               The contractor shall show operation of the serial EEPROM
               interface by incorporation with one or more alpha prototype
               units. The contractor shall show that the smartcard engine, in
               combination with on-board firmware, is capable of accessing a
               standard serial EEPROM device. The EEPROM device shall contain
               1MByte or more of memory.

4.0  Documentation

The contractor shall provide an interface description (ICD), an application
implementors guide (AIG), and the equivalent of a CI programmer's guide (CIPG),
describing the smartcard interface and operations.  All documentation shall be
created using best commercial practices and it may be based upon current
Fortezza documentation.  These shall be freely distributable.

The contractor shall provide as required, detailed design information necessary
for the Government to perform a security analysis of the card implementation.
Detailed design information shall include all information such as electronic
schematics and software source code.  This information will be handled as
proprietary and used for evaluation purposes only.

                    Task Order for an Advanced Fortezza and
                        Commercial Algorithm Smartcard



                                  Version 2.3
                                6 October 1998

1.0  Introduction

     1.1  Introduction

     This task order establishes and defines the requirements for development of
     a FORTEZZA enhancement for a smartcard that incorporates both Government
     and commercial algorithms along with sufficient storage for certificates
     supporting both hierarchies and features for use with either the Government
     or commercial infrastructure(s). To date, many smartcards are being
     produced by a variety of vendors, but none have the storage capacity or
     performance required to easily operate using both Government and commercial
     algorithm suites. All are limited by the relatively slow operation of the
     ISO 7816 interface. Until a final name has been selected, this smartcard
     shall be referred to as the Forte' Smartcard.

     In addition to standard smartcard capabilities, the Forte' shall
     incorporate a dual interface feature in such a way as to operate as one
     would normally expect in a standard ISO 7816 compliant reader, while
     providing an enhanced mode for a Universal Serial Bus (USB) capable reader
     to transfer data to and from the smartcard at speeds much higher than now
     possible with the ISO 7816 interface. The smartcard processor shall also
     have an integral serial EEPROM interface so that a non-standard multi-chip
     smartcard can be developed at a future time.

     Likely the first of it's kind, this combination of storage space,
     performance, and fast interface will result in a true cryptographic
     processor smartcard. This is a substantial improvement over any card
     currently on the market. Present smartcards act as nothing more than fancy
     stored value cards that can perform public key and signature operations
     relatively faster than possible with software only operation, but they do
     little to provide security for the bulk symmetric encryption functions.
     They rely on software running on the untrusted host workstation to provide
     these services.

     The present FORTEZZA PC card provides a level of physical protection for
     storage of credentials as well as the bulk encryption operation. Analysis
     from the system perspective shows that this is highly desirable even when
     taking into consideration the limitations of operating on an untrusted host
     workstation. The Forte' Smartcard will provide the benefits of a low cost
     form factor while approaching the level of physical integrity of a PC card.
     The low cost and user acceptance of the smartcard form factor for secure
     credential storage in conjunction with the crypto processing provided by
     this smartcard will provide an ideal solution for the customer. Limitations
     as a result of mechanical flexibility and operating environment of the
     smartcard may hinder the ultimate physical security that can be achieved
     using membranes or other forms of active security barriers such as used
     with higher security PC cards, however, this may provide an interesting
     area for research beyond the scope of this effort.

1.2  Terminology and Language

Within this task order, the terms "shall", "is required to", "must", and other
imperative language obligates the contractor.  The term "may", in association
with actions of either the Government or the contractor, means those actions are
optional.

1.3  Prior Versions of the SOW

Version 1.2 of this Statement of Work, dated 23 February 1998, made many
references to the Hurricane smartcard processor being developed by VLSI
Technology in partnership with the Government.  For various reasons, both the
Government and VLSI Technology have agreed that this is no longer in the
interest of either party and have discontinued all work on the design.  It is
anticipated that many other vendors can meet or exceed the requirements for an
acceptable replacement engine.  Moreover, the Government recognizes that it
would be preferable for the smartcard developer to be the primary responsible
party for the development of the engine.

Development of the smartcard engine shall be incorporated in this effort and
shall be the responsibility of the contractor.  Details of the Hurricane design
that the Government considers critical have been added to this SOW and the
contractor should pay particular attention to these requirements as they are
recent additions.

In the event there is a conflict or omission in this or any other document,
whether part of the contract, this SOW, or part of a preliminary or informal
discussion, the contractor shall immediately identify the conflict or omission
to the Contracting Officer, in the form of a written communication, for
resolution by the Government Program Office.

1.4  Background

In an effort to expand the options available to FORTEZZA customers such as the
Defense Messaging System (DMS) the Government has opted to pursue development of
complementary FORTEZZA enabled products including software only versions and
smartcard enabled versions which incorporate most if not all of the FORTEZZA
functions.

In addition to and in parallel with the expansion of FORTEZZA products, the
Government recognizes that the future of cryptographic support will be based
wherever possible on commercially available off the shelf security enabled
applications.  To that end, the Government is adding support for commercial
algorithms to FORTEZZA enabled products in anticipation of the need to bridge
the gap between full Government and full commercial operation.  This is the
primary reason for development of security products such as this FORTEZZA with
Commercial Smartcard.

     1.5  Special Provision

     Successful operation of this smartcard will depend on a supporting library.
     The supporting library shall be developed in conjunction with the smartcard
     but no portion of a software only library, a "Software FORTEZZA", shall be
     developed or funded under this contracted effort.

3.0  Technical Requirements

     3.1  General Requirements

     The contractor shall provide an Advanced Fortezza with Commercial
     Smartcard, the Forte' Smartcard, including all necessary libraries and
     utilities to be used in place of a Fortezza PCMCIA card, as used by current
     applications, providing that an appropriate smartcard reader is used. This
     task is for the purpose of producing a limited quantity of prototype of
     proof-of-concept units. Upon successful completion the Government may
     decide to pursue purchase of production quantities using another contract
     vehicle.

     3.2  FORTEZZA Compliance

     Reference the Fortezza ICD. The Forte' Smartcard and supporting library
     shall provide all of the functionality required to support the FORTEZZA
     ICD. Where the smartcard cannot meet the requirements of the ICD, the
     contractor shall immediately identify all variances in writing.

     The contractor shall be required to pass applicable Government FORTEZZA
     certification tests. Exceptions will be made for issues related to the
     performance and storage space of the smartcard. Final Government approval
     of the smartcard prototype design shall be required prior to final
     acceptance of the prototypes.

     3.3  ISO Compliance

     The contractor shall comply with applicable requirements of the ISO 7816
     smartcard (Identification Card) specifications and standards. Should the
     contractor not be able to meet any of the requirements contained therein,
     the contractor shall immediately notify the Contracting Officer of any and
     all deviations, and shall not proceed until a waiver or other resolution
     has been approved by the Government.

     3.4  Smartcard Engine Requirements

     The following requirements shall be met by the contractor by subcontracting
     with an ASIC vendor. The contractor shall work with the Government to
     develop the final smartcard engine architecture but the following
     architectural blocks shall be considered essential unless otherwise agreed
     upon in writing. The contractor shall submit an architecture and design
     specification to the Government prior to engaging in any development with
     the subcontractor.

                            FOR OFFICIAL USE ONLY                  Page 5 of 17
<PAGE>

The Government recognizes that there are significant limitations with respect to
the die size of the engine.  The goal shall be for the die size to be limited to
25mm/2/.  The Government anticipates that this goal can be met with all of the
specified blocks in the target technology of a 0.5 micron CMOS process.  In any
event, the Government and the contractor shall reach agreement on the final
architecture of the design before the final smartcard engine specification is
finalized.  The contractor shall also investigate all options for using a
standard size die as well as a larger than standard die size with appropriate
stabilization or stiffener support on the smartcard before making a final
recommendation.

     3.4.1  ISO 7816-3 Interface

     The Forte' Smartcard Engine (FSE) shall have a standard ISO 7816 interface.
     The only deviation shall be for an additional mode for fast interface
     operation.  The USB interface shall reuse contacts in a way that does not
     interfere with ISO 7816 operation.  The contractor shall be responsible for
     ensuring that dual functionality exists with neither affecting the other
     and where the interface is automatically and safely selected.

     3.4.2  USB Interface

     The contractor shall be required to incorporate a Universal Serial Bus
     (USB) interface.  The same restrictions with respect to interoperability,
     standard compliance, and automatic configuration shall apply.

     3.4.3  Serial EEPROM Interface

     The contractor shall include a Serial EEPROM interface.  The interface
     shall be able to detect the external memory or otherwise be able to be
     manually configured for operation. The interface shall support a minimum of
     address space for 1MByte of memory.

     The serial EEPROM interface shall not preclude encryption/decryption of
     information in the external EEPROM device under control of the on-board
     RISC processor, or the RISC processor and a hardware encryption engine.

     3.4.4  32 bit RISC Processor

     The contractor shall select a chip vendor that can provide a 32 bit RISC
     processor core.

     3.4.5  Encryption/Decryption Engines

     The contractor shall study the possibility of incorporating both encryption
     algorithms in hardware.  The contractor shall make a recommendation based
     on an analysis of the anticipated use of the card for these operations and
     determine if full hardware support, partial hardware support, or software
     only operation will suffice.

            3.4.5.1   DES Engine

            The contractor shall use a DES engine that complies with the NIST
            certified specification.


            3.4.5.2  Skipjack Engine

            The contractor shall implement the Skipjack engine in compliance
            with existing Government documentation and the soon to be released
            NIST standard for Skipjack.

     3.4.6  Non-Deterministic Randomizer

     The hardware randomizer is one of the most critical elements of the
     smartcard engine.  The contractor shall seek design guidance from the
     Government and shall incorporate a hardware randomizer that meets following
     requirements as a minimum:

     The randomizer design shall incorporate at least nine (9) oscillator rings.

     The clock or operating rate of each ring shall not be same as or a multiple
     of any other ring.

     None of the rings shall operate at or near the sample clock rate for the
     randomizer.

     The contractor shall ensure that the physical layout of the randomizer
     prevents inadvertent synchronization of the rings.

     The contractor shall be required to meet Government certification of the
     randomizer output. The Government shall provide an example design to the
     contractor if requested.

     3.4.7  Exponentiator/Multiplier

     The contractor shall incorporate an exponentiator or basic multiplier block
     into the design. This block shall enable math processing performance in
     excess of the current Government smartcard.  The block shall be designed so
     that it does not place an arbitrary limit on the size of the base or
     exponent in an exponentiation operation.  The size shall only be limited by
     the amount of memory available for storage of interim and final results.
     The contractor shall be required to perform operations using a maximum of
     2K base and a 1024 bit exponent.

     3.4.8  Hardware Security and Anti-Tamper Features

     The contractor shall research the available security features that can be
     added to the engine. Several features routinely included in common
     smartcards include, under and over voltage

     performed in hardware.

     3.4.13    Test Mode Bypasses

     The contractor shall identify any "undocumented" or test mode functions
     used for debugging.  The contractor shall submit a report documenting such
     functions.  The contractor shall be responsible for ensuring that an
     acceptable lock-out mechanism be put in place so that these modes cannot be
     tampered with beyond the prototype period.

3.5  Required Algorithms

The algorithms to be supported are the same as those which are required for
FORTEZZA(R) compliance.  Reference the applicable documents in Section 2.0.

     3.5.1     Distribution of Processing

     The following algorothims and functions shall be incorporated and/or
     performed primarily by hardware and firmware entirely resident on the
     smartcard when access to the smartcard is through use of a fast USB
     smartcard reader.  The contractor shall include hardware macro blocks into
     the smartcard engine design to support the following provided that the
     engine die size can be restricted to the ISO 7816 limits.  The contractor

3.6  Infrastructure Support

     3.6.1  Fortezza Interoperability

     The contractor shall propose a method of "keying" or adding certificates to
     the Forte' Smartcard that is consistent and compatible with the existing
     FORTEZZA infrastructure. The contractor shall identify a specific means for
     both importing and exporting certificates and keys with the Forte'
     Smartcard.

     The contractor may propose a commercial method of providing this support
     but it must be interoperable and able to function as a subordinate in
     an/the existing hierarchy based on the NSM CAW.  The proposal also must
     include details of the physical and logical interfaces to the smartcard.

     The contractor shall submit an infrastructure support plan for the Forte'
     Smartcard.

     The contractor shall prepare all infrastructure documentation such that it
     can be used as a standard or benchmark for future crypto smartcard vendors
     to follow.  The plan shall allow for other implementations and shall not
     require any specific support from the architecture or design of this
     particular smartcard.  The contractor shall propose an infrastructure
     support plan and shall work with the Government to coordinate with any
     ongoing smartcard standards in development, and shall be required to attain

     base storage estimates on a presumed maximum of 2048 bytes per certificate.

     The Forte' Smartcard shall be capable of storing a minimum of 3 RSA based
     certificates.

     The contractor shall be required to provide the above certificate storage
     space concurrently and shall not require reprogramming or off-card caching
     to take place in order to support the above requirements.

     3.7.1  PIN Protection

     The contractor shall ensure that proper security checks and zeroization
     mechanisms are used on the card Personal Identification Number (PIN) to
     prevent exhaustion attacks.

     The contractor shall provide a flexible and configurable mechanism in
     conjunction with the proposed infrastructure support to allow for use of a
     "memphrase" in place of a PIN should the user's infrastructure support this
     operation.  The contractor shall seek Government guidance with respect to
     this requirement.

     The contractor's design shall not preclude the memphrase from being
     populated with information from a biometric input device.

     3.7.2  Software Authentication

     The contractor shall propose a method of applying a signature to the
     supporting library software which the smartcard will verify upon initial
     invocation.  The contractor shall identify options and alternatives for
     providing this functionality.  Run-time checks past the point of invocation
     are not required.

     3.7.3  Randomizer

     The contractor shall use an on-chip hardware randomizer.  At no time is it
     acceptable for randomization to be dependent on host platform interaction
     or support.  The contractor shall ensure that the randomization performed
     on the smartcard is acceptable to the Government. Documentation and test
     data shall be provided to assure that the randomizer is non-deterministic
     and that it will operate in this manner in all expected operating
     conditions. The contractor shall identify in writing any special
     conditions, possible failure modes, or on-board firmware support required
     to achieve proper random operation.

     The contractor shall obtain Government approval of the randomizer operation
     prior to acceptance of prototype units.

     3.7.4  Key Wrapping

     The contractor shall provide the ability to wrap and export keys consistent
     with existing processes supported by the Fortezza PC card.

     3.7.5  NIST Certification

     The contractor shall obtain National Institute of Standards and Technology
     (NIST) Federal Information Processing Standards (FIPS) certification prior
     to delivery of production units. The certification shall be at a minimum of
     FIPS 140-1/Level 1.

3.8  Smartcard Engine Firmware Development

     The contractor shall be responsible for developing the processor level code
     for the smartcard engine.  This may include but not be limited to base
     level functions such as math and memory management routines and would
     typically be contained in masked ROM.

     The contractor shall author appropriate tests to ensure that the engine
     that is delivered meets all performance and security specifications and
     that the resident firmware is free of errors.

3.9  Smartcard Firmware Development

     The contractor shall develop all firmware that is resident on the smartcard
     including any code that is not permanently contained in the smartcard
     engine.  This code shall control operation of the smartcard in conjunction
     with the library and may contain features to support plug and play
     operation and configuration.

     The contractor shall include all necessary code to allow the smartcard to
     work in conjunction with the library, driver, and reader, such that
     automatic configuration of the smartcard interface can be accomplished.

3.10 Library Support

     3.10.1    Minimum Operation

     The contractor shall provide a supporting library which enables the Forte'
     Smartcard.  The library shall also be compatible with the PCMCIA FORTEZZA
     in such a way that if a smartcard is not present, the library can be used
     to access a FORTEZZA PC card.  The library shall be able to support a
     minimum of operation on Windows 95 and Windows NT 4.0 operating systems and
     shall support the MACI extensions.

     The library shall be capable of performing supporting operations in both
     the advanced interface and ISO 7816 modes of operation.

                            FOR OFFICIAL USE ONLY                  Page 12 of 17

 
<PAGE>

     3.10.2    Smartcard/Library Interaction

     The contractor shall specify and document all handshaking that occurs
     between the library and the smartcard such as that required for
     configuration or plug and play operation.  This specification shall be
     freely distributable.

3.11 Driver Support

The contractor shall provide a driver to enable operation of the Forte'
Smartcard in conjunction with the supporting library.  This driver, or a
combination of drivers, shall be capable of operation with a range of standard
ISO 7816 smartcard readers.  The driver(s) shall also be capable of operating
with an advanced USB smartcard reader that the contractor anticipates
developing.

It is highly desirable that the drivers be combined into the same unit of code
in a way that the driver, or driver in combination with the reader and/or
library, recognizes the reader resources that are available and automatically
configures for the highest performance operation.  This type of operation has
implications for the level of security that the user can rely upon and it may be
appropriate for some sort of interaction with the user's application to provide
an indication of the level of support provided.  There is no firm requirement
for this sort of interaction and the contractor shall work with the Government
to identify possible options for enabling this functionality.

In the absence of the above configurability, the contractor shall be required to
deliver separate drivers to be configured by the user at the time of
installation.

3.12 Firmware Functionality Waivers

The following functions which are typically implemented in firmware have been
recently put forward as waivers to the standard FORTEZZA requirements.  The
contractor shall seek further guidance and documentation from the Government.

     3.12.1    Firmware Update Command

     The Firmware Update Command shall be designed such that a user logged on to
     the Forte' Smartcard in USER mode will be authorized to update the firmware
     with a new firmware version containing a valid card manufacturer's
     signature.

     3.12.2    InstallX Command

     The InstallX command shall operate consistent with the description in the
     cited document.

     3.12.3    CFB8/CFB16 Modes

     The modem support modes shall operate consistent with the description in
     the cited document.

3.13 Testing

The Forte' Smartcard shall be required to pass all applicable library and
certification tests frequently referred to as the CSC test suite for FORTEZZA
functionality.  Because of the difference between a full PCMCIA and smartcard
implementation, discrepancies will exist and must be brought to the attention of
the Government in form of written communication from the contractor.

The contractor shall develop and propose a means for fully testing the
smartcard's capabilities, including the commercial algorithms.  Testing the
Forte' Smartcard with security enabled commercial applications as a primary
means of testing is acceptable.  The contractor shall author and deliver an
overall test plan.

The contractor shall be required to perform all testing identified above, and
must attain written Government approval, prior to final acceptance of the
prototypes.

     3.13.1    Prototype Units

     The contractor shall deliver ten (10) alpha prototype units to the
     Government.  These prototype units should be designed so that extensive
     functional and security tests may be performed on them.  The prototypes
     shall be constructed using standard commercial practices and design
     techniques commonly referred to as a "breakout board".  The contractor
     shall submit a proposal for their design to the Government for approval.

     The contractor shall deliver an additional one hundred (100) beta prototype
     units constructed as standard smartcards.

     3.13.2    Smartcard Readers

     The contractor shall be required to deliver one hundred (100) USB enabled
     smartcard readers.  The readers shall be able to access the USB interface
     on the Forte' smartcard and shall have a high-speed interface to the host
     which may also be USB compliant.

     3.13.3    Demonstration of Fortezza Interoperability

     The contractor shall demonstrate interoperability between all possible
     pairings of the latest released version of the following:

<PAGE>

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 immediately assigned to all tasks, and all
               subtasks appear to have been well managed.

       Rating: EXCELLENT

Performance       
       .       System Engineering produced a flexible architecture that was able
               to respond to numerous problems.
                                                                   
       .       Few of the 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 is not perfect, it
               certainly was capable of responding to this particular debugging
               exercise.

       .       Litronic is responsive in addressing support concerns.         
       .       Litronic communicates problems and concerns very well with the 
               Program Office.                                                 

       Rating: EXCELLENT

Schedule:
       .       The contractor had some difficulty in meeting the schedule for CI
               Library 1.52b.

       Rating: GOOD

COST
       .       Litronic effectively controlled program costs.            
       .       No problems were evident in Litronic's billing procedures. 

       Rating: GOOD

PART 1 - Restate Section H.13 Option to Extend the Term of the Contract

SECTION H - SPECIAL CONTRACT REQUIREMENTS

H.13 52.217-9001 OPTION TO EXTEND THE TERM OF THE CONTRACT (OCT 1993) is
restated as follows to allow greater flexibility in exercising the option:

(a)  The Government may unilaterally extend the term of this contract by written
notice to the Contractor within 60 days following the President's signing of the
annual Appropriations Act or October 1, whichever is later, for each respective
option, provided that the Contracting Officer has given preliminary notice, in
writing, to the Contractor, of the Government's intent to renew, in any portion
and from time to time, at least 60 days prior to the expiration date of the
current period of performance. Such preliminary notice will not be deemed to
commit the Government to renewals. If the Government exercises this right to
renew, the contract, as renewed shall be deemed to include this option clause.
The total duration of this contract, including the exercise of any option to
renew under this clause, shall not exceed 36 months.

(b)  The composition of the total man-hours of direct labor and other direct
costs for each option is as follows:

restated as follows to allow greater flexibility in exercising the option:

(a) The Government may unilaterally extend the term of this contract by written
notice to the Contractor within 60 days following the President's signing of the
annual Appropriations Act or October 1, whichever is later, for each respective
option, provided that the Contracting Officer has given preliminary notice, in
writing, to the Contractor, of the Government's intent to renew, in any portion
and from time to time, at least 60 days prior to the expiration date of the
current period of performance. Such preliminary notice will not be deemed to
commit the Government to renewals. If the Government exercises this right to
renew, the contract, as renewed shall be deemed to include this option

     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

obligated to perform all TTOs issued pursuant to the technical specification
cited in paragraph (b), above. TTOs shall not constitute a basis for any
increase in the fee or extension to the period of performance. Nothing contained

estimated cost or fund limitation set forth in the order.

     (d) All TTOs furnished to the Contractor shall be incorporated into this

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.

   Rating:  GOOD

                     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:

   Telecommunications:  Preparation, transmission, communication, or related
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.

   The contractor or subcontractor shall comply with DoD 5220.22-A, COMSEC Annex
to the National Industrial Security Program Operating Manual, dated June 1995.
<PAGE>
 
   Equipment, devices, techniques and services required for securing or
protecting contractor telecommunications will be acquired only from sources
listed in the NSA Information Systems Security Products and Services Catalog.
Contractors shall comply with the STU-III Doctrine or other appropriate
doctrine.

   Keying materials required for the operation of secured and protected
telecommunications systems will be furnished by the government. A Defense
Courier Service account may be required for shipment of this material.

   The prime contractor shall include requirements that conform with this DD254
in all subcontracts that require secured or protected equipment or services.

   COMSEC incidents will be reported as follows:  The contractor shall make an
immediate telephonic notification to NSA of any incident or violation of COMSEC
requirements. Notification will be made to the Office of COMSEC Insecurities on
(410) 859-6811. Violations or possible compromises of COMSEC information should
also be reported to S41 at (410) 859-6255 or the NSA Support Services Operations
Center, Security Duty Officer at (301) 688-6911. A follow-up written report is
required and shall be appropriately classified. Specific guidance as to proper
classification will be provided by NSA. The report shall be submitted to the
Contracting Officer, ATTN:  V514 and the appropriate Defense Investigative
Service (DIS) Cognizant Security Office. If accountable COMSEC material is
involved, the Central Office of Record will also be provided a copy of the
report.

   Clarification and guidance for COMSEC requirements may be directed to the NSA
Procedural and Material Control Branch at (301) 688-8110.

                                                                  September 1996

                         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).

PERFORMANCE EXCEEDED CONTRACTUAL REQUIREMENTS? (Comment on any factors in PART
II where the Contractor clearly exceeded contractual requirements, i.e.,
acceleration of scheduled deliveries without additional consideration, exceeding
contractual technical specification requirements by the introduction of
new/innovative processes or techniques.  However, if these outstanding
achievements on the part of the Contractor are done as additional work with
additional compensation it then becomes a contractual requirement. The exception
to this would be when the contract is award fee or incentive fee and the
Contractor earns an excellent rating or achieves the maximum incentives
available.  In these instances. you clearly have support for performance
exceeding "TARGET" contractual requirements).

Contractor proactively performed several small investigative efforts to enhance
the technology

RATING
<PAGE>
 
EXCELLENT - The contractor clearly is exceeding or has exceeded the requirements
of the contract in a manner which is of benefit to the Government.  Major
contractual milestones are met and some are ahead of schedule, costs are within
or under the estimated target or cost of the contract and the contractor has
demonstrated a dynamic, positive approach to the administration of the contract.
(Cost language is not applicable to FPP contracts.)

GOOD - The contractor is/has satisfied all major requirements of the contract.
Although some performance elements may need improvement, they are more than
offset by better performance in other more critical areas.  Needed improvements
do not impede ability to meet contract milestones and to satisfy requirements.
Target or estimated cost are withing budget.  (Cost language is not applicable
to FFP contracts.)

