financial statements and the notes thereto appearing elsewhere in this
Prospectus. Except as otherwise indicated herein, the information in this
Prospectus assumes (i) the completion of the recapitalization of the Company and
certain related entities (the "Recapitalization," as more specifically defined
under "Certain Transactions - Pending Recapitalization") to be effected
immediately prior to the closing of the Offering, (ii) an initial public
offering price of $8.00 per share, the midpoint of the range set forth on the
cover page of this Prospectus, and (iii) the 30-day over-allotment option
granted to the Underwriters is not exercised. Unless the context otherwise
requires, references in this Prospectus to "ICARUS" or the "Company" include
ICARUS International, Inc., a Maryland corporation, and its predecessors and
consolidated subsidiaries. INVESTORS SHOULD CAREFULLY CONSIDER THE INFORMATION
SET FORTH UNDER THE HEADING "RISK FACTORS."

                                   THE COMPANY

         ICARUS International, Inc. develops automated desktop engineering
("AutoDE") software for the process manufacturing segments of the chemical,
petroleum refining, pulp and paper, food and other industries. Process
manufacturing plants make products in bulk quantities through various chemical,
physical, and other operations. The Company's 300-plus customers are primarily
large, multinational corporations that own and operate process manufacturing
plants or provide engineering and construction services to such
owner-operators. The Company's customers include such companies as Mitsubishi
Chemical Corporation, Shell Oil Company, The Mead Corporation, Campbell Soup
Company and Fluor Daniel, Inc.

         Industry sources indicate that more than 15,000 process manufacturing
plants are now in operation worldwide and that global spending on process
manufacturing plant construction projects will exceed $160 billion in 1998--an
all-time high. The Company's current software products automate important steps
in the "decision engineering" process through which a customer's engineering
staff evaluates the technological and economic feasibility of the construction
or modification of a process manufacturing plant and senior executives determine
whether to proceed with a proposed project. Despite the importance of this
decision, which may involve a capital investment in excess of one billion
dollars, these executives usually have only a limited ability to manage the
conventional decision engineering process, which is time-consuming,
labor-intensive, imprecise and expensive.

         The Company's current products directly address a number of the
deficiencies in the conventional decision engineering process by
"re-engineering" the process to take full advantage of today's desktop computing
technology. The Company's products enable engineers to simulate, model and
analyze the design, cost and time requirements of a proposed project more
quickly and less expensively than they can using conventional


                                      - 1 -
<PAGE>   6
engineering methods. ICARUS products also enhance senior executives' ability to
focus the decision engineering process on business priorities. With more timely
and accurate information that integrates business considerations with
sophisticated engineering analysis, senior executives can make faster, better
informed and more confident decisions. Benefits arising from the use of the
Company's decision engineering software products include more effective
strategic planning, faster reaction to market developments and improved plant
operating efficiency, all of which enhance the customer's competitive position.

         In addition to the Company's decision engineering products, other
AutoDE software products automate important steps in the "plant engineering"
process, which occurs after the decision to proceed with a project has been
made. These products also facilitate construction scheduling and cost estimation
for smaller projects at existing plants.

         The Company's strategy is to expand its portfolio of integrated AutoDE
software products to meet customer needs in every stage of the process
manufacturing plant lifecycle--from the business development decision to
consider entering a process manufacturing segment, through the process and cost
engineering analysis of a specific proposed plant, to the detailed engineering,
construction scheduling and operations and maintenance activities that follow
the decision to proceed with a proposed plant. For the decision engineering
process, which encompasses business development, process engineering and cost
engineering, ICARUS currently offers process engineering and cost engineering
products. The Company plans to supplement these products and also to release a
new suite of business development products designed to enable senior executives
to analyze high-level, early-stage technological and economic feasibility
issues. This suite of products also will assist senior executives in ensuring
that their engineering staffs are focused on the business impact of their
engineering work. For the plant engineering process, which encompasses detailed
engineering/procurement, construction scheduling and operations and maintenance,
ICARUS currently offers construction scheduling and cost estimation products and
plans to release an object database product that will support plant engineering
applications such as computer-aided engineering ("CAE") or computer-aided design
("CAD") production of detailed construction drawings. A more detailed
enumeration of the elements of the Company's strategic plan is set forth under
the caption "Business-Strategy."

         ICARUS markets its products on a world-wide basis through its direct
sales force operating from its home office in Rockville, Maryland and its other
offices in Houston, Texas, Altrincham, England, and Tokyo, Japan. The Company
also has independent sales representatives located in Argentina, Australia,
Brazil, Colombia, France, Germany, India, Saudi Arabia, South Africa, South
Korea, Venezuela and certain independent republics of the former Soviet Union,
and a sales representative that sells into the People's Republic of China. As
part of its marketing effort, ICARUS participates in domestic and international
trade shows, publishes a newsletter, advertises in engineering and other trade
magazines, and holds annual user conferences in the United States, Europe and
Japan.

         The primary source of the Company's revenues are single-year and
multi-year term license fees. At October 31, 1997, 57.5% of the Company's
licenses had a remaining life of one year or more. For the twelve-month period
ended October 31, 1997, 68.5% of licensed authorized users whose licenses
expired during such period elected to renew such licenses (including renewals
that involved the substitution of another ICARUS product) and 49.1% of all new
licenses sold to authorized users were for a term of two or more years. The
Company believes that its license renewal rates and ability to sell multi-year
term licenses are important historical financial strengths. ICARUS also derives
revenue from technical support and training for its customers' employees,
maintenance agreements and consulting services.

         The name "ICARUS" is an acronym for Industrial Computer Application
Retrieval and Utility Systems, which was adopted when ICARUS commenced business
operations in 1969. The Company's principal offices are located at One Central
Plaza, 11300 Rockville Pike, Rockville, Maryland 20852; its telephone number is
(301) 881-9350.

                                  RISK FACTORS

         The shares offered hereby involve a high degree of risk. The following
risk factors should be considered carefully in addition to the other information
in this Prospectus before investing in shares of the Common Stock offered
hereby. The discussion in this Prospectus contains certain forward-looking
statements that involve risks and uncertainties, such as statements of the
Company's plans, goals, objectives, expectations and intentions. The cautionary
statements made in this Prospectus should be read as being applicable to all
related forward-looking statements wherever they appear in this Prospectus.
Prospective investors in the shares of Common Stock offered hereby are cautioned
that, while the forward-looking statements reflect the Company's good faith
beliefs, they are not guarantees of future performance and involve known and
unknown risks and uncertainties and that the Company's actual results could
differ materially from those discussed herein. Some of the factors that could
cause or contribute to such differences include those discussed below, as well
as those discussed elsewhere herein.

         Market Acceptance of the Company's Products. The success of the Company
is dependent upon continued and increased use in the process manufacturing
segments of various industries of CAE software in general, and of the Company's
AutoDE software products in particular. Market acceptance of the Company's
existing and future products depends on several factors including the ease with
which the products can be implemented and used, the performance and reliability
of the products, the range of tasks that the products can perform, the degree to
which users achieve expected cost savings and productivity gains, and the extent
to which the Company's customers and prospective customers are able to implement
alternative approaches to meet their business development, engineering,
construction scheduling and operations and maintenance needs. Some of the above
factors are beyond the Company's control. There can be no assurance that the
Company's customers will realize the intended benefits of the Company's products
or that the Company's products will achieve continued or increased market
acceptance. Any significant or ongoing failure to achieve such benefits or to
maintain or increase market acceptance would substantially restrict the future
growth of the Company and could have a material adverse effect on the Company's
business, operating results and financial condition. See "Business - The
Decision Engineering Process" and "- Competition."

         Dependence on Contract Renewals. The Company derives a significant
portion of its total revenue from the renewal of license agreements with
existing customers. The Company expects contract renewals to account for an
increasing portion of the Company's total revenue in the future to the extent
that the Company increases the number of contracts for renewing customers. The
Company's license agreements generally have one to five year terms and do not
obligate customers to renew after the expiration of their licenses. The
Company's ability to secure renewals may be affected by, among other factors,
its ability to deliver consistent, high-quality and timely product enhancements
and support services; ownership, management or personnel changes within customer
organizations, including acquisitions of customers by other companies; the
general global investment climate for the process manufacturing segments of
various industries; customer capital budget constraints; the introduction of
competing products by third parties; political and economic stability in
customers' markets and other factors, many of which are beyond the control of
the Company. There can be no assurance that the Company will be able to maintain
its historical renewal rates and any significant or ongoing decline in renewal
rates would have a material adverse effect on the Company's business, operating
results and financial


                                      - 6 -

condition. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations - Overview."

         Risks Associated with Continued Product Development; Rapid
Technological Change. The market for CAE software is characterized by rapid
technological change, quickly evolving industry standards and frequent changes
in customer requirements. As a result, new products or product features are
continually being introduced by CAE software companies. The Company's future
results of operations will depend in part upon the Company's ability to avoid
product obsolescence by anticipating and responding to the changes described
above in a timely manner. There can be no assurance that the Company will be
successful in developing and marketing new products and features or that the
Company will not experience difficulties that could delay or prevent the
successful development, introduction and sale of such new products and features
or that such new products and features will adequately meet the requirements of
the marketplace and achieve market acceptance. In particular, the Company may
face additional risks in the development of products which are intended to
address different stages of the process manufacturing lifecycle resulting from
the Company's limited knowledge and experience in developing products for such
stages. The Company may also face additional risks related to the process
manufacturing requirements of certain industries not currently addressed by the
Company's products, the Company's attempt to sell new or existing products into
new markets and its dependence upon the contractual performance of new strategic
alliance "partners." See "Business - Strategy."

         The Company in the past has experienced delays in the release of new
products and new product features due primarily to the lack of funding to
support product development, difficulties in the allocation and/or recruitment
of required personnel and delays in receipt of necessary technology and supplies
from third parties upon whom the Company was dependent. If any new significant
products or product features are materially delayed or if they fail to achieve
market acceptance, the Company's business, operating results and financial
condition would be materially adversely affected. In addition, the introduction
or announcement of new product offerings or new product features by the Company
or the Company's competitors may cause customers to defer or forgo purchases of
current versions of its products, which could, in turn, have a material adverse
effect on the Company's business, operating results and financial condition. See
"Business - Products and Product Development."

         The success of the Company's products in the future will depend, in
part, on technological factors, including the evolution of desktop and network
operating systems and the migration of existing and potential customers from
centralized mainframe-based computing systems to distributed client-server
computing systems. There can be no assurance that the Company will successfully
develop new AutoDE software products (and updated versions of existing products)
that will respond adequately to changes in existing operating systems and the
potential introduction of new operating systems or that such development, even
if successful, will be completed on a timely basis. Neither can there be any
assurance that the Company's current efforts to develop client-server-compatible
products will be successful. A failure in either case could have a material
adverse effect on the Company's business, operating results and financial
condition.

         Fluctuations in Future Operating Results. The Company's operating
results have fluctuated in the past and will in the future likely fluctuate
significantly from quarter to quarter or on an annual basis as a result of a
number of factors, including, but not limited to, the size and timing of
customer orders, delays in renewals or failure of existing customers to renew
their licenses with the Company when their current licenses expire, the length
of the Company's sales cycle, changes in contract terms (including terms
affecting the timing of recognition of license revenue) and the rate at which
such changes are made, timing of new product announcements and introductions by
the Company and its competitors, the Company's ability to develop, introduce and
market new products and product enhancements, market acceptance of the Company's
products, deferrals of customer orders in anticipation of new products or
product enhancements, the Company's ability to control costs, (including the
hiring of new employees), political instability in, or trade embargoes with
respect to, foreign markets, changes in the Company's management team, and
fluctuating economic conditions. The Company's future operating results may
fluctuate as a result of these and other factors, which could have a material
adverse effect on the Company's business, operating results and financial
condition. It is possible that in some future quarter the Company's operating
results will be below the expectations of public market analysts and investors.
In such event, the price of the Company's Common Stock would likely be adversely
affected to a material degree. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations - Selected Quarterly Operating
Results."

         The Company ships software products within a short period after receipt
of a new order and typically does not have a material backlog of unfilled
orders. Revenue in any quarter is substantially dependent on orders booked and
license renewals in that quarter and are not predictable with any degree of
certainty. The Company has recently incurred substantial expenses associated
with product development and increased staffing of its direct sales force with
no certainty that the incurrence of such expenses will result in future
revenues. In addition, because a large portion of the Company's expense levels
are fixed (i.e., relate to salaries, benefits and occupancy expenses), if
revenue is below expectations in any given quarter, then the adverse effect may
be magnified by the Company's inability to adjust spending in a timely manner to
compensate for any revenue shortfall. In addition, a customer's purchase of the
Company's products generally involves a significant commitment of capital with
possible attendant delays frequently associated with authorization procedures
for substantial capital expenditures within large organizations. Moreover, the
Company believes that because some customers are purchasing larger and more
complex AutoDE software products, the Company's average licensed user fees have
been increasing and purchases of the Company's products require approval at
higher executive levels. For these and other reasons, the sales cycles for the
Company's products can be lengthy and are subject to a number of significant
risks over which the Company has little or no control. As a result of the large
dollar amounts represented by a single order, the timing of the receipt of an
order can have a significant impact on the Company's revenues and earnings for a
particular period. Any significant or ongoing failure to reach definitive
agreements with customers, including renewals of current licensing agreements
upon their expiration, would have a material adverse effect on the Company's
business, operating results and financial condition.

         Ability to Attract and Retain Required Personnel. The Company believes
that its future business results will depend in significant part upon its
ability to attract and retain highly


                                      - 8 -
<PAGE>   13
skilled engineering, managerial and marketing personnel. Competition for such
personnel is intense, and any failure to attract and retain such personnel could
have a material adverse effect on the Company's business, operating results and
financial condition. In particular, the Company has found it difficult to
attract qualified engineering personnel in the past and no assurance can be
given that the Company will not have similar difficulties in the future.

         Intense Competition. The market for CAE software used in the process
manufacturing segments of various industries is intensely competitive. The
Company experiences competition primarily from its customers and potential
customers, which have developed, or may decide to develop, and/or maintain their
own software internally rather than purchasing commercial software products such
as those offered by the Company. As a result, the Company must continuously
educate existing and prospective customers about the advantages of purchasing
the Company's AutoDE software products and services. There can be no assurance
that these customers or other potential customers will perceive sufficient value
in the Company's products and services to justify licensing them. In addition,
customers or potential customers could enter into strategic relationships with
one or more of the Company's competitors to develop, market and sell competing
products and services.

         The Company has also experienced and expects to continue to experience
intense competition from current and future competitors, some of whom have
significantly greater financial, technical, marketing and other resources than
the Company. The Company's current direct third-party competitors include
Timberline Software Corporation and a number of smaller private companies. To a
lesser degree, ICARUS faces competition or potential competition from Aspen
Technology, Simulation Sciences Inc. and ChemStations, Inc. Many of the
Company's competitors may be able to respond more quickly to new or emerging
technologies and changes in customer requirements or to devote greater resources
to the development, promotion and sale of their products than can the Company.
Also, several of the Company's current and potential competitors have greater
name recognition and larger installed bases that could be leveraged to increase
market share at the Company's expense. The Company expects to face increased
competition as other established and emerging companies enter the CAE software
market in the process manufacturing sector of various industries and new
products and technologies are introduced. Increased competition could result in
price reductions, fewer customer orders, reduction in license renewals and loss
of market share, any of which could materially adversely affect the Company's
business, operating results and financial condition. In addition, current and
potential competitors have in the recent past made, and may in the future make,
strategic acquisitions, merge or establish cooperative relationships among
themselves or with third parties, thereby increasing the ability of their
products to address the needs of the Company's current or prospective customers.
Such competition could materially adversely affect the Company's ability to sell
new or renewal licenses and support agreements on terms favorable to the
Company. There can be no assurance that the Company will be able to compete
successfully against current and future competitors, and the failure to do so
would have a material adverse effect upon the Company's business, operating
results and financial condition. See "Business - Competition."

         Ability to Manage Growth. To the extent the Company experiences growth
in its business, it is expected that such growth would place a significant
strain on the Company's personnel and resources. The Company's ability to manage
future growth, if any, will depend on its ability to implement and improve
operational, financial and management


                                      - 9 -
<PAGE>   14
information and control systems on a timely basis, together with maintaining
effective cost controls, and any failure to do so could have a material adverse
effect on the Company's business, operating results and financial condition. No
assurance can be given that the Company will not experience such difficulties in
the future.

         Limited Line of Products and Services. The Company derives its revenues
from the licensing and sale of a limited number of products and services. The
Company currently offers four primary AutoDE software products, and the software
license revenue derived from such products constituted approximately 75.6% and
70.4% of the Company's total revenues for the six-month period ended October 31,
1997 and for fiscal 1997, respectively. As a consequence, in the event that the
Company were to experience a decline in the demand for one or more of its AutoDE
software products, such a decline could have a material adverse effect on the
Company's business, operating results and financial condition. See "Business -
Products and Product Development."

         Concentration of Revenue in the Chemical and Petroleum Refining
Industries. For the six months ended October 31, 1997 and for fiscal 1997, the
Company has derived a significant amount of its total revenue from software
licenses and services to companies in the process manufacturing segments of the
chemical and petroleum refining industries, which are highly cyclical
industries. Accordingly, the Company's future success is dependent to a
substantial degree upon the continued demand for its AutoDE software by
companies in the chemical and petroleum refining industries. The Company
believes that economic downturns in the U.S., Europe and Asia at different
times, and pricing pressures experienced by chemical and petroleum refining
companies in connection with cost containment measures, have led to delays and
reductions in certain capital and operating expenditures by many of such
companies in the past, and such delays or reductions will likely recur in the
future. Any such delays or reductions could have a material adverse effect on
the Company's business, operating results and financial condition. Further, the
Company's revenue in the past has been, and in the future may be, subject to
substantial period-to-period fluctuations as a consequence of general domestic
and foreign economic conditions, political developments and other factors
affecting spending in the chemical and petroleum refining industries. The
Company has developed new products and product features for, and has increased
its marketing efforts of its current products to, companies in the process
manufacturing segments of other industries. However, no assurance can be given
that such efforts will decrease the Company's concentration of revenues from the
chemical and petroleum refining industries in the foreseeable future. See
"Business - Strategy."

         Risks Associated with International Operations. A significant portion
of the Company's total revenue for the six months ended October 31, 1997 and for
fiscal 1997 was derived from customers whose licensed users are located outside
the United States. The Company's international operations are subject to risks
inherent in the conduct of international business, including unexpected changes
in regulatory requirements, exchange rates, export license requirements, tariffs
and other barriers, political and economic instability, limited intellectual
property protection, difficulties in collecting payments due from sales
representatives or customers, difficulties in managing its sales
representatives, difficulties in staffing and managing foreign subsidiary
operations, and potentially adverse tax consequences. Certain of the Company's
international sales are denominated in local currencies, and the impact of
future exchange rate fluctuations on the Company's operating results and
financial condition cannot be accurately predicted. The Company does not


                                     - 10 -
<PAGE>   15
currently engage in currency exchange rate hedging transactions, but the Company
will occasionally buy and sell different currencies to protect itself against
currency exchange rate fluctuations. There can be no assurance that fluctuations
in currency exchange rates in the future will not have a material adverse impact
on revenue from international sales and thus the Company's business, operating
results and financial condition. The Company may engage in hedging in the
future; however, there can be no assurance that any currency hedging policies
implemented by the Company in the future will be successful. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations" and
"Business - Sales and Marketing."

         Potential for Software Defects. Like other software products, the
Company's products have, on occasion, contained undetected errors, or "bugs,"
which become apparent through use of the product. Because the Company's new or
enhanced products are initially installed in a limited number of personal
computers and operated by a limited number of users, such errors may not be
detected for a number of months after delivery of the software. Significant
errors could result in the redeployment of Company personnel and funds to cure
the errors resulting in delays in product development and enhancements.
Moreover, software products with substantial errors could be rejected by
customers, which could have a material adverse effect on the Company's business,
results of operations or financial condition. Although the Company has not
experienced material adverse effects resulting from any such errors or defects
to date, there can be no assurance that errors or defects will not be discovered
in the future, potentially causing delays in product introduction and shipments
or requiring design modifications that could adversely affect the Company's
business, results of operations, or financial condition. It is also possible
that errors or defects in the Company's software products could give rise to
product liability or other liability claims. See "- Product Liability."

         Risks Associated with Proprietary Rights. The Company relies primarily
upon trade secret and copyright laws to protect its proprietary technology. The
Company enters into trade secret and confidentiality agreements with its
employees and also enters into confidentiality agreements with its distributors
and customers. Such confidentiality agreements typically limit access to, and
seek to prohibit decompilation and reverse engineering of the object code
embedded in the Company's AutoDE software products and other proprietary
software. The Company also typically uses a proprietary physical security device
developed by the Company and proprietary software to control the identity,
number of users and term of use of its AutoDE software products. The Company has
historically declined to seek patent protection for its AutoDE software products
because patents on such products would result in the public disclosure of
proprietary ideas and structures associated with its software. Further, the
Company generally has declined to seek copyright registration of its
copyrightable software since the registration process requires the disclosure of
certain portions of its source code and therefore increases the risk that a
competitor could use such copyright registrations to obtain sensitive
information regarding the Company's AutoDE software products. The Company has
applied for, and received U.S. trademark and service mark registrations on many
of the trademarks and service marks used in marketing its products and services.
There can be no assurance, however, that the steps taken by the Company to
protect its products and services under applicable intellectual property laws
and with the Company's proprietary control device are adequate to prevent
misappropriation of its technology or that the Company's competitors will not
independently develop technologies that are substantially equivalent or superior
to the Company's


                                     - 11 -
<PAGE>   16
technology. Further, it is very difficult to police unauthorized use of the
Company's products due to the nature of software. Any such misappropriation of
the Company's technology or development of competitive technologies could have a
material adverse impact on the Company's business, operating results and
financial condition. In addition, the laws of certain countries in which the
Company's products are distributed do not protect the Company's intellectual
property rights to the same extent as the laws of the United States. For
example, the laws of many foreign jurisdictions in which the Company licenses
its software products protects trademarks solely on the basis of the first to
register. The Company currently does not possess any trademark registrations in
foreign jurisdictions, although it does have copyright protection of its
software products under the provisions of various international conventions.
Accordingly, intellectual property protection of its products and services may
be ineffective in many foreign countries. In summary, there can be no assurance
that the protection provided by the laws of the United States or foreign
jurisdictions will be sufficient to protect the Company's intellectual property.

         The Company could incur substantial costs in protecting and enforcing
its intellectual property rights. Although there presently are no pending or
threatened intellectual property claims against the Company, third parties may,
in the future, assert patent, trademark, copyright and other intellectual
property right claims to technologies which are incorporated into the Company's
products. In such event, the Company may be required to incur significant costs
in reaching a resolution to the asserted claims. There can be no assurance that
such a resolution would not require that the Company pay damages or obtain a
license to the third party's intellectual property rights in order to continue
licensing the Company's products as currently offered or, if such a third party
license is required, that it would be available on terms acceptable to the
Company.

         Certain technology used in the Company's current products and products
under development include technology licensed from third parties. These licenses
generally require the Company to pay royalties and to fulfill confidentiality
obligations. The termination of any such licenses, or the failure of the third
party licensors to adequately maintain or update their products, could result in
delays in the Company's ability to ship certain of its products or in delays in
the introduction of the Company's new or enhanced products while it searches for
similar technology from alternative sources, if any, which would prove costly.
Any need to implement alternative technology could prove to be very expensive
for the Company and any delay in product introduction or shipment could result
in a material adverse effect on the business, result of operations and financial
condition of the Company. It may also be necessary or desirable in the future to
obtain additional licenses for use of third party products in the Company's
products and there can be no assurance that the Company will be able to do so on
commercially reasonable terms, if at all. See "Business - Proprietary Rights."

         Risks Attendant to Strategic Alliances or Acquisitions. The Company's
business strategy includes the possible acquisition of companies or technologies
or the entry into strategic alliances which will complement or supplement the
products and services sold by the Company. No assurance can be given that the
Company will be able to find attractive acquisition or strategic alliance
candidates, or that after completion of an acquisition or entry into an alliance
the Company will be able to effectively integrate the acquired operations or to
profitability manage such operations or strategic alliances. The failure to


                                     - 12 -
<PAGE>   17
complete acquisitions or enter into strategic alliances could have a material
adverse effect on the Company's ability to grow its revenues in the future.

         There are significant risks attendant to the Company's entry into
strategic alliances or the consummation of acquisitions. The Company has
recently entered into three strategic alliances and may enter into additional
strategic alliances in the future. Risks inherent in such current and any future
alliances include, among others, the inability to realize the intended benefits
of an alliance, the Company's increased reliance on third parties, the increased
payment of third party licensing fees or royalties for incorporation of third
party technology into the Company's products, the inadvertent transfer of the
Company's proprietary technology to a strategic "partner" and the opportunity
costs associated with entering into alliances. If any strategic alliance or
acquisition is consummated for cash and the Company borrows the required funds,
the Company may become highly leveraged, which could make it vulnerable to
increases in interest rates and extended economic downturns, limiting the
Company's flexibility in responding to changing economic and industry
conditions. If any strategic alliance or acquisition is financed by the issuance
of additional Common Stock or other convertible securities, such issuance may be
without stockholder approval and could dilute current stockholders and
stockholders who purchase shares of Common Stock in this Offering and may have a
negative impact on earnings per share and on the market price of the Common
Stock. There can be no assurance that the Company will be able to obtain
additional debt or equity financing on terms favorable to the Company, or at
all, or if obtained, there can be no assurance that such debt or equity
financing will be sufficient for the financing needs of the Company.

         Dependence on Management Personnel. The Company's future business
results depend in significant part on Herbert G. Blecker, the Company's Chairman
of the Board, President and Chief Executive Officer ("Mr. Blecker"), William F.
Geritz, III, the Company's Executive Vice President ("Mr. Geritz") and other
senior management and key employees, including certain engineering, managerial
and marketing personnel. The loss of the services of any of these individuals,
or groups of individuals, could have a material adverse effect on the Company's
business, operating results and financial condition. The Company has employment
agreements with Messrs. Blecker and Geritz that include non-competition
covenants. See "Management - Employment Agreements."

         Legal Proceedings. In 1979, the Company and Mr. Blecker were convicted
by a federal court for defrauding the General Services Administration ("GSA") by
making misstatements regarding Company employee qualifications in connection
with the performance of a subcontract for GSA, which resulted in overbilling the
GSA for such employees' services. The Company was fined $62,000 and Mr. Blecker
was sentenced to one year imprisonment, of which he served nine months. The GSA,
in 1983, sent a letter to the Company stating that the Company would be
permitted to continue to contract with the GSA. In addition, as a result of a
dispute with the Internal Revenue Service ("IRS") regarding a payment plan for
back taxes, the Company filed a voluntary petition under Chapter 11 of the U.S.
Bankruptcy Code in 1985 and emerged therefrom in 1988, making all payments
required pursuant to its plan of reorganization, the final payment being made in
1993. The Company believes that the foregoing described legal proceedings have
not had an adverse impact on the Company's recent business, financial condition
or results of operations. See "Business - Legal Proceedings - Prior Legal
Proceedings."

<PAGE>   18
         Year 2000 Compliance. Many currently installed computer systems and
software products are coded to accept only two-digit entries in the date code
field. Beginning in the year 2000, these date code fields will need to accept
four-digit entries to distinguish 21st century dates from 20th century dates. As
a result, computer systems and/or software used by many companies may need to be
upgraded to comply with such "year 2000" requirements. Significant uncertainty
exists in the software industry concerning the potential effects associated with
such compliance. Although the Company currently offers software products that
are either designed to be year 2000 compliant or have been, or are being or will
be upgraded to be year 2000 compliant, there can be no assurance that the
Company's software products contain all necessary date code changes. In
addition, the Company has warranted, and may in the future warrant, to certain
customers that its products will be year 2000 compliant, and the failure of such
products to be year 2000 compliant could have a material adverse effect on the
Company's business, financial condition or results of operations. Any failure of
the Company's products to be year 2000 compliant could result in a material
adverse effect on the Company's business, financial condition or results of
operations.

         Product Liability. The Company's license agreements with its customers
typically contain provisions designed to limit the Company's exposure to
potential product liability claims arising from a customer's use of the
Company's products. The Company does not guarantee that any particular result
will be obtained through the use of its AutoDE software, because the customer's
input variables typically control the results of the product's calculations. It
is possible, however, that the limitation of liability provisions contained in
the Company's license agreements may not be effective as a result of existing or
future federal, state or local laws or ordinances or unfavorable judicial
decisions. Although the Company has not experienced any product liability claims
to date, the sale and support of its software may entail the risk of such
claims, which could be substantial in light of the applications in which the
Company's products are used. A successful product liability claim brought
against the Company could have a material adverse effect upon the Company's
business, operating results and financial condition.

         Broad Management Discretion in Use of Proceeds. The net proceeds to the
Company from the sale of the Common Stock offered by the Company hereby at an
assumed initial public offering price of $8.00 per share (the midpoint of the
range as set forth on the cover page of this Prospectus) are estimated to be
$17.4 million, after deducting the estimated underwriting discount and Offering
expenses payable by the Company. Although the Company currently anticipates that
it will use a portion of such proceeds to further its strategic goals, the
remainder of such proceeds are currently allocated only for general corporate
purposes. Moreover, management will have the discretion to modify the use of net
proceeds, as described under the caption "Use of Proceeds." Consequently,
management will have broad discretion over the use of the net proceeds of the
Offering.

         Control by Principal Stockholders. Upon completion of the Offering, Mr.
Blecker, the Chairman of the Board and Chief Executive Officer, and his wife,
Eunice E. Blecker, the Company's Treasurer and Secretary (collectively, the
"Principal Stockholders"), will, in the aggregate, beneficially own
approximately 54.5% of the issued and outstanding shares of Common Stock of the
Company, and will therefore have the ability to effectively control the outcome
of all matters (including the election of directors, any merger or
consolidation, or the sale of all or substantially all of the Company's assets)
submitted to the stockholders for approval. This concentration of ownership may
also have the effect of delaying, deferring


                                     - 14 -
<PAGE>   19
or preventing a change in control of the Company and making certain
transactions more difficult or impossible absent the support of such
stockholders, including proxy contests, mergers involving the Company, tender
offers, open-market purchase programs or other purchases of Common Stock that
could give public, minority stockholders of the Company the opportunity to
realize a premium over the then-prevailing market price for shares of Common
Stock. See "Principal Stockholders."
                   
         Anti-Takeover Effects of the Company's Articles of Incorporation and
Maryland Law. The Company's Board of Directors has the authority to issue up to
5,000,000 shares of preferred stock, $.01 par value per share, of the Company
(the "Preferred Stock"), of which 100 shares of Series A Preferred Stock will be
outstanding following consummation of the Recapitalization, and to determine the
price, rights, preferences, privileges and restrictions of the unissued shares
thereof, including voting rights, without any further vote or action by the
Company's stockholders within certain limitations as prescribed by the rules of
the Nasdaq National Market. See "Description of Capital Stock." Moreover, the
Articles of Incorporation ("Articles") of the Company contain certain provisions
which, among other things, maintain a "staggered" Board of Directors, limit the
personal liability of, and provide indemnification for, the directors of the
Company, require that stockholders comply with certain requirements before they
can nominate someone for director or submit a proposal before a meeting of
stockholders, limit the ability of stockholders to call special meetings of
stockholders, limit the ability of stockholders to act by written consent and
require a supermajority of stockholders in the event that a "related person" (as
defined) attempts to engage in a business combination with the Company. See
"Description of Capital Stock -- Maryland Anti-Takeover Law and Certain
Provisions of the Articles of Incorporation."

         No Prior Public Trading Market. Prior to the Offering, there has been
no public trading market for shares of the Common Stock, and there can be no
assurance that an active public trading market will develop following
completion of the Offering or, if developed, that such market will be
sustained. The initial public offering price of the shares of Common Stock was
determined by negotiation between the Company and the Underwriters and will
not necessarily reflect the market price of the Common Stock following the
Offering. See "Underwriting" for a discussion of the factors considered in
determining the initial public offering price.
                                 
         Possible Volatility of Stock Price. The market price for the Common
Stock following the Offering will be affected by a number of factors, including
the announcement of new products, product enhancements or services by the
Company or its competitors, quarterly variations in the Company's results of
operations or results of operations of the Company's competitors, changes in
earnings estimates or recommendations by securities analysts, developments in
the Company's industry and in the process manufacturing segments of various
industries, general market and economic conditions and other factors, including
factors unrelated to the operating performance of the Company or its
competitors. In addition, stock prices for many companies in the technology and
emerging growth sectors have experienced wide fluctuations which have often been
unrelated to the operating performance of such companies. Such factors and
fluctuations may adversely affect the market price of the Company's Common
Stock.

         Shares Eligible for Future Sale. Sales of a substantial number of
shares of Common Stock in the public market following the Offering could
adversely affect the market price


                                     - 15 -
<PAGE>   20
of the Common Stock prevailing from time to time. Upon completion of this
Offering, the Company will have 5,500,000 shares of Common Stock outstanding. Of
these outstanding shares, the 2,500,000 shares sold in this Offering will be
freely transferable without restriction or further registration under the
Securities Act of 1933, as amended (the "Securities Act"), unless they are held
by "affiliates" of the Company within the meaning of Rule 144 promulgated under
the Securities Act ("Rule 144") as currently in effect. The remaining 3,000,000
shares held by existing stockholders will be "control shares" within the meaning
of Rule 144 and may not be sold in the absence of registration under the
Securities Act or pursuant to an exemption from registration under Rule 144
promulgated under the Securities Act.

         The Company and each of the Principal Stockholders of the Company have
entered into lock-up agreements providing that neither the Company nor any
Principal Stockholder will offer, sell, pledge, grant an option for the sale of
or otherwise dispose of shares of Common Stock, or any interest therein, or any
securities exercisable for or convertible into shares of Common Stock, for a
period of 180 days after the effective date of the offering made hereby (until
______ __, 1998) without the prior written consent of Hoak Breedlove Wesneski &
Co. Any shares subject to these lock-up agreements may be released at any time
by Hoak Breedlove Wesneski & Co.

         As of the date of this Prospectus, the Company has reserved an
aggregate of 760,500 shares of Common Stock for issuance pursuant to the Stock
Option Plan and options to purchase 437,400 shares will be outstanding under the
Stock Option Plan immediately prior to the commencement of the Offering. Such
options will vest at a rate of 20% per year on each annual anniversary of the
date on which the option was granted. The Company also has reserved 507,000
shares for issuance under the Recognition Plan, none of which are anticipated to
be granted immediately following the consummation of the Offering. As soon as
practicable following the Offering, the Company intends to file registration
statements on Form S-8 under the Securities Act to register shares of Common
Stock reserved for issuance under such plans. Such registration statements will
automatically become effective immediately upon filing. See "Shares Eligible for
Future Sale."

         Substantial Dilution. Purchasers of Common Stock offered hereby will
suffer an immediate and substantial dilution of $4.56 per share in net tangible
book value per share of the Common Stock. See "Dilution."

                                 USE OF PROCEEDS


         The net proceeds to the Company from the sale of the shares of Common
Stock offered by the Company hereby at an assumed initial public offering price
of $8.00 per share are estimated to be $17.4 million, after deducting the
estimated underwriting discount and Offering expenses payable by the Company
(or approximately $20.1 million if the Underwriters' over-allotment option is
exercised in full). 

         The Company intends to use the net proceeds to further its strategic
goals as described herein, and therefore expects to utilize a portion of the net
proceeds to accelerate its development of complementary AutoDE software
products, to expand its engineering and direct sales and marketing force, for
current or possible future strategic alliances, for the possible acquisition of
complementary technologies or companies, and for general corporate purposes. See
"Business - Strategy."

         Company management continually evaluates the manner in which it can
most effectively bring new products or product enhancements to market and,
accordingly, reviews on a constant basis whether it is more efficacious to
develop internally or acquire (by purchase, license or alliance) certain
technologies. As a consequence, the amount of net proceeds to be devoted to
furthering a given element of the Company's strategic plan, such as internal
product development, may be re-directed towards furthering one or more other
elements of the Company's strategic plan, such as possibly entering into
strategic alliances or undertaking acquisitions. Accordingly, the net proceeds
which may be used for a particular purpose may be subject to change based on
future events which cannot be accurately predicted. Moreover, the Company
intends to maintain its flexibility to use the net proceeds to respond to other
business opportunities in the engineering software and software services
industry in the future. Consequently, management will have broad discretion over
the use of the proceeds in this Offering. See "Risk Factors - Broad Management
Discretion in Use of Proceeds."

         The Company continues to evaluate potential strategic alliances and
potential acquisitions and to identify and have preliminary discussions with
potential strategic alliance and/or acquisition candidates, although there are,
as of the date of this Prospectus, no agreements, arrangements or understandings
between the Company and any party relating thereto. There can be no assurance
that any strategic alliance or acquisition can or will be consummated on terms
favorable to the Company, or at all. See "Risk Factors-Risks Attendant to
Strategic Alliances or Acquisitions" and "Business -Strategy."

         Pending the uses described above, the Company will invest the net
proceeds from the sale of the Common Stock offered by it hereby in short-term,
investment grade, interest-bearing securities.

                                 DIVIDEND POLICY

         The Company has not declared or paid any cash dividends on the Common
Stock and does not presently intend to pay cash dividends on the Common Stock in
the foreseeable future. Any payment of cash dividends on shares of Common Stock
will be within the discretion of the Company's Board of Directors and will
depend upon the earnings of the Company, the Company's capital requirements,
restrictions imposed by the Company's lenders, if any, applicable requirements
of the Maryland General Corporation Law ("MGCL") and other factors considered
relevant by the Company's Board of Directors.

                                    DILUTION


         At October 31, 1997, the unaudited net tangible book value of the
Company was $994,000 or $0.33 per share of Common Stock outstanding. The net
tangible book value per share represents the amount of total assets (excluding
intangible assets) less total liabilities, divided by the total number of shares
of Common Stock outstanding. At October 31, 1997, after having given effect to
the sale of 2,500,000 shares of the Common Stock in the Offering by the Company
at an assumed initial public offering price of $8.00 per share and after
deduction of estimated underwriting discounts and Offering expenses payable by
the Company, the pro forma net tangible book value of the Company would have
been $18.9 million or $3.44 per share. This represents an immediate increase in
pro forma net tangible book value of $3.11 per share to existing stockholders
and an immediate dilution in pro forma net tangible book value of $4.56 per
share to the new investors purchasing shares of Common Stock in this Offering.
The following table illustrates this per share dilution:

        of this Offering, there will be outstanding options to purchase 437,400
        shares of Common Stock with an exercise price equal to the initial
        public offering price, which options will vest and become exercisable at
        the rate of 20% per year in 1999 through 2003. It is also anticipated
        that options to purchase shares will be issued to non-employee directors
        immediately after the Company's 1998 annual meeting of stockholders and
        that no shares will be granted under the Recognition Plan immediately
        following the Offering. See "Management - Stock Plans - 1998 Stock

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

         The following discussion and analysis should be read in conjunction
with "Selected Consolidated Financial Data" and the Company's consolidated
financial statements and notes thereto included elsewhere in this Prospectus.
The discussion in this Prospectus contains certain forward-looking statements
that involve risks and uncertainties, such as statements of the Company's plans,
objectives, expectations and intentions. The cautionary statements made in this
Prospectus should be read as being applicable to all related forward-looking
statements wherever they appear in this Prospectus. While the forward-looking
statements reflect the Company's good faith beliefs, they are not guarantees of
future performance and involve known and unknown risks and uncertainties. The
Company's actual results could differ materially from those discussed here. Some
of the factors that could cause or contribute to such differences include those
discussed in "Risk Factors," as well as those discussed elsewhere herein.

OVERVIEW

         The Company was organized in 1969 to develop and market engineering
services to the process manufacturing segments of the chemical, petroleum
refining and other industries. During this period, the Company developed a cost
estimation software product to be run on the mainframe computers of certain of
its large customers. In 1970, the Company shipped its first commercial cost
estimation software program, the COST System. With the proliferation of powerful
desktop computers and easy-to-use operating systems like Windows in the early
1990s, the Company shifted direction to focus on the development of AutoDE
software products. In fiscal 1993, the Company released the first of a series of
Windows-based AutoDE products.

         The Company derives its revenue primarily from the sale of licenses of
its AutoDE software products, and, to a lesser extent, from maintenance fee and
other revenue. Revenue from software licenses accounted for 75.6% and 70.4% of
the Company's total revenues for the six months ended October 31, 1997 and for
fiscal 1997, respectively. Maintenance fee, training, consulting and other
services accounted for 24.4% and 29.6% of the Company's revenues for the six
months ended October 31, 1997 and for fiscal 1997, respectively.

         The Company typically licenses its AutoDE software to customers on a
per-authorized user basis for a one or multi-year term. The license fee for a
one-year license for a single U.S. user of one of the Company's core AutoDE
software products ranges from $7,900 to $31,500, depending on the product and
license term. The license fee charged by the Company per authorized user
declines as the customer increases the total number of authorized users and
increases the commitment term of the license.

         Customers who license software products from the Company under
multi-year agreements have the option of paying the applicable license fee in
full at the beginning of the term of the license or making annual payments
throughout the term of the license. A substantial majority of customers who have
multi-year agreements elect the annual payment option. The Company believes that
this election is principally because the customers prefer to pay for the
Company's AutoDE software products out of their operating budgets. Customers who
elect to pay throughout the term of the license are required to pay


                                     - 23 -
<PAGE>   28
additional annual charges based upon increases in the Consumer Price Index in
the United States, the Retail Price Index in the United Kingdom, the Consumer
Price Index in Japan, the United Kingdom Retail Price Index in the European
Union, and the United States Consumer Price Index elsewhere, depending upon the
location of the Company's billing office.

         The following table sets forth the license terms remaining at October
31, 1997 for all licenses in effect on that date:

*        Does not include 4 older licenses which permit an unlimited number of
         users, nor does it include 7 multi-year term licenses that have been
         prepaid.

         The Company believes that its ability to sell a substantial number of
multi-year term licenses, as demonstrated by the above table, is an important
historical financial strength. For the twelve-month period ended October 31,
1997, 68.5% of licensed authorized users whose licenses expired during such
period elected to renew such licenses (including renewals that involved the
substitution of another ICARUS product), and 49.1% of all new licenses sold to
authorized users were for a term of two or more years. The Company is highly
dependent upon license renewal revenues. See "Risk Factors - Dependence on
Contract Renewals."

         One of the Company's strategic alternatives is to enter into technology
licensing arrangements or strategic alliances to more quickly bring to market
new AutoDE software products or product enhancements by combining its technology
with the technology of its strategic "partners." Management of the Company
believes that any revenue generated as a result of such licensing or alliance
arrangements will be partially offset by increased costs of software license
revenue due to the more significant royalty or license fee obligations of the
Company arising out of such arrangements. In addition, the Company also expects
that it will have certain higher expenses in near-term future periods, as it
recently increased the level of its expenses associated with product development
and sales, with no certainty that the incurrence of such expenses will result in
future revenues.

         The Company recognizes revenue from product licensing agreements in
accordance with the American Institute of Certified Public Accountants Statement
of Position No. 91-1, "Software Revenue Recognition" ("SOP 91-1"). Revenue from
software license agreements is recognized upon execution of a contract and
shipment of the software, provided that no significant vendor obligations remain
and collection is probable. Upon renewal of one-year licenses, revenue is
recognized on the contract renewal date. For multi-year agreements,


                                     - 24 -
<PAGE>   29
revenue is recognized ratably over the multi-year period on each successive
anniversary date. Any amount billed in advance of satisfying the above revenue
recognition criteria is classified as current and long-term deferred revenue.
Maintenance revenue is recognized ratably over the support period, which is
generally one year. Such revenue includes amounts bundled with the initial
license fee arrangement for which separate prices have been derived for
financial reporting purposes based upon the Company's historical retail pricing
for separate arrangements. Consulting and training revenue is recognized as the
related services are performed. See Note A of Notes to Consolidated Financial
Statements.

         The American Institute of Certified Public Accountants has released
Statement of Position No. 97-2 "Software Revenue Recognition" ("SOP 97-2"),
which supersedes SOP 91-1. The new SOP 97-2 will be effective for all
transactions entered into by the Company in fiscal year 1999. The new SOP 97-2
requires, among other things, that revenue should be recognized when there is
persuasive evidence of an existing arrangement, delivery has occurred, the fees
charged are fixed or determinable and collectibility is probable. Additionally,
SOP 97-2 provides that for those arrangements which consist of multiple elements
such as upgrades, enhancements and post-contract support, the fees charged must
be allocated to each element of the arrangement based upon vendor-specific
objective evidence of fair value, which is limited to a price charged when the
element is sold separately or the price for the element is established by
management. The Company currently recognizes revenue on license agreements when
all of the conditions described above have been met, and revenue on multi-year
license agreements typically is not recognized until such time that payments
from customers become due (i.e., the license anniversary date). Additionally,
the Company has allocated fees between elements of its arrangements based upon
established prices charged for those elements when sold separately. In
management's opinion, the impact of SOP 97-2 is not expected to be material.

         Software development costs relating to new software products and
enhancements to existing software products are expensed as incurred until
technological feasibility has been established, after which additional costs are
capitalized in accordance with Financial Accounting Standards Board Statement
No. 86, "Accounting for the Costs of Computer Software to Be Sold, Leased or
Otherwise Marketed." Historically, the Company has not incurred material
software development costs following the establishment of technological
feasibility, and therefore no costs for software development have been
capitalized for the six months ended October 31, 1997 or for fiscal years 1997,
1996 or 1995.

</TABLE>


SIX MONTHS ENDED OCTOBER 31, 1997 COMPARED TO SIX MONTHS ENDED OCTOBER 31, 1996

         Total Revenue. Total revenue for the six months ended October 31, 1997
increased by $698,000 or 19.6% to $4.3 million from $3.6 million for the six
months ended October 31, 1996. Software license revenue consists of fees paid by
the Company's customers to license its AutoDE software under single or
multi-year arrangements. Software license revenue increased 30.2% from $2.5
million for the six months ended October 31, 1996 to $3.2 million for the six
months ended October 31, 1997. The increase in software license revenue for the
six-month period in fiscal 1998 as compared to the six-month period in fiscal
1997 was primarily due to renewals of software licenses, the addition of new
users by existing customers, the sale of new products developed in fiscal 1996
to existing customers and the sale of new and existing products to new
customers. Maintenance fee and other revenue consists of maintenance fee,
training, consulting services and other revenue. Maintenance fee and other
revenue decreased 4.5% from $1.1 million for the six months ended October 31,
1996 to $1.0 million for the six months ended October 31, 1997. The decrease was
primarily attributable to a reduction in the number of on-site training courses
conducted by the Company during this period due to a temporary reduction in the
Company's staff dedicated to training.

         Cost of Software License Revenue. Cost of software license revenue
consists of costs related to delivery of software (including disk duplication
and system control device costs),


                                     - 26 -
<PAGE>   31
printing of manuals and packaging, and commissions, royalties and license fees
paid to third parties. Cost of software license revenue was $607,000 and
$419,000 for the six months ended October 31, 1997 and 1996, respectively.
Expressed as a percentage of software license revenue, cost of software license
revenue was 18.9% and 17.0% in the six-month periods of fiscal years 1998 and
1997, respectively. The increase in the cost of software license revenue is
largely attributable to increased labor costs associated with product releases,
independent sales representatives' commission expenses as well as increased
duplication expenses.

         Cost of Maintenance Fee and Other Revenue. Cost of maintenance fee and
other revenue consists primarily of technical support, training, consulting and
facility costs as well as other contract costs. Cost of maintenance fee and
other revenue was $286,000 and $248,000 for the six months ended October 31,
1997 and 1996, respectively. Expressed as a percentage of maintenance fee and
other revenue, the cost of maintenance fee and other revenue was 27.5% and 22.8%
for the six months ended October 31, 1997 and 1996, respectively.

         Selling and Marketing. Selling and marketing expense consists primarily
of personnel costs related to sales and marketing, including occupancy, travel,
entertainment, telephone, promotional, trade show expenses and direct sales
force commissions. Selling and marketing expense was $1.4 million and $1.2
million in the six months ended October 31, 1997 and 1996, respectively. Selling
and marketing expense as a percentage of total revenue was 33.5% and 33.3% for
the six months ended October 31, 1997 and 1996, respectively. The increase in
selling and marketing expense during the six-month period in fiscal 1998, as
compared to the same period in fiscal 1997, was chiefly the result of the
expansion of the Company's direct sales force and increases in the Company's
participation in exhibitions and related expenses.

         Research and Development. Research and development expense consists
principally of personnel, equipment and facility costs incurred in the research,
design, development and refinement of the Company's products. Research and
development expense was $511,000 in the first six months of fiscal 1998 as
compared to $400,000 for the same period in fiscal 1997. Research and
development expense as a percentage of total revenue was 12.0% and 11.2% for the
first six months of fiscal 1998 and 1997, respectively. The increase reflects
the Company's continued commitment and investment in the research and
development of new AutoDE software products.

         General and Administrative. General and administrative expense consists
principally of personnel costs for corporate administration, in addition to
accounting and legal services, depreciation, equipment and facility costs, and
general management expenses of the Company. General and administrative costs
were $918,000 and $741,000 for the six months ended October 31, 1997 and 1996,
respectively. General and administrative expense as a percentage of total
revenue was 21.6% and 20.7% for the six months ended October 31, 1997 and 1996,
respectively. The increase in general and administrative expense was chiefly
attributable to the establishment of a reserve, totaling approximately $110,000,
for a potential claim against the Company by a former employee, the opening of
the Company's Houston, Texas office, the hiring of the Company's Chief Financial
Officer and an increase in administrative payroll and related expenses.

         Interest Income, net. Interest income, net increased $36,000 from
$13,000 for the six months ended October 31, 1996 to $49,000 for the same period
in 1997 because of larger cash balances on deposit.

         Provision (Benefit) for Income Taxes. The Company's effective tax rate
was 38.5% and 39.5% for the six months ended October 31, 1997 and 1996,
respectively.

YEAR ENDED APRIL 30, 1997 COMPARED TO YEAR ENDED APRIL 30, 1996

         Total Revenue. Total revenue increased $1.6 million or 29.2% from $5.7
million in fiscal 1996 to $7.3 million in fiscal 1997. Software license revenue
increased to $5.2 million in fiscal 1997 from $3.8 million in fiscal 1996,
representing an increase of 35.5%. The increase in software license revenue in
fiscal 1997 as compared to fiscal 1996 was primarily due to renewals of software
licenses, the addition of new users, and the sale of new products to existing
customers resulting from a promotional campaign which commenced late in the
third quarter of 1997 and continued through the fourth quarter of 1997, and to a
lesser extent, sales associated with the creation of the Company's Tokyo office
in December 1995. Maintenance fee and other revenue increased by $308,000 or
16.5% from $1.9 million in fiscal 1996 to $2.2 million in fiscal 1997. The
increase was largely the result of increases in training and maintenance fees
associated with increased license sales and increased training, partially offset
by reductions in consulting and other services.

         Cost of Software License Revenue. Costs of software license revenue was
$871,000 and $562,000 in fiscal years 1997 and 1996, respectively. Expressed as
a percentage of software license revenue, cost of software license revenue was
16.9% and 14.7% in fiscal years 1997 and 1996, respectively.

         Cost of Maintenance Fee and Other Revenue. Cost of maintenance fee and
other revenue was $520,000 and $537,000 in fiscal years 1997 and 1996,
respectively. Expressed as a percentage of maintenance fee and other revenue,
cost of maintenance fee and other revenue was 23.9% and 28.8% in fiscal years
1997 and 1996, respectively. Cost of maintenance fee and other revenue decreased
from fiscal years 1996 to 1997 due to a decrease in third party hardware
expenses.

         Selling and Marketing. Selling and marketing expense was $2.5 million
and $2.2 million in fiscal years 1997 and 1996, respectively. However, as a
percentage of total revenues, selling and marketing expense was 33.7% and 38.3%
in fiscal years 1997 and 1996, respectively. The increase in actual expense in
fiscal 1997 from fiscal 1996 was primarily the result of new sales and marketing
activity associated with the opening of the Company's new Tokyo office in
December 1995, the expansion of the Company's direct sales force, both
nationally and internationally, and increases in telephone, travel and
commission expenses.

         Research and Development. Research and development expense was $904,000
and $850,000 in fiscal years 1997 and 1996, respectively. However, research and
development expense as a percentage of revenue was 12.3% and 15.0% in fiscal
years 1997 and 1996, respectively. The increase in actual expense reflects the
Company's continued commitment and investment in the research and development of
new AutoDE software products.


                                     - 28 -
<PAGE>   33
         General and Administrative. General and administrative costs were $1.5
million and $1.3 million in fiscal years 1997 and 1996, respectively. However,
general and administrative expense as a percentage of revenue was 21.0% and
22.4% in fiscal years 1997 and 1996, respectively. The increase in actual
expense is largely attributable to the formation of the Company's Tokyo office
in December 1995, the hiring of the Company's Chief Financial Officer, and to a
lesser degree increases in legal, accounting and temporary staff in preparation
for the Offering, and foreign exchange losses, which were partially offset by a
decline in equipment costs.

         Interest Income, net. Interest income, net increased $24,000 from
$21,000 in fiscal 1996 to $45,000 in fiscal 1997.

         Provision (Benefit) for Income Taxes. The Company's effective tax rate
was 38.9% and 36.5% in fiscal years 1997 and 1996, respectively.

YEAR ENDED APRIL 30, 1996 COMPARED TO YEAR ENDED APRIL 30, 1995

         Total Revenue. Total revenue increased 12.3% to $5.7 million in fiscal
1996 from fiscal 1995. Software license revenue increased 20.4% from fiscal 1995
to $3.8 million in fiscal 1996. The increase in software license revenue from
fiscal 1995 to fiscal 1996 was primarily due to the introduction of new products
in the first quarter of fiscal 1996, as well as the addition of new users by
existing customers, which was partially offset by a slight decline in the sales
of other products. Maintenance fee and other revenue remained constant at $1.9
million in fiscal 1996 and fiscal 1995.

         Cost of Software License Revenue. Cost of software license revenue
increased 10.9% from fiscal 1995 to $562,000 in fiscal 1996 and represented
14.7% of software license revenue in fiscal 1996. Cost of software license
revenue increased over the prior year primarily due to higher third party
software and Control Device costs.

