ITEM 1.  BUSINESS

         This report contains certain statements of a forward-looking nature
relating to future events or the future financial performance of the Company.
Investors are cautioned that such statements are only predictions and that
actual events or results may differ materially.  In  evaluating such
statements, investors should specifically consider the various factors
identified in this Report which could cause actual results to differ materially
from those indicated by such forward-looking statements, including the matters

Results of Operations - Additional Factors Affecting Future Operating Results."

GENERAL BUSINESS DEVELOPMENT

         ACE*COMM(R), incorporated in Maryland in 1983, develops, markets and
services Operations Support System ("OSS") hardware and software solutions for
data and voice networks operated by post, telephone and telegraph companies
("PTTs"), incumbent and competitive local exchange carriers ("CLEC"), national
and international long distance carriers, wireless carriers and large
enterprises operating internal networks.  The Company's products perform
billing data collection, billing, customer care, network surveillance, alarm
processing and network traffic management functions.  The Company's fiscal year
ends on June 30.  Unless otherwise noted, all references to years in this
document are assumed to be fiscal.

PRODUCTS, SERVICES AND DISTRIBUTION

         Data Collection

         DCMS(R) - DCMS, Distributed Call Measurement System, is a hardware and
software based microprocessor controlled product which collects call record
data from telephone switches and electronically transmits them to a central
location, where the data can be processed for such purposes as billing, traffic
analysis and fraud management.  The DCMS eliminates magnetic tape storage units
and manual data collection, reduces processing costs, increases the accuracy of
billing data and in turn, increases revenue.  The most recent version of DCMS
is called Network Element Data Server ("NEDS") which can provide the data on a
real-time basis.  The Company also offers the DCMS*PLUS(R), a version of DCMS
which is based on a new technology platform and is targeted at carriers in
emerging economy countries.  These products can be adapted to support virtually
all wireline and wireless telephone switches.

         N*USAGE - N*USAGE is a software product data collection platform that
enables service providers who operate data networks, including X.25, frame
relay and Asynchronous Transfer Mode ("ATM") to collect billing data and charge
their customers on a usage-sensitive basis.  N*USAGE includes a data collection
front-end and a core processing engine which also acts as a mediator.  The
front-end captures the data and secures it on disk, verifies it then converts
it to a normalized format.  The core processing engine then aggregates the
billing and statistical data, augments any external information and correlates
and reformats the final data before distributing it to the end-user billing and
customer care or network management system.  As more ATM and Frame Relay
switches are incorporated into carrier and enterprise networks, it will become
increasingly important for network managers to be able to bill customers based
on actual usage.

         UPS-32(R) - UPS-32, Universal Polling System-32, is a software
product, designed to control the collection and transmission of call detail
records transmitted by multiple DCMS units and similar equipment of other
vendors.  UPS-32 collects call data from dispersed switch sites, processes and
formats the data on a customer-defined schedule, and distributes the data to
the customer's billing center.  The most recent version of UPS-32, CANS(R),
Central Access Network Server, collects and distributes data in real-time.

         TREX*COMM(R) - TREX*COMM is a software product designed for local
exchange carriers who use network switches to provide customer premises voice
and data communication services for business customers, under a service concept
called CENTREX. TREX*COMM collects CENTREX call usage data from remote switch
sites and transfers it to the customers' data collection equipment.  Records
can then be sorted by customer codes, group codes, or other identifying data
fields. Using standard modem protocols, customers can dial the TREX*COMM system
to retrieve their data. Running on UNIX platforms and used in conjunction with
a data collection product, such as the DCMS,





                                      -3-
<PAGE>   4
TREX*COMM makes network information available to CENTREX subscribers to enable
them to manage and control data.

         Surveillance, Alarm and Traffic Reporting

         UTS-32(R) - UTS-32, Universal Traffic System-32 is a software product
designed to use information gathered by DCMS products or other providers' data
collection products to provide reports on system traffic and usage on a
periodic basis. UTS-32 produces hourly group traffic reports, multi-day study
reports, multi-day load balancing reports, multi-day group traffic analyses,
weekly historical usage reports, yearly trunk forecasting reports, and other
engineering information used to monitor and maximize the efficiency of the
system and enable the carrier to minimize down-time.

         N*VISION(TM) - N*VISION, a successor to the Company's RTMS(R), Real
Time Management System, a system originally developed for use by long distance
carriers, monitors network data in real-time and provides, from a single
database, information for billing, fraud detection, subscriber management and
network management. The heart of N*VISION is a 600 gigabyte data warehouse.
N*VISION operates directly connected to network elements or employs the
Company's  NEDS units to capture call records in real-time from remote
switches. N*VISION processing software presents the data for analysis within
seconds of call completion.

         ANMS(R) - ANMS, AMAT Network Management System, monitors the elements
of a billing network. ANMS is a software product that collects and reports on
alarms sent by DCMSs, UPS-32s and other network components of the billing
system to assure that no billing data is lost. In addition, ANMS serves as a
user interface and collects system logs from the network elements.

         Enterprise Network Management

         NetPlus(R) Voice and Data Network Management System - The NetPlus
family of network management products consists of five systems designed to
automate network operations and management functions.  These systems employ a
client server architecture and common database that permit them to operate
either independently or as an integrated whole.  NetPlus products are
scaleable, providing flexibility to accommodate a broad range of network sizes
and multiple locations.  The Company typically provides NetPlus products as
fully integrated hardware and software configurations.  These products are
intended to manage private voice and data networks for 1,000 to 50,000 users.
These products allow a network to automate tasks such as alarm processing,
connectivity tracking, automatic cable and channel assignment, creation of
subscriber and circuit records, inventory control, traffic surveillance and
management, work order and trouble ticket processing, directory assistance and
subscriber billing.

         Billing and Customer Care

         NetPlus PRO*VISION - NetPlus PRO*VISION is an integrated suite of
software applications that addresses the billing, customer care and OSS
requirements of new and emerging carriers.  NetPlus PRO*VISION is an advanced,
multi-service (voice, data, cable, long distance, etc.) management offering
that performs automated, integrated customer management, operations support and
network maintenance functions.  NetPlus PRO*VISION consists of three major
subsystems, employing a client server architecture and common database that
permit them to operate independently or as an integrated product.   The product
is continually enhanced, through tailoring to specific customer needs.

         The Company's products have been installed in over 1,900 end user
sites in 55 countries.  None of the Company's customers in 1998 contributed 10%
or more of the Company's revenue.

         The Company maintains an ISO 9000 standard Quality Management Program
to monitor the quality of its products and detect errors and has an internal
Quality Management Committee to set quality objectives for the Company and a
Quality Assurance Department to implement and monitor compliance with the
applicable procedures.  The Company has experienced no product returns in the
past 12 years as a result of undetected errors.

SALES AND MARKETING

         The Company sells products through direct sales and through the
Company's strategic alliance partners.  See "Strategic Alliances and Other
Customers."  At present, the Company is increasing its sales efforts through
more aggressive sales and marketing strategies.  The Company is hiring
additional experienced, direct sales representatives and increasing the number
of strategic alliances by adding non-exclusive third party distribution
channels and alliances with new carriers, communications equipment
manufacturers, computer equipment manufacturers, software developers and
telecom consultants, to market the Company's products.

         The sales process for new contracts generally requires a significant
investment of time and money and takes from several months to several years.
This process involves senior executives, sales representatives and support
personnel and typically requires presentations, demonstrations, field trials,
and lengthy negotiations.  The Company spends significant time consulting with
strategic partners and end users to adapt its products to meet end user
requirements.  Through ongoing sales, maintenance, training and systems
analysis, the Company maintains contact with its partners and end users to
determine their evolving requirements for updates and enhancements.  Through
these processes, the Company gains valuable industry expertise, as well as the
ability to identify emerging industry applications and new sales opportunities.

STRATEGIC ALLIANCES AND OTHER CUSTOMERS

         To develop, market and distribute its products effectively, the
Company has established strategic alliances with several large organizations:
Telecom equipment manufacturers, computer equipment manufacturers, telecom
systems integrators and other organizations (the "strategic alliance partners"
or "partners") to which the Company sells products for use by them or their
customers.  The Company sells products through direct sales and through the
Company's strategic alliance partners.  In 1998, sales to strategic alliance
partners and through the direct sales force comprised approximately 40% and 60%
of revenue, respectively.  Each alliance is designed to do one or more of the
following:  develop products designed to meet the needs of the partner or its
customers, establish a joint marketing relationship to include Company products
in systems sold by the partner, and create a reseller channel for the Company's
products.

         A strategic alliance typically involves a formal agreement between the
Company and the strategic alliance partner, pursuant to which the parties agree
to develop and sell products to the partner for use by the partner, or by its
customers who are in such cases the end users of the Company's products.  Each
agreement specifies the terms of the alliance, which may include parameters for
product development and product specifications, product pricing, the terms of
intellectual property ownership, and the responsibilities of each partner for
system integration, proposal drafting, sales and marketing.  Once the products
are developed, the strategic alliance partner will issue specific orders to the
Company from time to time to purchase products, subject to the terms of the
overall agreement.  The products are purchased and paid for by the partner
either for its own use or for resale to its customers directly or as part of a
larger system installation.  Sales to a strategic alliance partner may vary
from period to period, depending on the timing of orders, which in turn may
depend on a number of factors, including the completion of the Company's
product development, the partner's marketing and sales efforts to its
customers, the timing of orders from the partner's customers, and various
internal financial, strategic and other factors specific to a partner or any of
its customers.  Accordingly, sales to a partner in one period are not
necessarily predictive of sales to the partner in future periods.

         The Company plans to continue to develop and expand its strategic
alliances with established, well-recognized industry leaders, as it believes
that these alliances enable the Company to increase sales most cost-effectively
and successfully position it to increase market penetration of its products.

         The following is a list of the Company's more significant strategic
alliances:

- -   ANSTEC, INC. - teamed with the Company and was selected, through a

trained by the Company.  These representatives do not represent the Company
exclusively.  The Company also conducts training classes for its strategic
partners and other customers.

         The Company typically provides new customers with Customer Support for
a period of up to 24 months.  This includes 24 hour, seven days per week
support, replacement parts, software  upgrades, and Year 2000 enhancements,
when and if available.  The Company also offers various levels of continuing
Customer Support after the initial warranty period expires through Technical
Support Agreements.  In addition, the Company provides customers with support
on a time and materials basis.

BACKLOG

         The Company defines backlog as signed contracts or purchase orders for
delivery of hardware and software products and services within the next year.
Backlog at June 30, 1998, 1997 and 1996 was approximately $11.2 million, $7.0
million and $10.4 million, respectively.  Backlog, as defined, does not include
contracts for hardware and software products which require the further issuance
of purchase orders.

         The Company's contracts are large and technically complicated and
require a significant commitment of management and financial resources from the
Company's customers.  The development of a contract is typically a lengthy
process because it must address a customer's specific technical requirements
and often requires internal approvals that require substantial lead-time.
Accordingly, the Company may experience significant variations in revenue from
quarter to quarter, reflecting delays in contract signing or contract order
deliveries.  In addition, contracts that involve software deliveries may
involve tailoring of the product to specific customer requirements, which can
delay final delivery of the order.  No assurance can be given that current
backlog will necessarily lead to revenue in any specific future period.

COMPETITION

         Competition in the market for the Company's products is driven by
rapidly changing technologies, evolving industry standards, frequent new
product introductions and enhancements and rapid changes in customer
requirements.  To maintain and improve its competitive position, the Company
must continue to develop and introduce, on a timely and cost-effective basis,
new products and product features that keep pace with technological
developments and emerging industry standards and address the increasingly
sophisticated needs of its customers.

         The Company expects the continued growth of the traditional carrier
market, new emerging carrier market, and the large enterprise network
management market to encourage new competitors to enter the markets in the
future. The Company believes that the principal competitive factors in these
markets include specialized project management capabilities and technical
expertise, compliance with industry quality standards and protocols, customer
support, product features such as adaptability, scaleability and flexibility,
ability to integrate with other products, functionality





                                     -7-
<PAGE>   8
and ease of use, product reputation, responsiveness to customer needs, and
timeliness of implementation. In the future, the Company will be required to
respond promptly and effectively to the challenges of technological change and
its competitors' innovations.

         In the traditional carrier network products market, the Company's
current and prospective competitors include (i) large carriers which internally
develop full system products for themselves, tailored to their particular
specifications, (ii) companies, such as Axiom, Inc., Comptel and CGI, Inc.
("CGI") that can supply individual billing data collection components and (iii)
vendors that supply product components, including Hewlett-Packard Company
("HP"), IBM Corporation ("IBM"), Moscom Corporation ("Moscom"), Objective
System Integrators, Inc. ("OSI") and CGI.

         In the new and emerging carrier market, the Company's current and
prospective competitors include (i) telecom equipment manufacturers that
provide network products such as Lucent and Ericsson, (ii) companies that
provide software applications for carriers, such as Stonehouse and Metasolv,
(iii) vendors that supply product components such as  HP and IBM, (iv)
companies that provide billing and customer care applications such as Kenan
Systems, Scopus, and Clarify, and (v) companies that develop custom solutions
like AMS, Perot Systems and CSC.

         In the enterprise network management products market, the Company's
current and prospective competitors include (i) companies that provide products
for telephony networks, such as Telco Research Corporation, Complimentary
Solutions, Inc., Stonehouse & Company ("Stonehouse"), Switchview, Inc., Moscom
and OSI and (ii) companies that provide products for data networks, such as
Remedy Corporation, Net Manage, Inc., Computer Associates International, Inc.,
FTP Software, Inc., Castle Rock Computing, HP, IBM and Sun Microsystems, Inc.

         The Company believes that its ability to compete in its markets
depends in part on a number of competitive factors outside its control,
including the ability of others to develop technology that is competitive with
the Company's products, the price at which competitors offer comparable
products and services, the extent of competitors' responsiveness to customer
needs and the ability of the Company's competitors to hire, retain and motivate
key personnel.

         The Company competes with a number of companies that have
substantially greater financial, technical, sales, marketing and other
resources, as well as greater name recognition. As a result, the Company's
competitors may be able to adapt more quickly to new or emerging technologies
and changes in customer requirements, or to devote greater resources to the
promotion and sale of their products than can the Company. There can be no
assurance that the Company's current or potential competitors will not develop
products comparable or superior to those developed by the Company or adapt more
quickly than the Company to new technologies, evolving industry trends or
changing customer requirements.

RESEARCH AND PRODUCT DEVELOPMENT

The Company's research and development efforts are focused on developing new
products to meet the growing needs of customers and on improving existing
products by incorporating new features and technologies.  The Company believes
that the timely development of new products and enhancements is essential to
its maintaining its competitive position in the marketplace.  In its research
and development efforts the Company works closely with customers, end users and
leading technology vendors, in tailoring new features which are subsequently
incorporated into future versions of products available to all customers.  The
Company continually reviews opportunities to license technologies from third
parties when appropriate based on timing and cost considerations.

         During the  years 1998, 1997 and 1996, independent research and
development expenses were  $2.4 million, $1.5 million and $1.0  million,
respectively.

PROPRIETARY RIGHTS AND LICENSES

         The Company does not currently hold any patents and relies on a
combination of copyright, trademark, contract and trade secret laws and
statutory and/or common law to maintain its proprietary rights to its products.
The Company believes that, because of, among other things, the rapid pace of
technological change in the telecommunication and software industries, patent
protection for its products is a less significant factor in the Company's
success than the knowledge, ability and experience of the Company's employees,
the frequency of product enhancements and the timeliness and quality of support
services provided by the Company.

         The Company generally enters into confidentiality agreements with its
employees, consultants, customers and potential customers and limits access to,
and distribution of, its proprietary information.  Use of the Company's
software products is usually restricted to specified locations and is subject
to terms and conditions prohibiting unauthorized reproduction or transfer of
the software products.  The Company also seeks to protect its software,
including the source code, as a trade secret and as copyrighted work.