MARGINAL - Contractor performance is/was minimally acceptable.  Contract
performance is or has caused schedule delays. technical problems or cost impacts
requiring contractual adjustments.  Interim reports:  contractor has not met
certain performance requirements, but is taking corrective action.

UNACCEPTABLE - Interim reports:  to date the contractor has not met major
contractual requirement.  The present rate of progress indicates major obstacles
to successful fulfillment of contractual requirements.  Final report:  the
contractor experienced obstacles that have precluded meeting major contractual
requirements and have resulted in adverse Government actions  (i.e., termination
for default, descopes, etc.)

OVERALL I WOULD RATE THIS CONTRACTOR FOR THIS PERIOD:  (If "EXCELLENT" is
marked, specific examples must be cited in PART III).

X EXCELLENT    ____ GOOD         ___ MARGINAL     ___ ACCEPTABLE

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

     Certain transactions which occur pursuant to this contract, for example,
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.

     The Contractor shall provide the Contracting Officer with written notice of
any proposed tax assessments, exemptions, exclusions or refunds which could

applicability of the tax, and/or adjust the parties' liability for costs

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
applicable statute, and to resolve the applicability of such with state or local
taxing authorities.

          (6) "Vendor", as used in this clause, means a person or agency that
sells supplies or materials to a Contractor or subcontractor.

          (7) "United States", as used in this clause, means all areas under the
territorial sovereignty of the United States (U.S.) and the Trust Territory of
the Pacific Islands.

     (b) No subcontracts or purchase orders which involve design, manufacture,
production, assembly, inspection, or test in a location not in the U.S., of
COMSEC equipment, components, or parts, which are not covered by a specification
or standard listed in MIL-P-11268, MIL-E-16400, or MIL-E-5400 shall be made
under this contract without the prior written approval of the Contracting
Officer. The Contractor further agrees to include this clause in any or all
subcontracts or purchase orders he may let pursuant to this contract for COMSEC
equipment, components, or parts, except those subcontracts/purchase orders for
which waiver is required (i.e., non-US sources). Under no circumstances will any
custom large scale integrated circuit or likeness thereof be sent outside the
U.S. for any reason.

     (c) Requests for permission to deviate from the requirements of paragraph
(b) will be handled on a case-by-case basis through the Contracting Officer.
Each waiver request must provide a strong and compelling reason why the waiver
should be granted in addition to the benefit the Government would gain by the
granting of a waiver. Furthermore, prior to the approval of any waiver, the
Contractor shall demonstrate to the Government through submission of an
acceptable Anonym  ity Plan (data item Dl-NDTl-80566), that procedures are in
place to ensure that the offshore vendor remains unaware of the relationship
between the prime contractor and the Department of Defense and/or Maryland
Procurement Office (MPO). As a minimum, the following conditions will be imposed
if a waiver is granted:

          (1) Purchase orders and drawings provided to a subcontractor or vendor
outside the United States shall not carry any identification that reveals a
contractor relationship with the Department of Defense and the MPO. This
restriction includes the Contractor's prime contract number with the Government
and 98230/0NXXXXXX parts identification numbers.

          (2) The prime contractor, when required to mark items with the
manufacturer's code 98230 or drawing numbers 0NXXXXXX, shall only mark these
items at a facility located within the U.S. Marking parts with 0N markings and
the 98230 code specifics that the parts are for MPO use only. lf parts marked
with the MPO identification code (including rejects and parts not usable for MPO
programs) are allocated for non-MPO programs or for resale to other customers,
then

markings associated with the MPO identification code must be removed from the
parts before the parts are sent to non-MPO programs or other customers.

     (3) The Government has the right to an equitable adjustment to the contract
price as consideration for granting approval to acquire COMSEC equipment,
components and parts from sources outside the United States (unless the waiver
as granted prior to contract award).

and alternate custodian, and control the material in accordance with procedures
specified in the "COMSEC Supplement to the Industrial Security Manual for
Safeguarding Information" dated April 1975. Existing COMSEC accounts established
as a result of previous or other contracts may be used.

H.12 352.227-9004 YEAR 2000 COMPLIANCE - NON-COMMERCIAL ITEMS (JAN 1997)

Definition:  INFORMATION TECHNOLOGY means any equipment or interconnected system

H.14 Contractor Participation in Contractor Performance Evaluation Assessments

   This contract will be subject to periodic Contractor Performance Evaluation
Assessments. In accordance with FAR 42.1502, the Maryland Procurement Office
maintains a database on Contractor past performance applicable to all contracts
over $500,000. Information on the performance of this contract will be
maintained in the database and updated on a yearly basis (if contract period of
performance exceeds one year) and at the completion of the contract. The
Contractor's participation in this process, in terms of review of the Contractor
Performance Evaluation Assessment form, shall not cause an increase in the
estimated cost/price of this contract. Any costs which are anticipated to be
expended towards participation in this review process should be (have been)
proposed in the initial price of this contract.

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.

1.3 52.232-33 MANDATORY INFORMATION FOR ELECTRONIC FUNDS TRANSFER PAYMENT (AUG
1996)

     (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
payment information by electronic transfer. As used in this clause, the term
"EFT" refers to the funds transfer and may also include the information
transfer.

     (b) Mandatory submission of Contractor's EFT information.
         (1) The Contractor is required, as a condition to any payment under
this contract, to provide the Government with the information required to make
payment by EFT as described in paragraph (d) of this clause, unless the payment
office determines that submission of the information is not required. However,
until January 1, 1999, in the event the Contractor certifies in writing to the
payment office that the Contractor does not have an account with a financial
institution or an authorized payment agent, payment shall be made by other than
EFT. For any payments to be made after January 1, 1999, the Contractor shall
provide EFT information as described in paragraph (d) of this clause.

         (2) If the Contractor provides EFT information applicable to multiple
contracts, the Contractor shall specifically state the applicability of this EFT
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
Government payment office named in this contract. If more than one payment
office is named for the contract, the Contractor shall provide a separate notice
to each office. ln the event that the EFT information changes, the Contractor
shall be responsible for providing the changed information to the designated
payment office(s).

     (d) Required EFT information. The Government may make payment by EFT
through either an Automated Clearing House (ACH) subject to the banking laws of
the United States or the Federal Reserve Wire Transfer System at the
Government's option. The Contractor shall provide
<PAGE>
 
                                                                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) lf 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. lf 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
<PAGE>
 
                                                                MDA904-97-C-0424
                                                                        26 of 34

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.

                                   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".

*Hadson Systems is now LG & E Energy Systems, Inc., a Kentucky Corporation

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

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.

be entitled to recover its costs of suit and reasonable attorney's fees.

Premises and the Building, and the usable area of the Premises as set forth in
such certification. In no event shall any adjustments be made to any such

than two percent (2%) of the actual correct measurement. Upon final
determination of the rentable and usable areas of the Premises and the rentable

     5. ANNUAL BASIC RENT.

          (a) Tenant agrees to pay Landlord as Annual Basic Rent for the
     Premises the Annual Basic Rent ___________ (subject to adjustment as
     hereinafter provided) in twelve (12) equal monthly installments, each in
     advance on the first day of each calendar month during the Term, except
     that one (1) full installment of Monthly Basic Rent at the rate of ________
     per Rentable Square Foot of the Premises shall be paid upon the execution
     of this Lease, with such Monthly Basic Rent to be applied as provided in
     Subparagraph 5(c) below. If the Term of this Lease commences or ends on a
     day other than the first day of a calendar month, then the rent for such
     period shall be prorated in the proportion that the number of days this
     Lease is in effect during such period bears to the actual number of days in
     such calendar month. In addition to the Annual Basic Rent, Tenant agrees to
     pay as additional rent the amount of rent adjustments and other charges
     required by this Lease. All rent shall be paid to Landlord, without prior
     demand and without any deduction or offset (except as otherwise provided in
     Paragraph 64 and Exhibit "G"), in lawful money of the United States of
     America, at the address of ________________________ or to such other person
     or at such other place as Landlord may from time to time designate in
     writing. Further, all charges to be paid by Tenant hereunder, including,
     without limitation, payments for Operating Expenses, insurance, repairs and
     parking, shall be considered additional rent for purposes of this Lease,
     and the word rent" in this Lease shall include such additional rent unless
     the context specifically or clearly implies that only Annual Basic Rent is
     referenced.

          (d) Late Charges. In the event Tenant fails to pay any installment of
     rent when due or in the event Tenant fails to make any other payment for
     which Tenant is obligated under this Lease when due, such late amount shall
     accrue interest and Tenant shall pay Landlord as additional rent such
     interest on such amount at the lesser of the Prime Rate (as defined below)
     plus two (2) percentage points or the maximum rate permitted by law (the
     "Interest Rate") from the date such amount became due until such amount is
     paid. "Prime Rate" shall mean the prime or reference rate announced by Bank
     of America, N.T.&S.A., from time to time, or in the event such institution
     no longer makes commercial loans in Southern California, the then
     prevailing prime or reference rate announced by the three (3) largest banks
     (in terms of assets) in the United States. In addition, on any third (3rd)
     and subsequent occasion during a particular Lease Year which Landlord
     notifies Tenant in writing of a late payment of rent under this Lease,
     Tenant shall pay to Landlord, as additional rent, concurrently with such
     late payment amount, or promptly upon receipt of such third (3rd) or
     subsequent notice, whichever is later, a late charge equal to four percent
     (4%) of the amount due to compensate Landlord for the extra costs incurred
     as a result of such late payment. Unless Landlord notifies Tenant in
     writing, within thirty (30) days following the due date of a payment, that
     Landlord is imposing such late charge, then Landlord shall waive the right
     to impose such late charge. The parties agree that such interest and late
     charge represent a fair and reasonable estimate of the detriment that
     Landlord will suffer by reason of late payment by Tenant. Acceptance of any
     such interest and late charge shall 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.

period in question, including, but not limited to, the following:

<PAGE>
 
    
     road maintenance, refuse removal and for other governmental services
     formerly provided without charge to property owners or occupants. It is the
     intention of Tenant and Landlord that all such new and increased
     assessments, taxes, fees, levies and charges be included within the
     definition of "real property taxes" for the purposes of this Lease;

          (iii)  any assessment, tax, fee, levy or charge allocable to or

     hereunder or pursuant to other leases in the Building, including, without
     limitation, any gross income tax or excise tax levied by the State, city or
     federal government, or any political subdivision thereof, with respect to
     the receipt of such rent, or upon or with respect to the possession,
     leasing, operating, management, maintenance, alteration, repair, use or
     occupancy by Tenant of the Building or the Premises, or any portion
     thereof; provided, however, that no such tax shall be treated as a "real
     property tax" unless the revenues generated by such tax are used
     exclusively for city, county or other local purposes, as opposed to state
     or federal purposes, and unless such tax is assessed only to the address of
     the Building (or all other buildings similarly situated) and not to
     Landlord generally without regard to its ownership of the Building;

          (iv)   any assessment, tax, fee, levy or charge upon this transaction
     or any document to which Tenant is a party creating or transferring an
     interest or an estate in the Premises, or based upon a reassessment of the

     transfer of all or part of Landlord's interest in this Lease, the
     Development, or any portion thereof.

     Notwithstanding any provision of this Subparagraph 6(a) expressed or
implied to the contrary, "real property taxes" shall not include Landlord's
federal or state income, franchise, inheritance or estate taxes.

     Notwithstanding any provision of this Subparagraph 6(a) to the contrary,
during the initial Term of the Lease only, "real property taxes" shall not
include any increase in real property taxes attributable to an assessment or
reassessment of the Building, Development, or any portion thereof due to (i) the
first Third Party Change in Ownership (as defined below) during the initial Term
with respect to such reassessed portion of the Building or Development, or (ii)
an Existing Owner Change in Ownership (as defined below)     

                                      -14-
<PAGE>
 
    
during the initial Term with respect to such reassessed portion of the Building
or Development which Existing Owner Change in Ownership occurs prior to the
first Third Party Change in Ownership with respect to such reassessed portion
of the Building or Development. The exclusion from real property taxes set forth
in the immediately preceding sentence shall not apply to any increase in real
property taxes attributable to a change in ownership (as defined in Rule 462 of
the Rules of the State Board of Equalization) ("Change in Ownership") of any
portion of the Building or Development which has previously been the subject of
a reassessment based upon a Third Party Change in Ownership. In addition, any
exclusion from real property taxes set forth in this paragraph shall not be
applicable during any extension of the initial 122 month Term of this Lease. An
"Existing Owner Change in Ownership" shall mean any Change in Ownership which
constitutes a transfer of legal or beneficial ownership of such applicable
portion of the Building or Development only among those persons or entities
which hold legal or beneficial (i.e., through ownership interests in other
entities) ownership in such applicable portion of the Building or Development as
of the date of this Lease. A "Third Party Change in Ownership" shall mean any
Change in Ownership other than an Existing Owner Change in Ownership.

     Landlord and Tenant agree that in determining Operating Expenses, only the
Building's Share (as defined below) of the Operating Expenses attributable to
the Common Areas shall be included in Operating Expenses hereunder. The
"Building Share" shall mean that portion of the operating expenses of the Common
Areas which is allocated to the Building pursuant to the CC&R's or Parking
CC&R's, or any amendment, modifications, supplements or replacements thereto or
thereof, to the extent such amendments, modifications, supplements or
replacements do not increase Tenant's rental obligations hereunder.

     Landlord and Tenant acknowledge that since the Building is part of a
larger, integrated Development, in many instances a pure segregation between
costs of operation of the Building and the remaining portions of the Development
may not be available. Consequently, except for Operating Expenses attributable
to the Common Areas which shall be allocated to the Building as provided in the
immediately preceding paragraph, in those instances in which a pure segregation
between costs of operation of the Building and other portions of the Development
is not available, a fair and equitable allocation of such costs shall be made
among the various buildings in the Development.     

                                      -15-
<PAGE>
 
    
     Operating Expenses shall be "net" only and for that purpose shall be deemed
reduced by the amounts of any insurance reimbursement, other reimbursement,
recoupment, payment, discount, credit, reduction, allowance or the like received
by Landlord from any source whatsoever in connection with such Operating
Expenses.

     Notwithstanding anything to the contrary contained in this Paragraph 6(a)
the following shall be excluded from the definition of Operating Expenses:

          (i)    repairs or other work occasioned by fire, windstorm or other
     insured casualty (except that deductibles paid pursuant to any insurance
     shall be included as Operating Expenses) or by the exercise of eminent
     domain, to the extent Landlord is reimbursed by insurance or by the
     condemning authority, or would have been so reimbursed if Landlord had
     maintained in force the insurance required to be carried by Landlord under
     the provisions of the Lease;

          (ii)   leasing commissions, attorneys' and other professional fees,
     costs and disbursements and other expenses incurred in connection with
     procuring new tenants and/or negotiations or disputes with present or
     prospective tenants or other occupants of the Building or the Development;

          (iii)  costs incurred in renovating or otherwise improving or
     decorating, painting or redecorating space leased to tenants or occupied by
     occupants of the Building;

          (iv)   Landlord's cost of electricity or other services that are sold
     to tenants for which Landlord is entitled to reimbursement, other than
     through the payment of rent or a tenant's prorata share of Operating
     Expenses;

          (v)    depreciation, amortization and interest payments, except as
     provided herein and except on materials, tools, supplies and vendor-type
     equipment purchased by Landlord to enable Landlord to supply services
     Landlord might otherwise contract for with a third party where such
     depreciation, amortization and interest payments would otherwise have been
     included in the charge for such third party's services, all as determined
     in accordance with generally accepted accounting principles, consistently
     applied, and when depreciation or amortization is permitted or required.

     capital costs which (i) reduce other Operating Expenses, amortized over the
     useful life of the asset, including interest at the Interest Rate, but only
     to the extent of the reduction of other Operating Expenses, (ii) are
     required under any governmental law or regulation that was not applicable
     to the Building at the time the Building was constructed, amortized over
     the useful life of the asset, with interest at the Interest Rate, or (iii)

     the Building;

          (ix)   overhead and profit increment paid to a subsidiary, affiliate
     or other entity related to Landlord for services to the extent the same
     exceed competitive costs (taking into account the quality of service
     provided in maintaining a Class-A office building) of such services were
     they not so rendered by a subsidiary, affiliate or other Landlord-related
     entity;

          (x)    interest on ____ or amortization payments on any mortgage or

     revenue; "gross revenue" shall mean the actual gross rent, operating
     expense escalations and parking revenues received by Landlord, grossed-up
     to reflect a ninety-five percent (95%) occupancy rate for the Building in
     the event that the Building occupancy rate is less than ninety-five (95%);
     provided, however, this clause (xv) shall not apply to any management or
     administrative fee applicable to the Common Areas and assessed or imposed
     against the Building pursuant to the CC&R's;

          (xvi)   acquisition costs of the sculptures, paintings, or other
     objects of art, except that Operating Expenses shall include maintenance of
     such items;

          (xvii)  wages, salaries or other compensation paid to any executive
     employees above the grade of building manager;

          (xviii) rentals and other related expenses, if any, incurred in
     leasing air conditioning systems, elevators or other equipment ordinarily
     considered to be of a capital nature;

          (xix)   any compensation paid to clerks, attendants, or other persons
     in commercial concessions operated by Landlord, except as it directly
     relates to the operation of the Development or the Parking Facilities;

          (xx)    capital expenditures required by Landlord's failure to comply
     with laws enacted on or before the date the Building's temporary
     Certificate of Occupancy is validly issued, with respect to the
     construction of the base building work, or enacted on or before the
     issuance of an occupancy permit for Tenant's occupancy of the Premises,
     with respect to the construction of the Tenant Improvements; and     

                                      -18-

          (xxi)   insurance premiums for earthquake coverage, unless earthquake
     coverage is carried by Landlord during the period of determination of the
     Operating Expense Allowance.

     Landlord shall not be permitted to "double recover" any operating Expenses
(i.e., recover more than 100% of Operating Expenses) from the tenants of the
Building.

     (b) If Tenant's Percentage of the Operating Expenses paid or incurred by
Landlord for any calendar year exceeds the Operating Expense Allowance, then
Tenant shall pay such excess as additional rent. For each calendar year during
the Term of the Lease, or portion thereof, Tenant shall pay Landlord's estimate
of the amount by which Tenant's Percentage of Operating Expenses for that year
shall exceed the Operating Expense Allowance, which estimate may be changed by
Landlord on not more than two (2) occasions during any calendar year. On or
before each April 1 following the calendar year in which the Term commences, or
as soon thereafter as reasonably practicable, Landlord shall deliver to Tenant
its estimate of the amount by which Tenant's Percentage of Operating Expenses is
projected to exceed the Operating Expense Allowance. Such estimate shall be
determined by Landlord in good faith, using reasonable business judgment, and
shall take into consideration any limitation on Controllable Costs set forth in
Subparagraph 6(d). Landlord's initial estimated amount each year shall be
divided into twelve (12) equal monthly installments. Commencing with the second
(2nd) Lease Year, Tenant shall pay to Landlord, concurrently with the regular
monthly rent payment next due following the receipt of the estimate for the
remaining calendar year of such second (2nd) Lease year, an amount equal to one
monthly installment multiplied by the number of months from the first (1st)
anniversary of the Commencement Date to the month of such payment, both months
inclusive. Subsequent installments shall be payable concurrently with the
regular monthly rent payments for the balance of that calendar year and shall
continue until the next calendar year's or any revised estimate is rendered. If
during any year Landlord revises its previous estimate, any such revision shall
be applied prospectively only; provided, however, that such prospective
application shall not prevent Landlord from recovering from Tenant, upon
delivery of its statement of actual Operating Expenses for the previous year,
the amount, if any, by which Tenants Percentage Share of actual Operating
Expenses exceeds Landlord's estimates     

                                      -19-
<PAGE>
 
    
thereof, as described below. If, in any calendar year, Tenant's Percentage of
actual Operating Expenses is less than the estimate for that year, then upon
receipt of Landlord's statement, any overpayment made by Tenant on the monthly
installment basis shall be credited towards the next monthly rent falling due
(or, at Tenant's request, repaid to Tenant) and the estimated monthly
installments of the amount by which Tenant's Percentage of Operating Expenses
exceeds the Operating Expense Allowance shall be adjusted to reflect such lower
Operating Expenses for the most recent calendar year. Similarly, if Tenant's
Percentage of the actual Operating Expenses for any calendar year is greater
than that previously estimated by Landlord for such year, Tenant shall pay the
amount of such difference to Landlord on the regular monthly rent payment date
next following Tenant's receipt of Landlord's statement of actual Operating
Expenses.

     (c) Even though the Term has expired and Tenant has vacated the Premises,
when the final determination is made of Tenant's Percentage of Operating
Expenses for the year in which this Lease terminates, Tenant shall immediately
pay any increase due over the estimated expenses paid and, conversely, any
overpayment made in the event said expenses decrease shall be immediately
rebated by Landlord to Tenant.

     (d) Commencing with the first (1st) anniversary of the Commencement Date
and continuing thereafter to and including the sixtieth (60th) month of the Term
of the Lease, the portion of Operating Expenses which constitute "Controllable
Costs" (as defined below) shall not increase over such four (4) year period at
an average rate in excess of five percent (5%) per annum. During the period from
months sixty-one (61) through ninety (90) of the Term of the Lease, Controllable
Costs shall not increase beyond the "Secondary Cap". The "Secondary Cap" shall
mean an average rate per annum equal to the greater of (i) five percent (5%) per
annum, or (ii) the average annual cost of living increase between the first
(1st) month and the sixtieth (60th) month of the Term of this Lease (which shall
be determined by comparing the Consumer Price Index - Urban Wage Earners and
Clerical Workers - Los Angeles-Anaheim-Riverside, California, Base 1982-84
("CPI") compiled by the U.S. Department of Labor, Bureau of Labor Statistics,
for month one (1) with the CPI for month sixty (60), and dividing any such total
increase by five (5)). During the period from months ninety-one (91) through
one-hundred twenty-two (122) of the Term of the Lease, Controllable Costs shall
not increase beyond the "Final Cap". The "Final Cap" shall mean an average rate
per annum of the greater of (x) the Secondary Cap, or (y) the average annual CPI
increase between the sixty-first (61st) month through the ninetieth (90th) month
     

                                      -20-
<PAGE>
 
    
of the Term of the Lease. The rate specified in clause (y) shall be computed by
comparing the CPI for month sixty-one (61) of the Term with the CPI for month
ninety (90) of the Term and dividing any such total increase by 2.5. For
purposes of illustration, if the total CPI increase from the first (1st) month
of the Term to the sixtieth (60th) month of the Term is thirty-five percent
(35%), then the Secondary Cap shall be seven percent (7%). Similarly, if the
total CPI increase from the sixty-first (61st) to the ninetieth (90th) month of
the Term is twenty percent (20%), the Final Cap shall be eight percent (8%).
"Controllable Costs" shall mean all Operating Expenses which can increase or
decrease at the independent and sole discretion of Landlord, as opposed to
increases or decreases which are industry-wide or are caused by third parties or
over which Landlord has no independent control. By way of illustration but not
limitation, Operating Expenses over which Landlord has no independent and sole
discretion include any Operating Expenses paid to a public utility, insurer and
taxing authority for utilities, insurance, real property taxes, and costs of
operating, maintaining and repairing the Building, Common Areas and Parking
Facilities at the level of a Qualified Building (as defined in Paragraph 55) as
required by this Lease, as contrasted with the cost of operating, maintaining
and repairing the Building, Common Areas and Parking Facilities at a level below
that of a Qualified Building. If the parties disagree upon whether a specific
Operating Expense is a Controllable Cost, such disagreement shall be submitted
to arbitration in accordance with the provisions of the American Arbitration
Association. Landlord agrees that approximately every two (2) years Landlord
shall rebid the janitorial, security, landscape and parking service contracts
for the Building.

     (e) In the event Tenant shall dispute the amount set forth in Landlord's
statement of actual Operating Expenses for the previous year (or the statement
setting forth the Operating Expense Allowance), Tenant shall have the right not
later than ninety (90) days following receipt of such statement to notify
Landlord in writing that Tenant intends to examine Landlord's books and records
with respect to both the calendar year described in such statement and the
calendar year immediately preceding the calendar year described in such
statement, and, if Tenant elects, shall also have the right within such ninety
(90) day period to notify Landlord in writing that Tenant intends to cause
Landlord's books and records with respect to such two (2) calendar years
described above to be audited by a certified public accountant mutually
acceptable to Landlord and Tenant. Any such examination or audit shall be
performed at Landlord's offices during normal business hours and shall be
completed within ninety (90) days following Tenant's notice     

                                      -21-

described above. The amounts payable under Subparagraph 6(b) by Landlord to
Tenant or by Tenant to Landlord, as the case may be, shall be appropriately
adjusted on the basis of such audit. If such audit discloses an overstatement by
Landlord of Operating Expenses for the particular calendar year(s) which is the
subject of the audit in excess of five percent (5%) of the aggregate actual
Operating Expenses for such year(s), the cost of such audit shall be borne by
Landlord; otherwise, the cost of such audit shall be borne by Tenant. Tenant
shall have no right to audit the Operating Expenses unless Tenant complies with
the time limitations regarding notice and completion of such audit set forth in
this Subparagraph 6(e) and if Tenant shall fail to comply with such time
limitations, Landlord's actual statement of Operating Expenses respecting any
time period as to which Tenant's audit rights have lapsed shall be conclusively
binding upon Landlord and Tenant.