         Cost of Maintenance Fee and Other Revenue. Cost of maintenance fee and
other revenue increased $215,000 or 66.8%, to $537,000 and represented 28.8% of
maintenance fee revenue in fiscal 1996. Of this increase, $125,000 was the
result of an increase in the cost of hardware sold to customers using ICARUS
products. Additionally, $76,000 of this increase was a result of the increased
staffing required to support additional training classes offered by the Company.

         Selling and Marketing. Selling and marketing expense increased 30.6%
from fiscal 1995 to $2.2 million or 38.3% of revenue in fiscal 1996. The
increase in selling and marketing expense in fiscal 1996 from fiscal 1995 was
generally attributable to the expansion of the Company's marketing efforts.

         Research and Development. Research and development expense increased
1.1% from fiscal 1995 to $850,000 or 15.0% of total revenue in fiscal 1996.

         General and Administrative. General and administrative costs increased
4.3% from fiscal 1995 to $1.3 million or 22.4% of revenue in fiscal 1996. The
increase was generally attributable to increases in depreciation, insurance
expense and office supplies.

         Interest Income, net. Interest income, net increased $13,000 from
fiscal 1995 to $21,000 in fiscal 1996.

         Provision (Benefit) for Income Taxes. The Company's effective tax rate
was 36.5% and 40.4% in fiscal years 1996 and 1995, respectively.

SELECTED QUARTERLY OPERATING RESULTS

         The Company ships software products within a short period after receipt
of an order and typically does not have a material backlog of unfilled orders.
Total revenue in any quarter is dependent (and will become substantially
dependent to the extent the Company increases the number of contracts for new
and renewing customers that result in the recognition of license revenue upon
shipment) on orders booked and license renewals in that quarter and are not
predictable with any degree of certainty.

         The Company's operating results have fluctuated in the past and may in
the future fluctuate significantly from quarter to quarter or on an annual basis
as a result of a number of factors, including, but not limited to: the size and
timing of customer orders; changes in license renewal rates, delays in renewals,
or failure of existing customers to renew their licenses with the Company when
their current licenses expire; the length of the Company's sales cycle; changes
in contract terms (including terms affecting the timing of recognition of
license revenue); success of the Company's service offerings; timing of new
product announcements and introductions by the Company and its competitors; the
Company's ability to develop, introduce and market new products and product
enhancements; market acceptance of the Company's products; deferrals of customer
orders in anticipation of new products or product features; the Company's
ability to control general and administrative costs; changes in the Company's
management team; and fluctuating economic conditions; and political instability
in, or trade embargoes with respect to, foreign markets. The Company's future
operating results may fluctuate as a result of these and other factors, which
could have a material adverse effect on the Company's business, operating
results and financial condition. See "Risk Factors - Fluctuations in Future
Operating Results."

         The following tables set forth selected quarterly statement of
operations data in dollars and as a percent of total revenue for fiscal 1997 and

(1)      Total operating expenses were higher on an absolute basis and as a
         percentage of total revenue during the second quarter of fiscal 1998 on
         a comparative basis to the other quarters presented due primarily to
         increased personnel and related benefit costs. During the second
         quarter of fiscal 1998, increased selling and marketing expenses
         reflect the hiring of additional sales and marketing personnel and an
         increase in overall marketing and business development efforts. Also,
         during this quarter, increased research and development expenses
         reflect the addition of five new research and development employees,
         one new technical support employee and related recruitment fees.

LIQUIDITY AND CAPITAL RESOURCES

         During the six-month period ended October 31, 1997 and fiscal years
1997 and 1996, the Company satisfied its cash needs through cash provided by
operations. Cash provided by operating activities during the six months ended
October 31, 1997 and fiscal years 1997 and 1996 was approximately $648,000, $1.2
million and $519,000, respectively. At October 31, 1997 and at April 30, 1997
and 1996, the Company had working capital of $1.1 million, $1.1 million and
$496,000, respectively. The ratio of current assets to current liabilities at
October 31, 1997 and at April 30, 1997 and 1996 was 1.34 to 1, 1.39 to 1 and
1.25 to 1, respectively. The Company currently does not maintain a credit
facility.


                                     - 32 -
<PAGE>   37
         Cash used in investing activities has been for the purchase of property
and equipment which amounted to $158,000, $250,000 and $215,000 for the six
months ended October 31, 1997 and in fiscal years 1997 and 1996, respectively.

         Cash used in financing activities for the six months ended October 31,
1997 and during fiscal years 1997 and 1996 was $1,000, $107,000 and $0,
respectively. Cash used in financing activities for the six months ended October
31, 1997 was for payments on a capital lease obligation. Cash used in financing
activities for fiscal 1997 was primarily for the repayment of two shareholder
notes that were issued in April 1992, in the aggregate amount of $125,000, with
interest at 6.5% annually. Such notes were repaid in full in January 1997.

         The Company believes that the net proceeds from this Offering, existing
cash resources and cash flow from operations will be sufficient to fund the
Company's operations for at least the next twelve months. See "Use of Proceeds"
for more information regarding possible capital requirements with respect to the
Company's strategic goals.

INFLATION

         Because many license agreements require an adjustment tied to certain
consumer or retail price indices, inflation has not had a significant impact on
the Company's operating results to date. The Company does not expect inflation
to have a significant impact on its results of operations during fiscal 1998.

                                    BUSINESS

THE COMPANY

         ICARUS develops automated desktop engineering software for the process
manufacturing segments of the chemical, petroleum refining, pulp and paper,
food and other industries. The Company's 300-plus customers are primarily
large, multinational corporations that own and operate process manufacturing
plants (the "owner-operators") or primarily multinational engineering and
construction companies that provide services to owner-operators (the "E&C
companies"). The Company's customers include such companies as Mitsubishi
Chemical Corporation, Shell Oil Company, The Mead Corporation, Campbell Soup
Company and Fluor Daniel, Inc.

         The Company's integrated AutoDE software products are widely used in
the chemical and petroleum refining industries. One or more of the Company's
products are licensed to 18 of the top 20 chemical companies and 18 of the top
20 petroleum refining companies, as such companies are listed in the "1997
Fortune 500 List," and 8 of the top 10 chemical plant contractors listed in
Engineering News Record's "Top 400 Contractors." Near-term growth opportunities
for the Company include the introduction of new AutoDE products to the
Company's current customers and to potential customers in the chemical and
petroleum refining industries, further penetration by existing and new products
in other industries, including the pharmaceutical, paper and pulp, food and
power industries, and continued expansion in international markets. 

         The Company's current software products automate important steps in the
"decision engineering" process through which a customer's engineering staff
evaluates the technological and economic feasibility of the construction or
modification of a process manufacturing plant and senior executives determine
whether to proceed with a proposed project. Despite the importance of this
decision, which may involve a capital investment in excess of one billion
dollars, these executives usually have only a limited ability to manage the
conventional decision engineering process, which is time-consuming,
labor-intensive, imprecise and expensive.

         The Company's current products directly address a number of the
deficiencies in the conventional decision engineering process by
"re-engineering" the process to take full advantage of today's desktop computing
technology. The Company's products enable engineers to simulate, model and
analyze the design, cost and time requirements of a proposed project more
quickly and less expensively than they can using conventional engineering
methods. ICARUS products also enhance senior executives' ability to focus the
decision engineering process on business priorities. With more timely and
accurate information that integrates business considerations with sophisticated
engineering analysis, senior executives can make faster, better informed and
more confident decisions. Benefits arising from the use of the Company's
decision engineering software products include more effective strategic
planning, faster reaction to market developments and improved plant operating
efficiency, all of which enhance the customer's competitive position.

         In addition to the Company's decision engineering products, other
AutoDE software products automate important steps in the "plant engineering"
process, which occurs after the


                                     - 34 -

decision to proceed with a project has been made. These products also facilitate
construction scheduling and cost estimation for smaller projects at existing
plants.

THE PROCESS MANUFACTURING BUSINESS

         Process manufacturing of products in bulk quantities is performed in
the chemical, petroleum refining, pharmaceutical, pulp and paper, metal and
mineral, food, consumer product, power and other industries. Through chemical
reaction, combustion, mixing, separation, heating, cooling and other operations,
process manufacturing plants process raw materials (e.g., separate oil and gas
from other substances), refine those materials (e.g., extract propylene from oil
and gas feedstocks), produce intermediate products (e.g., synthesize nylon from
propylene) and manufacture finished products. Using data provided by industry
sources, the Company estimates that total worldwide process manufacturing annual
revenues exceed $3 trillion. Industry sources also indicate that more than
15,000 process manufacturing plants are now in operation worldwide and that
global spending on process manufacturing plant construction projects will exceed
$160 billion in 1998--an all-time high.

         On a regular basis, owner-operators consider proposals to build or
modify process manufacturing plants. The Company believes that hundreds of
proposed process manufacturing projects are evaluated for every project actually
built. In evaluating the potential return-on-investment of project proposals,
owner-operators face three basic facts: First, the construction or modification
of a plant requires a substantial capital investment. A world-class petroleum
refining complex, for example, can cost in excess of one billion dollars.
Second, heightened global competition has reduced both profit margins and the
acceptable margin for error in project evaluation. Third, increasingly efficient
global capital markets will penalize an owner-operator, particularly a public
owner-operator, for allocating capital to a project that does not produce
satisfactory returns.

         An E&C company faces an equally challenging business environment.
First, the E&C company must expend thousands of engineering man-hours on
competitive bid proposals. If the company does not win the bid, the man-hours
invested are lost. Second, the E&C company is under increasing pressure to
prepare more bid proposals without expanding their engineering staffs. Third,
the increasing use of lump-sum, turnkey project contracts has shifted much of
the financial risk of cost overruns, construction delays and performance
shortfalls from the owner-operator to the E&C company. Inaccurate bids or
improperly prepared proposals can result in multi-million dollar losses and
seriously damage the reputation of the E&C company.

THE DECISION ENGINEERING PROCESS

         The conventional decision engineering process typically begins with a
senior business development executive at a major owner-operator, who has been
assigned the task of determining which of several market opportunities the
owner-operator should pursue. Building a plant to pursue a given opportunity may
involve a commitment of hundreds of millions or more than one billion dollars,
and the full impact of that capital investment decision may not be apparent for
years. To answer business-critical questions on a proposed project's scope,
cost, timing and return, the executive turns to his internal engineering staff
for assistance.


                                     - 35 -
<PAGE>   40
         In response to the senior executive's request, process engineers first
perform process simulation and create conceptual mechanical process design
alternatives. With these alternatives in hand, they select the core process
equipment, (e.g., distillation towers, compressors, etc.) and produce CAD and
CAE drawings, such as block diagrams, process flow diagrams and piping and
instrumentation diagrams. With the assistance of engineers from various
disciplines (such as mechanical, structural, civil and electrical engineering),
a conceptual mechanical project design is completed.

         Once this design is complete, engineers calculate the quantities of
pipe, steel, instrumentation, process control, electrical fixtures, wiring,
paint, insulation, etc., necessary to build the project. Then, they research
cost information for alternative geographical locations and determine the number
of construction man-hours that will be required to install, lift, weld, connect
and construct each component of the project. A team of engineers then takes this
information and creates a critical-path-method schedule that outlines the tasks
necessary to complete the project on time and within budget. Finally, after the
evaluation of several different scenarios, a detailed decision engineering
report incorporating the conceptual mechanical design of the proposed project
together with cost estimates, preliminary engineering drawings and a preliminary
construction schedule is presented to the executive for review.

         At this stage, project specifications are often modified, and the
decision engineering process must be repeated. A single change in one aspect of
the project may affect a multitude of engineering calculations. For example,
enlarging a pump will require a larger electrical motor and larger diameter
piping and conduit, which in turn will require a larger pump foundation, etc.
An apparently minor modification can thus result in substantially greater costs,
and despite the expense and delay, the decision engineering process must attempt
to identify the full impact of such modifications. Otherwise, the risk of cost
overruns, construction delays and/or performance shortfalls may be greatly
increased.

         If the project sustains the executive's initial review, internal
engineering and financial reports are sent to several E&C companies, which then
perform their own, albeit more detailed, decision engineering process to produce
engineering, procurement and construction proposals. Ultimately, they present
their proposals to the owner-operator, which will then compare its internally
developed return-on-investment analysis with the E&C companies' proposals. If
the owner-operator decides to proceed, it may ask the E&C companies to prepare
lump-sum ("cost not to exceed") or other types of bids. Then, the owner-operator
and certain selected E&C companies may engage in negotiations involving the
basis for the bid request and the bids. After the owner-operator selects a final
E&C company, further efforts are expended to fine-tune the decision engineering
analysis during the design phase of the project.

         Even when significant resources are expended in conventional decision
engineering to develop detailed preliminary concepts to assist senior executive
decision-making, the final outcome may bear little resemblance to the initial
concept. This variance largely can be attributed to deficiencies in the
conventional process, which has not been comprehensively updated to take
advantage of new technology. These deficiencies include:

- -        Coordination Between Business Development and Engineering Is Limited.
         Senior business development executives in owner-operators and E&C
         companies usually find


                                     - 36 -
<PAGE>   41
         it difficult to manage their internal engineering staffs to ensure that
         business priorities are driving engineering considerations, rather than
         the reverse. Senior executives generally do not have the management
         tools needed to dynamically guide and direct the decision engineering
         process. As a result, substantial time and resources can be wasted on
         engineering issues that are not pertinent to a senior executive's
         decision-making analysis, and pertinent issues can be overlooked or
         under-analyzed.

- -        Dependence on Unreliable, Inconsistent or Unavailable Data Sources.
         Each engineering team usually develops its own specialized database of
         design and cost data, which may be unreliable or involve the use of
         assumptions. Developing and maintaining a specialized database
         requires labor-intensive research using multiple internal and external
         data sources of varying reliability that may be inconsistent with one
         another or with data collected by other teams. In some situations,
         reliable data is simply unavailable, and the team must make
         assumptions to fill the gap in available data.

- -        Time-Consuming, Calculation-Intensive Data Manipulation Is Required. In
         addition to the laborious data entry efforts required to develop
         specialized databases, each engineering team must perform
         time-consuming, calculation-intensive data manipulation in its
         simulation, modeling and analysis efforts. Industry sources indicate
         that 50% to 80% of a process design engineer's time is spent moving and
         organizing, rather than analyzing, data.

- -        Engineering Decisions Are Interdependent. As previously noted, a change
         in one aspect of a project by one engineering team often requires
         changes in other aspects of the project by other teams. It is difficult
         in the conventional decision engineering process to ensure that all
         such interdependent changes are made and that the final engineering
         product is internally consistent. One miscalculation can adversely
         affect many aspects of the project.

- -        Participants Must Work Sequentially. Engineering a complex project is
         largely an iterative process. Engineering decision interdependence and
         the capture of key information in separate, specialized databases
         usually require engineering teams in the conventional decision
         engineering process to work in a strictly sequential, rather than in a
         concurrent, collaborative manner. A delay in the work of one team can
         thus delay the work of many other teams.

- -        Time and Cost Constraints Limit the Testing of Alternative Process
         Design Solutions. Even with the large internal engineering staffs that
         owner-operators and E&C companies have traditionally maintained, time
         and cost constraints force internal staff engineers to make simplifying
         assumptions that limit the accuracy of their analysis and require them
         to evaluate only parts of the process design, rather than the whole, or
         to consider fewer alternative process design solutions. This deficiency
         is exacerbated by corporate downsizing/re-engineering, which has
         resulted in substantial engineering staff cuts at major
         owner-operators.

- -        Owner-Operators and E&C Companies Find It Difficult To Communicate. The
         transfer of data and analyses from the owner-operator to the E&C
         company and back is


                                     - 37 -
<PAGE>   42
         complicated by the use of different methodologies and systems. The lack
         of a common language increases expense and reduces the quality of the
         decisions made.

         The foregoing deficiencies reduce the ability of a senior executive in
an owner-operator to: (i) focus the overall project evaluation process on
business priorities, (ii) increase the efficiency of the process so that more
proposed projects can be evaluated in the same amount of time without increased
resources, (iii) respond in a timely fashion to changing market conditions, and
(iv) more effectively manage the owner-operator's relationship with the E&C
company that will ultimately perform the final plant engineering and
construction. A senior executive in an E&C company faces similar limitations.

         Numerous efforts have been made to address the deficiencies of the
conventional decision engineering process through computerization. The earliest
software was mainframe based, performed only basic cost calculations and usually
supported the work of only specialized cost estimation teams. This software did
not (i) eliminate the need for engineers from other disciplines to develop
specialized databases or engage in calculation-intensive data manipulation, (ii)
provide all engineering teams with concurrent access to key information nor
(iii) more effectively address the interdependence of engineering decisions.
Despite efforts by owner-operators and E&C companies to mitigate these
continuing problems by custom designing engineering programs for specific
projects, mainframe-based computerization continued to produce imprecise results
that required thorough manual review and revision.

         The deployment of powerful Windows-based desktop computers linked by
networks have provided a large number of engineers and project execution
professionals with access to computerized engineering tools for the first time.
Despite the progress demonstrated by some desktop CAE software products that
incorporate a standardized base of information for use in process simulation and
design and cost modeling, new and old users of computerized engineering tools
still face many challenges in completing their engineering simulation, modeling
and analysis.

         First, users are still required in many instances to develop
specialized databases of design and cost information and to then laboriously
enter the data into spreadsheet-style programs, which perform only basic data
compilation and arithmetic functions. In most cases, users working on different
aspects of the same project still do not have concurrent access to key data and
expertise. Second, the results of one engineering team's work are not
concurrently integrated with the results of other teams, so users have to remain
constantly vigilant to ensure that engineering decisions in one aspect of a
project are reflected in all other aspects of the project. Third, users often
encounter software compatibility problems when using desktop CAE products from
different vendors, which often use different proprietary databases. Finally,
most CAE programs do little to enhance senior management's ability to control
and shape the decision engineering process.

         In short, despite the desktop revolution in computing, which made
computerized engineering tools available to larger numbers of users, the CAE
software most engineers use today still fails to incorporate data, and also
fails to automate and integrate the decision engineering process in an effective
and efficient manner.

THE ICARUS SOLUTION

         The Company's current line of AutoDE software products directly address
a number of the deficiencies of the conventional decision engineering process by
comprehensively automating and integrating important steps in the process, such
as process engineering and cost engineering. The Company's products reduce the
overall time and expense of the decision engineering process, while also
enabling participants--particularly senior executives--to take greater control
of the process so that business priorities drive engineering considerations,
rather than the reverse.

         Developed with the input of on-staff engineers from many disciplines
(including chemical, mechanical, structural, civil and electrical engineers) the
Company's AutoDE products provide all process participants concurrent access to
automated process design simulation tools, automated design and cost models and
comprehensive, frequently updated design, cost and engineering databases. ICARUS
products anticipate the needs of engineering and project execution professionals
and senior executives, allowing them to (i) quickly and easily examine
alternative process designs through the use of realistic simulations, (ii)
rapidly create detailed design and cost models and (iii) prepare preliminary
engineering and construction schedules. Using the Company's products, different
engineering teams can work concurrently on the same project without having to
spend substantial amounts of time on repetitious data entry and manipulation.
The teams can share their data and expertise with the assurance that a change
made in one area, such as process design, will be automatically reflected in
other engineering areas, such as mechanical, electrical or civil engineering. In
this way, the overall commitment of resources to the project can be reduced even
as the teams jointly improve the quality of their project evaluation effort by
performing extensive alternative scenario analysis.

         Customers have told ICARUS that the Company's products enable them to
reach a decision on whether or not to proceed with a project in approximately
one-fifth of the time previously required by conventional decision engineering
tools. Using the Company's products, owner-operators are also able to enhance
the quality of overall strategic decision-making, respond more quickly to market
changes and improve overall project design. E&C companies are able to reduce the
costs of preparing, and enhance the quality of, bids on projects, thus reducing
the risks they incur under turnkey, lump-sum project contracts. The Company
believes that a number of its customers have licensed ICARUS products because
they could not adequately address their decision engineering needs with
competing tools.

         The Company believes that it currently provides the only commercial
integrated process manufacturing CAE product line. The Company's products
utilize common proprietary elements, including automated models, expert system
modules and databases, and can be integrated with CAE and other software
engineering products developed by other vendors. By enabling users to use the
results generated by one product as the starting point for another product, this
integration eliminates many of the labor-intensive steps associated with
information transfer and manipulation in the conventional decision engineering
process and allows engineers from different disciplines to communicate and
collaborate more effectively. For example, using the Company's process
engineering product, ICARUS Process Evaluator, a customer can take the output
of a process


                                     - 39 -
<PAGE>   44
simulation program developed by another vendor, specify additional basic
premises and then rapidly simulate a manufacturing process plant design. The
customer can then electronically transfer a file to the Company's design and
cost engineering product, ICARUS 2000, which will quickly develop detailed
preliminary design and cost models of that process plant design under varying
conditions. These steps can be repeated many times to identify the optimal
process plant design.

         The data and analyses produced by the Company's products can also be
used to "jump start" the plant engineering process that follows decision
engineering. For example, such data and analyses can be used to help populate
downstream CAD/CAE applications that will generate the detailed drawings to be
used in actual construction. Additionally, certain ICARUS products directly
address steps in the plant engineering process, such as construction scheduling
and cost estimation for smaller construction projects at existing plants.

STRATEGY

         The Company's strategy is to expand its portfolio of integrated AutoDE
software products to meet customer needs in every stage of the process
manufacturing plant lifecycle--from the business development decision to
consider entering a process manufacturing segment, through the process and cost
engineering analysis of a specific proposed plant, to the detailed engineering,
construction scheduling and operations and maintenance activities that follow
the decision to proceed with a proposed plant. For the decision engineering
process, which encompasses business development, process engineering and cost
engineering, ICARUS currently offers process engineering and cost engineering
products. The Company plans to supplement these products and also to release a
new suite of business development products designed to enable senior executives
to analyze high-level, early-stage technological and economic feasibility
issues. This suite of products also will assist senior executives in ensuring
that their engineering staffs are focused on the business impact of their
engineering work. For the plant engineering process, which encompasses detailed
engineering/procurement, construction scheduling and operations and maintenance,
ICARUS currently offers construction scheduling and cost estimation products and
plans to release an object database product that will support plant engineering
applications such as CAD/CAE production of detailed construction drawings.

         The Company believes that developing and marketing a comprehensive
portfolio of products that provides users throughout a customer's organization
with common AutoDE software tools that operate with one another and with CAE
software products supplied by other companies will substantially enhance its
competitive position. A comprehensive portfolio of products will also provide
customers with a "migration path" to buy other Company products as their need to
automate additional engineering functions grows. See "- Products and Product
Development."

         The key elements of the Company's business strategy are as follows:

         Leverage the Company's Existing Customer Base to Introduce New
Integrated AutoDE Products. Because of its consistent delivery of quality
products, product updates, training and user conferences, the Company enjoys
strong relationships with many of its customers. The Company believes that these
relationships can be leveraged to market and sell new,


                                     - 40 -
<PAGE>   45
integrated products to such customers. The Company also believes that it can
leverage its reputation in the chemical and petroleum refining industries to
market and sell such products to new customers in those industries. The Company
intends to recruit additional senior sales and technical personnel to capitalize
on this opportunity. See "- Customers."

         Continue to Maintain Technology Leadership by Developing Innovative
AutoDE Software. The Company will continue to expend significant resources to
build on its core technology and develop new technology to create innovative,
integrated AutoDE products and maintain the Company's technology leadership
position within the market it serves. During calendar 1998, the Company plans to
nearly double the number of its product offerings. See "Products and Product
Development."

         Increase the Penetration of the Company's Products in the Pulp and
Paper, Pharmaceutical, Power and Food Industries. The Company has a solid
customer base in the chemical and petroleum refining industries. The Company
intends to increase its efforts to expand its customer base in the paper and
pulp, pharmaceutical, power and food industries. Because the decision
engineering analysis related to process manufacturing in different industries
involves many of the same concepts, the Company's AutoDE products may be
utilized in different industries with relatively few adjustments.

         Increase Its Consulting Efforts to Provide Integrated Turnkey
Engineering Solutions. A number of the Company's customers currently seek, on a
limited basis, the Company's assistance in integrating their proprietary
technology with the Company's software, reviewing work performed by the
customers' internal staffs or performing front-end design and cost studies. The
Company believes that many of its customers would respond favorably if the
Company offered comprehensive consulting and training services. The Company
intends to dedicate substantial resources to develop such integrated turnkey
engineering solutions.

         Enter into Strategic Alliances That Accelerate Product Development and
Enhance Marketing and Sales Opportunities. The Company has recently entered into
three strategic alliances with leading technology and research companies that
will provide access to valuable process design and cost data and accelerate the
development of new products, including products that address stages in the
process manufacturing plant lifecycle not currently covered by the Company's
products. The Company believes that these and possible future strategic
alliances may provide the best opportunity to introduce certain products and
open new marketing and sales opportunities. See "- Strategic Alliances."

         Pursue Acquisitions to Further Product Development, Sales and Marketing
and Consulting Services. The Company intends to pursue acquisitions that will
expand its product line, increase its customer base and enhance its ability to
offer comprehensive consulting services. ICARUS believes that it can effectively
compete for acquisition opportunities because of its leadership position in
process manufacturing CAE software and its knowledge of the market and potential
acquisition targets.

PROPRIETARY TECHNOLOGY AND DATABASES

         The Company's core proprietary technology includes, but is not limited
to, its automated design and cost models, the expert (or knowledge-based)
systems incorporated into its artificial intelligence modules, its
object-oriented project databases and other proprietary databases.

         Design and Cost Models. The Company has developed automated design and
cost models for most standard process manufacturing plant equipment types,
including the process and solids handling equipment used for heat transfer,
distillation, chemical reaction, pumping, compressing and other functions. These
models also cover the materials needed to install such equipment in a process
manufacturing plant, such as piping, steel, instrumentation, electrical,
insulation and paint. Drawing on fundamental laws of chemistry and physics and
proprietary databases, the Company's design and cost models automate and
integrate the following engineering elements: (i) "best practices" expertise
from expert engineers in many different engineering disciplines (including
process, mechanical, structural, civil and electrical engineering); (ii)
engineering design standards and codes for many countries; (iii) construction
methodology for determining the equipment, material, fabrication, labor, expense
and time requirements for a given project; (iv) volumetric calculations used to
determine the change in material requirements when a project is scaled up or
down; (v) costing the various inputs such as labor and materials needed to
complete a project; and (vi) critical-path-method construction scheduling.

         Expert Systems. An expert system is a computer program designed to
emulate a human expert in a particular limited field of knowledge. Expert
systems improve productivity by helping users make decisions when a human expert
is unavailable or too expensive. These expert systems automatically calculate
the design and cost impact of changes made by multiple engineering teams working
on the same project and help to solve problems associated with the
interdependence of engineering decisions. ICARUS Mentor is an expert system
software development tool that the Company has used to develop expert system
modules that are included in the Company's current line of products to enhance
the performance of the automated design and cost models. These modules can be
customized by users to incorporate customer-developed expertise.

         Object-Oriented Project Database. The Company has developed an
object-oriented project database designed to serve as the central repository of
information pertaining to a particular project throughout the decision
engineering and plant engineering processes. Information contained in such a
database may include, but is not limited to, process solution results, plant
components, design data, capital costs and schedules, operating costs and
investment analysis results and graphical data relating to process flow
diagrams, piping and instrumentation diagrams and plot plan drawings.

         Proprietary Databases. Finally, the Company has developed extensive
proprietary databases that include engineering design and cost information from
a variety of public and private sources, including information from customers.
These databases are embedded in the Company's products and are updated regularly
to provide customers with current cost and other data. The databases can be
customized by users to incorporate customer-developed information.

STRATEGIC ALLIANCES

         In 1994, ICARUS entered into a strategic alliance with Primavera
Systems Inc. ("Primavera"), a leading provider of scheduling software. Pursuant
to a multiple-year renewable marketing and product development agreement, the
two companies have combined the Company's design and cost modeling and
engineering automation expertise with Primavera's scheduling expertise. The
resulting integrated design estimating and scheduling product, ICARUS Project
Manager, has been marketed by the Company to hundreds of authorized users in 22
countries since fiscal 1995.

         ICARUS entered into three new strategic alliances for product
development and marketing in 1997. The Company expects that these strategic
alliances will enable it to integrate complementary technology and data into its
core products in a time- and cost- efficient manner; to create new products that
will be attractive to the customer base of both the Company and the other
participant in the alliance; to immediately add complementary products to its
product line; and generally to expand its revenue opportunities without a
significant up-front investment. The Company's current strategic alliances are
with SRI Consulting, Inc. ("SRIC"), Hyprotech, Ltd. ("Hyprotech") and Richardson
Engineering Services, Inc. ("Richardson"). See "- Strategy."

         Alliance With SRIC. In August 1997, the Company signed a multiple-year
renewable marketing and product development agreement with SRIC, a subsidiary
of SRI International, headquartered in Menlo Park, California, to
develop and market at least two new products based on the Company's current
process design and design and cost modeling products and its general decision
engineering expertise and SRIC's Process Economics Program ("PEP"), which
provides in-depth reports of process technology and economics for more than 800
chemical and refinery processes. The new products will be jointly marketed by
ICARUS and SRIC. See "- Products and Product Development."

         Alliance With Hyprotech. In July 1997, the Company, through a wholly
owned subsidiary, executed a multiple-year marketing and development agreement
with Hyprotech, a company headquartered in Calgary, Canada that supplies process
simulation solutions to an international customer base in the chemical and
petroleum refining industries. The companies agreed to jointly develop at least
two new products based on certain of the Company's existing products and
expertise and Hyprotech's technology. These products will be jointly marketed
and licensed by ICARUS and Hyprotech. See "Products and Product Development."

         Alliance With Richardson. In May 1997, the Company entered into a
multiple-year renewable technology licensing and marketing agreement with
Phoenix-based Richardson, which is a leading publisher of global process
manufacturing plant construction estimating standards. Under the agreement,
ICARUS has the right to use Richardson's unit cost construction database to
extend the capabilities of the Company's AutoDE software products in plant
engineering. Under the agreement, the Company will market this technology and is
also authorized to resell Richardson's winRace software and database products to
the chemical industry.

         The Company may use a portion of the net proceeds of the Offering to
develop the products contemplated by these or future strategic alliances. See
"Use of Proceeds."

PRODUCTS AND PRODUCT DEVELOPMENT

         The Company's current AutoDE software products are designed to run on
standard PC hardware and operating platforms, including Windows 95, Windows NT
and UNIX. They incorporate an easy-to-use graphical user interface, automated
design and cost models, artificial intelligence modules, and embedded databases.
The Company works continually to enhance its products to operate on new
operating systems, updates of existing operating systems and new network
topologies, including the client-server environment.

         A common feature of the Company's existing products is a proprietary
electronic hardware device called the "Control Device." The Control Device is
independent of the customer's computer hardware platform and is designed to
prevent unauthorized and unlicensed use of the Company's products. The Company's
products are designed so that they cannot be operated without the Control
Device, which resembles an external modem and plugs into the desktop computer's
serial port. Every time a Company product is used, the Control Device verifies
the licensed user's identifier to permit entry. When the license period ends,
the Control Device is designed to prevent further entry into the product. The
Control Device has been used by the Company on a wide variety of hardware and
operating system platforms since 1992.

         The Company's business strategy is to expand through internal
development, acquisitions, and strategic alliances its portfolio of integrated
AutoDE software products to meet customer needs at every stage of the process
manufacturing lifecycle--from the business development decision to enter a
process manufacturing niche, through the process and cost engineering of a
specific proposed project, to the detailed engineering and procurement,
construction scheduling and operations and maintenance activities that follow
the decision to proceed with the proposed project. These products are designed
to respond to the different skills and decision criteria applied by engineers
from different disciplines and by decision-makers that do not have substantial
engineering knowledge. Consistent with this strategy, ICARUS entered into three
strategic alliances in calendar 1997. See "- Strategic Alliances."

         During fiscal years 1998 and 1999, ICARUS plans to release the
following products, most of which will focus on the business development and
process engineering stages of the plant lifecycle:

         ICARUS Decision Engineering Analyzer. Designed for use by senior
executives as well as by engineers, ICARUS Decision Engineering Analyzer
("Analyzer") will enable a user to enter basic information on the scope and
features, such as product and product capacity, of a proposed major project.
This basic information can be derived from ICARUS/SRIC products discussed below
or from proprietary data developed by a customer. Using this basic project scope
definition, Analyzer will automatically develop a detailed early conceptual
design. Analyzer will also produce estimates of design quantities, engineering
tasks and associated effort, procurement and construction work products and
tasks, field manpower, costs of project components, engineering and construction
schedules, investment and operating costs, and economic and financial reports.
The product's reporting modules will produce graphic and text reports, such as
block diagrams, linked process flow diagrams and piping and instrumentation
diagrams, data sheets, and line lists. Additionally, Analyzer will produce input
files for key CAE applications used by the customer's internal engineering staff
so that a senior executive or staff user can perform value-added engineering on
an interactive, dynamic basis.

         ICARUS-SRIC Process Model and Project Model. ICARUS and SRIC plan to
develop a Process Model and a Project Model for each of SRIC's more than 800
chemical and refinery processes. Process Model will be an interactive
multimedia software containing SRIC's PEP technical content and the results of
the Company's project evaluation technology applied to a specific process, such
as the production of gasoline. This multimedia document will be used to
evaluate major issues relating to a customer's potential entry into a
particular product line. By extracting process intelligence input data from a
specific PEP report, Project Model will automatically create for a user of
ICARUS 2000 or ICARUS Process Evaluator detailed conceptual designs and
estimates for a proposed process manufacturing plant. Using this information,
the user can easily produce cost analyses and other specialized project
information.

         ICARUS plans to sell Process Model and Product Model separately or as
part of an integrated software bundle called the Decision Engineering Tool Suite
that will include the ICARUS Decision Engineering Analyzer. The Company expects
that this product suite will be used for a variety of business development
purposes, including front-end analysis by


                                     - 46 -
<PAGE>   51
senior executives of whether an owner-operator should enter a specific process
manufacturing niche.

         Hyprotech-ICARUS Products. ICARUS and Hyprotech are developing two
products that combine Hyprotech's process evaluation expertise in chemical
process design with the Company's design and cost engineering expertise.
Plant-Product is intended to be marketed primarily to process engineers that
use Hyprotech's products but have little or no prior cost engineering
experience or responsibility. They will enter static design data to generate
detailed cost estimates. Process-Product will be marketed primarily to process
engineers that use Hyprotech's products to help them produce cost estimates and
schedules of engineering and construction.

         ICARUS Project Object Database ("IPOD"). ICARUS is developing an
object-oriented database product that will serve as the central repository of
information (such as process simulation results, plant components, design data,
capital costs and schedules, operating costs and investment analysis results and
graphical data pertaining to a specific process manufacturing project throughout
the decision engineering and plant engineering processes. A customer can use
IPOD, which will be implemented on a client-server platform, to automatically
populate numerous other CAD/CAE software applications (from a variety of
vendors) relating to the engineering, construction, operations and maintenance
and financial reporting of a specific plant.

         ICARUS-Richardson Construction Estimating Modules. ICARUS is in the
early stages of developing a product that integrates the Company's design and
cost modeling technology with Richardson's unit cost estimating technology to
provide customers with enhanced cost estimating capability during the detailed
engineering/procurement and construction stages of a project.

         As of October 31, 1997, 19 of the Company's employees were directly
involved in internal product development. The Company's product development
expenditures for the six months ended October 31, 1997 and for the year ended
April 30, 1997 were $511,000 and $904,000, representing 12.0% and 12.3% of total
revenue, respectively. The Company has made substantial investments in, and
intends to use a portion of the net proceeds from this Offering for, product
development. See "Use of Proceeds," and also see "Management's Discussion and
Analysis of Financial Condition and Result of Operations - Overview" for
information relating to the expensing of the Company's research and development
costs.

         ICARUS believes that its future performance will depend in large part
on its ability to maintain and enhance its current product line, develop new
products that achieve market acceptance, maintain technological competitiveness
and meet new customer requirements. The Company's product development efforts
are subject to numerous risks and no assurance can be given that the Company's
product development goals will be realized. See "Risk Factors - Risks Associated
with Continued Product Development; Rapid Technological Change" and "- Market
Acceptance of the Company's Products."

COMPANY SERVICES

         The Company believes that the services it offers help to maintain
customer loyalty and increase potential license renewals and the number of
licensed users in a particular


                                     - 47 -
<PAGE>   52
customer's organization. The Company believes that strong customer support is
crucial, both to the initial marketing of its AutoDE software products and to
ensure that its customers successfully apply its AutoDE software products to
their engineering automation needs so that they will be encouraged to renew and
expand their license arrangements with the Company. In addition, the Company
believes that every customer support contact creates a marketing opportunity to
license its AutoDE software products to additional users at a customer's
location and to license additional AutoDE software product to users at other
customer locations.

         Training. The Company offers introductory and advanced training courses
at its Rockville, Maryland; Houston, Texas; Altrincham, England; and Tokyo,
Japan offices and, from time to time, at the offices of its customers to train
licensed users of its AutoDE software products. These seminars generally run
between one and four full days, depending upon the product and/or platform being
taught. The Company typically charges licensed users for such training. Product
training is not mandatory, but the Company believes that such training enhances
the value of the licenses purchased by the customer and is highly recommended.
The Company believes that continuing product training helps build product
loyalty and reinforces the value of the Company's product to the customer.

         Post-Contract Support. The Company also offers free technical support
to its licensed users by telephone from a help-desk located in its Rockville,
Maryland offices. The help-desk is available during business hours Monday
through Friday. In addition, the Company typically provides to its licensed
users and to customers having annual maintenance plans a "cost update" for
materials, equipment and labor, the data for which is obtained from publicly
available cost information received from the Company's customers, vendors,
published data sources and from the Company's proprietary pricing models. This
update typically is released in early summer. From time to time and on an "as
available" basis, the Company may issue an update that contains one or more new
features for the AutoDE software product, such as new report types, new screens
for data input, new equipment models and the resolution of software problems or
"bugs."

         Consulting Services. A number of the Company's customers currently
seek, on a limited basis, the Company's assistance in integrating their
proprietary technology with the Company's software, reviewing work performed by
the customers' internal staff or performing front-end design and cost studies.
The Company believes that these services leverage software sales because the
customer must have a license to its AutoDE software products in most instances
in order to use the cost model, application or customization delivered by the
consulting team. Application projects enable the Company to provide turnkey
solutions to customers who do not have the resources to build their own design
and cost models. These projects provide an important mechanism for the Company
to extend the range of applications that its technology can model. Although the
Company enters into agreements to protect the customer's proprietary information
in these consulting projects, the Company typically retains the right to use the
generic design and cost modeling methods, expert systems and know-how developed
as a result of the project in other Company AutoDE software products. The
Company expects to increase the scope and depth of its consulting services in
the future. See "Business - Strategy."


                                     - 48 -

         The provision of services by the Company to its customers for the six
months ended October 31, 1997 and the year ended April 30, 1997 represented
approximately 6.2% and 7.1% of total revenues, respectively.

CUSTOMERS

         The Company currently has over 300 customers worldwide who represent
all segments of the process manufacturing industry and the engineering and
construction firms that serve them. One or more of the Company's products are
licensed to 18 of the top 20 chemical companies and 18 of the top 20 petroleum
refining companies, as such companies are listed in the "1997 Fortune 500 List,"
and 8 of the top 10 chemical plant contractors listed in Engineering News
Record's "Top 400 Contractors."

         The following is a representative list of the Company's larger
customers.

         The Company derives a significant portion of its total revenue from
software licenses to companies in the chemical and petroleum refining
industries, which are highly cyclical. See "Risk Factors - Concentration of
Revenue in the Chemical and Petroleum Refining Industries." As a consequence,
the Company is focusing greater resources on developing products and marketing
efforts directed at companies in process manufacturing segments of other
industries. No individual customer accounted for 10.0% or more of the Company's
total revenues for the six months ended October 31, 1997 or fiscal 1997.
Although all of the customers listed above are current licensees of the
Company's AutoDE software, there can be no assurance that any of them will
continue to license any of such products beyond the term of the existing
license.

         The Company believes that its ability to maintain and grow its customer
and revenue bases will depend, in part, on its ability to maintain a high level
of customer satisfaction. The Company believes that its customers typically
purchase AutoDE software products only when they are convinced that such
products will provide them with quicker and more reliable results than the
software they are currently utilizing (which is typically developed "in-house"
by the customer). The Company believes that its customers are its best sales
representatives and finds that sales within an organization are easier once
there is a licensed user in that organization.

SALES AND MARKETING

         The Company markets its products and services in more than 25 countries
around the world through its direct sales force, which as of October 31, 1997,
consisted of 12 full time Company sales personnel based at the Company's
Rockville, Maryland office, its United Kingdom offices located in Altrincham,
England and its Asian offices located in Tokyo, Japan, and through its
independent sales representatives located in Argentina, Australia, Brazil,
Colombia, France, Germany, India, Saudi Arabia, South Africa, South Korea,


                                     - 50 -
<PAGE>   55
Venezuela and certain independent republics of the former Soviet Union, and an
independent sales representative that markets the Company's products in the
People's Republic of China. The Company relies on its direct sales force to
initiate sales contacts, follow-up on leads provided by the Company's marketing
department and to engage in face-to-face contact with its customers to solicit
orders. The Company believes its Company sales personnel have a number of strong
relationships with existing customers which assists the sales personnel in
obtaining additional users of Company products currently licensed by its
customers and in obtaining licenses of additional AutoDE software products. As
of October 31, 1997, the Company had agreements with 13 independent,
non-exclusive sales representatives in 14 countries worldwide. These agreements
are for a term of one year, automatically renewable for an additional one year
term unless sooner terminated. Such international sales typically are priced in
United States dollars, English pounds or Japanese yen; product is generally
shipped with thirty day payment terms. Sales by the Company's independent sales
representatives were $317,000 for the six months ended October 31, 1997 and
$499,000 for fiscal 1997.

         The Company also has an in-house marketing department that designs and
updates the Company's home page on the World Wide Web and its sales materials
and performs demographic studies of new sales territories to identify potential
customers. The marketing department also works with the sales force on direct
mail, e-mail and facsimile and other marketing campaigns to gauge and generate
the interest of potential customers.

         The Company sells primarily through direct contact with customers and
does not conduct significant mass market advertising due to the expense involved
and the inability to target the Company's particular customer base through such
advertising. It does, however, publish articles and advertise selectively in
professional trade publications, such as Chemical Engineering and Chemputers
magazines. The Company also publishes the SUN (its System User Newsletter) three
times per year to keep industry participants informed about news of interest
regarding ICARUS technology. The SUN is in its ninth year of publication. The
ICARUS Internet site on the World Wide Web is also used to keep its current and
potential customers informed about the latest information and developments in
process and project evaluation. In conjunction with licensed users of its
technology, the Company sponsors User Group meetings in various locations having
a concentration of Company customers to increase the proficiency of its user
community in the effective use of its products. In recent years, the Company has
also sponsored the ICARUS International User's Conference, at which customers
had the opportunity to review major industry trends, learn about the Company's
development plans and meet with industry experts. The Company believes that the
ICARUS International User Conference provides a valuable service to its
customers and assists in enhancing the Company's reputation as a leading
provider of AutoDE software to the process manufacturing industry. Moreover, the
Company actively participates in trade shows such as the Chemputers Show in the
United States and Europe each year, the Chem Show, TAPPI (Technical Association
of Pulp and Paper Industry), the Petro Expo and Daratech, as well as
international trade fairs.

COMPETITION

         The growing market for CAE software used in process manufacturing is
intensely competitive and the Company's competitors include several companies
that possess significantly greater financial, technical, marketing and other
resources than ICARUS. The


                                     - 51 -
<PAGE>   56
Company's primary competition currently comes from customers and potential
customers that have developed, or have the resources and capabilities to
develop, their own process engineering, cost engineering and construction
scheduling software solutions. The Company's direct third-party competitors
include Timberline Software Corporation and a number of smaller private
companies. To a lesser degree, ICARUS faces competition or potential competition
from Aspen Technology, Simulation Sciences Inc. and ChemStations, Inc. The
Company expects to face additional competition as other established and new
companies enter the computer-aided engineering simulation and analysis software
market and new products and technologies are introduced. Increased competition
could result in price reductions, fewer customer orders, reduced gross margins
and loss of market share, any of which could materially adversely affect the
Company's business, operating results and financial condition.

         In order to compete in the marketplace, ICARUS must persuade a customer
or potential customer that the Company's AutoDE software products offer a
superior solution to internally developed software or CAE products supplied by
other vendors. In doing so, ICARUS emphasizes the quality and sophistication of
its products, the technological expertise and creativity of its personnel, the
frequency with which it releases AutoDE software enhancements and updates the
quality of its technical support and training courses. Increasingly,
owner-operators and E&C companies that have for years developed and maintained
their own CAE simulation and analysis software are recognizing the efficiency
and economic gains they can achieve by deploying commercially developed CAE
software, including the Company's AutoDE software products.

PROPRIETARY RIGHTS

         The Company relies primarily upon trade secret and copyright laws,
including the use of invention assignment and confidentiality agreements with
employees and confidentiality agreements with third parties, and physical
security devices such as its Control Device to protect its proprietary
technology. The Company presently relies upon its registered trademarks and
service marks as well as common law rights in its trademarks and service marks
to protect the use of its name and brands. The Company maintains United States
registrations of certain trademarks and service marks and has filed applications
for United States registrations on additional trademarks and service marks. The
Company's ability to protect its products in foreign jurisdictions, however, is
limited in that the laws of certain foreign jurisdictions in which the Company's
products are distributed do not protect the Company's intellectual property
rights to the same extent as the laws of the United States. Therefore, there can
be no assurance that the protection provided by the laws of either the United
States or of foreign jurisdictions will be sufficient to protect the Company's
proprietary rights in its products and technology.

         The Company presently enters into invention assignment and
confidentiality agreements with its employees and confidentiality agreements
with certain customers. The Company also limits access to the source code to its
AutoDE software and other proprietary information. The Control Device is
designed to prevent unauthorized users from utilizing the Company's AutoDE
software products and shuts down the product after the license period expires.
The Company's AutoDE software also will not operate on a computer which is not
connected to the Control Device. It is difficult, however, to totally prevent
unauthorized use. There can be no assurance that the steps taken by the Company
in this


                                     - 52 -
<PAGE>   57
regard will be adequate to prevent misappropriation of its technology or
infringement of its copyrights or that the Company's competitors will not
independently develop technologies that are substantially equivalent or superior
to the Company's technology. The Company believes, however, that due to the
rapid pace of innovation within the software industry, factors such as the
technological and creative expertise of its personnel, the quality of its
products, the quality of its technical support and training services, and the
frequency of release of software product enhancements are more important to
establishing and maintaining a technology leadership position than the various
legal protections available for the Company's products and technology.

         Certain technology used in the Company's AutoDE software products, such
as the Primavera Project Planner, Empress SQL and Hummingbird XCEED, are
currently licensed from third parties. These licenses generally require the
Company to pay royalties and/or license fees and to maintain the confidentiality
of certain matters. The Company believes that there are alternative sources for
each of the material components of the technology licensed by the Company from
third parties. However, the termination of any of such licenses, or the failure
of the third party licensors to adequately maintain or update their products,
could result in delay in the Company's ability to ship certain of its products

EMPLOYEES

         As of October 31, 1997, the Company had a total of 58 full-time and 4
part-time employees, including 33 in sales, marketing and technical support and
training, 19 in product development and 10 in finance and administration. Of
these employees, 6 work in the Company's United Kingdom office and 2 work in the
Company's Tokyo, Japan office. None of these employees is engaged pursuant to a
collective bargaining agreement, nor has the Company experienced any labor
actions such as a work stoppage. The Company believes that its relations with
its employees are good.

LEGAL PROCEEDINGS

         Prior Legal Proceedings. In 1985, the Company settled a dispute with
the IRS regarding the Company's income taxes for the fiscal years 1977 through
1982. It was the Company's understanding that the IRS would accept a payment
plan, including interest, for the disputed amount. After the settlement papers
were signed, and the IRS obtained financial information from the Company
relating to developing such a payment plan, it appeared that the IRS believed
that the Company had sufficient cash reserves to permit an immediate payment.
The Company contended that these funds represented working capital which was
needed for corporate expansion and other operations. Negotiations to arrive at a
mutually satisfactory payment plan with the IRS could not be satisfactorily
concluded. Consequently, the Company thereafter filed a petition under Chapter
11 of the U.S. Bankruptcy Code in 1985 to allow the Company and the IRS to work
out a payment plan satisfactory to both parties. The Company emerged from
Chapter 11 when its Plan of Reorganization was confirmed by the Court in 1988.
All payments required under the Plan of Reorganization were made, the final
payment being made in December 1993 and the case


                                     - 53 -
<PAGE>   58
was subsequently closed. The Company believes that these proceedings have had no
adverse effect on the Company's current business, financial condition or
reputation.

         In 1979, a federal grand jury for the Eastern District of Virginia
returned a criminal indictment against the Company, Herbert G. Blecker, Chairman
of the Board, President and Chief Executive Officer of the Company, and an
employee of Computer Sciences Corporation ("CSC"), a company the shares of which
were and are traded on the New York Stock Exchange. The indictment arose out of
events relating to a contract between the GSA and CSC and a subcontract between
CSC and the Company. In 1972, CSC was awarded a multi-million dollar contract by
the GSA to provide federal agencies with computer and data processing services
(the "GSA/CSC contract"). That contract authorized CSC to subcontract for
consulting services. In 1972, CSC subcontracted with the Company for those
services. Under the GSA/CSC contract, the rates charged for consultant services
were to be based upon the education and experience of the consultants who
performed services. The prosecution contended that Mr. Blecker instructed a
number of employees of the Company to embellish their resumes with additional
degrees and experience which they did not have and, further, that he caused the
resumes of other employees to be enhanced without their knowledge. The 37 count
indictment alleged that the Company and Mr. Blecker submitted to the CSC
invoices for fees based on the false resumes. Further, the indictment asserted
that the Company and Mr. Blecker knew that CSC, in turn, would present to the
GSA claims for payment based upon the invoices. The case was tried before a
jury. The Company and Mr. Blecker were convicted on six counts of presenting
false claims to an agency of the United States and, in addition, the Company was
convicted on two counts of mail fraud. The Company was fined $62,000 and Mr.
Blecker received a one-year sentence of confinement, of which he served nine
months.

         Following this conviction, the GSA issued a debarment order which
prevented the Company from entering into a contract or subcontract for the
performance of work for the government. The debarment was terminated as of April
22, 1983, thereby eliminating any restrictions on the ability of the Company to
perform services for the government.

         In October 1980, a grand jury in the Eastern District of Virginia
returned a criminal indictment against Mr. Blecker, CSC, and five current or
former officers and employees of CSC. The charges in this indictment also arose
out of the GSA/CSC contract referred to above. The charges involved alleged
improper billing for computer services and for computer software packages. Mr.
Blecker was charged with one count of conspiracy, one count of violating the
Racketeer Influenced Corrupt Organizations Act (RICO), six counts of mail fraud,
and two counts involving alleged false claims against the government. This case
was tried by a jury in May 1983, and all of the defendants were acquitted.

         The Company believes that the matters described above have had no
adverse effect on the Company's recent business, financial condition or results
of operations.

         Current Legal Proceedings. On October 7, 1997, a former employee of
the Company's U.K. subsidiary, ICARUS Services Limited ("ISL"), filed suit
against ISL in the High Court of Justice, Manchester District, United Kingdom.
The suit seeks approximately 75,000 pound sterling (approximately U.S.
$125,000) for compensation relating to the former employee's termination of
employment in early 1997, pursuant to an employment contract between ISL and
the former employee. ISL has filed a defense with the High Court denying
                         

                                     - 54 -
<PAGE>   59
indebtedness to the former employee; however, as of the date of this Prospectus,
a hearing date has not been set. The Company intends to vigorously defend itself
against this action. It has established a reserve of approximately $110,000 as a
result of the foregoing claim and believes that any liability exceeding such
amount would not have a material adverse effect on the Company's business,
financial condition or results of operations.

         The Company is also a party from time to time to certain legal
proceedings arising in the ordinary course of its business, none of which is
expected to have a material adverse effect on the Company's business, financial
condition or results of operations.

FACILITIES

         The Company's principal administrative, sales, marketing and product
development facility occupies approximately 17,500 square feet in Rockville,
Maryland pursuant to a lease which requires annual rent of $382,800 and expires
on March 31, 1998. The Company anticipates relocating to larger quarters located
at 600 Jefferson Plaza, Rockville, Maryland, by April 1, 1998, pursuant to a new
ten (10) year lease dated December 31, 1997, for approximately 28,900 square
feet at an annual base rent of $571,210 plus increases in operating expenses.
The Company also leases 4,535 square feet of office space in Houston, Texas
which lease requires an annual rent of $91,585, plus all operating expenses of
the leased premises as such costs may increase from time to time and expires on
April 1, 2002, and leases approximately 1,921 square feet in Altrincham, England
which lease requires annual rent of 20,275 pound sterling (approximately US
$34,000) and expires on May 8, 2002, and leases approximately 1,070 square feet
of office space in Tokyo, Japan, which lease requires an annual rent of 3.6
million Japanese Yen plus 720,000 Japanese Yen (approximately US $36,000) for
utilities and expires on January 19, 2000. The Company believes that its
existing facilities are adequate for its current needs and that suitable
additional or alternative space will be available in the future on commercially
reasonable terms as needed.

(1) The Company anticipates granting Mr. Blecker 63,600 options to purchase
Common Stock pursuant to the Company's Stock Option Plan. See "- Stock Plans -
1998 Stock Option Plan."

(2) The Company anticipates granting Mr. Geritz 106,000 options to purchase

(3) Other Annual Compensation includes accrued but unpaid vacation and sick pay,
the lease and maintenance payments for an automobile, payment of personal
telephone charges and the payment for a home security system. Such amounts did
not exceed the lesser of $50,000 or 10% of the total amount of salary and bonus
reported for Mr. Blecker for the year ended April 30, 1997.

EMPLOYMENT AGREEMENTS

    Effective January 22, 1998, the Company entered into an employment
agreement with Mr. Blecker which superseded his employment agreement dated
August 1, 1981, and negotiated a new employment agreement with Mr. Geritz
(Messrs. Blecker and Geritz being referred to collectively as the "Executives").
Except for base salary amounts, terms of the employment agreements are
substantially similar. Each of the Executives are engaged for five year terms;
which terms will be automatically extended for an additional year upon each
anniversary date of the respective employment agreement. The aggregate base
salaries for the Executives in each of the calendar years 1998, 1999, 2000 and
2001 will be $250,000 and $125,000 for Mr. Blecker and Mr. Geritz, respectively.
The base salaries will be supplemented by a cash bonus as may be determined by
the Board of Directors with respect to Mr. Blecker and a cash bonus of $125,000
with respect to Mr. Geritz for his performance in fiscal 1998, payable in May
1998, as well as a cash bonus for fiscal years 1999, 2000 and 2001 to be based
on performance goals to be agreed upon by him and the Board of Directors, to be
payable quarterly in fiscal years 1999, 2000 and 2001.