EMPLOYEES

         At June 30, 1998, the Company employed a total of 175 employees.  None
of the Company's employees are represented by a labor union.  The Company has
experienced no work stoppages and believes that its employee relations are
good.

ITEM 2.  PROPERTIES

         The Company leases space at four office locations: Gaithersburg,
Maryland; Montreal, Canada; Flemington, New Jersey; and Orlando, Florida.  The
Company believes that its facilities are adequate for its current needs and
that suitable additional space will be available as required.  The Gaithersburg
offices are the Company's corporate headquarters and are used for product
assembly, software and engineering development, professional services and
support. The following sets forth information concerning the Company's
Gaithersburg facilities:

         The Company's quarterly operating results have in the past and will in
the future vary significantly as a result of the timing of contract execution,
orders for products, and completion and delivery of significant product orders.
Large orders typically are preceded by long sales cycles and, accordingly, the
timing of such an order has been and will continue to be difficult to predict.
Certain orders are for products that require additional tailoring to customer
requirements and, accordingly, vary in timing of delivery.  The failure to
obtain, or delays in the delivery of, one or more large orders, for any reason,
could have a material adverse effect on the Company's results of operations and
financial condition.  The Company's results also vary based on the type and
quantity of products shipped, the timing of product shipments, the relative
revenue mix in a given period and the resulting margins.  The variations may be
material.

         The timing of large orders depends on a variety of factors affecting
the capital spending decisions of the Company's customers, which in turn, can
affect the Company's quarterly operating results.  These factors include
changes in governmental regulation, changes in the customers' competitive
environment, pricing policies by the Company or its competitors, personnel
changes, demand for the Company's products, the number, timing and significance
of new product and product enhancement announcements by the Company and its
competitors, the ability of the Company to develop, introduce and market new
and enhanced versions of its products on a timely basis, and the mix of direct
and indirect sales and general economic factors.





                                      -13-
<PAGE>   14
         The Company's sales cycle, from initial contact to contract execution,
orders for products and delivery of product, also varies substantially from
customer to customer and from project to project.  The purchase of traditional
carrier network products, new and emerging carrier network products and
enterprise network management products generally involves a significant
commitment of customer capital and management time.  The sales cycle associated
with the purchases of the Company's products is subject to a number of
additional significant risks, including customers' budgetary constraints and
internal acceptance reviews, over which the Company has little or no control.
The product delivery cycle varies from product to product depending on the
extent to which it requires tailoring to a customer's requirement and the
extent to which such requirements are fixed in advance or developed over time.

         The Company's expense levels are based, in part, on its expectations
as to future revenue levels.  If revenue levels are below expectations,
operating results will be materially adversely affected.

         Based upon all of the foregoing, the Company believes that quarterly
revenue and operating results are likely to vary significantly in the future
and that period-to-period comparisons of its results of operations are not
necessarily meaningful and should not be relied upon as indications of future
performance.  Further, it is likely that in some future quarter the Company's
revenue or operating results will be below the expectation of public market
analysts and investors.  In such event, the price of the Common Stock could be
materially adversely affected.

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

OVERVIEW

         The Company sells products to carriers and enterprises, both through
direct channels and through strategic alliance partners, for delivery to end
users in the United States and internationally.  Since June 1994, the Company,
consistent with its strategic emphasis, has derived significant revenue from
sales of its data collection, surveillance, alarm and traffic reporting
products to traditional carriers.  The Company expects such sales to continue
as a significant percentage of its revenue for at least the next several years.
The balance of the Company's revenue is derived from the sale of products and
software licenses to new and emerging carriers and to enterprise customers,
including agencies of the U.S. Government.

         The Company's products typically are sold pursuant to contracts having
an aggregate value of several hundred thousand to several million dollars.
Contracts for the Company's data collection, surveillance, alarm and traffic
reporting products typically require the delivery of products, including
hardware and licensed software, along with installation, training and post
contract support services.  Contracts for billing and customer care and
enterprise network management products typically require the Company to
license, in perpetuity, software applications and provide for hardware and
services that include installation, training and post contract support.
Software, hardware and services sold pursuant to new and emerging carrier and
enterprise network contracts are separately priced.  At the expiration of the
post contract support period, customers are offered the opportunity to purchase
additional support services.

         The Company derives revenues from software license fees, hardware
sales, and product related services.  Revenue from hardware sales is recognized
upon delivery while revenue from product related services is recognized as the
services are rendered.  The Company's software licenses to end users generally
provide for an initial license fee to use the product in perpetuity.  Under
certain contracts, the Company licenses the source code of its software to
resellers for subsequent modification and resale.  Revenue from software
licenses is recognized after the software has been delivered, significant
uncertainties regarding acceptance have expired and significant obligations
have been fulfilled.  Costs relating to insignificant obligations are accrued.
Revenue from contracts with payment terms in excess of one year is recognized
to the extent of payments that are probable and due within one year.  Revenue
related to obligations to provide post contract customer support is unbundled
from the license and recognized ratably over the term of the agreement.
Revenue from maintenance services is recognized ratably over the term of the
related agreement.  None of the Company's customers in 1998 contributed 10% or
more of the Company's revenue.  For contracts involving significant production,
modification or customization of hardware and software, revenue is recognized
using the percentage-of-completion method, based on the relationship of costs
incurred to estimated total costs of the project, which fairly reflects contract
performance milestones.





                                      -14-
<PAGE>   15
         The Company sells its products either as components in the products or
systems developed and marketed by its strategic partners or directly to end
users.  The Company typically experiences higher margins in connection with its
direct sales contracts, offset in part by relatively higher sales and marketing
expenses.

         The Company defines backlog as signed contracts or purchase orders for
delivery of hardware and software products and services within the next year.
Backlog at June 30, 1998, 1997 and 1996 was approximately $11.2 million, $7.0
million and $10.4 million, respectively.  Backlog, as defined, does not include
contracts for hardware and software products which require the further issuance
of purchase orders.

         The Company's revenue is typically concentrated among certain
customers, the largest of which in 1998 consisted of  Logix, Samsung
Electronics, TELMEX, and Winstar.  These customers represented approximately
8%, 8%, 7%, and 6% respectively of total revenue for the year ended June 30,
1998.  Sales to three customers in Asia representing a single end user
comprised approximately 9% of total revenue for the year ended June 30, 1998.
  
         Substantially all of the Company's revenue is derived from
dollar-denominated sales and in 1998 55% of total revenue was generated from
domestic sales.  Although the Company had significant sales in Asia (23% of
total revenue in 1998) and in Canada and Mexico (11% of total revenue in 1998),
the Company does not have significant foreign operations.  The Company's
customers are usually contractually obligated to pay for product in U.S.
dollars.  All products are shipped from the United States pursuant to terms of
orders issued by customers.

         The Company has experienced less favorable cash collection cycles in
both its international sales and its domestic sales in 1998 compared to 1997.
For 1998, days sales outstanding [365/(annual sales/average of year end
accounts receivable)] for sales to U.S. customers was 176 compared to 161 in
1997 (representing a 9% increase). Days sales outstanding for sales to foreign
customers was 182 in 1998 compared to 114 in 1997 (representing a 60%
increase), primarily due to delayed collections associated with the economic
crisis in Korea and the Asia Pacific region.

         As a result of the size of most of its contracts and orders, the
significant length of sales cycles and the complexities which arise from time
to time in completing any given contract or order, the Company typically
experiences fluctuations in quarterly and year-to-year results.  Marketing in
foreign countries, particularly in Asia and other emerging markets, frequently
requires extensive field testing and may result in delays in the timing and
closing of sales by the Company's strategic alliance partners, which in turn
may delay orders of the Company's products.  The Company has experienced
significant delays in timing of revenue related to sales to end users in
overseas markets.

         During 1997, the Company reclassified expenses for services provided
by certain strategic alliance partners in connection with the installation and
integration of the Company's products.  As a result, certain fiscal 1996
amounts have been reclassified from selling, general and administrative expense
to cost of products, software licenses and services, to conform with 1997
financial statement presentation.

         The Company's cost of products, software licenses and services
consists of the cost of product engineering and production, cost of customer
support personnel, license fees paid to third-party software vendors,
amortization of capitalized software development costs, the costs of hardware
purchased by the Company for incorporation into its products and expenses for
services provided by certain alliance partners in connection with the
installation and integration of the Company's products.

         Selling, general and administrative expenses consist of costs to
support the Company's sales and administrative functions.  Included within
these costs are salaries, bonuses, sales commissions, rent, reserves against
doubtful accounts receivable, insurance, depreciation.  Also included are 
costs associated with the company's participation in trade shows and industry
conferences, and related travel and other promotional costs.  

         Research and development expenses consist of personnel costs related
to the design and development of the Company's products.  These costs are
expensed as incurred.  However, computer software development costs incurred
after the technological feasibility of a product is established and until the
product is available for release to customers





                                      -15-

are capitalized.  Capitalized software and purchased technology costs are
amortized on a product by product basis based on the greater of the ratio of
current sales to estimated total future sales or a straight-line basis over the
remaining estimated economic life of the product (no greater than three years)
including the current year.

YEARS ENDED JUNE 30, 1998 AND 1997

Revenues.  Total revenue decreased 33% from $22.5 million compared to $33.7
million for 1997.  The decrease of  $11.2 million was caused by several factors.
First, the economic crisis in Korea and the Asia Pacific region significantly
reduced the amount of orders for the Company's DCMS hardware products compared
to the prior year.  Secondly, the orders expected in 1998 from the Company's
continuing work as one of the subcontractors to the U.S. Air Force, were
indefinitely delayed in mid-1998.  Finally, certain anticipated orders were not
placed until late in the fourth quarter of 1998 and had not been completed by
the end of the year. 

Revenue from traditional carrier network products decreased as a percentage of
total revenue from 65% of total revenue in 1997 to 51% of total revenue in 1998
primarily as a result of the decrease in sales to Korea.  Revenue from
enterprise network products decreased from 25% of total revenue in 1997 to 22%
of total revenue in 1998 primarily as a result of the decreased sales caused
from the delay in orders from the U.S. Airforce.  Revenue from new and emerging
carriers such as Logix, Winstar Telecommunications, and Nextel increased from
10% of revenue in 1997 to 27% of revenue in 1998 primarily as a result of
increased sales of the new NetPlus PRO*VISION product. The Company believes
revenues from sales of its Netplus PRO*VISION products to new and emerging
carriers in North America will continue to increase in the future.

Gross Margins for 1998 were 41% compared to 48% for 1997.  The decrease in the
gross margins was caused by the effect of certain fixed costs on lower volume
of revenue, particularly with regard to sales of DCMS hardware products, the
mix of products and services and the addition of approximately $334,000 of
additional reserves for inventory obsolescence.  The Company expects gross
margins to improve as sales of the NetPlus PRO*VISION product increase, due to
higher gross margins for this product.

Selling General and Administrative expenses for 1998 were $17 million compared
to $11 million in 1997 (which represented 76% and 33% of revenue for 1998 and
1997 respectively) .  A primary cause of the increase was due to the increased
personnel, fringe benefits and facilities costs associated with expansion of
the Company's marketing, sales and administrative functions in anticipation of
receiving significant orders from Korea and the Asia Pacific region before the
economic crisis impacted the Company's business.  Additionally, the Company
increased its reserves for doubtful accounts receivables in 1998 by $2.5
million, considering the increased aging of accounts and the Company's
evaluation of the collectibility of its accounts receivable.

In April 1998, the Company completed a general reduction in staffing which
included administrative personnel.  As a result of these staff reductions and
ordinary turnover, the Company expects selling, general and administrative
expenses to be lower as a percentage of revenue in 1999.

Research and Development expenses for  1998 were $2.4 million (11% of revenue)
compared to $1.5 million (4% of revenue) in 1997.  The increase of $0.9
million was primarily due to the development of the Company's NetPlus
PRO*VISION product line for the new and emerging carrier market.  The Company
plans to spend significant resources on research and development in future
periods in order to enhance its technology, which may have an adverse effect on
the Company's earnings.

Benefit for Income Taxes.  The Company recognized a $898,000 benefit from
income taxes in  1998 compared to a $898,000 provision for income taxes in
1997.  The benefit was recognized as a result of the utilization of the
Company's net operating losses which eliminated its deferred income tax
liability.

YEARS ENDED JUNE 30, 1997 AND 1996





                                      -16-
<PAGE>   17
Revenue.  Total revenue increased 69% from $20.0 million in 1996 to $33.7
million in 1997.  The increase in revenue was attributable to increased sales
volume of the Company's products and software licenses.  Revenue from
traditional carrier network products increased 64%, representing 65% of total
revenues, which growth resulted from increases in sales to foreign strategic
alliance partners that included the Korea Consortium and International
Computers Limited.  Revenue from enterprise network products increased 29%,
representing 24% of total revenues, which growth resulted primarily from
increases in sales of software licenses to ISI Infortext, Tubedale
Communications and International Logistics Systems, Inc.  Revenue from new and
emerging carriers, such as WinStar Telecommunications and SpectraNet
International, represents 10% of 1997 revenues up from 1% in 1996.

Cost of Products, Software Licenses and Services.  Cost of products, software
licenses and services increased 63% to $17.6 million in 1997 from $10.8 million
in 1996 and decreased as a percentage of revenue to 52% from 54%, respectively.
The increase in costs is attributable to increased hardware cost and increased
labor expense associated with the increased annual sales volume and to
increased expenses for services provided by certain alliance partners.  Gross
margins were 48% and 46% for years 1997 and 1996, respectively.  The
improvement in gross margin was primarily the result of an increase in software
license revenue as a percentage of total revenues in 1997.

Selling, General and Administrative.  Selling, general and administrative
expenses increased 67% to $11.0 million in 1997 from $6.8 million in 1996.
These expenses represented 33% and 34% of total revenue in 1997 and 1996,
respectively.  The increased expenses were attributable to costs associated
with increased infrastructure required to support the Company's growth, costs
associated with increased sales and marketing efforts that include the cost of
an expanded sales force and increased rent incurred in conjunction with the
Company's relocation to a larger facility.

Research and Development.  Research and development expense increased 54% to
$1.5 million in 1997 from approximately $1.0 million in 1996.  The increase was
attributable to the addition of software development engineers and technical
consultants required to support the Company's product development activities.
As a percentage of revenue, research and development expense decreased to 4% in
1997 from 5% in 1996.

Provision for Income Taxes.  The Company recorded a tax provision of
approximately $898,000 in 1997, representing an effective tax rate of 26%.
This rate was lower than the expected statutory income tax rate primarily due
to a decrease in the valuation allowance and utilization of foreign tax
credits.  This provision represents an increase of approximately $898,000 over
1996 when no provision was recorded, the result of the provision being offset
by a similar decrease in the valuation allowance.

LIQUIDITY AND CAPITAL RESOURCES

At June 30, 1998 the Company had $2.9 million of cash and cash equivalents,
compared to $7.9 million at June 30, 1997.  During 1998, the Company used $2.3
million in operations, $1.2 million for investment in property and equipment,
and $1.3 million for investment in capitalized software.  The use of cash for
operations was primarily due to the funding of operating losses.  Cash and cash
equivalents available in future periods may be significantly lower than that
available at year end, depending on the results of collections of accounts
receivable and of payments received in connection with contracts.  

Accounts receivables, net of allowances for doubtful accounts, declined to
$10.0 million at June 30, 1998 from $16.1 million at June 30, 1997.  Accounts
receivables include billed accounts receivables, unbilled accounts receivables
and an allowance for doubtful accounts.  Billed accounts receivables declined
to $8.8 million at June 30, 1998 from $13.0 million at June 30, 1997 reflecting
a decline in revenue in 1998 as well as more active management of the
outstanding receivables.  Billed accounts receivable at June 30, 1998 also
reflects the conversion of a $1.6 million account receivable which was
outstanding at June 30, 1997 into a secured note receivable.  At June 30, 1998
the Company had collected approximately $0.5 million leaving a balance on the
note of $1.1 million, which, under the terms of the note is to be paid in full
by September 1999.  Billed accounts receivables, before allowance for doubtful
accounts, at June 30, 1998 included $5.2 million over 90 days.  Unbilled
accounts receivables rose slightly to $3.6 million at June 30, 1998 from $3.1
million at June 30, 1997.  These receivables primarily represent contractual
payment terms which may not be billed for up to twelve months.  During 1998,
the Company increased its allowance for doubtful accounts receivable by





                                      -17-
<PAGE>   18
$2.5 million considering the increased aging of accounts and the Company's
evaluation of the collectibility of its accounts receivables.  The Company
believes these reserves are adequate.