     8. USE.

     (a) Tenant's Use of the Premises. Tenant shall use the Premises for the
uses set forth in Subparagraph 1(v) above, and shall not use or permit the
Premises to be used for any other purpose without the prior written consent of
Landlord. Nothing contained herein shall be deemed to give Tenant any exclusive
right to such use in the Building, the Parking Facilities (other than Tenant's
right to use its reserved parking spaces pursuant to Paragraph 40) or any
portion of the Development.

     (b) Compliance.

          (i) Tenant shall not use or occupy the Premises in violation of law or
     of the Certificate of Occupancy issued for the Building, and shall, upon
     written notice from Landlord, discontinue any use of the Premises which is
     declared by any governmental authority having jurisdiction to be a
     violation of law or of said Certificate of Occupancy. The Certificate of
     Occupancy shall not prevent Tenant from using the Premises for general
     office purposes. Tenant shall comply with any direction of any governmental
     authority having jurisdiction which shall, by reason of the nature of
     Tenant's use or occupancy of the Premises, impose any duty upon Tenant or
     Landlord with respect to the Premises or with respect to the use or
     occupation thereof. Tenant shall comply with all rules, orders, regulations
     and requirements of the Pacific Fire Rating Bureau or any other
     organization performing a similar function; provided, however, Landlord
     agrees that the provisions of this sentence shall not interfere with
     Tenant's occupancy of the Premises for general office use. Tenant shall
     promptly, upon demand, reimburse Landlord for any additional premium
     charged for such policy by reason of Tenant's failure to comply with the
     provisions of this Paragraph. Tenant shall not do or permit anything to be
     done in or about the Premises     

                                     -23-
<PAGE>
 
    
     which will in any way obstruct or interfere with the rights of other
     tenants or occupants of the Building, the Parking Facilities or the
     Development, or injure them, or use or allow the Premises to be used for
     any unlawful purpose, nor shall Tenant cause, maintain or permit any
     nuisance in, on or about the Premises. Tenant shall comply with all
     restrictive covenants and obligations created by private contracts which
     affect the use and operation of the Premises, the Building, the Parking
     Facilities, the Common Areas or the Development. Landlord agrees that,
     subject to any such private contracts or provisions thereof as are required
     by applicable law, any such private contracts entered into after the date
     of this Lease shall be nondiscriminatory and shall not unreasonably
     interfere with Tenant's use of or access to the Premises or materially
     increase Tenant's obligations under the Lease. Tenant shall not commit or
     suffer to be committed any waste in or upon the Premises and shall keep the
     Premises in first class repair and appearance. Landlord reserves the right
     to prescribe the weight and position of all files, safes and heavy
     equipment which Tenant desires to place in the Premises so as to properly
     distribute the weight thereof in accordance with the structural
     requirements of the Building. Further, Tenant's business machines and
     mechanical equipment which cause vibration or noise that may be transmitted
     to the Building structure or to any other space in the Building shall be so
     installed, maintained and used by Tenant as to eliminate such vibration or
     noise. Tenant shall be responsible for all structural engineering required
     to determine structural load. 

          (ii) Tenant shall not cause or permit any hazardous, toxic or
     radioactive materials, including those materials identified in Sections
     66680 through 66685 of Title 22 of the California Administrative Code,
     Division 4, Chapter 30, as amended from time to time ("Hazardous
     Materials"), to be brought upon, kept or used in or about the Premises, the
     Building, the Parking Facilities or the Common Areas by Tenant, its agents,
     employees, contractors or invitees, unless such Hazardous Materials (in
     incidental quantities) are necessary or useful to Tenant's business and
     will be used, kept and stored in a manner that complies with all laws
     regulating any such Hazardous Materials, and provided that Tenant first
     obtains the written consent of Landlord and the owner(s) and/or operator(s)
     of the Parking Facilities and Common Areas, and provided further that
     Tenant indemnifies Landlord, and the owner(s) and operator(s) of the
     Parking Facilities and     

                                     -24-
<PAGE>
 
    
     Common Areas from any and all liability with respect to such Hazardous
     Materials as more particularly described below. If Tenant breaches the
     covenants and obligations set forth herein or, if the presence of Hazardous
     Materials on, in or about the Premises, the Building, the Parking
     Facilities, the Common Areas or any other portion of the Development caused
     or permitted by Tenant, its agents, employees, contractors or invitees,
     results in contamination of the Premises, the Building, the Parking
     Facilities, the Common Areas or any other portion of the Development or, if
     contamination of the Premises, the Building, the Parking Facilities, the
     Common Areas or any other portion of the Development by Hazardous Materials
     otherwise occurs for which Tenant is legally liable to Landlord, the
     owner(s) or operator(s) of the Parking Facilities and/or the Common Areas,
     whether jointly or severally, for damage resulting therefrom, then Tenant
     shall indemnify, defend and hold Landlord and the owner(s) and operator(s)
     of the Parking Facilities and the Common Areas free and harmless from and
     against any and all claims, judgments, damages, penalties, fines, costs,
     liabilities and losses (including, without limitation, diminution in the
     value of the Premises, the Parking Facilities and/or the Common Areas,
     damages for the loss or restriction on use of rentable or useable space or
     of any amenity of the Premises, the Building, the Common Areas or any other
     portion of the Development, and sums paid in settlement of claims,
     attorneys' fees, consultant fees and expert fees) which arise during or
     after the Lease Term as a result of such contamination. This
     indemnification by Tenant of Landlord, the owner(s) and operator(s) of the
     Parking Facilities and the Common Areas, includes without limitation, any
     and all costs incurred in connection with any investigation of site
     conditions or any clean up, remedial, removal or restoration work required
     by any federal, state or local governmental agency or political subdivision
     because of the presence of such Hazardous Material in, on or about the
     Premises, the Building, the Parking Facilities, the Common Areas or the
     soil or ground water on or under the Development.

          (iii) The provisions of this Paragraph 8 shall survive the termination
     of this Lease.

     9. NOTICES. Any notice required or permitted to be given hereunder must be
in writing and may be given by personal delivery or by mail, and if given by
mail shall be deemed sufficiently given if sent by registered or certified mail
addressed if to Tenant, at the address set forth in ______________________ if
such notice is sent prior to Tenant taking     

                                     -25-
<PAGE>
 
    
occupancy of the Premises, or to the Premises, if such notice is sent on or
after Tenant taking occupancy of the Premises, or if to Landlord, at each of the
addresses ________________________________________. Either party may specify a
different address for notice purposes by written notice to the other, except
that on or after Tenant taking occupancy of the Premises, the Landlord may in
any event use the Premises as Tenant's address for notice purposes.

     10. BROKERS. Landlord and Tenant each warrant to the other party that it
has had no dealings with any real estate broker or agent in connection with the
negotiation of this Lease, except for those certain brokers whose names are set
forth in ___________ whose commission shall be payable by Landlord, and that
it knows of no other real estate broker or agent who is or might be entitled to
a commission in connection with this Lease. If either party has dealt with any
other person or real estate broker with respect to leasing or renting space in
the Building, such party shall be solely responsible for the payment of any fee
due said person or firm and shall hold the other party free and harmless against
any liability in respect thereto, including attorneys' fees and costs.

     11. HOLDING OVER. If Tenant holds over after the expiration or earlier
termination of the Term hereof with the express written consent of Landlord,
Tenant shall become a Tenant at sufferance only, at a rent rate equal to one
hundred fifty percent (150%) of the rent in effect upon the date of such
expiration (subject to adjustment as provided in Paragraphs 5 and 6 hereof and
prorated on a daily basis), and otherwise subject to the terms, covenants and
conditions herein specified, so far as applicable. Acceptance by Landlord of
rent after such expiration or earlier termination shall not result in a renewal
of this Lease. The foregoing provisions of this Paragraph 11 are in addition to
and do not affect Landlord's right of re-entry or any rights of Landlord
hereunder or as otherwise provided by law. If Tenant fails to surrender the
Premises upon the expiration of this Lease despite demand to do so by Landlord,
Tenant shall indemnify and hold Landlord harmless from all loss or liability,
including without limitation, any claim made by any succeeding tenant founded on
or resulting from such failure to surrender and any attorneys' fees and costs.

     12. TAXES ON TENANT'S PROPERTY.

          (a) Tenant shall be liable for and shall pay, at least ten (10) days
     before delinquency, all taxes levied against any personal property or trade
     fixtures placed by Tenant in or about the Premises. If any such taxes on
     Tenant's personal property or trade fixtures are levied against Landlord or
     Landlord's property or if the assessed value of the Premises is increased
     by the inclusion therein     

                                     -26-
<PAGE>
 
    
     of a value placed upon such personal property or trade fixtures of Tenant
     and if Landlord, after written notice to Tenant, pays the taxes based upon
     such increased assessment, which Landlord shall have the right to do
     regardless of the validity thereof, but only under proper protest if
     requested by Tenant, Tenant shall, upon demand, repay to Landlord the taxes
     so levied against Landlord, or the portion of such taxes resulting from
     such increase in the assessment.

          (b) If the Tenant Improvements in the Premises, whether installed,
     and/or paid for by Landlord or Tenant and whether or not affixed to the
     real property so as to become a part thereof, are assessed for real
     property tax purposes at a valuation higher than the valuation at which
     tenant improvements conforming to Landlord's "Building Standard" for other
     space in the Building are assessed, then the real property taxes and
     assessments levied against the Building by reason of such excess assessed
     valuation shall be deemed to be taxes levied against personal property of
     Tenant and shall be governed by the provisions of Paragraph 12(a) above. If
     the records of the County Assessor are available and sufficiently detailed
     to serve as a basis for determining whether the Tenant Improvements are
     assessed at a higher valuation than "Building Standard" improvements, such
     records shall be binding on both Landlord and Tenant. If the records of the
     County Assessor are not available or sufficiently detailed to serve as a
     basis for making said determination, the actual cost of construction shall
     be used. Notwithstanding any contrary provision of this Subparagraph 12(b),
     the provisions of this Subparagraph 12(b) shall be applicable only to the
     extent the cost of the Tenant Improvements initially installed in the
     Premises, or any alterations made thereto by or on behalf of Tenant during
     the Term exceeds Thirty Dollars ($30.00) per Usable Square Foot of the
     Premises.

     13. CONDITION OF PREMISES. Tenant acknowledges that neither Landlord nor
any agent of Landlord has made any representation or warranty with respect to
the Premises, the Building, the Parking Facilities or any other portion of the
Development or with respect to the suitability of same for the conduct of
Tenant's business. The taking of possession of the Premises by Tenant shall
conclusively establish that the Premises, the Building and the Parking
Facilities were in satisfactory condition at such time, subject to the approved
punch-list items, and latent defects, which Landlord shall promptly repair.
Landlord agrees to enforce all applicable warranty obligations of contractors
and materialmen in connection with the construction of the Building and
Premises. Without limiting the foregoing, Tenant's execution of the Notice
attached hereto as Exhibit "C" shall constitute a specific acknowledgment     

                                     -27-
<PAGE>
 
    
and acceptance of the various start-up inconveniences that may be associated
with the use of the Building, the Parking Facilities, the Common Areas and other
portions of the Development such as certain construction obstacles including
scaffolding, delays in use of freight elevator service, certain elevators not
being available to Tenant, the passage of work crews using elevators, uneven air
conditioning services and other typical conditions incident to recently
constructed office buildings; provided, however, that such inconveniences shall
not materially interfere with Tenant's use of or access to the Premises.

     14. ALTERATIONS.

          (a) Tenant shall make no alterations, additions or improvements in or
     to the Premises without Landlord's prior written consent, which consent
     shall not be unreasonably withheld or delayed, and then only by contractors
     or mechanics reasonably approved by Landlord, which approval shall not be
     unreasonably delayed. Tenant shall submit to Landlord plans and
     specifications for any proposed alterations, additions or improvements to
     the Premises, and may not make such alterations, additions or improvements
     until Landlord has approved of such plans and specifications. Tenant shall
     construct such alterations, additions or improvements in accordance with
     the plans and specifications approved by Landlord, and shall not amend or
     modify such plans and specifications without Landlord's prior written
     consent, which consent shall not be unreasonably withheld or delayed. If
     the proposed change requires the consent or approval of any lessor of a
     superior lease, or the holder of a mortgage encumbering the Premises, such
     consent or approval must be secured prior to the construction of such
     alteration, addition or improvement. Tenant agrees that there shall be no
     construction of partitions or other obstructions which might interfere with
     Landlord's free access to mechanical installations or service facilities of
     the Building or interfere with the moving of Landlord's equipment to or
     from the enclosures containing said installations or facilities. All such
     work shall be done at such times and in such manner as Landlord may from
     time to time designate. Tenant covenants and agrees that all work done by
     Tenant shall be performed in full compliance with all laws, rules, orders,
     ordinances, regulations and requirements of all governmental agencies,
     offices and boards having jurisdiction, and in full compliance with the
     rules, regulations and requirements of the Pacific Fire Rating Bureau, and
     of any similar body. Before commencing any work, Tenant shall give Landlord
     at least ten (10) days written notice of the proposed commencement of such
     work and shall, if reasonably required by Landlord based upon the
     reputation and financial capability of the contractor and the nature 
     of     

                                     -28-
<PAGE>
 
    
     the work to be performed (including Landlord's particular reasons
     therefor), secure at Tenant's own post and expense, a completion and lien
     indemnity bond reasonably satisfactory to Landlord for said work. Tenant
     further covenants and agrees that any mechanic's lien filed against the
     Premises or against the Building for work claimed to have been done for, or
     materials' claimed to have been furnished to Tenant, will be discharged by
     Tenant, by bond or otherwise, within twenty (20) days after the filing
     thereof, at the cost and expense of Tenant, except that Tenant shall not be
     obligated to so discharge such lien prior to ten (10) days following
     Tenant's receipt of notice of the existence thereof. As long as Tenant
     properly discharges the lien by bond or otherwise, as provided above,
     Tenant shall have the right to contest such lien in accordance with
     applicable law. All alterations, additions or improvements upon the
     Premises made by either party, including (without limiting the generality
     of the foregoing) all wallcovering, built-in cabinet work, paneling and
     the like, shall, unless Landlord elects otherwise, become the property of
     Landlord, and shall remain upon, and be surrendered with the Premises, as a
     part thereof, at the end of the Term hereof, except that Landlord may, by
     written notice to Tenant at the time Landlord consents to such alteration,
     or within twenty (20) days after receipt of notice thereof, if no consent
     is required, require Tenant to remove at the end of the Term, all
     partitions, counters, railings and the like installed by Tenant, and Tenant
     shall repair all damage resulting from such removal or, at Landlord's
     option, shall pay to Landlord all costs arising from such removal.
     Notwithstanding any contrary provision of this Subparagraph 14(a),
     Landlord's prior consent shall not be required for any nonstructural
     alteration to the Premises, the cost of which does not exceed Thirty
     Thousand Dollars ($30,000.00), as long as such alteration does not affect
     the structural integrity of the Building, does not adversely affect the
     Building systems and is not visible from the exterior of the Premises;
     provided, however, all other provisions of this Subparagraph 14(a) shall be
     applicable to any such alteration, including, but not limited to Tenant's
     obligation to provide Landlord with prior written notice of any such
     alteration, along with the plans and specifications related thereto, if
     appropriate.

          (b) All articles of personal property and all business and trade
     fixtures, machinery and equipment, furniture and movable partitions owned
     by Tenant or installed by Tenant at its expense in the Premises shall be
     and remain the property of Tenant and may be removed by Tenant at any time
     during the Lease Term when Tenant is not in default hereunder, or within
     fifteen (15) days following the end of such Lease Term. If Tenant shall
     fail to remove all of its     

                                     -29-

     effects from the Premises within fifteen (15) days after termination of
     this Lease for any cause whatsoever, Landlord may, at its option, remove
     the same in any manner that Landlord shall choose, and store said effects
     without liability to Tenant for loss thereof. In such event, Tenant agrees
     to pay Landlord upon demand any and all expenses incurred in such removal,
     including court costs and attorneys' fees and storage charges on such
     effects, for any length of time that the same shall be in Landlord's
     possession. Landlord may, at its option, without notice, sell said effects,
     or any of the same, at private sale and without legal process, for such
     price as Landlord may obtain and apply the proceeds of such sale upon any
     amounts due under this Lease from Tenant to Landlord and upon the expense
     incident to the removal and sale of said effects.

     15. REPAIRS.

          (a) By entry hereunder, Tenant accepts the Premises as being in good
     and sanitary order, condition and repair. Tenant shall keep, maintain and
     preserve the Premises in first class condition and repair and free from any
     Hazardous Materials, and shall, when and if needed, at Tenant's sole cost
     and expense, but subject to the provisions of Subparagraph 15(b) below,
     make all repairs to the Premises and every part thereof. Tenant's
     obligation to keep, maintain, preserve and repair the Premises shall
     specifically extend to the cleanup and removal of all Hazardous Materials
     occurring in, on or about the Premises, the Building, the Parking
     Facilities or any other portion of the Development, caused or permitted by
     Tenant, its agents, employees, contractors or invitees. Tenant shall, upon
     the expiration or sooner termination of the Term hereof, surrender the
     Premises to Landlord in the same condition as when received, free of any
     Hazardous Materials, usual and ordinary wear and tear and casualty
     excepted. Landlord shall have no obligation to alter, remodel, improve,
     repair, decorate or paint the Premises or any part thereof. The parties
     hereto affirm that Landlord has made no representations to Tenant
     respecting the condition of the Premises, the Building, the Parking
     Facilities or the Common Areas except as specifically herein set forth.

          (b) Anything contained in Paragraph 15(a) above to the contrary
     notwithstanding, Landlord shall repair and maintain or cause to be repaired
     and maintained, in a first class condition the structural portions of the
     Building and the Parking Facilities, and the plumbing, heating,
     ventilating, air conditioning, elevator and electrical systems installed or
     furnished by Landlord, unless such maintenance and repairs are attributable
     to items installed     

                                     -30-
<PAGE>
 
    
     in Tenant's Premises which are above standard interior improvements (such
     as, for example, custom lighting, kitchen or restroom facilities
     constructed within Tenant's Premises) or, are caused in part or in whole by
     the act, neglect or omission of any duty by Tenant, its agents, servants,
     employees or invitees, in which case Tenant shall pay to Landlord, as
     additional rent, the reasonable cost of such maintenance and repairs.
     Landlord shall not be liable for any failure to make any such repairs or to
     perform any maintenance unless such failure shall persist for an
     unreasonable time after written notice of the need of such repairs or
     maintenance is given to Landlord by Tenant. Except as provided in
     Paragraphs 23 and 64 hereof, there shall be no abatement of rent and no
     liability of Landlord 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 or ordinance
     now or hereafter in effect. Landlord agrees that all necessary repairs to
     items located in the Premises which do not serve the Premises but
     exclusively serve other tenants' premises shall be made after normal
     business hours, so as to minimize interference with Tenant's use and
     occupancy of the Premises.

     16. LIENS. Tenant shall not permit to be filed against the Building or any
portion of the Development nor against Tenant's leasehold interest in the
Premises, any mechanics', materialmen's or other liens, including, without
limitation, any state, federal or local "super-fund" or Hazardous Material
cleanup lien imposed as a result of the presence of Hazardous Materials in, on
or about the Premises, the Building or any other portion of the Development.
Landlord shall have the right at all reasonable times to post and keep posted on
the Premises any notices which it deems necessary for protection from such
liens. If any such liens are filed, Landlord may, without waiving its rights and
remedies based on such breach of Tenant and without releasing Tenant from any of
its obligations, cause such liens to be released by any means it shall deem
proper, including payments in satisfaction of the claim giving rise to such
lien. Tenant shall pay to Landlord at once, upon notice by Landlord, any sum
paid by Landlord to remove such liens, together with interest at the maximum
rate per annum permitted by law from the date of such payment by Landlord.

     17. ENTRY BY LANDLORD. Landlord reserves and shall at any and all times
have the right to enter the Premises upon not less than twenty-four (24) hours
prior notice, except in the case of an emergency, to inspect the same, to supply
janitor service and any other service to be provided by Landlord to     

                                      -31-
<PAGE>
 
    
Tenant hereunder, to show the Premises to prospective purchasers or tenants, to
post notices of nonresponsibility, to alter, improve or repair the Premises or
any other portion of the Building and/or the Parking Facilities, all without
being deemed guilty of any eviction of Tenant and, except as otherwise provided
in Paragraph 64, without abatement of rent. Landlord may, in order to carry out
such purposes, erect scaffolding and other necessary structures where reasonably
required by the character of the work to be performed, provided that the
business of Tenant shall be interfered with as little as is reasonably
practicable. Tenant hereby waives any claim for damages for any injury or
inconvenience to or interference with Tenant's business, any loss of occupancy
or quiet enjoyment of the Premises, and any other loss in, upon and about the
Premises. Landlord shall at all times have and retain a key with which to unlock
all doors in the Premises, excluding Tenant's vaults, safes and other security
areas. Landlord shall have the right to use any and all means which Landlord may
deem proper to open said doors in an emergency in order to obtain entry to the
Premises. Any entry to the Premises obtained by Landlord by any of said means,
or otherwise, shall not be construed or deemed to be a forcible or unlawful
entry into the Premises, or an eviction of Tenant from the Premises or any
portion thereof, and any damages caused on account thereof shall be paid by
Tenant. It is understood and agreed that no provision of this Lease shall be
construed as obligating Landlord to perform any repairs, alterations or
decorations except as otherwise expressly agreed herein by Landlord. Except in
the event of an emergency, Tenant shall have the right to have one of its
personnel accompany Landlord on any entry by Landlord to the Premises.
Landlord's absolute right of entry to the Premises to show the Premises to
prospective tenants shall be limited to the last year of the Term; provided,
that at all other times Tenant shall use its commercially reasonable efforts to
cooperate with Landlord's reasonable requests to display the Premises to
prospective tenants.

     18. UTILITIES AND SERVICES. Landlord agrees to furnish or cause to be
furnished to the Premises the utilities and services described in the Standards
for Utilities and Services, attached hereto as Exhibit "D", subject to the
conditions and in accordance with the standards set forth therein. Landlord's
failure to furnish any of the foregoing items when such failure is caused by (i)
accident, breakage or repairs; (ii) strikes, lockouts or other labor disturbance
or labor dispute of any character; (iii) governmental regulation, moratorium or
other governmental action; (iv) inability despite the exercise of reasonable
diligence to obtain electricity, water or fuel; or by (v) any other cause beyond
Landlords reasonable control, shall not result in any liability to Landlord. In
addition, subject to the provisions, of Paragraph 64, Tenant shall not be
entitled to     

                                      -32-
<PAGE>
 
    
any abatement or reduction of rent by reason of such failure, no eviction of
Tenant shall result from such failure and Tenant shall 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 shall
diligently attempt to resume service promptly. If Tenant requires or utilizes
more water than reasonably required for normal drinking and lavatory purposes,
as specified in Paragraph 4 of Exhibit "D", or utilizes more electricity than
the standard electrical consumption specified in Paragraph 3 of Exhibit "D",
Landlord may at its option require Tenant to pay, as additional rent, the cost,
as fairly determined by Landlord, incurred by such extraordinary usage. In
addition, if Tenant utilizes excess water or electricity as described above, and
continues such excess use after written notice thereof by Landlord, then upon an
additional prior written notice to Tenant Landlord may install separate meter(s)
for the Premises, at Tenant's sole expense, and Tenant thereafter shall pay all
charges of the utility providing service and Landlord shall make an appropriate
adjustment to Tenant's Operating Expenses calculation to account for the fact
Tenant is directly paying such metered charges, provided Tenant shall remain
obligated to pay its proportionate share of Operating Expenses subject to such
adjustment.

     19. BANKRUPTCY. If Tenant shall file a petition in bankruptcy under any
provision of the Bankruptcy Code as then in effect, or if Tenant shall be
adjudicated a bankrupt in involuntary bankruptcy proceedings and such
adjudication shall not have been vacated within ninety (90) days from the date
thereof, or if a receiver or trustee of Tenant's property shall be appointed and
the order appointing such receiver or trustee shall not be set aside or vacated
within ninety (90) days after the entry thereof, or if Tenant shall assign
Tenant's estate or effects for the benefit of creditors, or if this Lease shall,
by operation of law or otherwise, pass to any person or persons other than
Tenant, then in any such event Landlord may terminate this Lease, if Landlord so
elects, with or without notice of such election and with or without entry or
action by Landlord. In such case, notwithstanding any other provisions of this
Lease, Landlord, in addition to any and all rights and remedies allowed by law
or equity, shall, upon such termination, be entitled to recover damages in the
amount provided in Paragraph 25(b) hereof. Neither Tenant nor any person
claiming through or under Tenant or by virtue of any statute or order of any
court shall be entitled to possession of the Premises but shall surrender the
Premises to Landlord. Nothing contained herein shall limit or prejudice the
right of Landlord to recover damages by reason of any such termination equal to
the maximum allowed by any statute or rule of law in effect at the time when,
and governing the     

                                     -33-
<PAGE>
 
    
proceedings in which, such damages are to be proved; whether or not such amount
is greater, equal to or less than the amount of damages recoverable under the
provisions of this Paragraph 19.