                                      -61-
<PAGE>   66
The base salary amounts shall automatically be increased by the amount of the
prior year's increase in the consumer price index ("CPI"). The Executives are
entitled to participate in all employee benefit plans of the Company and will
be reimbursed for expenses relating to Company business. An automobile, the
lease payments and operating expenses of which will be paid by the Company,
will be provided to Mr. Blecker. Each Executive is entitled to four weeks paid
vacation, all Company holidays and sick leave in accordance with Company
policy. The employment agreements are terminable by the Company with or without
"cause" and upon the Executive's death, disability or retirement, or by the
Executives for "Good Reason." If the Company terminates the employment
agreement for cause or if the Executive terminates his employment for other
than Good Reason, the Executive will have no right to further compensation or
benefits under the employment agreement. If the Executive's employment is
terminated by the Company for other than cause, or for disability, retirement
or death or if the employment agreement is terminated by the Executive because
the Company has breached the employment agreement, the Executive will be
entitled to receive severance pay equal to three times the Executive's average
annual compensation. The Executive would also be entitled to maintain, at no
cost to him, the Company benefits he was then receiving (other than
participation in stock option or restricted stock plans) until he obtains
full-time employment with another employer or the expiration of the remaining
term of the employment agreement, whichever is earlier.
     
      With respect to the employment agreements, "Good Reason" is defined to
mean termination of employment following a change in control of the Company
(defined by his employment agreement to be an event that would be required to be
reported under Regulation 14A of the Securities Exchange Act of 1934, as amended
(the "Exchange Act") or the acquisition by any person of 25% or more of the
voting power of the Company or a change in the individuals constituting the
Board of Directors during any two consecutive years) based on: (i) failure to
elect, re-elect, or appoint or to re-appoint the Executives to their respective
offices or a material adverse change in their respective functions, duties or
responsibilities; (ii) a material reduction in their base salary; (iii) the
relocation of the Company's executive offices; (iv) any purported termination of
their respective employment without proper notice; or (v) the failure by any
successor to the Company to assume their respective employment agreements. If
the employment agreement is terminated for "Good Reason" subsequent to a Change
in Control, the Executive will be entitled to receive a lump sum cash severance
amount equal to five times his current base salary. The Executive would also be
entitled to maintain, at no cost to him, the Company benefits he was then
receiving (other than participation in stock options or restricted stock plans)
until he obtains full time employment with another employer or the expiration of
the remaining term of the employment agreement, whichever is earlier. The
Company has agreed to pay any excise tax attributable to any severance payment,
if necessary, pursuant to Section 4999 of the Internal Revenue Code of 1986, as
amended (the "Code"). 



                                      -62-
<PAGE>   67
      The Executives have agreed not to disclose any proprietary information of
the Company and not to compete with the Company for two years after the
termination or expiration of their respective employment agreement.

      Mr. Kingsley was hired in October 1996 at a base salary of $85,000 per
annum with a bonus of $10,000 based upon the performance and continued
profitability of the Company, which was paid on April 30, 1997. His current base
salary is $92,000.

STOCK PLANS

      1998 Stock Option Plan. Effective January 22, 1998, the Board of Directors
of the Company adopted the Stock Option Plan, which was approved by the
stockholders of the Company by unanimous written consent on January 22, 1998.

      The Stock Option Plan is designed to attract and retain qualified
personnel in key positions, provide officers and key employees with a
proprietary interest in the Company as an incentive to contribute to the success
of the Company and reward key employees for outstanding performance and the
attainment of targeted goals. The Stock Option Plan is also designed to attract
and retain qualified directors, consultants, agents and advisors to the Company.
The Stock Option Plan provides for the grant of incentive stock options intended
to comply with the requirements of Section 422 of the Code ("incentive stock
options") and non-incentive or compensatory stock options which may be granted
to non-employee directors or other persons who may not be employed by, or be
directors of, the Company (collectively "Awards"). Awards will be available for
grant to directors and key employees of the Company and its subsidiaries, except
that non-employee directors will not be eligible to receive incentive stock
options.

      The Stock Option Plan is administered and interpreted by the Compensation
Committee of the Board of Directors consisting of two or more non-employee
directors. Unless sooner terminated, the Stock Option Plan will be in effect for
a period of ten years or until January 21, 2008.

      Under the Stock Option Plan, the Compensation Committee will determine
which officers and key employees will be granted options, whether such options
will be incentive or compensatory options, the number of shares subject to each
option, whether such options may be exercised by delivering other shares of
Common Stock and when such options become exercisable. The Stock Option Plan,
however, provides that non-employee directors automatically will be granted
compensatory stock options to purchase a specified number of shares of Common
Stock annually.

      Pursuant to the Stock Option Plan, the per share exercise price of an
incentive stock option is required to be at least equal to the fair market value
of a share of Common Stock on the date the option is granted. The Code also
requires that the aggregate fair market value of the Common Stock with respect
to which the incentive stock options are exercisable for the first time by the
optionee during any calendar year cannot exceed $100,000. Moreover, any person
who owns 10% or more of the voting power of the Common Stock 


                                      -63-
<PAGE>   68
may not receive incentive stock options whose exercise price is less than 110%
of the fair market value of a share of Common Stock of the Company on the date
of grant. The Stock Option Plan requires that the per share exercise price of a
compensatory stock option be no less than 85% of the fair market value of a
share of Common Stock on the date the option is granted.

      Stock options will become vested and exercisable at the rate of 20% per
year on each annual anniversary of the date on which the option was granted or
as otherwise specified by the Compensation Committee, and the right to exercise
stock options shall be cumulative. Each stock option or portion thereof will be
exercisable at any time on or after its vesting date and will remain exercisable
until ten years after its date of grant or three months after the date on which
the optionee's employment terminates, unless the Compensation Committee, in its
discretion, decides at the time of grant or thereafter to extend such period of
exercise for a period of three months to five years. Unless the Compensation
Committee, in its discretion, shall specifically state otherwise at the time of
grant, all options will become immediately vested and exercisable in full on the
date an optionee terminates his or her employment or service as a non-employee
director due to his or her death, retirement, disability or as a result of a
"Change in Control" of the Company. A "Change in Control" of the Company is
defined by the Stock Option Plan to have occurred if: (i) any person other than
Mr. Blecker or the Company becomes the beneficial owner of 25% of more of the
voting power of the Company then outstanding; (ii) during any period of two
consecutive years individuals who at the beginning of such period constitute the
Board of Directors cease for any reason to constitute at least a majority of the
Board; (iii) the stockholders of the Company approve a merger or consolidation
of the Company whereby the voting securities of the Company represent less than
50% of the combined voting power of the Company immediately after such merger or
consolidation; or (iv) the stockholders of the Company approve a plan of
liquidation of the Company or an agreement for the sale or disposition of
substantially all of the Company's assets. However, failure to exercise
incentive stock options within three months after the date on which the
optionee's employment terminates may result in adverse tax consequences to the
optionee. Stock options are non-transferable except by will or the laws of
descent and distribution.

      The Company has reserved for issuance pursuant to the Stock Option Plan
760,500 shares of Common Stock. In the event of a stock split, reverse stock
split or stock dividend, the number of shares of Common Stock under the Stock
Option Plan, the number of shares to which any Award relates and the exercise
price per share under any option shall be adjusted to reflect such increase or
decrease in the total number of shares of the Common Stock outstanding.

      Under current provisions of the Code, the federal income tax treatment of
incentive stock options and compensatory stock options is different. With
respect to incentive stock options, an optionee who meets certain holding period
requirements will not recognize income at the time the option is granted or at
the time the option is exercised, and a federal income tax deduction generally
will not be available to the Company at any time as a result of such grant or
exercise. With respect to compensatory stock options, the difference between the
market value of the Common Stock on the date of exercise and the option exercise
price generally will be treated as compensation income to the optionee upon
exercise, and the Company will be entitled to a deduction in the amount of
income so recognized.


                                      -64-

<PAGE>   69
      No options were granted or exercised in fiscal 1997. The Company
anticipates granting immediately prior to the commencement of this Offering the
following number of options to the following executive officers of the Company
with an exercise price equal to the initial public offering price: 63,600 to Mr.
Blecker; 106,000 to Mr. Geritz; 6,300 to Mr. Kingsley; and 8,400 to Mrs.
Blecker. In addition, the Company anticipates granting 253,100 options to
non-executive employees of the Company with an exercise price equal to the
initial public offering price. These options will be subject to a five-year
vesting schedule providing that 20% of such options will vest annually. In
addition, the Company intends to issue 4,200 compensatory options to each of the
three non-employee directors immediately subsequent to the Annual Meeting of
Stockholders in calendar 1998 and immediately following each subsequent Annual
Meeting (to the extent that options remain available therefor under the Stock
Option Plan). These options will vest immediately and have an exercise price
equal to the fair market value of the Common Stock on the date of grant.

      Recognition and Retention Plan and Trust. The Board of Directors of the
Company, on January 22, 1998, adopted the Recognition Plan for directors,
selected officers and employees of the Company, and the stockholders of the
Company, approved such plan by unanimous written consent on January 22, 1998.
The objective of the Recognition Plan is to enable the Company to provide
directors, officers and employees with a proprietary interest in the Company as
an incentive to contribute to its success.

      The Recognition Plan is administered by the Compensation Committee, which
will have the responsibility to hold all Common Stock contributed, or to invest
all funds contributed, to a trust created for the Recognition Plan (the
"Trust"). The Recognition Plan will remain in effect for a period of ten years
or until January 21, 2008, unless it is terminated by the Board of Directors or
all assets of the trust are distributed prior to such date.

      The Company has reserved for issuance 507,000 shares of Common Stock under
the Recognition Plan. The shares, while restricted, may not be sold, pledged or
otherwise disposed of and are required to be held in the Trust. If a recipient
terminates his or her employment for reasons other than death, disability or
retirement, the recipient will forfeit all rights to the allocated shares under
restriction. The Company will indemnify the trustees of the Trust for all
claims, expenses and liabilities arising out of or related to the exercise of
the trustees' powers and the discharge of their duties under the Trust, unless
the same is due to the gross negligence or willful misconduct of the Trustee.
The Trust may purchase from the Company and/or stockholders thereof additional
shares of Common Stock for distribution pursuant to the Recognition Plan. Shares
of Common Stock granted pursuant to the Recognition Plan generally will be in
the form of restricted stock earned at the rate of 20% per year, subject to
continued employment or service as a director, except that all shares will be
deemed earned as of the last day of a recipient's employment as a result of
death or retirement or, in the event and as of the date of, a Change of Control
of the Company, which is defined under the Recognition Plan to mean any change
of control of the Company which would be required to be reported by the Company
under Regulation 14A of the Exchange Act. Recipients of grants under the
Recognition Plan will not be required to make any payment at the time of grant
or when the underlying shares of Common Stock become vested.

      For accounting purposes, compensation expense in the amount of the fair
market value of the Common Stock at the date of the grant to the recipient will
be recognized pro 


                                      -65-
<PAGE>   70
rata over the number of years during which the shares vest. The Board of
Directors of the Company can terminate the Recognition Plan at any time, and if
it does so, any shares not allocated will revert to the Company.

      The Company does not anticipate granting stock awards for shares of Common
Stock to directors, executive officers and other key personnel immediately
subsequent to the consummation of the Offering but may do so thereafter. It is
currently anticipated that stock awards will be made to other officers and key
personnel by the committee primarily based on performance, although the
committee will be able to consider other factors determined to be relevant in
its sole discretion. In addition, pursuant to the Recognition Plan, shares of
Common Stock authorized to be awarded by the Recognition Plan will be available
to be awarded to non-employee directors of the Company pursuant to a formula
that complies with Rule 16b-3 under the Exchange Act. See "Risk Factors -
Substantial Dilution."

      401(k) Plan. The Company has a 401(k) plan for all employees (the "401(k)
Plan"), age 21 or older, with one year of service. The 401(k) Plan is a
contributory defined contribution plan which is intended to qualify under
Section 401(k) of the Code. Participants may contribute to the 401(k) Plan by
salary reduction of up to 20% of annual compensation for the year. Such
contribution defers the employee's earnings up to a maximum of $9,500 in each
plan year, indexed annually. The Company may, in its discretion, determine each
year to make a matching contribution out of current or accumulated net profit
equal to a percentage of the amount deferred by the employee. Although an
employee's contributions to the 401(k) Plan are immediately vested, the matching
contributions made by the Company become vested at the rate of 20% per year upon
the completion of two years of credited service. All funds contributed to the
401(k) Plan are held in a trust maintained by a brokerage firm and investments
are made at the direction of the employee. Contributions by the Company to the
401(k) Plan were $14,898 for fiscal 1997.

      Cafeteria Plan. All Company employees who satisfy the conditions for
coverage under the insurance benefit plans maintained by the Company are
eligible to participate in the Company's Cafeteria Plan, which permits employees
to deduct a portion of their gross wages prior to the calculation of federal
income tax, FICA and Medicare deductions and state income tax, to be used to pay
for the following permissible benefits: group health insurance, life insurance,
disability insurance, cancer plan, vision plan, accidental death, dismemberment
plan, or dental insurance.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

      The Board of Directors established a Compensation Committee on January 22,
1998. The Compensation Committee currently is comprised of Messrs. Beck and
Roush. None of the executive officers of the Company currently serves on the
compensation committee of another entity or on any other committee of the board
of directors of another entity performing similar functions.

                             CERTAIN TRANSACTIONS

PENDING RECAPITALIZATION

      The Company was organized under the laws of the State of Maryland on
December 2, 1998. On January 26, 1998, the Company entered into an Agreement and
Plan of Recapitalization with Mr. Blecker, Mrs. Blecker (collectively the
"Bleckers"), ICARUS Corporation ("ICARUS MD") and ICARUS Services Limited
("ICARUS UK"), providing for the transfer by the Bleckers of all of their shares
of the capital stock of ICARUS MD and ICARUS UK to the Company in exchange for
an aggregate of 2,999,000 shares of Common Stock and 100 shares of Series A
Preferred Stock of the Company (the "Recapitalization"). See "Description of
Capital Stock - Preferred Stock." As a result of the Recapitalization, ICARUS MD
and ICARUS UK will become wholly-owned subsidiaries of the Company. Following
the Recapitalization, ICARUS Nippon will remain a wholly-owned subsidiary of
ICARUS UK, and ICARUS Development and Marketing Corporation will remain a
wholly-owned subsidiary of ICARUS MD. It is anticipated that the
Recapitalization will be consummated immediately prior to the closing of the
Offering.

STOCKHOLDER LOANS TO COMPANY

      During fiscal 1992, Mr. Blecker made two loans to the Company in the
aggregate amounts of $100,000 and $25,000, respectively. The loans were made
pursuant to an unsecured demand promissory note bearing interest at 6.5% per
annum. All amounts outstanding under the loans were fully repaid in January
1997.

FUTURE TRANSACTIONS

      Future transactions between the Company and related parties will be
approved by a majority of all disinterested directors and will be on terms no
less favorable than those which could be obtained from unrelated third parties.

CONTROL BY PRINCIPAL STOCKHOLDER

      Mr. Blecker holds 97.0% of the outstanding Common Stock, and after the
Offering will own approximately 52.9%. Accordingly, Mr. Blecker will, after the
Offering, be in a position to control all matters relating to the Company's
business, including the election of the Company's Board of Directors, the
acquisition or disposition of assets (in the ordinary course of the Company's
business or otherwise), future issuances of Common Stock or other securities of
the Company, and the declaration and payment of dividends on the Common Stock.
In addition, he may be able to prevent, delay or make more difficult any
business combination involving the Company not approved by him. See "Risk
Factors - Control by Principal Stockholders" and "Description of Capital Stock -
Maryland Anti-Takeover Law and Certain Provisions of the Articles of
Incorporation."

      The Principal Stockholders of the Company will benefit from this Offering
in that a public market will be created for shares of the Company's Common
Stock and the Principal Stockholders will have substantial unrealized gain with
respect to shares of the Company's Common Stock owned by them following this
Offering.

LIMITATIONS ON LIABILITY AND INDEMNIFICATION MATTERS

      The Company has adopted provisions in its Articles that eliminate to the
fullest extent permissible under Maryland law the liability of its directors to
the Company or its stockholders for monetary damages except to the extent that
it is proven that the director actually received an improper benefit or profit
in money, property or services or the director's action or failure to act was
the result of active and deliberate dishonesty and was material to the cause of
action adjudicated in the proceeding. This provision is designed to ensure that
the ability of the Company's directors to exercise their best business judgment
in managing the Company's affairs, subject to their continuing fiduciary duties
to the Company and its stockholders, is not unreasonably impeded by exposure to
potentially high personal costs or other uncertainties of litigation.

      The Articles also provide that the Company shall indemnify any person who
was or is a party or is threatened to be made a party to any threatened, pending
or completed action, suit or proceeding, whether civil, criminal, administrative
or investigative, because such person is or was a director, officer, employee or
agent of the Company. Under the terms of the Articles, such indemnification also
will be provided to any person who is or was serving at the request of the
Company as a director, officer, employee, agent or in certain other capacities
of another corporation, partnership, joint venture, trust, employee benefit plan
or certain other enterprises. Such indemnification is furnished to the full
extent provided by law against expenses (including attorneys' fees), judgments,
fines, excise taxes and amounts paid in settlement actually and reasonably
incurred in connection with such action, suit or proceeding. The indemnification
provisions also permit the Company to pay reasonable expenses in advance of the
final disposition of any action, suit or proceeding as authorized by the Board
of Directors, provided that the indemnified person provides a written
affirmation that he or she has met the standards of conduct necessary for
indemnification under applicable law and undertakes to repay the Company if it
is ultimately determined that such person was not entitled to indemnification.

      The rights of indemnification provided in the Company's Articles are not
exclusive of any other rights which may be available under the Articles or
Bylaws of the Company, any insurance or other agreement, by vote of stockholders
or disinterested directors or otherwise. In addition, the Articles authorize the
Company to maintain insurance on behalf of any person who is or was a director,
officer, employee or agent of the Company or with another entity at the request
of the Company, whether or not the Company would have the power to provide
indemnification to such person. The Company intends to obtain director and
officer liability insurance coverage.

      Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
Company pursuant to the foregoing provisions, or otherwise, the Company has been
advised that in the opinion of the Commission such indemnification is against
public policy as expressed in the Securities Act and is therefore unenforceable.

      At the present time, there is no pending litigation or proceeding
involving a director, officer, employee or other agent of the Company in which
indemnification would be required or permitted. The Company is not aware of any
threatened litigation or proceeding which may result in a claim for such
indemnification.

      (1) Beneficial ownership is determined in accordance with the rules of the

                          DESCRIPTION OF CAPITAL STOCK

GENERAL

      The Company is authorized to issue 20,000,000 shares of Common Stock and
5,000,000 shares of Preferred Stock.

COMMON STOCK

      As of January 30, 1998, there were 1,000 shares of Common Stock
outstanding. Upon the Recapitalization, the Company will issue an aggregate of
2,999,000 shares of Common Stock (in addition to 100 shares of Series A
Preferred Stock) to Mr. Blecker and Mrs. Blecker in exchange for all of the
outstanding common stock of ICARUS Corporation and ISL. See "Certain
Transactions - Pending Recapitalization."

      Dividends. Subject to the prior rights of the holders of any shares of
preferred stock that may be outstanding, the Company may pay dividends as
declared from time to time by the Board of Directors out of funds legally
available therefor. The holders of Common Stock will be entitled to receive and
share equally in such dividends as may be declared by the Board of Directors.

      Voting Rights. Except as provided in any resolution or resolutions adopted
by the Board of Directors establishing any series of Preferred Stock, the
holders of Common Stock possess exclusive voting rights in the Company. Each
holder of shares of Common Stock is entitled to one vote for each share held on
all matters voted upon by stockholders.

      Liquidation. Subject to the prior rights of the holders of any shares of
Company Preferred Stock that may be outstanding, in the event of any
liquidation, dissolution or winding up of the Company, whether voluntary or
involuntary, the holders of the Common Stock would generally be entitled to
receive pro rata, after payment of all debts and liabilities of the Company, all
remaining assets of the Company available for distribution.

      Preemptive Rights; Redemption. Holders of the Common Stock do not have any
preemptive rights with respect to any shares of capital stock of the Company. In
addition, the Common Stock is not subject to any redemption provisions.

PREFERRED STOCK

      The Company is authorized to issue 5,000,000 shares of undesignated,
"blank check" Preferred Stock, of which 100 shares of Series A Preferred Stock
will be outstanding following consummation of the Recapitalization. The Board of
Directors has the authority to issue the Preferred Stock in one or more series
and to fix the price, rights, preferences, privileges and restrictions thereof,
including dividend rights, dividend rates, conversion rights, voting rights,
terms of redemption, redemption prices, liquidation preferences and the number
of shares constituting a series or the designation of such series, without any
further vote or action by the Company's stockholders. The Preferred Stock may be
issued in distinctly designated series, may be convertible into Common Stock and
may rank prior to the Common Stock as to dividend rights, liquidation
preferences, or both, and may have full or limited voting rights. Accordingly,
the issuance of Preferred Stock could adversely affect the voting and other
rights of holders of Common Stock.


                                      -70-
<PAGE>   75
      Following consummation of the Recapitalization, there will be 100 shares
of Series A Preferred Stock issued and outstanding and held beneficially and of
record by the Bleckers. The shares of the Series A Preferred Stock rank senior
to the Common Stock as to rights upon liquidation, but are not entitled to any
dividends, are non-redeemable, have no voting rights, no registration rights and
no sinking fund is to be established for their retirement. The Series A
Preferred Stock was issued solely to facilitate the Recapitalization under
applicable law.

      The authorized but unissued shares of Preferred Stock and the authorized
but unissued and unreserved shares of Common Stock are available for issuance in
future mergers or acquisitions, in a future underwritten public offering or
private placement or for other general corporate purposes. Except as otherwise
required to approve a transaction in which the additional authorized shares of
Preferred Stock would be issued or as may be required by the NASD to maintain
the quotation of the Common Stock on the National Association of Securities
Dealers, Inc. Automated Quotation ("Nasdaq") National Market no stockholder
approval would be required for the issuance of these shares. The issuance of
Common or Preferred Stock, while providing desirable flexibility in connection
with possible acquisitions and other corporate purposes, could have the effect
of delaying, deferring or preventing a change in control of the Company without
further action by the stockholders and may adversely affect the market price of,
and the voting and other rights of, the holders of Common Stock. Except for this
Offering, the Recapitalization and shares reserved for issuance pursuant to the
Company's employee stock benefit plans, the Company has no current plans to
issue any shares of Common or Preferred Stock.

MARYLAND ANTI-TAKEOVER LAW AND CERTAIN PROVISIONS OF THE ARTICLES OF
INCORPORATION

      General. The following discussion is a general summary of certain
provisions of the Maryland General Corporation Law and the Articles of the
Company, which may be deemed to have an anti-takeover effect. The following
description of certain of the provisions of the MGCL and the Articles of the
Company is necessarily general and reference should be made in each case to the
Articles which are set forth as an exhibit to the Company's Registration
Statement filed with the Commission and the applicable provisions of the MGCL.
See "Available Information." Capitalized terms not otherwise defined shall have
the meanings set forth in the Articles.

      Maryland General Corporation Law. The MGCL maintains certain provisions
that may have the effect of delaying, deterring or preventing a change of
control of the Company. Section 3-701 and following sections state that control
shares (defined as shares of stock of a corporation owned by a person or as to
which such person is entitled to vote within the ranges of 20% to 33%, 33% or
more but less than 51%, or 51% or more of all voting power) acquired in a
control share acquisition (defined as the acquisition of, or power to vote, such
shares) have no voting rights except to the extent approved by stockholders at a
special meeting called for such purpose by the affirmative vote of two-thirds of
all the votes entitled to be cast on such matter, excluding all shares owned by
the person who acquired such control shares. The corporation that is the target
of a control share acquisition may, at its option, redeem any or all control
shares at their fair value, except for control shares for which voting rights
have been previously approved. In addition, if voting rights for control shares
are approved at a special meeting held in accordance with the statute and the
acquiring person is entitled to exercise or direct the exercise of a majority or
more of all voting power, all stockholders of the corporation (other than the
acquiring person) have the 


                                      -71-
<PAGE>   76
right to object to such action and seek from the Company payment of fair value
for their shares, which amount may not be less than the highest price paid by
the acquiring person for his or her shares in the control share acquisition.
This statute may have the effect of discouraging persons from acquiring large
blocks of Company Common Stock. Article X.D. of the Company's Articles expressly
excludes the Blecker Interest, as defined therein, from the operation of these
provisions.

      Section 3-603 of the MGCL also contains a provision which is substantially
similar to Article X of the Articles relating to business combinations with
related persons. The Company has elected not to be governed by this provision of
the MGCL.

      Nominations and Stockholder Proposals. Article VII.D. of the Company's
Articles governs nominations for election to the Board of Directors, and
requires all nominations for election to the Board of Directors other than those
made by the Board to be made by a stockholder who has complied with the notice
provisions of such section. Article IX.C. of the Articles provides that only
such business as shall have been properly brought before an annual meeting of
stockholders shall be conducted at the annual meeting. Business may be brought
before the meeting by or at the direction of the Board of Directors or otherwise
must be properly brought before the meeting by a stockholder. For business to be
properly brought before an annual meeting by a stockholder, the stockholder must
have given timely notice thereof in writing to the Secretary of the Company. In
both instances, written notice of a stockholder nomination or stockholder
proposal must be communicated to the attention of the Company's Secretary and
either delivered to, or mailed and received at, the principal executive offices
of the Company for the first annual meeting after the filing of the Articles,
before the close of business on the tenth day following the date on which notice
of such meeting is first given to stockholders, and thereafter, not less than 60
days prior to the anniversary date of the mailing of proxy materials by the
Company in connection with the immediately preceding annual meeting of
stockholders of the Company. Each such notice shall include specified matters
set forth in the Articles.

      The procedures regarding stockholder nominations and stockholder proposals
will provide the Board of Directors with the information which will be necessary
to evaluate a stockholder nominee to the Board and stockholder proposals and
other relevant information, such as existing stockholder support for a nominee
or business proposal, as well as the time necessary to consider and evaluate
such information in advance of the applicable meeting.

      Special Meetings of Stockholders. Article IX of the Company's Articles
provides that special meetings of the Company's stockholders, for any purpose or
purposes, may only be called by the Chairman of the Board, the President or a
majority of the whole Board of Directors and a majority of the Continuing
Directors (generally, those directors at the time of effectiveness of the
Articles and those directors who are not affiliated with the Related Person and
who are elected as directors prior to the time the Related Person (as defined
below) became such, or those directors who are unaffiliated with a Related
Person and who are designated as Continuing Directors before their initial
election by a majority of the other Continuing Directors), or by holders of not
less than majority of all votes entitled to be cast on any issue proposed to be
considered at such special meeting. A "Related Person" is defined generally to
include any person, partnership, corporation, group or other entity (other than
Mr. Blecker, Mrs. Blecker or any of Mr. Blecker's relatives, or the Company) who
is the beneficial owner of 10% or more of the shares of the Company entitled to
vote 


                                      -72-
<PAGE>   77
generally in an election of directors ("Voting Shares"). This provision will
make it more difficult for stockholders to take action opposed by the Board of
Directors.

      Business Combinations. Article X of the Articles governs any proposed
"Business Combination" (defined generally to include certain sales, purchases,
exchanges, leases, transfers, dispositions or acquisitions of assets, mergers or
consolidations, or certain reclassifications of securities of the Company)
between the Company, on the one hand, and a Related Person, on the other hand.

      In general, Article X provides that if certain specified conditions are
not met, then the Company may not become a party to any Business Combination
without the prior affirmative vote at a meeting of the Company's stockholders by
the holders of at least 80% of the Voting Shares, voting separately as a class,
and by an Independent Majority of Stockholders (generally, the holders of a
majority of the outstanding Voting Shares that are not beneficially owned,
directly or indirectly, by a Related Person or any affiliate or associate
thereof). If such approval were obtained, the specified conditions would not
have to be met. Such conditions also would not have to be met if the Board of
Directors approved the Business Combination.

      Article X is intended to provide minimum safeguards for stockholders who
do not accept a takeover attempt and continue to hold their shares after the
attempt succeeds and the control of the Company is required by a Related Person.

      However, Article X would not restrict another company that merely desired
to exercise control over the Company and did not intend to effect a subsequent
Business Combination. Moreover, these provisions may not apply to an attempted
combination with a person not a Related Person, including Mr. Blecker, Mrs.
Blecker or any "Blecker Interest" (generally, descendants of Mr. Blecker or any
person holding Voting Shares for the benefit of Mr. Blecker, Mrs. Blecker or the
descendants of Mr. Blecker). If, however, another company obtaining control over
the Company were not willing to meet the price and other conditions of Articles
X, the holders of more than one-fifth of the outstanding Voting Shares could
block a Business Combination supported by the remaining stockholders. The result
is that Business Combinations favored by a majority of stockholders might not be
approved. Article X might also discourage a tender offer for the Company's stock
because of the resulting need either to observe the minimum price requirements
or to obtain an 80% stockholder vote as a precondition to any subsequent
Business Combination. This might have the effect of preventing temporary
fluctuations in the market price of the stock of the Company that could result
from actual or rumored takeover attempts.

      Amendment of Articles. Article XI of the Company's Articles provides that
any amendment of the Articles must be first approved by a majority of the Board
of Directors and thereafter by the holders of two-thirds of the shares of the
Company entitled to vote in an election of directors, but the approval of 75% of
the shares of the Company entitled to vote in an election of directors is
required for any amendment to Articles VI (pre-emptive rights), VII (directors),
VIII (indemnification), IX (relating to meetings of stockholders), and XI
(amendments to the Articles and Bylaws). In addition, Article X.E. of the
Company's Articles provides that Article X may not be changed, amended or
repealed without the affirmative vote of the holders of at least 80% of the
Voting Shares and by an Independent Majority of Stockholders. However, any
change, amendment or repeal to Article X of the Company's Articles approved by
two-thirds of the whole Board


                                      -73-
<PAGE>   78
of Directors and a majority of the Continuing Directors is not subject to the
approval requirements of Article X.E.

      Anti-Takeover Effects. The Board of Directors believes that the foregoing
provisions in the Articles are prudent and, together with applicable state law,
will reduce vulnerability to takeover attempts and certain other transactions
that are not negotiated with and approved by the Board of Directors of the
Company. The Board of Directors believes that these provisions are in the best
interests of the Company and its stockholders. In the Board of Directors'
judgment, the Board of Directors is in the best position to determine the true
value of the Company and to negotiate more effectively for what may be in the
best interests of its stockholders. Accordingly, the Board of Directors believes
that it is in the best interests of the Company and its current and future
stockholders to encourage potential acquirors to negotiate directly with the
Board of Directors and that these provisions will encourage such negotiations
and discourage hostile takeover attempts. It is also the Board of Directors'
view that these provisions should not discourage persons from proposing a merger
or other transaction at prices reflective of the true value of the Company and
where the transaction is in the best interests of all stockholders.

      Despite the Board of Directors' belief as to the benefits to the Company's
stockholders of the foregoing provisions, these provisions also may have the
effect of discouraging a future takeover attempt in which stockholders might
receive a substantial premium for their shares over then current market prices.
As a result, stockholders who might desire to participate in such a transaction
may not have an opportunity to do so. The Board of Directors, however, has
concluded that the potential benefits of these provisions outweigh their
possible disadvantages. The Board of Directors of the Company is not currently
aware of any effort that might be made to acquire control of the Company.

      Certain Benefit Plan Provisions. In addition to the above provisions, the
Company's Stock Option Plan provides that, in the event of a change in control
of the Company, any outstanding options would become immediately exercisable.
The Company's Recognition Plan also provides that in the event of any change in
control of the Company, all shares of Common Stock subject to a plan share award
shall be deemed earned as of the date of the Change of Control. Such provisions,
to the extent they increase the cost of any acquisition of control, could be
deemed to have an anti-takeover effect. See "Management - Stock Plans - 1998
Stock Option Plan" and "Recognition and Retention Plan and Trust."

TRANSFER AGENT AND REGISTRAR

      The transfer agent and registrar for the Common Stock is Registrar and
Transfer Company, Cranford, New Jersey.


                         SHARES ELIGIBLE FOR FUTURE SALE

      Prior to the Offering, there has been no market for the Common Stock of
the Company. Sales of substantial shares of Common Stock in the public market
following this Offering could adversely affect the market price of the Common
Stock prevailing from time to time.


                                      -74-
<PAGE>   79
      Upon completion of this Offering, the Company will have 5,500,000 shares
of Common Stock outstanding. Of these shares, all of the shares sold in this
Offering will be freely transferable without restriction or registration under
the Securities Act, except for any shares purchased by an existing "affiliate"
of the Company as that term is defined by the Securities Act (an "Affiliate"),
which shares will be subject to the resale limitations of Rule 144 adopted under
the Securities Act. On the date of this Prospectus, 3,000,000 "control shares"
as defined in Rule 144 will be outstanding. All of said shares will become
available for sale in reliance upon Rule 144 one year after the date of the
Recapitalization.

      The Company and each of the Principal Stockholders have agreed not to
offer, pledge, sell, contract to sell, sell any option or contract to purchase,
purchase any option or contract to sell, grant any option, right or warrant to
purchase, or otherwise transfer or dispose of, directly or indirectly, any
shares of Common Stock or any securities convertible into or exercisable or
exchangeable for Common Stock, or enter into any swap or similar agreement that
transfers, in whole or in part, the economic risk of ownership of the Common
Stock, for a period of 180 days after the date of this Prospectus, without the
prior written consent of Hoak Breedlove Wesneski & Co. Hoak Breedlove Wesneski &
Co. may, in its sole discretion and at any time without notice, release all or
any portion of the securities subject to the lock-up agreements. 

      In general, under Rule 144 as currently in effect, beginning 90 days after
the date of this Prospectus, a person (or persons whose shares are aggregated)
who has beneficially owned restricted securities for at least one year
(including the holding period of any prior owner except an affiliate of the
Company) would be entitled to sell within any three-month period a number of
shares that does not exceed the greater of: (i) one percent of the number of
shares of Common Stock then outstanding; or (ii) the average weekly trading
volume of the Common Stock during the four calendar weeks preceding the filing
of a Form 144 with respect to such sale. Sales under Rule 144 are also subject
to certain manner of sale provisions and notice requirements and to the
availability of current public information about the Company. Under Rule 144(k),
a person who is not deemed to have been an Affiliate 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
except an Affiliate), is entitled to sell such shares without complying with the
manner of sale, public information, volume limitation or notice provisions of
Rule 144. Subject to the contractual restrictions described above, "144(k)
shares" may therefore be sold immediately upon the completion of this Offering.

      Subject to certain limitations on the aggregate offering price of a
transaction and other conditions, Rule 701 may be relied upon with respect to
the resale of securities originally purchased from the Company by its employees,
directors, officers, consultants or advisors prior to the date the issuer
becomes subject to the reporting requirements of the Exchange Act, pursuant to
written compensatory benefit plans or written contracts relating to the
compensation of such persons. In addition, the Commission has indicated that
Rule 701 will apply to typical stock options granted by an issuer before it
becomes subject to the reporting requirements of the Exchange Act, along with
the shares acquired upon exercise of such options (including exercises after the
date of this Prospectus). Securities issued in reliance on Rule 701 are
restricted securities and, subject to the contractual restrictions described
above, beginning 90 days after the date of this Prospectus, may be sold by
persons other 


                                      -75-
<PAGE>   80
than Affiliates subject only to the manner of sale provisions of Rule 144 and by
Affiliates under Rule 144 without compliance with its two-year minimum holding
period requirements.

      The Company anticipates that prior to the date of this Prospectus, options
to purchase 437,400 shares of Common Stock will be outstanding. Shortly after
this Offering, the Company intends to file a registration statement on Form S-8
under the Securities Act covering shares of Common Stock reserved for issuance
under the Company's stock plans. See "Management - Executive Compensation -
Stock Plans." Shares of Common Stock issued upon exercise of options under the
Form S-8 will be available for sale in the public market, subject to Rule 144
volume limitations applicable to Affiliates and subject to the contractual
restrictions described above. The options to be granted will vest annually over
a five-year period.

                                  UNDERWRITING

      The Underwriters named below, represented by Hoak Breedlove Wesneski & Co.
(the "Representative"), have severally agreed, subject to the terms and
conditions contained in the underwriting agreement (the "Underwriting
Agreement"), by and between the Company and the Underwriters, to purchase from
the Company the number of shares of Common Stock indicated below opposite their
respective names, at the initial public offering price less the underwriting
discount set forth on the cover page of this Prospectus. The Underwriting
Agreement provides that the obligations of the Underwriters are subject to
certain conditions precedent and that the Underwriters are committed to
purchase all of the shares of Common Stock if they purchase any.

</TABLE>

      The Representative has advised the Company that the Underwriters propose 
initially to offer the shares of Common Stock to the public on the terms set
forth on the cover page of this Prospectus. The Underwriters may allow to
selected dealers a concession of not more than $______________ per share; and
the Underwriters may allow, and such dealers may reallow, a concession of not
more than $_____________ per share to certain other dealers. After the
Offering, the public offering price and other selling terms may be changed by
the Representative. The Common Stock is offered subject to receipt and
acceptance by the Underwriters, and to certain other conditions, including the
right to reject orders in whole or in part.

      The Company has granted an option to the Underwriters, exercisable during
the 30-day period after the date of this Prospectus, to purchase up to a maximum
of 375,000 additional shares of Common Stock, to cover over-allotments, if any,
at the same price per share as the initial shares to be purchased by the
Underwriters. To the extent that the 


                                      -76-
<PAGE>   81
Underwriters exercise this option, the Underwriters will be committed, subject
to certain conditions, to purchase such additional shares in approximately the
same proportion as set forth in the above table. The Underwriters may purchase
such shares only to cover over-allotments made in connection with this Offering.

      The Underwriting Agreement provides that the Company will indemnify the 
Underwriters against certain liabilities, including civil liabilities under the
Securities Act, or will contribute to payments the Underwriter may be required
to make in respect thereof.

      The Principal Stockholders have agreed that, for a period of 180 days from
the date of this Prospectus, they will not offer, sell or otherwise dispose of
any shares of their Common Stock or options to acquire shares of Common Stock
without the prior written consent of Hoak Breedlove Wesneski & Co. The Company
has agreed not to sell any shares of Common Stock or any other securities
convertible into shares of Common Stock for a period of 180 days from the date
of this Prospectus without the prior written consent of Hoak Breedlove Wesneski
& Co., except that the Company may, without consent, grant stock options
pursuant to the Company's stock option plans or issue shares of Common Stock
upon exercise of outstanding stock options.

      The Representative has informed the Company that the Underwriters do not
expect to make sales of Common Stock offered by this Prospectus to accounts over
which they exercise discretionary authority in excess of 5% of the shares of
Common Stock offered hereby.

      Prior to the Offering, there has been no public market for the Common
Stock. The initial public offering price for the Common Stock will be
determined by negotiations between the Company and the Representative. Among
the factors to be considered in determining the initial public offering price
are prevailing market and economic conditions, revenues and earnings of the
Company, market valuations of other companies engaged in activities similar to
the Company, estimates of the business potential and prospects of the Company,
the present state of the Company's business operations, the Company's
management and other factors deemed relevant. The estimated initial public
offering price range set forth on the cover of this preliminary prospectus is
subject to change as a result of market conditions and other factors.

      Certain persons participating in this Offering may overallot or effect
transactions which stabilize, maintain or otherwise affect the market price of
the Common Stock at levels above those which might otherwise prevail in the open
market, including by entering stabilizing bids, effecting syndicate covering
transactions or imposing penalty bids. A stabilizing bid means the placing of
any bid or effecting of any purchase, for the purpose of pegging, fixing or
maintaining the price of the Common Stock. A syndicate covering transaction
means the placing of any bid on behalf of the underwriting syndicate or the
effecting of any purchase to reduce a short position created in connection with
the Offering. A penalty bid means an arrangement that permits the Underwriters
to reclaim a selling concession from a syndicate member in connection with the
Offering when shares of Common Stock sold by the syndicate member are purchased
in syndicate covering transactions. Such transactions may be effected on the
Nasdaq National Market, or otherwise. Such stabilizing, if commenced, may be
discontinued at any time.

      The Company, which is not currently a reporting company, has filed with

REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS


Board of Directors
ICARUS International, Inc.


We have audited the accompanying consolidated balance sheet of ICARUS
International, Inc. (the Company) as of April 30, 1997, and the related
consolidated statements of operations, changes in stockholders' equity and cash
flows for the years ended April 30, 1997 and 1996. These financial statements
are the responsibility of the Company's management. Our responsibility is to
express an opinion on these financial statements based on our audits.

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

In our opinion, the consolidated financial statements present fairly, in all
material respects, the consolidated financial position of ICARUS International,
Inc., as of April 30, 1997, and the results of its operations and its cash flows
for the years ended April 30, 1997 and 1996, in conformity with generally
accepted accounting principles.

Notes to Consolidated Financial Statements

NOTE A--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    A summary of the significant accounting principles applied in the
    preparation of the consolidated financial statements follows:

    FORMATION OF HOLDING COMPANY AND RECAPITALIZATION

    ICARUS International, Inc., was formed December 2, 1997, to be a newly
    created holding company for its two wholly owned subsidiaries, ICARUS
    Corporation (a Maryland corporation) and ICARUS Services, Limited (a United
    Kingdom private limited company). ICARUS International, Inc., and its
    subsidiaries are collectively referred to herein as "the Company." In
    conjunction with the filing of a registration statement relating to an
    initial public offering (see Note K), and immediately prior to the effective
    date of such offering, Icarus International, Inc., will issue an aggregate
    of 2,999,000 shares of a total of 20,000,000 newly authorized shares of
    common stock, and 100 shares of a total of 5,000,000 newly authorized
    preferred stock, in exchange for all the outstanding shares of capital stock
    of the subsidiaries (the Recapitalization).

    The accompanying financial statements, including stockholders' equity and
    per share amounts, give retroactive effect to the Recapitalization for all
    periods presented.

    NATURE OF OPERATIONS

    The Company develops and markets project modeling software and services
    internationally. The Company's principal products are used in the conceptual
    design, estimating, scheduling, cost determination and cost tracking in the
    construction of facilities in chemical processing, energy producing,
    petrochemical, pharmaceutical, food, pulp and paper and related industries.
    The Company's services include maintenance, application consulting services
    on a contract basis and training courses.

    PRINCIPLES OF CONSOLIDATION

    The accompanying consolidated financial statements include the accounts of
    ICARUS International, Inc., and its wholly owned subsidiaries. Significant
    intercompany accounts and transactions have been eliminated.

    INTERIM REPORTING

    The accompanying condensed financial information as of October 31, 1997, and
    for the six months ended October 31, 1996, and 1997, including such
    information included in the Notes to Consolidated Financial Statements and
    disclosures regarding matters occurring after April 30, 1997, is unaudited.
    In the opinion of management, all adjustments, consisting only of normal
    recurring adjustments, considered necessary for a fair presentation have
    been included. Operating results for any interim period are not necessarily
    indicative of the results for any other interim period or for an entire
    year.

    CASH AND CASH EQUIVALENTS

    Cash and cash equivalents are stated at cost, which approximates market, and
    consists of short-term, highly liquid investments with original maturities
    of less than three months.

NOTE A--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES--CONTINUED


    FAIR VALUE OF FINANCIAL INSTRUMENTS

    The recorded amounts of cash and cash equivalents, accounts receivable and
    accounts payable at April 30, 1997, approximate fair value in accordance
    with Statement of Financial Accounting Standards (SFAS) No. 107,
    "Disclosures About Fair Value of Financial Instruments," due to the
    relatively short period of time between origination of the instruments and
    their expected realization.

    DEPRECIATION AND AMORTIZATION

    The Company provides for depreciation and amortization, computed using the
    straight-line and declining-balance methods, by charges to operations in
    amounts estimated to allocate the cost of the assets over their estimated
    useful lives as follows:

                                                   ESTIMATED
          ASSET CLASSIFICATION                     USEFUL LIFE

          Computer equipment                       3-5 Years
          Purchased software programs              3 Years
          Furniture and fixtures                   7 Years
          Leasehold improvements                   Life of Lease

    REVENUE RECOGNITION

    The Company recognizes revenue from product licensing agreements in
    accordance with the American Institute of Certified Public Accountants
    Statement of Position No. 91-1, "Software Revenue Recognition" (SOP 91-1).

    The Company typically licenses its products pursuant to single-year and
    multi-year noncancelable agreements. Revenue from software license
    agreements is recognized upon execution of a contract and shipment of the
    software, provided that no significant vendor obligations remain and
    collection is probable. For recurring one-year license fees, revenue is
    recognized on the contract renewal date. For multi-year agreements, revenue
    is recognized ratably over the multi-year period on each successive
    anniversary date. Customer payment terms vary. Amounts collected in advance
    of satisfying revenue recognition criteria are classified as current and
    long-term deferred revenue in the accompanying balance sheets.

    Maintenance fee revenue is recognized ratably over the support period, which
    is generally one year. Such revenue includes amounts bundled with initial
    license fee arrangement for which separate prices have been derived based
    upon the Company's historical retail pricing for separate arrangements.

    Consulting and training revenue is recognized as the related services are
    performed.

    Accounts receivable arising from sale of software license agreements,
    maintenance, training and other services are due from customers 30 days from
    the date invoiced. Provision for returns and uncollectible accounts has been
    determined based upon the Company's past experience.

    COMPUTER SOFTWARE DEVELOPMENT COSTS

    Development costs relating to new software products and enhancements to
    existing software products are expensed as incurred until technological
    feasibility has been established, after which additional costs would be
    capitalized in accordance with SFAS No. 86, "Accounting for the Costs of
    Computer Software to Be Sold, Leased or Otherwise Marketed." Historically,
    the Company has not incurred material software development costs following
    the establishment of technological feasibility, and therefore no costs
    have been capitalized as of October 31, 1997.

    RESEARCH AND DEVELOPMENT COSTS

    The Company expenses research and development costs as incurred, including
    costs relating to strategic technology arrangements.

    FOREIGN CURRENCY TRANSLATION

    The financial position and results of operations of the Company's foreign
    affiliates are translated using the local currency as the functional
    currency. Assets and liabilities of the affiliates are translated at the
    exchange rate in effect at year-end. Income statement accounts are
    translated at the average rate of exchange rates prevailing during the year.
    Translation adjustments arising from the use of differing exchange rates
    from period to period are included in the cumulative translation adjustment
    account in stockholders' equity. Gains and losses resulting from foreign
    currency transactions are included in operations and are not material for
    any of the periods presented.

    STOCK-BASED COMPENSATION COSTS

    SFAS No. 123, "Accounting for Stock-Based Compensation," encourages but does
    not require companies to record stock-based employee compensation plans at
    their fair value. The Company has elected to account for stock-based
    compensation using the intrinsic value method prescribed in Accounting
    Principles Board (APB) Opinion No. 25, "Accounting for Stock Issued to
    Employees," and related interpretations. Accordingly, compensation cost for
    employee stock options is measured as the excess, if any, of the quoted
    market price of the Company's stock at the date of the grant over the
    exercise price an employee must pay to acquire the stock.

    EARNINGS PER SHARE

    Earnings per share are based on the weighted-average common shares
    outstanding in each year including the effect of common stock equivalents
    and all stock options issued within one year prior to, and in conjunction
    with, the Company's initial public offering.

    RECENTLY ISSUED ACCOUNTING STANDARDS

    The Financial Accounting Standards Board recently issued three new
    accounting standards that will affect the Company's financial reporting
    methods. Under SFAS No. 128, the Company will be required to prospectively
    change the method used to compute fully diluted earnings per share; however,
    the impact is not expected to be material. Under SFAS No. 130, the Company
    will be required to display an amount representing total comprehensive
    income and its components in the financial statements. Reclassification of
    financial statements for earlier periods provided for comparative purposes
    is required. Under SFAS No. 131, the Company will be required to report
    certain information about its operating segments in its interim and annual
    financial statements, and certain information about its products and
    services, the geographic areas where it operates and its major customers. In
    the initial year of application, comparative information for earlier years
    is to be restated. SFAS No. 128 is effective for the Company's fiscal year
    1998, and SFAS Nos. 130 and 131 are effective for the Company's fiscal year
    1999.

    The American Institute of Certified Public Accountants released Statement of
    Position 97-2 "Software Revenue Recognition" (SOP 97-2), which supersedes
    SOP 91-1. The new SOP 97-2 will be effective for all transactions entered
    into by the Company in fiscal year 1999. The new SOP 97-2 requires, among
    other things, that revenue should be recognized when there is persuasive
    evidence of an existing arrangement, delivery has occurred, the fees charged
    are fixed or determinable and collectibility is probable. Additionally, SOP
    97-2 provides further that for those arrangements which consist of multiple
    elements such as upgrades, enhancements and post-contract support, the fees
    charged must be allocated to each element of the arrangement based upon
    vendor-specific objective evidence of fair value, which is limited to a
    price charged when the element is sold separately or the price for the
    element established by management being the relevant authority. The Company
    currently recognizes revenue on license agreements when all the conditions
    described above have been met, and revenue on multi-year license agreements
    typically is not recognized until such time that payments from customers
    becomes due (the anniversary date). Additionally, the Company historically
    has allocated fees between elements of its arrangements based upon
    established prices charged for those elements when sold separately. In
    management's opinion, the impact of SOP 97-2 is not expected to be material.

    USING ESTIMATES IN PREPARING FINANCIAL STATEMENTS

    In preparing financial statements in conformity with generally accepted
    accounting principles, management is required to make estimates and
    assumptions that affect the reported amounts of assets and liabilities and
    the disclosure of contingent assets and liabilities at the date of the
    financial statements and revenue and expenses during the reporting period.
    Actual results could differ from those estimates.

    RECLASSIFICATIONS

    Certain amounts in the 1996 have been reclassified to conform to 1997
    presentations.

NOTE A--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES--CONTINUED

    CONCENTRATION OF REVENUE IN THE CHEMICAL AND PETROLEUM REFINING INDUSTRIES

    The Company derives a substantial majority of its revenue from software
    licenses to companies in the chemical and petroleum refining industries,
    which are highly cyclical. Accordingly, the Company's future success is
    dependent upon the continued demand for computer-aided chemical engineering
    software by companies in these industries. The Company believes that
    economic downturns in the United States, Europe, Japan and Asia and pricing
    pressures experienced by chemical and petroleum companies in connection with
    cost containment measures have led to delays and reductions in certain
    capital and operating expenditures by many of such companies worldwide. The
    Company's revenue has in the past been, and may in the future be, subject to
    substantial period-to-period fluctuations as a consequence of such industry
    patterns, general domestic and foreign economic conditions and other factors
    affecting spending in the chemical and petroleum refining industries. There
    can be no assurance that such factors will not have a material, adverse
    effect on the Company's business, operating results and financial condition.

    exceeding the limit remain vested and payable, but no further accrual will
    result for any employee until the individual's leave balance falls below the
    limit.

</TABLE>

    STRATEGIC TECHNOLOGY ALLIANCES

    The Company has entered into strategic technology alliances with various
    organizations which provide for the integration of complementary
    technologies to create new products and marketing capabilities. The terms of
    the alliances vary, but generally provide for each participant's funding of
    its own research and development and marketing costs and the ultimate
    sharing of new product revenue and commissions. Expenses incurred by the
    Company during the year ended April 30, 1997, and the six months ended
    October 31, 1997, were $-0- and approximately $53,000, respectively. Revenue
    and commissions totaling $3,670 have been earned by the Company through
    October 31, 1997.

    LITIGATION

    In the normal course of business operations, the Company is periodically
    involved in litigation. Management is of the opinion that the outcome of
    such pending litigation would not have a material impact on the Company's
    financial statements.

NOTE H--INCOME TAXES

    The Company provides deferred income taxes for temporary differences between
    assets and liabilities recognized for financial reporting purposes and
    income tax purposes. The income tax effects of the temporary differences
    result primarily from the use of accrual basis for financial reporting
    purposes and cash basis methods for income tax filings, net operating loss
    carryforwards and the use of different tax year-ends in the United Kingdom.

    The tax effect of significant temporary differences that gave rise to
    deferred income taxes as of April 30, 1997, is as follows:

      money, property, or services; or

         (iii) In the case of any criminal proceeding, the director had
      reasonable cause to believe that the act or omission was unlawful.

        (2)(i) Indemnification may be against judgments, penalties, fines,
      settlements, and reasonable expenses actually incurred by the director in
      connection with the proceeding.

           (ii) However, if the proceeding was one by or in the right of the
      corporation, indemnification may not be made in respect of any proceeding
      in which the director shall have been adjudged to be liable to the
      corporation.

        (3)(i) The termination of any proceeding by judgment, order, or
      settlement does not create a presumption that the director did not meet
      the requisite standard of conduct set forth in this subsection.

           (ii) The termination of any proceeding by conviction, or a plea of
      nolo contendere or its equivalent, or an entry of an order of probation
      prior to judgment, creates a rebuttable presumption that the director did
      not meet that standard of conduct.

                                     II-2

      (c) A director may not be indemnified under subsection (B) of this section
      in respect of any proceeding charging improper personal benefit to the
      director, whether or not involving action in the director's official
      capacity, in which the director was adjudged to be liable on the basis
      that person benefit was improperly received.

      (d) Unless limited by the charter:

      (1) A director who has been successful, on the merits or otherwise, in the
   defense of any proceeding referred to in subsection (B) of this section shall
   be indemnified against reasonable expenses incurred by the director in
   connection with the proceeding.

      (2) A court of appropriate jurisdiction upon application of a director and
   such notice as the court shall require, may order indemnification in the
   following circumstances:

           (i) If it determines a director is entitled to reimbursement under
      paragraph (1) of this subsection, the court shall order indemnification,
      in which case the director shall be entitled to recover the expenses of
      securing such reimbursement; or

           (ii) If it determines that the director is fairly and reasonably
      entitled to indemnification in view of all the relevant circumstances,
      whether or not the director has met the standards of conduct set forth in
      subsection (b) of this section or has been adjudged liable under the
      circumstances described in subsection (c) of this section, the court may
      order such indemnification as the court shall deem proper. However,
      indemnification with respect to any proceeding by or in the right of the
      corporation or in which liability shall have been adjudged in the
      circumstances described in subsection(c) shall be limited to expenses.