Gross inventories increased from $2.8 million at June 30, 1997 to $3.6 million
at June 30, 1998.  The increase of $0.8 million was primarily due to the
purchase of hardware for a significant order which was received, but not
completed as of June 30, 1998.  In addition the Company increased reserves for
inventory obsolescence from $15,000 at June 30, 1997 to $349,000 at June 30,
1998.  This increase recognizes the obsolescence resulting from the rapidly
changing technology of the industry that the Company operates in and the value
of older inventory, which the Company maintains for support of long-term
maintenance contracts. 

In April 1998, the Company obtained from Crestar Bank of Maryland ("Crestar") a
revolving credit facility ("line of credit") providing for borrowings of up to
$3.5 million which expires December 31, 1998.  Borrowings under the line of
credit are subject to approval by the bank and the bank has the right to refuse
borrowing requests at any time.  Interest on outstanding balances under the line
of credit is payable monthly at the LIBOR rate plus 2 1/2%.  The line of credit
is secured by the general assets of the Company, requires compliance with
certain financial covenants, including positive net income and minimum tangible
net worth and, in the event of default, permits Crestar to accelerate any
outstanding obligations under the line of credit or under any other loans
outstanding from Crestar.  At September 25, 1998, the Company's only borrowings
under the line of credit were letters of credit in the aggregate amount of
$767,000 (see below).  In addition, the Company has term loans outstanding from
Crestar in the aggregate principal amount of $888,000 at June 30, 1998 (see
below).  The Company also maintains its cash at accounts with Crestar.  Crestar
recently notified the Company that it was in default of the line of credit as a
result of the Company's failure to comply with certain financial covenants.  The
Company is in the process of seeking alternative financing.  In the meantime,
Crestar has stated in writing, without waiving any of its rights, that it is not
taking action to enforce its rights and remedies under the line of credit
agreement. However, if the borrowings outstanding under the line of credit (i.e.
the letters of credit and term loans) are repaid in full on or before November
2, 1998, Crestar has agreed to waive its right to collect approximately $35,000
in termination fees.  All amounts due under Crestar borrowings are classified as
current liabilities in the financial statements. 
 
The Company currently is actively seeking alternative financing to replace its
line of credit.  George T. Jimenez, the Chief Executive Officer of the Company
and a significant stockholder, has agreed that in the event that alternative
financing can not be obtained in a timely manner and that, at any time during
the next 12 months the Company's working capital becomes inadequate to support
the business at its then current level, he will make available through a loan
guarantee or a loan, for working capital in the principal amount of up to $3.5
million (less any amounts raised by the Company after September 28, 1998 from
financing activities or through the sale or pledge of assets).  Such loan, if
any would bear interest at prime plus 2%, would be repayable out of the first
alternate funding available to the Company or upon a change of control, if any,
and would be collateralized by the assets of the Company.

In addition, Mr. Jimenez has agreed to provide an unconditional guarantee, 
fully secured by cash or marketable securities, of the Company's reimbursement 
obligation for any amounts paid by Crestar in connection with a $450,000 letter 
of credit issued in connection with the Company's lease of its headquarters 
building (see below). The Company has agreed to reimburse Mr. Jimenez for any 
amounts that he is required to pay under such guarantee.

The Company believes that existing cash balances, cash flows from  operations
and alternate sources of financing (including the financing referred to above
from Mr. Jimenez) will be sufficient to support the Company's working capital
requirements for at least the next twelve months. The Company's ability to
generate sufficient cash flows for working capital is dependent on the
Company's ability to increase sales and to receive from customers in a timely
fashion adequate payments in connection with its contracts. There is no 
assurance that such sales or payment levels will be achieved. If cash flows
from  operations are insufficient to satisfy the Company's working capital 
requirements, the Company will be required to reduce expenses, raise additional 
funds through debt or equity financings or sales of assets and/or consider 
strategic alternatives. There can be no assurance that reductions in expenses 
would be achievable in a timely manner or, if achieved, that they would not 
have a material adverse effect on the Company's ability to generate revenues at 
the levels achieved to date. Further, there is no assurance that adequate 
additional funds will be available, in a timely manner or on terms favorable to 
the Company.

During 1998, the Company paid down debt balances (including its capital lease
obligations) by $488,000.  The long-term debt includes two term loans for
capital equipment and a capital lease obligation with monthly repayment terms,
which are due in varying monthly installment through June 2000 and June 2001.
At June 30, 1998, the balance of term loans and the capital lease obligation
was $1 million compared to $1.5 million at June 30, 1997.  With the exception
of





                                      -18-
<PAGE>   19
a capital lease for an office telephone system, all of the Company's term loans
are with Crestar.  At June 30, 1998, the amount owed to Crestar for the term
loans was $888,000.  These loans bear interest at the bank's prime rate and at
1% over the bank's prime rate, and are secured by accounts receivable,
inventory, specific equipment and by the Company's general assets.   At June
30, 1998, the amount owed on the capital lease was $164,000 and is due in
monthly installments of principal plus interest  (10.03%) through November
2001.  As of September 28, 1998, the Company had made all required payments
under the terms of its loans and capital lease agreement.  

Under the terms of its office lease, the Company maintains a letter of credit
under its line of credit with Crestar, which names the landlord as the sole
beneficiary and which may be drawn on by the landlord in the event of a
monetary default by the Company.  The letter of credit required under the lease
for 1999 is $450,000 decreasing annually through 2003 to $100,000. 

The Company maintains other letters of credit under its line of credit with
Crestar which at September 14, 1998 totaled $327,000.  These letters of credit
represent performance guarantees under the terms of contracts the Company has
entered into with several of its customers and expire through October 31, 1998.

EFFECT OF NEW ACCOUNTING PRONOUNCEMENTS

In October 1998, the AICPA issued SOP 97-2, "Software Revenue Recognition,"
which provides guidance in recognizing revenue on contracts with multiple
elements including software licenses and services and superseded the previous
authoritative literature (SOP 91-1).  SOP 97-2 is effective for the Company for
transactions entered into after June 30, 1998.  In February 1998, the AICPA
proposed deferring, for one year, the implementation date for certain
provisions of SOP 97-2.  This standard is expected to result in more
conservative revenue recognition on software transactions than was allowed
under previous guidance.

In June 1997, the FASB issued SFAS No. 131 entitled "Disclosures about Segments
of an Enterprise and Related Information" which will become effective for the
Company's 1999 financial statements and will apply to quarterly reporting
beginning in the first quarter of 1999.  This Statement may change the way
public companies, having segments, report information about their business in
annual financial statements and may require them to report selected segment
information in their quarterly reports issued to stockholders.  It also
requires entity-wide disclosures about the products and services an entity
provides, the material countries in which it holds assets and reports revenues,
and its major customers.  The Company is currently evaluating reporting and
disclosure requirements under this standard.

In June 1997, the FASB issued SFAS No. 130 entitled "Reporting Comprehensive
Income", which will become effective for the Company's 1999 year and will apply
to quarterly reporting beginning in the first quarter of 1999.  SFAS No. 130
establishes standards for reporting and displaying comprehensive income and it
components.  All items that are required to be recognized under accounting
standards as components of comprehensive income must be reported in a financial
statement that is displayed with the same prominence as other financial
statements.  The Company's principal component of comprehensive income is net
income.  This standard is not expected to materially affect the Company's
reporting and disclosure requirements.

ADDITIONAL FACTORS AFFECTING FUTURE OPERATING RESULTS

         ACE*COMM provides products to a technology driven industry sector.
Therefore, ACE*COMM's success is dependent in part upon factors beyond its
control.  This report contains forward-looking statements relating to the
prospective operating results of the Company.  The following are factors which
could affect ACE*COMM's future operating results.  These factors are intended
to serve as a cautionary statement to statements that may be made, either
verbally or in writing, including those in any other forward-looking statements
made by or on behalf of, the Company:

         To date, a significant portion of the Company's revenue has been
derived from substantial  orders placed by large organizations.  The Company
expects that in the future it will continue to be dependent upon a limited
number of customers in any given period for a significant portion of its
revenue.  The Company's future success may depend upon





                                      -19-
<PAGE>   20
the continued demand by such customers for its products and services.  The
Company's results of operations and financial condition could be materially
adversely affected by the failure of anticipated orders to materialize and by
deferrals or cancellation of orders.

         Sales to traditional carriers have provided and are expected to
continue to provide substantial revenue.  The Company's business is dependent
upon the continued growth of the telecommunications industry, in the United
States and internationally, on the continued convergence of voice and data
networks and on the evolution and widespread adoption of emerging network
technologies.  Any decline in the growth of the industry, the failure of these
markets to converge or the failure of these network technologies to evolve or
achieve widespread market acceptance could have a material adverse effect on
the Company.

         A key element of the Company's business strategy is to develop
strategic alliances with leading companies that provide telecommunications
services or that manufacture and market network equipment in order to expand
the Company's distribution channels and enter new markets.  There can be no
assurance that the Company will be able to continue to increase the number of,
or to expand, these types of relationships, in order to market its products
effectively, particularly internationally.

         The Company's growth has placed significant demands on the Company's
administrative, operational and financial personnel and systems.  Additional
expansion by the Company may further strain the Company's management, financial
and other resources.  There can be no assurance that the Company's systems,
procedures, controls and existing space will be adequate to support continued
growth of the Company's operations.  If the Company is unable to respond to and
manage changing business conditions, the quality of its products and services
and its results of operations could be materially adversely affected.

         The new and emerging carrier market in the United States and overseas
represents a source of growing demand for the Company's products, software
licenses and services.  In that this market segment is relatively new and in
that many of these organizations are in the early stages of their development,
financial resources may be limited and may adversely affect their ability to
pay for the Company's products, software licenses and services.

         The Company derived approximately $10.2 million, or 45% of its total
revenues, from customers outside of the United States in 1998.  The Company
anticipates that a significant amount of future revenues will be derived from
sales to end users in Asia, Europe and other areas of the world.  These
revenues may be adversely affected by the changing economic conditions in
foreign countries, which, in turn, could have a material adverse effect on the
Company's business, financial condition and results of operations.

         The Company's ability to successfully develop new, and enhance
existing, products, to service its customers, and to remain competitive depends
in large part on its ability to attract and retain highly qualified technical,
sales and marketing and management personnel.  Competition for such personnel
is intense, and there can be no assurance that the Company will be able to
continue to attract and retain such personnel.

YEAR 2000

The Company has not completed a thorough assessment of the risks and costs
associated with the Year 2000 issue on internal hardware, software and
non-information technology systems nor has the Company addressed Year 2000
compliance of suppliers providing material incorporated into the Company's
products.

Management believes that risks associated with Year 2000 issues and related
contingency plan arrangements will be resolved such that Year 2000 issues are
adequately mitigated and ongoing operations are not disrupted.

The Company is establishing a program wherein systems will be assessed as to
Year 2000 compliance.  This assessment will include internal infrastructure,
supplier readiness and product evaluation including information technology and
non-information technology systems and applications.  This assessment will
include identifying areas of non-compliance, plans to address known exposures,
implementation of any system changes, validation of Year 2000 compliance and
contingencies to mitigate unknown risk.  The Company has targeted Year 2000
exposures to be





                                      -20-
<PAGE>   21
identified and addressed no later than June 1999.  Attention and priority will
be placed on those systems considered critical to the ongoing operations,
requiring integration with other compliant systems and with longer lead-time
anticipated to remediate.

The cost of addressing the Company's Year 2000 issues has not been quantified,
as assessment of Year 2000 compliance has not been completed.  However,
management is not aware of any Year 2000 compliance exposures which would
preclude ongoing operations during the next twelve months or which would result
in material short-term cash requirements.  There can be no assurance that there
will not be a delay in, or increased costs associated with, the programs
indicated in this section.  Since the assessment is ongoing, the potential
impact of these complications on the Company's financial condition and results
of operations cannot be determined at this time.  If computer systems used by
the Company or its suppliers, the integrity of products provided to the
Company, or the software applications used in systems manufactured and sold by
the Company, fail or experience significant difficulties related to the Year
2000, the Company's operations and financial results could be materially
affected.

                       REPORT OF INDEPENDENT ACCOUNTANTS


To the Board of Directors and Stockholders of
   ACE*COMM Corporation

In our opinion, the financial statements listed in the accompanying index
present fairly, in all material respects, the financial position of ACE*COMM
Corporation at June 30, 1998 and 1997, and the results of its operations and
its cash flows for each of the three years in the period ended June 30, 1998,
in conformity with generally accepted accounting principles. 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 of these statements in accordance with
generally accepted auditing standards which 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, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for the
opinion expressed above.

                              ACE*COMM CORPORATION
                         NOTES TO FINANCIAL STATEMENTS

NOTE 1 - ORGANIZATION

ACE*COMM Corporation ("ACE*COMM" or the "Company") develops, sells and services
Operations Support Systems ("OSS") hardware and software products for data and
voice networks. The Company's customers include telecommunications service
providers and large enterprises operating data and voice networks using
intranets and the Internet. The Company's products perform such functions as
billing data collection, network surveillance, alarm processing and network
management.

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

USE OF ESTIMATES

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions
that affect the amounts reported in the financial statements. Actual results
could differ from those estimates. Significant estimates inherent in the
preparation of the accompanying financial statements include: management's
forecasts of contract costs and progress towards completion which are used to
determine revenue recognition under the percentage-of-completion method,
estimates of allowances for doubtful accounts receivable and inventory
obsolescence, tax valuation allowances, and estimates of the net realizable
value of capitalized software development costs.

REVENUE RECOGNITION

The Company derives revenues from software license fees, hardware sales and
product related services. Revenue from hardware sales is recognized upon
delivery while revenue from product related services is recognized as the
services are rendered. The Company's software licenses to end users generally
provide for an initial license fee to use the product in perpetuity. Under
certain contracts, the Company licenses the source code of its software to
resellers for subsequent modification and resale. Revenue from software
licenses is recognized after the software has been delivered, significant
uncertainties regarding acceptance have expired and significant obligations
have been fulfilled. Costs relating to insignificant obligations are accrued.
Revenue from contracts with payment terms in excess of one year is recognized
to the extent of payments that are probable and due within one year. Revenue
related to obligations to provide post contract customer support without charge
is unbundled from the license and recognized ratably over the term of the
agreement. Revenue from maintenance services is recognized ratably over the
term of the related agreement. For contracts involving significant production,
modification or customization of hardware and software, revenue is recognized
using the percentage-of-completion method, based on the relationship of costs
incurred to the estimated total costs of the project, which fairly reflects
contract performance milestones.

In October 1998, the AICPA issued SOP 97-2, "Software Revenue Recognition,"
which provides guidance in recognizing revenue on contracts with multiple
elements including software licenses and services and superseded the previous
authoritative literature (SOP 91-1). SOP 97-2 is effective for the Company for
transactions entered into after June 30, 1998. In February 1998, the AICPA
proposed deferring, for one year, the implementation date for certain
provisions of SOP 97-2. This standard is expected to result in more
conservative revenue recognition on software transactions than was allowed
under previous guidance.

CASH EQUIVALENTS

The Company considers all investments with an original maturity of three months
or less on their acquisition date to be cash equivalents.

INVENTORIES

                                     F-7
<PAGE>   31

Inventories, which consist principally of purchased materials to be used in the
production of finished goods, are stated at the lower of cost, determined on
the first-in, first-out (FIFO) method, or market.