     20. EXONERATION.

          (a) Except as set forth in Subparagraphs 20(c) and 21(a) below, due
     to the gross negligence or willful misconduct of Landlord or its agents,
     employees or invitees, Landlord shall not be liable to Tenant for any loss
     or damage to Tenant's personal property in the Premises (or outside the
     Premises to the extent insured by Tenant and not insured by Landlord with
     insurance paid for as part of Operating Expenses) caused by theft, fire,
     act of God, acts of the public enemy, riot, strike, insurrection, war,
     court order, requisition or order of governmental body or authority or for
     any damage or inconvenience which may arise through repair or alteration of
     any part of the Building or Development or failure to make any such repair
     except as expressly otherwise provided in Subparagraph 20(c) and elsewhere
     herein. Tenant shall not be liable to Landlord for any loss or damage to
     property caused by theft, fire, act of God, acts of the public enemy, riot,
     strike, insurrection, war, court order, requisition or order of
     governmental body or authority or for any damage or destruction which is
     covered by insurance obtained, or would have been covered by insurance
     required to be obtained, by Landlord as part of Operating Expenses. Neither
     Landlord nor Tenant shall be liable for consequential damages.

          (b) Tenant shall indemnify Landlord and hold Landlord harmless of and
     from any and all loss, cost, damage, injury or expense arising out of or
     related to claims of injury to or death of persons occurring or resulting
     directly or indirectly from Tenant's use or occupancy of the Premises or
     activities of Tenant in or about the Premises or Development, such
     indemnity to include, but without limitation, the obligation to provide all
     costs of defense against any such claims; provided, however, that the
     foregoing indemnity shall not be applicable to claims arising by reason of
     the negligence or willful misconduct of Landlord, its agents, employees or
     invitees unless covered by insurance required to be carried by Tenant under
     the terms of the Lease.

          (c) Landlord shall indemnify Tenant and hold Tenant harmless of and
     from any and all loss, cost, damage, injury or expense arising out of or
     related to claims or injury to or death of persons, or damage to property
     occurring or resulting directly or indirectly from the use or operation of
     the Building, Parking Facilities, or the Common     

                                     -34-
<PAGE>
 
    
     Areas by Landlord or the owner or operator thereof (or activities of
     Landlord which occur outside the Premises, but within the Development),
     such indemnity to include, but without limitation, the obligation to
     provide all costs of defense against any such claim.

     21. INDEMNIFICATION.

          (a) Notwithstanding the provisions of Paragraphs 20 to the contrary,
     because Landlord is required to maintain insurance on the Building and the
     Tenant Improvements and all alterations, additions or improvements to the
     Premises and Tenant compensates Landlord for such insurance as part of
     Tenant's Percentage of Operating Expenses, and to the extent of the
     existence of waivers of subrogation set forth in Paragraph 22(f) of this
     Lease, Landlord hereby indemnifies and holds Tenant harmless from any loss,
     cost, liability, damage or expense (including, but not limited to,
     penalties, fines and reasonable, actual attorneys' fees and costs) to any
     person or property inside or outside of the Premises to the extent such
     loss, costs, liability, damage or expenses are covered by such insurance
     obtained by Landlord (or which would have been covered by insurance
     required to be obtained by Landlord hereunder had Landlord complied with
     its obligation to so maintain insurance in accordance with this Lease),
     even if resulting from the negligent acts or omissions of Tenant or those
     of its agents, contractors, servants, employees or licensees. Similarly,
     since Tenant must carry insurance pursuant to Paragraph 22(a) of this Lease
     to cover its personal property within the Premises but excluding the Tenant
     Improvements and all alterations, additions or improvements to the
     Premises, then, to the extent of the waivers of subrogation set forth in
     Paragraph 22(f) of this Lease, Tenant hereby indemnifies and holds Landlord
     harmless from any loss, cost, liability, damage or expense (including, but
     not limited to, penalties, fines and reasonable, actual attorneys' fees and
     costs) to any personal property within the Premises or the Development, to
     the extent such loss, costs, liability, damage or expenses are covered by
     such insurance obtained by Tenant (or would have been covered by insurance
     required to be maintained by Tenant hereunder had Tenant complied with its
     obligation to so maintain insurance in accordance with this Lease), even if
     resulting from the negligent acts or omissions of Landlord or those of its
     agents, contractors, servants, employees or licensees.

          (b) Notwithstanding the provisions of Paragraph 20 to the contrary,
     Tenant shall not be required to indemnify and hold Landlord harmless from
     any loss, cost, liability, damage or expense, including, but not limited
     to, penalties,     

                                     -35-
<PAGE>
 
    
     fines and actual attorneys' fees and costs (collectively, "Claims"), to any
     person, property or entity resulting from the acts, omissions or the
     willful misconduct of Landlord or its agents, contractors, servants,
     employees or licensees or other owners or operators of the Parking
     Facilities or Common Areas, in connection with the use or operation of the
     Building, parking Facilities, or Common Areas by Landlord or the owners or
     operators thereof (except for damage to Tenant's personal property,
     fixtures, furniture and equipment in the Premises, to the extent that
     Tenant is required to obtain the requisite insurance coverage, and to the
     extent that the waiver of subrogation applies), and Landlord hereby so
     indemnifies and saves Tenant harmless from any such Claims. However,
     Tenant's agreement to indemnity and hold Landlord harmless pursuant to
     Paragraph 20, the exclusion from Tenant's indemnity set forth above, and
     the agreement by Landlord to indemnify and hold Tenant harmless set forth
     above are not intended to, and shall not, except to the extent to which the
     waiver of subrogation provision applies, relieve any insurance carrier of
     its obligations under policies required to be carried by Landlord or
     Tenant, respectively, pursuant to the provisions of this Lease to the
     extent that such policies cover the results of such acts or conduct. The
     parties hereby agree that if either party fails to carry required
     insurance, such failure shall automatically be deemed to be the covenant
     and agreement by such party to self-insure said required coverage, with
     full waiver of subrogation in favor of the other party. The parties further
     agree that to the extent any damage or repair obligation of Tenant is
     covered by insurance obtained by Landlord or would have been covered by
     insurance had Landlord maintained the insurance required to be maintained
     by Landlord under this Lease as part of the Operating Expenses, but is not
     covered by insurance obtained by Tenant, then Tenant shall be relieved of
     its indemnity obligation up to the amount of the insurance proceeds which
     Landlord shall actually receive (or would have received had Landlord
     maintained insurance as aforesaid)

     22. INSURANCE.

          (a) Tenant shall, during the Term hereof and any other period of
     occupancy, at its sole cost and expense, keep in full force and effect the
     following insurance:

               (i) Standard form property insurance insuring against the perils
          of fire, extended coverage, vandalism, malicious mischief, special
          extended coverage ("All-Risk") and sprinkler leakage. This insurance
          policy shall be upon all property owned by Tenant, for which Tenant is
          legally liable or that was installed at     

                                     -36-
<PAGE>
 
    
          Tenant's expense, and which is located in the Building including,
          without limitation, furniture, fittings, installations, fixtures
          (other than Tenant Improvements installed by Landlord), and any other
          personal property, in an amount not less than one hundred percent
          (100%) of the full replacement cost thereof. In the event that there
          shall be a dispute as to the amount which comprises full replacement
          cost, the decision of Landlord or any mortgagees of Landlord shall be
          conclusive. Such policy shall name Landlord and any mortgagees of
          Landlord as insured parties, as their respective interests may appear.

               (ii)  Commercial Liability Insurance insuring Tenant against any
          liability arising out of the lease, use, occupancy or maintenance of
          the Premises and all areas appurtenant thereto. Such insurance shall
          be in the amount of $5,000,000 Combined Single Limit for injury to, or
          death of one or more persons in an occurrence, and for damage to
          tangible property (including loss of use) in an occurrence, with such
          liability amount to be adjusted from year to year to reflect increases
          in the Consumer Price Index. The policy shall include coverage against
          personal injury, bodily injury (including wrongful death), broad form
          property damage, operations hazard, Owner's protective coverage,
          contractual liability, liquor liability (if Tenant serves alcohol on
          the Premises), products and completed operations liability, and
          owned/non-owned auto liability, and shall (1) name Landlord as an
          additional insured, (2) contain a cross liability provision and (3)
          contain a provision that the insurance provided the Landlord hereunder
          shall be primary and non-contributing with any other insurance
          available to the Landlord.

               (iii) Worker's Compensation and Employer's Liability insurance
          (as required by state law).

               (iv)  To the extent not included in Tenant's insurance carried in
          satisfaction of clause (i) above or otherwise covered by blanket
          coverage, boiler and machinery insurance including, but not limited
          to, steam pipes, pressure pipes, condensation return pipes and other
          pressure vessels and HVAC equipment with limits per accident of not
          less than the replacement cost of all of Tenant's leasehold
          improvements and of all of Tenant's boilers, pressure valves, HVAC
          equipment and miscellaneous electrical and mechanical equipment on the
          Premises.     

                                     -37-
<PAGE>
 
    
               (v)  Business interruption insurance which shall cover any direct
          or indirect loss of earnings attributable to perils insured against in
          Subparagraph 22(a)(i) above; provided, however, Tenant shall have the
          right to self-insure the coverage described in this clause (v). In
          the event Tenant elects to self-insure such coverage, such
          self-insured coverage shall be deemed to include all the provisions of
          this paragraph 22 which would have been required to be applicable to
          such coverage if Tenant had obtained such coverage from a third party,
          including full waiver of subrogation.

               (vi) If commonly required from time to time by the landlords of
          the Qualified Buildings, 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.

          (b) All policies shall be written in a form satisfactory to Landlord
     and shall be taken out with insurance companies holding a rating typically
     required by the landlords of the Qualified Buildings. Within ten (10) days
     prior to Tenant's entry into the Premises for Tenant's Fixturing Work (as
     defined in Paragraph 9 of Exhibit "B"), but in any event not later than ten
     (10) days prior to the Commencement Date, Tenant shall deliver to Landlord
     copies of policies or certificates evidencing the existence of the amounts
     and forms of coverage satisfactory to Landlord. No such policy shall be
     cancellable or reducible in coverage except after thirty (30) days prior
     written notice to Landlord. Tenant shall, within ten (10) days prior to the
     expiration of such policies, furnish Landlord with renewals or "binders"
     thereof, or Landlord may order such insurance and charge the cost thereof
     to Tenant as additional rent. If Landlord obtains any insurance that is the
     responsibility of Tenant under this Paragraph 22, Landlord shall deliver to
     Tenant a written statement setting forth the cost of any such insurance and
     showing in reasonable detail the manner in which it has been computed and
     Tenant shall promptly remit said amount to Landlord. Tenant shall be
     permitted to satisfy any insurance coverage required hereunder, or any
     portion thereof, with blanket coverage as long as such coverage satisfies
     all the requirements of this Lease and Landlord's rights with respect
     thereto are not affected thereby.

          (c) During the Term of this Lease, Landlord shall insure the Building
     and the Parking Facilities (to the extent Landlord is the owner thereof)
     (excluding any property which     

                                     -38-
<PAGE>
 
    
     Tenant is obligated to insure under Subparagraphs 22(a) and (b) hereof)
     against damage with All-Risk insurance and public liability insurance, all
     in such amounts and with such deductibles as commonly carried by other
     landlords of the Qualified Buildings. Landlord may, but shall not be
     obligated to, obtain and carry any other commercially reasonable form or
     forms of insurance as it or Landlord's mortgagees may determine advisable.
     Notwithstanding any contribution by Tenant to the cost of insurance
     premiums, as provided herein, Tenant acknowledges that it has no right to
     receive any proceeds from any insurance policies carried by Landlord. For
     the purpose of the waiver of subrogation provisions set forth in
     Subparagraph 22(f) below, Landlord shall be deemed to have carried the
     insurance required under this Subparagraph 22(c) in an amount equal to full
     replacement value, with a commercially reasonable deductible.

          (d) Tenant will not keep, use, sell or offer for sale in or upon the
     Premises any article which may be prohibited by any insurance policy
     periodically in force covering the Building, the Parking Facilities or the
     Development. If Tenant's occupancy or business in, or on, the Premises,
     whether or not Landlord has consented to the same, results in any increase
     in premiums for the insurance periodically carried by Landlord with respect
     to the Building or the Parking Facilities, Tenant shall pay any such
     increase in premiums as additional rent within ten (10) days after being
     billed therefor by Landlord. In determining whether increased premiums are
     a result of Tenant's use of the Premises, a schedule issued by the
     organization computing the insurance rate on the Building, the Parking
     Facilities or the Tenant Improvements showing the various components of
     such rate, shall be conclusive evidence of the several items and charges
     which make up such rate. Notwithstanding any contrary provision of this
     Subparagraph 22(d), Landlord's insurance policies shall not prevent Tenant
     from using the Premises for general office purposes, nor shall Tenant be
     required to directly pay any increased premiums under this Subparagraph
     22(d) due to Tenant's use of the Premises for general office use. Tenant
     shall promptly comply with all reasonable requirements of the insurance
     authority or any present or future insurer relating to the Premises.

          (e) If any of Landlord's insurance policies shall be cancelled or
     cancellation shall be threatened or the coverage thereunder reduced or
     threatened to be reduced in any way because of the use of the Premises or
     any pact thereof by Tenant or any assignee or subtenant of Tenant or by
     anyone Tenant permits on the Premises, Tenant shall remedy the condition
     giving rise to such cancellation, threatened cancellation, reduction of
     coverage, threatened reduction of     

                                     -39-

     coverage, increase in premiums, or threatened increase in premiums on or
     before the later of (i) ten (10) days prior to the effective date of such
     cancellation, coverage reduction or premium increase, or (ii) forty-eight
     (48) hours after notice thereof from Landlord. If Tenant fails to remedy
     such condition within the above time period, Landlord may (x) enter upon
     the Premises and attempt to remedy such condition, and Tenant shall
     promptly pay the cost thereof to Landlord as additional rent, or (y) in the
     event that such insurance carrier has notified Landlord in writing of its
     intention to cancel or reduce its coverage, terminate the Lease. Subject to
     the provisions of Paragraphs 20 and 21, Landlord shall not be liable for
     any damage or injury caused to any property of Tenant or of others located
     on the Premises resulting from such entry. If Landlord is unable, or elects
     not to remedy such condition, then Landlord shall have all of the remedies
     provided for in this Lease in the event of a default by Tenant.
     Notwithstanding the foregoing provisions of this Subparagraph 22(e), if
     Tenant fails to remedy as aforesaid, Tenant shall be in default of its
     obligation hereunder and Landlord shall have no obligation to remedy such
     default.

          (f) All policies of insurance required hereunder shall include a
     clause or endorsement denying the insurer any rights of subrogation against
     the other party to the extent rights have been waived by the insured before
     the occurrence of injury or loss. Landlord and Tenant waive any rights of
     recovery against the other for injury or loss due to hazards covered by
     policies of insurance containing such a waiver of subrogation clause or
     endorsement to the extent of the injury or loss covered thereby.

     23. DAMAGE OR DESTRUCTION.

          (a) In the event the Building and/or the Premises is damaged by fire
     or other perils covered by Landlord's insurance, Landlord shall:

               (i) In the event of damage or destruction to the Building to an
          extent exceeding twenty-five percent (25%) of the full insurable value
          of the Building, or damage or destruction to the Premises to an extent
          exceeding thirty-three percent (33%) of the full insurable value of
          the Premises, as applicable, at Landlord's option, as soon as
          reasonably possible thereafter, commence repair, reconstruction and
          restoration of the Building and/or the Premises and prosecute the same
          diligently to completion, in which event this Lease shall remain in
          full force and effect; or within ninety (90) days after such damage,
          elect not     

                                     -40-
<PAGE>
 
    
          to so repair, reconstruct or restore the Building and/or the Premises,
          in which event this Lease shall terminate; provided, however, in the
          event of a casualty which includes material damage or destruction to
          portions of the Building outside of the Premises, Landlord shall not
          be entitled to selectively terminate this Lease unless Landlord also
          elects to terminate the leases of all tenants similarly situated,
          other than Wells Fargo or any other tenants in the Building whose
          lease may not permit such a termination, but such restriction on
          Landlord's termination of the Lease shall not result in Landlord's
          expending more for the repair and/or reconstruction of such damage
          than the proceeds from Landlord's insurance required hereunder plus
          permitted deductibles. In either event, Landlord shall give Tenant
          written notice of its intention within said ninety (90) day period. In
          the event Landlord elects not to restore the Building and/or the
          Premises, this Lease shall be deemed to have terminated as of the date
          of such total destruction.

               (ii) In the event of a partial destruction which constitutes
          neither damage to the Building to an extent exceeding twenty-five
          percent (25%) of the full insurable value of the Building, nor damage
          to the Premises to an extent exceeding thirty-three percent (33%) of
          the full insurable value of the Premises, and if the damage is such
          that the Building and the Premises may be repaired, reconstructed or
          restored within a period of six (6) months from the date of the
          happening of such casualty, as determined by an independent qualified
          third party and if Landlord will receive (or if Landlord would have
          carried the insurance required hereunder, would have received)
          insurance proceeds sufficient to cover the cost of such repairs, less
          the deductibles described in Paragraph 22(c), commence and proceed
          diligently with the work of repair, reconstruction and restoration and
          this Lease shall continue in full force and effect. If such work of
          repair, reconstruction and restoration shall require a period longer
          than six (6) months or exceeds the applicable percentage of full
          insurable value set forth above, or if said insurance proceeds
          (determined assuming Landlord carried the insurance coverage required
          hereunder) will not be sufficient to cover the cost of such repairs,
          less the deductible described in Paragraph 22(c), then Landlord either
          may elect to so repair, reconstruct or restore and the Lease shall
          continue in full force and effect or Landlord may elect not to repair,
          reconstruct or restore and the Lease shall then terminate; provided,
          however, in the event of     

                                     -41-
<PAGE>
 
    
          a casualty which includes material damage or destruction to portions
          of the Building outside of the Premises, Landlord shall not be
          entitled to selectively terminate this Lease unless Landlord also
          elects to terminate the leases of all tenants similarly situated,
          other than Wells Fargo or any other tenant in the Building whose lease
          may not permit such a termination, but such restriction on termination
          of the Lease shall not result in Landlord's expending more for the
          repair and/or reconstruction of such damage than the proceeds from
          Landlord's insurance required hereunder, plus permitted deductibles;
          provided, further, in the event that Landlord elects not to repair the
          damage or destruction and to terminate the Lease solely on the basis
          of an inadequacy of insurance proceeds as provided above, then Tenant
          shall have the right, by written notice to Landlord within twenty (20)
          days following Landlord's termination notice, to nullify Landlord's
          termination notice by agreeing to pay for the amount by which the cost
          of repair or restoration (less deductibles described in Paragraph
          22(c)) exceeds Landlord's insurance proceeds (calculated assuming
          Landlord had maintained the required insurance hereunder). The
          projected cost to be paid by Tenant shall be deposited into escrow
          prior to the commencement of repair or reconstruction work. Under any
          of the conditions of this Subparagraph 23(a)(ii), Landlord shall give
          written notice to Tenant of its intention within said ninety (90) day
          period. In the event Landlord elects not to restore the Building
          and/or the Premises, this Lease shall be deemed to have terminated as
          of the date of such partial destruction.

          (b) Upon any termination of this Lease under any of the provisions of
     this Paragraph 23, the parties shall be released without, further
     obligation to the other from the date possession of the Premises is
     surrendered to Landlord except for items which have heretofor accrued and
     are then unpaid.

          (c) In the event of repair, reconstruction or restoration by Landlord
     of the Premises, Building or Parking Facilities as herein provided, the
     rent payable under this lease shall be abated proportionately with the
     degree to which Tenant's use of the Premises is impaired during the period
     of such repair, reconstruction or restoration. Tenant shall not be entitled
     to any compensation or damages for loss in the use of the whole or any part
     of the Premises and/or any inconvenience or annoyance occasioned by such
     damage, repair, reconstruction or restoration.     

                                     -42-
<PAGE>
 
    
          (d) Notwithstanding anything to the contrary contained in this
     Paragraph 23, if all or any part of the Premises or Building is damaged or
     destroyed, and if Landlord is unable, within ninety (90) days following
     such damage or destruction, to provide Tenant with a certificate from
     Landlord's general contractor stating that Tenant will be given reasonable
     use of, and access to, a fully-repaired and restored Premises within one
     (1) year of the damage or destruction, Tenant may terminate this Lease upon
     ten (10) days' written notice to Landlord, given at any time within thirty
     (30) days following the earlier of (i) the end of such ninety (90) day
     period or (ii) the date upon which Landlord notifies Tenant that Landlord
     does not intend to or is not able to deliver the above-described
     certificate to Tenant.

          (e) In the event that the Parking Facilities are damaged or destroyed
     due to casualty, and if Landlord is unable, within thirty (30) days
     following such damage or destruction, to provide Tenant with a good faith,
     reasonable assurance that Tenant can be given reasonable use of, and access
     to, its parking privileges in the Parking Facilities specified herein, or
     use of and access to substitute parking within the Development within a
     reasonable walking distance to the Building (or temporary parking as
     provided below), on or before the later of (i) sixty (60) days after such
     damage or destruction or, (ii) if the Building has been damaged or
     destroyed, concurrent with Landlord's restoration of the Building, then
     Tenant shall have the right to terminate this Lease upon ten (10) days'
     written notice to Landlord, given at any time within sixty (60) days after
     the date of the casualty. Tenant agrees that Landlord shall have the right
     during any reasonable repair or reconstruction period to temporarily
     relocate Tenant's parking privileges to a parking facility served by a
     Landlord provided shuttle. During any period during which Tenant is denied
     access to its parking privileges in the Parking Facilities due to damage or
     destruction to the Parking Facilities and Landlord does not provide
     replacement parking as provided herein, a prorata portion of Tenant's
     parking charges herein shall abate based upon the proportion of such
     parking privileges which Landlord fails to replace. In the event that the
     Parking Facilities are damaged or destroyed and due to Landlord's election
     not to repair the Parking Facilities Tenant's parking privileges are
     permanently relocated as provided herein, Tenant's parking charges shall be
     subject to equitable reduction in the event that the quality and/or
     location of Tenant's new parking facilities are not commensurate with the
     Parking Facilities.

          (f) If Landlord is obligated to or elects to repair or restore as
     herein provided, Landlord shall be     

                                     -43-
<PAGE>
 
    
     obligated to make repair or restoration only of those portions of the
     Building and the Premises which were originally provided at Landlord's
     expense, and the repair and restoration of items not provided at Landlord's
     expense shall be the obligation of Tenant.

          (g) Notwithstanding anything to the contrary contained in this
     Paragraph 23, either Landlord or Tenant shall have the right to terminate
     this Lease in the event of damage or destruction to the Premises which
     occurs during the last twelve (12) months of the Term of this Lease or any
     extension hereof, if such damage or destruction cannot reasonably be
     repaired within sixty (60) days after the date thereof.

          (h) The provisions of California Civil Code Section 1932, Subsection
     2, and Section 1933, Subsection 4, and any other similarly enacted statute
     or court decision relating to the abatement or termination of a lease upon
     destruction of the leased premises, are hereby waived by Tenant; and the
     provisions of this Paragraph shall govern in case of such destruction.