      (3) A court of appropriate jurisdiction may be the same court in which the
   proceeding involving the director's liability took place.

      (e)(1) Indemnification under subsection (b) of this section may not be
   made by the corporation unless authorized for a specific proceeding after a
   determination has been made that indemnification of the director is
   permissible in the circumstances because the director has met the standard of
   conduct set forth in subsection (b) of this section.

      (2)  Such determination shall be made:

           (i) By the board of directors by a majority vote of a quorum
      consisting of directors not, at the time, parties to the proceeding, or,
      if such a quorum cannot be obtained, then by a majority vote of a
      committee of the board consisting solely of two or more directors not, at
      the time, parties to such proceeding and who were duly designated to act
      in the matter by a majority vote of the full board in which the designated
      directors who are parties may participate;

           (ii) By special legal counsel selected by the board of directors or a
      committee of the board by vote as set forth in subparagraph (i) of this
      paragraph, or, if the 

                                     II-3
<PAGE>   106

      requisite quorum of the full board cannot be obtained therefor and the
      committee cannot be established, by a majority vote of the full board in
      which director who are parties may participate; or

           (iii) By the stockholders.

      (3) Authorization of indemnification and determination as to
   reasonableness of expenses shall be made in the same manner as the
   determination that indemnification is permissible. However, if the
   determination that indemnification is permissible is made by special legal
   counsel, authorization of indemnification and determination as to
   reasonableness of expenses shall be made in the manner specified in
   subparagraph (ii) of paragraph (2) of this subsection for selection of such
   counsel.

      (4) Shares held by directors who are parties to the proceeding may not be
   voted on the subject matter under this subsection.

      (f)(1) Reasonable expenses incurred by a director who is a party to a
      proceeding may be paid or reimbursed by the corporation in advance of the
      final disposition of the proceeding upon receipt by the corporation of:

           (i) A written affirmation by the director of the director's good
      faith belief that the standard of conduct necessary for indemnification by
      the corporation as authorized in this section has been met; and

           (ii) A written undertaking by or on behalf of the director to repay
      the amount if it shall ultimately be determined that the standard of
      conduct has not been met.

      (2) The undertaking required by subparagraph (ii) of paragraph (1) of this
   subsection shall be an unlimited general obligation of the director but need
   not be secured and may be accepted without reference to financial ability to
   make the repayment.

      (3) Payments under this subsection shall be made as provided by the
   charter, bylaws, or contract or as specified in subsection (e) of this
   section.

      (g) The indemnification and advancement of expenses provided or authorized
   by this section may not be deemed exclusive of any other rights, by
   indemnification or otherwise, to which a director may be entitled under the
   charter, the bylaws, a resolution of stockholders or directors, an agreement
   or otherwise, both as to action in an official capacity and as to action in
   another capacity while holding such office.

      (h) This section does not limit the corporation's power to pay or
   reimburse expenses incurred by a director in connection with an appearance as
   a witness in a proceeding at a time when the director has not been made a
   named defendant or respondent in the proceeding.

        (i)  For purposes of this section:

                                     II-4


<PAGE>   107




      (1) The corporation shall be deemed to have requested a director to serve
   an employee benefit plan where the performance of the director's duties to
   the corporation also imposes duties on, or otherwise involves services by,
   the director to the plan or participants or beneficiaries of the plan;

      (2) Excises taxes assessed on a director with respect to an employee
   benefit plan pursuant to applicable law shall be deemed fines; and

      (3) Action taken or omitted by the director with respect to an employee
   benefit plan in the performance of the director's duties for a purpose
   reasonably believed by the director to be in the interest of the participants
   and beneficiaries of the plan shall be deemed to be for a purpose which is
   not opposed to the best interests of the corporation.

      (j)  Unless limited by the charter:

      (1) An officer of the corporation shall be indemnified as and to the
   extent provided in subsection (d) of this section for a director and shall be
   entitled, to the same extent as a director, to seek indemnification pursuant
   to the provisions of subsection (d);

      (2) A corporation may indemnify and advance expenses to an officer,
   employee, or agent of the corporation to the same extent that it may
   indemnify directors under this section; and

      (3) A corporation, in addition, may indemnify and advance expenses to an
   officer, employee, or agent who is not a director to such further extent,
   consistent with law, as may be provided by its charter, bylaws, general or
   specific action of its board of directors or contract.

      (k)(1) A corporation may purchase and maintain insurance on behalf of any
   person who is or was a director, officer, employee, or agent of the
   corporation, or who, while a director, officer, employee, or agent of the
   corporation, is or was serving at the request of the corporation as a
   director, officer, partner, trustee, employee, or agent of another foreign or
   domestic corporation, partnership, joint venture, trust, other enterprise, or
   employee benefit plan against any liability asserted against and incurred by
   such person in any such capacity or arising out of such person's position,
   whether or not the corporation would have the power to indemnify against
   liability under the provisions of this section.

      (2) A corporation may provide similar protection, including a trust fund,
   letter of credit, or surety bond, not inconsistent with this section.

      (3) The insurance or similar protection may be provided by a subsidiary or
   an affiliate of the corporation.

        (l) Any indemnification of, or advance of expenses to, a director in
   accordance with this section, if arising out of a proceeding by or in the
   right of the corporation, shall be 

                                     II-5


<PAGE>   108

      reported in writing to the stockholders with the notice of the next
      stockholders' meeting or prior to the meeting."

   The Articles of Incorporation ("Articles") of the Company also limit the
liability of, and provide indemnification to, directors and officers of the
Company. Article VIII of the Company's Articles states:

   "A. Limitation of Liability. No director who has performed his or her duties
in accordance with the standard set forth in Section 2-405.1 of the MGCL (or any
successor provision thereto) shall be personally liable to the Corporation or
its stockholders for monetary damages for any act or omission by such director
as a director; provided that a director's liability shall not be limited or
eliminated to the extent that: (i) it is proved that the director actually
received an improper benefit or profit in money, property or services for the
amount of the benefit or profit in money, property or services actually
received; or (ii) a judgment or other final adjudication adverse to the director
is entered in a proceeding based on a finding in the proceeding that the
director's action, or failure to act, was the result of active and deliberate
dishonesty and was material to the cause of action adjudicated in the
proceeding. No amendment to or repeal of this Article VIII.A. shall apply to or
have any effect on the liability or alleged liability of any director of the
Corporation for or with respect to any acts or omissions of such director
occurring prior to such amendment.

   B. Indemnification. The Corporation shall indemnify any person who was or is
a party or is threatened to be a made a party to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative,
arbitrative or investigative, by reason of the fact that such person is or was a
director, officer, employee or agent of the Corporation, or is or was serving at
the request of the Corporation as a director, officer, employee or agent of
another corporation, limited liability company, partnership, joint venture,
trust or other enterprise or employee benefit plan, against liability and
expenses (including court costs and attorney's fees), judgments, fines, excise
taxes and amounts paid in satisfaction, settlement or compromise actually and
reasonably incurred by such person in connection with such action, suit or
proceeding to the full extent authorized by Section 2-418 of the MGCL or any
successor provision thereto.

   C. Advancement of Expenses. Reasonable expenses incurred by a director,
officer, employee or agent of the Corporation in defending a civil or criminal
action, suit or proceeding described in Article VIII.B. shall be paid by the
Corporation in advance of the final disposition of such action, suit or
proceeding as authorized by the Board of Directors only upon receipt of written
affirmation by or on behalf of such person of his good faith belief that he has
met the standard of conduct necessary for indemnification under relevant law and
a written undertaking to repay such amount if it shall ultimately be determined
that the person has not met that standard.

   D. Other Rights and Remedies. The indemnification provided by this Article
VIII shall not be deemed to exclude any other rights to which those seeking
indemnification or advancement of expenses may be entitled under the
Corporation's Articles of Incorporation, 

                                     II-6
<PAGE>   109

any insurance or other agreement, trust fund, letter of credit, surety bond,
vote of stockholders or disinterested directors or otherwise, both as to actions
in their official capacity and as to actions in another capacity while holding
such office, and shall continue as to a person who has ceased to be a director,
officer, employee or agent and shall inure to the benefit of the heirs,
executors and administrators of such person; provided that no indemnification
shall be made to or on behalf of an individual if a judgment or other final
adjudication establishes that his actions, or omissions to act, were material to
the cause of action as adjudicated and (i) were committed in bad faith; or (ii)
were the result of active and deliberate dishonesty; or (iii) the director
actually received an improper personal benefit in money, property or services;
or (iv) in the case of any criminal proceedings, the director had reasonable
cause to believe that the act or omission was unlawful; provided, however, that
a director who has been successful, on the merits or otherwise, in the defense
of proceedings referred to under clauses (i) through (iv) above, may still be
indemnified as to reasonable expenses actually incurred by such person in
connection with the proceeding as approved by a disinterested majority of the
Board of Directors.

   E. Insurance. Upon resolution passed by the Board of Directors, the
Corporation may purchase and maintain insurance on behalf of any person who is
or was a director, officer, employee or agent of the Corporation, or was serving
at the request of the Corporation as a director, officer, employee or agent of
another corporation, limited liability company, partnership, joint venture,
trust or another enterprise or employee benefit plan, against any liability
asserted against him or incurred by him in any such capacity, or arising out of
his status, whether or not the Corporation would have the power to indemnify him
against such liability under the provisions of this Article or the MGCL.

   F. Modification. The duties of the Corporation to indemnify and to advance
expenses to a director, officer, employee or agent provided in this Article VIII
shall be in the nature of a contract between the Corporation and each such
director, officer, employee or agent and no amendment or repeal of any provision
of this Article VIII shall alter, to the detriment of such director, officer,
employee or agent, the right of such person to the advance of expenses or
indemnification related to a claim based on an act or failure to act which took
place prior to such amendment or repeal.

   G. Proceedings Initiated by Indemnified Persons. Notwithstanding any other
provision of this Article VIII, the Corporation shall not indemnify a director,
officer, employee or agent for any liability incurred in an action, suit or
proceeding initiated by (which shall not be deemed to include counter-claims or
affirmative defenses) or participated in as an intervenor or amicus curiae by
the person seeking indemnification unless such initiation of or participation in
the action, suit or proceeding is authorized, either before or after its
commencement, by the affirmative vote of a disinterested majority of the
directors then in office or unless intervention is required by law in order to
protect the rights, claims or defenses of the director, officer, employee or
agent with respect to matters for which the Corporation shall otherwise be
required to provide indemnification hereunder."

   Article X of the Company's Bylaws states:

   "(a) A director of the Corporation shall not be personally liable for
monetary damages for action taken, or any failure to take action, as a director,
to the extent set forth in the 

                                     II-7

Corporation's Articles of Incorporation, which provisions are incorporated
herein with the same affect as if they were set forth herein.

      (b) The Corporation shall indemnify any person who is a director, officer,
employee or agent of the Corporation to the extent set forth in the
Corporation's Articles of Incorporation, which provisions are incorporated
herein with the same affect as if they were set forth herein."

   In addition, the Company intends to obtain a directors and officers liability
insurance policy relating to certain actions or omissions which may be taken, or
omitted to be taken, by the directors and officers of the Company, as well as a
policy which insures against errors and omissions in the offering documents
relating to the offer and sale of the Common Stock to the public.

ITEM 26. RECENT SALES OF UNREGISTERED SECURITIES.

   On January 22, 1998, in connection with the Company's formation, ICARUS sold

ITEM 28.  UNDERTAKINGS

   The undersigned Registrant hereby provides the following undertakings:

   (a) The Registrant will provide to the Underwriter at the closing specified
in the Underwriting Agreement certificates in such denominations and registered
in such names as required by the Underwriter to permit prompt delivery to each
purchaser.

   (b) Insofar as indemnification for liabilities arising under the Securities
Act 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 Securities Act
and is, therefore, unenforceable.

   (c) For determining any liability under the Securities Act, treat the

prospectus filed by the Registrant under Rule 424(b)(1), or (4), or 497(h) under
the Securities Act as part of this Registration Statement as of the time the
Commission declared it effective.

post-effective amendment that contains a form of prospectus as a new

and that offering of the securities at that time as the initial bona fide
offering of those securities.

(a)(i) for U.S. federal income tax purposes, consummation of the

controlled by the transferors in exchange for stock as set forth in Section 351
of the Code; (ii) that no taxable gain will be recognized by any Party to the
Recapitalization upon the consummation of this Agreement; (iii) that the basis
of the Hold Co Common Stock and the Hold Co Preferred Stock received by Mr.

Stock surrendered by them therefore; (ii) that, if the Hold Co Common Stock and
Hold Co Preferred Stock is a capital asset in the hands of Mr. Blecker and Mrs.
Blecker at the effective time of the Recapitalization, then the holding period
of the Hold Co Common Stock and Hold Co Preferred Stock received by them in the
Recapitalization will include the holding period of the UK Stock and MD Stock
surrendered therefore; and, (b)(i) for UK income tax purposes, the transfer of
shares of UK Stock in exchange for Hold Co Preferred Stock will not constitute
a taxable disposal for UK tax purposes.  In rendering such opinion, Grant
Thornton LLP may rely upon representations contained in certificates of the
Parties.

                                    ARTICLE V

                                  CAPITAL STOCK

         Capital Stock. The total number of shares of capital stock which the
Corporation has authority to issue is 25,000,000, of which 20,000,000 shall be
common stock, $0.01 par value per share (hereinafter the "Common Stock") and of
which 5,000,000 shall be preferred stock, $0.01 par value per share (hereinafter
the "Preferred Stock"). The aggregate par value of all the shares of all classes
of the capital stock which the Corporation has the authority to issue is
$250,000.00. The Board of Directors shall have the authority to establish series
of unissued shares of any class of capital stock by fixing and determining the
number, designations, preferences, limitations and relative rights, including
voting rights, of the shares of any series so established to the same extent
that such number, designations, preferences, limitations and relative rights
could be stated if fully set forth in these Articles of Incorporation. Except to
the extent required by governing law, the shares of capital stock may be issued
from time to time by resolution of the Board of Directors without further
approval of stockholders. The Corporation shall have the authority to purchase
its capital stock out of funds lawfully available therefor, which capital stock,
unless otherwise stated herein or in any resolution relating to the Preferred
Stock, shall constitute authorized but unissued shares and may then be issued by
the Corporation as set forth herein.

         A description of the different classes and series (if any) of the
Corporation's capital stock and a statement of the designations, and the
relative rights, preferences and limitations of the shares of each class of and
series (if any) of capital stock are as follows:

         A. Common Stock. Except as provided in this Article V (or in any
resolution or resolutions adopted by the Board of Directors pursuant hereto),
the exclusive voting power shall be vested in the Common Stock, the holders
thereof being entitled to one vote for each share of such Common Stock standing
in the holder's name on the books of the Corporation. Subject to any rights and
preferences of any class of stock having preference over the Common Stock,
holders of Common Stock shall be entitled to such dividends as may be declared
by the Board of Directors out of funds lawfully available therefor. Upon any
liquidation, dissolution or winding up of the affairs of the Corporation,
whether voluntary or involuntary, holders of Common Stock shall be entitled to
receive pro rata the

ICARUS International, Inc.
Articles of Incorporation
Page 3

remaining assets of the Corporation after the payment or provision for payment
of the Corporation's debts and liabilities and after the holders of any class of
stock having preference over the Common Stock have been paid in full any sums to
which they may be entitled.

         B.       Preferred Stock, Series A.

                  (a) Designation and Rank. The designation of the series of
preferred stock authorized by these Articles of Incorporation shall be Preferred
Stock, Series A (the "Series A Preferred Stock"). The Series A Preferred Stock
shall be perpetual unless redeemed at the option of the Corporation pursuant to
Article V.B.(c) hereof. The Series A Preferred Stock shall consist of one
hundred (100) shares, all of which shall be issuable solely in whole shares. The
Series A Preferred Stock shall be junior to all outstanding indebtedness of the
Corporation. The Series A Preferred Stock shall rank prior to the Corporation's
Common Stock, and to all other classes and series of equity securities of the
Corporation now or hereafter authorized, issued or outstanding (the Common Stock
and such other classes and series of equity securities collectively may be
referred to herein as the "Junior Stock"), other than any classes or series of
equity securities of the Corporation expressly designated as ranking on a parity
with (the "Parity Stock") or senior to (the "Senior Stock") the Series A
Preferred Stock as to, among other things, dividend rights and/or rights upon
liquidation, winding up or dissolution of the Corporation. The Series A
Preferred Stock shall be subject to creation of Senior Stock, Parity Stock and
Junior Stock to the extent not expressly prohibited by these Articles of
Incorporation or otherwise, and shall be initially issued upon terms determined
by the Board of Directors of the Corporation.

                  (b) Dividends. Holders of shares of Series A Preferred Stock
shall not be entitled to receive dividends in any form, including, but not
limited to, cash, Common Stock or other payment-in-kind.

                  (c) Redemption. The shares of the Series A Preferred Stock are
non-redeemable.

                  (d) Voting Rights. The Series A Preferred Stock shall have no
voting rights.

                  (e) No Sinking Fund. No sinking fund will be established for
the retirement or redemption of shares of Series A Preferred Stock.

                  (f) Registration Rights. The holders of the Series A Preferred
Stock have no right to request that the Series A Preferred Stock be registered
for sale under the Securities Act of 1933, as amended, or any state securities
act.

                  (g)     Liquidation Preference.

                          (i)    Amount and Type of Liquidation Preference.  
In the event of any liquidation, dissolution or winding up of the affairs of the
Corporation, whether voluntary or involuntary, after payment or provision for
payment of the debts and other liabilities of the Corporation, the holders of
shares of Series A Preferred Stock shall be entitled to receive, out of the
assets of the Corporation available for distribution to stockholders, an amount
in cash equal to $1,000.00 for each share outstanding (the "Liquidation
Preference"). If upon such voluntary or involuntary dissolution, liquidation or
winding up of the affairs of the Corporation, the net assets of the Corporation
shall be insufficient to permit payment in full of the amounts required to be
paid to the holders of the Series A Preferred Stock and to the holders of any
class of stock or series thereof ranking on a parity with the Series A Preferred
Stock in respect of the distribution of assets, then a pro rata portion of the
full amount required to be paid upon such dissolution, liquidation or winding up
shall be paid to (A) the holders of Series A Preferred Stock and (B) the holders
of any class of stock or series thereof ranking on a parity with the Series A
Preferred Stock in respect of the distribution of assets in proportion to the
respective preferential amounts to which they are entitled (but only to the
extent of such preferential amounts). Such pro rata portion shall be calculated
upon the ratio that the total amount available for distribution to such holders
bears to the total distribution required to be made on the Series A Preferred
Stock and such Parity Stock. After payment of the full amount of the liquidating
distribution to which they are entitled, the holders of the Series A Preferred
Stock will not be entitled to any further participation in any distribution of
assets of the Corporation.

                          (ii)   No Dissolution.  Neither a change in control, 
merger nor consolidation of the Corporation into or with any other company, nor
the merger or consolidation of any other company into or with the Corporation,
nor a sale, transfer or lease of all or any part of the assets of the
Corporation, shall be deemed to be a liquidation, dissolution or winding up of
the Corporation within the meaning of this Article V.B.(g).

                          (iii)  Notice of Liquidation. Written notice of any
voluntary or involuntary liquidation, dissolution or winding up of the affairs
of the Corporation, stating a payment date and the place where the distributable
amounts shall be payable, shall be given as set forth in Article V.B.(i) hereof,
no less than thirty (30) days prior to the payment date stated therein, to the
holders of record of the Series A Preferred Stock at their respective addresses
as the same shall appear on the stock register of the Corporation.

                  (h)     No Other Rights. The shares of Series A Preferred 
Stock are not entitled to any preferences, powers or rights (including but not
limited to, preemptive rights to acquire any equity or debt securities of the
Corporation) except as set forth in these Articles of Incorporation. The Board
of Directors shall have the full authority to interpret and construe the terms
and conditions and rights, privileges and limitations set forth herein and 


<PAGE>   5
ICARUS International, Inc.
Articles of Incorporation
Page 5

any such written interpretation or construction by the Board shall be final and
binding upon the holders of the Series A Preferred Stock.

                  (i) Notices. Any notice required by the provisions of this
Article V.B. to be given to the holders of shares of Series A Preferred Stock
shall be deemed given if deposited in the United States mail, postage prepaid,
and addressed to each holder of record at his or her address appearing on the
books of the Corporation.

                  (j) Severability of Provisions. Whenever possible, each
provision hereof shall be interpreted in a manner as to be effective and valid
under applicable law, but if any provision hereof is held to be prohibited by or
invalid under applicable law, such provision shall be ineffective only to the
extent of such prohibition or invalidity, without invalidating or otherwise
adversely affecting the remaining provisions hereof. If a court of competent
jurisdiction should determine that a provision hereof would be valid or
enforceable if a period of time were extended or shortened or a particular
percentage were increased or decreased, then such court may make such change as
shall be necessary to render the provision in question effective and valid under
applicable law.

         C.       Preferred Stock. The Board of Directors is hereby expressly
authorized to provide, by resolution or resolutions, out of the unissued shares
of Preferred Stock, for additional series of Preferred Stock. Before any shares
of any such series are issued, the Board of Directors shall fix, and hereby is
expressly empowered to fix, by resolution or resolutions, the following
provisions of the shares thereof:

                  (a) The designation of such series, the number of shares to 
constitute such series and the stated value thereof;

                  (b) Whether the shares of such series shall have voting
rights, in addition to any voting rights provided by law, and, if so, the terms
of such voting rights, which may be general or limited;

                  (c) The dividends, if any, payable on such series, whether any
such dividends shall be cumulative, and, if so, from what dates, the conditions
and dates upon which such dividends shall be payable, the preference or relation
which such dividends shall bear to the dividends payable on any shares of stock
of any other class or any other series of this class;

                  (d) Whether the shares of such series shall be subject to
redemption by the Corporation, and, if so, the times, prices and other
conditions of such redemption;

                  (e) The amount or amounts payable upon shares of such series
upon, and the rights of the holders of such series in, the voluntary or
involuntary liquidation, dissolution or winding up, or upon any distribution of
the assets, of the Corporation;


<PAGE>   6
ICARUS International, Inc.
Articles of Incorporation
Page 6


                  (f) Whether the shares of such series shall be subject to the
operation of a retirement or sinking fund and, if so, the extent to and manner
in which any such retirement or sinking fund shall be applied to the purchase or
redemption of the shares of such series for retirement or other corporate
purposes and the terms and provisions relative to the operation thereof;

                  (g) Whether the shares of such series shall be convertible
into, or exchangeable for, shares of stock of any other class or any other
series of this class or any other securities, and, if so, the price or prices or
the rate or rates of conversion or exchange and the method, if any, of adjusting
the same, and any other terms and conditions of conversion or exchange;

                  (h) The price or other consideration for which the shares of
such series shall be issued;

                  (i) Whether the shares of such series which are redeemed or
converted shall have the status of authorized but unissued shares of Preferred
Stock and whether such shares may be reissued as shares of the same or any other
series of Preferred Stock;

                  (j) The limitations and restrictions, if any, to be effective
while any shares of such series are outstanding upon the payment of dividends or
the making of other distributions on, and upon the purchase, redemption or other
acquisition by the Corporation of, the Common Stock or shares of stock of any
other class or any other series of this class;

                  (k) The conditions or restrictions, if any, upon the creation
of indebtedness of the Corporation or upon the issue of any additional stock,
including additional shares of such series or of any other series of this class
or of any other class; and

                  (l) Any other powers, preferences and relative, participating,
optional and other special rights, and any qualifications, limitations and
restrictions thereof.

         The powers, preferences and relative, participating, optional and other
special rights of each series of Preferred Stock, and the qualifications,
limitations or restrictions thereof, if any, may differ from those of any and
all other series, except that shares of any one series issued at different times
may differ as to the dates from which dividends thereon shall accrue and/or be
cumulative.

         Prior to the issuance of any shares of a series of capital stock
established by resolution adopted by the Board of Directors, if such issuance is
the first issuance of shares of such series since the resolution was adopted,
the Corporation shall file with the Department for record articles supplementary
as required by the MGCL. Upon the filing of such articles supplementary with the
Department, the resolution establishing and designating the series

and fixing and determining the preferences, limitations and relative rights
thereof shall become an amendment of these Articles of Incorporation.

                                   ARTICLE VI

                              NO PREEMPTIVE RIGHTS

         No Preemptive Rights. No holder of the capital stock of the Corporation
shall be entitled as such, as a matter of right or otherwise, to subscribe for
or purchase any part of any new or additional issue of equity or debt of any
class or series whatsoever, of the Corporation, or of securities convertible
into equity or debt of any class whatsoever, whether now or hereafter
authorized, or whether issued for cash or other consideration or by way of a
dividend.

                                   ARTICLE VII

                               BOARD OF DIRECTORS

         Directors. The business and affairs of the Corporation shall be managed
by or under the direction of a Board of Directors. The current number of
directors of the Corporation is three (3). The names of the current members of
the Board of Directors of the Corporation are: Herbert G. Blecker, Eunice E.
Blecker and William F. Geritz III. The business address of each member of the
Board of Directors of the Corporation is One Central Plaza, 11300 Rockville
Pike, Rockville, Maryland 20852.

         Except as otherwise fixed pursuant to the provisions of Article V
hereof relating to the rights of the holders of any class or series of stock
having a preference over the Common Stock as to dividends or upon liquidation to
elect additional directors, the number of directors shall be determined by
resolution of the majority of the entire Board of Directors as provided in the
Corporation's Bylaws, as may be amended from time to time, provided, however,
that the number of directors shall not be less than three nor greater than
twenty-one. Directors shall be elected by a plurality of the votes cast by the
holders of shares entitled to vote in the election of directors at a meeting of
stockholders at which a quorum is present.

         A. Classification and Term. The Board of Directors, other than those
who may be elected by the holders of any class or series of stock having
preference over the Common Stock as to dividends or upon liquidation, shall be
divided into three classes as nearly equal in number as possible, with one class
to be elected annually, as set forth in the Bylaws of the Corporation. The terms
of the initial directors shall expire as of the day of the annual meeting of
stockholders in the calendar year specified provided their respective successor
shall be duly elected and qualified in accordance with the provisions of these
Articles of

Incorporation and the Bylaws of the Corporation: Mrs. Blecker in 1998, Mr.
Geritz in 1999 and Mr. Blecker in 2000.

         B. Vacancies. Except as otherwise fixed pursuant to the provisions of
Article V hereof relating to the rights of the holders of any class or series of
stock having a preference over the Common Stock as to dividends or upon
liquidation to elect directors, any vacancy occurring in the Board of Directors,
whether due to an increase in the number of directors or otherwise, shall be
filled by a majority vote of the Whole Board of Directors and a majority of the
Continuing Directors then in office (as each term is defined by Article X)
though less than a quorum of the Board of Directors, or by a sole remaining
director, and any director so chosen shall be elected until the next annual
meeting of stockholders and until such director's successor shall have been
elected and qualified. Whenever the holders of any class or series of shares or
group of classes or series of shares are entitled to elect one or more directors
by the provisions of these Articles of Incorporation, any vacancies in such
directorships and any newly created directorships of such class or series to be
filled by reason of increase in the number of such directors shall be filled by
the affirmative vote of a majority vote of the Whole Board of Directors and a
majority of the Continuing Directors then in office, though less than a quorum
of the Board of Directors, or by a sole remaining director, and any director so
chosen shall be elected until the next annual meeting of stockholders and until
such director's successor shall have been elected and qualified. When the number
of directors is changed, the Board of Directors shall determine the class or
classes to which the increased or decreased number of directors shall be
apportioned; provided that no decrease in the number of directors shall shorten
the term of any incumbent director.

         C. Removal. Subject to the rights of any class or series of stock
having preference over the Common Stock as to dividends or upon liquidation to
elect directors, any director (including persons elected by directors to fill
vacancies in the Board of Directors) may be removed from office with or without
cause by an affirmative vote of not less than two-thirds of the votes eligible
to be cast by stockholders at a duly constituted meeting of stockholders called

capital stock of the Corporation are entitled to elect one or more directors by
the provisions of these Articles of Incorporation or any amendment or supplement
thereto, only the holders of shares of that class or series of capital stock
shall be entitled to vote for or against the removal of any director elected by
the holders of the shares of that class or series. At least thirty (30) days
prior to such meeting of stockholders, written notice shall be sent to the
director whose removal will be considered at the meeting.

         D. Nominations of Directors. Nominations of candidates for election as
directors of the Corporation at any annual meeting of stockholders may be made

forth in this Article VII.D. shall be eligible for election as directors at an
annual meeting of stockholders. Ballots bearing the names of all the persons who
have been nominated for election as directors at an annual meeting in accordance
with the procedures set forth in this Article VII.D. shall be provided for use
at the annual meeting of stockholders.

         Subject to the rights of the holders of any class or series of stock
having a preference over the Common Stock as to dividends or upon liquidation,
nominations, other than those made by or at the direction of the Board of
Directors, shall be made pursuant to timely notice in writing to the Secretary
of the Corporation as set forth in this Article VII.D. To be timely, a
stockholder's notice shall be delivered to, or mailed and received at, the
principal office of the Corporation not less than (i) with respect to an
election to be held at any annual meeting of stockholders of the Corporation,
(a) for the first such annual meeting after the filing of these Articles of
Incorporation, before the close of business on the tenth day following the date
on which notice of such meeting is first given to stockholders, and (b)
thereafter, sixty (60) days prior to the anniversary date of the mailing of
proxy materials by the Corporation in connection with the immediately preceding
annual meeting of stockholders of the Corporation; and (ii) with respect to a
special meeting of stockholders for the election of directors, the close of
business on the tenth day following the date on which notice of such meeting is
first given to stockholders. Such stockholder's notice shall set forth (a) as to
each person whom the stockholder proposes to nominate for election or
re-election as a director and as to the stockholder giving the notice (i) the
name, age, business address and residence address of such person, (ii) the
principal occupation or employment of such person, (iii) the class and number of
shares of Corporation stock which are beneficially owned by such person on the
date of such stockholder notice, and (iv) any other information relating to such
person that is required to be disclosed in solicitations of proxies with respect
to nominees for election as directors pursuant to Regulation 14A under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), including, but
not limited to, information required to be disclosed by Items 4, 5, 6 and 7 of
Schedule 14A (or any successors of such items); and (b) as to the stockholder
giving the notice (i) the name and address, as they appear on the Corporation's
books, of such stockholder and any other stockholders known by such stockholder
to be supporting such nominees and (ii) the class and number of shares of
Corporation stock which are beneficially owned by such stockholder on the date
of such stockholder notice and, to the extent known, by any other stockholders
known by such stockholder to be supporting such nominees on the date of such
stockholder notice. At the request of the Board of Directors, any person
nominated by, or at the direction of, the Board for election as a director at an
annual or special meeting of stockholders shall furnish to the Secretary of the
Corporation that information required to be set forth in a stockholder's notice
of nomination which pertains to the nominee.

         The Board of Directors may reject any nomination by a stockholder not
timely made in accordance with the requirements of this Article VII.D. If the
Board of Directors, or a designated committee thereof, determines that the
information provided in a stockholder's 


<PAGE>   10
ICARUS International, Inc.
Articles of Incorporation
Page 10


notice does not satisfy the informational requirements of this Article VII.D. in
any material respect, the Secretary of the Corporation shall promptly notify
such stockholder of the deficiency in the notice. The stockholder shall have an
opportunity to cure the deficiency by providing additional information to the
Secretary within such period of time, not to exceed five (5) days from the date
such deficiency notice is given to the stockholder, as the Board of Directors or
such committee thereof shall reasonably determine. If the deficiency is not
cured within such period, or if the Board of Directors or such committee thereof
reasonably determines that the additional information provided by the
stockholder, together with information previously provided, does not satisfy the
requirements of this Article VII.D. in any material respect, then the Board of
Directors may reject such stockholder's nomination. The Secretary of the
Corporation shall notify a stockholder in writing whether his nomination has
been made in accordance with the time and informational requirements of this
Article VII.D. Notwithstanding the procedures set forth in this paragraph, if
neither the Board of Directors nor such committee thereof makes a determination
as to the validity of any nominations by a stockholder, the presiding officer of
the annual meeting of stockholders shall determine and declare at the annual
meeting whether the nomination was made in accordance with the terms of this
Article VII.D. If the presiding officer determines that a nomination was made in
accordance with the terms of this Article VII.D., he shall so declare at the
annual meeting of stockholders and ballots shall be provided for use at the
meeting with respect to such nominee. If the presiding officer determines that a
nomination was not made in accordance with the terms of this Article VII.D., he
shall so declare at the annual meeting and the defective nomination shall be
disregarded.

         Notwithstanding the foregoing, and except as otherwise required by law,
whenever the holders of any one or more series of Preferred Stock shall have the
right, voting separately as a class, to elect one or more directors of the
Corporation, the provisions of this Article VII.D. shall not apply with respect
to the director or directors elected by such holders of Preferred Stock.

         E. Discharge of Duties. In discharging the duties of their respective
positions, the Board of Directors, committees of the Board and individual
directors shall, in considering the best interests of the Corporation, consider
the effects of any action upon the employees of the Corporation, its customers,
the communities in which offices or other establishments of the Corporation or
any subsidiary are located and all other pertinent factors.

                                  ARTICLE VIII

           INDEMNIFICATION, ETC. OF OFFICERS, DIRECTORS, EMPLOYEES AND
                                     AGENTS

         A. Limitation of Liability. No director who has performed his or her
duties in accordance with the standard set forth in Section 2-405.1 of the MGCL
(or any successor provision thereto) shall be personally liable to the
Corporation or its stockholders for monetary damages for any act or omission by
such director as a director; provided that a director's liability shall not be
limited or eliminated to the extent that: (i) it is proved that the director
actually received an improper benefit or profit in money, property or services
for the amount of the benefit or profit in money, property or services actually
received; or (ii) a judgment or other final adjudication adverse to the director
is entered in a proceeding based on a finding in the proceeding that the
director's action, or failure to act, was the result of active and deliberate
dishonesty and was material to the cause of action adjudicated in the
proceeding. No amendment to or repeal of this Article VIII.A. shall apply to or
have any effect on the liability or alleged liability of any director of the
Corporation for or with respect to any acts or omissions of such director
occurring prior to such amendment.

         B. Indemnification. The Corporation shall indemnify any person who was
or is a party or is threatened to be a made a party to any threatened, pending
or completed action, suit or proceeding, whether civil, criminal,
administrative, arbitrative or investigative, by reason of the fact that such
person is or was a director, officer, employee or agent of the Corporation, or
is or was serving at the request of the Corporation as a director, officer,
employee or agent of another corporation, limited liability company,
partnership, joint venture, trust or other enterprise or employee benefit plan,
against liability and expenses (including court costs and attorney's fees),
judgments, fines, excise taxes and amounts paid in satisfaction, settlement or
compromise actually and reasonably incurred by such person in connection with
such action, suit or proceeding to the full extent authorized by Section 2-418
of the MGCL or any successor provision thereto.

         C. Advancement of Expenses. Reasonable expenses incurred by a director,
officer, employee or agent of the Corporation in defending a civil or criminal
action, suit or proceeding described in Article VIII.B. shall be paid by the
Corporation in advance of the final disposition of such action, suit or
proceeding as authorized by the Board of Directors only upon receipt of written
affirmation by or on behalf of such person of his good faith belief that he has
met the standard of conduct necessary for indemnification under relevant law and
a written undertaking to repay such amount if it shall ultimately be determined
that the person has not met that standard.

         D. Other Rights and Remedies. The indemnification provided by this
Article VIII shall not be deemed to exclude any other rights to which those
seeking indemnification or advancement of expenses may be entitled under the
Corporation's Articles of Incorporation, any insurance or other agreement, trust
fund, letter of credit, surety bond, vote of stockholders or disinterested
directors or otherwise, both as to actions in their official capacity and as to
actions in another capacity while holding such office, and shall continue as to
a person who has ceased to be a director, officer, employee or agent and shall
inure to the benefit of the heirs, executors and administrators of such person;
provided that no indemnification shall be made to or on behalf of an individual
if a judgment or other final adjudication establishes that his actions, or
omissions to act, were material to the cause of action as adjudicated and (i)
were committed in bad faith; or (ii) were the result of active and deliberate
dishonesty; or (iii) the director actually received an improper personal benefit
in money, property or services; or (iv) in the case of any criminal proceedings,
the director had reasonable cause to believe that the act or omission was
unlawful; provided, however, that a director who has been successful, on the
merits or otherwise, in the defense of proceedings referred to under clauses (i)
through (iv) above, may still be indemnified as to reasonable expenses actually
incurred by such person in connection with the proceeding as approved by a
disinterested majority of the Board of Directors.

         E. Insurance. Upon resolution passed by the Board of Directors, the
Corporation may purchase and maintain insurance on behalf of any person who is
or was a director, officer, employee or agent of the Corporation, or was serving
at the request of the Corporation as a director, officer, employee or agent of
another corporation, limited liability company, partnership, joint venture,
trust or another enterprise or employee benefit plan, against any liability
asserted against him or incurred by him in any such capacity, or arising out of
his status, whether or not the Corporation would have the power to indemnify him
against such liability under the provisions of this Article or the MGCL.

         F. Modification. The duties of the Corporation to indemnify and to
advance expenses to a director, officer, employee or agent provided in this
Article VIII shall be in the nature of a contract between the Corporation and
each such director, officer, employee or agent and no amendment or repeal of any
provision of this Article VIII shall alter, to the detriment of such director,
officer, employee or agent, the right of such person to the advance of expenses
or indemnification related to a claim based on an act or failure to act which
took place prior to such amendment or repeal.

         G. Proceedings Initiated by Indemnified Persons. Notwithstanding any
other provision of this Article VIII, the Corporation shall not indemnify a
director, officer, employee or agent for any liability incurred in an action,
suit or proceeding initiated by (which shall not be deemed to include
counter-claims or affirmative defenses) or participated in as an intervenor or
amicus curiae by the person seeking indemnification unless such initiation of or
participation in the action, suit or proceeding is authorized, either before or
after its 


<PAGE>   13

Articles of Incorporation
Page 13


commencement, by the affirmative vote of a disinterested majority of the
directors then in office or unless intervention is required by law in order to
protect the rights, claims or defenses of the director, officer, employee or
agent with respect to matters for which the Corporation shall otherwise be
required to provide indemnification hereunder.

                                   ARTICLE IX

               MEETINGS OF STOCKHOLDERS AND STOCKHOLDER PROPOSALS

         A. Special Meetings of Stockholders. Except as otherwise required by
law and subject to the rights of the holders of any class or series of Preferred
Stock, special meetings of the stockholders of the Corporation may be called
only by (i) the Board of Directors pursuant to a resolution approved by the
affirmative vote of a majority of the Whole Board of Directors and a majority of
the Continuing Directors then in office, (ii) the Chairman of the Board, (iii)
the President, or (iv) the holders of not less than a majority of all votes
entitled to be cast on any issue proposed to be considered at such special
meeting. A request for a special meeting of stockholders by stockholders of the
Corporation shall state the purpose of the meeting and the matters proposed to
be acted on. The Secretary of the Corporation shall inform the stockholders who
make the request for the special meeting of the reasonably estimated cost of
preparing and mailing a notice of the meeting and on payment of such costs to
the Corporation, the Secretary shall notify each stockholder entitled to notice
of the special meeting.

         B. Action Without a Meeting. Any action permitted to be taken by the
stockholders at a meeting may be taken without a meeting if consent in writing
setting forth the action so taken shall be signed by all of the stockholders who
would be entitled to vote at a meeting for such purpose and a written waiver of
any right to dissent signed by each stockholder entitled to notice of the
meeting but not entitled to vote at it, and both are filed with the Secretary of
the Corporation as part of the corporate records.

         C. Stockholder Proposals. At an annual meeting of stockholders, only
such business shall be conducted, and only such proposals shall be acted upon,
as shall have been brought before the annual meeting by, or at the direction of,
(a) the Board of Directors or (b) any stockholder of the Corporation who
complies with all the requirements set forth in this Article IX.C.

         Proposals, other than those made by or at the direction of the Board of
Directors, shall be made pursuant to timely notice in writing to the Secretary
of the Corporation as set forth in this Article IX.C. For stockholder proposals
to be included in the Corporation's proxy materials, the stockholder must comply
with all the timing and informational requirements of Rule 14a-8 of the Exchange
Act (or any successor regulation). With respect to stockholder proposals to be
considered at the annual meeting of stockholders but not 


<PAGE>   14
ICARUS International, Inc.
Articles of Incorporation
Page 14

included in the Corporation's proxy materials, the stockholder's notice shall be
delivered to, or mailed and received at, the principal office of the Corporation
(a) for the first such annual meeting after the filing of these Articles of
Incorporation, before the close of business on the tenth day following the date
on which notice of such meeting is first given to stockholders, and (b)
thereafter, not less than sixty (60) days prior to the anniversary date of the
mailing of proxy materials by the Corporation in connection with the immediately
preceding annual meeting of stockholders of the Corporation. Such stockholder's
notice shall set forth as to each matter the stockholder proposes to bring
before the annual meeting (a) a brief description of the proposal desired to be
brought before the annual meeting and the reasons for conducting such business
at the annual meeting, (b) the name and address, as they appear on the
Corporation's books, of the stockholder proposing such business and, to the
extent known, any other stockholders known by such stockholder to be supporting
such proposal, (c) the class and number of shares of the Corporation stock which
are beneficially owned by the stockholder on the date of such stockholder notice
and, to the extent known, by any other stockholders known by such stockholder to
be supporting such proposal on the date of such stockholder notice, and (d) any
financial interest of the stockholder in such proposal (other than interests
which all stockholders would have).

         The Board of Directors may reject any stockholder proposal not timely
made in accordance with the terms of this Article IX.C. If the Board of
Directors, or a designated committee thereof, determines that the information
provided in a stockholder's notice does not satisfy the informational
requirements of this Article IX.C. in any material respect, the Secretary of the
Corporation shall promptly notify such stockholder of the deficiency in the
notice. The stockholder shall have an opportunity to cure the deficiency by
providing additional information to the Secretary within such period of time,
not to exceed five (5) days from the date such deficiency notice is given to the
stockholder, as the Board of Directors or such committee thereof shall
reasonably determine. If the deficiency is not cured within such period, or if
the Board of Directors or such committee thereof determines that the additional
information provided by the stockholder, together with information previously
provided, does not satisfy the requirements of this Article IX.C. in any
material respect, then the Board of Directors may reject such stockholder's
proposal. The Secretary of the Corporation shall notify a stockholder in writing
whether his proposal has been made in accordance with the time and informational
requirements of this Article IX.C. Notwithstanding the procedures set forth in
this paragraph, if neither the Board of Directors nor such committee thereof
makes a determination as to the validity of any stockholder proposal, the
presiding officer of the annual meeting shall determine and declare at the
annual meeting whether the stockholder proposal was made in accordance with the
terms of this Article IX.C. If the presiding officer determines that a
stockholder proposal was made in accordance with the terms of this Article
IX.C., he shall so declare at the annual meeting and ballots shall be provided
for use at the meeting with respect to any such proposal. If the presiding
officer determines that a stockholder proposal was not made in 


<PAGE>   15
ICARUS International, Inc.
Articles of Incorporation
Page 15


accordance with the terms of this Article IX.C., he shall so declare at the
annual meeting and any such proposal shall not be acted upon at the annual
meeting.

         This provision shall not prevent the consideration and approval or
disapproval at the annual meeting of reports of officers, directors and
committees of the Board of Directors, but in connection with such reports, no
new business shall be acted upon at such annual meeting unless stated, filed and
received as herein provided.

                      advisability (or inadvisability) of the Business
                      Combination which the Continuing Directors, or any of

                      advisable by a majority of the Continuing Directors, an
                      opinion of a reputable investment banking firm as to the
                      fairness (or lack of fairness) of the terms of such
                      Business Combination from the point of view of the holders
                      of Voting Shares other than any Related Person (such
                      investment banking firm to be selected by a majority of
                      the Continuing Directors, to be furnished with all
                      information it reasonably requests, and to be paid a
                      reasonable fee for its services upon receipt by the
                      Corporation of such opinion).

hereof, in the event of a Business Combination upon consummation of which the

exist (unless it is provided, contemplated or intended that as part of such
Business Combination or within one year after consummation thereof a plan of
liquidation or dissolution of the Corporation will be effected), the term "other
consideration to be received" shall include (without limitation)

Common Stock retained by the stockholders of the Corporation other than Related
Persons who are parties to such Business Combination.

Directors and a majority of the Continuing Directors after such acquisition.

           C.         Evaluation of Business Combinations, Etc. In connection 
with the exercise of its judgment in determining what is in the best interest of
the Corporation and its stockholders when evaluating a Business Combination or a
proposal by another Person or Persons to make a Business Combination or a tender
or exchange offer, the Board of Directors of the Corporation shall, in addition
to considering the adequacy of the amount to be paid in connection with any such
transaction, consider all of the following factors and any other factors which
it deems relevant: (i) the social and economic effects of the transaction on the
Corporation and its Subsidiaries and their respective employees, customers,
creditors and other elements of the communities in which the Corporation and its
Subsidiaries operate or are located; (ii) the business and financial condition
and earnings prospects of the acquiring Person or Persons, including, but not

the acquiring Person or Persons, and the possible effect of such conditions upon
the Corporation and its Subsidiaries and the elements of the communities in
which the Corporation and its Subsidiaries operate or are located; and (iii) the
competence, experience and integrity of the acquiring Person or Persons and its
or their management.

           D.         Voting Rights of Certain Control Shares. The Corporation 
shall be governed by the MGCL, Corporations and Associations Volume, Title 3
"Corporations in General Extraordinary Actions," Subtitle 7 "Voting Rights of
Certain Control Shares" and hereby adopts such language and provisions and
incorporates the same herein by reference as though it were written out herein
in full. The Corporation may redeem its shares as set forth in MGCL Section
3-707. If voting rights for "control shares" (as defined by MGCL Section
3-701(d)) are approved at a meeting held under MGCL Section 3-704 and the
"acquiring person" (as defined by MGCL Section 3-701(b)) is entitled to exercise
or direct the exercise of a majority or more of all voting power, all
stockholders of the Corporation, other than the acquiring person, shall have the
rights of objecting stockholders as set forth in MGCL Section 3-708.

           Anything in the preceding paragraph to the contrary notwithstanding,
the restrictions set forth in Title 3, Subtitle 7, Section 3-701, et seq. of the

           E.         Amendments, Etc. of this Article X. Notwithstanding any 
other provisions of these Articles of Incorporation or the Bylaws of the
Corporation (and notwithstanding the fact that some lesser percentage may be
specified by law, these Articles of Incorporation or the Bylaws of the
Corporation), this Article X shall not be amended, altered, changed, or
repealed without the affirmative vote of (i) the holders of 80% or more of the
outstanding Voting Shares, voting separately as a class, and (ii) an
Independent Majority of Stockholders; provided, however, that this Article X.E.
shall not apply to, and such vote shall not be required for, any such
amendment, change or repeal recommended to stockholders by the favorable vote
of not less than two-thirds of the Whole Board of Directors, including a
majority of the Continuing Directors, and any such amendment, change or repeal
so recommended shall require only the vote, if any, required under the
applicable provisions of the MGCL, these Articles of Incorporation and the
Bylaws of the Corporation.

           F.         Election Under Section 3-603 of the MGCL. The Corporation
has expressly elected, under Section 3-603(e)(iii) of the MGCL, not to be 
governed by the provisions of Title 3, Subtitle 6, Section 3-601, et seq. of 
the MGCL.

XI, and (ii) Article X shall be amended in the manner specified in Article X.E.

expressly set forth herein.

           2.5       Notice.

                     (a)       Notice of the time and place of the annual
meeting of stockholders shall be given by delivering personally, leaving at his
or her residence or usual place of business or by mailing to the stockholder's
address as it appears on the records of the Corporation, a written or printed
notice of the same stating the place, day and hour of the meeting, at least ten
(10) days and not more than ninety (90) days prior to the meeting, to each
stockholder of record entitled to vote at such meeting and to each other
stockholder entitled to notice of said meeting.

                     (b)       At least ten (10) days and not more than ninety
(90) days prior to the meeting, a written or printed notice of each special
meeting of stockholders, stating the place, day and hour of such meeting, and
the purpose or purposes for which the meeting is called, shall be either
delivered personally, left at his or her residence or principal place of
business or mailed to each stockholder of record entitled to vote at such
meeting at such stockholder's address as it appears on the records of the
Corporation and to each other stockholder entitled to notice of said meeting.

                     (c)       A person entitled to notice of any meeting of
stockholders may waive such notice if he or she: (i) before or after the meeting
signs a waiver of notice which is filed with the records of the stockholders'
meeting, or (ii) is present at the meeting in person or by proxy.

                     (d)       A meeting of stockholders, either annual or
special, convened on the date for which it was called may be adjourned from time
to time without further notice to a date not more than one hundred and twenty
(120) days after the original record date, unless a new record date is fixed and
if so fixed, the meeting may be adjourned to any date as may be determined by
the Board of Directors in their sole discretion. When any stockholders' meeting,
either annual or special, is adjourned and if a new record date is fixed for an
adjourned meeting of stockholders, notice of the adjourned meeting shall be
given as in the case of an original meeting. It shall not be necessary to give
any written 


<PAGE>   3
ICARUS International, Inc.
Bylaws
Page 3


notice of the time and place of any meeting adjourned, unless a new record date
is fixed therefor, other than an announcement at the meeting at which such
adjournment is taken.

           2.6      Voting List. At least ten (10) days before each meeting of
stockholders, a complete list of the stockholders entitled to vote at such
meeting, or any adjournment thereof, shall be made by the Secretary, arranged in
alphabetical order, with the address of and number of shares registered in the
name of each, which list shall be kept on file for the examination of any
stockholder, for any purpose germane to the meeting, during ordinary business
hours, at the principal office of the Corporation for a period of ten (10) days
prior to such meeting. The list shall be produced and kept open at the time and
place of such meeting by the Secretary of the Corporation and subject to the
inspection of any stockholder who may be present at the meeting. The Stock
Ledger shall be the only evidence as to who are the stockholders entitled to
examine the Stock Ledger, the voting list required by these Bylaws or the books
of the Corporation, or to vote in person or by proxy at any meeting of the
stockholders.

           2.7       Quorum; Voting.  Except as otherwise required by law:

                     (a)  A quorum for the transaction of business at any
annual or special meeting of stockholders shall consist of stockholders
representing, either in person or by proxy, a majority of the outstanding
capital stock of the Corporation entitled to vote on that matter at such
meeting, except as otherwise provided by statute, the Articles of Incorporation
or these Bylaws; but in the absence of such a quorum, the holders of a majority
of the shares represented at the meeting shall have the right successively to
adjourn the meeting to a specified date (the later scheduled meeting hereafter
referred to as the "adjourned meeting"). At the adjourned meeting, the
Corporation may transact any business which might have been transacted at the
original meeting. If a quorum shall be present at the commencement of a meeting
but shall withdraw leaving less than a quorum, the meeting may continue and the
Corporation may transact any business that might have been transacted had the
quorum remained. The absence from any meeting of the number of shares required
by law, the Articles of Incorporation or these Bylaws for action upon one matter
shall not prevent action at such meeting upon any other matter or matters which
may properly come before the meeting, if the number of shares required in
respect of such other matters shall be present.

                     (b)  With respect to any other matter other than the
election of directors, the votes of a majority of all votes cast at any properly
called meeting or adjourned meeting of stockholders at which a quorum, as
defined above, is present, shall be sufficient to approve any matter which
properly comes before the meeting, unless the proposition or question is one
upon which by express provisions of law or of the Articles of Incorporation or
these Bylaws, a different vote is required, in which case with express provision
shall govern and establish the number of votes required to determine such
proposition or question.


<PAGE>   4
ICARUS International, Inc.
Bylaws
Page 4



                     (c)  Directors are to be elected by a plurality of
votes cast by the shares entitled to vote in the election at a meeting at which
a quorum is present. Stockholders shall not be permitted to cumulate their votes
for the election of directors. If, at any meeting of the stockholders, due to a
vacancy or vacancies or otherwise, directors of more than one class of the Board
of Directors are to be elected, each class of directors to be elected at the
meeting shall be elected in a separate election by a plurality vote.

           2.8       Voting of Shares. Except as otherwise provided in these 
Bylaws or to the extent that voting rights of the shares of any class or classes
are limited or denied by the Articles of Incorporation, each stockholder, on
each matter submitted to a vote at a meeting of stockholders, shall have one (1)
vote for each share of stock registered in his or her name on the books of the
Corporation.

           2.9       Closing of Transfer Books and Fixing Record Date.  For
the purpose of determining stockholders entitled to notice of or to vote at any
meeting of stockholders, or any adjournment thereof, or entitled to receive
payment of any distribution by the Corporation or a share dividend, or in order
to make a determination of stockholders for any other proper purpose, the Board
of Directors may provide that the stock transfer books shall be closed for a
stated period not to exceed twenty (20) days preceding such meeting. If the
stock transfer records shall be closed for the purpose of determining
stockholders entitled to notice of or to vote at a meeting of stockholders, such
records shall be closed for at least ten (10) days immediately preceding such
meeting. In lieu of closing the stock transfer books, the Board of Directors may
fix in advance a record date for any such determination of stockholders, such
date to be not more than ninety (90) days and, in case of a meeting of
stockholders, not less than ten (10) days prior to the date on which the
particular action requiring such determination of stockholders is to be taken.

           2.10      Proxies. A stockholder may vote either in person or by 
proxy executed in writing by the stockholder, or his or her duly authorized
attorney-in-fact. No proxy shall be valid after eleven months from the date of
its execution, unless otherwise expressly provided in the proxy.

           2.11      Voting of Shares in the Name of Two or More Persons. When
ownership stands in the name of two or more persons, in the absence of written
directions to the Secretary of the Corporation to the contrary, at any meeting
of the stockholders of the Corporation any one or more of such stockholders may
cast, in person or by proxy, all votes to which such ownership is entitled. In
the event an attempt is made to cast conflicting votes, in person or by proxy,
by the several persons in whose names shares of stock stand, the vote or votes
to which those persons are entitled shall be cast as directed by a majority of
those holding such stock and present in person or by proxy at such meeting. In
the event an attempt is made to cast conflicting votes by more than one person
and the votes are evenly split on any particular matter: (i) each faction may
vote the stock in question 

<PAGE>   5
ICARUS International, Inc.
Bylaws
Page 5


proportionally; or (ii) any person voting the stock or any beneficiary may apply
to a court of competent jurisdiction to appoint an additional person to act with
the persons voting the stock and the stock shall then be voted as determined by
a majority of those persons and the person appointed by the court. If the
written directions given to the Secretary shows that the interests are unequal,
a majority or even split for the purpose of this Bylaw is a majority or even
split in interest.