PROPERTY AND EQUIPMENT

Property and equipment are recorded at cost. Depreciation is calculated using
the straight-line method over the estimated useful lives of the related
equipment and vehicles of seven years. Leasehold improvements are amortized on
a straight-line method over the shorter of the improvements' estimated useful
lives or related remaining lease terms. Long-lived assets held and used by the
Company are reviewed for impairment whenever changes in circumstances indicate
the carrying value of an asset may not be recoverable.

CAPITALIZED SOFTWARE DEVELOPMENT COSTS

The Company owns certain proprietary rights to computer software systems that
the Company has either developed or purchased and licensed to customers.
Purchased computer software and the related copyrights are capitalized at their
costs.

Research and development costs are expensed as incurred. However, computer
software development costs incurred after technological feasibility of a
product is established through the time when the product is available for
release to customers are capitalized. Capitalized software and purchased
technology costs are amortized on a product by product basis based on the
greater of the ratio of current sales to estimated total future sales or a
straight-line basis over the remaining estimated economic life of the product
(no greater than three years), including the current year. The Company
periodically evaluates its capitalized software costs for recoverability
against anticipated future revenues, and writes down or writes off capitalized
software costs if recoverability is in question.

EARNINGS PER SHARE

In February 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 128, "Earnings per Share" ("SFAS 128"). The
Company adopted this statement during the second quarter of 1998, as required.
Accordingly, prior period earnings per share data have been restated to conform
with SFAS 128.

Basic earnings per share excludes dilution and is computed by dividing net
(loss) income by the weighted average of common shares outstanding for the
period.  Diluted EPS reflects the potential dilution that could occur if
securities or other contracts to issue common stock were exercised or converted
into common stock.

INCOME TAXES

Deferred income taxes are recognized for the expected future tax consequences
of temporary differences by applying enacted statutory tax rates to differences
between the financial statement carrying amounts and the tax basis of existing
assets and liabilities.

FAIR VALUE OF FINANCIAL INSTRUMENTS

The carrying amounts of cash and cash equivalents, accounts receivable,
accounts payable, and accrued expenses approximate fair value because of the
short maturity of these items.

The carrying amounts of debt issued pursuant to the Company's bank credit
agreements approximate fair value because the interest rates on these
instruments change with market interest rates.

RECLASSIFICATION

Certain prior year information has been reclassified to conform with current
year presentation.

Unbilled receivables include costs and estimated profit on contracts in
progress which have been recognized as revenue but not yet billed to customers
under the provisions of specific contracts. Substantially all unbilled
receivables are expected to be billed and collected within one year. There were
no write-offs of accounts receivable in 1998, 1997 and 1996.

NOTES RECEIVABLE

In March 1998, the Company converted a $1.6 million account receivable,
outstanding from a prime contractor, to a secured interest-bearing promissory
note, payable over a term of 18 months. Principal and interest payments on the
note are due monthly through September 1999 at an interest rate of prime plus
1%. At June 30, 1998, the outstanding principle balance was $1.1 million, and
all principle and interest payments had been made in accordance with the
payment schedule outlined in the note agreement.

LINE OF CREDIT

In April 1998, the Company obtained from Crestar Bank of Maryland ("Crestar") a
revolving credit facility ("line of credit") providing for borrowings of up to
$3.5 million which expires December 31, 1998. Borrowings under the line of
credit are subject to approval by the bank and the bank has the right to refuse
borrowing requests at any time. Interest on outstanding balances under the line
of credit is payable monthly at the LIBOR rate plus 2 1/2%. The line of credit
is secured by the general assets of the Company, requires compliance with
certain financial covenants, including positive net income and minimum tangible
net worth and, in the event of default, permits Crestar to accelerate any
outstanding obligations under the line of credit or under any other loans
outstanding from Crestar. At June 30, 1998 the balance of borrowings under the
line of credit included a $100,000 draw on the line of credit, which was
subsequently paid in August of 1998, and letters of credit in the aggregate
amount of $743,000 (see Note 14). In addition, the Company has term loans
outstanding from Crestar in the aggregate principal amount of $888,000 at June
30, 1998. The Company also maintains its cash accounts with Crestar. Crestar
recently notified the Company that it was in default of the line of credit as a
result of the Company's failure to comply with certain financial covenants. The
Company is in the process of seeking alternative financing. In the meantime,
Crestar has stated in writing, without waiving any of its rights, that it is not
taking action to enforce its rights and remedies under the line of credit
agreement. However, if the borrowings outstanding under the line of credit (i.e.
the letters of credit and term loans) are repaid in full on or before November
2, 1998, Crestar has agreed to waive its right to collect approximately $35,000
in termination fees. All amounts due under Crestar borrowings are classified as
current liabilities in the financial statements.

The Company currently is actively seeking alternative financing to replace its
line of credit. George T. Jimenez, the Chief Executive Officer of the Company
and a significant stockholder, has agreed that in the event that alternative
financing can not be obtained in a timely manner and that, at any time during
the next 12 months the Company's working capital becomes inadequate to support
the business at its current level, he will make available, through a loan
guarantee or loan, working capital in the principal amount of up to $3.5
million (less any amounts raised by the Company after September 28, 1998 from
financing activities or through the sale or pledge of assets). Such loan, if
any would bear interest at prime plus 2%, would be repayable out of the first
alternate funding available to the Company or upon a change of control, if any,
and would be collateralized by the assets of the Company.

In addition, Mr. Jimenez has agreed to provide an unconditional guarantee, 
fully secured by cash or marketable securities, of the Company's reimbursement 
obligation for any amounts paid by Crestar in connection with a $450,000 letter 
of credit issued in connection with the Company's lease of its headquarters 
building (see Note 14). The Company has agreed to reimburse Mr. Jimenez for any 
amounts that he is required to pay under such guarantee.

The Company believes that existing cash balances, cash flows from operations
and alternate sources of financing (including the financing referred to above
from Mr. Jimenez) will be sufficient to support the Company's working capital
requirements for at least the next twelve months. The Company's ability to
generate sufficient cash flows for working capital is dependent on the
Company's ability to increase sales and to receive from customers in a timely
fashion adequate payments in connection with its contracts. There is no 
assurance that such sales or payment levels will be achieved. If cash flows
from  operations are insufficient to satisfy the Company's working capital 
requirements, the Company will be required to reduce expenses, raise additional 
funds through debt or equity financings or sales of assets and/or consider 
strategic alternatives. There can be no assurance that reductions in expenses 
would be achievable in a timely manner or, if achieved, that they would not 
have a material adverse effect on the Company's ability to generate revenues at 
the levels achieved to date. Further, there is no assurance that adequate 
additional funds will be available, in a timely manner or on terms favorable to 
the Company.


NOTE 8 - RETIREMENT PLAN

The Company has a 401(k) plan, under which to be eligible, employees must have
completed six months of service and be at least 21 years of age and be credited
with 1,000 hours of service.  No contributions were due or made by the Company
in 1998.  During 1997 and 1996, Company contributions were approximately
$103,000 and  $97,000, respectively.

The Company records a valuation allowance for deferred tax assets when it is
management's judgment that it is more likely than not that all or a portion of
a deferred tax asset will not be realized. In 1998, there was a net increase in
the valuation allowance of $1.8 million. This increase primarily relates to
additional income tax net operating losses generated from the current year
operating loss as well as from the deduction created by the exercise of
non-qualified stock options. Any income tax benefit resulting from the
utilization of operating losses will be recognized as a benefit against future
taxable income. Benefit resulting from the exercise of options will be
reflected in additional paid-in-capital (versus through the tax

                                      F-12

provision) when actually realized for tax purposes. Net operating loss deferred
tax assets generated from operating losses and deductions from option exercises
amounted to approximately $2.0 million and $4.8 million, respectively at June
30, 1998 ($381,000 and $3.8 million, respectively at June 30, 1997).

In 1998, the income tax benefit was comprised of a $898,000 benefit resulting
from the reversal of deferred tax liabilities based on the ability of the
Company to utilize current year losses to reduce future payment of such taxes.
The benefit was net of an increase in the valuation allowance of $825,000. In
1997, the provision for income taxes was comprised of $898,000 including a
reduction in the valuation allowance of $277,000. In 1996, the provision for
income taxes was comprised of a Federal and state provision of $458,000 which
was offset by a reduction in the valuation allowance of the same amount.

At June 30, 1998, the Company has available research credit carryforwards of
approximately $252,000, which are available to offset future income tax and
expire in years through 2007. The Company also has net operating loss
carryforwards for tax purposes of approximately $17.5 million that expire in
years 2007 through 2013. Ownership changes as defined by the Internal Revenue
Code, may limit the amount of net operating loss carryforwards that can be
utilized annually to offset future taxable income or liability.

The total income tax (benefit) provision for each year varied from the amount
computed by applying the statutory U.S. Federal income tax rates to net (loss)
income before income taxes as follows (in thousands):

NOTE 10 - STOCKHOLDERS' EQUITY

STOCK OPTIONS

OMNIBUS STOCK PLAN ("OMNIBUS PLAN")

In connection with the Shareholder approved Omnibus Plan, the Company has
reserved 3,200,000 shares of Common Stock to grant nonqualified and incentive
stock options to officers and employees. The exercise price of each option
granted under the Omnibus Plan is determined by the Compensation Committee, and
is limited to a minimum of the fair market value of the Company's Common Stock
on the date of grant. The Omnibus Plan also provides for the issuance of
restricted stock, stock appreciation rights and phantom stock options. The
Company may grant options under the Omnibus Plan until September 18, 2007.

The terms of option grants and issuances of restricted stock, stock appreciation
rights and phantom stock options, including vesting and exerciseability, are
determined by the Compensation Committee. Options and phantom stock options
granted to date vest either immediately or over a period of one to eight years
from the date of grant, subject to accelerated vesting in certain events such as
a change of control, and expire upon the earlier of the employee's termination
or five or ten years from the date of grant. Certain options and phantom stock
options granted in 1997 and 1998 are further subject to accelerated vesting
within one year from the date of grant based on achievement of certain
pre-determined performance goals. Vested options and phantom stock options
become exercisable immediately upon vesting or within three years from the date
of grant. In connection with grants through June 30 1998, the Company had
772,621, 770,510, and 543,744 options and phantom stock options outstanding
subject to performance-based accelerated vesting arrangements at June 30, 1998,
1997 and 1996, respectively. As of June 30, 1998, 1997 and 1996, there were
outstanding phantom stock options totaling 8,082,

                                      F-13
<PAGE>   37

3,082 and 0, respectively, and no restricted stock or stock appreciation
rights had been granted. Compensation cost associated with the 1998 and 1997
phantom stock option grants was immaterial.

During 1998, the Company re-priced 80,000 options with an original exercise
price of $17.75 to the $6.38 fair market value on the date of re-pricing.  No
other terms of the options were modified.  There were no modifications of
option terms in 1997 or 1996.

In July 1998, the Company re-priced 122,984 options and phantom stock options
with original exercise and base unit prices of $12.00 to the $5.00 fair market
value on the date of re-pricing.  No other terms of the options or phantom
stock options were modified.

STOCK OPTION PLAN FOR DIRECTORS ("DIRECTORS' PLAN")

In connection with the Shareholder approved Directors' Plan, the Company has
reserved 200,000 shares of Common Stock to grant nonqualified stock options to
non-employee members of the Company's Board of Directors. The exercise price of
each option granted under the Directors' Plan is limited to a minimum of the
fair market value of the Company's Common Stock on the date of grant. The
Company may grant options under the Directors' Plan until July 1, 2000. 

Options granted to directors through June 30, 1997 vest 4,500 shares each year
from the date of grant. Options granted subsequent to June 30, 1997 vest 3,000
shares each year from the date of grant. Vested options become exercisable
immediately upon vesting. Options granted under the Directors' Plan expire the
earlier of five years from date of grant, six months after death, resignation,
or removal without cause, or immediately upon removal for cause.

Information relating to all the plans is summarized as follows:

NOTE 11 - MANDATORILY REDEEMABLE PREFERRED STOCK

On October 31, 1991, in connection with an investment agreement, the Company
sold 340,211 shares of Class C Preferred Stock at $5.14 per share. The Class C
Preferred stock consisted of two series. Series 1 stock (211,727 shares)
provided voting rights equal to the same number of shares of Common Stock and
Series 2 stock (128,484 shares) provided no voting rights but, if elected by a
majority of the holders of the Class C Preferred Stock, would become voting
shares on a one-to-one basis. Each share of Class C Preferred Stock could be
converted into Common Stock at any time by the holder.

Any shares not converted by designated dates were redeemable by the Company as
follows: one third of the shares on September 15, 1995, one-half of the
remaining shares on September 15, 1996, and all the remaining shares on
September 15, 1997. The redemption price was equal to $5.14 per share plus
accrued dividends. In the case of redemption, the holders were entitled to
receive accrued dividends, at a semi-annual rate of four percent, from November
1, 1992. The Company also had the right to force redemption, if certain
triggering events occur, at a price of $5.14 per share plus accrued dividends
from November 1, 1992, calculated at an annual rate of twelve percent.

In connection with the Company's initial public offering in August 1996, and
pursuant to the terms of the investment agreement, the shares were converted
into 1,530,950 shares of the Company's common stock.

Options to purchase 288,455 shares of Common Stock were outstanding during
1998, but were not included in the computation of diluted EPS because the
effect would have been anti-dilutive.

NOTE 13 - INITIAL PUBLIC OFFERING

On August 13, 1996, in connection with the Company's initial public offering,
2,875,000 shares of Common Stock, 2,645,000 of which were offered by the
Company, were sold at $7.00 per share.  The net proceeds raised by the Company
totaled approximately $16.1 million.

The Mandatorily Redeemable Class C Preferred Stock was automatically converted
into 1,530,950 shares of the Company's Common Stock upon the completion of the
Company's initial public offering.  No dividends were payable with respect to
the converted shares.

On August 28, 1996, the Company redeemed the Class B Preferred Stock for
$308,000 in accordance with its terms that required redemption upon transfer of
substantially all assets or of majority control of the Company.

NOTE 14 - COMMITMENTS AND CONTINGENCIES

As collateral for performance on a long-term contract and to a ceding insurer,
the Company entered into a bond on November 28, 1995 under which the Company is
contingently liable in the amount of $1,175,000.  This bond is in force until
November 28, 1998.

At June 30, 1998 the Company had a $450,000 letter of credit arrangement with
Crestar which guarantees the Company's performance to its landlord (see Note
7).  The letter of credit requirement decreases annually through 2003 to
$100,000.

Additionally, at June 30, 1998, the Company had letter of credit arrangements
with Crestar totaling $293,000 which guarantee the Company's performance under
contracts (see Note 7). Subsequent to June 30, 1998, the Company entered letter
of credit arrangements totaling $34,000 with Crestar, which guarantee the
Company's performance under contracts (see Note 7). These letter of credit
arrangements expire through October 1998.

The Company leases certain office space under non-cancelable operating leases.
Lease terms range from two to seven years and include renewal options for
additional periods. Management expects that in the normal course of business,
leases will be renewed or replaced by other leases. The Company is committed
for the payment of minimum rentals under operating lease agreements through the
year 2004 in the following amounts (in thousands):

                     COLLATERAL ASSIGNMENT, PATENT MORTGAGE
                             AND SECURITY AGREEMENT

      This Collateral Assignment, Patent Mortgage and Security Agreement (the
"Assignment") is made as of the 23rd day of April, 1998, by and between ACE*COMM
CORPORATION, a Maryland corporation ("Assignor"), and CRESTAR BANK ("Assignee").


                                    RECITALS

      Assignee has entered into a Loan and Security Agreement of even date
herewith (as amended, modified or supplemented from time to time, the "Loan
Agreement," the terms defined therein and not otherwise defined herein being
used herein as therein defined) with Assignor. It is a condition precedent to
the making of Loans by Assignee under the Loan Agreement that Assignor shall
have assigned certain property to Assignee in accordance with this Assignment.