     24. EMINENT DOMAIN.

          (a) In case all of the Premises, Building or Parking Facilities or
     such part thereof as shall substantially interfere with Tenants access to
     or intended use and occupancy of the Premises, shall be taken for any
     public or quasi-public purpose by any lawful power or authority by exercise
     of the right of appropriation, condemnation or eminent domain, or sold to
     prevent such taking, either party shall have the right to terminate this
     Lease effective as of the date possession is required to be surrendered to
     said authority; provided, however, Tenant shall not have the right to
     terminate this Lease due to a taking of the Parking Facilities, as long as
     Landlord shall replace that portion of Tenant's parking privileges affected
     by such taking with other parking facilities within a reasonable distance
     from the Premises. Tenant shall not assert any claim against Landlord or,
     except as otherwise provided below, the taking authority, for any
     compensation because of such taking, and Landlord shall be entitled to
     receive the entire amount of any award; provided, however, Tenant shall be
     entitled to fifty percent (50%) of any portion of the award attributable to
     the bonus value of Tenant's leasehold estate. In the event the amount of
     property or the type of estate taken shall not substantially interfere with
     the conduct of Tenant's business, Landlord shall be entitled to the entire
     amount of the award without deduction for any estate or interest of Tenant,
     Landlord     

                                     -44-
<PAGE>
 
    
     shall restore the Premises to substantially their same condition prior to
     such partial taking, and a proportionate allowance shall be made to Tenant
     for the rent corresponding to the time during which, and to the part of the
     Premises of which, Tenant shall be so deprived on account of such taking
     and restoration. Nothing contained in this Subparagraph shall be deemed to
     give Landlord any interest in any award made to Tenant for the taking of
     personal property and fixtures belonging to Tenant, Tenant's goodwill or
     moving expenses incurred in connection with the relocation of Tenant's
     business. In the event that Landlord permanently relocates Tenant's parking
     due to a taking of the Parking Facilities, Tenant's parking charges shall
     be subject to equitable reduction in the event that the quality and/or
     location of Tenant's new parking facilities are not commensurate with the
     Parking Facilities.

          (b) In the event of taking of the Premises or any part thereof for
     temporary use, (i) this Lease shall be and remain unaffected thereby and
     rent shall not abate, and (ii) Tenant shall be entitled to receive for
     itself such portion or portions of any award made for such use with respect
     to the period of the taking which is within the Term, provided that if such
     taking shall remain in force at the expiration or earlier termination of
     this Lease, Tenant shall then pay to Landlord a sum equal to the reasonable
     cost of performing Tenant's obligations under Paragraph 15 with respect to
     surrender of the Premises and upon such payment shall be excused from such
     obligations. For purpose of this Subparagraph 24(b), a temporary taking
     shall be defined as a taking for a period of 270 days or less.

     25. DEFAULTS AND REMEDIES.

          (a) The occurrence of any one or more of the following events shall
     constitute a default hereunder by Tenant:

               (i)  The abandonment of the Premises by Tenant as defined in
          California Civil Code Section 1951.3.

               (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 shall continue for a
          period of five (5) days after written notice thereof from Landlord to
          Tenant; provided, however, that any such notice shall be in lieu of,
          and not in addition to, any notice required under California Code of
          Civil Procedure Section 1161 regarding unlawful detainer actions or
          any similar successor statute.     

                                     -45-
<PAGE>
 
    
               (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 25(a)(i) or (ii) above, where such failure shall continue
          for a period of thirty (30) days after written notice thereof from
          Landlord to Tenant. Any such notice shall be in lieu of, and not in
          addition to, any notice required under California Code of Civil
          Procedure Section 1161 regarding unlawful detainer actions or any
          similar successor statute. If the nature of Tenant's default is such
          that more than thirty (30) days are reasonably required for its cure,
          then Tenant shall not be deemed to be in default if Tenant shall
          commence such cure within said thirty (30) day period and thereafter
          diligently prosecute such cure to completion.

               (iv)   (1) The making by Tenant of any general assignment for the
          benefit of creditors; (2) 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 ninety (90) days); (3) 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 ninety (90) days; or (4)
          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 ninety (90)
          days.

          (b) In the event of any such default by Tenant, in addition to any
     other remedies available to Landlord at law or in equity, including,
     without limitation, the remedies of Civil Code Section 1951.4 and any
     successor statute, Landlord shall have the immediate option to terminate
     this Lease and all rights of Tenant hereunder. In the event that Landlord
     shall elect to so terminate this Lease then 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     

                                     -46-
<PAGE>
 
    
               (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
          Tenant's obligations under this Lease or which in the ordinary course
          of things would be likely to result therefrom.

          As used in Subparagraphs 25(b)(i) and (ii) above, the "worth at the
     time of award" is computed by allowing interest at the maximum rate
     permitted by law. As used in Subparagraph 25(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) In the event of any such default by Tenant, Landlord shall 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 at
     the cost of and for the account of Tenant. No re-entry or taking possession
     of the Premises by Landlord pursuant to this Paragraph 25(c) shall 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) In the event of the vacation or abandonment of the Premises by
     Tenant or in the event that Landlord shall elect to re-enter as provided
     above or shall take possession of the Premises pursuant to legal proceeding
     or pursuant to any notice provided by law, then if Landlord does not elect
     to terminate this Lease as provided above, Landlord may from time to time,
     without terminating this Lease, either recover all rent as it becomes due
     or relet the Premises or any part thereof for the Term of this Lease on
     terms and conditions as Landlord in its sole discretion may deem advisable
     with the right to make alterations and repairs to the Premises.

          In the event that Landlord shall elect to so relet, then rents
     received by Landlord from such reletting shall 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;
     fourth, to the payment of rent due and unpaid hereunder and     

                                     -47-
<PAGE>
 
    
     the residue, if any, shall 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 shall pay such
     deficiency to Landlord immediately upon demand therefor by Landlord. Such
     deficiency shall be calculated and paid monthly. Tenant shall also pay to
     Landlord, as soon as ascertained, any costs and expenses incurred by
     Landlord in such reletting or in making such alterations and repairs not
     covered by the rents received from such reletting.

          (e) All rights, options and remedies of Landlord contained in this
     Lease shall be construed and held to be cumulative, and no one of them
     shall 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, whether or not stated in this Lease. No waiver of
     any default of Tenant hereunder shall be implied from any acceptance by
     Landlord of any rent or other payments due hereunder or any omission by
     Landlord to take any action on account of such default if such default
     persists or is repeated, and no express waiver shall affect defaults other
     than as specified in said waiver. The consent or approval of Landlord to or
     of any act by Tenant requiring Landlord's consent or approval shall not be
     deemed to waive or render unnecessary Landlord's consent or approval to or
     of any subsequent similar acts by Tenant.

     26. ASSIGNMENT AND SUBLETTING.

          (a) Tenant shall not voluntarily or by operation of law, assign,
     encumber or transfer its interest in this Lease or in the Premises or
     sublease all or any part of the Premises, or allow any other person or
     entity to occupy or use all or any part of the Premises, without first
     obtaining Landlord's prior written consent, which consent Landlord shall
     not unreasonably withhold or delay. Any assignment, encumbrance or sublease
     without Landlord's prior written consent shall be voidable at Landlord's
     election and shall constitute a default.

          (b) For purposes hereof, if Tenant is a corporation (other than a
     publicly-held corporation), partnership or other entity, any transfer,
     assignment, encumbrance or hypothecation of forty-nine percent (49%) 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,
     shall be deemed     

                                     -48-

     an assignment of this Lease and shall be subject to all of the restrictions
     and provisions contained in this Paragraph 26; provided, however, no sale
     of all of Tenant's stock reasonably approved by Landlordshall be subject to
     the provisions of this Paragraph 26. No consent to an assignment,
     encumbrance or sublease shall constitute a further waiver of the provisions
     of this Paragraph 26.

          (c) In the event Tenant desires to assign, hypothecate or otherwise
     transfer this Lease or sublet the Premises, then at least thirty days prior
     to the date when Tenant desires the assignment or sublease to be effective
     (the "Assignment Date"), Tenant shall give Landlord a notice (the
     "Assignment Notice"), which shall set forth the name, address and business
     of the proposed assignee or sublessee, information (including references)
     concerning the character, ownership, and financial condition of the
     proposed assignee or sublessee, the Assignment Date, any ownership or
     commercial relationship between Tenant and the proposed assignee or
     sublessee, and the consideration and all, other material terms and
     conditions of the proposed assignment or sublease, all in such detail as
     Landlord shall reasonably require. If Landlord reasonably requests
     additional detail, the Assignment Notice shall not be deemed to have been
     received until Landlord receives such additional detail, and Landlord may
     withhold consent to any assignment or sublease until such information is
     provided to it.

          (d) Within thirty (30) days of Landlord's receipt of such Assignment
     Notice, and additional information requested by Landlord concerning the
     proposed assignee's or sublessee's financial responsibility, Landlord shall
     elect to either consent to such proposed assignment, encumbrance or
     sublease or refuse such consent, which refusal shall be on reasonable
     grounds. In addition, a condition to Landlord's consent to any assignment,
     transfer or hypothecation of this Lease shall be the delivery to Landlord
     of a true copy of the fully executed instrument of assignment, transfer or
     hypothecation, and the delivery to Landlord of an agreement executed by the
     assignee in form and substance satisfactory to Landlord and expressly
     enforceable by Landlord, whereby the assignee assumes and agrees to be
     bound by all of the terms and provisions of this Lease and to perform all
     of the obligations of Tenant hereunder. As a condition to Landlord's
     consent to any sublease, such sublease shall provide that it is subject and
     subordinate to this Lease and to all mortgages; that Landlord may enforce
     the provisions the sublease, including collection of rent; that in the
     event of termination of this Lease for any reason, including     

                                     -49-
<PAGE>
 
    
     without limitation a voluntary surrender by tenant, or in the event of any
     reentry or repossession of the Premises by Landlord, Landlord may, at its
     option, either (i) terminate the sublease or (ii) take over all of the
     right, title and interest of Tenant, as sublessor, under such sublease, in
     which case such sublessee shall attorn to Landlord, but that nevertheless
     Landlord shall not (1) be liable for any previous act or omission of Tenant
     under such sublease, (2) be subject to any defense or offset previously
     accrued in favor of the sublessee against Tenant, or (3) be bound by any
     previous modification of any sublease made without Landlord's written
     consent, or by any previous prepayment by sublessee of more than one
     month's rent.

          (e) Landlord shall be deemed reasonable in withholding its consent
     based upon any of the following factors: (i) the financial net worth of the
     proposed assignee or sublessee is not equal to or greater than Tenant's
     financial net worth as of the date of this Lease as increased by the
     increase in the CPI, if any, between the date of this Lease and the date of
     the assignment or sublease; (ii) the intended use of the Premises by the
     proposed assignee or sublessee is incompatible with other uses in the
     Building; (iii) the intended use of the Premises by the proposed assignee
     or sublessee will require more than insignificant alteration of the
     Premises; or (iv) the intended use of the Premises by the proposed assignee
     or sublessee will constitute a violation of this Lease or any governmental
     law, rule, ordinance or regulation governing the Premises or the Building
     or would involve the storage, use or keeping of Hazardous Materials in, on
     or about the Premises, the Building, the Parking Facilities, the Common
     Areas or any other portion of the Development.

          (f) In the event that Landlord shall consent to an assignment or
     sublease under the provisions of this Paragraph 26, Tenant shall pay
     Landlord's processing costs and attorneys' fees incurred in giving such
     consent. If Landlord shall consent to any assignment of this Lease, Tenant
     shall pay to Landlord, as additional rent, fifty percent (50%) of all sums
     and other consideration payable to and for the benefit of Tenant by the
     assignee on account of the assignment ("Assignment Transfer profits"), as
     and when such sums and other consideration are due and payable by the
     assignee to or for the benefit of Tenant (or, if Landlord so requires, and
     without any release of Tenant's liability for the same, Tenant shall
     instruct the assignee to pay such sums and other consideration directly to
     Landlord). If for any proposed sublease Tenant receives rent or other
     consideration, either initially or over the Term of the sublease, in excess
     of the rent called for hereunder or, in     

                                     -50-
<PAGE>
 
    
     case of the sublease of a portion of the Premises, in excess of such rent
     fairly allocable to such portion, after appropriate adjustments to assure
     that all other payments called for hereunder are taken into account, Tenant
     shall pay to Landlord as additional rent hereunder fifty percent (50%) of
     the excess of each such payment of rent or other consideration received by
     Tenant (the "Sublease Transfer Profits") promptly after its receipt.
     Notwithstanding any contrary provision of this Subparagraph 26(f), in
     determining Assignment Transfer Profits or Sublease Transfer Profits,
     Tenant shall be entitled to deduct advertising costs, brokerage
     commissions, improvement allowances and/or retrofit costs, legal fees, and
     space planning fees incurred by Tenant in assigning the Lease or subleasing
     the Premises. Landlord's waiver or consent to any assignment or subletting
     shall not relieve Tenant or any assignee or sublessee from any obligation
     under this Lease whether or not accrued. Occupancy of all or part of the
     Premises by parent or subsidiary companies of Tenant shall not be deemed an
     assignment or subletting.     

                                     -51-
<PAGE>
 
    
          (h) Notwithstanding any provision of this paragraph 26 to the
     contrary, Tenant shall have the right upon prior written notice to
     Landlord, to sublease all or any portion of the Premises to (i) an entity
     resulting from a merger or a consolidation with Tenant or any organization
     purchasing substantially all of Tenant's assets, (ii) any entity succeeding
     to substantially all of the business and assets of Tenant, or (iii) any
     corporation which controls, is controlled by or is under common control
     with, Tenant ((i), (ii) and (iii) hereafter referred to as "Affiliate
     Subtenant(s)"), without first obtaining Landlord's consent; provided,
     however, Tenant shall remain responsible for the performance of the Lease;
     and provided, further, Tenant shall give Landlord prior notice of any such
     sublease. Landlord shall not have the right to receive from Tenant any
     portion of the Transfer Profits on a sublease or an assignment to an
     Affiliate Subtenant, nor shall the provisions of Subparagraph 26(g) above
     be applicable to any such sublease. No sublease to an Affiliate Subtenant
     shall relieve Tenant from any obligation under this Lease.

     27. SUBORDINATION.

          (a) 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 with a lien on the Building or the Development or
     any ground lessor with respect to the Building or the Development, this
     Lease shall 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, the Development, or
          the land upon which the Building and the Development are situated, or
          both; and

               (ii)   the lien of any mortgage or deed of trust which may now
          exist or hereafter be executed in any amount for which the Building,
          the Development, the land upon which the Building and the Development
          are situated, ground leases or underlying leases, or Landlord's
          interest or estate in any of said items is specified as security.

     Notwithstanding the foregoing, Landlord shall have the right to subordinate
     or cause to be subordinated any such ground leases or underlying leases or
     any such liens to this Lease.     

                                     -52-
<PAGE>
 
    
     In the event that any ground lease or underlying lease terminates for any
     reason or any mortgage or deed of trust is foreclosed or a conveyance in
     lieu of foreclosure is made for any reason, Tenant shall, notwithstanding
     any subordination, attorn to and become the Tenant of the successor-in-
     interest to Landlord, at the option of such successor-in-interest. Tenant
     covenants and agrees to execute and deliver, upon demand by Landlord and in
     a commercially reasonable form, any additional documents evidencing the
     priority or subordination of this Lease with respect to any such ground
     leases or underlying leases or the lien of any such mortgage or deed of
     trust. Should Tenant fail to sign and return any such documents within ten
     (10) business days of written request, Tenant shall be in default and
     Landlord shall have the right to send Tenant a notice, entitled "Lease
     Termination Notice", notifying Tenant that Landlord intends to terminate
     the Lease unless Tenant signs and returns the requested document within ten
     (10) business days following the date of such Lease Termination Notice. If
     Landlord delivers such Lease Termination Notice and Tenant fails to sign
     and return such requested document within such additional ten (10) business
     day period, Landlord shall thereafter have the right to terminate the Lease
     by notice to Tenant at any time within thirty (30) days following the date
     of the Lease Termination Notice. No such termination of the Lease by
     Landlord shall relieve the Tenant of any liability for a default by Tenant
     under this Lease. Notwithstanding any contrary provision of Subparagraph
     25(a), Tenant's failure to sign and deliver the documents required
     hereunder within ten (10) business days after the Lease Termination Notice
     shall constitute an event of default under the provisions of Subparagraph
     25(a) of the Lease, without any additional opportunity to cure.

          (b) Landlord agrees that prior to the commencement of the Term of the
     Lease it will provide Tenant with commercially reasonable non-disturbance
     agreements in favor of Tenant from any ground lessors, mortgage holders or
     lien holders then in existence, which shall be in recordable form and which
     may, at Tenant's election and expense, be recorded. Landlord also agrees to
     provide Tenant with commercially reasonable non-disturbance agreements in
     favor of Tenant from any ground lessors, mortgage holders or lien holders
     of Landlord who later come into existence at any time during the Term of
     this Lease, in consideration of, and as a condition to, Tenant's agreement
     to be bound by the provisions of Subparagraph 27(a) above. Tenant hereby
     waives the provisions of any current or future statute, rule or law which
     may give or purport to give Tenant any right to elect to terminate or
     otherwise adversely affect this Lease and the obligations of Tenant
     hereunder in the event of any foreclosure proceeding or sale, and agrees
     that this Lease     

                                     -53-
<PAGE>
 
    
     shall not be affected in any way whatsoever by any such foreclosure
     proceeding or sale, except that this sentence shall not affect Landlord's
     obligation to provide commercially reasonable non-disturbance agreements to
     Tenant.

     28. ESTOPPEL CERTIFICATE.

          (a) Within ten (10) business days following any written request which
     Landlord may make from time to time, Tenant shall execute and deliver to
     Landlord a statement, in a form substantially similar to the form of
     Exhibit "E" attached hereto, certifying: (i) the date of commencement of
     this Lease; (ii) the fact that this Lease is unmodified and in full force
     and effect (or, if there have been modifications hereto, that this Lease is
     in full force and effect, and stating the date and nature of such
     modifications); (iii) the date to which the rent and other sums payable
     under this Lease have been paid; (iv) that there are no current defaults
     under this Lease by either Landlord or Tenant except as specified in
     Tenant's statement; and (v) such other matters requested by Landlord.
     Landlord and Tenant intend that any statement delivered pursuant to this
     Paragraph 28 may be relied upon by any mortgagee, beneficiary, purchaser or
     prospective purchaser of the Building or any interest therein.

          (b) Tenant's failure to deliver such statement within such time shall
     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. Tenant's failure
     to deliver said statement to Landlord within ten (10) working days of
     receipt shall constitute a default under this Lease and Landlord shall have
     the right to send Tenant a notice, entitled "Lease Termination Notice",
     notifying Tenant that Landlord intends to terminate the Lease unless Tenant
     delivers said statement to Landlord within ten (10) business days following
     the date of such Lease Termination Notice. If Landlord delivers such Lease
     Termination Notice and Tenant fails to deliver said statement to Landlord
     within such ten (10) business day period, Landlord shall thereafter have
     the right to terminate the Lease by notice to Tenant at any time within
     thirty (30) days following the date of the Lease Termination Notice. No
     such termination of the Lease by Landlord shall relieve the Tenant of any
     liability for a default by Tenant under this Lease. Notwithstanding any
     contrary provision of Subparagraph 25(a), Tenant's failure to deliver said
     statement within ten (10) business days after the Lease Termination Notice
     shall     

                                     -54-
<PAGE>
 
    
     constitute an event of default under the provisions of Subparagraph 25(a)
     of the Lease without any additional opportunity to cure.

     29. LANDLORD ESTOPPEL CERTIFICATE. Landlord shall, within ten (10) business
days following written notice by Tenant from time to time, execute and deliver
to Tenant a statement in writing prepared by Tenant and edited by Landlord as
appropriate, certifying that this Lease is unmodified and in full force and
effect (or if there have been modifications hereto, that this Lease is in full
force and effect as modified, and stating the date and nature of such
modifications), the dates to which Tenant has paid rent, adjustments to rent,
and other charges in advance, if any, stating whether or not to the actual
knowledge of Landlord, Tenant is in default in the performance of any covenant,
agreement or condition contained in this Lease, and if so, specifying each such
default of which Landlord may have knowledge, or containing any other
information or certifications which reasonably may be requested by Tenant, any
proposed assignee or sublessee of Tenant or any proposed lender of Tenant. Any
such statement delivered pursuant to this Paragraph 29 may be relied upon by any
proposed assignee or sublessee or any proposed lender of Tenant. Landlord's
failure to deliver such statement within such time period shall be conclusive
upon Landlord (i) that this Lease is in full force and effect without
modification except as represented by Tenant, and (ii) there are no uncured
defaults in Tenant's performance.

     30. RULES AND REGULATIONS. Tenant shall faithfully observe and comply with
the "Rules and Regulations," a copy of which is attached hereto and marked
Exhibit "F", and all reasonable and nondiscriminatory modifications thereof and
additions thereto from time to time put into effect by Landlord, as long as such
additions and modifications do not materially increase Tenant's obligations
hereunder or materially adversely affect its use or occupancy of the Premises.
Landlord shall not be responsible to Tenant for the violation or non-performance
by any other tenant or occupant of the Building of any of said Rules and
Regulations.

     31. CONFLICT OF LAWS. This Lease shall be governed by and construed
pursuant to the laws of the State of California.

     32. SUCCESSORS AND ASSIGNS. Except as otherwise provided in this Lease, all
of the covenants, conditions and provisions of this Lease shall be binding upon
and shall inure to the benefit of the parties hereto and their respective heirs,
personal representatives, successors and assigns.

     33. SURRENDER OF PREMISES. The voluntary or other surrender of this Lease
by Tenant, or a mutual cancellation thereof, shall not work a merger, and shall,
at the option of     

                                     -55-
<PAGE>
 
    
Landlord, operate as an assignment to it of any or all subleases or
subtenancies. Upon the expiration or termination of this Lease, Tenant shall
peaceably surrender the Premises and all alterations and additions thereto,
broom clean the Premises, leave the Premises in good order, repair and
condition, free from any and all Hazardous Materials, reasonable wear and tear
excepted, and comply with the provisions of Paragraph 15. The delivery of keys
to any employee of Landlord or to Landlord's agent or any employee thereof shall
not be sufficient to constitute a termination of this Lease or a surrender of
the Premises.

     35. PERFORMANCE BY TENANT. All covenants and agreements to be performed by
Tenant under any of the terms of this Lease shall be performed by Tenant at
Tenant's sole cost and expense and without any abatement of rent. If (i) Tenant
shall, prior to delinquency, fail to pay any sum of money owed to any party
other than Landlord, for which it is liable hereunder, and such failure shall
continue for ten (10) days after notice thereof by Landlord, or (ii) if Tenant
shall fail to perform any other act on its part to be performed hereunder, and
such failure shall continue for thirty (30) days after notice thereof by
Landlord (or such longer reasonable cure period if more than thirty (30) days
are reasonably required for such cure and Tenant commences cure within such
thirty (30) day period and diligently prosecutes such cure to completion),
Landlord may upon notice to Tenant, without waiving or releasing Tenant from
obligations of Tenant, but shall not be obligated to, make any such payment or
perform any such other act to be made or performed by Tenant. All sums so paid
by Landlord and all necessary incidental costs together with interest thereon at
the maximum rate permissible by law, from the date of such payment by Landlord,
shall be payable to Landlord on demand. Tenant covenants to pay any such sums,
and Landlord shall have (in addition to any other right or remedy of Landlord)
all rights and remedies in the event of the non-payment thereof by Tenant as
are set forth in Paragraph 25.     

                                     -56-
<PAGE>
 
    
     38. WAIVER. The waiver by either party of any breach of any term, covenant
or condition herein contained shall not be deemed to be a waiver of any
subsequent breach of the same or any other term, covenant or condition herein
contained, nor shall any custom or practice which may grow up 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 the performance by the
other party in strict accordance with said terms. The subsequent acceptance of
rent hereunder by Landlord shall 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 shall be deemed to be other than on
account of the earliest installment of such rent or other amount due, nor shall
any endorsement or statement on any check or any letter accompanying any check
be deemed an accord and satisfaction, and     

                                      -57-
<PAGE>
 
    
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.

     39. IDENTIFICATION OF TENANT. If more than one person executes this Lease
as Tenant, (a) each of them is jointly and severally liable for the keeping,
observing and performing of all of the terms, covenants, conditions, provisions
and agreements of this Lease to be kept, observed and performed by Tenant, and
(b) the term "Tenant" as used in this Lease shall mean and include each of them
jointly and severally. The act of or notice from, or notice or refund to, or the
signature of any one or more of them, with respect to the tenancy of this Lease,
including, but not limited to, any renewal, extension, expiration, termination
or modification of this Lease, shall be binding upon each and all of the persons
executing this Lease as Tenant with the same force and effect as if each and all
of them had so acted or so given or received such notice or refund or so signed.

     40. PARKING. Tenant's parking rights and obligations shall be subject to
the following terms and conditions:

          (a) Visitor Parking. So long as this Lease is in effect, Tenant's
     visitors and guests shall be entitled to use those specific parking areas
     which are designated for short term visitor parking and which are located
     within the surface parking area(s), if any, and/or within the parking
     structure(s) which serve the Building. Visitor parking shall be made
     available at a charge to all visitors and guests, with the rate being
     established by Landlord in its discretion from time to time. Tenant, at its
     sole cost and expense, may elect to validate such parking for its visitors
     and guests. All such visitor parking shall be on a non-exclusive, in-
     common basis with all other visitors and guests of the Development.
     Notwithstanding any contrary provision of this Lease, in the event that the
     number of Tenant's visitors utilizing the Parking Facilities consistently
     exceeds fifty (50) visitors per day, Landlord shall have the right from
     time to time to reduce Tenant's maximum number of unreserved monthly
     parking privileges to accommodate such excessive visitor usage.