           2.12      Voting of Shares by Certain Holders. Shares standing in the
name of another corporation may be voted by an officer, agent or proxy as the
bylaws of such corporation may prescribe, or, in the absence of such provision,
as the board of directors of such corporation may determine. Shares registered
in the name of another held by a fiduciary may be voted by him or her, either in
person or by proxy, on proof of the fact that legal title to the stock has
devolved on him or her in a fiduciary capacity and that he or she is qualified
to act in that capacity. A stockholder whose shares are pledged shall be
entitled to vote such shares until the shares have been legally transferred into
the name of the pledgee, and thereafter the pledgee shall be entitled to vote
the shares so transferred, but this Bylaw does not affect the validity of any

Directors, other than those who may be elected by the holders of any class or

or required to be exercised or done by the stockholders.

           3.2       Change of Number. The number of directors may at any time 
be increased or decreased by a vote of a majority of the Whole Board of

prescribed by resolution of the Board of Directors or by resolution of such
committee. At least three (3) days' notice of the time and place of each meeting
shall be personally delivered, mailed, sent by facsimile with receipt confirmed
by telephone at the director's residence or principal place of business or given
by telephone to each member of the Board or such committee; provided, however, a
schedule of regular meetings may be provided to each director in the manner
specified above and no further notice of any such meeting(s) shall be required.
Such notice shall be deemed to be delivered when deposited in the mail so
addressed with postage prepaid. Neither the business to be transacted at, nor
the purpose of, any regular meeting need be specified in the notice or any
waiver of notice of such meeting. Regular meetings of the Board of Directors or
any committee may be held at the principal place of business of the Corporation
or at such other place or places, either within or without the State of
Maryland,

as the Board of Directors or such committee, as the case may be, may
from time to time designate. The annual meeting of the Board of Directors shall

of stockholders, for the purpose of organizing the Board, electing officers and
members of committees and transacting other business.

the person or persons calling such meeting may from time to time designate.
Notice of all special meetings of the Board of Directors shall be given to each
director by at least one (1) days' service of the same by facsimile with receipt
confirmed by telephone, telephone or personally, and by at least three (3) days'
service when delivered by mail at the address at which the director is most

business to be transacted at, nor the purpose of, the meeting.

                     (b)  Special meetings of any committee may be called
at any time by such person or persons and with such notice as shall be specified

           3.7       Quorum.

           (a)       A majority of the Whole Board of Directors of the 
Corporation, as such term is defined in the Articles of Incorporation, at the
time of a meeting of the Board of Directors shall be necessary at all meetings
to constitute a quorum for the transaction of business. At any meeting of the
Board, no action shall be taken (except adjournment, in the manner provided
below) until after a quorum has been established.

           (b)      The act of a majority of directors who are present at a 
meeting at which a quorum previously has been established (or at any adjournment
of such meeting, provided that a quorum previously shall have been established

regardless of whether or not a quorum is present at the time such action is
taken.

           (c)      In the event a quorum cannot be established at the 
beginning of a meeting, a majority of the directors present at the meeting, or
the director, if there be only one person, or the Secretary of the Corporation,
if there be no director present, may adjourn the

meeting from time to time until a quorum is present. Only such notice of such
adjournment need be given as the Board may from time to time prescribe.

           3.8      Waiver of Notice. Attendance of a director at a meeting of
directors shall constitute a waiver of notice of such meeting, except where a
director attends for the express purpose of objecting to the transaction of any
business because the meeting is not lawfully called or convened. A waiver of
notice signed by the director or directors, whether before or after the time
stated for the meeting, shall be equivalent to the giving of notice.

           3.9      Registering Dissent. A director who is present at a meeting 
of the Board of Directors at which action on a corporate matter is taken shall
be presumed to have assented to such action unless he or she announces his
dissent at the meeting and his dissent shall be entered in the minutes of the

action with the person acting as the secretary of the meeting, before the
adjournment thereof, or shall forward such dissent by certified mail, return
receipt requested, bearing a postmark from the United State Postal Service to
the Secretary of the Corporation within twenty four (24) hours after the
adjournment of the meeting. Such right to dissent shall not apply to a director
who voted in favor of such action or failed to make his or her dissent known at

may see fit, subject to such conditions as may be prescribed by the Board. An

Whole Board of Directors. It shall have and exercise all of the authority of the
Board of Directors, except in reference to amending the Articles of
Incorporation, declaring dividends or distributions on the capital stock of the
Corporation, issuing stock except as permitted by the MGCL Section 2-411(b),

thereof, or any other action requiring the approval of the stockholders, or

approved by a majority of the Whole Board of Directors, as such term is defined
in the Corporation's Articles of Incorporation, and at least a majority of the
members of the Audit Committee shall be directors who are not also officers of
the Corporation. The Audit Committee shall recommend independent auditors to the
Board of Directors annually and shall review the Corporation's budget, the scope

Committee. All committees so appointed shall keep regular minutes of the
transactions of their meetings and shall cause them to be recorded in books kept
for that purpose at the principal office of the Corporation. The designation of
any such committee, and the delegation of authority thereto, shall not relieve
the Board of Directors, or any member thereof, of any responsibility imposed by
law.

           (b)      Unless otherwise provided by the Board of Directors, a 
majority of the members of any committee shall constitute a quorum for the

salary for their service, and by resolution of the Board of Directors, a fixed
sum and expenses of attendance, if any, may be allowed for attendance at each
regular or special meeting of such Board. Members of standing or special
committees may be allowed like compensation for attending committee meetings.

           3.12     Action by Directors Without a Meeting. Any action required 
or which may be taken at a meeting of the directors, or of a committee thereof,
may be taken without a meeting if a consent in writing, setting forth the action
so taken or to be taken, shall be signed by all of the directors, or all of the
members of the committee, as the case may be and filed with the minutes of the
proceedings of the Board or committee. Such consent shall have the same effect
as a unanimous vote.

required or which may be taken at a meeting of directors, or of a committee
thereof, may be taken by means of a conference telephone or similar

           4.1      Certificates. Certificates of stock shall be issued in 
numerical order, and each stockholder shall be entitled to a certificate signed
by the Chairman of the Board, President or a Vice President, and the Secretary
or an Assistant Secretary or the Treasurer or an Assistant Treasurer, and may be
sealed with the seal of the Corporation or a facsimile thereof. The signatures
of such officers may be facsimiles if the certificate is manually signed on
behalf of a transfer agent, or registered by a registrar, other than the
Corporation itself or an employee of the Corporation. If an officer who has
signed or whose facsimile signature has been placed upon such certificate ceases
to be an officer before the certificate is issued, it may be issued by the
Corporation with the same effect as if the person were an officer on the date of
issue. Each certificate of stock shall state:

                     (a)  that is it issued by the Corporation;

                     (b)  the name of the person to whom issued;

                     (c)  the number and class of shares and the
designation of the series, if any, which such certificate represents;

other rights, voting powers, restrictions, limitations as to dividends,
qualifications, and terms and conditions of redemption and the differences of

set the relative rights and preferences of subsequent series, or a statement
that the Corporation shall provide such information to any stockholder upon
request and without charge.

           4.2       Transfers.

                     (a)  Transfers of stock shall be made only upon the
stock transfer books of the Corporation, kept at the principal office of the
Corporation or at its principal place of business, or at the office of its
transfer agent or registrar, by the person or person named in the certificate or
by the attorney lawfully constituted in writing representing such person or
persons and upon surrender of the certificate or certificates being transferred
which certificate shall be properly endorsed for transfer or accompanied by a
duly executed stock power. Whenever a certificate is endorsed by or accompanied
by a stock power executed by someone other than the person or persons named in
the certificate, evidence of authority

to transfer shall also be submitted with the certificate. All certificates
surrendered to the Corporation for transfer shall be cancelled.

                     (b)       The Board of Directors shall have the power and

stock of the Corporation.

institutions located within or without the State of Maryland as shall be
appointed by the Board of Directors. The Board shall also define the authority
of such transfer agents and registrars. The Board of Directors may, by
resolution, open a share register in any state of the United States, and may
employ an agent or agents to keep such register, and to record transfers of
shares therein.

           4.3      Registered Owner. Registered stockholders shall be treated 
by the Corporation as the holders in fact of the stock standing in their
respective names and the Corporation shall not be bound to recognize any
equitable or other claim to or interest in any share on the part of any other
person, whether or not it shall have express or other notice thereof, except as
expressly provided below or by the laws of the State of Maryland. The Board of
Directors may adopt by resolution a procedure whereby a stockholder of the
Corporation may certify in writing to the Corporation that all or a portion of
the shares registered in the name of such stockholder are held for the account
of a specified person or persons.

           4.4      Mutilated, Lost or Destroyed Certificates. In case of any
mutilation, loss or destruction of any certificate of stock, another may be
issued in its place upon receipt of satisfactory proof of such mutilation, loss
or destruction. The Board of Directors may impose conditions on such issuance
and may require the giving of a satisfactory open penalty bond with surety or
indemnity to the Corporation in such sum as they might determine and upon the
payment of the Corporation's reasonable costs incident thereto, or establish
such other procedures as they deem necessary.

           4.5      Fractional Shares or Scrip. The Corporation may but is not
obliged to (a) issue fractions of a share which shall entitle the holder to
exercise voting rights, to receive dividends thereon, and to participate in any
of the assets of the Corporation in the event of liquidation; (b) arrange for
the disposition of fractional interests by those entitled thereto; (c) pay in
cash the fair value of fractions of a share as of the time when those entitled
to receive such shares are determined; or (d) issue scrip in registered or
bearer form which shall entitle the holder to receive a certificate for a full
share upon the surrender of such scrip aggregating a full share, and unless
otherwise provided, does not entitle its holder to exercise voting rights,
receive dividends, or participate in the assets of the Corporation in the event
of liquidation.

                  Integrated Software. However ICARUS shall have the right to
                  develop software ("Customer Software") that contains Unit Cost
                  Estimating Software for a customer of ICARUS provided that

                  available product.

         E.       ICARUS hereby grants RICHARDSON the right to become an ICARUS
                  Sales Agent, with the non-exclusive right to market ICARUS

                  RICHARDSON Software ("Original RICHARDSON Source Code")
                  subject to the following:
<PAGE>   5
                  (i)      If ICARUS requests that an addition, deletion and/or
                           other change be made to the Original RICHARDSON
                           Source Code (hereafter "Modified RICHARDSON Source
                           Code"), that relates solely to the functional
                           operation of RICHARDSON'S Software then ICARUS shall
                           describe such change to RICHARDSON, whereupon
                           RICHARDSON shall have the option to either create the
                           Modified RICHARDSON Source Code or elect to have
                           ICARUS do so. If RICHARDSON elects to create the
                           Modified RICHARDSON Source Code itself but either
                           does not or cannot make the requested change within
                           the time frame requested by ICARUS, then ICARUS shall
                           have the right to create the Modified RICHARDSON
                           Source Code. The party creating the Modified
                           RICHARDSON Source Code shall, upon completion and
                           testing, give a copy to the other party.

                  (ii)     ICARUS is hereby permitted to integrate and/or
                           interface the Original RICHARDSON Source Code and/or
                           Modified RICHARDSON Source Code and/or RICHARDSON
                           Software, with ICARUS Software and Services; the
                           resulting integrated software hereby being deemed the
                           "Integrated Software", and any modifications to the
                           Original RICHARDSON Source Code or Modified
                           RICHARDSON Source Code made by ICARUS in conjunction
                           therewith being hereby deemed the "Integration Source
                           Code." RICHARDSON agrees at all times to cooperate
                           with ICARUS and/or assist ICARUS in performing the
                           interface and/or integration of RICHARDSON Software
                           and ICARUS Software and Services. Thereafter, ICARUS
                           shall be responsible for making and tracking such
                           additional changes as may be necessary in all future
                           versions thereof.

                  (iii)    RICHARDSON shall have the right to elect not to
                           incorporate the Modified RICHARDSON Source Code into
                           the RICHARDSON Software as marketed by RICHARDSON;
                           however, ICARUS shall nevertheless be permitted to
                           incorporate the Modified RICHARDSON Source Code into
                           the Integrated Software.

                  (iv)     Notwithstanding the foregoing, ICARUS shall also
                           retain the right to make changes to the Original
                           RICHARDSON Source Code or Modified RICHARDSON Source
                           Code that relates solely to copy and/or license
                           management using the ICARUS System Device (or any
                           substitute device utilized by ICARUS), and such
                           changes as may be required in order to integrate
                           RICHARDSON Software into ICARUS Software and Systems,
                           and which shall be deemed part of the Integration
                           Source Code.

                  (v)      RICHARDSON shall at all times retain sole ownership
                           and title to the Original RICHARDSON Source Code and
                           the Modified RICHARDSON Source Code, if created by
                           RICHARDSON.

                           this Agreement a worldwide non-exclusive right and
                           license, but not the obligation, to use and

                           the RICHARDSON trademarks, service marks, brand
                           names, logos, and other proprietary rights used by
                           RICHARDSON for the RICHARDSON Software and RICHARDSON
                           Database Products (the "RICHARDSON Marks") in
                           connection with the distribution, advertising and
                           promotion of the RICHARDSON Database Products,
                           RICHARDSON Software, and Integrated Software, subject
                           to the provisions of this Section 2 Paragraph I.

                  (ii)     ICARUS acknowledges and agrees that except for the
                           limited right to use the RICHARDSON Marks to the
                           extent herein setforth, ICARUS has no rights in the
                           RICHARDSON Marks. ICARUS acknowledges that RICHARDSON
                           owns and retains all proprietary rights in and to all
                           RICHARDSON Marks, and that ICARUS shall take no
                           action or
<PAGE>   7
                           make any registration that would otherwise convey or
                           grant an interest in said RICHARDSON Marks. ICARUS
                           agrees not to contest or take any action to contest
                           RICHARDSON's ownership of the RICHARDSON Marks, or to
                           use, employ or attempt to register any trademark,
                           service mark, or tradename in any country in the
                           world that is confusingly similar to the RICHARDSON
                           Marks.

                  (iii)    ICARUS agrees that RICHARDSON shall be the sole owner
                           of any and all goodwill in the RICHARDSON Marks built
                           up in the United States and in any country in which
                           the RICHARDSON Database Products, RICHARDSON
                           Software, and Integrated Software are distributed by
                           ICARUS.

                  (iv)     ICARUS shall take no action that impairs or otherwise
                           tarnishes the RICHARDSON Marks.

                  (v)      ICARUS shall require its Affiliates and Dealers to
                           adhere to the terms of this provision, and shall take
                           steps generally consistent with the monitoring of
                           ICARUS' own marks to ensure that its Affiliates and
                           Dealers use the RICHARDSON Marks in accordance with
                           the terms of the license herein.

                  (vi)     ICARUS agrees to cooperate (at no cost to ICARUS)
                           with RICHARDSON to protect RICHARDSON's ownership of
                           and interest in the RICHARDSON Marks. This
                           cooperation includes prompt notice to RICHARDSON of
                           instances known to ICARUS in which a third party is
                           using the RICHARDSON Marks without authorization.
                           RICHARDSON shall have the right, but not the
                           obligation, and shall bear all costs and expenses, to
                           (a) institute and prosecute any actions for
                           infringement of the RICHARDSON Marks throughout the
                           world; (b) defend any petition to cancel any
                           registration of the RICHARDSON Marks; (c) and oppose
                           any attempted use of or application to register any
                           mark confusingly similar to, or a colorable imitation
                           of, any of the RICHARDSON Marks throughout the world.
                           In the event that RICHARDSON elects not to exercise
                           the foregoing rights in any particular instance,
                           ICARUS may, at its cost and expense, exercise such
                           rights.

                  (vii)    Nothing contained in this Agreement shall be deemed
                           to grant to RICHARDSON any rights to use, sublicense
                           or otherwise, any trademarks, service marks, brand
                           names, logos, and other proprietary rights belonging
                           to ICARUS; and RICHARDSON agrees that ICARUS shall be
                           the sole owner of any and all goodwill in the
                           aforementioned, and RICHARDSON shall take no action
                           that impairs or otherwise tarnishes same.
<PAGE>   8
      J.       Nothing contained in this Agreement shall be construed as
               limiting rights that the parties may enjoy outside the scope
               of the rights granted and the obligations and restrictions set
               forth or treated herein.

low level of software integration across the foregoing disciplines, and desire
to develop and offer an integrated set of software applications that will
provide engineers and others with an environment in which to address process
simulation, equipment selection, equipment sizing and cost estimating.


         C. HYPROTECH has developed a proprietary flow sheet process simulation
program called HYSYS. Using object-oriented programming, HYSYS represents a
framework in which engineering applications can be implemented from conceptual
design through plant operation within a single environment. ICARUS owns the
rights to industry proven software and technology in the areas of design, cost
estimating, scheduling, computer aided engineering (CAE), computer aided design
(CAD), and expert system technologies.

         D. HYPROTECH and ICARUS are entering into this Agreement, in order to
integrate appropriate portions of their respective technologies and produce
Jointly Developed Products (as hereinafter defined), which address engineering
work processes in the Chemical Processing Industry, where HYSYS and/or HYSIM are

offerings, both parties may elect to market the other party's products (i.e.,
excluding Jointly Developed Products) through their direct sales force, dealers,
distributors, sales agents, or network of business partners, after sales
certification training in the appropriate product by the party that has
marketing rights to such product. [*]Where there exists documented evidence of
prior sales activity with the account in question by the party that has
marketing rights to the product, there shall be no finder's fee due.

         7.       Resource Commitment and Revenue Share.

                  Each party hereby warrants to the other that the technology
provided by said party to any Jointly Developed Product and/or used in the
development thereof, does not and shall not infringe upon any third party United
States and Canadian intellectual property rights including but not limited to
copyright, patent, trade mark and trade secrets. Each party agrees to indemnify,
defend and hold the other party harmless with respect to any proceeding brought
by a third party against the other party, alleging infringement of intellectual
property rights. As a condition thereof, each party indemnified hereunder agrees
to give the indemnifying party prompt, written notice of any such claim, suit or
proceeding, and permit the indemnifying party to defend such claim, suit or
proceeding. Under this provision, the indemnifying party shall have control over
the defense of any such claim, suit or proceeding, including appeals,
negotiations, and rights to settle or effect a settlement or compromise thereof,

respective software components, provided (i) the technology is properly licensed
by that party for the application and subsequent re-license in the marketplace
to Customers, (ii) each licensing party informs the other party to this
Agreement that licensed technology is being used with an adequate description of
same and the source thereof, and (iii) any costs of such licensing are (a) borne
solely by the party licensing such technology with respect to technology
licenses existing as of the signing of this agreement, the cost of which is
deemed to be already included in the determination of the price schedule and
revenue sharing provisions of this Agreement, and (b) must include any price
adjustments and/or revenue sharing adjustments necessary to be reflective of the
costs of licensing any such technology as may be negotiated by the parties.

other party's consent, which consent will not be unreasonably withheld. It is
agreed that no subcontracting to a direct or indirect competitor of either party
will occur. In order to subcontract, the other person or entity providing the
services must sign a written agreement, in advance, to be bound by all
intellectual property protections and other indemnifications and protections
afforded to the parties hereunder, and said agreement must include terms
approved by both parties which ensure that both HYPROTECH and ICARUS will retain
exclusive rights to the developed intellectual property and technology. Any
technology developed by a subcontractor will be covered under the terms of this
Agreement.

party shall be permitted to exercise all available remedies, and/or terminate
this Agreement pursuant to paragraph 20 hereof.

                  17.3 Equitable Relief: Notwithstanding the foregoing, nothing
herein shall be deemed to preclude either party from seeking equitable relief of
an appropriate nature, including injunctive relief, against the other party,
with respect to any violation of this Agreement which relates to the
unauthorized release of technology or Proprietary Information or infringement
upon intellectual property rights, without waiting the ninety (90) day period
set forth in Section 17.2 above.

contract will remain in force notwithstanding a change in ownership. However, if
a controlling interest (51%) in one party is acquired by a direct competitor of
the other party or if the parent of one party acquires a controlling interest in
a competitor of the other party, this Agreement can be terminated at the option
of the other party, and the other party will have the right to continue the

levels of management as necessary. Either party may notify the other party in
writing, of the existence of a non-material dispute requiring resolution,
whereupon the parties shall have thirty (30) days within which to resolve the
dispute in the manner hereinabove set forth. In the event the parties are unable
to resolve the dispute within said thirty (30) day period or such additional
period of time as to which the parties have agreed in writing, then either party
may invoke and demand binding arbitration pursuant to the rules of the American
Arbitration Association then in effect. If the parties are unable to agree to
the materiality of the breech or dispute, it shall be deemed material for the
purpose of this Section 19. Notwithstanding the foregoing, the parties may agree
in writing to have any material dispute also resolved by arbitration in
accordance with the rules of the American Arbitration Association or pursuant to
any other means. Arbitration under this paragraph shall be held in the State of
Maryland. Nothing herein shall be deemed to limit either party's remedies at law
or in equity with respect to any material breach of this Agreement.

                           (b)      Terminating the term of this Agreement
immediately.

                           In the event of termination due to Default, the
non-defaulting party has the right to continue the development and marketing of
Jointly Developed Products and any new products which may or may not be deemed
competitive with Jointly Developed Products, notwithstanding Section 11.2
Competition.

                  20.4     Responsibilities Upon Termination:

name existing immediately prior to termination or any other name, except to the
extent necessary for the fulfillment of license agreements existing as of the
date of termination, nor shall either party reproduce any Jointly Developed
Product or prepare derivative works therefrom. Notwithstanding the foregoing, in
the event of a termination of this Agreement pursuant to Section 18 above based
upon a change in ownership or pursuant to Section 20.3 above based on a material
default, then the other party shall continue to have the right to market Jointly
Developed Products; provided, however, the provisions of Sections 6.3, 7.4, 7.6
and 7.7 shall be deemed applicable to such post-termination sales of Jointly
Developed Products.

                  (iii) Notwithstanding termination of the term of this
Agreement, all provisions of this Agreement pertaining to the ownership of
technology, Proprietary Information, intellectual property rights,
indemnifications, and other protections shall remain in full force and effect.

Agreement will commence on the date first written above and will terminate on
the fourth anniversary thereof unless extended in writing by mutual agreement of
the parties.

                 b. Either party may at any time, upon six months prior written

         3.       JOINTLY DEVELOPED PRODUCTS

                  a. Products. The parties hereby agree to develop and market
Jointly Developed Products to provide specific capital and operating cost
estimates to companies studying technology selection or upgrade for construction
and investment in selected product areas. Jointly Developed Products will
initially include a "Business Model" and a "Project Model." Jointly Developed
Products may also include a "PEPCOST/ICARUS Cost Estimation Program." The
following is a general description of these products:

                     i. Business Model: The Business Model will be a software
program that will contain several Categories of Information relating to a
particular process design. The Business Model will be an interactive multi-media
electronic document that is driven from an individual PEP process reflecting the
PEP technical content and the process estimation (capital and operating) cost
results of the ICARUS Technology. Because of the vast quantity of information to
be contained in a Business Model, the parties anticipate that the media used for
product delivery will be CD-ROM. There will also be a summary narrative that
describes the various subsets of Categories of Information referred to in the
Business Model. Examples of narratives and types of information may include
items such as Process Flow Diagrams (PFD's),


                                        5
<PAGE>   6
Piping & Instrumentation Diagrams (P&ID's), Scope of Work Narratives,
Contingency Analyses, and other topics suitable for the particular process.

         ii. Project Model: The Project Model will be supplied on software media
that contains the PEP-based input data for ICARUS 2000 and ICARUS Process
Evaluator (IPE) for a specific process that will enable the customer who is a
user of ICARUS 2000 and/or ICARUS Process Evaluator (IPE) to prepare certain
project information (cost estimate, schedule of engineering and construction)
for the particular process. There may also be a Project Model offering that
includes a license of ICARUS 2000.

         iii. PEPCOST/ICARUS Cost Estimation Program: The parties will explore
the viability of a PEPCOST/ICARUS modified cost estimation program targeted at
serving the R&D/planning/technology development cost estimation needs of both
operating companies and E&Cs. The parties anticipate that this product will
essentially provide the PEPCOST level of detail and presentation in a mode
compatible with more powerful, more detailed versions of some ICARUS software
(e.g., IPE, Icarus 2000). The utilities consumption estimate module of PEPCOST
is a particular feature that may be included in this cost estimation program.

    b.   Development Schedule. The anticipated development schedule for the
Business Model and Project Model is as follows, and is expected to begin after
this Agreement has been signed by both parties:

         i. Prototype for ethyl benzene (EB): June-September 1997 alpha, beta
testing by both parties with selected potential and existing clients. The alpha
prototype will use the ICARUS 2000 run (report) based on the PEP input of design
bases and major equipment listings for Mobil/Badger EB process. The GUI screens
developed by ICARUS, augmented with an icon for production cost information,
will be used as the "front end." SRIC will provide current Mobil/Badger EB
production cost information for use in the prototype model.

         ii. Additional product schedule: To be determined by September 1997.
The parties intend to develop up to 10-20 products (with multiple processes)
each six months during the term of this Agreement, subject to each party's
review and customer acceptance. SRIC will provide the PEP input of design bases
and major equipment listings for each product, and ICARUS will run the initial
cost estimations.

         iii. Custom client requests: The parties will use their best efforts to
develop mechanism/pricing to handle custom client requests for evaluations.

    c.   Marketing. The parties agree to jointly market the Jointly Developed
Products on a worldwide basis by utilizing the ICARUS Marketing Channels and the
SRIC Marketing Channels. The parties will develop a collaborative marketing plan
to coincide with the


                                        6
<PAGE>   7
initial marketing of the beta version of the first Jointly Developed Product.
The marketing plan is expected to detail sales strategy and joint marketing
activities such as press releases, trade shows, technology conferences, user
conferences, and technical articles. Subject to Section 6(h) and 7(b)(iii), the
parties will market the Jointly Developed Products under the joint names of each
party with each party's name receiving equal prominence on all packaging,
documentation and other marketing and sales materials.

         4.       JOINT MARKETING OF EXISTING ICARUS PRODUCTS AND SRIC'S
                  PEP PRODUCTS

                  Each party will use its reasonable efforts to identify leads
for the existing products of the other party, to be turned over to the party for
follow-up. The parties anticipate that they will jointly market each other's
products as follows:

                  a.       Within the first month of the term of this Agreement,
each party will, subject to Section 6(h):

                           i.       Notify its existing customer base of this
Agreement. Marketing vehicles anticipated to be used include ICARUS' newsletter
and the PEP Bulletin, a PEP Special Notice, and other ongoing market
communication lines.

                           ii.      Reference each other in promotional
materials.

                           iii.     Exchange customer lists.  Customer lists
provided are anticipated to include the names of the current PEP Program and
ICARUS licensee contacts. The disclosure and use of each party's customer lists
will be subject to Section 9 (Confidential Information).

                           iv.      Provide basic sets of promotional materials
to each another in electronic and print form.

                  b.       Within the first quarter of the term of this
Agreement, each party will:

                           i.       Provide hotlinks to the other's web pages
(ICARUS' and PEP's).

                           ii.      Agree upon new sets of joint promotional
material referencing each other's existing products.

         5.       OTHER DEVELOPMENT ACTIVITIES

                  In addition to the marketing and development activities
described above, two additional development activities are anticipated to be
pursued under this Agreement, as follows:


                                        7
<PAGE>   8
         a. Reengineering of PEP Report preparation to incorporate ICARUS (or
ICARUS/PEPCOST) cost estimating procedures and Icarus' simulator or CAD links.
This development will constitute more of a "behind the scenes" operation, but is
expected to be potentially valuable to ICARUS and SRIC for insights into new
ways of working, and building an extended value network.

               i.       The parties expect to target 1-3 "New" reports in the
first year of this Agreement.

               ii.      SRIC's PEP staff will lead this development, with an
Icarus contact on the project team.

         b. Joint SRIC/ICARUS development of products outside the PEP domain,
such as mines and minerals, biotechnology, and electronics. The parties will
undertake a review of such additional products at six month intervals.
Initiation will require the consent of both parties. If such products proceed to
the product development and marketing stages, the parties will amend this
Agreement accordingly.

    6.   PERFORMANCE OF MARKETING AND DEVELOPMENT ACTIVITIES

         a. Management Committee; Contact Persons. The marketing and development
activities contemplated hereunder shall be carried out under the ultimate
direction of a management committee comprised of four to six representatives,

Proprietary Information is necessary for the carrying out of the activities
contemplated by this Agreement. Therefore, the parties agree that during the
term of this Agreement, and for a period of two (2) years after its expiration
or earlier termination, each party shall maintain the confidentiality of any
Proprietary Information disclosed to it. Neither party shall use the other
party's Proprietary Information for any purpose except in connection with the
activities contemplated by this Agreement. Neither party will disclose or make
accessible to any person or business entity of any type any Proprietary
Information that was disclosed by one party to the other unless required to do
so by judicial or administrative process (provided that the recipient shall
promptly notify the discloser and shall allow the discloser a reasonable time to
oppose such process before making disclosure). The parties agree that access to
any disclosed Proprietary Information will be limited to employees or
subcontractors who have a need to know such Proprietary Information for the
purpose of carrying out the terms of this Agreement and who have agreed in
writing to receive it under terms at least as restrictive as those contained
herein. The parties further agree that any Proprietary Information will be
safeguarded by the recipient with the same degree of care it would use for its
own proprietary or confidential information. Each party will immediately notify
the other of any unauthorized use or disclosure of the Proprietary Information
and will assist the other in remedying such unauthorized use or disclosure.

                  b. Each party agrees that a breach by that party of this
Section 9 will cause irreparable damage to the other party for which the
recovery of monetary damages would be inadequate, and therefore specifically
agrees that such other party is entitled to obtain temporary, preliminary, and
permanent injunctive relief to protect its rights hereunder, in addition to any
and all other remedies available at law or equity.

                  c. This section shall not apply to information: (i) that is or
becomes available to the public other than by breach of this Agreement; (ii)
that is rightfully received by the recipient from a third party without
confidentiality limitations; (iii) that the recipient can demonstrate by clear
and convincing evidence was independently developed by the recipient's employees
or subcontractors without access to the Proprietary Information; or (iv) that is
shown by written evidence to have been known by the recipient without any
restrictions as to use or disclosure prior to the disclosure of the Proprietary
Information to the recipient.

                  d. The Proprietary Information disclosed by one party to the
other, and any copies thereof created by the recipient, shall remain the
property of the discloser. Upon the expiration or earlier termination of this
Agreement, the recipient shall within fourteen (14) days return to the
discloser, or at the discloser's election destroy, all Proprietary Information
of the discloser, and all copies thereof, and provide a written accounting to
the discloser of such return or destruction unless retention of such information
is necessary to fulfill the discloser's obligation


                                       16
<PAGE>   17
to continue to provide support to end-users pursuant to Section 6(d), in which
case the recipient shall return or destroy such information and provide such
accounting at the earliest possible time when such retention is no longer
necessary.

                  e. Except as otherwise provided herein, no license or
conveyance of any rights in any Proprietary Information or Intellectual Property
Rights is granted or implied by the disclosure of Proprietary Information under
this Agreement.

         10.      OTHER ACTIVITIES

                  During the term of this Agreement, (i) each party agrees not
to develop products that will directly compete with the Jointly Developed
Products, and (ii) each party agrees not to license the ICARUS Technology (in
the case of ICARUS) or the SRIC Technology (in the case of SRIC) to third
parties to use in the development, production, marketing, sale, license and
other distribution of products that will directly compete with the Jointly
Developed Products. Subject to the foregoing, each party may (i) pursue other
business opportunities that integrate its own Technology with other products and
(ii) engage in or possess an interest in other business ventures of every nature
and description, independently or with others, and neither party shall have any
right by virtue of this Agreement in or to such other business opportunities or
ventures, or in or to the income or profits derived therefrom.

         15.      MISCELLANEOUS

                  a.       Dispute Resolution.

                           i.     The parties will attempt in good faith to
resolve through negotiation any dispute, claim or controversy arising out of or
relating-to this Agreement. Either party may initiate negotiations by providing
written notice in letter form to the other party, setting forth the subject of
the dispute and the relief requested. The recipient of such notice will respond
in writing within five days with a statement of its position on and recommended
solution to the dispute. If the dispute is not resolved by this exchange of
correspondence, then representatives of each party with full settlement
authority will meet at a mutually agreeable time and place within ten days of
the date of the initial notice in order to exchange relevant information and
perspectives, and to attempt to resolve the dispute.

                           ii.    If the dispute is not resolved by these
negotiations, the parties agree that any and all disputes, claims or
controversies arising out of or relating to this Agreement shall be submitted to
J.A.M.S./ENDISPUTE ("JAMS"), or its successor, for non-binding mediation, and if
the matter is not resolved through mediation, then it shall be submitted to
JAMS, or its successor, for final and binding arbitration. Either party may
commence mediation by providing to JAMS and the other party a written request
for mediation, setting forth the subject of the dispute and the relief
requested. The parties will cooperate with JAMS and with one another in
selecting a mediator from JAMS's panel of neutrals, and in scheduling the
mediation proceedings. The parties covenant that they will participate in the
mediation in good faith, and that they will share equally in its costs. All
offers, promises, conduct and statements, whether oral or written, made in the
course of the mediation by any of the parties, their agents, employees, experts
and attorneys, and by the mediator or any JAMS employees, are confidential,
privileged and inadmissible for any purpose, including impeachment, in any
arbitration or other proceeding involving the parties, provided that evidence
that is otherwise admissible or discoverable shall not be rendered inadmissible
or non-discoverable as a result of its use in the mediation. Either party may
initiate arbitration with respect to the matters submitted to mediation by
filing a written demand for arbitration at any time


                                       21
<PAGE>   22
following the initial mediation session or 45 days after the date of filing the
written request for mediation, whichever occurs first. The mediation may
continue after the commencement of arbitration if the parties so desire. Unless
otherwise agreed by the parties, the mediator shall be disqualified from serving
as arbitrator in the case. The provisions of this clause may be enforced by any
court of competent jurisdiction, and the party seeking enforcement shall be
entitled to an award of all costs, fees and expenses, including attorneys fees,
to be paid by the party against whom enforcement is ordered.

         iii. If the dispute is not resolved by negotiations or mediation, the
parties agree that any and all disputes, claims or controversies arising out of
or relating to this Agreement shall be submitted to final and binding
arbitration before JAMS, or its successor, pursuant to the United States
Arbitration Act, 9 USC Sec. 1 et seq. in the City and County of San Francisco.
The arbitration will be conducted in accordance with the provisions of JAMS's
Streamlined Arbitration Rules and Procedures in effect at the time of filing of
the demand for arbitration. The parties will cooperate with JAMS and with one
another in selecting an arbitrator from JAMS's panel of neutrals, and in
scheduling the arbitration proceedings. The parties covenant that they will
participate in the arbitration in good faith, and that they will share equally
in its costs. The provisions of this clause may be enforced by any court of
competent jurisdiction, and the party seeking enforcement shall be entitled to
an award of all costs, fees and expenses, including attorneys' fees, to be paid
by the party against whom enforcement is ordered. Judgment upon any arbitration
award may be entered in any court having jurisdiction. Either party may bring an
action, including a summary or expedited proceeding, to compel arbitration of
any controversy or claim to which this Agreement applies in any court having
jurisdiction over such action. If JAMS or its successor is unable or legally
precluded from administering the arbitration, then the American Arbitration
Association will serve.

         iv. Each party agrees to keep all disputes and arbitration proceedings
strictly confidential, except for disclosures of information required in the
ordinary course of business of the parties or by applicable law or regulation.

             b. Governing Law. This Agreement shall be governed by and construed
in accordance with the laws of the State of California without regard to its
conflicts of laws principles.

             c. Notice. Any notice or other communication required or desired to
be given under this Agreement shall be in writing and in the English language

business days after being deposited in the mail as provided above.

         d. Severability. If a court of competent jurisdiction shall declare
that any provision of this Agreement is invalid, illegal, or incapable of being
enforced in whole or in part, the remaining conditions and provisions or
portions hereof shall nevertheless remain in full force and effect and
enforceable, and no provision shall be deemed dependent upon any other covenant

which consent shall not be unreasonably withheld.

         g. Waiver. The failure of either party to insist upon strict
performance of any of the terms, conditions, and provisions of this Agreement
shall not be construed as a waiver or relinquishment of future compliance
herewith or with any other term, condition, or provision hereof, and said terms,
conditions, and provisions shall remain in full force and effect. No waiver of
any term or condition of the Agreement on the part of either party shall be
effective for ANY purpose whatsoever unless such waiver is in writing and signed

purpose given.

enterprise between the parties.

Update or Upgrade. In the absence of such written notice from ICARUS, Primavera
shall, in fulfillment of Kit Orders from ICARUS, continue to ship to ICARUS

                                 PRICES; PAYMENT

      5.01 Prices to ICARUS.

            (a) ICARUS shall pay to Primavera the following license fees:

                  (i) for each copy of a Software Product licensed for operation
by End User on a single user system, a Base License Fee (as adjusted in
subparagraph (b) below) based upon the number of single user systems as set
forth in the "Single User Systems" license fee chart in Appendix A, and subject
to the additional terms and conditions contained therein; and

                  (ii) for each copy of a Software Product licensed for
operation by End User on network systems, a Base License Fee (as adjusted in
subparagraph (b) below) based upon the number of simultaneous users in the End
User organization, as set forth in the "LAN" license fee chart in Appendix A,
and subject to the additional terms and conditions contained therein; and

                  [*]

                  In the event that an Enhancement Kit commercially released by
Primavera contains an Update, not an Upgrade, ICARUS shall pay to Primavera for
each Enhancement Kit only the shipping costs incurred by Primavera in furnishing
such Enhancement Kit to ICARUS.

                  (iv) The Base License Fees set forth in subparagraphs (i) and
(ii) above shall be adjusted for inflation as set forth in subparagraph (b)
below, and all pricing derived therefrom shall be likewise adjusted.

            (b) Commencing with calendar year 1996, the adjusted Base License
Fee payable by ICARUS to Primavera for each additional copy of a Software
Product licensed to an End User shall consist of the Base License Fee for each
such copy, adjusted as of the commencement of each License Year during the term
hereof, by any change in the Index now known as the United States Bureau of
Labor Statistics, Consumer Price Index for all Urban Consumers, Washington, D.C.
Metropolitan Area (1982-84 = 100) (hereinafter referred to as the Index), or its
successor (or if discontinued its most nearly comparable

successor) Index. Such adjustment shall be made by adding to the Base License
Fee, the product of the Base License Fee multiplied by a fraction

                  (i) the numerator of which is the difference between the Index
figure for the latest month of January for which the index is available at the
time of invoicing and the Index figure for the month of January for the First
License Year, and

                  (ii) the denominator of which is the Index figure for the
month of January of the First License Year.

       The result of the foregoing computation shall constitute the adjusted
annual Base License Fees payable by ICARUS for each additional copy of a
Software Product licensed by ICARUS during the then current License Year. In the
event such Index is discontinued with no successor or comparable Index, then the
parties shall attempt to agree upon a substitute formula for the determination
of such License Fee adjustments in the basic License Fee to be paid hereunder,
but if they are unable to agree upon a substitute formula within thirty (30)
days, then the matter shall be determined by arbitration in accordance with the
then applicable rules of the American Arbitration Association. However, any such
substitute formula for License Fee adjustments whether arrived at by agreement
of the parties or by arbitration, shall require such adjustments to be
calculated and effected on the annual basis hereinbefore set forth.

      5.02 End User Identification Reports; Forecasts.

            (a) ICARUS shall submit to Primavera within thirty (30) days
following the last day of each ICARUS corporate quarter, a quarterly report
setting forth the names and addresses of each End User to which ICARUS, its
Affiliate or Dealers distributed a Software Product or an Enhancement Kit during
such quarter.

      5.03 Payments by ICARUS.

            (a) ICARUS shall pay to Primavera the license fees payable pursuant
to Paragraph 5.01 for each copy of a Software Product or Enhancement Kit
licensed to an End User within thirty (30) days following the last day of the
ICARUS corporate quarter during which such Software Product or Enhancement Kit
was licensed.

      5.04 Interest. Interest shall accrue on any delinquent amounts owed by
ICARUS to Primavera hereunder at the rate of one and one-half percent (1.5%) per
month, or the maximum rate permitted by applicable law, whichever is less.

      5.05 Taxes. ICARUS shall be responsible for and shall pay any and all
taxes, duties, withholdings or similar charges that are due and payable by
ICARUS directly to any governmental authority as a result of the distribution or
licensing of the Software Products, 


                                     - 12 -
<PAGE>   13
including all sales, user, value-added, excise, personal property or other
similar taxes imposed by any local, state or federal government or regulatory
agency of any country.

      5.06 Records; Audit.

            (a) ICARUS shall maintain complete and accurate records sufficient
to permit the computation of the license fees payable hereunder to Primavera.
ICARUS shall, upon ten (10) days advance written notice by Primavera, but not
more frequently than once each calendar year, permit reasonable inspection of
such records by Primavera or its accountants at the offices of ICARUS during
normal working hours. Primavera shall maintain in confidence and not use or
disclose to third parties any of the information contained in or derived from
such records without the prior written consent of ICARUS.

            (b) The cost of any audit shall be borne solely by Primavera, except
that if any audit reveals an underpayment by ICARUS of royalties for any quarter
of ten (10%) percent or more, ICARUS shall reimburse Primavera for all
reasonable costs associated with the audit and Primavera shall have the right to
audit the records maintained by ICARUS every six months from that time forth. If
any audit reveals an understatement of ICARUS of the license fees due hereunder,
ICARUS shall pay the amount of the understatement within ten (10) days of
receiving written notice from Primavera, which shall include a copy of the audit
report. If any audit reveals that ICARUS has overpaid the license fees, the
amount of the overpayment shall be applied to reduce the amount of the next
payment due from ICARUS, or at the election of ICARUS, shall be paid to ICARUS
within ten (10) days. Nothing herein shall be deemed to preclude ICARUS from
disputing the results of such audit.

            (c) This provision shall survive for one (1) year following the
expiration or termination of this Agreement.

                                   ARTICLE VI
                       TECHNICAL SUPPORT; CONFIDENTIALITY

      6.01 Support to End Users. During the term of this Agreement, Primavera
shall offer to End Users such technical support services as Primavera makes
available to other end users of the Licensed Software at a price and under other
terms and conditions that are substantially the same as those offered by
Primavera to other similarly situated end users, including the applicability of
Primavera's technical support policies with respect to superseded versions of
the Licensed Software; provided, however, Primavera shall not offer, sell or
distribute Enhancement Kits directly to End Users, regardless of whether they
subscribe to Primavera's technical support services. The parties acknowledge and
agree that ICARUS, its Affiliate and Dealers shall have sole opportunity and
responsibility to order such Enhancement Kits from Primavera and distribute them
to End Users.

       6.02 Support to ICARUS. Nothing in this Agreement shall be construed to
obligate Primavera to furnish technical support, maintenance services or
training of any kind to 


                                     - 13 -
<PAGE>   14
ICARUS or to its Affiliate and Dealers, provided, however, any such support,
maintenance or training shall upon request, be provided at Primavera's
convenience to ICARUS at no greater charge than Primavera's charges its own
customers.

      6.03 Confidentiality.

            (a) Each party may disclose to the other information concerning its
Confidential Information as may be necessary to further the performance of this
Agreement. Each party agrees to treat the other's Confidential Information in
the manner prescribed herein.

            (b) Primavera and ICARUS shall protect the other's Confidential

agents required to have knowledge of same to perform their duties pursuant to
this Agreement. Each party shall require each such employee or agent to enter

Information to such employee or agent. Each party shall treat the Confidential
Information of the other party with the same degree of care as it protects its
own Confidential Information, and in no case less than a reasonable degree of
care.

                  (ii) Except as may specifically be permitted herein, upon the
termination of this Agreement, each party shall return to the other, or if so
requested, destroy all Confidential Information in the other's possession or
control, except such Confidential Information as may be reasonably necessary to
exercise the rights that survive the termination of this Agreement, but solely
to the extent and for the duration necessary.

            (c) The foregoing obligations of confidentiality shall not apply
with respect to either party's Confidential Information to the extent that it:

                  (i) is within or later falls within the public domain
through no fault of the party receiving the Confidential Information; or

                  (ii) is, or becomes, available to the receiving party from
third parties who, in making such disclosure, have breached no written
confidentiality agreement, fiduciary or other duty; or

                  (iii) is previously known by the receiving party; or

United States patent, copyright, trademark or other intellectual property right,
provided that Primavera receives prompt written notice of any such claim from
ICARUS, and Primavera is afforded the opportunity to exercise sole control of
the defense and all negotiations pertaining to such claim. Primavera shall also

                                  ARTICLE VIII
                                TERM; TERMINATION

      8.01 Term. This Agreement shall become effective as of the date first
written above and continue for an initial term of ten (10) years, unless sooner
terminated as provided herein. Thereafter, either party may terminate this
Agreement upon ninety (90) days advance written notice to the other party.

      8.02 Termination for Material Breach. Either party may, at its option,
terminate this Agreement in the event of a material breach by the other party.
Such termination may be effected only through a written notice to the other
party, specifically identifying the breach or breaches on which termination is
based. Following receipt of such notice, the party in breach shall have sixty
(60) days to cure such breach or breaches, said cure period to proceed
simultaneously with the dispute resolution procedure, if any, conducted pursuant
to Paragraph 9.12 hereof, and this Agreement shall terminate in the event that
such cure is not made by the end of such period. In the event that the parties
dispute either the existence of a material breach or the adequacy of attempted
cure, and either party submits such dispute to arbitration under Paragraph 9.13
hereof, the termination shall not be deemed effective until the arbitrator
renders a final decision finding an uncured material breach, provided, however,
that the termination shall be deemed effective if arbitration pursuant to
Paragraph 9.13 hereof is not initiated within fifteen (15) days after the
progressive dispute negotiation procedures under Paragraph 9.12 hereof are
complete. Either party may cure an alleged breach without waiving its right to
dispute resolution and arbitration as herein set forth, and shall be entitled as
part of a favorable arbitrator's decision to be compensated for payments made to
effect such cure or the payments due for Licensed software or services
delivered, as the case may be, to which it would have been entitled under this
Agreement.

      8.03 Bankruptcy. If either party files a petition in bankruptcy (or is the
subject of an involuntary petition in bankruptcy that is not dismissed within
sixty (60) days after the effective filing date thereof); or is or becomes
insolvent; or enters into any formal arrangement with its creditors, or ceases
doing business in the ordinary course; or admits 


                                     - 17 -
<PAGE>   18
of a general inability to pay its debts as they become due; then the other party
shall have the right to terminate this Agreement upon thirty (30) days written
notice.

      8.04 Survival. Upon termination of this Agreement, ICARUS, its Affiliate
and Dealers may distribute to End Users their remaining inventory of Software
Products, provided that ICARUS remit to Primavera all license fees due and
payable hereunder by reason of the distribution of such remaining inventory. End
Users as of the effective date of expiration or termination of this Agreement
and End Users that license the remaining inventory of Software Products pursuant
to this Paragraph 8.04 shall have a continuing right to use the Licensed
Materials in accordance with the terms of Primavera's End User License.
Paragraphs 3.03, 3.04, 3.11, 6.03, 7.08, 7.10 and 8.04, and Articles VII and IX
hereof shall also survive the termination of this Agreement.

                                   ARTICLE IX
                                  MISCELLANEOUS

time shall either party make commitments or incur any charges or expenses for or

right, upon reasonable notice, to examine Landlord's books and
<PAGE>   8
records with respect to the Operating Costs at the management office during

event the review or audit reveals an overpayment by Tenant of its share of
Operating Costs in excess of ten percent, Landlord shall promptly reimburse
Tenant the reasonable costs and expenses incurred to conduct such review or
audit. In the event the audit reflects an underpayment by Tenant, Tenant shall
promptly pay any additional amount(s) due to Landlord for Tenant's Pro Rata

the part of the Leased Premises so taken or sold, effective as of the date

not commercially viable to Landlord in Landlord's sole opinion, either Tenant in
the case of (i), or Landlord in the case of (ii), may terminate this Lease by
notice to the other party within 30 days after the terminating party receives
written notice of the portion to be taken or sold. Such termination shall be
effective 180 days after notice thereof, or when the portion is taken or sold,
whichever is sooner. All condemnation awards and similar payments shall be paid
and belong to Landlord, except any amounts awarded or paid specifically to
Tenant for removal and reinstallation of Tenant's trade fixtures, personal
property or Tenant's moving costs.

of this Lease the spaces described in Article 1.1(j). Said parking spaces shall
be made available to Tenant on an allocated basis and Tenant agrees to comply
with such reasonable rules and regulations as may be made by Landlord from time

contractors, licensees or invitees are deemed by Landlord to be contributing to
such condition, to charge to Tenant as Rent that portion of the cost thereof

reasonable discretion, change the location and nature of the parking spaces
available to Tenant, provided that after such change, there shall be available

<PAGE>   27
Tenant the same number of spaces as available before such change. The provisions

         2. Construction Documents; Payments

         2.01 An outline of the Leased Premises is attached hereto and made a
part hereof as Schedule 1. A preliminary floor plan of the Leased Premises will

delivering written notice to the other. Tenant acknowledges that Landlord's sole
monetary obligation is to pay the costs attributable to the construction of the
Leasehold Improvements, up to an aggregate maximum limit of $20.00 per square
foot of Tenant's Square Footage (the "Allowance"), and Tenant shall pay all
other costs of the construction of the Leasehold improvements in excess of the
Allowance ("Tenant's Share"). Landlord acknowledges and agrees that the

including all architectural services, engineering fees, preparation of working
drawings, permit fees and other related services (including overtime and other
expenses incurred to expedite the construction of the Leasehold Improvements to
meet the Lease Commencement Date), the installation of additional heating,
ventilating and air conditioning units and other special installations, and that
a portion of the Allowance (up to $2.00 per square foot of Tenant's Square
Footage) may be used to fund the installation of telephone and computer wiring,
moving and other related expenses incurred by Tenant in relocating its offices

addition, all costs attributable to changes and variations from the Construction
Documents in excess of the Allowance (including, without limitation, any fees

         shall be carried out by Landlord and its agents and contractors under
         the sole direction of Landlord without the imposition of a fee for
         Landlord's supervision or management of the construction process within
         the scope of the work originally specified in the Construction
         Documents. Tenant shall cooperate with Landlord and its agents and
<PAGE>   29
         contractors to promote the efficient and expeditious completion of the
         Leasehold Improvements; and

         (b) Landlord agrees to construct the Leasehold Improvements in
         accordance with the Construction Documents, provided Tenant has
         complied with all the applicable provisions of this Schedule and the
         Lease.

         3.02 If there are any changes in the Leasehold Improvements requested
by, or on behalf of, Tenant from the work as reflected in the Construction
Documents, each such change must receive the prior written approval of Landlord,
and Tenant shall bear the cost of all such changes in excess of the Allowance.

         3.03 Landlord shall have no obligation to commence construction of any
work in the Leased Premises until (a) Tenant has approved the Construction
Documents and the Final Cost for the construction of the Leasehold Improvements
as required by the provisions hereof, and (b) Landlord shall have received
Tenant's advance payment in an amount equal to the Tenant's Share, if any.

         4. Lease Commencement Date

         4.01 Landlord shall notify Tenant when Substantial Completion has been
achieved and the Lease Commencement Date shall be established as set forth in
the Lease. Notwithstanding anything to the contrary contained in the Lease or
this Schedule, the Lease Commencement Date shall not be extended for any delay
in Substantial Completion to the extent that such delay is caused in whole or in
part by any act or omission attributable to Tenant, including without
limitation:

         (a) Tenant's request for any Leasehold Improvements which require
         materials which need to be ordered and are not immediately available;

         (b) Tenant's failure to furnish promptly information concerning
         Tenant's requirements pertaining to construction of the Leasehold
         Improvements or any other information requested by the Landlord as
         necessary or useful to prepare the Construction Documents;

         (c) Tenant's failure to approve promptly the Construction Documents and
         Final Cost; and

         (d) Tenant's request for any changes in the Leasehold Improvements from
         the work as reflected in the Construction Documents.

         Landlord agrees to use its best efforts to substantially complete the
Leasehold Improvements so as to permit Tenant to occupy the Leased Premises on
or before March 31, 1998.

         4.02 In any event, Rent payable under the Lease shall not abate by
reason of any delay, expense or other burden arising out of or incurred in
connection with the design or construction of the Leasehold Improvements to the
extent that such delay, expense or other burden is caused
<PAGE>   30
in whole or in part by any act or omission attributable to Tenant (including,
without limitation, the acts and omissions referred to in subparagraphs (a)
through (d) of paragraph 4.01 above).

         5. Tenant's Access To Leased Premises

agents or independent contractors to enter the Leased Premises prior to the
scheduled Lease Commencement Date in order that Tenant may do other work as may
be required by Tenant to make the Leased Premises ready for Tenant's use and
occupancy; provided, however, subject to the coordination of its activities with
Landlord and provided such activities do not materially interfere with
Landlord's work to be performed hereunder, Landlord agrees that Tenant (and its
representatives or contractors) shall be permitted access to the Leased Premises
while the walls and interior partitions are exposed to install any cable, wire
or conduit. Such permission must be in writing prior to entry. If Landlord
permits such prior entry, then such license shall be subject to the condition
that Tenant and Tenant's agents, contractors, workmen, mechanics, suppliers, and
invitees shall work in harmony with and not interfere with Landlord and its
agents and contractors in doing its work in the Leased Premises or the Building
or with other tenants and occupants of the Building or the Project. If at any
time such entry shall cause or threaten to cause disharmony or interference,
Landlord, in its sole discretion, shall have the right to withdraw and cancel
such license upon notice to Tenant. Tenant agrees that any such entry into the
Leased Premises shall be deemed to be under ail of the terms, covenants,
conditions and provisions of the Lease, except as to the covenant to pay
periodic Rent. Tenant further agrees that, to the extent permitted by law and
consistent with the terms of this Lease, Landlord and its principals shall not
be liable in any way for any injury or death to any person or persons, loss or
damage to any of the Leasehold Improvements or installations made in the Leased
Premises or loss or damage to property placed therein or there about, the same
being at Tenant's sole risk.