      NOW, THEREFORE, FOR VALUABLE CONSIDERATION, THE RECEIPT AND SUFFICIENCY OF
WHICH ARE ACKNOWLEDGED, THE PARTIES HERETO AGREE AS FOLLOWS:

      1.  Assignment, Patent Mortgage and Grant of Security Interest. As
collateral security for the prompt and complete payment and performance of the
Obligations (as defined below), Assignor hereby assigns, transfers, conveys and
grants a security interest and mortgage to Assignee, as security, but not as an
ownership interest, in and to Assignor's entire right, title and interest in, to
and under the following (all of which shall collectively be called the
"Collateral"):

          (a)  All present and future United States registered copyrights and
copyright registrations, including, without limitation, the registered
copyrights listed in Exhibit A-1 to this Agreement (and including all of the
exclusive rights afforded a copyright registrant in the United States under 17
U.S.C. Section 106 and any exclusive rights which may in the future arise by act
of Congress or otherwise) and all present and future applications for copyright
registrations (including applications for copyright registrations of derivative
works and compilations) (collectively, the "Registered Copyrights"), and any and
all royalties, payments, and other amounts payable to Assignor in connection
with the Registered Copyrights, together with all renewals and extensions of the
Registered Copyrights, the right to recover for all past, present, and future
infringements of the Registered Copyrights, and all computer programs, computer
databases, computer program flow diagrams, source codes, object codes and all
tangible property embodying or incorporating the Registered Copyrights, and all
other rights of every kind whatsoever accruing thereunder or pertaining thereto;

          (b)  All present and future copyrights, or contract or license rights
arising from agreements by which Assignor is a licensee, which are not
registered in the United States Copyright Office (the "Unregistered Rights"),
whether now owned or hereafter acquired, including without limitation the
Unregistered Rights listed in Exhibit A-2 to this Agreement, and any and all
royalties, payments, and other amounts payable to Assignor in connection with
the

<PAGE>   2
Unregistered Rights, together with all renewals and extensions of the
Unregistered Rights, the right to recover for all past, present, and future
infringements of the Unregistered Rights, and all computer programs, computer
databases, computer program flow diagrams, source codes, object codes and all
tangible property embodying or incorporating the Unregistered Rights, and all
other rights of every kind whatsoever accruing thereunder or pertaining thereto.
The Registered Copyrights and the Unregistered Rights collectively are referred
to herein as the "Copyrights";

          (c)  All right, title and interest in and to any and all present and 
future license agreements with respect to the Copyrights, including without
limitation the license agreements listed in Exhibit A-3 to this Agreement (the
"Licenses");

          (d)  All present and future accounts, accounts receivable and other
rights to payment arising from, in connection with or relating to the
Copyrights;

          (e)  Any and all trade secrets, and any and all intellectual property
rights in computer software and computer software products now or hereafter
existing, owned by Assignor;

          (f)  Any and all design rights which may be owned by Assignor now or
hereafter existing, created, acquired or held;

          (g)  All patents, patent applications and like protections including,
without limitation, improvements, divisions, continuations, renewals, reissues,
extensions and continuations-in-part of the same, including without limitation
the patents and patent applications set forth on Exhibit B attached hereto
(collectively, the "Patents"), and any and all royalties, payments, and other
amounts payable to Assignor in connection with the Patents, together with all
renewals and extensions of the Patents, the right to recover for all past,
present, and future infringements of the Patents, and all computer programs,
computer databases, computer program flow diagrams, source codes, object codes
and all tangible property embodying or incorporating the Patents, and all other
rights of every kind whatsoever accruing thereunder or pertaining thereto;

          (h)  Any trademark and servicemark rights, whether registered or not,
applications to register, and the entire goodwill of the business of Assignor
connected with and symbolized by such trademarks, including without limitation
those set forth on Exhibit C attached hereto (collectively, the "Trademarks"),
and any and all royalties, payments, and other amounts payable to Assignor in
connection with the Trademarks, together with all renewals and extensions of the
Trademarks, and the right to recover for all past, present, and future
infringements of the Trademarks;

          (i)  Any and all claims for damages by way of past, present and future
infringements of any of the rights included above, with the right, but not the
obligation, to sue for and collect such damages for said use or infringement of
the intellectual property rights identified above;


                                       2
<PAGE>   3

          (j)  All licenses or other rights to use any of the Copyrights, 
Patents or Trademarks, and all license fees and royalties arising from such use
to the extent permitted by such license or rights;

          (k)  All amendments, extensions, renewals and extensions of any of the
Copyrights, Trademarks or Patents; and

          (l)  All proceeds and products of the foregoing, including without
limitation all payments under insurance or any indemnity or warranty payable in
respect of any of the foregoing.


THE INTEREST IN THE COLLATERAL BEING ASSIGNED HEREUNDER SHALL NOT BE CONSTRUED
AS A CURRENT ASSIGNMENT, BUT AS A CONTINGENT ASSIGNMENT TO SECURE ASSIGNOR'S
OBLIGATIONS TO ASSIGNEE.

      This Assignment secures the payment of all obligations of Assignor now or
hereafter existing under the Loan Agreement, including, but not limited to, the
Loans, the Revolving Notes, and all obligations, indebtedness and liabilities of
Assignor under this Assignment and each other Loan Document, and all other
obligations, indebtedness and liabilities of Assignor to Assignee, whether now
existing or hereafter arising, whether or not evidenced by notes or other
instruments, and whether such obligations, indebtedness and liabilities are
direct or indirect, fixed or contingent, liquidated or unliquidated, due or to
become due, joint, several, or joint and several (all such obligations of
Assignor being the "Obligations"). Without limiting the generality of the
foregoing, this Assignment secures the payment of all amounts that constitute
part of the Obligations and would be owed by Assignor to Assignee but for the
fact that they are unenforceable or not allowable due to the existence of a
bankruptcy, reorganization or similar proceeding involving Assignor.

      2.  Authorization and Request. Assignor authorizes and requests that the
Register of Copyrights and the Commissioner of Patents and Trademarks record
this conditional assignment.

      3.  Covenants and Warranties. Assignor represents, warrants, covenants and
agrees as follows:

          (a)  Assignor is now the sole owner of its Collateral, except for
non-exclusive licenses granted by Assignor to its Customers in the ordinary
course of business.

          (b)  Listed on Exhibits A-1 and A-2 are all material Copyrights owned
by Assignor, in which Assignor has an interest (excluding off-the-shelf licensed
software and databases), or which are used in Assignor's business. Listed on
Exhibit A-3 are all material Licenses pursuant to which Assignor has a right to
use the Collateral, in which Assignor has an interest (excluding off-the-shelf
licensed software and databases), or which are used in Assignor's business.
Listed on Exhibit B are all material Patents owned by Assignor, in which
Assignor has an interest, or which are licensed to Assignor for use in
Assignor's business. Listed on Exhibit C are all material Trademarks owned by
Assignor, in which Assignor has an interest, or which are used in Assignor's
business.

                                       3
<PAGE>   4

          (c)  Each employee, agent and/or independent contractor of Assignor 
who has participated in the creation of the property constituting the Collateral
has either executed an assignment of his or her rights of authorship to Assignor
or is an employee of Assignor acting within the scope of his or her employment
and was such an employee at the time of said creation.

          (d)  All of Assignor's present and future Collateral (including,
without limitation, software, computer programs and other works of authorship)
subject or entitled to United States copyright, patent or trademark protection,
the sale, licensing or other disposition of which results in royalties
receivable, license fees receivable, accounts receivable or other sums owing to
Assignor (collectively, "Receivables"), have been and shall be registered with
the United States Copyright Office or the United States Patent and Trademark
Office, as applicable, prior to the date Assignor includes any such Receivables
in the Borrowing Base, and Assignor shall provide to Assignee copies of all such
registrations promptly upon the receipt of the same.

          (e)  Assignor shall undertake all reasonable measures to cause its
employees, agents and independent contractors to assign to Assignor all rights
of authorship to any copyrighted material in which Assignor has or may
subsequently acquire any right or interest.

          (f)  Performance of this Assignment does not conflict with or result
in a breach of any agreement to which Assignor is bound, except to the extent
that certain intellectual property agreements prohibit the disclosure of
information or the assignment of the rights thereunder to a third party without
the licensor's or other party's consent and this Assignment constitutes an
assignment or requires such disclosure.

          (g)  During the term of this Assignment, without the prior written 
consent of Assignee, Assignor will not transfer or otherwise encumber any
interest in the Collateral, except for non-exclusive licenses granted by
Assignor in the ordinary course of business or as set forth in this Assignment.

          (h)  Each part of the Collateral is valid and enforceable, and no part
of the Collateral has been judged invalid or unenforceable, in whole or in part,
and no claim has been made that any part of the Collateral violates the rights
of any third party.

          (i)  Assignor shall promptly advise Assignee of any material change in
the composition of the Collateral, including but not limited to any subsequent
ownership right of Assignor in or to any Trademark, Patent or Copyright not
specified in this Assignment.

          (j)  Assignor shall (1) protect, defend and maintain the validity and
enforceability of the Trademarks, Patents and Copyrights, subject to Assignor's
reasonable business judgment as to the value of the Trademark, Patent or
Copyright, and the cost of such defense, (2) use commercially reasonable efforts
to detect infringements of the Trademarks, Patents and Copyrights and promptly
advise Assignee in writing of material infringements detected, and (3) not allow
any Trademarks, Patents, or Copyrights to be abandoned, forfeited or dedicated
to the public without the written consent of Assignee, which shall not be
unreasonably withheld, unless Assignor determines that reasonable business
practices suggest that abandonment is appropriate.


                                       4
<PAGE>   5

          (k)  Assignor shall promptly register the most recent version of any
of Assignor's Copyrights, Trademarks or Patents, if not so already registered,
that are material to Assignor's business, and shall, from time to time, execute
and file such other instruments, and take such further actions as Assignee may
reasonably request from time to time to perfect or continue the perfection of
Assignee's interest in the Collateral.

          (l)  This Assignment creates, and in the case of after acquired
Collateral, this Assignment will create at the time Assignor first has rights in
such after acquired Collateral, in favor of Assignee a valid and perfected first
priority security interest in the Collateral in the United States securing the
payment and performance of the Obligations upon making the filings referred to
in clause (m) below.

          (m)  To its knowledge, except for, and upon, the filing with the
United States Patent and Trademark office with respect to the Patents and
Trademarks and the Register of Copyrights with respect to the Copyrights
necessary to perfect the security interests and assignment created hereunder and
except as has been already made or obtained, no authorization, approval or other
action by, and no notice to or filing with, any U.S. governmental authority or
U.S. regulatory body is required either (1) for the grant by Assignor of the
security interest granted hereby or for the execution, delivery or performance
of this Assignment by Assignor in the U.S. or (2) for the perfection in the
United States or the exercise by Assignee of its rights and remedies thereunder.

          (n)  All information heretofore, herein or hereafter supplied to
Assignee by or on behalf of Assignor with respect to the Collateral is accurate
and complete in all material respects.

          (o)  Assignor shall not enter into any agreement that would materially
impair or conflict with Assignor's obligations hereunder without Assignee's
prior written consent. Assignor shall not permit the inclusion in any material
contract to which it becomes a party of any provisions that could or might in
any way prevent the creation of a security interest in Assignor's rights and
interest in any property included within the definition of the Collateral
acquired under such contracts.

          (p)  Upon any executive officer of Assignor obtaining actual knowledge
thereof, Assignor will promptly notify Assignee in writing of any event that
materially adversely affects the value of any material Collateral, the ability
of Assignor to dispose of any material Collateral or the rights and remedies of
Assignee in relation thereto, including the levy of any legal process against
any of the Collateral.

      4.  Assignee's Rights. Assignee shall have the right, but not the
obligation, to take, at Assignor's sole expense, any actions that Assignor is
required under this Assignment to take but which Assignor fails to take, after
fifteen (15) days' notice to Assignor. Assignor shall reimburse and indemnify
Assignee for all reasonable costs and reasonable expenses incurred in the
reasonable exercise of its rights under this Section 4.

      5.  Inspection Rights. Assignor hereby grants to Assignee and its
employees, representatives and agents the right to visit, during reasonable
hours upon prior reasonable


                                       5
<PAGE>   6

written notice to Assignor, any of Assignor's plants and facilities that
manufacture, install or store products (or that have done so during the prior
six-month period) that are sold utilizing any of the Collateral, and to inspect
the products and quality control records relating thereto upon reasonable
written notice to Assignor and as often as may be reasonably requested, but not
more than one (1) in every six (6) months.

      6.  Further Assurances; Attorney in Fact.

          (a)  Assignor will make, execute, acknowledge and deliver, and file 
and record in the proper filing and recording places in the United States, all
such instruments, including, appropriate financing and continuation statements
and collateral agreements and filings with the United States Patent and
Trademarks Office and the Register of Copyrights, and take all such action as
may reasonably be deemed necessary or advisable, or as requested by Assignee, to
perfect Assignee's security interest in all Copyrights, Patents and Trademarks
and otherwise to carry out the intent and purposes of this Assignment, or for
assuring and confirming to Assignee the grant or perfection of a security
interest in all Collateral.

          (b)  Upon an Event of Default, Assignor hereby irrevocably appoints
Assignee as Assignor's attorney-in-fact, with full authority in the place and
stead of Assignor and in the name of Assignor, Assignee or otherwise, from time
to time in Assignee's discretion, upon Assignor's failure or inability to do so,
to take any action and to execute any instrument which Assignee may deem
necessary or advisable to accomplish the purposes of this Assignment, including:

               (i)  To modify, in its sole discretion, this Assignment without
first obtaining Assignor's approval of or signature to such modification by
amending Exhibit A-1, Exhibit A-2, Exhibit A-3, Exhibit B and Exhibit C,
thereof, as appropriate, to include reference to any right, title or interest in
any Copyrights, Patents or Trademarks acquired by Assignor after the execution
hereof or to delete any reference to any right, title or interest in any
Copyrights, Patents or Trademarks in which Assignor no longer has or claims any
right, title or interest; and

               (ii) To file, in its sole discretion, one or more financing or
continuation statements and amendments thereto, relative to any of the
Collateral without the signature of Assignor where permitted by law.

      7. Events of Default. The occurrence of any of the following shall
constitute an Event of Default under the Assignment:

          (a)  An Event of Default occurs under the Loan Agreement; or

          (b)  Assignor breaches or fails to perform or observe in any material
respect any representation, warranty or agreement made by Assignor in this
Assignment.



                                       6

      8.  Remedies. Upon the occurrence and continuance of an Event of Default,
Assignee shall have the right to exercise all the remedies of a secured party
under the UCC, including without limitation the right to:

          (a)  require Assignor to assemble any tangible property in which the
Collateral is embodied and in which Assignee has a security interest and to make
it available to Assignee at a place designated by Assignee,

          (b)  exercise any and all rights as beneficial and legal owner of the
Collateral, including, without limitation, any and all consensual rights and
powers with respect to the Collateral, and

          (c)  sell or assign or grant a license to use, or cause to be sold or
assigned or grant a license to use any or all of the Collateral or any part
thereof, in each case, free of all rights and claims of Assignor therein and
thereto, except to the extent such actions would violate restrictions against
assignments contained in any Collateral in which Assignor's rights arise by
contract or license. In that connection, Assignee shall have the right to cause
any or all of the Collateral to be transferred of record into the name of
Assignee or its nominee and the right to impose (i) such limitations and
restrictions on the sale or assignment of the Collateral as Assignee may deem to
be necessary or appropriate to comply with any law, rule or regulation having
applicability to such sale or assignment and (ii) requirements for any necessary
governmental approvals. To the extent not inconsistent with any license or
contract under which Assignor's rights arise, Assignee shall have a
nonexclusive, royalty-free license to use the Copyrights, Patents and Trademarks
to the extent reasonably necessary to permit Assignee to exercise its rights and
remedies upon the occurrence of an Event of Default. Assignor will pay any
expenses (including reasonable attorney's fees) incurred by Assignee in
connection with the exercise of any of Assignee's rights hereunder, including
without limitation any expense incurred in disposing of the Collateral. All of
Assignee's rights and remedies with respect to the Collateral shall be
cumulative.