          (b) Unreserved Employee Parking. So long as this Lease is in effect,
     Landlord hereby agrees to lease to Tenant up to _______________ unreserved
     employee parking privileges; provided, however, that Tenant stall at all
     tines be obligated to lease a minimum of ________________ of such
     unreserved employee parking privileges (the "Minimum Parking Requirement");
     provided, however, the Minimum Parking Requirement shall be subject to
     reduction to reflect governmentally mandated reductions in the number of
     vehicles     

                                     -58-
<PAGE>
 
   
     which Tenant and its employees are permitted to utilize for access to the
     Premises. Tenant shall notify Landlord from time to time of the exact
     number of unreserved privileges which Tenant desires to lease. Subject to
     the rental abatement provisions set forth in Paragraph 5(c) above, as
     consideration for the use of such unreserved employee parking privileges
     Tenant shall pay to Landlord during the initial Term of the Lease, as
     additional rent under the Lease, _____________________ per month for each
     such unreserved employee parking privilege. Tenant shall pay Landlord the
     additional rent for such unreserved employee parking privileges monthly,
     concurrently with each monthly payment of Monthly Basic Rent. All
     unreserved employee parking spaces shall be made available to Tenant, its
     employees and all other tenants and employees of the Development entitled
     to use such parking facilities, on a non-exclusive, in-common basis.

          (c) Reserved Parking. So long as this Lease is in effect, Landlord
     here leases to Tenant and Tenant hereby lease from Landlord _____________
     reserved parking spaces. Subject to the rental abatement provisions set
     forth in Paragraph 5(c) above, as consideration for the use of such
     reserved parking spaces Tenant shall pay to Landlord the additional rent
     under the Lease. Tenant shall pay Landlord the additional rent for such
     reserved parking spaces monthly, concurrently with each monthly payment of
     Monthly Basic Rent.
                                                                          
          (d) Use of Unreserved and Reserved Parking Spaces. With respect to
     reserved parking, Tenant shall use only the parking space(s) specifically
     designated by Landlord for use by Tenant. With respect to unreserved
     employee parking, Tenant shall not use any 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. Tenant shall be
     obligated to lease the reserved and unreserved parking spaces specified
     herein throughout the Term of the Lease and shall not be entitled to any
     additional reserved or unreserved parking privileges applicable to the
     Premises for the remainder of the Term of the Lease; provided, however, if
     at any tine Tenant desires to increase or reduce the number of reserved or
     unreserved parking spaces it leases under the terms of this Lease, Tenant
     shall notify Landlord in writing of such desire and Landlord shall have the
     right, in its sole and     

                                     -59-
<PAGE>
 
    
     absolute discretion, to either (a) approve such requested increase in the
     number of parking spaces allocated to Tenant (with an appropriate increase
     to the additional rent payable by Tenant for such additional spaces based
     on the then prevailing parking rates), (b) approve such requested decrease
     in the number of parking spaces allocated to Tenant (with an appropriate,
     reduction in the additional rent payable by Tenant to Landlord for such
     eliminated parking spaces based on the then prevailing parking rates), or
     (c) disapprove such requested increase or decrease in the number of parking
     spaces leased to Tenant. Promptly following receipt of Tenant's written
     request, Landlord shall provide Tenant with written notice of its decision
     including a statement of any adjustments to the additional rent payable by
     Landlord to Tenant for parking under the Lease, if applicable.

          (e) General Provisions. Except as otherwise set forth in this
     Paragraph 40, Landlord reserves the right to set and increase monthly fees
     and/or daily and hourly rates for parking privileges from time to time
     during the Term of the Lease. 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. Failure to pay for the lease of any
     particular parking spaces may be treated by Landlord as a failure to pay
     rent as required under the Lease, and, in addition to all other remedies
     available to Landlord under the Lease, at law or in equity, Landlord may
     elect to recapture such parking spaces for the balance of the Term of this
     Lease if Tenant does not cure such failure to pay within the applicable
     cure period set forth in the Default section of this Lease. Tenant's
     parking rights and privileges described herein are personal to Tenant and
     may not be assigned or otherwise transferred, or otherwise conveyed,
     without Landlord's prior written consent, which consent Landlord may
     withhold in its sole and absolute discretion. In any event, under no
     circumstances may Tenant's parking rights and privileges be transferred,
     assigned or otherwise conveyed separate and apart from Tenant's interest in
     the Lease. The use by Tenant, its employees and invitees of the parking
     described herein shall be subject to the terms and conditions of the
     Parking Rules and Regulations set forth in Exhibit "F" attached to the
     Lease and by this reference incorporated herein. Notwithstanding any
     contrary provision of this Lease, in the event necessitated by damage or
     destruction, condemnation, or governmental authority. Landlord reserves the
     right to change the location of the Parking Facilities and/or the location
     of Tenant's parking privileges therein to another location in the
     Development with reasonable access to, and within a reasonable walking     

                                     -60-

     distance from, the Building (or on a temporary basis during any reasonable
     period of repair or restoration, to a location served by a shuttle), as
     long as such change is applied on a nondiscriminatory basis to Tenant in
     relation to the other tenants in the Building. In the event that such
     parking relocation is permanent, Tenant's parking charges shall be subject
     to an equitable reduction in the event that the quality and/or location of
     Tenant's new parking facilities are not commensurate with the Parking
     Facilities.

     41. FORCE MAJEURE. Neither party shall have any liability whatsoever to the
other party on account of (a) the inability to fulfill, or delay in fulfilling,
any obligations under this Lease by reason of strike, other labor trouble,
governmental preemption or priorities or other controls in connection with a
national or other public emergency, or shortages of fuel, supplies or labor
resulting therefrom, or any other cause, whether similar or dissimilar to the
above, beyond the reasonable control of the performing party; or (b) any failure
or defect in the supply, quantity or character of electricity or water furnished
to the Premises, by reason of any requirement, act or omission of the public
utility or others furnishing the Building with electricity or water, or for any
other reason, whether similar or dissimilar to the above, beyond the performing
party's reasonable control. If this Lease specifies a time period for
performance of an obligation, that time period shall be extended by the period
of any delay in such performance caused by any of the events of force majeure
described above. Notwithstanding any contrary provision of this Paragraph 41,
the provisions of this Paragraph 41 shall not be applicable to the monetary
obligations of either party hereunder.

     42. TERMS AND HEADINGS. The words "Landlord" and "Tenant" as used herein
shall include the plural as well as the singular. Words used in any gender
include other genders. The paragraph headings of this Lease are not a part of
this Lease and shall have no effect upon the construction or interpretation of
any part hereof.

     43. EXAMINATION OF LEASE. Submission of this instrument for examination or
signature by Tenant does not constitute a reservation of or option for lease,
and it is not effective as a lease or otherwise until execution by and delivery
to both Landlord and Tenant.

     44. TIME. Time is of the essence with respect to the performance of every
provision of this Lease in which time of performance is a factor.

     45. PRIOR AGREEMENT; AMENDMENTS. This Lease contains all of the agreements
of the parties hereto with respect to any matter covered or mentioned in this
Lease, and no prior agreement     

                                     -61-
<PAGE>
 
    
or understanding pertaining to any such matter shall be effective for any
purpose. No provisions of this Lease may be amended or added to except by an
agreement in writing signed by the parties hereto or their respective
successors-in-interest.

     46. SEPARABILITY. Any provision of this Lease which shall prove to be
invalid, void or illegal in no way affects, impairs or invalidates any other
provision hereof, and such other provisions shall remain in full force and
effect.

short form memorandum thereof without the consent of the other.

     48. LIMITATION ON LIABILITY. In consideration of the benefits accruing
hereunder, Tenant and all successors and assigns covenant and agree that, in the
event of any actual or alleged failure, breach or default hereunder by Landlord:

     49. MODIFICATION FOR LENDER. If, in connection with obtaining construction,
interim or permanent financing for the Building the lender shall request
reasonable modifications in this Lease as a condition to such financing, Tenant
will not unreasonably withhold, delay or defer its consent thereto, provided
that such modifications do not increase the obligations of Tenant hereunder or
materially adversely affect the leasehold interest hereby created or Tenant's
rights hereunder.

     50. FINANCIAL STATEMENTS. At any time during the Term of this Lease, Tenant
shall upon ten (10) days prior written notice from Landlord not more often than
twice in any calendar year, provide Landlord with a current financial statement
and financial statements of the two (2) years prior to the current financial
statement year for Tenant. Such statement shall be prepared in accordance with
generally accepted accounting principles and, if such is the normal practice of
Tenant, shall be audited by an independent certified public accountant.

     51. QUIET ENJOYMENT. Landlord covenants and agrees with Tenant that upon
Tenant paying the rent required under this Lease and paying all other charges
and performing all of the covenants and provisions aforesaid on Tenant's part to
be observed and performed under this Lease, Tenant shall and may peaceably and
quietly have, hold and enjoy the Premises in accordance with this Lease. 

     52. TENANT AS CORPORATION OR PARTNERSHIP. If Tenant executes this Lease as
a corporation or partnership, then Tenant and the persons executing this Lease
on behalf of Tenant represent and warrant that such entity is duly qualified to
do business in California and that the individuals executing this Lease on
Tenant's behalf are duly authorized to execute and deliver this Lease on its
behalf, in the case of a corporation, in accordance with a duly adopted
resolution of the board of directors of Tenant, a copy of which is to be
delivered to Landlord on execution hereof, and in accordance with the by-laws of
Tenant, and in the case of a partnership, in accordance with the partnership
agreement and the most current amendments thereto, if any, copies of which are
to be delivered to Landlord on execution hereof, and that this Lease is binding
upon Tenant in accordance with its terms.

     61. ACCESS TO PREMISES. Tenant shall have access to the Premises
twenty-four (24) hours per day, seven (7) days per week, fifty-two (52) weeks
per year (after-hours access to be in compliance with reasonable security
procedures established by Landlord).

     62. SIGNAGE. Tenant shall be entitled to an eyebrow identity sign on the
exterior face of the Building. Such exterior sign shall identify only the
original Tenant or an     

                                     -75-
<PAGE>
 
    
Affiliate Subtenant. The exact location, size, materials, graphics and lighting
(if any) with respect to such signage shall be consistent and compatible with
any covenants, conditions and restrictions affecting the Building and/or
Development, all applicable laws, regulations and ordinances of the City of
Irvine or any other applicable governmental body, and the sign criteria for the
Development, and shall also be subject to Landlord's reasonable approval. As
soon as reasonably possible after the execution of this Lease, Landlord shall
notify Tenant in writing of the alternative locations for Tenant's signage on
the exterior face of the Building. During the thirty (30) day period following
Landlord's notice Tenant shall have the right to select which of such
alternative signage locations Tenant desires to utilize. Prior to the earlier of
Tenant's selection of its signage location or the end of such thirty (30) day
period, Landlord shall not offer any other non-retail tenant in the Building
exterior signage rights at a specific location without Tenant's prior written
consent. In addition, without the prior written consent of Tenant, during any
period during which Tenant retains its exterior signage rights described in this
Paragraph 62, Landlord shall not hereafter permit another non-retail tenant in
the Building to install signage (excluding existing Wells Fargo signage) on the
exterior face of the Building other than at those alternative signage locations
offered to Tenant which Tenant did not select for the location of its sign.
Landlord shall be responsible for the costs associated with the initial
installation of such exterior signage. Tenant shall be responsible for all
maintenance and utility costs with respect to such exterior sign. At the
termination of this Lease or at any other time when Tenant no longer is entitled
to its signage hereunder, Landlord shall have the right, but not the obligation,
at Landlord's sole cost and expense, to remove such exterior sign.
Notwithstanding any contrary provision of this Paragraph 62, Tenant's exterior
signage rights granted herein shall cease and be of no further force or effect
if at any time during the Term the original Tenant and Affiliate Subtenants fail
to physically occupy at least fifty percent (50%) of the rentable area of the
Premises. Tenant shall, at Tenant's sole cost and expense, be permitted to
install appropriate signage on the walls of the elevator lobbies of the four
floors of the Building under lease by Tenant, and on the entrance doors to its
Premises. The exact location, size, materials, graphics and lighting (if any)
with respect to such interior signage shall be subject to Landlord's reasonable
approval. At the termination of this Lease, Tenant shall be responsible for the
cost of removal of all such interior signage and the cost of repairing any
damage to the Building caused by such removal. Except as otherwise provided in
this Paragraph 62 or as provided in Paragraph 4 of Exhibit "F" regarding the
Building directory, Tenant shall have no right to install or maintain Tenant
identification signs in any other location in, on or about the Premises or the
Development and     

                                     -76-
<PAGE>
 
    
shall not display or erect any other signs, displays or other advertising
materials that are visible from the exterior of the Building. The signage rights
granted to Tenant pursuant to this Paragraph 62 shall be personal to the
original Tenant and Affiliate Subtenants and may not be exercised or be
assigned, voluntarily or involuntarily, by or to any entity other than the
original Tenant or an Affiliate Subtenant.

     63. [Intentionally Omitted.]

     64. ABATEMENT OF RENT WHEN TENANT IS PREVENTED FROM USING PREMISES. In the
event that Tenant is prevented from using and does not use the Premises or any
portion thereof, for five (5) consecutive business days ("Eligibility Period"),
as a result of any damage or destruction (subject to the provisions of Paragraph
23) to the Premises or Building, any failure of Landlord to provide services,
utilities or access to the Premises, any failure of Landlord to provide access
to the parking described in this Lease or any Landlord repairs or other
construction work preventing Tenant's access to or use of the Premises, then
Tenant's Basic Rent, parking charges, and Operating Expense escalation charges
shall be abated or reduced, as the case may be, during the period during which
Tenant continues to be so prevented from using the Premises, or a portion
thereof, in the proportion that the rentable area of the portion of the Premises
that Tenant is prevented from using, and does not use, bears to the total
rentable area of the Premises. However, in the event that Tenant is prevented
from conducting, and does not conduct its business in any portion of the
Premises for a period of time exceeding the Eligibility Period, and the
remaining portion of the Premises is not sufficient to allow Tenant to conduct
its business therein, and if Tenant does not conduct its business from such
remaining portion, then during the period during which Tenant is so prevented
from conducting its business therein, the Rent (including parking charges, and
Operating Expenses escalation charges) for the entire Premises shall be abated;
provided, however, if Tenant reoccupies and conducts its business from any
portion of the Premises during such period, the rent allocable to such
reoccupied portion, based on the proportion that the rentable area of such
reoccupied portion bears to the total rentable area of the Premises, shall be
payable by Tenant from the date such business operations commence.

2.1.  Credit Line.  Subject to the terms and conditions set forth in this
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.

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

interest.

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
<PAGE>
 
request, the insurance certificates with respect to such insurance. In addition,

maintain, at its sole expense, the Collateral insured for an amount not less
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.

7.9. Taxes.  Customer agrees to pay, when due, all taxes lawfully levied
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
Effect.

Law applicable to the Collateral or any part thereof, or to the operation of its
business.

7.11. Fiscal Year.  Customer agrees to maintain its fiscal year as a year

properties (business and otherwise) in good condition and

                                 Page 33 of 46

from other property of Customer, holding the same in trust for IBM Credit until

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
matters and things necessary or expedient to be observed or performed under or

operate the Collateral and carry on and conduct its business in a proper and

any expense to Customer.

7.15. Subsidiaries. IBM Credit may require that any Subsidiaries of Customer
become parties to this Agreement or any other agreement executed in connection

involuntary) and there shall result from such "reportable event" or termination
proceedings a liability of Customer to the PBGC which in the reasonable opinion
of IBM Credit will have a Material Adverse Effect;

    
   (P)  Any "person" (as defined in Section 13(d)(3) of the Securities
Exchange Act of {1934}, as amended) acquires a beneficial interest in 50% or
more of the Voting Stock of Customer.

Default which has not been waived in writing by IBM Credit, IBM Credit may, in
it sole discretion, take any or all of the following actions, without prejudice
to any other rights it may have at law or under this Agreement to enforce its
claims against the Customer: (a) declare its Obligations to be immediately due
and payable (except with

                                 Page 39 of 46
<PAGE>
 
respect to any Event of Default set forth in Section 9.1(E) hereof, in which
case all Obligations shall automatically become immediately due and payable
without the necessity of any notice or other demand) without presentment,
demand, protest or any other action or obligation of IBM Credit; and

(b)  immediately terminate the Credit Line hereunder.

9.3.  Remedies.  (A)  Upon the occurrence and during the continuance of any
Event of Default which has not been waived in writing by IBM Credit, IBM Credit
may exercise all rights and remedies of a secured party under the U.C.C. Without
limiting the generality of the foregoing, IBM Credit may: (i) remove from any
premises where same may be located any and all documents, instruments, files and
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
Agreement is terminated, all of Customer's Obligations shall be immediately due
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 17 of 23

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     

                                 Page 18 of 23

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

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

force and effect as of the date of Tenant's possession of the premises.

Tenant accepts premises in their present condition. Landlord agrees to complete

early occupancy may cause some delay in the construction of the tenant

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

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

2.   PREMISES AND COMMON AREAS.
    
(a)  PREMISES. Landlord hereby leases to Tenant and Tenant hereby leases from
Landlord the Premises upon and subject to the terms, covenants and conditions
contained in this Lease to be performed by each party.

Commencement Date, Tenant agrees to pay Landlord as additional rent in
accordance with the terms of this Paragraph 6, Tenant's Share of Operating

<PAGE>
 
    
(xiii) amortization on a straight line basis over the useful life [together with
interest at the Interest Rate on the unamortized balance] of all capitalized
expenditures which are: (A) reasonably intended to produce a reduction in

costs and expenses of repairs, resurfacing, repairing, maintenance, painting,

appropriate reserves    

(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.     

8.   USE.

(a)  TENANT'S USE OF THE PREMISES. The Premises may be used for the use or uses
set forth in Subparagraph 1(1) only, and Tenant will not use or permit the
Premises to be used for any other purpose without the prior written consent of

Lease will be deemed to give Tenant any exclusive right to such use in the
Project.

or permit any nuisance or waste in, on, under or about the Premises or elsewhere

Landlord an Environmental Questionnaire in the form of Exhibit "G" attached

Landlord of any release of Hazardous Materials in the Premises, the Building or
any other portion of the Project which Tenant becomes aware of during the Term
of this Lease, whether caused by Tenant or any other persons or entities. In the
event of any release of Hazardous Materials caused or permitted by Tenant or any
of Tenant's Parties, Landlord shall have the right, but not the obligation, to
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
enter upon the Premises to inspect, investigate, sample and/or monitor the
Premises to determine if Tenant is in compliance with the terms of this Lease
regarding Hazardous Materials. As used in this Lease, the term "Hazardous
Materials" shall mean and include any hazardous or toxic materials, substances

formaldehyde foam insulation, polychlorinated biphenyls ("PCBs"), and freon and
other chlorofluorocarbons. The provisions of this Subparagraph 8(c) will survive

other refuse on the Premises except in sanitary containers and agrees to
regularly and frequently remove same from the Premises. Tenant shall keep all

third party broker with regards to any renewals and/or expansions unless such
renewal or expansion rights are included within this Lease at the time of
execution by the parties and in Landlord's commission agreement with the
broker(s) specified in Subparagraph 1(m).     

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
or subtenancies. Upon The expiration or earlier termination of this Lease,
Tenant agrees to peaceably surrender the Premises to Landlord broom clean and in
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
from the Premises to the extent required under Paragraph 13 and all damage
caused by such removal repaired as required by Paragraph 13. The delivery of
keys to any employee of Landlord or to Landlord's agent or any employee thereof
alone will not be sufficient to constitute a termination of this Lease or a
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
at sufferance only, and evict Tenant immediately, or consent in writing to the
continued occupancy by Tenant which shall be subject to all of the terms,
covenants and conditions of this Lease, so far as applicable, including the
payment of Operating Expenses, except that the Monthly Base Rent for any month
or partial month during which Tenant holds over shall be equal to one hundred
fifty percent     

                                       9
<PAGE>
 
    
(150%) of the Monthly Base Rent in effect under this Lease immediately prior to
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
any succeeding tenant founded on or resulting from Tenant's failure to surrender
the Premises. The provisions of this Subparagraph 11(b) will survive the
expiration or earlier termination of this Lease.     

12.  TAXES ON TENANT'S PROPERTY. Tenant agrees to pay before delinquency, all
taxes and assessments (real and personal) levied against Tenant's business
operations or any personal property, improvements, alterations, trade fixtures
or merchandise placed by Tenant in or about the Premises
    
13.  ALTERATIONS. Tenant shall not make any alterations to the Premises or any
other aspect of the Project, without Landlord's prior written consent, which
consent Landlord may withhold in its reasonable but subjective discretion. All
permitted alterations must be performed in compliance with Landlord's standard
rules and regulations regarding alterations. All alterations will become the
property of Landlord and will remain upon and be surrendered with the Premises
at the end of the Term of this Lease; provided, however, Landlord may require
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
shall be liable for all costs of disposition of Tenant's abandoned property and
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
and/or sale of such items), with any remainder to be paid to Tenant.     

14.  REPAIRS.
    
(a)  LANDLORD'S OBLIGATIONS. Landlord agrees to repair and maintain the
structural portions of the Building, including the foundations, bearing and
exterior walls (excluding glass),     

                                       10

subflooring and roof (excluding skylights), and the unexposed electrical,
plumbing and sewer systems, including those portions of such systems which are
outside the Premises, gutters and downspouts on the Building and the heating,
ventilating and air conditioning systems which serve the Premises, unless such

omission of any duty by Tenant, its agents, servants, employees or invitees, in
which case Tenant will pay to Landlord, as additional rent, the reasonable cost
of such maintenance and repairs. The costs of maintenance and repairs performed
by Landlord will be included in Operating Expenses. Except as provided in this
Subparagraph 14(a), Landlord has no obligation to alter, remodel, improve,
repair, decorate or paint the Premises or any part thereof. Landlord will not be
liable for any failure to make any such repairs or to perform any maintenance
unless such failure shall persist for an unreasonable time after written notice
of the need of such repairs or maintenance is given to Landlord by Tenant.
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,
without limitation, to the extent the Premises are located in California, the
provisions of California Civil Code Sections 1941 and 1942 and any successor
statutes or laws of a similar nature).     
    
(b)  TENANT'S OBLIGATIONS. Tenant agrees to keep, maintain and preserve the
Premises in a state of condition and repair consistent with the Building and,
when and if needed, at Tenant's sole cost and expense, to make all repairs to
the Premises and every part thereof including, without limitation, all walls,
storefronts, floors, ceilings, interior and exterior doors and windows and
fixtures and interior plumbing. Any such maintenance and repairs will be
performed by Landlord's contractor, or at Landlord's option, by such contractor
or contractors as Tenant may choose from an approved list to be submitted by
Landlord. Tenant agrees to pay all costs and expenses incurred in such
maintenance and repair within seven (7) days after billing by such contractor or
contractors. If Tenant refuses or neglects to repair and maintain the Premises
property as required hereunder to the reasonable satisfaction of Landlord,
Landlord, at any time following ten (10) days from the date on which Landlord
makes a written demand on Tenant to effect such repair and maintenance, may
enter upon the Premises and make such repairs and/or maintenance, and upon
completion thereof, Tenant agrees to pay to Landlord as additional rent,
Landlord's costs for making such repairs plus an amount not to exceed ten
percent (10%) of such costs for overhead, within ten (10) days of receipt from
Landlord of a written itemized bill therefor. Any amounts not reimbursed by
Tenant within such ten (10) day period will bear interest at the interest Rate
until paid by Tenant.     
    
15.  LIENS. Tenant agrees not to permit any mechanic's, materialmen's or other
liens to be filed against all or any part of the Project, the Building or the
Premises, nor against Tenant's leasehold interest in the Premises, by reason of
or in connection with any repairs, alterations, improvements or other work
contracted for or undertaken by Tenant or any other act or omission      

                                       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
and/or materials at the Premises. Landlord will have the right at all reasonable
times to post on the Premises and record any notices o/ non-responsibility which
it deems necessary for protection from such liens. If any such liens are filed,
Tenant will, at its sole cost and expense, promptly cause such liens to be
released of record or bonded so that it no longer affects title to the Project,
the Building or the Premises. If Tenant fails to cause any such liens to be so
released or bonded within ten (10) days after filing thereof, such failure will
be deemed a material breach by Tenant under this Lease without the benefit of
any additional notice or cure period described in Paragraph 22 below, and
Landlord may, without waiving its rights and remedies based on such breach, and
without releasing Tenant from any of its obligations, cause such liens to be
released by any means it shall deem proper, including payment in satisfaction of
the claims giving rise to such liens. Tenant agrees to pay to Landlord within
ten (10) days after receipt of invoice from Landlord, any sum paid by Landlord
to remove such liens, together with interest at the Interest Rate from the date
of such payment by Landlord.     