         5.02 In addition to any other conditions or limitations on such license
to enter the Leased Premises prior to the Lease Commencement Date, Tenant
expressly agrees that none of its agents, contractors, workmen, mechanics,
suppliers or invitees shall enter the Leased Premises prior to the Lease
Commencement Date unless and until each of them shall furnish Landlord with
satisfactory evidence of insurance coverage, financial responsibility and
appropriate written releases of mechanics' or materialmen's lien claims.

         6. Miscellaneous Provisions Landlord and Tenant further agree as
follows:

         6.01 Except as herein expressly set forth with respect to the Leasehold
Improvements, Landlord has no agreement with Tenant and has no obligation to do
any work with respect to the Leased Premises. Any other work in the Leased
Premises which may be permitted by Landlord pursuant to the terms and conditions
of the Lease shall be done at Tenant's sole cost and expense and in accordance
with the terms and conditions of the Lease.

         6.02 This Schedule shall not be deemed applicable to: (a) any
additional space added to the original Leased Premises at any time, whether by
the exercise of any options under the

additions thereto in the event of a renewal or extension of the original Lease
Term, whether by the exercise of any options under the Lease or any amendment or
supplement thereto. The construction of any additions or improvements to the
Leased Premises not contemplated by this Schedule shall be effected pursuant to
a separate work letter agreement or other document, in the form then being used
by Landlord and specifically address the allocation of costs relating to such
construction.

ADDITIONAL PROVISIONS

2. Option to Renew

Tenant shall have one option to renew ("Option to Renew") this Lease for five
(5) years (the "Renewal Period"). If Tenant desires to exercise its Option to
Renew, Tenant shall give Landlord written notice ("Renewal Notice") thereof on
or before *. During the thirty (30) day period following Landlord's receipt of
the Renewal Notice, Landlord and Tenant shall use reasonable efforts to
negotiate a mutually agreeable base rent ("Market Base Rent") for the Renewal
Period. The Market Base Rent shall be negotiated in light of then current terms
for renewing tenants for comparable space, including market rents, term of
renewal, and operating expense pass throughs. Within fifteen (15) business days
of agreement by the parties on the Market Base Rent and other terms of the
renewal, Landlord shall deliver to Tenant an amendment to this Lease extending
this Lease on such terms. Such amendment shall not contain any further option to
renew. Tenant shall execute and deliver the amendment to Landlord within ten
(10) business days following receipt of such amendment. The foregoing option and
rights are subject to there existing no Event of Default of which Tenant has
been notified and no prior Event of default which Tenant failed to cure within
any applicable cure period, are personal to the original Tenant executing the
Lease, may not be assigned; provided, however such right to extend the term of
this Lease may also be exercised by any parent, affiliate or subsidiary of
Tenant or any entity acquiring Tenant, to which the Lease may be assigned
pursuant to Section 6.04. Time is of the essence in the exercise of Tenant's
Option to Renew. Should Tenant fail to exercise such option, execute and deliver
any required documents, or perform any of its required obligations under this
section, or should the parties be unable to agree on Market Base Rent for the
Renewal Period, within the time periods set forth above, then this Option to
Renew and any other rights of Tenant under the Lease in the nature of options,
shall be null and void, and the Lease shall terminate at the end of the Lease
Term.

*(9) months prior to the expiration of the initial lease term.

ADDITIONAL PROVISIONS

3. Right of First Opportunity

Provided no Event of Default then exists, Tenant will have the right of first
opportunity ("Right of First Opportunity") to lease space that becomes available
on the fourth (4th) floor of the Building. Landlord shall notify Tenant in
writing when said space becomes available. Tenant will then have ten (10)
business days to respond in writing of Tenant's intent to exercise this Right of
First Opportunity. If Tenant fails to respond in said (10) day period, then
Tenant will have waived this Right of First Opportunity for said space. Upon
Landlord's receipt of Tenant's written acknowledgment to exercise said Right of
First Opportunity, Landlord shall have ten (10) days to provide Tenant with the
terms and conditions under which the Landlord would propose
<PAGE>   34
to lease the space to Tenant, which terms and condition shall reflect what
Landlord reasonably believes to be a market proposal for such space. Landlord
and Tenant shall then have thirty (30) days to negotiate and agree to the terms
and conditions. If Landlord and Tenant have not agreed to terms and conditions
during said thirty (30) day period, then Landlord shall be allowed to lease said
space to a third party.

ADDITIONAL PROVISIONS

4. Option to Terminate

Tenant shall have a one time right to terminate the Lease on *1 ("Early
Termination Date"). In order to exercise such option, Tenant shall give Landlord
prior written notice ("Termination Notice") on *2 of its election to terminate
this Lease. The Termination Notice shall be valid only if accompanied by a
cashier's check in an amount equal to $*3 ("Termination Fee"). If all of the
foregoing conditions are timely satisfied by Tenant, this Lease shall terminate
on the Early Termination Date as if such date were the Lease Expiration Date.
The foregoing option and rights are subject to there existing no Event of
Default of which Tenant has been notified and no prior Event of Default which
Tenant failed to cure within any applicable cure period, are personal to the
original Tenant executing the Lease, may not be assigned; provided, however,
such right to terminate may also be exercised by any parent, affiliate or
subsidiary of Tenant, or any entity acquiring Tenant, to which this Lease may
have been assigned. Time is of the essence in the exercise of Tenant's Option to
Terminate. Should Tenant fail to exercise such option and deliver notice thereof
to Landlord, or fail to perform any of its required obligations under this
section within the time periods set forth above (including, without limitation,
paying the Termination Fee at the same time as the Termination Notice), then
this Option to Expand shall terminate and be null and void. Within ten (10) days
of Tenant's receipt of an invoice for same, Tenant shall promptly pay to
Landlord the unamortized amount (factored with a ten percent annual interest
rate) of the Allowance utilized by Tenant in the construction of the Leasehold
Improvements and any brokerage fees and commissions paid by Landlord in
conjunction with this Lease.

                                       I.

                 1.1     LEASED PREMISES.  Subject to and upon the terms,
provisions and conditions hereinafter set forth, and each in consideration of
the duties, covenants and obligations of the other hereunder, Landlord does

being more particularly described as follows:

         containing approximately four thousand five hundred and thirty five

(i) in the case of a single tenancy floor, all floor area measured from the
inside surface of the outer glass or finished column wall of the Building to
the inside surface of the opposite outer wall excluding only the areas
("Service Areas") within the outside walls used for building stairs, fire
towers, elevator shafts, flues, vents, stacks, pipe shafts and vertical ducts,

of the Building's elevator and main mechanical and electrical rooms, management
office, other areas necessary to provide customary services to the Building and
public lobbies, and (ii) in the case of a floor to be occupied by more than one
tenant, all floor areas within the inside surface of the outer glass or

tenants or from areas devoted to corridors, elevator foyers, rest rooms,
mechanical rooms, janitor closets, vending areas and other similar facilities

necessary to the Building.  The Net Rentable Area in the Leased Premises has
been calculated on the basis of the foregoing definition and is hereby
stipulated for all purposes hereof to be four thousand five hundred and thirty
five (4,535)  square feet, whether the same should be more or less as a result
of minor variations resulting from actual construction and completion of the
Leased Premises for occupancy so long as such work is done in accordance with
the terms and provisions hereof.

attached hereto and made a part hereof as Exhibit B.

herein, and in each exhibit or addendum hereto, this Lease shall continue in

                 (b)     In the event the Leased Premises should not be ready
for occupancy by the Commencement Date stated in Section 2.1(a) above, or in
the event the Commencement Date is delayed as a result of Landlord's acts or
otherwise, Landlord shall not be liable or responsible for any claims, damages
or liabilities in connection therewith or by reason thereof.  As Tenant's sole
and exclusive remedy for any such delay, the term of this Lease shall not
commence until the Commencement Date occurs, and the rent provided for herein
shall not commence to be payable until the Commencement Date.  At the request
of either party, a declaration of lease commencement in form and substance
reasonably acceptable to the parties will be executed specifying the
Commencement Date established above.

                 (c)      This Lease shall survive the termination of any
underlying lease, provided such underlying landlord recognizes this Lease.

                 2.2     USE.  The Leased Premises shall be used and occupied
by Tenant (and its permitted assignees and subtenants) solely as general,
administrative and executive offices (including such ancillary uses in
connection therewith as shall be reasonably required by Tenant in the operation
of its business); provided, that in no event shall any of the following be
permitted in the Leased Premises: (i) offices or agencies of a foreign
government or political subdivision thereof; (ii) offices of any governmental
bureau or agency of the United States or any state or political subdivision
thereof; (iii) personnel agencies; or (iv) customer service offices of any
public utility company.  The following uses shall not be permitted in the
Leased Premises except to the extent they are ancillary to an otherwise
permitted use: (v) data processing activities; (vi) health care activities;
(vii) schools or other training or educational uses; (viii) clerical support
services; (ix) reservation centers for airlines or travel agencies; (x) retail
or restaurant use; (xi) studios for radio, television or other media; or (xii)
storage.  The Leased Premises shall not be used for any purpose which would, in
Landlord's reasonable opinion, lower the first-class character of the Building
or any part thereof, create unreasonable or excessive elevator or floor loads,
interfere with any of the operations of the Building or any part thereof or the
proper and economic heating, air-conditioning, cleaning or other servicing of
the Building or any part thereof or unreasonably interfere with the use of the
other areas of the Building by any other tenants.

                 2.3     BASE RENTAL.  Tenant hereby agrees to pay annual base
rental ("Base Rental") without deduction, offset or counterclaim in an amount
equal to the product of $19.56  per square foot of Net Rentable Area multiplied
by the Net Rentable Area of the Leased Premises, plus a management fee of 3% of
Tenant's Base Rental and Additional Rental.  Base Rental shall be due and
payable, without notice or demand, in twelve (12) equal installments on the
first day of each calendar month during the Term, and any renewals or
extensions thereof at Landlord's address as provided herein (or such other
address as may be designated by Landlord from time to time).  If the Term
commences on other than the first day of a month or terminates on other than
the last day of a month, then the installments of Base Rental for such month or
months shall be prorated and the installment or installments so prorated shall
be paid in advance.  All past due installments of rent shall





                                      -3-
<PAGE>   8
bear interest until paid at the lesser of (i) eighteen percent (18%) per annum
or (ii) the maximum lawful contract rate permitted by applicable law (the
"Maximum Rate").

                 2.4     TENANT'S PROPORTIONATE SHARE OF BASIC COSTS.

                 (a)     There is established under this Lease a "Base Year",
which for these purposes is the calendar year 1996.  In the event that the
Basic Costs (as hereinafter defined) of Landlord's ownership, maintenance and
operation of the Project during the first calendar year after the Base Year
shall differ from the Basic Costs of Landlord therefor during the Base Year,
Tenant shall pay its proportionate share of the year's increases in the Basic
Costs for such year in the proportion its Net Rentable Area bears to the
greater of 95% of the total Net Rentable Area of the Building leased or held
for lease for office and/or retail use or to the total Net Rentable Area in the
Building actually leased for office and/or retail use ("Tenant's Proportionate
Share").  If Tenant's Proportionate Share of any increase or projected increase
in Basic Costs is payable by Tenant for any partial calendar year, then such
amount shall be prorated for such partial calendar year of commencement,
expiration or termination so that Tenant pays an amount equal to Tenant's
Proportionate Share of the amount by which the Basic Costs exceed the Base
Year's Basic Costs, multiplied by a fraction, the numerator of which is the
number of days in such calendar year for which Tenant is obligated to pay
Tenant's Proportionate Share of any increase in Basic Costs in such calendar
year and the denominator is 365.

                 (b)     For each calendar year during the Term following the
Base Year, Landlord shall provide Tenant a comparison of the Base Year's Basic
Costs and the projected Basic Costs for such year prior to January 1 of such
year, and Tenant shall thereafter pay Landlord an amount estimated by Landlord
for such year as Tenant's Proportionate Share of any projected increase in
Landlord's Basic Costs for the Project for such year over Base Year's Basic
Costs.  The estimated amount of Tenant's Proportionate Share of any projected
increases in Basic Costs shall be due without notice, demand, deduction, offset
or counterclaim, and payable at the same place as Base Rental in twelve (12)
equal monthly installments on the first day of each calendar month during such
year.  Landlord shall within the period of one hundred fifty (150) days (or as
soon thereafter as possible), after the close of each calendar year following
the first calendar year, provide Tenant a statement of such year's actual Basic
Costs showing the actual increase in Landlord's Basic Costs of operating the
Project from the Base Year.  If the actual increase is greater than that
projected, Tenant shall pay Landlord, within thirty (30) days of Tenant's
receipt of such statement, Tenant's Proportionate Share of the difference.  If
such year's projected Basic Costs are greater than the actual Basic Costs,
Landlord shall pay Tenant, within thirty (30) days of said statement's
issuance, Tenant's Proportionate Share of the difference; provided, however,
the rental owed by Tenant shall never be less than the Base Rental stated in
Section 2.3.

                 (c)     "Basic Costs" as said term is used herein shall
consist of all operating expenses of the Project, and such additional
facilities in subsequent years as may be determined by Landlord to be
necessary.  All operating expenses shall be computed on an accrual basis and
determined in accordance with generally accepted accounting principles which
shall be consistently applied.  The





                                      -4-
<PAGE>   9
term "operating expenses" as used herein shall mean all expenses, costs and
disbursements (but not replacement of capital investment items (other than
those described in subparagraph 9 below) nor specific costs especially billed
to and paid by specific tenants) of every kind and nature which Landlord shall
pay or become obligated to pay because of or in connection with the ownership,
maintenance and operation of the Project, including, but not limited to, the
following:

                         (1)      Wages, salaries, benefits and related
expenses of all on-site employees and the allocable pro rata cost of such
expenses attributable to off-site personnel providing services to the Project
engaged in the operation, maintenance or access control of the Project and
personnel who may provide traffic control relating to ingress and egress to and
from the Project.  All taxes, insurance and benefits relating to employees
providing these services shall be included.

                         (2)      All costs and expenses of operating the
management administrative office for the Project.

                         (3)      All supplies, tools, equipment, and materials
used in operation and maintenance of the Project.

                         (4)      Cost of all utilities for the Project
including the cost of water and power, heating, lighting, air conditioning and
ventilating for the Project and the cost of operating any central plant that
may serve the Building.

                         (5)      Cost of all maintenance and service
agreements for the Project and the equipment therein, including, but not
limited to, access control service, window cleaning, elevator maintenance,
cleaning and restriping.

                         (6)      Cost of all insurance relating to the Project
including, but not limited to, the cost of casualty and liability insurance
applicable to the Project and Landlord's personal property used in connection
therewith.

                         (7)      All taxes and assessments and governmental
charges whether federal, state, county or municipal, and whether they be by
taxing districts or authorities presently taxing the Leased Premises or by
others, subsequently created or otherwise, and any other taxes and assessments
attributable to the Project or its operation.  It is agreed that Tenant will be
responsible for ad valorem taxes on its personal property and on the value of
Leasehold improvements to the extent that same exceed standard building
allowances.

                         (8)      Cost of repairs and general maintenance
(excluding repairs and general maintenance paid by proceeds of insurance or by
Tenant or other third parties, and alterations attributable solely to tenants
of the Building other than Tenant).





                                      -5-
<PAGE>   10
                         (9)      Amortization (including a reasonable interest
charge) of the cost of installation of capital investment items which are
primarily for the purpose of reducing operating costs or which may be required
by governmental authority.  All such costs shall be amortized over the
reasonable life of the capital investment items and added to Basic Costs, with
the reasonable life and amortization schedule being determined in accordance
with generally accepted accounting principles and in no event to extend beyond
the reasonable life of the Building.  In the case of installations for the
purpose of reducing operating costs, Landlord shall have a cost justification
for its practicality.

                         (10)     Landlord's central accounting and audit costs
applicable to the Project including the cost of audits by certified public
accountants.

                         (11)     The Building's share of all expenses related
to the operation, ownership and maintenance of the Town Center, including, but
not limited to, ad valorem property taxes, property owner association
assessments and the cost of maintaining and operating the common facilities of
the Town Center.

                 Notwithstanding any other provision herein to the contrary, it
is agreed that in the event the Building is not fully occupied or provided with
Building Standard services during the Base Year or any subsequent year, the
Basic Costs shall be computed for such year as though the Building had been
fully occupied and had been provided with Building Standard services during
such year.

                 Anything in the foregoing provisions hereof to the contrary
notwithstanding, Operating Expenses shall not include the following:

                         (A)      Costs of repairs, restoration, replacements
or other work occasioned by (1) fire, windstorm or other casualty of an
insurable nature (whether such destruction be total or partial) and paid by

governmental authority of the right of eminent domain, whether such taking be
partial or total, and (3) the gross negligence or willful misconduct of
Landlord, or its agents and employees.

                         (B)      Leasing commissions, attorneys' fees, costs,
disbursements and other expenses incurred in connection with negotiations for

Project.

                         (C)      Allowances and other costs and expenses
(including permit, license and inspection fees) incurred in fixturing,
furnishing, renovating or otherwise improving, decorating or redecorating space

                         (D)      The cost of all items, goods and services for
which Tenant, any other tenant or occupant of the Project or other third party
(including insurers) reimburses Landlord or for





                                      -6-
<PAGE>   11
which Landlord is entitled to reimbursement to the extent of such entitlement
(other than through the payment of a tenant's share of Operating Expenses of
the Project).

                         (E)      Costs which are to be capitalized in
accordance with generally accepted accounting principles not included under
subsection (9) above.

                         (F)      Costs or expenses for services of a type or
quantity which Tenant is not entitled to receive (and does not receive) but
which are provided to another tenant or occupant of the Project.

finance charges made on any debt (except as provided in subsection (9) above),
and rental payments made under any ground or underlying lease or leases, except
to the extent that a portion of such payments is expressly for ad valorem/real
estate taxes or insurance premiums on the Project.

                         (I)      Landlord's general corporate overhead
relating solely to the internal organization and function of Landlord as a

(as opposed to the maintenance, ownership and operation of the Project).

                         (J)      Any compensation paid to clerks, attendants
or other persons employed in commercial concessions operated by Landlord for a

as set forth in Sections 2.4 (a) and (b) herein, without notice,





                                      -7-
<PAGE>   12
demand, offset or counterclaim, and all such amounts shall constitute
additional rental ("Additional Rental") owed by Tenant to Landlord.  Landlord
shall have the same remedies for default in the payment of Additional Rental as
are available to Landlord in the event of a default in the payment of Base
Rental.

                          Tenant, at its expense, shall have the right at all
reasonable times to audit Landlord's books and records relating to this Lease

an independent auditor as defined by generally accepted auditing standards.
Further, Tenant may exercise such audit rights for any calendar year only if
Tenant notifies Landlord of Tenant's intent to audit within ninety (90) days

statement described in Section 2.4(b), and Tenant's audit rights shall in all
events expire as to any calendar year on December 31 of the calendar year
following such calendar year.

                 2.6     SECURITY DEPOSIT.

                 (a)     Tenant shall pay to Landlord on the date this Lease is
executed by Tenant a security deposit equal to one (1) month of the Base Rental
due during the first twelve (12) months of the Term (without regard to any rent
concessions or holidays granted to Tenant by Landlord) and such other security
as Landlord may require.  Upon the occurrence of any default by Tenant,
Landlord may, from time to time, without prejudice to any other remedy, use the
security deposit to the extent necessary to make good any arrears of rent, or
to pay any sums owed to Landlord under this Lease, or any damage, injury,
expense or liability caused to Landlord by such default.  The security deposit
shall not be considered an advance payment of rent or a measure of Landlord's
damages in case of default by Tenant.  Tenant shall not be entitled to receive
any interest on the security deposit, and Landlord may commingle the same with
other monies of Landlord.  If Landlord shall from time to time apply the
security deposit to pay the sums described above, and if this Lease has not
been terminated, Tenant shall immediately deposit with Landlord an additional
security deposit equal to the amount so used.  Tenant shall not assign or
encumber the security deposit in any manner, and Landlord shall not be bound by
any such assignment or encumbrance.

                  (b)    If Tenant shall fully and faithfully comply with all
of the terms, provisions, covenants and conditions of this Lease, then the
security deposit shall be returned to Tenant (without regard to any assignment
or encumbrance of the same) within thirty (30) days after:

                          (i)     the termination of this Lease (provided such
termination is not the result of a default by Tenant),





                                      -8-
<PAGE>   13
                          (ii)    delivery of possession of the Leased Premises
                                  to Landlord in accordance with the provisions
                                  of Section 4.4, and

                          (iii)   payment of all sums due to Landlord
                                  hereunder. 
                                   

Upon sale or lease of the Building, Landlord shall transfer the security
deposit to the vendee or Tenant and Landlord shall be released by Tenant upon
said transfer from all liability for the return of such security deposit and
Tenant agrees to look solely to the new landlord for the return of the security
deposit.  It is agreed that the provisions hereof shall apply to every transfer
or assignment made of the security deposit to a new landlord.


                                      III.

                      SERVICES TO BE FURNISHED BY LANDLORD

                 Landlord covenants and agrees with Tenant:

                 3.1     SERVICES.  Landlord shall use reasonable efforts to
furnish (as part of the Basic Costs of the Project) Tenant while occupying the
Leased Premises:

                 (a)     Hot and cold water at those points of supply provided
for general use of other tenants in the Building; central heat and air
conditioning as provided in Exhibit F attached hereto; routine maintenance and
electric lighting service for all public areas and special service areas of the
Building in the manner and to the extent deemed by Landlord to be standard.

                 (b)     Janitor service on a five (5)-day week basis at no
extra charge; provided, however, if Tenant's floor covering or other
improvements is other than Building Standard (as defined in Exhibit E attached
hereto), Tenant shall pay as Additional Rental the additional cleaning cost
attributable thereto, plus fifteen percent (15%) to cover overhead.  Tenant
shall pay said Additional Rental upon presentation of a statement therefor by
Landlord, and Tenant's failure to pay shall constitute default hereunder after
Tenant's failure to pay within ten (10) days.

                 (c)     Sufficient electrical capacity distributed to a panel
box located at the core of each floor of the Leased Premises to operate (A)
typewriters, voice writers, calculating machines and other machines of similar
low electrical consumption (120/208 volts) to the extent that the total design
load of low electrical voltage within the Leased Premises does not to exceed
two (2) watts per square foot of usable area, and (B) lighting and equipment of
standard high voltage electrical consumption (277/480 volt) to the extent that
the total design load of high electrical voltage within the Leased Premises
does not exceed two (2) watts per square of usable area.  If the installation
of said electrical equipment requires additional air conditioning capacity
above that provided by the





                                      -9-
<PAGE>   14
Building Standard system, then the additional air conditioning installation and
operating costs, plus fifteen percent (15%) to cover overhead, will be the
obligation of Tenant.

                 (d)     All Building Standard fluorescent bulb replacement in
all areas and all incandescent bulb replacement in public areas, toilet and
rest room areas and stairwells.

                 (e)     Access control to the Building during weekends and
after normal working hours during the week so as to provide Tenant with seven
day and twenty-four hour access to the Leased Premises; PROVIDED, HOWEVER, THAT
LANDLORD SHALL NOT BE LIABLE TO TENANT, ITS AGENTS, CONTRACTORS, CUSTOMERS,
EMPLOYEES, INVITEES, LICENSEES, SERVANTS OR VISITORS FOR ANY DAMAGES, LOSSES,
CLAIMS, OR CAUSES OF ACTION, ARISING OUT OF OR IN CONNECTION WITH PERSONAL
INJURY OR PROPERTY DAMAGE CAUSED BY OR DUE TO THEFT, BURGLARY OR PERSONS
GAINING ACCESS TO THE BUILDING, THE PROJECT OR THE LEASED PREMISES, EVEN IF
CAUSED BY THE NEGLIGENCE OF LANDLORD.

                 Failure by Landlord to any extent to furnish any services to
Tenant, the Leased Premises or the Project, or any cessation thereof, shall not
render Landlord liable in any respect for damages to person, property or
otherwise, nor be construed as an eviction of Tenant, nor work an abatement of
rent (except as expressly provided in this paragraph), nor relieve Tenant from
fulfillment of any covenant or agreement hereof; provided, however, that should
Landlord cease to furnish any of the aforementioned services or such services
are interrupted for reasons other than (i) curtailment in services imposed by
any governmental authority, (ii) failure of the public utilities to furnish
necessary services, or (iii) Tenant's negligence, gross negligence or willful
misconduct (a "Service Interruption"), and if, as a result of such Service
Interruption, the Leased Premises (or any part thereof) is untenantable such
that Tenant must vacate that portion of the Leased Premises affected and such
Service Interruption continues for a period of three (3) or more consecutive
Business Days (as defined below) after Landlord's receipt of written notice
from Tenant of such Service Interruption, then all rent including, without
limitation, Base Rental shall abate as to those portions of the Leased Premises
rendered untenantable, which abatement shall commence on the fourth (4th)
consecutive Business Day after Landlord's receipt of written notice from Tenant
of such Service Interruption and shall continue until such space is again
tenantable.  The foregoing rental abatement rights shall constitute Tenant's
sole and exclusive remedies involving or with respect to a Service
Interruption.  Notwithstanding the foregoing, if a Service Interruption occurs
as a result of or in connection with a fire or other casualty or a taking or
condemnation for  a public purpose (or a conveyance in lieu thereof), the
foregoing rental abatement rights shall not be available to Tenant, and
Tenant's and Landlord's rights and obligations with respect thereto shall be
governed by Section 5.1 of this Lease in the case of a taking or condemnation
(or a conveyance in lieu thereof) or by Section 5.6 of this Lease in the case
of a fire or other casualty.  Should any of the equipment or machinery utilized
in supplying the services listed herein break down, or for any cause cease to
function properly, Landlord shall use due diligence to repair same promptly.





                                      -10-
<PAGE>   15
                 3.2     KEYS AND LOCKS.  Landlord shall, at Landlord's
expense, furnish Tenant two (2) keys each for no more than two (2) corridor
doors entering the Leased Premises.  Additional keys will be furnished at a
charge by Landlord on an order signed by Tenant or Tenant's authorized
representative.  All such keys shall remain the property of Landlord.  No
additional locks shall be allowed on any door of the Leased Premises without
Landlord's permission, and Tenant shall not make, nor permit to be made, any
duplicate keys, except those furnished by Landlord.  Upon termination of this
Lease, Tenant shall surrender to Landlord all keys of the Leased Premises, and
give to Landlord the explanation of the combination of all locks for safes,
safe cabinets and vault doors, if any, remaining in the Leased Premises.

                 3.3     GRAPHICS.  Landlord shall provide and install, at
Tenant's cost, all letters or numerals at Tenant's primary entrance door to the
Leased Premises; all such letters and numerals shall be in the Building
Standard graphics, and no others shall be used or permitted on the Leased
Premises.  Landlord also agrees to provide and install, at Tenant's expense, a
listing on the Building directory board.  All costs and expenses shall be
reasonable and agreed upon by the parties.

                 3.4     IMPROVEMENTS TO BE MADE BY LANDLORD.  All
installations now or hereafter placed on the Leased Premises in excess of
Building Standard items shall be for Tenant's account and at Tenant's cost (and
Tenant shall pay ad valorem taxes and increased insurance thereon), which cost
shall be payable by Tenant to Landlord as Additional Rental hereunder promptly
upon being invoiced therefor provided all costs were preapproved by Tenant and
all installations properly made in accordance with all laws, and failure by
Tenant to pay same in full within thirty (30) days shall constitute an Event of
Default by Tenant hereunder and a breach of this Lease by Tenant giving rise to
all remedies available to Landlord under this Lease and at law for nonpayment
of rent.

                 3.5     PEACEFUL ENJOYMENT.  That Tenant shall, and may
peacefully have, hold and enjoy the Leased Premises, subject to the other terms
hereof, provided that Tenant pays the rental and other sums herein recited to
be paid by Tenant and performs all of Tenant's covenants and agreements herein
contained.  It is understood and agreed that this covenant and any and all
other covenants of Landlord contained in the Lease shall be binding upon
Landlord and its successors only with respect to breaches occurring during its
and their respective ownerships of the Landlord's interest hereunder.

                 3.6     LIMITATION OF LANDLORD'S PERSONAL LIABILITY.  It is
understood and agreed by Landlord and Tenant that any and all covenants of
Landlord contained in this Lease shall be binding upon Landlord and its
successors only with respect to breaches occurring during the period of
Landlord's and its successor's respective ownership of the Landlord's interest
hereunder.  Tenant specifically agrees to look solely to Landlord's interest in
the Building for the recovery of any judgment from Landlord, it being agreed by
Landlord and Tenant that Landlord's (or its successor's) partners,
shareholders, officers, directors and employees shall never be personally
liable for any such judgment. The provision contained in the foregoing sentence
is not intended to, and shall not, limit any right that Tenant might otherwise
have to obtain injunctive relief against





                                      -11-

Landlord or Landlord's successors in interest, or any other action not
involving the personal liability of Landlord.  LANDLORD'S DUTIES AND WARRANTIES
ARE LIMITED TO THOSE EXPRESSLY STATED IN THIS LEASE AND SHALL NOT INCLUDE ANY
IMPLIED DUTIES OR IMPLIED WARRANTIES, NOW OR IN THE FUTURE.  NO REPRESENTATIONS
OR WARRANTIES HAVE BEEN MADE BY LANDLORD OTHER THAN THOSE CONTAINED IN THIS
LEASE.

                 3.7     PARKING.  Parking shall be provided as set forth in
Exhibit C attached hereto and made a part hereof.

                                      IV.

                 Tenant covenants and agrees with Landlord:

                 4.1     PAYMENTS BY TENANT.  Tenant shall pay all rent and
sums provided to be paid to Landlord hereunder at the times and in the manner
herein provided.

                 4.2     REPAIRS BY LANDLORD.  Unless otherwise stipulated
herein, Landlord shall not be required to make any improvements to or repairs
of any kind or character on the Leased Premises during the Term, except such
repairs as may be deemed necessary by Landlord for normal maintenance
operations.  The obligation of Landlord to maintain and repair the Common Areas
and the Leased Premises in good order and repair, including replacements, shall
be limited to Building Standard items, improvements, the exterior and
structural portions of the Building and those areas for which a tenant is not
responsible for the maintenance, repair or replacement of same.  Non-Building
Standard items improvements will, at Tenant's written request, be maintained by
Landlord at Tenant's expense, at a cost or charge equal to the costs incurred
in such maintenance plus an additional charge of fifteen percent (15%) to cover
overhead.

                 4.3     REPAIRS BY TENANT.  Tenant shall, at its own cost and
expense, to repair or replace any damage or injury done to the Project, or any
part thereof, caused by Tenant or Tenant's agents, employees, invitees, or
visitors and which are not covered by any casualty insurance maintained or
required to be maintained by Landlord hereunder; provided, however, if Tenant
fails to make such repairs or replacement promptly after receipt of written
notice to cure, Landlord may, at its option, make repairs or replacements, and
Tenant shall repay the cost thereof, plus fifteen percent (15%) to cover
overhead, to the Landlord on demand, subject to Section 5.15.

                 4.4     CARE OF THE LEASED PREMISES.  Tenant shall not commit,
or allow to be committed, any waste or damage on any portion of the Leased
Premises, and at the termination of this Lease, by lapse of time or otherwise,
to deliver up said Leased Premises to Landlord in as good condition as at date
of possession by Tenant, ordinary wear and tear excepted, and upon such
termination of this Lease, Landlord shall have the right to re-enter and resume
possession of the Leased Premises.

                 4.5     ASSIGNMENT OR SUBLEASE.  In the event Tenant should
desire to assign this Lease or sublet the Leased Premises or any part thereof,
Tenant shall give Landlord written notice of such desire at least sixty (60)
days in advance of the date on which Tenant desires to make such assignment or
sublease.  Landlord shall then have a period of thirty (30) days following
receipt of such notice within which to notify Tenant in writing that Landlord
elects either (1) to terminate this Lease as to the space so affected as of the
date so specified by Tenant in which event Tenant will be relieved of all
further obligations under this Lease as to such space which occur after the
date of such termination, or (2) to permit Tenant to assign this Lease or
sublet such space, subject, however, to (i) written approval of the proposed
assignee or subtenant by Landlord and (ii) the requirement that Tenant enter
into written agreements with Landlord, and with assignee or subtenant, that any
profit realized by Tenant as a result of such assignment or sublease with
respect to the use and occupancy of the Leased Premises (meaning, in the case
of an assignment, the consideration agreed upon between Tenant and assignee or,
in the case of a sublease, the difference between the rental rate agreed upon
between Tenant and subtenant and the rent then required to be paid under this
Lease multiplied by the number of months in the term of the sublease) shall, to
the extent such profit is immediate, be due and payable by Tenant to Landlord
upon the execution of an assignment or sublease, and, to the extent such profit
is deferred, be payable to Landlord by assignee or subtenant as it accrues, or
(3) to refuse to consent to Tenant's assignment of this Lease or sublease of
such space and to continue this Lease in full force and effect as to the entire
Leased Premises.  If Landlord should fail to notify Tenant in writing of such
election within the stated thirty (30) day period, Landlord shall be deemed to
have elected option (3) above.  No consent by Landlord to any assignment or
sublease shall be deemed to be consent to a use not permitted under this Lease,
to any act in violation of this Lease, or to any other or subsequent assignment
or sublease, and no assignment or sublease by Tenant shall relieve Tenant of
any obligation under this Lease.  Any sublease or assignment shall be subject
to all the terms and conditions of this Lease.  Any attempted assignment or
sublease by Tenant in violation of the terms and covenants of this paragraph
shall be void.

                 Notwithstanding anything to the contrary contained in this
Section 4.5, the consent of Landlord need not be obtained for (i) any
assignment or subletting to an Affiliate (defined below) of Tenant, (ii) any
assignment of this Lease made in connection with the merger or consolidation of
Tenant with or into any other corporation or entity, and (iii) an assignment of
this Lease made in connection with a sale or transfer of a majority of the
assets and liabilities of Tenant, so long as, with respect to clauses (i), (ii)
and (iii), (1) the assignee or sublessee shall be engaged in the same field of
services as Tenant, (2) the assignee or sublessee is engaged in a business
customarily acceptable for a tenant in a first class high-rise office building
in Town Center, (3) any assignee shall assume all of the obligations of Tenant
under this Lease, (4) at the time of such assignment or subletting, this Lease
is in full force and effect and there is no breach under this Lease on the part
of Tenant, (5) the assignee's or sublessee's proposed use of the Leased
Premises is not in violation of this Lease, and (6) any assignee's
shareholders' equity or net worth, as applicable, is equal to or greater than
Tenant's shareholders' equity or net worth, as applicable, as of the
Commencement Date (determined in accordance with generally accepted accounting
principles) (such assignee or sublessee in clause





                                      -13-
<PAGE>   18
(i), (ii) and (iii) complying with clauses (1), (2), (3), (4), (5) and (6),
hereinafter a "Permitted Affiliate").  At least ten (10) days prior to the
effective date of any such assignment or sublease to a Permitted Affiliate,
Tenant agrees to furnish Landlord with notice of such assignment or sublease
and copies of the instruments effecting any such assignment or sublease.
Additionally, within thirty (30) days after the effective date of any such
assignment or sublease to a Permitted Affiliate, Tenant agrees to furnish
Landlord with copies of the fully executed instruments effecting any such
assignment or sublease and documentation establishing Tenant's satisfaction of
the requirements set forth above applicable to any such sublease or assignment.
Any such assignee of Tenant must assume and agree in writing to fully perform
and observe all of the obligations and agreements of Tenant under this Lease
and any such sublessee shall sublease such portion of the Leased Premises
subject to the provisions of this Lease.  No such assignment or subletting
shall relieve Tenant, any other tenant, or any guarantor of this Lease of any
covenants or obligations under this Lease or any such guaranty and Tenant, any
other tenant, and any guarantors of this Lease shall remain fully liable
hereunder and thereunder.  Notwithstanding anything to the contrary set forth
in this Lease, the rights granted to Tenant under this paragraph of subsection
(a) as to assignments and subleases to Permitted Affiliates shall not be
assignable by Tenant, shall inure only to the benefit of Tenant and shall not
be enforceable by any assignee or sublessee of Tenant.

                 As used herein, "Affiliate" shall mean any person or entity
controlling, controlled by, or under common control with, another person or
entity.  "Control" as used herein means the possession, direct or indirect, of
the power to direct or cause the direction of the management and policies of
such controlled person or entity (the ownership, directly or indirectly, of at
least fifty-one percent (51%) of the voting securities of, or possession of the
right to vote, in the ordinary direction of its affairs, at least fifty-one
percent (51%) of the voting interest in, any person or entity shall be presumed
to constitute such control).

                 4.6     ALTERATIONS, ADDITIONS, IMPROVEMENTS.  Tenant shall
not permit the Leased Premises to be used for any purpose other than that
stated in the use clause hereof, or make or allow to be made any alterations or
physical additions in or to the Leased Premises, or place signs on the Leased
Premises which are visible from outside the Leased Premises, without first
obtaining the written consent of Landlord, which consent (or denial thereof)
shall not be unreasonably withheld, conditioned or delayed  if same do not
affect the Building structure or mechanical, electrical or plumbing systems and
are not visible outside the Premises.  Any and all such alterations, physical
additions, or improvements, when made to the Leased Premises by Tenant, shall
at once become the property of Landlord and shall be surrendered to Landlord
upon termination of this Lease by lapse of time or otherwise; provided,
however, this clause shall not apply to movable equipment or furniture owned by
Tenant.  Tenant agrees specifically that no food, soft drink or other vending
machine will be installed within the Leased Premises.  Tenant shall not be
deemed to be the agent or representative of Landlord in making any such
alterations, physical additions or improvements to the Leased Premises, and
shall have no right, power or authority to encumber any interest in the
Building in connection therewith.  However, should any mechanics' or other
liens be filed against any portion of the Building or any interest therein by
reason of Tenant's acts or omissions or because of a claim





                                      -14-
<PAGE>   19
against Tenant or its contractors, Tenant shall cause the same to be cancelled
or discharged of record by bond or otherwise within fifteen (15) days after
notice by Landlord.  If Tenant shall fail to cancel or discharge said lien or
liens, within said fifteen (15) day period, which failure shall be deemed to be
a default hereunder, Landlord may, at its sole option and in addition to any
other remedy of Landlord hereunder, cancel or discharge the same and upon
Landlord's demand, Tenant shall promptly reimburse Landlord for all reasonable
costs incurred in cancelling or discharging such lien or liens.  Landlord shall
have the right at all times to post and keep posted on the Leased Premises any
notices permitted or required by law, or that Landlord shall deem proper for
the protection of Landlord, the Leased Premises, the Building, the Project and
any other party having an interest therein, from mechanics, materialman's and
other liens.

                 4.7     LEGAL USE AND VIOLATIONS OF INSURANCE COVERAGE.

                 (a)     Tenant shall not occupy, use or permit any portion of
the Leased Premises to be occupied or used for any business or purpose that is
disreputable, illegal or creates a fire hazard, or permit anything to be done
within the Leased Premises that would increase the rate of insurance coverage
on the Building and/or its contents.  If Tenant commits any act or permits any
use that increases the cost of any insurance policy required to be carried
hereunder, or that increases the cost to occupy or prepare the Leased Premises
for occupancy, then Tenant shall reimburse Landlord, upon demand, for any such
additional premiums or cost as certified by the insurance carrier as being
solely attributable to Tenant's use of the Leased Premises for other than
general office use.  In connection with such demand for payment of such
increase, Landlord shall deliver to Tenant a written statement setting forth
the amount of any such cost increase and showing in reasonable detail the
manner in which the increase has been allocated to Tenant's acts within or use
of the Leased Premises.

                 (b)     Prior to the Commencement Date and during the Term of
the Lease, except to the extent Landlord did not deliver the Leased Premises in
compliance with laws as of the Commencement Date, Tenant, at Tenant's sole cost
and expense, shall promptly comply with all present and future laws,
ordinances, orders, rules, regulations and requirements of all federal, state,
municipal and local governmental bodies exercising jurisdiction thereover, and
all orders, rules and regulations of any governmental body that may be
applicable to the Leased Premises (and all facilities used in connection
therewith, to the extent that such are reserved for the exclusive use of the
Tenant), whatever the nature of such regulations, including without limitation
environmental rules and regulations, and other governmental or Landlord-imposed
standards governing Tenant's use of, activity within or occupancy of the Leased
Premises for the purpose of insuring compliance with such applicable laws
except to the extent Landlord did not deliver the Leased Premises in compliance
with laws as of the Commencement Date Tenant shall further observe and comply
with the requirements of all policies of public liability, fire and all other
policies of insurance at any time in force with respect to the Building or any
part thereof.  Tenant covenants not to use in, on or about the Leased Premises,
for original construction, or for maintenance, repairs, alterations,
improvements, additions or changes any material or substance prohibited for
such use or in any other similar application prohibited by any governmental
rule, regulation, ordinance, statute or order including, without limitation,
asbestos-





                                      -15-

containing materials.  Tenant shall at all times defend, protect, indemnify,
save and keep harmless the Landlord, its partners, shareholders, directors,
officers, agents and employees from and against all claims, loss, cost, damage
or expense arising out of or from Tenant's breach of this provision.  Tenant
further covenants and agrees that it will not use, keep or suffer to be kept,
or generate or store any hazardous substances, pollutants or contaminants
(collectively "Hazardous Substances") in, upon or about the Leased Premises or
the Building in violation of any applicable law or other than as customary for
an office building tenant.  Tenant shall promptly remove and clean up any
Hazardous Substance brought on, to or about the Leased Premises or the
Building, by Tenant, its agents, employees, contractors, invitees or licensees
in violation of this provision.  Tenant shall indemnify Landlord, its partners,
shareholders, directors, officers, agents and employees for all reasonable
costs and expenses incurred by Landlord to correct any violation of this
covenant, or to remove, neutralize or render harmless any Hazardous Substance,
or to comply with the requirements of any regulatory body having jurisdiction
over Hazardous Substances, or to contest the actions of any such regulatory
body with respect to the Leased Premises or the Building.  Tenant's agreement
to indemnify Landlord, its partners, shareholders, directors, officers, agents
and employees shall survive the expiration of this Lease.

                 4.8     LAWS AND REGULATIONS; RULES OF BUILDING.  Subject to
the provisions of Section 4.7(b), Tenant shall comply with all laws,
ordinances, rules and regulations (state, federal, municipal and other agencies
or bodies having any jurisdiction thereof) relating to the use, condition or
occupancy of the Leased Premises.  Tenant will comply with the rules of the
Building adopted and altered by Landlord from time to time for the safety, care
and cleanliness of the Leased Premises and Building and for preservation of
good order therein (the "Rules and Regulations"), all of which will be sent by
Landlord to Tenant in writing and shall be thereafter carried out and observed
by Tenant.  A copy of the current Rules and Regulations are attached hereto and
made a part hereof as Exhibit D for information purposes only and Landlord
specifically reserves the right in its sole discretion to modify such Rules and
Regulations from time to time as Landlord shall deem necessary and appropriate.

                 4.9     ENTRY FOR REPAIRS AND INSPECTION.  Tenant shall permit
Landlord or its agents or representatives to enter into and upon any part of
the Leased Premises at all reasonable hours to inspect the same, clean or make
repairs, alterations or additions thereto, as Landlord may deem necessary or
desirable, or to show the same to current or prospective purchasers,
mortgagees, investors and/or tenants, provided Landlord does not interfere with
Tenant's use and occupancy of the Leased Premises to any greater extent than is
reasonably necessary, and Tenant shall not be entitled to any abatement or
reduction of rent by reason thereof.

                 4.10    NUISANCE AND ODORS.  Tenant shall conduct its business
and control its agents, employees, invitees, and visitors in such manner as not
to create any nuisance, or interfere with, annoy or disturb any other tenant or
Landlord in its operation of the Building.  Tenant shall not, during occupancy
of, remodeling or construction within the Leased Premises, cause or permit any
strong, unusual, offensive or objectionable odors, gases or vapors to be
produced within the Leased 





                                      -16-
<PAGE>   21
Premises whether such odors, gases or vapors are contained within the Leased 
Premises or migrate from or are permitted by Tenant to be emitted outside of 
the Leased Premises.  Landlord, at its sole discretion, shall determine if any 
such odors, gases or vapors are in violation of this provision.

                 4.11    SUBORDINATION TO MORTGAGE.

                 (a)     This Lease is subject and subordinate to each mortgage
(an "Underlying Mortgage") and each underlying financing or ground lease (an
"Underlying Lease") which may now or subsequently affect Landlord's interest in
the Project.  Tenant agrees, however, that the holder of the Underlying
Mortgage (the "Mortgagee") or the landlord under the Underlying Lease (the
"Prime Landlord") as applicable, may at its option, unilaterally elect to
subordinate, in whole or in part, by an instrument in form and substance
satisfactorily to such party, such Underlying Mortgage or Underlying Lease, as
applicable, to this Lease.  Tenant agrees to execute promptly and to deliver to
Landlord or such party an instrument or instruments confirming the foregoing if
requested by Landlord or such party and agrees that if Tenant fails or refuses
to do so within fifteen (15) days after receipt of written request thereof by
Landlord or such party, such failure or refusal shall constitute a default by
Tenant under this Lease, but such failure or refusal shall in no way affect the
validity or enforceability of this Section 4.11.  Landlord shall request for
Tenant a non-disturbance agreement from each Mortgagee and/or Prime Landlord in
form and substance reasonably acceptable to the parties, but shall have no
obligation if a Mortgagee or Prime Landlord refuses delivery of same.

                 (b)     In the event of the enforcement by the Mortgagee of
the remedies provided for by law or by such Underlying Mortgage, or in the
event of the termination of an Underlying Lease, Tenant shall, upon request of
any person succeeding to the interest of the Mortgagee or upon the request of
the Prime Landlord, automatically become the tenant of such successor in
interest or the Prime Landlord as the case may be, without change in the terms
or provisions of this Lease provided, that neither such successor in interest
nor such Prime Landlord, as applicable, shall be (i) bound by any payment of
the Rent for more than one month in advance except prepayments in the nature of
security for the performance by Tenant of its obligations under this Lease;
(ii) bound by any amendment or modification of this Lease made without the
consent of the Mortgagee or Prime Landlord, as applicable; (iii) liable for any
act, warranty or omission of the prior Landlord under this Lease; (iv) subject
to the offsets, deductions or defenses which Tenant might have arising out of
acts or omissions of Landlord; (v) liable for the breach of any warranties or
obligations relating to construction of improvements for the Project or
leasehold improvements in the Leased Premises performed or to have been
performed by Landlord, or (vi) liable for the return of any security deposit
not delivered to such successor in interest or Prime Landlord, as the case may
be.  At the request of Landlord, a Mortgagee, such successor in interest and/or
Prime Landlord, Tenant shall execute and deliver to such Mortgagee, successor
in interest and/or Prime Landlord a written instrument whereby Tenant confirms
the foregoing attornment.  If Tenant shall fail or refuse to so execute and
deliver such instrument within fifteen (15) days after written request is made,
then Tenant shall be in default under this Lease, but such failure or refusal
shall in no way affect the validity or enforceability of this Section 4.11.





                                      -17-
<PAGE>   22
                 Tenant agrees to give prompt written notice to each Mortgagee
and Prime Landlord who has given Tenant written notice of its address of any
default by Landlord under this Lease which would entitle Tenant to terminate or
cancel this Lease or abate the rent payable hereunder, and agrees that,
notwithstanding any provision of this Lease, no rental abatement or notice of
cancellation or termination on behalf of Tenant shall be effective unless all
such Mortgagees and Prime Landlords have received said notice and have failed
for thirty (30) days of receipt thereof to cure Landlord's default, or if the
default cannot be cured within thirty (30) days, have failed to commence and to
diligently pursue the cure of Landlord's default which gave rise to such right
of cancellation or abatement.

                 4.12    ESTOPPEL CERTIFICATE OR THREE PARTY AGREEMENT. Within
ten (10) business days after receipt of written request therefor by Landlord or
Tenant, the other party shall:

                 (a)     execute estoppel certificates addressed to or enter
into a three-party agreement with (i) any mortgagee or prospective mortgagee or
ground lessor of Landlord, (ii) any purchaser or prospective purchaser of all
or any portion of, or interest in, the Project, or (iii) any investor in the
Project, or (iv) to any prospective purchaser of Tenant's business and/or an
assignee of the Lease or subtenant of the Lease Premises certifying to the best
of the certifying party's knowledge (i) that this Lease is unmodified and in
full force and effect (or if there have been modifications, identifying such
modifications and certifying that the Lease, as modified, is in full force and
effect); (ii) the dates to which the Base Rental and any and all Additional
Rental has been paid; (iii) that the Landlord or Tenant, as the case may be, is
not in default under any provision of this Lease (or if Landlord or Tenant, as
the case may be, is in default, specifying each such default); (iv) the address
to which notices to Landlord or Tenant shall be sent; and (v) other matters as
such mortgagee(s), purchaser(s) or investor may reasonably require; and
agreeing to such notice provisions and other matters as such third party may
reasonably require; and

                 (b)     deliver to Landlord such information regarding the net
worth and financial condition of Tenant as Landlord may reasonably request in
connection with such mortgage, sale or investments to the extent available to
Tenant without incurring any material additional cost or expense to prepare
such information.

                                       V.

                 Landlord and Tenant mutually covenant and agree as follows:

                 5.1     CONDEMNATION AND LOSS OR DAMAGE.  If the Leased
Premises shall be taken or condemned for any public purpose to such an extent
as to render  a material portion of the Leased Premises untenantable, this
Lease shall, at the option of either party, forthwith cease and terminate.
Otherwise, this Lease shall not terminate on account of condemnation.  All
proceeds from any taking or condemnation of the Leased Premises shall belong to
and be paid to Landlord except that Tenant shall be entitled to any element of
damage attributable to Tenant's business or injury thereto, Tenant Extra
Improvements (and other improvements made by or at the expense of Tenant)
and/or the relocation of Tenant provided that Landlord's award is not affected.

                 5.2     DAMAGES FROM CERTAIN CAUSES.  Landlord shall not be
liable or responsible to Tenant for any loss or damage to any property or
person occasioned by theft, fire, act of God, public enemy, injunction, 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 failure to make any such
repairs unless due to the gross negligence or willful misconduct of Landlord,
its agents and/or employees.

                 5.3     LIEN FOR RENT.  In consideration of the mutual
benefits arising under this Lease, Tenant hereby grants to Landlord a lien and
security interest on all tangible property of Tenant now or hereafter placed in
or upon the Leased Premises, and such property shall be and remain subject to
such lien and security interest of Landlord for payment of all rent and other
sums agreed to be paid by Tenant herein.  The provisions of this paragraph
relating to said lien and security interest shall constitute a security
agreement under the Uniform Commercial Code as enacted in the State of Texas so
that Landlord shall have and may enforce a security interest on all tangible
property of Tenant now or hereafter placed in or on the Leased Premises,
including but not limited to all fixtures, machinery, equipment, furnishings
and other articles of personal property now or hereafter placed in or upon the
Leased Premises by Tenant.  Tenant agrees to execute as debtor such financing
statement or statements as Landlord may now or hereafter reasonably request in
order that such security interest or interests may be protected pursuant to
said Code.  Landlord may at its sole cost and expense and upon its election at
any time file a copy of this Lease as a financing statement.  Landlord, as
secured party, shall be entitled to all of the rights and remedies afforded a
secured party under said Code in addition to and cumulative of the landlord's
liens and rights provided by law or by the other terms and provisions of this
Lease.

                 5.4     LANDLORD'S RIGHT TO RELET.  In the event of default by
Tenant in any of the terms or covenants of this Lease or in the event the
Leased Premises are abandoned by Tenant, Landlord shall have the right, but not
the obligation, to relet same for the remainder of the Term, and if the rent
received through reletting does not at least equal the rent provided for
herein, Tenant shall pay and satisfy the deficiency between the amount of the
rent so provided for and that received through reletting, including, but not
limited to, the reasonable cost of renovating, altering and decorating for a
new occupant.





                                      -19-
<PAGE>   24
Nothing herein shall be construed as in any way denying Landlord the right, in
the event of abandonment of said premises or other breach of this Lease by
Tenant, to treat the same as an entire breach and at Landlord's option to
terminate this Lease and/or immediately seek recovery for the entire breach of
this Lease and any and all damages which Landlord suffers thereby.

                 5.5     HOLDING OVER.  In the event of holding over by Tenant
after expiration or termination of this Lease without the written consent of
Landlord, Tenant shall pay as rental during the holdover period double the
greater of (A) the Base Rental and Additional Rental payable immediately prior
to the expiration or termination, or (B) then prevailing market rental rate for
the Leased Premises.  No holding over by Tenant after the Term shall be
construed to extend the Lease.  In the event of any unauthorized holding over,
Tenant shall indemnify Landlord against all claims for damages by any tenant to
whom Landlord may have leased all or any part of the Leased Premises effective
upon the termination of this Lease and for any other reasonable loss, cost,
damage or expense (including reasonable attorneys' fees and costs of suit)
incurred by Landlord as a result of such holding over.  Any holding over with
the consent of Landlord in writing shall thereafter constitute a lease from
month to month.

                 5.6     CASUALTY.  In the event of a fire or other casualty in
the Leased Premises, Tenant shall immediately give notice thereof to Landlord.
If the Leased Premises shall be partially destroyed by fire or other casualty
so as to render the Leased Premises untenantable in whole or in part, the
rental provided for herein shall abate thereafter as to the portion of the
Leased Premises rendered untenantable until such time as the Leased Premises
are made tenantable and Landlord agrees to commence and prosecute such repair
work promptly and with all due diligence.  Notwithstanding the foregoing, in
the event such destruction results in the Leased Premises being untenantable in
whole or in substantial part for a period reasonably estimated by a responsible
contractor selected by Landlord to be one year or longer after the casualty, or
in the event of total or substantial damage or destruction of the Building from
any cause (which shall mean any damage of greater than fifty (50%) of the
insurable value of the Building and/or any damage which requires more than one
year to repair), then Landlord shall have the right to terminate this Lease and
all rent owed up to the time of such destruction or termination shall be paid
by Tenant (it being understood that Tenant shall pay rent on all tenantable
space until termination of this Lease).  Landlord shall give Tenant written
notice of its decisions, estimates or elections under this Section 5.6 within
sixty (60) days after any such damage or destruction.  In the event of
destruction to the Leased Premises resulting in the same being untenantable in
whole or in substantial part for a period reasonably estimated by a responsible
contractor selected by Landlord to be one year or longer after the date of the
casualty and Landlord has not terminated this Lease as herein provided, then
Tenant shall have the right, within thirty (30) days after Landlord delivers
the estimate to Tenant of time to restore, to terminate this Lease by written
notice to Landlord.  Notwithstanding anything contained in this Section 5.6,
Landlord shall be obligated to restore or rebuild only the portion of the
Leased Premises which consists of building standard improvements, and nothing
herein shall be construed to obligate Landlord under any circumstances to
repair or restore any other tenant finish work.