      9.  Indemnity. Assignor agrees to defend, indemnify and hold harmless
Assignee and its officers, employees, and agents against: (a) all obligations,
demands, claims, and liabilities claimed or asserted by any other party in
connection with the transactions contemplated by this Assignment, and (b) all
losses or expenses in any way suffered, incurred, or paid by Assignee as a
result of or in any way arising out of, following or consequential to
transactions between Assignee and Assignor, whether under this Assignment or
otherwise (including without limitation, reasonable attorneys fees and
reasonable expenses), except for losses arising from or out of Assignee's gross
negligence or willful misconduct.

      10. Release. At such time as Assignor shall completely satisfy all of the
Obligations, Assignee shall execute and deliver to Assignor all assignments and
other instruments as may be reasonably necessary or proper to terminate
Assignee's security interest and any conditional assignment in the Collateral,
subject to any disposition of the Collateral which may have been made by
Assignee pursuant to this Assignment. For the purpose of this Assignment, the
Obligations shall be deemed to continue if Assignor enters into any bankruptcy
or similar proceeding at a time when any amount paid to Assignee could be
ordered to be repaid as a



                                       7
<PAGE>   8

preference or pursuant to a similar theory, and shall continue until it is
finally determined that no such repayment can be ordered.

      11. No Waiver. No course of dealing between Assignor and Assignee, nor any
failure to exercise nor any delay in exercising, on the part of Assignee, any
right, power, or privilege under this Agreement or under the Loan Agreement or
any other agreement, shall operate as a waiver. No single or partial exercise of
any right, power, or privilege under this Assignment or under the Loan Agreement
or any other agreement by Assignee shall preclude any other or further exercise
of such right, power, or privilege or the exercise of any other right, power, or
privilege by Assignee.

      12. Rights Are Cumulative. All of Assignee's rights and remedies with
respect to the Collateral whether established by this Assignment, the Loan
Agreement, or any other documents or agreements, or by law shall be cumulative
and may be exercised concurrently or in any order.

      13. Course of Dealing. No course of dealing, nor any failure to exercise,
nor any delay in exercising any right, power or privilege hereunder shall
operate as a waiver thereof.

      14. Attorneys' Fees. If any action relating to this Assignment is brought
by either party hereto against the other party, the prevailing party shall be
entitled to recover reasonable attorneys fees, costs and disbursements.

      15. Amendments. This Assignment may be amended only by a written
instrument signed by both parties hereto. To the extent that any provision of
this Agreement conflicts with any provision of the Loan Agreement, the provision
giving Assignee greater rights or remedies shall govern, it being understood
that the purpose of this Assignment is to add to, and not detract from, the
rights granted to Assignee under the Loan Agreement. This Assignment, the Loan
Agreement, and the documents relating thereto comprise the entire agreement of
the parties with respect to the matters addressed in this Assignment.

      16. Severability. The provisions of this Assignment are severable. If any
provision of this Assignment is held invalid or unenforceable in whole or in
part in any jurisdiction, then such invalidity or unenforceability shall affect
only such provision, or part thereof, in such jurisdiction, and shall not in any
manner affect such provision or part thereof in any other jurisdiction, or any
other provision of this Assignment in any jurisdiction.

      17. Counterparts. This Assignment may be executed in two or more
counterparts, each of which shall be deemed an original but all of which
together shall constitute the same instrument.

      18. Governing Law and Jurisdiction. This Assignment shall be governed by
the laws of the State of Maryland, without regard for choice of law provisions.
Assignor and Assignee consent to the nonexclusive jurisdiction of any state or
federal court located in Montgomery County, Maryland.

      19. Confidentiality. In handling any confidential information, each of
Assignee and its agents shall exercise the same degree of care that its exercise
with respect to its own 



                                       8
<PAGE>   9

proprietary information of the same types to maintain the confidentiality of any
non-public information thereby received or received pursuant to this Assignment
except that the disclosure of this information may be made (a) to the affiliates
of Assignee, (b) to prospective transferee or purchasers of an interest in the
obligations secured hereby, provided that they have entered into a comparable
confidentiality agreement in favor of Assignor and have delivered a copy to
Assignor, (c) as required by law, regulation, rule or order, subpoena judicial
order or similar order and (d) as may be required in connection with the
examination, audit or similar investigation of Assignee.

      20. WAIVER OF RIGHT TO JURY TRIAL. ASSIGNEE AND ASSIGNOR EACH HEREBY WAIVE
THE RIGHT TO TRIAL BY JURY IN ANY ACTION OR PROCEEDING BASED UPON, ARISING OUT
OF, OR IN ANY WAY RELATING TO: (a) THIS AGREEMENT; OR (b) ANY OTHER PRESENT OR
FUTURE INSTRUMENT OR AGREEMENT BETWEEN ASSIGNEE AND ASSIGNOR; OR (c) ANY
CONDUCT, ACTS OR OMISSIONS OF ASSIGNEE OR ASSIGNOR OR ANY OF THEIR DIRECTORS,
OFFICERS, EMPLOYEES, AGENTS, ATTORNEYS OR ANY OTHER PERSONS AFFILIATED WITH
ASSIGNEE OR ASSIGNOR; IN EACH OF THE FOREGOING CASES, WHETHER SOUNDING IN
CONTRACT OR TORT OR OTHERWISE.

may, in its sole and absolute discretion, make Loans to the Borrower from time
to time until the Termination Date in an aggregate principal amount not to
exceed at any one time outstanding the Maximum Amount. Up to the Maximum Amount,
the Borrower may borrow, repay without penalty and reborrow hereunder from the
date of this Agreement until the Termination Date; provided, however, that no
Loan will be disbursed by the Lender if, after such disbursement the aggregate
principal amount of the Loans would exceed the Borrowing Base. The Borrower
acknowledges and agrees that the Lender has no obligation to make Loans, even if
the Borrower is in compliance with all terms of the Loan Documents, and the
Lender may refuse to make a Loan at any time, and for any reason, without notice
to the Borrower.

          (b)  The proceeds of the Loans shall be used for short-term working 
capital purposes and for no other purposes.

          (c)  The Borrower authorizes the Lender to make Loans from time to
time in amounts sufficient to pay checks drawn on the Borrower's operating
accounts with the Lender, subject to the limitation set forth in Section Section
2.1((a)) above, all as more particularly described in the Cash Management
Agreement. In addition, the Borrower may request that a Revolving Loan be made.
Any request for a Revolving Loan must be received by the Lender no later than
12:00 noon (Washington, D.C. time) on the date on which the Revolving Loan is to
be made. Each request must specify the amount of the Revolving Loan and, at the
option of the Lender, shall be accompanied by a current Borrowing Base
Certificate and a current Aging. The Lender, in its sole discretion, may accept
requests from the Borrower by telephone. If required by the Lender, any request
made by telephone shall include all of the information required by a current
Borrowing Base Certificate and a current Aging. Requests made by telephone shall
be confirmed in writing and delivered to the Lender, and if requested by the
Lender, accompanied by the current Borrowing Base Certificate and the current
Aging, within two Business Days after the date of the request. Loans may be
requested by those individuals designated by the Borrower from time to time in
written instruments delivered to the Lender; provided, however, that the
Borrower shall remain liable with respect to any Loan disbursed by the Lender in
good faith hereunder, even if such Loan is requested by an individual who has
not been so designated. The proceeds of each Loan will be credited to a Deposit
Account maintained with the Lender by the


                                       9
<PAGE>   10


Borrower pursuant to a Cash Management Agreement. The Borrower agrees to confirm
in writing from time to time, when and as requested by the Lender, the purpose
for which the proceeds of each Loan were used.

          (d)  The unpaid principal balance of the Loans shall bear interest at
a rate per annum equal to LIBOR plus 2.50%. The interest rate on the Loans shall
be determined based on LIBOR in effect as of the Closing Date and shall be
adjusted on the first Business Day of each calendar month thereafter to reflect
LIBOR then in effect, with each adjustment to be effective as of the first day
of such calendar month if not a Business Day. Payments of interest on each Loan
shall be made on each Interest Payment Date, beginning on the Interest Payment
Date next succeeding the date of disbursement of such Loan.

          (e)  The obligation of the Borrower to repay the Loans, together with
interest thereon, shall be evidenced by the Revolving Note. The unpaid principal
balance of the Revolving Note shall be payable on demand, or if demand is not
sooner made, on the Termination Date. The Borrower acknowledges that the Lender
may demand payment at any time, even if an Event of Default has not occurred.

          (f)  The Lender from time to time may agree, in its sole discretion,
to extend the Termination Date or increase the amount of Loans to be provided
under this Agreement, or both. During any such periods of extension, the
remaining terms and conditions of this Agreement shall remain in full force and
effect, and the Borrower shall execute and deliver any amendments or
modifications to the Loan Documents that the Lender may require in connection
with any such extension or increase. Nothing in this Section 2.1((f)) shall 
obligate the Lender to grant such extensions or to increase the amount of 
credit provided under this Agreement.

      SECTION 2.2. PAYMENTS AND COMPUTATIONS. All payments due under this
Agreement (including any payment or prepayment of principal, interest, fees and
other charges) or with respect to the Revolving Note or the Loans shall be made
in lawful money of the United States of America, in immediately available funds,
without defense, setoff or counterclaim, to the Lender at its office at
Commercial Loan Services, P.O. Box 26202, Richmond, Virginia 23260-6202, or at
such other place as the Lender may designate, and shall be applied first to
accrued fees, next to accrued late charges, next to accrued interest and then to
principal. If any payment of principal, interest or fees is due on a day other
than a Business Day, then the due date will be extended to the next succeeding
full Business Day and interest and fees will be payable with respect to the
extension. If any payment of principal, interest or fees is not made within ten
days of its due date, the Borrower agrees to pay to the Lender a late charge
equal to 5% of the amount of the payment; provided, however, that as long as the
Borrower makes payments of principal, interest and fees through the Lender's
automatic debit service, no late charge shall be payable if the Lender fails to
debit any such payment when it is due (if sufficient collected funds are on
deposit in the Borrower's account with the Lender), and such failure shall not
constitute an Event of Default hereunder. Upon the occurrence of an Event of
Default and during the continuation of such Event of Default, interest shall
accrue on the Loans at a per annum rate of 2% above the rate 



                                       10
<PAGE>   11

of interest that otherwise would be applicable. Interest and fees shall be
computed on the basis of a year of 360 days and actual days elapsed. The Lender
may, but shall not be obligated to, debit the amount of any payment due from the
Borrower under this Agreement to any deposit or investment account of the
Borrower maintained with the Lender or any Affiliate of the Lender. No setoff,
claim, counterclaim, reduction or diminution of any obligation of any defense of
any kind or nature that the Borrower has or may have against the Lender (other
than the defense of payment) shall be available against the Lender in any suit
or action brought by the Lender to enforce this Agreement or any other Loan
Document. The foregoing shall not be construed as a waiver by the Borrower of
any rights or claims that the Borrower may have against the Lender, but any
recovery upon such rights and claims shall be had from the Lender separately, it
being the intent of this Agreement and the other Loan Documents that the
Borrower shall be obligated to pay, absolutely and unconditionally, all amounts
due hereunder and under the other Loan Documents.

      SECTION 2.3. INCREASED COSTS. If, as a result of any Regulatory Change or
for any other reason, the Lender incurs Increased Costs, the Borrower agrees to
pay such Increased Costs to the Lender within ten Business Days after receipt by
the Borrower of the Lender's invoice therefor. The invoice will be accompanied
by a written statement of the Lender setting forth in reasonable detail the
basis and the calculation of the Increased Costs. The Lender's calculation shall
include reasonable averaging and attribution methods to determine the Increased
Costs attributable to the Loans.

      SECTION 2.4. FEES.

          (a)  In consideration of the expenses incurred by the Lender in
connection with administering the Loans and monitoring the Borrowing Base, the
Borrower agrees to pay to the Lender and administrative fee of $17,000, of which
$9,000 shall be paid on or prior to the Closing Date and the balance of which
shall be payable in monthly installments of $1,000 per month, due on the first
day of each month, beginning on June 2, 1998.

          (b)  If, prior to the Termination Date, the Borrower requests that the
Lender terminate the Credit Facility provided for in this Agreement and release
it security interest in the Collateral, the Borrower shall pay to the Lender,
upon such release, a fee equal to $35,000.

      SECTION 2.5. PRIMARY DEPOSITORY RELATIONSHIP. If the Borrower fails to
maintain its Primary Operating Account with the Lender, interest shall accrue on
the Loans of the Borrower at a per annum rate of 1.0% above the rate of interest
that otherwise would be applicable, effective as of the first day following the
day on which the Borrower moves its Primary Operating Account.

      SECTION 2.6. MANDATORY PREPAYMENT. The Borrower shall prepay the Loans
upon the Lender's demand therefor to the extent that the aggregate amount of
outstanding Loans exceeds the Borrowing Base at any time.

transportation and such other hazards as the Lender shall specify, by insurers

security interest in such policies and the proceeds thereof, and, if any loss
should occur, the proceeds may be applied to the payment of the Obligations or
to the replacement or restoration of the Inventory or Equipment damaged or
destroyed, as the Lender may elect or direct. After the occurrence of an Event
of Default, the Lender shall have the right to file claims under any insurance
policies, to receive, receipt and given acquittance for any payments that may be

contract to the Lender or the receipt by the Lender of any payment relating to
the Receivable pursuant to this Agreement, nor shall the Lender be required or
obligated in any manner to perform or fulfill any of the obligations of the
Borrower under or pursuant to any Receivable or contract, or to make any
payment, or to make any inquiry as to the nature or the sufficiency of any
payment received by it or the sufficiency of any performance by any party under

part of the properties of the Borrower, the appointment shall not have been
vacated; or

remains unpaid, 



                                       25

undischarged, unbonded or undismissed for a period of 30 days, unless and to the
extent that the judgment or attachment is appealed in good faith in a court of
higher jurisdiction and the appeal remains pending; or

          (j)  If the Lender, in good faith, deems itself insecure or determines
that material adverse change has occurred in the financial or business condition
of the Borrower, and the cause for such determination is not cured to the
Lender's satisfaction within 30 days after notice from the Lender to the
Borrower specifying the Lender's basis therefor; or

          (k)  The dissolution, liquidation or termination of existence of the
Borrower; or

          (l)  If the Borrower fails to give the Lender any notice required by
this Agreement within ten days after the occurrence of the event giving rise to
the obligation to give such notice, provided that such failure to give notice
shall not constitute an Event of Default if the applicable Event of Default or
breach is cured within any grace period that otherwise would have been
applicable had the notice been timely given; or

          (m)  If there is a material change in the executive management of the
Borrower that is not acceptable to the Lender; or

          (n)  The occurrence of an event of default under any other Loan
Document and the expiration of all applicable cure periods.

      SECTION 8.2. REMEDIES UPON DEFAULT. Upon the occurrence of an Event of
Default, the following provisions shall be applicable:

          (a)  The Lender, at its option, may terminate its obligation to make
Loans under this Agreement and declare all Obligations, whether incurred prior
to, contemporaneous with or subsequent to the date of this Agreement, and
whether represented in writing or otherwise, immediately due and payable and may
exercise all of its rights and remedies against the Borrower and any Collateral.