16.  ENTRY BY LANDLORD.  Landlord and its employees and agents will at all
reasonable times have the right to enter the Premises to inspect the same, to
show the Premises to prospective purchasers or tenants, to post notices of
nonresponsibility, and/or to repair the Premises as permitted or required by
this Lease. In exercising such entry rights, Landlord will endeavor to minimize
as reasonably practicable, the interference with Tenant's business, and will
provide Tenant with reasonable advance notice of any such entry (except in
emergency situations). Landlord will at all times have and retain a key with
which to unlock all doors in the Premises, excluding Tenant's vaults and safes.
Tenant shall not alter any lock or install any new or additional locks or bolts
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
negligence or willful misconduct of Landlord, any entry to the Premises obtained
by Landlord will not be construed or deemed to be a forcible or unlawful entry
into the Premises, or an eviction of Tenant from the Premises and Landlord will
not be unable to Tenant for any damages or losses resulting from any such entry.
    
17.  UTILITIES AND SERVICES. Throughout the Term of this Lease, Tenant shall pay
directly to the utility company providing such service all costs for water, gas,
heat, light, power, sewer, electricity, telephone and other services metered,
chargeable or provided to the Premises. Landlord will not be liable to Tenant
for any failure to furnish any of the foregoing utilities and services if such
failure is caused by all or any of the following:  (i) accident, breakage or
repairs" (ii) strikes, lockouts or other labor disturbance or labor dispute of
any character; (iii) governmental regulation, moratorium or other governmental
action or inaction; (iv) inability despite the exercise of reasonable diligence
to obtain electricity, water or fuel, or (v) any other cause beyond Landlord's
reasonable control. In addition, in the event of any stoppage or interruption of
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

the Project, or caused by quasi-public work, (iii) any damage to 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

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

(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.     

                                       22
<PAGE>
 
    
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
any of the Rules and Regulations.     

                                       23
<PAGE>
 
    
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

<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)
except as may be necessary to secure jurisdiction of the partnership, no partner
of Landlord shall be sued or named as a party in any suit or action and no
service of process shall be made against any partner of Landlord; (c) no partner

constitute personal obligations of the individual partners, directors, officers

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.

any guarantors of Tenant. Such statements are to be prepared in accordance with
generally accepted accounting principles and, if such is the normal practice of
Tenant, audited by an independent certified public accountant.     
    
37.  QUIET ENJOYMENT. Landlord covenants and agrees with Tenant that upon Tenant
paying the rent required under this Lease and paying all other charges and
performing all of the covenants and provisions on Tenant's part to be observed

                          ADDITIONAL LEASE PROVISIONS     
    
17.(a)  UTILITIES AND SERVICES:  The electricity for the Premises is currently
in Landlord's name.  Tenant agrees to contact Southern California Edison at
(800) 990-7788 within ten (10) days from the date Tenant takes possession of the
Premises and have the bill for electricity put into Tenant's name.     
    
Tenant shall reimburse Landlord for any interim charges actually billed to
Landlord for electricity from the date Tenant takes possession of the Premises
until the date the bill is put into Tenant's name.     
    
In the event Tenant fails to put the bill for electricity in Tenant's name
within ten (10) days from the date Tenant takes possession of the Premises,
Landlord shall have the right to contact Southern California Edison on the
eleventh (11th) day after Tenant takes possession of the Premises and have the
electricity for the Premises turned off.     
    
Tenant hereby acknowledges that Tenant has the absolute responsibility to
contact Southern California Edison and have electrical service put into Tenant's
name.  In the event Tenant fails to put the bill for electrical service into
Tenant's name as required hereinabove and Landlord has electrical service turned
off, Tenant understands that there will be no electrical service to the
Premises.  In such event, Tenant releases and holds Landlord harmless from any
claims, demands, liabilities, damages, expenses, actions and causes of action
based on, arising out of, or related thereto.

                                 SIGN CRITERIA
                                 -------------

1.   Recitals:
     -------- 

Signs and other graphics are an essential element of any community.  As such
their location, number, size and design consistency have a significant influence
upon a community's visual environment and a resultant effect upon a viewer's
perception of that community.

In communities where signs have not been property regulated, they have
                                ---                                   
contributed to visual clutter, unpleasant impressions and even confusion.  In
many of these instances signs have failed to achieve their original objective:
                        -----------------------------------------------------  
Communication of their intended message.

Under proper regulation, however, signs and other graphics may be designed and
displayed to effectively communicate their message and at the same time be
appropriate to their surroundings. Signs so designed and displayed can
contribute to community identity and help create a community which is
efficiently organized and visually attractive.  All new leases and renewals will
contain this exhibit and management will strictly enforce its intent.

2.   Criteria:
     --------

Tenant shall be allowed only one sign regardless of size of occupancy.  No
advertising placards, merchandise, banners, pennants, names, insignia,
trademarks, or other descriptive material shall be affixed or maintained in a
fashion to be displayed to the exterior of the suite or on the glass panes of
the building, landscaped areas, streets or parking areas.  No alarm company
stickers larger than 3-1/2" x 2-1/2" will be allowed.  Koll standard U.P.S.
signs are available at the leasing office for the asking.  No other U.P.S.
signage will be permissible.

3.   Signage Layout Submitted to Landlord for Approval:
     ------------------------------------------------- 

A layout of each proposed sign showing copy/logo and color samples must be
submitted to the Landlord for Approval prior to fabrication and installation.

4.   Sign Specification/Method of Building Attachment:
     ------------------------------------------------ 

The subject premises have an 18" x 48" aluminum receptacle/frame provided by and
at the sole expense of the Landlord for insertion and placement of Tenant
signage.  The Tenant's sign/insert shall be constructed at the sole expense of
the Tenant constructed of Opaque Lumisite or second-surface Lumisite coated in
white.  If it is necessary to coat the exterior surface to obtain the desired
background color, the entire surface must be coated the same color with no
masking and the coating must have a five (5) to seven (7) year exterior life
expectancy without fading or peeling.  All lettering legends and logos are to be
computer-cut two (2) mil. high performance vinyl.  Hand painting in not
permitted.

5.   Window Lettering:
     ---------------- 
     
<PAGE>

     
No window lettering is permitted except for the Tenant's business name only
                                                ---------------------------
which may be placed in the window immediately adjacent to the main entry door.
Tenants with little or no adjacent glass may place their name on the door. Copy
is to be computer cut two (2) mil. high performance white vinyl in 3" helvetica
medium lettering. Lettering is to be centered between the window frames with a
minimum 1-1/2" border on each side. Lettering is not to be condensed more than
75%. Letter height may be reduced up to 1/2" to stay within the other criteria.
If the business name still cannot be accommodated on one line, then it may be
placed on two (2) lines using a 2-1/2" letter height and 1-3/4" spacing between
lines. The top edge of the top line is to be 69" above the concrete slab. Any
and all other attachments to the glass will be in non-conformance. Subtenant
names, business services or types, and all other attachments to the glass or
glazing, except as described above, shall be considered non-conforming and
subject to removal.

6.   Window Tinting:
     ---------------

No mirrored or colored tinting will be authorized.  Before any tinting is
applied to the Tenant's windows, a sample must be submitted to the Landlord for
written approval prior to installation.

7.   Landlord's Right to Enforce:
     ----------------------------

This criteria establishes the uniform policies for all Tenant sign
identification.  This criteria has been established for the purpose of
maintaining the over all appearance of the complex and to provide our tenants
with a consistent quality environment from which to conduct business.  Any sign,
graphics or other material installed that does not conform to this criteria may
be brought Into conformity by the Landlord without notice.  Any cost incurred by
the Landlord to remove nonconforming signs or to correct defacement from
mounting of non-conforming signs shall be the responsibility of Tenant.

                            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.

     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

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

     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.

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
retained by the Landlord as security for the Tenant's payment of the Rent and
performance of all of its other obligations under the provisions of this

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.

____________________
    
/11//  Notwithstanding anything contained herein to the contrary provided Tenant
hasn't been in default, Landlord will refund one month of the security deposit
in the amount of eight thousand seven hundred thirty-nine and 83/100 ($8,739.83)

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
where such sign is visible from the exterior of the Premises, unless the
Landlord has given its express, written consent thereto.
    
     3.5  [DELETED]     

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.

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.

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.

             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

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

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-

shall remain the Tenant's property.

SECTION 6. UTILITIES AND SERVICES.

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.

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.    

     10.2 Anything contained in the foregoing provisions of this Section to the
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.

notwithstanding, neither the Tenant nor any other person having an interest in
the possession, use or occupancy of the Premises or any other portion of the
Property shall enter into any lease, sublease, license, concession or other
agreement for the possession, use or occupancy of space in the Premises or any
other portion of the Property which provides for any rental or other payment for
such use, occupancy or utilization based in whole or in part upon the net income
or profits derived by any person from the space in the Premises or other portion
of the Property so leased, used or occupied (other than any amount based on a
fixed percentages of receipts or sales).

     10.3. /20//In the event of any/21// transfer without Landlord's consent,
Landlord may, at its sole option, have the right at any time or from time to
time or from time after such Transfer to terminate this Lease as to all or any
portion of the Premises and enter into a direct lease agreement with the
proposed sublessee. Neither Tenant nor any party claiming an interest under or
through Tenant shall interfere with Landlord's exercise of its rights hereunder.
Tenant hereby indemnifies and holds Landlord harmless from and against any and
all liabilities, costs, losses or damages, including reasonable attorneys fees
and court costs, arising from any breach of the provisions of this section by
Tenant.

SECTION 11. RULES AND REGULATIONS.

     The Landlord shall have the right to prescribe, at its sole discretion,
reasonable rules and regulations (hereinafter referred to as the "Rules and
Regulations") having uniform applicability to all tenants of the Building
(subject to the provisions of their respective leases) and governing their use
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
effect on the date hereof is attached hereto as Exhibit C.

SECTION 12. SUBORDINATION; ATTORNMENT AND NON-DISTURBANCE.

     12.1. SUBORDINATION. This Lease shall be subject and subordinate to the
lien, operation and effect of each mortgage, deed of trust, ground lease and/or
other, similar instrument of encumbrance heretofore or hereafter covering any or
all of the Premises or the remainder of the Property (and each renewal,
modification, consolidation, replacement or extension thereof), (each of which
is herein referred to as a "Mortgage"), all automatically and without the
necessity of any action by either party hereto.

     12.2. ATTORNMENT AND NON-DISTURBANCE. The Tenant shall, promptly at the
request of the

      Tenant,

Landlord or the holder of any Mortgage (herein referred to as a "Mortgagee"),
execute, enseal, acknowledge and deliver such further instrument or instruments

             12.2.1. evidencing such subordination as the Landlord or such
Mortgagee deems necessary or desirable, and

             12.2.2. (at such Mortgagee's request) attorning to such Mortgagee.
Landlord will use reasonable efforts to obtain an agreement from the Mortgagee
(in such Mortgagee's usual form) that such Mortgagee will, in the event of a
foreclosure of any such mortgage or deed of trust (or termination of any such
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
Mortgage to the operation and effect of this Lease without obtaining the
Tenant's consent thereto, by giving the Tenant written notice thereof, in which
event this Lease shall be deemed to be senior to such Mortgage without regard to
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.

SECTION 13. DEFAULT.

     13.1. DEFINITION: As used in the provisions of this Lease, each of the
following events shall constitute, and is hereinafter referred to as, an "Event

             13.1.1. If the Tenant fails to (a) pay any Rent or any other sum
which it is obligated to pay by any provision of this Lease, when and as due and

of competent jurisdiction adjudicating the Tenant a bankrupt or insolvent,
approving a petition seeking such a reorganization, or appointing a receiver,
trustee or liquidator of the Tenant or of all or a substantial part of its
assets, or (b) there otherwise commences as to the Tenant or any of its assets
any proceeding under any bankruptcy, reorganization, arrangement, insolvency,
readjustment, receivership or similar law, and if such order, judgment, decree

            13.1.6./23// [deleted]     

     13.2. NOTICE TO TENANT; GRACE PERIOD. Anything contained in the provisions
of this Section to the contrary notwithstanding, on the occurrence of an Event
of Default the Landlord shall not exercise any right or remedy which it holds
under any provision of this Lease or applicable law unless and until

            13.2.1. the Landlord has given written notice thereof to the Tenant,
if written notice is required by this Section for the Event of Default which has
occurred, and

            13.2.2. the Tenant has failed, (a) if such Event of Default consists
of a failure to pay money, within five (5) days/24//, or (b) if such Event of
Default consists of something other than a failure to pay money, within thirty
(30) days thereafter actively, diligently and in good faith to begin to cure
such Event of Default and to continue thereafter to do so until it is fully
cured; provided, that

            13.2.3. no such notice shall be required, and the Tenant shall be
entitled to no such grace period, (a) in an emergency situation in which the
Landlord acts to cure such Event of Default pursuant to the provisions of
paragraph 13.3.5; or (b) more than twice during any twelve (12) month period, or

/23//  In the event Tenant should cease to continue to operate its business at
the Premises for a period of forty-five (45) consecutive days for any reason
other than Tenant's alterations, casualty or other reason beyond Tenant's
reasonable control, Landlord shall have the right at any time thereafter to
terminate the Lease and recapture the Premises upon thirty (30) days prior
written notice to Tenant. Landlord shall also have the option to recapture the
Premises upon thirty (30) days prior written notice to Tenant without
terminating the Lease. In such event, Tenant shall remain liable for the Rent
until such time as Landlord leases the Premises to another party.

obligated to provide written notice to Tenant twice in each Lease Year;
thereafter, no notice shall be due from Landlord to Tenant and Tenant shall be
in default if it fails to pay such amounts when due.

or all of the following actions:     

            13.3.1. re-enter and repossess the Premises and any and all
improvements thereon and additions thereto;

            13.3.2. declare the entire balance of the Rent for the remainder of
the Term to be due and payable, and collect such balance in any manner not
inconsistent with applicable law;

            13.3.3. terminate this Lease;
    
            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
provided in paragraph 13.2.3), in which event the Tenant shall reimburse the
Landlord for all expenses incurred by the Landlord in doing so, plus interest
thereon at the lesser of the rate of/26// per annum or the highest rate then
permitted on account thereof by applicable law, which expenses and interest
shall be Additional Rent and shall be payable by the Tenant immediately on
demand therefor by the Landlord; and/or     

            13.3.6. pursue any combination of such remedies and/or any other
remedy available to the Landlord on account of such Event of Default under
applicable law.

     13.4. NO WAIVER. No action taken by the Landlord under the provisions of
this Section shall operate as a waiver of any right which the Landlord would
otherwise have against the Tenant for the Rent hereby reserved or otherwise, and
the Tenant shall remain responsible to the Landlord for any loss and/or damage
suffered by the Landlord by reason of any Event of Default.

     13.5. DEFAULT BY LANDLORD. In the event of any default by Landlord,
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-
<PAGE>
 
(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
writing, and (b) deemed to have been given (i) forty-eight (48) hours after
being sent as certified or registered mail in the United States mails, postage
prepaid, return receipt requested, upon its hand delivery to such party,

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,

     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

     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

     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.

                              AGREEMENT OF LEASE
                                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 and clear of such right and 
such right shall be deemed terminated in all respects. Once Landlord has made 
the offer to Tenant to lease any Offer Space during the Term, whether or not 
Tenant leases such space, this right of first offer shall automatically 
terminate in all respects and Tenant shall have no further rights of first offer
with respect to any other Offer Space.

3.   Parking: Tenant shall have the right to use up to forty (40) parking spaces
on the surface lot adjacent to the Building. As the Tenant occupies additional 
space in the Building, Tenant shall have the right to park additional 
automobiles on the building lot based on the same ratio and terms as under the 
initial lease agreement.

4.   Signage: Landlord, at Landlord's sole cost and expense, shall install
Tenant's name on Tenant's entrance to the Premises. Landlord at Landlord's sole
cost and expense, shall have the right to install a building standard sign
bearing the Tenant name and logo on the facade of the Building facing Martin
Luther King, Jr. Highway. The exact location, design and method of installation
of the sign shall be approved by the Landlord and completed in accordance with
all necessary jurisdictional regulations.

5.   Designation of Agent. Landlord's resident agent for the purpose of service
of process, notice, order, or demand required or permitted by law to be served
upon Landlord and the agent's office address is R. Harvey Chappell, Jr., 1200
Mutual Building, Richmond, Virginia 23219.

C.3  ACTIVATION OF JOB ORDER

     (a)  PRICED JOB ORDER

     The following procedure will be followed to initiate work under this
Agreement:

          (1) An oral and/or letter request shall be sent to the Contractor
setting forth the detailed requirements to be accomplished, together with the
necessary attachments (drawings, SOW, PD, DISTRICT DIRECTOR 1423, DISTRICT
DIRECTOR 254, and other applicable documents).

          (2) The Contractor shall immediately acknowledge the request for a

letter is received, by initiating an acknowledgment of the oral request.

          (3) (i)  The Contractor shall review the requirements of the proposed
job order and submit to the Contracting Officer, within the time allotted
(expedited reply is required), a technical proposal and a cost proposal to
complete the requirements.

not in accordance with the terms of this agreement. The Contractor may, however,
request a differing term from the agreement.

          (4) The government shall review and, when applicable, negotiate
estimated cost and fee or profit and the technical requirements.

          (5) Each Job Order shall be fully negotiated prior to the issuance of
the Standard Form 26 to reflect the Government and Contractor agreement of the
technical requirements and consideration.

     (b)  UNPRICED JOB ORDERS

          (1) In an emergency where it is imperative that the designated task be
commenced prior to the execution of a priced job order, the following procedures
will apply. The procedures in Section C.3 (a) in paragraphs (1) (2) and (3) will
be followed for initiating the job order.  Then:

              (i)  After receipt and review of the Contractor's proposal, the
Contracting officer may issue an unpriced job order stating a monetary ceiling
amount for the Job Order and containing a NOT-TO-EXCEED funding limitation
pending documentation of the Job Order.  This Job Order will be on a Form DD1155
"Order for supplies or Services" and will contain a limitation of Government
Liability clause as stated in Section G, Paragraph G.5.  The Contractor is
required to sign the Job Order (DD1155) as acceptance of the ceiling priced job
<PAGE>
 
order or provide a letter containing the proposed ceiling price and stating
agreement to accepting a job order on this basis.  In exceptional cases, where
award must be made prior to receipt of a qualifying technical proposal, the
Government and the Contractor shall negotiate a maximum ceiling price which must
be confirmed in writing.  Use of this procedure will limit the Contractor
expenditures to 50% of the proposed Ceiling price until a qualifying proposal is
received or negotiations have been completed.  In no event shall an entire job
order be priced retroactively.

          (ii) The initial cost proposal you submit to satisfy the Government's
requirement may be the amount specified for the NOT-TO-EXCEED ceiling amount of
an unpriced job order. This establishment of a not-to-exceed price ceiling is in
accordance with DFARS 217.7404-2. To comply with this, your proposal submitted
in response to the Government's request should have a validity period that
allows time for definitization of the job order. This time period could extend
as long as six months depending on the length and complexity of the audit and
other issues.

     (2)  When an unpriced job order is issued on a DD1155, the job order will
contain wording referencing the above BOA provision as well as a limitation on
the amount of funds that may be expended prior to definitization.  The unpriced
job order may incorporate your cost proposal by reference.

     (3)  When definitizing the unpriced job order, the ceiling amount will be
subject to a downward negotiation only.

     (4)  Per the DFAR:  Allowable Profit.  The head of an agency or a designee
shall ensure that the profit allowed on a UCA, for which the final price is
negotiated after a substantial portion of the performance required is completed,
reflects:

          (i)  any reduced cost risk of the contractor with respect to costs
incurred during the performance of the contract before the final price is
negotiated; and

          (ii) the reduced cost risk of the contractor with respect to costs
incurred during performance of the remaining portion of the contract.

     (5)  The Contractor shall submit a proposal not later than ons month after
the date of the ceiling priced job order award.  Negotiations, per the FAR,
shall be completed not later than six months after the date of award of the
ceiling priced job order.  Within these parameters, the Contracting Officer
shall state in the Job Order the actual definitization schedule in accordance
with FAR 52.216-25 Contract Definitization.

any proposed tax assessments, exemptions, exclusions, or refunds which could

tax, it is the contractor's responsibility to identify such exemption under the
applicable statute and to resolve the applicability of such with state or local
taxing authorities.

out any contract, including any contract awarded as a result of a broad agency
announcement (BAA), with a foreign government, or firm if the contract provides
for the conduct of RDT&E in connection with the BMD. Foreign governments and
firms, however, are encouraged to submit offers since this provision is not
intended to restrict BMD access to unique foreign expertise when contract
performance requires a level of competency unavailable in the United States.

     (d)  The prohibition does not apply to a foreign government or firm if:

          (l)  The contract is to be performed within the United States or

          (2)  The contract is exclusively for RDTE in connection with
antitactical ballistic missile systems.

          (3)  The foreign government or firm agrees to share a substantial
portion of the total contract cost.  The foreign share may be considered
substantial where it is equitable with respect to the relative benefits to be
derived from the contract by the U.S. and the foreign parties. For example, if
the contract is more beneficial to the foreign party, its share of the costs
should be correspondingly higher; or

          (4)  The U.S. Government determines that the contract cannot be
competently performed by a United States firm at a price equal to or less than
the price at which the RDTE can be performed by a foreign government or firm.

SUBSTANCES (AUG 1993)

     Section 326 of the FY-93 Defense Authorization Act places restrictions on
the award and modification of contracts requiring the use of Class I - Ozone-
depleting substances (ODS).  Class I ODS are identified in Section 602(a) of the
Clean Air Act (42 U.S.C. Section 7671(a)) and Title 40, Code of Federal
Regulations Section 82, Appendix A.

     DOD has identified hundreds of military specifications that require Class I
ODS. Of these, MPO research indicates that MIL-STD 454, MIL-T 2000, and MIL-T
11268 are of particular applicability to some MPO contracts, although others may
also apply.

     If any of these specifications are included in this acquisition, or if the
contractor knows of any other Class I ODS required, directly or indirectly, at
any level of contract performance, the contractor should notify the MPO
Contracting officer immediately. A subsequent assessment will be conducted by
the Government in an attempt to identify economically feasible substitute
substances or alternative technology.

acceptable plan will be incorporated into the contract, as a material part
thereof

S-6. ACCEPTANCE
     ----------

     (a)  During the Software Acceptance Period, Bank may perform whatever
acceptance tests on the Software it may wish to confirm that the Software is
Operative. For purposes of this Section, the Software shall be deemed Operative
if it does not contain any Class 1 or Class 2 Errors. If Bank discovers during
the Software Acceptance Period that any Software is not Operative, Bank shall
notify Supplier of the deficiencies. Supplier, at its own expense, shall modify,
repair, adjust or replace the Software to make it Operative within 15 days after
the date of Bank's deficiency notice. Bank may perform additional acceptance
tests during a period commencing when Supplier has delivered revised Software
correcting all the deficiencies Bank has noted. This restarted Software
Acceptance Period shall have a duration equal to that of the initial Software
Acceptance Period. If the Software, at the end of the Software Acceptance
Period, still is not Operative in Bank's judgment after consultation with
Supplier, Bank may reject the Software and terminate this Agreement or, at its
option, repeat the procedure in this paragraph as often as it determines is
necessary. If Bank does not notify Supplier of acceptance or rejection of the
Software, it shall be deemed accepted at the end of the Software Acceptance
Period as extended pursuant to this paragraph.

     (b)  Bank shall also use the procedure in this Section to determine
acceptance of Customizations and Update Releases. If Bank finds an Update
Release not to be Operative and rejects it, Bank shall have no obligation to pay
for such Update Release, and Supplier shall continue to support the version or
release of the Software that Bank has installed for at least six months after
any such rejection.

     (c)  During the Equipment Acceptance Period, Bank may perform whatever
acceptance tests on the Equipment it may wish to confirm that the Equipment is
Operative. For purposes of this Section, the Equipment shall be deemed Operative
if it does not contain any Class 1 or Class 2 Errors. If Bank discovers during
the Equipment Acceptance Period that any Equipment is not Operative, Bank shall
notify Supplier of the deficiencies. Supplier, at its own expense, shall modify,
repair, adjust or replace the Equipment to make it Operative within 15 days
after the date of Bank's deficiency notice. Bank may perform additional
acceptance tests during a period commencing when Supplier has delivered revised
Equipment correcting all the deficiencies Bank has noted. This restarted
Equipment Acceptance Period shall have a duration equal to that of the initial
Equipment Acceptance Period. If the Equipment, at the end of the Equipment
Acceptance Period, still is not Operative in Bank's judgment after consultation
with Supplier, Bank may reject the Equipment and terminate this Agreement or, at
its option, repeat the procedure in this paragraph as often as it determines is
necessary. If Bank does not notify Supplier of

     trained and experienced to identify or resolve most support issues and
     shall respond to all Bank requests for support within 15 minutes after
     receiving a Bank request for assistance.