                 5.7     ATTORNEYS' FEES.  In the event Tenant makes default in
the performance of any of the terms, covenants, agreements or conditions
contained in this Lease and Landlord places the

enforcement of this Lease, or any part thereof, or the collection of any rent
due, or to become due hereunder or recovery of the possession of the Leased
Premises in the hands of an attorney, or files suit upon same, Tenant agrees to
pay Landlord reasonable attorneys' fees to Landlord plus court costs in the
event Landlord prevails in such matter.  Moreover, Landlord agrees to pay
Tenant reasonable attorneys' fees and court costs in the event Tenant prevails
in any action against Landlord.

                 5.8     ALTERATION. This Lease may not be altered, changed or
amended, except by an instrument in writing signed by both parties hereto.

                 5.9     ASSIGNMENT BY LANDLORD.  Landlord or any
successor-in-interest to Landlord shall have the right to transfer and assign,
in whole or in part, all its rights and obligations hereunder and in the
Project and property referred to herein, and in such event and upon the
transferee Landlord's assumption of transferor Landlord's obligations
thereafter accruing hereunder (any such transferee to have the benefit of, and
be subject to, the provisions of Section 3.6) no further liability or
obligation shall thereafter accrue against Landlord hereunder.  Upon request by
transferor Landlord, Tenant agrees to execute a certificate certifying such
facts (if true) as transferor Landlord may reasonably require in connection
with any such assignment by transferor Landlord.

                 5.10    DEFAULT BY TENANT.  If (i) default shall be made in
the payment of any sum to be paid by Tenant under this Lease, and default shall
continue for ten (10) days after delivery (or attempted but refused delivery)
of notice from Landlord (provided that Landlord shall only be obligated to give
Tenant notice of any monetary default twice in any twelve (12) month period,
and thereafter Tenant shall be deemed in default within ten (10) days after
failure to make such payment without requirement of notice from Landlord), or
(ii) default shall be made in the performance of any of the other covenants or
conditions that Tenant is required to observe and to perform, and such default
shall continue for twenty (20) days, or (iii) if the interest of Tenant under
this Lease shall be levied on under execution or other legal process, or (iv)
if any petition shall be filed by or against Tenant to declare Tenant a
bankrupt or to delay, reduce or modify Tenant's debts or obligations, or (v) if
any petition shall be filed or other action taken to reorganize or modify
Tenant's capital structure if Tenant be a corporation or other entity, or (vi)
if Tenant be declared insolvent according to law, or (vii) if any assignment of
Tenant's property shall be made for the benefit of creditors, or (viii) if a
receiver or trustee is appointed for Tenant or its property, or (ix) if Tenant
shall abandon the Leased Premises during the Term or any renewals or extensions
thereof (any of (i) through (ix) is herein called an "Event of Default"), then
Landlord may treat the occurrence of any one or more of the Events of Default
as a breach of this Lease (provided that no such levy, execution, legal
process, declaration, appointment or petition filed against Tenant shall
constitute a breach of this Lease if Tenant shall contest the same by
appropriate proceedings and shall remove or vacate the same within ninety (90)
days from the date of its creation, service or filing) and thereupon, at
Landlord's option, may have any one or more of the following described remedies
in addition to all other rights and remedies provided at law or in equity:

                 (a)     Landlord may terminate this Lease and forthwith
repossess the Leased Premises and be entitled to recover forthwith as damages a
sum of money equal to the total of (i) the cost of





                                      -21-
<PAGE>   26
recovering the Leased Premises, (ii) the unpaid rent earned at the time of
termination, plus interest thereon at the Maximum Rate thereon from the due
date, (iii) the balance of the rent for the remainder of the Term less the fair
market value of the Leased Premises for said period, as determined by Landlord
and (iv) any other sum of money and damages owed by Tenant to Landlord.

                 (b)     Landlord may terminate Tenant's right of possession
(but not this Lease) and may repossess the Leased Premises by forcible entry or
detainer suit or otherwise, without demand or notice of any kind to Tenant and
without terminating this Lease, in which event Landlord may, but shall be under
no obligation to do so, relet the same for the account of Tenant for such rent
and upon such terms as shall be reasonably satisfactory to Landlord.  For the
purpose of such reletting, Landlord is authorized to make any repairs, changes,
alterations or additions in or to the Leased Premises that may be necessary,
and (a) if Landlord shall fail or refuse to relet the Leased Premises, or (b)
if the same are relet and a sufficient sum shall not be realized from such
reletting after paying (i) the unpaid rent due hereunder earned but unpaid at
the time of reletting plus interest thereon at the Maximum Rate thereon, (ii)
the reasonable cost of recovering possession, (iii) all of the reasonable costs
and expenses of repairs, changes, alterations and additions and (iv) the
reasonable expense of such reletting and of the collection of the rent accruing
therefrom to satisfy the rent provided for in this Lease to be paid, then
Tenant shall pay to Landlord as damages a sum equal to the amount of the rental
reserved in this Lease for such period or periods, or if the Leased Premises
have been relet, the Tenant shall satisfy and pay any such deficiency upon
demand therefor from time to time and Tenant agrees that Landlord may file suit
to recover any sums falling due under the terms of this Section 5.10(b) from
time to time, and that no delivery to or recovery of any portion due Landlord
hereunder shall be any defense in any action to recover any amount not
theretofore reduced to judgment in favor of Landlord, nor shall such reletting
be construed as an election on the part of Landlord to terminate this Lease
unless a written notice of such intention be given to Tenant by Landlord.
Notwithstanding any such reletting without termination, Landlord may at any
time thereafter elect to terminate this Lease for such previous breach.

                 (c)     Upon any such default by Tenant in the payment of rent
as required by this Lease, Landlord or Landlord's agent may change the door
lock of the Leased Premises.  In such event, Landlord or its agent shall place
a written notice on Tenant's front door stating the name and the address or
telephone number of the individual or company from which the new key may be
obtained.  The new key may be obtained (i) only during Tenant's regular
business hours and (ii) only upon payment in full of the delinquent rent.
Landlord may lock out Tenant in the event of any such default without being
deemed in any manner guilty of conversion, trespass, eviction, or forcible
entry or detainer, without incurring any liability for any damage, claim, or
cause of action resulting therefrom and without relinquishing any other right
or rights given to Landlord hereunder or by operation of law or in equity.  If
Landlord shall violate the provisions of this subparagraph, Tenant's sole
remedy shall be to recover possession of the Leased Premises and Tenant
expressly waives any and all rights and remedies under Section 93.002(g) of the
Texas Property Code, as amended.  As provided in Section 93.002(h) of the Texas
Property Code, the terms and provisions of this subparagraph of the Lease
supersede the terms and conditions of said Section 93.002 to the extent of any
conflict between the two provisions.

<PAGE>   27
                 (d)     All past due rent and other amounts due hereunder
shall bear interest at the Maximum Rate.

                 5.11    NON-WAIVER. Failure of Landlord to declare any default
immediately upon occurrence thereof, or delay in taking any action in
connection therewith, shall not waive such default nor constitute a waiver of
any future default, but Landlord shall have the right to declare any such
default at any time and take such action as might be lawful or authorized
hereunder, either in law or in equity.  Neither the acceptance by Landlord of
rent or any other payment hereunder, whether or not any default hereunder by
Tenant is then known to Landlord, nor any custom or practice followed in
connection with this Lease, shall constitute a waiver of any of Tenant's
obligations under this Lease.

                 5.12    CASUALTY INSURANCE.

                 (a)     At all times during the Term, Landlord shall maintain,
or cause to be maintained, at Landlord's expense (which expense will be an
Operating Expense under Section 2.4(c) of this Lease), a policy or policies of
insurance with the premiums thereon fully paid in advance, issued by and
binding upon an insurance company of good financial standing authorized to do
business in Texas, insuring the Building and the Building Standard improvements
against loss or damage by fire or other insurable hazards and contingencies in
amounts selected by Landlord; provided, however, that Landlord shall not be
obligated to insure any furniture, equipment, machinery, goods or supplies not
covered by this Lease that Tenant may keep or maintain in the Leased Premises,
or any non-Building Standard improvements or alterations that Tenant may make
upon the Leased Premises.  If the annual premiums charged Landlord for such
casualty insurance exceed the standard premium rates because the nature of
Tenant's operations result in extra-hazardous or higher than normal risk
exposure, then Tenant shall, upon receipt of appropriate premium invoices,
reimburse Landlord for such increases in premium.  Any payments for losses
under Landlord's casualty insurance shall be made solely to Landlord and the
mortgagee.

                 (b)     At all times during the Term, Tenant shall maintain
insurance coverage against loss or damage by fire and such other risks as are
from time to time included in a standard or special extended coverage
endorsement insuring the full insurable value of any non-Building Standard
improvements, any alterations, Tenant's trade fixtures, furnishings, equipment,
and all other items of personal property of Tenant.  All policies required to
be carried by Tenant under this Section 5.12(b) shall be written with
financially responsible insurance companies authorized to do business in Texas
and with a Best & Company rating of "B+, IX" or better, and all evidence of
insurance provided to Landlord shall contain an endorsement naming Landlord as
an additional insured and at least thirty (30) days' prior written notice of
cancellation to Landlord.  Tenant shall deliver to Landlord a certificate of
insurance outlining the insurance required herein at least fifteen (15) days
prior to the Commencement Date and fifteen (15) days prior to all renewals
thereof.  Any self-insurance policies maintained by Tenant shall be subject to
Landlord's prior written approval.  If Tenant fails to provide evidence of
insurance required hereunder, prior to commencement of the Term, and thereafter
during the Term, within fifteen (15) days prior to the expiration date of any
such coverage, Landlord shall be authorized (but not required) after written
notice of its intention to do so, and Tenant's failure to obtain such insurance
and provide reasonably evidence





                                      -23-
<PAGE>   28
thereof to Landlord within one (1) business day after Tenant's receipt of such
notice, to procure such coverage in the amounts stated with all costs thereof
to be charged to Tenant and paid upon written invoice therefor as Additional
Rental.

                 5.13    LIABILITY INSURANCE.  Landlord (with respect to the
Project) and Tenant (with respect to the Leased Premises and Project) shall
each maintain or cause to be maintained a policy or policies of commercial
general liability insurance (including contractual liability coverage) with the
premiums thereon fully paid in advance, issued by and binding upon an insurance
company of good financial standing, authorized to do business in Texas and
having a Best & Company rating of "B+, XIII" or better, such insurance to
afford a minimum protection of not less than One Million Dollars
($1,000,000.00) combined single limit bodily injury and property damage in any
one occurrence.  Tenant's contractual liability insurance shall apply, without
limitation, to all of Tenant's indemnity obligations under this Lease.
Tenant's insurance required hereunder shall name Landlord as an additional
insured and shall contain endorsements and provisions stating that Tenant's
insurance is primary to any insurance otherwise carried by Landlord and that
Landlord will receive thirty (30) days' prior written notice of cancellation of
the policy.  Tenant shall deliver to Landlord a certificate of insurance
outlining the insurance required herein at least fifteen (15) days prior to the
Commencement Date and fifteen (15) days prior to all renewals thereof.  The
expense for Landlord's liability insurance will be an Operating Expense under
Section 2.4(c) of this Lease.  Upon request of Tenant, Landlord shall provide
Tenant reasonable evidence that the insurance required to be maintained
hereunder by Landlord is in full force and effect.

                 5.14    HOLD HARMLESS.  Landlord and any mortgagee of Landlord
shall not be liable to Tenant for any damage to person or property caused by
the intentional torts or negligence of Tenant, its agents or employees, and
Tenant agrees to indemnify and hold Landlord harmless from all liability and
claims for any such damage.  Tenant shall not be liable to Landlord for any
damage to person or property caused by the intentional torts or negligence of
Landlord, its agents or employees, and Landlord agrees to indemnify and hold
Tenant harmless from all claims for such damage.  In the event a claim or
damage is the result of the joint negligence or joint intentional torts of
Tenant, its agents or employees, on the one hand, and Landlord, its agents or
employees, on the other hand, the foregoing indemnities shall apply only to the
portion of the damage attributable to the negligence or intentional tort of the
applicable indemnifying party.

                 5.15    WAIVER OF SUBROGATION RIGHTS.  Anything in this Lease
to the contrary notwithstanding, Landlord and Tenant each hereby waives any and
all rights of recovery, claim, action or cause of action, against the other,
its agents, officers, employees, partners, servants or shareholders for any
loss or damage that may occur to the Leased Premises, or any improvements
thereto or said Building of which the Leased Premises are a part, or any
improvements thereto, or any personal property of such party therein, by reason
of fire, the elements, or any other cause which is required to be insured
against under the terms of standard fire and extended coverage insurance
policies referred to in Section 5.12 hereof, regardless of cause or origin,
including negligence of the other party hereto, its agents, officers,
employees, partners, servants or shareholders and each party shall cause such
insurance policies to contain provisions or endorsements wherein each insurer
waives its rights of recovery against such parties.

                 5.16    ENTIRE AGREEMENT, REPRESENTATIONS, ETC.  This Lease
contains the entire agreement of the parties pertaining to the subject matter
hereof and supersedes all other prior and contemporaneous agreements and
understandings, both oral and written, of the parties in connection therewith.
No other written or oral promises or representations have been made and none
have been relied upon, and none shall be binding.  This Lease supersedes and
replaces any previous Lease between the parties, including any renewals or
extensions thereunder.  Landlord's agents do not and will not have authority to
(a) make exceptions, changes or amendments to this Lease or factual
representations not expressly contained in this Lease, (b) waive any right,
requirement, or provision of this Lease, or (c) release Tenant from all or part

Agreement.  The parties executing this Agreement have relied solely and
completely upon their own judgment and the advice of their own attorneys in
entering into this Agreement.

                 5.17    TIME IS OF THE ESSENCE.  Time is of the essence and
all performance due dates, time schedules, and conditions precedent to
exercising a right shall be strictly adhered to without delay except where
otherwise expressly provided.

                 5.18    BROKERS.  Tenant hereby warrants and represents that
it has not dealt with any other brokers or intermediaries entitled to any
compensation in connection with this Lease or Tenant's occupancy of space in
the Leased Premises except for Boyd, Page & Associates and for which Landlord
shall be responsible for any commission or fee due them.  Each party hereby
agrees to hold the other party, its partners and representatives harmless from
any and all claims, liabilities, costs and expenses (including reasonable
attorneys' fees) arising from any claim for any commissions or other fees by
any other broker or agent acting or purporting to have acted on behalf of such
party.

                 5.19    NO WARRANTIES.  TENANT HEREBY WAIVES ANY AND ALL
WARRANTIES, EXPRESS OR IMPLIED, WITH RESPECT TO THE LEASED PREMISES WHICH MAY

address for such party specified in this Lease, or to such other place as the
party to be notified may from time to time designate by at least fifteen (15)
days' notice to the notifying party.

                 5.23    SEVERABILITY.  If any term or provision of this Lease,
or the application thereof to any person or circumstance shall to any extent be
invalid or unenforceable, the remainder of this Lease, or the application of
such provision to persons or circumstances other than those as to which it is
invalid or unenforceable, shall not be affected thereby.  Each provision of
this Lease shall be valid and shall be enforceable to the extent permitted by
law.

                 5.24    AUTHORITY.  (a)  Tenant represents to Landlord that
(a) Tenant is a corporation duly formed, validly existing and in good standing
under the laws of the State of Maryland, (b) that the person executing this
Lease on behalf of Tenant was authorized to do so, (c) all consents or
approvals required of third parties (including, but not limited to, its Board
of Directors or partners) for the execution, delivery and performance of this
Lease have been obtained and (d) upon request of Landlord, Tenant will deliver

Lease on behalf of Tenant.

                 (b)     Landlord represents to Tenant that (a) Landlord is a
partnership duly formed, validly existing and in good standing under the laws

                 5.25    RELOCATION. Landlord shall have the one time option to
relocate the Tenant to alternative space in the Building, which alternative
space shall be of comparable size to or larger than the Leased Premises.
Landlord shall give Tenant not less than ninety (90) days prior written notice
of such relocation, which notice shall include the date on which the Tenant
shall be required to relocate or move and a description of the space to which
Tenant will be relocated.  Landlord shall promptly pay all out-of-pocket costs
and expenses of relocating Tenant (and the cost of preparing such comparable
space for occupancy) including the construction of any Tenant leasehold
improvements to make such space comparable to the Leased Premises.  However, if
Tenant is relocated prior to occupancy and fitting out the Leased Premises with
tenant improvements, Landlord shall only be required to pay the costs otherwise
agreed to be paid by Landlord under this Lease for construction of tenant
improvements plus costs and expenses incident to changes in the tenant
improvements as a result of such relocation in excess of those which would have
been borne by Tenant if there had been no relocation.  In the event of such
relocation, such alternative space shall for all purposes be deemed the Leased
Premises hereunder and this Lease shall continue in full force and effect
without any change in the other terms or conditions hereof.

                 5.26    RENEWAL OPTION





                                      -26-
<PAGE>   31
                 (a)     So long as an Event of Default is not in existence and
subject to the provisions of this Section 5.26, Tenant is hereby granted a one
(1) time option to renew ("Renewal Option") the Initial Term as to all (but not
part) of the Leased Premises for a period of five (5) years (the "Renewal
Term"), such Renewal Term to commence at the expiration of the Initial Term.
Tenant must furnish Landlord with written notice of its to exercise the Renewal
Option twelve (12) months prior to the expiration of the Initial Term (the
"Renewal Intent Notice").  If Tenant timely delivers the Renewal Intent Notice
to Landlord, Landlord shall, no later than fifteen (15) days after Landlord's
receipt thereof, deliver to Tenant written notice (the "Rate Notice") of the
Market Base Rental Rate (defined below) and the Basic Parking Charge for the
Parking Permits (each as defined in Exhibit C) (if applicable pursuant to
Section 5.26 (b) (iii) below).

                 If Tenant objects to Landlord's determination of the Market
Base Rental Rate and the Basic Parking Charge, Landlord and Tenant shall work
diligently to attempt to resolve their differences as to the Market Base Rental
Rate within forty-five (45) days after Tenant's receipt of the Rate Notice (the
"Renewal Election Period").  If Landlord and Tenant agree in writing as to the
Market Base Rental Rate and the Basic Parking Charge prior to the expiration of
the Renewal Election Period, the Market Base Rental Rate so agreed to by
Landlord and Tenant shall be applicable if Tenant, in its sole discretion,
elects to exercise the Renewal Option prior to the expiration of the Renewal
Election Period.  If Tenant timely furnishes the Renewal Intent Notice to
Landlord and Tenant, in its sole discretion, exercises the Renewal Option prior
to the expiration of the Renewal Election Period and prior to Landlord and
Tenant agreeing in writing as to the Market Base Rental Rate for the Renewal
Term, Tenant's exercise of the Renewal Option shall constitute Tenant's
irrevocable election to exercise the Renewal Option and irrevocable agreement
to Landlord's determination of the Market Base Rental Rate as contained in the
Rate Notice.  Tenant must notify Landlord in writing (the "Election Notice")
prior to the expiration of the Renewal Election Period if Tenant elects to
exercise the Renewal Option.  If Tenant timely delivers the Renewal Intent
Notice and the Election Notice to Landlord, but at any time prior to the
commencement of the Renewal Term an Event of Default occurs Landlord, at its
sole option during the continuance of such Event of Default, may terminate
Tenant's election to exercise the Renewal Option and the Renewal Option shall
expire and thereafter not be exercisable by Tenant.  If Tenant fails to timely
exercise the Renewal Option by failing to timely deliver the Renewal Intent
Notice or the Election Notice as provided above, the Renewal Option shall
automatically terminate, and Tenant shall have waived forever its right to
renew and extend the Initial Term.

                 (b)     The renewal of this Lease pursuant to the exercise of
the Renewal Option shall be upon the same terms and conditions of this Lease,
except:

                         (i)      The Base Rental Rate for the Leased Premises
during the Renewal Term shall be the sum of (A) the Base Rental Rate for the
Leased Premises in effect for the year immediately preceding the commencement
of the Renewal Term, less the Tenant's Proportionate Share of the Base Year's
Basic Costs (on a per square foot of Net Rentable Area basis) determined in
accordance with the provisions of Section 2.4 (a); plus (B) the increase in the
Market Base Rental Rate over the rate in (A); plus, (C) the Expense Stop
(defined below) for the Renewal Period (as determined by clause (ii) below);





                                      -27-
<PAGE>   32
provided, however, in the event the Market Base Rental Rate is less than or
equal to the rate in (A), the Base Rental Rate for the Leased Premises during
the Renewal Term shall be the sum of the amounts in (A) and (C).  Additionally,
Tenant shall be obligated to pay as part of Base Rental a management fee of
three percent (3%) of Tenant's Base Rental and Additional Rental as provided in
Section 2.3.  Tenant shall be obligated to pay the Additional Rental pursuant
to Section 2.4 and 2.5 of this Lease (taking into account the adjustments
pursuant to clause (ii) below).

                         (ii)     For purposes of determining the Additional
Rental payable by Tenant after the expiration of the calendar year in which the
Renewal Term occurs, Section 2.4 (a) of this Lease shall be amended to
recognize that during the Renewal Term Tenant shall pay as Additional Rental
Tenant's Proportionate Share of all Basic Costs in excess of the Expense Stop
(defined below).  As used in this clause (ii), "Expense Stop" shall mean
Landlord's good faith determination in accordance with generally accepted
accounting principles of the Basic Costs (on a per square foot of Net Rentable
basis) for the calendar year in which the Renewal Term commences.

                         (iii)    Tenant shall lease the Parking Permits
determined in accordance with Exhibit C of this Lease at the commencement of
the Renewal Term, and Tenant shall pay Landlord, as the Basic Parking Charge, a
monthly amount equal to the rates then being charged by Landlord or the
operator of the Garage for parking in such location (taking into account
whether such parking spaces are for assigned or unassigned parking spaces) for
monthly contract parking in the Garage multiplied by the number of Parking
Permits leased by Tenant pursuant to this Lease, which Basic Parking Charge
shall be payable as provided in Exhibit C hereto.

                         (iv)     Tenant shall have no option to renew this
Lease beyond the Renewal Term; and

                         (v)      Subject to the terms of the Lease, the
leasehold improvements will be provided in their then-existing condition (on an
"as is" basis) at the time the Renewal Term commences and Tenant shall not be
entitled to any construction, buildout or other allowances with respect to the
Leased Premises during the Renewal Term.

                 (c)     As used in this Lease, the term "Market Base Rental
Rate" shall mean the market annual net rental rate (exclusive of building or
project expense pass through additions, whether characterized as such or not,
and exclusive of any portion of "base rentals" attributable to building or
project expenses or to an "expense stop") per square foot of Net Rentable Area
of the applicable space and for the time period as to which such rate is being
determined, that a willing tenant would pay and a willing landlord would
accept, in arm's length bona fide negotiations (taking into consideration all
relevant factors including, without limitation, the following factors:  rent
being charged in other first-class office buildings located within the
Greenspoint Town Center, for leases then being entered into for comparable
space to the Leased Premises in the comparable elevator bank for which the
Market Base Rental Rate is being determined; location, quality, amenities, age
and reputation of the buildings in which the space being compared is located;
use and size of the space under comparison; location and/or floor level of the
subject

space and any comparison space within their respective buildings, including
view, elevator lobby exposure, etc.;  definition of "net rentable area"

                                   EXHIBIT B


                        TENANT IMPROVEMENT WORK SCHEDULE


                 1.       Preparation of Tenant Plans.

                 (a)      Landlord shall provide and submit to Tenant for its
approval the  Tenant Plans (hereinafter defined) necessary to price and
construct the Building Standard Improvements and any work in addition to
Building Standard Improvements ("Tenant Extra Improvements") desired by Tenant.
Building Standard Improvements and Tenant Extra Improvements are herein
referred to as "Tenant Improvements."

                 (b)      "Tenant Plans" means complete sets (at least three
prints and one reproducible copy) of architectural, structural, mechanical,
electrical and plumbing working drawings for any and all Tenant Improvements
(which shall include such written instructions or specifications as may be
necessary to secure a building permit from the City of Houston and shall show
the full detailed scope of all Tenant Improvements).  The Tenant Plans shall be
consistent with and shall conform to the Building plans and specifications and
all applicable laws, regulations, rules, ordinances and codes, which shall be
the obligation of Landlord.  The structural, mechanical, electrical and
plumbing portions of the Tenant Plans shall be prepared (at Landlord's expense)
by Landlord's engineers.

                 (c)      The cost of preparing the Tenant Plans, including any
changes thereto, shall be paid by Tenant; provided that Landlord shall
contribute thereto $1.50 per square foot of Net Rentable Area of the Leased
Premises toward the cost of Tenant Plans.

                 (d)      The Tenant Plans must be completed on or prior to
February 3, 1997.  Accordingly, Landlord shall submit the same for Tenant's
approval on or prior to February 3, 1997 and Tenant agrees to review the same
and respond to Landlord within five (5) days after the day of receipt thereof.

                 2.       Pricing of Tenant Plans.

                 (a)      Landlord shall promptly submit the Tenant Plans which
have been approved by Tenant to the Landlord's contractor ("Landlord's
Contractor") for pricing of the Tenant Improvements. Promptly following the
receipt by Landlord of such pricing by Landlord's Contractor, Landlord shall
submit to Tenant for its approval a pricing letter (the "Pricing Letter"),
including a detailed cost breakdown, based on the proposal of Landlord's
Contractor.





                                      -1-
<PAGE>   37
                 (b)      Tenant shall have two (2) days after the date of
submission within which to approve or disapprove the Pricing Letter.  The
Pricing Letter shall be deemed approved unless Tenant gives notice of
disapproval within such two (2) day period.  If the Pricing Letter is
disapproved, Tenant shall provide, with its notice of disapproval, such
information as may be required to revise the Tenant Plans for Tenant
Improvements to reduce the cost of performing the work of Tenant Extra
Improvements.  The additional information shall be submitted to Landlord's
Contractor for a cost estimate, with Tenant again having a right to approve or
disapprove the same pursuant to the foregoing procedures.  The process shall
continue for a reasonable time until revised Tenant Plans have been finalized
and completed in conjunction with approval of a Pricing Letter acceptable to
Tenant.

                 (c)      The Pricing Letter must be approved and executed by
Tenant on or prior  to February 10, 1997.  If, however, such approval and
execution is not accomplished on or prior to February 10, 1997, Landlord shall
have the right, at its option, to terminate this Lease (without waiving any
other rights Landlord may have).

                 3.       Construction of Tenant Improvements.

                 (a)      After receipt and approval of Tenant's Plans and the
Pricing Letter, Landlord shall administer the construction of Tenant
Improvements in accordance with the approved construction documents and
proposal of Landlord's Contractor; provided, however, that no Tenant
Improvements shall be installed which do not conform to Building plans and
specifications or to any applicable regulations, laws, ordinances, codes and
rules.  Such conformity shall be the obligation of Tenant.

                 (b)      Landlord shall bear the cost of the construction of
Tenant Improvements.  If Tenant accepts the Pricing Letter, Landlord shall
contribute $16.90 per square foot of Net Rentable Area to Tenant Improvements.
Such allowance shall be credited against amounts due Landlord under paragraph
3(b) of this Exhibit B for Tenant Improvements as the work progresses.  The
credit given for Tenant Improvements covered by each monthly draw shall equal a
fraction thereof, the numerator of which is the total allowance provided by
Landlord and the denominator of which is the total cost of all Tenant
Improvements.  All costs incurred in construction of Tenant Improvements shall
be increased by a charge, to be paid by Tenant, of ten percent (10%) to
reimburse Landlord for construction administration and coordination.  Tenant
shall pay to Landlord all amounts payable by Tenant pursuant to this Exhibit B
within ten (10) days after completion of the Tenant Improvements.

                 (c)      All Tenant Improvements shall be constructed by
Landlord's Contractor with the exception of telephone equipment and wiring
which may be installed by Tenant subject to the limitations contained herein.
All such equipment furnished and installed by Tenant shall be installed in a
manner which conforms with Landlord's Contractor's schedule, and the work or
installation shall be handled in such a manner as not to materially interfere
with or delay the work of Landlord's Contractor to any extent unsatisfactory to
Landlord.  No portion of the work to be performed by Landlord's Contractor
shall be dependent upon completion of any work or construction or installation
to be performed by Tenant.

<PAGE>   38
                 (d)      It is agreed that Tenant may authorize changes in the
Tenant Improvements, provided that any changes must meet the criteria set forth
in paragraph l(b) above.  Tenant shall pay any net increase in cost and/or
credited with any savings (such credit be applied to Base Rental next becoming
due) which results from such changes (including the cost of all modifications
to Tenant Improvements which have theretofore been initiated or constructed and
any modifications required to the base building), plus ten percent (10%)
thereof as an administrative cost recovery fee.

                 4.       Substantial Completion and Commencement Date.

                 (a)      "Substantial Completion" of the Leased Premises shall
mean substantial completion of the Tenant Improvements in accordance with the
Tenant Plans, with a punch-list of uncompleted items which do not interfere in
any material respect with the use or enjoyment of the Leased Premises and which
permits Landlord to obtain any and all occupancy permits or authorizations
necessary to Tenant's use and occupancy of the Leased Premises.

                 (b)      Notwithstanding Section 2.1(a) of this Lease, the
Commencement Date of the Term of this Lease shall be the earlier of (i) the
date of occupancy of the Leased Premises by Tenant, (ii) the date of
Substantial Completion of the Leased Premises (but in no event earlier than
April 1, 1997), or (iii) the date Substantial Completion would have occurred
but for Tenant Delay.  If such a date is not that established as the
Commencement Date in Section 2.1 of this Lease, such date shall be revised
accordingly.  In addition, if the Commencement Date is revised, in no event
shall the Lease expire later than April 30, 2002.

                 (c)      "Tenant Delay", as used herein, means delays in
Substantial Completion of the Leased Premises to the extent resulting from (i)
Tenant's failure to meet the dates established in paragraphs 1 and 2 for
submission and approval of Tenant Plans and the Pricing Letter, (ii) High-risk
Items, as defined below, and (iii) any other delays caused by Tenant, its
architect, engineers, consultants, agents, contractors or subcontractors, in
completing the Tenant Improvements, including delays caused by changes
requested by Tenant.  "High-risk Items" means Tenant Extra Improvements which
Landlord acting in good faith reasonably believes have a probability of not
being completed by the originally scheduled Commencement Date (due to limited
supplies or suppliers, length of time to be manufactured, delivered or
installed or otherwise and which have been identified as such with the
agreement of Tenant on the Tenant Plans).  Landlord shall designate any
High-risk Items at or prior to the time of approval of the Pricing Letter (or
any revisions thereof on which the same appear).

                 (d)      LANDLORD SHALL MAKE NO, AND DOES NOT MAKE ANY,
WARRANTIES, EXPRESS OR IMPLIED, WITH RESPECT TO THE TENANT IMPROVEMENTS.
LANDLORD SHALL NOT BE RESPONSIBLE FOR ANY OF THE WARRANTIES OR COVENANTS FROM
ANY CONTRACTOR TO TENANT, BUT LANDLORD WILL ASSIST TENANT IN ENFORCING SUCH
WARRANTIES AND COVENANTS FROM CONTRACTORS AT TENANT'S COST AND EXPENSE.  ALL
IMPLIED WARRANTIES, INCLUDING BUT NOT LIMITED TO THOSE OF MERCHANTABILITY AND
FITNESS FOR A PARTICULAR PURPOSE,





                                      -3-

ARE EXPRESSLY NEGATED AND WAIVED.  WITHOUT LIMITING THE FOREGOING, LANDLORD
SHALL NOT BE RESPONSIBLE FOR FAILURE OF THE TENANT IMPROVEMENTS TO BE COMPLETED
IN A TIMELY MANNER, TO BE COMPLETED IN ACCORDANCE WITH THE TENANT PLANS, OR
OTHERWISE.

                 (e)      LANDLORD WILL NOT BE RESPONSIBLE FOR, AND WILL NOT
HAVE CONTROL OR CHARGE OF, CONSTRUCTION MEANS, METHODS, TECHNIQUES, SEQUENCES
OR PROCEDURES, OR FOR SAFETY PRECAUTIONS AND PROGRAMS IN CONNECTION WITH SUCH
TENANT IMPROVEMENTS, AND IT WILL NOT BE RESPONSIBLE FOR ANY CONTRACTOR'S
FAILURE TO CARRY OUT SUCH TENANT IMPROVEMENTS.  LANDLORD WILL NOT BE
RESPONSIBLE FOR, OR HAVE CONTROL OR CHARGE OVER, THE ACTS OR OMISSIONS OF
TENANT'S CONTRACTORS, OR THEIR AGENTS OR EMPLOYEES.  LANDLORD IS ACTING SOLELY
AS A CONSULTANT TO TENANT WITH RESPECT TO ADMINISTERING SUCH WORK, BUT IS NOT
ACTING AS A CONTRACTOR, AND IS NOT GUARANTEEING THE PERFORMANCE OF SUCH WORK.

                               ICARUS CORPORATION
                                 (THE "TENANT")


                 Tenant shall at all times during the Term lease between six
(6) and eleven (11) permits to park vehicles in the following garage (the
"Garage") which serves the Building:  Four Greenspoint Plaza.  No specific
spaces in the Garage are to be assigned to Tenant, but Landlord will issue to
Tenant the aforesaid number of parking permits, each of which will authorize
parking in the Garage of a vehicle on an unassigned basis.  Landlord may
designate the area within which each such vehicle may be parked, and Landlord
may change such designations from time to time.  Landlord may make, modify and
enforce reasonable rules and regulations relating to the parking of vehicles in
the Garage, and Tenant will abide by such rules and regulations.  From time to
time, Landlord may, without notice to Tenant, open visitor parking into areas
of the Garage designated for Tenant's parking spaces.

                 As the Basic Parking Charge, Tenant covenants and agrees to
pay Landlord during the Term, as Additional Rental hereunder, the sum of $40.00
per month, plus applicable sales tax thereon, for each of the parking permits
to be issued by Landlord as herein provided, such sum to be payable monthly in
advance on the first day of each and every calendar month during the Term, and
a pro rata portion of such sum shall be payable for any partial calendar month
during the Term commences on a date other than the first day of a calendar
month.  Tenant's obligation to pay the Parking Charge, and applicable sales tax
thereon, shall be considered an obligation to pay rent for all purposes
hereunder and shall be secured in like manner as is Tenant's obligation to pay
rent under the Lease.  Default in payment of any amounts due hereunder or
failure by Tenant to comply with the rules and regulations promulgated by
Landlord or the operator of the Garage shall be deemed a default under the
Lease.

         supervision of the Landlord and in the manner agreed between the
         tenant and Landlord by prearrangement before performance.  Such
         prearrangement initiated by a tenant will include after hours
         scheduling by Landlord, and subject to his reasonable decision and
         control, as to the exact time, method, and routing of movement and as
         to limitations for safety or other concern which may prohibit any
         article, equipment or any other item from being brought into the
         building.  The tenants are to assume all risks as to the damage to
         articles moved and injury to persons or public engaged or not engaged
         in such movement, including equipment, property and personnel of
         Landlord if damaged or injured as a result of an act in connection
         with carrying out this service for a tenant from time of entering

         service performed for a tenant.

8.       Landlord shall prescribe the weight and position of safes and other
         heavy equipment, which shall in all cases, to distribute weight, stand
         on supporting devices reasonably approved by Landlord.  All damages
         done to the building by taking in or putting out any property of a
         tenant, or done by a tenant's property while in the building, shall be
         repaired at the expense of such tenant.

9.       A tenant shall notify the building manager when safes or other heavy
         equipment are to be taken in or out of the building, and the moving
         shall be done under the supervision of the building manager, after
         written permit from the Landlord reasonably and timely issued.
         Persons employed to move such property must be acceptable to Landlord
         in Landlord's reasonable discretion.

10.      Corridor doors, when not in use, shall be kept closed.

11.      Each tenant shall cooperate with Landlord's employees in keeping its
         leased area neat and clean.  No tenant shall employ any person for the
         purpose of cleaning other than the building's cleaning and maintenance
         personnel without prior approval by Landlord.  Landlord shall be in no
         way responsible to the tenants, their agents, employees or invitees
         for any loss of property from the Premises or public areas or for any
         damages to any property therein from any cause whatsoever, other than
         due to the gross negligence or willful misconduct of Landlord, its
         agents and/or employees.

12.      To insure orderly operation of the building, no ice, mineral or water,
         towels, newspapers, etc. shall be delivered to any leased area except
         by persons appointed or approved by the Landlord in writing.

13.      Should a tenant require a telegraphic, telephonic, annunciator or
         other communication service, Landlord will direct the electricians
         where and how wires are to be introduced and placed and





                                      -2-
<PAGE>   43
         none shall be introduced or placed except as Landlord shall reasonably
         approve.  Electric current shall not be used for power or heating
         without Landlord's prior written permission.

         or otherwise interfere in any way with other tenants or persons having
         business with them.

         shafts or stairways.  No birds or animals (except seeing eye dogs)
         shall be brought into or kept in, on or about any tenant's area.

16.      No machinery of any kind other than normal office equipment shall be
         operated by any tenant on its leased area without the prior written
         consent of Landlord which consent shall not be unreasonably withheld,
         delayed, denied or conditioned, nor shall any tenant use, or keep in
         the building, any flammable or explosive fluid or substance, except in
         accordance with local fire codes and procedures approved by Landlord.

17.      No portion of any tenant's lease area shall at any time be used or
         occupied as sleeping or lodging quarters.

18.      Landlord will not be responsible for lost or stolen personal property,
         money or jewelry from tenant's leased area or public areas regardless
         of whether such loss occurs when area is locked against entry or not
         unless due to the gross negligence or willful misconduct of Landlord,
         its agents and/or employees.

19.      Tenant will not tamper with or attempt to adjust temperature control
         thermostats in the Premises.

         tenants for security of their premises as permitted by such tenants'
         leases or otherwise consented to by Landlord in writing.

21.      Landlord reserves the right to rescind any of these rules and

in control shall be deemed to have occurred if (i) any "person" (as such term
is used in Sections 13(d) and 14(d) of the Exchange Act) other than the

                          re-appoint the Executive to the offices of Chairman
                          of the Board, President and Chief Executive Officer
                          of the Employer or a material adverse change made by
                          the Employer in the Executive's functions, duties or
                          responsibilities as Chairman of the Board, President

                          Employer's current principal executive office, except
                          for required travel on business of the Employer to an
                          extent substantially consistent with the Executive's

                          Control;

Executive's employment by the Employer for any reason, including without
limitation for Cause, Disability or Retirement, or by the Executive for any
reason, including without limitation for Good Reason, shall be communicated by
a written "Notice of Termination" to the other party hereto.  For purposes of
this Agreement, a "Notice of Termination" shall mean a dated notice which (i)
indicates the specific termination provision in this Agreement relied upon,
(ii) sets forth in reasonable detail the facts and circumstances claimed to
provide a basis for termination of Executive's employment under the provision

         2.      TERM OF EMPLOYMENT.

Board, President and Chief Executive Officer, and Executive hereby accepts said
employment and agrees to render such services to the Employer, on the terms and
conditions set forth in this Agreement. Unless extended as provided in this
Section 2, this Agreement shall terminate five (5) years after the date first
above written; provided, however, this Agreement shall be automatically renewed
on its anniversary date ("Annual Renewal Date") each year for one (1)
additional year so that this Agreement shall continue in effect for a period
ending five (5) years from each Annual Renewal Date unless either party shall
give written notice of non-renewal, in accordance with Section 14 hereof to the
other party at least  thirty (30) days prior to an Annual Renewal Date, in
which event this Agreement shall continue in effect for a term ending on the
fifth consecutive Annual Renewal Date immediately following such notice.
Reference herein to the term of this Agreement shall refer both to the initial
term and any successive term as the context requires.

         (b)     During the term of this Agreement, the Executive shall perform
such executive services for the Employer as is consistent with his title of
President and Chief Executive Officer and as directed, from time to time, by
the Board of Directors, including but not limited to, the supervision of the

the term hereof (as defined in Section 2(a)), be employed or involved in any
other
<PAGE>   5
Blecker Employment Agreement

business activity, whether or not such activity is pursued for gain, profit or
other pecuniary advantage, except for (i) volunteer services for or on behalf
of such religious, educational, non-profit and/or other eleemosynary
organization as Executive may wish to serve, (ii) service as a director of as
many as three (3) for-profit business activities, and (iii) such other
activities as may be specifically approved by the Board of Directors (without
the Executive's participation or vote).  This restriction shall not, however,
preclude the Executive from employment in any capacity with affiliates of the
Corporation, nor shall any remuneration from such affiliates be considered in
calculating the Base Salary (as defined in Section 3(a)) due to Executive
hereunder.

         3.      COMPENSATION AND BENEFITS.

         (a)     For services rendered hereunder by the Executive, the Employer
shall compensate and pay Executive for his services during the term of this
Agreement at a minimum base salary of two hundred fifty thousand dollars
($250,000.00) per year ("Base Salary"), which may be increased from time to time
in such amounts as may be determined by the Board of Directors of the Employer.
In addition to his Base Salary, the Executive shall receive during the term of 
this Agreement such bonus payments as may be determined by the Board of
Directors of the Employer. In addition to any bonus paid or should the Board of
Directors not provide any bonus to Executive for any year, the Executive's 
Base Salary shall automatically be increased by the amount of the prior
year's increase in the "Consumer Price Index for all Urban Consumers
(1982-84=100), Washington, D.C. Area, All Items," as published by the United
States Department of Labor, Bureau of Labor Statistics (the "CPI").  With
respect to prior years, the Executive hereby agrees that the Corporation shall
not be required to pay to him any "basic annual compensation" (i.e., salary) in
excess of amounts actually paid in cash from the year 1981 to the date hereof.

         (b)     During the term of the Agreement, Executive shall be entitled
to participate in and receive the benefits of any pension or other retirement
benefit plan, the 401(k) plan, profit sharing, stock option, employee stock
ownership, or other plans, benefits and privileges given to employees and
executives of the Employer, to the extent commensurate with his then duties and
responsibilities, as fixed by the Board of Directors of the Employer.  The
Employer shall not make any changes in such plans, benefits or privileges which
would adversely affect Executive's rights or benefits thereunder, unless such
change occurs pursuant to a program applicable to all executive officers of the
Employer and does not result in a proportionately greater adverse change in the
rights of or benefits to Executive as compared with any other executive officer
of the Employer.  Nothing paid to Executive under any plan or arrangement
presently in effect or made available in the future shall be deemed to be in
lieu of the base salary payable to Executive pursuant to Section 3(a) hereof.

         (c)     During the term of this Agreement, Executive shall be entitled

established from time to time by the Board of Directors of the Employer.
Executive shall also be entitled to all paid holidays to which similarly
situated executives and key management employees of the Corporation are
entitled.  The Executive shall be entitled to paid leave due to physical
illness in each calendar year to be taken and determined in accordance with the
policies and procedures as established from time to time by the Board of
Directors.  Executive shall not be entitled to receive any additional
compensation from the Employer for failure to take a vacation, or failure to
use "sick days," nor shall Executive be able to accumulate unused vacation or
"sick" time from one year to the next, except to the extent authorized by the
Board of Directors of the Employer.

         (d)     The Corporation shall provide the Executive with secretarial
and support staff and furnished offices and conference facilities in Rockville,
Maryland, and in such other location, if any, in which the Executive hereafter
agrees to perform services on behalf of the Corporation, all of which shall be
consistent with the Executive's duties as the Chairman of the Board, President
and Chief Executive Officer of the Corporation and sufficient for the efficient
performance of those duties.  Nothing in this Agreement shall be construed to
require the Executive to perform or discharge his duties to the Corporation at
any office or location outside of Rockville, Maryland.

         4.      EXPENSES.  The Employer shall reimburse Executive or otherwise
provide for or pay for all reasonable expenses incurred by Executive in
furtherance of, or in connection with the business of the Employer, including,
but not by way of limitation, traveling expenses, and all reasonable
entertainment expenses (whether incurred at the Executive's residence, while
traveling or otherwise), subject to such reasonable documentation and other
limitations as may be established by the Board of Directors of the Employer.
The Employer shall furnish to the Executive a new leased automobile comparable
in class and style to Executive's current vehicle every three (3) years and
shall pay for all gas, oil, repairs, maintenance, insurance and other related
costs of such vehicle's operation.  If such expenses are paid in the first
instance by Executive, the Employer shall reimburse the Executive therefor.

         5.      TERMINATION.

         (a)     The Employer shall have the right, at any time upon prior
Notice of Termination, to terminate the Executive's employment hereunder for

         (b)     In the event that (i) Executive's employment is terminated by
the Employer for Cause or (ii) Executive terminates his employment hereunder
other than for Good Reason, Executive shall have no right pursuant to this
Agreement to compensation or other benefits for any period after the applicable
Date of Termination.

         (c)     In the event that (i) Executive's employment is terminated by
the Employer for other than Cause, including termination due to Disability,
Retirement or the Executive's death, or (ii) such employment is terminated by
the Executive due to a material breach of this Agreement by the Employer, which
breach has not been cured within fifteen (15) days after a written notice of
non-compliance has been given by the Executive to the Employer, then the
Employer shall, subject to the provisions of Section 6 hereof, if applicable,

                 (A)      Pay to the Executive, in a lump sum or in thirty-six
(36) equal monthly installments (at the Executive's option) beginning with the
first business day of the month following the Date of Termination, a cash
severance amount equal to three (3) times the Executive's Average Annual
Compensation, and

                 (B)      Maintain and provide for a period ending at the
earlier of (i) the expiration of the remaining term of employment pursuant
hereto prior to the Notice of Termination or (ii) the date of the Executive's

entitled under the terms of such employment to benefits substantially similar
to those described in this subparagraph (B)), at no cost to the Executive, the
Executive's continued participation in all group insurance, life insurance,
health and accident, disability and other employee benefit plans, programs and
arrangements in which the Executive was entitled to participate immediately
prior to the Date of Termination (other than stock option and restricted stock
plans of the Employer), provided that in the event that the Executive's
participation in any plan, program or arrangement as provided in this
subparagraph (B) is barred or during such period any such plan, program or
arrangement is discontinued or the benefits thereunder are materially reduced,
the Employer shall arrange to provide the Executive with benefits substantially
similar to those which the Executive was entitled to receive under such plans,
programs and arrangements immediately prior to the Date of Termination.

         (d)     In the event that Executive's employment is terminated by the
Executive for Good Reason subsequent to Change in Control, then the Employer
shall:

                 (A)      Pay to the Executive, in a lump sum payable within
five business days following the Date of Termination, a cash severance amount
equal to five (5) times the Executive's Average Annual Compensation, and

                 (B)      Maintain and provide for a period ending at the
earlier of (i) the expiration of the remaining term of employment pursuant
hereof prior to the Notice of Termination or (ii) the date of the Executive's
full-time employment by another employer (provided that the Executive is
entitled under the terms of such employment to benefits substantially similar
to those described in this subparagraph (B)), at no cost to the Executive, the
Executive's continued participation in all group insurance, life insurance,
health and accident, disability and other employee benefit plans, programs and

any plan, program or arrangement is discontinued or the benefit thereunder are
materially reduced, the Employer shall arrange to provide the Executive with
benefits substantially similar to those which the Executive was entitled to
receive under such plans, programs and arrangements immediately prior to the
Date of Termination.

         6.      ADDITIONAL BENEFITS UNDER CERTAIN CIRCUMSTANCES.

         (a)     If the Executive becomes liable, in any taxable year, for the
repayment of an excise tax under Section 4999 of the Code on account of any
payments to the Executive pursuant to Section 5, and the Employer chooses not
to contest the liability or has exhausted all administrative and judicial
appeals contesting the liability, the Employer shall pay the Executive (i) an
amount equal to the excise tax for which the Executive is liable under Section
4999 of the Code, (ii) the federal, state, and local income taxes, and interest
if any, for which the Executive is liable on account of the payments pursuant
to item (i), and (ii) any additional excise tax under Section 4999 of the Code
and any federal, state and local income taxes for which the Executive is liable
on account of payments made pursuant to items (i) and (ii).

         (b)     This Section 6(b) applies if the amount of payments to the
Executive under Section 6(a) has not been determined with finality by the
exhaustion of administrative and judicial appeals.  In such circumstances, the
Employer and the Executive shall, as soon as
<PAGE>   9
Blecker Employment Agreement
Page 9



practicable after the event or series of events have occurred giving rise to
the imposition of the excise tax, cooperate in determining the amount of the
Executive's excise tax liability for purposes of paying the estimated tax.  The
Executive shall thereafter furnish to the Employer or its successors a copy of
each tax return which reflects a liability for an excise tax under Section 4999
of the Code at least thirty (30) days before the date on which such return is
required to be filed with the IRS.  The liability reflected on such return
shall be dispositive for the purposes hereof unless, within twenty (20) days
after such notice is given, the Employer furnishes the Executive with a letter
of the auditors or tax advisor selected by the Employer indicating a different
liability or that the matter is not free from doubt under the applicable laws
and regulations and that the Executive may, in such auditor's or advisor's
opinion, cogently take a different position, which shall be set forth in the
letter with respect to the payments in question.  Such letter shall be
addressed to the Executive and state that he is entitled to rely thereon.  If
the Employer furnishes such a letter to the Executive, the position reflected
in such letter shall be dispositive for purposes of this Agreement, except as
provided in Section 6(c) below.

         (c)     Notwithstanding anything in this Agreement to the contrary, if
the Executive's liability for the excise tax under Section 4999 of the Code for
a taxable year is subsequently determined to be less than the amount paid by
the Employer pursuant to Section 6(a), the Executive shall repay the Employer
at the time that the amount of such excise tax liability is finally determined,
the portion of such income and excise tax payments attributable to the
reduction (plus interest on the amount of such repayment at the rate provided
on Section 1274(b)(2)(B) of the Code) and if the Executive's liability for the
excise tax under Section 4999 of the Code for a taxable year is subsequently
determined to exceed the amount paid by the Employer pursuant to Section 6(a),
the Employer shall make an additional payment of income and excise taxes in the
amount of such excess, as well as the amount of any penalty and interest
assessed with respect thereto at the time that the amount of such excess and
any penalty and interest is finally determined.

         7.      MITIGATION; EXCLUSIVITY OF BENEFITS.

         (a)     The Executive shall not be required to mitigate the amount of
any benefits hereunder by seeking other employment or otherwise, nor shall the
amount of any such benefits be reduced by any compensation earned by the
Executive as a result of employment by another employer after the Date of
Termination or otherwise.

         (b)     The specific arrangements referred to herein are not intended
to exclude any other benefits which may be available to the Executive upon a
termination of employment with the Employer pursuant to employee benefit plans
of the Employer or otherwise.
<PAGE>   10
Blecker Employment Agreement
Page 10



         8.      WITHHOLDING.  All payments required to be made by the Employer
hereunder to the Executive shall be subject to the withholding of such amounts,
if any, relating to tax and other payroll deductions as the Employer may
reasonably determine should be withheld pursuant to any applicable law or
regulation.

         9.      NON-SOLICITATION OF CUSTOMERS AND EMPLOYEES.

         (a)     The Executive hereby acknowledges and recognizes the highly
competitive nature of the business of the Corporation and accordingly agrees
that, during the term of this Agreement and, in consideration of the receipt of
any payment pursuant to this Agreement, for a period of two years following the
date of termination of the Executive's employment under this Agreement, unless
otherwise agreed to in writing by the Corporation, the Executive shall not,
either directly or indirectly, in any manner or capacity, whether as principal,
agent, partner, officer, director, employee, joint venturer, salesman, or
corporate shareholder or otherwise for the benefit of any Person (as defined
below), (i) render services to, or solicit the rendering of services to, any
Person in competition with the business of the Corporation, which then is, or
at any time during a period of one year prior to the termination of the
Executive's employment under this Agreement (the "Termination Date"), was a
Customer (as defined below) of the Corporation, or (ii) solicit the rendering
of services to any Person of any kind whatsoever which is then or has been at
any time during a period of one year prior to the Termination Date a Customer,
employee, salesperson, agent or representative of the Corporation in any manner
which interferes or might interfere with the relationship of the Corporation
with such Person, or in an effort to obtain such Person as a customer,
supplier, employee, salesperson, agent or representative of any business in
competition with the Corporation, or (iii) for a period of two years following
the Termination Date, hire or participate in the hiring by any Person of an
employee of the Corporation.  In order to assure strict compliance with the
foregoing, and in recognition of the compensation to be paid by Employer to
Executive on the termination of this Agreement, Executive grants to Employer
the sole and absolute right to determine whether any employment or services
anticipated to be undertaken by Executive during said period of time as
outlined above, is or may be in violation of the foregoing provisions and
Executive agrees to notify Employer, in writing, fourteen (14) days prior to
undertaking any employment or services within the said time period, regardless
of the nature thereof, of the name and address of any such intended employer,
proposed job title, proposed job description and salary, and the business of
the prospective employer.  If, within such fourteen (14) day period, Employer
shall object on reasonable grounds to such anticipated employment in writing to
Executive, Executive agrees not to accept the same or in any manner directly or
indirectly render services to any such prospective employer.

         "Person" means any individual, trust, partnership, corporation,
limited liability company, association, or other legal entity.
<PAGE>   11
Blecker Employment Agreement
Page 11




         "Customer" means any Person with which the Corporation or any
subsidiary is currently engaged to provide goods or services, has been engaged
to provide goods or services within twelve (12) months prior to the Termination
Date, or actively marketed, discussed a project with, negotiated with, provided
a bid to or otherwise communicated with in an effort to obtain an engagement to
provide goods or services sold by the Corporation or any subsidiary within
twelve (12) months prior to the Termination Date.

         (b)     It is expressly understood and agreed that although the
Executive and the Corporation consider the restrictions contained in Section
9(a) of this Agreement reasonable for the purpose of preserving for the
Corporation its good will and other proprietary rights, if a final judicial
determination is made by a court having jurisdiction that the time or territory
or any other restriction contained in Section 9(a) of this Agreement is an
unreasonable or otherwise unenforceable restriction against the Executive, the
provisions of Section 9(a) of this Agreement shall not be rendered void but
shall be deemed amended to apply as to such maximum time and territory and to
such other extent as such court may judicially determine or indicate to be
reasonable.