          (b)  The Lender may foreclose its lien and security interest in the
Collateral in any way permitted by law and shall have, without limitation, the
remedies of a secured party under the UCC. The Lender may enter the premises of
the Borrower without legal process and without incurring liability to the
Borrower and remove the Collateral to such place or places as the Lender may
deem advisable, or the Lender may require the Borrower to assemble the
Collateral and make the Collateral available to the Lender at a convenient place
and, with or without having the Collateral at the time or place of sale, the
Lender may sell or otherwise dispose of all or any part of the Collateral
whether in its then condition or after further preparation or processing, either
at public or private sale or at any broker's board, in lots or in bulk, for cash
or for credit, at any time or place, in one or more sales and upon such terms
and conditions as the Lender may elect. The Lender shall give not less than ten
Business Days' prior 



                                       26
<PAGE>   27

written notice to the Borrower of the time and place of any public sale of the
Collateral or the time after which the Collateral may be sold in a private sale,
which the Borrower agrees constitutes commercially reasonable notice. At any
such sale the Lender may be the purchaser, subject to the applicable provisions
of the UCC.

          (c)  The proceeds from any sale of the Collateral by the Lender shall
first be applied to any costs and expenses in securing possession of the
Collateral and to any expenses in connection with the sale. The net proceeds
will be applied toward the payment of the Obligations. Application of the net
proceeds as to particular Obligations or as to principal, interest and fees
shall be in the Lender's absolute discretion. Any deficiency will be paid to the
Lender by the Borrower forthwith upon demand, and any surplus will be paid to
the Borrower, as applicable.

          (d)  To the extent that the Obligations are now or hereafter secured
by property other than the Collateral described herein or by the guarantee,
endorsement or property of any other Person, the Lender shall have the right to
proceed against such other guarantee, endorsement or property upon the
occurrence of an Event of Default, and the Lender shall have the right, in its
sole discretion, to determine which rights, security, liens, security interests
or remedies the Lender shall at any time pursue, relinquish, subordinate, modify
or take any other action with respect thereto, without in any way modifying or
affecting any of them or any of the Lender's rights hereunder.

          (e)  The Lender is hereby authorized at any time or from time to time,
without notice to the Borrower (any such notice being expressly waived by the
Borrower), to setoff and apply any deposit (general or special, time or demand,
provisional or final) or investment account at any time held, including any
certificate of deposit, and other indebtedness at any time owed by the Lender or
any of its affiliates, whether or not any such deposit or indebtedness is then
due, to or for the credit or account of the Borrower against any and all of the
Obligations.

          (f)  THE BORROWER, HAVING KNOWLEDGE THAT IT MAY BE ENTITLED TO NOTICE
AND A HEARING PRIOR TO REPOSSESSION OF THE COLLATERAL, WAIVES ANY RIGHT THAT IT
MAY HAVE UNDER EXISTING OR FUTURE LAW TO NOTICE OF FORECLOSURE AND ANY OTHER ACT
DESCRIBED HEREIN, TO ANY HEARING THAT MAY BE HELD RELATING TO FORECLOSURE OR ANY
OTHER SUCH ACTS, AND TO ANY NOTICE THAT MAY BE REQUIRED TO BE GIVEN BY THE
LENDER PRIOR TO SUCH HEARING, OTHER THAN THE NOTICES REQUIRED BY THE LOAN
DOCUMENTS OR THE UCC. THE LENDER AND THE BORROWER EXPRESSLY WAIVE THEIR
RESPECTIVE RIGHTS TO A TRIAL BY JURY WITH RESPECT TO ANY LITIGATION RELATING TO
THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT.



                                       27
<PAGE>   28

          (g)  The Lender itself may perform or comply, or otherwise cause
performance or compliance, with the obligations of the Borrower contained in
this Agreement, including, without limitation, the obligations of the Borrower
to defend and insure the Collateral. The expenses of the Lender incurred in
connection with such performance or compliance, together with interest thereon
at the Prime Rate plus 2%, shall be payable by the Borrower to the Lender on
demand and shall constitute Obligations.

      SECTION 9. MISCELLANEOUS.

      SECTION 9.1. COLLECTION COSTS. The Borrower shall pay all of the
reasonable costs and expenses incurred by the Lender in connection with the
enforcement of this Agreement and the other Loan Documents, including, without
limitation, reasonable attorneys' fees and expenses.

      SECTION 9.2. MODIFICATION AND WAIVER. Except for the other documents
expressly referred to in this Agreement, this Agreement contains the entire
agreement between the parties and supersedes all prior agreements between the
Lender and the Borrower concerning the subject matter hereof. No modification or
waiver of any provision of this Agreement or any other Loan Document and no
consent by the Lender to any departure therefrom by the Borrower shall be
effective unless such modification or waiver shall be in writing and signed by
an officer of the Lender with a title of vice president or any higher office,
and the same shall then be effective only for the period and on the conditions
and for the specific instances and purposes specified in such writing. No notice
to or demand on the Borrower in any case shall entitle the Borrower to any other
or further notice or demand in similar or other circumstances. No failure or
delay by the Lender in exercising any right, power or privilege hereunder shall
operate as a waiver thereof; nor shall any single or partial exercise thereof
preclude any other or further exercise thereof or the exercise of any other
right, power or privilege. The rights and remedies of the Lender contained in
this Agreement and the other Loan Documents are cumulative and not exclusive of
any rights or remedies otherwise provided by law.

      SECTION 9.3. NOTICES. All notices, requests, demands or other
communications provided for in this Agreement (except for requests for Loans
made by telephone as described in Section 2.1 above) shall be in writing and

overnight delivery service) or sent by the United States mail, certified,

20878, Attention: Joseph F. Greeves, Vice President and Chief Financial Officer.

foregoing manner shall be deemed given or made (as the case may be) upon the
earliest of (a) the date it is actually received, (b) the business day after the
day on which it is delivered by hand, (c) the business day after the day on
which it is properly delivered to Federal Express (or a comparable overnight
delivery service), or (d) the third business day after the day on which it is
deposited in the United States mail. The Borrower or the Lender may 



                                       28
<PAGE>   29

change its address by notifying the other party of the new address in any manner
permitted by this Section 9.3. Rejection or other refusal to accept or the 
inability to deliver because of a changed address of which no notice was given 
shall not affect the date of such notice, election or demand sent in accordance
with the foregoing provisions.

      SECTION 9.4. COUNTERPARTS. This Agreement may be executed by the parties
hereto individually or in any combination, in one or more counterparts, each of
which shall be an original and all of which together constitute one and the same
agreement.

      SECTION 9.5. CAPTIONS. The captions of the various sections and paragraphs
of this Agreement have been inserted only for the purposes of convenience; such
captions are not a part of this Agreement and shall not be deemed in any manner
to modify, explain, enlarge or restrict any of the provisions of this Agreement.

      SECTION 9.6. SURVIVAL OF AGREEMENTS. All agreements, representations and
warranties made herein shall survive the delivery of this Agreement and the
making and renewal of the Loans hereunder.

      SECTION 9.7. FEES AND EXPENSES. Whether or not any Loans are made
hereunder, the Borrower shall pay on demand all reasonable out-of-pocket costs
and expenses incurred by the Lender in connection with the preparation,
negotiation, execution, delivery, filing, recording and enforcement of this
Agreement and any of the documents executed or delivered in connection herewith,
including, without limitation, the reasonable fees and expenses of counsel to
the Lender, and local counsel who may be retained by the Lender, with respect to
this Agreement and such documents and any amendments thereof and with respect to
advising the Lender as to its rights and responsibilities thereunder.

      SECTION 9.8. USE OF DEFINED TERMS. All terms defined in this Agreement
shall have the defined meanings when used in certificates, reports or other
documents made or delivered pursuant to this Agreement, unless the context shall
otherwise require.

      SECTION 9.9. SUCCESSORS AND ASSIGNS. This Agreement shall inure to the
benefit of and bind the respective parties hereto and their successors and
assigns; provided, however, that no Borrower may assign its rights hereunder
without the prior written consent of the Lender.

      SECTION 9.10. ACCOUNTING TERMS. All accounting terms used herein that are
not otherwise expressly defined in this Agreement shall have the meanings
respectively given to them in accordance with GAAP in effect on the date of this
Agreement. Except as otherwise provided herein, all financial computations made
pursuant to this Agreement shall be made in accordance with GAAP and all balance
sheets and other financial statements shall be prepared in accordance with GAAP.
Except as otherwise provided herein, whenever reference is made in any provision
of this Agreement to a balance sheet or other financial statement or financial




                                       29
<PAGE>   30

computation with respect to the Borrower, such terms shall mean a consolidated
balance sheet or other financial statement or financial computation, as the case
may be, with respect to the Borrower and its Subsidiaries.

      SECTION 9.11. CONFIDENTIALITY. Except as otherwise provided by applicable
law, the Lender shall utilize all non-public information obtained pursuant to
the requirements of this Agreement which has been identified as confidential or
proprietary by the Borrower in accordance with its customary procedure for
handling confidential information of this nature and in accordance with safe and
sound banking practices but in any event may make disclosure: (a) to any of its
affiliates (provided they shall agree to keep such information confidential in
accordance with the terms of this Section); (b) as reasonably required by any
bona fide assignee, participant or other transferee in connection with the
contemplated transfer of any Loan or participations therein (provided they shall
agree to keep such information confidential in accordance with the terms of this
Section); (c) as required by any governmental authority or representative
thereof or pursuant to legal process; (d) to the Lender's independent auditors,
counsel and other professional advisors (provided they shall be notified of the
confidential nature of the information); and (e) after the happening and during
the continuance of an Event of Default, to any other Person, in connection with
the exercise by the Lender of rights hereunder or under any of the other Loan
Documents.

      SECTION 9.12. INTERPRETATION. This Agreement and the rights and
obligations of the parties hereunder shall be construed and interpreted in
accordance with the laws of the State of Maryland, without reference to conflict
of laws principles.

      SECTION 9.13. NATURE OF CREDIT FACILITY. The Borrower acknowledges and
agrees that the enumerated Events of Default are merely examples of the types of
occurrences that may cause the Lender to make a demand for payment or to refuse
to make a Loan, and neither they nor any other provision of this Agreement shall
limit the Lender's rights to demand payment or refuse to make a Loan whenever it
chooses.

$3,500,000                                                        April 23, 1998

      FOR VALUE RECEIVED, ACE*COMM CORPORATION, a Maryland corporation (the
Borrower), hereby promises to pay to the order of CRESTAR BANK, a Virginia
banking corporation (the Lender), at Commercial Loan Services, P.O. Box 26202,
Richmond, Virginia 23260-6202, or such other location as the holder hereof may
in writing designate, the principal sum of THREE MILLION FIVE HUNDRED THOUSAND
AND NO/100 DOLLARS ($3,500,000) (or such lesser amount as shall equal the
aggregate unpaid principal amount of the Loans made by the Lender to the
Borrower under the Loan Agreement described below), in lawful money of the
United States of America in immediately available funds, on demand, without
defense, offset or counterclaim, and to pay interest on the unpaid principal
amount of the Loans, at such office, in like money and funds, for the period
commencing on the date of each Loan until such Loan shall be paid in full, at
the rate per annum and on the dates provided in the Loan Agreement. The Borrower
may borrow, prepay without penalty, and reborrow hereunder in accordance with
the provisions of the Loan Agreement.

      The Lender is hereby authorized by the Borrower to maintain records of the
amount of each Loan made by the Lender, the date such Loan is made, and the
amount of each payment or prepayment of principal of such Loan received by the
Lender. The Borrower agrees that the amounts so evidenced in such records,
absent manifest error, shall constitute conclusive evidence of the amount owed
hereunder.

      This Revolving Note is the Revolving Note referred to in the Loan and
Security Agreement (as amended, modified or supplemented from time to time, the
Loan Agreement), of even date herewith, between the Borrower and the Lender, and
evidences Loans made by the Lender thereunder. Capitalized terms used in this
Revolving Note have the respective meanings assigned to them in the Loan
Agreement.

      Upon the occurrence and continuation of an Event of Default, the principal
hereof and accrued interest hereon may be declared to be, or may become,
forthwith due and payable in the manner, upon the conditions and with the effect
provided in the Loan Agreement.

      The Borrower, every guarantor and endorser hereof hereby waive
presentment, demand, notice of dishonor, protest and all other demands and
notices in connection with the delivery, acceptance, performance and enforcement
of this Revolving Note.

      Upon the occurrence of an Event of Default, the Borrower hereby authorizes
any attorney designated by the Lender or any Clerk of any court of record to
appear for the Borrower in any court of record and to confess judgment without
prior hearing against the Borrower in favor of 

<PAGE>   2

the Lender for and in the amount of the unpaid principal balance hereof, all
interest accrued and unpaid thereon, all other amounts payable by the Borrower
to the Lender under the terms of this Note or any of the other Loan Documents,
costs of suit, and attorneys' fees of $7,500 (if judgment be entered without
contest). If confession of judgment is contested, attorneys' fees under this
paragraph shall be ten percent (10%) of the unpaid principal balance hereof and
interest then due hereunder. The Borrower hereby releases, to the extent
permitted by applicable law, all errors and all rights of exemption, appeal,
stay of execution, inquisition, and other rights to which the Borrower may
otherwise be entitled under the laws of the United States of America or of any
state or possession of the United States of America now in force or which may
hereafter be enacted. The authority and power to appear for and enter judgment
against the Borrower shall not be exhausted by one or more exercises thereof or
by any imperfect exercise thereof and shall not be extinguished by any judgment
entered pursuant thereto. Such authority may be exercised on one or more
occasions or from time to time in the same or different jurisdictions as often
as the Lender shall deem necessary or desirable, for all of which this Note
shall be a sufficient warrant. Notwithstanding any provision of this paragraph,
the Borrower retains its rights pursuant to Maryland Rules of Civil Procedure
Rule 2-611.

      This Revolving Note shall be governed by and construed in accordance with
the laws of the State of Maryland, without reference to conflict of laws
principles.

      IN WITNESS WHEREOF, the Borrower has caused this Revolving Note to be
executed by its duly authorized representative as of the day and year first
above written.

EXHIBIT 99.1

                    SEPARATION AGREEMENT AND GENERAL RELEASE

         This Separation Agreement and General Release (hereinafter
"Agreement") is hereby entered into January 2, 1998, effective as of January 1,
1998, between ACE*COMM Corporation (hereinafter "the Company") and James M.
Moore (hereinafter "Mr. Moore"), who are collectively referred to herein as the
"Parties."

         WHEREAS, Mr. Moore has served as Vice President - Marketing of the 
Company; and

         WHEREAS, for personal reasons, Mr. Moore is resigning as officer of the
Company; and

         WHEREAS, the Parties desire to enter into this Agreement on the date
hereof to set forth their agreement with respect to Mr. Moore's resignation and
certain other matters in connection therewith; and

         WHEREAS, the Parties desire that this Agreement supersede any
agreement, arrangement or understanding with respect to Mr.  Moore's terms of
employment by the Company to the extent set forth herein.

         NOW, THEREFORE, In consideration of the mutual promises contained
herein, and other good and valuable consideration as hereinafter recited, the
receipt and adequacy of which is hereby acknowledged, the Parties, intending to
be legally bound, agree as follows:

1.  Resignation; Termination of employment.  The Company and Mr. Moore have
    agreed that, effective immediately, he hereby tenders his resignation as an
    officer of the Company, and that he will remain as an active status
    employee of the Company until May 30, 1998 (or such earlier time as he
    breaches a term of this Agreement), whereupon his employment with the
    Company shall terminate.

2.  Special Projects.  During the balance of the term of his employment, Mr.
    Moore shall perform such special projects as may be assigned to him from
    time to time by the Chief Executive Officer of the Company.

3.  Non-competition, non-solicitation and confidentiality.  Mr. Moore agrees
    that, for a period of three (3) years from the date of this Agreement, he
    will not, either within or without the United States, directly or
    indirectly, as a stockholder, partner, investor, director, officer,
    employee, consultant, contractor, agent or in any other capacity, engage
    any business that is in competition with the business presently conducted
    by the Company (the "Business"), provided that the foregoing shall not
    prohibit Mr. Moore from owning beneficially less than 5% of the outstanding
    stock of any class of



                                                                     Page 1 of 8
<PAGE>   2
    stock of a corporation the securities of which are regularly traded or
    quoted on a national securities exchange or on an inter-dealer quotation
    system.  Specifically, but without limiting the generality of the
    foregoing, Mr. Moore shall not directly or indirectly:

         (a)  Contract with, represent, solicit business or engage in the
         Business to develop, market or sell billing data collection or network
         management systems;

         (b)  Solicit business or in any other way interfere with or disrupt
         the Company's business relationships with any persons in the Business;

         (c)  Solicit, hire, contract with or enter into any business dealings
         with, entice or aid, or cooperate with others in soliciting or
         enticing any current or future employees of the Company to leave the
         Company and join any other company in the Business;

         (d)  Divulge any confidential information regarding the business to
         anyone not connected with the Company;

         (e)  "indirect" competition shall include any competition undertaken
         through an entity owned in whole or in part by Mr.  Moore or any agent
         or affiliate thereof.