          (ii)  To enable Bank to escalate its support requests for issues that
     cannot be resolved by a help desk technician or for circumstances where a
     help desk technician does not respond within the time specified, Supplier
     shall deliver to Bank and keep current a list of persons and telephone
     numbers, including pager numbers, (the "Calling List") for Bank to contact.
     The Calling List shall include (1) the first person to contact if a
     question arises or problem occurs, and (2) the persons in successively more
     responsible or qualified positions to provide the answer or assistance
     desired.  If Supplier does not respond promptly to any request by Bank for
     telephone consultative service, then Bank may attempt to contact the next
     more responsible or qualified person on the Calling List until contact is
     made and a designated person responds to the call.

     (c)  Error Correction.
          ---------------- 

          (i)   For Class 1 Errors, Supplier shall provide a Correction or
     workaround reasonable in Bank's judgment within the Repair Period after
     Bank reports the Error, or within twelve hours if no other Repair Period is

     to work with Bank without interruption or additional charge, until Supplier
     provides a Correction or workaround reasonable in Bank's judgment.

          (ii)  For Class 2 Errors, Supplier shall take reasonable steps to
     provide a Correction or a workaround reasonable in Bank's judgment within
     one (1) Business Day after Bank reports the Error. These steps shall
     include assigning fully-qualified technicians to work with Bank during
     Bank's regular business hours until Supplier provides a workaround
     reasonable in Bank's judgment or a Correction or Bank determines after
     consultation with Supplier that such a workaround or Correction cannot be
     produced by Supplier's technicians.

          (iii) For Class 3 Errors, Supplier shall correct the Errors by all
     reasonable means. Supplier shall correct Software Class 3 Errors caused by
     the Object Code by modifying Source Code and distributing the modified
     Software to Bank no later than the next Update, unless Supplier has
     scheduled release of such Update less than ten (10) days after Bank's
     notice, in which case Supplier shall correct the Error no later than the
     following Update.

                                       8
<PAGE>
 
          (iv)  Without limiting Supplier's obligations under this Section, if
     Supplier does not deliver a Correction for an Error within the times
     allowed by this Section (whether Supplier has delivered a reasonable
     workaround or not), Supplier shall provide instead, a written analysis of
     the problem and a written plan to supply Bank with a Correction.

     (d)  Remedies.
          ---------

          (i)   If Supplier fails to provide a reasonable workaround or
     Correction for a Class 1 Error within the Repair Period, Supplier shall pay
     Bank, as liquidated damages for the costs Bank will incur as a result of
     the Class 1 Error and not as a penalty, the sum of 2/365 of the Maintenance
     Fees, expressed as an annual charge, for each additional day or part
     thereof (not to exceed 90 days) that Supplier fails to provide a reasonable
     workaround or a Correction for the Class 1 Error.

          (ii)  If Supplier fails to provide a reasonable workaround in Bank's
     judgment or Correction for a Class 2 Error within three Business Days after
     Bank reports the Error, Supplier shall pay Bank, as liquidated damages for
     the costs Bank will incur as a result of the Class 2 Error and not as a
     penalty, the sum of 1/365 of the Maintenance Fees, expressed as an annual
     charge, for each additional day or part thereof (not to exceed 60 days)
     that Supplier fails to provide a reasonable workaround or a Correction for
     the Class 2 Error.

          (iii) In each case of Class 1 or Class 2 Errors for which Supplier
     does not deliver a reasonable workaround or Correction on the schedule
     called for in the preceding paragraphs (i) and (ii), respectively, Supplier
     shall also credit Bank the pro rata portion of Maintenance Fees that would
     otherwise be payable from the date Bank first reported the Error until
     Supplier provides a Correction, in recognition that Maintenance Services
     during that period have not achieved their objective. If Supplier fails to
     provide a Correction within 30 days after Bank first reported the Class 1
     or Class 2 Error, Bank may terminate this Agreement for Supplier's material
     breach. Liquidated damages shall cease to accrue upon such termination.

          (iv)  Without limitation of Supplier's obligations above, Bank may, at
     its option, use any previous version or release of the Software in which a
     Class 1 or Class 2 Software Error does not occur or can be worked around,
     and Supplier shall provide Maintenance Services at no charge, with respect
     to that version until Supplier provides a Correction.

          (v)   The parties agree that the liquidated damages called for in this
     Section are reasonable in light of the harm that will be caused by such
     Errors, the difficulties of proof of loss and the inconvenience and
     infeasibility of otherwise obtaining an adequate remedy.

          (vi)  Liquidated damages shall be excused to the extent Errors are
     caused by actions or omissions of Bank.

     (e)  Diagnostic Information.  At Supplier's reasonable request, Bank shall
          ----------------------                                               
submit to Supplier a listing of output and such other data as Supplier
reasonably may request in order to reproduce operating conditions similar to
those present when Bank detected the Error.

infringe upon any patent, copyright, trade secret or other proprietary right of
any third party ("Intellectual Property Right"). Supplier shall defend or settle

proceeding, including appeals, negotiations and any settlement or compromise
thereof, provided that Bank shall approve the terms of any settlement or
compromise.

      (b)  If any Product or part thereof furnished under this Agreement,
including, without limitation, software, service, system design, equipment or
documentation, becomes, or in Bank's or Supplier's reasonable opinion is likely
to become, the subject of any claim, suit, or proceeding arising from or
alleging infringement of, or in the event of any adjudication that such Product
or part thereof infringes on, any Intellectual Property Right, Supplier, at its
own expense shall take the following actions in the listed order of preference:

           (i)  secure for Bank the right to continue using the Product or part
      thereof; or if commercially reasonable efforts are unavailing.

           (ii) replace or modify the Product or part thereof to make it
      noninfringing; provided, however, that such modification or replacement
      shall not degrade the operation or performance of the Product.

      (c)  This indemnity shall not extend to any claim of infringement
resulting from Bank's unauthorized modification of Product or from use or
incorporation of Product in a manner for which the Product is not designed with
products not provided by Supplier or by or for Bank with Supplier's approval.

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

The Product and any media used to distribute it contain no computer

purpose is to disrupt, damage or interfere with Bank's use of its computer and
telecommunications facilities for their commercial, test or research purposes.
Harmful Code shall include, without limitation, any instrumentality that will

Bank as long as it shall not be in default hereunder.

      (b)  Supplier warrants that it has full power and authority to grant the
rights herein granted without the consent of any other person. Supplier will
indemnify Bank and hold it harmless from and against any loss, cost, liability

condition of this Agreement, the other party may terminate this Agreement. The
party seeking to terminate this Agreement shall give the other party at least
thirty days' prior written notice of any of the foregoing claimed to be a basis
for termination, and the Agreement shall terminate on the date specified in the
notice if the party receiving the notice has by then failed to correct or remedy
the situation. The party charged with material breach may initiate the
procedures of the Section entitled Dispute Resolution.

     (b)  If a voluntary or involuntary petition is commenced by or against
Supplier under the United States Bankruptcy Code (Title 11, U.S. Code, referred
to hereafter as the "Code"), or Supplier becomes insolvent, or any substantial
part of Supplier's property becomes subject to any levy, seizure, assignment,
application or sale for or by any creditor or governmental agency, or a receiver
should be appointed for Supplier, Bank may terminate this Agreement by following
the procedure of the preceding paragraph G-7(a). The parties agree that all
software delivered pursuant to this Agreement and the documentation therefor
constitute "intellectual property" under Section 101(35A) of the Code (11 U.S.C.
(S) 101(35A)). Supplier agrees that if it, as a debtor-in-possession, or if a
trustee in bankruptcy for Supplier, in a case under the Code, rejects this
Agreement, Bank may elect to retain its rights under this Agreement as provided
in Section 365(n) of the Code. Bank, and any intellectual property rights,
licenses or assignments from Supplier of which Bank may have the benefit, shall
receive the full protection granted to Bank by applicable bankruptcy law.

     (c)  The licenses granted in this Agreement shall not terminate for any
reason unless Bank fails to pay in full the undisputed portion of license fees

termination in order to achieve the fundamental purposes of this Agreement,

indemnifying party, its agents or employees.

     (b)  Neither party shall be liable to the other hereunder for any special,
indirect, consequential or exemplary damages, including, but not limited to,

G-9.  FORCE MAJEURE
      -------------

      (a)  No failure, delay or default in performance of any obligation of a
party to this Agreement shall constitute an event of default or a breach of this
Agreement, to the extent that such failure to perform, delay or default arises
out of a cause, existing or future, that is beyond the control and without
negligence of the party otherwise chargeable with failure, delay or default;
including, but not limited to: action or inaction of governmental, civil or
military authority; fire; strike; lockout or other labor dispute; flood; war;
riot; theft; earthquake and natural disaster. The affected party shall take
action to minimize the consequences of any such cause. Either party desiring to
rely upon any of the foregoing as an excuse for failure, default or delay in
performance shall, when the cause arises, give to the other party prompt notice
in writing of the facts which constitute such cause; and, when the cause ceases
to exist, give prompt notice thereof to the other party. This Section shall in
no way limit the right of either party to this Agreement to make any claim
against third parties for any damages suffered due to said causes.

      (b)  If any performance date under this Agreement is postponed or extended
pursuant to this Section for longer than 60 calendar days, Bank may, by written
notice given during the postponement or extension, terminate Supplier's right to
render further performance after the effective date of termination without
liability for that termination.


G-10. TAXES
      -----

Bank shall pay or reimburse Supplier for sales and use taxes, where applicable,
and any other governmental charges levied, imposed or assessed on Product
furnished to Bank or on this Agreement, excluding, however, ordinary personal
property taxes assessed against or payable by Supplier, taxes based upon
Supplier's net income and Supplier's corporate franchise taxes.  Alternatively
to such payment or reimbursement, Bank may satisfy its obligation in this
Section by providing Supplier with an applicable exemption certificate.
Supplier shall furnish Bank with invoices showing separately itemized amounts
due under this Section.  If Bank pays or reimburses Supplier under this Section,
Supplier hereby assigns and transfers to Bank all of its right, title and
interest in and to any refund for taxes paid.  Any claim for refund of taxes
against the assessing authority may be made in the name of Bank or Supplier, or
both, at Bank's option.  Bank may initiate and manage litigation brought in the
name of Bank or Supplier, or both, to obtain amounts paid under this Section.
Supplier shall cooperate fully with Bank in pursuing any refund claims,
including any related litigation or administrative procedures.


G-11. ASSIGNMENT
      ----------

Neither party shall assign any of its rights nor delegate any of its obligations
under this Agreement without the prior written consent of the other party,
provided that Bank may assign its rights and benefits and delegate its duties
and obligations under this Agreement to its Affiliates.  Supplier shall not
subcontract any of its rights and obligations hereunder to one or more third
parties without Bank's prior written approval.  Any prohibited assignment or
delegation shall be null and void.

G-12.  DISPUTE RESOLUTION
       ------------------

The following procedure will be adhered to in all disputes arising under this
Agreement which the parties cannot resolve informally.  The aggrieved party
shall notify the other party in writing of the nature of the dispute with as
much detail as possible about the deficient performance of the other party.  The
Project Managers shall meet (in person or by telephone) within seven days after
the date of the written notification to reach an agreement about the nature of
the deficiency and the corrective action to be taken by the respective parties.
The Project Managers shall produce a report about the nature of the dispute in
detail to their respective management.  If the Project Managers are unable to
agree on corrective action, senior managers of the parties having authority to
resolve the dispute without the further consent of any other person
("Management") shall meet or otherwise act to facilitate an agreement within 14
days of the date of the written notification.  If Management cannot resolve the
dispute or agree upon a written plan of corrective action to do so within seven
days after their initial meeting or other action, or if the agreed-upon
completion dates in the written plan of corrective action are exceeded, either
party may request arbitration as provided for in this Agreement.  Except as
otherwise specifically provided, neither party shall initiate arbitration,
mediation or litigation unless and until this dispute resolution procedure has
been employed or waived.


G-13.  ARBITRATION
       -----------

       (a)  Mandatory Arbitration. Any controversy or claim between or among the
parties, including, but not limited to, those arising out of or relating to this
Agreement or any agreements or instruments relating hereto and any claim based
on or arising from an alleged tort, shall at the request of a party be
determined by arbitration. The arbitration shall be conducted in San Francisco,
California in accordance with the United States Arbitration Act (Title 9, U.S.
Code), notwithstanding any choice of law provision in this Agreement, and under
the auspices and rules of the American Arbitration Association then in effect.
Each party may serve a single request for production of documents. If disputes
arise concerning these requests, the arbitrators shall have sole and complete
discretion to determine the disputes. The arbitrators shall give effect to
statutes of limitation in determining any claim, and any controversy concerning
whether an issue is arbitrable shall be determined by the arbitrators. The
arbitrators shall deliver a written opinion setting forth findings of fact,
conclusions of law and the rationale for the decision. The arbitrators shall
reconsider the decision once upon the motion and at the expense of a party. The
Section of this Agreement entitled Confidentiality shall apply to the
arbitration proceeding, all evidence taken and the opinion, which are the
Confidential Information of both parties. Judgment upon the decision rendered by
the arbitrators may be entered in any court having jurisdiction. The institution
and maintenance of an action for judicial relief or pursuit of a provisional or
ancillary remedy shall not constitute a waiver of the right of either party to
submit the controversy or claim to arbitration if the other party contests such
action for judicial relief.

       (b)  Provisional Remedies. No provision of this Section G-13. Arbitration
shall limit the right of a party to this Agreement to obtain provisional or
ancillary remedies from a court of competent jurisdiction before, after, or
during the pendency of any arbitration. The exercise of a remedy does not waive
the right of either party to resort to arbitration.

proceeding.


G-15.  RELATIONSHIP OF THE PARTIES
       ---------------------------

The parties are independent contractors.  Nothing in this Agreement or in the

agency, partnership, employment or joint venture relationship between the
parties.  Each party shall be deemed to be acting solely on its own behalf and,
except as expressly stated, has no authority to pledge the credit of, or incur
obligations or perform any acts or make any statements on behalf of, the other

1.   DESCRIPTION OF PILOT PROGRAM

     A.   GOAL

          To create a pilot program testing the feasibility of using smartcards
          with digital IDs to provide secure access and client authentication
          to Bank of America's On-line Banking Services. Banking Services are
          not defined for pilot, but will be defined for production roll-out.

          The purpose of this project is to deploy digital certificates on
          SmartCards and to determine the feasibility of performing this on a
          large scale and to what degree we can use the digital certificate to
          authenticate a user/client.

     B.   SMARTCARD ISSUANCE

          1) Clients are chosen for Pilot Program
          2) User Information are imported or hand-entered into Smartcard 
             Issuance System
          3) Random PIN for smartcard access is determined
          4) Personalized Smartcard is issued with a 60-day temporary 
             (unregistered) Bank of America branded VeriSign certificate
          5) Smartcard, Client-side Web Access software, and instructions are 
             delivered to Client
          6) PIN is delivered to Client

     C.   REGISTRATION

          1) Client installs smartcard reader and software
          2) Client goes to Bank of America registration website
          3) Client must insert smartcard (unregistered) in reader and enter PIN
             in order to gain access to the registration website.
          4) Client must additionally provide Banking Services user ID and
             password to authenticate himself to Bank of America registration
             website
          5) Registration process begins
          6) Client's temporary digital ID is replaced with a one year,
             registered Bank of America branded VeriSign digital ID
          7) Upon completion of registration, client is directed to the Bank of
             America On-line Banking Website
          8) Client must insert smartcard (registered) in reader and enter PIN 
             in order to gain access to the On-line Banking Website

     D.   MAINTENANCE

          1) If a client blocks their PIN, they may contact a designated Bank of
             America Representative who can assist them with unblocking their
             PIN over the phone.
          2) Client runs PIN Unblock (client-side) application

      3) A random code is generated
      4) Bank Representative runs PIN Unblock (server-side) application
      5) Client reads the code to Representative
      6) Representative enters code and client's account number into server-side
         application
      7) Server-side application looks up SO PIN using Account Number and 
         provides an encoded response code
      8) Client enters response code which Unlocks PIN
      9) Client is prompted for new User PIN
     10) New User PIN is confirmed with Client

                                  SCHEDULE D
                            PRODUCT SPECIFICATIONS


D-1.  PRODUCT DESCRIPTION
      -------------------

      The Software to be delivered hereunder consists of the following:

      (a) Litronic Profile Manager ("Profile Manager"):is Bank Resident Software
                                                          ----------------------
used for the issuance of SmartCards.

        1.  General Parameters.
            ------------------ 

            (A) Profile Manager is a secure end-to-end solution for the
                management of SmartCard based systems from initialization
                (secure generation) to secure backup and recovery of SmartCard-
                based keys and certificates. Profile Manager operates as a 
                stand-alone or online application and may be used in conjunction
                with customizable modules to expand and adapt to specific system
                requirements.

            (B) Profile Manager securely generates custom SmartCards for any
                user in the system. SmartCard initialization is performed by the
                security officer, not an end user, for fail-safe installation of
                the certificate on the SmartCard. Security Officers can control
                security by generating and backing-up keys and certificates in a
                secure environment. Profile Manager supports international
                standards including but not limited to SSL, S/MIME, PKS #11,
                PC/SC, and CDSA, and enables the generation of X.509v3
                certificates, public/private keypairs, symmetric keys and user
                profile information.

            (C) Profile Manager provides integration with a secure database.
                SmartCard-based information is encrypted with the security
                officer's 168-bit Triple DES key PIN-protected SmartCard and
                optionally stored in a secure database. The security officer can
                access information from an existing user and issue a duplicate
                card if the card is lost or blocked.

            (D) Profile Manager integrates with existing employee and customer
                databases so that the security administrator is not required to
                re-key user data for card initialization.

            (E) Profile Manager may be used to modify privileges or access keys
                by adding and deleting items from an existing user card. Keys
                may be modified after the initial generation of the card and any
                changes to a card creates a new backup entry in the database.

            (F) Profile Manager integrates with Litronic's NetSign(TM), NetSign
                PRO(TM) and other Litronic SmartCard-enabled products to provide
                a complete solution for all enterprise security needs including,
                but not limited to, secure web access, digitally signed and
                encrypted email, desktop file encryption and remote network
                access.

        2.  Modules.
            ------- 

            (A) Description of Litronic Key Generation Module: The Litronic Key
                Generation Module supplies all of the key generation tasks of
                the Profile Manager. The system may be configured to produce
                different types of keys. The Profile Manager generates 1024-bit
                RSA public/private key pairs for digital signing and
                authentication and 168-bit triple DESA keys for encryption and
                decryption. The system may also be configured to support RSA
                keys of different lengths, triple DES keys of different lengths
                and other types of keys such as DSA keys. This module interfaces
                with a Luna Card.

            (B) Litronic Administrator Authentication Module: The security
                officer is authenticated into a Profile Manager through the
                Administrator Authentication Module. The security officer
                inserts an administrator SmartCard into an administrator
                SmartCard Reader. The administrator card contains the optional
                signing certificate (if the system is not using an external
                certificate authority) and a 168-bit Triple DES key that is used
                to encrypt/decrypt all the vital information (keys,
                certificates, Unblock PINS, etc.). Access to the system requires
                an administrator card. The encryption is accomplished solely on
                a SmartCard. The administrator's Triple DES key is never exposed
                to the host computer system. This eliminates the threat of the
                system being compromised by a Trojan Horse, a program designed
                to anonymously "sniff" information resident in a host computer.

            (C) Litronic SmartCard Issuance Module: The Litronic SmartCard
                Issuance Module provides the means for initializing SmartCards
                that are generated by the system. This module performs the card
                initialization in either single or bulk mode. It supports output
                devices such as the SmartCard Reader and Datacard.

            (D) Litronic Certificate Module: The Litronic Certificate Module
                provides the certificates for the key pairs generated by Profile
                Manager. The system default creates its own root key certificate
                for signing all of the Leaf Certificates. A Leaf Certificate is
                a certificate at the bottom of a certificate chain used for
                authentication and identification and is not enabled to sign new
                certificates. The Profile Manager can be incorporated with
                external Certificate Authorities to provide a more complete
                certificate management system to compliment the SmartCard
                management system.

            (E) Litronic Custom Data Object Module: The Litronic Custom Data
                Object Module allows additional information to be stored onto
                the SmartCard. Customized applications can pull the custom data
                object module for the card for its own purpose. The Profile
                Manager currently deploys two different custom data object
                modules: NetSign PRO(TM)'s Point'n Crypt Blowfish key and
                NetSign PRO(TM)'s User Profile information for Secure Start and
                Secure Dial features. Customized data objects can easily be
                integrated to support any number of SmartCard aware
                applications. Customized SmartCard aware applications may be
                written into a programming language of choice. Languages,
                including but not limited to, C, 

                                       2
<PAGE>
 
                C++, Java(TM), ActiveX, Delphi, and Visual Basic are supported.
                The Profile Manager has the ability to initialize data on the
                deployed SmartCard that is specific to a custom application. An
                In-house application which requires the security and portability
                of a SmartCard can be written using the SDK and Profile Manager
                can initialize SmartCards with the data values for the
                application. Users can immediately use a Profile Manager issued
                SmartCard with the custom application in addition to all the
                features available in NetSign and NetSign PRO(TM).

            (F) Litronic Data I/O Module: The Litronic Data I/O Module provides
                the means for sending and retrieving data for the use of issuing
                and backing up SmartCards. The Profile Manager can support many
                different methods for data access: 1. ODBC (3) - Profile manager
                can send and retrieve data to/from an SQL database via an ODBC
                connection. 2. Flat File - User information from a flat file can
                be imported into the Data I/O Module. The Profile Manager keeps
                a log of events for every transaction performed within the
                system. When a card is crated, restored, returned, unblocked,
                etc., that event is logged and time dumped. The log file entries
                are stored in the same SQL database that the system uses to
                store user information and backup entries.

            (G) Litronic Online/Update Module: The Litronic Online/Update Module
                is an external to the normal Profile Manager executable yet it
                still accesses the Profile Manager database(s). The database may
                be divided into three sections (administrator card protected,
                password protected and clear) and the Online/Update Module must
                have the proper privileges to interact with the database
                sections in which it is interested. It can handle tasks that
                require database interaction but are not necessarily associated
                with SmartCard issuance/recovery. The normal Profile Manager
                executable should be used for most SmartCard issuance/recovery
                functions. Online/Update can handle such things as certificate
                inquiries, Online remote PIN unblocking, Online remote
                certificate replacement, etc. Any functionality may be
                incorporated as long as the module has the necessary permissions
                to the database.

            (H) Litronic Unblock PIN Service Module: The Litronic Unblock PIN
                Service Module allows for PIN-blocked user cards to have their
                PIN unblocked remotely without requiring the user to physically
                bring the SmartCard to the Profile Manager station. The service
                involves an application run by a technical support
                representative and a Java(TM) applet run by the end user's
                browser. The technical support application queries the Profile
                Manager database, presents the necessary password to access the
                Unblock PIN for the specific card, and "blinds" this PIN using
                an algorithm known by both the tech support application and the
                Java(TM) applet. The Tech support representative can then read
                the blinded PIN over the telephone and the user types it into
                the applet. The applet un-blinds the PIN and unblocks the card
                so that the user is free to choose a new PIN. The tech support
                representative could optionally be taken out of the loop in this
                process; however, that would imply that the end user's browser
                has some physical connection to the Profile Manager database
                which may violate the security model.

            (I) Litronic Certificate Service Module: The Litronic Certificate
                Service Module allows for certificates to be replaced remotely
                by using a Java(TM) applet and a corresponding Java(TM) server
                which has access to the Profile Manager database. In the system,
                the original private key on the issued SmartCard is retained so
                that a new keypair does not need to be generated in an insecure
                environment. Only the certificate itself is replaced, and the
                new certificate is then noted in the database.

SMARTCARD ISSUANCE

The following example illustrates the process that is undertaken when issuing a 
user smartcard.

                            [DIAGRAM APPEARS HERE]

FIGURE 1

1.   The Administrator selects a user from the Data I/O Module and retrieves the
     user information.
2.   The fields that will be used to construct the distinguished name for the
     certificate are extracted from the user information and sent to the
     certificate module.
3.   An RSA public/private key pair is generated for the user (from the Key
     Generation Module) and sent to the certificate module and the ProFile
     Manager.
4.   The certificate information and the public key are encoded and placed in a
     PKCS-10 Certificate Signing Request, which is then signed and encrypted. It
     is sent to the Certificate Authority URL.
5.   A signed and encrypted certificate is sent back to the certificate module.
6.   When the certificate module receives the encrypted certificate, it is 
     decrypted and sent to the ProFile Manager
7.   The certificate, public/private keypair, and any optional custom data are
     sent to the administrator authentication module to be encrypted with the
     Administrator's 168-bit triple DES key.
8.   The encrypted data is sent to the Data I/O module for storage.
9.   The non-encrypted data is sent to the smartcard issuance module to be 
     printed onto the smartcard.

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, except for Note 5 which is as of May 5, 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.