         10.     DISCLOSURE OF CONFIDENTIAL INFORMATION.  The Executive
acknowledges that the Corporation's trade secrets, as they may exist from time
to time, and confidential information concerning its products, programs,
technical information, procurement and sales activities and procedures,
identity of customers and potential customers, business plans, promotion and
pricing techniques, and credit and financial data concerning customers are
valuable, special and unique assets of the Corporation.  In light of the highly
competitive nature of the industry in which the Corporation's business is
conducted, the Executive agrees that all knowledge and information described in
the preceding sentence not in the public domain and heretofore or in the future
obtained by the Executive shall be considered confidential information.
Executive agrees that he will not disclose any or such secrets, processes or
information to any Person or other entity for any reason or purpose whatsoever,
except as necessary in the performance of his duties as an employee of or
consultant to the Corporation and then only upon a written confidentiality
agreement in such form and content as requested by the Corporation from time to
time, nor shall the Executive make use of any such secrets, processes or
information (other than information in the public domain) for his own purposes
or for the benefit of himself, any Person or other entity (except the Company
and its subsidiaries) under any circumstances.  The provisions contained in
this Section 10 shall also apply to information obtained by the Executive with
respect to any future subsidiary of the Corporation.

and any other property of the Corporation within the possession or under the
control of Executive (or, as appropriate, his personal representatives) and
relating to the affairs and business of the Corporation, whether drafted,
created or compiled by Executive or received by Executive from other
individuals or entities (whether employees of or affiliated with the
Corporation).

         12.     REMEDIES.  The Executive acknowledges and agrees that the
Company's remedy at law for a breach or threatened breach of any of the
provisions of Section 9, Section 10 or Section 11 of this Agreement would be
inadequate and, in recognition of this fact, in the event of a breach or
threatened breach by the Executive of any of the provisions of Section 9,
Section 10 or Section 11 of this Agreement, it is agreed that, in addition to
any remedy at law, the Corporation shall be entitled to without posting any
bond, and the Executive agrees not to oppose the Corporation's request in the
nature of specific performance, temporary restraining order, temporary or
permanent injunction, or any other equitable relief or remedy which may then be
available, provided, however, nothing herein shall be deemed to relieve the
Corporation of its burden to prove grounds warranting such relief nor preclude
the Executive from contesting such grounds or facts in support thereof.
Nothing herein contained shall be construed as prohibiting the Corporation from
pursuing any other remedies available to it for such breach or threatened
breach.

         13.     ASSIGNABILITY.  The Employer shall assign this Agreement and
its rights and obligations hereunder in whole, but not in part, to any
corporation or other entity with or into which the Employer may hereafter merge
or consolidate or to which the Employer may transfer all or substantially all of
its assets, if in any such case said corporation or other entity shall by
operation of law or expressly in writing assume all obligations of the Employer
hereunder as fully as if it had been originally made a party hereto, but may not
otherwise assign this Agreement or its rights and obligations hereunder. The
Executive may not assign or transfer this Agreement or any rights or obligations
hereunder.

         14.     NOTICE.  For the purposes of this Agreement, notices and all

         15.     AMENDMENT; WAIVER.  This Agreement supersedes and replaces the
Contract of Employment by and between the Executive and the Employer dated
August 1, 1981, which shall be, upon the execution of this Agreement,
terminated, null and void as of the date hereof.  This Agreement represents the
entire agreement of the parties relating to subject matter hereof.  No
provisions of this Agreement may be modified, waived or discharged unless such
waiver, modification or discharge is agreed to in writing signed by the
Executive and such officer or officers as may be specifically designated by the
Board of Directors of the Employer to sign on its behalf.  No waiver by any
party hereto at any time of any breach by any other party hereto of, or
compliance with, any condition or provision of this Agreement to be performed
by such other party shall be deemed a waiver of similar or dissimilar
provisions or conditions at the same or at any prior or subsequent time.

         16.     GOVERNING LAW.  The validity, interpretation, construction and
performance of this Agreement shall be governed by the laws of the State of
Maryland.

         17.     NATURE OF OBLIGATIONS.  The obligations of the Employer
hereunder are unsecured and the Executive represents a general creditor of the
Corporation for compensation which may be due and owing.  Nothing contained
herein shall create or require the Employer to create a trust of any kind to
fund any benefits which may be payable hereunder, and to the extent that the
Executive acquires a right to receive benefits from the Employer hereunder,
such right shall be no greater than the right of any unsecured general creditor
of the Employer.

         18.     INTERPRETATION AND HEADINGS.  This Agreement shall be
interpreted in order to achieve the purposes for which it was entered into.
The section headings contained in this Agreement are for reference purposes
only and shall not affect in any way the meaning or interpretation of this
Agreement.

         19.     SEVERABILITY.  The invalidity or unenforceability of any
provision of this Agreement shall not affect the validity or enforceability of
any other provisions of this Agreement, which shall remain in full force and
effect.  With respect to Section 9 of this Agreement, in the event any court of
competent jurisdiction determines that such provisions are unreasonable or
contrary to law with respect to their time or geographic restriction, or both,
the parties hereto authorize such court to substitute restrictions as it deems
appropriate without invalidating such paragraph or this Agreement.

         20.     COUNTERPARTS.  This Agreement may be executed in one or more
counterparts, each of which shall be deemed to be an original but all of which
together will constitute one and the same instrument.

         IN WITNESS WHEREOF, this Agreement has been executed as of the date
first above written.

                                   WITNESSETH

         WHEREAS, the Executive is presently the Executive Vice President of the

the Employer and in consideration of the Executive's agreement to remain in the
employ of the Employer pursuant to the terms and conditions hereof, the parties
desire to specify the terms and conditions of Executive's continuing employment
with the Corporation and to provide certain severance benefits which shall be

         NOW THEREFORE, in consideration of the premises and the mutual
agreements herein contained, the parties hereto, intending to be legally bound,
hereby agree as follows:

in control shall be deemed to have occurred if (i) any "person" (as such term

in Rule 13d-3 under the Exchange Act), directly or indirectly, of securities of
the Corporation representing 25% or more of the combined voting power of the
Corporation's then outstanding securities; or (ii) during any period of twenty
four consecutive months, individuals who at the beginning of such period

employment for "Good Reason" shall mean termination by the Executive following

                          re-appoint the Executive to the office of Executive
                          Vice President of the Employer or a material adverse
                          change made by the Employer in the Executive's
                          functions, duties or responsibilities as
                          Executive Vice President of the Employer;

                          time or, except to the extent permitted by Section
                          3(b) hereof, a material reduction in the package of
                          fringe benefits provided to the Executive, taken as a
                          whole;

                          Employer's current principal executive office, except
                          for required travel on business of the Employer to an
                          extent substantially consistent with the Executive's
                          business travel obligations prior to the Change in
                          Control;

         2.      TERM OF EMPLOYMENT.

render such services to the Employer, on the terms and conditions set forth in
this Agreement. Unless extended as provided in this Section 2, this Agreement
shall terminate five (5) years after the date first above written; provided,
however, this Agreement shall be automatically renewed on its anniversary date
("Annual Renewal Date") each year for one (1) additional year so that this
Agreement shall continue in effect for a period ending five (5) years from each
Annual Renewal Date unless either party shall give written notice of
non-renewal, in accordance with Section 14 hereof to the other party at least
thirty (30) days prior to an Annual Renewal Date, in which event this Agreement
shall continue in effect for a term  ending on the fifth consecutive Annual
Renewal Date immediately following such notice.  Reference herein to the term
of this Agreement shall refer both to the initial term and any successive term
as the context requires.

         (b)     During the term of this Agreement, the Executive shall perform
such executive services for the Employer as is consistent with his title of
Executive Vice President and as directed, from time to time, by the Board of
Directors and/or the President and Chief Executive Officer, including but not
limited to, the supervision of the Corporation's business development,
marketing and sales operations.  The Executive shall devote his full time,
attention and energies to the business of the Corporation and shall not, during
the term hereof (as defined in Section 2(a)), be employed or involved in any
other business activity, whether or not such activity is pursued for gain,

Corporation, nor shall any remuneration from such affiliates
<PAGE>   5
Geritz Employment Agreement
Page 5

be considered in calculating the Base Salary (as defined in Section 3(a)) due
to Executive hereunder.

         3.      COMPENSATION AND BENEFITS.

         (a)     For services rendered hereunder by the Executive, the Employer
shall compensate and pay Executive for his services during the term of
this Agreement at a minimum base salary of one hundred twenty-five thousand
dollars ($125,000.00) per year ("Base Salary"), which may be increased from
time to time in such amounts as may be determined by the Board of Directors of
the Employer. In addition to his Base Salary, the Executive shall receive a
cash bonus for fiscal 1998, payable in May 1998 (on a date in May 1998
determined by management) in the amount of one hundred twenty-five thousand
dollars ($125,000.00) and a cash bonus for the fiscal years 1999, 2000 and 2001 
to be based upon performance objectives to be determined by and between the
Board of Directors (or the Compensation Committee thereof) and the Executive
prior to the commencement of each such fiscal year, using quarterly goals and
based upon targeted revenue and earnings growth of the Corporation, strategic
alliances or acquisitions and the Executive's management of the Corporation's
affairs, payable quarterly throughout the fiscal year, provided that the goals
are successfully attained. In addition to any bonus paid or should the Board of
Directors not provide any bonus to Executive for any year, the Executive's 
Base Salary shall automatically be increased by the amount of the prior
year's increase in the "Consumer Price Index for all Urban Consumers
(1982-84=100), Washington, D.C. Area, All Items," as published by the United
States Department of Labor, Bureau of Labor Statistics (the "CPI").  

         (b)     During the term of the Agreement, Executive shall be entitled
to participate in and receive the benefits of any pension or other retirement
benefit plan, the 401(k) plan, profit sharing, stock option, employee stock
ownership, or other plans, benefits and privileges given to employees and
executives of the Employer, to the extent commensurate with his then duties and
responsibilities, as fixed by the Board of Directors of the Employer.  The
Employer shall not make any changes in such plans, benefits or privileges which
would adversely affect Executive's rights or benefits thereunder, unless such
change occurs pursuant to a program applicable to all executive officers of the
Employer and does not result in a proportionately greater adverse change in the
rights of or benefits to Executive as compared with any other executive officer
of the Employer.  Nothing paid to Executive under any plan or arrangement
presently in effect or made available in the future shall be deemed to be in
lieu of the base salary payable to Executive pursuant to Section 3(a) hereof.

         (c)     During the term of this Agreement, Executive shall be entitled
to four (4) weeks (20 working days) paid vacation in each calendar year to be
taken and determined in accordance with the vacation policies and procedures as
established from time to time
<PAGE>   6
Geritz Employment Agreement
Page 6

by the Board of Directors of the Employer.  Executive shall also be entitled to
all paid holidays to which similarly situated executives and key management
employees of the Corporation are entitled.  The Executive shall be entitled to
paid leave due to physical illness in each calendar year to be taken and
determined in accordance with the policies and procedures as established from
time to time by the Board of Directors.  Executive shall not be entitled to
receive any additional compensation from the Employer for failure to take a
vacation, or failure to use "sick days," nor shall Executive be able to
accumulate unused vacation or "sick" time from one year to the next, except to
the extent authorized by the Board of Directors of the Employer.

         4.      EXPENSES.  The Employer shall reimburse Executive or otherwise
provide for or pay for all reasonable expenses incurred by Executive in
furtherance of, or in connection with the business of the Employer, including,
but not by way of limitation, traveling expenses, and all reasonable
entertainment expenses (whether incurred at the Executive's residence, while
traveling or otherwise), subject to such reasonable documentation and other
limitations as may be established by the Board of Directors of the Employer.
If such expenses are paid in the first instance by Executive, the Employer
shall reimburse the Executive therefor.

         5.      TERMINATION.

         (a)     The Employer shall have the right, at any time upon prior
Notice of Termination, to terminate the Executive's employment hereunder for
any reason, including without limitation termination for Cause, Disability or
Retirement, and Executive shall have the right, upon prior Notice of
Termination, to terminate his employment hereunder for any reason.

         (b)     In the event that (i) Executive's employment is terminated by
the Employer for Cause or (ii) Executive terminates his employment hereunder
other than for Good Reason, Executive shall have no right pursuant to this
Agreement to compensation or other benefits for any period after the applicable
Date of Termination.

         (c)     In the event that (i) Executive's employment is terminated by
the Employer for other than Cause, including termination due to Disability,
Retirement or the Executive's death, or (ii) such employment is terminated by
the Executive due to a material breach of this Agreement by the Employer, which
breach has not been cured within fifteen (15) days after a written notice of
non-compliance has been given by the Executive to the Employer, then the
Employer shall, subject to the provisions of Section 6 hereof, if applicable,

                 (A)      Pay to the Executive, in a lump sum or in thirty-six

                 (B)      Maintain and provide for a period ending at the
earlier of (i) the expiration of the remaining term of employment pursuant
hereto prior to the Notice of Termination or (ii) the date of the Executive's
full-time employment by another employer (provided that the Executive is
entitled under the terms of such employment to benefits substantially similar
to those described in this subparagraph (B)), at no cost to the Executive, the
Executive's continued participation in all group insurance, life insurance,
health and accident, disability and other employee benefit plans, programs and
arrangements in which the Executive was entitled to participate immediately
prior to the Date of Termination (other than stock option and restricted stock
plans of the Employer), provided that in the event that the Executive's
participation in any plan, program or arrangement as provided in this
subparagraph (B) is barred or during such period any such plan, program or
arrangement is discontinued or the benefits thereunder are materially reduced,
the Employer shall arrange to provide the Executive with benefits substantially
similar to those which the Executive was entitled to receive under such plans,
programs and arrangements immediately prior to the Date of Termination.

         (d)     In the event that Executive's employment is terminated by the
Executive for Good Reason subsequent to Change in Control, then the Employer
shall:

                 (A)      Pay to the Executive, in a lump sum payable within
five business days following the Date of Termination, a cash severance amount
equal to five (5) times the Executive's Average Annual Compensation, and

                 (B)      Maintain and provide for a period ending at the
earlier of (i) the expiration of the remaining term of employment pursuant
hereof prior to the Notice of Termination or (ii) the date of the Executive's
full-time employment by another employer (provided that the Executive is
entitled under the terms of such employment to benefits substantially similar
to those described in this subparagraph (B)), at no cost to the Executive, the
Executive's continued participation in all group insurance, life insurance,
health and accident, disability and other employee benefit plans, programs and
arrangements in which the Executive was entitled to participate immediately
prior to the Date of Termination (other than stock option and restricted stock
plans of Employer), provided that in the event the Executive's participation in
any plan, program or arrangement is discontinued or the benefit thereunder are
materially reduced, the Employer shall arrange to provide the Executive with
benefits substantially similar to those which the Executive was entitled to
receive under such plans, programs and arrangements immediately prior to the
Date of Termination.

         6.      ADDITIONAL BENEFITS UNDER CERTAIN CIRCUMSTANCES.

         (a)     If the Executive becomes liable, in any taxable year, for the
repayment of an excise tax under Section 4999 of the Code on account of any
payments to the Executive pursuant to Section 5, and the Employer chooses not
to contest the liability or has exhausted
<PAGE>   8
Geritz Employment Agreement
Page 8

all administrative and judicial appeals contesting the liability, the Employer
shall pay the Executive (i) an amount equal to the excise tax for which the
Executive is liable under Section 4999 of the Code, (ii) the federal, state,
and local income taxes, and interest if any, for which the Executive is liable
on account of the payments pursuant to item (i), and (ii) any additional excise
tax under Section 4999 of the Code and any federal, state and local income
taxes for which the Executive is liable on account of payments made pursuant to
items (i) and (ii).

         (b)     This Section 6(b) applies if the amount of payments to the
Executive under Section 6(a) has not been determined with finality by the
exhaustion of administrative and judicial appeals.  In such circumstances, the
Employer and the Executive shall, as soon as practicable after the event or
series of events have occurred giving rise to the imposition of the excise tax,
cooperate in determining the amount of the Executive's excise tax liability for
purposes of paying the estimated tax.  The Executive shall thereafter furnish
to the Employer or its successors a copy of each tax return which reflects a
liability for an excise tax under Section 4999 of the Code at least thirty (30)
days before the date on which such return is required to be filed with the IRS.
The liability reflected on such return shall be dispositive for the purposes
hereof unless, within twenty (20) days after such notice is given, the Employer
furnishes the Executive with a letter of the auditors or tax advisor selected
by the Employer indicating a different liability or that the matter is not free
from doubt under the applicable laws and regulations and that the Executive
may, in such auditor's or advisor's opinion, cogently take a different
position, which shall be set forth in the letter with respect to the payments
in question.  Such letter shall be addressed to the Executive and state that he
is entitled to rely thereon.  If the Employer furnishes such a letter to the
Executive, the position reflected in such letter shall be dispositive for
purposes of this Agreement, except as provided in Section 6(c) below.

         (c)     Notwithstanding anything in this Agreement to the contrary, if
the Executive's liability for the excise tax under Section 4999 of the Code for
a taxable year is subsequently determined to be less than the amount paid by
the Employer pursuant to Section 6(a), the Executive shall repay the Employer
at the time that the amount of such excise tax liability is finally determined,
the portion of such income and excise tax payments attributable to the
reduction (plus interest on the amount of such repayment at the rate provided
on Section 1274(b)(2)(B) of the Code) and if the Executive's liability for the
excise tax under Section 4999 of the Code for a taxable year is subsequently
determined to exceed the amount paid by the Employer pursuant to Section 6(a),
the Employer shall make an additional payment of income and excise taxes in the
amount of such excess, as well as the amount of any penalty and interest
assessed with respect thereto at the time that the amount of such excess and
any penalty and interest is finally determined.

         7.      MITIGATION; EXCLUSIVITY OF BENEFITS.

         (a)     The Executive shall not be required to mitigate the amount of
any benefits hereunder by seeking other employment or otherwise, nor shall the
amount of any such benefits be reduced by any compensation earned by the
Executive as a result of employment by another employer after the Date of
Termination or otherwise.

         (b)     The specific arrangements referred to herein are not intended
to exclude any other benefits which may be available to the Executive upon a
termination of employment with the Employer pursuant to employee benefit plans
of the Employer or otherwise.

         8.      WITHHOLDING.  All payments required to be made by the Employer
hereunder to the Executive shall be subject to the withholding of such amounts,
if any, relating to tax and other payroll deductions as the Employer may
reasonably determine should be withheld pursuant to any applicable law or
regulation.

         9.      NON-SOLICITATION OF CUSTOMERS AND EMPLOYEES.

         (a)     The Executive hereby acknowledges and recognizes the highly
competitive nature of the business of the Corporation and accordingly agrees
that, during the term of this Agreement and, in consideration of the receipt of
any payment pursuant to this Agreement, for a period of two years following the
date of termination of the Executive's employment under this Agreement, unless
otherwise agreed to in writing by the Corporation, the Executive shall not,
either directly or indirectly, in any manner or capacity, whether as principal,
agent, partner, officer, director, employee, joint venturer, salesman, or
corporate shareholder or otherwise for the benefit of any Person (as defined
below), (i) render services to, or solicit the rendering of services to, any
Person in competition with the business of the Corporation, which then is, or
at any time during a period of one year prior to the termination of the
Executive's employment under this Agreement (the "Termination Date"), was a
Customer (as defined below) of the Corporation, or (ii) solicit the rendering
of services to any Person of any kind whatsoever which is then or has been at
any time during a period of one year prior to the Termination Date a Customer,
employee, salesperson, agent or representative of the Corporation in any manner
which interferes or might interfere with the relationship of the Corporation
with such Person, or in an effort to obtain such Person as a customer,
supplier, employee, salesperson, agent or representative of any business in
competition with the Corporation, or (iii) for a period of two years following
the Termination Date, hire or participate in the hiring by any Person of an
employee of the Corporation.  In order to assure strict compliance with the
foregoing, and in recognition of the compensation to be paid by Employer to
Executive on the termination of this Agreement, Executive grants to Employer
the sole and absolute right to determine whether any employment or services
anticipated to be undertaken by Executive during said period of time as
outlined above, is or may be in violation of the foregoing provisions and
Executive agrees to notify Employer, in writing, fourteen (14) days prior to
undertaking any
<PAGE>   10
Geritz Employment Agreement
Page 10

employment or services within the said time period, regardless of the nature
thereof, of the name and address of any such intended employer, proposed job
title, proposed job description and salary, and the business of the prospective
employer.  If, within such fourteen (14) day period, Employer shall object on
reasonable grounds to such anticipated employment in writing to Executive,
Executive agrees not to accept the same or in any manner directly or indirectly
render services to any such prospective employer.

         "Person" means any individual, trust, partnership, corporation,
limited liability company, association, or other legal entity.

         "Customer" means any Person with which the Corporation or any
subsidiary is currently engaged to provide goods or services, has been engaged
to provide goods or services within twelve (12) months prior to the Termination
Date, or actively marketed, discussed a project with, negotiated with, provided
a bid to or otherwise communicated with in an effort to obtain an engagement to
provide goods or services sold by the Corporation or any subsidiary within
twelve (12) months prior to the Termination Date.

         (b)     It is expressly understood and agreed that although the
Executive and the Corporation consider the restrictions contained in Section
9(a) of this Agreement reasonable for the purpose of preserving for the
Corporation its good will and other proprietary rights, if a final judicial
determination is made by a court having jurisdiction that the time or territory
or any other restriction contained in Section 9(a) of this Agreement is an
unreasonable or otherwise unenforceable restriction against the Executive, the
provisions of Section 9(a) of this Agreement shall not be rendered void but
shall be deemed amended to apply as to such maximum time and territory and to
such other extent as such court may judicially determine or indicate to be
reasonable.

         10.     DISCLOSURE OF CONFIDENTIAL INFORMATION.  The Executive
acknowledges that the Corporation's trade secrets, as they may exist from time
to time, and confidential information concerning its products, programs,
technical information, procurement and sales activities and procedures,
identity of customers and potential customers, business plans, promotion and
pricing techniques, and credit and financial data concerning customers are
valuable, special and unique assets of the Corporation.  In light of the highly
competitive nature of the industry in which the Corporation's business is
conducted, the Executive agrees that all knowledge and information described in
the preceding sentence not in the public domain and heretofore or in the future
obtained by the Executive shall be considered confidential information.
Executive agrees that he will not disclose any or such secrets, processes or
information to any Person or other entity for any reason or purpose whatsoever,
except as necessary in the performance of his duties as an employee of or
consultant to the Corporation and then only upon a written confidentiality
agreement in such form and content as requested by the Corporation from time to
time, nor shall the Executive make use of any such secrets, processes or
information (other than information in the public domain) for his own purposes
or for the benefit of himself, any Person or other
<PAGE>   11
Geritz Employment Agreement
Page 11

entity (except the Company and its subsidiaries) under any circumstances.  The
provisions contained in this Section 10 shall also apply to information
obtained by the Executive with respect to any future subsidiary of the
Corporation.

         11.     BUSINESS INFORMATION.  Upon the termination of his employment
with the Corporation, Executive (or, as appropriate, his personal
representatives) shall deliver to the Corporation (without retaining copies of
the same), all plans, source codes, designs, customer lists, correspondence,
records, documents, accounts and papers of any description and any other
property of the Corporation within the possession or under the control of
Executive (or, as appropriate, his personal representatives) and relating to
the affairs and business of the Corporation, whether drafted, created or
compiled by Executive or received by Executive from other individuals or
entities (whether employees of or affiliated with the Corporation).

         12.     REMEDIES.  The Executive acknowledges and agrees that the
Company's remedy at law for a breach or threatened breach of any of the
provisions of Section 9, Section 10 or Section 11 of this Agreement would be
inadequate and, in recognition of this fact, in the event of a breach or
threatened breach by the Executive of any of the provisions of Section 9,
Section 10 or Section 11 of this Agreement, it is agreed that, in addition to
any remedy at law, the Corporation shall be entitled to without posting any
bond, and the Executive agrees not to oppose the Corporation's request in the
nature of specific performance, temporary restraining order, temporary or
permanent injunction, or any other equitable relief or remedy which may then be
available, provided, however, nothing herein shall be deemed to relieve the
Corporation of its burden to prove grounds warranting such relief nor preclude
the Executive from contesting such grounds or facts in support thereof.
Nothing herein contained shall be construed as prohibiting the Corporation form
pursuing any other remedies available to it for such breach or threatened
breach.

         13.     ASSIGNABILITY.  The Employer may assign this Agreement and its
rights and obligations hereunder in whole, but not in part, to any corporation
or other entity with or into which the Employer may hereafter merge or
consolidate or to which the Employer may transfer all or substantially all of
its assets, if in any such case said corporation or other entity shall by
operation of law or expressly in writing assume all obligations of the Employer
hereunder as fully as if it had been originally made a party hereto, but may
not otherwise assign this Agreement or its rights and obligations hereunder.
The Executive may not assign or transfer this Agreement or any rights or
obligations hereunder.

         14.     NOTICE.  For the purposes of this Agreement, notices and all
other communications provided for in this Agreement shall be in writing and
shall be deemed to have been duly given when delivered or mailed by certified
or registered mail, return receipt requested, postage prepaid, addressed to the
respective addresses set forth below:

         15.     AMENDMENT; WAIVER.  This Agreement supersedes and replaces the
Contract of Employment by and between the Executive and the Employer dated
August 1, 1981, which shall be, upon the execution of this Agreement,
terminated, null and void as of the date hereof.  This Agreement represents the
entire agreement of the parties relating to subject matter hereof.  No
provisions of this Agreement may be modified, waived or discharged unless such
waiver, modification or discharge is agreed to in writing signed by the
Executive and such officer or officers as may be specifically designated by the
Board of Directors of the Employer to sign on its behalf.  No waiver by any
party hereto at any time of any breach by any other party hereto of, or
compliance with, any condition or provision of this Agreement to be performed
by such other party shall be deemed a waiver of similar or dissimilar
provisions or conditions at the same or at any prior or subsequent time.

         16.     GOVERNING LAW.  The validity, interpretation, construction and
performance of this Agreement shall be governed by the laws of the State of
Maryland.

         17.     NATURE OF OBLIGATIONS.  The obligations of the Employer
hereunder are unsecured and the Executive represents a general creditor of the
Corporation for compensation which may be due and owing.  Nothing contained
herein shall create or require the Employer to create a trust of any kind to
fund any benefits which may be
<PAGE>   13
Geritz Employment Agreement
Page 13

payable hereunder, and to the extent that the Executive acquires a right to
receive benefits from the Employer hereunder, such right shall be no greater
than the right of any unsecured general creditor of the Employer.

         18.     INTERPRETATION AND HEADINGS.  This Agreement shall be
interpreted in order to achieve the purposes for which it was entered into.
The section headings contained in this Agreement are for reference purposes
only and shall not affect in any way the meaning or interpretation of this
Agreement.

         19.     SEVERABILITY.  The invalidity or unenforceability of any
provision of this Agreement shall not affect the validity or enforceability of
any other provisions of this Agreement, which shall remain in full force and
effect.  With respect to Section 9 of this Agreement, in the event any court of
competent jurisdiction determines that such provisions are unreasonable or
contrary to law with respect to their time or geographic restriction, or both,
the parties hereto authorize such court to substitute restrictions as it deems
appropriate without invalidating such paragraph or this Agreement.

         20.     COUNTERPARTS.  This Agreement may be executed in one or more
counterparts, each of which shall be deemed to be an original but all of which
together will constitute one and the same instrument.

         IN WITNESS WHEREOF, this Agreement has been executed as of the date
first above written.

                           ADMINISTRATION OF THE PLAN

       4.01   DUTIES OF THE COMMITTEE.  The Plan shall be administered and
interpreted by the Committee, as appointed from time to time by the Board
pursuant to Section 4.02.  The Committee shall have the authority to adopt,
amend and rescind such rules, regulations and procedures as, in its opinion,
may be advisable in the administration of the Plan, including, without
limitation, rules, regulations and procedures which (i) deal with satisfaction
of an Optionee's tax withholding obligation pursuant to Section 12.02 hereof,
(ii) include arrangements to facilitate the Optionee's ability to borrow funds
for payment of the exercise or purchase price of an Award, if applicable, from
securities brokers and dealers, and (iii) include arrangements which provide
for the payment of some or all of such exercise or purchase price by delivery
of previously-owned shares of Common Stock or other property and/or by
withholding some of the shares of Common Stock which are being acquired.  The
interpretation and construction by the Committee of any provisions of the Plan,
any rule, regulation or procedure adopted by it pursuant thereto or of any
Award shall be final and binding in the absence of action by the Board.

       4.02   APPOINTMENT AND OPERATION OF THE COMMITTEE.  The members of the
Committee shall be appointed by, and will serve at the pleasure of, the Board.
The Board from time to time may remove members from, or add members to, the

members of the Board, each of whom shall be a Non-Employee Director, as defined
in Rule 16b-3(b)(3)(i) of the Exchange Act or any successor thereto.  In
addition, each member of the Committee shall be an "outside director" within

provisions and limitations of the Plan, the Committee may adopt such rules,
regulations and procedures as it deems appropriate for the conduct of its
affairs.  It may appoint one of its members to be chairman and any person,
whether or not a member, to be its secretary or agent.  The Committee shall
report its actions and decisions to the Board at appropriate times but in no
event less than one time per calendar year.

       4.03   REVOCATION FOR MISCONDUCT.  The Board or the Committee may by
resolution immediately revoke, rescind and terminate any Option, or portion
thereof, to the extent not yet vested, previously granted or awarded under this
Plan to an Employee who is discharged from the employ of the Corporation or a
Subsidiary Company for cause, which, for purposes hereof, shall mean
termination because of the Employee's personal dishonesty, incompetence,
willful misconduct, breach of fiduciary duty involving personal profit,
intentional failure to perform stated duties, willful violation of any law,
rule, or regulation (other than traffic violations or similar offenses) or
final cease-and-desist order.  Options granted to a Non-Employee Director who
is removed for cause pursuant to the Corporation's Articles of Incorporation
and Bylaws shall terminate as of the effective date of such removal.

       4.04   LIMITATION ON LIABILITY.  Neither the members of the Board nor
any member of the Committee shall be liable for any action or determination
made in good faith with respect to the Plan, any rule, regulation or procedure
adopted by it pursuant thereto or any Awards granted under it in accordance
with the provisions of the Articles of Incorporation of the Corporation.  If a
member of the Board or the Committee is a party or is threatened to be made a
party to any threatened, pending or completed action, suit or proceeding,
whether civil, criminal, administrative or investigative, by reason of anything
done or not done by him in such capacity under or with respect to the Plan, the
Corporation shall, subject to the requirements of the Corporation's Articles of
Incorporation and/or Bylaws and of applicable laws and regulations, indemnify
such member against all liabilities and expenses (including attorneys' 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 the best
interests of the Corporation and/or its Subsidiary Companies and, with respect
to any criminal action or proceeding, had no reasonable cause to believe his
conduct was unlawful.

       4.05   COMPLIANCE WITH LAW AND REGULATIONS.  All Awards granted
hereunder shall be subject to all applicable federal and state laws, rules and
regulations and to such approvals by any government or regulatory agency as may
be required.  The Corporation shall not be required to issue or deliver any
certificates for shares of Common Stock prior to the completion of any
registration or qualification of or obtaining of consents or approvals with
respect to such shares under any federal or state law or any rule or regulation
of any government body, which the Corporation shall, in its sole discretion,
determine to be necessary or advisable.  Moreover, no Option may be exercised
if such exercise would be contrary to applicable laws and regulations.

       4.06   RESTRICTIONS ON TRANSFER.  The Corporation may place a legend
upon any certificate representing shares acquired pursuant to an Award granted
hereunder noting that the transfer of such shares may be restricted by
applicable laws and regulations.

                        COMMON STOCK COVERED BY THE PLAN

       6.01   OPTION SHARES.  The aggregate number of shares of Common Stock
which may be issued pursuant to this Plan, subject to adjustment as provided in
Article IX, shall be 760,500, which is equal to 15.0% of the shares of Common
Stock issued and outstanding immediately subsequent to the Offering.  None of 
such shares shall be the subject of more than one Award at any time, but if an 
Option as to any shares is surrendered before exercise, or expires or 
terminates for any reason without having been exercised in full, or for any 
other reason ceases to be exercisable, the number of shares covered thereby 
shall again become available for grant under the Plan as if no Awards had been 
previously granted with respect to such shares.

       6.02   SOURCE OF SHARES.  The shares of Common Stock issued under the
Plan may be authorized but unissued shares, treasury shares or shares purchased
by the Corporation on the open market or from private sources for use under the
Plan.

                                  ARTICLE VII
                            DETERMINATION OF AWARDS

       7.01   DETERMINATION OF AWARDS.  The Board or the Committee shall, in
its discretion, determine from time to time which Employees will be granted
Awards under the Plan, the number of shares of Common Stock subject to each
Award, whether each Option will be an Incentive Stock Option or a Non-Qualified
Stock Option and the exercise price of an Option.  In making all such
determinations there shall be taken into account the duties, responsibilities
and performance of each respective Employee, his present and potential
contributions to the growth and success of the Corporation, his salary and such
other factors deemed relevant to accomplishing the purposes of the Plan.


                                  ARTICLE VIII
                                    OPTIONS

       Each Option granted hereunder shall be on the following terms and
conditions:

       8.01   STOCK OPTION AGREEMENT.  The proper Officers on behalf of the
Corporation and each Optionee shall execute a Stock Option Agreement which
shall set forth the total number of shares of Common Stock to which it
pertains, the exercise price, whether it is a Non-Qualified Option or an
Incentive Stock Option, and such other terms, conditions, restrictions and
privileges as the Board or the Committee in each instance shall deem
appropriate, provided they are not inconsistent with the terms, conditions and
provisions of this Plan.  Each Optionee shall receive a copy of his executed
Stock Option Agreement.

       8.02 GRANTS TO NON-EMPLOYEE DIRECTORS.  Commencing on the date of the
first annual meeting of the Corporation's stockholders to be held following the
closing of the Offering, and on the date of each annual meeting of the
stockholders thereafter, each person who is a Non-Employee Director of the
Board immediately following each such annual meeting will be automatically
granted a Non-Qualified Option to purchase 4,200 shares of the Corporation's
Common Stock.  If on any date upon which Options are to be granted under this
Plan the number of shares of Common Stock remaining available under the Plan
are less than the number of shares required for all grants to be made on such
date, then Options to purchase a proportionate amount of such available number
of shares of Common Stock shall be granted to each eligible Non-Employee
Director.

       8.03   OPTION EXERCISE PRICE.

              (a)    INCENTIVE STOCK OPTIONS.  The per share price at which the
subject Common Stock may be purchased upon exercise of an Incentive Stock
Option shall be no less than one hundred percent (100%) of the Fair Market
Value of a share of Common Stock at the time such Incentive Stock Option is
granted, except as provided in Section 8.10(b).

              (b)    NON-QUALIFIED OPTIONS.  The per share price at which the
subject Common Stock may be purchased upon exercise of a Non-Qualified Option
shall be established by the Committee at the time of grant, but in no event
shall be less than eighty-five percent (85%) of the Fair Market Value of a
share of Common Stock at the time such Non-Qualified Option is granted.

       8.04  VESTING AND EXERCISE OF OPTIONS.

              (a)    GENERAL RULES.  Incentive Stock Options and Non-Qualified
Options granted to Employees shall become vested and exercisable at the rate of
20% per year on each annual anniversary of the date the Option was granted, and
the right to exercise shall be cumulative, or as otherwise determined by the
Committee.  Notwithstanding the foregoing, no vesting shall occur on or after
an Employee's employment or service, or a Non-Employee Director's service, with
the Corporation and all Subsidiary Companies is terminated for any reason other
than his death or Disability.  In determining the number of shares of Common
Stock with respect to which Options are vested and/or exercisable, fractional
shares will be rounded up to the nearest whole number if the fraction is 0.5 or
higher, and down if it is less.

              (b)    ACCELERATED VESTING.  Unless the Committee shall
specifically state otherwise at the time an Option is granted, all Options
granted under this Plan shall become vested and exercisable in full on the date
an Optionee terminates his employment with the Corporation or a Subsidiary
Company, or service as a Non-Employee Director, because of his death or
Disability.  All Options hereunder shall become immediately vested and
exercisable in full on the date an Optionee terminates his employment with the
Corporation





                                       7
<PAGE>   8
or a Subsidiary Company, or service as a Non-Employee Director, due to
Retirement or as the result of a Change in Control of the Corporation if, as of
such date of such Retirement or Change in Control of the Corporation, such
treatment is either authorized or is not prohibited by applicable laws and
regulations.

       8.05  DURATION OF OPTIONS.

              (a)    GENERAL RULE.  Except as provided in Sections 8.05(b) and
8.10, each Option or portion thereof granted to an Optionee shall be
exercisable at any time on or after it vests and becomes exercisable until the
earlier of (i) ten (10) years after its date of grant or (ii) three (3) months
after the date on which the Optionee ceases to be employed by the Corporation
and all Subsidiary Companies or serve as a Non-Employee Director, unless the
Board or the Committee in its discretion decides at the time of grant or
thereafter to extend such period of exercise upon termination of employment or
service from three (3) months to a period not exceeding five (5) years.

              (b)    EXCEPTIONS.  If an Employee dies while in the employ of
the Corporation or a Subsidiary Company or terminates employment with the
Corporation or a Subsidiary Company as a result of Disability without having
fully exercised his Options, the Optionee or the executors, administrators,
legatees or distributees of his estate shall have the right, during the
twelve-month period following the earlier of his death or termination due to
Disability, to exercise such Options.  If a Non-Employee Director dies while
serving as a Non-Employee Director or terminates his service to the Corporation
or a Subsidiary Company as a result of Disability without having fully
exercised his Options, the Non-Employee Director or the executors,
administrators, legatees or distributees of his estate shall have the right,
during the twelve-month period following the earlier of his death or
termination due to Disability, to exercise such Options.  In no event, however,
shall any Option be exercisable more than ten (10) years from the date it was
granted.  In the event of Retirement, an Employee or Non-Employee Director
shall be entitled to the same time period set forth above in this Section
8.05(b) to exercise an Option if, as of the date of such Retirement, such
treatment is either authorized or is not prohibited by applicable laws and
regulations.

       8.06   NONASSIGNABILITY.  Options shall not be transferable by an
Optionee except by will or the laws of descent or distribution, and during an
Optionee's lifetime shall be exercisable only by such Optionee or the
Optionee's guardian or legal representative.  Notwithstanding the foregoing, or
any other provision of this Plan, an Optionee who holds Non-Qualified Options
may transfer such Options to his or her spouse, lineal ascendants, lineal
descendants, or to a duly established trust for the benefit of one or more of
these individuals.  Options so transferred may thereafter be transferred only
to the Optionee who originally received the grant or to an individual or trust
to whom the Optionee could have initially transferred the Option pursuant to
this Section 8.06.  Options which are transferred pursuant to this Section 8.06
shall be exercisable by the transferee according to the same terms and
conditions as applied to the Optionee.





                                       8
<PAGE>   9
       8.07   MANNER OF EXERCISE.  Options may be exercised in part or in whole
and at one time or from time to time.  The procedures for exercise shall be set
forth in the written Stock Option Agreement provided for in Section 8.01 above.

       8.08   PAYMENT FOR SHARES.  Payment in full of the purchase price for
shares of Common Stock purchased pursuant to the exercise of any Option shall
be made to the Corporation upon exercise of the Option.  All shares sold under
the Plan shall be fully paid and nonassessable.  Payment for shares may be made
by the Optionee in cash or, at the discretion of the Board or the Committee, by
delivering shares of Common Stock (including shares acquired pursuant to the
exercise of an Option) or other property equal in Fair Market Value to the
purchase price of the shares to be acquired pursuant to the Option, by
withholding some of the shares of Common Stock which are being purchased upon
exercise of an Option, or any combination of the foregoing.

       8.09   VOTING AND DIVIDEND RIGHTS.  No Optionee shall have any voting or
dividend rights or other rights of a stockholder in respect of any shares of
Common Stock covered by an Option prior to the time that his name is recorded
on the Corporation's stockholder ledger as the holder of record of such shares
acquired pursuant to an exercise of an Option.

       8.10   ADDITIONAL TERMS APPLICABLE TO INCENTIVE STOCK OPTIONS.  All
Options issued under the Plan as Incentive Stock Options will be subject, in
addition to the terms detailed in Sections 8.01 to 8.09 above, to those
contained in this Section 8.10.

              (a)    Notwithstanding any contrary provisions contained
elsewhere in this Plan and as long as required by Section 422 of the Code, the
aggregate Fair Market Value, determined as of the time an Incentive Stock
Option is granted, of the Common Stock with respect to which Incentive Stock
Options are exercisable for the first time by the Optionee during any calendar
year under this Plan, and stock options that satisfy the requirements of
Section 422 of the Code under any other stock option plan or plans maintained
by the Corporation (or any parent or Subsidiary Company), shall not exceed
$100,000.

              (b)    LIMITATION ON TEN PERCENT STOCKHOLDERS.  The price at
which shares of Common Stock may be purchased upon exercise of an Incentive
Stock Option granted to an individual who, at the time such Incentive Stock
Option is granted, owns, directly or indirectly, more than ten percent (10%) of
the total combined voting power of all classes of stock issued to stockholders
of the Corporation or any Subsidiary Company, shall be no less than one hundred
and ten percent (110%) of the Fair Market Value of a share of the Common Stock
of the Corporation at the time of grant, and such Incentive Stock Option shall
by its terms not be exercisable after the earlier of the date determined under
Section 8.04 or the expiration of five (5) years from the date such Incentive
Stock Option is granted.

              (c)    NOTICE OF DISPOSITION; WITHHOLDING; ESCROW.  An Optionee
shall immediately notify the Corporation in writing of any sale, transfer,
assignment or other disposition (or action constituting a disqualifying
disposition within the meaning of Section





                                       9
<PAGE>   10
421 of the Code) of any shares of Common Stock acquired through exercise of an
Incentive Stock Option, within two (2) years after the grant of such Incentive
Stock Option or within one (1) year after the acquisition of such shares,
setting forth the date and manner of disposition, the number of shares disposed
of and the price at which such shares were disposed of.  The Corporation shall
be entitled to withhold from any compensation or other payments then or
thereafter due to the Optionee such amounts as may be necessary to satisfy any
withholding requirements of federal or state law or regulation and, further, to
collect from the Optionee any additional amounts which may be required for such
purpose.  The Committee may, in its discretion, require shares of Common Stock
acquired by an Optionee upon exercise of an Incentive Stock Option to be held
in an escrow arrangement for the purpose of enabling compliance with the
provisions of this Section 8.10(c).

       8.11          RIGHT OF FIRST REFUSAL.  If at the time an Optionee wishes
to sell Common Stock purchased with an Option granted hereunder, and if at such
time the Common Stock is not publicly traded, then the Corporation shall have
the right to purchase such Common Stock from the Optionee at a price equal to
its Fair Market Value.  If the Corporation does not choose to purchase the
Common Stock from an Optionee, then the other Common Stock shareholders shall
have the right to purchase such Common Stock at a price equal to its Fair
Market Value on a "first-come, first-serve" basis.


                                   ARTICLE IX
                        ADJUSTMENTS FOR CAPITAL CHANGES

       The aggregate number of shares of Common Stock available for issuance
under this Plan, the number of shares to which any outstanding Award relates,
the maximum number of shares that can be covered by Award to each Employee and
each Non-Employee Director and the exercise price per share of Common Stock
under any outstanding Option shall be proportionately adjusted for any increase
or decrease in the total number of outstanding shares of Common Stock issued
subsequent to the effective date of this Plan resulting from a split,
subdivision or consolidation of shares or any other capital adjustment, the
payment of a stock dividend, or other increase or decrease in such shares
effected without receipt or payment of consideration by the Corporation.  If,
upon a merger, consolidation, reorganization, liquidation, recapitalization or
the like of the Corporation, the shares of the Corporation's Common Stock shall
be exchanged for other securities of the Corporation or of another corporation,
each recipient of an Award shall be entitled, subject to the conditions herein
stated, to purchase or acquire such number of shares of Common Stock or amount
of other securities of the Corporation or such other corporation as were
exchangeable for the number of shares of Common Stock of the Corporation which
such optionees would have been entitled to purchase or acquire except for such
action, and appropriate adjustments shall be made to the per share exercise
price of outstanding Options.  Notwithstanding any provision to the contrary,
the exercise price of shares subject to outstanding Awards may be
proportionately adjusted upon the payment of a special large and nonrecurring
dividend that has the effect of a return of capital to the stockholders.

                     AMENDMENT AND TERMINATION OF THE PLAN

       The Board may, by resolution, at any time terminate or amend the Plan
with respect to any shares of Common Stock as to which Awards have not been
granted, subject to any required stockholder approval or any stockholder
approval which the Board may deem to be advisable for any reason, such as for
the purpose of obtaining or retaining any statutory or regulatory benefits
under tax, securities or other laws or satisfying any applicable stock exchange
listing requirements.  The Board may not, without the consent of the holder of
an Award, alter or impair any Award previously granted or awarded under this
Plan as specifically authorized herein.

       Neither the Plan nor the grant of any Awards hereunder nor any action
taken by the Committee or the Board in connection with the Plan shall create
any right on the part of any Employee or Non-Employee Director to continue in
such capacity.

       12.01 TAX WITHHOLDING.  The Corporation may withhold from any cash
payment made under this Plan sufficient amounts to cover any applicable
withholding and employment taxes, and if the amount of such cash payment is
insufficient, the Corporation may require the Optionee to pay to the
Corporation the amount required to be withheld as a condition to delivering the
shares acquired pursuant to an Award.  The Corporation also may withhold or
collect amounts with respect to a disqualifying disposition of shares of Common
Stock acquired pursuant to exercise of an Incentive Stock Option, as provided
in Section 8.10(c).

       12.02 METHODS OF TAX WITHHOLDING.  The Board or the Committee is
authorized to adopt rules, regulations or procedures which provide for the
satisfaction of an Optionee's tax withholding obligation by the retention of
shares of Common Stock to which the Employee would otherwise be entitled
pursuant to an Award and/or by the Optionee's delivery of previously-owned
shares of Common Stock or other property.

         7.01    EARNING PLAN SHARES; FORFEITURES.

                 (a)      GENERAL RULES.  Subject to the terms hereof, Plan
Share Awards shall be earned by a Recipient at the rate of twenty percent (20%)
of the aggregate number of Shares covered by the Award as of each annual
anniversary of the date of grant of the Award.  If the employment of an
Employee or service as a Non-Employee Director is terminated prior to the fifth
(5th) annual anniversary of the date of grant of a Plan Share Award for any
reason (except as specifically provided in subsections (b) and (c) below), the
Recipient shall forfeit the right to any Shares subject to the Award which have
not theretofore been earned.  In the event of a forfeiture of the right to any
Shares subject to an Award, such forfeited Shares shall become available for
allocation pursuant to Section 6.01 hereof as if no Award had been previously
granted with respect to such Shares.  No fractional shares shall be distributed
pursuant to this Plan.

                 (b)      EXCEPTION FOR TERMINATIONS DUE TO DEATH, DISABILITY
OR RETIREMENT.  Notwithstanding the general rule contained in Section 7.01(a),
all Plan Shares subject to a Plan Share Award held by a Recipient whose
employment with or service to the Corporation or any Subsidiary terminates due
to death or Disability shall be deemed earned as of the Recipient's last day of
employment with or service to the Corporation or any Subsidiary prior to his
death or Disability and shall be distributed as soon as practicable thereafter;
provided, however, that Awards shall be distributed in accordance with Section
7.03(a).    In addition, in the event that a Recipient's employment with or
service to the Corporation or any Subsidiary terminates due to Retirement, all
Plan Shares subject to a Plan Share Award held by a Recipient shall be deemed
earned as of the Recipient's last day of employment with or service to the
Corporation or any Subsidiary and shall be distributed as soon as practicable
thereafter; provided, however, that Awards shall be distributed in accordance
with Section 7.03(a) and, as of the date of such Retirement, such treatment is
either authorized or is not prohibited by applicable laws and regulations.

                 (c)      EXCEPTION FOR TERMINATIONS AFTER A CHANGE IN CONTROL
OF THE CORPORATION.  Notwithstanding the general rule contained in Section
7.01(a), all Plan Shares subject to a Plan Share Award held by a Recipient
shall be deemed to be earned in the event of, and as of the date of, a Change
in Control of the Corporation if, as of the date of such Change in Control of
the Corporation, such treatment is either authorized or is not prohibited by
applicable laws and regulations.

                 (d)      REVOCATION FOR MISCONDUCT.  Notwithstanding anything
hereinafter to the contrary, the Board may by resolution immediately revoke,
rescind and terminate any Plan Share Award, or portion thereof, previously
awarded under this Plan, to the extent Plan Shares have not been distributed
hereunder, whether or not yet earned, in the case of an Employee who is
discharged from the employ of the Corporation or any Subsidiary for cause (as
hereinafter defined).  Termination for cause shall mean termination because of
the Employee's personal dishonesty, incompetence, willful misconduct, breach of
fiduciary duty involving personal profit, intentional failure to perform stated
duties, willful violation of any law, rule, or regulation (other than traffic
violations or similar offenses) or final cease-and-desist order.  Plan Share
Awards, to the extent Plan Shares have not been distributed hereunder, granted
to a Non-Employee Director who is removed for cause pursuant to the
Corporation's Articles of Incorporation, as amended, shall terminate as of the
effective date of such removal.

         7.02    DISTRIBUTION OF DIVIDENDS.  Any cash dividends or stock
dividends declared in respect of each unearned Plan Share Award will be held by
the Trust for the benefit of the Recipient on whose behalf such Plan Share
Award is then held by the Trust and such dividends, including any interest
thereon, will be paid out by the Trust proportionately to the shares earned to
the Recipient thereof as soon as practicable after the Plan Share Awards become
earned.  Any cash dividends or stock dividends declared in respect of each
earned Plan Share held by the Trust will be paid by the Trust, as soon as
practicable after the Trust's receipt thereof, to the Recipient on whose behalf
such Plan Share is then held by the Trust.

         7.03    DISTRIBUTION OF PLAN SHARES.

                 (a)      TIMING OF DISTRIBUTIONS:  GENERAL RULE.  Plan Shares
shall be distributed to the Recipient or his Beneficiary, as the case may be,
as soon as practicable after they have been earned, provided, however, that no
Plan Shares shall be distributed to the Recipient or Beneficiary pursuant to a
Plan Share Award within six months from the date on which that Plan Share Award
was granted to such person.

                 (b)      FORM OF DISTRIBUTIONS.  All Plan Shares, together
with any Shares representing stock dividends, shall be distributed in the form
of Common Stock.  One share of Common Stock shall be given for each Plan Share
earned and distributable.  Payments representing cash dividends shall be made
in cash.

<PAGE>   7
                 (c)      WITHHOLDING.  The Trustee may withhold from any cash
payment or Common Stock distribution made under this Plan sufficient amounts to
cover any applicable withholding and employment taxes, and if the amount of a
cash payment is insufficient, the Trustee may require the Recipient or
Beneficiary to pay to the Trustee the amount required to be withheld as a
condition of delivering the Plan Shares.  The Trustee shall pay over to the
Corporation or any Subsidiary which employs or employed such Recipient any such
amount withheld from or paid by the Recipient or Beneficiary.

                 (d)      RESTRICTIONS ON SELLING OF PLAN SHARES.  Plan Share
Awards may not be sold, assigned, pledged or otherwise disposed of prior to the
time that they are earned and distributed pursuant to the terms of this Plan.
Following distribution, the Committee may require the Recipient or his
Beneficiary, as the case may be, to agree not to sell or otherwise dispose of
his distributed Plan Shares except in accordance with all then applicable
federal and state securities laws, and the Committee may cause a legend to be
placed on the stock certificate(s) representing the distributed Plan Shares in
order to restrict the transfer of the distributed Plan Shares for such period
of time or under such circumstances as the Committee, upon the advice of
counsel, may deem appropriate.

         7.04    VOTING OF PLAN SHARES.  All Plan Shares which have not yet
been earned and allocated shall be voted by the Trustee in its sole discretion.

property at any time held or acquired by the Trust.

                 (d)      To cause stocks, bonds or other securities to be

Plan and Trust.

dispute as to the disposition thereof, whether in a segregated account or held
in common with other assets of the Trust.

herein contained, or give bond.

detailed records and accounts of all transactions of the Trust, which shall be

exercise of the Trustee's powers and the discharge of its duties hereunder,

         9.02    AMENDMENT AND TERMINATION OF PLAN.  The Board may, by
resolution, at any time amend or terminate the Plan, subject to any required
stockholder approval or any stockholder approval which the Board may deem to be
advisable for any reason, such as for the purpose of obtaining or retaining any
statutory or regulatory benefits under tax, securities or other laws or
satisfying any applicable stock exchange listing requirements.  The Board may
not, without the consent of the Recipient, alter or impair his Plan Share Award
except as specifically authorized herein.  Upon termination of the Plan, the
Recipient's Plan Share Awards shall be distributed to the Recipient in
accordance with the terms of Article VII hereof.  Notwithstanding anything
contained in this Plan to the contrary, the provisions of Articles VI and VII
of this Plan shall not be amended more than once every six months, other than
to comport with changes in the Code, the Employee Retirement Income Security
Act of 1974, as amended, or the rules and regulations promulgated under such
statutes.

         9.03    NONTRANSFERABLE.  Plan Share Awards and rights to Plan Shares
shall not be transferable by a Recipient, and during the lifetime of the
Recipient, Plan Shares may only be earned by and paid to a Recipient who was
notified in writing of an Award by the Committee pursuant to Section 6.01.  No
Recipient or Beneficiary shall have any right in or claim to any assets of the
Plan or Trust, nor shall the Corporation or any Subsidiary be subject to any
claim for benefits hereunder. Any assets held by the Trust will be subject to
the claims of the Company's general creditors under federal and state law in
the event of the Company's insolvency.  The Company shall be considered
"insolvent" for purposes of this Trust if (i) either the Company is unable to
pay its debts as they become due, or (ii) the Company is subject to a pending
proceeding as a debtor under the United States Bankruptcy Code.

         9.04    EMPLOYMENT OR SERVICE RIGHTS.  Neither the Plan nor any grant
of a Plan Share Award or Plan Shares hereunder nor any action taken by the
Trustee, the Committee or the Board in connection with the Plan shall create
any right on the part of any Employee or Non-Employee Director to continue in
such capacity.