    Mr. Moore shall at all times hold in confidence any and all
    confidential information that may have come into his possession or within
    his knowledge concerning research activities, products and services offered
    or being considered, mergers and other major corporate transactions being
    considered, inventions, innovations, designs, ideas, plans, trade secrets,
    proprietary information, advertising, distribution and sales methods and
    systems, customer lists, and relationships between, or information about,
    the Company and its employees, consultants, dealers, distributors,
    customers and others who have had or will have business dealings with the
    Company ("Confidential Information").  Mr. Moore acknowledges that such
    Confidential Information is a valuable and unique asset and shall not
    disclose any such Confidential Information directly or indirectly unless
    such information has become generally available to the public other than as
    a result of a breach of contract or fiduciary duty or unless required to do
    so by court order.

    Mr. Moore acknowledges that there is no adequate remedy at law for a
    breach of this Paragraph 3 and that, in the event of such breach, or
    attempted breach, the Company shall be entitled to injunctive or other
    equitable relief to prevent any such breach, attempted breach or continuing
    breach, without prejudice to any other remedies for damages or otherwise.
    Mr. Moore agrees that the covenants in this Paragraph are separate and
    reasonable in  their scope and duration and that he shall not raise any
    issue of reasonableness as a defense in any proceeding to enforce this
    covenant.  Notwithstanding the foregoing, should any court determine that
    this Paragraph shall be unenforceable with respect to scope, duration or
    geographic area, the Parties agree


                                                                    Page 2 of 8
<PAGE>   3
    that such court shall be empowered to substitute, to the extent
    enforceable, provisions similar hereto or other provisions so as to provide
    to the Company, to the fullest extent permitted by applicable law, the
    benefits intended by this Agreement.  The validity, legality or
    enforceability of any remaining provisions of this Agreement shall not be
    affected by any such modification.

4.  Salary and loan forgiveness.  As consideration for his continued employment
    and the agreements in Paragraph 3, the Company agrees (i) to continue to
    pay Mr. Moore through the date of termination of his employment his salary
    at the rate in effect on the date of this Agreement, on a bi-weekly basis,
    and (ii) to forgive on each of the next three anniversaries of the date of
    this Agreement repayment of one third of the outstanding principal and
    interest of that certain Note dated June 5, 1997 in the principal amount of
    $133,000 (the "Note"), subject to Mr. Moore's continuing compliance with
    the terms and conditions of this Agreement.  In the event that Mr. Moore
    breaches one or more of the provisions of this Agreement, without limiting
    the Company's other remedies, including any right to damages, the
    unforgiven amounts under the Note shall remain due and payable in full in
    accordance with the terms of the Note.

    Mr. Moore will have no other benefits of employment, including
    compensation, access to premises, use of equipment and contact with
    suppliers, employees and customers, except to the extent otherwise
    expressly set forth herein.  Mr. Moore agrees that, but for this Agreement,
    he is not otherwise entitled to the above-described consideration from the
    Company.

5.  Stock options.  Attached as Exhibit A is an Amended and Restated Stock
    Option Agreement dated as of August 14, 1996 exercisable for 63,000 shares
    and as Exhibit B, an Amended and Restated Stock Option Agreement dated as
    of April 30, 1997 exercisable for 4,500 shares (together, these option
    agreements are referred to as the "Option Agreements").  The Option
    Agreements shall become exercisable in full on May 14, 1998.

    For purposes of Section 4.1 of the Option Agreements, Mr. Moore will
    be deemed to be employed by the Company until the earlier of May 30, 1998,
    or such earlier time, if any, as he breaches a term of this Agreement.  The
    Option Agreements are subject to the terms of the Company's Amended and
    Restated Omnibus Stock Plan, as amended from time to time, (the "Plan")
    and, to the extent the terms of the Option Agreements are inconsistent with
    the terms of the Plan, the terms of the Plan shall prevail as, interpreted
    in good faith by the Board of Directors of the Company.  Section 5.3 of the
    Option Agreements is hereby deleted.  The Option Agreements shall be
    nontransferable otherwise than by will or the laws of descent and
    distribution.  Until the Option Agreements are terminated (which shall
    occur no later than May 30, 1998), in the event of a change of control of
    the Company, the options granted thereunder shall be treated in
    substantially the same manner as those of other officers and directors of
    the Company.


                                                                    Page 3 of 8
<PAGE>   4
    The Parties agree that Mr. Moore is not entitled to any other stock options
    and that any agreements with respect to stock options other than the Option
    Agreements hereby are terminated and are superseded by the terms of this
    Agreement.  The Option Agreements shall otherwise continue in full force
    and effect in accordance with their terms except to the extent otherwise
    modified pursuant to the terms of this Agreement.

6.  Taxes.  Mr. Moore agrees that he is solely responsible for any and all
    taxes on payments or other compensation described herein, subject to any
    required withholding by the Company, as to which Mr. Moore hereby consents.
    Mr. Moore further agrees to indemnify and hold harmless the Company from
    any and all costs, expenses, including but not limited to, reasonable
    attorneys' fees, judgments, liabilities, tax liabilities or penalties,
    interest, claims, payment of moneys, demands, losses, damages, and
    penalties, except for the Company's share of FICA payments, which the
    Company may hereafter sustain, incur or be required to pay as a consequence
    of, for or by reason of, resulting from, arising out of, or relating in any
    way to this payment to Mr. Moore.  While the payments made herewith are
    intended by the parties to be other than back pay, Mr. Moore understands
    and acknowledges that the Company makes no representations to him regarding
    the income tax treatment or consequences of any consideration paid in
    connection herewith.

7.  Health, life and disability insurance.  The Company further agrees to
    provide Mr. Moore and his dependents continuing coverage under the
    Company's health, life and disability policies at his current level of
    benefits until May 30, 1998, to the extent permitted under these policies
    and, thereafter, only to the extent expressly required under the
    Consolidated Omnibus Budget Reconciliation Act of 1985 (COBRA), as amended.
    Mr. Moore recognizes that for purposes of the continuation coverage
    requirements of group health plans under and the group health provisions of
    the Maryland Annotated Code, a "qualifying event" and "applicable change in
    status" occurs at the earlier of May 30, 1998 or the date that Mr. Moore is
    earlier terminated as an employee of the Company.

8.  Surrender of Company property and no authority.  Mr. Moore agrees that upon
    the termination of his employment with the Company, he will surrender to
    the Company every item and every document that came into Mr. Moore's
    possession in the course of his employment at the Company or that is the
    Company's property (including but not limited to keys, records, computers,
    peripherals, computer files and disks, notes, memoranda, models, inventory
    and equipment) or contains Company information, in whatever form.  All of
    these materials are the sole and absolute property of the Company.  In
    addition, Mr. Moore shall not represent to any third party that he is an
    employee or agent of the Company and he acknowledges that as of the date
    hereof, he has no authority to, and will not attempt to, legally bind or
    otherwise obligate the Company.


                                                                    Page 4 of 8
<PAGE>   5

9.  References.  All reference requests from Mr. Moore's prospective employers
    shall be made in writing addressed to the attention of George Jimenez, and
    shall include a written authorization signed by Mr. Moore for the release
    of the information.  The Company will provide to prospective employers the
    following information:  Mr.  Moore's dates of employment; Mr. Moore's job
    title; and Mr. Moore's last annual compensation.

10. Release of the Company.  Mr. Moore agrees that, in consideration of the
    payments and consideration described above, on behalf of himself and anyone
    claiming through him, he will, and hereby does, forever and irrevocably,
    release and discharge the Company, its officers, directors, stockholders,
    employees, agents, affiliates, predecessors, purchasers, assigns,
    representatives, successors, successors in interest, and customers from any
    and all grievances, claims, demands, debts, defenses, actions or causes of
    action, obligations, contracts, promises, damages, judgments, expenses, and
    liabilities, known or unknown, whatsoever, which he now has, has had, or
    may have, whether the same be at law, in equity, or mixed, in any way
    arising from or relating to any act, occurrence, or transaction before the
    date of this Agreement, including without limitation his anticipated
    separation of employment.  This is a General Release.  Mr. Moore expressly
    acknowledges that this General Release includes, but is not limited to, Mr.
    Moore's intent to release the Company from any claim relating to his
    employment at the Company, including, but not limited to, tort and contract
    claims, arbitration claims, statutory claims, claims under any state or
    federal wage and hour law or wage collection law, and claims of age, race,
    color, sex, religion, handicap, disability, national origin, ancestry,
    citizenship, marital status, retaliation, or any other claim of employment
    discrimination under the Age Discrimination In Employment Act (29 U.S.C.
    Sections 626 et seq., "ADEA"), Title VII of the Civil Rights Acts of 1964
    and 1991 as amended (42 U.S.C. Sections 2000e et seq.), the Moore
    Retirement Income Security Act (29 U.S.C. Sections 1001 et seq.), the
    Consolidated Omnibus Budget Reconciliation Act of 1985 (29 U.S.C. Sections
    1161 et seq.), the Americans With Disabilities Act (42 U.S.C.  Sections
    12101 et seq.), the Rehabilitation Act of 1973 (29 U.S.C. Sections 701 et
    seq.), the Family and Medical Leave Act (29 U.S.C. Sections 2601 et seq.),
    the Fair Labor Standards Act (29 U.S.C. Sections 201 et seq.), the
    Annotated Code of Maryland, and any other law prohibiting employment
    discrimination.

    Mr. Moore represents that he has not heretofore assigned or
    transferred, or purported to assign or transfer, to any person or entity,
    any claim against the Company or portion thereof or interest therein, and
    that any such claim is not assignable or transferable.

11. Agreement not to sue.  Mr. Moore agrees not to sue the Company or to join
    in any lawsuit against the Company, or any other person or entity specified
    in Paragraph 10, concerning any matter which arose prior to the date of
    this Agreement.  Mr. Moore further agrees and covenants not to make, file,
    assist or encourage others in making or filing any lawsuits, complaints, or
    other proceedings, including but not limited to any


                                                                    Page 5 of 8

<PAGE>   6
    suits in the local or state courts, the United States Federal District
    Courts or any other court, against the Company, or any other person or
    entity specified in Paragraph 10.

12. No wrongdoing.  Mr. Moore agrees that the consideration set forth herein is
    not to be construed as an admission of any wrongdoing or liability on the
    part of the Company under any statute or otherwise, but that on the
    contrary, any such wrongdoing or liability is expressly denied by the
    Parties.

13. No prevailing party.  Mr. Moore agrees that neither this Agreement nor the
    negotiations in pursuance thereof shall be construed or interpreted to
    render Mr. Moore a prevailing party for any reason, including but not
    limited to an award of attorney's fees or costs under any statute or
    otherwise.

14. Confidentiality.  Mr. Moore agrees that the terms, provisions, and
    conditions of this Agreement and the negotiations in pursuance thereof are
    strictly confidential, that he may not disclose them to any person or
    entity and that the Company will not disclose them except as required by
    law, provided that Mr. Moore agrees that he will provide, and the Company
    may provide, a copy of Paragraph 3 to any future employer.  Mr. Moore
    further agrees that a violation of the terms of this Paragraph regarding
    the confidentiality of this Agreement is a material breach of this
    Agreement, entitling the Company to recover any payments made to Mr. Moore
    under this Agreement, to stop any payments or obligations owing under this
    Agreement, to recover the costs and attorneys' fees the Company incurs to
    recover under this paragraph and to obtain injunctive, monetary or other
    relief permitted by law.

15. No comment on Company.  Mr. Moore agrees that after the date of the
    execution of this Agreement, he will not, either by conversation or any
    other oral expression, by letter or any other written expression, or by any
    other deed or act of communication (including, but not limited to allowing
    himself to be referred to or quoted as the source of information) to the
    public or to any individual person or entity or groups of persons or
    entities, specifically including but not limited to such persons or
    entities as are, have been, or may be, employees, customers, or business
    associates of the Company, disparage, criticize, condemn or impugn the
    reputation or character of the Company or any of the actions or writings,
    specifically including but not limited to any of the policies, practices,
    procedures or advertisements, which are, have been or may be taken or
    produced by the Company or its predecessors, subsidiaries, parents,
    successors, successors in interest, assigns, trustees, officers, directors,
    agents, attorneys, servants or employees on behalf of the Company.  Mr.
    Moore understands that by agreeing to the provisions of this Paragraph, he
    is waiving rights guaranteed by the First Amendment of the United States
    Constitution and State counterparts.  Mr. Moore further agrees that a
    violation of the terms of this Paragraph is a material breach of this
    Agreement, entitling the Company to recover any payments made to Mr. Moore
    under this Agreement, to stop any payments, benefits or obligations owing
    under this Agreement, to recover the costs and attorneys' fees the Company
    incurs to


                                                                    Page 6 of 8

<PAGE>   7
    recover under this Paragraph and to obtain injunctive, monetary or other
    relief permitted by law.

16. Binding on successors and permitted assigns; amendments.  The Parties
    further agree that this Agreement shall be binding upon and inure to the
    benefit of the personal representatives, heirs, executors, and
    administrators of Mr. Moore (who may not assign this Agreement) and the
    assigns, affiliates, successors, officers, purchasers, agents,
    representatives, directors and employees of the Company, that this
    Agreement contains and comprises the entire agreement and understanding of
    the Parties, that there are no additional promises or terms of the
    Agreement among the Parties other than those contained herein, and that
    this Agreement shall not be modified except in writing signed by each of
    the Parties hereto.

17. Governing law.  The Parties further agree that this Agreement and the
    rights and obligations hereunder shall be governed by, and construed in
    accordance with, the laws of the State of Maryland regardless of any
    principles of conflicts of laws or choice of laws of any jurisdiction.  The
    state courts of the State of Maryland and, if the jurisdictional
    prerequisites exist at the time, the United States District Court for the
    District of Maryland, shall have sole and exclusive jurisdiction to hear
    and determine any dispute or controversy arising under or concerning this
    Agreement.  Mr. Moore consents to the jurisdiction of such courts in any
    such suit, action or proceeding and waives any objection he may have to
    venue in such courts.

18. Interpretation.  If any terms of the above provisions of this Agreement are
    found null, void or inoperative, for any reason, the remaining provisions
    will remain in full force and effect.  The language of all parts of this
    Agreement shall in all cases be construed as a whole, according to its fair
    meaning, and not strictly for or against either of the Parties.

19. Cost of enforcement.  If the Company seeks a restraining order, injunction
    or any other relief, including but not limited to damages, against Mr.
    Moore as a result of his breach of any provision of this Agreement, and
    recovers any such relief, Mr. Moore shall reimburse the Company for the
    attorney's fees, costs and other expenses it incurred obtaining that relief
    (even if other relief were denied).

20. Understanding of agreement.  Mr. Moore represents that he has read this
    Agreement, that he understands all of its terms, that he had a reasonable
    amount of time to consider his decision to sign it, that he had the
    opportunity to discuss the terms of this Agreement with an attorney of his
    choice, that in executing this Agreement he does not rely and has not
    relied upon any representation or statements made by any of the Company's
    agents, representatives, or attorneys with regard to the subject matter,
    basis, or effect of the Agreement, and that he enters into this Agreement
    voluntarily, of his own free will and with knowledge of its meaning and
    effect.


                                                                    Page 7 of 8

<PAGE>   8
